Methyldopa (Aldomet) -- Centrally acting antihypertensive agent widely considered the first-line
agent for treatment of hypertension during pregnancy.
Studies have revealed no adverse effects on cognitive development up to the age of 7.5 y among
children with in utero exposure to methyldopa.
Hydralazine (Apresoline) -- Intravenous form is useful when treating severe hypertension due to
preeclampsia/eclampsia.

step by step is (MKSAP, in Neurology, parkinson's dis, Table, 39):
Hallucinations, delusions TX: (step by step):
1). Discontinue non-levodopa drugs, if failed..

polymyositis -- weakness and muscle pain and tenderness..
FM is almost always dx in a <40yo and ESR=NL. PM and PMR are dx in the same age range, but PM

///////////////////////
polymyositis has specific weakness which always demonstrated by something like cannot raise from
chair or cannot climb stair because of their severe proximal muscle weakness. Polymyositis pt does
not complaint pain that much although they have tenderness in PE. the diagnostic for polymyositis is
EMG, biopsy and CK etc. Fibromyalgia is a very vague similar to chronic fatigue syndrom. those pt

Valproic acid (dapakote)is generally regarded the drug of first choice in primary generalized epilepsy,
particularly in patients with more than one seizure type, because of its broad spectrum of activity.
Lamotrigine and topiramate also have a broad spectrum of activity and show promise in the
management of these patients. Phenytoin, carbamazepine, and phenobarbital are effective in
primary generalized tonic-clonic seizures but are ineffective against generalized absence and
myoclonic seizures. Felbamate is effective in primary generalized seizures but is relegated to the
refractory population because of its potential for toxicity
///////////
BLL <10 mcg/dL: No action is required.
BLL 10-14 mcg/dL: Obtain a confirmatory venous lead level within 1 month. If the BLL is still within
this range, patient education about lead exposure is needed, and the BLL test should be repeated in
3 months.
BLL 15-19 mcg/dL: Same as #2, but repeat the BLL in 2 months.
BLL 20-44 mcg/dL: Obtain a confirmatory venous BLL in 1 week. If the BLL is still within this range,
assess complete medical, nutritional, and environmental hazards. Environmental evaluation by the
local health department is also needed. A 2001 large-scale study reported no improvement in
neurologic and behavioral test scores after succimer chelation of children with BLL in this range.
BLL 45-69 mcg/dL: Obtain a confirmatory BLL within 2 days. If still within this range, undergo
complete evaluation as in #4. At this level, chelation therapy is recommended. Treatment should be in
a lead-free environment. If this is not possible, hospitalization is necessary. Chelation can be started
with oral succimer, or, if the patient is hospitalized, calcium disodium edetate (calcium EDTA) can be
used. These agents have potential toxicities, and monitoring of the CBC, electrolytes, and LFTs is
necessary.
BLL >70 mcg/dL: Hospitalize, obtain a confirmatory venous BLL, and initiate chelation with
dimercaprol and calcium EDTA. Because calcium EDTA does not cross the blood-brain barrier, its use
as the only agent in this situation is not recommended because of the possibility of lead redistribution
from the soft tissues to the CNS. Pretreatment with dimercaprol (which crosses the blood-brain
barrier) is recommended.
////////////////The measles (rubeola) vaccine recommended for use in this country is a live
attenuated vaccine. It is recommended for use at 15 months of age, but whenever there is likely
exposure to natural measles, infants as young as 6 months should be vaccinated and then
revaccinated at 15 months to ensure protection. Exposure to measles is not a contraindication to
vaccination, and if the vaccination is given within 72 hours of exposure, it may provide protection.
Studies indicate that measles vaccine, by protecting against measles, significantly reduces an
individual's chances of developing SSPE, a "slow virus" infection of the central nervous system
associated with a measles-like virus.

Eye movement and pupil size, such as miosis in opioid, organophos intox and barbiturate coma, or
pontine lesion etc and mydriasis in TCA, amphetamin/cocaine, higher level herniation, brain
hemorrhage etc. And that bilaterally dilated and fixed pupils are due to inadequate cerebral
perfusion.
nystagmus: Vertical -damage to the brain stem; horizontal more related to drug.
Cushing's triad, which includes bradycardia, hypertension, and a change in respiratory pattern, is
seen in head injuries with increased intracranial pressure (ICP).
Head injuries rarely cause hypotension therefore, if it does, other causes of hypotension must be
sought.
if pt injested TCA, neither serum or urine give you any good information, because the level does not
correlate with symptoms, EKG is key in TCA

In an unconscious pt with an intact brain stem, the fast component of the nystagmus disappears ,so

I think if the pt. is UNCONCIOUS the nystagmus disappears and eyes are tonically deviated to the side
of applied irrigation for 2/3 min. If in this case nystagmus is present, that means pt. is concious.

//////////Tourette's disorder is a neuropsychiatric disorder characterised clinically by motor and
vocal tics, which may be associated to conductual disorders such as obsessive-compulsive disorder
(OCD) and attention-deficit hyperactivity disorder (ADHD). Although the neurochemistry of
Tourette's disorder is not well known, there are some effective therapies for tics, OCD and ADHD.
However, these are not devoid of adverse effects. Tics only require treatment when they interfere
with the functioning of the patient. If therapy is needed, monotherapy at the minimal effective dose
is desirable, but some patients may require two or more drugs. The most frequently used drugs for
tics are antipsychotics (mainly pimozide and haloperidol) and clonidine ..The drugs of choice for OCD
in patients with Tourette's disorder are the selective serotonin reuptake inhibitors (SSRIs), although
the tricyclic antidepressant clomiplamine, which inhibits both serotonin and noradrenaline uptake, has
also been found to be useful. ADHD can be treated with some psychostimulants, mainly
methylphenidate, although these drugs must be used with caution. Other potentially useful drugs for
the treatment of ADHD in patients with Tourette's disorder are clonidine, guanfacine, selegiline,
some tricyclic antidepressants, sertraline, pimozide and clonazepam. Finally, the potential value of
some nonpharmacological therapies (hypnotherapy, biofeedback, conductual therapies,
electroconvulsive therapy, acupuncture and surgery) is briefly reviewed.

There are three basic options for the treatment of scoliosis. These include observation, bracing, or
surgery. Alternative treatments, although currently popular, have no proven benefit in the current
orthopedic scientific literature. Observation is the preferred management choice for curves at low
risk of further progression, and where the natural history is favorable. This would include curves less
than 20o, or curves under 40o after the child has reached skeletal maturity. Bracing is preferred for
curves in which there is documented progression of the curve and where the child has not reached
skeletal maturity. These curves are at risk for progression, and the goal of the bracing is to stop this
progression. The final option for scoliosis is surgical treatment. This is generally reserved for curves
which are out of balance or those in excess of 50o. Curves of this magnitude tend to progress after
the onset of skeletal maturity and ultimately cause significant functional compromise.
according to this the patient shoud be followe for 6 months & if any progression is found then
suggest a brace !!

Answer is IGA deficiency Patients with IgA deficiency may develop antibodies to IgA, and can have
severe reactions (including anaphylaxis, a potentially life-threatening allergic reaction) to
transfusions of blood and blood products. If transfusions are necessary, they should ideally come
from another IgA-deficient individual.

1) THE main DIFFIRENCE between TTP and HUS is lack of Neurological involvement in
HUS....otherwise same as both have inc BUN/CRETINE both have INC LDH both ha
THROMBOCYTOPENIA both have MICROANGIOPATHIC HEMOLYTIC anemia......both have
SHISTOCYTES on periphral bloood smear...v imp for exammmm REMMBER BOTH HAVE NORMAL
COAG AND NORMAL OTHER CELL LINES...
2)INC PTT IN CLASSIC HEMOPHILIA AND ITS XLINKED...TREAT WITH FACTOR 8 AND IF IT DOESNT
CORRECT PTT THEN IT MEANS THAT PT HAVE ANTIBODIES AGAINST FACTOR 8 WHICH CAN OCCUR
IN 10% OF TH E CASES AND TEST THIS WITH MIXING STUDY MEANING WHEN U WILL MIX PTS
BLOOOD WITH FFP OR NORMAL BLOOOD NOTHING WILL CORRECT PTT IT WILL STILL INC
...TRETAMENT OF THIS WILL B CYCLOPHOSPHAMDIE ALONG WITH PREDNISONE
3)MOST COMMON CONGENITAL BLEEDING PROB IS WITH VON VILLIBRAND DIASES ITS
AUTOSOAML DOMINENT...AND IT WILL INC BLEEDING TIME..INMILD CASES U CAN GIVE PT
DESPOPRESSIN ,,,AND IN SEVER CASES CRYO WILL HELP...DONT GIVE DESMO IN SEVER CASES IT
WILL MAKE IT WORSE..
4)DESMOPRESSINIS ALSO GOOOD FOR MILD CLASSIC HEMOPHILIA A...
5)IN ITP THERE WILL B MEGAKARYOCYTES ONPERIPHRAL BLOOOD SMEAR BCZ THERE IS INC
RATE OF DISTRUCTION OF PLATELETS AND DEC FORMATION OF PLATELETS DUE TO AUTOIMMUNE
PHENOMENON, ANTPLATELET IgG ANTOBODIES DESTRY ALL PLATESLETS SO THESE PTS R MORE
PRONE TO HAV EMUCOSAL BLEEDING LIKE THEY WILL HAV E MENORHAGIA,OR
EPISTAXIS.....FORTREATMENT IST TRY WITH PREDNISONE IT HELPS ALOT BY INC THE PLATELETS
itworks by dec the affinity of platelets to activated macrophagesin th e spleen and steroid also dec
the binding of autoantobodies toplatelets....tretament always start with low dose of platelets it will
inc th eplatelets numb but if u hav eto keep thept on prednisoneor u hav eto inc the dose then do
splenectomyis the definate treatmentofitp if they ask u in step 3,,,,but make sure that u give
pnumovac and h influenza vac 2 wk prior to splenectomy,other drugs that use when platelets r low
and causing bleeding or if pt is going for urgent surgery is ivig..its v expensive so only reserve for life
thretening bleeders and its always given slow and never in ppl who have igA defiency bc zthey will die
from anaphylaxis...another imp point is that when pt cant go for splenectomy or cantbon prednisone
or cant afford 5 k dollerivig give him danazol,or rh gam its helpful tooo...som e tried inflaximab group
its helpful but infectionis the side efefct....so watch for that...if u c ccs in exam which most of u
willl..... just treta as an out pt with prednisone and call pt in 2 wks and when platelets above 50 taper
prednisone and advise for no contact sport..and pt teaching about diease ...v imp...
6)dic is dif from sub acute dic in thatpttis normal and fibrinogenis normal...and remmber in dic treat
the underlying cause...
never give aminocaproic acid in dic without heparin bc zit cause severe thrombosis...
7)liver disease have both prolong pt and ptt but fibrinogen level is normal...ff will correct th
ebleeding..
8)the dif bet the vitamin k deficiency and dic is noraml platelets and normal fibrinogen vit k will help....
9)if platelet r 10 k still u can perform splenectomy so never ever give platelets in itp when its in
exam..bcz it will b destryed by the antibodies...
10)inmy exam they ask that baby had circumcison and lost lots of bloood on lab hisptt was 100 an his
bleedint time was 12....and mom said his uncle has sam e prob he bled in suregry and after
surgery...whatu will do u will check factor 8and 9...its dic,its ttp,its itpand blabla...
11)remmber factor x11 deficiney u wont have bleeding just inc ptt they canhave surgery without any
prob its also callled hadgman factor deficiency..
12) ifpt is having factor 13 deficiency.u will hav e normal coag but still u will hav e bleeding....so
remmebr these clues they will help u to exclude wrong choices in exam...
13)lupus anticoagulant antibodies is v imp subjects so u have to read about it.....its igG or igM
antobodies taht produce aprolonged pttby binding to phospholipids,its present in 10% pt of sle and is
characterized by recurrent abortion,and thrombosis .there is no bleeding unless second ry factor is
presenttaht cause bleeding,the prolonged ptt will failed to correct with mixing study so that is a clue
for diag....the russell viper venum isgood and senstive assey and is diag of lupus
anticoagulant...antiphpjolipid and lupus anticoagulant will cause the false positive vdrl...u can suspect
lupus anticoagulant when inc ptt but no bleeding and vdrl is in and anticardiolipid and natiphospholipid
positive...predison is th ebest treatment and give heparin if thrombosis is suspected....
14)autologous bloood can b given to pt for surgery and it can b stored for upto 35 days...it dec the
chance of infection and reaction..
15)i pack of rbc pack can raise the hct by 3-4%and prbc is used to raise hct ...not the whole blood
that is reserved for sever hypovolemic pt...
16) dont transfuse awake juhuwa witness against his will but for a kid go ahead and transfuse if
urgent or in nonurgent situation just tak e court oreder...ifkid belongs to juhuwa witness
17)always remmber when ever kid is in the womb mom will give consent for every thing evenif she is
competent and refusing for csection and endangering her baby thats fine u just listen to her an d
respect her wish..but as soon as she deliver she has no longer authority if child lif eis in danger....but
for non urgent cases we stilll need her consent even if she is in jail or drug addict .....
18)febrile bloood transusion reaction pt need leukopooor bloood
19)for graft verses host reaction u need to give iiridiated bloood next time..
20)HIT need that u d/d heparin and coumadin both and start with leupridine...inc risk of thrombosis
with the HIT...plez read more from wash manual ....21)...in cases of hemoglobuburia weather its due
to rhabdoor bloodo transfusion reaction give vigrous hydration with n/s and mannito or lasix...so
hemoglonuria will not damage kidney tubule....bcz atn will cause rf sooon..if will not go aggressive
hydration v imp for exam....
21)ist day jaundance is always due to abo imcompatibility
22) if husband is onegative and wife is tooo no prob baby will b normal..(.cam e in my exam..)..case
senario was that a gal is pregnantand her rh is negative and her b fd is rh positive and they tell s u in
sep setting that this babyis not my b fd but my ex and he is rh negative what u will tell her....
23)delayed transfusion reaction is due to duffy,kell and c,e loci of rh system..they cause delayed
reaction after 8 to10 days of transfusion..
.
24)i unit of platelet will inc 5 k of platelets usually we giv e 6 pack..
25)fever chillsl and sever backach eis due to heamolytic reaction,stop transfusion and give ns bolus
and lasix..flush th ekid so no damage to tubule and no renal failure other prob is dic....
26)kid if they have dirrhea due to slmonella sheggella or due to e coli they will most like ly have hus so
keep that inmind in exam they ask that akid ate hamburger while his father was stilll barb qing...an

Anthrax - a guide for doctors and patients
Introduction:
Anthrax is a bacterial disease. It is caused by a bacteria that belongs to the same family as E. coli. called Enterobacteraciae. It is not a virus. Unfortunately, it has become a recent threat as it can be used for biological warfare.
The bacteria:
It is a rod shaped bacteria with rounded edges. It cannot be seen by the naked eye. Labs need a microscope to see it.
When doctors check or screen for bacteria, they stain the specimens commonly with a simple technique called gram staining. There are very few bacteria that are rod shaped and test positive on this test. Fortunately - for diagnostic purposes, anthrax bacteria test positive. This immediately raises a flag.
Modes of spread:
It is spread by its spores that can survive harsh natural conditions for years.
It may be transmitted by infected or contaminated animals and animal products, insect bites, inhalation or ingestion.
Spread of anthrax usually does not take place from person to person except where the patient has skin lesions. It could however take place by handling contaminated articles.
In the Florida cases, it seemed to be transmitted by exposure from spores that were sitting on the computer keyboard (I am looking at my own keyboard as I type this).
I do not want people to panic because Florida is currently one of the most prepared states in the United States to tackle this problem. In my own office, we have at least a hundred doses of medicines that tackle anthrax. I am sure other doctors are prepared too.
Types of disease:
It is seen in three main forms.
Skin (cutaneous), intestinal (gastrointestinal), and its most dangerous form - lung infection or pneumonia (pulmonary).
Cutaneous anthrax is the most common manifestation of infection with B. anthracis. Inhalation (pulmonary) anthrax occurs in persons working in certain occupations where spores may be forced into the air from contaminated animal products, such as animal hair processing. Occupational risk groups include those coming into contact with livestock or products from livestock, e.g., veterinarians, animal handlers, abattoir workers, and laboratorians.
A patient with this form of anthrax may present with a blister with central denting and surrounding swelling that cannot be indented.
This is full of the antrax bacteria, making it highly infective as it sheds a lot of bacteria.
The intestinal form shows up as diarrhea and fever. Fortunately the commonest family of drugs used to treat this type of illness even in the non-anthrax condition treats anthrax as well.
The lung form of the disease begins abruptly with high fever and chest pain. It quickly turns into a bleeding type of illness and is frequently fatal. These cases are not highly infective.
If untreated, anthrax in all forms can lead to the bacteria entering the bloodstream and quickly - death. Early treatment of cutaneous (skin) anthrax is usually curative, and early treatment of all forms is important for recovery. 25% to 75%. of patients with gastrointestinal (intestinal) anthrax will die. Almost 90 - 100% of those with lung anthrax will die.
Preventing disease and its spread:
Anthrax in the veterinary world commonly affects herbivorous animals. Human immunity against anthrax is higher than the herbivores. This does not mean that vegetarians are any less immune to the bacteria than non-vegetarians.
We must identify what common things that come in contact with many hands in a day's time and be cautious about their safety. I am going to list a few here.
Currency notes and coins, Paper files and inter office mail envelopes, Card swiping areas, e.g. time card machines and credit card machines, Support bars into a bus, Door knobs, Water fountains, Gas station vending handles, Vending machines, Public telephones, Perfume testers in a mall, Coins and tokens for a slot machine, Buttons at traffic signals used by pedestrians to get access, Library computers, books and video tapes, Rented video tapes, etc, Objects in churches that many people touch, etc.
Please wash your hands before you touch your mouth or nose after you touch something that may be contaminated. Avoid opening letters if you have a wound on your hands.
Treatment:
Early treatment is vital. Therefore you do not need to hoard a full course of the antibiotics that are effective but just the first dose alone.
Many good antibiotics are available that are approximately equally useful but Once symptoms of the lung form appear, fatality is high inspite of treatment.
Levaquin, Cipro, Tequin, avelox are good medicines that could be used.
Penicillin too is useful as are many other antibiotics.
Most commonly, the skin form comes along and one can treat that very effectively.
What should your doctor do?
Having been a licensed practitioner for over 10 years, practice of reasonable and economical medicine has now become second nature to me. I am not trying to say that what is outlined here is perfect but these guidelines will certainly help those who have not put in a lot of thought into this. If other doctors also put in thought into this, they will come out with similar answers.
If a patient wants to keep antibiotics at home for him and his family, he should only be offered dosing for 24 hours.
This means 2 tablets of Ciprofloxacin (Cipro) or 1 tablet of Levaquin or Avelox or Tequin. He should be told that this should be given if suspicion is high and the patient should be examined by a doctor soon.
Giving out long courses are going to create a shortage and thus further panic in the community.
If the doctor has a suspicion of anthrax in the patient, he should immediately draw and keep blood from the patient and then administer the first dose of the antibiotic immediately.
If it is a skin lesion that the doctor sees, he should take a scraping from the skin lesion and send part of it for a Gram stain and another part for culture. Antibiotic of course should be given immediately.
Doctors also should try to avoid use of these antibiotics in conditions where other antibiotics are equally effective.
What does it mean that the cases are due to genetically un-altered bacterial strains?
Since the cases had the above type of strain, it is unlikely that these are from terrorists. It is more likely that someone who has animals got that strain and now has mailed the stuff to different people across the country. One should look through veterinary records and match up people who owned animals that died of anthrax in the Tampa-bay area. I could certainly be wrong but I rarely am.
How concerned should we be about the future:
Not very. I am not an astrologer nor a psychic but seeing that these cases have been from unaltered bacteria, I feel that these are not well prepared terrorists left around. Had this attack come from well prepared terrorists, we would have seen very communicable, genetically altered anthrax strains. They would have used their biowarfare material already within this one month. Regardless, almost all doctor's offices are well prepared with antibiotics.
Vaccine:
In the civilian world, the health departments are most likely going to be the first to recieve vaccine supplies. I think that many of us doctors should volunteer and offer to give out the vaccines if that is decided by the government. Our clinic has already registered with the health department for this purpose.

==========
Three vaccine can induce anaphylactic reactions in egg-allergic people: INFLUENZA, YELLOW-FEVER and MMR.
The MMR and yellow fever still can be given in egg allergic people.
Varicella zoster vaccine is given at age of 1 year! (with the MMR).
Influenza vaccine ==> all people > 50 YEARLY
Penumococcal vaccine ==> for adults above 65 with chronic diseases/immunocompromised
MALE HOMOSEXUAL..What vaccines you give beside Hepatitis B? Hepatitis A !!! (becuase hepatitis A transmits through the faeces like feco-oral or feco-mucosal route...Male homosexual are thus subject to Hepatitis A).
60 year old patient ..came with positive occult blood stool..sigmoidoscopy shows hyperplastic polyp..next step:
a-colonoscopy
b-do nothing
The answer is do nothing..Itis hyperplastic polyp..
60 year old patient ..came with positive occult blood stool..sigmoidoscopy shows tubular adenoma polyp..next step:
a-colonoscopy
b-do nothing
The answer is colonoscopy...It is tubular adenoma..It has risk of malignancy. So, you have to make sure that there are no more tubular adenoma polyps..sigmoidoscopy screens the descending colon only and doesn't reach the rest of the colon..so, colonoscopy should be the next step.
PAP shows ASCUS ==> Repeat test in 4-6 months
LGSIL/HGSIL on PAP ==> colposcopy and followed by cervical biopsy.
ITP ==> steroids are the first line. IVIG is the second line.
TTP/Gullian Barre ==> plasmapheresis
When the patient is in severe depression/suicidal tendency, he is not compotent:
30 year old man found on the floor with empty bottle of valium. A suicidal note was found saying that he wants to die peacefully and doesnot want any heroic procedures to save his life. Next step:
a-Flumazine i.v
b-Intubate and move to the ICU.
Choose B
For any drug overdose, do not choose the option of the anti-dote/the antagonist..remove the drug first by charcot/gastric lavage unless contraindicated.
Acetaminophin overdose..next step:
a-N-acetylcystiene iv
b-gastric lavage
Choose B
Don't afraid to give morphine for the pain management in patients with terminal stage of their cancers:
..but it should be under monitoring to prevent respiratory depression!!
75 patient with pacreatic cancer and severe back pain ..next step:
a-morphine intrathecal
b-morphine i.v every 3 hours
c-morphine i.v on needed basis
d-morphine i.v in a monitored bed.
Jump to D
Emancipated minor is the minor who lives alone/married/works
Pregnant minors are not emancipated but have the excetion of signing the consents!
A 16 year pregnant girl need Cesearan section for delivery ..who signs the consent?
a-In most states, she is emancipated minor.
b-In most states, she can sign the consent
Point your arrow to B
Jehovah's witness refuses blood transfuion..His Bp is 50/0..next step:
a-do nothing
b-iv fluids
Respect the autonomy but tries to do any supportive measure outside the conflict!! so jump to B
Do not respect the patient's wishes in organ donation if they parents refuse the donation even if he has the organ donation card! This is the only excetion for the patient's autonomy after hhis brain death.
The spouse is the next after the patient (not his parents or siblings). Ask the wife for any consents if there is no guardian or advance directive!!
Treat keloid by intralesional steroids. The same thing for alopecia aerata (NOT topical!!)
Emergent reversal for warafin overdose is FFP (not Vit K) while emergent reversal of heparin is protamine sulphate (not FFP!!..The FFP is c.i.)
If the Q is clueless..choose the most common
70 yo patient with weight loss...next step; CXR (to exclude lung cancer which is the most common malignancy)
70 yo patient with fatigue...CBC (to detect iron deificency anemia..followed by colonoscopy becuase lower GI bleeding is the most common cause of iron deficiency in the US..NOT NUTRITIONAL CAUSE!)
EFFECTs of OCP:
HDL LDL Glucose TG
a low high high high
b high low high normal
c high high normal normal
d normal normal normal normal
e normal normal high high
The answer is E why?
Remember that estrogen increases HDL but decreases LDL
Progetreone decreases HDL and increases LDL
Their combined effects is nill!!keeping the levels of LDL and HDL normal
TG is elevated and impaired glucose tolerance!!
Patients with adenomyosis/endometriosis/leiomyomata uteri (refused surgery)..What is the medical treat? OCP. Remember all these cases are caused by state of hyperestrogenism..but you still have to give OCP..not progestrone only.
Patient with rheumatoid arithritis...refused to take steroids..The alternative drug should be: METHOTREXATE
Patient with SLE...refused to take steroids..The alternative drug should be: CYLCOPHOSMAIDE
Patient with Crohn's disease..The first line is s-ASA with metronidazole or cirpofloxacin...Steroids are SECOND LINE..AZATHIOPRINE or ^-Mercaptopurine are THIRD line. INFLXIMAB is the last line OR for the treatment of FISTULAS!!
Treatment of IBS (Irritable bowel syndrome)?? FIBER+ ANTICHOLINERGIC DRUGS like hyoscine
GERD ==> First line is therapeutic trial of H2 blockers , followed by Proton-pump inhibitors. If fails, go to 24-hr esophageal PH monitoring. Don't forget the life style modification before any pharmacologic therapy.
A patient presents with heartburn and regurgitation..
First step..Life style modifications..
Failed..
The patient can be tried on H2 blockers/anatcids/promotility drugs..
Doesnot respond..
Trial of omeprazole..
No response..
24-hour esopaheal PH monitoring/ Esophageal acid infusion test (Bernstein test)
Proton pump inhibitors are indicated for use in severe GERD or if it is resistent to other treatments.
Fundoplication is the last resort.
Question examples::::
45 year old obese patient came to you with epigastric pain..first step:
a-EKG
b-CXR
c-Zantac
EKG first...Epigastric pain can be cardiogenic!!!
Next step:
a-Lansoprazole
b-Zantac
c-Counselling the patient about losing wieght, bed head elevation..
The answer is of course C
Came to your office 4 weeks later and the heartburn persists:
next step
Zantac or Tagamet (H2 blockers) for 8 weeks
Came back with no response..next step:
a-Omperazole
b-Increase the dose of Zantac
c-Fundoplication
Choose A
The patient's pain is improved. The patient came to you after five years..next step:
Endoscopy
To rule out Barett esophagus!!!!!!1 The most common LONG-TERM complication of GERD!!!!
well in IBS, the anticholinergics are not given routinely. Only if it is IBS-diarrheal predominant. ANd also when the urge occurs acutely after the meals( In which case loperamide is given).
=========
Immunization & Pregnancy..
The following vaccinations should not be given during pregnancy becuase they are live attenuated virus vaccines:
1-Mumps/Measles/Rubellla
2-Yellow fever
3-Varicella
REMEMBER>>>
A prgenant in her 2nd trimester exposed to a child with Varicella one day age. You checked her serum for varicella antibodies titre and it was negative..Give VZV ig (not vaccine) ..It should be given within 96 hours of exposure.
The mother ask you: Does the VZIG protect my fetus againts infection? NO. VZIG is given to prevent MATERNAL NOT CONGENITAL/FETAL infection!. The congenital varicella syndrome results from exposure during the first 16 weeks of pregnancy
These vaccines can be safely given and their indications are not aletred by pregnancy:
1-Pneumococcus (polysaccharide)
2-Meningococcus (polysaccharide)
3-Rabies (killed virus)
4-Influenza (inactivated virus)
5-Hepatitis B (purified surface antigen)
6-Hepatitis A
7-Tetanus-Diphtheria (toxoid)
LEAVE STATISTICS ALONE IF UWILL B MASTRE U WILLL NEVER GET WHAT THEY WILL GIVE U INEXAM SO FORGET ABOUT IT ITWONT B MORE THAN 6-7 QS MAX..
READ PEADS.....ALOT GYNE AND SURGERY JUST IMP STUFFF....DO ALOT OF CDS FINISH THEM ALLL 3 TIMES ...LIKE QBANK,ALERT ,ACE THE BOARD,IST PASS,CCS CDS,U WILL MAKE IT
IF UWONTCLLL CONSULT OR IF U CANT FIGUREOUT WHAT S THE DIAG THEY WILL FORGIVE U BUT IF UORDER CT DIRECT INSTEAD OF XRAY THEY WILL CHEW U....THEY SAID THAT IN THEIRORIENTATION LECTURE IN CD...SO THINK LIKE PT...HOW U WOULD FEEL IF U GET THIS MUCH BILLL ..SO COSTEFFECTIVENESS IST
Metastatic prostate cancer
Spine metastasis is urgency...Radiation first to reduce the compression.
To relieve the spine compression:
Dexamethason i.v (systemic intravenous NOT intrathecal....A real Q!!)
Followed or accompanied by spine radiation
Laminectomy is the last resort
Total orchiectomy is the Rx for metastatic prostate cancer in general.

Know different problems faced by health care workers who are either carriers or get exposed to different Bacteria/viruses.
Explanation
The discussion will focus on HIV & HBV exposure, Meningococcal exposure, Needlestick injury, MRSA & VRE carrier states.
All of us should be immunized against Hepatitis B.
HIV does not preclude a doctor or nurse to discontinue their job.
A needlestick injury must be carefully evaluated. If a needle contaminated with a patient,s body fluid enters a healthcare worker, the employer is responsible for all the expenses. Anti HIV medications MUST be offered within 4 hours. SOLID needles (eg lance for accucheck) have not been shown to transmit HIV. At least 2 anti HIV drugs should be offered. If the source patient has been on Zidovudine, the victim should also be offered a 3rd anti HIV drug as well. These should be taken for 1 month & victim to be sexually protective for 6 months. The source & patient needs to be checked immediately and in 6 weeks, 12 wks & 6 mo- and the source patient has no right to refuse but we generally get a consent form signed.
There was recently a question on the risk of HIV transmission - it is 1 in 200 encounters. The risk of Hepatitis B on the other hand is 1 in 20 encounters. This is also called the transmission rate.
Meningococcal prophylaxis must be given to close contacts of the patient with meningococcal meningitis. The drug of choice is Rifampin for 2 days. A good alternative is Ciprofloxacin - single dose but this cannot be given to patients under the age of 17.
MRSA & VRE carriage states are no longer of any isolation benefit. Mupirocin cream is good for MRSA eradication from the nostril.
Recognize the manifestations of carpal tunnel syndrome.
Explanation:
Pain, tingling and numbness in the median nerve distribution (lateral 3 and a half fingers) but may go up as high as the shoulder.
Worst after sleep because of abnormal positioning as one sleeps. Tinel's(tingling on tapping over course of median nerve at the wrist) and Phalen's(tingling on keeping the wrist hyper-flexed for a minute or two) signs may be elicited.
Diagnosis is clinical but Nerve Conduction Study confirms the diagnosis.
First line therapy is wrist splints during sleep.
If not effective then try hydrocortisone injection under carpal tunnel
If Motor signs are present at any time- confirm diagnosis and operate for release of carpal tunnel.(minor surgery).
FOR AA October 2 2003, 11:27 AM
I have this real exam question. Presentation is CTS carpal tunnel syndrome + atrophy of the affected hand =
Treatment? splint, steroid, surgery.thenar muscle wasting is an indication for surgery--kaplan
Recognize the complications of Aminoglycosides
Explanation
Aminoglycoside antibiotics are extremely useful in serious infections. Unfortunately they have a very narrow therapeutic index. The most important question asked on them is the adjustment of the dose amount and dose interval based on the Trough and peak levels.
There are 2 levels measured - the peak and the trough. The peak level is measured 1 hour after the 3rd dose is given and the trough is measured just before the next dose (4th dose) is given.
Higher the amount in each dose, higher will be the peak. The efficacy is related to its peak level. If it is found to be lower than the recommended value, please increase the dose of each shot to ensure that the person gets the most benefit from the drug (It also improves the post antibiotic effect of Aminoglycosides).
The toxicities of Aminoglycosides are related to its trough level. This is related to the time interval between doses (Shorter the interval, higher the troughs & higher the chances of toxicity therefore if troughs are too high, please increase the interval between the doses to decrease the trough and its related toxicities).
The toxicities of Aminoglycosides are:
Renal failure - due to tubular necrosis that can be reduced in the presence of antipseudomonal penicillins.
Muscle weakness: Direct Neuro muscular junction blockade therefore cautioned in Myasthenia.
Deafness due to cochlear toxicity
Vertigo - vestibular toxicity
Complications can be prevented by good hydration and monitoring the trough levels.
Sensitivity/specificity
Sensitivity = I am going to explain the sensitivity of a radio. There are 10 stations in the air. If it can only pick up 7 of them, it is 70% sensitive. Therefore if there are 10 cases of a disease in a population, and only 7 can be picked up by the test, it is 70% sensitive.
Specificity = Of all that are free of the disease, how many actually test negative. Now we think of a machine which opens oysters that have pearls inside. We feed it 20 oysters. It opens 8 of them. 2 out of the 8 did not have pearls. We then went on to open all those that it did not open and found 3 pearls but 9 were without pearls. Therefore the specificity is 9/11 - i.e. of the total without the pearls (11), it correctly identified 9.
DNR ¹ DNRx
DNR holds a meaning only in the code situation. When a patient has either cardiac or respiratory ARREST, we will not start CPR. That is what it means. It does not hold you back from a treatment that addresses a different issue. For example, if a patient who is DNR goes into VT where he has a pulse, you are allowed to cardiovert. If he goes into VF or pulseless VT, on the other hand, the situation constitutes cardiac arrest and you should not enter the ACLS protocol.
When a patient is DNR (do not resuscitate), many doctors hold off on vasopressors and strong antibiotics or interventions such as pacemaker or even ventilators for respiratory distress. This is incorrect. This is the kind of situation that exams like to test on.
If you think it is not appropriate to use pressors or cardioversion or antibiotics because you deem them futile, you have to address each one separately and specify on the consent form.
GENERAL INTERNAL MEDICINE
Understand the initial treatment of acute hyperkalemia if the ECG shows features of high potassium.
Explanation:
When presented with a patient with high potassium and Electrocardiographic abnormality- Calcium chloride is the drug of choice because its specific action is cardio protection. This fact is asked so commonly that you should not mix this up with the treatments given below. Calcium chloride is more readily available than Calcium gluconate.
Thereafter or in a non emergency situation one can use Insulin/Glucose combination or Sodium Bicarbonate or Albuterol (Salbutamol). These push potassium into the cells therefore reducing serum potassium.
The Potassium binding resin (Sodium polystyrene sulfonate) should be given to everyone as this is the primary medicine to REMOVE and not just cause a trans-cellular shift of potassium.
If medical measures fail - Dialyze (hemofilter if dialysis not available)
Recognize the clinical manifestations and appropriate treatment of otitis externa and malignant external otitis
Explanation:
Otitis externa is a common problem and is usually treated topically but its rarer counterpart: malignant otitis externa needs parenteral antibiotics aimed at Pseudomonas.
Otitis externa is associated with the tragus sign where -if you push or pull the external ear gently - you elicit pain.
As the skin and cartilage of the external ear are so tightly held together - the swelling tries to rip these two apart and thus is responsible for the pain associated with the condition.
Pain relief along with swelling relief is key to treatment-commonly used preparations include combo of hydrocortisone with neomycin/polymyxin..
If the inflammation becomes obvious on the pinna and is no longer restricted to the ear canal - 2 diagnoses should come to mind
1. Malignant otitis externa(MOE) or
2. Relapsing polychondritis (RP).
MOE will be suggested by the presence of Immunosuppression/Diabetes/malignancy - all of which predispose to MOE. Findings include unbearable pain and pus discharge ( If there is pus but no pain - think otitis media with ruptured tympanic membrane).
MOE is treated IN HOSPITAL with IV antipseudomonal antibiotics (Ciprofloxacin/Ceftazidime/Antipseudomonal penicillins-Ticarcillin)and usually requires surgical debridement too (unless it is very early) .
RP on the other hand is suggested by another cartilage being affected or prior history of the problem. This could be the nasal or laryngeal cartilages and is treated with steroids. These patients can go into laryngeal stridor but need not be admitted if there is no suggestion of it.

Ethical issue is respecting the patient's wishes in doing whatever possible to prolong his life
Understanding neurology!!
DECEREBRATE POSTURE indicates a brain ijury at the level of the brain stem (compare this with decorticate level which results from corticospinal tracts injury)
Corticosteroid will not add significant effect!
May be doing MRI will be help to identify any lesion at the level of the brain sten and manage the patient accordingly..(MRI is the diagnostic study)
I will go with MRI unless better options are there!

21 yr old male dead after MVA had a organ donation card which family did not know about and they refuse to allow donation so what do you do now
go ahead donate
do not donate
ethics commitee
-Patient has advance directives saying to go all the way, has been on life support for 10 days now with neurology saying no hop, family wants the vent off, what do you do
pull the vent off
cont with the vent
ethics comitee
eeg
For the first ethics Q,
Do not donate. For organ donation, family wishes are respected. This is the only excetion to override patient's wishes!. Discussed before on this forum.
For the second ethic Q,
The advance directive say go all the way..
The family says wean the patient from the ventilator..
The neurologist says no hope...
How to solve the Q?
Since the patient has advance directives ==> immediately ignore patient's family wishes and respect the decision of the advance directives.
But if you continue the ventilatory support according to advance directive wishes, the ventilation is "futile"...This means it produces no benefit to the patient. THE PHYSICIAN RESPECTS THE AUTONOMY OF THE PATIIENT IN THE WISHES WHICH ARE CONSISTENT WITH THE PROFESSIONAL STANDARD OF CARE.
If the physycian agrees that the interventions in question would be futile, the goal should be to withdraw or withhold these interventions.
So the answer is withdraw it.
No need to refer the issue to the ethics committee as the ethic principle here is clear.

ccs-Coccydynia-Diagnosis-I do not remember the choices I put rectal exam
Pain in the area of the coccyx (tailbone) is called coccydynia or coccygodynia (or sometimes a variety of other spellings). Coccydynia can be anything from discomfort to acute pain, varying between people and varying with time in any individual. The name describes a pattern of symptoms (pain brought on or aggravated by sitting), so it is really a collection of conditions which can have different causes and need different treatments.
The links on the right cover all the causes of pain on sitting that I have found in the medical literature or that people have emailed me about.
Coccydynia can follow after falls, childbirth, repetitive strain or surgery. In some cases the cause is unknown. The pain can disappear by itself or with treatment, or it can continue for years, and may get worse. It is five times more common in women than men, probably because the female pelvis leaves the coccyx more exposed. It appears that in most cases the pain is caused by an unstable coccyx, which causes chronic inflammation.
Medical trials have shown that coccydynia can be cured eventually in the great majority of cases, given the right treatment. However, finding a doctor who can do a proper diagnosis of the condition and supply effective treatments is difficult, and many people suffer years of pain.
Causes of coccydynia
The coccyx is the very bottom portion of the spine. It represents a vestigial tail (hence the common term "tailbone") and consists of four or more very small bones fused together. The coccyx articulates with the sacrum through a vestigial disc, and is also connected to the sacrum with ligaments (see Figure 1).
It is not clearly understood which portions of the anatomy can cause coccyx pain. Either the ligaments or the vestigial disc may be a cause of pain and, rarely, a primary bone tumor or soft tissue tumor can cause pain.
It is thought that the condition is more common in women because:
In women the coccyx is rotated and faces backward, which makes it more susceptible to trauma.
Women have a broader pelvis, which means that sitting places pressure not only on their ischial tuberosities ("butt bone") but also on the coccyx. (Men tend to sit only on their ischial tuberosities without a lot of pressure applied to the coccyx.)
Childbirth is a common cause of the condition
The two most common causes of coccydynia are:
Local trauma. A fall on the tailbone can inflame the ligaments or injure the coccygeal attachment to the sacrum
Childbirth. During delivery, the baby’s head rides over the top of the coccyx and can injure Causes of pain
Unstable coccyx
Spur on coccyx
Misaligned, rigid, or long coccyx
Muscle spasm or tightness
Pilonoidal cyst
Tarlov/meningeal cyst
Pudendal neuropathy
Cancer
Referred pain
Neuropathic pain
Idiopathic coccydynia
Imaginary pain
Diagnosis
A health professional diagnoses coccydynia by taking a thorough medical history and completing a physical examination. Diagnostic tests, such as x-*** or MRI, are also commonly performed in order to rule out other potential causes of the pain.
A thorough physical examination should include:
Pelvic and rectal exam to check for a mass or tumor that could be a cause of the pain
Palpation to check for local tenderness.
The most striking finding on examination is usually the local tenderness upon palpation of the coccyx. If the coccyx is not tender to palpation, then the pain in the region is referred from another structure, such as a lumbosacral disc herniation or degenerative disc disease.
Diagnostic studies that should be done include:
X-rays of the sacrum and coccyx should be done to rule out the unlikely event that either an obvious fracture or a large tumor is the cause of the discomfort.
An MRI scan is useful to rule out infection or tumor as a cause of pain
Bone scans and CT scans add very little information and are generally not done. Typically, all imaging studies will be
Conservative treatments for coccydynia
Treatments for coccydynia are usually conservative and local. The first line of treatment typically includes:
Non-steroidal anti-inflammatory drugs NSAID’s. NSAID’s (such as ibuprofen, naproxen, COX-2 inhibitors) help reduce the inflammation that can cause pain.
A donut-shaped pillow to help take pressure off the coccyx when sitting
Patience is also very important, since it often takes many weeks, or even months, for the pain to subside.
If the pain is persistent or severe, additional conservative treatments may include:
A local injection of a numbing agent (lidocaine) and steroid (to decrease inflammation in the area) can provide some relief.
Some practitioners treat the condition with manipulations.
Stretching the ligaments attached to the coccyx can be helpful.
Physical therapy with ultrasound can also be helpful.
Provided that infection and tumor has been ruled out as a cause of pain (through exam, x-***, and MRI scan), then prolonged conservative treatment is a reasonable option.
Surgical treatments for coccydynia
For people who have persistent pain that is not alleviated or well-controlled with conservative treatment, surgical removal of the coccyx (coccygectomy) is an option.
This surgery is rarely performed, and the procedure is not even included in most spine surgery textbooks. It is, however, a relatively simple operation.
Surgical approach
A one to two-inch incision is made right over the top of the coccyx, which is located directly under the skin and subcutaneous fat tissue. There are no muscles to dissect away.
The covering over the bone (the periosteum) is then dissected away from the bone starting on the back and carried around the front. Staying in this plane of tissue is very safe, and allows the coccyx to be dissected free and then separated from the sacrum.

There are three basic options for the treatment of scoliosis. These include observation, bracing, or surgery. Alternative treatments, although currently popular, have no proven benefit in the current orthopedic scientific literature. Observation is the preferred management choice for curves at low risk of further progression, and where the natural history is favorable. This would include curves less than 20o, or curves under 40o after the child has reached skeletal maturity. Bracing is preferred for curves in which there is documented progression of the curve and where the child has not reached skeletal maturity. These curves are at risk for progression, and the goal of the bracing is to stop this progression. The final option for scoliosis is surgical treatment. This is generally reserved for curves which are out of balance or those in excess of 50o. Curves of this magnitude tend to progress after the onset of skeletal maturity and ultimately cause significant functional compromise.
according to this the patient shoud be followe for 6 months & if any progression is found then suggest a brace !!

Valproic acid (dapakote)is generally regarded the drug of first choice in primary generalized epilepsy, particularly in patients with more than one seizure type, because of its broad spectrum of activity. Lamotrigine and topiramate also have a broad spectrum of activity and show promise in the management of these patients. Phenytoin, carbamazepine, and phenobarbital are effective in primary generalized tonic-clonic seizures but are ineffective against generalized absence and myoclonic seizures. Felbamate is effective in primary generalized seizures but is relegated to the refractory population because of its potential for toxicity

BLL <10 mcg/dL: No action is required.
BLL 10-14 mcg/dL: Obtain a confirmatory venous lead level within 1 month. If the BLL is still within this range, patient education about lead exposure is needed, and the BLL test should be repeated in 3 months.
BLL 15-19 mcg/dL: Same as #2, but repeat the BLL in 2 months.
BLL 20-44 mcg/dL: Obtain a confirmatory venous BLL in 1 week. If the BLL is still within this range, assess complete medical, nutritional, and environmental hazards. Environmental evaluation by the local health department is also needed. A 2001 large-scale study reported no improvement in neurologic and behavioral test scores after succimer chelation of children with BLL in this range.
BLL 45-69 mcg/dL: Obtain a confirmatory BLL within 2 days. If still within this range, undergo complete evaluation as in #4. At this level, chelation therapy is recommended. Treatment should be in a lead-free environment. If this is not possible, hospitalization is necessary. Chelation can be started with oral succimer, or, if the patient is hospitalized, calcium disodium edetate (calcium EDTA) can be used. These agents have potential toxicities, and monitoring of the CBC, electrolytes, and LFTs is necessary.
BLL >70 mcg/dL: Hospitalize, obtain a confirmatory venous BLL, and initiate chelation with dimercaprol and calcium EDTA. Because calcium EDTA does not cross the blood-brain barrier, its use as the only agent in this situation is not recommended because of the possibility of lead redistribution from the soft tissues to the CNS. Pretreatment with dimercaprol (which crosses the blood-brain barrier) is recommended.
////////////////The measles (rubeola) vaccine recommended for use in this country is a live attenuated vaccine. It is recommended for use at 15 months of age, but whenever there is likely exposure to natural measles, infants as young as 6 months should be vaccinated and then revaccinated at 15 months to ensure protection. Exposure to measles is not a contraindication to vaccination, and if the vaccination is given within 72 hours of exposure, it may provide protection. Studies indicate that measles vaccine, by protecting against measles, significantly reduces an individual's chances of developing SSPE, a "slow virus" infection of the central nervous system associated with a measles-like virus.

//////////Tourette's disorder is a neuropsychiatric disorder characterised clinically by motor and vocal tics, which may be associated to conductual disorders such as obsessive-compulsive disorder (OCD) and attention-deficit hyperactivity disorder (ADHD). Although the neurochemistry of Tourette's disorder is not well known, there are some effective therapies for tics, OCD and ADHD. However, these are not devoid of adverse effects. Tics only require treatment when they interfere with the functioning of the patient. If therapy is needed, monotherapy at the minimal effective dose is desirable, but some patients may require two or more drugs. The most frequently used drugs for tics are antipsychotics (mainly pimozide and haloperidol) and clonidine ..The drugs of choice for OCD in patients with Tourette's disorder are the selective serotonin reuptake inhibitors (SSRIs), although the tricyclic antidepressant clomiplamine, which inhibits both serotonin and noradrenaline uptake, has also been found to be useful. ADHD can be treated with some psychostimulants, mainly methylphenidate, although these drugs must be used with caution. Other potentially useful drugs for the treatment of ADHD in patients with Tourette's disorder are clonidine, guanfacine, selegiline, some tricyclic antidepressants, sertraline, pimozide and clonazepam. Finally, the potential value of some nonpharmacological therapies (hypnotherapy, biofeedback, conductual therapies, electroconvulsive therapy, acupuncture and surgery) is briefly reviewed.

If there are abnormal cells on the cervix, the doctor will perform a biopsy.
* If your test is abnormal and suggestive of cancer, you will have a colposcopy, ECC and biopsy.
In a biopsy your doctor will take a small sample of the tissue of your cervix to see if cancer cells are present.
A biopsy is the only way to tell for certain if you have precancer, true cancer, or neither.
.
Sometimes, the biopsy itself is used to treat a precancer or a very early cancer.
If the biopsy is normal and you have a normal Pap test, the Pap test will be performed again in 4 months.
If the biopsy is normal but a Pap test is abnormal, your doctor will repeat the colposcopy and biopsy.
If the biopsy is abnormal and suggestive of cervical intraepithelial neoplasia (CIN) or cancer, you will be treated for cervical cancer.
///"Is there any benefit to giving varicella vaccine to a child who's been exposed to the disease and who hasn't been previously immunized?"
IVIG is not generally recommended for everybody whoever exposed to chickenpox(large quantity of imunoglobuline is needed to modify the disease)
IT is only recommended in :
1. pregnent women after exposure
2. newborne whose mother developed chickenpox 5 days before or 2-5 days after delivery.
3 Exposed leukemic pt. any imunodeficient state, svere debilitating illness(after exposure)
Varivax can be offered within 3 days of exposure who is more than 12 month old in epidemics.
Because of benign nature of disease in healthy children vaccine is not rutine after exposure.
Yes, you immunize exposed child if prev unimmunized. March 25 2003, 2:01 AM
Will post-exposure use of the vaccine prevent or modify varicella?
Yes, the vaccine may prevent or modify illness when administered within 3 to 5 days after exposure. The ACIP now recommends vaccination of susceptible persons who are eligible for vaccination as soon as possible after exposure--ideally within 3 days but possibly up to 5 days of an exposure--to prevent illness or modify disease severity. If a person has already been infected, and the vaccine is given soon enough, disease may be modified or prevented. If the person was infected >5 days prior to vaccination, there is unlikely to be any benefit from vaccination but vaccination is not known to be harmful. Finally, exposure even in a household setting does not result in transmission 100% of the time. So, if the exposed person has not been infected, vaccination will confer protection against subsequent exposures.

///DOWN SYNDROME
Affected individuals rarely reproduce. Between 15-30% of females with trisomy 21 are fertile and they have 50% risk of having an affected child. There is no evidence of an affected male fathering a child.

In female's About 70% are infertile, and the risk to child getting down is 50% if the mother has down syndrome,
Few facts about down syndrome,,,,
most common disease associated with down
mental retardation ,congenital heart disease,(endocardial cushion defect most common then VSD and asd, tof, pda)
leukemia, GI defect, hearing loss, cataract.

///As s3 indicate impaird ventricular compliance, so I peak s3. Though s3 is very signufican in CHF, s4 is happen to be significant in angina and MI.
this is from Merck manual.
The fourth heart sound (S4) is produced by the augmented diastolic ventricular filling near the end of diastole caused by atrial contraction
It is absent in atrial fibrillation but almost always present during active myocardial ischemia or early after MI.
The third heart sound (S3), or pericardial knock, occurs in early diastole, when the ventricle is dilated and noncompliant (hear Audio 197-8). It occurs during passive diastolic ventricular filling and indicates serious ventricular dysfunction, except in children, in whom it can be normal

/// Heparin induced thrombocytopenia.
Warfarin should be avoided in acute HIT unless it is used in combination with therapeutic-dose danaparoid, lepirudin, or argatroban. Warfarin has been associated with worsening venous thrombosis, venous limb gangrene, and/or skin necrosis when used alone or in combination with ancrod in acute HIT. However, warfarin is appropriate for longer term anticoagulation in patients with HIT and thrombosis. Warfarin should be delayed until therapeutic anticoagulation with danaparoid, lepirudin or argatroban is achieved, and ideally, until there is substantial resolution of the thrombocytopenia. Warfarin-induced thrombotic complications have been described in patients in whom the alternative anticoagulant was stopped prior to resolution of thrombocytopenia

///The risk of a diagnosis of breast cancer is slightly increased during OC use but diminishes after discontinuance and is not increased among former OC users who have discontinued OCs for >= 10 yr.
Several epidemiologic studies show that the incidence of cervical neoplasia, particularly adenocarcinoma of the cervix, is increased in OC users, particularly those who have used OCs for > 5 yr. A causal relationship has not been established, but OC users should have a Papanicolaou test at least annually.
A number of studies have shown that OC use decreases the risk of lethal endometrial and ovarian cancers by about 50%; this reduced risk persists for at least 10 to 15 yr after discontinuance. Other documented benefits of OC use include decreased incidence of abnormal uterine bleeding (including menorrhagia), dysmenorrhea, premenstrual tension, iron-deficiency anemia, benign breast disease, and functional ovarian cysts; the reduced incidence of ectopic pregnancy and of salpingitis associated with OC use should decrease infertility
If breakthrough bleeding persists, the woman should be given a combination with a higher dose of estrogen (ie, a more estrogenic formulation).

Emergency contraception (also known as the morning-after pill) is a high dosage of the birth control pill. It is recommended to be used after sexual intercourse, over a period of 72 hours, to achieve the goal of preventing or ending pregnancy. There are three different ways birth control pills are currently being promoted for this use: progesterone alone, estrogen alone, or both of these artificial steroids together. These are the same steroids found in the typical birth control pill.

Hepatitis C: the new king of chronic hepatitis (causes 2/3 of cases); usually transmitted through shared IV needles (rarely if ever transmitted sexually, donated blood now screened). Like hep B, can also progress to chronic hepatitis (roughly 75% of cases), cirrhosis, and cancer. Serology: antibody to hepatitis C virus shows evidence of prior exposure, but not immunity, as most have chronic, active infection. A test for HCV RNA detects virus directly and allows better determination of infection status / prognosis.
Most common cause of post-transfusion hepatitis (1/3300 chance).
Common in alcoholic liver dz (25-60%).
RNA: flavivirus
ELISA immunoassay test + in 2-6 wks. RIBA is confirmatory test along with PCR.

Ankle injuries are the most common injuries incurred during sports and recreational activities. They are particularly common during soccer, basketball, and volleyball.
Pathophysiology: Most ankle sprains are due to inversion during extension of the ankle. Thus, approximately 85% of injuries involve the 3 distinct lateral ligaments: anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL). Of sprains due to inversion, 65% are isolated to the ATFL. In some patients, the subtalar complex may also be injured. The CFL is rarely injured in isolation.
Isolated injury to the medial (deltoid) ligament is rare and usually involves malleolar fractures. Distal tibiofibular syndesmotic rupture is very rare and is associated with dorsiflexion and external rotation. Recovery from this injury is significantly prolonged, unlike isolated lateral ligament sprains.
Rupture of the superior peroneal retinaculum results in subluxation or dislocation of the peroneal tendons. The mechanism of injury is usually forced dorsiflexion with reflex contraction of the peroneal muscles. Patients complain of pain and a snapping sensation over the posterolateral ankle with weakness of eversion.
Ankle sprains are classified into 3 grades, as follows:
Grade I injuries involve a stretch of the ligament with microscopic but not macroscopic tearing. Generally, little swelling is present, with little or no functional loss and no joint instability.
Grade II injuries stretch the ligament with partial tearing, moderate-to-severe swelling, ecchymosis, moderate functional loss, and mild-to-moderate joint instability.
Grade III injuries involve the complete rupture of the ligament with immediate and severe swelling, ecchymosis, an inability to bear weight, and moderate-to-severe instability of the joint.
Frequency:
In the US: Inversion injuries occur at a rate of 1 per 10,000 people per day, which is about 27,000 injuries per day in the United States. Injury to the dominant ankle is 2-3 times more likely than injury to the nondominant ankle. Ankle sprains are twice as likely in intercollegiate athletes when compared with interscholastic athletes.
Mortality/Morbidity:
Ankle sprains can cause significant morbidity. As many as 73% of athletes with an ankle sprain suffer recurrent sprains, and 59% have significant disability and impairment of athletic performance.
Up to 50% of people who incur an ankle sprain have some type of chronic sequelae. These conditions include functional instability, mechanical instability, chronic pain, stiffness, and recurrent chronic swelling.
Eversion injuries are more likely to result in persistent pain or chronic instability.
Sex: Women athletes are 25% more likely to sustain ankle injuries than male athletes.
Age: Ankle injuries primarily involve young people because they participate more often in physically demanding recreational activities and sports. Fractures and tendon ruptures occur more often in older adults.

CLINICAL
History:
Assessment of all orthopedic injuries should include the following:
Mechanism of injury
Previous ankle injuries
Presence of immediate or delayed pain, swelling, and ability or inability to bear weight
Presence or absence of any popping-type sensations or actual noise at the time of injury
Physical:
Observe for edema, ecchymosis, or deformity.
Palpate for tenderness, crepitant, or deformity.
Assess active and passive range of motion as well as weight-bearing ability.
Perform talar tilt test.
Place the foot in 20-30° of plantar flexion, and apply slight adduction and gentle inversion stress to the calcaneal midfoot.
If both the anterior talofibular and the calcaneofibular ligaments are ruptured, the examiner will detect talar tilt (ie, movement of the talus in the mortise).
Perform anterior drawer test.
Place foot in 10-15° of plantar flexion and apply gentle forward traction to the heel.
With anterior talofibular ligament rupture, the deltoid ligament becomes the center of rotation, and a dimple may appear just anterior to the lateral malleolus. Forward motion of the talus is detected by the examiner.
For this test, 3 mm of movement may be significant; 1 cm of movement is certainly significant.
Perform and document a neurovascular examination, including checks of the dorsalis pedis and posterior tibial pulses.

WORKUP
Imaging Studies:
Radiographic studies of the ankle should include the following films:
An anteroposterior (AP) film with the ankle in 5-15° of adduction
A true lateral film
A 45° oblique film with the ankle in dorsiflexion (ie, Mortise view)
The Ottawa rules are a prospectively validated clinical decision tree for radiograph ordering in adults. By following these rules, emergency physicians can eliminate 30% of radiographs without missing clinically significant fractures. Criteria for foregoing radiography are as follows:
Younger than 55 years
Able to walk 4 steps at the time of injury and at the time of evaluation
No tenderness over the posterior edge (distal 6 cm) or tip of either malleolus
Other Tests:
Stress radiographs or arthrographies are not mandatory in the ED, but they may be requested by an orthopedic consultant

TREATMENT
Prehospital Care: For patient comfort, splint all ankle injuries prior to transport to the ED.
Emergency Department Care:
First-degree sprains or mild second-degree sprains
Rest, ice, and elevation
Compression dressing or commercially available air stirrup splint
Possible cessation of weight bearing initially
Early range of motion exercises
Wobble board training after recovery in order to reduce the number of recurrent injuries and prevent functional instability
Severe second- or third-degree sprains or possible fractures
Rest, ice, and elevation
Plaster or fiberglass posterior splint
Orthopedic or sports physician referral
Consultations:
Obtain orthopedic consultation for severe sprains, suspected peroneal tendon subluxation, or associated fractures.
Emergent orthopedic evaluation rarely is required. Office follow-up in a week usually suffices.

MEDICATION
The goals of therapy are to reduce pain and prevent complications.
Drug Category: Nonsteroidal anti-inflammatory drugs (NSAIDs) -- With analgesic and anti-inflammatory properties, NSAIDs are the ideal agents for treating ankle injuries. Acetaminophen with or without an opiate analgesic may be added to NSAID therapy (or used as a substitute).Drug Name
Ibuprofen (Ibuprin, Advil, Motrin) -- Usually the DOC for treatment of mild to moderate pain, if there are no contraindications.
Inhibits inflammatory reactions and pain by decreasing activity of enzyme cyclo-oxygenase, resulting in the inhibition of prostaglandin synthesis.
Adult Dose 200-400 mg PO q4-6h while symptoms persist; not to exceed 3.2 g/d
Pediatric Dose 6 months to 12 years: 20-40 mg/kg/d PO divided tid/qid
>12 years: Administer as in adults
Contraindications Documented hypersensitivity; peptic ulcer disease; recent GI bleeding or perforation; renal insufficiency; high risk of bleeding
Interactions Coadministration with aspirin increases risk of inducing serious NSAID-related side effects; probenecid may increase concentrations and, possibly, toxicity of NSAIDs; may decrease effect of hydralazine, captopril, and beta-blockers; may decrease diuretic effects of furosemide and thiazides; monitor PT closely (instruct patients to watch for signs of bleeding); may increase risk of methotrexate toxicity; phenytoin levels may be increased when administered concurrently
Pregnancy B - Usually safe but benefits must outweigh the risks.
Precautions Category D in third trimester of pregnancy; caution in congestive heart failure, hypertension, and decreased renal and hepatic function; caution in anticoagulation abnormalities or during anticoagulant therapy
Drug Name
Ketoprofen (Oruvail, Orudis, Actron) -- Used for the relief of mild to moderate pain and inflammation.
Administer small doses initially to patients with small body size, the elderly, and those with renal or liver disease.
Doses higher than 75 mg do not increase its therapeutic effects. Administer high doses with caution and closely observe patients for response.
Adult Dose 25-50 mg PO q6-8h prn; not to exceed 300 mg/d
Pediatric Dose 3 months to 12 years: 0.1–1 mg/kg PO q6-8h
