Entrance exam oriented Focus-
1)A new point in the 18th edition -TTP in pregnancy has been framed in AIPG-2012 exam.
2)The other new point regarding Ehlers-Danlos syndrome in pregnancy is a potential one for the upcoming examinations!

* Carpal tunnel syndrome. (median n)
* Meralgia paresthetica (lat. femoral cutaneous nerve)-AI-2007***
* Carpal Tunnel – pain worse in night
*Restless leg syndrome is the most common peripheral nerve and movement disorder in pregnancy. Disordered iron metabolism is the probable etiology. (18th EDITION)
*Maternal death is defined as the death occurring during pregnancy or within 42 days of completion of the pregnancy from a cause related to or aggravated by the pregnancy, but not from accident or incidental causes (18th EDITION)
Neoplasia During Pregnancy( a new chapter in 18th edition-all points given below are from 18th edition))
*The four cancers most commonly developing during pregnancy are
• cervical cancer
• breast cancer
• melanoma
• lymphomas (particularly Hodgkin's )
*Cervical intraepithelial neoplasia has a low risk of progression to invasive cancer during pregnancy (0.4%) and many such lesions (36–70%) regress spontaneously postpartum
*Cone biopsy should not be done within 4 weeks of delivery.
*If the disease is microinvasive, vaginal delivery can take place and be followed by definitive treatment, usually conization.
* If a lesion is visible on the cervix, delivery is best done by caesarian section and followed by radical hysterectomy.
2)Pregnancy-associated breast cancer
*Defined as cancer detected during the pregnancy and up to 1 year after delivery
*45% in the second trimester
*70% of the breast cancers found in pregnancy are estrogen receptor–negative
*Pregnancy retains its protective effects in carriers of BRCA1 mutations
*pregnancy seems to increase the risk of breast cancer among carriers of BRCA2 mutations
*28–58% of the tumors express HER-2
*Even in pregnancy, most breast masses are benign (80% are adenoma, lobular hyperplasia, milk retention cyst, fibrocystic disease, fibroadenoma)
*Lumpectomy followed by adjuvant chemotherapy is frequently used; fluorouracil and cyclophosphamide with either doxorubicin or epirubicin have been given without major risk to the fetus
*Methotrexate and other folate antagonists are to be avoided
*Trastuzumab are unsafe during pregnancy
*Estrogen increases 100-fold; progesterone increases 1000-fold during pregnancy
3)Melanoma During Pregnancy
* melanoma is not more aggressive during pregnancy
*ipilumimab (antibody to CTLA-4), and in those with BRAF mutation V600E, a BRAF kinase inhibitor
4)Hodgkin's Disease and Non-Hodgkin's Lymphoma
*May be accompanied by B symptoms (fever, night sweats, unexplained weight loss).
*Women diagnosed in the second and third trimester can be treated safely with combination chemotherapy, usually doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD).
*If symptoms requiring treatment appear during the first trimester, evidence suggests that Hodgkin's disease symptoms can be controlled with weekly low-dose vinblastine
*Non-Hodgkin's lymphomas are more unusual in pregnancy but are usually aggressive
5) Thyroid Cancer During Pregnancy
*Patients with follicular cancer or early papillary cancer can be observed until the postpartum period
*Patient on Radioactive iodine should not become pregnant for 6–12 months after treatment.
*Demand for thyroid hormone increases during pregnancy, and doses to maintain normal function may increase by 30–50%-Total T4 levels are higher during pregnancy
*The target TSH level is lower than 2.5 mIU/L.
6) Gestational Trophoblastic Disease
*Moles are the most common
* A previous molar pregnancy makes choriocarcinoma about 1000 times more likely to occur
*Partial moles result from fertilization of an egg by two sperm, resulting in diandric triploidy.*** (???AIIMS NOV-2013)
* Complete moles usually have a 46,XX genotype;
*95% develop by a single male sperm fertilizing an empty egg and undergoing gene duplication (diandric diploidy);
* 5% develop from dispermic fertilization of an empty egg (diandric dispermy)

Dukes Criteria

The Duke Criteria for Infective Endocarditis requires that a certain minimum criteria be present.
Infective endocarditis can be diagnosed based upon any of the following:
1. Two major criteria being met OR
2. One major and three minor criteria being met OR
3. Five minor criteria being met
Major criteria:
A. Positive blood culture for Infective Endocarditis (IE)
Typical microorganism that can cause IE from 2 separate blood cultures [Typical organisms include Streptococcus viridans, Streptococcus bovis, Haemophilus (parainfluenzae, aphrophilus, paraphrophilus), Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, Kingella kingae), OR Community acquired Staphylococcus aureus or enterococci, in the absence of a primary focus OR Microorganisms consistent with IE from "persistently positive" blood cultures meeting criteria of: 2 positive cultures with blood samples drawn >12 hours apart OR 3 of 3 or 3 of 4 separate blood cultures being positive (with first and last sample drawn 1 hour apart)
B. Evidence of endocardial involvement with either:
Positive echocardiogram for IE (with at least one of the items below) oscillating intracardiac mass on valve or supporting structures, in the path of regurgitant jets, or on implanted material in the absence of an alternative anatomic explanation OR Abscess OR New partial dehiscence of prosthetic valve New valvular regurgitation (worsening or changing of preexisting murmur not sufficient)
Minor criteria:
A. Predisposition to IE (Predisposing heart condition or intravenous drug use)
B. Fever (T> 38.0°C or >100.4°F)
C. Vascular phenomena [Major arterial emboli, septic pulmonary infarcts, mycotic aneurysm, intracranial hemorrhage, conjunctival hemorrhages, or Janeway lesions (non-tender, small erythematous or haemorrhagic macules or nodules in the palms or soles)]
D. Immunologic phenomena [Glomerulonephritis, Osler's nodes (small papule that is tender on the palmar finger pads or plantar toes), Roth's spots (Retinal hemorrhages with white or pale centers) and positive rheumatoid factor testing]
E. Microbiological evidence [Positive blood culture that does not meet a major criterion as noted above (however a single blood culture for coagulase negative staphylococci, diphtheroids or organisms that do not usually cause endocarditis does not count for this criteria) or serological evidence of active infection with an organism that is consistent with IE
F. Echocardiographic findings that are consistent with IE but do not meet the major criteria echocardiographically

Vaccine and strains-










1. Cholecalciferol = Vit D3 = Calciol

Causes profound hypocapnia
Seen in profound metabolic acidosis, i.e. diabetic
Groups of irregular breathing with periods of apnea that occurs at irregular intervals
General a reflection of lesions in the low pons or upper medulla
Differs from cheyne-Stokes pattern because there is no increasing and decreasing depth of

Exhibits very deep and rapid respirations
Usually seen with lesions of the midbrain and upper pons
Respirations are generally regular and the PACO2
