Congenital infection is considered to have occurred if the infant has IgM antibodies sholy after bih.( as IgM antibodies do not cross placenta,their presence indicate they must have been synthesised by the infant inutero) or if IgG antibodies persist for more than 6 months. At bih virus is easily detected in pharyngeal secretion,multiple organs, CSF ,urine and rectal swabs. Rubella infection inhibits cell division.

B: P.falciparum In well-stained preparations the nuclei of the parasites are always stained red and the cytoplasm blue. The presence of malaria pigment is very characteristic of the older stages of Plasmodium sp. P. falciparum often contains a single black dot. P. vivax often contains countless fine golden yellow/brown specks of malaria pigment. In P. ovale and P. malariae the pigment inclusions are many and brownish black. Countless fine red spots in the red blood cell (Schiiffner's dots) can be seen in P. vivax and P. ovale (the more mature the parasite, the more dots). In P. ovale the dots are sometimes called James's dots. Sometimes a few flecks can be observed in P. falciparum (Maurer's dots or clefts). P. malariae almost never exhibits dots (Ziemann's dots). The visibility of these dots depends to a great extent on the acidity (pH) with which the thin slide preparation is stained (slightly alkaline: pH = 8 is best).

High dose methotrexate\nB. Cyclophosphamide\nC. Vincristine\nD. Doxorubicin\n", "role": "user" }, { "content": "###Rationale: Methotrexate (Mtx): It is one of the oldest and highly efficacious antineoplastic drugs; inhibits dihydrofolate reductase (DHFRase)-blocking the conversion of dihydrofolic acid (DHFA) to tetrahydrofolic acid (THFA) which is an essential coenzyme required for one carbon transfer reactions in de novo purine synthesis and amino acid interconversions. The inhibition is pseudoirreversible because Mtx has 50,000 times higher affinity for the enzyme than the normal substrate. Methotrexate is apparently curative in choriocarcinoma: 15-30 mg/ day for 5 days orally or 2G-40 mg/m2 BSA i.m. or i.v. twice weekly. It is highly effective in maintaining remission in children with acute leukaemias, but not good for inducing remission: 2.5-15 mg/day. It is also useful in other malignancies, rheumatoid ahritis, psoriasis and as immunosuppressant.The use of folinic acid rescue has permitted much higher doses of Mtx and has enlarged its scope to many difficult-to-treat neoplasms. USES: 1)NEOPLASMS 2)MENINGEAL LEUKEMIA 3)OSTEOSARCOMA 4)RHEUMATOID AHRITIS 5)PSORIASIS 6)BREAST CANCER 7)HEAD AND NECK CANCER 8)MYCOSIS FUNGOIDES Cyclophosphamide: It is inactive as such: produces few acute effects and is not locally damaging. Transformation into active metabolites (aldophosphamide, phosphoramidemustard) occurs in the liver, and a wide range of anti tumour actions is exeed. It has prominent immunosuppressant propey. Thus, it is one of the most popular anticancer drugs. It is less damaging to platelets, but alopecia and cystitis (due to another metabolite acrolein) are prominent. Chloramphenicol retards the metabolism of cyclophosphamide.

It has become a highly accurate test, often obviating the need for carotid arteriography prior to carotid endarterectomy. Carotid arteriography remains the \"gold standard\" when quantifying the degree of carotid stenosis, but it is usually performed after noninvasive testing suggests significant stenosis. Spiral CT angiography is a new noninvasive modality that has been used to evaluate many segments of the vascular tree, but as yet its accuracy does not approach that of standard arteriography and it would certainly not be used in the initial evaluation of a patient with an asymptomatic bruit. Magnetic resonance arteriography (MRA) is also a relatively new modality that has enjoyed moderate success in the investigation of carotid disease. Although not quite as accurate as standard arteriography, it has been used in conjunction with the duplex as a complementary study.

The differential diagnosis for ST-segment elevation includes, among other things, acute myocardial infarction, pericarditis, and left ventricular aneurysm. In this case, the upward concavity of the ST segment, the PR-segment depression, the lack of Q waves, and the diffuse nature of the ST-segment elevation in more than one coronary artery distribution make pericarditis the likely etiology.
