The Indian Contraceptive Testing Unit started making field trials with oral contraceptives in 1964. By June 1968, 958 women were taking oral contraceptives. Combination tablets used contained a minimum amount of progestogen (.5-3 mg) and a suitable amount of estrogen. The 21-tablet pack was found mot suitable. It was found that if a woman missed taking the tablets in the latter half of the cycle usually no harm resulted, but if she missed them at the beginning of the cycle pregnancy might follow as ovulation would not be inhibited. Main contraindications are liver damage, toxic hyperthyroidism, thromboembolic disease, and cancer of the genital tract or breast. Caution is advised for persons with chronic nephritis, a history of eclampsia, hypertension, varicose veins, ophthalmological disorders, or psychic depressive states. Side effects have been less with the smaller doses. The most serious side effect is thromboembolism. Those reported have been leg pain, giddiness, headache, breakthrough bleeding, nausea, vomiting, amenorrhea, abdominal pain, weakness, increased blood pressure, and skin rashes. Others have reported ocular disease and cranial nerve palsy. Sequential therapy has been reported to have a lower incidence of side effects but a higher rate of pregnancy. Low-dose progestogen therapy, the "minipill," does not inhibit ovulation but is effective by causing changes in the endometrium and in the mucus. The chlormadinone in the minipill does not affect lactation. However, the incidence of pregnancy is similar to that with an IUD (Lippes loop) which is 2.6/100 cases. Laboratory tests have been normal, except an increase in the thymol turbidity test. Vaginal cytology has revealed no case of malignancy. Results show that oral contraceptives are suitable for use on a mass scale as a method of population control.

The present study was conducted among 719 patients enrolled by 109 doctors to evaluate the efficacy and tolerability of the combination of losartan potassium and amlodipine besylate in Indian patients with mild to moderate hypertension. Out of them 11 patients were dropped out. Of these 708 patients 643 patients received once daily dosage of the combination whereas 10 patients received 1/2 daily, 13 patients received 1 1/2 daily and 42 patients received 1 twice daily dosage of the combination. The mean SBP in the study was 172.89 +/- 19.18 mm Hg baseline. After the 10-day treatment, the mean SBP had significant reduction ie, 13.1% from basal and at the end of day 20 of the treatment, the reduction was 19.13% from the baseline which was significant. Similarly mean DBP was 105.42 +/- 10.85 mm Hg at baseline. After treatment, the mean DBP had significant reduction. After 10- day treatment, there was 12.7% reduction from the baseline and at the end of the treatment ie, after day 20, the reduction was 17.70% from basal, which was significant. Global evaluation of efficacy was done by the physicians; 93.8% of the cases had excellent to good response and 4.9% patients had fair response. Details of any adverse event reported or noted during the treatment with the combination were recorded in the appropriate section of the case record form, whether considered treatment related or not, as reported by the patients. The severity of an adverse event was graded on a 3-point scale as mild, moderate and severe. The most common side-effects reported were oedema of feet (5.08%), ankle oedema (1.98%). Remaining adverse events included some cardiovascular events such as palpitations, gastro-intestinal events such as constipation, miscellaneous events, muscular pain, weakness, generalised swelling, etc. CNS events included giddiness, headache, insomnia, etc.

There was an outbreak of new emergence viral encephalitis caused by Nipah virus among humans in some areas of Bangladesh during 2001 - till to date. The disease affected mainly the young, had increased suspicion to spread from bat to man through eating of the same fruits. The risk of human-to-human transmission is thought to be low though many of the affected individuals belonged to the same family. The disease presented mainly as acute encephalitis with usually a short incubation period of less than two weeks, with the main symptoms of fever, headache, and giddiness followed by coma. Distinctive clinical signs include areflexia, hypotonia, hypertension, tachycardia and segmental myoclonus. Serology was helpful in confirming the diagnosis. Magnetic resonance imaging (MRI) showed distinctive changes of multiple, discrete or confluent small high signal lesions, best seen with fluid-attenuated inversion recovery (FLAIR) sequences. Mortality was as high as 32-92% and death was probably due to severe brainstem involvement. Relapse encephalitis was seen in those who recovered from acute encephalitis, and late-onset encephalitis was seen in those with initial non-encephalitic or asymptomatic diseases. Both these manifested as focal encephalitis arising from recurrent infection.

Coarctation of aorta is a common congenital heart defect. The diagnosis may be missed unless a highindex of suspicion is maintained, and is often delayed until the patient develops congestive heart failure (CHF), (common in infants) or hypertension (common in older children). It seldom goes undiagnosed till adulthood and frequently leads to complications as a result of long-standing high blood pressure. Intracranial haemorrhage, premature coronary artery disease, aortic aneurysms and rupture have all been reported. But it is rare to see a patient with preductal (infantile) coarctation survive childhood and presents with an infarct in adulthood. We herein present a case report of a young woman who came with vomiting and giddiness and was diagnosed as a case of cerebellar infarct due to a concealed preductal (infantile) coarctation of aorta.
