Sexual habits and clinico-etiological profile of sexually transmitted diseases in Nepal.

A total of 100 patients giving histories suggestive of sexually transmitted disease (STDs) and attending the dermatology OPD at BPKIHS (B.P. Koirala Institute of Health Sciences) in Nepal over a period of one year from 1st July 1999 to 30th June 2000 were included in this study. Out of 10,400 new dermatology cases, a total of 100 cases (0.96%) of STDs were seen. Of these 73 were males, and the majority (53%) were in the age group of 21-30 years. Most of the patients were from Sunsari district (54%). The most common profession (21%) was businessman followed by housewife (19%). The most common age for first sexual contact was 16 to 19 years (45%). Eleven percent had their first sexual contact at the age of 15 or below 15 years. Premarital sexual exposure was recorded in 17% of the unmarried males. There were only 3 homosexuals and 1 bisexual patient. Multiple contacts were recorded in 55% of the patients. The most common source of contact was a commercial sex worker in 34.15%. Condoms were always used by only 7%. The various types of sexually trasmitted diseases (STDs) were syphilis (31%) followed by condylomata acuminata (16%), herpes genitalis (15%), gonorrhoea (9%), and mixed infections (12%). Despite their varied sexual behavior, none of the patients were HIV positive; however, it is always advisable to screen all STD patients for HIV antibody.

Lichen planus after HBV vaccination in a child: a case report from Nepal.

Vaccination against hepatitis B virus has rarely been associated with lichen planus. We report a case of this kind in a child from Nepal. A 12-year-old boy had developed generalized itchy violaceous papules and plaques six weeks after the second dose of hepatitis B virus vaccine. Serum HBsAg and HBeAb were negative, but HBsAb was positive. New crops of generalized, similar eruptions developed after the booster dose of vaccine. All the lesions resolved within three months of systemic steroid therapy. There was no recurrence after one year of follow up. Awareness of such an association is necessary, especially in children, because vaccination campaigns are increasing.

Port-wine-stain (nevus flammeus), congenital Becker's nevus, café-au-lait-macule and lentigines: phakomatosis pigmentovascularis type Ia--a new combination.

A 16-year-old male had brown macules in a geographic pattern with increased terminal hair on the back and dusky red partially blanchable non progressing macules on his left thigh since birth. Clinical diagnoses of Becker's nevus and port-wine-stain were made and confirmed histopathologically. In addition, he had multiple lentigines on the face and trunk and a single café-au-lait-macule on his chest.

Oral zinc therapy in diabetic neuropathy.

The present double blind randomized study was conducted on 50 subjects; 20 age and sex matched healthy controls (Group--I); 15 patients of diabetes mellitus with neuropathy who received placebo for 6 weeks (Group--IIA); and 15 patients of diabetes mellitus with neuropathy who were given supplemental zinc sulphate (660 mg) for 6 weeks (Group--IIB). Serum zinc level, fasting blood sugar (FBS) and post prandial blood sugar (PPBS) levels and motor nerve conduction velocity (MNCV) were estimated on day 0 and after 6 weeks in all subjects. Serum zinc levels were significantly low (p < 0.001) in group IIA and IIB as compared to healthy controls (Group--I) at baseline. After 6 weeks the change in pre and post therapy values of FBS, PPBS and MNCV (median and common peroneal nerve) were highly significant (P = < 0.001) for group IIB alone with insignificant change (P = > 0.05) in group IIA. No improvement (P = > 0.05) in autonomic dysfunction was observed in either groups. Therefore, oral zinc supplementation helps in achieving better glycemic control and improvement in severity of peripheral neuropathy as assessed by MNCV.

Essential hypertension: could the basic defect be in blood supply of vasomotor centre?

Various factors have been implicated in the pathogenesis of essential hypertension, although the exact cause of essential hypertension is still unknown. In this paper it is suggested that the basic pathology in essential hypertension may be an inherited defect in the blood supply of that part of reticular formation of rostral ventrolateral medulla which contains the pressor area. The posited defect is one in which the arterial branch supplying blood to the above-mentioned pressor area of vasomotor center arises from an artery which is stenosed. The other branches of this stenosed artery supply adjacent areas of medullary reticular formation concerned with other neurological functions. Due to this stenosis there is ischaemia of the pressor area resulting in increased systemic arterial pressure. During stress, the blood requirement of adjacent areas of the reticular formation (whose function is still not clearly defined) may increase, thus further decreasing blood flow to vasopressor area and increasing the cerebral ischaemic response. After a prolonged time, this increased blood pressure can cause hyaline arteriolar nephrosclerosis in kidney, which may participate in the maintenance of elevated systemic arterial pressure.

Scrofuloderma of the scalp, psoas abscess, and caries spine: an unusual association.

An unusual association of scrofuloderma of the scalp, psoas abscess, and caries spine was seen in a 4-year-old girl. The diagnosis was confirmed by relative and absolute criteria. The peripheral T-lymphocytes and their subsets were within normal limits, although her immunohistopathological changes indicated an intermediary response across the spectrum depicting an unstable immunity. This may have been responsible for the silent spread of Mycobacterium tuberculosis and the current association.

Hypozincemia in diabetes mellitus.

The present study was conducted on 20 age and sex matched healthy controls and 30 patients of diabetes mellitus. Serum zinc levels in diabetics were found to be significantly (p < 0.001) reduced as compared to healthy controls. There was no significant sex difference (P > 0.05) in serum zinc levels amongst diabetic patients and healthy controls. Hypozincema in diabetes mellitus may be due to altered zinc metabolism and oral zinc may have a role in therapy.

Is combined therapy of sympathomimetics and theophylline indicated?

Bronchodilator effect and toxicity of theophylline 300 mg twice a day (R1), salbutamol 4 mg tid (R2), their combination in higher (200/4mg, R3), and lower doses (100/2mg R4), and placebo (calcium lactate 300 mg) tid (R5) were compared in 25 patients with bronchial asthma in a randomized crossover trial. Statistically significant improvement in forced expiratory volume in one second (FEV1) was observed in all the active treatment groups (R1 to R4) compared with placebo (R5). The mean improvement in FEV1 was 29.0%, 22.0%, 28.0%, 30.0%, and 0.73% in regimen R1, R2, R3, R4, and R5, respectively day 1, and corresponding improvement was 30.0%, 24.0%, 29.0%, 34.0%, and 4.4% on completion of one week therapy. On intergroup statistical comparison, mean improvement in pulmonary function test values were statistically significant or highly significant in regimens R1 to R4, as compared with placebo. However, improvement between any two regimens was not statistically significant in any of the regimens (R1-R4). Almost all the regimens were tolerated well and no patient showed major adverse reactions or cardiotoxicity necessitating withdrawal of the drug. On the other hand, minor adverse reactions were common and the high dose combination (R3) was found to have more adverse reactions than the low dose combination and either drug used alone.
