HIV entered and began to spread throughout India approximately one decade later than it did in the US, Canada, Europe, other developed countries, Africa, and the Caribbean. Accordingly, the AIDS epidemic in India continues to evolve, with the spread of HIV infection in many parts of India already reaching epidemic proportions. The long incubation period between HIV infection and the onset of AIDS, however, means that the majority of infected adults will come down with AIDS in the mid-1990s. AIDS in India will have significant adverse economic effects upon the country. Once ill with opportunistic infections as a result of HIV infection, people will require treatment. The costs of such treatment will strain resources. High levels of AIDS morbidity and mortality among individuals in their most productive years will also reduce the overall productive contributions of society to economic development. The extent of the HIV/AIDS problem in India needs to be accurately assessed, then followed by the implementation of appropriate prevention and care programs. The situation will not be able to reversed if responsible parties act only after the existence of HIV/AIDS becomes evident in large numbers of people. Policymakers and program planners working against the spread of HIV throughout India will be called upon to strike and maintain a balance in the allocation of resources for treatment and prevention. They will have to be realistic, yet humanistic, while considering individual rights in the context of more broad social welfare. The authors explain that it is cheaper to prevent AIDS than to treat and manage it, and that urgent measures are needed to protect the productive base of the economy. Sections discuss the role of epidemiology, the spread of HIV through infected needles and syringes, AIDS and HIV in Maharashtra, and the economics of AIDS.

In this single-blind, multiple-dose study the efficacy and tolerability of flurbiprofen was compared with that of piroxicam in 60 adult patients suffering from osteoarthritis of the knee. The patients were randomly allocated to receive either flurbiprofen 100 mg twice daily or piroxicam 20 mg once daily for a period of four weeks. Clinical assessments w.r.t. pain, tenderness, stiffness, swelling and general activity of patient were carried out prior to initiation of trial therapy and thereafter at weekly intervals for four weeks. The findings were graded. Though significant improvements as compared to baseline data occurred in both the treatment groups, flurbiprofen was found to be superior to piroxicam in improving pain on movement and at rest (p < 0.05). The incidence of side effects was less in the group receiving flurbiprofen (6% compared to 47% observed with piroxicam).

Study of intrarenal vasculature was carried out by using the metallic impregnation technique on whole kidney sections in 31 [corrected] cases of (primary and secondary) hypertension and 10 normal controls. Distinct patterns of intrarenal vasculature were noted in controls and in cases of hypertension. Gradual tapering of vessels, absence of tortuosity and good peripheral vascularisation were noted in controls. Abrupt tapering, tortuosity of vessels and poor peripheral vascularisation were noted in hypertensive cases. In essential hypertension moderate to severe changes of dilatation of the segmental and/or arcuate arteries was noted. The degree of dilatation was related to the level of systolic BP rather than diastolic in cases of essential hypertension. Secondary hypertension even if severe, rarely showed significant dilatation lesions. Avascular zones and conglomeration of vessels at poles was seen only in cases of pyelonephritis. This helped in distinguishing these, from cases of glomerulonephritis.

Patients with pericardial constriction show a prominent 'y' descent in right atrial and vena caval pressure traces. In all earlier hemodynamic descriptions of constrictive pericarditis, the 'y' descent has been described as 'brisk', 'sharp' or 'rapid' but no effort has been made to quantify the same. In this study, we have tried to objectively evaluate and describe this 'y' descent by measuring its negative slope (-dy/dt) at its steepest portion. Forty one patients were studied hemodynamically, 9 with constrictive pericarditis (Group I) and 32 normals (Group II). The negative slope of the 'y' descent in patients with constrictive pericarditis (69.95 +/- 23.04 mm Hg) was found to be significantly greater than normals (35.13 +/- 7.84 mm Hg, p < 10(-6). Discriminant analysis was used to determine its sensitivity, specificity, predictive value and overall accuracy, in the diagnosis of pericardial constriction. Value of > or = 45 mm Hg/sec was found to have the highest overall accuracy (0.88). The correlation between the right ventricular end diastolic pressure and the slope of 'y' descent in patients with pericardial constriction (r = 0.66) and in normals (r = 0.60) was fair. It is concluded that -dy/dt is significantly different in patients with constrictive pericarditis as compared to normals. The diagnostic utility of this parameter needs to be evaluated in patients with equivocal clinical and hemodynamic data, in those with occult pericardial constriction and in post-pericardiectomy cases where the pressures do not normalise immediately after adequate pericardial resection.

Benign neoplasms are curable only when excised. This applies even to craniopharyngiomas. The proximity of craniopharyngiomas to the hypothalamus and neurovascular structures makes total excision difficult to achieve. Over the last 3-4 decades, it has become increasingly obvious that craniopharyngiomas respond to radiation therapy. Early, unhappy results with major excisions have prompted us to adopt a policy of conservative surgery and radiation therapy to the residual tumour. Preliminary results suggest a good outcome in 35 of the 63 patients so treated from 1981. Details of the study are presented.

Wildervanck syndrome i.e. cervico (Klippel-Feil anomalad) -oculo (Duane-Stilling-Turk phenomenon with bilateral abducens palsy)-acoustic (deafness) is a rare syndrome. We report here 4 cases diagnosed as Wildervanck syndrome and analyse their findings. One patient had an an atrial septal defect. Such association of congenital heart disease with Wildervanck syndrome has not been reported previously.

We present a study of fibrinogen levels in 133 patients who were prone to develop disseminated intravascular coagulation as a result of an underlying complication of pregnancy such as abruptio placentae, pregnancy-induced hypertension, missed abortion, septic abortion, intrauterine fetal death, vesicular mole and amniotic fluid embolism. A high incidence of hypofibrinogenemia was found in cases of abruptio placentae (43.9%) and pregnancy-induced hypertension (25%). Hypofibrinogenemia occurred in 10% cases of intrauterine fetal death within 4 weeks of fetal demise. The use of this simple investigation makes possible the diagnosis of hemostatic failure and also helps to guide replacement therapy during the fibrinopenic state. There were 4 maternal deaths and 12 perinatal losses in this study.

A case of hydatid cyst of the tibia, which manifested as a pathologic fracture is being reported. Pain and swelling of left lower limb with inability to bear the weight were the main features. Tender swelling was also noted at the upper and middle third of tibia. Open biopsy revealed the hydatid cyst wall and scolices of Echinococcus granulosus. Albendazole treatment was followed by curettage and bone grafting.

A forty year old male patient presented with swollen, deformed right hand with multiple irregular ulcers. The axillary lymph nodes were enlarged, firm and tender. The biopsy of nodules present on the hand revealed areas of haemorrhage and necrosis. The histopathological examination confirmed the clinical diagnosis of epithelioid sarcoma. Following below-elbow amputation, patient failed to regain consciousness and expired. On autopsy, distant metastases were found in the regional lymph nodes, pleura, kidney and cerebrum.

A case of rheumatic heart disease (RHD) with prosthetic mitral valve endocarditis receiving anticoagulation with heparin, underwent medical termination of pregnancy in a second trimester. The following report entails the use of aminocaproic acid (ACA) in preventing excessive bleeding during and after the procedure, while the patient continued to receive anticoagulant therapy.

Orbital cysticercosis is a rare condition. We report here 3 cases with orbital cysticercosis who presented with proptosis and ptosis (Case no. 1 and 2) and focal seizures (Case no. 3). All of them had a vision of 6/6. Diagnosis of cysticercosis was made on CT Scan. The lesions isolated in Cases 1 and 2 and were excised. Drug therapy was given to treat any persisting infestation. Case no 3 had multiple brain cysticerci in addition to the orbital one. However, the patient was lost to follow-up.

This paper describes a young man who was treated with amputation for osteogenic sarcoma of the lower end of the right tibia. Pre-operative whole body bone scan with 99 mTc did not reveal abnormal tracer concentration in the lungs. A similar follow-up bone scan six months post-operatively demonstrated an area of abnormal tracer concentration in the lower lobe of each lung.

A case of insulinoma who had episoic bizarre behaviour is presented here. Pre-operative fasting and two hour post-prandial blood sugar values indicated hypoglycemia with inappropriately high insulin levels. USG and CT scan of the abdomen revealed a tumor of head of the pancreas. The tumour was enucleated surgically. Histopathological examination confirmed the origin as islet cells. The post-operative blood sugar and insulin levels were found to be in normal range. Since insulinoma is a rare pancreatic tumor, differential diagnoses along with a brief review of the literature is also presented.

A 25 yr old married woman with complaints of lower abdominal pain for 2 months, was found to have a irregular nontender mass in pelvis, adherent to uterus. Her Papanicolaou smear was inflammatory. To confirm the diagnosis of either ovarian malignancy or pelvic tuberculosis made on the basis of observations during exploratory laparotomy, ovarian biopsy was taken. The imprint cytodiagnosis was tuberculosis. The patient was then managed surgically and the previous diagnosis was reconfirmed by histopathology. Imprint cytodiagnosis appears to be a valuable technique whenever facilities for frozen section are not available.

A case of multiple chylous cysts of the abdomen in a 35 years old female is presented here. The patient presented with signs and symptoms of acute intestinal obstruction. Exploratory laparotomy revealed few intestinal adhesions along with multiple small cysts containing blood stained gelatinous material in the abdominal cavity, some of which were excised alongwith lymph nodes. The abdomen was closed after a saline peritoneal lavage. Chylous nature of the cysts was confirmed on histopathology. The post-operative course was asymptomatic.

A full term female baby at birth showed the features of Fraser's syndrome viz. upper lid coloboma, cryptophthalmos, abnormal groove over temporal region, dysmorphic facies, hypospadias and bilateral syndactyly. On ultrasound examination of the abdomen and left orbit, maldeveloped kidney and eyeball were found. Other siblings were not affected. The child died at the age of 3 months.

Extrapancreatic gastrinoma is a rare clinical entity encountered in surgical practice. A patient was referred to us who had a history of recurring symptoms of peptic ulcer disease and ulcer perforation located at an unusual site. Serum gastrin levels were abnormally high. Scopy revealed multiple ulcers in the antrum and duodenum. A mass superior to the head of the pancreas was detected on USG, which later on found to be a separate mass on CT scan. The tumour was excised and confirmed on histopathology. Results of conservative surgery were found to be satisfactory.
