Fine-needle aspiration diagnosis of carotid body tumor: report of a case and review of experience with cytologic features in four cases.

A 45-yr-old female presented with a left upper cervical swelling of 4 yr duration. The clinical suspicion of carotid body tumor (CBT) was confirmed by imaging findings, fine-needle aspiration (FNA) cytology, and histology of the resected tumor. Review of our experience with four cases including the present one during 10 yr (1984-1994) showed that the age of the patients ranged from 35 to 45 yr with a mean of 40.

Fine needle aspiration cytologic appearance of inflammatory pseudotumor of the liver. A case report.

Background: Inflammatory pseudotumor (IPT) is a rare space-occupying lesion of the liver that can be clinically confused with a malignant process.

Case Report: A 28-year-old male presented with fever and a palpable, firm liver. Ultrasonography and computed tomography revealed a mass in the right lobe of the liver.

Contrast echocardiography displays increased subendocardial perfusion after nitroglycerin administration.

A mechanism proposed to contribute to the antianginal effect of nitroglycerin is a redistribution of coronary blood flow to the subendocardium. Contrast echocardiography combines ultrasound with echogenic contrast agents to assess regional myocardial perfusion. This study aims to assess the effect of nitroglycerin on myocardial transmural perfusion with contrast echocardiography in humans.

Acute renal failure in the elderly: a demographic and clinical study of patients in eastern India.

A total of 638 patients with acute renal failure (ARF) of diverse etiology were studied over a period of 9 years (July 1985-Dec, 1994) of which 96 (15%) patients were classified as elderly ARF with mean age of 72.5 years. Medical causes accounted for 80% of geriatric ARF while 20% patients, had ARF of surgical origin.

Nucleolar organiser regions in different colonic epithelia.

The argyrophilic technique (AgNOR) was applied to paraffin sections of 10 acute self-limited colitis, 15 ulcerative colitis (UC), 5 ulcerative colitis with indefinite dysplastic change, 10 adenomatous polyps, 20 colorectal adenocarcinomas and 10 normal colorectal mucosa. The mean number of nucleolar organiser regions (NORs) per nucleus ranged between 1.62-2.

HTLV-I in HIV seropositive Indian blood donors.

One hundred HIV seropositive blood donors were screened for the presence of antibodies to HTLV-I by passive agglutination test from 1994 to 1996. Thirty two percent of the HIV-I seropositive blood donors were found to be positive for HTLV-I (Titre 1:16). Only Six percent of the HIV-seronegative donors were found to be positive for HTLV-I indicating thereby that it should be mandatory to screen all the blood samples for transfusion for HTLV-I antibodies also.

Acute renal failure in falciparum malaria--increasing prevalence in some areas of India--a need for awareness.

Twenty-six cases (4.8%) from a total of 540 patients with acute renal failure (ARF) of diverse aetiology had ARF in association with falciparum malaria. Their ages ranged from 15 to 85 years (mean 31.

Diagnosis and outcome of isolated rectal tuberculosis.

Purpose: Segmental colonic tuberculosis commonly involves the ascending, transverse, or sigmoid colon. Rectal involvement in tuberculosis is uncommon and poorly characterized. This study describes the clinical presentation, endoscopic features, and outcome of isolated rectal tuberculosis.

Endoscopic techniques in the diagnosis of upper gastrointestinal tract malignancies. A comparison.

Objective: To perform a comparative evaluation of various endoscopic techniques in the diagnosis of upper gastrointestinal tract malignancies.

Study Design: Thirty cases of suspected malignancy involving the upper gastrointestinal tract were studied. In all 30 cases, four endoscopic cytology techniques (brushing before biopsy, brushing after biopsy, fine needle aspiration cytology [FNAC] and suction cytology) were evaluated and correlated with histology by forceps biopsy.

Membrane fusion in organelle biogenesis.

Intracellular membrane fusion is a fascinating reaction that is crucial for cellular function. Several components of the membrane fusion machinery have been identified, although a precise understanding of the fusion mechanism is lacking. More recent studies are revealing novel proteins that regulate membrane fusion during organelle assembly.

Loss of contrast intensity during systole in the left ventricular cavity with the use of the contrast agent Albunex. An analysis of its correlation with pressure and velocity.

Rationale And Objectives: Several investigators have observed a decrease in video intensity in the left ventricular cavity during systole when using contrast echocardiography. It has been suggested that this phenomenon is related to microbubble instability. The authors propose that this phenomenon is, in part, related to the effects of pressure and velocity on the acoustic reflectance of ultrasound contrast agents.

Efficacy of low-dose alpha interferon therapy in HBV-related chronic liver disease in Asian Indians: a randomized controlled trial.

Background/aims: Interferon therapy has been shown to be effective in Western patients with chronic hepatitis due to hepatitis B viral infection, but not in Asian Chinese. Its efficacy in Asian Indian subjects with chronic HBV infection is not known.

Methods: Forty-one patients with HBV-related chronic liver disease received randomly either: (a) recombinant alpha 2b interferon (n = 20) 3 MIU, subcutaneously, three times a week for 4 months, or (b) no treatment (n = 21).

Acute renal failure in eastern India.

The present study included 426 patients with acute renal failure age range 7 months to 85 years, during 8-year period (1984-1992). Medical, surgical and obstetric causes were responsible for ARF in 68.3, 17.

Granulomatous hepatitis: a retrospective study.

51 cases of granulomatous hepatitis were seen among 1234 liver biopsies over a 10 year period. Tuberculosis was the commonest cause seen in 55 percent of cases. Other causes included leprosy, sarcoidosis, histoplasmosis, brucellosis, amoebic liver abscess, lymphoma and malignant granuloma.

Intestinal metaplasia--its association with gastric cancer.

Endoscopic gastric biopsies from 230 patients and post gastrectomy specimens of 18 patients were evaluated for the presence of intestinal metaplasia (IM) and its association with the gastric lesions. There were a total of 78 malignant and 170 benign lesions. IM was present in 53% of patients with gastric carcinoma (GC) and in 10.

The formation of Golgi stacks from vesiculated Golgi membranes requires two distinct fusion events.

We have reconstituted the fusion and assembly of vesiculated Golgi membranes (VGMs) into functionally active stacks of cisternae. A kinetic analysis of this assembly process revealed that highly dispersed VGMs of 60-90 nm diameter first fuse to form larger vesicles of 200-300 nm diameter that are clustered together. These vesicles then fuse to form tubular elements and short cisternae, which finally assemble into stacks of cisternae.

Spectrum of gastrointestinal malignancy over a period of 10 years at a tertiary referal center of India.

We studied the frequency of different gastro intestinal malignancies (GIM) diagnosed in a given year, among patients attending gastroenterology department, and changing pattern of their occurrence over a period of 10 years (1984-1993). The records of all patients with histologically confirmed GIM were screened. Out of 83380 outdoor patients registered in the department over 10 years, there were a total of 1751 (2.
