The American Urological Association Symptom Index for Benign Prostatic Hyperplasia.

A symptom index for benign prostatic hyperplasia (BPH) was developed and validated by a multidisciplinary measurement committee of the American Urological Association (AUA). Validation studies were conducted involving a total of 210 BPH patients and 108 control subjects. The final AUA symptom index includes 7 questions covering frequency, nocturia, weak urinary stream, hesitancy, intermittence, incomplete emptying and urgency. On revalidation, the index was internally consistent (Cronbach's α = 0.86) and the score generated had excellent test-retest reliability (r = 0.92). Scores were highly correlated with subjects' global ratings of the magnitude of their urinary problem (r = 0.65 to 0.72) and powerfully discriminated between BPH and control subjects (receiver operating characteristic area 0.85). Finally, the index was sensitive to change, with preoperative scores decreasing from a mean of 17.6 to 7.1 by 4 weeks after prostatectomy (p <0.001). The AUA symptom index is clinically sensible, reliable, valid and responsive. It is practical for use in practice and for inclusion in research protocols.

Studies on the changes in lipid peroxidation and antioxidants in drought stress induced cowpea (Vigna unguiculata L.) varieties.

Cowpea (Vigna unguiculata L.) is one of the major vegetable crops cultivated in tropical conditions. Two varieties of cowpea, i.e., Vigna unguiculata L.cv Kanakamony and cv Pusakomal were selected for the present study. The changes in lipid peroxidation, ascorbic acid content and activities of enzymatic antioxidants associated with drought stress were determined. A high level of lipid peroxidation was observed in test plants subjected to water stress. The Pusakomal leaves with severe stress showed 2.7 fold increase in TBARS compared to control and 1.2 fold to that of Kanakamony The drought tolerant variety showed significant increase in the activities of peroxidase and catalase on exposure to drought stress. Kanakamony leaves in severe stress possess 1.09 times increase in peroxidase and 1.8 times increase in catalase activity than Pusakomal. The concentration of ascorbic acid in test plants depleted with increased drought stress in both varieties. While the leaves of tolerant variety in severe stress showed 1.13 times higher ascorbic acid content than Pusakomal. Among the two varieties, Kanakamony possess the best antioxidant system to tolerate drought stress. This could limit cellular damage caused by active oxygen species, during waterdeficit. The variety Pusakomal was relatively poor in these adaptations.

Antibacterial effects of Coscinium fenestratum.

Antibacterial activity of Coscinium fenestratum is mainly due to the presence of berberine.

Antimicrobial properties of ixora coccinea L. (Rubiaceae).

Antimicrobial activity was detected in the 50% ethanolic extract of Ixora coccinea. The effective inhibitory concentration of the extract against both the bacterial test organisms and the fungal test organisms studied was 125 ug mL(-1), beyond which the inhibitory activity declined and the organisms started reviving from the effect of the antimicrobial principle.

Eosinophilic enteritis with perforation.

A case of eosinophilic granuloma of the gastrointestinal tract with free perforation is described. The authors believe this is the first such case to be published. The patient, a 60-year-old woman, had no history of allergy. At laparotomy, 100 ml of pus was aspirated. A 42-cm section of small bowel, containing multiple punched-out ulcers, was excised. The mucosa and submucosa of the operative specimen were edematous; there was a moderate inflammatory infiltrate containing numerous eosinophils and neutrophils. The lesion appeared to represent a local reaction to some antigen with resultant eosinophilic infiltration.

Fungal mastitis. Case report.

Fungal (cryptococcal) mastitis in a young woman seemed to be a systemic manifestation of the infection, since it recurred contralaterally within 4 months. Diagnostic problems are discussed. Only two previous reports of deep mammary mycosis were found. In addition to excision, ketoconazole is recommended to prevent recurrence or serious complications.

Gall-bladder interposition: a rare anomaly of the extrahepatic ducts.

Abnormalities in bile ducts pattern occur frequently enough to merit importance during cholecystectomy. A patient with anomalous insertion of both hepatic ducts into the gall-bladder with the cystic duct replacing the common bile duct is described. This case, and related anomalies of the bile ducts, are sufficiently important for us to ascertain their location and pattern prior to removal of the gall-bladder. Inadvertent injury to a normal or aberrant bile duct can result in morbidity and even mortality. Knowledge of the embryogenesis of these anomalies helps in the understanding of the location and pattern of these malformations. Almost all of these unusual bile duct arrangements can be recognised by following the rules of meticulous dissection and accurate knowledge of these anatomical aberrations.

Metastasis to pampiniform plexus from left renal adenocarcinoma presenting with acute varicocele.

A case of metastatic adenocarcinoma from the left kidney to the veins of the pampiniform plexus is described following initial presentation with an acute varicocele. It provides further evidence to support the retrograde venous route for intrascrotal secondary malignancy and also for low ligation of the left testicular vein at radical nephrectomy.

Light stimulated 'shunt-metabolism' succinate-alpha-ketoglutarate-isocitrate cycle and accumulation of citric acid in Aspergillus niger.

Studies with light of the visible range had shown that light plays significant role in the biosynthesis and accumulation of citric acid in Aspergillus niger. Accumulation of 14C-labelled carbon atoms in alpha-ketoglutaric, isocitric, succinic and glycolic acids in the cultures grown under illumination suggest a probable 'shunt-metabolism' leading to the succinate-alpha-ketoglutarate-isocitrate (SKI) cycle. This shunt metabolism minimizes the accumulation of citric acid in cultures due to depletion of intermediates.
