Inverted papilloma of the urinary bladder in children: case report and review of prognostic significance and biological potential behavior.

Inverted papilloma of the urinary bladder is rare in the pediatric population. Despite several reports in the literature the prognostic significance and biological potential behavior of this lesion remain uncertain. The authors report a case of polypoid inverted papilloma of the urinary bladder in an 11-year-old boy and review its pathology. The pediatric population with this lesion is an ideal group to provide intense, long-term follow-up to define the biological behavior and prognosis significance of this lesion.

A phase variant of Azospirillum lipoferum lacks a polar flagellum and constitutively expresses mechanosensing lateral flagella.

Flagellation of a nonswimming variant of the mixed flagellated bacterium Azospirillum lipoferum 4B was characterized by electron microscopy, and polyclonal antibodies were raised against polar and lateral flagellins. The variant cells lacked a polar flagellum due to a defect in flagellin synthesis and constitutively expressed lateral flagella. The variant cells were able to respond to conditions that restricted the rotation of lateral flagella by producing more lateral flagella, suggesting that the lateral flagella, as well as the polar flagellum, are mechanosensing.

[Effect of a 36-hour fast on blood glucose and insulin responses to the glucose stimulus in the normal subject].

The authors show that it's been able to perform an oral glucose tolerance test on subjects after an 36 hrs 'fasting, providing that a feeding with 250 g of carbohydrates has been brought on the three days before fasting. Three oGTT were performed on 10 normal subjects and carried out as follow: the first after a 3 days' period of usual food intake, the second after a 36 hours 'fasting, the third after a new three days' period with the usual food intake. The first and the third glycemic and insulinemic responses to oGTT are not significantly different. However, after the third period, weight, triacylglycerolemic rate and fasting blood sugar levels are still significantly below the initial values.

Feeding frequency and nitrogen balance in weight-reducing obese women.

In a prospective trial, ten obese women, each her own reference, ate a 1200 kcal/d slimming diet in six meals a day compared with three meals a day during two 14-d periods. Loss of weight was slightly greater during the six-meal periods when loss of nitrogen was lower and thus loss of lean mass was also lower.

Effect of exchange of ham for boiled egg on plasma glucose and insulin responses to breakfast in normal subjects.

Blood glucose (BG) and plasma insulin (IRI) were measured during two breakfasts different only by the nature of proteins--egg (E) or ham (H)--in eight normal subjects. Compared with H, E led to a flattened BG response at 30, 40, and 50 min and to a sustained BG from 150 to 240 min. Integrated BG response was not significantly different between E and H. After E, the IRI response decreased at 90 min and 120 min (P less than 0.05). Integrated IRI response with E was significantly smaller than with H (P less than 0.025). The reasons for the effect of E ingestion on BG are not obvious; pancreatic and/or intestinal mechanisms may be involved. It is suggested that greater consideration be given to the protein composition of the test meals when they are used in studies of glucose homeostasis.

ANCA-associated necrotizing/granulomatous glomerulonephritis in an elderly patient; importance of the renal biopsy.

ANCA-associated glomerulonephritis may present initially with renal symptoms, especially in elderly patients. We report a case of ANCA-associated glomerulonephritis in an 80-year-old female presenting with renal insufficiency and proteinuria. There was no evidence of systemic illness at admission. The major finding in the renal biopsy was the presence of granulomas. Additional testing for anti-neutrophil cytoplasmic antibodies (ANCA) was suggested. The ANCA test was positive confirming the diagnosis of ANCA-associated necrotizing/granulomatous glomerulonephritis. The patient responded well to adequate treatment with immunosuppressive therapy. This case demonstrates the importance of the renal biopsy in cases of ANCA-associated glomerulonephritis presenting with renal symptoms.
