Polyorchidism revisited

Polyorchidism is a rare urogenital anomaly. A review of the literature has yielded 99 cases. We add one more report, and guidelines regarding the surgical management are suggested.     

Intravascular lymphomatosis presenting as systemic inflammatory response syndrome

Intravascular lymphomatosis is an unusual form of non-Hodgkin lymphoma characterized by intravascular proliferation of atypical lymphoid cells in multiple organs. It can cause systemic inflammatory response syndrome due to primary release of cytokines by the tumor cells or secondary release of cytokines after vascular occlusion by the tumor cells. It is a potentially fatal condition, because multiorgan failure can ensue due to thrombotic vascular occlusion. This is a very rare condition and most cases are diagnosed post mortem. We present a case of systemic inflammatory response syndrome and subsequent death from multiorgan failure in a patient with intravascular lymphoma.     

Oral glutamine attenuates surgical manipulation-induced alterations in the intestinal brush border membrane

BACKGROUND: Our earlier work has shown that surgical manipulation of the intestine results in oxidative stress and mucosal damage along with alterations in the brush border membrane (BBM). Glutamine feeding is known to offer protection against damage to mucosa under various conditions and this study looked at the effect of oral supplementation of glutamine or glutamic acid in the intestinal BBM alterations after surgical manipulation. MATERIALS AND METHODS: Control and rats pretreated for 7 days with 2% glutamine or glutamic acid or isonitrogenous amino acids, glycine, or alanine were subjected to surgical manipulation of the intestine. BBMs were isolated from the intestine and functional and structural alterations to these membranes were assessed and compared. RESULTS: Surgical manipulation resulted in oxidative stress in the enterocyte BBM and these changes included a decrease in alkaline phosphatase activity and alpha-tocopherol content along with an increase in lipid peroxidation parameters. A decrease in glucose transport by the isolated BBM vesicles suggested functional impairment. Surgical manipulation also resulted in phospholipid degradation possibly mediated by PLA(2) and membrane protease activation. Glutamine or glutamic acid supplementation prevented these changes but not by glycine or alanine. CONCLUSION: This study suggests that oral glutamine or glutamic acid supplementation prior to surgery can offer protection to the intestine and this might prevent postsurgical complications.     

Hypoglycaemic and hypolipidemic effect of ethanolic extract of seeds of Eugenia jambolana in alloxan-induced diabetic rabbits

The hypoglycaemic and hypolipidemic effect of ethanolic extract obtained from seeds of E. jambolana was investigated in alloxan-induced diabetic rabbits. Hypoglycaemic activity was assessed by reduction in fasting blood glucose (FBG) at 90min and also fall in peak blood glucose during glucose tolerance test (GTT) in sub-diabetic and mild diabetic (MD) rabbits, but in severe diabetic (SD) rabbits by reduction in FBG at 90min. Ethanolic extract (100mg/kg body weight) when given orally to sub-diabetic (AR) for 1 day, MD for 7 days and SD for 15 days showed significant fall in FBG at 90min (12% AR, 18.9% MD and 29% SD) and also produced 16.9% fall in peak blood glucose in AR and 21% in MD rabbits during GTT. When administered daily for 15 days to MD and SD rabbits, significant fall in FBG (41.3% MD, 31.6% SD) and glycosylated haemoglobin (GHb) levels (23.3% MD, 26.6% SD) were observed, while serum insulin level showed significant increase (32.8% MD, 26.9% SD). Liver and muscle glycogen content also increased. The ethanolic extract of seeds also exhibited significant hypolipidemic effect as evident from fall in total serum cholesterol (TC)/high density lipoprotein cholesterol (HDL-c) ratio, serum low density lipoprotein cholesterol (LDL-c) levels and decreased activity of HMG-CoA reductase. The histopathological studies of liver, pancreas and aorta in alcoholic extract treated diabetic groups revealed almost normal appearance.     

Synchronous RCC with NHL: A case report.

A 55year old man presented with cervical adenopathy of two months duration.Biopsy of the node showed T-cell lymphoma, which was confirmed by immunohistochemistry. An abdominal CT done for the staging work-up of the lymphoma, revealed a left renal mass which histologically proved to be renal cell carcinoma [RCC], gradeII, stage I. An association between RCC and lymphoma is rare and this case is documented for the synchronous and concurrent occurrence of non-Hodgkin's lymphoma [NHL] of T-cell type and RCC. Key words: RCC, Synchronous, NHL.     

Cryptosporidium and isospora belli diarrhoea in immunocompromised hosts

Cryptosporidium and isospora, two of the intestinal coccidian parasites known to be the causative agents of acute diarrhoea in animals, have now emerged as one of the main causes of prolonged life threatening diarrhoea in immunocompromised patients particularly so in patients with AIDS. Between June 1996 and December 1997, a total of 75 immunocompromised patients presenting with diarrhoea were investigated both for Cryptosporidium and Isospora. The study group consisted of cancer and AIDS patients with history of diarrhoea. Cryptosporidium oocysts were detected in 35 patients (46.7%). One of the faecal samples from an AIDS patient with diarrhoea showed the presence of both Cryptosporidium and Isospora oocysts. To the best of our knowledge, this is the second documented report of Isospora associated diarrhoea in an AIDS patient from India. The various techniques used for demonstration of these parasites were modified acid fast staining, Safranine Methylene-blue staining and direct immunofluorescence test.
