[The "wandering spleen" syndrome].
We describe a 26-year-old woman with thrombocytopenia discovered during gestation. On admission for evaluation of abdominal pain, torsion of an ectopic spleen was found. The spleen was removed and the thrombocytopenia resolved.
[The diagnosis and treatment of Fournier's gangrene].
We treated 2 women and 8 men suffering from Fournier's gangrene during 1990-96. 2 had diabetes, 1 suffered from ulcerative colitis and 1 was an alcoholic. In 8 of them the infection was triggered by a mixture of aerobic and anaerobic bacteria. Treatment consisted of repeated wide debridement and early colostomy. This aggressive approach resulted in relief of the septic signs within 24 hours and permitted early skin grafting of the wounds. 2 patients died due to sepsis that caused multiple organ failure. The 8 who survived were hospitalized for an average of 35 days. On follow-up examination 1-5 years later all patients had undergone closure of the colostomy and were completely rehabilitated. Fournier's gangrene is not rare in the geriatric population. We believe that early diagnosis and aggressive wide debridement, combined with early colostomy, are the keys to successful treatment.
Traumatic rupture of the intestine in patients with inflammatory bowel disease.
Three young patients suffering from inflammatory bowel disease were admitted to our hospital during the past year for extensive intestinal rupture caused by disproportionately minor trauma. There was almost no concomitant intra-abdominal injury. We believe that a minimal direct or acceleration/deceleration trauma to a preexisting diseased intestine might have caused extensive damage that was not apparent on admission. It was concluded that these patients should be carefully monitored and that their relative intestinal vulnerability should be borne in mind during diagnosis of and therapeutic planning for their condition.
A correlation between oestrogen receptors and tumour size in primary breast cancer.
Oestrogen receptor (OR) assay has an essential role in selecting therapy for breast cancer patients, OR status is probably also of prognostic value. The correlation between the size of the primary tumour and OR status was evaluated in 100 women with breast cancer. In 72 post-menopausal patients the OR average level was significantly higher in large primary tumours--T2, T3, when compared to OR levels of T1 tumours. In the 28 pre-menopausal women, this difference was not statistically significant. No correlation between OR level and stage of disease was found. Women presenting with large primary tumours do not necessarily have a poor prognosis.
Homogeneous substrate-labeled fluorescent immunoassay for human serum albumin.
A homogeneous substrate-labeled fluorescent immunoassay for human serum albumin (HSA) has been developed, similar to previously described immunoassays for Immunoglobulin G and Immunoglobulin M. HSA was covalently linked to 6-(7-beta-galactosylcoumarin-3-carboxamide) hexylamine. The resulting conjugate had minimal fluorescence at 450 nm (with excitation at 400 nm). However, when the acetal linkage of the galactosyl moiety was hydrolyzed by beta-galactosidase, a substantial increase in the fluorescence was obtained. This increase was specifically inhibited by antibody to HSA. A competitive binding immunoassay was established by letting the conjugate compete with HSA in the serum for the limited number of antibody-binding sites. The level of fluorescence resulting from the addition of enzyme was proportional to the amount of HSA in the serum. Precision, analytical recovery and serum dilution studies were carried out on the assay. The immunoassay was compared to an albumin assay using the dye-binding method.
