Hemangioma of the rectum: CT appearance.

An 18-year-old man who had severe recurrent rectal bleeding and hematuria was found to have a diffuse cavernous hemangioma of the rectosigmoid. A computed tomographic (CT) study was indicated to evaluate tumor extension and therapeutic possibilities. CT scanning revealed a large mass with phleboliths throughout the true pelvis and nodular indentations in the rectosigmoid wall involving the dome and posterior wall of the bladder. A nonhomogeneous and subtle enhancement of the lesion was noticed after injection of contrast medium.

Transient fungemia and Candida arthritis due to Candida zeylanoides.

A 37 year old man developed transient fungemia caused by Candida zeylanoides following a kidney and pancreas transplant. For the next seven months the patient had signs and symptoms of right knee arthritis. Candida zeylanoides was finally identified as the aetiological agent. Treatment with intravenous amphotericin B was successful. To our knowledge this is the first report of Candida zeylanoides arthritis.

[Comparative study of 2 dosages of low molecular weight heparin, PK 10169, in the prevention of thromboembolic incidents during treatment of 103 femur neck fractures].

Results of this study in the elderly with fractures of femoral neck, in whom their exists an enhanced thrombogenic risk, showed that the dose of 40 mg per 24 hours as one or two divided injections of enoxaparine was as effective as adapted subcutaneous doses of calcium heparinate. It was also less iatrogenic and easier to manage (biological assays were of little use apart from platelet counts). Clinical evidence of pulmonary embolism, or mortality, were not observed in this series of 103 patients.

Cellular infiltrate in renal graft rejection: T lymphocyte subsets detected by monoclonal antibodies.

We have examined the interstitial cellular infiltrate using monoclonal antibodies against T cells (Cris 1), helper/inducer T cells (OKT4) and suppressor/cytotoxic T cells (OKT8) by indirect immunofluorescence in renal biopsies taken from 14 transplanted patients during clinical episodes suggestive of acute (n = 9), chronic (n = 2) and no rejection (n = 3). Infiltrating T cells and T cell subsets were found to be significantly increased during all types of rejection (n = 11) as compared to no rejection (n = 3). Two types of biopsies could be distinguished according to the predominance of T cell subsets. In some biopsies (n = 6), OKT8+ cells were significantly more numerous that OKT4+ cells. In the remaining biopsies (n = 5), OKT4+ cells were more common that OKT8+ cells, the OKT4/OKT8 ratio being significantly higher. No association was observed between HLA mismatch and predominating T cell subset, neither for type nor outcome of graft rejection. Our results suggest that the OKT4+ cells may play a more important role than previously reported in renal graft rejection.

[Antibiotic sensitivity of bacteria isolated from pathological specimens and utilization of beta-lactams in an orthopedic surgery service].

From 1980 to 1984, computerized data on the sensitivity to the main antibiotics of 1991 strains isolated from clinical specimens were evaluated in relation to beta-lactam use and hospital activity in a unit of orthopedic surgery. No major variations were found in distribution of species throughout the study period, whereas sensitivity to antimicrobial agents changed. From 1980 to 1982, patients had postoperative prophylactic treatment with cephalosporin (cefazolin) for two days; during the same period, 59% of 557 Gram negative organisms were resistant to cefazolin and 31% of Staphylococci were resistant to methicillin (and to other antibiotics). In 1983 and 1984, cefazolin was replaced by intraoperative flash therapy with a penicillin-M (cloxacillin); concomitantly, sensitivity to cefazolin increased among Gram negative organisms (38% of 485 isolates were cefazolin-resistant; p less than 0.001) and Staphylococci (16% of 342 isolates were methicillin-resistant; p less than 0.001). Phage typing of S. aureus failed to disclose any epidemic outbreak. Since hospital activity remained the same throughout the period under study, it seems justified to correlate the increase in bacterial sensitivity observed to the decrease in use of cephalosporin, although other factors (microepidemic, isolation techniques) may be involved.

[Postoperative infectious risk in traumatic bone surgery and protocol for antibiotic therapy].

Eleven hundred and sixty eight traumatic cases have been operated on under constant conditions in a conventional operating room with filtered air and positive pressure using absolute filters of 99.999 efficiency. Two hundred and five were submitted to post-operative prophylactic administration of Cephalosporin (Cefazolin) for 2 days. The overall results showed 0.6 p. 100 of infection but 4 cases of severe sepsis were seen in the group of patients who had received prophylactic antibiotics. The authors have compared these results with those obtained during the previous period when the operating room was less modern. They conclude that this factor is of paramount importance. On the other hand, they have observed 2.1 p. 100 of contaminated drains without subsequent infection. They are concerned at the increase of gram-negative organisms resistant to Cefazolin (60 p. 100) and of Staphylococci resistant to Methicillin (30 p. 100). They conclude that the peroperative flash technique of the administration of Penicillin M is worthwhile.
