An outbreak of Ochrobactrum anthropi bacteraemia in five organ transplant patients.

Nosocomial bacteraemia caused by Ochrobactrum anthropi occurred over a 1-month period in five organ transplant recipients, four of whom were in the same renal and pancreatic transplant unit. Bacteraemia occurred with cyclosporin A, azathioprine and steroids, and with a rabbit anti-thymocyte globulin (RATG) during the induction phase. RATG appeared to be the only common factor among the five cases.

Incidence of thyroid carcinoma in a common surgical practice: the problems.

Over a two-year period, seven hundred twenty-three operations for thyroid disease were performed in the department of endocrine surgery on 717 patients; 7.1% of these patients had neoplastic lesions. If we consider only the solitary nodules, the incidence is 8.

Hearing impairment: is it a public health problem among primary school pupils in Alexandria?

A hearing screening survey was conducted among the primary school students in Alexandria. It aimed at measuring the prevalence of hearing impairment among students and studying the predisposing factors of hearing problems. The schools of the middle educational region were selected to carry out the study.

[Delayed perforation of the sigmoid colon following closed abdominal trauma. Apropos of a case report].

Blunt abdominal trauma and delayed colon perforations are not common and usually occur in patients sustaining other injuries, but also as isolated event. We report a case of delayed perforation of sigmoid colon, three days after a blunt abdominal trauma in a male adult. It was caused by disinsertion of sigmoid colon mesentery for about ten centimeters.

[Gastric schwannoma. Observations apropos of a case report of an schwannosarcoma with lymph node metastasis].

Schwannomas as neurofibromas are neurogenic mesenchymal tumors of the stomach. They arise from the Schwann cells of nerves of th gastric wall and are usually benign. The incidence of malignant schwannomas is uncertain because of the variable pathologic criteria used.

[Cystic formations of the mesentery. Apropos a case report of a pseudocyst of the lesser omentum].

Mesenteric cysts are rare intraabdominal tumors in surgical pathology. Their etiology has been subject to much discussion. Symptoms are variable and depend on specific complications.

An immunoradiometric assay for von Willebrand factor antigen to assess angiogenesis.

A method of determining the degree of vascularization of tissues would be of great value in dermatological research such as the investigation of neoangiogenesis in wounds and in the study of the vascular abnormality in psoriasis. We describe an adaptation of an immunoradiometric assay (IRMA) for von Willebrand factor antigen for this purpose. The results show that in endothelial cells in culture there was a good relationship between the number of cells and von Willebrand factor antigen measured by the IRMA.

Assessment of disease severity and outcome in the gravitational syndrome using pulsed A-scan ultrasound to measure skin thickness.

In order to investigate the prognostic significance of skin thickening in the gravitational syndrome, 54 patients and 10 normal control subjects were studied. Patients were investigated using a standard questionnaire, as well as recording the results of clinical history and a physical examination. To quantify the severity of the syndrome, an index of disease severity was devised on the basis of the clinical findings.

Changes in endothelial cell mass, luminal volume and capillary number in the gravitational syndrome.

The histopathological changes in the skin of 31 patients with the gravitational syndrome and 10 normal control subjects were studied. To quantify the clinical severity of the syndrome, a new index of severity was used. Histometric evaluation of the cutaneous vasculature was performed on biopsies taken from the edge of the ulcers in the 31 patients and from the medical aspect of the lower legs in control subjects.
