Calcifying fibrous pseudotumor of mesentery presenting with acute peritonitis: case report with immunohistochemical study and review of literature.

Calcifying fibrous pseudotumor (CFP) is a benign soft tissue lesion composed of thick collagen bundles, scattered fibroblasts, and psammomatous and dystrophic calcifications, located most commonly in the extremities and trunk of children and young adults. The present case in a 36-year-old woman is to the best of our knowledge the first report of a large CFP confined to the mesentery, which, because of torsion, led to acute peritonitis and emergency laparotomy. The typical histologic features were accompanied by a prominent myofibroblastic proliferation along with inflammatory response at the periphery of the lesion. The spindle cells of the lesion were positive for vimentin and focally for CD34 and smooth-muscle actin. Review of the literature and discussion of differential diagnosis in this report focuses on abdominal CFP and other intraabdominal soft tissue lesions, some of which may be precursors of CFP.

[Percutaneous feeding gastrostomy].

In the past 3 years 71 procedures for insertion of a percutaneous gastrostomy for enteral feeding were performed under X-ray control. The indication for gastrostomy was inability or refusal of the patient to swallow food, in the absence of mechanical obstruction of the gastrointestinal tract. The age range was 66-93 years (mean 82). Most patients had suffered strokes and some had dementia or Parkinson's disease. The procedure was successful in 69/71 patients (97%). 9 (12.6%) died within 30 days of causes related to their underlying condition, rather than to the procedure; 1 developed peritonitis and 6 (8.4%) developed minor infections at the site of entry of the gastrostomy tube. This is the first account of this technique to appear in the Hebrew medical literature. In our opinion the technique should be adopted as the preferred method for forming a gastrostomy, as it is quicker, safer and cheaper than the operative method, and even easier to perform than endoscopic percutaneous gastrostomy.

[Brain ultrasonography in diagnosis of intrauterine infections and of neonatal chromosomal disorders].

Ultrasonography of the brain is a primary, frequently used technique for the diagnosis of brain lesions in the neonate. Echogenic blood vessels in the thalamus and basal nuclei are an unusual finding in an ultrasonographic homogeneous area. We describe 2 neonates with echogenic blood vessels in this area who are, to our knowledge, the first such cases described in Israel: 1 with trisomy 13 and the other with a congenital cytomegalovirus infection. We focus pediatric attention on this simple, readily available method for diagnosing intrauterine infections and chromosomal aberrations in the neonate.
