An Unusual Cause of the Ileus: Non-Specific Stenosing Ulceration of the Small Intestine

Non-specific ulcerations of the small intestine are very rare. The cause and pathogenesis of these lesions remain obscure. The diagnosis of primary ileal ulcer is commonly overlooked and infrequently is established intraoperatively. Here we described a case of a 73-year-old woman who was presented to the emergency surgical department with the five days history of vomiting, distension, constipation, and abdominal pain. On physical examination abdomen was mildly distended and diffusely painful on palpation. Bowel sounds were present and active. Plain abdominal x-ray film showed ileus of the small intestine. Multislice computed tomography showed stenosing process of the ileum. Patient underwent exploratory laparotomy. Approximately 60 cm from the ileocecal valve ileum was inflamed and hypertrophic with a point of obstruction. Grossly, it appeared as a small intestine carcinoma. Involved segment of ileum including the point of obstruction was resected. Pathological examination showed ulceration of the ileum. After the surgery the patient made rapid recovery and was discharged from the hospital on the tenth postoperative day

Expression of EGF, EGFR, and proliferation in placentas from pregnancies complicated with preeclampsia

Objective: To investigate proliferation, EGF and EGFR expression of villous trophoblast (VTB), decidual cells (DC), and extravillous trophoblast (EVTB) in the placentas from pregnancies complicated with preeclampsia (PE) and to compare them with placentas from normal pregnancies. Methods: Twenty-nine PE placentas and 19 control placentas were studied for EGF and EGFR immunohistochemical expression (noted as week, moderate or strong). Proliferation was expressed as the proliferation index. The CK7 antibody was used to distinguish DC from EVTB. Results: DC and EVTB proliferation was significantly higher in PE placentas. EGFR and EGF expression showed no significant difference. Conclusion: Higher DC and EVTB proliferation in PE could contribute to PE development
