Obstructive colitis: an analysis of 50 cases and a review of the literature.

Obstructive colitis is an ulcero-inflammatory and necrotizing condition that occurs in the colon proximal to benign or malignant stenosing lesions. it is the result of ischemia due to impairment of blood supply secondary to elevation of the endoluminal pressure, distension of the colonic wall and other factors which impair adequate perfusion. The incidence among patients with colonic obstruction is reported at between 1 and 7%.

Distribution of systemic blood flow in lambs with an aortopulmonary shunt during strenuous exercise.

We studied regional blood flows with radioactive-labeled microspheres in 12 7-wk-old lambs with an aortopulmonary left-to-right shunt [59 +/- 3% (SE) of left ventricular (LV) output] and in 11 control lambs, at rest and during exercise at 80% of predetermined peak O2 consumption. At rest, systemic blood flow was similar in the two groups. Blood flow to the heart and diaphragm was substantially higher in the shunt than in the control lambs.

Low-grade immature teratomas with peritoneal gliomatosis; a case report.

Immature teratomas with peritoneal gliomatosis are rare. Eight cases have been registered by the Dutch Ovarian Tumor Committee and one patient, presented in this paper, was treated recently. The follow-up in these cases indicates a good prognosis, even in grade 2 teratomas.

Neuroendocrine carcinoid tumours of the breast: a variant of carcinoma with neuroendocrine differentiation.

Carcinoid tumours most frequently develop in the gastrointestinal tract but have been described in many organs of the body. In 1977 the first cases were reported in the mamma, followed by descriptions of argyrophilic carcinoid-like, neuroendocrine mammary tumours by many investigators who performed immunohistochemical and ultrastructural examinations. The existence of true carcinoids in the mamma is still a controversial issue.
