Perforation of appendiceal adenocarcinoma ex goblet cell carcinoid: a rare case.

Goblet cell carcinoid tumor is a rare form of carcinoid tumor of the appendix. It behaves more aggressively than classical carcinoid tumor of the appendix. Thus, special attention must be given to its disease course and treatment.

Portomesentric and splenic vein thrombosis (PMSVT) after bariatric surgery: a systematic review of 110 patients.

Background: Portomesenteric and splenic vein thrombosis (PMSVT) is a rare but potentially serious complication after bariatric surgery. No study has systematically analyzed its incidence and risk factors.

Objectives: To pool the data regarding PMSVT after bariatric surgery and determine its incidence and risk factors.

Enhanced resting-state dynamics of the hemoglobin signal as a novel biomarker for detection of breast cancer.

Purpose: The work presented here demonstrates an application of diffuse optical tomography (DOT) to the problem of breast-cancer diagnosis. The potential for using spatial and temporal variability measures of the hemoglobin signal to identify useful biomarkers was studied.

Methods: DOT imaging data were collected using two instrumentation platforms the authors developed, which were suitable for exploring tissue dynamics while performing a simultaneous bilateral exam.

Duodenal web associated with malrotation and review of literature.

Intestinal obstruction due to midgut malrotation in neonates is well known. The incidence of malrotation in newborns is around 1:500 and the symptomatic incidence is 1:6000 births. Duodenal web as a cause of intestinal obstruction is less common and is reported to be 1:10 000-1:40 000.
