Defining Global Benchmarks in Elective Secondary Bariatric Surgery Comprising Conversional, Revisional, and Reversal Procedures.

Objective: To define "best possible" outcomes for secondary bariatric surgery (BS).

Background: Management of poor response and of long-term complications after BS is complex and under-investigated. Indications and types of reoperations vary widely and postoperative complication rates are higher compared to primary BS.

Vessel heterogeneity of TIMI frame count and its relation to P-wave dispersion in patients with coronary slow flow.

Background: The vessel heterogeneity of thrombolysis in myocardial infarction (TIMI) frame count (TFC) in patients with coronary slow flow (CSF) remains to be further evaluated, and the correlation between TFC heterogeneity and P-wave dispersion (PWD) has not been elucidated. We aim to investigate the vessel heterogeneity of TFC in coronary arteries, and its relation to PWD in patients with CSF and otherwise normal coronary arteries.

Methods: We studied 72 patients with angiographically documented CSF and 66 age- and gender-matched control subjects.

Primary mucosa-associated lymphoid tissue lymphoma of the esophagus masquerading as a benign tumor.

We report a case of primary esophageal low-grade B-cell lymphoma of MALT type in a 50-year-old Saudi male patient who presented to our hospital with a history of dysphagia and heartburn for more than 2 years. Endoscopy showed a large esophageal mass with an intact mucosa located in the distal esophagus, 28 cm-35 cm from the incisor teeth. Endoscopic ultrasonography (EUS) showed a large well demarcated sub-epithelial lesion 4 cm in width and 10 cm in length arising from the muscularis mucosa with mixed echogenicity consistent with benign leiomyoma.

Folic acid awareness among female college students: neural tube defects prevention.

Objective: To investigate the level of awareness among female college students on the importance of preconception folic acid supplementation in preventing neural tube defects (NTDs). We have also studied their response after educating them.

Methods: This is a questionnaire-based study.
