We present experimental results for patterns of Rayleigh-Bénard convection in a cylindrical container with static sidewall forcing. The fluid used was methanol, with a Prandlt number sigma=7.17 , and the aspect ratio was Gamma identical withR/d approximately 19 ( R is the radius and d the thickness of the fluid layer). In the presence of a small heat input along the sidewall, a sudden jump of t...

A 19-month-old girl with a history of myelomeningocele and Chiari malformation type II presented with abdominal pain. The initial abdominal examination was normal; however, within 24 hours, the umbilicus became protuberant and erythematous (Panel A). The white-cell count was elevated, with a large proportion of neutrophils. Computed tomography of the abdomen revealed a cystic mass, measuring 6....

A 31 year old man with a condyloma latum simulating a keratoacanthoma at the umbilicus is reported. The umbilicus should be included in the list of known sites of predilection for condylomata lata.

abdominal wall endometriosis, the commonest type of extra-pelvic endometriosis, may rarely develop spontaneously in the absence of prior surgical scar. we aim to report 3 cases with this unique characteristic, two of them with a diagnosis of unusual development of umbilical endometriosis and one with inguinal endometriosis, from the perspective of a general surgeon. because of the potential pit...

Background: Three-por t l aparoscop ic cholecystectomy (LC) has been reported to be technically acceptable. However, whether it offers any additional advantages remains controversial. Our aim was to compare clinical outcomes of the umbilicus saving 3-port LC versus standard 4-port LC. Methods: Medical records of 55 patients to whom either umbilicus saving 3-port LC or 4-port LC was planned were...

STUDY OBJECTIVE To determine the cephalocaudal relationship among the umbilicus, aortic bifurcation, and iliac vessels by direct measurement during laparoscopy. DESIGN Prospective, consecutive study (Canadian Task Force classification II-1). SETTING Tertiary referral center. PATIENTS Ninety-seven women undergoing operative laparoscopy. INTERVENTIONS The distance from the aortic bifurcat...
