Intradermal botulinum toxin a for peristomal hyperhidrosis: a case study.

Background: Peristomal hyperhidrosis can interfere with pouch adherence, resulting in pouch leakage and peristomal skin damage.

Case: A patient with autonomic dysregulation resulting in excessive sweating (hyperhidrosis) experienced difficulty with adherence of her ileostomy appliance. Two hundred units of botulinum toxin A (BTX-A) were injected in the dermis of the surrounding skin in order to improve adherence of her pouching system and alleviate moisture of her peristomal skin.

Portomesenteric venous thrombosis following major colon and rectal surgery: incidence and risk factors.

Background: Portomesenteric venous thrombosis (PMVT) is an uncommon complication of abdominal surgery. The objective of this study was to assess PMVT risk factor profiles and patient outcomes after colorectal surgery.

Methods: A single center retrospective review of patients undergoing colorectal surgery was performed (2007-2012).

Dysplasia in ulcerative colitis as a predictor of unsuspected synchronous colorectal cancer.

Background: Endoscopic surveillance of patients with ulcerative colitis aims to prevent cancer-related morbidity through the detection and treatment of dysplasia. The literature to date varies widely with regard to the importance of dysplasia as a marker for colorectal cancer at the time of colectomy.

Objective: The aim of this study was to accurately characterize the extent to which the preoperative detection of dysplasia is associated with undetected cancer in patients with ulcerative colitis.

Colectomy for endoscopically unresectable polyps: how often is it cancer?

Background: Colonoscopy has an established role in reducing the burden of colorectal cancer through early detection and removal of polyps. For endoscopically unresectable polyps, colectomy is generally indicated to prevent malignant transformation or to remove cancer already present.

Objective: This study aimed to determine the incidence of malignancy and the factors predictive of malignancy in surgically resected benign polyps.

Superficialization of deep arteriovenous access procedures in obese patients using suction-assisted lipectomy: A novel approach.

Successful dialysis access necessitates superficial arteriovenous fistula (AVF) placement to facilitate identification of anatomical landmarks for safe cannulation. Suction-assisted lipectomy (SAL) may be an alternative to traditional surgical AVF revision procedures for placing fistulas more superficially. Three patients with an average body mass index of 45.

Estrogen modulation of NMDA-induced seizures in ovariectomized and non-ovariectomized rats.

The objective of this study was to examine the neuroprotective effects of estrogen in response to N-methyl-D-aspartate (NMDA)-induced seizures in both male and female rats. Thirty-eight Long-Evans rats were divided into five groups: ovariectomized females, non-ovariectomized females, ovariectomized females with estrogen replacement (10 microg 17beta-estradiol in 100 microl sesame oil), males given exogenous estrogen and males receiving no estrogen. Using stereotaxic surgery, a cannula was placed in the lateral ventricle for convulsant agent administration (20 microg of NMDA), while an electrode was placed into the hippocampus for seizure recording.
