sp. nov., a novel bacterium isolated from the skin and nasal cavities of healthy pigs and calves.

Gram-positive coccoid bacteria were isolated from the nasal cavities of pigs and calves as well as from axillar and inguinal skin regions of pigs. Phylogenetic analysis of seven strains based on complete genome, 16S rRNA, , , and gene sequences and MALDI-TOF MS profiles revealed that they belonged to the genus with the closest relatedness to , subsp. and subsp.

Evaluation of soft tissue attachments to a novel intra-abdominal prosthetic in a rabbit model.

Background: Laparoscopic ventral hernia repair requires placement of an intraperitoneal prosthetic. Composite mesh types have been developed to address the shortcomings of standard meshes. The authors evaluated the host reaction to intraperitoneal placement of a novel composite material.

Repair of esophageal atresia with tracheoesophageal fistula via thoracotomy: a contemporary series.

Background: A recent series detailing thoracoscopic repair of esophageal atresia with tracheoesophageal fistula (EA/TEF) reported lower complication rates compared with historic controls. This study provides a contemporary cohort of patients repaired via thoracotomy for comparison with the recent large multi-institutional thoracoscopic series.

Methods: Records of patients with EA/TEF between 1993 and 2008 were reviewed.

Laparoscopic approach to adrenalectomy: review of perioperative outcomes in a single center.

Laparoscopic expertise increases the volume of adrenalectomies at referral centers. We report our 10-year experience with laparoscopic adrenalectomy. All laparoscopic adrenalectomies at a single institution were prospectively recorded in a surgical outcomes database.

Pushing the envelope in biomaterial research: initial results of prosthetic coating with stem cells in a rat model.

Background: Coating prosthetic for hernia repair with a patient's own cells could improve biocompatibility by decreasing inflammation and adhesion formation and by increasing tissue ingrowth and resistance to infection. The objective of this study was to prove the feasibility of prosthetic coating with stem cells and to assess its resistance to adhesion formation when implanted in an animal model.

Methods: Adult Lewis rat bone marrow stem cells were harvested and cultured.

Effect of bacterial exposure on acellular human dermis in a rat ventral hernia model.

Background: Effectiveness of acellular human dermis (AHD) as an alternative to synthetic mesh in contaminated fields has been described. Cellular migration after implantation and corresponding strength of attachment is not well documented. Our aim is to correlate AHD vascularization, fibroblast migration, and strength of attachment with presence of inflammatory cells in clean and contaminated fields.

Does liver appearance predict histopathologic findings: prospective analysis of routine liver biopsies during bariatric surgery.

Background: Nonalcoholic fatty liver disease is associated with morbid obesity. Liver biopsy is the reference standard for the diagnosis of nonalcoholic fatty liver disease. It is unclear whether the macroscopic liver appearance correlates with the histopathologic findings.

Probiotic acidified formula in an animal model reduces pulmonary and gastric bacterial load.

Background/purpose: We previously reported that a diet acidified with citric acid effectively reinforces gastric acid protection against bacterial colonization and translocation. In this study, our objective was to examine a biologically acidified formula hypothesized to be more physiologic than formula acidified with free acid. This study was Institutional Animal Care and Use Committee (IACUC) approved and designed to determine whether this diet is better tolerated and equally effective to acidification with citric acid against gut colonization and subsequent bacterial translocation in a premature infant rabbit model.

Maximizing the donor pool: use of right kidneys and kidneys with multiple arteries for live donor transplantation.

Background: Studies have shown donor and recipient outcomes to be equivalent for laparoscopic donor nephrectomy (LDN) and open donor nephrectomy. In the past, LDN has been avoided in the procurement of the right kidney or organs with multiple arteries. This study compares procurement of right and left kidneys as well as procurement of single- and multiple artery organs.

Laparoscopic versus open live donor nephrectomy: outcomes analysis of 266 consecutive patients.

Background: Minimally invasive surgical techniques have become the preferred method for live donor nephrectomy (DN) in many centers. We compared our experience with laparoscopic and open DN in a single institution.

Methods: Data for 266 consecutive live DNs were collected.

Combined open and laparoscopic approach to chronic pain after inguinal hernia repair.

Chronic groin pain is the most frequent long-term complication after inguinal hernia repair affecting up to 34 per cent of patients. Traditional surgical management includes groin exploration, mesh removal, and neurectomy. We evaluate outcomes of a combined laparoscopic and open approach to chronic pain after inguinal herniorrhaphy.

Formula fortified with live probiotic culture reduces pulmonary and gastrointestinal bacterial colonization and translocation in a newborn animal model.

Background/purpose: Acidified diets are protective against intestinal bacterial colonization and translocation. Probiotic diets are designed to modulate the intestinal flora to enhance mucosal immunity. This study was designed to determine if formula acidified with live probiotic decreases bacterial gut colonization and translocation, and is equally tolerated as other acidified diets.

Duodenal- jejunal bypass sleeve: a totally endoscopic device for the treatment of morbid obesity.

Morbid obesity affects over 15 million people in the United States. Nonsurgical management produces sustained weight loss in less than 5% of patients. Despite associated comorbidities, less than 1% of obese patients seek surgical intervention.

Surgical management of lipoblastoma.

Background/purpose: Lipoblastoma/lipoblastomatosis, a rare benign pediatric tumor composed of embryonic fat, most often presents as a rapidly growing mass in children younger than 3 years. This benign tumor locally recurs up to 25% of the time. This retrospective review was done to emphasize problems with diagnosis, management, and the approach to follow-up care.

Enoxaparin inhibits fibrin sheath formation and decreases central venous catheter colonization following bacteremic challenge.

Objective: Inhibition of fibrin sheath formation by enoxaparin decreases catheter colonization. Fibrin-binding radioactive tracer and catheter weights quantify fibrin reduction.

Design: Controlled experimental study of central venous line colonization.

Air-gun injuries: initial evaluation and resultant morbidity.

Severity of injuries from air-powered weapons can be underappreciated. Transformation of these weapons into toys makes them available to children. Our experience reveals the underestimated injury severity and emphasizes need for prompt trauma evaluation.
