Surgical sutures are vulnerable to bacterial infections and biofilm formation. At the suture site, pain and undesirable, excess inflammation are additionally detrimental to wound healing. The development of a polymerized cyclodextrin (pCD) coated surgical suture introduces the capability to locally deliver both anti-inflammatory and anti-microbial drugs throughout the phases of acute and chronic healing. Local delivery allows for the improvement of wound healing while reducing related systemic side effects and drug resistance...

Laparoscopic gastric greater curvature plication (LGGCP) has been presented as an alternative to laparoscopic sleeve gastrectomy (LSG) for reversible reduction of stomach capacity without gastric reduction or stapling. We present a case of a 51-year-old Hispanic female with a BMI of 41.91 kg/m2 , who underwent (LGGCP) 5 years previously at another institution. Despite multiple interventions, the patient was unable to successfully lose weight, and the decision was made to reverse the procedure with a robot-assisted Roux-en-Y gastric bypass...

Snapping biceps femoris tendon is an uncommon cause of lateral knee pain. We report the case of a 15-year-old athlete with bilateral snapping biceps femoris tendons, painful over his right lateral leg during exercise. He underwent elective exploration of the right knee which revealed an accessory biceps femoris tendon with attachment to the anterolateral tibia. The accessory tendon was released and reinserted onto the fibular head with a Krackow suture. There were no perioperative complications, and he returned to full sporting activities within 3 months...

Fracture toughness characterizes the ability of a material to maintain a certain level of strength despite the presence of a macroscopic crack. Understanding this tolerance for defects in soft collagenous tissues (SCT) has high relevance for assessing the risks of fracture after cutting, perforation or suturing. Here we investigate the peculiar toughening mechanisms of SCT through dedicated experiments and multi-scale simulations, showing that classical concepts of fracture mechanics are inadequate to quantify and explain the high defect tolerance of these materials...

BACKGROUND: Arrest of fetal brain development and the fetal brain disruption sequence describe a severe phenotype involving microcephaly, occipital bone prominence, and scalp rugae. Congenital disorders of glycosylation are a heterogeneous group of inherited disorders involved in glycoprotein and glycolipid biosynthesis, which can cause microcephaly and severe neurodevelopmental disability. METHODS: We report an example of fetal microcephaly diagnosed at 36 weeks' gestation with a history of normal fetal biometry at 20 weeks' gestation...

Local recurrences are more common after abdominoperineal excision (APE) than after anterior resection of rectal cancer. Extralevator APE was introduced to address this problem. The post anal minimally invasive approach had been used by other authors for transperineal mesh rectopexy but not in cancer management. Our aim is to use the post-anal minimally invasive approach for better visualization and division of the levator Ani during the Extralevator abdominoprineal excision in 2 cases of carcinoma of the anal canal...

BACKGROUND: Minimally invasive gastric cancer surgery requires an extended liver retraction in order to provide optimal operative view, working space for lymph node dissection, and esophageojejunal reconstruction. Ideally, it should avoid reposition of the retractor, additional skin incision or puncture, and liver parenchyma injury. Herein, we introduced an intracorporeal W-shaped liver retraction technique (W-LRT) for minimally invasive gastric cancer surgery without an additional incision or abodminal puncture...

PURPOSE: To evaluate the possibility of using the intrastromal corneal ring segments (ICRSs) previously implanted as a depth reference for performing pneumatic dissection in deep anterior lamellar keratoplasty (DALK). METHODS: The depth of placement of 2 symmetrical ICRSs placed in the superior and inferior midperipheral cornea of 4 eyes of 4 patients with keratoconus was measured by means of anterior segment optical coherence tomography. Because of irregular and/or high astigmatism, DALK using pneumatic dissection was performed in all eyes...

The newborn mammalian cranial vault consists of five flat bones that are joined together along their edges by soft fibrous tissues called sutures. Early fusion of these sutures leads to a medical condition known as craniosynostosis. The mechanobiology of normal and craniosynostotic skull growth is not well understood. In a series of previous studies, we characterized and modeled radial expansion of normal and craniosynostotic (Crouzon) mice. Here, we describe a new modeling algorithm to simulate bone formation at the sutures in normal and craniosynostotic mice...

Broad ligament hernia is a rare type of internal hernia. We herein report a case of broad ligament hernia successfully treated by needlescopic surgery. A 41-year-old woman was referred to our hospital with a complaint of nausea and vomiting. Abdominal contrast-enhanced computed tomography showed diffuse dilatation of the small bowel accompanied by a caliber change at the right side of the uterus. She was thus diagnosed with small bowel obstruction due to incarceration through right broad ligament hernia. After bowel decompression, she underwent elective needlescopic surgery using 2- and 3-mm instruments...

Background and Aims: GI tract perforations and anastomotic dehiscence are increasingly effectively being repaired endoscopically; however, well-known and long-held surgical principles must still be honored. One important principle is that significant extraluminal contamination must be washed out, debrided, and drained in conjunction with repair of the defect if the wound is to effectively heal and resolve. Here we describe the use of endoscopic washout and debridement of extraluminal contamination at the time of luminal defect closure in a 7-patient series at our institution, with video demonstration of 2 patients in the series...

BACKGROUND: Egypt ranks fifth for the burden of viral hepatitis worldwide. As part of Egypt's renewed national strategy for the elimination of viral hepatitis, surveillance for acute viral hepatitis (AVH) was re-established during 2014-2017 to describe the current epidemiology and associated risk factors, and changes from surveillance conducted during 2001-2004. METHODS: Patients with suspected AVH were enrolled, completed a questionnaire, and provided blood for testing for hepatitis viruses A (HAV), B (HBV), C (HCV), D, and E (HEV) infections by enzyme-linked immunosorbent assay...
