BACKGROUND: Female vaginoplasty reconstruction, by choice, is usually performed with adjacent tissue. However in some clinical conditions such as high urogenital confluence sinus, cloacal malformation with extreme vaginal hypoplasia, local tissue may not be available. When vaginal replacement is performed in pediatric patients intestinal segments is preferred to non-operative procedures that require continuative dilations. However mucus production, malignant transformation risk and diversion colitis are important side effects...

Short bowel syndrome (SBS) occurs in patients who have had extensive resection. The primary physiologic consequence is malabsorption, resulting in fluid and electrolyte abnormalities and malnutrition. Nutrient digestion, absorption, and assimilation may also be diminished by disturbances in the production of bile acids and digestive enzymes. Small bowel dilation, dysmotility, loss of ileocecal valve, and anatomical changes combined with acid suppression and antimotility drugs increase the risk of small intestinal bacterial overgrowth, further contributing to malabsorption...

Type 1 neurofibromatosis (NF 1), a rare genetic disease with autosomal dominant transmission, has typical dermatologic manifestations with pathognomonic Lisch nodules, and is rarely known for vascular alterations. Among these, aneurysmal dilatation is the most common form. We report a fatal case of massive hemothorax due to a spontaneous rupture of the left pulmonary artery branch micro-aneurysm in a NF 1 patient. Indeed, spontaneous rupture of these pathologic vessels is very rare in clinical practice and the literature, but, for its potentially life-threatening complications, there is the need for it to be taken into account in differential diagnosis...

We present the case of a 61-year-old patient with a history of essential thrombocythemia (ET) who was diagnosed as having aortic valve stenosis and dilatation of his ascending aorta. His aortic valve and ascending aorta were replaced under hypothermic circulatory arrest (HCA). No clear guideline exists for preoperative, perioperative, and postoperative management of cardiac surgery using HCA for ET patients. After performing risk assessment, we prescribed preoperative aspirin therapy and postoperative care was planned as usual for cardiovascular surgery in our establishment...

Cellulose microfibrils are the principal structural building blocks of wood and plants. Their crystalline domains provide outstanding mechanical properties. Cellulose microfibrils have thus a remarkable potential as eco-friendly fibrous reinforcements for structural engineered materials. However, the elastoplastic properties of cellulose crystals remain poorly understood. Here, we use atomistic simulations to determine the plastic shear resistance of cellulose crystals and analyze the underpinning atomic deformation mechanisms...

BACKGROUND: A new complication, longitudinal stent deformation (LSD), is increasingly reported with recent intracoronary stent designs. We experienced unusual cases of distal LSD caused by entrapment of a Lacrosse® non-slip element (NSE) balloon (Goodman Co., Ltd., Nagoya, Japan), which comes with three flexible nylon elements to prevent slippage. Accordingly, the aim of this study is to report the clinical experience of distal LSD caused by the NSE in our center and to investigate the incidence and mechanisms involved...

BACKGROUND: Catheter ablation (CA) is a well-known treatment option for patients with symptomatic drug-resistant atrial fibrillation (AF). Multiple factors have been identified to determine AF recurrence after CA, however their predictive value is rather small. Identification of novel predictors of CA outcome is therefore of primary importance to reduce health costs and improve long-term results of this intervention. The recurrence of AF following CA is related to the severity of left ventricular (LV) dysfunction, extend of atrial dilatation and fibrosis...

BACKGROUND: Labor pain is one of the most intense pains experienced by women, which leads to an increase in the number of women opting to undergo a cesarean delivery. Pharmacological and nonpharmacological analgesia methods are used to control labor pain. Epidural analgesia is the most commonly used pharmacological analgesia method. However, it may have side effects on the fetus and the mother. Light-emitting diode (LED) photobiomodulation is an effective and noninvasive alternative to pharmacological methods...
