Intramural course of a coronary artery is a rare association in patients with transposition of great arteries. Various techniques have been described for translocation of these during the arterial switch procedure, with mixed results. This report focuses on a novel technique that is reproducible and provides an alternative in this difficult subset of patients.

BACKGROUND: Peroral cholangioscopic lithotripsy is a useful procedure in patients with a normal gastrointestinal anatomy who have difficult-to-treat stones. We evaluated the usefulness of peroral direct cholangioscopy (PDCS) using single-balloon enteroscope (SBE) in patients with difficult-to-treat stones who had undergone Roux-en-Y reconstruction. METHODS: Among 118 patients (169 sessions) who underwent SBE-assisted endoscopic retrograde cholangiopancreatography to treat biliary stones after Roux-en-Y reconstruction, patients in whom it was difficult to remove biliary stones via a transpapillary or transanastomotic approach and difficult to switch to ultra-slim endoscope, were retrospectively enrolled...

Achieving a long-term esthetic implant restoration in the maxillary anterior area is sometimes unpredictable. This article reviews several risk indicators of implant mucosal recession and loss of interproximal papillae, and how to prevent these risks. Results obtained from the literature suggest that the following factors are strongly related to implant soft-tissue complications: buccally positioned implant placement, a thin gingival biotype, lack of an adequate amount of keratinized mucosa, implant placement after ridge augmentation procedures, an increased distance of tooth bone peak to the contact point, and an inadequate horizontal implant-tooth distance...

PURPOSE OF REVIEW: The continued success of bariatric surgery to treat obesity and obesity-associated metabolic conditions creates a need for a strong understanding of clinical nutrition both before and after these procedures. RECENT FINDINGS: Surgically induced alteration of gastrointestinal physiology can affect the nutrition of individuals, especially among those who have undergone malabsorptive procedures. While uncommon, a subset of patients may develop protein-calorie malnutrition...

To reduce the long data acquisition time of the common mechanical scanning based Ptychographic Iterative Engine (PIE) technique, the digital micro-mirror device (DMD) is used to form the fast scanning illumination on the sample. Since the transverse mechanical scanning in the common PIE is replaced by the on/off switching of the micro-mirrors, the data acquisition time can be reduced from more than 15 minutes to less than 20 seconds for recording 12 × 10 diffraction patterns to cover the same field of 147...

OBJECTIVES: Arterial switch operation is the treatment of choice in infants with transposed arterial trunks. It is technically challenging to perform in patients having usual atrial arrangement and concordant atrioventricular connections but having a left-sided aorta. Correction in this setting requires surgical expertise and precision. Here we review our experience with such patients. METHODS: Between January, 2002 and October, 2013, the arterial switch operation was performed in 20 patients in the combination emphasised above...

Partial unilateral lentiginosis (PUL) is an unusual pigmentary disorder characterized by numerous lentigines grouped within an area of normal skin. Although treatment is not necessary, many patients with facial PUL seek medical help for cosmetic reasons. There is no established standard treatment for PUL. Conventional lasers may cause postinflammatory hyperpigmentation because keratinocytes are injured during the process. Also, scarring, long downtime, and pain are important issues. A 19-year-old patient with facial PUL was successfully treated with low-fluence 1,064-nm Q-switched neodymium-doped yttrium aluminum garnet (QS Nd:YAG) laser...

A rapid, convenient and efficient DNA extraction method with no need for toxic agents and centrifugation was reported. A polypropylene microfuge (MF) tube was used as the substrate to immobilize polydopamine (PDA). The prepared PDA-coated MF (PDA@MF) tube was used as a pH-responsive platform for rapid extraction of DNA based on pH-induced charge switch of amino and phenolic hydroxyl groups in PDA coating. The extraction procedure is simple and can be finished in 25 min. The PDA@MF tube was applied for extraction of genomic DNA from foodborne pathogens in milk...

The biliopancreatic diversion with duodenal switch (BPD/DS), a modification of the classic Scopinaro procedure, carries the highest rate of success in terms of weight loss, comorbid resolution, and maintenance of weight loss. The substantial challenges, technical complexity, and expected roadblocks of adding BPD/DS option to the bariatric surgeon's resources are reflected in the number of BPD/DS procedure performed in the USA, being less than 1% of all bariatric surgeries. Adjustments to the length of the common channel and the size of the vertical sleeve would increase the pool of candidates for BPD/DS and offer comprehensive management of obesity and metabolic comorbidities...

We report here a case of possible donor-derived Candida stellimalicola infection after pancreas transplantation. Candida stellimalicola, an environmental non-filamentous yeast, was isolated from both the peritoneal fluid of the graft donor and the preservation fluid of the transplanted pancreas. Interestingly, this strain exhibited high minimum inhibitory concentrations to azoles. These results justified the use of echinocandins as therapy instead of fluconazole. This switch permitted a favorable outcome. To our knowledge, this is the first report of C...

The number of people classified as obese, defined by the World Health Organization as having a body mass index ≥30, has been rising since the 1980s. Obesity is associated with comorbidities such as hypertension, diabetes mellitus, and nonalcoholic fatty liver disease. The current treatment paradigm emphasizes lifestyle modifications, including diet and exercise; however this approach produces only modest weight loss for many patients. When lifestyle modifications fail, the current "gold standard" therapy for obesity is bariatric surgery, including Roux-en-Y gastric bypass, sleeve gastrectomy, duodenal switch, and placement of an adjustable gastric band...

BACKGROUND: Standardized Clinical Assessment and Management Plans (SCAMPs) are a quality improvement initiative designed to reduce unnecessary utilization, decrease practice variation, and improve patient outcomes. We created a novel methodology, the SCAMP managed episode of care (SMEOC), which encompasses multiple encounters to assess the impact of the arterial switch operation (ASO) SCAMP on total costs. METHODS: All ASO SCAMP patients (dates March 2009 to July 2015) were compared to a control group of ASO patients (January 2001 to February 2009)...

For many applications in the biomedical sector (especially for cell screening assays, guidance and migration experiments), gradient patterns comprising bioactive compounds over comparably (in regard to a cell size) large areas are key. Polymer pen lithography (PPL), as an inherent highly parallel and large area technique has a great potential to serve in the fabrication of such patterns. We present strategies for the printing of functional phospholipid patterns via PPL that provide tunable feature size and feature density gradients over surface areas of several square millimeters...

BACKGROUND: Anatomic correction of corrected transposition of the great arteries with associated lesions, utilizing the morphologic left ventricle as a systemic pumping chamber, is the preferred method in many centers. The purpose of this study was to analyze functional outcome after anatomic correction. METHODS: Between Jan 1997 and May 2016, 63 patients with corrected transposition of the great arteries and associated lesions underwent anatomic correction. Forty-two patients (67%) underwent palliation before correction, including 14 patients (22%) who required training of systemic ventricle...

Aims: Switching between oral anticoagulants and treatment discontinuation are common events related to therapy with non-vitamin K antagonist oral anticoagulants (NOACs). However, knowledge on the reasons leading to these treatment changes is scarce. The aim of this study was to identify clinical events preceding anticoagulant switching and NOAC discontinuation during oral anticoagulant therapy in patients with atrial fibrillation. Methods and results: We performed a nationwide register-based study including Danish atrial fibrillation patients initiating a NOAC between August 2011 and February 2016 (n = 50 623)...
