Background/Aims: A drug-eluting stent for unresectable malignant biliary obstruction was developed to increase stent patency by preventing tumor ingrowth. The safety and efficacy of a new generation of metallic stents covered with a paclitaxel-incorporated membrane using a Pluronic(®) mixture (MSCPM-II) were compared prospectively with those of covered metal stents (CMSs) in patients with malignant biliary obstructions. Methods: This study was initially designed as a prospective randomized trial but was closed early because of a high incidence of early occlusion...

Todani classification is extensively used to guide the surgical strategy of choledochal cysts, but no systematic investigations on the distal management of intrapancreatic choledochal cysts have been conducted. This study reports the distal classification and management of choledochal cysts in adults based on the relation between the cyst and pancreatic duct. Patients with choledochal cyst who underwent operation, including distal management, in our department from January 2009 to December 2014 were retrospectively reviewed...

Reg Richard, Ingrid S Parry, Alexis Santos, W Scott Dewey
Accurate assessment of hand function following a burn is important for patient impairment determination. Goniometric measurement of hand or finger range of motion (ROM) is typically done measuring individual finger joints with the adjacent joint in extension (isolated) or measuring the joints in a fist position (composite). The purpose of this study was to compare if the total flexion motion of the summed angles of the metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints in burned hands were equal when performed in an isolated vs a composite manner...

BACKGROUND: Identifying highly sensitive and reliable neurological exam components are crucial in recognizing clinical deficiencies. This study aimed to investigate finger tapping performance differences between patients with CNS demyelinating lesions and healthy control subjects. METHODS: Twenty-three patients with multiple sclerosis or clinically isolated syndrome with infratentorial and/or cervical cord lesions on MRI, and 12 healthy controls were videotaped while tapping the tip of the index finger against the tip and distal crease of the thumb using both the dominant and non-dominant hand...

Bone strength is influenced by bone geometry, density, and bone microarchitecture, which adapt to increased mechanical loads during growth. Physical activity (PA) is essential for optimal bone strength accrual; however, less is known about how sedentary time influences bone strength and its determinants. Thus, our aim was to investigate the prospective associations between PA, sedentary time, and bone strength and its determinants during adolescence. We used HR-pQCT at distal tibia (8% site) and radius (7% site) in 173 girls and 136 boys (aged 9 to 20 years at baseline)...

HemoCD, which is composed of an iron(II)porphyrin such as 5,10,15,20-tetrakis(4-sulfonatophenyl)porphinatoiron(II) (Fe(II)TPPS) and a cyclodextrin (CD) dimer having a pyridine linker, represents a synthetic hemoglobin (Hb) model compound that exhibits reversible oxygen (O2 ) binding ability in aqueous solution at an ambient temperature. Therefore, hemoCD has the potential to be used as a totally synthetic artificial oxygen carrier. In this article, we describe the improvements of hemoCD related to its synthesis and O2 /CO selectivity...

Distally anchored uncemented modular tapered porous stems are often the preferred treatment in total hip arthroplasty revisions and failed subtrochanteric fractures. These conditions mainly affect elderly osteoporotic patients, with an increased risk of later fractures below the well-fixated implant. Treatment in secondary fractures with long looking plates is the recommended treatment, where stability is a key to fracture healing. We report a complicated case in which this was achieved by an innovative technique combing the trochanteric attachment bolt of the stem system and a locking plate with polyaxial screws...

Although robot-assisted pancreatic surgery has been considered critically in the past, it is nowadays an established standard technique in some centers, for distal pancreatectomy and pancreatic head resection. Compared with the laparoscopic approach, the use of robot-assisted surgery seems to be advantageous for acquiring the skills for pancreatic, bile duct and vascular anastomoses during pancreatic head resection and total pancreatectomy. On the other hand, the use of the robot is associated with increased costs and only highly effective and professional robotic programs in centers for pancreatic surgery will achieve top surgical and oncological quality, acceptable operation times and a reduction in duration of hospital stay...

PURPOSE: The presence of anterolateral ligament of the knee is still controversial, and some physicians prefer to call this structure anterolateral complex (ALC) to infer plural nature of structures involved. The purpose of this study was to describe the scanning techniques and to classify various sonographic appearances of the tibial-side ALC of the knee in subjects with anterior cruciate ligament (ACL) injury. It was hypothesized that sonographic abnormity of the ALC would be associated with ACL injury history...

PURPOSE: The aim of this study was to investigate the results of total knee arthroplasty (TKA) performed after varus distal femoral osteotomy (VrDFO), in comparison to a control group of TKAs performed as the primary intervention for arthrosis. Main hypothesis was that the medium term results for the two groups would be similar. METHODS: All TKAs performed after VrDFO were extracted from a single centre, prospective database of 4046 arthroplasties. A case-control study was performed with a control group comprising two TKAs performed as the primary intervention for each TKA after VrDFO, and matched for sex, age at intervention, body mass index, the type of arthrosis and the type of implant...

BACKGROUND: The diagnosis of gastro-oesophageal reflux disease (GERD) in clinical practice is limited by the sensitivity and specificity of symptoms and diagnostic testing. AIM: To determine if adding histology as a criterion and excluding patients with epigastric pain enhances the diagnosis for GERD. METHODS: Patients with frequent upper gastrointestinal symptoms who had not taken a proton pump inhibitor in the previous 2 months and who had evaluable distal oesophageal biopsies were included (Diamond study: NCT00291746)...

BACKGROUND: Carotid intima-media thickness (IMT) and plaque are recognized markers of increased risk for cerebrovascular events. Accurate visualization of the IMT and plaques is dependent upon image quality. Ultrasound contrast agents improve image quality during echocardiography-this study assessed whether contrast-enhanced ultrasound (CEUS) improves carotid IMT visualization and plaque detection in an asymptomatic population. METHODS & RESULTS: Individuals free from known cardiovascular disease, enrolled in a community study, underwent B-mode and CEUS carotid imaging...

BACKGROUND: Due to the inherent limitations of current generation BVSs, complex coronary artery disease often contains BVS unsuitable segments. Our aim was to assess the feasibility of a hybrid approach using bioresorbable vascular scaffolds (BVSs) and drug-eluting stents (DESs) for the treatment of complex coronary artery lesions not suitable for a scaffolding only approach. METHODS: A retrospective multicenter cohort analysis was performed on patients with complex de novo or in-stent restenosis lesions treated with a hybrid BVS (Absorb BVS, Abbott Vascular, Santa Clara, CA) and DES strategy...

Despite improvements in guidewire technologies, the traditional antegrade wire escalation approach to chronic total occlusion (CTO) recanalization is successful in only 60-80% of selected cases. In particular, long, calcified, and tortuous occlusions are less successfully approached with a true-to-true lumen approach. Frequently, the guidewire tracks into the subadventitial space, with no guarantee of distal re-entry into the true lumen. The ability to manage the subadventitial space has been a key step in the tremendous improvement in success rates of contemporary CTO percutaneous coronary intervention (PCI), whether operating antegradely or retrogradely...

REVIEW
Alberto Di Leo, Andrea Zanoni
Siewert III cancer, although representing around 40% of EGJ cancers and being the EGJ cancer with worst prognosis, does not have a homogenous treatment, has few dedicated studies, and is often not considered in study protocols. Although staged as an esophageal cancer by the TNM 7th ed., it is considered a gastric cancer by new TNM 8th ed. Our aim was to consolidate the current literature on the indications and treatment options for Siewert III adenocarcinoma. A review of the literature was performed to better delineate treatment indications (according to stage, surgical margins, type of lymphatic spread and lymphadenectomy) and treatment strategy...

A total of 74,745 unigenes were generated and 1975 DEGs were identified. Candidate genes that may be involved in the adventitious root formation of mango cotyledon segment were revealed. Adventitious root formation is a crucial step in plant vegetative propagation, but the molecular mechanism of adventitious root formation remains unclear. Adventitious roots formed only at the proximal cut surface (PCS) of mango cotyledon segments, whereas no roots were formed on the opposite, distal cut surface (DCS). To identify the transcript abundance changes linked to adventitious root development, RNA was isolated from PCS and DCS at 0, 4 and 7 days after culture, respectively...
