Physicians can treat psoriasis patients with several effective treatments, however the response is individual and even the most effective therapies do sometimes not lead to a success of treatment. Currently, possible genetic markers that can predict individual therapy response are investigated. Up to now 45 genes have been identified to be associated with psoriasis [1].

Our latest developments in miniaturizing 3D printed microfluidics [Gong et al., Lab Chip, 2016, 16, 2450; Gong et al., Lab Chip, 2017, 17, 2899] offer the opportunity to fabricate highly integrated chips that measure only a few mm on a side. For such small chips, an interconnection method is needed to provide the necessary world-to-chip reagent and pneumatic connections. In this paper, we introduce simple integrated microgaskets (SIMs) and controlled-compression integrated microgaskets (CCIMs) to connect a small device chip to a larger interface chip that implements world-to-chip connections...

The conventional paradigm for characterizing surface overcharging and charge reversal is based on the so-called Stern layer, in which surface dissociation reaction and specific chemical adsorption are assumed to take place. In this article, a series of Monte Carlo simulations have been applied to obtain useful insights into the underlying physics responsible for these two kinds of anomalous phenomena at the interface of two dielectrics, with special emphasis on the case of divalent counterions that are more relevant in natural and biological environments...

Background: C7 has relatively unique anatomy compared to the remainder of the subaxial cervical spine (C3-C6) and upper thoracic spine. The C7 laminar has been previously reported in feasibility and biomechanical studies as an adequate fixation point in contrast to the lateral mass or pedicles, with few reports of its use in clinical practice. The purpose of this study was to review the safety and efficacy of using the C7 laminar as a fixation point in constructs involving the cervical spine and cervicothoracic junction...

Background: Multiple techniques are utilized for distal fixation in patients with neuromuscular scoliosis. Although there is evidence of benefit with S2 alar iliac (S2AI) fixation, this remains controversial. The objective of this study is to evaluate the radiological outcomes and complications associated with this surgical technique in a pediatric population. Methods: An observational retrospective case series study was performed. All pediatric patients between January 2011 and February 2014 diagnosed with neuromuscular scoliosis associated with pelvic obliquity, which required surgery with fixation unto S2AI, were included...

Orbital hypertelorism is an increased distance between the bony orbits and can be caused by frontonasal malformations, craniofacial clefts, frontoethmoidal encephaloceles, glial tumors or dermoid cysts of the root of the nose, and various syndromic or chromosomal disorders. We report a series of 7 cases of hypertelorism that were treated in our hospital. The underlying causes in our series were craniofacial clefts 0 to 14 (4 cases), craniofacial clefts 1 to 12 (1 case), and frontonasal encephalocele (2 cases), all congenital...

Isolated, full-thickness articular cartilage lesions of the glenohumeral joint can cause pain, mechanical symptoms, and impaired function. Reports on operative management of these injuries with arthroscopic techniques, such as marrow stimulation, have shown improvement in patient symptoms. In cases where the subchondral bone is involved, osteochondral allograft (OCA) transplantation has shown positive results for contained, focal cartilage defects. The technique for OCA transplantation to treat Hill-Sachs lesions has been reported in detail, and there are multiple case series reporting on the outcomes of OCA used for this purpose...

Here, we report a case of adult gastric volvulus that was treated using an upper gastrointestinal series and provide a review of relevant reports. A 55-year-old woman presented with upper abdominal pain. Abdominal computed tomography revealed mesenteroaxial gastric volvulus. We performed an upper gastrointestinal series after the placement of a nasogastric tube. We successfully performed detorsion by repositioning. There was no recurrence of gastric volvulus after the detorsion. However, considering the risk of recurrence, we also performed laparoscopic gastropexy...

A system using energy-dispersive X-ray diffraction (EDXRD) has been developed and tested using multivariate calibration for the quantitative analysis of tablet-form mixtures of common pharmaceutical ingredients. A principal advantage of EDXRD over the more traditional and common angular dispersive X-ray diffraction technique (ADXRD) is the potential of EDXRD to analyse tablets within their packaging, due to the higher energy X-rays used. In the experiment, a series of caffeine, paracetamol and microcrystalline cellulose mixtures were prepared and pressed into tablets...
