#1

Scapholunate dissociation in stages 2 and 3 may lead to posttraumatic damage if left untreated. Different types of treatment have been described, including capsulodesis, tenodesis, and others. The purpose of all procedures is to avoid palmar shift of the distal scaphoid resulting in secondary arthritis (SLAC wrist). This study aimed to evaluate a modified dorsal ligamentoplasty in second- and third-degree scapholunate dissociation in a prospective study design. Furthermore, the study aimed to find out if there is a correlation between radiological and clinical parameters at follow-up and whether or not a SLAC wrist can be avoided...

Background Various operative approaches exist for osteoarthritis of the trapeziometacarpal joint. The aim of this two-centre study was to compare the results of Lundsborg's resection arthroplasty with the implantation of the Pyrocardan(®) spacer. Patients and methods We treated 20 patients with symptomatic osteoarthritis of the trapeziometacarpal joint in stage III / IV (Eaton-Littler classification). Twelve patients received Lundsborg's resection arthroplasty (centre 1), and in 8 patients a Pyrocardan(®) spacer was implanted (centre 2)...

Background High-pressure injection injuries are devastating injuries that often lead to an amputation of the primarily affected finger. The available literature mainly focuses on amputation rates, while there is a lack of knowledge regarding functional results. Patients and Methods Between 1998 and 2016, 47 cases of high-pressure injection injuries of the hand were registered in our department. Out of these, data of 26 patients, all men with an average age of 42 (18-62) years, were included in a retrospective follow-up examination after 4 (1-12) years...

A newly isolated GS-5 strain exhibiting heterotrophic nitrification, aerobic denitrification and denitrifying phosphorous removal was identified as Bacillus cereus GS-5 based on its phenotypic and phylogenetic characteristics. The isolate had exhibited efficient NH4(+)-N, NO3(-)-N, NO2(-)-N and PO4(3-)-P removal from nutrient spiked real domestic wastewater with average rates of 2.62, 2.69, 1.16 and 0.42mgL(-1)h(-1), respectively under aerobic condition. Metabolic inhibitor based mass balance analysis indicated that dinitrogen gas (41%), intracellular nitrogen (29%) and intracellular phosphorous (60%) were the major fates of the initial NH4(+)-N and PO4(3-)-P...

BACKGROUND: Symptomatic non-union of medial humeral epicondylar fractures is a limited entity. Some studies recommend surgical excision of the fragment, but the results are controversial. The purpose of this study is to evaluate the outcome of open reduction and internal fixation of a medial epicondyle non-union fragment. MATERIALS AND METHODS: A retrospective study was conducted in all the patients, who were operated in our hospital between the year 2010 and 2015 for symptomatic medial humeral epicondyle non-union...

BACKGROUND AND AIM: Knowledge of long-term outcomes following an index episode of acute severe colitis (ASC) can help informed decision-making at a time of acute exacerbation especially when colectomy is an option. We aimed to identify long-term outcomes and their predictors after a first episode of ASC in a large North Indian cohort. METHODS: Hospitalized patients satisfying Truelove and Witts' criteria under follow-up at a single centre from January 2003-December 2013 were included...

Although many stable disilenes (silicon-silicon doubly-bonded compounds) containing organic π-electron systems have been reported, stable disilenes with heteroaromatic groups remain rare. Herein, we report the synthesis of monodisilenyl-substituted thiophene 1, anthracene 4, acridine 5, and mesitylene 7 and bis(disilenyl)-substituted thiophene 2, 2,2'-bithiophene 3, and anthracene 6via reactions of dialkylmesityldisilenide 8 with the corresponding haloarenes. Disilenes 1-7 show absorption bands with contributions of intramolecular charge transfer (ICT) transitions from π(disilene) to π*(aryl)...

Photocatalytic syntheses of gem-difluoroolefins were performed using the B12-TiO2 hybrid catalyst during the C[double bond, length as m-dash]C bond reduction of α-trifluoromethyl styrenes with C-F bond cleavage at room temperature under nitrogen. The gem-difluoroolefins were used as synthetic precursors for fluorinated cyclopropanes.

Fixed-dose combinations are gaining popularity because they provide convenience while enhancing patient compliance. Literature examples suggest that many fixed-dose combinations are being rationalized and investigated for their potential utility in therapy. This article provides an introspection into the pharmacokinetic essentials that need to be considered prior to implementing a fixed-dose combination strategy. While the drug-drug interaction potential is an important question for the two drugs in a fixed-dose combination, the occurrence of a drug-drug interaction in itself is not a negative outcome for the proposed fixed-dose combination...

2-Substituted ethyl methacrylate monomers were characterized using sum frequency generation vibrational spectroscopy (SFGVS) to study the effect of substituent groups in the organization of the monomers at the monomer-hydrophilic quartz interface. The SFG spectra of the methacrylate-based functional monomers collected at the hydrophilic quartz interface were found to be different from those collected at the air-monomer interface. The various spectral profiles indicated different conformations of the molecular groups at the solid-liquid interface...

Three deprotonated 2-oxocarboxylic acids, glyoxylate, pyruvate, and 2-oxobutyrate (RCOCO2(-), R = H, CH3, CH3CH2) have been associated with MgCl2 and ZnCl2 to generate [RCOCO2MCl2](-) (M = Mg, Zn) complexes. Upon collision-induced dissociation these complexes all undergo efficient eliminations of CO2 and CO, via an intermediate [RCOMCl2](-) product, to ultimately give [RMCl2](-) products. The pyruvate and 2-oxobutyrate complexes also undergo efficient elimination of HCl to produce the enolate-metal complexes [H2C[double bond, length as m-dash]COCO2MCl](-) and [H3CHC[double bond, length as m-dash]COCO2MCl](-)...

Tao Ma, Xin Zheng, Xiao-Bo He, Kai-Jin Guo
INTRODUCTION: Open reduction and internal fixation of distal radius fractures often necessitates release of the brachioradialis from the radial styloid. However, whether this common procedure makes the reduction and fixation easier and affects the elbow function has not been fully understood. HYPOTHESIS: Brachioradialis (BR) release during volar plate fixation for type C distal radius fractures makes internal reduction and fixation easier, and it does not adversely affect wrist or elbow function...

AIMS: Evidence to support dietary modifications to improve glycemia during pregnancy is limited, and the benefits of diet beyond limiting gestational weight gain is unclear. Therefore, a systematic review and network meta-analysis of randomized trials was conducted to compare the effects of various common diets, stratified by the addition of gestational weight gain advice, on fasting glucose and insulin, hemoglobin A1c (HbA1c), and homeostatic model assessment for insulin resistance (HOMA-IR) in pregnant women...

BACKGROUND: The objective of the study was to evaluate the antidiarrheal and antinociceptive activities of ethanol extract and its chloroform and pet ether fraction of Phrynium imbricatum (Roxb.) leaves in mice. METHODS: In the present study, the dried leaves of P. imbricatum were subjected to extraction with ethanol, and then it was fractioned by chloroform and pet ether solvent. Antidiarrheal effects were tested by using castor oil-induced diarrhea, castor oil-induced enteropooling, and gastrointestinal transit test...

Guidelines for a healthy diet aim to decrease the risk of chronic diseases. It is unclear as to what extent a healthy diet is also an environmentally friendly diet. In the Dutch sub-cohort of the European Prospective Investigation into Cancer and Nutrition, the diet was assessed with a 178-item FFQ of 40 011 participants aged 20-70 years between 1993 and 1997. The WHO's Healthy Diet Indicator (HDI), the Dietary Approaches to Stop Hypertension (DASH) score and the Dutch Healthy Diet index 2015 (DHD15-index) were investigated in relation to greenhouse gas (GHG) emissions, land use and all-cause mortality risk...

Treatment of carpal tunnel syndrome (CTS) remains a challenge for hand surgeons. Carpal tunnel release (CTR) using nasal instruments has the advantages of both endoscopy and open surgery. In this study we aimed to explore the effectiveness of CTR using nasal instruments in Chinese patients.We present a case series of 49 cases of idiopathic CTS treated with the mini-incision technique using nasal instruments. The average recovery days before return to normal work and complications were recorded. The mean grip strength, pinch strength, and sensation were evaluated...
