Epididymo-orchitis in an extremely preterm infant

This is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/).Epididymo-orchitis (EO) is a rare condition in the neonatal period. An underlying uropathy is variably associated with EO in published cases and more frequently seen in older children. In this case report, a male baby born at 26 weeks gestation had confirmed congenital Escherichia coli septicemia. The E. coli was sensitive to gentamicin, and he was treated with 10 days of intravenous gentamicin and cefotaxime, with normalization of markers of infection. He did not have a urinary catheter at any stage. He developed recurrent E. coli septicemia 19 days after ceasing antibiotics, in association with a tender scrotal swelling. A urine culture could not be obtained prior to commencing intravenous antibiotics. Surgical exploration revealed a right pyocele and a viable right testis. He was treated with 2 weeks of intravenous piperacillin and tazobactam and a further 2 weeks of oral amoxycillin and clavulanic acid. Urological investigations were normal. No further episodes of EO occurred, and follow-up showed normal testicular growth. This case adds weight to existing literature which suggests hematogenous spread as the most frequent cause of neonatal EO, without urinary tract abnormality. EO as cause of recurrent sepsis in the neonate after apparently adequate treatment of antecedent blood born infection is highlighted. Surgical exploration confirmed diagnosis, and evacuation of the pyocele assisted resolution of systemic sepsis and decompressed the testis

Acute colonic pseudo-obstruction (ogilvie’s syndrome) or colonic perforation: A rare complication following cesarean section

Ogilvie’s syndrome or pseudo-obstruction of the colon shows up as a clinical picture of acute obstruction of the large bowel without an associated pathological lesion as usually occurs in older patients. Here, we report a case series of three cases of Ogilvie’s syndrome following caesarean section. The caesarean section seems to be the most common operative procedure associated with this syndrome. The diagnosis was made by plain X-ray of the patient’s abdomen, which revealed dilated gut loops or air under the diaphragm in case of perforation. The pathological cause seems to be the disturbance of the autonomic innervation of the colon. The colon should be decompressed rapidly using colonoscopy. Surgery should be reserved for cases that have complications or that have been refractory to conservative treatment. Of our three cases, one was treated successfully by colonoscopic decompression and IV neostigmine, whereas, rest two patients presented late with colonic perforation. So they were immediately taken for exploratory laparotomy

Bioactive Materials: A Short Review

In every field of dentistry and medicine, bioactive materials have been widely used. These materials are used for regeneration, repair, and reconstruction in the field of conservative dentistry and endodontics. These materials are used in different forms and composition and act directly on vital tissue, helping in its healing and repair. These materials directly function because of induction of various growth factors and different cells. This article summarizes the types and uses of bioactive materials

Laparoscopic Adjustable Gastric Banding in Australian adolescents: Should it be done?

“This is a post-peer-review, pre-copyedit version of an article published in Obesity Surgery. The final authenticated version is available online at: http://dx.doi.org/10.1007/s11695-017-2544-6”.Objective There are very few studies on laparoscopic adjustable gastric banding (LAGB) in obese adolescents with follow up for more than 36 months, let alone good prospective data beyond 24 months in Australian adolescents. We aimed to evaluate medium term (>36 months) safety and efficacy of LAGB in adolescents with severe obesity. Methods This is a prospective cohort study (March 2009–December 2015) in one tertiary referral hospital including obese adolescents (14–18 years) with a body mass index (BMI) >40 (or ≥35 with comorbidities) who consented to have LAGB. Exclusion criteria were syndromal causes of obesity, depression and oesophageal motility disorders. Main outcome measures include change in weight and BMI at 6, 12, 24, 36 and 48 months post LAGB; postoperative complications; and admissions. Results Twenty-one adolescents (median [interquartile range (IQR)] 17.4 [16.5–17.7] years, 9 males, mean ± SD BMI 47.3 ± 8.4 kg/m2) had a median follow up of 45.5 [32–50] months post LAGB. Follow up data were available for 16 adolescents. Weight and BMI improved significantly at all follow up times (all p < 0.01). The median maximum BMI loss was 10 [7.1–14.7] kg/m2. There were four minor early complications. Seven bands were removed due to weight loss failure/regain (two had also obstructive symptoms). Conclusions We have shown in the longest prospective LAGB postoperative follow up study of Australian adolescents that LAGB improves BMI in the majority of adolescents without significant comorbidities. LAGB is still a reasonable option to be considered as a temporary procedure to manage severe obesity during adolescence

Upper Gastrointestinal Function in Morbidly Obese Adolescents before and Six Months after Gastric Banding

“This is a pre-print of an article published in Obesity Surgery. The final authenticated version is available online at: https://doi.org/10.1007/s11695-017-3000-3”. © Springer Science+Business Media, LLC 2017 This author accepted manuscript is made available following 12 month embargo from date of publication (Nov 2017) in accordance with the publisher’s archiving policyBackground The effects of laparoscopic adjustable gastric band (LAGB) placement on upper gastrointestinal tract function in obese adolescents are unknown. Therefore, our aim was to determine the short-term effects of LAGB on esophageal motility, gastroesophageal reflux, gastric emptying, appetite-regulatory hormones, and perceptions of post-prandial hunger and fullness. Methods This study was part of a prospective cohort study (March 2009–December 2015) in one tertiary referral hospital. The study included obese adolescents (14–18 years) with a body mass index (BMI) > 40 (or ≥ 35 with comorbidities). Gastric emptying was assessed by 13C-octanoic acid breath test, pharyngeal, and esophageal motor function by high-resolution manometry with impedance (HRIM), and appetite and other perceptions using 100-mm visual analogue scales. Dysphagia symptoms were scored using a Dakkak questionnaire. Data were compared pre- and post-LAGB placement and at a 6-month follow-up. Results Based upon analysis of 15 adolescents, at the 6-month follow-up, LAGB placement: (i) led to a significant reduction in weight and BMI; (ii) increased fullness and decreased hunger post-meal; (iii) increased symptoms of dysphagia after solid food; and, despite these effects, (iv) caused little or no changes to appetite hormones, while (v) effects on gastric emptying, esophageal motility, esophageal bolus transport, and esophageal emptying were not significant. Conclusion In adolescents, LAGB improved BMI and altered the sensitivity to nutrients without significant effects on upper gastrointestinal tract physiology at the 6-month follow-up

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

Search for stop and higgsino production using diphoton Higgs boson decays

Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass
