BACKGROUND: Variable results regarding general surgery residency program (GSRP) impact on patient outcomes and charges are reported. The aim of this study was to determine any significant differences in patient outcomes and cost with a new GSRP. METHODS: We analyzed all laparoscopic appendectomies (lap-ap), cholecystectomies (lap-chole), and inguinal hernia repairs (IHR) performed before and after implementing a GRSP. RESULTS: Operative time significantly increased for lap-ap (p < 0...

Microbial infection is one of the most significant causes of ear diseases, but microbial profiles are very diverse according to the diseases and change over time. The purpose of the study was to clarify differences and chronological changes in causative pathogens among infectious ear diseases over the last 20 years, and to identify antibiotic resistance. In total, 1191 isolates were included from patients diagnosed with chronic otitis media without cholesteatoma (COM), cholesteatomatous otitis media (Chole), middle ear effusion (MEE), including acute otitis media and otitis media with effusion, and external otitis (EO)...

BACKGROUND: The optimal timing of cholecystectomy for patients admitted with acute gallbladder pathology is unclear. Some studies have shown that emergency cholecystectomy during the index admission can reduce length of hospital stay with similar rates of conversion to open surgery, complications and mortality compared with a 'delayed' operation following discharge. Others have reported that cholecystectomy during the index acute admission results in higher morbidity, extended length of stay and increased costs...

BACKGROUND: The aims of this prospective population-based cohort study were to identify the patient and hospital characteristics associated with emergency cholecystectomy, and the influences of these in determining variations between hospitals. METHODS: Data were collected for consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing the performance of emergency cholecystectomy were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2)...

OBJECTIVES/HYPOTHESIS: Benign paroxysmal positional vertigo (BPPV) is the most common vestibular disorder with an incidence between 10.7 and 17.3 per 100,000 persons per year. The mechanism for BPPV has been postulated to involve displaced otoconia resulting in canalithiasis. Although particulate matter has been observed in the endolymph of affected patients undergoing posterior canal occlusion surgery, an otoconial origin for the disease is still questioned. STUDY DESIGN: In this study, particulate matter was extracted from the posterior semicircular canal of two patients and examined with scanning electron microscopy...

BACKGROUND: Laparoscopic cholecystectomy is commonly performed, and several factors increase the risk of open conversion, prolonging operating time and hospital stay. Preoperative stratification would improve consent, scheduling and identify appropriate training cases. The aim of this study was to develop a validated risk score for conversion for use in clinical practice. PATIENTS AND METHODS: Preoperative patient and disease-related variables were identified from a prospective cholecystectomy database (CholeS) of 8820 patients, divided into main and validation sets...

HYPOTHESIS: Bacterial biofilm formation within cholesteatomas is responsible for increased persistence and tissue destruction and Pseudomonas aeruginosa deficient in biofilm formation (PAO1 ΔfleQ) are less virulent than the parent bacteria. BACKGROUND: Infected aural cholesteatomas have been demonstrated to be more destructive than uninfected cholesteatomas and infections are more persistent. The chronicity and persistence of infections within cholesteatomas may be because of the presence of biofilm formation...

Infection with Dicrocoelium dendriticum in humans is seldom to be reported in Egypt. This liver fluke, which commonly infects ruminants, has a complex life cycle with two intermediate hosts; the land snail and the ant. Human infection occurs by accidental ingestion of the second intermediate host. The present reported a patient suffered from recurrent acute chole-cystitis with chronic urinary schistosomiasis whose Kato stool examination showed Dicroceolium dendriticum eggs. He was successfully treated with Mirazid...

No data exist for vitamin A group and vitamin D2/D3 content in branded intravenous lipid emulsions (ILEs). Our goal is to evaluate and quantify their concentrations in different ILEs to assess whether they are clinically relevant. Analyses were carried out in triplicates on six ILEs: 1) 30% soybean oil-based, 2) 20% olive-soybean oil based, 3) 10 + 10% soybean - MCT coconut oil based, 4) 20% soybean-olive-MCT-fish oil based, 5) 20% soybean-MCT-fish oil based and 6) 10% pure fish oil based, respectively. Retinol group (vitamin A) and ergo-chole-calciferol (vitamin D2/D3) were analyzed and quantified by a quali-quantitative Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) method after potassium hydroxide alkaline hydrolysis, hexane extraction, reverse phase-liquid chromatography and specific multiple-reaction-monitoring (MRM) detection...

BACKGROUND: Edible mushrooms, especially the genus of Pleurotus, have been well studied for their nutrition as well as non-toxic medicinal properties. Recently, much attention has been paid to the therapeutic values of mushrooms in genus of Pleurotus with diabetes mellitus (DM), which was a complex metabolic disorder that induced by increased oxidative stress and characterized by hyperglycemia. However, scare attention has been paid to polysaccharides from P. djamor. Meanwhile, zinc is an essential trace element in the human body and it participates in various pathways of metabolism...

Hanna Cholé, Pierre Junca, Jean-Christophe Sandoz
In honeybees, two olfactory conditioning protocols allow the study of appetitive and aversive Pavlovian associations. Appetitive conditioning of the proboscis extension response (PER) involves associating an odor, the conditioned stimulus (CS) with a sucrose solution, the unconditioned stimulus (US). Conversely, aversive conditioning of the sting extension response (SER) involves associating the odor CS with an electric or thermal shock US. Each protocol is based on the measure of a different behavioral response (proboscis versus sting) and both only provide binary responses (extension or not of the proboscis or sting)...

BACKGROUND: Subclinical infections, manifest as biofilms, are considered an important cause of capsular contracture. Acellular dermal matrices (ADMs) are frequently used in revision surgery to prevent recurrent capsular contractures. OBJECTIVE: We sought to identify an association between capsular contracture and biofilm formation on breast prostheses, capsules, and ADMs in a tissue expander/implant (TE/I) exchange clinical paradigm. METHODS: Biopsies of the prosthesis, capsule, and ADM from patients (N = 26) undergoing TE/I exchange for permanent breast implant were evaluated for subclinical infection...

INTRODUCTION: Variation in outcomes from surgery is a major challenge and defining surgical findings may help set benchmarks, which currently do not exist in laparoscopic cholecystectomy. This study outlines a new surgical scoring system incorporating key operative findings. METHODS: English language studies (from January 1965 to July 2014) pertaining to severity scoring and predictors of difficult laparoscopic cholecystectomy were searched for in PubMed, Embase and Cochrane databases using the search terms 'Laparoscopic cholecystectomy or Lap chole' and/or 'Scoring Index or Grading system or Prediction of difficulty or Conversion to open' in various combinations...

INTRODUCTION: Cholecystectomy is one of the most common general surgical operations performed. Despite level one evidence supporting the role of cholecystectomy in the management of specific gallbladder diseases, practice varies between surgeons and hospitals. It is unknown whether these variations account for the differences in surgical outcomes seen in population-level retrospective data sets. This study aims to investigate surgical outcomes following acute, elective and delayed cholecystectomies in a multicentre, contemporary, prospective, population-based cohort...

BACKGROUND: Majority of the human population in semi-urban and urban areas in Nigeria are heavily reliant on well water as the main source of water supply for drinking and domestic use due to inadequate provision of potable pipe borne water. These groundwater sources can easily be fecally contaminated and thus, increase the incidence and outbreaks of preventable waterborne diseases. This study was carried out to determine the bacteriological quality of some well waters in Samaru, Z. MATERIALS AND METHODS: Samaru, Zaria located in Northern Nigeria, is a semi-urban university satellite town blessed with abundant ground and surface water...
