'Treatment of the sportsman's groin': British Hernia Society's 2014 position statement based on the Manchester Consensus Conference.

INTRODUCTION: The aim was to produce a multidisciplinary consensus to determine the current position on the nomenclature, definition, diagnosis, imaging modalities and management of Sportsman's groin (SG). METHODS: Experts in the diagnosis and management of SG were invited to participate in a consensus conference held by the British Hernia Society in Manchester, U.K. on 11-12 October 2012. Experts included a physiotherapist, a musculoskeletal radiologist and surgeons with a proven track record of expertise in this field. Presentations detailing scientific as well as outcome data from their own experiences were given. Records were made of the presentations with specific areas debated openly. RESULTS: The term 'inguinal disruption' (ID) was agreed as the preferred nomenclature with the term 'Sportsman's hernia' or 'groin' rejected, as no true hernia exists. There was an overwhelming agreement of opinion that there was abnormal tension in the groin, particularly around the inguinal ligament attachment. Other common findings included the possibility of external oblique disruption with consequent small tears noted as well as some oedema of the tissues. A multidisciplinary approach with tailored physiotherapy as the initial treatment was recommended with any surgery involving releasing the tension in the inguinal canal by various techniques and reinforcing it with a mesh or suture repair. A national registry should be developed for all athletes undergoing surgery. CONCLUSIONS: ID is a common condition where no true hernia exists. It should be managed through a multidisciplinary approach to ensure consistent standards and outcomes are achieved.

Debriefing after simulation-based non-technical skill training in healthcare: a systematic review of effective practice.

Non-technical skills training in healthcare frequently uses high-fidelity simulation followed by a facilitated discussion known as debriefing. This type of training is mandatory for anaesthesia training in Australia and New Zealand. Debriefing by a skilled facilitator is thought to be essential for new learning through feedback and reflective processes. Key elements of effective debriefing need to be clearly identified to ensure that the training is evidence-based. We undertook a systematic review of empirical studies where elements of debriefing have been systematically manipulated during non-technical skills training. Eight publications met the inclusion criteria, but seven of these were of limited generalisability. The only study that was generalisable found that debriefing by novice instructors using a script improved team leader performance in paediatric resuscitation. The remaining seven publications were limited by the small number of debriefers included in each study and these reports were thus analogous to case reports. Generally, performance improved after debriefing by a skilled facilitator. However, the debriefer provided no specific advantage over other post-experience educational interventions. Acknowledging their limitations, these studies found that performance improved after self-led debrief, no debrief (with experienced practitioners), standardised multimedia debrief or after reviewing a DVD of the participants' own eye-tracking. There was no added performance improvement when review of a video recording was added to facilitator-led debriefing. One study reported no performance improvement after debriefing. Without empirical evidence that is specific to the healthcare domain, theories of learning from education and psychology should continue to inform practices and teaching for effective debriefing.

Comparative in vitro activity of penicillin G, levofloxacin, moxifloxacin, telithromycin, pristinamycin, quinupristin-dalfopristin and linezolid against ofloxacin-intermediate and -resistant Streptococcus pneumoniae.

Screening by ofloxacin disk was carried out on 1158 strains of Streptococcus pneumoniae in order to investigate the in vitro bacteriostatic activity of penicillin G, levofloxacin, moxifloxacin, telithromycin, linezolid, pristinamycin and quinupristin-dalfopristin against ofloxacin-intermediate and -resistant S. pneumoniae strains. It was concluded that these new antimicrobial agents could be useful for the treatment of pneumococcal infections caused by penicillin-sensitive and -resistant S. pneumoniae, and would represent a valid therapeutic option for patients allergic to beta-lactams, should they prove to be potent in vivo.

Villous adenoma of the colon with electrolyte depletion.

The case is presented of a villous adenoma of the colon associated with profuse, watery diarrhoea of such severity as to cause dehydration and electrolyte depletion.

Evaluation of a new fibre colonoscope the Olympus TCF-2L.

Experience with the new Olympus twin channel TCF-2L colonoscope is presented. Based on 60 examinations including 25 polypectomies it is concluded that the instrument when compared with other colonoscopes is easier to handle and its advancement within the colon is faster, smoother and therefore less disagreeable to the patient. The proximal colon is easier to reach than previously experienced. Polypectomy and retrieving of polyps can efficiently be undertaken. This instrument will undoubtedly further enhance the usefulness and therapeutic value of fibre colonoscopy.

Metastatic hepatoma in the stomach masquerading as a leiomyoma.

Metastatic hepatoma in the stomach is rare. A case is described in which a gastric tumour appeared to be a leiomyoma, but after laparotomy proved to be an isolated secondary deposit from a hepatoma.

Non Campylobacter pylori spiral organisms in the gastric antrum.

Colonisation of the human gastric antrum with non Campylobacter pylori spiral organisms is described. A moderately severe histological gastritis was present despite the fact that these organisms, in contrast to C. pylori, were not closely associated with the epithelial cell surface. Although in vitro culture of the organisms was unsuccessful, in vivo culture was achieved in the mouse stomach. Further study of these spiral organisms should provide important clues to the role of bacteria in upper gastrointestinal disease.

Review of five cases of early gastric carcinoma.

Five cases of early gastric carcinoma (EGC) were seen in 12 months. The clinical features did not provide guide-lines to diagnosis, which depends on air contrast barium studies, endoscopic recognition of early malignancy, adequate biopsies, and their interpretation. Malignancy was present in an average of 60% of the biopsies taken. The most common type of lesion was IIc. The superficial nature of the malignancy was predicted at endoscopy in four cases but was unsuspected in one case which was considered to be advanced carcinoma until the resected specimen was throughly examined microscopically. The excellent prognosis of EGC was discussed. Only conservative surgery need be performed if the superficial nature of the lesion is recognized before operation.

Chronic erosive (verrucous) gastritis. A study of 108 patients.

Chronic erosive gastritis (C.E.G.) is a gastric mucosal lesionwith characteristic radiological and endoscopic appearances. Pyloric gland hyperplasia is seen on histological examination of biopsy specimens. C.E.G. is uncommonly reported in the English literature. In reviewing 3,800 upper gastro-intestinal endoscopies from 1971--1976, 108 patients were diagnosed as having typical features of chronic erosive gastritis, an incidence of 2.8%. There was a significant association with duodenal ulceration and an overall male predominance. The lesion can also co-exist with gastric ulceration and has been observed as an incidental finding in patients examined urgently for upper gastro-intestinal bleeding. In this context C.E.G. should be distinguished from acute mucosal erosions. Symptoms may relate to the accompanying peptic ulceration, although dyspepsia epigastric pain, fullness and nausea may possibly occur with C.E.G. alone.

Colonoscopy for unexplained rectal bleeding.

Two hundred and thirty-nine patients underwent colonoscopy for unexplained rectal bleeding. Local anorectal conditions were excluded by digital and proctosigmoidoscopic examinations and results of barium studies were negative for all patients. A cause for bleeding was found in 95 patients. Thirty-nine had adenomatous polyps, 24 had unrecognised inflammatory bowel disease, and most importantly 23 (10% of series) had carcinomas. Forty patients had diverticular disease, but nine of them were found to have an adenomatous polyp and four a carcinoma. Colonoscopy can contribute positively to the investigation and treatment of unexplained rectal bleeding and may prevent unnecessary laparotomy.

[Effect of the use of drinking water on the pathogenic fecal flora in a Sahel rural region]. / Retentissement sur la flore fécale pathogène de l'utilisation d'une eau potable en milieu rural sahélien.

Within the scope of a village hydraulic programme, in a Sahel rural area, an investigation was conducted in a school to determine the effect of the use of drinking water on fecal flora. One year following the installation of a hydraulic pump, it was observed that pathogenic salmonellae, shigellae and amoebic cysts had virtually disappeared. In contrast, the perennial character of viral contamination was demonstrated. Water guaranteed potable, therefore, appears to be an essential factor in the prevention of infections due to fecal pathogenic microorganisms. It is essential, however, that the areas surrounding the pumps be subjected to strict supervision to avoid pollution of the underground water sheet.

Effect of sodium amylosulfate (Depepsen) on the healing of duodenal ulcer.

Thirty-five patients with active duodenal ulceration were included in a double blind randomized trial, the antiulcer agent sodium amylosulfate (Depepsen), being compared with placebo. Diagnosis and healing were determined by duodenoscopy. Results showed, in the whole series, 13 of 18 patients treated with Depepsen healed, whereas 10 of 17 healed on placebo (P = 0.04). In the group of 23 outpatients, 6 of 11 healed on Depepsen, and 5 of 12 healed on placebo (P = 0.55). It was concluded that Depepsen did not accelerate the healing of duodenal ulcer.

Fas-independent apoptosis of activated T cells induced by antibodies to the HLA class I alpha1 domain.

In addition to their major function in antigen presentation and natural killer cell activity regulation, HLA class I molecules may modulate T-cell activation and proliferation. Monoclonal antibodies (MoAbs) that recognize distinct epitopes of HLA class I molecules were reported to interfere with T-cell proliferation. We show here that two MoAbs (mouse MoAb90 and rat YTH862) that bind to an epitope of the alpha1 domain of HLA class I heavy chain induce apoptotic cell death of activated, but not resting, peripheral T lymphocytes. Other reference anti-HLA class I antibodies specific for distinct epitopes of the alpha1 (B9.12.1), alpha2 (W6/32), or alpha3 (TP25.99) domains of the heavy chain decreased T-cell proliferation but had little or no apoptotic effect. Apoptosis shown by DNA fragmentation, phosphatidylserine externalization, and decrease of mitochondrial transmembrane potential was observed whatever the type of T-cell activator. Apoptosis did not result from Fas/Fas-L interaction and distinct though partly overlapping populations of activated T cells were susceptible to Fas- and HLA class I-mediated apoptosis, respectively. Induction of apoptosis did not require HLA class I cross-linking inasmuch as it could be observed with monovalent Fab' fragments. The data indicate that MoAb90 and YTH862 directed against the alpha1 domain of HLA class I trigger apoptosis of activated T lymphocytes by a pathway which does not involve Fas-ligand.

[Comparison of the results of the Etest and the method for determining minimum inhibitory concentrations in solid media for penicillin G, amoxicillin, and cefotaxime for S. pneumoniae. A multicenter study]. / Comparaison des résultats du Etest et de la méthode de détermination des concentrations minimales inhibitrices en milieu solide pour la pénicilline G, l'amoxicilline et le céfotaxime chez S. pneumoniae. Une étude multicentrique.

In 1996-1997 a multicentre study was carried out on 450 Streptococcus pneumoniae strains to compare the MICs and susceptibility categories obtained with the Etest (AB Biodisk) used under routine conditions in 22 hospital laboratories in the Rhône-Alpes region, France, with those obtained by the reference technique of agar dilution performed in a single coordinating centre. Each laboratory detected penicillin resistant pneumococci (PRP) by the oxacillin disk method (1 microgram and 5 micrograms) and determined the MICs of penicillin G (PG), amoxycillin (AMX) and cefotaxime (CTX) by the Etest. All the PRP strains were collected in the coordinating centre where MICs were carried out. The strains were classified as susceptible (S), intermediate (I) and resistant (R) according to the CASFM criteria (Comité de l'Antibiogramme de la Société Française de Microbiologie). The concordance results based on susceptibility categories are as follows: PG = 67.6%, AMX = 63.6%, CTX = 71.5%. Minor errors are as follows: PG = 31.2%, AMX = 36%, CTX = 28.5%. Major and very major errors are rare (0% to 0.6%). Agreement within 1 log2 dilution was obtained for about 80% of the strains. The minor errors results from strains clustering near the breakpoints 1 mg/l (PG) and 0.5 mg/l (AMX, CTX), and from practical difficulties in routine use of the Etest. These discrepancies may result in severe therapeutic problems. This study confirms the limits of the Etest. The authors insist on standardization and rigorous use of the Etest under routine conditions.

[Pneumococcus observatory data in the Rhône-Alps region. Results from 1996]. / Observatoire du pneumocoque en région Rhône-Alpes. Résultats de l'année 1996.

Throughout 1996, 22 hospital-based laboratories in the Rhône-Alpes region of France collected pneumococcal strains and used a standardized protocol to record the following data; patient age and sex; type of specimen; and determination of susceptibility to at least the following antibiotics: oxacillin 1 microgram and 5 micrograms, erythromycin (Ery), tetracycline (Tet), chloramphenicol (Chl), rifampin (Rmp), and loracarbef. For penicillin-nonsusceptible strains (PNSSs), which were identified based on results with oxacillin, MICs for penicillin G, amoxicillin (Amx), and cefotaxime (Ctx) were determined using the E Test, at the study site and agar dilution at the coordinating center. Of the 1153 strains, 65.5% were from adults and 31.8% from children; patient age was unknown in 2.7% of cases. PNSPs (MIC > 0.06 mg/l) contributed 32.9% of strains (I: 23.3%; R: 9.6%) and were more common in children (41.1%) than in adults (28.1%). The frequency of PNSSs varied across specimen types: 27.9% in blood cultures (305 strains), 15.6% in cerebrospinal fluid (32), 38.7% in protected bronchopulmonary specimens (31), 31.5% in unprotected bronchopulmonary specimens (434), 50.8% in acute otitis media (118), and 34.4% in other specimens (221). Among PNSSs, nonsusceptibility (I + R) to other antibiotics was variable: Ery, 62.1%; Tet, 41.5%; Chl, 40.4%; Rmp, 1.1%. Corresponding figures for the overall strain population were Ery, 33.3%; Tet, 22.7%; Chl, 22.8%; Rmp, 0.9%. In addition, 56.5% of PNSSs exhibited multiple drug resistance. Resistance to amoxicillin (MIC > 2 mg/l) was demonstrated for only 5 strains. No strains were resistant to loracarbef or cefotaxime. Serotypes of the 379 PNSSs were as follows: 23F, 26.6%; 14 (25.6%); 9V (18.2%), 6 (8.7%), 15 (5%), 19 (4.5%).

[Rhône-Alpes observatory of Streptococcus pneumoniae in 1999: 35 cases of meningitis]. / Observatoire Rhône-Alpes du pneumocoque en 1999: 35 cas de méningites.

In 1999, in Rhône-Alpes region, in a survey of resistance to antibiotics of Streptococcus pneumoniae, 35 cases of meningitis were observed. A retrospectic questionnary was sent to each participant. MICs to Penicillin, Amoxicillin and Cefotaxime were determined with ATB-PNEUMO gallery or E-test and by disk diffusion for the other antibiotics. The results were interpreted according to the recommendations of the CA-SFM. Mean age was 38.1 years (range : 1 month -78 years) and sex-ratio 2/5. Eight patients had previously received antibiotics, 22 patients had risk factors and 23 were transferred in intensive care unit. The patients received C3G + glycopeptide in 15 of 16 children and in 13/19 adults according to the consensus recommendations. Diagnostic was made on the direct examination of CSF in 83%, and blood cultures was positive in 74.3% of cases. The percentage of PRP was 48.6% with 17.1% of intermediate-amoxicilline and 14.3% intermediate-cefotaxime strains. Resistance to trimethoprim-sulfamethoxazole was 45.7%, to chloramphenicol 30% and to fosfomycin 6.9%. All the strains were susceptible to rifampicin and vancomycin. Among the 17 PRP strains, 7 were belonging to serotype 6 (6 in children). The clinical outcome was fatal in 7 male cases (20%), without risk factors in 3 children and 6 of 7 strains were susceptible to penicillin. Six patients (17%) had auditive and/or neurologic sequellaes. This study shows that nearly 50% of strains isolated in meningitis, in Rhône-Alpes region, were not susceptible to penicillin, and confirms the frequency of sequellaes while the mortality is not related with the resistance of strains to the antibiotics.

[Evaluation of the E-test and the ATB-PNEUMo battery for determining the beta-lactam MIC for Streptococcus pneumoniae in daily practice]. / Evaluation du E-test et de la galerie ATB-PNEUMo dans la détermination des CMI aux bêtalactamines de Streptococcus pneumoniae en pratique quotidienne.

In 1999, during the survey of resistance of Streptococcus pneumoniae to antibiotics by 31 clinical laboratories of Rhône-Alpes area, MIC to penicillin (P), amoxicillin (AMX) and cefotaxime (CTX) of 877 PRP strains or with a diameter of inhibition to oxacillin inferior to 26 mm, were determined by each institution by E-test (n = 220 strains) or ATB-PNEUMO (n = 657 strains). MICs of these three antibiotics were determined by dilution in agar medium by the coordinating center. The essential agreement was respectively for ATB-PNEUMO and E-test 89% versus 84% for P (p > 0.05), of 86% vs 79% for AMX (p < 0.01), and of 91% vs 86% for CTX (p = 0.03). When the strains were classified in clinical category, the differences were significant (p < 0.001) for AMX (85% vs 71%) and for CTX (82% vs 75%) but not for P (73% vs 78%). ATB-PNEUMO method was more sensitive than E-test for the detection of strains susceptible to P (90 vs 73%), to AMX (83 vs 78%) and to CTX (80 vs 72%) and for the strains intermediate to AMX (90 vs 78%). On the contrary, E-test is more specific than ATB-PNEUMO for the detection of P-resistant strains (94 vs 86%). Finally, the specificity of both methods is the same for detection of P-S, AMX-R and CTX-I strains.
