RESUMO
Background: Tenotomy of tendon Achilles is one of the major components of Ponseti method and necessary to complete correction in about 80 to 90 % of patients, it is safely procedure can be done in outpatient office as percutaneous technique under local anesthesia or in operative room under general anesthesia as mini-open technique. This study was designed to evaluate effect of tendoachillis tenotomy either percutaneous or open on continuity of tendoachillis by open evaluation in relapsed club foot. Patient & method: This study was conducted on 18 individuals. They were divided into 2 equal groups: Group I: containing 9 patients both sex had previously percutaneous tenotomy is done and Group II: 9 patients both sex had previously open tenotomy is done. Results: percutaneous technique found easy dissection in 6 patients (66.7%) and difficult dissection in 3 patients (33.3%) and continuity found central and regular contour in 7 patients (77.8%) and fibrotic mass in 2 patients (22.2%), open technique found easy dissection in 5 patients (55.6%) and difficult dissection in 4 patients (44.4%) and continuity found central and regular contour in 5 patients (55.6%) and fibrotic mass in 4 patients (44.4%), Conclusion: the techniques tenotomy of tendoachillis had no effect on continuity of tendoachillis either open or closed techniques in management of club foot

PURPOSE: Clinical and radiological evaluation of the results of the technique of elevation and grafting of osteochondral marginal impaction fragment of posterior wall acetabular fractures. METHODS: Twenty patients available for this study had fracture acetabulum with marginal impaction fragment. Elevation, reduction and bone graft impaction of the defect were the technique in all cases. Follow-up was at least for 1 year. Evaluation of patient was done clinically by modified Merle d'Aubigné and Postel score and radiologically by Matta's criteria of reduction quality and that of radiological hip evaluation. Ficat criteria for avascular necrosis and Brocker criteria were used for evaluation of heterotopic ossification. RESULTS: Radiologically, according to the Matta's criteria of reduction quality there were anatomic reduction in 16 patients (80%) and satisfactory reduction in 4 patients (20%). Clinical assessments based on modified Merle d'Aubigné and Postel score include 4 (20%) excellent scores, 12 (80%) good scores, 3 (15%) fair results and poor in one patient who had revision by total hip replacement. CONCLUSION: Diagnose of marginal impaction fragment preoperatively makes operative technique by elevation, reduction, bone graft packing and fixation mandatory to obtain anatomic reduction and favorable outcome. This technique should be completed before final fixation of the main fracture acetabulum.

The gut microbiota is increasingly recognised as a key-player in defining the health status of the gastrointestinal tract. Recently, we demonstrated that colonisation of healthy germfree mice with a conventional microbiota (conventionalisation) elicits temporal and region specific host-microbe communication responses that lead to the establishment of a microbiota-accommodating homeostatic state within 30 days. Here, the microbiota composition profiles, mucosal transcriptomes and plasma-analytes in germ-free and conventionalised C57/BL 6 J mice were assessed to decipher the features of the distinctive and pivotal events occurring four days after initiation of the conventionalisation process. The dominance of the microbial genera Helicobacter, Sphingomonas and Mucispirillum in the gut microbiota coincided with the transient mounting of proinflammatory responses in the mucosa and the transiently elevated levels of specific (inflammatory) cytokines and amines in plasma. The overrepresented microbes have previously been associated with the potential to cause disease under certain conditions, illustrating that conventionalisation proceeds through a transient state that resembles situations associated with dysbiosis. However, no overt mucosal inflammation was observed, suggesting a pivotal role of the overrepresented bacterial groups in priming and maturation of the immune system during the process of conventionalisation. These findings imply that the transiently elevated relative overgrowth of particular microbial genera functions as pivotal adjuvants to elicit the corresponding proinflammatory cascades, which precede the full maturation of the different arms of the immune system following these events and is required to achieve a microbiota-accommodating homeostasis in healthy animals.

The influence of the gut microbiota on the nervous system, brain development and behaviour, in particular during microbial colonisation of the host, has recently been receiving profound interest. Our time-resolved mining of combined data analyses of the ex-germfree mouse intestine during a 30-day course of colonisation with conventional mouse faecal microbiota (conventionalisation), shed light on temporal altered expression of genes of which the products influenced functions of the nervous system. Plasma tryptophan and kynurenine levels reflected high indoleamine dioxygenase activity, which was supported by significant temporal induction of the encoding gene in all gut tissues. However, the majority of genes associated with neuronal development and function were reduced. Colonic substance P elevation in response to conventionalisation was higher only after 30-days. These results support a functional microbiota-neurohumoral relationship during conventionalisation and suggest a delayed neuronal response that is elicited only after the microbiota accommodating homeostasis has been accomplished.

The aim of the study was to describe the characteristics of acute hepatitis E in Greater Cairo. Patients with acute hepatitis E were identified through a surveillance of acute hepatitis using the following definition: recent (<3 weeks) onset of fever or jaundice, alanine aminotransferase at least three times the upper limit of normal (uln), negative markers for other causes of viral hepatitis and detectable hepatitis E virus (HEV) RNA. Comparison of the liver tests between acute hepatitis E and hepatitis A virus (HAV), case-control analysis (four sex-matched and age-matched (±1 year) HAV controls per case) to explore risk factors and phylogenetic analyses were performed. Of the 17 acute HEV patients identified between 2002 and 2007, 14 were male. Median age was 16 years (interquartile range 13-22). Compared with HAV (n = 68 sex-matched and ±1 year age-matched), HEV patients had higher bilirubin (mean (SD) 10.9 (5.7) uln versus 7.5 (4.4) uln, p 0.05) and aspartate aminotransferase levels (38.6 (27.1) uln versus 18.3 (18.1) uln, p 0.02). Co-infection (hepatitis C virus RNA or hepatitis B surface (HBs) -antigen positive/IgM anti-hepatitis B core (HBc) anitgen negative) was diagnosed in four patients. In univariate matched analysis (17 cases, 68 matched controls), HEV cases were more likely to live in a rural area than HAV controls (matched OR 7.9; 95% CI 2.0-30.4). Of the 16 isolates confirmed as genotype 1, 15 belonged to the same cluster with 94-98.5% identity in the open-reading frame 2 region. Our findings documented the sporadic nature of HEV in Greater Cairo, characterized a large number of Egyptian HEV genotype 1 strains and identified living in a rural area as a potential risk factor for infection.
