Wound infections in day-case hand surgery: a prospective study.

BACKGROUND: There is little published information about postoperative infection rates in day-case hand surgery and the possible factors promoting infection. RESULTS: We report on infection rates observed in day-case hand surgery of 1035 cases over a 2-year period performed by two consultant surgeons. Infection rates of just over 1% were observed. CONCLUSION: We believe that this low infection rate reflects seniority of surgeon, operative technique and short duration of operation

A Least Squares Approach to Estimating the Average Reservoir Pressure

Least squares method (LSM) is an accurate and rapid method for solving some analytical and numerical problems. This method can be used to estimate the average reservoir pressure in well test analysis. In fact, it may be employed to estimate parameters such as permeability (k) and pore volume (Vp). Regarding this point, buildup, drawdown, late transient test data, modified Muskat method, interference test, and other methods are equivalent to a separable least squares problem. The main advantage of LSM in the well testing problems is that the results would be confident and no trial and error is required. Furthermore, the given method requires a short time. The fast rate of convergence and high accuracy of the LSM are demonstrated through two examples. The current study concerns a modified Muskat method. The results of LSM combined with the modified Muskat method are compared with the other iterative and qualitative methods. The preliminary numerical results with both simulated and field data suggest that the method be capable of producing smooth interpretable estimates of reservoir parameters from data

Biosynthesis of silver nanoparticles using brown marine seaweed Padina boeregeseni and evaluation of physico-chemical factors

1415-1421Present investigation consists the green nanoparticles prepared by using both fresh and dry marine macroalga of Padina boeregeseni was reported and the physical and chemical factors such as time duration, pH, various mixing ratios of aqueous extract to AgNO3 solution and temperature that play vital role in the nanoparticles synthesis were assess. Maximum synthesis of silver nanoparticles was attained within 30 min at pH 8.5, 70°C and 1mM AgNO3. Characterization of silver nanoparticles was carried out based on UV-Vis spectrophotometry (418 nm). The size of nanoparticles synthesis with average of 43.3 nm was confirmed by scanning electron microscopy (SEM). X-ray diffraction (XRD) crystallography illustrated the silver nanoparticles crystalline nature. Fourier transform infrared spectroscopy (FTIR) shows that the function groups are hydroxyl, carbonyl, amine and phenol compounds of extract P.boeregeseni are involved in the reduction of aqueous AgNO3. This method of Ag-NPs synthesis does not use any toxic reagents and thus has potential for use in biomedical and agricultural application

Unusual case of aortic coarctation complicated by mycotic pseudoaneurysm and bicuspid aortic valve endocarditis

Coarctation complicated with mycotic pseudo-aneurysm is very rare. We are reporting a case of a 26-year-old man suffered from this pathology. As the incidence of mycotic pseudo-aneurysm is very rare in patients with aortic coarctation, the choice of this pathology for a patient presenting with unexplained fever is the only way to reduce the mortality risk

Acute neck pain, an atypical presentation of subarachnoid haemorrhage

Subarachnoid haemorrhage can be a massively debilitating condition with long‐term repercussions. The “classic” presentation of sudden‐onset severe headache normally raises suspicions. However, if the presentation is atypical, the diagnosis may be missed. We report on a 52‐year‐old man who presented with a 1‐day history of progressively worsening right‐sided neck pain spreading to the chest with associated symptoms of autonomic dysfunction. After initial stabilisation, the patient's Glasgow Coma Scale (GCS) score declined, with subsequent CT scan showing an extensive subarachnoid haemorrhage

The clinicopathologic association of c-MET overexpression in Iranian gastric carcinomas; an immunohistochemical study of tissue microarrays

Abstract Background c-MET is an oncogene protein that plays important role in gastric carcinogenesis and has been introduced as a prognostic marker and potential therapeutic target. The aim of this study was to evaluate the frequency of c-MET overexpression and its relationship with clinicopathological variables in gastric cancer of Iranian population using tissue microarray. Methods In a cross sectional study, representative paraffin blocks of 130 patients with gastric carcinoma treated by curative gastrectomy during a 2 years period of 2008–2009 in two university hospitals in Tehran-Iran were collected in tissue microarray and c-MET expression was studied by immunohistochemical staining. Results Finally 124 cases were evaluated, constituted of 99 male and 25 female with the average age of 61.5 years. In 71% (88/124) of tumors, c-MET high expression was found. c-MET high expression was more associated with intestinal than diffuse tumor type (P = 0.04), deeper tumor invasion, pT3 and pT4 versus pT1 and pT2 (P = 0.014), neural invasion (P = 0.002) and advanced TNM staging, stage 3 and 4 versus stage 1 and2 (P = 0.044). The c-MET high expression was not associated with age, sex, tumor location, differentiation grade and distant metastasis, but relative associations with lymph node metastasis (P = 0.065) and vascular invasion (P = 0.078) were observed. Conclusions c-MET oncogene protein was frequently overexpressed in Iranian gastric carcinomas and it was related to clinicopathological characteristics such as tumor type, depth of invasion, neural invasion and TNM staging. It can also support the idea that c-MET is a potential marker for target therapy in Iranian gastric cancer.

The dietary patterns derived by reduced-rank regression in association with Framingham risk score and lower DASH score in Hoveyzeh cohort study

Abstract The relationship between dietary patterns (DPs) and cardiovascular disease (CVD) has been the subject of much research, but given the significance of this disease, studying the factors affecting it through different methodological considerations is of utmost importance. This study aimed to investigate the association between the four dietary patterns (DPs) derived from reduced-rank regression (RRR) and the risk of CVD predicted by the Framingham Risk Score (FRS) in the Arab residence of Khuzestan, Iran. Furthermore, the predefined Dietary Approaches to Stop Hypertension (DASH) would be used as a comparative model to assess the validity of the extracted DPs. In this cross-sectional study, 5799 individuals aged 35–70 without a CVD diagnosis were selected among the participants of the Hoveyzeh cohort study (HCS). The Risk of CVD was assessed using the FRS model. A semi-quantitative food frequency questionnaire evaluated dietary intake. Four DPs were derived using RRR with 28 food groups as predictors and total protein (g/d), fiber(g/d), fat(g/d), and magnesium intake (mg/d) as response variables. Multinomial and binary logistic regression were used to assess the relationship of DPs with intermediate (10–20%) and high (> 20%) levels of FRS and lower DASH scores ( 20%) across quartiles of four identified DPs. After adjustment for potential confounders, higher tendency to 1st and 2nd DPs in Model 1, OR = 4.67 (95% CI 3.65; 6.01), OR = 1.42 (95% CI 1.13; 1.79) were presented accordingly. The 1st DP, characterized by higher intake of refined grains and lower intake of vegetables oil, sugar, mayonnaise and artificial juices, the 2nd DP characterized by higher intake of hydrogenated fat and lower consumption of tomato sauce and soft drink was associated with greater odds of CVD with the intermediate level of FRS. However, higher adherence to the 3rd DP, characterized by higher intake of fruits, vegetables and legumes and lower intake of fish, egg, red meat, processed meat, mayonnaise, sugar and artificial juices, the 4th DP characterized by higher intake of coffee, nuts and lower intake of sugar, mayonnaise and artificial juices was associated with a lower risk of FRS. Moreover, lower DASH score considered in binary logistic regression across quartiles of four identified dietary patterns. 1st and 2nd DPs were directly related to lower DASH scores, while 3rd and 4th DPs had high comparability with the DASH diet and inversely contributed to the lower DASH score. Total DASH score was significantly correlated to four derived DPs. Our findings confirm the current knowledge regarding the beneficial effects of healthy plant-based DPs and the avoidance of high-fat and processed foods to prevent CVD
