Purpose
In previous studies, a lack of antibiotic prophylaxis, smoking and obesity were described as factors that contribute to the development of a surgical site infection (SSI) after pilonidal disease (PD) surgery. In this study, we evaluated whether the volume of the excised specimen (VS) was a risk factor for SSI.Methods
The patients who underwent surgical treatment for PD from January 2010 through December 2011 were retrospectively evaluated in terms of SSI, time off work and healing time. The single and multiple explanatory variable(s) logistic regression analyses were performed.Results
One-hundred and sixty patients were included in the study. SSI occurred in 19 (11.9 %) patients. In the multiple explanatory variable logistic regression analysis, VS was emerged as a risk factor for SSI (OR 18.78, 95 % CI 2.38–148.10; P < 0.005). The healing time and time off work were longer when a SSI occurred (P < 0.001).Conclusions
This study suggests that the rate of SSI after the surgical treatment of PD is higher in patients with a high VS. A SSI significantly prolongs the healing time. Surgeons can use this data for assessing the SSI risk. As a preventive measure, prolonged use of an empiric broad-spectrum antibiotic may be beneficial in patients with a high VS. 相似文献4.

Kienböck's disease is a type of avascular necrosis which disrupts the biomechanics of the wrist as a result of the changes it creates in the lunate bone. Its treatment generally consists of osteotomies intended to relieve the pressure on the bone, pedicle bone grafting applications aiming to increase bone blood supply, and salvage procedures. Capitate forage is a safe and simple-to-apply surgical treatment method which is intended to enhance neovascularization of the lunate much like a radius osteotomy or core decompression 相似文献

Objective: Tinnitus is the perception of sound in the ears or head without any external or internal acoustic stimulation, and it is usually associated with hearing loss. In addition, it has been reported that there is a relationship between vestibular problems and sensorineural hearing loss. The aim of this study was to evaluate the vestibular function in patients with tinnitus without hearing loss.Methods: A total of 32 patients who complained only of tinnitus without hearing loss and 30 control subjects without tinnitus or hearing loss were included in this study. Oculomotor and caloric tests were performed on all subjects with videonystagmography. The tinnitus handicap inventory questionnaire, side and duration of tinnitus were recorded in all patients.Results: The caloric test was abnormal in 13 of 32 (40.6%) patients in the tinnitus group and was normal in all of the control group. Abnormal caloric responses in patients with severe tinnitus were more frequent than in patients with mild or moderate tinnitus. There was a statistically significant difference in the optokinetic gain values between the tinnitus and control groups.Conclusion: A relationship between tinnitus and abnormal caloric responses was determined. Tinnitus may be the first symptom of vestibular dysfunction. 相似文献

In eukaryotes, tripeptidyl peptidase II (TPPII) is a crucial component of the proteolytic cascade acting downstream of the 26S proteasome in the ubiquitin-proteasome pathway. It is an amino peptidase belonging to the subtilase family removing tripeptides from the free N terminus of oligopeptides. The 150-kDa subunits of Drosophila TPPII assemble into a giant proteolytic complex of 6 MDa with a remarkable architecture consisting of two segmented and twisted strands that form a spindle-shaped structure. A refined 3D model has been obtained by cryoelectron microscopy, which reveals details of the molecular architecture and, in conjunction with biochemical data, provides insight into the assembly mechanism. The building blocks of this complex are apparently dimers, within which the 150-kDa monomers are oriented head to head. Stacking of these dimers leads to the formation of twisted single strands, two of which comprise the fully assembled spindle. This spindle also forms when TPPII is heterologously expressed in Escherichia coli, demonstrating that no scaffolding protein is required for complex formation and length determination. Reciprocal interactions of the N-terminal part of subunits from neighboring strands are probably involved in the formation of the native quaternary structure, lending the TPPII spindle a stability higher than that of single strands. 相似文献

The purpose of this study was to investigate the relationships between the upper extremity functions, upper extremity strength and hand sensation in patients with Multiple Sclerosis (MS). Twenty-two patients with MS (mean age: 38.5 ± 8.31 years, median Expanded Disability Status Scale (EDSS): 2) and 10 healthy subjects were included. Upper extremity function was measured with the Nine-hole peg test, upper extremity strength (shoulder flexion-abduction, elbow flexion, pinch and grip) with hand-held dynamometer, hand grip dynamometer and manual pinch meter, threshold of light touch-pressure with Semmes-Weinstein monofilament, duration of vibration with 128-Hz frequency tuning fork, and distance of two-point discrimination with an aesthesiometer. Strength and functional level of the upper extremity, light touch-pressure, two-point discrimination, vibration sensations of the hand were lower in patients with MS compared with healthy controls (p < 0.05). Light touch-pressure sensation of thumb and index fingers, two-point discrimination of index finger and elbow flexion strength were found to be related with upper extremity function in patients with MS (p< 0.05). These results indicate that the hand sensation, upper extremity strength and function were affected in MS patients. Additionally upper extremity functions seem to be related with light touch-pressure and two-point discrimination sensations of the hand and elbow flexion strength. Upper extremity strengthening and sensorial training of the hand may contribute to the upper extremity function in patients with MS. 相似文献

Crimean-Congo hemorrhagic fever (CCHF) is a tick-mediated viral infection. Patients with CCHF may show various clinical presentations. The cause of this difference in the clinical course is not completely understood. Apoptosis is programmed cell death and plays an important role in regulating the immune system. Our knowledge of the role of apoptosis in CCHF disease is limited. We investigated the role of apoptosis and their relationship with the severity of the disease in CCHF. Thus, in 30 patients with CCHF and 30 healthy individuals, we analyzed the serum levels of cytochrome C, apoptotic protease activating factor-1 (Apaf 1), caspase 3, caspase 8, caspase 9, sFas, sFasL, perforin, granzyme B, and CK18 by enzyme-linked immunosorbent assay. This is the first study that research the serum levels of the mentioned apoptosis markers in adult patients with CCHF. We found that the serum levels of sFasL, cytochrome C, Apaf 1, caspase 3, caspase 8, caspase 9, perforin, granzyme B, and M30 were statistically significantly different in the acute phase of the disease compared with healthy individuals and patients in convalescent period. There was no association between the clinical severity of the disease and apoptosis markers. In conclusion, the results of our study suggested that the extrinsic and intrinsic apoptosis pathway play an important role in CCHF. 相似文献
