Subcutaneous emphysema (SE) is a condition often causing minimal symptoms, but sometimes it can be severe and even life-threatening. This study is the first great survey about SE. The aim of this study is to classify and evaluate the etiology, signs, symptoms, and management of SE. This retrospective study was performed by reviewing patients who had been diagnosed as having SE in Rasht, between January 2001 and January 2011. We classified the severity of SE in five grades including the (1) base of the neck, (2) all of the neck area, (3) subpectoralis major area, (4) chest wall and all of the neck area, and (5) chest wall, neck, orbit, scalp, abdominal wall, upper limbs, and scrotum. We excluded all patients in grades 1 and 2, because the symptoms and signs were not significant. Statistical analysis was carried out with SPSS 18. We collected 35 cases of SE with the mean age of 53±14.83 (71 % men). The most common cause of SE was pneumothorax with background of COPD and surgery in grade 5, trauma due to rib fracture in grade 4, and iatrogenicity in grade 3. We performed two bilateral 2-cm infraclavicular incisions. In our patients with infraclavicular incisions, expansion of the lung was better, and the patients' appearance improved. Infraclavicular incisions as a simple method for the management of SE can decrease the severity of SE with no cosmetic problem.

We conclude that preoperative diagnosis and early diagnosis of MH by using laparotomy and thoracotomy is useful for safe and effective repair. Also we suggest that resection of the hernia sac and insertion of a mesh are not necessary.

Otomycosis as a kind of external otitis can be caused by various species of fungi. To use the appropriate treatment, it is necessary to identify the causal agent of otomycosis. The aim of this study was to determine the pathogens that caused otomycosis and also the efficacy of different antifungal agents. 100 patients with diagnosis of otomycosis/otitis extern were entered in this study. Bacterial culture was performed by eosin methylene blue agar, blood agar; and Sabouraud dextrose agar was used to culture the fungal agents. Minimum inhibitory concentration test also was performed to determine the efficacy of Clotrimazole, Fluconazole, Ketoconazole and Nystatin on the fungal pathogens. Otomycosis was confirmed in 43% of patients by positive culture. The most prevalent fungal pathogen was Aspergillus niger which was sensitive to Clotrimazole, Fluconazole, Ketoconazole. Candida albicans was sensitive to all drugs, in which, the most sensitivity was due to fluconazole. The most frequent fungal pathogen in our otomycosis cases is A. niger, and most of fungi that caused otomycosis are sensitive to clotrimazole.

BackgroundLack of proper control of acute postoperative pain often leads to lingering or chronic pain. Several studies have emphasized the role of beta-blockers in reducing postoperative pain. Esmolol is a selective short-acting beta-blocker that produces few side effects. The purpose of this study was to examine the effect of intravenous intraoperative esmolol on postoperative pain reduction following orthopedic leg fracture surgery.MethodsIn a clinical trial, 82 patients between 20-65 years of age with tibia fractures and American Society of Anesthesiologists (ASA) physical status I & II who underwent surgery were divided into two groups. Group A received esmolol and group B received normal saline. Postoperative pain was measured at three time points: entering the recovery unit, and at 3 h and 6 h following surgery, using the Visual Analogue Scale (VAS). A P value of < 0.05 was considered significant.ResultsMean VAS scores at all three time points were significantly different between the two test groups (P = 0.02, P = 0.0001, and P = 0.0001, respectively). The consumption of pethidine was lower in group A than in group B (P = 0.004) and the duration of its effect was significantly longer in time (P = 0.026).ConclusionsIntravenous intraoperative esmolol is effective in the reduction of postoperative pain following leg fracture surgery. It reduced opioid consumption following surgery and delayed patient requests for analgesics.

BackgroundAccording to the existing literature, the Dynamic Hip Screw (DHS) is the preferred standard for the treatment of intertrochanteric fractures. However, some surgeons use other devices such as the Locking Compression Plate (LCP).ObjectivesIn this study, we compared the outcome of using DHS or LCP in intertrochanteric fractures.Materials and MethodsThis cross-sectional study was carried out on 104 patients who were referred to Pursina Hospital in Rasht, Iran with intertrochanteric fractures of the femur treated with either the DHS or LCP devices. Demographic features, existence or nonexistence of stability and operating time were obtained from questionnaires. During a 6-month follow-up after surgery, patients were interviewed to record variables such as Harris Hip Scores and complications. The patients were also interviewed on their final visit (between 9 and 31 postoperative months). The collected data was analyzed using SPSS.ResultsWe discovered that the number of incidences of limb shortening and device failure was higher for patients treated with the LCP device (P = 0.048 and P = 0.014). Patients treated with the DHS device had higher Harris Hip scores for both the 6-month postoperative and the final evaluation visits (P = 0.01 and P = 0.018).ConclusionsDespite the complications of fixation with the DHS device, it remains the most successful for treatment of intertrochanteric fractures.
