Sudden sensorineural hearing loss (SSNHL) is a common otological disorder characterized by a hearing loss greater than 30 dB over three consecutive frequencies, in less than 72 hours. It has been established that platelet parameters, such as mean platelet volume, are associated with ischemic heart events, whose clinical manifestations are similar to those of SSNHL. Hence, we aimed to determine if the platelet count, mean platelet volume and platelet distribution width are related to the occurrence and severity of sudden sensorineural hearing loss. A case-control prospective study was conducted in a teaching hospital in Iran. One hundred-eight patients with SSNHL and an equal number of healthy, age- and sex-matched controls were enrolled in the study. Peripheral venous blood samples were collected from the subjects, and the platelet count, mean platelet volume and platelet distribution width were measured with an automated blood cell counter. Analysis of the audiometry and hematological test results using SPSS22 software showed no statistical correlation between the platelet parameters and the occurrence of SSNHL, but correlation coefficients showed a significant correlation between PDW and hearing loss severity in patients group. However, further investigation is required to unequivocally establish the absence of correlation between the platelet parameters and occurrence of SSNHL.
To study the clinical characters, the outcomes of treatments and the factors affecting treatment results of adenoid cystic carcinomas at Shahid Sadoughi Hospital and Shahid Ramazanzadeh radiotherapy center, Yazd, Iran. The clinical data of 31 patients with adenoid cystic carcinoma of any anatomic site diagnosed over an 8 year period (2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012), were investigated retrospectively. Data regarding patients' characteristics, pathological features and follow-up were obtained from patients records. Survival rate, local recurrence and distant metastasis were analyzed using Kaplan-Meier method. Prognosis factors were analyzed by Log-rank test and Cox regression. The study included31 patients with adenoid cystic carcinoma. The mean age at presentation was 50.2 ± 24.8 years. There were 11 (35.5 %) males and 20 (64.5 %) females with a female predilection (M:F = 0.55:1). Parotid gland was the most common site (8/31, 25.7 %) followed by submandibular gland (7/31, 22.6 %). Perineural invasion was detected in 67.7 % of the cases. Positive surgical status was reported in 48.4 % of the specimens. Metastasis was detected in 25.8 % of the patients and the most common site of distant metastasis was lung. Overall survival rates at 2, 5, and 7 years were 95, 75, and 57 % respectively. Margin status showed significant effect on survival (P value = 0.01). Positive surgical margin is an important factor affecting the prognosis of the patients with adenoid cystic carcinoma. Surgery with negative surgical margin is the first choice of treatment for the patients with adenoid cystic carcinoma. Our findings show that the prognosis of patients with adenoid cystic carcinoma in our center is fair.
In the current study, we evaluated the effectiveness of uvulopalatopharyngoplasty (UPPP) in treatment of patients with obstructive sleep apnea (OSA) syndrome. All patients were previously received medical treatment but their symptoms did not resolve. A prospective study was conducted in Shahid Sadoughi Hospital in Yazd, Iran. Several sleep indices were evaluated using polysomnography (PSG) in all patients before performing UPPP and tonsillectomy. All patients were visited 6 months after surgery and PSG was repeated to assess the efficacy of surgical intervention. A total of 48 patients were enrolled and underwent UPPP and tonsillectomy. Six months after surgery, significant improvements were observed in all indices of sleep (apnea-hypopnea index, respiratory distress index, arterial oxygen saturation, and snoring index). The score of daytime sleepiness (assessed by Epworth score) was also improved. According to the result of this study, using UPPP surgery in patients with OSA can cause symptoms improvement in 64 % of cases. It seems thatMuller's maneuver test has assisted in briefly increasing success rate after surgery, though to prove this claim; other studies should be designed and performed in a randomized clinical trial.
Soft-tissue tumors are rare in the paranasal region. Lobular capillary hemangioma (LCH) is a distinctive vascular lesion most commonly seen on the skin and oral mucosa in the fourth and fifth decades of life. Forasmuch as the nasal cavity and paranasal sinuses are rare locations for LCH, it is not well known by many ENT surgeons. Here we present two cases of LCH of the ethmoid sinus. These cases are being reported owing to their scarcity as per the literature published global.
