ABSTRACT
BACKGROUND: The nasal septum deviation is the most common deformity of the nasal, and that can be congenital or acquired. Despite many studies exist about the impact of nasal septum deviation on chronic sinusitis and also association between chronic otitis and mastoid pneumatization; few studies exist about the impact of nasal septum deviation on chronic otitis and mastoid pneumatization. AIM: The aim of this study was to evaluate the associations of nasal septum deviation and mastoid pneumatization and chronic otitis. METHODS: In this study review, all CT scans of PNS and Mastoid View in the imaging section from Imam Ali hospital in 2016-2017 years and cases of nasal septum deviation were enrolled. The nasal septum deviation was recorded, and the degree of nasal septum deviation in the coronal plane that showed the maximum deviation of the nasal septum was recorded. The volume of the mastoid cells automatically and directly was calculated using three diameter measurements (2 coronal diameters and 1 axial diameter) by the program. The software of SPSS 22 was used for statistical analysis. RESULTS: There was no relationship between nasal septum deviation severity and incidence of mastoid pneumatization in patients with nasal septum deviation (P > 0.05). There was relationship between nasal septum deviation severity and chronic otitis in patients with nasal septum deviation (P < 0.05). In patients with moderate and severe intensity of nasal septum deviation, the volume of mastoid air cells in deviation side was lower than the front side (P < 0.05). CONCLUSION: Based on the results of the CT scan, in patients with moderate and severe nasal septum deviation intensity, the volume of mastoid air cells in deviation side was lower than the front side. Also, there was a relationship between nasal septum deviation severity and chronic otitis.
ABSTRACT
An increasing body of evidence suggests that low vitamin D (25-[OH]-D) concentrations is linked to increased activity in multiple sclerosis (MS) patients and MS relapse. Therefore, the current study was aimed to evaluate vitamin D serum concentrations and its possible seasonal variations among MS patients with relapse. This prospective, descriptive study was conducted on patients with MS relapse who referred to the neurology center of Ali ibn Abi Talib Hospital in Zahedan during one year. Magnetic Resonance Imaging (MRI)-Spine was performed for 90 patients and serum samples were collected from patient to measure serum vitamin D levels using RIA KIT. Furthermore, the plaques in each patient's MRI were counted and then recorded. Descriptive and inductive statistics were conducted using statistical software. Our findings indicated a significant correlation between serum vitamin D level and cervical spinal cord plaques (p = 0.007, r = 0.28), while no association was revealed between serum vitamin D level and number of brain plaque. Furthermore, a significant association was also observed between number of cervical spinal cord plaques and serum vitamin D levels. In addition, a reverse correlation was observed between number of cervical spinal cord plaques and serum vitamin D levels in spring. In autumn, there was a statistically significant relationship between number of brain plaque and serum vitamin D level. Additionally, a statistically significant relationship was found between serum vitamin D levels and number of plaques in winter. Our findings are in agreement with some previous studies that reported conflicting result, where the association of season with the prevalence of relapse cases cannot be verified. Although the mean serum levels of vitamin D are inversely correlated with the incidence of relapses in winter. However, the values obtained in the spring do not confirm such an inverse relationship.
ABSTRACT
Chronic kidney disease (CKD) is one of world health problems and its prevalence and incidence is increasing. Chronic Kidney Failure involves a range of pathophysiologic processes that are associated with impaired renal function, leading to cardiovascular morbidity and mortality. Renal artery resistive index (RI) is indicator of atherosclerotic change in small vessels. The current study was aimed to assess RI in diabetic nephropathy patients at stage 0-4 and to compare RRI with HbA1c, systolic blood pressure, diastolic blood pressure, albuminuria and glomerular filtration rate (GFR). In this cross sectional study,100 diabetic nephropathy patients who attend to nephrology clinic of Ali-ibn Abi Talib Hospital were entered to the study. Ultrasound Doppler renal resistive index was measured and other information was recorded from their last lab data that was recorded in their medical records. Variable included: systolic blood pressure, diastolic blood pressure, albuminuria, GFR, HbA1c. All data was analyzed by Pearson's Correlation Coefficient. The findings indicated a significant correlation of RI with systolic BP (p=0.04 R=0.75), microalbuminuria (P=0.001 R=0.67), and GFR (P=0.001 R=0.76), while diastolic BP (P=0/45 R=0/32), HbA1c (P=0/56 R=0/43) were not found to be associated with RI. The findings indicated that increased systolic blood pressure, albumin excretion (microalbuminuria) and severity of disease were capable of increasing RI values in diabetic nephropathy patients. In addition, decreased GFR.
