STUDY DESIGN: A prospective, cross-sectional, non-randomized study. PURPOSE: To assess the effectiveness of intramuscular calcitonin injection in the treatment of lumbar spinal stenosis (LSS). OVERVIEW OF LITERATURE: LSS, manifesting as chronic low back pain and neurogenic claudication, is a chronic condition with an increasing incidence in the elderly population having inadequate effective conservative treatment options. METHODS: In this study, 36 patients with LSS who were diagnosed based on the clinical findings and magnetic resonance imaging were included. Patients received 100 IU of calcitonin per week for one month and were evaluated before and after treatment using the Oswestry disability index (ODI) questionnaire and visual analogue scale (VAS). Before treatment, the patients were divided into two subgroups based on their ODI results: patients with mild to moderate low back pain (disability, 0%-40%) and patients with severe or very severe low back pain (disability, 40%-100%). RESULTS: In patients with mild to moderate low back pain, there were no significant changes in the ODI and VAS after calcitonin injection. But in patients with severe or very severe low back pain, pain severity, personal functions, ability to lift and carry objects, time interval between standing and initiation of pain, social life, disability percentage, and VAS were significantly improved after treatment with calcitonin. CONCLUSIONS: It seems that an intramuscular injection of low dose of calcitonin may have some beneficial effects on the pain due to LSS, especially in patients who suffer from severe or very severe low back pain.

PURPOSE: We aimed to investigate the utility of sympathetic skin response (SSR) test for evaluating vasculogenic erectile dysfunction (ED) which is the most common type of impotence. MATERIALS AND METHODS: Men in the age group of 28 to 60 years and suffering from vasculogenic ED, as confirmed by a papaverin test and color Doppler sonography, at least for 6 months referred from our university urology department were included. We used the International Index of Erectile Function (IIEF-5) for grading severity of dysfunction and recorded the SSR of every patient from the median, tibial, and dorsal nerves of the penis. One-way analysis of variance (ANOVA), independent t-test and Pearson's correlation coefficient were used for comparing quantitative variables, and Fisher's Exact test was used for comparing qualitative variables. The Mann-Whitney U Test and the Kruskal-Wallis test were performed for analysis of data that were not normally distributed. A p value of less than 0.05 was considered significant. RESULTS: Forty-two patients were recruited for the study. We found a strong statistical relationship between the IIEF score and the pathologic SSR registered from every mentioned nerve. Patients with abnormal SSR had more severe ED according to IIEF score (p<0.001). In addition, the IIEF score had a significantcorrelation with diabetes mellitus and cardiovascular disease (t-test; p<0.05). CONCLUSIONS: Our results confirmed the presence of autonomic dysfunction in patients with vasculogenic impotence via an SSR test. We suggest evaluating the efficacy of the SSR test in patients with vascular impotence for treatment response monitoring in future studies.

STUDY DESIGN: A cross-sectional study. PURPOSE: To describe the correlation between lumbar lordosis angle and functional status of patients with chronic mechanical low back pain (CMLBP). OVERVIEW OF LITERATURE: There are different and conflicting opinions regarding the relationship between the degree of lumbar lordosis and functional status of patients with low back pain. Nonetheless, the severity of lordosis is still one of the routine physical exams considered in rehabilitation clinics. METHODS: The degree of lumbar lordosis of 150 patients with CMLBP was measured by means of Cobb's method using sagittal standing spinal radiographs. Subjects with probable secondary causes of low back pain (trauma, congenital anomaly, spinal infection, rheumatologic problems and history of spinal surgery) were excluded. Besides recording demographic data, their score of functional disability was estimated using Oswestry Disability Questionnaire, one of the most useful and reliable questionnaires. Comparison between these data was made regarding different age and gender groups. RESULTS: In this study, 119 subjects were female and 31 male, with an age range of 19-85 years. The average degree of lumbar lordosis was 44.69+/-11.43 and that of Oswestry disability index (ODI) 30.52%. Although we found a significant direct relationship between age and degree of lumbar lordosis (Pearson's correlation coefficient, p=0.016, r=0.197), while insignificant correlation was seen between the degree of lumbar lordosis and ODI (p=0.129). CONCLUSIONS: There was no significant correlation between the degree of lumbar lordosis and the score of functional disability with regards to different age groups and gender.
