ABSTRACT: This study aimed to investigate the predictive role of grip strength on bone mineral density (BMD) of different sites in males.
Two hundred thirty-four male patients were included in the study. BMD of lumbar spine, femoral neck, proximal radius-ulna
(PRU) and distal radius-ulna (DRU) sites were measured by dual-energy X-ray absorptiometry and grip strength by using a hand
dynamometer. Grip strength and BMD values of PRU and DRU at forearms were significantly higher on the dominant sides (P=0.001, P=0.001, P=0.001, respectively). Stepwise linear regression analysis revealed that only the grip strength of the same side was the
best predictor of the BMD of the dominant and non-dominant PRU with a ratio of 8.5 and 10.2%, respectively, whereas grip strength
of the same side, age and weight were the best predictors of the BMD of the dominant and non-dominant DRU with a ratio of
25 and 24.6%, respectively. There was no predictive value of grip strength for BMD of lumbar spine and femoral neck. In conclusion,
grip strength appears to be predictive of site specific rather than systemic BMD.

ABSTRACT: The aim of this study was to investigate the presence of autonomic dysfunction in patients with osteoporosis.
This is a prospective controlled trial. Sixteen postmenopausal female patients with osteoporosis and 10 age-matched postmenopausal nonosteoporotic controls were included in the study. Participants were divided into the postmenopausal osteoporosis group and the nonosteoporotic control group according to bone mineral densities. Heart rate variability parameters and sympathetic skin responses were studied to evaluate autonomic functions.
The latencies of sympathetic skin responses obtained from both hands were significantly increased in the patient group when compared with the control group. The sympathetic skin response amplitude of the right hands and both feet of the patient group were found to be decreased significantly when compared with that of the control group. A 24-hr high-frequency value was significantly decreased in the patient group than in control group. A 24-hr low-/high-frequency value was significantly higher in the patient group than in the control group.
Autonomic dysfunction characterized with increased sympathetic and decreased parasympathetic activity may be present in osteoporosis, and cardiac functions in patients with osteoporosis may also be affected by accompanying autonomic dysfunction.

ABSTRACT: The aim of this study is to investigate the effects of ovariectomy on bone mineral density (BMD) and oxidative state in rats, and the alterations in these effects that vitamin C supplementation may produce.
TWENTY FEMALE WISTAR ALBINO RATS WERE RANDOMLY DIVIDED INTO THREE GROUPS: control (C, n=6); ovariectomy (O, n=7); and ovariectomy+vitamin C supplement (OV, n=7). Oxidative stress (OS) was assessed 100 days postovariectomy by measuring the activity of several enzymes, including catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase, as well as the concentrations of malondialdehyde (MDA), nitric oxide (NO), and total sulfhydryl groups in plasma and bone homogenates.
A significant decrease in BMD was observed in O group compared with C group (p=0.015), and a significant increase was observed in OV compared with O group (p=0.003). When groups were compared with respect to parameters of OS, MDA and NO levels in bone tissue were significantly higher in O than in C (p=0.032, p=0.022) and were significantly lower in OV than in O (p=0.025, p=0.018). SOD activity was significantly higher in O than in C (p=0.032). In plasma, MDA activity was significantly higher in O than in C (p=0.022) and NO level was significantly higher in O than in C and OV (p=0.017, p=0.018).
Our results suggest that ovariectomy may produce osteoporosis and OS in females, and vitamin C supplementation may provide alterations regarding improvement in OS and BMD values. We assume that studies including more subjects are needed to make a decisive conclusion about OS-BMD relation.

ABSTRACT: In this study, in 131 men aged 20-75 years, we investigated correlations between bone mineral density (BMD) in the lumbar spine and femoral neck and endogenous factors (age, body mass index) as well as exogenous factors (calcium intake, physical activity, smoking, caffeine, socioeconomic and educational levels). The age had a negative effect on femoral neck BMD in patients overall, and on both lumbar spine and femoral neck BMD in patients under 50. Physical activity has effects on femoral neck BMD in men above 50. Lumbar vertebral BMD negatively correlated with smoking in patients overall, and this correlation persisted when patients aged 50 and older were analyzed separately. Femoral neck BMD was positively correlated with body mass index in men aged 50 and older. Given the variety of findings in the research literature regarding risk factors for low BMD, we suggest that genetic and geographic factors should be considered.

ABSTRACT: Inguinoscrotal pathologies are commonly seen in childhood. The genitofemoral nerve (GFN) is responsible for sensitive innervations of scrotal region and the motor innervations of cremasteric muscle. GFN also innervates the afferent and efferent pathways of cremasteric reflex. A prospective study was performed to evaluate the possible relation between inguinoscrotal pathologies and GFN motor functions.
Patients with inguinal hernia, hydrocele, undescended or retractile testicles, aged between 2-12 years were enrolled in the study. Bilateral latency and duration of GFN motor conductions (GFNMC) were obtained electrophysiologically by surface electrodes. GFNMC recordings of non-pathological sides were assessed as control group. Latency and duration of each group were compared with control group (Mann-Whitney U test). P values lower than .05 were considered significant.
Seventy-three electrophysiologic evaluations were investigated in inguinal hernia (n:18), hydrocele (n:9), undescended testicle (n:14), retractile testicle (n:12) and control (n:20) groups. There was no age difference between groups and controls. Latency was significantly prolonged in inguinal hernia group when compared with control group (P = .028). Although the latencies were shortened in undescended testicle group, no significant difference detected (P > .05).
Prolonged latencies in inguinal hernia may be a result of nerve trap caused by hernia sac. GFN motor functions showed no causative role in other inguinoscrotal pathologies. It can be also suggested that clinical features of other inguinoscrotal pathologies were not affected by GFN motor functions. Electrophysiological studies in younger age groups with large number of patients are needed to support our suggestions.

ABSTRACT: To evaluate the possible relationship between the sexual and psychiatric status of premenopausal female patients with fibromyalgia compared with healthy controls.
A total of 48 female patients with fibromyalgia and 38 age-matched healthy controls were enrolled in the study. All the subjects were asked to complete the Female Sexual Function Index (FSFI) for sexual status and the State-Trait Anxiety Inventory (STAI) and Beck Depression Inventory (BDI) for psychiatric assessment. Serum biochemical analysis was done, and the serum hormonal levels were analyzed.
The mean BDI score for patients was significantly greater than the score for the controls (P = 0.017) and the mean FSFI score was significantly lower than the score for the controls (P = 0.001). According to the FSFI data, female sexual dysfunction was found in 26 patients (54.2%) with fibromyalgia and only 6 controls (15.8%), a significant difference (Pearson chi-square = 14.46, P = 0.000). When the subscores of each domain of FSFI were evaluated, the most common sexual problem was diminished desire in patients (n = 30, 62.5%) and controls (n = 11, 28.9%). In the correlation analysis, the FSFI score showed a significant negative correlation with the BDI (r = -0.337, P = 0.002) and STAI (r = -0.413, P = 0.004) scores. No significant correlation was revealed between the FSFI and BDI or FSFI and STAI scores in the controls.
Depression is one of the emotional disorders commonly encountered in women with fibromyalgia, most possibly leading to sexual dysfunction. Thus, sexual dysfunction related to impaired psychiatric status should be considered a common problem in premenopausal women with fibromyalgia.

ABSTRACT: To evaluate the role of endogenous sex steroids on bone mineral density (BMD) in healthy Turkish men.
Serum total testosterone (TT), free testosterone (FT), dehydroepiandrosterone sulfate and estradiol levels were assayed in 174 healthy men of 240 volunteers, aged 22-76 years. Dual-energy X-ray absorptiometry was used to measure the BMD (g/cm(2)) of lumbar spine, femoral neck and non-dominant proximal and distal radius-ulna sites. Linear regressions were conducted using each BMD site as the dependent variable and each sex steroid as the independent variable. Four models were run for each bone site and sex steroid; crude, age-adjusted, adjusted for age and body mass index (BMI), and adjusted for age, BMI and cigarette-smoking.
The mean age and BMI of men enrolled in the study were 47.7 +/- 13.7 years and 26.9 +/- 3.6 kg/m(2). Log of FT was significantly associated with the BMD of distal forearm in all models analyzing the crude and adjusted effects. Dehydroepiandrosterone sulfate effect on BMD of proximal forearm came closer to the level of statistical significance when adjusted with age, BMI and cigarette-smoking. Estradiol and TT levels were not found to be associated with BMD of any sites measured.
Among the endogenous sex steroids in men, predominantly FT seems to be one of the determinants of BMD. Therefore a decrease in serum levels of testosterone in aging male or secondary causes may negatively affect BMD.

ABSTRACT: To determine the relationship between the total and subscale scores of the Aging Male Symptoms (AMS) and International Index of Erectile Function (IIEF) questionnaires, age, and serum sex steroids levels.
A total of 348 patients enrolled in the study answered the AMS and IIEF questionnaires. Hormonal analysis, including total testosterone, free testosterone (FT), estradiol (E2), and dehydroepiandrosterone-sulphate (DHEA-S) measurement, were performed. The patients with a total AMS score of 29 were considered to have aging male symptoms and the patients with an IIEF score of less than 26 were considered to have sexual dysfunction.
Although DHEA-S levels were significantly lower and E2 levels were greater in the men with aging male symptoms according to the AMS, the DHEA-S and FT levels were significantly lower in the men with sexual dysfunction, as determined by the IIEF score. Serum DHEA-S and FT levels and age correlated significantly with the IIEF scores. The total AMS score correlated significantly only with age. Although serum total testosterone, FT, and DHEA-S levels correlated significantly with the andrologic symptoms of AMS, the serum E2 levels correlated with psychological symptoms of AMS.
Although aging male symptoms and the effects of hormonal changes on these symptoms have been controversial, DHEA-S and E2 might play some important roles in the symptoms of aging men.

ABSTRACT: Clinical and electrophysiologic comparison of the efficacy of transcutaneous electrical nerve stimulation (TENS) and oral baclofen in the treatment of spasticity.
Patients with spinal cord injury and spasticity were included in the study. Ten patients were assigned to oral baclofen and 11 to TENS groups. For the comparison of H-reflex variables, 20 healthy individuals were allocated to a control group. TENS was applied to the tibial nerve for 15 days at a frequency of 100 Hz. Clinical (spasm frequency scale, painful spasm scale, lower limb Ashworth score, clonus score, deep tendon reflex score, plantar stimulation response score) and electrophysiologic evaluations (H-reflex response at the highest amplitude, latency of maximum H-reflex, and ratio of H-reflex response at the highest amplitude to M response at maximum amplitude) of the lower limb and functional evaluations (functional disability score and FIM) were carried out in baclofen and TENS groups before and after treatment. Posttreatment evaluation was made 24 hrs after the 15th session in the TENS group. In addition, clinical spasticity scores and electrophysiologic variables were measured 15 mins after the first application and 15 mins after the 15th session.
Significant improvement was detected in lower limb Ashworth score, spasm frequency scale, deep tendon reflex score, functional disability score, and FIM in the baclofen (P = 0.011, P = 0.014, P = 0.025, P = 0.004, and P = 0.005, respectively) and TENS (P = 0.020, P = 0.014, P = 0.025, P = 0.003, and P = 0.003, respectively) group after treatment. Decrease in H-reflex maximum amplitude was significant in the TENS group (P = 0.026). Most marked improvement was observed in the third evaluation, 15 mins after the 15th session, particularly in lower limb Ashworth score (P = 0.006) and H-reflex maximum amplitude (P = 0.006) in the TENS group. The percentage change in clinical, electrophysiologic, and functional variables caused by baclofen was not different from that caused by repeated applications of TENS in the short- and long-term evaluations (P > 0.05).
TENS may be recommended as a supplement to medical treatment in the management of spasticity.

ABSTRACT: To evaluate the diagnostic value of ultrasonography in patients with electrophysiologically confirmed carpal tunnel syndrome.
A prospective ultrasonographic study of 35 wrists with electrophysiologically confirmed carpal tunnel syndrome and of 40 normal wrists. Receiver-operating-characteristics curves for the ultrasonographic measurements of median nerve were plotted to identify the most optimal cutoff values.
The ultrasonographic measurements of median nerves were found to be increased significantly in patients with carpal tunnel syndrome when compared with controls, particularly in terms of cross-sectional area (P<0.001) and the bowing of the flexor retinaculum (P<0.01) but not in the flattening ratio (P>0.05). According to receiver-operating-characteristics curve results, the most optimal cutoff value for the cross-sectional area of the median nerve was obtained at the level of middle carpal tunnel, which was 9.3 mm, with a sensitivity of 80% and specificity of 77.5%. The optimal cutoff value for the bowing of the flexor retinaculum was 3.7 mm, with a sensitivity of 71.4% and specificity of 55%. No optimum cutoff value could be identified from the receiver-operating-characteristics curves for the flattening ratio of median nerve.
Ultrasonographic examination of the median nerve seems to be a promising method in the diagnosis of carpal tunnel syndrome, evaluating the morphologic changes of the median nerve in patients with clinical signs and symptoms. Further studies with wider series are needed to confirm our preliminary results.

ABSTRACT: Osteoarticular tuberculosis is a quite uncommon form of extrapulmonary tuberculosis. Difficulties in diagnosis often lead to delayed treatment, sometimes with devastating consequences for patients. We report herein a case of multifocal osteoarticular tuberculosis of insidious onset with no history of prior health problems or constitutional signs and symptoms. Despite widespread osteoarticular involvement, the outcome of the patient was favorable after the management. Osteoarticular tuberculosis must be considered in patients with insidious musculoskeletal symptomatology.

ABSTRACT: Osteoporosis is less common in obese individuals with increased bone mineral density (BMD) and plasma leptin concentrations. The aim of this study was to determine the correlation between leptin levels and BMD in postmenopausal women. The study consisted of 90 postmenopausal women with a mean age of 53.45 +/- 0.87 years who visited our outpatient clinic for the evaluation of BMD. Thirty-six post-menopausal women with osteoporosis (mean age: 54.52 +/- 1.41 years and mean body mass index (BMI, kg/m2) 29.33 +/- 0.66), 30 age- and BMI-matched postmenopausal women with normal BMD, and 24 postmenopausal women (mean age: 52.79 +/- 1.48 years and mean BMI: 29.45 +/- 0.89) with osteopenic BMD were included in the study. Plasma concentrations of leptin after an overnight fast were measured by radioimmunoassay. BMD values were measured by dual-energy X-ray absorptiometry (DEXA) at the L2-L4 lumbar spine and femoral neck. The median spine BMD value in the patient group (0.67 +/- 0.08 g/cm2, mean +/- SEM) was significantly lower than that in the control group (1.02 +/- 0.25 g/cm2, mean +/- SEM) and osteopenic group (0.87 +/- 0.05 g/cm2, mean +/- SEM) (p < 0.005). The mean spine BMD value (T score -3.63 +/- 0.25, mean +/- SEM) and the mean femur neck BMD value (T score -2.55 +/- 0.18, mean +/- SEM) of the osteoporosis group were significantly lower than that in the normal BMD group (+ 0.33 +/- 0.14 and + 0.27 +/- 0.18, P < 0.001) and in the osteopenia group (-1.74 +/- 0,1 and -1.18 +/- 0.05, p < 0.005). The mean plasma leptin concentration in the osteoporotic group (17.03 +/- 1.40 ng/ml) was not significantly different from that in the normal BMD group and the osteopenia group (16.55 +/- 1.50 ng/ml; 16.16 +/- 1.60, respectively, p > 0.150). Plasma leptin concentrations were correlated with BMI in three groups (r(s) = 0.450, p = 0.025 in normal BMD group and r(s) = 0.4254, P = 0.009 in the osteoporotic group, and r(s) = 395, p = 0.015 in the osteopenia group. There was no correlation between plasma leptin concentrations and BMD values in three groups (r(s) = -0.89 in normal BMD group, r(s) = -0.124 in osteopenia group, and r(s) = -0.195 in osteoporosis group). From this study we conclude that circulating plasma leptin does not have a significant direct influence on bone mass in postmenopausal women.

ABSTRACT: The cricoarytenoid (CA) joint involvement in rheumatoid arthritis (RA) is not uncommon. In this study, clinical assessment, laryngeal endoscopy, and high-resolution computed tomography (HRCT) were used in 15 patients with RA to evaluate the diagnostic criteria of CA joint involvement. Symptoms owing to CA joint involvement were present in 66.6% of the patients. The frequency of involvement was 13.3% on laryngeal endoscopy but 80.0% with HRCT assessment. The most common HRCT findings were CA prominence (46.6%), density and volume changes (46.6%), and CA subluxation (39.9%). In some of the patients, soft tissue swelling (20%) near the CA joint and narrowing in the piriform sinus (33.3%) were also observed. Radiologic abnormalities related to CA joint involvement generally precede clinical symptomatology. Therefore, HRCT evaluation may be a useful method in the assessment of CA joint involvement in RA patients to exclude possible causes of laryngeal signs and symptoms.

ABSTRACT: We aimed to compare the symptoms and signs of patients with temporomandibular disorders (TMD) with and without a history of diurnal teeth clenching.
The study was designed prospectively and included 34 patients with a diagnosis of bilateral temporomandibular joint pain and/or dysfunction. A "Patient Questionnaire Form" and "Patient Assessment Form" generated by the Diagnosis and Treatment Unit of Temporomandibular Disorders, Istanbul Medical Faculty, Istanbul University, were used in the evaluation of the patients.
The mean ages of patients with (group I, n=17) and without (group II, n=17) teeth clenching habit were 28.6+/-10.6 and 31.5+/-13.8 years, respectively. Female patients accounted for 76.5% and 47.1% in group I and group II, respectively. The age and gender showed no significant difference between the two groups (p>0.05). Stress factor was significantly higher in group I and was found to aggravate pain and other complaints, according to the questionnaire (p<0.05). Pain associated with jaw movements of all directions and pain radiating to the ear region were found to be significantly higher in group I (p<0.05). Total palpation index, based on physical examination of bilateral extra- and intra-oral masticatory muscles, neck muscles, and capsule of the temporomandibular joints was significantly higher in group I (p<0.05).
Our findings indicate that habit of teeth clenching in patients with TMD affects biomechanically both muscles and joints of the masticatory system, resulting in muscle/joint pain, and that stress factor aggravates those symptoms. This finding may be useful in the treatment of symptoms and signs of patients with TMD.

ABSTRACT: Temporomandibular joint (TMJ) involvement in rheumatoid arthritis (RA) is not uncommon. In this study a questionnaire, clinical assessment, and high resolution computerized tomography (HRCT) were used in 15 patients with rheumatoid arthritis to evaluate the diagnostic criteria of TMJ involvement. Symptoms due to TMJ involvement were present in 33.3% of the patients. Frequency of involvement was 40.0% on clinical assessment but 86.6% with HRCT assessment. The most common HRCT findings were decreases in the joint space (33.3%), mandibular subchondral cysts (23.3%), temporal subchondral cysts (23.3%), degeneration (23.3%), shape (13.3%) and height (13.3%) anomalies of the mandibular condyle, condylar head resorption (13.3%), erosion of the mandibular condyle (13.3%), and demineralization (13.3%). All patients with positive clinical findings also had positive HRCT findings. In seven (46.7%) of the patients, there were no symptoms or clinical findings implying TMJ involvement; however, they had positive results on HRCT evaluation. The HRCT findings may be the initial sign of TMJ involvement in patients with rheumatoid arthritis. In conclusion, it is suggested that RA patients with the suspicion of TMJ involvement should undergo HRCT evaluation, because HRCT findings may precede the clinical findings.
