Abstract. The purpose of this study was to investigate the associations of tooth loss with skeletal bone mass, years since menopause, educational level, current smoking status, dietary calcium intake, and number of pregnancies in postmenopausal osteoporotic women in Turkey. The study population consisted of 1171 postmenopausal women aged 40–86 years (mean age, 61.19 ± 7.28 years). A detailed history was obtained from all women, including relevant lifestyle parameters, risk factors, and measurements of weight and height. Women were separated into three groups according to the number of teeth remaining as group 1 (edentulous, 457 women), group 2 (10 or fewer teeth, 232 women), and group 3 (more than 10 teeth remaining, 482 women). There was no significant difference among the three groups in mean age and menopausal age (P < 0.05). Body mass index of group 1 was significantly higher than that of group 2 (P < 0.01). Educational level was significantly different between three groups: groups 1 and 2 (P < 0.001), groups 1 and 3 (P < 0.0001), and groups 2 and 3 (P < 0.001). Educational level was lowest in group 1 and highest in group 3. Despite a low ratio of cigarette smoking in general, a smoking habit was most prevalent in group 3 and least in group 2. The ratio of women receiving adequate calcium was significantly lower in group 1 than in other groups (P < 0.001); mean calcium intake was similar in all groups. The number of pregnancies was significantly higher in group 1 than in other groups (P < 0.001). Lumbar bone mineral density (BMD) of group 1 was significantly lower than that of groups 2 and 3 (P < 0.001). Although no significant difference was found between groups 1 and 3, femoral neck BMD of group 2 was less than in others, and differences between groups 1 and 2 and between groups 2 and 3 (P < 0.001) were significant. Lumbar bone mineral content (BMC) of group 1 was significantly lower than that of groups 2 and 3 (P < 0.001), and lumbar BMC in group 2 was significantly higher than in group 3 (P < 0.05). Femoral neck BMC in group 1 was significantly higher than in groups 2 and 3 (P < 0.001). In conclusion, lumbar BMD and BMC in the edentulous group were significantly lower, whereas femoral neck BMD and BMC were significantly higher in edentulous group compared with the others. Our findings indicated that improvement in lifestyle factors and nutritional strategies for the treatment and prevention of osteoporosis may have additional benefit in reducing tooth loss.

The objective of this study was to determine and compare the quality of life (QOL) of patients with fibromyalgia syndrome (FS) and rheumatoid arthritis (RA) and to assess patients’ psychological and functional status in each group. This prospective study included 62 female FS patients and 60 female RA patients diagnosed by the American College of Rheumatology criteria. The Turkish translations of the Arthritis Impact Measurement Scale II (AIMS II) and Beck Depression Index (BDI) were given to all of the patients and they were asked to complete the two questionnaires. The scores of AIMS II, pain, and QOL were evaluated in the FS and RA groups. There were no statistically significant differences between the FS and RA groups (p>0.05) in terms of QOL. The affect subgroup scores of the AIMS II and BDI were highly correlated in the FS and RA groups (p<0.002, r=0.85 and p<0.05, r=0.80, respectively). The results show that the QOL is negatively but similarly affected in FS and RA groups.

Objective: The aim of this study is to show the effectiveness of high voltage galvanic stimulation [HVGS] in the treatment of trigger points [TrPs] in myofascial pain syndrome. Design: A placebo-controlled study. Setting: The study was performed in the physiotherapy unit of the Department of Physical Medicine and Rehabilitation in Marmara University Hospital. Patients: The patients formed three groups, one of them being the treatment group, the second placebo group, and a third being the control group who received exercise treatment only. Group A: HVGS+ exercise, Group B: Placebo HVGS +exercise, Group C: exercise only. Main Outcome Measure: Patients were evaluated before sessions, after the sessions, and 15 days after the treatment with the use of visual analog scale for pain, TrP tenderness index, analgesic use, and the patients general assessment. Result: At the end of the study pain levels decreased in patients of all three groups, but the decrease was more significant in HVGS group [P < 0.05]. Trigger point tenderness index was decreased significantly in the treatment group [P < 0.05]. Patients in the placebo group had the same complaints. Conclusions: We conclude that HVGS is effective in the treatment of tenderness in myofascial TrPs. Useful effects of HVGS continues in the midterm follow-up. High voltage galvanic stimulation can be accepted as a useful adjunctive modality in the treatment of myofascial TrPs.

Sympathetic skin response (SSR) and RR interval variation (RRIV) are used commonly for the assessment of sympathetic and parasympathetic nervous system function, respectively. We determined the normal values of SSR and RRIV in 23 (14 females, nine males) Turkish children aged 5 to 14 (mean 9.86, SD 2.48) years. SSR was recorded on the hands and feet during the electrical stimulation of both median and posterior tibial nerves, respectively. Similar response was elicited on both feet during the stimulation of the right median nerve. RRIV testing was performed during rest on the supine position and deep inspiration at a frequency of 6 times/min. The SSR was elicited in all children. The mean SSR latencies recorded on the feet during the stimulation of median or posterior tibial nerve were significantly more prolonged than those recorded at the hands (P < 0.001). There was no significant difference between the mean latencies of SSR recorded at the ipsilateral and contralateral palms or soles. The mean latencies recorded at the sole during stimulation of the median nerve were not significantly different compared to those that recorded at the sole during the posterior tibial nerve (P > 0.05). The SSR amplitudes were not assessed because of great variability and rapid habituation. The mean RRIV (46.54+/-11.29%) during deep breathing was significantly increased as compared to that (35.90+/-10.63%) during rest (P < 0.003). As a result, SSR and RRIV are preferred non-invasive tests for evaluation of autonomic nervous system in children. The SSR is useful and reliable if it is obtained in the optimum technical conditions. Further research is necessary to establish strict criteria for abnormality.

This study was performed on 30 patients who had undergone various gynaecological operations. Transcutaneous electrical nerve stimulation (TENS) was used on 17 patients and placebo TENS on the remaining 13. Pain severity, the need for analgesic drugs and the presence of paralytic ileus were evaluated in all patients during the first three postoperative days. There was no significant difference in pain severity between the two groups in the immediate postoperative period (p > 0.5). However, evaluations performed at the end of the first, second and third postoperative days revealed a very significant difference in pain severity (p < 0.01) and analgesic drug use in the two groups. A comparison of postoperative complications showed paralytic ileus in seven patients in the placebo group (54%); only two patients in the TENS group (12%) showed the same symptoms. Significant analgesia, an important reduction in analgesic drug use and a decrease in the incidence of paralytic ileus were observed as a result of the application of TENS in the postoperative period.

Hemochromatosis is a genetic disease related to human leukocyte antigen (HLA) A3, B7, and B14 histocompatability antigens resulting in increased iron absorption from the gastrointestinal tract and deposition of iron in tissues. Arthropathy is not uncommon in the late stage of disease. Characteristic radiologic findings are commonly observed in the wrists and metacarpophalangeal joints as well as the hips, knees, and ankle joints. Presented here is a 34-year-old male with hemochromatosis and bilateral shoulder, knee, and ankle pain. Radiologic examination revealed osteoarthritic findings in both ankle joints and chondrocalcinosis in the knee joints. All the major criteria of hypermobility syndrome were observed on physical examination. The early-onset arthropathy seen with this hemochromatosis is thought to result from hypermobility syndrome.

Abstract Purpose: To evaluate the effects of vest type dynamic elastomeric fabric orthosis on posture and balance during sitting and gross manual dexterity and to compare the efficacy of daily wearing time of 2 h versus 6 h. Method: Twenty-four children with cerebral palsy (CP) aged 3–9 years with GMFCS levels III and IV were randomised to either of three groups: (i) a control group who received only conventional exercise therapy, (ii) dynamic elastomeric fabric orthosis 2 h group who wore the orthosis for 2 h during therapy and dynamic elastomeric fabric orthosis 6 h group who wore the orthosis for 4 h in addition to the 2 h of wear along with therapy during hospital inpatient stay for 2 weeks. Children continued to use dynamic elastomeric fabric orthosis during the post-discharge period. The primary outcome measure was the Sitting Assessment Scale. The secondary outcome measurements were the sitting dimension of Gross Motor Function Measure, Box and Block Test and Parent Satisfaction Survey. Assessments were made before treatment, at post-treatment, at 1-month post-treatment, and at 3-months post-treatment. Sitting Assessment Scale and Box and Block Test were also assessed when immediately after wearing the orthosis. This trial is registered with Clinicaltrials.gov, under number NCT03191552. Results: All groups showed similar improvements except the control group which showed less improvement in Sitting Assessment Scale scores compared to the dynamic elastomeric fabric orthosis groups. Dynamic elastomeric fabric orthosis groups showed greater improvements compared to the control group in the Sitting Assessment Scale but not in the sitting dimension of Gross Motor Function Measure and Box and Block Test at post-treatment, at 1-month post-treatment and at 3-months post-treatment. When the dynamic elastomeric fabric orthosis groups (2 h versus 6 h) were compared, there were no significant differences in any of the assessments. The Sitting Assessment Scale and Box and Block Test scores also improved immediately after the patients put on the orthosis. At 1-month post-treatment, parents of children in the control group reported less satisfaction than parents of the children in dynamic elastomeric fabric orthosis groups. Conclusions: Dynamic elastomeric fabric orthosis vest has an immediate effect on the sitting balance and gross manual dexterity. It also provides improvements in posture and balance during sitting. Wearing dynamic elastomeric fabric orthosis vest for 2 h during therapy is as much effective as wearing it for 6 h in children with CP in addition to therapy to improve sitting balance. Implications for rehabilitation Dynamic elastomeric fabric orthosis vest provides improvements in sitting balance when used in addition to conventional therapy in children with cerebral palsy. Wearing dynamic elastomeric fabric orthosis for 2 h and wearing dynamic elastomeric fabric orthosis vest for 6 h resulted in similar clinical outcomes. Dynamic elastomeric fabric orthosis vest has an immediate effect on sitting balance and gross manual dexterity in children with cerebral palsy.

Objectives This study aims to estimate the prevalence of rheumatoid arthritis (RA) and spondyloarthritis (SpA) in Turkey using the same telephone questionnaire developed for screening RA and SpA in France and used in Serbia and Lithuania. Material and methods The study was performed in two steps. In step I, the French questionnaire was translated into Turkish and validated through a group of 200 patients (80 males, 120 females; mean age 44.0±13.1 years; range 19 to 75 years) followed up at the rheumatology departments of University Hospitals in Antalya and Ankara. In step II, the validated Turkish questionnaire was administered face-to-face to randomly selected 4,012 subjects (1,670 males, 2,342 females; mean age 41.5±16.8 years; range 16 to 97 years) by trained general practitioners across the country, in 25 prov- inces for case detection. The subjects who were suspected of having RA or SpA in accordance with the questionnaire were invited to the nearest university hospital for rheumatologic examination in order to confirm the diagnosis. Results In step II, a total of 25 subjects (2 males, 23 females) were diagnosed as RA. The standardized RA prevalence for the general population of Turkey was calculated as 0.56% (95% confidence interval [CI]; 0.33-0.79), 0.10% (95% CI; -0.05-0.25) for males and 0.89% (95% CI; 0.51-1.27) for females. A total of 18 subjects (3 males, 15 females) were diagnosed as SpA. The standardized SpA prevalence for the general population of Turkey was 0.46% (95% CI; 0.25-0.67), 0.17% (95% CI; -0.03-0.37) for males and 0.65% (95% CI; 0.32-0.98) for females. The prevalence of RA was highest in the Northern region (2.00%) and the prevalence of SpA was highest in the Central region (1.49%). Conclusion The prevalences of RA and SpA in Turkey are close to each other and there are significant inter-regional variations in prevalences of both RA and SpA.

BackgroundCystic fibrosis (CF) affects the musculoskeletal system via a multifactorial pathway that includes vitamin D deficiency and involvement of respiratory muscles such as intercostals due to recurrent upper and lower respiratory tract infections. Eventual result is the deterioration of musculoskeletal health and posture in CF patients. Postural stability is directly affected by posture and can be compromised in every musculoskeletal problem. The aim of this study is to evaluate musculoskeletal system and postural stability in patients with CF.MethodsPatients with CF over six years of age and age and sex-matched control groups were included in the study. Cobb angle and thoracic kyphosis angles were measured on the spine radiographs. Both patients and control group were examined with pediatric gait, arms, legs and spine scale (pGALS). They also were evaluated with a NeuroCom Balance Master for their postural stability.ResultsFifty-one patients with CF and 94 healthy controls participated in the study. In results of the pGALS examination, CF group had significantly more pathological findings than the control group in lower extremity appearance and movement (p = 0.006 and p = 0.01) and spine appearance and movement (p = 0.001 and p = 0.022) domains. The tandem walking speed was significantly higher in controls with a mean of 24.45 ± 7.79 while it was 20.47 ± 6.95 in the CF group (p = 0.03). Various limits of stability parameters also showed significant differences. Medium correlations were found between musculoskeletal examination and postural stability parameters.ConclusionIn patients with CF, a systematic but simple musculoskeletal examination can detect pathologies, which are more frequent than the normal population. These pathologies show a medium correlation with the involvement of postural stability.

Objective: To investigate the effects of kinesiology taping and different types of application techniques of kinesiology taping in addition to therapeutic exercises in the treatment of congenital muscular torticollis. Design: Prospective, single blind, randomized controlled trial. Setting: An outpatient rehabilitation clinic in a tertiary university hospital. Subjects: Infants with congenital muscular torticollis aged 3-12 months. Interventions: Group 1 included 11 infants who only received exercises, Group 2 included 12 infants who received kinesiology taping applied on the affected side by using inhibition technique in addition to exercises. Group 3 included 10 infants who additionally received kinesiology taping applied on the unaffected side by using facilitation technique and on the affected side by using inhibition technique. Main measures: Range of motion in lateral flexion and rotation of the neck, muscle function and degree of craniofacial changes were assessed at pretreatment, post treatment and, 1 month and 3 months’ post treatment. Results: Friedman analysis of within-group changes over time revealed significant differences for all of the outcome variables in all groups except cervical rotation in Group 3 (P<0.05). No significant differences were found between groups at any of the follow-up time points for any of the outcome variables (P>0.05). Conclusions: There is no any additive effect of kinesiology taping to exercises for the treatment of congenital muscular torticollis. Also different techniques of applying kinesiology taping resulted in similar clinical outcomes.
