Assessment of changes in penile sensation by electrophysiological study after radical prostatectomy: A pilot study.

BACKGROUND: To evaluate the changes in penile sensation by electrophysiological tests in patients who underwent radical prostatectomy (RP) and to demonstrate the role of dorsal penile nerve injury in postoperative erectile dysfunction. MATERIALS AND METHODS: Twenty-six volunteer patients who were eligible for RP were included in the study. Preoperative penile sensory electromyography and the International Index of Erectile Function-5 (IIEF-5) questionnaire were done for each patient. Erectile function assessment and electrophysiological evaluation of penile sensation were repeated at postoperative 3rd and 6th months. RESULTS: Postoperative IIEF-5 scores and electromyography values were significantly lower than preoperative findings (p < 0.05). The IIEF-5 scores in the nerve sparing-RP (NS-RP) group were significantly higher than the non-nerve sparing-RP (NNS-RP) group in the postoperative period. Nerve conduction velocity values in the NS-RP group were also higher than the NNS-RP group at the postoperative 3rd and 6th months. However, these changes were not statistically significant (p > 0.05). CONCLUSIONS: Patients who underwent RP have decreased penile sensation due to cavernous nerve damage and a possible dorsal penile nerve injury. The decrease of penile sensation may be associated with postoperative erectile dysfunction.

Effects of lumbar lordosis increment on gait deteriorations in ambulant boys with Duchenne Muscular Dystrophy: A cross-sectional study.

BACKGROUND: Increment of lumbar lordosis, a frequent spinal finding in Duchenne Muscular Dystrophy (DMD), is a compensatory mechanism secondary to muscle weakness. However, excessive lumbar lordosis may change the position of the center of mass, and lead to balance and walking difficulties. OBJECTIVE: To study the relationship between factors that may influence ambulatory function in boys with DMD and to investigate the effects of lumbar lordosis increment on gait and balance perturbations. METHODS: Twenty-one ambulant patients with DMD and 10 healthy boys were included. Lumbar lordosis and thoracic kyphosis angles, dynamic and static balance tests, ambulatory function, muscle strength, and disease severity were assessed. Usage of steroids and orthotic devices were recorded. Scoliosis was assessed on radiographs. Receiver operator characteristic curves were formed and area under curve (AUC) measurements were performed to assess the ability of the tests to discriminate ambulatory status and optimal cut-off values were established according to the Youden index. RESULTS: The amount of lumbar lordosis correlated strongly and negatively with quality of ambulation (r = -0.710) and moderately with performance on balance tests. The strength of both upper limbs and lower limbs muscles were not associated with any of the variables. According to the AUC analysis, patients with a lumbar lordosis higher than 36° had worse scores on gait and dynamic balance tests. CONCLUSION: Ambulation and dynamic balance are negatively affected by the increment of lumbar lordosis with a cut-off point of 36°in boys with DMD.

Mechanical Traction for Lumbar Radicular Pain: Supine or Prone? A Randomized Controlled Trial.

OBJECTIVE: The aim of the study was to compare the effects of mechanical lumbar traction either in the supine or in the prone position with conventional physical therapy (PT) in patients with chronic low back pain and lumbosacral nerve root involvement in terms of disability, pain, and mobility. DESIGN: Participants (N = 125) were randomly assigned to receive 15 sessions of PT with additional mechanical lumbar traction either in the supine position (supine traction group) or in the prone position (prone traction group) or only PT without traction (PT only group). Patients were assessed at baseline and at the end of the PT sessions in terms of disability, pain, and mobility. Disability was assessed using the modified Oswesty Disability Index; pain was assessed using a visual analog scale, and lumbar mobility was assessed using the modified lumbar Schober test. RESULTS: One hundred eighteen patients completed the trial. All groups improved significantly in the Oswesty Disability Index, visual analog scale, and modified lumbar Schober test (P < 0.05). In the between-group analysis, improvements of Oswesty Disability Index and visual analog scale were found significantly better in the prone traction group compared with the PT only group (adjusted P = 0.031 and 0.006, respectively). CONCLUSIONS: Addition of traction in the prone position to other modalities resulted in larger immediate improvements in terms of pain and disability, and the results suggest that when using traction, prone traction might be first choice. Further research is needed to confirm the benefits of lumbar traction in the prone position.

Restless legs syndrome in children with allergic rhinitis: A comparative study on frequency, severity and sleep quality.

OBJECTIVES: This study aims to investigate the frequency and severity of restless legs syndrome (RLS) and its relationship with sleep quality in children with allergic rhinitis (AR) with the hypothesis that comorbid RLS may be an additional causative factor of sleep disturbances in pediatric AR. PATIENTS AND METHODS: A total of 143 children with AR (aged 8-18 years) and 144 healthy control subjects (aged 8-18 years) were included. The diagnosis of AR was established on history, clinical examination and skin prick test according to the Allergic Rhinitis and its Impact on Asthma guidelines. Presence of RLS was determined using the International RLS study group (IRLSSG) criteria. The severity of RLS was assessed using the IRLSSG rating scale. Sleep quality was evaluated by Pittsburgh Sleep Quality Index (PSQI). RESULTS: Thirteen patients (9.1%) in AR group, and six children (4.2%) in control group had RLS (p=0.159). The frequency of RLS in AR group was higher than two folds when compared to the control group; however, the difference was not statistically significant. Restless legs syndrome severity score was significantly higher in AR group than control group (15.00 [11-20] and 11.00 [10-16] respectively, p=0.046). Total PSQI scores were similar between groups. Also, no significant differences were observed in total PSQI scores of AR patients with or without RLS. CONCLUSION: Restless legs syndrome was not more common but was more severe in children with AR. There was no evidence that RLS has an obvious effect on sleep quality in children with AR.

Electroneuromyographic findings in pseudoexfoliation syndrome.

PURPOSE: To examine peripheral electroneuromyographic findings in patients with ocular pseudoexfoliation syndrome (PEX) and to compare them controls without PEX. METHODS: A case-control study design was used to examine 31 patients with PEX and compare the findings with those of 31 age- and sex-matched healthy controls. All patients underwent complete ophthalmologic examination that included peripheral electroneuromyography examination. Motor and sensorial nerve conduction of the median, ulnar, tibial, peroneal, and sural nerve and the sympathetic skin response were measured. RESULTS: The average sensorial nerve latency of the ulnar and sural nerve was significantly longer in the PEX group compared to the control group (p < 0.05). The average sensorial nerve conduction amplitude and the velocity of the ulnar and sural nerve were significantly lower in the PEX group (p < 0.05). DISCUSSION: Peripheral nerves, especially sensorial fibers, appear to be affected in PEX patients. These finding may indicate that PEX is a systemic disease.

Late-onset Hirayama disease presenting with ulnar neuropathy: A case report.

Hirayama disease (HD) was first reported by Hirayama et al. in 1959. The disease is considered as a type of benign focal motor neuron disease that primarily affects upper limbs of young males. In this case report, we present a man aged 40-years with rapidly progressive weakness and atrophy in his left hand. The findings of nerve conduction studies were consistent with left ulnar neuropathy at the elbow. Flexion magnetic resonance imaging (MRI) revealed minimal enlargement of the posterior epidural space and anterior displacement of the spinal cord. After exclusion of relevant diseases the patient was diagnosed as having Hirayama disease with ulnar neuropathy. Mild ulnar entrapment at the elbow may be considered as a clinical feature of HD. Therefore, it is recommended that young male patients with wasting in upper extremities with findings of ulnar entrapment should not be judged to have ulnar neuropathy before HD has been carefully excluded.

The effectiveness of transcutaneous electrical nerve stimulation in the management of patients with complex regional pain syndrome: A randomized, double-blinded, placebo-controlled prospective study.

OBJECTIVE: To investigate the effect of transcutaneous electrical nerve stimulation (TENS) on clinical recovery in the management of patients with complex regional pain syndrome Type I (CRPS Type I). MATERIAL AND METHOD: The study included 30 patients with stage 1 and 2 CRPS Type I in the upper extremities. The patients were randomly assigned into 2 groups, group 1 (n= 15) received conventional TENS therapy for 20 minutes, and group 2 (n= 15) received sham TENS therapy. The standard physical therapy program, which included contrast bath for 20 minutes; whirlpool bath for 15 minutes; assisted active and passive range of motion, and static stretching exercises up to the pain threshold, was also conducted in both groups. Therapy was scheduled for 15 sessions. A visual analogue scale (VAS) was used to assess spontaneous pain. The Leeds Assessment of Neuropathic Signs and Symptoms (LANSS) scale and the Douleur Neuropathique en 4 Questions (DN-4) were used to assess neuropathic pain. In addition, range of motion (ROM) was measured using a goniometer and volumetric measurements were taken to assess edema. Functional capacity was assessed using a hand dynamometer and the Duruöz Hand Index (DHI). All measurements were performed at baseline and after therapy. RESULTS: Significant improvements were achieved in spontaneous and neuropathic pain scores, edema, ROM, and functional capacity in both groups (p< 0.05). However, improvement was found to be significantly greater in group 1 regarding pain intensity, neuropathic pain assessed using LANNS, edema, and in the 2nd-3rd finger ROM measurements (p< 0.05). No significant difference was detected between groups regarding improvements in 4th-5th finger and wrist ROM measurements, grip strength, and DN4 and DHI scores (p> 0.05). CONCLUSION: The addition of TENS to the physical therapy program was seen to make a significant contribution to clinical recovery in CRPS Type 1.

Comparison of efficacy of kinesiological taping and subacromial injection therapy in subacromial impingement syndrome.

The aim of the study was to compare the efficacy of kinesiological taping and subacromial injection therapy in patients with subacromial impingement syndrome (SIS). Seventy patients diagnosed with SIS were randomly assigned to group 1 (n = 35, injection group) or group 2 (n = 35, kinesiological taping group). Betamethasone plus prilocaine was injected to subacromial space in the patients in group 1. In group 2, tape was applied three times for a period of five consecutive days with a 2-day recovery interval. A 3-month exercise program was prescribed for both groups including stretching and strengthening exercises. All patients were assessed at baseline and at 1 and 3 months post-intervention. Assessments were made by visual analog scale (VAS) for pain, range of motion (ROM) measurements, specific tests, and Shoulder Pain and Disability Index (SPADI). Significant differences were detected in VAS and SPADI scores as well as ROM measurements in both groups when compared to baseline (p > 0.05). No significant differences were detected between the groups except for active flexion degree in favor of group 1 (p = 0.004). Both kinesiological taping and steroid injection in conjunction with an exercise program were found to be effective in the treatment of SIS. Kinesio taping may be an alternative treatment option in the rehabilitation of SIS especially when a non-invasive technique is needed.

An evaluation of sleep quality and the prevalence of restless leg syndrome in vitamin D deficiency.

Vitamin D is known to increase levels of dopamine and its metabolites in the brain and also protects dopaminergic neurons against dopaminergic toxins. The aims of the study were to assess the frequency and symptom severity of restless leg syndrome (RLS) and sleep quality in vitamin D deficiency. A total of 102 patients were enrolled in this cross-sectional study, comprising 57 vitamin D deficient patients as Group 1 and 45 patients with normal levels of vitamin D as Group 2. RLS was diagnosed according to the International RLS Study Group (IRLSSG) diagnostic criteria. Symptom severity was assessed using the IRLSSG rating scale and sleep quality was measured with the Pittsburgh sleep quality index (PSQI). RLS incidence was higher in Group 1 (p = 0.034). The PSQI scores were higher in Group 1 and the difference between the groups was determined as statistically significant (p < 0.05). No statistically significant difference was determined in respect of the clinical evaluation and the IRLSSG Symptom Severity Scale between the patients in Group 1 diagnosed with RLS and the patients in Group 2 diagnosed with RLS (p > 0.05). The findings of this study support the hypothesis that RLS is more frequent and more severe in vitamin D deficiency and indicate a negative effect of vitamin deficiency on sleep parameters.

Investigation of the H reflexes, F waves and sympathetic skin response with electromyography (EMG) in patients with stroke and the determination of the relationship with functional capacity.

The purpose of the study was to evaluate the relationship between sympathetic skin responses (SSR), electrodiagnostic reflex activities (F wave, H reflex), and functional capacity in post-stroke patients. The study comprised 40 hemiplegia patients (mean age 57.8 ± 10.9 years) and 40 healthy volunteers (mean age 557 ± 85 years). In electrophysiological studies, SSR, F wave and H reflex were evaluated and for the functional capacities of patients, FIM scores and Brunnstrom stages were calculated. There was no statistical significant difference between SSR latency and amplitude in the hemiplegic and non-hemiplegic extremities of patients (p > 0.05). SSR latency values of patients were higher than those of controls (p < 0.05). Amplitude values of paretic arms were significantly lower than the control group extremities (p < 0.05). There was a significant correlation between SSR amplitude values and FIM scores. A significant increase in H max/M max amplitude rate was detected in the affected side (p < 0.05) and F-wave mean latency values of the affected side were found to be significantly lower in the control group (p < 0.05).

Cardiac autonomic function in patients with rheumatoid arthritis: heart rate turbulence analysis.

OBJECTIVE: Rheumatoid arthritis (RA) is a chronic systemic disease. The risk of cardiovascular morbidity and mortality is high in patients with RA. Heart rate turbulence (HRT) expresses ventriculophasic sinus arrhythmia and has been considered to reflect cardiac autonomic activity. It has been shown that HRT is an independent and powerful predictor of mortality. The aim of this study is to determine if HRT changes in patients with RA in comparison with the healthy controls. METHODS: The study was performed as a cross-sectional study. Twenty-six patients with RA (mean age 56 ± 10 years, 18 women) and 26 healthy controls (mean age 55 ± 9 years, 18 women) were enrolled in this study. All participants underwent 24 hours Holter electrocardiogram monitoring. HRT measurements, turbulence onset (TO) and turbulence slope (TS), were calculated in patients and healthy controls that have at least one ventricular premature complex (VPC) in their Holter recordings. TO is a measure of the early sinus acceleration and TS is the measure of the rate of sinus deceleration that follows the sinus acceleration after a VPC. Mann-Whitney U test was used for comparison of continuous variables and the Chi-square test for comparison of categorical variables. RESULTS: There were no statistically significant differences in TO and TS between the RA and control groups (TO: -2.2 ± 3.1% vs -2.8 ± 2.5%, p=0.25; TS: 11.5 ± 9.7 ms/RR vs 15.5 ± 10.9 ms/RR, p=0.10). CONCLUSION: HRT parameters, which determine the autonomic dysfunction, did not seem to be altered in patients with RA.

Evidence of association of vitamin D receptor Apa I gene polymorphism with bone mineral density in postmenopausal women with osteoporosis.

The vitamin D receptor (VDR) was the first candidate gene to be studied in relation to osteoporosis, and most attention has focused on polymorphisms situated near the 3' flank of VDR. The aim of this study was to investigate the association about VDR gene Apa I polymorphism with bone mineral density (BMD) in postmenopausal women with osteoporosis. We studied a total of 136 postmenopausal women with a mean age of 56.36 +/- 10.29 years. Among them, a total of 75 had osteoporosis, 37 had osteopenia, and 24 had normal BMD. Venous blood samples were obtained for evaluation of bone metabolism and genotyping. The VDR Apa I genotype was determined by polymerase chain reaction-restriction fragment length polymorphism. BMDs at the lumbar spine and hip were measured by dual-energy X-ray absorptiometry. Postmenopausal women with aa genotype had significantly lower BMD values (grams per centimeter square) at lumbar spines compared to persons with AA genotype. Also, postmenopausal women with AA genotype had significantly higher serum Ca level than the subjects with aa genotype. In conclusion, our result may indicate that VDR Apa I gene polymorphism may be responsible for a important part of the heritable component of lumbar spine BMD in postmenopausal women, possibly related to impaired calcium absorption from the bowel.

The effect of risedronate treatment on serum cytokines in postmenopausal osteoporosis: a 6-month randomized and controlled study.

There is much evidence suggesting that the decline in ovarian function after menopause is associated with spontaneous increases in proinflammatory cytokines. Treatment with risedronate is accompanied by significant changes in bone turnover and bone mineral density. The objective of this study was to determine the effects of risedronate treatment on the level of serum cytokines including receptor activator of nuclear factor-kappaB ligand (RANKL) and osteoprotegerin among postmenopausal women with osteoporosis. The study group consisted of 61 postmenopausal women with osteoporosis. Patients were randomly divided in two groups: In group 1 (n = 41) postmenopausal women received oral risedronate (35 mg/week), calcium (1,000 mg/day), and vitamin D (400 IU/day) for 12 months. In group 2 (control group; n = 20) patients received only oral calcium (1,000 mg/day) and vitamin D (400 IU/day). Bone mineral density (BMD) of lumbar spine (L1-L4) and proximal femur were determined using dual X-ray absorptiometry at baseline and after one year. Venous blood samples were obtained for determination of serum cytokines including interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha), RANKL, osteoprotegerin, and markers of bone formation and resorption. Levels of serum cytokines were measured before therapy and after three and 6 months. Markers of bone metabolism were studied before therapy and after 6 months. In group 1 (risedronate plus calcium/vitamin D-treated patients), serum levels of RANKL and IL-1beta significantly decreased and the level of osteoprotegerin significantly increased after three and 6 months, but no significant difference was found in TNF-alpha level. In group 2, however, the level of serum cytokines did not change after three and 6 months. In cases of bone turnover, both markers of bone resorption and formation significantly decreased after 6 months in group 1. In conclusion risedronate could improve osteoporosis by increasing osteoprotegerin and reducing RANKL and IL-1beta.

Continuous passive motion provides good pain control in patients with adhesive capsulitis.

Painful stiffening of the shoulder, 'frozen shoulder' is a common cause of shoulder pain and disability. Continuous passive motion (CPM) is an established method of preventing joint stiffness and of overcoming it. A randomized, comparative prospective clinical trial was planned to compare the early response with different rehabilitation methods [CPM vs. conventional physiotherapy treatment (CPT) protocol] for adhesive capsulitis taking into consideration the clinical efficacy. A total of 57 patients with frozen shoulder were included in this study. Patients were assigned randomly to receive daily CPM treatments or CPT protocol. Parameters were measured at baseline, and at weeks 4 and 12. All patients were evaluated with respect to pain (visual anologue scale) at rest, pain at movement, pain at night, measurement of range of motion (shoulder flexion, abduction, internal-external rotation were assessed), constant functional shoulder score and the shoulder pain and disability index. The first group (n=29) (CPM group) received CPM treatments for 1 h once a day for 20 days during a period of 4 weeks. The second group (n=28) (CPT group) had a daily physiotherapy treatment protocol including active stretching and pendulum exercises for 1 h once a day for 20 days during a period of 4 weeks. All patients in both groups were also instructed in a standardized home exercise programme consisting of passive range of motion and pendulum exercises to be performed every day. In both groups, statistically significant improvements were detected in all outcome measures compared with baseline. Pain reduction, however, evaluated with respect to pain at rest, at movement and at night was better in CPM group. In addition the CPM group showed better shoulder pain index scores than the CPT group. CPM treatment provides better response in pain reduction than the conventional physiotherapy treatment protocol in the early phase of treatment in adhesive capsulitis.

Laser therapy in the treatment of carpal tunnel syndrome: a randomized controlled trial.

OBJECTIVE: This prospective, randomized, placebo-controlled trial aimed to investigate the efficacy of laser therapy in the treatment of carpal tunnel syndrome (CTS). BACKGROUND DATA: Low-level laser therapy (LLLT) has been found to have positive effects in the treatment of CTS and various musculoskeletal conditions. METHODS: A total of 81 patients were included in this study. Diagnosis of CTS was based on both clinical examination and electromyographic (EMG) study. Patients were randomly assigned into two groups. Group 1 (n = 41) underwent laser therapy (7 joules/2 min) over the carpal tunnel area. Group 2 (n = 40) received placebo laser therapy. All patients received therapy five times per week, for a total of 10 sessions. Patients also used a wrist splint each night. Patients were assessed according to pain, hand-pinch grip strength, and functional capacity. Pain was evaluated by Visual Analog Scale (VAS; day-night). Hand grip was measured by Jamar dynometer, and pinch grip was measured by pinchmeter. Functional capacity was assessed by a self-administered questionnaire for severity of symptoms. RESULTS: The mean age of the patients (70 women, 11 Men) was 49.3 +/- 11.0 (range, 26-78). After therapy there were statistically significant improvements in VAS, pinch grip, and functional capacity measurement in both groups (p < 0.001). Hand grip was found to have been improved in the laser group. In EMG, there were statistically improvements in sensory nerve velocity, and sensory and motor distal latancies in the laser group (p < 0.001). Only sensory nerve velocity was meaningful in the placebo group. CONCLUSION: In using LLLT, (1) there was no difference relative to pain relief and functional capacity during the follow-up in CTS patients; (2) there were positive effects on hand and pinch grip strengths.
