RESUMO
PURPOSE: Complex regional pain syndrome (CRPS) is one of the common complications in stroke patients. Sympathetic dysfunction is usually considered underlying pathology. The evidence for contrast bath (CB) used in the treatment of CRPS is limited. The aim of the study is to investigate the possible effects of CB on the sympathetic activity in poststroke CRPS. MATERIALS AND METHODS: Stroke patients with CRPS (CRPS group) and without CRPS (control group) were included in the study. Age, gender, duration of stroke, aetiology, plegic side, dominant hand, spasticity level, Brunnstrom stages, and comorbidities were recorded. CB was performed for one session to the plegic side of the CRPS and control groups. Sympathetic skin responses (SSR) was recorded from the plegic and healthy hands of participants at pre-CB and post-CB. RESULTS: Each group consisted of 20 participants. No significant difference was detected in stroke duration, aetiology, and Brunnstrom stages between groups. Elbow spasticity level was significantly higher in CRPS group (p = .034). SSR amplitudes of plegic hands were significantly decreased after CB in CRPS and control groups (p = .0002, p = .013 respectively). Also, CB reduced the SSR amplitude of healty side in CRPS group (p = .003). There was no statistically significant change in SSR latency or percentage changes of SSR amplitude and latency after CB in both groups. CONCLUSION: CB leads to a significant reduction in sympathetic activity of plegic side of stroke patients. Also, CB to the plegic side has an inhibitory effect on sympathetic activity of healty side in poststroke CRPS. ClinicalTrials.gov ID: NCT04198532.

STUDY DESIGN: An experimental design. OBJECTIVES: The aim of this study was to determine the latencies of vibration-induced reflexes in individuals with and without spinal cord injury (SCI), and to compare these latencies to identify differences in reflex circuitries. SETTING: A tertiary rehabilitation center in Istanbul. METHODS: Seventeen individuals with chronic SCI (SCI group) and 23 participants without SCI (Control group) were included in this study. Latency of tonic vibration reflex (TVR) and whole-body vibration-induced muscular reflex (WBV-IMR) of the left soleus muscle was tested for estimating the reflex origins. The local tendon vibration was applied at six different vibration frequencies (50, 85, 140, 185, 235, and 265 Hz), each lasting for 15 s with 3-s rest intervals. The WBV was applied at six different vibration frequencies (35, 37, 39, 41, 43, and 45 Hz), each lasting for 15 s with 3-s rest intervals. RESULTS: Mean (SD) TVR latency was 39.7 (5.3) ms in the SCI group and 35.9 (2.7) ms in the Control group with a mean (95% CI) difference of -3.8 (-6.7 to -0.9) ms. Mean (SD) WBV-IMR latency was 45.8 (7.4) ms in the SCI group and 43.3 (3.0) ms in the Control group with a mean (95% CI) difference of -2.5 (-6.5 to 1.4) ms. There were significant differences between TVR latency and WBV-IMR latency in both the groups (mean (95% CI) difference; -6.2 (-9.3 to -3.0) ms, p = 0.0001 for the SCI group and -7.4 (-9.3 to -5.6) ms, p = 0.011 for Control group). CONCLUSIONS: The results suggest that the receptor of origin of TVR and WBV-IMR may be different.

Background/aim: ß1-selective beta-blockers (BBs) are sympatholytic agents, and discerning their effects on bone health would be of great importance. This study aimed to investigate the influence of ß1-selective BBs on bone mineral density (BMD) and fracture risk. Materials and methods: This study included postmenopausal women who used ß1-selective BBs (BB group) and control group. Sociodemographic characteristics, BMD and previous fragility fractures were recorded. Additionally, the 10-year probability of a major osteoporotic and hip fracture was calculated using the fracture risk assessment tool (FRAX). Results: A total of 60 participants were included in the study. L1-4 and L2-4 BMD values were significantly higher in BB group than control group (P = 0.015 and P = 0.025, respectively). Moreover, T-scores of lumbar and femur total were significantly higher in the BB group. Two patients in BB and 6 patients in control group had previous fragility fracture. No statistically significant intergroup difference was noted regarding FRAX. Conclusion: Based on our results, ß1-selective BB usage was associated with higher BMD at the lumbar region in postmenopausal women.

Background and purpose: After carpal tunnel surgery, some patients report complaints such as edema, pain, and numbness. Purpose - The aim of this study was to evaluate autonomic nervous system function in patients with a history of carpal tunnel surgery using sympathetic skin response (SSR). Methods: Thirty three patients (55 ±10 years old) with a history of unilateral operation for carpal tunnel syndrome were included in the study. The SSR test was performed for both hands. Both upper extremities median and ulnar nerve conduction results were recorded. Results: A reduced amplitude (p=0.006) and delayed latency (p<0.0001) were detected in the SSR test on the operated side compared to contralateral side. There was no correlation between SSR and carpal tunnel syndrome severity. Conclusion: Although complex regional pain syndrome does not develop in patients after carpal tunnel surgery, some of the complaints may be caused by effects on the autonomic nervous system.

INTRODUCTION: A 50-year-old man developed intermittent paresthesia of the outer portion of the right thumb. Paresthesia increased with thumb abduction and flexion. The remainder of the physical examination was normal. METHODS: Routine motor and sensory examinations of the median and ulnar nerves were within normal ranges. RESULTS: Ultrasonographic studies revealed that a tenosynovitis of the flexor pollicis longus of the right thumb was compressing the radial digital nerve of the thumb. CONCLUSIONS: Ultrasonographic evaluation was used in conjunction with nerve conduction studies to diagnose digital neuropathy. Ultrasound is a beneficial, complementary tool to electrodiagnostic studies, especially for uncommon focal neuropathies.

The aim of this study was to obtain the ultrasonographical reference values of ulnar nerve cross-sectional areas at the common areas of nerve entrapment as well as any differences related to age, sex, weight, height, dominant arm. Cross-sectional areas of the ulnar nerves of 72 healthy volunteers were measured bilaterally at the level of the epicondyle, 2 cm proximal to and 2 cm distal to the epicondyle, just at the entrance of cubital tunnel, at arterial split, at Guyon's canal. Age, sex, body weight, height, body mass index, and dominant extremity were recorded. The mean ulnar nerve cross-sectional area was 5.8 ± 1.1 mm(2) at 2 cm proximal to medial epicondyle, 6.2 ± 1.1 mm(2) at the medial epicondyle, 5.6 ± 0.9 mm(2) at the entrance of the cubital tunnel, 5.6 ± 1.0 mm(2) at 2 cm distal to medial epicondyle (inside the flexor carpi ulnaris), 5.0 ± 0.6 mm(2) at arterial split, and 4.9 ± 0.6 mm(2) at Guyon's canal. There was statistically no difference between the dominant and nondominant sides (p > 0.05). Females had statistically smaller nerves than males (p < 0.05). There was a significant correlation with height at all levels; also, weight was significantly correlated with cross-sectional areas except at two levels: tip of medial epicondyle and 2 cm distal. This study provides normative data of ulnar nerve ultrasonography and as well as any differences related to age, sex, height, weight, and dominant arm.

We aimed to evaluate the relation between the severity of carpal tunnel syndrome and metabolic syndrome. One hundred and fifty patients who had a clinical and electrophysiologically confirmed diagnosis of carpal tunnel syndrome (CTS), were included in this study. The patients were divided into two groups (with or without metabolic syndrome) according to the criteria of National Cholesterol Education Program. Eighty one (73.5 %) of the patients with CTS had metabolic syndrome. The patients with metabolic syndrome the severity of CTS was found 22.2 % had mild CTS, 56.8 % had moderate CTS, and 21 % had severe CTS. The patients without metabolic syndrome the severity of CTS was found 44.9 % had mild CTS, 40.6 % had moderate CTS, and 14.5 % had severe CTS. The severity of CTS between both groups was found to be statistically significant (p = 0.0009). While a correlation was found between the severity of CTS and high level of LDL with the presence of metabolic syndrome (correlation coefficient 0.209). In conclusion metabolic syndrome that appears to be a risk factor for CTS. At the same time, the presence of metabolic syndrome increases the severity of the disease.

OBJECTIVE: The detailed assessment of soft tissues over bony prominences and identification of methods of predicting pressure sores would improve the quality of care for patients with spinal cord injury (SCI). Comparing skin thicknesses on bony prominences in patients with SCI to those in healthy individuals will represent, to our knowledge, the first study aimed at determining whether differences in skin thicknesses between these groups can be detected by ultrasound. DESIGN: In both patients and controls, skin thicknesses on the sites at risk for pressure ulcers - sacrum, greater trochanter, and ischium - were evaluated using high-frequency ultrasound. The waist was also evaluated by the same method for control as it was considered to be a pressure-free region. PARTICIPANTS: Thirty-two patients with complete thoracic SCI and 34 able-bodied individuals. RESULTS: The skin was significantly thinner over the sacrum and ischial tuberosity in individuals with SCI compared with healthy individuals. No significant differences were observed in skin thicknesses over the greater trochanter or the waist between the two groups. CONCLUSIONS: Protecting skin integrity in patients with paraplegia is challenging due to many contributing factors, such as prolonged pressure, frictional/shearing forces, and poor nutrition. Thinning of the skin can increase the risk of soft tissue damage, leading to pressure ulcers. The significant differences in skin thickness at the sacrum and ischium provide the basis for establishing the early signs of pressure damage. Measuring skin thickness by ultrasound is a reliable non-invasive method that could be a promising tool for predicting pressure ulcers.

BACKGROUND AND PURPOSE: Researchers have shown an increased interest in proprioception deficits of the paretic side in hemiplegic patients. However, far too little attention has been paid to the proprioception sense of the non-hemiparetic side. The objective of this research was to determine whether the position sense of the ankles, especially of the non-paretic side, is affected in stroke patients. METHODS: 20 inpatients with stroke and 10 healthy control subjects were evaluated using an isokinetic dynamometer. Proprioceptive error scores (in degrees) for passive reproduction of joint position tests (PRJPTs) were measured. RESULTS: Error values of PRJPT for 5° plantarflexion, 10° plantarflexion, and 15° dorsiflexion were significantly higher in patients on both the paretic and non-paretic side compared with the control group dominant side. CONCLUSION: The impaired results of PRJPT in both the paretic and non-paretic ankles of stroke patients are surprising when one expects that the non-paretic side would be preserved under the control of the healthy hemisphere.

Reported here is a 46-year-old man who was seen for pain, numbness, and weakness in his left upper limb and hand. Electromyographic studies demonstrated denervation of ulnar-innervated muscle groups except for the flexor carpi ulnaris. A localized nerve conduction block could not be depicted because of severe axonal loss. Ultrasonographic evaluation showed enlargement of the ulnar nerve at 2 sites: at the level of the epicondylar groove and the inside of the flexor carpi ulnaris muscle. Herein, we would like to emphasize the complementary role of an ultrasound in peripheral nerve pathologies, not only does it confirm the entrapment but it also displays the underlying cause(s).

Antibodies to cyclic citrullinated peptides (anti-CCP) are highly specific for the diagnosis of rheumatoid arthritis (RA) with a marginal increased prediction of the disease. In this study, we aimed to investigate the relation of the presence of anti-CCP with clinical manifestations and disease activity in a cohort of RA patients. A total of 61 RA patients were included in this study. Data of disease-related parameters such as duration of disease, medications, degree of pain (visual analog scale, VAS), disease activity score 28 (DAS-28) and health assessment questionnaire (HAQ) were recorded. Laboratory workup included erythrocyte sedimentation rate (ESR), plasma C-reactive protein (CRP), rheumatoid factor (RF), anti-CCP, complete blood count and anemia parameters. Anti-CCP positivity was associated with higher scores of DAS-28, longer duration of morning stiffness, serum RF positivity and low levels of serum ferritin, while it was not associated with disease duration, VAS, HAQ, ESR, CRP and hemoglobin.
