An investigation of biomechanics, muscle performance, and disability level of craniocervical region of individuals with temporomandibular disorder.

OBJECTIVE: To investigate biomechanics, muscle performance, and disability of the craniocervical region in temporomandibular disorder (TMD) patients and compare them with controls. METHODS: Craniocervical posture was evaluated using lateral photography and radiography. Range of motion, muscle performance, disability, and TMD severity were assessed using an inclinometer, Functional Strength Testing of Cervical Spine, Neck Disability Index, and Fonseca Anamnestic Index, respectively. RESULTS: Compared to the control group, the TMD group demonstrated higher cervical flexion angle (p=0.005) and neck disability (p<0.001) as well as lower cervical extension (p=0.040), right cervical rotation (p=0.005), left cervical rotation (p<0.001), and tragus-C7-horizontal (p=0.048) angles, and reduced muscle performances (p≤0.001). Most patients had higher than normal craniocervical angle (p<0.001). Muscle performance in each cervical motion (p<0.005) and disability (p<0.001) were associated with TMD severity in the TMD group. CONCLUSION: Biomechanics, muscle performance, and disability of craniocervical region were altered in the TMD group.

EURO-MUSCULUS/USPRM Global Report on Musculoskeletal Ultrasound Publications.

The developments in technology have improved access to the use of musculoskeletal ultrasound (MSUS) in different clinical settings. Accordingly, MSUS has been applied to a wide range of musculoskeletal problems including inflammatory and degenerative diseases, sport injuries, and regional pain syndromes both for clinical practice and research. In this report, the authors aimed to globally examine the publications on MSUS among different specialties, countries, and topics. Sixteen reviewers under the umbrella of the European Musculoskeletal Ultrasonography Society Group and the Ultrasound Study Group of International Society of Physical and Rehabilitation Medicine have evaluated approximately 15,000 publications on MSUS. The authors believe that the results of this comparative analysis may provide a holistic snapshot with regard to the utility of MSUS, not only for clinicians/academicians but also for the industry. Accordingly, while aiming to further increase their awareness, this article would possibly guide future investments as well.

Botulinum toxin injections to cranial sutures for chronic migraine Rewinding the technique using ultrasound imaging.

The treatment of chronic migraine headache is quite challenging and new alternatives are still being explored for its management. Onabotulinum toxin A (BoNT-A) applied into extracranial muscles has been shown to inhibit the release of acetylcholine and local nociceptive peptides at the sensory nerve endings. As the highest concentration of extracranial pain fibers are located at/nearby the sutures, extracranial applications of BoTN-A are suggested to be performed to sutures rather than into the head and neck muscles in the treatment of chronic migraine. Moreover, in an animal study, BoTN-A is found to be more effective for decreasing the chemosensitivity of meningeal nociceptors when the total dose is injected along the sutures in comparison to being divided into sutures and cranial muscles. Of note, since BoNT-A injections performed with the blind/nontargeted technique have lower effectivity and several complications (muscle weakness, ptosis, facial paresis, etc.), the use of ultrasound guidance for targeting the cranial sutures is definitely expected to provide technical ease, better pain relief and toxin tolerance in chronic migraine.

Selective peripheral neurolysis using high frequency ultrasound imaging: a novel approach in the treatment of spasticity.

BACKGROUND: Chemoneurolysis is used to treat focal spasticity in patients with upper motor neuron syndrome. CASE REPORT: Neurolytic substances (phenol/alcohol) injected nearby/in the main trunk of peripheral nerves can cause not only motor but also cutaneous nerves destruction. The latter is thought to be responsible for considerable side effects such as dysesthesia and paresthesia. During injections, targeting the primary motor branches originating from the main trunk while sparing cutaneous nerves will result in decrease/elimination of these side effects and better clinical improvement. CLINICAL REHABILITATION IMPACT: We suggest that high frequency ultrasound enabling the physician to scan peripheral nerves and their primary branches can be useful to perform this selective peripheral neurolysis in the treatment of spasticity.

Ultrasound Imaging for Muscle Variations: Digastric Flexor Carpi Ulnaris, Gastrocnemius Tertius, and Supernumerary Fibularis Longus in an Asymptomatic Family.

Anatomical variations of the muscles are seen with different frequencies. Although most of them are asymptomatic; in certain cases, their existence requires attention with regard to entrapment syndromes, mass lesions, botulinum toxin injections, and tendon transfers. Herein, as ultrasound imaging is a convenient method for muscle imaging, it can easily be used in daily practice for prompt understanding of such muscular variations. In this report, we demonstrated and discussed a similar scenario in an asymptomatic individual (and his close family members) using ultrasound imaging for scanning the digastric flexor carpi ulnaris, gastrocnemius tertius, and supernumerary fibularis longus muscles.

Comparison of biochemical parameters of blood and urine in spinal cord injury patients and association with urinary stone formation.

OBJECTIVE: The aim of this study was to compare the biochemical parameters of the urine and blood in spinal cord injury (SCI) patients and healthy subjects. METHODS: Thirty male patients with SCI were enrolled. Biochemical features of the urine and blood of the SCI patients were compared to healthy subjects. Extracted stones were analyzed by X-ray diffraction. RESULTS: A total of 30 patients with SCI (mean age of 28.77 ± 7.3 years) and 10 healthy subjects (mean age of 27.6 + 6.2 years) were included. Among the patients with SCI; 12 of them (40%) had urinary stones and 18 of them (60%) did not. Urinary stone was localized in the kidneys and bladder in 25% and 75% of the subjects, respectively. The mean duration of cord injury at diagnosis of urinary stone was 9.2 ± 6 months. Urine cultures obtained on admission were negative for the control group, while the microorganism isolation rate was 73.3% in the SCI group. The urinary excretion of citrate and Mg were lower in the patient group compared with control group (p= 0.008, p= 0.001, respectively). As for the diffraction analysis of eight stones; five (62.5%) of the stones were calcium oxalate, two (25%) of them were calcium phosphate, and one (12.5%) was magnesium ammonium phosphate. CONCLUSION: Both infection and metabolic changes play an important role in stones formation in SCI patients. The urinary excretion of citrate and Mg was decreased and urinary PH was increased in SCI patients.

Effect of Platelet-Rich Fibrin on Peripheral Nerve Regeneration.

PURPOSE: This study aimed to evaluate the effect of platelet-rich fibrin (PRF) on peripheral nerve regeneration on the sciatic nerve of rats by using functional, histopathologic, and electrophysiologic analyses. MATERIALS AND METHODS: Thirty female Wistar rats were divided randomly into 3 experimental groups. In group 1 (G1), which was the control group, the sciatic nerve was transected and sutured (n = 10). In group 2 (G2), the sciatic nerve was transected, sutured, and then covered with PRF as a membrane (n = 10). In group 3 (G3), the sciatic nerve was transected, sutured by leaving a 5-mm gap, and then covered by PRF as a nerve guide (n = 10). Functional, histopathologic, and electrophysiologic analyses were performed. RESULTS: The total histopathologic semiquantitative score was significantly higher in G1 compared to G2 and G3 (P < 0.05). Myelin thickness and capillaries were significantly lower in G3 compared to G1 (P < 0.05). There was no statistically significant difference between the groups with regard to the functional and electrophysiologic results. CONCLUSION: The study results suggest that PRF decreases functional recovery in sciatic nerve injury. Further studies are required to determine the efficacy of PRF on peripheral nerve regeneration.

Evaluation of intraabdominal hypertension and genitofemoral nerve motor conduction.

BACKGROUND/AIM: The aim of this study was to electrophysiologically evaluate the effect of increased intraabdominal pressure (IAP) on genitofemoral nerve (GFN) motor conduction. MATERIALS AND METHODS: Seven Wistar albino rats were included. After anesthetization, latency and duration of GFN conduction was recorded with a needle-probe at rest. IAP was increased to 15 mmHg by insufflating atmospheric air with a percutaneous intraperitoneal needle. At 30 min of IAP, GFN motor conduction was recorded. Abdominal pressure was then increased to 20 mmHg. At 60 min, GFN motor conduction was recorded again. The consecutive recordings of latency and duration of GFN conduction (rest, 30 min, 60 min) were evaluated statistically. RESULTS: There was a significant difference between latencies at rest (1.90 ± 0.22 ms), at 30 min (2.3 ± 0.36 ms), and at 60 min (2.74 ± 0.57 ms) (Friedman test, P = 0.001). The latency was significantly increased at 60 min compared to rest (post hoc Tukey test, P = 0.003). No similar difference was detected between the recordings at 30 and 60 min. The duration of GFN motor conduction showed no difference between consecutive recordings (P = 0.067). CONCLUSION: Both increased and prolonged IAP causes prolonged latency of GFN conduction, probably due to a compression effect on GFN. Neuropraxial consequences of increased IAP are thought to be related to the compression effect of peripheral nerves.

Conservative treatment of femoral neuropathy following retroperitoneal hemorrhage: a case report and review of literature.

Anticoagulant drugs are used to reduce the incidence of thromboembolic events in patients at risk. However, minor and major bleeding complications may occur during anticoagulation therapy. Femoral neuropathy secondary to retroperitoneal hematoma is a well known complication of anticoagulant drugs. However, treatment of these patients is still controversial, both conservative and surgical treatments have been advocated. Herein, we report a male patient receiving warfarin for 7 years who developed femoral neuropathy due to retroperitoneal hematoma and was successfully treated with conservative methods. We suggest that conservative treatment and appropriate rehabilitation program should be given to the patients who do not demonstrate any signs of a continued bleeding and any progressive neurological deficits.

Correlations among enthesitis, clinical, radiographic and quality of life parameters in patients with ankylosing spondylitis.

OBJECTIVES: To investigate the relationship between enthesitis and disease activity, functional status, fatigue, joint mobility, radiological damage, laboratory parameter and quality of life in patients with ankylosing spondylitis (AS). METHODS: A total of 421 patients with AS (323 male and 98 female) who were included in the Turkish League Against Rheumatism Registry were enrolled in the study. The Bath AS Disease Activity Index (BASDAI), fatigue, the Bath AS Functional Index (BASFI), the Bath AS Metrology Index (BASMI), the Maastricht AS Enthesitis Score (MASES), AS quality of life (ASQoL), the Bath AS Radiology Index (BASRI) and erythrocyte sedimentation rate (ESR) were evaluated. RESULTS: Enthesitis was detected in 27.3% of patients. There were positive correlations between MASES and BASDAI, BASFI and fatigue (p < 0.05). MASES was not correlated with BASRI, BASMI, ASQoL and ESR. The mean MASES score was 1.1 ± 2.4. The most frequent regions of enthesopathies were right iliac crest, spinous process of L5 and proximal to the insertion of left achilles tendon, respectively. CONCLUSIONS: Enthesitis was found to be associated with higher disease activity, higher fatigue, worse functional status and lower disease duration. As enthesitis was correlated with BASDAI, we conclude that enthesitis can reflect the disease activity in patients with AS.

Electrophysiologic evaluation of cremasteric reflex in experimental orchitis.

AIM: Absent cremasteric reflex (CR) is a well known but not reliable sign of testicular torsion. We hypothesized that CR can also be altered in other causes of acute scrotum in children. An experimental study was performed to evaluate the clinical and electrophysiological features of CR in orchitis. METHOD: Eighteen Wistar albino rats were allocated into three groups: control (CG), sham (SG) and orchitis (OG). In CG, after anesthetization with ketamine hydrochloride, the medial site of the anterior superior iliac spine was stimulated to obtain CR electrophysiologically, and latency and duration were recorded with a needle electrode placed in the cremasteric muscle. Electrophysiologic evaluations were performed 24 h after injection of 0.1 ml of 10(6) cfu/ml Escherichia coli (0:6 strain) in 1 ml of physiologic saline into the right testicle in OG, and 1 ml of saline only in SG. All testicles were sampled to check for orchitis after the electrophysiologic evaluations. RESULTS: CR was obtained in all rats in CG and in 83.3% and 66.6% in SG and OG respectively (p < 0.05). The latency of CR was significantly higher in OG (15.1 ± 0.9 ms) and SG (15.5 ± 1.2 ms) than CG (10.5 ± 0.7 ms) (p < 0.017). The duration of CR was 15.1 ± 3.2 ms in CG, 16.2 ± 4.9 ms in SG and 18.5 ± 3 ms in OG (p > 0.05). Histopathologic confirmation of orchitis was obtained in all testicle samples in OG, and number of neutrophils and total orchitis score was significantly higher in OG than the other groups (p < 0.05). CONCLUSION: Electrophysiologic parameters of CR may be altered in orchitis. Prolonged latency of CR in orchitis may be due to inflammation of the genitofemoral nerve or cremasteric muscle.

Description of the registry of patients with ankylosing spondylitis in Turkey: TRASD-IP.

A web-based application patient follow-up program was developed to create a registry of patients with ankylosing spondylitis (AS) by the Turkiye Romatizma Arastirma Savas Dernegi (TRASD) AS Study Group. This study describes the methodological background and patient characteristics. The patient follow-up program is a web-based questionnaire, which contains sections on socio-demographic data, anamnesis, personal and family history, systemic and musculoskeletal examination, laboratory and imaging data and treatment. Between October 1, 2007 and February 28, 2009, 1,381 patients from 41 centers were included in the registry (1,038 males [75.2%]; mean age 39.5 ± 10.7 years). Mean disease duration was 12.1 ± 8.5 years, and mean time from initial symptom to diagnosis was 5 ± 6.8 years (median 2 years). HLA-B27 positivity was detected in 73.7% of 262 patients tested. Manifestations of extraarticular involvement were anterior uveitis (13.2%), psoriasis and other skin and mucous membrane lesions (6%) and inflammatory bowel disease (3.8%). The prevalence of peripheral arthritis was 11.2%. In 51.7% of patients, the Bath AS Disease Activity Index was ≥4. But since our patients consisted of the ones with more severe disease who referred to the tertiary centers and needed a regular follow-up, they may not represent the general AS population. Disease-modifying anti-rheumatic drugs were being used by 41.9% of patients, with 16.4% using anti-TNF agents. TRASD-IP (Izlem Programi: Follow-up program) is the first AS registry in Turkey. Such databases are very useful and provide a basis for data collection from large numbers of subjects. TRASD-IP gives information on the clinical and demographic profiles of patients, and the efficacy and safety of anti-TNF drugs, examines the impact on quality of life, and provides real-life data that may be used in cost-effectiveness analyses.

Effects of ovariectomy and ascorbic acid supplement on oxidative stress parameters and bone mineral density in rats.

OBJECTIVES: 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. MATERIALS AND METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.
