1/343. Pubic pain in athletes: a case due to an abscess in the obturator muscle.Pubic pain is a common symptom in soccer players. Its cause can be difficult to determine. We report a case in a 19-year-old soccer player who had an abscess in the obturator internus muscle. We are aware of only one similar report in the literature. Painful limitation of internal rotation of the hip and evidence of infection suggested the diagnosis, which was confirmed by magnetic resonance imaging. In a soccer player, a fever and groin pain do not always indicate osteitis pubis. Limitation of internal rotation of the hip should suggest a lesion in the obturator internus muscle.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
2/343. Muscle pain as a prominent feature of facioscapulohumeral muscular dystrophy (FSHD): four illustrative case reports.Clinical studies of facioscapulohumeral muscular dystrophy (FSHD) rarely report muscle pain as a significant feature of the condition. We report four adult patients with FSHD in whom muscle pain was a presenting complaint and remains their most disabling symptom. These four patients were investigated using a pain questionnaire and diary. Inflammatory and metabolic causes of muscle pain were sought by muscle biopsy and a range of biochemical investigations. All patients reported between three and seven different pains of varying site and nature. None of the group had more than one painfree day per month and all complained of disturbed sleep. While some pains could potentially be attributed to postural problems, others were clearly myalgic in nature, though most often not specifically exercise-related. These myalgic pains could be particularly difficult to control. Results of metabolic investigations and muscle biopsy revealed no clue to the pathogenesis of these pains and there was no evidence for any exceptional inflammatory response. We believe that pain in FSHD is an under-reported but significant symptom and that further work is necessary to determine its prevalence, understand its cause and provide effective treatment.- - - - - - - - - - ranking = 0.83333333333333keywords = muscle (Clic here for more details about this article) |
3/343. Low power laser therapy and analgesic action.OBJECTIVE: The semiconductor or laser diode (GaAs, 904 nm) is the most appropriate choice in pain reduction therapy. SUMMARY BACKGROUND DATA: Low-power density laser acts on the prostaglandin (PG) synthesis, increasing the change of PGG2 and PGH2 into PG12 (also called prostacyclin, or epoprostenol). The last is the main product of the arachidonic acid into the endothelial cells and into the smooth muscular cells of vessel walls, that have a vasodilating and anti-inflammatory action. methods: Treatment was performed on 372 patients (206 women and 166 men) during the period between May 1987 and January 1997. The patients, whose ages ranged from 25 to 70 years, with a mean age of 45 years, suffered from rheumatic, degenerative, and traumatic pathologies as well as cutaneous ulcers. The majority of patients had been seen by orthopedists and rheumatologists and had undergone x-ray examination. All patients had received drug-based treatment and/or physiotherapy with poor results; 5 patients had also been irradiated with He:Ne and CO2 lasers. Two-thirds were experiencing acute symptomatic pain, while the others suffered long-term pathology with recurrent crises. We used a pulsed diode laser, GaAs 904 nm wavelength once per day for 5 consecutive days, followed by a 2-day interval. The average number of applications was 12. We irradiated the trigger points, access points to the joint, and striated muscles adjacent to relevant nerve roots. RESULTS: We achieved very good results, especially in cases of symptomatic osteoarthritis of the cervical vertebrae, sport-related injuries, epicondylitis, and cutaneous ulcers, and with cases of osteoarthritis of the coxa. CONCLUSIONS: Treatment with 904-nm diode laser has substantially reduced the symptoms as well as improved the quality of life of these patient, ultimately postponing the need for surgery.- - - - - - - - - - ranking = 0.16666666666667keywords = muscle (Clic here for more details about this article) |

Neurologic responses: cranial nerves intact; deep tendon reflexes, 1 symmetrically; plantar reflexes, flexor bilaterally. skin: macular rash in sun-exposed areas. LABORATORY FINDINGS: Hemoglobin, 13.2 gm/dL; mean corpuscular volume, 80 micron 3; white blood cell count, 7,200/mm3 (normal differential); platelet count, 137,000/mm3. serum: electrolytes, normal; blood urea nitrogen, 18 mg/dL; creatinine, 0.8 mg/dL; glucose, 308 mg/dL; total protein, albumin, liver enzymes, and creatine kinase, normal. urine: 1 glucose. Venereal disease test: nonreactive; hiv test: negative. DIFFERENTIAL diagnosis: dermatomyositis; heavy-metal poisoning; diabetic amyotrophy. HOSPITAL COURSE: The patient was given 50 mg/day of oral amitriptyline to alleviate the painful paresthesias and was switched to 20 U/day of subcutaneously injected neutral protamine Hagedorn (NPH) insulin to normalize the blood glucose level. Histologic studies of skin and muscle showed sun damage and neuropathic changes, respectively. There was no evidence of vasculitis. Screening for heavy-metal toxins produced negative results.- - - - - - - - - - ranking = 0.16666666666667keywords = muscle (Clic here for more details about this article) |
5/343. Current therapy in the management of heterotopic ossification of the elbow: a review with case studies.Heterotopic ossification, or the appearance of ectopic bone in para-articular soft tissues after surgery, immobilization, or trauma, complicates the surgical and physiatric management of injured joints. The chief symptoms of heterotopic ossification are joint and muscle pain and a compromised range of motion. Current therapies for prevention or treatment of heterotopic ossification include surgery, physical therapy, radiation therapy, and medical management. Unlike heterotopic ossification of the hip, heterotopic ossification of the elbow has not been extensively investigated, leaving its optimal management ill-defined. To remedy this deficiency, we review risk factors, clinical anatomy, physical findings, proposed mechanisms, and current practice for treatment and prevention of heterotopic ossification. We then consider and draw conclusions from four cases of elbow injury treated at our institutions (three complicated by heterotopic ossification) in which treatment included surgery, radiation therapy, physical therapy, and medical therapy. We summarize our institutional practices and conclude with a call for a randomized clinical trial to better define optimal management of heterotopic ossification of the elbow.- - - - - - - - - - ranking = 0.16666666666667keywords = muscle (Clic here for more details about this article) |
6/343. Tumor-induced osteomalacia and symptomatic looser zones secondary to mesenchymal chondrosarcoma.Tumor-induced osteomalacia is a rare clinical entity that is associated with soft-tissue or skeletal tumors. We present a case report of a patient with a chest wall mesenchymal chondrosarcoma who presented with bone pain. The patient had skeletal changes in the femoral neck and fibula consistent with osteomalacia and laboratory values suggesting phosphate diabetes. The patient was treated with tumor resection and phosphate supplementation with reversal of the signs and symptoms of osteomalacia. Tumor-induced osteomalacia is vitamin-D-resistant and often reversed by complete removal of the tumor. Most commonly, the causative tumors are of vascular, mesenchymal, or fibrous origin. The osteomalacia is associated with bone pain, muscle weakness, and radiographic changes. Tumor-induced humoral factors have been implicated in causing the osteomalacia, but the definite etiology has yet to be determined. Current treatment includes complete tumor resection and electrolyte supplementation.- - - - - - - - - - ranking = 0.16666666666667keywords = muscle (Clic here for more details about this article) |
7/343. Distal neuralgic amyotrophy.Neuralgic amyotrophy consists of severe pain around the shoulder and arm followed by weakness in one or several muscles of the same area. We describe four patients with distal neuralgic amyotrophy in whom acute, severe, and transient pain around the shoulder or arm was followed by weakness of the forearm and hand muscles only. Minor sensory symptoms were present in only one patient. The presence of structural lesions causing the extent of the forearm and hand motor deficit was excluded by ancillary examinations. Electrophysiological studies showed a motor axonopathy and minimal sensory axonopathy. A follow-up of 2 years or longer showed either spontaneous improvement or residual motor deficit. Unfamiliarity with a clinically distal localization of neuralgic amyotrophy may result in misdiagnosis of lower cervical (poly)radiculopathy in view of the distal localization of the motor deficit and the high prevalence of coincidental abnormalities of the lower cervical spine on plain radiography, computed tomography, or magnetic resonance imaging.- - - - - - - - - - ranking = 0.33333333333333keywords = muscle (Clic here for more details about this article) |
8/343. Mitochondrial 3243 A-->G mutation (MELAS mutation) associated with painful muscle stiffness.The mitochondrial mutation A-->G at nucleotide position 3243 is associated with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) and other mitochondrial encephalomyopathies. We found this mutation in a 61-year-old patient who developed at the age of 54 a myopathy with painful muscle stiffness as the predominant symptom. Additionally hypacusis, a mild hemisensory syndrome and impaired glucose tolerance were present. Muscle histopathology showed few ragged red fibers. The mutation was detected heteroplasmatically in dna from muscle and blood. So far painful muscle stiffness has not been a known phenotype of the 3243 mutation.- - - - - - - - - - ranking = 1.1666666666667keywords = muscle (Clic here for more details about this article) |
9/343. The use of patient-controlled boluses of local anaesthetic via a psoas sheath catheter in the management of malignant pain.patients who develop malignant infiltration of the psoas muscle and the lumbar plexus often experience a severe complex pain syndrome characterised by deep somatic pain, neuropathic pain and psoas spasm. Conventional analgesic regimes may not relieve these symptoms adequately. We describe the use of patient-controlled boluses of local anaesthetic via a psoas sheath catheter in this scenario. The recent availability of portable infusion pumps with the capability to deliver large volume boluses with long lockout times made this intervention possible and allowed the patient to be discharged home with effective relief of pain.- - - - - - - - - - ranking = 0.16666666666667keywords = muscle (Clic here for more details about this article) |
10/343. syringomyelia and complex regional pain syndrome as complications of multiple sclerosis.OBJECTIVE: To describe a patient from Southeast asia with the optic-spinal phenotype of multiple sclerosis who developed syringomyelia and resultant complex regional pain syndrome (formerly named reflex sympathetic dystrophy). DESIGN: Case report. SETTING: Department of neurology at a tertiary care hospital in the Republic of singapore. PATIENT: A 53-year-old Chinese woman with a history of optic neuritis developed an episode of left hemiparesis leading to a diagnosis of multiple sclerosis. Serial neuroimaging studies revealed an active demyelinating plaque in the cervical area that later progressed into a syrinx. Over a period of 1 year she also developed signs of sympathetic dysfunction including horner syndrome of the left eye and complex regional pain syndrome in the left hand. CONCLUSIONS: A case of the optic-spinal phenotype of multiple sclerosis that is commonly observed in Southeast asia is described. This characteristically tissue-destructive form of multiple sclerosis resulted in syringomyelia complicated by a complex regional pain syndrome. Possible pathogenic mechanisms for these associations are discussed.- - - - - - - - - - ranking = 0.04799100153797keywords = paresis (Clic here for more details about this article) |
