We had experienced a case of traumatic myositis ossificans arising in right masseter muscle, inferior to zygomatic arch occurred on 25 year old male. He had some trauma on the site one year ago and visited with complaint of mouth opening limitation and swelling. Palpable mass with facial disfigurement was noted. and several ovoid radiopaque masses were revealed on C.T. examination. On histopathologic examination, multiple bone trabeculae with osteoblasts in its periphery was noted in connective tissues and invaded to neighbouring muscles, but any chondroid components were not revealed.

Purpose: Pyomyositis is a rare disease in temperature climate region. The diagnosis of pyomyositis is often delayed, and pyomyositis is often misdiagnosed in the emergency department. Methods: The medical records of 11 patients who were diagnosed as having traumatic pyomyositis in the emergency department at Samsung Medical Center in Seoul, Korea, between 2000 and 2006 were reviewed. Their clinical features, such as history, symptoms, clinical findings, duration from onset of symptoms to diagnosis, medical history, laboratory data, results of imaging studies and clinical course were collected. Results: The psoas muscles were most commonly involved. Computer tomography and magnetic resonance imaging aided in accurate diagnosis of the infection and of the extent of involvement. Incision, drainage, and antibiotics therapy eradicated the infectioin in all patients Conclusion: Pyomyositis should be a part of the differential diagnosis for patients with traumatic muscle pain. Radiologic evaluation, such as computer tomography and magnetic resonance imaging, must be considered in the diagnosis of traumatic pyomyositis.

Dermatomyositis is an inflammatory cutaneo-muscular disease of unknown etiology, characterized by symmetrical proximal muscle weakness and typical dermatologic manifestation. Henoch-Schonlein purpura is most common in children. In Korea, dermatomyositis or Henoch-Schonlein purpura associated with herbal medicine has not been reported. The subject patient is a seven year-old girl diagnosed with dermatomyositis in August 1999 and Henoch-Schonlein purpura in January, July 2001. There were symptoms of dermatomyositis such as headache, arthralgia, eruption, itching and abdominal pain. I think the herb-prescription composed or Radix astragali (Huangqi), Herba agrimoniae (Xianhecao), Fructus jujubae (Dazao) had an ameliorating effect on Henoch-Schonlein purpura by decreasing these symptoms.

Objective : This is a clinical report about the 77-years-old man patient with polymyositis treated by oriental medicine. Methods : The patient was treated by acupuncture and herb medication. The improvement of the patient was judged by MRC scale and CPK, LDH. Results & Conclusions : 1. Patient's symptoms(paraplegia) rapidly improved. 2. The level of CPK, LDH and Potassium are recovered to the normal range. 3. Associated with respiratory symptoms are getting better.

Esophageal transit of radionuclide was quantitatively analyzed in 29 patients with dermatomyositis-polymyositis. Fourteen patients (48.3%) showed retention of tracer in oropharynx. The mean value of percent retention of oropharynx was $15.5{\pm}16.6%$. Esophageal dysfunction was found in 19 patients (65.5%). Among them 4 showed mild, 12 showed moderate and 3 showed severe esophageal dysfunction. Dysphagia was found in 11 patients (37.9%), which was closely related to percent retention of oropharynx.Quantitative analysis of esophageal transit of radionuclide seemed to be a useful technique for evaluation of dysphagia in patients with dermatomyositis-polymyositis.

Sporadic inclusion body myositis (s-IBM) is an aquired slowly progressive inflammatory myopathy with unknown etiology. Although light microscopic abnormalities and characteristic histopathology on muscle biopsy distinguishes from other inflammatory myopathies, vacuolated muscle fibers, intracellular amyloid deposits or tubulofilaments in electromicroscopic findings are not definite in some patients. This review shows the prominently involved muscles in s-IBM and specific or nonspecific electrophysiologic manifestations from reported data for helping the diagnosis of definite-or probable-IBM patients. In lower limbs, the quadriceps is predominantly involved, as is iliopsoas, and tibialis anterior is common. In the upper limbs, the greatest weakness is in forearm finger flexors. Finger extensors, biceps and triceps also are moderately to prominently involved. The majority of patients demonstrate polyphasic MUAPs that are short in duration. An additional striking feature is the concomitant documentation of long-duration, large-amplitude, polyphasic MUAPs. In spite of the frequent mixed myopathic-neurogenic electromyographic findings of IBM, just like that of chronic myositis, asymmetric, slowly progressive weakness of flexor digitorum profundus or quadriceps femoris muscles after age of 50 is very necessary condition for the diagnosis of IBM.

Myositis ossificans progressiva, otherwise called fibrodysplasia ossificans progressiva is a rare hereditary disease of unknown etiology, which is characterized by progressive ectopic ossification in connective tissues of the muscles, tendons, fascia and aponeurosis. We report a case of myositis ossificans progressiva confined to hands and feet, which has an unusual clinical feature with slow progression.

Influenza is a common disease that causes epidemics yearly due to the influenza virus. If patients with influenza present with rare symptoms, the diagnosis may be delayed and the condition is difficult to treat. A 5-year-old boy presented to the emergency room with fever and cramps. Brain computed tomography showed low attenuation in the thalamus and brain stem, which was suggestive of encephalopathy caused by influenza virus. Another 5-year-old girl visited the emergency room with mild fever and painful calf edema. She was diagnosed with myositis caused by influenza and treated accordingly.

Radiation recall is an uncommon phenomenon in which administration of a chemotherapy or another systemic agent induces an acute inflammatory reaction in previously irradiated tissues, often weeks to years after completion of radiotherapy. Gemcitabine can induce an inflammatory reaction within an area of prior radiation. Radiation recall is known to medical oncologists, however only few cases have been reported in Korean journals, therefore physiatrist who diagnose and treat the treatment-related physical impairments of cancer patients must know about it. We emphasize the importance of knowledge of this phenomenon when considering the differential diagnosis of painful limb edema in a patient who has received cancer treatment.
