Inclusion body myositis (IBM) is a late-onset myopathy that manifests as distinct muscle weakness in the quadriceps, finger flexors, and ankle dorsiflexors. T-cell large granular lymphocyte (T-LGL) leukemia is a late-onset clonal disorder of CD8+ cytotoxic T-cells that is often accompanied by autoimmune diseases. To date, the association between IBM and T-LGL leukemia has been infrequently reported. Here, we report a case of a patient with T-LGL leukemia who developed IBM, along with in-depth laboratory, electrophysiological, and pathologic findings.

The inflammatory myopathies are divided into three major and distinct subsets as polymyositis(PM), dermatomyositis(DM), and inclusion body myositis(IBM). This distinction is based on unique clinical, demographic, laboratory, histologic, therapeutic, prognostic, and immunopathologic criteria. Although the causes of PM, DM, and IBM are unknown, autoimmune mechanisms are implicated, as supported by their association with other putative or definite autoimmune diseases or viruses, the evidence for a T cell-mediated myocytotoxicity or complement-mediated microangiopathy, the presence of various autoantibodies and their response to immunotherapies. But in IBM the immune-mediated process is weaker and IBM patients do not readily respond to immunotherapies, there are convincing immunopathological signs to suggest that a definite autoimmune component, similar to that seen in PM, also plays a role in the cause of IBM.

It has been reported that antisynthetase syndrome belongs to the idiopathic myositis group which includes pulmonary interstitial disease, arthritis, Raynaud's phenomenon, and mechanic's hand, associated with the anti-Jo1 antibody. A 60- year-old man presented with one month history of lower limbs weakness, rapidly progressive exertional dyspnea, and arthralgia. A markedly increased titers of anti-Jo1 antibodies were found. Chest CT showed idiopathic pulmonary fibrosis. Muscle biopsies were consistent with polymyositis. A high dose corticosteroids and cyclosporine were not effective. We report a case of antisynthetase syndrome, in which immunosuppressive agents could not rescue the deteriorating disease course.

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.

8년령 중성화 수컷 말티즈가 입을 열기 어려운 증상으로 내원하였다. 2M 항체 검사를 통해 저작근염을 진단하였다. 코르티코스테로이드로 처치 후 턱관절의 가동범위가 증가하였고, 처치 5개월 후에는 거의 정상으로 돌아왔다. 저작근염이 발생한 개에서 초기 발견 및 적극적인 면역억제 치료는 예후 향상을 위해 필요한 것으로 사료된다.

진행성 골화성 근염은 매우 드물게 보는 유전성 질환으로서 선천성 족무지 기형과 근막, 건막, 건, 인대 및 골격근육의 간질조직내 결체조직의 부종, 석회화를 거쳐 진행성으로 골화를 일으킴을 특징으로 하는 질환이다. 본 질환은 근본적으로 골격근 자체는 정상이나 근본 병리결함이 결체조직에 발생함으로 종래 사용하던 병명인 '진행성 골화성 근염' 대신 '진행성 골화성 섬유이형성증'이라 칭하는 것이 합당하다고 주장되고 있다. 저자는 최근 일가족 남매에 발생한 진행성 골화성 근염 2예를 경험하였기에 보고하는 바이다.

A dog (2-year old, female, Shih-Tzu) presented with hyperthermia and right-sided facial paralysis characterized by the inability to close the right eye and drooling from the right side of the mouth after H3N2 influenza vaccination [A/Canine/Korea/01/07(H3N2) strain; Caniflu-Max, Bionote, Hwaseong, Gyeonggi-do, ROK]. To determine the cause of the fever and neurological symptoms, physical examination, ophthalmic examination, thoracic and abdominal radiography, abdominal ultrasonography, complete blood counts, serum chemistry values, and electrolyte levels were determined. In addition, Cerebrospinal fluid analysis, antinuclear antibody test, fever of unknown origin polymerase chain reaction (PCR) panel, tick-borne pathogen PCR panel were performed. As a result, hyperthermia, leukocytosis, and elevated C-reactive protein were confirmed. In addition, neurological examination revealed decreased right eyelid reflexes, corneal reflexes, threat response, and facial sensation, it was possible to suspect problems with the trigeminal and facial nerves of the cranial nerve. Magnetic resonance imaging revealed a lesion suggestive of myositis in the right muscular lesion at atlanto-occipital junction level on site of vaccine injection. Therefore, right-sided facial paralysis was tentatively determined to be a secondary cause of nerve damage caused by myositis. The patient was treated with immunosuppressants such as prednisolone and mycophenolate mofetil. After 3 months of immunosuppressant therapy, the patient's symptoms improved.

Acute viral meningitis and myositis are rare complications of varicella-zoster virus (VZV) reactivation. A 71-years-old immunocompetent man, who presented with lower back pain radiating to the left lower extremities, developed vesicles on the L5 dermatomal area. The next day, he had complained of aberrant vesicles on the trunk, face and scalp, with generalized myalgia, headache and dizziness. He was confirmed with VZV meningitis and myositis, as demonstrated by the presence of VZV DNA in the blood and cerebral spinal fluid using a polymerase chain reaction (PCR) amplification. PCR has been used in patients with a VZV infection associated neurological symptoms, and provides a useful tool for the early diagnosis of VZV-associated neurological disease. The patient was treated with bed rest, with intravenous acyclovir for the VZV infection, and intravenous Patient-controlled Analgesia for pain management and the prevention of postherpetic neuralgia. When he visited the outpatient department 3 months later, the skin lesion, leg pain, headache and myalgia had all improved, without sequelae. Here, this case is reported, with a discussion of the relevant literature on its diagnosis and management.

To evaluate the diagnostic usefulness of radioisotope bone scan and clinical activity of myositis, bone scan using $^{99m}Tc-Methylene$ diphosphonate was serially done before and after treatment with prednisolone in 10 patients with well-documented dermatomyositis-polymyositis. The observed results were as follows. 1. In all 10 patients before treatment with prednisolone, the bone scans showed evidence of increased muscle uptake. Muscle uptake was markedly increased in 4 patients, moderately increased in 3 patients and minimally increased in 3 patients. 2. The site of increased muscle uptake was consistent with the site of clinically involved muscle which was weak and tender. 3. The degree of muscle uptake correlated with the severity of the muscle weakness and tenderness at the scan was done. In all 10 patients treated with high dose prednisolone, muscle uptake was decreased following therapy. Above results suggest the radioisotope bone scanning may be useful in the diagnosis and treatment of patient with dermatomyositis-polymyositis.
