Injuries and pains of musculoskeletal joint in human body is common onset in industrialized world. However, muscle fatigue plays a very significant role in contributing causes of many pains associated with musculoskeletal joints. Based on this hypothesis, degree of muscle fatigue was investigated using electromyography measurement technique during isometric and concentric/eccentric muscle contractions. Different response of the muscle fatigue between two different muscle contractions (isometric and concentric/eccentric contractions) was examined by comparison of parameters which were median frequency, median power and RMS value. Healthy 16 young persons without previous musculoskeletal diesease history were tested with Noraxon Myosystem 2000 EMG measurement system. In this study, two different exercises were performed. First exercise was concentric/eccentric exercise. Second exercise was isometric muscle contraction. In the case of the isometric exercise, median frequency was decreased, but median power and RMS were increased. However, during the concentric/eccentric exercse, median frequency was increased, but median power and RMS were decreased. Both of those revealed that the pattern of the median frequency was W type, but median power and RMS were M type as time passed. In this study, the patterns of the muscle fatigue during concentric/eccentric exercise as well as isometric exercise were identified. It will be helpful to prevent musculoskeletal injury from over-working andexercising.

We experienced one case of tuberous sclerosis occurred in brothers. Case 1 is 8-year-old male patient who presented seizure, mild mental retardation, subependimal nodule and Shagreen patch. Case 2 is 9-year-old male patient who presented adenoma sebaceum, Shagreen patch, subependymal gient cell astrocytomas. Diagnosis was confirmed by brain CT and biopsy. Brief review and related literatures were also presented.

Acute focal bacterial nephritis (AFBN), synonymous with acute lobar nephronia (ALN) or focal pyelonephritis, is an inflammatory mass without liquefaction caused by severe acute bacterial infection of kidney. Unless treated effectively, progression to a renal abscees may ensue. Clinically, AFBN presents as acute pyelonephritis, and radiologically, as focal swelling or mass. The distinction between AFBN and renal abceess or even tumor may be confusing and difficult. Ultrasonography and computerized tomography(CT) aid in establishing the correct diagnosis. However, the appearance of AFBN on sonography and CT is by no means pathognomonic. Benign or malignant renal tumors may have a similar appearance. With the clinical history, a high index of suspicion, and follow-up studies after institution of medical treatment may further aid in the differentiation. Herein we report 2 cases of AFBN, which were presented as renal masses.

Auditory agnoia is defined as a disability to recognize spoken languages and/or nonverbal environmental sounds and music despite adequate hearing while spontaneous speech, reading and writing are preserved. Usually, either bilateral or unilateral temporal lobe especially transverse gyral lesions are responsible for auditory agnosia. Subcortical lesions without cortical damage else rarely causes auditory agnosia. We pesent a 65-year-old right-handed male with generalized auditory agnosia caused by bilateral subcorcal lesions. After the two attacks of stroke, he could not understand and recognize spoken words and meet of non verbal sounds. Repetition and dictation were impossible but spontaneous speech was fluent and comprehensible even though mild paraphasic error was noted. Naming was normal. He could understand and read aloud the written words and phrases. Clinical examination of the ears was normal as were audiometry and brainstem auditory evoked potential. Brain magnetic resonance images showed a large cavitary lesion due to an old intracerebral hematoma in right subcortical temporoparietal lobe with preserved superior temporal gyrus and a slit like subcortical lesion in the left insula.

In May 1974, authors encountered a 37 year old Korean male who was suffering from very serious condition of acute abdomen. On exploratory laparotomy, a ruptured granulomatous mass in the proximal portion of the ileum showing extensive inflammatory and gangrenous changes was found and about 4 ft. long of the bowel was resected. From the honey-combed fibrous capsules in the mass, four plerocercoid larvae, spargana, measuring about 3 to 7 cm in lengths were extirpated. The patient had a past history of having eaten the raw flesh of a snake as a tonic about 7 months prior to admission. Four cases of intra-abdominal sparganosis reported previously in Korea and the present case were discussed briefly. Snakes and frogs in Korea are very important second intermediate hosts for the 1arva, Sparganum stage. It is most preferable that the habitual ingestion of the raw fleshes of them should be avoided in this country.

Dermatofibrosarcoma protuberans (DFSP) is a rare, distinctive cutaneous tumor, which consists of spindle shaped ceils arranged in densely packed interlacing bundles with the storiform or cartwheel pattern. Histologically, it resembles deep growing dermatofibroma, nodular fasciitis, neurofibroma and neural sheath tumors. DFSP is one of t.he connective tissue tumors which is difficult. to diagnose histologically as well as clinically. Recently, the immunochemical staining with a monoclonal antibody to CD34 is reported to give assistance in the clear differential diagnosis of DFSP from other fibrous or neural tumors. Herein, three cases of DFSP were stained by immunohistochemical staining with S-100 protein, vimentin, factor VIII and anti-CD34 antibody in order to assess the use of anti-CD34 in the differential diagnosis of DFSP.

A patient with extraskeletal cervical epidural Ewing's sarcoma who presented with cervical radiculopathy is reported. A 58-year-old woman presented with right posterolateral neck pain and upper extremity radiculopathy. The computed tomography myelography showed epidural and paravertebral masses on right side, with widening of the ipsilateral neural foramina at the C2-C3 level. On magnetic resonance images, the mass was isointense to soft tissue on T1-weighted images, hyperintense on T2-weighted images, and showed diffuse enhancement on GdTA enhanced T1-weighted images. The staged, combined posterior and anterior approach were done and the tumor mass was subtotally removed. During postoperative adjuvant chemotherapy with Cytoxane, Adriamycin, Vincristine, Prednisolone regimen, the patient died of severe compression of upper cervical cord by recurrent, extended tumor mass in the spinal canal.
