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.

Seborrheic keratosis is a benign epidermal lesion, that commony develops in the aged. It exhibits a remarkable spectrum of histologic variations. We evaluated one hundred and one cases of seborrheic keratoses according to the histologie typing by Lever and Schaurnburg-Lever. The most common histologic type was the acanthotic type(50.5%), and the next. most common one was hyperkeratotic type(33.7%). The rest of the caces were relatively uncommon, irritated type(6.9%), mixed type(4.9%), clonal type(3.9%), adenoidal type(2.0%), and melanoacanthoma(1.0%). In 2 cases, mixed type was found in a lesion.

We evaluated one month follow-up results of the 12 adult patients who showed ventriculomegaly in the aspects of symptoms. Evans ratio, periventricular low density, grades of radio-isotope cisternography, and grades of continuous intracranial pressure monitoring that were classified on the pressure wave and basal pressure level. The grades of continuous ICP monitoring were compared to the grades of radio-isotope cisternography. History, symptoms, CT findings, and radio-isotope cisternography are often helpful to decide shunt operation but sometimes continuous intracranial pressure monitoring gives invaluable information.

Phamacokinetic study of the antibiotic concentrations in the cerebrospinal fluid was done with high pressure liquid chromatography of CSF samples from twelve patients who had various amount of continuous extra-ventricular drainage during antibiotic administration. Five patients with large amount(over 150cc/day) of drainage had decreased CSF antibiotic concentrations dramatically below the effective concentration within 4 hours after intraventricular antibiotic administration, but six patients with small(less than 150cc/day) drainage maintained CSF antibiotic level above effective concentration even 24 hours after administration. In conclusion, repeated intraventricular administration of antibiotic is necessary to maintain the effective drug level in the patient with CSF drainage over 150cc/day.

PURPOSE: The purpose of this study was to evaluate the ultrasonographic findings of secondary appendicitis (SA) and to discuss the differential findings compared with primary appendicitis. METHODS: In this study, we analyzed the ultrasonographic findings of 94 patients under 15 years old of age treated at our institution from May 2005 to May 2014 who had bowel inflammation and an inflamed appendix with a maximal outer diameter >6 mm that improved with nonsurgical treatment (the SA group). Ninety-nine patients with pathologically proven acute appendicitis (the primary appendicitis [PA] group) from June 2013 to May 2014 and 44 patients with pathologically negative appendectomy results from May 2005 to May 2014 were also included to compare the ultrasonographic features of these conditions. A retrospective review of the ultrasonographic findings was performed by two radiologists. The clinical and laboratory findings were also reviewed. The results were statically analyzed using analysis of variance, the Pearson chi-square test, and the two-tailed Fisher exact test. RESULTS: Compared with PA, cases of SA had a smaller diameter (9.8 mm vs. 6.6 mm, P < 0.001), and were less likely to show periappendiceal fat inflammation (98% vs. 6%, P < 0.001) or an appendicolith (34% vs. 11%, P < 0.001). SA showed mural hyperemia on color Doppler ultrasonography as frequently as PA (P=0.887). CONCLUSION: The ultrasonographic features of SA included an increased diameter compared to a healthy appendix and the same level of hyperemia as in PA. However, the diameter was commonly in the equivocal range (mean diameter, 6.6 mm), and periappendiceal fat inflammation was rarely present in SA.

PURPOSE: The aim of this study was to determine the frequency, epidemiology and the clinical manifestation of human metapneumovirus (hMPV) infection in Korean children. METHODS: From February 2010 to January 2012, we collected nasopharyngeal aspiration from 1,554 children who were hospitalized for acute lower respiratory tract infections at the Department of Pediatrics, Severance Children's Hospital. hMPV was detected by performing reverse transcriptase-polymerase chain reaction (RT-PCR). The medical records of the patients with positive results were retrospectively reviewed. RESULTS: We detected hMPV in 99 of the 1,554 hospitalized children. The mean age of the hMPV infected children was 25 months, and 87% of the illnesses occurred between April and June. The most common diagnoses were pneumonia (73%) and bronchiolitis (16%). The clinical manifestations included cough, fever, respiratory distress, hoarseness, tachypnea, and wheezing. Coinfection with other respiratory viruses was found in 43 children (43%). CONCLUSION: hMPV is one of the major virus causing acute respiratory tract infection in the age between 13 months and 48 months old with peaks during April to June. Reports of hMPV in Korea has been increasing but additional studies are required to define the epidemiology and the extent of disease caused by hMPV to determine future development of this illness in Korean children.

Plexiform neurofibroma is considered a pathognomic of Von Recklinghousen's disease, which involves the deep and large nerve trunk. These are large irregular nerve fascicles which result from an increase in endoneural matrix within individual nerve facicles, without an increased number of nerve fibers. We experenced a case of Von Recklinghausen's disease in a 24 year-old male who had variable cutaneous skeletal, and CNS lesions. He presented multiple neurofibromas, cafe-au-lait spots, and axillary freckles as common cutaneous lesions of NF-I and giant pigmentation, sacral hypertrichosis, and plexiform neurofibroma as unusual cutaneous lesions. Also he had a scoliosis, bowing deformity of the humerous and wedging deformity of the body of the 5th cervical spine as a skeletal manifestation and cortical calcification in the occipital area as a CNS manifestation.

We report a case of eosinophilic pustular folliculitis in a 18-year-old woman who had numerous mild pruritic erythematous plaques with follicular papules and pustules covering almost her whole body. Histopathologically intrafollicular, perifollicular and perivascular eosinophilic infiltrates were present with mild spongiosis. The blocd eosinophil count was 9%. The patient responded well to systemic administration of corticosteroid and dapsoni.
