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.

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.

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.

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.

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.

The ulcerative colitis is a relatively common disease in the European and North American countries aince Dr. Wilks has first reported the cases in 1895, But in Korea, this disease is a rare entity and only a few case have been reported. However, rescently the diagnoetic methods for ulcerative colitis are much developed we have experienced 28 cases of ulcerative colitis which were diagnosed by endoscopy, barium enema exam and biopsy. Therefore a total of 28 patient with ulcerative colitis diagnosed and treated at the department of internal medicine of HYUH from June 1979 to June 1986 was reviewed. We obtained the results as follows; 1) The sex distribution assumed a ratio of 1 to 1.33 with 12 males and 16 females. 2) The age dietribution was relatively even but the majority of cases were between 5th and 6th decade (32.1%), 3) The most prominent clinical symptoms were rectal bleeding, abdominal pain, diarrhea, fever, wight loss and vomiting. 4) Significant laboratory findins were anemia, eleveited ESR, leukocytosis, positive stool OB, electrolyte imbalance and decreased serum albumin level. 5) As to the extent of disease determined by the barium enema examination and endoscopic exam., rectum or rectosigmoid colon is involved in majority of the cases (92.8%). 6) The endoscopic examination was performed in all 28 cases and showed significant findings such as ulceration, hyperemia, mucosal friability, bleeding etcs. 7) The barium enema examination was performed in 19 cases and showed positive findings such as ulceration, luminal narrowing, bowel shortening and rigidity in 17 cases. 8) 21 of 28 patients treated by medical therapy showed relatively improved but 4 of 28 patients was exacerbated or relapsed and one has expired.

PURPOSE: To evaluate the clinical effect of intraoperative application of polyether ester urethane (Nasopore(R)) in endonasal dacryocystorhinostomy. METHODS: Endonasal dacryocystorhinostomy was performed on 77 eyes diagnosed with nasolacrimal duct obstruction between January 2010 and February 2011. Nasopore(R) was applied to the newly-formed internal lacrimal opening in the experimental group (41 eyes), and vaseline gauze was applied in the control group (36 eyes). For the evaluation of clinical effects regarding postoperative adhesion and stenosis of the internal lacrimal opening, subjective symptom improvement, lacrimal irrigation tests, and endoscopic examinations were performed at 1 week, 2 weeks, 1 month, 3 months, and 6 months, postoperatively. RESULTS: In subjective symptom improvement and lacrimal irrigation tests, differences between the 2 groups were not statistically significant. In endoscopic findings, the Nasopore(R) group showed significantly lower severity of adhesion and stenosis of the internal lacrimal opening at 1 week, 2 weeks, and 1 month after operation (p < 0.05). CONCLUSIONS: Application of the Nasopore(R) may effectively reduce initial postoperative adhesion or stenosis of the internal lacrimal opening after endonasal dacryocystorhinostomy and has usefulness as an auxiliary method.
