We report a case of acantholytic dyskeratotic epidermal nevus in a 28-year-old female. The patient showed unilateral, asymptomatic, grouped, 2 mm sized, brownish, follicular ant non-follicular, keratotic papules disposed along Blaschko´s lines on the right side of th back, flank and abdomen. She had had this condition for 4 years. The biopsy specimen obtaine, from the abdomen showed hyperkeratosis, parakeratosis, acanthosis, acantholytic suprabasal clefts, corps ronds, and grains. Although cryotherapy with liquid nitrogen was per formed on half of the lesions, the whole skin lesions healed with focal hypertrophic scars 4 weeks later. There was no recurrence after a 12 months follow-up period. To our knowledge this is the first reported case of acantholytic dyskeratotic epidermal nevus in Korean dermatologi, literature.

OBJECTIVES: The purpose of this study was to assess the clinical features, microbiologic results, and the efficacy of perineal hygienic care of pediatric vulvovaginitis. METHODS: Forty-two unselected premenarcheal patients with symptoms or signs of vulvovaginitis who were attended the outpatient pediatric and adolescent gynecology clinic at Pundang CHA General Hospital from August 1997, to September 1999 were systematically interviewed and examined using a standardized format, studied microbiologically, and followed the efficacy of perineal hygienic measures prospectively. RESULTS: The median age of the patients was 4.8 years (range 2.9 years to 10.9 years). Vaginal complaints of 42 patients were discharge(79%), genital pain or irritation(31%), odor(17%), pruritus(14%), and vaginal bleeding(7%). On physical examination, vaginal discharge and vulvar erythema were noted in 17(40%) and 22(52%) patients, respectively. Aerobic bacteria or yeast excluding vaginal normal flora were found in 24 of 42 patients(57%). Convincing evidence of specific pathogens was found in 9 of 42 patients(21%) including one case of pinworm infestation. Isolated pathogens were H. influenza(3), S. pyogenes(2), K. pneumonia(2) and N. gonorrhea(1). No patients were found to have chlamydial infection or trichomoniasis. In 14 patients, risk factors were identified such as swimming(14%), bubble bath(5%), sexual abuse(5%), genital trauma(5%) and foreign body(2%). After two weeks instructions of perineal hygienic care, 26(62%) of 42 patients revealed complete resolution of symptoms and signs of vaginitis without antibiotics. Efficacies of perineal hygienic care were 94%(17/18) in the patients with normal flora alone, 60%(9/15) in the patients with organisms suspected for nonspecific infection and 0%(0/9) in the patients with specific pathogens(p<0.05). CONCLUSION: Majority(62%) of the pediatric patients with symptoms or signs of vulvovaginitis were cured with perineal hygienic care alone. And the efficacy of hygienic measure were higher in the patients without specific pathogens(79%, 26/33). Therefore, proper physical examination, microbiologic study and appropriate instructions of perineal hygienic care were more important than empirical antibiotic treatment in initial management of pediatric vulvovaginitis.

PURPOSE: To evaluate dysphagia objectively and quantitatively, and ta clarify the effect of neck position and viscosity changes in patients with aspiration and laryngeal penetration. MATERIALS AND METHODS: We studied 35 patients with dysphagia and 21 normal controls using videofluoroscopy and scintigraphy. Videofluoroscopy was performed with barium with three different viscosity, and scintigraphy was done, with water, yogurt, and steamed egg mixed with Tc-99m tin colloid. 1f aspiration was found during videofluoroscopic examination, patients neck position was changed and study repeated. Videofluoroscopy was analyzed qualitatively. We calculated 7 quantitative parameters from scintigraphy. According to the videofluoroscopic findings, we divided patients into 3 subgroups; aspiration, laryngeal penetration, and no-aspiration group. RESULTS: The result of videofluoroscopy revealed that the most cornmon finding was the delay in triggering pharyngeal swallow. Pharyrigeal transit time (PTT) and pharyngeal swallowing efficiency(PSE) in patients with aspiration were significantly different from other groups. After neck position change, aspiration could be reduced in all of 7 patients, and laryngeal penetration reduced hy about 82%. PTT ancl PSE were also improved after position change. Aspiration and laryngeal penetration occurred more frequently in thin liquid swallowing than in thick liquid and solid swallowing. CONCLUSION: PTT and PSE were useful for the evaluation of dysphagia. Aspiration and laryngeal penetration could be reduced when appropriate position assumed, We could decrease the chance of aspiration by changing the patient diet consisIency. Scintigraphy might be useful tool to quantitate and follow up these changes.

The first myelography with air was carried out by Walter Dandy in 1919, and the myelography with positive contrast medium was done by Sicard and Forestier in 1922. Since Pantopaque was adopted as a contrast material by University of Rochester group in 1944, it has been rapidly popularized. Although higher diagnostic accuracy has been made with a development of the diagnostic aids such as electromyography, discography, epidural venography and computerized tomography, myelography has been popularized in our country with electromyography. The authars have seen and studied 107 cases of herniated lumbar disc with respect to the diagnostic accuracy of myelographic examination from January, 1976 to December, 1981 at the department of Orthopedic Surgery, Yonsei University College of Medicine. The results were as follows: l. Of the 107 cases, 59 were found in the age of 20 to 40 years and the ratio of male and female was 2:l. 2. Fifty eight cases (54.2%) had no history of back injury, but 40 cases (37.4%) had sprain of the back and 9 cases had direct trauma history. 3. In all cases, plain X-ray and myelogram were taken. Among them 55 cases showed narrowing of intervertebral space in plain film, and 100 cases showed positive myelographic findings such as lateral indentation of dural sac (41 cases), hour-glass defect (30 cases), root sleeve defect (12 cases), block defect (10 cases) and combined defects (7 cases). 4. Sixty one cases which confirmed by operation, the most frequent level of disc herniation was in L4-5 space. Clinical diagnosis was correct in 57.4%, and myelographic accuracy was coincided with operative finding in 80.3%. 5. Twelve (19.7%) of the 61 cases showed discrepancy between myelographic and operative findings, and these 12 cases consisted of 5 cases of level discrepancy, 3 cases of false positive and 4 cases of false negative.

The oropharyngeal swallow of 26 patients with dysphagia was studied quantitatively and qualitatively using videofluoroscope. Videofluoroscopic examination was done with head in neutral position, and with three different c onsistency of test meals; thin liquid, thick liquid, and solid, When aspiration or laryngeal penetration was noted in neutral position, the study was repeated with different head positions, We compared them with each other and with 25 normal subject(previously presented). 11/26(42%) patients revealed laryngeal penetration or aspiration at least with one consistency of test meal. Aspiration occurred more frequently in thin liquid than thick liquid or solid, Head position change successfully eliminated aspiration in 10/10 patients(100%). Other one patient could not change his head position. 9 numerical parameters were derived and calculated for quantitative examination, Liquid meal oral discharge time, pharyngeal delay time, and pharyngeal transit time were significantly increased in patients with aspiration than in patients without aspiration. Also significantly increased than those of normal controls. Because different test meal consistency gave different values, direct comparison of values regardless of meal consistency was fruitless. And because all the process of swallowing cannot be expressed as numerical parameters qualitative examination of videofluoroscopic result was essential. In conclusion, liquid meal oral discharge time, pharyngeal delay time, and pharyngeal transit time were useful parameters in differentiating and quantifying dysphagia. Aspiration can be reduced when appropriate position assumed. Calculated values were different a according to the consistency of the test meal. Quantitative analysis was helpful, but qualitative examination of videofluoroscopy was essential.

Primary intimal sarcoma of the pulmonary artery is a rare disease and there has been no report of any case originating from the pulmonary valve. Recently we experienced a 62 year-old female patient who had a primary intimal sarcoma of the pulmonary valve with distal metastasis. She was brought to medical attention due to exertional dyspnea facial edema productive coughing and general weakness for 1 month. Chest CT and echocardi-ography suggest an acute pulmonary thromboembolism or tumor. Exploration showed a large polypoid mass arising from the pulmonary leaflets and multiple masses on distal pulmonary arteries. We replaced the pulmonary valve and reconstructed the pulmonary artery. She received radiotherapy 1 month postoperatively and now 4 months after surgery she has begun receiving chemotherapy.

Journal of the Korean Pediatric Society 1994;37(7):953-960
Iron deficient state occurs commonly in the athlets, and the cause may be inadequate iron intake, loss of iron from sweat, blood loss of gastrointestinal tract, and hematuria. The age of the athletes ranged from 11 to 17 years old. I messured red blood cell count, hemoglobin, hematocrit, and related hematologic factors in the 32 adolescent female athletes and 21 female controls. a hematologic comparison was perfomed between the athletes and controls. The results obtained were as follows: 1) A value of hemoglobin were 11.6+/-1.4g/dl in the athletes and 12:4+/-0.8g/dl in controls (p<0.05). 2) Hematocrits were 34.1+/-3.4% in the athletes and 37.4+/-2.3% in controls (p<0.05). 3)A value of red bolld cell distribution width values were 13.9+/-2.1% in the athletes and 12.2+/-1.1% in controls (p<0.05). 4) Serum iron was 87.7+/-30.3ug/dl in the athletes and 121.8+/-39.0ug/dl in controls (p<0.001). 5) Total iron binding capacity was 445:6+/-31.8ug/dl in the athletes and 384:6+/-54.2ug/dl in controls (p<0.001). 6) Mean transferrin saturation values were 19.7+/-6.9% in the athletes and 32.5+/-10.8% in control (p<0.001). 7) Ferritin was 14.5+/-10.0ng/ml in the athletes and 33.9+/-13.9ng/ml in controls (p<0.001). 8) The duration of exercise was 4.8+/-2.5 years in the stage III iron deficiency, whil 3.0+/-2.0 years in normal group in iron deficient state (p<0.05).

Journal of the Korean Society of Coloproctology 1998;14(4):701-708
PURPOSE: Bile acids (especially deoxycholate) was known to be toxic and mutagenic on colon epithelium. They proposed at least four mechanisms for the bile acid toxicity. It is the one of these mechanisms that bile acid inhibits the xenobiotic metabolizing enzyme activity (esp glutathione S-transferase, GST). So we measured the cytosolic GST level of colon carcinoma cell lines after deoxycholate exposure whether or not the deoxycholate lowered the cytosolic GST activity. METHODS: Three colon cancer cell lines (LoVo, SW480, HT29) were used for this study. We calculated the cellular toxicity by MTS method. And cytosolic GST activity was measured according to the method as Habig described. For total GST activity, 2.5 mM 1-chloro-2,4-dinitrobenzene was used for substrate, and measured as absorbance in 340 nm. RESULTS: Basal cytosolic GST level for LoVo, SW480, HT29 cell line was 514.59+/-27.01, 291.63+/-38.44 and 344.58+/-47.92 nmol/min/mg cytosol protein. GST level did not changed significantly after 5 days culture without DCA. But GST level was decreased significantly to 128.63+/-21.35, 134.33+/-41.76 and 163.10+/-22.73 nmol/min/mg cytosol protein each cell line after 5 days deoxycholate exposure (p<0.005). CONCLUSION: Cytosolic GST level was lowered significantly after deoxycholate exposure for 5 days. One of the mechanisms of bile acid toxicity for colon cancer cell is proposed to inhibit cytosolic GST activity.

10.Differences between Scores Assessed by Examiners and Examinees on Objective Structured Clinical Examination.
Korean Journal of Medical Education 2009;21(3):279-285
PURPOSE: Self-assessment is important for learning. But, the reliability of self-assessment has long been questioned. We investigated this problem in an objective structured clinical examination (OSCE) setting. METHODS: Forty third-year nursing students who participated in the OSCE were given the same checklist that was used for assessment by the examiners after they finished the OSCE. Then, the scores that were calculated by the examiners and examinees were compared, measuring the average, correlation, difference in score between examinee and examiner, difference in score according to the examinee's level, and Z-score. RESULTS: Scores that were made by the examinees were significantly higher than those of the examiners (average 72.34 vs. 64.03), between which there was a loose positive correlation (r=0.34). The correlation coefficient increased (r=0.62) when a difference in score (examinee-examiner) was compared with the examiner score. When examinees were divided into 3 groups according to their scores, the difference tended to become less as the scores of examinee rose. When the Z-score was compared with the level of the examinee, examinees who had higher scores evaluated themselves lower than the examiners, and examinees with lower scores assessed themselves higher than the examiners. CONCLUSION: According to comparison of averages or correlation analysis, self-assessment by the examinee appeared to be less reliable. But when data were analyzed using difference in score, examinee levels, and Z-score, a certain tendency developed. This pattern may be due to the heterogeneity of the examinee group. Selection of appropriate analysis methods might be important to estabilish the reliability of self-assessment skills.
