Trichilemmal horn(trichilemmal keratosis) is a rare keratinizing tumor that resembles a cutaneous horn. Histologically, it is characterized by an abrupt maturation of keratinocytes into lamellar keratin without the formation of a granular layer. We describe a case of a trichilemmal horn on the right cheek of a 78-year-old woman.

Prurigo pigmentosa is a chror ic pruritic inflammatory dermatosis characterized by erythematous papules in a reticulated pattern that resolve leaving a reticulated, mottled hyperpigmentation and rapidly response to dapsone therapy. Most cases that have been reported are from Japan. We report two cases of prurigo pigmentosa in a 21 year-old female and a 23-year-old female. Histopathologic findings of erythematous papules showed exocytosis, spongiosis, liquefaction degeneration of basal cell layer and perivascular lymphohistiocytic infiltration on the upper dermis. We treated them with dapsone, 100mg daily, which resulted in a remarkable regression of the ery thematous papules and improvenien of pruritus.

Strongylodiasis is universal in distribution but is most abundant in countries with a tropical climate. Although infestation by Strongyloides stercoralis is usually limited to the intestines, dessemination of this helminth in debilitated host can be lead to death with various clinical disorders. characterized by profound malabsorption, diarrhea, electrolyte imbalance, gram negative or opportunistic fungal sepsis, coma and death. Cell-mediated immunity contributing significantly to the control of helminthic infections, may be suppressed by carcinoma, immunosuppressive chemotherapy and use of corticosteroids. Diagnosis of Strongyloidiasis is achieved by an examination of samples of feces, duodenal aspirates and sputum of patients for Strongyloides stercoralis. Treatment of strongyloidiasis is twofold : correction of the immunosuppressive state by withdrawal of immunosuppressive drug, if possible, and vigorous treatment with thiabendazole. Testing for strongyloidiasis is especially recommanded before treating a patients should be monitored for infection by Strongyloides stercoralis and other opportunistic infection. We are reporting a case patient with Strongyloides stercoralis hyperinfection and pulmonary tuberculosis who had been. used corticosteroid for persisting polyarthritis.

BACKGROUND: CYFRA 21-1 is a tumor marker which measures a fragment of cytokeratin 19 expressed by epithelial cells in bronchus. It is known that cytokeratin 19 is abundant in squamous epithelial cell cancer of the lung. However, if the incidence of elevated serum CYFRA 21-1 level in patients with benign lung diseases or pulmonary tuberculosis with severe parenchymal damage is high the specificity of CYFRA 21-1 could be decreased. The purpose of this study is to investigate the changes of serum CYFRA 21-1 according to the degree of parenchymal damage and the usefulness of CYFRA 21-1 for diagnosing possibly combined lung cancer in patients with pulmonary tuberculosis. METHOD: We studied the changes of serum CYFRA 21-1 according to the sputum AFB stain, radiologic manifestation and history of treatment in 81 patients with pulmonary tuberculosis, and 20 healthy persons, 25 patients with lung cancer, as a control group. CYFRA 21-1 concentration in serum was quantified by the immunoradiometry assay(Centocor (R)) RESULT: The results were as follow; Serum CYFRA 21-1 level was significantly lower in patients with pulmonary tuberculosis(1.54+/-1.19ng/mL, p<0.01) as compared to patients with lung cancer( 12.25+/-15.97ng/mL), and was slightly higher than the level in heathy persons(0.90+/-0.49ng/mL) but there was no significant difference. Serum CYFRA 21-1 level was below the cut-off value of 3.3ng/mL in 95 percent of patients with pulmonary tuberculosis but it was above the cut-off value in 64 percent of patients with lung cancer. Serum CYFRA 21-1 level was significantly higher in the initial treatment group(1.91+/-1.55ng/mL, p<0.05) as compared to the treatment failure group (0.92+/-0.30ng/mL). According to the sputum AFB smear, serum CYFRA 21-1 level in patients with negative result was slightly higher than the level in patients with positive result but there was no significant difference. According to the radiologic manifestation, serum CYFRA 21-1 level was significantly higher in patients with infiltrative lesion (2.15+/-1.63ng/mL, p<0.01) as compared to patients with destructive lesion (1.04+/-0.54ng/mL). As the size of cavity or destructive lesion was larger, the level was significantly lower(p<0.05). CONCLUSION: As serum CYFRA 21-1 level was significantly higher in the initial treatment group and patients with infiltrative lesion, it suppose to be closely related with the degree of parenchymal damage of the lung of the pulmonary tuberculosis. However CYFRA 21-1 could be useful method for diagnosing lung cancer even in patients with pulmonary tuberculosis combined with lung cancer because of the fact that it was below the cutoff value of 3.3ng/mL in 95 percent of patients with pulmonary tuberculosis.

Enteric fistulae result from gastrointestinal perforations in which communication is established between the site of perforation and another hollow viscus, potential space, or skin surface. Certain types of enteric fistulae are difficult to demonstrate by conventional radiographic methods, and CT is unique in its ability to demonstrate the extent and nature of extraluminal changes. The purpose of this study is to illustrate the CT findings of enteric fistulae occurring in a variety of abdominal and pelvic organs.

Objective: To investigate the incidence and survival rates of primary uterine carcinosarcoma (UCS) in Korea. Methods: From the Korea Central Cancer Registry, we identified patients diagnosed with primary UCS between 1999 and 2018 and collected their information, including age at diagnosis, Surveillance, Epidemiology, and End Results (SEER) summary stage, and treatment. Age-standardized incidence rates (ASRs) and annual percent changes (APCs) were calculated. Baseline characteristics and overall survival (OS) were compared by study periods, ages, and stages at initial diagnosis. Results: Overall, the incidence rate of primary UCS increased markedly during the time period: ASRs, 0.02 per 100,000 in 1999 and 0.25 per 100,000 in 2018 (APC, 13.9%; p<0.001). No difference in OS was observed between patients diagnosed in 1999–2008 and those diagnosed in 2009–2018 (5-year survival rate, 46.0% vs. 48.6%; p=0.871). Considering the mean patient age at diagnosis of UCS, we divided the study population into 2 groups. Patients aged ≥60 years had a more frequent prior radiation history, received less multi-modality treatment, and showed worse OS than those aged <60 years (5-year survival rate, 42.7% vs. 53.6%; p=0.001). In multivariate analysis, both old age at diagnosis (≥60 years) and the SEER summary stage were identified as independent poor prognostic factors for OS, whereas radiation history before the diagnosis of UCS was not. Conclusion The incidence rate of UCS in Korea increased significantly from 1999 to 2018. Advanced stage and old age (≥60 years) at diagnosis might be poor prognostic factors for survival, but not prior radiation history.

BACKGROUND: The treatment for multi-drug resistant tuberculosis(MDRTB) is encountered to be important clinically, but there are still a few reports about it all over the world. So, we evaluated the outcomes of only chemotherapy for the pulmonary MDRTB retrosptctively. METHOD: We reviewed the clinical courses of 63 patients with pulmonary disease due to M.tuberculosis resistant to rifampin and isoniazid who were under follow-up between March 1996 and June 1996 after hospitalization at our hospital between January 1993 and January 1996. We performed cohort retrospective study for all these patient's records. Their regimens were selected individually and preferably included four medications that they had not been given previously and to which the strain was fully susceptible. RESULTS: The 63 patients(mean age, 43.2 years) had previously received a median 5.1drugs. Fifty two(82.5%) patients responded to chemotherapy(as indicated by negative sputum cultures for at least three consecutive months); eleven patients(17.5%) had no response, as shown by continually positive cultures. In a univariate analysis, an unfavorable response was significantly associated with greater number of resistant drugs before the current courses of therapy(relative risk 21.5; 95 percent confidence interval, 1.2-3.0; p<0.05). The mean period of follow-up was seventeen months. There was no relapse subsequently among the patients with responses. There was no death related to tuberculosis. CONCLUSION: In this report from National Masan Tuberculosis Hospital in Korea, multi-drug resistant pulmonary tuberculosis responded relatively well to carefully selected regimens.

This epidemiological study was carried out to investigate the sources of infection and modes of transmission of an outbreak of rubella that occurred among male high school students in Kyongju in march, 1996. 770 male students(286 third grade, 262 second grade, 222 first grade students) were selected as the study subjects. A questionnaire was completed by the subjects. The anti-Rubella antibodies IgM and IgG were examined and tested by ELISA on all sera from 770 students and the environmental status of class rooms, the dormitory conditions and study rooms were tested. The positive IgM result rate was 17.8% and when the IgM negative was combined with IgG positive the results was 74.9%. IgM IgG negative rates were 7.3%, however, out of a total 770 students. Amongst the older students, the IgM positive rate showed an increase(p<0.01). Out of 137 cases(with a cummulative incidence rate of 71.0%), there were 97 apparant cases(cummulative incidence rate 50.3%) and 40 inapparent cases(cummulative incidence rate 20.7%). Again, the cummulative incidence rate showed an increase in the older students(p<0.04). In the apparent cases, major symptoms included eruption(96.9%), fever(85.6%), lymphadenitis(82.5%), generalized aches and muscle tenderness(76.3%), and a sore throat(61.9%). These symptoms lasted anywhere from 2 degrees =/ 13 days, the average duration being 4 days in length. Initially, there were 9 people on third grade and suspected origin was from more than 2 external sources. It progressed from the upper grades down to the lower grades. In dormitory students, the cummulative incidence ratio was 1.70 and 1.78 amongst study room students.

This study was conducted to investigate the cause and magnitude of food poisoning among residents and visitors for a birthday party in a rural area of Kyongju city in september, 1996. The total subjects were 137 persons, 119 residents(53 males, 66 females), including 7 hospitalixed patients and 18 visitors(8 males, 10 females). The investigation consisted of an interview survey, a study on clinical characteristics for the patients hospitalized, bacteriological examinations of the underground water and microbiologic examinations on microbes isolated from the patients. The population at risk was 59 persons(24 males, 35 females). The attack rate was 50.0%(12 cases) for males, 48.6% for females(17 cases). The cases were distributed evenly for all age groups. The attack rates for each party-food and possible fooe groups were not significantly different. Most clinical symptoms were significantly more frequent among cases than non-ases: abdominal pain(73.1%), diarrhea(73.1%), chilliness(69.2%), fever(65.4%), anorexia(61.5%), nausea(53.8%), general weakness(50.0%) and dizziness(50.0%) were the major symptoms among the cases. The admission rate among the cases was 24.1%(1 male, 6 females). In the stool cultures, Salmonella species group D was isolated from 6 persons of 85 examinees. It was identified as Salmonella enteritidis by serological diagnosis. The samples of underground water were assessed Enon-compatible for drinking in 10 wells(83.3%) of this rural area and it was suggested that it could have been contaminated from cattle feces. There were two wells in the party house, one of them was contaminated by bacterias including E. coli. The contaminated water was stored in a water tank located on the rooftop. This water was used for dish washing and cooking. Wd concluded that the cause of this epidemic was the underground water contaminated by Salmonella enteritidis from guman carriers or domestic animal carriers.
