Financial stability is the foremost prerequisite for the continuous growth and development of hospitals. The present study aimed at developing a deterministic model using the factors which affect the hospitals profitability and at discovering which factor affected the hospital profitability. The study conducted questionnaire surveys on all general hospitals, with the exception of special hospitals, with over eighty hospital beds. Of the 274 subject hospitals, 136 of them, consituting 49.6% of the whole, were used in the study. The results are as follow. 1. In the deterministic model, outpatient revenue was affected more by the number of physician visits than by outpatient service intensity. Inpatient revenue was found to be affected more by the number of discharged patients than by inpatient service intensity. However, the increase rate of the service intensity not only contributed in stepping up the operating margin by 4~8% in outpatient and 3~6% in inpatient, but it was statistically significant. 2. Among the factors which determined the operating cost within the deterministic model, the number of patients had a greater impact on the operating cost than the resource consumption per patient. 3. The resource consumption per patient were proved to have the greatest effect on the profitability within the probabilistic model. The management cost per adjusted patient, in particular, was proven to have a statistically significant effect on the profitability in all hospitals.

BACKGROUND: This study was done to identify the prevalence of benign prostatic hyperplasia (BPH) and BPHrelated symptoms among community-dwelling elderly men in Korea. In addition, quality of life and health care-seeking behavior were explored. METHODS: A total of 417 elderly men were surveyed using the IPSS (International Prostatic Symptom Score) and a structured questionnaire on health care-seeking behaviors. RESULTS: The prevalence of BPH was 19.7%. Of those with BPH, 80.3% reported mild symptoms, 13.2% moderate symptoms, and 6.5% severe symptoms. The severity of BPH-related symptoms was significantly correlated with quality of life. Among those with BPH, 42.7% had never consulted with anyone about their symptoms. CONCLUSIONS: BPH has emerged as a serious public health problem in elderly men. Elderly people who experience worse symptoms of BPH have a lower quality of life. Many elderly with BPH do not seek health care, mainly due to misconceptions about BPH. The provision of educational programs for BPH may significantly improve the quality of life of elderly men.

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.

The aim of this study was to evaluate the risk factors of recurrences after their first febrile convulsions in infants and young children. Dlinical studies were made on 187 cases of febrile convulsions who were admitted to the Department of pediatrics of wallace Memorial Baptist Hospital from March, 1990 to December, 1992. 1) 63 cases of 187 cases had recurrences after their febrile convulsions. Thus, the recurrence rate was 33.7%. 2) The male to female ratio was 2.1:1. And there were no significant differences in recurrence rates between sexes. 3) The recurrence rate was significantly higher in those whose initial febrile convulsions were developed before first 18 months of life than those whose initial convulsions were after 18 months of age (49.5% vs. 12.5%). 4) The time interval from initial attack to recurrence was within 12 months in 80% of cases. 5) Our study revealed that the seizure characteristics of the initial febrile convulsion are not important as predictive factors about the probability of recurrences. 6) Among the total 187 cases, family history were present in 52 cases (27.8%). And there were significantly higher recurrence rates if their families show the same history of febrile convulsion (63.5% vs. 22.2%). 7) The risk of recurrence was much higher in patients whose first febrile history of febrile convulsion at the same time.

Background: Liquid biopsy is a useful assay for the diagnosis, treatment, and prognosis prediction of solid tumors and its clinical application is expanding. Therefore, the need for developing an External Quality Assessment (EQA) protocol for liquid biopsy is increasing. In this study, we developed and implemented the liquid biopsy EQA program for the epidermal growth factor receptor mutation. Methods: We validated the feasibility of the protocol using citrate instead of ethylenediaminetetraacetic acid (EDTA). Additionally, we analyzed the homogeneity and stability of the aliquoted quality control (QC) materials. Mutation-positive QC material with four mutations (exon 19 deletion, L858R, T790M, and exon 20 insertion) was used to make two types of QC materials (low and high) and the wild type material was used for the negative controls. If the EQA results showed consensus in more than 80% of the participating laboratories, the results were reported as acceptable or unacceptable. If not, we reported the results as not graded. Results: Citrate showed equivalent performance to EDTA. Highly mutated QC material and mutation-negative QC material passed the homogeneity and stability test, but low-level mutant specimens showed inconsistent results. In total, 11 laboratories participated, and all of them reported consistent results except for low-grade mutant samples. Thus, the evaluation results were acceptable except for low mutation QC material. Conclusions The applicability of liquid biopsy is expanding. To obtain accurate test results, EQA is indispensable. Here, QC materials for liquid biopsy EQA were produced, distributed, and had its results analyzed. This study could be the foundation for further development of liquid biopsy EQA.

PURPOSE: The authors of the present study report a case of phthiriasis palpebrarum treated with petrolatum ointment and tea tree oil in a 12-month-old boy. CASE SUMMARY: A bluish-gray macule and blood clots were found on the central portion of the upper eyelid of a boy who had rubbed his eyelid vigorously 1 week prior. Several 0.5 mm sized brownish-gray nits and 1.6 mm sized lice on the eyelashes were visible and was diagnosed with phthiriasis palpebrarum after light microscopic examination. The nits and lice were gently removed mechanically with the help of a white petrolatum ointment (Vaseline) and the eyelashes were cleaned with 50% tea tree oil. Nits and lice were successfully eradicated without recurrence 10 days after daily treatment with petrolatum ointment and 10% tea tree oil eyelash cleansing.

Two cases of juvenile pernicious anemia in Korean sisters have been followed for 4 years since 7 years and 4 years of age respectively. The symptoms and signs were pale facies, general malaise, sore tongue, anorexia, frequent febrile episodes, macrocytic hyperchromic anemia, thrombocytopenia, multilobulated leucocytes with more than 6 lobules and megaloblastic proliferation in bone marrow aspiration. Dramatic hematological response to the parenteral administration of vitamin B12 with a significantly increased excretion rate of vitamin Bl2 by Schilling test as shown by an increase from 0 to 11.6% in elder sister and from 0 to 5.6% in younger sister with the addition of commercial intrinsic factor were demonstrated. These findings are compatible with the characteristics of juvenile pernicious anemia resulting from defect of Cast1e's intrinsic factor.
