BACKGROUND: The number of patients of doxylamine overdose has increased, but there were little clinical reports. The purpose of this study is review the patients of doxylamine overdose for aid clinical decision making of patients disposition. METHODS: We reviewed medical records of patients who ingested doxylamine succinate retrospectively from Jan. 1, 1996 to Dec. 31. 1996. Data that was recorded were followed: age, sex, psychiatric history, amounts of ingestion, time interval from ingestion to arrival to hospital, initial vital signs and symptoms, EKG, chest PA, Lab. findings, treatment, patients disposition, length of hospital stay, complication. RESULTS : 1) Total number of patients was ninety and average dosage of ingestion was 1062mg. 2) Tachycardia was the most frequent anticholinergic symptom(46%). 3) Routine lab. findings was not abnormal except one patient who was diagnosed as Rhabdomyolysis. 4) Gut decontamination was performed in patients who had arrived at hospital in 2-3 hours, and who had ingested large dose of drug. 5) Five patients were admitted to Psychiatric dept. and one patient was admitted to emergency dept. for treatment of rhabdomyolysis. 6) The mean duration of hospital stay was 6.5 hours. CONCLUSION: The patients who ingested overdose of doxylamine was managed safely in emergency department, but we should warn against the possibility of rhabdomyolysis.

BACKGROUND: Urinalysis is a useful laboratory test in the diagnosis of various diseases. In sampling for the urinalysis, there is much concern about contamination that can lead to misdiagnosis in the mid-stream urine sampling method. We conducted this study to determine, in terms of concordance of results and contamination in culture, whether there was any superiority in mid-stream sampling methods with or without disinfection measures compared to the catheterization method. MATERIALS AND EMTHODS: We used three kinds of urine sampling methods sequentially, mid-stream non-clean catch, mid-stream clean catch, and catheterization, for ambulatory, non-pregnant, non-menstruating female patients who visited NHIC Ilsan Hospital emergency department during a one-week period in September 2001. Each sample was electrophotometrically analyzed for leukocyte esterase, nitrite, and blood by using a reagent strip and was cultured immediately or after overnight refrigeration. RESULTS: Of the 41 patients, 9 had culture-proven urinary tract infections. The concordance rates(kappa) for nitrite, blood, and leukocyte esterase were 0.875, 0.403, and 0.406 between non-clean catch and catheterized samples and 0.875, 0.481, and 0.560 between clean catch and catheterized samples, respectively. The contamination rate of the non-clean catch, the clean catch, and the catheterized samples were statistically different: 51.2%, 29.3% and 0%, respectively. CONCLUSION: We found that cleaning with disinfectant was effective for reducing the contamination rate, even though the best urine sampling method for zero contamination was catheterization. We recommend considering cost, patients' comfort, an acceptable threshold for contamination, and the necessity for a culture before choosing a urine sampling method for women who visit the emergency department.

PURPOSE: In 2000, the American Heart Association and International Liaison Committee on Resuscitation published guidelines for CPR (Cardiopulmonary Resuscitation), and these guidelines were revised in 2005. Many physicians perform CPR differently than suggested by these guidelines. We investigated guideline conformation rates for CPR by non-emergency physicians. METHODS: From January 1st, 2005, to December 31st, 2005, and from January 1st, 2007, to September 30th, 2007, 103 in-hospital CPR cases were enrolled. We separated the 103 cases into two groups: 2005 patients and 2007 patients. Fifty-two cases in the 2005 group and 51 cases in the 2007 group were enrolled. The defibrillation method, defibrillation energy, epinephrine use, and atropine use were analyzed. RESULTS: Nineteen cases (82.6%) in the 2005 group and three cases (21.4%) in the 2007 group were performed using the appropriate defibrillation method (p=0.0002). Seventeen cases (73.9%) in the 2005 group and four cases (28.6%) in the 2007 group received the appropriate defibrillation energy (p=0.0069). Seven cases (14.0%) in the 2005 group and 16 cases (32.0%) in the 2007 group used the appropriate epinephrine dose (p=0.0325). Fourteen cases (28.0%) in the 2005 patient group and 14 cases (29.2%) in the 2007 patient group used the appropriate atropine dose (p=0.8983). CONCLUSION: Although CPR guidelines were renewed in 2005, many physicians do not follow these guidelines. We suggest that adequate information, education, feedback, and further study are needed for guideline conformation.

Purpose: We assessed the extent of silicone oil (SO) emulsification using ultra-wide-field fundus photography (wFP) and the reflective ratios of swept-source optical coherence tomography (SS-OCT). Methods: We retrospectively enrolled 51 eyes of 51 patients who underwent intravitreal SO tamponade with vitrectomy. Two weeks after SO tamponade and immediately before SO removal, ultra-wide-field fundus photography and SS-OCT were performed. Based on the numbers of emulsified droplets in the ultra-wide-field fundus photographs, SO emulsification was qualitatively graded from 0 to 4. Reflective ratios were calculated by dividing the OCT reflectivity of the optic cup by the OCT reflectivity of SO near the retinal surface. We analyzed the changes in the SO emulsification grade and the reflective ratio over time (RR2/RR1). Results: The SO emulsification grade revealed by ultra-wide-field fundus photography was 2.12 ± 1.29, and the mean SS-OCT RR2/RR1 value was 1.14 ± 0.22. A longer duration of SO tamponade was associated with a higher emulsification grade on ultra-wide-field fundus photography and an increase in the RR2/RR1 value (both p < 0.01). We found a significant correlation between the SO emulsification grade on ultra-wide-field fundus photography and the SS-OCT RR2/RR1 (p = 0.028). Conclusions Ultra-wide-field fundus photography and SS-OCT can be used to determine objectively the extent of SO emulsification; this may indicate the appropriate SO removal time any complication.

PURPOSE: The purpose of this study was to examine the academic achievement of the first year medical students at Gachon University of Medicine and Science based on their characteristics (i.e. age, gender, and academic degree types (bachelors/masters), field of major (biology/ non-biology), and admission variables (i.e. MEET, GPA, attitude, interview, and English test). METHODS: The admission scores and demographic information were obtained from 39 students who had entered the university in 2005. T-test was used to examine the differences in academic achievement according to the students' characteristics. Correlations between admission variables and academic achievements were examined while multiple regression analysis was used to decipher the influence of students' characteristics and admission variables on the academic achievements. RESULTS: This study showed that the academic achievements differed significantly depending on degree level, age, and field of study, but not gender. It was also found that both the Nature Science Reasoning (NSR) of MEET subscale score and GPA score correlated significantly with academic achievement in the first year students. Attitude, interview, and English test scores did not correlate significantly. The result of the multiple regression analysis revealed that NSR 1 and 2, field of major, and age accounted for a substantial amount of the variance in academic achievement. CONCLUSION: Students with higher scores in NSR 1 and 2 who majored in biology-related fieldsand who are younger tend to do better academically in their first year of medical school. The results of this study may be helpful to graduate medical schools in designing effective admissions strategies for recruiting students, as well as, in planning the curriculum to improve the academic achievements of medical students.

OBJECTIVES: To determine the impacts of Diagnosis-Related Groups/Prospective Payment System (DRG/PPS) on the quality of care in cases of Cesarean section and to describe the policy implications for the early stabilization of DRG/PPS in Korea. METHODS: Data was collected from the medical records of 380 patients who had undergone Cesarean sections in 40 hospitals participating in the DRG/PPS Demonstration Program since 1999. Cesarean sections were performed in 122 patients of the FFS(Fee-For-Service) group and 258 patients of the DRG/PPS group. Measurements of quality used included essential tests of pre- and post-operation, and the PPI(Physician Performance Index) score. The PPI was developed by two obstetricians. RESULTS: Univariate analysis demonstrated significant differences in PPI scores according to the payment systems. With respect to the mean of PPI scores, a higher score was found in the DRG/PPS group than in the FFS group. However, the adjusted effect did not show significant differences between the FFS group and the DRG/PPS group. CONCLUSION: This study suggested that the problem of poor quality may not be related to the implementation of DRG/PPS in Cesarean section. However, this study did not consider the validity and reliability of the process measurement, and it did not exclude the possibility of data omission in medical records.

The urogenital tract manifestations of acquired immune deficiency syndrome (AIDS) include the entire array of voiding symptoms; infections, neurogenic bladder problems, impotence, infertility, neoplasma and AIDS associated renal syndromes. Tuberculosis occurs in approximately 4% of patients with AIDS, and involves at least one extrapulmonary site in nearly 50% of cases. However, tuberculous infection of the testicle in AIDS is rarely seen. Herein, we report a case of tuberculosis epididymoorchitis, which developed as a result of reactivation in an AIDS patient. To the best of our knowledge, this is the first reported case of AIDS presenting as tuberculous epididymoorchitis in Korea.

Extrapelvic endometriosis is a fairly rare phenomenon. The majority of extrapelvic endometriosis involves scar tissue following obstetric or gynecologic procedures. Abdominal wall endometriosis secondary to cesarean section is a very rare condition, being reported in less than 0.5% of patients undergoing cesarean section. It has a distinct presentation and treatment. An abdominal mass with noncyclical symptoms is a common presentation. Imaging techniques are nonspecific and needle biopsy may confirm the diagnosis. Wide excision is the treatment of choice for abdominal wall endometriosis as well as for recurrent lesions. A patient with a history of cesarean section presented with a painful, enlarging mass. The pain was cyclic and aggravated just prior to menstruation. The patient was treated with surgical scar excision pathologically confirmed as endometriosis. We present this case with a brief review of literature.
