PURPOSE: Prostate specific antigen (PSA) is a test with relatively low specificity used for determination of risk for prostate cancer. PSA velocity (PSAV) has been used as a complimentary test. We investigated the association of PSAV with age and an initial PSA. MATERIALS AND METHODS: We enrolled 989 healthy men with initial PSA of 4.0ng/ml or lower. The PSA levels were measured at intervals of at least 12 months. We analyzed the influence of age and initial PSA on the PSAV. RESULTS: PSAV was directly correlated with age and the initial PSA. The initial PSA was not correlated with the PSAV when adjusted by age (r=0.009, p=0.773); age was correlated with PSAV when adjusted by initial PSA level (r=0.276, p<0.001). The mean PSAV in cases with initial PSA of 2.1-4.0 ng/ml was significantly greater compared to the cases with an initial PSA of 0-2.0 ng/ml (p<0.01). The ratio of the men with a PSAV greater than 0.75 ng/ml/year was significantly higher in cases with an initial PSA of 2.1-4.0 ng/ml (p<0.05). CONCLUSIONS: PSAV is associated with age and an initial PSA level in healthy Korean men. Men with initial PSA of 2.1-4.0 ng/ml had an abnormal PSAV in high proportion, and therefore annual follow up PSA would be useful for the early detection of prostate cancer in these cases.

Atrial septal defect is one of the most common congenital heart diseases in adult, of which absolute causes is not confirmed, but explained by multifactorial inheritance. In Korea, there has been no case report of atrial septal defect in identical twins in spite of some reports of atrial septal defect in relatives and twins in other countries. We present a first case of atrial septal defect in identical twins whose mother had no infection or medication history during pregnancy.

Infantile hemiplegia is the end state of various pathological conditions affecting the cerebral hemisphere before or during birth, or in first few years of life. In 1950, Krynauw first reported that total hemispherectomy could be carried out with beneficial results for infantile hemiplegia with uncontrollable convulsion, temper tantrum and mental deficiency. Hemispherectomy is not suitable for all cases of infantile hemiplegia, but is seems clear that it should be undertaken in any case of established infantile hemiplegia with fits which cannot be controlled by drugs, or in which there is backwardness or deterioration in the patient's intellectual or emotional state. We have recently experienced a 8-year-old boy who was suffering left hemiplegia with intractable epilepsy. Both carotid angiogram and pneumoencephalogram showed right cerebral hemiatrophy. After right hemispherectomy intractable seizure was controlled and personality disorder disappeared completely. But left hemiplegia wasn't definitely improved.

BACKGROUND: The amount of interference due to hemolysis, bilirubin, and lipemia can be measured on the AU5800 autoanalyzer (Beckman Coulter, USA) by spectrophotometry. This is reported as semi-quantitative indices, specifically H-index, I-index, and L-index, respectively. In this study, we evaluated the impact of interference using chemistry assays and established the concentration of interfering substances and HIL-index above which analytically significant interference exists, according to CLSI guidelines C56-A and EP7-A2. METHODS: Pooled sera including different concentrations of analytes were prepared and mixed with hemoglobin, bilirubin, or Intralipid. These samples were then tested for 35 clinical chemistry analytes by AU5800 and the bias based on interferent concentrations was computed. The interferent concentration above which significant interference exists was calculated from the 50% within-subject biological variation (desirable analytic goal), and the corresponding index was assigned. RESULTS: Among 35 items evaluated, interference was detected for 12 analytes by hemoglobin, 7 analytes by bilirubin, and 12 analytes by Intralipid. We proposed HIL-index₁ and HIL-index₂ for each analyte according to 2 different medical decision levels. HIL-index₁ and HIL-index₂ were considered more reasonable criteria than the HIL-index from the manufacturer's technical document (HIL-index(TD)). This is because HIL-index(TD) was empirically set to 5% or 10%, and had a wide tolerance range, which was not sufficient to reflect the presence of interference, compared to HIL-index₁ and HIL-index₂. CONCLUSIONS: We have demonstrated hemoglobin, bilirubin, and Intralipid interferences according to CLSI guidelines using the desirable analytic goal. Our results provide applicable information for Beckman Coulter automated chemistry analyzers.

STUDY OBJECTIVE: determine the level of medical care required for mass gatherings and describe the types of medical problems encountered in a religious mass gathered ceremony. DESIGN: Standard charts and a four-tiered triage system(minor, moderate, urgent, and emergent) were developed before the event. The triage system was applied to each chart retrospectively by a single emergency physician. SETTING: Medical staff(10 physicians,13 nurses,1 pharmacist, and 54 first-aid attendants) were based in 8 advanced life support (ALS) clinics. INTERVENTIONS: First-aid attendants referred patients to the clinics, where nurses conducted initial assessments and referred patients to physicians at the venue. Three ambulances were stationed at the venues. RESULT: 22 trauma patients were developed and 183 medical complaints were encountered. Only 7 urgent medical problems were encountered.

Recently therapeutic efficacy of stomach cancer was greatly improved due to early diagnosis and irnproved diagnostic and therapeutic modalities. Especially in early gastric cancer, 5 year survival rate is near 100%. Recarrence of early gastric cancer after curative surgery is rarely reported. Recently authors experienced one case of recurrent stomach cancer arising from remmnant stomach 14 years after gastrectomy of EGC type I(m), so we reports it here with review of literatures.
