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.

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.

The tracheobronchial histopathologic findings in 7 healthy cats used with high frequency oscillation ventilation (HFOV) were compared with those in 6 cats used with conventional mechanical ventilation (CMV). 4-point, 9-variable scoring system was used to evaluate the injury in the trachea, right & left main bronchi and parenchyma. The following results were obtained; 1) The tracheobronchial tree received HFOV had no significant damage compared with CMV (P>0.05). 2) Intraepithelial mucus loss and emphysema were slightly more prominent in CMV groups. As above results; the tracheobronchial histopathologic difference was not prominent between CMV and HFOV groups received with relatively short period, however, the cellular of function and barotrauma may be more prominent in CMV groups. From now on, as causes of tracheobronchial injury in HFV, interaction between humidification and mechanical trauma considers further study.

Mobius syndrome is a rare congenital disorder characterlzed by facial diplegia and bilateral abducens palsy, which occasionally combinds with other cranial nerve dysfunction, cardiac anomalies, endocrinopathy. Myopathy, peripheral neuropathy and skeletal abnormalities. We report 2 cases of Mobius syndrome; A 6 year old boy showing delayed development, musculo-skeletal anomaly, hypoglossal dysfunction, carpal tunnel syndrome and mild endocrinologic dysfunction, and a 23 year-old lady with only questionable endocrine dysfunction. MRI scans of brain and brainstem are normal and there is no definite electrophysiological evidence of dysfunctions in brainstem on evoked potential blink reflex study. Mental functions look normal in both cases.

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.
