PURPOSE: Studies of genetic variation in the prostate-specific antigen (PSA) gene have improved the diagnostic accuracy of PSA for diagnosing prostate diseases in Caucasians. However, the reference ranges and pharmacokinetics of PSA differ significantly according to race. Therefore, we evaluated the association between genetic variations in the PSA promoter area and benign prostatic hyperplasia (BPH) phenotypes in Korean BPH patients. MATERIALS AND METHODS: One hundred twenty-one men were enrolled. The initial serum PSA level, prostate size, and PSA changes at 3 months after treatment with dutasteride were determined. We amplified the promoter region of the PSA gene (nucleotide positions -158 to -356 and -5217 to -5429) and sequenced the products. RESULTS: Three relatively well characterized single-nucleotide polymorphisms (SNPs; rs3760722, rs266867, and rs266868), six uncharacterized SNPs (rs17554958, rs266882, rs4802754, rs2739448, rs2569733, and rs17526278), and one novel SNP (nucleotide position -5402) were found. There were no statistically significant correlations between any of the SNPs of the PSA promoter area and age-adjusted prostate sizes, initial PSA levels, or PSA variations after 3 months of dutasteride treatment. CONCLUSIONS: SNPs in the PSA promoter area were not associated with BPH phenotypes. We could not predict serum PSA changes after dutasteride treatment on the basis of PSA promoter genotype in Korean patients with BPH.

The incidence of gastric cancer is high in old age group and low in young age group, extremely rare in child age. So the diagnosis of gastric cancer in young age is often delayed, and this, with other factors such as poorly differentiated histopathologic tendency and rapid growing nature, makes the prognosis poorer than in other age guoup. Therefore it should always be remembered that the young who has gastric symptom may have malignancy in his stomach in spite of the age. We report a case of early gastric cancer in a 16-years old male with the review of the literature.

A pathological fracture occurs spontaneously or with minimal trauma. The underlying pathological changes may be subtle and the diagnosis not obvious. The two goals in the treatment of pathologic fracture in weight bearing long bones are to provide relief of pain by secure fixation of the fracture and to permit early smbulation and a prompt return to prefracture status. Thirteen cases of pathological fracture were treated during the period from June, 1986 to February, 1988 at Kangnam Sacred Heart Hospital. The results are as follows. 1. Most patients were over 45 of age. 2. Malignancy was the common cause. 3. Most frequent involved site was femur. 4. Occured by trivial trauma such as slip down injury. 5. Satisfactory result by curettage, open reduction and internal fixation, bone graft or bone cement augmentation.

With the goal of providing optimal care to patients, student-centered active learning and the development of clinical competency have become vital components of the education of future physicians capable of sustainably coping with future challenges. However, the shape of future medicine is dramatically changing based on advances in information and communication technology, and the current classroom model seems to have difficulties in fully preparing students for the future of medicine. New trends in teaching and assessment methods include computer-aided instruction, virtual patients, augmented reality, human patient simulations, and virtual reality for the assessment of students’ competency. The digital technologies introduced in medical and dental education include Google Forms to collect students’ answers, YouTube livestreaming, Google Art & Culture (an online art museum), and choose-your-own-adventure as a story-telling technique. Innovations in digital technology will lead the way toward a revolution in medical and dental education, allowing learning to be individualized, interactive, and efficient.

Thirty three patients with mild to moderate essential hypertension were administered ramipril, a new ACe inhibitor, 2.5-5mg once daily for 6 weeks to evaluate the hypotensive efficacy and safety. The results were as follows : 1) The patients consisted of 18 males, 15 females, aged 54 on average and classified as mild in 19 and moderate in 14 patients. 2) At the end of 6 weeks trial, blood pressure dropped 13/6mmHg on average, rewarding 70% effectiveness and normalized below 150/90mmHg in 39%. 3) The most frequent side reaction was dry cough in 5 patients(15%) followed by asthenia, GI trouble, dizziness, edema, eye injection and one case of GPT elevation which normalized after completion of trial. 4) The rating of safety of safety was 79% and of overall usefulness was 73%. In conclusion, ramipril 5mg once daily regimen is well tolerated and effective in the treatment of mild to moderated essential hypertension.

The goal of surgical stone management is to achieve maximal stone clearance with minimal morbidity to the patient. Because of its efficacy, efficiency and low morbidity, extracorporeal shock wave lithotripsy(ESWL) is the first-line treatment for almost all urinary calculi. However, stone clearance after ESWL has been shown to be affected by the stone burden, location, chemical composition and kidney anatomy. Especially, the success rate for ESWL is reduced in lower pole stone(LPS). Percutaneous nephrolithotomy(PNL) and retrograde ureteroscopic intrarenal surgery(RIRS) are alternative treatment options for stones refractory to ESWL such as LPS. Although effective, PNLsubjects the patient to increased morbidity compared to ESWL and RIRS. Because of its low morbidity and relatively high success rate, RIRS for LPS is an attractive treatment modality in selective patients. We report a case of multiple renal pelvis and lower calyceal stones treated with ureteroscopy.
