PURPOSE: To compare various breath-hold T2 weighted sequences in imaging normal pancreas with a phased-arraycoil. MATERIALS AND METHODS: Eighteen patients without pancreatic disease were studied with breath-hold turbo spinecho (TSE) (TR/TE/ETL, 3500/138/29), TSE with fat suppression (FS-TSE), half-Fourier acquisition single-shot turbospin echo (HASTE) (TE/ETL, 87/128) and HASTE with fat suppression (FS-HASTE) at 1.0T magnet strength and using aphased-array coil. Signal difference-to-noise ratio (SD/N) between the pancreas and peripancreatic fat wasmeasured ; the delineation of the pancreatic border and pancreatic duct, and the amount of artifact were evaluatedby two radiologists who reached a consensus. RESULTS: HASTE showed a higher SD/N than TSE or FS-HASTE (p < 0.01),TSE was superior to FS- TSE or HASTE in the delineation of pancreatic border(p < 0.001). HASTE was superior to TSEin the delineation of pancreatic duct(p < 0.001). TSE showed more artifacts than FS-TSE(p < 0.001) ; HASTE andFS-HASTE showed no artifact. CONCLUSION: TSE is better than HASTE for the delineation of pancreatic margin but HASTE shows less artifacts and a more conspicuous pancreatic duct. Fat suppression decreases artifacts but makes the pancreatic margin indistinct.

BACKGROUND: Essential hyperhidrosis is a pathologic condition caused by excessive secretion of the eccrine sweat glands. This is an embarrassing condition, which severely reduces the quality of life and may result in psychological disturbance. Our purpose was to determine the therapeutic efficacy of oral glycopyrrolate in term of its strength, safety, and side effects. METHODS: Oral glycopyrrolate was given to 104 patients, 53 men and 51 women with a mean age of 24 years. Patients controlled the dosage of glycopyrrolate for a week. Attention was focused on patient satisfaction, onset time, duration, degree of reducing perspiration and side effects. RESULTS: Ninety eight of 104 patients (94%) were satisfied with their improved condition. The most common maximum dose/day was 2 mg. The overall mean onset time was 2.3 hours and the duration of the effect was 7.4 hours. Dry mouth occurred in 40 patients. Sixty eight of patients (65%) experienced reduced excessive sweating caused by oral glycopyrrolate. CONCLUSIONS: The administration of oral glycopyrrolate is a safe and effective method of treating essential hyperhidrosis, and appears to be an acceptable therapeutic option in any form of hyperhidrosis.

PURPOSE: The supply of donor organs does not meet the demand of transplantation. To find a possible way of expanding the donor pool, we have evaluated the risk factors of cadaveric donors that influence the graft survival. METHODS: Between Feb. 1995 and Dec. 1999, we performed 200 cases of cadaveric kidney transplantation. The graft survival rates in 1 yr, 2 yr, & 3 yr are 93.0%, 91.1%, & 89.9%, respectively. We defined the marginal donor as a donor who possesses one of the risk factors of donor age > or = 50, or < or =5 year old (n=18), ICU stay > or =10 days (n=46), history of hypertension (n=30), CPR > or =20 min (n=7), prolonged hypotension (SBP < or =80 mmHg, over 6 hr) (n=40), high dose inotropic support (dopamine > or =20microgram/kg/min, or dobutamine > or =15microgram/kg/min) (n=78), serum creatinine level > or =2.5 mg/dl (n=16), or cold ischemic time > or =12 hr (n=34). We compared graft survival rates between the marginal donor group and the non-marginal donor group, and analyzed risk factors affecting graft survival by univariate and multivariate methods. RESULTS: CPR > or =20 min (71.5%, 71.5%, - vs 93.8%, 91.8%, 90.6%, p=0.027), prolonged hypotension (85.0%, 85.0%, 80.3% vs 95.0%, 92.6%, 92.6%, p=0.028) and serum creatinine > or =2.5 mg/dl (75.0%, 75.0%, 75.0% vs 94.6%, 92.4%, 91.0%, p=0.001) affect graft survival in univariate analysis. There is, However, no risk factor that affects graft survival in multivariate analysis. CONCLUSION: We can increase the supply of donor organs for kidney transplantation by the selective use of high-risk cadaver donor. However, a prospective randomized study including recipient factors is needed to define the acceptable conditions better.

Purpose:
Preimplantation genetic testing for monogenic disorders (PGT-M) has been successfully used to prevent couples with monogenic disorders from passing them on to their child. Charcot–Marie–Tooth Disease (CMT) is a genetic disorder characterized by progressive extremity muscle degeneration and loss of sensory function. For the first time in Korea, we report our experience of applying single nucleotide polymorphism genotyping and karyomapping for PGT-M of CMT disease.
Materials and Methods:
Prior to clinical PGT-M, preclinical tests were performed using genotypes of affected families to identify informative single-nucleotide polymorphisms associated with mutant alleles. We performed five cycles of in vitro fertilization PGT-M in four couples with CMT1A, CMT2A, and CMT2S in CHA Fertility Center, Seoul Station.
Results:
From July 2020 through August 2021, five cycles of PGT-M with karyomapping in four cases with CMT1 and CMT2 were analyzed retrospectively. A total of 17 blastocysts were biopsied and 15 embryos were successfully diagnosed (88.2%).Ten out of 15 embryos were diagnosed as unaffected (66.7%). Five cycles of PGT-M resulted in four transfer cycles, in which four embryos were transferred. Three clinical pregnancies were achieved (75%) and the prenatal diagnosis by amniocentesis for all three women confirmed PGT-M of karyomapping. One woman delivered a healthy baby uneventfully and two pregnancies are currently ongoing.
Conclusion
This is the first report in Korea on the application of karyomapping in PGT-M for CMT patients. This study shows that karyomapping is an efficient, reliable and accurate diagnostic method for PGT-M in various types of CMT diseases.

PURPOSE: The prognosis for patients with stage IV gastric cancer is very poor. However, recently, some studies have reported benefits from a gastric resection for metastatic gastric cancer. This clinical study was performed to evaluate the effectiveness of a noncurative gastrectomy in treating stage IV gastric cancer with hepatic metastasis. MATERIALS AND METHODS: A retrospective analysis was performed on 98 gastric cancer patients who had undergone gastric resection, in spite of hepatic metastasis, between January 1990 and December 1996 at the Department of Surgery in 11 General Hospitals in Korea. RESULTS: The average age was 58 years old, and the male-to-female ratio was 69: 29. The laboratory tests were unable to predict hepatic metastasis. In 54 cases, hepatic metastasis was not identified before the surgery. The most common location of gastric cancer was antrum (72 cases). The most common gross type was Bonmann type III (78 cases). The serosa-exposed cases were 80. The peritoneal seeding was combined in 17 cases. A total gastrectomy was performed in 18 cases and a distal gastrectomy in 80. Lymph-node dissection was performed in 23 Dl, and 51 D2 cases. Hepatic resection was performed in 36 cases, The frequent histologic types were moderately differentiated and poorly differentiated tubular adenocarcinoma. Postoperative adjuvant chemotherapy was done in 70 cases. The complication rate (7%) was low. The median survival time was 15 months, with mean survival time of 18 months. The 2-year and 3-year survival rates were 23%, and 7%, respectively. In the univariate analysis, good survival was closely related to limitation of hepatic metastasis to one lobe, a few metastases to both lobes, negativity of peritoneal seeding and lymph node dissection more than D2 (p<0.05), CONCLUSIONS: An aggressive gastric resection for stage IV gastric cancer with hepatic metastasis might be beneficial in lengthening the survival period. A prospective study is needed, especiaUy one with an exact evaluation and analysis of the quality of life between the gastrectomy and nonresection groups.
