Background/Aims:
To investigate if BK virus (BKV)-specific T cell immunity measured by an interferon-γ enzyme-linked immunospot (ELISPOT) assay can predict the outcome of BK virus infection in kidney transplant recipients (KTRs).
Methods:
We included 68 KTRs with different viremia status (no viremia [n = 17], BK viremia [n = 27], and cleared viremia [n = 24]) and 44 healthy controls (HCs). The BK viremia group was divided into controller (< 3 months) and noncontroller (> 3 months) according to sustained duration of BKV infection. We compared BKV-ELISPOT results against five BKV peptides (large tumor antigen [LT], St, VP1-3).
Results:
BKV-ELISPOT results were higher in three KTRs groups with different BKV infection status than the HCs group (p < 0.05). In KTR groups, they were higher in cleared viremia group than no viremia or BK viremia group. Within the BK viremia group, controller group had higher LT-ELISPOT results compared to noncontroller group (p = 0.032). Also, KTRs without BK virus-associated nephropathy (BKVN) had higher LT, St, VP1, and VP2-ELISPOT results than those with BKVN (p < 0.05).
Conclusions
BKV-ELISPOT assay may be effective in predicting clinical outcomes of BKV infection in terms of clearance of BK virus and development of BKVN.

PURPOSE: The survey aimed to obtain opinions about a proposed implementation of pharmacy skills assessment in Korean pharmacist licensure examination (KPLE). METHODS: A 16-question survey was distributed electronically to 2,738 people including 570 pharmacy professors of 35 pharmacy schools, 550 preceptors from 865 practice sites and 1,618 students who graduated in 2015. The survey solicited responses concerning the adequacy of the current KPLE in assessing pharmacy knowledge/skills/attitudes, deficiencies of pharmacy skills testing in assessing the professional competencies necessary for pharmacists, plans for pharmacy skills tests in the current KPLE, and subject areas of pharmacy practice. RESULTS: A total of 466 surveys were returned. The current exam is not adequate for assessing skills and attitudes according to 42%–48% of respondents. Sixty percent felt that skills test is necessary to assess qualifications and professional competencies. Almost two-thirds of participants stated that testing should be implemented within 5 years. More than 60% agreed that candidates should be graduates and that written and skills test scores can be combined for pass-fail decisions. About 70% of respondents felt that the test should be less than 2 hours in duration. Over half of the respondents thought that the assessor should be a pharmacy faculty member with at least 5 years of clinical experience. Up to 70% stated that activities related to patient care were appropriate and practical for the scope of skills test. CONCLUSION: Pharmacy skills assessment was supported by the majority of respondents.

OBJECTIVE: As the demands of pharmacist's role and quality performance have increased, the verification of pharmacist's ability has been required. In this study, we aimed to select appropriate items for assessment of pharmacist's knowledge, attitude and performance. METHODS: Based on the pharmacist job analysis, we selected duties and tasks in consideration of applying pharmacy practical examination through brainstorming of internal researchers and group discussion with experts. Survey was conducted to evaluate the tasks according to the criteria detailed below: Realistic, Understandable, Measurable, Behavioral and Achievable (RUMBA). The subjects included professors at colleges of pharmacy and instructors of institutional or community pharmacy settings. RESULTS: Nine duties including 41 tasks were drawn for the survey through primary internal researchers. Of the 90 respondents, 95.6% were professors or preceptors who was engaged in practical training, and 62.2% had more than five years of practical experience. As a result of survey and discussion with expert panel, selected seven duties were selected as followings: ‘Patient (customer) reception’, ‘Drug preparation and distribution’, ‘Patient care’, ‘Administration’, ‘Patient counseling’, ‘Non-prescription medication counseling’, and ‘Provision of drug information’. The final 20 tasks from seven duties were chosen to assess skills that a pharmacist should be able to perform. CONCLUSION: This is the first study to select the items that can be included in pharmacist practical examination in the future, based on the RUMBA criteria. As a next step, it is necessary to study how to implement these items.

BACKGROUND: Macrophages are a component of a tumor's microenvironment and have various roles in tumor progression and metastasis. This study evaluated the relationships between tumor-associated macrophage (TAM) density and clinical outcomes in 14 different types of human cancers. METHODS: We investigated TAM density in human tissue microarray sections from 14 different types of human cancers (n = 266) and normal thyroid, lung, and breast tissues (n = 22). The five-year survival rates of each cancer were obtained from the 2011 Korea Central Cancer Registry. RESULTS: Among 13 human cancers, excluding thyroid cancer, pancreas, lung, and gallbladder cancers had the highest density of CD163-positive macrophages (7.0+/-3.5%, 6.9+/-7.4%, and 6.9 +/- 5.5%, respectively). The five-year relative survival rates of these cancers (pancreas, 8.7%; lung, 20.7%; gallbladder, 27.5%) were lower than those of other cancers. The histological subtypes in thyroid cancer exhibited significantly different CD163-positive macrophages densities (papillary, 1.8 +/- 1.6% vs anaplastic, 22.9 +/- 17.1%; p < .001), but no significant difference between histological subtypes was detected in lung and breast cancers. Moreover, there was no significant difference in CD163-positive macrophages densities among the TNM stages in lung, breast, and thyroid cancers. CONCLUSIONS: Cancers with higher TAM densities (pancreas, lung, anaplastic thyroid, and gallbladder) were associated with poor survival rate.

PURPOSE: To investigate whether allelic polymorphism of haptoglobin (Hp) is associated with premature rupture of membrane (PROM), the Hp phenotypes of pregnant women with PROM were analyzed. PATIENTS AND METHODS: The Hp phenotypes of 221 pregnant Korean women (187 control and 34 PROM patients) were determined by benzidine/hydrogen peroxide staining, following native polyacrylamide gel electrophoresis of hemoglobin-mixed sera. The Hp allele frequencies were calculated from the data of Hp phenotypes, and overall association with PROM was evaluated using Pearson Chi-Square test. RESULTS: The polymorphic distribution of the patients cohort who underwent a normal delivery (control group) was similar to that of healthy Koreans. In contrast, however, patients with PROM showed significantly higher occurrence of the Hp 1-1 phenotype than control group (23.5% vs 8.0%). Hp 2-2 phenotype was lower in PROM cohort (38.2%) than in the control group (48.7%). The Hp1 allele frequency in PROM group was significantly higher than that in the control group (0.426 vs 0.297, p = 0.034) with odds ratio of 1.762 (95% CI: 1.038 - 2.991). CONCLUSION: These findings suggest that pregnant Korean women who possess Hp1 allele (expressed as Hp 1-1 phenotype) have higher incidence of PROM than women with Hp2 allele (expressed as Hp 2-2 phenotype). This is the first study that evaluated the significance of Hp polymorphism with respect to the development of PROM.

PURPOSE: Most burn scar contractures are curable with skin grafts, but free flaps may be needed in some cases. Due to the adjacent tissue scarring, local flap is rarely used, and thus we may consider free flap which gives us more options than local flap. However, inappropriate performance of free flap may lead to unsatisfactory results despite technical complexity and enormous amount of effort. The author will discuss the points we should consider when using free flaps in treating burn scar contractures METHODS: We surveyed patients who underwent free flaps to correct burn scar contractures from 2000 to 2007. We divided patients into two groups. The first group was those in which free flaps were inevitable due to exposure of deep structures such as bones and tendons. The second group was those in which free flap was used to minimize scar contracture and to achieve aesthetic result. RESULTS: We performed 44 free flap on 42 patients. All of the flaps were taken well except one case of partial necrosis and wound dehiscence. Forearm free flap was the most common with 21 cases. Most of the cases(28 cases) in which free flaps were inevitable were on the wrist and lower limbs. These were cases of soft tissue defect due to wide and extensive burns. Free flaps were done in 16 cases to minimize scar contracture and to obtain aesthetic outcome, recipient sites were mostly face and upper extremities. CONCLUSION: When using free flaps for correction of burn scar contractures, proper release and full resurfacing of the contracture should be carried out in advance. If inadequate free flap is performed, secondary correction is more challenging than in skin grafts. In order to optimize the result of reconstruction, flap thickness, size and scar of the recipient site should be considered, then we can achieve natural shape, and minimize additional correction.

There are many complications following gastrectomy and one of the most frequent complications is anastomosis site leakage. Postoperative leakage is a serious complication in patients after they undergo gastric surgery. It can lead to the progressive deterioration in the patient's condition and quality of life and the mortality rate is nearly 60%. We encountered a case of a 75 year-old man who had the leakage of the jejunal end of the Roux limb after total gastrectomy. We performed treatment of the leakage endoscopic clipping and detachable snaring. Hemoclips were fixed at the margin of both sides of the lesion. A detachable snare was used to bind both hemoclips, so the interval was made narrow. After snare binding, five hemoclips were used for final closure of the small interval. After treatment, the leakage of the afferent loop end was completely stopped. He resumed an oral intake and was discharged without complications.

PURPOSE: Cardiovascular risk assessment of atherosclerotic arterial occlusive diseases is a critical component of preoperative care. Many indexes have been developed to help identify patients at high risk for perioperative cardiac events. We sought to study guideline implementation and clinical outcomes in cardiovascular risk assessment. METHOD: We studied 75 patients who underwent preoperative cardiac risk assessment between 2003 and 2006 at the Kyung Hee University Medical Center. The American College of Cardiology/American Heart Association (ACC/AHA) guidelines were used to stratify the patients. RESULT: The mean age of patients was 67.9 years. When stratified into risk categories according to the ACC/AHA guidelines, 2 patients was high risk group, 51 intermediate risk group, and 22 low risk group. There were 3 perioperative cardiac complications (4.0%) including 2 mortalities (2.7%). There was a trend toward a higher frequency of cardiac complications when there was discordance with the ACC/AHA guidelines, but there was no significant difference (discordance 7.1%, concordance 0%, P=0.251). The guidelines recommended cardiac testing for 44 patients, but 12 patients (27.3%) were tested. The guidelines did not recommend for 31 patients, but additional cardiac tests were done for 10 patients (32.3%) and mainly associated with low risk group. CONCLUSION: Differences between clinician practice and guideline recommendations existed and did not result in a higher frequency of cardiac complications.

PURPOSE: To evaluate the effectiveness and safety of fentanyl-TTS in the management of radiotherapy induced acute pain and cancer pain treated with radiotherapy. MATERIALS AND METHODS: Our study was open labelled prospective phase IV multi-center study. the study population included patients with more 4 numeric rating scale(NRS) score pain although managed with other analgesics or more than 6 NRS score pain without analgesics. Patients divided into two groups; patients with radiotherapy induced pain (Group A) and patients with cancer pain treated with radiotherapy (Group B). All patients received 25 ug/hr of fentanyl transdermal patch. Primary end point was pain relief; second end points were change in patient quality of life, a degree of satisfaction for patients and clinician, side effects. RESULTS: Between March 2005 and June 2005, 312 patients from 26 participating institutes were registered, but 249 patients completed this study. Total number of patients in each group was 185 in Group A, 64 in Group B. Mean age was 60 years and male to female ratio was 76:24. Severe pain NRS score at 2 weeks after the application of fentanyl was decreased from 7.03 to 4.01, p=0.003. There was a significant improvement in insomnia, social functioning, and quality of life. A degree of satisfaction for patients and clinician was very high. The most common reasons of patients' satisfactions was good pain control. Ninety six patients reported side effect. Nausea was the most common side effect. There was no serious side effect. CONCLUSION: Fentanyl-TTS was effective in both relieving pain with good tolerability and improving the quality of life for patients with radiotherapy induced acute pain and cancer pain treated with radiotherapy. The satisfaction of the patients and doctors was good. There was no major side effect.

OBJECTIVE: The aim of our study was to identify graft, obstetric and maternal outcomes of pregnancies in renal transplant recipients at our center. METHODS: A 14-year retrospective study between January 1990 and December 2003, 224 women 15 to 45 years of age had transplantation and were analyzed the outcomes of pregnancies, obstetric complications and graft function. RESULTS: Thirty-four pregnancies occurred in 21 of 224 patients. The mean age at the time of conception was 29.5 years (21 to 36 years) with a mean interval of 61.9 months (one to 162 months). In the pregnancy outcome, there were the 23 live births (67.6%) included 13 preterm and 10 term deliveries, 3 spontaneous abortions (8.8%), 7 artificial abortions (20.5%) and one case of ectopic pregnancy (2.9%). Obstetric complications were; preeclampsia (39.1%), preterm labor (43.4%), urinary tract infections (38.2%) and gestational diabetes (8.6%). Nine pregnancies within 2 years of transplantation had the permissible obstetric outcomes comparing with the others after 2 years (spontaneous abortion: p=0.77, artificial abortion: p=0.88, live birth: p=0.36). In twelve pregnancies appearing renal dysfunction associated with pregnancy, the abortion rate was increased comparing the others with stable renal function (p=0.006). Pre-pregnancy serum creatinine > or =1.4 mg/dl was associated with increased preterm delivery, but not significant (50.0% vs 28.5%, p=0.30). In graft function, serum creatinine 3~6 postpartum was significantly increased comparing pre-pregnancy levels (p=0.04). Five cases of 7 patients with acute rejection episode associated with pregnancy conceived after 4 years of transplantation. Two-year graft survival after delivery was 95.2% (20/21) and chronic rejection and graft failure was diagnosed in one case at postpartum 14 months. CONCLUSION: These findings suggest that, if the graft function is stable, pregnancy within 2 years after renal transplantation might be safe. Pregnancy does not appear to have adverse effects on long term graft survival.
