This study was conducted to assess the relationship between estimated glomerular filtration rate (eGFR) and bone mineral density (BMD) in Korean postmenopausal women with mild renal dysfunction. A total of 328 postmenopausal women who underwent BMD measurement during health check-up was investigated. BMD was measured in lumbar spine (L1-L4), femoral neck, total proximal femur and femoral trochanteric areas by dual energy radiography absorptiometry and renal function was estimated by eGFR using Cockcroft-Gault equation. Of the 328 subjects, 317 (96.6%) had an eGFR > or =60 mL/min/1.73 m2. By using simple linear regression analysis, age, height, weight and eGFR were significantly associated with BMD for the 4 aforementioned anatomic sites, while serum levels of creatinine and blood urea nitrogen did not influence BMD. When multiple regression analyses were applied, age and body weight still had significant associations with BMD at 4 different anatomic sites (P < 0.001). A significant association of eGFR with BMD remained in the lumbar spine, femoral neck and proximal total femur (P < 0.05) but not in the trochanteric area (P = 0.300). Our study suggests that a decline of renal function is associated with lower BMD in the lumbar spine, femoral neck and total proximal femur areas in Korean menopausal women with mild renal dysfunction.

Varicella-zoster virus infection can lead to severe illness in immunocompromised patients. Further the mortality rate of disseminated varicella infection is extremely high particularly in immunocompromised children. We report a case of disseminated varicella infection in a child with acute lymphoblastic leukemia who was receiving chemotherapy, but was initially admitted with only for acute abdominal pain. The patient rapidly developed severe complications, including acute respiratory distress syndrome, acute hepatitis, disseminated intravascular coagulation, and encephalopathy. Acyclovir is a highly potent inhibitor of varicella-zoster virus infection. However, owing to rapid disease progression, it might not be sufficient to control a disseminated varicella infection, especially in immunocompromised patients. Immunoglobulin neutralize virus invasion and suppress viremia, acting synergistically with acyclovir. In this case, early administration of acyclovir and a high-dose of immunoglobulin, combined with mechanical respiratory support, proved adequate for treatment of this severe illness.

PURPOSE: The purpose of this study was to evaluate clinicoradiological outcomes after cementless bipolar hemiarthroplasty in elderly patients with femoral neck fractures. MATERIALS AND METHODS: Eighty hips-all in patients greater than 70 years of age-were followed for more than 2 years after undergoing cementless bipolar hemiarthroplasty with a tapered cementless stem (Lima SPH-C2(R)). The mean age was 76 years, and the mean follow-up period was 37 months. The Harris hip score and postoperative hip pain were analyzed clinically. The radiological results were assessed using various radiological indices. RESULTS: At last follow-up, the mean Harris hip score was 80.2 points. There was one case of significant hip pain. Fifty-five cases (68.7%) showed no decrease in ambulation capacity postoperatively. Radiologically, there were 47 cases (58.7%) of bone ingrowth and 33 cases (41.3%) of stable fibrous fixation. There were no cases of osteolysis, and 30 cases (37.5%) exhibited new bone formation around the stem. All stems were stable without significant alignment change or progressive subsidence. CONCLUSION: Short-term outcomes proved to be satisfactory in elderly patients undergoing cementless bipolar hemiarthroplasty for femoral neck fractures.

PURPOSE: Improved survival of patients with childhood acute lymphoblastic leukemia (ALL) has drawn attention to the potential for late consequences of previous treatments among survivors, including metabolic syndrome. In this study, we evaluated changes in 3 parameters, namely, random blood glucose, body mass index (BMI), and Z score for BMI (Z-BMI), in children with ALL during chemotherapy and after completion of treatment. METHODS: Patients newly diagnosed with ALL from January, 2005 to December, 2008 at Saint Mary's Hospital, The Catholic University of Korea, who completed treatment with chemotherapy only were included (n=107). Random glucose, BMI, and Z-BMI were recorded at 5 intervals: at diagnosis, before maintenance treatment, at completion of maintenance treatment, and 6 and 12 months after completion of maintenance treatment. Similar analyses were conducted on 2 subcohorts based on ALL risk groups. RESULTS: For random glucose, a paired comparison showed significantly lower levels at 12 months post-treatment compared to those at initial diagnosis (P<0.001) and before maintenance (P<0.001). The Z-BMI score was significantly higher before maintenance than at diagnosis (P<0.001), but decreased significantly at the end of treatment (P<0.001) and remained low at 6 months (P<0.001) and 12 months (P<0.001) post-treatment. Similar results were obtained upon analysis of risk group-based subcohorts. CONCLUSION: For a cohort of ALL patients treated without allogeneic transplantation or cranial irradiation, decrease in random glucose and Z-BMI after completion of chemotherapy does not indicate future glucose intolerance or obesity.

PURPOSE: The use of cyclosporine and mini-dose methotrexate (MTX) is a common strategy for graft-versus-host disease (GVHD) prophylaxis in allogeneic transplants. We investigated whether patients who receive fewer than the planned MTX doses are at increased risk for GVHD. METHODS: The study cohort included 103 patients who received allogeneic transplants at the Department of Pediatrics of The Catholic University of Korea College of Medicine, from January 2010 to December 2011. MTX was administered on days 1, 3, 6, and 11 after transplant at a dose of 5 mg/m2 each. Within the cohort, 76 patients (74%) received all 4 doses of MTX [MTX(4) group], while 27 patients (26%) received 0-3 doses [MTX(0-3) group]. RESULTS: Although there was no difference in neutrophil engraftment between the 2 groups, platelet engraftment was significantly faster in the MTX(4) group (median, 15 days), compared to the MTX(0-3) group (median, 25 days; P=0.034). The incidence of grades II-IV acute GVHD was not different between the MTX(4) and MTX(0-3) groups (P=0.417). In the multivariate study, human leukocyte antigen mismatch was the most significant factor causing grades II-IV acute GVHD (P=0.002), followed by female donor to male recipient transplant (P=0.034). No difference was found between the MTX(4) and MTX (0-3) groups regarding grades III-IV acute GVHD, chronic GVHD, and disease-free survival. CONCLUSION: Our results indicate that deviations from the full dose schedule of MTX for GVHD prophylaxis do not lead to increased incidence of either acute or chronic GVHD.

Gasless endoscopic surgery was applied to thyroidectomy. The procedure is a safe and technically feasible method producing good cosmetic results. Compared to the previous endoscopic thyroidectomies, this method is superior with respect to performing hemostasis and minimizing the possible complications resulting from gas insufflating surgery (e.g. hypercapnea or massive subcutaneous empysema). We successfully performed the removal of 37 thyroid tumors of 35 cases by gasless endoscopic surgery without any significant complications. No scars remained in the neck and all patients were satisfied with the cosmetic results. Gasless endoscopic thyroidectomy will become a strong alternative to conventional thyroidectomy for cases of benign thyroid tumors requiring good cosmetic results.

PURPOSE: Due to its high potency against leukemic blasts, our institution has opted for the use of dexamethasone during acute lymphoblastic leukemia (ALL) remission induction, but in our most recent treatment protocol, CMCPL-2005, we shortened the length of steroid treatment from 4 to 3 weeks. We compared both the rates of remission induction and significant complications observed during induction with CMCPL-2005, with those noted for our previous protocol, CMCPL-2001. METHODS: We retrospectively reviewed the records of patients diagnosed with ALL from January, 2001 to December, 2006 at the Department of Pediatrics, St. Mary's Hospital, the Catholic University of Korea. Data concerning age, sex, WBC count at diagnosis, immunophenotype, cytogenetic traits, and risk group were collected for each patient. Results of remission induction treatment were compared between the two patient groups. Infection and other major complications resulting from treatment were investigated according to NCI toxicity criteria. RESULTS: A total of 141 and 88 patients received remission induction under CMCPL-2001 and CMCPL-2005 respectively. In the CMCPL-2001 group, 136 (96%) achieved complete remission while 82 (93%) achieved CR in the CMCPL-2005 group. Patients in the CMCPL-2005 group were more likely to undergo remission induction without experiencing major complications. However, with regards to steroid related toxicities such as infection, no significant differences were noted. CONCLUSION: We shortened the length of steroid administration from four to three weeks, yet found the remission induction rate to be comparable to that of our previous regimen. However, rates of steroid related toxicities such as infectious complications remain unchanged despite shortened exposure to dexamethasone.

BACKGROUND: Annual occurrence of vivax malaria in Republic of Korea (ROK) has exceeded 1,000 cases since 1997. Military system is thought to be a important source of the current outbreak. We collected the information on malaria cases of ROK army, veterans and civilians which occurred in 1999, and analyzed the characteristics of the current outbreak. METHODS: Informations on malaria cases of ROK army, including name, age, sex, rank, force, day of onset, region, etc., were collected through the Office of Surgeon General at Headquarters of ROK army and then analyzed. Informations about malaria cases of veterans and civilians, including age, sex, day of onset, region, etc., were collected through the National Institute of Health and then analyzed. RESULTS:Among a total of 3,628 cases in 1999, 1,085 (29.91%) occurred in the military, 996 (27.45%) occurred in veterans, and 1,547 (42.64%) occurred in civilians. Monthly occurrence reached its peak level at July and had maintained to August. Yeoncheon, Cheolwon and Paju were the highest prevalence region. CONCLUSION: Case occurrence in ROK decreased in 1999 and it was contributed by chemoprophylaxis which has been done since 1997 in the military. It is thought that more attention must be given to protect the further spread of malaria infection.

BACKGROUND: Autoimmune cytopenia (AIC) is a rare complication of allogeneic hematopoietic cell transplantation (HCT). In this study, we reviewed the diagnosis, treatment and response to therapy for pediatric patients with post-HCT AIC at our institution. METHODS: Of the 292 allogeneic HCTs performed from January, 2011 to December, 2015 at the Department of Pediatrics, The Catholic University of Korea, seven were complicated by post-HCT AIC, resulting in an incidence of 2.4%. RESULTS: All seven patients with post-HCT AIC had received unrelated donor transplant. Six of seven patients had a major donor-recipient blood type mismatch. The subtypes of AIC were as follows: immune thrombocytopenia (ITP) 2, autoimmune hemolytic anemia (AIHA) 2, Evans syndrome 3. Median time from HCT to AIC diagnosis was 3.6 months. All but one patient responded to first line therapy of steroid±intravenous immunoglobulin (IVIG), but none achieved complete response (CR) with this treatment. After a median duration of treatment of 15.3 months, two patients with ITP achieved CR and five had partial response (PR) of AIC. Five patients were treated with rituximab, resulting in the following response: 2 CR, 2 PR, 1 no response (NR). Median time to response to rituximab was 26 days from first infusion. All patients are alive without event. CONCLUSION: Post-HCT AIC is a rare complication that may not resolve despite prolonged therapy. Rapid initiation of second line agents including but not limited to B cell depleting treatment should be considered for those that fail to achieve CR with first line therapy.
