BACKGROUND/OBJECTIVES: This study aimed to investigate the association of dietary patterns with overweight risk and all-cause mortality in pediatric cancer patients. SUBJECTS/METHODS: Prospective cohort study was undertaken; 83 cancer patients admitted to the pediatric cancer ward at a university hospital in Seoul were included and followed for obesity and death over 24 months. Food consumption data were collected from patients using validated meal order sheets for breakfast, lunch, and dinner at the pediatric cancer ward over 3 days. Using principal component analysis, three dietary patterns were derived from 29 food groups. RESULTS: Eighteen deaths occurred among the patient cohort during the follow-up period. The “spicy & fried meat and fish” dietary pattern was positively associated with overweight risk at both baseline [odds ratio (OR) = 4.396, 95% confidence interval (CI) = 1.111-17.385, P for trend = 0.023] and after 6 months (OR = 4.088, 95% CI = 1.122-14.896, P for trend = 0.025) as well as all-cause mortality (hazard ratios = 5.124, 95% CI = 1.080-24.320, P for trend = 0.042), when comparing the highest and lowest tertiles after adjusting for covariates. The “fish, egg, meat, and fruits & vegetables” dietary pattern was associated with lower overweight risk after 24 months (OR = 0.157, 95% CI = 0.046-0.982, P for trend = 0.084). CONCLUSION: The results imply that dietary patterns might be associated with weight gain and premature death among pediatric cancer patients.

Survival rates of preterm infants have improved in the past few decades, and central venous catheters play an important role in the intensive medical treatment of these neonates. Unfortunately, these indwelling catheters increase the risk of intracardiac thrombosis, and they provide a nidus for microorganisms during the course of septicemia. Herein, we report a case of persistent bacteremia due to methicillin-resistant Staphylococcus aureus in an extremely low birth weight (ELBW) infant, along with vegetation observed on an echocardiogram, the findings which are compatible with a diagnosis of endocarditis. The endocarditis was successfully treated with antibiotic therapy, and the patient recovered without major complications. We suggest a surveillance echocardiogram for ELBW infants within a few days of birth, with regular follow-up studies when clinical signs of sepsis are observed.

BACKGROUND/AIMS: Sorafenib is the standard treatment for patients with advanced hepatocellular carcinoma (HCC). We aimed to investigate the prognosis predictors and the role of second-line cytotoxic systemic chemotherapy (CSC) in patients with advanced HCC after sorafenib discontinuation in the pre-regorafenib era. METHODS: From 2007 to 2015 in the pre-regorafenib era, the medical records of 166 HCC patients, who had permanently discontinued sorafenib, were retrospectively reviewed. For further analysis of survival factors after sorafenib treatment failure, we compared the survival of patients who had maintained liver function after second-line treatment with the best supportive care (BSC) group and selective BSC (SBSC) group. RESULTS: After discontinuation of sorafenib, median overall survival (OS) was 2.8 (1.9–3.7) months. The OS in patients who discontinued sorafenib due to adverse effect, progression, and poor clinical condition were 5.5 (2.4–8.6), 5.5 (2.2–8.9), and 0.9 (0.5–1.3) months, respectively (P<0.001). The independent predictive factors of survival after sorafenib failure were serum level of bilirubin and albumin, α-fetoprotein, discontinuation cause, and second-line CSC. In comparison with survival between second-line CSC and BSC group, the CSC group showed better survival outcome compared to the BSC group (10.6 vs. 1.6 months, P<0.001) and SBSC group (10.6 vs. 4.2 months, P=0.023). CONCLUSIONS: The survival after sorafenib failure in patients who discontinued sorafenib due to progression and adverse effects was significantly better than in those who discontinued treatment due to clinical deterioration. In the pre-regorafenib era, patients who received second-line CSC showed better survival than those who received only supportive care after sorafenib failure.

Catastrophic neurological events can occur rarely in anesthetic recovery period and they must be quickly diagnosed. We report here on a spontaneous intracerebral hemorrhage (SICH) that developed during the anesthesia recovery period in a 52-year-old man who had undergone uneventful orthopedic surgery. He had predisposing factors including 25 year history of heavy alcohol consumption and smoking. The risk of spontaneous intracerebral hemorrhage following non-cardiovascular and non-neurovascular surgery is exceedingly small during the anesthesia recovery period, especially for a patient with no history of hypertension and coagulopathy. We also describe the differential diagnosis of an altered mental status that occurs during anesthetic recovery period.

Graft-versus-host disease (GVHD), a life-threatening complication after bone marrow transplantation (BMT), is induced by activation of alloreactive donor T cells. Our previous study demonstrated that transplantation of myeloid differentiation factor 88 (MyD88)-deficient knockout (KO) bone marrow (BM) resulted in aggravation of GVHD. Here, to understand the cellular mechanism, we performed longitudinal in vivo imaging and flow cytometric analyses followed by transcriptome and functional examination of donor MyD88-KO BM progenies in GVHD hosts, using a major histocompatibility complex-matched but minor histocompatibility antigen-mismatched C57BL/6→BALB.B model. In GVHD hosts with MyD88-KO BMT, donor BM-derived CD11b+Gr-1+ cells were found to undergo cell death, a fate significantly different from the explosive expansion shown by the wild type (WT) counterparts, and also from the moderate expansion of the WT or MyD88-KO BM-derived cells in non-GVHD hosts. It was also revealed that MyD88-KO CD11b+Gr-1+ cells preferred differentiation into CD11c+ dendritic cells (DCs) to expansion as myeloid-derived suppressor cells in GVHD hosts or in high inflammatory in vitro conditions. These CD11c+ DCs comprised the majority of MyD88-KO CD11b+Gr-1+ apoptotic cells in GVHD hosts. Their ability to cross-present alloantigens of host origin contributed to the enhancement of T cell alloreactivity, causing GVHD aggravation and eventually death through the killing function of activated T cells. These results provide insights into the roles of MyD88 in myelopoiesis of donor BM and the protective effects in GVHD hosts, helpful information for development of a strategy to control GVHD.

Background/Aims: To prevent the perinatal transmission of hepatitis B virus (HBV) from mother to child, administration of an antiviral agent during pregnancy has been attempted in women who are either hepatitis B e antigen positive or have a high viral load. In this systematic review and meta-analysis with randomized controlled trials, we analyzed the efficacy and safety of tenofovir disoproxil fumarate (TDF) in preventing the perinatal transmission of HBV in pregnant women who have high HBV DNA titers. Methods: Multiple comprehensive databases (PubMed, EMBASE, and Cochrane databases) were searched for studies evaluating the efficacy of TDF for the prevention of perinatal transmission of HBV. Results: Two studies (one open label study and one double blind study) were included and analyzed. Intention-to-treat analysis (527 pregnancies) showed that the preventive effect of TDF was not significant (odds ratio [OR], 0.53; 95% confidence interval[CI], 0.13 to 2.17; p = 0.38, I2 = 81%). However, the per-protocol analysis showed that TDF significantly reduced perinatal transmission (OR, 0.10; 95% CI, 0.01 to 0.77; p = 0.03, I2 = 0%). There was no significant difference between the TDF group and the control group with respect to maternal and fetal safety outcomes. Conclusions In pregnant women who have high HBV DNA titers, TDF can reduce the perinatal transmission from mother to child without significant adverse events.

BACKGROUND: Lung cancer is the leading cause of cancer deaths in Korea and the number of lung cancer deaths is increasing. The higher response rates, decreased toxicity and improved performance status of the first-line treatments have resulted in an increased number of patients becoming candidates for second-line therapy. Several new anti??neoplastic agents, including gemcitabine, docetaxel and paclitaxel, have recently demonstrated second-line activity. This phase II study evaluated the efficacy and toxicity of gemcitabine and vinorelbine as combination chemotherapy for Korean patients with NSCLC as a second-line treatment. METHODS: Sixty response-evaluable patients were enrolled from December 2000 to July 2003. We conducted a phase II study of a combination gemcitabine and vinorelbine chemotherapy for patients with histologically confirmed NSCLC that was stage IIIB and IV disease at the time of diagnosis, and the disease had progressed onward or the patients had relapsed after first-line platinum-based chemotherapy. They were treated with intravenous gemcitabine 1000mg/m2 and intravenous vinorelbine 25mg/m2 on days 1 and 8. This chemotherapy regimen was repeated every 3 weeks. RESULTS: A total of 215 cycles of treatment were given and the mean number of cycles was 3.6 cycles. All the patients were evaluable for the toxicity profile. The response rate was 10% according to the WHO criteria.?The median progression free survival was 3.8 months and the median survival time was 10.1 months. The 1-year survival rate was 32.9%. Grade III and IV neutropenia were seen in 20 (33.3%) and 7 (11.7%) patients, respectively. CONCLUSION: The combination of gemcitabine and vinorelbine is active and well tolerated as a second-line therapy for patients with advanced nonsmall cell lung carcinoma.

Iron supplements such as ferrous sulfate tablets are usually used to treat iron-deficiency anemia in some elderly patients with primary neurologic disorders or decreased gag reflexes due to stroke, senile dementia, or parkinsonism. While the aspiration of ferrous sulfate is rarely reported, it is a potentially life-threatening condition that can lead to airway necrosis and bronchial stenosis. A detailed history and high suspicion of aspiration are required to avoid delays in diagnosis and treatment. The diagnosis can be confirmed by bronchoscopic examination and a tissue biopsy. Early removal of the aspirated tablet prevents acute complications, such as bronchial necrosis, hemoptysis, and lobar consolidation. Tablet removal is also necessary to prevent late bronchial stenosis. We presented the first case in Korea of a ferrous sulfate tablet aspiration that induced severe endobronchial inflammation.
