Purpose:
Despite the recent success of Bruton’s tyrosine kinase (BTK) inhibitors for the treatment of Waldenstrom macroglobulinemia (WM), their indefinite treatment duration ultimately tantamount to substantial financial and emotional burden. On the other hand, fixed duration of proteasome inhibitors (PI) have shown rapid and reasonable response in WM treatment. Despite the well-known synergism between PI and immunomodulatory drugs (IMiD), there is no trials evaluating such combination in WM.
Materials and Methods:
Based on above, we designed this phase II study to investigate the efficacy and safety of 6 cycles of 28-day bortezomib-thalidomide-dexamethasone (VTD) regimen for treatment-naïve WM.
Results:
A total of 15 patients were enrolled: major response rate was 64.3%, and overall response rate was 78.6%. During the median follow-up of 41 months, median progression-free survival (PFS) was 13 months and overall survival 40 months. For responders, median duration of response was 13 months and median PFS 19 months. The most common adverse event (AE) of any grade was constipation (57.1%). The most common grade ≥ 3 AE was anemia (21.4%).
Conclusion
All in all, we hereby provide proof-of-concept that PI + IMiD may be an attractive backbone for fixed duration treatment. It should be noted that granting the same level of access to newer drugs globally is virtually impossible. Thus efforts to develop regimens using readily available drugs to yield similar or adequate treatment outcomes should not be disregarded. In this sense, we believe our study holds its place for its novelty and eloquently addresses achieving the daunting societal quest of health equity.

PURPOSE: This study investigated factors affecting recurrent wheezing in infants, focusing on whether or not respiratory syncytial virus (RSV) infections in children <3 years of age induce recurrent wheezing later in life. METHODS: The inclusion criteria were children <3 years of age who were hospitalized for an RSV infection from January 2006 to December 2009. We evaluated lateral flow immunochromatography (RSV Respi-Strip test). Subjects with at least three episodes of physician-verified wheezing were defined as recurrent wheezers. A group of 79 children hospitalized with RSV infections were compared with a matched control group. The following data were collected: age, gender, admission duration, gestational age, obesity, history of atopic dermatitis, parental history of allergic diseases, exposure to passive smoking, exposure to indoor animals, and daycare attendance. RESULTS: Rates of obesity and exposure to passive smoking were significantly higher in the RSV group than those in the control group. The frequency of recurrent wheezing in the RSV group (39.2%) was higher than that in the control group (10.1%). Compared to the control group, recurrent wheezing occurred 5.76 times more often in the RSV group, 2.49 times more often in males, and 2.41 times often in patients with a parental history of allergic diseases. CONCLUSION: The results demonstrated that RSV infection is significantly associated with recurrent wheezing, and that the risk is higher in male children and in children with a parental history of allergic diseases.

PURPOSE: Febrile convulsions are a common pediatric neurological disease, and it is important to prevent such a disease by controlling the risk factors that may recur. A recent report states that influenza virus infections have a high probability of a relationship with febrile convulsions; therefore, it is necessary to identify the clinical properties of febrile convulsions in relation to domestic influenza virus infections. METHODS: Between November 2005 and February 2008, children hospitalized because of febrile convulsions and subsequently confirmed to have influenza infections were enrolled as subjects (patient group, n=11). The control subjects were those admitted with influenza virus infections but no febrile convulsions (control group 1, n=46) and those who developed febrile convulsions without influenza virus infection (control group 2, n=53). RESULTS: The patient group showed a higher maximum body temperature (39.3+/-0.5degrees C), more histories of past febrile convulsions (72.7%), and a shorter total duration of fever (2.9+/-1.2 days) than control group 1. When multivariate analysis was performed, the probability of febrile convulsions was found to be as high as 225.9 times in patients who had influenza virus infections with a past history of febrile convulsions (OR=225.9, 95% CI: 1.7-4780.0, P<0.05). When patients with febrile convulsions were compared based on the symptoms of influenza virus infections, the patient group showed a shorter duration of fever (0.9+/-0.7 days) before convulsion than control group 2; these convulsions were mostly a recurrence of febrile convulsions. When multivariate analysis was performed, the cases with a past history of febrile convulsions showed 5.5 times (OR=5.5, 95% CI: 1.2-25.1, P=0.03) the probability of convulsions when infected with the influenza virus, and this probabilit. decreased by 0.3 times over one-day increments of the febrile period until febrile convulsions (95% CI: 0.1-0.9, P=0.02). Maximum body temperature, total duration of fever, family history of febrile convulsions, and complex febrile convulsions did not show a statistical significance. CONCLUSION: In cases of pediatric influenza virus infection, the past history of febrile convulsions could be identified within the risk factor of recurrent febrile convulsions. Therefore, influenza vaccination of children having a past history of febrile convulsions will be helpful to avoid the recurrence of these convulsions.

PURPOSE: This study was designed to explore what experiences nurses had while caring and providing emotional support for patients. METHODS: Participants were eight nurses working at hospitals for more than one year. Data were collected from June, 2006 to January, 2007 through in-depth interview by using tape-recordings. Data were analysed with the phenomenological method proposed by Colazzi(1978). RESULTS: From significant statements, 4 clustered themes, 7 themes and 23 sub-themes were extracted from the essential meaning of the emotional experience of hospital nurses. The 4 clustered themes were 'movement of mind', 'affection and service for patients', 'worthwhile and conflict' and 'control oneself'. The 7 themes were 'special feeling', 'rapport formation', 'consideration', 'human interaction', 'value discovery', 'loss of volition', and 'keep to balance'. CONCLUSION: Although nurses had tough experiences for providing care for patients' emotional support, they had also experienced spiritual maturity from its experience. The result of this study would contribute for nurses not only to care for patients who need emotional support but also to develop knowledge in nursing.

PURPOSE: To evaluate mortality and morbidity of very low birth weight infants(VLBW infants) born in the Busan area from 1996 to 2005. METHODS: A total of eight neonatal intensive care units (4 university hospitals and 4 general hospitals) in Busan participated in this study. A total of 1,414 VLBW infants were divided into three groups: period I, 1996 to 2000; period II, 1999 to 2002; period III, 2003 to 2005, based on date of birth. We performed a retrospective review of medical records of VLBWinfants and compared the survival rate, morbidity and mortality over the three periods. RESULT: The number of VLBW infants admitted to 8 NICUs in 1996-2005 was a total of 1,414 (1.3% incidence, mean gestational age 29.1+/-2.7 wk, mean birth weight 1158+/-235 g), including 361 (24.7%) extremely low birth weight infants (ELVW infants) who were less than 1,000 g at birth weight. Overall survival rate of VLBW infants was 66.1%. The survival rate of VLBW infants increased significantly over the three periods (period I:57.6%, period II:67.8%, period III:75.7%, P<0.01). Overall survival rate of ELBW infants was 33.8%, and increased from 26.4% in period I to 44.2% in period III (P<0.01). The incidence of respiratory distress syndrome was 45.1%; patent ductus arteriosus, 16.4%; bronchopulmonary dysplasia, 13.1%; blood culture positive sepsis, 12.7%; necrotizing enterocolitis, 6.6%; severe intracranial hemorrhage, 6.5%; and severe retinopathy of prematurity, 5.9%. The main causes of death were respiratory distress syndrome and sepsis. CONCLUSION: Overall survival rate of very low birth weight infant in Busan area during the last 10 years was 66.1%, and increased significantly over the three periods.

Journal of the Korean Pediatric Cardiology Society 2006;10(3):309-316
PURPOSE: Interleukin 18 (IL-18) is now recognized as an important regulator of innate and acquired immune response. IL-18 is a proinflammatory cytokine which induces IFN-gamma, TNF-alpha, Granulocyte-macrophage Colony-stimulating factor (GM-CSF), IL-1, IL-4 and IL-10, to activate killing by lymphocytes, and to up-regulate the expression of certain chemokine receptors. The authors hypothesized that elevated concentration of IL-18 was related to the pathophysiology of KS. The aims of the present study was to evaluate serial changes of serum IL-18 level in acute and subacute phase of KD, and Comparison of serum IL-18 levels, biochemical profiles and the duration of fever. METHODS: We determined simultaneously the serum concentrations of IL-18 and C-reactive protein (CRP) as well as the white blood cell (WBC) count in 23 patients with acute and subacute phase of KD, 23 with respiratory tract infection (febrile controls) and 10 healthy children (afebrile controls). RESULTS: Acute-phase KD patients showed a significantly higher mean IL-18 value (492.80+/-143.70 pg/mL) than that of subaute-phase KD patients(230.67+/-144.13 pg/mL) and afebrile control (223.97+/-164.12 pg/mL)(p<0.05). Subacute-phase KD patients showed a significantly lower level of IL-18 compared to febrile control(519.77+/-242.05 pg/mL)(P<0.05). The IL-18 values in the acute-phase patients showed a positive correlation with CRP (r=0.413, P=0.030), but there were no other correlations between serum IL-18 value and other profiles. CONCLUSION: The results showed increased IL-18 values in the acute phase and normal values in subacute phase of KD. but IL-18 values were not directly correlated with WBC count, CRP and the duration of fever except between IL-18 value and CRP in the acute phaseof KD. The results suggest that IL-18 pathways were activated in the acute phase of KD, and IL-18 production may not be associated with the severity of inflammation in KD.

Ascaris lumbricoides is the most common intestinal parasite in less-developed countries as well as in areas with poor sanitation. Highly motile mature worms may enter the ampulla of Vater and migrate to the bile or pancreatic ducts causing cholangitis, biliary stones, cholecystitis, pancreatitis and a liver abscess. The incidence of pancreatitis due to biliary ascariasis is relatively common in endemic areas, but only a few cases have been reported in Korea since 1990. A 68-year-old woman was admitted with a sudden onset of epigastric pain. She was diagnosed with acute pancreatits due to ascaris based on computed tomography, the ampulla-impacted state of the worm and an elevated serum amylase level. The patient recovered without complications after the ascaris had been extracted using grasp forceps during endoscopy. The patient also received antihelminthic therapy. We report this case with a review of the relevant literatures.

Dumping syndrome is a known complication of gastric surgery in adults, but a very rare disease in the pediatric population. We report on a case of dumping syndrome in a 19-month-old child, who underwent gastrojejunal feeding tube insertion for the treatment and prevention of gastroesophageal reflux and frequent aspiration pneumonia. At 17 months of age, 2 months after the beginning of gastrojejunal tube feeding, postprandial diaphoresis, palpitation, lethargy, bloating, and diarrhea occurred, and a single episode of convulsion with hypoglycemia were noted. Early and late dumping syndrome was confirmed by an abnormal oral glucose tolerance test with early onset hyperglycemia followed by delayed onset hypoglycemia. Diet therapy including uncooked corn starch then improved the postprandial diaphoresis, abnormal glucose levels, and her nutritional status. We conclude that dumping syndrome may be considered as a complication of gastrojejunal tube feeding in a child.

Korean Journal of Pediatrics 2005;48(9):998-1003
PURPOSE: We evaluated the occurrence of renal scarring in children with unilateral vesicoureteral reflux (VUR), and the relationships between renal scar formation and risk factors such as VUR, duration of fever, acute-phase reactant, age, and sex. METHODS: We retrospectively analyzed the data of 35 children newly diagnosed with unilateral vesicoureteral reflux after urinary tract infection (UTI) in Wallace Memorial Baptist Hospital between January 1996 and December 2004. Ultrasonography, Erythrocyte sedimentation rate (ESR), and C- reactive protein (CRP) were performed initially. Voiding cystourethrography (VCUG) was performed 1 to 3 weeks after treatment with UTI. (99m) Tc-dimercaptosuccinic acid (DMSA) scan was performed 4 to 6 months after treatment. RESULTS: Scintigraphic renal damage was present in 29 percent of the refluxing and in 3 percent of the nonrefluxing kidneys (P< 0.05). The severity of VUR was significantly correlated with renal scar formation (P< 0.05). The duration of fever before treatmen (5.0+/-1.3 vs 2.6+/-1.3) and prolonged fever of over 5 days were significantly different between renal scar group and non-renal scar group (P< 0.05). ESR (56.3+/-23.8 vs 27.9+/-18.1 mm/hr, P< 0.05) and CRP (12.8+/-7.3 vs 3.9+/-3.8 mg/dL, P< 0.05) at the diagnosis of UTI in the renal scar group were higher, compared to those of the non-renal scar group. There were no significant differences in age and sex between the two groups. CONCLUSION: The presence and grade of VUR, the duration of fever before treatment, prolonged fever over 5 days, ESR, and CRP were risk factors for renal scarring, irrespective of age and sex. Diagnosis and management of VUR, in children with UTI, is important to prevent renal scars.

BACKGROUND/AIMS: Although the majority of patients with Mallory-Weiss syndrome (MWS) have a benign course, MWS patients with recurrent bleeding have an unfavorable outcome and require intensive care. Therefore, this study was carried out to identify the risk factors for recurrent bleeding in MWS patients. METHODS: The medical records of patients with MWS between January 1999 and December 2003, were reviewed retrospectively. Demographics, initial clinical and laboratory parameters, and endoscopic findings of the patients with and without recurrent bleeding were compared and the potential risk factors predicting recurrent bleeding in MWS were evaluated. RESULTS: A total of one hundred and fifty-nine patients (22 women, 137 men, mean age 48.1 years old) were enrolled in the study. Recurrent bleeding was observed in 17 patients (10.7%). Those patients with recurrent bleeding showed higher frequency for the presence of shock at initial manifestation, combined liver cirrhosis and endoscopic findings of active bleeding, lower hemoglobin level and platelet count, higher amount of transfusions and epinephrine-mixed fluid injections, and longer hospital stay than those patients without recurrent bleeding. Significant risk factors predicting the recurrent bleeding in MWS were the presence of shock at initial manifestation (OR 3.71, 95% CI 1.07-14.90) and the evidence of active bleeding on endoscopic examination (OR 9.89, 95% CI 1.88-51.98) on multivariate analysis. CONCLUSIONS: Intensive care with close monitoring is required for the patients with shock on initial manifestation or with evidence of active bleeding on endoscopic examinations since these are independent risk factors predicting the recurrent bleeding in MWS patients.
