Significantly more children with ALRI who needed supplementary oxygen and ventilator management were vitamin D deficient. These findings suggest that the immunomodulatory properties of vitamin D may influence the severity of ALRI.
Based on the definition of obesity, POW is the better index of body fatness to assess its individual change for boys during early pubertal period, because the index independent from the change in LBM is supposed to be the appropriate index for obesity in practical use.
PurposeThe aim was to investigate the characteristics of abdominal fat distribution in Japanese adolescents with type 2 diabetes mellitus.Patients and methodsEighty-six Japanese adolescents with simple obesity or type 2 diabetes mellitus treated between 2002 and 2018 were included. The subjects were classified into the simple obesity group (SO group, n=38) and type 2 diabetes mellitus group (DM group, n=23) by matching average age and gender ratio. The metabolic parameters VFA, SFA, and V/S ratio were compared between the 2 groups. Multivariate logistic regression analysis was performed to identify clinical factors associated with type 2 diabetes mellitus. Linear regression analysis was performed between hemoglobin A1c (HbA1c) and visceral fat area (VFA), subcutaneous fat area (SFA), or VFA-to-SFA ratio (V/S ratio) among all enrolled subjects. Finally, correlation analyses were performed to determine the relationships between VFA, SFA, and V/S ratio and metabolic parameters of the DM group. For the metabolic parameters, serum lipids, alanine aminotransferase (ALT), and HbA1c were measured without fasting. The VFA and SFA at umbilical level were investigated using computed tomography.ResultsVFA and V/S ratio in DM group were higher than those in SO group (p=0.04 and p<0.01, respectively). SFA in DM group was lower than that in SO group (p<0.01). VFA and SFA, and non-high density lipoprotein (HDL) cholesterol were identified as being independently associated with type 2 diabetes mellitus (odds ratio, 1.05, 0.98, and 1.04, respectively, p<0.05). HbA1c was correlated with VFA and V/S ratio (p<0.01). In DM group, VFA and SFA were positively correlated with systolic blood pressure (p<0.01), ALT (p<0.05), total cholesterol (p<0.05), and non-HDL cholesterol (p<0.01); however, V/S ratio was not correlated.ConclusionAbdominal fat distribution in Japanese adolescents with type 2 diabetes mellitus was different from those with simple obesity and might associate with glucose and lipid metabolism.
We report a 7-year-old girl with Henoch-Schönlein purpura who developed hypertensive encephalopathy. She showed a sudden onset of neurological symptoms, including hypertension, convulsions, disturbance of consciousness, and cortical blindness. Reversible posterior leukoencephalopathy syndrome was diagnosed from the findings on magnetic resonance imaging. Reports of this syndrome in patients with Henoch-Schönlein purpura are very rare. However, if symptoms suggest central nervous system involvement, neuroimaging should be done for rapid diagnosis, and immediate treatment should be provided to avoid sequelae.
BackgroundDalteparin, a low-molecular-weight heparin, has anticoagulant and anti-angiogenic activity. This study investigated whether dalteparin reduced coronary artery lesion (CAL) prevalence, and resistance to intravenous immunoglobulin (IVIG) therapy in Kawasaki disease (KD).MethodsThis retrospective study comprised two parts. In the first cohort, 126 patients with KD (68 male, 58 female; median age: 22 months, range: 1–67 months) admitted to Nihon University Nerima-Hikarigaoka Hospital from January 2004 to June 2008, received either dalteparin 75 IU/kg/day, IVIG 400 mg/kg/day for 5 consecutive days, and aspirin 30 mg/kg/day, or dalteparin 75 IU/kg/day and aspirin 30 mg/kg/day, until clinical improvement. Control data came from the 2005–6 Nationwide KD survey. In the second cohort, 112 patients with KD (59 male, 53 female; median age: 19 months, range: 1–66 months) admitted from June 2010 to February 2012, received either dalteparin 75 IU/kg/day, IVIG 2.0 g/kg over 12 h, and aspirin 30 mg/kg/day, or dalteparin 75 IU/kg/day and aspirin 30 mg/kg/day. Control data came from the 2009–10 Nationwide KD survey. No patients enrolled in the nationwide surveys received dalteparin. All patients at our institution were given dalteparin in their combination therapy.ResultsA comparison of the first cohort with controls in the nationwide survey showed that the prevalence of initial administration of IVIG was 80.2% versus 86.0%; the rate of additional IVIG administration was 7.1% versus 14.0% (p = 0.03); CAL prevalence in the acute period was 4.8% versus 11.9% (p < 0.01); and the prevalence of cardiovascular sequelae was 0% versus 3.8% (p < 0.05). A comparison of the second cohort with controls in the nationwide survey showed that the rate of initial administration of IVIG was 92.9% versus 89.5%; the rate of additional IVIG administration was 8.9% versus 17.1% (p = 0.02); the prevalence of resistance to IVIG was 3.6% versus 14.9% (p < 0.001); and CAL prevalence in the acute period was 2.7% versus 8.6% (p = 0.03).ConclusionsThis study found that adjunctive dalteparin was associated with a lower prevalence of IVIG resistance and CAL in young children with KD.Trial registrationUMIN-CTR: UMIN000010349.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
