Predicting relapsed/refractory disease in childhood hemophagocytic lymphohistiocytosis based on clinical features at diagnosis: A 13-year single-institute retrospective study in Thailand.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease. Relapsed/refractory disease is the main cause of death. This study aims to determine the prognostic indicators for relapsed/refractory disease in childhood HLH (R/R HLH).

Timing of Childhood-Onset Systemic Lupus Erythematosus Diagnosis Relative to Menarche and the Impact on Final Adult Height.

Objective: The aim of this study was to examine the impact of timing of a childhood-onset systemic lupus erythematosus (SLE) diagnosis relative to menarchal status, on final height, accounting for disease-associated factors.

Methods: We conducted a cohort study of female patients age <18 years at childhood-onset SLE diagnosis, followed at a tertiary care pediatric center from July 1982 to March 2016 and restricted to patients with documented age of menarche and final height. We compared final height between patients diagnosed pre- and postmenarche.

Hallmark trials in ANCA-associated vasculitis (AAV) for the pediatric rheumatologist.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) refers to a complex group of systemic vasculitides that are characterized by primary small-to-medium sized blood vessel inflammation with the presence of autoantibodies known as ANCA. AAV diseases include Granulomatosis with Polyangiitis (GPA), Eosinophilic Granulomatosis with Polyangiitis (EGPA), and Microscopic Polyangiitis (MPA). AAVs are challenging conditions associated with high cumulative disease and treatment related morbidity and mortality.

The correlation between the Childhood Health Assessment Questionnaire and disease activity in juvenile idiopathic arthritis.

Background: The Childhood Health Assessment Questionnaire (CHAQ) has been adapted from the Stanford Health Assessment Questionnaire for assessing functional ability in children. The present study aimed to determine the correlation between CHAQ and disease activity in juvenile idiopathic arthritis (JIA) during active and inactive disease.

Methods: JIA patients in the Pediatric Department, Ramathibodi Hospital, between January 2011 and December 2013, were included in the study.

Subtle inflammation: a possible mechanism of future cardiovascular risk in obese children.

Purpose: The risk of cardiovascular disease (CVD) has been shown to be associated with systemic inflammation in obese adults with metabolic syndrome (MetS). The aims of this study were to evaluate the prevalence of MetS and its relation to inflammatory markers in obese Thai children.

Methods: A cross-sectional study was conducted.

Neurological Involvement and Hepatocellular Injury Caused by a Snake With Hematotoxin Envenomation.

Venomous snakes with hematotoxin-Russell's viper (Daboia spp), Malayan pit viper (Calloselasma rhodostoma), and green pit viper (Cryptelytrops albolabris and C macrops, previously named Trimeresurus spp) are commonly found in Thailand. Coagulation factor activation, thrombocytopenia, hyperfibrinolysis, and disseminated intravascular coagulation are the main mechanisms of hemorrhaging from these snake bites. The neurological involvement and hepatocellular injury after Russell's viper bites were reported in Sri Lanka, but there is no report from Southeast Asia.
