Case report: Managing multisystem inflammatory syndrome in children (MIS-C) in Lao People's Democratic Republic, a success story.

Introduction: Multisystem inflammatory syndrome in children (MIS-C) is believed to be one of the most important life-threatening complications of COVID-19 infection among children. In any setting, early recognition, investigations, and management of MIS-C is crucial, but it is particularly difficult in resource-limited settings (RLS). This is the first case report of MIS-C in Lao People's Democratic Republic (Lao PDR) that was promptly recognized, treated, and resulted in full recovery with no known complications despite the resource limitations.

Establishing a case definition of thiamine responsive disorders among infants and young children in Lao PDR: protocol for a prospective cohort study.

Introduction: Diagnosis of infantile thiamine deficiency disorders (TDD) is challenging due to the non-specific, highly variable clinical presentation, often leading to misdiagnosis. Our primary objective is to develop a case definition for thiamine responsive disorders (TRD) to determine among hospitalised infants and young children, which clinical features and risk factors identify those who respond positively to thiamine administration.

Methods And Analysis: This prospective study will enrol 662 children (aged 21 days to <18 months) seeking treatment for TDD symptoms.
