ABSTRACT
ABSTRACT: Asthma is a major chronic disease affecting children, and children with difficult-to-treat asthma account for a disproportionate share of resource utilisation and healthcare costs. This review presents a comprehensive and up-to-date overview of the treatment strategies in difficult-to-treat paediatric asthma. Mimickers of asthma must first be ruled out, and the diagnosis confirmed with objective tests whenever possible. The effect of comorbid conditions such as obesity, smoking, other atopic conditions and psychosocial factors on asthma control and severity should be considered. Treatment can then be optimised by implementing personalised strategies, including the use of appropriate drug delivery devices and adherence monitoring. Biologics can be an alternative treatment option for selected patients but should not be a substitute for addressing poor adherence. Many patients with difficult-to-treat asthma may not have severe asthma, and the physician should work with patients and families to achieve good asthma control via an individualised approach.
ABSTRACT
The skin manifestations of Langerhans cell histiocytosis (LCH) in the neonate have a heterogenous presentation and can mimic other causes of neonatal rashes. We report an uncommon case of LCH in a term female neonate presenting with non-specific papules and vesicles from the first day of life. There was a maternal history of genital herpes simplex virus (HSV) infection in the third trimester. Blood, cerebrospinal fluid, surface swabs and vesicular fluid were negative for HSV by PCR, and a skin biopsy confirmed the diagnosis of LCH. Further investigations for systemic involvement returned negative. Our case emphasises the variable and non-specific presentation of neonatal cutaneous LCH, which can progress to or be part of multisystem disease.

AIM: This retrospective chart review aimed to identify factors in childhood bacterial meningitis that predicted disease severity and long-term outcome. METHODS: The study included 112 episodes of microbiologically confirmed bacterial meningitis in children aged three days to 15 years who were admitted to a Singapore hospital from 1998 to 2013. RESULTS: The mortality rate was 6%, and 44% required intensive care unit (ICU) admission. Predictive factors associated with ICU admission included pneumococcal meningitis, with an odds ratio (OR) of 5.2 and 95% confidence interval (CI) of 1.5-18.2, leukopenia (OR 5.6, 95% CI 1.7-17.9) and a cerebrospinal fluid (CSF):serum glucose ratio <0.25 (OR 4.5, 95% CI 1.4-14.4). An initial CSF white blood cell count >1000/mm(3) (OR 0.26, 95% CI 0.086-0.76) was negatively associated with ICU admission. Five years after meningitis, 32% had residual sequelae, and the associated prognostic factors were Haemophilus influenzae type b (Hib) meningitis (OR 29.5, 95% CI 2-429), seizures during their inpatient stay (OR 10.6, 95% CI 1.9-60.2) and septic shock (OR 8.4, 95% CI 1.1-62.1). CONCLUSION: As mortality was low in this bacterial meningitis study, ICU admission was used as a marker of disease severity. These findings underscore the importance of the pneumococcal and Hib meningitis vaccines.

Acute amiodarone toxicity after a single dose of intravenous amiodarone is very rarely seen. We report the case of a 64-year-old Chinese man who presented with atrial fibrillation and fluid overload due to congestive cardiac failure. He was treated with a single bolus dose of intravenous amiodarone, after which he developed elevated serum transaminases, coagulopathy, thrombocytopenia and acute renal failure. His parameters returned to normal after 25 days and his recovery was uneventful.
