Langerhans cell histiocytosis (LCH) in adults is rare and regarded as an ‘orphan disease.’ The systemic symptoms of LCH can mimic many other undifferentiated diseases seen at the primary care level. Failure to diagnose and delays in referral are common pitfalls in the management of this disease. We present a case of a 34-year-old woman with referred knee pain who was eventually diagnosed with multi-system LCH 4 years after the initial presentation. The mean age of presentation of LCH symptoms in adults is 33. Bone lesions are the frequent presentation of LCH in this age group. Endocrine involvement in LCH is seen in the form of diabetes insipidus (DI), which remains the most common extraskeletal presentation of LCH in adults. In the case discussed here, a definitive diagnosis of LCH was established through tissue biopsy. The spectrum of undifferentiated symptoms underscores the difficulty and delay in making a diagnosis associated with the condition. Most GPs not only face the predicament of initial recognition but also fail to merge presenting symptoms to form a purposeful referral of this elusive disease to a tertiary care unit.

This study examined the impact of universal screening in diagnosing and managing gestational diabetes (GDM) amongst antenatal mother and associated neonatal outcomes. It is a single-centre, retrospective study on routinely collected data of antenatal women in Health Clinic Seremban over one year in 2018. All women diagnosed with GDM, who were not known sufferers of type 1 or type 2 diabetes were included in this study. Participants were stratified according to risk factors for GDM to compare the performance of a selective high-risk screening approach to that of universal screening for detecting GDM. Subjects were categorized as high-risk for GDM based on the guidelines recommended by the Malaysian Clinical Practice guidelines. It was found that through universal screening, 246 antenatal mothers were tested positive for GDM out of the 987 of these mothers without prior diabetes, giving a prevalence of 24.9%. If selective screening using traditional risk factors had been employed, 54 (22%) of the antenatal mothers diagnosed with GDM would have been missed. It was established that risk factors for GDM included advancing age, other ethnicities (patients that are not of Malay, Chinese nor Indian ethnicities), obesity, history of abortion or GDM and family history of diabetes mellitus. Neonatal outcomes of those with GDM as compared to those without were similar. This study highlights that universal screening improved GDM detection rates amongst antenatal mothers. The increased detection helped facilitate an earlier intervention which may have contributed to better antenatal management and outcomes for neonates and their mothers.
