https://www.selleckchem.com/products/jke-1674.html We describe here an interesting case of a 7-day-old male infant brought with parental concerns of inability to extend both knees. Clinical evaluation revealed dysplastic fingernails, bilateral abnormal patellae, triangular lunules in conjunction with pathognomic iliac horns on pelvic radiographs suggesting the possibility of nail-patella syndrome (NPS). Other competing diagnoses with similar phenotypic features were considered and sequentially excluded. A definitive diagnosis was established by the identification of the principal mutation at the LMX1B gene locus of chromosome 9. NPS is seldom diagnosed in neonates due to the heterogeneity of clinical presentations as well as the subtlety of clinical clues in this population. NPS is a dominantly inherited disorder that is predominantly familial in origin and thus carries important implications for the prenatal diagnosis of future pregnancies as well as pre-emptive surveillance of nephropathy in the index child.Neonatal herpes simplex virus (HSV) infection is rare, with an estimated incidence of 3.58 per 100 000 live births in the UK and should be suspected in any newborn with fever and bacterial culture-negative sepsis. We describe a case of a previously well full-term male neonate who presented with persistent fever and elevated ferritin level that was carried out during the era of the COVID-19 pandemic as part of SARS-CoV-2 panel investigations. Despite the initial negative HSV serology, HSV-1 PCR from a scalp lesion returned positive. He made a full recovery after acyclovir therapy. This case highlights the importance of maintaining a high clinical index of suspicion of HSV infection in any febrile neonate even with absence of maternal history and negative serology, particularly if associated with hyperferritinaemia. We also address the challenge of interpreting inflammatory biomarkers' results for SARS-CoV-2 infection in neonates.A 29-year-old male patient presen
