https://www.selleckchem.com/products/NPI-2358.html A 16-year-old male with Becker muscular dystrophy was admitted to hospital with a significant liver injury due to paracetamol. The dosage of paracetamol ingested was within current guidance yet there was sudden derangement of liver function. The patient was treated with five days of N-acetyl cysteine to which he responded, with his alanine aminotransferase improving from 5,599 to 652 and international normalised ratio from 5.0 to 0.9. He had risk factors for paracetamol toxicity as he was malnourished and had muscular dystrophy. The purpose of this case report is to highlight that despite prescribing approved dosages of paracetamol some patients may have toxicity due to altered body composition and pharmacokinetics.Diphtheria is a vaccination preventable infectious disease with local and systemic complications predominantly affecting upper respiratory tract in younger ( less then 5-year age) children. Its virulence is due to its ability to produce toxin which can cause fatal complications such as myocarditis and permanent damage in form of peripheral neuropathy. Diagnosis of diphtheria is primarily clinical supported by demonstration of toxin producing bacteria by culture. Early diagnosis and management with diphtheria anti-toxin can prevent mortality and morbidity. Here we present a case of 16-year-old boy managed with azithromycin, amoxycillin-clavulanic acid and diphtheria anti-toxin with complete recovery.This case brings out the importance of recognising the re-emergence of diphtheria in older age groups. Lacunae in the universal immunisation process, rumours on vaccination effects and poor living conditions for refugee population are likely reasons in Asia and Europe. Universal immunisation, early diagnosis, prophylaxis and adequate supportive care are measures to prevent it.A thorough understanding of the pros and cons of the various study designs is critical to correct interpretation of their results.
