Case Reports
Lessons of the month: A challenging presentation of hypopituitarism secondary to an intracerebral aneurysm.
A 65-year-old man presented to ambulatory care with a 10-month history of muscle weakness, weight loss, dysphagia and fatigue. Prior to presentation he had been managed in general practice for hypothyroidism with a low T4 level and normal thyroid stimulation hormone (TSH). He was commenced on levothyroxine yet, despite dose titrations, had ongoing symptoms. ⋯ This case highlights the importance of correctly interpreting TFTs as this patient's initial TFTs indicated central hypothyroidism which should have prompted urgent pituitary hormone screening. The risk of addisonian crisis with commencement of levothyroxine without steroid replacement in secondary hypothyroidism emphasises the importance of TFT interpretation. Internal carotid artery aneurysms are a rare, yet important, cause of hypopituitarism resulting in high mortality and morbidity associated with delayed diagnosis secondary to the pressure effects of the aneurysm or the effects of aneurysmal rupture.

Contact tracing is central to the public health response to COVID-19, but the approach taken has received criticism for failing to make enough of an impact on disease transmission. We discuss what can be learned from contact tracing in other infections, and how the natural history of COVID-19 should shape the strategies used.

Ulcerative colitis is a relapsing and remitting disease that is increasing in incidence and prevalence. Management aims to achieve rapid resolution of symptoms, mucosal healing and improvement in a patient's quality of life. 5-aminosalicylate acid medications remain the first-line treatment for mild to moderate disease. ⋯ Importantly, despite best medical therapy, surgery may be required in a proportion of patients. The future will likely see an array of new therapeutic options for those with ulcerative colitis with the potential for a more personalised treatment approach.

Neurological manifestations associated with SARS-CoV-2 infection as well as its pathogenesis are insufficiently explained. We present two cases of severe COVID-19 who required hospitalisation in the intensive care unit with persistently depressed mental status and severe leukoencephalopathy. We discuss the clinical and radiological findings and also propose the possible pathogenesis involved.

Loperamide is an over-the-counter medication which is commonly used to treat diarrhoea. In excessive doses, loperamide acts as an opioid on the central nervous system, which contributes to its increasing popularity as an alternative substance for opiate addictions. High doses for prolonged periods can cause prolonged QTc and provoke life-threatening arrhythmias, such as ventricular fibrillation. ⋯ Following syncopal episodes at rest, she was admitted for a period of monitored observation and later discharged with a plan to taper her loperamide in the community. Upon second presentation, her loperamide was replaced with buprenorphine patches, which were then weaned successfully in the community. Despite this, she passed away several months later, most likely from an underlying congenital cardiac arrhythmia which was unmasked by excessive use of loperamide.
