To determine the maximal response of the temperature and inflammatory response to SARS-CoV-2 infection and how these are modified by age. ⋯ Age modifies both maximal temperature and systemic inflammatory response in patients with SARS-CoV-2 infection.

New thrombocytopenia may be associated with a variety of conditions and diagnosis can be challenging. Presentation can vary from life-threatening bleeding or thrombosis to an incidental finding in an asymptomatic patient. New thrombocytopenia requires urgent investigation. ⋯ Aside from the actively bleeding patient, rare but life-threatening causes of thrombocytopenia must be identified early as they require urgent treatment. These include thrombotic thrombocytopenic purpura, disseminated intravascular coagulation, suspicion of new acute promyelocytic leukaemia, and vaccine-induced prothrombotic immune thrombocytopenia. Here, we discuss how to approach a patient with new thrombocytopenia, along with key differentials not to be missed.

Observational Study
Feasibility and accuracy of the 40-steps desaturation test to determine outcomes in a cohort of patients presenting to hospital with and without COVID-19.
Desaturation on exercise has been suggested as a predictive feature for deterioration in COVID-19. The objective of this paper was to determine the feasibility and validity for the 40-steps desaturation test. A prospective observational cohort study was undertaken in patients assessed in hospital prior to discharge. ⋯ Of 13 patients who had a desaturation of 3% or more during exercise, none was readmitted to hospital within 30 days. Not enough patients with COVID-19 could be recruited to the study to provide evidence for the safety of the test in this patient group. The 40-steps desaturation test requires further evaluation to assess clinical utility.

A 76-year-old man presented to the hospital with intermittent dizziness, memory impairment and jerky movements. Evaluation revealed them to be faciobrachial dystonic seizures and antibodies to voltage-gated potassium channel complexes were found. He was treated with intravenous methylprednisolone and rituximab, and made a remarkable recovery. Magnetic resonance imaging of the brain was normal, although positron emission tomography - computed tomography showed striking basal ganglia changes.

Multiple myeloma (MM) is a type of haematological bone marrow malignancy. Cancer Research UK reports that MM is the 18th most common cancer in the UK, accounting for 2% of all new cancer cases, yet, non-haematologists often lack familiarity with the pathology and initial investigations. This paper aims to demonstrate the diagnostic features, relevant investigations and basic management plan for the non-specialist.
