Phaeochromocytoma and paraganglioma.

Phaeochromocytomas and paragangliomas are rare catecholamine-producing neuroendocrine tumours which can potentially cause catastrophic crises with high morbidity and mortality. This best practice article considers the causes and presentation of such tumours, screening and diagnostic tests, management of these patients and consideration of family members at risk.

Haematological and biochemical pathology markers for a predictive model for ITU admission and death from COVID-19: A retrospective study.

Coronavirus disease (COVID-19) caused by SARS-CoV-2 has affected over 227 countries. Changes in haematological and biochemical characteristics in patients with COVID-19 are emerging as important features of the disease. This study aims to identify the pathological findings of COVID-19 patients at Bedford Hospital by analysing laboratory parameters that were identified as significant potential markers of COVID-19.

Adrenal insufficiency.

Adrenal insufficiency (AI), first described by Thomas Addison in 1855, is characterised by inadequate hormonal production by the adrenal gland, which could either be primary, due to destruction of the adrenal cortex, or secondary/tertiary, due to lack of adrenocorticotropic hormone or its stimulation by corticotropin-releasing hormone. This was an invariably fatal condition in Addison's days with most patients dying within a few years of diagnosis. However, discovery of cortisone in the 1940s not only improved the life expectancy of these patients but also had a dramatic effect on their overall quality of life.

A UK national audit of the laboratory investigation of phaeochromocytoma and paraganglioma.

Background: Phaeochromocytomas and paragangliomas (PPGL) are catecholamine secreting tumours associated with significant morbidity and mortality. Timely diagnosis and management are essential. A range of laboratory tests can be utilised in the investigation of PPGL.
