Patients with chronic schizophrenia and psychosis are prone to develop hyponatremia secondary to psychogenic polydipsia.

Benign Ethnic Neutropenia (BEN) is a common form of neutropenia defined as an absolute blood neutrophil count (ANC) of < 1.5 x 109/l, usually observed in Afro-Caribbeans. These patients are not at increased risk of infection despite their neutropenia, unless they are on medications which can cause neutropenia. Amongst these drugs antithyroid medications are known to cause agranulocytosis defined as ANC of <500/μl. We report a case of 24 years old male w...

There is limited research into the impact of active brown adipose tissue (aBAT) in patients with phaeochromocytomas and paragangliomas (PPGLs).

Furthermore, it has been suggested that aBAT may be linked to increased mortality. Systematic searches of the Medical Literature Analysis an...
