Pituitary dysfunction and association with fatigue in stroke and other acute brain injury.

BACKGROUND: Poststroke fatigue (PSF) is a highly prevalent and debilitating condition. However, the etiology remains incompletely understood. Literature suggests the co-prevalence of pituitary dysfunction (PD) with stroke, and the question raises whether this could be a contributing factor to the development of PSF. This study reviews the prevalence of PD after stroke and other acquired brain injuries and its association with fatigue. SUMMARY: We performed a bibliographic literature search of MEDLINE and EMBASE databases for English language studies on PD in adult patients with stroke, traumatic brain injury (TBI) or aneurysmatic subarachnoid hemorrhage (aSAH). Forty-two articles were selected for review. Up to 82% of patients were found to have any degree of PD after stroke. Growth hormone deficiency was most commonly found. In aSAH and TBI, prevalences up to 49.3% were reported. However, data differed widely between studies, mostly due to methodological differences including the diagnostic methods used to define PD and the focus on the acute or chronic phase. Data on PD and outcome after stroke, aSAH and TBI are conflicting. No studies were found investigating the association between PD and PSF. Data on the association between PD and fatigue after aSAH and TBI were scarce and conflicting, and fatigue is rarely been investigated as a primary end point. KEY MESSAGES: Data according to the prevalence of PD after stroke and other acquired brain injury suggest a high prevalence of PD after these conditions. However, the clinical relevance and especially the association with fatigue need to be established.

[The practice guideline 'Urinary-tract infections' (second revision) from the Dutch College of General Practitioners; a response from the perspective of urology]. / De standaard 'Urineweginfecties' (tweede herziening) van het Nederlands Huisartsen Genootschap; reactie vanuit de urologie.

The convenient and clearly organised structure of this second revision of the practice guideline on urinary-tract infections from the Dutch College of General Practitioners provides a clearly described role for the general practitioner in the diagnosis and treatment of such infections. Most striking is the change in the classification of diagnostic patient categories. It seems that pregnant women with urinary-tract infections represent an important group in extramural medicine. This revised guideline shows great promise for ensuring efficient and effective routing of the various patient groups presenting with urinary-tract infections at the office of the general practitioner.
