Hyperhidrosis: the neglected sign in heart failure patients.

Profuse sweating is a symptom often reported by cardiological patients and could be also an early phenomenon of adaptation or rather cardiac maladaptation in the context of incipient heart failure (HF). By definition, in HF patients the low cardiac output causing reduced renal blood supply and reduced pressure in the arterial baroreceptors activate compensatory mechanisms such as the RAAS and the adrenergic autonomic nervous system. The retention of fluids caused by the decompensation of heart-kidney system could generate a reactive hyperhidrosis and even anticipate an incipient decompensation and might prevent manifest volume overload.

External circular fixation: a comparison of infection rates between wires and conical half-pins with threads outside or inside the skin.

Background: The purpose of this study was to evaluate if there is a difference in the rates of infection between Ilizarov wires and half-pins and between half-pins with threads outside and inside the skin in circular fixators modified by Catagni and Cattaneo.

Methods: Between May and December 2004, 218 patients with circular Ilizarov fixators for various orthopaedic indications who visited our Ilizarov clinic were subjected to a one-time evaluation of half-pins and wires.

Results: A total of 1,093 half-pins were checked and 34 (3.
