Gender-related voice problems in transsexuals - therapeutical demands.

The paper presents a case study of a transsexual patient who underwent a voice pitch elevation surgery performed in Poland for the first time. The human voice is a reflection of the working of hormones and human psyche. This fact is of particular importance in transsexualism, a disorder consisting in incongruence between the individual's biological sex and their identified gender.

Densitometric and quantitative ultrasound measurements and laboratory investigations in wheelchair-bound patients.

Skeletal status and laboratory investigations may be influenced by immobilization. Thirty-six wheelchair-bound subjects and 19 age-matched controls were evaluated using measurements of bone mineral density (BMD) at the calcaneus and forearm (PIXI, Madison, WI), amplitude-dependent speed of sound at the hand phalanges (quantitative ultrasound-DBM Sonic 1200, IGEA, Modena, Italy), carboxyterminal telopeptide of type I collagen and bone alkaline phosphatase. In the whole group and in the males, bone mineral density values were significantly lower in comparison with controls (calcaneus, forearm) and in females only for calcaneus.
