It has a predilection for trunk and proximal extremities where it presents as poorly circumscribed overgrowth of fatty tissue. Definite diagnosis is established by histological examination of tumor.

Patterns of coverage of psychiatric emergencies

A massive change in the detection of psychiatric cases in the emergency room was recorded when pattern of coverage was changed from "on-call" basis to "continuous physical presence" of psychiatry residents in the emergency room.     

Prostaglandin E1-induced Catalepsy in the Rat: Role of Putative Neutrotransmitters

Prostaglandin E₁ (PGE₁) produced dose-related catalepsy in rats when administered intracerebroventricularly. PGE₁ induced catalepsy was significantly inhibited after pretreatment with pharmacological agents known to attenuate central serotonergic and cholinergic activity. It was also inhibited by PGF₂ and naloxone. On the contrary, treatments enhancing central dopaminergic activity also reduced the cataleptic effect of PGE₁. The results suggest that PGE₁ induces catalepsy in rats by modulating activity of central neurotransmitters.
