Unusual spinal needle defect: projecting stylet

Exchange of intravenous cannula over stylet of spinal needle: our experience and comments.

I read the recent article by Garg,(1) in which the author described the use of a spinal needle stylet to replace a faulty intravenous cannula. The technique is useful; however, there are some concerns. We have tried the stylet of a 26-G spinal needle for the exchange of a 24-G cannula in ten paediatric patients and have the following observations to make. The exchange was successful in only one...

Unusual Spinal Dysraphic Lesions

Human tail and multiple spinal dysraphism are unusual congenital malformations. Human tail appeared as a prominent lesion from the lumbosacrococcygeal region, generally without connection between the tail and the neurospinal axis. Spinal dysraphisms are usually isolated, reaching 0.038% of incidence of multiple spinal dysraphisms in the same child. There were three cases described of unusual sp...

Leptin Activates Hypothalamic CART Neurons Projecting to the Spinal Cord

The adipocyte-derived hormone leptin decreases body weight in part by activating the sympathetic nervous system, resulting in increased thermogenesis and energy expenditure. We investigated hypothalamic pathways underlying leptin's effects on stimulating the sympathetic nervous system. We found that leptin activates neurons in the retrochiasmatic area (RCA) and lateral arcuate nucleus (Arc) tha...
