The migration of catheter in the central venous system is a rare but serious iatrogenic complication. At short term this life threatening complication induces arythmias and then infectious, thrombotic and mechanical complications. Simple interventional procedures, rapidly achieved can prevent these complications.

This study describes the structures of the three meningeal envelopes surrounding the spinal cord and delineating the perispinal spaces. The pia mater is a membrane constituted of a deep and a superficial layer. This structural organization explains the relationship of the piamater with the spinal vessels and the cerebrospinal fluid. ⋯ The problem of the cerebrospinal fluid physiology is then discussed. After remaining the secretion and circulation of the cerebro spinal fluid, the problem of its spinal resorption is discussed. This resorption can be done by ascending pathways either lymphatics or veins.

Clinical Trial
[Evaluation of the role of echography in the positive diagnosis of renal colic secondary to kidney stone].
To evaluate sensitivity and specificity of ultrasound in detecting urinary calculus in renal colic, a prospective study of 31 patients examined by both ultrasound and intravenous urography (IVU) was undertaken. Of the 27 cases of renal colic proved by IVU and/or recovery of a calculus, ultrasound correctly diagnosed urinary calculus in 26 cases with a sensitivity of 96.3%. ⋯ Specificity of ultrasound was 100%. The results of this study support the use of ultrasound in detecting renal calculus and point out the important place of ultrasound in initial evaluation of renal colic.

Case Reports
[Portal venous gas and necrotizing enterocolitis. Apropos of a case diagnosed by x-ray computed tomography].
Hepatic portal vein gas is defined as the presence of gas in the portal system. Its presence is exceptional in adults and indicates severe disease. ⋯ We report the case of a patient with acute abdominal pain associated with vascular and neurological symptoms; abdominal C. T. scan revealed hepatic portal vein gas and supported the diagnosis of necrotizing enterocolitis.
