Neopterin concentrations, reflecting T-cell macrophage activation, were analyzed in serum and cerebrospinal fluid (CSF) obtained from 14 patients with subarachnoid hemorrhage (SAH). Neopterin concentrations were elevated in both the serum and CSF. The increase in neopterin concentrations was most marked in the CSF, rising from Days 1 to 3 through Days 6 to 9; levels were highest in patient suffering from delayed cerebral ischemia. The present data were interpreted as signs of an ongoing T cell activation both systemically and in the CSF compartment following SAH.

[Usefulness of computerized tomography in the prognosis of subarachnoid hemorrhage].
The authors reviewed the computed tomographic (CT) scans of 129 patients with subarachnoid hemorrhage (SAH). The close correlation is stressed between the severity of the symptoms onset and the amount of blood demonstrated on CT scans. ⋯ CT also shows the possible complications (hematoma, hydrocephalus, mass effect) that, when present, have a negative impact on prognosis, independent of the neurologic condition. Finally, the authors point out how a reliable prognosis of SAH is based upon combined clinical evaluation and CT study.

Review Case Reports
[Neurogenic pulmonary edema, complication of meningeal hemorrhage: report of 4 cases].
Neurogenic pulmonary edema (NPE) observed in 4 patients admitted in Neurosurgical Intensive Care au SAH by ruptured a vascular malformation. This complication is unusual (1.9%) and has been observed in comatose patients. For 3 patients, NEP resorption was rapid, from 12 to 72 hours with a treatment by CCPV with a P. ⋯ The drug must be discussed according to eventual deleterous side effects on cardiac output and systemic resistances. The early hemodynamical study argues for an essentially hemodynamical mechanism due to the brutal symphatic discharge created by cerebral lesions and increasing. ICP, more than a toxic lesionnal edema, as the Weidner's study shows it in ultrastructural analysis of sheep lungs.

Hypovolemia seems a commun state in patients with subarachnoid hemorrhage. It has been further suggested that hypovolemia could cause ischemia if vasospasm is present. Total blood volume and red blood cells volume determined in 84 consecutive patients volume of distribution (of 51Chromium labeled autologous red cells, shows an hypovolemia in 70% of these patients). Associated hypomotremia requires Na restitution with normovolemic hemodilution to facilitate cerebral blood flow.

Case Reports
[A rare and severe complication of meningeal hemorrhage: spinal arachnoiditis with paraplegia].
This observation relates a case of spinal arachnoiditis with paraplegia, for a 56 year old patient hospitalized for a S. A. H. by a ruptured aneurysm of the P. ⋯ A. This patient present some complications, requiring a prolonged ventilatory support with a tracheostomy, a ventricular shunt for hydrocephalus. The treatment is only surgical, and the corticosteroids delay the evolution, but without successful outcome.
