Clinical TrialSonographic diagnosis of cisternal subarachnoid hemorrhage in the premature infant.
To evaluate sonographic criteria for the diagnosis of subarachnoid, and particularly cisternal, hemorrhage in the preterm infant. ⋯ A highly specific, although somewhat insensitive, sonographic diagnosis of subarachnoid hemorrhage can be made from the appearance of the subarachnoid cisterns. The diagnosis of subarachnoid hemorrhage may predate the ultrasound diagnosis of intraventricular hemorrhage and may alert the neonatologist to the need for follow-up sonograms in the absence of ultrasound evidence of intraventricular hemorrhage.

To describe the clinical features of cardiac injury associated with neurogenic pulmonary edema (NPE) in patients with acute subarachnoid hemorrhage (SAH). ⋯ A reversible form of cardiac injury may occur in patients with NPE following SAH and is associated with characteristic clinical findings. Impaired LV hemodynamic performance in this setting may contribute to cardiovascular instability, pulmonary edema formation, and complications from cerebral ischemia.

Case Reports
Cardiac arrhythmia associated with reversible damage to insula in a patients with subarachnoid hemorrhage.
The insular cortex has been shown experimentally to contain an arrhythmogenic center that may play an important role in the genesis of cardiac arrhythmias and electrocardiographic changes in patients with intracranial (eg, cerebrovascular) lesions. The description of our case is intended to substantiate this claim with a clinical observation. ⋯ The observed association of a neurosurgical intervention in the region of the left insular cortex with a cardiac arrhythmia supports but does not prove the suggested role of the insulin in the causation of heart rhythm disturbances after stroke.

Case Reports
Subarachnoid hemorrhage: atypical presentation associated with rapidly changing cardiac arrhythmias.
Subarachnoid hemorrhage (SAH) typically presents with sudden onset of severe headache and is often associated with cardiac arrhythmias. The case of a patient with SAH in whom typical presenting signs and symptoms were absent is presented. This case was characterized by rapidly changing arrhythmias observed in the prehospital setting. The diversity and rapid evolution of arrhythmias can be attributed to the autonomic and electrolyte imbalances that often accompany SAH.

Comparative Study
[Elevation of total urinary catecholamines in patients with subarachnoid hemorrhage].
We designed a prospective study in order to evaluate total urinary catecholamines in patients with subarachnoid hemorrhage (SAH) and correlate them with some prognostic factors and its complications. We studied 24 patients: 19 were normotensive, five had had a previous arterial hypertension that persisted during the SAH, and five developed the hypertension during the SAH. The latter showed cardiac complications with a more severely affected Hunt and Hess scale and a higher level of excretion of urinary catecholamines than the normotensive patients (p < 0.003). The cases with previous arterial hypertension that persisted during the SAH had more complications than the normotensive patients but in a lesser degree compared to chose who developed the hypertension during the SAH.
