Case Reports[Partial non convulsive epileptic status as initial presentation of limbic encephalitis].
Limbic encephalitis is an unusual presentation of paraneoplastic syndrome, which includes among its symptoms seizures. ⋯ Status epilepticus could be an early sign of limbic encephalitis. The absence of anti-Hu antibodies does not rule out the presence of an underlying small cell lung carcinoma in patients with a clinical diagnosis of limbic encephalitis. Greater awareness for diagnosis and early treatment of the primary tumor offers the best chance for improvement in patients with lung cancer presenting with limbic encephalitis.

Case Reports[Electrocardiographic abnormalities in subarachnoid hemorrhage].
It has been described a great variety of electrocardiographic abnormalities in the acute phase of the subarachnoid hemorrhage (SAH), which are more frequent in patients with severe neurologic impairment and when there is myocardial damage. The presence of electrocardiographic tracings compatible with acute myocardial infarction (AMI) in the acute phase of the SAH is rare. ⋯ It should pay more attention to the possibility of cardiac complications in the SAH. Myocardial ischemia and SAH may coexist. The presence of electrocardiographic abnormalities in the acute phase of the SAH is not always indicative of cardiac pathology.

Review[Nemaline congenital myopathy:clinical features and histopathological findings in nine patients].
Nemaline myopathy is a type of congenital myopathy which presents with hypotonia, muscle weakness which is predominantly proximal, lax ligaments, areflexia and skeletal deformities. It is characterized by the presence of intrasarcolemal or intranuclear rods which can be seen with the red color optical microscope using the Gomori technique, and a defect in the Z line of the sarcomere, detected on electron microscopy (EM). ⋯ There are no clinical features which permit distinction from other forms of congenital myopathy, so muscle biopsy is necessary for diagnosis. There is great phenotype and prognostic variety in this disorder.

Chronic intoxication due to carbon monoxide (CO) is a condition in which the frequency is underestimated since the clinical features are nonspecific. It is important since serious neurological sequelae may result: an extrapyramidal syndrome, dementia or a vegetative state. The diagnosis is established when there are venous blood levels of carboxyhemoglobin greater than 10%. Early treatment with hyperbaric O2 rapidly improves the symptoms and avoids the development of neurological sequelae. ⋯ Occult CO intoxication causes headache which often requires differential diagnosis from psychiatric disorders and episodes of migraine. In patients with refractory nonspecific headache, irregular course and systemic symptoms, usually in winter, CO intoxication should be considered to be a possible cause. Diagnosis is based on finding venous blood levels of carboxyhemoglobin of over 10%. Early treatment avoids lesion of the globus pallidus and irreversible extrapyramidal sequelae.
