Long-term follow-up of hereditary hemorrhagic telangiectasia patients without significant pulmonary right-to-left shunt at screening.

Objectives: To describe the incidence of pulmonary arteriovenous malformations (PAVM)-related complications, right-to-left shunt (RLS) progression at transthoracic contrast echocardiography (TTCE) and development of treatable PAVM during long-term follow-up in hereditary hemorrhagic telangiectasia (HHT) patients with RLS grades 0-1 at screening TTCE.

Methods: Observational prospective study including adult HHT patients with grades 0-1 RLS at screening TTCE. Those requiring previous embolization of PAVM were excluded.

[Normal values for transcranial doppler studies in our medium].

Objective: Transcranial Doppler is a technique which is being used ever more frequently in the study of intracranial arteries and is very useful in the study of cerebrovascular disease. The typical values of a healthy population in our country are unknown. The aim of this study was determine mean velocity and pulsatility index reference values in a healthy population.

[Acute sensory neuropathy associated with a varicella-zoster infection].

Introduction: Sensory neuropathy is a clinical entity which has been considered to be found in relation to neoplasia, Sjogren's syndrome, long-term pyridoxine treatment, or to be idiopathic.

Clinical Case: We present the case of a 33 year old woman who developed acute sensory neuropathy after being diagnosed as having varicella. She had no previous history of weight loss or other signs of neoplasia, no dryness of the mucous membranes or history of arthritis and had taken no toxic substances or pyridoxine, thus ruling out other causes of sensory neuropathy.

[Record of neurological emergencies at a tertiary care hospital].

Introduction And Objective: There is a progressive increase in the demand for multidisciplinary attention from the Emergency Medical Services. The objective of this study was to determine the proportion of neurological conditions in the total hospital emergency workload, their demographic composition and medical needs.

Patients And Methods: We present an observational study of a cohort of histories of neurological emergencies at a tertiary hospital during a period of one year.
