Serum neuron-specific enolase and S100 calcium binding protein B biomarker levels do not improve diagnosis of acute stroke.

Background: The high sensitivities and specificities reported for blood biomarkers as a supportive test in the diagnosis of acute stroke do not correspond with their performance for decision-making in emergency situations.

Methods: Seventy-two patients with suspected stroke were recruited: 44 with ischaemic stroke, 17 with haemorrhagic stroke and 11 stroke mimics, as well as a high-risk control group of 79 individuals. Serum neuron-specific enolase (NSE) and S100 calcium binding protein B (S100B) biomarker levels were determined on admission, using immunoassay kits.

High proportion of mannosidosis and fucosidosis among lysosomal storage diseases in Cuba.

Although lysosomal storage disorders (LSDs) are considered individually rare, as a group they present a non-negligible frequency. Few studies have been made of populational occurrence of LSDs; they have been conducted predominantly on Caucasian populations. We studied the occurrence of LSDs in Cuba.

Short-term prognostic value of serum neuron specific enolase and S100B in acute stroke patients.

Objective: To explore the value of blood markers for brain injury as outcome predictors in acute stroke.

Design And Methods: The study included 61 patients with acute stroke (44 ischemic and 17 hemorrhagic) and a high risk control group (79 individuals with no known history of neurological disease). Serum neuron specific enolase (NSE) and S100B were determined by immunoassay (CanAg Diagnostics, Sweden).

[Mucopolysaccharidosis: 20-year enzymatic diagnosis in Cuba].

Introduction: Mucopolysaccharidoses (MPS), which belong to the family of inborn errors of metabolism, are characterised by their severe clinical manifestations (skeletal, neurological and visceral) and a chronic, progressive course leading to death at early stages of life. AIM. To accomplish an enzymatic diagnosis and characterise MPS within the Cuban population.
