[Sleep paralysis during naptime as initial symptom of narcolepsy].

Introduction: Narcolepsy is a disease of unknown etiology, with a very low prevalence (0.02-0.16% in adults, although it must be higher, given the underdiagnosis), characterized by the presence of excessive daytime sleepiness, hypnagogic and/or hypnopompic hallucinations, sleep paralysis and/or cataplexy (if present, we speak of type 1 narcolepsy and, if not, type 2 narcolepsy), whose average diagnostic delay is between 10 and 15 years.

Mature filum terminale teratoma. Excision guided by direct stimulation of nerve roots.

A 45-year-old male patient, with no history of interest, consulted in emergency department due to a progressive loss of strength in the lower limbs at the distal level with impossibility for dorsal flexion of the left foot, as well as neurogenic bladder. The MRI revealed a mass at the filum terminale with completed occupation of transverse diameter of the dural sac. The radiological diagnosis was lipoma of filum terminale.

Gamma glutamyl transferase and oxidative stress in obstructive sleep apnea: a study in 1744 patients.

Objective: We analyze a large population of patients to determine whether gamma glutamyl transferase (GGT) levels are increased in sleep apnea-hypopnea syndrome (OSA) and whether these levels are related to clinical characteristics or polygraphic indexes.

Methods: A cross-sectional study in a population of 1744 patients referred for OSA suspicion was conducted. The following variables were determined: glucose, cholesterol, triglycerides, aspartate aminotransferase (GOT), alanine aminotransferase (GPT), GGT, body mass index, waist-hip ratio (WHR), and overnight sleep study.
