Caracterización clínico-espirométrica de pacientes asmáticos con síntomas nocturnos / Clinical-spirometric characterization of asthmatic patients with nocturnal symptoms

Introducción: Los síntomas nocturnos son frecuentes en asmáticos y pueden relacionarse con la gravedad, el grado de control del asma y la función pulmonar. Objetivos: Determinar las características demográficas, clínicas y espirométricas de pacientes asmáticos con síntomas nocturnos, que acuden a consulta externa de neumología. Métodos: Se realizó un estudio descriptivo transversal en 50 pacientes asmáticos con síntomas nocturnos, atendidos por consulta externa en el Hospital Neumológico Benéfico Jurídico, en el período comprendido de mayo de 2017 a mayo de 2018. Resultados: Predominó el sexo femenino (74,0 por ciento), la edad entre 40 y 59 años (52,0 por ciento), los antecedentes familiares de asma o alergia (60,0 por ciento) y múltiples comorbilidades asociadas (78,0 por ciento). La hipersomnia diurna estuvo presente en 80,0 por ciento de los casos, con una frecuencia significativamente elevada en pacientes con asma persistente moderada y severa, disminución de la reversibilidad aguda al broncodilatador, mal control de la enfermedad y limitación de la actividad física. Conclusiones: Los síntomas nocturnos en los pacientes asmáticos son frecuentes y se relacionan con la hipersomnia diurna, la gravedad del asma, el grado de control, la respuesta al broncodilatador y limitación de la actividad física(AU)

Introduction: Nighttime symptoms are frequent in asthmatics and can be related to severity, degree of asthma control and lung function. Objectives: To determine the demographic, clinical and spirometric characteristics of asthmatic patients with nocturnal symptoms, who go to an outpatient pulmonology clinic. Methods: A descriptive cross-sectional study was conducted in 50 asthmatic patients with nocturnal symptoms, they were assisted in the outpatient consultation at the Hospital Neumológico Benéfico Jurídico, from May 2017 to May 2018. Results: Female sex (74.0 percent), age ranging 40 and 59 years (52.0 percent), family history of asthma or allergy (60.0 percent) and multiple associated comorbidities (78.0 percent) predominated. Daytime hypersomnia was present in 80.0 percent of cases, with significantly elevated frequency in patients with moderate and severe persistent asthma, decreased acute reversibility to the bronchodilator, poor disease control, and limited physical activity. Conclusions: Nocturnal symptoms in asthmatic patients are frequent and are related to daytime hypersomnia, asthma severity, degree of control, response to the bronchodilator and limitation of physical activity(AU)

Narcolepsy with Obstructive Sleep Apnea in a 4-Year-Old Korean Girl: A Case Report

A 4-yr-old girl has exhibited severe snoring, restless sleep and increasing daytime sleepiness over the last 3 months. The physical examination showed that she was not obese but had kissing tonsils. Polysomnography demonstrated increased apnea-hypopnea index (AHI) of 5.2, and multiple sleep latency tests (MSLT) showed shortened mean sleep latency and one sleep-onset REM period (SOREMP). She was diagnosed with obstructive sleep apnea (OSA) and underwent tonsillectomy and adenoidectomy. After the surgery, her sleep became much calmer, but she was still sleepy. Another sleep test showed normal AHI of 0.2, the mean sleep latency of 8 min, and two SOREMPs. Diagnosis of OSA to be effectively treated by surgery and narcolepsy without cataplexy was confirmed. Since young children exhibiting both OSA and narcolepsy can fail to be diagnosed with the latter, it's desirable to conduct MSLT when they have severe daytime sleepiness or fail to get better even with good treatment.

Narcolepsy: Clinical features, co-morbidities & treatment.

Narcolepsy is a neurologic illness that typically begins in the second and third decades of life. It is chronic in nature and negatively impacts the quality of life of affected patients. The classic presentation is a tetrad of excessive daytime sleepiness, cataplexy, sleep paralysis, and hypnagogic hallucinations. The exact cause remains unknown, but there is significant evidence that hypocretin deficiency plays an integral role. Some primary conditions that result in secondary narcolepsy include traumatic brain injury, congenital disorders, tumours, and strokes. Some medical and psychiatric disorders share characteristics of narcolepsy, at times leading to diagnostic inaccuracy. Other sleep disorders are commonly co-morbid. Diagnosis relies on patient history and objective data gathered from polysomnography and multiple sleep latency testing. Treatment focuses on symptom relief through medication, education, and behavioural modification. Both classic pharmacological treatments as well as newer options have significant problems, especially because of side effects and abuse potential. Novel modalities are being examined to expand options for treatment.

Narcolepsia: diagnóstico diferencial nas síncopes não explicadas / Narcolepsy: differential diagnostics in the unexplained syncopes

A narcolepsia é uma doença com alta prevalência, frequentemente subdiagnosticada. Suas manifestações mais comuns, a hipersonolência e a cataplexia, muitas vezes podem simular episódios de síncope. Esta revisão tem o objetivo de esclarecer os mecanismos fisiopatológicos dessa patologia, assim como suas manifestações clínicas e seu manejo. Dessa forma, espera-se contribuir para que o médico a reconheça e a diferencie das causas mais frequentes de síncope.

Narcolepsy and depression

Narcolepsy main symptoms include excessive daytime sleepiness and cataplexy. Its chronic course is accompanied by phychosocial impairment added to the difficulties and side effects of stimulants and tricyclics long term use. Depressive complaints are occasionally reported. The aim of this paper was to evaluate objectively the possibility of depression in a sample of 12 narcoleptics (7F;5M), with mean age of 53 years (12 years SD), using the Beck Depression Inventory (BDI) and the Hamilton Rating Scale for Depression (HAM-D). The results showed absence of depressive disorder in 75.0 percent of the cases according to BDI (or 58.3 percent according to HAM-D). The remaining patients had mild depression (only one patient presented major depression). The findings showed no correlation between narcolepsy and major depression.

Narcolepsia e apnéia do sono concomitantes: registro de caso / Concomitant narcolepsy and sleep apnea: report of a case

Relata-se um caso de concomitância de narcolepsia e apnéia do sono tipo obstrutiva documentado clinicamente e em traçados polissonográficos em laboratório de sono. Após correçäo cirúrgica da apnéia do sono, com traqueostomia, houve manutençäo da sintomatologia narcoléptica e de seu registro característico. Este estudo apóia a necessidade de emprego sistemático da polissonografia de noite inteira e do teste de latência múltipla do sono na avaliaçäo de pacientes com sonolência excessiva diurna
