Case report: Diagnosis and intervention of a non-24-h sleep-wake disorder in a sighted child with a psychiatric disorder.

Circadian rhythm sleep-wake disorders (CRSWD) are sleep dysfunctions related to circadian functioning. They are characterized by symptoms of insomnia or excessive sleepiness that occur because the intrinsic circadian pacemaker is not entrained to a 24-h light/dark cycle. Affected individuals with a free-running disorder or hypernycthemeral syndrome (N24SWD) have a longer sleep-wake cycle that produces a sleep pattern that typically delays each day.

Application of Machine Learning Methods to Ambulatory Circadian Monitoring (ACM) for Discriminating Sleep and Circadian Disorders.

The present study proposes a classification model for the differential diagnosis of primary insomnia (PI) and delayed sleep phase disorder (DSPD), applying machine learning methods to circadian parameters obtained from ambulatory circadian monitoring (ACM). Nineteen healthy controls and 242 patients (PI = 184; DSPD = 58) were selected for a retrospective and non-interventional study from an anonymized Circadian Health Database (https://kronowizard.um.

Ambulatory circadian monitoring (ACM) based on thermometry, motor activity and body position (TAP): a comparison with polysomnography.

An integrated variable based on the combination of wrist Temperature, motor Activity and body Position (TAP) was previously developed at our laboratory to evaluate the functioning of the circadian system and sleep-wake rhythm under ambulatory conditions. However, the reliability of TAP needed to be validated with polysomnography (PSG). 22 subjects suffering from sleep disorders were monitored for one night with a temperature sensor (iButton), an actimeter (HOBO) and exploratory PSG.

Clinical and polysomnographic correlation in sleep-related breathing disorders in children.

Introduction: Although polysomnography is the gold standard test for sleep-disordered breathing in children, there is controversy about its indication in all cases. Among the arguments both for and against is the lack of correlation between objective values and the symptoms.

Objective: To evaluate the correlation between clinical data and apnea-hypopnoea index (AHI) in our work environment.

Insomniac children maternal sleep and mood in São Paulo and Barcelona.

Objective: To evaluate sleep characteristics verifying for the presence of depressive symptoms in mothers of insomniac children living in São Paulo (Brazil) and Barcelona (Spain).

Method: Forty-six mothers were evaluated, 37 from São Paulo and nine from Barcelona, their ages varying from 19 to 44, and their children; otherwise healthy but with complaints of insomnia, their age varying from three to 33 months. The mothers' sleep quality was rated by the Pittsburgh Sleep Quality Index (PSQI), and the Beck Depression Inventory (BDI).

Nocturia in Spanish patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH).

Objective: This study aimed to assess the prevalence of nocturia and its impact on quality of life (QoL) in Spanish patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH).

Research Design And Methods: This was a Spanish, multicentre, cross-sectional study. Outpatients aged 60 years and over with LUTS/BPH, a prostate size > or = 25 g, untreated for LUTS/BPH and responding to the International Prostate Symptom Score (I-PSS) were included.

Continuous versus non-nightly use of zolpidem in chronic insomnia: results of a large-scale, double-blind, randomized, outpatient study.

New treatment strategies are encouraged in insomnia and, in particular, discontinuous treatment. The aim of this double-blind study was to compare, in a large primary care population of chronic insomniacs (> 4 weeks duration) the efficacy and safety of zolpidem 10 mg 5 nights/week and placebo 2 nights/week, to that of nightly zolpidem. Seven hundred and eighty-nine drug-free insomniacs, with a Total Sleep Time (TST) of 3-6 h/night were enrolled in seven European countries.
