Clinical co-morbidities in obstructive sleep apnea syndrome treated with mandibular repositioning appliance.

INTRODUCTION: Intraoral mandibular repositioner appliances (IOMRAs) are designed to enlarge pharyngeal airway space advancing the mandible and increasing genioglossus tone during sleep. Obstructive sleep apnea syndrome (OSAS) treatment with IOMRAs is beneficial, but there is a lack of studies in the literature defining the target population more inclined to respond to this treatment. METHODS: We contacted by telephone 188 previously treated patients with IOMRA, detecting 20 not improved patients (Study Group). Twenty improved patients of the remaining 168 were randomly paired according to gender, age, apnea, and hypopnea index as Control Group. Both groups answered questionnaires for diagnosis of sleep disorders, depression, anxiety, and the Epworth sleepiness scale. We did a descriptive and inferential statistical analysis. The inferential analysis was divided into two steps: univariate analysis using Fischer exact test and a multiple inferential analysis using a stepwise regression model. RESULTS: Although the final model included only insomnia, we concluded that the presence of gastric, neurological and rheumatic diseases also tended to be associated with the self-perception of non-improvement. The association between the accumulation of gastric, neurological, and rheumatic diseases and insomnia and improvement demonstrated that an increase in one of these diseases correspond to a two-fold increase in the chance of non-improvement. CONCLUSIONS: Insomnia was the most important factor compromising the success of OSAS treatment with IOMRAs, and the isolated presence of gastric, neurological and rheumatic diseases, but especially their combination, reduces the perception rate of well-succeeded treatment with IOMRAs.

Cognitive dysfunction in children with sleep disorders.

UNLABELLED: Sleep is basic for physical and cognitive development and some studies have suggested that there may be an association between sleep disorders (SD) and cognitive dysfunction (CD) in children. Little is known, however, about SD and cognition in 7-10-year-old children, a fact that motivated the present study. METHOD: We applied an SD questionnaire in 1180 children, 547 with SD and 633 without SD (CG), to assess cognition with a screening test (Bender Visual Motor Gestalt Test - BT). RESULTS: We observed a similar frequency of CD in the children with SD (39%) and that ot the CG (40%). The 8-year-old children with SD presented a lower prevalence of CD than the CG (SD=6%, n=6; CG=13%, n=16; p=0.04). CONCLUSION: The frequency of children with CD was equal in the study and control groups when considering the total sample (7- to 10-year-old children). In contrast to our expectations, the SD group of 8-year-old children presented a lower frequency of CD than the control group.

Quality of life of patients with obstructive sleep apnea syndrome treated with an intraoral mandibular repositioner.

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is a very important and prevalent disease, which is associated with a poor quality of life in many patients. Treatments for OSAS include surgery, Continuous Positive Air way Pressure, and an intraoral mandibular repositioner (IOMR), but the tendency of sleep centers is to emphasize the apnea index, neglecting quality of life as treatment outcome. OBJECTIVE: To verify to what extent treatment with an IOMR improves the OSAS patient's quality of life. METHOD: Eleven male patients aged 34 to 63 years (mean=49) with mild to moderate OSAS were evaluated using the Calgary SAQLI questionnaire applied before and four weeks after treatment with an IOMR. The mandibular repositioners were manufactured individually for each patient with acrylic polymer and equipped with a retentive device to maintain the mandible in a forward position during sleep. RESULTS: Excellent improvement in the quality of life was observed in five patients (45.5%) and excellent improvement in symptoms in 10 (90.9%). CONCLUSION: The systematic use of the IOMR indicates a clear improvement in the global quality of life as well as in the symptoms of patients with OSAS.

Intermittent diazepam and continuous phenobarbital to treat recurrence of febrile seizures: a systematic review with meta-analysis.

UNLABELLED: Convulsions triggered by fever are the most common type of seizures in childhood, and 20% to 30% of them have recurrence. The prophylactic treatment is still controversial, so we performed a systematic review to find out the effectiveness of continuous phenobarbital and intermittent diazepam compared to placebo for febrile seizure recurrence. METHOD: Only randomized, double-blind, placebo-controlled trials were analyzed. The recurrence of febrile seizure was assessed for each drug. RESULTS: Ten eligible clinical trials were included. Febrile seizure recurrence was smaller in children treated with diazepam or phenobarbital than in placebo group. Prophylaxis with either phenobarbital or diazepam reduces recurrences of febrile seizures. The studies were clinical, methodological, and statistically heterogeneous. CONCLUSION: The effectiveness of phenobarbital and diazepam could not be demonstrated because clinical trials were heterogeneous, and the recommendation for treatment recurrence should rely upon the experience of the assistant physician yet.

Personality features in a sample of psychophysiological insomnia patients.

UNLABELLED: The personality is the way people express themselves inside the environment they live. Sleep, quality or quantity, is a way of this physical and psychological expression of well being. Psychological factors, associated with psychophysiological insomnia (PPI) suggest an exaggerated perception of the difficulties to fall asleep. Worries, anxiety and the fear of not sleeping produce a bad sleep quality or sleep misperception. This study aims to identify personality features associated with PPI throughout Rorschach test (RT). METHOD: We studied 32 patients with PPI (22 women), between 29 and 75 years old. We excluded patients with other sleeping or psychiatric disorders. We analysed the data from PPI patients submitted to the RT and we compared our results with the standard data. RESULTS: We noticed a significant increase in global answers and a significant decrease in detailed answers; a trend of a low number of answers; great number of shape and animal answers, especially for women. CONCLUSION: The features of the PPI patient's personality were daily problems insecure and the incapability to avoid or remove them from their thought, making bedtime a time for worries to appear again and motivate insomnia.
