Sleep quality and facial pain in fibromyalgia syndrome.

AIMS: This study aims to evaluate the sleep conditions in fibromyalgia syndrome and the influence of the temporomandibular disorders (TMDs) and fibromyalgia association in self-reported sleep quality. METHODOLOGY: Forty female patients with fibromyalgia (FMS) were compared with 40 healthy women [control group (CG)]. Three questionnaires were used (i.e. RDC/TMD to diagnose TMD and to determine pain intensity and disability and Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) to assess sleep conditions). Statistical analyses were performed using the Wilcoxon-Mann-Whitney test to ordinal variables, Student's t-test to obtain the quantitative total scores of PSQI and chronic pain classification, Spearman's rho to determine the correlation between facial pain and quality sleep, and Fisher's exact test for other variables. RESULTS: A moderate correlation between facial pain intensity and low sleep quality was found (rho = 0·56; P<0·0001); however, TMD and FMS association did not show worse sleep quality (P>0·05). Excessive daytime sleepiness was more prevalent in FMS (37·5%; P<0·0001) besides having the worst sleep quality (PSQI = 12·72) compared with CG (PSQI = 4·62). CONCLUSION: Fibromyalgia patients experience intense facial pain in addition to poor sleep and high disabilities. TMD and FMS association do not appear to worsen this condition; however, facial pain intensity was correlated with low sleep quality.

Stress and sleep quality in high school brazilian adolescents.

OBJECTIVE: The objective of the present study is to analyze the effect of stress on sleep quality in a group of adolescents. METHOD: Two high schools in Alfenas, southern Minas Gerais State, Brazil, were chosen to participate in the study. The sample consisted of both genders (n=160) with 65.63% females. The age range of participants was 15 to18 years. The Pittsburgh Sleep Quality Index (PSQI) was applied for collection of data to quantify sleep quality. The Lipp Inventory of Stress Symptoms that objectively identifies symptoms of stress was applied. RESULTS: It was observed that 23.53% of stressed students and 45.33% of unstressed ones sleep well; 76.47% of stressed pupils and 54.67% of those unstressed do not sleep well. With regard to school performance, a mean of 0.65 was found for stressed students and 0.60 for those without stress, Mann-Whitney (p=0.0596). CONCLUSION: Stress contributed to raising the percentage of poor sleepers, as ell as increasing ean school performance.

Quality of life in patients with narcolepsy: a WHOQOL-bref study.

OBJECTIVE: To evaluate the perception of Quality of Life (QL) in Brazilian patients with narcolepsy. METHOD: 40 adult patients aged between 20 and 72 years (mean=41.55; SD=14.50); (28 F; 12M), with the diagnosis of chronic narcolepsy were followed up at the outpatient clinic (Patient Group). The Control Group was composed of 40 adults. The instrument utilized was the World Health Organization Quality of Life (WHOQOL-BREF). RESULTS: The two groups were homogeneous and no difference was found with regards to age, sex, and demographic characteristics. The perception of QL in physical, psychological and social domains showed lower scores in those patients with narcolepsy than in the control group (p<0.05). Concerning physical domain, all the aspects evaluated were significantly impaired, in patient group, including sleep satisfaction (p<0.001); energy for daily activities (p=0.039); capacity to perform activities (p=0.001); and capacity to work (p=0.001). CONCLUSION: The perception of QL showed severe impairment in patients with narcolepsy for physical, psychological and social domains.

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). RESULTS: 91.30% of mothers reported poor sleep by PSQI standards. Regarding signs and symptoms of depression, 69.56% of all mothers in this sample showed them. Direct correlation between São Paulo mothers PSQI and BDI was found and also between the child's age and BDI. CONCLUSION: The mothers' poor sleep was related to mood changes with symptoms of depression presenting similar results in both cities.

Professor Antonio Branco Lefèvre: the forefather of child neurology in Brazil.

OBJECTIVE: To report on the life and works of Prof. Antonio Branco Lefèvre and the relevance that led him to be considered the Forefather of Child Neurology in Brazil. METHOD: The method utilized was the historical documents research; bibliographical. RESULTS: Antonio Branco Lefèvre (1916-1981) was born in São Paulo city; graduated in 1941 from the São Paulo Medical School. The date--1950--can be considered when Child Neurology took shape for a fully specialty, when Lefèvre presented his two internationally acclaimed thesis. Lefèvre was recognized as he founder of Child Neurology in Brazil since the early years of his brilliant academic activities. In 1967 achieved the title of professor in the Child Neurology Clinic. His numerous trainees and Residents--from -1950 to 1981--held today key positions in Brazilian Child Neurology. CONCLUSION: The extension and importance of the Child Neurology School of which he is the legitimate founder is recognized.

Nightly use of computer by adolescents: its effect on quality of sleep.

OBJECTIVE: To analyze the influence of nocturnal use of computer and their effect on sleep quality, in a group of adolescents. METHOD: Two middle schools were chosen for the research. The sample consisted of adolescents n=160 (55M; 105F), with ages ranging from 15 to 18 years. Questionnaire about computer use with the objective of obtaining information regarding the time and number of hours of nocturnal computer use, were applied for collection of data. They included the Pittsburgh Sleep Quality Index (PSQI), utilized to quantfy sleep quality; student report cards were used to note student's absences and grades were used. RESULTS: The Multiple Logistic Regression test indicated that nocturnal computer use impairs good sleep (p=0.0062). CONCLUSION: Irregular sleep patterns associated with nightly computer use deteriorate sleep quality.

Sleep disturbances in 50 children with attention-deficit hyperactivity disorder.

OBJECTIVE: This study assesses the relationship between sleep disturbances (SD) and attention-deficit and hyperactivity disorder (ADHD) to characterize clinical features and associated problems. METHOD: The medical records of 50 children and adolescents ranging in age from 4 to 17 years with ADHD without the diagnosis of mental retardation or pervasive developmental disorders were reviewed. RESULTS: Significant relationships were found between SD and drug therapy (p<0.01), co-morbidity (p<0.01) and greater adherence to treatment prescribed for ADHD disorders (p<0.05). CONCLUSION: The results of this study suggest that SD are an important problem in children with ADHD and may be linked to increased symptoms.

Dom João VI's death: convulsions and coma.

Dom João VI's death occurred in adverse political conditions that led to the regicide hypothesis. The main aim of this paper is to mention life style and conditions of the death of the king by means of narrative review based on primary and secondary sources. Dom João VI died in the way of convulsions and gastrointestinal symptoms. This could be the result of the pathological chain of genetic determination, accentuated by the inappropriate life style, obesity and sedentary habits, and/or poisoning. The finding of arsenic in high doses in his viscera favors the last hypothesis as the basic cause of death, but one can not discard the atherosclerosis predisposing risk factors for a final stroke.

Sleep habits, sleepiness and accidents among truck drivers.

OBJECTIVE: To evaluate the quality of sleep, shift work, alcohol and psychostimulant drug use, and the prevalence of accidents among truck drivers. METHOD: Data were collected using a demographic questionnaire, the Epworth Sleepiness Scale (ESS) and the Pittsburgh sleep quality index (PSQI). Statistical analysis was conducted using the Student t, chi-square, Pearson and Fisher tests. RESULTS: 43.2% of the drivers drove over 16 h a day, and 2.9% worked shifts. Mean number of sleep hours/day was 5.97+/-1.47; 23.8% slept <5 hours; 50.9% made use of alcohol, 95.6% of caffeine, and 11.1% of amphetamines. Mean PSQI was 4.95+/-2.56; 35.4% had a PSQI >5; 23 subjects snored more than three times a week (11.1%). Mean ESS was 6.56+/-4.2; 21.7% had a score >10. In the preceding five years, 27 drivers (13.1%) were involved in accidents, 5 of which resulted in injuries and 3 in deaths. CONCLUSION: Results showed a high prevalence of sleep disorders, use of alcohol and psychostimulant drugs, and accidents.

Frontal foramina, Chiari II malformation, and hydrocephalus in a female.

Reported is a 4-year-old female with Chiari II malformation and congenital hydrocephalus associated with lumbosacral myelomeningocele who also presented with frontal calvarial foramina depicted by head computed tomographic scans with three-dimensional reconstructions. Magnetic resonance demonstrated bilateral and symmetric frontal lobe malformation-separated-lip clefts schizencephaly-adjacent to the bilateral frontal calvarial foramina. Because the different types of malformations evident in this patient do not share the same developmental origin, the association of findings is unusual and suggests the occurrence of an unknown prenatal factor acting along different stages of central nervous system development.

Insomnia and hypnotic use in Campo Grande general population, Brazil.

The insomnia prevalence in general population was determined by means of 408 home interviews of adults, in a representative sample of Campo Grande city, Brazil. The random sample was stratified by sex, age and economic social status. Insomnia subtypes evaluated were the disorders of sleep initiation (DSI), sleep maintenance (DSM) and early awakening (DEA). A structured questionnaire was used with the consent from the interviewed subjects. Statistics used chi-square, and Fisher tests; and inferences based on binomial distribution parameters; the significance level was 5% and confidence interval (CI) was 95%. The general prevalence of insomnia was 19.1% (sd=2.0%), mostly women (p=0.0015), and people of less years of schooling (p=0.0317), subtype DSI (14.2%, p=0.0043), and chronic (p=0.7022). Hypnotic drugs were used by 6.9%(sd=1.3%) in the last month. Use in the last 2 years, 70.3% mostly insomniacs (p<0.0001), women (p=0.0372) and people over 30 years of age (p=0.0536).

Excessive daytime sleepiness in Campo Grande general population, Brazil.

The prevalence of excessive daytime sleepiness (EDS) in general population was determined by means of 408 home interviews of adults, in a representative sample of Campo Grande city, Brazil. The random sample was stratified by sex, age and economic social status. EDS was considered in those with indexes 11 or more in the Epworth Sleepiness Scale. Statistics used chi-square, Fisher and Pearson tests; and inferences based on binomial distribution parameters; the significance level was 5% and confidence interval (CI) was 95%. The prevalence of EDS was 18.9% of the general population ( SD=1.9%; CI 15.1% to 22.7%). No significant association was found between EDS and the use of hypnotics, nor with insomnia, body mass index, sex, age, years of schooling, economic social status, marital status, occupation and the use of alternative means to improve sleep. When the sample was separated according to sex, only the male group showed significant association between EDS and actual insomnia (p=0.005).

[Polysomnographic evaluation of clinical patients suffering from mood disturbance]. / Avaliação polissonográfica de pacientes ambulatoriais portadores de transtornos do humor.

The sleep patterns of sixty patients suffering from mood disturbance, were studied, with mean age of 36.1 +/- 11.3 years ( 12 males, 48 females). These patients were submitted to two nights of nocturnal polysomnographic evaluation; the second night acquired data was employed in the statistics. The following parameters were analyzed: parameters of sleep continuity, parameters of sleep architecture, REM and non-REM sleep parameters. The patients were analyzed in accordance to depression severity, presence of sleep disorders and relevant mood disturbances. The most common diagnosis was dysthymia in 25 cases (41.6%). Descriptive analysis was used to delineate the study. The statistics evaluation used the Fisher exact test and the Kruskal-Wallis statistics heterogeneity test. There was reduction in sleep continuity and increase in REM density, both not statistic significant. Stage 4 sleep showed significant reduction in severely depressed patients (p=0.0253).

Analysis of the prevalence of insomnia in the adult population of São José do Rio Preto, Brazil.

OBJECTIVE: To establish the prevalence of insomnia in the adult urban population of São José do Rio Preto, Brazil and correlate it with the demographic data. METHOD: We evaluated 1105 individuals in to guarantee an error margin of 3% and a confidence level of 95% using a structured questionnaire and following the DSM-IV and DSM-III-R criteria, in the period from January 10 to February 28 2001. RESULTS: We encountered a prevalence of 32% of insomnia, which was most commonly seen in women, single people, from the lower economical brackets, with a low level of schooling and it was less associated with younger adults (18-31 year-olds). CONCLUSION: Our findings indicate that the prevalence of insomnia in the adult population of São José do Rio Preto is comparable with other countries such as the USA and those of Europe and also with other cities in Brazil.

Schwartz-Jampel syndrome: report of five cases.

We describe five patients with Schwartz-Jampel syndrome (SJS) examined at the outpatient service for neuromuscular disorders at our Institution from 1996 to 1999 with the objective of emphasizing the characteristic dysmorphic phenotype of SJS and its different clinical forms. Two cases presented SJS-type 1A, two had SJS-type 1B and one manifested SJS-type 2. Two boys with 3 and 13 years of age had generalized stiffness and the characteristic facial as well as osteoarticular changes from birth. Other two boys with 11 and 7 years had less marked dysmorphic changes at birth and manifested myotonia, as a limiting factor, during the second year of age. A girl with two months of age had severe myotonia from birth leading to feeding difficulties. In all cases the diagnosis was based on dysmorphic features, and on electromyographic changes showing continuous electrical activity of muscle fibers. All were treated with carbamazepine, 20-30 mg/Kg since diagnosis. The four boys (all with normal intelligence) improved of myotonia in daily activities, markedly in three, and moderately in one. The girl did not improve and showed global development delay: by the last follow-up (at 20 months of age) she did not sit unsupported, and had mental retardation. Carbamazepine in SJS-type 1 improves general daily performance and psychological status of the patients.

Quality of life in children with narcolepsy.

AIMS: To evaluate the health-related quality of life (HRQL) and its correlates in children and adolescents with narcolepsy. METHODS: We compared the clinical characteristics of control subjects and patients with primary narcolepsy from data collected at the National Reference Centers for Narcolepsy. RESULTS: The cohort included 69 control subjects (29 boys) and 117 patients (65 boys; 59 de novo patients). Cataplexy was present in 81% and DQB1*0602 was positive in 91%. The control children were older (13.5±3.2 vs. 11.6±3.1 years, P<0.001) and less obese (1.4% vs. 60%, P<0.001). Twenty-five percent of the patients and 15.6% of the control subjects had clinically significant depressive feelings on Children's Depression Inventory (CDI≥16) (NS). Fifty-three narcoleptic and 43 control adolescents, 31 narcoleptic children and 23 control children filled out the HRQL questionnaires as well as 83 parents of patients and 60 parents of control subjects. Narcolepsy seriously impacts HRQL in terms of vitality, physical well-being, relations with friends and leisure activities, especially in adolescents. Depression was the factor that most affected HRQL in both narcoleptic and control subjects. For the control subjects and the narcoleptic patients, when the CDI score was entered into the multivariable regression model adjusted for gender and age, no other continuous independent variable could significantly increase the likelihood of the model. When the CDI score increased by 1, the mean HRQL score decreased by 1.7 for narcoleptic patients and 1.5 for control subjects. Apnea-hypopnoea index, diagnosis delay, disease duration, obesity, the presence of cataplexy or treatment had no effects on HRQL. CONCLUSIONS: Narcoleptic children and adolescents were at high risk for poor HRQL. Depressive symptoms had a major impact on HRQL. We recommend a more thorough assessment and management of psychological health in this population.

Depressive feelings in children with narcolepsy.

OBJECTIVES: We aimed to evaluate depressive feelings and their correlations in children and adolescents with narcolepsy collected in national reference centers for narcolepsy. METHODS: We compared clinical and sleep characteristics of patients with and without depressive symptoms evaluated on the Children's Depression Inventory (CDI). RESULTS: Our study sample included 88 children (44 boys; 44 de novo patients) with a mean age of 11.9 ± 3.1 years at diagnosis (37.5% were aged ⩽ 10 years). Obesity was found in 59% of the sample and cataplexy was present in 80.7%. The DQB1*0602 allele was positive in 93.5% of our sample. There were 25% of children who had clinically depressive feelings (CDI>16), especially girls older than the age of 10 years. Bivariate associations indicated that depressive feelings were associated with fatigue (48%), hyperactivity (31%), insomnia (16%), and excessive daytime sleepiness (EDS) (14-24%). In the multivariate model adjusted for gender and age, only fatigue explained the variability of the depression score. CONCLUSION: In our large cohort, high levels of depressive symptoms essentially expressed by fatigue affected 25% of children with narcolepsy. The girls older than 10 years of age were especially vulnerable. The similar prevalence of depressive feelings in treated vs never-treated patients suggests a specific need for diagnosing and managing this symptom in young patients with narcolepsy.

Quality of life and sleep in obese adolescents.

UNLABELLED: Obesity and sleep disorders in adolescence are strongly associated, and they impact both on the health and on quality of life (QL) in this age group. OBJECTIVE: To comparatively assess QL and sleep in obese and eutrophic adolescents, who are older than ten years of age. METHODS: Cross-sectional study including obese adolescents. This analysis was carried out between August 2009 and August 2010. The Control (eutrophic) Group comprised schoolchildren recruited from State schools in the city of Americana, in São Paulo State, Brazil. Instruments applied included a standardized questionnaire, the Sleep Behavior Questionnaire (SBQ), and the Pediatric QL Inventory (PedsQL TM 4.0). RESULTS: The obese adolescents had poorer QL on physical (p<0.001), emotional (p=0.03), and social (p=0.002) functioning domains. A difference in mean psychosocial functioning was found between the groups (p=0.009) with obese subjects having a mean score of 69.5 (±16.0) and in eutrophic individuals of 76.2 (±16.7). A greater number of sleep problems was evident in the Obese Group (p=0.03). CONCLUSIONS: The obese adolescents had an impaired QL and a higher frequency of sleep problems compared to the eutrophic subjects.

Facial pain associated with fibromyalgia can be marked by abnormal neuromuscular control: a cross-sectional study.

BACKGROUND: Temporomandibular disorder (TMD) development in fibromyalgia syndrome (FMS) is not yet fully understood, but altered neuromuscular control in FMS may play a role in triggering TMD. OBJECTIVE: The purpose of this study was to verify the association between neuromuscular control and chronic facial pain in groups of patients with FMS and TMD. DESIGN: A cross-sectional study was conducted. METHODS: This study involved an analysis of facial pain and electromyographic activity of the masticatory muscles in patients with FMS (n=27) and TMD (n=28). All participants were evaluated according to Research Diagnostic Criteria for Temporomandibular Disorders and surface electromyography (SEMG). Myoelectric signal calculations were performed using the root mean square and median frequency of signals. RESULTS: The data revealed premature interruption of masticatory muscle contraction in both patient groups, but a significant correlation also was found between higher median frequency values and increased facial pain. This correlation probably was related to FMS because it was not found in patients with TMD only. Facial pain and increased SEMG activity during mandibular rest also were positively correlated. LIMITATIONS: Temporal conclusions cannot be drawn from the study. Also, the study lacked a comparison group of patients with FMS without TMD as well as a control group of individuals who were healthy. CONCLUSIONS: Altered neuromuscular control in masticatory muscles may be correlated with perceived facial pain in patients with FMS.

Impact of obesity in children with narcolepsy.

AIMS: To evaluate the impact of obesity on clinical and sleep characteristics in a population of narcoleptic children. METHODS: Data from the children diagnosed with idiopathic narcolepsy in the National Reference Centers for Narcolepsy were collected between 2008 and 2011. Clinical and electrophysiological characteristics were compared between obese (body mass index [BMI] greater than P97) and nonobese children. RESULTS: The 117 children (65 boys, 59 de novo patients) had a mean age of 11.6 ± 3.1 years on diagnosis. Cataplexy was present in 81%, DQB1*0602 in 91%. Mean BMI was 23.2 ± 5.2 kg/m(2) and BMI z-score was 2.9 ± 2.6. Obesity was found in 60% with a similar prevalence in treated versus de novo patients and in patients with and without cataplexy. Sleepiness and cataplexy started earlier in obese children. Obese narcoleptic children had lower sleep efficiency, higher apnea hypopnea index and respiratory arousals index (RAI) than nonobese children. BMI z-score was positively correlated with RAI. Obese children were more tired and missed more often school than nonobese children. CONCLUSION: Obesity affects more than 50% of narcoleptic children, mostly younger at disease onset, and has a deleterious impact on sleep quality as well as on school attendance.
