Sleep apnoea syndromes have been known since long, and frequently the presenting symptoms are neurological in nature. However, these disorders have not been systematically studied and reported in the Indian literature. Out of 12,000 neurology outpatients seen by authors in 2 years, 60 had primary sleep disturbances. All these 60 patients underwent clinical evaluation and video EEG polysomnography. In 8 out of 60 (13%) patients, sleep apnoea was documented. Five patients had obstructive sleep apnoea, 3 had mixed sleep apnoea and none had pure central sleep apnoea syndrome. Three-fourths of the patients were obese (mean weight 82kg) middle aged males (mean age 46.3 years). The main symptoms encountered were excessive daytime somnolence and snoring. The symptom severity was found to correspond directly with the duration of symptoms as well as obesity. Sleep apnoea syndromes must be seriously considered and documented in all patients complaining of excessive daytime somnolence.

Craniopharyngioma is a rare dysontogenetic benign tumor. Patients frequently suffer from endocrine deficiencies, sleep disturbances, and obesity due to pituitary and hypothalamic lesions. A self-assessment daytime sleepiness questionnaire (German version of the Epworth Sleepiness Scale) was used to evaluate 79 patients with childhood craniopharyngioma. Because hypothalamic lesions may explain daytime sleepiness in craniopharyngioma patients, salivary melatonin and cortisol concentrations were examined in obese and nonobese craniopharyngioma patients (n = 79), patients with hypothalamic pilocytic astrocytoma (n = 19), and control subjects (n = 30). Using a general linear model procedure analyzing the influence of body mass index (BMI) and tumor diagnosis on diurnal salivary melatonin, we found that morning salivary melatonin levels were related to BMI (by F test, P = 0.004) and tumor diagnosis (by F test, P = 0.032). Also for nighttime salivary melatonin levels significant relations with BMI (by F test, P < 0.001) and tumor diagnosis (by F test, P = 0.025) were detectable. Melatonin concentrations in saliva of craniopharyngioma patients collected at night or in the morning showed a negative correlation (night: Spearman's rho = -0.42; P = 0.001; morning: Spearman's rho = -0.31; P = 0.020) with the patient's Epworth Sleepiness Scale score. Severely obese craniopharyngioma patients and severely obese hypothalamic tumor patients had similar patterns of melatonin secretion. Differences in terms of diurnal salivary cortisol concentrations were not detectable when patient groups and controls were compared. We speculate that hypothalamic lesions might be responsible for both obesity and daytime sleepiness. As decreased nocturnal melatonin levels were associated with increased daytime sleepiness, BMI, and hypothalamic tumor diagnosis, further studies on the beneficial effects of melatonin substitution on daytime sleepiness and weight control in these patients are warranted.

Obesity has reached epidemic proportions in the U.S. and more developed countries, particularly so among adolescents. A substantial impact on public health could be achieved if other factors causing obesity besides the conventional ones of diet and physical activity could be identified and acted upon. The present study investigates whether there is a link between low sleep quality and obesity in a tri-ethnic, cross-sectional sample (n = 383) of male and female adolescents ages 11-16 years old (Heartfelt Study). Sleep quality was expressed as two variables, total sleep time and sleep disturbance time obtained by 24-hour wrist actigraphy. Percent body fat and body mass index (BMI) were used together to define obesity. The potential influence of demographic and behavioral confounders were considered in models that described the relation of sleep to obesity occurrence. Obese adolescents experienced less sleep than nonobese adolescents (P < 0.01). For each hour of lost sleep, the odds of obesity increased by 80%. Sleep disturbance was not directly related to obesity in the sample, but influenced physical activity level (P < 0.01). Daytime physical activity diminished by 3% for every hour increase in sleep disturbance. The above observations were independent of potential confounding variables. Inadequate and poor sleep quality in adolescents may be important factors to consider in the prevention of childhood obesity.

A cross-sectional study was carried to find out the lifestyle pattern and morbidity profile of geriatrics residing in urban community of Vikram Nagar, Delhi. Women constituted 56.25% and men 43.75% of a total of 128 study subjects. Hindus were 89.06% and Sikhs 10.93%. Age group of 60-75 years accounted for most of the study population. 85% of the subjects complained of one or more health problems. 90.62% of them suffered from dental problems. A significantly higher proportion of women suffered from problems of locomotion/joints and anemia as compared to men whereas genitourinary problems were higher in men as compared to women. 42.55 of the women and 30.76% of the men were obese. Current smokers constituted 15.62% of the women and 30.76% of the men were obese. Current smokers constituted 15.62% of the population whereas 30.35% of the men were current consumers of alcohol. 12.5% used tobacco. As low as 10.15% of the population engaged in regular physical activity. 55.46% of the subjects were vegetarian. 22.65% suffered from disturbed sleep pattern. Smoking showed statistically significant association with hypertension and respiratory tract diseases. Physical activity showed association with obesity and disorder of locomotion. Behavior and lifestyle modification in the form of primordial prevention and counseling of the high risk groups should be carried to improve the quality of life of the aged.

To determine the prevalence of fibromyalgia in diabetes mellitus and obesity, 121 consecutive patients have been observed: 27 with obesity (6 males and 21 females; mean age 57 years, range 20-57; mean body mass index [BMI] 34); 88 with type 2 diabetes mellitus (T2DM; 40 males and 48 females; mean age 63 years, range 44-78; mean BMI 28.8; mean glycated haemoglobin [HbA1c] in the last year 8.3%); 6 with type 1 diabetes mellitus (T1DM; 2 males and 4 females; mean age 52 years, range 26-76; mean BMI 24.5; mean HbA1c < 7%). An original questionnaire has been proposed (answer yes/not) as follows: 1) chronic (more than 3 months) and diffuse musculoskeletal pain; 2) sleep disturbances; 3) generalized fatigue; 4) paresthesias at the extremities; 5) swollen impression at hands and feet; 6) symptoms referred to irritable bowel syndrome; 7) headache; 8) symptoms change related with environmental climatic variations and/or exercise. A chronic and diffuse musculoskeletal pain has been reported by 62% of patients as well as in 9% of patients 11/18 positive tender points have been documented. In the patients with a BMI less that 26 the diagnosis of fibromyalgia was negative. Our data seem to reveal the presence of a significant clinical association between obesity, diabetes mellitus and fibromyalgia.

In this article, the authors review current concepts in fibromyalgia. Findings regarding diagnosis, prevalence, comorbidities, and potential pathophysiologic links are discussed. Although fibromyalgia continues to be a complex disorder, there are specific criteria one must meet. Fibromyalgia questionnaires, along with commonalities of age, gender, menopause status, sleep disturbances, and mood symptoms, may aid in the diagnosis. Additionally, the close relationship between fibromyalgia and other chronic disorders should alert the physician to explore for comorbid illness. The relationship between fibromyalgia and irritable bowel syndrome, migraine headaches, and obesity are addressed. The roles of the hypothalamic-pituitary-axis, potential effects of neurotransmitters, and gender-specific hormones all substantiate this diagnosis and provide clues to causality, as well as venues for future treatment.

C-reactive protein (CRP) is an acute-phase reactant whose levels increase in response to a variety of inflammatory stimuli. Elevated levels in serum are observed after trauma, tissue necrosis, infection, surgery, and myocardial infarction and are associated with an increased risk of cardiovascular disease. CRP levels are also elevated in noninflammatory states, such as obesity, sleep disturbances, depression, chronic fatigue, aging, and physical inactivity. In this study, the performance of a highly sensitive CRP enzyme immunoassay was evaluated, along with common laboratory variables (specimen type, processing time, and storage conditions) that may influence measured blood concentrations of CRP. The measurement range of the assay was from 0.4 to 50 microg/liter. Total imprecision (coefficient of variation) ranged from 8.1 to 11.4%. CRP levels obtained with the enzyme immunoassay were highly correlated with those obtained with an automated immunonephelometric assay. Comparable results were obtained for plasma (heparin and EDTA treated) and serum samples, and levels were unaffected by delays in sample processing and storage temperature. CRP levels were also unaffected by up to seven freeze-thaw cycles. The median CRP concentration in healthy adults was determined to be 0.94 mg/liter, with a 95% working reference interval of 0 to 6.9 mg/liter. In view of these data, we recommend that serial serum or plasma samples for CRP should be stored at 4 degrees C for short periods of time or at -70 degrees C for longer periods and tested within the same run to minimize interassay variability.

Epidemiological studies have shown a strong association between sleep-disordered breathing (SDB) and cerebrovascular diseases. A total of 114 male patients, aged 40-65 years, referred to sleep laboratory for the evaluation of snoring and disturbed sleep were studied. Subjects were divided into three groups: habitual snoring, mild-moderate and severe obstructive sleep apnea syndrome (OSAS), respectively, determined by using three respiratory disturbance index (RDI) cut points (</=5, 5 < RDI < 30 and >/=30). Measurement of intima-media thickness (IMT) and the presence of plaque were determined by ultrasonographic evaluation. Major vascular risk factors such as hypertension, diabetes, smoking, hyperlipidemia, and obesity were determined. The OSA groups had significantly higher IMT values compared with the habitual snoring group. Three groups were significantly different with regard to the presence of plaque. Age and body mass index were found to be significantly associated with IMT while age and RDI were found to be most probably predictive for plaque. There were no significant differences amongst the three groups with respect to age, prevalence of hypertension and diabetes, smoking, total cholesterol and total triglyceride levels. These findings suggested that SDB is a predisposing factor for the atherosclerotic process and precipitate plaque particularly when associated with higher RDI.

Sleep disturbances have a major impact on physical functioning, emotional well-being, and quality of life, but are not well described in patients with heart failure (HF). Eighty-four HF patients completed a sleep survey and provided demographic and clinical data. Seventy percent of the patients were male with a mean age of 54 years and a mean left ventricular ejection fraction of 22%. Forty-seven patients (56%) reported trouble sleeping and one-third used sleeping medication. The most frequently reported problems were inability to sleep flat (51%), restless sleep (44%), trouble falling asleep (40%), and awakening early (39%). Using logistic regression, physiological variables were tested as predictors of sleep disturbance. Severity of HF, age, gender, etiology, obesity, smoking, and use of beta-blockers were not predictors of sleep disturbance. HF patients experience significant sleep disturbances, which are not predicted by severity of symptoms or clinical status. Problems with sleep are an important component of a clinical assessment in this vulnerable population.

Sleep problems are common in many pediatric medical disorders and complicate management and patient outcomes. A wide range of conditions, including asthma, cystic fibrosis, sickle cell disease, gastroesophageal reflux, neuromuscular diseases, scoliosis, craniofacial abnormalities, obesity, and chromosomal disorders, have various sleep disturbances, including sleep-disordered breathing, ventilatory dysfunction, sleep-onset and sleep maintenance problems, and circadian rhythm disturbances. Given the adverse neurocognitive and physiologic outcomes associated with a deranged night's sleep, it is important for pediatricians to be able to anticipate, recognize, and appropriately manage these problems. This article reviews the known sleep-related problems of a few relatively common pediatric disorders.
