The risk factors of cardiovascular disease and other disease comorbidities appear to be more common in patients with psoriasis compared with the general population. To support this concept, the association between psoriasis and cardiovascular disease and other comorbidities was analyzed using data collected from 40 730 patients in the National Health and Wellness Survey (NHWS) during May and June 2004. A case-control study was conducted with data from 1127 patients with psoriasis and a matched cohort of nonpsoriasis patients. Psoriasis patients were significantly more likely to have cardiovascular comorbidities, including hypertension, hypercholesterolemia, and diabetes, compared with nonpsoriasis patients. Other comorbidities significantly associated with psoriasis were arthritis, depression, sleep disorder/insomnia, chronic obstructive pulmonary disease, and gastroesophageal reflux disease. Responses to this large survey confirm that patients with psoriasis have a higher rate of cardiovascular risk factors and other comorbidities compared with patients without psoriasis.

Gastroesophageal reflux disease (GERD) and sleep disturbances are both common health problems. There is a significant association between disturbed sleep and GERD, and this may be bidirectional. Sleep disorders may induce gastrointestinal (GI) disturbances, while GI symptoms also may provoke or worsen sleep derangements. Reflux of gastric acid is a less frequent event during sleep, however, acid clearance mechanisms (including swallowing, salivation and primary esophageal motility) are impaired during sleep resulting in prolongation of acid contact time. Nighttime reflux can lead to sleep disturbance and sleep disturbance may further aggravate GERD by prolonged acid contact time and heightened sensory perception. This may facilitate the occurrence of complicated GERD and decreased quality of life. However, the interplay between sleep problems and GERD is complex, and there are still relatively limited data on this issue. Further investigation of sleep-related GERD may identify common pathophysiological themes and new therapeutic targets.

Apnea of prematurity (AOP) is a developmental sleep disorder which is yet to be completely understood. Although there is some evidence of brainstem immaturity, there is nothing to suggest that infants with AOP have gross deficits in respiratory control. It appears, however, that the early (and frequent) occurrence of hypoxemia during apnea in preterm infants is related to their low expiratory lung volume, which falls even further during apnea, while the accompanying bradycardia results from this combination of apnea and hypoxemia. Feeding is an important trigger for AOP. While hypoxemia during feeding is most likely related to an immature coordination between sucking, swallowing and breathing and potentially also to an immature laryngeal chemoreflex, hypoxemia after feeding may be caused by diaphragmatic fatigue; gastro-esophageal reflux only rarely plays a role. The time course of AOP, i.e., its increased occurrence during the second and third rather than the first week of life, together with data from physiological studies, also suggests a role for diaphragmatic fatigue. Additional factors include upper airway obstruction, persistence of the fetal response to hypoxia, i.e., ventilatory depression, and the close proximity between the eupneic and apneic CO(2) thresholds in neonates. Observational data cannot provide definite answers on cause-and-effect issues but may provide a starting point for further studies into mechanisms involved in AOP and for the development of new therapeutic interventions. First, however, we need to better define how much AOP can be tolerated in an infant without endangering neurodevelopment.

Sleep is a biological mechanism essential to maintaining good health. A series of physiological changes takes place during sleep. From a ventilation point of view, during deep sleep, tidal volume increases, the inhalation and expiration phases become longer, and respiratory frequency slows, while the same volume/time ratio as in wakefulness is maintained. The concept of "sleep-related respiratory disorders" refers to a group of respiratory diseases that are aggravated during sleep. Some of these disorders are almost exclusively manifested during sleep, such as sleep apnea-hypopnea syndrome -undoubtedly the most frequent respiratory disease despite being underdiagnosed- and congenital central hypoventilation syndrome (also called Ondine's curse). However, this concept also encompasses other disorders that occur during the daytime since they worsen while patients are asleep, as seen in many obstructive or restrictive pulmonary diseases. Sleep disorders can be a manifestation of underlying diseases, some of which are highly prevalent such as obesity and gastroesophageal reflux. Likewise, abnormal sleep cycles may be a cause or a result of cognitive disorders and disturbances in children's learning processes.

Melatonin is used in many countries to improve sleep disorders. Melatonin is a hormone produced by the pineal gland and enterochromaffin cells which control sleep and gastrointestinal motility. Low levels of melatonin lead to gastroesophageal reflux disease (GERD). Most of patients with GERD have a sleep disorder. So, low melatonin levels is the main cause of insomnia. Beyond this, it has an inhibitory action on gastric acid secretion and seems to control the lower esophageal sphincter. Proton pump inhibitors (PPIs) are a group of drugs whose main action is a pronounced and long-lasting reduction of gastric acid production. They are the most potent inhibitors of acid secretion available today. Omeprazole (one of the PPIs) and melatonin have similarities in their chemical structures. Therefore, we could consider omeprazole as a rough copy of melatonin. In this paper, we compare the advantages and disadvantages of the clinical use of melatonin and PPIs.

Idiopathic pulmonary fibrosis (IPF) is the most common interstitial lung disease. Despite progress made in understanding the pathophysiological mechanisms behind the development of the disease, its prognosis is poor. For this reason, any measure to improve the quality of life for these patients should be preferred. Some authors are interested in sleep disorders, and possible impact on quality of life. Patients with IPF have lowered scores of quality of life compared to those found in general population, with some correlation with the scores of sleep quality. There is a hyperfragmentation with many arousals and desaturation events. Some authors also report an apnea-hypopnea index higher in these patients, but these data are not found in all the studies. Correcting these obstructive phenomena may have a beneficial effect on survival, which would make systematic the sleep assessment in these patients. Finally, the relationship between IPF, gastroesophageal reflux and sleep apnea syndrome remains unclear.

Development of Pediatric Pulmonology as a speciality in India is steadily improving over past few decades. Present profile of Indian pediatric chest services include: asthma, recurrent infections, bronchiectasis, etc. It is expected to change and the emerging pulmonary illnesses include: human immunodeficiency virus (HIV infection) associated pulmonary illnesses, cystic fibrosis, primary ciliary dyskinesia, bronchopulmonary dysplasia, interstitial lung diseases, gastroesophageal reflux diseases, neuromuscular illnesses, sleep disorders, disorders due to malformations and opportunistic pulmonary infections. Respiratory infections constitute major load in pediatric outpatient services and are the leading cause of mortality in under-five children. To reduce morbidity and mortality due to respiratory tract infections, Indian Academy of Pediatrics (IAP) has developed Respiratory Tract Infection Group Education Module (RTIGEMS). After initial increase in prevalence of asthma, it seems to have stabilized now but going by the numbers, it will remain a major health problem in India. Diagnosis of pulmonary tuberculosis was always a challenge to pediatricians and with emergence of drug resistant tuberculosis, it is even more challenging. Presently few centers are providing specialized Pediatric pulmonology services in India. There is a need to develop more centers to enhance services including (a) assessment of pulmonary physiology by performing pulmonary function testing in all age groups, (b) improving diagnostic and therapeutic role of bronchoscopy and bronchoalveolar lavage, (c) sweat testing, (d) molecular diagnostics for various respiratory illnesses, and (e) utilizing advance imaging and minimally invasive technologies for diagnosis and treatment of respiratory illnesses. At present there is no degree course in Pediatric Pulmonology in India. Initially middle level pediatricians wanting to pursue their career in pediatric pulmonology should undergo training in existing centers. Trained persons should develop a network to collect data and answer relevant research questions.

Sleep disorder is a common medical problem. Sleep disorder has been associated with several diseases, including pulmonary disease, gastroesophageal reflux disease (GERD) and fibromyalgia. Interest in sleep phenomenology and gastrointestinal functioning has recently increased, because sleep disorder causes significant morbidity, as evidenced by the increased need for general medical and mental health treatment for emotional problems. A number of studies have found an association between sleep disorders and functional gastrointestinal (GI) disorders. Although arousal from sleep serves several protective roles, such as increase in the speed of esophageal clearance and in airway refluxes to prevent aspiration, awakening from sleep unfortunately induces impairment of sleep quality. Some investigations about the relationship between psychogenic factors and gut motility are controversial. In addition, reports of alterations in gut motility during sleep have also been contradictory. We have evaluated sleep disorder in functional dyspepsia (FD) patients using Pittsburgh Sleep Quality Index (PSQI) score. In our recent data, PSQI score of FD patients was significantly higher compared to that in healthy volunteers. Another study has reported that the distribution of subjects who thought that they got enough sleep was significantly lower for the FD/irritable bowel syndrome (IBS) subjects than for control subjects. Several studies have reported that anti-acid therapy and prokinetic agents are effective for certain FD patients. In addition, previous study has reported tricyclic antidepressants (TCA) drugs are effective for some FD patients. Finally, new drug, actiamide, a muscarinic antagonist and cholinesterase inhibitor, significantly improves Postprandial Distress Syndrome (PDS) symptoms. It might be critical issues for determination of precise mechanism for functional gastrointestinal disorders to clarify the relationship between gut motility and sleep disorders.

Dental sleep medicine is a rapidly growing field that is in close and direct interaction with sleep medicine and comprises many aspects of human health. As a result, dentists who encounter sleep health and sleep disorders may work with clinicians from many other disciplines and specialties. The main sleep and oral health issues that are covered in this review are obstructive sleep apnea, chronic mouth breathing, sleep-related gastroesophageal reflux, and sleep bruxism. In addition, edentulism and its impact on sleep disorders are discussed. Improving sleep quality and sleep characteristics, oral health, and oral function involves both pathophysiology and disease management. The multiple interactions between oral health and sleep underscore the need for an interdisciplinary clinical team to manage oral health-related sleep disorders that are commonly seen in dental practice.

There are many different types of sleep disorders. The majority of sleep-related breathing disorders can be attributed to sleep apnoea syndrome. Nocturnal choking sensation is a different symptom, for which we present two cases. Nocturnal choking sensation is a terrifying symptom for the patient and the diagnostic approach can be challenging. Aside from sleep choking syndrome, this symptom may appear with nocturnal laryngospasm, insular epilepsy and nocturnal gastro-oesophageal reflux. A thorough patient history and observation of the nocturnal event, sometimes supported by EEG findings, may provide the clue to the diagnosis. These kinds of nocturnal symptoms are best analyzed in a clinic specialized in both epilepsy and sleep disorders.
