Toxigenic mold activities produce metabolites that are either broad-spectrum antibiotics or mycotoxins that are cytotoxic. Indoor environmental exposure to these toxigenic molds leads to adverse health conditions with the main outcome measure of frequent neuroimmunologic and behavioral consequences. One of the immune system disorders found in patients presenting with toxigenic mold exposure is an abnormal natural killer cell activity. This paper presents an overview of the neurological significance of abnormal natural killer cell (NKC) activity in chronic toxigenic mold exposure. A comprehensive review of the literature was carried out to evaluate and assess the conditions under which the immune system could be dysfunctionally interfered with leading to abnormal NKC activity and the involvement of mycotoxins in these processes. The functions, mechanism, the factors that influence NKC activities, and the roles of mycotoxins in NKCs were cited wherever necessary. The major presentations are headache, general debilitating pains, nose bleeding, fevers with body temperatures up to 40 degrees C (104 degrees F), cough, memory loss, depression, mood swings, sleep disturbances, anxiety, chronic fatigue, vertigo/dizziness, and in some cases, seizures. Although sleep is commonly considered a restorative process that is important for the proper functioning of the immune system, it could be disturbed by mycotoxins. Most likely, mycotoxins exert some rigorous effects on the circadian rhythmic processes resulting in sleep deprivation to which an acute and transient increase in NKC activity is observed. Depression, psychological stress, tissue injuries, malignancies, carcinogenesis, chronic fatigue syndrome, and experimental allergic encephalomyelitis could be induced at very low physiological concentrations by mycotoxin-induced NKC activity. In the light of this review, it is concluded that chronic exposures to toxigenic mold could lead to abnormal NKC activity with a wide range of neurological consequences, some of which were headache, general debilitating pains, fever, cough, memory loss, depression, mood swings, sleep disturbances, anxiety, chronic fatigue, and seizures.

All currently available antihypertensive drugs can cause adverse drug reactions. Potential adverse drug reactions should already be taken into account when a new antihypertensive regimen is started. It is furthermore important to ask at follow-up visits specifically about common adverse reactions. The aims of this article are therefore to shortly summarise common and typical adverse drug reactions of antihypertensives. All antihypertensives may cause dizziness, hypotension, allergies, rashes, gastrointestinal complaints and dry mouth. Thiazide diuretics furthermore may cause electrolyte disturbances, dehydration and hyperuricemia, betablockers may cause bronchospasm, bradycardia, cold extremities and sleep disturbances and calcium antagonists may cause flushing, ankle oedema and gingival hyperplasia. Concerning potential lethal adverse drug reactions, it is important to know that ACE inhibitors and angiotensin receptor antagonists are contraindicated in all patients with a history of angioedema. However, angiotensin receptor antagonists are well-suited alternatives for patients with ACE inhibitor-induced cough or hypogeusia. Rare adverse drug reactions are commonly recognised only after drug approval based on spontaneous reporting. This demonstrates the importance of considering medications as potential causes of new complaints and symptoms and to reports such suspected adverse drug reactions to the national pharmacovigilance centres. Only the local or international accumulation of comparable spontaneous reports allows the drug regulation agencies to recognise new and unexpected adverse drug reactions early and to initiate appropriate measures.

Presence of nocturnal symptoms is related to asthma severity. Clinically stable asthmatic children, too, report frequent nocturnal symptoms and sleep disturbances. The study determined these parameters in stable, asthmatic children, in their home environment. This case-control, questionnaire-based study in 70 school-going children comprised 40 asthmatics (Group 1) and 30, age/gender matched, healthy children (Group 2). Parents maintained peak expiratory flow (PEF) and sleep diaries for one week. Group 1 had significantly lower mean morning (250.3 vs. 289.1 I/minute) and mean evening PEF values (261.7 vs. 291.3 I/minute). Group 1 (38.95%), reported frequent nocturnal symptoms like cough (36.90%), breathlessness (32.80%), wheeze (27.68%) and chest tightness (14.35%). Sleep disturbances, significant in Group 1 (38, 95% vs. 14.35%), included daytime sleepiness (24.60%), daytime tiredness (20.50%), difficulty in maintaining sleep (15.38%), early morning awakening (14.35%), struggle against sleep during daytime (12.30%), and involuntarily falling asleep (17.43%). On a scale of 1-6, Group 1 scored significant sleep disturbances/patient (3 vs. 0.8); lethargy/tiredness in morning (2.9 vs. 2.2), poorer sleep quality (4.7 vs. 5.4), less parents' satisfaction with child's sleep (4.5 vs. 5.5) and daytime fitness (4.1 vs. 5.3). Group 1, when exposed to environmental tobacco smoke (22, 55%), reported significant nocturnal symptoms (18/22, 81%) and reduced mean morning and evening PEF values (17/22, 77%). It is concluded that clinically stable, asthmatic children reported increased nocturnal symptoms, sleep disturbances and poorer sleep quality. Lack of awareness of asthma-sleep association and its clinical implications could lead to poor asthma control and impaired daytime activity.

Asthma is the most common chronic respiratory disease of children in the world. Serial studies in the world have showed an increased prevalence of bronchial asthma. In this study, the children younger than 12 years old referred to Jahrom hospital and clinic due to asthma were selected. We issued 100 questionnaires, according to International Study of Asthma and Allergies in Childhood (ISAAC) criteria and were completed by the physicians. The ratio of male to female was 1 to 9. The patients who were under the age of 4, 3 and 1 year were 82%, 60% and 15% respectively. Passive smoking was present in 56% of the patients, and 22% had pets at home like cat, dog or bird. Home dampness was present in 33%. Ninety percent of patients had used breast feeding during the first year of life. Seventy percent of patients had family history of asthma. Food allergy was present and could trigger asthma in 15%. The result of ISSAC questionnaire showed that during the last year wheezing was present in 10%, 6% had 1-3 attacks and 4% had 4-12 attacks. Sleep disturbance by wheezing had occurred in 5% but cough in 16%. Thirteen percent of patients had wheezing after exercise. In Jahrom town the climate is warm and dry. In this town asthma in children is more common among the children who are younger than 4 years old. The risk factor like smoking at home, pets and home dampness should be eliminated from their environment.

Insomnia is highly prevalent in patients with chronic disease including chronic heart failure (CHF) and is a significant contributing factor to fatigue and poor quality of life. The pathophysiology of CHF often leads to fatigue, due to nocturnal symptoms causing sleep disruption, including cough, orthopnea, paroxysmal nocturnal dyspnea, and nocturia. Inadequate cardiac function may lead to hypoxemia or poor perfusion of the cerebrum, skeletal muscle, or visceral body organs, which result in organ dysfunction or failure and may contribute to fatigue. Sleep disturbances negatively affect all dimensions of quality of life and is related to increased risk of comorbidities, including depression. This article reviews insomnia in CHF, cardiac medication side-effects related to sleep disturbances, and treatment options.

In adults, several extra-digestive manifestations (cough, asthma, angina-like chest pain, ENT symptoms, dental erosions and even sleep disturbances) may be due to gastro-oesophageal reflux disease (GORD). In some cases, symptoms are triggered by an oesophageal reflex vagally mediated, while other symptoms are mainly related to the irritant effect of the refluxed material. The link with GORD is often difficult to establish because of the lack of typical digestive symptoms of GORD and of erosive oesophagitis in most of the cases. An empirical trial of double dose PPI therapy for 2 to 3 months can be done as the initial step in the diagnosis and treatment while oesophageal 24-hour pH monitoring is recommended by others to establish a temporal relationship between symptoms and reflux events. The optimal management algorithm remains to be determined. In some case, oesophageal luminal impedance monitoring could be useful to demonstrate a link between symptoms and a non-acid GORD. Traditionally, management of extra-oesophageal GORD manifestations relies on prolonged high doses of PPIs but the symptomatic efficacy of such treatment has been discussed recently. In case of adequate response, treatment can be tapered down to determine the minimal required maintenance dose. Anti-reflux surgery could be an alternative in some cases.

Common medical problems are often associated with abnormalities of sleep. Patients with chronic medical disorders often have fewer hours of sleep and less restorative sleep compared to healthy individuals, and this poor sleep may worsen the subjective symptoms of the disorder. Individuals with lung disease often have disturbed sleep related to oxygen desaturations, coughing, or dyspnea. Both obstructive lung disease and restrictive lung diseases are associated with poor quality sleep. Awakenings from sleep are common in untreated or undertreated asthma, and cause sleep disruption. Gastroesophageal reflux is a major cause of disrupted sleep due to awakenings from heartburn, dyspepsia, acid brash, coughing, or choking. Patients with chronic renal disease commonly have sleep complaints often due to insomnia, insufficient sleep, sleep apnea, or restless legs syndrome. Complaints related to sleep are very common in patients with fibromyalgia and other causes of chronic pain. Sleep disruption increases the sensation of pain and decreases quality of life. Patients with infectious diseases, including acute viral illnesses, HIV-related disease, and Lyme disease, may have significant problems with insomnia and hypersomnolence. Women with menopause have from insomnia, sleep-disordered breathing, restless legs syndrome, or fibromyalgia. Patients with cancer or receiving cancer therapy are often bothered by insomnia or other sleep disturbances that affect quality of life and daytime energy. The objective of this article is to review frequently encountered medical conditions and examine their impact on sleep, and to review frequent sleep-related problems associated with these common medical conditions.

The aim of this cross-sectional study was to compare the prevalence of asthma and its symptoms in children aged 6-7 years and 13-14 years in an urban (Amman city) area and among Bedouins in northern Jordan. The number of students included in both studied groups was 9108. This study is part of the International Study of Asthma and Allergies in Childhood (ISAAC), phase III. The response rate was 84% for urban schoolchildren compared with 68% among Bedouin schoolchildren. There was no statistical significance in prevalence of asthma diagnosed by a physician between the Amman city group and Bedouins (8.8% versus 9.5%). Wheeze induced by exercise and night cough was significantly common in schoolchildren aged 13-14 years compared with primary schoolchildren (18.5 and 25.3% versus 11.1 and 22.6%; p < 0.001). Wheezing ever and sleep disturbances were significantly more common in male subjects (27.5%, p < 0.01, and 12.2%, p < 0.001, respectively). Primary schoolchildren aged 6-7 years had significant wheezing ever (27.2%) compared with older children (25.1%; p < 0.05). Bedouin children had significant exercise-induced wheeze (16.4%) compared with children in Amman city (13.1%, p < 0.001), but the latter had significant prevalence of night cough (25%) compared with the Bedouin group (22.6%; p < 0.01). In conclusion, this study shows that asthma is moderately common in Jordan. There was no difference in prevalence of asthma diagnosed by a physician between an urbanized region and Bedouins having low socioeconomic status. Asthma was common in male children, which is similar to other reports elsewhere. There is a twofold increase in the prevalence of asthma in Jordan in the last 10 years.

Cystic fibrosis (CF) has been transformed from a fatal diagnosis in infancy to a chronic disease of children and young adults. Symptom patterns and disease burden in CF may be shifting to reflect the relatively healthier, older population with the disease. Self-management of symptoms is a hallmark of chronic illness, and yet we do not have a good understanding of how CF patients monitor or manage their symptoms. Children and adults were recruited through clinics in three Canadian provinces. Questionnaires with open-ended and close-ended questions in English and French, designed to assess the frequency, severity, and self-management of pain, breathlessness, and cough, were mailed to all the eligible participants. One hundred twenty-three respondents completed the survey, for a response rate of 64%. Eighty-four percent (103 of 123) of participants reported having pain. They reported an average of 2.1 locations of pain, with headache and abdominal pain most frequently described. Sixty-four percent (76 of 123) of participants reported having breathlessness, and 83% (99 of 123) of participants reported experiencing cough. Sixty-three percent (62 of 99) of participants with cough reported that cough always or sometimes interfered with their sleep. A variety of pharmacological and nonpharmacological treatments were used to manage symptoms. Pain and dyspnea are more common than suspected and a wide variety of pharmacological and nonpharmacological measures are used to treat symptoms. Cough is difficult to assess, but disturbed sleep may be an indicator of cough severity and an important symptom to consider when evaluating the overall burden of illness in those with CF.

Chronic cough is common in the paediatric population, yet the true prevalence of this condition remains difficult to define. Protracted bacterial bronchitis (PBB) is a disease caused by the chronic infection of the conducting airways. In many children the condition appears to be secondary to impaired mucociliary clearance that creates a niche for bacteria to become established, probably in the form of biofilms. In others, immunodeficiencies, which may be subtle, appear to be a factor. PBB causes persistent coughing and disturbed sleep, and affects exercise tolerance, causing significant levels of morbidity. PBB has remained largely unrecognised and is often misdiagnosed as asthma.
