We report a 36 years male, admitted to the hospital for progressive respiratory failure. Chest X ray and CT scan were normal. On admission, a severe bradycardia and slow intellectual activity were noted. Serum thyroid function tests showed a TSH over 150 microU/ml and T3 of 75 ng/ml. Thyroid substitution therapy was associated with a progressive improvement of respiratory function. Diaphragmatic dysfunction, central hypoventilation, airway obstruction, sleep apnea and pleural effusion have been previously reported in patients with hypothyroidism. Therefore, we recommend to measure TSH in patients with unexplained respiratory failure.

The sleep apnea syndrome (SAS) and hypothyroidism have several common signs. This similarity creates a significant risk of undiagnosed hypothyroidism during the SAS. We studied the interest of thyroid function testing at patients suspected of having SAS. 201 consecutive patients, having a suspicion of SAS without history of hypothyroidism, underwent polysomnography (PSG) and biochemical thyroid testing. 91 patients (47%) had a SAS. Three patients among them (1.5% of patients undergoing PSG or 3.3% of those having a SAS) had previously undiagnosed hypothyroidism. These three patients have been treated by thyroxine. After euthyroidism was obtained by the treatment, SAS disappeared in 2 patients. The prevalence of the hypothyroidism in patients suspected of having SAS is not different from the one in the general population. However it is greater in patients with SAS. So we can conclude that biochemical screening for hypothyroidism is indicated only in case of proven SAS, in order to distinguish between a primary and a secondary origin.

Obstructive sleep apnoea poses a significant health hazard that is associated with leading causes of mortality and morbidity. Nasal continuous positive airway pressure is the primary treatment modality, with surgical treatments as alternatives. Oral appliances and pharmacological therapy remain adjunctive modalities. Non-specific treatments include weight loss, postural therapy and behavioural measures. Pharmacotherapy goals include the reduction of risk factors for sleep apnoea; correction of underlying predisposing metabolic diseases, such as hypothyroidism or acromegaly; treatment of associated symptoms, including excessive daytime sleepiness; and prevention of apnoeas/hypopnoeas. This paper reviews data supporting the treatment of sleep apnoea with various pharmacological agents, including intranasal corticosteroids, decongestant sprays, nicotine therapy, opiate antagonists, methylxanthine derivatives, oestrogen and progesterone, testosterone, thyroid hormone, growth hormone therapy for acromegaly, beta-blockers, alpha-adrenergic agonists, angiotensin-converting enzyme inhibitors, glutamate antagonists, acetazolamide, selective serotonin re-uptake inhibitors, tricyclic antidepressants, physostigmine, modafinil and TNF-alpha antagonists, in addition to supplemental oxygen, and carbon dioxide inhalation. Some of these drugs have received very little testing and are the subject of few research articles.

A number of predisposing factors (obesity, nasal obstruction, adenoidal hypertrophy, macroglossia, etc) have been related to obstructive sleep apnea syndrome (OSAS). In addition hypothyroidism and large goitres have been reported to be associated to OSAS, but this association has not been adequately studied. We describe an obese patient with euthyroid goitre associated with OSAS. The patient showed a body mass index (BMI) of 47 and a large neck with a circumference of 60 cm. The flow-volume curve demonstrated an expiratory plateau suggesting an intrathoracic upper airway obstruction. Arterial blood gas analysis results were: pH 7.39; PCO2 54.2 mmHg; P O2 47 mmHg. Nocturnal polisomnography showed an apnea/hypopnea index (AHI) of 31 episodes/hour. Upper airway collapse was overcome by a nasal continuous positive airway pressure (nCPAP) of 14 cmH2O. Weight loss obtained by a hypocaloric diet was not accompanied by any OSAS improvement. After thyroidectomy, a nCPAP of 4 cmH2O was sufficient to prevent upper airway closure. Discontinuation of nCPAP treatment for 4 consecutive nights did not determine worsening of sleep apnea symptoms, nor a worsening of overnight oxymetry. A new polysomnography carried out after 4 nights off nCPAP showed an AHI of 33 episodes/hour. OSAS should be suspected in patients with large goitres. Decisions regarding discontinuation of nCPAP treatment after thyroidectomy should be based on polisomnographic results.

A significant number of patients with obstructive sleep apnea neither tolerate positive airway pressure (PAP) therapy nor achieve successful outcomes from either upper airway surgeries or use of an oral appliance. The purpose of this paper, therefore, was to systematically evaluate available peer-reviewed data on the effectiveness of adjunctive medical therapies and summarize findings from these studies. A review from 1985 to 2005 of the English literature reveals several practical findings. Weight loss has additional health benefits and should be routinely recommended to most overweight patients. Presently, there are no widely effective pharmacotherapies for individuals with sleep apnea, with the important exceptions of individuals with hypothyroidism or with acromegaly. Treating the underlying medical condition can have pronounced effects on the apnea/hypopnea index. Stimulant therapy leads to a small but statistically significant improvement in objective sleepiness. Nonetheless, residual sleepiness remains a significant health concern. Supplemental oxygen and positional therapy may benefit subsets of patients, but whether these therapies reduce morbidities as PAP therapy does will require rigorous randomized trials. PAP therapy has set the bar high for successful treatment of sleep apnea and its associated morbidities. Nonetheless, we should strive towards the development of universally effective pharmacotherapies for sleep apnea. To accomplish this, we require a greater knowledge of the neurochemical mechanisms underlying sleep apnea, and we must use this infrastructure of knowledge to design well-controlled, adequately powered studies that examine, not only effects on the apnea/hypopnea index, but also the effects of pharmacotherapies on all health related outcomes shown beneficial with PAP therapy.

The relation between snoring and obstructive sleep apnea as well as hypothyroidism is the object of interest of many authors. The respiratory disturbances during sleep are often observed in patients suffering from hypothyroidism. The relation of snoring to overweight in those patients has not been taken into account. The aim of the study was to evaluate the relations between hypothyroidism and quantitative and qualitative respiratory disturbances during sleep. Additional aim was to establish the relations of sleep apnea syndrome, snoring, hypothyroidism and overweight. The subjects included 15 patients (11 females and 4 males) aged from 28 to 73 (mean 50.3) suffering from hypothyroidism. All of them underwent thyroid testing before and after the hormonal treatment. TSH and fT4 concentrations were determined. At the same time the sleep assessment (PolyMESAM) was performed twice. Data were obtained from sleep studies and questionnaires (Epworth sleepiness scale). After the thyroid hormones stabilization significant decrease of snoring severity was observed. On the contrary, the respiratory disturbance index (RDI), desaturation index (DI), the lowest saturation (LSAT) did not change significantly, however, the Epworth scale score showed significant improvement. The correlations showed the strong relation between loud snoring and TSH (r=0.73, p<0.01) and fT4 (r=-0.66, p<0.003) concentrations before the treatment. The analysis showed no correlation between body mass (BMI) and snoring. The hormonal stabilization in patients suffering from hypothyroidism causes improvement in snoring severity. Based on our investigation the relationship between hypothyroidism and severity of snoring and excessive daytime somnolence was confirmed. It indicates a possible connection between hypothyroidism and upper airway resistance syndrome.

In current healthcare, transitional healthcare is a very important and timely issue. Thanks to the major advances made in medical care and technology, many children with childhood onset diseases and/or genetic syndromes survive to adulthood. These children are at risk of not being provided with adequate healthcare as they reach adulthood. Healthcare transition is an essential part of healthcare provision, referred to as the shift from one type of healthcare to another. In Maastricht, we developed a transition/out clinic led by a medical doctor specialized in persons with intellectual disability (ID), together with a clinical geneticist. We aim to coordinate healthcare issues based on guidelines if available. Also questions concerning living, daily activities, relations, sexuality, and sterilization can be discussed. The aging process of persons with ID has been a topic of interest in recent years. Little is known about the aging process of people with specific syndromes, except for persons with Down syndrome. We present some data of a recent questionnaire study in persons with Prader-Willi syndrome. In only 50% in persons with a clinical diagnosis genetic test results could be reported. The majority of persons were obese. Diabetes mellitus, hypertension, skin problems, sleep apnea, and hormonal problems like osteoporosis and hypothyroidism were common. Psychiatric problems were frequent, especially in the persons with uniparental disomy. Osteoporosis and sleep apnoea seem to be underestimated. Further longitudinal research is necessary for a better understanding of the aging process in PWS.

Anesthesia for patients with Steinert's syndrome (myotonic dystrophy, MD) is a challenge for the anaesthetist. MD is a multisystemic disease and the neuromuscular symptoms can be associated with sleep apnea, endocrine disorders (diabetes, hypogonadism, hypothyroidism), cardiac, gastroenteric or cognitive disorders (mental deficiency, attention disorders). The diagnosis is facilitated when one or more of these symptoms are associated with the neuromuscular symptoms; however, the latter are not always present at the onset, which makes the diagnosis of MD a difficult and often late one. The choice of drugs and the choice of anesthesia in these patients can be very challenging for many reasons. A myotonic crisis can be triggered by several factors including hypothermia, shivering and mechanical or electrical stimulation. These patients are very sensitive to the usual anesthetics such as hypnotics and paralyzing agents (both depolarizing and nondepolarizing). The following case report describes pathophysiological considerations and a technique for anaesthesia during thoracic surgery that has been able to assure hemodynamic peroperative stability, early extubation and prolonged respiratory autonomy in a patient affected by this genetic disorder.

Chronic headache is still a frequent problem in old age, affecting about 10% of all women and 5% of all men older than 70 years. The incidence of primary headache decreases with advancing age, while that of secondary headache increases. The clinical characteristics of migraine can also change with age; for example, vegetative symptoms are less prominent, and less intense migrainous pain localized predominantly in the neck is frequently reported. Migraine aura can also be experienced more frequently in isolation, without a headache. Hypnic headache is a rare primary headache syndrome that occurs almost exclusively in the elderly. Most of the secondary headache syndromes that occur more frequently in old age present clinically as tension-type headache. Examples of rather common reasons for secondary headache syndromes in the elderly are intracranial space-occupying lesions, ophthalmological problems and autoimmune diseases such as giant cell arteritis. Elderly patients are especially likely to have a number of illnesses at any one time for which they take various medications each day, so that headaches can also quite often be caused by their medication or by withdrawal of these. As a result of such multimorbidity the homeostasis is disturbed in such patients, leading to various conditions that can entail concomitant headaches (sleep apnoea syndrome, dialysis headache, headache attributed to arterial hypertension or hypothyroidism). Familiar facial neuralgias, such as trigeminal neuralgia or postherpetic neuralgia following manifest herpes zoster affecting the face, become markedly more frequent with age. In general, in the treatment of headaches in the elderly it is essential to pay careful attention to potential interactions with the multiple drugs needed because of other diseases; in addition, the comorbidities themselves have to be taken into account, especially depression, anxiety and cognitive impairment, necessitating multimodal, interdisciplinary therapy plans.

This review discusses headaches secondary to disorders of homeostasis, formerly known as "headaches associated with metabolic or systemic diseases." They include the headaches attributed to 1) hypoxia and/or hypercapnia (high altitude, diving, sleep apnea); 2) dialysis; 3) arterial hypertension; 4) hypothyroidism; 5) fasting; and 6) cardiac cephalalgia. For each headache type, we discuss the clinical features and diagnosis, as well as therapeutic strategies.
