RESUMO
The clinical and economic burden of hypertension is high and continues to increase globally. Uncontrolled hypertension has severe but avoidable long-term consequences, including cardiovascular diseases, which are among the most burdensome and most preventable conditions in Europe. Yet, despite clear guidelines on screening, diagnosis and management of hypertension, a large proportion of patients remain undiagnosed or undertreated. Low adherence and persistence are common, exacerbating the issue of poor blood pressure (BP) control. Although current guidelines provide clear direction, implementation is hampered by barriers at the patient-, physician- and healthcare system levels. Underestimation of the impact of uncontrolled hypertension and limited health literacy lead to low adherence and persistence among patients, treatment inertia among physicians and a lack of decisive healthcare system action. Many options to improve BP control are available or under investigation. Patients would benefit from targeted health education, improved BP measurement, individualized treatment or simplified treatment regimens through single-pill combinations. For physicians, increasing awareness of the burden of hypertension, as well as offering training on monitoring and optimal management and provision of the necessary time to collaboratively engage with patients would be useful. Healthcare systems should establish nationwide strategies for hypertension screening and management. Furthermore, there is an unmet need to implement more comprehensive BP measurements to optimize management. In conclusion, an integrative, patient-focused, multimodal multidisciplinary approach to the management of hypertension by clinicians, payers and policymakers, involving patients, is required to achieve long-term improvements in population health and cost-efficiency for healthcare systems.

Spontaneous splenic rupture is an uncommon complication of acute pancreatitis. This report describes the case of a 60-year-old man with acute pancreatitis complicated by splenic rupture. The patient was admitted to the emergency department with pain in the upper abdomen that had been present for 2 days. He was diagnosed with acute pancreatitis of alcoholic etiology. The patient was admitted to the hospital for two recurrent episodes in the last 4 months of acute pancreatitis of alcoholic etiology. Magnetic resonance imaging of the abdomen revealed a suspicious area of necrosis. Seventy-two hours after admission, the patient had significant improvement in symptoms and the inflammation markers rapidly decreased. However, he showed clinical worsening on the seventh day of hospitalization, with increasing abdominal distension and reduced hemoglobin levels. A CT angiography showed a large amount of free fluid in the abdominal cavity, along with a large splenic hematoma. The patient subsequently underwent laparotomy, which showed hemoperitoneum due to rupture of the splenic parenchyma. A splenectomy was performed with resection of the pancreatic tail.

Sleep related breathing disorders include central sleep apnea (CSA), obstructive sleep apnea (OSA), sleep-related hypoventilation, and sleep-related hypoxia. These disorders are frequent and growing in clinical relevance. The related chapter of the S3 guideline "Non-restorative sleep/Sleep disorders", published by the German Sleep Society (DGSM), has recently been updated in November 2016. Epidemiology, diagnostics, therapeutic procedures, and classification of sleep related disorders have been revised. Concerning epidemiology, a considerably higher mortality rate among pregnant women with OSA has been emphasized. With regards to diagnostics, the authors point out that respiratory polygraphy may be sufficient in diagnosing OSA, if a typical clinical condition is given. For CSA, recommendations were changed to diagnose CSA with low apnea rates present. Significant changes for treating CSA in patients with left ventricular dysfunction have been introduced. In addition, there is now to be differentiated between sleep-related hypoventilation and sleep-related hypoxaemia. Obesity hypoventilation syndrome is discussed in more detail. This article sums up and comments on the published changes.

In view of the high prevalence and the relevant impairment of patients with obstructive sleep apnoea syndrome (OSAS) lots of methods are offered which promise definitive cures for or relevant improvement of OSAS. This report summarises the efficacy of alternative treatment options in OSAS. An interdisciplinary European Respiratory Society task force evaluated the scientific literature according to the standards of evidence-based medicine. Evidence supports the use of mandibular advancement devices in mild to moderate OSAS. Maxillomandibular osteotomy seems to be as efficient as continuous positive airway pressure (CPAP) in patients who refuse conservative treatment. Distraction osteogenesis is usefully applied in congenital micrognathia or midface hypoplasia. There is a trend towards improvment after weight reduction. Positional therapy is clearly inferior to CPAP and long-term compliance is poor. Drugs, nasal dilators and apnoea triggered muscle stimulation cannot be recommended as effective treatments of OSAS at the moment. Nasal surgery, radiofrequency tonsil reduction, tongue base surgery, uvulopalatal flap, laser midline glossectomy, tongue suspension and genioglossus advancement cannot be recommended as single interventions. Uvulopalatopharyngoplasty, pillar implants and hyoid suspension should only be considered in selected patients and potential benefits should be weighed against the risk of long-term side-effects. Multilevel surgery is only a salvage procedure for OSA patients.

Central sleep apnea (CSA) is characterized by a lack of drive to inspire for at least 10 sec. In the CSA-syndrome accompanying arousals and desaturations of the arterial blood cause sleep disturbances and sympathetic nerve activations which lead to excessive daytime sleepiness and increase the risk for cardiovascular morbidity. There are six manifestations of CSA: a rare primary or idiopathic form, often in hypocapnic patients with an increased hypercapnic ventilatory drive; Cheyne-Stokes respiration, characterised by periodic CSA and a crescendo/decrescendo breathing pattern, often in patients with severe cardiac or neurological diseases; high altitude-induced periodic breathing (above 4000 m), CSA due to medical or neurological conditions; CSA due to drug or substance use; and primary sleep apnea of infancy. Besides the consequent treatment of the underlying medical conditions therapeutic options include the use of drugs, e. g. acetacolamide or oxygen, as well as non-invasive ventilation, e. g. continuous positive airway pressure (CPAP) or adaptive servo-ventilation.

Many patients with the obstructive sleep apnea syndrome (OSAS) look for alternative conservative or surgical therapies to avoid to be treated with continuous positive airway pressure. In view of the high prevalence and the relevant impairment of the patients lots of methods are offered which promise definitive cure or relevant improvement of OSAS. The working group "Apnea" in the German Society of Sleep Medicine and Research established a task force to evaluate the scientific literature on non-CPAP therapies in the treatment of OSAS according to the standards of evidence-based medicine. This paper summarizes the results of the task force. The data were unsatisfactorily for most of the methods. Sufficient data were available for intraoral appliances (IOA) and the maxillomandibular osteotomy (MMO). IOA's can reduce mild to moderate respiratory disturbances, MMO are efficient in the short and long term but are performed only in special situations such as craniofacial dysmorphias. Weight reduction and body positioning cannot be recommended as a single treatment of OSAS. Most surgical procedures still lack sufficient data according to the criteria of evidence based medicine. Resections of muscular tissue within the soft palate have to be strictly avoided. But even success following gentle soft palate procedures is difficult to predict and often decreases after years. Results in other anatomical regions seem to be more stable over time. Today combined surgeries in the sense of multi-level surgery concepts are of increasing interest in the secondary treatment after failure of nasal ventilation therapy although more data from prospective controlled studies are needed. There is no evidence for any other treatment options.

Recent studies suggest an association of obstructive sleep apnoea (OSA) with cardiovascular risk factors, such as dyslipidaemia. The present study analyses the effects of OSA and its therapy on serum lipid concentrations in 470 OSA patients in a single centre study. Multivariate regression showed a significant association between the apnoea-hypopnoea index and high-density lipoprotein cholesterol (HDL-C) serum levels (n = 366), independent of age, sex, body mass index, diabetes and lipid lowering medication. There were no independent associations with total cholesterol, triglyceride and low-density lipoprotein cholesterol serum levels. During follow-up (6 months) with effective bilevel or continuous positive airway pressure therapy in 127 patients (lipoproteins: n = 86) without change in their lipid lowering therapy, the mean HDL-C serum level increased significantly by 5.8% from 46.9+/-15.8 to 49.6+/-15.3 mg x dL(-1) (mean+/-SD). An independent relationship was found between the change of apnoea-hypopnoea index and the change of high-density lipoprotein cholesterol or triglycerides, respectively. All patients with abnormal serum lipid/lipoprotein levels improved significantly under bilevel or continuous positive airway pressure therapy. This study demonstrates an influence of obstructive sleep apnoea and its therapy on high-density lipoprotein cholesterol levels.

Obstructive sleep apnoea syndrome (OSAS) is a common disorder in obesity. Leptin, an adipocyte-derived signalling factor, plays an important role in metabolic control. There is growing evidence that leptin regulation is altered in OSAS. Therefore, the aim of this study was to test the hypothesis that effective treatment will influence leptin levels in OSAS patients. Serum leptin levels were determined in 86 consecutive patients (aged 57.5 +/- 11.0 yrs) with polysomnographically verified OSAS. In addition, leptin levels were reassessed and treatment efficacy was evaluated by polysomnography after 6 months of therapy. Patients were treated with continuous or bilevel positive airway pressure, a mandibular advancement device or conservatively, depending on the clinical symptoms. Mean serum leptin levels did not change with treatment in the whole study group (7.3 +/- 5.0 versus 7.5 +/- 4.8 ng.mL-1), however, leptin levels decreased in effectively treated patients (8.5 +/- 5.0 versus 7.4 +/- 5.1 ng.mL-1) while they increased in ineffectively treated patients (5.0 +/- 4.0 versus 7.7 +/- 4.1 ng.mL-1). Furthermore, not only was there a significant and independent correlation between the change in leptin levels with treatment and the change in body mass index, but also with the change in apnoea/hypopnoea index. Effective treatment of sleep-disordered breathing may have significant effects on leptin levels in obstructive sleep apnoea syndrome patients. Changes in leptin levels are related to changes in apnoea/hypopnoea index in obstructive sleep apnoea syndrome patients.

In obstructive sleep apnoea syndrome (OSAS), prosthetic mandibular advancement devices (MAD) seem to be a promising treatment alternative to conventional continuous positive airway pressure therapy. Unfortunately, while they are effective in some patients, they are ineffective in others or may even worsen OSAS. At present, it is not known whether predictors can be defined which allow for estimation of the potential effect of oral appliances on the severity of OSAS. Clinical and polysomnographical efficacy of a MAD was evaluated in 15 patients with OSAS. In addition, ultrafast magnetic resonance imaging (MRI) of the pharynx was performed in 13 of these patients at rest during transnasal shallow respiration and during performance of the Muller manoeuvre, both with and without the MAD, and the site of closure was determined. The MAD reduced the mean apnoea/hypopnoea index (AHI) from 19.8+/-14.5 to 7.2+/-7.4 x h(-1). Seven subjects (53.8%) had at least a 50% reduction in AHI to a value <10 x h(-1) with the MAD, whereas the MAD was ineffective in six patients. Five of the seven treatment responders had no significant pharyngeal obstruction during the manoeuvre with the device, while all of them had pharyngeal obstruction when not equipped with the device. Four of the six patients with treatment failure had a single velopharyngeal obstruction and two a combined obstruction of the velo- and glossopharynx during the Muller manoeuvre while wearing the device. The results of this study suggest that airway patency during the Muller manoeuvre while wearing a mandibular advancement device may be predictive of the success of obstructive sleep apnoea syndrome treatment with a mandibular advancement device.

BACKGROUND: Nasal continuous positive airway pressure (CPAP) is a well-established, widely used and effective treatment of obstructive sleep apnea syndrome (OSAS). Unfortunately, side effects are frequent during CPAP treatment. OBJECTIVES: Little is known about the effects of CPAP on infectious complications in patients with OSAS. METHODS: We retrospectively analyzed the kinds and rate of infections of the upper airway in 246 consecutive patients (mean age, 59.7 years) with polysomnographically verified OSAS using CPAP with or without a heated humidifier and compared them with OSAS patients who received non-CPAP therapy. RESULTS: Of the 246 patients, 40 received conservative therapy and 206 CPAP treatment, 36 of them with a heated humidifier. The mean follow-up period of the study group was 165.4 +/- 92.1 weeks and did not differ between the three groups. Infectious diseases were frequent in all three groups, but patients using CPAP without humidifier suffered from upper airway infections significantly more frequently than controls (42.9 vs. 25%; p < 0.05), and more patients on CPAP therapy with humidifier than controls (22.2 vs. 2.5%; p < 0.01) reported an increased rate of upper airway infections since initiation of CPAP therapy or diagnosis of OSAS. Especially patients using a hot water bath humidifier who cleaned their devices inadequately had significantly more upper airway infections since diagnosis (57.1 vs. 20%; p < 0.05) or during the past 6 months (52.4 vs. 13.3%; p < 0.05) than patients who regularly cleaned CPAP machines, humidifiers and ventilatory circuits. CONCLUSIONS: Our results suggest that patients using CPAP therapy either with or without heated humidity seem to be at an increased risk of upper airway infections compared to conservatively treated patients.

Background: The measurement of impedance permits reliable detection of obstructive apneas, hypopneas and upper airways resistance syndrome.Objective: To establish whether impedance-controlled self-adjusting positive airway pressure therapy (APAP(FOT)) is equally as good as constant continuous positive airway pressure (CPAP) in the treatment of sleep apnea syndrome (OSAS).Methods: Twenty men and five women with OSAS (age 52.8+/-9.0 years, body mass index (BMI) 31.4+/-5.0 kg/m(2), AHI 32.2+/-18.1/h (mean+/-SD)) underwent baseline polysomnography, manual CPAP titration and two nights of treatment, one with APAP(FOT), one with constant CPAP.Results: With both modes, a significant reduction in respiratory disturbances was seen (apnea/hypopnea index (AHI) baseline 32.2+/-18.1/h, constant CPAP 6.6+/-8.7, APAP(FOT) 5.5+/-3.8/h, P<0.001 baseline vs. each treatment mode). Under APAP(FOT), the sleep profile was normalized (S3/4 baseline 16.3+/-13.9% total sleep time (TST), APAP(FOT) 21.6+/-10.9% TST, P<0.05, rapid eye movement (REM) 14.2+/-6.7% TST vs. 20.3+/-7.3% TST, P<0.01), while with constant CPAP, a tendency towards improvement was found. The mean treatment pressure with APAP(FOT) was significantly lower than the constant CPAP (5.7+/-2.1 vs. 8.3+/-1.6 mbar, P<0.001).Conclusion: We conclude that APAP(FOT) is at least as effective as constant CPAP in normalizing sleep and breathing in OSAS.
RESUMO
BACKGROUND: Clinical observations have linked sleep-disordered breathing to cardiovascular morbidity and mortality, and especially to coronary artery disease. HYPOTHESIS: The study was undertaken to determine the prevalence of sleep-disordered breathing in consecutive patients referred for angina evaluation, and analyzed the parameters influencing the severity of sleep-disordered breathing. METHODS: In all, 68 consecutive patients (53 men, 15 women, aged 63.4 +/- 10.0 years) referred for angina evaluation were studied. Coronary angiography, selective left ventriculography, and a polygraphic study with a validated six-channel monitoring device were performed. Full-night polysomnography was used to reevaluate patients with an apnea/hypopnea index > or = 10/h. RESULTS: Sleep-disordered breathing as defined by an apnea/hypopnea index > or = 10/h was found in 30.9% of patients; its prevalence was not increased in patients with and without coronary artery disease (26.5 vs. 42.1%). Multiple stepwise linear regression analysis revealed that the severity of sleep-disordered breathing was significantly and independently associated with left ventricular ejection fraction (r = -0.38; p = 0.002), but not with age, body mass index, gender, diabetes mellitus, hypertension, hyperuricemia, hypercholesterolemia, smoking habits, or coronary artery disease. In this group of patients, multiple logistic regression analysis could not demonstrate sleep-disordered breathing to be an independent predictor of coronary artery disease. CONCLUSIONS: Sleep-disordered breathing is common in patients referred for angina evaluation. The degree of sleep-disordered breathing is mainly determined by the extent of left ventricular dysfunction.
