Hydatid cyst is a parasitic disease which occurs in multiple locations. The pulmonary localisation is preferential and responsible for an important symptomatology, being the second localisation after the hepatic one, which in most cases evolves asymptomatically. We present the case of a 24-year-old patient, who is a non-smoker and has had exposure to respiratory allergens (cat hair and dog hair), and who was admitted to the Pneumology Hospital with the complaints of cough with mucopurulent sputum and minimal haemoptysis and mild fever (37.1°C). It was reported that 3–5 weeks before hospitalisation, the patient had presented with an episode of vomiting, in moderate amounts with a typical appearance, but in the current context of the Coronavirus Disease-2019 (COVID-19) pandemic, he had delayed his presentation to the hospital. On clinical evaluation, the patient presented with diminished right basal vesicular murmur with overlying crackling rales. Following the investigations, the postero-anterior pulmonary radiography describes, at the level of the right lung, a hydro-aerial image with an uncertain appearance of unspecified aetiology. In this context, a native chest tomography (CT) was performed, which revealed a cystic formation at the level of the middle lobe, with thin walls and a prolific membrane detached inside, which are suggestive aspects for a hydatid cyst. Subsequently, a surgical consultation was performed, which concluded the superinfection of the cyst by a secondary lung abscess and the need for lobectomy. The peculiarity of the case consists in the appearance of persistent symptomatology and complications in a young patient without comorbidities and risk factors, and the fact that an accurate diagnosis was delayed because of the patient’s delayed presentation in the hospital in the context of the COVID-19 pandemic.

Background Obstructive sleep apnea (OSA) is a highly prevalent disease with substantial public health burden. In most of the cases, there is a genetic predisposition to OSA. Serotonin/T-HydroxyTriptamine (5-HT) plays a key role in ventilatory stimulation, while the polymorphism of the serotonin transporter gene (STG) leads to alterations in serotonin level, making it important in OSA. Objective To examine whether the 5-HydroxyTriptamine and the genetic predisposition influence the incidence and evolution of OSA, we reviewed randomized, controlled trials and observational studies on the selected topic. The secondary objective was to determine the metabolic effects of the circulating serotonin in other tissues (liver, pancreas, gut, brown adipose tissue, and white adipose tissue) and its role in the development of obesity. Data Sources A systematic review of English articles was performed based on PubMed and the Cochrane Library databases. Search filters included randomized controlled trial, controlled clinical trial, random allocation, double-blind method, and case–control studies and used the following keywords: Brain Serotonin OR Serotonin Transporter Gene Polymorphism OR Peripheral 5-HydroxyTryptamine AND Obstructive Sleep Apnea OR Sleep Disorder Breathing OR brain serotonin AND OSA OR serotonin transporter gene OR Peripheral 5-Hydroxytryptamine AND Sleep. Study Eligibility Criteria The inclusion criteria for the current review were previous diagnosis of OSA, age above 18 years, and articles including quantitative data about serotonin transporter gene or peripheral serotonin. Language and time criteria were added – English articles published in the last 15 years. Studies that were not included were reviews and case reports. Study Appraisal and Synthesis Methods In order to study the serotonin function, a literature research was conducted in the databases Pubmed and Cochrane Library. The following search terms were used: serotonin, 5-hydroxytryptamine, serotonin transporter gene. A critical appraisal of the included studies was performed with the Newcastle-Ottawa scale (NOS) and Delphi list. Results The search yielded 1210 articles, from which 43 were included. The included studies suggest that the two polymorphisms of serotonin transporter gene (5HTT) – variable number of tandem repeats (VNTR) and linked polymorphic region (LPR) – are strong candidates in the pathogenesis of OSA. The allele 10 of 5HTTVNTR and the long/long (L/L) allele genotype were associated with a higher prevalence of OSA and the L allele with a higher apnea-hypopnea index and a longer time during sleep with oxygen desaturation. Limitations The main limitation of the present study consists of heterogeneity of the information. Being a less studied subject, randomized trials are not widely available and most data were obtained from case–control trials. Moreover, the included material indirectly approached the subject by demonstrating the effects of serotoninergic system over the metabolism, the connection between serotonin and obesity, factors which are implied in the pathogenesis of OSA. Conclusion and Implications of Key Findings The two polymorphisms of serotonin gene can be considered important factors in the diagnosis and management of OSA.

Obstructive sleep apnea (OSA) has become a major worldwide health concern and affects 2-4% of males and 1-2% females. In subjects diagnosed with mild or severe OSA, CPAP (Continuous Positive Airway Pressure) is highly efficacious in improving the specific quality of life and the cardiovascular outcome but adherence to treatment limits its overall effectiveness. Factors that influence the adherence to CPAP therapy include patients’ individual characteristics, disease severity, titration procedures, the presents of side effects and the psychosocial factors. The management of this pathology is multidimensional and is based on some interventions such as lifestyle modifications, physical training, oral appliance and educational, pharmacological, technological strategies. These measures are implemented to limit the adverse effects of CPAP therapy in order to maximize the CPAP usage and to obtain a decrease of symptomatology and an optimum quality of life in OSA patients.

Pulmonary tuberculosis (TB) still represents a chalenge for the healthcare systems, in the active but also in the chronic phase, when TB sequelae may appear. Anatomical changes and destruction of lung parenchyma lead to loss of pulmonary volumes. The patients with post TB sequelae are expresing dyspnea, chronic cough, muscle weakness and reduced daily activity. We present the case of a 58 years old patient, with post TB sequelae (2 episodes of relapses), presenting dyspnea, chronic fatigue and bronchiectatic syndrome. He was included in a 8 weeks multidiciplinary pulmonary rehabilitation program, which comprised exercise trainng, airway clearance techniques, education. The results of PR program were positives: decrease of dyspnea (one point in mMRC scale), improvement of exercise tolerance (58 m gain at 6MWT), improvement in life quality (SGRQ decrease with 5.2 points). In conclusion, pulmonary rehabilitation may be a useful therapy in the management of post tuberculosis sequelae.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fatal lung disease with a median survival rate of 2-4 years after diagnosis, occurring primarily in older adults. The diagnosis is suggested by histology or radiologic evidence of a usual interstitial pneumonia (UIP) pattern and exclusion of known cases of pulmonary fibrosis. There are some comorbidities associated with IPF such as pulmonary hypertension, emphysema, chronic obstructive pulmonary disease (COPD), asthma, lung cancer, cardiovascular disorders, gastroesophageal reflux disease (GERD), sleep disorders and psychiatric disturbances. The management of IPF focuses on the amelioration of symptoms, preserving lung function, improving health status, minimizing the adverse effects of therapy and improving survival. Pulmonary rehabilitation is suggested for IPF patients when adequate medical therapy controls poorly the disease progression and mental, physical or social consequences of the illness persist during daily life. Currently, there are only two approved available antifibrotic therapies, pirfenidone and nintedanib, capable to reduce disease progression and physical deterioration, but cure is elusive and improvements are hardly observed. In addition, there is a continuous need of non-drug therapy components which should be included in IPF patient management: education, psychosocial support, exercise training, nutrition, symptom management and palliative care, non-invasive ventilation and pulmonary transplant. These complementary therapies have been proven to improve dyspnea, exercise capacity, fatigue and quality of life. Key words: idiopathic pulmonary fibrosis, rehabilitation, quality of life, palliative care

Background: Despite efforts at treatment, obstructive sleep apnea (OSA) remains a major health problem, especially with increasing evidence showing an association with cardiovascular morbidity and mortality. The treatment of choice for OSA patients is Continuous Positive Airway Pressure (CPAP), which has been proven in randomized controlled trials to be an effective therapy for this condition. The impact of CPAP on the cardiovascular pathology associated with OSA remains, however, unclear. Although the effect of CPAP has been previously studied in relation to cardiovascular outcome, follow-up of the treatment impact on cardiovascular risk factors at one year of therapy is lacking in a Romanian population. Thus, we aimed to evaluate the one-year effect of CPAP therapy on lipid profile, inflammatory state, blood pressure and cardiac function, assessed by echocardiography, on a cohort of Romanian OSA patients. Methods: We enrolled 163 participants and recorded their baseline demographic and clinical characteristics with a follow-up after 12 months. Inflammatory and cardiovascular risk factors were assessed at baseline and follow up. Results: Our results show that CPAP therapy leads to attenuation of cardiovascular risk factors including echocardiographic parameters, while having no effect on inflammatory markers. Conclusion: Treatment of OSA with CPAP proved to have beneficial effects on some of the cardiovascular risk factors while others remained unchanged, raising new questions for research into the treatment and management of OSA patients.

Obstructive Sleep Apnea (OSA), characterized by airflow cessation (apnea) or reduction (hypopnea) due to repeated pharyngeal obstructions during sleep, causes frequent disruption of sleep and hypoxic events. The condition is linked to many adverse health related consequences, such as neurocognitive and cardiovascular disorders, and metabolic syndrome. OSA is a chronic condition requiring long-term treatment, so treatment using continuous positive airway pressure (CPAP) has become the gold standard in cases of moderate or severe OSA. However, its effectiveness is influenced by patients’ adherence. Surgery for OSA or treatment with oral appliances can be successful in selected patients, but for the majority, lifestyle changes such as exercise and dietary control may prove useful. However, exercise training remains under-utilized by many clinicians as an alternative treatment for OSA. Other interventions such as oral appliance (OA), upper way stimulation, and oropharyngeal exercises are used in OSA. Because the benefit of all these techniques is heterogeneous, the major challenge is to associate specific OSA therapies with the maximum efficacy and the best patient compliance.

Asthma is defined by The Initiative for Asthma (GINA 2018) as a heterogeneous disease, which include chronic airway inflammation and a history of respiratory symptoms. In the last decades asthma had a rise in prevalence, becoming one of the most frequent diagnosed diseases in the world. The main goals of asthma management are to achieve good symptom control, minimize the risks of exacerbations, decrease rescue medication intake, improve the quality of life by decreasing respiratory system inflammation and ameliorating the patient’s lung function. Beside effective medications, asthma continues to impair quality of life for most patients. Due to the difficulty of controlling symptoms and exacerbations, the need of developing complementary options of treatment is increasing in order to achieve an optimum control and a lower risk of acute episodes or fatal events. Pulmonary rehabilitation is suggested for asthma patients when adequate medical therapy poorly control the symptoms and mental, physical or social consequences of illness persist during the daily life. The following non-drug therapy components are included in the rehabilitation program: physical training, comprehensive smoking cessation program, comprehensive patient education, respiratory physiotherapy, psychosocial support and comprehensive nutritional counseling. These complementary therapies have been proven to improve muscle strength, exercise capacity and symptomatology. Also, it has been associated to fewer exacerbations and a lower use of rescue medication, leading to a better quality of life. Key words: asthma, quality of life, symptomatology, rehabilitation, physiotherapy

Non-Cystic Fibrosis Bronchiectasis (NCFB) are characterised by abnormal, permanently damaged and dilated bronchi due to the innapropiate clearence of various microorganisms and recurrent chronic infections.The diagnosis is suggested by the clinical presentation and is confirmed by multiple investigations. There are some comorbidities associated with bronhciectasis, such as chronic obstructive pulmonary disease (COPD), cardiovascular disorders, gastro-esophageal reflux disease (GERD), psychological illnesses, pulmonary hypertension, obstructive apnea syndrome(OSA). The condition has a substantial socioeconomic impact because it requests a multidisciplinary management and periods of exacerbations are common. The aims of the management of bronchiectasis are to reduce symptoms (such as sputum volume and purulence, cough and dyspnea), reduce the frequency and severity of exacerbations, preserve lung function and improve health-related quality of life. The multidisciplinary approach of bronchiectasis patients require along with the medical treatment, a specific plan of nonphamarcological strategies, including balneological intervention. There are a lot of techniques improving the airway clearence, such as: active cycle of breathing techniques (which include breathing control, thoracic expansion exercises, forced expiratory technique), oscilatting possitive expiratory pressure, autogenic drainage, gravity-assisted-positioning, modified postural drainage. Together with specific medication, these techniques can diminuate symptoms and improve the quality of life. Key words: NCFB, airway clearence, physiotherapy

The overlap syndrome (OS) is defined as a synergic relation between obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD). Patients with overlap syndrome present the clinical features of each disorder to a greater or a lesser extend depending on the predominant disease. We assessed the main differences between patients with OS and patients with OSA and we highlight the importance of nocturnal hypoxemia on clinical status and management of the patients with overlap syndrome, in order to simplify OSA screening tests in patients with COPD. The study population included 62 selected patients divided in two groups: the first group � subjects diagnosed with OS and the second group - subjects with OSA, without the diagnostic of COPD. The majority of the patients were male, with a mean age of 55�9.84 years in the OSA group and 65.5�10.32 years in the OS group. The nocturnal hypoxemia was more important in the OS grup, with 276.83 minutes spent at a SpO2 below 90% versus 132.98 minutes in the OSA group. The mean AHI was 57.7�29.244 events/hour of sleep in the OS group and 50.7�26.01 events/hour of sleep in the OSA group. At the diagnosis, the mean daytime SpO2 was 90.9�3.59% in the OS group and 95.9�1.57 % in the OSA group. There were statistically significant differences between the two groups concerning age, AHI, Epworth Slepiness Scale, nocturnal desaturation, medium and minimum SpO2 during sleep, daytime SpO2 at the diagnosis and at 1-year follow-up, the presence of cardiovascular comorbidities such as pulmonary hypertension and heart failure. Our study showed that patients with COPD have OSA predictors that differ from those usually recognise in the general population. In OS patients, the most important parameter is the nocturnal hypoxemia. So, it is very useful that the clinicians be trained to include in the management of selected obese COPD patients, comprehensive sleep history, sleep hygiene and OSA screening because, in clinical practice, OSA is quite often underdiagnosed in these patients.

Introduction. Chronic Obstructive Pulmonary Disease (COPD) is a common, preventable and treatable disease. The pulmonary rehabilitation (PR) is a mutidisciplinary and comprehensive intervention in symptomatic patients with COPD. Objective. This review aims to synthesize evidence from available studies on the relative efficacies of different methods of rehabilitation therapies in patients with stable COPD. Material and Methods. A search was performed on the databases Pubmed, Embase, ResearchGate. Of the 410 articles retrieved from databases, only 20 met the inclusion criteria. Two reviewers independently reviewed selected eligible studies. Results. Rehabilitation is a multidisciplinary intervention in symptomatic patients with COPD, including speleotherapy, halotherapy, muscular training, soft tissue manual therapy and neuromuscular electrostimulation. All of the case-control studies using speleotherapy reported improved respiratory function to varying degrees and there were improvements in lung functional tests including forced vital capacity (FVC), forced expiratory volume in 1 second (FEV 1), oxygen saturation, partial pressure of oxygen in arterial blood, and partial pressure of carbon dioxide in arterial blood. In addition, halotherapy has been associated with relief of respiratory conditions such as COPD, asthma and cystic fibrosis by its bactericidal effect, improvement of immunity and rheological properties of secretions. Respiratory muscle training is a part of rehabilitation for COPD subjects. In patients who can not perform physical activity, neuromuscular electrostimulation (NMES) increased 6 minute walking distance and time to symptom limitation exercising at a submaximal intensity and reduced the severity of leg fatigue on completion of exercise testing. Conclusion. The management of COPD should include a multidisciplinary therapy, including rehabilitation therapies as an adjuvant to the medical treatment, especially because due to the high prevalence, mortality, and morbidity, COPD will be one of the biggest public health challenges in the next century.
