Abstract
The non-invasive management of clinically significant hemoptysis by bronchoscopy remains a therapeutic challenge. Various agents have been used endobronchially in order to control hemoptysis, such as cold saline, tranexamic acid, and epinephrine. This review summarizes all available data in that view, especially in resource limited settings, where more advanced means of controlling hemoptysis are not available.

Abstract
OBJECTIVE Obstructive Sleep Apnea (OSA) has been associated with both subclinical and accelerated atherosclerosis; however, it still remains unknown whether this association is unique or is mediated by the higher burden of co-existing cardio-metabolic disorders frequently seen in patients with OSA. PATIENTS AND METHODS A total of 40 subjects without clinically diagnosed cardiovascular disease (CVD) referred for polysomnography test were included in the study. Subjects with apnea/hypopnea index (AHI > 15/h) were classified as moderate/severe OSA. Subclinical changes in carotid atherosclerosis were assessed using mean carotid intima-media thickness (cIMT) and presence of atheromatic plaques on both carotid arteries. The measurement was performed using B-mode ultrasonogram. Framingham risk score was used in the approximation of cardiovascular risk. RESULTS The mean age of our cohort was 56.8 years, 70% (n = 28) of whom were males. Moderate/severe OSA was diagnosed in 21 subjects. Both groups were well matched in terms of clinical and demographic characteristics, and cardiovascular risk profile, as shown in their respective Framingham risk scores (10.4 ± 6.6 vs. 11.8 ± 8.8, p = NS). Patients with moderate/severe OSA had a higher mean AHI, 3% oxygen desaturation index, and lower minimum nocturnal oxygen saturation than controls. No significant differences were detected in terms of C-reactive protein levels. The two groups had similar cIMT (0.66 ± 0.17 vs. 0.75 ± 0.20 p = 0.33) and presence of atheromatic plaque (50% vs. 45%, p = 1.00). CONCLUSIONS Our study suggests that among patients with similar cardiovascular risk profile and free of overt CVD, the severity of newly diagnosed OSA was not correlated with increased inflammation or subclinical carotid atherosclerosis.

Abstract
OBJECTIVE Obstructive Sleep Apnoea Syndrome (OSAS) is a respiratory disorder characterized by recurrent airflow obstruction caused by total or partial collapse of the upper airway. OSAS is an established independent factor of cardiovascular risk together with other risk factors such as smoking and increased lipids. The aim of our study was to measure serum levels of aldosterone and renin in OSAS patients that did not suffer from arterial hypertension and compare them to matched healthy subjects in order to reveal the impact of chronic intermittent hypoxia on the renin-angiotensin-aldosterone system. PATIENTS AND METHODS The patients that enrolled in this study were 19 OSAS patients who had undergone overnight polysomnography and had an Apnoea Hypopnoea Index (AHI) greater than 10 events/hour. They were compared to 20 healthy non-OSAS closely matched controls. Serum aldosterone and direct renin concentration were measured by radioimmunoassay. RESULTS Aldosterone concentration follows a diurnal variation; therefore, all blood samples were obtained at the same time (6 AM). There were no significant differences in serum aldosterone levels between the two studied groups of OSAS patients and the healthy subjects group (140.6 pg/ml ± 25.2 vs. 133.2 pg/ml ± 18.5 with p = 0.223). Similar were the results for the renin levels (25.0 ± 6.9 vs. 24.9 ± 4.4 with p = 0.360). CONCLUSIONS Our study suggests that patients with OSAS, but without existing hypertension have aldosterone and renin levels similar to healthy subjects. According to our findings a direct connection between OSAS and the development of arterial hypertension may not be established via sympathetic system activation.

Abstract
We present the case of a 33-year-old male patient suffering from lymphocytic pleural effusion, as a result of pleural mesothelioma. Mesothelioma is a malignant tumor of the pleura that is mainly caused by chronic exposure to asbestos fibers and more than 40 years of exposure are needed to develop the disease. Early studies on the relationship of asbestos and mesothelioma were issued in the 1960s. Fibers migrate from the parenchyma of the lung to the visceral pleura. It is widely known that asbestos is an oncogenic factor which can cause damage to DNA. A chest x-ray may reveal pleural effusion with or without pleural thickening, whereas a chest CT may also reveal pleural thickening, uniform and/or lobular. Specific tests, such as immunohistochemical staining, are used in order to help differential diagnosis. Extrapleural pneumonectomy is used as a therapeutic option which involves removal of the lung as well as both the visceral and parietal pleura, the affected part of the pericardium and diaphragm. Surgery should be followed up by radiotherapy and chemotherapy. The surgery may lead to a mean survival rate of approximately 9-21 months. The case presented underlines that in the event of pleural effusion with a lymphocyte type physicians should consider the possibility of a pleural mesothelioma during differential diagnosis, even in relatively young patients.

Abstract
OBJECTIVES Obstructive sleep apnea syndrome (OSAS) is a common disorder defined by repeated episodes of airflow cessation (apneas)leading to arterial hypoxemia and sleep disruption. OSAS has been associated with increased morbidity, mortality and diminished quality of life so far. This cross-sectional study aimed to assess the impact of OSAS on patients' Quality of Life, as measured by the Medical Outcomes Study Short Form-36 (SF-36). PATIENTS AND METHODS Two hundred and forty five subjects referred to the sleep laboratory and underwent full polysomnography overnight. Prior to sleep study onset, we registered height and weight, medical history, smoking habit, drug consumption. Afterwards, each patient completed the SF-36. Eighty subjects not diagnosed with sleep apnea [apnea hypopnea index (AHI < 5)] were excluded. Therefore, 165 subjects (121 male and 44 female) remained. RESULTS AND CONCLUSIONS Statistical analysis revealed that in patients with respiratory disturbance index (RDI) ≥ 15, (n = 115), RDI was independently associated with lower performance in role limitations due to physical problems (p = 0.005). Additionally, RDI was the only factor associated with decreased vitality (p = 0.014) and mental health scores (p = 0.047). In the same patient subgroup, body mass index (BMI) and age were associated with poorer scores in physical functioning (p < 0.001 and p = 0.003, respectively). BMI was an independent clinical predictor of worse scores in bodily pain (p = 0.006) general health (p = 0.006), social functioning (p = 0.025) and role limitations due to emotional problems (p = 0.004).

Abstract
Infections remain a part of the natural course of cancer. During the course of their disease, patients with lung cancer frequently present with an infection that can ultimately be fatal. Pathogenesis of infectious syndromes is usually determined by the underlying disease, as well as, the iatrogenic manipulations that occur during its management. Hence, lung cancer infections include lower respiratory tract infections in the context of COPD, aspiration, obstruction and opportunistic infections due to immunosuppression. Moreover, treatment-related infectious syndromes including post operative pneumonia, febrile neutropenia and superimposed infection following radiation/chemotherapy toxicity is common. Importantly, diagnosis of infection in the febrile lung cancer patient is challenging and requires a high index of suspicion in order to distinguish from other causes of fever, including malignant disease and pulmonary embolism. Prompt initiation of treatment is pivotal to avoid increased mortality. Careful consideration of infection pathogenesis can predict most likely pathogens and guide antibiotic management, thus, ensuring most favourable outcome.

Abstract
We present a case of an idiopathic pulmonary artery aneurysm in an asymptomatic patient who was treated for an irrelevant medical condition. Pulmonary artery aneurysms (PAA) are quite rare and can either be congenital or acquired. Congenital aneurysms are usually associated with cardiac malformations leading to pulmonary hypertension. Acquired aneurysms can be idiopathic or associated with infections (tuberculosis, syphilis), trauma, pulmonary valvular stenosis, or collagen diseases. Pulmonary artery aneurysms are not common and an idiopathic pulmonary artery aneurysm is a rare finding that could be diagnosed incidentally.

Abstract
BACKGROUND AND AIM The phenotypic expression of COPD consists of pulmonary emphysema and chronic bronchitis. An imprecise phenotypic definition may result in inconsistencies among genetic studies regarding COPD pathogenesis. Endothelin-1 gene polymorphisms have been linked to increased susceptibility of COPD development. The present study examined the involvement of +138 insA/delA and G198T ET-1 polymorphisms with emphysematous and bronchitic COPD phenotypes. METHODS In order to narrow down the phenotypic choices to either COPD-associated pulmonary emphysema or chronic bronchitis, a DLCO < 60% predicted threshold was chosen as an indicator of severe emphysema. 116 COPD smokers and 74 non-related, non-COPD smokers were evaluated. RESULTS Statistical analysis showed that the 4A allele of the +138insA/delA SNP and the 4A:T haplotype were associated predominantly with a chronic bronchitis phenotype, whereas the TT genotype of the G198T SNP was found to be protective from emphysema development. CONCLUSIONS The presence of both the 4A and T allele seems to modify the final expression of COPD towards a chronic bronchitis phenotype, since the G:3A haplotype was associated with a predominantly emphysematous phenotype in our study.

Abstract
Pulmonary infection by Nocardia spp. has been recognized the last decades. Nocardia is an opportunistic pathogen in immunocompromised individuals; nevertheless, it has been recognized as an uncommon pathogen in immunocompetent patients. We report a case of pulmonary infection by Nocardia asteroides in an immunocompetent host who had a history of sulfate acid aspiration, followed by gastric tube interposition, reconstruction of the hypopharynx and gastric-hypopharyngial anastomosis.

Abstract
Gastroesophageal reflux disease (GERD) has been associated with a variety of pulmonary manifestations, but it is unclear if gastroesophageal reflux causes any abnormality in pulmonary function. Cardiopulmonary exercise test (CPET) is a specialized method that is used to evaluate respiratory function during exercise. The aim of this study was to reveal any abnormality of pulmonary function in patients with GERD and respiratory symptoms. We evaluated 34 patients with GERD (24 men and 10 women, aged 21-63) and extraesophageal respiratory symptoms (wheezing and/or cough) before therapy and after a 12-week treatment with double dose of omeprazole. No patient presented abnormal spirometry. CPET was performed in all the patients at baseline and after completion of the 12-week treatment. CPET parameters including VO(2) rest, VO(2) max, VCO(2) rest, VCO(2) max, O(2)-puls rest, O(2)-puls max, HR (heart rate) rest, HRmax, PETCO(2) rest, PETCO(2) max, and VE/VCO(2) slope were recorded pretreatment and posttreatment. Twenty-four patients (70.6%) had esophagitis (grade A-D), 16 patients had hiatal hernia (47.1%), and 13 patients (38.2%) tested positive for Helicobacter pylori. All of the patients completed the CPET. No one presented shortness of breath or respiratory symptoms. CPET parameters were within normal limits in all of the patients. Twenty-eight patients were reevaluated. No improvement in any CPET parameter posttreatment was observed despite remission of esophageal and extraesophageal respiratory symptoms in all patients. No statistically significant difference was observed pretreatment and posttreatment between the patients older and younger than 40 years, smokers and nonsmokers, Hp(+) and Hp(-) patients, and those with and without hiatal hernia and esophagitis. The patients with GERD and respiratory manifestations and normal spirometry present no pulmonary dysfunction during CPET. No alterations in CPET values posttreatment or differences in CPET values according to age, smoking, Hp status, presence of esophagitis, or hiatal hernia were observed.

Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide that may lead to impaired exercise tolerance. In this study we exhibit the relationship between two endothelin-1 (+134 3A/4A and G198T) SNPs involved in COPD and their association to impaired exercise tolerance. MATERIALS AND METHODS The study population consisted of 22 COPD smokers and 32 smoking controls which underwent pulmonary function tests to assess forced expiratory volume for 1 second (FEV1), forced vital capacity (FVC), as well as cardiopulmonary exercise testing. Single nucleotide polymorphism were isolated using Real-Time PCR. RESULTS The distribution of both genotypes (3A3A, 3A4A, 4A4A for the +134 3A/4A and GG, GT, TT for the G198T) did not different among patients and non-COPD smoking controls. Multivariate analysis showed that the 3A4A and GG genotypes in the COPD group were independently associated with better V'O2max values (Odd's Ratio (OR) = 12.5, 95% CI = -0.85-25.1, p = 0.049, and OR = 6.1, 95% CI = 0.83-11.4, p = 0.026, respectively). On the contrary analogous analysis in the non-COPD control group, showed that the 3A3A genotype was independently associated with increased V'O2/pulse (OR = 51.5, 95% CI = 17.2-85.7, p = 0.005) and the 3A4A genotype with increased DVE/DVCO2 value (OR = 3.8, 95% CI = -0.27-7.9, p = 0.054). DISCUSSION Our results show that endothelin-1 gene is implicated in exercise performance in COPD patients and might play a role in adaptation of the cardiopulmonary system to exercise.

Abstract
Inhalation of metal dusts and fumes can induce a wide range of respiratory disorders, including granulomatosis, chemical pneumonitis and pulmonary interstitial disease. Laryngeal cancer is the most common cancer of the upper aerodigestive tract. We present a patient with occupational lung disease whose chest CT showed miliary nodular pattern, with concurrent laryngeal cancer who had been engaged in type printing for 22 years. Histology of the laryngeal lession showed squamous cell laryngeal cancer. Histology of the nodules showed a foreign body granulomatous response with several foreign body cells, most probably due to exposure to numerous inorganic (lanthanides, elements such us La, Ce, Nd, Sm, EU, Tb, Lu) and organic particles (such us acrylates, epoxy- and urethane-acrylates).

Abstract
Baker's asthma, like other forms of occupational asthma is probably the most serious manifestation of occupational allergy among bakery workers. It is caused by immunologic sensitization and subsequent allergic reactions in the airways to occupational specific airborne allergens. Skin Prick Tests (SPTs) play an important role in the diagnosis of baker's asthma and epidemiological field studies on frequencies of sensitization to flour. This paper presents a review of the available literature on prevalence of flours sensitization in bakery workers. Atopy and level of exposure appears to be a very strong determinant for sensitization to flour allergens. Prevention strategies and standard setting are discussed.

Abstract
BACKGROUND Exercise is known to be a powerful stimulus for the endocrine system. The hormonal response to exercise is dependent on several factors including the intensity, duration, mode of exercise (endurance versus resistance), and training status of the subject. The aim of the present study was to determine the steroid hormonal response (immediately after a race and 1 week later) to endurance exercise under the real conditions of the classic Athens marathon in a group of well-trained, middle-aged, non-elite athletes. METHODS Blood samples were drawn 1 week before the race, directly after completion of the race, and 1 week later. RESULTS Serum cortisol and prolactin showed distinct rises 1 h after the race and returned to baseline 1 week later. Androstenedione and dehydroepiandrosterone sulphate did not show any changes. Total testosterone as well as free testosterone dropped significantly 1 h after the race but returned to baseline 1 week later. CONCLUSION In this particular group of non-elite, middle-aged marathon runners, the race resulted in an acute increase in serum cortisol and prolactin levels and in a concomitant decline in testosterone level. The aforementioned changes returned to baseline 1 week later.

Abstract
Tuberculosis (TB) caused by the human pathogen Mycobacterium tuberculosis, is the leading cause of morbidity and mortality caused by infectious agents worldwide. Recently, there has been an ongoing concern about the clarification of the role of specific human genes and their polymorphisms involved in TB infection. In the vast majority of individuals, innate immune pathways and T-helper 1 (Th1) cell mediated immunity are activated resulting in the lysis of the bacterium. Firstly, PTPN22 R620W polymorphism is involved in the response to cases of infection. The Arg753Gln polymorphism in TLR-2 leads to a weaker response against the M. tuberculosis. The gene of the vitamin D receptor (VDR) has a few polymorphisms (BsmI, ApaI, Taq1, FokI) whose mixed genotypes alter the immune response. Solute carrier family 11 member (SLC11A1) is a proton/divalent cation antiporter that is more familiar by its former name NRAMP1 (natural resistance associated macrophage protein 1) and can affect M. tuberculosis growth. Polymorphisms of cytokines such as IL-10, IL-6, IFN-g, TNF-a, TGF-b1 can affect the immune response in various ways. Finally, a major role is played by M. tuberculosis antigens and the Ras-associated small GTP-ase 33A. As far as we know this is the first review that collates all these polymorphisms in order to give a comprehensive image of the field, which is currently evolving.

Abstract
Clear decrements in lung function have been reported in patients with diabetes over the past two decades, and many reports have suggested plausible pathophysiological mechanisms. However, there are no reports of functional limitations of activities of daily living ascribable to pulmonary disease in patients with diabetes. This review attempts to summarize the available information from the present literature, to describe the nature of the lung dysfunction in diabetes and the emerging clinical implications of such dysfunction.

Abstract
Urinothorax is a rather rare cause of pleural effusion and its potential mechanism is urinary tract obstruction or trauma that results in urine leakage and accumulation inside the pleural space. Patients with non-Hodgkin lymphoma could present with pleural effusion due to mediastinal lymphadenopathy or extrathoracic manifestation such as urinary tract obstruction, the latter described in our case report. Physicians must be aware even of the more occult mechanisms of pleural fluid accumulations which could point to extrathoracic manifestations of involvement.

Abstract
OBJECTIVE The aim of the study was to examine the quality of the characteristics of Erectile Dysfunction (ED) in men with Obstructive Sleep Apnea Syndrome (OSAS) and to investigate whether there is an improvement with the use of continuous positive airway pressure (CPAP) therapy. MATERIALS AND METHODS Fifteen men with OSAS and sexual dysfunction have been investigated in this follow-up study. The treatment period was for 12 weeks and the therapeutic CPAP levels were determined during the full night of the therapeutic titration. RESULTS In our 15 treated patients, the International Index Erectile Function (IIEF) total and all domain scores had increased after the CPAP treatment compared to the baseline, except for that of sexual desire domain. CONCLUSIONS CPAP therapy can improve the sexual function in ED patients with OSAS.

Abstract
OBJECTIVE The aim of this work was to study whether social factors are risk factors for obstructive sleep apnea (OSA). A second objective was to investigate gender differences in relation to referral to a sleep laboratory for sleep-related breathing symptoms. STUDY DESIGN A retrospective cross-sectional study was conducted in the referral sleep disorders laboratory in the tertiary University Hospital in Patras in southwest Greece. A sample of 362 subjects originated from this geographic region was screened for social characteristics, i.e., marital status, occupation, and education. RESULTS The apnea hypopnea index (AHI) was approximately three times as high in men as in women (p < 0.05). Snoring was reported to be a symptom by 76.6% of males and 75% of females. Excessive daytime sleepiness (EDS) was reported by 25.5% of males and 15% of females. Arousals during sleep were reported by 5.7% of men and 10% of women. The ratio of subjects with concomitant disorders or symptoms did not differ between sexes (p > 0.05). The influence of age, body mass index (BMI), gender, smoking, and social characteristics on AHI was examined by multinomial logistic regression. The following factors remained independent risk factors for the presence of moderate to severe OSA (i.e., AHI > 15/h compared with AHI < 5): (1) Gender: the odds ratio (OR) of males to females was 6.23 (CI = 1.89-20.5). (2) Obesity: the OR of subjects with BMI >30.5 kg/m(2) in comparison to those with lower BMI was 3.83 (CI = 1.86-7.86). (3) Marital status: The OR of married subjects to singles was 2.30 (CI = 1.01-5.32). (4) Occupational status: The OR of subjects outside the work force was 3.85 (CI = 1.16-12.74) and that of the self-employed was 1.70 (CI = 0.70-4.10) compared to a reference group of clerks/employees. CONCLUSION In our study factors associated with the presence of sleep apnea include gender (men), obesity, marriage, and self-employment or being outside the work force.

Abstract
Skin prick tests (SPTs) play an important role in the diagnosis of bakers asthma and epidemiological field studies on frequencies of sensitization to wheat or rye flour. In many epidemiological studies the investigators have tried to reveal the determinants of specific sensitization, and atopy appears to be a very strong determinant for sensitization to flour allergens. Age and gender have not reported to be determinants of sensitization. Only one study found that sensitization in wheat flour with skin prick test was significantly associated with cigarette smoking. Few data are available on sensitization to wheat flour in populations without occupational exposure to bakery allergens. The aim of this study was to investigate the sensitization of wheat flour and other baking allergens (oat, barley, and rye flour) in traditional bakers and in cleaners in a big hospital in the same area. In addition the correlation of atopy with specific sensitization and the correlation of specific sensitization with age, sex, working hours, working years, smoking status and pack/years with use of skin prick tests.

Abstract
Obstructive sleep apnea syndrome (OSAS) is part of a metabolic syndrome, whose main aspects are obesity, hypertension and diabetes, already incriminated for cardiovascular events. The evaluation of the effect of OSAS on the hormonal profile of patients shows a number of complex interactions that preclude the exact role of this syndrome among the numerous derangements on hormone levels as well as the effect of continuous positive airway pressure treatment, since many of the changes are known to occur with obesity as well. The clarification of the exact role and the mechanisms underlying these changes will help to stratify the cardiovascular and other health risks of this syndrome as well as the better application of CPAP therapy.

Abstract
Obstructive sleep apnoea (OSA) is a complex disease entity strongly influenced by genetic factors, especially those that affect obesity and fat distribution, upper airway muscle tone, craniofacial morphology, ventilatory control and sleep, giving rise to the OSA phenotype. OSA can also be considered a metabolic syndrome which adversely affects multiple organ systems, especially the cardiovascular system and the brain. The most widely used clinical marker for the diagnosis of OSA is the apnoea-hypopnoea index, calculated by polysomnography. A percentage of 35 to 40% of its variance can be attributed to genetic factors. Therefore, the identification and elucidation of the genes implicated in the pathogenesis of OSA becomes a matter of extensive research and could lead to the development of therapeutic agents that can have a beneficial effect on the natural course of OSA.

Abstract
This report describes a female patient with bronchiectasis, presented to our department with recurrent hemoptysis. Bronchoscopy revealed nothing else but blood arising from the upper lobe bronchus. High resolution computing tomography of the lung (HRCT) revealed bronchiectasis of the upper lobe. A right upper lobectomy was performed. Behind bronchiectasis multiple nodular lesions, 5-10 mm were observed. Histological and immunohistochemical examination revealed findings consistent with peripheral typical bronchial carcinoids.

Abstract
The aim of this study was to compare the efficacy of sildenafil and continuous positive airway pressure (CPAP) in men with erectile dysfunction (ED) and obstructive sleep apnea syndrome (OSAS). In all, 30 men were randomly treated for 12 weeks either with sildenafil 100 mg before intercourse (15 men) or CPAP during night time sleep (15 men). Under sildenafil, 97/180 (53.9%) of attempted intercourses were successful compared to 33/138 (23.9%) under CPAP. The mean IIEF (erectile function domain score) was 12.9 and 9.3 after sildenafil and CPAP treatment, respectively (P=0.007), compared to 7.9 and 7 at baseline. In all, 53.3% of patients were satisfied with sildenafil and 20% with CPAP for ED treatment (P=0.058). Although sildenafil was superior to CPAP, comorbidities and OSAS per se possibly resulted in a lower effectiveness of sildenafil compared to that in the general population of ED men. While about half of the patients were not satisfied even with the more effective treatment, we conclude that a combination of the two therapeutic tools or a different therapeutic mode should be studied further.
