This study explored health and education professionals' perceptions of the health benefits and barriers of different ear health programs used in lower primary school classes in two district education areas in the Goldfields South East Health Region, Western Australia. Health and education staff providing services to children in kindergarten to year three primary school classes were sent a questionnaire about ear health programs provided in their school. Sixty-one questionnaires were returned from 43 teachers, 14 community health nurses, three Aboriginal health workers and one teacher's assistant. Some schools implemented all the ear health programs examined at all year levels while others implemented only one of the programs. Teachers, community health nurses and Aboriginal health workers identified that all ear health programs were beneficial to students. Reported physical health benefits included reduced ear infections, early detection of ear infections and improved hearing. Behavioural benefits included improved concentration, alertness and attention in the classroom. Barriers to implementing the programs were obtaining consent from parents/carers, student transience and attendance, time to implement and conduct the programs and human and physical resources. Evaluation methods used varied from no evaluation for the Breathe Blow Cough and tissue spearing programs to limited data collection for audiometry, otoscopy and ear toilet programs. Respondents perceived that ear health programs were effective in improving health and behavioural outcomes for children. A formal pre-post evaluation to provide objective data to confirm this is needed to inform policy around this important health issue.

There is currently no national data on the effects of polyvinyl chloride (PVC) exposure on pulmonary function. In this study we recruited workers and administrative staff from two PVC plants between July 2008 and July 2009. A questionnaire, pulmonary function tests, carbon monoxide diffusion capacity, and peak flows were recorded. Particulate matter analyses were performed by the Adana Central Laboratory of the Directorate of Occupational Health and Safety. Data were analyzed with SPSS 13.0 software. Nine of the 147 subjects were female. The incidence of a cough was more common in the administrative group. Of the study population, 59.1% were smokers. Tobacco addiction significantly increased cough and dyspnea [OR= 1.10 (1.00-1.20, 95% CI) p= 0.007 and OR= 1.08 (1.02-1.14, 95% CI), p= 0.008, respectively]. Dust exposure was correlated with the incidence of a cough [OR= 0.20 (0.04-0.80, 95% CI) p= 0.008]. The period of work correlated with sputum production [OR= 1.00 (1.00-1.02, 95% CI) p= 0.044]. The FVC% was significantly higher in the administrative group, and FEV1/FVC and DLCO were higher in the exposed group. Tobacco addiction increased the risk of airflow limitation, as evaluated by FEV1/FVC < 70% and FEF25-75 < 50% [OR= 1.15 (1.06-1.25, 95% CI) p= 0.001 and OR= 1.09 (1.02-1.17, 95% CI) p= 0.010, respectively]. Tobacco addiction and increasing duration of work had a negative influence on DLCO in the exposed group (r= -0.270, p= 0.025 and r= -0.210, p= 0.037). In the exposed group PEF variability was significantly greater on workdays, compared with rest days. This study shows that tobacco consumption has a greater affect on the airways than PVC dust exposure. A median of 36 months exposure to PVC dust had no significant impact on pulmonary function parameters, except for DLCO and PEF variability.

Nontuberculous mycobacterial lung disease (NTMLD) in immunocompetent patients is an increasingly important epidemiologic concern. However, risk factors associated with susceptibility to NTMLD are not completely known. A prevalence of NTMLD appears to be rising, mainly in some populations such as middle-aged or elderly thin women, (a group including those with Lady Windermere syndrome) with neither remarkable history of respiratory disease nor smoking habit. Right middle lobe (RML) and lingula are often involved. Various predisposing factors and genetic defects have been described as possible causes of development of NTMLD, namely: voluntary suppression of cough, RML anatomical factors, menopause and mutations in cystic fibrosis transmembrane conductance regulator (CFTR). Malnutrition is also an important and common risk factor associated with other mycobacterial disease like tuberculosis (TB) and its probable association with NTMLD as have been pointed out for some authors. However, a real description of all nutritional aspects and eating habits of patients prior to NTMLD diagnosis is lacking. We hypothesized that malnutrition and eating disorders like anorexia nervosa could be risk factors that may promoting NTMLD. From a clinical viewpoint, if this hypothesis proves to be correct, eating habits and nutritional aspects should be taken into account in the diagnosis process of suspected NTMLD, since they are easily identifiable and treatable conditions.

Dust can be produced by almost all production processes in Portland cement factory. Dust exposure potentially can affect respiratory function. But evidence for respiratory effect of cement dust exposure has not been conclusive. In this study we assessed effect of cement dust exposure on respiratory function in a cement production factory. A respiratory symptoms questionnaire was completed and pulmonary function tests were carried out on 94 exposed and 54 non exposed workers at a cement factory in the east of Iran. Additionally, respirable dust level was determined by the gravimetric method. X-ray fluorescence (XRF) technique was performed to determine the silica phases and the SiO(2) contents of the bulk samples. The arithmetic means (AM) of personal respirable dust were 30.18 mg/m(3) in the crushing, 27 mg/m(3) in the packing, 5.4 mg/m(3) in the cement mill, 5.9 mg/m(3) in the kiln and 5.48 mg/m(3) in the maintenance that were higher than threshold limit value (TLV) of the American Conference of Governmental Industrial Hygienists (ACGIH) which is 5 mg/m(3). This value in the unexposed group was 0.93 mg/m(3). In this study cough, sputum, wheezing and dyspnea were more prevalent among exposed subjects. Exposed workers compared to the unexposed group showed significant reduction in Forced Expiratory Volume in one second (FEV(1)), Forced Vital Capacity (FVC), and Forced Expiratory Flow between 25% and 75% of the FVC (FEF(25-75%)) (P<0.05). It can be concluded that in our study there was close and direct association between cement dust exposure and functional impairment among the cement factory workers.

Described by Reich and Johnson in 1992 [2], the Lady Windermere syndrome occurs exclusively in non-smoking women over the age of 60 years, without significant pre-existing pulmonary disease. It comprises bronchial dilatation, typically in the middle lobe and lingula, together with secondary infection by atypical mycobacteria (Mycobacterium avium in the first cases). Among the 17 cases of atypical mycobacterial infection that we have seen in the past 14 years, there were seven cases of this syndrome. It was associated with cough, sputum, sometimes haemoptysis, febrile episodes and deterioration of general health. The diagnostic criteria and treatment were defined by the American Thoracic Society. The pathophysiological hypothesis proposed by Reich and Johnson was that voluntary suppression of the cough led to congestion of the bronchi and secondary infection with atypical mycobacteria. Currently it is thought more likely that the following factors are involved: progressive increase in dilatation of small bronchi, delayed diagnosis, morphological abnormalities of the thorax, hormonal factors, immune deficiency, genetic neutrophil dysfunction, and even heterozygous forms of cystic fibrosis.

We report three children with an unusual radiological sign: "trachea with an air fluid level." We suggest this is related to paucity of cough leading to recurrent chest infections. Voluntary cough suppression as a cause of chronic lower respiratory tract infection is recorded in adults (The Lady Windermere Syndrome) but has not previously been reported in children. We propose that in these children impaired airway mucus clearance may be also be caused by voluntary cough suppression. However, the complex physiology of coughing means it is difficult to distinguish between true voluntary cough suppression and paucity of cough due to a subtle neurological deficit. In two patients, the cycle has led to permanent lung damage with bronchiectasis and reduced lung function. In the third, early diagnosis and multidisciplinary intervention has so far delayed progression to bronchiectasis. With greater awareness of this phenomenon in children, there is potential for effective early intervention with medical, physical, and psychological therapies.

Myeloid sarcoma is a rare extramedullary solid tumor consisting of immature myeloid cells and most commonly involving the bone, skin, lymph nodes, soft tissue, gastrointestinal tract and testis. Mediastinal myeloid sarcoma is very rare. There are two major types of myeloid sarcoma: granulocytic sarcoma and monoblastic sarcoma, according to immature cell type. Myeloid sarcoma is found in 2%-8% of patients with acute myeloid leukemia (AML). Myeloid sarcoma may develop before or concurrently with AML, or may be the initial manifestation of AML relapse in previously treated patients. Blast transformation of some form of myeloproliferative neoplasm or myelodysplastic syndrome may also manifest as myeloid sarcoma. A major differential diagnostic problem is isolated primary myeloid sarcoma without bone marrow and peripheral blood involvement, which may precede leukemic stage for months or years, and which is frequently misdiagnosed, mostly as malignant lymphoma. A case is presented of a 56-year-old female patient complaining of weakness, vertigo, dry cough and breathing difficulties. Clinical examination revealed enhanced vascular pattern on the right chest and right arm edema. Computed tomography (CT) of the thorax showed an expansive growth measuring 11 cm craniocaudally in the anterior mediastinum. Fine needle aspiration cytology of tumor mass yielded a scarcely cellular sample with individual atypical immature cells, fine chromatin structure and scarce cytoplasm with occasional granules and Auer rods. Considering the morphological, cytochemical and immunocytochemical characteristics of immature cells, the diagnosis of myeloid sarcoma was made and verified by histopathology of tumor biopsy sample. Immature cells were not found by analysis of bone marrow puncture sample, immunophenotyping of bone marrow cells and bone biopsy analysis. As immature cell proliferation was not detected in bone marrow and peripheral blood, while spread of the disease beyond the mediastinum was ruled out by imaging methods (CT, ultrasonography), it was decided to be a primary non-leukemic form of mediastinal myeloid sarcoma. Myeloid sarcoma should be taken in consideration on differential diagnosis of solid tumors because making an accurate diagnosis is necessary for timely initiation of appropriate therapy. Weakly expressed or lacking clear signs of myeloid differentiation may hamper morphological diagnosis. As isolated myeloid sarcoma is a very rare entity frequently resembling lymphoma in clinical presentation, it poses a major diagnostic challenge for both morphologists and clinicians.

Dust generated during the handling and processing of cotton causes ill health of ginning workers. The purpose of this study was to determine the prevalence of respiratory symptoms among cotton-ginning workers. This study involved 188 workers of 10 cotton-ginning factories. Forced vital capacity (FVC), peak expiratory flow rate (PEFR), and forced expiratory volume in 1 s (FEV1) declined significantly with increasing duration of exposure (p < .001) of the cotton-ginning workers. Results of a standard respirator medical evaluation questionnaire indicated that, depending on duration of exposure, 51%-71% of cotton-ginning workers suffered from chest tightness, 55%-62% experienced chest pain, while 33%-42% of the workers reported frequent cough. Blood tests of the workers showed higher values of erythrocyte sedimentation rate, eosinophils, and white blood cells when exposure was longer. Byssinosis symptoms were observed among the workers. We recommend regular periodical medical check-ups, compulsory use of personal protective equipment, and proper ventilation at the workplace.

Multiple pulmonary hamartomas (PH) occur rarely, are mostly seen in females, and are usually leiomyomatous hamartomas. Here, we report an extremely rare case of a 30 years old male patient diagnosed as multiple pulmonary chondromatous hamartomas. He was admitted on May 2015 to our hospital for a 3 months history of cough. Multiple nodules in the right lung were detected on chest X-rays during a routine checkup 9 months ago and in a subsequent chest computed tomography (CT). However, he abandoned medical follow-up because he was asymptomatic. Nine months later, rare and atypical CT findings with progression were observed during this visit so that pulmonary metastases from an unknown primary tumor was suspected. Positron emission tomography/computed tomography (PET/CT) scan showed mild fluorine-18 fluorodeoxyglucose ((18)F-FDG) uptake in the lesions and no abnormal foci in any other part of his body. A posterolateral thoracotomy was performed. Pathologic features were consistent with those of pulmonary chondromatous hamartomas.
