A cross-sectional study was conducted in a randomly selected factory producing Portland cement in eastern Saudi Arabia to determine the prevalence of respiratory symptoms and diseases and chest x-ray changes consistent with pneumoconiosis in the employees. A sample of 150 exposed and 355 unexposed employees was selected. A questionnaire about respiratory symptoms was completed during an interview. Chest x-rays were read according to the ILO criteria for pneumoconiosis. Dust level was determined by the gravimetric method. Concentrations of personal respirable dust ranged from 2.13 mg/m3 in the kilns to 59.52 mg/m3 in the quarry area. Cough and phlegm were found to be related to cigarette smoking, while wheezing, shortness of breath, and bronchial asthma were related to dust levels. It is recommended that engineering measures be adopted to reduce the dust level in this company, together with health monitoring of exposed employees.

144 workers of two Ukrainian fodder production plants have been examined. Respiratory troubles such as chest tightness, cough with phlegm, wheezing were revealed not only in the group of workers exposed to high levels of endotoxins but also in the group exposed to low concentrations. The prevalence of ODTS (Organic Dust Toxic Syndrome), mucosal irritation syndrome, bronchial hyperresponsiveness and obstructive changes of lung function were related to levels of endotoxins in the air of work zone. Respiratory challenge test is the principal to reveal the early signs of obstructive changes of lung function. The protective measures for prophylaxy of the development of occupational diseases in workers exposed to organic dust were proposed.

Exposure to methyl methacrylate (MMA), total dust and health symptoms were investigated in 20 dental laboratories located in Tehran, Iran. Time-weighted average (TWA) of MMA and peak concentrations were determined, using XAD-2 tubes followed by GC-FID analysis. Total dusts were evaluated gravimetrically. Health symptoms were asked using a questionnaire. TWA for technicians with direct and indirect exposure to MMA were 327.28 +/- 79.42 and 282.9 +/- 41.84 mg/m3, respectively. Peak concentration of MMA for those technicians were 337.0 +/- 36.81 and 328.88 +/- 45.40 mg/m3, respectively. There were no significant differences between TWA of MMA and peak concentration in different weekly workdays; however, within-day variations were observed (P < .05). TWA of MMA and peak concentration correlation with the laboratory volume were 0.61-0.65. Dust exposure of technicians was 2.35 +/- 2.70 mg/m3. Cough and skin dryness were the common health symptoms. Smoking and asbestos exposure history were factors influencing cough prevalence (p < .05). It is concluded that the current Short-Term Exposure Limit (STEL) is not low enough to protect technicians against the adverse effects caused by MMA.

Clinically significant pulmonary disease caused by non-tuberculous mycobacteria such as Mycobacterium avium Complex (MAC) usually occurs upon pre-existing lung diseases or immune-deficiency. In 1992, a particular presentation of pulmonary MAC, occuring in otherwise healthy middle-aged women, was described with pulmonary consolidations localized in lingula and middle lobe. For this specific, rare condition, the term Lady Windermere syndrome was introduced. We report a particular case of this syndrome, in which an otherwise healthy individual developed clinically significant disease upon MAC (subtype: Mycobacterium avium) infection of the right middle lobe and lingula of the lung. The patient did not have the classical risk factors for developing this syndrome (e.g. habitual cough suppression, long and narrow bronchi) indicating their modest contribution in the pathogenesis. In our case, guideline based therapy was found to be inadequate because of multi-drug resistance, so an alternative treatment regime was given with good clinical result.

The aim of this study was to evaluate the lung disorders of the workers exposed to rush smear dust. A cross sectional study was carried out on 1,709 current workers (788 male, 921 female) in 80 factories. All subjects were asked by questionnaire, and health examination including chest X-ray was conducted for 661 workers in 35 factories. Lung function test was also examined for 119 non-smoking males among 661 subjects. Dust samplings were collected and total and respirable dust concentrations at 127 spots in 35 factories were measured. The geometric mean dust concentration in the workshops was up to 20.00 mg/m(3), and the geometric mean respirable dust concentration reached 8.22 mg/m(3). The mean quartz concentration of accumulated dust was 29.2%. The prevalence of radiographic small opacities profusion category > or = 1/0, according to the ILO 1980 Classification System, was 2.6% among 661 employees. One worker was found to have pneumoconiotic findings of 2/2 profusion accompanied with large opacity. The prevalence of pneumoconiosis (1/0 or more) correlated with cumulative dust exposure (r=0.192, p<0.0001). The similar relationship was found between the prevalence rate of cough or sputa and worksite dust concentration. In non-smokers, a positive association was found between the prevalence of cough and occupational exposure duration (r=0.080, p=0.004). Approximately 19.3% and 34.5% of employees suffered from respiratory impairment for FVC and FEV1.0, respectively. This is the first report of "rush" pneumoconiosis in China. Rush mat workers were found to be at high risk for pneumoconiosis, a preventable disease. Our results showed a dose-response relationship between rush-mat dust level and the prevalence of pneumoconiosis. Similar relationship between the prevalence of cough and sputum and the work duration was found for non-smoking workers but not for smoking workers.

We present a patient with Lady Windermere syndrome after coronary bypass operation. To avoid the sternal pain that occurred after every cough episode, this patient used to receive large doses of antitussive drugs. In a poorly drained lung, this usage leads to the development of regions of colonization with Mycobacterium avium complex. It is concerning that the lack of diagnosis for 18 months in this patient occurred because of the insidious symptoms that mimic bronchitis. This case emphasizes how important it is for patients after a median sternotomy to receive adequate analgesic and physiotherapeutic support in order to avoid chronic inflammation and infection of the lungs.

Carpet weaving among children is common in rural Pakistan, but little information is available on the health effects of this work. A total of 628 carpet-weaving children and 292 non-working children from 10 rural villages were evaluated with questionnaires and physical exams. Fifty-five home-based and 30 shed-based worksites in these villages were assessed. Girls comprised the majority of working (73%) and non-working (69%) children; the mean age for both boys and girls was 10 years. The mean number of hours worked daily was 7.2 for males and 6.8 for females. Dust exposure in homes was generally higher than in sheds. Working children had significantly greater odds of joint pain (OR = 2.8), dry cough (OR = 2.5), cuts/bruises (OR = 22.1), Phalen's sign (OR = 17.2), and neck/shoulder abnormalities (OR = 14.2). Symptoms and signs of acute and repetitive injury and respiratory symptoms were more common among carpet-weaving children than their non-working peers.

A 59-year-old woman with a body mass index of 30 and an edematous, tender goiter was scheduled for subtotal thyroidectomy. She had a history of dyspnea, cough, hoarseness, sleep disturbance in the supine position, difficulty in expelling sputum, and inability to rotate her neck to the left. Chest CT showed an adenomatous goiter, measuring 42 x 57 x 105 mm, with invasion into the mediastinal space, 17 mm right glottic shift, and 21 mm right tracheal shift. Because of her goiter and laryngo-tracheal shift, we anticipated a difficult intubation and ventilation. Awake fiberoptic intubation was selected for anesthesia induction, and was easily performed using a Parker Flex-Tip tracheal tube (Parker Medical, Highland Ranch, Colorado, USA), after intravenous injection of 200 microg of fentanyl, 8% lidocaine pump spray on the larynx with a direct laryngoscope, and 5 ml of 4% lidocaine spray on the vocal cords and trachea through a bronchoscope. The operation was completed successfully without any adverse events. Awake fiberoptic intubation with a Parker Flex-Tip tracheal tube is easily performed in a patient with a difficult airway due to obesity, goiter, and laryngo-tracheal shift.
