Eleven hundred and nine iron mine workers aged 35 to 55 with normal chest radiographs were submitted to a pulmonary examination consisting of a questionnaire, a clinical examination, and pulmonary function testing including an acetylcholine challenge test. A positive response (decrease of FEV1 of more than 10%) was observed in 210 subjects (Ace+). The remaining 899 had a negative response (Ace-). Bronchitis, asthma, dyspnoea, and obstructive syndrome were more frequent in the Ace+ group. Five years later, 820 subjects were reexamined: occasional cough and sputum and chronic bronchitis appeared more frequently among subjects without symptoms at the first examination but with a positive acetylcholine challenge test. The obstructive syndrome was more often observed and regressed more rarely in the Ace+ group. The results confirm the use of a test of bronchial hyperreactivity as a means of identifying subjects at risk from chronic obstructive lung disease.

The patient had been employed in an asbestos factory for four years from the age of 16. Five years ago, she complained of sputum and cough, and she was treated for chronic bronchitis. From March, 1977, when she was 53 years old, hydrothorax and ascites increased, her weight decreased and she was hospitalized for cachexia. The clinical diagnosis of malignant diffuse mesothelioma was made on the presence of atypical cells in the effusions. Atypical cells showed a positive colloidal iron staining test and positive hyaluronidase digestion test. Asbestos bodies were found in the sputum. The patient died on February 1978. Postmortem confirmed asbestosia and mesothelioma which was scattered over the pleura, pericardial sac, diaphragma, peritoneum and pancreas. In addition, bronchiolo-alveolar cell type lung cancer was found localized in the lower lobe of the left lung. The electron beam diffraction disclosed the asbestos as amosite (brown asbestos).

Zygomycosis is an uncommon, but frequently fatal, fungal infection caused by members of the class Zygomycetes. The risk factors include diabetes mellitus, uremia, leukemia and use of deferoxamine as an iron-chelating agent; healthy persons also are occasionally infected. Those fungi, spread by their ubiquitous spores, most frequently involve the respiratory system. Rhinocerebral zygomycosis occurs predominantly in patients with uncontrolled diabetic ketoacidosis. Pulmonary zygomycosis most frequently is observed in granulocytopenic and corticosteroid-treated patients. Other clinical manifestations are gastrointestinal, cutaneous, disseminated and miscellaneous. This report concerns a previously robust farmer who suffered from left upper lung abscess caused by Rhizopus spp.-one member of the order Mucorales. Initially, it was intended to administer amphotericin B to a total dose of 2,000 mg; however, the patient could not tolerate such side effects as nausea, vomiting and refused further management when the cumulative dose was 948 mg. However, he did recover without further fever and cough. Chest X-ray, followed every three months, disclosed satisfactory improvement.

Efficiency of cough for clearing mucus from the lungs is believed to be a function of peak airflow velocities in the airways. Initial transient supramaximal flows are characteristic of cough, and these peak flow rates can be enhanced by placing a triggered shutter at the mouth, serving the role of the epiglottis. Using radiolabeled monodispersed aerosols (99mTc-iron oxide) and gamma camera analysis, we measured over a 2-h period the efficacy of 60 voluntary vs. shutter coughs for clearing mucus from the airways of patients (n = 15) with chronic airway obstruction (mean ratio of forced expired volume in 1 s to forced vital capacity = 0.55). In a subset of patients (n = 9), we also measured the efficacy of forced expirations, or huffs, without glottis closure. Peak flow rate was greater for shutter than voluntary coughs [9.4 +/- 2.0 (SD) vs. 4.1 +/- 1.9 l/s; P < 0.001]. Retention at 60 min (as a fraction of initial deposition) was significantly different for the 3 study days (control, 0.83 +/- 0.17; voluntary cough, 0.69 +/- 0.18; shutter cough, 0.75 +/- 0.19; P = 0.01), but only control vs. voluntary cough values were significantly different from each other (P = 0.01). In contrast, retention at 120 min was significantly different for the 3 days, but both voluntary and shutter coughs were significantly different from control (P = 0.01 and P = 0.02, respectively) (control, 0.73 +/- 0.16; voluntary cough, 0.61 +/- 0.20; shutter cough, 0.65 +/- 0.20). Patients studied with buffs showed a clearance rate faster than control and similar to that associated with voluntary cough.(ABSTRACT TRUNCATED AT 250 WORDS)

The dilemma of private practitioners is whether to prescribe or not to prescribe iron supplements on suspicion of anaemia. This cross sectional study was done in an urban squatter settlement with a primary health care centre to assess the significance of symptoms and a history of associated diseases in the diagnosis of anaemia. A total of 321 children were sampled from 1800 children < 5 years of age in a population of 11,000, by systematic random sampling. Mothers were asked about the presence of assumed associated symptoms and diseases which were listlessness, irritability, anaemia, pica, poor weight gain, diarrhoea, acute respiratory infection and malaria in last 3 months. There was significant association between anaemia (Hb < 11 gms%) and irriability (P < .02), anorexia for solid foods (P < .04), pica (P < .001), episode of diarrhoea (P < .001) and poor weight gain (P < .006). There was no significant association between malaria, cold, cough and anaemia. Children with these symptoms complex should receive iron supplements.

Dosing of pediatric medications must be accurate. Combining constants in the usual calculation for amoxicillin dosing derives the Rule of Six (6 mg/lb per dose) for dosing. This rule generalizes to most pediatric antibiotics. The Decimal Move Rule (0.1 mL/lb per dose) can be used to dose many over-the-counter cough and cold remedies, bronchodilators, and iron preparations. A number of helpful hints to improve compliance and three comprehensive dosing tables are presented.

Pregnancy is associated with special problems with respect in selection of medication and dosage, primarily due to potential teratogenic or toxic effects on the fetus by the drug itself, and secondly due to the physiologic adjustments in the mother in response to pregnancy. This prospective survey was designed to record the use of medications and the policy of prescribing during the course of pregnancy. In total, 5851 pregnant women residing in a county in southwestern Finland during the period June 15, 1987 and June 14, 1988 were studied, which is 69% of the total amount of births in the same area. Iron and vitamin supplementation was used by all the pregnant women during the third trimester, and by 35% and 88% during the first and second trimesters, respectively. Analgetics were used on an irregular basis by 12% of the pregnant women, and no correlation to the length of pregnancy could be observed. 9% of the women used medication on a regular basis for reasons such as bronchial asthma, arterial hypertension and hyperthyreosis. Some kind of a symptomatic medication was taken by 43% of the women with no correlation of the length of pregnancy, the most common symptoms needing medication being candidiasis, cough, reflux esophagitis and pregnancy-associated hyperemesis. Tocolytic agents had been given to 8% of the pregnant women. Most tocolytics were used during the end of the second trimester and beginning of the third one. It is concluded that the general use of medicines is quite reasonable in the normal pregnant population in Finland. Iron supplementation should probably be more individualized instead of regular use.

The amount of water supply in Japan was 16 billion ton as of 1989. Water from rivers and other sources is purified, sterilized and then supplied to the residents through conduits. When conduits are accidentally damaged, they must be repaired by the workers of the Waterworks Bureau of the local government. In this task, the workers are exposed to airborne dust which develops while digging and filling the ground and cutting the conduit and the concrete covering the road. The purpose of the present study was to estimate the airborne dust exposure level among the workers and to investigate its effect on their respiratory organs. First, we measured the total dust exposure concentration of 20 conduit repair workers and the total dust concentration in 10 office rooms. Second, we conducted a self-administered questionnaire survey to estimate the prevalence of respiratory symptoms among the employees of 119 Waterworks Bureaus. The subjects of the analysis were 322 conduit repair workers and as their controls 345 clerical/engineering workers. The results can be summarized as follows: 1) The average daily total dust exposure while repairing conduits ranged from 0.27 to 5.05 mg/m3 (mean = 0.91 mg/m3), while that while exchanging water meters from 0.23 to 0.52 mg/m3 (mean 0.41 mg/m3). These values were 4.6 and 2.1 fold higher than the total dust concentration in office rooms (mean = 0.20 mg/m3). 2) With the use of fluorescent X-ray method, iron and aluminum were detected in all samples collected while repairing conduits and the intensity of X-ray increased with increase in weight of collected dust. Iron exposure concentration ranged from 0.006 to 0.095 mg/m3, which is much higher than the levels in the air in urban areas. Iron and aluminum could not be detected by fluorescent X-ray method in most of the samples collected in office rooms. These findings indicate that the main element in the dust collected while repairing conduits is soil, while that in office rooms is tobacco smoke. 3) Among the smokers, the prevalence of cough and phlegm was significantly higher in conduit repair workers than in clerical/engineering workers. A similar tendency was observed among ex-smokers and non-smokers, but the difference was not significant.

Using radiolabeled, monodispersed aerosols (99mTc-iron oxide) and gamma camera analysis, we measured the efficacy of cough for clearing mucus from the airways of the lung following inhalation of the bronchodilator ipratropium bromide (IB) (Atrovent, Boehringer Ingelheim, Inc), a drug that has been shown to have no effect on mucociliary clearance in COPD. Clearance of radiolabeled aerosol was studied over a 2.5-h period on three separate days, a control day with no coughing, and two study days during which the patient performed controlled cough maneuvers over the course of clearance measurements following IB or placebo therapy (double blind, crossover). Fifteen patients, age > 45 years, with stable moderate-to-severe airway obstruction (mean FEV1/FVC = 0.45) were studied. IB diminished the effectiveness of cough for clearing the radiolabeled particles from the airways. This effect of IB on cough clearance may be due to (1) changes in the airflow dynamics induced by bronchodilation or (2) altered rheology or depth of airway secretions.

Idiopathic pulmonary haemosiderosis (IPH) is a disorder characterised by the triad of haemoptysis, diffuse parenchymal infiltrates on chest roentgenogram and iron-deficiency anaemia. It is a diagnosis of exclusion and the prognosis is bleak despite the varied management options. We report a case of IPH occurring in a child who presented at four months of age with cough, wheeze, haemoptysis and pallor and whose symptoms are currently controlled with high-dose inhaled budesonide and low-dose oral prednisolone.
