After receiving reports of lead poisoning in two workers at a secondary lead smelter, we evaluated the health status of 38 current smelter workers and 87 of their household contacts by questionnaires, physical examinations, and laboratory tests. Fatigue, cough, and diarrhea were the most frequent symptoms in plant employees; each occurred in at least a third. The most frequent physical finding, hand tremor, occurred in 10 of 33 plant employees. Twelve employees had blood lead concentrations at or above 80 microgram/100 ml, and 17 others had blood lead concentrations at or above 60 microgram/100 ml. All physical signs possibly due to excess lead absorption were manifested by employees with blood lead levels of 60 microgram/100 ml or greater, with one exception. Household contacts of employees had few symptoms suggestive of excess lead absorption.

Twenty-four 4-week-old poults, free from Mycoplasma meleagridis and M. gallisepticum, were inoculated with a velogenic viscerotropic strain of Newcastle disease virus. Clinical signs (gasping, coughing, and dyspnea) developed 4-5 days postinoculation, continued until nervous derangement appeared, and then (usually 3 days after initial clinical signs appeared) declined in severity. Prominent nervous signs were paresis and paralysis of the extremities, with pronounced head-shaking. The most constant gross lesions detected involved the airsacs. The abdominal sacs of a few poults contained a large accumulation of yellowish, cheesy exudate and there was cloudiness of the thoracic airsacs of all inoculated poults. A few turkeys had tracheitis with some catarrhal exudates and casts in the lower part of the tracheal lumen. Congestion of lepto-meningeal vessels usually correlated with the severity of the nervous signs. The histologic lesions were characterized by both degenerative and proliferative changes with predominantly mononuclear cell and heterophil infiltrations throughout the body. The obvious lesion seen in the recovery stage of the disease was proliferation of lymphofollicular nodules in the parenchymatous organs.

An open multicenter trial was performed in 242 subjects with chronic obstructive airways disease between August 1987 and April 1989. Two hundred thirty-six subjects were evaluated with regard to safety (m 137, f 99, mean age 49.4 (18-77) years) and 204 subjects with regard to therapeutic efficacy (m 120, f 84, mean age 49.2 (18-77) years). Twelve micrograms (one puff) formoterol was given by metered-dose inhaler twice daily. Investigations were performed at days 0, 14, and subsequently in monthly intervals. Twenty-one patients (10.3%) were sufficiently treated by formoterol alone. One hundred and eighty-three (89.7%) required additional medication, which could be reduced in 90 cases (45.6%). Initially symptoms were present in 201 of 204 patients. At 1 year, 43 patients (21.1%) were symptom-free. At day 0 32.4% of the patients felt "very good" or "good." At 1 year the rate increased to 68.1%. Raw decreased from 0.52 +/- 0.26 (0.06-2.11) kPa.L-1.S at day 0 to 0.33 +/- 0.14 (0.06-0.88) kPa.L-1.S (= -43.5%) at 1 year. FEV1 increased from 1.90 +/- 0.80 to 2.54 +/- 0.97 L (33.7%). The global assessment of therapeutic efficacy was classified as "very good" in 51% (patients) and 47% (doctors), respectively, and as "good" in 38.7% and 42.0%, respectively. Tolerability was "very good" in 82.3% (patients, doctors), and "good" in 12.7% (patients) or 13.7% (doctors). The treatment did not influence blood pressure or heart rate. Twenty-nine patients (12.3% of 236) reported unwanted 39 side effects, such as tremor (6.36%), headache (2.54%), dryness of the mouth (1.27%), cough (0.85%), and dizziness (0.85%).(ABSTRACT TRUNCATED AT 250 WORDS)

Review of the data shows that chest physiotherapy (CP) is effective in clearing secretions from the lungs of patients with copious secretions (i.e., daily sputum production in excess of 30 ml). Assessment of the various components of CP shows that percussion, vibratory shaking, and breathing exercises have little to offer. Although instructed cough, the back up mucus clearance mechanism, is effective in clearing secretions its effect is less than that achieved with the forced expiration technique (FET). Postural drainage (PD) is on the whole successful in helping to drain secretions in the lungs. The administration of a beta 2-agonist via a nebulizer prior to CP in addition to promoting bronchodilation may also help to alter the physical properties of secretions, rendering them more amenable for clearance by FET/cough. Technology regarding high-frequency oscillations (HFO) has yet to be improved and its efficacy in clearing excess secretions proven prior to its inclusion in a CP treatment regimen. Intermittent positive pressure breathing (IPPB) may have a role to play in those patients where conventional CP is not possible. Data with positive expiratory pressure (PEP) are encouraging and direct evaluation is awaited regarding its effect on mucus clearance. With our present knowledge it seems reasonable to recommend that physiotherapists concentrate their CP treatment on the following: administration of a nebulized beta 2-agonist followed by PD and FET.

A mixture containing 3 g of boric acid and 300 mg of cinchocaine chloride prescribed due to painful dental protrusion was accidentally ingested by a 12-month-old girl. She developed violent vomiting and coughing. Irritability, tremor, seizures and a delirious reaction. She was treated with diazepam, intubated, sedated and ventilated. Her diuresis was stimulated with furosemide and fluid. Within the first 24 h she was treated with haemodialysis twice on femoral catheters. Her renal function was unaffected. In two days she fully recovered. The maximum measured levels of boric acid and cinchocaine chloride approximately 6 h after ingestion were 26 micrograms/ml and 71 ng/ml respectively. The plasma half-life of boric acid was 7.0 h and decreased to 3.6 and 4.4 h during the two haemodialyses. The total body clearance of boric acid increased correspondingly from 21 ml/min to 41 and 34 ml/min. The in vitro clearance of boric acid of the dialyser was later determined to be 18 ml/min. It is concluded that haemodialysis is valuable in the treatment of boric acid intoxication because it increases the elimination of the drug even in patients without any sign of renal toxicity.

A cross-sectional epidemiological study was carried out among 141 male subjects exposed to inorganic manganese (Mn) in a Mn oxide and salt producing plant (mean age 34.3 years; duration of exposure, mean 7.1 years, range 1-19 years). The results were compared with those of a matched control group of 104 subjects. The intensity of Mn exposure was moderate as reflected by the airborne Mn levels and the concentrations of Mn in blood (Mn-B) and in urine (Mn-U). A significantly higher prevalence of cough in cold season, dyspnea during exercise, and recent episodes of acute bronchitis was found in the Mn group. Lung ventilatory parameters (forced vital capacity, FVC; forced expiratory volume in one second, FEV1; peak expiratory flow rate, PEFR) were only mildly altered in the Mn group (smokers) and the intensity and the prevalence of these changes were not related to Mn-B, Mn-U, or duration of exposure. There was no synergistic effect between Mn exposure and smoking on the spirometric parameters. Except for a few nonspecific symptoms (fatigue, tinnitus, trembling of fingers, increased irritability), the prevalence of the other subjective complaints did not differ significantly between the control and Mn groups. Psychomotor tests were more sensitive than the standardized neurological examination for the early detection of adverse effects of Mn on the central nervous system (CNS). Significant alterations were found in simple reaction time (visual), audioverbal short-term memory capacity, and hand tremor (eye-hand coordination, hand steadiness). A slight increase in the number of circulating neutrophils and in the values of several serum parameters (ie, calcium, ceruloplasmin, copper, and ferritin) was also found in the Mn group. There were no clear-cut dose-response relationships between Mn-U or duration of Mn exposure and the prevalence of abnormal CNS or biological findings. The prevalences of disturbances in hand tremor and that of increased levels of serum calcium were related to Mn-B. The response to the eye-hand coordination test suggests the existence of a Mn-B threshold at about 1 microgram Mn/100 ml of whole blood. This study demonstrates that a time-weighted average exposure to airborne Mn dust (total dust) of about 1 mg/m3 for less than 20 years may present preclinical signs of intoxication.

A 33-year-old woman farmer developed an acute episode of fever, cough, and shaking chills with persistent shortness of breath. Her PaO2 was 51 with a restrictive pattern on pulmonary function. Her diffusion capacity was 36 percent of predicted. In spite of these abnormalities, she always had normal chest roentgenographic findings. Further studies, including a lung biopsy, led to the diagnosis of farmer's lung disease.

Results of clinical and laboratory examination of animals experimentally infected with Taenia saginata eggs are described. At the early stage of infection, increased temperature, cough, muscle shaking and unstable pace were observed. The locomotive disorders disappeared only on day 50 p.i. Leukocytosis and peripheric eosinophilia were found at the early stage of infection. On days 14-28 p.i. the activity of serum creatine-kinase (CK) significantly increased. The activity of other enzymes (AST, ALT, LD, ALP and ALD) examined was increased only slightly and irregularly. The lipid content in blood serum markedly increased on days 9-16 p.i.

A new oral bronchodilator, clenbuterol, was compared with terbutaline during a 5-week single-blind crossover study in 16 patients with chronic airways obstruction and with cough and sputum production. After a run-in period (1 week), the study was performed in two separated 2-week periods (Phase II and Phase IV), separated by a 1-week drug-free period. Oral clenbuterol was administered at 20 to 30 micrograms 3-times daily, oral terbutaline at 2.5 to 5 mg 3-times daily. The forced expiratory volume in 1 second (FEV1) was measured at the beginning and end of Phase II and Phase IV under baseline conditions, and 1 hour after an oral dose of clenbuterol or terbutaline. Parents recorded subjective and objective information in a daily diary and used no bronchidilator therapy for 12 hours before each visit. Clenbuterol and terbutaline significantly improved baseline FEV1 and the bronchodilator effects of single oral doses were similar. The mean dyspnoea, cough and sputum score values after treatments were lower than during the wash-out period (p less than 0.05). Tremors were noted in 6 patients on clenbuterol and 5 on terbutaline. It is suggested that clenbuterol is a good alternative oral drug for treatment of chronic airways obstruction.

The efficacy of metaproterenol (orciprenaline) and theophylline given orally at currently recommended doses was examined in 34 children with chronic asthma using a randomized double-blind cross-over evaluation of four weeks' duration for each active regimen. No serious adverse effects were seen with either medication, but tremor occurred more frequently with metaproterenol (P less than 0.01). No significant differences were observed in the frequency of nausea, vomiting, headache, or insomnia (P greater than 0.05). Symptoms of wheezing, coughing, exercise intolerance, and interference with sleep were more frequently associated with the oral metaproterenol regimen; completely asymptomatic days occurred 50% more frequently in association with theophylline therapy (P less than 0.01). Mean peak flows, performed twice daily during each of the four-week study periods, were 86 and 92% of predicted for metaproterenol and theophylline, respectively (P less than 0.05). Pulmonary function decreased significantly less with theophylline than with metaproterenol among those who completed six minutes of treadmill exercise during both regimens (P less than 0.05). Corticosteroids, used for acute symptoms that failed to respond to the addition of inhaled metaproterenol, were required in four patients during both regimens, in ten patients only during the metaproterenol regimen, and in one patient only during the theophylline regimen (P less than 0.02). Thus, theophylline therapy was associated with fewer adverse effects, fewer symptoms of asthma, better pulmonary function, better exercise tolerance, and less requirements for corticosteroids than was treatment with metaproterenol.
