Eight young thoroughbred horses, taken 1858 km by road (travelling time, 41 h), were examined to assess the pathological nature of respiratory disease associated with transport. Three of the horses showed clinical abnormalities including pyrexia, coughing, leucocytosis and neutrophilia after the first 20 h of transportation. Endoscopical examination of the trachea revealed exacerbation of airway inflammation as a result of transport in two of the three affected horses. A consistent finding in the affected horses was focal serous neutrophilic pneumonia affecting the cranio-ventral portion of the caudal lung lobe with a propensity to affect the right lung. Streptococcus equi subspecies zooepidemicus was isolated from the pneumonic areas, in which corresponding bacterial antigens were identified immunohistochemically. Viral cultures from the pneumonic lesions proved negative for respiratory viruses. It is suggested that transport predisposes the upper respiratory tract and the lower airways to invasion by the bacterium, with episodic pyrexia and acute pneumonia.

We examined an endogenous substance causing cough in awake guinea pigs. An intraperitoneal injection of phosphoramidon, a selective inhibitor of neutral endopeptidase (E.C. 3.4.24.11), caused cough in a dose-dependent fashion for approximately 40 min. At a dose of 3 x 10(-3) mol/kg, phosphoramidon caused a total of 11.6 +/- 1.4 coughs in 40 min. Phosphoramidon (3 x 10(-3) mol/kg)-induced cough was significantly inhibited by systemic pretreatment with capsaicin (p < 0.01). Aerosols of FK 888 (1 min), a specific inhibitor of substance P (NK1) receptor, inhibited phosphoramidon (3 x 10(-3) mol/kg)-induced cough in a dose-dependent fashion with complete inhibition at a dose of 10(-5) M. Likewise, aerosols of FK 224 (10(-5) M; 1 min), another inhibitor of NK1 and NK2 receptors, or lidocaine (4%, 1 min) significantly inhibited phosphoramidon (3 x 10(-3) mol/kg)-induced cough (p < 0.01). Furthermore, aerosols of FK 888 (10(-5) M; 1 min) significantly inhibited cough induced by cigarette smoke in awake guinea pigs (p < 0.01). These results suggest that substance P released from sensory nerves in the airway may be an endogenous substance causing cough and the substance P antagonist may be the drug for treatment of cough in respiratory disease.

Respiratory patients require psychotropic drug administration to treat pain, cough and respiratory distress or to treat insomnia, anxiety, depression or psychosis. Terminal patients require thoughtful and compassionate use of these drugs, even when there is an expectation that such therapy may lead to an earlier death. Most psychotropic agents can be used safely in patients with respiratory disease, and careful use of selected drugs should always be employed if indicated for treating distressful conditions that may be benefitted. Guidelines to appropriate choices and doses are provided.

A double blind randomized clinical trial was performed with pigs suffering from clinical respiratory disease. The goal of the trial was to test the null hypothesis that the clinical recovery after treatment with two oxytetracycline injectables with different pharmacokinetic profiles (high peak concentration and low persistence versus low peak concentrations and long persistence) was similar. Fattening pigs (n = 529) were treated intramuscularly with either product A or product B at a dose of 20 mg OTC per kg b.w. when they showed signs of acute pneumonia, i.e., coughing, tachypnoea or dyspnoea combined with a rectal temperature of 40 degrees C or higher. When necessary, treatment was given again after 3 and/or 6 days. Both treatments resulted in a rapid fall in mean temperature and an improved clinical condition. In this trial no significant differences were found in clinical recovery between the two therapies as measured by group mean temperature, number of pigs requiring retreatment, and time to recovery. The conclusion that there was no important difference in clinical recovery between the treatment groups was made with a power of at least 90%.

Lower respiratory disease is a major source of morbidity in military recruits, with hospitalization rates for pneumonia more than 30 times that of the non-recruit population. The etiologic agent remains unknown in over 75% of cases. This study prospectively examined the etiology of pneumonia among recruits at Naval Training Center, San Diego, California. Recruits presenting with cough, fever, or shortness of breath and pulmonary infiltrates on chest X-ray were eligible for enrollment. A standardized scoring form and focused physical exam were completed on each subject. Sputum specimens were obtained for Gram's stain and culture, DNA probing for Legionella and Mycoplasma species, and direct fluorescent antibody staining for Legionella. Acute and convalescent serologies were performed for adenovirus, influenza A and B, Mycoplasma pneumoniae, Chlamydia group, and respiratory syncytial virus. Of 110 eligible patients, 100 consented to enrollment and 75 patients completed the study. Etiologic diagnoses were obtained in 40 of the patients (53%). M. pneumoniae, Haemophilus influenzae, and viruses accounted for the majority of infections. Mixed infections were seen in six patients. Forty-seven percent of patients had no diagnosis established. Pneumonia in this series of military recruits was frequently caused by M. pneumoniae and H. influenzae. Fifty percent of cases were undiagnosed with routinely available laboratory methods. Further studies are warranted to more clearly define the etiologic agents of recruit pneumonia and the utility of prophylactic measures.

Tuberculosis and human immunodeficiency virus (HIV) infection are two important linked public health problems in the world of today. Tuberculosis in HIV infected patients is frequently atypical in its clinical and radiological findings and commonly has an extrapulmonary dissemination. Atypical mycobacteriosis have also been reported in patients with HIV infection. We review here all the patients admitted from 1986 to 1991 with definitive diagnosis of tuberculosis and HIV infection at the National Institute of Respiratory Diseases in Mexico City. Out of 220 patients with HIV infection and pulmonary complications, 19 had proven tuberculosis. Their mean age was 34 +/- 8 years and seven were homosexual males. In 16 patients (84%), respiratory symptoms (cough with sputum) and fever were the first manifestations of the HIV infection. Only two patients had the typical cavitary lesions but also coexisting with miliary tuberculosis. The rest had several types of non cavitated pulmonary opacities or other thoracic or pleural alterations. Eleven patients (58%) had, in addition, extrapulmonary tuberculosis. Mycobacterium tuberculosis was cultured in 11 of 12 patients but no atypical mycobacteria were isolated. Only seven of the 19 patients completed at least six months of treatment and two of them relapsed. Three patients died in their first admission; the rest were lost in the follow up. Our results show that the clinical features of tuberculosis associated to HIV infection are similar to those described in other countries.

An open study to assess the efficacy and safety of 50 micrograms inhaled Salmeterol (Serevent) administered twice daily as maintenance therapy for asthma was undertaken by the Respiratory Diseases Research Unit (RDRU) in Nairobi between August and October, 1992. Salmeterol (Hydroxynaphthoate) is a long acting selective beta-2-agonist. Seventy-three adult patients recruited at Kenyatta National Hospital underwent a two weeks treatment period during which they were assessed over three visits. At Visit 1, eligibility was confirmed, baseline lung function indices measured, the study drug introduced and all the previous medications withdrawn. After treatment for one week (Visit 2) and two weeks (Visit 3), lung function indices were measured again and subjective patients' and physicians' assessments of efficacy documented. Patients with obstructive ventilatory defect (OVD) at baseline had significant improvement in their lung function compared to those without at the end of the treatment period. A significant number of patients reported decreased number of nocturnal awakenings and increased tolerance to physical activity. Cough, headache and itchy throat were adverse events possibly related to the use of Salmeterol. The patients treated with Salmeterol gained improved control of their asthma symptoms. The drug offers a convenient dose schedule and we recommend its use for maintenance therapy for mild to moderate asthma.

Gastroesophageal reflux (GER) in infants is most commonly thought of as repeated excessive vomiting and failure to thrive, with most infants responding favorably to medical therapy. However, GER may also manifest exclusively with a variety of respiratory symptoms that, if not detected and treated early, may lead to life-threatening complications. During the period of 1987 to 1992, 39 neonates and infants underwent Nissen fundoplication for the treatment of respiratory symptoms attributed to GER. Symptoms included apnea and bradycardia (64%), pneumonia (31%), cyanosis (28%), cough (18%), and stridor (15%). Most patients were ascribed at least one incorrect diagnosis to explain respiratory symptoms. These include apnea of prematurity (38%), bronchopulmonary dysplasia (31%), asthma (8%), and subglottic stenosis (8%). All patients underwent a variety of investigations and medical treatments without noticeable clinical improvement. These included bronchoscopy, esophagoscopy, and polysomnograms. Treatment such as antibiotics, theophylline, bronchodilators, steroids, and oxygen were directed at presumed primary respiratory disease. On the other hand, H2 blockers, metoclopramide, positioning, and thickened feeds were prescribed to treat GER without objective evidence of disease. Ultimately, GER was demonstrated by upper gastrointestinal series in 64%, pH probe in 61%, and both studies in 38%. All patients underwent Nissen fundoplication after failed attempts at medical therapy. A total of 95% of patients had resolution or substantial improvement of respiratory symptoms postoperatively. Preoperative hospitalization averaged 37.0 days, and postoperative stay averaged only 14.2 days. We present a series of patients with GER, all of whom presented with respiratory symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)

Infectious laryngotracheitis (ILT) was diagnosed as the cause of an outbreak of respiratory disease in broiler chickens in California. The classical form of ILT is characterized by dyspnea, gasping, coughing, and expectoration of bloody exudate. Most of the broilers submitted to the diagnostic laboratory showed a non-classical presentation of ILT, in which mucoid tracheitis and conjunctivitis were the most consistent lesions. Historically, most of the ILT cases diagnosed in our laboratory have consisted of layers with classical signs and lesions. It is not known whether this non classical presentation of ILT in broilers is due to differences in the way broilers respond to ILT infection or to the nature of the ILT virus isolate.

As part of a 1992 survey of both environmental and occupational determinants of health, 973 non-smoking women aged 20-40 years who were employed in three comparable modern Chinese cotton textile mills were given a questionnaire that included questions on standard respiratory history and symptoms. All women had some potential exposure to cotton dust; mean employment was 8.7 years. Comparisons were made between those with lowest or no current exposure (job classification in administration, quality control, and testing, n = 112) and those in the more heavily exposed classifications (yarn production areas, n = 861). Association of symptoms with job was tested by logistic regression, adjusting for age, passive smoking at home, and the use of home coal burning stoves. Odds ratios for prevalence of current frequent symptoms in those working in production jobs, after adjustment for home exposure to passive tobacco smoke and coal heating, were frequent cough 2.23 (95% confidence interval (95% CI) 1.05-4.75), frequent phlegm 3.24 (1.54-6.84), shortness of breath 4.54 (1.40-14.72), and wheeze 2.96 (1.16-7.55). Nine cases with grade I byssinosis (chest tightness or shortness of breath on return to work after two days off) were found; all were in production jobs. In these non-smoking women textile workers, chronic respiratory symptoms were associated with job category after correction for domestic indoor air quality. These data support evidence for an increased prevalence of respiratory disease in populations exposed to cotton dust.
