We prospectively studied 10 previously healthy adults who developed an acute respiratory illness while working in an infants' ward during a community outbreak of respiratory syncytial virus infection. In addition to clinical and viral evaluation, total respiratory resistance before and after carbachol aerosol inhalation was measured. All 10 subjects had respiratory syncytial virus infection documented by viral isolation, and all developed pronounced cough, nasal congestion, and fever. Eight subjects missed work for an average of 6 days. In all 10 patients, the total respiratory resistance was significantly elevated through 8 weeks. Altered airway reactivity, characterized by exaggerated responses of pulmonary resistance to carbachol challenge, was also observed through the first 8 weeks of evaluation. In this group, respiratory syncytial virus produced a protracted illness associated with appreciable morbidity. The pathophysiologic mechanism of this illness in part appeared to arise from altered airway reactivity.

Thirty-eight workers from a factory producing nickel-cadmium and other types of batteries came to us for medical evaluation. They included 21 women and 17 men (seniority 2-20 years, age range 31-63 years), and represented a self-selected subset of 700-900 ever-employed and 200+ recently or currently employed workers in the factory. Thirty-four worked on the nickel-cadmium assembly line. Symptoms and signs included: headache in 34; weakness, fatigue and lassitude in 26; dizziness in 16; pruritus and skin eruptions in 37; gingivitis, teeth loss and caries in 34; nasal congestion, nosebleeds and anosmia in 30; cough, phlegm production, wheezing and shortness of breath in 26; "asthma" in 14; bone pain in 18; urinary frequency, beta 2 microglobulinuria and kidney stones in 17; and sterility or multiple abortions (33) in 8 of 21 women. One additional patient had died from an "amyotrophic lateral sclerosis-like syndrome", while CT scans in six workers revealed brain atrophy. One other worker had leukemia, and two had died from cancer (lung and pancreas). Those who had worked for more than 10 years had more symptoms and signs than shorter-term employees, especially neurological illness, bone pain and urinary tract problems, including beta 2 microglobulinuria. Past blood and urinary cadmium levels were in the range of 1.6-8.7 micrograms/dl and 8-306 micrograms/l, respectively. Our findings indicated that: a) health risks for workers were not confined to the nickel-cadmium assembly line or to older workers, b) hazardous exposures still existed and illness appeared in new workers after a clean-up and intervention program, and c) exposures involved increased risks for renal disease and cancers. Finally, there is a need to control exposures and determine health risks in the full cohort of those ever employed, in the workers' children, and in the surrounding environment (air, ground, water) due to the dumping of waste from the plant.

Respiratory disorders are common in children. Upper respiratory infection is particularly common in children who receive day care or group care. Frequently used methods of treating the common cold (eg, heated vapor, over-the-counter antihistamines and decongestants) have not been proven objectively to be beneficial in young children. Sinusitis is usually diagnosed through history taking (eg, complaints of more than 9 days of non-improving nasal congestion and/or cough), but radiographs may be necessary. Antibiotics effective against specific causative agents are the treatment of choice. Data do not support routine use of myringotomy to treat acute otitis media, but combined with tube placement, this method is useful for recurrent infection. Antibiotic prophylaxis may help prevent recurrent episodes of acute otitis media. Before tonsillectomy is considered for pharyngitis, a history of recurrent episodes must be documented. Epiglottitis, although increasingly rare, should still be considered when certain specific clinical signs are present.

Some patients report rhinitis symptoms after exposure to environmental tobacco smoke (ETS), but objective assessments of this response have been lacking. Furthermore, the mechanism of this response is unknown. We assessed the frequency of ETS-related symptoms by administering a questionnaire to 77 healthy nonsmoking young adults who were participating in an unrelated study. Of the subjects 34% (26 of 77) reported one or more rhinitis symptoms (congestion, rhinorrhea, or sneezing) following ETS exposure. We then exposed 10 historically ETS-sensitive (ETS-S) and 11 historically ETS-nonsensitive (ETS-NS) subjects to 15 min of clean air followed by 15 min of sidestream tobacco smoke (CO concentration of 45 parts per million). At selected time points during these procedures we recorded symptoms, posterior nasal resistance, and spirometry and performed nasal lavages. ETS-S but not ETS-NS subjects reported significant (p less than 0.01) increases in nasal congestion, headache, chest discomfort or tightness, and cough following exposure to sidestream tobacco smoke. Rhinorrhea symptoms were greater and more prolonged in ETS-S subjects compared to ETS-NS subjects. Significant (p less than 0.01) increases in perception of odor and in eye, nose, and throat irritation occurred in both study groups, but ETS-S subjects reported significantly more nose and throat irritation. No significant changes in posterior nasal resistance occurred in the ETS-NS group but a significant increase occurred in the ETS-S subjects, with the resistance rising from 3.8 +/- 0.5 cm H2O/L/s (mean +/- SE) preexposure to a peak of 8.0 +/- 2.7 cm H2O/L/s 20 min after completion of the smoke exposure (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Human parainfluenza type 3 is the most common cause of bronchiolitis and pneumonia after respiratory syncytial virus. In a recent outbreak of nosocomial respiratory illness in a neonatal intensive care unit, parainfluenza type 3 virus was isolated in 6 of 17 neonates cultured (5 symptomatic patients and 1 asymptomatic patient). Eighteen of 52 nursing personnel had been ill during the previous week and concomitantly, with cough and nasal congestion. These personnel and all patient care givers were asked to submit nasopharyngeal cultures. Parainfluenza type 3 virus was recovered from 2. Glove and gown barriers and cohorting of infant patients limited further spread of the disease.

CT-scan was used to examine rhinosinusitis in the developing sinuses; 196 children aged from 3 to 14 years were selected on the base of their chronic rhinorrhea, nasal congestion and cough. The patients were subdivided into six age groups (3-4, 5-6, 7-8, 9-10, 11-12 and 13-14 years). In the youngest age group, the authors noted maxillary involvement in 63%, ethmoidal involvement in 58%, and even sphenoidal sinus involvement in 29% of the children. Involvement decreased gradually with age, with 10% of ethmoidal and 0% of sphenoidal involvement in the 13-14 years age group. Maxillary sinusitis, however, persisted very frequently in the oldest age group (65%). Frontal involvement seems to become significant at the age of 7-8 years (7%) but it never exceeds 15% (11-12 age group). Septal deviations occurred in 16% of the youngest up to 72% in the oldest age group. The prevalence of bullous conchae increased with age too, although less prominently.

Respiratory syncytial viral infection is the leading cause of acute lower respiratory tract disease in infants and young children. Presenting symptoms include rhinorrhea, nasal congestion, a low grade fever, and a cough. Hypoxemia and respiratory acidosis are the most common presentation for infants requiring intensive care. Critical care nurses must skillfully assess the infant's clinical status and response to medical treatment, implement and enforce isolation procedures, and remain sensitive to the emotional and psychologic needs of RSV-infected infants and their families. They must be knowledgeable regarding the latest research and recommendations concerning isolation policies and safe administration of ribavirin therapy in order to maximize the care for infants experiencing acute respiratory distress caused by RSV infection.

A principal side effect of biological response modifiers (BRMs) is a constellation of constitutional symptoms often referred to as a "flu-like syndrome" (FLS). Precisely what this syndrome encompasses is frequently unclear, but its major components appear to be fever, chills, rigors, myalgias, and headache. Other components variously included are anorexia, nausea, upper respiratory symptoms such as nasal congestion and cough, and the ill-defined symptom, malaise. The manner in which the "flu-like" syndrome manifests itself during treatment with interferon (IFN), interleukin-2 (IL-2), tumor necrosis factor (TNF), monoclonal antibodies (MoAbs), and colony stimulating factors (CSFs) will be described with attention to frequency, duration and severity. The common mechanisms underlying the appearance of a flu-like syndrome during biotherapy will be elucidated with emphasis on the role of endogenous pyrogens and prostaglandins and on the physiology of the process. Methods to prevent or alleviate these uncomfortable side effects, including medical interventions such as alterations in schedule/route/dose of BRM administration and premedication with a variety of agents, as well as nursing measures such as patient education will be discussed.

One of the most important characteristics of asthma is its association with non specific bronchial hyperresponsiveness. This is diagnosed by histamine bronchial challenge tests. This latter is an easy procedure but requires a precise and standardized methodology. We have analysed, in a large group of bronchial challenge tests (n = 162) the clinical correlations with bronchial response to histamine. Our conclusions are in agreement with several recent literature, and may be summarised as follows: 1. more than 10% of patients, clinically considered as asthmatics do not show bronchial hyperresponsiveness and probably will not benefit from bronchodilators; 2. several aspecific respiratory symptoms (cough, chest tightness, blocked nose and sneezing, recurrent bronchitis, etc...) are frequently associated with bronchial hyperresponsiveness and should be considered as asthmatic manifestations. To conclude, we recommend to realise a histamine non specific challenge test in all cases of clinical suspicion of asthma (with normal lung function at basal state) and in all subjects presenting chest symptoms of uncertain etiology.
