In 80 patients with Pneumocystis pneumonitis, the intial signs and symptoms of infection were usually fever and cough, followed by tachypnea and coryza. Flaring of the nasal alae and cyanosis occurred later. Blood gas composition was markedly altered in its acid-base profile in most patients at admission. There was moderate to severe respiratory alkalosis and hypoxia. Clinical manifestations were correlated with the extent of histopathologic changes in the lung. (Deprivation of protein in the diet of rats provoked P. carinii infection.) P. carinii infection was found in children with kwashiorkor; evidence of protein-calorie malnutrition is closely associated with P. carinii pneumonitis in children wiht cancer and other primary diseases. P. carinii pneumonitis proved unique in that the causative organisms remained limited to the lungs even in fatal cases. No toxins have been identified, and systemic effects of the infection were only those that could be related to hypoxia and fever.

Seven patients, aged 12 to 19 years, had atypical measles. Prodromal symptoms of fever, malaise, myalgia, headache, nausea, and vomiting were commonly followed by coryza, sore throat, conjunctivitis, photophobia, nonproductive cough, and pleuritic pain. The characteristic rash was erythematous, maculopapular, and progressed frequently to vesicular, petechial, or purpuric lesions. It initially involved palms and soles with subsequent spread to proximal extremities and the trunk, sparing the face. Six of six chest roentgenograms showed infiltrates. Findings not previously described in atypical measles included liver enzyme elevations, thrombocytopenia, disseminated intravascular coagulation, possible transmission among three siblings, and suspected cardiac involvement. Measles complement fixation titers compatible with recent infection were seen in all patients. All patients had previously received killed measles vaccine. A substantial number of persons who are older adolescents or young adults may be at risk of developing atypical measles.

73 welders were examined, who weld in an assembly room of a machine factory, mainly by an electric arc. In anamneses 60% of persons under examination notified of coughing, expectorating, dyspnoea during work, and frequent acute rhinitis. Clinical symptoms of respiratory tract disease, resulting from welding, were found in 10% of welders. Simple bronchitis, resistant bronchitis with pulmonary emphysema, pleural adhesions were diagnosed. In one case fibronodular tuberculosis was found (1%). In 8% of workers, aged 40--50, a dynamic arterial hypertension and radiological symptoms of aortosclerosis were found. 5% welders had granulocytopenia. Disturbances of the examined systems occurred in factory welders with duration of employment above 10 years.

Squirrel monkeys (Saimiri sciureus) inoculated intratracheally with 10(4.2)-10(8.2) egg median infectious doses (EID50) of type A influenza virus (H3N2) responded with clinical illness including such signs as fever, sneezing or coughing, coryza, and increased respiratory rates. Necropsy studies performed six days after inoculation revealed bronchopneumonia in addition to a mild tracheitis. Squirrel monkeys given 10(5)-6 x 10(8) colony-forming units (cfu) of Streptococcus pneumoniae intratracheally died four to six days later after developing severe illness characterized by fever, bacteremia, lethargy, anorexia, coughing, labored breathing, and bronchopneumonia. Monkeys given 770 cfu of S. pneumoniae responded with less severe symptoms and survived. Four squirrel monkeys inoculated with 10(8.2) EID50 of virus and then 102 hr later with 770 cfu of S. pneumoniae developed severe disease; three of the four animals died within 40 hr. At necropsy these monkeys had more extensive and severe bronchopneumonia than was seen in monkeys infected with either organism alone.

The progeny of 9 SPF gilts fed a balanced ration (Table I) was used in an inoculation experiment with field strains of Bordetella bronchiseptica isolated in herds suffering atrophic rhinitis. Acute rhinitis was produced within a week after intranasal inoculation of B. bronchiseptica into 1 to 11-day-old piglets. Coughing occurred in some of the exposed pigs, but signs of pneumonia did not develop. A few pigs were killed at intervals of 1 to 3 weeks after exposure. These pigs all showed histological lesions in the turbinate and B. bronchiseptica was recovered from various parts of the respiratory tract. Pigs killed 3 weeks after inoculation showed advanced turbinate atrophy (Tables II and III). Among inoculated litter mates reared to slaughter weight, only one developed clinical signs (slight) of atrophic rhinitis, and a tendency towards an elimination of the B. bronchiseptica infection from the accessible part of the nasal cavity was noticed during the growth period. By examination of nasal swabs collected when the pigs were 10 to 13 weeks old, Mycoplasma flocculare was isolated as well from pigs inoculated with B. bronchiseptica as from the control pigs. The growth rate of the experimental pigs was high and no difference in feed consumption or feed conversion occurred between the exposed pigs and the control pigs. By post mortem examination of the snouts from the pigs slaughtered at approx. 85 kg live weight, severe atrophic rhinitis was not found. Approximately one third (32%) of the exposed pigs showed slight atrophic rhinitis lesions (Table IV). The results are discussed and it is concluded that the isolated B. bronchiseptica strains are pathogenic in young pigs and able to induce turbinate atrophy 2 to 3 weeks after inoculation. Turbinate atrophy induced in pigs a few weeks old, may apparently restore completely or almost completely during the growth period. Under the provided experimental conditions, infection with B. bronchiseptica did not result in the development of a lasting, growth-retarding atrophic rhinitis.

The indirect hemagglutination (IHA) test for coronavirus 229E antibodies was used for serodiagnostic and seroepidemiologic studies in a population of children. Subjects ranged in age from 5 to 19 years and lived in a home which participated in a longitudinal surveilance of respiratory illness (1960-1968). During this period 1477 respiratory illnesses were observed; 63 (4%) were associated with sero-response (fourfold or greater antibody rises) to 229E. An additional 105 sero-responses were associated with unreported or subclinical illness. The frequency of these infections was cyclical, and 229E and coronavirus OC 43 infections peaked in different years among the same population. Sero-responses occurred mainly in the fall, winter and spring quarters. Preexisting antibody was demonstrated in one-third of the children with 229E sero-responses. Clinical studies indicated that the most frequent complaints with 229E infections were sore throat, coryza and cough, and the most frequent findings were pharyngeal injection, coryza and fever.

Systematic monitoring of infants and children in a day-care center revealed infection with Mycoplasma pneumoniae to be more common than expected. Most of these infections were asymptomatic (74%) or associated with mild, nonspecific coryza and cough. Infected children ranged in age from 2 months to 8 years. Complement-fixing and growth-inhibiting antibodies in serum tended to wane rapidly and reinfection was detected in five children after one and one-half to 3 years. In vitro lymphocyte studies revealed antigen-reactive cells were detectable in few of the children under age 4, but thereafter lymphocyte reactivity was found in 53%. These findings suggest that recurrent, unsuspected M. pneumoniae infections occur during infancy and early childhood and that pneumonic disease, common above age 10 years, is an expression of increasing host immune response to the organism.

In immunocompetent patients, infection by the measles (rubeola) paramyxovirus produces fever, cough, coryza, Koplik's spots, and, on the skin, a macular erythema that can become confluent. The erythema has a striking cephalocaudal spread and clearing. The diagnosis of measles on a skin biopsy and the distinction from an erythema multiforme type of drug eruption can be difficult. We studied a skin biopsy from a patient with the acquired immunodeficiency syndrome (AIDS) who presented with measles. In contrast to erythema multiforme, the measles biopsy has necrosis of clusters of keratinocytes in the high spinous layer and granular layer of the epidermis, whereas erythema multiforme has necrosis of basal keratinocytes. Multinucleated keratinocytes may or may not be prominent in the measles biopsy. Cytoplasmic swelling of the keratinocytes in the granular layer may be present even when multinucleated cells are sparse. Immunoperoxidase reactivity for measles virus protein is present in intranuclear inclusions and in the cytoplasm of infected upper spinous keratinocytes. There were more cells with positive staining in the biopsy from the AIDS patient than in another biopsy from an immunocompetent patient with measles. The AIDS patient was seronegative for measles throughout the course of the illness. The examination of the skin biopsy can be very important in the diagnosis of measles in AIDS patients or immunocompromised patients who may not develop the usual diagnostic serology.

A prospective evaluation was made of an algorithm for a selective use of throat swabs in patients with sore throat in general practice. The algorithm states that a throat swab should be obtained (a) in all children younger than 15 years; (b) in patients aged 15 years or more who have pain on swallowing and at least three of four signs (enlarged or hyperaemic tonsils; exudate; enlarged or tender angular lymph nodes; and a temperature > or = 38 degrees C); and (c) in adults aged 15-44 years with pain on swallowing and one or two of the four signs, but not both cough and coryza. Group A streptococci were found by laboratory culture in 30% of throat swabs from 1783 patients. Using these results as the reference, the algorithm was 95% sensitive and 26% specific, and assigned 80% of the patients to be swabbed. Its positive and negative predictive values in this setting were 36% and 92%, respectively. It is concluded that this algorithm may be useful in general practice.

A retrospective analysis was completed of the charts of the 1,727 patients with the diagnosis of croup seen during two years (1985 and 1986) in the Emergency Department of The Hospital for Sick Children in Toronto. Cough (91.4%) was the most common presenting symptom. Other presenting signs and symptoms included stridor (57.5%), chest wall retraction (38%), coryza and wheezing (18.5%) and tracheal tug (15%). The majority of patients were treated on an ambulatory basis while 377 (21.7%) were admitted for further management. Inpatient treatment included racemic epinephrine (120 patients) and parenteral steroids (17). Twelve (12) patients required airway support (endotracheal intubation). No tracheotomy for tracheitis was performed during this two year period. No deaths occurred in this patient population.
