During 1974, eight of 37 (22%) Bordetella organisms isolated from patients in Cincinnate were Bordetella parapertussis. This is in contrast to other experience in the United States where parapertussis has comprised less than5% of the Bordetella species isolated and suggest that B parapertussis infection may be more common in this country than generally recognized. The failure to appreciate the presence of this infection may result from the lack of cultures taken from children with mild disease and the failure todistinguish B parapertussis from B pertussis. Ccultures were obtained from family members of three of the children with B parapertussis, and B pertussis was isolated from members of two families, including the mother and sister of a child who died of pneumonia and encephalopathy. These cases suggest that patients with severe disease associated with B parapertussis should be carefully evaluated for the possibility of dual infection caused by b pertussis.

During a pertussis epidemic, the majority of children admitted with respiratory disease were under one year old and had pneumonia, with or without pertussis syndrome; heart failure was common. A greater proportion of those with 'pneumonia alone' were slightly older, were malnourished, were admitted earlier and recovered slightly faster than those who had 'pertussis with pneumonia'. Differential white cell count was of little help in diagnosis and chest X-ray findings seldom altered management. Eight percent of the pertussis and 3 percent of the pneumonia groups died: all had pneumonia and additional complications, and 71 percent of those who died were under one year of age. Results suggest that two or more infections of triple antigen may protect some children from an attack of pertussis so severe that hospital care would be needed.

The patient records of 59 children aged 2--26 weeks with culture-verified pertussis were analysed. Twenty-four of them were hospitalized, in most cases for social reasons. Only one child with hypothyroidism and a complicating pneumonia was critically ill. Seventeen of the 35 non-hospitalized patients had a mild disease without developing typical whooping attacks. Thirteen children were treated with erythromycin in the catarrhal stage. There was a tendency towards milder disease in this group but the differences compared to untreated children were not statistically significant.

A high proportion of Cree and other North American Indian children have a chronic cough and many have bronchial wall thickening on radiographs, reminiscent of white children with asthma, mild cystic fibrosis, or immune deficiency. When compared to postmortem studies, radiographs underestimate the degree of bronchial wall thickening present. As compared to white children, Indian children in the first two years of life are more susceptible to recurrent bronchitis and pneumonia, are much more likely to develop pneumonia with rubeola and pertussis, and are more likely to develop chronic lung disease after adenovirus infections. Staphylococcal complications with pneumatocele formation are more common. A greater number acquire pneumonia while in hospital with other medical or surgical problems. Indian children with pneumonia recover more slowly, and some continue to deteriorate even after admission to hospital.

A clinical study of PC-904 was performed in children. The results were as follows; 1) Serum levels of PC-904 after single administration of 20 mg/kg were studied in patients by one-shot intravenous injection or drip infusion for 1 hour or 2 hours. The results obtained in this fundamental study led to the suggestion that the proper dosage in bacterial infections would be 50 approximately 100 mg/kg intravenously in 3 approximately 4 divided doses daily. 2) A clinical study of PC-904 was performed in 16 patients including acute pharyngitis and bronchitis (3 cases), acute bronchopneumonia (3 cases), pertussis pneumonia (1 case), lymphadenitis purulenta (2 cases), acute bronchopneumonia (3 cases), pertussis pneumonia (1 case), lymphadenitis purulenta (2 cases), abscess with chronic granuloma (2 cases) and urinary tract infection (5 cases). About 50 approximately 100 mg/kg of PC-904 were administered in 3 approximately 4 divided doses daily by one-shot intravenous injection. The clinical effects of 2 cases out of 16 were impossible to be evaluated, and thses cases were excluded from the clinical evaluation. Ten cases out of 14 showed excellent or good responses (efficacy rate: 71.4%). 3) The bacteriological examinations were performed and the causative or isolated organisms were determined in 11 cases. The responses were "disappeared" in 6 cases, "decreased" in 2 cases and "not disappeared" in 3 cases. 4) No side effects were observed. Abnormalities of laboratory findings were not also noticed.

From 1950 to 1970 in Hamburg, 9240 patients under 15 years of age were treated as inpatients for pertussis. 1674 patients had pneumonia due to pertussis, 114 had pertussis encephalopathies, and 41 seizures. The fatality from pneumonia went from 2,26% (1950-1960) to 0,4% (1961-1970). Fatality from encephalopathy was less influenced (24% respectively, 17,9%). The mild clinical course of pertussis is also reflected in the reduced number of hospitalizations due to pertussis (1956, 3,7%; 1970, 0,8%). Permanent damage from complications due to pertussis was seen in 0,7% of survivors from pertussis pneumonia and in 3,4% after pertussis encephalopathy.

Young dogs of two age groups, six weeks and 12 weeks respectively, were infected by aerosol with a strain of Bordetella bronchiseptica which had been isolated from a dog with pneumonia. Clinical respiratory disease characterised by coughing and in some cases purulent nasal discharge was induced in both groups of infected dogs and also in dogs kept in contact. B bronchiseptica was recovered from the nasal cavity, trachea, bronchi and lung parenchyma of infected and contact animals. At necropsy, masses of Gram-negative bacteria were found trapped in the cilia of the respiratory epithelia and there was an exudate containing neutrophils in the mucosae of the respiratory tract at all levels. A close similarity was noted between the lesions produced in the dog and those described in pertussis infection in man. Experimental respiratory disease in the dog due to B bronchiseptica may offer a model system for the study of the human disease.

Cefprozil (CFPZ, BMY-28100) is a new oral cephem antibiotic without an ester linkage. Pharmacokinetic and clinical studies using CFPZ 10% fine granules were performed in pediatric patients. 1. Pharmacokinetic investigation Peak serum concentrations of CFPZ after dose of 7.5 mg/kg and 10 mg/kg were, respectively, 3.65 +/- 0.24 micrograms/ml and 6.38 +/- 3.23 micrograms/ml at 1-2 hours. The average half-life with 7.5 mg/kg administration was 0.90 +/- 0.16 hours and that with 10 mg/kg was 1.29 +/- 0.50 hours. The urinary excretion of CFPZ was about 45% (35.3-50.0%) in 6 hours. 2. Clinical investigation Enrolled in the study were 22 patients including 4 with pharyngitis, 3 with tonsillitis, 3 with bronchitis, 5 with pneumonia, 4 with urinary tract infection, and 1 each with pertussis, purulent lymphadenitis and otitis media. Responses were excellent in 14 patients, good in 5 patients and fair in 1 patient. In the assessment of the bacteriological efficacy, 8 out of 17 strains of organism identified previous to the treatment were eradicated, 5 strains were found replaced by other bacteria and 4 strains persisted, hence the eradication rate was 76.5%. 3. No adverse reactions attributable to the drug were observed. From the above results, it has been concluded that CFPZ is a highly effective and safe agent for moderate respiratory and urinary tract infections in children.

The data accumulated within the last years required revision of the indications to the use of antibiotics in treatment of pertussis. One of the aims of antibiotic therapy in pertussis was to prevent colonization of B. pertussis in the respiratory tracts. With that end in view the choice of antibiotics should be limited by those, to which the pathogen is the most sensitive i.e. erythromycin, ampicillin and augmentin. Comparative efficacy of erythromycin and ampicillin during the first 2 weeks of the disease was studied in 79 infants at the age not older than 1 year with pertussis and it was shown that erythromycin was advantageous by its therapeutic activity and less side effects. Expedience of the antibiotic therapy during the spastic period for providing a preventive effect on development of bronchopulmonary complications was studied in 201 patients with pertussis. No preventive effect of the antibiotics on development of the bronchopulmonary complications defined by the secondary bacterial flora was recorded. In the group of the patients treated with the antibiotics prophylactically (group 1) the complications were 2.6 times more frequent than in the patients treated with pathogenetic agents alone (group 2). Intrahospital pneumonia developed in 8.9 per cent of the patients in group 1 and in 1.5 per cent of the patients in group 2. Therefore, antibiotics should not be used at the late periods of pertussis for prophylaxis of secondary bacterial complications.

There has been a noticeable increase in the incidence of pertussis in West Germany over the last decade. Since the availability of adequate bacteriological diagnosis a much broader clinical spectrum can be attributed to infections with B. pertussis. Three patients with an unusual clinical presentation of pertussis are presented. A three month old infant presented with severe apneic spells without cough as the sole clinical symptoms of the infection. B. pertussis was isolated in the nasopharyngeal swab. A nine month old premature infant with bronchopulmonary dysplasia after long time intubation and artificial ventilation presented with apneic spells, pulmonary and cardiac decompensation and required ventilatory support. The diagnosis was suggested by a massive leucocytosis with lymphocytosis. The diagnosis on the patient was established by serologic methods. Adult contacts of this patient developed longstanding cough and clinical signs of pertussis. The diagnosis of pertussis in these persons was established by nasopharyngeal culture. The third patient with trisomy 21 and a corrected AV canal suffered from nonspecific cough and gradually developed signs of congestive heart failure with pneumonia. B. pertussis was isolated from the nasopharynx. This patient showed neither the typical paroxysmal coughing spells nor disclosed the typical lymphocytosis in his white blood count. Microbiological investigations of patients with symptoms of respiratory tract infections should include the isolation of B. pertussis. Thus, additional cases of pertussis not suspected on the basis of their initial clinical presentation will be detected.
