Pharmacokinetic, bacteriological and clinical studies on SY5555 were performed in children. The results were as follows: 1. A total of 15 patients considered to have bacterial infections were treated with SY5555. Each dose, 5 mg/kg, was orally administered 3 times daily, for 4-11 days. Clinical efficacies of SY5555 in 13 patients with bacterial infections (1 with pneumonia, 2 with bronchitis, each 1 with maxillary sinusitis, 2 with otitis media, 5 with pharyngitis, 1 each with gastroenteritis and pyelonephritis) were evaluated as excellent in 10 patients and as good in 3 patients with an efficacy rate of 100%. Two patients with viral infection and malignant lymphoma were not evaluated. Thirteen causative strains in 7 species were found in 10 patients. Streptococcus pneumoniae in 1/3, Haemophilus influenzae in 2/2, Streptococcus pyogenes 4/4, Salmonella spp. in 1/1, Escherichia coli in 1/1 were eradicated. Only one patient developed mild diarrhea as an adverse reaction. Another patient showed elevated GPT (glutamate pyruvate transaminase). The abnormality was mild and the patient recovered after the cessation of SY5555 administration without specific treatment. 2. MICs of SY5555 were examined against 33 clinical isolates. SY5555 has low MICs against Enterococcus faecalis and other Gram-positive cocci. 3. Pharmacokinetic studies Peak plasma concentrations of SY5555 was 1.15 micrograms/ml at a dose level of 4.9 mg/kg orally administered at fasting. Based on the above results and the broad spectrum of the anti-bacterial activities, SY5555 appears to be a promising antibiotics that is usable as a single agent for the primary therapy of respiratory tract infections, skin soft tissue infections and urinary tract infections in children.

Five patients with AIDS had disseminated infection due to Septata intestinalis, a recently described organism. S. intestinalis infection was suspected after detection of spores in stools and urine and confirmed by transmission electron microscopy of duodenal biopsies or of cell culture of urine sediment. Clinical features included chronic diarrhea that was usually associated with fever, cholangitis, sinusitis, bronchitis, or mild bilateral conjunctivitis. Mean CD4 cell count was 22/microL. Patients treated with albendazole (400 mg orally twice a day) for a mean of 19 days had a dramatic and rapid clinical response to therapy. Significant reduction of parasite shedding was also observed during therapy; S. intestinalis was cleared from stools of all patients and from urine of 3. In 2 patients, however, microsporidian spores were detected in feces during follow-up and mild diarrhea recurred. Therefore, albendazole seems to have a significant but transient effect in treatment of S. intestinalis infection.

A prospective cohort study on 8124 schoolchildren aged 8 to 16 was conducted during the years 1977, 1979 and 1985 in Mannheim and two regions near Freiburg (Breisgau and the Black Forest). The objective of this part of the analysis was to investigate the regional differences in respiratory symptoms due to air pollution. Results are presented of 5726 children who had been living in those regions for at least five years at the times of interview. We have analysed 11 respiratory symptoms and two scores, measuring the tendency to infectious and asthmatic diseases, by logistic regression. Comparing the children living 1977 in Mannheim or the Breisgau to those living in the Black Forest the Relative Risks (Odds Ratios) of respiratory symptoms are in the range of 1.26-1.85 and 1.21-1.96 respectively. The results for the year 1979 are similar. In 1985 the regional effect has become smaller and no difference can be observed between Breisgau and the Black Forest. The infect score comprises bronchitis, inflamed throat with fever and sinusitis. The Relative Risk of an increased score decreases from 1.67 in 1977 to 1.65 in 1979 and 1.35 in 1985 in Mannheim and from 1.40 to 1.28 and 1.05 respectively in the Breisgau. The results of asthma and asthma symptoms are not homogeneous. In the Breisgau 1977 and 1979 the Relative Risk of an increased asthma score is slightly higher compared to the Black Forest. Allergies of the skin are reported more often in Mannheim than in the other areas. The Relative Risks of infectious respiratory symptoms and diseases agree spatially and temporarily well with the pattern of SO2 concentration. SO2 may be interpreted as an indicator for air pollution by power plants, industry and domestic heating.

This study was undertaken to characterize the epidemiology and clinical presentation of infection with Chlamydia pneumoniae in a population composed primarily of middle-aged and older adults. Pharyngeal swabs and acute and convalescent phase sera were obtained from outpatients presenting with signs and symptoms of an acute respiratory infection. Sera were examined using the micro-immunofluorescence (MIF) test to detect antibody to Chlamydia pneumoniae and complement fixation tests to detect Mycoplasma pneumoniae, influenza A virus, influenza B virus, respiratory syncytial virus and adenovirus. Pharyngeal swab specimens were cultured for Chlamydia pneumoniae and tested for Chlamydia pneumoniae by the polymerase chain reaction (PCR). A total of 743 patients with a mean age of 40.5 +/- 16.1 years were enrolled in the study. Twenty-one patients were serologically positive for acute Chlamydia pneumoniae infection in the MIF test. PCR was positive in 15 of the 20 serologically positive patients tested. Acute Chlamydia pneumoniae infection was identified in 3% (2/76) of subjects with pneumonia, 5% (12/247) of those with bronchitis, 5% (3/61) of those with sinusitis only and 2% (2/103) of those with pharyngitis only. Of the 21 patients with Chlamydia pneumoniae infection, seven (mean age of 33 years) had an antibody pattern suggesting a primary infection while 14 (mean age of 54 years) had a reinfection pattern. Patients with reinfection had milder disease than those with primary infection. PCR testing in the current study confirms the previously proposed serologic criteria of acute Chlamydia pneumoniae infection.

Chlamydia pneumoniae, also known as TWAR, is a common respiratory pathogen that can cause pneumonia, bronchitis, sinusitis, and pharyngitis. The clinical similarities between C pneumoniae infection and infection with other respiratory pathogens together with the lack, until recently, of readily available diagnostic tests for C pneumoniae have hindered its recognition and treatment in the outpatient setting. In this report, three patients with acute C pneumoniae infection from the Acute Respiratory Disease Study at the University of Washington are described, and the microbiologic characteristics, epidemiologic characteristics, clinical presentations, diagnosis, and treatment of acute C pneumoniae infection are considered.

Effects of indoor environmental factors on children's respiratory system and pulmonary function tests were investigated in this study. A total of 617 primary school children aged between 9-12 years were included. A standard questionnaire, which includes questions about respiratory symptoms and illness, indoor environmental determinants, family history of respiratory diseases, and smoking habits of the parents, was sent to homes of all children and information was obtained from parents. Children with a family history of asthma, bronchitis, or other chest troubles suffered morning and day/night coughs, shortness of breath, wheezing and asthma, bronchitis, or pneumonia more frequently. Children whose mothers smoked complained of blocked-runny nose and sinusitis more frequently. Pulmonary function levels were diminished in passive smokers and in children whose houses were heated by a wood-burning stove. As a result, passive smoking, using a wood-burning stove for heating, and family history of respiratory diseases are to be considered risk factors for the respiratory system.

A 7-year-old boy with recurrent otitis media, bronchitis, pneumonia, asthma, and sinusitis was found to have primary ciliary dyskinesia. It was important to rule out other systemic diseases such as immune deficiency and cystic fibrosis. Electron microscopy of a properly obtained and prepared biopsy of the mucosal surface of the nose, trachea, or bronchus is essential.

Southeast Washington State, which has a long history of seasonal dust storms, experienced 2 d of dust storms in October 1991, during which PM10 levels exceeded 1,000 micrograms/m3 (i.e., six times greater than the Environmental Protection Agency's 24-h PM10 standard). Three community hospitals in southeast Washington were visited for the purpose of assessing the possible effects of dust storms on respiratory health. During these visits, the number of emergency room visits for respiratory disorders for each day of 1991 were abstracted. These numbers were compared with daily PM10 levels for 1991. Also determined were the observed/expected ratios for the number of emergency room visits for each respiratory disorder category during October 1991. The maximum observed/expected ratio for the respiratory disorders was 1.2. For 1991, we found a 3.5% increase in the number of daily emergency room visits for bronchitis for each 100 micrograms/m3 increase in PM10. In addition, 2 d subsequent to those days on which the PM10 levels exceeded 150 micrograms/m3, there was a 4.5% increase in the number of emergency room visits for sinusitis for each 100 micrograms/m3 increase in PM10. Our results indicate that the naturally occurring PM10 in this setting has a small effect on the respiratory health of the population in general.

Respiratory infections are the most common infection in children. They differ remarkably according to age, bacteria and viruses. Therefore a careful history of outbreak, age, former infections, involvement of surroundings, symptoms, etc are essential. The present study included 50 children, aged between 0.3 and 12 yrs, all treated ambulatorily. 21 received brodimoprim (B) and 29 erythromycin (E). Indications were: tonsillitis, bronchitis, otitis media, sinusitis and scarlet fever. Dosages were: B was given 10 mg/kg body weight (b.w.) initially followed by 5 mg/kg b.w., once-a-day. The duration of treatment varied between 4 and 14 days (mean 8.3 days). E was given 30.50 mg/kg b.w. 3 times per day; duration 4 to 14 days (mean 8.6 days). Overall results were: in group B:12 cures, 5 improvements, 3 failures; 1 not assessable. In group E: 20 cures, 8 improvements, 1 failure. Side effects: in group B: vomiting (1), skin reaction (2), discontinuation (2); in group E: skin reaction (1), diarrhea (5), diarrhea+vomiting (1); discontinuation (2). The differences in efficacy and tolerability in the two groups are not statistically significant. The improved compliance with a single versus t.i.d. dosages has to be taken into account.

The existence of catharreal respiratory symptoms (such as pharyngitis, tracheitis, bronchitis etc.) is established as the usual manifestation of "exanthema subitum" due to acute human herpesvirus-6 (HHV-6) infection. But so far pneumonia, purulent sinusitis, purulent otitis media and/or acute obstructive bronchitis (bronchiolitis) in infants and children have not been described. Here we report the results of observations of 2 children with bronchopneumonia/sinusitis maxillaris and severe bronchiolitis associated with an acute HHV-6 infection. Other respiratory viruses were excluded as agents causing the ARD.
