Following immunization, peak geometric mean serum metabolism inhibition antibody (MIT) titres were 1:13 and 1:16 for groups of three chimpanzees each that received either the formalin-inactivated OSU-1A or experimental acellular extract vaccine, respectively. Following challenge, the mean titres for chimpanzees given the acellular vaccine peaked at 1:256 in 4 weeks and was 1:48 at 10 weeks. Chimpanzees given the OSU-1A vaccine peaked at 1:80 in 4 weeks and remained at 1:80 at 10 weeks. There was no direct correlation between the serum MIT response and the severity of disease or colonization, and thus the MIT response was not a reliable measurement of protection. The two non-immunized chimpanzees showed significant signs of disease, including cough, pharyngitis, rhinitis, fever and abnormal X-ray findings, for about 5 weeks. The chimpanzees immunized with either vaccine were less colonized and showed far less disease than non-immunized controls. Protection afforded the chimpanzees was similar to that of vaccinees in the human clinical trial given the same OSU-1A vaccine (Wenzel et al., 1977). The two previously infected chimpanzees were most protected against colonization and disease on challenge.

Consecutive weekly or biweekly serum specimens obtained during a 3- or 4-month study from 16 chimpanzees were examined by immunoblot analyses to identify the immunogenic components of Mycoplasma pneumoniae. Six experimentally infected chimpanzees showed significant signs of overt disease, including cough, pharyngitis, rhinitis, fever, and loss of appetite. The sera of these infected chimpanzees recognized from 17 to 20 protein bands. Two control chimpanzees that were not inoculated were included in the study. Three chimpanzees immunized with a formalin-inactivated OSU-1A vaccine and three chimpanzees immunized with an experimental acellular vaccine showed minimal signs of disease on challenge. After challenge, the serum immunoblot responses of the immunized chimpanzees were similar to those of the infected chimpanzees. Before challenge, the sera of two previously infected chimpanzees recognized protein bands of 169 (which comigrated with the P1 adhesin), 148, 130, 117, 86, 61, 44, 35, 30, and 29 kDa. After challenge, the previously infected chimpanzees showed the most intense serum immunoblot responses and were most protected against colonization and disease. The sera from each of the 16 chimpanzees examined recognized a large number of immunogenic components, and the serum immunoblot responses were virtually identical to those of patients. Sera from each chimpanzee and patient recognized 169-, 148-, 130-, 117-, 86-, 44-, and 35-kDa bands and many of them recognized 67-, 63-, 61-, 56-, 32-, 30-, and 29-kDa protein bands.

Chlamydia pneumoniae has recently been shown to be a cause of pharyngitis. Because the impact of this pathogen on United States Air Force basic trainees is unknown, the authors undertook a prospective study to evaluate the prevalence of C pneumoniae. Of 118 asymptomatic basic trainees, 43% had preexisting antibodies to C pneumoniae and 0.9% had serologic evidence of C pneumoniae infection. Of 226 symptomatic basic trainees, only four (1.8%) met the criteria for serologic evidence of acute C pneumoniae infection. No other cause of pharyngitis was found in three of four of these basic trainees. Three of the trainees with C pneumoniae infection had hoarseness and all had a dry cough. All symptoms resolved without specific antichlamydial therapy. Chlamydia pneumoniae was an uncommon cause of pharyngitis in basic trainees, appearing as a mild, self-limiting illness.

Moraxella catarrhalis and Hemophilus influenzae are isolated from the nasopharynx in 50% to 55% and 8% to 15%, respectively, of cases of acute laryngitis in adults. This finding indicates that these organisms, M catarrhalis in particular, are in some way involved in the pathogenesis of the disorder. In the present double-blind, placebo-controlled trial, the effect of erythromycin ethylsuccinate (0.5 g twice a day for 5 days) on the elimination of nasopharyngeal pathogens and reduction of clinical signs of upper respiratory tract infection, as well as on subjective complaints, was evaluated in 106 adults with acute laryngitis. The bacterial isolation rates at presentation were M catarrhalis 50%, H influenzae 18%, and Streptococcus pneumoniae 4%. In the 99 patients who completed the study, the elimination of M catarrhalis after 1 week was better in the erythromycin group (25 of 30 cases) than in the placebo group (6 of 19 cases; p < or = .00038). The elimination of H influenzae was unaffected by erythromycin. Otolaryngologic examination did not reveal any significant group differences regarding laryngitis, pharyngitis, or rhinitis. Voice quality was improved after 1 week, irrespective of treatment. However, as compared to the placebo group, the erythromycin group reported fewer voice complaints after 1 week and fewer coughing complaints after 2 weeks. As acute laryngitis in adults is self-limiting, and subjective symptoms are spontaneously reduced after 1 week in most cases, antibiotic treatment does not seem warranted as a general policy. However, erythromycin may be justified in patients who are professionally dependent on voice function.

To obtain accurate data on the incidence and clinical profile of acute respiratory infections (ARI) in Egyptian infants and children aged 4 years and under, 115 randomly selected health centers in five of the country's 26 governorates participated in an ARI Case Registration System. Each month during 1993, specially trained physicians assigned to the project submitted a case diagnosis form. The survey yielded a total of 75,789 records representing seven categories: very severe disease (0.9%); severe pneumonia (2.9%); pneumonia (9.9%); otitis media (10.7%); pharyngitis (22.8%); asthma (4.8%); and cough, cold, and bronchitis (48.1%). 4.1% of patients were under 2 months old, 29.9% were 2-11 months of age, and 66.0% were 1-4 years old. Pneumonia cases peaked in January and fell off in June. When the reliability of disease symptoms as reported by caretakers was compared to the corresponding clinical signs observed by physicians, specificity was in the 95-97% range, but sensitivity was extremely low (e.g., 48-59% for rapid breathing). This analysis enabled health centers to calculate the annual drug requirements for use in ARI. For example, the finding that 34% of ARI cases involve children under 12 months of age led to a decision to ensure that one-third of the amoxycillin ordered for use in the clinics is of the 125 mg strength.

Chronic Cough: Chronic persistent cough (CPC) lasting from several months to years - without radiographic or spirometric evidence of its cause - was a surprisingly frequent reason (5,7% of all new referrals) to consult our practice. Sophisticated diagnostic evaluation and therapeutic regimen are necessary. We performed a prospective study on 329 consecutive patients (106 male, 223 female) over a two-year period. 65% of the patients had cough as a consequence of bronchial hyperresponsiveness; 27% due to upper airways disease, i.e. often very common rhinitis or pharyngitis; 14% chronic bronchitis; 5% gastrooesophageal reflux (GER); 3% drug induced cough; 4% other causes. 10% of the patients discontinued the diagnostic evaluation prematurely. In 14% the cause for CPC remained unclear and no relief could be achieved. Furthermore, there is a need for consecutive studies to address the following questions: 1. The cause of the striking difference in gender (male : female = 1 : 2) remains unclear. 2. Wether a cough recorder - as occasionally reported in the literature - is needed for an objective evaluation of cough [9]. 3. A standardised methodology of 24 h pH monitoring for the diagnosis of CPC as a consequence of GER has yet to be established.

1. The use of tear gas to control civil unrest is accepted practice by government authorities worldwide. It is rarely used in Hong Kong but during a recent riot at a Vietnamese detention centre large quantities were used and this was cause for some concern. 2. All patients presenting to the British Red Cross Clinic after the incident were seen by one of the authors. To establish if exposure to tear gas had serious effects on the health of the detainees, the case records of the 184 patients with symptoms consistent with CS exposure were reviewed 2 months later. 3. The most common complaints were burns (52%), cough (38%), headache (29%), shortness of breath (21%), chest pain (19%), sore throat (15%) and fever (13%). However, the only common findings on examination by a physician were burns (52%) and an inflamed throat (27%). All burns could be categorised as "minor' according to the American Burns Association classification and all were consistent with CS gas exposure. 4. Some patients complained of other symptoms that had not been previously reported in the literature, such as haemoptysis (8%) and haematemesis (4%), but these were only confirmed in one patient. 5. The majority of patients had recovered within 2 weeks of exposure although one asthmatic patient complained of shortness of breath lasting for 33 days and a sore throat lasting for 38 days after the incident. She had abnormally low peak expiratory flow readings, but had a clinical history of asthma. 6. No serious sequelae were encountered, but the incidence of burns in these patients was higher than would be expected from a review of the literature. However, very little data on the effects of tear gas in a riot situation has been published. There have been reports of high concentrations of CS gas causing reactive airways dysfunction but this was not seen in our group of patients.

A new double-strength (84 micrograms/spray) formulation of beclomethasone dipropionate (BDP-ds) as an aqueous suspension has been introduced to control symptoms of allergic rhinitis with once-daily intranasal dosing. This paper reviews the results of three clinical reports which show that BDP-ds given once a day is more effective than placebo and as effective as regular-strength beclomethasone dipropionate given twice daily in reducing the nasal symptoms of seasonal allergic rhinitis. Symptom improvement was seen within 2 days of treatment initiation and was maintained for the subsequent 4 weeks. BDP-ds was found to be as safe and well tolerated as placebo. Adverse effects, which were generally mild, included headache, nasal burning/irritation, epistaxis, coughing, and pharyngitis. BDP-ds is safe for children as young as 6 years of age, and its once-daily dosing schedule may improve patient compliance.

Sore throat is a common presenting complaint. Although patients often are concerned that they may have group A beta-hemolytic streptococcal (GABHS) pharyngitis, most sore throats are not caused by this infection. A number of illnesses and conditions present as sore throat. After life-threatening conditions are excluded, efforts to identify and treat patients with GABHS pharyngitis are appropriate. Efforts should include a directed history and physical examination, looking for exudative pharyngitis with fever, adenopathy and lack of cough or other respiratory symptoms. These findings predict a positive GABHS culture rate of 50 percent or more. The rapid Streptococcus test has a high positive predictive value, but it has a lower sensitivity rate. Treatment strategies for patients with sore throat are based on epidemiologic factors, signs and symptoms, and results of laboratory tests.

One hundred and twenty five children (median age 8.71 years) suffering from perennial allergic rhinitis were treated in a randomized, double-blind, parallel group study comparing azelastine nasal spray 0.14 mg/nostril twice daily (0.56 mg/day) and placebo nasal spray. Medication was given for a period of 6 weeks which followed a 2 week placebo washout period in all patients. Subjects were aged between 5 and 12 and were skin prick positive to either house dust mites and/or cat or dog dander. Concomitant anti allergic treatment was not permitted during the study. Severity of rhinitis symptoms was scored daily by the child or his/her parents on a diary card using a visual analogue scale (VAS) for each evaluated symptom: 0, absent-100, could not be worse. Mean weekly scores were calculated. Symptoms evaluated were: sneezing, nasal blockage, nasal itch and rhinorrhea. In addition, at each clinic visit the investigator evaluated symptoms using a verbal score of 0, no symptom-3, severe. Compared to the baseline, for each of the six study weeks, the reduction in the VAS scores for all four symptoms was statistically greater for the azelastine group compared to the placebo group. The investigator's assessment at clinic visits bore out these results. Both azelastine nasal spray and placebo were well tolerated, no serious adverse events were reported. During the treatment phase of the study a total of 36 adverse events were reported by 25 patients (azelastine 10, placebo 15). The most frequently occurring events were pharyngitis (azelastine 5, placebo 3), cough (azelastine 3, placebo 1) and bronchitis (azelastine 1, placebo 3). In conclusion, azelastine has been shown to be effective in the treatment of perennial rhinitis in children aged 5-12 years and to be superior to placebo in the relief of all symptoms assessed, namely sneezing, nasal blockage, nasal itch and rhinorrhea.
