Despite its frequent clinical use in analgesic agents, caffeine has not been accepted unequivocally as an analgesic adjuvant. To evaluate this activity of caffeine, we used new study methods in a randomized controlled trial on patients with acute sore throat due to tonsillopharyngitis. Patients were randomly assigned to receive a single dose of one of three treatments: 800 mg of aspirin with 64 mg of caffeine (n = 70), 800 mg of aspirin (n = 68), or placebo (n = 69). Under double-blind conditions, during a 2-hour evaluation period, patients used different rating scales to assess pain intensity, change in pain, relief, and two qualities of throat pain, how swollen the throat felt, and difficulty swallowing. Aspirin with caffeine and aspirin alone were significantly more effective than placebo for all efficacy measurements from 30 minutes through 2 hours and overall. The aspirin-caffeine combination also showed evidence of activity at 15 minutes on the relief scale. Aspirin with caffeine was more effective than aspirin alone after 30 minutes and over the entire study period. For patients with fever, both active treatments were equally effective antipyretic agents. We conclude, therefore, that 800 mg of aspirin, given alone or with 64 mg of caffeine, is an effective analgesic and antipyretic agent. Because the aspirin-caffeine combination is significantly more effective than aspirin alone as an analgesic, we also conclude that 64 mg of caffeine is an analgesic adjuvant.

GABHS is the most common bacterial cause of tonsillopharyngitis, but this organism also produces acute otitis media; pneumonia; skin and soft-tissue infections; cardiovascular, musculoskeletal, and lymphatic infections; bacteremia; and meningitis. Most children and adolescents who develop a sore throat do not have GABHS as the cause; their infection is viral in etiology. Other bacterial pathogens produce sore throat infrequently (e.g., Chlamydia pneumoniae and Mycoplasma pneumoniae), and when they do, other concomitant clinical illness is present. Classic streptococcal tonsillopharyngitis has an acute onset; produces concurrent headache, stomach ache, and dysphagia; and upon examination is characterized by intense tonsillopharyngeal erythema, yellow exudate, and tender/enlarged anterior cervical glands. Unfortunately only about 20% to 30% of patients present with classic disease. Physicians overdiagnose streptococcal tonsillopharyngitis by a wide margin, which almost always leads to unnecessary treatment with antibiotics. Accordingly, use of throat cultures and/or rapid GABHS detection tests in the office is strongly advocated. Their use has been shown to be cost-effective and to reduce antibiotic overprescribing substantially. Penicillin currently is recommended by the American Academy of Pediatrics and American Heart Association as first-line therapy for GABHS infections; erythromycin is recommended for those allergic to penicillin. Virtually all patients improve clinically with penicillin and other antibiotics. However, penicillin treatment failures do occur, especially in tonsillopharyngitis in which 5% to 35% of patients do not experience bacteriologic eradication. Penicillin treatment failures are more common among patients who have been treated recently with the drug. Cephalosporins or azithromycin are preferred following penicillin treatment failures in selected patients as first-line therapy, based on a history of penicillin failures or lack of compliance and for impetigo. GABHS remain exquisitely sensitive to penicillin in vitro. There are several explanations for penicillin treatment failures, but the possibility of copathogen co-colonization in vivo has received the most attention. Treatment duration with penicillin should be 10 days to optimize cure in GABHS infections. A 5-day regimen is possible and approved by the United States Food and Drug Administration for cefpodoxime (a cephalosporin) and azithromycin (a macrolide). Prevention of rheumatic fever is the primary objective for antibiotic therapy of GABHS infections, but a reduction in contagion and faster clinical improvement also can be achieved. Development of streptococcal toxic shock syndrome and necrotizing fasciitis ("flesh-eating bacteria") are rising concerns. The portal of entry for these invasive GABHS strains is far more often skin and soft tissue than the tonsillopharynx.

Fifty-one children aged 2-14 years with recurrent tonsillopharyngitis, presenting dysphagia, fever and lymphadenitis, with more than two similar episodes in the last three years and showing a beta-hemolytic group A streptococci in the pharyngeal smear, were studied. They underwent random treatment for ten days with phenoxymethylpenicillin (40-60 mg/kg/day) (n = 28) or amoxicillin-clavulanic acid (20-40 mg/kg/day) (n = 23) taken orally three times a day. Clinical and bacteriological tests were carried out at 10 days and 2, 6 and 12 months post-treatment. The clinical and bacteriological results showed the superiority of the amoxicillin-clavulanic acid treatment both in the short term (disappearance of symptoms) and in the long term (decrease in recurrence). These results support the idea that betalactamases produced by the pharyngeal flora play an important role in the failures of penicillin.

A cross-sectional study was conducted over a 1-year period (1 January-31 December 2000) during which cases suffering from uncomplicated tonsillopharyngitis were recruited from the private and public health services in Alexandria. The objective was to determine the prevalence of group A-beta haemolytic streptococci (GABHS) among children suffering from tonsillopharyngitis and to identify the clinical criteria predicting GABHS pharyngitis in children. A total of 578 children aged between 1 and 15 years with a mean of 6.3 +/- 3.7 years, presenting with sore throat were enrolled in the study. Demographic data and presenting signs and symptoms for each patient were recorded on a standardized form and a throat swab was taken using the filter paper technique. The overall prevalence of GABHS was 17 per cent and the highest isolation rate was reported in children aged 10-15 years. Non-GABHS comprised 11.9 per cent of the total isolates. The most prevalent of them were group C and G streptococci. The highest frequency of both GABHS and non-GABHS was in early spring. Significant predictors of GABHS pharyngitis were: age 10-15 years, the presence of dysphagia, vomiting, pharyngeal exudate, and scarlatiniform rash. Watery eyes and/or rhinitis had a protective value against the diagnosis of GABHS pharyngitis, while fever was considered to be a non-specific finding in cases with GABHS pharyngitis. Antibiotic sensitivity test showed higher sensitivity to both penicillin and erythromycin. Only 1 per cent of the GABHS isolates showed resistance to cephadroxil. We concluded that a syndrome of signs and symptoms could be used as a clinical predictor for the diagnosis of GABHS pharyngitis.
