The incidence of acute otitis media and its response to treatment only with nose drops and analgesics (but without antibiotics or myringotomy) were assessed over three months by 45 doctors in and around Tilburg. In addition, over 17 months 60 general practitioners assessed the effects of this limited treatment in children aged 2 to 12 years and referred all those in whom the condition took an unsatisfactory course (either a severe course--illness continuing beyond three to four days with high temperature or pain, or both--or persistent discharge after 14 days) to an ear, nose, and throat specialist. Those referred because of appreciable illness continuing beyond three or four days were entered into a further study, comparing the effects of myringotomy alone, antibiotics alone, and myringotomy and antibiotics combined. Bacteriology was assessed in all children in whom the course of the condition was unsatisfactory. More than 90% of an estimated 4860 children seen over 17 months (estimation based on incidence of severe course in the three month study) recovered within a few days. The course of the condition was severe in only 126 (2.7%) patients; haemolytic streptococci group A were identified in 30 of these 126 patients but Haemophilus influenzae in only one. One hundred of these patients with a severe course entered the trial of treatment, which showed antimicrobial treatment either alone or in combination to be more effective than myringotomy alone. Whether combined treatment was more effective than antibiotics alone remained unconfirmed. Acute otitis media in children can be treated with nose drops and analgesics alone for the first three to four days. Patients in whom this regimen is not accompanied by satisfactory recovery can be recognised within a short time and treated by the general practitioner.

Cefazolin sodium was tested in vitro against 308 isolates of Enterobacteriaceae, Pseudomonas aeruginosa, Neisseria meningitidis, Haemophilus influenzae, Staphylococcus aureus, and enterococcus. Broth and agar dilution and disk diffusion techniques were used with at least two sizes of inocula of organisms. Cefazolin was also studied in the treatment of 85 hospitalized patients with a variety of serious infections. In concentations of 5 mug or less/ml, cefazolin inhibited and killed more than 90% of isolates of Enterobacteriaceae with the exception of indole-positive Proteus and Enterobacter species. No isolate of P. aeruginosa and only a few of Enterobacter and enterococci were killed by 25 mug of cefazolin/ml, a concentration readily attainable in serum with a 500-mg dose given intramuscularly. Penicillin-susceptible as well as penicillin-resistant isolates of S. aureus were killed by 1 mug or less of cefazolin per ml; however, 25 mug/ml was required to kill 100% of the strains when the inoculum size was increased 100-fold. Cefazolin treatment appeared effective in 82 of 85 patients, including four with endocarditis. Pain was minimal after intramuscular injection, and thrombophlebitis was not observed in those treated intravenously. No patient developed a positive Coombs test, and no evidence of renal toxicity was apparent in clinical studies.

Therapy with moxalactam was evaluated in 71 patients with bacterial pneumonia. Ninety-two percent of patients with pneumonia due to gram-positive cocci, anaerobes, or Haemophilus influenzae were cured. One patient developed probable pneumococcal meningitis during treatment of sputum culture-positive pneumococcal pneumonia. Six of 10 patients with pneumonia due to Pseudomonas aeruginosa or Enterobacteriaceae were cured also. However, two of these patients became colonized with moxalactam-resistant organisms, which were of the same species as the organism that caused the original infection. Two of the four patients in whom treatment failed were infected with P. aeruginosa and then developed superinfection with moxalactam-resistant Pseudomonas. Phlebitis and pain on intramuscular injection were the most common adverse effects observed. The results of this study, demonstrate that moxalactam may constitute effective therapy for bacterial pneumonia, but the development of resistance during therapy may limit its usefulness against Pseudomonas infections.

Fifty-seven children, ages 1 month to 17 years, were treated with parenteral ceforanide. Most patients received 20 mg/kg of the drug intramuscularly every 12 hours. The mean duration of ceforanide therapy was 6.3 days (range, 3 to 14 days). Because ceforanide has a relatively long half-life of 1.94 +/- 0.43 hours (range, 1.1 to 3.3 hours), suprainhibitory plasma concentrations against most pathogens recovered from the study patients were maintained for 8 to 12 hours after a dose. Ceforanide diffused well into abscess cavities and joint fluid. Initial clinical response was satisfactory in all patients; however, one patient with Haemophilus influenzae type b bacteremia had relapse of bacteremia one week after ceforanide therapy. Ceforanide was well-tolerated with minimal pain at the site of intramuscular injections. Other side effects were minor and transient.

Acute epiglottitis is rare in adolescents. Respiratory compromise may not occur early. Physicians should consider this diagnosis in their adolescent patients who complain of pain and dysphagia, with or without visible pharyngitis. Airway maintenance is paramount. The antibiotic used should include coverage for Hemophilus influenzae, type B. The case presented here illustrates these points.

The effect of peroral penicillin V (55 mg/kg/day) on acute otitis media was investigated in 149 children between the ages of one and ten years in a double-blind, placebo-controlled investigation. The parameters of the disease employed were symptom scores for earache, the use of analgetics, otoscopy, as well as tympanometry. The children were followed up for three months. Penicillin had a significant effect on pain on the second day of treatment. The acute course of the disease was satisfactory in 69% of the children in the placebo group and in 86% in the penicillin group. In patients with pneumococci or hemolytic streptococci in the rhinopharynx, the pain already disappeared after one to two doses of penicillin, whereas the treatment had no effect on the patients with Haemophilus influenzae. There was no difference between the penicillin and placebo groups with regard to the results of otoscopy and tympanometry after one week, one month and three months. No serious complications were observed. It is concluded that an attitude of "masterful inactivity" with regard to the treatment of acute otitis media is justifiable, and in the majority of cases advisable, provided sufficient analgesic treatment is given and also that the patient can be closely followed. As there are still many unanswered questions more controlled investigations are warranted.

The effect of peroral penicillin-V (55 mg/kg/day in 7 days) on acute otitis media was studied in 149 children between the ages of 1 and 10 years in a double-blind, placebo-controlled investigation. The parameters of the disease employed were symptom scores for earache, fever and common cold, the use of analgetics, otoscopy, as well as tympanometry. The children were followed-up for 3 months. Penicillin had no effect on fever and common cold, but earache was significantly reduced on the 2nd day of treatment. The acute course of the disease was satisfactory in 69% of the children in the placebo group and in 86% in the penicillin group. In patients with pneumococci or haemolytic streptococci in the nasopharynx, the pain disappeared after 1-2 doses of penicillin, whereas the treatment had no effect in children with Haemophilus influenzae. There was no difference between the penicillin and the placebo groups with regard to the results of otoscopy and tympanometry after 1 week, 1 month and 3 months. No serious complications were observed. It is concluded that an attitude of "masterly inactivity" with regard to the treatment of acute otitis media is justifiable, provided sufficient analgesic treatment is given and also that the patient can be closely followed. As there are still many unanswered questions more controlled investigations are warranted.

In a series of 175 children with suspected sinusitis the symptoms and clinical signs were compared with the radiologic and bacteriologic findings. URI, purulent nasal secretion and pain were the main symptoms predicting radiologic changes. In 75% of the patients the presence of two or three of these symptoms was co-existent with major radiological changes. As assessed by nasopharyngeal culture Haemophilus influenzae seemed to be the major pathogen.

Thirty children with clinical evidence of otitis media underwent tympanocentesis. Streptococcus pneumoniae was the predominant organism recovered (63%). Three cases of Hemophilus influenzae, alone or in combination with S pneumoniae, were identified. Other organisms found were Staphylococcus albus, Neiserria species. Group A B-hemolytic Streptococcus, and anaerobes. In four patients (13%) no organism was recovered. All isolates were ampicillin susceptible. No relationship was found between WBC, temperature, or age and the organism recovered. Tympanocentesis did not provide any information resulting in an alteration of therapy. Tympanocentesis may be indicated for relief of pain or for periodic surveillance of organism sensitivities, but is not justified in the emergency department for uncomplicated acute otitis media.

To better understand the significance of viral upper respiratory tract infections in the pathogenesis of acute otitis media (OM), 27 adults underwent intranasal inoculation with influenza A virus. Monitoring consisted of antibody titer determination, tympanometry, and otoscopy. Microbiologic analysis consisted of cultures and polymerase chain reaction (PCR)-based detection for influenza A virus, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. All subjects became infected with the challenge virus. By day 4, 16 (59%) developed middle ear pressures of -100 mm H2O or below and 4 (25%) of them developed OM. One subject (4%) developed purulent OM requiring myringotomy for pain relief. Middle ear effusion cultures were negative. PCR analysis of that subject's middle ear effusion and nasal washes were positive for influenza A virus and S. pneumoniae. These findings support a causal role for viral upper respiratory tract infections in the pathogenesis of OM, possibly mediated by middle ear underpressures and viral and bacterial middle ear infection.
