[Clinical study on amoxicillin in otorhinolaryngological field (author's transl)].

Clinical effect of amoxicillin was evaluated in 29 cases of the acute infections of ear, nose and throat: 8 cases of acute purulent otitis media, one case of acute otitis externa, one case of furuncle of the ear, 2 cases of acute sinusitis, 12 cases of acute lacunar tonsillitis, 2 cases of pharyngolaryngitis, one case of acute cervical lymphadenitis, one case of phlegmon of the face and one case of acute gingivitis. The following results were obtained from the clinical and laboratory studies. 1) The therapeutic results were excellent in 18 cases, good in 5 cases, fair in 3 cases and poor in 3 cases. The effect was observed in 79.3% of the patients treated. 2) The causative bacteria were: 3 strains of beta-Streptococcus hemolyticus, 4 strains of Hemophilus, 4 strains of Staphylococcus aureus, one strain of Diplococcus pneumoniae, one strain of Gram-positive Diplococcus and Gram-negative Bacillus. Clinically good results were obtained in patients infected with beta-Streptococcus hemolyticus, Hemophilus and Diplococcus pneumoniae. 3) No side effect was observed with amoxicillin, except slight diarrhea in one case. This side effect disappeared by cessation of the administration. 4) No unfavourable influence was noticed on peripheral blood, liver function nor renal function by administration of amoxicillin. 5) From the results of this series, amoxicillin seems to be useful in the treatment of acute infections of the ear, nose and throat.
