title: [The treatment of acute recurrent pharyngotonsillitis].
abstract: OBJECTIVE
  In paediatric patients, recurrent febrile pharyngo-tonsillitis is usually due to chronic inflammation of the tonsils and/or adenoids: these episodes are often associated with other clinical manifestations (respiratory obstruction of naso-pharyngeal origin; auricular inflammation, especially effusive otitis media and acute otitis media; streptococcal beta-haemolytic Group A (SBEGA) infection, causing a distant disorder of varying severity and which may, therefore, give rise to serious pathological conditions). A retrospective multicentric investigation has, therefore, been carried out in order not only to further elaborate findings emerging from earlier studies, performed in other countries, in which random methods were used, but also to focus on: 1. the possible association of these clinical manifestations with recurrent febrile pharyngo-tonsillar inflammation in relation to frequency of the condition; 2. results obtained with adenoidectomy or with adeno-tonsillectomy, referring to the overall clinical outcome of the pathological condition, bearing in mind data emerging from the control groups, submitted to strict follow-up, associated with any medical treatment deemed necessary.
  
  
  METHODS
  The study population comprised 692 patients (394 male, 298 female), age range 2-11 years and with a minimum follow-up of 2 years. Considering the clinical manifestations emerging from the case history, the following two investigations were carried out: 1. the first, on 501 patients, all previously submitted to adeno-tonsillectomy in whom the recurrent febrile pharyngo-tonsillar inflammation had occurred, respectively > 4 or < or = 4 episodes during the last 12 months; 2. the second, on 455 patients in whom recurrent febrile pharyngo-tonsillar inflammation, in the 12 months prior to the beginning of the study, had been < or = 4 episodes: in 264 cases, adeno-tonsillectomy was carried out; in 144, adenoidectomy; 47 children were studied as controls and, therefore, submitted to watchful waiting. The results obtained were statistically analysed by chi2 and Fisher test: a "p" value of < 0.05 was considered statistically significant.
  
  
  RESULTS
  The first investigation showed that all symptomatological manifestations considered were resolved following adeno-tonsillectomy, in a significantly high percentage of cases (recurrent febrile pharyngo-tonsillar in flammation: 91.8%; naso-pharyngeal respiratory obstruction: 92.2%; pathological ASO titre: 69.8%; distant disorders probably due to SBEGA: 76%; effusive otitis media: 76%; acute recurrent otitis media: 87.5%). The most interesting clinical findings obtained can be summarized as follows: naso-pharyngeal respiratory obstruction is a frequent finding; the incidence is statistically higher in cases in which recurrent febrile pharyngo-tonsillar inflammation is less frequent (p < 0.05): in these patients, this is an important pathological manifestation indicating the need for surgery; the higher incidence is associated with at significant finding of pathological auricular processes; the percentages of recovery for naso-pharyngeal respiratory obstruction are statistically greater in the group of patients in whom the recurrent febrile pharyngo-tonsillar inflammation is more frequent: an identical result is found in patients with the effusive form of otitis media and in those with recurrent acute otitis media; a pathological ASO titre is more frequently found, the difference being statistically significant (p < 0.05), in the group of patients with more frequent recurrent febrile pharyngo-tonsillar inflammation, albeit this factor does not affect the percentage of recovery; also the favourable evolution and recovery of clinical distant manifestations, related to streptococcal beta-haemolytic Group A infection, are correlated with the return to normal of the ASO titre. The second investigation demonstrated the efficacy of surgical treatment, adeno-tonsillectomy and adenoidectomy, in all the clinical manifestations studied, the possibility of achieving resolution of recurrent febrile pharyngo-tonsillar inflammation even in the control subjects submitted to medical treatment, but also the lack of success, in the latter, as far as concerns naso-pharygeal respiratory obstruction, the pathological ASO titre and the inflammatory auricular processes.
  
  
  CONCLUSIONS
  The present investigations confirm previous observations emerging from randomized clinical studies, regarding the possibility to achieve valid prevention of recurrent febrile pharyngo-tonsillar inflammation, also in a large percentage of control patients submitted to watchful waiting; these investigations, however, also demonstrated that, in the control group, the percentage of subjects in whom recovery of other symptoms was achieved was very low compared to that in the groups submitted to surgery. In other words, clearly emerges as far as concerns the overall symptomatological picture of the patients, the efficacy of the surgical treatment, but also the lack of success of the medical treatments in all clinical manifestations associated with recurrent febrile inflammations. Therefore, it is necessary to select and advise the most suitable treatment strategy, not in relation to the Guidelines elaborated on the basis of results emerging from statistical research, that, due to the intrinsic methodology limits cannot be applied to all cases in an acritical fashion, but in relationship to the specific clinical picture of each individual patient.
