          Abstract

          La amigdalectomía es la intervención quirúrgica más frecuente en otorrinolaringología y sus indicaciones son ampliamente conocidas en la especialidad. El avance en el conocimiento de sus funciones inmunológicas ha determinado su uso en el tratamiento de otras enfermedades tales como la nefropatía por IgA, síndromes neuropsiquiátricos, el síndrome de fiebre recurrente, algunas entidades dermatológicas, entre otras. Pretendemos así, revisar la literatura para evaluar la evidencia disponible que sustente lo que denominamos indicaciones no tradicionales. Al parecer, la evidencia a favor del uso de amigdalectomía en el tratamiento de algunas de estas enfermedades es sólido, mientras que para otras aún no supera la suposición teórica, pues sólo se cuenta con casos aislados. Consideramos necesario estudios más extensos, con mayor calidad metodológica para definir mejor la indicación de amigdalectomía. Esto, más la evaluación multidisciplinaria de cada caso nos debiera conducirá la mejor decisión.

          Tonsillectomy is the most common surgical procedure in otorhinolaryngology and their indications are well known in the field. The advance in knowledge of their immune function has determined its use in the treatment of other diseases such as IgA nephropathy neuropsychiatric syndromes, periodic fever syndrome, some dermatologic entities, and others. We review the literature to evaluate the available evidence that supports what we cali nontraditional indications. Apparently the evidence for the use of tonsillectomy in the treatment of some diseases is solid, while others still not overcome the theoretical assumption, since there are only isolated cases. Larger studies are needed to consider, with higher methodological quality, to better define the indication for tonsillectomy. This and the multidisciplinary assessment of each case should lead us to the best decision.

          Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections: clinical description of the first 50 cases.

          The purpose of this study was to describe the clinical characteristics of a novel group of patients with obsessive-compulsive disorder (OCD) and tic disorders, designated as pediatric autoimmune neuropsychiatric disorders associated with streptococcal (group A beta-hemolytic streptococcal [GABHS]) infections (PANDAS). The authors conducted a systematic clinical evaluation of 50 children who met all of the following five working diagnostic criteria: presence of OCD and/or a tic disorder, prepubertal symptom onset, episodic course of symptom severity, association with GABHS infections, and association with neurological abnormalities. The children's symptom onset was acute and dramatic, typically triggered by GABHS infections at a very early age (mean = 6.3 years, SD = 2.7, for tics; mean = 7.4 years, SD = 2.7, for OCD). The PANDAS clinical course was characterized by a relapsing-remitting symptom pattern with significant psychiatric comorbidity accompanying the exacerbations; emotional lability, separation anxiety, nighttime fears and bedtime rituals, cognitive deficits, oppositional behaviors, and motoric hyperactivity were particularly common. Symptom onset was triggered by GABHS infection for 22 (44%) of the children and by pharyngitis (no throat culture obtained) for 14 others (28%). Among the 50 children; there were 144 separate episodes of symptom exacerbation; 45 (31%) were associated with documented GABHS infection, 60 (42%) with symptoms of pharyngitis or upper respiratory infection (no throat culture obtained), and six (4%) with GABHS exposure. The working diagnostic criteria appear to accurately characterize a homogeneous patient group in which symptom exacerbations are triggered by GABHS infections. The identification of such a subgroup will allow for testing of models of pathogenesis, as well as the development of novel treatment and prevention strategies.

            Periodic fever syndrome in children.

            To describe the presentation, clinical course, therapeutic response, and long-term follow-up of patients with a syndrome of periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA). Patients with PFAPA (n = 94) referred over a 10-year period completed a registry form and provided medical records. Follow-up telephone calls were made in late 1997 to determine the persistence of episodes and sequelae. PFAPA episodes lasted 4.8 days (95% confidence interval 4.5 to 5.1) and recurred every 28 days (confidence interval 26 to 30), with a maximal temperature of 40.5 degrees C (confidence interval 40. 4 degrees to 40.6 degrees ). Of the 83 children available for follow-up, 34 no longer had episodes. In the remainder the episodes did not differ in character but recurred less frequently over time. The affected children had no long-term sequelae. Glucocorticoids were highly effective in controlling symptoms. Tonsillectomy and cimetidine treatment were associated with remission in a small number of patients. PFAPA is a not uncommon cause of periodic fever in children. In some children the syndrome resolves, whereas symptoms in others persist. Long-term sequelae do not develop. The syndrome is easily diagnosed when regularly recurring episodes of fever are associated with aphthous stomatitis, pharyngitis, or cervical adenitis.

              Efficacy of tonsillectomy for recurrent throat infection in severely affected children. Results of parallel randomized and nonrandomized clinical trials.

              We studied the efficacy of tonsillectomy, or tonsillectomy with adenoidectomy, in 187 children severely affected with recurrent throat infection. Ninety-one of the children were assigned randomly to either surgical or nonsurgical treatment groups, and 96 were assigned according to parental preference. In both the randomized and nonrandomized trials, the effects of tonsillectomy and of tonsillectomy with adenoidectomy were similar. By various measures, the incidence of throat infection during the first two years of follow-up was significantly lower (P less than or equal to 0.05) in the surgical groups than in the corresponding nonsurgical groups. Third-year differences, although in most cases not significant, also consistently favored the surgical groups. On the other hand, in each follow-up year many subjects in the nonsurgical groups had fewer than three episodes of infection, and most episodes among subjects in the nonsurgical groups were mild. Of the 95 subjects treated with surgery, 13 (14 per cent) had surgery-related complications, all of which were readily managed or self-limited. These results warrant the election of tonsillectomy for children meeting the trials' stringent eligibility criteria, but also provide support for nonsurgical management. Treatment for such children must therefore be individualized.
