The role of condylectomy in the treatment of mandibular laterognathism in children

In 7 cases of mandibular laterognathia caused by condylar hypertrophy, the authors specify the clinical and teleradiological features in adolescents. They emphasize the inadequacy of lateral teleradiography and of its measurements, and the need for three-dimensional investigation. In adolescents, secondary deformations, either spontaneous or therapeutic, are rare, and the treatment preferred is condylectomy based on the study of casts. The immediate results of this techniques are satisfactory. The long-term consequences on growth and temporomandibular pathology have been studied.     

Resolution of otitis media with effusion with the use of a stepped treatment regimen of trimethoprim-sulfamethoxazole and prednisone

This double blind, placebo-controlled trial was designed to determine whether intervention with a stepped regimen of trimethoprim-sulfamethoxazole (TMP-SMX) and prednisone would prevent high risk children from developing chronic otitis media with effusion (OME) and recurrent acute otitis media. Forty-two children were enrolled, assigned to treatment with active drug or placebo and then examined at 2-week intervals. They received TMP-SMX (or placebo) during the first 2 weeks, TMP-SMX and prednisone (or placebo) during Weeks 3 and 4 for persistent OME and TMP-SMX (or placebo) for Weeks 5 and 6 if OME was still unresolved. After treatment 48% of active drug and 14% of placebo subjects resolved OME bilaterally (P less than 0.05). Active drug subjects also had fewer acute otitis media episodes than placebo subjects while receiving study treatment (P less than 0.01). Although this treatment regimen produced short term OME resolution, long term benefits were not demonstrated.

Comparison of the treadmill exercise score and single-photon emission computed tomographic thallium imaging in risk assessment

Background  

This study compared the prognostic value of exercise single-photon emission computed tomographic (SPECT) thallium imaging with that of treadmill exercise score in medically treated patients with coronary artery disease (CAD)     

Non-Hodgkin's lymphoma: a differential diagnosis of otogenic facial paralysis

Of all the neoplastic conditions of the lymphatic system, Non-Hodgkin's lymphoma (NHL) represents a heterogenous group. As well as lymph nodes NHL can involve extranodal sites, including regions in head and neck. The mouth and oropharynx are typical extranodal sites, and the ENT surgeon should be aware of this possibility of the swift diagnosis of NHL is to be made. We report two patients with rare invasion of the middle ear, facial nerve paresis, and asymptomatic cerebral involvement by Non-Hodgkin's lymphoma.     

Hydronephrosis after aortofemoral bypass graft. A prospective study

This prospective study was designed to determine the frequency and natural history of hydroureteronephrosis (HUN) after placement of an aortobifemoral vascular graft. A total of 30 patients were evaluated by the study protocol, which included: pre and postoperative biological kidney function tests, preoperative and early postoperative (14th day) intravenous pyelograms and a late (mean 18th month) urologic examination by renal ultrasonic tomography. Four asymptomatic, early cases of HUN were observed in the 57 ureters examined (7%); all four complications regressed in less than 30 days. No cases of symptomatic early or late HUN were observed in this series. Asymptomatic early HUN was a frequent complication in our series (7%) but its benign course does not justify systematic screening. These asymptomatic complications contrast with the symptomatic cases of early or late HUN reported in the literature which necessitated urologic and vascular investigations.
