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.

Efficacy of short‐term oral cobalamin therapy for the treatment of cobalamin deficiencies related to food‐cobalamin malabsorption: A study of 30 patients

Background: It has been suggested that oral cobalamin (vitamin B₁₂) therapy may be an effective therapy for treating cobalamin deficiencies related to food‐cobalamin malabsorption. However, the duration of this treatment was not determined. Patients and method: In an open‐label, nonplacebo study, we studied 30 patients with established cobalamin deficiency related to food‐cobalamin malabsorption, who received between 250 and 1000 μg of oral crystalline cyanocobalamin per day for at least 1 month. Endpoints: Blood counts, serum cobalamin and homocysteine levels were determined at baseline and during the first month of treatment. Results: During the first month of treatment, 87% of the patients normalized their serum cobalamin levels; 100% increased their serum cobalamin levels (mean increase, +167 pg/dl; P < 0.001 compared with baseline); 100% had evidence of medullary regeneration; 100% corrected their initial macrocytosis; and 54% corrected their anemia. All patients had increased hemoglobin levels (mean increase, +0.6 g/dl) and reticulocyte counts (mean increase, +35 × 10⁶/l) and decreased erythrocyte cell volume (mean decrease, 3 fl; all P < 0.05). Conclusion: Our findings suggest that crystalline cyanocobalamin, 250–1000 μg /day, given orally for 1 month, may be an effective treatment for cobalamin deficiencies not related to pernicious anemia.     

Locoregional chemotherapy in the treatment of liver metastasis of breast carcinoma]

Locoregional chemotherapy enables specific treatment of organ metastases by using a dosage of medication that is maximally effective but only has minimal side effects on other organs. Since 1983, we have applied this procedure in patients whose liver represented the only target-organ of metastases. Between 1983 and 1990, locoregional chemotherapy was performed in 59 women suffering from liver metastases of breast cancer. The average age of our patients was 52 years. 4 patients were treated for solitary metastases that could not be resected, in 5 patients the infiltration of hepatic parenchyma with metastases accounted to 25%, in 32 patients hepatic infiltration ranged between 25% and 75% and in 18 patients it surpassed 75%. In 39% of our patients, a partial remission occurred. The mean period of survival after beginning of treatment was 149 days, whereas the longest survival time lasted 1009 days. We conclude that the locoregional chemotherapy, destined for treatment of liver-metastases of breast cancer, with a mean survival time of only five months could insufficiently satisfy our expectations. Therefore, a decision to administer such palliative therapy should be made on an individual basis. In our opinion, one indication represents solitary metastases that are not resectable, a further indication is pain due to expansion of the liver capsule because of diffuse metastases.     

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.
