[Primary malignant lymphoma of the mandible. A study of 3 cases and a review of the literature].

Three cases of non-Hodgkin malignant lymphoma (LMNH in text) of the mandible are described, and findings compared with those reported in the literature. The mean age of patients was 46 years, without any significant male preponderance (sex ratio: 1.19), the preferential localization being the horizontal branch. Detection of the lesion was, by decreasing order of frequency, based on: mandibular tumefaction, pain, local neurologic disorders and dental mobility. Diagnosis was confirmed by histology of a deep biopsy specimen, facilitated by immunohistochemical techniques: the most frequently encountered histologic type was the diffuse large cell type (group G of the international clinical classification). Diagnosis was difficult because of the similarity of the presentation with other dental diseases and the difficulty of histologic interpretation. The principal differential diagnoses are osteomyelitis, sarcoma and carcinoma, the first one raising the risk of a long delay in diagnosis, the others of unnecessary mutilating surgery. The lesion was localized in more than half the cases, without accompanying enlarged cervical glands or metastatic visceral invasion. Treatment was by radiotherapy, usually in association with multiple chemotherapy because of the high incidence of intermediate or elevated histologic malignancy. Global prognosis was good (5 year total clinical remission rate of more than 60%), the poorest prognostic factor being metastatic spread.

[Mucoviscidosis and allergic bronchopulmonary aspergillosis].

Allergic bronchopulmonary aspergillosis (ABPA) is a severe disease inducing bronchopulmonary anatomic lesions which complicate those already present in patients with cystic fibrosis. The frequency of this association is estimated between 0.6 and 10% according to American studies. Diagnosis of ABPA is difficult, as findings such as sibilant rales, pulmonary infiltrates, bronchiectasies, anti-aspergillus precipitins may be present as single features in patients with cystic fibrosis. Thus it is important to ascertain the diagnosis as oral corticosteroid treatment is the only one able to prevent evolution towards bronchiectasies and pulmonary fibrosis.

[Accelerated desensitization with Dermatophagoides pteronyssinus in severe asthmatic children. Evaluation after one year of immunotherapy].

An homogeneous group of 17 children with severe chronic asthma were given a rush immunotherapy with standardized Dermatophagoides pteronyssinus extracts. Maintenance dose was injected monthly for one year. Symptom and medication scores as well as functional (lung function tests, specific nasal challenges), immunologic and allergic parameters (skin tests, total serum IgE, specific IgE and IgG4) were recorded before and at the end of the study. Rush immunotherapy was well tolerated in spite of some moderate systemic adverse reactions. Symptom and medication scores improved in 10 children. Nasal and skin sensitivity decreased in respectively 3 and 7 children. However there was no correlation between the improvement of quality of life and laboratory results. This study shows that specific immunotherapy is possible in children with severe asthma. Its efficacy should be assessed by symptom and medication scores.

[Lingual necrosis after radiotherapy. Radiation arteritis?].

Describing a case of tongue necrosis five years after Radiotherapy for a T3N0M0 carcinoma of the tonsil, the authors discuss the principal causes of these necrosis and insist on the potentialisation of the effects of radiotherapy on latent arterial disease.

[A case of botulism in a 11-month-old infant].

We report a case of botulism in a 11 month-old infant. Hypotonia complicated by progressive bulbar paralysis revealed the disease. Botulism B toxin was present in serum on the 8th day of the disease. On the occasion of this case report the clinical, diagnostic, epidemiological and pathophysiologic aspects of infant botulism are reviewed. The relationship between sudden infant death and botulism is discussed.

[Eosinophilic lung in children].

Pulmonary eosinophilia is an anatomo-clinical entity in which pulmonary parenchymatous infiltrates are associated with tissue hypereosinophilia. Blood eosinophilia which is very frequent but not absolutely constant makes the diagnosis likely. Four case reports illustrating pathophysiological mechanisms show its reality in pediatrics as well as its etiological diversity: parasitosis (filariasis), allergic bronchopulmonary aspergillosis complicating cystic fibrosis, vasculitis (Churg-Strauss syndrome) and chronic pulmonary eosinophilia, the last diagnosis being a diagnosis of exclusion. Pulmonary eosinophilia is rare in children and might not be recognized by pediatricians. Diagnosis might be urgent, in the case of dyspnea, hypoxia and/or threatening respiratory signs. The severity of some pulmonary eosinophilias emphasizes the toxicity of the eosinophil granulocyte content. Especially, the major basic protein is capable of destroying the pulmonary epithelium and of facilitating human basophil degranulation. The effect of corticosteroid therapy, spectacular in chronic pulmonary eosinophilia, may be related to their inhibitory effect on eosinophils and by stabilizing cellular membranes.

165 renal carcinomas: accuracy of imaging for diagnosis and spread--cost efficiency.

Based on a study of 165 cases of renal carcinoma, we compare the relative diagnosis efficiency of different methods: intravenous urography (IVU), ultrasound (U.S.), arteriography and computed tomography (C.T.). Our evidence enables us to assert the excellent diagnostic accuracy of ultrasound and the superiority of computed tomography for good staging of renal carcinoma. The cost efficient methods for the evaluation of this tumour are intravenous urography (to show and localize the renal mass), ultrasound (to assert the echogenic structure) and computed tomography (to establish the diagnosis of carcinoma and judge its spread).
