Computed tomography evaluation of temporomandibular joint alterations in patients with class II division 1 subdivision malocclusions: condyle-fossa relationship.

Thirty persons with Class II Division 1 subdivision malocclusions, ranging in age from 12 years 8 months to 42 years, underwent computed tomography of the temporomandibular joints. The images obtained from sagittal slices were used to assess the depth of the mandibular fossa, the angulation of the posterior wall of the articular tubercle, the condyle-fossa relationship, and the concentric position of the condyles associated with this malocclusion. Paired Student t tests were applied, and Pearson product moment correlations (r) were determined after measurements on both Class I and Class II sides were obtained. No statistically significant asymmetries were found in the depth of the mandibular fossa, the angulation of the posterior wall of the articular tubercle, or the condyle-fossa relationship. However, a statistically significant (P <.05) anterior positioning of the condyles was observed.     

Neurologic outcome after heart transplantation in Chagas' disease

Objective - To evaluate the neurologic morbidity after orthotopic heart transplantation (OHT), we examined consecutive Chagas' (Ch) and non-Chagas' (NCh) patients, before and after surgery. Material and methods - We undertook neurological and neuropsychological evaluations in Ch and NCh patients with end-stage cardiac failure, from September 1993 to September 1995. Results - Of 10 Ch patients (mean age=33.6 years; 7 male; mean follow-up=10.8 months) and 13 NCh patients (mean age=50.9 years; 12 male; mean follow-up=15 months) 3 died (rejection and sepsis) without neurologic symptoms. Neurologic complications occurred in 4 Ch and 5 NCh patients. Two Ch patients had skin and myocardial Chagas' reactivation successfully treated, without CNS involvement. NPS performance and return to work rates were similar in both groups. Conclusions - Although Ch patients are potentially at a higher risk of Trypanosoma cruzi reactivation, in addition to all known neurologic complications of OHT, early neurologic complications detected in this sample were similar in Ch and NCh patients and could not be specifically related to Chagas' disease.     

中国西部城市和农村开展面粉营养素强化的可行性分析

目的通过对甘肃农产区居民的饮食习惯、营养知识和态度的调查,从需方的角度对开展面粉营养素强化的可行性进行探讨。方法采用定性和定量调查相结合的方法,对4个地区的城市和农村的男性和女性分别进行现状和原因的调查分析。结果被调查地区多数城市(92.7%)和农村(60.7%)家庭日常饮食以面食为主,94.7%的城市家庭购买面粉,而在农村地区,多数家庭自己种植或购买小麦。城市居民较农村对营养和维生素有更多的了解和关注。农村男性对面粉营养素强化持怀疑态度,女性更加关注孩子的营养,认为目前的饮食单一,孩子可能营养不足。结论与农村地区相比,城市地区的社会经济条件和知识基础较利于开展面粉强化工作。     

Three cases of infection withFusarium species in neutropenic patients

Three cases are reported of disseminated infection due toFusarium species in severely neutropenic patients. The clinical findings in all patients included fever, painful disseminated nodular skin lesions and severe myalgia. The outcome was fatal despite early administration of amphotericin B. The portal of entry of the organism was probably the nasal sinus in two cases.     

Clinical aspects of tumour involvement of the pulmonary vessels.

The involvement of the pulmonary vessels by tumour emboli may lead to a clinical picture defined as 'subacute cor pulmonale'. Information about this syndrome has been limited to case reports and a few series. A study of 214 autopsied cancer patients was undertaken to investigate the clinical signs and symptoms of tumour involvement of the pulmonary vessels (TIPV). The lungs were removed as a block and 15 sections (3 from each lobe) were analyzed. Clinical data about right ventricular failure, dyspnoea, cough, pleuritic chest pain, cyanosis, engorgement of jugular veins, peripheral oedema, haemoptysis and haemoptoic sputum were obtained from the medical records of each patient. Tumour emboli were detected in 89 cases, and no respiratory symptoms were recorded in 39. The presence of dyspnoea and cyanosis were highly significant in the group with TIVP, and right ventricular failure and peripheral oedema showed slight significant differences between the patients with and without TIPV. The classical picture of subacute cor pulmonale was observed in 13 patients and TIPV was considered to be the main cause of death in 29 cases. Our results indicate that although the development of subacute cor pulmonale was rare in patients with cancer, TIPV may be suspected when the patient presents respiratory distress and should be included in the differential diagnosis of dyspnoea in cancer patients.     

Treatment of traumatized primary teeth: a conservative approach

This retrospective study examined some different types of treatment to primary teeth. The aim of this study was to assess the treatment of traumatized primary teeth and the importance of a long-term follow up. Brazilian children in the age group of 1-4 years from a baby clinic took part in the study. Three hundred and fifteen patients suffered some type of traumatic injury, a total of 338 affected teeth. Data were registered in specific records and submitted to statistic analysis. The most prevalent type of treatment was monitor only (85%) followed by tooth extraction and endodontic procedure. Invasive treatments were performed in case of severe traumas, usually 6 months after the injury. We verified that a careful follow up might be the preferential choice to the treatment of traumatic primary teeth even in some severe cases.
