Validation of a questionnaire for clinical seizure diagnosis.

A detailed questionnaire has been devised for diagnosis of seizure type. It is suitable for administration by trained interviewers, either directly or by telephone. A comparison of physician-based and questionnaire-based diagnoses showed almost perfect agreement in classification of patients into those with seizures of either generalized or focal origin. Substantial to almost-perfect agreement was reached in diagnosis of patients with most individual seizure types. Disagreement in differentiation between simple and complex partial seizures (CPS) probably reflects the limitations of the clinical method rather than of the questionnaire itself. The questionnaire should be of value in large-scaled clinical and epidemiologic studies.

The psychological impact of implant-retained mandibular prostheses: a cross-sectional study.

Investigation of the psychological impact of implant-retained overdentures has demonstrated some positive benefits over traditional prosthetic treatment (ie, conventional complete dentures). The aim of the present study was to determine whether treatment response could be understood by controlling the degree of alveolar ridge resorption present. In a cross-sectional single-wave study by means of a questionnaire, patients who had received implant-retained mandibular dentures were compared with patients who had conventional mandibular dentures. For purposes of comparison, all patients in both groups wore conventional maxillary dentures. From the 87 patients who were invited to complete a postal questionnaire, 76 replies were received (85% response rate). The implant (n = 41) and denture (n = 35) patients were assessed on self-rated symptoms, denture satisfaction, psychological distress, body satisfaction, and self-esteem using standardized scales. All patients had the extent of alveolar bone loss classified according to Cawood and Howell's (1991) system during a clinical examination. The results indicated that the response of patients to implants or dentures was influenced by the degree of bone loss. Patients with extensive resorption who received implants appeared, from a psychological perspective, to receive more benefit than their nonimplant counterparts. Hence, there is some evidence to support the inclusion of clinical measures of alveolar bone loss when considering the psychological impact accruing from implant-based treatments.

Oral rehabilitation with implant-retained prostheses following ablative surgery and reconstruction with free flaps.

Ablative surgery of the oral tissues may result in significant facial deformity, poor oral function, and psychologic detriment. Immediate surgical reconstruction with vascularized free flaps has become increasingly popular, but the oral rehabilitation of these patients with conventional dental prostheses is usually unsuccessful. The results and clinical experiences of treating a group of 17 patients with ablative surgery, immediate reconstruction with free flaps, and restoration with mandibular implant-retained prostheses are presented after follow-up periods of 6 months to 7 years. Most patients expressed a high degree of satisfaction with their prostheses. General principles and guidelines for the provision of this effective treatment modality are discussed.
