The use of the MMPI for the differentiation of suicidal and non-suicidal depressions.

The MMPI profiles of forty suicidal and forty non-suicidal male and female depressed patients, matched for age, were compared. Significant differences between MMPI scale T scores which showed some sex specificity were found between the suicidal and non-suicidal depressives. These results replicate previous findings. However neither individual scale T scores, derived discriminant functions, nor actuarial or cluster analysis-derived MMPI profiles could completely discriminate between suicidal and non-suicidal depressed inpatients of either sex. The relevance and implications of these findings to the ascertainment of suicidal risk are discussed.

Educational achievement, IQ and affective disorder in the adult offspring of bipolar manic-depressives.

An educational history, corroborated by records where available, was obtained on 54 of the 58 adult offspring of 17 bipolar manic-depressives. The offspring were also interviewed and psychiatric status was ascertained. Primary and other affective disorder in the offspring was not associated with a lower IQ or lower ultimate educational attainment than that of the remaining offspring. There was a trend towards increased educational failure in the offspring with primary affective disorder, but they were as likely as other offspring who had failed to have resumed their education at a later date. III offspring with any form of school failure had a significantly earlier onset of their psychiatric illness, although school failure could not be shown to be a part of an early symptom complex.

Psychiatric illness in the adult offspring of bipolar manic-depressives.

Forty-eight of the 50 living adult offspring of 16 bipolar patients were interviewed. Data was available on the 2 other offspring, who had previously suicided. One half of the offspring met criteria for psychiatric illness, the majority of which was either primary affective or other affective disorder. The mean age of onset of illness was middle to late adolescence, earlier than that generally reported elsewhere. Female offspring were 3 times as likely to be ill as male offspring, in spite of being equally represented in the sample. Reasons for this were examined.

Interviewing bipolar patients and their families.

The authors report on the case ascertainment phase of a pedigree study of patients with bipolar affective disorder. The nature of the research interview, which necessarily probes for symptoms and signs of affective disorder, appeared to have a provocative effect on some subjects by exposing heavily defended conflicts related to the expression of affect. Although such studies are necessary, researchers must be sensitive to the needs of their subjects and not regard the ascertainment interview as benign and uncathected.

Early symptoms of bioplar affective psychosis: research and clinical implications.

Review of the available literature shows that BP psychosis rarely reveals itself earlier in life, either by alternate psychiatric illness or by impairment in educational or occupational achievement. There is some evidence from early onset cases that the illness can evolve slowly but systematic studies are lacking. The possibility is raised that what was previously regarded as a premorbid "affective" (cyclothymic or hypomanic) personality may represent the early stages of the illness itself. This view requires prospective validation. Some research implications are discussed.

Providing dental treatment for patients with cardiovascular disease.

The appropriate management of dental patients with cardiovascular disease is contingent on appropriate assessment and evaluation. Baseline vital signs, a good medical history and medical evaluation are all essential for the safe delivery of care. All patients with cardiovascular disease can be managed using the following guidelines: 1. Properly assess the patient. This should include an assessment by the dentist and also a medical consultation if required. 2. Establish what medications the patient is taking along with the dose and timing and note any potential drug interactions and side effects. 3. Use short appointments (less than one hour), preferably in the morning. 4. Premedication should be considered to alleviate anxiety. The intraoperative use of nitrous oxide and oxygen is also a reasonable strategy for patients with cardiovascular disease, particularly those with ischemic heart disease. 5. Effective local anesthesia is important in order to avoid undue stress during the appointment as long as the guidelines for the administration of epinephrine are followed. The use of epinephrine impregnated gingival displacement cord should be strictly avoided in patients with cardiovascular disease. 6. For patients with angina pectoris, a fresh supply of nitroglycerin should be available at the time of the appointment. Prophylactic nitroglycerin has been shown to be effective in the prevention of both hypertension and angina pectoris during dental treatment. The appointment should be terminated early if the patient becomes overly anxious. In the event of cardiovascular symptoms during dental treatment, all work should be stopped. Emergency measures should be instituted if necessary. Preparations for emergencies should be undertaken by all dentists. The treatment of patients with cardiovascular disease is relatively simple if the proper steps are taken. The use of blood pressure measurements on all patients will help to screen for undiagnosed hypertension and all patients who are potentially hypertensive should be referred for medical evaluation. A preventive approach to the treatment of these patients will serve to prevent untoward outcomes and provide safe and simple delivery of dental care for cardiovascular patients.
