Odontodysplasia. Report of two cases and review of the literature.

Odontodysplasia is a rare developmental anomaly affecting the tooth structures in both deciduous and permanent dentitions. The enamel is thin and uneven in thickness, and the detinal tissue surrounds very large pulp chambers. Denticles are present in the pulp organ. The maxilla is involved twice as frequently as the mandible. Most of the affected teeth are in the anterior segments; however, all other teeth can be affected. The cause is unknown. Because of the tendency of the affected teeth to develop abscesses, the most common treatment is extraction. Two additional cases are reported, and the literature is reviewed.

Dental fluorosis associated with hereditary diabetes insipidus.

Among the characteristics of hereditary pituitary diabetes insipidus are polydipsia and polyuria from early infancy. Drinking of large amounts of water, even with lower than accepted fluoride content, can produce fluorosis of the teeth. A mother and her four children affected by this disorder presented different degrees of fluorosis directly related to the stage at which hormonal therapy was introduced.

Prediction of body composition in habitually active middle-aged men.

In 45 physically active men (ages 35-67 yr) who underwent hydrostatic weighing to determine body composition, multiple regression equations were developed for the prediction of body density (D), lean body weight (LBW), fat body weight (FBW), and % fat using selected anthropometric measurements. The prediction accuracy for these parameters using several previously generated anthropometric regression equations was also determined. With equations developed from the present data a substantially higher correlation was obtained between measured and predicted LBW (r = 0.95) than between measured and predicted D (r = 0.85), FBW (r = 0.88), or % fat (r = 0.84). When previously developed equations were applied to the present sample, correlations between measured and predicted values were considerably lower (4-42%) than in the original studies; this reduction was least in the case of LBW. Analysis of previous data indicated that in selected populations total body weight can account for a relatively large fraction of the variance in LBW. LBW may be estimated quite accurately (r greater than or equal to 0.90) in physically active men with one of several regression equations which include total body weight as an independent variable.

Some dynamic and transactional aspects of family theraphy with psychotic patients.

The application of family therapy to families with psychotic patients involves both technical and theoretic observations and underpinnings. The implications of these for the understanding of certain family dynamics and the use of family therapy in general are investigated. The rhythm of real participation and observation on the therapist's part and the utilization of co-therapists is contrasted with a more authoritarian, 'director' model of intervention. Tendencies in these families towards frozenness and immobility, as well as splitting and chaos, must be counteracted, and are reflected in interactions and transactions between co-therapists. The importance of unravelling these patterns and aiding therapists in the framework of a specially designed, ongoing supervisory seminary is stressed.

[Histological examinations on the hemostatic effect of freezing during surgical procedures in the head and neck (author's transl)].

In the course of surgical interventions 28 tissue blocks of muscle, subcutis, submaxillary gland and tumors were frozen in situ, using liquid nitrogen and a closed cryoprobe. Specimens were taken before freezing, immediately after thawing, 5 minutes and 30 to 60 minutes later. They were fixed in formaline, embedded in paraffine and stained with hematotoxylineosin and after Ladewig, for better diagnosis of a possible microthrombosis. Comparing the specimens taken before and after freezing we found: no reactive vasoconstriction but dilatation, no remarkable changes of vascular wall, a moderate edema of the connective tissue, abundant bleeding, only in two of 84 sections singular microthrombi. That means no reliable criteria of an hemostatic effect of CRYOSURGery could be found histologically within the first postoperative hour, at least in case of freezing during conventional surgery.
