[Pregnancies by fertilization in vitro. Biochemistry of the follicular fluid]. / Grossesses par fécondation in vitro. Biochimie du liquide folliculaire.

Fifty four follicular fluids containing 41 oocytes were sampled from 6 patients in which at least one pregnancy was obtained after IVF. Their biochemical composition has been correlated with the follicle maturity and oocyte quality. Three components have been assayed: steroids, prostanoids, proteolytic enzymes. Determinations of estrogens and total aromatisable androgens were carried out by the enzymatic technic of Nicolas and al.; progesterone and 17 OH progesterone by RIA. Development of in vitro cultured and fertilized oocytes appears to be improved when progesterone and estrogens concentrations in the follicular fluid are above 2 000 and 600 ng/ml respectively, with an A/E ratio under 1. On the other hand, prostanoids (T X B2, PGE2, PGF2 alpha determined by RIA) and proteolytic enzymes : (collagenolytic and kallikrein type activities) seemed related to ovulatory activity rather than to oocyte quality.

Patients' attitudes toward behavior therapy and psychotherapy.

A questionnaire survey of 50 patients treated by behavior therapy or short-term, analytically oriented psychotherapy revealed that both groups, as well as those patients who improved the most, placed a high value on insight, the patient-therapist relationship, catharsis, and trust. The findings suggest that behavior therapy patients tend to place more emphasis than do their therapists on factors that have traditionally been thought important in analytic psychotherapy.

Behavioural treatment of orgasmic dysfunction: a controlled study.

Twenty-two anorgasmic women received 20 sessions of a multiple-technique behavioural therapy. The design included blind ratings by two independent assessors, multiple assessment instruments, and a waiting list control group. Treatment was significantly better than no treatment in terms of: (1) the percentage of patients experiencing orgasm during at least 50 per cent of sexual relations; (2) the percentage of women reporting satisfactory sexual relations at least 50 per cent of the time; (3) patients' ratings of positive reactions to various sexual behaviours; and (4) assessors' global clinical ratings. Significant improvement was also noted on the MMPI, IPAT, and Symptom Check List. Improvement was maintained at a follow-up average 9 months later. These results support the impression that a behavioural approach offers much promise in treating female orgasmic dysfunction.

Differences between behavior therapists and psychotherapists.

Patient-therapist interaction patterns of three experienced behavior therapists and three matched analytically oriented therapists were compared. Each therapist saw ten patients in short-term individual therapy. The more active behavior therapists dominated the conversation in terms of speech time, more frequently offered explicit advice and instructions, gave more direct information, presented their own value judgments, and exerted greater control over the content of the interaction than did psychotherapists. Although both groups provided a warm and accepting atmosphere, behavior therapists showed higher levels of accurate empathy, interpersonal contact, and therapist self-congruence. Patients viewed behavior therapists as more authoritarian and believed that psychotherapists encourage greater independence. It was concluded that the two therapy approaches to patients were consistent with theoretical models of each.

Short-term analytically oriented psychotherapy versus behavior therapy.

Ninety-four outpatients with anxiety neurosis or personality disorder were randomly assigned for four months to a waiting list, behavior therapy, or psychoanalytically oriented therapy. The target symptoms of all three groups improved significantly, but the two treated groups improved equally well and significantly more than those on the waiting list. There were no significant differences among the groups in work or social adjustment; however, the patients who received behavior therapy had a significant overall improvement at four months. One year and two years after the initial assessment, all groups were found to be equally and significantly improved.
