The Cornell Interview of Peers and Friends: development and validation.

The Cornell Interview of Peers and Friends (CIPF), a 30-minute semistructured interview, evaluated 7- to 11-year-old children's perceptions of their social relationships. Significant differences on the CIPF were found between clinical and nonclinical groups and between boys and girls. Three CIPF subscales, Developmental Appropriateness, Social Skills, and Self-esteem, were assessed and significantly differentiated between clinical and nonclinical populations. Satisfactory interrater reliability is reported for the interview's total score and the three subscale scores. The CIPF offers potential for screening children at risk for emotional disturbance and for assessing outcomes of therapeutic interventions.

Child

Working through conflict with self-destructive preschool children.

This case history charts the treatment of a preschooler who first presented at the age of three years and ten months with aggressive and self-destructive behaviors. During the initial months of treatment, the therapist focused upon establishing a therapeutic alliance with the child in order to evoke a transference reaction. Compelling evidence of the transference in this case occurred in the ninth month of treatment when the therapist told the child that she would be going on vacation. The child, whose own mother had abandoned him several times, responded with uncharacteristic physical and verbal abuse. Although the child engaged in aggressive and self-destructive play enactments almost from the onset of treatment, these behaviors intensified from the fifth month of treatment onwards, as it became evident that he had entered the working-through phase. Aggressive impulses were shown in his manipulation of toys and other objects, and self-destructive episodes emerged in the child's incessant efforts to jump from chairs and tables, as well as in repeated threats to "shoot" himself with a toy gun. The therapist was sensitive to the child's need to continually repeat and gradually modify these behaviors. She permitted their display without exhibiting shock or alarm, but at the same time, expressed concern for the child's safety and reinforced this concern by setting limits on his unacceptable behavior. Gradually, the child's self-destructive and aggressive tendencies abated. Further evidence that the conflict had been worked through was also seen in the child's ability to express a more realistic assessment of his home environment, one which reconciled the conflict between "good" and "bad" impulses. This advancement in perception was demonstrated by the child's verbal recognition that while his mother was capable of doing "bad" things, she was still his mother and he loved her. Prior to the termination of treatment, both the child's grandmother and teachers reported significant improvement in the child's behavior and linguistic abilities.

Quantification of brainstem auditory evoked responses for patient monitoring.

A method of quantifying the integrity of the brain stem auditory evoked responses (BAERs) is applied to specific cases in both the ICU and OR to demonstrate its usefulness as an adjunct to peak latency evaluation. This measure is particularly valuable when peak identification is difficult as a result of poor waveform coherence. Examples are included to demonstrate that this method can also give independent information from peak latency.

Endocrine changes after laparoscopic ovarian cautery in polycystic ovarian syndrome.

Recently, laparoscopic ovarian cautery has been described as a method of ovulation induction in women with polycystic ovarian disease. In an attempt to determine the mechanism of action, serum levels of androstenedione, testosterone, luteinizing hormone, follicle-stimulating hormone, and estradiol were determined before and after the laparoscopic ovarian cautery in six women with polycystic ovarian disease who had failed to ovulate with clomiphene citrate and human chorionic gonadotropin. Six regularly cycling women undergoing laparoscopy for investigation of infertility or tubal ligation served as controls. In patients with polycystic ovarian disease but not in controls, serum androstenedione, testosterone, estradiol, and luteinizing hormone significantly decreased to nadir levels on postoperative days 3 and 4. In contrast follicle-stimulating hormone levels rose after operation. These results resemble those reported after ovarian wedge resection. Of the six treated women, five ovulated postoperatively and four conceived. Laparoscopic ovarian cautery appears to be a promising alternative treatment for patients with polycystic ovarian disease in whom initial medical management fails.

Response threshold determination of the brain stem auditory evoked response: a comparison of the phase versus magnitude derived from the fast Fourier transform.

An ensemble of 10 groups of brain stem evoked responses (BAERs), each consisting of 200 sweeps, was collected for different intensity levels and for a no-stimulus condition. A fast Fourier transform was calculated for the separate groups, which permitted a phase variance to be derived. The phase variance was compared to the magnitude value for selected frequency components making up the BAER. It was found that the phase variance was a better predictor of signal than magnitude. The superiority of prediction by phase results from intersubject variation being smaller for phase compared to magnitude.

Acoustic Stimulation

Characterization of self-stimulation elicited from rat dorsolateral pariaqueductal gray.

Rats were stereotaxically implanted with chronic bipolar electrodes aimed at the periaqueductal central gray (PCG) and were subsequently tested for intracranial self-stimulation (ICSS) behavior. Consistent and reliable ICSS behavior was elicited from both the midventral and dorsolateral portions of the PCG, the latter result occurring in loci previously reported as predominantly aversive. Midventral PCG ICSS rates were significantly higher than dorsolateral PCG ICSS rates. The higher rates were not accounted for by either current intensity used or motor artifacts. Moreover, both sites displayed reliable ICSS behavior characterized by regular low-variability rates and no seizure activity, seen with other brainstem ICSS sites, but unlike diencephalic and telencephalic ICSS behavior which is characterized by irregular bursts of responding which are highly variable and sometimes accompanied by seizures. The differential ICSS responsivity between PCG structures suggests that they may be mediated by different anatomically-localizable substrates.
