A community-based public-academic liaison program

OBJECTIVE: The authors discuss obstacles and incentives associated with successful community-based public-academic liaison activities and illustrate their conclusions by describing their public-academic liaison program, which received the American College of Psychiatrists' first annual Award for Creativity in Psychiatric Education. METHOD: The first 8 years of a state/university collaboration are described in which the parties involved first developed a variety of innovative services designed to fill specific gaps in the public service delivery system and subsequently integrated academic research and training components. RESULTS: The carefully planned and monitored process resulted in the exponential growth of interest in public sector work, the realization of the university's primary goals of developing high quality training and research sites, a substantial increase in the number of graduates accepting positions in the public sector, several projects funded by the National Institute of Mental Health, and two national awards. CONCLUSIONS: These collaborations illustrate the highly complementary relationship of public-academic liaison activities and their potential capacity to improve access to services, substantially improve the quality of these services, generate extramural support for services research, and increase the number of well-trained professionals in the public sector.     

Effects of variability of practice in a movement-education program on motor skill performance

The study investigated the effects of the direct and exploration methods of teaching on the overhand throwing performance of kindergarten children. Variable throwing practice was provided in the exploration method by allowing children to throw 5 different types of balls at a variety of targets. Children given the direct method threw only one type of ball and received specific instruction and demonstrations. Throwing for distance and throwing accuracy were measured on pre- and posttests. A novel throwing task was administered on the posttest to measure skill transfer. The experimental groups received instruction three times per week for 4 wk. in throwing while a control group received no instruction. Significant sex differences in throws were found for distance and accuracy. Analysis of data from the novel task gave no significant effects. The two methods of teaching did not produce different levels of throwing skill.     

The uptake of porphyrin and zinc-metalloporphyrin by the primate prostate

The relative distribution of sensitizer drugs in the prostate and its contiguous organs is of importance in the treatment of localized prostatic cancer with photodynamic therapy. Using the primate model, whose prostate is both morphologically and physiologically homologous with its human counterpart, the distribution of hematoporphyrin derivative (HpD) amongst organs of urological interest was determined. Hematoporphyrin derivative levels were comparatively low in both caudal and cranial prostatic lobes (0.93-1.77 micrograms/g) and were similar to those in rectum, urethra and the skin. The reticuloendothelial organs, liver, spleen and also the kidney accumulated the highest quantities of porphyrin (4.76-9.8 micrograms/g, liver > spleen > kidney). Despite a high avidity of prostatic tissue for zinc, a zinc-metalloporphyrin (Zn-HpD) did not concentrate selectively in the prostate. The results are of clinical value in view of the homology between the primate and the human.     

Screw fixation of the olecranon after fracture or osteotomy

For 10 years prior to the availability of the Olecranon Screw described in this article, oblique fixation using a regular Sherman bone screw was employed for displaced fractures (with a suitable fragment) by engaging the anterior ulnar cortex. Internal fixation was supplemented by a split for 3 weeks. The reason for a special olecranon screw is to eliminate the necessity for additional fixation and permit early motion. No instance of non-union or important restriction of motion or serious complication has been encountered.     

Initial and follow-up brain MRI findings and correlation with the clinical course in Wilson's disease

We performed pretreatment brain MRIs in 25 patients with neurologically symptomatic Wilson's disease (WD) and clinical and MRI follow-up in 16 of them. All 25 pretreatment MRIs revealed abnormalities, with abnormal high-signal intensity (HSI) in bilateral thalami being the most common (92%). HSI lesions in the brainstem (84%) and the basal ganglia (72%) were also common. Brain atrophy was present in 88% of the 25 patients. In the follow-up period of 5 to 24 months, during which the patients were treated with D-penicillamine, both HSI lesions and neurologic symptoms improved in 88% of the 16 patients, but the brain atrophy did not change.

A date with death: management of time-based and contingent suicidal intent

OBJECTIVE: The patient who voices suicidal intent in terms of the future or in terms of certain life contingencies presents special difficulties for the therapist. The authors outline the challenges posed by this problem for assessment, clinical management, and risk management. METHOD: The authors examined and analyzed case examples from both clinical and risk-management aspects. RESULTS: Problematic cases can be grouped into categories that offer insight as to management. The authors discuss this area and offer suggestions for appropriate clinical responses to this challenge. CONCLUSIONS: The authors recommend that therapists 1) treat the expressed "date with death" as a communication to be explored, 2) explore the problem of helplessness while monitoring their own countertransference responses, 3) assess the patient's competence to inform clinicians about suicidal state, and 4) readily use involuntary commitment.
