Enhancing Continuity of Care: Residency Training in an Integrated Inpatient--Partial Hospital Program.

This paper describes a teaching/service model that integrates inpatient, partial hospital, and intensive outpatient treatment. In this model, individual multidisciplinary treatment teams retain responsibility for a patient's care for any or all of three levels of intensity of services accessed during an episode of illness. This teaching/service model allows residents to follow patients for an average of 2.5 weeks across an entire acute episode of care compared with the 7.3 days of the average inpatient stay at the inpatient facility. The opportunity to continue treatment in step-down settings over longer periods of time allows residents and medical students to develop a fuller understanding of their patients. The authors believe that this continuum-care service model more efficiently trains residents in multiple aspects of psychiatric practice and provides patients with better care than the traditional inpatient-care service model.

Divalproex in the management of neuropsychiatric complications of remote acquired brain injury.

A retrospective chart review was conducted on 11 patients with a remote history of acquired brain injury (ABI) referred for psychiatric treatment who were treated with divalproex sodium alone or in combination with other psychotropic medications. The patients were highly heterogeneous. They had a variety of psychiatric symptoms and frequently received concomitant psychotropic medications. The mean daily dose of divalproex was 1,818+/-791 mg/day, serum valproic acid level 85.6+/-29.6 microg/ml. Mean Clinical Global Impression improvement score was 1.9+/-0.5. This is the largest postacute case series reported. It demonstrates that divalproex sodium is well tolerated and effective in reducing a broad range of neurobehavioral symptoms in psychiatric patients with a remote history of ABI.

Agitation, aggression, and disinhibition syndromes after traumatic brain injury.

Traumatic brain injury (TBI) is frequently complicated by disinhibition and aggression. These often profound changes in personality, present obstacles to rehabilitative treatments and community reentry. Syndromal presentations may involve a loss of impulse control, spontaneous aggression, and dysphoric bipolar states. Common neuropathological findings of inferior frontal lobe dysfunction support both disinhibition and kindling models of TBI-induced aggression. Assessment of these highly disruptive symptoms requires detailed historical, clinical, and neuropsychological information to formulate appropriate strategies. Management of TBI-related aggression may involve pharmacological, environmental, and psychotherapeutic strategies that incorporate caregiver training and support.

Sural Nerve Interposition Grafting during Radical Prostatectomy.

In 1997, autologous sural nerve grafting to reconstruct bilaterally resected cavernosal nerves was successfully performed in patients undergoing radical retropubic prostatectomy. After 12 months, one third of these patients had erections sufficient for intercourse. Since that time, patients who have had neurovascular bundle resection and sural nerve grafting have continued to show promising results. For example, within one large cohort of men who had unilateral, nerve-sparing radical prostatectomy, significantly more men who had sural nerve grafting regained potency, and did so in less time, than men who did not have grafting. More importantly, however, with better predictions of the presence of extracapsular disease, nerve-sparing surgery can be performed more selectively, reserving wide resection and sural nerve grafting for patients likely to have extracapsular extension. A multicenter, randomized clinical trial is needed to substantiate the positive outcomes observed with sural nerve grafting.

Regulation of coiled-coil assembly in tropomyosins.

Tropomyosins (TMs) are a family of actin filament-binding proteins. They consist of nearly 100% alpha-helix and assemble into parallel coiled-coil dimers. In vertebrates, TMs are encoded by four genes that give rise to at least 17 distinct isoforms through the use of alternative RNA splicing and alternative promoters. We have studied various aspects of the coiled-coil interactions among muscle and nonmuscle isoforms by the use of transfection of epitope-tagged constructs, followed by immunoprecipitation, SDS-PAGE, and Western blot analyses. For coiled-coil interactions between high-molecular-weight isoforms (284 amino acids), the information for homo- versus heterodimerization is contained in large part within the alternatively spliced exons of nonmuscle and muscle (skeletal and smooth) isoforms. Furthermore, sequences located in alternatively spliced exons encoding amino acids 39-80 (exons 2a/2b), amino acids 189-213 (exons 6a/6b), and amino acids 258-284 (exons 9a/9d) are critical for the selective formation of homo- versus heterodimers. Among low-molecular-weight isoforms (248 amino acids), TM-4 and TM-5 can form either homodimers or heterodimers. The trigger sequence (amino acids 190-202) is required for homodimerization of TM-4, but not heterodimerization of TM-4 with TM-5. How the dimeric state of TMs might play a role in their cellular localization and function is discussed.
