Incontinence and troublesome behaviors predict institutionalization in dementia.

Factors predicting the early institutionalization of demented patients were studied in 143 outpatients using univariate and multivariate life-table methods. Four types of factors were evaluated for prognostic value: severity of functional impairment, behavioral disorders, individual patient characteristics, and type of caregiver. After follow-up of 19 +/- 12 months, 51 patients had been institutionalized. Increased global severity of dementia, the presence of troublesome and disruptive behaviors, and incontinence increased the likelihood of institutionalization. The best predictors of institutionalization were paranoia, aggressive behavior, and incontinence. Neither individual patient characteristics (age, education, and gender) nor caregiver relationship to the patient (male spouse, female spouse, and male or female child) influenced institutionalization. Since troublesome behavioral disorders are potentially treatable aspects of dementia leading to institutionalization, their management should be a major focus of therapy in dementia.     

D-cycloserine augmented exposure therapy for obsessive-compulsive disorder.

BACKGROUND: D-cycloserine (DCS), a glutamatergic partial N-methyl-d-aspartate (NMDA) agonist, can facilitate extinction learning related to cued fear in animals and humans. We predicted that DCS would accelerate obsession-related distress reduction in patients with obsessive-compulsive disorder (OCD) undergoing extinction-based exposure therapy. METHODS: We administered DCS (125 mg) or placebo in a double-blind fashion to individuals with OCD approximately 2 hours before each exposure session. RESULTS: D-cycloserine decreased both the number of exposure sessions required to achieve clinical milestones and the rate of therapy dropout. After four exposure sessions, patients in the DCS group reported significantly greater decreases in obsession-related distress compared with the placebo group; however, after additional sessions, the placebo group tended to catch up. CONCLUSIONS: D-cycloserine augmentation has the potential to increase the efficiency, palatability, and overall effectiveness of standard exposure therapy for OCD.     

Acute suppurative parotitis in a patient on total parenteral nutrition

A report of a patient who developed acute suppurative parotitis while on total parenteral nutrition for small bowel fistula is presented. The importance of early detection of parotitis as a cause of fever is emphasized. Attention to oral hygiene and early resumption of oral intake, whenever possible, are to be encouraged.     

Evaluation of a learning resource center for cancer patients

To address cancer out-patients' needs for information, a self-servelearning resource center was established at a nearby hotel.This facility provides numberous written and audio-visual cancerinformation materials for out-patients being treated at theUniversity of Texas M.D.Anderson Cancer Center Houston, Texas.Over a three month period, we conductred a consumer profileand assessed consumer satisfaction and use of the learning resuorcecenter. Data were gathered primarily through a self-administeredpatient/family satisfaction questionnaire and through monthlyadministrative records. The primary variables associated withuse of the learning resource center were educational level andhow long one had been a patient at the M.D.Anderson Cancer Center.Respondents who had used the learning resource center also indicateda stronger preference for receiving information about cancerthrough written materials than those who had not used the center.Users’ degree of satisfaction with the learning resourcecenter was generally high. The case study presented here offersrecommendations for the practitioner regarding the establishmentand evaluation of a learning resource center for cancer out-patientsand addresses these issues in a unique program setting.     

Spina Bifida: The Transition into Adulthood Begins in Infancy

Many concerns surround the preparation of a person with spina bifida for a successful transition into adult life and responsibilities. A model of intervention must be based on developmental concerns and timely issues from infancy through all stages of development to young-adult life. This article discusses, within a developmental framework, issues of transition in relation to physical, social, emotional, and educational/vocational needs; it also presents a conceptual framework for the transition into adulthood. Guidelines were developed by incorporating expected outcomes of people with spina bifida and using a philosophical framework that encompasses the achievement of a balance among dependence, independence, and interdependence. This model is based on developmental issues from infancy through all stages of development to young-adult life. Using this framework for care, the rehabilitation nurse can feel confident that the needs of clients with spina bifida and similar chronic conditions are being met.     

Ibotenic acid-induced lesions of the medial zona incerta decrease lordosis behavior in the female rat

To examine the role of the medial zona incerta (mZI) in female sexual behavior, ovariectomized estrogen- and progesterone-treated female rats were tested for sexual receptivity after bilateral injections of the selective neurotoxin ibotenic acid (3 micrograms/0.3 microliter) directly into the mZI. These injections produced a significant attenuation of lordosis behavior in highly receptive females when compared with saline-injected controls. This decrease in sexual receptivity was also reflected in a significant increase of rejections of male mount attempts. However, these lesions did not abolish the display of lordosis behavior. In addition, the frequency of hopping and darting was decreased in ibotenic acid-injected females when compared with controls. Consistent with previous studies, these lesions also produced a transient impairment of drinking behavior (hypodipsia) typical of rats with large electrolytic lesions of the mZI. This study demonstrates that mZI neurons play a role in mediating sexual receptivity in the female rat. Collectively, these results suggest that in addition to the projection from the ventromedial nucleus of the hypothalamus to the midbrain central gray, the functional integrity of the mZI is of crucial importance for the expression of sexual receptivity in the female rat.
