The nuclear medicine bleeding scan is frequently insufficient to locate sites of bleeding precisely, in spite of its great sensitivity. A small, hand-held Geiger-Müller counter, placed directly on exposed intestine in the operating room, enables precise location of the probable bleeding site. In three patients, the technique allowed a minimal amount of intestine to be resected, distinguished between large- and small-intestinal hemorrhage, and eliminated other foci as sites of bleeding. 相似文献

A new device for the endovascular treatment of aneurysms is described. It consists of a guidewire-directed porous liner or bag, detachably mounted on a microcatheter and designed to be inserted into an aneurysm and to be filled with detachable coils or other embolic agents. Several prototypes have been made. Preliminary in vitro and in vivo experiments have demonstrated its behavior in relatively wide-necked aneurysms. 相似文献

Compacts weighing 40 mg and containing triamcinolone acetonide 70-90% and polyhydroxybutyric acid (PHB) 30-10% or poly (DL-lactic acid) 20% with a diameter of 5 mm were bonded onto the side-wall of molar teeth. In vitro dissolution studies showed the compacts to release 12% of drug in 30 days with an initial burst effect. Drug loading or polymer matrix type had little effect. In vivo studies in dogs showed that compacts containing 80% drug in PHB produced salivary levels of triamcinolone acetonide for 30 days. When evaluated in five patients with lichen planus resistant to conventional therapy, these compacts produce a slight clinical improvement in three subjects. Differential scanning calorimetry studies confirmed that the drug and polymer were present as a physical mix in these compacts. 相似文献

On child and adolescent inpatient psychiatric units, nursing staff have 24-hour exposure to patients, an excellent vantage point for observing behavior in a variety of situations and interpersonal contexts. How staff members respond to milieu behaviors depends in part on their judgment of what prompted a youngster's response and his/her ability to process the event and control the attendant emotions. To assess such aspects of a child or adolescent's presentation requires that staff appraise not just the presenting behavior but the patient's information-processing and affect-regulation abilities. One way this developmental knowledge can be embedded in practice is through assessment guides that contain observation cues for key issues related to how children/adolescents think, feel, and behave. This article sets down the rationale for the content and organization of such inpatient nursing assessment guides and suggestions for their dissemination to the unit staff. 相似文献

TOPIC: A triad of impairment that consists of impaired communication, impaired social skills and over-regulated behavior characterizes autism. Causality of autism is yet to be identified. Therapy has been devised to apply to the work with children and adolescents with a diagnosis of autism in the domains of impaired communication and impaired social skills. Little attention has been paid to the importance of the over-regulated behavior that forms part of the triad of impairment.
PURPOSE: This paper considers this point of over-regulation in the triad of impairment in autism through the lens of Chaos theory.
SOURCES: Contemporary literature on autism and Chaos theory.
CONCLUSIONS: Implications for nursing practice and research are raised. 相似文献

A nurse practitioner (NP) program to improve postpartum appointment keeping in an outpatient family planning clinic is described and evaluated. The subjects (N = 59) were non-high-risk obstetric patients prescheduled to be seen at 6 weeks postpartum by the NP. Two groups were identified by convenience sampling: Group A (n = 25), the nonintervention group, and Group B (n = 34), the intervention group. Two types of intervention were used: a postpartum telephone call after discharge (n = 11), or a predischarge postpartum visit (n = 23). Results suggest that those in the intervention group were more likely to keep their appointments (p less than .02); only the postpartum visit increased the probability of appointment keeping (p less than .05). 相似文献

We retrospectively analysed patients seen in a rapid referral clinic to
identify those with abnormalities genuinely requiring urgent assessment,
and to evaluate the impact of the clinic on routine services. After
advertising the availability of the service, 25% of telephone referrals
from primary-care physicians led to identification of patients considered
suitable for urgent evaluation. We assessed 350 patients over an 18-month
period. After neurological review, relevant abnormalities were identified
in 73%, and 33% were considered to have warranted urgent assessment. In
addition, 74% required radiological evaluation and 14% had a
neurophysiological procedure; 19.4% were admitted on the same day, 13%
underwent CSF analysis and 34% required some form of therapeutic
intervention. In retrospect, patients with a clinical history of > 11
days rarely warranted urgent referral. Visual failure and diplopia provided
the highest correlation with patients deemed to require urgent assessment,
and syncope and headache the lowest. Despite the number of patients
reviewed, no effect was demonstrated on waiting times for standard
out-patient review.

Single arm phase II study of oral vitamin B12 for the treatment of musculoskeletal symptoms associated with aromatase inhibitors in women with early stage breast cancer 下载免费PDF全文

Breast cancer patients receiving endocrine therapy with aromatase Inhibitors (AIs) often experience musculoskeletal and joint‐related side effects. The purpose of this study was to evaluate the effect of Vitamin B12 supplements on musculoskeletal symptoms such as pain and arthralgias induced by AIs and to correlate response with serum and inflammatory biomarkers. Upon receiving approval by the Institutional Review Board (IRB), the majority of the patients consented into the study were treated at the Texas Tech Breast Care Center. Included were patients who had a diagnosis of invasive breast cancer (Stages I‐III), and were experiencing significant musculoskeletal symptoms associated to AIs. Only patients with an average pain score ≥ 4, as assessed by the Brief Pain Inventory‐Short Form (BPI‐SF) questionnaire, were included in the study. Participants received 2500 mcg of sublingual vitamin B12 daily for 90 days. Assessments at baseline and at 3 months included: BPI‐SF pain scores, the impact on quality of life determined by Functional Assessment of Cancer Therapy–Endocrine Symptoms (FACT‐ES), and correlative serum markers relative to baseline (a pre‐post study). A total of forty‐one patients were enrolled. Average pain scores were improved by 34% (P < .0001) at 3 months compared to baseline. In addition, a 23% improvement in worst pain was noted (P = .0003). Analysis of the results for the FACT‐ES scoring showed improvement on all scales. No significant adverse events were observed. Decrease in pain score was correlated with increased serum B12 levels. This study suggests that Vitamin B12 reduces pain and improves quality of life for patients taking AIs who experienced AI‐related musculoskeletal symptoms. If confirmed in large randomized prospective trials, Vitamin B12 would be a safe and cost‐effective option for the treatment of AI‐related musculoskeletal symptoms. 相似文献
