Twenty-one bone marrow transplantation (BMT) patients were studied prospectively to determine the prevalence of sonographic hepatobiliary abnormalities and to determine if these abnormalities were associated with hepatic venocclusive disease (VOD). Baseline US was performed in all patients prior to chemoradiation therapy, with follow-up ultrasound (US) examinations at the time of BMT and 14 days and 28 days after BMT. Sonograms were reviewed for the presence of ascites, gallbladder wall thickening, hepatosplenomegaly, hepatofugal flow, hepatic vein compression, increased periportal echogenicity, and increased hepatic echotexture. The baseline scans showed 13 of 21 patients (62%) with abnormalities prior to BMT. Within 2 weeks after BMT, serial US showed interval development of hepatomegaly in five patients (three with VOD and two without), gallbladder wall thickening in one (with VOD), hepatic vein compression in two (both with VOD), hepatofugal flow in one (without VOD), and ascites in one (with VOD). US scans obtained 4 weeks after BMT in 15 of the 21 patients showed even fewer new abnormalities. No sonographic finding was strongly associated with VOD. 相似文献

OBJECTIVE: To examine relations between condition severity and psychosocial functioning in 70 8- and 9-year-old pre-adolescents with spina bifida by testing several direct, indirect, and mediated effects models for proximal functional status and distal adjustment outcomes. METHODS: Proximal functional status outcomes (e.g., degree of involvement in activities, scholastic competence, athletic competence, attentional problems) and distal adjustment outcomes (e.g., behavior problems, social competence) were assessed with mother, father, and teacher report. Severity variables included spinal lesion level, spina bifida classification, shunt status, ambulation status, number of shunt surgeries, and two severity composites. RESULTS: Condition severity was associated with the proximal functional status outcomes across parent and teacher report. In contrast, no significant relationships were found between the severity parameters and distal adjustment outcomes. Findings supported a proximal effects model of condition severity as well as an indirect effects model (e.g., presence of a shunt-->less scholastic competence-->less social competence) and were consistent with recent theoretical formulations (e.g., Wallander & Varni, 1995). CONCLUSIONS: Disentangling proximal functional status outcomes and distal adjustment outcomes is critical in studies of condition severity and psychosocial functioning. We discuss clinical implications. 相似文献

Etidronate disodium (EHDP) therapy is often instituted emergently for treatment of hypercalcemia associated with malignancy, and a staging bone scan is part of the evaluation of the patient with extensive metastatic disease. In these patients in whom high dose EHDP therapy has been instituted, uptake of the bone scan agent is markedly diminished. The case presented illustrates this finding: a breast cancer patient who had received two 500-mg intravenous doses of EHDP prior to bone scan staging. No skeletal visualization was present at 3 hr after 99mTc-MDP injection. Blood-pool activity and uptake in large metastatic sites were observed. 相似文献

OBJECTIVE: To study coping socialization longitudinally by examining reported and observed family environment and parenting variables in relation to children's problem-focused coping in a sample of 68 families of preadolescents with spina bifida and 68 matched able-bodied comparison families. METHODS: Family environment and parenting variables were assessed with mother and father reports and observational measures. Children's problem-focused coping was self-reported. RESULTS: Prospective analyses revealed that maternal responsiveness, paternal responsiveness, and family cohesion predicted an increase in children's use of problem-focused coping strategies, while change in paternal responsiveness and maternal responsiveness and demandingness was related concurrently to change in coping. Few group (spina bifida vs. able-bodied) or gender differences with respect to parenting and family influences on children's coping behaviors were found. CONCLUSIONS: Multimethod findings suggest that the quality of parenting and family environment is associated with children's problem-focused coping behaviors. We discuss clinical implications. 相似文献

OBJECTIVE: To examine dyadic and systemic family functioning across several domains (conflict, cohesion, and stress) in families of preadolescents with spina bifida in comparison to families of able-bodied preadolescents (8- and 9-year olds; n = 68 in each sample). METHODS: Mother-, father-, and child-reported questionnaire data and observational ratings of family behavior were employed. RESULTS: Findings revealed significant group and socioeconomic status (SES) differences, particularly for the observational family data. Compared to families of able-bodied children, families in the spina bifida sample were less cohesive and children from this sample were more passive during family interaction tasks. Additional analyses suggested that some of these significant associations between group status and family functioning were mediated by verbal IQ, indicating that a significant portion (42%-55%) of the overall group effect was due to variations in child cognitive functioning. Lower SES families demonstrated higher levels of observed mother-child conflict, less observed and perceived family cohesion, and more life events. Lower SES families from the spina bifida sample appear to be particularly at risk for lower levels of family cohesion. CONCLUSIONS: Findings for the spina bifida sample support a resilience-disruption view (Costigan, Floyd, Harter, & McClintock, 1997) of systemic functioning in families of children with pediatric conditions. 相似文献

Computed tomography of air-space disease 总被引:1,自引:0,他引:1
Although computed tomography (CT) has not been used as often in air-space diseases as in interstitial ones, it often provides useful information. Diseases such as early opportunistic pneumonia may be detected by CT before becoming visible on plain radiographs. Also, extent and location are often better defined by CT than by plain radiographs. Accompanying abnormalities such as abscess, lymphadenopathy, and pleural effusion are often clearly demonstrated by CT. This article reviews the CT findings in a variety of air-space diseases, including pneumonia and other infections, radiation pneumonitis and fibrosis, embolism, eosinophilic pneumonia, alveolar proteinosis, bronchioloalveolar carcinoma, lipoid pneumonitis, sarcoidosis, and trauma. 相似文献
