PURPOSE: Adult survivors of childhood cancer have been an underserved and understudied population. Few clinics are available to take care of them, unlike the numerous ones that exist for children. The authors established a clinic that would take care of all survivors diagnosed before the age of 25 years, ensuring the participation of a significant number of adults. The authors observed that many adult patients came to their annual visits accompanied by one or both of their parents. The rate was almost three times as high compared with parents in either a primary care or subspecialty internal medicine clinic. METHODS: The authors investigated this phenomenon by asking parents of adult survivors to fill out a questionnaire that collected demographic information as well as reasons for parents accompanying their adult children to doctors' appointments. Open-ended comments were also solicited. RESULTS: Most parents who came with their adult survivor children did not accompany their other children to doctor visits and commented that they felt there was a unique bond created by the cancer experience that did not diminish with increasing age of their children. The rate of parental attendance was independent of diagnosis or demographic indicators. Many parents stated that they continued to be concerned about their child's diagnosis, overall health, and risk for cancer recurrence. DISCUSSION: Parents of adult survivors of childhood cancer may harbor deep feelings of protectiveness that continue well beyond the initial treatment and off-treatment periods when the threat of primary cancer recurrence is a realistic concern. This can be manifested in them by accompanying their adult children to doctors' appointments and deserves further study. 相似文献

OBJECTIVE: Exploration of the possibility that local injury of the endometrium increases the incidence of implantation. DESIGN: Prospective study. SETTING: Clinical IVF unit. PATIENT(S): A group of 134 patients, defined as good responders to hormonal stimulation, who failed to conceive during one or more cycles of IVF and embryo transfer (ET). INTERVENTION(S): The IVF treatment and ET were preceded by repeated endometrial biopsies, in a randomly selected 45 of a total of 134 patients. MAIN OUTCOME MEASURES: Outcome of IVF-ET treatments. RESULT(S): Transfer of a similar number of embryos (3.4 +/- 1.0 and 3.1 +/- 0.9 in the experimental and control patients, respectively) resulted in rates of implantation (27.7% vs. 14.2%, P =.00011), clinical pregnancy (66.7% vs. 30.3%, P =.00009), and live births per ET (48.9% vs. 22.5%, P =.016) that were more than twofold higher in the experimental group as compared to controls. CONCLUSION(S): These results suggest that IVF treatment that is preceded by endometrial biopsy doubles the chance for a take-home baby. 相似文献

BACKGROUND: Caudal regression syndrome (CRS) is a rare anomaly of the lower body pole that represents a continuum of congenital malformations ranging from isolated sacral agenesis to absence of the lumbosacral spine and major visceral anomalies. While the exact etiology of this syndrome is unclear, maternal diabetes, genetic factors, teratogens and vascular anomalies altering blood flow have been hypothesized to play a role in its pathogenesis. CASE: A fetus had extreme hypotrophy of the caudal body pole, aplasia of the lower spine and complete renal agenesis diagnosed in the second trimester by ultrasound. Maternal history revealed the use of minoxidil solution for preventing hair loss for four years prior to and during gestation. Also, the mother had taken trimethoprim-sulfamethoxazole during the first trimester for treatment of upper respiratory disease. No maternal diabetes or history of familial genetic diseases was evident. CONCLUSION: In an extreme form of CRS consisting of complete aplasia of the lower body pole and viscera and additional malformations, a possible drug-related etiology was suggested but should be confirmed by more studies. 相似文献

This study examined whether the soluble 66 and 51 kDa tumor-associated antigens (sTAA) could promote suppression by the anticancer drug 5-fluorouracil (5-Fu) of chemically induced mammary tumorigenesis, and which, if any, morphological changes in the immune organs accompany this treatment. Dimethylbenzanthracene (DMBA, 8 mg/rat, twice) was used to induce mammary tumors. After the appearance of many large tumors, the preparations of sTAA and 5-Fu, alone or in combination, were administered in weekly doses, for 4 weeks. The following groups of mammary tumor-bearing rats were studied: 1) control non treated rats, 2) rats treated with sTAA, 3) rats treated with 5-Fu, 4) rats treated with 5-Fu and sTAA. The experiment was terminated when tumors in 70% of control rats became ulcerous. Treatment with sTAA alone significantly decreased tumor yield and their total area relative to controls. Both of these parameters showed an even larger significant decrease after treatment with 5-Fu, and the most marked decrease was obtained after the combined treatment with 5-Fu and sTAA. Results demonstrated that not only do sTAA have tumor-suppressive properties, they also enhance the anticancer effects of 5-Fu and prevent its toxic side effects. Morphologically, the treatment with sTAA was manifested in a significant increase in the size of the spleen follicles and mantle layer compared to control rats with large tumors. The treatment with 5-Fu decreased the sizes of almost all areas of the spleen compared to control rats, whereas the combined treatment with 5-Fu and sTAA increased all these parameters to the levels found in rats treated with sTAA alone. The total areas of the cortex and paracortex in the lymph nodes increased after treatment with sTAA. Treatment with 5-Fu alone resulted in a significant decrease of these areas which, as seen in the spleen, increased after combined treatment with 5-Fu and sTAA. Similar changes were seen in the areas of the separate lymph node zones. We concluded that the addition of sTAA to conventional tumor chemotherapy regimens has a remarkable synergistic effect on mammary tumors leading to curative antitumor responses of the host's immune organs. 相似文献

Improved survival in women with BRCA-associated ovarian carcinoma 总被引:12,自引:0,他引:12
BACKGROUND: The objective of this study was to determine the clinical characteristics, treatment response, and frequency of p53 overexpression in Ashkenazi Jewish women with hereditary ovarian carcinoma. METHODS: Seventy-one Jewish women with epithelial ovarian carcinoma (EOC) were tested for the three BRCA founder mutations using single-strand conformation polymorphism analysis, heteroduplex analysis, and protein truncation testing. Clinical and histopathologic data were reviewed retrospectively. In vitro chemoresistance was analyzed in 32 patients. Mutations of p53 were studied using immunohistochemical detection of p53 overexpression. RESULTS: Thirty-four of 71 Jewish patients with EOC (48%) had germline BRCA mutations (BRCA heterozygotes), including 22 BRCA1 mutations and 12 BRCA2 mutations. BRCA heterozygotes were younger compared with Jewish patients who had EOC without mutations (sporadic carcinoma; 50 years vs. 59 years, respectively; P = 0.01). BRCA1 heterozygotes were younger compared with BRCA2 heterozygotes (48 years vs. 57 years, respectively; P = 0.01). Histopathologic tumor features were similar; however, tumors with low malignant potential were seen only in women with sporadic carcinoma. Both groups had equivalent rates of surgical cytoreduction and similar median follow-up (72 months). BRCA heterozygotes had higher response rates to primary therapy compared with patients who had sporadic disease (P = 0.01). In vitro chemoresistance predicted tumor response to platinum chemotherapy correctly in BRCA heterozygotes (P = 0.0096). BRCA heterozygotes with advance-stage disease had improved survival compared with patients who had advanced stage sporadic carcinoma (91 months vs. 54 months, respectively; P = 0.046) and had a longer disease free interval (49 months vs. 19 months, respectively; P = 0.16). p53 overexpression was common in BRCA heterozygotes (80%). CONCLUSIONS: BRCA1 heterozygotes developed EOC at a younger age compared with BRCA2 heterozygotes and women who had sporadic ovarian carcinoma. BRCA heterozygotes had a better response to platinum chemotherapy compared with women who had sporadic disease, which may have contributed to their improved prognosis. 相似文献

Gender role expectations of pain is associated with pain tolerance limit but not with pain threshold
Gender role expectations of pain (GREP) was suggested to predict sex differences in pain perception. Our aim was to explore sex differences in GREP and investigate its relationship with heat-pain threshold (HPT) and heat-pain tolerance limit (HPTL). University students (115 males, 134 females) filled the GREP questionnaire. HPT and HPTL were measured in a sample of 72 students. Additionally, GREP values of the present sample were compared with those of the original, American sample to explore possible cultural effects.Both males and females perceive themselves (and their own sex in general) to be less sensitive to pain and less willing to report of pain than the opposite sex. Males perceived themselves and other men, to endure pain relatively similar to women whereas females perceived themselves and other women as less endurable to pain than men. HPT was similar for the two sexes but males had higher HPTL than females. Within each sex, HPTL correlated mainly with self’s perception of pain sensitivity. The American and Israeli samples differed in that Israeli males and females presented stronger stereotypical views towards same and opposite sexes.Both males and females held stereotypical “macho” attitude towards themselves with regard to pain sensitivity and willingness to report of pain however only females held stereotypical, “macho” attitude towards themselves with regard to pain endurance. The sex differences in GREP and in HPTL and the correlations between GREP items and experimental thresholds suggest that the relationship between GREP and experimental pain is complex and sex-specific. It also appears that GREP is affected by culture. 相似文献

A developmental fMRI study of the Stroop color-word task 总被引:9,自引:0,他引:9
We used fMRI to investigate developmental changes in brain activation during a Stroop color-word interference task. A positive correlation was observed between age and Stroop-related activation (n = 30) in the left lateral prefrontal cortex, the left anterior cingulate, and the left parietal and parieto-occipital cortices. No regions showed a negative correlation between activation and age. We further investigated age-related differences by stratifying the sample into three age groups: children (ages 7-11), adolescents (ages 12-16), and young adults (ages 18-22). Young adult subjects (n = 11) displayed significant activation in the inferior and middle frontal gyri bilaterally, the left anterior cingulate, and bilateral inferior and superior parietal lobules. Between-group comparisons revealed that young adults had significantly greater activation than adolescent subjects (n = 11) in the left middle frontal gyrus and that young adults showed significantly greater activation than children (n = 8) in the anterior cingulate and left parietal and parieto-occipital regions, as well as in the left middle frontal gyrus. Compared to children, both adult and adolescent subjects exhibited significantly greater activation in the parietal cortex. Adult and adolescent groups, however, did not differ in activation for this region. Together, these data suggest that Stroop task-related functional development of the parietal lobe occurs by adolescence. In contrast, prefrontal cortex function contributing to the Stroop interference task continues to develop into adulthood. This neuromaturational process may depend on increased ability to recruit focal neural resources with age. Findings from this study, the first developmental fMRI investigation of the Stroop interference task, provide a template with which normal development and neurodevelopmental disorders of prefrontal cortex function can be assessed. 相似文献

PURPOSE: The aim of this study was to explore the nursing role in education and follow-up of patients who were taking oral chemotherapy (CT) and to identify the worldwide gap in patient education about oral CT. MATERIALS AND METHODS: Multinational Association of Supportive Care in Cancer members were invited to participate in a survey on oral CT. Nurse coordinators collected data via a 16-item questionnaire. Respondents totaled 1115 oncology nurses from 15 countries. RESULTS: Findings showed that about half of subjects work in outpatient/ambulatory clinics and had given at least two or more oral CT drugs. Although 52% had some type of guidelines/protocols, 47% reported not having received any education about oral CT drugs. While 64% report being involved in patient education, 58% of subjects indicated lack of patient education materials that are specific for oral CT agents. Only 27% stated that they gave all necessary information such as when and how to take the drugs, drug safety and storage, side effects, and symptom management. Reasons for not being involved in oral CT education and follow-up included beliefs that the physician plans the oral CT and gives patients necessary instructions (34%), that nurses only see patients who receive intravenous chemotherapy (16%), that nurses have lack of knowledge about oral agents (15%), and belief that physicians are responsible for patient follow-up. The nurses suggested better education and follow-up of patients to include the written patient education materials (33%) and professional education for nurses (30%). CONCLUSIONS: Findings revealed the need for professional education for nurses to ensure comprehensive, consistent patient education and development of written materials for patients receiving oral CT treatment. 相似文献
