The purpose of this work is to identify the place where the father is at the time his son/daughter is being born and his perceptions about this place. This study has a qualitative nature and the Minayo's (1996) reference of speech analysis is used. In order to do it, twenty-three fathers whose children have been born within the present year were interviewed. The approach was direct and they were interviewed in public places. We verified that only seven fathers were present at the moment of parturition, and that among them, only one had his wife's delivery assisted by the SUS. The other interviewed fathers were absent from their children's birthplace. The conclusion is that in spite of all the encouragement given to the father by the correspondent bibliography to be present at the moment of his children's birth for a precocious father-baby interaction, reality shows us that, especially in hospitals where one can be assisted by the SUS, men are excluded from this very important moment. 相似文献
Two family aggregation studies report the occurrence and co-occurrence of oral language impairments (LIs) and reading impairments (RIs). Study 1 examined the occurrence (rate) of LI and RI in children with specific language impairment (SLI probands), a matched control group, and all nuclear family members. Study 2 included a larger sample of SLI probands, as well as their nuclear and extended family members. Probands and their family members who met specific criteria were classified as language and/or reading impaired based on current testing. In Study 1, the rates of LI and RI for nuclear family members (excluding probands) were significantly higher than those for control family members. In the SLI families, affected family members were more likely to have both LI and RI than either impairment alone. In Study 2, 68% of the SLI probands also met the diagnostic classification for RI. The language and RI rates for the other family members, excluding probands, were 25% and 23% respectively, with a high degree of co-occurrence of LI and RI (46%) in affected individuals. Significant sex ratio differences were found across generations in the families of SLI probands. There were more male than female offspring in these families, and more males than females were found to have both LIs and RIs. Results demonstrate that when LIs occur within families of SLI probands, these impairments generally co-occur with RIs. Our data are also consistent with prior findings that males show impairments more often than females. 相似文献
We attempt to demonstrate that physicians overdiagnose loxoscelism (colloquially known as 'brown recluse spider bites') by comparing the numbers of such diagnoses to the historically known numbers of Loxosceles spiders from the same areas in four western American states. The medical community from non-endemic Loxosceles areas often makes loxoscelism diagnoses solely on the basis of dermonecrotic lesions where Loxosceles spiders are rare or non-existent. If these diagnoses were correct then Loxosceles populations should be evident, specimens should readily be collected over the years and there should be a reasonable correlation between diagnoses and spider specimens. In 41 months of data collection, we were informed of 216 loxoscelism diagnoses from California, Oregon, Washington and Colorado. In contrast, from these four states, we can only find historical evidence of 35 brown recluse or Mediterranean recluse spiders. There is no consistency between localities of known Loxosceles populations and loxoscelism diagnoses. There are many conditions of diverse etiology that manifest in dermonecrosis. In the western United States, physician familiarity with these conditions will lead to more accurate diagnoses and subsequent proper remedy. 相似文献
: To evaluate survival and patterns of recurrence in patients with primary central nervous system germinoma treated with radiation therapy.
: Data regarding 48 patients with histologically confirmed, primary central nervous system germinoma were reviewed. All had been operated on at the Mayo Clinic between the years 1935 and 1993. Thirty-two patients (67%) were treated since 1973. The study group included 39 males and 9 females, with a median age at diagnosis of 17 years (range, 6–42 years). Twelwe patients (25%) were treated with craniospinal axis irradiation, 11 (23%) received whole-brain irradiation without spinal axis irradiation, and 24 (50%) underwent partial-brain irradiation. Treatment volumes were unknown in one patient. The median dose to the primary tumor was 44.00 Gy (range, 7.44–59.40 Gy). The median follow-up was 5.5 years (range, 4 months to 37 years).
: Actuarial 5-year and 10-year survival for the entire study group of patients was 80%. There was a trend toward improved survival in patients treated after 1973 (introduction of computed tomography) with 5-year and 10-year survival of 91% vs. 63% in prior years (p = 0.07). For the group of 31 patients treated since 1973 with known treatment volumes, the spinal axis failure rate at 5 years was 49% for patients treated with partial brain fields (11 patients) vs. 0% for those having undergone whole brain (10 patients) or craniospinal axis (10 patients) irradiation (p = 0.007). The rate of brain failure was also significantly higher in patients receiving less than whole-brain irradiation; at 5 years, 45% of the patients treated with partial-brain fields had intracranial recurrence of disease compared to 6% of patients treated with craniospinal axis or whole-brain irradiation (p = 0.01). Among the 32 modern era patients, the rate of brain failure was higher in patients who received doses less than 40 Gy (median dose, 48.55 Gy; range, 30.60-59.40 Gy) to the primary tumor (5-year brain failure rate 52% vs. 11%, p = 0.002).
: The long-term survival of patients with histologically proven CNS germinoma treated with radiation is excellent. Whole-brain or craniospinal axis irradiation appears to result in fewer spine and brain failures than does partial-brain irradiation. Furthermore, the administration of doses greater than 40 Gy to the primary tumor is associated with better local control. 相似文献
Prominent neuronal differentiation and MYCN amplification occur only in a small percentage of medulloblastomas (primitive neuroectodermal tumor of the cerebellum). In this article, we describe two medulloblastomas that showed a striking degree of neuronal differentiation with islands of mature neurons associated with abundant neuropil. In these differentiated foci, there were no mitoses or atypia, and the histology was reminiscent of a malformative or hamartomatous lesion. Both tumors were assessed for MYCN amplification by the novel technique of differential polymerase chain reaction (PCR) and fluorescent in situ hybridization (FISH). In case 1, MYCN amplification was in the 10 - fold range determined by differential PCR, while in case 2 the level of amplification was marked, with 20 - 30 copies compared with diploid controls. FISH analysis also confirmed the presence of MYCN amplification in both tumors. These two cases are of great interest, especially as they show MYCN amplification in medulloblastomas with marked degree of neuronal differentiation. Furthermore, in both cases, there was evidence of a slower and more indolent clinical course, suggesting a more favorable outcome in medulloblastoma with this degree of neuronal differentiation. 相似文献
Objective: This analysis was performed to examine the outcome of adult and pediatric patients with brainstem tumors. Methods and materials: Forty patients with brainstem glioma were evaluated retrospectively. Included were 24 females and 16 males ranging in age from 3 to 81 years (median, 29.5 years). These patients were treated with various combinations of surgery, chemotherapy, and ratiotherapy (RT). The length of follow-up in survivors ranged from 0.6 to 20 years (median: 3.2 years, mean: 6 years). Survival rates were calculated with the Kaplan Meier method and differences between survival curves were calculated using the log-rank test. Results: The overall 2 and 5-year survival rates were 44% and 34%, respectively. The median survival time was 19 months. The 5-year survival rate was 54% for patients with tumors outside the pons compared to 21% for those with tumors involving the pons (p=0.04). The 5-year survival rate was 59% for patients with exophytic tumors as compared to 23% for those with intrinsic tumors (p=0.05). Patients undergoing subtotal resection had a 5-year survival rate of 53% compared to 28% for those having only a biopsy or no surgical intervention (p=0.04). None of the other potential prognostic or treatment related factors evaluated [patient age, tumor grade, tumor histology, radiotherapy parameters (including BID fractionation, 3-D treatment planning, or the use of doses > 55 Gy), or the administration of adjuvant chemotherapy] evaluated were associated with patient survival. Conclusions: Brainstem gliomas generally occur in younger individuals. The survival rates were better for patients with exophytic tumors, those involving sites other than the pons, and tumors amenable to subtotal resection. Improvements in the outcome of patients with brainstem gliomas will require new therapeutic approaches. 相似文献
CONTEXT: Chronic hepatitis C infection (CHCI) is an increasingly common problem, affecting about 2% of the US population. The cost and complexity of treatment and difficulties in communicating with the infected population are of concern to insurers and health planners. PURPOSE: To describe the clinical features of patients with CHCI in a rural Medicaid-covered population and to describe a method developed for treating CHCI in an underserved rural community. METHODS: We developed a disease management approach to patients with CHCI receiving insurance coverage through a Medicaid HMO in rural Oregon. A locally based multidisciplinary hepatitis committee was formed to develop a management protocol and a process for selecting patients for treatment. The committee met monthly to develop the treatment plan for individual patients. Day-to-day treatment was provided by a nurse under the supervision of the committee. FINDINGS: One hundred forty-three adults with CHCI were identified by their primary care physicians. About half the patients had a type 1 genotype. Treatment with pegylated interferon and ribavirin was completed on 21 persons, 11 (52%) of whom had a virologic cure. Problems with treatment toxicity were common. Patient satisfaction with the treatment by the nurse was high. CONCLUSIONS: CHCI is common in this rural, nonminority Medicaid-insured population. A locally based disease management model was developed that was well received by patients and was successful in delivering a high quality of care for people with CHCI in a rural area. 相似文献
The prevalence and persistence of adolescent substance use and abuse is a national health issue, and substance use among adolescents is frequently comorbid with other psychiatric disorders. Most studies in this area utilize samples of middle or high school students or from inpatient settings. Less is known about substance use and psychiatric comorbidity among delinquent adolescents. The present study examined data from two cohorts of juvenile offenders collected over a 2-year period (n = 245, n = 299). Participants reported frequency of cigarette, alcohol, marijuana, and other substance use. Participants' parents completed a measure of behavior problems. Path analyses suggested that parental reports of externalizing problems were significantly related to self-reported substance use while parental reports of internalizing problems were not. Results also suggested that smoking and alcohol use act as mediators between externalizing problems and marijuana and other drug use. Although there were some mean differences by gender, the pattern of relationships amongst the variables did not differ by gender. Implications of the findings and future directions are discussed. 相似文献
