Objective:To determine whether photos or silhouettes are adequate methods for evaluating the esthetic profiles of black subjects and whether black and white evaluators have different preferences for esthetic profiles.Materials and Methods:One photographic record of the profile of a black female patient with accentuated dental bimaxillary dentoalveolar protrusion was randomly selected. The image of the patient''s profile was altered to produce a series of seven photos and seven silhouettes (a total of 14 images) with different lip positions but uniform distances in relation to the esthetic plane created by Ricketts (line E). Fifty black and 50 white lay evaluators were invited to enumerate the photos and silhouettes, produced according to the lip position, in the order in which they considered most esthetically pleasing.Results:The number of preferences found to be within the esthetic norm was slightly higher among the photographs than among the silhouettes; the esthetic profile with a deviation of −2 mm from line E was elected as the most attractive, and the esthetic pattern with a deviation of +6 mm from the normal line E was considered the least attractive. There were no statistically significant differences between the preferences related to the variables race, sex, and educational background.Conclusions:The esthetic attractiveness of the facial profiles of black subjects in photos and silhouettes was evaluated in a similar manner among black and white evaluators. Among both black and white evaluators, the greatest preference was for the slightly concave profile, which was within the limit considered standard. 相似文献

BACKGROUND: There is a paucity of information regarding prostate cancer (PCa) risk factors among Hispanics, the fastest-growing ethnic group in the United States. METHODS: This population-based case-control study included 176 Texas men of Mexican descent with PCa and 174 age- and ethnicity-matched controls. Demographic, lifetime occupational history, family history of cancer, lifestyle (e.g., smoking, alcohol, diet, and recreational physical activity) and anthropometric information were collected by personal interviews. Chemical exposure and physical activity were determined using job-exposure matrices for each reported job. RESULTS: Logistic regression models adjusted for relevant covariates were used to evaluate their independent effects. Compared to controls, cases were three times more likely to work in jobs with high agrichemical exposure (OR = 3.44, 95% CI 1.84-6.44), and 54% less likely to work in jobs with moderate/high occupational physical activity (OR = 0.46, 95% CI 0.28-0.77). In analyses stratified by stage, cases with organ-confined PCa were three times more likely to have high agrichemical exposure (OR = 3.39, 9%CI 1.68-6.84), and 56% less likely to have moderate/high levels of occupational physical activity (OR = 0.44, 95% CI 0.26-0.76). Increased risk of being diagnosed with advanced PCa was associated with obesity at time of diagnosis (OR = 2.50, 95% CI 1.20-5.20) and high levels of agrichemical exposure (OR = 4.65, 95% CI 1.97-10.97), but not with occupational physical activity. CONCLUSIONS: This case-control study, the first conducted in a homogeneous Hispanic population, identified modifiable PCa risk factors, such as physical activity and agrichemical exposure, which may be useful in developing interventions for this understudied population. 相似文献

It is well known that reactions are commonplace occurrences during the course of leprosy disease. Stigmatization may even be attributable to reactions which are also responsible for the worsening of neural lesions. A cohort of 162 newly-diagnosed baciloscopically positive patients from the Leprosy Care Outpatient Clinic of the Oswaldo Cruz Foundation (FIOCRUZ) was selected for this study. While 46% of the multibacillary (MB) patients submitted to the 24 fixed-dose multidrug therapy (MDT) regimen suffered reactions during treatment, it was found that all MBs were susceptible and that constant attention and care were required at all times. Fourteen per cent were classified as BB, 52% as BL, and 33% as LL. None of the variables under study, such as, sex, age, clinical form, length of illness, length of dermatological lesions, baciloscopic index (BI), or degree of disability proved to be associate with reaction among the patients studied. Reversal Reaction (RR) occurred in 45%, and Erythema Nodosum Leprosum (ENL) occurred in 55%. Among BB patients who developed reactions (15 patients), 93% presented RR; while among the LL patients who developed reactions (34 patients), 91% presented ENL. Likewise, ENL was very frequent among those with disseminate lesions, while RR was most often observed in patients with segmentary lesions. RR was also most likely to occur during the initial months of treatment. It was demonstrated that the recurrence rate of ENL was significantly higher than that of RR. Neither grade of disability nor BI was shown to be associated with RR and ENL reaction. However, the RR rate was significantly higher among patients showing BI < 3, while ENL predominated among those patients with BI > 3. 相似文献

A comparative study was made of the initial and final bacterial indices (BIs) of 213 MB leprosy patients who had been administered 12-dose (Group 1/128 patients) and 24-dose (Group 2/85 patients) World Health Organization multi-drug therapy to measure the effectiveness of both treatment regimens. All patients were evaluated at the beginning of treatment, at 12 months, and again after 24 months had elapsed. Decline in BI values and average BIs at 24 months were found to be similar for both groups. Moreover, no statistical difference between the two treatment regimens was found in the frequency rate of reaction. 相似文献

Treatment of established recurrent hepatitis C in liver-transplant recipients with pegylated interferon-alfa-2b and ribavirin therapy 总被引:13,自引:0,他引:13
Neff GW Montalbano M O'Brien CB Nishida S Safdar K Bejarano PA Khaled AS Ruiz P Slapak-Green G Lee M Nery J De Medina M Tzakis A Schiff ER 《Transplantation》2004,78(9):1303-1307
INTRODUCTION: The management issues of transplant patients with hepatitis C virus (HCV) are complex, and interferon therapy is often ineffective. We present data from a retrospective review in liver-transplant recipients suffering from HCV recurrence that were treated with pegylated alpha-2b interferon and ribavirin. METHODS: A retrospective review of transplant recipients that received combination pegylated alpha-2b interferon (1.5 mcg/kg/wk) and ribavirin (400-600 mg/day) therapy intended for at least 48 weeks. Complications were recorded and included neutropenia (<750 cells), anemia (hemoglobin <8 g) with and without treatment consisting of blood transfusions, erythropoietin, or dose reduction of ribavirin, and depression. The diagnosis of HCV recurrence was determined by an increase in liver chemistries, histopathologic findings with inflammation along with viral recurrence using the COBAS AMPLICOR HCV test. RESULTS: Fifty-seven liver-transplant recipients were included, 29 naive (group 1) to therapy and 28 nonresponders (group 2) to at least 6 months of interferon and ribavirin therapy. Eight (27.6%) patients in group 1 and six (21%) patients in group 2 were HCV nondetectable at the end of 48 weeks of therapy. Ribavirin therapy was decreased in 13 of 29 (45%) for group 1 and 11 of 28 (39%) in group 2. Therapeutic interventions were 4 of 57 (7%) blood transfusions, 23 of 57 (40%) erythropoietin, and 17 of 57 (30%) filgrastim. CONCLUSION: Combination pegylated interferon with ribavirin appears to effective therapy in HCV recurrence and in HCV nonresponsive to interferon and ribavirin. This data reveals the difficulty and caution that must be taken when treating HCV-R liver-transplant recipients with combination pegylated alpha-2b interferon and ribavirin therapy. 相似文献

A qualitative study, with eleven nurses studying obstetric nursing in Teresina-PI, the objectives of which were to describe their knowledge and practice of measures to control breast cancer and to discuss the practice of self-examination by nurses. A focus group was used as technique. The results show death or mutilations, followed by a bad prognosis, such as significances associated with breast cancer. They mentioned control measures such as healthy habits and examinations, especially self-examination, mammography, ultrasonography, clinical, static and dynamic examination, and biopsy in the confirmation of malignancy. Among the guidelines provided to customers, self-examination, healthy food habits, physical activity and no addictions were the most important ones. It can be concluded that these professionals did not perform self-examination very often, but the majority had healthy food habits. 相似文献

Clear cell lesions of the urinary tract often present diagnostic challenges. We report a previously undescribed lesion in the prostate, occurring in a 73-year-old man who presented with hematuria and subsequently underwent transurethral resection of the prostate. A total of 24 g of tissue was removed, and in 4 of 17 blocks submitted a lesion morphologically and immunohistochemically similar to clear cell carcinoma of the kidney was noted. A thorough cystoscopic and full-body, radiologic workup was performed, but no renal tumor was discovered. Random cystoscopic biopsies of the bladder and prostatic urethra as well as bladder washings were benign. Subsequent needle biopsies of the prostate were also benign. The patient underwent a pelvic lymph node dissection with radical cystoprostatectomy and orthotopic Studer pouch diversion. There was organ-confined, ordinary-type prostatic adenocarcinoma (Gleason's 3 + 3) present bilaterally in the peripheral zone; no residual clear cell carcinoma was identified. All lymph nodes were negative, and the urinary bladder showed no dysplasia or neoplasia. We think this tumor represents a primary renal type of clear cell carcinoma arising in the prostate. To our knowledge, this type of tumor has not been previously reported to arise in an extrarenal location. 相似文献

Alemtuzumab (Campath-1H) combined with tacrolimus in intestinal and multivisceral transplantation 总被引:15,自引:0,他引:15
Tzakis AG Kato T Nishida S Levi DM Tryphonopoulos P Madariaga JR De Faria W Nery JR Regev A Vianna R Miller J Esquenazi V Weppler D Ruiz P 《Transplantation》2003,75(9):1512-1517
BACKGROUND: We combined alemtuzumab (Campath-1H, Berlex Laboratories, Montville, NJ) and tacrolimus (Tac) immunosuppression for intestinal and multivisceral transplantation. MATERIALS AND METHODS: A total of 21 adult patients received 24 grafts: 14 intestinal, nine multivisceral, and one liver-intestinal graft. Alemtuzumab was administered perioperatively in four doses with low-dose Tac (levels 10-15 ng/dL) and no maintenance steroids. Tac was substituted with sirolimus in case of Tac-related complications. Suspected or mild rejections were treated with steroids. Moderate rejections were treated with steroids or OKT3. Severe rejections were treated with OKT3. RESULTS: Of the 16 patients that were followed up for an average of 9 months, 12 are alive with functioning grafts. Two patients experienced severe rejection, three experienced moderate rejection episodes, and seven experienced mild acute rejection episodes. Four patients never developed acute rejection. Infectious complications included a cytomegalovirus enteritis and four fungal infections (related to central venous access). CONCLUSIONS: The combination of alemtuzumab and Tac therapy without steroid use seems to efficiently prevent acute rejection in a significant number of patients without causing frequent opportunistic infections. 相似文献
