Antisynthetase syndrome (aSS) corresponds to an overlapping inflammatory myopathy identified by various myositis-specific autoantibodies (directed against tRNA-synthetases). Myocardial involvement in this condition is poorly described.From a registry of 352 aSS patients, 12 cases of myocarditis were retrospectively identified on the basis of an unexplained increase in troponin T/I levels associated with either suggestive cardiac magnetic resonance imaging (MRI) findings, nonsignificant coronary artery abnormalities or positive endomyocardial biopsy.The prevalence of myocarditis in aSS is 3.4% and was not linked to any autoantibody specificity: anti-Jo1 (n = 8), anti-PL7 (n = 3), and anti-PL12 (n = 1). Myocarditis was a part of the first aSS manifestations in 42% of the cases and was asymptomatic (n = 2) or revealed by an acute (n = 4) or a subacute (n = 6) cardiac failure. It should be noted that myocarditis was always associated with an active myositis. When performed (n = 11), cardiac MRI revealed a late hypersignal in the T1-images in 73% of the cases (n = 8). Half of the patients required intensive care. Ten patients (83%) received dedicated cardiotropic drugs. Steroids and at least 1 immunosuppressive drug were given in all cases. After a median follow-up of 11 months (range 0–84) 9 (75%) patients recovered whereas 3 (25%) developed a chronic cardiac insufficiency. No patient died.The prevalence of myocarditis in aSS is similar to that of other inflammatory myopathies. Although the prognosis is relatively good, myocarditis is a severe condition and should be carefully considered as a possible manifestation in active aSS patients. 相似文献

OBJECTIVE: To assess the incidence of clinically identified hepatitis B cases, as well as the demographic and risk behaviour profiles of these cases in a defined Canadian population. METHODS: An enhanced hepatitis surveillance system was established in October 1998 to identify acute hepatitis B and C cases in Canada. Acute and likely acute cases, as determined by laboratory testing, collectively defined incident clinical hepatitis B cases. Data from 1999 to 2002 on incidence, demographic characteristics and risk behaviour characteristics were collected and analyzed. RESULTS: During the 1999 to 2002 surveillance period, 379 cases were identified in a target population ranging from 3,128,179 to 8,576,071 individuals. The observed hepatitis B incidence rate was 1.93/100,000 person-years in the surveillance area. The incidence rate was 2.74 times higher in men. The observed incidence rates decreased for all age groups over the surveillance period but remained high in the 20- to 29-year-old and 30- to 39-year-old age groups, as well as in men. Of the incident cases, 55.9% self-identified as being born in Canada and 18.5% as being born in Asia, while 18.7% did not identify a birth area. Of the Canadian-born cases, 61.3% identified themselves as Caucasian, 11.3% as Aboriginal and 23.6% as no ethnic category. Injection drug use was the most reported risk behaviour (19.1%), followed closely by sex-associated risk behaviours. A large proportion, 24%, indicated none of the known risk behaviours. CONCLUSIONS: The hepatitis B incidence rate has shown some decrease in the surveillance population from 1999 to 2002 and this may be due, in part, to past intervention programs (eg, vaccination programs and health promotion campaigns). The authors' results identify some high-risk groups that would benefit from additional prevention and control programs, and further targeted research and intervention. 相似文献

Bilateral vestibular schwannoma (BVS) is the hallmark of neurofibromatosis type 2 (NF2), both of them being present at diagnosis. We report four cases of metachronous BVS, a contralateral intracanalicular vestibular schwannomas (VS) being visible 2 to 13 years after resection of a unilateral VS. NF2 workup was negative except in one case where two NF2 gene mutations were found in tumor analysis. These cases raise the questions of whether the contralateral VS occurred by chance and how to manage it on the only hearing ear. Otologists should be aware of this rare eventuality for decision making of the first unilateral VS. Laryngoscope, 131:E250–E254, 2021 相似文献

Purpose
This study analyzed the current approaches for rectal cancer treatment in elderly patients.Methods
We retrospectively studied 240 rectal cancer patients who had undergone radiotherapy from 2000 to 2008. The ages of the patients ranged from 65 and 75 years (group A, n?=?127) and older than 75 years (group B, n?=?113). The distribution of the Charlson comorbidity index was similar between the two groups, but the ECOG performance status (PS) differed between the groups (66 % of the patients of group A were PS 0, and 40 % were PS 0 in group B (p?<?0.0001)). The tumor stages were comparable between groups.Results
The median age of the patients was 74.3 years (range 65–90.6). Treatment was discussed during a multidisciplinary cancer team meeting before treatment for 55 % of the cases in group A and 73 % of the cases in group B (p?<?0.001), and treatment proposals were in accordance with guidelines in 96 % of the cases in group A and 76 % of the cases in group B (p?<?0.001). Group B patients received slightly less concurrent chemotherapy (35 vs. 30 % for group A; p?=?0.54), more hypofractionated radiotherapy (41 vs. 54 % for group A; p?=?0.064), less surgery (92 vs. 80 % for group A; p?=?0.014), and less adjuvant chemotherapy (34 vs. 10 % for group A; p?<?0.001). Finally, 80 % of the patients in group A and 60 % of the patients in group B received treatment in accordance with guidelines (p?=?0.007) and in the logistic regression model. Non-metastatic patients who were aged below 75 years were predicted for conformal management (HR?=?0.323; 95 % CI?=?0.152–0.684) irrespective of their performance status, comorbidity, or disease stage.Conclusions
Treatment proposals and administered therapy differed according to age. 相似文献637.
Colorectal cancer screening for average‐risk adults: 2018 guideline update from the American Cancer Society 下载免费PDF全文

In the United States, colorectal cancer (CRC) is the fourth most common cancer diagnosed among adults and the second leading cause of death from cancer. For this guideline update, the American Cancer Society (ACS) used an existing systematic evidence review of the CRC screening literature and microsimulation modeling analyses, including a new evaluation of the age to begin screening by race and sex and additional modeling that incorporates changes in US CRC incidence. Screening with any one of multiple options is associated with a significant reduction in CRC incidence through the detection and removal of adenomatous polyps and other precancerous lesions and with a reduction in mortality through incidence reduction and early detection of CRC. Results from modeling analyses identified efficient and model‐recommendable strategies that started screening at age 45 years. The ACS Guideline Development Group applied the Grades of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria in developing and rating the recommendations. The ACS recommends that adults aged 45 years and older with an average risk of CRC undergo regular screening with either a high‐sensitivity stool‐based test or a structural (visual) examination, depending on patient preference and test availability. As a part of the screening process, all positive results on noncolonoscopy screening tests should be followed up with timely colonoscopy. The recommendation to begin screening at age 45 years is a qualified recommendation. The recommendation for regular screening in adults aged 50 years and older is a strong recommendation. The ACS recommends (qualified recommendations) that: 1) average‐risk adults in good health with a life expectancy of more than 10 years continue CRC screening through the age of 75 years; 2) clinicians individualize CRC screening decisions for individuals aged 76 through 85 years based on patient preferences, life expectancy, health status, and prior screening history; and 3) clinicians discourage individuals older than 85 years from continuing CRC screening. The options for CRC screening are: fecal immunochemical test annually; high‐sensitivity, guaiac‐based fecal occult blood test annually; multitarget stool DNA test every 3 years; colonoscopy every 10 years; computed tomography colonography every 5 years; and flexible sigmoidoscopy every 5 years.

Worldwide, breast cancer is the most frequent neoplasm and the second leading cause of cancer death amongfemales. It dominates in both developed and developing countries and represents a major public health problem. Theetiology is multifactorial and involves exogenous agents as well as endogenous factors. Although they account for onlya small fraction of the breast cancer burden, mutations in the BRCA1 and BRCA2 genes are known to confer a highrisk predisposition. Mutations in moderate/low-penetrance genes may also contribute to breast cancer risk. Previousstudies have shown that mutations in the CHEK2 gene are involved in breast cancer susceptibility due to its impacton DNA repair processes and replication checkpoints. This study was conducted to evaluate the frequencies of threegermline mutations in CHEK2 gene (c.1100delC, R145W and I157T) in breast cancers in Rwanda. Using direct DNAsequencing, we analyzed 41 breast cancer patients and 42 normal breast controls but could not detect any positives.CHEK2 mutations may be a rare event in Rwandan population and may only play a minor if an role in breast cancerpredisposition among familial and sporadic cases. 相似文献

Inflammatory skin diseases including atopic dermatitis (AD) and psoriasis (PSO) are underpinned by dendritic cell (DC)–mediated T cell responses. Currently, the heterogeneous human cutaneous DC population is incompletely characterized, and its contribution to these diseases remains unclear. Here, we performed index-sorted single-cell flow cytometry and RNA sequencing of lesional and nonlesional AD and PSO skin to identify macrophages and all DC subsets, including the newly described mature LAMP3+BIRC3+ DCs enriched in immunoregulatory molecules (mregDC) and CD14+ DC3. By integrating our indexed data with published skin datasets, we generated a myeloid cell universe of DC and macrophage subsets in healthy and diseased skin. Importantly, we found that CD14+ DC3s increased in PSO lesional skin and co-produced IL1B and IL23A, which are pathological in PSO. Our study comprehensively describes the molecular characteristics of macrophages and DC subsets in AD and PSO at single-cell resolution, and identifies CD14+ DC3s as potential promoters of inflammation in PSO. 相似文献
