Protocol for the prevention and treatment of oral sequelae resulting from head and neck radiation therapy. 总被引:5,自引:0,他引:5

In addition to the desired antitumor effects, head and neck radiation therapy induces damage in normal tissues that may result in oral sequelae such as mucositis, hyposalivation, radiation caries, taste loss, trismus, soft-tissue necrosis, and osteoradionecrosis. These sequelae may be dose-limiting and have a tremendous effect on the patient's quality of life. Current policies to prevent these sequelae primarily are based on clinical experience and show great diversity. A protocol for the prevention and treatment of oral sequelae resulting from head and neck radiation therapy, based on fundamental research and data derived from the literature, is presented. The protocol is particularly applicable in centers with a dental team. This team should be involved at the time of initial diagnosis so that a successful preventive regimen is an integral part of the overall cancer treatment regimen. 相似文献

The CTLA-4 gene region of chromosome 2q33 is linked to, and associated with, type 1 diabetes. Belgian Diabetes Registry 总被引:8,自引:1,他引:8

Susceptibility to autoimmune insulin-dependent (type 1) diabetes mellitus
is determined by a combination of environmental and genetic factors, which
include variation in MHC genes on chromosome 6p21 (IDDM1) and the insulin
gene on chromosome 11p15 (IDDM2). However, linkage to IDDM1 and IDDM2
cannot explain the clustering of type 1 diabetes in families, and a role
for other genes is inferred. In the present report we describe linkage and
association of type 1 diabetes to the CTLA-4 gene (cytotoxic T lymphocyte
associated-4) on chromosome 2q33 (designated IDDM12). CTLA-4 is a strong
candidate gene for T cell- mediated autoimmune disease because it encodes a
T cell receptor that mediates T cell apoptosis and is a vital negative
regulator of T cell activation. In addition, we provide supporting evidence
that CTLA-4 is associated with susceptibility to Graves' disease, another
organ- specific autoimmune disease.

OBJECTIVE: Little is known about the relationship between lachrymal and salivary gland involvement in Sj?gren's syndrome (SS). It is also of interest to know which eye test contributes most to the diagnosis of SS. We investigated the performance of different tear tests and how these tests relate to common serologic and salivary tests in SS. METHODS: In patients suspected of SS, the tear breakup time and the tear mucus score were evaluated in addition to the routine tests. Eighty consecutive patients were included, categorized into primary SS (pSS), secondary SS (sSS), and negative for SS. RESULTS: The tear breakup time and mucus score both performed insufficiently in diagnosing SS, in contrast to the Rose Bengal score. In pSS and sSS patients, a clear correlation was noted between tear and saliva quality and secretion rate, and between the Rose Bengal score and parotid sialography. Increased Rose Bengal scores also correlated significantly with hyperglobulinemia and presence of SSB antibodies in serum, with duration of subjective eye dryness, and with decreased tear gland function. CONCLUSION: The Rose Bengal score remains the eye test of choice having the highest specificity for SS. Hyperglobulinemia and especially positive SSB serology may warrant close monitoring of the eyes, since these serum findings appear to relate to the severity of ocular surface damage. Theoretically, a positive evaluation of either the ocular or oral component, in addition to positive serology or histopathology, could be sufficient to diagnose the syndrome for clinical purposes. 相似文献

Objectives:To assess the diagnostic accuracy of two smartphone cephalometric analysis apps compared with Viewbox software.Materials and Methods:Pretreatment digital lateral cephalograms of 50 consecutive orthodontic patients (20 males, 30 females; mean age, 19.1 years; SD, 11.7) were traced twice using two apps (ie, CephNinja and OneCeph), with Viewbox used as the gold standard computer software program. Seven angular and two linear measurements, originally derived from Steiner cephalometric analysis, were performed.Results:Regarding validity, intraclass correlation coefficients (ICCs) ranged from .903–.983 and .786–.978 for OneCeph vs Viewbox and CephNinja vs Viewbox, respectively. The ICC values for intratool reliability ranged from .647–.993. None of the CephNinja measurements was below the recommended cutoff values of ICCs for reliability.Conclusions:OneCeph has a high validity compared with Viewbox, while CephNinja is the best alternative to Viewbox regarding reliability. Smartphone apps may have a great potential in supplementing traditional cephalometric analysis. 相似文献
