目的 探讨绝经后女性脊柱骨质疏松症的发病率,了解跟骨骨密度(bone mineral density,BMD)变化与脊柱骨质疏松症的相关性,分析跟骨骨量检测在判断脊柱骨折疏松症中的价值。方法 选择门诊,单纯性腰背疼痛、无外伤史、胸腰椎x线影像学显示有典型脊柱骨质疏松的绝经女性患者48例,年龄为29-84岁采用HK-I单光子骨密度仪(SPA)检测其跟骨的骨矿密度和骨量。结果 跟骨骨量112.82-486.42mg/cm^2,平均272.69mg/cm^2。其中,跟骨骨质疏松30例,平均骨量为201.85mg/cm^2;低骨量9例,平均273.13mg/cm^2;正常骨量9例,平均401.77mg/cm^2。与X线影像学相比较,脊柱骨质疏松的符合率为62.5%,大致符合率18.8%,有效符合率81.3%,不符合率18.8%。结论 SPA跟骨BMD仅可作为拟诊脊柱骨质疏松症的参考指标,临床参考价值为62.50%,其符合率与年龄递增相关。故诊断尚不能完全依赖跟骨密度检测参数,尤其75岁以下女性患者,仍需X线影像学的支持。非体力劳动者发病率相对较高,女性非体力劳动者尤其应注意预防。  相似文献

骨质量与骨量   总被引:5,自引:0,他引:5  
骨强度同时反映骨量与骨质量的完整性。骨强度由骨材料、构筑、力学性能及骨量共同构成。骨质量能解释一些单纯用骨量或骨密度(BMD)不能解释的问题,诸如在正常BMD仍发生骨折;给予抗骨吸收制剂后,虽只有小的面积骨密度(aB—MD)变化也能减少骨折风险;应用氟化物虽能增加脊柱BMD,但并不能减少脊柱骨折风险;骨折风险早在BMD最大变化之前即可出现等。  相似文献

Summary: In an extensive survey involving 2176 goats 1.56% of goats manifested clinical lesions of ringworm infection. Animals below the age of 6 months were affected most (4.20%). The incidence of infection was higher during the winter months. T. verrucosum, T. mentagrophytes and M. gypseum were isolated from the skin scrapings of 12, 4, and 2 goats respectively. It is suggested that the infected animals could be a source of disease to human population in which the zoophilic dermatophyte invasion is characterized by severe inflammatory lesions of the skin. The zoonotic importance of different dermatophytes is stressed.
Zusammenfassung: In einer ausgedehnten Untersuchung an 2176 Ziegen wurden bei 1,56% klinische Zeichen einer Hautmykose festgestellt. Tiere, die jühger als 6 Monate alt waren, zeigten mit 4,20% am häfigsten Krankheitssymptome. In den Wintermonaten war die Erkrankungshäufigkeit am gröBten. T. vermcosum, T. mentagrophytes and M. gypseum wurden jeweils von 12,4 bzw. 2 Ziegen isoliert. Die inflzierten Tiere köinnen eine Infektionsquelle für die menschliche Bevölkerung darstellen und dort Mykosen mit stark entzündlichen Veränderungen auslösen. Die Bedeutung verschiedener Dermatophyten als Erreger von Zoonosen wird hervorgehoben.  相似文献

Zygomycosis, or mucormycosis, is associated with significant morbidity and mortality in both children and adults. Studies in adults have shown an increase in the incidence of zygomycosis, particularly among haemtopoietic stem cell transplant (HSCT) recipients and patients with haematologic malignancies. There is a paucity of data on the epidemiology of zygomycosis in children. We performed a retrospective analysis to describe trends in zygomycosis between 1 January 2003 and 31 December 2010. We used the Pediatric Health Information System (PHIS) database to identify paediatric patients who were diagnosed with zygomycosis during the study period. Administrative data on diagnoses, demographics, underlying conditions and clinical experiences were collected. Summary statistics were calculated and tests for trend were conducted. We identified 156 unique patients with zygomycosis. The prevalence of zygomycosis did not significantly increase over time (P=0.284). The most common underlying condition was malignancy (58%) and over half received intensive care. Voriconazole utilisation among all hospitalised children significantly increased during the period (P=0.010). Our study demonstrates that the incidence of zygomycosis is not significantly increasing. During the time period there was a significant increase in the use of voriconazole among children.  相似文献

Lysosomes are a promising therapeutic target for induction apoptosis in cancer cells due to lysosomal membrane permeabilization (LMP) leading to leakage of hydrolytic enzymes, especially the cathepsins, into the cytoplasm. We hypothesized that with the modification of the ceramide-loaded liposomes with transferrin (Tf), we would achieve both tumor targeting and increased delivery of lysosome-destabilizing agents, such as ceramides to lysosomes, to initiate LMP-induced apoptosis. We prepared Tf-modified (TL) and plain (PL) liposomes and loaded with short (C6)- or long (C16) N-acyl chain ceramides. Uptake, intracellular localization of liposomes, stability of the lysosomal membrane and release of cathepsin D were investigated on Hela cells by fluorescence microscopy and flow cytometry. Apoptosis was evaluated by binding of fluorescently-labeled Annexin V. Antitumor and pro-apoptotic effects of C6Cer-loaded Tf-liposomes were demonstrated in vivo in an A2780-ovarian carcinoma xenograft mouse model. TL were internalized specifically via the TfR-dependent endocytic pathway and localized within the endosome-lysosomal compartment. Ceramide-loaded Tf-liposomes significantly increased apoptosis compared with ceramide-free and ceramide-loaded non-modified liposomes. The treatment of cancer cells with TL led to increased LMP and cytoplasmic relocation of the intralysosomal cathepsin D. A strong antitumor and pro-apoptotic effect of C6Cer-loaded TL was also demonstrated in vivo in an A2780-ovarian carcinoma xenograft mouse model. The lysosomal accumulation of ceramides delivered by Tf-liposomes initiates the permeabilization of the lysosomal membranes required for the release of lysosomal cathepsins into the cytoplasm and initiation of the cancer cell apoptosis both in vitro and in vivo.  相似文献

Bericht über das Auftreten von Hautmykosen bei Tieren auf der Farm der Landwirtschaftlichen Fakultät der Universität Assiut. Von 70 Kälbern waren 42 pilzkrank, davon 22 durch T. mentagrophytes, 20 durch T. verrucosum. Von 180 Kühen waren 8 pilzbefalien, sämtlich durch T. mentagrophytes. Von 2 kranken Bullen wurde T. verrucosum isoliert. Auch die 3 Pferde und 2 Maultiere der Farm waren pilzinfiziert; Erreger war in diesen Fällen T. equinum. Auch ein Kalb war von T. equinum befallen. Die gleiche Pilzart wurde ferner von 3 Tierpflegern isoliert, die Pilzherde am Hals und an den Armen aufwiesen.  相似文献

Objective The aim of this study was to investigate the changes in dietary preferences in cancer patients in China and to determine the need for encouraging the adherence to a sensible diet among such patients.Methods A total of 468 cancer patients were interviewed using a self-designed questionnaire focusing on changes in the intake of specific foods. Data were analyzed using SPSS 16.0. Results Most patients completely avoided roosters and carp(73.1%), condiments(51.9%), and meat of aquatic species(40.4%). All other types of the specific foods were completely avoided by different subpopulations of the patients.Conclusion In addition to focusing on disease treatment, medical professionals need to help cancer patients overcome barriers associated with the customs of avoiding specific foods encompassed by the term ”fawu” and provide them with dietary guidance in order to prevent negative nutritional effects.  相似文献

Epidemiologists in Japan have been performing calculations to estimate nationwide cancer incidence rates as well as 5‐year survival rates using population‐based cancer registry data. There have been remarkable changes in cancer incidence and/or mortality in cancers of the lung, liver and stomach, which were thought to be attributed to the changing impact of exposure to cigarette smoking, chronic hepatitis C virus infection and Helicobacter pylori infection, respectively. In systematic reviews providing evidence in risk/protective factors for cancer sites using case–control and cohort studies of the Japanese population, there were associations between cancer sites (esophagus, stomach, colo‐rectum, liver, pancreas, lung and breast) and various lifestyle factors. In the past 10 years, a hospital‐based case–control study at Aichi Cancer Center provided valuable evidence of gene‐environment interaction on the development of cancer [i.e., the effects of aldehyde dehydrogenase‐2 (ALDH2) polymorphism and heavy alcohol drinking on esophageal cancer, ALDH2 polymorphism and smoking on lung cancer, methylenetetrahydrofolate reductase polymorphism and heavy alcohol drinking on pancreatic cancer]. The database with stored DNA was also used and identified seven loci containing significant but low‐penetrance polymorphisms associated with the development of breast cancer. These findings together with established risk factors are likely to be useful to predict personalized breast cancer risk in East Asian women. In 2005, the Japan Multi‐Institution Collaborative Cohort (J‐MICC) study was launched to elucidate gene‐environment interactions as well as to confirm preclinical diagnostic biomarkers of cancer. J‐MICC, which has recruited 92,000 healthy individuals by the end of 2012, will follow the individuals until 2025.  相似文献

Objective

To evaluate the nature, common sites, modes of presentation of various foreign bodies (FB) in Ear, Nose and Throat (ENT).

Materials and methods

Observational retrospective study carried out at Vivekananda Institute of Medical Sciences, Ramakrishna Mission Seva Pratishthan. The study period was between Jan 2006 to Jan 2007. The information obtained from the hospital record books.

Results

Four hundred and eighty-two patients presented in the Department of Otorhinolaryngology of Vivekananda Institute of Medical Sciences, in the study period with FB in their ENT. Out of 482 pts, the commonest location of FB was to be in throat with 302 pts (62%) followed by ear with 119 pts (25%) and nose 61 pts (13%). Amongst the FB in throat the commonest was fish bone and the commonest site being tonsils. Artificial denture accounted for a significant number of 13 (4.3%). External auditory canal was the commonest site of FB lodgment in ear found in 118 patients (99.16%). Nasal FB were found in 61 patients; more common in pediatric age group (98.36%).

Conclusion

From this study we have found that FB lodgement is a very common complaint with which patients come to otolaryngologist. The commonest site of FB lodgement is in the throat. Most of the FB could be removed in emergency room (ER) with or without Local Anesthesia.  相似文献

It is well known that certain cancers have shown clustering in socioeconomic groups, but limited data are available on recent results and time trends in such clustering. We determined standardized incidence ratios (SIR) for cancer, adjusted for age, period, region, parity and age at first childbirth among men and women in 6 socioeconomic groups based on the Swedish Family-Cancer Database. Persons had to be identified with the same socioeconomic status in the census of years 1960 and 1970, or of years 1960, 1970 and 1980; the comparison group was all people according to the same censuses. Cancers were followed from years 1970 to 1998 or from 1980 to 1998. Both increased and decreased SIRs were found, and a consistent pattern emerged, although the overall SIRs for cancer did not differ much, the lowest being for farmers (0.85) and the highest for professional men (1.07) and women (1.11). At individual sites, manual workers were at risk of tobacco-, alcohol- and occupation- and human papilloma virus-related cancers and at a decreased risk at most other cancers. Manual workers and farmers showed an excess of stomach cancer; professionals had an excess of melanoma and squamous cell skin cancer. Male and female SIRs correlated highly for manual and blue-collar workers and for professionals. The overall population-attributable fraction for selected sites was 16.7% for men and 10.9% for women and it was highest, over 50%, for lung cancer in both genders.  相似文献
