OBJECTIVES: To identify the incidence of level IIb lymph nodes metastasis in elective supraomohyoid neck dissection (SOHND) as a treatment for patients with squamous cell carcinoma (SCC) of the oral cavity. STUDY DESIGN: Prospective analysis of a case series. METHODS: Forty-eight patients with SCC of the oral cavity and with no palpable lymph nodes at the neck who underwent an elective SOHND were prospectively studied. The incidence of micrometastasis to level IIb lymph nodes after performing elective SOHND was evaluated by pathologic examination and molecular analysis. RESULTS: Of the 48 patients, 15 (31%) by pathologic analysis and 22 (46%) by molecular analysis had lymph nodes positive for metastatic SCC. By molecular analysis, 5 (10%) of the 48 patients had involvement of level IIb lymph nodes. All patients with metastasis to level IIb lymph nodes have their primary lesions in the tongue and constituted 22% of patients with tongue lesions. There was no instance of isolated metastasis to level IIb lymph nodes without involvement of other nodes in the SOHND specimens. CONCLUSIONS: In this study, level IIb lymph node metastasis was only found in association with tongue carcinoma. Although this region may be preserved in elective SOHND in patients with SCC of the oral cavity, it should be included whenever the tongue is the primary site.  相似文献

Smartphone technology is nascent compared to other technologies; however, it has shown an unprecedented uptake amongst lay consumers and professionals. This article presents the history, components, and key features of smartphones, as well as their related concepts and how they work, and it also delineates the process of smartphone applications (apps) development and publishing in the app stores. It also describes and discusses smartphone technology utilisation for health consumers, healthcare professionals, and health researchers, as well as the regulations of health-related apps.  相似文献

Purpose

To evaluate the short-term results of sub-tenon’s injection of bevacizumab in patients with clinically significant macular edema (CSME).

Methods

In this prospective non-comparative interventional case series, sub-tenon’s injection of 2.5 mg/0.1 ml bevacizumab was performed for eyes with CSME. Macular thickness and best corrected visual acuity measurements were performed before and one month after injections.

Results

Nineteen eyes of twelve patients with a mean age of 59.8 ± 5.7 years were evaluated. Thirteen eyes (68.4%) had center-involving macular edema. No significant difference was observed between pre- and post-injection central subfield retinal thickness measurements (P = 0.3). Central subfield thickness measurements improved or remained unchanged in 13 eyes (68.4%). Baseline BCVA of 0.48 ± 0.35 LogMAR improved to 0.36 ± 0.26 LogMAR after injection (P = 0.01). Improvement of >2 lines in BCVA was found in 5 eyes (26.3%), and no eye lost >2 lines of BCVA. No complication associated with sub-tenon’s injection was observed.

Conclusion

Sub-tenon’s injection of bevacizumab resulted in significant short-term visual improvement in eyes with CSME. Retinal thickness changes were not significant.  相似文献

OBJECTIVE: This study compares telephone consultations with the results of clinical examinations to assess the value and accuracy of telephone consultations for the future planning in a breast cancer clinic in Tehran, Iran. METHODS: In 2500 telephone calls, 800 Symptomatic patients were identified and asked to visit the center for the further investigations by the specialists. The agreement between two observers data were compared by the kappa statistic. RESULTS: Totally 174 patients complied with the recommendation and included in the study. The most common chief complaints of visitors were: breast mass (42%) and breast pain (35%). Kappa statistic showed a very good agreement (K=0.62, P<0.001) between consultants' diagnosis and the specialists findings. This agreement for breast cancer diagnosis, although lower, was also good (K=0.55, P<0.001). CONCLUSION: The study findings indicate that consultants may diagnose and manage some common conditions via telephone, usually following the established protocols. More studies are needed to determine the economic and logistic advantages of telephone consultations. PRACTICE IMPLICATIONS: By assessment of strength and weakness of this service, it is possible to develop an easy to use information system for women who need breast care.  相似文献
