Management of cancer of the base of tongue

The management of base of tongue cancer has evolved steadily over time. Organ preservation with primary radiation therapy has produced excellent oncologic and functional outcomes. Concomitant chemotherapy has become important in patients with locoregionally advanced disease. Planned neck dissection after organ preservation therapy continues to be an integral step for regional control. This article reports the results of a literature review of base of tongue cancer emphasizing a multidisciplinary approach to obtain optimal results in terms of cure and quality of life.     

耳廓开放性外伤的治疗方法探析

目的 探讨耳廓开放性外伤的治疗方法。方法 23耳耳廓开放性外伤经彻底清创，肝素生理盐水冲洗伤口后，对位缝合。术后用抗生素抗感染、丹参扩张血管、罂粟碱改善微循环。结果 23耳中2耳失访，18耳完全成活，1耳部分成活，2耳完全坏死。结论 耳廓撕裂伤、断伤、带有皮蒂的耳廓离断伤，由于断端双侧血管丰富，经对位缝合后容易成活。但耳廓完全离断伤由于缺乏血供，经对位缝合后不易成活，可采用去皮血管植入包埋法，带肌蒂皮瓣移植法或尝试显微外科技术施行血管吻合，以提高耳廓完全离断伤的成活率。     

Methods of analysis of large numbers of audiograms

The analysis of large numbers of audiograms raises the question if and how we can reduce the amount of data without discarding essential information. The present paper compares two ways of data reduction: principal-component analysis and curve fitting. The methods are tested on the audiograms of a large family suffering from a dominant hereditary, progressive hearing loss, beginning in the high frequencies. It is shown that principal-component analysis rejects information on the shape of the audiogram, as do all methods generally referred to as factor analysis. The information concerned is essential for our understanding of the patient's ability to discriminate speech. Curve-fitting procedures are shown to be effective in data reduction.
