Mohs Micrographic Surgery (MMS) is widely employed in the treatment of non-melanoma skin cancer and is a preferred treatment for many cutaneous malignancies, particularly in high risk locations and tumors [1,2]. It has also been used in the narrow excision of malignant melanoma with local control rates equivalent to standard margins [3]. It has gained acceptance in the treatment of noninvasive melanoma where standard 0.5 cm margins may be inadequate for local control [4]. The frozen section processing used in MMS has been assumed by some to be inadequate in assessing melanocyte populations or residual melanoma within excision margins. This difficulty has likely led to a majority of surgeons with fellowship training to process margins with slow, permanent hematoxylin and eosin sections (“slowmohs”) or to simply resort to standard 0.5, 1.0, or 2.0 cm margins with traditional excision and outside pathology confirmation of clear margins. A recent survey of practicing fellowship-trained Mohs surgeons revealed roughly one-third (35.9%) of Mohs surgeons felt comfortable interpreting MART-1 immunostains, and far fewer were actually performing immunostains in their labs [5]. Some Mohs surgeons currently refer melanoma to a colleague experienced in processing and reading melanoma with available rapid immunostaining. The development of rapid immunohistochemistry, which can be implemented into a traditional frozen section laboratory, has greatly improved the ease of interpreting margins in the excision of melanoma. Although the process is considerably more complicated than staining with H&e or Toluidine Blue (T-Blue), it easily falls within the skill-set and equipment of most busy frozen section laboratories. The additional cost of biologic reagents may be fully recovered by proper billing of immunohistochemical laboratory work and interpretation of slides.

1988～1992年经过5年的研究确定放牧日和放牧频率对北美长叶沙茅[Calamovilfalongifolia(Hook.)Scribn.]和砂生须芒草(Andropogon hallii Hack.)总有机物质储藏的影响。处理由6月,7月,8月,10月,6月和7月,6月和8月,7月和8月或者6月,7月和8月的月中放牧周期组成。各处理间季节载畜量相同且均等地分成多个放牧周期。用一岁牛在同一草地上进行了连续4年的放牧试验。放牧周期为4～7d。早春黄化生长的分蘖枝平均重量常用于估计5年总有机物质储藏。每种牧草在10月份休眠期放牧和休闲,4年间无显著差异。在6月份或7月份分区进行放牧时,尽管每个试验放牧周期长短不同,长叶沙茅总有机物质储藏均降低。在6月或者8月份放牧一次能维持砂生须芒草的储藏。在6～8月份草地轮牧2次或多次至少维持或者增加每种牧草的总有机物质储藏。6月初混合放牧周期能减少大约38％的长叶沙茅有机物储藏和30％的砂生须芒草的储藏。在载畜量相同情况下,6月份放牧可推迟放牧周期60d以上,避免了两种牧草的总有机物质储藏的减少。放牧周期推迟到8月中旬或者下旬将会获得维持长叶沙茅和砂生须芒草储藏的高水平。

本研究在美国蒙塔那州禾草草原上进行了取样时间和样方间移动时间的统计、比较了不同样方大小和形状所费时间的差异、用草地牧草产量和5种植物分种产量的变异性进行检验,认为在当地植被分布格局下,长方形样方对缩小分布不均的植物种的现存量变异性是有效的,而对总产量和低矮禾草则无影响。样方大小与形状的最佳组合中各个组合所用于刈割和行走费的时间是相同的。

为了定量描述放牧日期和频率对草原砂芦(Calamovilfa logifolia)和砂生须芒草(An-dropogon hallii)总有机物贮藏量的影响,从1988年起至1992年止进行了5年试验研究。处理包括8种月中放牧期。各处理季节放牧率相等,并均分于各个放牧期内。在连续4年期间,各放牧处理均在相同草场饲喂一龄牛,且放牧时间均为4～7d。到第5年黄化初春生长产生分蘖技的平均重量可用来估测其有机质总贮备量。试验结果表明,当放牧率与本研究相同时,为避免6月份放牧导致这两种草贮备物的下降,就须使其放牧期延迟长达60d。另外,为使这两种草贮备物的量同时达到高水平,就须延迟放牧至8月中旬或更晚。

Paget disease of the vulva is a rare lesion that accounts for eoplasms. A 12% prevalence of invasive Paget carcinoma and a 4% prevalence of associated adenocarcinomas are described. Furthermore, a high recurrence rate of 30% after surgical therapy is observed. This study aims to search for therapeutic strategies for recurrent Paget disease, which are less mutilating and less aggressive than reexcision, x ray therapy, or chemotherapy. Trastuzu mab (Herceptin.) is a recombinant monoclonal antibody against HeR- 2/neu, approved by the U.S. FDA for the treatment of patients with HeR- 2/neu- positive metastatic breast carcinomas. The results of recent studies indicate that HeR- 2/neu oncoprotein may play a role in the pathogenesis of extramammary Paget disease. Using HercepTest., we analyzed HeR- 2/neu overexpression in seven noninvasive Paget lesions, two invasive lesions, and one Paget disease of the vulva with underlying adenocarcinoma. In addition, we investigated five mammary Paget diseases. Overexpression of HeR- 2/neu oncoprotein labeling exclusively the membranes of Paget cells was demonstrated in 8 out of 10 cases. One noninvasive and one with underlying adenocarcinoma stained negatively. Overexpression of HeR- 2/neu was demonstrated in all five cases of mammary Paget disease. Using HercepTest. as a standardized detection system, overexpression of HeR- 2/neu can be demonstrated in a majority of both noninvasive and invasive Paget disease of the vulva. The use of Trastuzumab should be considered for the treatment of patients with recurrent Paget disease of the vulva with overexpression of HeR- 2/neu.
