Tumor location and drug targeting using a monoclonal antibody (anti-SSEA-1) and antigen-binding fragments

Both murine and heterotransplanted human nonseminomatous germ-cell tumors have been successfully located by external scintigraphy using radioiodinated anti-SSEA-1, a monoclonal IgM, and its pepsin-derived antigen-binding fragment, F(ab')2 mu. Antibody localization in the tumor is mainly due to antigenic specificity, rather than to nonspecific trapping, and depends strongly on the amount of time after injection. The antibody has been used for drug targeting in vitro and in vivo.     

Pain location and associated symptoms in post-lumbar puncture headache

In this prospective study of 239 patients, 88 (37%) suffered from post-lumbar puncture headache (PPH). The pain was located within the region innervated by the trigeminal nerve in 49% of the drawings, within the occipital and/or suboccipital region in 11%, and within the combined trigeminal/occipital region in 39%. The headache was unilateral at least once in 34% of the patients. Changes in pain location from one region to the other and/or between bilateral and unilateral headache were observed in 54% of the patients throughout the PPH period. Associated symptoms were experienced by 85%, nausea (73%) and dizziness (60%) being the most frequently reported. In the upright position, nausea, dizziness, and tinnitus tended to be present during a fairly large part of the PPH period (57–63% of the days), vomiting occurring only occasionally (28%). The intensity of associated symptoms was positively correlated to PPH severity. Pain in the combined trigeminal/occipital region was most severe and related to more associated symptoms than pain in other regions, and unilateral pain was milder than bilateral pain. Pain in the occipital and/or suboccipital region was mildest. The severity of nausea decreased significantly on the last 2 days of the PPH period, and the intensity of dizziness decreased when PPH was about to subside. Tinnitus is probably due to a cochlear dysfunction, and presents special characteristics. Its incidence was not clearly related to PPH severity and it increased with increasing duration of PPH; its intensity did not decline when PPM was about to wane.     

肿胀法行体外、内超声及单纯负压吸脂减肥术的比较

目的 比较在肿胀麻醉下行体外、体内超声及单纯负压吸脂术的效果。方法 对应用上述3种吸脂法的276例受术者的吸脂量、吸脂时间、术后并发症、皮肤皱折、皮肤弹性恢复程度及术中术者体力消耗等多项指标进行对比。结果 体外超声可以最快速使脂肪乳化，便于吸脂，且术后并发症出现最少，体内超声次之，单纯法最多。结论 体外超声吸脂要是一种有效、安全的局部减肥方法。

局限型腺炎在影像学上的表现与肿有为相似。本文予其声像图较详细的分析，以探讨良恶性病变的鉴别诊断。共收集了我院诊治的１０经病理和细胞学证实的局限型胰腺炎。从５个方面，即病灶、病灶以外的胰腺，胰管，胆总管，邻因管管，回顾性分析其声像图表现。     

A CASE OF TESTICULAR TERATOMA LOCATED IN THE OPPOSITE SIDE OF THE UPPER ABDOMINAL WALL

We report a case of a testicular teratoma located in the opposite side of the upper abdominal wall. A 2-year-old boy presented with a non-palpable right testis and underwent right inguinal exploration for right cryptorchidism. During surgery, the tumor was found in the opposite side of the upper abdominal wall across the midline. Histological investigation of the tumor revealed a mature teratoma occurring in the intra-abdominal testis. No such case has been previously reported.     

Intraocular lenses. Histopathologic characteristics of a large series of autopsy eyes

Histopathologic changes in cornea, anterior chamber angle, iris and ciliary body of 119 autopsy eyes containing intraocular lenses are described and illustrated. Results are categorized according to type of intraocular lens (anterior chamber, iris fixation, iridocapsular, and posterior chamber), and methods of fixation are specified. Changes are categorized as: erosion, atrophy, proliferation of tissues and inflammatory reactions. In some instances, these histopathologic changes may provide a basis for understanding certain clinically evident complications.     

Miccoli法甲状腺切除术

目的探讨在腹腔镜辅助下用超声刀行甲状腺切除术的可行性及优越性.方法对14例病人在腹腔镜下使用超声刀自颈部小切口行部分或次全甲状腺切除术.结果14例均完成手术.无一例中转手术.手术时间30～70min,平均45 min.术后病理报告均为结节性甲状腺肿.全组病例术后恢复良好,无切口感染及积液,颈部切口仅为2.5cm左右.14例随访3～17个月,均对瘢痕效果满意.结论Miccolli法甲状腺切除术具有操作简单,美容效果明显等优点.     

卵巢巧克力囊肿的超声显像特征

目的：探讨卵巢巧克力囊肿的超声表现特征。方法：分析１１０例卵巢巧克力囊肿的超声显像特点，将其分为４种类型：（１）单纯囊肿型；（２）均匀点状回声型；（３）混合回声型；９４）实体回声型。一手术病理相对照，并与盆腔其他２包块相鉴别。结果：超声诊断总符合率为６５．４％，其中均匀点状回声型为９３．３％，与其余３型对比差异有高度显著性。结论：超声诊断卵巢巧和囊肿有一定价值，均匀点状型为卵巢巧克力囊肿的超声特征
