A Reproducible Technique for Arthroscopic Acromioclavicular Joint Excision

Arthroscopic acromioclavicular joint excision is a commonly performed but technically demanding procedure. Incomplete excision can leave residual symptoms. We present a simple, reproducible technique ensuring satisfactory excision of the joint.

[目的]探讨供血动脉栓塞对骨盆肿瘤手术疗效的影响。[方法]本组16例，脊索瘤7例，骨巨细胞瘤3例，骨转移瘤3例，骨肉瘤2例，神经纤维瘤1例。术前1d行肿瘤血管造影并用明胶海绵进行供血动脉栓塞。与对照组（结扎双侧髂内动脉骨盆肿瘤切除术）比较，观察其对术中出血量、手术时间、住院时间、术后下床时间、伤口愈合时间及术后各种功能恢复的影响。[结果]骨盆肿瘤切除术前肿瘤供血动脉栓塞与结扎双侧髂内动脉比较，除术中出血量外（P〉0．05），手术、住院、术后下床及伤口愈合时间在统计学上均有非常显著性差异（P〈0．001），而且结扎双侧髂内动脉可能对患者的性功能、排便功能等存在着不良的影响。[结论]肿瘤供血动脉栓塞骨盆肿瘤切除术可大大缩短手术、住院、术后下床、伤口愈合时间，且能更好地保护盆腔内外各组织器官的血运，从而避免其功能的损害。     

Standardized quick en bloc technique for procurement of cadaveric liver grafts for pediatric liver transplantation

This paper describes a quick procedure for cadaveric liver graft retrieval during multiple organ harvesting. The technique is based on minimal preliminary dissection, absence of in situ direct portal perfusion, and en bloc removal of the liver and pancreas, with an aortic patch encompassing the coeliac trunk and superior mesenteric artery. The results of 110 pediatric liver transplantations with 109 organs harvested using this technique are reported. There were no graft harvesting injuries. The liver graft primary nonfunction rate was 4.5% (5/110). The 3-month retransplantation rate was 10%. The actual patient survival rates were 93% at 3 months and 90% at 1 year; actual graft survival rates were 85.5% and 78%, respectively. The technique described was at least as safe as conventional procedures. A major advantage of the procedure is its flexibility, which allows for the easily combined procurement of other organs (whole pancreas and intestine).     

原发性腹膜后脂肪肉瘤20例报告

自１９６５年５月至１９９１年７月共收治原发性腹膜后脂肪肉瘤２０例，均经手术及病理证实。２０例中完全切除者１５例，部分切除者４例，活检１例。肿瘤切除合并肾，肠襻等邻近器官切除者达１２例。全组的５年，１０年生存率分别是５７．１％和２０．０％，完全切除组的５年１０年生存率分别是６３．６％和２８．６％。２０例病人共进行了４８次切除手术。首次手术死亡２例。着重讨论了本病的诊断、治疗和突出的临床特点。     

Angiolymphoid hyperplasia with eosinophilia: report of a large-sized scalp lesion

In this report, a case is presented with large recurrent, benign, vascular and proliferative lesion on the scalp. Complete surgical excision of the tumor mass and split thickness skin grafting of the defect had favorable results with no recurrences after 24-month follow-up.     

Ectopic cervical salivary glands

Summary Ectopic salivary glands in the neck are very unusual lesions. Generally they are localized to the oropharyngeal region, near the mandible and para-parotid lymph nodes. They occur occasionally on the anterior border of the sternocleidomastoid muscle in the soft tissues of the neck. We wish to report on a singular association of ectopic salivary glands with partial hearing loss, preauricular fistula, palatoschisis, anal fistula, and an arteria lusoria. Morphological, histological and embryological aspects are discussed.     

Recovery and Utilization of Deceased Donor Kidneys from Small Pediatric Donors

The optimal use of kidneys from small pediatric deceased donors remains undetermined. Using data from the Scientific Registry of Transplant Recipients, 2886 small (< 21 kg) pediatric donors between 1993 and 2002 were identified. Donor factors predictive of kidney recovery and transplantation (1343 en bloc; 1600 single) were identified by logistic regression. Multivariable Cox regression was used to assess the risk of graft loss. The rate of kidney recovery from small pediatric donors was significantly higher with increasing age, weight and height. The odds of transplant of recovered small donor kidneys were significantly higher with increasing age, weight, height and en bloc recovery (adjusted odds ratio = 65.8 vs. single; p < 0.0001), and significantly lower with increasing creatinine. Compared to en bloc, solitary transplants had a 78% higher risk of graft loss (p < 0.0001). En bloc transplants had a similar graft survival to ideal donors (p = 0.45) while solitary transplants had an increased risk of graft loss (p < 0.0001). En bloc recovery of kidneys from small pediatric donors may result in the highest probability of transplantation. Although limited by the retrospective nature of the study, kidneys transplanted en bloc had a similar graft survival to ideal donors but may not maximize the number of successfully transplanted recipients.     

The number of proliferating cell nuclear antigen positive cells in endometriotic lesions differs from that in the endometrium

Immunohistochemical expression of proliferating cell nuclear antigen (PCNA) was studied in the endometrium and in endometriotic lesions during the menstrual cycle and in post-menopausal patients. During the menstrual cycle, in the basal layer of the endometrium, an increase in the number of positive indices (PI) of PCNA was observed in epithelial cells from the menstrual phase. It reached a maximum in the proliferative phase and decreased in the secretory phase. However, no change was observed in the stromal cells of the basal layer. In the functional layer of the endometrium, the PI of the epithelial cells showed a high peak in the late proliferative phase, decreased sharply in the secretory phase and remained unchanged thereafter. The PI of the stromal cells in the functional layer showed two peaks, one in the late proliferative and the other in the mid and late secretory phase. In the endometriotic lesions, except for the proliferative phase, the number of PI was significantly higher than that of the corresponding endometrium and no significant changes were observed during the menstrual cycle. In post-menopausal endometriotic lesions, the number of PI was also higher than that of the corresponding endometrium. Thus the numbers of PI differed between the endometrium and endometriotic lesions in the same patients. These results imply that the endometriotic lesions are constantly more proliferative than the endometrium irrespective of the hormonal milieu during both the menstrual cycle and in a post-menopausal environment.

A comparison of the effects on follicular development between clomiphene citrate, its two separate isomers and spontaneous cycles

An investigation of the effects on follicular development of clomiphene citrate and its two isomers En clomiphene and Zu clomiphene given separately was carried out on 19 normally cycling women being treated with donor insemination. All women received clomiphene citrate in the first cycle and, following a washout control cycle, were treated with either En clomiphene or Zu clomiphene alone. The number of follicles present, follicular phase oestrogen secretion and luteal phase pregnanediol excretion were not significantly different when Zu clomiphene cycles were compared with control cycles, but were significantly increased in En clomiphene and clomiphene citrate cycles. It is concluded that the En isomer, which has largely antioestrogenic properties, is the isomer active in inducing follicular development. The oestrogenic properties of Zu isomer did not appear to protect it from the possibly detrimental effects on sperm-cervical mucus interaction observed in both isomers and in the combined preparation.
