A role for lasers in the treatment of pigmented skin grafts

The development of aberrant pigmentation represents an unwelcome complication to an otherwise successful split skin graft resulting in a loss of colour match and, so it follows, of cosmesis. We present two cases where lasers have been successful in the treatment of this problem.     

二尖瓣球囊扩张术并发心脏压塞1例的抢救与护理

目的:报告二尖瓣球囊扩张术(PBMV术)并发心脏压塞的抢救与护理.方法:主要从患者的术前准备、术中抢救与配合、术后护理介绍.结果:准备充分,抢救及时,护理得当,患者病情稳定后转心脏外科手术治疗.结论:二尖瓣球囊扩张风险大,心脏压塞是最危险、最常见的并发症之一,故加强术前准备,密切术中配合,及时抢救尤为重要.     

The pancreas in acute graft versus host disease in man

Twenty-six bone marrow transplant recipients, 14 of whom had evidence of acute graft versus host disease at autopsy, were studied. The pancreas in four of these patients exhibited changes thought to be due to acute graft versus host disease. Pathognomonic findings were in exocrine ducts which showed marked epithelial cellular atypia associated with a mild lymphocytic infiltrate. This was accompanied by ulceration and intraluminal haemorrhage in severe cases. In three of these four cases ductal epithelium showed marked hyperexpression of class I and class II major histocompatibility complex molecules. By contrast islets were not inflamed, showed no evidence of endocrine cell damage and no abnormalities of major histocompatibility complex expression were seen.     

腹式全子宫切除术不同术式对排便功能影响的探讨

目的:探讨筋膜内和筋膜外全子宫切除术对女性排便功能的影响。方法:76例全子宫切除患者分为筋膜外全切除组(A组)56例,筋膜内全子宫切除组(B组)20例,对两组术后病人的排便次数,难易程度的变化进行分析。结果:76例全子宫切除病人42.1％出现不同程度排便困难,A组52.62%,B组为10%,两组具有显著性差异(P<0.05)。结论:全子宫切除术后可影响女性排便功能,筋膜内全子宫切除术对排便功能影响小,是一种较好手术方式。     

心脏移植术后急性排异反应的监测

目的 总结原位心脏移植术后急性排异反应的监测。方法 2000－01／2002－04施行11例原位心脏移植手术，结合临床表现、心电图、超声心动图、化验检查及心内膜活栓等检查，对心脏移植术后急性排异反应的监测进行分析。结果 采用临床症状＋心电图＋超声心电图＋心肌血清学检测综合判断有6次急性排异反应，行心内膜活检证实Ⅰb级2次，Ⅲa级3次；术后常规行心内膜活检21次，仅发现急性排异反应Ⅰa或Ⅰb级5次。结论 急性排异反应是关系到心脏移植术后患者康复及愈后的重要因素，因此要及时、有效地进行监测；心内膜心肌活检是诊断急性排异反应敏感可靠的方法，但为有创性检查，有一定的并发症风险，其他多项无创性检查可作辅助指标，因此急性排异反应监测应把无创性检查与心内膜心肌活检有机地结合起来。     

Rotational acetabular osteotomy for acetabular dysplasia of the hip with a giant acetabular bone cyst: a case report

In acetabular dysplasia of the hip joint accompanied by a giant acetabular bone cyst, rotational acetabular osteotomy may cause serious complications, such as bone necrosis after surgery or fracture of the fragile acetabulum during the operation. In a patient with this condition, we performed a two-stage operation: first, autogenous bone grafting supplemented with hydroxyapatite filling, then rotational acetabular osteotomy (after new bone formation had been assured). Radiographs and CT scans showed favorable fusion of the grafted bone. Some 18 months after the second operation, arthrograms showed no inflow of contrast medium from the articular cavity into the bone cyst region, although this had been observed before treatment. Thus, an effective remodeling of bony congruency was indicated in the mobile acetabulum 5 years after the second operation. This two-stage operation appears to be useful for correcting acetabular dysplasia accompanied by a giant bone cyst and to carry a reduced risk of serious complications, such as deterioration of the articular surface of the acetabulum or necrosis of the translocated acetabulum.     

Laparoscopic (vs. Open) Live Donor Nephrectomy: A UNOS Database Analysis of Early Graft Function and Survival

The impact of laparoscopic (lap) live donor nephrectomy on early graft function and survival remains controversial. We compared 2734 kidney transplants (tx) from lap donors and 2576 tx from open donors reported to the U.S. United Network for Organ Sharing from 11/1999 to 12/2000. Early function quality (>40 mL urine and/or serum creatinine [creat] decline >25% during the first 24 h post-tx) and delayed function incidence were similar for both groups. Significantly more lap (vs. open) txs, however, had discharge creats greater than 1.4 mg/dL (49.2% vs. 44.9%, p = 0.002) and 2.0 mg/dL (21.8% vs. 19.5%, p = 0.04). But all later creats, early and late rejection, as well as graft survival at 1 year (94.4%, lap tx vs. 94.1%, open tx) were similar for lap and open recipients. Our data suggests that lap nephrectomy is associated with slower early graft function. Rejection rates and short-term graft survival, however, were similar for lap and open graft recipients. Further prospective studies with longer follow up are necessary to assess the potential impact of the laparoscopic procurement mode on early graft function and long-term outcome.     

肝外胆管癌的诊治分析

目的：探讨肝外胆管癌的诊断和治疗的体会。方法：回顾性总结手术治疗的32例肝外胆管癌的临床资料、手术方式、手术并发症及生存率，并复习相关文献资料。结果：本组病例获根冶性切除14例，姑息切除2例，胆道引流术16例；手术并发症10例(31.3％)，手术死亡1例(3．1％)。其中22例获定期随访，存活一年以上的有12例(12／22)，至今存活8例。结论:早期诊断、正确的评估、合理的术式选择能提高疗效。降低手术并发症及死亡率。
