亲属活体部分小肠移植术后早期并发症的防治

目的探讨亲属活体部分小肠移植术后早期并发症的防治。方法为3例短肠综合征患者和1例肠神经节缺失导致小肠无功能患者施行亲属活体部分小肠移植术,供、受者HLA配型均有4个以上抗原相合,供肠均取自回肠末端,长度为(150±10)cm,应用他克莫司、霉酚酸酯及甲泼尼龙预防排斥反应。术后采取抗凝、改善微循环、输注人白蛋白等措施调控患者的出、凝血功能,预防血管吻合口血栓形成和出血,给予法莫替丁或奥美拉唑预防应激性溃疡；给予头孢三代为主的抗生素、更昔洛韦以及氟康唑预防细菌、病毒及真菌感染,并注重对体表易感染部的消毒和护理；术后鼓励患者多下床活动,早期给予谷氨酰胺,尽早将营养支持治疗过渡为肠内营养,以促进移植肠功能的恢复。结果术后3d,1例患者发生肺部鲍曼不动杆菌感染,经抗生素治疗后控制。1例术后5 d移植肠系膜根部出现血肿,手术清除血肿。2例消化道分泌物及大便中发现真菌生长,给予氟康唑治疗后好转。4例在术后20 d左右均发生急性排斥反应,经加大FK506的用量,并以甲泼尼龙冲击治疗后逆转。4例患者,2例获得长期存活,至今分别存活6年8个月和3年2个月,另2例分别于术后5个月、35 d因感染死亡。结论小肠移植术后早期的并发症较多,与小肠的生理结构有关,术后早期并发症的成功防治是临床小肠移植成败的关键。     

The prevalence and expression of diabetes in a sample of optometric patients

The clinical characteristics of 100 consecutively presenting diabetic patients of an optometrist were investigated. This sample was drawn from 3798 patient first visits and represented 2.6% of the practice population sample. Diabetic retinopathy was present in 26% of the diabetic patients; this prevalence is similar to that found in diabetics examined in community based surveys. The ocular complications of diabetics observed in this study appeared to be similar to those of diabetics in the general community. The mean random blood glucose levels of the diabetics having retinopathy was not significantly different from those not having retinopathy. A first degree family history of diabetes was admitted by 46% of the diabetic subjects and was the most common associated clinical feature surveyed; a control group of non-diabetic subjects had a first degree family history of diabetes in 10% of cases. In seven patients, the diabetes was diagnosed as a result of signs detected at the optometric examination; these signs are listed. No newly diagnosed diabetic had diabetic retinopathy as a presenting sign. Ocular and systemic signs, other than diabetic retinopathy, were sought and a high prevalence of cardiovascular disease was detected in these diabetic patients. The vision of the diabetic patients was compared to that of 100 randomly selected age and sex matched controls; there was no significant difference in the visual acuity of the two groups. The implications of this finding are discussed. Guidelines for the detection and management of diabetic patients of optometrists are suggested.     

Abscess formation after transobturator sling placement: a case report

New techniques of sling placement may be associated with infectious complications. Slings through the obturator foramen and thigh can lead to a significant abscess formation within the thigh adductor muscles. A large thigh abscess associated with a transobturator sling was diagnosed and treated. The authors report the evaluation and treatment of a unique infectious complication of transobturator slings.

Intramedullary pilocytic astrocytomas — a clinical and morphological study after combined surgical and photon or neutron therapy

Ten patients suffering from intramedullary pilocytic astrocytomas (WHO-classification: astrocytoma grade I) were investigated catamnesticly. Combined surgery and radiotherapy was performed. Seven patients received neutron irradiation postoperatively. In four cases the neurological symptoms were improved after follow-up periods ranging from 33 to 89 months. The three other patients died after 6 to 21 months. The autopsy findings of a 14 year old child are presented. Our results are compared with reports in the literature. In addition, long-term problems of the spinal column are discussed. It seems that the combined surgical and neutron therapy improves the prognosis of pencil gliomas.     

Grading static versus dynamic images of contact lens complications

Background: This study was conducted to investigate grading performance when estimating the severity of static versus dynamic images of contact lens‐related ocular pathology. Methods: Thirty‐eight subjects used the Efron Grading Scales for Contact Lens Complications to grade the severity of ocular pathological changes depicted in static and dynamic (movie clip) computer‐displayed images of each of the following contact lens complications: bulbar conjunctival redness, limbal redness, papillary conjunctivitis, corneal staining, corneal infiltrates and meibomian gland dysfunction. The viewing of static and dynamic images was separated by seven weeks. Results: Grades assigned to dynamic images were 0.6 and 0.7 grading scale units higher than those assigned to static images for limbal redness and papillary conjunctivitis, respectively (p < 0.0001 for both). No difference was observed for the other four complications. There was an apparent trend for grading variability to be reduced (that is, observers grading in closer agreement) when grading dynamic versus static images. Conclusions: Absolute grades based on an assessment of signs of pathology represented in static images may, in some instances, underestimate the true severity of the condition.     

Neuroblastoma and anaesthesia

The haemodynamic problems associated with anaesthesia and neuroblastoma were reviewed in 52 children who underwent 138 operations at The Hospital for Sick Children, London, UK. At diagnosis 42 patients (81%) had elevated urinary catecholamine metabolites; nine (17%) were hypertensive, of whom eight were treated with adrenergic blockade. The incidence of intra-operative hypertension due to excess catecholamine release was 9% (13/138), and was confined to the group undergoing tumour excision (29%; 13/45). Hypertension was observed more frequently in patients who had not received chemotherapy. It was effectively controlled by labetalol. Patients symptomatic of catecholamine secretion before surgery should be managed in a similar manner for those with a phaeochromocytoma. Surgical manipulation of the tumour predisposes to paroxysmal hypertension. Careful monitoring is advised.     

Free vascularized jejunum interposition for pharyngoesophageal reconstruction after total laryngopharyngectomy

The records of 28 patients who underwent free jejunal graft reconstruction after resection for cancer involving the pharynx were analysed. Seven patients had a T₃ carcinoma, 15 patients T₄ and six patients recurrence after laryngectomy. Ten patients had received radiotherapy in the past. Post-operatively, 15 patients (54%) had complications and two patients (7%) died. No significant difference was observed in the complication rate between the group that received radiotherapy in the past and those who did not. Nineteen patients received post-operative radiotherapy. Nine patients had no radiotherapy on the basis of complete resection or because of serious complications. For the whole group the 2-year recurrence free period and survival were 42% and 51% respectively. The postoperative radiotherapy group had a significantly better survival (73%) and recurrence free period (63%) than the group without post-operative radiotherapy (0%). Thus, post-operative radiotherapy seems indicated irrespective of resection margins.     

A review of 2975 consecutive operations by one surgeon in an accredited outpatient plastic surgicentre: A Canadian experience

The present paper constitutes a retrospective review of 2975 consecutive operations performed by the author, one of the three owners of the Saskatoon Plastic Surgicentre. The unit opened in 1987; therefore, the study spans 17 years. Patients are not kept overnight, and the Surgicentre is approved and equipped as a level C facility for general anesthesia. Only patients who score 1 or 2 according to the American Association of Anesthesiologists are treated. Only certified anesthesiologists are used. Of the patients with postoperative complications, only two required transfer to a hospital. One developed a pneumothorax, which was treated on arrival at the intensive care unit with no sequelae. The other collapsed following facelift surgery. She was transferred to University of Saskatchewan hospital and died later that evening with a massive pulmonary embolus. In a properly established outpatient centre, a large number of patients can be safely treated with very few complications. However, despite placing patient safety as the first consideration and adhering strictly to the highest standards, death can occur.     

Results of surgical treatment in patients with arachnoid cysts

Summary A retrospective study of 35 patients operated upon for arachnoid cysts during the last 10 years was carried out. In 19 patients treated by craniotomy, membrane resection and drainage into the basal cisterns, clinical improvement could be noted in 13 cases. Correspondingly on the CT-controls the cysts were found to have disappeared in two cases and were reduced in size in seven patients.In 11 patients, however, who were initially treated by a shunting procedure, seven patients became free of symptoms. Postoperative CT-controls showed in three cases a significant reduction of the size of the cyst, which remained unchanged in two other cases.In five patients with the combination of a nonspace-occupying arachnoid cyst and subdural effusions, drainage of the latter only was sufficient to relieve the clinical symptoms.The prominent Endings were the high complication rate of the primary or secondary shunting procedures (48%), as well as the close correlation between the clinical outcome and the postoperative CT-controls.
