Arthroscopic distal clavicle resection

The acromioclavicular joint is a potential source of pain in the shoulder. There are a variety of disorders that can affect this joint, including distal clavicle osteolysis, posttraumatic arthritis, osteoarthritis, and rheumatoid arthritis. Nonoperative treatment for this condition with nonsteroidal medication and activity modification can alleviate the pain. When conservative treatment is exhausted, surgical resection of the distal clavicle is often necessary. Arthroscopic resection of the distal clavicle preserves the acromioclavicular ligaments to prevent postoperative distal clavicle instability. The procedure is performed in either the beach chair or lateral position and requires the use of a shaver, electrocautery, and a burr for soft tissue and debridement and bone resection.

Correction of webbed-neck deformity in Turner's syndrome

Summary A case of Turner's syndrome with the typical marked webbing of the neck is presented. A posterior approach is preferred for correction of this webbed neck deformity. A butterfly shaped portion of excess skin is excised and the margins of the defect mobilised as four flaps. The flaps are sutured with a very short midline vertical component, resulting in an almost X-shaped scar. The first procedure resulted in only a partial correction of the deformity and an excess of hypertrophic scar tissue. This was treated with a repeat of the procedure but the midline wounds was repaired with mulitple small Z-plasties. The final appearance of the neck was satisfactory in the lateral profile, but there was still some excess tissue posteriorly.

Advantages of using the midline incision right retroperitoneal approach for abdominal aortic aneurysm repair

This study was conducted to compare the midline incision right retroperitoneal approach for repairing abdominal aortic aneurysms (AAA) with the transperitoneal approach. The intra- and postoperative course of 15 patients who underwent AAA repair using the transperitoneal approach between 1987 and 1991 and another 15 patients who underwent AAA repair using the retroperitoneal approach between 1991 and 1994 were evaluated. The incidence of postoperative wound complications was also assessed. There was no operative or hospital death in either group. Although a significantly longer interval was required from the incision to the aortic clamp using the extraperitoneal method, there were no statistical differences in the aortic clamping time, total operation time, or blood loss between the two groups. On the other hand, there was a statistically significant improvement in bowel function and a significant reduction in the length of postoperative hospitalization following the extraperitoneal procedure. Furthermore, no wound complications such as those associated with the left flank incision developed after the extraperitoneal procedure. Thus, we recommend the midline incision right retroperitoneal approach for AAA as it does not involve muscle division and is associated with fewer complications.     

经胼胝体穹隆间人路切除下丘脑内型错构瘤

目的探讨下丘脑内型错构瘤的手术治疗方法。方法报告4例下丘脑内型错构瘤,采用右额后开颅经胼胝体-透明隔-穹隆间入路切除下丘脑内型错构瘤。结果4例均为儿童,男女为31,均以癫痫发作为主要症状,错构瘤为大部切除或部分切除,术后低钠血症1例,轻度尿崩1例,无其他合并症。随诊半年至1.5年,无任何癫痫发作。结论经胼胝体-透明膈-穹隆间入路是下丘脑内型错构瘤的最佳手术入路,错构瘤大部切除或部分切除即可取得满意疗效。     

Laparoscopic partial nephrectomy for a renal tumor with tumor-feeding artery ligation: Left renal cell carcinoma in the posterior mid zone

The most serious problem regarding a laparoscopic partial nephrectomy is how to perform bloodless excision without causing renal ischemia in a limited working space. We report the case of a 65-year-old man with left small renal cell carcinoma in the posterior mid zone who underwent a laparoscopic partial nephrectomy through a retroperitoneal approach by carrying out the ligation of the tumor-feeding artery, but without clamping the renal pedicle. Both preoperative abdominal computed tomography (CT) and intraoperative ultrasonography revealed the tumor to be fully encapsulated. The tumor-feeding artery could be exposed by dissection from the renal hilum and, after an arterial ligation, tumor resection with a safety margin was smoothly performed with minimal bleeding. Postoperatively, CT revealed a limited defect of the renal parenchyma and excretory pyelography showed no urine leakage or urinary tract obstruction. The preoperative and postoperative creatinine levels were 0.66 and 0.69 mg/dL, respectively. As a result, a tumor-feeding artery ligation with a laparoscopic partial nephrectomy for left renal cell carcinoma in the posterior mid zone is considered to be an effective surgical modality which avoids renal ischemia and pelvic heat injury.     

Chronic Fatigue: A Survey, Outcome Study and Proposals

Background:  Sample sizes in studies of childhood chronic fatigue remain small and there is a need to integrate research findings and establish common criteria.
Method:  This is a detailed report of 20 children with medically unexplained fatigue, referred to as Chronic Fatigue Syndrome (CFS). It includes an uncontrolled outcome study of treatment based on a pragmatic cognitive-behavioural model adapted for children at Great Ormond Street Hospital for Children.
Results:  The data revealed psychological distress at 30 times the prevalence found in the normal child population, with specific high-ranking symptoms, including headache, social withdrawal and decreased appetite. Onset tended to occur at 11 years of age with some earlier problems at school age, suggesting it might be possible to identify those most at risk. Follow-up demonstrated improvement in 87% of the sample (parental report), a significant increase in school attendance and a significant decrease in symptom severity. Factors associated with good outcome were short duration of fatigue (less than a year) and behaviours that tended to combat the cycle of avoidance, such as carefully planned home-tuition.
Conclusions:  Recording a comprehensive range of symptoms and factors facilitates comparisons within and between child studies. It is proposed that symptom severity is a particularly relevant measure for Chronic Fatigue Syndrome which is characterised by persisting symptoms.
