The Mitek mini anchor in the treatment of the gamekeeper's thumb

The fixation of a distally ruptured ulnar collateral ligament of the MP 1 (Metacarpophalangeal) joint without a portion of ligament which can be sutured or a small bony fragment can be accomplished with a variety of methods, most of which require drillholes through borth cortices and a counter incision as well as the removal of the material at a second stage [1, 11, 13, 15]. The Mitek bone mini anchor (Ethicon-Mitek®) proved to be a reliable and quick alternative [10, 12, 16, 18, 19]. It was successfully used in eleven patients with excellent stability of the reconstructed joint.

Intraoperative radiotherapy in the multidisciplinary treatment of bone sarcomas in children and adolescents

From September 1984 to December 1989, 38 patients of pediatric age with localized bone sarcomas received intraoperative radiotherapy (IORT) as part of a multidisci plinary treatment program. The age ranged from 6 to 21 years. The tumor histologies were 22 osteosarcomas and 16 Ewing's sarcomas. Thirty-four had initial primary disease (90%) and 4 were treated for local recurrence (10%). IORT was used on 32 untreated patients and in 6 previously treated with external beam radiotherapy (EBR). The IORT field included the surgically exposed tumor bed area. Single radiation doses ranging from 10 to 20 Gy were delivered, using 6–20 MeV electron beams. The median follow-up time for the entire group is 25 months (2–65+ months). The projected 5-year disease-free and overall survival rates are 65% and 69%, respectively. One patient developed a local recurrence in each histological group: one chondroblastic osteosarcoma and one cervical Ewing's sarcoma. Six patients died from metastatic progression: 3 initially recurrent tumors and three primary disease cases. Severe neuropathy and soft tissue necrosis were seen in some patients as IORT related complications. IORT is a feasible technique to be integrated in multidisciplinary programs that may promote local control in pediatric and adolescent patients with bone sarcomas. Peripheral nerves are dose-limiting tissue structures for IORT.     

瘤体骨切除灭活再植治疗四肢长骨巨细胞瘤

体内刮除及灭活植骨治疗骨巨细胞瘤（ＧＣＴ）的复发率高。我科从１９８６年６月～１９９６年２月治疗四肢长骨ＧＣＴ２４例。随访１１个月～８年４个月。其中７例采用局部切刮体内灭活植骨和（或）骨水泥充填治疗。结果１例感染，６例复发，１例恶变后死于肺转移。作者自１９９１年１月采用瘤体骨切除，离体灭活再植，与骨残端体内灭活相结合，骨缺损采用自家腓、髂骨移植，Ｌ－梯形加压钢板（Ｌ－ＴＣＰ）或梯形加压钢板（ＴＣＰ）固定治疗１７例，其中１２例保留关节，５例做膝关节融合。本组无菌创口感染１例，１例复发。在保留关节的１２例中９例关节功能恢复优良，１例尚可，２例差。充分说明瘤段骨切除体外灭活再植术疗效确实，复发率低。保留关节术式适于关节破坏较轻（＜＝１／２）者，结合关节残端体内灭活和有效的骨结构重建，有利于恢复关节功能。如关节面累及＞１／２，宜做骨关节端切除，灭活再植，下肢宜做关节融合或人工关节置换术。     

Cancellous Bone Structure in the Growing and Aging Lumbar Spine in a Historic Nubian Population

There is abundant data on cancellous bone in the aging human spine, but little relating to the growing vertebral cancellous bone in childhood and adolescence. The purpose of this study was to map vertebral cancellous bone in a growth and age series of historic skeletal samples and to make comparisons with data published on recent material. Lumbar vertebral bodies were collected from 65 skeletons (0–60 years) from a medieval Nubian population. Ethnohistoric information was collected to interpret conditions that might have influenced bone structure and metabolism. The cancellous bone was studied three dimensionally, using stereophotography and scanning electron microscopy and morphometrically by performing a semiautomatic structural analysis on digitized backscattered electron images of polymethacrylate-embedded material. The cancellous bone structure in the children consisted mainly of a densely packed, uniform network of small rodlike trabeculae. The greatest bone volume fraction with small, more platelike trabeculae was observed during adolescence. In young adults, larger platelike trabeculae were present in the central zone and smaller trabeculae in the superior and inferior zones, as described for modern skeletal material. Structural changes associated with aging were observed much sooner than in modern man. By the estimated age of approximately 50–60 years, the predominant architectural elements were slender rarified rods in both sexes. The ethnohistorical data suggest that this was essentially a black African population of physically active peasants, not likely to suffer Vitamin D insufficiency or deficient calcium intake. Thus an earlier onset of the biological age changes in cancellous bone found in modern populations was probably prevalent. Received: 1 March 1996 / Accepted: 31 December 1996     

Widenings of the myelin lamellae in a typical Guillain–Barré syndrome

The so-called “widenings of the myelin lamellae” are thought to be specific ultrastructural features of peripheral nerve myelin in patients with peripheral neuropathy associated with a monoclonal dysglobulinemia of IgM type and antiglycolipid activity. We report here a case of Guillain–Barré syndrome with no evidence of serum monoclonal dysglobulinemia, presenting the typical widenings of the myelin lamellae in small-diameter myelinated fibers from a sural nerve biopsy. In view of the positive reaction with anti-C3d complement on direct immunofluorescence, an immunological mechanism may be involved in the widenings of the myelin lamellae. © 1994 John Wiley & Sons, Inc.     

16例胸膜间皮瘤临床分析

１６例胸膜间皮瘤，其中１例有石棉接触史，占６．１７％；＞４０岁者占８１．５％。主要临床表现为胸痛、气短、咳嗽、低热和胸腔积液，临床上易误诊为结核性胸膜炎、肺癌胸膜转移等。胸部ｘ线检查及胸部ＣＴ对该病的诊断有帮助，大都有特征性表现。确诊靠针刺胸膜活检及开胸活检。胸膜间皮瘤的治疗主要采用手术、放疗和化疗，对于局限型治疗首选手术切除。肿瘤的良、恶性、疾病的分期及治疗与预后有一定关系。     

Kimura's disease associated with minimal change nephrotic syndrome: A case report

Kimura's disease is a rare disorder that involves regional lymph nodes and the major salivary glands, which become infiltrated by eosinophils and lymphocytes. Renal lesions associated with Kimura's disease are rare. We describe the case of a 60-year-old Japanese woman who first noted a nodular mass in a salivary gland. As the nodule grew, nephrotic syndrome and heart failure developed. A biopsy of the nodule revealed Kimura's disease, and surgical excision was performed. After the operation, the heart failure and nephrotic syndrome, which were diagnosed as minimal change disease on renal biopsy, improved rapidly without steroid therapy. Four months later, the nephrotic syndrome recurred without recurrence of Kimura's disease. The patient showed marked improvement during prednisolone therapy (40 mg/d) and was in complete remission 4 weeks after the initiation of steroid therapy. This case shows that surgical excision and prednisolone therapy are useful for nephrotic syndrome associated with Kimura's disease.     

Graft versus graft and graft versus host reactions after HLA-identical bone marrow transplantation in a patient with severe combined immunodeficiency with transplacentally acquired lymphoid chimerism

We describe a patient with severe combined immunodeficiency and transplacental transfer of maternal T cells who received an unfractionated HLA-identical sibling bone marrow transplant without prior conditioning. He presented prior to transplantation with a dermatitis later diagnosed as mild graft versus host disease. He had a normal absolute lymphocyte count, but proliferative responses to mitogens were very low. Antigens of the noninherited maternal HLA haplotype were detected on his blood lymphocytes. After transplantation, he developed a severe reaction including fever, cutaneous erythema and hepatosplenomegaly. Lymphocytes carrying the noninherited maternal HLA haplotype disappeared from his circulation, and his unprimed mononuclear cells became spontaneously cytotoxic to maternal lymphoblasts. He subsequently developed a lymphocytosis of 69,000/mm³, diarrhea, elevated transaminases and a worsening rash, necessitating treatment with immunosuppressive agents. Full T-cell engraftment and evidence of B-cell function later ensued and spontaneously cytotoxic lymphocytes against maternal cells disappeared by 47 days post-transplantation. We postulate that the patient's constellation of signs and symptoms after transplantation represented a combination of severe graft versus graft and mild graft versus host reactions.
