Post-polio syndrome patients treated with intravenous immunoglobulin: a double-blinded randomized controlled pilot study

Post-polio syndrome (PPS) is characterized by new muscle weakness, atrophy, fatigue and pain developing several years after the acute polio. Some studies suggest an ongoing inflammation in the spinal cord in these patients. From this perspective, intravenous immunoglobulin (IvIg) could be a therapeutic option. We performed a double-blinded randomized controlled pilot study with 20 patients to investigate the possible clinical effects of IvIg in PPS. Twenty patients were randomized to either IvIg 2 g/kg body weight or placebo. Primary endpoints were changes in pain, fatigue and muscle strength 3 months after treatment. Surrogate endpoints were changes in cerebrospinal fluid (CSF) cytokine levels. Secondary endpoints were pain, fatigue and isometric muscle strength after 6 months. Patients receiving IvIg reported a significant improvement in pain during the first 3 months, but no change was noted for subjective fatigue and muscle strength. CSF levels of tumour necrosis factor- α (TNF- α ) were increased compared with patients with non-inflammatory neurological disorders. In conclusion, in this small pilot study no effect was seen with IvIg treatment on muscle strength and fatigue, however IvIg treated PPS patients reported significantly less pain 3 months after treatment. TNF- α was increased in the CSF from PPS patients. The results are promising, but not conclusive because of the low number of patients studied.     

股骨干骨折内固定术后不愈合27例分析

报告股骨干骨折切开复位内固定术后不愈合27例。其中，17例钢板固定者，只4例符合要求，9例髓内针固定者，有5例针短小。尚伴有固定方法，钢板或髓内针断裂，以及感染等方面原因有。本组再手术26例1次手术治愈，1例2次手术治愈。绝大部分经带蒂骨皮质剥离^[1]和坚强内固定术后而愈合，不需植骨。产生骨折不愈合的诸因素中，以忽视内固定的基本原则与术中操作不当为主。     

骨髓腔静脉造影在特发性股骨头坏死诊断中的应用

本文介绍17例（34髋）特发性股骨头坏死、4例（4髋）正常人骨髓腔静脉造影所见。发现25髋有异常改变,并经病理证实。作者认为:①骨干返流;②2支或2支以上静脉不显影;③多条静脉明显变细;④干骺端瘀积是股骨头坏死的造影表现,前二者是可靠的诊断依据。造影结果提示髓腔静脉造影是一种安全而敏感的诊断技术。     

Erfahrungen zur PFFB von isolierten radiusköpfchenfrakturen

Zusammenfassung Den Vorteilen einer osteosynthetischen Versorgung einer Fraktur mit sofortiger Aufnahme seiner Funktion, stehen die aus der Literatur bekannten Komplikationen gegenüber. Diese und unsere eigenen unbefriedigenden Ergebnisse nach der operativen Versorgung von Radiusköpfchenfrakturen ließen uns zu einer prospektiven randomisierten Studie einer primär funktionellen Behandlung unter Verzicht auf eine äußere oder innere Stabilisierung greifen. Seit Dezember 1991 haben wir im UKH-Graz bis einschließlich Dezember 1992 insgesamt 70 Patienten nach einem strikten Behandlungskonzept, unter Zuhilfenahme der Computertomographie zur Verlaufsbeobachtung versorgt. Die in 91% der Fälle als sehr gut and gut einzustufenden Frühergebnisse sowie das fehlende Auftreten einer, wie bei operativer Versorgung möglichen Komplikation, ebenso die zusätzlich deutlich frühere Arbeitsfähigkeit bzw. deutlich kürzere, wenn auch aufwendigere Behandlungszeit, lassen uns diese Verfahren nicht nur in unserem Hans weiterführen, sondern können wir auch weiter empfehlen.

Experience with internal fixation of fractures of the head of the radius

The advantages of internal fixation of fractures, with the possibility of immediate resumption of the function of the fractured bone, are in contrast to the well-known complications described in the literature. These complications and our own unsatisfactory results after surgical treatment of fractures of the head of the radius induced us to carry out a randomized prospective study of primary functional treatment of such fractures without external or internal stabilization. From December 1991 through December 1992, a total of 70 patients were treated according to a strict treatment protocol at the Graz Hospital for Accident Surgery, and CT was used for observation of the healing process. The positive early results, which in 91% of all cases were classified as very good or good, the lack of complications that sometimes follow surgical treatment, the markedly earlier recovery of the patient's working capacity, and the clearly shorter — albeit somewhat more expensive — treatment period required have led us to continue using this method at our hospital and also to recommend its use elsewhere.

     

Subcapital callus resection for slipped capital femoral epiphysis

Surgical Principles The lateral approach is routinely combined with an osteotomy of the greater trochanter. We resect the newly formed callus located at the anterior, posterior and caudal aspect of the femoral neck distal to the epiphysis. No shortening of the femoral neck results from this procedure. One can safely avoid a vascular injury by performing a careful dissection, since the posteriorly reflected articular capsule containing the nutrient vessels to the head is detached from the femoral neck like a banana peel. The resection manoeuvre is performed next to the physeal plate of the slipped epiphysis. After callus resection, reduction of the femoral head by longitudinal traction and internal rotation of the limb is easy. The aim is complete correction of the slippage. When there is excess physeal cartilage, we resect it with a curette and then the head is fixed using 2 screws. Revised Version from: Operat. Orthop. Traumatol. 4 (1992), 77–85 (German Edition).     

欧芹素乙和异欧芹素乙对小鼠腹腔巨噬细胞体外释放肿瘤坏死因子的抑制作用

研究了欧芹素乙（Ｉｍｐｅｒａｔｏｒｉｎ，Ｉｍｐ）和异欧芹素乙（Ｉｓｏ－ｉｍｐｅｒａｔｏｒｉｎ，Ｉｓｉ）及对照药物维拉帕米（Ｖｅｒａｐａｍｉｌ，Ｖｅｒ）对小鼠腹腔巨噬细胞体外释放肿瘤坏死因子（Ｔｕｍｏｒｎｅｃｒｏｓｉｓｆａｃｔｏｒ，ＴＮＦ）的影响。结果表明：Ｉｍｐ、Ｉｓｉ及Ｖｅｒ对小鼠腹腔巨噬细胞体外释放ＴＮＦ具有显著的抑制作用。药物浓度在１０－６～１０－４ｍｏｌ／Ｌ范围内，该抑制作用呈剂量依赖性：药物浓度达１０－４ｍｏｌ／Ｌ时，则可完全抑制ＴＮＦ的释放。
