    Notes: Abstract The genes coding for the outer surface protein A (OspA) of 19 different Borrelia burgdorferi strains belonging to the seven OspA-serotypes 1–7, previously described [Wilske et al. (1993) J Clin Microbiol, 31: 340–350], have been investigated. B. burgdorferi sensu lato strains were chosen from various biological sources (ticks, human skin and cerebrospinal fluid) as well as different geographical origins (Germany, Slovenia, Austria, United States). The open reading frames of all ospA genes consist of 819–825 nucleotides corresponding to proteins of approximately 30 kDa. The ospA sequences obtained in this study and previous published studies were compared with the results from OspA serotyping with monoclonal antibodies. The classification into the seven OspA serotypes could be confirmed on a genetic basis (ospA genotypes 1–7) for all strains analyzed so far (n=29). In addition, one strain without OspA expression could be assigned to ospA genotype 2. Genetic stability could be proven for the ospA gene of B. burgdorferi strain PWudI after inocculation and reisolation from a gerbil. However, we found evidence for intragenic recombination by cluster analysis of ospA sequence data. Accordance of ospA genotype 1 strains with B. burgdorferi sensu stricto and ospA genotype 2 strains with B. afzelii, as well as the ospA genotype strains 3–7 with B. garinii was confirmed by pulsed-field gel electrophoresis of MluI-digested genomic DNA. B. garinii is not only more heterogenous in respect to the OspA-encoding genes, but shows moreover major subgroups formed by genotypes 4, 5 and 6 and genotypes 3 and 7, respectively. The latter group has not been described previously and is specifically recognized by an OspA-specific monoclonal antibody L32 1F7.

    Notes: Abstract The ospC gene coding for the outer surface protein OspC and the fla gene coding for the flagellin have been investigated in three different Borrelia burgdorferi sensu lato strains. These strains (the North American strain B31 and the European strains PKo and PBi) derive from various biological sources (lxodes dammini, human skin and human CSF) and belong to three different B. burgdorferi OspA serotypes and genospecies (OspA serotype 1, B. burgdorferi sensu stricto; OspA serotype 2, group VS461 and OspA serotype 4, B. garinii, respectively). The ospC and fla genes of the respective strains have been amplified by polymerase chain reaction, cloned in pUC8 and sequenced. The fla as well as the ospC genes were different among the three strains investigated. In general the fla genes are more conserved than the ospC genes. The fla genes have the same length of 1008 nucleotides coding for proteins of 336 amino acids, whereas the ospC genes differ in length. The ospC genes of strains B31, PKo and PBi have 630, 636 and 621 nucleotides encoding proteins of 210, 212 and 207 amino acids, respecctively. The ospC genes exhibit sequence identities between 70% and 74% among each other, sequence identities of the fla genes are in the range 96–97%. The ospC genes could be expressed in Escherichia coli to obtain proteins with and without leader peptides. The expression of the fla gene and an internal gene fragment resulted in the complete flagellin protein and a truncated protein (amino acids 129–251). The different ospC and fla gene products were immunoreactive with monoclonal antibodies and human sera and, thus, enlarge the spectrum of recombinant antigens to improve antibody detection in patients with Lyme borreliosis.

    Notes: Summary The fluid composition of five epididymal spermatocoeles, one epididymal cyst and a hydrocoele was examined. The fluid obtained from the spermatocoeles was a dilute suspension of mainly immotile spermatozoa. The sperm-free fluid contained less protein, phosphate, glucose, triglyceride and cholesterol than serum but more testosterone and chloride than peripheral blood. It contained no epididymal secretion products. Proteins in the fluid differed from those in serum. From the fluid composition these cysts appeared to be continuous with the rete testis, either dilatations of efferent ducts or Haller's superior aberrant duct (vas aberrans of the rete testis). Fluid from an epididymal cyst containing no spermatozoa was mainly of similar composition. In contrast, hydrocoele fluid resembles blood serum.

    Description / Table of Contents: Betula maximowicziana (provenances from Hokkaido and Hondo, Japan) were sown in 1959. The seedlings were planted one year later in Großhansdorf/Schleswig-Holstein. At the age of 35 years 20 trees were felled. The butt and top logs of each tree were used for the determination of the following wood properties: density, modulus of elasticity, bending, compression and tension strength, impact bending and hardness. The results are tabulated. With the reservation that the trees were all of the same age from only one site, the wood properties of the Japanese birch are equivalent to those of the two European birches B. pendula and B. pubescens.
    Notes: Betula maximowicziana (Herkünfte von Hokkaido und Hondo, Japan) wurden im Jahre 1959 ausgesät und die Jungpflanzen ein Jahr später in Großhansdorf/Schleswig-Holstein ausgepflanzt. Im Alter von 35 Jahren wurden 20 Bäume eingeschlagen, von denen ein unterer und ein oberer Stammabschnitt zur Untersuchung der Holzeigenschaften dienten. Die Ergebnisse der Rohdichte, der Elastizitätsmoduln, der Festigkeiten, der Bruchschlagarbeit und der Härte werden angegeben. Daraus läßt sich–mit allem Vorbehalt, der bei der Untersuchung von Holz eines Standortes und eines Baumalters erforderlich ist–folgern, daß das Holz der Maximowicz-Birke in seinen technologischen Eigenschaften nicht von dem der beiden europäischen Birken (B. pendula und B. pubescens) abweicht.

    Notes: Im Holz der immissionsbelasteten und entsprechend zwar physiologisch geschwächten, aber nicht sekundär geschädigten Fichten konnte dagegen keine Beeinträchtigung der Bruch- schlagarbeit festgestellt werden. Aus den Untersuchungen geht hervor, daß das Holz von Fichten aus extrem immissionsbelasteten Hochlagenstandorten des Osterzgebirges nach sorgfältiger Aussortierung von sekundär geschädigten Einzelbäumen uneingeschränkt verwendet werden kann.

    Description / Table of Contents: Fractures and dislocations of the elbow are some of the most common injuries in childhood and adolescence. The majority occur in sport and play activities, e. g., a fall from gymnastics apparatus or a bike, or from popular sports items, such as skateboards or in-line skates. The injuries can be divided into pure dislocations of the joint and fractures of the distal humerus, proximal radius and ulna, or combinations of both. In addition, extra- and intraarticular fracture types are defined, with the latter as partial or complete joint lesions. Dislocations of the elbow joint or the radial head can occur as single injuries or in combination with a fracture. Supracondylar fractures and avulsion fractures of the medial epicondyle are the most frequent extraarticular lesions of the distal humerus. Fractures of the lateral condyle prevail is incomplete intraarticular lesions. In the forearm, radial head and neck fractures are predominant while typical and atypical Monteggia injuries have a special status. The complex joint construction and the age-dependent appearance of the epiphyseal ossification centers sometimes make a correct radiological diagnosis difficult. The trauma history and an exact, clinical examination help to verify the injury, as do comparative X-ray studies of the uninjured side when necessary (but not routinely). Unlike other anatomical areas, most elbow injuries – even in the growing skeleton – are treated operatively. Hereby, the growth plates have to be respected using minimal amounts of small implants. Additional immobilization in a cast for 2 – 4 weeks is necessary in most cases but does not lead to a functional deficit – in contrast to adults. The implants should be removed as early as possible. Despite all therapeutic efforts, a significant number of late sequelae, such as malunions and functional impairment, can be seen. The rate of long-term complications increases in cases of untreated displacement of fragments or joint instability. Corrective measures are performed only in selected cases and after the growth plates are closed. Our own treatment regime is demonstrated using exemplary clinical cases of the different injuries and the results of a long-term follow-up study on sports injuries of the elbow in children. Errors in diagnosis and therapy, as well as possible complications, are pointed out.
    Notes: Luxationen und/oder Frakturen am Ellenbogen während des Wachstums gehören zu den häufigsten Verletzungen dieser Altersgruppe überhaupt. Sie entstehen mehrheitlich bei Sport und Spiel, beispielsweise durch Sturz von einem Turngerät, von Fahrrädern oder bei Ausübung moderner Trendsportarten wie In-line-Skating, Rollschuhlauf und Skateboard. An Verletzungen unterscheidet man reine Luxationen von Frakturen, welche entweder am körperfernen Oberarmende oder an den gelenkbildenden Anteilen von Radius und Ulna lokalisiert sind. Darüber hinaus werden extra- von intraartikulären Bruchformen abgegrenzt, wobei letztere das Gelenk entweder partiell oder auch komplett tangieren. Luxationen des Ellenbogengelenks oder des Radiusköpfchens können isoliert oder in Kombination mit einer Fraktur vorkommen. Die häufigsten Verletzungen am distalen Humerus sind die suprakondyläre Humerusfraktur und der Ausriß des Epicondylus medialis als extraartikuläre sowie die Fraktur des Kondylus lateralis als inkomplette intraartikuläre Verletzung. Am Unterarm sind Brüche an Speichenköpfchen und -hals zahlenmäßig vorherrschend. Eine Sonderstellung nehmen typische und atypische Monteggia-Läsionen ein. Infolge des komplizierten Gelenkaufbaus und des zeitversetzten Auftretens der einzelnen Knochenkerne ist die radiologische Diagnostik gelegentlich schwierig. Die Anamnese und eine exakte klinische Untersuchung, bei Bedarf (nicht routinemäßig!) Vergleichsaufnahmen der gesunden Gegenseite erleichtern die Verifizierung der Verletzung. Im Gegensatz zu anderen anatomischen Regionen werden Verletzungen am Ellenbogen auch im Wachstumsalter mehrheitlich operativ versorgt. Dabei sind die Epiphysenfugen zu respektieren, die Implantate werden frühzeitig wieder entfernt, eine mehrwöchige Gipsruhigstellung bleibt im Unterschied zum Erwachsenen beim Kind ohne nennenswerte Funktionseinbuße. Trotz aller therapeutischer Bemühungen sind in einem nicht unerheblichen Prozentsatz Spätschäden in Form von Achsenfehlern und Funktionsbehinderungen zu beobachten. Eine insuffiziente Therapie mit belassener Fehlstellung oder Instabilität erhöht die Rate von Langzeitkomplikationen beträchtlich. Korrekturmaßnahmen werden regelhaft erst nach Wachstumsabschluß und bei strenger Indikationsstellung vorgenommen. Anhand charakteristischer Kasuistiken und einer Nachuntersuchung von Sportverletzungen am Ellenbogengelenk soll das eigene Vorgehen dargestellt und auf Behandlungsfehler bzw. Komplikationsmöglichkeiten hingewiesen werden.
