Infraspinatus Kontraktur beim Cavalier King Charles

Ein 6,5 Jahre alter Cavalier King Charles Spaniel wurde mit einer seit 6 Wochen bestehenden Lahmheit der linken Vorderextremität vorgestellt. In der klinischen Untersuchung wurden eine Abduktion der linken Vordergliedmaße, eine Atrophie des M. infraspinatus, M. supraspinatus und M. deltoideus, eine Dolenz bei Palpation bzw. Flexion des Schultergelenks sowie eine mittelgradige Hangbeinlahmheit mit charakteristischer Aussenrotation der Schulter festgestellt. Als Diagnose wurde eine Kontraktur des M. infraspinatus gestellt, und die komplette Tenektomie seiner Ansatzsehne führte zur Wiederherstellung der normalen Gliedmaßenfunktion.

Mutation in beta1-tubulin correlates with macrothrombocytopenia in Cavalier King Charles Spaniels.

BACKGROUND Cavalier King Charles Spaniels (CKCS) have a high prevalence of inherited macrothrombocytopenia. The purpose of this study was to determine if a mutation in beta1-tubulin correlated with presumptive inherited macrothrombocytopenia. HYPOTHESIS A mutation in beta1-tubulin results in synthesis of an altered beta1-tubulin monomer. alpha-beta tubulin dimers within microtubule protofilaments are unstable, resulting in altered megakaryocyte proplatelet formation. ANIMALS Blood samples were obtained from CKCS and non-CKCS dogs. METHODS DNA was used in polymerase chain reaction (PCR) assays to evaluate beta1-tubulin. Platelet numbers and mean platelet volume (MPV) were evaluated for a correlation with the presence or absence of a mutation identified in beta1-tubulin. Platelets obtained from homozygous, heterozygous, and clear CKCS were further evaluated using electron microscopy and immunofluorescence. RESULTS A mutation in the gene encoding beta1-tubulin correlated with macrothrombocytopenia in CKCS. Electron microscopy and immunofluorescence studies suggest that platelet microtubules are present but most likely are unstable and decreased in number. CONCLUSIONS AND CLINICAL IMPORTANCE The macrothrombocytopenia of CKCS correlated with a mutation in beta1-tubulin. alpha-beta tubulin dimers within protofilaments most likely are unstable, leading to altered proplatelet formation by megakaryocytes. This information will aid in distinguishing inherited from acquired thrombocytopenia. It also provides insight into the mechanism of platelet production by megakaryocytes, and also may prove useful in understanding heart-related changes in macrothrombocytopenic CKCS with concurrent mitral valve regurgitation.

The Alexander Technique and musicians: a systematic review of controlled trials

BACKGROUND: Musculoskeletal disorders, stress and performance anxiety are common in musicians. Therefore, some use the Alexander Technique (AT), a psycho-physical method that helps to release unnecessary muscle tension and re-educates non-beneficial movement patterns through intentional inhibition of unwanted habitual behaviours. According to a recent review AT sessions may be effective for chronic back pain. This review aimed to evaluate the evidence for the effectiveness of AT sessions on musicians' performance, anxiety, respiratory function and posture. METHODS: The following electronic databases were searched up to February 2014 for relevant publications: PUBMED, Google Scholar, CINAHL, EMBASE, AMED, PsycINFO and RILM. The search criteria were "Alexander Technique" AND "music*". References were searched, and experts and societies of AT or musicians' medicine contacted for further publications. RESULTS: 237 citations were assessed. 12 studies were included for further analysis, 5 of which were randomised controlled trials (RCTs), 5 controlled but not randomised (CTs), and 2 mixed methods studies. Main outcome measures in RCTs and CTs were music performance, respiratory function, performance anxiety, body use and posture. Music performance was judged by external experts and found to be improved by AT in 1 of 3 RCTs; in 1 RCT comparing neurofeedback (NF) to AT, only NF caused improvements. Respiratory function was investigated in 2 RCTs, but not improved by AT training. Performance anxiety was mostly assessed by questionnaires and decreased by AT in 2 of 2 RCTs and in 2 of 2 CTs. CONCLUSIONS: A variety of outcome measures have been used to investigate the effectiveness of AT sessions in musicians. Evidence from RCTs and CTs suggests that AT sessions may improve performance anxiety in musicians. Effects on music performance, respiratory function and posture yet remain inconclusive. Future trials with well-established study designs are warranted to further and more reliably explore the potential of AT in the interest of musicians.

Pharao Haremhab und die nördliche Levante. Bemerkungen zu einem Skarabäenabdruck aus Tall Mishrife/Qatna

This paper deals with a clay sealing which seems to feature one scarab impression with the personal name of Pharaoh Haremhab, last king of the 18th Dynasty (ca. 1319/1305?–1292 BCE). The clay sealing was found in a pit within the central area of the Royal Palace of Qaṭna. The impression thus could shed new light on the chronology of the palace, as well as Haremhab´s political involvement in the northern Levant.
