Stumpfe Schultergelenkverletzungen und ihre Begutachtung

It is difficult to assess blunt injuries in the region of the shoulder girdle because of the overlying acute and chronic processes. In assessments of rotator cuff ruptures in particular, in over 50% of cases the rupture could be explained by a degenerative process. This makes the assessment difficult, and also the decision as to whether or not the injury is due to an occupational accident. The diagnostic procedures applied should exclude a degenerative aetiology immediately after an accident in all cases. Rupture of the rotator cuff is often associated with an impingement syndrome and leads to corresponding symptoms in the subacromial space. Treatment of a rotator cuff rupture always involves a diagnostic arthroscopy as the first step, after which a reconstruction can be undertaken, either by way of the anterolateral approach after Neer or, in many cases, arthroscopically. Reconstruction of the rotator cuff must include outward mobilization of the muscles and a secure, mostly transosseous suture. Transference of a pedunculated tendon is indicated for large defects in the rotator cuff. In the case of dislocation of the shoulder with subsequent shoulder instability degenerative change and any possible multidirectional instability should be defined. Unidirectional instability with a demonstrable Bankart lesion has a good prognosis when surgery is performed without delay. In view of the high recurrence rate early treatment is indicated especially in young persons and in patients with a high activity level. Following detection of the Bankart lesion an arthroscopic procedure with refixation of the capsule–labrum complex is the method of choice.     

Reducing the risk of stroke in type 2 diabetes: pathophysiological and therapeutic perspectives

Reducing the excess cerebrovascular burden in patients with type 2 diabetes remains a major therapeutic challenge, especially with respect to the high risk of recurrent events. Targeting the traditional metabolic risk factors of hypertension, dyslipidemia, and hyperglycemia has failed to remove this excess risk, and agents targeting thrombotic risk (i.e., antiplatelet and anticoagulant drugs) remain poorly studied in the context of stroke in diabetes. This may relate to the accumulation of risk factors in type 2 diabetes as well as to diabetes-specific pathophysiologic factors. Regrettably, there is a lack of prospective evidence to support the efficacy of interventions in the secondary prevention of cerebrovascular events in type 2 diabetes, particularly recurrent stroke events. Overall, there is a need for rigorous evaluations of new therapeutic approaches in both primary and secondary prevention of stroke and management of acute stroke in patients with type 2 diabetes. This systematic review of the published literature summarizes the evidence regarding current therapeutic interventions and their impact on the risk of stroke in people with type 2 diabetes, and highlights potential strategies for improving outcomes.     

Dislocation of an upper third molar by an ossifying fibroma – Case report

BACKGROUND: The occurrence of ossifying fibromas (OFs) in childhood and adolescence has been described in the literature, along with different courses of the disease due to different growth rates. CASE REPORT: In the case of the 15-year-old female patient presented here, an OF resulted in displacement of a maxillary third molar far into the maxillary sinus. It is assumed that the tumour originated coronal to the affected tooth 18. Radiographs document an initial rapid growth of this tumour over a period of 2 years, while its growth almost completely ceased in the next 2 years immediately prior to diagnosis and surgical treatment. The operation was complicated by unexpected profuse bleeding from the tumour tissue. CONCLUSION: The peculiarity of the OF in the case presented here is its similarity, in terms of clinical and radiological appearances, with a follicular cyst, its unusual place of origin that resulted in the migration of the tooth 18 into the maxillary sinus, its different growth dynamics, and the pronounced haemorrhage encountered as the tumour was surgically removed.
