RESUMO
We present a brief report of an 81-year-old man with a pretreated leiomyosarcoma of the skull. Histologically the diagnosis of a dedifferentiated cutaneous leiomyosarcoma with an infiltration of the skull was confirmed. In an interdisciplinary approach together with the University Clinic for Neurosurgery, complete removal of the tumour was performed. Cutaneous leiomyosarcoma are rare tumors of the skin and typically present as slowly growing erythematosus nodes. Because of the risk of metastatic spread, complete micrographically confirmed resection is necessary.

Vasculitis and vasculopathy are two distinct disease entities. Each entity comprises a large number of heterogeneous diseases, which can occur alone or associated with autoimmune, infectious or neoplastic diseases. The terms vasculitis and vasculopathy are often falsely used synonymously. A vasculitis initially causes inflammation of the vessel walls that may result in a secondary occlusion. In contrast, a vasculopathy is a primary occlusion of the vascular lumen, which is followed by inflammation after ischemia and ulceration. In most patients the distinction can be made based on the clinical presentation. A clear clinical diagnosis is then followed by targeted serological, histological and imaging procedures to confirm the clinical diagnosis. On this basis a well-founded treatment can be initiated. In the presence of vasculitis an anti-inflammatory therapy is indicated, whereas in the case of vasculopathy, removal of the vascular occlusion is the main focus. This article provides an overview of the various diseases and addresses the pathogenetic and clinical characteristics used to differentiate the individual disease entities. It also provides an insight into the therapy options and prophylaxis.

Case. Compartment syndrome following muscle rupture is a rare entity with few mentions in the literature. We present a case of pectoralis major rupture in a 38-year-old male that evolved into compartment syndrome of the anterior compartment of the arm. Rupture of the pectoralis is uncommon and most often occurs during weight lifting. Compartment syndrome secondary to this injury is extremely uncommon, with only one reported case in the pectoralis major itself and several cases of biceps compartment syndrome. Due to the potentially devastating consequences of a missed compartment syndrome, it is imperative that physicians maintain a high level of suspicion in patients with these unusual injuries presenting with severe swelling and pain.
RESUMO
Avaliou-se o efeito da utilização de níveis crescente de minerais orgânicos sobre a qualidade externa e interna de ovos e a resistência de ossos da tíbia de poedeiras semi-pesadas. Foram utilizadas 256 aves, com idade inicial de 30 semanas, distribuídas em 64 gaiolas perfazendo quatro aves por gaiola em delineamento inteiramente ao acaso. Os tratamentos consistiram da inclusão de minerais inorgânicos ou níveis crescentes de orgânicos na dieta basal das poedeiras, resultando em quatro tratamentos. Foram avaliados peso do ovo (g), gravidade específica, peso (g) e espessura (mm) da casca, altura do albúmen (mm), unidade Haugh, peso da gema (g) e do albúmen (g) e resistência óssea (kg). Houve diferença significativa (P>0,05) entre as médias para peso do ovo e do albúmen. O fornecimento de dietas suplementadas com minerais orgânicos, em nível intermediário resultou na produção de ovos mais pesados, com maior peso de albúmen, e na manutenção das demais características de qualidade externa e interna dos ovos e de resistência óssea.
The effect of increasing levels of organic minerals on the external and internal quality of eggs and tibia bone strength of brown-egg laying hens was studied. A total of 256, 30-week old was equally distributed in 64 cages in a total of four birds per cage in a completely randomized experimental design. The dietary treatments consisted of inorganic or increasing levels of organic minerals in the diets of laying hens, resulting in four treatments. Egg weight (g), specific gravity, shell weight and thickness (mm), albumen height (mm), Haugh unit, yolk weight and albumen (g) and bone strength (kg) were evaluated. A significant difference (P<0.05) among treatment means for egg weight and albumen was found. Intermediate inclusion levels of organic minerals resulted in the production of heavier eggs, with higher albumen weight and maintenance of the other characteristics of internal and external quality of eggs and bone strength.
