Osteosynthesetechniken bei proximalen Humerusfrakturen

2001

Proximale Humerusfrakturen sind haufige Verletzungen. Die Frage der optimalen osteosynthetischen Behandlung instabiler und dislozierter 2- bis 4-Segmentfrakturen ist nach wie vor nicht einhellig geklart. Die operative Therapie befindet sich in der Konfliktsituation zwischen der Forderung einer anatomischen Reposition und stabilen Frakturretention auf der einen Seite und der Notwendigkeit einer maximalen intraoperativen Schonung der periglenohumeralen Weichteilstrukturen und Blutversorgung des Oberarmkopfs, mit dem Ziel das iatrogene Risiko der avascularen Kopfnekrose zu minimieren, andererseits. Wahrend Minimalosteosynthesen, bei denen die Reposition indirekt oder percutan erfolgt, Vorteile…

Preoperative preparation of «loss of domain» hernia. Progressive pneumoperitoneum and botulinum toxin type A.

2017

Preoperative progressive pneumoperitoneum and botulinum toxin type A are useful tools in the preparation of patients with loss of domain hernias. Both procedures are complementary in the surgical repair, especially with the use of prosthetic techniques without tension, that allow a integral management of these patients. The aim of this paper is to update concepts related to both procedures, emphasizing the advantages that take place in the preoperative management of loss of domain hernias.

Caspase-dependent cell death involved in brain damage after acute subdural hematoma in rats

2006

Abstract Traumatic brain injury is associated with acute subdural hematoma (ASDH) that worsens outcome. Although early removal of blood can reduce mortality, patients still die or remain disabled after surgery and additional treatments are needed. The blood mass and extravasated blood induce pathomechanisms such as high intracranial pressure (ICP), ischemia, apoptosis and inflammation which lead to acute as well as delayed cell death. Only little is known about the basis of delayed cell death in this type of injury. Thus, the purpose of the study was to investigate to which extent caspase-dependent intracellular processes are involved in the lesion development after ASDH in rats. A volume o…

Panniculitis due to potassium bromide.

1998

Potassium bromide again is well known to be surprisingly effective in patients with severe myoclonic epilepsy in infants (SME). Rare side effects on the skin reappeared, such as the febrile nodular panniculitis (Weber-Christian syndrome). In 1993 we described the first three cases of necrotizing panniculitis and introduced the term 'halogen panniculitis'. It is a systemic disease with crops of subcutaneous nodules, fever, elevated sedimentation rate, hepatosplenomegalia, and abdominal pain. Later severe necrosis of the skin and adipose tissue may happen with deep ulcerations. History and course of five cases, described in this paper, suggest either an allergy or toxic reason. Histologic pic…

The validity of the “liminf” formula and a characterization of Asplund spaces

2014

Abstract We show that for a given bornology β on a Banach space X the following “ lim inf ” formula lim inf x ′ ⟶ C x T β ( C ; x ′ ) ⊂ T c ( C ; x ) holds true for every closed set C ⊂ X and any x ∈ C , provided that the space X × X is ∂ β -trusted. Here T β ( C ; x ) and T c ( C ; x ) denote the β-tangent cone and the Clarke tangent cone to C at x. The trustworthiness includes spaces with an equivalent β-differentiable norm or more generally with a Lipschitz β-differentiable bump function. As a consequence, we show that for the Frechet bornology, this “ lim inf ” formula characterizes in fact the Asplund property of X. We use our results to obtain new characterizations of T β -pseudoconve…

Abstract. The dynamics of growing collisional orogens are mainly controlled by buoyancy and shear forces. However, the relative importance of these forces, their temporal evolution and their impact on the tectonic style of orogenic wedges remain elusive. Here, we quantify buoyancy and shear forces during collisional orogeny and investigate their impact on orogenic wedge formation and exhumation of crustal rocks. We leverage two-dimensional petrological–thermomechanical numerical simulations of a long-term (ca. 170 Myr) lithosphere deformation cycle involving subsequent hyperextension, cooling, convergence, subduction and collision. Hyperextension generates a basin with exhumed continental m…

Surface Reconstruction Based on a Descriptive Approach

2000

The design of complex surfaces is generally hard to achieve. A natural method consists in the subdivision of the global surface into basic surface elements. The different elements are independently designed and then assembled together to represent the final surface. This method requires a classification and a formal description of the basic elements. This chapter presents a general framework for surface description, based on a constructive tree approach. In this tree the leaves are surface primitives and the nodes are constructive operators.

Development of Abdominal Aortic Aneurysm Is Decreased in Mice with Plasma Phospholipid Transfer Protein Deficiency

2013

International audience; Plasma phospholipid transfer protein (PLTP) increases the circulating levels of proatherogenic lipoproteins, accelerates blood coagulation, and modulates inflammation. The role of PLTP in the development of abdominal aortic aneurysm (AAA) was investigated by using either a combination of mechanical and elastase injury at one site of mouse aorta (elastase model) or continuous infusion of angiotensin II in hyperlipidemic ApoE-knockout mice (Ang II model). With the elastase model, complete PLTP deficiency was associated with a significantly lower incidence and a lesser degree of AAA expansion. With the Ang II model, findings were consistent with those in the elastase mo…

POTENTIAL NEW GENETIC AND BIOCHEMICAL MARKERS OF CHRONIC KIDNEY FAILURE

2017

disease (CKD) is an important source of long-term morbidity and mortality. It has been estimated that CKD affects more than 20 million people in the United States. Given that most patients are asymptomatic until the disease has significantly progressed, they remain unaware of the condition. Thus, it is essential to have clinical practice guidelines (BIOMARKERS aimed at early detection, evaluation, diagnosis, and treatment of this condition.
