OBJECTIVE: To present the functional and radiographic outcome 1 and 6 years after application of a new intramedullary fixation device for proximal humerus fractures. DESIGN: Retrospective case series. SETTING: Level II orthopaedic surgery hospital. PATIENTS: Twenty-six consecutive patients (average age 68.9 years) with 2-, 3- and 4-part fractures of the proximal humerus were operated at a single institution. Follow-up was performed after 1 year (26 patients) and 6 years (16 patients). INTERVENTION: All patients were treated with closed reduction and intramedullary helix wires. MAIN OUTCOME MEASUREMENTS: The Constant-Murley score and the University of California Los Angeles (UCLA) score. Clinical complications and radiological posttraumatic arthritis were recorded. RESULTS: The average Constant-Murley score was 70.3 (points) and 70.7 after 1 and 6 years, respectively; the average UCLA score was 27.2 and 31.5 after 1 and 6 years, respectively. Major complications were 4 revisions for 3 secondary fragment displacements and 1 nonunion with partial avascular osteonecrosis in the first postoperative year. Complications were found predominantly in 4-part fractures (3/5, 60%). There were no further complications or progressive posttraumatic arthritis up to 6 years following surgery. CONCLUSION: The helix wire is well suited for displaced or unstable 2- and 3-part proximal humerus fractures. Adequate functional outcome, a low number of implant displacements, a low number of application morbidity, and infrequent implant removals were recorded. The use of this device is not recommended for 4-part fractures.

Airway access is needed for a number of experimental animal models, and the majority of animal research is based on mouse models. Anatomical conditions in mice are small, and the narrow glottic opening allows intubation only with a subtle technique. We therefore developed a microscopic endotracheal intubation method with a wire guide technique in mice anaesthetized with halothane in oxygen. The mouse is hung perpendicularly with its incisors on a thread fixed on a vertical plate. The tongue is placed with a pair of forceps between the left hand's thumb and forefinger and slightly pulled, while the neck and thorax are positioned using the third and fourth fingers. By doing so, the neck can be slightly stretched, which allows optimal visualization of the larynx and the vocal cords. To ensure a safe intubation, a fine wire guide is placed under vision between the vocal cords and advanced about 5 mm into the trachea. An intravenous 22G x 1 in. plastic or Teflon catheter is guided over this wire. In a series of 41 mice, between 21 and 38 g, the success rate for the first intubation attempt was >95%. Certainty of the judgement procedure was 100% and success rate was higher using the described method when compared with a transillumination method in a further series. The technique is safe, less invasive than tracheostomy and suitable for controlled ventilation and pulmonary substance application.

Fillers are frequently used in beautifying procedures. Despite major advancements of the chemical and biological features of injected materials, filler-related adverse events may occur, and can substantially impact the clinical outcome. Filler granulomas become manifest as visible grains, nodules, or papules around the site of the primary injection. Early recognition and proper treatment of filler-related complications is important because effective treatment options are available. In this report, we provide a comprehensive overview of the differential diagnosis and diagnostics and develop an algorithm of successful therapy regimens.

Venous angioplasty with stenting of iliac veins is an important treatment option for patients suffering from post-thrombotic syndrome due to chronic venous obstruction. Interventional treatment of a chronically occluded vena cava, however, is challenging and often associated with failure. We describe a case of a chronic total occlusion of the entire inferior vena cava that was successfully recanalized using bidirectional wire access and a balloon puncture by a re-entry catheter to establish patency of the inferior vena cava.

The Wire, la serie concebida por David Simon a comienzo de la década pasada y emitida por HBO, es una de las pocas que puede presumir de ser llamada la mejor ficción creada para la televisión. Pero más allá de sus bondades artísticas, o precisamente por ellas, la mirada expansiva y total que realiza el programa sobre Baltimore, Maryland, en vísperas de nuestro siglo invita a que la utilicemos como punto de acceso para pensar el capitalismo, el crimen y la cuestión urbana en la actualidad. Pero por sobre todo, elaborar cómo estos términos interactúan en relaciones dialécticas que, en definitiva, producen la ciudad contemporánea
