QUESTIONS/PURPOSES: Our primary objective of this report was to determine overall survivorship of a tita…

PURPOSE OF THE STUDY: We studied a cementless anatomic stem combination with a cementless press-fit cup. The purpose of this work was to assess prospectively in a homogeneous consecutive series of patients, the clinical and radiological outcome of this prosthesis at five years follow-up.

BACKGROUND: Expulsive hemorrhage is a severe complication of intraocular surgery. In a retrospective study we looked up surgical records of all penetrating keratoplasties (PK) performed in our department between 1989 and 1998. In all patients suffering from expulsive or preexpulsive choroidal hemorrhage we intended to…

OBJECTIVE: To evaluate the success rate and long-term outcome of cyclocryotherapy for refractory pediatric glaucoma. DESIGN: Retrospective interventional case series. PARTICIPANTS: A total of 64 eyes of 49 patients from 2 institutions with pediatric glaucomas resistant to conventional medical and surgical therapies t…

Bilateral trigeminal neuralgia is a rarely observed suffering. It is usually localised on one half of the face and few years after therapy or idiopathic regression it appears on the other side. In exceptional cases trigeminal neuralgia appears on both sides at the same time. Neurovascular decompression or neurotomy in…

The authors have reviewed 75 cases of infected Pseudarthrosis treated over the last five years (1989-1993) in the Septic Osteo Articular Pathology Unit (UP.S.O.A.) in the Orthopaedic Service of the Coimbra University Hospitals (H. U. C.).The primary objective was to cure infection, and the method of treatment was based…

Transluminal coronary angioplasty (TCA) was introduced in 1977 for dilatation of coronary stenoses. From October 1977 to December 1984 1087 procedures have been performed in Frankfurt. The mean success rate was 77% with an increase from 58% to 84% since 1977. Recurrences were seen within the first year in 15% of the pa…

Average age of the patients was 21.1 years. Five men and two women participated. Six lesions were in the right and one in the left upper e…

OBJECTIVE: To investigate the effectiveness of a suture bridge technique for quadriceps tendon rupture repair in uraemic patients. METHODS: Between March 2010 and September 2012, 10 uraemic patients (14 sides) with quadriceps tendon rupture were treated with the suture bridge technique. Of them, 8 were male and 2 were…

The mineral series glaucony supplies 40% of the absolute-age database for the geologic time scale of the last 250 million years. However, glauconies have long been suspected of giving young potassium-argon ages on bulk samples. Laser-probe argon-argon dating shows that glaucony populations comprise grains with a wide r…

The present article reviews the trends of tobacco use over the last 100 years and the public health strategies recently initiated to con…

BACKGROUND: Long-term outcome after surgical treatment of supratentorial ependymoma (STE) in children has not been extensively reported. FINDINGS: We identified 26 children who underwent primary tumor resection of STE between 1953 and 2011, with at least 8 years follow-up. Ten patients (38%) had anaplastic and 16 had…

It is estimated that by 2050, there will be a 300% increase in the elderly population (> or =65 years) and a corresponding increase in elderly patients presenting for surgical evaluation. Surgical decision-making in this population can be difficult because outcomes in the elderly are poorly defined. We reviewed 2698 co…

BACKGROUND: In the Ross procedure a valved conduit, most commonly pulmonary or aortic homograft, is used in place of autotransplanted pulmonary valve. Increasing demand and diminishing supply of homografts has resulted in a search for alternatives. A biological conduit from the valved segment of bovine jugular vein (Co…

Musculoskeletal disorders (MSDs) can be characterized from their occupational etiology and their occurrence; their chronicity generates negative repercussions for the health of workers, especially of artisanal fishing. To investigate the prevalence of generalized musculoskeletal disorders by body region and self-report…

BACKGROUND: A serum-free, highly purified Vero rabies vaccine (PVRV-NG) has been developed with no animal or human components and low residual DNA content. A phaseII randomized clinical study aimed to demonstrate the non-inferiority of the immune response and assess the safety profile of PVRV-NG versus a licensed human…
