Early osteointegration in "one-step" resection and reconstruction using porous hydroxyapatite custom implants for skull-infiltrating tumors: a monocentric prospective series.

Background: Early reconstruction of the skull represents the gold standard after resection of bone infiltrating cranial tumors. Customized hydroxyapatite porous ceramics are an excellent option for covering skull bone defects. The authors illustrate the surgical technique and investigate the effectiveness of the "one-step" procedure in terms of aesthetic results and early degree of osteointegration.

Case report of Kummell's disease with delayed onset myelopathy and the literature review.

Introduction: Kummell's disease is an avascular necrosis of the vertebral body, secondary to a vertebral compression fracture. This entity is characterised by the gradual development in time of a vertebral body collapse following a trivial spinal trauma, involving a worsening back pain associated with a progressive kyphosis.

Purposes: The aim of this article is to carry out an international literature review regarding Kummell's disease, addressing its physiopathology, histopathology, clinical presentation, radiological characteristics and treatment modalities; at the same time, the literature is updated through the description of a new and interesting case, symbol of the pathology long-term potential complications, if not diagnosed and therefore not suitably treated.

Cervicothoracic postarachnoiditic hydrosyringomyelia secondary to pedicular hook dislocation: case report.

Background: Pedicular hook dislocation is a rare complication of spinal instrumentation. We report on the first case of hydrosyringomyelia secondary to intracanalar hook displacement after scoliosis surgery.

Case Description: A 15-year-old girl presented to our institution with a 7-month history of persistent neck and occipital pain as well as numbness of the lower extremities and previous dorsolumbar instrumentation with dorsal pedicular hooks and lumbar screws.

[GPs' self-perception of their own role compared with hospital, ambulatory, academic, and health organisation physicians].

Aim of the present study was to explore how the 76 general practitioners (GPs) - serving Carpi district (90,000 residents) - value their own role compared with the hospital, ambulatory, academic, and health organisation physicians'. GPs had a positive self-image only in comparison with health organisation doctors (7 vs 7 grades). GPs disappointed with themselves when comparing their role with ambulatory (-1.
