PURPOSE The purpose of our study was to evaluate the usefulness of magnetic resonance imaging (MRI) in the follow-up of patients treated with collagen meniscus implant (CMI) and to identify MRI patterns suitable for defining its evolution. MATERIALS AND METHODS Between March 2001 and June 2003, CMI was performed on 40 patients (27 men and 13 women, age(More)
Ankle impingement is defined as entrapment of an anatomic structure that leads to pain and decreased range of motion of the ankle and can be classified as either soft tissue or osseous (Bassett et al. in J Bone Joint Surg Am 72:55-59, 1990). The impingement syndromes of the ankle are a group of painful disorders that limit full range of movement. Symptoms(More)
BACKGROUND Central diabetes insipidus is rare in children and young adults, and up to 50 percent of cases are idiopathic. The clinical presentation and the long-term course of this disorder are largely undefined. METHODS We studied all 79 patients with central diabetes insipidus who were seen at four pediatric endocrinology units between 1970 and 1996.(More)
BACKGROUND The acute scrotum is a medical emergency . The acute scrotum is defined as scrotal pain, swelling, and redness of acute onset. Scrotal abnormalities can be divided into three groups , which are extra-testicular lesion, intra-testicular lesion and trauma. This is a retrospective analysis of 164 ultrasound examination performed in patient arriving(More)
PURPOSE The aim of this study was to analyse factors predicting the diagnostic accuracy of computed tomography (CT)-guided transthoracic fine-needle aspiration (TTFNA) for solid noncalcified, subsolid and mixed pulmonary nodules, with particular attention to those responsible for false negative results with a view to suggesting a method for their(More)
The term "biceps brachii" is a Latin phrase meaning "two-headed (muscle) of the arm." As its name suggests, this muscle has two separate origins. The short head of biceps is extraarticular in location, originates from the coracoid process of the scapula, having a common tendon with the coracobrachialis muscle. The long head of biceps tendon (LBT) has a much(More)
PURPOSE This study was undertaken to evaluate magnetic resonance (MR) arthrography in the detection and classification of lesions that may cause superior instability. MATERIALS AND METHODS Forty-two consecutive patients with clinical signs of chronic superior instability of the shoulder underwent MR arthrography followed by arthroscopic surgery. For each(More)
OBJECTIVE Magnetic resonance imaging (MRI) without contrast medium is unable to give detailed information on the hypothalamic-pituitary structures. MRI using gadopentetate dimeglumine (Gd-DTPA), and dynamic MRI, were performed in patients with hypopituitarism previously diagnosed as having anterior pituitary hypoplasia, ectopic posterior pituitary and(More)
Children treated for Langerhans cell histiocytosis (LCH) are at risk for short and long term endocrine sequelae, but biological predictors of specific deficits are not well defined. We evaluated the frequency and progression of LCH-related endocrine deficits during long term follow-up and assessed the ability of dynamic endocrine testing to identify(More)
We examined 14 patients, aged 10-25 years, with idiopathic hypopituitarism. All presented an ectopic posterior pituitary at the median eminence with a hypoplastic anterior pituitary on magnetic resonance imaging (MRI). Eight patients had isolated growth hormone deficit (IGHD) and six had multiple hormone deficits (MPHD). Unenhanced MRI showed the pituitary(More)
