Doxycycline-induced ulceration mimicking esophageal cancer.

Introduction: Doxycycline-induced esophageal ulcer patients are mostly young persons with no history of esophageal dysfunction. Heartburn, midsternal pain and dysphagia are the most common symptoms. It has generally a benign course.

[Production and characterization of a glass-ceramic biomaterial and in vitro and in vivo evaluation of its biological effects].

Objectives: Glass-ceramics are biomaterials that are usually produced by the sol-gel technique and can be used as a substitute for bone. One important feature of glass-ceramics is osteointegration with bone tissue. This study was designed to produce a glass-ceramic and evaluate its structure and in vitro and in vivo biological effects.

Inhibitory effect of alendronate on bone resorption of autogenous free bone grafts in rats.

Purpose: This study was designed to investigate the effect of alendronate on the resorption of autogenous free bone grafts by biochemical and histopathologic methods. Alendronate is a potent inhibitor of osteoclast-mediated bone resorption with no adverse effect on the mineralization of bone.

Materials And Methods: In this experimental study, 56 male Wistar rats were used.

Primary hydatid disease of the femur: unsuspected and incidental MRI findings with long-term curative results on medical treatment alone.

This report describes the early magnetic resonance imaging (MRI) findings and long-term follow-up results of albendazole treatment in a 16-year-old girl with primary hydatid disease of the femur diagnosed incidentally during the course of a post-traumatic knee infection. As far as we know, this is the first report of the early MRI findings and long-term outcome of medical treatment in primary hydatid disease of the femur in this age group.

An anatomopathologic study of membranous septum aneurysms and significance of their surgical treatment.

The Purpose Of The Study: We analyzed 14 patients with membranous septal aneurysms presenting with a left-to-right communication, by comparing the angiographic, operative and pathological findings. We decided to use medical treatment on two patients and operated on the rest (12 cases).

Basic Methods: The mean age of the patients was 19+/-9 yr; nine were female, five were male.

Vertebral sarcoidosis: imaging findings.

Sarcoidosis is a multisystemic disease of unknown aetiology characterised by noncaseating granulomatous inflammation with varying presentation and prognosis. Osseous disease reported in 1-13 % of cases commonly involves hands and feet; however, vertebral sarcoidosis is rare. This report describes the radiologic, CT, MRI and radionuclide imaging findings of vertebral involvement of a case with sarcoidosis.

Langerhans cell histiocytosis in an adult.

We present the case of a 27-year-old Caucasian woman who suffered from Langerhans cell histiocytosis with axillary and scalp involvement. She also developed diabetes insipidus after 2 years of skin lesions. Topical nitrogen mustard therapy was performed for the skin lesions, but we had to stop this therapy because of severe local irritation and systemic urticaria.
