Can "presumed consent" justify the duty to treat infectious diseases? An analysis.

Background: AIDS, SARS, and the recent epidemics of the avian-flu have all served to remind us the debate over the limits of the moral duty to care. It is important to first consider the question of whether or not the "duty to treat" might be subject to contextual constraints. The purpose of this study was to investigate the opinions and beliefs held by both physicians and dentists regarding the occupational risks of infectious diseases, and to analyze the argument that the notion of "presumed consent" on the part of professionals may be grounds for supporting the duty to treat.

Angiokeratoma of clitoris: a rare lesion in an adolescent girl.

Angiokeratoma is a benign vascular lesion. It is the result of dilation of ectatic subdermal vessels and congested capillaries. Weakness of the vessel walls, either from acquired or congenital reasons, can cause formation of the lesion.

An unusual cause of paraphimosis: hemangioma of the glans penis.

Paraphimosis is a urologic emergency that occurs in uncircumcised boys. In untreated paraphimosis, increasing edema caused by vascular and lymphatic obstruction results in ominous sequelae such as penile gangrene, which leads to autoamputation in days or weeks. Most cases of paraphimosis are iatrogenic, but that condition has unusual causes as well.

Do patients have responsibilities in a free-market system? A personal perspective.

The current debate that surrounds the issue of patient rights and the transformation of health care, social insurance, and reimbursement systems has put the topic of patient responsibility on both the public and health care sectors' agenda. This climate of debate and transition provides an ideal time to rethink patient responsibilities, together with their underlying rationale, and to determine if they are properly represented when being called 'patient' responsibilities. In this article we analyze the various types of patient responsibilities, identify the underlying motivations behind their creation, and conclude upon their sensibleness and merit.

Moxifloxacin versus ampicillin + gentamicin in the therapy of experimental Listeria monocytogenes meningitis.

Objectives: This study aimed to compare the antibacterial activity of moxifloxacin and ampicillin + gentamicin in the treatment of Listeria monocytogenes meningitis in a rabbit meningitis model.

Renal parenchymal malacoplakia: a different stage of xanthogranulomatous pyelonephritis?

Malacoplakia is a rare inflammatory condition characterized by demonstrative Michaelis-Gutmann bodies, which are foamy histiocytes with distinctive basophilic inclusions. Malacoplakia is caused by the inadequate elimination of bacteria by macrophages or monocytes as a result of defective phagocytic activity. Xanthogranulomatous pyelonephritis is characterized by the destruction of renal parenchyma and its replacement by solid sheets of foamy lipid-laden macrophages.
