Asymptomatic pneumoperitoneum or pneumatosis cystoides intestinalis? Easy to make a mistake.

Pneumoperitoneum refers to the presence of intraperitoneal free gas outside the viscera. A perforation of a hollow viscus is the main cause and usually indicates a surgical emergency. However, some case of pneumoperitoneum can be completely asymptomatic and secondary to benign conditions that do not require any surgical intervention.

Onycholemmal carcinoma: a morphologic comparison of 6 reported cases.

Background: We report 6 new cases of onycholemmal carcinoma, a rare, often misdiagnosed, subcategory of squamous cell carcinoma. All reported cases to date have been treated with amputation of the affected digit.

Objective: The purpose of this study was to present the clinical and pathological features of each new case and to discuss treatment options that spare digit functionality.

Bleeding control by radiofrequency in penetrating trauma of the liver.

Termocoagulation by radiofrequency (RF) is widely used for ablation of liver neoplasms. Recently, innovative uses of RF were proposed, as to assist liver resection, to help partial splenectomy, or to treat ruptured hepatocellular carcinoma. A 21 years old man was admitted for massive haemorrhage from a right thoraco-abdominal knife wound.

Treatment persistence with adalimumab, etanercept, or infliximab in combination with methotrexate and the effects on health care costs in patients with rheumatoid arthritis.

Background: Anti-tumor necrosis factor (TNF) biologic agents are effective in treating rheumatoid arthritis (RA). Information on patient persistence with biologic anti-TNF therapies is limited, and the effects of persistence on the costs of therapy are unknown.

Objectives: The aims of this study were to compare treatment persistence with adalimumab, etanercept, or infliximab in combination withmethotrexate (MTX) and evaluate the effects of persistence on overall health care costs.

A multicenter, randomized, open study to evaluate the impact of an electronic data capture system on the care of patients with rheumatoid arthritis.

Objective: To examine the impact of an electronic data capture system on patient satisfaction and patient-physician interactions in a rheumatology clinical setting.

Study Design: In this multicenter study, 1079 patients with rheumatoid arthritis completed questionnaires quarterly about their health and satisfaction with care using a computer. At 6 months, 901 eligible patients were randomized 2:1 to receive or not to receive graphical summarized health information or Health Tracker (HT) reports.
