Combination of glycolic acid peel and topical 20% azelaic acid cream in melasma patients: efficacy and improvement in quality of life.

Background: Glycolic acid (GA) peel is one of the most versatile agents in the treatment of melasma. GA peeling alone or in combination with topical hypopigmenting agents has shown encouraging results. However, there is paucity of controlled trial demonstrating the efficacy of glycolic peel in conjunction with topical azelaic acid (AA).

Computed tomography-guided percutaneous needle biopsy of indeterminate pulmonary pathology: efficacy of obtaining a diagnostic sample in immunocompetent and immunocompromised patients.

Purpose: We aimed to evaluate the efficacy of computed tomography (CT)-guided percutaneous lung biopsy of pulmonary nodules with indeterminate radiologic characteristics in patients at risk for malignant and nonmalignant processes such as infection or inflammation.

Patients And Methods: From January 2003 to September 2008, 262 patients (mean age, 59 years; range, 18-92 years) with pulmonary nodules or a mass of uncertain etiology and with indeterminate radiologic characteristics underwent CT-guided percutaneous lung biopsy. Patients with discordant clinical history and imaging findings or immunocompromised patients at risk for both etiologies were included.

Pelvic congestion syndrome: diagnosis and treatment.

The diagnosis of pelvic congestion syndrome (PCS) continues to challenge all physicians involved especially those in such specialties as anesthesia, gastroenterology, general surgery, obstetrics and gynecology, and interventional radiology. When other pelvic pathology is ruled out, an interventional radiologist may be consulted for additional evaluation and treatment of PCS. A heightened awareness and clinical suspicion for the specific symptomatology and associated findings may bring about a more rapid progression toward treatment.
