Psoriasis in obesity: comparison of serum levels of leptin and adiponectin in obese subjects - cases and controls.

Background: Psoriasis and obesity are somewhat related to a low-grade systemic inflammatory response.

Objectives: To determine leptin and adiponectin levels in psoriasis patients compared to control patients matched for weight.

Methods: A case-control study was performed, evaluating 113 psoriasis patients and 41 controls with other dermatologic diseases.

Assessment of adiposity in psoriatic patients by dual energy X-ray absorptiometry compared to conventional methods.

Background: Obesity is considered a chronic low-grade inflammatory disease that shares mediators of inflammation with psoriasis, such as TNF-α and IL-6. The relationship between these two conditions involves factors such as predisposition and response to therapy, in addition to an association with cardiovascular disease.

Objectives: The aim of the present study was to investigate the prevalence of adiposity as determined by body mass index (BMI), waist circumference (WC), and dual energy X-ray absorptiometry (DXA) evaluation in patients with psoriasis.

Psoriasis: new comorbidities.

Psoriasis is a chronic inflammatory disease associated with several comorbidities. A few decades ago, it was considered an exclusive skin disease but today it is considered a multisystem disease. It is believed that 73% of psoriasis patients have at least one comorbidity.

Comparative study of the prevalence of sepsis in patients admitted to dermatology and internal medicine wards.

Background: Sepsis is a common cause of morbidity and mortality among hospitalized patients. The prevalence of this condition has increased significantly in different parts of the world. Patients admitted to dermatology wards often have severe loss of skin barrier and use systemic corticosteroids, which favor the development of sepsis.

Case for diagnosis.

Granular cell tumor (Abrikossoff's tumor) is a rare benign disease that preferentially affects the cervicofacial segment. It is usually a solitary nodule that may ulcerate and present pearly infiltration on the borders, while keeping a clean background and a hyperchromic halo. This paper describes the case of an ulcerated granular cell tumor on an unusual location, which reinforces the necessity of including this tumor in the differential diagnosis of nodular-ulcerative skin lesions.

Do you know this syndrome?

Goldenhar syndrome is a sporadic or inherited genetic syndrome characterized by limbal dermoids, preauricular skin tags and mandibular hypoplasia. Vertebral abnormalities may occur. The incidence of this syndrome ranges from 1 in 5,600 to 1 in >20,000 live births.

Rheumatoid nodules: evaluation of the therapeutic response to intralesional fluorouracil and triamcinolone.

Rheumatoid nodules are the most common extra-articular manifestation of rheumatoid arthritis and are present in around 20-25% of patients. Their etiology is unknown and although the nodules may undergo spontaneous remission during the treatment of rheumatoid arthritis, they usually constitute a therapeutic challenge. The present paper describes a case in which the response of rheumatoid nodules was evaluated by ultrasound following infiltration of triamcinolone acetonide and 5-fluorouracil.
