Blood Cell Count and the Presence or Absence of Infection in Venous Ulcers Treated With Platelet-Rich Plasma.

Introduction: In general, chronic wounds are colonized by bacteria; however, when microorganisms start to multiply at higher levels, wounds can become infected, causing prolongation of the inflammatory phase and retardation of collagen synthesis and epithelialization.

Objective: The objective of this study was to evaluate the presence of infection in venous ulcers after 12 weeks of treatment with autologous platelet-rich plasma (PRP) and determine global white blood cell counts.

Materials And Methods: This case series study involved a sequential sample of 17 patients with venous ulcers treated with PRP for 12 weeks.

Geographic tongue severity index: A new and clinical scoring system.

Objective: This study was designed to develop a severity index for geographic tongue (GT) based on the Psoriasis Area and Severity Index.

Study Design: This cross-sectional observational study, with a retrospective sample of 100 participants, included 5 photographs of each case (dorsum, right border, left border, apex, and lingual belly), totaling 500 images of GT, which were evaluated by 3 experienced researchers in the area of GT and psoriasis. At the end of the analysis, GT was classified as mild, moderate, or severe.

Metabolic syndrome and psoriatic arthritis among patients with psoriasis vulgaris: Quality of life and prevalence.

Interest has increased in comorbidities associated with psoriasis and their effects on health-related quality of life (HRQoL). This study aimed to evaluate the prevalence of metabolic syndrome (MetS) and psoriatic arthritis (PsA) and to investigate HRQoL and the prevalence of hypertension, type 2 diabetes mellitus (T2DM), obesity and dyslipidemia. In a cross-sectional design, patients diagnosed with plaque psoriasis answered an interview and standardized questionnaires (Dermatology Life Quality Index questionnaire [DLQI], 36-Item Short Form Health Survey [SF-36] and EuroQol Five-Dimension Questionnaire Three-Level version [EQ-5D-3L]).

Geographic tongue and fissured tongue in 348 patients with psoriasis: correlation with disease severity.

Geographic tongue (GT) and fissured tongue (FT) are the more frequent oral lesions in patients with psoriasis. The aims of this study were to compare the prevalence of GT/FT between psoriasis group (PG) and healthy controls (HC) and investigate the correlation between GT/FT and psoriasis severity using the PASI and age of psoriasis onset. Three hundred and forty-eight PG and 348 HC were selected.

Application of platelet-rich plasma in the treatment of chronic skin ulcer - case report.

The platelet-rich plasma (PRP) has proved promising regarding its applicability in dermatology, especially in the healing of chronic ulcers. The autologous platelet-rich plasma is obtained by centrifuging the blood, so that the components are separated by density gradient. The final product is a gel rich in growth factors that act in tissue repair by activating fibroblasts and inducing extracellular matrix remodeling.

Oral candidiasis in patients with psoriasis: correlation of oral examination and cytopathological evaluation with psoriasis disease severity and treatment.

Background: Infections are known to trigger and exacerbate psoriasis. Although oral candidiasis is often clinically diagnosed, it is not always confirmed by laboratory tests such as oral cytopathology.

Objectives: The aims of this study were to determine the prevalence of oral candidiasis in patients with psoriasis through clinical and cytopathological diagnosis and to investigate the association between oral candidiasis and psoriasis with regards to the severity of the clinical presentation and the type of treatment for psoriasis.

[Skin diseases in hemodialysis and kidney transplant patients].

Recently, the world is facing an escalate in the incidence of chronic kidney disease (CKD). Databases containing information about patients in end stage renal disease (ESRD), especially in the United States, were the sources of initial information about it. Brazil has the third largest population on dialysis in the world, and there are about 680 dialysis centers, spread across all units of the federation in the present, providing treatment to an estimated population of almost 90,000 patients.

Pseudoxanthoma elasticum.

A 55-year-old man with progressive loss of vision was referred for dermatology consultation for the evaluation of his skin lesions. The cutaneous examination of the patient revealed multiple small yellow papules, coalescing into plaques, on his neck, axillae and periumbilical regions. He also had redundant skin folds on the axillae.

Cat-transmitted cutaneous lymphatic sporothricosis.

Sporotrichosis is the most common of the deep mycoses. In most cases the transmission occurs secondary to recent penetrating trauma with plant thorns, wood splinters or contaminated organic material. We report a case of a 68-year-old Brazilian female with a small ulcer on her right forefinger and palpable erythematous nodules on her right forearm.
