- Tungiasis under dermoscopy: in vivo and ex vivo examination of the cutaneous infestation due to Tunga penetrans(2013) CRIADO, Paulo Ricardo; LANDMAN, Gilles; REIS, Vitor Manoel Silva dos; BELDA JUNIOR, WalterThe female flea Tunga penetrans is responsible for a cutaneous parasitosis known as Tungiasis. We report the clinical case of a 12 year-old Caucasian boy who sought treatment in a dermatological private office due to a painful lesion in the plantar area and whose dermoscopic examination, without skin contact, allowed the visualization of parasite's movement inside the skin. The diagnosis of tungiasis is clinical, but it can be aided by in vivo and ex vivo dermoscopic examination of the lesion.
- Evaluation of D-dimer serum levels among patients with chronic urticaria, psoriasis and urticarial vasculitis(2013) CRIADO, Paulo Ricardo; ANTINORI, Lidi Che Leon; MARUTA, Celina Wakisaka; REIS, Vitor Manoel Silva dosBACKGROUND: It has been demonstrated that neutrophils, eosinophils and monocytes, under appropriated stimulus, may express tissue factor and therefore, activate the extrinsic pathway of coagulation. We performed a transversal and case-control study of patients with chronic urticaria and patients with psoriasis, in our outpatient clinic to evaluate the production of D-dimer. OBJECTIVE: To evaluate D-dimer serum levels in patients with chronic urticaria and its possible correlation with disease activity. PATIENTS AND METHODS: The study was conducted from October 2010 until March 2011. We selected 37 consecutive patients from our Allergy Unit and Psoriasis Unit, and divided them into three groups for statistical analysis: (i) 12 patients with active chronic urticaria (CU); (ii) 10 patients with chronic urticaria under remission and (iii) 15 patients with psoriasis (a disease with skin inflammatory infiltrate constituted by neutrophils, lymphocytes and monocytes). Another five patients with urticarial vasculitis were allocated in our study, but not included in statistical analysis. The serum levels of D-dimer were measured by Enzyme Linked Fluorescent Assay (ELFA), and the result units were given in ng/ml FEU. RESULTS: Patients with active chronic urticaria had the highest serum levels of D-dimer (p<0.01), when compared to patients with CU under remission and the control group (patients with psoriasis). CONCLUSIONS: Patients with active chronic urticaria have higher serum levels of D-dimer, when compared to patients with chronic urticaria under remission and patients with psoriasis. We found elevated serum levels of D-dimer among patients with urticarial vasculitis.
- Chronic urticaria in adults: state-of-the-art in the new millennium(2015) CRIADO, Paulo Ricardo; MARUTA, Celina Wakisaka; CRIADO, Roberta Facchini Jardim; REIS, Vitor Manoel Silva dosChronic urticaria has been explored in several investigative aspects in the new millennium, either as to its pathogenesis, its stand as an autoimmune or auto-reactive disease, the correlation with HLA-linked genetic factors, especially with class II or its interrelation with the coagulation and fibrinolysis systems. New second-generation antihistamines, which act as good symptomatic drugs, emerged and were commercialized over the last decade. Old and new drugs that may interfere with the pathophysiology of the disease, such as cyclosporine and omalizumab have been developed and used as treatments. The purpose of this article is to describe the current state of knowledge on aspects of chronic urticaria such as, pathophysiology, diagnosis and the current therapeutic approach proposed in the literature.
