1. Low frequency of hypersensitivity reactions to abacavir in HIV infected patients in a referral center in Bahia, Brazil
Abstract Abacavir can cause a multi-systemic hypersensitivity reaction (HSR) in 5-8% of the patients, which is related to HLA-B*57-01 allele. In Brazil, the HLA-B*57-01 screening test became available only in March 2018, several years after abacavir was in use. In this retrospective study we reviewed medical charts of all patients receiving an abacavir-conta

2. Familial pulmonary fibrosis: a heterogeneous spectrum of presentations
RESUMO Objetivo: Descrever as características clínicas, funcionais e radiológicas de um grupo de casos índice diagnosticados com fibrose pulmonar familiar (FPF) no Brasil. Métodos: Trinta e cinco pacientes com FPF (18 mulheres; 51,4%), com mediana de idade de 66,0 anos (variação: 35,5-89,3 anos), responderam a um questionário padronizado e foram su

3. Imaging in idiopathic pulmonary fibrosis: diagnosis and mimics
Idiopathic pulmonary fibrosis is a chronic disease of unknown etiology that usually has a progressive course and is commonly associated with a poor prognosis. The main symptoms of idiopathic pulmonary fibrosis, including progressive dyspnea and dry cough, are often nonspecific. Chest high-resolution computed tomography is the primary modality used in the ini

4. Reactions related to asparaginase infusion in a 10-year retrospective cohort
Abstract Introduction: Although it is an essential component of the treatment of acute lymphoid leukemia in children, asparaginase causes adverse reactions that sometimes make it impossible to use it fully. Hypersensitivity reactions are the most frequent and may lead to early discontinuation of treatment. The present study aimed to investigate suspicions o

5. Do immunoglobulin G and immunoglobulin E anti-l-asparaginase antibodies have distinct implications in children with acute lymphoblastic leukemia? A cross-sectional study
Abstract Background l-Asparaginase is essential in the treatment of childhood acute lymphoblastic leukemia. If immunoglobulin G anti-l-asparaginase antibodies develop, they can lead to faster plasma clearance and reduced efficiency as well as to hypersensitivity reactions, in which immunoglobulin E can also participate. This study investigated the presence

6. Correlation of serum IgE levels and clinical manifestations in patients with actinic prurigo
Abstract BACKGROUND: Actinic prurigo is an idiopathic photodermatosis, the pathophysiology of which has been hypothesized to involve subtype IV type b (Th2) hypersensitive response, whereby IL4, IL5, and IL13 are secreted and mediate the production of B cells, IgE, and IgG4. OBJECTIVES: To examine the association of serum IgE levels and the clinical severi

7. Acute generalized exanthematous pustulosis x Von Zumbusch’s pustular psoriasis: A diagnostic challenge in a psoriatic patient
AbstractSevere cutaneous drug reactions include a wide spectrum of clinical manifestations ranging from mild morbilliform cutaneous rash, to severe forms of hypersensitivity. Special attention is given in this report to the acute generalized exanthematous pustulosis (AGEP), induced in 90% of cases by the use of systemic drugs, especially aminopenicillins and

8. Dermatosis neglecta
AbstractDermatosis neglecta is the name of a skin condition characterized by papules and polygonal plaques, which are sometimes warty, brownish and hyperpigmented, adherent and symmetric, though removable with ethyl or isopropyl alcohol. It occurs due to inadequate skin cleansing causing accumulation of sebum, sweat, keratin and impurities. Its occurrence, t

9. Dermatitis herpetiformis: pathophysiology, clinical presentation, diagnosis and treatment
Researches on DH have shown that it is not just a bullous skin disease, but a cutaneous-intestinal disorder caused by hypersensitivity to gluten. Exposure to gluten is the starting point of an inflammatory cascade capable of forming autoantibodies that are brought to the skin, where they are deposited, culminating in the formation of skin lesions. These lesi

10. Streptococcal acute pharyngitis
Acute pharyngitis/tonsillitis, which is characterized by inflammation of the posterior pharynx and tonsils, is a common disease. Several viruses and bacteria can cause acute pharyngitis; however, Streptococcus pyogenes (also known as Lancefield group A β-hemolytic streptococci) is the only agent that requires an etiologic diagnosis and specific treatment.

11. American tegumentary leishmaniasis: correlations among immunological, histopathological and clinical parameters
BACKGROUND: American tegumentary leishmaniasis has an annual incidence of 1 to 1.5 million cases. In some cases, the patient's immune response can eliminate the parasite, and the lesion spontaneously resolves. However, when this does not occur, patients develop the disseminated form of the disease. OBJECTIVE: To investigate the association between clin

12. Atypical presentation of sporotrichosis: report of three cases
Sporotrichosis occurs after fungal implantation of Sporothrix spp. in the skin, and is the main subcutaneous mycosis in Latin America. Here we describe three atypical cases of the disease. The first case report an extra-cutaneous occurrence of the disease with joint infection; the second one describes a patient with bilateral lymphocutaneous form of sporotri
