RESUMO
We present the case of an 18-month-old girl, from rural area, admitted to our clinic for fever and cough. The anamnestic data and the clinical and radiological examinations initially suggested the diagnosis of acute interstitial pneumonia. During hospitalization, she repeatedly presented exacerbations with acute respiratory failure, but without fever. Paraclinic examinations revealed anemia, leukocytosis, inflammatory tests with highly increased values, low values of serum iron and serum calcium, hyperproteinemia with hypergammaglobulinemia, the values of IgE and IgG being highly increased. Repeated pulmonary x-rays-peribronchovascular interstitial thickening, at the level of peri-and right infrahilar area. Medullary puncture-increased percentage of eosinophils in several stages of maturity, approximately 20%, normal values for the other medullary series, without atypical cells; the fingertip hemogram showed anemia, leukocytosis, eosinophilia. The diagnosis turned to a possible toxocariasis-atc anti toxocara canis=55.6 NTU. In the third week of hospitalization, the patient presented short crises of nonfebrile seizures. Normal CT and EEG brain. The child was discharged after 5 weeks, the diagnosis being severe toxocariasis with pulmonary and neurological manifestations; she was recommended an antiparasitary treatment and remained in our clinic's records.
RESUMO
A seven-year-old girl, with erythematous-squamous rash, was admitted to our clinic to decide upon the diagnosis and treatment, being transferred from a county hospital. Heredo-collateral antecedents - an aunt, related to her mother, with psoriasis. When admitted, the patient presented prominent non-pruriginous erythematous plaques, clearly marked and covered by thick, silvery-white scales, easily exfoliating, all over at the level of: scalp, earlobes, neck, torso, limbs, periungual, axillary and genital areas. The dermatological examination: psoriasis vulgaris in patches and plaques, a diagnosis also confirmed histopathologically. Using a local dermatologic treatment, the evolution was favorable, the patient initially presenting thick squamae, then, gradually, there occurred the psoriasis whitening. We presented this case since psoriasis is rarely met at this early age.
RESUMO
INTRODUCTION: The aim of this study is to evaluate the expression of beta-2 adrenergic receptors in the normal peritumoral tissue at the colorectal level, just after the front tumor invasion, in patients with colorectal cancer. METHODS: In this study we analyzed normal peritumoral tissues belonging to 56 patients, who were diagnosed with colorectal adenocarcinoma. These tissues were fixed in paraformaldehyde and paraffinembedded. The immunohistochemical study was done on seriate slides following the hematoxylin and eosin staining, after diagnostic and grading. Correlations were made between beta-2-adrenoreceptors' expression in the normal peritumoral tissue and the clinical and histopathological parameters of the patients with colorectal cancer. RESULTS: There are positive correlations between the expression of beta-2-adrenoreceptors and feminine gender, age group under 50 years, tumor size under 5cm, tumor invasion T3-4 and tumor metastasis in regional lymph nodes N≥2. By analyzing the expression of beta-2-adrenoreceptors in peritumoral tissue depending on tumor grading one can notice that there are positive correlations between beta-2-adrenoreceptors' expression and poorly differentiated colorectal adenocarcinoma. CONCLUSIONS: Positive correlation between this type of receptors in normal glandular epithelium, in the vicinity of tumor invasion front of colorectal neoplasm, and certain clinicopathological features suggests the involvement of tumor microenvironment, which expresses them, in the pathogenesis of this neoplasm.
