Abstract: celiac disease (cd/ nontropicalsprue, gluten-sensitive enteropathy) is a malabsortive condition in which an allergic reaction to the cereal grain-protein gluten (present in wheat, rye and barley) causes small intestine mucosal injury. the onset is in the first four decades of life, with a female to male ratio of 2:1. it may be associated with a wide spectrum of neurological manifestations including cerebellar ataxia, epileptic seizures, dementia, neuropathy, myopathy and multifocal leucoencephalopathy. we report three patients with neurological manifestations related with cd: one with cerebellar ataxia, one with epilepsy and one with cognitive impairment. the diagnosis of cd was confirmed by serologic tests (antiendomysial and antigliadin antibodies) and biopsy of the small intestine. in two patients the neurological symptoms preceded the gastrointestinal abnormalities and in all of them gluten restriction failed to improve the neurological disability. conclusion: cd should be ruled out in the differential diagnosis of neurological dysfunction of unknown cause, including ataxia, epilepsy and dementia. a gluten free diet, the mainstay of treatment, failed to improve the neurological disability.

Abstract: we correlated the anatomopathological abnormalities of the pleural space with the ultrasound findings in patients with pleural effusion and/or parapneumonic empyema and proposed a classification based on these results. ultrasonography is a reliable method to infer the anatomopathological phase of pleural disease and consequently may be of help in the choice of the most suitable treatment.

Abstract: bone marrow trephine biopsies are an integral part of the diagnosis, staging and follow-up of patients with haematologic disorders. lymphoid nodules are a common finding, usually reported in association with chronic inflammatory syndromes, infection haemolysis, myeloproliferative disorders and autoimmune diseases. they are usually considered to be a reactional feature. as bone marrow is the most common site of extranodal involvement of follicular lymphoma, the most important differential diagnosis is represented by bone marrow involvement by malignant lymphoma. from a practical point of view bone marrow lymphoid infiltrates are easy to diagnose on a histological basis. benign aggregates are typically smaller, well distinguishable, contain a mixed population of cells and are nonparatrabecular. neoplastic aggregates involving bone marrow as a paratrabecular infiltrate composed of cleaved cells. immunophenotyping using a panel of monoclonal antibodies is capable of determining the lineage, subset and stage of differentiation of neoplastic lymphoid cells and may therefore contribute to confirm diagnosis. especially in controversial cases, immunogenotypic analysis of the lymphoid proliferation may be helpful. monoclonality may be detected by monotypic expressions of immunoglobulins or clonal rearrangements in the immunoglobulin heavy chain or t cell receptor genes. ideally, the results of immunogenotypic analysis should be interpreted only in conjunction with the results of morphologic evaluation and immunophenotypic analysis. morphology is still the gold standard in evaluating bone marrow infiltration by follicular lymphoma and immunophenotypic and immunogenotypic analysis should be considered as useful complementary investigations.
Distribui??o das les?es esquistossomóticas extra-hepáticas em camundongos infectados pelas linhagens BH e SJ do Schistosoma mansoni

Abstract: context: the association between psoriasis and hypoparathyroidism has been reported by several authors, and it has been suggested that abnormalities in calcium homeostasis may be involved in the development or exacerbation of psoriasis. however, so far there have only been two reports of pseudohypoparathyroidism associated with psoriasis. objective: to describe the familial occurrence of this association for the first time. case reports: two siblings with psoriasis associated with pseudohypoparathyroidism were presented. the first patient was a 24-year-old white male with disseminated erythrodermic pustular psoriasis that began 2 months before admission. he had had a history of mental retardation, recurrent otitis, seizures and arthralgia from the age of 11 years onwards. he presented the characteristic phenotype of albright osteodystrophy: short stature, obesity, round facies, broad forehead, short neck and brachydactylia. he adopted a position of flexed limbs and showed proximal muscle weakness and a positive trousseau sign. he had clinical signs of hypocalcemia (0.69 mmol/l ionized calcium and 3.2 mg/dl total calcium), hyperphosphatemia (6.6 mg/dl), hypomagnesemia (1.0 meq/l), hypoalbuminemia (3.1 g/dl), normal serum intact pth levels (45.1 pg/ml), primary hypothyroidism (13.2 mu/ml tsh, and 4.7 mg/dl total t4), hypergonadotrophic hypogonadism (116.0 ng/ml lh, 13.2 mu/ml fsh and 325.0 ng/dl testosterone), osteoporosis, and diffuse calcifications in soft tissues and in the central nervous system. the second case was a 14-year-old white girl with a history of psoriasis vulgaris from the age of five years onwards, and antecedents of mental retardation. she presented signs of albright osteodystrophy (short stature, round facies, obesity, short neck, brachydactylia), hypocalcemia (ionized calcium of 1.08 mmol/l and total calcium of 6.7 mg/dl) hyperphosphatemia (9.4 mg/dl), elevated serum pth levels (223.0 pg/ml), osteoporosis, and hypergonadotrophic hypogonadism (7.0
Nódulos linfóides medulares

Revista Brasileira de Hematologia e Hemoterapia , 2003,
Abstract: A biópsia de medula óssea é parte integrante do estadiamento e seguimento de pacientes com doen as hematológicas. Nódulos linfóides s o um achado comum, usualmente observados em associa o com doen as inflamatórias cr nicas, infec o, hemólise, síndromes mieloproliferativas e doen as auto-imunes. S o, em geral, considerados reacionais. Sendo a medula óssea o sítio extranodal mais comumente envolvido nos linfomas foliculares, o diagnóstico diferencial mais importante é a infiltra o medular por doen a linfoproliferativa. Do ponto de vista prático, os infiltrados linfóides s o, em geral, facilmente distinguíveis ao estudo histológico. Agregados reacionais s o pequenos, têm bordas delimitadas, s o compostos por uma popula o celular heterogênea e têm localiza o central. Nódulos malignos infiltram a medula óssea na regi o paratrabecular e s o compostos por células clivadas. A análise imunofenotípica, utilizando um painel de anticorpos monoclonais, é capaz de definir a linhagem celular, subpopula o e estágio de diferencia o da popula o neoplásica, contribuindo para a confirma o do diagnóstico. Nos casos controversos, a análise molecular da prolifera o linfóide pode ser útil. A monoclonalidade pode ser demonstrada pela restri o de cadeias leves ou através do rearranjo do DNA da cadeia pesada das imunoglobulinas. Idealmente, os resultados da análise molecular devem ser interpretados em conjunto com a análise morfológica e imunofenotípica. A morfologia continua sendo o padr o-ouro na avalia o da infiltra o medular por linfoma folicular e as análises imunofenotípica e molecular devem ser consideradas complementares.
