Introduction The traditional classification of Pneumonia as either community acquired (CAP) or hospital acquired (HAP) reflects deep differences in the etiology, pathogenesis, approach and prognosis between the two entities. Health-Care Associated Pneumonia (HCAP) develops in a heterogeneous group of patients receiving invasive medical care or surgical procedures in an outpatient setting. For epidemiology and outcomes, HCAP closely resembles HAP and possibly requires an analogous therapeutic regimen effective against multidrug-resistant pathogens. Materials and methods We reviewed the pertinent literature and the guidelines for the diagnosis and management of HCAP to analyze the evidence for the recommended approach. Results Growing evidence seems to confirm the differences in epidemiology and outcome between HCAP and CAP but fails to confirm any real advantage in pursuing an aggressive treatment for all HCAP and CAP patients. Discussion Further investigations are needed to establish the optimal treatment approach according to the different categories of patients and the different illness severities.

The Impact

To categorize the Patient-specific Functional Scale (PSFS) activities in snakebite envenoming (SBE) using the International Classification of Function (ICF) model in order to describe the impact of SBE on patients’ activities and daily lives and to develop a theoretical SBE model of functioning, we performed a post-hoc analysis of two multi-center, prospective studies, conducted at 14 clinical sites in the United States with consecutive SBE patients presenting to the emergency department. Qualitative content analysis and natural language processing were used to categorize activities reported in the PSFS using the ICF model. Our sample included 93 patients. The mean age was 43.0 (SD 17.9) years, most had lower extremity injuries (59%). A total of 99 unique activities representing eight domains came within the Activity and Participation component of the ICF model, with the majority in the Mobility and General Tasks and Demands domains. The main concerns of SBE patients are the ability to perform daily activities and to engage within their social environment. Applying the ICF model to SBE can facilitate the creation of a patient-centered treatment approach, moving beyond body-structural impairments towards a function-based treatment approach and facilitate early integration of rehabilitation services.

Comparative anatomists have of late directed considerable attention to the determination of the relations of the cerebrum and cerebellum. This has been in great measure due to the publication by Professor Owen of a system of classification of the Mammalia founded on their cerebral characters. The statement made by that eminent anatomist, that the posterior, or third, lobe of the cerebrum is peculiar and common to the genus Homo, and that equally peculiar are the “posterior horn of the lateral ventricle” and the “hippo-campus minor,” which characterise the hind lobe, has led to much discussion. Various anatomists have published descriptions and drawings of dissections of the brains of many of the Quadrumana, especially of several of the higher apes.

T Cell Lymphomas

Understanding the pathogenesis and molecular biology of malignant lymphomas is challenging, given the complex nature and incongruity of these disorders. The classification of lymphoma is continually evolving to account for advances in clinical, pathological, molecular biology and cytogenetic aspects, which impact our understanding of these disorders. The latest fourth edition of the WHO classification of lymphoid malignancies was released in 2016 to account for these changes. Additionally, unlike B-cell lymphomas (BCL), T-cell lymphomas (TCL) are uncommon, and may be sporadically experienced in clinical practice. These disorders are rare, thus early diagnosis is challenging for both physicians and radiologists, owing to the overlap in clinical and imaging features with other, more common disorders. We aim to discuss some rare variants of T-cell lymphomas, including clinicopathologic and imaging features, as well as to give a glimpse of the updates contained within the new 2016 WHO classification.

Introdução: O queratocisto odontogênico é por definição um cisto de desenvolvimento que apresenta caráter agressivo afetando o complexo bucomaxilofacial. Tendo em vista que muitas vezes são assintomáticos, o seu diagnóstico normalmente é obtido através de exames radiográficos de rotina. Objetivo: apresentar um caso clínico referente ao diagnóstico e tratamento de um queratocisto odontogênico em região posterior de mandíbula. Caso clínico: Paciente do sexo feminino, normosistemica, feoderma. Observou-se aumento de volume extraoral, lado direito da face em região de ângulo mandibular. Ao exame radiografico periapical, observou-se uma imagem radiolúcida, bem delimitada, unilocular, associada ao dente 47.  Ao exame físico intraoral, observou-se abaulamento ósseo na região do referido dente. Foi então solicitada uma tomografia computadorizada, na qual foi detectada extensa lesão óssea expansiva em ramo mandibular direito. Realizou-se uma punção aspirativa local, detectando presença de conteúdo líquido. Primeiramente foi realizada uma biópsia incisional com instalação de dispositivo descompressivo. O laudo histopatológico foi de cisto odontogênico inflamatório. O dispositivo de descompressão permaneceu por 9 meses, apresentando uma diminuição significativa da lesão. Foi realizada então, a enucleação da lesão remanescente, associado a exodontia dos dentes 47 e 48 e enviado material para histopatológico, que dessa vez, confirmou diagnóstico de queratocisto odontogênico. Ao exame de imagem pós-operatório de 6 meses, observou-se formação óssea completa sem sinais de recidiva. Conclusão: O tratamento proposto se mostrou eficaz no tratamento do queratocisto odontogênico, o acompanhamento com exames de imagem é de extrema importância, tendo em vista a possibilidade de recidiva.

Abstract Background Solid component size on thin-section computed tomography is used for T-staging according to the eighth edition of the Tumor Node Metastasis classification of lung cancer. However, the feasibility of using the solid component to measure clinical T-factor remains controversial. Methods We evaluated the feasibility of measuring the solid component in 859 tumours, which were suspected cases of primary lung cancers, requiring surgical resection regardless of the procedure or clinical stage. After excluding 126 pure ground-glass opacity tumours and 450 solid tumours, 283 part-solid tumours were analysed to determine the frequency of cases where the measurement of the solid portion was difficult along with the associated cause. Pathological invasiveness was also evaluated. Results The solid portion of 10 lesions in 283 part-solid nodules was difficult to measure due to an underlying lung disease (emphysema and pneumonitis). The solid portion of 62 lesions (21.9%) without emphysema and pneumonitis was difficult to measure due to imaging features of the tumours. Among the 62 patients, five had no malignancy and one with a tumour size of 33 mm had nodal metastasis. There were 56 lesions with a tumour size of ≤30 mm, wherein nodal metastases, vascular and/or lymphatic invasions were not observed. Conclusion For one-fifth of the part-solid tumours, measurement of the solid component was difficult. Moreover, these lesions had low invasiveness, especially in T1. The measurement of the solid portion and the classification of T1 in 1-cm increments may be complex.
