T2-weighted imaging hypointensity in an ovarian lesion: is it a benign finding?

ABSTRACT Objective To evaluate whether the presence of a hypointense signal at T2-weighted imaging in a solid ovarian lesion on magnetic resonance imaging is a predictor of stability and benignity. Methods This is a single center study, prospectively read with retrospective acquired data. The database was searched for patients who underwent magnetic resonance imaging between January 2008 and October 2019 and whose reports mentioned solid ovarian lesions with low signal on T2-weighted imaging. A total of 47 nodules were included. A radiologist who was blinded to the clinical indication for magnetic resonance imaging and original reports evaluated the cases. Objective and subjective criteria of ovarian lesions in magnetic resonance imaging were evaluated. Results Thirty-five nodules were considered benign/stable and 12 were considered non-stable. The analysis showed that the non-stable lesions showed statistically more hyperintensity at T1-weighted imaging compared to the stable lesions. Conclusion T2-weighted imaging hypointensity can be considered a predictor of stability in solid ovarian lesions when associated with iso/hypointensity in T1-weighted imaging.

Alterações radiográficas de coluna cervical em artrite reumatoide / Radiographic changes of cervical spine in rheumatoid arthritis

INTRODUÇÃO: O envolvimento da coluna cervical é comum na artrite reumatoide (AR). OBJETIVO: Estudar a prevalência das alterações radiológicas de coluna cervical em pacientes com AR e sua associação com perfil clinico e sorológico da doença. MÉTODOS: Analisaram-se as radiografias de coluna cervical em perfil neutro hiperextensão, hiperflexão e transoral de 80 pacientes com AR para presença de subluxação atlanto-axial (LAA), invaginação basilar (IB) e instabilidade subaxial (ISA). Dados de perfil demográfico, clínico (nódulos, pneumonite intersticial, síndrome Sjögren secundária, uso de medicamentos etc.) e sorológico (FR, anti-CCP e FAN) foram obtidos por revisão de prontuários. RESULTADOS: Havia alguma alteração de eixo de coluna cervical em 26/80 (32,5%); em 12/80 (15%) havia LAA; em 6/80(7,5%) existia IB; em 13/80 (16,2%) existia ISA. Erosões em odontoide foram vistas 16/80 (20,0%). As alterações do eixo cervical estavam associadas com idade de início da doença e duração da mesma (P = 0,03 e 0,02, respectivamente). Não se encontrou associação das alterações em coluna cervical com raça, gênero, nódulos, pneumonite intersticial, Sjögren secundário, FR, FAN ou anti-CCP. Pacientes com alterações do eixo cervical apresentavam mais erosões de odontoide (P = 0,03). CONCLUSÕES: Alterações radiológicas em eixo de coluna cervical são comuns e aparecem mais frequentemente em indivíduos com diagnóstico mais precoce de AR e maior tempo de doença.

INTRODUCTION: The involvement of the cervical spine is a common feature of rheumatoid arthritis (RA). OBJECTIVE: To study the prevalence of radiographic changes of the cervical spine in patients with RA and their association with clinical and serological profiles of the disease. METHODS: We analysed lateral (neutral position, hyperextension, hyperflexion) and transoral views of cervical spine radiographs from 80 individuals with RA to investigate the presence of atlanto-axial subluxation (AAS), basilar invagination (BI), and subaxial instability (SAI). Demographic, clinical (nodules, interstitial pneumonitis, secondary Sjögren's syndrome, medications etc.), and serologic (rheumatoid factor - RF, cyclic citrullinated peptide antibody - anti-CCP, and antinuclear factor - ANF) data were obtained from the clinical records. RESULTS: Cervical spine misalignments were identified in 26/80 (32.5%) participants; AAS occurred in 12/80 (15%) participants, BI in 6/80 (7.5%), and SAI in 13/80 (32.5%). Odontoid erosions were identified in 16/80 (20.0%) participants. Cervical spine misalignment exhibited associations with age at onset and disease duration (P = 0.03 and 0.02, respectively). No associations were identified between the cervical spine changes and the participants' ethnicity or gender, presence of nodules, interstitial pneumonitis, secondary Sjögren's syndrome, RF, ANF, or anti-CCP. The participants with cervical spine misalignment exhibited higher frequencies of odontoid erosion (P = 0.03). CONCLUSIONS: Cervical spine misalignment was a common radiographic finding and occurred more frequently in participants with earlier onset and longer length of RA.

Análise do perfil epidemiológico da mortalidade de 2009 a 2010 de um hospital geral de Curitiba / Epidemiology of hospitalar mortality from 2009 to 2010 in a general hospital in Curitiba

Descrever o perfil dos óbitos ocorridos no hospital, determinar a taxa de mortalidade(TM) hospitalar, determinar a taxa de mortalidade em cada setor de internamento e determinar o índice de letalidade por grupo de doenças do CID-10. Estudo descritivo, retrospectivo através da análise dos prontuários de todos os internamentos ocorridos no Hospital Universitário Evangélico de Curitiba (HUEC) no período de janeiro de 2009 a dezembro de 2010. Ocorreram 64799 internamentos nesse período e, destes, 2499 foram a óbito. As doenças do aparelho circulatório foram as responsáveis pelo maior número de óbitos no HUEC, 21,13% do total. 40,12% dos óbitos ocorridos foram considerados evitáveis. A TM hospitalar foi de 3,92. O grupo de doenças que apresentou a maior taxa de mortalidade foi o de "causas externas de morbidade e mortalidade", com 19,21%. Entre os setores de internamento, as unidades de terapia intensiva (UTI) apresentaram as maiores TM

To describe the profile of the deaths that took place in the hospital, to determine the hospital mortality rate(MR), to determine the mortality rate in each hospitalization sector and to determine the lethality rate per ICD-10 disease group. A descriptive, retrospective research was developed, through the analysis of the medical records of every hospitalization that occurred in the Hospital Universitário Evangélico de Curitiba (HUEC) in the period from January 2009 to December 2010. In this period, there were 64799 hospitalizations, of which 2499 died. Diseases of the circulatory system were responsible for the majority of deaths in the HUEC, 21,13% of the total. 40,12% of the deaths that occurred were considered avoidable. The hospital MR was 3,92%. The group of diseases that presented the highest mortality rate was the "external causes of morbidity and mortality", with 19, 21%. Between the hospitalization sectors, the intensive care unities (ICU) were the ones that showed the highest MR
