RESUMO

Abstract Lymphocytic thrombophilic arteritis is a recently described entity, histopathologically characterized by lymphocytic vasculitis that affects the arterioles of the dermo-hypodermic junction, associated with deposition of fibrin and a luminal fibrin ring. A 49-year-old female patient presented with achromic maculae and a well-defined ulcer on the medial aspect of the left lower limb. The biopsy showed intense inflammatory infiltrate in the papillary dermis with a predominance of lymphocytes, and medium-caliber vessels surrounded by mononuclear infiltrates in the deep reticular dermis. Masson's trichrome staining showed intense destruction of the muscle layer of the vascular wall and a fibrin ring. Good clinical response was attained with azathioprine. The authors believe that the ulceration might be another clinical presentation or represent an atypical progression of this condition.

RESUMO

Abstract Protothecosis is a rare condition caused by the aclorophylated algae of the genus Prototheca. In humans, protothecosis, caused mainly by P. wickerhamii, manifests itself in three forms: cutaneous, articular and systemic. It can occur in both immunocompetent and immunosuppressed individuals, being much more common in the latter. We present a new case of protothecosis in Brazil in a kidney transplant recipient.

RESUMO

ABSTRACT INTRODUCTION: Suppurative labyrinthitis continues to result in significant hearing impairment, despite scientific efforts to improve not only its diagnosis but also its treatment. The definitive diagnosis depends on imaging of the inner ear, but it is usually clinically presumed. OBJECTIVE: To analyze the clinical factors and hearing outcomes in patients with labyrinthitis secondary to middle ear infections and to discuss findings based on imaging test results. METHODS: Retrospective cohort study, based on the charts of patients admitted with middle ear infection-associated labyrinthitis. RESULTS: We identified 14 patients, eight (57%) of whom were females and six (43%) males. Mean age was 40 years. Cholesteatomatous chronic otitis media was diagnosed in six patients (43%), acute suppurative otitis media in six (43%), and chronic otitis media without cholesteatoma was diagnosed in two patients (14%). Besides labyrinthitis, 24 concomitant complications were identified: six cases (25%) of labyrinthine fistula, five cases (21%) of meningitis, five cases (21%) of facial paralysis, five cases (21%) of mastoiditis, two cases (8%) of cerebellar abscess, and one case (4%) of temporal abscess. There was one death. Eight (57%) individuals became deaf, while six (43%) acquired mixed hearing loss. CONCLUSION: Suppurative labyrinthitis was often associated with other complications; MRI played a role in the definitive diagnosis in the acute phase; the hearing sequel of labyrinthitis was significant.


RESUMO INTRODUÇÃO: Labirintite permanece resultando em deficiência auditiva significativa, apesar dos esforços científicos para melhorar não só o diagnóstico, como também o tratamento. O diagnóstico definitivo é dependente de imagens da orelha interna, mas geralmente é presumido clinicamente. OBJETIVO: Analisar os fatores clínicos e os resultados auditivos em pacientes com labirintite secundária à otite média e discutir os achados dos exames de imagem. MÉTODO: Estudo de coorte retrospectivo, com base nos prontuários de pacientes diagnosticados com labirintite associada à infecção da orelha média. RESULTADOS: Foram identificados 14 pacientes, oito (57%) do sexo feminino e seis (43%) masculino. Média etária de 40 anos. Otite média crônica colesteatomatosa foi diagnosticada em seis pacientes (43%), otite média aguda em seis pacientes (43%) e otite média crônica sem colesteatoma em dois pacientes (14%). Foram identificadas 24 complicações concomitantes: seis casos (25%) de fístula labiríntica, cinco casos (21%) de meningite, cinco (21%) de paralisia facial, cinco (21%) de mastoidite, dois casos (8%) de abscesso cerebelar e um caso (4%) de abcesso temporal. Houve uma morte. Oito (57%) indivíduos tornaram-se anacústicos, enquanto seis (43%) evoluíram para perda auditiva mista. CONCLUSÃO: Labirintite foi frequentemente associada a outras complicações; RNM auxiliou no diagnóstico definitivo da labirintite na sua fase aguda; a sequela auditiva da labirintite foi significativa.

RESUMO

UNLABELLED: Urgent and emergency care are common happenings in ENT practice and most carry low morbidity and mortality. There are but few studies that address the epidemiology of these situations. OBJECTIVE: To evaluate the epidemiological characteristics of care in the emergency department of otorhinolaryngology at a high complexity hospital. METHOD: Epidemiological, cross-sectional study, retrospective with data collection carried out from medical records from the emergency department of otorhinolaryngology of a high complexity hospital in São Paulo, for a period of 12 months. DATA COLLECTED: age, gender, clinical diagnosis and management. The cases were divided by subspecialty: otology, rhinology, pharyngolaryngeal-stomatology and head and neck surgery. We evaluated the level of urgency/emergency, etiology and monthly distribution of visits. RESULTS: 17,503 medical records were obtained; 1,863 were excluded. Of the 15,640 cases included, the average age was 36.3 years. 9,818 (62.77%) corresponded to cases considered as emergency/urgency. Among the urgency/emergency cases, 6,422 (65.41%) were diagnosed in the ear and among the 10 most prevalent diagnostics, 7 were in the subspecialty of otology. CONCLUSION: Among the patients seen in the emergency department of otolaryngology evaluated in this study, 62.77% corresponded to cases of urgency/emergency, predominantly in the otology subspecialty.

RESUMO

As urgências/emergências em Otorrinolaringologia são desordens comuns e de baixa morbimortalidade, em sua maioria. Existem poucos estudos que abordam a epidemiologia desses atendimentos. OBJETIVO: Avaliar as características epidemiológicas dos atendimentos em pronto-socorro de Otorrinolaringologia em um hospital de alta complexidade no período de 12 meses. MÉTODO: Estudo epidemiológico, tipo corte transversal, retrospectivo com coleta de dados realizada a partir das fichas de atendimento do pronto-socorro de Otorrinolaringologia de um hospital de alta complexidade do estado de São Paulo, pelo período de 12 meses. Foram levantados os dados: idade, sexo, diagnóstico clínico e conduta. Os atendimentos foram divididos em subespecialidades: otologia, rinologia, faringolaringoestomatologia e cirurgia de cabeça e pescoço. Nível de urgência/emergência, etiologia e distribuição mensal dos atendimentos foram avaliados. RESULTADOS: Obtidas 17.503 fichas de atendimento, foram excluídas 1.863. Das 15.640 fichas incluídas, a média de idade foi 36,3 anos. 9.818 (62,77%) corresponderam a atendimentos considerados como urgência/emergência. Entre os atendimentos urgência/emergência, 6.422 (65,41%) foram por diagnósticos em otologia e entre os 10 diagnósticos mais prevalentes, sete foram da subespecialidade de otologia. CONCLUSÃO: Dentre os atendimentos em pronto-socorro de Otorrinolaringologia avaliados, 62,77% correspondem a casos de urgência/emergência, com predomínio na subespecialidade de otologia.

RESUMO

UNLABELLED: Otitis media (OM) is considered a potentially severe disease due to the risk of complications. OBJECTIVE: To establish the annual incidence of intratemporal complications (ITC) resulting from OM and to prospectively assess patients for epidemiological and clinical factors. METHOD: This prospective cohort study included patients admitted during one year at a university hospital diagnosed with intratemporal complications of OM. Patients were analyzed for age, gender, type of intratemporal complication, treatment, and clinical outcome. The overall incidence of complications and the specific incidence rates of each type of complication were determined. RESULTS: 1,816 patients were diagnosed with OM; 592 (33%) had chronic OM; 1224 (67%) had acute OM. Fifteen patients were diagnosed with OM ITC, adding up to an annual incidence of 0.8%. Nineteen diagnoses of ITC were made in 15 patients. Seven (36.8%) patients were diagnosed with labyrinthine fistula, five (26.3%) with mastoiditis, four (21.1%) with peripheral facial palsy, and three (15.8%) with labyrinthitis. CONCLUSION: The incidence of intratemporal complications remains significant when compared to the rates seen in developed countries. Chronic cholesteatomatous otitis media is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.

RESUMO

Otite média (OM) é considerada doença potencialmente grave em razão dos riscos de complicações que podem ocorrer em sua evolução. OBJETIVO: Estabelecer a incidência anual de complicações intratemporais de OM e avaliar prospectivamente os pacientes por meio da análise dos aspectos epidemiológicos e clínicos. MÉTODO: Estudo de coorte contemporânea. Durante o período de um ano, os pacientes admitidos em um Hospital Universitário, com diagnóstico de OM e de complicação intratemporal (CIT) de OM foram incluídos no estudo. Os dados avaliados foram: idade, sexo, tipo de complicação intratemporal, tratamento e desfecho clínico. A incidência geral das complicações e de cada complicação foi determinada. RESULTADOS: 1.816 pacientes foram diagnosticados com OM. Em 592 (33%) indivíduos, o diagnóstico foi de otite média crônica; em 1224 (67%) o diagnóstico foi de otite média aguda. CIT de OM foi diagnosticada em 15 pacientes, perfazendo uma incidência anual de CIT 0,8%. Foram identificados 19 diagnósticos de CIT em 15 pacientes. Fístula labiríntica foi diagnosticada em sete (36,8%) indivíduos, mastoidite em cinco (26,3%), paralisia facial periférica em quatro (21,1%) e labirintite em três (15,8%). CONCLUSÃO: A incidência das complicações intratemporais permanece significativa quando comparada à de países desenvolvidos. A otite média crônica colesteatomatosa é a etiologia mais frequente das complicações intratemporais. A fístula labiríntica é a complicação intratemporal mais comum.
