Metastatic and aggressive renal cell carcinoma mimicking a unilateral choroidal tuberculoma / Carcinoma de células renais metastático grave mimetizando tuberculoma de coroide unilateral

ABSTRACT Ocular metastases from systemic tumors are uncommon. The choroid is the most frequent target, with a preference for elderly individuals. Lung cancer is the predominant primary tumor that metastasizes to the eyes in males, although other ocular conditions such as uveitis and retinal lesions can mimic secondary tumor implants in ocular tissues. On fundoscopy, choroidal metastasis resembles other infectious processes, especially choroidal tuberculoma. Therefore, patients presenting with choroidal masses should undergo detailed clinical examinations, especially if the mass is the first manifestation of a systemic and severe disease. In this report, we describe a young man with a metastatic choroidal tumor secondary to papillary renal cell carcinoma mimicking a unilateral choroidal tuberculoma.

RESUMO A disseminação metastática ocular de tumores sistêmicos é incomum, ocorrendo principalmente na coroide e em pacientes idosos. O câncer de pulmão é considerado o principal tumor metastático ocular em homens, contudo, outras doenças oculares, como as uveítes e lesões retinianas, podem mimetizar os implantes secundários tumorais nos tecidos oculares. O aspecto fundoscópico das neoplasias da coroide pode apresentar similaridade com outros processos infecciosos, especialmente o tuberculoma de coroide. Dessa forma, a investigação clínica detalhada é de grande importância no diagnóstico de pacientes com massas coroideanas, especialmente quando configuram a primeira manifestação de uma doença sistêmica e grave. Relatamos um caso raro de metástase coroideana como primeira manifestação clínica do carcinoma de células renais em um homem jovem, mimetizando um tuberculoma de coroide.

Evaluation of Job-Related Anxiety Symptoms Among Brazilian Social Security Medical Experts.

OBJECTIVES: The function of a medical expert within the scope of the Brazilian social security system consists of medically evaluating the examinee to draw a conclusive opinion on the person's working ability capacity and to characterize the disability for social security and assistance purposes. Forensic decisions inevitably converge on two opposite outcomes: concession or refusal. Rejection is against the interests of the candidates, who can direct their disappointment and dissatisfaction at the professional, exposing the latter to potentially stressful situations. The present study aimed to determine whether the prevalence of stress and anxiety symptoms is higher among social security medical experts than among medical experts in other public service careers. The study was also intended to propose organizational changes aimed at the preservation and recovery of the mental health of medical experts. METHODS: The evaluation was conducted using a specific, previously validated job-related stress questionnaire and a series of questions about subjective perceptions of work performance, labor stressors and emotional status. RESULTS: We found an overwhelming and alarming prevalence of stress and dissatisfaction related to occupational aspects among social security experts, often culminating in emotional exhaustion, a characteristic feature of burnout syndrome. CONCLUSION: There is a high prevalence of job-related stress among social security doctors in Brazil, warranting implementation of specific measures to ensure the adequate provision of social security services to the population, thus avoiding social injustice and financial damage.

[Ophthalmomyiasis as a cause of canalicular lesion]. / Oftalmomiíase como causa de lesão canalicular.

OBJECTIVE: Myiasis is the invasion of human tissues by Diptera larvae. Ocular involvement is uncommon. Trauma is the major cause of lacrimal apparatus lesions. However, it is rarely associated with parasitic infestation. The objective of this paper is to report a case of canalicular laceration caused by Dermatobia hominis larva. DESCRIPTION: An eight-year-old girl presented preseptal cellulitis that was refractive to antibiotics. A Dermatobia hominis larva was observed inside the lacrimal sac. Surgical extraction was performed and laceration of the lacrimal drainage system was noted. COMMENTS: Parasitic infection of the lacrimal apparatus is rare. Surgical extraction is the treatment of choice in such cases. Despite being uncommon, ophthalmomyiasis should be considered as a possible diagnosis when cellulitis is not responsive to antibiotics, especially in endemic areas. This is the first description of lacrimal drainage system injury by Dermatobia hominis larva.

Oftalmomiíase como causa de lesão canalicular / Ophthalmomyiasis as a cause of canalicular lesion

OBJETIVO: Miíase é a invasão de tecido humano pela larva de uma mosca da ordem Díptera. O envolvimento ocular não é comum. Lesões do aparelho lacrimal geralmente estão associadas a traumas e raramente são devidas a infestações parasitárias. O objetivo deste trabalho é relatar um caso de laceração canalicular causado por larva de Dermatobia hominis. DESCRIÇÃO: Criança do sexo feminino, 8 anos de idade, apresentou-se com celulite pré-septal não responsiva a antibioticoterapia. Foi observada uma larva de D. hominis no saco lacrimal. Realizou-se a extração cirúrgica da larva e observou-se lesão do sistema de drenagem lacrimal. COMENTARIOS: A infestação parasitária em via lacrimal é rara. A extração cirúrgica da larva é recomendada como tratamento de escolha. Apesar de incomum, a oftalmomiíase deve ser considerada como um diagnóstico diferencial possível em celulites não responsivas ao tratamento convencional, especialmente em áreas endêmicas. Esta é a primeira descrição de lesão do sistema de drenagem lacrimal por larva de D. hominis.
