RESUMO
Segmental testicular infarction is an uncommon condition; it is idiopathic in most cases and the pathophysiology behind it is unclear. Patients usually present with a sudden onset of testicular pain, which mimics conditions such as testicular torsion and epididymo-orchitis in clinical presentation and can sometimes be mistaken for a testicular tumor on ultrasound, which can mislead some urologists to opt for an unnecessary surgical treatment. However, with proper assessment and reassuring tests, surgical treatment can be avoided, and successful conservative management can be achieved.
RESUMO
Objectives. Lean construction techniques have been considered an effective approach and strategy to reduce accidents in construction projects. This article aims to investigate the application of the lean construction principle and its impact on occupational health and safety. Methods. To achieve the aim, an analytical descriptive method was used. The data were collected through a questionnaire, with 70 respondents who were chosen using a random stratified sample method. The questionnaire evaluated the perception of contractors and consultants about the important lean construction factors and their impact on construction project safety. Results. There is an agreement that the application of lean construction techniques can be impeded by challenges like lack of lean construction knowledge, complexity, misconception about lean construction and difficulties in changing employees. Conclusions. The study identified strategies that could be used to address these challenges that will improve the safety of construction projects. These include enlightenment on benefits of the lean practice, publication of improvements realized from lean practice, training, workers' involvement and empowerment, persistence, robust planning and gradual implementation.
