Introduction: The authors proposed an application study of the Latin Questionnaire, an updated protocol to conduct the anamnestic study of work-related musculoskeletal disorders through closed questions and the introduction of a predetermined severity threshold that allows for epidemiological studies to be conducted, comparing the results of the exposed population with those of a reference population. Background: Similar protocols describing work-related musculoskeletal disorders occurring in the previous 12 months are available in the literature. For many of these, problems arise when the results must be processed collectively., Objectives: Here we present application examples, with comments on the results in terms of statistical significance of the comparison., Methods: The anamnestic study of the Latin Questionnaire is based on symptoms: discomfort, pain, and evaluation of paresthesia. Each symptom is described considering: location, duration, number of episodes, irradiation, and treatment. The model, which covers the previous 12 months, is designed to identify in the spine, upper and lower limbs: positive anamnestic case, case with minor disorders, negative case., Results: The original application examples show the scope of the disorders presented in the groups of workers exposed to known risk, in comparison with those of the reference group: the significance of the differences is estimated statistically., Conclusions: The Latin Questionnaire, also implemented in the digital format (free to download), allows for comparing the data of exposed and unexposed workers and their statistical significance easily and automatically., Competing Interests: Conflicts of interest: No

A diagnosis of cancer is frightening at any age, but especially when the patient is a child. Only what is suspected can be diagnosed, only what is known or at least known to exist is suspected, but musculoskeletal tumors are infrequent and therefore very difficult to diagnose or treat. Probably due to their infrequency, the complexity of the radiological images, histopathological appearance, as well as the serious consequences due to inadequate biopsies and treatments, musculoskeletal tumor pathology requires clinical management that must be carried out by a group of specialists with specific training, allowing an adequate diagnosis, introduction of adjuvant therapies, as well as surgical treatment, making multidisciplinary treatment essential today. Imaging studies provide essential information on the nature of each lesion, its size, its anatomical location, the effect on the surrounding bone or soft tissues and the involvement of adjacent joints and neurovascular structures. In this article the authors will discuss the advances in nuclear medicine techniques (scintigraphy, SPECT/CT and PET/CT) and their usefulness in the staging of pediatric malignant musculoskeletal tumors, as well as in the assessment of response, follow-up, and diagnosis of recurrence., (Copyright © 2022 Sociedad Española de Medicina Nuclear e Imagen Molecular.
