  • Stress-Related Growth Scale-Short Form: A Portuguese validation for cancer patients
    Publication . Oliveira, MA; Guerra, MP; Lencastre, L; Castro, S; Moutinho, S; Park, CL
    Abstract background/objective: Cancer can be extremely disruptive, triggering high levels of distress, and at the same time transformative, promoting perceptions of positive life changes and growth. This study aims to analyze the psychometric proprieties of the Stress-Related Growth Scale Short-Form (SRGS-SF) in cancer patients. Method: 209 Cancer patients heterogeneous in disease stage and diagnosis completed: clinical and sociodemographic information, Distress Thermometer, Positive and Negative Affect Schedule, Visual-analogue Scale of Perceived Positive Life Changes, and Stress-Related Growth Scale-Short Form. Results: The analysis of internal structure pointed to an one-dimensional scale, with high reliability (.92) measured through the McDonald`s omega coefficient. Validity was also evidenced through significant correlations with other variables. Conclusions: The Portuguese version of the SRGS-SF seems to present the necessary psychometric proprieties to be considered a valid and reliable short tool, to assess perceptions of growth following cancer and contribute to targeted and integrative psycho-oncological interventions.

  • Strychnine Intoxication: A Case Report
    Publication . Lage, A; Pinho, J; Alves, R; Capela, C; Lourenço, E; Lencastre, L
    Strychnine acts as an inhibitor of post-synaptic neuronal inhibition and intoxication leads to distinct clinical manifestations which may culminate in death. Since its commercialization is prohibited in most countries, cases of strychnine intoxication are now rare. We present a case of an elderly patient who voluntarily ingested a white powder thought to be strychnine. He developed myoclonus, startle response, and episodes of generalized muscle contractions accompanied by respiratory arrest in one occasion. Diazepam, valproic acid and supportive treatments were able to control manifestations, however the patient died after 2 days. Our aim is to alert clinicians that, despite its rarity, strychnine intoxication may still be seen in emergency departments, and clinical outcome can be influenced by rapid recognition and timely institution of adequate treatment.
