This work describes the knowledge and experience of dentists about cardiopulmonary resuscitation (CPR). A total of 182 dentists from São Paulo State, Brazil were interviewed: 59% judged themselves able to define CPR, although only 46% had a correct concept; 54% believed himself to be able to perform CPR, however, none of them referred to have received practical training in CPR; 3% of the interviewed professionals mentioned the occurrence of cadiopulmonary arrest in their dental office. It was concluded that dental surgeons in Brazil should be better trained for medical emergencies that can occur in the dental office.

BACKGROUND AND OBJECTIVES: Advanced cancer usually causes pain, the intensity of which depends on site, level of evolution and type of treatment. This study aimed at evaluating pain in cancer patients who are or have been treated with chemotherapy in a hospital from the city of Imperatriz/MA. METHOD: Data were collected through questionnaires with identification, pre-existing diseases, clinical manifestations, numerical pain evaluation scale and McGill questionnaire. RESULTS: It has been observed that breast cancer (50%) and lung cancer (38.8%) were the most prevalent, respectively, among females and males. Pain was reported by 58.6% of patients during the interview or during the interview's week and most frequently reported sites were upper and lower limbs (18.5%) and chest (11.1%). Mean pain intensity evaluated by the numerical scale was 6.7 ± 1.83, which may be considered moderate pain and sensory pain by McGill questionnaire. CONCLUSION: Moderate and sensory pain was present in most cancer patients and has led to loss of energy to perform daily activities.

The aim of this study was to investigate the effects of exercise in multiple organs of rats treated with doxorubicin. Male adult Wistar rats were distributed into the following groups: sedentary + NaCl; exercise + NaCl; sedentary + doxorubicin; and exercise + doxorubicin. Animals were sacrificed 2 days following injections. Central fragments from heart, liver, and kidney were collected and minced in 0.9% NaCl being cellular suspensions used for the single-cell gel (comet) assay. The results showed that exercise was able to prevent genotoxicity induced by doxorubicin in heart cells. By contrast, exercise was not able to prevent genotoxicity induced by doxorubicin in liver cells. The same occurred to kidney cells, i.e. no statistically significant differences (p > 0.05) were found when compared with groups not exposed to doxorubicin. Taken together, our results support the idea that exercise could contribute to the protective effect against genotoxicity induced by doxorubicin in heart cells.

Taken together, such results demonstrate that metabolic alterations induced by the enzymatic deficiency characteristic of MPS associated with ERT therapy can induce genotoxicity and mutagenicity in peripheral blood and buccal mucosa cells, respectively. This effect appears to be more pronounced to MPS II.
