Are there clinical signs and symptoms of infection to indicate the presence of multidrug-resistant bacteria in venous ulcers?

The selection of topical and systemic therapies for the treatment of venous ulcers with signs of infection is challenging and should be accompanied by specific precautionary measures to protect against cross-contamination in the presence of multidrug-resistant microorganisms. However, there are still no clinical indicators for this situation, and confirmation of resistant strains occurs through culture and sensitivity, which can take up to 14 days. During this period, protective measures may no longer be taken, contributing to the spread of these pathogens. This study aimed to analyze the relationship between clinical signs and symptoms of infection in venous ulcers and the presence of antimicrobial-resistant Staphylococcus aureus and/or Pseudomonas spp. A cross-sectional study was developed including 69 patients with 98 venous ulcers. Clinical observation protocol was applied to detect infection indicators established by the European Wound Management Association and microbiological analysis of samples of the lesions. Fisher's exact test and χ2 were used for analyses (P < 0.05). Two indicators of infection predominated (f >70%): discoloration of the opaque type and/or dark brick red and increased exudate volume; 31 (31.6%) ulcer samples showed positive culture for the bacteria studied. There was no relationship between signs and symptoms of infection and the presence of multidrug-resistant microorganisms. Taking into account the percentage of lesions with resistant strains, for safe care, contact precautionary measures should be implemented in the treatment rooms, in addition to standard precautions.

[Occupational accidents with biohazards: the perception of the injured worker]. / Acidentes ocupacionais com material biológico: a percepção do profissional acidentado.

This qualitative research aims at identifying the perception of health care workers of different categories from a specialized institution in emergency health service in the city of Goiânia regarding the context involving biohazard accidents. Firstly, 382 workers were given a questionnaire in order to identify those who had experienced an accident, 39 of which also took part in an interview addressing the general aspects of the accidents. Among the main accident causes to be highlighted are: unattention, non-adherence to preventive measures, patient's severity and hurry. Among the experienced feelings the main ones are: inconfidence, fear of contamination, rage, and even calmness. Half reported no consequence resulted from the accident. Data points to the need of self-worth concerning the worker's health and also of programs aiming at occupational safety enhancement.

[Potentially infectious residues at hemotherapy services and interfaces with infectious diseases]. / Resíduos potencialmente infectantes em serviços de hemoterapia e as interfaces com as doen,cas infecciosas.

The aim was to identify the processing of potentially infectious residues and of piercing and cutting residues at hemotherapy units and their possible relation with workers' health. No service presented a structured plan for managing health service residues or for the occupational safety program. We found an occupational accident rate of 32.82% and that 9.16% of the workers did not have a complete plan of vaccination against hepatitis B. In-service training in handling residues and in occupational health are not standardized. The rate of serum conversion for HBV and HCV after occupational exposure was 11.63%. We concluded that the processing of potentially infectious residues and of piercing and cutting residues at the examined hemotherapy units has exposed workers to the acquisition of infectious diseases.
