Chest wall metastasis of squamous cell carcinoma of larynx.

Distant metastases in squamous cell carcinoma of head and neck are most often to the lung, liver and bone. They rarely metastasise to chest wall. We report a 60-year-old male patient who initially presented with an abscess over the anterior chest wall that was initially treated for infective pathology. Due to lack of response, cytological examination was performed that turned out to be metastasis from carcinoma larynx.

Evaluation of microbiocidal activity of superoxidized water on hospital isolates.

Background: Prevention of nosocomial infections, pre-operative and post-operative complications is directly linked with effective disinfection and decontamination. Microbial decontamination is the most serious challenge to the today's health care practice despite the abundance of disinfectants and chemicals as there are increasing reports of emergence of resistance to the action of commonly used disinfectants. There is a need to evaluate the efficacy of newer methods of asepsis for better patient management. Aim: This study was designed to evaluate the microbiocidal activity of superoxidized water (SOW) on common clinical isolates, ATCC strains, vegetative cells and spores of Bacillus subtilis. Materials and Methods: Bacterial suspensions were treated with SOW and deionized water (control). All the tubes were incubated at 37°C for 0.5, 2.5 and 5.0 min. The number of viable cells was counted. Results: All the clinical isolates and ATCC strains were killed within 0.5 min of exposure to the SOW. Vegetative cells and spores of B. subtilis were killed after 5.0 min. Conclusion: We conclude that SOW is an effective microbiocidal agent for routine hospital use.
