Serious adverse events associated with yellow fever 17DD vaccine in Brazil: a report of two cases.
The yellow fever vaccine is regarded as one of the safest attenuated virus vaccines, with few side-effects or adverse events. We report the occurrence of two fatal cases of haemorrhagic fever associated with yellow fever 17DD substrain vaccine in Brazil. ⋯ These serious and hitherto unknown complications of yellow fever vaccination are extremely rare, but the safety of yellow fever 17DD vaccine needs to be reviewed. Host factors, probably idiosyncratic reactions, might have had a substantial contributed to the unexpected outcome.

Bacteria that adhere to implanted medical devices or damaged tissue can encase themselves in a hydrated matrix of polysaccharide and protein, and form a slimy layer known as a biofilm. Antibiotic resistance of bacteria in the biofilm mode of growth contributes to the chronicity of infections such as those associated with implanted medical devices. ⋯ In biofilms, resistance seems to depend on multicellular strategies. We summarise the features of biofilm infections, review emerging mechanisms of resistance, and discuss potential therapies.

In less-developed countries, opioids such as morphine are often not available for pain relief because of excessive regulations imposed to prevent their misuse and diversion. We describe the effect that these draconian measures have had on the availability of drugs for medical use in Kerala, India, and present results of a study, which we did to ascertain whether or not the misuse and diversion of opioids is as prevalent as the government reaction would suggest. We followed 1723 patients in Calicut, India, who were being treated for pain with oral morphine on an outpatient home-care basis. ⋯ These results suggest that, in the context of India as a less-developed country, oral morphine can be dispensed safely to patients for use at home. We recommend that palliative care programmes talk to concerned governmental authorities, to make them aware of the medical need for opioids, and communicate with local news media to increase awareness of palliative care and the use of these analgesics. Our project has overcome regulatory barriers that had interrupted availability of morphine and its use in pain relief in India.
