(Bl), a snake endemic to Martinique, is responsible for numerous envenomations annually, leading to severe complications such as thrombosis, necrosis, and hemorrhage. This case series investigates the link between envenomation and acute myocarditis, utilizing cardiac magnetic resonance imaging (MRI) to enhance management strategies. In both cases, cardiac MRI confirmed myocarditis with edema, and subsequent cerebral MRI revealed bilateral infarcts.

- The study investigates a new water-soluble polysaccharide called PSP extracted from leaves, using techniques like FT-IR and NMR to identify its chemical structure.
- HPLC analysis shows that PSP is a heteropolysaccharide made up of two types of monosaccharides, with additional assessments revealing its semi-crystalline nature and various functional properties.
- The research highlights PSP's antioxidant potential in food preservation, particularly in ground beef, where it significantly inhibits lipid oxidation, microbial growth, and demonstrates stability in color, pH, and moisture.
Article Synopsis
- Researchers sequenced the complete genome of a rabies virus from a gold panner's cerebellum who died from unknown encephalitis in French Guiana.
- The analysis revealed that this virus is closely related to rabies strains found in vampire bats.
- This finding marks the second recorded case of human rabies in that region.
Article Synopsis
- The venom of Bothrops lanceolatus, a viper species from Martinique, is known to cause thrombosis, particularly in patients bitten by juvenile snakes, prompting research into the underlying mechanisms.
- The study compared the venoms of juvenile and adult specimens, revealing that juvenile venom induces more significant thrombus formation in mice than adult venom, despite both having similar proteomes.
- An experimental model showcasing the thrombotic effects of B. lanceolatus venom was established, highlighting the differences in effects between juvenile and adult specimens, and indicating that other factors like metalloproteinase activity may not be solely responsible for thrombus formation.
This qualitative review aims to summarize current knowledge on ventriculostomy-related infection (VRI) pathophysiology and its prevention. VRI generally occurs at day 10, mainly because of Gram-positive cocci, after a cerebrospinal fluid leak. Skin microbiota and biofilm seem to play a major role in VRI pathogenesis.
