Infectious Myelopathies

This article reviews bacterial, viral, fungal, and parasitic pathogens associated with myelopathy. Infectious myelopathies may be due to direct infection or parainfectious autoimmune-mediated mechanisms; this article focuses primarily on the former. RECENT FINDINGS Some microorganisms exhibit neurotropism for the spinal cord (eg, enteroviruses such as poliovirus and flaviviruses such as West Nile virus), while others are more protean in neurologic manifestations (eg, herpesviruses such as varicella-zoster virus), and others are only rarely reported to cause myelopathy (eg, certain fungal and parasitic infections). Individuals who are immunocompromised are at increased risk of disseminated infection to the central nervous system. Within the last few years, an enterovirus D68 outbreak has been associated with cases of acute flaccid paralysis in children, and emerging Zika virus infection has been concurrent with cases of acute flaccid paralysis due to Guillain-Barré syndrome, although cases of myelitis have also been reported. Associated pathogens differ by geographic distribution, with myelopathies related to Borrelia burgdorferi (Lyme disease) and West Nile virus more commonly seen in the United States and parasitic infections encountered more often in Latin America, Southeast Asia, and Africa. Characteristic CSF and MRI patterns have been identified with many of these infections. SUMMARY A myriad of pathogens are associated with infectious myelopathies. Host fac...

More than 6 million Americans live with disabilities following a stroke. Even mild strokes can leave survivors with arm and leg weakness, poor muscle control and memory lapses that worsen with age. Now UCLA neuroscientists have found that patients born without a gene called CCR5 recover better from mild stroke than patients with the gene. The team partnered with Israeli researchers to study the missing gene ’s effect on brain function.Published Feb. 21 in the journal Cell,  the findings could lead to the first pill to reverse the physical and mental aftermath of mild stroke.“This is the first time tha...

ConclusionsOccupational health procedures were enhanced, staff were screened, and antibiotic therapy was provided to GAS-positive staff and patients. The definitive source of infection could not be identified, although staff–patient transmission was the most likely route. The pattern of clonal GAS transmission over the four-year study period suggests that long-term persistence of GAS may have occurred.

This study reports anti-arthritic potential of opuntioside-I opuntiol, and its gold and silver nanoparticles (NPs) against Complete Freund’s Adjuvant (CFA)-induced arthritic rats. The mechanistic studies were performed targeting TLRs (TLR-2 and TLR-4) and cytokines (IL-1β and TNF-α) expressions to validate their anti-inflammatory and immuno-modulatory response.The nano-formulations were successfully characterized employing Atomic Force Microscopy (AFM) and Dynamic Light Scattering (DLS) analysis. Opuntiol and opuntioside (OP and OPG: 10, 50 and 100 mg/kg) and opuntiol-coated silver and gold NPs (OP-...

ConclusionWe have shown a prevalence of 11.8% for AIC among our CLL patients. AIC was associated with unsatisfactory normalization of the hematological parameters even with therapy and lower number of patients with CLL downstaging in comparison with patients without AIC. These results suggest that AIC is a fingerprint of a biologically more aggressive disease even if no significant impact on overall survival was found.
