Genotypic and Phenotypic Characterization of Replication-Competent HIV-2 Isolated from Controllers and Progressors.

Although some individuals with HIV-2 develop severe immunodeficiency and AIDS-related complications, most may never progress to AIDS. Replication-competent HIV-2 isolated from asymptomatic long-term non-progressors (controllers) have lower replication rates than viruses from individuals who progress to AIDS (progressors). To investigate potential retroviral factors that correlate with disease progression in HIV-2, we sequenced the near full-length genomes of replication-competent viruses previously outgrown from controllers and progressors and used phylogeny to seek genotypic correlates of disease progression.

X-linked cerebral adrenoleukodystrophy.

A man in his 30s presented with a 6-month history of progressive left face, arm and leg weakness. Medical history included epilepsy and vitamin B deficiency. Three maternal second degree relatives died before the age of 7 from various neurological disorders.

Case report: Dueling etiologies: Longitudinally extensive spinal cord lesion mimicking spinal cord infarct with simultaneous positive Lyme serology and amphiphysin antibody.

Background: Longitudinally extensive spinal cord lesions are challenging diagnostic entities as they are uncommon, but various etiologies can cause them.

Case Report: We report a case of a 55-year-old man with a past medical history of hypertension. He is an ex-smoker.

Outcomes of implementation of the FilmArray meningoencephalitis panel in a tertiary hospital between 2017 and 2020.

Background: Acute meningoencephalitis is encountered commonly in the acute hospital setting and is associated with significant morbidity and mortality, in addition to significant healthcare costs. Multiplex PCR panels now allow syndromic testing for central nervous system infection. The BioFire® FilmArray® Meningoencephalitis (ME) allows testing of 14 target pathogens using only 0.

Late-onset ornithine transcarbamylase deficiency mimicking a focal opercular syndrome.

A previously healthy 27-year-old man was brought to hospital after been found late at night confused, agitated and talking incoherently. He represented 12 days later with focal seizures, progressing to anarthria and encephalopathy. MR scan of brain showed diffuse cerebral oedema and his plasma ammonia was >2000 µmol/L (12-55 µmol/L).
