Acute ischemic stroke (AIS) is a time-dependent emergency, since the greatest impact depends on the time elapsed to treatment. The objective of this work was to analyze door to needle (DTN) and start treatment (STT) times and the effect of pre-notification system (PNS) and the appropriate choice of the healthcare center on these variables. An observational study with data obtained from records of patients admitted to the Stroke Unit (SU) was conducted between August 2015 to December 2019.

- Systemic lupus erythematosus (SLE) is linked to neurocognitive dysfunction, particularly affecting fronto-subcortical areas, but there's a lack of research on how this relates to disease activity and damage.
- The study involved 84 SLE patients evaluated using the SLEDAI index for activity, SLICC index for damage, and various neuropsychological tests for cognitive symptoms.
- Findings revealed that higher disease activity was significantly associated with working memory issues, while greater cumulative damage correlated with impairments in visual construction and verbal fluency, indicating complex relationships between SLE and cognitive deficits influenced by different brain mechanisms.
Unlabelled: Sporadic amyotrophic lateral sclerosis (sALS) is considered a multifactorial disease with genetic and environmental factors causing motor neuron degeneration.
Objective: To describe the epidemiological and occupational characteristics of patients with sALS who attended the Ramos Mejía Hospital at Buenos Aires, Argentina.
Method: We analyzed the medical records of sALS patients diagnosed between 2001 and 2008.
We describe a patient who showed cystic lesions in the midbrain and obstructive hydrocephalus. MR imaging features corresponded to abnormal dilatation of perivascular spaces. Similar clinical and MR imaging findings were described in previous reports of patients presenting with mesencephalo-thalamic expanding lacunae; the diagnosis of some of those cases was confirmed at postmortem examination This condition is extremely rare but should be part of a differential diagnosis when evaluating cystic abnormalities in this area of the brain.
