Listeria monocytogenes is a Gram-positive aerobic bacterium; found ubiquitously in nature; which mainly affects newborns, older adults, immunosuppressed patients and pregnant women. However, Listeria disease can occur in the healthy population. Invasive listeriosis has three dominant clinical forms, bacteremia, neurolisteriosis and maternal-neonatal infection. ⋯ Systemic listeriosis without dominant neurological symptoms is a rare event. Two cases are presented. The first was spondylodiscitis in a normal host and the second was Listeria bacteremia in a febrile immunocompromised patient.

Observational Study
[Incidence of metastasis and survival in patients with primary uveal melanoma].
Primary uveal melanoma is the most common intraocular malignancy in adults. Almost 50% of patients die from metastatic disease despite successful local treatment. The objective was to estimate the incidence of metastasis and survival in patients with primary uveal melanoma. The second objective was to determine the independent predictors of metastasis. ⋯ Although the median time to the event (metastasis) is 26.5 moths, it could occur many years after local oncological effective treatment. An early diagnosis would allow finding smaller tumors and would improve the prognosis.

Little evidence exists on the impact of the COVID-19 pandemics on the compliance with cervical cancer treatment. ⋯ Low access to brachytherapy was a major determinant of non-compliance. irrespective of the effect of the pandemics.

Case Reports
[Subacute ataxia associated with cerebellar ataxia, neuropathy and vestibular areflexia (CANVAS)].
Cerebellar ataxia, neuropathy, and vestibular areflexia syndrome (CANVAS) is a late onset neurodegenerative disorder. Its genetic basis has recently been identified in the gene encoding a subunit of the Replication Factor C (RFC1). We present the case of a 62-year-old woman who experienced a history of a biphasic presentation of imbalance and gait disorders, with rapid onset of symptoms followed by slow and progressive neurological deterioration. ⋯ Subsequently, vestibular function tests identified severe bilateral vestibulopathy. This led to considering CANVAS among the diagnoses, which was ultimately confirmed through genetic testing (biallelic expansion of the pentanucleotide AAGGG in the RFC1 gene). This case highlights the importance of this new described genetic disease and its subacute presentation variant, emphasizing the relevance of objective vestibular function tests in idiopathic ataxias to achieve proper diagnosis and eventual genetic counseling for offspring.

Sarcopenia is a global health problem, there are currently several criteria for its diagnosis and the implementation of its own cut-off values for each population is recommended. The objective was to evaluate the handgrip strength (HG) in postmenopausal women from Buenos Aires and establish a cut-off value. ⋯ The HG is a simple tool that is easy to implement in clinical practice and is considered the first step for the diagnosis of sarcopenia. The cut-off value of HG <17.5 kg could be used for the evaluation of sarcopenia in women >50 years of Buenos Aires.
