Local evidence suggests insufficient access to palliative care (PC) for advanced cancer patients. The objective was to investigate the attitudes and beliefs of Argentinian medical oncologists regarding PC referral of their patients. ⋯ Oncologists report awareness of the potential advantages of PC and have accessible PC services, but rarely refer patients. They mainly use late-referral criteria. Younger and older age are negatively associated with referral. More research is needed to improve the referral rate and timing of cancer patients to PC.

Complex regional pain syndrome (CRPS), also known as Sudeck syndrome, is a chronic painful condition usually affecting the limbs after trauma or surgery. Its presentation is heterogeneous and its physiopathology, diagnosis and treatment remain controversial. The objective of this study was to analyze a group of patients with this rare syndrome, describing in detail the results of the dual energy X-ray absorptiometry (DXA) and the response to bisphosphonate treatment. ⋯ In our cohort, lower limbs CRPS predominantly affects middle aged women. DXA scans are tests used to quantify bone loss and the response to treatment. The use of bisphosphonates is an interesting therapeutic option to improve clinical symptoms in most patients. Future prospective randomized studies will be needed to confirm our results.

Asymptomatic infections with SARS-CoV-2 are associated with viral transmission and have a key role in the propagation of the pandemic. Understanding viral shedding during asymptomatic infections is critical. Unfortunately, data on asymptomatic SARS-CoV-2 infection in children is extremely limited. ⋯ The positive samples from both children were consistent with B.1.1.28.1 lineage (Gamma). In both asymptomatic children, anti-Spike IgG was detected. Asymptomatic children may represent a source of infection that should not be underestimated during this pandemic.

Lower limb peripheral artery disease (PAD) presents high morbidity and mortality. Women represent a small subgroup in different studies, with scarce evidence regarding the prognosis of this gender on PAD. The aim of the present work was to determine the prognostic impact of female gender on lower limb PAD revascularization. ⋯ Women with symptomatic PAD revascularization presented worse prognosis than men in terms of all-cause mortality and re-hospitalizations for chronic limb-threatening ischemia rates. Therefore, it is essential to achieve an adequate control of cardiovascular risk factors, as well as to optimize medical treatment in female patients.

Histoplasmosis is a systemic mycosis of universal distribution, highly endemic in the Americas. It is caused by a dimorphic fungus Histoplasma capsulatum var. capsulatum. It affects both immunocompetent and immunocompromised individuals where progressive and disseminated forms are observed. A very important risk factor is HIV infection/AIDS, with a mortality rate of 20-40% in Latin America. The diagnosis of this mycosis is made by conventional and molecular methods or by antigen and antibody detection. ⋯ The HC-Ag method demonstrated its usefulness in the diagnosis of progressive disseminated histoplasmosis and the combination of methods is a good option to increase sensitivity and decrease the time to reach the diagnosis of certainty. This allows improving the strategy in the management of the disease and decreasing its case-fatality rate.
