Case Reports
[Vibrio vulnificus infection of the skin and soft parts. Communication of a case diagnosed in Argentina].
Vibrio vulnificus is one of the most virulent Vibrio species known. It is a bacterium with universal distribution. The first case registered in Uruguay occurred in 2001 and, since then, several infections have occurred per year. ⋯ We present the case of a severe skin and soft tissue infection by V. vulnificus from an open wound in a patient in contact with a marine aquatic environment on the coast of the River Plate, in Uruguay. Isolation of vibrios from wound specimens can cause rapidly progressing tissue damage, particularly V. vulnificus which has a high mortality rate without early and appropriate intervention. In our case, the rapid identification of the microorganism allowed us to support the empirical treatment used, which a good clinical evolution.

Hepatocellular carcinoma is the most common primary liver tumor, with 905 677 diagnosed cases and 830 180 deaths, in 2020 worldwide. In Argentina, it accounts for the 9th cause of death for cancer in men and the 10th in women. Unlike other highly-prevalent tumors, scientific evidence for most therapeutic options is limited mainly to small cohorts and retrospective studies. ⋯ Recurrence-free survival for those patients who underwent a curative treatment was 89%, 76% y 61% at 1, 3 and 5 years. A thorough analysis of etiology, risk factors, incidence, mortality and treatment was made. The study's importance lies in its large sample size, quantity and quality of data, and will most certainly stimulate the development of local studies in hepatocellular carcinoma.

Factitious thyrotoxicosis is characterized by the intentional or accidental intake of excess thyroid hormones or their derivatives. We describe 6 cases of patients who developed thyrotoxicosis and adverse effects by weight-reducing herbal medicines. ⋯ To make the differential diagnosis between intake of thyroxine (T4) or triiodothyronine (T3) or its derivatives, we must request the measurement of T4 and T3. In case of ingestion of T4, T4 and T3 will be elevated, but in case of ingestion of triodothyronine or its derivatives, T4 will be decreased with elevated T3.

COVID-19 pandemic modified learning conditions in health professions' residences. The objective of the research was to explore Argentinian residents' perceptions regarding training conditions during the first year of pandemic. A descriptive, quali-quantitative study was developed through an online, anonymous questionnaire, with 42 items: 17 closed options and 25 Likert scale from 1 to 5; and 2 open questions. ⋯ They perceived as positive aspects the chance to strengthen bonds between residents and closeness with relatives, and negative aspects the effects on health due to stress and social distancing. In conclusion, the general conditions of training were affected. This leads to rethink the teaching and assessment curricular alternatives, as well as interventions related to the well-being of the residents.

Despite standard thromboprophylaxis, venous thrombosis is common in critically ill patients with COVID-19. The objective of this study was to evaluate deep venous thrombosis (DVT) incidence in patients with severe COVID-19 pneumonia with mechanical ventilation requirements under intermediate dose of chemical thromboprophylaxis (1 mg/kg/day of enoxaparin). This was a single-center, descriptive, cross-sectional study of prospectively collected data. ⋯ In 3 cases, DVT was catheter-related (2 in lower limbs and 1 in jugulo-subclavian confluent), 2 died during follow-up due to acute respiratory distress syndrome (ARDS) complications without thrombotic events or major bleeding. All thrombotic events were asymptomatic. In our series of patients with moderate/severe COVID-19 ARDS, DVT incidence was 10.9% under thromboprophylaxis with intermediate dose (1 mg/kg/ day) of enoxaparin.
