Background: COVID-19 infection produces various symptoms and affects multiple systems, including the endocrine system. Lesions have been documented at the hypothalamic and pituitary axis, hypothetically explained by the presence of angiotensin II receptors in these structures and by direct immune-mediated viral lesions. These manifest with electrolyte and hormonal alterations. Case report: We present the case of a female patient who, after infection by SARS-CoV-2, presented with hypernatremia refractory to conventional management. Her diagnostic study documented hyposthenuria, high serum osmolarity, and low urinary osmolarity. The condition was corrected with desmopressin, leading to a diagnosis of central diabetes insipidus. A brain MRI revealed a lesion in the pituitary gland, confirming the clinical findings. The only etiological hypothesis for this lesion is its association with SARS...

Background: Ophidic accident is a neglected disease that affects tropical countries. Latin America is the second region after Africa, with the most cases worldwide. Local lesions accompany its clinical course up to systemic affectations such as renal, hematological, and neurological lesions. Cardiac complications are rare, especially in patients who do not have cardiovascular risk factors. There are reports of acute myocardial infarction, but there is little information about heart failure due to Bothrops spp. Case report: We present the case of a 25-year-old man without cardiovascular risk factors who was admitted to the intensive care unit and developed heart failure with cardiogenic shock and multi-organ failure secondary to a snake bite. Conclusions: Although the characteristic clinical course of a bothropic ophidian accident and its systemic manifestations are mainly related to coag...

Pulmonary aspergillosis, caused by the opportunistic fungus Aspergillus, primarily affects immunocompromised individuals. This report presents three cases: An 18-year-old female with acute leukemia developed respiratory distress and bilateral "tree-in-bud" patterns on CT. Despite voriconazole treatment, she succumbed to respiratory failure. A 58-year-old female with diabetes and COPD had dyspnea and hemoptysis. Imaging revealed a cavitated lesion, confirming aspergilloma. Surgery was considered due to active hemoptysis. A 41-year-old female with a history of tuberculosis presented with fever and respiratory symptoms. CT showed cavitated lesions and bronchiectasis, confirming chronic aspergillosis. She responded well to voriconazole. These cases highlight the variability in pulmonary aspergillosis and underscore the importance of timely diagnosis and treatment to improve patient outcomes.
