Bilateral Neonatal Adrenal Hemorrhage Associated With Severe Maternal COVID-19 Infection.

Adrenal hemorrhage is the most common cause of adrenal mass in newborns. We present a case of a full-term male, born by cesarean section due to acute fetal distress from a mother with severe coronavirus disease 2019 (COVID-19) infection. He was diagnosed with hypoxic-ischemic encephalopathy, multifactorial shock, and early neonatal sepsis. On the seventh day of hospitalization, hemoglobin dropped and thus blood transfusion was required, and abdominal ultrasound showed bilateral adrenal hemorrhage. He developed relative adrenal insufficiency without either hemodynamic instability or electrolyte imbalances. The use of parenteral corticosteroids was not required. Follow-up ultrasonography and adrenal axis laboratory examination revealed complete resolution of adrenal hemorrhage. Neonatal adrenal hemorrhage has a wide variety of clinical manifestations. Ultrasound is preferred for both initial screening and follow-up evaluation. Adrenal insufficiency occurs rarely in neonatal adrenal hemorrhage. Treatment is usually conservative. We emphasize the importance of a timely diagnosis and clinical follow-up of adrenal hemorrhage in neonates with fetal distress born from mothers with severe COVID-19.

New-onset thyrotoxicosis in a patient with anaplastic thyroid carcinoma: a diagnostic challenge.

SUMMARY: Anaplastic thyroid cancer (ATC) is the type of thyroid cancer that has the worst prognosis. It usually presents as a rapidly growing cervical mass that generates compressive symptoms. Its association with thyrotoxicosis is rare. A 76-year-old woman, with no contributory history, presented with a 3-month course of fast-growing cervical tumor, associated with tenderness, cough, and weight loss. Physical examination revealed goiter, localized erythema, and a painful and stone tumor dependent on the right thyroid lobe. Due to the malignant findings of the thyroid ultrasound, the patient underwent a thyroid core needle biopsy, which indicated ATC. Laboratory tests revealed leukocytosis, decreased thyroid-stimulating hormone, elevated free thyroxine (fT4), and increased thyroperoxidase (TPO) antibodies. At the beginning, we considered that the etiology of thyrotoxicosis was secondary to subacute thyroiditis (SAT) after SARS-CoV-2 infection, due to the immunochromatography result and chest tomography findings. The result of markedly elevated TPO antibodies left this etiology more remote. Therefore, we suspected Graves' disease as an etiology; however, thyroid histopathology and ultrasound did not show compatible findings. Therefore, we suspect that the main etiology of thyrotoxicosis in the patient was the destruction of the thyroid follicles caused by a rapid invasion of malignant cells, which is responsible for the consequent release of preformed thyroid hormone. ATC is a rare endocrine neoplasm with high mortality; it may be associated with thyrotoxicosis, whose etiology can be varied; therefore, differential diagnosis is important for proper management. LEARNING POINTS: Anaplastic thyroid cancer is the thyroid cancer with the worst prognosis and the highest mortality. The association of anaplastic thyroid cancer with thyrotoxicosis is rare, and a differential diagnosis is necessary to provide adequate treatment. Due to the current pandemic, in patients with thyrotoxicosis, it is important to rule out SARS-CoV-2 as an etiology. Anaplastic thyroid cancer, due to its aggressive behavior and rapid growth, can destroy thyroid follicular cells, generating preformed thyroid hormone release, being responsible for thyrotoxicosis.

Confluence of obesity and MAFLD during Covid-19 pandemic in a developing country.

The direct relation between the overweight/obesity, MAFLD and the severity SARS-CoV-2 infection. increase number of cases of obesity and MAFLD is an important risk factor for high mortality of COVID-19 patients.
