Managing Thyroid Nodules in Qatar During the COVID19 Pandemic

Background: The Coronavirus disease 2019 (COVID-19) pandemic impacted health care systems in all countries, including Qatar. Hamad Medical Corporation (HMC);In compliance with recommendations, suspended all non-urgent procedures, including thyroid fine needle aspiration biopsies (FNAB). Thyroid nodules are second most common cause of referral to HMC endocrine clinic. FNABs are gold standard to differentiate benign from malignant nodules.1- 2

Euglycemic Diabetic Ketoacidosis in a Patient With Gestational Diabetes Mellitus and COVID-19 Infection

Introduction: Diabetic ketoacidosis (DKA) is a life-threatening medical emergency requiring urgent treatment. Euglycemic DKA may occur in patients with both type 1 and type 2 Diabetes Mellitus (DM), as well as pregnancy. The absence of marked hyperglycemia can result in delayed diagnosis and treatment, resulting in potential adverse outcomes. Diabetes is a major comorbidity associated with severe hospital course and high fatality rate among patients with COVID-19 infection. We report our experience in a patient with gestational diabetes mellitus who developed euglycemic DKA and COVID-19 infection in her third trimester of pregnancy. Clinical Case: A 30-year-old lady at 29weeks gestation presented with two-day history of vomiting, diarrhea and abdominal pain. She reported good fetal movements. She had been diagnosed with Gestational Diabetes Mellitus (GDM) at 20 weeks gestational age, receiving treatment with multiple daily injections of insulin. 5 days earlier, she had tested positive for COVID-19 infection. She was asymptomatic;testing was performed as she had been in contact with a confirmed case. On examination she was afebrile and vitally stable, but dehydrated. Her initial laboratory investigations showed ketonemia with normal glucose level and normal anion gap. She was treated as a case of starvation ketosis and dehydration, with intravenous fluids and electrolyte replacement. However, 3 days later, the patient complained of worsening nausea and vomiting with dry cough and she developed hypotension. Chest X-ray showed bilateral mid and lower

Corticosteroids Replacement in a Patient With Panhypopituitarism and COVID-19 Infection

Background: Hypopituitarism refers to complete or partial insufficiency of pituitary hormone secretion and patients require lifelong hormone replacement. Those with ACTH deficiency rely on exogenous glucocorticoids and at times of intercurrent illness require stress doses to prevent an adrenal crisis. The benefits and adverse effects of corticosteroids for treatment of COVID-19 pneumonia are currently under investigation. We report our experience in a patient with COVID-19 pneumonia who received high dose corticosteroids for panhypopituitarism. Clinical Case: A 51-year-old man presented with one-week history of fever and generalized weakness. He had been diagnosed with a non-functional pituitary macro-adenoma causing panhypopituitarism 1 year ago when he developed generalized tonic-clonic seizures. He underwent trans-sphenoidal resection of the pituitary adenoma. However, he then discontinued his hormonal therapy and was lost to follow up. He had postural hypotension but was not tachypneic or hypoxemic. He tested positive for COVID-19 and chest x-ray showed prominent bilateral broncho-vascular markings;he was hospitalized as mild COVID-19 pneumonia. Laboratory investigations revealed secondary adrenal insufficiency, secondary hypothyroidism and hypogonadotropic hypogonadism. MRI of the pituitary now showed persistence of the pituitary macroadenoma, measuring 3.5 x 3.7 x 2.4 cm in dimensions, causing sellar obliteration and left cavernous sinus invasion. Treatment with stress dose steroids, Hydrocortisone 50 mg 4 times daily was initiated, followed by thyroid hormone replacement with Levothyroxine 125 mcg daily. He also received antivirals and

Case Report: Paralytic Ileus: A Potential Extrapulmonary Manifestation of Severe COVID-19.

The COVID-19 pandemic has recently spread worldwide, presenting primarily in the form of pneumonia or other respiratory disease. In addition, gastrointestinal manifestations have increasingly been reported as one of the extrapulmonary features of the virus. We report two cases of SARS-CoV-2 infection complicated by paralytic ileus. The first patient was a 33-year-old man who was hospitalized with severe COVID-19 pneumonia requiring ventilator support and intensive care. He developed large bowel dilatation and perforation of the mid-transverse colon, and underwent laparotomy and colonic resection. Histopathology of the resected bowel specimen showed acute inflammation, necrosis, and hemorrhage, supporting a role for COVID-19-induced micro-thrombosis leading to perforation. The second patient was a 33-year-old man who had severe COVID-19 pneumonia, renal failure, and acute pancreatitis. His hospital course was complicated with paralytic ileus, and he improved with conservative management. Both cases were observed to have elevated liver transaminases, which is consistent with other studies. Several authors have postulated that the angiotensin-converting enzyme 2 receptors, the host receptors for COVID-19, that are present on enterocytes in both the small and large bowel might mediate viral entry and resultant inflammation. This is a potential mechanism of paralytic ileus in cases of severe COVID-19 infection. Recognizing paralytic ileus as a possible complication necessitates timely diagnosis and management.
