Adrenal

This chapter covers the adrenal gland. It begins with the anatomy and physiology of the adrenal gland, then continues with imaging techniques. It then covers adrenal disorders, including Conn’s syndrome, adrenal Cushing’s syndrome, Adrenal insufficiency, Addison’s disease, and multiple autoimmune disorders. The investigation, treatment, and long-term management of primary insufficiency is covered. Various adrenal tumours and associated disorders, along with their management, are described.

Endocrine surgery

This chapter outlines the clinically relevant anatomy and physiology of the thyroid and parathyroid glands. The assessment and management of a patient with a thyroid goitre and post-operative complications are described in detail. Conditions such as thyrotoxicosis, thyroid malignancies, hyperparathyroidism, adrenal incidentaloma, cushing’s syndrome, conn’s syndrome, phaeochromocytoma and multiple endocrine neoplasia are discussed in this chapter.

Spectrum of adrenal disorders in a referral hospital of Bangladesh

Background: Adrenal diseases are common and their presentations are variable. This study aimed to determine the frequency and presenting features of various adrenal diseases in a tertiary care hospital of Bangladesh. Methods: This retrospective descriptive study was carried out in Endocrinology in-patient department of BIRDEM General Hospital, Dhaka, Bangladesh, from October 2017 to December 2018. During this time, total 745 patients were screened; out of whom 91 had adrenal diseases. Results: Mean age of the study population was 39.6±11.5 years. Among them, 65.9% were male. Most (75.8%) cases had adrenal insufficiency, followed by endogenous Cushing’s syndrome (8.8%), Conn’s syndrome (6.6%), non-functioning adenoma (3.3%), congenital adrenal hyperplasia (CAH) (2.2%), pheochromocytoma (1%), myelolipoma (1%) and adrenal carcinoma (1%). According to functional status, most (75.8%) were hypofunctional. Of the patients with adrenal insufficiency, secondary adrenal insufficiency was the most common (78.3%). Among the secondary adrenal insufficiencies, 75.9% had iatrogenic adrenal insufficiency and 24.1% had pituitary diseases. Regarding the cases of primary adrenal insufficiency, 20% cases were due to adrenal tuberculosis, 6.6% were due to adrenal histoplasmosis and 73.3% were idiopathic. Most of the adrenal insufficiency patients presented with hypotension (66.7%), followed by gastrointestinal symptoms (76.8%), weight loss (55.1%), hyponatraemia (42%), pigmentation (13%) and hypoglycemia (10%). In this study, 9.9% patients had adrenal incidentaloma. Most of them (88.9%) were benign. Causes of Cushing’s syndrome among the study population were, iatrogenic (66.7%), adrenal (16.7%) and pituitary cause (16.7%). In this study, 16.5% patients had endocrine hypertension and the causes were endogenous Cushing’s syndrome (53.3%), Conn’s syndrome (40%) and pheochromocytoma (6.7%). Of the hypertensive patients, 60% had co-existing hypokalemia. Conclusion: Adrenal insufficiency was the most common adrenal disorder followed by endogenous Cushing’s syndrome, Conn’s syndrome, non-functioning adenoma and other adrenal disorders. Presentations of adrenal disorders are variable. Among the cause of adrenal insufficiency iatrogenic adrenal insufficiency was the most common. Birdem Med J 2021; 11(2): 103-107

Quadriplegia and rhabdomyolysis as a presenting feature of Conn’s syndrome

Conn’s syndrome is an important endocrine cause for secondary hypertension. Hypokalaemia paralysis and rhabdomyolysis with accelerated hypertension may be the presenting symptoms of Conn’s syndrome. Here, we present one such case of a 38-year-old woman presenting with accelerated hypertension and acute onset quadriplegia. On biochemical evaluation, she was found to have severe hypokalaemia, metabolic alkalosis and elevated creatinine phosphokinase. Further evaluation revealed an elevated aldosterone renin ratio suggestive of primary hyperaldosteronism which was localised to left adrenal adenoma on contrast-enhanced CT. Patient’s blood pressure and serum potassium levels normalised after resection of the adrenal adenoma.
