Study Notes
Diabetes Mellitus
- New-onset diabetes mellitus patients may present with polyuria, polydipsia, weight loss, and fatigue.
- Type 1 diabetes mellitus initial presentation may include diabetic ketoacidosis.
- Key symptoms of diabetes mellitus do not include hypertension.
Thyroid Disorders
- A diagnosis of Graves' disease can be confirmed by the presence of exophthalmos or dermopathy.
- Fine-needle aspiration cytology (FNAC) is the most useful initial investigation for a patient presenting with a palpable thyroid nodule who has normal thyroid function tests.
- Bromocriptine is commonly used to treat hyperprolactinaemia.
- High TSH concentration is associated with primary hypothyroidism.
Endocrine Tests
- The water deprivation test is used to confirm a suspected diagnosis of diabetes insipidus.
- Tumours compressing the pituitary stalk are associated with hypopituitarism.
Hypertension
- Hyperaldosteronism and a suppressed renin are associated with Conn's syndrome.
- Adrenalectomy may be needed for patients with Cushing syndrome.
- Following adrenalectomy, patients will need life-long replacement therapy with glucocorticoids and mineralocorticoids, but not androgens.
Complications of Diabetes
- Omitting insulin treatment during a chest infection increases the risk of developing diabetic ketoacidosis or hyperosmolar hyperglycemic state.
- Haemoglobin A1c (HbA1c) test provides information about average glycaemic control.
Vitamin D
- Vitamin D can be acquired through dietary sources, sunlight exposure, and supplements.
- Vitamin D acts to regulate calcium concentrations in the gut, bones, and kidneys, but not in the lungs.
Surgical Complications
- Subtotal thyroidectomy operation for Graves' disease can lead to hypocalcaemia, which may present with a tingling sensation in the fingers and around her lips, with muscle cramps.
- Calcium gluconate is needed to treat hypocalcaemia, and it should be administered intravenously.
- The parathyroid gland may be damaged during subtotal thyroidectomy.
Cushing Syndrome
- Elevated cortisol levels in the blood confirm the diagnosis of Cushing syndrome.
- ACTH levels can indicate whether the patient's Cushing syndrome is arising from dysfunction at the adrenal gland or at the pituitary.
- Adrenal insufficiency can occur when abruptly stopping glucocorticoid treatment.
Metabolic Syndrome
- Patients with metabolic syndrome are at increased risk of developing cardiovascular disease and type 2 diabetes mellitus.
- Orlistat is a licensed drug for the treatment of obesity, and its mechanism of action is by inhibiting pancreatic lipase.
Imaging Modalities
- Ultrasound is the imaging modality used regularly in clinical practice that enables dynamic real-time imaging of internal structures.
- Computed tomography (CT) scanning is associated with exposure to ionizing radiation.
- The image below is a sagittal section of a magnetic resonance imaging (MRI) scan.
