Brown-Séquard syndrome is characterized by loss of motor function (i.e. hemiparaplegia), loss of vibration sense and fine touch, loss of proprioception (position sense), loss of two-point discrimination, and signs of weakness on the ipsilateral (same side) of the spinal injury. This is a result of a lesion affecting the dorsal column-medial ...
Euthyroid sick syndrome. Euthyroid sick syndrome ( ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional. This condition may result from allostatic responses of hypothalamus-pituitary-thyroid feedback control ...
In the absence of Graves' ophthalmopathy, patients may demonstrate other ophthalmic symptoms and signs due to hyperthyroidism: Dry eyes (due to loss of corneal moisture). [24] A sense of irritation, discomfort, or pain in the eyes. A tingling sensation behind the eyes or the feeling of grit or sand in the eyes.
Fig. 4. A 45-year-old male patient presented with anterior mediastinal metastatic PTC lesions and occult primary on imaging. Histopathology examination of the resected thyroid gland revealed micro-foci of PTC; the largest, in the isthmus, measured 4 mm. a transverse greyscale ultrasound of the thyroid demonstrates homogeneous gland with normal echogenicity and size.
Hashimoto's encephalopathy, also known as steroid-responsive encephalopathy associated with autoimmune thyroiditis ( SREAT ), is a neurological condition characterized by encephalopathy, thyroid autoimmunity, and good clinical response to corticosteroids. It is associated with Hashimoto's thyroiditis, and was first described in 1966.
Thyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine ( T3) and thyroxine ( T4 ). They are tyrosine -based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [2] A deficiency of iodine leads to decreased production ...
LOINC. 82368-2. Thyroid's secretory capacity ( GT, also referred to as thyroid's incretory capacity, maximum thyroid hormone output, T4 output or, if calculated from serum levels of thyrotropin and thyroxine, as SPINA-GT [a]) is the maximum stimulated amount of thyroxine that the thyroid can produce in a given time-unit (e.g. one second).
A syrinx results when a watery, protective substance known as cerebrospinal fluid, that normally flows around the spinal cord and brain, transporting nutrients and waste products, collects in a small area of the spinal cord and forms a pseudocyst . A number of medical conditions can cause an obstruction in the normal flow of cerebrospinal fluid ...
