sepsis, myocardial infarction and other causes of shock) thyroid function is tuned down to result in low-T3 syndrome and, occasionally, also low TSH concentrations, low-T4 syndrome and impaired plasma protein binding of thyroid hormones. This endocrine pattern is referred to as euthyroid sick syndrome (ESS), non-thyroidal illness syndrome (NTIS) or thyroid allostasis in critical illness, tumours, uraemia and starvation (TACITUS). Although NTIS is associated with significantly worse prognosis, it is also assumed to represent a beneficial adaptation (type 1 allostasis). In cases, where critical illness is accompanied by thyrotoxicosis, this comorbidity prevents the down-regulation of thyroid function. Therefore, the consumption of energy, oxygen and glutathione remains high, which leads to further increased mortality.These new theories imply that thyroid storm results from an interaction of thyrotoxicosis with the specific response of the organism to an oversupply of thyroid hormones. Diagnosis
The diagnosis of thyroid storm is based on the presence of signs and symptoms consistent with severe hyperthyroidism. Multiple approaches have been proposed to calculate the probability of thyroid storm based on clinical criteria, however, none have been universally adopted by clinicians. For instance, Burch and Wartofsky published the Burch-Wartofsky point scale (BWPS) in 1993, assigning a numerical value based on the presence of specific signs and symptoms organized within the following categories: temperature, cardiovascular dysfunction (including heart rate and presence of atrial fibrillation or congestive heart failure), central nervous system (CNS) dysfunction, gastrointestinal or liver dysfunction and presence of a precipitating event.
Linear focal elastosis or elastotic striae is a skin condition that presents with asymptomatic, palpable or atrophic, yellow lines of the middle and lower back, thighs, arms and breasts. See also
