Beta-blockers
Many of the common symptoms of hyperthyroidism such as palpitations, trembling, and anxiety are mediated by increases in beta-adrenergic receptors on cell surfaces. Beta blockers, typically used to treat high blood pressure, are a class of drugs that offset this effect, reducing rapid pulse associated with the sensation of palpitations, and decreasing tremor and anxiety. Thus, a person with hyperthyroidism can often obtain immediate temporary relief until the hyperthyroidism can be characterized with the Radioiodine test noted above and more permanent treatment take place. Note that these drugs do not treat hyperthyroidism or any of its long-term effects if left untreated, but, rather, they treat or reduce only symptoms of the condition.Some minimal effect on thyroid hormone production however also comes with propranolol—which has two roles in the treatment of hyperthyroidism, determined by the different isomers of propranolol. L-propranolol causes beta-blockade, thus treating the symptoms associated with hyperthyroidism such as tremor, palpitations, anxiety, and heat intolerance. D-propranolol inhibits thyroxine deiodinase, thereby blocking the conversion of T4 to T3, providing some though minimal therapeutic effect. Other beta-blockers are used to treat only the symptoms associated with hyperthyroidism. Propranolol in the UK, and metoprolol in the US, are most frequently used to augment treatment for people with hyperthyroid .
Rud syndrome is a poorly characterized disorder, probably of X-linked recessive inheritance, named after Einar Rud who described 2 patients with the case in 1927 and 1929. It was argued that all reported cases of Rud syndrome are genetically heterogeneous and significantly differ from the original case reports of Rud and that the designation Rud syndrome should be eliminated and that the patients with such diagnosis should be reassigned to other syndromes, such as Refsum disease and Sjögren-Larsson syndrome. Some consider Rud syndrome and Sjögren-Larsson syndrome the same entity and that Rud syndrome does not exist. Presentation
While inclusion criteria for Rud syndrome have varied considerably, the major manifestations include congenital ichthyosis, hypogonadism, small stature, mental retardation, and epilepsy. : 502 : 564  Ocular findings were inconsistently reported and included strabismus, blepharoptosis, blepharospasm, glaucoma, cataract, nystagmus, and retinitis pigmentosa. Other systemic includes metabolic, bony, neurologic, and muscular abnormalities. Diagnosis

Eponym
In 1929, the Danish physician Einar Rud described a 22-year-old Danish male had ichthyosis, hypogonadism, short stature, epilepsy, anemia, and polyneuritis. In 1929, he described a 29-year-old female with ichthyosis, hypogonadism, partial gigantism, and diabetes mellitus. References
