Preoperative treatment of thyrotoxicosis with a beta-adrenergic blocking agent

The clinical usefulness of propranolol as the sole drug in the preoperative treatment of thyrotoxicosis has been investigated. The effect of the drug on the serum levels of thyroxine and triiodothyronine has also been studied. Eight consecutive patients were treated. Four of these showed good clinical response to propranolol and both pre- and postoperative periods were uneventful. Two patients also showed a good clinical response but developed accentuated thyrotoxic symptoms in the immediate postoperative period. One patient showed no clinical response to propranolol therapy and in one further patient the treatment was discontinued because of discomfort. All glands were resected without technical difficulty. They were more vascular and friable after this therapy than after pretreatment with antithyroid drugs and thyroxine. The serum levels of thyroxine and triiodothyronine decreased during propranolol treatment. It is concluded that treatment with propranolol as a sole preoperative drug might be used as an alternative only in cases where conventional therapy is not suitable.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
