Bedaquiline, sold under the brand name Sirturo, is a medication used to treat active tuberculosis. Specifically, it is used to treat multi-drug-resistant tuberculosis (MDR-TB) along with other medications for tuberculosis. It is used by mouth.Common side effects include nausea, joint pains, headaches, and chest pain. Serious side effects include QT prolongation, liver dysfunction, and an increased risk of death. While harm during pregnancy has not been found, it has not been well studied in this population. It is in the diarylquinoline antimycobacterial class of medications. It works by blocking the ability of M. tuberculosis to make adenosine 5-triphosphate (ATP).Bedaquiline was approved for medical use in the United States in 2012. It is on the World Health Organizations List of Essential Medicines. The cost for six months is approximately US$900 in low-income countries, US$3,000 in middle-income countries, and US$30,000 in high-income countries.The public sector invested US$455–747 million in developing bedaquiline. This is thought to be 1.6× to 5.1× what the owner, Janssen Biotech, invested (estimated at US$90–240 million). If capitalized and risk-adjusted, these costs become US$647–1,201 million and US$292–772 million, respectively.
Cheyletiella is a genus of mites that live on the skin surface of dogs, cats, and rabbits.The adult mites are about 0.385 millimeters long, have eight legs with combs instead of claws, and have palpi that end in prominent hooks. They do not burrow into the skin, but live in the keratin level. Their entire 21-day life cycle is on one host. They cannot survive off the host for more than 10 days. Cheyletiellosis
Cheyletiellosis (also known as Cheyletiella dermatitis)," is a mild dermatitis caused by mites of the genus Cheyletiella. It is also known as walking dandruff due to skin scales being carried by the mites. Cheyletiellosis is seen more commonly in areas where fleas are less prevalent, because of the decreased use of flea products that are also efficacious for the treatment of this mite.Cheyletiellosis is highly contagious. Transmission is by direct contact with an affected animal. Presentation
Symptoms in animals vary from no signs to intense itching, scales on the skin, and hair loss. The lesions are usually on the back of the animal. Symptoms in humans include multiple red, itchy bumps on the arms, trunk, and buttocks. Because humans are not a host for the mite, the symptoms usually go away in about three weeks. Though the medical community does not consider a human mite infestation a legitimate diagnosis, it will treat the symptoms if necessary. Diagnosis
Diagnosis is by finding the mites or eggs microscopically in a skin scraping, combing, or on acetate tape applied to the skin.
