Weiss ring: a large, ring shaped floater that is sometimes seen if the vitreous body releases from the back of the eye. When this occurs there is a characteristic pattern of symptoms: Flashes of light ; A sudden dramatic increase in the number of floaters; A ring of floaters or hairs just to the temporal side of the central vision
Oxazolidine is a five-membered heterocycle ringwith the formula (CH 2) 3 (NH)O.The O atom and NH groups are not mutually bonded, in contrast to isoxazolidine. [ 2 ] [ 3 ] Oxazolidines (emphasis on plural) are derivatives of the parent oxazolidine owing to the presence of substituents on carbon and/or nitrogen.
2‑oxazoline, 3‑oxazoline, and 4‑oxazoline (from left to right) Three structural isomers of oxazoline are possible depending on the location of the double bond, however only 2‑oxazolines are common. 4‑Oxazolines are formed as intermediates during the production of certain azomethine ylides [2] but are otherwise rare. 3‑Oxazolines are even less common but have been synthesised ...
Vaginal rings may lead to increased normal vaginal secretions, decreased body weight, reduced symptoms of PMS, and occasionally cases of vaginitis, device-related problems and leukorrhea. [4] [7] [8] Because they release estrogen, vaginal rings have an increased risk of heart attack, stroke, and other serious side effects. [6]
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
Perianal cellulitis, also known as perianitis or perianal streptococcal dermatitis, is a bacterial infection affecting the lower layers of the skin around the anus. [1] [2] [3] It presents as bright redness in the skin and can be accompanied by pain, difficulty defecating, itching, and bleeding.
Primary treatment is prompted by the administration of adequate doses of either the thyroid hormone L-thyroxine given intravenously or by giving liothyronine via a nasogastric tube. It is essential to identify and treat the condition precipitating the coma. [9] Myxedema coma is rare but often fatal.
