An ear canal medication applicator including a tympanogram ear canal occlusion earpiece operatively connected to a bulb insufflator through a body, and a syringe operatively connected to an IV line, wherein the syringe is operatively attached to the body and the IV line is threaded through a portion of the tympanogram ear canal occlusion earpiece. A method of treating the ear canal, by providing a dual application of medication at two different locations in the ear canal of an individual and treating the ear canal.

The current invention is based on the determination that a S1P receptor modulator compound of formula (I):

##STR00001##

decreases the heart rate of a subject to which it is administered by about 5 beats/min or less daily, or about 4 beats/min or less daily, or about 3 beats/min or less daily, or about 2 beats/min or less daily, wherein the S1P receptor modulator is administered at an initial daily dosage which is substantially the same as the standard daily therapeutic dosage.

Certain embodiments described herein provide a method of performing an otological surgical procedure including surgically accessing a middle ear, injecting a perfluorocarbon liquid into the middle ear, and suctioning the isolated blood from the middle ear without removing the perfluorocarbon liquid. The perfluorocarbon liquid is immiscible with blood for isolating blood in the middle ear from the perfluorocarbon liquid. In certain embodiments, the perfluorocarbon liquid has a specific gravity greater than blood to apply positive pressure to surrounding tissues. In certain embodiments, the method includes suctioning the perfluorocarbon liquid from the middle ear after the isolated blood is removed.

A method for treating patients with COVID-19 and/or other respiratory conditions includes administering eighty-five milligrams of dapsone twice daily for twenty-one days. A variety of dapsone formulations and delivery devices are disclosed, including an inhaler, nasal spray, nasal gel, otic formulation, intravenous formulation, oral solution, oral suspension, patch and suppository.

Methods for treating an ear condition in a subject, comprising topically administering to the ear of the subject in need thereof a composition comprising: (i) an anti-infective agent-loaded biodegradable polymer microspheres; and (ii) a thermoresponsive hydrogel.

The disclosure provides polynucleotides containing inner hair cell-specific promoters, as well as vectors containing the same, that can be used to promote expression of a transgene specifically in inner hair cells. The polynucleotides described herein may be operably linked to a transgene, such as a transgene encoding a therapeutic protein, so as to promote inner hair cell-specific expression of the transgene. The polynucleotides described herein may be operably linked to a therapeutic transgene and used for the treatment of subjects having or at risk of developing hearing loss.

Presented herein, in certain aspects, are cell-free therapeutic composition derived from human amniotic fluid (HAF) and uses thereof for the prevention and treatment of selected diseases and disorders.

Ammonia oxidizing microorganism preparations for delivery to the visual and auditory systems, kits including ammonia oxidizing preparations for delivery to the visual and auditory systems, and devices for administering ammonia oxidizing preparations to the visual and auditory systems are provided. Methods of introducing ammonia oxidizing microorganisms to the eye are provided. Methods of introducing ammonia oxidizing microorganisms to the ear are provided. Methods of treating disorders, including eye disorders, ear disorders, and inflammatory disorders, with ammonia oxidizing microorganism preparations are provided.

Disclosed herein are polymer compositions comprising, in some cases, about 15% to about 22% by weight of poloxamer 407, about 1% to about 12% by weight of poloxamer 188, and about 3% to about 15% by weight of PEG 300, wherein the total amount of poloxamer 188 and PEG300 in the composition is about 12% to about 25% by weight. In some cases, polymer compositions disclosed herein can be used for delivery of an active agent to the ear of a subject.

The present invention provides a crude extract, fractions and sub-fractions from the seaweed Fucus distichus (FD), method of preparation and its use for inhibiting the growth of microbial cells, particularly bacteria causing acne or nosocomial infections such as MRSA in humans or MRSP in dogs.
