Middle-ear infections

Decongestants are used to treat the congestion associated with rhinitis, hay fever, allergic rhinitis, sinusitis, and the common cold. In addition, they are used in adjunctive therapy of middle ear infections to decrease congestion around the eustachian tube Nasal inhalers may relieve ear block and pressure pain during air travel. Many can be administered orally as well as topically, but topical application is more effective than the oral route. 

Another well-established area of mechanical finite-element analysis is in the motion of the structures of the human middle ear (Figure 9.3). Of particular interest are comparisons between the vibration pattern of the eardrum, and the mode of vibration of the middle-ear bones under normal and diseased conditions. Serious middle-ear infections and blows to the head can cause partial or complete detachment of the bones, and can restrict their motion. Draining of the middle ear, to remove these products, is usually achieved by cutting a hole in the eardrum. This invariably results in the formation of scar tissue. Finite-element models of the dynamic motion of the eardrum can help in the determination of the best ways of achieving drainage without affecting significantly the motion of the eardrum. Finite-element models can also be used to optimise prostheses when replacement of the middle-ear bones is necessary. 

Measles, also known as rubeola, is characterized by a rash that is often complicated by diarrhea, middle ear infection, or pneumonia. Encephalitis occurs in 1 of every 1000 reported cases. Individuals who recover from encephalitis usually have permanent brain damage. Death occurs in 1 to 2 of every 1000 reported measles cases.8... 

Pneumococcal Disease In October 2002, the FDA approved the use of Prevnar for immunization of infants and toddlers against otitis media— middle ear infection. Prevnar is a pneumococcal seven-valent conjugate vaccine. It is formulated with a sterile solution of saccharides conjugated to the antigen, Streptococcus pneumoniae. 

PCR amplification has led to more sophisticated and accurate diagnostic techniques regarding diseases. This allows earlier detection of the disease compared to conventional methods, making earlier treatment possible. For example HIV (human immunodeficiency virus) may be detected by searching for the DNA sequence unique to this virus. Amplifying samples and searching for DNA associated with the bacteria responsible for the condition has identified infectious bacterial diseases. Lyme disease, certain stomach ulcers, and middle ear infections have been detected in this manner. 

It is valuable in critically ill patients with impaired host defence Pseudomonas or Proteus infections in burns, urinary tract infections, lung abscesses, osteomyelitis, middle ear infection, septicaemia meningitis caused by gram negative bacilli, peritonitis, in skin and soft tissue infections and postoperative infection. 

The acute onset of signs and symptoms of middle ear infection following cold symptoms of runny nose, nasal congestion, or cough. 

Acute otitis media presents as an acute onset of signs and symptoms of middle ear infection such as otalgia, irritability, and tugging on the ear, following cold symptoms of runny nose, nasal congestion, or cough (Table 107-2).

The first synthetic heterocyclic pharmaceutical seems to be antipyrine. Antipyrine is a pyrazole analgesic and an antipyretic, like aspirin. Ludwig Knorr used Emil Fischer s discoveiy of phenylhy-drazine to synthesize antipyrine, and in 1883, Knorr was granted a patent on the synthesis. In 1885, one year after market introduction, almost 6 metric tons were sold, and in 1899, sales had grown to almost 800 metric tons. More recently, antipyrine has been used in a solution with benzocaine to relieve ear pain and swelling caused by middle ear infections. Knorr s synthesis is shown in Scheme 8.1. Details of the Knorr synthesis are discussed in Chapter 4. 

Preparations intended for the middle ear are aqueous and sterile. They are mostly used in middle ear infections, because in that condition the drops will be unlikely to reach the inner ear.
