Tympanitis

Toxic Reactions of the Skin Irritation is the most common reaction of the skin. Skin irritation is usually a local inflammatory reaction. The most common skin irritants are solvents dehydrating, oxidizing, or reducing compounds and cosmetic compounds. Acids and alkalies are common irritants. Irritation reactions can be divided into acute irritation and corrosion. Necrosis of the surface of the skin is typical for corrosion. Acids and alkalies also cause chemical burns. Phenols, organotin compounds, hydrogen fluoride, and yellow phosphorus may cause serious burns. Phenol also causes local anesthesia, in fact it has been used as a local anesthetic in minor ear operations such as puncture of the tympanous membrane in cases of otitis. ...

A 15-month-old girl presents to the pediatric clinic with 2 days of fever (38.9°C), runny nose, and fussiness. Her mother states that she is more irritable than usual and cries many times throughout the night. She is not as interested in eating today. She attends day care and has a 5-year-old brother who recently had a cold. Physical examination reveals erythema and bulging of the right tympanic membrane and the presence of middle ear fluid. The left tympanic membrane is obscured with cerumen.

Single-dose oral toxicity studies in rats, mice, and cattle indicate that signs of diisopropyl methylphosphonate intoxication include decreased activity, ataxia, tympanitis, and prostration within 1-4 hours after dosing (Hart 1976 Palmer et al. 1979). Mink that received 1,852 mg/kg/day diisopropyl methylphosphonate in their feed displayed aggressive behavior. However, it was concluded that this behavior was probably due to hunger resulting from the unpalatability of the feed (Aulerich et al. 1979).

In clinical settings core temperature measurements, including pulmonary artery and esophagus measurements, are often required. In 1959 Benzinger [1] first proposed the human tympanic membrane as the ideal site for core temperature measurements. The tympanic membrane is ideal, because it is located near the carotid artery and shares its blood supply with the hypothalamus, which controls body temperature. First temperature measurements in the ear were performed with thermistor sensors in direct contact with the tympanic membrane. The invasiveness of this method limited its use mainly to anaesthetized patients. 

The first clinical IRET used thermopile sensors to achieve non-contact temperature measurement in the ear. In 1991 a tympanic thermometer for home use was first introduced to the consumer market (Thermoscan HM 1). It utilized a pyroelectric sensor which requires the use of a suitable mechanical shutter or chopper mechanism, since it is only sensitive to temperature changes [3]. The main advantage of the pyroelectric sensor unit was its lower cost. However, prices for thermo-... 

The measurement target, tympanic membrane with surrounding tissue, can be treated as a blackbody radiation source with an emissivity of e(A) 0.98... 1. The emissivity is mainly independent of skin color, cemmen or hair in the ear canal. 

Ten-day courses are recommended for children older than age 2 years and in recurrent otitis AI-AIII media, or otitis media with perforated tympanic membrane. 

Direct application of phenol to the inner ear of rats has resulted in external otitis, inner ear damage, and decreased brain-stem auditory response (Schmidt et al. 1990), and inflammation of the tympanic membrane (Schmidt and Hellstrom 1993). These studies were conducted because phenol has been used as a topical anesthetic in infected ears.

Thermal emission is based on measuring the fundamental absorption bands of glucose at 10pm, using the body s naturally emitted infrared radiation as the source. The detection equipment is similar to that used for infrared absorption spectroscopy. Malchoff et al.82 reported the evaluation of a prototype that measures the infrared emission from the tympanic membrane.
