Tietze syndrome

Palpation of the costochondral junction elicits tenderness. There seldom is swelling. It must be differentiated from Tietze syndrome, which is similar in symptomatology. However, Tietze syndrome is generally more localized and swelling is usually present. Costochondritis must also be differentiated from somatic dysfunction, another cause of anterior chest wall pain. Evaluation of rib motion will usually allow a diagnosis however, motion may be restricted in the presence of costochondritis as well.

When ammonia is found in biological materials at physiological pH (7.2), most of it (99%) will be found as ammonium ion, due to its pK of 9.2. This is an important consideration for any subsequent analysis. The determination of ammonia (as dissolved NH3 and ammonium ion) in blood, plasma, or semm is of value in detecting existing or impending hepatic coma and Reyes Syndrome (Meyerhoff and Robins 1980 Tietz 1970). The determination of ammonia in urine had historically been used as an indicator of the kidney s ability to produce ammonia however, this procedure has been replaced by more modem and accurate tests for kidney function. Procedures for the determination of ammonia in biological samples are found in Table 7-1. Ammonia is also tested for in calculi (abnormal concretions in the body formed of mineral deposits, often found in the gall bladder, kidney, or bladder) (Tietz 1970) however, this is not a quantitative test and is not included in Table 7-1.
