Case Reports[Cervical lung hernia in a case of severe chronic asthma and bronchitis].
A case of a bilateral pulmonary hernia of the lungs into the supraclavicular fossae is described. A man, aged 79, with severe chronic asthma and chronic bronchitis due to air pollution, complained of a cervical mass off and on for several years. ⋯ Radiologically this herniation could best be identified on lateral cervical roentgenogram. It is said that cervical lung hernia is a rare condition, but in our experience supraclavicular herniation of the lung is not unusual in cases of severe chronic obstructive lung disease.

[Oxyhemoglobin dissociation curve and 2,3-diphosphoglycerate in chronic hypoxemia].
The measurement of the oxyhemoglobin dissociation curve (ODC) and 2,3-diphosphoglycerate (2,3-DPG) in patients with chronic hypoxemia is important from the view point of tissue oxygenation. However, there have been no consistent results that explain the relation among chronic hypoxemia, 2,3-DPG and P50, which is oxygen pressure at an oxygen saturation of 50 percent. ⋯ In conclusion, P50 and 2,3-DPG are affected largely by Hb concentration or blood pH, with or without hypoxemia. However there is a mechanism by which P50 and 2,3-DPG are increased by hypoxemia itself in a group with normal levels of Hb, pH and PaCO2.
