High Index Of Suspicion

Congenital diaphragmatic hernia (CDH) is a major malformation found in newborns and babies but rarely in adults. CDH is defined by the presence of a defect in the diaphragm, which permits the herniation of abdominal contents into the thorax. The diagnosis of CDH is based on clinical history, examinations and is confirmed by plain X-ray films and computed tomography scans. Here we report a case which was misdiagnosed at another centre as pleural effusion and managed by placement of intercostal tube drainage and later on diagnosed to be case of Morgnani-Larrey parasternal diaphragmatic hernia. Congenital diaphragmatic hernia (CDH) is a major malformation found in newborns and babies but rarely in adults. CDH is defined by the presence of a defect in the diaphragm, which permits the herniation of abdominal contents into the thorax. The diagnosis of CDH is based on clinical history, examinations and is confirmed by plain X-ray films and computed tomography scans. The purpose of reporting this case is to provide information on late-presenting CDH and to emphasize that a high index of suspicion is required for diagnosis and to avoid unwanted complications.

Abstract Objective Ventilation of the middle ear and mastoid air cells is believed to play an important role in the pathogenesis of chronic ear disease. Traditionally, ventilation is assessed by computed tomography. However, this exposes patients to cumulative radiation injury. In cases with a perforation in the tympanic membrane, tympanometry potentially presents a non-invasive alternative to measure the ventilated middle-ear and mastoid air cell volume. This study hypothesised that total tympanometry volume correlates with ventilated middle-ear and mastoid air cell volume. Method Total tympanometry volume was compared with ventilated middle-ear and mastoid air cell volume on computed tomography scans in 20 tympanic membrane perforations. Results There was a high correlation between tympanometry and computed tomography volumes (r = 0.78; p < 0.001). A tympanometry volume more than 2 ml predicted good ventilation on computed tomography. Conclusion These results may help reduce the need for pre-operative computed tomography in uncomplicated cases with tympanic membrane perforations.
