Sonographic characteristics of various chest diseases in 154 cases were analysed according to margin of the lesion, internal echogenecity, posterior echo enhancement, air bronchogram etc. We intended to present the basic sonographic patterns of common chest diseases. The study included 10 normal cases, 10 cases with lung abscesses, 31 cases of pneumonia, 24 cases of tumors, 11 cases of obstructive atelectasis, 8 cases of pleuropericarcadial effusions, 10 cases of minimal effusions, 6 cases with pleural thickening, 32 cases of massive pleural effusion with simple compression atelectasis and 12 cases of pneumonia with parapneumonic effusion. ⋯ The internal echogenecity of lung parenchyma in pneumonia with parapneumonic effusion was similar to that of pneumonia. Obstructive atelectasis, mass, consolidation and encapsulated effusion could be differentiated by chest sonography without much difficulty. Sonography could aid chest radiography by giving more morphologic information and was cheaper than computed tomography.

Maximum inspiratory pressure: a neonatal criterion for weaning from mechanical ventilation.
Thirty-three newborn infants admitted to the neonatal intensive care unit of our hospital were studied. Mechanical ventilation was used for more than 24 hours for each patient. Maximum inspiratory pressure (MIP) was measured by means of a manometer at the oral end of the endotracheal tube just prior to extubation. ⋯ The patients in group I had a significantly lower MIP (P < 0.01) than group II, of the 28 patients in group I, 27 had MIP equal to or exceeding -35 cm H2O and only one case had MIP of -30 cm H2O. We conclude that measurement of MIP is a simple, useful and safe method for neonates to predict successful extubation from prolonged mechanical ventilation. A neonate with a MIP exceeding -35 cm H2O can be safely weaned from mechanical ventilation.
