We report three patients with appendicitis in whom the diagnosis was difficult to establish. Ultrasonography helped in the management of these patients. To the best of our knowledge, this is the first report of the detection of appendicolith by ultrasonography.

A retrospective study of 140 babies who survived the first week of life and who had endotracheal intubation showed that 65 of them had either or both of the following complications of endotracheal tube therapy: (a) Collapse of one or more lobes with the tube in place or within the first two days following extubation and lasting less than 24 hours. When collapse lasted more than 48 hours, it often required repeated intubation for tracheal cleansing. ⋯ A statistical comparison with intubated babies of similar age without complications showed the following factors to predispose to lobar collapse: younger gestational age, maximal high oxygen concentration administered, and prolonged duration of intubation. The results of endotracheal tube cultures bore no relation to the complication rate.

Isotope studies have related chronic headache after myelography to persistent leakage of normal cerebrospinal fluid (CSF) through an unsealed puncture hole in the dura and arachnoid. Although a technique well known to anesthesiologists, the use of an epidural blood patch (EBP) as a means to seal the dural opening is not known to many radiologists. We have used this technique successfully in three patients and believe it should be performed on all those still suffering from typical postural headaches three weeks after myelography if conservative treatment has failed and if there are no contraindications.

The clinical and radiologic diagnosis of exogenous lipoid pneumonitis often goes unrecognized. A specific history of lipoid aspiration is rarely obtained unless specifically sought. ⋯ Lipid aspiration results in a predictable pathologic and consequently radiologic pattern of disease, often simulating bronchogenic carcinoma. Transthoracic percutaneous fine-needle aspiration biopsy is useful as a complementary procedure to bronchoscopy in making the diagnosis.
