[Correlation between the radiologic study of deglutition and the clinical picture in systemic sclerosis (scleroderma)].
Fifty-one patients with systemic sclerosis (scleroderma) were studied by means of videofluoroscopy in order to evaluate the abnormalities in the oropharyngeal and esophageal phases of deglutition and to correlate the radiological patterns with the clinical features of the disease. Thirteen patients (25.5%) exhibited swallowing disorders such as oral leakage, retention, penetration, mild or moderate aspiration and abnormal upper esophageal sphincter behavior. These dysfunctions were more evident in patients with esophageal motility abnormalities. ⋯ This indicates a discrepancy between clinical symptoms and radiological picture of the esophagus. The radiological examination of the oral-pharyngeal and esophageal phases of deglutition is important in patients with scleroderma in order to evaluate visceral involvement, motility disorders, and risk of aspiration. Such radiological information can be useful in preventing esophagitis and pulmonary complications.

[Usefulness of computerized tomography in the prognosis of subarachnoid hemorrhage].
The authors reviewed the computed tomographic (CT) scans of 129 patients with subarachnoid hemorrhage (SAH). The close correlation is stressed between the severity of the symptoms onset and the amount of blood demonstrated on CT scans. ⋯ CT also shows the possible complications (hematoma, hydrocephalus, mass effect) that, when present, have a negative impact on prognosis, independent of the neurologic condition. Finally, the authors point out how a reliable prognosis of SAH is based upon combined clinical evaluation and CT study.

Comparative Study[Quantitative analysis of the lung CT in normal subjects and in patients with noncardiac pulmonary edema].
A quantitative analysis was performed of the CT images relative to 7 normal human subjects and to 22 patients affected with ARF (Acute Respiratory Failure). The CT scanner image quality was investigated, and the unit was checked with quality control procedures, in order to assure reliability and reproducibility. In every patient the lung was scanned at 3 different levels--basis, hilum and apex. ⋯ A method was then tested to evaluate lung weight; the data obtained did not differ from literature data. All the patients were treated with different positive and expiratory pressure (PEEP). For different PEEP values, the quantitative data from CT analysis were correlated with morphofunctional indices.

[Hepatobiliary scintigraphy in the study of neonatal hepatic cholestasis].
Severe neonatal cholestasis is a clinical problem requiring a differential diagnosis of intra- (hepatitis) and extrahepatic (biliary atresia) causes, prognosis and therapy being different in the two cases. Eighteen patients of pediatric age underwent US and hepatobiliary scintigraphy. US findings were aspecific in both hepatitis and biliary atresia. ⋯ In a case of biliary cirrhosis secondary to occlusion, orthotopic liver transplantation was performed whose success was scintigraphically monitored. Our results point to hepatobiliary scintigraphy after phenobarbital as the best noninvasive procedure for both diagnosis and postoperative follow-up of biliary atresia. Labeled bile excretion within 24 hours was rarely found in both atresia and neonatal hepatitis.
