Relevance of conventional radiography in indicating maxillary antral lavage.
The conventional radiographs of 84 antra were used to study the relationship of radiographic interpretation with the lavage result. In addition, the interpretations by a clinician and a radiologist were compared, showing that there was no significant difference between the predictive accuracy of either. The only reliable radiographic predictor of lavage result was the presence of normality or a fluid level; opacity and so-called mucosal thickening were deemed unreliable and their validity was questioned.
Developing psychodynamic group treatment methods for aggressive male inpatients.
Group psychotherapy is one intervention that can be used for aggressive male inpatients. This paper reports relevant literature and clinical applications for conducting a psychodynamic psychotherapy group designed to help patients (a) identify, understand, and deal with underlying problems resulting in aggressive behavior; (b) improve interpersonal relationships; and (c) find more appropriate ways of expressing feelings, particularly those associated with aggressive behavior. The review of literature focuses on therapeutic approaches for dealing with aggressive feelings in group therapy; men's issues in group psychotherapy, including stages of group development for men and the expression of aggression; and the outcome of aggressive behavior in response to group therapy. Clinical applications discussed are preparation for the group; the group contract, including the "group as a whole" approach; patient selection; modeling authority; and countertransference and projective identification.

Diffuse leptomeningeal oligodendrogliomatosis: radiologic/pathologic correlation.
We present the radiologic and pathologic findings in a boy who presented with diffuse leptomeningeal enhancement and whose clinical status deteriorated over the course of 5 years. During this period, MR images showed progression of the enhancement in the subarachnoid spaces, formation of intraaxial cysts, and hydrocephalus. Autopsy findings revealed diffuse oligodendroglioma throughout the leptomeninges of the brain and spine, with no definite intraaxial focus. The radiologic and pathologic features of diffuse leptomeningeal oligodendrogliomatosis are reviewed.
Implementing a comprehensive child restraint program in a pediatric hospital: an effective model.
Motor vehicle crashes remain a leading cause of death and injury to young children. Appropriate child safety seats and child safety restraints can provide life-saving protection to children riding in motor vehicles. Many children, however, travel unrestrained or improperly restrained. Consideration of appropriate child safety restraint systems for children is an important aspect of discharge planning and can provide families with the means to prevent unintentional injuries and deaths resulting from motor vehicle crashes.

The assessment of antichymotrypsin in cancer monitoring.
A comparative study of serum antichymotrypsin, acid glycoprotein and antitrypsin levels has been made in various cancers. Antichymotrypsin (ACT) shows a non-specific elevation in metastatic cancer, and the response reflects tumour progression in a similar fashion to the other two acute phase reactant proteins. The main advantage of ACT as a marker appears to be its Normal distribution in health, and lack of phenotypic variation.
Tricuspid valve replacement for cardiogenic shock after acute right ventricular infarction.
A 66-year-old man had an acute inferior wall myocardial infarction complicated by hypotension, high-grade atrioventricular block, and distended neck veins, suggesting associated right ventricular infarction. He failed to respond to volume loading, intra-aortic balloon counterpulsation, and pharmacologic afterload reduction. Cardiac catheterization five days after the infarction disclosed severe tricuspid regurgitation and a hemodynamic pattern resembling pericardial constriction. Emergency tricuspid valve replacement was dramatically successful.
Phospholipid class as a determinant in docosahexaenoic acid's effect on tumor cell viability.
Here we explore how incorporation of the omega-3 fatty acid docosahexaenoic acid (DHA) into murine leukemia cells (T27A) may alter membrane structure and function. When cells were cultured in DHA-supplemented medium, DHA incorporated rapidly and preferentially into phosphatidyl-ethanolamine (PE), with lesser and slower incorporation into phosphatidylcholine (PC). DHA at low concentrations preferred PE over neutral lipids, but in DHA excess accumulation in neutral lipids outstripped that of phospholipids. High DHA levels reduced cell growth in the apparent absence of lipid peroxidation. To study the importance of DHA's phospholipid class, cells were fused with lipid vesicles of either 18:0, 22:6 PE or 18:0, 22:6 PC. DHA-containing PC vesicles produced a dose-dependent decrease in cell viability, whereas PE-containing vesicles had little effect although they appeared more fusogenic. These results provoke the interesting speculation that T27A cells can safely accumulate DHA in PE, but are vulnerable if excessive DHA is incorporated into PC.
