BACKGROUND Although much has been published with regard to the columella assessed on the frontal and lateral views, a paucity of literature exists regarding the basal view of the columella. The objective of this study was to evaluate the spectrum of columella deformities and devise a working classification system based on underlying anatomy. METHODS A retrospective study was performed of 100 ...

Background Several treatment options have been described for chronic rhinosinusitis (CRS), yet many patients remain poorly responsive to medical and surgical therapy. Recently, antiIgE monoclonal antibody has emerged as a potential therapy for CRS. However, to date evidence for its efficacy in this patient population is sparse. The purpose of this study is to evaluate the clinical effect of ant...

The Rise in the U.S. Dollar The value of the dollar has climbed steadily over much of the past two years (Chart 1). The dollar’s rise through August 1998 represents more than a 20 percent appreciation over its average value in the 1991-95 period and more than a 30 percent strengthening relative to its unusually weak performance in April 1995. This large appreciation is reminiscent of the apprec...

A prospective study of acute hypoxic respiratory failure was carried out by nine centers in a collaborative NIH study from 1 September 1975 to 1 March 1977. Serious hypoxic respiratory failure was defined in 713 patients by the presence of (1) endotracheal intubation and positive airway pressure for at least 24 hours, and (2) the administration of at least 50 percent oxygen. The 490 patients be...

MAGNITUDE OF COAL PRODUCTION Coal accounts for approximately 74 percent of China’s primary energy consumption. China consumes more coal than Europe, Japan and the United States combined, which make up 40 percent of the world’s total. [1] China’s coal use continues to grow every year, and it is estimated that 90 percent of the rise in world coal consumption is from China. [2] Despite investments...

On questioning 126 households, only 9 (7.1 percent) used iodized salt whilst 74 (58.7 percent) households used only uniodized coarse salt and 7 (5.6 percent) used only uniodized fine salt. The remaining 36 (28.6 percent) households used both fine and coarse uniodized salt. Undoubtedly at this point in time legislation on "table" salt iodization must be interpreted to mean not only the iodizatio...

Eighty-four women at high risk for ovarian cancer by having first-degree relatives with epithelial ovarian cancer participated in a newly established, early ovarian cancer detection program at Yale University. Participants were to be evaluated with physical examinations and circulating tumor markers at entry and every six months thereafter. Endovaginal ultrasound and color Doppler flow studies ...

To evaluate the accuracy of clinical judgment in the diagnosis and treatment of nosocomial pneumonia in ventilated patients, we studied 84 patients suspected of having nosocomial pneumonia because of the presence of a new pulmonary infiltrate and purulent tracheal secretions. We prospectively evaluated the accuracy of diagnostic predictions and therapeutic plans independently formulated by a te...

In the 1995 Food Marketing Institute Survey, 77 percent of shoppers were completely or mostly confident that foods in their supermarket are safe. This percentage is still lower than the 90 percent in 1985-88, or even the 82 percent in 1991, but is increasing. Respondents were asked to volunteer their concerns as to "threats" to the food supply. Spoilage was given by 52 percent (significantly hi...
