BACKGROUND: Many countries have been legally prescribing health warning messages on cigarette packages as a part of their national policy of smoking cessation. This study was designed to evaluate the effectiveness for smoking cessation of graphic health warning labels, and compare them with the existing health warning messages. METHODS: From February to December 2002, we surveyed 103 smokers who were college students of fine arts. After letfing them see the graphic health warning labels, the self recorded questionnaires were collected. RESULTS: The effectiveness for the smoking cessation of the existing health warning messages was evaluated low, despite its wide recognition. But there was no difference between the visual effect and the effectiveness for the smoking cessation of the graphic health warning labels. The graphic health warning labels were more effective for the smoking cessation than the existing health warning messages, and it was the same in the subgroup analysis such as sex, degree of recognition of disease, and non- smoking planning. CONCLUSION: To quit smoking, it is reasonably concluded that the graphic health warning labels on cigarette packages was very effective. Hereafter, it is recommended more useful designs of graphic health warning labels be developed.

Patients with heart failure undergoing surgery that requires general anesthesia face substantial perioperative risks; however, clear guidelines are not available for anesthesia management in patients with a reduced left ventricular ejection fraction. Traditional intravenous and volatile anesthetics require careful administration to prevent severe hypotension and bradycardia in patients with heart failure. Remimazolam has emerged as a promising alternative to conventional anesthetics because of its reduced cardiovascular depressive effects. We present three cases illustrating the successful use of remimazolam to induce and maintain general anesthesia in patients with heart failure and reduced cardiac function. Our cases demonstrate the safe use of remimazolam for general anesthesia in patients with heart failure and a reduced ejection fraction.

PURPOSE: To assess the value of enteral contrast media for the evaluation of pelvic masses by MR imaging. MATERIALS AND METHODS: Between April and July 1998, 16 women with pelvic masses were examined by MRI. The origin of the lesion was the ovary in twelve cases, the uterus in three, and the sigmoid in one. Using a 1.5T scanner(Magnetom Vision, Siemens), T1-weighted axial spin echo(SE), T2-weighted turbo spin echo(TSE), two-dimensional fast low-angle shot(FLASH 2D), and half-Fourier TSE(HASTE) images were obtained in all patients after the administration of Magnevist Enteral (Shering, Berlin, Germany). In each MR imaging sequence, distinction between the lesion and adjacent bowel (1, not distinguished; 2, partly distinguished; 3, clearly distinguished), artifact (0, absent; 1, mild; 2, severe), image quality (1, poor; 2, fair; 3, good), were compared before and after the use of enteral contrast media. Changes in MRI impression after the use of enteral contrast media were also evaluated. Two radiologists reached a consensus after reviewing the images. Statistical significance was determined by Wilcoxon's signed ranked test. RESULTS: For distinguishing lesions, SE T1WI and FLASH 2D with enteral contrast media were significantly superior to SE T1WI without enteral contrast media (p<0.05). With regard to image quality, FLASH 2D and HASTE, both with enteral contrast media, were significantly superior to SE T1WI and TSE T2WI, respectively, both without enteral contrast media (p<0.05). Artefacts were more frequently found after the application of enteral contrast media in conventional sequences but were not present in breathhold sequences. In two patients, MRI impression changed after the appilication of enteral contrast media. CONCLUSION: In a limited number of cases, enteral contrast media improved lesion detection, image quality and diagnostic accuracy when breathhold fast MR imaging was applied.

PURPOSE: Spontaneous Intracranial Hypotension (SIH) is rare condition and may accompany other clinical symptoms which inhibit accurate diagnosis in an emergency department (ER). Only a few studies have reported the clinical characteristics and root causes associated with SIH. This study evaluates the rate of accuracy of SIH diagnosis and compares clinical characteristics and diagnostic test results for correct versus incorrect diagnosis groups. METHODS: Medical records of SIH patients admitted to an emergency department (ER) over a twelve year period were retrospectively reviewed. Patients were grouped as having received correct or incorrect diagnosis, and their clinical characteristics and diagnostic test results were compared. In the incorrect diagnosis group, the number of times they were misdiagnosed, and the specialties of the clinic (s) they visited prior to arrival at this ER were reviewed. RESULTS: Adhering to the inclusion criteria of our study, 72 patients were enrolled with 54 patients in the correct diagnosis group and 18 patients in the incorrect diagnosis group. Of the twenty one cases in the incorrect diagnosis group, the majority 7 cases (33.3%) had been examined by an emergency physician. Among the clinical symptoms observed, there was significant variability in the location of the headache (p=0.020) and time interval between symptom onset and diagnosis (p=0.035). CONCLUSION: There were no differences in most of the clinical observations and diagnostic test results between the correct and incorrect diagnosis groups. To improve the correct diagnosis rate, it is suggested to have 'SIH' included as a differential diagnosis when encountering patients reporting headache in the emergency department. Emergency physicians should be required to recognize clinical SIH characteristics such as orthostatic headache.
