BACKGROUND: It is well known that there is an adverse effect of longterm cigarette smoking on pulmonary function. But there are few reports about the effect of different habits of cigarette smoking on pulmonary function. Some smokers think that different habits of cigarette smoking are more safe than athers and this can be, an obstacle to the education of smoking cessation. Therefore, we have obtained applicable basic information for education of smoking cessation by analysing the effects of different habits of cigarette smoking on pulmonary function. METHODS: We surveyed current smokers on different habits of smoking who had performed puhnonary function test at the pulmonary function laboratory of one tertiary hospital in Seoul and pulmonary function test was done as a part of comprehensive health check-up at health promotion center of one secondary hospital at Ulsan from May 1998 to July 1998. We analysed the effects of different habits of cigarette smoking on pulmonary function in 160 subjects who has no specific respiratory disease. RESULTS: The factors were age, height, weight and amount of total smoking that had effect on pulmonary function. There were six different habits of smoking that we could analyse time of first smoking after sleep, average time of one cigarette smoked, current amount of smoking, length of one cigarette smoked, effort to quit smoking, smoking with drinking and all these six habits of sking had no relationship with the results of the pulmonary function test. CONCLUSIONS: The damage in pulmonary function was not protected by different habits of smoking that were previously known to be more safe or healthy. Therefore, we concluded that smoking cessation is the only way to prevent the damage in pulmonary function from cigarette smoking.

PURPOSE: To assess the usefulness of diffusion-weighted imaging(DWI) in evaluating serial parenchymal changesin renal infarction induced by renal artery ligation, by comparing this with the conventional spin echo techniqueand correlating the results with the histopathological findings. MATERIALS AND METHODS: In 22 rabbits, renalinfarction was induced by ligation of the renal artery. Spin-echo T1-weighted imaging(T1WI), turbo spin-echo(TSE)T2-weighted imaging(T2WI), and DWI were performed, using a 1.5-T superconductive unit, at 30 minutes, 1 hour, 2,3, 6, 12 and 24 hours, and 2, 3, 7 and 20 days after left renal artery ligation. Changes in signal intensity onT1WI, T2WI, and DWI were correlated with histopathologic findings. RESULTS: On MR images obtained 30 minutesafter ligation, the signal intensity of affected kidney was not significantly different from that of contralateralkidney, as seen on T1WI and T2WI, but was noticeably higher on DWI. On T2WI, the signal intensity ratio(SIR) wasslightly higher over time from 30 minutes to 2 days after ligation, and then decreased slightly. The SIR on DWIincreased abruptly at 30 minutes, remained high until 12 hours, and then fell, returning to close to the normalrange at between 2 and 3 days. It fell further, below the normal range, until 20 days after ligation. The mainhistopathologic findings after ligation were congestion and swelling of renal tubules (1-6 hours after ligation),degeneration and necrosis of renal tubules (12 hours - 2 days), coagulation necrosis of renal tubules(3 days),collection of cellular debris between renal tubules (7 days), and proliferation of fibroblast between renaltubules (20 days). CONCLUSION: Diffusion-weighted imaging is useful for the detection of hyperacute renalinfarction, and the apparent diffusion coefficient may provide additional information concerning its evolution.

PURPOSE: To compare single-shot echo-planar MR imaging(EPI) with breath-hold fast T2-weighted imaging(HASTEor Turbo spin-echo T2WI) for evaluation of the role of EPI in distinguishing small hepatocellular carcinoma fromcavernous hemangioma. MATERIALS AND METHODS: We retrospectively evaluated MR images of 35 patients (21 cases ofsmall HCC and 14 cases of cavernous hemangioma). EPI and breath-hold fast T2WI images were obtained and comparedon the basis of lesion detection sensitivity, lesion-to-liver signal intensity ratio(SIR), contrast ratio(CT), andlesion-to-liver contrast to noise ratio(CNR). RESULTS: For the detection of small HCC, the sensitivity of EPI andbreath-hold fast T2WI were equal in 14 of 21 cases(71.4%). The detection sensitivity of cavernous hemangioma withEPI and breath-hold fast T2WI was 100%(14/14). Mean SIR on breath-hold fast T2WI was 2.02+/-0.45 for small HCC and3.65+/-0.97 for cavernous hemangioma; on EPI, the corresponding figures wer 2.91+/-0.57 and 6.98+/-1.37. Mean CR onbreath-hold fast T2WI was 1.16+/-0.58 for small HCC and 2.65+/-0.57 for cavernous hemangioma; On EPI, the figuresobtained were 2.27+/-0.52 and 6.26+/-2.19, respectively. Mean CNR on breath-hold fast T2WI was 14.24+/- 4.098 forsmall HCC and 50.28+/-10.96 for cavernous hemangioma, while on EPI, the corresponding figures were 13.84+/-3.02 and45.44+/-11.21. CONCLUSION: In detecting focal hepatic mass, the sensitivity of EPI and breath-hold fast T2WI arecomparable; for the diagnosis of small HCC and cavernous hemangioma, EPI can provide additional information.

PURPOSE: To evaluate the findings and differential points of ovarian fibroma and subserosal leiomyoma, as seen on MR images. MATERIALS AND METHODS: The MR imaging findings of 31 surgically confirmed cases of ovarian fibroma(n=6) and subserosal leiomyoma (n=25 ; 28 lesions) were evaluated. Multiplanar T1- and T2-weighted and postcon-trast T1-weighted images were obtained using a 1.5T MR unit, and histologic examination was also performed. The MR findings were analyzed in terms of signal intensity, the presence and definition of margin, the histo-logic finding of hyperintense lesion on T2-weighted images, the presence of the bridging vessel sign, degree of enhancement, and the presence of ipsilateral ovary and ascites. RESULTS: Both fibromas and leiomyomas showed hypo-or isointensity compared with uterine myometrium on T1-weighted images and compared with skeletal muscle on T2-weighted images. The latter revealed intratu-moral hyperintense lesions in most cases of ovarian fibroma and subserosal leiomyoma. Three of four ovarian fibromas had a well defined margin after cystic change, but in 24 of 26 subserosal leiomyomas the margin was ill defined. The "bridging vessel sign" was visible only in subserosal leiomyomas (22/28), and in all cases the enhancement of ovarian fibromas were less than that of myomtetrium. Subserosal leiomyomas (12/28), seen on enhancement as isointense or hyperintense to myometrium, showed a greater degree of enhancement than ovarian fibromas (0/6). Ipsilateral ovary was rarely seen in ovarian fibromas (1/6), but commonly seen in sub-serosal leiomyomas (20/25). Ascites was present in one case of ovarian fibroma. CONCLUSION: A defined margin of an intratumoral hyperintense lesion, as seen on T2-weighted images, and the presence or absence of the "bridging vessel sign" and ipsilateral ovary are useful signs when differentiating be-tween ovarian fibromas and subserosal leiomyomas.

Background: As rhinoplasty techniques have become more complex, surgeons often need more than what septal or conchal cartilage can provide. While costal cartilage became more popular for that reason, some surgeons are still uncomfortable with its invasiveness and donor site morbidity. Here, we used lyophilized allogeneic costal cartilage for septorhinoplasty and investigated its safety and usefulness. Methods: The costal cartilage was harvested from a cadaveric donor and treated via multiple steps, including defatting and lyophilization, to remove all viable cells and antigenicity. The cartilage was then stored at room temperature and rehydrated 24 hours before use. Lyophilized cartilage allografts were used in 20 patients. Three types of septal graft were performed — spreader, batten, and extension — to correct septal or columellar deviation and enhance the nasal tip. Results: The mean follow-up period was 4.3 years. In all cases, the graft successfully met the rhinoplasty purpose. No significant deformation was detected in any of the patients. Although warping was observed in one patient (5%), there was no case of clinical infection, extrusion, or graft removal and no revisional surgery for an unfavorable aesthetic result. Conclusions Lyophilized allogeneic cartilage was used for septorhinoplasty very safely and effectively. It can be carved into any shape and has all other properties required for perfectly replacing autologous costal cartilage. The main advantage of cartilage allografts is a limitless supply of high-quality cartilage without donor site morbidity. The disadvantages include the need for special facilities and manpower and extra covering cost.

We reported a case of huge cystic trigeminal neurinoma. The patient was 35 year old female with trigeminal nerve dysfunction and hemiparesis. The computed tomography disclosed a huge cystic low density mass at the temporal base and suprasellar cistern that extended to cerebellopontine cistern through the tentorium, and enlargement of Meckel's cave on coronal scan. Through the infratemporal and retromastoid suboccipital approach, the cystic content was aspirated and cyst wall was removed. The cystic change of neurinoma may be due to mucoid degeneration and liquifaction.

BACKGROUND: Pressure support ventilation(PSV) is a new form of mechanical ventilatory support that assists spontaneous inspiratory effort of an intubated patient with a clinician-selected amount of positive airway pressure. Low level pressure support during inspiration can overcome the resistive component of inspiratory work imposed by ah endotracheal tube. However the clinical efficacy of PSV as a weaning method has not been established yet. Object : The aim of study was to evaluate the efficacy of PSV when it is added to intermittent mandatory ventilation (IMV) in facilitating weaning process compared to IMV mode alone. METHOD: When the subject patients became clinically stable with their arterial blood gas analysis in acceptable range, they underwent weaning process either by IMV alone or by IMV plus PSV. The level of pressure support was held constant through the weaning period. For the patients who required mechanical ventilation for less than 72hr, 2h weaning trial was performed with IMV rate starting from 6/min. For the patients who required mechanical ventilation more than 72 hr, 7 hr weaning retrial was performed with IMV rate starting from 8/min. For the patients who failed three consecutive trials of weaning, retrial of weaning was attempted over 3 days with IMV rate starting from 8/min. Clinical characteristics, APACHE II score and nutritional status were compared. For all patients, heart rate, mean blood pressure and respiratory rate were mornitored for 48 hrs after weaning trial started. RESULTS: The total number of weaning trial was 37 in 23 patients(18 by IMV, 19 by IMV+PSV). Total ventilation time, APACHE II score and nutritional status were not statistically different between the two groups. The weaning success rate were not statistically different(38.3% by IMV, 42.1% by IMV+PSV) and the changes of mean blood pressure, heart rate, respiratory rate during first 48 hours were not different between the two groups. CONCLUSION: Low level PSV when added to IMV for weaning trial does not seem to improve the success rate of weaning from mechanical ventilation. PSV at 10cm H2O did not induce significant physiologic changes during weaning process.
