OBJECTIVE: Acute appendicitis is one of the most urgent surgical problems. Several factors have been considered as predictors of perforation, but this study focused on the change in pain pattern. The degree of pain and progression of appendicitis were analyzed assuming that the pain intensity would increase until the perforation and the degree of pain would decrease immediately after the perforation occurred. METHODS: In this study, 385 out of 467 patients, who were diagnosed with appendicitis in a single institution and aged between 15 and 65 years, were reviewed retrospectively. The patients' pain scores and the diameters of appendices were analyzed along with the accompanying complications. Correlation analysis and a Student's t-test were performed. RESULTS: In patients with complicated appendicitis, the mean numerical rating scale (NRS) was slightly higher than that of simple appendicitis, but there was no significant difference in the absolute value. Only the size of the appendix showed meaningful differences according to the combined computed tomography findings. The NRS distribution or appendiceal size did not correlate with the time duration from symptom onset. CONCLUSION: The appendiceal size tended to increase with progressing appendicitis. No significant correlation was observed between the patient's pain level and complications. The time duration from symptom onset did not show a relationship with the progression of appendicitis.

In the East, Probably one of the most commonly performed esthetic operation is the piercing of the earlobes for earring. the complication of this procedure includes infection, the formation of the hypertrophic scar or keloid, and tearing. Keloid formation is one of the disaterous common complications of the ear piercing. the patients regard the keloid as a cosmetic blemish and they complain that they cannot wear earrings. We have experienced 5 patients of earlobe keloid complicated from piercing of the earlobes. We used intralestional steroid njection, in conjunction with surgical excision and pressure therapy for treatment of the keloid. Among various techniques for reconstructing a piercing, we chose modified Pardue's method for artificial earlobe cleft after wide excision of the keloid. the result was good and satisfactory without any complication after 4 to 24 months of follow-up. the purpose of this paper is to present a simple method of treatment of the earlobe keloid with preservation of the perforation for an earring.

PURPOSE: The purpose of this study was to retrospectively compare the technical success and reliability of the measurements made using two 2-dimensional (2D) shear wave elastography (SWE) systems using the comb-push technique from the same manufacturer and to assess the intersystem reproducibility of the resultant liver stiffness (LS) measurements. METHODS: Ninety-four patients with suspected chronic liver diseases were included in this retrospective study. LS measurements were obtained using two 2D-SWE systems (LOGIQ E9 and LOGIQ S8) from the same manufacturer, with transient elastography (TE) serving as the reference standard, on the same day. The technical success rates and reliability of the measurements of the two 2D-SWE systems were compared. LS values measured using the two 2D-SWE systems and TE were correlated using Spearman correlation coefficients and 95% Bland-Altman limits of agreement. Thereafter, Bland-Altman limits of agreement and intraclass correlation coefficients (ICCs) were used to analyze the intersystem reproducibility of LS measurements. RESULTS: The two 2D-SWE systems showed similar technical success rates (98.9% for both) and reliability of LS measurements (92.3% for the LOGIQ E9, 91.2% for the LOGIQ S8; P=0.185). Despite the excellent correlation (ICC=0.92), the mean LS measurements obtained by the two 2D-SWE systems were significantly different (LOGIQ E9, 6.57±2.33 kPa; LOGIQ S8, 6.90±6.64 kPa; P=0.018). CONCLUSION: Significant intersystem variability was observed in the LS measurements made using the two 2D-SWE systems. Therefore, even 2D-SWE systems from the same manufacturer should not be used interchangeably in longitudinal follow-up.

PURPOSE: The purpose of this study was to compare the technical success rate and reliability of measurements made using three shear wave elastography (SWE) techniques and to assess the inter-platform reproducibility of the resultant liver stiffness measurements. METHODS: This prospective study included 54 patients with liver disease. Liver stiffness (LS) measurements were obtained using 2-point SWE techniques (Virtual Touch Quantification and S-Shearwave) and 2-dimensional (2D) SWE, with transient elastography (TE) serving as the reference standard. The technical success rates and measurement reliability of the three techniques were compared. LS values measured using the three SWE techniques and TE were compared using Spearman correlation coefficients and 95% Bland-Altman limits of agreement. Intra-class correlation coefficients (ICC) were used to analyze the inter-platform reproducibility of LS measurements. RESULTS: The three SWE techniques and TE showed similar technical success rates (P=0.682) but demonstrated significant differences in the reliability of LS measurements (P=0.006) and mean LS measurements (P<0.001). Despite strong correlations (r=0.73-0.94) between SWE systems, various degrees of inter-platform reproducibility (ICC, 0.58-0.92) were observed for the three SWE techniques. The best agreement was observed between S-Shearwave and TE (ICC, 0.92), and the worst agreement was observed between 2D-SWE and TE (ICC, 0.58). In the Bland-Altman analysis, a tendency toward lower LS values with the three SWE techniques than with TE in patients with F3 and F4 disease was observed. CONCLUSION: Significant inter-system variability was observed in LS measurements made using the three SWE techniques. Therefore, LS values measured using different SWE techniques should not be used interchangeably for longitudinal follow-up.

BACKGROUND: Endobroncheal intubation or extubation may occur accidentally when the patient's neck is flexed or extended even in the appropriate endotracheal intubation. The purpose of this study is to examine the effect of fixation or unfixation of the endotracheal tube at the teeth level on the displacement of its distal end when the patient's neck is extended or flexed. METHODS: This study was conducted in 37 patients who underwent endotracheal general anesthesia. The patients with the evidence of pathology in head, neck and chest were excluded from the study. Individual patient's displacement in endotracheal tube tip compared unfixed cases with fixed cases when the change of neck position. The moved distance was measured by fiberoptic bronchoscope. The data were statistically analyzed by Student's paired t-test. RESULTS: The endotracheal tube moved away from the carina when the patient's neck was extended, while it moved toward the carina when flexed in all cases. When the patient's neck was extended the average distance displaced 1.2 0.7 cm in fixed cases and 1.1 0.9 cm in unfixed cases. when the neck was flexed, they were 1.2 0.5 cm and 1.0 0.8 cm respectively. There were not statistically significant between the fixed and the unfixed cases. CONCLUSIONS: It is concluded that the displacement of the endotracheal tube is not related to its fixation or unfixation at the teeth level and therefore, unfixation does not provide any benefits in terms of the displacement of the distal end of the tube in adult trachea.

OBJECTIVE: Using Lee et al (1996) model, we assessed the effect of opioid within the PAG on the manifestations of the neuropathic pain, and we studied the effects of naloxone on the analgesic effects of opioid. METHOD: Under pentobarbital anesthesia, male Sprague-Dawley rats were implanted with cannula in the ventral (n=10) and dorsal (n=6) PAG after the unilateral tibial and sural nerves were ligated and cut, leaving the common peroneal nerve intact. Pain sensitivity was assessed using the von Frey filament (8 mN) and acetone applied to the sensitive area for 1 week postoperatively. Rats with neuropathic pain were intracerebrally microinjected with DAMGO (0.1microgram/5microliter) and enkephaline (20microgram/5microliter) into the ventral and dorsal PAG and the pain sensitivity was assessed. Naloxone was injected to assess the observed change of pain sensitivity. RESULTS: Intracerebral microinjection of DAMGO and enkephaline into the ventral PAG, but not the dorsal PAG, increased the pain threshold which was reversed by naloxone. CONCLUSION: The results suggest that stimulation of the ventral PAG in neuropathic rats may reduce neuropathic pain via opioid-mediating pathway of the descending pain inhibition system.

PURPOSE: To evaluate the effectiveness of percutaneous catheter drainage in treatment of the lung abscess. MATERIALS AND METHODS: We treated the lung abscesses in 14 patients(12 men, 2 women), who did not respond to medical therapy, by percutaneous catheter drainage under fiuoroscopic or ultrasound guidance. One abscess due to infacted bulla was managed by combination treatment with alcohol sclerosing therapy. Patients were followed by serial chest radiographs every three days and the amount of drained or aspirated pus evaluated. The treatment effect and recurrence were followed by chest PA and lateral chest at one week after removal of drainage catheter. RESULTS: Thirteen patients(93%) recovered clinically and radiologically within 3 days. In 10 patients, drainage catheter could be removed within 2 weeks, and three patients, the catheter was keept longer. Most complications were mild ;vague to moderate chest pain(n=14), mild hemoptysis(n=2), and pneumothorax(n=I). One man who suffered from far advanced pulmonary tuberculosis died of asphyxia caused by massive hemoptysis 16 days after percutaneous drainage. CONCLUSION: Percutaneous catheter drainage is a safe and effective method for treating lung abscess.

PURPOSE: Conventional contrast dacryocystography(C-DCG) has been used mainly for anatomical assessment of the lacrimal drainage apparatus, due to its limited information on the dynamics of the lacrimal system, and thus correlation role in epiphora. The purpose of study was to improve the diagnostic value in epiphora by utilizing RI dacryocystography(RI-DCG) with quantitative criteria. MATERIALS AND METHODS: The patient for RI dacryocystography set erect with the head fixed in front of gamma camera fitted with a standard 6 mm pinhole collimater. Both eyes of 85 patients(170 eyes) were scanned with 99rnTc-pertechnetate followed by conventional dacryocystography. The data from gamma camera were recorded simultaneously on a computer system for subsequent quantitative analysis. RESULTS: In 94 of 96 eyes without epiphora, RI-DCG was correlated with normal C-DCG and % of emptying was at least over 50%. In 58 of 74 eyes with epiphora, RI-DCG was correlated with abnormal C-DCG and % of emptying was at most below 50%. In 16 eyes with functional block, quantitative RI-DCG showed abnormal % of emptying. CONCLUSION: Nuclear DCG with quantitation had higher diagnostic yield in functional block and correlated higher with epiphora. Thus nuclear DCG with quantitation would be a valuable functional test after postprocedures such as dacryocystoplasty.

OBJECTIVES: The object of this study was to indentify characteristics of cardiovascular disease in the employed population in comparson with the non-employed group. METHODS: The study subjects were patients aged 20~65 from 3 university based hospital emergency centers and a structured questionnaire were used for comparing the characteristics of cardiovascular disease according to employment status. Multivariate logistic regression was used to analyze the association between employment status and cardiovascular disease risk factors. RESULTS: Among the patients, 573 people were employed (482 males, 91 females) and 251 were non-employed (117 males, 134 females). Compared to the non-employed group, the employed group was distinctive in that it contained patients of younger age, had a male dominant gender distribution, and a higher proportion of smoking and drinking patients. The employed group was less likely to be previously-diagnosed with diabetes, hypertension, chronic renal failure, cardiovascular disease, or cerebrovascular disease. The employed group was generally more stressed out but there was no significant differences in sleeping time. Infarction was more frequent in the employed group, but hemorrhage was more frequent in the non-employed group. According to the multivariate logistic regression analysis results, the odds ratio of drinking and stress was 1.89(95% CI: 1.25~2.86) and 2.68(95% CI: 1.80~3.99) respectively. CONCLUSIONS: Infarction was more frequent in the employed group. Drinking and stress were also more frequent in the employed group. The results of this study don't necessarily mean that stress and drinking are more important than other risk factors but, it means stress and drinking control are more important in the employed group compared to the non-employed group.
