PURPOSE: To analyze the incidence and clinical course of epithelial ingrowth after laser in situ keratomileusis (LASIK) using a femtosecond laser. METHODS: We retrospectively evaluated the results of 1158 eyes of 581 patients who received LASIK with the flap created by a femtosecond laser from February 2006 to March 2009 at our institute. We investigated the incidence and clinical course of LASIK in which the flap was created by a femtosecond laser. RESULTS: Epithelial ingrowth was first detected one week after surgery in 12 (57%) of 21 eyes and within one month in 19 eyes (90%). Epithelial ingrowth was localized most commonly near the temporal and nasal flap edge in 12 eyes (57%). In two eyes (9.5%), an isolated ingrowth mass was located in the pupillary area. The development of more than 2.0 mm of epithelial ingrowth was observed in three eyes (0.25%). Among 28 eyes with loose epithelium or epithelial detachment during surgery, epithelial ingrowth was observed in six eyes (21.4%) compared with 15 (1.32%) of 1130 eyes without loose epithelium or epithelial detachment. Therefore, epithelial detachment during surgery was significantly associated with epithelial ingrowth (p = 0.00). CONCLUSIONS: In LASIK in which the flap is created by a femtosecond laser, damage to the epithelial layer increases the chances of epithelial ingrowth. Therefore, avoiding epithelial defects with a gentle maneuver is needed to reduce the chance of epithelial ingrowth during surgery.

The purpose of this study was to compare the fitness of the IPS Empress ceramic crowns according to margin type such as bevel, shoulder, rounded shoulder, shoulder with bevel, rounded shoulder with bevel and grooved bevel. After 10 experimental dies were constructed for each group, the IPS Empress ceramic crowns were fabricated on the dies, cemented with resin cement(Bistite resin cement, Tokuyama Soda Co. Ltd., Japan) and embeded in clear epoxy resin. Each specimen was sectioned with a low speed diamond saw in both the faciopalatal and the mesiodistal direction. The cement film thickness was measured with a measuring microscope. The obtained results were as follows : 1. The fitness at the external margin was good in the following order: rounded shoulder(28.99), shoulder with bevel(31.33), grooved bevel(31.79), rounded shoulder with bevel(34.65), bevel(35.02) and shoulder(35.08). However there is no significant statistical difference. 2. The fitness at the internal margin of bevel(25.75), rounded shoulder(31.24), shoulder with bevel(32.07) and rounded shoulder with bevel(34.45) was better than that of shoulder(47.98). 3. The fitness at the axial surface of bevel(26.58) was better than that of shoulder(49.59). 4. The fitness at the central fossa was good in the following order: shoulder with bevel(38.88), grooved bevel(40.46) rounded shoulder with shoulder(46.29), shoulder(48.91), bevel(49.47) and rounded bevel(52.07). However there is no significant statistical difference. 5. Overall fitness of bevel(29.71), rounded shoulder(32.49) and shoulder with bevel(34.47) was better than that of shoulder(44.73).

The incidence of the cutaneous tuberculosis has shown a steady decline over the past decades. This parallels the decreasing incidence of pulmonary tuberculosis. We experienced 5 cases of cutaneous tuberculosis from January 1990 to February 1991. We present herein 4 cases of cutaneous tuberculosis. They were 3 cases of vulgaris and 1 case of tuberculosis verrucosa cutis. Mantoux tests were done except one case and were reactive in all cases. Culture for Mycobacterium tuberculosis were done but Mycobacterium tuberculosis were not cultivated in the all cases. Histopathological findings showed tuberculoid granulomas in the dermis except one case and no acid fast bacilli were demonstrated on AFB stains.

BACKGROUND: The self-inflating bag-valve resuscitator is an useful breathing support equipment in the cardiopulmonary resuscitation, the transportation of patients who required ventilation assist, or respiratory therapy. The inspiratory oxygen concentration (FiO2) or tidal volume (VT) delivered to the patient depends on various conditions during bag-valve ventilation. METHODS: During bag-valve ventilation without a reservoir at oxygen flow rates of 10 l/min, we evaluated fifty six volunteers to determine the FiO2 and VT at ventilatory frequencies of 10, 12 and 15 cycles per minute and to observe the effect of hand size and grasp power on FiO2 and VT in two-hand compression methods. RESULT: The FiO2 at frequency of 10 cycles/min were 50.1% and it was higher than other ventilatory frequencies. However, the VT was not statistically different among the changes of ventilatory frequency. In the change of VT according to characteristics of the hand, the operator's hand size exerted influence on VT(larger vs. smaller ; 942ml vs. 885ml, p<0.05), but the grasp power of the hand did not significantly affect. Separate analyses with size or grasp power of the hand failed to reveal significant differences of the FiO2. CONCLUSION: The results suggest that a slowing of ventilatory frequency within the allowable ranges for adequate gas exchange increase the FiO2 during bag-valve ventilation without reservoir, and that hand size may exert influence on the VT without FiO2 changes but grasp power may not be a contributing factor to the VT or FiO2 changes.

BACKGROUND: Non ulcer dyspepsia(NUD) is a commonly encountered disease at the primary practice. The relations of functional gastrointestinal disorder and Irritable bowel syndrome with depression or stress were suggested by previous studies. But the contributions of the anxiety, depression and stress as a whole to the NUD were not assessed. In this study, we wanted to show the associations of the anxiety, depression and stress levels with NUD. METHODS: This study was performed by case and control method from Aug. 1 to Sep. 7 at the outpatient department of Family Medicine and at the Health Management and Service department in Pusan Paik Hospital. The both groups were matched by sex and age. The case was defined who has three or more symptoms among nine upper gastrointestinal symtoms like dyspepsia, epigastric pain and anorexia etc. frequently or alwalys and who has no ulcer at the gastrofibroscope. The anxiety, depression, stress levels were measured by questionnaire which was validated by previous studies. The questionnaire was composed of Trait-STAI, Jung's Self Depression Scale(SDS), Modified BEPSI, and Grobal Assessment of Recent Stress(GARS) Scale. RESULTS: The total subjects were 136 persons(NUD group : 86 persons/control group : 86 persons). There were. significant differances in regularity of diet(P<0.001), levels of education(P=0.009), and history of medications(P<0.001) between two groups. The two group had higher scores than the control group in the depression score, anxiety score and modified BEPSI score(P<0.001). All items in GARS showed higher scores in NUD group than in control group(P<0.001). CONCLUSIONS: NUD group had higher degree of anxiety and depression than the control group. It seems that the NUD may have streeful status. When we encounter the NUD in outpatiet department, we had better consider the underlying psychogenic or stressful conditions.

Acute appendicitis is the most common operative disease in general surgery, but it is not also rate disease to see in other clinical department such as Internal Medicine and Obstetric and Gynecology, because it reqnires to differenciate from many other diseases which have similar symptoms. Expecially, because the clipical aymptoms of acute appendicitis are not typieal in children, elderly, and women, it is hard to be diagnosed as acute appendicitis and it is often misdiagnosed as other disease. We performed colonoscopy due to be interpretated aa one of the colon diseases rather than acute appendicitis. But in colonoscopic findings, there were hyperemie and edematous change on the appendiceal orifice of cecum(cherry or acorn shape). So we report 5 cases of acute appendicitis diagnosed br colonoscopy.
