Purpose: To compare the effectiveness between wearing a conventional hydrogel vifilcon A bandage contact lens (BCL) and a silicone hydrogel lotrafilcon A BCL after laser-assisted subepithelial keratomileusis (LASEK). Methods: LASEK was performed on 38 eyes of 19 patients. Each patient was fitted with a silicone hydrogel lotrafilcon A lens in one eye and a conventional hydrogel vifilcon A lens in the other eye. The patient was masked on the type of lens in each eye. General preference between the two types of lenses, subjective symptoms (pain, photophobia, tearing, dryness, and foreign body sensation; graded as 0 to 4), and the area of non-viable corneal epithelium were assessed in each eye at one and four days after surgery. Results: Patients reported preferring the lotrafilcon A lens to vifilcon A at 1 (79%) and 4 (74%) days after LASEK. The mean symptom scores of tearing and foreign body sensation at 1 day after surgery (P=0.012 and P=0.034, respectively) and foreign body sensation at 4 days after surgery (P=0.027) were significantly lower in the lotrafilcon A group. The mean area of the non-viable corneal epithelium was smaller in the lotrafilcon A lens group at 1 day and 4 days after surgery, although not statistically significant. Conclusions: Patients better tolerated the silicone hydrogel lotrafilcon A BCL compared with the conventional hydrogel vifilcon A BCL. The mean symptom scores were significantly lower in the lotrafilcon A group at both 1 and 4 days after LASEK.

Objectives: The aims of study were developing cut-off value of Yin-deficiency questionnaire (YDQ) for diagnosis of Yin-deficiency (YD) and compare diagnostic ability between YDQ and Yin-deficiency scale score (YDS) in xerostomia patients. Methods: We recruited 58 xerostomia patients. They were diagnosed YD or non-YD by 3 Korean medicine doctors (KMD). We assessed YD using YDQ and YDS. We evaluated xerostomia using VAS, Dry Mouth Symptom Questionnaire (DMSQ), Salivary Flow Rate (SFR), oral moisture on buccal mucosa and tongue surface (OMB and OMT). We surveyed tongue coatings using Winkel Tongue Coating Index (WTCI). Results: We diagnosed 23 patients YD and 35 patients non-YD. There were no significant differences of age, sex and body mass index between the YD and non-YD groups. Using receiver operating characteristic curve analysis, the optimal cut-off value of YDQ was defined as 304. Sensitivity, specificity and Youden index of YDQ were 86.96%, 71.43% and 1.5839 respectively. Using Cohen's coefficient of agreement, we found that degree of agreement between KMD and YDQ diagnosis was moderate (${\kappa}$=0.524, p<0.001). Using Pearson's correlation analysis, we found concurrent validity of YDQ and YDS were significant correlated. Using area under curve value, we found diagnostic ability between YDQ and YDS were not significantly different (p=0.505), but there were more strong correlations between DMSQ-symptoms and YDQ (r=0.731, p<0.001) than correlations between DMSQ-symptoms and YDS (r=0.418, p<0.01). Conclusions: The cut-off value of YDQ can diagnose YD in xerostomia and diagnostic ability of YDQ in xerostomia is better than YDS.

Objectives : This study was designed to investigate the difference between genuine and pseudo halitosis about qi stagnation and stress. Methods : We recruited 63 halitosis patients who visited the halitosis clinic in the Kyung Hee University Korean Medicine Hospital from June 2012 to August 2013. We classified the halitosis patients into two groups, genuine and pseudo halitosis based on organoleptic assesment (OLT) score and evaluated the severity of self-reported halitosis using visual analog scale (VAS), amount of sulfide compounds using Halimeter, qi stagnation level using qi stagnation questionnaire and stress levels using heart rate variability (HRV) parameters. Results : Comparing the genuine halitosis group and the pseudo halitosis group, there was no significant difference in VAS of halitosis but significant difference in halimeter score. Distribution of qi stagnation and non-qi stagnation groups was significantly different between genuine and pseudo halitosis. Compared to the genuine halitosis group, the pseudo halitosis group showed a significant higher value of low frequency/high frequency ratio (LF/HF ratio). Conclusions : The result of this study suggest that there is significant difference about qi stagnation and stress level between genuine halitosis and pseudo halitosis patients, so when approaching pseudo halitosis patients, we should consider their psychological and emotional status.
