Double-orifice mitral valve is a relatively rare congenital abnormality, usually discovered at autopsy or surgery. In most cases, the double-orifice mitral valve causes no hemodynamic effects, sometimes it is regurgitant, and rarely is stenotic. Appreciation of this echocardiographic abnormality is important because double orifice mitral valve is often associated with other congenital anomalies and this echocardiographic findings may be confused with other cardiac abnormalities. The authors report a case of isolated congenital double-orifice mitral valve in a 42-year-old woman. Data from the literature are reviewed and the echocardiographic images of the malformation are described.

Purpose: The correlation between the existence of the preoperative condition of ≥10 prism diopters (PD) in patients with basic type of intermittent exotropia (IXT) and postoperative outcomes was analyzed.
Methods: The medical records of patients that underwent surgery for IXT were analyzed retrospectively. The analysis was conducted by dividing the patients into a group with change of <10 PD (group 1) and ≥10 PD (group 2) before the time of the surgery. Patients who received at least 6 months of follow-up after surgery were included. The age, sex, angle of deviation and stereoacuity of the patients were studied. Surgical success was defined as exodeviation of <10 PD or esodeviation of <4 PD at the final visit after the surgery. The correlation between clinical factors and surgical success rate was analyzed by using correlative analysis.
Results: A total of 129 patients participated in the study. There were 108 (83.7%) and 21 (16.3%) patients in groups 1 and 2, respectively. There were 89 (82.4%) and 17 (80.1%) patients with surgical successes in groups 1 and 2, respectively (p = 0.18). Moreover, 13 (12.0%) patients in group 1 and three (14.3%) patients in group 2 required reoperation, showing no significant difference (p = 0.12). There was no statistically significant correlation between surgical success and preoperative change of angle of deviation <10 PD (odds ratio, 1.78; p = 0.17).
Conclusions Among the patients with basic type of IXT subjected to the analysis, 16.3% had a change of ≥10 PD before surgery, and there was no significant correlation between surgical success and preoperative change of angle of deviation.

In an epidemiological study of metal workers exposed to metalworking fluids(MWF), the prevalence time of evoultion, seasonal occurrence and clinical type of contact dermatitis were investigated. Composinal analyses of MWF with HPLC, dermatological examination and two consecutive questionnaire surveys were conducted. Study population was divided into two groups ; workers contact to cutting oil and workers contact to rust preventive oil. In the analysis of MWF, aliphatic hydrocarbons, having 12-20 carbons, was most common composition(49.04%) of cutting oil otherwise, major contents (90.99%) of the rust preventives oil were aliphatic hydrocarbons composed of 6-9 carbons. The frequency (point prevalence) of contact dermatitis(CD) was 7(12.7 per 100 subjects) in the dermatological examination of 55 workers. As the result of second survey for contact dermatitis, cumulative prevalence of oil working full-time and recent 1 year prevalence in two groups were 28.0, 16.7 and 15.1, 12.5 per 100 subjects. There were no difference in the prevalence of CD by oil, age, oil contact duration. Summer is the most common evolution season in workers exposed to cuttiogs, but not in workers exposed to rust preventive oil. Major clinical type of CD was erythematous papules in both groups. It presents the importance of preventive measures that 51.1% suffer from contact dermatitis had medical care at their own expense, and 47.1% of them felt serious about their contact dermatitis. From the fact that 68.6% think cotton gloves protective apparatus, we emphasize the need for health education.

Purpose: To compare the myopic progression between pateints only wearing glasses (Myopia group) and patients using low-dose atropine with glasses (Atropine group) for 1 years or more. Methods: Medical records were retrospectively reviewed. Low-dose atropine (atropine sulfate 0.125%) and artificial tear eyedrops (sodium hyaluronate 0.1%) were applied immediately afterwards to both eyes daily to the Atropine group. All children regularly visited our clinic for measurement of refractive power, axial length, near-point accomodation, pupil diameter, symptoms (glare, near-work disturbance, headache, allergic reaction, dryness) were recorded. Results: A total of 240 patients were included. Atropine was prescribed for 138 patients, the Atropine group, and the remaining 102 patients constituted the Myopia group, and were observed for 20.3 ± 7.8 months. In the initial visit, the mean refractive power was -4.2 ± 1.4 diopters (D) for the Myopia group, -4.8 ± 1.9 D for the Atropine group, and the mean axial length was 24.5 ± 0.6 mm for the Myopia group, 25.1 ± 0.9 mm for the Atropine group. During follow up, in the Myopia group, mean refractive power changed -0.10 ± 0.12 D/month, and mean axial length changed 0.06 ± 0.01 mm/month. In the Atropine group, mean refractive power changed -0.03 ± 0.04 D/month, and mean axial length changed 0.02 ± 0.02 mm/month. The pupil size of the Atropine group was 6.1 ± 0.8 mm, with 30 patients presenting symptoms. Conclusions Refractive power progression and axial length elongation was significantly lesser in the Atropine group than the Myopic group. Pupil diameter increased in the Atropine group, and 21% of the Atropine group complained of symptoms. Using low-dose atropine for more than 1 year was effective to suppress refractive power progression and axial length elongation.

This study was performed to compare the incidence of posterior capsular opacity (PCO) and refractive errors between hydrophilic (ACR6D, Corneal (R) ) and hydrophobic (MA60BM, AcrySof (R) ) acrylic intraocular lenses (IOLs) over a 3-year follow-up after phacoemulsification surgery. The patients with AcrySof (R) implanted in one eye and Corneal (R) in the other eye were categorized as Group 1 (n=28), while those with one or both eyes implanted with IOLs of the same kind were categorized as Group 2 (AcrySof (R), n=90; Corneal (R), n=95). Refractive errors were evaluated at 3 months and 3 years postoperatively. The incidence of visually significant PCO was investigated 3 years postoperatively. Postoperative refractive values at 3 months were not significantly different between the two groups. However, refractive values at 3 years were significantly different between two IOLs in both groups [AcrySof (R) -0.37 +/- 0.43D, Corneal (R) -0.62 +/- 0.58D in Group 1 (p=0.04) ; AcrySof (R) -0.38 +/- 0.52, Corneal (R) -0.68 +/- 0.54 in Group 2 (p< 0.01) ]. The incidence of visually significant PCO was 14% and 32% in Group 1, and 13% and 28% in Group 2, for the AcrySof (R) and Corneal (R) implants, respectively. The incidence of visually significant PCO of hydrophilic acrylic IOLs was higher than that of hydrophobic acrylic IOLs in the 3-year follow-up. The postoperative 3-year refractive value of Corneal (R) showed myopic shift.

BACKGROUND: The accumulation of lipoprotein and monocyte in the intima of the arterial wall is the most important step of the development of coronary artery disease (CAD). Lipoprotein lipase (LPL) plays an anti-atherogenic role by lipolysis of triglyceride-rich lipoproteins, but, it may also act as a receptor of some lipoproteins and monocyte at the arterial wall and act as a atherogenic molecule. Previous studies showed somewhat contradictory results about the association of CAD and LPL polymorphisms and mutations. Racial and dietary difference may contribute to these contradictory results. In this study, we tried to find out the association of CAD and the genetic variation of the LPL (PvuII RFLP in intron 6, HindIII RFLP in intron 8 and Ser 447 Ter mutation in exon 9) in Korean population. METHOD AND RESULT: CAD patients (n=146), confirmed by coronary angiography and healthy Korean adult volunteers (n=110) were genotyped for PvuII/HindIII RFLP and Ser447Ter mutation of the LPL gene by PCR-digestion method. Between two groups, the genotype frequency of these genetic variations was not different. But, the genetic variations showed different effect on lipid profile and body mass index (BMI) in the CAD group and in the control group. In the CAD group, P1 allele carriers showed higher total cholesterol (P1P1+P1P2:P2P2=216+-51 mg/dl:198+/-38 mg/dl, p=0.039) and higher LDL cholesterol level (P1P1+P1P2:P2P2=143+/-46 mg/dl:126+/-36 mg/dl, p=0.047), and H1 allele carriers had lower Body mass index than non-carriers (23.8+/-2.3 kg/m2 :24.8+/-2.9 kg/m2 , p=0.047). In the control group, the Ser447Ter mutation carriers had higher HDL cholesterol level than non-carriers (59+/-10mg/dl versus 53+/-11mg/dl, p=0.049) and patients with P1 allele showed lower body mass index (P1P1+P1P2: P2P2=23.1+/-2.6 kg/m 2 :24.5+/-2.6 kg/m2 , p=0.006). CONCLUSION: In Korean, PvuII/HindIII RFLP and Ser447Ter mutation was not associated with CAD, and they showed different effect on the lipid profile and on the body mass index according to the study group. These results suggests that the phenotypic characteristics of the LPL gene of the Korean people are different from those of occidental people.
