Purpose: We compared clinical outcomes including recurrence rate between amniotic membrane transplantation (AMT) and conjunctival autograft using fibrin glue and minimal conjunctival sutures for pterygium surgery. Methods: We retrospectively analyzed 217 eyes of 198 patients with pterygia who underwent surgery from May 2016 to December 2019. Pterygium excision was performed with conjunctival autograft or AMT, using fibrin glue with both. Recurrence rates and complications were evaluated between the two groups. Results: Postoperative recurrences were noted in one of 185 eyes (0.5%) in the conjunctival autograft group, and in six of 32 eyes (18.8%) in the AMT group. The recurrence rate was significantly lower in the conjunctival autograft group (p < 0.001). Logistic regression analysis revealed that conjunctival autograft was associated with a significantly lower risk of pterygium recurrence compared to AMT (odds ratio, 0.023; 95% confidence interval, 0.003-0.206; p = 0.001). No ocular complication was noted in both groups during follow-up. Conclusions Pterygium excision with conjunctival autograft using fibrin glue was more effective in preventing recurrence compared to AMT.

BACKGROUND: Color M-mode doppler echocardiography has been suggested as a new noninvasive technique for assessing left ventricular diastolic function. The present study was performed to define the feasibility and value of color M-mode echocardiography for the assessment of left ventricular diastolic function in patients with acute coronary syndrome. METHODS: Thirty six patients with acute myocardial infarcion and twenty three patients with unstable angina were included (M/F=41/18, 61+/-12.2 years). Doppler study was performed using ATL HDI-3000 within 24 hours after the attack. In color M-mode study, ROP was measured with 'Front wave method' and 'Baseline shift method'. The patients were grouped into three groups based on E/A ratio and deceleration time (DT) in transmitral flow and S/D ratio in pulmonary venous flow; Group I=Normal pattern (E/A>1, S/D>1, DT>140 ms), Group II=Impaired relaxation pattern (E/A<1, DT>140 ms) and Group III=Pseudonormal/Restrictive pattern (E/A>1.5, S/D<1, with or without DT< or =140 ms). RESULT: Twenty two, thirty four, and three patients were assigned to Group I, II, III, respectively. The ROP could be measured with 'Front wave method' in 50 patients (84.7%), but with 'Baseline shift method' only in 19 patients (32.2%). ROP with 'Front wave method' was 65+/-25.7, 61+/-35.6, 71+/-35.2 cm/sec in Group I, II, III, respectively. There was no statistically significant difference in the value of ROP between group I and II (p>0.05). CONCLUSION: The ROP seems not to reflect the diastolic function in acute coronary syndrome, although it is measurable with the 'Front wave method' in most cases. The measurement of the ROP with 'Baseline shift method' is not feasible in the patients with acute coronary syndrome.

PURPOSE: On the basis of evidence, we aimed to reevaluate the necessity of the empirical proton pump inhibitor (PPI) trial for children with suspected gastroesophageal reflux disease (GERD). METHODS: We analyzed the frequency of GERD in 85 school-age children with gastroesophageal reflux (GER) symptoms, who received 24-hour esophageal pH monitoring and/or upper endoscopy. According to the reflux index (RI), the children were classified into normal (RI <5%), intermediate (5%≤ RI <10%), or abnormal (RI ≥10%) groups. RESULTS: Fifty six were female and 29 were male. Their mean age was 12.6±0.5 (±standard deviation) years (range: 6.8–18.6). The RI analysis showed that the normal group included 76 patients (89.4%), the intermediate group included 6 patients (7.1%), and the abnormal group included 3 patients (3.5%). The DeMeester score was 5.93±4.65, 14.68±7.86 and 40.37±12.96 for the normal, intermediate and abnormal group, respectively (p=0.001). The longest reflux time was 5.56±6.00 minutes, 9.53±7.84 minutes, and 19.46±8.35 minutes in the normal, intermediate, and abnormal group, respectively (p=0.031). Endoscopic findings showed reflux esophagitis in 7 patients. On the basis of the Los Angeles Classification of Esophagitis, 5 of these patients were included in group A, 1 patient, in group B and 1 patient, in group C. CONCLUSION: The incidence of GERD was very low in school-age children with GER symptoms. Therefore, injudicious diagnostic PPI trials would be postponed until the actual prevalence of GERD is verified in future prospective studies.

In order to determine the status of Enterobius vermicularis infection among schoolchildren in suburban areas of Myanmar, 761 primary schoolchildren in 3 different townships around Yangon City were subjected to a survey using cello-tape anal swabs. The subjected schoolchildren were 383 boys and 378 girls who were 5-7 years of age. Only 1 anal swab was obtained from each child. The overall egg positive rate of E. vermicularis was 47.2% (359 positives), and sex difference was not remarkable (48.6% in boys and 45.8% in girls). However, the positive rate was the highest in South Dagon (54.6%) followed by Hlaing Thayar (43.8%) and North Dagon (34.8%). This difference was highly correlated with the living standards of the people in each township. Nucleotide sequence of the 5S rDNA from the eggs on the cello-tape (2 children) revealed 99.7% identity with that of E. vermicularis reported in GenBank. The results indicated that E. vermicularis infection is highly prevalent among primary schoolchildren around Yangon, Myanmar.

Paragonimiasis is a parasitic disease caused by Paragnonimus species. The primary site of infection is the lung, and extrapulmonary involvement is also reported. When infected with Paragonimus westermani, which is the dominant species in Korea, the central nervous system is frequently involved along with the liver, intestine, peritoneal cavity, retroperitoneum, and abdominal wall. Ectopic paragonimiasis raises diagnostic challenge since it is uncommon and may be confused with malignancy or other inflammatory diseases. Here, we report an ectopic paragonimiasis case initially presented with recurrent abdominal pain. The patient developed abdominal pain 3 times for the previous 3 years and the computed tomography (CT) of the abdomen revealed fluid collection with wall enhancement. Recurrent diverticulitis was initially suspected and part of the ascending colon was resected. However, the specimen showed intact colon wall without evidence of diverticulitis and multiple parasite eggs and granulomas were found instead. The size of about 70 μm, the presence of an operculum and relatively thick egg shell suggested eggs of Paragonimus species. With appropriate exposure history and a positive antibody test, the definitive diagnosis was made as peritoneal paragonimiasis.
