We analyzed ERCP findings of 15 patients with clonorchiasis, that were confirmed by stool examination and operation from May, 1976 to September, 1980. The results were as follows. 1) Filling defects due to adult worm of clonorchis sinensis were significant direct findings of clonorchiasis. 2) Irregular stenosis, fuzziness, raggedness, peripheral dilation and disturbance of peripheral filling of intrahepatic bile ducts were significant indirect findings of clonorchiasis. 3) ERCP was excellent method to evaluate biliary tree in patients with clonorchiasis, who showed obstructive jaundice.

Purpose: To evaluate the clinical symptoms of patients with dry eyes, based on the ocular surface disease index (OSDI) and analyze the relationship between OSDI and various ocular surface parameters. Methods: This was a retrospective study that included 45 eyes of 45 dry eye patients who visited the Seoul Nune Eye Hospital from August 2017 to December 2017. The patients were assessed by non-invasive keratography for the first break-up time, lipid layer thickness (LLT), tear osmolarity, tear matrix metalloproteinase-9 immunoassay as well as with the conventional Schirmer I test and fluorescein break-up time. The patient’s symptoms were evaluated by the OSDI questionnaires and correlations were analyzed based on the parameters described above. Results: There were significant negative correlations between OSDI and non-invasive keratography for the first break-up time (p = 0.038, r = -0.330), and LLT (p = 0.005, r = -0.426). However, there were no significant correlations between OSDI and fluorescein break-up time, Schirmer I score, and tear osmolarity (p = 0.173, 0.575, and 0.844 respectively). OSDI was not significantly different between matrix metalloproteinase-9 positive and negative groups (p = 0.768). Conclusions Non-invasive examinations such as non-invasive keratograph break-up time and interferometry of LLT can be efficient tools for evaluating dry eye symptoms.

Miyoshi myopathy is a rare distal myopathy of early adult onset and autosomal recessive inheritance. Weakness usually appears between 15 and 30 years of age starting from the posterior compartment of the legs. Serum creatine kinase (CK) level is characteristically elevated to 10- to 100-fold above the normal range. Muscle biopsy shows myopathic changes without vacuoles consistent with muscular dystrophy. It has not been reported in Korea as yet, so far as we know. We report a 23-year-old female who had the typical manifestations of Miyoshi myopathy with the brief review of literatures.

PURPOSE: The dancing eye syndrome is a rare neurological condition of unknown etiology characterized by multidirectional chaotic eye movement(opsoclonus), myoclons and ataxia. In children, it could be a paraneoplastic syndrome in association with neuroblastoma. Long-term neurological sequelae and decreased visual acuity are major problem in these patients. This study was done retrospectively to evaluate the clinical course and neurologic sequelae of the dancing eye syndrome and we also investigated in association with neuroblastoma. METHODS: We retrospectively reviewed the medical records of 5 childrens who were admitted to Pediatric Neurology, College of Medicine, Yonsei University for dancing eye syndrome from 1990 to 2001. RESULTS: The range of age was from 4 months to 2 years 9 months, 4 of them were female and the rest one was male. The mean follow up duration was 4 years 6 months. The associated diseases were hypoxic ischemic encephalopathy(2 cases), congenital aniridia(1 case). Neuroblastoma was identified in only 1 children, stage 2A. Four of them had recurrence of opsoclonus and visual acuity were getting worse(near blindness in 1 case). Four patients had a long-term neurological sequelae. The long-term neurological sequelae was dysarthria, learning disorder, seizure, ataxia. CONCLUSION: MIBG(Metaiodobenzylguanidine) scan and abdominal sonography are highly effective in the detection of neuroblastoma. Steroid therapy seems to be effective in opsoclonus in acute stage but did not necessarily have a good long term neurological outcome as it recurred. In conclusion, major problem in dancing eye syndrome is not opsoclonus and myoclonus in acute stage but decreased visual acuity and long-term neurological sequelae.

Objective: The Patient Health Questionnaire–9 (PHQ-9) and PHQ-2 have not been validated in the general Korean population. This study aimed to validate and identify the optimal cutoff scores of the PHQ-9 and PHQ-2 in screening for major depression in the general Korean population. Methods: We used data from 6,022 participants of the Korean Epidemiological Catchment Area Study for Psychiatric Disorders in 2011. Major depression was diagnosed according to the Korean Composite International Diagnostic Interview. Validity, reliability, and receiver operating characteristic curve analyses were performed using the results of the PHQ-9 and Euro Quality of life-5 dimension (EQ-5d). Results: Of the 6,022 participants, 150 were diagnosed with major depression (2.5%). Both PHQ-9 and PHQ-2 demonstrated relatively high reliability and their scores were highly correlated with the “anxiety/depression” score of the EQ-5d. The optimal cutoff score of the PHQ-9 was 5, with a sensitivity of 89.9%, specificity of 84.1%, positive predictive value (PPV) of 12.6%, negative predictive value (NPV) of 99.7%, positive likelihood ratio (LR+) of 5.6, and negative likelihood ratio (LR-) of 0.12. The optimal cutoff score of the PHQ-2 was 2, with a sensitivity of 85.3%, specificity of 83.2%, PPV of 11.6%, NPV of 99.5%, LR+ of 5.1, and LR- of 0.18. Conclusion The PHQ-9 and PHQ-2 are valid tools for screening major depression in the general Korean population, with suggested cutoff values of 5 and 2 points, respectively.

In cases of extropia with an exodeviation angle over 50 prism diopter (PD), a 3- or 4-muscle surgery is a rational option. But, in patients with sensory exotropia, there is usually a strong preference for a monocular procedure to avoid surgery on the single seeing eye. Thus, we confined surgery to visually poor eyes, and performed a medial rectus muscle resection with a mean of 10.3 mm (range, 9-11 mm) and a lateral rectus muscle recession with a mean of 12.8 mm (range, 10-14 mm) in 4 adult sensory exotropia patients who had a mean deviation of 82.3 PD (range, 75-90 PD). The mean postoperative angle of exodeviation was 2.0 PD (range, ortho-8 PD). The limitation on abduction was not disfiguring. Other expected disfigurements, such as narrowing of the palpebral fissure or enophthalmos, were not conspicuous. The mean follow-up period was 4.5 months (range, 3-7 months). In large-angle sensory exotropia, instead of additive surgery on the seeing eye, supermaximal medial rectus resection and lateral rectus recession only on the visually poor eye is a clinically feasible surgical option.

PURPOSE: To evaluate if at the time of diagnosis of Legg-Calve-Perthes disease, MR imaging is superior to radiographs for identifying patients with a favorable long term prognosis as determined by maintenance of a spherical configuration of the femoral head epiphysis on follow-up radiographs. MATERIALS AND METHODS: We retrospectively analyzed plain radiographs and MR images of 48 femoral heads in 41 patients with Legg-Calve-Perthes disease at time of diagnosis. Femoral head involvement was estimated on initial plain radiographs and MR images using the Catterall classification. Prognosis as determined by maximum femoral head deformity was determined on follow-up radiographs evaluated according to Stulberg classification. RESULTS: Catterall classification of greater than 1 at MR imaging had 100% sensitivity (14/14) for detecting patients with a poor prognosis as indicated by deformity of the femoral head on follow-up radiographs (Stulberg class > 2). Initial radiographs had a lower sensitivity of 57% (8/14) for detecting patients with poor prognosis. Specificity for MR imaging was 21% (7/34) which was not significantly different from 32% (11/34) specificity for initial radiographs. CONCLUSION: Catterall group 1 at initial MR imaging indicates favorable prognosis for Legg-Calve-Perthes disease. Patients with more extensive involvement of the femoral head can have a good outcome, however they are at risk for loss of spherical configuration of the femoral head and subsequent osteoarthritis in adulthood. MR imaging may be superior to radiographs for identifying a subgroup of patients with favorable prognosis.

BACKGROUND: pH measurement is an important test in assessing the etiology of pleurisy and in identifying complicated parapneumonic effusion. Although the blood gas analyzer is the' gold standard method' for pleural pH measurement, pH meter & pH strip methods are also used for this purpose interchangably. However, the correlation among the pH data measured by the three different methods needs to be evaluated. In this study, we measured the pH of pleural fluid with the three different methods respectively and evaluated the correlation among the measured data. METHODS: From August 1999 to March 2000, were measured the pleural fluid pH in 34 clinical samples with three methods-blood gas analyzer, pH meter, and pH strip. In the blood gas analyzer and pH meter methods, the temperature of plerual fluid was maintained around 0℃ in air-tight condition before analysis and measurement was performed within 30 minutes after collection. As for the pH strip method, the pleural fluid pH was checked in the ward immediately after tapping and in the clinical laboratory of our hospital. This part is unclear. RESULTS: The causes of pleural effusion were tuberculosis pleurisy in 16 cases, malignant pleural effusion 5 cases, parapneumonic effusion 9 cases, empyema 3 cases, and congestive heart failure 1 case. The pH of pleural fluid (mean±SD) was 7.34±0.12 with blood gas analyser, 7.52±0.25 with pH meter, 7.37±0.16 with pH strip of immediate measurement and 6.93±0.201 with pH strip of delayed measurement. The pH measured by delayed pH strip measurement was lower than those of other methods(p<0.05). The correlation of the results between the blood gas analyzer and pH meter(p=0.002, r=0.518) and the blood gas analyzer and pH strip of immediate measurement(p<0.001, r=0.607). CONCLUSION: In the determination of pH of pleural fluid, pH strip method could be a simple and reliable method under immediate measurement conditions after fluid tapping.
