Catecholamine-induced cardiomyopathy associated with neuroblastoma is rarely reported. We report a case of catecholamine-induced cardiomyopathy associated with neuroblastoma in a 33-month-old female that was treated with extracorporeal membrane oxygenation (ECMO). She was tentatively diagnosed with acute myocarditis and presented with hypertension. Because of rapid patient deterioration despite pharmacological treatments, ECMO was applied. ECMO can be helpful in cases of catecholamine-induced cardiomyopathy associated with neuroblastoma.

2.Relationship between Middle school Students' Computer using Time and Dry eye.
Journal of the Korean Ophthalmological Society 2002;43(3):449-454
PURPOSE: As computer and Internet are getting widely spread, people who use visual display terminal (VDT) are increasing. Especially as computer and Internet on line games are popular, more people are exposed to VDT than in the past. So we examined to explore the relationship between middle school students' computer using time and dry eye. METHODS: The subjects were 105 middle school male students in the same district. We surveyed them on the time of computer use weekly and ocular discomfort while using computer. We examined anterior segment of the eyes by slit lamp, and checked BUT and Shirmer test. RESULTS: The subjects who frequently use computer showed shorter BUT, dry eye related ocular findings (meniscus floater, corneal erosion.), and symptoms of dry eye. But there was no significant difference in Schirmer test. CONCLUSIONS: Students in middle school age may have symptoms and ocular findings of dry eye owing to increased time of computer use. So proper rest during computer use and adequate education for dry eye are thought to be necessary.

We evaluated the distribution of normal conjuctival flora and the change of antibiotic sensitivity of cultured bacteria. Specimens were obtained from inferior conjunctiva cul de sac with sterile cotton-tipped applicator from healthy 216 human beings. Antibiotic sensitivity test was done by disk diffusion method. The results indicated that overall positive culture rate was 47.7% and major organisms were Coagulase-negative Staphylococcus(55.7%), Staphylococcus aureus(16%), Gram negative bacteria(7.5%), Streptococcus(4.7%). Antibiotic sensitivity test of cultured Gram positive bacteria demonstrated less than 60% rate of susceptability in gentamicin, tetracyclin, erythromycin and 80.5% rate of susceptability in ciprofloxacin. Gram negative bacteria demonstrated less than 60% rate of susceptability in cephalothin, ampicillin. From the above results, we concluded that antibiotic resistance of normal conjunctival flora was increased from the past and the principle of antiviotic eye drop use should be emphasized.

The spinal cord is a complex and densely packed structure of nerve tissue, and magnetic resonance imaging (MRI) is an excellent imaging modality for evaluating its pathologies. Among the distinct functional zones of the spinal cord, the dorsal (or posterior) column is a crucial white matter region responsible for transmitting sensory information and is located in the posterior aspect of the spinal cord. Myelopathies of the dorsal column typically appear as high signal intensity in this region on T2-weighted images. They may arise from several pathological processes, including degenerative, metabolic, inflammatory, infectious, and traumatic conditions. Identifying the specific etiology through characteristic MRI features, along with the patient’s clinical presentation, is crucial for developing an effective treatment plan and understanding the prognosis of sensory abnormalities. This study reviews myelopathies that specifically affect the dorsal column and outlines the MRI findings that aid in the differential diagnosis of these dorsal column lesions.

Background:
This study aimed to evaluate the relationship between clinical experience and death certificate (DC) errors by analyzing DCs written by experienced emergency physicians (EPs).
Methods:
DCs issued by four experienced EPs over a 10-year period were retrospectively reviewed. DC errors were divided into major and minor errors based on whether they affected the cause of death (COD) determination. The errors were judged through first and second evaluations. Basic information regarding DCs and 10-year changes in DC errors were analyzed.
Results:
A total of 505 DCs were analyzed, with an average of 34 to 70 for each study year.The number of CODs written in the DCs tended to decrease over time. The presentation of major DC errors did not show a tendency to change over time. However, the sum of the major and minor errors tended to increase over time. Secondary conditions as the underlying COD tended to increase, and the incompatible causal relationships between CODs tended to decrease over time in the detailed analysis of major errors. The increasing tendency for incorrect other significant conditions, incorrect type of accident, incorrect intention of the external cause, no record of the trauma mechanism, and record of the trauma mechanism without another COD were found in the detailed analysis of minor errors.
Conclusion
DC errors did not decrease as clinical experience increased. Education to reduce DC errors and a feedback process for written DCs are necessary, regardless of clinical experience.

Coronary restenosis is still regarded as Achilles' Hill of interventional cardiology despite relentless efforts of many investigators. Recent experimental and clinical studies have suggested that both gamma and beta radiation can be reduce restenosis after angioplasty. Currently, intracoronary brachytherapy for the prevention of restenosis has become a new evolving treatment modality in interventional cardiology. This report discusses a physical aspect of gamma and beta radiation, initial clinical results and delivery systems used in intracoronary brachytherapy. We shall take a brief overview of methods and their advantages in intracoronary brachytherapy. Future work should provide further insight for the best way of treating restenosis.

Objective/BACKGROUND: Serum levels of anti-acetylcholine receptor antibody (AChR-Ab), interleukin-2 (IL-2) and soluble interleukin-2 receptor (sIL-2R) may represent markers of disease severity in myasthenia gravis (MG). This study was performed to evaluate the correlations between disease severity and immunological parameters such as serum AChR-Ab, IL-2 and sIL-2R level and between each immunological parameters. METHODS: Serum levels of AChR-Ab, IL-2 and sIL-2R were measured in 30 MG patients and in 22 healthy controls. Results : Serum levels of AChR-Ab and sIL-2R were higher in MG than in healthy controls (p<0,01). The occurrence of IL-2 positive serum samples was 46.7% in MG but none in controls. There were no significant correlations between disease severity and immunological parameters and between each immunological parameters. Conclusions : Serum IL-2 and sIL-2R levels may not represent markers of disease severity in MG, In order to further document the correlation between each parameters, follow-up of individual patients with serial serum samplings may be necessary.

BACKGROUND AND OBJECTIVES: Tympanosclerosis is a nonspecific and irreversible result of chronic inflammation or infection of the middle ear. However, there remains disagreement about how best to surgically treat tympanosclerotic ossicular fixation, with the controversy over its management when stapes is involved. The aim of this study was to evaluate operative findings and hearing results of tympanosclerosis involving the ossicular chain, which in turn would establish better surgical treatment of tympanosclerotic ossicular fixation. SUBJECTS AND METHODS: In this prospective study conducted from Mar 2000 to Dec 2007, 38 patients with tympanosclerosis who had undergone surgical treatment were evaluated. The clinical and operational records and pre- and postoperative pure tone audiograms were reviewed. RESULTS: Operative findings showed stapes fixation is the most common. In 8 patients (21.1%), stapes was mobile, while, in the remaining 30 patients (78.9%), stapes fixation was found. In all cases with stapes fixation, stapes mobilization was possible. Following hearing result reporting guideline by the Korean Otological Society, the success rate of middle ear surgery was 68.4% (26 of 38 patients). In cases with stapes fixation, the success rate was 66.6% (20 of 30 patients), while, in cases with no stapes fixation, the success rate was 75.0% (6 of 8 patients). However, there was no statistical significance between the two groups. CONCLUSION: Stapes fixation was found in 78.9% of tympanosclerotic ossicular fixation. In management of tympanosclerotic stapes fixation, meticulous excision of tympanosclerotic plaques and removal of new bone formation around stapes footplate after adequate exposure could achieve a relatively good hearing result without stapes surgery.
