The 45 neonates with bronchopulmonary dysplasia among 355 neonates who were managed with mechanical ventilation and oxygen therapy in NICU of Seoul National University Chhildren's Hospital from January 1, 1968 to December 31, 1991, were analyzed for risk factors and outcome. The results were as follows: 1) The incidence of bronchopulmonary dysplasia was 12.7% 2) Respiratory Distress Syndrome was most common underlying problem. 3) The common radiologic findings of BPD were peripheral streaky density, emphysematous change, reticular or granular perihilar density, pulmonary interstitial emphysema, bubbly or small cystic change, and pneumothorax. 4) The survival rate of BPD showed 80% in the follow-up study. 5) Retinopathy of prematurity and intraventricular hemorrhage were more frequent significantly in the BPD group (p<0.05). 6) The risk factors of BPD were lower birth weight, shorter gestational age, longer duration of oxygen therapy an mechanical ventilation, and the presence of PDA.

Rhabdomyoma is the most common fetal cardiac tumor, and its development is related to tuberous sclerosis. Fetal cardiac rhabdomyomas often spontaneously regress in utero or after birth, but large tumors can cause hemodynamic obstruction. Sirolimus, a mammalian target of rapamycin (mTOR) inhibitor, has been used as an immunosuppressant after organ transplantation. The mTOR inhibitors are well-known to have anti-tumor activity, and they have been used for the treatment of patients with tuberous sclerosis. In the current case, fetal cardiac rhabdomyoma was completely resolved in utero during oral sirolimus treatment in the mother with tuberous sclerosis. This case shows that oral sirolimus therapy in pregnancy may be a treatment for multiple or large fetal cardiac rhabdomyomas.

PURPOSE: To evaluate histopathologic correlation of the component of the lesion on CT and MR of retinoblastomas. MATERIALS AND METHODS: Gross pathologic findings of 24 enucleated eyeballs in 24 patients with retinoblastomas were compared with preoperative CT (n=19) and MR (n=5) findings. In eight eyeballs, in which there were findings other than mass, histopathologic findings were reviewed and correlated with image findings. RESULTS: Retinal detachment and subretinal hemorrhage which were not detected on CT were demonstrated in two of eight eyeballs on histopathologic examination. In one eyeball, retinal detachment and subretinal effusion were detected on both CT and in a pathologic specimen. In two eyeballs with peripheral heterogeneous MR enhancement of the masses, tumor necrosis and calcification were demonstrated in the central non-enhancing portion of the mass. In two eyeballs, linear soft tissue along the retina apart from the main mass were revealed as tumor spread along the retinal surface. In one patient, retinal thickening on MR was presumed to be an MR artifact and no lesion was found in the gross specimen. CONCLUSION: On CT, retinal detachment and subretinal hemorrhage associated with retinoblastoma can mimic mass, and tumor spread along the retinal surface can be seen as a linear retinal lesion. On MR, tumor necrosis and calcification can be a cause of heterogeneous enhancement.

BACKGROUND: Drowning represents the third most common cause of all accidental deaths worldwide. Although few studies of submersion injury were done in Korea, the subjects were mainly pediatric patients. The purpose of this study is to describe the clinical feature of submersion injury in adults. METHODS: The medical records of 31 patients with submersion injury who were >15 years of age and admitted to Kyungpook National University Hospital from July 1990 to March 2003 were retrospectively examined. RESULTS: The most common age-group, cause, and site of submersion accidents in adults were 15-24 years of age, inability to swim, and river followed by more than 65 years of age, drinking, and public bath respectively. The initial chest radiographs showed bilaterally and centrally predominant distribution of pulmonary edema at lung base in about 90% of patients with pulmonary edema represented by submersion injury but at only upper lung zone in 10%. Eventually, 25 patients (80.6%) survived without any neurologic deficit and 2 patients (6.5%) with significant neurologic deficit, and 4 patients (12.9%) died. Age, arterial gas oxygenation, and mental status among baseline variables showed significant difference for prognosis. CONCLUSIONS: More than 65 years of age, drinking, and occurrence in public bath were relatively important in submersion injury of adults, and the successful survival of 80.6% of patients suggests that cardiopulmonary resuscitation should be intensively done in even adults.

OBJECTIVES: X-rays are widely used in medical examinations. In particular, chest X-rays are the most frequent imaging test. However, observations are usually recorded in a free-text format. Therefore, it is difficult to standardize the information provided to construct a database for the sharing of clinical data. Here, we describe a simple X-ray observation entry system that can interlock with an electronic medical record system. METHODS: We investigated common diagnosis indices. Based on the indices, we have designed an entry system which consists of 5 parts: 1) patient lists, 2) image selection, 3) diagnosis result entry, 4) image view, and 5) main menu. The X-ray observation results can be extracted in an Excel format. RESULTS: The usefulness of the proposed system was assessed in a study using over 500 patients' chest X-ray images. The data was readily extracted in a format that allowed convenient assessment. CONCLUSIONS: We proposed the chest X-ray observation entry system. The proposed X-ray observation system, which can be linked with an electronic medical record system, allows easy extraction of standardized clinical information to construct a database. However, the proposed entry system is limited to chest X-rays and it is impossible to interpret the semantic information. Therefore, further research into domains using other interpretation methods is required.
