Choriocarcinoma associated with a normal pregnancy is rare. Futhermore, choriocarcinoma coexistent with a viable pregnancy is even rarer and associated with a greater risk of hepatic and cerebral involvement. So timely diagnosis of the disease is important for successful treatment and aggressive diagnostic procedures may therefore warranted. The patient should be treated with primary intensive combination chemotherapy(EMA-CO) and the selective use of irradiation and surgical therapy. We experienced a case of metastatic choriocarcinoma of lung and kidney following preterm delivery at 34th week of pregnancy and so present it with brief review of literature.

Aortopulmonary septal defect is a rare congenital cardiac anomaly. A 15 year old boy was admitted to Department of Internal Medicine of Seoul National University Hospital because of exertional dyspnea. Aortopulmonary septal defect was confirmed by cardiac catheterization demonstrating severe pulmonary hypertension and patent foramen ovale, and retrograde aortogram showing contrast material passing from the ascending aorta just above the aortic valve into the pulmonary trunk. We present a case of aortopulmonary septal defect with a review of literatures.

The purpose of this study was to investigate utilization and storage management practice of the frozen and refrigerated foods in school foodservice. 222 dietitians employed in school foodservice were surveyed. In school foodservice, the refrigerated stock farm products and seafoods (78.3%) were more used rather than frozen products (47.5%). According to school foodservice characteristics, the refrigerated meats including dairy products were more frequently used in elementary and middle schools than high school foodservice. On the other hand, the foodservice in high school used more frozen seafoods and processed foods than elementary school did. The data also showed a tendency for the contracted foodservice using more frozen meats and seafoods rather than refrigerated products when comparing with the self-operated foodservice. In terms of receiving conditions, storage methods and storage time, the result indicated that frozen or refrigerated products were often delivered at inappropriate temperature. Especially some products which were needed to be shipped and stored at refrigerated temperature such as mollusks, were delivered and kept at room temperature. The most frequently used thawing method were running water (56.9%), however, the frozen products were often sitted at room temperature for the purpose of thawing. According to the results, several inappropriate handling processes for frozen and refrigerated products were found in school foodservice. In order to improve handling process for frozen and refrigerated products, recognition of food handlers' weakness about storage and distribution, development of radical standards for receiving conditions, storage and thawing methods should be debated.

The recent debate surrounding the expansion of enrollment in Korean medical schools has reignited interest in the Flexner Report, published in the United States in 1910. Historically, medical education in the United States transitioned from small proprietary schools to university-affiliated institutions, emphasizing basic science and clinical experience. The Flexner Report advocated for scientific medicine and led to significant reforms in medical education, including standardization of curricula and strengthened admission requirements. The influence of this report extended to Korean medical education, shaping its curriculum, accreditation system, and emphasis on academic excellence. The expansion of medical school enrollment has led to a crucial dilemma. Should we prioritize the training of physicians who provide practical medical services or continue to emphasize academic medicine as we do now? There has been insufficient discussion of the individualized curricula, necessary investments, and societal efforts to accommodate these changes. It is imperative to move beyond mere enrollment expansion debates and collectively determine the future trajectory of Korean medical education, devising actionable plans to achieve overarching goals.

BACKGROUND: The cardiac troponin I (cTnI), one of the subunits of the troponin regulatory complex, binds to actin and inhibits interactions between actin and myosin. cTnI is highly sensitive and specific marker for myocardial injury and is useful in diagnosis and detection of reperfusion in acute myocardial infarction (AMI). In this study, we measured the serum concentration of cTnI according to serial time after chest pain in patients with AMI and compared serum concentration of cTnI with CK-MB and echocardiographic data to evaluate the significance of measuring serum concentration of cTnI in AMI. SUBJECTS AND METHODS: The study was carried out on 16 patients with first attack of AMI within 6 hours of chest pain. All patients were performed thrombolytic therapy and reperfusion was confirmed by coronary angiography. Blood samples for measuring of CK-MB and cTnI were collected at 4-h intervals during the first 24 h, 12-h intervals until 48 h, and 24-h intervals until fourth days after hospitalization. Echocardiography were performed before thrombolytic therapy in all patients. RESULTS: 1) The mean age of subjects was 63.6+/-11.5 years (range:44 - 84 years) and 11 patients were men and 5 patients were women. The site of infarction was anterior in 11 patients and inferior in 5 patients. 2) The peak concentrations of CK-MB and cTnI were reached from 4-h to 12-h after admission in all patients (7.3+/-2.6-h, and 9.0+/-3.1-h, respectively), but there was no significant difference in peak time. 3) Serum concentration of CK-MB was normalized at 72-h after admission, but cTnI was remained in increased state until 96-h after admission. The numbers of the patients with above cutoff value of CK-MB and cTnI at different time after admission were significantly different after 72-h (p<0.05). 4) The peak cTnI and sigma cTnI level were significantly correlated with peak CK-MB and sigma CK-MB level, respectively (r 2 =0.7955, p<0.0001 and r 2 =0.6378, p=0.0002, respectively). 5) The ejection fraction was not correlated with peak cTnI concentration (r 2 =0.0948, p=0.2461) and sigma cTnI (r 2 =0.1867, p=0.0946). 6) The wall motion score index was not correlated with peak cTnI concentration (r 2 =0.2135, p=0.0716), but significantly correlated with sigma cTnI (r 2 =0.2540, p=0.0465). CONCLUSION: The serum concentration of cTnI was useful in late diagnosis of AMI and cTnI release in patients with AMI was correlated with myocardial infarct size.

STUDY DESIGN: A retrospective study. OBJECTIVE: To compare the peri-operative morbidity of patients who undergo same-day operations for lumbar spinal stenosis accompanied by severe osteoarthritis of knee with those who undergo staged operations . SUMMARY AND LITERATURE REVIEW: There is no report on the peri-operative morbidity of same-day operations for patients who have a concurrent lumbar spinal stenosis and severe osteoarthritis of the knee, even though elective surgery for lumbar spinal stenosis or total knee arthroplasty are safe procedures. MATERIALS AND METHODS: From January 1996 to December 2005, 11 patients who underwent staged operations for lumbar spinal stenosis and concomitant osteoarthritis of the knee (Group I) and 14 patients who underwent total knee arthroplasty and lumbar spinal decompression and fusion on the same-day (Group II) were compared in terms of the operative time, blood loss, perioperative complications and admission days. The data was analyzed statistically using a chi-square test through SPSS v.10.0. RESULTS: The mean surgery time in groups I and II was 266+/-34.4 minutes and 258+/-54.2 minutes, respectively. The estimated blood loss during operation of groups I and II was 1055+/-229.6 and 925+/-174.0. There was no statistical differences between the two groups. There were no life-threatening complications in any group. The admission period for group I and group II were 41.0+/-6.05 days and 30.1+/-5.10 days respectively, but there was no statistical significance. CONCLUSION: There was no difference in the surgical time, estimated blood loss, and complications between the group that underwent the staged operations and the group that underwent same-day operations. A possible surgical option is to perform both procedures on the same day.
