Congenital absence of the pericardium, also known as pericardial agenesis, is an extremely rare anomaly. Although most cases are asymptomatic, some experience chest pain, dyspnea, dizziness, and syncope. A few sudden death cases have been reported. We report a case of congenital complete left-sided absence of the pericardium that is not related to the cause of death. In the autopsy of a skinny 45-year-old deceased man, there was no left pericardium, and the heart had direct contact with the left lung. Inflammation and adhesion around the heart, torsion of great vessels, structure abnormality of the heart, and histologic lesion of the myocardium were absent. Due to the chemical analysis result and morphology, we suspected that the cause of death was related to starvation. The congenital absence of the pericardium is usually accompanied by myocardial infarction, aortic dissection, and variable congenital anomalies in the heart and other organs. Additionally, both complete and partial defects can cause myocardial infarction. Therefore, we suggest that precise gross examination should be performed to determine the ischemic lesions in the heart and other anomalies if congenital absence of the pericardium is noted in the autopsy.

Estimation of the minimum post-mortem interval (PMI-min) by means of forensic entomology is mainly based on the results of the growth rate studies on necrophagous flies. However, results of these studies are difficult to use because these studies have only been undertaken for a select few necrophagous flies, and experimental methods and results processing have not been standardized. In this review, we have summarized the current state of growth rate studies on necrophagous fly species that are frequently found in human cadavers. Criteria have been suggested in order to select reliable data, and the accumulated degree hours and base temperatures to be used in the calculation of PMI-min for each species have been tabulated.

PURPOSE: To evaluate mortality and morbidity of very low birth weight infants(VLBW infants) born in the Busan area from 1996 to 2005. METHODS: A total of eight neonatal intensive care units (4 university hospitals and 4 general hospitals) in Busan participated in this study. A total of 1,414 VLBW infants were divided into three groups: period I, 1996 to 2000; period II, 1999 to 2002; period III, 2003 to 2005, based on date of birth. We performed a retrospective review of medical records of VLBWinfants and compared the survival rate, morbidity and mortality over the three periods. RESULT: The number of VLBW infants admitted to 8 NICUs in 1996-2005 was a total of 1,414 (1.3% incidence, mean gestational age 29.1+/-2.7 wk, mean birth weight 1158+/-235 g), including 361 (24.7%) extremely low birth weight infants (ELVW infants) who were less than 1,000 g at birth weight. Overall survival rate of VLBW infants was 66.1%. The survival rate of VLBW infants increased significantly over the three periods (period I:57.6%, period II:67.8%, period III:75.7%, P<0.01). Overall survival rate of ELBW infants was 33.8%, and increased from 26.4% in period I to 44.2% in period III (P<0.01). The incidence of respiratory distress syndrome was 45.1%; patent ductus arteriosus, 16.4%; bronchopulmonary dysplasia, 13.1%; blood culture positive sepsis, 12.7%; necrotizing enterocolitis, 6.6%; severe intracranial hemorrhage, 6.5%; and severe retinopathy of prematurity, 5.9%. The main causes of death were respiratory distress syndrome and sepsis. CONCLUSION: Overall survival rate of very low birth weight infant in Busan area during the last 10 years was 66.1%, and increased significantly over the three periods.

Mucinous borderline tumors (MBT) of the ovary with mild to moderately atypical epithelial cells that produce mucin rarely recur and very rarely become malignant after surgery. Due to their low malignant potential and large tumor size, most cases are diagnosed in stage I and have a good prognosis. The authors reported a case of MBT, which had been left untreated after diagnosis, progressed to stage IV, and caused massive pleural effusion (>3,000 mL) resulting in death. Grossly, severe abdominal swelling, a huge multiloculated cystic mass in the left ovary, and a metastatic mucinous mass in the pleura and peritoneum were observed. Histological findings include gastrointestinal type epithelial cells with mucin secretion, degenerative and autolytic nuclei, and occasional infiltration of inflammatory cells. Because sufficient sections cannot be made according to the clinical pathology criteria in forensic autopsy, efficient decisions are required during autopsy for diagnosis.
