Identification of an individual is the mainstay of forensic investigation. In the present study, criteria for sex determination were established using 111 adult Korean sternums (63 males and 48 females). They were analyzed using identification points (IPs) and limit points (LPs), as reported previously. Only three of the ten parameters measured-sternal body length, sternal length (i.e., manubrium+body), and sternal area-were useful for sex determination, with sternal length being the most useful. The IP of sternal length was 147 and 130 mm for males and females, respectively. Using this parameter, 53.9% of males and 37.5% of females could be sexed with 100% accuracy. The LP was 141 mm for both males and females; sex could be discriminated accurately using this parameter in 85.7% of males and 85.4% of females

Leiomyoma is the most common benign tumor of the esophagus, but it still occurs rarely, as compared with the incidence of cacinoma. There are no geographic or racial differences and manifestations are unusual and inconsistent. About 97% of the esophageal leiomyoma may oecur in intramural type and 1 of the tumor may be polypoid type. Considerable diagnostic problems may arise as well as problems of proper surgical management. We experienced a case of a 47-year old female with esophageal leiomyoma in the mid- point of the esophagus. The patient complained of substernal discomfort for 1 month and routine examinatian and gastrofiberscope were performed. The gastrofiberscopic finding was asmoothly protruded, round bean-sized polypoid mass in the midpoint of the esophagus which was removed by polypectomy. There were no other complications. So we reported this case with review of literature.

The Peutz-Jeghers syndrome has three cardinal features: gastrointestinal polypasis, mucocutaneous piginentation and autosomal dominant heredity. This syndrome is ciinically important because of the complication caused by the gastrointestinal ployp, leading to abdominal pain, gastrointestinal bleeding and intussusception. We experienced a case of Peutz-Jeghers syndrome who complained of dizziness, vague abdominal pain, melanin pigmentations of the lips, oral mucosa and digits and reported with the review of the literature.

Corrected transposition of the great arteries is usually characterized by inverted ventricles and transposition of the great arteries. This combination without cardiac anormalies results in normal arterial oxigen content, hence the term corrected. Unfortunately, the condition rarely exists without other major cardiac anormalies. The authors report a case of situs inversus that was associated with corrected TGA, VSD, PS and ASD. The girl was admitted for evaluation of systolic ejection murmur on the both lower sternal border. Doppler echocardiography and cardiac angiography showed the diagnosis and so valvulotomy and closure operation of VSD and ASD was done.

BACKGROUND: There have been evidences that inactivation of tumor supressor genes such as p16 and pRb develops human malignancies. p16 inhibits the cyclin D/cyclin-dependant kinase 4 complex which phosphorylates pRb, thus negatively regulating cell cycle progression. Rb gene inactivation has been observed in various tumor and reported to be reciprocally correlated with p16 expression. The purpose of this study is to evaluate aberrant expression of p16 and pRb in acute leukemia by immunohistochemial stain in clot or biopsy section of the bone marrow. METHODS: For detection of p16 and pRb, immunohistochemical staining with anti-human mouse monoclonal antibodies to p16 and pRb were done on 62 bone marrow paraffin sections from leukemic patients. In acute lymphoblastic leukemia (ALL), immunophenotyping was performed with indirect immunofluorescent assay and clinical parameters were analyzed depending on status of p16 expression. RESULTS: In 28 cases (45%), abnormal expression of p16 or pRb were observed. Twenty three of those cases (37%) showed aberrancy only in one protein, in which case, staining intensity was generally more stronger than that of normal expression in both proteins. The proportion of abnormal p16 expression was 30% and 15%, and that of pRb was 30% and 36% in ALL and in acute myelocytic leukemia, respectively. There was no significant clinical correlation between aberrancy of p16 and clinical parameters of acute leukemia. CONCLUSION: Our results suggest that loss of the p16 and pRb function may contribute to pathogenesis of acute leukemia. Further study is needed in more cases of acute leukemia to evaluate clinical significance of p16 or pRb aberrancy, particularly in ALL.

Background:
Atomic bombs dropped on Hiroshima and Nagasaki in Japan in August 1945 were estimated to have killed approximately 70,000 Koreans. In Japan, studies on the health status and mortality of atomic bomb survivors compared with the non-exposed population have been conducted. However, there have been no studies related to the mortality of Korean atomic bomb survivors. Therefore, we aimed to study the cause of death of atomic bomb survivors compared to that of the general population.
Methods:
Of 2,299 atomic bomb survivors registered with the Korean Red Cross, 2,176 were included in the study. In the general population, the number of deaths by age group was calculated from 1992 to 2019, and 6,377,781 individuals were assessed. Causes of death were categorized according to the Korean Standard Classification of Diseases. To compare the proportional mortality between the two groups, the P value for the ratio test was confirmed, and the Cochran-Armitage trend test and χ 2 test were performed to determine the cause of death according to the distance from the hypocenter.
Results:
Diseases of the circulatory system were the most common cause of death (25.4%), followed by neoplasms (25.1%) and diseases of the respiratory system (10.6%) in atomic bomb survivors who died between 1992 and 2019. The proportional mortality associated with respiratory diseases, nervous system diseases, and other diseases among atomic bomb survivors was higher than that of the general population. Of the dead people between 1992 and 2019, the age at death of survivors who were exposed at a close distance was younger than those who were exposed at a greater distance.
Conclusion
Overall, proportional mortality of respiratory diseases and nervous system diseases was high in atomic bomb survivors, compared with the general population. Further studies on the health status of Korean atomic bomb survivors are needed.

Purpose:
For tonsillar cancer with multiple ipsilateral neck lymph nodes, the safety and efficacy of unilateral radiotherapy (RT) have long been a topic of debate. We performed retrospective analyses of patients having ipsilateral neck lymph nodes treated with unilateral RT in two tertiary referral hospitals.Material and Methods: This study accrued 29 patients who were diagnosed as well-lateralized tonsillar cancer with multiple ipsilateral neck lymph nodes and underwent unilateral RT from March 2000 to March 2020. Patients underwent treatment with one of the following options or a combination of them: induction chemotherapy, surgery, RT, and concurrent chemoradiotherapy. We analyzed the recurrence pattern and survival with special attention to contralateral neck failure. Also, treatment-related toxicities were compared with a 1:1 matched cohort of those who received bilateral RT, using propensity score matching analysis.
Results:
At a median follow-up of 68 months, no contralateral neck failure was observed. Five-year actuarial locoregional recurrence-free survival, distant metastasis-free survival, and overall survival were 85.6%, 91.8%, and 92.7%, respectively. Both the acute and chronic grade 2 xerostomia occurred in 10.3% of the patients. When the toxicity for unilateral RT was compared to that of bilateral RT using a propensity score-matched cohort, a significantly lower rate of acute xerostomia was observed in unilateral RT group (55.1% vs. 82.7%, p=0.002), primarily at grade 2 level (10.3% vs. 51.7%, respectively)
Conclusion
The results of our study suggest that unilateral RT can be safely performed in well-lateralized tonsillar cancer patients with multiple ipsilateral neck lymph nodes.
