  • In 1995, the American Association of Physicists in Medicine (AAPM) Task Group 43 published a report dealing with the dosimetry of interstitial brachytherapy sources, generally known as the TG-43 report. Compared to previously adopted formalisms, a formalism proposed in this report provides a more accurate and systematic brachytherapy dose calculation method, especially for Ir-192 and other low energy gamma sources such as 1-125 and Pd-l03. In this lecture, an overview of the TG-43 formalism will be presented, along with the lecturer's experience in determining the TG-43 parameters by the Monte Carlo method and experimental methods such as TLD and radiochromic film.

  • Purpose: The cutaneous squamous cell carcinoma is the second most common skin malignancy. It is noted that keratoacanthoma is difficult to differentiate from squamous cell carcinoma, clinically or historically. It is still a hypothetical question whether keratoacanthoma is a pseudomalignancy or a form of squamous cell carcinoma. Methods: We report the case of squamous cell carcinoma around left ala of nose in a 64-year-old female patient. Through an incisional biopsy, the mass was found to be keratoacanthoma in the pathologic report. An excisional biopsy was performed. Results: Pathologic report notified that it was found well-differentiated squamous cell carcinoma arising in keratoacanthoma with focal involvement of deep resection margin. Wide excision was made with 0.5-1.5 cm margin and immediate reconstruction was performed. Conclusion: The relationship between keratoacanthoma and squamous cell carcinoma has been debated in the treatment. It is still controversial whether to excise it or not. We concluded that kerathoacanthoma must be removed completely.

  • Purpose: This study was to explore gender differences on presenting patients with acute myocardial infarction in the emergency department. Methods: The survey was done with 143 emergency medical charts presented to the emergency department and diagnosed with acute myocardial infarction between January 2005 and December 2006. The collected data were analyzed with frequency, chi-square, and t-test. Results: Significant gender differences were apparent in age, route to the emergency department, elapsed time from onset of symptoms to arrival, and initial heart rate. Women were significantly more likely to report hypertension, diabetes, and congestive heart failure than men, but men were significantly more likely to report smoking. Chest pain was the most common initial symptom in both men and women. Women were significantly more likely to report dyspnea and nausea/vomiting than men. Conclusion: Although similarities exist in the associated symptoms of acute myocardial infarction, women might experience different symptoms, compared to men. These findings have implication that patients and health care providers should consider gender difference in presenting symptoms.

  • Motion of the metatarsophalangeal joints is essential for the normal gait. Therefore it is important to recover the motion of normal joint in the treatment of stiffness of the metatarsophalangeal joints. However, there have been no report about the treatment of stiffness of the four lateral lesser metatarsophalangeal joints yet. We report an experience that good clinical and radiographic results were obtained after resection arthroplasty for the post-traumatic stiffness of the four lateral lesser metatarsophalangeal joints.

  • Innominate artery aneurysms are challenging for surgeons to treat because of the requirement for brain protection during surgery. In innominate artery aneurysms, the endovascular approach does not require cardiopulmonary bypass, but patients who can be treated using this approach are limited in number, and the long-term results of endovascular treatment are unclear. Here, we report our experience of successfully treating a patient with an innominate artery aneurysm using near-infrared spectroscopy without cardiopulmonary bypass support or hypothermic circulatory arrest.

  • Osseous metaplasia is defined as the formation of lamellar bone inside soft tissue structures where bone normally does not exist. It results from the transformation of non-osseous connective tissue into mature bone. This condition is rare in the oral and maxillofacial region. We report a case of osseous metaplasia of the maxilla, a rare benign tumor in an uncommon region. A 60-year-old male patient visited our clinic complaining of foreign body sensation and asymptomatic swelling on the right palatal side. However, he did not experience pain and reported no local trauma that he could remember. Intra-oral examination revealed an exophytic lesion on the right palatal portion. On computed tomography, there was a round hard-tissue mass approximately 2 cm in diameter on the right palate area. The mass was biopsied and diagnosed as an osseous metaplasia. We review the clinical, radiographic, and histologic features and common causes of osseous metaplasia and report a rare case of osseous metaplasia of the palate.

  • Pleuropulmonary blastoma is a rare malignant neoplasm which originates from either the lungs or pleura. Pleuropulmonary blastoma usually develops in the first decade of life, mostly younger than 5 years old and shows aggressive biological behavior. Pleuropulmonary blastoma is discriminated from classic pulmonary blastoma of adulthood by its morphological features like primitive mesenchymal and sarcomatous component without carcinomatous portions. To our knowledge, report of pleuropulmonary blastoma in adulthood is very rare. Our case support the possibility that primitive neoplasm recognized as pediatric tumors can develop in adulthood. We report a case of surgical experience of pleuropulmonary blastoma which developed in 21 years old man with literature review.

  • Purpose: Heterotopic ossification in pressure sore patients is reported to rarely develop, but once it occurs, it frequently causes joint stiffness and mobilization restriction. The aim of this article is to report our experience of atypical bone growing at femur neck fracture site with chronic, extensive pressure sore in patient with paraplegia secondary to spinal injury. Methods: A 28-year-old male patient presented with atypical bone growth at femur neck fracture site with pressure sore. He had undergone atypical growth bone removal and separation of united iliac bone and femur, and then pressure sore was covered by advanced rotation flap. Results: The patient mobilized hip joint and rode in a wheelchair. Complications such as dehiscence, infection, hematoma and flap necrosis did not occur. Conclusion: We experienced successful correction of atypical bone growth removal and recovery of pressure sore. We report our experience of atypical bone growth of fracture site and the related literature was reviewed.

  • Negative experience related to work-family multiple roles has been associated with internalizing problems in mothers. In particular, employed mothers with preschool children report high degree of stress. As such, the need to examine potential factors that may explain and alleviate such difficulties has been emphasized. The purpose of this study was thus to examine the mediating effect of sociotropy on the relationship between negative work-family multiple roles and internalizing problems in employed mothers with preschool children. The Negative Experience of Work-Family Multiple Roles Scale, Adult Self Report (ASR) Scale, and Personal Style Inventory-II (PSI-II), were completed by 208 employed mothers with preschool children through an online survey. The results indicated that the direct effect of negative experience of work-family multiple roles on internalizing problems was statistically significant and the indirect effect of sociotropy in this relationship was significant. These findings suggest that sociotropy in employed mothers may indirectly explain internalizing problems related to multiple roles. The implications of sociotropy in negative experience of work-family multiple roles and internalizing problems are discussed.
