  • Multiple primary cancer is defined as the discrete primary cancers in an individual originating in different sites or tissues. Billroth, in 1869, first reported the occurrence of different primary malignant cancers in the same patient. Because early diagnosis and treatment are key to good survival and cure rates, clinicians should be more aware of the possibility of multiple primary cancers in an individual patient with malignant tumor. The authors recently experienced a case of fifth primary cancer, their sites of origin were lung, glottis, lymph node, supraglottis, common bile duct. We report this case with a brief review of literatures.

  • Cementifyng fibroma is one of the fibro-osseous lesions. All fibro-osseous lesions containing cementum are considered to be of periodontal membrance origin and is most common in the maxilla and mandible. Rarely, cementifying fibromas are seen in other craniofacial bone except jaw lesion. A diligent search in the available world literature show only two documentation of cementifying fibroma in the fronto-orbital bone. This case is third case but first in the frontal bone beyond orbit. The authors report a case of cementifying fibroma of the frontal bone in 12-year-old female patient.

  • A common belief is that human milk is sterile. However, the development of culture-independent molecular methods, especially Next Generation Sequencing, has revealed that human milk harbors diverse and rich bacterial communities. Although studies aimed at characterizing the microbiota of human milk have produced different findings, Staphylococcus and Streptococcus are presumed to be normal members of the microbiota. Factors that influence variation in the microbiota are unclear; however, the postpartum time, route of delivery, maternal obesity, and health status may be influential. The origin of the microbiota is a hotly debated topic. Human milk bacteria are thought to be introduced through bacterial exposure of the mammary duct during breast feeding and/or the entero-mammary pathway from the maternal gastrointestinal tract. Although the exact mechanism related to the entero-mammary pathway is unknown, it is presumed that bacteria penetrate the intestinal epithelium and then migrate to the mammary gland, dendritic cells, and macrophages. In this review, various relevant studies are introduced.

  • Schwannomas are benign tumors of neuroectodermal origin and can be found in any part of the body. Although schwannomas are common in the head and neck region, they are rare in the auricle. Auricular schwannomas are rarely symptomatic but the mass itself or a surgical procedure to remove it may disrupt the complicated structure of the auricle. We report a rare case of auricular schwannoma with a literature review and describe the surgical technique used in this case.

  • Essential sources of arterial vascularisation in the head and neck region are the left and right common carotid arteries (CCA) and their branches. The left CCA (LCCA) originates from the arch of the aorta and the right CCA originates from the brachiocephalic trunk. In this case report, there was a bilateral higher division of CCA at the plane of the greater cornua of the hyoid bone, unilateral tri-ramification of the LCCA and the left external carotid artery (LECA), and the origin of the linguo-facial trunk and the pharyngo-occipital trunk from the LECA. An aneurysm formed in the distal part of LECA before its termination. In this case, we propose a novel categorization called the punnapatla classification for the anatomical variance branching forms of ECA. These kinds of variations are important to the surgeons, and anaesthetists, during the surgeries of the head and neck.

  • Three cores were taken from the northwest Pacific Ocean (Shikoku Basin) to determine the accumulation rates of both biogenic and terrigeneous fractions since the last penultimate interglacial period. The sediment is characterized by large amounts of terrigenous materials with low biogenic fractions and intermittent volcanic-ash layers, suggesting a hemipelagic origin. Composition of major elements shows no significant differences among sites. Relatively small variation of TiO$_2$/Al$_2$O$_3$ ratios with respect to SiO$_2$ content is the strong evidence for the common origin of terrigenous materials. The fraction of biogenic carbonates varies from near 0% in ash layers to about 35%, with a gradual increase toward the south (St. 4 through St. 6 to St. 20). However, carbonate contents show step-wise increasing tendency from St. 4 through St. 6 to St. 20, which suggests a southward increase of carbonate production. The color reflectance indicates that the sediment of the southern sites contains relatively higher amounts of biogenic carbonates. The mass accumulation rate of terrigenous fractions during the glacial period was 2-3 times higher than that of interglacial period. This enhanced mass accumulation rate of terrigenous materials was concomitant with the high accumulation rate of biogenic fractions. The total sediment accumulation rate is considered as the most important factor controlling mass accumulation rates of the biogenic and terrigenous materials. The enhanced sediment accumulation during the glacial periods is interpreted as a consequence of climate-induced change in the supply of eolian dust from the Asian continent. Enhanced wind strength during the glacial time may have increased transportation of terrigenous materials to the ocean. Thus, variation of sediment accumulation is highly linked with climatic variations.

  • We reviewed 45 cases of ovarian tumors treated at Seoul National University Children's Hospital from 1983 to 1993. Forty-five patients were operated upon for 52 ovarian tumors. The most common pathologic diagnosis was mature teratoma. The next were functional cyst, the tumors of epithelial cell origin, and those of stromal origin in order of frequency. Six patients(13%) had malignant tumor. There were one malignant teratoma, two dysgerminomas, one endodermal sinus tumor, and two granulosa cell tumors. Four cases were diagnosed as torsion of ovarian cyst preoperatively, and emergency exploratory laparotomy were performed. There were three cases of ovarian tumors associated with precocious puberty. The most widely used diagnostic tool was ultrasonography. In the treatment of these 45 patients, unilateral oophorectomy was done in 38 cases, unilateral oophorectomy with wedge resection of contralateral ovary was done in 5 cases, unilateral oophorectomy with contralateral simple cystectomy was done in one case and total abdominal hysterectomy with bilateral salpingooophorectomy was done in one case. Of the six cases of malignancy, five patients are alive 2 to 6 years after operation and one case was lost to be followed up.

  • Objectives : This paper contemplates how the special features found in Moyuan as revealed in Wenyilun has continued from the Moyuan concepts of past includig Huangdineinjing. The author of this paper attempted to distinguish common and different points between the two, and how these features changed in the following generations. Methods : The concept of Moyuan as revealed in Huangdineinjing is first reviewed before laying out the concepts of Moyuan in Wenyilun by different categories. These two concepts are then compared. A Chinese medicine literature database is used in continuing this study, and materials are selected with relation to the special features of Moyuan. Results : The special feature of half-exterior half-interior found in the Moyuan in Wenyilun is similar with that in Neijing in that they both thought Moyuan existed between the stomach, the lungs, and the five organs. The concealability of Moyuan is similar with the explanation of Moyuan in Suwen nuelun, and it is related with the story of Gaohuang in Chunqiu Zuozhuan. Compared to the fact that the concept of Moyuan in Neijing is explained as that pathogenic factor enters the surface of the body in sequence, the concept of Moyuan in Wenyilun is conveyed in that the pathogenic factor conceals itself first before being divided into exterior and interior. Moyuan is also related to upright qi, and Gaohuang-yuan: origin of Gaohuang, too, is connected Shenjiandongqi: the energy that moves between the two kidnets, and also the triple burner. Conclusions : The concepts of "Half-exterior Half-interior", concealability, and "divide it into several places in half-exterior", and upright qi contained within the Moyuan in Wenyilun are studied for their origins, and this effort is anticipated to be greatly helpful in both understanding the historical contexts of Wuyouke Wenyilun and conducting studies on clinical application of Moyuan theory.

  • Background: Acute lymphoblastic leukemia (ALL) is most common in childhood. Inhibin (a non-steroidal glycoprotein hormone of gonadal origin) can be used as marker of fertility. The current study was conducted to evaluate inhibin levels in ALL patients and to estimate its correlation with some antioxidants in these in comparison with control subjects. Materials and Methods: This study was conducted on sixty patients with ALL and thirty children as controls. Fasting blood samples were taken from each subject and analyzed for haemoglobin, serum protein, vitamin E and C, in addition to glutathione and inhibin. Results: The results of the study showed highly significant decreases (p<0.001) in haemoglobin, glutathione and inhibin levels with significant decreases (p<0.05) in serum protein and vitamin E levels for patients group in comparison with controls while there was no significant differences in vitamin C. Moreover, there were significant correlations between inhibin levels and serum protein, glutathione and both vitamins (E and C) in the ALL patient group (r= 0.81, 0.80, 0.77 and 0.69, respectively). Conclusions: The present results indicated infertility in patients with ALL demonstrated by low inhibin level as a consequence of abnormality in anti-oxidative metabolism due to the cancer process. So, it can be suggested the need for routine measurement of inhibin for leukemic patients to estimate the action of hormones of gonadal origin.
