  • The common carotid artery generally bifurcates into the internal and external carotid arteries at the level of C3-4. Injury to the common carotid artery during anterior cervical discectomy is a complication that is very much feared but encountered rarely. Knowing the anatomic variations of the common carotid artery and using an operating microscope during the anterior cervical approach for cases with low-lying bifurcation of the common carotid artery would prevent injuries to this artery. We present a 42-year-old female who has successfully undergone anterior cervical discectomy at the level of C5-6 and C6-7. She had a low-lying bifurcation of the common carotid artery.

  • During dissection of the saphenofemoral junction, anatomical variations in the tributaries of the long saphenous vein and external pudendal artery are frequently encountered, but the transpositions of the femoral artery and vein have very rarely been reported. On operation of the varicose vein, the surgical complications can be minimized when the possible deviations in the normal anatomy are taken into the consideration.

  • The variations of cleft lip deformities imposed the difficulty to the surgical correction for them. Straight line technique for cleft lip surgery has been ignored quite long since other techniques were developed. Initially the straight line technique was introduced and widely accepted because it is simple and easy to perform during the period of no adequate anesthetics. But it was abandoned for its several shortcomings such as tighten lip, vermilion notching, anatomical distortion, and wound contractures. Recently, some groups advocated the usefulness of straight line technique which has a significant modification from its original form. Additionally the variable degree of cleft lip deformity allows simple straight line closure for those patients. Here a case of simple straight line technique was presented and discussed for its reliability and plausible results as well.

  • In accordance with the growing up to a fine-built national physique on national economic rapid growth, It should be made a partial amendment on the Installation planing of sanitary ware. If users who regard have no problem as using facilities in a unisex toilet, It'll be not only falling down the separation of toilet booth with substantial sanitary problems step by step as follow. 1. The urinal should be pay due regard to such a shape which intercepts stream before the point of dispersion and variations in splash effects according to angles between stream and contact urinal surface with deferent of age and health of users 2. Urinal should be fit for the perineum height of male and so It could be install differently according to the Anatomical Percentile of users.

  • The radial artery is generally the preferred access route in coronary angiography and coronary intervention. However, small size, spasm, and anatomical variations concerning the radial artery are major limitations of transradial coronary intervention (TRI). We describe a successful case involving a patient with coronary artery disease who underwent TRI via a well-developed radial recurrent artery branch from the radioulnar alpha loop using a sheathless guiding catheter.

  • Anatomical variations of the sternocleidomastoid muscle (SCM) have been observed to occupy multiple origins and insertion points and have supernumerary heads, sometimes varying in thickness. During routine dissection, a SCM was observed to have six distinct insertions that interface with the course of the superior nuchal line, ending at the midline, bilaterally. This variation was also seen to receive innervation from the accessory nerve as well as the great auricular nerve. To our knowledge, this variant of supernumerary insertions and nerve innervations has not yet been reported. These variants may pose as problematic during surgical approaches to the upper neck and occiput, and should thus be appreciated by the clinician. Herein we discuss the case report, possible embryological origins, and the clinical significance of the observed variant SCM.

  • Antrolith occurs within the maxillary sinuses and is circumscribed pathologic calcifications formed as a result of mineral salt deposition around an organic nucleus in the maxillary sinus. Radiographically, this lesion is a radiopaque mass showing variable sizes and shapes. Treatment by surgical removal is indicated only for large antrolith associated to clinical symptoms. CBCT should be required for treatment planning for implant-supported restorations in the maxilla because of the higher prevalence of anatomical variations and sinus disease. We report a 3 cases of antrolith which was found incidentally on panoramic images and CBCT, although there were no clinical symptoms.

  • Chylothorax is caused by lymphatic leakage, which can develop after thoracic surgery and is associated with cancer. Although prospective randomized trials have not been performed, radiological interventions have been performed in several cases with persistent chylothorax, adjunct to 2 weeks of conservative management. The success rate of such interventions is diverse due to anatomical variations, although the results are promising. However, in cases of treatment failure after cycles of interventions, a team approach may be necessary to determine whether surgical management is warranted.

  • Radiation therapy (RT) is a very important treatment for cancer that irradiates a large amount of radiation to lead cancer cells and tissues to death. The progression of RT in the aspect of personalized medicine has greatly advanced over the past few decades in the field of technical precision responding anatomical characteristics of each patient. However, the consideration of biological heterogeneity that makes different effect in individual patients has not actually applied to clinical practice. There have been numerous discovery and validation of biomarkers that can be applied to improve the efficiency of radiotherapy, among which those related to genomic information are very promising developments. These genome-based biomarkers can be applied to identify patients who can benefit most from altering their therapeutic dose and to select the best chemotherapy improving sensitivity to radiotherapy. The genomics-based biomarkers in radiation oncology focus on mutational changes, particularly oncogenes and DNA damage response pathways. Although few have translated into clinically viable tools, there are many promising candidates in this field. In this review the prominent mutation-based biomarkers and their potential for clinical translation will be discussed.

  • Subsocial woodroaches of Cryptocercus occur in high mountainous forests in temperate regions and they live in a family in complicated galleries of rotten logs. A prominent feature of the geographical distribution of Cryptocercus is the wide disjunction between the eastern and western species in North America, and between West China and Northeast Asia. Recently, five species of the genus were added from Asian areas and two of them are distributed in Northeast Asian areas. We examined morpho-anatomical structures of male genitalia in Manchurian and Korean Cryptocercus, focusing on male genital hooks and subgenital plates.
