Histology and histopathological knowledge are the basis for clinching an appropriate diagnosis. The characteristic features presented by tumours or tumour like conditions have a distinct picture of their own, and can be distinguished if viewed with an eagle’s eye. The aim of this review is to take an appearanceoriented approach for ease of correlation with day to day objects and thus helping in mastering the art of diagnosis. This paper aims to provide a single, concise source of recognition for majority of head and neck tumours or tumour like conditions. Review emphasises on radiologic and histopathologic appearances. © This is an open access article distributed under the terms of the Creative Commons Attribution License (https://creativecommons.org/licenses/by/4.0/) which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.

Hepatitis B virus transmission in a dental setting more commonly occurs due to inadequate/improper use of safety measures by the dentist. This particular study evaluated the hepatitis B virus infection related awareness among dental graduates. A validated questionnaire regarding the awareness about hepatitis infection and various infection control measures was distributed among the students of different year of study in undergraduate bachelor dental graduate program. Final year students showed an increased awareness when compared to third year students. There is need for improving the knowledge among the nonclinical students, mainly on transmission of virus through salivary contact. The overall awareness among the students is only fairly satisfying, which signifies the need for continued infection control education among the students. © 2020 Published by Innovative Publication.

Inappropriate identification of a patient with a compromising systemic condition through improper history taking and interpretation, can create ineffective, or may be detrimental treatment. We frequently describe a dental treatment plan for a person with a compromising systemic condition as a compromised plan because the dental treatment might not be ideal in comparison to the treatment provided to a person who doesn’t have any disabling condition. We are presenting a case of bilateral parasymphysis fracture of the mandible with multiple impacted teeth in an 18 year old mentally challenged medically compromised male. © 2020 Published by Innovative Publication.

Pathogenesis and detection of micrometastasis in OSCC- An overview OSCC微转移的发病机制及检测综述

Journal of oral medicine

Pub Date : 2020-10-28 DOI: 10.18231/J.JOOO.2020.031

Oral squamous cell carcinoma (OSCC) has a remarkable global incidence and equally daunting mortality rates. Despite diagnostic and therapeutic advancements, mortality and morbidity rates in patients diagnosed with oral cancer remain constant. The most fundamental prognostic marker for patients with OSCC is metastasis to cervical lymph nodes or distant organs. Micrometastasis refers to the microscopic deposits of malignant cells distinct from the primary lesion. There are several techniques for detection of micrometastasis including Immunohistochemistry (IHC), Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) and serial sectioning but certain special stains that are reliable like Modified Papanicolaou stain and Toluidine can be used on serial sectioned lymph node sections to detect micrometastasis. Early recognition of micrometastatsis in OSCC especially after surgery is undeniably advantageous for the patient and aids in modifying the treatment. Micrometastasis being an essential adverse prognostic factor in oral and oropharyngeal SCC, it becomes the utmost responsibility of the clinician to inculcate various methods for its detection into future clinical trials and management strategies for better understanding and outcome of the disease. © 2020 Published by Innovative Publication.

口腔鳞状细胞癌(OSCC)具有显著的全球发病率和同样令人生畏的死亡率。尽管诊断和治疗取得了进步，但口腔癌患者的死亡率和发病率保持不变。OSCC患者最基本的预后指标是颈部淋巴结或远处器官的转移。微转移是指不同于原发病变的恶性细胞的显微沉积。微转移的检测方法有免疫组织化学(IHC)、逆转录聚合酶链反应(RT-PCR)和连续切片等，但在连续切片的淋巴结切片上，可以使用一些可靠的特殊染色剂(如Modified Papanicolaou染色剂和甲苯胺染色剂)检测微转移。不可否认，早期识别OSCC的微转移，特别是在手术后，对患者是有利的，有助于修改治疗方案。微转移是口腔和口咽鳞状细胞癌的一个重要的不良预后因素，临床医生的最大责任是在未来的临床试验和管理策略中灌输各种检测方法，以更好地了解疾病和预后。©2020由创新出版社出版。这是一篇基于CC BY-NC许可的开放获取文章(https://creativecommons.org/licenses/by-nc/4.0/)

Background: Submental flap is an axial pattern, myo-cutaneous flap based on submental artery (branch of facial artery). We have used this novel flap for reconstruction of the intra-oral, as well of the lower and mid face defects created after resection of certain intra-oral malignancies. Materials and Methods: This study included 15 patients and done over a period of 3 years. Cases were operated by a team of surgical oncologists using the same technique and under 2.5 x magnifications (loupe). Any nodes in the region were carefully dissected and sent for frozen section for intra-operative verification of presence or absence of microscopic tumor deposits. Evaluation had been done based on the clinical and pathological staging, nodal status as well as the patient outcome. Results: Out of the 15 patients who underwent reconstruction with submental flap, one patient developed total flap loss, whereas one patient had partial flap necrosis. The remaining 13 patients showed decent clinical outcome and the flap uptake was good. In the follow up period of 2 years, two patients developed regional recurrence (none in the flap donor or recipient sites) and 2 developed distant metastasis. Conclusion: Submental flap is an excellent flap for reconstruction of small to medium size defects for intra-oral as well as lower and mid face. It is useful in medically compromised conditions, old age or low socio-economic status of the patient as these factors preclude the use of a free flap. It is oncologically safe for reconstruction and in the absence of clinical or radiological evidence of nodal disease in sub-mental region and may be considered for reconstruction in N0 as well as N1 patients. © 2020 Published by Innovative Publication.

Chemical carcinogens are supposedly considered to be the key etiological factor of malignancy. The covalent or non-covalent bonds between these chemical and the DNA, RNA, and proteins of human tissue help in the initiation of carcinogenesis wherein, genetic mutation and alteration in the genome transcription supervenes. These carcinogens behave as initiators or promoters of cancer cell growth. Alkylation of DNA, RNA, or proteins and the formation of covalent bonds with them begins initially followed by the promoting effect. Numerous molecular and cellular events causing the transformation of normal cells into neoplastic cells occur in the process. It is assumed though that endogenous molecular pathways could instigate mutations in respective genes with the support of reactive oxygen species thus leading to DNA damage. Thus, this review deals with the basic mechanism and metabolism of chemical carcinogenesis. © 2020 Published by Innovative Publication.

化学致癌物被认为是恶性肿瘤的主要病因。这些化学物质与人体组织的DNA、RNA和蛋白质之间的共价键或非共价键有助于癌变的开始，在癌变过程中，基因突变和基因组转录的改变会发生。这些致癌物是癌细胞生长的启动物或促进物。DNA、RNA或蛋白质的烷基化和与它们形成的共价键首先在促进作用之后开始。许多分子和细胞事件导致正常细胞转化为肿瘤细胞的过程中发生。虽然假设内源性分子途径可以在活性氧的支持下激发各自基因的突变，从而导致DNA损伤。因此，本文就化学致癌的基本机制和代谢作一综述。©2020由创新出版社出版。这是一篇基于CC BY-NC许可的开放获取文章(https://creativecommons.org/licenses/by-nc/4.0/)
