Thirteen consecutive patients with carcinoma of the tongue underwent surgical resection and reconstruction with the ALTF. There was only one complete flap failure, the resultant flap success rate is 92%. Preliminary assessment of recovering tongue function was acceptable and donor site complications were minimal. Therefore, we believe that the ALTF is a reliable flap for hemiglossectomy defect reconstruction. Patients and Methods From March 2018 to December 2018 at the 5th Surgical Department of Ho Chi Minh City Oncology Hospital, 13 consecutive patients with squamous cell carcinoma of the tongue requiring hemiglossectomy underwent resection and reconstruction with ALTF. The histologic type of all tumors were squamous cell carcinoma. The research method is a case series report. The function of postoperative tongue is evaluated by three doctors Tables 1,2.

Introduction Tongue cancer is the most common cancer of the oral cavity. Surgery is the main treatment modality for this neoplasm. With small and superficial defects, resection surgeries do not affect the function of the tongue. However, if the large lesions invade deeply, the procedures will leave large defects that require reconstruction to restore the functions of the tongue, the most important of which are speech and deglutition. Tongue reconstruction objectives include not only the recovery of tongue volume, but also the movement of the tongue. Currently, free flap is the ideal choice for tongue reconstruction. The Radial Forearm Flap (RFF) and Anterolateral Thigh Flap (ALTF) are the two most widely used flaps. RFF was introduced in 1981 and has gained popularity for reconstruction the oral cavity. This flap shows several advantages, but it also has disadvantages concerning the scar of donor site [1]. The ALTF is now widely used for reconstruction in Asia; this flap has some significant advantages for reconstruction of head and neck. It can be raised as a subcutaneous flap, a fasciocutaneous flap or a myocutaneous flap and can resurface large defects in head and neck. In addition, it is pliable and suitable for three dimensional defects of the tongue and the floor of the mouth. Another advantage is that it has a large and long vascular pedicle; donor site can be closed primarily and functional loss of donor site is minimal.

{"title":"Significance of Using SYPRO Ruby against CBB R-250 for Visualizing Haematoxylin Stained Proteins in Gels.","authors":"Noor Feuza Hussain,&nbsp;Sulma Ibrahim Mohammed","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Laser Capture Micro-dissection (LCM) is a technique that is used to isolate specific tumor cells from a heterogeneous tumor tissue sample.To aid in identifying and dissecting pure tumor cells from other parts of the tissues such as the stroma, tissues are stained with Haematoxylin and Eosin. The cells are then used for protein, RNA or DNA extraction. However, the effect of Haematoxylin and Eosin or other different stains routinely used in the laboratories on the recovery, quantity and quality of proteins especially for down stream application such as 2-dimenssional gel electrophoresis (2-DE) and MS not known. This study, determined the effect of Haematoxylin staining on the detection methods used in 1-D SDS-PAGE for protein quantification. A series of concentration of proteins were obtained from human pancreatic whole tissue and was run on a SDS-PAGE parallel with the proteins obtained from Haematoxylin stained and unstained tissues.The protein band intensities were measured with a densitometer after separately stained with SYPRO Ruby or CBB R-250.The protein band intensity ratios of the whole tissue and Haematoxylin stain/ Haematoxylin unstained tissue were calculated. According to the ratios,there was an intensity loss in the Haematoxylin stained proteins when detecting through CBB R -250 but not from SYPRO Ruby. This was due to the structure and reactivity of these two stains towards proteins in the presence of Haematoxylin. The study recommends the use of SYPRO Ruby instead of CBB R-250 to visualize proteins in 2-DE gels when tissues were stained with Haematoxylin.</p>","PeriodicalId":73876,"journal":{"name":"Journal of oncology research and therapy","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6498853/pdf/nihms-1002087.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37216511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
