Publication Open Access Eagle’s syndrome and associated pain in head and neck region: A case report and review literature.(2014-05) Rachatawan Leelarangsun; รชตวรรณ ลีลารังสรรค์; Surakit Visutiwatanakorn; สุรกิจ วิสุทธิวัฒนากร; Surakit Visutiwatanakorn; สุรกิจ วิสุทธิวัฒนากร; Mahidol University.

Department of Oral and Maxillofacial SurgeryOrofacial pain is an unpleasant symptom that can originate from several etiologies, including inflammation of the eustachian tube, parotid gland infection, impacted teeth, trauma, carcinoma of pharynx, and trigeminal neuralgia. The most common diagnoses of orofacial pain are cluster headache, migraine, and temporomandibular joint disorders (TMD). On the other hand, elongation of styloid process, also known as Eagle’s syndrome, is often neglected because of its rare occurrence. Orofacial pain related to an elongated process can be relieved by its surgical removal. Therefore, it is important to gather all necessary information by history taking and clinical and radiographic investigation to make the correct diagnosis so that unnecessary treatment and surgeries can be avoided.Publication Open Access Three phase bone scintigraphy in evaluating revascularization and bone formation of natural biomaterial bone graft by using Tc99m MDP in rabbits(2015) Somkiat Huaijantug; Paranee Yatmark; Somsak Wattananit; Phingphol Charoonrut; Thonnapong Thongpraparn; Rujaporn Chanachai; Mahidol University.

Section of Nuclear MedicineThree phase bone scintigraphy (TPBS) examined the viability of bone graft, revascularization, and bone formation using single photon emission computed tomography (SPECT) and the intravenous injection of 99M Technetium methylenediphosphonate (99MTc-MDP). Seven New Zealand White rabbits, aged 8 months had osteotomy of ulna performed, the left ulna substituted for natural biomaterial bone graft, containing gelatin sponge and hyaluronic acid, and the right ulna was replaced by vascularized autogenous bone graft. A post-operative scanning of bone using TPBS was done at 7 days and weekly, at week 1, 2, 4, 6, 8, 12 to evaluate revascularization and bone formation of natural biomaterial bone graft comparing with autogenous bone graft. The results demonstrated that the perfusion index and RCP of natural biomaterial bone graft and the autogenous bone graft in phases 1, 2, and 3 had no statistically significant difference when compared in between each week. The study also showed that, the ratio of the mean counts/pixel of the natural biomaterial bone graft in phase 3 had slightly lower than autogenous bone graft. This study provided model through which TPBS could evaluate revascularization and bone formation in this model. Natural biomaterial bone graft may be the same and as good a revascularization as autogenous bone graft although the bone formation of autogenous bone graft still has more efficiency than natural biomaterial bone.Publication Open Access ความแม่นของการวัดเชิงเส้นเมื่อเปรียบเทียบระหว่างภาพรังสีปริทัศน์และภาพรังสีส่วนตัดอาศัยคอมพิวเตอร์แบบรังสีรูปกรวย(2012-01) ศิรินันท์ วิเศษสินธุ์; Sirinun Wisetsin; ทวีพงศ์ อารยะพิศิษฐ; Tawepong Arayapisit; ขวัญชนก แสวงศรี; Khwanchanok Sawaengsri; พิชญพล ชุณหชัชวาลกุล; Pitchayapol Chunhachatchavalkul; พิชญา ไวโรจนกุล; Pichaya Wairojanakul; สาธิดา ชาติบัญชาชัย; Sathida Chatbunchachai; สุภัค งามสม; Supak Ngamsom; ศิรินันท์ วิเศษสินธุ์; Sirinun Wisetsin; มหาวิทยาลัยมหิดล. คณะทันตแพทยศาสตร์. ภาควิชารังสีวิทยาช่องปากและแม็กซิลโลเฟเชียล; มหาวิทยาลัยมหิดล. คณะทันตแพทยศาสตร์. ภาควิชากายวิภาคศาสตร์on the panoramic and the cone beam computed tomographic radiographs as well as directly on the mandibles. The relative error of both imaging modalities was assessed. The measurement obtained from each radiograph was compared with that obtained from the same... mandible by paired t-test (α=.05). The difference of the relative error between radiographic techniques was analyzed using t-test (α=.05). Results: Linear measurement on each radiographic technique had no significant difference from the actual lengthPublication Open Access Using cone-beam computerized tomography before intiating intentional endodontic treatment.(2011-05) Raweewan Arayasantiparb; ระวีวรรณ อารยะสันติภาพ; Chitvaree Leetrakulwanna; ชิตวรี ลีตระกูลวรรณา; Danuchit Banomyong; ดนุชิษณ์ พนมยงค์; Danuchit Banomyong; ดนุชิษณ์ พนมยงค์; Mahidol University.

CBCT was used to obtain three-dimensional details of tooth. Results: From the CBCT images, the highest points of pulpal horns were clearly demonstrated. The minimal remaining tooth thicknesses obtained from CBCT were 3.25, 3.5 and 4.0 mmPublication Open Access Development of a prototype lateral flow immunoassay (LFI) for the rapid diagnosis of melioidosis.(2014-03-20) Houghton, Raymond L.; Reed, Dana E.; Hubbard, Mark A.; Dillon, Michael J.; Chen, Hongjing; Currie, Bart J.; Mayo, Mark; Sarovich, Derek S.; Theobald, Vanessa; Direk Limmathurotsakul; ดิเรก ลิ้มมธุรสกุล; Gumphol Wongsuvan; Narisara Chantratita; นริศรา จันทราทิตย์; Peacock, Sharon J.; Hoffmaster, Alex R; Duval, Brea; Brett, Paul J.; Burtnick, Mary N.; AuCoin, David P.; AuCoin, David P.; Mahidol University.

The B. pseudomallei capsular polysaccharide (CPS) and numerous protein antigens were identified as potential candidates. Here, we describe... the development of a diagnostic immunoassay based on the detection of CPS. Following production of a CPS-specific monoclonal antibody (mAb), an antigen-capture immunoassay was developed to determine the concentration of CPS within a panel of melioidosis patientPublication Open Access Clinical performance and wear characteristics of veneered lithia-disilicate-based ceramiccrowns.(2008-05) Kallaya Suputtamongkola; Anusavice, Kenneth J.; Chatcharee Suchatlamponga; Phira Sithiamnuaia; Chantana Tulapornchai; กัลยา ศุพุทธมงคล; ชัชรี สุชาติล้ำพงศ์; พีระ สิทธิอำนวย; ฉันทนา ตุลาพรชัย; Kallaya Suputtamongkol; กัลยา ศุพุทธมงคลObjectives. The objectives of this study were to characterize the clinical performance and wear characteristics of lithia-disilicate-based ceramic crowns. Methods. Thirty posterior crowns were made using the heat-pressing techniquePublication Open Access Retinal changes in visceral leishmaniasis by retinal photography(2014) Maude, Richard James; Ahmed, BUM Wahid; Abu Hayat Md Waliur Rahman; Rahman, Ridwanur; Majumder, Mohammed Ishaque; Menezes, Darryl Braganza; Sayeed, Abdullah Abu; Hughes, Laura; MacGillivray, Thomas J; Borooah, Shyamanga; Dhillon, Baljean; Dondorp, Arjen M; Faiz, Mohammad Abul; Mahidol University. Faculty of Tropical Medicine. Mahidol-Oxford Tropical Medicine Research UnitBackground: In visceral leishmaniasis (VL), retinal changes have previously been noted but not described in detail and their clinical and pathological significance are unknown. A prospective observational study was undertaken in Mymensingh, Bangladesh aiming to describe in detail visible changes in the retina in unselected patients with VL. Methods: Patients underwent assessment of visual function, indirect and direct ophthalmoscopy and portable retinal photography. The photographs were assessed by masked observers including assessment for vessel tortuosity using a semi-automated system. Results: 30 patients with VL were enrolled, of whom 6 (20%) had abnormalities. These included 5 with focal retinal whitening, 2 with cotton wool spots, 2 with haemorrhages, as well as increased vessel tortuosity. Visual function was preserved. Conclusions: These changes suggest a previously unrecognized retinal vasculopathy. An inflammatory aetiology is plausible such as a subclinical retinal vasculitis, possibly with altered local microvascular autoregulation, and warrants further investigation.
