  • The neuroendocrine tumor is a rare thymic neoplasm, which has been regarded as a distinct tumor from thymoma and originates from Kultschizky cell. The pathologic diagnosis of thymic neuroendocrine tumor has been on findings from light microscopy, immunohistochemical studies, and electron microscopy. About 50% of thymic carcinoids are seen with endocrinopathies. Recurrence and extrathoracic metastasis are characteristics of thymic carcinoids. Surgical removal of the initial and recurred tumor is considered to be the most effective treatment. The role of the adjuvant chemotherapy and radiotherapy is still uncertain. Herein we report a case of thymic neuroendocrine tumor, which was resected surgically.

  • The use of dental implants has become a mainstay of rehabilitative and restorative dentistry. With an impressive clinical success rate, there remain a few minor clinical issues with the use of implants such as peri-implant mucositis and peri-implantitis. The use of laser technology with implants has a fascinating breadth of applications, beginning from their precision manufacturing to clinical uses for surgical site preparation, reducing pain and inflammation, and promoting osseointegration and tissue regeneration. This latter aspect is the focus of this review, which outlines various studies of implants and laser therapy in animal models. The use of low level light therapy or photobiomodulation has demonstrated its efficacy in these studies. Besides more research studies to understand its molecular mechanisms, significant efforts are needed to standardize the clinical dosing and delivery protocols for laser therapy to ensure the maximal efficacy and safety of this potent clinical tool for photobiomodulation.

  • Neuroendocrine carcinomas are rare neoplasms of the hypopharynx. Neuroendocrine neoplasms are divided into four main types : carcinoid, atypical carcinoid, small cell carcinoma and paraganglioma. The diagnosis is primarily based on light microscopy and should be confirmed by immunohistochemical investigation. Small cell neuroendocrine carcinoma of the hypopharynx is extremely uncommon tumor and surgical results for this tumor have been disappointing. Chemotherapy and radiotherapy currently appear the most effective forms of therapy. We report our case of small cell neuroendocrine carcinoma of the hypopharynx with the brief review of literatures.

  • Carcinoid tumors arising in the thymus are rare. Since Rosai and Higa in 1972 distinguished these neoplasms from thymomas, fewer than 100 cases have been reported in the world literature. The pathologic diagnosis of thymic carcinoids is been on findings from light microscopy, histochemical studies, and electron microscopy. About 50% of thymic carcinoids are seen with endocrinopathies. Recurrence and extrathoracic metastasis are characteristic of thymic carcinoids. Surgical extirpation of the tumor initially and of the subseguent recurrences in the most effective treatment today The role of adjuvant radiotherapy and chemotherapy is still uncertain. Herein we report a case of thymic carcinoid tumor in a 36-year old male with brief review of literatures.

  • There has been preconceived assumption that, in good architecture, exterior and interior have to be harmoniously related to each other. However, in contemporary architecture, it is easy to witness that this harmonious relationship between exterior and intoner is severely challenged and various exterior surfaces have multi-faceted roles. Rem Koolhaas explained this sort of new situation in the light of 'lobotomy' that is a surgical method for mental disorders, based on the high-rise buildings in the early Manhattan. This study is started with the Rem Koolhaas' lobotomy concept and how this concept is applied to his projects. The multiple roles of exterior surface can be also found in many contemporary architects' projects. Among them, Jacques Herzog & Pierre do Neuron and Toyo Ito's recent projects are discussed to further analyze the new roles of surface and compared with Rem Koolhaas' case. Although the architects discussed present very limited scope of what is happening on the surface of comtemporary architecture, it is hoped to disclose some examples of new relationship between exterior and interior.

  • Thymus gland is a kind of endocrine organ which secretes thymosin and thymoprotein. There can be developed variable lesions like thymoma, thymic hyperplasia, thymic cyst, thymolipoma, and carcinoid tumor of the thymus gland. We have experienced 25 patients of thymic disease: thymoma 12, thymic hyperplasia 11, thymic cyst 1, carcinoid tumor 1. The age distribution were ranged from 3 to 66 years and the sex ratio was 1:1.8 [male to female]. Thymectomy was performed in all cases, but 3 cases with deep infiltration to the adjacent structures were not resectable completely. Malignancy [all thymoma] were 5 and the rest were benign. Two cases were died of recurrence after tumor resection. Myasthenia gravis occurred in 10 cases. Among them, 2 were thymoma and 8 were thymic hyperplasia. We could obtained the result that thymectomized cases reached 2 remission and 5 improvement. Myasthenia gravis treated medically [18 cases] had no remission and only 2 clinical improvement. In the light of these results, early radical thymectomy would be most favorable treatment in not only thymic tumor, but generalized myasthenia gravis.

  • Tissue defect reconstruction using radial forearm free flap (RFFF) is a common surgical technique whose success or failure is mainly dependent on venous drainage. RFFF has two major venous outflow systems, superficial and deep vein. Drainage methods include combining both systems or using one alone. This review aims to recapitulate the vascular anatomy and network of RFFF as well as shed light on deep vein as a reliable venous drainage system. We also discuss basic evidence for and advantages of single microanastomosis with coalesced vein to overcome technical difficulties associated with the deep vein system.

  • The purpose of this study was to observe the trend of compounds release from acrylic resin oral prosthesis when used for drug delivery as well as a restoration. In this study, 10 specimens of heat-cured polymethylmethacrylate material were prepared and loaded with methylene blue biological stain. The specimens were then submerged in vials with 5 ml distilled water for 24 hours. The extraction procedure continued for 4 days, each day the specimens were immersed in another 5 ml distilled water vial. All extracted solutions were analyzed by visible light spectroscopy for absorbance comparison. The statistical results showed that the absorbance values were significantly different in the first day of extraction than the following days. However, there was no statistical difference among the 2nd, 3rd and 4th days of extraction. Biological stain loading to acrylic resin at the mixing stage, and then after extraction in distilled water, showed a burst release during the first day followed by a constant release during the following few days.

  • Phlegmonous esophagitis must be treated aggressively; therefore, appropriate antibiotic therapy and drainage are critical. Although a conventional surgical approach has been used previously, internal drainage could be another treatment option in light of advances in endoscopic techniques. We report 2 cases in which patients suffering from phlegmonous esophagitis were successfully treated with endoscopic intraluminal drainage and antibiotics.

  • Surgical release of elbow contracture is associated with injury to structures traversing the elbow. To date, only one other case report has been published describing anterior interosseous nerve (AIN) palsy that developed immediately after open elbow contracture release and debridement. Here we describe the unique case of a patient that developed AIN palsy 1 week after operation, including magnetic resonance imaging and electrodiagnostic studies, to shed some light on the etiology of this rare complication.
