Birt-Hogg-Dube syndrome (BHD) is a rare autosomal dominant disorder characterized by the formation of hair follicle tumors, kidney tumors, and pulmonary cysts with recurrent spontaneous pneumothorax. A 44-year-old woman visited Wonkwang University Hospital with mild dyspnea. A chest X-ray on admission revealed pneumothorax in both lung fields. Chest computed tomography (CT) revealed both pneumothorax and multiple, irregularly shaped, variable-sized cysts in both lung fields. Upon physical examination, white dome-shaped papules were observed on the face. Histological examination of the skin lesion confirmed fi-brofolliculoma, and genetic studies revealed a folliculin gene mutation. Abdominal CT revealed a 1-cm small solid renal mass at the lower pole of the right kidney. We surgically removed the renal tumor, and a histological diagnosis of oncocytoma was made. Here, we report a case of BHD that demonstrated all three clinical manifestations; this is the first case report of its kind in Korea. (Korean J Med 2019;94:379-382)

BSSRO (bilateral sagittal split ramus osteotomy) is an effective surgical method for maxillofacial deformities. Rigid fixation using a plate and screws can stabilize bony segments and induce early mouth opening. Though this procedure has a low complication rate, normal function and esthetic recovery is achieved through proper and early management of the complications. Complications consisting of temporomandibular disorders, sensory disturbances due to inferior alveolar nerve damage, open bite, malunion or nonunion, and facial nerve palsy occur, but these rarely develop. Facial nerve palsy causes the muscles involved in facial expression to depress, which results in ocular dryness or retinal damage. When facial nerve palsy develops, early management involving steroid medication and physical therapy is effective. In the case of severe damage, surgical intervention should be considered. A 20-year-male patient came to the oral and maxillofacial surgery department for orthognathic surgery. The mandible was set back by BSSRO under general anesthesia. Facial nerve palsy was observed on the left side of the face: steroid and vitamins were administered early and physical therapy was performed daily. These forms of management can aid in function and allow for gradual esthetic recovery. Presumed causes were excessive soft tissue retraction or soft tissue injury by the osteotome at the horizontal osteotomy of the ramus. Careful dissection, retraction and a precise osteotomy are needed for protection of the facial nerve. If nerve damage is observed, early management can help in the recovery of facial nerve function and esthetics.

Purpose: This study evaluated the prognosis and survival rate of SLA (Sandblasted, Large-grit and Acid-etched) implants and it also evaluated the prosthodontic complications and the associated factors. Methods: Twenty seven patients (14 men and 13 women, mean age: 54.9) who visited Chosun University Hospital Implant Center with the chief desire for placement of an implant in an edentulous area from March, 2008 to December 2008 and who received placement of a SLA implant ($Implantium^{(R)}$, Dentium Co., Korea) were selected for this study. Results: The average follow-up period was 15 months and the study was based on the treatment records, radiographs and clinical examinations. A total of 69 implant cases were retrospectively assessed for the width and length of the implant, the primary and secondary stability, the combined surgery, the employed bone graft material and barrier membrane, the status of the opposing tooth, implant failure and the prosthetic complications. During the follow-up period (average: 15 months), the accumulative survival rate of the 69 implants in 27 patients was 100%. Complications such as infection, sinusitis and fixture exposure after surgery were seen for 5 implants in 4 patients. Complications such as screw loosening, contact loosening and peri-implant gingivitis after prosthodontic treatment occurred in 7 cases (10.14%). Conclusion: This study reports placement of SLA implants may cause various complications, yet the final accumulative survival rate was 100%. The SLA implant ($Implantium^{(R)}$) has an excellent clinical survival rate and outcome.

Purpose: The purpose of this study was to examine the appropriate degree of set-back of the mandible by evaluating the rate of relapse after surgery. Methods: Among the patients who visited our hospital from January 2002 to January 2007 and who underwent orthognathic surgery, of the patients available for follow-up observation, the rate of relapse after surgery was investigated according to the set-back degree. The patients were divided into groups by the degree of set-back, and relapse was evaluated by the radiographs performed the day after surgery, 6 months after surgery, 1 year after surgery, 2 years after surgery and 3 years after surgery. Results: In cases that exceeded the limit of posterior movement of the mandible (13 mm) or that had the wrong position of the condyle, a greater tendency toward relapse was shown. Conclusion: Based on the results of this study, among the cases that required a large amount of posterior movement of the mandible, two jaw surgeries accompanied by bilateral sagittal split ramus osteotomy (BSSRO) and LeFort I osteotomy are recommended.

Purpose: Orthognathic surgery is required in patients with severe skeletal disharmony and facial asymmetry, which results in functional and esthetic improvement. Recently, bimaxillary surgery has become generalized. Establishment of the occlusal plane among several other factors included in the surgery plan is a major consideration for the diagnosis and treatment plan and it is also an important factor for postoperative stability. Methods: In this study, we assessed postoperative stability of occlusal plane, B-point, and pogonion point on 20 patients who underwent two-jaw surgery in the Chosun Dental Hospital from 2000 to 2007. Preoperative and postoperative states and at least a one year postoperative follow-up were compared. Results: The postsurgical relapse volume of the occlusal plane to the SN plane and the FH plane was $-0.26{\pm}2.8^{\circ}$ and $-0.44{\pm}3.29^{\circ}$, respectively and after two-jaw surgery, the stability of occlusal plane was maintained. The horizontal relapse degree was $0.85{\pm}0.46$ mm and $0.76{\pm}0.48$ mm, respectively, and the vertical relapse degree was $1.16{\pm}0.36$ mm and $1.13{\pm}0.71$ mm of the B point and the Pogonion point at the time after minimal 1 year. Conclusion: The vertical relapse amount was shown to be slightly larger than the horizontal relapse amount.

Sinus floor elevation is a predictable and standard procedure for the treatment of the posterior maxilla before insertion of dental implants. Although overall complication rates are low, complications can occur including sinus membrane perforation, infection of sinus, swelling and hemorrhage. The most common complication is membrane perforation. Recently, various techniques and materials for repair of perforation to the sinus membrane have been proposed. The purpose of this article is to report on various techniques and materials that can be used for repair of perforations to the sinus membrane. The search protocol used was the following electronic database: Pubmed, with a time limit from 1998 to 2009. The key words such as 'sinus lift', 'sinus augmentation', 'sinus floor elevation', 'sinus graft', 'sinus perforation', 'repair of sinus perforation' and 'repair of sinus membrane' were used, alone and in combination, when searching the database. Various techniques have been proposed to manage of perforation of sinus membranes. These include that the use of collagen membranes, demineralized freeze-dried human lamellar bone sheets, processed human allografts, lamella bone, buccal fat pads and suturing. Implant success rate ranges from 69.9% to 98.9%.

졸-겔 방법에 의하여 제조된 TiO2와 TiO2-SiO2 광촉매를 이용한 음용수 중의 대장균 살균과 엔도톡신 제거에 관한 연구를 수행하였다. 대장균 살균실험은 대장균이 포함된 물이 순환되는 annular-흐름식 광촉매 코팅 반응기에서 수행되었다. 대장균의 살균능은 TiO2와 TiO2-SiO2 광촉매의 아나타제 결정성피크의 세기와 비례하였다. UV-A 조사하에 TiO2가 코팅된 반응기에서 2시간 내에 대장균을 100% 살균시킬 수 있었으며, 대장균 사멸시 생성되는 독성물질인 엔도톡신이 존재하지 않았다. 그러나 UV-C 조사하에서는 30분 이내에 대장균을 100% 살균할 수 있었으나 엔도톡신이 완전히 제게되지 않았다. 따라서 광촉매와 UV-A 조사가 음용수 살균에 유용함을 알 수 있었다.

Background/Aims: Endoscopic submucosal dissection (ESD) has been widely performed. However, procedure related-complications and the risk of tumor recurrence are limitations. We analyzed the clinicopathological characteristics of patients who underwent curative additional gastrectomy (gastrectomy) after ESD. Methods: The clinical characteristics of cases underwent gastrectomy after ESD were retrospectively analyzed. Results: Between January 2002 and August 2010, 1,512 cases underwent ESD for early gastric cancer (n=511) or adenoma (n=1,001). Thirty-two cases (2.1%) underwent gastrectomy after ESD. Thirty cases (2.0%) were EGC and 2 cases (0.1%) were adenoma. Extended indication, larger tumor size and piecemeal resection were risk factors for gastrectomy after ESD. According to the causes of gastrectomy, 13 cases underwent gastrectomy due to complications (40.6%; bleeding in 9, perforation in 4), and 19 cases based on pathological results (incomplete resection in 13, lymphatic invasion in 6). In cases with incomplete resection, the rate of residual tumor and lymph node metastasis after gastrectomy was 69.2% (75% lateral margin, 60% deep and 75% both) and 7.7%, respectively. Three (50%) of the 6 cases with lymphatic invasion had lymph node metatstasis. Conclusions: The causes of gastrectomy after ESD were the procedure-related complications, the incomplete resection and lymphatic invasion. For complete and curative ESD, endoscopists should try to minimize complications and determine the depth of invasion accurately before ESD. (Korean J Gastroenterol 2012;59:289-295)
