Achieving an aesthetic implant-supported restoration in the single tooth missing case can be challenging when the implant site is in e anterior region. The objective of this report is to focus on presurgical evaluation of implant site and systematic development of related prosthetic modalities. An accurate diagnostic evaluation, a systematically developed pesurgical plan, and knowledge and clinical skill of the various related therapeutic modalities are indispensible. Collection of patient's information, appropriate abutment selection, soft tissue contour, implant axis, and occlusion need to be discussed for aesthetic clinical outcome. For aesthetic restoration, such as surgical guide stent for precise implant positioning customized provisional restoration for development of optimal periimplant soft tissue contours, and fabrication customized abutment (mesiostructure) for veriable emergence profile, are recommended.

Bilateral renal obstruction is a rare critical condition, requiring a prompt diagnostic approach and treatment to restore the renal function. The most commonly observed obstructive uropathy in children is congenital malformation, such as posterior urethral valves and bilateral ureteropelvic junction obstruction. Malignant pelvic masses obstructing the ureter are widely reported in adults but are rarely observed in children. The treatment of ureteral obstruction related to pelvic malignancy is a therapeutic challenge with a median survival duration of 3-7 months in adults; however, pediatric patients with pelvic malignancy leading to ureteral obstruction had better outcomes, with a reported 5-year mortality rate of 20%, than the adult patients. Here, we report a rare case of bilateral ureteral obstruction associated with pelvic rhabdomyosarcoma presenting with acute kidney injury treated by ureteral diversion with double J stent, and concommittent emergency hemodialysis, leading to restoration of good renal function. We suggest that bilateral ureteral obstruction should be released as soon as possible using surgical or interventional approach to minimize the obstruction period, and subsequential chemotherapy may contribute to improvement of survival and recovery of renal function.

We report a case with dysphagia for solids. A 51-year-old man with benign esophageal stricture was transferred for endoscopic treatment. He had lye ingestion history at 9 years old and underwent esophagectomy with right colonic interposition for the treatment of the benign esophageal stricture. But his symptom was acting up 2 years ago and lasted afterward even though he had underwent endoscopic treatments for dysphagia several times, including balloon dilation and stent insertion. He had polypoid enhancing wall thickening around anastomosis site of stomach with perigastric soft tissue density and suspicious nodular extension to omentum on the small bowel computed tomography. So he had a surgical resection of small bowel and jejunojejunostomy, and the pathological result was adenocarcinoma, intestinal type with soft tissue infiltration. Later he underwent total gastrectomy with segmental resection of interpositional colon and segmental resection of duodenum and ileo-colic anastomosis revision. And recently he has been on chemotherapy.

Malignant hilar biliary obstruction (MHO), an aggressive type of perihilar biliary obstruction caused by cholangiocarcinoma, gallbladder cancer, or other metastatic malignancies, has a poor prognosis. Surgical resection is the only curative treatment for biliary malignancies. However, most patients with MHO cannot undergo surgery upon presentation because of their advanced inoperable state or poor performance resulting from old age or comorbid diseases. Therefore, palliative biliary drainage is required to improve symptomatic jaundice and quality of life. Preoperative biliary drainage is controversial in resectable cases of MHO. Preoperative biliary drainage should be considered according to specific selection criteria. Palliative drainage is currently the mainstay of symptomatic treatment. Compared with percutaneous access, primary endoscopic palliation using plastic or metal stents has recently shown higher technical feasibility and clinical success without increasing the frequency of adverse events, even in high-degree MHO. However, the use of stents still has numerous limitations, including challenges in determining the optimal type of stent, number of stents, deployment method, and additional local therapies. Therefore, this report presents the current optimal endoscopic drainage status for MHO based on recent guidelines and published literature.

Background: The management of hepatolithiasis combined with intrahepatic cholangicarcinoma (IHHCC) remains a challenge due to poor prognosis. The aim of this study was to summarize our diagnosis and cure experience of IHHCC over the recent 10 years. Methods: From January 1996 to January 2006, 66 patients with IHHCC were reviewed retrospectively. Results: Of the 66 patients, 52 underwent surgical resection (radical resection in 38 and palliative in 14) and 8 patients abdominal exploration, while the other 6 cases received endoscopic retrograde biliary internal drainage and stent implantation. In this series, correct diagnosis of advanced stage was made during operation in 8 cases (8/60, 13.3%) and all of them (underwent unnecessary abdominal exploration, among them the positive rate of CA19-9 was 100%, and the positive rate of CEA was 87.6% (7/8), incidence rate of ascites was 100% and short-term significant weight loss was 100%, with median overall survival of only 4 months. Conclusion: Radical resection is mandatory for IHHCC patient to achieve long-term survival, the CT and MR imaging features of IHHCC being concentric enhancement. Patients with IHHCC have significant higher CA199 and significant higher CEA and short-term significant weight loss and ascites should be considered with advanced stage of IHHCC and unnecessary non-therapeutic laparotomies should be avoided.

The common errors in preoperative treatment plan for the orthognathic surgery can be occurred during cast impression, cast mounting procedure with face-bow transfer, surgical stent fabrication, and so on. One of the most common errors exists during mounting process of the model on the articulator. Accurate mounting of dental casts to articulator should be achieved by transferring the 3-dimensional spatial relationship of the maxillary arch to an articulator. A face-bow is used for transfer this relationship to articulator, usually by relating the face-bow to a plane of reference of maxillary cast. The purpose of this study is evaluation of the accuracy of face-bow transferring of maxillary model to the articulator. The maxillary casts of thirty patients for orthognathic surgery were mounted on articulator with an face-bow instrument. The relationship of occlusal plane angle to Frankfort horizontal plane relations were compared the cephalogram with the cast-mounted articulator. As a result of this study, the significant difference between the maxillary occlusal planes angle in the cephalogram and articulator were found. The results were followed, 1. The mean occlusal plane angle in cast-mounted articulator was $13.5^{\circ}\;(SD{\pm}5.4)$. 2. The mean occlusal plane angle in cephalogram was $10.4^{\circ}\;(SD{\pm}4.3)$. 3. The mean difference of occlusal plane angle between cast-mounted articulator and cephalogram was $3.3^{\circ}\;(SD{\pm}4.6)$. According to the result, we should suggest that the occlusal plane angle to Frankfort plane in cast-mounted articulator is more steeper than that of cephalogram. And then, maxillofacial surgeon should try to get a more predictable result by suggesting the proper correction method and mounting the cast accurately.

Hematoma is quite a common complication of femoral arterial catheterization. However, to the best of our knowledge, there have been no previous studies regarding deep vein thrombosis (DVT) caused by compression of a vein due to a hematoma. We report a case of a hematoma developing after femoral arterial catheterization and causing extensive symptomatic DVT. A 59-year-old male was seen in our Emergency Department with right lower leg swelling 15 days after coronary stent implantation performed using right femoral artery access. Computed tomographic (CT) scanning revealed a large hematoma (45 mm in its longest diameter) compressing the common femoral vein and with DVT from the right external iliac vein to the popliteal vein. Due to the extensive DVT involvement, we decided to release the compressed common femoral vein by surgical evacuation of the large hematoma. However, even following evacuation of the hematoma, as the DVT did not resolve soon, further mechanical thrombectomy and catheter-directed thrombolysis were performed. Angiography then showed nearly resolved DVT, and the leg swelling was improved. The patient was discharged with the anticoagulation medication, warfarin.
