Pain from cancer is a major problem of managing the oral cancer patients in terminal stage. Overall, pain is reported by about 50% of patients at all stages of cancer and by over 70% with advanced neoplasms. Unrelieved pain can be incapaciting and preclude a satisfying quality of life. But, pain is often poorly assessed, and many clinicians lack sufficient knowledge to optimize cancer pain treatment. There are three basic approaches to the control of pain : modifying the source of pain, altering the central perception of pain, and blocking the transmission of pain to the central nervous system. The optimal use of these approaches and an individualized plan for pain control can maximize both quality and duration of life in dying patients. Opioid analgesics are are the mainstay of pharmacologic treatment. Practical opioid therapy include selection of both drug and route, dose titration, and management of side effects. We present our experienced pharmacologic treatment protocol for cancer pain management that collaborated by Dept. of Hospice, Catholic Medical Center. It will acts as a guideline for our colleague to facilitate the translation of current knowlegde into the clinical practice.

3.Three-Year Experience of Pouch Dilatation and Slippage Management after Laparoscopic Adjustable Gastric Banding.
Yonsei Medical Journal 2014;55(1):149-156
PURPOSE: Pouch dilatation and band slippage are the most common long-term complications after laparoscopic adjustable gastric banding (LAGB). The aim of the study is to present our experience of diagnosis and management of these complications. MATERIALS AND METHODS: The pars flaccida technique with anterior fixation of the fundus was routinely used. All band adjustments were performed under fluoroscopy. We analyzed the incidence, clinico-radiologic features, management, and revisional surgeries for treatment of these complications. We further presented the outcome of gastric plication techniques as a measure for prevention of these complications. RESULTS: From March 2009 to March 2012, we performed LAGB on 126 morbidly obese patients. Among them, 14 patients (11.1%) were diagnosed as having these complications. Four patients (3.2%) had concentric pouch dilatations, which were corrected by band adjustment. Ten (7.9%) had eccentric pouch with band slippage. Among the ten patients, there were three cases of posterior slippage, which were corrected by reoperation, and seven cases of eccentric pouch dilatation with anterior slippage. Three were early anterior slippage, which was managed conservatively. Two were acute anterior slippage, one of whom underwent a revision. There were two cases of chronic anterior slippage, one of whom underwent a revision. The 27 patients who underwent gastric plication did not present with eccentric pouch with band slippage during the follow-up period. CONCLUSION: The incidence of pouch dilatation with/without band slippage was 11.1%. Management should be individualized according to clinico-radiologic patterns. Gastric plication below the band might prevent these complications.

Annals of Surgical Treatment and Research 2020;98(2):82-88
PURPOSE:
The objective of this study was to survey potential candidates for bariatric/metabolic surgery for procedure preferences.
METHODS:
Questions asked were divided into 5 categories: (1) demographic and anthropometric data, comorbidities, and favored surgery; (2) awareness of safety, effectiveness, and complications of each type of surgery; (3) discordances in opinion between self-selected and medically recommended procedures; and (4, 5) reasons for/against particular surgery.
RESULTS:
From 1 October to 15 November 2018, 104 respondents adequately responded and were included in the analysis. The number (%) of female respondents was 79 (76.0%). The number (%) of respondents by decade was 17 (16.3%) in their 20s, 65 (62.5%) in their 30s, 19 (18.3%) in their 40s, and 3 (2.9%) in their 60s, respectively. Mean body mass index was 37.1 ± 6.3 kg/m2. Comorbidities were type 2 diabetes in 34 (32.7%) and hypertension in 35 (33.7%). The most favored procedure was sleeve gastrectomy (SG) in 78 (75.0%), adjustable gastric band (AGB) surgery in 12 (11.5%), Roux-en-Y gastric bypass (RYGB) in 6 (5.8%), and gastric plication (GP) in 8 (7.7%). Major reasons for choosing procedures were; “adjustable†for AGB, “stomach sparing†for GP, “excellent weight loss†for SG, and “comorbidity resolution†in RYGB.
CONCLUSION
Candidates for bariatric/metabolic surgery favored SG followed by AGB, GP, and RYGB, and their choices were compatible with current evidence-based clinical practice.

Microsurgical clipping is considered the treatment of choice for ruptured intracranial aneurysms. However, ruptured posterior circulation aneurysms remain technically difficult to expose or clip and outcomes in these cases are poorer than those seen in cases of anterior circulation aneurysms. Therefore, endovascular treatment becomes another treatment option in cases of ruptured posterior circulation aneurysms. But, the vertebral artery may not be selected due to luminal narrowing, which are atherosclerotic stenosis clinically, congenital anomalies, or acquired kinking, and structural problem of angle between aorta, subclavian artery and vertebral artery. In these cases, other approaches can be used through, for example, subclavian, axillary, or brachial artery approach. But sometimes such prcedures may be also inappropriate. One other approach is direct percutaneous vertebral artery approach. Though this one also doesn't overcome many clinical and anatomical problems. The authors present two cases of ruptured basilar tip aneurysms which was treated with endovascular Guglielmi detachable coil embolization with open surgery and catheterization, because the one had anatomical problem, and the other had structural problem.

PURPOSE: The usual technique of temporomandibular joint (TMJ) reduction, recommended by most emergency medicine textbooks, consists of downward forces applied to the mandible. However, it has been the authors' experience that conscious sedation and significant force is required to achieve reduction. For that reason, we designed a new method of TMJ reduction. The purpose of our study is to introduce the new method of TMJ reduction and to compare the traditional method with the new method. METHODS: We performed a prospective, randomized trial with 52 patients who were diagnosed as having a TMJ dislocation. The patients were divided into two groups: the group treated with the traditional method (25 cases) and treated with the new method (27cases). Patients with histories of trauma or inflammatory signs were excluded from this study. The new method is an extraoral approach in which the operator applies the coronoid process on the face in the posteroinferior direction. RESULTS: Age, sex, and history of TMJ dislocation showed no statistical differences between the two groups. Reduction of the TMJ dislocation was achieved in 15 (60.0%) of the traditional method group and in 25 (92.6%) of the new method group (p=0.005). The means of the reduction time were 11.8+/-6.2 sec in the traditional method group and 6.6 +/- 3.3 sec in the new method group (p=0.007). CONCLUSION: The new method was an effective treatment for TMJ dislocation without any sedations. I had a higher success rate and a shorter reduction time than traditional method.

We performed a primary vitrectimy using scleral depression technique for uncomplicated rhegmetogenous retinal detachment and intended to highlight the importance of scleral depression technique. The indications for the primary vitrectomy were eyes with multiple or posteriorly located retinal breaks, unidentified retinal breaks, vitreous opacities, strong vitreous tractions on the retina tear flap, and aphakic/pseudophakic retinal detachments, Removal of vitreoretinal traction and vitreous base dissection using scleral depression technuque were performed in sixty-eight eyes of rhegmatogenous retinal detachment uncomplicated with proliferative vitreoretinopathy of grade C or worse. Scleral segmental buckle or encircling was also placed in 60 of 68 eyes. The retina was reattached after the primary operation in fifty-seven eyes(80.9%), and after reoperations in remaining eleven eyes(19.1%). Postoperative visual acuity was 0.4 or better in thirty-eight eyes (55.9%), and worse than 0.025 in eight eyes(11.8%). Vitrectomy in conjuction with scleral depression technique would be effective in increasing surgical success rate in selected cases of retinal detachment surgery.

The pencil beam convolution (PBC) algorithms in radiation treatment planning system have been widely used to calculate the radiation dose. A new photon dose calculation algorithm, referred to as the anisotropic analytical algorithm (AAA), was released for use by the Varian medical system. The aim of this paper was to investigate the difference in dose calculation between the AAA and PBC algorithm using the intensity modulated radiation therapy (IMRT) plan for lung cancer cases that were inhomogeneous in the low density. We quantitatively analyzed the differences in dose using the eclipse planning system (Varian Medical System, Palo Alto, CA) and I'mRT matirxx (IBA, Schwarzenbruck, Germany) equipment to compare the gamma evaluation. 11 patients with lung cancer at various sites were used in this study. We also used the TLD-100 (LiF) to measure the differences in dose between the calculated dose and measured dose in the Alderson Rando phantom. The maximum, mean, minimum dose for the normal tissue did not change significantly. But the volume of the PTV covered by the 95% isodose curve was decreased by 6% in the lung due to the difference in the algorithms. The difference dose between the calculated dose by the PBC algorithms and AAA algorithms and the measured dose with TLD-100 (LiF) in the Alderson Rando phantom was -4.6% and -2.7% respectively. Based on the results of this study, the treatment plan calculated using the AAA algorithms is more accurate in lung sites with a low density when compared to the treatment plan calculated using the PBC algorithms.

Although inverted papillomas of urinary tract have been reported, the lesion of the ureter is rare and peculiar tumor characterized by unique microscopic finding. The prognosis of ureteral inverted papilloma is very favorable, only small number progress to higher grade tumor. We report 2 cases of ureteral inverted papilloma which were treated by segmental resection with end-to-end anastomosis of ureter.

Bisphosphonates decrease osteoclastic activity and reduce bone resorption, therefore they are used in the treatment of patients with hypercalcemia secondary to malignancy or metastatic bone cancer, Paget's disease and osteoporosis. Recently, cases of jaw bone necrosis have been reported to be associated with the use of bisphosphonates. In patients with rheumatoid arthritis, osteoporosis is frequently developed because of osteoclast activation and steroids which are used for treatment and bisphosphonates are frequently prescribed. A 76-year-old female patient with rheumatoid arthritis was treated with alendronate for the management of osteoporosis for 36 months, and she was presented with pain and swelling on left mandibular area and gingival pus discharge. The patient was treated with curettage of necrotic bone, and biopsy showed avascular necrosis of mandible.
