Gastric cancer is the most common malignancy and the incidence is steadily increasing in Korea. The principal treatment modality for gastric cancer is surgical extirpation of tumor along with draining lymph nodes. Gastrectomy with D2 lymph node dissection has been well established as a standard of surgery and improved the survival of gastric cancer patients. Recently, technological advances are drastically reshaping the landscape of surgical treatment of gastric cancer. One of the most notable trends is that minimal access surgery becomes dominating the treatment of early stage diseases. For advanced diseases, the standard access surgery is considered a reference treatment. Although there is a pilot study underway to evaluate the feasibility of the application of minimal access surgery to advanced gastric cancer (AGC), the evidence for oncological safety is not yet provided sufficiently. Based on the recent randomized controlled trials, the extent of surgery for AGC has re-defined as para-aortic lymph node dissection dose not add any survival benefit while increasing surgery-related morbidities. In addition, it is now accepted as a standard operation omitting unnecessary procedures such as splenectomy and/or distal pancreatectomy for prophylactic lymph node dissection. Conceptual and technical innovation has contributed to decreasing morbidity and mortality without impairing oncological safety. All these recent advances in the field of gastric cancer surgery would be concluded in maximizing therapeutic index for gastric cancer while improving quality of life.
The purpose of this study is to investigate the occupational diseases(the number of medical treatment) of fire officials by using time-series analysis. The results of the study are as follows. First, the average rates of the occupational diseases of fire officials were as follows: ① internal diseases were the highest at 9.24% in December, the lowest at 7.76% in February, ② otolaryngologic diseases were the highest at 9.29% in December, the lowest at 6.74% in August, ③ dermatological diseases were the highest at 10.03% in July, the lowest at 7.35% in January and February, ④ surgical diseases were the highest at 10.38% in November, the lowest at 5.62% in February, ⑤ orthopedic diseases were the highest at 9.69% in March, the lowest at 7.52% in November, ⑥ neurosurgical diseases were the highest at 9.33% in April, the lowest at 6.82% in February, ⑦ neurological diseases were the highest at 9.47% in December, the lowest at 7.06% in October, and ⑧ mental health diseases were the highest at 9.93% in December, the lowest at 6.51% in May. Second, the seasonal decomposition of the disease occurrence of fire officials were described by assigning seasonal factor(S), trend factor(T), circulation factor(C) and irregular factor(R): ① internal diseases were 1.075(S) × 189.355(T·C) × 1.174(R) = 238.975(F), ② otolaryngologic diseases were 1.023(S) × 69.605(T·C) × 1.040(R) = 74.000(F), ③ dermatological diseases were 1.002(S) × 73.088(T·C) × 0.874(R) = 64.000(F), ④ surgical diseases were 1.099(S) × 27.229(T·C) × 0.669(R) = 20.000(F), ⑤ orthopedic diseases were 1.115(S) × 73.182(T·C) × 1.213(R) = 99.000(F), ⑥ neurosurgical diseases were 0.993(S) × 27.836(T·C) × 1.303(R) = 36.000(F), ⑦ neurological diseases were 1.029(S) × 62.417(T·C) × 1.152(R) = 74.000(F), and ⑧ mental health diseases were 1.210(S) × 8.781(T·C) × 1.035(R) = 11.000(F).
Purpose: The aim of this retrospective study was to investigate the cumulative success rate, the implant survival rate, and the occurrence of biological complications in implants supporting full-arch immediately loaded rehabilitations supported by upright and tilted implants. Methods: The clinical records and periapical radiographs of patients who attended follow-up visits were collected, and information was recorded regarding marginal bone loss resorption, the occurrence of peri-implant infectious diseases, and the implant survival rate. Implants were classified as successful or not successful according to two distinct classifications for implant success. Results: A total of 53 maxillary and mandibular restorations including 212 implants were analysed, of which 56 implants were studied over the full five-year follow-up period. After five years, the cumulative success rate was 76.04% according to the Misch classification and 56.34% according to the Albrektsson classification. The cumulative implant survival rate was 100%, although one implant was found to be affected by peri-implantitis at the second follow-up visit. Conclusions: The cumulative success rate of the implants dropped over time, corresponding to the progression of marginal bone resorption. The prevalence of peri-implantitis was very low, and the implant survival rate was not found to be related to the cumulative success rate.
Background: To evaluate the prevalence and features of other gynecologic or surgical lesions in endometrial cancer (EMC) patients. Materials and Methods: Clinico-pathological data of EMC patients who were treated in the institution from 1995 to 2012 were collected. Data collected were age, stage of disease according to the FIGO 2009 criteria (FIGO), histopathology, tumor grade, adjuvant therapy, other gynecologic or surgical lesions, follow-up period, and living status. Results: The mean age of 396 patients was $56.7{\pm}10.64years$. Abnormal uterine bleeding was the most common presenting symptom (90.1%). Bleeding was accompanied with pelvic mass in 7.7% and 5.4% had only a pelvic mass. Abnormal cervical cytology was found in 3.8%. Approximately 75% had early stage diseases and 86% had endometrioid histology. We found 55.8% of EMC patients had other gynecologic lesions: 89.6% benign and 9.5% malignant. Some 4.5% had pre-invasive cervical/vulva/vagina lesions. The two most common gynecologic lesions were myoma uteri and ovarian tumors. Focusing on the latter, approximately 14% were benign while 8% were malignant. Among 364 patients with available data, surgical lesions were found in 11.8%, 5.7% benign and 9.2% malignant. The most common benign surgical condition was chronic appendicitis while breast and colon cancers were the two most common malignant lesions found. Conclusions: More than half of EMC patients had other gynecologic lesions including benign and malignant tumors. Surgical lesions were also found in more than one-tenth of patients. Careful pre-operative evaluation and intra-operative inspection are advised for proper management and better prognosis.
Acute abdomen is a condition with sudden abdominal pain that may require immediate surgical treatment. The causes of acute abdomen in pediatric patients are diverse, and can be categorized in broad range from diseases requiring surgery to diseases requiring medication or clinical observation only. The role of the imaging study in children with acute abdomen is to distinguish between patients who need medication and patients who need surgery by identifying diseases that cause abdominal pain, if possible. Since intussusception and appendicitis are the leading causes of acute abdomen requiring surgical treatment in children, it is important to exclude intussusception in young infants complaining of acute abdominal pain and exclude acute appendicitis in older children with acute abdomen. In this paper, we introduce intussusception, acute appendicitis, midgut volvulus, Meckel's diverticulum and duplication cyst, which has characteristic imaging finding of the disease that can cause acute abdomen in pediatric patients.
Background: Recent advance in video technology, endoscopic equipments, and surgical techniques have expanded the use of thoracoscopy from diagnosis of the pleural diseases to treatment of the various intrathoracic diseases. Video Assisted Thoracoscopic Surgery(VATS) is a pretty new and fascinating thoracic surgical modality, and so we present our early VATS resuls. Methods: Using Video Thoracoscopic techniques in 30 patients for 10 months from July 1992 to April 1993, we had performed a variety of procedures. These incuded (1) bleb resections in 18 patients (19 cases), (2) mediastinal tumor excision in 4, (3) lung biopsies for parenchymal pulmonary disease in 3, (4) pleural biopasies in 3, (5) pleural tumor excision in 1, (6) and pleuropericardial window in 1. Results: There were no mortality associated with the procedures. We had minor 8 complications; prolonged air leak in 3 patients, prolonged serous drainage in 2, recurrence of pneumothorax in 1, Honer's syndrome in 1, and hoarseness in 1 patient. None of the 30 patients had reverted to the conventional full thoracotomies. Mean postoperative hospital stay of non-complicated pneumothoraces was about 5 days, which was a little shorter than conventional thoracotomy group. Conclusion: Though we had somewhat higher postoperative complication rate due to lack of experiences in the begining, we were able to convince that VATS had benifical value for patients; lesser postoperative pain, shorter hospitalization, quicker recovery time, and cosmetically superior scar. The role of VATS can be expanded to the diagnosis and treatment of various thoracic diseases, even to the cardiovascular diseases, with satisfactory outcome and less postoperative morbidity.
This report is concerned to our experience of 10 cases of open heart surgery under the extracorporeal circulation at the Department of Thoracic and Cardiovascular Surgery, Capital Armed Forces General Hospital during the period between May, 1982 and February, 1983. 1. Six cases were male and two cases were female. Age was varied from 21 years to 50 years and mean age was 34 years. 2. The cases included 2 Ventricular Septal Defects, 1 Atrial Septal Defect, I Tetralogy of Fallot and 6 acquired valvular heart diseases. 3. The surgical managements were 3 primary repairs for Ventricular Septal Defects and Atrial Septal Defect, I total correction for Tetralogy of Fallot and 6 mitral valve replacements with bovine xenograft by Ionescu-Shiley combining 3 Tricuspid annuloplasties [ De Vega method ] and 1 deauricularization of left atrial appendage for acquired valvular heart diseases. 4. The average cardiopulmonary bypass time was 37 minutes for acyanotic congenital heart diseases and 92 minutes for cyanotic heart disease and acquired valvular heart diseases. And the average aortic cross clamping time was 19 minutes for the former and 70 minutes for the latter. 5. Postoperatively, there were 1 hemolytic anemia, 1 congestive heart failure, 1 hemolytic jaundice and 1 thermal burn as complications, but there was no operative mortality. 6. All patients received valve replacement were recommended anticoagulation with Persantin and Aspirin.
Recent advances in the surgical treatment of congenital disorders of the heart have necessitated an accurate preoperative diagnosis. Right heart catheterization has become widely accepted as a research tool and diagnostic test to detect the heart diseases, especially in the congenital heart anomalies. Right heart catheterizations were carried out in 50 cases of congenital heart diseases at Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital, during the period of June, 1975 through September 1978. In age distribution, 27cases were below 10 years of age, 18 cases between 11 and 20, and 5 cases above 20 male to female ratio was 2.8:1. The distribution of congenital heart diseases was VSD [42%], TOF [36%], PDA [10%], ASD [8%], and PS[4%]. Of these, 44 cases [88%], were compatible with the clinical impressions that were made preliminarily before cardiac catheterization, and all the cases except 1 case of VSD was correlated well with the postoperative diagnosis. The right heart catheterization is considered to be reliable and accurate toll in the preoperative diagnosis of congenital heart diseases. These procedures caused complications such as left side hemiplegia [lcase], occlusion of the femoral artery [lcase], and transient ventricular tachycardia [1case], and so the complication rate of right heart catheterization was 6% [3 cases]. None of patients who have undergone right heart catheterization was died.

Purpose: There are numerous reports about the usefulness of antibiotics such as doxycycline or metronidazole in the conventional treatment for the patients with chronic periodontal diseases. However, seldom are the reports about effects of vitamins or nutraceuticals. The purpose of this study was to evaluate the effects of nutrient supplement including multiple vitamins and neutraceuticals with PRF-K2 from plants and seaweed in treatment of the patients with chronic periodontitis which is needed a nonsurgical or a surgical treatment by evaluating the clinical parameters and the gingival crevicular fluid volume. Methods: The systemically healthy and nonsmoking patients diagnosed with chronic periodontitis were divided into a nonsurgical group and a surgical group. They were also divided into the test group with nutrient supplements and the control group without nutrient supplements. In the nonsurgical group, the clinical parameters (probing depth, clinical attachment level, sulcus bleeding index, and plaque index) and the gingival crevicular fluid volume were checked on baseline, at 1 week, at 3 week and at 9 week after a supplement treatment. In the surgical group, the clinical parameters and the gingival crevicular fluid volume were also checked at 15 week after a surgical treatment. Results: In both nonsurgical and surgical groups, reduction of pocket depth and increment of clinical attachment level were revealed in the test group compared with the control group, but there was not statistically significant difference (p>0.05), and sulcus bleeding index was decreased with statistically significant difference (p<0.05). In addition, plaque index was decreased with statistically significant difference (p<0.05) in the nonsurgical group. Gingival crevicular fluid volume was decreased with statistically significant difference (p<0.05) at week 9 in both non-surgical and surgical groups. Conclusions: In conclusion, our results demonstrate that providing nutrient supplement in both nonsurgical or surgical periodontal treatments may improve gingival inflammation and gingival crevicular fluid.
