The pharmacotherapy of depression has reduced morbidity and improved outcome for many depressive patients. A wide range of classical and new antidepressants are available for their treatment. However, 30-40% of all patients do not respond sufficiently to the initial treatment and present adverse effects. Pharmacogenetics studies the genetic basis of an individual's ability to respond to pharmacotherapy. Recently, some reports on serotonin transporter gene polymorphisms and their influence on the response to antidepressive therapy provide an interesting diagnostic tool in assessing the chances of response to antidepressants. We also investigated the relationship between serotonin transprter polymorphisms(5-HTTLPR) and the long-term effect of the antidepressant treatment. 128 depressive patients were enrolled into 2nd year study. The therapeutic response of each subset was not different at 8th, 16th week, but the subset with homozygote(l/l) of long variant showed a better therapeutic response to antidepressant than the heterozygote(l/s) of long and short variant, which showed a better therapeutic response than the subset with homozygote (s/s) of short variant at 1st year and 2nd year after the antidepressant treatment. This result shows that the serotonin transporter polymorphisms may be related to the long-term effect of antidepressant treatment. The potential for pharmacogenomics, the use of genetic information to guide pharmacotherapy and improve outcome by providing individualized treatment decisions, has gained increasing attention. pharmacogenomics will contribute to individualize drug choice by using genotype to predict positive clinical outcomes, adverse reactions, and levels of drug metabolism. Personalized medicine, the use of marker-assisted diagnosis and targeted therapies derived from an individual molecular profile, will impact the antidepressant therapy and this approach will replace the traditional trial-and-error practice of medicine.

Objective : Eleven patients treated with posterior cerebral artery[PCA] aneurysm during 6.3-years period are retrospectively reviewed to determine treatment outcome. Methods : Eleven patients with PCA aneurysm were treated from January 1998 to May 2004. Their medical records and radiologic studies were reviewed retrospectively. The records of these patients were analysed with particular reference to their demographic details, mode of presentation, and treatment outcome. Results : Of the 11 patients, 8 patients presented with symptoms related aneurysmal bleeding. Three patients had unruptured PCA aneurysms. Open or endovascular surgery was performed in 9 patients; None of these patients exhibited a third nerve palsy, visual field deficit, or hemiparesis at the time of presentation. Postoperatively, 2 made a good recovery, 2 had a moderate disability because of cerebral infarction after surgery, and 5 had a severe disability because of cerebral infarction after surgery. Of 2 conservatively treated patients, 1 was doing well but the other died as a result of brain swelling. Conclusion : The treatment of the PCA aneurysms is difficult regardless of the aneurysmal size, site, and treatment modality. All reasonable treatment to reduce the risk of associated morbidity should be considered.

Objective : Very large (20-25 mm) and giant (${\geq}25mm$) intracranial aneurysms have an extremely poor natural course, and treatment of these aneurysms remains a challenge for endovascular and surgical strategies. This study was undertaken to describe our experiences of endosaccular treatment of very large and giant intracranial aneurysms with parent artery preservation. Methods : From January 2005 to October 2016, twenty-four very large or giant aneurysms in 24 patients were treated by endosaccular coil embolization with parent artery preservation. Nine (37.5%) aneurysms were ruptured and 15 were unruptured, and of these 15, 11 were symptomatic cases and 4 were incidentally discovered. The cohort comprised 17 women and 7 men of mean age 58.5 years (range, 26-82). Mean aneurysm size was 26.0 mm (range, 20-39) and 13 of the 24 aneurysms were giant. Results : Immediate angiographic results were complete occlusion in nine (37.5%) cases, remnant neck in six (25.0%), and remnant sac in nine (37.5%). Overall procedural related morbidity and mortality rates were 12.5% and 4.2%, respectively. Angiographic follow-up was available in 16 patients (66.7%). Mean and median follow-up periods were 27.2 (range, 2-77) and 10.5 months, respectively. In 12 cases (12/16, 75%) stable occlusion was achieved, four cases (4/16, 25%) had recanalized, and two of these were retreated with additional coiling. At clinical follow-up of the nine ruptured cases, three patients (33.3%) achieved a good clinical outcome (Glasgow outcome scale [GOS] score of 4 or 5), two (22.2%) a poor outcome (GOS score of 2 or 3), and four patients (44.4%) expired (GOS 1). On the other hand, of the 15 unruptured cases, 13 patients (86.7%) achieved a good clinical outcome (GOS 4 or 5), one patient a poor outcome (GOS score of 2 or 3), and one patient expired (GOS 1). Conclusion : The present study shows endosaccular treatment of very large or giant intracranial aneurysms with parent artery preservation is both feasible and effective with acceptable morbidity and mortality.

최근에 Roller loop electrode를 이용한 경요도전립선전기기화술에 관심이 집중되고 있다. 저자들은 전립선비대증에서 전립선전기기화술의 가치를 알아보기 위해 Roller loop electrode를 이용한 전립선전기기화술(TEVP, 17례)을 레이저전립선절제술(VLAP, 39례)과 전통적 경요도전립선절제술(TURP, 59례)과 비교 분석해 보았다. TEVP는 효과 면에서는 전통적인 경요도전립선절제술에는 미치진 못하지만 VLAP과는 유사한 효과를 보였으며 안전성면과 경제적인 면에서는 VLAP을 능가하는 치료법으로 사료된다. 본 연구가 적은 환자를 대상으로 10개월까지 관찰한 결과이고 경요도전립선전기기화술의 초기 경험이라 명확한 결론을 내리기에는 다소 성급한 면이 있으나 전통적인 전립선절제술에 비해 짧은 입원기간, 짧은 요도관유치 기간 및 적은 출혈 등을 보여주며 레이저 시술의 단점인 고가장비가 필요 없다는 점에서는 전통적 전립선절제술의 대체 술기로 높이 평가되어진다.

A study on the morbidity of syphilis among 729 workers in Po Hang and Ul San Industiral Complexes at the routine periodical examination was performed. In addition to the morbidity, factors related to the disease infection such as educational level, religion, preventive measures taken by the workers, history of urethritis, and so on were studied and analysed to check significant relation. The results were as follows: 1. VDRL and RPR tests were undertaken to determine the sensitivity and specificity of RPR test which was utilized for all the workers studied. It revealed 86.4% of sensitivity and 87.7% of specificity from RPR test, and 81.8% of sensitivity and 90.1% of specificity from the VDRL test compared with RPCF test. There were 87.4% of agreement rate between RPR and VDRL. Actually, RPR was more sensitive but less specific than VDRL, and found to be a satisfactory screening test for syphilis especially in the fields. 2. Among the workers in Po Hang Area 24.0% of them revealed reactive result, and in Ul San Area 5.2% revealed reactive result showing 4.6 times of risk among workers in Po Hang Area. 3. There were no statistically significant differences between RPR reactive rates and personal characteristics such as educational level, religion, history of urethritis experience, history of coitus with prostitute, and preventive measures of V.D. taken by workers if evaluated by area of Po Hang and Ul Srn separately. 4. V.D. could be encountered as an occupational disease in certain conditions of working places and the psychosocial problems of workers. And so, it is necessary that all the workers working in special estates such as in Po Hang Industrial Complex should be checked to be screened out by RPR test at periodical examinations and part of pre-employment examination also should include RPR test to be compared with. Regardless of the workmen's compensation, establishment of V.D. treatment clinic or system for such industrial workers is urgently needed. Health education regarding V.D. is another subject to be performed.

Objective : Paraclinoid segment internal carotid artery (ICA) aneurysms have historically been a technical challenge for neurovascular surgeons. The development of microsurgical approach, advances in surgical techniques, and endovascular procedures have improved the outcome for paraclinoid aneurysms. However, many authors have reported high complication rates from microsurgical treatments. Therefore, the present study reviews the microsurgical complications of the extradural anterior clinoidectomy for treating paraclinoid aneurysms and investigates the prevention and management of observed complications. Methods : Between January 2004 and April 2008, 22 patients with 24 paraclinoid aneurysms underwent microsurgical direct clipping by a cerebrovascular team at a regional neurosurgical center. Microsurgery was performed via an ipsilateral pterional approach with extradural anterior clinoidectomy. We retrospectively reviewed patients' medical charts, office records, radiographic studies, and operative records. Results : In our series, the clinical outcomes after an ipsilateral pterional approach with extradural anterior clinoidectomy for paraclinoid aneurysms were excellent or good (Glasgows Outcome Scale : GOS 5 or 4) in 87.5% of cases. The microsurgical complications related directly to the extradural anterior clinoidectomy included transient cranial nerve palsy (6), cerebrospinal fluid leak (1), worsened change in vision (1), unplanned ICA occlusion (1), and epidural hematoma (1). Only one of the complications resulted in permanent morbidity (4.2%), and none resulted in death. Conclusion : Although surgical complications are still reported to occur more frequently for the treatment of paraclinoid aneurysms, the permanent morbidity and mortality resulting from a extradural anterior clinoidectomy in our series were lower than previously reported. Precise anatomical knowledge combined with several microsurgical tactics can help to achieve good outcomes with minimal complications.

Objective : Although middle cerebral artery (MCA) aneurysms are less amenable to coil embolization, an increasing number of studies support favorable endovascular treatment for them. The purpose of this study is to compare the outcomes of two different treatments (surgery versus coiling) and evaluate the benefits of surgical clipping for MCA aneurysms. Methods : Here we retrospectively analyzed the outcomes of 178 ruptured and unruptured MCA aneurysms treated in patients between September 2008 and April 2012. Parameters assessing treatment outcomes include degree of aneurysm occlusion, presence of regrowth, clinical status, and complications. Results : Among 178 MCA aneurysms, 153 were treated surgically. After a mean follow-up of 12 months, the surgery group showed a clinically significant complete occlusion rate (98%) compared with the coiling group (56%) (p<0.001). Follow-up radiologic evaluation showed a higher regrowth rate (four of 16 cases) in the coiling group than in the surgery group (one of 49 cases) (p=0.003). There was no statistically significant difference in favorable clinical outcome rate between the two groups. The procedure-related permanent morbidity and mortality rates were 2% (three of 153 cases) in the surgery group and 0% (0 of 25 cases) in the coiling group. Conclusion : Compared to endovascular treatment, surgical neck clipping for both ruptured and unruptured MCA aneurysms results in a significantly higher complete obliteration rate and less regrowth. Therefore, even in this endovascular era, we still recommend surgical clipping as the primary treatment option for MCA aneurysms rather than coil embolization.

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.

Background and Objective: Even though major salivary gland tumor is a rare disease, the diversity of histopathologic characteristics makes treatment decisions difficult. The aim of this study is to analysis the clinical experience of our major salivary gland tumor and to suggest a guideline of treatment. Materials and Method: Sixty-eight major salivary gland tumors and tumor-like glandular enlargements treated at Sanggye Paik Hospital during the past seven years between June, 1995 and January, 2002 are analyzed for histopathologic diagnosis, treatment modality, clinical manifestation, local control, and treatment-related morbidity, recurrence rate, retrospectively. Results: In twenty-eight patients the swellings were diagnosed as non-tumorous condition. The clinical features, diagnostic and surgical management of fourty salivary neoplasms involving the parotid and submandibular glands are correlated with their histological features. Conclusion: We have concluded that salivary gland neoplasms are needed multimodal treatment, because of their highly variable biologic behavior in each tumor type. Thirty-four cases were benign and six cases were malignant. Most of benign cases were pleomorphic adenoma and they showed wide age-distribution. In six malignant cases, there were acinic cell carcinoma, adenocarcinoma, carcinoma ex-plemorphic adenoma, myoepithelioma, and adenoid cystic carcinoma.

Purpose: Meconium-related ileus is common in preterm infants. Without proper management, it can cause necrotizing enterocolitis and perforation requiring emergent operation. This study was conducted to describe the efficacy and safety of ultrasound-guided Gastrografin enema at bedside for preterm infants with meconium-related ileus. Methods: Between March 2013 and December 2014, this study enrolled preterm infants with birth weight <1,500 g, who were diagnosed with meconium-related ileus requiring ultrasound-guided Gastrografin enema refractory to glycerin or warm saline enemas. Gastrografin was infused until it passed the ileocecal valve with ultrasound guidance at bedside. Results: A total of 13 preterm infants were enrolled. Gestational age and birth weight were 28.6 weeks (range, 23.9-34.3 weeks) and 893 g (range, 610-1,440 g), respectively. Gastrografin enema was performed around postnatal day 8 (range, day 3-11). The success rate was 84.6% (11 of 13 cases). Three of these 11 infants received a second procedure, which was successful. Among 2 unsuccessful cases, one failed to pass meconium while the other required surgery due to perforation. The time required to pass meconium was $2.8{\pm}1.5hours$ (range, 1-6 hours). The time until radiographic improvement was $2.8{\pm}3.4days$ (range, 1-14 days) after the procedure. Conclusion: Ultrasound-guided Gastrografin enema at bedside as a first-line treatment to relieve meconium-related ileus was effective and safe for very low birth weight infants. We could avoid unnecessary emergent operation in preterm infants who have high postoperative morbidity and mortality. This could also avoid transporting small preterm infants to fluoroscopy suite.
