Purpose: Increasing number of older adults are receiving cancer surgeries especially for gastrointestinal cancers, which brings forth attention to age-related postoperative complication prevention. Postoperative delirium (POD) is a common complication that rises after surgical procedures involving general anesthesia, largely in the elderly population. Due to its sudden onset and fluctuating symptoms, POD often goes underdiagnosed and undertreated even though it may lead to various adverse outcomes. POD in GI cancer surgical elderly patients is poorly understood in terms of prevalence, pathophysiology, assessment, treatment and nursing management. We aimed to identify available literature and investigate study results to broaden our understanding of geriatric GI cancer POD. Methods: The search process involved six databases to identify relevant studies abided by inclusion criteria. Results: Eleven studies were selected for this review. Geriatric POD is closely related to frailty and surgical complications. Frailty increases vulnerability to surgical stress and causes cerebral changes that affect stress-regulating neurotransmitter proportions, brain blood flow, vascular density, neuron cell life and intracellular signal transductions. These conditions of frailty result in increased risks of surgical complications such as blood loss, cardiovascular events and inflammation, which all may lead to the POD. Mini Metal State Examination (MMSE), Confusion Assessment Method (CAM) and Delirium Rating Scale-revised-98 (DRS-R-98) are recommended for POD assessment to identify high-risk patients. Conclusion: The POD prevalence ranged from 8.2% to 51.0%. The multifactorial causative mechanism suggests nurses to identify highrisk elderly GI-cancer surgical patients by reviewing patient-specific factors and surgery-specific factors.

Objectives : This study was performed to evaluate the status of psychiatric consultation at a newly opened university hospital, to explore problems related to psychiatric consultation and to contribute for future consultation to be more systematic and more efficient. Methods: The subjects of this study were 284 patients hospitalized at Inha University Hospital between September 1, 1996 and August 31, 1997, who were referred for psychiatric consultation during hospitalization. This study was evaluated demographical characteristics of referred patients, resons for referral, recommendations by psychiatric consultant, clinical diagnoses, psychiatric diagnoses, relationship between referral time and hospitalization following the day of consultation and consultation referral types based upon psychiatrists' reports and patients' medical charts. Results : Most common patients referred to consultation were females aged 20s who visited at the department of internal medicine and related to the risk of suicidal attempts. Mood disorder was the most frequent psychiatric diagnosis, and the most common recommendations were to use psychopharmacological treatment along with outpatient visits. The 30% of subjects were referred to consultation within a day after hospitalization. In the case of consultation referral timing within two days and after three days, there was significant difference between early consultation and shorter hospitalization following the day of consultation. Most frequent type of consultation(29.6%) was categorized as IIIa type(physical complication type as a "Mending" request type). Conclusion : In review of consultation referral timing and consultation referral type of the subjects, who were referred for psychiatric consultation for one year at a newly opened University Hospital, referrals were found to be made within two days after their admission to hospital(50.7%), which was observed to be early request. We found that there was significant association between early consultation and shorter hospitalization following the day of consultation. The physical complication type(29.6%) which belongs to "Mending" request type was found to be the most frequent consultation referral type. This result indicates that more systematic psychiatric consultation is needed for the future.

Purpose: As the care of surgical patients becomes increasingly complex and catheter-based techniques are more frequently applied, the pattern of iatrogenic vascular injuries may be increasing. Major vascular injuries can jeopardize a patient's life or limb survival. The purpose of this study was to examine the current etiology and prognosis for iatrogenic vascular injuries. Methods: We reviewed medical records of 29 cases of iatrogenic vascular injury that were treated Seoul National University Bundang Hospital between October 2003 and October 2008. We studied clinical variables including demographics, cause of injury, clinical presentations, management and prognosis. Results: The mean age was 60.8 years (range: 25-86), and the male to female ratio was 1.9 : 1. The causes of injuries were operation related complication in 18 cases (62.1%), endovascular intervention and diagnostic angiography in 11 cases (37.9%). The types of vascular injury were partial severance in 14 cases, pseudoaneurysm in 8, arteriovenous fistula (AVF) in 3, thrombosis in 2, complete severance in 2. Especially, device related complication including percutaneous closing device were occurred in 9 and the others came from inadvertent physician's procedure. Primary repair were done in 12 cases, end-to-end anastomosis in 5, interposition graft in 4, ligation in 2, patch angioplasty in 1, peudoaneurysm excision and arteriorrhaphy in 1, hematoma evacuation in 1, and endovascular repair in 3. There were 2 cases of mortality, one of them due to hemorrhagic shock and the other due to septic shock. Conclusion: Proper selection of treatment modalities should be important to have better outcome according to the type of injury as well as anatomical location. Each physician should be familiar to new device as well as patient's topographical feature. Immediate referral to vascular specialist is also essential to reduce morbidity.

Objective: The aim of this study was to investigate the efficacy of intraoperative indocyanine green videoangiography (ICG-VA) and intraoperative neuromonitoring (IONM) to prevent postoperative ischemic complications during microsurgical clipping of unruptured anterior choroidal artery (AChA) aneurysms. Methods: We retrospectively reviewed the clinical and radiological records of all patients who had undergone microsurgical clipping for unruptured AChA aneurysms at our institution between April 2001 and December 2019. We compared the postoperative complication rate of the group for which intraoperative ICG-VA and IONM were utilized (group B; n=324) with that of the group for which intraoperative ICG-VA and IONM were not utilized (group A; n=72). Results: There were no statistically significant differences in demographic data between the two groups. Statistically significant differences were observed in the rate of overall complications (p=0.014) and postoperative ischemic complications related to AChA territory (p=0.039). All the cases (n=4) in group B who had postoperative infarctions related to AChA territory showed false-negative results of intraoperative ICG-VA and IONM. Conclusions: Preserving the patency of the AChA is essential to minimize postoperative complications. Intraoperative monitoring tools including ICG-VA and IONM can greatly contribute to lowering complication rates. However, their pitfalls and false-negative results should always be considered.

The purpose of this study is to get related appropriate data for correct awareness and education of the university students who are using contact lens by investigating university students' awareness, present status, using habits and complication of contact lens. The method of survey was made by questionnaires which were spread to the group of 408 university students. The result indicated some characteristics including using daily wear soft lens of 55.7%, the major motive of using them is for cosmetics of 45.6%. Among them, 54.9% experienced complication, and the xerophthalmia was the most conspicuous case in the aspect of the kinds of the complication. In the aspect of the place where they purchased the contact lens, 93% of the users bought them at eye glasses stores. But when they experienced inconveniences of the contact lens, only 18.8% consulted the Stores. In the fact, I think, the users don't seem to trust the stores fully. Furthermore, 43.5% endure the inconveniences when they get them without any treatment. The fact indicates that they don't realize the seriousness of the complication due to contact lens. Reviewing above-stated facts, information and education for correct awareness and managing methods of contact lens, the complication seem 10 be required. In addition, optician specialized knowledge on contact lens and the sense of duty on national eye health improvement seem to be required.

During root canal treatment, overinstrumentation with hand or mechanically driven files can perforate the mandibular canal, allowing the extrusion of endodontic sealers, dressing agents, and irrigant solutions out of the tooth and into the canal. The patient may report symptoms such as pain, hyperesthesia, hypoesthesia, anesthesia, dysesthesia and paresthesia. Such problems must be resolved as quickly as possible to avoid irreversible sequelae caused by certain neurotoxic materials that form part of endodontic sealants. Although there have been no controlled trials of treatment protocols involving endodontically related injuries to the inferior alveolar nerve, the normal therapeutic sequence for this complication is the control of pain and inflammation and, whenever possible, the surgical elimination of the cause. However, total resolution of pain and reduction in or disappearance of paraesthesia after a non-surgical management have been reported. Antiepileptic drugs such as gabapentin or pregabalin have been used for the treatment of neuropathic pain. This article describes a case of inferior alveolar nerve(IAN) damage after endodontic treatment of a mandibular right second molar and the treatment with non-surgical approach using prednisone and gabapentin medication, monitoring the patient's condition with clinical neurosensory examination and current perception threshold test(Neurometer).

Pulmonary sequestration, congenital cystic adenomatoid malformation[CCAM], infantile lobar emphysema[ILE], and bronchogenic cysts are four congenital lesions that show abnormal cystic areas within the lung field in early life. They share similar embryologic and clinical characteristics, Therefore they are sometimes difficult to make differential diagnosis each other, and all require surgical treatment. From 1984 to 1993, 20 patients underwent surgical corrections under these diagnostic categories[10 bronchogenic cyst, 4 pulmonary sequestration, 4 CCAM, and 2 ILE] in the department of thoracic & cardiovascular surgery, Inje University, Pusan Paik Hospital. There were 9 females and 11 males, Ages ranged from 26 days after birth to 69 years. Among them 5 cases of bronchogenic cyst were found out incidentally, but remained all 15 cases were noted as symptomatic cases. Recurrent pulmonary infections, respiratory distress and cough with cystic lesions in chest film were the main characteristics of them. Computed tomography and aortography were available for diagnostic conformation. For all the cases surgical resection were performed: 1 pneumonectomy, 2 bilobectomy, 9 lobectomy, 7 cyst resection and 1 mass[extralobar pulmonary sequestration] resection. All surgical treatments were well tolerated with no physical limitation. There was no operative mortality, and only one postoperative complication[empyema thoracis]. All patients were followed up ranging from 4 months to 9 years. A clinical awareness of these related lesions is important for prompt diagnosis and effective surgical treatment.

Background: Pain medicine often requires medico-legal involvement, even though diagnosis and treatments have improved considerably. Multiple guidelines for pain physicians contain many recommendations regarding interventional treatment. Unfortunately, no definite treatment guidelines exist because there is no complete consensus among individual guidelines. Pain intervention procedures are widely practiced and highly associated with adverse events and complications. However, a comprehensive, systemic review of medical-dispute cases (MDCs) in Korea has not yet been reported. The purpose of this article is to analyze the frequency and type of medical dispute activity undertaken by pain specialists in Korea. Methods: Data on medical disputes cases were collected through the Korea Medical Association mutual aid and through a private medical malpractice liability insurance company. Data regarding the frequency and type of MDCs, along with brief case descriptions, were obtained. Results: Pain in the lumbar region made up a major proportion of MDCs and compensation costs. Infection, nerve injury, and diagnosis related cases were the most major contents of MDCs. Only a small proportion of cases involved patient death or unconsciousness, but compensation costs were the highest. Conclusions: More systemic guidelines and recommendations on interventional pain management are needed, especially those focused on medico-legal cases. Complications arising from pain management procedures and treatments may be avoided by physicians who have the required knowledge and expertise regarding anatomy and pain intervention procedures and know how to recognize procedural aberrations as soon as they occur.

Neuroleptic malignant syndrome (NMS) is a severe iatrogenic complication of treatment with antipsychotic medication. The aim of this review is to provide the clinical characteristics and treatments of children and adolescents with NMS. Searches were conducted in Medline, Korean studies Information Service System (KISS), and Research Information Service System (RISS). Sixteen case reports and two review articles were selected in Medline, and two Korean cases reported in department of emergency medicine and pediatrics were selected from RISS. Heterogeneous and atypical presentations of NMS were observed in children and adolescents. Some noticeable differences were observed between adult patients and child patients with NMS. In addition, symptom presentations related to atypical antipsychotic agents differed from those of typical ones. In treatment, bromocriptine and benzodiazepine were recommended for management of symptoms. In particular, electroconvulsive therapy (ECT) was a useful treatment option. For prevention and early detection of NMS in children and adolescents, evaluation of risk factors and understanding of diagnostic features of NMS are very important.

Spontaneous pneumothorax (SPTx) associated with primary lung cancer is quite rare, but has been reported as the initial presentation or a complication of disease progression. Moreover, chemotherapy-related SPTx in primary lung cancer occurs at a very low frequency, accounting for less than 0.05% of all cases. Here, we report the first case of erlotinib-related SPTx in a patient with advanced lung adenocarcinoma in Korea. After 3 cycles of cisplatin-based chemotherapy as first-line therapy, erlotinib was administered as second-line treatment. Asymptomatic SPTx accompanied by a significant decrease in tumor size was observed in the left lung 7 weeks later. The patient received continuous administration of erlotinib, without additional treatment. This case showed that SPTx can occur in patients with primary lung cancer receiving erlotinib, and asymptomatic chemotherapy-related SPTx in primary lung cancer may not require therapeutic intervention.
