PURPOSE: Type I endoleak is known to be associated with sac enlargement and occasional rupture, therefore, the treatment of type I endoleak is recommended at the time of diagnosis. The aim of this study was to identify the significance of early type I endoleak found on completion angiography. METHODS: Between January 2000 and December 2012, a total of 86 patients underwent endovascular abdominal aortic aneurysm repair (EVAR) and 10 patients (11.6%) were diagnosed with type Ia endoleak on completion angiography. Clinical and radiologic data were reviewed retrospectively. RESULTS: Of the 10 patients, two underwent EVAR with custom-made stent-grafts in the initial stage and both of them needed immediate treatment: one case involved open repair while the other involved insertion of an additional stent-graft. In 8 patients, the amount of leakage decreased after repeated balloon molding. They were managed conservatively and followed up with computed tomography angiography within 2 weeks after EVAR. In 7 of the 8 cases, type Ia endoleaks disappeared. In one patient with a persistent endoleak and a folded posterior wall of the stent-graft, coil embolization was performed 1 week after EVAR. With a median follow-up of 12 months (range, 1-61 months), no patients showed recurrence of type I endoleak or sac expansion. CONCLUSION: Type I endoleaks diagnosed on completion angiography sealed spontaneously in 7 of 10 patients (70.0%). In cases of decreased amounts of leakage after balloon molding, simple observation may be an alternative to repetitive procedures. The long-term follow-up of patients with self-sealed type I endoleaks is mandatory.

BACKGROUND: The aim of this study was to investigate the current state of the assistive devices and appliances provision system for cerebral palsy patients registered with brain disability. METHODS: From 2003 to 2013, we analyzed the records of cerebral palsy patients who had assistive devices and appliances provisioned at least once in their lives based on National Health Information Database. Patients with cerebral palsy were divided into three groups: infants and toddlers, school age and adolescence, and adults. RESULTS: Data on short leg plastic orthoses, ankle joint orthoses, and wheelchair were mainly analyzed. The types of ankle joint orthoses divided into three categories: limited, 90° limited, and Klenzac. Limited ankle joint orthoses was most frequently supported of the three in all age groups. Powered wheelchair and scooter were most supported to adult patients. When the re-supply duration was evaluated, the duration was suitable to the duration on guideline of regulation of re-supplement according to the related laws in adult patients but not in infants/toddlers and school age/adolescence as the actual re-supplement duration was much shorter than the reference value. CONCLUSION: This study confirmed the pattern of assistive devices and appliances supply differed depending on the age of cerebral palsy patients.

Isolated torsion of the fallopian tube is an uncommon event. It is a difficult condition to evaluate clinically before exploration. But once happened, promt surgical intervention may allow for preservation of the tube. Recently we experienced isolated tubal torsion with diagnosed hydrosalpinx, and report it with a brief review of literatures.

OBJECTIVES: Vulnerability marker in biological relatives of schizophrenia may be very useful in identifying the propensity for the development of schizophrenia. This study suggests that the relatives at risk for genetically developing schizophrenia have impairments in several domains of cognition, social function and affective function as a vulnerability marker. METHODS: A neurocognitve function test, a social function test and an affective function test were administered to fifteen healthy relatives from families with two or more patients with schizophrenia (geneticallly high risk subjects). Fifteen healthy controls matched for age and gender were recruited in this study. RESULTS: Compared to the control subject, the genetic high risk subjects performed significantly more poorly in the selective attention and recall memory of neurocognitive function. The high risk subjects also had lower scores in independence-performance and independence-competence of the social function test and emotion control of the affective function test. CONCLUSION: Selective attention, recall memory, independence-performance, independence-competence and emotion control ability may be a valuable marker for genetic study of schizophrenia.

Esophageal carcinosarcoma is a rare malignant esophageal neoplasm consisting of both carcinomatous and sarcomatous elements, with an incidence of 0.5%. There have been only a few case reports of carcinosarcoma and squamous cell carcinoma coexisting in the esophagus. However, all of these are cases of synchronous or metachronous development of carcinosarcoma after chemoradiotherapy in patients of esophageal squamous cell carcinoma. A 53-year-old man underwent esophagogastroduodenoscopy because of chest pain for several months. Endoscopic examination revealed a huge pedunculated esophageal polypoid mass. Endoscopic submucosal dissection (ESD) was performed and histopathologic examination confirmed spindle cell carcinoma (carcinosarcoma). He refused additional esophagectomy. After 21 months, third follow-up endoscopy showed poorly-demarcated flat, faint discolored lesions at different location from the previous ESD site and endoscopic biopsies confirmed squamous cell carcinoma. To the best of our knowledge, this is the first case of metachronous development of esophageal squamous cell carcinoma in a patient with esophageal carcinosarcoma.

OBJECTIVES: The aims of this study were to identify the intake and following process for subjects at high risk of transition to schizophrenia and to examine the neurocognitive, social, and emotional functions of the subjects compared with healthy controls. METHODS: Symptomatic individuals judged at high risk for schizophrenia ('clinical high risk') within Youth Clinic were assessed and followed up. They performed a neurocognitive function test, a social function test and an affective function test. Twenty healthy controls were recruited in this study. RESULTS: Among eighty-two subjects contacted through the Youth clinic, sixteen subjects were judged as the clinical high risk group. Fourteen subjects among the clinical high risk group showed deficits in several domains of neurocognitive functions, such as visual recall memory, verbal short term memory and executive function. Social and affective functions are also impaired in the clinical high risk group compared with healthy controls. Two of 15 subjects (13%) developed a psychotic disorder within 6 months. CONCLUSION: This study illustrates the state of follow-up study for a clinical high risk group. Despite low numbers and short durations, some impairment of several functions in the clinical high risk group suggests possible predictors of psychosis.

It is very rare for the primary lung cancer to metastasize to gastrointestinal tract, which has poor prognosis. A 72-year-old man admitted with dyspnea and a mass lesion in the left lower lobe on chest roentgenogram and chest computed tomogram(CT). Large cell carcinoma of the lung was diagnosed by percutaneous needle biopsy. Also gastroduodenoscopy was conducted for evaluation of gastrointestinal symptoms, such as indigestion and epigastric discomfort. Large cell carcinoma of duodenum was diagnosed by biopsy of duodenal polyp, which was considered to be metastasized from the primary lung cancer. Palliative radiation therapy was performed, but he died 2 months after diagnosis. We report a rare case of large cell carcinoma of the lung with metastasis to uodenum.

BACKGROUND: Common cold is the most frequently seen ambulatory disease in primary care clinic of Korea. This study investigated the perspectives and expected pattern of health care utilization of patients who visit a primary care clinic in order to understand patients' health care behavior for treating common cold and to consider how to educate them effectively. METHODS: We surveyed 570 patients and their accompanying people who visited family medicine clinic and the health promotion center of a university hospital by questionnaire, in which we asked the patients what they think of the cause, symptom, and treatment of common cold and their pattern of health care utilization. RESULTS: The respondents replied that the cause of common cold was a virus (446, 85.3%), a bacteria (58, 11.3%) or others (18, 3.4%). Among the total, 475 respondents (88.6%) replied that they had taken cold medicine before and 264 respondents (55.7%) reported that the symptoms took 1-2 weeks to recover. A total of 285 respondents (58.3%) replied that they prefer red to go to the doctor and 198 (40.5%) replied that they prefer to go to a pharmacy. The respondents who thought that symptoms of common cold takes longer than one week tended to choose to visit a doctor. Patients thought that antibiotics (54.4%) and those that relieved common cold symptoms earlier (30.1%) were 'strong' cold medicine. CONCLUSION: The results of this survey showed that the difference in patients' perspectives made an effect on the patients' treatment seeking behavior. Even though medicine did not take effect to relieve symptoms, most patients wanted to continue to visit physicians. The family physician should not give only the prescription, but also make an effort to provide pertinent information to patients and educate them to acquire appropriate perspectives.

OBJECTIVES: Vacuum-assisted breast biopsy (VABB) is a widely used technique for the diagnosis of breast lesions. It is carried out with local anesthesia, but procedural pain and stress are still problematic. Dexmedetomidine is a α-2 receptor agonist that can sedate without significant respiratory depression. The study aimed to report the effectiveness of sedation with monitored anesthesia care (MAC) using dexmedetomidine in VABB. METHODS: This was a retrospective chart review of patients who received VABB under MAC with dexmedetomidine. Forty-seven patients during the period of February 2015 to July 2016 were included. We collected data on patient characteristics, infusion drug and dose, induction to incision time, anesthetic, operation, and recovery time and other complications and vital signs. RESULTS: The mean operating time was 50.1 ± 24.9 minutes, and the anesthetic time was 71.2 ± 28.3 minutes. The mean time from induction to incision was 17.0 ± 5.2 minutes, and the recovery time was 20.1 ± 10.3 minutes. None of the patients needed an advanced airway management. Further, none of them showed hemodynamic instability. CONCLUSIONS: VABB was successfully performed with MAC using dexmedetomidine, and there was no respiratory depression or hemodynamic instability.
