OBJECTIVE: To evaluate the safety and efficacy of the laparoscopic incidental appendectomy during gynecologic laparoscopic operation. Methods: This study was evaluated for the clinical analysis of 118 patients who underwent laparoscopic assisted vaginal hysterectomy(LAVH group, 65 cases) and LAVH with laparoscopic incidental appendectomy(LAVH + IA group, 53 cases) at the Wallace Memorial Baptist Hospital from Oct. 1996 to Nov. 1998. RESULTS: The following results were obtained: 1) There was no significant difference between two groups in regard to age. The mean age was 45.7 years in LAVH group and 43.8 years in LAVH + IA group. 2) There was no significant difference between two groups in mean operative time. The mean operative time was 90.4 minutes in LAVH group and 97.5 minutes in LAVH + IA group. 3) The mean appendectomy time was 7.1 minutes. 4) The mean time recovering normal bowel activity was 46.2 hours in LAVH group and 45.8 hours in LAVH + IA group. There was no significant difference between two groups. 5) The mean hospital stay was 6.4 days in LAVH group and 5.7 days in LAVH + IA group. There was no significant difference between two groups. 6) The postoperative complications occurred in 11 cases(9.3 %). The serious complications of appendectomy was not found. 7) Of the 53 appendices removed, 5(9.4 %) were abnormal pathologic findings. CONCLUSION: Laparoscopic incidental appendectomy during laparoscopic operation was not found to influence the operation time, hospital stay, gas passing time, but there is one case of wound infection due to incidental appendectomy. Therefore, a large number of study should be performed to evaluate the safety and efficacy of laparoscopic incidental appendectomy during laparoscopic operation.

Contrary to ventricular mural thrombi, left atrial appendage thrombi are extremely rare in cerebral infarction correlated with acute myocardial infarction but they can be easily detected by transesophageal echocardiography(TEE). We expierienced a case of cerebral infarction which was suspected to be caused from the thrombi in left atrial appendage in a patient with acute myocardial infarction. The cerebral infarction was developed 2 days after myocardial infarction had been occurred and any source of the thrombi could not be detected except in left atrial appendage. The diagnosis was established by TEE and also aided by transthoracic echocardiography, brain computed tomography.

PURPOSE: To evaluate changes in total cerebral blood flow (tCBF) with aging, parenchymal volume changes and vascular abnormalities, using 2 dimensional (D) phase-contrast magnetic resonance imaging (PC MRI). MATERIALS AND METHODS: Routine brain MRI including T2 weighted image, time-of-flight (TOF) MR Angiography (MRA) and 2D PC MRI were performed in 73 individuals, including 12 volunteers. Normal subjects (12 volunteers, and 21 individuals with normal MRI and normal MRA) were classified into groups according to age (18 -29, 30 -49 and 50 -66 years). For the group with abnormalities in brain MRIs, cerebral parenchymal volume changes were scored according to the T2 weighted images, and atherosclerotic changes were scored according to the MRA findings. Abnormal groups were classified into 4 groups: (i) mild reduction in volume, (ii) marked reduction in volume by parenchymal volume and atherosclerotic changes, and (iii) increased volume and (iv) Moya-moya disease. Volumetric flow was measured at the internal carotid artery (ICA) and vertebral artery bilaterally using the velocity-flow diagrams from PC MRI, and combined 4 vessel flows and tCBF were compared among all the groups. RESULTS: The age-specific distribution of tCBFs in normal subjects were as follows: 12.0 +/- 2.1 ml/sec in 18 -29 years group, 11.8 +/- 1.9 ml/sec in 30 -49 years group, 10.9 +/-2.2 ml/sec in 50 -66 years group. The distribution of tCBFs in the different subsets of the abnormal population were as follows: 9.5 +/-2.5 ml/sec in the group with mild reduction in volume, 7.6 +/-2.0 ml/sec in the group with marked reduction in volume, and 7.3 +/-1.2 ml/sec and 7.0 +/- 1.1 ml/sec in the increased parenchymal volume and Moya-moya disease groups respectively. CONCLUSION: Total cerebral blood flow decreases with increasing age with a concomitant reduction in parenchymal volumes and increasing atherosclerotic changes. It is also reduced in the presence of increased parenchymal volume and Moya-moya disease. 2D PC MRI can be used as a tool to evaluate tCBF with aging and in the presence of various conditions that can affect parenchymal volume and cerebral vasculature.

The presence of serum antibodies to various gangliosides, such as anti-GQ1b, is closely related to the clinical features of Guillain-Barre syndrome. However, the phenotype associated with anti-GT1a IgG has not yet been determined, although it has been detected in some cases of the pharyngeal-cervical-brachial variant. We report herein two patients harboring anti-GT1a IgG who both presented with profound dyspnea, dysphagia, and quadriparesis. The findings of this report suggest that the anti-GT1a antibody specifies a clinical feature of oropharyngeal palsy.

Gestational choriocarcinoma is easily disseminated hematogenously and its hypervascular nature places the patient at risk of significant hemorrhage both at the sites of metastatic lesions and in the uterus. In addition, its tends to give rise to pseudoaneurysm formation. Treatment of the condition by percutaneous embolization has been reported in several published articles, and hemoperitoneum secondary to rupture of splenic metastasis of gestational choriocarcinoma has also been reported, as has angiographic embolization. Hemoptysis resulting from pulmonary metastasis and treatment by means of embolization of the bronchial artery have not been reported, however. In this article, we describe a case of hemoptysis and hemoperitoneum due to pulmonary and splenic metastasis of gestational choriocarcinoma. Treatment of the condition involved embolization of the bronchial artery and superselective embolization of the splenic artery.

Drug-induced sleep endoscopy (DISE) is used to identify areas of upper airway obstruction, which occurs when patients with obstructive sleep apnea (OSA) snore. DISE enables effective diagnosis and appropriate treatment of the obstruction site. Among surgical treatment methods for OSA, maxillomandibular advancement surgery (MMA) is performed to move a jaw forward; the surgery has a high success rate for OSA treatment. In DISE, anesthetics such as propofol and midazolam must be administered to induce snoring while the patient is deeply sedated for an accurate diagnosis to be made. When inducing deep sedation in a patient with OSA, airway obstruction may increase, causing oxygen saturation to drop; airway interventions are necessary in such cases. Effective DISE and MMA surgery can be performed by administering propofol through target-controlled infusion while monitoring the bispectral index (BIS).

PURPOSE: Well-differentiated carcinomas of the thyroid run an excellent clinical course. However 10~20% of thyroid carcinomas showed poor clinical outcomes. Insular carcinomas are an uncommon thyroglobulin-producing neoplasm, which show intermediate prognosis between well-differentiated carcinomas and undifferentiated anaplastic carcinomas, and their clinicopathologic features are poorly understood. Therefore, we aimed to investigate the clinicopathologic features and the prognosis of insular thyroid carcinomas. METHODS: We reviewed 10 patients who underwent an operation due to an insular thyroid carcinoma at Seoul National University Hospital between January 1990 and December 2001. Their clinicopathologic features and follow-up findings were retrospectively reviewed and compared. RESULTS: Four male and six female patients are reviewed, with a mean age of 54.8+/-6.4187, ranging from 37 to 69 years. Pathologically, eight of the tumors consisted of pure insular carcinoma and the others showed a papillary carcinoma as the major component and a minor insular component. The mean tumor size was 4.53 cm (4.53+/-1.4288 cm). An extrathyroidal extension was present in 7 cases and a vascular invasion in 6. Distant metastasis and local relapse of the regional lymph node were seen in 9 patients. Comparing the survivor and expired groups, all the male patients were in the expired group, and the mean tumor size was larger in the expired group (5.46 cm vs. 3.6 cm). But these differences were not statistically significant. CONCLUSION: Our study revealed that insular carcinomas have distinctive clinicopathologic features, and recognition of this histologic variant is important and significant for management of these unique tumors.

BACKGROUND: This study retrospectively investigated outcomes following dental implantation in patients with special needs who required general anesthesia to enable treatment. METHODS: Patients underwent implant treatment under general anesthesia at the Clinic for the Disabled in Seoul National University Dental Hospital between January 2004 and June 2017. The study analyzed medical records and radiographs. Implant survival rates were calculated by applying criteria for success or failure. RESULTS: Of 19 patients in the study, 8 were males and 11 were females, with a mean age of 32.9 years. The patients included 11 with mental retardation, 3 with autism, 2 with cerebral palsy, 2 with schizophrenia, and 1 with a brain disorder; 2 patients also had seizure disorders. All were incapable of oral self-care due to serious cognitive impairment and could not cooperate with normal dental treatment. A total of 27 rounds of general anesthesia and 1 round of intravenous sedation were performed for implant surgery. Implant placement was performed in 3 patients whose prosthesis records could not be found, while 3 other patients had less than 1 year of follow-up after prosthetic treatment. When the criteria for implant success or failure were applied in 13 remaining patients, 3 implant failures occurred in 59 total treatments. The cumulative survival rate of implants over an average of 43.3 months (15-116 months) was 94.9%. CONCLUSIONS: For patients with severe cognitive impairment who are incapable of oral self-care, implant treatment under general anesthesia showed a favorable prognosis.

Angiomyolipomas commonly originate from renal parenchyma but extremely rarely from perinephric space. We report a case of angiomyolipoma of the perinephric space confirmed by radical nephrectomy. A 13-year-old boy presented with left flank pain and abdominal distension, first experienced five months earlier. Ultrasonography and CT indicated that in the space surrounding the left kidney, a huge fat-containing mass with linear strands was present.

A congenital hepatoportal arteriovenous fistula associated with an intrahepatic portal vein aneurysm is a rare type of arteriovenous malformation. Only 14 pediatric cases have been reported to the best of the authors' knowledge. An intrahepatic shunt between the portal and systemic veins is also relatively rare. We report a case of a congenital hepatoportal arteriovenous fistula associated with an intrahepatic portal vein aneurysm and a portohepatic venous shunt in a neonate who presented with tachypnea and melena.
