OBJECTIVE: Endovascular coiling of ruptured tiny aneurysms (RTAs) in the brain has been known to be technically challenging owing to the higher rate of adverse events, such as thromboembolism and intraoperative rupture. The aim of this study was to report our ex-periences of endovascular treatment of RTAs (size, ≤3 mm).METHODS: From January 2006 to December 2017, 35 RTAs in 35 patients were treated at our institution with an endosaccular coiling. Procedural data and clinical and angiographic results were retrospectively reviewed.RESULTS: The mean size of the RTAs was 2.53 mm (SD: 0.38). The neck remodeling technique was applied to 14 aneurysms, including stent-assisted coiling (n=7) and balloon-assisted coiling (n=7). Procedure-related complications included intraprocedural rupture (n=2), thromboembolic event (n=1), and early rebleeding (n=2), which needed recoiling. Regarding immediate angiographic control, complete occlusion was achieved in 25 aneurysms (71.4%), small neck remnant in 5 (14.3%), and definite remnant in 5 (14.3%). At the end of follow-up, 31 of the 35 patients (88.6%) were able to function independently. Twenty-two of the 35 patients underwent follow-up conventional angiography (mean, 468 days). Stable occlusion was achieved in 20 of the 22 patients (90.9%), minor recanalization in 1 (4.5%), and major recanalization, which required recoiling, in 1 (4.5%).CONCLUSION: Our experiences demonstrate that endovascular treatment for RTAs is both feasible and effective. However, periprocedural rebleedings were found to occur more often (11.4%) than what is generally suspected.

OBJECTIVE: Aneurysms arising from the pericallosal artery (PA) are uncommon and challenging to treat. The aim of this study was to report our experiences of the endovascular treatment of ruptured PA aneurysms. METHODS: From September 2003 to December 2013, 30 ruptured PA aneurysms in 30 patients were treated at our institution via an endovascular approach. Procedural data, clinical and angiographic results were retrospectively reviewed. RESULTS: Regarding immediate angiographic control, complete occlusion was achieved in 21 (70.0%) patients and near-complete occlusion in 9 (30.0%). Eight procedure-related complications occurred, including intraprocedural rupture and early rebleeding in three each, and thromboembolic event in two. At last follow-up, 18 patients were independent with a modified Rankin Scale (mRS) score of 0-2, and the other 12 were either dependent or had expired (mRS score, 3-6). Adjacent hematoma was found to be associated with an increased risk of poor clinical outcome. Seventeen of 23 surviving patients underwent follow-up conventional angiography (mean, 16.5 months). Results showed stable occlusion in 14 (82.4%), minor recanalization in two (11.8%), and major recanalization, which required recoiling, in one (5.9%). CONCLUSION: Our experiences demonstrate that endovascular treatment for a ruptured PA aneurysms is both feasible and effective. However, periprocedural rebleedings were found to occur far more often (20.0%) than is generally suspected and to be associated with preoperative contrast retention. Analysis showed existing adjacent hematoma is predictive of a poor clinical outcome.

Leptospirosis is a spirochetal infectious disease caused by Leptospira interrogans, and may vary in degree from an asymptomatic infection to a severe and fatal illness. The kidney is one of the principal target organs of Leptospira. Renal disorders caused by Leptospira infection vary from an abnormality in urinalysis to acute kidney injury (AKI). Incidence of AKI in severe leptospirosis varies from 40% to 60%. AKI reflects the severity of leptospirosis and is generally accompanied by cholestatic jaundice. The pathophysiology of AKI in leptospirosis consists of hypovolemia, direct tubular toxicity, and rhabdomyolysis. Most patients with acute leptospirosis experience severe myalgias, and show laboratory evidence of mild rhabdomyolysis. However, occurrence of severe rhabdomyolysis is rare. We report here on a patient with leoptospirosis, who had severe rhabdomyolysis and acute kidney injury without jaundice.

PURPOSE: To report a rare case of recurrent alveolar soft-part sarcoma (ASPS) with concurrent involvement of the orbit and multiple sites of the body that was removed successfully by surgery. CASE SUMMARY: A 37-year-old woman presented with diplopia at the left lateral gaze and proptosis of the left eye. Two years earlier, the patient had a mass excision of the right gluteus maximus and the left orbit, and ASPS was histopathologically diagnosed at that time. In addition, the patient had been treated with chemotherapy and radiation therapy. On radiologic examination, recurrent tumor of the left orbit was found and surgically removed. The histopathologic examination showed that tumor cells were arranged in an alveolar pattern divided by fibrous septa and contained abundant granules in the cytoplasm, typically consistent with ASPS. Postoperatively, the symptoms of diplopia and proptosis improved. CONCLUSIONS: ASPS can occur and recur in the orbit as well as systemically. In addition, at the time of surgical removal of ASPS in the orbit, the surgeon should be particularly cautious of massive bleeding.

PURPOSE: We evaluated various preoperative anterior segment parameters measured with a Pentacam rotating Scheimpflug camera and compared them with those of conventional methods. We also evaluated the effect of different parameters on corneal endothelial cells after cataract surgery. METHODS: Pentacam examination was performed in 88 eyes from 88 patients to evaluate central anterior chamber depth (ACD(pentacam)), nuclear density (Densitometry(pentacam)), anterior chamber volume (ACV), and lens thickness (LT(pentacam)). We compared values of ACD(pentacam) with those of ultrasound (ACD(sono)) and also compared Densitometry(pentacam) values with those of Lens Opacities Classification System (LOCS III) classification. We evaluated the effect of the following preoperative values measured with Pentacam on postoperative endothelial cell loss: pupil size measured both preoperatively and before capsulorrhexsis (Pupil(CCC)), amount of viscoelastics, and LT measured by ultrasound (LT(sono)). RESULTS: A significant concordance was found between the two grading methods of nuclear opacity: Densitometry(pentacam) and LOCS III classification (tau(b) = 0.414, p = 0.000). We also found a positive correlation between ACD(pentacam) and ACD(sono) (r = 0.823, p = 0.000) and between ACD(pentacam) and ACV (r = 0.650, p = 0.000). There were significant differences between the results of LT(pentacam) and LT(sono). The final regression model identified Densitometry(pentacam), viscoelastics and Pupil(CCC) as independent predictors of decreased postoperative corneal endothelial cell density (CD) at postoperative day 3, and Densitometry(pentacam), viscoelastics, and ACV as independent predictors of decreased CD two months postoperatively (p<0.05). CONCLUSIONS: Good agreement was found between all results obtained with the Pentacam and conventional methods except LT. Analyzing anterior chamber parameters preoperatively using Pentacam could be helpful to predict postoperative endothelial cell loss.

PURPOSE:Yellow fever, a mosquito-borne viral hemorrhagic fever, is one of the most lethal diseases. Recently there have been an increasing number of Korean children who have travelled to yellow fever endemic zones and were administered yellow fever vaccine (YFV). Therefore, we carried out this study to provide child travelers with safety information of YFV. METHODS:This study was conducted at the International Clinic of National Medical Center in Seoul between April 2007 and June 2008 for the evaluation of adverse events of YFV. One hundred twenty- five children received YFV (17-DD) and were prospectively monitored for adverse events through telephone interviews on day 3, 6, 9, 16, 23 and 30 after vaccination. RESULTS:Adverse events were observed in 31 (24.8%) of 125 child travelers who received the YFV. The mean age was 12.5+/-5.0 years. Sixty-six of the child travelers (52.8%) were males. The common adverse events were pain in 11 (8.8%), swelling in 8 (6.4%) and redness in 7 children (5.6%) at the injection site. The systemic adverse events included mild fever in 5 (4.0%), headache in 5 (4.0%), cough in 4 (3.2%), abdominal pain in 3 (2.4 %), and vomiting in 2 children (1.6%). Most of the adverse events were detected within 7 days of administration and there were no differences in adverse events by gender or age. All travelers who had complained of symptoms improved spontaneously or following symptomatic treatment. CONCLUSION:This study showed that YFV is well-tolerated and there were no reports of severe adverse events. Studies are ongoing to clarify the cause and risk factors for rare adverse events.

PURPOSE: This paper compares a RSS (Rapid Streptococcal Screening) detection test with a throat culture. The RSS detection kit is an easier and faster way to identify the infection of Group A beta-hemolytic streptococcus (GABHS), the most common causal agent of acute bacterial pharyngitis. We also examine the clinical symptoms that are associated with bacterial pharyngitis. METHODS: A throat culture and a RSS detection test were performed simultaneously to all 239 patients who were suspected of having acute pharyngitis, and visited the emergency department between September 1st, 2002, and June 30th, 2003. Then the values of the RSS detection test were analyzed comparatively on a chi square test. The correlation between Centor criteria clinical features and bacterial pharyngitis was examined through a logic regression test. RESULTS: Comparative analysis of the results of a throat culture and RSS detection test showed a test sensitivity of 83.6%, specificity was 97.2%, and the kappa coefficient was 0.83 (95% C.I: 0.75~0.91). This suggests that the RSS detection test is valuable statistically. CONCLUSION: The RSS detection test is more accurate than the diagnosis of bacterial pharyngitis based on clinical features. Assuming that all patients with acute pharyngitis take antibiotics, an RSS detection test reduce of unnecessary antibiotics use.

Peritonitis is one of the major complications of CAPD (continuous ambulatory peritoneal dialysis). Among its causative organisms, vancomycin-resistant enterococcus (VRE) is rare, but serious causative organism, because it is refractory to antibiotics commonly used for CAPD peritonitis. Some drugs such as linezolid and dalfopristin have been introduced for VRE infections nowadays, but reports about usefulness of those drugs in VRE peritonitis are rare. We experienced a case of CAPD peritonitis caused by VRE, which was treated successfully with removal of CAPD catheter and use of linezolid. We report our experience with review of the literature.

PURPOSE: Contralateral jugular lymph node metastasis (CJLNM) of papillary thyroid cancer (PTC) is rarely found during operative procedures. HoweverPTC is being diagnosed with increasing frequency and lymph node metastasis is now recognized as a factor of prognosis and recurrence. Therefore, this study was conducted to evaluate the clinical and histological characteristics of papillary thyroid cancer and to determine the factors that lead to CJLNM. METHODS: Two-hundred patients with PTC were treated in our hospital between March 2005 and October 2006. A retrospective analysis of the patient's clinical and histological features and lymph node metastasis was conducted. RESULTS: The total ratio of CJLNM to PTC was approximately 7.5%, the male to female ratio was 1:6.5, and the mean tumor size was 14.93 mm. In addition, the multiplicity was 53.3% and the bilatrality was 53.3%. Further, there were 4 cases involving benign thyroid disease combined with goiter. In addition, the capsule invasion was 100%. Age under 40 years, bilaterality and capsule invasion were found to be significant clinicopathologic factors of CJLNM induced by PTC. CONCLUSION: A contralateral jugular lymph node biopsy of PTC may be considered in cases involving patients under 40 years of age with, bilaterality and capsular invasion.
