    ABSTRACT: Abstract Purpose: To investigate the prevalence of Toxoplasma gondii and Toxocara canis in patients with uveitis. Methods: Patients with uveitis were examined. Serum antibodies to T. gondii and T. canis were tested by using the enzyme-linked immunosorbent assay. Polymerase chain reaction (PCR) was done using blood and aqueous humor (AH). Results: Ninety-eight patients were enrolled. Mean age was 43.5 ± 13.2 years. Six patients were seropositive for T. gondii with the following pattern: anterior uveitis, 1; posterior uveitis with retinitis, 2; pan uveitis, 2. One patient had a positive PCR result for T. gondii in AH, who showed panuveitis. Twenty-three patients were positive to serum IgG for T. canis with the following clinical manifestation: granuloma, 6; pigmented scar, 3; vitritis, 6-but none were PCR positive. Conclusions: T. gondii and T. canis are still important causes of uveitis. Ocular toxocariasis is not an uncommon cause of uveitis, even in adults.

    ABSTRACT: Toxoplasma gondii is a zoonotic parasite resulting in human infections and one of the infectious pathogens leading to uveitis and retinochoroiditis. The present study was performed to assess T. gondii infection in 20 ocular patients with chronic irregular recurrent uveitis (20 aqueous humor and 20 peripheral blood samples) using PCR. All samples were analyzed by nested PCR targeting a specific B1 gene of T. gondii. The PCR-positive rate was 25% (5/20), including 5% (1) in blood samples, 25% (5) in aqueous humor samples, and 5% (1) in both sample types. A molecular screening test for T. gondii infection in ocular patients with common clinical findings of an unclear retinal margin and an inflammatory membrane over the retina, as seen by fundus examination, may be helpful for early diagnosis and treatment.

    ABSTRACT: PURPOSE: To evaluate the efficacy of vitrectomy including internal limiting membrane (ILM) peeling without gas tamponade for myopic foveoschisis (MF). METHOD: In this retrospective study, 15 eyes of 13 consecutive patients with MF underwent pars plana vitrectomy and ILM peeling without gas tamponade. The main outcomes were measured using best-corrected visual acuity (BCVA) and central macular thickness (CMT) on optical coherence tomography (OCT). RESULT: The mean refractive error was -11.0 ± 8.2 diopters and mean axial length was 30.8 ± 2.6 mm. The mean BCVA increased from 0.78 ± 0.53 to 0.61 ± 0.75 logMAR unit (p = 0.05), and the mean CMT decreased from 405 ± 143 μm to 255 ± 47 μm (p = 0.002) during a follow-up of 11.8 months. OCT showed a complete resolution of the MF, with foveal reattachment in all eyes. Full-thickness macular hole developed in two eyes during follow-up. CONCLUSION: ILM peeling without gas tamponade results in favorable anatomical and visual outcomes.

    ABSTRACT: This study compared outcomes in children with acute leukemia who underwent transplantations with umbilical cord blood (UCB), bone marrow, or peripheral blood stem cells from a human leukocyte antigen (HLA)-matched related donor (MRD) or an unrelated donor (URD). This retrospective study included consecutive acute leukemia patients who underwent their first allogeneic hematopoietic stem cell transplantation (HSCT) at Samsung Medical Center between 2005 and 2010. Patients received stem cells from MRD (n=33), URD (n=46), or UCB (n=41). Neutrophil and platelet recovery were significantly longer after HSCT with UCB than with MRD or URD (P<0.01 for both). In multivariate analysis using the MRD group as a reference, the URD group had a significantly higher risk of grade III to IV acute graft-versus-host disease (GVHD; relative risk [RR], 15.2; 95% confidence interval [CI], 1.2 to 186.2; P=0.03) and extensive chronic GVHD (RR, 6.9; 95% CI, 1.9 to 25.2; P<0.01). For all 3 donor types, 5-year event-free survival (EFS) and overall survival were similar. Extensive chronic GVHD was associated with fewer relapses (RR, 0.1; 95% CI, 0.04 to 0.6; P<0.01). Multivariate analysis showed that lower EFS was associated with advanced disease at transplantation (RR, 3.2; 95% CI, 1.3 to 7.8; P<0.01) and total body irradiation (RR, 2.1; 95% CI, 1.0 to 4.3; P=0.04). Survival after UCB transplantation was similar to survival after MRD and URD transplantation. For patients lacking an HLA matched donor, the use of UCB is a suitable alternative.

    ABSTRACT: Cisplatin-based chemotherapy has been commonly used for the treatment of intracranial germ cell tumors (IC-GCTs). However, this treatment exhibits some adverse effects such as renal problems and hearing difficulty. Carboplatin-based chemotherapy was administered to pediatric patients with IC-GCTs from August 2004 at the Samsung Medical Center. In this study, we assessed the responses and adverse effects of carboplatin-based chemotherapy in pediatric IC-GCTs patients according to the risk group, and compared the results with those of the previous cisplatin-based chemotherapy. We examined 35 patients (27 men and 8 women) diagnosed with IC-GCTs between August 2004 and April 2008 and received risk-adapted carboplatin-based chemotherapy at the Samsung Medical Center. Patients were divided into either low-risk (LR) or high-risk (HR) groups and a retrospective analysis was performed using information from the medical records. Although hematological complications were common, hearing difficulties or grade 3 or 4 creatinine level elevation were not observed in patients who underwent carboplatin-based chemotherapy. The frequency of febrile neutropenia did not differ between the risk groups. The overall survival was 100% and event-free survival (EFS) was 95.7%. The EFS rate was 100% in the LR group and 90% in the HR group, respectively. Despite their common occurrence in high-risk patients, no lethal hematological complications were associated with carboplatin-based treatment. The current carboplatin-based chemotherapy protocol is safe and effective for the treatment of pediatric patients with IC-GCTs.

    ABSTRACT: The risk of invasive fungal infection is greater for allogeneic hematopoietic stem cell transplantation (HSCT) than for autologous transplantation. Therefore, many transplantation centers use antifungal prophylaxis for allogeneic HSCT, however, there exists no standard guidelines or consensus regarding autologous HSCT. A prospective double-blind randomized study was conducted in autologous HSCT recipients who were divided into prophylaxis and empirical treatment groups, and we investigated the efficacy of itraconazole prophylaxis in pediatric autologous HSCT. Total 87 autologous HSCT episodes in 55 children with high-risk solid tumors were studied. No invasive fungal infections occurred in either group. However, patients in the prophylaxis group had a significantly shorter duration of fever (p < 0.05) and received antibacterial treatment of shorter duration (p < 0.05) with fewer numbers of antibiotics (p < 0.05 for the use of second line antibiotics) than those in the empirical group. No significant additional adverse events were found with itraconazole prophylaxis. Although beneficial effects such as a shorter duration of fever and reduced need for antibiotic use were observed in the prophylaxis group, the results were not sufficient to draw a definite recommendation about the routine use of antifungal prophylaxis in pediatric autologous HSCT recipients with high-risk solid tumors (Trial registration: NCT00336531).

    ABSTRACT: Chronic perineal pain is an often encountered problem, which produces a great degree of functional impairment and frustration to the patient and a challenge to the treating physician. The reason for this problem is that the region contains diverse anatomic structures with mixed somatic, visceral and autonomic innervations affecting bladder and bowel control and sexual function. A blockade of nociceptive and sympathetic supply to the perineal region, supplied through the ganglion impar has been shown to benefit patients with chronic perineal pain. Several options to this block have been described that chemical neurolysis, radiofrequency ablation etc. Although the analgesic effect of Botulinum toxin type A (BoNT-A) has long been considered secondary to its action for muscle relaxation, BoNT-A also affects the release of the neurotransmitters that are involved in pain perception. We describe a patient who was successfully given ganglion impar block with BoNT-A.

    ABSTRACT: Complications following lumbar transforaminal epidural injection are frequently related to inadvertent vascular injection of corticosteroids. Several methods have been proposed to reduce the risk of vascular injection. The generally accepted technique during epidural steroid injection is intermittent fluoroscopy. In fact, this technique may miss vascular uptake due to rapid washout. Because of the fleeting appearance of vascular contrast patterns, live fluoroscopy is recommended during contrast injection. However, when vascular contrast patterns are overlapped by expected epidural patterns, it is hard to distinguish them even on live fluoroscopy. During 87 lumbar transforaminal epidural injections, dynamic contrast flows were observed under live fluoroscopy with using digital subtraction enhancement. Two dynamic fluoroscopy fluoroscopic images were saved from each injection. These injections were performed by five physicians with experience independently. Accuracy of live fluoroscopy was determined by comparing the interpretation of the digital subtraction fluoroscopic images. Using digital subtraction guidance with contrast confirmation, the twenty cases of intravascular injection were found (the rate of incidence was 23%). There was no significant difference in incidence of intravascular injections based either on gender or diagnosis. Only five cases of intravascular injections were predicted with either flash or aspiration of blood (sensitivity = 25%). Under live fluoroscopic guidance with contrast confirmation to predict intravascular injection, twelve cases were predicted (sensitivity = 60%). This finding demonstrate that digital subtraction fluoroscopic imaging is superior to blood aspiration or live fluoroscopy in detecting intravascular injections with lumbar transforaminal epidural injection.

    ABSTRACT: The purpose of this study was to evaluate the effectiveness of intravitreal injection of bevacizumab for treatment of central serous chorioretinopathy. In this retrospective case series, six patients (six eyes) with central serous chorioretinopathy were treated with an intravitreal injection of bevacizumab. The outcome measures included visual acuity with Early Treatment Diabetic Retinopathy Study letters, central macular thickness measurement with optical coherence tomography, changes in fluorescein angiography, and indocyanine green angiography. The mean age of the patients was 42.3 years and the mean follow-up period was 9.0 months (range, 5-12 months). Mean visual acuity +/- standard deviation increased from 40.8 +/- 8.3 Early Treatment Diabetic Retinopathy Study letters at baseline to 49.0 +/- 5.0 Early Treatment Diabetic Retinopathy Study letters at 1 month (P = 0.046) and to 53.3 +/- 5.2 Early Treatment Diabetic Retinopathy Study letters at 3 months (P = 0.028). Mean central macular thickness +/- standard deviation decreased from 331.5 +/- 93.4 microm to 164 +/- 34 microm at 3 months (P = 0.043). Leakage on fluorescein angiography and hyperpermeability on indocyanine green angiography decreased in conjunction with improvement in central macular thickness observed by optical coherence tomography. Intravitreal bevacizumab injections resulted in improved visual acuity and anatomical results for central serous chorioretinopathy.

    ABSTRACT: To evaluate the changes in aqueous humor cytokine levels following consecutive intravitreal bevacizumab (Avastin, Genentech Inc., San Francisco, CA, USA) injections in eyes with choroidal neovascularization (CNV) due to age-related macular degeneration (AMD). Aqueous humor samples were collected at the time of intravitreal injection of 1.25 mg of bevacizumab every 7.0 (+/-2.0) weeks from ten eyes with AMD for the AMD group and during cataract surgery in nine eyes for the control group. Visual acuity with Early Treatment of Diabetic Retinopathy Study (ETDRS) letters and central macular thickness (CMT) using optical coherence tomography were measured before each injection in the AMD group. Aqueous cytokine levels were determined by immunoassay using multi-analyte biochip array technology (Evidence investigator cytokine and growth factor biochip array, RANDOX laboratories Ltd., Crumlin, UK). In the AMD group, mean +/- standard deviation(SD) aqueous VEGF levels decreased from 68.0 +/- 32.1 pg/ml at baseline to 26.3 +/- 19.0 pg/ml after the first injection (p = 0.028) and to 25.2 +/- 12.8 pg/ml after the second injection (p = 0.005). While CMT decreased from 307.7 +/- 102.0 mum to 206.8 +/- 141.5 microm (p = 0.037), ETDRS visual acuity increased from 17.6 +/- 11.7 letters to 22.0 +/- 15.6 letters after three consecutive injections (p = 0.017). Significantly decreased VEGF levels were noted after the first injection of bevacizumab. These levels were maintained after the second injection, which paralleled the change in visual acuity and CMT.

    ABSTRACT: The role of coronary calcium scoring in coronary risk estimation is not well established. Calcium scoring could provide additional information in a certain subgroup of patients where the calcium score does not match the conventional Framingham risk estimates. We explored the characteristics of such a subgroup. The study participants were 1653 asymptomatic persons who underwent routine health screening and calcium scoring using the 16-slice multidetector computed tomography. Risk stratification was performed in five categories both by 10-year Framingham coronary risk and the Agatston coronary calcium score. Risk stratifications by coronary calcium score and absolute risk showed a large discrepancy (difference > or =3 classes) in about 9% of participants. The proportion increased with age (P for trend <0.0001). An exploratory analysis revealed that age (partial R=0.109, P<0.0001) and the presence of the metabolic syndrome (partial R=0.025, P<0.001) were independent variables that accounted for the variance of the residual of regression between the log-transformed value of coronary calcium score and the absolute risk. Calcium scoring may be clinically more useful in older (> or =50 years) participants and/or in participants with the metabolic syndrome because of the relatively higher probability of obtaining additional information that the conventional Framingham risk estimation cannot provide.
