Journal of the Korean Ophthalmological Society 2023;64(2):158-163
Purpose:
To report recurrent idiopathic choroidal neovascularization (CNV) in an adolescent.Case summary: A 14-year-old male presented with reduced vision in the right eye, 3 weeks in duration. His best-corrected visual acuity (BCVA) was 0.2. He lacked any medical or ocular history, any family history of retinal disease, and any trauma history. Autorefraction yielded a spherical equivalent of -4.75 diopters. Neither posterior staphyloma nor myopic macular degeneration was apparent in a fundus photograph. However, the photograph revealed a greyish foveal lesion with a subretinal hemorrhage, but was otherwise unremarkable. Optical coherence tomography and fluorescein angiography revealed foveal CNV with a subretinal hemorrhage and fluid. As no feature known to cause CNV was apparent, we diagnosed idiopathic CNV and prescribed right-eye intravitreal ranibizumab injections. After treatment, the BCVA became 1.0, but the CNV continued to recur; he has received 26 intravitreal ranibizumab injections over the last 47 months.
Conclusions
Most idiopathic CNVs in adolescents are well-treated with fewer injections. However, CNV can continue to recur; multiple intravitreal injections and careful monitoring may be required.

Purpose:
The results of the Hahn Chun Suk color test (Hahn test) and the Farnsworth-Munsell D-15 test (D-15 test) were compared in patients with acute optic neuritis.
Methods:
Patients with acute optic neuritis evaluated using both the Hahn and D-15 tests in the acute phase and 2 months later were evaluated. The results of the acute phase tests were compared. Correlations were sought between color deficiency and all of visual acuity, the visual field index (VFI), and the severity of optic disc edema. Changes in the test results 2 months later were also evaluated and correlated with other visual functions.
Results:
Twenty-seven eyes of 22 patients were enrolled. The mean patient age was 49.4 years and the logarithm of the minimum angle of resolution visual acuity 0.5. In the acute phase, the perception number was 10.06 in the Hahn test. On the D-15 test, the ‘strong’ grade predominated (40.7%). The concordance rates of severity and type were 55.6 and 54.5% between the two tests. In 9 of 12 eyes exhibiting inconsistent severity, the D-15 test afforded better results than did the Hahn test. A significant positive correlation was evident between the Hahn test results and visual acuity (r = 0.560, p = 0.002). The mean deviation (MD) and the VFI also correlated with the results of the Hahn test (r = -0.432, p = 0.027 for the MD; r = -0.517, p = 0.007 for the VFI). The D-15 test results correlated only with visual acuity (r = 0.476, p = 0.012). After 2 months, the results of both tests correlated significantly only with visual acuity.
Conclusions
In the acute phase, the concordances of the Hahn and D-15 test results were 55.6% in terms of severity and 54.5% in terms of type. The Hahn test results correlated with the visual acuity and VFI. In contrast, the D-15 test results correlated with visual acuity only.

Background:
This clinical trial was conducted to determine whether combined use of magnesium sulfate and vitamin C more significantly reduced postoperative fentanyl consumption and pain than magnesium sulfate or vitamin C alone.
Methods:
The prospective, double-blinded, randomized controlled study enrolled 132 patients scheduled for laparoscopic gynecologic surgery. The patients were randomly allocated to one of the four groups (n = 33 for each group; Group M [magnesium sulfate 40 mg/kg], Group V [vitamin C 50 mg/kg], Group MV [magnesium sulfate 40 mg/kg and vitamin C 50 mg/kg] and Group C [isotonic saline 40 ml]). Cumulative postoperative fentanyl consumption (primary endpoint measure), postoperative pain score by numeric rating scale, and postoperative nausea and vomiting were recorded at 1, 6, 24, and 48 h after discharge from the postanesthesia care unit.
Results:
Cumulative postoperative fentanyl consumption was significantly less in Groups M, V, and MV than in Group C at all time points. Group MV showed significantly less cumulative postoperative fentanyl consumption than Group M at postoperative 24 h (mean ± standard deviation, 156.6 ± 67.5 vs. 235.6 ± 94.6 μg, P = 0.001), as well as significantly less consumption than Groups M and V at postoperative 48 h (190.8 ± 74.6 vs. 301.0 ± 114.8 or 284.1 ± 128.6 μg, P < 0.001, P = 0.003, respectively).
Conclusions
Combined use of magnesium sulfate and vitamin C provides an additional benefit in postoperative pain management after laparoscopic gynecologic surgery in comparison to single administration of magnesium sulfate or vitamin C.

PURPOSE: To evaluate the effect of intravitreal aflibercept according to subfoveal choroidal thickness in patients with polypoidal choroidal vasculopathy (PCV). METHODS: We retrospectively analyzed the medical records of 60 eyes from 60 patients with PCV treated with intravitreal aflibercept. The patients were followed for at least 6 months after the first injection. Using software, subfoveal choroidal thickness was manually measured as the distance from the hyper-reflective line of Bruch's membrane to the chorioscleral interface on optical coherence tomography. The patients were divided into three groups based on subfoveal choroidal thickness. Visual acuity, subfoveal choroidal thickness, central macular thickness and largest pigment epithelial detachment (PED) height, polyp regression rate, and dry macula rate were evaluated to analyze the anatomical and functional outcomes. RESULTS: Baseline mean subfoveal choroidal thickness were 178.50 ± 28.42 µm in the thin group (14 eyes, 23.3%), 287.03 ± 43.58 µm in the medium group (33 eyes, 55.0%), and 379.77 ± 17.09 µm in the thick group (13 eyes, 21.7%). Baseline age, sex, visual acuity, central macular thickness, and the largest PED height did not differ significantly among the three subgroups. Only the thin group showed significant improvement of visual acuity at 6 months (p = 0.005). Subfoveal choroidal thickness, central macular thickness, and largest PED height were significantly decreased after treatment in all subgroups and did not differ among the subgroups. Compared with the other groups, the thin subfoveal choroidal thickness group showed higher polyp regression rate at 3 months and higher dry macula rate at 6 months (p = 0.013 and p = 0.004, respectively). CONCLUSIONS: Intravitreal aflibercept injection was effective for the treatment of PCV, and thin subfoveal choroidal thickness was associated with better anatomical and functional outcomes.

Localized tenosynovial giant cell tumor (TGCT) usually occurs in the hand and foot regions. However, localized TGCT with extensive cartilaginous metaplasia is rare, especially in the tendon sheath of the toe. Here, we report a case of localized TGCT with cartilaginous metaplasia in a 57-year-old man. The tumor presented as a lobular mass measuring 2.2 cm in its greatest dimension and arose in the flexor digitorum tendon sheath of the right 2nd toe. Clinically, the mass was palpable 1 year ago and brought pain during walking. Microscopically, the mass was composed of focal conventional TGCT and cartilaginous components. The conventional TGCT areas consisted of mononuclear cells, multinucleated giant cells, and hemosiderin deposition. The chondroid areas were extensive and comprised more than 90% of the whole tumor. In this case, the mononuclear cells in the conventional TGCT areas showed focal immunohistochemical staining for podoplanin and S100 protein as well as diffuse staining for CD68, which is consistent with the staining pattern of conventional TGCT. The mononuclear cells in the chondroid areas were focal positive for podoplanin and diffuse positive for S100 protein. Chondroid metaplasia in diffuse TGCT has been reported in 10 cases involving the temporomandibular, elbow, and hip joints. However, there has been no report of a localized form of chondroid TGCT involving an extra-articular region.

BACKGROUND/AIMS: This study investigated the expression of nuclear factor kappaB (NF-kappaB) and the chemokine receptor (CXCR4) in patients with diffuse large B-cell lymphoma (DLBCL) who received rituximab-based therapy. METHODS: Seventy patients with DLBCL and treated with rituximab-CHOP (R-CHOP) were included, and immunohistochemistry was performed to determine the expression of NF-kappaB (IkappaB kinase alpha, p50, and p100/p52) and CXCR4. To classify DLBCL cases as germinal center B-cell-like (GCB) and non-GCB, additional immunohistochemical expression of CD10, bcl-6, or MUM1 was used in this study. The expression was divided into two groups according to the intensity score (negative, 0 or 1+; positive, 2+ or 3+). RESULTS: The median age of the patients was 66 years (range, 17 to 87), and 58.6% were male. Twenty-seven patients (38.6%) had stage III or IV disease at diagnosis. Twenty-three patients (32.9%) were categorized as high or high-intermediate risk according to their International Prognostic Indexs (IPIs). The overall incidence of bone marrow involvement was 5.7%. Rates of positive NF-kappaB and CXCR4 expression were 84.2% and 88.6%, respectively. High NF-kappaB expression was associated with CXCR4 expression (p = 0.002), and 56 patients (80.0%) showed coexpression. However, the expression of NF-kappaB or CXCR4 was not associated with overall survival and EFS. On multivariate analysis that included age, gender, performance status, stage, and the IPI, no significant association between the grade of NF-kappaB or CXCR4 expression and survival was observed. CONCLUSIONS: The current study suggests that the tissue expression of NF-kappaB and CXCR4 may not be an independent prognostic marker in DLBCL patients treated with R-CHOP.

PURPOSE: This study investigated the impact of subclinical borderline changes on the development of chronic allograft injury in patients using a modern immunosuppression protocol. METHODS: Seventy patients with stable renal allograft function and who underwent protocol biopsies at implantation, 10 days and 1 year after transplantation were included and classified based on biopsy findings at day 10. The no rejection (NR) group included 33 patients with no acute rejection. The treatment (Tx) group included 21 patients with borderline changes following steroid pulse therapy, and the nontreatment (NTx) group included 16 patients with borderline changes nontreated. RESULTS: The Banff Chronicity Score (BChS) and modified BChS (MBChS) were not different among the three groups at implantation (P = 0.48) or on day 10 (P = 0.96). Surprisingly, the NTx group had more prominent chronic scores at the 1-year biopsy, including BChS (3.07 +/- 1.33, P = 0.005) and MBChS (3.14 +/- 1.41, P = 0.008) than those in the Tx and NR group, and deterioration of BChS was more noticeable in the NTx group (P = 0.037), although renal function was stable (P = 0.66). No difference in chronic injury scores was observed between the Tx and NR groups at the 1-year biopsy. CONCLUSION: Subclinical borderline changes can be a risk factor for chronic allograft injury and should be considered for antirejection therapy.

BACKGROUND: Several studies reported that sub-clinical rejection (SCR) detected by a protocol biopsy soon after renal transplantation does permanent damage to a renal allograft, contributing to chronic allograft nephropathy (CAN). This article investigated the risk factors involved in SCR and the effects of treating SCR, and evaluated the clinical significance of a protocol biopsy soon after renal transplantation. METHODS: From January 2007 to June 2010, 253 patients received renal transplantation. Patients were divided into two groups according to whether or not they had undergone a protocol biopsy. To analyze the effect of SCR treatments, patients who were diagnosed with SCR were divided into two groups according to whether or not they had been treated with SCR. The patients who did not undertake a protocol biopsy were included in the untreated groups. RESULTS: Among 138 patients who undertook protocol biopsies, 65 patients (47.1%) showed SCR. In univariate analysis, both the number of HLA-DR mismatches (P=0.003) and not using Simulect (P=0.01) were identified as risk factors of SCR. In multivariate analysis, not using Simulect (P=0.006) was identified as an risk factor independent of SCR. deltaGFR, subtracting GFR at 1 week from GFR at that point, showed significant differences between SCR-treated patients and untreated patients at 1, 3, 6, 9, 12, 24, and 36 months with a P value of less than 0.05. CONCLUSIONS: A protocol biopsy can detect SCR, especially in patients with risk factors such as a high number of HLA mismatches or not using Simulect. Treatment of SCR detected by protocol biopsy will help to improve long-term renal function.

A successful transplantation, across a positive crossmatch barrier, is one of the most persistent long- standing problems in the field of kidney transplant medicine. The aim of this study was to describe seven consecutive living renal transplantations in recipients with positive crossmatch for donors or positive for donor specific antibodies (DSAs). A preconditioning regimen including plasmapheresis and intravenous immunoglobulin was delivered three times a week until the crossmatch and/ or DSAs became negative. Mycophenolate mofetil and tacrolimus were started two days before the plasmapheresis. The protocol was modified to include administration of anti-CD 20 antibody (rituximab, 375 mg/m(2)) from the patient number 3 through the patient number 7. All seven patients achieved negative conversion of the crossmatch or DSAs, and the kidney transplantations were successfully performed in all cases. Acute cellular rejection occurred in two patients, which were subclinical and controlled with high dose steroid treatment. Antibody-mediated rejection occurred in one patient, which was easily reversed with plasmapheresis. All recipients attained normal graft function during the 7-24 months of follow up. Our study suggests that sensitized patients can be transplanted successfully with desensitization pretreatment.
