The cutaneous metastaaes from carcinoma of breast produce four definite clinical types: inflammatory carcinoma, telangiectatic carcinoma, nodular carcinoma, and carcinoma en cuirasse. We present a case of 51-year-old woman who had purpuric, hard, sclerotic plaque with ulceration, crust and. several pea-sized hemorrhagic papulovesicular eruptions on the right chest wall for one year. Histopathological findings show metastatic ductal carcinoma but, the primary focus was not determined.

Journal of Korean Medical Science 2021;36(31):e227-
Background:
Coronavirus disease 2019 (COVID-19) vaccination is necessary to reach herd immunity and essential for mitigating the spread of the pandemic. In May 2021, the US FDA and the EU have expanded the emergency use authorization for a COVID-19 vaccine to children aged 12 to 15. The aim of this study was to investigate parental acceptability of COVID-19 vaccination for their children, factors affecting their acceptability, and children's perceptions of COVID-19 vaccines in Republic of Korea.
Methods:
We conducted a questionnaire survey at two tertiary hospitals from May 25, 2021 to June 3, 2021. Subjects were parents having children under 18 years and children aged 10–18 years.
Results:
Two hundred twenty-six parents and 117 children aged 10–18 years were included in the final analysis. Overall, 76.5% and 64.2% of parents intended to get vaccinated against COVID-19 and intended to have their children vaccinated, respectively. However, only 49.6% of children responded that they would get COVID-19 vaccination. In the multivariate analysis, high confidence in the safety of COVID-19 vaccines (adjusted odds ratio [AOR], 4.87; 95% confidence interval [CI], 1.32–24.12), parents' willingness to vaccinate themselves (AOR, 19.42; 95% CI, 6.85–64.00), and awareness of the need to vaccinate children against COVID-19 (AOR, 13.15; 95% CI, 4.77–41.27) were associated with positive factors intention to vaccinate their children.
Conclusion
This study provides insight into how parents think about the COVID-19 vaccine for their children in South Korea. Our findings could be referenced in establishing a policy for childhood COVID-19 vaccination in the future.

Coronavirus disease 2019 (COVID-19) is generally milder in children than in adults, and a substantial proportion of children with the disease have asymptomatic infections.Remdesivir is recommended for severe COVID-19. To date, there are little data on the outcomes of remdesivir treatment in children. We report a case of severe COVID-19 in a previously healthy but obese (body mass index, 27.6; 99.8 th percentile of the age) 9-year-old boy treated with remdesivir and dexamethasone. The patient had pneumonia at the time of diagnosis and required supplemental oxygen due to hypoxia one day after diagnosis. The patient developed respiratory distress as his pneumonia progressed rapidly. Therefore, remdesivir with dexamethasone therapy was initiated on hospital day 2. Supplemental oxygen was gradually weaned on hospital day 6 and stopped on hospital day 9. Significant improvement in pneumonic consolidations on chest X-ray was noted on hospital day 8. The patient was discharged on hospital day 21. We did not observe any adverse effects of remdesivir therapy and successfully treated a 9-year-old child with severe COVID-19.

Purpose:
To report a case of extensive syphilitic punctate inner retinitis (SPIR) triggering bilateral macular ischemia after intravitreal triamcinolone injections, and the multimodal retinal imaging findings.Case summary: A 69-year-old male patient with nonproliferative diabetic retinopathy was transferred to our hospital because of bilateral visual deterioration (to counting fingers) after the first intravitreal triamcinolone injection. Fundus examination revealed numerous yellow punctate precipitates in the superficial retinae, retinal arteriolitis, and vitritis. The punctate lesions and surrounding retinal regions showed decreased vascular density on optical coherence tomography angiography, and focal hypofluorescence on fluorescein angiography. The patient was positive for all of the Venereal Disease Research Laboratory test, the fluorescent treponemal antibody-absorption test, and Treponema pallidum hemagglutination; we diagnosed bilateral SPIR. After treatment with aqueous crystalline penicillin solutions (24 million units per day for 14 days), the punctate lesions reduced but arteriolitis progressed to obliterative vasculitis. After 6 months, the bilateral SPIR and vitritis resolved, and the bilateral visual acuity improved to 20/100. However, inner retinal and macular ischemia persisted because of capillary nonperfusion attributable to obliterative vasculitis.
Conclusions
Extensive SPIR can develop after an initial intravitreal steroid injection; the inner retinal ischemia and visual loss may persist after treatment because obliterative vasculitis develops. Therefore, patients scheduled for intravitreal steroid injections should be screened for syphilis infection.

Purpose:
To evaluate the clinical outcomes and prognostic factors of double-dose aflibercept in patients with refractory neovascular age-related macular degeneration (nAMD).
Methods:
We reviewed the medical records of nAMD patients treated with a double dose of aflibercept (4 mg/0.1 mL) due to an inadequate response to standard 8-weekly intravitreal injections of 2 mg/0.05 mL aflibercept. The assessment at week 8 after treatment included changes in subretinal/intraretinal fluid (SRF/IRF) and best-corrected visual acuity, with patients showing absence or reduction in SRF/IRF classified as the response group. Baseline factors influencing clinical outcomes were analyzed, including central macular thickness (CMT), central choroidal thickness (CCT), size of choroidal neovascularization (CNV), CNV subtype, and maximum height of SRF and IRF.
Results:
The study included 95 eyes of 95 subjects, with 61 eyes (64.2%) categorized as the response group following double-dose treatment. Responders exhibited thicker CCT (290.4 μm vs. 194.0 μm, p < 0.001), thinner CMT (251.2 μm vs 311.1 μm, p = 0.018), smaller CNV area (2.718 mm2 vs. 3.964 mm2, p = 0.034), and a higher prevalence of type 1 CNV (85.2% vs. 58.8%, p = 0.011) compared to the non-response group. Multivariate binary logistic regression analysis identified thicker CCT (p < 0.001, r = 1.016), thinner CMT (p = 0.014, r = 0.988), smaller CNV area (p = 0.015, r = 0.662), and type 1 CNV (p = 0.001, r = 0.061) as factors associated with better anatomical outcomes.
Conclusions
Double-dose aflibercept was effective in 64% of patients with refractory nAMD, suggesting it may be considered for those with small CNV areas, thinner CMT, and thicker CCT.

Journal of the Korean Ophthalmological Society 2024;65(5):320-327
Purpose:
To assess the impact of toxoplasma immunoglobulin G (IgG) titers on the diagnosis of active ocular toxoplasmosis.
Methods:
We retrospectively analyzed the medical records of patients tested for toxoplasma IgG at our uveitis clinic. Active ocular toxoplasmosis was clinically diagnosed based on wide-angle fundus photography and disease progression. Patients with IgG titers ≥ 30 IU/mL were classified as seropositive-high titer, those with IgG titers of 1.6-30 IU/mL as seropositive-low titer, and the remaining patients as seronegative. We compared the proportion of active ocular toxoplasmosis among these groups. Additionally, we evaluated the sensitivity and specificity of each titer and attempted to determine an ideal reference titer for toxoplasma IgG in diagnosing active ocular toxoplasmosis.
Results:
Out of 824 patients, 86 (10.4%), 88 (10.7%), and 650 (78.9%) were categorized as seropositive-high titer, seropositivelow titer, and seronegative, respectively. Among these patients, 34 in the seropositive-high titer group and 2 in the seropositive- low titer group were clinically diagnosed with active ocular toxoplasmosis. The false-positive rate was significantly different between the groups, being 60.5% in the seropositive-high titer group and 97.7% in the seropositive-low titer group (p < 0.001). The receiver operating characteristic curve indicated that 37.70 IU/mL could be an ideal reference titer for diagnosing ocular toxoplasmosis.
Conclusions
The false-positive rate was notably lower (60.5%) in patients with IgG titers ≥ 30 IU/mL compared to those with titers of 1.6-30 IU/mL (97.7%). Therefore, not only the presence of IgG but also the level of titer appears to be important in diagnosing ocular toxoplasmosis.
