RESUMO
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.
RESUMO
Coronavirus disease 2019 (COVID-19) vaccination is necessary to prevent infection, morbidity, and mortality. In addition to the usual post-inoculation hypersensitivity reactions including headaches, muscle and joint pain, and fever, especially after the second shot, the mRNA vaccine has risk of inflammation in the heart and heart lining of some recipients, mostly younger people. And the adenovirus vector vaccine can induce rare immune thrombocytopenia. Vaccination should be encouraged according to the information about the effectiveness and safety in individual situation.
RESUMO
Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) may be observed in various types of cancer, but is mainly seen in small-cell carcinoma. It can also be caused by several chemotherapeutic agents. However, it is a very rare phenomenon in esophageal cancer or its treatment. We report here on a case of SIADH related to esophageal cancer treatment. A 55-year-old man received chemoradiotherapy (CRT) for esophageal cancer. After receiving CRT for 5 days, he complained of nausea, dizziness, and general weakness, and his sodium level had dropped to 107 mEq/L. His volume status was clinically euvolemic and there were no edema or pigmentation. After hypertonic saline infusion, the sodium level increased and the symptoms improved. There have been several reports of SIADH associated with malignancies or chemotherapy agents. However, to the best of our knowledge, this is the first Korean case of SIADH associated with esophageal cancer that occurred after cisplatin treatment.
