RESUMEN
BACKGROUND: Cholesterol crystal embolization (CCE) is a multisystemic and fatal disease with multiple clinical manifestations; however, there are few cases of idiopathic CCE. Here we report a patient with idiopathic CCE accompanied by atheroembolic renal disease and blue toes who had a relatively good prognosis in the short-term due to early treatment with corticosteroids and statins. CASE SUMMARY: A 76-year-old man complained of coldness, numbness and purple color change in his left foot for 7 d. He had a feeling of fatigue, constipation, foamy urine, poor appetite and sleep. He had a lacunar infarction for 5 years and hypertension for 9 mo. Laboratory results showed elevated eosinophils, cholesterol, uric acid, serum creatinine, urea and 24 h urine analysis revealed proteinuria. A renal biopsy revealed atheroembolic renal disease. Taken together, these findings strongly supported the diagnosis of idiopathic CCE and atheroembolic renal disease. CONCLUSION: Atheroembolic renal disease and blue toes syndrome can be caused by idiopathic CCE, and early treatment with corticosteroids is effective but requires further investigation.
RESUMEN
OBJECTIVE: To observe the associations between regional peripheral refraction and myopia development in young Chinese people. METHODS: Two hundred and forty-one young adult subjects (21 emmetropes, 88 low myopes, 94 moderate myopes, and 38 high myopes) aged 18-28 years were included, and only the right eyes were tested. Eye biometrics were measured before pupil dilation using the Lenstar. Relative peripheral refractive errors (RPRE) were measured after pupil dilation using multispectral refractive topography (MRT), at nine retinal eccentricities: 0-5, 5-10, 10-15, 15-20, 20-25, 25-30, 30-35, 35-40, and 40-45 degrees. RESULTS: In this study, RPRE increased with eccentricity, and it shows a growing trend with the increase of the degree of myopia among emmetropia, low myopia and moderate myopia groups, and RPRE varied with myopia severity at eccentricities between 20 and 35 degrees only. In addition, axial length (AL) and RPRE were positively correlated between 20 and 45 degrees, and AL was an independent risk factor for RPRE between 20 and 35 degrees. CONCLUSION: These findings indicate that the eccentricities between 20 and 35 degrees RPRE may be closely related to refractive development and eye growth in young Chinese people.
RESUMEN
BACKGROUND: Globally, although the jellyfish population has increased in recent years, ocular jellyfish stings remain an uncommon ophthalmic emergency, and have been rarely reported. According to a few previous reports, ocular jellyfish stings may cause anterior segment disorders, and most of these injuries were self-limited and spontaneously resolved within 24 to 48 h. CASE SUMMARY: A brother and sister both presented with severe fundus complications several years after ocular jellyfish stings and both had prolonged blurred vision. To our knowledge, such fundus lesions induced by jellyfish stings have not been reported previously. CONCLUSION: The fundus status of patients following ocular jellyfish stings should be carefully monitored in cases of irreversible ocular damage.
RESUMEN
BACKGROUND: Cutaneous epithelioid angiomatous nodules (CEAN) are rare, benign, vascular lesions characterized by benign proliferation of endothelial cells with prominent epithelioid features, which can be easily confused with benign and malignant vascular tumors. However, the etiology of CEAN remains unclear, and no association with infection, trauma, or immunosuppression has been described. This case study indicated that CEAN is closely related to the patient's impaired immune status and may be induced by cyclosporine. CASE SUMMARY: A 19-year-old boy with nephrotic syndrome (NS) developed large CEAN on the left foot during treatment for NS. He had repeated relapses of edema in the past 6 years and different types of immunosuppressants were administered including methylprednisolone, mycophenolate mofetil, tacrolimus and cyclosporine; the dosages of these drugs were frequently adjusted. The patient had been receiving cyclosporine and methylprednisolone for 7 mo before he developed CEAN. Cyclosporine was discontinued due to its side effects on skin. After cessation of cyclosporine and 16 mo follow-up, the nodules gradually disappeared without any other treatment for the CEAN. CONCLUSION: Impaired immune status is proposed to be a risk factor for CEAN, which may be induced by cyclosporine.
