    The authors studied the clinical features of the infant with cerebral ischemia, hepatosplenomegaly and combined forms of perinatal pathology. Found the relationship between the pathological conditions of the early neonatal period and neonatal infections. In a survey of 224 infants participated maternity hospital № 2 in Krasnoyarsk. PCR method was studied serum of these children for the detection of DNA Chlamydia trachomatis, Mycoplasma genitalium, Ureaplasma sp., Cytomegalovirus  and Herpes simplex type 1 and 2. Proved the highest rate of infection of children with combined perinatal diseases (48.6%) compared with children with cerebral ischemia (33.3%) and hepatosplenomegaly (36.8%). In this case, in healthy children of the control group data pathogens were detected.DOI: http://dx.doi.org/10.12731/2218-7405-2013-5-42Авторами изучены клинические особенности состояний новорожденных с церебральной ишемией, гепатоспленомегалией и сочетанными формами перинатальной патологии.  Найдена взаимосвязь между этими патологическими состояниями раннего неонатального периода и инфицированностью новорожденных возбудителями внутриутробных инфекций.  В обследовании приняли участие 224 новорожденных родильного  дома №2 города Красноярска.

    PURPOSE: To determine the size at which choroidal melanomas can metastasize and to report the characteristics of small fatal choroidal melanomas (SFCM). DESIGN: Retrospective case series. METHODS: Ten ocular oncology services submitted 45 patients with a choroidal melanoma 3 mm or less in thickness and 9 mm or less in largest basal diameter (LBD), when treated, who developed metastases. RESULTS: Median tumor thickness was 2.4 mm (range, 1.0-3.0 mm) and LBD 7.3 mm (range, 3.0-9.0 mm). Of 14 (31%) tumors that were first observed, 12 grew a median of 0.5 mm (range, 0.1-1.2 mm) in thickness and 1.0 mm (range, 0-3.0 mm) in LBD within a median of 7 months; 3 were initially smaller than 3 mm in LBD. Number of risk factors for growth and metastasis was 0 for 4% of the tumors; 60% were over 2 mm in thickness, 63% had subretinal fluid, 84% caused symptoms, 57% had orange pigment, and 92% were within 3 mm of the disc. Local recurrence occurred in 8 of 31 eyes (26%) treated conservatively. Median metastasis-free survival was 4.5 years (range, 0.8-15.7 years). Kaplan-Meier estimate of metastasis developing was 15% (95% confidence interval [CI], 7-26), 51% (95% CI, 36-64) and 85% (95% CI, 71-92) by 2, 5, and 10 years, respectively. By the time of analysis, 37 patients had died of metastasis after a median of 7 months. CONCLUSIONS: Choroidal melanomas less than 3.0 mm in LBD are highly unlikely to metastasize. Risk factors of an SFCM are similar to those for all choroidal melanomas of similar size. (C) 2019 The Author(s). Published by Elsevier Inc.Peer reviewe

    The Pediatric and Young Adult Choroidal and Ciliary Body Melanoma Genetic Study, A Survey by the European Ophthalmic Oncology Group

    PURPOSE:To explore the genetic background of choroidal and ciliary body melanoma among children and young adults, with special focus on BAP1 germline variants in this age group. METHODS:Patients under the age of 25 and with confirmed choroidal or ciliary body melanoma were included in this retrospective, multicenter observational study. Nuclear BAP1 immunopositivity was used to evaluate the presence of functional BAP1 in the tumor. Next-generation sequencing using Ion Torrent platform was used to determine pathogenic variants of BAP1, EIF1AX, SF3B1, GNAQ and GNA11 and chromosome 3 status in the tumor or in DNA extracted from blood or saliva. Survival was analyzed using Kaplan-Meier estimates. RESULTS:The mean age at diagnosis was 17 years (range 5.0–24.8). A germline BAP1 pathogenic variant was identified in an 18-year-old patient, and a somatic variant, based mainly on immunohistochemistry, in 13 (42%) of 31 available specimens. One tumor had a somatic SF3B1 pathogenic variant. Disomy 3 and the absence of a BAP1 pathogenic variant in the tumor predicted the longest metastasis-free survival. Males showed longer metastasis-free survival than females (P = 0.018). CONCLUSIONS:We did not find a stronger-than-average BAP1 germline predisposition for choroidal and ciliary body melanoma among children and young adults compared to adults. Males had a more favorable survival and disomy 3, and the absence of a BAP1 mutation in the tumor tissue predicted the most favorable metastasis-free survival. A BAP1 germline pathogenic variant was identified in one patient (1%), and a somatic variant based mainly on immunohistochemistry in 13 (42%).</p

    Purpose: To collect comprehensive data on choroidal and ciliary body melanoma (CCBM) in children and to validate hypotheses regarding pediatric CCBM: children younger than 18 years, males, and those without ciliary body involvement (CBI) have more favorable survival prognosis than young adults 18 to 24 years of age, females, and those with CBI. Design: Retrospective, multicenter observational study. Participants: Two hundred ninety-nine patients from 24 ocular oncology centers, of whom 114 were children (median age, 15.1 years; range, 2.7-17.9 years) and 185 were young adults. Methods: Data were entered through a secure website and were reviewed centrally. Survival was analyzed using Kaplan-Meier analysis and Cox proportional hazards regression. Main Outcome Measures: Proportion of females, tumor-node-metastasis (TNM) stage, cell type, and melanoma-related mortality. Results: Cumulative frequency of having CCBM diagnosed increased steadily by 0.8% per year of age between 5 and 10 years of age and, after a 6-year transition period, by 8.8% per year from age 17 years onward. Of children and young adults, 57% and 63% were female, respectively, which exceeded the expected 51% among young adults. Cell type, known for 35% of tumors, and TNM stage (I in 22% and 21%, II in 49% and 52%, III in 30% and 28%, respectively) were comparable for children and young adults. Melanoma-related survival was 97% and 90% at 5 years and 92% and 80% at 10 years for children compared with young adults, respectively (P = 0.013). Males tended to have a more favorable survival than females among children (100% vs. 85% at 10 years; P = 0.058). Increasing TNM stage was associated with poorer survival (stages I, II, and III: 100% vs. 86% vs. 76%, respectively; P = 0.0011). By multivariate analysis, being a young adult (adjusted hazard rate [HR], 2.57), a higher TNM stage (HR, 2.88 and 8.38 for stages II and III, respectively), and female gender (HR, 2.38) independently predicted less favorable survival. Ciliary body involvement and cell type were not associated with survival. Conclusions: This study confirms that children with CCBM have a more favorable survival than young adults 18 to 25 years of age, adjusting for TNM stage and gender. The association between gender and survival varies between age groups. (C) 2016 by the American Academy of Ophthalmology.Peer reviewe

    No full text
    Purpose: To assess the angiographic and optical coherence tomography angiography (OCTA) features as well as the natural course of the choroidal neovascularization (CNV) associated with choroidal naevi. Setting/venue: Ocular Oncology Service, Department of Ophthalmology, Poznan University of Medical Sciences. Material and methods: Retrospective chart analysis of the patients who presented to the Ocular Oncology Service in Poznan, Poland between 2011–2021 with the diagnosis of suspicious choroidal naevus. In all patients full ophthalmic examination and multimodal imaging, including fundus photography, autofluorescence, B-ultrasound, optical coherence tomography (OCT), OCT angiography (OCTA) and fluorescein angiography (FAF), were performed. Results: There were 9 lesions in 9 patients, 9 women aged 14–79 years (mean age: 58.2 years). All the lesions were located in the posterior pole and most of them were pigmented (88.9%). CNVs associated with choroidal naevi were type I in 66.7% and type II in 33.3% of cases. 5 patients required treatment: anti-VEGF injection (alone or with transpupillary thermotherapy) was administered. The median follow-up was 24 months (range: 2–145). In two of all treated patients (40%), we observed BCVA gain (2–4 lines), in one patient (20%) it remained stable and in two (40%) it deteriorated. The final visual acuity was below 0.1 only in 1 patient. During the period of observation none of the lesions progressed to uveal melanoma. Conclusions: CNV associated with choroidal naevus could be the reason for subretinal fluid (SRF) leakage and visual loss. The response to anti-VEGF treatment is satisfactory in the majority of patients. Choroidal naevi with accompanying CNV have none or very low malignant transformation potential

    No full text
    Purpose : The aim of this study was to report on results of uveal melanoma treatment with ruthenium-106 ( 106 Ru) brachytherapy with long-term follow-up, in terms of local tumor control, eye retention rate, radiation retinopathy, and patients’ survival. Material and methods : Medical records of patients treated with ruthenium plaque due to uveal melanoma at the Department of Ophthalmology, Poznan University of Medical Sciences, Poland, between 1994 and 2014 were retrospectively reviewed. Results : We identified 126 patients: 53 men, 73 women, mean age 60.04 years (range, 21-89). The largest basal diameter ranged from 4.04 mm to 18.9 mm (median, 10.67 mm), tumor height was 1.9 mm to 7.42 mm (median, 4.8 mm). Median scleral radiation dose was 570 Gy (range, 235-1,500 Gy), median apical dose 100 Gy (range, 60-129 Gy). Median follow-up was 66.5 months (range, 2-261 months). We noted a total of 19 (15%) recurrences. The actuarial rate of recurrence was 9.5% at 3 years, and 13.5% at 5 years postoperatively. Nine (7%) eye globes were lost, median time to enucleation was 5 years. The eye retention rate at 5 years was 92.7% and 81% at 10 years. Forty-three (34%) patients died before the end of the study, 24 (19%) of them due to metastatic disease. Metastatic death was related to: tumor size and TNM stage at presentation (p = 0.002 vs. p = 0.0006, respectively) but not to age, gender, and plaque dosimetry. Conclusions : 106 Ru brachytherapy is an effective, globe sparing treatment that provides good tumor control and a high rate of survival. However, some ocular complications tend to appear late post-treatment, and therefore long-term follow-up is advised
