- Spontaneous bleeds are a leading cause of death in the pediatric JAG1-related liver disease Alagille syndrome (ALGS). We asked whether there are sex differences in bleeding events in patients, whether Jag1(Ndr/Ndr) mice display bleeds or vascular defects, and whether discovered vascular pathology can be confirmed in patients non-invasively. We performed a systematic review of patients with ALGS and vascular events following PRISMA guidelines, in the context of patient sex, and found significantly more girls than boys reported with spontaneous intracranial hemorrhage. We investigated vascular development, homeostasis, and bleeding in Jag1(Ndr/Ndr) mice, using retina as a model. Jag1(Ndr/Ndr) mice displayed sporadic brain bleeds, a thin skull, tortuous blood vessels, sparse arterial smooth muscle cell coverage in multiple organs, which could be aggravated by hypertension, and sex-specific venous defects. Importantly, we demonstrated that retinographs from patients display similar characteristics with significantly increased vascular tortuosity. In conclusion, there are clinically important sex differences in vascular disease in ALGS, and retinography allows non-invasive vascular analysis in patients. Finally, Jag1(Ndr/Ndr) mice represent a new model for vascular compromise in ALGS.

Synergonomi och ögonbesvär hos personal på ögonsjukhus.
- 2012
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Ögonläkare, ögonsjuksköterskor, optiker och annan personal på ögonsjukhus arbetar ofta med synkrävande arbetsuppgifter i dämpad belysning eller helt utan allmänbelysning. Inför den planerade byggnationen av ett nytt ögonsjukhus i Stockholm ca år 2018 gjordes en enkätstudie för att kartlägga ögonbesvär och trötthet hos personalen på S:t Eriks Ögonsjukhus. Studien som är ett multidisciplinärt samarbetsprojekt mellan S:t Erik, Karolinska Institutet och Kungliga Tekniska Högskolan, syftar till att optimera belysning, dagsljusinsläpp och ljusmiljö vid det nya ögonsjukhuset.Totalt 265 anställda på S:t Eriks Ögonsjukhus samt 60 röntgenläkare och 45 barnläkare, varav de senare två utgjorde jämförelsegrupper, inviterades till studien. Enkäten som distribuerades baserades på synergonomienkäter av Knave och Hemphälä och bestod av 31 validerade frågor om subjektiva ögonbesvär, nuvarande belysning, tillgång till dagsljus och välbefinnande. Ögonbesvären räknades om till ett gruppmedelvärde (ögonbesvärsindex) med avseende på svårighetsgrad och frekvens. Studien är godkänd av Etikprövningsnämnden. Nittiosex av 265 (33%) anställda på S:t Eriks Ögonsjukhus hade t o m juni 2012 besvarat enkäten tillsammans med 23 röntgenläkare (38%) och 14 barnläkare (31%). Ögonbesvär som torrhets- och gruskänsla var vanligt förekommande hos alla yrkesgrupper på ögonsjukhuset och generellt vanligare hos kvinnor. Då samtliga grupper jämfördes med avseende på ögonbesvärsindex var skillnaden mellan män och kvinnor statistiskt säkerställd (p<0,05). Röntgenläkarna rapporterade högst ögonbesvärsindex och barnläkarna lägst, skillnaden mellan dessa yrkesgrupper var signifikant (p<0,05). Ögonpersonal och röntgenläkare som rapporterade att de ofta arbetade i mörker, associerade detta med ökad trötthet i högre grad än med barnläkarna (p<0,05).Ögonbesvär var vanliga hos ögonpersonalen inkluderade i studien. Den grupp som arbetade mest i mörker hade mer ögonbesvär än den grupp som arbetade minst i mörker. Kvinnor hade mer ögonbesvär än män. Arbete i mörker ökade den subjektiva känslan av trötthet . Optimala ljusförhållanden och bra synergonomi bör ges hög prioritet vid planering av ett nytt ögonsjukhus.

Tidskriftsartikel (refereegranskat)abstract
- To estimate the burden of disease due to congenital toxoplasmosis in Sweden the incidence of primary infections during pregnancy and birth prevalence of congenital toxoplasmosis in 40978 children born in two regions in Sweden was determined. Women possibly infected during pregnancy were identi®ed based on: 1, detection of speci®c IgG based on neonatal screening of the phenylketonuria (PKU) card blood spot followed by retrospective testing of stored prenatal samples to detect women who acquired infection during pregnancy and follow up of their children to 12 months; 2, detection of speci®c IgM on the PKU blood spot. The birth prevalence of congenital toxoplasmosis was 0±73}10000 (95% CI 0±15±2±14) (3}40978). The incidence of primary infection during pregnancy was 5±1}10000 (95% CI 2±6±8±9) susceptible pregnant women. The seroprevalence in the southern part was 25±7% and in the Stockholm area 14±0%. The incidence of infection during pregnancy was low, as the birth prevalence of congenital toxoplasmosis. Neonatal screening warrants consideration in view of the low cost and feasibility.

- Non-graft-versus-host disease (GVHD) ocular complications are generally uncommon after hematopoietic cell transplantation (HCT) but can cause prolonged morbidity affecting activities of daily living and quality of life. Here we provide an expert review of non-GVHD ocular complications in a collaboration between transplantation physicians and ophthalmologists through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation. Complications discussed in this review include cataracts, glaucoma, ocular infections, ocular involvement with malignancy, ischemic microvascular retinopathy, central retinal vein occlusion, retinal hemorrhage, retinal detachment and ocular toxicities associated with medications. We summarize the incidence, risk factors, screening, prevention, and treatment of individual complications and generate evidence-based recommendations. Baseline ocular evaluation before HCT should be considered in all patients who undergo HCT. Follow-up evaluations should be considered according to clinical signs and symptoms and risk factors. Better preventive strategies and treatments remain to be investigated for individual ocular complications after HCT. Both transplantation physicians and ophthalmologists should be knowledgeable about nonGVHD ocular complications and provide comprehensive collaborative team care.

- AimsTo determine the ophthalmological outcome at 6.5 years of age in children treated for retinopathy of prematurity (ROP), and registered in the national Swedish National Register for ROP register. MethodsData on ROP, treatment and ophthalmological outcome were retrieved from the register. Visual acuity (VA), refractive errors and strabismus, together with visual impairment (VI) and any significant eye problem, defined as VA >0.5 logarithm of the minimal angle of resolution (logMAR) and/or strabismus and/or any refractive error were analysed. Risk factors such as sex, gestational age (GA), birth weight SD score, number of treatments and retreatments, postnatal age and postmenstrual age at first treatment were analysed. ResultsFollow-up data were available in 232 of 270 children born between 2007 and 2014 who had been treated for ROP. VI (VA >0.5 logMAR) was found in 32 (14%), strabismus in 82 (38%), refractive errors in 114 (52%) and significant eye problem in 143 (65%) children. Retreatment was a risk factor for VI and refractive errors. Male sex and neonatal brain lesion were risk factors for strabismus. An additional week of GA at birth reduced the risk for refractive errors, strabismus and significant eye problems. ConclusionThe results of the present study revealed a high number of eye problems in children treated for ROP, emphasising the need for long-term follow-up. Retreatment of ROP was a risk factor for VI, and emphasises the importance of an accurate first treatment for the long-term ophthalmological outcome.

- BACKGROUND: In many western countries individuals will need to continue their professional careers beyond the current retirement age. This requires adaptation of the working conditions to compensate for age related visual changes. OBJECTIVE: The aim of this paper is to compile and structure knowledge concerning age related changes in visual and non-visual functions among older-age workers and to describe in what way these changes relate to light and work performance. METHOD: An overview of the literature was performed in PubMed and EMBASE concerning visual changes among elderly people, light, visual ergonomics and consequences at work. RESULTS: Visual conditions and lighting design have an impact on work performance in those over age 65 even if there are few studies available. Natural age related changes in the eyes or ocular diseases can result in reduced visual function and performance. Moreover, evidence of the importance of light and dark rhythms for circadian regulation is mounting; there are indications that the older-age population might need specific attention related to this issue. Finally, visual deteriorations might also, secondarily, induce strained postures and musculoskeletal symptoms, pain and injury. CONCLUSION: Age-related changes in the eyes and also ocular diseases among older-age people have an impact on well-being and work performance, and therefore call for reconsideration of their working conditions. Knowledge about how visual functions, light and ocular diseases is needed for work design and preventive actions.

- OBJECTIVE: To describe visual outcomes after penetrating keratoplasty and deep anterior lamellar keratoplasty in patients with mucopolysaccharidoses. METHODS: This is a retrospective review of keratoplasty in consecutive patients from Brazil, England, Finland, Germany, Portugal, Sweden and the USA. All patients had corneal clouding due to mucopolysaccharidoses. Preoperative and postoperative visual outcome and ocular comorbidities were identified. Success was arbitrarily defined as any improvement in visual acuity or best-corrected visual acuity better than logarithm of the minimum angle of resolution 0.30 (20/40). Statistical analysis included only data from first operated eyes in the 16 patients who underwent bilateral keratoplasty. RESULTS: Forty-eight eyes from 32 patients with mucopolysaccharidoses I, IV or VI are reported. Mean follow-up was 70 months (range: 5-186). Penetrating keratoplasty was performed in 45 eyes and deep anterior lamellar keratoplasty in 3 eyes. At last follow-up, a successful visual outcome for penetrating keratoplasty in first operated/only operated eyes was found in 63%. Rejection episodes occurred in 23% of grafts; however, a clear graft was recorded at last follow-up in 94%. Ocular pathway comorbidities were identified in 63% of eyes transplanted. CONCLUSIONS: Clear corneal grafts can be obtained for patients with corneal clouding due to mucopolysaccharidosis with improvement in visual acuity in the majority.
