Autorska književno-likovna izdanja Vlade Kristla nastajala su usporedno s njegovim slikarskim i filmskim radom. Obuhvaćaju širok raspon otisnutih publikacija, od knjiga proze i poezije, preko tzv. ...knjiga umjetnika do otisnutih mapa; nizu se može pribrojiti i dio odaslane korespondencije kao forme koju je Kristl također koristio kao umjetnički medij. U svim tim vrstama djela prate se isti poetički postupci, teme i topika kao i u ostalim segmentima njegova opusa. Karakterizira ih i specifično oblikovanje slike i teksta, općenito eksperimentiranje s formom knjige te prožimanje literarnog i likovnog izraza. Prije preseljenja u Njemačku 1963. piše i objavljuje uglavnom na hrvatskome, a nakon toga sva su izdanja napisana i objavljena na njemačkom jeziku.
In the artistic oeuvre of Vlado Kristl (Zagreb, 1923 – Munich, 2004), a respected film author and painter, the literary segment also holds a significant place. Literary and art publications were created simultaneously with his painting and film work, encompassing a wide range of printed materials, from prose and poetry books to artists’ books, portfolios, letters, and faxed messages — a form that Kristl also used as an art medium. Kristl personally designed, illustrated, and most often published these authorial editions by himself. He predominantly designed them with minimal economic resources but exceptionally innovatively, using various typographies, seals, his own handwriting, illustrations, and photographs. The bound works, with a distinctly creative approach to content and design, belong to artistic production closely related to both film and painting. They are propelled by the same poetics marked by processuality and experimentation, with timeless themes and topics, such as the role of the artist, freedom, repression, war and resistance, and the relationship towards authority. Everything he filmed, painted, drew, or wrote was connected by the same fundamental need for shaping and demonstrative expression of a kind of artistic worldview, a value system that encompassed his understanding of art as well as his attitude towards society and the political order. Just as he often copied his paintings and changed scenarios or montages, he also revised and modified his poetic and prose texts in his books, using those already published as a kind of ready-made material. In this way, he transformed his existing works into new ones, questioning their meanings and giving the entire oeuvre a character of an unfinished work to which he constantly returned, seeking to redefine it. Like in all other media, Kristl approached books and their conventions provocatively and destructively: playing with language and its trans - parency, transcending the usual relationship between textual and visual contents, as well as the format and functional parts of editions, using existing works, fragmenting them, and leaving the final sequence of the text to chance. With the exception of the first two poetry collections written in Croatian, all other books were in German, a language that was not Kristl’s native but one he knew well even before coming to Germany. Kristl’s authorial editions, as a special form of artistic expression in the form of a book, are carefully thoughtout projects that directly connect literary achievements with reproductions of drawings and paintings, treating them as material that is secondarily processed, collaged, and otherwise shaped, creating a new type of artefact. As such, they represent a multimedia form of artistic expression that conveys the message both verbally and visually, uniting both languages into a specific narrative and visual form.
Pathogenic variants in DNA-damage regulated autophagy modulator 2 gene (DRAM2) cause a rare autosomal recessive retinal dystrophy and its disease course is not well understood. We present two ...Slovenian patients harboring a novel DRAM2 variant and a detailed review of all 23 other patients described to date. Whole exome and whole genome sequencing were performed in the two patients, and both underwent ophthalmological examination with a 2-year follow-up. PubMed was searched for papers with clinical descriptions of DRAM2 retinopathy. Patient 1 was homozygous for a novel variant, p.Met1?, and presented with the acute onset of photopsia and retina-wide retinopathy at the age of 35 years. The patient was first thought to have an autoimmune retinopathy and was treated with mycophenolate mofetil, which provided some symptomatic relief. Patient 2 was compound heterozygous for p.Met1? and p.Leu246Pro and presented with late-onset maculopathy at the age of 59 years. On review, patients with DRAM2 retinopathy usually present in the third decade with central visual loss, outer retinal layer loss on optical coherence tomography and a hyperautofluorescent ring on fundus autofluorescence. Either cone–rod or rod–cone dystrophy phenotype is observed on electroretinography, reflecting the importance of DRAM2 in both photoreceptor types. Non-null variants can result in milder disease.
The pathogenic variant p.G90D in RHO is believed to be responsible for a spectrum of phenotypes, including congenital stationary blindness (for the purpose of this study termed night blindness ...without degeneration; NBWD), Sector RP, Pericentral RP, and Classic RP. We present a correlation between the serum concentration of vitamin A and disease severity in patients with this variant. This prospective study involved 30 patients from 7 families (17 male; median age 46 years, range 8−73). Full ophthalmological examination including visual acuity, Goldmann perimetry, slit-lamp exam, optical coherence tomography, fundus autofluorescence, and electrophysiology was performed to determine the presenting phenotype. The serum concentration of vitamin A was determined from a fasting blood sample taken on the day of the exam, where it was found that 23.3% (7/30) of patients had NBWD, 13.3% (4/30) had Sector RP, 3.3% (1/30) had Pericentral RP, and 60% (18/30) had Classic RP. Multiple logistic regression revealed a significantly higher probability of having a milder phenotype (NBWD or Sector RP) in association with younger age (p < 0.05) and a higher concentration of vitamin A (p < 0.05). We hypothesize that vitamin A in its 11-cis-retinal form plays a role in stabilizing the constitutively active p.G90D rhodopsin and its supplementation could be a potential treatment strategy for p.G90D RHO patients.
(1) Background: The purpose of this study was to evaluate the thickness of retinal layers in Leber hereditary optic neuropathy (LHON) in the atrophic stage compared with presumably inherited ...bilateral optic neuropathy of unknown cause with the aim of seeing if any LHON-specific patterns exist. (2) Methods: 14 patients (24 eyes) with genetically confirmed LHON (LHON group) were compared with 13 patients (23 eyes) with negative genetic testing results (mtDNA + WES) and without identified etiology of bilateral optic atrophy (nonLHON group). Segmentation analysis of retinal layers in the macula and peripapillary RNFL (pRNFL) measurements was performed using Heidelberg Engineering Spectralis SD-OCT. (3) Results: In the LHON group, the thickness of ganglion cell complex (GCC) (retinal nerve fiber layer (RNFL)—ganglion cell layer (GCL)—inner plexiform layer (IPL)) in the central ETDRS (Early Treatment Diabetic Retinopathy Study) circle was significantly higher than in the nonLHON group (p < 0.001). In all other ETDRS fields, GCC was thinner in the LHON group. The peripapillary RNFL (pRNFL) was significantly thinner in the LHON group in the temporal superior region (p = 0.001). Longitudinal analysis of our cohort during the follow-up time showed a tendency of thickening of the RNFL, GCL, and IPL in the LHON group in the central circle, as well as a small recovery of the pRNFL in the temporal region, which corresponds to the observed central macular thickening. (4) Conclusions: In LHON, the retinal ganglion cell complex thickness (RNFL-GCL-IPL) appears to be relatively preserved in the central ETDRS circle compared to nonLHON optic neuropathies in the chronic phase. Our findings may represent novel biomarkers as well as a structural basis for possible recovery in some patients with LHON.
Background
We present the disease course and long-term follow-up of two patients who were phenotypically diagnosed with atypical Leber Hereditary Optic Neuropathy (LHON) 14 and 12 years ago, ...respectively, whereby whole exome sequencing revealed recently described recessive DNAJC30:c.152G>A 152 A>G (p.Tyr51Cys) homozygous pathogenic variant with significant spontaneous visual acuity recovery in one.
Case presentation
Two presented unrelated males with atypical LHON with sequential visual acuity (VA) loss were followed for many years. Both patients had negative family history. At the presentation at ages 17 (Case 1) and 18 years (Case 2), both had reduced visual acuity (Snellen): (Case 1) right eye (RE):CF 3m, left eye (LE):0.6, (Case 2) RE:0.2, LE:0.15; and color vision (Ishihara): (Case 1) 1/15 and 13/15; (Case 2) 2/15 and 3/15. Both had hyperemic optic disks (PNO) and central scotoma in their visual fields. Electrophysiology in the acute phase showed reduced and delayed visually evoked potentials (VEP) P100 in both patients, with reduced N95 amplitude in Case 2, and initially normal N95 amplitude in Case 1. Fluorescein angiography showed no early leakage with some late pooling at optic disks. Extensive clinical workout, including brain magnetic resonance imaging (MRI), aquaporin 4 (Aq4), and anti-myelin oligodendrocyte protein (anti-MOG) antibodies, was negative. Intravenous corticosteroids did not improve vision. Both experienced further deterioration several months after the onset accompanied by thinning of the peripapillary retinal nerve fiber layer (RNFL). Genetic testing for typical LHON pathogenic variants and whole mitochondrial DNA (mtDNA) sequencing was negative. 1 year after the onset, modest VA improvement began in Case 2 and continued over the next 3 years. VA improved bilaterally to 0.7, color vision 15/15, and islands of vision appeared within the visual field scotoma. VEP P100 peak time shortened, and amplitude increased, despite further RNFL thinning on optical coherent tomography (OCT). The patient's visual function remained stable during the entire 12-year follow-up period. Case 1 experienced modest VA improvement to 0.1 with some improvement in the visual field seven years after the disease onset, remaining stable during the entire 14-year follow-up period. VEP P100 wave remained undetectable.
Conclusions
Presented are two autosomal recessive LHON (arLHON, OMIM:
619382
) cases with the same DNAJC30:c.152G>A pathogenic variant and different degrees of spontaneous visual recovery despite progressive RNFL thinning during a long-term follow-up. This mutation should be screened in every atypical LHON patient.
