Stargardts disease (also called Stargardts macular degeneration or Stargardts macular dystrophy) is a rare inherited eye condition which affects the central area of the retina called the macula. It is also sometimes called fundus flavimaculatus. It affects about 1 in 10,000 people. Stargardts disease is sometimes called a juvenile macular dystrophy since it tends to first
Doheny doctors treat patients with retinal disease daily; and we also work continuously with colleagues around the world to find ways to fight these diseases. I want to share a few insights about one of those important efforts -a study of Stargardts Disease called ProgStar, sponsored by the Foundation Fighting Blindness.. ProgStar uses data sets from all over the world to analyze images and eye exam results in a quest to understand the rate of progression of Stargardts disease and how it can best be thwarted or eliminated. The data allows us to evaluate, and to better understand, how quickly the retina is deteriorating and how that decline is affecting visual acuity.. I am happy to let you know the Doheny Image Reading Center is the reading center for all of the data collected in the ProgStar study. Our work at the DIRC is integral to this critical research, and the meaning is significant: with adequate data, the launch of studies to test and approve drugs to treat Stargardts is ...
As such, I feel absolutely fine. Its only while reading, I have to bring the book very close to my eyes. Even on the computer, I sit very close (8 or 9 inches from the screen). I also have problem recognizing people from a distance. Otherwise I drive regularly, but during night I find it to be problematic. But guess what, I am not 100% sure if I do have Stargardts Disease. When I was 18, I was told by a doctor that I had Stargardts Disease. What are the tests that I need to get done to confirm this, and how severe it is? Hoping that someone will help me out here..

WHO IS AT RISK?. Age-related Macular degeneration (AMD) is usually considered to be an older persons disease and often begins in an asymptomatic form sometime around the age 50. As you age, the chances of incurring AMD or beginning to see the visual symptoms, increase. 25% of those 65+ have AMD; and, by the time you are 75+ there is a 35% chance you will be affected. (There is also a rare juvenile form of AMD, called "Stargardts Disease".) A number of factors have been found to be related to AMD, including:. ...
immune Uncategorized Rabbit Polyclonal to Integrin beta1, Tariquidar Oligodendroglial tumors form a definite subgroup of gliomas, seen as a an improved response to treatment and long term overall survival. marks ICIV). Gliomas exhibiting oligodendroglial features consist of oligodendrogliomas (WHO quality II) and anaplastic oligodendrogliomas (WHO quality III) aswell as oligoastrocytomas (WHO quality II), anaplastic oligoastrocytomas (WHO quality III) and glioblastomas with an oligodendroglial component (GBMO, WHO quality IV) [1]. Oligodendroglial tumors take into account 15-20% of most gliomas [2,3]. The recognition from the genes targeted by full 1p/19q co-deletion, a quality of oligodendrogliomas, is a long-standing Tariquidar search. Combined lack of entire chromosome hands 1p and 19q may be the most frequently recognized hereditary imbalance in oligodendroglial tumors, happening in 60-90% of oligodendrogliomas and 30-50% of oligoastrocytomas while they may be rarely within GBMO [4-6].

N2 - The chromosome (chr) 1p deletion is a favorable biomarker in oligodendroglial tumors and is even more powerful a marker when combined with chr 19q loss. As a result, the 1p deletion is taken into account more and more in clinical trials and the management of patients. However, the laboratory technique implemented for detection of this biomarker has been a topic of debate. To illustrate the usefulness of evaluating multiple loci, we here report two anaplastic oligodendrogliomas that were investigated using fluorescent in situ hybridization (FISH) and bacterial artificial chromosome (BAC)-array-based comparative ...

The ZytoDot ® 2C SPEC 1p36/1q25 Probe is designed for the detection of 1p deletions by Chromogenic in situ Hybridization (CISH). Deletions affecting the short arm of chromosome 1 (1p) are frequently found in human gliomas and neuroblastomas, but also in breast, lung, endometrial, ovarian, and colorectal carcinomas. Loss of 1p is a strong prognostic factor in patients with neuroblastoma. Since loss of 1p reliably identifies patients at high risk in stages I, II, and IVS, which are otherwise clinically favorable, more aggressive therapy may be considered in these patients. Several studies showed correlation of combined allelic losses at 1p36 and 19q13 with oligodendroglioma histology and association with both chemotherapeutic response and survival in patients with anaplastic oligodendrogliomas. Hence, determination of 1p and 19q status may aid therapeutic decisions and predict outcome in patients with anaplastic oligodendrogliomas.

Stargardts disease (STGD) and Retinitis Pigmentosa (RP) are inherited retinal degenerations that may be affected, in opposite way, by diet. Dietary profile was assessed in 24 patients with STGD and in 56 patients with RP. We documented in only 6 out of 24 (25 %) STGD patients a daily intake of vitamin A within the recommended range while 14/24 (58.3 %) reported a high daily intake and 4/24 (16.7 %) showed a low daily intake. With regard to RP, 4/56 (7.1 %) reported to be within the recommended range, 37/56 (66.1 %) reported high daily intake and 15/56 (26.8 %) showed low daily intake of vitamin A. Interestingly, STGD patients with low vitamin A intake (|600 µg RAE/day) showed significantly better visual acuity with respect to those introducing higher intake of vitamin A. The present study suggests insuitable nutrient intakes among patients with STGD and RP, especially for daily intake of vitamin A. The results may be used to provide tailored nutritional interventions in these patients.
Anaplastic oligodendroglial tumors are rare neoplasms with no standard approach to treatment. We sought to determine patterns of treatment delivered over time and identify clinical correlates of specific strategies using an international retrospective cohort of 1013 patients diagnosed from 19812007. Prior to 1990, most patients received radiotherapy (RT) alone as initial postoperative treatment. After 1990, approximately 50 of patients received both RT and chemotherapy (CT) sequentially and/or concurrently. Treatment with RT alone became significantly less common (67 in 19801984 vs 5 in 20052007, P | .0001). CT alone was more frequently administered in later years (0 in 19801984 vs 38 in 20052007; P | .0001), especially in patients with 1p19q codeleted tumors (57 of codeleted vs 4 with no deletion in 20052007; P | .0001). Temozolomide replaced the combination of procarbazine, lomustine, and vincristine (PCV) among patients who received CT alone or with RT (87 vs 2 in 20052007). In the most recent time
Clinical management of grade III oligodendroglioma G Simonetti, P Gaviani, A Botturi, A Innocenti, E Lamperti, A Silvani Neurooncology Unit, Fondazione IRCCS Istituto Neurologico Carlo Besta, Milan, Italy Abstract: Oligodendrogliomas represent the third most common type of glioma, comprising 4%–15% of all gliomas and can be classified by degree of malignancy into grade II and grade III, according to WHO classification. Only 30% of oligodendroglial tumors have anaplastic characteristics. Anaplastic oligodendroglioma (AO) is often localized as a single lesion in the white matter and in the cortex, rarely in brainstem or spinal cord. The management of AO is deeply changed in the recent years. Maximal safe surgical resection followed by radiotherapy (RT) was considered as the standard of care since paramount findings regarding molecular aspects, in particular co-deletion of the short arm of chromosome 1 and the long arm of chromosome 19, revealed that these subsets of AO, benefit in terms of overall

OPINION STATEMENT: Anaplastic oligodendroglial tumors have gained increasing interest with the emerging role of molecular markers and systemic chemotherapy during the past years. The long-term results of two landmark trials, RTOG 9402 and EORTC 26961, have resulted in a reconsideration of the appropriate therapeutic approaches for patients with these tumors. Both trials indicate that patients whose tumors harbor a 1p/19q co-deletion benefit particularly from the addition of procarbazine/lomustine (CCNU)/vincristine (PCV) chemotherapy to radiation therapy (RT). The median survival of patients with co-deleted tumors treated within the RTOG trial with PCV before irradiation was 14.7 years compared with 7.3 years of patients who received RT alone. Median overall survival has not been reached in the RT plus PCV arm of the EORTC trial, but a similar difference can be anticipated after a follow-up of more than 12 years. In contrast, no such benefit was observed for patients with tumors lacking 1p/19q ...
Mixed gliomas, such as oligoastrocytomas (OA), anaplastic oligoastrocytomas, and glioblastomas (GBMs) with an oligodendroglial component (GBMO) are defined as tumors composed of a mixture of two distinct neoplastic cell types, astrocytic and oligodendroglial. Recently, mutations ATRX and TP53, and codeletion of 1p/19q are shown to be genetic hallmarks of astrocytic and oligodendroglial tumors, respectively. Subsequent molecular analyses of mixed gliomas preferred the reclassification to either oligodendroglioma or astrocytoma. This study was designed to apply genetically integrated diagnostic criteria to mixed gliomas and determine usefulness and prognostic value of new classification in Korean patients ...
OBJECTIVES: I. Compare survival and time to first progression in patients with anaplastic oligodendroglioma treated with radiotherapy with or without adjuvant procarbazine, lomustine, and vincristine (PCV) following surgical resection. II. Investigate the effect of PCV on quality of life and neurologic function in these patients. III. Determine the toxicity of PCV in these patients. IV. Correlate chromosomal lesions (1p and/or 19q, 9p, p53 loss and mutation, amplification of chromosome 7, or loss of chromosome 10) with progression-free and overall survival in patients treated with these regimens.. OUTLINE: This is a randomized, multicenter study. Patients are stratified according to age, extent of resection, performance status, prior surgery, and participating center. Patients are randomized to one of two treatment arms. Arm I: Within 4-6 weeks after surgery, patients undergo radiotherapy over 7 weeks to the residual tumor volume. Arm II: Patients undergo radiotherapy as in arm I, then begin ...

These two tumour types comprise approximately one quarter of all gliomas with astrocytomas taking up the other three quarters.. What is the prognosis of patients with oligodendrogliomas? Oligodendrogliomas tend to be diagnosed more often than ependemyomas. The prognosis of patients with oliogodendrogliomas is better overall than that of patients with astrocytomas, however it worsens if the tumour progresses to the anaplastic stage. The evolution of oligodendrogliomas is similar to that of astrocytomas. If the tumour is caught in time, and treated, via means of surgery, the patient may be able to live up to ten years, and have a median survival rate of 5 years.. What do oligodendrogliomas appear like on the macroscopic and microscopic level? ...
Loss of heterozygosity (LOH) of the short arm of chromosome 1 (1p) and the long arm of chromosome 19 (19q) is an early event in oligodendroglioma that occurs in up to 80% of patients and is associated with therapeutic sensitivity and longer overall survival. The purpose of this study was to confirm the reported association in patients at this centre, then identify and characterise genes that were differentially expressed and may function as a tumour suppressor or contribute to therapeutic sensitivity in oligodendroglioma. A clinical review of oligodendroglioma patients treated at Royal North Shore and North Shore Private Hospitals between 1990 and 2009 confirmed the association between LOH 1p/19q and longer overall survival in WHO grade III oligodendroglioma patients. Younger age and lower tumour grade were additionally confirmed as positive prognostic factors. Exon microarrays were used to identify changes in gene expression between oligodendrogliomas with and without LOH 1p/19q. Seventeen ...

Stargardts disease (STGD), also known as fundus flavimaculatus (FFM), is an autosomal recessive retinal disorder characterized by a juvenile-onset macular dystrophy, alterations of the peripheral retina, and subretinal deposition of lipofuscin-like material. A gene encoding an ATP-binding cassette (ABC) transporter was mapped to the 2-cM (centiMorgan) interval at 1p13-p21 previously shown by linkage analysis to harbor the STGD gene. This gene, ABCR, is expressed exclusively and at high levels in the retina, in rod but not cone photoreceptors, as detected by in situ hybridization. Mutational analysis of ABCR in STGD families revealed a total of 19 different mutations including homozygous mutations in two families with consanguineous parentage. These data indicate that ABCR is the causal gene of STGD/FFM ...
Our primary finding for linkage to diabetic nephropathy is on chromosome 19q (triangle MLS = 3.1), with a secondary peak on chromosome 2q (triangle MLS = 2.1). The former, but not the latter, exceeds the Lander and Kruglyak criterion of triangle MLS ≥2.6 (17,18) for suggestive linkage. For reference, triangle MLS values of 3.3, 2.3, and 1.7 correspond to unadjusted P values of 0.0001, 0.001, and 0.005, respectively.. Stratification of DSPs based on proteinuria or ESRD suggested four tertiary peaks: linkage with ESRD on chromosome 1q (MLS = 1.8), linkage with proteinuria on chromosome 20p (MLS = 2.8), and linkage with two separate regions on chromosome 3q, one for proteinuria (MLS = 1.5) and another, 58 cM away, for ESRD (MLS = 1.1). We also found two chromosomal regions linked with type 1 diabetes. The most striking, not surprisingly, was on chromosome 6p (MLS = 9.2, 52 cM), confirming the well-established linkage with HLA. We also replicated IDDM15 on chromosome 6q (MLS = 3.1, 142 cM) ...
This is my first post as well so I will give you a little background first. I was diagnosed in September of 2003 with a grade II mixed Oligodendroglioma. I was given the option of doing nothing and taking a wait and see approach or being more aggressive and attempting to remove as much as possible with surgery. I chose the surgery option and they were able to remove about 2/3 of the tumor from my left frontal lobe. While I was on the table the surgeon spoke to my family and told them he could try to get the rest but he would have to remove so much good brain tissue that damage was likely and there was a large risk of me coming out of the surgery a different person. Fortunately my family made the right decision and decided against any further removal. I started Temodar in December of 2003 and continued that until February of 2006 with a lapse due to the onset of some severe side effects that required stopping treatment for about 4-5 months. My doctors were going to do radiation therapy but at the ...

Oligodendroglioma is characterized by unique clinical, pathological, and genetic features. Recurrent losses of chromosomes 1p and 19q are strongly associated with this brain cancer but knowledge of the identity and function of the genes affected by these alterations is limited. We performed exome sequencing on a discovery set of 16 oligodendrogliomas with 1p/19q co-deletion to identify new molecular features at base-pair resolution. As anticipated, there was a high rate of IDH mutations: all cases had mutations in either IDH1 (14/16) or IDH2 (2/16). In addition, we discovered somatic mutations and insertions/deletions in the CIC gene on chromosome 19q13.2 in 13/16 tumours. These discovery set mutations were validated by deep sequencing of 13 additional tumours, which revealed seven others with CIC mutations, thus bringing the overall mutation rate in oligodendrogliomas in this study to 20/29 (69%). In contrast, deep sequencing of astrocytomas and oligoastrocytomas without 1p/19q loss revealed ...
