Bilateral uveal pigmented alterations with remarkable evolution: long term follow-up in a case of possible bilateral diffuse uveal melanocytic proliferation

Purpose: to describe a case of probable bilateral diffuse uveal melanocytic proliferation (BDUMP) with scleral involvement, free from systemic malignancies and cataract. Methods: fifty months of follow up with recurrent complete ophthalmological examinations, including fundus photography, fluorescein/indocyanine green angiography (FA) and optical coherence tomography (OCT). Investigations also included an electroretinography (ERG) and histological examination of scleral biopsy. Extraocular malignancies were repeatedly searched. Results: the patient was a 61 year-old Italian man with chronic hepatitis type C. At first visit his best corrected visual acuity (BCVA) was 20/32 in OS and 20/25 in OD. Funduscopy showed multiple patch-shaped pigmented alterations involving macular region and mid retinal periphery. FA showed corresponding areas of late-phase hyperfluorescent pinpoints (figure 1a, OS) and intemediate-phase hypocyanescence (figure 1b, OS), with subtle serous neurosensory retinal detachment confirmed by OCT. Photopic and scotopic ERG tested normal. Systemic prednisone was administered for one month without any improvement. After ten months round pigmentary lesions appeared also in superior scleral surface of both eyes. Biopsy allowed to disclose slightly pigmented spindle cells. BCVA worsened for further 10 months, with enlargement of FA alteration areas but lenses still clear. After 30 months spontaneous coalescence and atrophy of retinal lesions started, paralleled by progressive visual recovery. At the end of our follow up BCVA was 20/25 in OU while scleral pigmentary lesions remained unchanged. Conclusions: we report the case of a patient with main features of BDUMP and some unusual findings. Although not all classical diagnostic criteria were fulfilled, the presence of scleral pigmented lesions and spontaneous visual recovery may enlarge clinical spectrum of the disease.

Sustained improvement in left ventricular function after bone marrow derived cell therapy in patients with acute ST elevation myocardial infarction. A 5-year follow-up from the Stem Cell Transplantation in Ischaemic Myocardium Study.

BACKGROUND: Intracoronary injection of autologous bone marrow-derived mononucleated cells (BM-MNC) may improve LV function shortly after acute ST elevation myocardial infarction (STEMI), but little is known about the long-term durability of the treatment effect. METHODS: In a single-centre trial a total of 60 patients with acute anterior STEMI, successful reperfusion therapy and a left ventricular ejection fraction (LVEF) of <50% were screened for the study. 23 patients were actively treated with intracoronary infusion of BM-MNC within a median of 3 days. The open-label control group consisted of 19 patients who did not consent to undergo BM-MNC treatment but agreed to undergo regular clinical and echocardiographic follow-up for up to 5 years after AMI. RESULTS: Whereas at 4 months there was no significant difference between the increase in LVEF in the BM-MNC group and the control group (+7.0%, 95%CI 3.6; 10.4) vs. +3.9%, 95%CI -2.1; 10), the absolute increase at 5 years remained stable in the BM-MNC but not in the control group (+7.95%, 95%CI 3.5; 12.4 vs. -0.5%, 95%CI -5.4; 4.4; p for interaction between groups = 0.035). DISCUSSION: In this single-centre, open-labelled study, intracoronary administration of BM-MNC is feasible and safe in the short term. It is also associated with sustained improvement of left ventricular function in patients with acute myocardial infarction, encouraging phase III studies to examine the potential BM-MNC effect on clinical outcome.

High and low doses of antimony (Sb v) in American cutaneous leishmaniasis: a five years follow-up study of 15 patients

Seventeen patients proceeding from the municipality of Rio de Janeiro, Brazil presenting with the cutaneous ulcerative form of American leishmaniasis were treated with one ampoule of pentavalent antimony daily for 30 days. With this regimen the individuals doses varies greatly: from 3.8 mg/kg of body weight to 22.3 mg/kg. After five years, patients receiving either a smaller dose or a bigger one, showed the same therapeutic result: cutaneous scars and no mucosal lesions.

Encoding dysfunctions in a dynamic-static paradigm for visuospatial working memory in first-episode psychosis patients: a 2-year follow-up study.

Aim: To investigate static and dynamic visuospatial working memory (VSWM) processes in first-episode psychosis (FEP) patients and explore the validity of such measures as specific trait markers of schizophrenia. Methods: Twenty FEP patients and 20 age-, sex-, laterality- and education-matched controls carried out a dynamic and static VSWM paradigm. At 2-year follow up 13 patients met Diagnostic and Statistical Manual (of Mental Health Disorders) - Fourth Edition (DSM-IV) criteria for schizophrenia, 1 for bipolar disorder, 1 for brief psychotic episode and 5 for schizotypal personality disorder. Results: Compared with controls, the 20 FEP patients showed severe impairment in the dynamic VSWM condition but much less impairment in the static condition. No specific bias in stimulus selection was detected in the two tasks. Two-year follow-up evaluations suggested poorer baseline scores on the dynamic task clearly differentiated the 13 FEP patients who developed schizophrenia from the seven who did not. Conclusions: Results suggest deficits in VSWM in FEP patients. Specific exploratory analyses further suggest that deficit in monitoring-manipulation VSWM processes, especially involved in our dynamic VSWM task, can be a reliable marker of schizophrenia.

Long-term follow-up of four patients with Langer-Giedion syndrome: clinical course and complications.

Long-term observations of individuals with the so-called Langer-Giedion (LGS) or tricho-rhino-phalangeal type II (TRPS2) are scarce. We report here a on follow-up of four LGS individuals, including one first described by Andres Giedion in 1969, and review the sparse publications on adults with this syndrome which comprises ectodermal dysplasia, multiple cone-shaped epiphyses prior to puberty, multiple cartilaginous exostoses, and mostly mild intellectual impairment. LGS is caused by deletion of the chromosomal segment 8q24.11-q24.13 containing among others the genes EXT1 and TRPS1. Most patients with TRPS2 are only borderline or mildly cognitively delayed, and few are of normal intelligence. Their practical skills are better than their intellectual capability, and, for this reason and because of their low self-esteem, they are often underestimated. Some patients develop seizures at variable age. Osteomas on processes of cervical vertebrae may cause pressure on cervical nerves or dissection of cerebral arteries. Joint stiffness is observed during childhood and changes later to joint laxity causing instability and proneness to trauma. Perthes disease is not rare. Almost all males become bald at or soon after puberty, and some develop (pseudo) gynecomastia. Growth hormone deficiency was found in a few patients, TSH deficiency so far only in one. Puberty and fertility are diminished, and no instance of transmission of the deletion from a non-mosaic parent to a child has been observed so far. Several affected females had vaginal atresia with consequent hydrometrocolpos.

Neuro-developmental follow-up of neonates treated with magnesium sulfate for persistent pulmonary hypertension

Rapport de synthèse : DEVENIR NEURO-DEVELOPPEMENTAL DE NOUVEAU-NES TRAITES PAR DU SULFATE DE MAGNESIUM POUR UNE HYPERTENSION PULMONAIRE PERSISTANTE L'hypertension pulmonaire persistante du nouveau-né (HTPP) est un trouble de l'adaptation post-natale de la circulation pulmonaire caractérisé par une défaillance de la diminution normale des résistances vasculaires pulmonaires, accompagné d'un shunt droite-gauche, résultant en une hypoxémie profonde. C'est une pathologie sévère nécessitant des soins intensifs avec un risque augmenté de handicaps neurologiques chez les survivants. Le traitement de l'HTPP du nouveau-né inclut une ventilation mécanique ainsi que différents agents pharmacologiques pour dilater les vaisseaux pulmonaires, dont le sulfate de magnésium (MgSO4) à hautes doses par voie intraveineuse et le monoxyde d'azote par voie inhalée (iN0). Le MgSO4 est une alternative thérapeutique de l'HTPP du nouveau-né avec peu d'effets secondaires et une mortalité basse. Il a aussi été démontré que le MgSO4 est un traitement de l'HTPP du nouveau-né autant efficace que le iN0 et moins coüteux. Des études sur le suivi neuro-développemental de nouveau-nés avec HTPP traités selon différentes méthodes ont été publiées reportant des taux élevés de handicaps majeurs et mineurs. Plus récemment, des études de suivi après traitement par iN0 ont montré des taux plus bas qu'avec des traitements antérieurs. Le devenir neuro-développemental àlong terme d'enfants traités avec du MgSO4 n'a pas été documenté. Le but de cette étude est de décrire le développement des enfants qui ont présenté une HTPP traitée seulement avec du MgS04, de reporter l'incidence de handicaps majeurs et mineurs, et de les comparer à un groupe contrôle d'enfants sains du même âge ainsi qu'aux données de la littérature. La population consiste en 33 nouveau-nés traités pour une HTPP avec seulement du MgSO4 (groupe étude) et 32 nouveau-nés à terme sains (groupe contrôle). Un suivi neurodéveloppemental standardisé et approfondi a été effectué aux âges clés de 18 mois et 5 ans. Les taux de handicaps majeurs à 18 mois et 5 ans dans le groupe étude étaient de 6% et 11,4% respectivement, et de 0% aux deux âges dans le groupe contrôle. Les taux de handicaps mineurs aux mêmes âges étaient de 3% et 26,9% pour le groupe étude, et de 0% et 26,1% pour le groupe contrôle. Les quotients développementaux moyens à 18 mois étaient de 106,6 (DS 1,6) dans le groupe étude et de 118,3 (DS 1,0) dans le groupe contrôle (P < 0,001). L'index général intellectuel en âge préscolaire était de 112.6 (DS 3.7), respectivement de 119.3 (DS 3.1 ), sans différence significative entre les deux groupes. A 18 mois, les taux de handicaps majeurs et mineurs dans les groupes études et contrôle étaient de 6% et 3%. Dans la littérature, des taux entre 0% et 33% ont été décrits. A cet âge, il y avait une différence significative pour tous les scores du test de Griffiths, mëme en tenant compte du status socio-économique de la famille. Ceci suggère un léger retard du développement global et non une altération spécifique. Ces différences n'étaient plus significatives en âge préscolaire, suggérant un rattrapage développemental. Le taux de handicaps majeurs en âge préscolaire pour le groupe étude était de 11.5%, sans aucune infirmité motrice cérébrale. Ces résultats correspondent à ceux d'études de suivi après d'autres traitements jusqu'à l'âge de 24 mois avec des taux variant de 0% à 15%. Le taux de handicaps mineurs était de 26.9% dans le groupe étude et de 26.1% dans le groupe contrôle, sans différence significative entre les deux groupes. L'incidence de handicaps mineurs dans le groupe étude était plutôt élevée en comparaison aux données de la littérature (6 à 22% à 6 ans). Une explication possible est que nous avons considéré des problèmes de langage et de comportement comme handicaps mineurs. Ceci suggère une différence méthodologique et non une plus mauvaise issue dans nos deux groupes. Les évaluations cognitives des enfants des deux groupes se trouvaient dans la norme, ce qui est aussi le cas dans la littérature. En conclusion, cette étude longitudinale non randomisée d'enfants traités avec du MgSO4 seul pour une HTPP sévère ne montre pas de conséquences sur le devenir neuro-développemental à long terme. Cette étude le démontre pour la première fois. Malgré le fait que iN0 soit le traitement actuellement recommandé pour l'HTPP du nopuveau-né, le MgSO4 reste largement utilisé, en particulier dans des pays en voie de développement. L'absence de complications neuro-développementales majeures à long terme permet de considérer l'administration du MgSO4 pour le traitement de l'HTPP du nouveau-né en cas de non réponse ou d'inaccessibilité au iNO.

Solitary fibrous tumor of the lateral ventricle: CT appearances and pathologic correlation with follow-up.

Intracranial solitary fibrous tumors are rare, and intraventricular fibrous tumors are even more unusual. We report a case of solitary fibrous tumor in the region of trigone and body of the left lateral ventricle and discuss the clinical presentation, CT characteristics, and histopathologic features with 1-year follow-up. We speculate that the tumor arose from the perivascular connective tissue of the choroid plexus.

The role of ceramide trihexoside (globotriaosylceramide) in the diagnosis and follow-up of the efficacy of treatment of Fabry disease: a review of the literature.

Fabry disease is caused by a deficiency of a-galactosidase A which leads to the progressive intra-lysosomal accumulation of ceramide trihexoside (CTH), also known as globotriaosylceramide (Gb3), in different cell types and body fluids. The clinical manifestations are multisystemic and predominantly affect the heart, kidney and central nervous system. The role of CTH in the pathophysiological process of Fabry disease is not established, and the link between the degree of accumulation and disease manifestations is not systematic. The use of CTH as a diagnostic tool has been proposed for several decades. The recent introduction of a specific treatment for Fabry disease in the form of enzyme replacement therapy (ERT) has led to the need for a biological marker, in place of a clinical sign, for evaluating the efficacy of treatment and also as a tool for following the long term effects of treatment. The ideal biomarker must adhere to strict criteria, and there should be a correlation between the degree of clinical efficacy of treatment and a change in its concentration. This review of the literature assesses the utility of CTH as a diagnostic tool and as a marker of the efficacy of ERT in patients with Fabry disease. Several techniques have been developed for measuring CTH; the principles and the sensitivity thresholds of these methods and the units used to express the results should be taken into consideration when interpreting data. The use of CTH measurement in Fabry disease should be re-evaluated in light of recent published data.

Congenital Myasthenic Syndromes with COLQ mutations: Long term follow-up

Congenital myasthenic syndromes (CMS) are clinically and genetically heterogeneous inherited disorders characterized by impaired neuromuscular transmission. Mutations in the acetylcholinesterase (AChE) collagenlike tail subunit gene (ColQ) cause recessive forms of synaptic CMS with end plate AChE deficiency. We report the time course of clinical manifestations in 15 COLQ-mutated patients followed from 1987 to 2010. All patients suffered from a muscle weakness with onset at birth or in childhood. Ocular and bulbar signs were found in 60% of the patients and delayed pupillary light response in 20% of our patients. EMG study demonstrated a decrement on repetitive nerve stimulation and repetitive compound muscle action potential in all patients. Clinical symptoms strongly fluctuated daily, weekly, monthly or even yearly. Severe relapses were characterized by a general motor weakness associated with pain which resolved spontaneously after a few months whereas the relapses with these symptoms and bulbar signs could last up to several years. Genetic analyses identified 16 different mutations including 9 novel ones. There was no genotype-phenotype correlation. Our study confirms the predominance of oculobulbar signs and the frequency of respiratory distress in COLQrelated CMS. At the end of the follow up of 23 years, interesting findings were (i) the spontaneous reversibility of severe relapses, some of them lasting for up to 5 years (ii) the good prognosis of COLQ-related CMS, since at the end of the follow-up 80% of patients were ambulant and 87% of patients had no respiratory trouble (iii) the efficacy of Ephedrine and, to a lesser extend, of 3-4 DAP. The triggering factors of relapses were esterase inhibitors, effort, puberty, pregnancy and delivery highlighting the importance of hormonal factors in CMS. In conclusion, patients diagnosed with unknown congenital myopathy should undergo an electrophysiological study of neuromuscular junction to identify ColQ-related CMS.
