Abstract
Background and Objectives: The objective of this paper is to compare the visual outcomes and quality of life (QoL) after bilateral ultrathin Descemet's stripping automated endothelial keratoplasty (UT-DSAEK) with bilateral penetrating keratoplasty (PK) for Fuchs' endothelial dystrophy (FED). Materials and Methods: Retrospective comparative cohort study, including 11 patients with FED who underwent bilateral PK and 13 patients with FED who underwent bilateral UT-DSAEK. All patients were already pseudophakic or had undergone a combined cataract procedure. The main outcomes were corrected distance visual acuity (CDVA) corneal higher-order aberrations (HOAs), contrast sensitivity (CS) and quality of life (QoL). Results: The mean follow-up after the second eye surgery was 32.5 ± 10.2 months in PK and 19.6 ± 8.6 months in UT-DSAEK patients. The CDVA in the UT-DSAEK group was significantly better than in the PK one (0.18 ± 0.07 vs. 0.35 ± 0.16 logMAR, p < 0.0001). The mean anterior corneal total HOAs of the central 5 mm were significantly lower in UT-DSAEK eyes than in PK eyes (0.438 ± 0.078 µ and 1.282 ± 0.330 µ respectively, p < 0.0001), whilst the mean posterior total HOAs did not differ between groups (0.196 ± 0.056 µ and 0.231 ± 0.089 µ, respectively, p = 0.253). The CS was lower at 0.75 and 1.5 cycles/degree in P the K group when compared to the DSAEK one (p = 0.008 and 0.005, respectively). The QoL scores by the NEI RQL-42 test exhibited better values in DSAEK patients in 9 out of 13 scales. Conclusion: Our study confirms that UT-DSAEK provides a better visual function in terms of CDVA and CS, together with lower HOAs, when compared to PK. Hence, the vision-related QoL, binocularly evaluated by the NEI RQL-42 items, indicates a higher satisfaction in UT-DSAEK eyes.

Abstract
Ex vivo limbal stem cell transplantation is the main therapeutic approach to address a complete and functional re-epithelialization in corneal blindness, the second most common eye disorder. Although important key points were defined, the molecular mechanisms involved in the epithelial phenotype determination are unclear. Our previous studies have demonstrated the pluripotency and immune-modulatory of fibroblast limbal stem cells (f-LSCs), isolated from the corneal limbus. We defined a proteomic profile especially enriched in wound healing and cytoskeleton-remodelling proteins, including Profilin-1 (PFN1). In this study we postulate that pfn-1 knock down promotes epithelial lineage by inhibiting the integrin-β1(CD29)/mTOR pathway and subsequent NANOG down-expression. We showed that it is possible modulate pfn1 expression levels by treating f-LSCs with Resveratrol (RSV), a natural compound: pfn1 decline is accompanied with up-regulation of the specific differentiation epithelial genes pax6 (paired-box 6), sox17 (sex determining region Y-box 17) and ΔNp63-α (p63 splice variant), consistent with drop-down of the principle stem gene levels. These results contribute to understand the molecular biology of corneal epithelium development and suggest that pfn1 is a potential molecular target for the treatment of corneal blindness based on epithelial cell dysfunction.

Abstract
Psoriasis affects about 2 to 3% of the caucasian population. It is a chronic inflammatory disease affecting predominantly the skin with the involvement of autoimmune mediated mechanisms. Typical pathogenic features include an increased renewal of epidermal keratinocytes, the enlargement of the germinating compartment, papillomatosis, altered epidermal differentiation, angiogenesis, lymphangiogenesis and inflammatory infiltration. Several types of psoriasis are distinguished and may be present simultaneously in some patients. Up to 20 candidate genes have been evidenced in psoriasis. Genetic variability explains different types of the disease and influences response to therapeutics. Furthermore, psoriasis is triggered or aggravated by infections, traumatisms, medications, stress, tobacco, alcohol and endocrine factors. Severe psoriasis is frequently associated with co-morbidities as obesity, diabetes, metabolic syndrome and cardiovascular diseases. For this reason, the similar pathogenic mechanisms of psoriasis and other IMID's (Immune Mediated Inflammatory Diseases) and the use of systemic treatments shared with other specialties, an updated vision of psoriasis for the internist is mandatory.

Abstract
The TNFalpha antagonists, including adalimumab, etanercept and infliximab, represent a class of anti-inflammatory and immunosuppressive drugs. Although cutaneous adverse effects are uncommon, they are varied. There is no particular risk profile to develop cutaneous adverse effects. The principal acute side effects are injection site reactions and pruritus. The major long term cutaneous side effects are infectious and inflammatory conditions. Neoplastic skin diseases are exceptional. The association with other immunosuppressive agents can increase the risk of developing cutaneous adverse effects. Some adverse effects, such as lupus erythematosus, require immediate withdrawal of the biological treatment, while in other cases temporary withdrawal is sufficient. The majority of the other cutaneous adverse effects can be dealt without interrupting biologic treatment. Preclinical and clinical investigations revealed that the new biologics, aiming IL12/23, IL23 and IL17, present a similar profile of cutaneous adverse effects, although inflammatory skin reactions may be less often encountered compared to TNFalpha antagonists.

Abstract
Topical treatment is the cornerstone of therapy for patients suffering from psoriasis. Its efficacy and safety have been demonstrated in a large number of publications. However, in daily life, the treatment outcome is often less satisfactory than the results published in the literature. This phenomenon is clearly linked to non-adherence. Indeed, patients with psoriasis frequently consider the topical therapies frequently as a heavy burden. The successful management of psoriasis with topical agents requires a perfect understanding between the patient and the practionner, which provides regular renewal of the patient's motivation.

Abstract
The increasing number of allergic subjects and the alteration of their quality of life are major concerns of public health. Symptomatic treatments of allergic diseases are not always able to improve the patient's complaints. Allergic exploration aims to identify IgE-dependant mechanisms and subsequently to prove the responsibility of the detected allergen in the allergic disease. The efficacy of the specific immunotherapy (SIT) using allergens in either subcutaneous or sublingual forms has been proven in rhinitis, conjunctivitis, asthma and IgE-induced reactions to hymenoptera venom. The lack of training in allergology is an important reticence of general practitioners and specialists to prescribe SIT. Furthermore, the duration of the treatment and its important cost in Belgium (where, only venom SIT is reimbursed by the Social Security) interfere significantly with the compliance of the patients.

Abstract
Allergic manifestations due to outdoor plants are relatively well known, contrary to those related to home plants. This review presents the various allergens linked to home plants that may be responsible for several allergic manifestations affecting the skin, the lungs, the eyes, and the rhinopharynx. The ficus and its family members constitute the principal sources of the incriminated allergens.

Abstract
The evolutionary relationship between telencephalic regions of the avian and mammalian brains has been a long-standing issue in comparative neuroanatomy. Based on various criteria, a number of homologous regions have been proposed. Recent studies in mammals have shown that basal regions of the telencephalon give rise to neurons that migrate dorsally and populate the cerebral cortex. In the present study we demonstrate that, similar to mammals, neurons from a ventricular region of the palaeo-striatal complex - the dorsal subpallial sulcus - of the chick telencephalon migrate dorsally to populate the developing pallium. Further characterization of these cells revealed that they express the neurotransmitter gamma-aminobutyric acid, but not the calcium-binding protein calbindin. These findings provide evidence that the mouse and chick basal regions are not only homologous in terms of gene expression patterns and connectivity, but they both also contribute inhibitory interneurons to dorsal regions of the developing telencephalon.
