Abstract
Purpose The risk of infection can be reduced in hemodialysis (HD) patients with central venous catheters (CVCs) by using prophylactic intranasal mupirocin or polysporin at the exit site. However, there are concerns about the potential emergence of resistant microorganisms. The purpose of our study was to determine if the use of polysporin double in the treatment of exit site infections was associated with the emergence of yeast positive exit site cultures. Methods In this case control study, we evaluated the risk of developing yeast positive exit site cultures after introducing a polysporin medical directive for the treatment of presumed exit site infections in our HD units. All HD patients using a CVC for blood access at the Ottawa Hospital were eligible for study. Demographic variables, use of polysporin, antibiotics and immunosuppressive medications were compared between those patients with yeast positive exit site cultures and controls. Results There was no differences in age, gender or diabetic status between the cases and controls. However, the use of polysporin, antibiotics and immunocompromised status were associated with an increased risk of yeast positive exit site cultures. The relative importance of each of these factors could not be determined using this study design and requires future prospective study. Conclusions The emergence of yeast positive exit site cultures after the introduction of a new medical directive at a tertiary care hospital highlights the difference between medications used for prophylaxis and those used for treatment of CVC infections in high risk dialysis patients.

Abstract
OBJECTIVE We recently showed the superiority of a matrix metalloproteinase (MMP) modulating dressing (foam impregnated with NOSF, nano-oligosaccharide factor) compared with a lipidocolloid matrix (TLC) control dressing in median wound area reduction (WAR). Here we report the results from the same study assessing the performance and safety of TLC-NOSF in the local management of venous leg ulcers (VLUs) or mixed leg ulcers and determining its impact on the patient's health-related quality of life (HRQoL). METHOD A superiority randomised double-blind controlled trial was conducted on patients presenting with a non-infected leg ulcer (VLUs or mixed leg ulcers) of predominantly venous origin (ABPI >0.8), with a surface area ranging from 5 to 50cm2 and a duration of 6 to 36 months. Patients were randomly allocated to either the TLC-NOSF matrix foam (UrgoStart) dressing group or to the neutral TLC foam dressing group (UrgoTul Absorb). All received appropriate compression therapy and the wounds were assessed blindly (clinical examination, wound area tracing and photographic record) every 2 weeks for a period of 8 weeks, or until complete closure. A secondary endpoint, described here, was the patient's HRQoL, documented by the patient, through the EuroQol 5D tool (EQ-5D) questionnaire and visual analogue scale (VAS). RESULTS In total, 187 patients were randomised to either the TLC-NOSF group (n=94) or the control dressing group (n=93). The two groups were well balanced at baseline with regard to wound and patient characteristics. In the HRQoL questionnaire (EQ-5D), the pain/discomfort and anxiety/depression dimensions were significantly improved in the TLC-NOSF group versus the control one (pain/discomfort: 1.53±0.53 versus 1.74±0.65; p=0.022, and anxiety/depression: 1.35±0.53 versus 1.54±0.60, p=0.037). The VAS score was better in the test group compared with the control group (72.1±17.5 versus 67.3±18.7, respectively), without reaching significance (p=0.072). Acceptability and tolerance of the two products were similar in both groups. CONCLUSION The double-blind clinical trial has demonstrated that the TLC-NOSF matrix dressing promotes faster healing of VLUs and mixed leg ulcers and significantly reduces the pain/discomfort and anxiety/depression experienced by the patients. These results suggest that acceleration of VLU healing could improve the HRQoL of the patients and reduced the emotional and social burden of these chronic wounds.

Abstract
BACKGROUND Linear IgA bullous dermatosis (LABD) is an autoimmune blistering skin disorder characterized by linear IgA deposits along the dermoepidermal junction. Usually idiopathic, LABD can be drug-induced. OBJECTIVE To report the atypical characteristics of a case of trimethoprim-sulfamethoxazole-induced LABD presenting as toxic epidermal necrolysis (TEN). METHODS A 63-year-old woman treated with trimethoprim-sulfamethoxazole for Pneumocystis jirovecii infection developed a generalized maculopapular rash with herpetiform lesions, rosette-like lesions, and tense bullae with Nikolsky sign. RESULTS Anti-basement membrane zone antibodies were negative, but immunoblot revealed a 160 kDa band corresponding to subepidermal class IgA desmoglein 1. Skin biopsy specimens revealed a subepidermal bulla and direct immunofluorescence showed linear IgA deposition along the basement membrane zone. A diagnosis of toxic epidermal necrolysis was excluded and replaced by trimethoprim-sulfamethoxazole-induced LABD. CONCLUSION We report a case of trimethoprim-sulfamethoxazole-induced LABD with a 160 kDa IgA desmoglein 1 found by immunoblotting analysis, probably by epitope spreading.

Abstract
Monilethrix is a rare genodermatosis characterized by a hair shaft dysplasia responsible for hypotrichosis. We report the case of a child with monilethrix with no associated cases in the family. Trichoscopy facilitated the diagnosis. A 2-year-old boy presented with diffuse alopecia and persistent fragile hair for several months. Clinical examination revealed alopecia with hairs broken several millimeters from the scalp. Trichoscopy revealed zones of dystrophic constriction of the hair shaft, separated at regular intervals by elliptical nodes of normal thickness, giving a "necklace" appearance. The diagnosis of monilethrix was made on the basis of these specific features. The diagnosis of monilethrix was more difficult to establish in our patient owing to the absence of any familial cases.

Abstract
Zika virus: what the dermatologist should know. Probably a new vaccine against herpes zoster and postherpetic neuralgia in older adults. Defining moderate, significant and extensive types of pemphigus with ABSIS et PDAI scores. Biologic Therapies and serious infections in patients with psoriasis. We can be cautiously optimistic, in that tuberculosis is rare but still occurs despite adherence to tuberculosis prevention guidelines. Others serious infections are rare, mainly pneumonia and cellulitis. Hidradenitis suppurativa: an unrecognized paradoxical effect of biologic agents. There is an association between Inflammatory Bowel Disease (IBD) and Hidradenitis suppurativa (HS), mostly with Crohn's disease, suggesting the need to look for signs and symptoms of IBD in HS patients. A study of 550 twins found that genetic and environmental factors each contribute to approximately half of the score of rosacea. Telangiectasia Macularis Eruptiva Perstans is a difficult to diagnose type of mastocytosis, often with a delay and which is associated with a systemic involvement in 50% of cases. Vitiligo. Management and development of new scores for the dermatologist and the patient. Livedoid vasculopathy. Anticoagulation with new molecules could prove an efficient means of treatment. Pyoderma Gangrenosum. Don't forget the toxic etiology. Daily practice: Laboratory monitoring for liver function tests and serum lipid profile during isotretinoin therapy for acne is currently recommended at baseline and every 3 months, depending on the results. Daily practice: Mikailov and al., challenge our habits by their medico economic study and propose an empirical treatment with terbinafine for patients with suspected onychomycosis that is cost effective with minimal effect on patient safety as terbinafine-induced liver injury is very rare. It makes think and especially propose studies to update our recommendations.
