The current number of fungal infections occurring each year in Turkey is unknown. We estimated the burden of serious human fungal diseases based on the population at risk, existing epidemiological data from 1920 to 2017 and modelling previously described by the LIFE program (http://www.LIFE-worldwide.org). Among the population of Turkey (80.8 million in 2017), approximately 1 785 811 (2.21%) people are estimated to suffer from a serious fungal infection each year. The model used predicts high prevalences of allergic fungal rhinosinusitis episodes (312 994 cases) (392/100 000), of severe asthma with fungal sensitisation (42 989 cases) (53.20 cases/100 000 adults per year), of allergic bronchopulmonary aspergillosis (32 594 cases) (40.33/100 000), of fungal keratitis (26 671 cases) (33/100 000) and of chronic pulmonary aspergillosis (5890 cases) (7.29/100 000). The estimated annual incidence for invasive aspergillosis is lower (3911 cases) (4.84/100 000 annually). Among about 22.5 million women aged 15-50 years, recurrent vulvovaginal candidiasis is estimated to occur in 1 350 371 (3342/100 000) females. The burden of three superficial fungal infections was also estimated: tinea pedis (1.79 million), tinea capitis (43 900) and onychomycosis (1.73 million). Given that the modelling estimates reported in the current study might be substantially under- or overestimated, formal epidemiological and comprehensive surveillance studies are required to validate or modify these estimates.

Seminars in Arthritis and Rheumatism Apr 2019To determine characteristics of the foot and ankle in people with systemic lupus erythematosus (SLE). (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To determine characteristics of the foot and ankle in people with systemic lupus erythematosus (SLE).
METHODS
Medline, CINAHL, Sports-Discus, Scopus and Cochrane Library databases were searched up to January 2018. Studies reporting foot- and ankle-related outcomes in the following domains were included: vascular, neurological, musculoskeletal, cutaneous (skin and nail) or pain/function. The Quality Index tool was used to assess methodological quality. Where appropriate, odds ratio (OR) and mean difference meta-analyses were conducted for case-control studies; and pooled mean prevalence meta-analyses for studies assessing characteristics in SLE.
RESULTS
Forty-nine studies were included with mean (range) quality scores of 75% (38-100%). Twenty-three studies assessed vascular characteristics, followed by musculoskeletal (n = 16), neurological (n = 11), cutaneous (n = 5) and pain/function (n = 4). Foot and ankle characteristics in people with SLE included impaired vascular supply, abnormal nerve function, musculoskeletal pathology, skin and nail pathology, and pain and functional disability. Twenty-four studies were included in meta-analyses. Pooled OR for abnormal ankle brachial index was 3.08 for SLE compared with controls. Pooled mean difference in brachial-ankle pulse-wave velocity between SLE and controls was significant (161.39 cm/s, P = 0.004). Pooled prevalence was 0.54 for intermittent claudication, 0.50 for Raynaud's phenomenon, 0.28 for chilblains, 0.00 for gangrene, 0.30 for hallux valgus, 0.15 for onychomycosis, 0.76 for history of foot pain, and 0.36 for current foot pain.
CONCLUSION
People with SLE experience a wide range of foot and ankle manifestations. Published research highlights the impact of peripheral arterial disease, peripheral neuropathy, musculoskeletal deformity, skin and nail pathology and patient-reported foot pain and disability.

BACKGROUND
Identifying the source of an outbreak is the most crucial aspect of any outbreak investigation. In this review, we address the frequently discussed question of whether (rectal) screening of health care workers (HCWs) should be carried out when dealing with outbreaks caused by gram negative bacteria (GNB).A systematic search of the medical literature was performed, including the Worldwide Outbreak Database and PubMed. Outbreaks got included if a HCW was the source of the outbreak and the causative pathogen was an , ., ., ., , or This was true for 25 articles in which there were 1196 (2.1%) outbreaks due to GNB, thereof 14 HCWs who were permanently colonized by the outbreak strain. Rectal screening of HCWs was helpful in only 2 of the 1196 (0.2%) outbreaks. Instead, the hands of HCWs served as a reservoir for the outbreak strain in at least 7 articles - especially when they suffered from onychomycosis or used artificial fingernails or rings.
CONCLUSION
Due to very weak evidence, we do not recommend rectal screening of HCWs in an outbreak situation with GNB. However, besides a critical review of hand hygiene habits, it might be useful to examine the hands of staff carefully. This measure is cheap, quick to perform, and seems to be quite effective.

Meta-Analysis Review
BACKGROUND
Fungal infection of the toenails, also called onychomycosis, is a common problem that causes damage to the nail's structure and physical appearance. For those severely affected, it can interfere with normal daily activities. Treatment is taken orally or applied topically; however, traditionally topical treatments have low success rates due to the nail's physical properties. Oral treatments also appear to have shorter treatment times and better cure rates. Our review will assist those needing to make an evidence-based choice for treatment.
OBJECTIVES
To assess the effects of oral antifungal treatments for toenail onychomycosis.
SEARCH METHODS
We searched the following databases up to October 2016: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers and checked the reference lists of included and excluded studies for further references to relevant randomised controlled trials (RCTs). We sought to identify unpublished and ongoing trials by correspondence with authors and by contacting relevant pharmaceutical companies.
SELECTION CRITERIA
RCTs comparing oral antifungal treatment to placebo or another oral antifungal treatment in participants with toenail onychomycosis, confirmed by one or more positive cultures, direct microscopy of fungal elements, or histological examination of the nail.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane.
MAIN RESULTS
We included 48 studies involving 10,200 participants. Half the studies took place in more than one centre and were conducted in outpatient dermatology settings. The participants mainly had subungual fungal infection of the toenails. Study duration ranged from 4 months to 2 years.We assessed one study as being at low risk of bias in all domains and 18 studies as being at high risk of bias in at least one domain. The most common high-risk domain was 'blinding of personnel and participants'.We found high-quality evidence that terbinafine is more effective than placebo for achieving clinical cure (risk ratio (RR) 6.00, 95% confidence interval (CI) 3.96 to 9.08, 8 studies, 1006 participants) and mycological cure (RR 4.53, 95% CI 2.47 to 8.33, 8 studies, 1006 participants). Adverse events amongst terbinafine-treated participants included gastrointestinal symptoms, infections, and headache, but there was probably no significant difference in their risk between the groups (RR 1.13, 95% CI 0.87 to 1.47, 4 studies, 399 participants, moderate-quality evidence).There was high-quality evidence that azoles were more effective than placebo for achieving clinical cure (RR 22.18, 95% CI 12.63 to 38.95, 9 studies, 3440 participants) and mycological cure (RR 5.86, 95% CI 3.23 to 10.62, 9 studies, 3440 participants). There were slightly more adverse events in the azole group (the most common being headache, flu-like symptoms, and nausea), but the difference was probably not significant (RR 1.04, 95% CI 0.97 to 1.12; 9 studies, 3441 participants, moderate-quality evidence).Terbinafine and azoles may lower the recurrence rate when compared, individually, to placebo (RR 0.05, 95% CI 0.01 to 0.38, 1 study, 35 participants; RR 0.55, 95% CI 0.29 to 1.07, 1 study, 26 participants, respectively; both low-quality evidence).There is moderate-quality evidence that terbinafine was probably more effective than azoles for achieving clinical cure (RR 0.82, 95% CI 0.72 to 0.95, 15 studies, 2168 participants) and mycological cure (RR 0.77, 95% CI 0.68 to 0.88, 17 studies, 2544 participants). There was probably no difference in the risk of adverse events (RR 1.00, 95% CI 0.86 to 1.17; 9 studies, 1762 participants, moderate-quality evidence) between the two groups, and there may be no difference in recurrence rate (RR 1.11, 95% CI 0.68 to 1.79, 5 studies, 282 participants, low-quality evidence). Common adverse events in both groups included headache, viral infection, and nausea.Moderate-quality evidence shows that azoles and griseofulvin probably had similar efficacy for achieving clinical cure (RR 0.94, 95% CI 0.45 to 1.96, 5 studies, 222 participants) and mycological cure (RR 0.87, 95% CI 0.50 to 1.51, 5 studies, 222 participants). However, the risk of adverse events was probably higher in the griseofulvin group (RR 2.41, 95% CI 1.56 to 3.73, 2 studies, 143 participants, moderate-quality evidence), with the most common being gastrointestinal disturbance and allergic reaction (in griseofulvin-treated participants) along with nausea and vomiting (in azole-treated participants). Very low-quality evidence means we are uncertain about this comparison's impact on recurrence rate (RR 4.00, 0.26 to 61.76, 1 study, 7 participants).There is low-quality evidence that terbinafine may be more effective than griseofulvin in terms of clinical cure (RR 0.32, 95% CI 0.14 to 0.72, 4 studies, 270 participants) and mycological cure (RR 0.64, 95% CI 0.46 to 0.90, 5 studies, 465 participants), and griseofulvin was associated with a higher risk of adverse events, although this was based on low-quality evidence (RR 2.09, 95% CI 1.15 to 3.82, 2 studies, 100 participants). Common adverse events included headache and stomach problems (in griseofulvin-treated participants) as well as taste loss and nausea (in terbinafine-treated participants). No studies addressed recurrence rate for this comparison.No study addressed quality of life.
AUTHORS' CONCLUSIONS
We found high-quality evidence that compared to placebo, terbinafine and azoles are effective treatments for the mycological and clinical cure of onychomycosis, with moderate-quality evidence of excess harm. However, terbinafine probably leads to better cure rates than azoles with the same risk of adverse events (moderate-quality evidence).Azole and griseofulvin were shown to probably have a similar effect on cure, but more adverse events appeared to occur with the latter (moderate-quality evidence). Terbinafine may improve cure and be associated with fewer adverse effects when compared to griseofulvin (low-quality evidence).Only four comparisons assessed recurrence rate: low-quality evidence found that terbinafine or azoles may lower the recurrence rate when compared to placebo, but there may be no difference between them.Only a limited number of studies reported adverse events, and the severity of the events was not taken into account.Overall, the quality of the evidence varied widely from high to very low depending on the outcome and comparison. The main reasons to downgrade evidence were limitations in study design, such as unclear allocation concealment and randomisation as well as lack of blinding.

Meta-Analysis Review
BACKGROUND
Onychomycosis is a highly prevalent disease worldwide. There is no standard test for its diagnosis, which remains costly, wasteful, and is sometimes delayed. The diagnostic tests for this disease are few and discordant. The objective was to evaluate the diagnostic validity, performance, and accuracy of culture, nail clipping with Periodic Acid-Schiff -PAS- staining (biopsy), and direct potassium hydroxide (KOH) examination for the study of onychomycosis.
METHODS
A systematic review was conducted via meta-analysis using 5 databases and 21 search strategies. An ex ante protocol was applied with inclusion and exclusion criteria. Quality was assessed with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool, and the sensitivity, specificity, predictive values, likelihood ratios, diagnostic odds ratios, receiver operating characteristic (ROC) curves, and proportion of correctly diagnosed patients were evaluated with the meta-analysis of studies of evaluations of diagnostic and screening tests (Meta-DiSc) and Epidat using a random effects model.
RESULTS
The efficiency or accuracy of the three tests is influenced by the methodological quality of the studies. These values are lower for KOH and culture and higher for biopsy in moderate quality studies.
CONCLUSION
The diagnostic tests evaluated in this meta-analysis independently showed acceptable validity, performance, and efficiency, with nail clipping with PAS staining outperforming the other two tests.

Comparative Study Meta-Analysis Review
The efficacy and safety of amorolfine 5% nail lacquer in combination with systemic antifungal agents in the treatment of the onychomycosis were evaluated. According to our meta-analysis, combination treatment of amorolfine 5% nail lacquer and systemic antifungals can result in higher percentage of complete clearance of onychomycosis. It showed that the experimental combination group was more effective than monotherapy of the systemic antifungals [OR (odds ratio) = 1.97, 95%CI (95% confidence interval) = 1.44-2.69], and no more adverse events happened with the addition of amorolfine 5% nail lacquer (OR = .96, 95%CI = .56-1.63, p = .95). This effect strengthens the fact that amorolfine 5% nail lacquer in combination with systemic antifungal agents was better than the monotherapy of systemic antifungals like itraconazole and terbinafine.

Review
BACKGROUND
Skin conditions and dermatological diseases associated with advanced age (e.g. fungal infection, dry skin and itch) receive increasingly attention in clinical practice and research. Cost and economic evaluations are important sources to inform priority setting and ressource allocation decisions in healthcare. The economics of skin conditions in aged populations has not been systematically reviewed so far.
OBJECTIVES
The aim of this mapping review was to summarize the economic evidence of selected skin conditions in the aged (65 + years).
METHODS
A mapping literature review and evidence summary was conducted. Searches were conducted in data bases Medline and Embase via OVID. Cinahl was searched using EBSCO. References lists of potential eligible studies, reviews, guidelines or other sources were screened for additional literature. For evaluation of methodological quality of full economic analyses the Consensus on Health Economic Criteria (CHEC) checklist was used.
RESULTS
Database searches resulted in 1388 records. A total of 270 articles were read in full-text. Thirty-five publications were finally included in the data analysis reporting 38 economic analyses. Ten cost of illness analyses and 26 cost-effectiveness analyses reporting about pressure ulcers, skin tears, pressure ulcers, incontinence associated dermatitis and intertrigo/contact dermatitis/candidiasis treatment and prevention and onychomycosis testing were identified. Limited evidence indicated that low air loss beds were more cost effective than standard beds for prevention of pressure ulcers. Standardized skin care regimens seem to lower the incidence of pressure ulcers, skin tears and IAD but a cost saving effect was not always observed.
CONCLUSIONS
Findings of this mapping review indicate that there is a paucity of high quality evidence regarding the economic impact of age-associated skin conditions and diseases. Substantial heterogeneity in terms of study design, evaluation perspective, time period, and way of cost estimation was identified. Because of the overall low methodological quality clear cut conclusions cannot be drawn. Robust and large scales economic evaluations about skin conditions and disease in aged populations are needed in the future.

Review
Other than a cosmetic concern, Onychomycosis is also a prevalent nail disease, which is extremely difficult to treat, and sometimes is refractory to conventional therapy. Moreover, many patients are not eligible to take oral antifungals owing to polypharmacy and comorbidities. Systemic side effects seen with oral antifungals have lead to patient nonadherence and adverse events. Therefore, newer therapies are being investigated for onychomycosis that would be free of systemic complications posed by oral therapy. Photodynamic therapy (PDT) is one of those being currently studied, which involves the use of photosensitizer and a light source to excite the photosensitizer to generate reactive oxygen species. The present review will put some light on PDT as an upcoming treatment modality for onychomycosis. We performed a systematic review of the literature to find the articles relevant to the use of PDT for onychomycosis. From the primary search of 43 articles, 17 papers are included in this review.

Review
BACKGROUND
Onychomycosis is a difficult-to-treat infection whose current treatment paradigm relies primarily on oral antifungals. The emergence of new topical drugs broadens the therapeutic options and prompts a re-evaluation of the current Canadian treatment strategy.
OBJECTIVE
To define a patient-centred Canadian treatment strategy for onychomycosis.
METHODS
An expert panel of doctors who treat onychomycosis was convened. A systematic review of the literature on treatments for onychomycosis was conducted. Based on the results, a survey was designed to determine a consensus treatment system.
RESULTS
First-line therapy should be selected based on nail plate involvement, with terbinafine for severe onychomycosis (>60% involvement), terbinafine or efinaconazole for moderate onychomycosis (20%-60% involvement), and efinaconazole for mild onychomycosis (<20% involvement). Comorbidities, patient preference and adherence, or nail thickness may result in the use of alternative oral or topical antifungals.
CONCLUSION
These guidelines allow healthcare providers and patients to make informed choices about preventing and treating onychomycosis.

Review
Onychomycosis is a fungal infection of the nail and is the most common nail affliction in the general population. Certain patient populations are at greater risk of infection and the prevalence of onychomycosis reported in the literature has yet to be summarized across these at-risk groups. We performed a systematic review of the literature and calculated pooled prevalence estimates of onychomycosis in at-risk patient populations. The prevalence of dermatophyte toenail onychomycosis was as follows: general population 3.22% (3.07, 3.38), children 0.14% (0.11, 0.18), the elderly 10.28% (8.63, 12.18), diabetic patients 8.75% (7.48, 10.21), psoriatic patients 10.22% (8.61, 12.09), HIV positive patients 10.40% (8.02, 13.38), dialysis patients 11.93% (7.11, 19.35) and renal transplant patients 5.17% (1.77, 14.14). Dialysis patients had the highest prevalence of onychomycosis caused by dermatophytes, elderly individuals had the highest prevalence of onychomycosis caused by yeasts (6.07%; 95% CI = 3.58, 10.11) and psoriatic patients had the highest prevalence of onychomycosis caused by non-dermatophyte moulds (2.49%; 95% CI = 1.74, 3.55). An increased prevalence of onychomycosis in certain patient populations may be attributed to impaired immunity, reduced peripheral circulation and alterations to the nail plate which render these patients more susceptible to infection.
