Nannizzia polymorpha as Rare Cause of Skin Dermatophytosis.

Nannizzia polymorpha is a dermatophyte that rarely infects humans. We describe 2 case-patients from Asia who had an inflammatory type of tinea capitis and tinea manuum caused by infection with this fungus. The diagnosis was confirmed on the basis of the morphologic and molecular characteristics of the microorganism.

Association of Alopecia Areata with Sensorineural Hearing Loss: A Systematic Review and Meta-analysis.

BACKGROUND: Immune-mediated melanocyte-related pathogenesis in alopecia areata (AA) may cause sensorineural hearing loss (SNHL). However, the relation between AA and SNHL has been unclear. Therefore, we aimed to investigate this association between AA and SNHL. METHODS: We performed a systematic review and searched MEDLINE and Embase on July 25, 2022, for cross-sectional, case-control, or cohort studies that examined the association of AA with SNHL. The Newcastle-Ottawa Scale was used to evaluate their risk of bias. A random-effects model meta-analysis was performed to obtain the mean differences in frequency-specific hearing thresholds between AA patients and age-matched healthy controls and the pooled odds ratio for SNHL in relation to AA. RESULTS: We included 5 case-control studies and 1 cohort study, with none of them rated with high risk of biases. The meta-analysis showed AA patients had significantly higher mean differences in pure-tone hearing thresholds at 4,000 Hz and 12,000-12,500 Hz. The meta-analysis also found increased odds for SNHL among patients with AA (OR: 3.18; 95% CI: 2.06-4.89; I2 = 0%). CONCLUSIONS: AA is associated with an increase of SNHL, especially at high frequencies. Otologic consultation may be indicated if AA patients present with hearing loss or tinnitus.

Interventions for bullous pemphigoid.

BACKGROUND: Bullous pemphigoid (BP) is the most common autoimmune blistering disease. Oral steroids are the standard treatment. We have updated this review, which was first published in 2002, because several new treatments have since been tried. OBJECTIVES: To assess the effects of treatments for bullous pemphigoid. SEARCH METHODS: We updated searches of the following databases to November 2021: Cochrane Skin Specialised Register, CENTRAL, MEDLINE, and Embase. We searched five trial databases to January 2022, and checked the reference lists of included studies for further references to relevant randomised controlled trials (RCTs). SELECTION CRITERIA: RCTs of treatments for immunofluorescence-confirmed bullous pemphigoid. DATA COLLECTION AND ANALYSIS: At least two review authors, working independently, evaluated the studies against the review's inclusion criteria and extracted data from included studies. Using GRADE methodology, we assessed the certainty of the evidence for each outcome in each comparison. Our primary outcomes were healing of skin lesions and mortality. MAIN RESULTS: We identified 14 RCTs (1442 participants). The main treatment modalities assessed were oral steroids, topical steroids, and the oral anti-inflammatory antibiotic doxycycline. Most studies reported mortality but adverse events and quality of life were not well reported. We decided to look at the primary outcomes 'disease control' and 'mortality'. Almost all studies investigated different comparisons; two studies were placebo-controlled. The results are therefore based on a single study for each comparison except azathioprine. Most studies involved only small numbers of participants. We assessed the risk of bias for all key outcomes as having 'some concerns' or high risk, due to missing data, inappropriate analysis, or insufficient information. Clobetasol propionate cream versus oral prednisone Compared to oral prednisone, clobetasol propionate cream applied over the whole body probably increases skin healing at day 21 (risk ratio (RR 1.08, 95% confidence interval (CI) 1.03 to 1.13; 1 study, 341 participants; moderate-certainty evidence). Skin healing at 21 days was seen in 99.8% of participants assigned to clobetasol and 92.4% of participants assigned to prednisone. Clobetasol propionate cream applied over the whole body compared to oral prednisone may reduce mortality at one year (RR 0.73, 95% CI 0.53 to 1.01; 1 study, 341 participants; low-certainty evidence). Death occurred in 26.5% (45/170) of participants assigned to clobetasol and 36.3% (62/171) of participants assigned to oral prednisone. This study did not measure quality of life. Clobetasol propionate cream may reduce risk of severe complications by day 21 compared with oral prednisone (RR 0.65, 95% CI 0.50 to 0.86; 1 study, 341 participants; low-certainty evidence). Mild clobetasol propionate cream regimen (10 to 30 g/day) versus standard clobetasol propionate cream regimen (40 g/day) A mild regimen of topical clobetasol propionate applied over the whole body compared to the standard regimen probably does not change skin healing at day 21 (RR 1.00, 95% CI 0.97 to 1.03; 1 study, 312 participants; moderate-certainty evidence). Both groups showed complete healing of lesions at day 21 in 98% participants. A mild regimen of topical clobetasol propionate applied over the whole body compared to the standard regimen may not change mortality at one year (RR 1.00, 95% CI 0.75 to 1.32; 1 study, 312 participants; low-certainty evidence), which occurred in 118/312 (37.9%) participants. This study did not measure quality of life. A mild regimen of topical clobetasol propionate applied over the whole body compared to the standard regimen may not change adverse events at one year (RR 0.94, 95% CI 0.78 to 1.14; 1 study, 309 participants; low-certainty evidence). Doxycycline versus prednisolone Compared to prednisolone (0.5 mg/kg/day), doxycycline (200 mg/day) induces less skin healing at six weeks (RR 0.81, 95% CI 0.72 to 0.92; 1 study, 213 participants; high-certainty evidence). Complete skin healing was reported in 73.8% of participants assigned to doxycycline and 91.1% assigned to prednisolone. Doxycycline compared to prednisolone probably decreases mortality at one year (RR 0.25, 95% CI 0.07 to 0.89; number needed to treat for an additional beneficial outcome (NNTB) = 14; 1 study, 234 participants; moderate-certainty evidence). Mortality occurred in 2.4% (3/132) of participants with doxycycline and 9.7% (11/121) with prednisolone. Compared to prednisolone, doxycycline improved quality of life at one year (mean difference 1.8 points lower, which is more favourable on the Dermatology Life Quality Index, 95% CI 1.02 to 2.58 lower; 1 study, 234 participants; high-certainty evidence). Doxycycline compared to prednisolone probably reduces severe or life-threatening treatment-related adverse events at one year (RR 0.59, 95% CI 0.35 to 0.99; 1 study, 234 participants; moderate-certainty evidence). Prednisone plus azathioprine versus prednisone It is unclear whether azathioprine plus prednisone compared to prednisone alone affects skin healing or mortality because there was only very low-certainty evidence from two trials (98 participants). These studies did not measure quality of life. Adverse events were reported in a total of 20/48 (42%) participants assigned to azathioprine plus prednisone and 15/44 (34%) participants assigned to prednisone. Nicotinamide plus tetracycline versus prednisone It is unclear whether nicotinamide plus tetracycline compared to prednisone affects skin healing or mortality because there was only very low-certainty evidence from one trial (18 participants). This study did not measure quality of life. Fewer adverse events were reported in the nicotinamide group. Methylprednisolone plus azathioprine versus methylprednisolone plus dapsone It is unclear whether azathioprine plus methylprednisolone compared to dapsone plus methylprednisolone affects skin healing or mortality because there was only very low-certainty evidence from one trial (54 participants). This study did not measure quality of life. A total of 18 adverse events were reported in the azathioprine group and 13 in the dapsone group. AUTHORS' CONCLUSIONS: Clobetasol propionate cream applied over the whole body is probably similarly effective as, and may cause less mortality than, oral prednisone for treating bullous pemphigoid. Lower-dose clobetasol propionate cream applied over the whole body is probably similarly effective as standard-dose clobetasol propionate cream and has similar mortality. Doxycycline is less effective but causes less mortality than prednisolone for treating bullous pemphigoid. Other treatments need further investigation.

The effects of systemic immunomodulatory treatments on COVID-19 outcomes in patients with atopic dermatitis: Results from the global SECURE-AD registry.

BACKGROUND: Limited data are available on the effects of systemic immunomodulatory treatments on COVID-19 outcomes in patients with atopic dermatitis (AD). OBJECTIVE: To investigate COVID-19 outcomes in patients with AD treated with or without systemic immunomodulatory treatments, using a global registry platform. METHODS: Clinicians were encouraged to report cases of COVID-19 in their patients with AD in the Surveillance Epidemiology of Coronavirus Under Research Exclusion for Atopic Dermatitis (SECURE-AD) registry. Data entered from 1 April 2020 to 31 October 2021 were analysed using multivariable logistic regression. The primary outcome was hospitalization from COVID-19, according to AD treatment groups. RESULTS: 442 AD patients (mean age 35.9 years, 51.8% male) from 27 countries with strongly suspected or confirmed COVID-19 were included in analyses. 428 (96.8%) patients were treated with a single systemic therapy (n = 297 [67.2%]) or topical therapy only (n = 131 [29.6%]). Most patients treated with systemic therapies received dupilumab (n = 216). Fourteen patients (3.2%) received a combination of systemic therapies. Twenty-six patients (5.9%) were hospitalized. No deaths were reported. Patients treated with topical treatments had significantly higher odds of hospitalization, compared with those treated with dupilumab monotherapy (odds ratio (OR) 4.65 [95%CI 1.71-14.78]), including after adjustment for confounding variables (adjusted OR (aOR) 4.99 [95%CI 1.4-20.84]). Combination systemic therapy which did not include systemic corticosteroids was associated with increased odds of hospitalization, compared with single agent non-steroidal immunosuppressive systemic treatment (OR 8.09 [95%CI 0.4-59.96], aOR 37.57 [95%CI 1.05-871.11]). Hospitalization was most likely in patients treated with combination systemic therapy which included systemic corticosteroids (OR 40.43 [95%CI 8.16-207.49], aOR 45.75 [95%CI 4.54-616.22]). CONCLUSIONS: Overall, the risk of COVID-19 complications appears low in patients with AD, even when treated with systemic immunomodulatory agents. Dupilumab monotherapy was associated with lower hospitalization than other therapies. Combination systemic treatment, particularly combinations including systemic corticosteroids, was associated with the highest risk of severe COVID-19.

Association of Psoriasis With Hearing Loss: A Systematic Review and Meta-Analysis.

BACKGROUND: The relation between psoriasis and hearing loss has been unclear. OBJECTIVE: To investigate the association of psoriasis with hearing loss. METHODS: We searched MEDLINE and Embase on 12th November 2022 for studies on the association between psoriasis and hearing loss. We conducted a random-effects model meta-analysis to calculate pooled mean difference (MD) in the pure tone thresholds, pooled odds ratio for sensorineural hearing loss, and pooled hazard ratio for sudden sensorineural hearing loss related to psoriasis. RESULTS: We included 12 case-control/cross-sectional and 3 cohort studies with 202,683 subjects. Psoriasis was associated with hearing loss at 500 Hz (pooled MD 2.21, 95% CI (CI) 0.13 to 4.29), 1000 Hz (pooled MD 2.97, 95% CI 1.01 to 4.93), 2000 Hz (pooled MD 5.13, 95% CI 2.45 to 7.82), 4000 Hz (pooled MD 9.3, 95% CI 5.1 to 13.51), and 6000 Hz (pooled MD 11.04, 95% CI 5.05 to 17.03). Patients with psoriasis had increased odds for sensorineural hearing loss (pooled odds ratio 3.85, 95% CI 1.07-13.9) and risk for sudden sensorineural hearing loss (pooled hazard ratio 1.45; 95% CI 1.22-1.71). CONCLUSION: Psoriasis is associated with hearing loss, especially at high frequencies.

2022 Taiwanese Dermatological Association (TDA), Taiwanese Association for Psoriasis and Skin Immunology (TAPSI), and Taiwan Society of cardiology (TSOC) joint consensus recommendations for the management of psoriatic disease with attention to cardiovascular comorbidities.

Psoriatic disease is a chronic inflammatory disorder with skin and joint manifestations. Due to the persistent inflammatory state exhibited by patients with psoriasis, multiple systemic comorbidities occur more frequently in patients with psoriasis than in the general population, and the risk of cardiovascular (CV) diseases is significantly increased. As the pathophysiology of psoriatic disease is becoming better understood, the sharing of underlying pathogenic mechanisms between psoriatic and CV diseases is becoming increasingly apparent. Consequently, careful attention to CV comorbidities that already exist or may potentially develop is needed in the management of patients with psoriasis, particularly in the screening and primary prevention of CV disease and in treatment selection due to potential drug-drug and drug-disease interactions. Furthermore, as the use of effective biologic therapy and more aggressive oral systemic treatment for psoriatic disease is increasing, consideration of the potential positive and negative effects of oral and biologic treatment on CV disease is warranted. To improve outcomes and quality of care for patients with psoriasis, the Taiwanese Dermatological Association, the Taiwanese Association for Psoriasis and Skin Immunology, and the Taiwan Society of Cardiology established a Task Force of 20 clinicians from the fields of dermatology, cardiology, and rheumatology to jointly develop consensus expert recommendations for the management of patients with psoriatic disease with attention to CV comorbidities.

Bidirectional associations between psoriasis and migraine: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES: To evaluate the association between psoriasis and migraine. PATIENTS AND METHODS: MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched for relevant observational studies from their respective inception to May 1, 2022. A random-effects model meta-analysis was performed to calculate the risk estimates quantifying the associations between psoriasis and migraine. We also performed a sensitivity analysis by including only studies with adjusted risk estimates and a subgroup analysis according to the severity of psoriasis. RESULTS: We included 9 studies with 6,742,075 participants. The meta-analysis illustrated increased odds for prevalent migraine among patients with psoriasis (pooled OR: 1.69, 95% CI: 1.26-2.28) and increased odds for prevalent psoriasis among those with migraine (OR: 1.88, 95% CI: 1.32-3.67). A subgroup analysis of cohort studies demonstrated an increasingly higher risk of incident migraine in patients with mild psoriasis and severe psoriasis (IRR being 1.37 (95% CI 1.30-1.44) and 1.55 (95% CI 1.29-1.86), respectively). CONCLUSIONS: This meta-analysis revealed significant bidirectional associations between migraine and psoriasis. Greater severity of psoriasis appears to be associated with a higher risk of developing migraine. Clinicians should evaluate symptoms of migraine in patients with psoriasis and provide proper treatments.

Associations of thiazide use with skin cancers: a systematic review and meta-analysis.

BACKGROUND: Previous findings on the associations of thiazide use with skin cancers were conflicting. This study aimed to examine the associations of individual thiazide use with skin cancer risk, differentiated by subtypes of skin cancers, geographic regions, and cumulative doses of individual thiazides. METHODS: We searched PubMed, Embase, and Cochrane Central Register of Controlled Trials for relevant studies on January 5, 2022, scanned the references of included studies, and consulted experts. We included case-control and cohort studies or randomized trials reporting the associations of individual thiazide or thiazide-like diuretics use with skin cancers. Non-melanoma skin cancer (NMSC) and melanoma were analysed separately. A random-effects model meta-analysis was conducted for pooled odds ratio (OR) and hazard ratio (HR) for skin cancers related to individual thiazide use. RESULTS: We included 15, 5, and 5 case-control or cohort studies reporting the risk for skin cancers associated with hydrochlorothiazide, bendroflumethiazide, and indapamide use, respectively, with 17,848,313 participants. The meta-analysis showed associations of hydrochlorothiazide use with increased risk of NMSC (OR 1.16, 95% CI 1.08-1.24; HR 1.26, 95% CI 1.04-1.54), squamous cell carcinoma (SCC) (OR 1.32, 95% CI 1.06-1.65; HR 1.61, 95% CI 0.97-2.67), and melanoma (OR 1.11, 95% CI 1.02-1.20; HR 1.03, 95% CI 0.93-1.14). The increased risks for SCC were associated with high cumulative doses of hydrochlorothiazide (OR 2.56, 95% CI 1.43-4.57; HR 1.20, 95% CI 1.00-1.45). Hydrochlorothiazide use was associated with different subtypes of melanoma including superficial spreading (OR 1.18, 95% CI 1.05-1.33), nodular (OR 1.23, 95% CI 1.08-1.39), and lentigo maligna melanoma (OR 1.33, 95% CI 1.08-1.65). Various cumulative doses of hydrochlorothiazide were associated with increased odds for melanoma. However, the associations of hydrochlorothiazide use with increased risk of NMSC and melanoma only appeared in non-Asian countries. No meaningful increase in the risk for skin cancers was associated with bendroflumethiazide and indapamide. CONCLUSIONS: Hydrochlorothiazide is associated with an increased risk for NMSC (especially SCC) and melanoma in non-Asian countries, whereas bendroflumethiazide and indapamide are not associated with a meaningful risk for skin cancers. Healthcare professionals and patients should be informed of the different risk profiles of skin cancers associated with different thiazides, cumulative doses, and regions.

Systematic review and critical appraisal of psoriasis clinical practice guidelines: a Global Guidelines in Dermatology Mapping Project (GUIDEMAP).

BACKGROUND: Clinical practice guidelines (CPGs) developed with rigorous methods can help optimize clinical care for patients with psoriasis. OBJECTIVES: To conduct an updated systematic review and comprehensive critical appraisal of global psoriasis CPGs. METHODS: A search of MEDLINE and Embase for psoriasis CPGs published between 1 January 2015 and 31 March 2021 was performed. Other guideline repositories were also searched for relevant CPGs. Descriptive analysis was conducted to summarize included guidelines. Three critical appraisal tools were used to assess the quality of included CPGs: the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, Lenzer et al.'s red flags, and the US Institute of Medicine's (IOM) criteria of trustworthiness. RESULTS: We included 33 psoriasis CPGs, with 25 openly accessible. Most CPGs were from high sociodemographic index countries in North America and Europe. Five CPGs received 'excellent quality' appraisals across all six AGREE II domains. Stakeholder involvement, rigour of development and applicability were the three domains with the lowest appraisal scores for AGREE II. Twenty-two CPGs raised at least one red flag indicative of potential bias. By the IOM's standards, external review of the guideline draft prior to publication and clear updating procedures were most often not addressed by guidelines, and only three CPGs were assessed as having higher overall trustworthiness. CONCLUSIONS: Most psoriasis guidelines were unable to consistently demonstrate high quality across multiple appraisal tools. The EuroGuiDerm guideline on the systemic treatment of psoriasis vulgaris was the only CPG to receive 'excellent quality' across all six AGREE II domains, to raise no Lenzer's red flags, and to have higher trustworthiness by IOM criteria.

Biologics for pediatric moderate-to-severe plaque psoriasis: a systematic review and network meta-analysis.

BACKGROUND AND OBJECTIVES: To compare the efficacy and safety of biologic treatments for moderate-to-severe pediatric psoriasis approved by the US Food and Drug Administration and European Medicines Agency. PATIENTS AND METHODS: MEDLINE, Embase, and Cochrane Central Register of Controlled Trials for relevant randomized controlled trials (RCTs) were searched for the identification of eligible RCTs until May 7, 2021. Fixed-effect frequentist network meta-analysis (NMA) was performed with the surface under the cumulative ranking curve (SUCRA) calculated for ranking. Our primary outcomes included ≥ 90 % improvement of Psoriasis Area and Severity Index score (PASI 90) at 12-16 weeks and discontinuation owing to adverse events (DAE) through the first 12-16 weeks. RESULTS: Five RCTs involving 798 pediatric psoriasis patients were included. Compared to placebo, all biologic regimens exhibited a significantly higher PASI 90 response but did not differ in the risk for DAE. Based on the SUCRA, secukinumab-low dose (SEC-L) ranked first in the achieved PASI 90 response (84.7 %), followed by ixekizumab (70.8 %). CONCLUSIONS: Among all biologic treatments, SEC-L showed the best PASI 90 response without increasing the risk for DAE. More long-term studies are warranted.

Effects of antidiabetic drugs on psoriasis: A meta-analysis.

BACKGROUND: Psoriasis, a chronic inflammatory skin disease, poses an elevated risk of developing diabetes mellitus. PURPOSE: To investigate the effects of antidiabetic medications on psoriasis. DATA SOURCES, STUDY SELECTION AND DATA EXTRACTION: We conducted a systemic review and meta-analysis and searched MEDLINE, EMBASE and CENTRAL for relevant randomized controlled trials. Our outcomes included 75% improvement in the psoriasis area and severity index from baseline (PASI 75), change in the psoriasis area and severity index (PASI) score, or change in the Dermatology Life Quality Index score under antidiabetic agents. Cochrane Collaboration's tool was used to evaluate the risk of bias of included studies. Subgroup analysis of different dosages of the antidiabetic agents was also performed. DATA SYNTHESIS: We included 10 randomized controlled studies examining the effect of antidiabetic agents. Eight studies were rated high risk of bias. Pioglitazone demonstrated significant increase in PASI 75 (risk difference = 0.42; 95% CI: 0.18-0.65) and decrease in mean PASI (mean difference = -3.82; 95% CI: -6.05-1.ㄍ59). In subgroup analysis, 30 mg pioglitazone group demonstrated a significantly higher portion of PASI 75 than 15 mg pioglitazone group (P = .003). LIMITATIONS: Some biases are reported high risk in involved articles. The main limitation of the study is in the inclusion of only glitazones. The lack of effect was seen for rosiglitazone and metformin. In the case of metformin, there was only one study available, which is also an important issue. CONCLUSIONS: The current evidence demonstrates therapeutic efficacy of pioglitazone, which may be a treatment option in patients with psoriasis and diabetes mellitus.

Association of psoriasis with colorectal cancer.

BACKGROUND: The relation between psoriasis and colorectal cancer (CRC) was largely unclear. OBJECTIVE: To investigate the association of psoriasis with CRC. METHODS: A systematic review and meta-analysis of observational studies that examined the association of psoriasis with CRC was performed. We searched MEDLINE and Embase on March 24, 2020, for relevant studies. The Newcastle-Ottawa scale was used to evaluate the risk of bias of included studies. We conducted a random-effects model meta-analysis and subgroup analysis according to sex. RESULTS: We included 9 cohort studies with 10,544,609 individuals. We found a significantly increased risk for CRC in patients with psoriasis (hazard ratio [HR], 1.16; 95% confidence interval [CI], 1.08-1.24). Subgroups analysis according to sex found significantly increased risk for CRC in female patients with psoriasis (HR, 1.41; 95% CI, 1.16-1.72) but not in male patients (HR, 1.18; 95% CI, 0.92-1.50). LIMITATIONS: No data on psoriatic arthritis. CONCLUSIONS: Patients with psoriasis have an increased risk for CRC. Gastroenterology consultation and colonoscopic examination are indicated for patients with psoriasis presenting with bowel symptoms.

Predictors of hepatitis B and C virus reactivation in patients with psoriasis treated with biologic agents: a 9-year multicenter cohort study.

BACKGROUND: The increasing use of biologics is accompanied by a risk of hepatitis B (HBV) and C virus (HCV) reactivation. OBJECTIVE: To determine the predictors of HBV and HCV reactivation in patients with psoriasis receiving biologics. METHODS: This study screened 2060 patients with psoriasis (3562 treatment episodes) who were taking biologics from 2009 to 2018. There were 359 patients with psoriasis with HBV (561 treatment episodes) and 61 with HCV infection (112 treatment episodes). RESULTS: During 8809 and 1522 person-months of follow-up, 88 treatment episodes for HBV involved HBV reactivation, and 14 episodes of HCV involved reactivation. The reactivation rate was significantly higher in treatment episodes of chronic HBV infection than in that of occult HBV (34.3% vs 3.2%, P = .001) and resolved HBV (34.3% vs 5.0%, P < .001). The multivariate analysis revealed that being hepatitis B surface antigen seropositive, being hepatitis B e-antigen seropositive, and tumor necrosis factor-α-inhibitor therapy were risk factors for HBV reactivation, whereas antiviral prophylaxis was effective in reducing the risk of HBV reactivation. No predictors were significantly associated with HCV reactivation. LIMITATIONS: Observational design and a lack of a comparison group. CONCLUSION: Patients with psoriasis on biologics have a risk of HBV and HCV reactivations, particularly those who are seropositive for hepatitis B surface antigen and hepatitis B e-antigen and undergoing tumor necrosis factor-α-inhibitor therapy.

Interventions for bacterial folliculitis and boils (furuncles and carbuncles).

BACKGROUND: Bacterial folliculitis and boils are globally prevalent bacterial infections involving inflammation of the hair follicle and the perifollicular tissue. Some folliculitis may resolve spontaneously, but others may progress to boils without treatment. Boils, also known as furuncles, involve adjacent tissue and may progress to cellulitis or lymphadenitis. A systematic review of the best evidence on the available treatments was needed. OBJECTIVES: To assess the effects of interventions (such as topical antibiotics, topical antiseptic agents, systemic antibiotics, phototherapy, and incision and drainage) for people with bacterial folliculitis and boils. SEARCH METHODS: We searched the following databases up to June 2020: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, and Embase. We also searched five trials registers up to June 2020. We checked the reference lists of included studies and relevant reviews for further relevant trials.  SELECTION CRITERIA: We included randomised controlled trials (RCTs) that assessed systemic antibiotics; topical antibiotics; topical antiseptics, such as topical benzoyl peroxide; phototherapy; and surgical interventions in participants with bacterial folliculitis or boils. Eligible comparators were active intervention, placebo, or no treatment. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. Our primary outcomes were 'clinical cure' and 'severe adverse events leading to withdrawal of treatment'; secondary outcomes were 'quality of life', 'recurrence of folliculitis or boil following completion of treatment', and 'minor adverse events not leading to withdrawal of treatment'. We used GRADE to assess the certainty of the evidence. MAIN RESULTS: We included 18 RCTs (1300 participants). The studies included more males (332) than females (221), although not all studies reported these data. Seventeen trials were conducted in hospitals, and one was conducted in clinics. The participants included both children and adults (0 to 99 years). The studies did not describe severity in detail; of the 232 participants with folliculitis, 36% were chronic. At least 61% of participants had furuncles or boils, of which at least 47% were incised. Duration of oral and topical treatments ranged from 3 days to 6 weeks, with duration of follow-up ranging from 3 days to 6 months. The study sites included Asia, Europe, and America. Only three trials reported funding, with two funded by industry. Ten studies were at high risk of 'performance bias', five at high risk of 'reporting bias', and three at high risk of 'detection bias'. We did not identify any RCTs comparing topical antibiotics against topical antiseptics, topical antibiotics against systemic antibiotics, or phototherapy against sham light. Eleven trials compared different oral antibiotics. We are uncertain as to whether cefadroxil compared to flucloxacillin (17/21 versus 18/20, risk ratio (RR) 0.90, 95% confidence interval (CI) 0.70 to 1.16; 41 participants; 1 study; 10 days of treatment) or azithromycin compared to cefaclor (8/15 versus 10/16, RR 1.01, 95% CI 0.72 to 1.40; 31 participants; 2 studies; 7 days of treatment) differed in clinical cure (both very low-certainty evidence). There may be little to no difference in clinical cure rate between cefdinir and cefalexin after 17 to 24 days (25/32 versus 32/42, RR 1.00, 95% CI 0.73 to 1.38; 74 participants; 1 study; low-certainty evidence), and there probably is little to no difference in clinical cure rate between cefditoren pivoxil and cefaclor after 7 days (24/46 versus 21/47, RR 1.17, 95% CI 0.77 to 1.78; 93 participants; 1 study; moderate-certainty evidence). For risk of severe adverse events leading to treatment withdrawal, there may be little to no difference between cefdinir versus cefalexin after 17 to 24 days (1/191 versus 1/200, RR 1.05, 95% CI 0.07 to 16.62; 391 participants; 1 study; low-certainty evidence). There may be an increased risk with cefadroxil compared with flucloxacillin after 10 days (6/327 versus 2/324, RR 2.97, 95% CI 0.60 to 14.62; 651 participants; 1 study; low-certainty evidence) and cefditoren pivoxil compared with cefaclor after 7 days (2/77 versus 0/73, RR 4.74, 95% CI 0.23 to 97.17; 150 participants; 1 study; low-certainty evidence). However, for these three comparisons the 95% CI is very wide and includes the possibility of both increased and reduced risk of events. We are uncertain whether azithromycin affects the risk of severe adverse events leading to withdrawal of treatment compared to cefaclor (274 participants; 2 studies; very low-certainty evidence) as no events occurred in either group after seven days. For risk of minor adverse events, there is probably little to no difference between the following comparisons: cefadroxil versus flucloxacillin after 10 days (91/327 versus 116/324, RR 0.78, 95% CI 0.62 to 0.98; 651 participants; 1 study; moderate-certainty evidence) or cefditoren pivoxil versus cefaclor after 7 days (8/77 versus 5/73, RR 1.52, 95% CI 0.52 to 4.42; 150 participants; 1 study; moderate-certainty evidence). We are uncertain of the effect of azithromycin versus cefaclor after seven days due to very low-certainty evidence (7/148 versus 4/126, RR 1.26, 95% CI 0.38 to 4.17; 274 participants; 2 studies). The study comparing cefdinir versus cefalexin did not report data for total minor adverse events, but both groups experienced diarrhoea, nausea, and vaginal mycosis during 17 to 24 days of treatment. Additional adverse events reported in the other included studies were vomiting, rashes, and gastrointestinal symptoms such as stomach ache, with some events leading to study withdrawal. Three included studies assessed recurrence following completion of treatment, none of which evaluated our key comparisons, and no studies assessed quality of life. AUTHORS' CONCLUSIONS: We found no RCTs regarding the efficacy and safety of topical antibiotics versus antiseptics, topical versus systemic antibiotics, or phototherapy versus sham light for treating bacterial folliculitis or boils. Comparative trials have not identified important differences in efficacy or safety outcomes between different oral antibiotics for treating bacterial folliculitis or boils. Most of the included studies assessed participants with skin and soft tissue infection which included many disease types, whilst others focused specifically on folliculitis or boils. Antibiotic sensitivity data for causative organisms were often not reported. Future trials should incorporate culture and sensitivity information and consider comparing topical antibiotic with antiseptic, and topical versus systemic antibiotics or phototherapy.

Evidence-searching capability among health care professionals: a comparative study.

BACKGROUND: Evidence-based practice is among core competencies of health care professionals (HCPs). However, the levels of evidence-searching capability may differ among various disciplines of HCPs as they receive different education and trainings for various durations in medical schools and teaching hospitals. METHODS: This study aimed to compare the evidence-searching capability among different disciplines of HCPs and identify which aspects need to be reinforced. From a teaching hospital, we recruited 80 HCPs of various disciplines and compared their evidence-searching capability by using a validated scale. To examine if sex and education levels affect evidence-searching capability, we performed a multiple linear regression analysis with collinearity diagnostics. RESULTS: Physicians and pharmacists performed significantly better than other disciplines in the seven formative assessment items and the summative item (all P < 0.05). No collinearity was detected between discipline and age nor level of education. Except for the 2nd formative assessment item (correlation coefficient 0.24 ± 0.12, P = 0.04), participant's levels of education did not affect evidence-searching capability. Age was associated with lower evidence-searching capability in five formative and the summative assessment items. CONCLUSIONS: We found a better evidence-searching capability among physicians and pharmacists than other HCPs who may require more training on evidence-searching skills. Also, evidence-searching skills training should be provided to HCPs irrespective of age and education levels.

Recommendations for psoriatic arthritis management: A joint position paper of the Taiwan Rheumatology Association and the Taiwanese Association for Psoriasis and Skin Immunology.

In Taiwan, the incidence and prevalence of psoriatic arthritis (PsA) have risen significantly in recent years. Moreover, data from the Taiwan National Health Insurance Research Database (NHIRD) show that more than 85% of PsA patients are treated with just non-steroidal anti-inflammatory drugs (NSAIDs) and/or conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs). Taiwanese clinicians have also expressed concerns regarding uncertainties in the diagnosis of PsA and the delayed, interrupted, and/or tapered use of biologics, as well as differences in therapeutic preferences between and within dermatologists and rheumatologists. To address these issues, the Taiwan Rheumatology Association and the Taiwanese Association for Psoriasis and Skin Immunology jointly convened a committee of 28 clinicians from the fields of rheumatology, dermatology, orthopedics, and rehabilitation, to develop evidence-based consensus recommendations for the practical management of PsA in Taiwan. A total of six overarching principles and 13 recommendations were developed and approved, as well as a treatment algorithm with four separate tracks for axial PsA, peripheral PsA, enthesitis, and dactylitis. Psoriasis (PsO) management was not discussed here, as the Taiwanese Dermatological Association has recently published a comprehensive consensus statement on the management of PsO. Together, these recommendations provide an up-to-date, evidence-based framework for PsA care in Taiwan.

Change in body weight and body mass index in psoriasis patients receiving biologics: A systematic review and network meta-analysis.

BACKGROUND: Previous studies have suggested that biologic therapy for psoriasis might relate to body weight gain. OBJECTIVE: To assess the changes in body weight and body mass index (BMI) in psoriasis patients after receiving various biologics. METHODS: We conducted a systematic review and network meta-analysis to evaluate the changes in body weight and BMI in psoriasis patients receiving biologics. On March 1, 2019, we searched Medline, Embase, and Cochrane Central Register of Controlled Trials for relevant studies. The Newcastle-Ottawa scale was used to assess the risk of bias. RESULTS: We included 6 studies with 862 psoriasis patients. Compared with conventional systemic treatments, treatment with tumor necrosis factor α inhibitors was associated with a significant increase in body weight (mean difference 1.40 kg, 95% confidence interval 0.88-1.93 kg) and BMI (0.39 kg/m2, 95% confidence interval 0.24-0.54 kg/m2). In contrast, no significant increase in body weight or BMI was found among patients receiving anti-interleukin (IL)-12/23 or anti-IL-17 biologics. LIMITATIONS: Only 1 study reported body weight and BMI for patients receiving the anti-IL-17 biologic. CONCLUSION: Tumor necrosis factor α inhibitor treatment appears to be associated with an increase in body weight and BMI, and treatment with anti-IL-12/23 and anti-IL-17 biologics do not. This association should be considered before initiating biologics for overweight and obese patients.

Low molecular weight heparin for prevention of microvascular occlusion in digital replantation.

BACKGROUND: The success of digital replantation is highly dependent on the patency of the repaired vessels after microvascular anastomosis. Antithrombotic agents are frequently used for preventing vascular occlusion. Low molecular weight heparin (LMWH) has been reported to be as effective as unfractionated heparin (UFH) in peripheral vascular surgery, but with fewer adverse effects. Its benefit in microvascular surgery such as digital replantation is unclear. This is an update of the review first published in 2013. OBJECTIVES: To assess if treatment with subcutaneous LMWH improves the salvage rate of the digits in patients with digital replantation after traumatic amputation. SEARCH METHODS: The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, AMED and CINAHL databases, and the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers, to 17 March 2020. The authors searched PubMed, China National Knowledge Infrastructure (CNKI) and Chinese Electronic Periodical Services (CEPS) on 17 March 2020 and sought additional trials from reference lists of relevant publications. SELECTION CRITERIA: We included randomised or quasi-randomised controlled trials comparing treatment with LMWH versus any other treatment in participants who received digital replantation following traumatic digital amputation. DATA COLLECTION AND ANALYSIS: Two review authors (PL, CC) independently extracted data and assessed the risk of bias of the included trials using Cochrane's 'Risk of bias' tool. Disagreements were resolved by discussion. We assessed the certainty of evidence using the GRADE approach. MAIN RESULTS: We included two new randomised trials in this update, bringing the total number of included trials to four. They included a total of 258 participants, with at least 273 digits, from hospitals in China. Three studies compared LMWH versus UFH, and one compared LMWH versus no LMWH. The mean age of participants ranged from 24.5 to 37.6 years. In the studies reporting the sex of participants, there were a total of 145 men and 59 women. The certainty of the evidence was downgraded to low or very low because all studies were at high risk of performance or reporting bias (or both) and there was imprecision in the results due to the small numbers of participants. The three studies comparing LMWH versus UFH reported the success rate of replantation using different units of analysis (participant or digit), so we were unable to combine data from all three studies (one study reported results for both participants and digits). No evidence of a benefit in success of replantation was seen in the LMWH group when compared with UFH, regardless of whether the outcomes were reported by number of participants (risk ratio (RR) 0.98, 95% confidence interval (CI) 0.87 to 1.10; 130 participants, 2 studies; very low-certainty evidence); or by number of digits (RR 0.97, 95% CI 0.90 to 1.04; 200 digits, 2 studies; low-certainty evidence). No studies reported the incidence of compromised microcirculation requiring surgical or non-surgical therapy, or any systemic/other causes of microvascular insufficiency. There was no evidence of a clear difference between the LMWH and UFH groups in occurrence of arterial occlusion (RR 1.08, 95% CI 0.16 to 7.10; 54 participants, 1 study; very low-certainty evidence) or venous occlusion (RR 0.81, 95% CI 0.20 to 3.27; 54 participants, 1 study; very low-certainty evidence). Two studies reported adverse effects. The LMWH and UFH groups showed no evidence of a difference in wound bleeding (RR 0.53, 95% CI 0.23 to 1.23; 130 participants, 2 studies; low-certainty evidence), haematuria (RR 0.43, 95% CI 0.09 to 2.11; 130 participants, 2 studies; very low-certainty evidence), ecchymoses (RR 0.82, 95% CI 0.21 to 3.19; 130 participants, 2 studies; very low-certainty evidence), epistaxis (RR 0.27, 95% CI 0.03 to 2.32; 130 participants, 2 studies; very low-certainty evidence), gingival bleeding (RR 0.18, 95% CI 0.02 to 1.43; 130 participants, 2 studies; very low-certainty evidence), and faecal occult blood (RR 0.27, 95% CI 0.03 to 2.31; 130 participants, 2 studies; very low-certainty evidence). We could not pool data on coagulation abnormalities as varying definitions and tests were used in the three studies. One study compared LMWH versus no LMWH. The success rate of replantation, when analysed by digits, was reported as 91.2% success in the LMWH group and 82.1% in the control group (RR 1.11, 95% CI 0.93 to 1.33; 73 digits, 1 study; very low-certainty evidence). Compromised microcirculation requiring surgical re-exploration, analysed by digits, was 11.8% in the LMWH group and 17.9% in the control group (RR 0.86, 95% CI 0.21 to 3.58; 73 digits, 1 study; very low-certainty evidence). Compromised microcirculation requiring incision occurred in five out of 34 digits (14.7%) in the LMWH group and eight out of 39 digits (20.5%) in the control group (RR 0.72, 95% CI 0.26 to 1.98; 73 digits; very low-certainty evidence). Microvascular insufficiency due to arterial occlusion, analysed by digits, was 11.8% in the LMWH group and 17.9% in the control group (RR 0.66, 95% CI 0.21 to 2.05; 73 digits, 1 study; very low-certainty evidence), and venous occlusion was 14.7% in the LMWH group and 20.5% in the control (RR 0.72, 95% CI 0.26 to 1.98; 73 digits, 1 study; very low-certainty evidence). The study did not report complications or adverse effects. AUTHORS' CONCLUSIONS: There is currently low to very low-certainty evidence, based on four RCTs, suggesting no evidence of a benefit from LMWH when compared to UFH on the success rates of replantation or affect microvascular insufficiency due to vessel occlusion (analysed by digit or participant). LMWH had similar success rates of replantation; and the incidence rate of venous and arterial microvascular insufficiency showed no evidence of a difference between groups when LMWH was compared to no LMWH (analysed by digit). Similar rates of complications and adverse effects were seen between UFH and LMWH. There was insufficient evidence to draw conclusions on any effect on coagulation when comparing LMWH to UFH or no LMWH. The certainty of the evidence was downgraded due to performance and reporting bias, as well as imprecision in the results. Further adequately powered studies are warranted to provide high-certainty evidence.

Performance of Bioelectrical Impedance Analysis in the Estimation of Bone Mineral Content in Healthy Children Aged 6-12 Years.

BACKGROUND: Bioelectrical impedance analysis (BIA) is a widely available tool which provides mineral estimate. However, BIA is not currently recognized as a bone mineral measuring method. This study aimed to explore the ability of BIA to predict bone mineral content (BMC) in children, using dual-energy X-ray absorptiometry as a gold standard. METHODS: Healthy children aged 6-12 years (n = 176) were recruited for BIA and dual-energy X-ray absorptiometry measurements. Predictive models were generated using basic indices (age, height, weight, waist circumference, hip circumference, etc.) and BIA parameters (minerals, fat mass, and fat free mass). RESULTS: The root-mean-square deviation and R2 for the total BMC predictive model were 0.089 kg and 0.926, respectively using height and weight as predictors whereas 0.113 kg and 0.886, respectively using minerals by BIA. The root-mean-square deviation and R2 for the subtotal BMC predictive model were 0.080 kg and 0.935, respectively using height and weight as predictors whereas 0.098 kg and 0.906, respectively using minerals by BIA. The best predictive models included basic indices and BIA parameters as predictors, but they had only slightly better performance over simple models. CONCLUSIONS: Mineral content by BIA was good predictor of total and subtotal BMC in healthy children but with similar overall model performance compared to basic indices. More complex models combined all the predictive variables gave better prediction power, but of little improvement to these simple models. The BIA instrument does not appear to be useful in estimating BMC in healthy children as basic indices are more widely available measures but provide comparable performance. Future studies are needed to determine the clinical usefulness of the more complex prediction model in children with disease or children in other subgroups.

Associations of HLA genotypes with antithyroid drug-induced agranulocytosis: A systematic review and meta-analysis of pharmacogenomics studies.

AIMS: Antithyroid drug (ATD)-induced agranulocytosis is a life-threatening adverse drug reaction. Previous studies suggested that HLA genotypes may play an important role in ATD-induced agranulocytosis. To examine the associations between HLA genotypes and ATD-induced agranulocytosis, we conducted a systematic review and meta-analysis of pharmacogenomics studies. METHODS: We searched the MEDLINE, Embase and CENTRAL databases on 16 June 2018 for case-control studies on the associations between HLA genotypes with ATD-induced agranulocytosis. The Newcastle-Ottawa scale was used to evaluate the risk of bias of included studies. We conducted random-effects model meta-analysis to obtain pooled odds ratios (ORs) with 95% confidence intervals (CIs) to determine the associations between HLA genotypes and ATD-induced agranulocytosis. RESULTS: We included 5 studies with 142 ATD-induced agranulocytosis cases, 1529 matched ATD-tolerant controls and 5945 healthy controls. The risk of bias of included studies was generally low. ATD-induced agranulocytosis was associated with HLA-B*27:05 (OR 10.97; 95% CI 0.75-159.99), HLA-B*38:02 (OR 19.85; 95% CI 7.94-49.57) and HLA-DRB1*08:03 (OR 5.29; 95% CI 3.44-8.14). After excluding propylthiouracil, the associations of ATD-induced agranulocytosis with HLA-B*27:05 and HLA-B*38:02 were strengthened (OR being 20.61 (95% CI 5.21-81.58) and 40.59 (95% CI 13.24-124.47), respectively). The associations of ATD-induced agranulocytosis with HLA-B*27:05, HLA-B*38:02 and HLA-DRB1*08:03 remained significant when compared to population controls (OR being 7.37 (95% CI 3.86-14.07), 36.43 (95% CI 12.80-103.70) and 5.42 (95% CI 2.36-12.47), respectively). HLA-B*27:05, HLA-B*38:02, and HLA-DRB1*08:03 alleles were associated with ATD-induced agranulocytosis, especially in carbimazole/methimazole-induced agranulocytosis. CONCLUSIONS: HLA-B*27:05, HLA-B*38:02 and HLA-DRB1*08:03 alleles were associated with ATD-induced agranulocytosis, especially in carbimazole/methimazole-induced agranulocytosis.
