Abstract
PURPOSE Streptococcus dysgalactiae subsp. equisimilis (SDSE) has increasingly been recognised as a significant pathogen that causes a myriad of infections, ranging from cellulitis to invasive infections, including bacteraemia and even toxic shock syndrome. The aim of this study was to examine the epidemiology and disease manifestations of bacteraemia caused by SDSE. METHODS We retrospectively reviewed cases of SDSE bacteraemia in adults aged ≥ 18 years admitted to four public hospitals in Western Sydney, Australia, between January 2015 and December 2020. We reviewed demographics, comorbidities, disease manifestations, management, and outcomes. RESULTS There were 108 patients with SDSE bacteraemia over a six-year period. The median age of individuals with SDSE bacteraemia was 70 years (interquartile range, IQR, 58-85 years). Cardiovascular disease (46%), chronic skin conditions (44%) and diabetes (37%) were the most common comorbidities. Ten patients (9%) with SDSE bacteraemia had healthcare-acquired infections. Skin and skin structure infections (SSTIs) were the most common presentations (59%), while bone and joint infections (BJIs) represented 13% of the cases. Twenty patients (19%) had septic shock on presentation. Fifteen patients (14%) were prescribed clindamycin, while one patient received intravenous immunoglobulin (IVIg). Infective endocarditis (IE) was present in 3% of patients; however, only 44% of the total patients had an echocardiogram. The 30-day mortality rate was 13%, but it was greater in those aged > 75 years (21%). The average length of hospital stay for patients who survived was 15 days, and the average duration of intravenous therapy was 12 days. CONCLUSION SDSE bacteraemia is typically a community-onset infection with a fifth of patients in our cohort presenting with septic shock. Though complications such as BJI (13%) and IE (3%) are infrequent, 30-day mortality is high at 21% in those aged > 75 years.

Abstract
OBJECTIVES To evaluate the efficacy of topical miconazole or amorolfine compared to placebo for mild to moderately severe onychomycosis. DESIGN Randomised, double-blind, placebo-controlled trial, with computer-generated treatment allocation at a 1:1:1 ratio. SETTING Primary care, recruitment from February 2020 to August 2022. PARTICIPANTS 193 patients with suspected mild to moderately severe onychomycosis were recruited via general practices and from the general public, 111 of whom met the study criteria. The mean age of participants was 51 (SD 13.1), 51% were female and onychomycosis was moderately severe (mean OSI 12.1 (SD 8.0)). INTERVENTIONS Once-daily miconazole 20 mg/g or once-weekly amorolfine 5% nail lacquer solution was compared with placebo (denatonium benzoate solution). MAIN OUTCOME MEASURES Complete, clinical and mycological cure at 6 months. Secondary outcomes were clinical improvement, symptom burden, quality of life, adverse effects, compliance, patient-perceived improvement and treatment acceptability. RESULTS Based on intention-to-treat analysis, none of the participants receiving miconazole or amorolfine reached complete cure compared with two in the placebo group (OR not estimable (n.e.), p=0.493 and OR n.e., p=0.240, respectively). There was no evidence of a significant difference between groups regarding clinical cure (OR n.e., p=0.493 and OR 0.47, 95% CI 0.04 to 5.45, p=0.615) while miconazole and amorolfine were less effective than placebo at reaching both mycological cure (OR 0.25, 95% CI 0.06 to 0.98, p=0.037 and OR 0.23, 95% CI 0.06 to 0.92, p=0.029, respectively) and clinical improvement (OR 0.26, 95% CI 0.08 to 0.91, p=0.028 and OR 0.25, 95% CI 0.07 to 0.85, p=0.021, respectively). There was no evidence of a significant difference in disease burden, quality of life, adverse reactions, compliance, patient-perceived improvement or treatment acceptability. CONCLUSIONS Topical miconazole and amorolfine were not effective in achieving a complete, clinical or mycological cure of mild to moderately severe onychomycosis, nor did they significantly alleviate the severity or symptom burden. These treatments should, therefore, not be advised as monotherapy to treat onychomycosis. TRIAL REGISTRATION NUMBER WHO ICTRP NL8193.

Abstract
INTRODUCTION Diabetic foot ulcers are feared complications of diabetes mellitus (DM), requiring extensive treatment and hospital admissions, ultimately leading to amputation and increased mortality. Different factors contribute to the development of foot ulcers and related complications. Onychomycosis, being more prevalent in patients with diabetes, could be an important risk factor for developing ulcers and related infections. However, the association between onychomycosis and diabetic complications has not been well studied in primary care. RESEARCH DESIGN AND METHODS To determine the impact of onychomycosis on ulcer development and related complications in patients with diabetes in primary care, a longitudinal cohort study was carried out using routine care data from the Extramural Leiden University Medical Center Academic Network. Survival analyses were performed through Cox proportional hazards models with time-dependent covariates. RESULTS Data from 48 212 patients with a mean age of 58 at diagnosis of DM, predominantly type 2 (87.8%), were analysed over a median follow-up of 10.3 years. 5.7% of patients developed an ulcer. Onychomycosis significantly increased the risk of ulcer development (HR 1.37, 95% CI 1.13 to 1.66), not affected by antimycotic treatment, nor after adjusting for confounders (HR 1.23, 95% CI 1.01 to 1.49). The same was found for surgical interventions (HR 1.54, 95% CI 1.35 to 1.75) and skin infections (HR 1.48, CI 95% 1.28 to 1.72), again not affected by treatment and significant after adjusting for confounders (HR 1.32, 95% CI 1.16 to 1.51 and HR 1.27, 95% CI 1.10 to 1.48, respectively). CONCLUSIONS Onychomycosis significantly increased the risk of ulcer development in patients with DM in primary care, independently of other risk factors. In addition, onychomycosis increased the risk of surgeries and infectious complications. These results underscore the importance of giving sufficient attention to onychomycosis in primary care and corresponding guidelines. Early identification of onychomycosis during screening and routine care provides a good opportunity for timely recognition of increased ulcer risk.

Abstract
Onychomycosis is the most prevalent nail disease and is frequently encountered in clinical practice. Despite having multiple therapeutic options, of which systemic antifungals are the most effective, treatment is not always mandatory in all patients. Especially when considering systemic treatment, the risk of adverse reactions may outweigh the potential benefits of treatment. In this case report, we present a clinical case of a 49-year-old male patient with a blank past medical history who experienced a severe drug eruption from terbinafine prescribed for mild onychomycosis that required discontinuation of terbinafine, additional evaluation, and treatment of this adverse reaction.

Abstract
Lymphoedema is caused by an imbalance between fluid production and transport by the lymphatic system. This imbalance can be either caused by reduced transport capacity of the lymphatic system or too much fluid production and leads to swelling associated with tissue changes (skin thickening, fat deposition). Its main common complication is the increased risk of developing cellulitis/erysipelas in the affected area, which can worsen the lymphatic function and can be the cause of raised morbidity of the patient if not treated correctly/urgently. The term primary lymphoedema covers a group of rare conditions caused by abnormal functioning and/or development of the lymphatic system. It covers a highly heterogeneous group of conditions. An accurate diagnosis of primary lymphoedema is crucial for the implementation of an optimal treatment plan and management, as well as to reduce the risk of worsening. Patient care is diverse across Europe, and national specialised centres and networks are not available everywhere. The European Reference Network on Rare Multisystemic Vascular Diseases (VASCERN) gathers the best expertise in Europe and provide accessible cross-border healthcare to patients with rare vascular diseases. There are six different working groups in VASCERN, which focus on arterial diseases, hereditary haemorrhagic telangiectasia, neurovascular diseases, lymphoedema and vascular anomalies. The working group Paediatric and Primary Lymphedema (PPL WG) gathers and shares knowledge and expertise in the diagnosis and management of adults and children with primary and paediatric lymphoedema. The members of PPL WG have worked together to produce this opinion statement reflecting strategies on how to approach patients with primary and paediatric lymphoedema. The objective of this patient pathway is to improve patient care by reducing the time to diagnosis, define the best management and follow-up strategies and avoid overuse of resources. Therefore, the patient pathway describes the clinical evaluation and investigations that lead to a clinical diagnosis, the genetic testing, differential diagnosis, the management and treatment options and the patient follow up at expert and local centres. Also, the importance of the patient group participation in the PPL WG is discussed.

Abstract
Background and objectives: The objective of this study is to elucidate peripheral occlusion artery disease (PAOD) as a risk factor for cellulitis. Materials and Methods: This is a retrospective population-based cohort study. The database is the Longitudinal Health Insurance Database, which covers two million beneficiaries from the entire population of the 2010 registry for beneficiaries in Taiwan. The PAOD group is composed of patients who were newly diagnosed with PAOD from 2001 to 2014. The non-PAOD group is composed of patients who were never diagnosed with PAOD from 2001 to 2015. All patients were followed until the onset of cellulitis, death, or until the end of 2015. Results: Finally, 29,830 patients who were newly diagnosed with PAOD were included in the PAOD group, and 29,830 patients who were never diagnosed with PAOD were included in the non-PAOD group. The incidence densities (ID) of cellulitis were 26.05 (95% CI = 25.31-26.80) patients per 1000 person-years in the PAOD group and 49.10 (95% CI = 48.04-50.19) in the non-PAOD group. The PAOD group had an increased risk of cellulitis (adjusted HR = 1.94, 95% CI = 1.87-2.01) compared to the non-PAOD group. Conclusions: Patients with PAOD were associated with a higher risk of subsequent cellulitis compared to patients without PAOD.

Abstract
Cellulitis is a bacterial infection of the dermis and subcutaneous tissues occupying a large proportion of hospital beds. This study was conducted for analysis of patients with cellulitis according to their demographics and clinical presentation and to examine their comorbidities, complications, and its management. This observational cross-sectional study was conducted in the Department of Surgery at Santosh Medical College and Hospitals involving a total of 60 cases having cellulitis and other soft tissue infections of lower limb. Analysis of their demographic profile, management, and complications was done. Cellulitis is seen commonly in males, 46 (76.6%). The mean age of patients affected by cellulitis in the study was 36.4 ± 1.23 years. The most common site affected is leg involving more people in field jobs. The most common risk factor was trauma in 46.6%, and other factors were diabetes mellitus and smoking, while abscess formation was the most common complication observed in 36.6% of cases. A total of 56.6% cases were managed conservatively, while 43.3% cases required surgical intervention. Mean hospital stay in this study was 5.02 ± 0.23 days. It was concluded that cellulitis is subcutaneous, spreading bacterial infection is more common in males, and its incidence is highest in working age group population. Lower limb is commonly involved. Trauma, smoking, and diabetes are significant risk factors for development of cellulitis. Abscess is the most common complication. About 50% patients with cellulitis can be managed conservatively and the rest require surgical intervention.

Abstract
BACKGROUND Streptococcus dysgalactiae subspecies equisimilis is a human pathogen causing severe invasive infections. Detailed information on S. dysgalactiae subsp. equisimilis bacteremia and especially of predisposing factors are lacking. The purpose of the study is to investigate the risk factors of S. dysgalactiae subsp. equisimilis bacteremia compared to the general population in Finland. METHODS We retrospectively reviewed all patients older than 18 years with S. dysgalactiae subsp. equisimilis bacteremia in the Pirkanmaa health district from August 2015 to July 2018. The risk factors for S. dysgalactiae subsp. equisimilis bacteremia were investigated with respect to the normal population in Finland using the Finhealth study data provided by the Finnish institute for health and welfare. The study group was matched with the Finhealth study by age and sex. RESULTS Altogether 230 cases of S. dysgalactiae subsp. equisimilis bacteremia were detected. The medical records of 217 episodes of S. dysgalactiae subsp. equisimilis bacteremia (involving 211 patients) were available for analysis. Obesity was a statistically significant risk factor for S. dysgalactiae subsp. equisimilis bacteremia (Odds Ratio 2.96 [95% CI 2.22-3.96]). Diabetes and coronary artery disease were also associated with an increased risk of S. dysgalactiae subsp. equisimilis bacteremia (OR 4.82 [95% CI 3.62-6.42]) and (OR 3.03 [95% CI 2.18-4.19]). CONCLUSIONS We found obesity, diabetes, and coronary artery disease to be associated with an increased risk for S. dysgalactiae subsp. equisimilis bacteremia. These results provide an increased understanding of risk factors for S. dysgalactiae subsp. equisimilis bacteremia.

Abstract
Recurrent cellulitis following successful treatment is common and prevention should be a major component in the management of cellulitis. Conditions that increase the risk of recurrence include chronic edema, venous disease, dermatomycosis and obesity. These risk factors should be actively managed as further episodes of cellulitis increases the risk of recurrence. The role of non-antibiotic measures is important and should be first-line in prevention. Antibiotic prophylaxis is effective, but its role is limited to non-purulent cellulitis where risk factors are appropriately managed.

Abstract
Background Cellulitis is an infection most commonly caused by bacteria and successfully treated with antibiotics. However, certain patient populations, especially the immunocompromised, are at risk for fungal cellulitis, which can be misidentified as bacterial cellulitis and contribute to significant morbidity and mortality. Case presentations We describe three cases of opportunistic fungal cellulitis in immunosuppressed patients that were initially mistaken for bacterial infections refractory to antibiotic therapy. However, atypical features of cellulitis ultimately prompted further diagnostics to identify fungal cellulitis and allow initiation of appropriate antifungals. We discuss: (1) a 52-year-old male immunosuppressed hematopoietic cell transplant recipient with Fusarium solani cellulitis on his right lower extremity that was treated with amphotericin B and voriconazole with full resolution of the cellulitis; (2) a 70-year-old male lung transplant recipient with Fusarium solani cellulitis on his left lower extremity that ultimately progressed despite antifungals; and (3) a 68-year-old male with a history of kidney transplantation with suspected Purpureocillium lilacinum cellulitis on his left lower extremity ultimately treated with posaconazole with resolution of the skin lesions. Conclusions Fusarium solani and Purpureocillium lilacinum are important pathogens causing opportunistic fungal cellulitis. These cases remind providers to be vigilant for fungal cellulitis when skin and soft tissue infection does not adequately respond to antibiotics and atypical features of cellulitis are present.

Lasers Surg Med 2022; 54:861-874.

Abstract
Purpose Conventional oral antifungal therapies for onychomycosis (OM) often do not achieve complete cure and may be associated with adverse effects, medical interactions, and compliance issues restricting their use in a large group of patients. Topical treatment can bypass the systemic side effects but is limited by the physical barrier of the nail plate. Ablative fractional laser (AFL) treatment can be used to improve the penetration of topical drugs into the nail. This study visualized the effects of laser ablation of nail tissue and assessed their impact on the biodistribution of a fluorescent dye in healthy and fungal nail tissue. Methods For the qualitative assessment of CO2 AFL effects on healthy nail tissue, scanning electron microscopy (SEM), coherent anti‐Stokes Raman scattering microscopy (CARS‐M), and widefield fluorescence microscopy (WFM) were used. To quantitate the effect of laser‐pretreatment on the delivery of a fluorescent dye, ATTO‐647N, into healthy and fungal nail tissue, ablation depth, nail plate thickness, and ATTO‐647N fluorescence intensity in three nail plate layers were measured using WFM. A total of 30 nail clippings (healthy n = 18, fungal n = 12) were collected. An aqueous ATTO‐647N solution was directly applied to the dorsal surface of 24 nail samples (healthy n = 12, fungal n = 12) and incubated for 4 hours, of which half (healthy n = 6, fungal n = 6) had been pretreated with AFL (30 mJ/mb, 15% density, 300 Hz, pulse duration <1 ms). Results Imaging revealed a three‐layered nail structure, an AFL‐induced porous ablation crater, and changes in autofluorescence. While intact fungal samples showed a 106% higher ATTO‐647N signal intensity than healthy controls, microporation led to a significantly increased fluorophore permeation in all samples (p < 0.0001). AFL processing of nail tissue enhanced topical delivery of ATTO‐647N in all layers, (average increase: healthy +108%, fungal +33%), most pronounced in the top nail layer (healthy +122%, fungal +68%). While proportionally deeper ablation craters correlated moderately with higher fluorescence intensities in healthy nail tissue, fungal samples showed no significant relationship. Conclusion Fractional CO2 laser microporation is a simple way of enhancing the passive delivery of topically applied ATTO‐647N. Although the impaired nail plate barrier in OM leads to greater diffusion of the aqueous solution, AFL can increase the permeability of both structurally deficient and intact nails.

Abstract
GENERAL PURPOSE To review an approach to diabetic foot infections (DFIs), including acute osteomyelitis, while also discussing current practices and the challenges in diagnosis and management. TARGET AUDIENCE This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES After participating in this educational activity, the participant will1. Identify the risk factors for developing DFIs.2. Outline diagnostic techniques for assessing DFIs.3. Select the assessment techniques that support a diagnosis of osteomyelitis.4. Choose the appropriate pharmacologic and nonpharmacologic treatment options for patients who have DFIs. ABSTRACT Diabetic foot ulcers result from a combination of peripheral neuropathy, vascular compromise, and repetitive trauma. Approximately 50% of individuals with diabetic foot ulcers will develop a diabetic foot infection (DFI), and 20% of individuals with a DFI will develop osteomyelitis. Herein, the authors review an approach to DFIs including acute osteomyelitis and discuss current practices and challenges in diagnosis and management.The diagnosis of a skin and soft tissue DFI is based on clinical criteria. A bone biopsy is considered the criterion standard for diagnosis of osteomyelitis; however, biopsy is not always feasible or available. Consequently, diagnosis can be made using a combination of clinical, biochemical, and radiographic findings. X-ray is the recommended imaging modality for initial evaluation; however, because of its lower relative sensitivity, advanced imaging may be used when clinical suspicion remains after negative initial testing.The microbiology of skin and soft tissue DFIs and osteomyelitis is similar. Staphylococcus aureus and other Gram-positive cocci are the most common pathogens identified. Deep cultures are preferred in both DFI and osteomyelitis to identify the etiologic pathogens implicated for targeted antimicrobial therapy. Management also requires a multidisciplinary approach. Surgical debridement in those with deep or severe infections is necessary, and surgical resection of infected bone is curative in cases of osteomyelitis. Finally, appropriate wound care is critical, and management of predisposing factors, such as peripheral neuropathy, peripheral arterial disease, tinea, and edema, aids in recovery and prevention.

Abstract
The recent pandemic Sars-CoV2 infection and studies on previous influenza epidemic have drawn attention to the association between the obesity and infectious diseases susceptibility and worse outcome. Metabolic complications, nutritional aspects, physical inactivity, and a chronic unbalance in the hormonal and adipocytokine microenvironment are major determinants in the severity of viral infections in obesity. By these pleiotropic mechanisms obesity impairs immune surveillance and the higher leptin concentrations produced by adipose tissue and that characterize obesity substantially contribute to such immune response dysregulation. Indeed, leptin not only controls energy balance and body weight, but also plays a regulatory role in the interplay between energy metabolism and immune system. Since leptin receptor is expressed throughout the immune system, leptin may exert effects on cells of both innate and adaptive immune system. Chronic inflammatory states due to metabolic (i.e., obesity) as well as infectious diseases increase leptin concentrations and consequently lead to leptin resistance further fueling inflammation. Multiple factors, including inflammation and ER stress, contribute to leptin resistance. Thus, if leptin is recognized as one of the adipokines responsible for the low grade inflammation found in obesity, on the other hand, impairments of leptin signaling due to leptin resistance appear to blunt the immunologic effects of leptin and possibly contribute to impaired vaccine-induced immune responses. However, many aspects concerning leptin interactions with inflammation and immune system as well as the therapeutical approaches to overcome leptin resistance and reduced vaccine effectiveness in obesity remain a challenge for future research.

Abstract
OBJECTIVE Cellulite infection is a non-necrotizing inflammation of the skin and subcutaneous tissue and is one of the most common reasons for admission to hospital. This retrospective study aimed to investigate the Neutrophil to Lymphocyte Ratio (NLR), Platelet to Lymphocyte Ratio (PLR), and Lymphocyte to Monocyte Ratio (LMR) in patients with cellulitis. METHODS In our study, we retrospectively analyzed 96 patients with cellulitis and 98 age- and sex-matched healthy controls. The study and control groups were compared regarding NLR, PLR, and LMR.0.001). When patients with cellulitis were divided into two groups, i.e., ≥65 years and <65 years, a statistically significant difference was noted in the NLR and LMR values (p < 0.05). In the ROC curve analysis, NLR had the highest discriminative power in distinguishing between cellulitis and healthy controls (AUC = 0.950, 95% CI: 0.920-0.979, p < 0.001; 91.6% sensitivity and 89.8% specificity). CONCLUSION NLR was significantly higher in differentiating cellulite and in patients older than 65 years. Larger, prospective studies are required to determine its usefulness in assessing differential diagnosis and prognosis in cellulitis patients.

Abstract
BACKGROUND AND OBJECTIVES Mycological diagnosis of onychomycosis is based on direct microscopy using external fluorophores to visualize fungal tissue in nail samples and agar culture. Ultraviolet fluorescence excitation imaging (u-FEI) has shown potential in monitoring biological processes by exploiting variations in autofluorescence. This study aimed at assessing the potential of a handheld u-FEI system as a practical screening tool for fungal nail infections. STUDY DESIGN/MATERIALS AND METHODS Ninety samples from 29 patients with microscopy-confirmed fungal infection and 10 control samples from healthy participants were collected (n = 100). Using a prototype u-FEI system (single bandpass 25 mm filter with a central pass wavelength of 340 nm and a bandwidth of 12 nm, 295 nm excitation flash, resolution of 640 × 480), images of all samples were acquired under standardized conditions. Average and maximum fluorescence intensity image values in arbitrary units (AU) of manually delineated regions of interests were quantitated and statistically assessed for significant differences between healthy and mycotic samples. RESULTS UV-images clearly depicted all 100 nail samples, with a visibly stronger signal in infected samples. Statistically significant differences (P < 0.05) in signal intensity between mycotic samples and healthy controls were observed for maximum and average fluorescence values. Mean fluorescence values of onychomycotic samples showed 23.9% higher maximum (mycotic: 34.9 AU [standard deviation [SD] 4.7]; healthy: 28.2 AU [SD 1.9]) and 10.2% higher average (mycotic: 27.6 AU [SD 2.0]; healthy: 25.0 AU [SD 0.7]) signal intensity values. Receiver operating characteristic curves demonstrated excellent discriminatory ability (area under the curve > 0.9). Analysis of fluorescence measurements of the reference standard demonstrated very low variation (coefficient of variation = 0.62%) CONCLUSION: Quantitation of u-FEI intensities enables differentiation between healthy and mycotic nail samples, constituting a potential point-of-care tool for cost-effective screening for onychomycosis at a primary care level.

Abstract
INTRODUCTION Lower limb cellulitis is a common superficial skin infection that leads to morbidity and mortality. Cellulitis risk factors have been well studied in many countries, but to date, not in Malaysia. Geographical and climate variables may affect risk factors. Early identification of the preventable risk factors is vital to prevent cellulitis and improve holistic patient care. OBJECTIVE To determine the risk factors of lower limb cellulitis amongst hospitalized patients at a tertiary center. METHODS A prospective case-control study of hospitalized patients with a clinical diagnosis of lower limb cellulitis was conducted at UKM Medical Centre, January-August 2015. Each patient was compared to two age and gender-matched control patients. All patients were interviewed and examined for risk factors of cellulitis. RESULTS A total of 96 cellulitis patients and 192 controls participated in this study. The cellulitis patients included 61 males and 35 females with a mean age of 62.07±15.43 years. The majority of patients were experiencing their first episode of cellulitis. Multivariate analysis showed a previous history of cellulitis (OR 25.53; 95% CI 4.73-137.79), sole anomalies (OR 16.32; 95% CI 6.65-40.06), ulceration (OR 14.86; 95% CI 1.00-219.39), venous insufficiency (OR 10.46 95% CI 1.98-55.22), interdigital intertrigo (OR 8.86; 95% CI 3.33-23.56), eczema (OR 5.74; 95% CI 0.96.-34.21), and limb edema (OR 3.95; 95% CI 1.82-8.59) were the significant risk factors for lower limb cellulitis. CONCLUSION Previous cellulitis and factors causing skin barrier disruption such as sole anomalies, ulceration, venous insufficiency, eczema, intertrigo, and limb edema were the risk factors for lower limb cellulitis. Physician awareness, early detection, and treatment of these factors at the primary care level may prevent hospital admission and morbidity associated with cellulitis.

Abstract
Background Onychomycosis (OM) is a common fungal infection of the nail unit with a worldwide prevalence of 5%. Though apparently a benign and innocuous entity, it carries significant psychosocial morbidity. The Dermatology Life Quality Index (DLQI) is based on a simple practical questionnaire that considers multiple psychological and social domains. Its utility in OM by far remains unexplored. Objective To determine the DLQI in patients suffering from OM. Methods The DLQI questionnaire was answered by 100 patients with an established diagnosis of OM. Results The mean DLQI of our study subjects was 6.1 ± 3.3. Most patients (46%) belonged to the DLQI 2 group (moderate effect). Among these, most patients reported disease duration of 1-5 years (50%). Among patients responding to DLQI 3 (very large effect), a higher significant proportion were females (66.7%). The most inconvenient domain was seeking treatment for OM and social embarrassment due to the disease. Conclusion As DLQI is an easy scoring method, it can be used for assessing quality of health in OM. OM causes moderate effect on quality of life (mostly DLQI 2), thereby making its treatment mandatory.

Abstract
Objective This was a 5 year retrospective study of patients’ hospital records to find out how patients with cellulitis are managed and the care provided by nurses to these patients in some hospitals in Fako, Cameroon. Results Of the 236 cases of cellulitis identified from a study of hospital records, 202 were included in the study. Most of the participants (55%) were female and the mean (SD) age was 43 (1.1) years. Cellulitis accounted for 2.3% of admissions in this study. The predisposing factors identified were; the presence of trauma (60.5%), HIV infection (18.6%), alcohol consumption (8.4%) and tobacco use (4.8%). Commonly recorded complications were necrosis (32.2%), sepsis (23%), abscess formation (19.5%), and ulcer development (19.5%). Medical management was with antibiotic therapy, including mostly penicillin (26.5%), aminoglycoside (22.1%), nitroimidazole (20.2%) and cephalosporin (19.6%). Debridement (46.7%), and incision and drainage (44.4%) were the most implemented surgical interventions. Nursing care, as found in patients’ hospital records were predominantly on medication administration (98.0%), vital signs assessment (90.5%) and patient assessment (53%). Cellulitis therefore was found among a substantial number of patients and management was predominantly with combination antibiotics therapy and inadequate nursing care.

Methods Six hundred twenty consecutive HCV-related cirrhotic patients were evaluated for cellulitis. Demographic and clinical data were evaluated, along with blood and skin cultures. Severity of cirrhosis was assessed using Child-Pugh score. In-hospital mortality was assessed. Results Seventy-seven (12.4%) cirrhotic patients had cellulitis (25 with compensated and 52 with decompensated disease). Smoking and venous insufficiency were risk factors of cellulitis in compensated cirrhosis. Leg edema, ascites, hyperbilrubinemia and hypoalbuminemia were risk factors in decompensated cirrhosis. Gram-positive bacteria (Staphylococcus spp. and Streptococcus pyogenes) were the infective organisms in compensated patients, while gram negative bacteria (Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa) were the predominant organisms in decompensated cirrhosis. Fungi (Candida albicans and Aspergillus niger) were detected in 3 decompensated cases. In-hospital mortality in patients with cellulitis was 27.3%, approaching 100% in decompensated patients with gram-negative cellulitis. Prolonged hospitalization, higher model for end-stage liver disease (MELD)-Na score, septic shock, local complication, and recurrent cellulitis were predictors of mortality. Conclusions Cellulitis in compensated cirrhosis is different from that of decompensated patients regarding microorganisms, pathogenesis, and prognosis. Cellulitis has a poor prognosis, with mortality rates approaching 100% in decompensated patients with gram-negative cellulitis. Stratifying patients according to severity of cirrhosis is important to identify the proper empirical antibiotic and to decide the proper means of care.

Abstract
Background: Erysipelas and cellulitis are usually caused by betahaemolytic streptococci but the aetiology is often difficult to verify in clinical practice. Methods: Patients with erysipelas or cellulitis were analysed for betahaemolytic streptococci in samples from multiple body sites, including the perineum and the anal canal, during the acute episode and at follow up. Healthy control persons were sampled from the same sites. Results: Betahaemolytic streptococci group A, C or G were identified in 23/28 (82%) patients, most commonly group G. A wound or ulcer, present in 16/28 (57%), was colonized in 8/16 (50%). The perineum and anal canal were colonized in 11/28 (39%) and 10/28 (36%), respectively. At follow-up after about 4 weeks, only 4/28 (14%) were colonized (p<.001). In 39 healthy control persons, no betahaemolytic streptococci group A were found, groups C or G were found in 4/39 (10%). Group B streptococci were more often identified in controls, than in patients,12/39 (31%). Conclusions: Acute episodes of erysipelas or cellulitis are associated with colonization of betahaemolytic streptococci at multiple sites including the perineum and anal canal, in particular serogroup G. This may be important for choice of primary antibiotic therapy and possibilities for prevention of relapses.

Abstract
BACKGROUND Cellulitis is a common painful infection of the skin and underlying tissues that recurs in approximately one-third of cases. The only proven strategy to reduce the risk of recurrence is long-term, low-dose antibiotics. Given current concerns about antibiotic resistance and the pressure to reduce antibiotic prescribing, other prevention strategies are needed. OBJECTIVES To explore patients' views about cellulitis and different ways of preventing recurrent episodes. METHODS Adults aged ≥ 18 years with a history of first-episode or recurrent cellulitis were invited through primary care, hospitals and advertising to complete a survey, take part in an interview or both. RESULTS Thirty interviews were conducted between August 2016 and July 2017. Two hundred and forty surveys were completed (response rate 17%). Triangulation of quantitative and qualitative data showed that people who have had cellulitis have wide-ranging beliefs about what can cause cellulitis and are often unaware of risk of recurrence or potential strategies to prevent recurrence. Enhanced foot hygiene, applying emollients daily, exercise and losing weight were more popular potential strategies than the use of compression stockings or long-term antibiotics. Participants expressed caution about long-term oral antibiotics, particularly those who had experienced only one episode of cellulitis. CONCLUSIONS People who have had cellulitis are keen to know about possible ways to prevent further episodes. Enhanced foot hygiene, applying emollients daily, exercise and losing weight were generally viewed to be more acceptable, feasible strategies than compression or antibiotics, but further research is needed to explore uptake and effectiveness in practice.

Abstract
Erysipelas is a severe streptococcal infection of the skin primarily spreading through the lymphatic vessels. Penicillin is the treatment of choice. The most common complication consists in relapses which occur in up to 40% or more of patients despite appropriate antibiotic treatment. They cause lymphatic damage resulting in irreversible lymphedema and ultimately elephantiasis nostras and lead to major health restrictions and high socio-medical costs. Prevention of relapses is an unmet need, because even long-term prophylactic penicillin application does eventually not reduce the risk of recurrence. In this article we assess risk factors and causes of erysipelas recurrence. A systematic literature search for clinical studies addressing potential causes and measures for prevention of erysipelas recurrence was combined with a review of experimental and clinical data assessing the ability and clinical relevance of streptococci for intracellular uptake and persistence. The literature review found that venous insufficiency, lymphedema, and intertrigo from fungal infections are considered to be major risk factors for recurrence of erysipelas but cannot adequately explain the high recurrence rate. As hitherto unrecognized likely cause of erysipelas relapses we identify the ability of streptococci for intracellular uptake into and persistence within epithelial and endothelial cells and macrophages. This creates intracellular streptococcal reservoirs out of reach of penicillins which do not reach sufficient bactericidal intracellular concentrations. Incomplete streptococcal elimination due to intracellular streptococcal persistence has been observed in various deep tissue infections and is considered as cause of relapsing streptococcal pharyngitis despite proper antibiotic treatment. It may also serves as endogenous infectious source of erysipelas relapses. We conclude that the current antibiotic treatment strategies and elimination of conventional risk factors employed in erysipelas management are insufficient to prevent erysipelas recurrence. The reactivation of streptococcal infection from intracellular reservoirs represents a plausible explanation for the frequent occurrence erysipelas relapses. Prevention of erysipelas relapses therefore demands for novel antibiotic strategies capable of eradicating intracellular streptococcal persistence.

Abstract
Background It is a challenge to treat onychomycosis due to frequent treatment failures and relapses. Systemic and topical therapies need to be combined to improve cure rates. Antifungal susceptibility might play a role in the treatment resistance of onychomycosis. Aims To compare the safety and effectiveness of amorolfine 5% nail lacquer + oral fluconazole versus only oral fluconazole in the treatment of fingernail onychomycosis. Methodology In this double-blind trial (CTRI/2015/02/005369), patients were randomized (1:1) into amorolfine 5% nail lacquer + fluconazole and dummy lacquer + fluconazole. Treatment was given for 3 months with monthly follow-ups. Antifungal sensitivity was carried out for Candida. Effectiveness was assessed by reduction in the number and percentage area of nails involved and mycological cure. At the end of 3-month treatment period, the association between drug sensitivity and treatment response was explored for the Candida infections. Results Among 30 study participants, the combination group showed significantly lower number of nail involvement (P = 0.004) and percentage nail involvement (P = 0.005) than only fluconazole group. Pretreatment fungal culture showed a comparable number of dermatophytes, Candida, Aspergillus in both the groups. Sensitivity testing was done for the isolated Candida species. Antifungal sensitivity for Candida (n = 11) was tested, and 8 (72.7%) of the organisms were sensitive to fluconazole (minimum inhibitory concentration [MIC] 1.25 ± 1.19 μg/ml), 100% were sensitive to itraconazole (MIC 0.0726 ± 0.021 μg/ml), and 3 (27.3%) were susceptible-dose dependent (S-DD) to fluconazole (MIC 16 μg/ml). Fluconazole only group patients with Candida who showed resistance to fluconazole did not respond to therapy; however, patients in the combination group showed moderate improvement (reduction in area involvement = 55.56 ± 35.36%). Conclusion The combination of amorolfine/fluconazole achieved a higher cure rate not only for sensitive fungus but also for those which were S-DD to fluconazole.

Abstract
Cellulitis and erysipelas are local soft tissue infections that occur following the entry of bacteria through a disrupted skin barrier. These infections are relatively common and early diagnosis is essential to treatment success. As dermatologists, we need to be familiar with the clinical presentation, diagnosis, and treatment of these infections. In this article, we provide a review of the literature and update on clinical manifestations, predisposing factors, microbiology, diagnosis, treatment, and complications. We also review the current situation in Chile.

Abstract
The existing approaches to onychomycosis demonstrate limited success since the commonly used oral administration and topical cream only achieve temporary effective drug concentration at the fungal infection sites. An ideal therapeutic approach for onychomycosis should have (i) the ability to introduce antifungal drugs directly to the infected sites; (ii) finite intradermal sustainable release to maintain effective drug levels over prolonged time; (iii) a reporter system for monitoring maintenance of drug level; and (iv) minimum level of inflammatory responses at or around the fungal infection sites. To meet these expectations, we introduced ketoconazole-encapsulated cross-linked fluorescent supramolecular nanoparticles (KTZ⊂c-FSMNPs) as an intradermal controlled release solution for treating onychomycosis. A two-step synthetic approach was adopted to prepare a variety of KTZ⊂c-FSMNPs. Initial characterization revealed that 4800 nm KTZ⊂c-FSMNPs exhibited high KTZ encapsulation efficiency/capacity, optimal fluorescent property, and sustained KTZ release profile. Subsequently, 4800 nm KTZ⊂c-FSMNPs were chosen for in vivo studies using a mouse model, wherein the KTZ⊂c-FSMNPs were deposited intradermally via tattoo. The results obtained from (i) in vivo fluorescence imaging, (ii) high-performance liquid chromatography quantification of residual KTZ, (iii) matrix-assisted laser desorption/ionization mass spectrometry imaging mapping of KTZ distribution in intradermal regions around the tattoo site, and (iv) histology for assessment of local inflammatory responses and biocompatibility, suggest that 4800 nm KTZ⊂c-FSMNPs can serve as an effective treatment for onychomycosis.

Abstract
OBJECTIVE To summarise available data on the risk factors, complications and the factors associated with complications of lower limb cellulitis in Africa. METHODS We did electronic searches on PubMed, EMBASE, Scopus and African Journals Online from 1 January 1986 to 30 October 2017, extracted and summarised data on the risk factors, complications and the factors associated with the complications of lower limb cellulitis from eligible literature. RESULTS A total of seven studies were retained for final review after the search and screening processes. Local risk factors of cellulitis reported were: disruption of the skin barrier, neglected wounds, toe-web intertrigo, leg ulcers, use of depigmentation drugs and leg oedema. Obesity was the only reported general risk factor of cellulitis. Five studies reported on the complications of cellulitis which included: abscess formation, necrotising fasciitis, bullae, haemorrhagic lesions, necrosis, phlebitis and amputations. Nicotine addiction, chronic use of non-steroidal anti-inflammatory drugs, delay in the initiation of antibiotic treatment and elevated erythrocyte sedimentation rate were risk factors of complications of lower limb cellulitis identified from three studies. CONCLUSION This review highlights the important role of local risk factors in the pathogenesis of lower limb cellulitis in Africa. The association between voluntary skin depigmentation and lower limb cellulitis should alert public health authorities and the general population to the health risks associated with this practice. The identification and improved management of the risk factors of lower limb cellulitis and its complications could go a long way in decreasing the morbidity and health costs incurred by lower limb cellulitis in Africa.

Abstract
Wound healing is a highly coordinated and complex process, and there can be devastating consequences if it is interrupted. It is believed that, in combination with host factors, microorganisms in a wound bed can not only impair wound healing but can lead to stalled, chronic wounds. It is hypothesized that the wound microbiota persists in chronic wounds as a biofilm, recalcitrant to antibiotic and mechanical intervention. Cultivation-based methods are the gold standard for identification of pathogens residing in wounds. However, these methods are biased against fastidious organisms, and do not capture the full extent of microbial diversity in chronic wounds. Thus, the link between specific microbes and impaired healing remains tenuous. This is partially because local infection and, more specifically, the formation of a biofilm, is difficult to diagnose. This has led to research efforts aimed at understanding if biofilm formation delays healing and leads to persistent and chronic infection. Circumventing challenges associated with culture-based estimations, advances in high-throughput sequencing analysis has revealed that chronic wounds are host to complex, diverse microbiomes comprising multiple species of bacteria and fungi. Here, we discuss how the use of genomic methodologies to study wound microbiomes has advanced the current understanding of infection and biofilm formation in chronic wounds.

Abstract
Introduction Dermatophytosis is a superficial fungal infection limited to the stratum corneum of the epidermis, or to the hair and nails, and constitutes an important public health problem because of its high prevalence and associated morbidity. Dermatophyte fungi, especially 2 species, Trichophyton rubrum and Trichophyton mentagrophytes, are the predominant pathogens. Topical antifungal drugs, mainly azoles or allyamines, are currently used for the treatment of dermatophytoses, although in some cases, such as in nail and hair involvement, systemic treatment is required. However, therapeutic efficacy of current antifungal agents can be limited by their side effects, costs, and the emergence of drug resistance among fungi. Plant extracts represent a potential source of active antimicrobial agents, due to the presence of a variety of chemical bioactive compounds. In the present work, we evaluated in silico and in vitro the antifungal activity of an extract of the medicinal plant Cardiospermum halicacabum against T. rubrum suggesting a potential interaction with Hsp90 as playing an important role in both pathogenicity and drug susceptibility of T. rubrum. Methods We investigated in vitro the effect of different concentrations of C. halicacabum (from 500 to 31.25 µg) against a clinical isolate of T. rubrum. Furthermore, using a computational assessment, the interaction between different C. halicacabum active compounds and the fungal Hsp90 was also investigated. Results Our results indicate a clear-cut antifungal activity of the total plant extract at the highest concentrations (500 and 250 µg). Among all tested C. halicacabum compounds, the luteolin and rutin molecules have been identified in silico as the most important potential inhibitors of Hsp90. Based on these data, luteolin and rutin were also individually assessed for their antifungal activity. Results demonstrate that both substances display an antifungal effect, even if lower than that of the total plant extract. Conclusion Our data indicate a strong fungistatic effect of C. halicacabum against T. rubrum, suggesting its potential therapeutic efficacy in the treatment of dermatophytoses. Additionally, C. halicacabum compounds, and particularly luteolin and rutin, are all possible Hsp90 interactors, explaining their fungistatic activity.

Abstract
OBJECTIVES The aim of our study was to determine the effectiveness of using ultrasound (US) to increase the permeability of the nail, with the goal of improving outcomes in the treatment of onychomycosis. METHODS Porcine nails were used because of their similarity to human nails. A hydrophilic blue dye was used as a drug-mimicking compound. Two sets of experiments were performed: luminosity experiments to assess the dye levels inside the nail after US and sham treatments and diffusion cell experiments for determination of changes in nail permeability due to US application. In both sets of experiments, planar US transducers were used to sonicate the nails at frequencies of 400, 600, and 800 kHz and 1 MHz, an intensity of 1 W/cm2 , and a duration of 5 min in a continuous mode. Modeling studies were also performed to assess the safety of US application to the human toe for later clinical studies. RESULTS In the luminosity experiments, application of US at frequencies of 600 and 800 kHz led to statistically significant results (P < .05), with an increase in dye delivery into the nail of up to 95% compared to control values. The diffusion cell results found statistical significance (P < .05) at all applied frequencies, with up to a 70% increase in the nail permeability compared to the control. Safety modeling studies found a maximal temperature increase of 4.4 °C in the bone. CONCLUSIONS Our proposed US method may offer an alternative for improved treatment of onychomycosis. The current maximal temperature increase was found to be at the safety limit, and so pulsing and other alternatives will be investigated to minimize this temperature increase.

Abstract
Significance: Culture-independent methods have revealed the diverse and dynamic bacterial communities that colonize chronic wounds. Only recently have studies begun to examine fungal colonization and interactions with the bacterial component of the microbiome, their relationship with the host, and influence on wound outcomes. Recent Advances: Studies using culture-independent sequencing methods reveal that fungi often go undetected in wounds. Candida spp. and Cladosporidium spp. are the most commonly identified fungi in wounds. The wound environment may promote multispecies biofilm formation between bacteria and fungi in wounds, with implications for pathogenicity, treatment, and outcomes. Critical Issues: Identifying microorganisms that are problematic for healing will require a comprehensive understanding of all members of the polymicrobial wound community, including fungi and bacteria. Improved reference databases and bioinformatics tools for studying fungal communities will stimulate further research into the fungal microbiome. Future Directions: Continued study of polymicrobial wound communities using culture-independent methods will further our understanding of the relationships between microbial bioburden, the host response, and impact on healing, complications, and patient outcomes. Future studies should encompass all types of microbiota, including fungi, and focus on potential multi-kingdom interactions that contribute to pathogenicity, biofilm formation, and poor outcomes.

Abstract
Introduction According to our clinical experience, cellulitis is common in summer; however, very few studies have mentioned this trend. Methods Using Google Trends, we analyzed the monthly data of Google searches for "cellulitis" from 31 countries on 6 continents. Results Seasonality explained 34%-92% of the variability in search volume, with peaks occurring in summer months. Conclusion The analyses offered new insights into the epidemiology of cellulitis on national and international scales. Clinical data are needed to validate the Internet search data.

Abstract
BACKGROUND The prevention, early diagnosis and treatment of onychomycosis is of great importance for professional athletes to avoid physical limitations by complications. So far, there is only little data on the prevalence of dermatomycosis in professional athletes. OBJECTIVES The aim of the study was to detect the prevalence of dermatomycosis in professional football players compared to the general population. MATERIALS AND METHODS The prospective, non-interventional, controlled study on the prevalence of dermatomycosis in professional football players was carried out on football players of a German Bundesliga team compared with a previously studied, equivalently aged German working population. A questionnaire survey, a dermatological check-up and a microbiological detection of pathogens in cases of suspicion were performed. RESULTS Data of 84 football players (n = 45 in 2013; n = 39 in 2015) were compared to data of n = 8186 male employees between 17 and 35 years of age. In the group of athletes, there were findings of 60.7% onychomycosis, 36.9% of tinea pedis and 17.8% of pityriasis versicolor. In the group of the age-equivalent general German working population the findings were: onychomycosis 3.3%, tinea pedis 3.2%, pityriasis versicolor 1.4%. CONCLUSION Our study shows a clearly higher risk for fungal diseases of the skin especially on the feet of professional football players. The results show a necessity for elucidation within prevention and the establishment of an appropriate therapy of dermatomycosis for professional football players.

Abstract
Hospital-acquired infections have been recognized as a significant factor in increased morbidity and mortality across our health system. Unique to infections associated with inpatient psychiatric hospitalization is the additional hypothesized association of the role that antipsychotic agents and/or underlying disease may play in an increased risk for infection. In this paper, we explore the types of infections diagnosed in an inpatient psychiatric hospital, the demographics of the patients infected, and whether or not the patient was on antipsychotic agents at the time of infection.

Abstract
OBJECTIVES To examine the correlations between elements of feet-washing behavior, presence of tinea pedis (TP), and patients' background characteristics in order to identify a concrete intervention method to prevent TP. DESIGN AND PARTICIPANTS A cross-sectional study of 30 patients with diabetes (16 with TP) who were admitted to or visited the university hospital. MAIN OUTCOME MEASURES The presence of TP was confirmed by the detection of dermatophytes by direct microscopy. Data on elements of feet-washing behavior, such as scrubbing between the toes, were collected by observing recorded videos of participants normally washing their feet as they do at home. The patients' background characteristics included demographic data; diabetes-related factors; patient knowledge regarding diabetes, foot problems, and TP prevention; purpose for feet washing; and any difficulties in feet washing. MAIN RESULTS The number of times patients scrubbed between their toes while washing with soap was significantly lower in patients with TP (odds ratio, 0.95; P = .036; with a cutoff value of 35 times) and those who had difficulty in reaching their feet with their hands (B = -14.42, P = .041). CONCLUSIONS An effective foot-washing protocol should include specific instructions for patients to scrub between their toes at least 35 times in all 8 spaces while washing with soap. Appropriate advice is also needed for individuals who have difficulty reaching their feet with their hands. Education about appropriate foot-washing behavior may potentially prevent TP.

Abstract
BACKGROUND Erysipelas and cellulitis (hereafter referred to as 'cellulitis') are common bacterial skin infections usually affecting the lower extremities. Despite their burden of morbidity, the evidence for different prevention strategies is unclear. OBJECTIVES To assess the beneficial and adverse effects of antibiotic prophylaxis or other prophylactic interventions for the prevention of recurrent episodes of cellulitis in adults aged over 16. SEARCH METHODS We searched the following databases up to June 2016: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and LILACS. We also searched five trials registry databases, and checked reference lists of included studies and reviews for further references to relevant randomised controlled trials (RCTs). We searched two sets of dermatology conference proceedings, and BIOSIS Previews. SELECTION CRITERIA Randomised controlled trials evaluating any therapy for the prevention of recurrent cellulitis. DATA COLLECTION AND ANALYSIS Two authors independently carried out study selection, data extraction, assessment of risks of bias, and analyses. Our primary prespecified outcome was recurrence of cellulitis when on treatment and after treatment. Our secondary outcomes included incidence rate, time to next episode, hospitalisation, quality of life, development of resistance to antibiotics, adverse reactions and mortality. MAIN RESULTS We included six trials, with a total of 573 evaluable participants, who were aged on average between 50 and 70. There were few previous episodes of cellulitis in those recruited to the trials, ranging between one and four episodes per study.Five of the six included trials assessed prevention with antibiotics in participants with cellulitis of the legs, and one assessed selenium in participants with cellulitis of the arms. Among the studies assessing antibiotics, one study evaluated oral erythromycin (n = 32) and four studies assessed penicillin (n = 481). Treatment duration varied from six to 18 months, and two studies continued to follow up participants after discontinuation of prophylaxis, with a follow-up period of up to one and a half to two years. Four studies were single-centre, and two were multicentre; they were conducted in five countries: the UK, Sweden, Tunisia, Israel, and Austria.Based on five trials, antibiotic prophylaxis (at the end of the treatment phase ('on prophylaxis')) decreased the risk of cellulitis recurrence by 69%, compared to no treatment or placebo (risk ratio (RR) 0.31, 95% confidence interval (CI) 0.13 to 0.72; n = 513; P = 0.007), number needed to treat for an additional beneficial outcome (NNTB) six, (95% CI 5 to 15), and we rated the certainty of evidence for this outcome as moderate.Under prophylactic treatment and compared to no treatment or placebo, antibiotic prophylaxis reduced the incidence rate of cellulitis by 56% (RR 0.44, 95% CI 0.22 to 0.89; four studies; n = 473; P value = 0.02; moderate-certainty evidence) and significantly decreased the rate until the next episode of cellulitis (hazard ratio (HR) 0.51, 95% CI 0.34 to 0.78; three studies; n = 437; P = 0.002; moderate-certainty evidence).The protective effects of antibiotic did not last after prophylaxis had been stopped ('post-prophylaxis') for risk of cellulitis recurrence (RR 0.88, 95% CI 0.59 to 1.31; two studies; n = 287; P = 0.52), incidence rate of cellulitis (RR 0.94, 95% CI 0.65 to 1.36; two studies; n = 287; P = 0.74), and rate until next episode of cellulitis (HR 0.78, 95% CI 0.39 to 1.56; two studies; n = 287). Evidence was of low certainty.Effects are relevant mainly for people after at least two episodes of leg cellulitis occurring within a period up to three years.We found no significant differences in adverse effects or hospitalisation between antibiotic and no treatment or placebo; for adverse effects: RR 0.87, 95% CI 0.58 to 1.30; four studies; n = 469; P = 0.48; for hospitalisation: RR 0.77, 95% CI 0.37 to 1.57; three studies; n = 429; P = 0.47, with certainty of evidence rated low for these outcomes. The existing data did not allow us to fully explore its impact on length of hospital stay.The common adverse reactions were gastrointestinal symptoms, mainly nausea and diarrhoea; rash (severe cutaneous adverse reactions were not reported); and thrush. Three studies reported adverse effects that led to discontinuation of the assigned therapy. In one study (erythromycin), three participants reported abdominal pain and nausea, so their treatment was changed to penicillin. In another study, two participants treated with penicillin withdrew from treatment due to diarrhoea or nausea. In one study, around 10% of participants stopped treatment due to pain at the injection site (the active treatment group was given intramuscular injections of benzathine penicillin).None of the included studies assessed the development of antimicrobial resistance or quality-of-life measures.With regard to the risks of bias, two included studies were at low risk of bias and we judged three others as being at high risk of bias, mainly due to lack of blinding. AUTHORS' CONCLUSIONS In terms of recurrence, incidence, and time to next episode, antibiotic is probably an effective preventive treatment for recurrent cellulitis of the lower limbs in those under prophylactic treatment, compared with placebo or no treatment (moderate-certainty evidence). However, these preventive effects of antibiotics appear to diminish after they are discontinued (low-certainty evidence). Treatment with antibiotic does not trigger any serious adverse events, and those associated are minor, such as nausea and rash (low-certainty evidence). The evidence is limited to people with at least two past episodes of leg cellulitis within a time frame of up to three years, and none of the studies investigated other common interventions such as lymphoedema reduction methods or proper skin care. Larger, high-quality studies are warranted, including long-term follow-up and other prophylactic measures.

Abstract
Background Cellulitis is a common infection of the skin and subcutaneous tissues. It is associated with significant morbidity from necrosectomies and amputations especially in sub-Saharan Africa. We aimed at identifying the risk factors and burden of lower limb cellulitis to inform preventive strategies in Cameroon. Methods This was a hospital–based case-control study carried out in the Bamenda Regional Hospital (BRH) between September 2015 and August 2016. Cases were defined as consenting adults admitted to the surgical unit who presented with a localised area of lower limb erythema, warmth, oedema and pain, associated with fever (temperature ≥ 38 °C) and/or chills of sudden onset. Controls were adults hospitalised for diseases other than cellulitis, necrotising fasciitis, myositis, abscess or other variants of dermo-hypodermitis. Cases and controls were matched (1:2) for age and sex. Results Of the 183 participants (61 cases of cellulitis and 122 controls) included in the study, the median age was 52 years [Interquartile range (IQR): 32.5–74.5]. After controlling for potential confounders, obesity [adjusted odds ratio (AOR) = 4.7, 95% CI (1.5–14.7); p = 0.009], history of skin disruption [AOR = 12.4 (3.9–39.1); p < 0.001], and presence of toe-web intertrigo [AOR = 51.4 (11.7–225.6); p < 0.001] were significantly associated with cellulitis. Median hospital stay was longer (14 days [IQR: 6–28]) in cases compared to the controls (3 days [IQR: 2–7]). Among the cases, Streptococci species were the most frequent (n = 50, 82%) isolated germ followed by staphylococci species (n = 9, 15%). Patients with cellulitis were more likely to undergo necrosectomy (OR: 21.2; 95% CI: 7.6–59.2). Toe-web intertrigo had the highest (48.9%) population attributable risk for cellulitis, followed by history of disruption of skin barrier (37.8%) and obesity (20.6%). Conclusion This study showed a high disease burden among patients with cellulitis. While risk factors identified are similar to prior literature, this study provides a contextual evidence-base for clinicians in this region to be more aggressive in management of these risk factors to prevent disease progression and development of cellulitis.

Abstract
BACKGROUND Nutritional status is a well-known risk factor for metabolic and endocrine disorders. Recent studies suggest that dietary intake also affects immune function and as a consequence infection risk. AIMS This reviews aims to give an overview on the effect of body weight on infection rate at different periods of life. SOURCES Clinically relevant prospective, cross-sectional and case-control community-based studies are summarized. CONTENT In children and adolescents underweight is a significant risk factor for infection especially in developing countries, probably reflecting malnutrition and poor hygienic standards. Data from industrialized countries suggest that infection rate is also increased in obese children and adolescents. Similarly, several studies suggest a U-shaped increased infection rate in both underweight and obese adults. In the latter, infections of the skin and respiratory tract as well as surgical-site infections have consistently been reported to be more common than in normal-weight participants. Paradoxically, mortality of critically ill patients was reduced in obesity in some studies. IMPLICATIONS Several studies in children or adults suggest that both underweight and obesity are associated with increased infection risk. However, confounding factors such as malnutrition, hygienic status and underlying disease or co-morbidities might aggravate accurate assessment of the impact of body weight on infection risk.

Infectious diseases specialist management improves outcomes for outpatients diagnosed with cellulitis in the emergency department: a double cohort study. Diagn Microbiol Infect Dis 2017; 87:371-375.

Abstract
Three hospital emergency rooms (ERs) routinely referred all cases of cellulitis requiring outpatient intravenous antibiotics, to a central ER-staffed cellulitis clinic. We performed a retrospective cohort study of all patients seen by the ER clinic in the last 4months preceding a policy change (ER management cohort [ERMC]) (n=149) and all those seen in the first 3months of a new policy of automatic referral to an infectious disease (ID) specialist-supervised cellulitis clinic (ID management cohort [IDMC]) (n=136). Fifty-four (40%) of 136 patients in the IDMC were given an alternative diagnosis (noncellulitis), compared to 16 (11%) of 149 in the ERMC (P<0.0001). Logistic regression-demonstrated rates of disease recurrence were lower in the IDMC than the ERMC (hazard ratio [HR], 0.06; P=0.003), as were rates of hospitalization (HR, 0.11; P=0.01). There was no significant difference in mortality. Automatic ID consultation for cellulitis was beneficial in differentiating mimickers from true cellulitis, reducing recurrence, and preventing hospital admissions.

Abstract
Onychomycosis is a fungal infection, and, as such, one of the goals of treatment should be eradication of the infective agent. Despite this, in contrast to dermatologists, many podiatric physicians do not include antifungals in their onychomycosis treatment plans. Before initiating treatment, confirmation of mycologic status via laboratory testing (eg, microscopy with potassium hydroxide preparation, histopathology with periodic acid-Schiff staining, fungal culture, and polymerase chain reaction) is important; however, more podiatric physicians rely solely on clinical signs than do dermatologists. These dissimilarities may be due, in part, to differences between specialties in training, reimbursement patterns, or practice orientation, and to explore these differences further, a joint podiatric medicine-dermatology roundtable was convened. In addition, treatment options have been limited owing to safety concerns with available oral antifungals and relatively low efficacy with previously available topical treatments. Recently approved topical treatments-efinaconzole and tavaborole-offer additional options for patients with mild-to-moderate disease. Debridement alone has no effect on mycologic status, and it is recommended that it be used in combination with an oral or topical antifungal. There is little to no clinical evidence to support the use of lasers or over-the-counter treatments for onychomycosis. After a patient has achieved cure (absence of clinical signs or absence of fungus with minimal clinical signs), lifestyle and hygiene measures, prophylactic/maintenance treatment, and proactive treatment for tinea pedis, including in family members, may help maintain this status.

Abstract
Nail disorders are a common presenting complaint for both the primary care physician and the dermatologist. Nail diagnoses are broad in scope and include infectious, inflammatory, and neoplastic conditions. Onychomycosis is an especially common nail condition, and treatment should always be preceded by appropriate fungal studies for confirmation of diagnosis. Inflammatory conditions of the nail unit can mimic onychomycosis, and a dermatologist can assist with diagnosis and treatment recommendations. Likewise, subungual tumors often require biopsy, and should be evaluated by a dermatologist who is experienced in nail evaluation and treatment.

Abstract
Rich clinical experiences indicate that toe web intertrigo is a major predisposing condition for cellulitis/acute dermatolymphango adenitis (ADLA) and the number of lesions is the strongest predictor of frequency of ADLA in lymphedema (LE) patients. However, there is scanty information on the risk factors for the establishment of chronic toe web intertrigo in LE patients. We performed a case-control study recruiting 52 lower limb LE with intertrigo and 52 lower limb LE without intertrigo in community settings and assessed general and local potential risk factors for chronic intertrigo. Analysis of local risk factors revealed that topical application of oil, tingling and numbness of the extremities were associated independently with chronic intertrigo. In multivariate analysis, LE grades III and IV were associated with chronic intertrigo, after adjusting for tingling and numbness, prophylactic antibiotic, age group, and gender. From a public health perspective, LE patients of grades III and IV and patients under antibiotic prophylaxis should be self-motivated to look for the early symptoms of toe web intertrigo to prevent chronic stage and recurrent episodes of cellulitis. Patients with history of tingling and numbness of the periphery need to be monitored for pressure effects leading to poor vascularization and delayed healing of intertrigo.
