Complication of Soft Tissue Fillers: Prevention and Management Review

The use of dermal fillers has increased manifold over the past decade, which has been attributed to the ever-increasing need of the population for being young. Fillers have become quite popular both among patients and treating physicians due to their quick and quite predictable results. Filler injection is a safe procedure in the hands of an experienced provider using appropriate technique. Nevertheless, various adverse effects to fillers have been reported that range from mild injection site complications, such as pain and bruising, to severe complications, like tissue necrosis, retinal artery occlusion, and infections. The esthetic provider should be aware of and be able to quickly recognize such complications, and be confident in managing them. In this article we highlight the various adverse effects noted with the use of fillers and discuss prevention and management. J Drugs Dermatol. 2020;19(9):829-832. doi:10.36849/JDD.2020.5084.

The Role of Porphyrinoid Photosensitizers for Skin Wound Healing

Microorganisms, usually bacteria and fungi, grow and spread in skin wounds, causing infections. These infections trigger the immune system and cause inflammation and tissue damage within the skin or wound, slowing down the healing process. The use of photodynamic therapy (PDT) to eradicate microorganisms has been regarded as a promising alternative to anti-infective therapies, such as those based on antibiotics, and more recently, is being considered for skin wound-healing, namely for infected wounds. Among the several molecules exploited as photosensitizers (PS), porphyrinoids exhibit suitable features for achieving those goals efficiently. The capability that these macrocycles display to generate reactive oxygen species (ROS) gives a significant contribution to the regenerative process. ROS are responsible for avoiding the development of infections by inactivating microorganisms such as bacteria but also by promoting cell proliferation through the activation of stem cells which regulates inflammatory factors and collagen remodeling. The PS can act solo or combined with several materials, such as polymers, hydrogels, nanotubes, or metal-organic frameworks (MOF), keeping both the microbial photoinactivation and healing/regenerative processes' effectiveness. This review highlights the developments on the combination of PDT approach and skin wound healing using natural and synthetic porphyrinoids, such as porphyrins, chlorins and phthalocyanines, as PS, as well as the prodrug 5-aminolevulinic acid (5-ALA), the natural precursor of protoporphyrin-IX (PP-IX).

Hospital-acquired Skin and Skin-structure Infection in COVID-19 Infected Patient with Prolonged Hospitalization

Acute bacterial skin and skin-structure infections (ABSSSI) is defined in 2013 by the US Food and Drug Administration as a bacterial cellulitis/erysipelas, major skin abscesses, and wound infections. The Infectious Diseases Society of America (IDSA) in 2014 classifies skin and soft-tissue infection (SSTI) as either non-purulent (which includes cellulitis, erysipelas, and necrotizing infection) or purulent (including furuncle, carbuncle, and abscess). Among hospitalized patients with SSTI, healthcare-associated infections account for 73.5% of all cases. Notably, skin and skin-structure infections caused by Pseudomonas aeruginosa, a common hospital pathogen, was reported to cause higher total cost and longer hospital length of stay compared to non-P. aeruginosa cases, despite causing only approximately 5.7% of all healthcare-associated SSTIs. Infection with P. aeruginosa should always be considered in non-healing skin infections in patients with prolonged hospitalization and antibiotic exposure. Tissue culture, preferably taken by surgical debridement, should be promptly performed; and when hospital-infection is suspected, appropriate antibiotics should be started along with removal of all devitalized tissue and to promote skin and soft tissue healing. Expedited discharge should be considered when possible, with adequate antibiotic treatment and follow up for definitive wound treatment.

[Rubor, calor, dolor, tumor : skin and soft tissue infections]

Skin infections are a frequent cause of consultation, yet the diagnosis can be challenging for physicians. Microbiological documentation is rare, and empiric antibiotic regimens should cover the most commonly identified bacteria, i.e. streptococci Staphylococcus aureus. Other pathogens should be considered in case of immunosuppression or certain exposures. Necrotizing fasciitis (NF) is a severe but rare infection. Early surgical management in parallel with antibiotics is the cornerstone of treatment. Despite the high incidence of these infections, little progress has been made in their management and some areas of uncertainty exist, especially regarding the optimal duration of treatment, the prevention of recurrences and the use of polyclonal immunoglobulins for NF. This article reviews the main aspects of diagnosis and treatment of these infections.

Efficacy of extracorporeal shockwave therapy in the treatment of postherpetic neuralgia: A pilot study

Established conventional treatments for postherpetic neuralgia (PHN) and postherpetic itch (PHI) are difficult and often disappointing. In this study, the authors investigated the effect and mechanisms of extracorporeal shockwave therapy (ESWT) on pain and itch associated with PHN and PHI.Thirteen patients, 50 to 80 years of age, with symptoms associated with PHN or PHI (duration of persistent pain >3 months) and complaints of pain or itch rated >4 on a numerical rating scale (NRS), were included. ESWT was administered using a shockwave device (Piezo Shockwave, Richard Wolf GmbH, Knittlingen, Germany) to skin areas affected by pain or itch. An energy flux density of 0.09 to 0.16 mJ/mm at a frequency of 5 Hz and 2000 impulses was administered at 3-day intervals for 6 sessions. The NRS, 5D-Itch Scale, and Patients Global Impression of Change (PGIC) scale were used to evaluate the efficacy of ESWT.NRS scores of pain and itch and 5D-Itch Scale scores decreased significantly compared with before treatment and at the end of the treatment sessions (P < .0001, P = .001, P = .0002, respectively). There was a statistically significant difference between PGIC scores, which were checked every 2 sessions (P < .0001).ESWT is a noninvasive modality that significantly reduced PHN-associated pain and itch.

Barriers and Enablers of Health Service Utilisation for Childhood Skin Infections in Remote Aboriginal Communities of Western Australia

In Australia, children living in remote Aboriginal communities experience high rates of skin infections and associated complications. Prompt presentation to primary care health services is crucial for early diagnosis and treatment. We performed a qualitative study in four remote Aboriginal communities in the Pilbara region of Western Australia to explore factors that affected health service utilisation for childhood skin infections in this setting. The study consisted of semistructured interviews and focus group discussions with parents and carers (n = 16), healthcare practitioners (n = 15) and other community service providers (n = 25). We used Andersen's health service utilisation model as an analytical framework. Our analysis captured a wide range of barriers that may undermine timely use of health services for childhood skin infections. These included general factors that illustrate the importance of cultural competency amongst healthcare providers, patient-centred care and community engagement. Relating specifically to health service utilisation for childhood skin infections, we identified their apparent normalisation and the common use of painful benzathine penicillin G injections for their treatment as important barriers. Health service utilisation in this setting may be enhanced by improving general awareness of the significance of childhood skin infections, actively engaging parents and carers in consultation and treatment processes and strengthening community involvement in health service activities.

Self-care habits among people who inject drugs with skin and soft tissue infections: a qualitative analysis

BACKGROUND

Injection drug use is on the rise in the USA, and skin and soft tissue infections (SSTI) are a common complication, resulting in significant morbidity and mortality. Due to structural barriers to care-seeking, many people who inject drugs avoid formal care and resort to self-care techniques, but little is known about the nature of these techniques, or more generally about the accuracy or breadth of this population's knowledge of SSTIs.

METHODS

Semi-structured qualitative interviews were conducted with 12 people who inject heroin in two metropolitan areas: Sacramento and Boston, USA.

RESULTS

These interviews reveal a robust and accurate knowledge base regarding skin infections, including the progression from simple cellulitis to an abscess, and acknowledgment of the possibility of serious infections. Nonetheless, there remains a reticence to seek care secondary to past traumatic experiences. A step-wise approach to self-care of SSTI infections was identified, which included themes of whole-body health, topical applications, use of non-prescribed antibiotics, and incision and drainage by non-medical providers.

CONCLUSIONS

The reported SSTI self-care strategies demonstrate resilience and ingenuity, but also raise serious concerns about inappropriate antibiotic consumption and complications of invasive surgical procedures performed without proper training, technique, or materials. Harm reduction agencies and health care providers should work to obviate the need for these potentially dangerous practices by improving healthcare access for this population. In the absence of robust solutions to meet the needs of this population, education materials should be developed to optimize the efficacy and minimize the harms of these practices, while empowering and supporting the autonomy of people who use drugs and providing clear guidance on when self-care should be abandoned in favor of formal medical care.

[Exanthema after travel abroad]

In view of globalization and the associated transport of goods as well as rising travel activity, imported infections with subtropical and tropical pathogens are increasing in Germany. In returning travelers presenting with fever, general symptoms and skin rash, a number of diseases need to be considered. The clinical appearance of the skin rash, accurate travel history and epidemiological information on country-specific risks are helpful in making the correct diagnosis. In this article we provide an overview of the most common exanthemas in travelers who have returned, associated symptoms, diagnostic methods, therapies, as well as prevention strategies.

Predictors of hospital readmission in United States adults with psoriasis

BACKGROUND

Previous studies showed a large inpatient burden of psoriasis in the United States. Less is known about the hospital readmission for psoriasis.

OBJECTIVES

To determine the patterns and predictors of hospital readmission rates for psoriasis.

METHODS

We analyzed data from the 2012-2014 Nationwide Readmissions Database, a representative sample of hospital readmissions in the United States.

RESULTS

Among 2606 admissions for psoriasis, 216 had ≥1 readmissions for psoriasis (prevalence [95% confidence interval]: 8.3% [6.6%-10.0%]) and 918 for all-causes (35.2% [32.2%-38.3%]). The mean annual cost of first readmission for any reason was $3,500,141, with $8,357,961 for subsequent readmissions. In multivariable regression models, readmission for psoriasis was associated with ≥6 day-long index hospitalization (adjusted hazard ratio [95% confidence interval]: 1.82 [1.06-3.12]), teaching hospital (1.93 [1.13-3.31]), comorbid skin infection (2.13 [1.11-4.08]), and hospitalization in the autumn (4.51 [2.54-8.00]), but inversely associated with other infections (0.49 [0.26-0.92]). Readmissions for psoriasis increased from 2012 to 2014 (1.93 [1.26-2.93]).

LIMITATIONS

No data on psoriasis characteristics.

CONCLUSION

Inpatients with psoriasis had high rates of readmission overall but low rates of readmission for psoriasis per se. A subset of psoriasis patients was hospitalized repeatedly and responsible for most inpatients costs. Future interventions are needed to lower readmission rates among psoriasis patients.

The ALT-70 cellulitis model maintains predictive value at 24 and 48 hours after presentation

BACKGROUND

Cellulitis has many potential mimickers, and its misdiagnosis often leads to unnecessary hospitalizations and higher health care costs. The ALT-70 predictive model offers an objective tool to help differentiate between cellulitis and other clinically similar conditions at the time of initial emergency department (ED) presentation.

OBJECTIVE

To evaluate the performance of the ALT-70 predictive model at 24 and 48 hours following ED presentation.

METHODS

We performed a retrospective review of our prior cohort and expanded our data collection to include data at 24 and 48 hours after initial ED presentation. We compared classification measures for the ALT-70 at the time of initial ED presentation, 24 hours after presentation, and 48 hours after presentation.

RESULTS

There was a statistically significant difference in median ALT-70 score between patients with true cellulitis and those with mimickers of cellulitis at all time points. Sensitivity, specificity, positive predictive value, and negative predictive value of the ALT-70 score was similar across all 3 time points.

LIMITATIONS

Single-center design may reduce generalizability.

CONCLUSION

At 24 and 48 hours, the ALT-70 performed similarly to the way it performed at the time of initial ED presentation, allowing for its use in a wider array of clinical settings.

Dermatologic manifestations in spaceflight: a review

With manned missions to Mars on the horizon, understanding and preparing for the medical conditions these astronauts might face becomes vital. According to the literature, the most commonly reported medical events in space are dermatological in nature. Dermatologic conditions rarely threaten an astronaut's life or the mission. However, manifestations and management of dermatologic events become an important consideration in anticipation of spaceflights to Mars and beyond. Given the limited number of articles written about dermatological conditions in this specific population, this review summarizes current knowledge related to dermatology in space. Overall, common dermatologic conditions found during spaceflight include viral reactivations, contact dermatitis or eczematous patches, and skin infections. Diagnosis and treatment can be difficult given the lack of resources in space as well as the hazards and side effects of certain treatments. In this review article we aim to summarize common skin changes induced by spaceflight, describe previously reported skin conditions including current treatment options, explore the risk of skin cancer in this unique population, and address the challenge of remote diagnosis.

Age-based health and economic burden of skin and soft tissue infections in the United States, 2000 and 2012

OBJECTIVE

The aim of this study was to compare the incidence of skin and soft tissue infections (SSTIs) across healthcare settings and analyze direct healthcare expenditures related to SSTIs in 2000 and 2012 in the United States.

METHODS

We performed a retrospective, cross-sectional analysis of nationally representative data from the Medical Expenditure Panel Surveys. Population-based incidence rates were examined for all healthcare settings that include inpatient visits, emergency department visits and ambulatory visits for SSTIs. The direct costs of healthcare services utilization were reported. Population-based prescribing rates for each antimicrobial class during ambulatory visits were compared.

RESULTS

A total of 2.4 million patients experienced an SSTI in 2000 compared to 3.3 million in 2012 (40% increase). From 2000 to 2012, the incidence of patients with at least one hospital visit for SSTIs increased 22%, ambulatory care visits increased 30%, and emergency department visits increased 40%. The incidence of SSTIs in children and adolescents declined 50% (from 150 to 76 per 10,000 person; RR = 0.51, 95% CI: 0.38-0.67; p<0.001) whereas SSTIs in older adults (> 65 years of age) increased almost 2-fold (from 67 to 130 per 10,000 person; RR = 1.94, 95% CI: 1.44-2.61; p<0.001). The annual incidence of SSTI in adults did not change significantly from 2000 to 2012 (from 84 to 81 per 10,000 person; RR = 0.96, 95% CI: 0.71-1.31; p = 0.41). The total estimated direct healthcare costs of SSTIs increased 3-fold from $4.8 billion in 2000 to $15.0 billion in 2012, largely driven by an 8-fold increase in ambulatory expenditures for SSTIs. Total population-based antimicrobial prescription rates for SSTIs increased 4-fold from 2000 to 2012 (from 59.5 to 250.4 per 10,000 person).

CONCLUSIONS

The highest healthcare utilization for SSTI treatment occurred in the ambulatory care setting and also accounted for the largest increase in overall direct expenditures from 2000 to 2012.

Relationship between maceration and wound healing on diabetic foot ulcers in Indonesia: a prospective study

The aim of this study was to clarify the relationship between maceration and wound healing. A prospective longitudinal design was used in this study. The wound condition determined the type of dressings used and the dressing change frequency. A total of 62 participants with diabetic foot ulcers (70 wounds) were divided into two groups: non-macerated (n = 52) and macerated wounds (n = 18). Each group was evaluated weekly using the Bates-Jensen Wound Assessment Tool, with follow-ups until week 4. The Mann-Whitney U test showed that the changes in the wound area in week 1 were faster in the non-macerated group than the macerated group (P = 0·02). The Pearson correlation analysis showed a moderate correlation between maceration and wound healing from enrolment until week 4 (P = 0·002). After week 4, the Kaplan-Meier analysis showed that the non-macerated wounds healed significantly faster than the macerated wounds (log-rank test = 19·378, P = 0·000). The Cox regression analysis confirmed that maceration was a significant and independent predictor of wound healing in this study (adjusted hazard ratio, 0·324; 95% CI, 0·131-0·799; P = 0·014). The results of this study demonstrated that there is a relationship between maceration and wound healing. Changes in the wound area can help predict the healing of wounds with maceration in clinical settings.

Common Skin Conditions in Children: Neonatal Skin Lesions

Skin findings during the initial month of life are ubiquitous. One study estimated that more than 95% of newborns have cutaneous findings, which often are distressing to parents but frequently are benign and self-limited. Among them are milia, cutis marmorata, congenital dermal melanocytosis, and the benign neonatal pustular eruptions (eg, benign cephalic pustulosis, erythema toxicum neonatorum, transient neonatal pustular melanosis). Clinicians need to recognize these benign skin conditions and differentiate them from more serious conditions, such as infectious pustular eruptions from bacterial, viral, and fungal causes, and inflammatory conditions, such as Langerhans cell histiocytosis. Notable bacterial pustular eruptions are bullous impetigo and congenital syphilis. Viral pustular dermatoses include neonatal herpes simplex virus infection and varicella zoster virus infection, which consists of congenital varicella syndrome, perinatal varicella, and infantile zoster. Fungal pustular eruptions include congenital and neonatal candidiasis. Seborrheic dermatitis is a self-limited condition that occurs with varying severity; symptomatic treatment is reserved for the more severe forms. Diaper dermatitis encompasses a broad clinical diagnosis, including allergic and irritant contact dermatitis, atopic dermatitis, infections, psoriasis, and other dermatologic conditions. Critical components of newborn skin care are immersion bathing, umbilical cord care, and use of emollients to augment skin barrier function.

Advances in the medical management of skin and soft tissue infections

Skin and soft tissue infections are some of the most common infectious disease diagnoses in both inpatient and outpatient settings. With bacterial resistance to antimicrobials growing, decision making on empiric antibiotics is becoming increasingly difficult. Additionally, the most recent guidance from a professional society on the treatment of skin and soft tissue infections was published in 2014 by the Infectious Diseases Society of America and is now two years old. New antimicrobial agents have been developed and approved for the treatment of skin and soft tissue infections since then, and more are in the pipeline. This review summarizes the evidence on treatments that are new or in development and the potential repurposing of old antimicrobials. The clinical utility of these treatments is also discussed.

Diagnosis and management of skin and soft tissue infections in the intensive care unit: a review

PURPOSE

To review the salient features of the diagnosis and management of the most common skin and soft tissue infections (SSTI). This review focuses on severe SSTIs that require care in an intensive care unit (ICU), including toxic shock syndrome, myonecrosis/gas gangrene, and necrotizing fasciitis.

METHODS

Guidelines, expert opinion, and local institutional policies were reviewed.

RESULTS

Severe SSTIs are common and their management complex due to regional variation in predominant pathogens and antimicrobial resistance patterns, as well as variations in host immune responses. Unique aspects of care for SSTIs in the ICU are discussed, including the role of prosthetic devices, risk factors for bacteremia, and the need for surgical consultation. SSTI mimetics, the role of dermatologic consultation, and the unique features of SSTIs in immunocompromised hosts are also described.

CONCLUSIONS

We provide recommendations for clinicians regarding optimal SSTI management in the ICU setting.

[Cutaneous infections in the emergency department : the devil in the detail]

Skin and soft tissue infections, which are a common cause of admission, are characterized by a clinical polymorphism leading to diagnostic errors. To a certain point, confusion exists between used terms and indicated treatment, especially since the emergence of methicillin-resistant Staphylococcus aureus (MRSA) infections.The paucity of cutaneous findings early in the course of deep soft tissue infections makes diagnosis challenging for physicians in charge. Some of these infections are warranted to achieve a lower mortality and morbidity by the administration of effective surgical treatment.

[The skin microbiota: a colossus steps into the spotlight]

The skin contains many commensal bacteria. For years, these microbes have been considered to be exploiters of the human host for nutrients. However, recent findings indicates that the skin microbiota is also used by the human host to protect himself against invading pathogens as the commensal bacteria have direct antimicrobial capacity and provide factors required to mount a protective immune responses in the skin. While the healthy skin microbiome functions as guardians of host defense, increased or decreased bacterial composition of the skin microbiome (called dysbiosis) leads to skin inflammation and disease. Here we will review the emerging data on the role of distinct types of dysbiosis in the pathogenesis skin diseases and illustrate how the new understanding of the role of the skin microbiome has implications in the clinical management of skin diseases.

[Skin and soft tissue infections (SSTIs)]

Skin and Soft Tissue Infections (SSTIs) encompass a wide spectrum of inflammatory diseases of the skin, subcutis, fascia and muscles. Recent national trends indicate increasing rates of patients treated for these diagnoses at outpatient surgical department, but also of patients hospitalized with severe forms of SSTIs. Up to 90% fatality rates are reported in the literature for the most severe forms, resulting from underestimation of initial symptoms and therefore delayed onset of radical therapy only the phase of septic shock. The paper provides an interdisciplinary review of essential principles of the diagnosis and therapy of SSTIs, reflecting present knowledge supported by evidence-based medicine.

The diabetic foot in 2015: an overview

In 2015, it can be said that the diabetic foot is no longer the Cinderella of diabetic complications. Thirty years ago there was little evidence-based research taking place on the diabetic foot, and there were no international meetings addressing this topic. Since then, the biennial Malvern Diabetic Foot meetings started in 1986, the American Diabetes Association founded their Foot Council in 1987, and the European Association for the Study of Diabetes established a Foot Study Group in 1998. The first International Symposium on the Diabetic Foot in The Netherlands was convened in 1991, and this was soon followed by the establishment of the International Working Group on the Diabetic Foot that has produced useful guidelines in several areas of investigation and the management of diabetic foot problems. There has been an exponential rise in publications on diabetic foot problems in high impact factor journals, and a comprehensive evidence-base now exists for many areas of treatment. Despite the extensive evidence available, it, unfortunately, remains difficult to demonstrate that most types of education are efficient in reducing the incidence of foot ulcers. However, there is evidence that education as part of a multi-disciplinary approach to diabetic foot ulceration plays a pivotal role in incidence reduction. With respect to treatment, strong evidence exists that offloading is the best modality for healing plantar neuropathic foot ulcers, and there is also evidence from two randomized controlled trials to support the use of negative-pressure wound therapy in complex post-surgical diabetic foot wounds. Hyperbaric oxygen therapy exhibits the same evidence level and strength of recommendation. International guidelines exist on the management of infection in the diabetic foot. Many randomized trials have been performed, and these have shown that the agents studied generally produced comparable results, with the exception of one study in which tigecycline was shown to be clinically inferior to ertapenem ± vancomycin. Similarly, there are numerous types of wound dressings that might be used in treatment and which have shown efficacy, but no single type (or brand) has shown superiority over others. Peripheral artery disease is another major contributory factor in the development of ulceration, and its presence is a strong predictor of non-healing and amputation. Despite the proliferation of endovascular procedures in addition to open revascularization, many patients continue to suffer from severely impaired perfusion and exhaust all treatment options. Finally, the question of the true aetiopathogenesis of Charcot neuroarthropathy remains enigmatic, although much work is currently being undertaken in this area. In this area, it is most important to remember that a clinically uninfected, warm, insensate foot in a diabetic patient should be considered as a Charcot foot until proven otherwise, and, as such, treated with offloading, preferably in a cast.

Effectiveness of interventions to enhance healing of chronic ulcers of the foot in diabetes: a systematic review

The outcome of management of diabetic foot ulcers remains a challenge, and there remains continuing uncertainty concerning optimal approaches to management. It is for these reasons that in 2008 and 2012, the International Working Group of the Diabetic Foot (IWGDF) working group on wound healing published systematic reviews of the evidence to inform protocols for routine care and to highlight areas, which should be considered for further study. The same working group has now updated this review by considering papers on the interventions to improve the healing of chronic ulcers published between June 2010 and June 2014. Methodological quality of selected studies was independently assessed by two reviewers using Scottish Intercollegiate Guidelines Network criteria. Selected studies fell into the following ten categories: sharp debridement and wound bed preparation with larvae or hydrotherapy; wound bed preparation using antiseptics, applications and dressing products; resection of the chronic wound; oxygen and other gases, compression or negative pressure therapy; products designed to correct aspects of wound biochemistry and cell biology associated with impaired wound healing; application of cells, including platelets and stem cells; bioengineered skin and skin grafts; electrical, electromagnetic, lasers, shockwaves and ultrasound and other systemic therapies, which did not fit in the aforementioned categories. Heterogeneity of studies prevented pooled analysis of results. Of the 2161 papers identified, 30 were selected for grading following full text review. The present report is an update of the earlier IWGDF systematic reviews, and the conclusion is similar: that with the possible exception of negative pressure wound therapy in post-operative wounds, there is little published evidence to justify the use of newer therapies. Analysis of the evidence continues to present difficulties in this field as controlled studies remain few and the majority continue to be of poor methodological quality.

Interventions in the management of infection in the foot in diabetes: a systematic review

The expert panel on diabetic foot infection (DFI) of the International Working Group on the Diabetic Foot conducted a systematic review seeking all published reports relating to any type of treatment for infection of the foot in persons with diabetes published as of 30 June 2014. This review, conducted with both PubMed and EMBASE, was used to update an earlier one undertaken on 30 June 2010 using the same search string. Eligible publications included those that had outcome measures reported for both a treated and a control population that were managed either at the same time, or as part of a before-and-after case design. We did not include studies that contained only information related to definition or diagnosis, but not treatment, of DFI. The current search identified just seven new articles meeting our criteria that were published since the 33 identified with the previous search, making a total of 40 articles from the world literature. The identified articles included 37 randomised controlled trials (RCTs) and three cohort studies with concurrent controls, and included studies on the use of surgical procedures, topical antiseptics, negative pressure wound therapy and hyperbaric oxygen. Among the studies were 15 RCTs that compared outcomes of treatment with new antibiotic preparations compared with a conventional therapy in the management of skin and soft tissue infection. In addition, 10 RCTs and 1 cohort study compared different treatments for osteomyelitis in the diabetic foot. Results of comparisons of different antibiotic regimens generally demonstrated that newly introduced antibiotic regimens appeared to be as effective as conventional therapy (and also more cost-effective in one study), but one study failed to demonstrate non-inferiority of a new antibiotic compared with that of a standard agent. Overall, the available literature was both limited in both the number of studies and the quality of their design. Thus, our systematic review revealed little evidence upon which to make recommendations for treatment of DFIs. There is a great need for further well-designed trials that will provide robust data upon which to make decisions about the most appropriate treatment of both skin and soft tissue infection and osteomyelitis in diabetic patients.

[Non-gonococcal infectious urethritis : pathogen spectrum and management]

For many years an increase in cases of urethritis has been observed in western Europe. In order to be able to combat this continuous rise, the perception of sexually transmitted diseases must be promoted, the clarification and screening must be intensified and therapy must be rapidly and correctly carried out. In addition to the commonest pathogens causing urethritis, namely chlamydia and gonococci, many other pathogenic microbes must be taken into consideration in the diagnostics. With respect to therapy, apart from the increasing resistance formation of Mycoplasma genitalium, the decreasing effectiveness of standard forms of treatment of other microbes must be emphasized. For chronic and recurrent urethritis in particular a broad clarification of the pathogen should be carried out to enable targeted treatment and also partner treatment. Priority must again be given to primary prevention.

Diabetes mellitus and infection: an evaluation of hospital utilization and management costs in the United States

AIMS

The objective of this study is to evaluate the number of diabetics that seek medical treatment in emergency departments or require hospitalization for infection management in the United States. This study also assesses the socioeconomic impact of inpatient infection management among diabetics.

METHODS

We accessed the Healthcare Cost and Utilization Project's Nationwide Emergency Department Sample database and the Nationwide Inpatient Sample database to perform a retrospective analysis on diabetics presenting to the emergency department or hospitalized for infection management from 2006 to 2011.

RESULTS

Emergency Department: Since 2006, nearly 10 million diabetics were annually evaluated in the emergency department. Infection was the primary reason for presentation in 10% of these visits. Among those visits, urinary tract infection was the most common infection, accounting for over 30% of emergency department encounters for infections. Other common infections included sepsis, skin and soft tissue infections, and pneumonia. Diabetics were more than twice as likely to be hospitalized for infection management than patients without diabetes. Hospitalization: Since 2006, nearly 6 million diabetics were annually hospitalized. 8-12% of these patients were hospitalized for infection management. In 2011, the inpatient care provided to patients with DM, and infection was responsible for over $48 billion dollars in aggregate hospital charges.

CONCLUSIONS

Diabetics commonly present to the emergency department and require hospitalization for infection management. The care provided to diabetics for infection management has a large economic impact on the United States healthcare system. More efforts are needed to develop cost-effective strategies for the prevention of infection in patients with diabetes.

Active immunization with an octa-valent Staphylococcus aureus antigen mixture in models of S. aureus bacteremia and skin infection in mice

Proteomic studies with different Staphylococcus aureus isolates have shown that the cell surface-exposed and secreted proteins IsaA, LytM, Nuc, the propeptide of Atl (pro-Atl) and four phenol-soluble modulins α (PSMα) are invariantly produced by this pathogen. Therefore the present study was aimed at investigating whether these proteins can be used for active immunization against S. aureus infection in mouse models of bacteremia and skin infection. To this end, recombinant His-tagged fusions of IsaA, LytM, Nuc and pro-Atl were isolated from Lactococcus lactis or Escherichia coli, while the PSMα1-4 peptides were chemically synthesized. Importantly, patients colonized by S. aureus showed significant immunoglobulin G (IgG) responses against all eight antigens. BALB/cBYJ mice were immunized subcutaneously with a mixture of the antigens at day one (5 μg each), and boosted twice (25 μg of each antigen) with 28 days interval. This resulted in high IgG responses against all antigens although the response against pro-Atl was around one log lower compared to the other antigens. Compared to placebo-immunized mice, immunization with the octa-valent antigen mixture did not reduce the S. aureus isolate P load in blood, lungs, spleen, liver, and kidneys in a bacteremia model in which the animals were challenged for 14 days with a primary load of 3 × 10⁵ CFU. Discomfort scores and animal survival rates over 14 days did not differ between immunized mice and placebo-immunized mice upon bacteremia with S. aureus USA300 (6 × 10⁵ CFU). In addition, this immunization did not reduce the S. aureus isolate P load in mice with skin infection. These results show that the target antigens are immunogenic in both humans and mice, but in the used animal models do not result in protection against S. aureus infection.

Dermatologic emergencies

Although dermatology may be regarded as a medical specialty with few emergencies, they do exist and range from primary cutaneous disorders to severe systemic conditions with skin manifestations. Prompt recognition for appropriate diagnosis and treatment often is necessary to improve a patient's prognosis and a single decision can mark the difference between life and death.

Effect of an electronic alert on treatment of skin and soft tissue infections

This is a prospective intervention study conducted between 2007 and 2011 to evaluate whether an electronic alert can influence provider practice in treatment of skin and soft tissue infections (SSTIs). A best-practice alert (BPA) was programmed to appear for intervention ICD-9 SSTI diagnoses. Controls were patients who had other SSTI ICD-9 codes where the BPA was not programmed to fire. Rate of culture taken in patients was compared between patients in the intervention and control groups. We found that cultures were taken among 13.5% of the intervention group and 5.4% of the control group (p <.0001). A logistic regression analysis controlling for covariates showed the odds of the intervention group having a culture taken was 2.6 times that of the control group. The results of this study support the use of BPAs for improving the management of SSTIs.

[Skin and soft tissue infections in children: consensus on diagnosis and treatment]

Skin and soft tissue infections are a common reason for consultation in primary health care centers. Data from the local epidemiology of these infections are rare, but Staphylococcus aureus and Streptococcus pyogenes are known to be the major etiologic agents. The appearance in recent years of community-originated strains of methicillin-resistant S. aureus and erythromycin-resistant pyogenes raises controversy in the choice of initial empirical treatment. This national consensus is for pediatricians, dermatologists, infectologists and other health professionals. It is about clinical management, especially the diagnosis and treatment of community-originated skin and soft tissue infections in immunocompetent patients under the age of 19.

Management of cutaneous abscesses by dermatologists

IMPORTANCE

There is currently no data detailing the degree to which dermatologists follow CDC/Infectious Diseases Society of America (IDSA) guidelines in the treatment of abscesses, which recommend that incision and drainage (I+D) as primary therapy for skin and soft tissue infections (SSTI).

OBJECTIVE

To evaluate the management of skin abscesses by dermatologists.

DESIGN, SETTING, PARTICIPANTS

A national email survey of 780 dermatologists was conducted from May-June 2012. Awareness, experience, and preparedness of respondents for abscess treatment, as well as the treatment practices in different clinical scenarios were evaluated. Response rate = 65% (n=510).

ELIGIBILITY CRITERIA

board certified/eligible dermatologists practicing in US. Main practice affiliation: solo (20%), group (33%), university health system/academic (32%), multi-specialty (13%), and other (2%). Main practice setting: urban (49%), suburban (42%), and rural (9%).

MAIN OUTCOME AND MEASURES

Practitioner report of: awareness of national guidelines, use of I+D in initial management of uncomplicated abscess found on face, trunk, and extremity on patients age 6 months, 3, 15, 50, and 80 years, and use of antibiotics in the initial management.

RESULTS

99% of respondents were capable of performing I+D in their practice. The IDSA recommends cultures in all patients treated with antibiotic therapy, and does not recommend antibiotics for the treatment of simple abscess. 18% of respondents reported culturing abscesses less than 50% of the time, while 91% incorporated antibiotics into initial treatment. Nearly a quarter (24%) of respondents would choose an initial antibiotic that would not cover Methicillin-resistant Staphylococcus aureus (MRSA). For facial abscesses, as the age of the patient increased from infant, respondents were more likely to incorporate I+D into their initial treatment. For abscesses on the trunk and extremities, respondents were less likely to I+D infants and toddlers, compared to adolescents, adults and the elderly.

CONCLUSION

Although most dermatologists were prepared to manage uncomplicated abscesses (98%), this survey identifies gaps in clinical standards of care established by the CDC/IDSA. Identification of these practice gaps may impact physician practice and dermatology residency curricula, and may serve to improve abscess management and antibacterial stewardship in the outpatient setting.

New and emerging vaccination strategies for prevention and treatment of dermatological diseases

Accelerated by the rapid advancements of our understanding of the molecular and cellular pathology of diseases and of the components and mechanisms of cellular and humoral immune responses, new vaccination strategies are being developed and explored for treatment and prevention of infectious diseases, cancer, autoimmune disorders and allergies. Many newly developed vaccination strategies are already in clinical trials, some with very promising results. Although most of these strategies are still at very early stages of their development, it is foreseeable that vaccination will evolve to play an important role in prevention, treatment and management of all the above classes of diseases.

Infective skin conditions in an adult sea-going population

Infective skin conditions represent a significant element of the caseload for sea-going and shore-side clinicians. They are common within the wider military setting due to the frequent requirement to live in close proximity to others in conditions which favour the spread of skin and soft tissue infections (SSTI). Within the UK civilian population, 24% of individuals see their family doctor for skin conditions each year, accounting for 13 million primary care consultations annually. Of these, almost 900,000 were referred to dermatologists in England in 2009-2010 and resulted in 2.74 million secondary care consultations. Several recent articles have highlighted the problem of Panton-Valentine Leukocidin Staphylococcus aureus (PVL-SA) infection and carriage in sailors on submarines, and soldiers deployed to Afghanistan. However, the majority of published articles relate to land-based military personnel. This article aims to provide an overview of the most common infective skin conditions presenting among Naval personnel (based on the authors' experience), illustrated by several case studies, together with an approach to their diagnosis and management.

Allogeneic blood and bone marrow cells for the treatment of severe epidermolysis bullosa: repair of the extracellular matrix

Contrary to the prevailing professional opinion of the past few decades, recent experimental and clinical data support the fact that protein replacement therapy by allogeneic blood and marrow transplantation is not limited to freely diffusible molecules such as enzymes, but also large structural proteins such as collagens. A prime example is the cross-correction of type VII collagen deficiency in generalised severe recessive dystrophic epidermolysis bullosa, in which blood and marrow transplantation can attenuate the mucocutaneous manifestations of the disease and improve patients' quality of life. Although allogeneic blood and marrow transplantation can improve the integrity of the skin and mucous membranes, today's accomplishments are only the first steps on the long pathway to cure. Future strategies will be built on the lessons learned from these first transplant studies.

Management of skin infections in Pacific children prior to hospitalisation

INTRODUCTION

Hospital admissions for childhood skin infections in New Zealand (NZ) are on the increase. Pacific children make up a high number of those who are admitted. This study describes the parents of Pacific children's understanding and management of skin sores in the home prior to the sores becoming infected and requiring hospital admission.

METHODS

A descriptive qualitative approach combined with the Pacific research frameworks of Fa'afaletui and the Metaphor of Kakala were used to elicit parents' understanding and management of children's skin sores in the home. The semi-structured interviews were conducted in English or Samoan, and all transcribed into English.

FINDINGS

Mothers of 11 Pacific children admitted with skin infections between 2006 and 2008 were interviewed. The children's infections started with insect bites in some cases. Parents actively sought treatment to ensure children's optimal health was maintained. Initial management included a 'watch and see' approach for some, until deterioration was noted.

CONCLUSION

This is the first known study in New Zealand that has captured children's experiences when sustaining a skin infection/s and the activities that took place while seeking treatment in the community. Although most of the children received medical attention in primary health care (PHC), this did not prevent the need for hospital admission. The acuteness and seriousness of children's health on admission shows that preventive efforts need to increase and the early management of infections in PHC settings needs to be better understood.

Dermatologic manifestation of diabetes

With the rising incidence of diabetes mellitus (DM) in the US, it is of paramount importance that practitioners understand the complications of DM and how best to manage them. Diabetes affects every organ system and the skin is no exception. There are numerous cutaneous manifestations of DM that have similar etiologies and result from the same pathologic mechanisms as the internal complications of this disease state. In addition, skin manifestations may precede the diagnosis of diabetes. The present article reviews both the common and less common cutaneous manifestations of DM, including presenting lesions, pathogenesis, and management.

[Skin barrier defects in atopic dermatitis: new treatments?]

Atopic dermatitis (AD) is a chronic inflammatory skin disorder and the most frequent skin disease in children. Skin barrier defects play a crucial role in its pathogenesis. 50% of patients suffering from AD present mutations in the filaggrin gene, coding for a key protein of the upper layer of the skin. However these mutations alone are not sufficient for disease development, suggesting that environmental factors are also of great importance in the genesis of AD. In particular skin infections frequently provoke clinical exacerbations in patients suffering from AD. New insights into skin barrier dysfunctions have facilitated the development of drugs targeting the sustainable restitution of the skin's physiologic function. These agents could modify the pharmacological approach of AD treatments in the future.

Advances in tropical diseases

There are six diseases that WHO considers as the major threat in developing countries, leprosy, filariasis, malaria, schistosomiasis, Chagas disease and leishmaniasis; and of these only malaria does not present skin lesions. These diseases are among the so called tropical diseases found in countries of tropical climate, usually infections and infestations considered exotic and rare in European and North American countries. It is extremely important for doctors of all countries to be able to provide correct pre travel counseling and to make early diagnosis and treatment, thus avoiding dissemination of these dieases to non endemic areas. The authors review some important tropical diseases seen in Brazil, as paracoccidiodomycosis, lobomycosis, myiasis, tungiasis, and cutaneous schistosomiasis and discuss new information about them.

[Infection, wounds and local treatments]

Infection is the result of complex interactions between bacteria, the host, treatments and the wound environment. The clinical signs and the diagnosis can be obvious, subclinical or relate to an intermediary situation rather than a confirmed infection. Suitable local treatments do not automatically involve the use of antibacterial drugs and consist in washing and draining the wound with appropriate dressings. The local treatment of the infected wound is set to develop further in order to be more effective with regard to both the biofilm as well as the circulating bacteria.

Cutaneous infestations and infections

Cutaneous infections and infestations are common problems in childhood and adolescence. This article provides an update focusing on the diagnosis and management of several frequently encountered infections and infestations: scabies, bedbugs, head lice, tinea capitis, and tinea versicolor.

Flexural and extensoral eruptions in dermatologic disease

Dermatologic eruptions can be generalized or localized to specific areas of the body. Eruptions in specific body regions may suggest specific diagnosis. Recognizing such clinical patterns can facilitate the identification of the underlying pathology. In this contribution, we shall discuss those dermatologic lesions that tend to affect the flexure and extensor surfaces.

[ALEA study. Treatment of chronic wounds infected by the application of silver dressings nanocrystalline combined with dressings hydrocellular]

OBJECTIVE

This study was conducted with the objective to assess, in real clinical conditions in primary care and geriatric centers, application and utility of nanocrystalline silver dressings dressings combined with hydrocellular in relation to the development during 20 shifts dressing or complete healing of the characteristics of the lesions included in the study

MATERIAL AND METHODS

Prospective observational multicenter open, repeated measures. It could include injuries of different etiologies (pressure ulcers stage 11-111, lower limb and traumatic wounds or surgical origin), with clinical signs of local infection (at least three of the following: redness, purulent discharge, heat, edema and pain). Only one wound was included per patient. An analysis of effectiveness by intention to treat all lesions included.

RESULTS

We recruited 103 patients who met the inclusion criteria but were collected in which 77 patients were used for nanocrystalline silver dressings in some phase of the study, They had a median of 80 years of age and 58.4% were women. By type of injury: 53.2% pressure ulcers, 31.2% lower extremity ulcers and 14.3% traumatic or surgical wounds. Over 50% of the lesions was older than eight months and a larger area of 22.75 cm2. At first, 70.1% had redness, purulent discharge 64.9%, 37.7% heat edema 42.9% and 65.8% pain. Remained in the study a median of 42.5 days at a rate of change of dressing every 2.5. During this time in 96.1% of the lesions were removed for clinical signs of local infection in a statistically significant (p < or = 0.001). 27.3% healed from injuries and those not healed, 92.9% experienced improvement, and its healing curves were statistically significant (p < 0.05). 92.2% of clinicians assessed treatment with these products as good or excellent.

CONCLUSION

The use of the products used in this study consistent with the concept and PLH TIME, has proved useful in this type of injury reducing the clinical signs of infection, promoting granulation tissue and necrotic removing the burden being able to manage the exudate of an optimal healing and getting one out of three masses.

[New directions of hypertermic surgery in experiment]

Mechanisms of influence of thermal stream towards living biological tissues were studied. Bacteriological investigations of infected, purulent wounds before and after their thermostream processing were conducted. There was substantiated the possibility of the method usage for sanation of subfascial massively infected purulent wounds.
