Trichogranuloma in a Hairdresser with Systemic Sclerosis.

Cureus 2018 May 25;10(5):e2690. Epub 2018 May 25.

Wolfson Diabetes and Endocrine Clinic, Institute of Metabolic Science, Addenbrooke's Hospital, Cambridge University Hospitals Nhs Foundation Trust, Cambridge, Uk.

Trichogranuloma is a rare occupational disease of hairdressers that develops when hair clippings penetrate the skin and cause a foreign-body reaction. We describe a case of a hairdresser with limited cutaneous systemic sclerosis who developed a chronic felon on her right third finger and received repeated courses of antibiotics without improvement. An occupational history and awareness of occupational diseases in hairdressers led to the correct diagnosis of trichogranuloma. Read More

Gut microbes contribute to variation in solid organ transplant outcomes in mice.

Microbiome 2018 05 25;6(1):96. Epub 2018 May 25.

Department of Medicine, The University of Chicago, Chicago, USA.

Background: Solid organ transplant recipients show heterogeneity in the occurrence and timing of acute rejection episodes. Understanding the factors responsible for such variability in patient outcomes may lead to improved diagnostic and therapeutic approaches. Rejection kinetics of transplanted organs mainly depends on the extent of genetic disparities between donor and recipient, but a role for environmental factors is emerging. Read More

Cutaneous squamous cell carcinoma: Management of advanced and high-stage tumors.

J Am Acad Dermatol 2018 02;78(2):249-261

Department of Dermatology, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts.

While the majority of cutaneous squamous cell carcinomas (cSCCs) can be treated surgically, the additional work-up and treatments indicated for high-risk cSCC remain undefined. In recent years, improvements in tumor staging systems have allowed for the more accurate stratification of tumors into high- and low-risk categories. This insight, along with the publication of cSCC guidelines, brings us closer to the development of a consensus approach. Read More

AGEs Induced Autophagy Impairs Cutaneous Wound Healing via Stimulating Macrophage Polarization to M1 in Diabetes.

Sci Rep 2016 11 2;6:36416. Epub 2016 Nov 2.

Department of Burns and Plastic Surgery, Shanghai Ninth People's Hospital, Institute of Traumatic Medicine; Shanghai Jiao Tong University School of Medicine, Shanghai, 201900, China.

Autophagy is essential in physiological and pathological processes, however, the role of autophagy in cutaneous wound healing and the underlying molecular mechanism remain elusive. We hypothesized that autophagy plays an important role in regulating wound healing. Here, we show that enhanced autophagy negatively impacts on normal cutaneous healing process and is related to chronic wounds as demonstrated by the increased LC3 in diabetic mice skin or patients' chronic wounds.

Regulatory T cell expressed MyD88 is critical for prolongation of allograft survival.

Transpl Int 2016 Aug 14;29(8):930-40. Epub 2016 Jun 14.

Center for Transplantation Science, Department of Surgery, Harvard Medical School, Massachusetts General Hospital, Boston, MA, USA.

MyD88 signaling directly promotes T-cell survival and is required for optimal T-cell responses to pathogens. To examine the role of T-cell-intrinsic MyD88 signals in transplantation, we studied mice with targeted T-cell-specific MyD88 deletion. Contrary to expectations, we found that these mice were relatively resistant to prolongation of graft survival with anti-CD154 plus rapamycin in a class II-mismatched system. Read More

Use of negative pressure wound therapy with instillation in the management of cervical necrotizing fasciitis.

Head Neck 2015 Nov 6;37(11):E157-60. Epub 2015 Aug 6.

University Hospitals Case Medical Center, Otolaryngology - Head and Neck Surgery, Cleveland, Ohio.

Background: Cervical necrotizing fasciitis is an aggressive infection that can be rapidly fatal if aggressive therapies are not initiated early. Negative pressure wound therapy has been established as an effective tool in promoting wound healing, but its use in the acutely infected wound has been avoided because it limits frequent irrigations and standard dressing changes.

Methods: We discuss a novel application of negative pressure wound therapy with instillation in an immunocompromised patient with extensive cervical necrotizing fasciitis. Read More

Administration of low doses of IL-2 combined to rapamycin promotes allogeneic skin graft survival in mice.

Am J Transplant 2014 Dec 13;14(12):2874-82. Epub 2014 Nov 13.

Human CD4(+) CD25(+) FoxP3(+) regulatory T cells (Tregs) prevent allogeneic graft rejection by inhibiting T cell activation, as has been shown in mouse models. Recently, low-dose IL-2 administration was shown to specifically activate Tregs but not pathogenic conventional T cells, leading to resolution of type 1 diabetes in nonobese diabetic mice. We therefore tested the ability of low-dose IL-2 to prevent allogeneic skin graft rejection. Read More

Clinical and microbiological aspects of biofilm-associated surgical site infections.

Adv Exp Med Biol 2015 ;830:47-67

Department of Surgery, Medical College of Wisconsin, Milwaukee, WI, USA,

While microbial biofilms have been recognized as being ubiquitous in nature for the past 40 years, it has only been within the past 20 years that clinical practitioners have realized that biofilm play a significant role in both device-related and tissue-based infections. The global impact of surgical site infections (SSIs) is monumental and as many as 80 % of these infections may involve a microbial biofilm. Recent studies suggest that biofilm- producing organisms play a significant role in persistent skin and soft tissue wound infections in the postoperative surgical patient population. Read More

Guiding postablative lymphocyte reconstitution as a route toward transplantation tolerance.

Am J Transplant 2014 Jul 19;14(7):1678-89. Epub 2014 May 19.

Sir William Dunn School of Pathology, University of Oxford, Oxford, UK.

Anti-lymphocyte-depleting antibodies have increasingly been utilized in the clinic as induction therapy aiming to improve transplantation outcomes by reducing the need for long-term immunosuppression. However, maintenance immunosuppression is still required as lymphocyte reconstitution through homeostatic proliferation, partially driven by IL-7, continues to replenish tolerance-refractory immune cells capable of rejection. In murine models of MHC mismatched skin grafting, we investigated whether it is feasible to control the lymphocyte reconstitution process to delay rejection and favor tolerance processes. Read More

Hidradenitis suppurativa (HS), a pathological follicular disease, impacts patients' lives profoundly. HS most commonly involves cutaneous intertriginous areas, such as the axilla, inner thighs, groin and buttocks, and pendulous breasts, but can appear on any follicular skin. Protean, HS manifests with variations of abscesses, folliculitis, pyogenic granulomas, scars (oval honeycombed), comedones, tracts, fistulas, and keloids. Read More

'Stalled' periocular necrotising fasciitis: early effective treatment or host genetic determinants?

Eye (Lond) 2013 Mar 15;27(3):432-7. Epub 2013 Feb 15.

Orbital Unit, Moorfields Eye Hospital, London, UK.

Background: Necrotising fasciitis (NF) is a devastating disease with considerable mortality and morbidity, and early aggressive surgical debridement of devitalised necrotic tissues has traditionally been advocated.

Methods: We describe three patients who were referred from other units several weeks after developing periocular necrotising fasciitis; in all the three, the disease had been managed medically without surgical debridement, with apparent 'stalling' of the inflammatory process despite persistent necrotic periocular tissue.

Results: Following 'elective debridement' of the devitalised tissues and reconstruction with local flaps, all achieved a satisfactory aesthetic result. Read More

Keratitis, ichthyosis, and deafness syndrome: a review of infectious and neoplastic complications.

J Am Acad Dermatol 2013 Jul 4;69(1):127-34. Epub 2013 Feb 4.

Department of Dermatology, University of California, San Francisco, School of Medicine, San Francisco, California 94115, USA.

Keratitis, ichthyosis, and deafness (KID) syndrome is a rare genodermatosis associated with mutations in the connexin 26 gene. Although characterized by this clinical triad, KID syndrome predisposes to a heterogeneous spectrum of cutaneous manifestations and complications, both infectious and neoplastic in nature. Chronic mucocutaneous candidiasis and/or superinfection of skin lesions commonly occur and warrant aggressive therapeutic intervention. Read More

Effect of CD200 and CD200R1 expression within tissue grafts on increased graft survival in allogeneic recipients.

Immunol Lett 2013 Jan 21;149(1-2):1-8. Epub 2012 Nov 21.

The Toronto Hospital, University Health Network, Toronto, Canada.

In transgenic mice over-expressing CD200 (CD200(tg)) graft survival is associated with increased intra-graft expression of mRNAs for genes associated with altered T cell subset differentiation (Foxp3; TGFβ; IL-10). Grafts are rejected in recipients lacking the inhibitory receptor for CD200, CD200R1. We compared grafts of C57BL/6 skin taken from control, CD200KO, CD200(tg), CD200R1KO or CD200(tg). Read More

Curr Opin Otolaryngol Head Neck Surg 2011 Dec;19(6):462-6

Department of Otolaryngology/Head and Neck Surgery, Louisiana State University Health Sciences Center, New Orleans, LA 70112, USA.

Purpose Of Review: There has been an increase in the incidence of methicillin-resistant Staphylococcus aureus (MRSA) infections in recent years. This article reviews the literature on three manifestations of MRSA infections in the head and neck of children: sinonasal infections, otologic infections, and neck abscesses.

Recent Findings: Historically nosocomial in origin, MRSA infections more recently are found to occur in otherwise healthy patients with no obvious risk factors. Read More

Antibiotic resistance: an editorial review with recommendations.

Authors:
Ted Rosen

J Drugs Dermatol 2011 Jul;10(7):724-33

Baylor College of Medicine, Houston, TX 77030, USA.

Within a relatively short period of time after the first antimicrobial drugs were introduced, bacteria began exhibiting varying degrees of resistance. The excessive use (and abuse) of antibiotics in agriculture, and in both human and veterinary medicine, has played a critical causative role in the development of antibiotic resistance, which is now recognized as a global public health threat. Increasing concern over this issue should impact the practice of cutaneous medicine and surgery, as dermatologists can easily adopt new healthcare delivery patterns that might reduce the development of antibiotic resistance and still achieve acceptable treatment outcomes.

Limiting the amount and duration of antigen exposure during priming increases memory T cell requirement for costimulation during recall.

J Immunol 2011 Feb 21;186(4):2033-41. Epub 2011 Jan 21.

Department of Surgery and Emory Transplant Center, Emory University, Atlanta, GA 30322, USA.

Donor-reactive memory T cells (Tmem) can play an important role in mediating graft rejection after transplantation. Transplant recipients acquire donor-reactive Tmem not only through prior sensitization with alloantigens but also through previous exposure to environmental pathogens that are cross-reactive with allogeneic peptide-MHC complexes. Current dogma suggests that most, if not all, Tmem responses are independent of the requirement for CD28 and/or CD154/CD40-mediated costimulation to mount a recall response. Read More

Electrochemotherapy treatment of a recalcitrant earlobe keloid scar with chronic lymphocytic leukaemia infiltration.

J Plast Reconstr Aesthet Surg 2010 Oct 2;63(10):e733-6. Epub 2010 Jun 2.

Department of Plastic & Reconstructive Surgery, James Cook University Hospital, Middlesbrough, UK.

Electrochemotherapy, a tumour ablation modality, which facilitates intracellular delivery of poorly-permeable cytotoxic drugs, such as bleomycin, has shown promising results in the treatment of cutaneous and subcutaneous melanomatous and non-melanomatous metastases. We report the case of a 52-year-old Caucasian gentleman with a keloid scar to his left earlobe that developed following a piercing. Despite multiple intralesional steroidal injections, five intralesional excisions and a course of superficial radiotherapy the keloid scar remained over nine years later. Read More

Antibacterial prophylaxis in dermatologic surgery: an evidence-based review.

Am J Clin Dermatol 2010 ;11(1):35-44

Skin Cancer Department, Bond University, Belmont, Victoria, Australia.

Clean, non-contaminated skin surgery is associated with low rates of surgical site infection (SSI), bacterial endocarditis, and joint prosthesis infection. Hence, antibacterial prophylaxis, which may be associated with adverse effects, the emergence of multidrug-resistant pathogens, and anaphylaxis, is generally not recommended in dermatologic surgery. Some body sites and surgical reconstructive procedures are associated with higher infection rates, and guidelines for SSI antibacterial prophylaxis have been proposed for these cases. Read More

Department of Internal Medicine, University of Leipzig, Liebigstr. 20, Leipzig, Germany, 04103.

Background: Hepatocellular carcinoma (HCC) is the fifth most common global cancer. When HCC is detected early, interventions such as percutaneous ethanol injection (PEI), percutaneous acetic acid injection (PAI), and radiofrequency thermal ablation (RFTA) have curative potential and represent low invasive alternatives to surgery. The role of PEI or PAI has not been addressed in a systematic review. Read More

Surgical management of diabetic foot infections and amputations.

AORN J 2008 May;87(5):935-46; quiz 947-50

Department of Orthopaedics, Podiatry Division, University of Texas Health Science Center, San Antonio, TX, USA.

The incidence of diabetes with severe foot infections (eg, necrotizing fasciitis, gas gangrene, ascending cellulitis, infection with systemic toxicity or metabolic instability) has risen significantly during the past decade. Foot infections are a major cause of hospitalization and subsequent lower extremity amputation among patients with diabetes mellitus who have a history of a preexisting ulceration. Surgical management often is required to address severe diabetic foot infections because they can be limb- or life-threatening. Read More

Primary cutaneous zygomycosis in an immunodeficient infant: a case report and review of the literature.

Ann Plast Surg 2008 Apr;60(4):433-6

Department of Surgery, University of California Davis, Sacramento, California, USA.

We report a case of primary cutaneous zygomycosis caused by Rhizopus species in an infant with a hematological malignancy. Multiple surgical debridements, skin grafting, and intravenous antifungal therapy were necessary to ultimately eradicate the infection. Zygomycotic infections are an emerging concern in immunocompromised patients because of their increased incidence as well as their potential to cause substantial morbidity through both emotional distress and impaired functionality.

Microscopic and physiologic evidence for biofilm-associated wound colonization in vivo.

Wound Repair Regen 2008 Jan-Feb;16(1):23-9

Department of Dermatology and Cutaneous Surgery, University of Miami Miller School of Medicine, Miami, FL 33136, USA.

A biofilm is a collection of microbial cells that are attached to a surface and embedded in a self-produced extrapolymeric substance. The understanding of the biofilm phenotype is important in the understanding of bacteria in vitro but it has been difficult to translate biofilm science to the clinical setting. More recently, preliminary criteria for defining biofilm associated diseases have been proposed and the purpose of this study was to create a biofilm-associated wound model based on these criteria.
