    Treatment of Acne Keloidalis Nuchae: A Systematic Review of the Literature.
    Dermatol Ther (Heidelb) 2016 Sep 18;6(3):363-78. Epub 2016 Jul 18.
    Department of Dermatology and Cutaneous Surgery, University of Miami Miller School of Medicine, Miami, FL, USA.
    Acne keloidalis nuchae (AKN) is a chronic inflammatory condition that leads to fibrotic plaques, papules and alopecia on the occiput and/or nape of the neck. Traditional medical management focuses on prevention, utilization of oral and topical antibiotics, and intralesional steroids in order to decrease inflammation and secondary infections. Unfortunately, therapy may require months of treatment to achieve incomplete results and recurrences are common. Read More

    Cephalosporin-Induced Toxic Epidermal Necrolysis Treated with Intravenous Immunoglobulin.
    Cureus 2015 Oct 21;7(10):e359. Epub 2015 Oct 21.
    Infectious Disease, Nassau University Medical Center.
    Toxic epidermal necrolysis (TEN) is a life-threatening cutaneous reaction to various medications, including antipsychotics and antibiotics. While cephalosporin-induced TEN is very rare, we present a case of cefepime-induced TEN. There are several commonly used therapies for TEN, including immunosuppressive agents and intravenous immunoglobulin (IVIG), but their true efficacy has not been proven. Read More

    TNF-α: a treatment target or cause of sarcoidosis?
    J Eur Acad Dermatol Venereol 2015 Nov 26;29(11):2104-11. Epub 2015 Aug 26.
    Department of Dermatology and Allergology, Philipps University, Marburg, Germany.
    Sarcoidosis is a systemic granulomatous disease that affects numerous organs, commonly manifesting at the lungs and skin. While corticosteroids remain the first line of treatment, tumour necrosis factor alpha (TNF-α) inhibitors have been investigated as one potential steroid sparing treatment for sarcoidosis. TNF-α is one of many components involved in the formation of granulomas in sarcoidosis. 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

    Selective decontamination of the digestive tract ameliorates severe burn-induced insulin resistance in rats.

    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.
    Faculté de Médecine, Université Paris-Est Créteil, Créteil, France; Institut Mondor de Recherche Biomédicale (IMRB), INSERM U 955, Créteil, France; AP-HP, Groupe Hospitalier Henri-Mondor Albert-Chenevier, CIC-BT-504, Créteil, France.
    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

    Role of hyperbaric medicine for intractable leg ulcers: a case report.
    J Wound Care 2014 Oct;23(10 Suppl):S18-22
    Minneapolis Heart Institute; Minneapolis Heart Institute Research Foundation; 920 E 28th Street, Minneapolis MN 55449.
    We present a case report of intractable multifactorial leg ulcer that was treated successfully with multiple approaches including hyperbaric oxygen treatment (HBOT) to prepare for skin grafting. A 66-year-old female with a history of rheumatoid arthritis and Felty's syndrome presented with a non-healing ulcer on her left leg that was caused by a trauma. She failed multiple treatment options including debridement, different wound dressings, antibiotics, anti-inflammatories and vein closure procedure. 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

    A recent case of periorbital necrotizing fasciitis--presentation to definitive reconstruction within an in-theater combat hospital setting.
    J Oral Maxillofac Surg 2014 Jul 14;72(7):1320-4. Epub 2014 Feb 14.
    Department Head, Department of Trauma and General Surgery, Role III Multinational Medical Unit, Kandahar, Afghanistan, Plastic and Reconstructive Surgery Service, Walter Reed National Military Medical Center, Bethesda, MD, Adjunct Assistant Professor, University of Pittsburgh Medical Center, Pittsburgh, PA, Adjunct Assistant Professor, the Johns Hopkins University School of Medicine, Baltimore, MD, Assistant Professor, The Uniformed Services University of the Health Sciences, Bethesda, MD. Electronic address:
    First described in 1924, necrotizing fasciitis (NF) is a rapidly progressing, severe suppurative infection of the superficial fascia, often associated with vascular thrombosis and necrosis of the overlying skin. Despite advances in medical therapy, the mortality remains high, with rates exceeding 25 to 50% in some studies. Early diagnosis and treatment is paramount in the management of this serious infection and should include wide surgical debridement and drainage of all necrotic tissues, coupled with aggressive parenteral antibiotics.

    Hidradenitis suppurativa: A practical review of possible medical treatments based on over 350 hidradenitis patients.
    Dermatol Online J 2013 Apr 15;19(4). Epub 2013 Apr 15.
    Weil Cornell Medical College, New York, NY.
    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

    Sorafenib induces autophagy in human myeloid dendritic cells and prolongs survival of skin allografts.
    Transplantation 2013 Mar;95(6):791-800
    Graduate Institute of Clinical Medicine, College of Medicine, Taipei Medical University, Taipei, Taiwan.
    Background: Sorafenib, a multikinase inhibitor approved for the treatment of advanced renal cell carcinoma and hepatocellular carcinoma, has been reported inhibitory on the function of dendritic cells. This study was aimed to determine the effects of sorafenib on inducing autophagy and immunomodulatory activity and its implication on graft rejection.

    Methods: Cell viability and surface antigens were examined by 7-amino-actinomycin D and flow cytometric analysis. 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

    Emerging dilemmas with methicillin-resistant Staphylococcus aureus infections in children.
    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.
    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.

    [Periorbital necrotizing fasciitis: a complication of a dacryocystorhinostomy].
    J Fr Ophtalmol 2011 Apr 15;34(4):258.e1-5. Epub 2011 Mar 15.
    Service d'ophtalmologie, centre hospitalier régional de la Citadelle, 1, boulevard du 12(e) de Ligne, 4000 Liège, Belgique.
    We report a rare case of periorbital necrotizing fasciitis following a dacryocystorhinostomy procedure. We describe the common features of this rare infection of the skin and subcutaneous tissues and discuss the different management strategies as well as the controversial role of anti-inflammatory medication in treating this condition.

    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

    Clofazimine inhibits human Kv1.3 potassium channel by perturbing calcium oscillation in T lymphocytes.

    Department of Pharmacology and Molecular Sciences, The Johns Hopkins University School of Medicine, Baltimore, Maryland, United States of America.
    The Kv1.3 potassium channel plays an essential role in effector memory T cells and has been implicated in several important autoimmune diseases including multiple sclerosis, psoriasis and type 1 diabetes. A number of potent small molecule inhibitors of Kv1. 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. Read More

    Totect: a new agent for treating anthracycline extravasation.
    Clin J Oncol Nurs 2007 Jun;11(3):387-95
    Anthracycline chemotherapy agents bind to DNA and cause cell death when they extravasate into healthy tissue. Although many approaches to managing extravasations have been studied and reported, data from two prospective clinical trials suggest that Totect (dexrazoxane for injection, TopoTarget USA, Inc.) is an effective anthracycline extravasation treatment.

    Conversion to everolimus in a patient with arterial hypertension and recurrent cutaneous neoplasia--a case report.
    Nephrol Dial Transplant 2006 Jul;21 Suppl 3:iii38-41
    Servicio de Nefrologia, Hospital Ramón y Cajal, Carretera de Colmenar, Km9.100, 28034 Madrid, Spain.
    Calcineurin inhibitors (CNIs) are frequently associated with side effects such as nephrotoxicity and hypertension, so CNI withdrawal from immunosuppressive regimens is desirable in certain cases. The proliferation signal inhibitors/mammalian target of rapamycin inhibitors everolimus and sirolimus may play an important role in achieving CNI withdrawal. Studies on sirolimus have shown that conversion from CNIs is associated with improvements in renal function and hypertension. Read More

    Necrotizing fasciitis--the importance of early diagnosis and debridement.
    AORN J 2005 Dec;82(6):1031-40
    Hutchinson Medical Center, Kan, USA.
    Necrotizing fasciitis (NF) is a potentially life-threatening bacterial infection of the skin, deep subcutaneous tissue, and fascia. Early symptoms may be misdiagnosed as cellulitis. A hallmark symptom that distinguishes NF from cellulitis is severe local pain that is out of proportion to the size and type of the wound present. Read More

    Aspects of constitutive and acquired antibioresistance in Aeromonas hydrophila strains isolated from water sources.
    Roum Arch Microbiol Immunol 2003 Jul-Dec;62(3-4):179-89
    1 - NIRDMI "Cantacuzino ", Bucharest, 2 - Fetesti-District Sanitary Center, Romania.
    Over the last three decades, the literature pointed out the implications of Aeromonas species in human pathology. These species were described as being involved in intestinal (several outbreaks of acute gastroenteritis of choleric/dysenteric form or chronic diarrhoea, ulcerative colitis, etc.) in normal adults or children, as well as in extraintestinal infections in immunocompromised hosts.

    Health care-associated infections in the neonatal intensive care unit.
    Am J Infect Control 2005 Jun;33(5):268-75
    Ohio State University and Columbus Children's Hospital, 700 Children's Drive, Columbus, OH 43205, USA.
    Neonates represent a unique and highly vulnerable patient population. Advances in medical technology that have occurred over the last few decades have improved the survival and quality of life for neonates, particularly those infants born with extreme prematurity or with congenital defects. Although immunologic immaturity and altered cutaneous barriers play some role in the vulnerability of neonates to nosocomial infections, clearly, therapeutic interventions that have proven to be lifesaving for these fragile infants also appear to be associated with the majority of infectious complications resulting in neonatal morbidity and mortality.

    Valdecoxib-associated acute generalized exanthematous pustulosis.
    Burns 2005 May;31(3):383-7
    Department of Surgery, North Carolina Jaycee Burn Center CB# 7600, University of North Carolina Hospitals, 101 Manning Drive, Chapel Hill, NC 27514, USA.
    AGEP (acute generalized exanthematous pustulosis) is a relatively rare exfoliative skin syndrome consisting of generalized eruption of pustules in response to medication or infection. Because AGEP may have other systemic manifestations, such as renal failure, hyperthermia, lab abnormalities, and/or hemodynamic instability, it is important to make the distinction between AGEP and other life-threatening generalized skin diseases, such as toxic epidermal necrolysis (TEN). Here we present a case of AGEP in response to valdecoxib, which has not previously been described in the literature. Read More

    Active role of chimerism in transplantation tolerance induced by antilymphocyte serum, sirolimus, and bone-marrow-cell infusion.

    Different costimulatory and growth factor requirements for CD4+ and CD8+ T cell-mediated rejection.
    J Immunol 2004 Jul;173(1):214-21
    Department of Medicine, Harvard Medical School, Boston, MA 02215, USA.
    Costimulatory signals and growth factor signals play a key role in commanding T cell activation and T cell effector function. However, how costimulatory signals and growth factor signals interact and integrate into the activation program of CD4(+) and CD8(+) T cells during the allograft response remains poorly defined. In the present study we found that either CD4- or CD8-deficient mice can vigorously reject the skin allografts. Read More

    Antibiotic prophylaxis in clean surgery: clean non-implant wounds.
    J Chemother 2001 Nov;13 Spec No 1(1):96-101
    Professorial Unit of Surgery, North Tees General Hospital, Stockton-on-Tees, Cleveland, UK.
    Wound infection after clean surgery (the majority being hernia, varicose vein and breast surgery) is often greatly underestimated. If a trained and blinded observer is involved using close and prolonged surveillance to at least 30 days postoperatively with appropriate definitions or wound scores, an infection rate of up to 15% or more may be found. Equally controversial is the value of prophylactic antibiotics in preventing postoperative wound infection; there is no clear cut evidence of efficacy and some random controlled trials (RCTs) have shown no differences at all.

    Purpose: Chronic renal allograft nephropathy is associated with both immune and ischemic injury which may act synergistically to promote an inflammatory response. The immunosuppressant mycophenolic acid and the polyphenolic agents curcumin and quercetin possess properties that might ameliorate such injury. We studied the effects of these agents in models of ischemic renal injury and skin allograft rejection. Read More

    Introduction: Angiosarcomas are rare, aggressive tumors of vascular origin, most commonly affecting older males. An optimum treatment strategy has not yet been defined.

    Case Report: We report on a 68-year-old male patient who initially presented with a small, bruise-like macule of the cheek. Read More

    Preliminary study on HA coating percutaneously implanted in bone.
    Int J Artif Organs 1999 Oct;22(10):713-8
    Institute of Materials Science and Technology, Sichuan University, Chengdu, China.
    A comparative investigation on the possibility of hydroxyapatite (HA) coating and pure Ti column to form biological sealing with skin tissue was completed in this study. HA coating and pure Ti column were percutaneously implanted in the tibia of rabbits. Compared with titanium (Ti) implant, HA coating forms epithelial sealing with skin tissue at 6 weeks postoperatively, while the Ti implant may loosen from the implanted site and be lost. Read More

    Artificial nutritional support in patients with gastrointestinal fistulas.

    Gastrointestinal (GI) fistulas allow abnormal diversions of GI contents, digestive juices, water, electrolytes, and nutrients from one hollow viscus to another or to the skin, potentially precipitating a wide variety of pathophysiologic effects. Mortality rates have decreased significantly during the past few decades from as high as 40% to 65% to 5.3% to 21. Read More

    Wound care after cutaneous surgery can play an integral role in wound healing. Wound care regimens have changed dramatically over the last 35 years as the physiology of wound healing has become better understood. Foremost is the improvement in wound healing achieved by keeping the wound occluded and moist. Read More

    Effect of mizoribine on effector T cell-mediated immune responses in mice.
    Biol Pharm Bull 1996 Sep;19(9):1136-40
    Department of Pharmacology, Gifu Pharmaceutical University, Japan.
    T cells play a principal role in cellular immunity and govern the regulatory mechanism in humoral immunity. Therefore, T cells play a key role as either effectors or regulators in the immune network. Mizoribine (MZR), an immunosuppressive agent, suppresses both humoral and cellular immunity by acting on both T cells and B cells. Read More
