Objective: To explore the clinical effects of repair of wounds in the fingers after electrical burn with wrist perforator free flaps. Methods: Twelve patients (13 fingers) with electrical burn were hospitalized in our burn ward from January 2016 to January 2017. After radical debridement, the size of wounds ranged from 5.0 cm×2.0 cm to 10.0 cm×7.0 cm. Wounds with size below or equal to 6.0 cm ×2.5 cm were repaired with free flaps based on the superficial palmar branch of radial artery, with flap area ranging from 2...

A 13-yr-old male addax (Addax nasomaculatus) presented with locally extensive alopecia, slight erythema, and skin thickening on the medial aspect of the left rear leg between the stifle and tarsus. Cutaneous T-cell lymphoma was diagnosed after histopathology and immunohistochemical staining of representative skin-punch biopsies. No treatment was elected, and the addax was euthanized 3 yr later because of poor body condition, chronic dental disease, and confirmed spread of lymphoma to other cutaneous locations...

Interleukin-4 (IL-4)-induced T helper (Th) 2 cells promote susceptibility to the protozoan parasite Leishmania major, while conferring immunity to the intestinal trematode Schistosoma mansoni Here, we report that abrogation of IL-4 receptor alpha (IL-4Rα) signaling on B cells in BALB/c mice (mb1(cre)IL-4Rα(-/lox)) transformed nonhealer BALB/c to a healer phenotype with an early type 1 and dramatically reduced type 2 immune response and an absence of ulceration and necrosis during cutaneous leishmaniasis. From adoptive reconstitution and mixed bone-marrow chimera studies in B cell-deficient (µMT) mice, we reveal a central role for B cell-derived IL-4 and IL-4Rα in the optimal induction of the susceptible type 2 phenotype to L...

BACKGROUND: Skin infections account for 40% of emergency visits in pediatric dermatology. It is important to promptly recognize skin infections with potential complications and initiate treatment. However some characteristic skin findings may imitate skin infections and are often misdiagnosed. OBJECTIVES: To illustrate frequent pediatric skin infections and pitfalls in view of imitators and differential diagnoses. MATERIALS AND METHODS: A photo quiz is presented with the discussion of a selection of acute pediatric skin infections in comparison to their infectious or noninfectious differential diagnoses...

An odontogenic cutaneous fistula is a pathological communication between the outer skin surface of the face and the oral cavity. Facial cutaneous fistula is a complication of odontogenic infection that is often misdiagnosed with skin infection. We report a rare case, which was diagnosed as basal cell carcinoma based on the biopsy of skin lesions in the patient who had been diagnosed with odontogenic cutaneous fistula. A 64-year-old male patient presented with a cutaneous odontogenic fistula. The patient had undergone surgical extraction of fistula tract and loose tooth before dermatology or plastic surgery consultation...

Mycobacterium chelonae is a rapidly growing mycobacterium found in water and soil that can cause local cutaneous infections in immunocompetent hosts but more frequently affects immunocompromised patients. Typically, patients will present with painful subcutaneous nodules of the joints or soft tissues from traumatic inoculation. However, exhibiting a sporotrichoid-like pattern of these nodules is uncommon. Herein, we report a case of sporotrichoid-like distribution of cutaneous Mycobacterium chelonae in a patient with systemic lupus erythematosus on significant immunosuppressive medications...

A cutaneous infection with Alternaria spp. was diagnosed in a 2-year-old male intact Irish setter dog, presenting with multifocal papules, plaques and ulcerations involving all four distal limbs, shoulder blades, scrotum, pinnae and nasal mucous membranes. The dog had been treated for inflammatory bowel disease and lymphangiectasia with immunosuppressive doses of cyclosporine and prednisolone for approximately 3 months. The diagnosis was based on clinical signs, the demonstration of fungal elements within skin biopsies, deep fungal culture and fungal PCR from a formalin-fixed tissue specimen...

Invasive fungal infections (IFIs) are a significant cause of morbidity in solid organ transplant (SOT) recipients. Common causes among them are Aspergillus, Candida, and Cryptococcus. Antifungal prophylaxis has led to decrease in overall incidence of IFI; however, there is very little decline in the incidence of Cryptococcal infections of SOT recipients because effective prophylaxis is not available against this infectious agent. Spectrum of manifestation of Cryptococcal infection varies in immunocompetent and immunocompromised host with subclinical and self-limiting with lungs being the primary site in immunocompetent and central nervous system as the most common site in an immunocompromised host...

REVIEW
Jack Sunter, Keith Gull
The shape and form of protozoan parasites are inextricably linked to their pathogenicity. The evolutionary pressure associated with establishing and maintaining an infection and transmission to vector or host has shaped parasite morphology. However, there is not a 'one size fits all' morphological solution to these different pressures, and parasites exhibit a range of different morphologies, reflecting the diversity of their complex life cycles. In this review, we will focus on the shape and form of Leishmania spp...

Bacillary angiomatosis (BA) is an angioproliferative disease of immunocompromised patients that usually presents as vascular tumors in the skin and subcutaneous tissues. It is caused by chronic infections with either Bartonella henselae or B. quintana. Oral cavity BA is exceedingly rare and even rarer without simultaneous cutaneous disease. We report herein the case of a 51-year-old HIV-infected man who presented severe odynophagia and an eroded lesion on the hard palate that progressed to an oronasal fistula...

BACKGROUND: Cutaneous leishmaniasis (CL) generally presents with a single or several localised cutaneous ulcers without involvement of mucous membranes. Ulcerated lesions are susceptible to secondary contamination that may slow the healing process. OBJECTIVE: This study verified the influence of non-parasitic wound infection on wound closure (epithelialisation) and total healing. METHODS: Twenty-five patients with a confirmed diagnosis of CL and ulcerated lesions underwent biopsy of ulcer borders...

AIMS: Our proposal was to develop a vaccine based on total Leishmania antigens (TLA) adjuvanted with polyinosinic-polycytidylic acid [Poly(I:C)] able to induce a Th1 response which can provide protection against Leishmania infection. METHODS AND RESULTS: Mice were vaccinated with two doses of TLA-Poly(I:C) administered by subcutaneous route at three week interval. Humoral and cellular immune responses induced by the immunization were measured. The protective efficacy of the vaccine was evaluated by challenging mice with infective promastigotes of Leishmania (Leishmania) amazonensis into the footpad...

We recently reported that the open-mesh (0.7 μ) polyacrylamide microparticles (MPs) with internally-coupled Cibacron affinity dye demonstrate protective effect in mice challenged into footpads with high doses (200 LD50) of anthrax (Sterne) spores. A single injection of MPs before spore challenge reduces inflammatory response, delays onset of mortality and promotes survival. In this study, we show that the effect of MPs was substantially increased at the lower spore dose (7 LD50). The inflammation of footpads was reduced to the background level, and 60% of animals survived for 16 days while all untreated infected animals died within 6 days with strong inflammation...

Significance: Skin serves as a protective barrier for mammals. Epidermal stem cells are responsible for maintaining skin homeostasis. When cutaneous injuries occur, skin homeostasis and integrity are damaged, leading to dire consequences such as acute, chronic, or infected wounds. Skin wound healing is an intrinsic self-saving chain reaction, which is crucial to facilitating the replacement of damaged or lost tissue. Recent Advances: An immense amount of research has uncovered the underlying mechanisms behind the complex and highly regulated wound healing process...

Hand, foot and mouth disease (HFMD) and herpangina (HA) are common childhood diseases mostly associated with human enteroviruses (EV). Although usually benign illnesses, neurological complications may be observed during large epidemics when enterovirus A71 (EV-A71) is involved, as observed in the Asia Pacific Region and in China since the late 1990s. The occurrence of these complications warrants reinforcing the surveillance of the emergence of EV-A71 infections in France and Europe. Monitoring EV infections associated with HFMD can be considered as an effective tool to detect an upsurge of EV-A71 infections in a timely manner...
