The treatment of leishmaniasis still relies on drugs with potentially serious adverse effects. Herein, we tested a topical formulation of bacterial cellulose (BC) membranes containing Diethyldithiocarbamate (DETC), a superoxide dismutase 1 inhibitor. Leishmania-infected macrophages exposed to BC-DETC resulted in parasite killing, without pronounced toxic effects to host cells. This outcome was associated with lower SOD1 activity and higher production of superoxide and cytokine mediators. Topical application of BC-DETC significantly decreased lesion size, parasite load and the inflammatory response at the infection site, as well as the production of both IFN-γ and TNF...

A 17-year-old female patient affected by systemic lupus erythematosus (SLE) (who had been taking 300 mg/die of hydroxychloroquine for 3 years), Graves' disease (treated with 10 mg/die of tapazole), and celiac disease came to our attention for urticarial vasculitis. She had been taking prednisone (25 mg/die) for 3 days, and her blood tests showed high levels of Mycoplasma pneumoniae IgM and IgG antibodies. The association between urticaria and M. pneumoniae infections can be present in up to 7% of the cases and, to the best of our knowledge, only two reports of urticarial vasculitis and M...

INTRODUCTION: Wipple disease (WD) is a rare chronic disease caused by the bacillus Tropheryma whipplei. Constitutive, rheumatologic, gastrointestinal, cardiac, cerebral, lymphatic, cutaneous, and ophthalmological signs are possible systemic symptoms. However, thrombotic manifestations are rarely described as "stroke-like syndrome" or arterial thrombosis. Diagnosis is based on clinical manifestations and pathological examination. Laboratory findings may include anemia, leukocytosis, and thrombocytosis...

OBJECTIVE: STIs are the most common infections among adults. Concurrently, pubic hair grooming is prevalent. Small-scale studies have demonstrated a relationship between pubic hair grooming and STIs. We aim to examine this relationship in a large sample of men and women. DESIGN: We conducted a probability survey of US residents aged 18-65 years. The survey ascertained self-reported pubic hair grooming practices, sexual behaviours and STI history. We defined extreme grooming as removal of all pubic hair more than 11 times per year and high-frequency grooming as daily/weekly trimming...

BACKGROUND: Infestation of wounds with the larvae of Callophorid flies is relatively common in countries where these parasites are found. The most common species associated with infections in Southeast Asia is Chrysomya bezziana (Ch. bezziana), the Old World screw worm. Treatment consists of either subcutaneous injection of ivermectin or oral administration of nitenpyram combined with aggressive tissue debridement under general anaesthesia. OBJECTIVES: To describe the treatment of cutaneous myiasis in three dogs caused by the larvae of Ch...

Scopulariopsis brevicaulis onychomycosis with local cutaneous invasion was diagnosed in an acute leukemia patient and unsuccessfully treated with high-dose micafungin, based on antifungal susceptibility testing. This case should alert clinicians to the possible severe evolution of onychomycosis in neutropenic patients and suggests that surgery should be preferred in such a situation.

Mycobacterium abscessus is a pathogenic, rapidly growing mycobacterium responsible for pulmonary and cutaneous infections in immunocompetent patients and in patients with Mendelian disorders, such as cystic fibrosis (CF). Mycobacterium abscessus is known to transition from a smooth (S) morphotype with cell surface-associated glycopeptidolipids (GPL) to a rough (R) morphotype lacking GPL. Herein, we show that M. abscessus S and R variants are able to grow inside macrophages and are present in morphologically distinct phagosomes...

Neutrophils constitute essential players in inflammatory responses and are the first line of defence against harmful stimuli. However, dysregulation of neutrophil homeostasis can result in excessive inflammation and subsequent tissue damage. Neutrophilic dermatoses are a spectrum of inflammatory disorders characterized by skin lesions resulting from a neutrophil-rich inflammatory infiltrate in the absence of infection. The exact molecular pathophysiology of neutrophilic dermatoses has long been poorly understood...

Bacterial mycetoma is a neglected disease mainly observed in tropical area countries and typically associated with rural conditions, making its presence in developed countries of temperate climate areas rare. However, we report the first case of an autochthonous mycetoma case in continental France that originated from a new Nocardia species. A Gram-positive filamentous bacterium (OFN 14.177(T)) was isolated from a pus sample from the mycetoma of a male French patient 92 years old suffering from chronic lymphocytic leukemia...

OBJECTIVE: Alloplastic aortic graft infection is a devastating complication following aortic surgery. It is associated with excessively high mortality and morbidity caused by anastomotic rupture or septicemia. Many authors consider in situ replacement after complete surgical graft removal as the method of choice. However, there is an ongoing debate about the most suitable material for reconstruction. We present our first experiences with replacing the descending and infra-renal aorta using custom-made bovine pericardium grafts...

Vascular complications of intravesical instillation of bacillus Calmette-Guérin (BCG) are rare. BCG is an attenuated strain of Mycobacterium bovis (M. Bovis) that was initially developed for vaccination against tuberculosis, but it has also been used as an adjuvant treatment for bladder transitional carcinoma. We report a patient with a history of instillation of BCG two years before, who underwent surgical treatment of 2 pseudoaneurysms. The first, located in the left superficial femoral artery (SFA), was resected and the artery was ligated because he had a history of femoropopliteal occlusion...

Malaria and leishmaniasis are among the two most important health problems of many developing countries especially in the Middle East and North Africa. It is common for vector-borne infectious diseases to have similar hotspots which may be attributed to the overlapping ecological distribution of the vector. Hotspot analyses were conducted to simultaneously detect the location of local hotspots and test their statistical significance. Spatial scan statistics were used to detect and test hotspots of malaria and cutaneous leishmaniasis (CL) in Afghanistan in 2009...

BACKGROUND: Treatment of lacrimal sac abscess of the traditional surgical approach may result in complications from cutaneous fistula formation, damage the sac, cause skin scarring and even have the potential for inducing cicatricial ectropion. We designed a new treatment scheme that is expected to achieve internal drainage with the use of lacrimal probe and crawford silicon tube. METHODS: A prospective study was performed for the management of lacrimal sac abscesses...

RATIONALE: Lupus panniculitis (LP) is a unique variant of cutaneous lupus erythematosus. Clinical manifestations are typically mild and include erythema, nodules, and small ulcers. In certain cases, diagnosing LP may be challenging. Skin overlying the typical subcutaneous inflammation may appear normal, and bacterial superinfections of the skin sometimes mask the underlying LP. It has been suggested that a computed tomography (CT) scan may help to identify obscure LP lesions. Here, we report a case of a 54-year-old woman with an unusually severe form of LP, in which the full disease extent was only revealed by a fluorodeoxyglucose positron emission tomography (FDG-PET)/CT scan...

Corynebacterium diphtheriae is typically recognized as a colonizer of the upper respiratory tract (respiratory diphtheria) and the skin (cutaneous diphtheria). However, different strains of Corynebacteriumdiphtheriae can also cause invasive infections. In this study, the characterization of a non-toxigenic Corynebacteriumdiphtheriae strain (designated BR-INCA5015) isolated from osteomyelitis in the frontal bone of a patient with adenoid cystic carcinoma was performed. Pathogenic properties of the strain BR-INCA5015 were tested in a Caenorhabditis elegans survival assay showing strong colonization and killing by this strain...

Data on cutaneous HPV seroprevalence is primarily derived from skin cancer case-controls studies. Few studies have reported the seroprevalence of cutaneous HPV among healthy men. This study investigated the seroprevalence of cutaneous HPV types and associated risk factors among men residing in Brazil, Mexico, and the United States. Six hundred men were randomly selected from the HPV Infection in Men (HIM) Study. Archived serum specimens were tested for antibodies against 14 cutaneous HPV genotypes, β-HPV types (5/8/12/14/17/22/23/24/38/48), α-HPV 27, γ-HPV 4, µ-HPV1 and ν-HPV 41 using a GST L1-based multiplex serology assay...

Blue spot disease, believed to be caused by esocid herpesvirus 1 (EsHV1), has been observed in wild northern pike Esox lucius in a number of cold-water locations, including the northern USA, Canada, and Ireland. In the spring of 2014, a northern pike was caught in Wisconsin displaying the characteristic bluish-white circular plaques on the dorsum and fins. Microscopic examination of hematoxylin and eosin-stained sections of the proliferative cutaneous lesions revealed a focally extensive abundance of panepidermal, megalocytic keratinocytes with karyomegaly...
