    Functional constitutive nitric oxide synthase (NOS) is required for full expression of reflex cutaneous vasodilation that is attenuated in aged skin. Both the essential cofactor tetrahydrobiopterin (BH4) and adequate substrate concentrations are necessary for the functional synthesis of nitric oxide (NO) through NOS, both of which are reduced in aged vasculature through increased oxidant stress and upregulated arginase, respectively. We hypothesized that acute local BH4 administration or argi...

    Perioperative optimization of spatially resolved near-infrared spectroscopy determined cerebral frontal lobe oxygenation (scO2) may reduce postoperative morbidity. Norepinephrine is routinely administered to maintain cerebral perfusion pressure and, thereby, cerebral blood flow, but norepinephrine...... reduces the scO2.

    Nitric oxide (NO) increases cutaneous blood flow; however, the underpinning mechanism(s) remains to be elucidated. We hypothesized that the cutaneous blood flow response during intradermal administration of sodium nitroprusside (SNP, a NO donor) is regulated by calcium-activated potassium (KCa) channels and cyclooxygenase (COX) in young adults. We also hypothesized that these contributions are diminished in older adults given that aging can downregulate KCa channels and reduce COX-derived vasodilator prostanoids. In 10 young (23 ± 5 yr) and 10 older (54 ± 4 yr) adults, cutaneous vascular conductance (CVC) was measured at four forearm skin sites infused with 1) Ringer (Control), 2) 50 mM tetraethylammonium (TEA), a nonspecific KCa channel blocker, 3) 10 mM ketorolac, a nonspecific COX inhibitor, or 4) 50 mM TEA + 10 mM ketorolac via intradermal microdialysis. All skin sites were coinfused with incremental doses of SNP (0.005, 0.05, 0.5, 5, and 50 mM each for 25 min). During SNP administration, CVC was similar at the ketorolac site (0.005-50 mM, all P > 0.05) relative to Control, but lower at the TEA and TEA + ketorolac sites (0.005-0.05 mM, all P 0.05). Furthermore, TEA alone did not modulate CVC during any concentration of SNP administration in older adults (all P > 0.05). We show that during low-dose NO administration (e.g., 0.005-0.05 mM), KCa channels contribute to cutaneous blood flow regulation in young adults; however, in older adults, COX inhibition increases cutaneous blood flow through a KCa channel-dependent mechanism.

    The aim of this work is to develop and characterize a formulation intended for the cutaneous administration of glutathione (γ-glutamylcysteinylglycine, GSH), potentially useful for cellular defense against UV-induced damage. For this purpose, liposomes containing GSH or GSH/cyclodextrins(CDs) inclusion complexes as well as liposomes dispersed within a hydrophilic gel, were evaluated. These formulations were designed in order to obtain a system combining the advantages of liposomes as vehicles for topical drug delivery with those of CDs as penetration enhancers. The studied CDs were the natural (β-CD) and chemically modified (i.e., HP-β-CD and CH3 -β-CD) cyclodextrins. The prepared liposomes showed homogeneous size distribution, mean diameter in the range 622-1435 nm, small positive charge (+3.1 to +6.6 mV), and encapsulation efficiency of the peptide in the range 13.6%-23.7%. Release studies showed that the presence of the oligosaccharide may influence to some extent the amount of drug released, whereas stability studies clearly point out that the incorporation in a hydrophilic gel of 2-hydroxyethylcellulose insures a stable formulation maintaining unchanged the characteristics of liposomal vesicles.

    Cutaneous zygomycosis is a fungal infection caused by zygomycetes that affects the skin. It occurs in uncontrolled diabetic patients and immunosuppressed individuals. It has 2 clinical forms: primary cutaneous zygomycosis and secondary cutaneous zygomycosis. The first is characterized by necrotic lesions and the fungus is usually inoculated by trauma. If diagnosed early, it generally has a good prognosis. Secondary zygomycosis is usually a complication and extension of the rhinocerebral variety that starts as a palpebral fistula and progresses to a necrotic lesion with a poor prognosis. The diagnosis is made by identification of the fungus by direct KOH examination, culture, and biopsy. Treatment for the primary disease is surgical debridement plus amphotericin B. The secondary type is treated with amphotericin B and/or posaconazole.

    Full Text Available Leishmaniasis is used to describe a spectrum of diseases caused by the parasitic protozoa leishmania spp. and transmitted by infected female sandflies. There are three main forms of the disease; cutaneous, mucocutaneous, and visceral. According to the World Health Organization, almost 12 million people from 98 countries worldwide are currently infected with leishmaniasis, while 350 million people are at risk. It was reported that 2 million new cases are diagnosed every year, with three-fourth are cutaneous leishmaniasis (CL cases. The scientific and medical communities have learnt a lot about CL during the 20th and early 21st centuries. However, the management and control of the disease remains a difficult task. This article was focused on the most common form of the disease, cutaneous leishmaniasis, and especially its epidemiological aspects and treatment.

    Sarcoidosis is a multi-organ granulomatous disorder of unknown cause. Skin sarcoidosis occurs in about 25% of patients with systemic disease and may also arise in isolation. A wide range of clinical presentations of cutaneous sarcoidosis is recognised. The diagnosis rests on the presence of non-caseating granulomas on skin biopsy and the exclusion of other granulomatous skin disease. The treatment and overall prognosis of cutaneous sarcoidosis is primarily dependent on the degree of systemic involvement. In patients with aggressive disease limited to the skin immunosuppressive therapy may be indicated.

R aged of 41, without known pathological background presented for 20 days a nodular lesion of the anterior face of the neck, 2 juxtaposed ulcerated nodular lesions of the left wrist. He presented also subcutaneous nodules ranged linearly and extended to the root of the penis. Theses lesions were covered by an erythematous or ulcerated skin. The smear made from the genital lesions of the penis confirmed the diagnosis of a cutaneous leishmaniasis. The evolution was favourable after a 21 days treatment by doxycyclin after an interval of one week. Our observation was specific by the localisation of the cutaneous leishmaniasis and by the clinical form. This shows that in our region cutaneous leishmaniasis is characterised by different clinical symptoms. PMID:16425718

    1985-11-01

    Cutaneous histiocytosis may take two principal forms. It is either a benign proliferative process or a relentless, progressive process with a poor prognosis. In histiocytic medullary reticulosis, histiocytes demonstrate nuclear atypia and the outcome is uniformly fatal. Benign cephalic histiocytosis X causes lesions similar to those of histiocytosis X, but Langerhans' cells are absent. In congenital self-healing histiocytosis X, the Letterer-Siwe-like cutaneous infiltrate contains Langerhans' cells, but the lesions heal spontaneously without treatment. The nodular cutaneous lesions of juvenile xanthogranuloma appear in infancy and resolve without treatment; however, the higher percentage (10%) of associated ocular lesions may lead to glaucoma and blindness. In histiocytosis X, the cutaneous lesions show a marked proliferation of Langerhans' cells, with prognosis dependent on the patient's age and the extent of organ dysfunction. Patients who survive the acute form of the disease may develop diabetes insipidus, growth retardation, pulmonary fibrosis, and biliary cirrhosis. A subtle immunologic defect has been identified in patients with histiocytosis X, yet the pathogenesis of the disease is still speculative. Familial disease occurring in early infancy should be differentiated from complete or partial immunodeficiency syndromes. Guidelines for evaluating patients with cutaneous histiocytosis are reviewed.

Early diagnosis by deep cutaneous ulcer biopsy is most important for prognosis. Here, dermatologists play a significant role although treatment usually needs an interdisciplinary approach. Surgical procedures had been the cornerstone of treatment in the past including parathyroidectomy, but recently new medical treatments emerged aiming to normalize disturbances of minerals to reduce the serum concentration of sodium phosphate and to prevent precipitation and calcification.

    It is important for dermatologists to be aware of cutaneous changes related to religious practices to help in their recognition and management. The anatomic location of cutaneous lesions associated with friction from praying varies based on religious practice. Allergic contact dermatitis from products and substances commonly used in worshipping also vary by religion. Some religious practices may render individuals prone to infections that manifest on the skin. Tattoos of godly figures also may adorn the body. Religious practices also have been implicated in cases of urticaria, köbnerization, and leukoderma.

    Multifocal cutaneous histiocytic lesions were recognized in 9 dogs. Clinically, the dogs had multiple erythematous plaques or nodules in the skin (1 to 5 cm diameter). Histologically, the lesions were comprised of dermal or pannicular infiltrates of large histiocytic cells, with varying numbers of other inflammatory cells intermixed. By electron microscopy, the cells resembled those of canine cutaneous histiocytoma. The lesions seemed to wax and wane and appeared in new sites, regardless of treatment. The dogs ranged in age from 2 to 13 years; 7 dogs were under 6 years of age. Both sexes and various breeds were represented. An infectious agent could not be identified.

    Life-threatening and benign drug reactions occur frequently in the skin, affecting 8 % of the general population and 2-3 % of all hospitalized patients, emphasizing the need for physicians to effectively recognize and manage patients with drug-induced eruptions. Neurologic medications represent a vast array of drug classes with cutaneous side effects. Approximately 7 % of the United States (US) adult population is affected by adult-onset neurological disorders, reflecting a large number of patients on neurologic drug therapies. This review elucidates the cutaneous reactions associated with medications approved by the US Food and Drug Administration (FDA) to treat the following neurologic pathologies: Alzheimer disease, amyotrophic lateral sclerosis, epilepsy, Huntington disease, migraine, multiple sclerosis, Parkinson disease, and pseudobulbar affect. A search of the literature was performed using the specific FDA-approved drug or drug classes in combination with the terms 'dermatologic,' 'cutaneous,' 'skin,' or 'rash.' Both PubMed and the Cochrane Database of Systematic Reviews were utilized, with side effects ranging from those cited in randomized controlled trials to case reports. It behooves neurologists, dermatologists, and primary care physicians to be aware of the recorded cutaneous adverse reactions and their severity for proper management and potential need to withdraw the offending medication.

    2016-09-01

    Malignant melanoma is a rare disease in Asians but potentially the most aggressive form of skin cancer worldwide. It can occur in any melanocyte-containing anatomic site. Four main cutaneous melanoma subtypes are recognized: lentigo maligna melanoma, superficial spreading melanoma, acral lentiginous melanoma (ALM), and nodular melanoma. Generally, excessive exposure to ultraviolet (UV) radiation increases the risk of melanoma. The exception is ALM, which is the most common melanoma subtype in Asians and is not associated with UV radiation. ALM presents as dark brownish to black, irregular maculopatches, nodules, or ulcers on the palms, soles, and nails. The lesions may be misdiagnosed as more benign lesions, such as warts, ulcers, hematomas, foreign bodies, or fungal infections, especially in amelanotic acral melanomas where black pigments are absent. The aim of this brief review is to improve understanding and the rate of early detection thereby reducing mortality, especially regarding cutaneous melanoma in Asians. PMID:27689028

    2015-01-01

    Full Text Available Optimum healing of a cutaneous wound involves a well-orchestrated cascade of biological and molecular processes involving cell migration, proliferation, extracellular matrix deposition, and remodelling. When the normal biological process fails for any reason, this healing process can stall resulting in chronic wounds. Wounds are a growing clinical burden on healthcare systems and with an aging population as well as increasing incidences of obesity and diabetes, this problem is set to increase. Cell therapies may be the solution. A range of cell based approaches have begun to cross the rift from bench to bedside and the supporting data suggests that the appropriate administration of stem cells can accelerate wound healing. This review examines the main cell types explored for cutaneous wound healing with a focus on clinical use. The literature overwhelmingly suggests that cell therapies can help to heal cutaneous wounds when used appropriately but we are at risk of clinical use outpacing the evidence. There is a need, now more than ever, for standardised methods of cell characterisation and delivery, as well as randomised clinical trials.

    2001-07-01

    Multiple cutaneous xanthomas, associated with fasting hyperlipidaemia, are described in a 9-month-old domestic long-haired cat. A severely pruritic, papular, and crusting dermatitis affecting the head and neck, initially diagnosed as lesions of the eosinophilic granuloma complex, progressively developed on the head and pinnae. Pruritus was controlled with administration of prednisolone and chlorambucil. Repeat histological examination confirmed the diagnosis of cutaneous xanthoma and concurrent mild demodicosis. Marked fasting hypercholesterolaemia, hypertriglyceridaemia and transient hyperglycaemia were subsequently confirmed. Treatment for hyperlipidaemia and xanthomas with a low-fat diet (Hill's Feline r/d) and the previously unreported treatment for feline demodicosis of daily oral milbemycin were commenced. Multiple pink, alopecic plaques and papules gradually regressed, however pruritus recurred if immunosuppressive treatment was reduced, and well-demarcated areas of alopecia developed on the head, limbs and trunk, despite negative skin scrapings for demodex mites. Fungal culture of hair samples yielded Microsporum canis. All cutaneous lesions resolved with the addition of griseofulvin to the treatment regimen. Concurrent corneal ulceration and keratoconjunctivitis sicca ultimately resolved with treatment, including topical cyclosporin. Diabetes mellitus developed 6 months after resolution of skin lesions. No cutaneous or ocular abnormalities were present 6 months later with continued low-fat diet and insulin administration, although transient recurrence of papules and pruritus occurred after inadvertent access to a fatty meal. An underlying primary hyperlipidaemia was suspected, causing pruritic xanthomas. This may represent the first report of concurrent cutaneous xanthomas, demodicosis and dermatophytosis in a cat.

    Full Text Available Cutaneous leishmanasis (CL may present with unusual clinical variants such as acute paronychial, annular, palmoplantar, zosteriform, erysipeloid, and sporotrichoid. The zosteriform variant has rarely been reported. Unusual lesions may be morphologically attributed to an altered host response or owing to an atypical strain of parasites in these lesions. We report a patient with CL in a multidermatomal pattern on the back and buttock of a man in Khozestan province in the south of Iran. To our knowledge, this is the first reported case of multidermatomal zosteriform CL. It was resistant to conventional treatment but responded well to a combination of meglumine antimoniate, allopurinol, and cryotherapy.

    The adhesive cutaneous pharmaceutical forms aimed to local action release the drug substance in view of a dermatological, traumatological, antirheumatic, cosmetic action. Two such preparations were obtained and their stability, consistency and pH were determined. The "in vitro" tests of their bioavailability revealed the dynamics of calcium ions release according to the associations of each preparation. The bioavailability determined by evaluating the pharmacological response demonstrated the antiinflammatory action obtained by the association of calcium ions with the components extracted from poplar muds. The therapeutical efficiency of the studied preparations has proved in the treatment of some sport injuries.

On the basis of the age of manifestation, acuity of the clinical course and organ involvement Abt-Letterer-Siwe's disease, Hand-Schüller-Christian's disease and eosinophilic granuloma can be differentiated from each other, although transitional varieties of these syndromes are possible. Not infrequently oligosymptomatic forms are misinterpreted, especially when the skin is the only involved organ.

A complete clinical workup could not reveal involvement in any other organ sites and biopsy of one of the cutaneous lesions was diagnosed as histiocytosis X. Because the child was in generally good condition, no treatment was given. Follow-up revealed that the disease had remained limited to the skin, where 15% of the lesions disappeared spontaneously.

    Full Text Available Dissemination of primary cutaneous nocardiosis is a rare event. A 37-year-old man working as farmer presented with multiple painful suppurative nodular and ulcerative skin lesions over left lower extremities, in a linear pattern, with duration of five months and single painful nodule over right elbow since last three months. We found the presence of beaded filamentous bacteria in Gram stain smear and partial acid fast stain, from the smear taken from pus. Patient responded well to cotrimoxazole therapy. Hence, we confirm our diagnosis of sporotrichoid pattern of cutaneous nocardiosis with dissemination to other cutaneous area.

    Full Text Available Cutaneous polyarteritis nodosa (CPAN is a rare form of cutaneous vasculitis that involves small and medium sized arteries of the dermis and subcutaneous tissue without systemic involvement. It presents with tender subcutaneous nodules, digital gangrene, livedo reticularis and subcutaneous ulcerations. The diagnosis is by skin biopsy and characteristic pathologic feature is a leukocytoclastic vasculitis in the small to medium-sized arterioles of the dermis. We report a rare case of benign cutaneous PAN in a 14-year-old girl who presented with history of fever, subcutaneous nodules with cutaneous ulcer and digital gangrene. The skin biopsy showed leukocytoclastic vasculitis with fibrinoid necrosis in the dermal vessels. She received treatment with steroids and lesions resolved completely over a period of month.

    As the skin is commonly involved in systemic vasculitic disorders as well as those hypersensitivity states whose expression is largely skin-confined, cutaneous vasculitic lesions offer a window to diagnosis and a ready source of accessible tissue for biopsy. In this review, we discuss the pathologic manifestations of chronic vasculitic syndromes such as granuloma faciale and erythema elevatum diutinum; IgA-associated vasculitis including Henoch-Schonlein purpura; vasculitis seen in the setting of cryoglobulinemia and hypergammaglobulinemia of Waldenstrom, hereditary deficiencies of complement, and IgA deficiency; those leukocytoclastic vasculitides resulting from hypersensitivity reactions to drug, chemical and foodstuff ingestion; and those vasculitides seen in patients with systemic diseases such as polyarteritis nodosa, rheumatoid arthritis, mixed connective tissue disease, systemic lupus erythematosus, Sjogren's syndrome, relapsing polychondritis, Behcet's disease, Wegener's granulomatosis, and allergic granulomatosis of Churg and Strauss.

    Cutaneous Leishmaniasis (CL) is a vector borne disease caused by various species of the Leishmania parasite. CL is endemic in the province of Balochistan in Pakistan. In certain instances a Human Immunodeficiency Virus (HIV)-related immunocompromised is associated with atypical clinical presentation and occurrence of reactivated lesions of CL. Such presentations respond poorly to the standard treatment and frequent relapses are noted. We are reporting three cases of localized and disseminated CL due to Leishmania tropica which responded to meglumine antimoniate. Due to the fact that CL is endemic in Balochistan, we did not consider HIV infection as a causative organism. It was their presentation with history of weight loss and fever that prompted Enzyme-linked Immunosorbent Assay (ELISA) tests for HIV, which turned out to be positive. CL is becoming visible as an opportunistic infection associated with HIV/AIDS and may even be the first symptom in HIV positive patients in an endemic area.

    Radiotherapy plays an important role in the treatment of cutaneous lymphomas. In the treatment of Mycosis fungoides, total skin electron beam radiation therapy is efficient for patients with limited and superficial forms of the disease. Radiotherapy is also efficient for the locally advanced forms of non-epidermo-tropic lymphomas. The palliative radiotherapy is indicated for advanced, nodular and treatment resistant forms of cutaneous lymphomas and for voluminous lymphadenopathies. (authors)

    Cutaneous angiosarcoma is probably the most malignant neoplasm involving the skin. Three clinical variants of cutaneous angiosarcoma are recognized, including angiosarcoma of the scalp and face of elderly patients, angiosarcoma associated with chronic lymphedema, and postirradiation angiosarcoma. Histopathologically, these three variants of angiosarcoma show similar features, which consist of poorly circumscribed, irregularly dilated, and anastomosing vascular channels lined by prominent endothelial cells that dissect through the dermis. Focally, neoplastic endothelial cells show large, hyperchromatic, and pleomorphic nuclei, protruding within vascular lumina and creating small papillations. Usually, inflammatory infiltrate is sparse and consists of a patchy, perivascular lymphoid infiltrate around the neoformed vessels. In rare instances, cutaneous angiosarcomas may exhibit prominent inflammatory infiltrate, and the neoplasm may be mistaken for an inflammatory process, both from clinical and histopathologic points of view. We describe four examples of cutaneous angiosarcomas with dense lymphocytic infiltrates involving the neoplasm. Immunohistochemically, lymphocytes expressed immunoreactivity for CD3, CD5, and CD45 markers, whereas the germinal centers were positive for CD20, CD79a, and Bcl-6. The neoplastic endothelial cells expressed immunoreactivity for the CD31, CD34, podoplanin, Prox-1, Lyve-1, and D2-40. We discuss the possible relationship between neoplastic endothelial lymphatic cells and reactive lymphocytes. Cutaneous angiosarcoma with prominent lymphocytic infiltrate may be readily mistaken for cutaneous follicle center cell lymphoma or cutaneous pseudolymphoma. PMID:17667166

    Objective: To observe the clinical effects of comprehensive treatmenton cutaneous region for low back pain. Methods: One hundred and twenty outpatients with low back pain who met the diagnostic criteria were randomly divided into a cutaneous region group or a medication group, 60 cases in each group. The cases in the cutaneous region group were treated by Nie-pinching up the skin of the lumbosacral region, cupping and acupuncture. Those in the medication group were treated by oral administration of Celecoxib capsule. The visual analogue scale (VAS) and Oswestry disability index (ODI) were used to assess the therapeutic effects. Results: After treatment, the VAS scores of both groups were different from those before treatment, showing statistical significances (allP Conclusion: Both comprehensive treatment on the cutaneous region and Celecoxib capsule can obviously relieve low back pain. But comprehensive treatment on the cutaneous region is better than Celecoxib capsule in the therapeutic effects.

    Full Text Available Leishmaniasis is a major world health problem, which is increasing in incidence. In Northern Europe it is seen in travellers returning from endemic areas. The protozoa is transmitted by sandflies and may produce a variety of clinical syndromes varying from a simple ulcer to fatal systemic disease. This review considers the management of simple cutaneous leishmaniasis. Patients usually have a single ulcer that may heal spontaneously, requiring only topical, or no treatment at all. Lesions caused by Leishmania braziliensis may evolve into the mucocutaneous form, ′espundia′, and should be treated with systemic antimony. Sodium stibogluconate 20mg/kg/day i.v. for 20 days is the appropriate first line treatment in these cases. Although it may cause transient bone marrow suppression, liver damage, a chemical pancreatitis, and disturbances in the electrocardiogram, it appears safe. The success of treatment should be assessed 6 weeks after it has been completed and patients should be followed up for 6 months.

  8. Aspects of cutaneous ageing.

    1991-09-01

    'Ageing is a multistep, multifaceted, time-dependent phenomenon characterized by the decreased ability of a system to respond to exogenous and endogenous stress from either physical, chemical or biologic agents'. Cutaneous ageing provides a visible model of the interaction between endogenous (intrinsic) factors and exogenous (extrinsic) factors. In skin, the principal extrinsic-factor is ultraviolet light (UV) which is responsible for the constellation of changes termed photoageing. In recent years, much interest has been directed towards defining the ageing processes in skin and excellent comprehensive reviews have been compiled. This review aims to highlight several areas of developing knowledge, and focuses on the potential importance of environmental changes as they influence skin ageing and carcinogenesis. Repeated reference to the effects of UV on the skin are inevitable in any review of skin ageing and this is scarcely surprising as the skin contains many cells as well as subcellular and extracellular chromophores which are capable of absorbing energy within the UV spectrum. Cellular chromophores include among others keratinocytes, melanocytes, Langerhans cells, dermal fibroblasts and mast cells. Subcellular chromophores include keratin, melanin, collagen, elastin and a number of proteins, lipids and steroids (such as vitamin D). Urocanic acid, a photoisomerization product of the amino-acid histidine, may provide some limited photoprotection and some believe it to be important in UV induced immunosuppression. Understanding events at the molecular and biochemical level has unfortunately not been paralleled by clinical advances and the common, troublesome skin-problems of old age such as cancer, xerosis and pruritus remain a major cause of morbidity and yet are poorly explained.

    Full Text Available Importance. Cutaneous and systemic plasmacytosis are rare conditions of unknown etiology with characteristic red-brown skin lesions and a mature polyclonal plasma cell infiltrate within the dermis. Perineural plasma cell infiltrates may be a histologic clue to the diagnosis of cutaneous plasmacytosis. Observations. Our patient had a five-year history of persistent reddish-brown plaques on the neck and trunk without systemic symptoms. Histologic examination showed dermal perivascular and perineural plasma cells with excess lambda light chain expression. Due to decreased quality of life caused by his skin lesions, he was placed on a chemotherapeutic regimen with bortezomib. Conclusions and Relevance. The patient was diagnosed with cutaneous plasmacytosis based on classic histopathology results with a recently characterized pattern of perineural involvement. Bortezomib therapy was initiated to manage his skin eruption, which has not been previously described as a treatment for this chronic condition.

    Full Text Available Microemulsions are fluid and isotropic formulations that have been widely studied as delivery systems for a variety of routes, including the skin. In spite of what the name suggests, microemulsions are nanocarriers, and their use as topical delivery systems derives from their multiple advantages compared to other dermatological formulations, such as ease of preparation, thermodynamic stability and penetration-enhancing properties. Composition, charge and internal structure have been reported as determinant factors for the modulation of drug release and cutaneous and transdermal transport. This manuscript aims at reviewing how these and other characteristics affect delivery and make microemulsions appealing for topical and transdermal administration, as well as how they can be modulated during the formulation design to improve the potential and efficacy of the final system.

    1996-12-01

    Ultraviolet radiation (UVR) present in sunlight is a major environmental factor capable of affecting human health and well being. The organ primarily affected by UVR is the skin, which is composed of a variety of different cell types. Here, UVR is needed for production of active vitamin D as well as producing undesirable effects such as sunburn, premature cutaneous photoaging, and promoting skin cancer development. Depending on the radiation dose, UVR influences virtually every cutaneous cell type investigated differently. Since the end of the nineteenth century, sun exposure has been known to induce skin cancer, which is now the human malignancy with the most rapidly increasing incidence. In several experimental models, mid-range UVR has been demonstrated to be the major cause of UV-induced cutaneous tumors. The stratospheric ozone layer protecting the terrestrial surface from higher quantum energy solar radiation is being damaged by industrial activities resulting in the possibility of increased UVR exposure in the future. Investigations in the field of experimental dermatology have shown that within the skin an immunosurveillance system exists that may be able to detect incipient neoplasms and to elicit a host responses against it. This article reviews the literature on studies designed to investigate the effects of UVR on cutaneous cellular components, with special focus on the immune system within the skin and the development of UV-induced cancer.

    The aim of this study is to present 2 rare cases of cutaneous metastases originated from adenocarcinoma of the gastro-esophageal junction, thus, underline the need for early diagnosis and possible treatment of suspicious skin lesions among patients with esophageal malignancy. Metastatic cancer to the skin originated from internal malignancies, mostly lung cancer, breast cancer, and colorectal cancer, constitute 0.5 to 9% of all metastatic cancers.5,8,15 Skin metastases, mainly from squamous cell carcinomas of the esophagus, are rarely reported. Cutaneous metastasis is a finding indicating progressiveness of the disease.17 More precisely, median survival is estimated approximately 4.7 months.2,14 This study is a retrospective review of 2 cases of patients with adenocarcinoma of the esophagus and a review of the literature. Two patients aged 60 and 32 years old, respectively, underwent esophagectomy. Both pathologic reports disclosed adenocarcinoma of the gastro-esophageal junction staged T3 N2 M0 (stage IIIB). During follow-up time, the 2 patients were diagnosed with cutaneous metastases originated from the primary esophageal tumor 11 and 4 months after surgery, respectively. The first patient is alive 37 months after diagnosis, while the second one died 16 months after surgery. Cutaneous metastasis caused by esophageal adenocarcinoma is possible. Therefore, follow-up of patients who were diagnosed with esophageal malignancy and underwent esophagectomy is mandatory in order to reveal early surgical stages. PMID:25785344

    Chemicals have become indispensible for the maintenance of health in animals and man. The route of administration of each medicament is decided by factors such as site of desired action, chemistry of the active ingredient, age and species of the patient, and frequency of administration (or desired duration of activity). In situations where the oral and hypodermic routes, which are used most frequently, are inadequate or unsatisfactory, dermal application can provide a valuable alternative method to achieve systemic activity. Examples of formulations currently available for dermal application contain diverse chemicals and are intended for a variety of purposes, such as crufomate against cattle grubs, fenthion against cattle lice, levamisole against gastrointestinal nematodes, nitroglycerine for angina pectoris, and scopolamine for motion sickness. The skin acts as a barrier to penetration by chemicals and micro-organisms by virtue of its morphology and chemical composition. Chemicals which do penetrate, do not necessarily pass through the appendages (hair follicles and gland ducts), but mostly penetrate through the interjacent epidermis, either through the cells, or via the intracellular spaces. These spaces have recently been shown by electron microscopy to be filled by an amorphous substance which exudes on the skin surface in convex ridges. This substance has a lipid nature, but is not hydrophobic as is often accepted. For a chemical to be able to penetrate the skin, it must be partially water and lipid soluble, polar, and weakly ionizing. A variety of factors can possibly affect the permeability of skin for a chemical. These include species differences in morphology (skin thickness, tightness of intercellular junctions, density of hair follicles and other appendages), biochemistry, and physiology; seasonal and climatic variations; and differences between breeds and genders. Species differences in skin permeability are largely unpredictable and inconsistent. An

    In Mexico, 6 cases of diffuse cutaneous leishmaniasis (DCL) were found in widely separated geographic regions. Information was also available on 2 other cases. In addition to the typical clinical features, half of the patients had evidence of nasopharyngeal mucosal involvement. All isolates from the DCL patients were identified as Leishmania mexicana mexicana by isoenzyme analysis and monoclonal antibody typing. In 1 region of Tabasco state where DCL was found, uncomplicated cutaneous leishmaniasis appeared to be highly endemic, and isolates from a few such patients were identified as L. mexicana mexicana. An incidental finding was the recovery of an isolate of L. braziliensis braziliensis from a patient with chiclero ulcer in Oaxaca state.

    The underlying molecular basis of primary cutaneous lymphomas has not yet been clarified. However, abnormalities of cell cycle control genes and well-defined tumor suppressor genes such as p53 are common and may contribute to disease progression and treatment resistance. Biallelic inactivation of tumor suppressor genes usually occurs by a combination of deletion, point mutation, and/or promotor hypermethylation. The detection of UVB-specific mutations of p53 requires confirmation but may have important implications for the management of patients with mycosis fungoides. Molecular cytogenetic studies have identified common regions of chromosomal deletion and amplification, which suggests the presence and location of genes that are of critical importance in the pathogenesis of cutaneous lymphoma.

    Full Text Available Plexiform schwannoma is a rare neurogenic tumor, arising from skin and subcutaneous tissue. The presence of multiple schwannomas suggests a possible association with neurofibromatosis type 2 (NF2. A 50-year old male patient presented with multiple papulo-nodular cutaneous lesions on both arms and forearms. Histopathological examination revealed a dermal multinodular pattern of well-circumscribed masses of closely packed cells, with peripheral myxoid tissue, well-encapsulated in a thin collagenous capsule. S-100 immunohistochemical staining was diffusely and strongly positive. Neuron-specific enolase was positive, confirming a neural tissue tumor. An audiogram and Magnetic Resonance Imaging (MRI of cerebro-pontine angle showed no detected abnormality, excluding acoustic neuroma. Thus, we present a case of multiple bilateral isolated cutaneous plexiform schwannomas, not associated with NF2. Multiple plexiform schwannomas is a very rare entity, distinct from neurofibromatosis (NF, and being confined to the dermis is even more rarely reported.

    Angiosarcoma is a rare and highly malignant tumor with potential to recur despite treatment, and carries a poor prognosis. Previous radiation therapy and lymphedema are some of the known risk factors. We present a case of cutaneous angiosarcoma which occurred at lumpectomy site in a patient with a history of breast cancer and radiation to the breast. The tumor kept on recurring repetitively despite continual treatments, and the patient finally succumbed to the disease roughly four years after initial diagnosis. PMID:18925942

    2012-01-01

    We report a case of a 22-year-old previously healthy woman with Hodgkin's lymphoma who presented initially with multiple lymphadenopathy and later, with a solitary cutaneous ulcer. Unlike Non-Hodgkin's lymphoma subtypes, skin involvement of Hodgkin's lymphoma is extremely rare. The prognosis of Hodgkin's lymphoma with skin infiltration is felt to be extremely poor. Contrary to other reports, this case demonstrates that a good response with standard therapy is possible.

    Parasitic diseases result in a significant global health burden. While often thought to be isolated to returning travelers, parasitic diseases can also be acquired locally in the United States. Therefore, clinicians must be aware of the cutaneous manifestations of parasitic diseases to allow for prompt recognition, effective management, and subsequent mitigation of complications. This commentary also reviews pharmacologic treatment options for several common diseases. PMID:27621348

    The TNFalpha antagonists, including adalimumab, etanercept and infliximab, represent a class of anti-inflammatory and immunosuppressive drugs. Although cutaneous adverse effects are uncommon, they are varied. There is no particular risk profile to develop cutaneous adverse effects. The principal acute side effects are injection site reactions and pruritus. The major long term cutaneous side effects are infectious and inflammatory conditions. Neoplastic skin diseases are exceptional. The association with other immunosuppressive agents can increase the risk of developing cutaneous adverse effects. Some adverse effects, such as lupus erythematosus, require immediate withdrawal of the biological treatment, while in other cases temporary withdrawal is sufficient. The majority of the other cutaneous adverse effects can be dealt without interrupting biologic treatment. Preclinical and clinical investigations revealed that the new biologics, aiming IL12/23, IL23 and IL17, present a similar profile of cutaneous adverse effects, although inflammatory skin reactions may be less often encountered compared to TNFalpha antagonists.

    Cutaneous larva migrans or creeping eruptions is a cutaneous dermatosis caused by hookworm larvae, Ancylostoma braziliense. A 2-month-old female child presented with a progressive rash over the left buttock of 4 days duration. Cutaneous examination showed an urticarial papule progressing to erythematous, tortuous, thread-like tract extending a few centimeters from papule over the left gluteal region. A clinical diagnosis of cutaneous larva migrans was considered. Treatment with albendazole led to complete resolution, confirming the diagnosis. This is to the best of our knowledge, the youngest age at which this condition is being reported. PMID:26538729

    Full Text Available Background: Cutaneous hyperpigmentation is an often overlooked clinical sign in megaloblastic anemia (MA which has been sporadically reported in the literature. Methods: We describe the bone marrow (BM changes and clinicolaboaratory characteristics of 25 of 198 adult cases (>16 years with cutaneous hyperpigmentation who underwent BM evaluation for cytopenia (s. Results:  Twenty-one of 25 cases (84% had MA, while MA without hyperpigmentation occurred only in 12 of remainder 173 cases (P0.05. In six cases where follow-up data were available, there was significant reversal of hyperpigmentation at 12 weeks following parenteral cobalamine therapy. In all five cases with pyrexia, fever subsided after 24 to 72 hours following administration of parenteral cobalamine therapy. Conclusion: Cutaneous hyperpigmentation, pyrexia, and cytopenia (s are strongly associated with megaloblastic anemia. Knuckle pad hyperpigmentation is much more common than diffuse pigmentation of the palms and/or soles in such patents. A nonsignificant trend towards a greater degree of MA was found in cases with pigmentation of the knuckles.

    Full Text Available Background: Cutaneous leishmaniasis (CL is known for its clinical diversity and increasing numbers of new and rare variants of the disease are being reported these days. Aim: The aim of this descriptive study was to look for and report the atypical presentations of this common disease occurring in Pakistan. Methods: The study was carried out in three hospitals (MH, Rawalpindi; PAF Hospital, Sargodha; and CMH, Muzaffarabad from 2002 to 2006. Military and civilian patients of all ages, both males and females, belonging to central and north Punjab province and Kashmir were included in the study. Clinical as well as parasitological features of cutaneous leishmaniasis were studied. The unusual lesions were photographed and categorized accordingly using simple descriptive statistics. Results: Out of 718 patients of cutaneous leishmaniasis, 41 (5.7% had unusual presentations. The commonest among unusual morphologies was lupoid leishmaniasis 14 (34.1%, followed by sporotrichoid 5 (12.1%, paronychial 3 (7.3%, lid leishmaniasis 2 (4.9%, psoriasiform 2 (4.9%, mycetoma-like 2 (4.9%, erysipeloid 2 (4.9%, chancriform 2 (4.9%, whitlow 1 (2.4%, scar leishmaniasis 1 (2.4%, DLE-like 1 (2.4%, ′squamous cell carcinoma′-like 1 (2.4%, zosteriform 1 (2.4%, eczematous 1 (2.4%, verrucous 1 (2.4%, palmar/plantar 1 (2.4% and mucocutaneous 1 (2.4%.

    Full Text Available Carcinoma of the uterine cervix is the most common gynecological malignancy in developing countries. However, its cutaneous metastasis is a rare entity. The reported incidence of cutaneous metastasis ranges from 0.1 to 2%. Frequent sites of cutaneous metastasis in decreasing order are: abdominal wall, vulva and anterior chest wall. To the best of our knowledge, only three cases of cutaneous metastasis to the upper extremity have been reported in the world. We report a case of a 74-year-old postmenopausal lady diagnosed to have carcinoma cervix (stage IIIB who presented with cutaneous metastasis to palm and thigh, 10 months after radical radiotherapy. At presentation, the primary disease had resolved completely. She had a small nodular growth in the left palm and left thigh. Fine needle aspirate cytology and core needle biopsy from both the nodular lesions were positive for squamous cell carcinoma.

    The known spectrum of skin manifestations in cutaneous Lyme disease is continuously expanding and can not be regarded as completed. Besides the classical manifestations of cutaneous borreliosis like erythema (chronicum) migrans, borrelial lymphocytoma and acrodermatitis chronica atrophicans evidence is growing that at least in part also other skin manifestations, especially morphea, lichen sclerosus and cases of cutaneous B-cell lymphoma are causally related to infections with Borrelia. Also granuloma annulare and interstitial granulomatous dermatitis might be partly caused by Borrelia burgdorferi or similar strains. There are also single reports of other skin manifestations to be associated with borrelial infections like cutaneous sarcoidosis, necrobiosis lipoidica and necrobiotic xanthogranuloma. In addition, as the modern chameleon of dermatology, cutaneous borreliosis, especially borrelial lymphocytoma, mimics other skin conditions, as has been shown for erythema annulare centrifugum or lymphocytic infiltration (Jessner Kanof) of the skin.

    Abstract Aim: To provide an overview of the medical literature on cutaneous fistulization in patients with hydatid disease (HD). Methods: According to PRISMA guidelines a literature search was made in PubMed, Medline, Google Scholar, and Google databases were searched using keywords to identify articles related to cutaneous fistulization of the HD. Keywords used were hydatid disease, hydatid cyst, cutaneous fistulization, cysto-cutaneous fistulization, external rupture, and external fistulization. The literature search included case reports, review articles, original articles, and meeting presentations published until July 2016 without restrictions on language, journal, or country. Articles and abstracts containing adequate information, such as age, sex, cyst size, cyst location, clinical presentation, fistula opening location, and management, were included in the study, whereas articles with insufficient clinical and demographic data were excluded. We also present a new case of cysto-cutaneous fistulization of a liver hydatid cyst. Results: The literature review included 38 articles (32 full text, 2 abstracts, and 4 unavailable) on cutaneous fistulization in patients with HD. Among the 38 articles included in the study, 22 were written in English, 13 in French, 1 in German, 1 in Italian, and 1 in Spanish. Forty patients (21 males and 19 females; mean age ± standard deviation, 54.0 ± 21.5 years; range, 7–93 years) were involved in the study. Twenty-four patients had cysto-cutaneous fistulization (Echinococcus granulosus); 10 had cutaneous fistulization (E multilocularis), 3 had cysto-cutaneo-bronchio-biliary fistulization, 2 had cysto-cutaneo-bronchial fistulization; and 1 had cutaneo-bronchial fistulization (E multilocularis). Twenty-nine patients were diagnosed with E granulosis and 11 had E multilocularis detected by clinical, radiological, and/or histopathological examinations. Conclusion: Cutaneous fistulization is a rare complication of HD

    Full Text Available Three unusual clinical forms of sporotrichosis described in this paper will be a primer for the clinicians for an early diagnosis and treatment, especially in its unusual presentations. Case 1, a 52-year-old man, developed sporotrichosis over pre-existing facial nodulo-ulcerative basal cell carcinoma of seven-year duration, due to its contamination perhaps from topical herbal pastes and lymphocutaneous sporotrichosis over right hand/forearm from facial lesion/herbal paste. Case 2, a 25-year-old woman, presented with disseminated systemic-cutaneous, osteoarticular and possibly pleural (effusion sporotrichosis. There was no laboratory evidence of tuberculosis and treatment with anti-tuberculosis drugs (ATT did not benefit. Both these cases were diagnosed by histopathology/culture of S. schenckii from tissue specimens. Case 3, a 20-year-old girl, had multiple intensely pruritic, nodular lesions over/around left knee of two-year duration. She was diagnosed clinically as a case of prurigo nodularis and histologically as cutaneous tuberculosis, albeit, other laboratory investigations and treatment with ATT did not support the diagnosis. All the three patients responded well to saturated solution of potassium iodide (SSKI therapy. A high clinical suspicion is important in early diagnosis and treatment to prevent chronicity and morbidity in these patients. SSKI is fairly safe and effective when itraconazole is not affordable/ available.

    2015-04-01

    Cutaneous vasculitides (CV) can be idiopathic or secondary to several triggers, including drugs, which account for up to 30% of all the cases of CV. Several drugs can induce CV, including some medications commonly used in dermatology, including minocycline, and several new drugs, such as anti-TNF agents. Different pathomecanisms are involved in the development of drug-induced CV, including the formation and deposition of immune complexes, the induction of neutrophil apoptosis, the formation of neoantigens between the drugs and proteins from the host, the shift of the immune response, and others. Although the diagnosis is difficult, because the clinical picture of drug-induced CV is in general indistinguishable from that of other forms of CV, it is important to recognize such entities in order to correctly manage the patient. Anamnesis, diagnostic algorithms to assess the likelihood of the association between a drug and a cutaneous reaction, skin biopsy and laboratory testing (including the search for antineutrophil cytoplasmic antibodies) are useful tools to make a diagnosis of drug-induced CV. About the therapy, while in idiopathic vasculitides the treatment is usually more aggressive and long-lasting, very often requiring a maintenance therapy with immunosuppressive drugs, in drug-induced CV the discontinuation of the suspected drug alone is usually enough to achieve complete remission, making the prognosis usually very good.

  14. Selenium for the Prevention of Cutaneous Melanoma

    Directory of Open Access Journals (Sweden)

    Douglas Grossman

    2013-03-01

    Full Text Available The role of selenium (Se supplementation in cancer prevention is controversial; effects often depend on the nutritional status of the subject and on the chemical form in which Se is provided. We used a combination of in vitro and in vivo models to study two unique therapeutic windows for intervention in the process of cutaneous melanomagenisis, and to examine the utility of two different chemical forms of Se for prevention and treatment of melanoma. We studied the effects of Se in vitro on UV-induced oxidative stress in melanocytes, and on apoptosis and cell cycle progression in melanoma cells. In vivo, we used the HGF transgenic mouse model of UV-induced melanoma to demonstrate that topical treatment with l-selenomethionine results in a significant delay in the time required for UV-induced melanoma development, but also increases the rate of growth of those tumors once they appear. In a second mouse model, we found that oral administration of high dose methylseleninic acid significantly decreases the size of human melanoma xenografts. Our findings suggest that modestly elevation of selenium levels in the skin might risk acceleration of growth of incipient tumors. Additionally, certain Se compounds administered at very high doses could have utility for the treatment of fully-malignant tumors or prevention of recurrence.

    A 17-year-old spayed female domestic shorthair cat was referred for evaluation of severe skin lesions, including ulceration, nodule formation, erythema, and alopecia. Cutaneous nonepitheliotropic lymphoma was diagnosed histologically. There was no evidence of visceral organ involvement, but renal function was decreased. The cat was treated with lomustine (45.5 mg/m2, PO, q 21 d), and skin lesions resolved after administration of the third dose. No severe toxicoses were identified. Results suggest that lomustine may be useful for treatment of cutaneous nonepitheliotropic lymphoma in cats; however, optimal dosage, efficacy, and potential adverse effects must be determined.

    Primary cutaneous lymphomas are currently classified by the European Organization for Research and Treatment of Cancer (EORTC) classification or the World Health Organization (WHO) classification, but both systems have shortcomings. In particular, differences in the classification of cutaneous T-cell lymphomas other than mycosis fungoides, Sezary syndrome, and the group of primary cutaneous CD30+ lymphoproliferative disorders and the classification and terminology of different types of cutaneous B-cell lymphomas have resulted in considerable debate and confusion. During recent consensus meetings representatives of both systems reached agreement on a new classification, which is now called the WHO-EORTC classification. In this paper we describe the characteristic features of the different primary cutaneous lymphomas and other hematologic neoplasms frequently presenting in the skin, and discuss differences with the previous classification schemes. In addition, the relative frequency and survival data of 1905 patients with primary cutaneous lymphomas derived from Dutch and Austrian registries for primary cutaneous lymphomas are presented to illustrate the clinical significance of this new classification.

    A detailed anatomic study was carried out on the lateral femoral cutaneous nerve to better understand the etiology and treatment of lateral femoral cutaneous neuralgia. As it passed from the pelvis into the thigh, the lateral femoral cutaneous nerve ran through an "aponeuroticofascial tunnel," beginning at the iliopubic tract and ending at the inguinal ligament; as it passed through the tunnel, an enlargement in its side-to-side diameter was observed, suggesting that the fascial structures proximal to the inguinal ligament may be implicated in the genesis of lateral femoral cutaneous neuralgia. The finding of pseudoneuromas at this location, distant from the inguinal ligament, supports this hypothesis. The anterior superior iliac spine is located approximately 0.7 cm from the lateral femoral cutaneous nerve and serves as the bony landmark for nerve localization. Within the first 3 cm of leaving the pelvis, the lateral femoral cutaneous nerve was observed deep to the fascia lata; therefore, surgical dissection within the subcutaneous fascia may be conducted with relative impunity near the anterior superior iliac spine just inferior to the inguinal ligament. In 36% of cases there was no posterior branch of the nerve, which is correlated to lateral femoral cutaneous neuralgia symptoms often being limited to the anterior branch region. An accessory nerve was found in 30% of cases. PMID:12794914

    Full Text Available Malaria is an infectious disease caused by protozoa of the genus Plasmodium. Cutaneous lesions in malaria are rarely reported and include urticaria, angioedema, petechiae, purpura, and disseminated intravascular coagulation (DIC. Here, five malaria cases associated with cutaneous lesions have been described. Out of the five cases of malaria, two were associated with urticaria and angioedema, one case was associated with urticaria, and other two were associated with reticulated blotchy erythema with petechiae. Most of the cutaneous lesions in malaria were nonspecific and reflected the different immunopathological mechanism in malarial infection.

    Alternariosis is a fungal infection that is usually described in immunocompromised patients. We report a case of cutaneous alternariosis in a renal transplant recipient caused by Alternaria tenuissima. The diagnosis was supported by histopathologic (ie, yeastlike cells, filamentous structures) and mycologic findings from a cutaneous biopsy. Cutaneous lesions regressed 1 month following a decrease in the dosage of immunosuppressive therapy. The patient also was treated with intravenous amphotericin B followed by oral fluconazole without improvement. Cryotherapy remarkably accelerated healing of the lesions. PMID:24897135

  1. Cutaneous Manifestations in Inflammatory Bowel Diseases

    Simona Roxana Georgescu

    2015-10-01

    Full Text Available Inflammatory bowel diseases have a high frequency in Europe. They are chronic disorders that evolve with relapses and remissions. Clinical features include the signs of underlying inflammatory bowel disease and also signs of extraintestinal manifestations. Cutaneous disorders are the most common extraintestinal manifestations associated with inflammatory bowel diseases, which can be dependent on or independent of gastrointestinal disease activity. The main cutaneous disorders are erythema nodosum and pyodermagangrenosum. The pathogenic mechanisms are not fully understood but it seems that related mechanisms are involved in the development of inflammatory bowel diseases and extraintestinal manifestations. Treatment should be aimed at both the cutaneous manifestations and the bowel inflammation

    Full Text Available We report two occupationally acquired cases of American cutaneous leishmaniasis (ACL: one accidental laboratory autoinoculation by contaminated needlestick while handling an ACL lesion sample, and one acquired during field studies on bird biology. Polymerase chain reaction (PCR assays of patient lesions were positive for Leishmania, subgenus Viannia. One isolate was obtained by culture (from patient 2 biopsy samples and characterized as Leishmania (Viannia naiffi through an indirect immunofluorescence assay (IFA with species-specific monoclonal antibodies (mAbs and by multilocus enzyme electrophoresis (MLEE. Patients were successfully treated with N-methyl-glucamine. These two cases highlight the potential risks of laboratory and field work and the need to comply with strict biosafety procedures in daily routines. The swab collection method, coupled with PCR detection, has greatly improved ACL laboratory diagnosis.

    Niacin, also known as vitamin B3, is required for the synthesis of coenzymes, nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Niacin binds with G protein-coupled receptor (GPR) 109A on cutaneous Langerhans cells and causes vasodilation with flushing in head and neck area. Niacin deficiency due to excessive alcohol consumption, certain drugs or inadequate uptake in diet causes pellagra, a photosensitivity dermatitis. Recently several studies have revealed the mechanism of photosensitivity in niacin deficiency, which may pave a way for new therapeutic approaches. The expression level of prostaglandin E synthase (PTGES) is up-regulated in the skin of both pellagra patients and niacin deficient pellagra mouse models. In addition, pellagra is mediated through prostaglandin E₂-EP4 (PGE₂-EP4) signaling via reactive oxygen species (ROS) production in keratinocytes. In this article, we have reviewed the role of niacin in immunity and the mechanism of niacin deficiency-induced photosensitivity. PMID:25765687

    Full Text Available Cutaneous leishmaniasis (CL is a widespread tropical infection caused by numerous different species of Leishmania protozoa. In our country, CL is due frequently to L. major and L. tropica. Its clinical presentation is extremely diverse. Treatment of CL aims to prevent mucosal invasion, to accelerate the healing of skin lesions, and avoid disfiguring scar. Local and physical treatment modalities including topical paromomycin, cryotherapy, localized controlled heat, carbon dioxide laser therapy, or pentavalant antimonals can be effective against. Intralesional antimonals are still the drug of choice may patients. WHO recommends an injection of drug under edges of the lesions and the entire lesion until the surface has blanched. Parenteral antimonials are useful for large, persistent or recurrent lesions. Combinations with other drugs such as allopurinol, pentoxifylline must be used for antimony unresponsive lesions.

    Arfa, Kenneth S.

    2016-01-01

    Background: Ferrofluid is a colloidal suspension that usually consists of surfactant-coated nanoparticles of magnetite (Fe3O4) in a carrier liquid. Ferromagnetic fluid forms spikes when the liquid is exposed to a magnetic field. Purpose: The authors describe a man who developed temporary discoloration of his right palm and fingers after accidental cutaneous contact with ferrofluid and discuss some of the current and potential applications of this unique liquid. Methods: A 28-year-old man was evaluating the effects of magnetic fields using ferrofluid. He performed a modification of the “leaping ferrofluid” demonstration in which he held a superstrong (14,800 gauss magnetic field strength) N52 rare earth neodymium magnet in his palm and slowly lowered that hand over an open bowl that was filled with ferrofluid. Results: As the magnet approached the liquid, the ferrofluid became magnetized. The liquid leaped from the bowl and contacted not only the magnet, but also the palmar surface of his hand and fingers, resulting in a black-brown dyschromia of the affected skin. The discoloration completely resolved after two weeks without any adverse sequellae. Conclusion: Ferrofluid has numerous current and potential applications; in addition to being of value educationally and aesthetically (after being subjected to magnetic fields), it is also utilized for audio loudspeakers, medical innovations (such as a component of either a research tool, a diagnostic aid, or a treatment modality), and seals. Although the authors’ patient did not experience any acute or chronic toxicity from his cutaneous exposure to ferrofluid, conservative follow-up for individuals who experience skin contact with ferromagnetic fluid may be appropriate.

    A two-year-old, neutered female cross-bred labrador had multiple cutaneous nodules, biopsies of which revealed pathological changes consistent with cutaneous histiocytosis. During a period of one month the dog developed multicentric lymphadenopathy, a retrobulbar mass and masses within the quadriceps and cervical muscles. Fine needle aspiration cytology of the cutaneous nodules and lymph nodes and histological examination of the cutaneous nodules and muscle masses suggested the presence of lymphoblastic lymphoma. A definitive diagnosis of CD8+ T cell lymphoma was achieved by immunophenotyping the tumour cells by flow cytometry.

    The United States continues to be a prime target for attack by terrorist organizations in which nuclear detonation and dispersal of radiological material are legitimate threats. Such attacks could have devastating consequences to large populations, in the form of radiation injury to various human organ systems. One of these at risk organs is the cutaneous system, which forms both a physical and immunological barrier to the surrounding environment and is particularly sensitive to ionizing radiation. Therefore, increased efforts to develop medical countermeasures for treatment of the deleterious effects of cutaneous radiation exposure are essential. Interleukin-12 (IL-12) was shown to elicit protective effects against radiation injury on radiosensitive systems such as the bone marrow and gastrointestinal tract. In this article, we examined if IL-12 could protect the cutaneous system from a combined radiation injury in the form of sublethal total body irradiation and beta-radiation burn (β-burn) directly to the skin. Combined radiation injury resulted in a breakdown in skin integrity as measured by transepidermal water loss, size of β-burn lesion and an exacerbated loss of surveillant cutaneous dendritic cells. Interestingly, intradermal administration of IL-12 48 h postirradiation reduced transepidermal water loss and burn size, as well as retention of cutaneous dendritic cells. Our data identify IL-12 as a potential mitigator of radiation-induced skin injury and argue for the further development of this cytokine as a radiation countermeasure. PMID:25564716

    Full Text Available Bacillus anthracis is the causative agent of anthrax. Anthrax is a zoonotic disease with three clinical forms. Clinical forms are skin, gastrointestinal and inhalational anthrax. Cutaneous anthrax is 95% of the cases. Cutaneous anthrax frequently defines itself. Clinical presentation of anthrax may be severe and complicated in some cases. There may seem complications like meningitis, septic shock and compartment syndrome. Compartment Syndrome is a rare complication of cutaneous anthrax and it is life threatening. Physicians working in the endemic area should be aware of this form. In this study, three cases were shown which developed compartment syndrome following cutaneous anthrax. J Microbiol Infect Dis 2013;3(4: 214-217

    Nutritional deficiencies may be associated with a variety of cutaneous findings in children. This review emphasizes new developments relating to cutaneous findings of nutritional deficiencies. Zinc deficiency, acrodermatitis enteropathica, and acrodermatitis enteropathica-like eruptions are seen with a variety of conditions including cystic fibrosis, anorexia nervosa, and breastfeeding. Similar cutaneous findings not related to zinc deficiency may also occur with such metabolic disorders as methylmalonic aciduria, multiple carboxylase deficiency, essential fatty acid deficiency and other amino acid deficiencies. Vitamin K deficiency is associated with hemorrhagic disease of the newborn and coagulopathy. Vitamin A deficiency presents with a variety of systemic findings and distinctive dermatologic findings. Acute vitamin A deficiency may be seen in children infected with measles and is associated with more severe disease. The systemic and cutaneous findings of vitamin C deficiency, scurvy, are discussed. PMID:8374671

    Cutaneous metastases may cause considerable discomfort as a consequence of ulceration, oozing, bleeding and pain. Electrochemotherapy has proven to be highly effective in the treatment of cutaneous metastases. Electrochemotherapy utilises pulses of electricity to increase the permeability of the ...... cell membrane and thereby augment the effect of chemotherapy. For the drug bleomycin, the effect is enhanced several hundred-fold, enabling once-only treatment. The primary endpoint of this study is to evaluate the efficacy of electrochemotherapy as a palliative treatment....

    Cutaneous manifestations of lupus erythematosus (LE) are, usually, characteristic enough to permit an easy diagnosis. However, some patients may present less typical lesions, associated or not to the classic ones. Therefore, irrespectively of the variety of LE (acute, subacute and chronic), in absence of the typical butterfly rash, erythematosquamous papules or plaques, or any of the characteristic cutaneous alterations, it is important (even though not always easy) to recognize the uncommon and/or atypical changes of the skin.

    2013-07-01

    The sense of force is critical in the control of movement and posture. Multiple factors influence our perception of exerted force, including inputs from cutaneous afferents, muscle afferents and central commands. Here, we studied the influence of cutaneous feedback on the control of ankle force output. We used repetitive electrical stimulation of the superficial peroneal (foot dorsum) and medial plantar nerves (foot sole) to disrupt cutaneous afferent input in 8 healthy subjects. We measured the effects of repetitive nerve stimulation on (1) tactile thresholds, (2) performance in an ankle force-matching and (3) an ankle position-matching task. Additional force-matching experiments were done to compare the effects of transient versus continuous stimulation in 6 subjects and to determine the effects of foot anesthesia using lidocaine in another 6 subjects. The results showed that stimulation decreased cutaneous sensory function as evidenced by increased touch threshold. Absolute dorsiflexion force error increased without visual feedback during peroneal nerve stimulation. This was not a general effect of stimulation because force error did not increase during plantar nerve stimulation. The effects of transient stimulation on force error were greater when compared to continuous stimulation and lidocaine injection. Position-matching performance was unaffected by peroneal nerve or plantar nerve stimulation. Our results show that cutaneous feedback plays a role in the control of force output at the ankle joint. Understanding how the nervous system normally uses cutaneous feedback in motor control will help us identify which functional aspects are impaired in aging and neurological diseases.

    A 92-year-old man presented with months of progressive blurry vision, worsening acutely in his right eye. He denied pain, diplopia, or photopsias. His history was significant for multiple myeloma, prostate cancer, and malignant melanoma of his right shoulder treated with local excision. He had local recurrence with hepatic metastasis of the melanoma treated with radiation and chemotherapy. On examination, his visual acuity was counting fingers in the right eye and 20/60 in the left eye. Amsler grid testing demonstrated metamorphopsia in the right eye. Fundus exam of the right and left eyes revealed multiple, elevated, pigmented choroidal lesions, with associated subretinal fluid in the right macula. This appearance is consistent with hematogenous metastasis of cutaneous malignant melanoma to the choroid and associated serous fluid-causing metamorphopsia. The patient was enrolled in a clinical trial combining plasmid IL-12 with pembrolizumab (Keytruda; Merck, Whitehouse Station, NJ). He passed away 2 months after initial presentation to our clinic.

    Vasculitis is characterized by an inflammatory reaction of vessel walls with damage to the dependent tissues. Forms of vasculitis which frequently have skin changes include leukocytoclastic angiitis (LcV), Henoch-Schönlein purpura (HSP), cutaneous polyarteriitis nodosum (cPAN), erythema elevatum et diutinum (EED) and urticarial vasculitis (UV). In other forms of vasculitis, systemic manifestations predominate but there are a variety of skin changes. Kawasaki disease (MK), cryoglobulinemic vasculitis (kV), Wegener granulomatosis (WG), Churg-Strauss syndrome (CSS) and microscopic polyangitis (MPA) belong to this group. The causes of vasculitis are heterogeneous. Triggers include infections, drugs, collagen vascular diseases, autoimmune diseases and lymphoproliferative disorders. Idiopathic vasculitis, particularly LcV and EED, occur only once and have a self-limited course. The diagnostic work up depends on the clinical picture and includes inflammatory markers, circulating immune complexes, different types of cryoglobulins and anti-neutrophilic cytoplasmic antibodies, collagen vascular disease specific autoantibodies and additional hematological studies. Vasculitis can manifest in many organs and requires a thorough work up specifically in cases where WG, MPA, CSS and PAN are under consideration. PMID:18415062

  1. Cutaneous interstitial nitric oxide concentration does not increase during heat stress in humans

    2001-01-01

    Inhibition of cutaneous nitric oxide (NO) synthase reduces the magnitude of cutaneous vasodilation during whole body heating in humans. However, this observation is insufficient to conclude that NO concentration increases in the skin during a heat stress. This study was designed to test the hypothesis that whole body heating increases cutaneous interstitial NO concentration. This was accomplished by placing 2 microdialysis membranes in the forearm dermal space of 12 subjects. Both membranes were perfused with lactated Ringer solutions at a rate of 2 microl/min. In both normothermia and during whole body heating via a water perfused suit, dialysate from these membranes were obtained and analyzed for NO using the chemiluminescence technique. In six of these subjects, after the heat stress, the membranes were perfused with a 1 M solution of acetylcholine to stimulate NO release. Dialysate from these trials was also assayed to quantify cutaneous interstitial NO concentration. Whole body heating increased skin temperature from 34.6 +/- 0.2 to 38.8 +/- 0.2 degrees C (P 0.05). After the heat stress, administration of acetylcholine in the perfusate significantly increased skin blood flow (128 +/- 6 perfusion units) relative to both normothermic and heat stress values and significantly increased NO concentration in the dialysate (15.8 +/- 2.4 microM). These data suggest that whole body heating does not increase cutaneous interstitial NO concentration in forearm skin. Rather, NO may serve in a permissive role in facilitating the effects of an unknown neurotransmitter, leading to cutaneous vasodilation during a heat stress.

    Cutaneous ciliated cyst was described as a painless cyst occurring on the lower limbs of women between the ages of 15 and 30 years. The cysts are typically lined by ciliated cuboidal to columnar epithelium with pseudostratified areas and focal squamous metaplasia is occasionally present. Immunohistochemical studies have demonstrated that the cysts are PR and ER positive, similar to the epithelia of the fallopian tubes. However, outliers of cutaneous ciliated cysts, including those in male patients and in unexpected locations such as the scalp, finger, and scapular area, have been reported. Thus, some hypotheses have been proposed including the Mullerian heterotopias, ciliated metaplasia of eccrine sweat glands, and embryonic remnants of the cloacal membrane. We report a rare case of cutaneous ciliated cyst on the left shoulder of a 7-year-old boy and this is the eighth case of cutaneous ciliated cyst in male patients. Moreover, through reviewing the articles, we try to propose the classification of the cutaneous ciliated cysts into the cutaneous Mullerian cysts and the ciliated cutaneous eccrine cysts.

    2012-02-01

    Subacute cutaneous lupus erythematosus (SCLE) is a recognised variant of lupus erythematosus (LE), which accounts for 10-15% of all cases of cutaneous LE, occurring most commonly in young to middle-aged white women. Diagnosis is based on the detection of anti-Ro\\/SS-A antibodies in the skin and serum, characteristic clinical and histological cutaneous involvement, and relatively mild systemic involvement. Several unusual variants of SCLE have been reported including erythrodermic SCLE, SCLE with vitiligo-like lesions, acral SCLE and bullous SCLE. Poikoilodermatous SCLE is a recognised but rare variant of SCLE. There are currently only two case reports, comprising five individual cases, in the literature. We present a case of SCLE in which the main clinical findings were an extensive photodistributed poikilodermatous rash and alopecia.

    Primary cutaneous lymphomas (PCLs) are an extremely heterogeneous group of non-Hodgkin lymphomas that manifest in the skin. Their diagnosis is complex and based on clinical lesion type and evaluation of findings on light microscopic examination, immunohistochemistry and molecular analysis of representative skin biopsies. The evaluation, classification, and staging system is unique for mycosis fungoides (MF) and Sézary syndrome (SS), the most common subtypes of cutaneous T-cell lymphoma (CTCL) versus the other subtypes of Non-MF/Non-SS CTCL and the subtypes of cutaneous B-cell lymphoma (CBCL). Since current treatment is stage-based, it is particularly important that the correct diagnosis and stage be ascertained initially. The purpose of this article is to review the current evaluation, diagnosis, classification, staging, assessment techniques, and response criteria for the various types of both T-cell and B-cell PCLs.

    Full Text Available Sarcoidosis is a Greek word (Sarco means flesh and Eido means type or like. Cutaneous sarcoidosis occurs in up to one third of patients with systemic sarcoidosis. This disease is characterised by the presence of non – caseating epitheloid cell granulomas in the skin. Cutaneous sarcoidosis presents as a diagnostic challenge to the dermatopathologists due to its varied presentations and almost identical histologic pictures. Hence, exclusion of infectious causes and compatibility with clinical and radiologic picture serve as significant criteria to come up to a diagnosis. Sometimes; skin lesions are the first manifestation of systemic sarcoidosis. This is not a contagious or allergic disease. There is a risk of development of systemic manifestations at a later date; for which a close follow up is a must. We are presenting a case of cutaneous sarcoidosis, which later on progress to sarcoidosis with systemic manifestations.

    Pleuroparenchymal fibroelastosis (PPFE) is a rare progressive disease that manifests as parenchymal fibrosis of the upper lobe and pleura. Approximately 100 cases have been reported. Cutaneous manifestations of PPFE have not previously been described. Diagnosis is dependent on histologic identification of fibrosis with atypical elastic fibers, necessitating an invasive peripheral lung wedge biopsy.A 68-year-old male with a history of pleuroparenchymal fibroelastosis presented with an asymptomatic, telangiectatic erythematous eruption on bilateral lower extremities. Biopsies demonstrated a subtle perivascular infiltrate with marked increase in atypical elastic fibers, similar to the elastosis in the patient's lungs.This is the first documented case of cutaneous manifestations in PPFE. Clinicians need to be aware that cutaneous eruptions clinically simulating telangiectasia macularis eruptiva perstans but lacking a mast cell infiltrate histologically, may have increased abnormal elastic fibers. Thus, early recognition of these lesions in patients with an undefined restrictive lung disorder, may facilitate the diagnosis of PPFE in some patients.

    Besides their deleterious action on cardiac muscle, anthracycline-type cytostatic agents exert significant neurotoxic effects on primary sensory neurons. Since cardiac sensory nerves confer protective effects on heart muscle and share common traits with cutaneous chemosensitive nerves, this study examined the effects of cardiotoxic doses of adriamycin on the function and morphology of epidermal nerves. Sensory neurogenic vasodilatation, plasma extravasation, and the neural CGRP release evoked by TRPV1 and TRPA1 agonists in vitro were examined by using laser Doppler flowmetry, the Evans blue technique, and ELISA, respectively. Carrageenan-induced hyperalgesia was assessed with the Hargreaves method. Immunohistochemistry was utilized to study cutaneous innervation. Adriamycin treatment resulted in profound reductions in the cutaneous neurogenic sensory vasodilatation and plasma extravasation evoked by the TRPV1 and TRPA1 agonists capsaicin and mustard oil, respectively. The in vitro capsaicin-, but not high potassium-evoked neural release of the major sensory neuropeptide, CGRP, was markedly attenuated after adriamycin treatment. Carrageenan-induced inflammatory hyperalgesia was largely abolished following the administration of adriamycin. Immunohistochemistry revealed a substantial loss of epidermal TRPV1-expressing nociceptive nerves and a marked thinning of the epidermis. These findings indicate impairments in the functions of TRPV1 and TRPA1 receptors expressed on cutaneous chemosensitive nociceptive nerves and the loss of epidermal axons following the administration of cardiotoxic doses of adriamycin. Monitoring of the cutaneous nociceptor function in the course of adriamycin therapy may well be of predictive value for early detection of the deterioration of cardiac nerves which confer protection against the deleterious effects of the drug.

  14. Radiotherapy for cutaneous cancers with xeroderma pigmentosum

    International Nuclear Information System (INIS)

    Purpose. - To analyze the therapeutic results of cutaneous cancers on xeroderma pigmentosum through a series of 15 patients treated by radiotherapy. Patients and methods. - Between 1993 and 2006, 15 patients with xeroderma pigmentosum and having cutaneous cancers were treated in the Radiotherapy Department of university hospital Habib-Bourguiba of Sfax in Tunisia. Seventy-three percent of the cases occurred in male patients and the mean age of appearance of the first tumour was 18.2 years. Tumour histology was squamous cell carcinoma in 74% of the cases. The total number of cutaneous tumours was 84. Ten patients had a surgical resection. Four patients did not respond to chemotherapy. The modality of irradiation was decided according to the size, thickness and localization of the tumour. The dose of radiotherapy was 60 Gy or equivalent with classic irradiation. Results. - The total number of lesions treated with radiotherapy was 64. Forty-three lesions were treated with contact-therapy, ten with brachytherapy and 11 with cobalt-therapy. The following acute complications were observed: cutaneous infection (53.3% of patients), radio-epithelitis (80% of patients) and necroses (33.3% of patients). Evaluation after treatment showed a clinical complete remission in 73% of the cases. Late effects were noted in seven cases: telangiectasia and cutaneous atrophy. A recurrence in the irradiated zone was observed in one case. A nodal metastasis was observed in two cases. Another patient presented lung metastases. After a median follow up of 37.2 months, four patients died, seven are alive with cutaneous cancer and four are alive with complete remission. Conclusion. - Radiotherapy is a possible and effective therapeutic alternative. Dose and methods are not defined for xeroderma pigmentosum. (authors)

    Full Text Available Background: Cutaneous vasculitis presents as a mosaic of clinical and histological findings. Its pathogenic mechanisms and clinical manifestations are varied. Aims: To study the epidemiological spectrum of cutaneous vasculitides as seen in a dermatologic clinic and to determine the clinico-pathological correlation. Methods: A cohort study was conducted on 50 consecutive patients clinically diagnosed as cutaneous vasculitis in the dermatology outdoor; irrespective of age, sex and duration of the disease. Based on the clinical presentation, vasculitis was classified according to modified Gilliam′s classification. All patients were subjected to a baseline workup consisting of complete hemogram, serum-creatinine levels, serum-urea, liver function tests, chest X-ray, urine (routine and microscopic examination besides antistreptolysin O titer, Mantoux test, cryoglobulin levels, antineutrophilic cytoplasmic antibodies and hepatitis B and C. Histopathological examination was done in all patients while immunofluorescence was done in 23 patients. Results: Out of a total of 50 patients diagnosed clinically as cutaneous vasculitis, 41 were classified as leukocytoclastic vasculitis, 2 as Heinoch−Schonlein purpura, 2 as urticarial vasculitis and one each as nodular vasculitis, polyarteritis nodosa and pityriasis lichenoid et varioliforme acuta. Approximately 50% of the patients had a significant drug history, 10% were attributed to infection and 10% had positive collagen workup without any overt manifestations, while 2% each had Wegener granulomatosis and cryoglobulinemia. No cause was found in 26% cases. Histopathology showed features of vasculitis in 42 patients. Only 23 patients could undergo direct immunofluorescence (DIF, out of which 17 (73.9% were positive for vasculitis. Conclusions: Leukocytoclastic vasculitis was the commonest type of vaculitis presenting to the dermatology outpatient department. The workup of patients with cutaneous vasculitis

    Full Text Available BACKGROUND A wide range of immunologic and non-immunologic causes can lead to the formation of a granuloma. The aetiological agent and immunological status of the host determines the clinical presentation of these chronic skin lesions. However, diagnosis often becomes intricate as different clinical types present with morphological similarities, which gets further complicated by time and presumptive therapy. AIMS To study the incidence and clinical pattern of cutaneous granulomas; their relationship with age, sex, trauma and determine the importance of laboratory tests, specially histopathology in confirming aetiological diagnosis. SETTINGS AND DESIGN Cross-sectional study, based on hospital records. METHODS AND MATERIAL The study was from OPD records of Department of Dermatology and Venereology. All patients who had attended with clinically suspected cutaneous granulomatous lesions and underwent investigative procedures over a one-year period were included in the study. The relevance of the investigative procedures used, especially histopathology in arriving at the final diagnosis was established. Statistical analysis used: Descriptive statistical analysis and Chi-square test whenever appropriate. RESULTS AND CONCLUSIONS A total of 300 cases of cutaneous granuloma were included in the study. There was a male preponderance. The commonest cutaneous granuloma encountered was leprosy followed by fungal and tubercular granuloma. Less frequently encountered forms were syphilis, foreign body, parasitic, lymphogranuloma venereum, actinomycosis, rhinoscleroma, donovanosis and granulomatous mycosis fungoides. A total of 83.39% cases showed clinic-histopathological correlation. Cutaneous granulomas cause diagnostic difficulty due to clinical diversity and mimicry. Cutaneous granulomas of similar origin can present with varied clinical presentations, while those from different backgrounds can have similar presentations. A histopathological examination

    p6 report two cases of cutaneous allergy to human (recombinant DNA) insulin. Each patient had a history of systemic allergic reactions to porcine insulin and was at least as reactive to human as to porcine insulin by end-point cutaneous titration. Both patients' insulin allergy was managed with animal insulins and both have done well. Our experience with these two patients indicates that human insulin (rDNA) should not be expected to be efficacious in all patients with systemic allergy to insulin. PMID:6366262

    During the past century, organ transplantation has delivered the miracle of life to more than 500,000 patients in need. Secondary malignancies have developed as an unforeseen consequence of intense immunosuppressive regimens. Cutaneous malignancies have been recognized as the most frequent cancer that arises post-transplantation. Among organ transplant recipients (OTRs), skin cancer is a substantial cause of morbidity and potential mortality. The authors discuss epidemiology and clinical presentation of cutaneous malignancies; associated risk factors; recommendation for the care of immunosuppressed OTRs, and emerging therapies on the horizon.

    Sporotrichosis is a subcutaneous and exceptionally deep mycosis caused by a dimorphic fungus, Sporothrix schenckii. Itraconazole is a triazole derivative leading to good results in the treatment of sporotrichosis. Patients with cutaneous sporotrichosis proven with mycological tests (direct examination and culture) were enrolled. All patients underwent laboratory tests (at baseline and on a monthly basis) and received oral itraconazole 400 mg/day for one week with a 3-week break (pulses); thereafter the drug was administered as pulses until clinical and mycological cure was achieved. Five patients with sporotrichosis were enrolled, 4 with cutaneous lymphangitic form and one with fixed cutaneous form. Clinical and mycological cure was achieved in 4/5 cases (80%), with a mean number of pulses of 3.5. No patient had side effects and no laboratory test abnormalities occurred. Intermittent or pulsed itraconazole was effective in treating cutaneous sporotrichosis. It may be considered as a new treatment choice that entails an important reduction in total medication use.

    Popov, Dmitri; Maliev, Slava

    Cutaneous injury is an important complication of a general or local acute irradiation. A type of a skin and tissues lesions depends on a type, intensity, and period of irradiation. Also, the clinical picture, signs, and manifestations of the cutaneous syndrome depend on a type of the radiation toxins circulated in lymph and blood of irradiated mammals. Radiation Toxins were isolated from lymph of the mammals that were irradiated and developed different forms of the Acute Radiation Syndromes (ARS) -Cerebrovascular, Cardiovascular, Gastrointestinal, and Hematopoietic. Radiation Toxins can be divided into the two important types of toxins (Neu-rotoxins and Hematotoxins) or four groups. The effects of Radiation Neurotoxins include severe damages and cell death of brain, heart, gastrointestinal tissues and endothelial cells of blood and lymphatic vessels. The hematotoxicity of Hematotoxic Radiation Toxins includes lym-phopenia, leukopenia, thrombocytopenia, and anemia in the blood circulation and transitory lymphocytosis and leukocytosis in the Central Lymphatic System. In all cases, administration of the Radiomimetics (Radiation Toxins) intramuscularly or intravenously to healthy, radiation naive mammals had induced and developed the typical clinical manifestations of the ARS. In all cases, administration of Radiomimetics by subtoxic doses had demonstrated development of typical clinical signs of the cutaneous syndrome such as hair loss, erythema, swelling, desqua-mation, blistering and skin necrosis. In animal-toxic models, we have activated development of the local skin and tissue injury after injection of Radiation Toxins with cytoxic properties.

    Full Text Available We will revisit the dual role of the immune system in controlling and enabling tumor progression, known as cancer immunoediting. We will go through the different phases of this phenomenon, exposing the most relevant evidences obtained from experimental models and human clinical data, with special focus on Cutaneous Melanoma, an immunogenic tumor per excellence. We will describe the different immunotherapeutic strategies employed and consider current models accounting for tumor heterogeneity. And finally, we will propose a rational discussion of the progress made and the future challenges in the therapeutics of Cutaneous Melanoma, taking into consideration that tumor evolution is the resulting from a continuous feedback between tumor cells and their environment, and that different combinatorial therapeutic approaches can be implemented according to the tumor stage.

    Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis defined by heterogeneous multiorgan involvement. Due to the rarity of this disease strong evidence-based therapies have yet to be established and prognosis has previously been considered to be poor, with more than half of patients dying within 3 years of initial presentation. We describe an 86-year-old woman with a 34-year history of extensive cutaneous and internal nodules with typical pathological and immunophenotypical (CD68(+) /CD1a(-) ) features of ECD without evidence of the BRAF V600E mutation. The cosmetic appearance of cutaneous nodules and hoarse voice caused by vocal cord nodules has been managed surgically. More aggressive therapies reported for ECD were trialled for this patient, such as radiotherapy and interferon-α, with no response. This case demonstrates a relatively good prognosis in ECD that has been managed conservatively. PMID:25639756

To our knowledge, only one previous article has reported pathologic and crystallographic studies on calcifications of the skin resulting from dialysis oxalosis. We speculate that vitamin C supplements, liberal tea consumption, an increased serum ionized calcium concentration, and the long duration of hemodialysis contributed to the production of these deposits.

    Sulfur mustard is an alkylating chemical warfare agent that primarily affects the eyes, skin, and airways. Sulfur mustard injuries can take several months to heal, necessitate lengthy hospitalizations, and result in significant cosmetic and/or functional deficits. Historically, blister aspiration and/or deroofing (epidermal removal), physical debridement, irrigation, topical antibiotics, and sterile dressings have been the main courses of action in the medical management of cutaneous sulfur m...

    In patients with cutaneous openings, sinograph and fistulography an usually performed. Fistulae in the head/neck region and perineum are seldom life-threatening while enterocutaneous fistulae involving the small bowel can be a serious threat due to loss of fluid. Radiology contributes to the preoperative examination of these patients. Fistulography outlines communications to the gastrointestinal tract, pleura, joints and other underlying crucial structures. Involved bowel segments are further demonstrated with barium examination. (orig.)

    Systemic lupus erythematosus (SLE) is a multiorgan autoimmune disease of unknown etiology with many clinical manifestations. The skin is one of the target organs most variably affected by the disease. The American College of Rheumatology (ACR) established 11 criteria as a classificatory instrument to operationalise the definition of SLE in clinical trials. They were not intended to be used to diagnose individuals and do not do well in that capacity. Cutaneous lesions account for four of these...

    A 46-year-old man who had been treated with azathioprine and budesonide for Crohn's disease for the past eight years developed a purulent skin condition on the right ring finger. Despite surgical drainage and treatment with amoxicillin and flucloxacillin, the condition spread itself over the hand and lower arm, partly per continuum and partly in jumps. The patient did not feel ill and there were no systemic symptoms. Ultimately, Nocardia asteroides was cultured from the wound and complete cure was achieved after 8 months' treatment with co-trimoxazole. Infections with Nocardia spp. are rare but may occur more often and run a more fulminant course in patients under treatment with immunosuppressants. Cutaneous nocardiosis generally has a characteristic lymphogenous spreading pattern, but an atypical picture with pustules, pyoderma, cellulitis or abscess formation is also possible. In non-cutaneous nocardiosis there is usually pneumonia or lung abscess, possibly with secondary haematogenous spread to the central nervous system or skin. Culturing Nocardia requires more time than usual but can be promoted by special culture media. Treatment of the infection with co-trimoxazole is the method of choice and is almost always successful in cases of cutaneous nocardiosis.

    Full Text Available A 65-year-old male with a history of smoking since 30 years presented with breathlessness, hemoptysis, multiple swellings all over the body, and weakness in September 2010 at our hospital. Clinically, a diagnosis of chronic obstructive pulmonary disease (COPD with cutaneous lymphoma or soft tissue tumor was made. Chest X-ray (CXR and computed tomography (CT scan revealed a neoplastic lesion in the right lung with secondary cavitation. Biopsy of the cutaneous nodules showed metastatic deposits from squamous cell carcinoma. Metastatic skin cancer is a relatively rare complication of internal malignancy. The clinical features of metastatic skin disease vary enormously. They may present as erysipeloid, sclerodermoid, alopecia neoplastica or in an inflammatory or bullous form or as multiple nodules as in our case. A high index of suspicion for metastatic deposits is required in an elderly male patient who is a known case of lung cancer or even one who is a chronic smoker and presents with such cutaneous lesions.

    Acromegaly is a systemic syndrome caused by overproduction of growth hormone. The syndrome affects cutaneous, endocrine, cardiovascular, skeletal, and respiratory systems. Cutaneous manifestations of acromegaly are various, usually being the first presenting findings of the disease. Forty-nine patients with acromegaly, followed-up at a tertiary referral hospital, underwent dermatological examination. There were 27 (55.1%) female and 22 (44.9%) male patients. The age at onset of the disease was older in females than males (P=0.045). Most patients had acral enlargements, large triangular nose, coarse face, thickened lower lip, and prognathism. Fourteen (28.6%) patients had multiple cherry angiomas, five (10.2%) had varicose veins in lower limbs, and two (4.1%) had psoriasis. In conclusion, a wide spectrum of cutaneous symptoms and features may be associated with acromegaly. Detailed dermatological examination of patients with acromegaly should be an essential component of systemic evaluation. Future prospective studies investigating the relationships between changes in skin signs, hormone levels, and response to treatments may help understand details of skin involvement in acromegaly.

    Cutaneous leishmaniasis of the New World, in particular when caused by Leishmania (L.) braziliensis, harbours the risk of lymphogenic as well as hematogenic dissemination. This may result in mucocutaneous leishmaniasis causing severe destruction of orofacial structures. Dissemination may occur years after the disappearance of the skin lesions. In contrast, cutaneous leishmaniasis of the old world, is typically restricted to the site of inoculation. Therefore, a conservative diagnostic and therapeutic approach is usually sufficient. Infections acquired in the new world should be treated systemically, if infection with Leishmania (Viannia) braziliensis complex cannot be excluded. Here we report on three Austrian soldiers, who, weeks after having participated in an international jungle patrol course in Belize, presented themselves with multiple ulcers on the upper limbs. Diagnosis of cutaneous leishmaniasis was made based upon histological evaluation of biopsies taken from several ulcers revealing the presence of leishmanial bodies, and detection of amastigote leishmania in smears of material obtained from the ulcers. As species phenotyping could not be performed, infection with L. brasiliensis as well as progression into a mucocutaneous form were possible, demanding systemic therapy. Several treatment options including local cryotherapy with liquid nitrogen, paromomycin (Humatis Pulvis, Parke-Davis) 15% topically or oral fluconazole (Diflucan, Pfizer) 200 mg/d were applied, but showed no effect. Hence, a systemic therapy with intravenous pentamidine (Pentacarinat, Gerot), three times in total, 3-4 mg/kg body weight each, led to a complete regression of the lesions within four weeks.

    Full Text Available An approximately 4-year-old castrated male, Saanen cross goat presented to the Colorado State University Veterinary Teaching Hospital for evaluation and removal of a 22 cm × 22 cm, dark red, thickened, and crusted cutaneous lesion along the left ventrolateral thorax. An initial incisional biopsy performed approximately 8 weeks earlier was suspicious for cutaneous hemangiosarcoma. Surgical excision was deemed to be the most appropriate treatment option for this goat. A complete physical exam, complete blood count, and chemistry profile were performed and results were within normal limits. Thoracic radiographs and abdominal ultrasound were performed to rule out metastatic disease and comorbid conditions; no metastatic lesions or other abnormalities were observed. En bloc surgical excision of the affected skin was performed and the entire tissue was submitted for histopathology. A final diagnosis of cutaneous hemangiolipoma was reached upon extensive sectioning and histologic examination of the larger tissue specimen. The goat recovered well from surgery and has had no further complications up to 9 months postoperatively. To our knowledge, this is the first case report of a hemangiolipoma in a goat and surgical excision for such lesions appears to be a viable treatment method.

    A 2-week-old crossbred male piglet with numerous congenital, variably sized macules, plaques, and papules distributed all over the body was submitted for necropsy. Significant gross and histological lesions were restricted to the skin. On light microscopic examination, these cutaneous lesions corresponded to dermal and/or subcutaneous masses composed of spindle-shaped to round cells that multifocally contained hemosiderin; epidermotropism was not observed. Immunohistochemically, the neoplastic cells were strongly positive for CD204; moderately positive for CD163, lysozyme, and vimentin; and negative for Mac 387, α-1-antitrypsin, S-100 protein and E-cadherin; frozen tissues were not available for CD1a and CD11c. Transmission electron microscopic examination of sections from formalin-fixed tissues did not reveal Birbeck's granules. The clinical, morphological, and immunohistochemical results were consistent with a congenital cutaneous histiocytosis of non-Langerhans cell origin. The condition most resembled juvenile xanthogranuloma in humans, a generally skin-limited non-Langerhans histiocytic disorder that can be congenital. Cutaneous and/or systemic histiocytic disorders are well characterized in dogs and have been described in cats, and a case with some similarities to ours has been reported in a neonatal piglet, but this is to our knowledge the first immunohistochemically supported report of histiocytosis in the pig and congenital histiocytosis in animals.

    Full Text Available Minor surgery is a general surgical procedure that applied with minimally invasive procedures and short duration, done in a superficial or just the affected tissue.  This technique is normally only requires a local anaesthetic and only has minimal  risk or complications. There are many cases that could be dealt with minor surgery one is veruka. Veruka or known as cutaneous warts is a disease that is often complained in children and adults. Veruka being estimated to occur until over 10% in children and young adults. Largest incident occurred in range of age 12 to 16 years. Veruka occurs more frequently in women than men. The peak incidence occur of age 13 years on women and 14.5 years in males. Salicylic acid and cryosurgery therapy are two of the most frequently performed in the treatment of cutaneous warts. Salicylic acid is therapy  for cutaneous warts who recently had already started replaced by cryosurgery because it is relatively easy to do and faster recovery.

    Pancreatic cancer is one of the most lethal human cancers and continues to be a major unsolved health problem as we enter the 21st century. This is the case despite advances in imaging technology and surgical management. Indeed, 80-90% of pancreatic cancers are diagnosed either at the locally advanced stage or metastatic stage. Cutaneous metastases originating from pancreatic cancer are relatively rare. The most common site of cutaneous metastasis is the umbilicus, and it is known as the Sister Joseph's nodule. Very few patients have been reported with cutaneous lesions disclosing pancreatic carcinoma at sites other than the umbilical area. To our knowledge, there were no previous reports on cutaneous pancreatic metastasis in Egypt. This is a report of a patient with cutaneous pancreatic metastases at the neck, followed by a review of reported non-umbilical cutaneous metastases from pancreatic carcinoma in the literature.

    Diagnosis of leishmaniasis in immunosuppressed patients may be a serious challenge for physicians because of the major clinical and laboratory differences with immunocompetent patients. In immunosuppressed patients, the disease is characterized usually by disseminated visceral involvement, atypical cutaneous lesions and persistent negativity of diagnostic tests. Here, we report an eight-yr-old liver transplant recipient with concomitant cutaneous and visceral leishmaniasis in whom the cutaneous lesion led to the diagnosis of systemic involvement.

    The composition of cutaneous lesions from 158 patients with confirmed cutaneous T cell lymphoma, 91 patients with suspected cutaneous T cell lymphoma, and 145 patients with lymphoid disorders other than cutaneous T cell lymphoma was quantitated in situ with the use of commercially available murine monoclonal antibodies that identify the Pan T, T-helper/inducer (Th), T cytotoxic/suppressor (Ts), and Pan B lymphocyte subsets. On average, cutaneous infiltrates of confirmed cutaneous T cell lymphoma were found to contain significantly more Th and less Ts or Pan B cells compared to benign lymphoid disorders. Moreover, when analyzed in terms of the type of lesion examined by biopsy, the absolute amount of Th cells progressively expands with increasing magnitudes of infiltrate in the dermis while the amount of Ts and Pan B cells remains relatively constant among lesions. A useful diagnostic criterion (anti-Leu 1/4 greater than or equal to 70% and anti-Leu 3a/anti-Leu 2a ratio greater than or equal to 6) correctly discriminated between cutaneous T cell lymphoma and non-cutaneous T cell lymphoma in 87.5% of cases. A positive immunodiagnostic result also may be useful for the prediction of subsequent histopathologic confirmation of cutaneous T cell lymphoma in patients who have suspect lymphoid infiltrates, such as alopecia mucinosis or idiopathic generalized erythroderma, when first seen. With the use of multivariate analysis, stage and possibly the percentage of Th cells within the T cell component in cutaneous infiltrates were covariates with significant relationships to survival in patients with confirmed cutaneous T cell lymphoma. In addition, Ts cells in infiltrates did not correlate significantly with observed responses to topical treatment and subsequent course in pretumorous mycosis fungoides. These results indicate that Ts cells play little biologic role in modifying the natural history of cutaneous T cell lymphoma.

    Full Text Available Cutaneous manifestations of Lyme borreliosis in Europe include erythema migrans (EM and acrodermatitis chronica atrophicans (ACA; the most common non-cutaneous manifestations are Lyme neuroborreliosis (LNB and Lyme arthritis. The purpose of this study was to evaluate the gender distribution of patients with these clinical manifestations of Lyme borreliosis. Data on gender were obtained from the clinical records of patients with Lyme borreliosis aged ≥15 years who had been evaluated at the University Medical Center Ljubljana, Ljubljana, Slovenia. Among 10,539 patients diagnosed with EM, 6,245 (59.3% were female and among 506 ACA patients 347 (68.6% were female. In contrast, among the 60 patients with Lyme arthritis only 15 (25% were female (p<0.0001 for the comparison of gender with EM or ACA and among the 130 patients with LNB only 51 (39.2% were females (p<0.0001for the comparison of gender with EM or ACA. Although the proportion that was female in the LNB group was greater than that of patients with Lyme arthritis, this difference did not reach statistical significance (p = 0.10. Although older individuals are more likely to be female in the general Slovenian population, the age of patients with cutaneous versus non-cutaneous manifestations was not the explanation for the observed differences in gender. In conclusion, patients with cutaneous manifestations of Lyme borreliosis were predominantly female, whereas those with non-cutaneous manifestations were predominantly male. This provocative finding is unexplained but may have direct relevance to the pathogenesis of Lyme borreliosis.

    Purpose. - To analyze the therapeutic results of cutaneous cancers on xeroderma pigmentosum through a series of 15 patients treated by radiotherapy. Patients and methods. - Between 1993 and 2006, 15 patients with xeroderma pigmentosum and having cutaneous cancers were treated in the Radiotherapy Department of university hospital Habib-Bourguiba of Sfax in Tunisia. Seventy-three percent of the cases occurred in male patients and the mean age of appearance of the first tumour was 18.2 years. Tumour histology was squamous cell carcinoma in 74% of the cases. The total number of cutaneous tumours was 84. Ten patients had a surgical resection. Four patients did not respond to chemotherapy. The modality of irradiation was decided according to the size, thickness and localization of the tumour. The dose of radiotherapy was 60 Gy or equivalent with classic irradiation. Results. - The total number of lesions treated with radiotherapy was 64. Forty-three lesions were treated with contact-therapy, ten with brachytherapy and 11 with cobalt-therapy. The following acute complications were observed: cutaneous infection (53.3% of patients), radio-epithelitis (80% of patients) and necroses (33.3% of patients). Evaluation after treatment showed a clinical complete remission in 73% of the cases. Late effects were noted in seven cases: telangiectasia and cutaneous atrophy. A recurrence in the irradiated zone was observed in one case. A nodal metastasis was observed in two cases. Another patient presented lung metastases. After a median follow up of 37.2 months, four patients died, seven are alive with cutaneous cancer and four are alive with complete remission. Conclusion. - Radiotherapy is a possible and effective therapeutic alternative. Dose and methods are not defined for xeroderma pigmentosum. (authors)

    Full Text Available Cutaneous nocardiosis is a rare disease, only a few cases of which have been reported from the world as well as in India. This infection, when in the lymphocutaneous form, may clinically resemble sporotrichosis, hence causing a diagnostic dilemma. Here, we report a case of primary cutaneous, sporotrichoid pattern of cutaneous nocardiosis caused by Nocardia asteroides in immunocompetent host. The patient was a 32-year-old farmer, with no predisposing factors, who presented with cutaneous nocardiosis. The diagnosis was confirmed by culture of the biopsy, after which the patient was treated successfully with antibacterial agents.

    Full Text Available A cutaneous horn is a general name for cornified material protruding from skin. On the other hand, polydactyly is a common congenital anomaly of the hand and foot which is characterized by extra finger or toe. A cutaneous horn might mimick polydactyly by resembling an extra toe. Hereby, we present a 72-year-old white Caucasian male with an extra toe-like projection on his fourth toe. Initially, polydactyly was suspected, however a cutaneous horn was also considered. The lesion was surgically removed. The histopathological examination of the specimen revealed hyperkeratosis, and thus confirmed the  lesion to be a cutaneous horn.

    Directory of Open Access Journals (Sweden)

    Bilgen Gençler

    2016-01-01

    Full Text Available The incidence of melanoma has recently been increasing. BRAF mutations have been found in 40–60% of melanomas. The increased activity of BRAF V600E leads to the activation of downstream signaling through the mitogen-activated protein kinase (MAPK pathway, which plays a key role as a regulator of cell growth, differentiation, and survival. The use of BRAF inhibitors in metastatic melanoma with BRAF mutation ensures clinical improvement of the disease. Vemurafenib and dabrafenib are two selective BRAF inhibitors approved by the Food and Drug Administration (FDA. Both drugs are well tolerated and successfully used in clinical practice. However, some adverse reactions have been reported in patients in the course of treatment. Cutaneous side effects are the most common adverse events among them with a broad spectrum. Both the case reports and several original clinical trials reported cutaneous reactions during the treatment with BRAF inhibitors. In this review, the common cutaneous side effects of BRAF inhibitors in the treatment of metastatic melanoma with BRAF V600E mutation were reviewed.

    1981-09-01

    The purpose of this study was to investigate the participation of lipid peroxide (LP) in some skin damages due to ultraviolet (UV) irradiation. Results obtained were as follows. 1) Long wave UV (UVA) was irradiated to rat skin homogenates. The levels of LP increased linearly with irradiation time. 2) When 8-methoxypsoralen was added to the homogenates prior to UVA irradiation, however, the LP levels showed no increase. 3) Various anti-oxidative agents were added to homogenates and UVA was irradiated. Only Vit. E reduced the LP levels in proportion to its concentrations. 4) Anti-oxidative agents were given to rats which were then exposed to PUVA (8-methoxypsoralen plus UVA) treatment. Among them, administration of Vit. E and pantethine was associated with reduction of serum and cutaneous LP levels with only slight histologic changes in the involved skin. 5) Vit. E deficient rats were treated with PUVA. In these models, cutaneous LP levels raised from 24 hours to 96 hours after PUVA treatment and histologic changes such as vacuolization, blister formation and cell degeneration were remarkable. From the above data, it became evident that lipid peroxidation took place in skin tissue per se and even in the UVA wave length region. After PUVA treatment, cutaneous LP levels correlated relatively well with histologic changes of the involved skin. The results suggested that LP played a certain role in skin damages due to UV.

    The prevalence of allergies, including rhinitis, eczema, and anaphylaxis, is rising dramatically worldwide. This increase is especially problematic in children who bear the greatest burden of this rising trend. Increasing evidence identifies neutrophils as primary perpetrators of the more severe and difficult to manage forms of inflammation. A newly recognized mechanism by which neutrophils are recruited during the early phase of histamine-induced inflammation involves the sphingosine kinase (SK)/sphingosine-1-phosphate axis. This study examines whether topical application of fingolimod, an established SK/sphingosine-1-phosphate antagonist already in clinical use to treat multiple sclerosis, may be repurposed to treat cutaneous inflammation. Using two mouse models of ear skin inflammation (histamine- and IgE-mediated passive cutaneous anaphylaxis) we topically applied fingolimod prophylactically, as well as after establishment of the inflammatory response, and examined ear swelling, SK activity, vascular permeability, leukocyte recruitment, and production of proinflammatory mediators. The present study reveals that when applied topically, fingolimod attenuates both immediate and late-phase responses to histamine with reduced extravasation of fluid, SK-1 activity, proinflammatory cytokine and chemokine production, and neutrophil influx and prevents ear swelling. Intravital microscopy demonstrates that histamine-induced neutrophil rolling and adhesion to the postcapillary venules in the mouse ears is significantly attenuated even after 24 h. More importantly, these effects are achievable even once inflammation is established. Translation into humans was also accomplished with epicutaneous application of fingolimod resolving histamine-induced and allergen-induced inflammatory reactions in forearm skin. Overall, this study demonstrates, to our knowledge for the first time, that fingolimod may be repurposed to treat cutaneous inflammation. PMID:27001955

    Cutaneous collagenous vasculopathy is a rare microangiopathy first described by Salama and Rosenthal in 2000. Several cases have been reported to date, describing distinct histological findings of thick hyaline collagenous blood vessel walls in the superficial dermis. Clinical confusion can arise with generalised essential telangiectasia. We report a case occurring in a 76-year-old woman who presented with a 2-year history of a telangiectatic rash progressing from her knees upwards. The diagnosis was confirmed on skin biopsy and treatment with pulsed dye laser was later initiated at the patient's request. PMID:25872701

    2011-01-01

    Full Text Available Drug hypersensitivity is an unpredictable, immunologically mediated adverse reaction, clustered in a genetically predisposed individual. The role of "hapten concept" in immune sensitization has recently been contested by the "pharmacological interaction" hypothesis. After completion of the "human genome project" and with the availability of high-resolution genotyping, genetic susceptibility to hypersensitivity for certain drugs has been proved beyond doubt though the trend is ethnicity and phenotype dependent. Application of this newly acquired knowledge may reduce or abolish the morbidity and mortality associated with cutaneous drug hypersensitivity.

    Prattichizzo, D; Pacchierotti, C; Rosati, G

    2012-01-01

    A novel sensory substitution technique is presented. Kinesthetic and cutaneous force feedback are substituted by cutaneous feedback (CF) only, provided by two wearable devices able to apply forces to the index finger and the thumb, while holding a handle during a teleoperation task. The force pattern, fed back to the user while using the cutaneous devices, is similar, in terms of intensity and area of application, to the cutaneous force pattern applied to the finger pad while interacting with a haptic device providing both cutaneous and kinesthetic force feedback. The pattern generated using the cutaneous devices can be thought as a subtraction between the complete haptic feedback (HF) and the kinesthetic part of it. For this reason, we refer to this approach as sensory subtraction instead of sensory substitution. A needle insertion scenario is considered to validate the approach. The haptic device is connected to a virtual environment simulating a needle insertion task. Experiments show that the perception of inserting a needle using the cutaneous-only force feedback is nearly indistinguishable from the one felt by the user while using both cutaneous and kinesthetic feedback. As most of the sensory substitution approaches, the proposed sensory subtraction technique also has the advantage of not suffering from stability issues of teleoperation systems due, for instance, to communication delays. Moreover, experiments show that the sensory subtraction technique outperforms sensory substitution with more conventional visual feedback (VF).

    Cutaneous applications are gaining popularity in the treatment of cutaneous pain and of painful disorders in joints and muscle. The low pH-pain model in human skin has previously been able to demonstrate the effects of NSAIDs in dose-dependent manner and to establish time-effect relationships. We examined the analgesic action of ibuprofen after cutaneous application and compared the effects with oral administration. The two studies (with n = 12 subjects each) were performed in a double-blind, randomized fashion with a 1-week cross-over interval. In study 1 volunteers received intradermal infusions with phosphate buffered saline solution of pH 5.2 and received either 800 mg ibuprofen per os and topical placebo, or 4 g of a 5% commercial ibuprofen gel topically applied and oral placebo capsules, respectively. In study 2 the same protocol was applied with painful intramuscular infusion of stronger, isotonic phosphate buffer (pH 5.2). The flow rate of the pH-infusion was individually adjusted to induce pain with a magnitude of 20% on a visual analogue scale (ranging from 'no' (0%) to 'unbearable pain' (100%)). Ibuprofen (S-, R-) plasma levels after oral administrations were measured with HPLC, and after topical applications, by gas chromatography combined with mass spectroscopy to determine plasma levels in the range of ng/ml. In the cutaneous model pain ratings decreased to zero after topical verum gel within 45 min of the observation period of 55 min. Pain reduction after peroral ibuprofen was of the same magnitude, but was achieved within only 30 min. In the muscle model, the commercial ibuprofen gel did not reduce the pain in the acidic muscle. The peroral ibuprofen was less effective in the muscle compared to the skin pain model, although there was a significant progressive pain reduction within 55 min. Reasons for the differential susceptibility of cutaneous vs muscular acidosis pain to ibuprofen remain to be established. PMID:10957700

  8. The Role of Neuromediators and Innervation in Cutaneous Wound Healing.

    Science.gov (United States)

    2016-06-15

    The skin is densely innervated with an intricate network of cutaneous nerves, neuromediators and specific receptors which influence a variety of physiological and disease processes. There is emerging evidence that cutaneous innervation may play an important role in mediating wound healing. This review aims to comprehensively examine the evidence that signifies the role of innervation during the overlapping stages of cutaneous wound healing. Numerous neuropeptides that are secreted by the sensory and autonomic nerve fibres play an essential part during the distinct phases of wound healing. Delayed wound healing in diabetes and fetal cutaneous regeneration following wounding further highlights the pivotal role skin innervation and its associated neuromediators play in wound healing. Understanding the mechanisms via which cutaneous innervation modulates wound healing in both the adult and fetus will provide opportunities to develop therapeutic devices which could manipulate skin innervation to aid wound healing.

    Cutaneous metastases from urothelial carcinoma of the bladder are a rare disease.In previous reports,the most common metastatic cutaneous lesions were non-tender nodules on the abdominal skin.We report a patient with bladder urothelial carcinoma with cutaneous metastases initially presenting as right leg and suprapubic lymphedema.Bladder tumor was the incidental finding by magnetic resonance venography.Urothelial carcinoma (clinical stage Ⅳ) was diagnosed,and chemotherapy was performed.Extensive painful erythematous plaques with an erysipelas-like appearance located on the suprapubic area,chest and abdomen were noted,and cutaneous metastases were confirmed by histopathology.Subsequently,extensive scrotal and prepuce ulcerative changes developed.This paper reports a rare case of extensive cutaneous metastasis of bladder urothelial carcinoma who presented an interesting clinical course.

  10. Diagnosis and therapy of cutaneous radiation syndrome. Individual radiosensitivity assessment in patients undergoing medical exposures presenting severe cutaneous radiation induced lesions

    International Nuclear Information System (INIS)

    Hospital de Quemados del Gobierno de la Ciudad de Buenos Aires (Burn Center) is one of the reference hospitals of the Medical Radiological Emergency Response Network of Argentina. In the frame of an agreement between the Burn Center and the Nuclear Regulatory Authority of Argentina, a research project for an approach based on diagnosis and therapy of cutaneous radiation induced lesions is in progress. Individual radiosensitivity assessment was conducted in patients included in this research protocol that showed acute and/or late cutaneous reactions with grades 3 and 4 of the Toxicity criteria of the Radiation Therapy Oncology Group (RTOG) and the European organization for research and treatment of cancer (EORTC). DNA repair capacity and its kinetics were evaluated in human peripheral blood lymphocytes using alkaline comet assay and micronucleus test. In this paper, two representative cases, in which the research protocol was applied, are presented. Therapeutic response and its correlation with radiosensitivity test results are described. Case 1: female patient undergoing external radiotherapy for invasive ductal breast cancer that presented acute cutaneous radiotoxicity, grade 3 (confluent moist epithelitis, )that led to treatment break. Case 2: male patient undergoing coronary angioplasty (interventional radiology), which developed late cutaneous radiotoxicity, grade 4 (ulceration at the dorsal region). Patients were treated with: topic administration of trolamine and silver sulfadiazine with lidocaine, associated with systemic administration of pentoxiphiline and anti-oxidants. The therapeutic response was evaluated through clinical follow-up, serial photographic record and complementary tests (tele thermography and high frequency ultrasonography). Case 1 response was positive (favorable) with early local recovery and complete remission of signs and symptoms after 5 months. Both MN frequencies and comet assay showed values compatible with normal radiosensitivity

    According to the International Atomic Energy Agency (IAEA), a relatively significant number of radiological accidents have occurred in recent years mainly because of the practices referred to as potentially high-risk activities, such as radiotherapy, large irradiators and industrial radiography, especially in gammagraphy assays. In some instances, severe injuries have occurred in exposed persons due to high radiation doses. In industrial radiography, 80 cases involving a total of 120 radiation workers, 110 members of the public including 12 deaths have been recorded up to 2014. Radiological accidents in industrial practices in Brazil have mainly resulted in development of cutaneous radiation syndrome (CRS) in hands and fingers. Brazilian data include 5 serious cases related to industrial gammagraphy, affecting 7 radiation workers and 19 members of the public; however, none of them were fatal. Some methods of reconstructive dosimetry have been used to estimate the radiation dose to assist in prescribing medical treatment. The type and development of cutaneous manifestations in the exposed areas of a person is the first achievable gross dose estimation. This review article presents the state-of-the-art reconstructive dosimetry methods enabling estimation of local radiation doses and provides guidelines for medical handling of the exposed individuals. The review also presents the Chilean and Brazilian radiological accident cases to highlight the importance of reconstructive dosimetry. (author)

  14. Plasmacytoid dendritic cell role in cutaneous malignancies.

    Saadeh, Dana; Kurban, Mazen; Abbas, Ossama

    2016-07-01

    Plasmacytoid dendritic cells (pDCs) correspond to a specialized dendritic cell population that exhibit plasma cell morphology, express CD4, CD123, HLA-DR, blood-derived dendritic cell antigen-2 (BDCA-2), and Toll-like receptor (TLR)7 and TLR9 within endosomal compartments. Through their production of type I interferons (IFNs) and other pro-inflammatory cytokines, pDCs provide anti-viral resistance and link the innate and adaptive immunity by controlling the function of myeloid DCs, lymphocytes, and natural killer (NK) cells. While lacking from normal skin, pDCs are usually recruited to the skin in several cutaneous pathologies where they appear to be involved in the pathogenesis of several infectious, inflammatory/autoimmune, and neoplastic entities. Among the latter group, pDCs have the potential to induce anti-tumour immunity; however, the complex interaction of pDCs with tumor cells and their micro-environment appears to contribute to immunologic tolerance. In this review, we aim at highlighting the role played by pDCs in cutaneous malignancies with special emphasis on the underlying mechanisms.

    Full Text Available We present a 60-year-old male patient who, three months after a holiday in Southern Greece, found a small ‘pimple’ on his back, which gradually got as big as a small walnut, the central part becoming ulcerated and scabby. Dermatological examination found an erythematous-to-livid nodular lesion on the right shoulder; it was 16 mm in diameter with central ulceration, covered with brownish crust which discharged pus-like secretion upon pressure. Microscope examination of Romanowsky-Giemsa stained lesion material detected amastigote forms of Leishmania tropica. The culture investigation and serological tests for leishmaniasis were negative. Dermoscopy of the lesion found the following features: erythema, hyperkeratosis, central ulceration covered with brownish crust, “yellow tears-like” structures and “white starburst-like” patterns, and various vascular structures (including dotted vessels, comma-shaped vessels, hairpin- and glomerular-like vessels. The patient was diagnosed with cutaneous leishmaniasis and underwent four cryotherapy sessions every other week with excellent therapeutic results - complete resolution of infiltrate with subsequent gentle hypopigmented scarring. In conclusion, dermoscopy is an easily accessible non-invasive method which can be useful for the diagnosis of cutaneous leishmaniasis. Cryotherapy is the treatment of choice for single skin lesions.

    Primary cutaneous lymphomas (PCLs) are a heterogeneous group of lymphoid tumors that originate primarily in the skin. Most PCLs (75%) are T-cell lymphomas and only 20% to 25% involve B cells. It is important to differentiate between cutaneous lymphomas and lymph node tumors given the differences in their molecular biology and clinical, histopathologic, and immunophenotypic features. Moreover, PCLs generally follow a more indolent course and require different treatments. Many treatment options are available for managing PLC's. The choice should be based primarily on the clinical stage of disease but must also take into consideration other factors, such as the patient's age and general health, the availability and accessibility of the treatment, and the cost-benefit ratio. It will be important to use a multidisciplinary approach, involving a team of expert dermatologists, hematologist-oncologists, and radiotherapists who are familiar with this rare disease. Recent years have seen the emergence of many new therapies, particularly for advanced stages of the disease and for patients whose tumors have proven refractory to treatment. The objective of this article is to review all the treatment options available to us. PMID:22575363

    Full Text Available Histoplasmosis, a systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum var capsulatum and Histoplasma capsulatum var duboisii is endemic to many parts of the world. The clinical manifestations range from acute or chronic pulmonary infection to a progressive disseminated disease. After initial exposure to the fungus, the infection is self-limited and restricted to the lungs in 99% of healthy individuals. The remaining 1%, however, progress to either disseminated or chronic disease involving the lungs, liver, spleen, lymph nodes, bone marrow or rarely, the skin and mucous membranes. Mucocutaneous histoplasmosis is frequently reported in patients with acquired immune deficiency syndrome (AIDS, but it is rare in immunocompetent hosts. A 60-year-old male presented with asymptomatic swelling of the hard palate and crusted papules and nodules over the extremities, face and trunk. Clinically, the diagnoses of cutaneous cryptococcosis versus histoplasmosis was considered in this patient. A chest X-ray revealed hilar lymphadenopathy. Enzyme-linked immunosorbent assay (ELISA for human immunodeficiency virus (HIV was nonreactive. Skin biopsy revealed multiple tiny intracellular round yeast forms with a halo in the mid-dermis. Culture of the skin biopsy in Sabouraud′s dextrose agar showed colonies of Histoplasma capsulatum. Despite an investigation including no evidence of underlying immunosuppression was found, he was started on IV amphotericin-B (0.5 mg/kg/day. However, the patient succumbed to his disease 2 days after presentation. We report a rare case of disseminated cutaneous histoplasmosis in an immunocompetent individual.

  18. Molecular Bases of Cutaneous and Uveal Melanomas

    Directory of Open Access Journals (Sweden)

    Sudeep Gaudi

    2011-01-01

    Full Text Available Intensive research in recent years has begun to unlock the mysteries surrounding the molecular pathogenesis of melanoma, the deadliest of skin cancers. The high-penetrance, low-frequency susceptibility gene CDKN2A produces tumor suppressor proteins that function in concert with p53 and retinoblastoma protein to thwart melanomagenesis. Aberrant CDKN2A gene products have been implicated in a great many cases of familial cutaneous melanoma. Sporadic cases, on the other hand, often involve constitutive signal transduction along the mitogen-activated protein kinase (MAPK pathway, with particular focus falling upon mutated RAS and RAF protooncogenes. The proliferative effects of the MAPK pathway may be complemented by the antiapoptotic signals of the PI3K/AKT pathway. After skin, melanoma most commonly affects the eye. Data for the constitutive activation of the MAPK pathway in uveal melanoma exists as well, however, not through mutations of RAS and RAF. Rather, evidence implicates the proto-oncogene GNAQ. In the following discussion, we review the major molecular pathways implicated in both familial and sporadic cutaneous melanomagenesis, the former accounting for approximately 10% of cases. Additionally, we discuss the molecular pathways for which preliminary evidence suggests a role in uveal melanomagenesis.

Therefore, the present retrospective study carried out to describe the demographic features of cutaneous leishmaniasis in Ramshir, Iran. Materials & Methods This descriptive study was performed on 136 cutaneous leishmaniasis patients whose data were recorded in the Ramshir health center during 2006-9. Demographic information of patients including age, sex, habitat and sites of lesions, month and years of incidence were recorded. The data were analyzed by SPSS 16 software. Findings Totally 79 patients (58.1% resided in urban areas and the born to 9 years (49.3% was recognized as the most infected age group. Hands (41.2% had the highest rates of cutaneous leishmaniasis lesions followed by face (36.0% and foot (22.8%. The maximum number of cutaneous leishmaniasis lesions was reported in March. Conclusion As cutaneous leishmaniasis in Ramshir seemed to be an endemic rural type, the appropriate preventing measures regarding to the rural cutaneous leishmaniasis should be considered to decrease incidence of the disease in the region.

    2016-10-01

    The diagnosis of malignancy in cutaneous and subcutaneous smooth muscle tumors is based on subtle criteria. Therefore, any ancillary technique useful in this differential diagnosis is always welcome. In this report, we study the immunoexpression of p53 in 19 malignant smooth muscle tumors of the skin (15 cutaneous leiomyosarcomas, 2 subcutaneous leiomyosarcomas, and 2 cutaneous metastases of leiomyosarcoma), as well as in 1 leiomyoma with cellular atypia, therefore complementing a previous study on p53 immunoexpression in leiomyomas of the skin. The p53 staining was positive in 12 (63.16%) of 19 leiomyosarcomas. Percentages of immunostaining in the positive cases varied from 2% to 95%. Ten (66.66%) of 15 cutaneous leiomyosarcomas were positive for p53, and in 4 of these cases, immunoexpression was demonstrated by more than 50% of the cells. Five (33.33%) cutaneous leiomyosarcomas did not show any expression of p53. Of the 2 subcutaneous leiomyosarcomas, one was negative for p53 and the other expressed the marker in 70% of the cells. The only atypical leiomyoma included in the study did not express p53. Of the 2 cutaneous metastases of leiomyosarcoma, one was negative and the other expressed p53 in 20% of the cells. The current study supports our previous conclusions that p53 immunoexpression in more than 1% of the cells in a cutaneous smooth muscle tumor is indicative of malignancy. However, we believe that additional studies on atypical leiomyoma are needed. PMID:27649950

  3. Adverse Cutaneous Reactions to Psychotropic Drugs: A Review

    2015-11-01

    Full Text Available Introduction: Psychotropic drugs are often implicated in cutaneous adverse drug reactions. While most of these reactions have a benign character, it is still important, however, to consider its role in the increasing stigma and treatment adherence. A small number of the cutaneous adverse drug reactions can develop into serious and potentially fatal conditions. Objectives: This article aims to review the most common cutaneous adverse drug reactions in patients taking psychotropic drugs. Methods: In this study, a search was carried out in the MEDLINE database for English language articles published , from 1999 to 2014, using as keywords: psychiatric, psychotropic, cutaneous, adverse reaction, antidepressive agents, antipsychotics, benzodiazepines, mood stabilizers, anticonvulsant, dementia. Information available from the Portuguese regulatory and supervising agency (Infarmed was also included.Results: 121 articles were found with reference to cutaneous adverse drug reactions associated with psychotropic drugs. The drugs most frequently reported as associated with such adverse effects were anticonvulsants used as mood stabilizers, followed by the antipsychotics . The antidementia drugs were rarely associated with serious cutaneous adverse reactions. Discussion and Conclusion: Cutaneous drug adverse reactions are common in psychiatric clinical practice and typically are minor in severity. The most severe reactions are most often associated with the use of mood stabilizing medications. Some of these side effects can be solved with reduction or drug discontinuation. More severe cases should be referred to a specialist in dermatology.

    Clinically, paragonimiasis is broadly classified into pulmonary, pleuropulmonary, and extrapulmonary forms. The common extrapulmonary forms are cerebral and cutaneous paragonimiasis. The cutaneous paragonimiasis is usually presented as a slowly migrating and painless subcutaneous nodule. The correct diagnosis is often difficult or delayed or remained undiagnosed until the nodule becomes enlarged and painful and the cause is investigated. We report here a case of cutaneous paragonimiasis in a male child who presented with mild respiratory symptoms. The diagnosis of paragonimiasis was based on a history of consumption of crabs, positive specific serological test, and blood eosinophilia. The swelling and respiratory symptoms subsided after a prescribed course of praziquantel therapy.

    Full Text Available Chrysosporium is a large genus of saprophytic fungi that is commonly found in the soil. Infection caused by this organism is rare in humans and typically occurs in immunocompromised patients. Primary cutaneous Chrysosporium infection is relatively rare and has been reported in a heart transplant patient. The prognosis is usually favorable, but very poor in the setting of persistent profound immunosuppression. We herein report a case of primary cutaneous Chrysosporium infection following ear piercing in an immunocompetent patient. It is important for clinicians to consider this condition in patients with slow-onset skin and soft tissue infection following cutaneous injury, even in an immunocompetent setting.

  8. Laser Doppler measurement of cutaneous blood flow

    International Nuclear Information System (INIS)

    Laser Doppler velocimetry is an instrument system which has only recently been applied to the evaluation and quantitation of perfusion in the micro-vascular bed. The instrument is based on the Doppler principle, but uses low power laser light rather than the more commonly used ultrasound, and has a sample volume of approximately 1 mm/sup 3/. As it is non-invasive, it can be used on any skin surface or exposed microvascular bed and provides a continuous semi-quantitative measure of microcirculatory perfusion, it has a number of advantages as compared to other cutaneous blood flow measurement techniques. Initial studies have shown that it is easily used, and it has demonstrated good correlation with both xenon radio-isotope clearance and microsphere deposition techniques. Areas of current evaluation and utilization are in most major areas of medicine and surgery and include plastic, vascular and orthopaedic surgery, dermatology, gastro-enterology, rheumatology, burns and anaesthesiology

    Full Text Available Background: Hypopigmented skin lesions is very common among people of all age groups. There are limited studies in India about evaluation of hypopigmented skin conditions. The aim of my study is to evaluate the different etiologies of cutaneous hypopigmentation. Aim: The present study was undertaken to find the relative incidence of the various disorders causing a hypopigmented lesion in a random sample of 200 cases and to study site, distribution and characteristics of the lesions. Methods: A random sample of 200 patients presenting with one or more hypopigmented lesions to the outpatient department of Dermatology, Venereology and Leprosy in KVG Medical College and Hospital, Sullia from December 2011 to January 2013 was studied. Detailed history including address and occupation with special reference to onset and duration, preceding skin conditions, exposure to chemicals, topical application and family history was taken. Various characteristics of the lesion like site, size, number, distribution, surface and sensation were studied. After this samples were taken for relevant investigations like complete hemogram, biopsy, slit skin smear, KOH mount and assessed for the causes of hypopigmented lesions. Results: In our study, most common cause with cutaneous hypopigmentation was pityriasis versicolor, seen in 52%, followed by post inflammatory hypopigmentation in 32%, pre vitiligo in 6.5%, Hansen’s disease, idiopathic guttate hypomelanosis, nevus anemicus each in 2%, Woronoff’s ring in 1.5% and miscellaneous conditions in 2% of the cases. Commonest age group affected was 21-30 years. Males (49% and females (51% were almost equally affected. Conclusion: The study concludes that various conditions comes under hypopigmentary disorders. More common in young adults. Most common scaly condition was pityriasis versicolor and non scaly condition was pre vitiligo. Proper counseling and ruling out Hansen’s disease is required to alleviate the patient

    Full Text Available Only a few published case of fibrous hamartoma of infancy (FHI have commented on the changes in the overlying skin. There are descriptions of individual cases with cutaneous hyperpigmentation, hypertrichosis and hyperhidrosis. It is interesting to describe our case because, to our knowledge, the altered pigmentation of the overlying skin, with hairs on the surface, and eccrine gland hyperplasia combined with abortive hair follicles has not been reported together in association with the FHI. We recommend that all the biopsies must be excisional including overlying skin, thus the epidermal and dermal adnexal changes can be assessed in the microscopic evaluation which could have relevant implications from clinical and embryological point of view.

    1999-01-01

    Cutaneous necrotizing vasculitis (CNV) is a complex multisystem disease generally involving the skin and mucous membranes, often accompanied by renal, gastrointestinal, pericardial, neurological, and articular signs and symptoms. CNV may be idiopatical or occur in association with a drug, infection, or underlying disease. CNV has been shown in patients with chronic infections (viral, bacterial, protozoa, helminthic), serum sickness, a variety of collagen vascular diseases (systemic lupus erythematous, Sjögren's syndrome, rheumatoid arthritis, Behçet's disease) hyperglobulinemic states, cryoglobulinemia, bowel bypass syndrome, ulcerative colitis, cystic fibrosis, primary biliary cirrhosis and HIV infection. Association with malignancies is not frequent. Lymphoproliferative disorders (Hodgkin's disease, mycosis fungoides, lymphosarcoma, adult T-cell leukemia, multiple mieloma) and solid tumors (lung cancer, colon carcinoma, renal, prostate, head and neck cancer and breast cancer) may be associated with CNV. Whenever possible, treatment is directed at the elimination of the cause. In other cases after adequate laboratory screening local and systemic therapy are recommended. PMID:10599332

    2003-02-01

    Cutaneous Leishmaniasis is a vector-borne protozoal infection of the skin. Several species of Leishmania cause this disease in the Old World. It is manifested as chronic nodular to ulcerative lesions of the skin, which last for many months and may be disfiguring. They eventually heal leaving a scar. Local care of the lesion and treatment of secondary bacterial infection are essential for healing. Antileishmania therapy is indicated in immunocompromised hosts, patients with progressive, multiple, or critically located lesions. Pentavalent antimony compounds remain the main therapeutic option for all species. They are given intravenously (i.v.), intramuscularly (i.m.), or intralesionally. Cryotherapy, and some systemic antifungal agents have been used successfully. Oral azoles are promising new treatments for lesions caused by L. Major. Several other alternatives and their evidence are also presented. PMID:12728282

    2002-01-01

    In attempt to increase cutaneous drug delivery, microemulsion vehicles have been more and more frequently employed over recent years. Microemulsion formulations have been shown to be superior for both transdermal and dermal delivery of particularly lipophilic compounds, but also hydrophilic...... compounds appear to benefit from application in microemulsions compared to conventional vehicles, like hydrogels, emulsions and liposomes. The favourable drug delivery properties of microemulsions appear to mainly be attributed to the excellent solubility properties. However, the vehicles may also act...... as penetration enhancers depending on the oil/surfactant constituents, which involves a risk of inducing local irritancy. The correlation between microemulsion structure/composition and drug delivery potential is not yet fully elucidated. However, a few studies have indicated that the internal structure...

    2014-04-01

    Full Text Available Breast cancer is the most frequently diagnosed type of cancer and the foremost reason of the death of women from cancer. Hormone receptor positive breast cancer is the most frequent type of breast cancer. Anastrosole is one of the aromatase inhibitors which is indicated for early stage of hormone receptor positive breast cancer of postmenopausal women. A 67-year-old woman was refered to Rheumatology Department from Medical Oncology Department for skin rashes which have started 3 months ago. In her medical history, she was diagnosed as infiltrative ductal carcinoma grade-2 in the right breast. She had a modified radical mastectomy operation for the right breast and subsequently, anastrosole was started as her hormone receptor was found positive in histopathological examination. The drug was stopped after 5 years by her oncologist however she went on using the drug on her own demand. Three months before her referral, non-itchy, painless reddish rash was started on legs and arms. After careful physical and laboratory examination and histopathologic alevaluation, she was diagnosed as middle-vessel necrotising vasculitis. Anastrosole was stopped. Steroid and azathyoprine were started. On the fifth month of therapy, all skin lesions were resolved with postinflammatory hyperpigmentation. No additional problem was met. This case report is suggesting that, anastrosole which is a frequently preferred agent in recentyears, could also cause leucocytoclastic vasculits. Very rare cases with cutanous vasculitis were previously presented. This case report suggests that, during the management of patients under anastrosole therapy, cutanous vasculitis should be monitored carefully. [Cukurova Med J 2014; 39(2.000: 369-372

    In 1985, Carney et al reported a complex of myxomas, spotty pigmentation, and endocrine overactivity and subsequently demonstrated dominant inheritance of the condition. The criteria for diagnosis of the complex is the presence of two or more of the following conditions: (1) cardiac myxoma, (2) cutaneous myxoma, (3) mammary myxoma, (4) spotty mucocutaneous pigmentation, (5) primary pigmented nodular adrenocortical disease (Cushing's syndrome), (6) testicular tumors (sexual precocity), (7) pituitary adenoma secreting growth hormone (acromegaly or gigantism). We encountered a family with an affected mother and daughter. Case 1 was a 43-year-old woman with multiple cutaneous myxomas, mammary myxomas and spotty mucocutaneous pigmentation. Case 2, the 19-year-old daughter of case 1 had multiple cutaneous myxomas and spotty cutaneous pigmentation. These two cases both met the criteria for the diagnosis of the complex. Our report is believed to be the first report on the complex in Japan. PMID:2266598

    2009-12-01

    Tungiasis (sand flea disease) and cutaneous larva migrans (creeping eruption) are parasitic skin diseases in which the infectious agents only temporarily invade human skin. The parasites die in situ and eventually are eliminated by tissue repair mechanisms. Both diseases are zoonoses. Humans only accidentally become a host for animal hookworm larvae (resulting in cutaneous larva migrans), but get infected with Tunga penetrans as frequent as domestic animals. In travelers to tropical and subtropical regions tungiasis and cutaneous larva migrans are the most common imported skin diseases. The diagnosis is made clinically. In tungiasis the clinical manifestations depend on the stage of the disease. Intense local inflammation and bacterial superinfection are common. Cutaneous larva migrans is treated orally with ivermectin or albendazole. A repellent based on coconut oil effectively prevents penetration of sand fleas.

  18. Topical menthol increases cutaneous blood flow.

    Science.gov (United States)

    Craighead, Daniel H; Alexander, Lacy M

    2016-09-01

    Menthol, the active ingredient in several topically applied analgesics, activates transient receptor potential melastatin 8 (TRPM8) receptors on sensory nerves and on the vasculature inducing a cooling sensation on the skin. Ilex paraguariensis is also a common ingredient in topical analgesics that has potential vasoactive properties and may alter the mechanisms of action of menthol. We sought to characterize the microvascular effects of topical menthol and ilex application and to determine the mechanism(s) through which these compounds may independently and combined alter cutaneous blood flow. We hypothesized that menthol would induce vasoconstriction and that ilex would not alter skin blood flow (SkBF). Three separate protocols were conducted to examine menthol and ilex-mediated changes in SkBF. In protocol 1, placebo, 4% menthol, 0.7% ilex, and combination menthol+ilex gels were applied separately to the skin and red cell flux was continuously measured utilizing laser speckle contrast imaging (LSCI). In protocol 2, seven concentrations of menthol gel (0.04%, 0.4%, 1%, 2%, 4%, 7%, 8%) were applied to the skin to model the dose-response curve. In protocol 3, placebo, menthol, ilex, and menthol+ilex gels were applied to skin under local thermal control (34°C) both with and without sensory nerve blockage (topical lidocaine 4%). Post-occlusive reactive hyperemia (PORH) and local heating (42°C) protocols were conducted to determine the relative contribution of endothelium derived hyperpolarizing factors (EDHFs)/sensory nerves and nitric oxide (NO), respectively. Red cell flux was normalized to mean arterial pressure expressed as cutaneous vascular conductance (CVC: flux·mmHg(-1)) in all protocols. Topical menthol application increased SkBF compared to placebo (3.41±0.33 vs 1.1±0.19CVC: peffect, p<0.05) with an ED50 of 1.0%. Similarly, SkBF was increased after menthol application during PORH (3.62±0.29 vs. 2.50±0.21flux·mmHg(-1); p<0.001), but not local heating

    Cutaneous manifestations of parasitic infections often result in discomfort, debilitation, and even stigmatization. Data on cutaneous manifestations of parasitic infections, however, are limited. This article provides updates on the cutaneous manifestations of parasitic infections which are known to occur in Western Pacific and Southeast Asian regions, such as scabies, pediculosis, cutaneous larva migrans, larva currens, cutaneous schistosomiasis, cutaneous enterobiasis, cutaneous cysticercosis, acute dermatolymphangioadenitis (lymphatic filariasis), and cutaneous amoebiasis. The lack of epidemiological data on these conditions suggests the need for improvements in recording and reporting of cases. Utilization of advance diagnostic modalities and capacity building of health workers are important for proper case management. Cutaneous manifestations of parasitic infections are a topic rarely studied and thus represent an opportunity for further research. PMID:27447892

    2011-07-30

    Efficient topical drug administration for the treatment of superficial fungal infections would deliver the therapeutic agent to the target compartment and reduce the risk of systemic side effects. However, the physicochemical properties of the commonly used azole antifungals make their formulation a considerable challenge. The objective of the present investigation was to develop aqueous micelle solutions of clotrimazole (CLZ), econazole nitrate (ECZ) and fluconazole (FLZ) using novel amphiphilic methoxy-poly(ethylene glycol)-hexyl substituted polylactide (MPEG-hexPLA) block copolymers. The CLZ, ECZ and FLZ formulations were characterized with respect to drug loading and micelle size. The optimal drug formulation was selected for skin transport studies that were performed using full thickness porcine and human skin. Penetration pathways and micellar distribution in the skin were visualized using fluorescein loaded micelles and confocal laser scanning microscopy. The hydrodynamic diameters of the azole loaded micelles were between 70 and 165nm and the corresponding number weighted diameters (d(n)) were 30 to 40nm. Somewhat surprisingly, the lowest loading efficiency (13-fold higher than that from Pevaryl® cream (22.8±3.8 and 1.7±0.6μg/cm(2), respectively). A significant enhancement was also observed with human skin; the amounts of ECZ deposited were 11.3±1.6 and 1.5±0.4μg/cm(2), respectively (i.e., a 7.5-fold improvement in delivery). Confocal laser scanning microscopy images supported the hypothesis that the higher delivery observed in porcine skin was due to a larger contribution of the follicular penetration pathway. In conclusion, the significant increase in ECZ skin deposition achieved using the MPEG-dihexPLA micelles demonstrates their ability to improve cutaneous drug bioavailability; this may translate into improved clinical efficacy in vivo. Moreover, these micelle systems may also enable targeting of the hair follicle and this will be investigated

    There is an increasing interest in the etiology of cutaneous malignant melanoma (CMM). Once considered a rare tumour, CMM is now the fourth commonest cancer in Australia and New Zeland, the tenth in the Usa, Canada and Scandinavia and the eighteenth in Great Britain. The growing scientific concern on the urgent need to highlight the cause/s of CMM is well documented by the large number of well-designed and well-conducted epidemiological studies reported in the last two decades. Such studies facilitated testing of many etiological hypotheses derived from earlier descriptive investigations and contributed to significant progress in understanding the etiology of such disease. The quantification of the extent to which the increases in CMM incidence and mortality rates are related to new lifestyles and to new patterns of exposure to potential carcinogenetic agents is essential in order to establish an appropriate preventive strategy. In population of mainly European origin a substantial proportion of the increased incidence of CMM is attributable to steady change from predominantly occupational to predominantly recreational exposure to solar radiation. Therefore the present review puts particular emphasis on exposure to sunlight as well as to artificial ultraviolet light, as modifiable causes of CMM. Incidence and mortality data and other potential risk factors for the development of CMM will also be briefly reviewed.

  2. Cutaneous cylindroma: it's all about MYB.

    2016-08-01

    Cutaneous cylindroma is a rare benign tumour that occasionally turns into malignant cylindrocarcinoma. The cancer can be sporadic or emerge in the context of Brooke-Spiegler syndrome (BSS), an inheritable condition characterized by mutation of the gene CYLD, encoding a tumour suppressor protein that controls the activity of the transcription factor NF-kB. Sporadic cylindromas present histological features shared with adenoid cystic carcinoma (ACC), a head and neck cancer originating from salivary or other exocrine glands. Like ACCs, sporadic cylindromas express, although at lower frequency, the aberrant fusion transcript MYB-NFIB. In a paper recently published in the Journal of Pathology, the research teams led by Neil Rajan and Goran Stenman demonstrate that CYLD-defective cyclindromas in BSS patients are negative for the MYB-NFIB fusion. Only the wild-type MYB oncoprotein is activated in the majority of these tumours. RNA interference studies in cells derived from BSS patients indicate that ablating MYB expression results in a striking reduction of cylindroma cell proliferation, suggesting that MYB plays a pivotal role in the biology of this cancer. The take-home message of the study is that activation of MYB, in its wild-type form or fusion derivatives, is a common feature of spontaneous and hereditary cylindromas, constituting a potentially actionable therapeutic target.

    2012-08-01

    The mammalian skin has developed sensory structures (mechanoreceptors) that are responsible for different modalities of mechanosensitivity like touch, vibration, and pressure sensation. These specialized sensory organs are anatomically and functionally connected to a special subset of sensory neurons called mechanosensory neurons, which electrophysiologically correspond with Aβ fibers. Although mechanosensory neurons and cutaneous mechanoreceptors are rather well known, the biology of the sense of touch still remains poorly understood. Basically, the process of mechanosensitivity requires the conversion of a mechanical stimulus into an electrical signal through the activation of ion channels that gate in response to mechanical stimuli. These ion channels belong primarily to the family of the degenerin/epithelium sodium channels, especially the subfamily acid-sensing ion channels, and to the family of transient receptor potential channels. This review compiles the current knowledge on the occurrence of putative mechanoproteins in mechanosensory neurons and mechanoreceptors, as well as the involvement of these proteins on the biology of touch. Furthermore, we include a section about what the knock-out mice for mechanoproteins are teaching us. Finally, the possibilities for mechanotransduction in mechanoreceptors, and the common involvement of the ion channels, extracellular membrane, and cytoskeleton, are revisited.

    Full Text Available Anthrax is a zoonotic disease of grass-eating animals such as cattle, sheep, goats, and transmitted to humans by infected animals. Declining with each passing day in our country is still an endemic disease. Cutaneous anthrax is 95% of the cases. In this study, 5 patients from the same family who admitted to the emergency department with a complaint of a painless and black colored wound on their hands are discussed and skin anthrax diagnosed. Four male, 1 female family members who cut a cattle a week before were evaluated in the emergency department with a wound on their hands%u2019 backside. One of the patients hospitalized with the diagnosis of anthrax, and accepted to the infectious diseases clinic, and 4 were discharged by outpatient treatment arranged. In controls after two weeks, the patients were fully recovered without complications. Early diagnosis and treatment can show 100% improvement in skin anthrax, suspicious skin lesion and recently animal contact history should be considered in patients.

  5. Myeloid Cells in Cutaneous Wound Repair.

    Cash, Jenna L; Martin, Paul

    2016-06-01

    Cutaneous wound repair is a complex, dynamic process with the goal of rapidly sealing any breach in the skin's protective barrier. Myeloid cells compose a significant proportion of the inflammatory cells recruited to a wound site and play important roles in decontaminating the injured tissue of any invading microorganisms. Subsequently, myeloid cells are able to influence many aspects of the healing response, in part through their capacity to release a large array of signaling molecules that allow them to communicate with and regulate the behavior of other wound cells and in turn, be themselves exquisitely regulated by the wound microenvironment. Macrophages, for example, appear to play important, temporally changing roles in the initiation of scarring and subsequently in matrix remodeling to resolve fibrosis. In this way, myeloid cells seem to play both positive (e.g., pathogen killing and matrix remodeling) and negative (e.g., scarring) roles in wound repair. Further research is of course needed to elucidate the precise temporal and spatial myeloid cell phenotypes and behaviors and ultimately to design effective strategies to optimize the beneficial functions of these cells while minimizing their detrimental contributions to improve wound healing in the clinic.

    Full Text Available Background: leishmaniasis infection might manifest as sarcoidosis; on the other hand, some evidences propose an association between sarcoidosis and leishmaniasis. Most of the times, it is impossible to discriminate idiopathic sarcoidosis from leishmaniasis by conventional histopathologic exam. Aim: We performed a cross-sectional study to examine the association of sarcoidosis with leishmaniasis in histopathologically diagnosed sarcoidal granuloma biopsy samples by polymerase chain reaction (PCR. Materials and Methods: We examined paraffin-embedded skin biopsy samples obtained from patients with clinical and histopathological diagnosis as naked sarcoidal granuloma, referred to Skin Research Center of Shaheed Beheshti Medical University from January 2001 to March 2010, in order to isolate Leishmania parasite. The samples were reassessed by an independent dermatopathologist. DNA extracted from all specimens was analyzed by the commercially available PCR kits (DNPTM Kit, CinnaGen, Tehran, Iran to detect endemic Leishmania species, namely leishmania major (L. major. Results: L. major was positive in PCR of Eight out of twenty-five examined samples. Conclusion: Cutaneous leishmaniasis may be misinterpreted as sarcoidosis; in endemic areas, when conventional methods fail to detect Leishmania parasite, PCR should be utilized in any granulomatous skin disease compatible with sarcoidosis, regardless of the clinical presentation or histopathological interpretation.

  7. Worldwide Increasing Incidences of Cutaneous Malignant Melanoma

    Directory of Open Access Journals (Sweden)

    Dianne E. Godar

    2011-01-01

    Full Text Available The incidence of cutaneous malignant melanoma (CMM has been increasing at a steady rate in fair-skinned populations around the world for decades. Scientists are not certain why CMM has been steadily increasing, but strong, intermittent UVB (290–320 nm exposures, especially sunburn episodes, probably initiate, CMM, while UVA (321–400 nm passing through glass windows in offices and cars probably promotes it. The CMM incidence may be increasing at an exponential rate around the world, but it definitely decreases with increasing latitude up to ~50°N where it reverses and increases with the increasing latitude. The inversion in the incidence of CMM may occur because there is more UVA relative to UVB for most of the year at higher latitudes. If windows, allowing UVA to enter our indoor-working environment and cars, are at least partly responsible for the increasing incidence of CMM, then UV filters can be applied to reduce the rate of increase worldwide.

  9. Control of the Cutaneous Circulation by the Central Nervous System.

    Science.gov (United States)

    Blessing, William; McAllen, Robin; McKinley, Michael

    2016-01-01

    The central nervous system (CNS), via its control of sympathetic outflow, regulates blood flow to the acral cutaneous beds (containing arteriovenous anastomoses) as part of the homeostatic thermoregulatory process, as part of the febrile response, and as part of cognitive-emotional processes associated with purposeful interactions with the external environment, including those initiated by salient or threatening events (we go pale with fright). Inputs to the CNS for the thermoregulatory process include cutaneous sensory neurons, and neurons in the preoptic area sensitive to the temperature of the blood in the internal carotid artery. Inputs for cognitive-emotional control from the exteroceptive sense organs (touch, vision, sound, smell, etc.) are integrated in forebrain centers including the amygdala. Psychoactive drugs have major effects on the acral cutaneous circulation. Interoceptors, chemoreceptors more than baroreceptors, also influence cutaneous sympathetic outflow. A major advance has been the discovery of a lower brainstem control center in the rostral medullary raphé, regulating outflow to both brown adipose tissue (BAT) and to the acral cutaneous beds. Neurons in the medullary raphé, via their descending axonal projections, increase the discharge of spinal sympathetic preganglionic neurons controlling the cutaneous vasculature, utilizing glutamate, and serotonin as neurotransmitters. Present evidence suggests that both thermoregulatory and cognitive-emotional control of the cutaneous beds from preoptic, hypothalamic, and forebrain centers is channeled via the medullary raphé. Future studies will no doubt further unravel the details of neurotransmitter pathways connecting these rostral control centers with the medullary raphé, and those operative within the raphé itself. © 2016 American Physiological Society.

  10. Agraphesthesia. A disorder of directional cutaneous kinesthesia or a disorientation in cutaneous space.

    Bender, M B; Stacy, C; Cohen, J

    1982-03-01

    Tests for graphesthesia and for directional cutaneous kinesthesia (DCK) were performed on a large series of neurological patients and normal subjects, in addition to the standard tests for discriminative sensation. Defects in graphesthesia and DCK were found with lesions at all levels of the nervous system. Graphesthesia was more often and more severely affected than DCK. These functions when impaired were always associated with other sensory defects (directional joint kinesthesia, two-point discrimination, etc.) in different combinations. It appears DCK is probably the basis for graphesthesia. Recent experimental studies have provided an anatomic and physiologic basis for DCK and for graphesthesia. These studies have also discredited wide-held beliefs on the transmission of discriminative sensation through the spinal cord. In this light, the history of ideas about sensation and its mediation is reviewed, and it is concluded that DCK alone deserves to be called a "posterior column function". Graphesthesia and DCK are discussed as kinesthetic functions implying orientation in cutaneous sensory space. These are compared to stereognosis and braille reading, which are complex derived functions depending also on motion, but directed towards recognition in external haptic space. Graphesthesia and DCK should both be considered as distinct forms of somatic sensibility which are valuable adjuncts to the clinical sensory examination.

    Chromoblastomycosis is a rare chronic fungal infection of skin and subcutaneous tissue. It is primarily a disease of tropical and subtropical regions and affects mainly the agricultural workers following trauma with vegetable matter. Cutaneous Chromoblastomycosis may clinically mimic cutaneous tuberculosis as both the condition usually presents with hyper pigmented verrucous lesion of skin. Here in we report a case of chronic cutaneous Chromoblastomycosis in a middle aged woman from north eastern part of India, who was initially misdiagnosed as Tuberculosis verrucosa cutis. In histopathology characteristic brown colored spores of the fungus (also known as copper pennies) were seen within dermal abscess. The organism isolated from culture of the biopsy material was Fonsecaea pedrosoi thus confirming our diagnosis of cutaneous chromoblastomycosis. The patient responded well to oral Itraconazole. The dermatologists and pathologists should be aware of this condition especially when dealing with verrucous lesion of the skin. The pathologists should search for fungal spores in cutaneous lesion with pseudoepitheliomatous hyperplasia and dermal abscess. PMID:24272932

  14. Photodynamic therapy for multi-resistant cutaneous Langerhans cell histiocytosis

    2010-06-01

    Full Text Available Langerhans cell histiocytosis is a rare group of proliferative disorders. Beside cutaneous involvement, other internal organs can be affected. The treatment of cutaneous lesions is difficult and relies on topical corticosteroids, carmustine, nitrogen mustard, and photochemotherapy. Systemic steroids and vinblastine are used for recalcitrant skin lesions. However, some cases fail to respond. An 18-month old boy presented a CD1a+, S100a+ Langerhans cell histocytosis with cutaneous and severe scalp involvement. Topical corticosteroids and nitrogen mustard failed to improve the skin lesions. Systemic corticosteroids and vinblastine improved the truncal involvement but had no effect on the scalp lesions. Methyl-aminolevulinate (MAL based photodynamic therapy (PDT resulted in a significant regression of the scalp lesions. Control histology revealed an almost complete clearance of the tumor infiltrate. Clinical follow-up after six months showed no recurrence. Although spontaneous regression of cutaneous Langerhans cell histiocytosis is observed, the rapid effect of photodynamic therapy after several failures of other treatment suggests that photodynamic therapy was successful. As far as we know this is the first report of photodynamic therapy for refractory skin lesions. Larger series are needed to determine whether photodynamic therapy deserves a place in the treatment of multiresistant cutaneous Langerhans cell histiocytosis.

  15. The Role of Iron in the Skin & Cutaneous Wound Healing

    Directory of Open Access Journals (Sweden)

    Josephine Anne Wright

    2014-07-01

    Full Text Available In this review article we discuss current knowledge about iron in the skin and the cutaneous wound healing process. Iron plays a key role in both oxidative stress and photo-induced skin damage. The main causes of oxidative stress in the skin include reactive oxygen species (ROS generated in the skin by ultraviolet (UVA 320-400 nm portion of the ultraviolet spectrum and biologically available iron. We also discuss the relationships between iron deficiency, anaemia and cutaneous wound healing. Studies looking at this fall into two distinct groups. Early studies investigated the effect of anaemia on wound healing using a variety of experimental methodology to establish anaemia or iron deficiency and focused on wound-strength rather than effect on macroscopic healing or re-epithelialisation. More recent animal studies have investigated novel treatments aimed at correcting the effects of systemic iron deficiency and localised iron overload. Iron overload is associated with local cutaneous iron deposition, which has numerous deleterious effects in chronic venous disease and hereditary haemochromatosis. Iron plays a key role in chronic ulceration and conditions such as Rheumatoid Arthritis (RA and Lupus Erythematosus are associated with both anaemia of chronic disease and dysregulation of local cutaneous iron haemostasis. Iron is a potential therapeutic target in the skin by application of topical iron chelators and novel pharmacological agents, and in delayed cutaneous wound healing by treatment of iron deficiency or underlying systemic inflammation.

    Introduction. Angiosarcoma is a rare cancer of the inner lining of blood vessels and can arise anywhere in the body, most commonly presenting as cutaneous disease in elderly patient, involving head and neck (H&N), especially the scalp. Pegylated liposomal doxorubicin (PLD) is one of the available treatments in patients with advanced or metastatic disease. Common toxicities are myelosuppression, palmar-plantar erythrodysesthesia, nausea, and stomatitis. Regarding PLD-related pulmonary fibrosis in an uncommon toxicity, there are few cases reported in literature. None of these occurred in angiosarcoma. Methods. This is a case report describing an elderly patient treated with PLD for advanced H&N cutaneous angiosarcoma who developed G5 pulmonary toxicity after the second PLD administration. Results. According to our data and patient clinical outcome, we believe that she passed away from fatal PLD-induced pulmonary fibrosis. This is the first case of fatal interstitial pneumonitis in a 77-year-old woman treated with PLD for angiosarcoma. The case has been reported for its rarity. Conclusions. Pathophysiology of this phenomenon is still unclear and more studies are necessary to understand the true incidence of pulmonary toxicities in patients in treatments with PLD and its mechanism.

    2016-01-01

    Acaricidal (tick) and insecticidal (flea) efficacy of systemically and cutaneously distributed ectoparasiticide products for dogs are compared based on permethrin and fluralaner as representative molecules. Results of efficacy studies against fleas and ticks are reviewed that show generally good to excellent results. Both externally and systemically distributed treatments have benefits and weaknesses in potentially preventing pathogen transmission by these arthropod vectors.Four general properties are considered related to the goal of providing optimal reduction in the risk of vector-borne pathogen transmission. These are: 1. Owner adherence to the recommended treatment protocol; 2. Rapid onset of activity following administration; 3. Uniform efficacy over all areas of the treated dog at risk for parasite attachment; 4. Maintenance of high efficacy throughout the retreatment interval. In considering these four factors, a systemically distributed acaricide can offer an option that is at least as effective as a cutaneously administered acaricide with regard to the overall goal of reducing the risk of vector-borne pathogen transmission.

    Full Text Available Background and Aim: Cutaneous tuberculosis (CTB is still difficult to diagnose due to its varied clinical presentation and limitations of diagnostic methods. The aim of this study was to evaluate the results of diagnostic laboratory tests available for CTB. Materials and Methods: Twenty-six skin biopsy specimens belonging to clinically suspected cases of CTB were studied retrospectively. The specimens were divided into two portions, one part processed for histopathological evaluation and the other was used for microscopy and inoculation for the isolation of mycobacteria. Polymerase chain reaction (PCR technique was applied to 14 of 26 specimens to detect Mycobacterium tuberculosis complex (MTBC DNA. Results: Of the 26 biopsy specimens, 11 were confirmed as CTB by identification of MTBC in culture and/or histopathologic affirmation. Of these, four were lupus vulgaris, four were TB verrucosa cutis, one was scrofuloderma, one was primary inoculation TB, and one was periorifical CTB. Culture for mycobacteria was positive for five (45.45% specimens, while histopathologic affirmation was obtained in ten (90.90% specimens. Acid-fast Bacilli were not demonstrated in any of the specimens on microscopic examination. The PCR was found to be applied to six of the 11 specimens diagnosed as CTB and was positive in two specimens (33.3%, which were positive for growth in culture and histopathological correlation. Conclusion: The recovery rate of MTBC from biopsy specimens was found to be satisfactory for CTB with histopathological correlation, but the combination of culture with a rapid method, PCR, may improve the diagnostic rate.

    Prolonged healing and scar formation are two major challenges in the treatment of soft tissue trauma. Adipose mesenchymal stem cells (ASCs) play an important role in tissue regeneration, and recent studies have suggested that exosomes secreted by stem cells may contribute to paracrine signaling. In this study, we investigated the roles of ASCs-derived exosomes (ASCs-Exos) in cutaneous wound healing. We found that ASCs-Exos could be taken up and internalized by fibroblasts to stimulate cell migration, proliferation and collagen synthesis in a dose-dependent manner, with increased genes expression of N-cadherin, cyclin-1, PCNA and collagen I, III. In vivo tracing experiments demonstrated that ASCs-Exos can be recruited to soft tissue wound area in a mouse skin incision model and significantly accelerated cutaneous wound healing. Histological analysis showed increased collagen I and III production by systemic administration of exosomes in the early stage of wound healing, while in the late stage, exosomes might inhibit collagen expression to reduce scar formation. Collectively, our findings indicate that ASCs-Exos can facilitate cutaneous wound healing via optimizing the characteristics of fibroblasts. Our results provide a new perspective and therapeutic strategy for the use of ASCs-Exos in soft tissue repair. PMID:27615560

    Mycobacterium marinum is an atypical and non-tuberculosis mycobacterium that mainly leads to cutaneous infections. Infections occur through inoculation of the organism through injury to the skin in the presence of contaminated water or fish. The patient often presents with unspecific symptoms and the evolution, in the absence of adequate treatment, is characterized by an expansion of the cutaneous lesion and a spread to deep structures. Infections of tendon sheaths and joints are described, rarely osteomyelitis. Sure diagnosis is hard to obtain and is established from the medical history and microbiological examination. There are no specific therapeutic guidelines. Double or triple antibiotherapy is often effective and should be continued several months after complete resolution of clinical signs. Surgical debridement is required in cases of invasive or resistant infections. We report the case of a young immunocompetent fishmonger with a rare osteocutaneous M. marinum infection of the elbow. Treatment included large surgical excision of infected skin and bone areas and a triple antibiotics administration. Reconstruction have been ensured by a radial collateral artery perforator-based propeller flap, satisfying appropriates functional and cosmetical concerns of this anatomical region. Surgery and appropriate antibiotics treatment were effective and allowed healing of an invasive cutaneous and bone M. marinum infection.

Reconstruction have been ensured by a radial collateral artery perforator-based propeller flap, satisfying appropriates functional and cosmetical concerns of this anatomical region. Surgery and appropriate antibiotics treatment were effective and allowed healing of an invasive cutaneous and bone M. marinum infection. PMID:26748858

    Full Text Available Cutaneous B cell lymphomas can arise primarily from the skin or may occur due to secondary spread from nodal lymphomas. Primary lymphomas are confined to the skin without systemic spread and they differ from secondary lymphomas in their clinical behavior, treatment and prognosis. Cutaneous lymphomas being relatively rare, lack of precise definition and understanding of their clinical behavior diseases leads to pitfalls in the diagnosis. We report two cases of cutaneous B cell lymphomas who presented with fever of unknown origin initially and later found to have skin lesions. Hence, skin can be a potential diagnostic clue in the evaluation of patients with fever of unknown origin. The distinctions between the primary and the secondary lymphomas become important in choosing the treatment and assessing the prognosis.

    Primary cutaneous plasmacytoma is a rare type of cutaneous B-cell lymphoma, characterized by clonal proliferation of plasma cells, that primarily develops in the skin. Five cases have been described to date in which a local triggering stimulus may be involved in development of this skin tumour. We describe the case of a primary cutaneous plasmacytoma localized to the lower lip. This site had been affected for 15 years with recurrent herpes simplex virus-1 infection. Neoplastic plasma cells were found to be bcl-2-positive. We hypothesize that chronic stimulation of keratinocytes by herpes simplex virus-1, possibly through toll-like receptors, may have favoured the release of cytokines (e.g. interleukin-6) able to induce plasma cell proliferation, transformation and survival.

    p53 gene mutation appears to play an important role in the development of systemic lymphoma, and may be associated with tumour progression. Its role in cutaneous lymphoma is currently unknown. We examined p53 expression in 55 biopsies of cutaneous lymphoma, including patch-, plaque- and tumour-stage mycosis fungoides (MF), T- and B-cell lymphoma and lymphomatoid papulosis. Strong, homogeneous p53 expression, thought to correlate most closely with p53 gene mutation, was seen in only three cases; in a plaque and tumour from a patient with tumour-stage MF, in plaque-stage MF in a patient without tumours, and in one case of CD30+ large-cell anaplastic lymphoma. These data suggest that p53 gene mutation is not a critical step in the development of the majority of primary cutaneous lymphomas.

    The term isotopic response refers to the appearance of a new skin disease at the site of another unrelated and already healed skin disorder. Often, the first disease is herpes zoster (HZ). Several cutaneous reactions have been described in a dermatome recently affected by HZ. We present the case of a 33-year-old man who developed whitish papules with a zosteriform distribution on HZ scars. Histopathologic study with hematoxylin and eosin and Alcian blue (pH 2.5) staining demonstrated abundant deposits of mucin interstitially arranged between collagen bundles of the papillary dermis. Cutaneous dermal mucinosis as a postherpetic isotopic response is rare, but it should be added to the list of cutaneous reactions arising in HZ scars. PMID:27529717

    Full Text Available Mastocytosis is a disorder characterized by the clonal proliferation of mast cells and their accumulation in skin, bone marrow, liver, and spleen. Cutaneous mastocytosis presents in children in over 90% of the cases and any cutaneous manifestation in an adult is the earliest sign of the systemic disease. A 45-year-old patient presented with itchy dark lesions over the body since childhood and Darier's sign was positive. Skin biopsy showed features of mastocytosis and immunohistochemistry was positive for CD34. Since the patient was refractory to treatment with antihistamines and psoralen-ultraviolet A therapy, injections of interferon alpha were given – 3 million IU twice weekly subcutaneously as they have been proven to improve constitutional symptoms. Very few reports of successful treatment of cutaneous mastocytosis using interferon alpha have been published.

    Full Text Available Context: Cutaneous metastasis from head and neck cancer is uncommon and it is seen from laryngeal cancer. Cutaneous metastasis from the base of tongue is relatively rare. Case Report: A 55-year-old male, who was a treated case of squamous carcinoma of the base of tongue presented with metastatic nodule on the skin of face and thigh. But, there was complete resolution of the tumor at the primary site. In the present case, clinically obvious cutaneous nodules with metastasis appeared soon after the completion of treatment with concurrent chemo-radiotherapy. The metastasis to the skin of face clinically appeared like an inflammatory lesion. Fine needle aspiration cytology confirmed the diagnosis of metastasis to skin at both the sites. Conclusion: Our case has highlighted that there could be associated occult skin metastasis at the time of diagnosis in squamous carcinoma of the base of tongue.

    2012-10-01

    Mucoepidermoid carcinoma (MEC) of the skin is an extremely rare neoplasm but is common in the major and minor salivary glands accounting of approximately 30% of all malignant tumors arising from these glands. Cutaneous involvement should be carefully assessed to exclude the possibility of metastases from distant sites. We report an 81 year-old man presenting a primary cutaneous mucoepidermoid carcinoma infiltrating his left parotid gland. Excision of the affected skin and a total parotidectomy with supraomohyoid neck dissection (level I-III) was performed followed by radiotherapy. No relapse after 2 years follow up has been observed. Since the primary cutaneous mucoepidermoid carcinoma is an aggressive neoplasm that frequently develops metastases it is important to distinguish it from primary MEC originating from the salivary glands for better management and suitable therapeutic decisions.

    Koebner isomorphic response describes the phenomenon of histopathologically identical skin lesions of a preceding cutaneous disease appearing in sites of trauma. Wolf isotopic response describes the phenomenon of a new skin disease appearing in the site of an unrelated cutaneous disease. Neither of the phenomena has been reported in relation to systemic lupus erythematosus. This report describes a 17-year-old girl with systemic lupus erythematosus exhibiting particularly severe cutaneous involvement confined primarily to sun-exposed areas presenting with a dermatomal band of atrophic, scaling, erythematous papules, and plaques on her left shoulder extending down her left arm after herpes zoster eruption. The histopathologil result showed lupus erythematosus. This phenomenon is best considered as a Koebner isomorphic response, although Wolf isotopic response has some clinical relevance as well. Koebner isomorphic and Wolf isotopic responses are discussed as related to this case. PMID:22639953

    2007-12-01

    Full Text Available Abstract Introduction A cutaneous horn is a conical projection of hyperkeratotic epidermis. Though grossly resembling an animal horn, it lacks a bony core. These lesions have been well described in Caucasian patients, as well as in a number of Arabic and Asian patients. Case presentation A young female presented with a large 'horn' of five-year duration, arising from a burn scar. Excision and scalp reconstruction were performed. Histology was reported as verrucoid epidermal hyperplasia with cutaneous horn. Conclusion This may be the first documentation of this lesion in a black African. Although likely rare, it should be considered in the differential diagnosis of dermatologic lesions. Up to 40% of cutaneous horns occur as part of a premalignant or malignant lesion, and surgical extirpation with histological examination is thus more important than the curiosity surrounding these lesions.

    Breast cancer is the most common cause of cutaneous metastases from internal malignancies. Generally, the neoplastic cells are located in the dermis or hypodermis, while a finding of transepidermal elimination on cutaneous metastases is exceptional. In this report we present a patient with perforating cutaneous metastases from breast cancer with mucin 1 expression. Cutaneous, bone, lung, and hepatic lesions were detected two years after the diagnosis of the primary tumor.

    Abstract The incidence of cutaneous and subcutaneous metastases from atypical laryngeal carcinoids is approximately 20%. However, the pathogenesis and natural history of, and prognostic factors for, the condition remain poorly understood. We reported a 54-year-old female presented with cutaneous and subcutaneous metastases from atypical laryngeal carcinoid. Laryngoscopy revealed a 0.5 × 1.5-cm reddish mass on the laryngeal surface of the epiglottis. Under general anesthesia, a biopsy sample was obtained via suspension laryngoscopy. Routine pathology revealed atypical laryngeal carcinoid. Immunohistochemical staining of the sections of primary tumor was positive for cytokeratin, chromogranin A, synaptophysin, hypoxia-inducible factor-1α, P53, and CD56. GLUT-1, p-Akt, and PI3K were negative. The Ki-67 index was 15%. Supraglottic laryngectomy and selective right-neck dissection were performed. After 6 months, the patient complained of pain in the right wall of the chest; multiple cutaneous and subcutaneous nodules were evident at that site and in the abdomen. An abdominal nodule was biopsied and pathology revealed that the atypical metastatic carcinoid had metastasized to both cutaneous and subcutaneous areas of the abdomen. Chemotherapy was then prescribed. Currently, the intrathecal drug delivery system remains in place. No local recurrence has been detected. Furthermore, we systematically reviewed clinical manifestations of the disease, pathogenesis, prognostic factors, and treatment. The metastasis rate (cutaneous and subcutaneous) was approximately 12.2%. Thirty patients (62.5%) with cutaneous and subcutaneous metastases exhibited contemporaneous lymph node invasion. The 3-, 5-, and 10-year survival rates were 44.0%, 22.0%, and 13.0%, respectively. The prognosis of patients with atypical laryngeal carcinoids was poor. Relevant prognostic factors included the level of p53, human papilloma virus status, certain hypoxic markers, and distant metastasis. No

    2016-01-01

    A cutaneous proliferative mass was identified arising from the caudal peduncle of a captive neon tetra fish (Paracheirodon innesi). The lesion was histologically consistent with an ossifying fibroma (OF), a fibro-osseous proliferative lesion typically identified in the jaws or tooth-associated supportive tissues of mammals. Although it has been previously reported, there is no recent report of this lesion occurring in a fish. This is the first report of a cutaneous ossifying fibroma in a characin fish. The authors speculate on the pathogenesis of this lesion, which may have arisen from the scale-associated mesenchymal tissues.

    Full Text Available Cutaneous horn refers to unusually cohesive keratinized material and not a true pathologic diagnosis. Though cutaneous horn has been described at various sites, horn over the penis is very rare and represents the most unusual site. The role of chronic irritation, phimosis, surgical trauma and radiotherapy have been implicated in penile horn formation. Penile horns present as elongated, keratinous, white or yellowish projections that range from a few millimeters to centimeters in size arising from the glans penis. Histopathology of the keratotic mass reveals nothing but keratin. The underlying mass may vary from verruca vulgaris to squamous cell carcinoma. The treatment is based on the pathology.

    Cutaneous dipththeria is an infectious bacterial disease endemic in tropical regions, but rarely diagnosed in Germany. Following travel in Sri Lanka, a 60-year-old German presented to our dermatological clinic with a skin ulcer and extensive erythematous erosive edema of his left foot. Corynebacterium diphtheriae was isolated from a swab of the lesion. There were no clinical signs of toxic diphtheria. The patient was treated with penicillin G and erythromycin, followed by a slow healing of the lesion. The isolated strain could be identified as toxigenic C. diphtheriae mitis. Due to increased travel activity, dermatologists should have uncommon infections like cutaneous diphtheria in mind. PMID:26525966

    2012-01-01

    Full Text Available Abnormally pigmented scars are an undesirable consequence of cutaneous wound healing and are a complication every single individual worldwide is at risk of. They present a challenge for clinicians, as there are currently no definitive treatment options available, and render scars much more noticeable making them highly distressing for patients. Despite extensive research into both wound healing and the pigment cell, there remains a scarcity of knowledge surrounding the repigmentation of cutaneous scars. Pigment production is complex and under the control of many extrinsic and intrinsic factors and patterns of scar repigmentation are unpredictable. This article gives an overview of human skin pigmentation, repigmentation following wounding and current treatment options.

    2015-10-01

    Radiation therapy is an extraordinarily effective skin-directed therapy for cutaneous T-cell lymphomas. Lymphocytes are extremely sensitive to radiation and a complete response is generally achieved even with low doses. Radiation therapy has several important roles in the management of mycosis fungoides. For the rare patient with unilesional disease, radiation therapy alone is potentially curative. For patients with more advanced cutaneous disease, radiation therapy to local lesions or to the entire skin can effectively palliate symptomatic disease and provide local disease control. Compared with other skin-directed therapies, radiation therapy is particularly advantageous because it can effectively penetrate and treat thicker plaques and tumors. PMID:26433843

    Full Text Available Cutaneous vasculitis can be classified as primary or idiopathic; or secondary, when it presents as a manifestation of connective tissue diseases, infections, drug reactions or malignancies. Although most of the idiopathic cases are self-limited and responsive to supportive measures and nonsteroidal anti-inflammatory drugs, potent immunosuppressants are sometimes required for the management of the refractory situations. Here we describe a case of a 32-year-old Caucasian female patient with history of idiopathic cutaneous deep vasculitis unresponsive to methotrexate, dapsone, and cyclophosphamide who was effectively treated with infliximab.

    TRPA1 is expressed by nociceptive neurons of the dorsal root ganglia (DRG) and trigeminal ganglia, but its roles in cold and mechanotransduction are controversial. To determine the contribution of TRPA1 to cold and mechanotransduction in cutaneous primary afferent terminals, we used the ex-vivo skin-nerve preparation from Trpa1+/+, Trpa1+/− or Trpa1−/− adult mouse littermates. Cutaneous fibers from TRPA1-deficient mice showed no deficits in acute cold sensitivity, but they displayed striking ...

    1997-03-01

    The effects of ionizing radiation, both wanted and unwanted, on regenerating tissues such as skin have traditionally exclusively been attributed to anti-proliferative activity on presumptive stem cells. The detailed mechanisms leading to clinical effects such as early erythema or late fibrosis remained largely unrevealed. In recent years this concept has been modified considerably, based on information primarily obtained by application of immunological and molecular biological methods. Concomitantly, our understanding of the skin organ as a complicated, both initiator and effector organ of the systemic immune response has enlarged dramatically, demonstrating a complex cutaneous intra- and intercellular communication network including pro- and anti-inflammatory cytokines and their receptors, adhesion molecules and surface antigens. These components regulate among others the interaction between epidermal and dermal cells, as well as microvascular endothelial cells, the latter representing the interface between the circulating immunocompetent cells (granulocytes, lymphocytes, etc) and the skin. Increasing evidence has been obtained that ionizing radiation modulates this network in a refined manner, involving transcriptional activation of immediate early (TNF-{alpha}, IL-1, -5, -6, -8, ICAM-1) as well as late (EGF-R, TGF-{beta}) responding genes. Though resembling other inflammatory conditions of the skin, a specific time and dose-dependant pattern after radiation exposure evolves, allowing a distinct discrimination between the effects of high and low single doses as well as fraction. This enlarged concept of the cutaneous radiation reaction offers new options for causal-oriented treatment with biological response modifiers including steroids and other immuno-suppressants as well as cytokines and receptor antagonists, as well as definition of optimal time windows for initiation and termination of therapeutic intervention.

    2007-02-01

    Full Text Available Abstract Background Although the sequence of events leading to wound repair has been described at the cellular and, to a limited extent, at the protein level this process has yet to be fully elucidated. Genome wide transcriptional analysis tools promise to further define the global picture of this complex progression of events. Study Design This study was part of a placebo-controlled double-blind clinical trial in which basal cell carcinomas were treated topically with an immunomodifier – toll-like receptor 7 agonist: imiquimod. The fourteen patients with basal cell carcinoma in the placebo arm of the trial received placebo treatment consisting solely of vehicle cream. A skin punch biopsy was obtained immediately before treatment and at the end of the placebo treatment (after 2, 4 or 8 days. 17.5K cDNA microarrays were utilized to profile the biopsy material. Results Four gene signatures whose expression changed relative to baseline (before wound induction by the pre-treatment biopsy were identified. The largest group was comprised predominantly of inflammatory genes whose expression was increased throughout the study. Two additional signatures were observed which included preferentially pro-inflammatory genes in the early post-treatment biopsies (2 days after pre-treatment biopsies and repair and angiogenesis genes in the later (4 to 8 days biopsies. The fourth and smallest set of genes was down-regulated throughout the study. Early in wound healing the expression of markers of both M1 and M2 macrophages were increased, but later M2 markers predominated. Conclusion The initial response to a cutaneous wound induces powerful transcriptional activation of pro-inflammatory stimuli which may alert the host defense. Subsequently and in the absence of infection, inflammation subsides and it is replaced by angiogenesis and remodeling. Understanding this transition which may be driven by a change from a mixed macrophage population to predominately M2

  13. Selective vascular injury during cutaneous laser therapy

    Tunnell, James William

    Pulsed laser irradiation in conjunction with cryogen spray cooling (CSC) can induce selective vascular injury to remove cutaneous hypervascular malformations such as port wine stains (PWS), hemangiomas, and facial veins. In this group of studies, we characterized the cryogen heat removal process and determined the effects of pulsed laser irradiation in conjunction with cryogen spray cooling of human skin. First, we employed an inverse heat conduction algorithm to measure the thermal boundary condition due to CSC in in vitro skin phantoms. Second, we developed a mathematical model of laser irradiation in conjunction with CSC in human skin. We determined tissue damage and temperature profiles due to varying combinations of laser pulse duration, radiant exposure, and CSC application times. Finally, we used ex vivo and in vivo human skin to determine the effects of high radiant exposures and CSC on epidermal and vascular injury. CSC induces a dynamic cooling effect, removing heat from the skin both during and following the spurt application time. Residual cryogen, deposited on the skin surface during the cryogen spurt, remains on the skin surface several times as long as the as cryogen spurt itself. The heat removal rate during the cryogen spurt is greatest; however, the total energy removed following the cryogen spurt is also substantial (approximately half as much as during the spurt application time). CSC was effective in protecting the human skin epidermis in light to moderately pigmented skin. Mathematical modeling, ex vivo, and in vivo studies showed that the epidermal damage threshold could be increased by a factor of approximately two. Increased radiant exposures increased the risk of non-selective vascular injury observed in histology as injury to the epidermis and perivascular collagen; however, proper choice of cryogen cooling durations resulted in the elimination of epidermal injury as well as perivascular tissue injury. In addition, higher radiant

    2009-01-01

    Little is known about the metabolising capacity of the human skin in relation to topically applied drugs and formulations. We chose lidocaine as a model compound since the metabolic pathways are well known from studies concerning hepatic metabolism following systemic drug administration. However......, the enzymes involved are also expressed in the skin. Hence, the aim of the current study was to investigate the extent of the cutaneous in vivo metabolism of topically applied lidocaine in human volunteers. A dose of 5 mg/cm(2) of Xylocaine(R) (5% lidocaine) ointment was applied onto the buttock skin...... of the volunteers. After 2 h, residual formulation was removed, and two 4-mm punch biopsies were taken from each volunteer. The quantity of lidocaine extracted from the skin samples (epidermis + dermis) was 109 +/- 43 ng/mm(2) skin. One metabolite (monoethylglycine xylidide, MEGX) was detected in...

    Full Text Available Cutaneous horn is a conical, dense, and hyperkeratotic protrusion that often appears similar to the horn of an animal. Giant cutaneous horns are rare; no incidence or prevalence has been reported. The significance of cutaneous horns is that they occur in association with, or as a response to, a wide variety of underlying benign, premalignant, and malignant cutaneous diseases. A case of giant cutaneous horn of left oral commissure along with carcinoma left buccal mucosa is reported here as an extremely rare oral/perioral pathology.

    Ionizing radiation is an important treatment modality for a variety of malignant conditions. However, development of radiation-induced skin changes is a significant adverse effect of radiation therapy (RT). Cutaneous repercussions of RT vary considerably in severity, course, and prognosis. When they do occur, cutaneous changes to RT are commonly graded as acute, consequential-late, or chronic. Acute reactions can have severe sequelae that impact quality of life as well as cancer treatment. Thus, dermatologists should be informed about these adverse reactions, know how to assess their severity and be able to determine course of management. The majority of measures currently available to prevent these acute reactions are proper skin hygiene and topical steroids, which limit the severity and decrease symptoms. Once acute cutaneous reactions develop, they are treated according to their severity. Treatments are similar to those used in prevention, but incorporate wound care management that maintains a moist environment to hasten recovery. Chronic changes are a unique subset of adverse reactions to RT that may develop months to years following treatment. Chronic radiation dermatitis is often permanent, progressive, and potentially irreversible with substantial impact on quality of life. Here, we also review the etiology, clinical manifestations, pathogenesis, prevention, and management of late-stage cutaneous reactions to radiotherapy, including chronic radiation dermatitis and radiation-induced fibrosis.

    Angiosarcoma (AS) is a rare neoplasm. Cutaneous AS is the most common form of AS. The epithelioid variant of the disease, however, is a rare entity. This subset can histologically mimic non-vascular neoplasms and impose serious challenges in reaching the correct diagnosis. We present five patients with cutaneous epithelioid angiosarcoma (EAS); in none, the clinical diagnosis included a vascular lesion. Three patients had history of breast conservation surgery with/without radiation therapy. Other patients had no previous radiation, and there was no lymphedema in any of the cases. The histopathological examination of the biopsy specimens by hematoxylin and eosin method was not suggestive of a malignant vascular neoplasm initially and the differential diagnoses included carcinoma, malignant melanoma and atypical lymphoid infiltrate. Only after performing immunohistochemical studies that included vascular markers, a definitive diagnosis was possible. Some cases showed unusual histopathological features. Cutaneous EAS is a rare variant of cutaneous AS that can mimic a variety of more common, non-vascular neoplasms, creating a major pitfall in the diagnosis. A careful and thorough histopathological examination and a high index of suspicion, along with appropriate immunohistochemical evaluation, can help reach a correct diagnosis and provide optimal patient care.

    Full Text Available BACKGROUND Anthrax is a disease of herbivorous animals. Humans incidentally acquire the cutaneous disease by handling infected dead animals and their products. Sporadic cases of human anthrax have been reported from Southern India. METHODS Fifteen tribal men, one woman, one child from various places near Paderu presented with painless ulcers associated with vesiculation and oedema of the surrounding skin on the extremities without any constitutional symptoms. There was a history of slaughtering and consumption of a dead goat ten days - 2 weeks prior to the development of skin lesions. Three days later another 19 members came from the same area with same complaints. Clinically, cutaneous anthrax was suspected and smears, swabs, and punch biopsies were taken for culture and identification by Polymerase Chain Reaction (PCR. All the cases were treated with intravenous antibiotics followed by oral antibiotics. Appropriate health authorities were alerted and proper control measures were employed. RESULTS Smears from the cutaneous lesions of some patients were found to be positive for Bacillus anthracis and this was confirmed by polymerase chain reaction. All the cases responded to antibiotics. CONCLUSION We report thirty six cases of cutaneous anthrax in a non-endemic district, Visakhapatnam, Andhra Pradesh.

    The aim of study was to describe clinico histopathological manifestations of cutaneous and gastric habronemiasis in horse. The adult worms live on the wall of the stomach and cutaneous of the host without internal migration. A 5 year old 700 kg warm-blood, cross gelding was referred to the Tehran School of Veterinary Medicine, Veterinary Teaching Hospital. The horse presented skin lesions around. In our survey, several raised granulomatous nodules with a cystic space and parasites within the cysts were observed. Also gastric rupture at greater curvature due to abscess and perforation through the serosa causing diffused peritonitis and subsequent death. Eosinophils and other inflammatory cells were present in large numbers. Furthermore, cutaneous lesions were characterized by single or multiple ulcerated timorous masses with eosinophil epithelioid cell infiltration and scattered necrotic debris. Granulation tissue and neutrophils were observed along the ulcerated area. In this report a case of cutaneous and gastric habronemiasis in a horse in Iran is described with special attention to confirmation of the clinical diagnosis. PMID:27605815

    2015-02-01

    The most recent pediatric vasculitis classifications (EULAR/PRINTO/PRES) have proposed the use of an integration of clinical signs and symptoms, laboratory data, imaging and pathologic data. Pediatric vasculitis represent a peculiar clinical-diagnostic model, compared to the corresponding adult pathology chapter, and in particular, dermatopathologic aspects of these diseases identify more specific issues, made contingent by crucial variables such as duration of vasculitis lesion, site of the biopsy, proper biopsy depth, and possibility to correlate histopathological findings with immunopathological results. Possible additional diagnostic difficulties may arise from the fact that, in children, the same systemic disease, such as lupus erythematosus, may present with different clinical manifestations, with histopathological features of a precise type of vasculitis specific for that type of clinical manifestation. Examples are provided by hypocomplementemic urticarial vasculitis, cryoglobulinemic purpura, lymphocytic vasculitis of livedoid lesions. This paper describes the cutaneous histopathological findings of some vasculitis related pediatric diseases, be they pertaining to a systemic vasculitis with corresponding cutaneous vasculitis, to a systemic vasculitis with sporadic cutaneous vasculitic involvement, and to a systemic vasculitis without cutaneous vasculitic involvement. Type and level of histopathological vasculitic involvement, caliber of the vessel, type of vasculitis associated infiltrate, are likewise reliable integration in the complex diagnostic path of vasculitis in childhood. On the basis of these criteria dermatopathologists should be confident in identifying the type of the vasculitis and relate them to a specific pediatric disease. PMID:25516220

    Full Text Available Rice grain is one of the world's most important food crops, and its cultivation is a major occupation in Anambra State, Nigeria. These rice farmers are exposed to various agents that predispose them to cutaneous mycoses. The aim of this work was to screen rice farmers for lesions suggestive of cutaneous mycoses and to isolate and identify fungal agents associated with the infection. This survey was carried out between November 2009 and June 2011 in Anambra State, Nigeria. Clinical samples collected from 201 farmers with lesions suggestive of cutaneous mycoses were processed and the organisms identified. Questionnaires were used to obtain other necessary data and were statistically analyzed. Of the 2,580 rice farmers screened, 201 (7.79% showed positive lesions. Organisms recovered included Microsporum audouinii, Microsporum ferrugineum, Trichophyton megnini, Trichophyton tonsurans, Trichophyton rubrum, Aspergillus terrus, Aspergillus candidus, Aspergillus scleriotorum, Aspergillus niger, Aspergillus flavus, Scopulariopsis sp., Chrysosporium sp., Eupenicillium javanicum, Fusarium sp., Penicillium aculeatum, and Penicillium pinophilum. At the end of this work, onychomycosis was observed to be the most prevalent with nondermatophyte molds now becoming very important agents of cutaneous mycoses among rice farmer.

    Full Text Available Smooth muscle tumors rather benign or malignant can arise wherever the muscular tissue presents but cutaneous leiomyoma is one of the rare benign tumors of the which even the diagnostic criteria from the malignant type of the tumor is still in doubt. This study was aimed to compare the subtypes of cutaneous leiomyoma from different histologic aspects in order to find unique criteria for better classification and diagnosis. The six year data base of our center was reviewed and 25 patients with cutaneous leiomyoma were included in this study. Of 25 patients, 5 were female and 20 were male. 5 patients had angioleiomyoma (ALM and 20 had pilar leiomyoma (PLM. ALM had following characteristics: dilated vascular canals intermingled with compact smooth muscle bundles; well circumscribe counter and myxoid and hyaline changes through the tumor. In contrast, PLMs had following histologic features: poor defined outline, entrapped hair follicles and eccrine glands, acanthosis and elongated rete ridges with hyperpigmentation and smooth muscle bundles which are interdigitated with elongated rete ridges. Here we introduced some distinct histological features for each subtype of the cutaneous leiomyoma which can lead to create novel criteria for classification and diagnosis of the lesion.

  16. Sentinel lymph node biopsy in local recurrence of cutaneous melanoma

    International Nuclear Information System (INIS)

    Full text: Locally recurrent disease in patients with melanoma is usually defined as cutaneous or subcutaneous arising within 5 cm of the primary site after complete excision of the primary lesion. It may represent residual disease not excised with the primary tumor or the outgrowth of the satellite lesions, which are common with melanoma. Lymphatic mapping and sentinel lymph node (SLN) biopsy is highly accurate in staging nodal basins at risk of regional metastases in primary melanoma patients and identifies those who may benefit from earlier lymphadenectomy. Our purpose was to evaluate the efficacy of sentinel lymph node mapping and biopsy in local recurrence of cutaneous melanoma when the primary lesion was less than 1.0mm thick. Three patients with local recurrence of cutaneous melanoma underwent sentinel lymph node mapping and biopsy. All patients underwent preoperative lymphoscintigraphy to identify the lymphatic basin and the site of the sentinel node. All patients subsequently underwent intra-operative lymphatic mapping and selective lymph node biopsy with vital blue dye and hand-held gamma probe. Excised SLN were analysed by conventional histological staining (H and E) and immunohistochemical staining. In all patients the lymphatic mapping and sentinel lymph node biopsy was successful. The SLN biopsy was negative in two patients and positive in one who underwent therapeutic lymph node dissection. Our results indicate that the SLN mapping and biopsy is also possible in patients having local recurrence of cutaneous melanoma. Although long-term results are not available, early results are promising. (author)

    Okwor, Ifeoma; Uzonna, Jude

    2009-05-01

    One might think that the development of a vaccine against cutaneous leishmaniasis would be relatively straightforward because the type of immune response required for protection is known and natural immunity occurs following recovery from primary infection. However, there is as yet no effective vaccine against the disease in humans. Although vaccination in murine studies has yielded promising results, these vaccines have failed miserably when tested in primates or humans. The reasons behind these failures are unknown and remain a major hurdle for vaccine design and development against cutaneous leishmaniasis. In contrast, recovery from natural, deliberate or experimental infections results in development of long-lasting immunity to re-infection. This so called infection-induced resistance is the strongest anti-Leishmania immunity known. Here, we briefly review the different approaches to vaccination against cutaneous leishmaniasis and argue that vaccines composed of genetically modified (attenuated) parasites, which induce immunity akin to infection-induced resistance, may provide best protection against cutaneous leishmaniasis in humans.

    2013-01-01

    Full Text Available Background: The microbiologic diagnosis of cutaneous tuberculosis is difficult because most lesions harbor only a small number of mycobacteria that cannot usually be detected by staining for the organism or by culture. Nucleic acid amplification tests based on the polymerase chain reaction (PCR are potentially useful in this situation. Aims: To evaluate the utility of mRNA PCR and DNA PCR in the diagnosis of cutaneous tuberculosis. Methods: Biopsies from 28 cases of cutaneous tuberculosis and 19 controls with other diseases were subjected to microbiologic tests including direct smears for mycobacteria, culture and both mRNA PCR and DNA PCR. The laboratory was blinded to the clinical diagnosis. Results: None of the patients or controls showed a positive reaction on mRNA PCR test. Seven of 28 cases and 5 out of 19 controls showed a positive result on DNA PCR test yielding a sensitivity of 25% and a specificity of 73.7%. Conclusion: The results of PCR tests in cutaneous tuberculosis should be interpreted in the light of clinical and histopathological findings.

    Full Text Available Abstract Background Pentavalent antimonials (Sb5 and miltefosine are the first-line drugs for treating cutaneous leishmaniasis in Colombia; however, toxicity and treatment duration negatively impact compliance and cost, justifying an active search for better therapeutic options. We compared the efficacy and safety of thermotherapy and meglumine antimoniate for the treatment of cutaneous leishmaniasis in Colombia. Method An open randomized Phase III clinical trial was performed in five military health centres. located in northwestern, central and southern Colombia. Volunteers with parasitological positive diagnosis (Giemsa-stained smears of cutaneous leishmaniasis were included. A single thermotherapy session involving the application of 50°C at the center and active edge of each lesion. Meglumine antimoniate was administered intramuscularly at a dose of 20 mg Sb5/kg weight/day for 20 days. Results Both groups were comparable. The efficacy of thermotherapy was 64% (86/134 patients by protocol and 58% (86/149 by intention-to-treat. For the meglumine antimoniate group, efficacy by protocol was 85% (103/121 patients and 72% (103/143 by intention-to-treat, The efficacy between the treatments was statistically significant (p 0.01 and Leishmania species responsible for infection. The side effects of meglumine antimoniate included myalgia, arthralgia, headache and fever. Regarding thermotherapy, the only side effect was pain at the lesion area four days after the initiation of treatment. Conclusion Although the efficacy rate of meglumine antimoniate was greater than that of thermotherapy for the treatment of cutaneous leishmaniasis, the side effects were also greater. Those factors, added to the increased costs, the treatment adherence problems and the progressive lack of therapeutic response, make us consider thermotherapy as a first line treatment for cutaneous leishmaniasis.

    The clinical laboratory diagnosis of cutaneous anthrax is generally established by conventional microbiological methods, such as culture and directly straining smears of clinical specimens. However, these methods rely on recovery of viable Bacillus anthracis cells from swabs of cutaneous lesions and often yield negative results. This study developed a rapid protocol for detection of B. anthracis on clinical swabs. Three types of swabs, flocked-nylon, rayon, and polyester, were evaluated by 3 extraction methods, the swab extraction tube system (SETS), sonication, and vortex. Swabs were spiked with virulent B. anthracis cells, and the methods were compared for their efficiency over time by culture and real-time PCR. Viability testing indicated that the SETS yielded greater recovery of B. anthracis from 1-day-old swabs; however, reduced viability was consistent for the 3 extraction methods after 7 days and nonviability was consistent by 28 days. Real-time PCR analysis showed that the PCR amplification was not impacted by time for any swab extraction method and that the SETS method provided the lowest limit of detection. When evaluated using lesion swabs from cutaneous anthrax outbreaks, the SETS yielded culture-negative, PCR-positive results. This study demonstrated that swab extraction methods differ in their efficiency of recovery of viable B. anthracis cells. Furthermore, the results indicated that culture is not reliable for isolation of B. anthracis from swabs at ≥ 7 days. Thus, we recommend the use of the SETS method with subsequent testing by culture and real-time PCR for diagnosis of cutaneous anthrax from clinical swabs of cutaneous lesions. PMID:23035192

    Cutaneous body image, defined as the individual's mental perception of the appearance of their skin, hair and nails, is an important psychodermatological element in skin diseases. To measure individuals' cutaneous body image, a practical and accurate instrument is necessary. In this study, we translated the Cutaneous Body Image Scale (CBIS), a 7-item instrument originally created by Gupta et al. in 2004, into Japanese using a forward- and back-translation method and evaluated the reliability and validity of the instrument by psychometric tests. A total of 298 healthy adults (64 men and 234 women, aged 28.9 +/- 9.9 years) and 165 dermatology patients (56.7% eczema/dermatitis, 9.8% acne, 7.5% alopecia, 6.9% psoriasis, 19.1% skin tumor/fleck/other) (30 men and 135 women, aged 37.9 +/- 15.2 years) responded to the Japanese version of the CBIS. The internal-consistency reliability of the instrument was high (Cronbach's alpha, healthy adults 0.88, patients 0.84). The CBIS measure demonstrates good test-retest reliability (healthy adults gamma = 0.92, P Skindex-16 in healthy adults (gamma = -0.397 and -0.373, respectively) and in patients (gamma = -0.431 and -0.38, respectively). A stepwise multiple regression analysis revealed that an emotional aspect of skin-condition related quality of life was the best predictor of cutaneous body image in both healthy adults and patients (beta = -0.31 and -0.41, respectively) followed by "body dissatisfaction" (beta = -0.17, and -0.23, respectively). Adjusted R(2) was 0.246 in healthy adults and 0.264 in patients. These were consistent with the results from the original the CBIS. These results suggest that the Japanese version of the CBIS is a reliable and valid instrument to measure the cutaneous body image of Japanese adults and also dermatology patients. PMID:19712274

    Full Text Available Clinicians often experience delayed epithelialization in diabetic patients, for which a high glucose condition is one of the causes. However, the mechanisms underlying delayed wound closure have not been fully elucidated, and effective treatments to enhance epithelialization in patients with hyperglycaemia have not been established. Here we propose a new reagent, acylated homoserine lactone (AHL, to improve the delayed epithelialization due to the disordered formation of a basement membrane of epidermis in hyperglycaemic rats. Acute hyperglycaemia was induced by streptozotocin injection in this experiment. Full thickness wounds were created on the flanks of hyperglycaemic or control rats. Histochemical and immunohistochemical analyses were performed to identify hyperglycaemia-specific abnormalities in epidermal regeneration by comparison between groups. We then examined the effects of AHL on delayed epithelialization in hyperglycaemic rats. Histological analysis showed the significantly shorter epithelializing tissue (P < 0.05, abnormal structure of basement membrane (fragmentation and immaturity, and hypo- and hyperproliferation of basal keratinocytes in hyperglycaemic rats. Treating the wound with AHL resulted in the decreased abnormalities of basement membrane, normal distribution of proliferating epidermal keratinocytes, and significantly promoted epithelialization (P < 0.05 in hyperglycemic rats, suggesting the improving effects of AHL on abnormal epithelialization due to hyperglycemia.

  12. Topical Administration of Manuka Oil Prevents UV-B Irradiation-Induced Cutaneous Photoaging in Mice

    Full Text Available Manuka tree is indigenous to New Zealand, and its essential oil has been used as a traditional medicine to treat wounds, fever, and pain. Although there is a growing interest in the use of manuka oil for antiaging skin care products, little is known about its bioactivity. Solar ultraviolet (UV radiation is the primary environmental factor causing skin damage and consequently premature aging. Therefore, we evaluated manuka oil for its effects against photoaging in UV-B-irradiated hairless mice. Topical application of manuka oil suppressed the UV-B-induced increase in skin thickness and wrinkle grading in a dose-dependent manner. Application of 10% manuka oil reduced the average length, depth, and % area of wrinkles significantly, and this was correlated with inhibition of loss of collagen fiber content and epidermal hyperplasia. Furthermore, we observed that manuka oil could suppress UV-B-induced skin inflammation by inhibiting the production of inflammatory cytokines. Taken together, this study provides evidence that manuka oil indeed possesses antiphotoaging activity, and this is associated with its inhibitory activity against skin inflammation induced by UV irradiation.

  13. Topical mechlorethamine: cutaneous changes in patients with mycosis fungoides after its administration

    Price, N.M.

    1977-10-01

    Six patients with mycosis fungoides were treated with topical mechlorethamine hydrochloride for periods of two to four years. Clinical and histological studies for radiomimetic and radiodermatitis-like effects failed to demonstrate any abnormalities. The only observed changes were generalized hyperpigmentation of the skin and melanin-containing melanophages in the papillary dermis. We consider that the long-term use of topical mechlorethamine may be a safe form of therapy, but that a continuous indefinite follow-up of patients on this medication should be mandatory.

  14. Treatment and follow-up of patients suffering from the cutaneous radiation syndrome

    International Nuclear Information System (INIS)

    inflammation were stopped. The most remarkable result was the reduction of radiation fibrosis: sonographically determined skin thickness partly returned to normal levels after treatment of months with Interferon gamma 50μg s.c. 3 week. Based upon therapeutic experience with patients undergoing radiation therapy, symptomatic relief of pruritus can be achieved by administration of nonsedating antihistamines, such as Loratadine. In the chronic stage of the CRS after radiation therapy, where interferon gamma cannot be used, reduction of radiation-induced cutaneous fibrosis can be reached by a combination of Vitamin E and pentoxyfiline even two decades after radiation exposure. It is concluded that under accidental partial body exposure with high doses of beta and gamma irradiation, the predominant involvement of the skin, described as the cutaneous radiation syndrome, may become the characteristic trait of this increasingly probable accident pattern. Through treatment is complex and requires dermatological and radiobiological expertise, it results in marked clinical improvement of the affected patients. These results demonstrate that considerable progress has been achieved during the last years regarding diagnosis and treatment of cutaneous radiation sequelae. Surgery has to be considered the treatment of choice for radiation carcinoma, but is no longer the only available therapeutic option. However, systematic controlled clinical trials are still missing for these options

    2013-11-01

    Estimated worldwide incidence of tegumentary leishmaniasis (cutaneous leishmaniasis [CL] and mucocutaneous leishmaniasis [MCL]) is over 1.5 million cases per year in 82 countries, with 90 % of cases occurring in Afghanistan, Brazil, Iran, Peru, Saudi Arabia and Syria. Current treatments of CL are poorly justified and have sub-optimal effectiveness. Treatment can be based on topical or systemic regimens. These different options must be based on Leishmania species, geographic regions, and clinical presentations. In certain cases of Old World CL (OWCL), lesions can spontaneously heal without any need for therapeutic intervention. Local therapies (thermotherapy, cryotherapy, paromomycin ointment, local infiltration with antimonials) are good options with less systemic toxicity, reserving systemic treatments (azole drugs, miltefosine, antimonials, amphotericin B formulations) mainly for complex cases. The majority of New World CL (NWCL) types require systemic treatment (mainly with pentavalent antimonials), either to speed the healing or to prevent dissemination to oral-nasal mucosa as MCL (NWMCL). These types of lesions are potentially serious and always require systemic-based regimens, mainly antimonials and pentamidine; however, the associated immunotherapy is promising. This paper is an exhaustive review of the published literature on the treatment of OWCL, NWCL and NWMCL, and provides treatment recommendations stratified according to their level of evidence regarding the species of Leishmania implicated and the geographical location of the infection.

    Wilson, Thad E.; Cui, Jian; Crandall, Craig G.

    2002-01-01

    Animal studies suggest that alpha-adrenergic-mediated vasoconstriction is compromised during whole-body heating. The purpose of this study was to identify whether whole-body heating and/or local surface heating reduce cutaneous alpha-adrenergic vasoconstrictor responsiveness in human skin. Protocol I: Six subjects were exposed to neutral skin temperature (i.e., 34 degrees C), whole-body heating, and local heating of forearm skin to increase skin blood flow to the same relative magnitude as that observed during whole-body heating. Protocol II: In eight subjects forearm skin was locally heated to 34, 37, 40, and 42 degrees C. During both protocols, alpha-adrenergic vasoconstrictor responsiveness was assessed by local delivery of norepinephrine (NE) via intradermal microdialysis. Skin blood flow was continuously monitored over each microdialysis membrane via laser-Doppler flowmetry. In protocol I, whole-body and local heating caused similar increases in cutaneous vascular conductance (CVC). The EC50 (log NE dose) of the dose-response curves for both whole body (-4.2 +/- 0.1 M) and local heating (-4.7 +/- 0.4 M) were significantly greater (i.e., high dose required to cause 50% reduction in CVC) relative to neutral skin temperature (- 5.6 +/- 0.0 M; Pbody heated conditions CVC did not return to pre-heating values even at the highest dose of NE. In protocol II, calculated EC50 for 34, 37, 40, and 42 degrees C local heating was - 5.5 +/- 0.4, -4.6 +/- 0.3, -4.5 +/- 0.3, - 4.2 +/- 0.4 M, respectively. Statistical analyses revealed that the EC50 for 37,40 and 42 degrees C were significantly greater than the EC50 for 34 degrees C. These results indicate that even during administration of high concentrations of NE, alpha-adrenergic vasoconstriction does not fully compensate for local heating and whole-body heating induced vasodilatation in young, healthy subjects. Moreover, these data suggest that elevated local temperatures, above 37 degrees C, and whole-body heating

    2014-06-01

    MicroRNAs (miRNAs) have emerged as key post-transcriptional regulators of gene expression, and have displayed important roles in areas spanning from embryonic development to skin physiology. Despite this, till now little is known about the significance of miRNAs in cutaneous wound healing. In this mini-review, we discuss the existing evidence on the roles of miRNAs in physiological processes relevant to cutaneous wound healing, followed by a highlight of the prospects and challenges of future development of miRNA-based wound therapies. With existing technologies of nucleic acid transfer and miRNA modulation, it is anticipated that once the roles of miRNAs in wound healing have been clarified, there will be a vast new vista of opportunities brought up for development of miRNA-targeted therapies for wound care.

    @@ Infections caused by opportunistic organisms which have been known as etiologic agents of disease become more and more frequent.Aspergillus spp. is one of the agents. Fungi of aspergillus genus are widely distributed in nature, particularly in the soil and in the decomposed vegetation. They are frequent opportunist pathogens in immunocompromised patients. The most frequent causative organisms that cause cutaneous aspergillosis are A.fumigatus and A.flavus.1-3 In this report, we present a case of primary cutaneous aspergillosis manifested by ulceration of the shank due to A. flavus. The patient had no deficiency of immunological status and severe disease associated with fungal infection. Excellent response was shown to anti-fungal therapy.

    2004-05-01

    We retrospectively analyzed the first 461 cases entered into our cutaneous lymphoma database and found 285 cases of mycosis fungoides. We also identified 6 cases of malignant melanoma, all of which were found in patients with mycosis fungoides. The crude rate of melanoma in the general population in England, United Kingdom, in 1998 was 8.8/100,000 in men and 11.4/100,000 in women. The incidence of melanoma found in our cohort of patients with mycosis fungoides was far higher, and in 4 of the 6 patients cannot be explained on the basis of prior therapy. The reason for this association is unclear, but this report emphasizes the risk of second malignancies for patients with cutaneous T-cell lymphoma and melanoma.

    Cutaneous leishmaniasis is found in all the four provinces of Pakistan; these are NWFP, Balochistan, Sindh and Punjab. In Balochistan the areas from where the patients came are Uthal, Quetta and Ormara. The highest number of patients came from Quetta and least from Ormara. The patients included in this study were from the Mangopir and Chakewara, areas of Karachi. The infection is endemic in this country and the recent epidemics in the Dadu District and Nawabshah indicate its importance in the locality. The sand fly vector is found in all four provinces of Pakistan that are listed here. It is quite obvious that presence of leishmaniasis indicates the presence of sand flies and cutaneous leishmaniasis is more common.

    Full Text Available Cutaneous leishmaniasis affects millions of people around the world. Several species of Leishmania infect mouse strains, and murine models closely reproduce the cutaneous lesions caused by the parasite in humans. Mouse models have enabled studies on the pathogenesis and effector mechanisms of host resistance to infection. Here, we review the role of nitric oxide (NO, reactive oxygen species (ROS, and peroxynitrite (ONOO− in the control of parasites by macrophages, which are both the host cells and the effector cells. We also discuss the role of neutrophil-derived oxygen and nitrogen reactive species during infection with Leishmania. We emphasize the role of these cells in the outcome of leishmaniasis early after infection, before the adaptive Th-cell immune response.

    Full Text Available A 45-year-old man with reactivation of previously existing and subsiding cutaneous leishmaniasis on his wrist and lower leg (shin after renal transplantation was admitted to our dermatology service on March 2008. He presented to us with two huge tumoral and cauliflower-like lesions. Skin smear and histopathology of skin showed leishman bodies and confirmed the diagnosis. After renal transplantation, he received cyclosporine plus prednisolone to induce immunosuppression and reduce the probability of transplant rejection. After immunosuppressive therapy, reactivation of cutaneous leishmaniasis with the above presentation took place. The patient responded to 800 mg/day intravenous sodium stibogluconate for 3 weeks plus local cryotherapy. Systemic plus local therapy along with reducing the doses of immunosuppressive drugs led to improvement of lesions. Reactivation of leishmaniasis after immunosuppression has been rarely reported.

    Full Text Available Metastasis to the skin in laryngeal squamous cell carcinoma is an extremely rare occurrence. We report a case of multiple cutaneous metastases in the follow-up of a 60-year-old male with squamous carcinoma of the vocal cords that were treated with surgery and radiotherapy. The patient presented with multiple painful skin nodules at 3 months following the completion of treatment. Clinically the skin nodules mimicked an inflammatory skin lesion. The diagnosis of metastatic skin lesions was made by cytological examination. Appearance of new painful skin lesions soon after the completion of treatment in patients treated for squamous carcinoma of the larynx should warrant a clinical suspicion of cutaneous metastases.

    Full Text Available Lichen myxoedematosus (LM, a form of primary cutaneous mucinosis, may present either as localized less severe form called papular mucinosis or diffuse more severe form called scleromyxoedema. The diffuse form is almost always associated with monoclonal gammopathy, whereas localized form is not. We report an atypical case of localized form of LM associated with multiple myeloma in a 66-year-old male, who presented with asymptomatic waxy papular eruption on extremities, which on histopathological examination confirmed the diagnosis of cutaneous mucinosis. After initially being put on steroids and hydroxychloroquine with minimal improvement, patient subsequently presented with encephalopathy and on evaluation revealed hypernatremia, hypercalcemia, hypergammaglobulinemia, reversal of albumin-globulin (A/G ratio, azotemia, and lytic lesions in skull X-ray. Bone marrow aspiration and biopsy confirmed multiple myeloma. Patient was successfully treated with standard treatment regimen for multiple myeloma with bortezumib and dexamethasone and his skin lesions subsided completely.

    Reverse total shoulder arthroplasty is becoming a common form of shoulder arthroplasty that is often performed in the setting of rotator cuff pathology. Infection is a rare complication but is more common in reverse total shoulder arthroplasty than in hemiarthroplasty or anatomic total shoulder arthroplasty. We present the case of a 69-year-old patient with a reverse total shoulder arthroplasty who presented with purulent drainage from the skin of his anterior shoulder. Computed tomography arthrogram confirmed the presence of a synovial cutaneous fistula. Synovial cutaneous fistula is a rare variant of periprosthetic infection that, to our knowledge, has not been described previously in the setting of a reverse total shoulder arthroplasty. Computed tomography arthrogram proved to be a reliable method for confirming the diagnosis and was used for operative planning to remove the hardware. PMID:27257460

    Full Text Available The primary cutaneous lymphomas are often indolent but difficult to treat. In the early stages psoralen and ultraviolet-A therapy is the standard treatment whereas at the tumor stage chemotherapy (e.g. pegylated doxorubicin is often used for debulking. The purine analog 2-chlorodeoxyadenosine (2CdA acts in non-Hodgkin’s lymphoma and has been used in our center for the treatment of advanced primary cutaneous T-cell lymphomas (CTCL. Here, we report on the efficacy and side effects of 2CdA in six patients with CTCL. One patient died owing to myelosuppression. Partial responses were seen in four cases but full remission was observed in only one case. We concluded that 2CdA has a limited usefulness in the management of advanced CTCL.

    1981-01-01

    To obtain information about the role of local proliferation in the pathogenesis of dermal infiltrate in malignant cutaneous lymphomas, we determined the percentage of /sup 3/H-thymidine-labeled infiltrating cells (/sup 3/H-index). A linear correlation was found between proliferative activity and clinical stage in mycosis fungoides, i.e., the /sup 3/H-index is moderately elevated in stage I and high in stage III. The /sup 3/H-index is within normal range in dermal infiltrate of Sezary syndrome, diffuse lymphocytic lymphoma, as well as in lymphocytoma benigna cutis. In parapsoriasis en plaques two groups can be distinguished: in the small plaque variant (chronic superficial dermatitis) the /sup 3/H-index is low, whereas the large-plaque variant (prereticulotic poikiloderma) shows strong proliferative activity. Thus, determination of proliferative activity seems to give new insights into the pathogenesis of dermal infiltrate in cutaneous lymphomas.

    Antiphospholipid antibody syndrome (APS) is an acquired thrombophilia, caused by autoantibodies to anticardiolipin (aCL), or antibeta 2 glycoprotein I, or the presence of lupus anticoagulant (LA) in plasma. It is characterized by recurrent venous and/or arterial thrombi and/or pregnancy related morbidities. We present the case of a 52-year-old female with long-standing APS, who developed cutaneous vasculitis following a common cold. Most of the cutaneous manifestations of APS have been found to be thrombotic on histopathology without evidence of perivascular inflammation. Vasculitis is usually seen in APS patients with coexistent Systemic Lupus Erythematosus (SLE). However, our patient had evidence of vasculitis on skin biopsy and did not have SLE. Though rare, this is a disease process which must be considered in patients with primary APS which must be closely monitored for other vasculitic complications of APS, particularly diffuse alveolar hemorrhage.

    Primary cutaneous anaplastic large-cell lymphoma (PCALCL) is a part of the spectrum of CD30+ lymphoproliferative cutaneous processes. The characteristics include single or multifocal nodules that ulcerate as skin lesion, slow disease progression, autoregressive, and recurrent in few years. The present study report the case of a 16-year-old boy presenting PCALCL with single nodules, ulcer, keloid, and scab in his right-side face. He showed a good response to the treatment with systemic chemotherapy and dermatoplasty, and regained confidence after the appearance of recovery. There is no relapse of the primary lesion and organs involved till now. The chemotherapy combining with surgical excision and dermatoplasty is a good method for PCALCL, per the lesion biopsy and positron emission tomography-computed tomography before and after treatment.

    Full Text Available INTRODUCTION: There are various approaches to the treatment of cutaneous tumors; one of them is treatment with imiquimod, a synthetic toll-like receptor agonist with a low molecular weight that offers a topical, noninvasive, and non-surgical therapeutic option. The main objective of our study was to provide data on 89 patients who used a 5% imiquimod cream for the treatment of cutaneous tumors at the Cutaneous Oncology Group of the Dermatology Department of Hospital das Clinicas from 2003 to 2008. MATERIALS AND METHODS: Here, we present our experience in the treatment of 123 cutaneous tumors of various types, including basal cell carcinoma (BCC, squamous cell carcinoma (SCC, Bowen's disease, erythroplasia of Queyrat, Paget's disease, and trichoepithelioma, with 5% imiquimod cream from 2003 to 2008 in the Cutaneous Oncology Group of the Dermatology Department of Hospital das Clinicas. Patients were divided into two separate groups according to their diagnosis and comorbidities; these comorbidities included epidermodysplasia verruciformis, xeroderma pigmentosum, albinism, basal cell nevus syndrome, Brooke-Spiegler syndrome, HIV, chronic lymphocytic leukemia, B-cell lymphoma, and kidney transplantation. Treatment duration, response to imiquimod, follow-up, recurrence, and local and systemic reactions associated with use of the drug were analyzed. Epidemiological data were obtained and cure rates were calculated. RESULTS: The ratio of women to men was 1.28:1, and the mean age was 63.1 years. Tumors were located mainly on the face, back, trunk, and legs. For patients with comorbidities, the overall cure rate was 38%. These specific patients demonstrated cure rates of 83.5% for superficial BCC and 50% for Bowen's disease. Aggressive BCC and superficial and nodular BCC did not present a good response to treatment. Trichoepitheliomas and nodular BCC showed a partial response, and erythroplasia of Queyrat showed a complete response. For patients without

    Objective To identify Mycobacterium marinum (M. marinum) inducing misdiagnosis and treatment failure.Methods The lesional specimen of patient with cutaneous M. marinum were cultivated on Lwenstein-Jensen medium. The isolate was identified by biochemical tests and polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) analysis of the hsp65 gene.Results Smooth and non-pigmented colonies were noted after incubation at 32 ℃ for 2 weeks. The isolate was acid-fast bacilli and confirmed as M. marinum by biochemical tests and PCR-RFLP.Conclusion For a correct diagnosis of cutaneous M. marinum infection, it is crucial for clinicians to have a high index of suspicion, obtain the history of exposure and trauma and understand growth characteristics of the organism. Compared with conventional biochemical techniques, PCR-RFLP analysis is a more rapid, accurate and reliable method for mycobacterial identification to species level.

It usually appears as a pink or light-brown, smooth-surfaced, well-circumscribed and asymptomatic papulonodular lesion. A large group of dermatologic disorders should be considered in the differential diagnosis. Herein we present a case of Spitz nevus with a two month history of a nodular lesion on the earlobe which mimicks cutaneous leishmaniasis clinically.

    Objective: To describe and compare the epidemiological features of anthroponotic cutaneous leishmaniasis (ACL) caused by Leishmania tropica, and zoonotic cutaneous leishmaniasis (ZCL) due to Leishmania major in Morocco. Methods: We performed a retrospective study of ZCL and ACL cases reported during the last ten years in Morocco (2004–2013). Epidemiological data were analyzed by using Pearson's correlation method as well as Tukey test and digital maps were produced for incidence repartition calculated by using ArcMap GIS version 10. Results: A total of 41 656 cases of cutaneous leishmaniasis were notified between 2004 and 2013 in Morocco. The mean incidence was 139 cases/100 000 population/10 years and it was significantly higher in 2010. In the spatial context, ACL form was the most common in Morocco, while ZCL was the most important in terms of the number of reported cases. For both forms, the highest incidence occurred in females and children (0–14 years). When analyzed according to the number of cases in each province, Errachidia (8 728 cases) and Azilal (3 523 cases) were the most affected by ZCL and ACL, respectively, while the highest incidence was noted in Zagora (231 cases/100 000 pop-ulation/10 years) and in Chichaoua (97 cases/100 000 population/10 years), for ZCL and ACL, respectively. Maps of incidence repartition were performed to identify the risk area of ZCL and ACL. Conclusions: ZCL and ACL are still major health problems in Morocco. We highlight the spatiotemporal change of cutaneous leishmaniasis incidence through the country during the last ten years and we underline the correlation between ZCL incidence and the percentage of rural population in Morocco.

  17. Experimental model of cutaneous radiation injury in rabbits

    International Nuclear Information System (INIS)

    Purpose: to describe an experimental model of cutaneous radiation injury in rabbits. Methods: on this study eight six-month-old New Zealand male rabbits, with an average weight of 2.5kg were used. They were distributed in four groups (n=2 per group). The control group did not receive radiotherapy and the others received one radiotherapy session of 2000, 3000 and 4500 cGy, respectively. Photographic analysis and histopathological evaluation of the irradiated areas were carried out. Results: after 30 days, the animals from the control group had all their hair grown. In spite of that, the animals from group 2000 cGy had a 60-day alopecia and from group 3000 cGy, a 90-day alopecia. After the 30th day, the 3000cGy group demonstrated 90-day cutaneous radiation injuries, graded 3 and 4. One of the animals from group 4500 cGy died on the 7th day with visceral necrosis. The other from the same group had total skin necrosis. A progressive reduction of glands and blood vessels count and an increase on collagen deposition was observed. Conclusion: The proposed experimental model is reproducible. This study suggests that the dosage 4500cGy is excessive and the 3000 cGy is the most effective for this experimental model of cutaneous radiation injury in rabbits. (author)

  18. Hemorrhagic bullous dermatosis: a rare heparin-induced cutaneous manifestation.

    2016-01-01

    Heparin is one of the most widely prescribed medications. Cutaneous reactions distant to the injection site are rare and under-reported in the literature. We present an elderly man with history of CNS lymphoma who underwent treatment of a deep venous thrombosis with enoxaparin and subsequently developed well demarcated bullous lesions within days of heparin initiation. The exact pathophysiology is not well understood. Hemorrhagic bullous dermatosis is a rare cutaneous reaction that is temporally associated with the initiation of heparin products. The handful of cases thus far suggest that regression of these seemingly benign lesions may or may not be associated with dose reduction or discontinuation of heparin products and typically occur within a few weeks. Elderly age appears to be one potential risk factor for development of these rare asymptomatic lesions. Malignancy may have some contributing factor and differentiation between this rare cutaneous manifestation from heparin products and other dermatological findings in patients with malignancy is key. Because of the asymptomatic and self-limiting nature of hemorrhagic bullous dermatoses in the setting of heparin product use, we presume that the reported incidence does not reflect true clinical practice.

    Full Text Available Skin is an organ that has a primary function of tactile receptivity and reacts to both external and internal emotional stimuli. Dermatological practice certainly embeds a psychosomatic dimension. A relationship between psychological factors and skin diseases has long been hypothesized. AIMS AND OBJECTIVES The aim of present study is to evaluate the prevalence of cutaneous manifestations in patients with psychiatric disorder. MATERIALS AND METHODS Twenty five psychiatric in-patients admitted in the psychiatry ward of a Tertiary Care Hospital were examined for the presence of cutaneous manifestation over a period of 6 months. Appropriate laboratory investigations such as scraping for Acarus, skin biopsy etc. were performed wherever required. The observations were noted. RESULTS The commonest cutaneous manifestations seen in this study were (i Parasitic infestations like scabies (20%, pediculosis capitis (16%, (ii Xerosis (28 %, (iii Prurigo nodularis (4%, (iv Lichen simplex chronicus (4%, (v Venereophobia (4% and (vi Delusion of parasitosis (4%. CONCLUSION A high incidence of parasitic infestations was noted in our study. The healthcare personnel should be sensitized on the significance of such parasitic infestations in institutionalized patients and the importance of early detection and treatment.

    A 68-year-old male plasterer with no history of trauma presented to our clinic in March 2012 with a 16×14-mm ulcer that developed following a crushed small papule on the right anterior chest. In April 2012, the patient was referred to another hospital, where cutaneous cryptococcosis was diagnosed based on discharge culture results. The patient was treated with oral itraconazole at a dose of 150 mg/day for 10 weeks; however, the ulcer remained unchanged and he discontinued the treatment. In May 2014, when he revisited our clinic, the ulcer with crust had grown to 29×13 mm. No regional lymph node swelling was noted. India ink staining showed a yeast-like fungus with a thick, clear capsule. A cream-colored, viscous yeast-like colony was observed on Sabouraud dextrose agar. Genetic testing identified the isolate as Cryptococcus neoformans serotype A. The patient was negative for serum cryptococcal antigen. Neither chest radiography nor computed tomography revealed any abnormalities. The patient had no underlying disease. Oral fluconazole (400 mg/day for 12 weeks) was prescribed, resulting in scar formation. The patient has remained free of relapse for one year to date, since the end of treatment. Localized cutaneous cryptococcosis is not a commonly used disease name overseas. However, 36 cases of this disease have been reported in Japan (since in 1968). We herein report a new case with localized cutaneous cryptococcosis and summarize previously reported cases in Japan. PMID:27581773

    Full Text Available CONTEXT: Anthrax is a very rare disease in Europe and the United States. AIM: A case of cutaneous anthrax of the hand with a wide skin defect is presented and some clinical observations highlighted. CASE REPORT: A 56-year-old male patient with cutaneous anthrax attended our infectious diseases department with a swelling up to the upper arm. An urgent fasciotomy was undertaken with a diagnosis of compartment syndrome. A black eschar had formed on the dorsal surface of the hand. A superficial tangential escharectomy was performed. RESULTS: Viable fibrous tissue, about 4 to 5 mm in thickness over the extensor tendons, was found under the eschar. At the postoperative 2-year follow-up, remarkable healing was observed via skin grafting. CONCLUSIONS: Hand surgeons should be cautious against the compartment syndrome that may accompany cutaneous anthrax of the hand. A consistent viable fibrous tissue can be found below the eschar. The mechanism for the involvement of the hand dorsum needs further concern.

    Herein, we aimed to report a diffuse large B cell lymphoma (DLBCL) case that had extensive cutaneous relapse with no skin involvement previously. A 59-year-old man presented to hospital in April 2014 with fatigue, anorexia, fever, and anemia. Cervical lymph node biopsy revealed CD20+, BCL2+, MUM1+, BCL6+ high grade B lymphoproliferative neoplasm. After FISH investigation, he was diagnosed as DLBCL. He was given 7 cycles of R-CHOP and achieved remission. However, in November 2014, he had emerging skin lesions that cover nearly all of his body. A control PET-CT revealed diffuse cutaneous involvement. CD20+, BCL2+, MUM1+, BCL6+ high grade B cell lymphoma infiltration was detected with skin biopsy. He was diagnosed as relapse lymphoma, so 2 cycles of R-DHAP were given. There was no treatment response; therefore, R-ICE regimen was started. The patient had achieved second complete remission and his skin lesions were completely regressed. The involvement of skin with CD20+ cells after 7 cycles of rituximab therapy favors that there is a rituximab resistant disease which tends to involve the skin. To conclude, DLBCL may relapse extensively with cutaneous involvement and the best treatment option in these patients is salvage chemotherapy followed by autologous peripheral blood stem cell transplantation.

The official form of biopsy was used as a secondary source of collecting information and it was processed using descriptive statistics.Results: the 10,6 % of the biopsies analyzed corresponded with cutaneous melanoma, its frequency prevailed in 2011 and 2010, with a 25,8 % and 19,3 % respectively. It was evident a higher percentage in males (67,7 % and in the age group between 60 and 69 years old, with a 35,4 %. Caucasian patients were the most affected ones, with a 90,3 % and the predominant location was in the lower limbs in 45,1 % of the cases. The prevailing Clark invasion level was IV, evident by the 32,2 % of the sample, and the most frequent histological variety was the malignant nodular melanoma in 19 patients, for a 61,2 %.Conclusions: cutaneous melanoma prevailed in lower extremities in males and it had a belated diagnosis, since there was prevalence of IV Clark invasion level and nodular melanoma as the most frequent histological type.

    The increasingly aged population worldwide means more people are living with chronic diseases, reduced autonomy, and taking various medications. Health professionals should take these into consideration when managing dermatological problems in elderly patients. Accordingly, current research is investigating the dermatological problems associated with the loss of cutaneous function with age. As cell renewal slows, the physical and chemical barrier function declines, cutaneous permeability increases, and the skin becomes increasingly vulnerable to external factors. In geriatric dermatology, the consequences of cutaneous aging lead to xerosis, skin folding, moisture-associated skin damage, and impaired wound healing. These problems pose significant challenges for both the elderly and their carers. Most often, nurses manage skin care in the elderly. However, until recently, little attention has been paid to developing appropriate, evidence-based, skincare protocols. The objective of this paper is to highlight common clinical problems with aging skin and provide some appropriate advice on cosmetic protocols for managing them. A review of the literature from 2004 to 2014 using PubMed was performed by a working group of six European dermatologists with clinical and research experience in dermatology. Basic topical therapy can restore and protect skin barrier function, which relieves problems associated with xerosis, prevents aggravating moisture-associated skin damage, and enhances quality of life. In conclusion, the authors provide physicians with practical recommendations to assist them in implementing basic skin care for the elderly in an integrated care approach. PMID:26929610

    Exposure to chemicals is an unusual causation of cutaneous burns in children. The aim of this study is to look at childhood chemical burns and compare this to adult chemical burns from the same population. A total of 2054 patients were referred to the pediatric burns unit during the study period. This included 24 cutaneous chemical burns, equating to an incidence of 1.1%. Over half of the injuries occurred in the domestic setting. The mean total body surface area (TBSA) affected was 1.9%. When compared to a cohort of adult patients from the same population with cutaneous chemical burns, the TBSA affected was identical (1.9%) but distribution favored the buttock and perineum in children, rather than the distal lower limb in adults. Children presented earlier, had lower rates of surgical intervention and had a shorter length of stay in hospital (p Chemical burns in children are rare, but are becoming more common in our region. It is important to be aware of the characteristic distribution, etiology and need to identify children at risk of child protection issues.

    Full Text Available Epilepsy is one of the most common neurologic disorders in dogs and life-long treatment with antiepileptic drugs (AED is frequently required. Adverse events of antiepileptic drugs targeting the skin are only rarely reported in veterinary medicine and the true incidence and spectrum of cutaneous reactions in epileptic dogs remains unknown. In this study we hypothesized that cutaneous reactions commonly occur in epileptic dogs and are related to AED treatment. A retrospective case review of 185 dogs treated for epilepsy identified 20.0% with simultaneous appearance of dermatologic signs. In a subsequent prospective case investigation (n=137 we identified newly appearing or distinct worsening of skin lesions following initiation of antiepileptic drug therapy in 10.9% of dogs treated for epilepsy (95% CI 6.8- 17.7%. Cutaneous lesions were classified as probably drug-induced in 40.0% of these cases. Patch-testing and intradermal testing was further investigated as potential diagnostic methods to confirm antiepileptic drug hypersensitivity. They were of high specificity but sensitivity and positive predictive value appeared inappropriate to recommend their routine use in clinical practice.

    The reason why the cutaneous form of sarcoidosis is well known in the literature is because of its spectrum of manifestations granting it the fame of a Great Imitator. The mystery shrouding the pathogenesis of this rare cutaneous disease is still there (in spite of the fundamental progress of the various diagnostic methods in current day medicine). The production of the morphological substrate - the epithelioid cell granuloma - which is considered to be characteristic of skin sarcoidosis, could, however, also be the end result of a reaction to i) various specific infectious agents such as Leishmaniasis cutis, coccidioidomycosis, etc., ii) certain residual bacterial or other mycobacterial antigens which, at the moment of setting the diagnosis are - by definition - non-infectious but still immunogenic, as well as iii) different tumor antigens in lesional tissue or other location. Often, differentiating between sarcodiosis and a sarcoid-like reaction, based on the updated criteria for cutaneous sarcoidosis, is problematic to downright impossible. A future characterization of the genetic signature of the two conditions, as well as the implementation of additional mandatory panels for i) the identification of certain infectious or ii) non-infectious but immunogenic and iii) tumor antigens in the epithelioid cell granuloma (or in another location in the organism), could be a considerable contribution to the process of differentiating between the two above-mentioned conditions. This will create conditions for greater accuracy when setting the subsequent therapeutic approaches.

    @@ Lateral femoral cutaneous neuritis, also named as meralgia paresthetica or Roth syndrome, is marked by cutaneous pain or paresthesia such as formication or numbness in one or both thighs, which can be aggravated by prolonged standing or walking; it is also characterized by hypoesthesia or skin sensibility without muscular atrophy or dyskinesia. Forty-three cases of lateral femoral cutaneous neuritis have been treated by pricking and cupping therapy since 1996. Now it was reported as follows.

  11. Pink plaque on the arm of a man after a trip to Mexico: cutaneous leishmaniasis

    OpenAIRE

    Cohen, Jeffrey M.; Saavedra, Arturo P; Sax, Paul E.; Lipworth, Adam D

    2015-01-01

    Cutaneous leishmaniasis is a parasitic infection caused by protozoa of the Leishmania genus that presents as asymptomatic pink papules that may ulcerate. There are several species of Leishmania found in 98 endemic countries and whereas all are associated with cutaneous disease, only specific species can cause mucocutaneous or visceral disease. Although the diagnosis of cutaneous leishmaniasis can be confirmed with Giemsa staining of a biopsy or “touch prep” specimen, only speciation at specia...

    Apart from for cutaneous deep fungal or mycobacterial infections, thermotherapy has been used for various malignant tumors. We report a case of primary cutaneous anaplastic large cell lymphoma, which responded quite well to topical thermotherapy using chemical pocket hand warmers. The treatment resulted in an immediate tumor regression without recurrence. This method is simple and might be a useful tool against solitary cutaneous lymphoma, especially of elderly patients with poor performance status or with various systemic complications.

    2010-01-01

    Full Text Available Background : In India, indigenous cases of cutaneous leishmaniasis (CL are mainly confined to the northwestern region. But now, more and more case reports are coming in from other parts of India. In January 2009, a 26-year-old lady residing in a forest area in Thiruvananthapuram district of Kerala State presented with bluish red nodules on her upper extremities, of six months duration, which was clinically more in favor of cutaneous leishmaniasis. She had never gone out of the district of Thiruvananthapuram in her life. Aim : To investigate whether the patient hails from a new endemic focus of cutaneous leishmaniasis. Setting and Design : An epidemiological investigation in the form of a survey was carried out in March 2009 by a multidisciplinary team among 63 persons residing in the Mele Aamala and Aayiramkala forest tribal settlements in Kuttichal Panchayat of Thiruvananthapuram district. Material and Methods : History taking and clinical examination of 38 persons in the area with special consideration to skin lesions was undertaken. Microbiological and histopathological examination of the skin lesions was done. Breeding places of sand fly and possible reservoirs of Leishmania were also simultaneously investigated. Statistical analysis used : The data obtained was tabulated as frequency and percentage. Chi-square test was done to find out the statistical significance of differences in distributions. Results : Out of the 38 persons examined, active lesions were found in 12 persons and six had healed lesions. Tissue samples were obtained from seven out of the 12 suspected cases. Four of them showed Leishman Donovan (LD bodies in tissue smears. Out of the cultures taken from three patients, one showed promastigote forms in Novy McNeal Nicolle (NNN medium. Histopathological study was done in five patients and two patients had LD bodies, one had epithelioid cell granuloma and the other two had mixed infiltrate with predominantly macrophages. All

  16. A 27-Year-Old Severely Immunosuppressed Female with Misleading Clinical Features of Disseminated Cutaneous Sporotrichosis

    Science.gov (United States)

    Patel, Atiyah; Mudenda, Victor; Lakhi, Shabir; Ngalamika, Owen

    2016-01-01

    Sporotrichosis is a subacute or chronic granulomatous mycosis caused by fungus of the Sporothrix schenckii complex. It is considered to be a rare condition in most parts of the world. It mostly causes cutaneous infection but can also cause multisystemic disease. Unlike most deep cutaneous mycoses which have a primary pulmonary focus, it is usually caused by direct inoculation of the fungus into the skin causing a classical linear, lymphocutaneous nodular eruption. However, atypical presentations of the condition can occur especially in immunosuppressed individuals. We report the case of a severely immunosuppressed female who presented with disseminated cutaneous sporotrichosis which was initially diagnosed and treated as disseminated cutaneous Kaposi's sarcoma.

  17. CUTANEOUS MYXOID CYST ON THE SCLEROTIC FINGER IN A PATIENT WITH DIFFUSE SYSTEMIC SCLEROSIS

    Directory of Open Access Journals (Sweden)

    Taeko Nakamura-Wakatsuki

    2013-10-01

    Full Text Available Skin tumors occurring on the scleroderma fingers are rarely seen. Swollen fingers are hallmarks of systemic sclerosis, and mucin deposition in the lesional skin is a constant feature in systemic sclerosis. Here we describe a case of cutaneous myxoid cyst on the flexor aspect of the sclerotic fingers in a patient with severe diffuse cutaneous systemic sclerosis. Cutaneous myxoid cyst is a relatively common benign tumor; however, cases of cutaneous myxoid cysts developing on the scleroderma fingers have not been reported to date. Mucin deposition in the sclerotic skin may be a predisposing factor in the induction of myxoid cyst on the scleroderma finger in our patient.

    2010-07-01

    Recently, we identified an AP-1-dependent target gene in 12-O-tetradecanoylphorbol-13-acetate (TPA)-treated mouse back skin, which encodes a retroviral-like aspartic proteinase (Taps/Asprv1). Taps expression was detected almost exclusively in stratified epithelia of mouse embryos and adult tissues, and enhanced protein levels were present in several non-neoplastic human skin disorders, implicating a crucial role for differentiation and homeostasis of multilayered epithelia. Here, we generated a mouse model in which Taps transgene expression is under the control of the human ubiquitin C promoter (UBC-Taps). Although no obvious phenotype was observed in normal skin development and homeostasis, these mice showed a significant delay in cutaneous wound closure compared with control animals. Shortly after re-epithelialization, we found an increase in keratinocytes in the stratum granulosum, which express Filaggrin, a late differentiation marker. A hypergranulosum-like phenotype with increased numbers of Filaggrin-positive keratinocytes was also observed in UBC-Taps mice after administration of TPA. In summary, these data show that aberrant Taps expression causes impaired skin regeneration and skin remodeling after cutaneous injury and chemically induced hyperplasia. PMID:20237492

  20. Intradermal administration of ATP does not mitigate tyramine-stimulated vasoconstriction in human skin

    Science.gov (United States)

    Wingo, Jonathan E.; Brothers, R. Matthew; Coso, Juan Del

    2010-01-01

    Cutaneous vasodilation associated with whole-body heat stress occurs via withdrawal of adrenergic vasoconstriction and engagement of cholinergic “active” vasodilation, the latter of which attenuates cutaneous vasoconstrictor responsiveness. However, the precise neurotransmitter(s) responsible for this sympatholytic-like effect remain unknown. In skeletal muscle, ATP inhibits adrenergically mediated vasoconstriction. ATP also may be responsible for attenuating cutaneous vasoconstriction since it is coreleased from cholinergic neurons. The effect of ATP on cutaneous vasoconstrictor responsiveness, however, has not been investigated. Accordingly, this study tested the hypothesis that ATP inhibits adrenergically mediated cutaneous vasoconstriction. To accomplish this objective, four microdialysis probes were inserted in dorsal forearm skin of 11 healthy individuals (mean ± SD; 35 ± 11 years). Local temperature at each site was clamped at 34°C throughout the protocol. Skin blood flow was indexed by laser-Doppler flowmetry and was used to calculate cutaneous vascular conductance (CVC; laser-Doppler-derived flux/mean arterial pressure), which was normalized to peak CVC achieved with sodium nitroprusside infusion combined with local skin heating to ∼42°C. Two membranes were perfused with 30 mM ATP, while the other two membranes were flow matched via administration of 2.8 mM adenosine to serve as control sites. After achieving stable baselines, 1×10−4 M tyramine was administered at all sites, while ATP and adenosine continued to be infused at their respective sites. ATP and adenosine infusion increased CVC from baseline by 35 ± 26% CVCpeak units and by 36 ± 15% CVCpeak units, respectively (P = 0.75). Tyramine decreased CVC similarly (by about one-third) at all sites (P < 0.001 for main effect and P = 0.32 for interaction). These findings indicate that unlike in skeletal muscle, ATP does not attenuate tyramine-stimulated vasoconstriction in human skin. PMID

    Full Text Available Neurofibromatosis type 1 (NF-1 is the most common form of neurofibromatosis. Since the significance of various cutaneous manifestations of NF-1 has not been known in Indian population, hence, the present study was undertaken. A total of 40 patients with NF-1 were identified between August 1998 to June 2000 with a prevalence rate of 20.4 per 10,000 individuals attending our clinic. Male to female ratio was 2.3: 1. The age of the patients ranged from 15 to 70 years with a mean age of 29.57 years. Most patients (18 cases belonged to age group of 21-30 years followed by 11-20 years age group (11 cases. Twenty four cases had onset of disease between 11-20 years of age and ten cases in 21-30 years age group. Thirty one of 40 cases presented with asymptomatic nodules, three sought medical opinion for cosmetic reasons and another three for hyper pigmented patch. Analysis of cutaneous manifestations showed, 39 of 40 cases (97.5% had neurofibromas. Palmar melanotic macules were noted in 36 (90% cases whereas café â€" au-lait macules were seen in 33(82.5% cases. Subsequent, less common findings were intertriginous freckles in 31(77.5% cases, plantar melanotic macules in 18(45% cases and generalized freckles in 4(10% cases. Statistical analysis of cases and controls revealed significant association of NF-1 with neurofibromas, palmar melanotic macules, café-au-lait macules, intertriginous freckles and plantar melanotic macules(p<0.001. This study brings into focus some of the cutaneous manifestations noted in South Indian patients especially palmar and plantar melanotic macules, not highlighted in the western literature.

    Full Text Available Context : An epidemic of chikungunya disease occurred in India during late 2005 through 2006 affecting nearly 1,400,000 people. Aim : To study the cutaneous manifestations in suspected cases of chikungunya disease. Settings and Design : Patients who attended our outpatient departments from January 2006 to September 2006 were prospectively included if they had symptoms of chikungunya disease according to the ′case definition′ of the National Institute of Communicable Diseases, Directorate General of Health Services, Government of India. The criteria were an acute illness characterized by the sudden onset of fever and several symptoms such as joint pain, headache, backache, photophobia, and eruption during an epidemic of chikungunya fever in the absence of confirmatory serological tests. Materials and Methods : A total of 115 patients (65 men and 50 women who satisfied the above criteria were enrolled for the study. Results : An erythematous maculopapular rash subsiding without any sequelae in 3-4 days was the most common cutaneous finding in our patients. Genital ulcers distributed predominantly over the scrotum and base of the penile shaft in men and labia majora in women were the second most common manifestation. Other manifestations included tenderness/edema of hands and feet, grouped hyperpigmented macules over the nose and cheeks, fixed drug eruptions, erythema nodosum, erythema multiformae, generalized urticarial eruptions, and flare up of pre-existing psoriasis and lichen planus. Conclusions : To conclude, a plethora of cutaneous manifestations were noted in suspected cases of chikungunya disease. Genital ulcers, to the best of our knowledge, have not been reported during the earlier epidemics but have been reported by others during the present one.

    Full Text Available Background: Cutaneous leishmaniasis (CL is a parasitic cutaneous infection caused by Leishmania parasite. The histopathology is usually granulomatous in nature. Aims: The aim of the present study is to elucidate the histology of CL and evaluate the presence and the frequency of panniculitis among the affected patients. Settings and Design: Case series interventional study. Materials and Methods: Thirty-five patients with CL were diagnosed clinically between December-2012 and May-2013. Diagnostic confirmation established by smears, culture, and polymerase chain reaction (PCR. The histopathological assessment was carried out to study the general pathology and to look for the presence of panniculitis. Statistical Analysis Used: Simple statistics utilized via SPSS version 16.0 (SPSS, Inc., Chicago, USA. Results: Eighteen women and 17 men with CL were enrolled in the present work with a mean duration of their disease was 3 months. The results of the diagnostic tests were as follow: The smear was positive in 21 (60% of cases, Leishman-Donovan (LD bodies were seen in 7 (20% patients, culture was positive in 24 (68%, and PCR was positive in 32 (91.4% patients. The epidermal changes included acanthosis, pseudoepitheliomatous hyperplasia, ulceration, focal spongiosis, and interface dermatitis while the dermal changes were dependent on the spectrum of the disease, so in the ulcerative lesions there was lymphohistiocytic infiltration with foci of plasma cells and sometimes aggregate of LD bodies, whereas in the dry lesions the pathology is mainly of epithelioid granuloma. Panniculitis was seen in 16 (46% cases as a diffuse lymphohistiocytic infiltration of both the septum and lobules of the subcutaneous layer of the skin. Conclusion: Panniculitis is an important feature of CL that must be differentiated from other diseases that can simulate CL such as chronic skin infections, Discoid lupus erythematosus, and cutaneous lymphoma.

  4. Cutaneous postirradiation sarcoma. Ultrastructural evidence of pluripotential mesenchymal cell derivation

    International Nuclear Information System (INIS)

    A 75-year-old man developed synchronous multicentric cutaneous sarcomas and basal cell carcinoma of the face 57 years after receiving irradiation for acne. During the previous 30 years he had been treated many times for actinic keratoses and basal cell carcinomas. Surgical treatment had included total nasectomy, excision, and replacement of the skin of the upper and lower lips and the chin. Due to the multiplicity of morphologic patterns, it was difficult to subtype the sarcomas. Ultrastructural studies showed histiocyte-like, fibroblast-like and vasoformative cells suggesting an origin from a pluripotential mesenchymal stem cells

    Full Text Available Cutaneous squamous cell carcinoma of the ear represents a high-risk tumor location with an increased risk of metastasis and local tissue invasion. However, it is uncommon for these cancers to invade through nearby cartilage. Cartilage invasion is facilitated by matrix metalloproteases, specifically collagenase 3. We present the unusual case of a 76-year-old man with an auricular squamous cell carcinoma that exhibited full-thickness perforation of the scapha cartilage. Permanent sections through the eroded cartilage confirmed tumor invasion extending to the posterior ear skin.

    1994-01-01

    The development of extensive cutaneous necrosis in a patient with tumour-stage mycosis fungoides is described. Skin biopsies showed a lymphomatous infiltrate, and thrombosis of dermal blood vessels. Investigation revealed the presence of anticardiolipin antibodies, a lupus anticoagulant, and low free protein S, which contributed to a prothrombotic state. Antiphospholipid antibodies have been detected in non-Hodgkin's lymphoma, but clinical manifestations are uncommon. Such autoantibodies may be produced by neoplastic lymphoid cells. The frequency with which antiphospholipid antibodies occur in mycosis fungoides is currently unknown.

    Expression of the lymphocyte homing receptor CD44 and its splice variants have been linked to tumour dissemination and poor prognosis in non-Hodgkin's lymphoma. Specifically, the in vitro expression of variant exon V6 confers metastatic potential in rat pancreatic carcinoma cell lines. In this study, we investigated the expression of CD44 splice variants in cutaneous T-cell lymphomas, including patients with mycosis fungoides (MF), Sezary syndrome (SS), large-cell anaplastic lymphoma (LCAL) and HTLV1-associated cutaneous lymphoma. In addition, 4 involved lymph nodes from 2 patients with MF and 1 patient with SS were examined. Inflammatory dermatoses, lichen planus and psoriasis, and normal skin were also studied. Immunohistochemistry was performed using a panel of monoclonal antibodies, including those with specificity for CD44H (standard isoform) and variant exons V3, V6 and V8-9. Normal epidermal keratinocytes were consistently CD44H and CD44 V3, V6 and V8-9 positive. In all the different clinicopathological subtypes and stages of cutaneous T-cell lymphomas, including involved lymph nodes, tumour cells consistently expressed CD44H, but were CD44 V3 and V6 negative. CD44 V8-9 was expressed on a majority of tumour cells in 2/5 LCAL and on occasional tumour cells in 2/5 LCAL. Occasional V8-9 positive tumour cells were also identified in 6/13 MF, 1/4 SS and 3/4 HTLV1. In 2/3 lymph node samples from 2 patients with tumour-stage MF, CD44 V8-9 expression was found on a small percentage of atypical mononuclear cells. Scattered V8-9 positive dermal mononuclear cells were present in sections of lichen planus and psoriasis. We have found no evidence to suggest that the metastasis-associated CD44 variant exon (V6) is expressed in cutaneous T-cell lymphoma, or that CD44H expression is associated with an adverse prognostic group. It is not clear whether the strong expression of CD44 V8-9 in 2 patients with CD30 positive LCAL reflects activation status or metastatic potential.

    Early stage mycosis fungoides represents the most common clinical presentation of cutaneous lymphoma, with skin-directed therapies long established in its treatment. These therapies continue to change as new treatment regimens emerge. Other skin-directed treatments include light and radiation therapy. Therapies with higher levels of evidence and less systemic toxicity are usually preferred as first-line treatment. However, even these established therapies, like topical corticosteroids and carmustine, lack randomized clinical trials to establish their efficacy. Research is also needed to further define the role of combination topical therapies and how skin-directed therapies can be used as adjuvants to systemic medications. PMID:26433841

    2014-01-01

    Full Text Available Coccidioidomycosis is a fungal disease found only in the Western Hemisphere. In recent years, the incidence of the disease has increased in California and Arizona, which may be partially due to the rapid immigration of previously unexposed persons from states outside the endemic areas. The disease in the nonendemic areas is usually imported. Determining a history of exposure is critical for performing the diagnosis of coccidioidomycosis in these cases. Histopathological examination is the key to the diagnosis when fungal culture and molecular studies are not available. We hereby report an imported case of cutaneous coccidioidomycosis, which to the best of our knowledge is the first case report from North India.

    Cutaneous Leishmaniasis (CL) remains a major world health problem, with about 1.5 million new cases each year. Caused by protozoa Leishmania, in South America, this infection can vary from a chronic skin ulcer, to an erosive mucosal disease and severe facial disfigurement. Pentavalent antimony (Sb{sup +5}) as sodium stibogluconate (Pentostam) or meglumine antimoniate (Glucantime) are main drugs for treating most forms of human leishmaniasis. For six decades, despite the recent developments, the effective therapy to cutaneous leishmaniasis has been based on long parenteral courses of such drugs, even though these are fairly costly, toxic and inconvenient to use, without adequate knowledge on their pharmacokinetics or mechanism of action. Pharmacokinetics studies could be based on bioactive traceable drugs, usually with radioactive isotopes, but antimony radioisotopes are unavailable commercially. Neutron irradiation is a powerful tool in the analysis of mineral content of samples, for antimony, there are at least two main isotopes that could be formed after neutron irradiation in nuclear reactor. The aim of the present study was to construct antimony salts with those radioisotopes to obtain tracers to compare the pharmacokinetic and the tissue distribution of neutron irradiated meglumine antimoniate in healthy and cutaneous leishmaniasis experimentally infected mice. Meglumine antimoniate, (Glucantime, Aventis, S.P, Brazil), was neutron irradiated inside the IEA-R1 nuclear reactor (IPEN/CNEN-SP), producing two radioisotopes {sup 122}Sb and {sup 124}Sb. Its biodistribution was verified in BALB/c mice experimentally infected with Leishmania (Leishmania) Amazonensis, which received a single intraperitoneal dose of the drug. At different times after injection, the tissues and blood were excised and activity measured in a NaI (Tl) scintillation counter. Compared with the healthy mice, experimentally infected mice had significantly lower maximum concentration of antimony

    Mantle cell lymphoma (MCL) commonly involves extranodal sites, usually as a manifestation of disseminated disease. In rare cases, MCLs may arise as a primary tumor in the skin. Blastoid mantle cell lymphoma (BV-MCL) is a rare variant and has a more aggressive clinical course. The phenotype of BV-MCL is characterized as CD20+, CD5+, cyclin D1+, CD23-, and CD10-. Interphase fluorescence in situ hybridization shows a characteristic t(11;14) fusion pattern. We report a case of a BV-MCL arising in skin as primary cutaneous MCL with the characteristic immunophenotype and translocation.

    Full Text Available The basal cell carcinoma is the most common skin tumour especially affecting the white individuals worldwide. The exact incidence of basal cell carcinoma is not known from India but non melanoma skin cancers comprises about 1-2% of cutaneous tumour in India. The most common skin tumour is squamous cell carcinoma in albinism and the incidence of basal cell carcinoma is less. Hereby, we report a peculiar case of basal cell carcinoma in albinism to highlights the importance of early recognition and diagnosis of suspected lesions by performing histopathological examination in unusual circumstances.

    Full Text Available Cutaneous T-cell lymphomas (CTCLs comprise a heterogeneous group of lymphoproliferative disorders characterized by the proliferation of skin-homing post-thymic T-cells. It is the second most common extranodal non-Hodgekin′s lymphoma. Many variants of mycosis fungoides and CTCLs are known to date, differing in clinical, histological, and immunophenotypic characteristics. Oral involvement has also been reported rarely in CTCLs. Treatment depends on the disease stage or the type of variant. New insights into the disease and the number of emerging novel therapeutic options have made it an interesting area for dermatologists and medical oncologists.

    Cutaneous larva migrans (CLM) represents the most common tropically acquired dermatosis. CLM is caused by infection with hookworm larvae in tropical and sub-tropical areas, and people who have a history of foreign travel and of walking barefoot on sandy soil or beaches are at a high risk of getting infected with it. The diagnosis is usually made on the basis of the typical appearance of the lesion, intense itching and history of foreign travel. CLM is a common parasitic skin disease that can be easily prevented by wearing 'protective' footwear. A case of CLM is described in this article.

    Epithelial tumorigenesis has been linked to AKT up-regulation. Human papillomaviruses (HPV) cause anogenital cancers and anogenital HPV infection up-regulates AKT activity. Mounting evidence points to a role for cutaneous HPVs as etiologic factors in skin tumorigenesis. High-risk cutaneous β HPVs have been linked to carcinogenesis in immunosuppressed patients, and high-risk cutaneous HPV8 genes enhance tumorigenesis in transgenic mice. We find that, in contrast to anogenital HPVs, cutaneous H...

    2016-06-01

    Full Text Available ABSTRACT: Surgical excision of neoplasms usually requires a large incision with safety margin, resulting in large cutaneous defects. Skin flaps permit closure of extensive cutaneous defects that would not be closed directly. The rhomboid cutaneous flap can be used in places of the body where a rhomboid defect with internal angles of 60 and 120 degrees can be made. The aim of this paper is to report the her use for reconstruction of the defect created after resection of a tumor on dogs' face . Total removal of the tumor and a safety margin was performed, and then the surgical defect was reconstructed with a rhomboid cutaneous flap. The final result was satisfactory, with an esthetically and functional acceptable scar, a without deformities to the oral commissure or eye. The cutaneous flap was considered a viable alternative for reconstruction of large surgical defects, of relatively simple execution and good functional and cosmetic results.

    Adenomyoepithelioma (AME) is a biphasic neoplasm of epithelial and myoepithelial cells. It is most commonly found in the breast, although rare cases have been reported from the lung, salivary glands, and skin. There are 5 well-documented cases of cutaneous AME in the literature. We report a new case of cutaneous AME. Our case was commingled with apocrine hidrocystoma. This is the first report of cutaneous AME in a male patient and the first to describe SOX10 immunostaining in cutaneous AME. We review the literature on cutaneous AME and note the greater than chance colocalization with other adnexal tumors. We speculate that AME may represent localized overgrowth of myoepithelial cells within a pre-existent sweat gland tumor. Histopathologists should be aware of the potential of SOX10-positive myoepithelial neoplasms to mimic nodular melanocytic proliferations. PMID:26981739

    Full Text Available Cutaneous leishmaniasis is a disease endemic to Central and South America, Mexico and the Caribbean, and affects millions of people. As travel to these regions becomes more common, cutaneous leishmaniasis is becoming a disease of increasing importance in the developed world. However, disease recognition and access to appropriate therapy for cutaneous leishmaniasis remains a challenge in North America. The present article reports a case of cutaneous leishmaniasis in a Canadian man following a trip to Costa Rica. Species-specific diagnosis was confirmed by polymerase chain reaction analysis of a skin biopsy, which was positive for Leishmania panamensis. After failing a course of itraconazole, the patient was successfully treated with sodium stibogluconate, despite significant barriers to administering this therapy, and the paucity of data regarding its efficacy and tolerability. The pathophysiology, diagnosis and systemic treatment of cutaneous leishmaniasis, as well as its emerging presence in the developed world, are reviewed.

    A cutaneous horn is a rare clinical condition characterised by a conical projection of hyperkeratotic epidermis. Cutaneous horns most commonly arise from sun-exposed skin in elderly men, but may arise from any part of the body at any age in men and women. When a cutaneous horn forms, it is important to determine the underlying cause. Various skin diseases may present with cutaneous horns including viral warts, actinic keratosis, keratoacanthoma, seborrhoeic keratosis, pyogenic granuloma, discoid lupus erythematosus, verruca vulgaris, Bowen's disease, basal cell carcinoma and squamous cell carcinoma. The underlying pathology is benign in 61.1% of cases, premalignant in 23.2% of cases and malignant in 15.7% of cases. We report a patient with a cutaneous horn arising from an area of discoid lupus erythematosus on the scalp.

    2015-06-01

    Cutaneous leishmaniasis is a parasitic infection caused by protozoa of the Leishmania genus that presents as asymptomatic pink papules that may ulcerate. There are several species of Leishmania found in 98 endemic countries and whereas all are associated with cutaneous disease, only specific species can cause mucocutaneous or visceral disease. Although the diagnosis of cutaneous leishmaniasis can be confirmed with Giemsa staining of a biopsy or "touch prep" specimen, only speciation at specialized centers such as the Centers for Disease Control (CDC) can determine the risk of mucocutaneous or visceral disease. Treatment of cutaneous leishmaniasis is varied and depends on the extent of cutaneous disease and the risk of mucocutaneous or visceral disease. PMID:26158361

    Full Text Available We report our experience with the diagnosis and treatment of 60 patients with American cutaneous leishmaniasis. They were infected in Panama (55, Brazil (4 or Colombia (I. Among 35 patients with a 3 week exposure in Panama, the mean maximum incubation period was 33 days (range 4-81 days. Diagnosis was delayed an average of 93 days after onset of skin lesions, due to the patient's delay in seeking medical attention (31 days, medical personnel's delay in considering the diagnosis (45 days, and the laboratory's delay in confirming the diagnosis (17 days. Forty-four patients (73% developed ulcers typical of cutaneous leishmaniasis. Sixteen additional patients (27% had atypical macular, papular, squamous, verrucous or acneiform skin lesions that were diagnosed only because leishmanial cultures were obtained. Of the 59 patients treated with pentavalent antimonial drugs, only 34 (58% were cured after the first course of treatment. Lesions which were at least 2 cm in diameter, ulcerated, or caused by Leishmania braziliensis were less likely to be cured after a single course of treatment than were lesions smaller than 2 cm, nonulcerated or caused by Leishmania mexicana or Leishmania donovani.

  20. Metastatic Tumor Dormancy in Cutaneous Melanoma: Does Surgery Induce Escape?

    Directory of Open Access Journals (Sweden)

    William W. Tseng

    2011-02-01

    Full Text Available According to the concept of tumor dormancy, tumor cells may exist as single cells or microscopic clusters of cells that are clinically undetectable, but remain viable and have the potential for malignant outgrowth. At metastatic sites, escape from tumor dormancy under more favorable local microenvironmental conditions or through other, yet undefined stimuli, may account for distant recurrence after supposed “cure” following surgical treatment of the primary tumor. The vast majority of evidence to date in support of the concept of tumor dormancy originates from animal studies; however, extensive epidemiologic data from breast cancer strongly suggests that this process does occur in human disease. In this review, we aim to demonstrate that metastatic tumor dormancy does exist in cutaneous melanoma based on evidence from mouse models and clinical observations of late recurrence and occult transmission by organ transplantation. Experimental data underscores the critical role of impaired angiogenesis and immune regulation as major mechanisms for maintenance of tumor dormancy. Finally, we examine evidence for the role of surgery in promoting escape from tumor dormancy at metastatic sites in cutaneous melanoma.

  1. Effective and lesion-free cutaneous influenza vaccination.

    Wang, Ji; Li, Bo; Wu, Mei X

    2015-04-21

    The current study details efficient lesion-free cutaneous vaccination via vaccine delivery into an array of micropores in the skin, instead of bolus injection at a single site. Such delivery effectively segregated vaccine-induced inflammation, resulting in rapid resolution of the inflammation, provided that distances between any two micropores were sufficient. When the inoculation site was treated by FDA-approved nonablative fractional laser (NAFL) before insertion of a PR8 model influenza vaccine-packaged, biodegradable microneedle array (MNs), mice displayed vigorous antigen-uptake, eliciting strong Th1-biased immunity. These animals were completely protected from homologous viral challenges, and fully or partially protected from heterologous H1N1 and H3N2 viral challenges, whereas mice receiving MNs alone suffered from severe illnesses or died of similar viral challenges. NAFL-mediated adjuvanicity was ascribed primarily to dsDNA and other "danger" signals released from laser-damaged skin cells. Thus, mice deficient in dsDNA-sensing pathway, but not Toll like receptor (TLR) or inflammasome pathways, showed poor responses to NAFL. Importantly, with this novel approach both mice and swine exhibited strong protective immunity without incurring any appreciable skin irritation, in sharp contrast to the overt skin irritation caused by intradermal injections. The effective lesion-free cutaneous vaccination merits further clinical studies. PMID:25848020

    It is currently difficult for the amputee to perceive environmental information such as tactile pressure on the fingertip of the present upper limb prostheses. Sensory feedback induced by cutaneous electrical stimulation can be used to transmit tactile information from hand prostheses to sensory nerve of intact upper arm, thus producing the corresponding perceptions in human brain. In order to have a deeper understanding on the distribution of stimulation current within the limb, and find a better placement of the stimulating and reference electrodes, we constructed a three-dimensional upper-limb model to systematically study the effect of electrode placement on current distribution based on finite element analysis. In these simulations, the reference electrode is positioned at four different locations around and on the axial direction of the arm. The results show that with the increase of distance between reference electrode and stimulating electrode, the current density increases in the skin layer of the upper limb. When the reference electrode is on the opposite side of stimulating electrode around the arm, the current is more concentrated in the skin layer, which is in line with recent findings in psychophysiological experiments. But better spatial selectivity could be achieved when the reference electrode is closer to the stimulating electrode around the arm, and it is more obvious in comparison with that on the axial direction. These findings will provide insights for the design of electrode array used for evoking cutaneous sensory afferents.

    2015-01-01

    Primary cutaneous T-cell lymphomas are a group of rare hematologic malignancies, derived from mature T lymphocytes and initially developing only in the skin. The most common lymphomas representing this group are mycosis fungoides and Sezary syndrome. Mycosis fungoides is an indolent disease with a chronic course and characteristic evolution of the skin lesions from erythematous patches, through plaques to tumors. Sezary syndrome is characterized by an aggressive course and a triad of symptoms (erythroderma, generalized lymphadenopathy, and the presence of atypical cells in the skin, lymph nodes and peripheral blood). The etiopathogenesis of cutaneous lymphomas is not fully understood, but a few studies on angiogenesis and lymphangiogenesis in these malignancies indicate a significant role in their development and progression. Angiogenesis is a process of formation of new blood vessels from existing ones. Lymphangiogenesis is a similar process concerning lymphatic vasculature. Development of new vessels is a complex process composed of several successive stages: migration, proliferation, and differentiation of endothelial cells, extracellular matrix degradation and formation and stabilization of new vessels, regulated by growth factors, cytokines and other proteins. Both phenomena are essential in the development and progression of solid tumors and hematological malignancies. Therapeutic strategies involving the inhibition of tumor angiogenesis and lymphangiogenesis are a promising new direction of studies in antitumor therapy, requiring further experiments.

    In this study, we aimed to use both the probability-based and the frequency-based analyses methods simultaneously to examine cutaneous silent period (CSP) induced by strong electrical currents. Subjects were asked to contract their first dorsal interosseus muscles so that one motor unit monitored via intramuscular wire electrodes discharged at a rate of approximately 8 Hz. Strong electrical stimuli were delivered to the back of the hand that created a subjective discomfort level of between 4 and 7 [0-10 visual analogue scale] and induced cutaneous silent period in all units. It was found that the duration of the CSP was significantly longer when the same data were analysed using frequency-based analysis method compared with the probability-based methods. Frequency-based analysis indicated that the strong electrical stimuli induce longer lasting inhibitory currents than what was indicated using the probability-based analyses such as surface electromyogram and peristimulus time histogram. Usage of frequency-based analysis for bringing out the synaptic activity underlying CSP seems essential as its characteristics have been subject to a large number of studies in experimental and clinical settings.

    Lupus erythematosus (LE) is a multifactorial autoimmune disease with clinical manifestations of differing severity which may present with skin manifestations as primary sign of the disease (cutaneous lupus erythematosus, CLE) or as part of a disease spectrum (systemic lupus erythematosus, SLE). To date, no drugs are approved specifically for the treatment of CLE and only single agents have been applied in randomized controlled trials. Therefore, topical and systemic agents are used "off-label", primarily based on open-label studies, case series, retrospective analyses, and expert opinions. In contrast, several agents, such as hydroxychloroquine, chloroquine, cyclophosphamide, azathioprine, and belimumab, are approved for the treatment of SLE. Recent approaches in the understanding of the molecular pathogenesis of LE enabled the development of further new agents, which target molecules such as interleukin 6 (IL-6) and interferon (IFN). Only single trials, however, applied these new agents in patients with cutaneous involvement of the disease and/or included endpoints which evaluated the efficacy of these agents on skin manifestations. This article provides an updated review on new and recent approaches in the treatment of CLE.

    Full Text Available Toxic epidermal necrolysis (TEN is a rare but serious is a rare but potentially life-threatening condition. It is primarily a cutaneous reaction to various precipitating agents, characterized by wide spread erythema and detachment of the epidermis from the dermis. Among the various cutaneous adverse drug reactions, TEN occupy a primary place in terms of mortality. In TEN large sheets of skin are lost from the body surface, thereby decreasing the protecting function of the skin, which results in complications. Usually, TEN is self-limited in absence of complications. If complicated by sepsis, there will be increased chances of mortality. The main treatment would be cessation of the causative drug and early admission of the patient for supportive care and minimizing the occurrence of complications. The present articles reviews the etiology, pathophysiology, differential diagnosis and treatment protocol, with a case of TEN occurrence in a child of 4 years age after consuming phenytoin syrup for febrile convulsions.

    Wound healing is a complex homeostatic response to injury that engages numerous cellular activities, processes, and cell-to-cell interactions. The complement system, an intricate network of proteins with important roles in immune surveillance and homeostasis, has been implicated in many physiological processes; however, its role in wound healing remains largely unexplored. In this study, we employ a murine model of excisional cutaneous wound healing and show that C3(-/-) mice exhibit accelerated early stages of wound healing. Reconstitution of C3(-/-) mice with serum from C3(+/+) mice or purified human C3 abrogated the accelerated wound-healing phenotype. Wound histology of C3(-/-) mice revealed a reduction in inflammatory infiltrate compared with C3(+/+) mice. C3 deficiency also resulted in increased accumulation of mast cells and advanced angiogenesis. We further show that mice deficient in the downstream complement effector C5 exhibit a similar wound-healing phenotype, which is recapitulated in C5aR1(-/-) mice, but not C3aR(-/-) or C5aR2(-/-) mice. Taken together, these data suggest that C5a signaling through C5aR may in part play a pivotal role in recruitment and activation of inflammatory cells to the wound environment, which in turn could delay the early stages of cutaneous wound healing. These findings also suggest a previously underappreciated role for complement in wound healing, and may have therapeutic implications for conditions of delayed wound healing.

Case Report: A 41 year old male was evaluated for hair loss, in patches on the scalp. We studied selected adaptor proteins expressed in T, natural killer, neutrophil and mast cells; these proteins are important mediators for antigen receptor signaling in situ. Methods: Skin biopsies for hematoxylin and eosin examination, as well as for direct immunofluorescence and immunohistochemistry analysis were performed. Results: Hematoxylin and eosin staining demonstrated classic features of lupus with focal dermal scarring; epidermal atrophy was noted, with lymphohistiocytic infiltrates around the skin appendages. Direct immunofluoresence revealed classic, lupus band positive staining along the dermal/epidermal junction. In addition, immune reactants were identified in neurovascular areas, and around pilosebaceous units. Immunohistochemistry staining showed positive staining for the T-cell antigen receptor zeta chain, the linker for activation of T cells, myeloperoxidase, cyclo-oxygenase 2, melanoma-associated antigen 1, B cell leukemia/lymphoma-2 associated X protein, and BCL-2 markers. The positive staining was observed within the dermal inflammatory infiltrate, around pilosebaceous units, upper dermal blood vessels, and focally within eccrine sweat glands. Conclusions: The pathobiology of cutaneous lupus involves not only the epidermis, but also dermal pilosebaceous units, eccrine sweat glands and blood vessels. Further studies are recommended, especially in the light of presented data regarding T cell activation and proapototic molecules.

  11. Imaging Cutaneous T-Cell Lymphoma with Optical Coherence Tomography

    2012-07-01

    Full Text Available Aim: To investigate the presentation of a patch-stage cutaneous T-cell lymphoma (CTCL using optical coherence tomography (OCT. Methods: A patient with a patch caused by CTCL was photographed digitally, OCT-scanned and biopsied. A normal skin area adjacent to the patch was OCT-scanned for comparison, but not biopsied. The OCT image and the histological image were compared. Results: The OCT images illustrated a thickened and hyperreflective stratum corneum. OCT also demonstrated several elongated hyporeflective structures in the dermis. The largest structure was measured to have a width of 0.13 mm. A good immediate correlation was found between histology and OCT imaging of the sample. Conclusion: The aetiology of the elongated structures is thought to be lymphomatous infiltrates. Similar findings have been described in ocular lymphoma and may therefore be an important characteristic of cutaneous lymphoma. It may further be speculated that the differences in OCT images may reflect the biological behaviour of the infiltrate. This observation therefore suggests that OCT imaging may be a relevant tool for the in vivo investigation of mycosis fungoides and other CTCLs, but in order to verify these observed patterns in OCT imaging, further investigations will be required.

    Full Text Available We present a case of an 18-year-old male patient who, after two years of inappropriate treatment for cutaneous leishmaniasis, began to show nodules arising at the edges of the former healing scar. He was immune competent and denied any trauma. The diagnosis of recurrent cutaneous leishmaniasis was made following positive culture of aspirate samples. The patient was treated with N-methylglucamine associated with pentoxifylline for 30 days. Similar cases require special attention mainly because of the challenges imposed by treatment.Paciente do sexo masculino, 18 anos. Dois anos após tratamento insuficiente para leishmaniose tegumentar americana, apresentou, na mesma localização, lesão formada por cicatriz atrófica central e nódulos verrucosos na periferia.

    2014-08-01

    A 71-year-old woman presented with five scalp nodules that were clinically suspicious for pilar cysts. Histopathologic examination showed a proliferation of mitotically active pleomorphic spindle cells arranged into intersecting fascicles in the dermis and subcutis. Tumor cells displayed deeply eosinophilic cytoplasm and expressed desmin but were negative for S100 protein by immunohistochemistry. Before 10 years, the patient was diagnosed with high-grade retroperitoneal leiomyosarcoma and underwent resection with intraoperative radiation. Metastatic disease involving the lungs, liver and soft tissue developed, requiring treatment with resections, radiation and chemotherapy. Owing to the presentation of multiple scalp nodules with microscopic features of leiomyosarcoma in conjunction with the clinical history of retroperitoneal leiomyosarcoma, a diagnosis of metastatic leiomyosarcoma was made. Scalp metastasis from retroperitoneal leiomyosarcoma is extremely rare and portends a poor prognosis. To our knowledge, only two other cases have been reported in the English literature, and a further search discovered only nine additional cases of scalp metastasis from soft tissue leiomyosarcoma of any non-gynecologic anatomic site. This case highlights the striking microscopic similarity between primary cutaneous and metastatic leiomyosarcoma and illustrates the necessity of adequate clinical information and an appropriate index of suspicion in excluding the possibility of cutaneous metastases of leiomyosarcoma from somatic soft tissue.

  14. Adverse cutaneous reactions induced by exposure to woods

    2013-02-01

    Full Text Available Various adverse cutaneous reactions may occur as a result of exposure to wood dust or solid woods. These include allergic contact dermatitis, irritant contact dermatitis and, more rarely, contact urticaria, photoallergic and phototoxic reactions. Also cases of erythema multiforme-like reactions have been reported. Contact dermatitis, both allergic and irritant, is most frequently provoked by exotic woods, e.g. wood of the Dalbergia spp., Machaerium scleroxylon or Tectona grandis. Cutaneous reactions are usually associated with manual or machine woodworking, in occupational setting or as a hobby. As a result of exposure to wood dust, airborne contact dermatitis is often diagnosed. Cases of allergic contact dermatitis due to solid woods of finished articles as jewelry or musical instruments have also been reported. The aim of the paper is to present various adverse skin reactions related to exposure to woods, their causal factors and sources of exposure, based on the review of literature.

    2013-03-01

    Full Text Available Introduction: Little is known about the incidence and causes of heparin-induced skin lesions. The most commonly reported causes are delayed-type hypersensitivity reactions. We describe 3 patients who were referred to our staff between March and October 2009 for suspected heparin allergies. All were scheduled to undergo major surgery (cardiovascular or orthopedic. Materials and methods: All 3 patients reported the development of itchy, erythematous rashes a few days after the subcutaneous administration of heparin (nadroparin calcium in cases 1 and 2, unspecified in case 3. Each of them underwent a diagnostic work-up for heparin allergy, which included prick and intradermal tests with commonly used heparins and patch testing with undiluted heparins and disinfectants. Results: Patch tests with disinfectants were negative in all 3 cases. In case 2, all allergological tests were negative. In cases 1 and 3, delayed positivity emerged for nadroparin calcium and at least one other heparin tested. Intravenous and/or subcutaneous provocation testing was done with an alternative heparin which produced negative results in skin tests (heparin sodium in case 1, pentasaccharide fondaparinux in case 3. In both cases the alternative drug was tolerated. After our evaluation, all 3 patients underwent surgery with no heparin-related complications. Discussion: The presenting clinical features in these 3 cases provided no information on which reactions were likely to be allergic: all 3 patients presented with similar local delayed reaction. The allergic reactions were identified only after cutaneous testing.

  16. Role for Lyt-2+ T cells in resistance to cutaneous leishmaniasis in immunized mice

    The role of Lyt-2+ T cells in immunologic resistance to cutaneous leishmaniasis was analyzed by comparing infection patterns in resistant C57BL/6 mice and susceptible BALB/c mice induced to heal their infections after sub-lethal irradiation or i.v. immunization, with similar mice treated in vivo with anti-Lyt-2 antibodies. Administration of anti-Lyt-2 mAb resulted in a dramatic reduction in the number of lymphoid cells expressing the Lyt-2+ phenotype. Such treatment led to enhanced disease in both resistant C57BL/6 and irradiated BALB/c mice, as assessed by lesion size, but did not affect the capacity of these mice to ultimately resolve their infections. In contrast, anti-Lyt-2 treatment totally blocked the induction of resistance in i.v. immunized mice. These results suggest, that Lyt-2+ T cells may play a role in immunity to a Leishmania major infection and that their relative importance to resistance may depend on how resistance is induced.

    Full Text Available Diabetes is a common cause of delayed wound healing. The aim of the study was to determine the effect of topical administration of tocopherol cream on the wound healing process in diabetic rats. The study was conducted using 18 male Sprague Dawley rats which were divided into three groups: (I diabetic rats receiving control cream , (II diabetic rats receiving 0.06% tocopherol cream , and (III diabetic rats receiving 0.29% tocopherol cream . Four cutaneous wounds were created at the dorsal region of the rats. Wound healing was assessed by total protein content, rate of wound closure estimation, and histological studies on the tenth day after wounding. Tocopherol treatment enhanced the wound healing process by increasing rate of wound closure and total protein content significantly compared to the control group. Histological observation also showed better organized epithelium and more collagen fibers in the tocopherol treated groups. Application of tocopherol cream enhances wound healing process in diabetic condition which is known to cause delay in wound healing.

    2015-11-01

    An intralymphatic variant of the cutaneous CD30 lymphoproliferative disorders (cutaneous anaplastic large cell lymphoma [ALCL] and lymphomatoid papulosis [LyP]) has been described recently. We retrieved 60 cases of ALCL of the skin (primary cutaneous: 37; cases with concomitant involvement of 1 regional lymph node: 4; skin involvement from systemic disease: 4; cases with staging results unknown: 15) and 16 cases of LyP, to evaluate the presence of lymphatic vessel involvement by neoplastic cells. A D2-40 immunohistochemical staining was used to highlight lymphatic vessels. Lymphatic vessel involvement was found in 36 cases (60%) of ALCL (primary cutaneous: 24; concomitant: 3; secondary cutaneous: 4; staging unknown: 5), and in 6 cases (37.5%) of LyP. Follow-up data, available in 28 patients with ALCL and 11 with LyP, suggested that lymphatic vessel involvement had no negative prognostic implication. Our study demonstrates that cutaneous CD30 lymphoproliferative disorders are frequently characterized by involvement of the lymphatic vessels. The intralymphatic variant of ALCL and LyP may be explained, at least in part, by a particular lymphotropism of the neoplastic cells of cutaneous CD30 lymphoproliferative disorders.

    We report the association of a cutaneous lesion with multiple endocrine neoplasia type 2A (MEN 2A) in three patients from a French family. These lesions are very similar to those previously described in an Italian and an American MEN 2A family and called cutaneous lichen amyloidosis. In all three families the patients presented with a pruritic and pigmented cutaneous lesion localized unilaterally on the upper back. However, in the French family the patients also complained of paroxysmal pain in the same area, in which we could elicit a touch hypoesthesia and pain hyperesthesia. Such an association of cutaneous and neurological features in the upper back is known as Notalgia Paresthetica (NP). NP is believed to represent a neuropathy of the posterior dorsal nerve rami. Unlike the two previously reported families, the histological, immunohistochemical and ultrastructural analysis of the skin biopsies of the French patients did not show any amyloid material. This suggests that the presence of amyloid may not be a constant feature of the cutaneous lesions associated with MEN 2A. We consider these lesions as a form of dorsal neuropathy rather than a cutaneous lichen amyloidosis. Whatever their origin, these cutaneous lesion usually precede the appearance of the neoplastic lesions of MEN 2A. They may act as an early clinical marker that must be searched for in each subject at risk for MEN 2A. In addition, all patients presenting with NP should be screened for MEN 2A. PMID:1348355

  5. Simultaneous disruption of mouse ASIC1a, ASIC2 and ASIC3 genes enhances cutaneous mechanosensitivity.

    Directory of Open Access Journals (Sweden)

    Sinyoung Kang

    Full Text Available Three observations have suggested that acid-sensing ion channels (ASICs might be mammalian cutaneous mechanoreceptors; they are structurally related to Caenorhabditis elegans mechanoreceptors, they are localized in specialized cutaneous mechanosensory structures, and mechanical displacement generates an ASIC-dependent depolarization in some neurons. However, previous studies of mice bearing a single disrupted ASIC gene showed only subtle or no alterations in cutaneous mechanosensitivity. Because functional redundancy of ASIC subunits might explain limited phenotypic alterations, we hypothesized that disrupting multiple ASIC genes would markedly impair cutaneous mechanosensation. We found the opposite. In behavioral studies, mice with simultaneous disruptions of ASIC1a, -2 and -3 genes (triple-knockouts, TKOs showed increased paw withdrawal frequencies when mechanically stimulated with von Frey filaments. Moreover, in single-fiber nerve recordings of cutaneous afferents, mechanical stimulation generated enhanced activity in A-mechanonociceptors of ASIC TKOs compared to wild-type mice. Responses of all other fiber types did not differ between the two genotypes. These data indicate that ASIC subunits influence cutaneous mechanosensitivity. However, it is unlikely that ASICs directly transduce mechanical stimuli. We speculate that physical and/or functional association of ASICs with other components of the mechanosensory transduction apparatus contributes to normal cutaneous mechanosensation.

Health professionals should take these into consideration when managing dermatological problems in elderly patients. Accordingly, current research is investigating the dermatological problems associated with the loss of cutaneous function with age. As cell renewal slows, the physical and chemical barrier function declines, cutaneous permeability increases, and the skin becomes increasingly vulnerable to external factors. In geriatric dermatology, the consequences of cutaneous aging lead to xerosis, skin folding, moisture-associated skin damage, and impaired wound healing. These problems pose significant challenges for both the elderly and their carers. Most often, nurses manage skin care in the elderly. However, until recently, little attention has been paid to developing appropriate, evidence-based, skincare protocols. The objective of this paper is to highlight common clinical problems with aging skin and provide some appropriate advice on cosmetic protocols for managing them. A review of the

    Three young women recently returned to the metropolitan Detroit area with cutaneous larva migrans. All three had vacationed at a popular club resort on the Caribbean island of Martinique. Cutaneous larva migrans is frequently seen in the southern United States, Central and South America, and other subtropical areas but rarely in northern climates. Several organisms can cause cutaneous larva migrans, or creeping eruption. The larvae of the nematode Ancylostoma braziliense are most often the causative organisms. Travel habits of Americans make it necessary for practitioners in northern climates to be familiar with diseases contracted primarily in warmer locations. The life cycle of causative organisms and current therapy are reviewed.

    The mammalian cutaneous low-threshold mechanoreceptors (LTMRs) are a diverse set of primary somatosensory neurons that function to sense external mechanical force. Generally, LTMRs are composed of Aβ-LTMRs, Aδ-LTMRs, and C-LTMRs, which have distinct molecular, physiological, anatomical, and functional features. The specification and wiring of each type of mammalian cutaneous LTMRs is established during development by the interplay of transcription factors with trophic factor signalling. In this review, we summarize the cohort of extrinsic and intrinsic factors generating the complex mammalian cutaneous LTMR circuits that mediate our tactile sensations and behaviors.

    The creeping verminous dermatitis or cutaneous larva migrans is a parasitosis caused by percutaneous penetration and migration of larval nematode parasites characterized by producing one or more serpiginous erythematous, indurated, raised and pruritic lesion. The most common cause of cutaneous larva migrans is the Ancylostoma braziliense located in warm climate zones. In the present study, authors reported a case of cutaneous larva migrans with a characteristic clinical picture: erythematous-papular and vesicular lesion and serpiginous path, with progressive, and pruritic growth and it shown that a living area with immigration, tropical weather conditions and poverty may lead to this common infection.

    We report an imported case of cutaneous leishmaniasis in a 37-year-old man from Saudi Arabia caused by Leishmania major. He presented with non-healing nodulo-ulcerative lesions with a "volcanic crater" on the lower limbs. It was clearly cutaneous leishmaniasis - a rare disease in China - as reflected by the patient's clinical history, the lesions' morphology, histopathological examination, culture and PCR analysis of the lesions. The patient was completely cured after two cycles of sodium stibogluconate treatment. This case report demonstrates that dermatologists should be aware of sporadic cutaneous leishmaniasis cases in non-endemic areas. PMID:27438208

    Full Text Available Cutaneous T cell lymphomas (CTCLs are a heterogeneous group of extranodal non-Hodgkin’s lymphomas that are characterized by a cutaneous infiltration of malignant monoclonal T lymphocytes. They typically afflict adults with a median age of 55 to 60 years, and the annual incidence is about 0.5 per 100,000. Mycosis fungoides, Sézary syndrome, and primary cutaneous peripheral T cell lymphomas not otherwise specified are the most important subtypes of CTCL. CTCL is a complicated concept in terms of etiopathogenesis, diagnosis, therapy, and prognosis. Herein, we summarize advances which have been achieved in these fields.

    1990-06-01

    Superpulsing the carbon dioxide laser allows delivery of high energy pulses separated by short pauses during which tissue cooling can occur.1 This new technology can provide several important advantages in cutaneous surgery over similar procedures performed with conventional continuous discharge carbon dioxide laser systems. In the excisional mode, there is a two-thirds reduction in thermal necrosis of the wound edge.2 This should translate into more rapid healing3 and increased rate of gain in tensile strength. In the vaporizational mode, precise, superficial and bloodless ablation of multiple benign appendigeal tumors is possible with less thermal damage yielding excellent cosmetic results. The establishment through additional research of accurate laser parameters, pulse duration, peak energy levels, and frequency of pulses, will help improve the specificity of the laser-tissue interaction to provide even better surgical results.

    2005-03-01

    Full Text Available Nuclear, biological and chemical warfare have in recent times been responsible for an increasing number of otherwise rare dermatoses. Many nations are now maintaining overt and clandestine stockpiles of such arsenal. With increasing terrorist threats, these agents of mass destruction pose a risk to the civilian population. Nuclear and chemical attacks manifest immediately while biological attacks manifest later. Chemical and biological attacks pose a significant risk to the attending medical personnel. The large scale of anticipated casualties in the event of such an occurrence would need the expertise of all physicians, including dermatologists, both military and civilian. Dermatologists are uniquely qualified in this respect. This article aims at presenting a review of the cutaneous manifestations in nuclear, chemical and biological warfare and their management.

    Reflectance confocal microscopy (RCM) is a high-resolution emerging imaging technique that allows non-invasive diagnosis of several cutaneous disorders. A systematic review of the literature on the use of RCM for the study of infections and infestations has been performed to evaluate the current use of this technique and its possible future applications in this field. RCM is particularly suitable for the identification of Sarcoptes scabies, Demodex folliculorum, Ixodes, Dermatophytes and Candida species in the clinical practice and for the follow-up after treatment. The cytopathic effect of herpes simplex virus, varicella zoster virus and molluscipoxvirus is also detectable by this imaging technique even in a pre-vesicular stage. In addition, thanks to its non-invasiveness, RCM allows pathophysiological studies. PMID:26387660

    Topically applied natural antioxidants can be an effective treatment for inhibiting oxidative damage and photoaging of the skin. Due to the barrier function of the stratum corneum (SC), it is necessary to use an enhancement approach to promote the cutaneous absorption of natural antioxidants. Some factors that should be considered when developing delivery systems for natural antioxidants include increased solubility, enhanced storage stability, improved permeability and bioavailability, skin targeting, and minimal side effects. This review describes the skin delivery systems for natural antioxidant permeation that have been developed during the last decade. The antioxidants introduced include vitamins, polyphenols, and carotenoids. Various types of formulations are employed to improve the skin penetration of the antioxidants, such as hydrogels, cyclodextrin, microemulsions, nanoparticles, liposomes and niosomes. This review focuses on the introduction of natural antioxidants used in skin protection, the mechanisms of antioxidant activity on the skin, and formulation designs for enhancing absorption and efficacy.

    Lauric acid (C12:0) and sapienic acid (C16:1Δ6) derived from human sebaceous triglycerides are potent antimicrobials found at the human skin surface. Long-chain bases (sphingosine, dihydrosphingosine and 6-hydroxysphingosine) are also potent and broad-acting antimicrobials normally present at the skin surface. These antimicrobials are generated through the action of ceramidases on ceramides from the stratum corneum. These natural antimicrobials are thought to be part of the innate immune system of the skin. Exogenously providing these lipids to the skin may provide a new therapeutic option, or could potentially provide prophylaxis in people at risk of infection.
