Palmoplantar pustular psoriasis is a clinical psoriasis variant characterised by a high impact on quality of life and poor response to biologics approved for plaque type psoriasis.The recombinant interleukin-1 (IL-1) receptor antagonist anakinra has been recently used for the treatment of isolated refractory cases of generalised pustular psoriasis with contrasted results. To report the clinical response in two patients treated with anakinra as salvage therapy in two patients with severe palmoplantar pustular psoriasis refractory to currently available antipsoriatic systemic therapies. Anakinra was given subcutaneously at the daily dose of 100 mg, and clinical response was evaluated using the palmoplantar psoriasis area and severity index (PPPASI). Only partial and transient responses were observed in both patients, who had to stop anakinra due to lack of efficacy and to side effects. Anakinra appears to provide only partial clinical improvement in refractory palmoplantar pustular psoriasis. Prospective clinical studies on larger populations are warranted to investigate more accurately both efficacy and safety of IL-1-inhibiting strategies in pustular psoriasis. © 2014 British Association of Dermatologists.

Berk, David R

Terra firma-forme dermatosis is an idiopathic condition characterized by acquired, dirtlike plaques despite normal hygiene. A diagnosis can be reached by removing lesions with gentle alcohol swabbing. Although Terra firma-forme dermatosis was first described more than 20 years ago and is thought to be not uncommon in clinical practice, it has never been systematically studied. There are few publications about this condition, including no case series of more than six patients. In particular, little is known about the incidence, peak age groups, and most common locations of Terra firma-forme dermatosis. A retrospective review was conducted to identify cases of Terra firma-forme dermatosis in a single-provider practice consisting of 55% pediatric and 45% adult patients. Thirty-one patients with Terra firma-forme dermatosis were identified, including 10 who presented with Terra firma-forme dermatosis as their primary concern. Only two patients were older than 17 years. The median duration of lesions was 4 months. The most common lesion locations were the neck, ankles, and face. Before presenting to the dermatology clinic, three patients had undergone endocrine evaluations, and four had been prescribed topical corticosteroids. Terra firma-forme dermatosis is relatively common and most often occurs in children on the neck or posterior malleolus. This series exemplifies the importance of recognizing Terra firma-forme dermatosis so as to provide rapid relief for patients and avoid unnecessary tests and treatments. © 2011 Wiley Periodicals, Inc.

Hazarika, Debeeka

2009-01-01

Two multigravidae aged 27 and 29 years, with previous uneventful pregnancies, second being psoriatic, reported at 24 and 28 weeks of pregnancies, with generalized pustular lesions. Laboratory findings, including serum calcium were normal. Ultrasonography showed normal fetal growth. Histopathology confirmed pustular psoriasis. Patients were put on cyclosporine 3 mg/ kg weight/ day after failure of an initial systemic steroid. Blood pressure, pulse, and fetal heart sounds were recorded every 12 hours, and ultrasonography and blood parameters, biweekly. Cyclosporine was tapered and stopped after delivery of two healthy babies at 38 weeks. We conclude that cyclosporine can be an option in the management of pustular psoriasis of pregnancy or psoriasis with pustulation in pregnancy.

Eosinophilic pustular folliculitis: a review of the Japanese published works.

Eosinophilic pustular folliculitis (EPF), also known as Ofuji's disease, is an inflammatory dermatosis that was first described in Japan in 1970. More than 300 cases have been reported so far, and 113 Japanese cases have been reported in Japan since 1980. To comprehend the characteristics of Japanese EPF cases, we classified these cases into three types: classic, immunosuppression-associated (IS-EPF), and infancy-associated (I-EPF). Trends in age of onset and in distribution and characterization of eruptions differed between the types. We found 91 cases of classic EPF (mean age, 39.7 years), consisting of 66 males (73%) and 25 females (27%), in most of which eruptions primarily affected the face; 18 cases of IS-EPF (44.2 years), consisting of 15 males (83%) and three females (17%), in which eruptions affected the face less predominantly; and four cases of I-EPF (7.0 years), consisting of two males (50%) and two females (50%), primarily affecting the scalp. The number of IS-EPF cases has increased since the late 1990s, reflecting the increasing number of HIV-positive patients in Japan. Systemic non-steroidal anti-inflammatory drugs were effective in more than 70% of cases. Dimethyl diphenyl sulfone, antibiotics including minocycline, psoralen plus ultraviolet A therapy and ultraviolet B treatments worked in some cases. Topical steroids and tacrolimus were also effective in some cases of EPF, while topical indomethacin was less effective. © 2012 Japanese Dermatological Association.

1993-06-01

A newborn black boy had two facial blisters at birth that progressed to bullous lesions over the trunk, genitals, extremities, and oral and tracheal mucosa. A biopsy specimen demonstrated a subepidermal bulla with mixed eosinophilic and neutrophilic, inflammatory infiltrate. Direct immunofluorescence showed linear IgA, IgG, and C3 depositions along the basement membrane zone, consistent with a diagnosis of childhood linear IgA bullous dermatosis (chronic bullous dermatosis of childhood). The skin disease was controlled with combined prednisone and dapsone. This is the youngest reported patient with the disease. Linear IgA bullous dermatosis should be considered in the differential diagnosis of blistering diseases of the newborn, and immunofluorescence should be performed on a skin biopsy specimen.

We report a case of 61-yr-old man with stable psoriasis who progressively developed generalized pustular eruption, erythroderma, fever, and hepatic dysfunction following oral terbinafine. Skin biopsy was compatible with pustular psoriasis. After discontinuation of terbinafine and initiating topical corticosteroid and calcipotriol combination with narrow band ultraviolet B therapy, patient'S condition slowly improved until complete remission was reached 2 weeks later. The diagnosis of generalized pustular psoriasis (GPP) induced by oral terbinafine was made. To our knowledge, this is the first report of GPP accompanied by hepatic dysfunction associated with oral terbinafine therapy. PMID:17297275

Controversy persists as to whether lichen planus pigmentosus and ashy dermatosis are separate clinical entities. This study was conducted to examine the clinicopathological features and treatment outcome of the two conditions. A retrospective medical chart review of all patients who were diagnosed with lichen planus pigmentosus or ashy dermatosis was conducted. The information collected included the participants' age at onset, site of onset, duration of disease, presence of precipitating factors, distribution of disease, pigmentation and presence of symptoms. In patients from whom a biopsy was taken the histopathological reports were included. Altogether 26 patients with ashy dermatosis and 29 with lichen planus pigmentosus were included in the study. Compared with ashy dermatosis, lichen planus pigmentosus had a more localised distribution with a preponderance for facial involvement, compared with the truncal preponderance in ashy dermatosis. Ashy dermatosis tended to have a more stable clinical course than lichen planus pigmentosus, which was more likely to wax and wane. The utility of histopathology in differentiating between the two conditions is low. Ashy dermatosis and lichen planus pigmentosus, as defined in this study, appear to be two separate clinical entities with distinguishable clinical features and natural histories. © 2018 The Australasian College of Dermatologists.

Plaque psoriasis and pustular psoriasis are overlapping, but distinct, disorders. The therapeutic response to biologics supports the pivotal role of the tumour necrosis alpha (TNF-?)/ interleukin (IL)-23/IL-17/IL-22 axis in the pathogenesis of these disorders. Recently, functional activation of the IL-36 receptor (IL-36R) was discovered to be another driving force in the pathogenesis of psoriasis. This was first highlighted by the discovery that a loss-of-function mutation of the IL-36R antagonist (IL-36Ra) causes pustular psoriasis. Although the TNF-?/IL-23/IL-17/IL-22 axis and the functional activation of IL-36R are fundamentally involved in plaque psoriasis and pustular psoriasis, respectively, the 2 pathways are closely related and mutually reinforced, resulting in full-blown clinical manifestations. This review summarizes current topics on how IL-36 agonists (IL-36?, IL-36?, IL-36?) signal IL-36R, the pathological expression of IL-36 agonists and IL-36Ra in plaque and pustular psoriatic lesions, and the cross-talk between the TNF-?/IL-23/IL-17/IL-22 axis and the functional activation of IL-36R in the epidermal milieu.

Challenges of biological therapy in patients with pustular psoriasis coexisting with psoriatic arthritis

Full Text Available Introduction . Psoriasis is a chronic inflammatory skin disease affecting approximately 2–3% of the general population. It is a condition with immunological and genetic background, coexisting with psoriatic arthritis in about 25% of cases. Biologic drugs have brought a significant improvement in managing the disease, however they are not approved for the treatment of pustular psoriasis. An increasing number of reports indicate the efficacy of biological drugs in pustular psoriasis. In some patients there are factors responsible for a worse clinical response to biologic therapy. Objective . Presentation of therapeutic difficulties identified in a patient with pustular psoriasis and psoriatic arthritis. Case report . We report a case of a 48-year-old man with generalized pustular psoriasis coexisting with psoriatic arthritis in whom therapy with multiple biologic drugs (adalimumab, infliximab, golimumab, ustekinumab has failed to bring a satisfactory improvement. Conclusions . Further studies are needed to verify the efficacy and pos­sibly approve biological drugs for the treatment of pustular psoriasis. Also, attempts should be made to identify predictors of poorer response to treatment in order to individualize therapy and prevent the loss of efficacy of biologic drugs during prolonged use.

Flaky paint dermatosis, characterized by extensive, often bilateral areas of flaking and pigmentation, mostly in sun unexposed areas is considered a feature of kwashiorkor in both children and adults, and must be differentiated from other dermatosis, including chapped and xerotica skin, and pellagra. In this case series we provide evidence that malnourished patients with flaky paint dermatosis and infection/inflammation shown laboratory data suggestive of indoleamine 2,3-dioxygenase (IDO) activation, besides decreased urinary excretion of N1-methylnicotinamide (N1 MN), a marker of pellagra. We study nine adult patients showing flaky paint dermatosis and clinical features of infection or inflammation, and increased serum C-reactive protein, characteristic of the presence of acute phase response syndrome. As a group, they had low or deficient urinary N1 MN excretion (0.52 ± 0.39 mg/g creatinine) compatible with pellagra. They also showed low serum tryptophan levels (dermatosis showed laboratory data suggestive of IDO activation, besides decreased N1 MN urinary excretion. Taken together, the data support the idea that flaky paint dermatosis could be a skin manifestation of niacin deficiency. Copyright © 2015 Elsevier Inc. All rights reserved.

We describe a 30-year-old parturient with acute generalised pustular psoriasis who presented for urgent caesarean section. A multidisciplinary team was involved and general anaesthesia was used successfully. Management of this condition is discussed and the literature reviewed. While generalised pustular psoriasis or impetigo herpetiformis is well recognised in pregnancy, it has not hitherto been reported in obstetric anaesthesia literature. The purpose of this article is to delineate the clinical picture of this disease, its treatment, and the effect on the mother and the fetus.

Generalised pustular psoriasis, psoriatic arthritis and nephrotic syndrome associated with systemic amyloidosis.

David, M; Abraham, D; Weinberger, A; Feuerman, E J

1982-09-01

The case report is presented of a psoriatic patient with arthropathy, generalised pustular psoriasis and nephrotic syndrome, in whom systemic amyloidosis developed. The literature reports 13 cases of psoriasis associated with amyloidosis, 3 of whom suffered from pustular psoriasis as does our case. With the addition of our case, 12 of these 14 had concomitant arthropathy. This seems to suggest that arthritis is an important factor in the appearance of amyloidosis. Rectal biopsy and/or renal biopsy may be helpful in establishing the diagnosis of amyloidosis relatively early in patients with psoriatic arthritis.

Bowel-associated dermatosis-arthritis syndrome (BADAS) is a neutrophilic dermatosis, characterized by the occurrence of arthritis and skin lesions related to bowel disease with or without bowel bypass. We report an unusual case of BADAS in a 15-year-old white male with congenital aganglionosis of the colon and hypoganglionosis of the small intestine and multiple bowel surgeries in childhood complicated by short bowel syndrome. He presented with recurrent peripheral polyarthritis, tenosynovitis, and painful erythematous subcutaneous nodules located on the dorsolateral regions of the legs and on the dorsa of the feet. Histological examination disclosed a neutrophilic dermatosis confirming the diagnosis of BADAS.Although an uncommon disease, especially at pediatric age, it is important to evoke the diagnosis of BADAS in children and adolescents with bowel disease, because treatment options and prognosis are distinct from other rheumatologic conditions.

Eosinophilic pustular folliculitis (EPF) is a chronic intractable pruritic dermatosis characterized by massive eosinophil infiltrates involving the pilosebaceous units. Recently, EPF has been regarded as an important clinical marker of HIV infection, and its prevalence is increasing in number. The precise mechanism by which eosinophils infiltrate into the pilosebaceous units remains largely unknown. Given that indomethacin, a COX inhibitor, can be successfully used to treat patients with EPF, we can assume that COX metabolites such as prostaglandins (PGs) are involved in the etiology of EPF. To determine the involvement of PGs in the pathogenesis of EPF. We performed immunostaining for PG synthases in EPF skin lesions. We examined the effect of PGD(2) on induction of eotaxin, a chemoattractant for eosinophils, in human keratinocytes, fibroblasts, and sebocytes and sought to identify its responsible receptor. Hematopoietic PGD synthase was detected mainly in infiltrating inflammatory cells in EPF lesions, implying that PGD(2) was produced in the lesions. In addition, PGD(2) and its immediate metabolite 15-deoxy-Δ 12,14-PGJ(2) (15d-PGJ(2)) induced sebocytes to produce eotaxin-3 via peroxisome proliferator-activated receptor gamma. Consistent with the above findings, eotaxin-3 expression was immunohistochemically intensified in sebaceous glands of the EPF lesions. The PGD(2)/PGJ(2)-peroxisome proliferator-activated receptor gamma pathway induces eotaxin production from sebocytes, which may explain the massive eosinophil infiltrates observed around pilosebaceous units in EPF.

Full Text Available A two-year-old spayed female mixed-breed dog was presented with a five-day history of hemorrhagic gastroenteritis and fever. On physical examination, the dog was lethargic and clinically dehydrated. The skin of the entire ventral abdomen extending to both flanks was erythematous, swollen and painful on palpation. Histopathological examination of skin biopsies revealed a severe diffuse neutrophilic dermatitis and panniculitis, resembling the subcutaneous form of Sweet’s syndrome in humans. A large part of the skin lesion developed full-thickness necrosis. After intensive care, three surgical wound debridements and wound adaptations, the wound healed by secondary intention within ten weeks. In the absence of infection of the skin or neoplasia, a diagnosis of neutrophilic dermatosis and panniculitis, resembling the subcutaneous form of acute febrile neutrophilic dermatosis, was made.

This report describes a case of neutrophilic dermatosis in a dog, with a number of clinical and pathological similarities to human pyoderma gangrenosum. A seven-year-old, female German shepherd dog with a history of non-erosive idiopathic polyarthritis was presented with severe facial swelling, bilateral erosivoulcerative lesions on the muzzle and multiple, eroded, dermal-subcutaneous nodules on the cranial trunk. Histopathological examination of skin biopsies revealed a necrotising neutrophilic dermatitis. No infectious agents could be detected using specific stains, immunohistochemistry, serology and bacterial aerobic, anaerobic or fungal cultures. A sterile neutrophilic dermatosis resembling human pyoderma gangrenosum was presumptively diagnosed, and the patient showed an excellent response to treatment with prednisone and ciclosporin.

A 65-year-old pluripathological woman attended our hospital with a cutaneous eruption of sudden appearance after vancomycin treatment. She presented targetoid lesions affecting approximately 25-30% of her body surface, large erosions with mucosal lesions and positive Nikolsky sign. Under the initial clinical suspicion of toxic epidermal necrolysis (TEN), and considering the recent literature of successful use of etanercept in these cases, she was treated with a single dose of this antitumour necrosis factor (anti-TNF) agent. Subsequently, the exanthema progression stopped and resolution of the lesions happened in a few days. Later on, histopathology revealed a subepidermal blister with dense neutrophilic infiltrate and linear deposits of immunoglobulin A (IgA) on the dermoepidermal junction, allowing us to establish the diagnosis of drug-induced linear IgA dermatosis mimicking TEN. Linear IgA dermatosis can have severe clinical manifestations, even mimicking TEN, and can have high mortality, especially in drug-induced cases. We have not found any other report of linear IgA dermatosis treated with etanercept in the English literature. Anti-TNF medications could represent useful therapeutic alternatives in this dermatosis. © 2017 British Association of Dermatologists.

We report a 68-year-old woman with chroniclymphocytic leukemia, who developed numerous,pruritic, edematous, and vesicobullous skin lesionsof the face and extremities over the course of severalmonths. The diagnosis of eosinophilic dermatosis ofhematologic malignancy (EDHM) was made basedon the clinical history and histopathologic features.Owing to the possible link between EDHM and amore aggressive underlying CLL, she was startedagain on chemotherapy. This case serves as areminder that, although the precise pathogenesis ofEDHM remains unclear, the paraneoplastic disorderis the result of immune dysregulation. Patientswho develop EDHM should undergo prompthematologic/oncologic evaluation.

Feline familial pedal eosinophilic dermatosis in two littermates

Directory of Open Access Journals (Sweden)

Charline Pressanti

2015-04-01

Full Text Available In cats, the most common eosinophilic dermatoses are feline miliary dermatitis and eosinophilic granuloma complex. The most commonly identified underlying cause is a hypersensitivity reaction. Few cases of familial forms of eosinophilic dermatoses are reported in the literature. Two young adult cats from the same litter presented 2 years apart with a severe and chronic fluid or tissue infiltration of the distal part of several limbs. Lesions started on the forelegs and developed on the other limbs. Cytological and histopathological examinations showed lesions consistent with an atypical form of feline eosinophilic dermatosis associated with secondary bacterial infection. In both cats, antibiotics combined with immunosuppressive treatment partially improved the lesions, which continued to progress on a waxing and waning course, even in the absence of treatment. Allergy work-up did not permit the identification of an underlying allergic triggering factor. The severity of the lesions, the unusual presentation and the unsatisfactory response to immunosuppressive therapy in two feline littermates suggested a genetic form of eosinophilic dermatosis.

Generalised pustular psoriasis induced by cyclosporin a withdrawal responding to the tumour necrosis factor alpha inhibitor etanercept.

Science.gov (United States)

Kamarashev, J; Lor, P; Forster, A; Heinzerling, L; Burg, G; Nestle, F O

2002-01-01

We report a 50-year-old male patient with a 15-year history of psoriasis including mutilating psoriatic arthritis, in whom the withdrawal of cyclosporin A induced a generalised pustular exacerbation and a aggravation of the joint condition. Two weekly injections of 25 mg of the tumour necrosis factor alpha inhibitor etanercept led to a rapid improvement of his psoriatic arthritis, as well as regression of the pustular eruption, while residual erythema was still present. The clinical response was reflected by an increase in circulating interleukin (IL) 10 and a decrease in IL-6 and IL-8 serum levels during treatment. We conclude that etanercept may be a safe and effective therapy not only in severe psoriatic arthritis, but also in cases of pustular rebound after withdrawal of immunosuppressive agents.

Short- and Long-Term Management of an Acute Pustular Psoriasis Flare: A Case Report.

Science.gov (United States)

Georgakopoulos, Jorge R; Ighani, Arvin; Yeung, Jensen

Generalised pustular psoriasis (GPP) and acrodermatitis continua of Hallopeau (ACH) are chronic, relapsing variants of pustular psoriasis proven to be remarkably challenging to treat. Due to their uncommon presentation, there are few described cases in literature and scarce evidence for management. Further information is needed to help dermatologists formulate treatment plans for patients presenting with such diseases. We report the case of a 68-year-old man with a 3-year history of psoriasis presenting to our clinic with a severe breakout of GPP and associated ACH. The patient underwent treatment with cyclosporine A (200 mg PO twice daily) for a period of 2 weeks. This provided dramatic improvement in disease symptoms, with clearance of pustules, remarkable reduction of ACH lesions, and absence of pain. The patient was transitioned to infliximab (5 mg/kg intravenous) and apremilast (30 mg PO twice daily), displaying minimal GPP relapse and well-controlled onychodystrophy for several months. This case supports the use of cyclosporine as a first-line agent in providing immediate symptomatic relief for pustular psoriasis flares. Transitioning to infliximab and apremilast combination therapy offers a unique treatment regime for long-term GPP and ACH management.

2017-01-01

Impetigo herpetiformis (pustular psoriasis of pregnancy) is a rare dermatosis of pregnancy that typically starts in the 2 nd half of pregnancy and resolves postpartum. It may recur in subsequent pregnancies. I present a case of 23 year old female gravida 4 para 3 with recurrent impetigo herpetiformis at 26 weeks gestation. She presented with a one month history of pustular lesions which responded to treatment with prednisone. She delivered at term with a favourable outcome. The disease resolved one month postpartum. This was the second recurrence of the disease. She had her first episode of impetigo herpetiformis during the second pregnancy. The disease recurred in the 3 rd pregnancy and resulted in a still birth.

Linear IgA dermatosis has been increasingly associated with inflammatory bowel diseases, particularly ulcerative colitis. A 13-year-old male patient with an 11-month history of ulcerative colitis developed vesicles, pustules and erosions on the skin of the face, trunk and buttocks and in the oral mucosa. The work-up revealed a neutrophil-rich sub-epidermal bullous disease and linear deposition of IgA along the dermoepidermal junction, establishing the diagnosis of linear IgA dermatosis. The patient experienced unsatisfactory partial control of skin and intestinal symptoms despite the use of adalimumab, mesalazine, prednisone and dapsone for some months. After total colectomy, he presented complete remission of skin lesions, with no need of medications during two years of follow-up. A review of previously reported cases of the association is provided here and the role of ulcerative colitis in triggering linear IgA dermatosis is discussed.

Linear immunoglobulin (Ig)A/G bullous dermatosis (LAGBD) is an autoimmune bullous disease characterized by formation of subepidermal blisters and linear deposition of IgA and IgG antibodies along the basement membrane zone (BMZ). The association between linear IgA bullous dermatosis and ulcerative colitis (UC) is well recognized, but reports of UC-associated LAGBD are lacking. We have reported a 24-year-old man suffering from LAGBD associated with UC, which occurred before exacerbations of skin rash. A skin biopsy indicated a subepidermal blister with an infiltration of primarily neutrophils and eosinophils in the dermis. Direct immunofluorescence (IF) studies showed a linear deposition of IgA, IgG and C3c. Indirect IF of human skin revealed IgA and IgG anti-BMZ autoantibodies. Indirect IF of 1 M NaCl-split human skin demonstrated reactivity of IgA and IgG antibodies at the epidermal side. Immunoblotting showed that IgG antibodies reacted to the BP180 NC16a domain and 120-kDa linear IgA dermatosis-1, and enzyme-linked immunoassay detected IgG anti-BP230 antibodies. Administration of prednisolone and diaminodiphenyl sulfone (DDS) via the p.o. route improved skin lesions and bowel conditions. These results suggest that the bowel inflammation observed in UC may have a causative effect of initiation of the immune response to the skin and development of the bullous skin lesions in LAGBD. A combination of DDS and corticosteroid could be a recommended therapeutic option for patients with LAGBD with UC. © 2017 Japanese Dermatological Association.

Sweet's syndrome – a comprehensive review of an acute febrile neutrophilic dermatosis

Directory of Open Access Journals (Sweden)

Cohen Philip R

2007-07-01

Full Text Available Abstract Sweet's syndrome (the eponym for acute febrile neutrophilic dermatosis is characterized by a constellation of clinical symptoms, physical features, and pathologic findings which include fever, neutrophilia, tender erythematous skin lesions (papules, nodules, and plaques, and a diffuse infiltrate consisting predominantly of mature neutrophils that are typically located in the upper dermis. Several hundreds cases of Sweet's syndrome have been published. Sweet's syndrome presents in three clinical settings: classical (or idiopathic, malignancy-associated, and drug-induced. Classical Sweet's syndrome (CSS usually presents in women between the age of 30 to 50 years, it is often preceded by an upper respiratory tract infection and may be associated with inflammatory bowel disease and pregnancy. Approximately one-third of patients with CSS experience recurrence of the dermatosis. The malignancy-associated Sweet's syndrome (MASS can occur as a paraneoplastic syndrome in patients with an established cancer or individuals whose Sweet's syndrome-related hematologic dyscrasia or solid tumor was previously undiscovered; MASS is most commonly related to acute myelogenous leukemia. The dermatosis can precede, follow, or appear concurrent with the diagnosis of the patient's cancer. Hence, MASS can be the cutaneous harbinger of either an undiagnosed visceral malignancy in a previously cancer-free individual or an unsuspected cancer recurrence in an oncology patient. Drug-induced Sweet's syndrome (DISS most commonly occurs in patients who have been treated with granulocyte-colony stimulating factor, however, other medications may also be associated with DISS. The pathogenesis of Sweet's syndrome may be multifactorial and still remains to be definitively established. Clinical and laboratory evidence suggests that cytokines have an etiologic role. Systemic corticosteroids are the therapeutic gold standard for Sweet's syndrome. After initiation of treatment

2009-02-01

We report a case of a 46-year-old man with ulcerative colitis being treated with oral prednisolone and azathioprine. Two weeks after the initiation of azathioprine he presented with fever, fatigue, myalgias and arthralgias and a painful cutaneous eruption that was most marked in a sun-exposed distribution. This was accompanied by loose, non-bloody diarrhoea. Histopathological assessment of a skin biopsy supported a diagnosis of a neutrophilic dermatosis. The azathioprine was temporarily withheld and oral prednisolone was increased as it was thought that the neutrophilic dermatosis was associated with the underlying ulcerative colitis. The patient's symptoms and cutaneous eruption resolved quickly and azathioprine was re-introduced. Within 24 h, systemic symptoms returned along with a florid recrudescence of his cutaneous eruption. This rapidly improved upon withdrawal of azathioprine.

2012-10-01

Full Text Available Probiotics exhibit widespread effects on homeostasis and immunomodulation of both mucosal and systemic immunity. Probiotics counter weight aggressive commensals in the body and reinforce the barrier function of the epithelium while also contributing to the regulation of innate and adaptive immune responses of the host under healthy or pathogenic conditions. Probiotics could be used for prevention or treatment of chronic allergic and inflammatory diseases, such as inflammatory bowel disease (IBD and atopic dermatitis. We describe a case of pustular psoriasis where probiotics were used for the treatment successfully.

2017-01-01

Full Text Available Linear IgA bullous dermatosis (LABD is an autoimmune vesiculobullous disease, which is typically idiopathic but can also rarely be caused by medications or infections. Vancomycin is the most common drug associated with LABD. Lesions typically appear 24 hours to 15 days after the first dose of vancomycin. It is best characterized pathologically by subepidermal bulla (blister formation with linear IgA deposition at the dermoepidermal junction. Here we report an 86-year-old male with a history of left knee osteoarthritis who underwent a left knee arthroplasty and subsequently developed a prosthetic joint infection. This infection was treated with intravenous vancomycin as well as placement of a vancomycin impregnated joint spacer. Five days following initiation of antibiotic therapy, he presented with a vesiculobullous eruption on an erythematous base over his trunk, extremities, and oral mucosa. The eruption resolved completely when intravenous vancomycin was discontinued and colchicine treatment was begun. Curiously, complete resolution occurred despite the presence of the vancomycin containing joint spacer. The diagnosis of vancomycin-induced linear IgA bullous dermatosis was made based on characteristic clinical and histopathologic presentations.

El cuadro respondió inicialmente bien a la dapsona, pero debido a un aumento de enzimas hepáticas y bilirrubina se rotó a terapia tópica con clobetasol y pimecrolimus, con buena respuesta. Efectuamos una revisión del cuadro enfatizando que el mismo constituye una inflamación del epitelio infundibular y no folicular constituyendo un patrón de respuesta a múltiples causas, algunas o la mayoría no bien conocidas.A case of the so called eosinophilic pustular folliculitis or Ofuji´s disease, without blood eosinophilia nor immunosuppression is reported. The patient responded at first well to Dapsone, but an increase of the hepatic enzymes and bilirubin was detected and only topical therapy with clobetazol and pimecrolimus was carried out with a good response. A revision of the disease with emphasis in the concept of infundibulitis rather than folliculitis was made. The eosinophilic pustular folliculitis is a pattern of response to multifactorial, mostly unknown, causes and not a single disease.

2008-11-01

Pyodermatitis-pyostomatitis vegetans (PPV) is a rare chronic disorder often associated with inflammatory bowel disease. We report an isolated case involving the oral, labial and nasal mucosa. A 28-year-old man, in good general condition, presented with a 2-year history of painless stomatitis. The physical examination revealed pustular and exophytic lesions of the jugal, gingival and palatine mucosa on an erythematous background, as well as some pustular and crusted lesions of the lower lip and nostrils. Histopathological analysis revealed epithelial hyperplasia and a suprabasal cleft with some signs of acantholysis and numerous neutrophils and eosinophils. Direct and indirect immunofluorescence assay was negative. There was no associated bowel disease. We concluded on a diagnosis of PPV of younger subjects. The lesions disappeared with oral corticosteroids but with steroid dependency. PPV is a rare dermatosis associated in more than 75% of cases with inflammatory bowel disease, usually ulcerative colitis. Lesions of the oral mucosa are a constant finding and are characterised by aseptic pustules on an erythematous background. Skin lesions are pustular and more or less exophytic. To our knowledge, there have been no reports to date of intranasal lesions of PPV.

Species Pseudocowpox virus (PCPV; family Poxviridae) is known to cause pustular cutaneous disease in cattle. We describe an outbreak of pseudocowpox with an unusual clinical picture in a free-stall dairy herd of ~80 cows. Approximately 90% of the cows had vesicles, erosions, papules, and scabs on the vulva and vaginal mucosa. Histologic analysis of biopsy tissues indicated a primary, although not specified, viral infection. Transmission electron microscopy revealed parapoxvirus particles in both tissue and vesicular materials. Deep sequencing analysis of extracted DNA from swabbed vesicle areas gave a contig of nearly 120,000 nucleotides, matching the PCPV strain VR 634 with 100% identity. Analyses confirmed the absence of other potential causes of pustular vulvovaginitis such as bovine herpesvirus 1 and Ureaplasma diversum. A rolling cow brush was suspected to be the fomite.

Acral manifestations of Sweet syndrome (neutrophilic dermatosis of the hands).

Science.gov (United States)

Wolf, Ronni; Tüzün, Yalçın

Neutrophilic dermatosis of the hand (NDH) is a rare localized variant of the syndrome, originally described two decades ago by Strutton et al. The lesions of NDH and Sweet syndrome are similar, as indicated in the first report of NDH. Both diagnoses are characterized by an acute onset of fever, leukocytosis, and tender, erythematous infiltrated plaques. There are also bullae and ulceration in NDH, in contrast to Sweet syndrome, in which bullae are quite uncommon, especially at the early stages. Similar to Sweet syndrome, the majority of NDH patients are women (69%). Patients with NDH present with fever, peripheral neutrophilia, leukocytosis, and/or an elevated erythrocyte sedimentation rate or C-reactive protein level, but at a significantly lower rate than those in Sweet syndrome (33%). Similar to Sweet syndrome, NDH has been associated with the following conditions: Malignancies (particularly hematological [21%], most common of which is acute myelogenous leukemia, but many other malignancies as well), inflammatory bowel disease (19%), medication and vaccination-related eruptions, bacterial and viral infections, rheumatologic diseases, and others. The clues to the diagnosis of NDH are the same as for Sweet syndrome. Awareness of this diagnosis is important not only to avoid unnecessary medical and surgical therapy and to expediently initiate the administration of steroids for this highly responsive dermatosis, but also to conduct an appropriate workup to exclude associated diseases, especially malignancies.

Impetigo herpetiformis (IH) is a very rare type of dermatosis seen in pregnancy. According to the published work, IH during pregnancy is associated with the risk of stillbirth, and obstetric management in such cases is very important. Early recognition is important to reduce both maternal and fetal morbidity. We present a case of IH resistant to corticosteroid therapy in a 27-year-old pregnant woman where the pregnancy was terminated by the induction of labor. © 2014 The Authors.

Not all pustules are infective in nature: acute generalised exanthematous pustulosis causing pustular eruptions in an elderly woman.

Science.gov (United States)

Kwah, Y C; Leow, Y H

2005-07-01

Acute generalised exanthematous pustulosis (AGEP) is an adverse drug reaction that can occur in any age group. It is commonly mistaken as pustular psoriasis or cutaneous infection, resulting in unnecessary commencement of medications such as methotrexate and antibiotics that can cause harm to the patient or interact and adversely affect the efficacy of other medications. Early diagnosis of AGEP avoids unnecessary investigations and treatment, which not only can harm the patient but also escalate health care, as the condition is self-limiting. This case report illustrates AGEP secondary to Cefaclor occurring in a 72-year-old Chinese woman. Although the literature has documented the occurrence of AGEP with Cefaclor, the unique feature of this case is the occurrence of AGEP following repeated uneventful courses of Cefaclor. This case highlights that AGEP must never be forgotten in the work-up for pustular eruptions in an elderly patient.

Acquired perforating dermatosis (APD) is an uncommon disease characterized by lesions exhibiting transepidermal elimination of collagen or elastic fibers. APD affects adults and is associated with systemic diseases, mainly diabetes mellitus and renal failure. We present 8 cases of APD. Seven patients had concomitant diabetes mellitus with or without chronic renal failure, and 1 had alcoholic cirrhosis. In the patients with chronic renal failure, the onset of APD coincided with transient worsening of renal function. The mean increase in creatinine concentrations above baseline was 1.14mg/dL. Acute deterioration of renal function may be involved in APD. Further studies are needed to investigate this association. Copyright © 2013 Elsevier España, S.L. y AEDV. All rights reserved.

Impetigo herpetiformis (IH) is a rare dermatosis arising during the third trimester of pregnancy which is generally considered as a form of pustular psoriasis of unknown aetiology. Clinically it is characterized by erythematous plaques surrounded by sterile pustules associated with fever, diarrhea, sweating and increasing risk of stillbirth for placental insufficiency. We describe a case of developed erythematous plaques surrounded by pustules localised initially to the trunk of a 35-year-old woman at the 34th week of gestation after 5 days of treatment with N-Butyl-Scopolammonium, and which later involved the upper and lower limbs. Skin histology confirmed the diagnosis of generalised pregnancy pustular psoriasis (impetigo herpetiformis). IH is reported to be associated with hypocalcemia, hypoparathyroidism, use of oral contraceptives and bacterial infections. This is the first report suggesting the potential role of drugs other than oral contraceptives in the pathogenetic mechanism of this disease. In this case an adverse cutaneous reaction to BB could be the cause of the development of Koebner isomorphism.

We describe an outbreak of infectious pustular vulvovaginitis caused by Caprine herpesvirus 1 (CpHV1) in a group of approximately 200, 8 month old virgin does that were imported to Victoria from New Zealand. CpHV1 was isolated in cell cultures from vaginal swabs from three of three affected does but not from two bucks that had been with the does. The identity of the virus as a herpesvirus was confirmed by negative stain electron microscopy. Restriction endonuclease DNA fingerprint analysis showed that the DNA fingerprints were similar, but not identical, to previously described CpHV1 isolates made in New Zealand, New South Wales, and in other parts of the world. Acute and convalescent phase sera from selected does supported the diagnosis of CpHV1 infection. It is most likely that the disease was initiated by reactivation of latent virus in at least one of four bucks that served the does, since each was positive for CpHV neutralising antibody when first tested. This is the first report of CpHV infectious pustular vulvovaginitis in goats in Victoria and to our knowledge appears to be one of the largest outbreaks recorded anywhere.

Perforating dermatoses are a group of skin diseases characterized by transepidermal elimination of dermal material. The disease is divided into two groups: the primary group and the secondary group. The classical or primary perforating dermatoses are subdivided into four types according to the eliminated dermal materials: Kyrle disease, perforating reactive collagenosis, elastosis perforans serpiginosa, and perforating folliculitis. The secondary form is known as acquired perforating dermatosis. The term was proposed in 1989 by Rapini to designate the perforating dermatoses affecting adult patients with systemic disease, regardless of the dermal materials eliminated. This report describes a case of the disease with elimination of collagen and elastic fibers in a patient with chronic renal failure.

Early and Late Onset Side Effects of Photodynamic Therapy

Directory of Open Access Journals (Sweden)

Francesco Borgia

2018-01-01

Full Text Available Photodynamic Therapy (PDT is a non-invasive treatment successfully used for neoplastic, inflammatory and infectious skin diseases. One of its strengths is represented by the high safety profile, even in elderly and/or immuno-depressed subjects. PDT, however, may induce early and late onset side effects. Erythema, pain, burns, edema, itching, desquamation, and pustular formation, often in association with each other, are frequently observed in course of exposure to the light source and in the hours/days immediately after the therapy. In particular, pain is a clinically relevant short-term complication that also reduces long-term patient satisfaction. Rare complications are urticaria, contact dermatitis at the site of application of the photosensitizer, and erosive pustular dermatosis. Debated is the relationship between PDT and carcinogenesis: the eruptive appearance of squamous cell carcinoma (SCC in previously treated areas has been correlated to a condition of local and/or systemic immunosuppression or to the selection of PDT-resistant SCC. Here we review the literature, with particular emphasis to the pathogenic hypotheses underlying these observations.

Adaptor protein complex 1 (AP-1) is an evolutionary conserved heterotetramer that promotes vesicular trafficking between the trans-Golgi network and the endosomes. The knockout of most murine AP-1 complex subunits is embryonically lethal, so the identification of human disease-associated alleles has the unique potential to deliver insights into gene function. Here, we report two founder mutations (c.11T>G [p.Phe4Cys] and c.97C>T [p.Arg33Trp]) in AP1S3, the gene encoding AP-1 complex subunit σ1C, in 15 unrelated individuals with a severe autoinflammatory skin disorder known as pustular psoriasis. Because the variants are predicted to destabilize the 3D structure of the AP-1 complex, we generated AP1S3-knockdown cell lines to investigate the consequences of AP-1 deficiency in skin keratinocytes. We found that AP1S3 silencing disrupted the endosomal translocation of the innate pattern-recognition receptor TLR-3 (Toll-like receptor 3) and resulted in a marked inhibition of downstream signaling. These findings identify pustular psoriasis as an autoinflammatory phenotype caused by defects in vesicular trafficking and demonstrate a requirement of AP-1 for Toll-like receptor homeostasis.

Generalized pustular psoriasis (GPP) is a severe but rare variant of psoriasis. Our objective is to review the clinical profile, comorbidities, and outcome of patients with GPP. A retrospective note review of all patients with adult-onset GPP. A total of 102 patients with adult-onset GPP were diagnosed between 1989 and November 2011, with a female to male ratio of 2 : 1. The mean age at onset of GPP was 40.9 years (range: 21-81 years). Acute GPP was the most common variant seen (95 cases), followed by four localized variants of GPP and three with annular pustular psoriasis. Fever and painful skin were present in 89% of patients, arthritis in 34.7%, and leukocytosis in 78.4%. Common triggers were systemic steroids (45 cases), pregnancy (17 cases), and upper respiratory tract infections (16 cases). A positive family history of psoriasis and GPP was present in 29% and 11%, respectively. Comorbidities included obesity (42.9%), hypertension (25.7%), hyperlipidemia (25.7%), and diabetes mellitus (23.7%). The mean duration of admission and pustular flare for acute GPP was 10.3 days (range: 3-44 days) and 16 days (range: 7-60 days), respectively. Fifty-four patients responded to systemic retinoid, 21 to methotrexate, eight to cyclosporine, and one to adalimumab, but recurrences were common. Our study confirms the poor response of GPP to currently available anti-psoriatic agents, with frequent flare-ups. There is a need for a more effective targeted therapy for this condition. © 2013 The International Society of Dermatology.

Histopathologic examination showed  an increased dermal melanophages (Panel B and a vacuolization of basal cell layer (Panel C, evoking an ashy dermatosis (AD. Paraclinical assessment didn't find any related  disease. Multiple therapy was proposed such as corticosteroids andphototherapy. Evolution was marked by the extension of  lesions in members at five years of follow-up.AD was first described by Ramírez. He called the patients «Los cenicientos». The Spanish term cenicienta means Cinderella, because of this folklore character's close association with ashes from sitting at  home alone by the fireplace. Most cases present  gray–brown macules which are commonly found on the face, arms, neck, and trunk. Histopathologic findings are nonspecific and include vacuolization of the basal layer, pigmentary incontinence and perivascular inflammatory infiltrate. The etiology of AD is unknown. Some authors reported associations with ammonium nitrate, whipworm infestation and HIV seroconversions. Many treatments was proposed such as corticosteroids, dapsone, clofazimine and phototherapy, but the results are not satisfactory. Such as basic research on the pathogenesis and treatment of hypermelanosis continuous, we look for more answers to the questions raised by this case.

Full Text Available Background. Approximately 10 % of the pediatric population suffers from atopic dermatitis, and this disease is most common skin allergic pathology. The influence of thyroid hormones on the development of atopy is known. Study purpose was to evaluate the features of the functional status of the pituitary-thyroid system in children with allergic dermatosis. Materials and methods. 72 children aged from 7 to 18 years were divided into 4 groups: group I — patients who suffer from atopic dermatitis (n = 29, II — children with allergic contact dermatitis (n = 17, III group — patients with simple contact dermatitis (n = 16, IV group — healthy children (n = 10. The levels of thyroxine, thyroid stimulating hormone, antibodies to thyroglobulin (TG were determined. Results. Erythema was found in 95.2 %, edema — in 43.5 %, exudation — in 37.1 %, excoriation — in 43.5 %, lichenification — in 56.4 % of the total group of patients. Dysfunctions of the pituitary-thyroid system, both at the central and peripheral level, were determined. The frequency of antibodies to TG detection in children of the first group was high and exceeded the average population values by 3.7 times (36.7 %, χ2 = 17.5, p < 0.05. The level of TG in all of observed patients was significantly higher than that of in the comparison group. The frequency of detection of antibo­dies to TG in the group of patients with the disease experience more than 10 years exceeded the average population values by 3.2 times (34.0 %, χ2 = 8.1, p < 0.05. Conclusions. Changes in the morpho-functional state of the pituitary-thyroid system, mainly of an autoimmune nature, are revealed in children with allergic dermatosis.

Campbell, Gregory A; Crow, Dennis

2010-07-01

A litter of 3-month-old Pharaoh Hound puppies presented to the referring veterinarian with severe generalized erythematous-crusted papules with pruritus, accompanied by exfoliation and erythema of footpads, inappetence, lethargy, and retarded growth. Three of 5 puppies (2 male and 1 female) were affected. Representative areas were biopsied from 1 affected male puppy and were routinely processed. Histologically, there was marked epidermal hyperplasia with a disorganized appearance of the epidermis and massive parakeratotic hyperkeratosis, compatible with zinc-responsive dermatosis. Low serum zinc concentrations were documented, and the affected animals partially responded to intravenous zinc supplementation but did not respond to oral supplementation. One male puppy died as a result of unrelated causes and was necropsied. The remaining 4 puppies were followed over 2 years. Growth was stunted, and enamel hypoplasia of permanent dentition developed compared with unaffected littermates. Intravenous zinc supplementation at 3-4 week intervals was required to prevent further skin lesion development. One dog died at 3 years of age of renal failure.

Eosinophilic pustular folliculitis (EPF) is characterized by a non-infectious infiltration of eosinophils in the hair follicles. It has three variants: (i) classic EPF; (ii) immunosuppression-associated EPF, which herein is subdivided into HIV-associated (IS/HIV) and non-HIV-associated (IS/non-HIV); and (iii) infancy-associated EPF (I-EPF). The rarity of EPF has hindered our understanding of this entity. To examine the characteristics of EPF, with respect to age, sex, race, and chronology, published in case reports to date, we queried PubMed using the following terms: ("eosinophilic pustular folliculitis" [All Fields] OR "eosinophilic folliculitis" [All Fields]) AND ("1965/1/1" [PDAT]: "2013/12/31" [PDAT]). Additional Japanese cases were collected from Igaku Chuo Zasshi through Ichushi-Web, JDream III, and secondhand quotations from domestic periodicals published in Japan. Proceedings were excluded. The PubMed search produced 275 citations containing 358 cases of EPF (224 men, 132 women, and two of unspecified sex); these cases involved classic EPF (101 Japanese and 81 non-Japanese), IS/HIV (4 Japanese and 85 non-Japanese), IS/non-HIV (4 Japanese and 20 non-Japanese), and I-EPF (4 Japanese and 59 non-Japanese). Ichushi generated an additional 148 citations containing 207 cases of Japanese (148 men and 59 women), which included cases of classic EPF (181 cases), IS/HIV (14 cases), IS/non-HIV (9 cases), and I-EPF (3 cases). There was no sex difference in the classic EPF cases reported between 2003 and 2013, whereas IS/HIV, IS/non-HIV, and I-EPF were predominated by men. There is room for reconsideration of sex differences, particularly with regard to classic EPF. The rarity and specificity of I-EPF in Japan may reflect a state of uncertainty about this entity. © 2015 Japanese Dermatological Association.

Full Text Available El progresivo envejecimiento de la población está provocando el desarrollo como grupo profesional de los cuidadores profesionales de ancianos, los auxiliares de geriatría. Puede considerarse un grupo de riesgo para el desarrollo de dermatosis ocupacional debido a las características del trabajo que desempeñan, con una regular exposición a irritantes cutáneos y a trabajo húmedo. Los estudios centrados en la patología cutánea de este colectivo son escasos. Objetivo: El objetivo de este estudio es describir y analizar las características y los diagnósticos clínicos dermatológicos de los pacientes que trabajan como cuidadores de ancianos valorados en nuestro servicio. Material y métodos: Se ha llevado a cabo un estudio observacional retrospectivo de los datos de 41 pacientes cuidadores de ancianos estudiados en nuestro servicio durante un periodo de 11 años. Resultados: Encontramos un predominio total de mujeres. El lugar de afectación más frecuente fueron las manos. Los diagnósticos más frecuentemente establecidos fueron: Eczema endógeno (39,6%, dermatitis de contacto irritativa (DCI (27,1%, dermatitis de contacto alérgica (DCA (12,5%, Sin lesiones (10,4%, urticaria de contacto al látex (4,2% y otros. Conclusiones: El colectivo de cuidadores de ancianos es un grupo en aumento y de gran importancia social. Al desempeñar una labor que implica un trabajo húmedo se debe considerar un grupo de riesgo para el desarrollo de dermatosis profesionales. En nuestro estudio destaca que el diagnóstico de eczema endógeno, representado por la dermatitis atópica, sea el más frecuente, explicándose esto porque una irritación provocada por un trabajo húmedo y la oclusión pueden desencadenar un eczema en el individuo con un fondo atópico, que en otras condiciones se habría mantenido latente. Son necesarios futuros estudios más extensos en este sector profesional.The increasing proportion of elderly citizens worldwide is leading to

Full Text Available Introduction. Generalised pustular psoriasis (GPP is regarded as a rare clinical subtype of psoriasis. The severity of GPP varies from a benign, chronic course to severe and widespread, life-threatening disease. Due to the uncommon nature of GPP, establishing treatment guidelines for this variant of psoriasis is challenging. Objective. To present the case of a patient with GPP with a short review of therapeutic approaches. Case report. Our patient was treated with standard methods such as acitretin, then cyclosporine and methotrexate as well as with biologic drug – infliximab. During the last and the most severe flare, combination therapy with systemic retinoid and PUVA (Re-PUVA was used. Conclusions. The treatment in GPP should be determined individually according to the severity of the disease, age, gender and comorbidities, as well as according to the physician’s experience with particular methods and their side effects. In addition, the availability of therapeutic options should be taken into consideration.

No epidemiological study has examined the clinical characteristics, including medication use, of patients with eosinophilic pustular folliculitis (EPF). To describe the clinical characteristics for EPF and to examine the factors associated with the effectiveness of oral indomethacin for EPF. A cross-sectional study was performed of patients with EPF who visited the dermatology departments of the 67 main teaching facilities in Japan. We documented the patient characteristics and examined factors associated with the effectiveness of oral indomethacin. A total of 145 patients with EPF were enrolled; 62.8% were prescribed oral indomethacin. A multivariable analysis revealed that female patients were more likely to exhibit complete response to oral indomethacin after adjustment for confounders (adjusted proportion ratio = 1.93, p = 0.04). Oral indomethacin has been accepted as a first-line treatment in EPF. Our results suggest that there is a sex difference in the treatment response to oral indomethacin. © 2014 S. Karger AG, Basel.

Dermatosis papulosa nigra (DPN) is a benign epithelial tumor that is common in dark-skinned people. Although the diagnosis is easily made on medical examination, DPN is characterized by a chronic and worsening course. Therefore, even if DPN is a benign disease, the lesions are unaesthetic and the therapeutic options are quite inefficient. A prospective study was carried out during a period of 24 months (January 2006 to December 2007) at the Department for Preventive Medicine for Migration, Tourism and Tropical Dermatology of San Gallicano Dermatological Institute in Rome. Among 58 patients, 41 (71%) were women and 17 (29%) were men. The mean age was 33.5 years (range, 8-45 years). One pediatric patient was observed. This study is the first in Italy that, in recent years, has observed an important growth of the migration. The classic female predominance, family predisposition, and photodistribution of the lesion were found. DPN is frequently associated with patient discomfort, therefore the education of patients to reduce self-treatment is important.

Improvement of Anti-TNF-α Antibody-Induced Palmoplantar Pustular Psoriasis Using a 308-nm Excimer Light

Full Text Available Anti-tumor necrosis factor (TNF-α antibody is utilized in the treatment of a variety of chronic inflammatory conditions, including psoriasis. However, it can induce paradoxical development and/or exacerbation of psoriasis in the course of anti-TNF-α antibody treatment, which is sometimes refractory to conventional treatments. Herein, we report a case of refractory palmoplantar pustular psoriasis induced by anti-TNF-α antibody treatment, which was improved by treatment with a 308-nm excimer light. The 308-nm excimer light has less long-term risks than narrow-band UVB. The 308-nm excimer light may be a good therapeutic option for refractory psoriatic skin lesions induced by anti-TNF-α antibody therapy because of localized side effects without systemic problems, short length of treatment and low cumulative dosages of UV light.

Although more than 300 cases of eosinophilic pustular folliculitis (EPF) have been reported to date, differences in clinicohistopathological findings among affected sites have not yet been evaluated. To evaluate differences in the clinical and histopathological features of facial and extrafacial EPF. Forty-six patients diagnosed with EPF were classified into those with facial and extrafacial disease according to the affected site. Clinical and histopathological characteristics were retrospectively compared, using all data available in the patient medical records. There were no significant between-group differences in subject ages at presentation, but a male predominance was observed in the extrafacial group. In addition, immunosuppression-associated type EPF was more common in the extrafacial group. Eruptions of plaques with an annular appearance were more common in the facial group. Histologically, perifollicular infiltration of eosinophils occurred more frequently in the facial group, whereas perivascular patterns occurred more frequently in the extrafacial group. Follicular mucinosis and exocytosis of inflammatory cells in the hair follicles were strongly associated with facial EPF. The clinical and histopathological characteristics of patients with facial and extrafacial EPF differ, suggesting the involvement of different pathogenic processes in the development of EPF at different sites. © 2013 British Association of Dermatologists.

Lipoff, Jules B; Mudgil, Adarsh V; Young, Saryna; Chu, Paul; Cohen, Steven R

2009-01-01

We describe a patient with acantholytic dermatosis of the crural folds (ADCF) that was misdiagnosed and treated as condyloma acuminata for 13 years. After many skin biopsies consistently showed epidermal acantholysis and negative human papillomavirus serotyping excluded condyloma acuminata, a diagnosis of ADCF was considered most likely. Acitretin effectively suppressed the symptomatic hyperkeratosis. Subsequent genetic testing revealed a deletion in the ATP2C1 gene that led us to conclude that this case of ADCF is probably a variant of familial benign chronic pemphigus (Hailey-Hailey disease).

Full Text Available Background: Juvenile plantar dermatosis (JPD, also known as “wet and dry foot syndrome,” is a skin disorder of the feet that commonly affects children from ages 3–14. JPD is frequently seen in children with eczema, but it is not a requirement for diagnosis. Forefoot eczema (FE is synonymous with JPD is a condition characterized by dry fissured dermatitis of the plantar surface of the feet. Aims: To study the clinical patterns of FE and its associated risk factors. Methods: Twenty-five patients were recorded in the study during the period from April 2013 to March 2014. Fungal scrapings, patch testing, and biopsy for histopathological examination were done wherever required. Results: In our study, the most common site affected was the plantar surface of the toes in 8 (32% patients. Hand involvement, with fissuring and soreness of the fingertips and palm, was seen in two patients (8%. Four patients (16% had a personal history of atopy whereas a family history of atopy was present in 3 (12%. Nine patients (36% had associated risk factors with reported aggravation of itching with plastic, rubber, or leather footwear, and with prolonged contact with water and detergents. Negative fungal scrapings and culture in all patients ruled out a dermatophyte infection. Patch testing with Indian Standard Series was performed in all patients and was positive in three. Conclusions: This study concluded FE as a distinctive dermatosis of the first and second decade, predominantly in males, with a multifactorial etiology and confirming the concept of FE as a barrier disease beyond eczema.

Case report of a pustular dermatitis outbreak in sheep: Clinical and food safety considerations

Full Text Available The objective of this report is to describe an outbreak of pustular dermatitis in a flock of about 200 sheep, its clinical evolution and food safety implications. The onset of the symptoms was sudden and the lesions spread very quickly from ewe to ewe, so that in about 3 days almost all of the lactating sheep were stricken. Pustules from 5 different animals, six milk samples, two cheese samples, teat cup samples from the milking machine and farmer’s hands were analysed. A pure culture of Staphylococcus aureus, producing staphylococcal enterotoxin (SE C, was isolated from pustules. Milk and cheese showed a contamination by coagulase positive staphylococci <15 and 30 colony forming units respectively and the absence of SE. Farmer’s hands and teat cups samples resulted negative for coagulase positive staphylococci. Therapy with daily topical medicaments was prescribed and a prophylactic intervention was suggested by the administration of an autovaccine. The low level of milk and cheese contamination and the absence of SE in cheese supported the decision to not advise the farmer to recall cheese produced with milk from affected animals.

Flame figures in linear IgA bullous dermatosis: a novel histopathologic finding.

Fulton, E; Jan, F; Zimarowski, M J

2017-11-15

Linear IgA bullous dermatosis (LABD) is an autoimmune subepidermal blistering disease usually with a neutrophil rich inflammatory infiltrate, and characterized by linear IgA deposition at the basement membrane zone (BMZ), and neutrophil predominant dermal inflammation. We report a case of LABD with numerous eosinophils and flame figure formation, a unique histopathologic finding not previously reported. A 69-year-old woman presented with a rapidly progressive, intensely pruritic rash over forearms, breasts, axillae, hips, and thighs. Thelesions were comprised of annular vesicles and bullae with hemorrhagic crusts and erosions. The clinical differential diagnosis included bullous pemphigoid(BP), LABD, and epidermolysis bullosa aquisita (EBA). A biopsy from a bullous plaque on the wrist revealed a subepidermal blister with neutrophils and numerous eosinophils with flame figure formation.Direct immunofluorescent (DIF) microscopy revealed linear deposition of IgA at the BMZ. Although unusual, the combined findings supported a diagnosis of LABD. Increased eosinophils may be associated with drug-induced LABD and may explain the numerous eosinophils in our case. It is important to be aware of this finding as the pathology may easily be misdiagnosed as BP, or possibly bullousWells syndrome. This case emphasizes that combined clinical, pathologic, and DIF findings are essential in the diagnosis of bullous dermatoses.

Limited information exists regarding juvenile generalized pustular psoriasis (GPP). We aim to determine the clinical profile and outcome of Malaysians with juvenile GPP. Review of hospital case notes on patients with juvenile GPP. Twenty-seven patients with juvenile GPP were identified. Female to male ratio was 1.4:1. The median age at onset of GPP was 6.5 years. Ten patients had prior psoriasis with a median pre-pustular duration of 2.7 years. Onset of GPP was earlier in patients without prior psoriasis (5.1 years vs. 12.0 years, P = 0.002). Precipitating factors identified included stress, upper respiratory tract infection, systemic steroid use, vaccination, and pregnancy. A positive family history of psoriasis and GPP was present in six and one patient(s), respectively. Twenty-one patients had acute, five annular, and one localized variant of GPP. Arthritis was present in 22.2%. Fever, leukocytosis, and transaminitis were mainly seen in patients with acute GPP at 80.9, 72.2, and 11.1%, respectively. Among 20 patients screened, eight carry IL36RN variants and one has CARD14 mutation. IL36RN-positive patients have more severe disease characterized by early onset, low prevalence of prior plaque psoriasis, high prevalence of systemic inflammation, and need for continuous long-term systemic therapy. Acitretin and cyclosporine were effective in aborting acute GPP in 100% of 16 and 66.7% of six patients treated, respectively. However, relapses were common. Only three of the 17 patients whose initial acute GPP was controlled with systemic agents were successfully weaned off treatment. Juvenile GPP is a chronic recalcitrant disease. IL36RN-positive patients have more severe disease. © 2017 The International Society of Dermatology.

Eosinophilic pustular folliculitis associated with hematological disorders: A report of two cases and review of Japanese literature.

Eosinophilic pustular folliculitis (EPF) occurs in patients with hematological disorders. However, clinical information about hematological disorder-associated EPF is scarce. We report two cases of EPF associated with mantle cell lymphoma and reviewed the available published work on Japanese cases. We identified a total of 23 Japanese cases, including the two cases reported here, who had hematological disorder-associated EPF. Fourteen cases were associated with treatment for hematological malignancies (transplantation-related EPF) and nine cases were associated with hematological malignancies themselves (hematological malignancy-related EPF). Although the skin eruption was clinically indistinguishable between the two subtypes, transplantation-related EPF occurred on the face and trunk of young and middle-aged men and women, whereas hematological malignancy-related EPF occurred mostly on the face of older men. Peripheral blood eosinophilia was more frequently observed in transplantation-related EPF. These observations suggest variations among patients with EPF associated with hematological disorders. © 2015 Japanese Dermatological Association.

Gao, Qian-Qian; Xi, Ming-Rong; Yao, Qiang

2013-01-01

Impetigo herpetiformis (IH) is a rare pustular dermatosis that typically occurs in pregnant women with unknown etiology. We report an 18-year-old primigravida who presented with IH at nearly 30 weeks' gestation and was the first patient reported in mainland China. The patient's condition deteriorated rapidly in spite of treatment with corticosteroids and antibiotics, so we decided to terminate the pregnancy by induction of labor. After vaginal delivery she developed fever and her skin lesions did not disappear naturally. Fortunately her symptoms were resolved with the treatment of antibiotics and acitretin, and at day 60 postpartum her skin lesions had completely disappeared. Although IH is associated with high mortality and morbidity in both fetus and mother, a better prognosis could be achieved with an immediate diagnosis and proper treatment. The etiology of IH needs to be further explored and the process of diagnosis and therapy should be standardized. Copyright © 2013 S. Karger AG, Basel.

Rosacea – new data on pathogenesis and treatment

Directory of Open Access Journals (Sweden)

Waldemar Placek

2016-10-01

Full Text Available Rosacea is a common dermatosis more prevalent in females, significantly impairing quality of life. Currently erythematous, papulo-pustular and phymatous subtypes are distinguished, which do not necessarily represent consecutive stages. Recent findings indicate in the pathogenesis of rosacea the role of the impaired innate immune system and vascular abnormalities. Additionally, the role of genetic and infectious factors is suggested. The therapy of rosacea is directed not only against inflammatory changes but also anti-parasitic. In topical treatment the most commonly used are metronidazole and azelaic acid. Other drugs are topical antibiotics, antiparasitic agents such as ivermectin and preparations directly influencing erythema. In more severe cases tetracyclines or macrolides are used, and in the most severe cases, isotretinoine. As ultraviolet light is a recognized trigger for rosacea, regular sunscreen use is necessary. Also, proper diet is indicated. Presently in the treatment of rosacea more and more techniques using different lights are employed.

2007-01-01

Background Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV) is a significant disease among domestic and wild cattle. The BHV-1 infection was first detected in Finland in 1970; presumably it was imported in 1968. The infection reappeared in the large-scale bulk-tank milk surveillances which started in 1990, and was eradicated in 1994. Our aim is to describe the epidemiology of this infection in Finland, and its eradication. Materials and methods The official sources of pertinent information, the legal basis for the disease control and the serological methods for the detection of the infection are described. Results and conclusion Ten AI bulls were found to be seropositive in 1970–1971. The total number of herds with BHV-1 antibody positive animals in the large-scale surveillance in 1990 and subsequent epidemiological investigations in 1991 was five, and the total number of seropositive animals was 90. The five herds formed three epidemiological units; semen of at least one bull seropositive in 1971 had been used in each unit. This remained the only plausible route of infection in each of the three units. Using the 'test and slaughter' approach and total stamping out in one herd the infection was eradicated in 1994.

Results and conclusion Ten AI bulls were found to be seropositive in 1970–1971. The total number of herds with BHV-1 antibody positive animals in the large-scale surveillance in 1990 and subsequent epidemiological investigations in 1991 was five, and the total number of seropositive animals was 90. The five herds formed three epidemiological units; semen of at least one bull seropositive in 1971 had been used in each unit. This remained the only plausible route of infection in each of the three units. Using the 'test and slaughter' approach and total stamping out in one herd the infection was eradicated in 1994.

In this study we present a patient with the sublamina densa type of linear IgA bullous dermatosis (LABD), with IgA autoantibodies reactive with the 290-kDa type VII collagen (the epidermolysis bullosa acquisita (EBA) antigen) and with immunoblotting of normal human dermal extracts. The clinical and histological features of the present case were compatible with those of LABD but quite different from those of EBA. Although EBA sera reacted with the bacterial fusion protein of the N-terminal globular (NC1) domain of type VII collagen, this patient's serum did not show reactivity. Furthermore, ultrastructural localization of target epitopes on the anchoring fibrils in this patient was considerably different from EBA. These results indicate that, whereas EBA antibodies react with the NC1 domain of type VII collagen, the epitope in this case is different from that of EBA (and is most likely on the central triple helical domain). This difference may be responsible for the clinical presentation in this patient being distinct from that of EBA.

Despite the increasing reliance on computers and the associated health risks, computer-related dermatoses remain under-represented in the literature. This term collectively refers to four groups of cutaneous pathologies: 1) allergic contact dermatitis from exposure to certain chemicals in computer accessories, 2) various friction-induced hand lesions resulting from prolonged computer use, 3) erythema ab igne from placement of the laptop on the skin, and 4) "screen dermatitis" from excessive exposure to visual display terminals (VDTs). Within this review we also present a case of a friction-induced lichenified dermatosis in the dominant wrist of a 24-year-old female that was caused by excessive use of her computer mouse. More importantly, we review the literature of all previously reported cases of computer-related dermatoses, so as to promote recognition and appropriate management by both patients and physicians.

Full Text Available Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV are diseases that affect cattle population of all breeds, categories and age. Both diseases, especially infectious bovine rhinotracheitis (IBR, poses severe health threat and causes major economic losses and is considered one of the “most costly” disease in cattle industry. The causal agent of the disease is a virus and any detection of IBR/IPV specific antibodies in non-vaccinated cattle, either in blood or milk, indicates that animal is infected and represents the source of infection. Countries with developed and intensive cattle breeding have been developed and implemented their national eradication programs to control IBR/IPV in accordance with international regulations. In this article, we outlined the needs and program for the eradication of IBR/IPV in the Republic of Serbia. The eradication program for IBR/IPV is an extensive process that requires systematic strategy involving different phases and activities. The eradication process from the moment of implementation until obtaining IBR/IPV-free status can last over several years and requires joint work and considerable financial resources that will be compansated with the elimination of IBR/IPV from the herd. This article gives an overview of all stages and activities regarding eradication of the disease and certification and maintaining of IBR/IPV-free herd status.

Ureaplasma diversum has been associated with various reproductive problems in cattle that include granular vulvovaginitis, weak calves, and abortion. This study was conducted in a beef herd situated in the Middle-West region of Brazil, and the objectives were to verify the presence of U. diversum and to elucidate its possible relationships with independent variables in this bovine herd population. A total of 134 vaginal mucous swabs were taken for polymerase chain reaction (PCR). Of these, 51 (38 %) were PCR positive for U. diversum. Of the 58 heifers with vulvovaginal lesions characterized by hyperemia, granulated lesions, and edema distributed throughout the vulvar mucosa, 37 (64 %) were U. diversum positive; of the 76 heifers without reproductive lesions, 14 (18 %) were U. diversum positive. All tested samples were negative for bovine herpesvirus 1 (BoHV-1). Multivariate logistic regression revealed that the following two variables were significantly associated with the presence of U. diversum: the presence of vulvar lesions (p = 0.001) and the presence of a progesterone (P4) device (p = 0.001). These findings indicate that U. diversum should be considered a pathogen that is associated with pustular vulvovaginitis in heifers from the Mato Grosso state and that additional studies of the risk factors associated with intravaginal P4 device transmission should be performed.

Tzanck smear is generally used for the diagnosis of the pemphigus group of autoimmune bullous diseases and mucocutaneous herpesvirus infections. There are only a few studies in the literature investigating its diagnostic value. We aimed to investigate Tzanck smear findings and to determine the diagnostic value of this test in moist (erosive, vesicular, bullous, and pustular) skin lesions. We also aimed to develop an algorithmic approach for the diagnosis of these types of skin lesions according to the Tzanck smear findings. Samples were stained with May-Grünwald-Giemsa and evaluated by the same dermatologist. In some patients, methylene blue and Gram staining or direct immunofluorescence examinations were additionally performed. In all of the study cases, after the evaluation of clinical and laboratory findings (including, when appropriate, potassium hydroxide examination; viral serology; bacterial and fungal cultures; histopathology; direct and indirect immunofluorescence; patch testing), the definite diagnosis was established. We also determined the sensitivity and the specificity of certain Tzanck smear findings. Tzanck smear was performed in a total of 400 patients with moist skin lesions. The sensitivities of multinucleated giant cells and acantholytic cells in herpetic infections, dyskeratotic acantholytic cells and cocci in bullous impetigo, pseudohyphae in candidiasis, acantholytic cells in pemphigus and more than 10 tadpole cells (magnification x100) in spongiotic dermatitis were 84.7%, 92%, 100%, 100%, and 81.5%, respectively. Because Tzanck smears were evaluated by the same dermatologist, no comment could be made regarding the interobserver reliability of this test and how the level of experience with this technique might affect the results. Also, the sensitivity and the specificity of Tzanck smear test findings for certain diseases could not be calculated because of an insufficient number of patients. The Tzanck smear test is an inexpensive, useful

Characterization of Pustular Mats and Related Rivularia-Rich Laminations in Oncoids From the Laguna Negra Lake (Argentina

Full Text Available Stromatolites are organo-sedimentary structures that represent some of the oldest records of the early biosphere on Earth. Cyanobacteria are considered as a main component of the microbial mats that are supposed to produce stromatolite-like structures. Understanding the role of cyanobacteria and associated microorganisms on the mineralization processes is critical to better understand what can be preserved in the laminated structure of stromatolites. Laguna Negra (Catamarca, Argentina, a high-altitude hypersaline lake where stromatolites are currently formed, is considered as an analog environment of early Earth. This study aimed at characterizing carbonate precipitation within microbial mats and associated oncoids in Laguna Negra. In particular, we focused on carbonated black pustular mats. By combining Confocal Laser Scanning Microscopy, Scanning Electron Microscopy, Laser Microdissection and Whole Genome Amplification, Cloning and Sanger sequencing, and Focused Ion Beam milling for Transmission Electron Microscopy, we showed that carbonate precipitation did not directly initiate on the sheaths of cyanobacterial Rivularia, which dominate in the mat. It occurred via organo-mineralization processes within a large EPS matrix excreted by the diverse microbial consortium associated with Rivularia where diatoms and anoxygenic phototrophic bacteria were particularly abundant. By structuring a large microbial consortium, Rivularia should then favor the formation of organic-rich laminations of carbonates that can be preserved in stromatolites. By using Fourier Transform Infrared spectroscopy and Synchrotron-based deep UV fluorescence imaging, we compared laminations rich in structures resembling Rivularia to putatively chemically-precipitated laminations in oncoids associated with the mats. We showed that they presented a different mineralogy jointly with a higher content in organic remnants, hence providing some criteria of biogenicity to be searched

Linear IgA bullous dermatosis (LABD) is a clinically and immunologically heterogeneous, subepidermal, autoimmune bullous disease (AIBD), for which the long-term evolution is poorly described. To investigate the clinical and immunological characteristics, follow-up and prognostic factors of adult idiopathic LABD. This retrospective study, conducted in our AIBD referral centre, included adults, diagnosed between 1995 and 2012, with idiopathic LABD, defined as pure or predominant IgA deposits by direct immunofluorescence. Clinical, histological and immunological findings were collected from charts. Standard histology was systematically reviewed, and indirect immunofluorescence (IIF) on salt-split skin (SSS) and immunoblots (IBs) on amniotic membrane extracts using anti-IgA secondary antibodies were performed, when biopsies and sera obtained at diagnosis were available. Prognostic factors for complete remission (CR) were identified using univariate and multivariate analyses. Of the 72 patients included (median age 54 years), 60% had mucous membrane (MM) involvement. IgA IIF on SSS was positive for 21 of 35 patients tested; 15 had epidermal and dermal labellings. Immunoelectron microscopy performed on the biopsies of 31 patients labelled lamina lucida (LL) (26%), lamina densa (23%), anchoring-fibril zone (AFz) (19%) and LL+AFz (23%). Of the 34 IgA IBs, 22 were positive, mostly for LAD-1/LABD97 (44%) and full-length BP180 (33%). The median follow-up was 39 months. Overall, 24 patients (36%) achieved sustained CR, 19 (29%) relapsed and 35% had chronic disease. CR was significantly associated with age > 70 years or no MM involvement. No prognostic immunological factor was identified. Patients with LABD who are < 70 years old and have MM involvement are at risk for chronic evolution. © 2017 British Association of Dermatologists.

Based on Molecular Profiling of Gene Expression, Palmoplantar Pustulosis and Palmoplantar Pustular Psoriasis Are Highly Related Diseases that Appear to Be Distinct from Psoriasis Vulgaris.

Full Text Available There is a controversy surrounding the existence of palmoplantar pustulosis (PPP and palmoplantar pustular psoriasis (PPPP as separate clinical entities or as variants of the same clinical entity. We used gene expression microarray to compare gene expression in PPP and PPPP.Skin biopsies from subjects with PPP (3, PPPP (6, psoriasis vulgaris (10 and acral skin from normal subjects (7 were analyzed using gene expression microarray. Principal component analysis showed that PPP and PPPP were different from psoriasis vulgaris and normal acral skin. However gene expression of PPP and PPPP clustered together and could not be used to differentiate PPP from PPPP. Gene-wise comparison between PPP and PPPP found no gene to be differentially expressed at a false discovery rate lower than 0.05. Surprisingly we found a higher expression of several genes involved in neural pathways (e.g. GPRIN and ADAM23 in PPP/PPPP as compared to psoriasis vulgaris and normal acral skin. Immunohistochemistry confirmed those findings and showed a keratinocyte localization for those proteins.PPP and PPPP could not be differentiated using gene expression microarray suggesting that they are not distinct clinical entities. Increased expression of GPRIN1, and ADAM23 in keratinocytes suggests that these proteins could be new therapeutic targets for PPP/PPPP.

Full Text Available Introduction: Neutrophilic dermatosis (ND is a heterogeneous group of diseases with various etiologies and clinical presentations. NDs may clinically present as papule, vesiculopustule, plaque, and nodule of the skin, but they all share the common feature of neutrophilic predominance in the skin. Histological examination of patients with suspected ND is a key step for making the proper diagnosis. Patients and Methods: The aim of this article was to investigate histopathological aspects of different NDs. We obtained our data from medical records of patients at Razi dermatology hospital, between 2012 and 2014. Thirty-eight biopsy records coded under the term of any ND, including Sweet's syndrome (SS, pyoderma gangrenosum (PG, skin lesions of Behcet's disease, neutrophilic drug eruption, amicrobial pustulosis of the folds, pustular vasculitis of the hands, and undetermined ND were recruited in our study. The specimens were evaluated regarding inflammatory reaction pattern, epidermal/adnexal changes, and dermal changes. Results: Most common NDs in our study were PG (42.1% followed by SS (21.1%. The most common pattern of inflammatory reaction was superficial perivascular and interstitial dermal inflammation in 44.7% of the patients. Exocytosis of neutrophils into epidermis, hair follicle, and eccrine gland was seen in 71%, 18.5%, and 28.9% of the specimens, respectively. Ulceration was only seen in ten PG specimens. Dermal fibrosis and vascular proliferation were reported in all PG patients. Conclusion: The prevalence of some histopathological findings in different types of ND was significantly different. These features seem helpful in distinguishing between different NDs.

An otherwise healthy, full-term neonate presented at day 15 of life to the pediatric emergency with generalized papulo-pustular rash for 2 d. This was finally diagnosed as bullous impetigo caused by Staphylococcus aureus (S. aureus). The skin lesions decreased significantly after starting antibiotic therapy and drainage of blister fluid. There was no recurrence of the lesions on follow-up. This case of generalized pustular eruption due to S. aureus in a neonate is reported, as it poses a diagnostic dilemma and can have serious consequences if left untreated.

A 33-year-old healthy Latina (from either Mexico or Central America) woman with Fitzpatrick type V skin complained of a 2-year history of progressive hyperpigmentation on the axillary folds, dorsal hands, upper neck spilling onto the jawline area, and lower abdomen. There was no preceding dermatitis. The lesions were asymptomatic. She did not use any prescription or over-the-counter drugs or any herbal supplements. She denied contact with any new substances and did not start any new activities. A full review of systems was negative. Physical examination revealed diffuse symmetric gray patches on the proximal arms radiating from the axillary folds with extension onto the trunk (Figure 1). This discoloration was also present on the dorsal hands (Figure 2), upper neck and jawline, and lower abdomen. The lesions were nonpalpable and without erythema. Thyroid function test results and morning cortisol levels were normal. Two adjacent 4-mm punch biopsies were performed on the right axillary skin, one consisted of unaffected skin and one of hyperpigmented skin. Figure 3 shows affected axillary skin with an interface dermatitis and significant pigment dropout. There was no evidence of depositional process of substances such as heavy metals, drugs, or tattoo. There was no evidence of an actinic process. Differential diagnosis included erythema dyschromicum perstans (EDP), fixed-drug reaction, or interface drug reaction. As the patient was not taking any medications, the overall clinical and histologic impression was most consistent with EDP. The patient was started on a low-potency topical steroid twice a day to the affected areas. In addition, because the patient was concerned about the cosmetic appearance of the hyperpigmentation, a 4% hydroquinone cream was started twice daily to the neck area.

Childhood psoriasis

Full Text Available Psoriasis is a common dermatosis in children with about one third of all patients having onset of disease in the first or second decade of life. A chronic disfiguring skin disease, such as psoriasis, in childhood is likely to have profound emotional and psychological effects, and hence requires special attention. Psoriasis in children has been reported to differ from that among adults being more frequently pruritic; plaque lesions are relatively thinner, softer, and less scaly; face and flexural involvement is common and guttate type is the characteristic presentation. Whether onset in childhood predicts a more severe form of psoriasis is a matter of controversy, it may cause significant morbidity particularly if it keeps relapsing. Most children have mild form of psoriasis which can be generally treated effectively with topical agents such as emollients, coal tar, corticosteroids, dithranol, calcipotriol etc. according to age and the sites affected. Narrow band UVB is the preferred form of phototherapy in children for moderate to severe disease or in patients not responding to topical therapy alone. Systemic therapies are reserved for more severe and extensive cases that cannot be controlled with topical treatment and/or phototherapy such as severe plaque type, unstable forms like erythrodermic and generalized pustular psoriasis and psoriatic arthritis. There are no controlled trials of systemic therapies in this age group, most experience being with retinoids and methotrexate with favorable results. Cyclosporine can be used as a short-term intermittent crisis management drug. There is an early promising experience with the use of biologics (etanercept and infliximab in childhood psoriasis. Systemic treatments as well as phototherapy have limited use in children due to cumulative dose effects of drugs, low acceptance, and risk of gonadal toxicity. More evidence-based data is needed about the effectiveness and long-term safety of topical

Impetigo herpetiformis (IH), or generalized pustular psoriasis of pregnancy, is an exceedingly rare, generalized pustular skin eruption occurring during pregnancy associated with hypovolemia, sepsis, hypocalcemia, and airway edema. Fetal outcomes are generally poor, and parturients with IH may present with emergent indications for cesarean delivery due to placental insufficiency. We present a case of IH in a 19-year-old G1P0 who underwent successful general anesthesia for cesarean delivery. Her case highlights the anesthetic implications for patients afflicted with this rare disease, including perioperative pain management, airway concerns, considerations for neuraxial anesthesia, and monitoring challenges.

The objective of the present study was to analyse the occurrence of dermatosis in individuals that had been exposed to cesium{sup 137} during the radioactive accident in Goiania, in 1987 and detect pre-cancerous dermatosis or those predictive of low immunity. The groups were evaluated according to the intensity of radiation they had been exposed to and then compared to a control group of people not exposed to radiation. The population exposed to the cesium{sup 137} was comprised of 109 people, who were divided into Groups I and II, according to the CNEN norms. In group I, 54 people with {<=} 20 rads exposure and/or radio lesion were included; in group II, 55 people with > 20 rads exposure were included, along with the children of group I individuals. This was a historic cohort study, that is, a retrospective study that lasted 9 years, extending from September of 1987 to August, 1996. The presence of the oncoprotein p-53 was studied in the radio lesions of 10 patients. There is no evidence of an increase in the incidence of dermatosis in the exposed groups, excepts for pyoderma in patients with radio lesions. The most frequent dermatosis were: pyoderma, pityriasis versicolor, scabies, dermatophytosis and seborrhoeic dermatitis. The results obtained were not statistically significant for the evaluation of dermatosis predictive of low immunity or precancerous lesions. The oncoprotein p-53 in individuals with radio lesion showed a 80% positivity rate and risk factor estimated in 8 times, for the test. It has proved to be useful because it represents one more option in terms of propaedeutic evaluation and suggests that one should pay close and continuous attention in order to better control the evolution of these individuals.

Full Text Available Introduction: Skin lesions may be of dermatological importance, affect appearance, and cause problems communicating with peers and may be especially more significant in childhood. Aim :Information on the prevalence of pediatric dermatoses in Western Turkey. This study was aimed to define the existing data. Material and methods : A cross-sectional study was conducted in Canakkale, Turkey, in September-December 2013. It involved 1,957 students from five randomly selected primary and secondary schools. Each student was interviewed for age, gender, and family history, and a dermatologic examination was performed by a dermatologist. Data were coded and analyzed. Results :Of the students, 79.9% revealed at least one dermatosis. The most common disease was benign neoplasms (76%, followed by pigmentary disorders (26.8%, and xerosis (5.8%. In primary schools, the acquired melanocytic nevus, hypopigmented macule, and xerosis; in secondary school the acne was statistically significantly more common. Acne and xerosis was more common in girls, and pityriasis alba was statistically more common in boys. Students who had at least one dermatosis were positively correlated with monthly income. Conclusions :In Turkish school age children, the prevalence of dermatosis is 79.9%. It may be due to not using preventive means for adequate protection from the sun and other environmental factors. Infectious dermatosis and atopic dermatitis are rare and it may depend on the adequacy of public health work.

A 16-year-old boy presented with a number of asymptomatic pigmented macules on the volar aspect of his index fingers. Dermoscopy of each macule revealed a parallel ridge pattern of homogenous reddish-brown pigment. We propose that these lesions were induced by repetitive trauma from a Sony PlayStation 3 (Sony Corporation, Tokyo, Japan) vibration feedback controller. The lesions completely resolved following abstinence from gaming over a number of weeks. Although the parallel ridge pattern is typically the hallmark for early acral lentiginous melanoma, it may be observed in a limited number of benign entities, including subcorneal haematoma.

The historical, clinical and histopathological features of three dogs with eosinophilic folliculitis and furunculosis are described. The disease was characterised by the rapid development of pruritic, papular, pustular and ulcerative lesions on the dorsum of the muzzle. Skin lesions were confined to the face in two cases. The third dog had more generalised pustular lesions. Skin biopsy specimens showed marked eosinophil infiltration particularly centred on pilosebaceous units. Dermal collagen necrosis was evident in two cases. Similar facial lesions have previously been described as 'nasal pyoderma'. The three dogs failed to respond to initial antibacterial therapy but showed a rapid clinical response when prednisolone was given orally at doses ranging from 1 to 2.2 mg/kg, in addition to the antibacterial therapy, suggesting that glucocorticoids are indicated for the treatment of eosinophilic folliculitis and furunculosis. The aetiology of the disease was not determined.

Full Text Available Background: We are reporting a series of interesting cases, which presented to us with psoriasiform lesions distributed over the acral regions of the body. The cases are unusual because they were resistant to conventional treatment modalities like topical corticosteroids, tacrolimus and oral methotrexate but showed significant improvement on oral zinc therapy. Materials and Methods: Ten patients with characteristic clinical features of distinctive hyperkeratotic plaque in the acral areas, who were resistant to treatment by different modalities including potent topical steroids and oral methotrexate, were included for detailed investigations. A proper history was taken and relevant laboratory investigations were done which included blood count, urine, liver function, renal function, hepatitis-C virus serology and serum zinc levels. Patients were followed up every 2 weeks. Histopathological examinations of the lesional tissue were done at baseline and after 6 weeks of therapy. Patients were given oral zinc daily and no other treatment during the 6 weeks course. Results: All our patients were non-reactive to hepatitis-C. Of the ten patients only one patient (10% showed low titer of serum zinc, another (10% showed higher zinc level, while the rest of the patients had normal zinc level. Five of our patients had chronic renal failure, one had Grave′s disease and the remaining had no associated systemic illness. Histopathology mostly showed hyperkeratosis, acanthosis, prominent granular layer, spongiosis and dermal infiltrate. After 6 weeks of follow up, all patients showed rapid and remarkable therapeutic response with zinc. Conclusions: We here report a series of patients, discernible because of their uniform clinical presentation of acral hypekeratotic plaques and in showing a noticeable response to zinc. Clinical, histopathological and laboratory investigations were done to rule out diseases of similar morphology including psoriasis, acral necrolytic erythema and lichen simplex chronicus. Authors understand that further studies with greater number cases and more detailed investigations are required to establish exact etio-pathogenesis and nomenclature of this distinct subset of patients.

Black brown hyperpigmentation of the mucosae, sun exposed skin, palmar creases and frictional sites (Addisonian pigmentation) is characteristic of Addison disease. However, it can also occur as a para neoplastic manifestation of tumours like bronchogenic carcinoma. Acquired ichthyosis starts later in life and can also be a para neoplastic presentation.We report a unique combination of para neoplastic Addisonian pigmentation and acquired ichthyosis as presenting features in a patient with undiagnosed multiple myeloma. To the best of our knowledge this combination of para neoplastic dermatosis has not been documented before in multiple myeloma. It is concluded that the presence of more than one suspicious dermatosis may be an indicator of being para neoplastic requiring necessary work-up. (author)

Disseminated cutaneous Herpes Simplex Virus-1 in a woman with rheumatoid arthritis receiving Infliximab: A case report

Full Text Available Abstract Introduction We present the case of a 49-year-old woman with a seronegative rheumatoid arthritis who developed pustular psoriasis whilst on etanercept and subsequently developed disseminated herpes simplex on infliximab. Case presentation Our patient presented with an inflammatory arthritis which failed to respond to both methotrexate and leflunomide, and sulphasalazine treatment led to side effects. She was started on etanercept but after 8 months of treatment developed scaly pustular lesions on her palms and soles typical of pustular psoriasis. Following the discontinuation of etanercept, our patient required high doses of oral prednisolone to control her inflammatory arthritis. A second biologic agent, infliximab, was introduced in addition to low-dose methotrexate and 15 mg of oral prednisolone. However, after just 3 infusions of infliximab, she was admitted to hospital with a fever, widespread itchy vesicular rash and worsening inflammatory arthritis. Fluid from skin vesicles examined by polymerase chain reaction showed Herpes Simplex Virus type 1. Blood cultures were negative and her chest X-ray was normal. Her infliximab was discontinued and she was started on acyclovir, 800 mg five times daily for 2 weeks. She made a good recovery with improvement in her skin within 48 hours. She continued for 2 months on a prophylactic dose of 400 mg bd. Her rheumatoid arthritis became increasingly active and a decision was made to introduce adalimumab alongside acyclovir. Acyclovir prophylaxis has been continued but the dose tapered so that she is taking only 200 mg of acyclovir on alternate days. There has been no recurrence of Herpes Simplex Virus lesions despite increasing adalimumab to 40 mg weekly 3 months after starting treatment. Conclusion We believe this to be the first reported case of widespread cutaneous Herpes Simplex Virus type 1 infection following treatment with infliximab. We discuss the clinical manifestations of Herpes

2012-11-15

Acute generalized exanthematous pustulosis (AGEP) is a clinical reaction pattern characterized by the rapid appearance of widespread sterile, nonfollicular pustules arising within edematous erythematous skin. This aseptic pustular eruption is commonly accompanied by leukocytosis and fever and usually follows recent administration of oral or parenteral drugs. We report two cases of terbinafine-induced AGEP in male patients. Both patients developed a generalized erythroderma with scaling and pruritic pustules 7 and 14 days following initiation of oral terbinafine. With immediate discontinuation of terbinafine and various treatment protocols, both patients demonstrated recovery followed by skin desquamation during the subsequent weeks. Terbinafine is the most frequently used systemic antimycotic and antifungal medication, reflecting its superior efficacy for dermatophyte infections. Despite the appealing drug profile, an awareness of terbinafine-induced AGEP is important given the 5 percent mortality associated with AGEP. Additionally, distinguishing the characteristics of AGEP from those associated with toxic epidermal necrolysis, Stevens-Johnson syndrome, and generalized pustular psoriasis allows for prompt dermatologic evaluation, accurate diagnosis, and appropriate treatment.

Bovine herpes virus 1 (BHV-1) is primarily associated with clinical syndromes such as rhinotracheitis, pustular vulvovaginitis and balanoposthitis, abortion, infertility, conjunctivitis and encephalitis in bovine species. The main sources of infection are the nasal exudates and the respiratory droplets, genital secretions, semen, fetal fluids and tissues. The BHV-1 virus can become latent following a primary infection with a field isolate or vaccination with an attenuated strain. The viral genomic DNA has been demonstrated in the sensory ganglia of the trigeminal nerve in infectious bovine rhinotracheitis (IBR) and in sacral spinal ganglia in pustular vulvovaginitis and balanoposthitis cases. BHV-1 infections can be diagnosed by detection of virus or virus components and antibody by serological tests or by detection of genomic DNA by polymerase chain reaction (PCR), nucleic acid hybridization and sequencing. Inactivated vaccines and modified live virus vaccines are used for prevention of BHV-1 infections in cattle; subunit vaccines and marker vaccines are under investigation.

2008-01-01

Full Text Available Background: Acne vulgaris is one of the most common skin disorders in youth especially during the puberty. Objective: This in vitro study was performed to determine the antibiotic resistance and sensitivity in acne vulgaris. Materials and Methods: Samples were collected from normal skin and nodulocystic and pustular skin lesions of one hundred youngsters (64 girls, 36 boys among college students in the age range of 18-24 years old. The specimens were cultured individually on blood agar and Muller-Hinton media. The cultures were then incubated under both aerobic and anaerobic conditions for 2 to 7 days. Bacteria were identified and their resistance to common antibiotics was evaluated according to the standard procedures. Results: In aerobic culture of pustular and nodulocystic skin lesions, Staphylococcus aureus was present in 41% of subjects, Staphylococcus epidermidis in 53% and Micrococcus spp in 45% of subjucts. In anaerobic bacterial culture of pustular and nodulocystic skin lesions, Staphylococcus aureus was present in 39%, Propionibacterium acne in 33% and Staphylococcus epidermidis in 21% of subjects. The results of present study revealed that clindamycin and erythromycin were the least effective antibiotics for Propionibacterium acne while tetracycline was the least effective for Staphylococcus aureus in vitro . A synergic effect of benzoyl peroxide, erythromycin or clindamycin was noticed. Rifampin was the most effective antibiotic in vitro . Conclusion: Our results showed that rifampin was the most sensitive antibiotic in vitro for acne vulgaris. To achieve a better treatment, a combination of rifampin with other antibiotics may be more efficient. We suggest in vivo studies for better evaluation and treatment of acne patients with rifampin.

Facial peeling skin syndrome: a case report and a brief review.

Science.gov (United States)

Janjua, Shahbaz Ahmad; Hussain, Ijaz; Khachemoune, Amor

2007-03-01

Peeling skin syndrome is an extremely rare genodermatosis of possible autosomal recessive inheritance, characterized by asymptomatic spontaneous exfoliation of the stratum corneum at a subcorneal or intracorneal level. It usually presents at birth or appears later in early childhood. The condition may be generalized or localized. Here we describe a case of localized continual skin peeling limited to the facial skin in a 6-month-old infant, with two other members of the family affected with the same condition. A few cases of localized skin peeling limited to the acral surfaces have been described in the literature, but a familial case of localized skin peeling limited to the facial skin has not been described before. We believe that our patient represents a new subtype of peeling skin syndrome, limited to the skin of the face.

Full Text Available The incidence of some skin diseases are increasing at adolescent and early adulthood period. The most frequent disease at this period is acne vulgaris whereas fungal diseases, dermatitis, dermatosis which are due to stress and other reasons, oral mucosal lesions and herpetic lesions of perioral region are also frequent. In this research we aim to determine the frequent dermatologic diseases of university students and 147 female, 74 male, a total of 221 students are included. We questioned the dermatologic complaints of students, then examined dermatologically in detail and registered ages, sexes, findings of the dermatological examination and dermatological diagnostic informations. As a result it is found out that the most frequent diseases are acne vulgaris (34.1%, allergic and pruritic dermatosis (16.6%, fungal diseases ( 13.0%, and eritamatous-squamous disease (8.3%.

Dermatitis herpetiformis (DH) is characterized by variable degrees of enteropathy and increased intestinal permeability. Zonulin, a regulator of tight junctions, seems to play a key role in the altered intestinal permeability that characterizes the early phase of celiac disease. Our aim was to assess both intestinal permeability and serum zonulin levels in a group of patients with DH having variable grades of enteropathy. We studied 18 DH patients diagnosed on the basis of characteristic immunoglobulin (Ig)A granular deposits in the dermal papillae of noninvolved skin. Results were compared with those of classic celiac patients, patients with linear IgA dermatosis, and healthy controls. According to Marsh's classification, 5 patients had no evidence of enteropathy (type 0), 4 patients had type II, 2 patients had type IIIb damage, and 7 patients had a more severe lesion (type IIIc). Intestinal permeability (lactulose/mannitol ratio [lac/man]) was abnormal in all patients with DH. Patients with more severe enteropathy had significantly greater permeability ( P zonulin concentration (enzyme-linked immunosorbent assay) for patients with DH was 2.1 +/- .3 ng/mg with 14 of 16 (87.5%) patients having abnormally increased values. In contrast, patients with linear IgA dermatosis had normal histology, normal intestinal permeability, and negative celiac serology. Increased intestinal permeability and zonulin up-regulation are common and concomitant findings among patients with DH, likely involved in pathogenesis. Increased permeability can be observed even in patients with no evidence of histologic damage in biopsy specimens. Patients with linear IgA dermatosis appear to be a distinct population with no evidence of gluten sensitivity.

Wood, Benjamin A; LeBoit, Philip E

2013-08-01

To study the clinical and pathological features of cases of apparent solar purpura, with attention to the recently described phenomenon of inflammatory changes within otherwise typical lesions. We studied 95 cases diagnosed as solar purpura and identified 10 cases (10.5%) in which significant neutrophilic inflammation was present, potentially simulating a leukocytoclastic vasculitis or neutrophilic dermatosis. An additional three cases were identified in subsequent routine practice. The clinical features, including follow-up for subsequent development of vasculitis and histological features were studied. In all cases the histological features were typical of solar purpura, with the exception of inflammatory changes, typically associated with clefting of elastotic stroma. Clinical follow-up information was available for all patients and none developed subsequent evidence of a cutaneous or systemic vasculitis or neutrophilic dermatosis. Inflammatory changes appear to be more frequent in solar purpura than is generally recognised. Awareness of this histological variation and correlation with the clinical findings and evolution is important in avoiding misdiagnosis.

Granulomatous Dermatitis as a Cutaneous Manifestation of Hematologic Disorders: The First Case Associated With Polycythemia Vera and a New Case Associated With Myelodysplasia.

2016-06-01

Granulomatous dermatitis has been associated with hematologic disorders, including the myelodysplastic syndromes. We describe the first case of granulomatous dermatitis associated with polycythemia vera, presenting as large erythematous nodules mimicking panniculitis. We also present the seventh case associated with myelodysplasia, with erythematous plaques on the face and neck, similar to a neutrophilic dermatosis. We consider it particularly interesting for dermatologists to be aware of this dermatosis as a nonspecific manifestation of various hematologic disorders. We suggest performing additional tests (complete blood count) to exclude the possibility that the skin manifestations are the initial sign of hematologic disease. Furthermore, we propose using the broader term, granulomatous dermatitis, to refer to these disorders as, although there are more reports of interstitial forms, cases with a more nodular presentation have also been published, and the importance of the diagnosis derives not from the subtype but from the relationship with an underlying disease.

Primary seborrhoea in English springer spaniels: a retrospective study of 14 cases.

Science.gov (United States)

Scott, D W; Miller, W H

1996-04-01

Primary seborrhoea was diagnosed in 14 English springer spaniels over a 17-year period. Seven of the dogs developed clinical signs by two years of age. The dermatosis began as a generalised non-pruritic dry scaling which gradually worsened. Some dogs remained in this dry (seborrhoea sicca) stage, but in most cases the dermatosis became greasy and inflamed (seborrhoea oleosa and seborrhoeic dermatitis). Eight of the dogs suffered from recurrent episodes of superficial or deep bacterial pyoderma. Histological findings in skin biopsy specimens included marked orthokeratotic hyperkeratosis of surface and infundibular epithelium, papillomatosis, parakeratotic capping of the papillae, and superficial perivascular dermatitis in which lymphocytes and mast cells were prominent. The dogs with seborrhoea sicca responded more satisfactorily to therapy with topical emollient-humectant agents or oral omega-3/omega-6 fatty acid supplementation. Dogs with seborrhoea oleosa and seborrhoeic dermatitis did not respond satisfactorily to topical therapy. One dog, however, responded well to etretinate and omega-3/omega-6 fatty acid administration. No dog was cured.

Full Text Available We are reporting a rare case of amyloidosis cutis dyschromica in a 41-year-old man. This is a rare form of primary cutaneous amyloidosis characterized by reticulate pigmentation with hypopigmented and hyperpigmented macules, onset in childhood, familial tendency in some, occasional mild itching and deposition of amyloid in the papillary dermis. Our case also had multiple bilaterally symmetrical hyperpigmented keratotic papules abutting the axillary vault resembling those seen in Dowling-Deogs disease. The other unusual feature in this patient was the strong family history of vitiligo, which we are unable to explain. We have also tried to explain the mechanism leading to the hyperpigmentation and hypopigmentation in amyloidosis cutis dyschromica.

Morbid condition involving cardio-vascular, broncho-pulmonary, digestive and neural lesions in children and young adults after dietary arsenic exposure

Energy Technology Data Exchange (ETDEWEB)

Zaldivar, R.

1980-02-01

An investigation on the relationship between dietary arsenic exposure and cardiovascular diseases was made. In Antofagasta Commune, northern Chile, since 1955 arsenic has polluted public drinking water. This environmental contamination is of geological origin. The concentration of arsenic in drinking water for the 1955 to 1970 period was 0.5980 ppM. In the period June 1970 to March 1972, the concentration decreased to 0.0815 ppM due to a water filtration plant which started operating in May 1970. Greater Santiago showed 0.00 ppM of arsenic in drinking water. Amongst 10 autopsied patients with chronic arsenical dermatosis from Antofagasta Commune, 9 showed marked fibrous intimal thickening of the arterial wall and/or restricted lumen of the left coronary artery, 2 of these 9 also exhibiting myocardial infarction. Of the 10 patients, 7 developed cardiomegaly, which was related to chronic exposure to dietary arsenic. Two series of patients with myocardial infarction under 40 years of age, one from Antofagasta Commune, the other from greater Santiago (not exposed to arsenic) were compared. The Yates corrected chi 2 value being 11.7776. The difference was statistically highly significant. In Antofagasta Commune, the number of cases which had myocardial infarction with chronic arsenical dermatosis were compared with the cases which showed, myocardial infarction without chronic arsenical dermatosis. The Yates corrected chi 2 value was 13.0395. A highly significant difference was detected. Children from the two cities were also compared. The number of cases with myocardial infarction showed a significant difference; Fisher's exact test yielded a P approximately equal to 0.004944, the Yates corrected chi 2 value being 20.7311. The number of children with systemic occlusive arterial disease from the two cities also exhibited a highly significant difference.

Full Text Available The poultry industry in Brazil as well as the domestic consumption and exportation of poultry have experienced significant growth. The Federal Inspection Service is responsible for the sanitary inspection of poultry slaughter, and it routinely records injuries or illnesses that have been identified in the Management Information System of the Federal Inspection Service (SIGSIF. The aim of this study was to evaluate the main causes of condemnation in poultry slaughterhouses registered in the Federal Inspection Service from data entered into the SIGSIF system from 2006 to 2011. The total rate of condemnations observed during this period was 5.99%, and the major causes were contamination (1.80%, contusion /traumatic injuries (1.57%, dermatosis (0.74% and cellulitis (0, 50%. Regional variations were observed in the occurrence of condemnations, and only in case of dermatosis a seasonal behavior was observed. The SIGSIF is an important source of information concerning the causes of condemnations in poultry slaughter and can be a useful tool for assessing the causes and proposing measures to prevent or mitigate risks.

Molecular Detection of Pseudogymnoascus destructans (Ascomycota: Pseudeurotiaceae) and Unidentified Fungal Dermatitides on Big Brown Bats ( Eptesicus fuscus ) Overwintering inside Buildings in Canada.

2016-10-01

Big brown bats ( Eptesicus fuscus ) overwintering outside the underground environment are not believed to play a role in the epidemiology of the disease white-nose syndrome (WNS), caused by the fungus Pseudogymnoascus destructans (Pd). Using quantitative real-time PCR (qPCR), we provide molecular evidence for Pd on four big brown bats overwintering in heated buildings in New Brunswick, Canada. Two of the affected individuals also had very mild, focal, pustular, fungal dermatitis identified microscopically. A third bat, which was qPCR Pd-negative, had similar fungal lesions. Despite determining that these fungal lesions were caused by a suspected ascomycete, the intralesional fungi were not confirmed to be Pd. These findings demonstrate that bats overwintering in heated buildings and other above-ground sites may have subclinical or preclinical WNS, or be contaminated with Pd, and could play a role in local dispersal of Pd. Our inability to determine if the ascomycetes causing pustular lesions were Pd highlights the need for ancillary diagnostic tests, such as in situ hybridization or immunohistochemistry, so that Pd can be detected directly within a lesion. As the host-pathogen relationship for Pd evolves, and where bat species are exposed to the fungus under varying temperature regimes, lesions may become less stereotypic and such tests could help define these changes.

Pavlovic, Sasha; Krunic, Aleksandar L; Bulj, Tanja K; Medenica, Maria M; Fong, Kenneth; Arita, Ken; McGrath, John A

2012-01-01

Acral peeling skin syndrome (APSS) is a rare, autosomal, recessive genodermatosis characterized by painless spontaneous exfoliation of the skin of the hands and feet at a subcorneal or intracorneal level. It usually presents at birth or appears later in childhood or early adulthood. Some cases result from mutations in the TGM5 gene that encodes transglutaminase 5, which has an important role in cross-linking cornified cell envelope proteins. We report a new APSS pedigree from Jordan that contains at least 10 affected family members, although sequencing of the TGM5 gene failed to disclose any pathogenic mutation(s). On the basis of probable consanguinity, we performed homozygosity mapping and identified areas of homozygosity on chromosomes 1, 6, 10, 13, and 16, although none of the intervals contained genes of clear relevance to cornification. APSS is a clinically and genetically heterogeneous disorder, and this Jordanian pedigree underscores the likelihood of still further heterogeneity. © 2011 Wiley Periodicals, Inc.

Pragya Ashok Nair

2017-01-01

Full Text Available Vulvar lichen sclerosus (VLS is a chronic inflammatory dermatosis characterized by ivory-white plaques or patches with glistening surface commonly affecting the vulva and anus. Common symptoms are irritation, soreness, dyspareunia, dysuria, and urinary or fecal incontinence. Anogenital lichen sclerosus (LS is characterized by porcelain-white atrophic plaques, which may become confluent extending around the vulval and perianal skin in a figure of eight configuration. Thinning and shrinkage of the genital area make coitus, urination, and defecation painful. LS is not uncommon in India and present as an itchy vulvar dermatosis which a gynecologist may mistake for candidal vulvovaginitis. There is often a delay in diagnosis of VLS due to its asymptomatic nature and lack of awareness in patients as well as physicians. Embarrassment of patients due to private nature of the disease and failure to examine the genital skin properly are the other reasons for delay in diagnosis. There is no curative treatment for LS. Various medications available only relieve the symptoms. Chronic nature of the disease affects the quality of life. Proper and regular follow-up is required as there are chances of the development of squamous cell carcinoma.

Using clobetasol propionate in the form of a shampoo for the treatment of patients suffering from psoriasis localized in the scalp area

Directory of Open Access Journals (Sweden)

A. L. Bakulev

2016-01-01

Full Text Available The study involved 80 adult psoriatic patients with scalp affections at the dermatosis progressing stage. The authors compared scalp psoriasis topical treatment options such as using 0.05% clobetasol propionate in the form of a shampoo, and successive administration of the 2% salicylic acid ointment and aforesaid short-term topical product in patients with vulgar or exudative dermatoses using dynamic scores such as mPASI, DLQI and itching intensity degree. It was demonstrated that 0.05% clobetasol propionate used in the form of a shampoo is characterized by a high efficacy and safety profile for patients with vulgar or exudative psoriasis of the scalp. At the same time, in case of exudative dermatosis successive topical treatment with the use of the 2% salicylic acid ointment and 0.05% clobetasol propionate in the form of a shampoo contributes to the clearance of psoriatic foci from accumulated scales and enables a potent topical corticosteroid such as clobetasol to efficiently reduce principal clinical symptoms of scalp psoriasis such as erythema, infiltration, exfoliation and itching. Using the clobetasol shampoo reduces the scalp itching intensity as the key psoriatic symptom preventing an isomorphic reaction as a result of foci traumatization related to scratching.

Full Text Available Multiple myeloma is a malignant plasma cell proliferative disorder that produces a monoclonal immunoglobulin protein. The skin involvement and the development of bullous disease are rarely seen features in multiple myeloma. We present a 55-year-old man with a longstanding, large, tense bullous eruption and hypertrophic scars over his body accompanied recently with weight loss and fatique. He had no response to the previous treatments, which included oral glucocorticoids and dapsone. Histologic examination of the lesions revealed subepidermal bullae, while no immunoflourescence staining was observed. In a further detailed labarotory examination, multiple myeloma was detected. After the treatment of multiple myeloma with chemotherapy, the lesions regressed. Patients with longstanding, recurrent, unusual bullous eruption should be investigated for the development of multiple myeloma.

Erysipeloid, a cutaneous infection with the gram-positive bacillus Erysipelothrix rhusiopathiae, is typically an occupational dermatosis seen in persons working with livestock or involved in commercial fishing (fishmongers). Other more-generalized forms of infection with this organism also exist, including a septic form usually associated with endocarditis. Many infections may be self-limited. They have rarely been reported in children or in immunocompromised patients. This microbe is sensitive to many mainstream antibiotic agents. © 2012 Wiley Periodicals, Inc.

Full Text Available Chronic kidney disease causes skin changes which may sometimes be the first sign of kidney failure. Specific skin changes include acquired perforating dermatosis, porphyria cutanea tarda, pseudoporphyria, calcinosis and nephrogenic systemic fibrosis. The majority of patients present with cutaneous manifestations which are classified as non-specific, including xerosis, pruritus, pigmentation disturbances, nail plate abnormalities, uraemic frost and gynaecomastia. Treatment improving kidney function (dialysis therapy or kidney transplantation also leads to the resolution of skin lesions.

"Morgellons disease" has been a controversial topic in the history of psychodermatology. The most consensual scientific opinion is that it is a primary psychiatric disorder, particularly, a delusional disorder, although others were also pointed out. Some authors have suggested that it may correspond to a common dermatosis with secondary psychopathology. The Morgellons Research Foundation has advocated that it is "an emerging infectious" entity. This paper intends to critically review the main ideas and controversies, since its first description.

Friedman, Paula; Sabban, Emilia Cohen; Marcucci, Carolina; Peralta, Rosario; Cabo, Horacio

2015-01-01

Lichen planus (LP) is a papulosquamous dermatosis that involves the skin, scalp, nails and mucous membranes. Although its pathogenesis is still unknown, there is evidence that an imbalance of immunologic cellular reactivity plays an important role. Histopathologic examination reveals characteristic interface dermatitis. Dermoscopy is a non-invasive tool, useful in the assessment of inflammatory dermatoses, such as lichen planus. In this paper we describe the dermoscopic findings of different variants of LP (ungual, cutaneous, planopilaris, pigmentosus). PMID:26693092

There is no standard definition regarding the severity of psoriasis, and a number of factors should be considered, including the extent and stability of skin disease, involvement of joints, response to treatment, and impact on quality of life. Erythrodermic psoriasis and pustular psoriasis are severe conditions and the patient may be systemically unwell and febrile. NICE recommends that four key areas should be evaluated and recorded when assessing patients: severity, using the static Physician's Global Assessment (sPGA); disease impact on physical, psychological and social wellbeing using the Dermatology Life Quality Index (DLQI); the presence of psoriatic arthritis; and comorbidities. Ideally, patients should be assessed annually for psoriatic arthritis: the Psoriasis Epidemiology Screening Tool is a validated tool to screen for psoriatic arthritis in primary and secondary care. Patients with severe psoriasis should undergo cardiovascular risk assessment at presentation and every five years, or more frequently if indicated. Referral to secondary care should be made for patients with any type of psoriasis with poor response to topical therapy (after 2 or 3 months according to SIGN) and for extensive psoriasis. Cases where the psoriasis is having a significant physical or psychological impact on an individual's quality of life warrant early referral, as do those where the diagnosis is uncertain. Patients with generalised pustular psoriasis or erythroderma should be referred urgently for same-day specialist input. Patients with acute guttate psoriasis who may require phototherapy should also be referred. Children and adolescents with any type of psoriasis should be referred to a specialist at initial presentation.

Skin and joint manifestations are part of the clinical spectrum of many disorders. Well-known associations include psoriatic arthritis and arthritis associated with autoimmune connective tissue diseases. This review focuses on less common associations where skin lesions can provide easily accessible and valuable diagnostic clues, and directly lead to the specific diagnosis or limit the list of possibilities. This may also affect health care resources as diagnostic tests are often low-specific, highly expensive and poorly available. This group of diseases can be divided into two subsets, based on the presence/absence of fever, and then further classified according to elementary skin lesions (macular, urticarial, maculo-papular, vesico-bullous, pustular, petechial and nodular). In most instances joint involvement occurs as peripheral migrating polyarthritis. Erythematosus macular or urticarial rashes occur in most febrile disorders such as monogenic autoinflammatory syndromes, Schnitzler's syndrome, Still's disease and rheumatic fever and afebrile diseases as urticarial vasculitis. Pustular rash may be observed in chronic recurrent multifocal osteomyelitis (CRMO) and pyogenic arthritis with pyoderma gangrenosum and acne (PAPA) syndrome (both febrile) as well as in Behcet's disease and Synovitis, acne, pustulosis, hyperostosis and osteitis syndrome (both non-febrile). Papular lesions are typical of secondary syphilis, sarcoidosis, interstitial granulomatous dermatitis, papular petechial of cutaneous small-vessel vasculitis and nodular lesions of polyarteritis nodosa and multicentric reticulohistiocytosis all of which are afebrile. Differential diagnosis includes infections and drug reactions which may mimic several of these conditions. To biopsy the right skin lesion at the right time it is essential to obtain relevant histological information. © 2013 European Academy of Dermatology and Venereology.

Seven cases of severe candida infection in heroin addicts are reported. The principal features of this condition which arose in 1980, apparently due to a particular quality of heroin, are described, Candida albicans was the only pathogenic agent isolated from mainly scalp nodular and pustular lesions. These cutaneous lesions were associated in half the cases with ocular lesions, which sometimes had a poor prognosis despite active therapy. Osteo-articular complications were less common. Ketoconazole therapy alone gave good results in this series. The precise reasons for this dissemination of Candida albicans and for these localisations are still not clearly understood.

Full Text Available The application of food-specific IgG antibody detection in allergy dermatoses was explored. 181 patients with allergy dermatoses were diagnosed from January to September 2014 and 20 healthy subjects were selected. Fourteen kinds of food-specific IgG antibodies were detected by ELISA method among all the subjects. The positive rates of IgG antibody of the patient group and the healthy group were respectively 65.2% and 5.0%. The positive rates of IgG antibody of egg, milk, shrimp and crab took a large proportion in three groups of patients with three kinds of allergy dermatoses of urticaria, eczema and allergic dermatitis, the proportion of which was respectively 70.2%, 77.8% and 71.7%. Among urticaria and allergic dermatitis patients with positive antibody, the positive rate of children was significantly higher than that of adults (p0.05. Allergy dermatoses are closely related to food-specific IgG antibodies, and the allergy dermatoses patients have a high incidence rate of food intolerance; detecting IgG antibody in the serum of patients is of great significance for the diagnosis and treatment of allergy dermatoses.

Full Text Available Psoriasis is a chronic inflammatory condition with variable changes on the skin and nails, sometimes associated with osteoarticular manifestations characterizing the psoriatic arthritis. This arthritis may precede, follow, or be concomitant with the skin lesions of psoriasis. Unsuspected psoriatic arthritis may be misdiagnosed by other seronegative spondyloarthritis, mainly in primary care attention, and ominous outcomes are related to late and inadequate management. Therefore, diagnostic exercises with base on significant clinical and radiological images might contribute to enhance the suspicion index about these challenging conditions.

2018-03-01

Impetigo is a bacterial infection of the superficial layer of the epidermis with crusting or bullae caused by Streptococcus spp., Staphylococcus spp., or both. A 14-yr-old red-tailed monkey ( Cercopithecus ascanius) presented with recurrent scabbing and ulceration under the nares over an 8-yr period. Repeated cultures and biopsy samples led to a presumptive diagnosis of impetigo, later confirmed on necropsy. Multiple antibiotic regimens were employed with varying success during multiple episodes, while lesions resolved on their own at other times. This condition has not been previously reported in a nonhuman primate, although it is not uncommon in humans.

Acute generalized exanthematous pustulosis (AGEP) is a severe adverse cutaneous reaction characterized by an acute episode of sterile pustules over erythematous-edematous skin. The main triggering drugs are antibiotics, mainly beta-lactam and macrolides. Non-steroid anti-inflammatory drugs may rarely be responsible. We describe a case of a woman with AGEP, who presented with generalized pustulosis lesions after the use of piroxicam for renal colic. The diagnosis was confirmed by the clinical and histological correlations and the dermatosis resolved after withdrawal of the drug.

Acneiform Eruption and Other Dermatologic Side Effects Induced by Targeted Cancer Therapy: A Retrospective Analysis

Kurtuluş Didem Yazganoğlu

2012-06-01

Full Text Available Background and Design: Epidermal growth factor receptor (EGFR inhibitors may cause different adverse cutaneous reactions including acneiform (pustular, papulopustular eruption. Rarely, other specific targeted cancer therapy agents may cause similar pustular eruptions. The aim of this study was to evaluate the adverse skin reactions, mainly acneiform eruptions caused by these chemotherapeutic agents. Material and Methods: We retrospectively analyzed the data of 23 patients who developed acneiform eruption due to chemotherapeutic agents between May 2007 and April 2011. The drugs causing acneiform eruption, clinical features of eruption, other associated dermatologic adverse reactions and the treatment modalities used for the acneiform reaction were noted. Results: EGFR inhibitors such as erlotinib and cetuximab were the main drugs causing acneiform eruption in 21 patients. Everolimus and bevacizumab in combination with irinotecan were responsible in two patients. The eruption occurred on the face in all patients. The trunk, neck and the scalp were other affected body parts in some patients. The periorbital area on the face was generally spared. Xerosis and paronychia were the main associated adverse cutaneous reactions. Trichomegaly was another finding in two patients. The patients, who could have been followed, responded to topical or systemic antibiotics, or some medications for acne vulgaris/rosacea. Chemotherapy could be continued in all patients. Conclusion: Dermatologists need to know the specific eruptions occurring with chemotherapy drugs, especially EGFR inhibitors in order to develop the best approach without discontinuation of cancer therapy. Acneiform eruptions due to chemotherapeutics are most commonly seen on the face sparing periorbital area. Other reactions including mainly xerosis, paronychia and trichomegaly can also occur.

2013-10-01

A 27-year-old male patient who has used oral terbinafine for two weeks was admitted to our outpatient clinic for non-follicular millimetric pustules on erythematous and edematous different-sized plaques on his trunk and flexural areas. He was diagnosed with acute generalized exanthematous pustulosis (AGEP) because of terbinafine use in the light of history, clinical and histopathological findings. An AGEP is a rare and severe pustular reaction usually triggered by systemic drug intake. Approximately, 2.3% of the patients having oral terbinafine have been reported to develop cutaneous adverse effects. Although terbinafine is a commonly used medicine, it must be considered that it may cause severe adverse reactions.

Sweet's syndrome in association with common variable immunodeficiency.

2009-03-01

Sweet\\'s syndrome (SS), a rare reactive neutrophilic dermatosis, has been reported to occur in association with a variety of systemic disorders, categorized by von den Diesch into idiopathic, paraneoplastic, pregnancy and parainflammatory subgroups. The parainflammatory group has been well defined, and includes a wide spectrum of infectious triggers and disorders of immune dysregulation. To date, however, no cases of SS have been described in the context of common variable immunodeficiency (CVID). We report a case of paediatric-onset SS, previously reported as idiopathic, with a subsequent diagnosis of CVID.

Palmoplantar pustulosis (PPP) is a refractory, nonbacterial impetigo confined to the palms and soles. Its pathogenesis is still obscure, but it may be associated with the large eccrine sweat glands and pores of palmoplantar skin. PPP is considered to be a localized pustular psoriasis. Interleukin (IL)-8, IL-36γ and IL-36Ra play important roles in the pathogenesis of pustular psoriasis, but their role in PPP is unclear. To evaluate IL-8, IL-36γ and IL-36Ra expression in PPP, and their relationship with acrosyringia and pustule formation. mRNA expression was quantified in skin samples from patients with PPP (n = 7), patients with psoriasis vulgaris (PSV; n = 8) and healthy controls (HCs) (n = 6) by reverse-transcription-real-time PCR. Protein expression was characterized by immunohistochemistry (PPP, n = 17; PSV, n = 14; HCs, n = 12). Sweat ducts, including acrosyringia, were stained for epithelial membrane antigen (EMA). IL-8 mRNA and protein were markedly increased in PPP lesions compared with PSV lesions or HC skin. IL-36γ mRNA and protein were significantly more abundant in PPP lesions than in HC skin. IL-36Ra mRNA was significantly overexpressed in PPP lesions compared with HC skin, but there was no difference in IL-36Ra protein between PPP, PSV and HCs. IL-8 was abundantly expressed by neutrophils in PPP pustules, while IL36Ra was localized in the keratinocytes of PPP, PSV and HC skin. IL-36γ and EMA were colocalized in cells surrounding PPP pustules, and IL-36γ was also expressed in sweat duct cells in the dermis. IL-8, IL-36γ and IL-36Ra are overexpressed in PPP lesions. IL-8, IL-36γ and acrosyringia, rather than IL-36Ra, are associated with pustule formation in PPP. © 2018 British Association of Dermatologists.

Full Text Available This study was undertaken to identify occupation related skin problems among hotel workers. One thousand three hindered and ninety employees of a chain of vegetarian hotels were examined. Of the 273 people working in the kitchen, 206 (75.4% had dermatosis related to work. The Kitchen workers were classified according to the type of work they routinely performed. Forty eight out of the 63 (76.1% cooks who were involved in stirring had callosity at sites of contact with ladle and 28 of the40 (70% cooks who were involved in frying had pigmentation and scars due to contact with hot oil and water. All the onion peelers had staining and fissuring of the palmer aspect of the fingers. Thirty two of the 46(69.5% vegetable cutters had callosity on the palm at areas of contact with knife. Poori markers had pigmentation and callosity of knuckles due to pressing the dough with their knuckles. Nine of the 12 (66% rice cleaners had chapping of nails. Seven of the 12 (58.3% paratha markers had erythema of palm due to contact with hot tava. Tandoori experts had singing of hair over right forearm. Two workers (0.73% had pigmentation of the face probably due to prolonged exposure to heat. Two of the16 (12.5% grinders had paronychia and onychomycosis due to constant contact with water and dough. Nine of the 15 (60% coconut graters had callosities of the palms. We conclude the minor occupational dermatosis is prevalent among kitchen workers employed in hotels

Full Text Available Importance: Golimumab is a human monoclonal antibody, used for rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis. Adverse reactions are increasing with this class of medication (tumor necrosis factor α inhibitors. Observations: The authors present a case of a female patient who presented with psoriasis pustulosa after the use of golimumab for rheumatoid arthritis. Conclusions and Relevance: Paradoxically, in this case, golimumab, which is used for psoriasis, induced the pustular form of this disease. We are observing an increasing number of patients who develop collateral effects with tumor necrosis factor α inhibitors, and the understanding of the mechanism of action and how these adverse reactions occur may contribute to avoid these sometimes severe situations.

The authors present an unusual case of an acute swelling of the lower lip and septicemia in a 35-year-old, recent immigrant male arriving from India. The patient presented in our emergency department with a 48-hour history of a worsening, painful swelling of the lower lip. On presentation, he was pyrexial and the lip was found to be acutely inflamed with honey-colored crusting, pustular lesions, and induration . A diagnosis of impetigo leading to necrosis of the lip was established, a rare phenomenon potentially resulting in significant tissue destruction. Appropriate medical management achieved a good outcome and prevented disabling tissue loss of the orofacial region. Copyright © 2012 Elsevier Inc. All rights reserved.

Pemphigus foliaceus (PF) is a life-threatening autoimmune blistering skin disease caused by pathogenic IgG autoantibodies against desmoglein 1 (dg1), a desmosomal cadherin-type adhesion glycoprotein. Using lectins and glycosidases, we have shown that dg1 displays an N-glycosylation pattern of the complex triantennary type. We have found that lectins and glycosidases interfere with N-bound sugar residues on the amino-terminal ectodomain of dg1 and completely abolish, in vitro, the antigenicity of dg1 in most of the patients' sera. Moreover, in an ex vivo model using punch biopsies from normal human skin, we demonstrate that preincubation of the epidermis in wheat germ agglutinin (WGA) prevents PF autoantibody binding, acantholysis, and subcorneal blistering. In addition, we show that topical treatment with WGA inhibits PF autoantibody binding to keratinocytes in both newborn BALB/c mice and in organotypic human epidermis grafted onto the back of SCID mice. The epidermis of these pretreated animals displays a regular morphology, whereas control animals develop the immunopathologic phenotype of PF. These findings suggest that WGA may interfere with autoantibody binding to dg1, preventing experimental PF without affecting the adhesive function of dg1. Our observations may provide a new approach to the therapy of PF.

Fatima Bello

2012-01-01

Full Text Available Background. Bullosis diabeticorum is a distinct, spontaneous, noninflammatory, and blistering condition of acral skin that is unique to diabetics. It is rare. Exact aetiopathogenesis is not known, but many attributed peripheral neuropathy as a potent risk factor, others hypothesized the role of trauma, UV light, and nephropathy. Aim. To present cases of bullosis diabeticorum following long-distance journeys by road. Methods. History and physical examinations were done on 2 diabetics who presented with bilateral feet bullae following a long journey. Biopsy of a circumferential area of the bullae including adjoining apparently normal skin was done. Results. Features of peripheral neuropathy were noted. One developed digital gangrene without features of peripheral vascular disease. Culture of aspirate from a bullae yielded Staphylococcus aureus. Tissue biopsy showed hyperkeratotic focally acanthotic pigmented epidermis with subcorneal separation of the granular layer of the epidermis by aggregates of viable and nonviable polymorphs and lymphocytes. There is mild acantholysis of the epidermis, and a fibrocollagenous dermis which is moderately infiltrated by lymphocytes. Conclusion. Long journeys by road is a strong factor in the aetiopathogenesis of bullosis diabeticorum on a background of peripheral neuropathy. Diabetics especially those with peripheral neuropathy should be cautious while traveling long journeys by road.

Full Text Available Acanthosis nigricans (AN is a dermatosis characterized by velvety, papillomatous, brownish-black, hyperkeratotic plaques, typically on the intertriginous surfaces and neck. The majority (80% of AN occurs idiopathically or in benign conditions such as endocrinopathies like diabetes mellitus, polycystic ovary syndrome; metabolic syndrome and/or heritable disease. Malignancy-associated AN is rare. AN may rarely be associated with autoimmune diseases including systemic lupus erythematosus, due to antibodies to the insulin receptor, so-called type B insulin resistance. Here we report a case of AN in a case of diffuse progressive systemic sclerosis without evidence of insulin resistance.

Children are traveling to regions of the world that could pose a risk of acquiring diseases such as malaria, dermatosis, and infectious diarrhea. Most of these can be prevented by modifying high-risk behaviors or through the use of medications. Many of these same regions are endemic with diseases that are preventable through vaccination. Clinicians must be able to effectively prepare their pediatric-age travelers for international travel. Preventive education, prophylactic and self-treating medications, and vaccinations are all important components of this preparation. Familiarity with the use of travel vaccines is imperative.

2005-02-01

Localized scleroderma or morphea usually appears as flat or depressed lesions. We report 3 cases of morphea with atypical appearance, alternating pigmented and depigmented patches with nodules or sclerous bands, occurring in adult men. The occurrence of nodular elements on generalized or localized scleroderma, although rare, was first reported in the literature by Addisson in 1884. These nodules usually appear during evolution. These scleroderma are then described as being keloidal or nodular. We report 3 cases of nodules on localized scleroderma which appeared at the beginning of the dermatosis and where the scleroderma had a similar unusual irregularly pigmented appearance.

2005-01-01

Peeling skin syndrome is a rare dermatosis characterized by spontaneous and painless peeling of the skin. The authors report two patients with history of spontaneous, asymptomatic, and noninflammatory peeling skin of the acral surfaces after soaking in water. On light microscopy, blisters were located in the mid layers of the stratum corneum, above the granular layer. Ultrastructural examination revealed increased intercellular lipids and abnormal, "moth-eaten," keratohyalin granules, but the authors were unable to determine whether the separation initiated within the horny cells or between adjacent cells. These patients represented a localized variant of peeling skin syndrome.

Full Text Available Gonococcus typically affects the mucosal surfaces but in rare cases can spread to bloodstream causing disseminated gonococcal infection (DGI. The usual presentation of DGI is rash, polyarthralgia, and tenosynovitis. We present the case of a 23-year-old female who presented to our hospital with pustular rash and tenosynovitis of hand and was sent home on Augmentin. Her symptoms worsened despite treatment and she presented back to the ED. On investigation, she was found to have DGI and was appropriately treated. DGI should be kept in mind in sexually active youngsters who have only one or two features of the classic triad of rash, tenosynovitis, and arthritis. Timely management and appropriate treatment of DGI is very important to avoid complications and morbidity.

Acute generalised exanthematous pustulosis (AGEP) is a rare toxicoderma characterised by an acute onset rash, with many sterile pustules on the surface, high fever and increased acute phase reactants. We report the case of a patient who presented to the dermatology department with an AGEP and polyarthritis, in which a novel CARD14 mutation was identified. The pathophysiological mechanism of AGEP remains unclear, although mutations in the IL36RN gene have been identified in a small subset of AGEP patients. Similarly, mutations in the CARD14 gene have been linked to pustular types of psoriasis and familiar cases of pityriasis rubra pilaris; however, there are no reports associating mutations in the CARD14 gene with AGEP. © 2017 The Australasian College of Dermatologists.

Full Text Available It has been defined that coeliac disease is associated with most of the autoimmune diseases including psoriasis and vitiligo. Here, a 26-year-old woman who was diagnosed palmoplantar pustular psoriasis and already had coeliac disease and vitiligo is reported. According to our opinions, this is the first report describing the development of these three disorders in one patient, even though vitiligo, psoriasis and coeliac disease are common disorders, and the coexistence of the two of them has been previously reported in the literature. This case has been presented to emphasize the importance of considering and inquiring the possible coeliac disease in chronic and autoimmune dermatoses, although psoriasis and vitiligo may have coincidental associations with coeliac disease.

Cryotherapy usage to treat plantar warts

Treating dermatosis with liquid nitrogen as cryogen (substance generating cold) allows cellular destruction in more than 5 mm depth, making it indispensable to use it treating cutaneous cancers; besides that, it is cheap, easy to conserve and manage, and it is not considered flammable or toxic. Its applying retains the growth factor inside the injury, the collagen is not damaged as it is in burning by hot, there is not almost injury contraction, the perineurium is not altered, and when the tissue necrosis takes place, it retains tissue necrosis factor, helping to increase the necrosis of tissues. Taking into account the high incidence of dermatosis that can be treated with cryogen, in our consultation; we decided to generalize this treatment at the Provincial Interior Ministry Clinic. Plantar warts represent a big percent, limiting our patients in developing their working activities. This cutaneous viral disease is favored by the patients' systemic immunodepressions, hyperhidrosis and podalic disturbances. We selected the patients assisting to our extern al consultation with plantar wart clinical diagnosis in the period from September 2006 to September 2007. They signed an act of informed consent where the possible side effects are explained. Liquid nitrogen was applied with cotton applicators once a week after mechanical reduction. We made a clinical evolving evaluation fortnightly during the treatment, according to the elements and clinical characteristics referred by the patient, and proved by the physical examination carried out by the main investigator, because of the likelihood of short and long time side effects. This investigation demonstrated that cryotherapy is efficacious in treating plantar warts, since all the patients were healed in a short time period, most of them without side effects

A number of studies argue in favour of an important role of microbial colonization, in particular of Staphylococcus aureus, in triggering atopic dermatitis (AD) flare-up and psoriasis, in particular through the superantigenic properties of toxins generated by S. aureus. The aim of this study was to assess the efficacy of a 3-week Avène hydrotherapy on the skin surface of patients suffering from psoriasis or atopic dermatitis. Skin samples were taken from healthy subjects or atopic (n = 18) or psoriatic patients (n = 39) undergoing hydrotherapy at Avène at the beginning (D0) and the end of treatment (D18). The severity of the dermatosis was evaluated according to SCORing Atopic Dermatitis (SCORAD) or Psoriasis Area Severity Index (PASI) scores at D0 and D18. Marker of inflammation interleukin 8 (IL-8), S. aureus colonization (protein A) and enterotoxins were assessed in skin samples using RT-PCR. At D0, significant differences were observed between healthy subjects and atopic or psoriatic patients in all the parameters evaluated (IL-8, protein A). At the end of the hydrotherapy, a significant decrease in SCORAD was associated with a significant reduction of IL-8, S. aureus colonization and enterotoxin D in patients with atopic dermatitis. Similarly, a significant decrease in PASI was associated with a significant reduction of IL-8, S. aureus colonization and enterotoxin N in patients with psoriasis. This study demonstrates the positive effects of Avène hydrotherapy on the skin of patients suffering from chronic dermatosis, with decreased inflammation and reduced colonization by S. aureus. © 2010 The Authors.

Full Text Available Bullous dermatoses are the diseases characterized by vesication and erosion of skin and/or mucos coats, production of autoantibodies against the structural components of epidermis and/or derma. The most frequent diseases of these disorders are pemphigus, bullous pemphigoid, dermatitis herpetiformis, beningn familial chronic pemphigus (Gougerot Hailey-Hailey disease.Diagnostics of bullous dermatoses is based on assessement of clinical signs, results of cytological and histological studies and immunological tests. However none of the current diagnostic methods allows to reveal bullous dermatosis severally and with absolute certainty. Consequently it is necessary to perform wide range of clinical and laboratory tests for early diagnosis and treatment order.

Lichens striatus (LS) is an acquired, self-limiting inflammatory dermatosis that follows the lines of Blaschko. The etiology of the eruption is unknown, but several theories have been proposed with focus on environmental factors, viral infection, cutaneous injury, hypersensitivity, and genetic predisposition. We describe a 19-year-old woman who developed a unilateral linear eruption 17 months after allogenic peripheral blood stem cell transplantation. Histopathology revealed features, which were consistent with LS. To the best of our knowledge, our patient is the first case describing the appearance of LS occurring after allogenic stem cell transplantation. We speculate that this condition represents an unusual form of localized, chronic graft-versus-host disease.

[Occupational dermatitis in health care personnel].

Barbaud, Annick

2002-09-01

Occupational dermatosis are frequent among healthcare workers. Irritant hand dermatitis is more common than allergic contact dermatitis. It is enhanced by the exposure to irritants: water, detergents, disinfectants and a history of atopic dermatitis. Natural rubber latex contained in rubber gloves can induce contact urticaria or generalized immediate allergic reactions. Contact eczema can be induced by rubber accelerators such as thiurams, disinfectants (glutaraldehyde, dodecyldimethylammonium). Nurses can become sensitized to handled drugs (antibiotics, propacetamol...). These occupational allergies have to be diagnosed, because sensitized nurses can develop severe generalized cutaneous adverse drug reactions if they are systemically exposed to the same drug than those that has previously induced an occupational contact allergy.

Lichen planus is an uncommon disease in children, and only 2 to 3% of affected patients are under twenty years of age. This dermatosis may appear in several clinical forms, which vary according to the morphology and distribution of lesions. In less than 0.2% of all lichen planus cases, the lesions are distributed along the lines of Blaschko, and is a variant called linear lichen planus. This is a case report of a patient aged two years and eight months, who presented keratotic violaceous papules, affecting the abdomen, buttocks and right thigh, distributed along the lines of Blaschko. Histopathological examination confirmed a diagnosis of linear lichen planus. PMID:24346902

Misleading pustular plaques of the lower limbs during Crohn's disease: two case reports

Full Text Available Abstract Background Extraintestinal manifestations of Crohn's disease may involve the skin, the eyes, the genital mucosa, and the joints. Dermatoses associated with Crohn's disease include neutrophilic dermatoses, erythema nodosum, granulomatous dermatitis, blistering dermatoses, and non-specific skin manifestations. Cutaneous Crohn's disease is characterized by skin non-caseating epithelioid granulomatas with giant cells, remote from the gastrointestinal tract. We report herein two new cases. Observations On both patients, differential diagnosis of neutrophilic dermatoses and infectious disease were evoked, and antimicrobial agents were introduced in one of them. Given the atypical presentation, the final diagnosis of cutaneous Crohn's disease could only be made with histological examination. In patient 1, the plaques decreased in size and infiltration by more than 75% after 3 weeks of treatment with bethametasone dipropionate 0.05% cream. In patient 2, the plaques decreased by more than 50% after 6 weeks of treatment with prednisolone (45 mg/day and azathioprine (100 mg/day. Discussion Cutaneous Crohn's disease may present as dusky, erythematous, infiltrated, and ulcerated plaques and nodules. Female-to-male sex ratio is about 2, and the mean age at onset is 35. Recurrently, the hypothesis of a skin mycobacterial or fungal infection greatly delays proper treatment. Rarity of cutaneous Crohn's disease hampers therapeutic assessment in controlled trials. Thus, available literature is limited to case reports and sparse small series, with contradictory results. These reports are subject to publication bias, and no definite evidence-based recommendations can be made on the most adequate therapeutic strategy.

Skalli, Saadia; Barret, Pierre; Villier, Céline; Bussières, Jean-François

2011-01-01

A 15-year-old adolescent was admitted to the hospital for management of a generalized pruritic skin rash, which had appeared 10 days prior to admission. Carbamazepine (CBZ) and insulin were initiated 44 and 23 days prior to the onset of the skin rash (day 44), respectively. Clinical examination showed bluish lesions on the tongue and bilateral keratoconjunctivitis. His skin was very erythematous and pruritic without edema and covered with hundreds of nonfollicular pustules mainly on the trunk and skin folds. Laboratory assessment revealed leukocytosis, hypereosinophilia, and thrombocytopenia. A sample of superficial pus from a pustule on the trunk showed a significant number of leukocytes as well as a significant number of Staphylococcus aureus and Lancefield Group B β-hemolytic streptococci strains. An abdominal skin biopsy revealed acute to subacute folliculocentric spongiotic dermatitis with subcorneal pustules. All of these observations were consistent with a diagnosis of acute generalized exanthematous pustulosis (AGEP). Although we could not exclude with certainty the role of insulin initiated on day 21 and discontinued on day 55 with substitution to oral metformin and repaglinide, no cases of AGEP have ever been published with insulin, and skin lesions were not related to injection sites. This article describes a probable case of CBZ-induced acute generalized exanthematous pustulosis in a 15-year-old adolescent. PMID:22477826

Full Text Available A clinicopalhological study of 70 cases of pemphigus observed over a span of four and a half years from January 1992 to June 1996 at the Sir J.J. Group of Hospitals and Grant Medical College, Mumbai is reported. Pemphigus vulgaris constituted the single largest group of 43 cases, followed by pemphigus foliaceus (25 cases and pemphigus vegetans (2 cases. Majority of the cases were seen in the age group of 21-60 years, with a slight male predominance. The youngest patient was 14 years while the eldest was aged 75 years. Mucosal involvement was seen in 31 cases of pemphigus vulgaris, as opposed to only 5 cases of pemphigus foliaceus. Flaccid bullae were present in 100% cases. Pruritus was complained of in 14 cases, though it was more common in pemphigus vegetans and vulgaris. Salient histopathological features of pemphigus vulgaris observed were (I intraepidermal suprabasal blisters (35 cases, (2 presence of acantholytic cells (40 cases, (3 "Row of tombstone appearance" (I8 cases and (4 acantholysis involving follicular sheath (20 cases. Main histopathological features of pemphigus foliaceus were (1 subcorneal blister (15 case, (2 acantholysis (24 cases and (3 bulla cavity containing inflammatory infiltrate (12 cases. Both cases of pemphigus vegetans showed hyperkeratosis, papillomatosis and irregular acanthosis with intra-epidermal eosinophilic abscesses besides suprabasal lacunae.

Full Text Available Cell-cell adhesion mediated by desmosomes is crucial for maintaining proper epidermal structure and function, as evidenced by several severe and potentially fatal skin disorders involving impairment of desmosomal proteins. Pemphigus foliaceus (PF and staphylococcal scalded skin syndrome (SSSS are subcorneal blistering diseases resulting from loss of function of the desmosomal cadherin, desmoglein 1 (Dsg1. To further study the pathomechanism of these diseases and to assess the adhesive properties of Dsg2, we employed a recently established transgenic (Tg mouse model expressing Dsg2 in the superficial epidermis. Neonatal Tg and wild type (WT mice were injected with purified ETA or PF Ig. We showed that ectopic expression of Dsg2 reduced the extent of blister formation in response to both ETA and PF Ig. In response to PF Ig, we observed either a dramatic loss or a reorganization of Dsg1-α, Dsg1-β, and, to a lesser extent, Dsg1-γ, in WT mice. The Inv-Dsg2 Tg mice showed enhanced retention of Dsg1 at the cell-cell border. Collectively, our data support the role for Dsg2 in cell adhesion and suggest that ectopic superficial expression of Dsg2 can increase membrane preservation of Dsg1 and limit epidermal blister formation mediated by PF antibodies and exfoliative toxins.

Evaluating the febrile patient with a rash.

McKinnon, H D; Howard, T

2000-08-15

The differential diagnosis for febrile patients with a rash is extensive. Diseases that present with fever and rash are usually classified according to the morphology of the primary lesion. Rashes can be categorized as maculopapular (centrally and peripherally distributed), petechial, diffusely erythematous with desquamation, vesiculobullous-pustular and nodular. Potential causes include viruses, bacteria, spirochetes, rickettsiae, medications and rheumatologic diseases. A thorough history and a careful physical examination are essential to making a correct diagnosis. Although laboratory studies can be useful in confirming the diagnosis, test results often are not available immediately. Because the severity of these illnesses can vary from minor (roseola) to life-threatening (meningococcemia), the family physician must make prompt management decisions regarding empiric therapy. Hospitalization, isolation and antimicrobial therapy often must be considered when a patient presents with fever and a rash.

Dandruff is a common scalp disorder affecting almost half of the post-pubertal population of any ethnicity and both genders. It is one of the major reasons for patients to consult a dermatologist and it is the cause of significant psychological and social distress. The aim of this open study was to evaluate the benefit of a 4-week treatment with a shampoo containing 0.1% lipohydroxyacid (LHA) and 1.3% salicylic acid on the scalp condition and on the quality of life of 275 volunteers with seborrheic dermatitis (SD) (n = 226) or light-to-moderate scalp psoriasis (SP) (n = 49). The clinical benefit of the treatment was assessed by scoring the following parameters, i.e., severity of the dermatosis, scaling, itching, excoriations, and superficial burning sensation. The impact on the quality of life was assessed using the Scalpdex, a questionnaire specially developed by Chen et al. for patients with scalp dermatitis, which includes 23 questions regarding the symptoms, functioning and emotions affected by scalp dermatosis. The shampoo used in this study was well tolerated. After a 4-week treatment, dermatologists noticed a significant clinical improvement of all the scalp parameters evaluated (i.e., the composite lesional score was improved in 91% and 77% of the patients with SD or SP respectively). The symptoms, functioning and emotions scores of quality of life were also significantly improved in relation to the improvement of scalp condition. This study not only allowed a better understanding of the SD and SP patient's profile but also demonstrated that the shampoo evaluated is a convenient, efficient, safe, and well-tolerated cosmetic treatment of SD and light-to-moderate SP improving greatly the quality of life of the treated patients.

Uncommon vancomycin: induced side effects

Rocha Jaime Luís Lopes

2002-01-01

Full Text Available Vancomycin has been used with increased frequency during the past 15 years and the most common toxicity with this drug is the "red man syndrome". Other adverse effects include neutropenia, fever, phlebitis, nephrotoxicity, ototoxicity, thrombocytopenia, interstitial nephritis, lacrimation, linear IgA bullous dermatosis, necrotizing cutaneous vasculitis and toxic epidermal necrolysis. Only two cases of vancomycin-induced Stevens-Johnson syndrome and one case of pancytopenia have been reported in the medical literature. The treatment for both situations is based on cessation of the vancomycin therapy; in cases of Stevens-Johnson syndrome, antihistamine and/or steroid agents can be used. This article reports a case of pancytopenia and a case of erythema major associated with neutropenia.

Full Text Available Molluscum contagiosum is a virus-induced dermatologic condition causing characteristic pearly lesions on the surface of skin. The lesion is common in children. In adults, it is usually a sexually transmitted disease. Molluscum contagiosum may be found anywhere on the body, although it rarely occurs on the palms and soles. Dermatosis of nipple due to molluscum contagiosum is rare. If it occurs, it is accompanied by lesions in other sites. Isolated involvement of nipple by the virus is unusual and has been reported only once in previous literature to the best of our knowledge. Here, we report this unusual case of isolated molluscum contagiosum of nipple in 30-year-old female.

Full Text Available Grover's disease is a transient acantholytic dermatosis of unknown cause, manifesting clinically as a papular skin eruption that is usually located on the anterior chest and abdomen. Histologically characterized by an acantholytic pattern, it has been associated with numerous disorders, including hematologic malignancies, chronic renal failure, and HIV infection, as well as with chemotherapy and bone marrow and/or kidney transplant. Evaluation of followup and treatment is often complicated by spontaneous remission and the occasionally fluctuant course of the disease. Here we report the case of a patient with sudden onset of Grover's disease after heart transplantation. To the best of our knowledge, this is the first observation of Grover's disease as diagnosed after heart transplantation.

Annular lichenoid dermatitis of youth is a lichenoid dermatosis of unknown etiology. It mostly affects children and adolescents and has well-defined clinical and histological characteristics that permit a diagnosis. We present 2 new cases of annular lichenoid dermatitis of youth with classical clinical features in 2 girls, aged 2 and 4 years. The histologic findings, however, differed from those reported in the literature in that the lichenoid inflammatory infiltrate was located primarily at the top of the dermal papillae and not at the tips of the rete ridges. In both cases, the lesions regressed spontaneously without treatment. Copyright © 2016 AEDV. Published by Elsevier España, S.L.U. All rights reserved.

Full Text Available Lichen sclerosus (LS, also known as lichen sclerosus et atrophicus is a chronic inflammatory dermatosis of unknown aetiology. It has both genital and extragenital presentations, nevertheless genital forms significantly outnumber extragenital LS. Dermoscopy is noninvasive diagnostic tool traditionally employed in pigmented lesions, however its usefulness in inflammatory skin conditions is becoming continuously more meaningful. Although the clinical diagnosis of fully developed LS rarely causes difficulties, unusual presentations require differentiation from the diseases such as lichen planus, morphea, extramammary Paget disease, SCC and others. In these cases histopathology contributes to the diagnosis. Studies on the use of dermoscopy in LS are sparse, nevertheless some dermoscopic features of LS has been described.

Skin manifestations associated with chronic kidney disease are very common. Most of these conditions present in the end stages and may affect the patient's quality of life. Knowledge of these entities can contribute to establishing an accurate diagnosis and prognosis. Severe renal pruritus is associated with increased mortality and a poor prognosis. Nail exploration can provide clues about albumin and urea levels. Nephrogenic systemic fibrosis is a preventable disease associated with gadolinium contrast. Comorbidities, such as diabetes mellitus and secondary hyperparathyroidism, can lead to acquired perforating dermatosis and calciphylaxis, respectively. Effective and innovative treatments are available for all of these conditions. Copyright © 2015 Elsevier España, S.L.U. and AEDV. All rights reserved.

Full Text Available Cutaneous collagenous vasculopathy (CCV is a distinct, rare, and underdiagnosed condition. We report a case of CCV in a 50-year-old woman presenting as asymptomatic, erythematous to hyperpigmented nonblanchable macules over both the lower extremities. The clinical differential diagnosis of the lesions was pigmented purpuric dermatoses (Schamberg's purpura and cutaneous small vessel vasculitis. Histology of the lesions revealed dilated superficial dermal vessels with abundant pink hyaline material in the vessel wall, which stained with periodic acid Schiff stain. The patient was diagnosed as CCV. This condition remains largely underdiagnosed and is commonly mistaken for pigmented purpuric dermatosis or generalized essential telangiectasia. Emphasis on the differentiation of CCV from its clinical and histological mimicks is made.

Palmoplantar lichen planus is an uncommon dermatosis. We present a case of 38-year-old Caucasian male with a history of pruritic, scaly lesions on the right plantar foot. Physical examination revealed whitish plaques and numerous spiny hyperkeratotic papules and focal scaling. A biopsy demonstrated orthohyperkeratosis and acanthosis of the epidermis. Immunohistochemical staining revealed positivity within the epidermis and/or lichenoid infiltrate with CD3, CD8, CD45, CD68, myeloid histiod antigen, BCL2, p27, p53, HLA-DPDQDR, metallothionein and tissue inhibitor of metalloproteinases 1. The diagnosis of PPLP was thus confirmed; this case illustrates that PPLP should be considered in the differential diagnosis of uncommon foot dermatoses with a significant junctional inflammatory component.

Cutaneous larva migrans – a threat to divers in the tropics

Directory of Open Access Journals (Sweden)

Olszański Romuald

2016-09-01

Full Text Available The article presents a dermatosis that occurs in tropical and subtropical countries. Though the definitive hosts of the cutaneous larva migrans parasite are animals, humans can become accidental hosts and they are infected when their skin comes into contact with damp soil, most frequently sand. The disease is only present in the epidermis where an itch is brought about by the mining activity of the larva. Sunbathers and divers who put on their gear on a beach, on account of the epidermis maceration caused by a prolonged exposure to water, are particularly susceptible to the penetrative activities of the larva. In Poland the cutaneous larva migrans is in most cases mistaken for nettle rash or eczema.

Pyoderma Vegetans: A Case Report in a Child Suspected to Primary Immunodeficiency and Review of the Literature

Full Text Available Pyoderma vegetans (PV is a rare inflammatory disorder characterized by vegetating pustules and plaques affecting the skin and mucosal membranes. It is believed that this entity is mostly associated with inflammatory bowel disease (IBD, chronic malnutrition, human immunodeficiency virus (HIV, malignancies, and other immunocompromised states. Pyoderma vegetans occurs more commonly in young and middle-aged adults. There is no sex predilection for this entity. The lesions could heal spontaneously, but usually recur and become chronic. Our patient was an 11-year-old girl suspected to have primary combined immunodeficiency complicated by chronic recurrent vegetating pustular lesions on the face and postauricular area since one year of age. The histological features of the lesions were consistent with pyoderma vegetans. This is the first case of PV beginning from early infancy in the setting of primary immunodeficiency and in an unusual location.

The skin in psoriasis: assessment and challenges.

Science.gov (United States)

Oji, Vinzenz; Luger, Thomas A

2015-01-01

The coexistence of psoriasis arthritis (PsA) and psoriasis vulgaris in about 20% of patients with psoriasis leads to a need for rheumatologic-dermatologic team work. We summarise the role of dermatologists in assessment of the skin in psoriasis. Chronic plaque psoriasis must be differentiated from other subtypes such as generalised pustular psoriasis (GPP) or palmoplantar pustulosis (PPP). Therapeutic management is based on the evaluation of the disease severity. Quantitative scoring of skin severity includes calculation of the Psoriasis Area and Severity Index (PASI), body surface area (BSA) as well as the Dermatology Life Quality Index (DLQI). These scoring systems do not replace the traditional dermatologic medical history and physical examination of the patient. The skin should be examined for additional skin diseases; moreover, patients should be monitored for comorbidity, most importantly PsA and cardiovascular comorbidity.

1979-07-01

The case of a 50 year old male with the Fiessinger-Leroy-Reiter syndrome, ankylosing spondylitis and generalised pustular psoriasis is reported. This condition wax complicated by non-obstructive cardiomyopathy, congestive cardiac failure and first-degree atrioventricular block, the site of which was localised by electrophysiological studies (nodal block with an infrahisian conduction defect). After failure of several therapeutic regimes, a spectacular improvement was obtained with Methotrexate associated with a diuretic; the signs of heart failure regressed and the cardiomyopathy stablised. A parallel improvement was seen in the skin, cardiac and articular lesions and has been maintained with an 18 months follow-up. Left ventricular performance was studied by echocardiography. The mechanism of the beneficial effect of Methotrexate is unclear; this therapeutic trial is to be extended to include other cases of primary cardiomyopathy without obstruction.

2017-10-01

Full Text Available Granuloma faciale is an uncommon benign chronic dermatosis characterized by reddish-brown to violaceous asymptomatic plaques appearing predominantly on the face. The pathogenesis of granuloma faciale remains unclear, and it is frequently unresponsive to therapy. This systematic review aims to summarize all recent publications on the management of granuloma faciale. The publications are mainly individual case reports, small case series and a few retrospective studies. Treatment options included topical, intralesional and systemic corticosteroids, topical pimecrolimus and tacrolimus, topical and systemic dapsone, systemic hydroxychloroquine, clofazimine, and tumour necrosis factor-alpha inhibitors. More invasive therapies using lasers as well as cryosurgery and surgery were also reported. Topical glucocorticosteroids and tacrolimus remain treatments of first choice, possibly supplemented by topical dapsone.

There are a variety of dermatological diseases that are more commonly seen in patients with chronic kidney disease (CKD) and renal transplants than the general population. Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science has been searched. Some cutaneous diseases are clearly unique to this population. Of them, Lindsay's Nails, xerosis cutis, dryness of the skin, nephrogenic systemic fibrosis and acquired perforating dermatosis have been described in chronic kidney disease patients. The most common malignancy found in all transplant recipients is non-melanoma skin cancer. It is important for patients and physicians to recognize the manifestations of skin disease in patients suffering from chronic kidney disease to mitigate the morbidity associated with these conditions.

Circumscribed palmar or plantar hypokeratosis is a rare dermatosis characterized by a solitary, well-circumscribed patch with scaly borders chiefly on the palm or sole; it usually occurs in middle-aged or elderly women. We report the case of a 52-year-old Korean woman with two characteristic lesions of circumscribed palmar hypokeratosis on the left palm. Clinically, the lesions simulated porokeratosis of Mibelli, but histologically there was no cornoid lamellation in the serial sections and there were the characteristic histopathological features of circumscribed palmar or plantar hypokeratosis including a stair-like configuration with an abrupt thinning of the stratum corneum and a decreased granular layer. We also review the 16 cases of circumscribed palmar or plantar hypokeratosis reported in the published work.

IDIOPATHIC ERYTHEMA NODOSUM AND PREGNANCY: DESCRIPTION OF A CASE

Directory of Open Access Journals (Sweden)

B S Belov

2009-01-01

Full Text Available Erythema nodosum (EN is a dermatosis of unclear etiology, which is characterized by vascular lesion of the skin; it shows itself as hard painful nodes occurring in the derma or subcutaneous fat on the shins and thighs. EN has been described in many chronic infectious processes with some features of its clinical course. In most cases, the disease is regarded as a nonspecific immunoinflammatory response to a wide spectrum of etiological factors, including that in gestation, which presents certain problems in curing the patient. The example given below supports the need for timely testing for infectious markers in pregnancy and, in case of evolving EN, for using not only nonsteroidal anti-inflammatory drugs, but also pathogenetic treatment.

Depending on the intervention, the animals were divided into 5 equal groups with 10 animals in each group: Group 1 included rats with intact eyes (the control group and Groups 2 through 5 were experimental groups with EAB. Group 2 consisted of rats subjected to instillation of 0.25% chloramphenicol solution; Group 3 consisted of rats subjected to photodynamic irradiation according to our scheme: 300 mJ (630 nm for 3 minutes; Group 4 consisted of rats subjected to instillation of methylene blue (MB; Group 5 consisted of rats subjected to instillation of MB with subsequent photodynamic irradiation according to the described scheme. During all periods of observation, the infiltration of the subcorneal zone was less pronounced in Group 5 than in the other groups and was represented mainly by round cells in the anterior chamber, iris, retina, and ciliary zone. The instillation of MB with subsequent photodynamic irradiation was the most effective in reducing the bacterial contamination Thus, PDT with the photosensitizer methylene blue, in accordance with the designed exposure mode, provided the epithelialization and bacteriostatic effect during corneal repair after EAB. In conclusion, PDT improves a wound’s healing process, which is expressed in the reduction of inflammatory infiltration and the promotion of corneal epithelialization.

Diltiazem-induced acute generalised exanthematous pustulosis.

Pustulation is a major feature in several different dermatoses, and it may also occur as a manifestation of drug hypersensitivity. Acute generalized exanthematous pustulosis (AGEP) is an uncommon eruption characterized by acute, extensive formation of sterile pustules, fever and peripheral blood leucocytosis. It shares several clinical and histological features in common with pustular psoriasis. Most reported cases have been triggered by ingestion of broad spectrum antibiotics, particularly betalactams and macrolides. There is usually rapid resolution of the eruption on drug withdrawal. We report the case of a 58 year-old woman who developed AGEP shortly after commencing treatment with the calcium channel blocker diltiazem hydrochloride. The eruption followed a biphasic course, and improved following treatment with systemic corticosteroids and methotrexate. AGEP appears to be a rare adverse cutaneous reaction to diltiazem, whereas a wide range of other skin eruptions have been reported more commonly with this drug.

Full Text Available Abstract Background Demodex gatoi is unique among demodectic mites. It possesses a distinct stubby appearance, and, instead of residing in the hair follicles, it dwells in the keratin layer of the epidermis, causing a pruritic and contagious skin disease in cats. Little is known of the occurrence of D. gatoi in Europe or control of D. gatoi infestation. Case presentation We describe D. gatoi in 10 cats, including five Cornish Rex, two Burmese, one Exotic, one Persian and one Siamese, living in six multi-cat households in different locations in Finland containing 21 cats in total. Intense pruritus was the main clinical sign. Scaling, broken hairs, alopecia and self-inflicted excoriations were also observed. Diagnosis was based on finding typical short-bodied demodectic mites in skin scrapings, skin biopsies or on tape strips. Other pruritic skin diseases, such as allergies and dermatophytoses, were ruled out. In one household, despite finding several mites on one cat, all six cats of the household remained symptomless. Amitraz used weekly at a concentration of 125-250 ppm for 2-3 months, proved successful in three households, 2% lime sulphur weekly dips applied for six weeks in one household and peroral ivermectin (1 mg every other day for 10 weeks in one household. Previous trials in four households with imidacloprid-moxidectin, selamectin or injected ivermectin given once or twice a month appeared ineffective. Conclusion D. gatoi-associated dermatitis is an emerging contagious skin disease in cats in Finland. Although pruritus is common, some cats may harbour the mites without clinical signs. In addition, due to translucency of the mites and fastidious feline grooming habits, the diagnosis may be challenging. An effective and convenient way to treat D. gatoi infestations has yet to emerge.

Many nutritional factors can affect the quality and the aspect of the coat. B complex vitamins are water-soluble compounds used as coenzymes in several cellular functions that are involved in energy metabolism and tissue synthesis. Biotin, in particular, is necessary for carboxylation reactions, fatty acids synthesis, and incorporation of essential amino acids and purines in the epithelial tissue. A female canine with recurrent cystitis and sticker tumor was treated chemotherapy and prolonged antibiotic therapy. After a few months of medications, lesions were observed in nasal plan and palmar and plantar pads, characterized by hyperkeratosis, skin thickness, bleeding fissures, and inflammation. The patient was treated with 15mg of oral biotin supplementation (1.4mg kg-1 of body weight once a day, for 60 days, with significant regression of skin lesions at the end of this period. These findings suggest that in certain diseases and particularly in prolonged antibiotics therapy, intestinal biotin synthesis may not be adequate, demanding oral supplementation.

Full Text Available External therapy with topical steroids is used for a long time. To date topical glucocorticosteroids (TGCS are in the leading position in dermatology among all medicines for external therapy. TGCS as a powerful tool of pathogenic action can rapidly reduce or decrease inflammatory changes in the skin and eliminate subjective symptoms of dermatoses (itching, burning. their positive effect lead to the rehabilitation of working ability and daily living activity, positively affect the psychoemotional state and significantly improve the patient’s quality of life. Urea in dermatology has been used for a very long time, as it softens the skin, reduces its dryness and eliminates peeling. In recent decades interest in this compound has intensified after a formation of an idea about natural moisturizing factor (NMF - a complex of substances (which includes urea being a part of the intercellular matrix of the epidermis and capable of retaining the water in the epithelial layer of the skin necessary for its normal functioning. The article presents modern literature data on the reasoning of the inclusion of a combination of topical glucocorticosteroids with urea in a complex therapy of steroid-responsive dermatoses.

La criptococosis cutánea es una micosis propia de pacientes inmunodeprimidos, sobre todo aquellos con infección por el virusde la inmunodeficiencia humana (VIH). Sin embargo, existen casos infrecuentes de criptococosis cutánea en pacientes inmunocompetentes, que suelen simular otras dermatosis, lo que retrasa su diagnóstico y tratamiento. Presentamos el caso de un varón pluripatológico de 79 años, con úlceras dolorosas en dorso de mano derecha que no respondían a tratamientos tópicos. A través del estudio histopatológico y micológico se alcanzó el diagnóstico de criptococosis cutánea primaria, lográndose la remisión de las lesiones tras 6 meses de tratamiento con fluconazol.

Delayed diagnosis of post-surgical pyoderma gangrenosum: A multicenter case series and review of literature

Directory of Open Access Journals (Sweden)

Rawaa Almukhtar

Full Text Available Introduction: Pyoderma gangrenosum is a chronic neutrophilic dermatosis which can occur following trauma or surgery and can mimic infection. Surgical intervention can lead to progression of disease. Presentation of cases: This case series describes 3 cases of post-surgical pyoderma gangrenosum with delayed diagnosis from two large medical centers. Discussion: Epidemiology, pathogenesis, clinical and histopathologic presentation, and management of post-surgical pyoderma gangrenosum are discussed with a review of the literature. Conclusion: Post-surgical pyoderma gangrenosum (PSPG can mimic ulcerative disorders including bacterial infection. The diagnosis should be suspected in post-operative wounds with negative bacterial cultures which progress despite broad-spectrum antibiotics and surgical debridement. Recognizing the clinical features of PSPG is fundamental to prevent severe destruction and deformity. Keywords: Post-surgical, Pyoderma gangrenosum, Necrotizing fasciitis, Case report

Herpes zoster on segmental vitiligo: Wolf’s isotopic response?

Mankesh Lal Gambhir

2014-04-01

Full Text Available “Wolf’s isotopic response” describes the occurrence of a new skin disorder at the site of another, unrelated and already healed skin disease. In most cases of isotopic response, the initial dermatosis is herpes zoster, herpes simplex, varicella, thrombophlebitis, scrofuloderma and striae distense. The most frequent second dermatoses are granulomatous reactions, particularly granuloma annulare, and lichenoid diseases. Various etiological reasons including viral, immunologic, neural and vascular have been put forth. We report here a case in which the second disease was herpes zoster that appeared over the same dermatomes of pre-existing segmental vitiligo. The occurrence of vitiligo as first and herpes zoster as second disease in the “Wolf’s isotopic response” has not, to the best of our knowledge, been reported previously.

Full Text Available Erythema ab igne (EAI is a reticulated, telangiectatic, and hyperpigmented skin eruption resulting from chronic exposure to long-term moderate heat. The incidence has decreased substantially today because of the advent of modern central heating systems. Recently, we encountered a patient who developed EAI after 2 weeks of footbaths with Chinese herbal remedies, which she used to treat her acute ankle sprain. Alternative Chinese medicine, such as herbal footbath, is a prevalent medical practice to treat acute pains as well as many chronic musculoskeletal ailments among Chinese and Asian populations. It has also become increasingly popular in Western countries in the past decade. Herein, we would like to report an uncommon case of iatrogenic EAI caused by footbath and raise the attention of clinicians to such rare, potentially malignant-transforming, dermatosis.

Vulvar Skin Disorders throughout Lifetime: About Some Representative Dermatoses

Jean Doyen

2014-01-01

Full Text Available The objective of this paper is to present general considerations which should be kept in mind by clinicians in charge of women with vulvar diseases. Four representative vulvar dermatoses are described. Lichen simplex chronicus is a pathological condition related to chemical and mechanical irritant agents. Detrimental effects of these irritants, in the presence of other dermatoses, have to be considered when therapeutic responses are unsatisfactory. Lichen sclerosus is the most common vulvar dermatosis in elderly. However, it should be kept in mind that it may be diagnosed at any age. Lichen planus, in spite of sharing a similar range of etiological factors with lichen sclerosus, is a very distinct entity. Finally, Paget’s disease, although rare, is also described especially because of the challenge it represents both clinically and therapeutically.

2017-06-01

Schnitzler syndrome (SS) is an autoinflammatory dermatosis that often goes undiagnosed for 5-6 years. Patients typically carry a diagnosis of urticaria; however, their cutaneous symptoms fail to respond to typical urticaria therapies and lack symptoms such as pruritus. Additionally, patients with SS may see multiple providers for nonspecific complaints of fever, lymphadenopathy, arthralgias, and bone pain. A correct diagnosis is paramount, as close to 20% of patients may develop a lymphoproliferative disorder and appropriate treatment may ameliorate all symptoms.1 We report 2 cases of SS misdiagnosed as urticaria for years in order to illuminate diagnostic pearls, histopathological findings, and treatment modalities. Additionally, we highlight the importance of neurologic disturbances in this rare but important differential diagnosis of urticaria. J Drugs Dermatol. 2017;16(6):625-627..

Selective UV-Phototherapy with lambda 300-320 nm (SUP) as well as oral photochemotherapy with 8-methoxy-psoralen plus UVA-radiation (PUVA intern) are very effective in clearing the lesions of the generalized psoriasis and those of the chronic forms of parapsoriasis. Being treated with 4 suberythemal doses per week psoriasis patients are free or nearly free of symptoms after averagely 6.3 weeks of SUP-therapy or after 5.3 weeks of PUVA orally. The PUVA-therapy is mainly indicated in pustular, inverse and erythrodermic psoriasis as well as in parapsoriasis en plaques and variegata. In all other forms of psoriasis and in pityriasis lichenoides-chronica, we prefer the SUP-therapy because of less acute or chronic side effects, and because of its better practicability. X-rays are indicated in psoriais of nails, grenz-rays in superficial psoriatic lesions of the face, the armpits, the genitals and the anal region. (orig.) [de

Rhinophyma in tuberous sclerosis complex: case report with brief review of literature

Friedrich, Reinhard E.

2014-11-01

Full Text Available Tuberous sclerosis or tuberous sclerosis complex (TSC is an autosomal dominant inherited disease characterized by the triad epilepsy, hamartomas (angiofibroma and reduced intellectual capacity. Phenotype can vary considerably. Almost all patients with TSC have at least one characteristic dermatologic feature. Facial angiofibroma can cause severe disfigurement. It may involve the cheeks, perioral region and nose, resulting in thick layers of nodular and pustular skin. Aesthetic surgery of the face comprises an individually adapted ablation of the affected skin regions in order to improve physical appearance. Reports on the subject of surgery for nasal angiofibroma confirm the homogenous transformation of the connective tissues by this hamartoma. Hitherto there is only one report in the literature describing the typical epithelial alterations of the nasal skin compatible with a rhinophyma and adjacent angiofibroma. Here we report the successful electrosurgical treatment of a patient with TSC and extensive sebaceous glands giving rise to a rhinophyma in close association with angiofibroma.

Full Text Available Despite recent advances in understanding the pathological pathways, clinical pattern and management opportunities for new-onset psoriasis as a paradoxical adverse event in patients receiving TNF inhibitors for their immune-mediated disorder, there is a subset of patients who are either partial responders or non-responders, whatever the therapeutic scenario. We present the case of new-onset psoriasis and severe alopecia development in a case study of long-standing rheumatoid arthritis (RA treated with adalimumab (ADA and leflunomide. Since skin lesions and alopecia are resistant to the classic protocol (topical treatment, ADA discontinuation and RA becomes highly active, rituximab (RTX was started. Dramatic improvement in joint disease, total remission of alopecia and partial remission of pustular psoriasis were described after the first RTX cycle. Although B-cell-depleting agents result in controversial effects on psoriatic skin lesions, this is the first case of ADA-induced psoriasis and alopecia that improved under RTX, suggesting a possible role in treating such a patient population.

1985-01-01

Thirty-seven dogs with pemphigus foliaceus were seen over a span of 9 years in a veterinary medical teaching hospital. Four breeds of dogs (Bearded Collie, Akita, Newfoundland, Schipperke) were at significant elevated risk when compared with both the dermatology canine case population and the hospital canine population. The mean age of onset was 4.2 years. The dorsal part of the muzzle was the most common site of initial involvement in over 50% of the dogs, and lesions of the head were seen first in 81% of the dogs. Disease progression was gradual (greater than 3 months) in 73% of the dogs. Somewhat bilaterally symmetric scaling, crusting, and alopecia were seen in all of the dogs. Vesicles, pustules, and bullae were not seen commonly, but target lesions with peripheral collarettes were seen frequently. Most dogs had characteristic footpad lesions, with erythematous swelling at the pad margins, cracking, and villous hypertrophy. Generalized exfoliative dermatitis was seen in dogs with widespread disease. Pruritus was noted in less than one half of the dogs. Typical histopathologic findings included subcorneal and intragranular cell layer epidermal pustules, or intrafollicular pustules with prominent acantholysis. Direct immunofluorescence in an intercellular pattern was noted in 76% of the dogs tested and indirect immunofluorescence was noted in 75% of a much smaller sample. Thirty-nine percent of the dogs responded to corticosteroid therapy alone, and 50% and 55% responded, respectively, to prednisone and cytotoxic drugs, and to prednisone with aurothioglucose. Aurothioglucose was successful alone in 27% of the dogs. One-year survival was achieved in 53% of the dogs.

2006-01-01

Peeling skin syndrome (PSS) is a rare genodermatoses of probable autosomal recessive inheritance in Saudi Arabia, consanguinity of parents is common and consequently the occurrence of family disease, including that of the skin, is not uncommon. To characterize the clinical and pathological features of PSS in Saudi Arabia, we reviewed the medical records and clinical photographs of patients with recurring blistering diseases and conducted a histopathologic evaluation of skin biopsies to identify the site of cleavage. Eleven persons with PSS were seen at King Khalid National Guard Hospital in Jeddah between the years 1986 and 2005. Ages ranged between 2 and 15 years and there were 9 males (81.8%) and 2 females (18.2%). The most common presentation in the majority of patients was localized spontaneous peeling of the skin. Eight patients (72.8%) had a history of vesicles that were small, dry and peeled away. Trauma did no play role in blister formation. All patients were local from Bedouin tribes where a family history of a similar complaint was documented in 8 cases (72.7%). And consanguinity of marriage was evident on 6 patients (54.5%). Histological examination of the biopsies showed either intracorneal or superficial subcorneal cleavage above the granuler layer in all biopsied patients. Although rare, PSS occurs in Saudi Arabia and is most likely related to consanguinity of marriages. This disease is generally mild and is characterized by intrascorneal cleavage within the superficial epidermis. The disease should be recognized and not confused with other vasicobullous disease.

Polycystic ovarian syndrome is a common endocrine disorder with a variety of dermatologic manifestations among young women. Confluent and reticulated papillomatosis is a rare dermatosis of unknown etiology that is seldom reported in patients with polycystic ovarian syndrome. We describe the case of a young woman with obesity, confluent and reticulated papillomatosis, and concurrent acanthosis nigricans. Her history, physical examination, and laboratory evaluation led to the diagnosis of polycystic ovarian syndrome. The proposed etiologies and the various of treatment options for confluent and reticulated papillomatosis are discussed. In our case, the patient had a dramatic response to treatment with azithromycin. The etiology of confluent and reticulated papillomatosis remains to be established. Additionally, the mechanism behind the success of treatment with antibiotics is unclear; however, in this patient, azithromycin was a safe and effective option for the treatment of confluent and reticulated papillomatosis.

Telem, Dana Fuchs; Israeli, Shirli; Sarig, Ofer; Sprecher, Eli

2012-04-01

Generalized peeling skin syndrome (PSS) is a rare autosomal recessive dermatosis manifesting with continuous exfoliation of the stratum corneum. The inflammatory (type B) subtype of PSS was recently found to be caused by deleterious mutations in the CDSN gene encoding corneodesmosin, a major component of desmosomal junctions in the uppermost layers of the epidermis. In the present study, we assessed a 10-month-old baby, who presented with generalized superficial peeling of the skin. Using PCR amplification and direct sequencing, we identified the third PSS-associated mutation in CDSN, a homozygous 4 bp duplication in the second exon of the gene (c.164_167dup GCCT; p.Thr57ProfsX6). These data further support the notion that corneodesmosin deficiency impairs cell-cell adhesion in the upper epidermis, paving the way for an abnormal inflammatory response due to epidermal barrier disruption.

Obtulowicz, A.; Pirowska, M.; Kosiniak-Kamysz, A.

2011-01-01

In the course of radiation therapy different types of adverse reactions of the skin are observed in approximately 95% of patients. Among the various complications encountered after radiotherapy, radiation recall dermatitis (RRD) deserves special attention. Radiation dermatitis is a form of delayed hypersensitivity of irradiated skin, and the direct trigger factors are medicines - most chemotherapeutics. The reaction is an inflammatory dermatosis. It is limited to previously irradiated skin and appears a number of months after radiotherapy. The aetiology of RRD is still unclear. Its clinical presentation may vary from mild erythema to necrosis and ulceration. The article presents the case of a 50-year-old patient, who after radiotherapy for breast cancer, during the hormonal therapy (tamoxifen), developed RRD type skin reactions after skin application of Amol. The article presents a detailed differential diagnosis of skin changes of RRD type, and discusses the principles of treatment and prevention. (authors)

Full Text Available Lichen striatus (LS is an uncommon, acquired, self-limiting, linear inflammatory dermatosis. The eruption typically presents as pink or tan papules along Blaschko’s lines. It usually occurs in children, rarely affects adults. The rashes usually suddenly emerge in a single extremity and may regress within a few months or years. The incidence is slightly higher among women. The etiology of LS is not exactly known, however, it is thought to be a T cell-mediated autoimmune reaction. Trauma, infection, pregnancy, drugs, vaccination, and atopy have been reported as triggering factors. In the literature, four cases of LS developing after vaccination (3 children and 1 adult have been reported. It was the only reported adult case of LS developing after hepatitis B virus vaccination. Herein, we present a 36-year-old woman with LS which was thought to be triggered by a tetanus vaccine.

Full Text Available Introduction . Lichen nitidus (LN is a rare, chronic, inflammatory dermatosis usually affecting children and young adults. Nails involvement is very rare. Until now, 7 cases of LN with nail involvement have been described. Objective. To present a rare case of childhood lichen nitidus where trachyonychia was the main manifestation of the disease. Case report. A 7-year-old, Caucasian, previously healthy boy presented thumbnail longitudinal ridges, distal splitting and subungual hyperkeratosis for 7 months. Numerous mycological and bacteriological examinations were negative. Dermatological examination also revealed erythematous lesions on the proximal nail fold as well as small skin-pigmented papules on the thumb. Similar papules grouped into patches were also observed on the upper limbs, trunk and forehead. Treatment was not recommended. Conclusions . Lichen nitidus may rarely affect nails and should be considered as a possible cause of nail lesions in childhood.

Malnutrition and skin disease in Far East prisoners-of-war in World War II.

Science.gov (United States)

Creamer, D

2018-05-31

During the Second World War, thousands of captured British and Commonwealth troops were interned in prisoner-of-war (POW) camps in the Far East. Imprisonment was extremely harsh, and prisoners developed multiple pathologies induced by physical hardship, tropical infections and starvation. Immediately after the war, several POW doctors published their clinical experiences, including reports of skin disease caused by malnutrition. The most notable deficiency dermatoses seen in Far East POWs were ariboflavinosis (vitamin B2 or riboflavin deficiency) and pellagra (vitamin B3 or niacin deficiency). A lack of vitamin B2 produces a striking inflammatory disorder of scrotal skin. Reports of pellagra in POWs documented a novel widespread eruption, developing into exfoliative dermatitis, in addition to the usual photosensitive dermatosis. A review of the literature from 70 years ago provides a reminder of the skin's response to malnutrition. © 2018 British Association of Dermatologists.

Full Text Available Hak Yung Ng Department of Paediatrics and Adolescent Medicine, Tseung Kwan O Hospital, Tseung Kwan O, Hong Kong, China Abstract: Obesity in adolescence is a public health priority because it usually tracks into adulthood, resulting in enormous medical and social costs. This underscores the importance of early identification and intervention. Acanthosis nigricans (AN was once considered a rare paraneoplastic dermatosis, but is now frequently observed in obese adolescents. Current understanding suggests that it is associated with insulin resistance and has a unique role in secondary prevention. The purpose of this narrative review is to provide a comprehensive overview of AN in obese adolescents, covering its history, current knowledge on the condition, its clinical significance, management challenges, and the direction of future research.

Payette, Michael J; Weston, Gillian; Humphrey, Stephen; Yu, JiaDe; Holland, Kristen E

2015-01-01

Lichenoid dermatoses, a group of inflammatory skin conditions with characteristic clinical and histopathologic findings, range from common to rare. Classic lichen planus typically presents as pruritic, polygonal, violaceous flat-topped papules and plaques; many variants in morphology and location also exist. Other lichenoid dermatoses share similar clinical presentations and histopathologic findings. These include lichenoid drug eruption, lichen planus-like keratosis, lichen striatus, lichen nitidus, and keratosis lichenoides chronica. Epidemiologic characteristics vary among each lichenoid disorder. While classic lichen planus is considered a disease of adults, other lichenoid dermatoses may be more common in younger populations. The literature contains an array of reports on the variations in presentation and successful management of lichen planus and lichenoid dermatoses among diverse populations. Familiarity with the characteristics of each lichenoid dermatosis, rare or common within each patient population, is key to accomplishing timely recognition and effective management.

Full Text Available To use food-specific IgG antibody detection to explore its application in the allergy dermatoses. 181 patients were included from January 2014 to September 2014. Fourteen food-specific IgG antibodies were detected by ELISA. The positive rates of IgG antibody of the patient group and the healthy group were significantly different. The positive rates of IgG antibody of egg, milk, shrimp and crab took a large proportion in three groups of patients with three kinds of allergy dermatoses of urticaria, eczema and allergic dermatitis, the proportion of which was respectively 70.2%, 77.8% and 71.7%. There was mild and moderate intolerance of food in the allergic dermatitis group while there was no distribution difference of food intolerance in urticaria group and eczema group. Among urticaria and allergic dermatitis patients with positive antibody, the positive rate of children was significantly higher than that of adults while there was no significant difference between children and adults among eczema patients with positive antibody. Allergy dermatoses are closely related to food-specific IgG antibody and the allergy dermatoses patients have a high incidence rate of food intolerance; detecting IgG antibody in patients is of great significance for the diagnosis and treatment of allergy dermatoses.

Full Text Available Sporotrichosis is a cutaneous or systemic fungal infection caused by Sporothrix schenckii. The infection is characterized by nodular, pustular, or ulcerative lesions. Infection usually occurs after traumatic implantation of the fungus into the skin. We report a case presenting first cellulitis and later on as a non-healing ulcer which was diagnosed by punch biopsy as sporotrichosis and managed successfully with itraconazole. A 56-year-old woman admitted to our department with complaint acute onset of swelling of the right lower-extremity with erythema and warmth. The patient was diagnosed initially as celulitis and started on ampicillin-sulbactam. Diagnosis of sporotrichosis was made with histological examination skin biopsy and the patient was started on itraconazole. One month after commencement of antifungal treatment, the ulcer began to dry up and at 3 months the lesions had healed. This case shows that if a wound do not respond to antibiotics in cases with ulcer, some rare etiological agents should be considered. [Dis Mol Med 2016; 4(3.000: 34-36

Trichosporonosis is an opportunistic infection caused by the genus Trichosporon. The majority of cases of invasive trichosporonosis occurs in immunocompromised individuals. We describe a case of disseminated infection by Trichosporon asahii in a hematology patient. A 52-year-old man diagnosed with acute lymphoblastic leukemia developed a febrile episode during the third cycle of the induction chemotherapy. The blood cultures were positive after 24h incubation, showing elongated structures compatible with fungal elements in the Gram stain. The identification of the fungus as Trichosporon asahii was carried out by the assimilation of compounds of carbon and the amplification and sequencing of the D1/D2 domain and the internal transcribed spacer of the ribosomal DNA. The fungus was also isolated from the pustular lesions that the patient had in the chest. After treatment with amphotericin B, the patient progressed satisfactorily. Trichosporon asahii is an emergent pathogen in immunosupressed patients and its presence should not be considered as colonization, as there is risk of invasive infection.

1998-01-01

The objective of our study was to clarify the radiologic spectrum of disease entities belonging to the SAPHO syndrome (SAPHO being an acronym for synovitis, acne, pustulosis, hyperostosis, and osteitis). A retrospective analysis of radiologic data was undertaken to determine the relationship of the osteoarthritic changes seen in palmoplantar pustulosis (PPP, n = 179), acne (n = 3), psoriasis vulgaris (PsV, n = 355), generalized pustular psoriasis (GPP, n = 25), and chronic recurrent multifocal osteomyelitis (CRMO, n = 4). Osseous changes of PPP, acne, and CRMO overlap each other; 7 PPP, 2 acne, and 3 CRMO patients manifested stenocostoclavicular hyperostosis as well as hyperostosis of the spine, pelvis, and/or femur. These findings were not seen in either PsV or GPP patients. Thirteen PsV and 4 GPP patients had peripheral arthritis and/or symmetrical sacroiliitis, which were not observed in the PPP, acne, and CRMO patients. The PPP, acne, and CRMO patients may be grouped as belonging to the single disease entity, namely SAPHO syndrome. Our findings do not support the inclusion of PsV and GPP in the spectrum of this syndrome. (orig.)

Palmoplantar psoriasis is associated with significant quality-of-life issues. Its epidemiology and phenotypical expression remain ill defined. We reviewed the literature and our clinical experience and developed a new quality-of-life assessment tool. We conducted a retrospective review of 150 patients with palmoplantar psoriasis. In all, 78 (52%) patients displayed predominantly hyperkeratotic palmoplantar lesions, 24 (16%) pustular, 18 (12%) combination, and 30 (20%) had an indeterminate phenotype. In 27 (18%) patients, lesions were confined to the palms and soles. A new quality-of-life index was constructed to characterize disease severity. In all, 27 (18%) had mild, 72 (48%) moderate, and 51 (34%) severe disease involvement. Palmoplantar disease severity appeared independent from the degree of body surface area involvement. This was a retrospective review. The quality-of-life index remains to be statistically verified in prospective clinical studies. Defining morphologic subtypes together with the use of a specific quality-of-life assessment tool in patients with palmoplantar psoriasis will improve our understanding and treatment of this recalcitrant form of psoriasis.

A study of some infectious causes of reproductive disorders in cattle owned by resource-poor farmers in Gauteng Province, South Africa

2011-05-01

Full Text Available Two hundred and thirty-nine cattle from Gauteng Province in South Africa were tested for various pathogens causing reproductive diseases including bovine viral diarrhoea/mucosal disease (BVD/MD virus, infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV virus, Neospora caninum and Brucella abortus using various tests. For BVD/MD virus, 49.37 % tested positive, 74.47 % for IBR/IPV virus, 8.96 % for Neospora caninum and 3.8 % for Brucella abortus. The result for Brucella abortus is higher than the national average, possibly due to the small sample size. A high seroprevalence of antibodies to both BVD/MD virus and IBR/IPV virus was evident. These 2 viruses should be considered, in addition to Brucella abortus, when trying to establish causes of abortion in cattle. The clinical significance of Neospora caninum as a cause of abortion in Gauteng needs further investigation. One hundred and forty-three bulls were tested for Campylobacter fetus and Trichomonas fetus, and a low prevalence of 1.4 % and 2.1 % respectively was found in this study. The clinical implications of these findings are discussed.

Acute herpes simplex virus (HSV) infection was detected in 23 of 102 consecutively examined, sexually active male homosexuals who presented with anorectal pain, discharge, tenesmus, or hematochezia, as compared with 3 of 75 homosexual men without gastrointestinal symptoms (P less than 0.01). Findings that were significantly more frequent in men with HSV proctitis than in men with proctitis due to other infectious causes included fever (48 per cent), difficulty in urinating (48 per cent), sacral paresthesias (26 per cent), inguinal lymphadenopathy (57 per cent), severe anorectal pain (100 per cent), tenesmus (100 per cent), constipation (78 per cent), perianal ulcerations (70 per cent), and the presence of diffuse ulcerative or discrete vesicular or pustular lesions in the distal 5 cm of the rectum (50 per cent). Serologic evidence indicated that 85 per cent of the men with symptomatic HSV proctitis were having their first episode of HSV-2 infection. The diagnosis of HSV proctitis is suggested by the presence of severe anorectal pain, difficulty in urinating, sacral paresthesias or pain, and diffuse ulceration of the distal rectal mucosa.

Full Text Available Canine atopic dermatitis (CAD is a common dermatosis, defined as a genetic-related disease which predisposes to skin inflammation and pruritus, associated to a IgE-specific response in most of cases. Clinical diagnosis may be later complemented by skin allergy and/or serological tests. The aim of these tests is to identify possible allergens in order to enable the clinicians to select candidate antigens for allergen specific immunotherapy. In the present study 58 CAD positive animals were tested. All were submitted to the intradermal test (IDT and screened for the presence of antibodies against different antigens using ELISA. The obtained results show a high prevalence of sensitization among the tested dogs to house dust mites and to pollen ofC. dactylon. With this work it was possible to identify the main allergens involved in immunological response of dogs with CAD living in central area of Rio Grande do Sul.

Full Text Available Introduction: Cutaneous Larva Migrans is a dermatosis caused by nemantode parasites, mainely Ancylostoma brasiliensis and Ancylostoma caninus. It is an endemic disease in tropical countries but a rare diagnosis in the rest of the world. Case Report: We report the case of a ten-year-old child emigrated from Angola. The physical examination showed scarring injuries from previous incisions made as a form of treatment as well as a serpiginous lesion on the dorsum of the left foot, compatible with cutaneous Larva Migrans. The patient was started on albendazole and complete resolution of symptoms was obtained after one week. About that time, the patient’s brother, who had the same symptoms on both feet, was submitted to the same treatment, also with resolution of symptoms. Discussion: The authors wish to enphasize the relevance of this case due to the migration from countries with high prevalence of cutaneous Larva Migrans.

Full Text Available Prurigo pigmentosa is a rare inflammatory dermatosis that primarily affects adolescents and young adults. Even though it is most commonly seen in Japanese women, other countries have reported cases with increasing frequency. It is characterized by erythematous papules and macules on the trunk, neck and chest that resolve leaving a reticulate hyperpigmentation. Some endogenous factors related with ketosis like fasting, diet, diabetes, pregnancy and exogenous agents like chrome, nickel, para-amino compounds have been accused of playing a role in etiology. Here we would like to present a case of a 16-year-old female patient who was referred to our clinic with pruritic lesions on the trunk and neck, consistent with the initial phase of prurigo pigmentosa, after a period of strict diet. Prurigo pigmentosa is a disease with distinctive histologic and clinical features. Due to its rare occurrence, an accurate diagnosis may be particularly challenging. Clinicopathological correlation is therefore crucial in the diagnosis of the disease in its early phase.

Full Text Available Canine demodicosis is a common noncontagious parasitic dermatosis caused by different spp of Demodex mites including Demodex canis, Demodex injai and D. cornei. Generalized demodicosis can be one of the most frustrating skin diseases, one will ever treat. Conventional and newer miticidal therapies are available to veterinarian to treat this frustrating skin disease. All recognized Demodex mites in dogs appear to respond similarly to mite targeted therapy. Treatment for canine demodicosis includes amitraz, ivermectin, milbemicin oxime, moxidectin, and doramectin. The use of any glucocorticoid-containing products is contraindicated and could favour disease generalization. Conventional treatments will often appear to work however, but it relies heavily on a highly toxic method of treatment. Using natural remedies for mange, on the other hand, can enhance the dog’s immune system, so that the body can fight off the mange mite infection by itself. [Veterinary World 2011; 4(1.000: 41-44

Evaluates the results of examinations carried out in the Belchatow brown coal surface mine on skin diseases. Influence of working conditions specific for brown coal mines on the development of some dermatoses is analyzed. From 1978 to 1979 443 miners were examined. Two groups of miners were examined separately: 1. 235 miners who contacted the firm physician due to skin problems and 2. 208 miners who underwent a periodic examination. In group 1 skin dermatoses were found in 86% of all cases, and in group 2 in 48%. Foot skin inflammation, particularly interdigital intertrigo, was the most common dermatosis. Oil acne (occupational disease of coal miners) was diagnosed in 15 cases, common acne in 23 cases, pytiriasis versicolor in 19 cases, erythrasma in 10, eczema and other contact dermatitis in 10 cases. Investigations show that 23% of the foot interdigital intertrigo is caused by mycotic infections. Dermatoses of the skin of miners' feet are caused mainly by rubber protective boots. (10 refs.)

Metabolomics is a powerful emerging tool for the identification of biomarkers and the exploration of metabolic pathways in a high-throughput manner. As an administration site for percutaneous absorption, the skin has a variety of metabolic enzymes, except other than hepar. However, technologies to fully detect dermal metabolites remain lacking. Skin metabolomics studies have mainly focused on the regulation of dermal metabolites by drugs or on the metabolism of drugs themselves. Skin metabolomics techniques include collection and preparation of skin samples, data collection, data processing and analysis. Furthermore, studying dermal metabolic effects via metabolomics can provide novel explanations for the pathogenesis of some dermatoses and unique insights for designing targeted prodrugs, promoting drug absorption and controlling drug concentration. This paper reviews current progress in the field of skin metabolomics, with a specific focus on dermal drug delivery systems and dermatosis. Copyright © 2016.

A 33-year old pregnant patient (pregnancy week 15) with a past medical history of ulcerative colitis with onset of the disease following the birth of her first child was admitted to the hospital with symptoms of weight loss, pyrexia, leukocytosis and bloody and mucous diarrhoea. Total ileocolonoscopy revealed an acute flare of ulcerative colitis. Within a few days, tender erythematous skin lesions occurred and were histologically proven to be neutrophilic dermatosis. Treatment with highly-dosed prednisone led to a complete remission of both cutaneous and intestinal manifestations. Both pathogenic entities are associated with similar immunological alterations, such as comparable cytokine and chemokine release patterns and recruitment of inflammatory cells. Recent data also indicates that proinflammatory cytokine levels are elevated in pregnancy, which might be pivotal in the pathogenesis and the severity of intestinal and extraintestinal symptoms. We present and discuss a diagnostic algorithm and an overall therapeutic rationale for Sweet's syndrome. Copyright Georg Thieme Verlag KG Stuttgart. New York.

Sweet's syndrome (SS) is a neutrophilic dermatosis disorder of unknown aetiology, characterised by acute fever, neutrophilia, painful erythematous papules, nodules and plaques, and an infiltrate consisting predominantly of mature neutrophils in the upper dermis. Classical SS is a rare extra-intestinal manifestation of inflammatory bowel disease (IBD). It is more common in Crohn's disease than in ulcerative colitis (UC). There is a predilection for women, and for patients with colonic disease and active IBD. We report the case of a 39-year-old woman with a flare of moderate severity UC treated with mesalazine who presented with a 5-day history of acute fever, painful papules and plaques on forearms and legs, episcleritis and cervical pain. Skin biopsies showed papillary dermis inflammatory cell infiltration composed mainly of neutrophils, without evidence of leukocytoclastic vasculitis or panniculitis, compatible with SS. The patient had an excellent response to systemic corticosteroids. Symptoms promptly improved and skin lesions resolved after 7 weeks. 2016 BMJ Publishing Group Ltd.

Pyoderma gangrenosum (PG) is a neutrophilic dermatosis of unknown aetiology. We report a 27-year-old male patient with diabetes, who presented with a nonhealing ulcer on the left leg, pruritic hyperpigmented papules distributed over the trunk and limbs, and chronic diarrhoea. He had eosinophilia, low haemoglobin and serum IgE levels, and raised erythrocyte sedimentation rate. Histopathology of the leg ulcer was consistent with the diagnosis of PG, while the histology of the hyperpigmented papule revealed tissue eosinophilia. Subsequent evaluation was conclusive of the diagnosis of PG, idiopathic hypereosinophilic syndrome (IHES) and selective IgE deficiency. Dexamethasone pulse therapy achieved resolution of the ulcer and reduction in the eosinophilia. Further evaluation for the persistent diarrhoea led to a diagnosis of lymphocytic colitis (LC), which responded to budesonide. To our knowledge, the association of PG with IHES, selective IgE deficiency or LC has not been previously reported. © 2015 British Association of Dermatologists.

Psoriasis is a common chronic inflammatory dermatosis that causes significant distress and morbidity. Approximately 50% of patients with cutaneous psoriasis and 90% of patients with psoriatic arthritis demonstrate nail involvement of their psoriasis. Left untreated, nail psoriasis may progress to debilitating nail disease that leads to not only impairment of function but also on quality of life. We report the case of a 50-year-old male patient with recalcitrant nail dystrophies on the fingers since the age of 40, who responded successfully to Dr. Michaels® product family. The patient had a 35-year history of plaque psoriasis localised on the scalp, ears, groin, limbs, and trunk and with psoriatic arthritis. The nail symptoms consisted of onycholysis, onychomycosis, leukonychia, transverse grooves, nail plate crumbling and paronychia of the periungal skin. This case represents the efficacy and safety of the Dr. Michaels® (Soratinex® and Nailinex®) product family with successful resolution of nail dystrophies and surrounding paronychia with no reported adverse events.

Association of Sweet's Syndrome and Systemic Lupus Erythematosus

Full Text Available Sweet's syndrome is an acute febrile neutrophilic dermatosis which usually presents as an idiopathic disorder but can also be drug induced, associated with hematopoetic malignancies and myelodysplastic disorders, and more, infrequently, observed in autoimmune disorders. Sweet's syndrome has been reported in three cases of neonatal lupus, three cases of hydralazine-induced lupus in adults, and in nine pediatric and adult systemic lupus erythematosus (SLE patients. We describe three additional adult cases of Sweet's associated with SLE and provide a focused review on nondrug-induced, nonneonatal SLE and Sweet's. In two of three new cases, as in the majority of prior cases, the skin rash of Sweet's paralleled underlying SLE disease activity. The pathogenesis of Sweet's remains elusive, but evidence suggests that cytokine dysregulation may be central to the clinical and pathological changes in this condition, as well as in SLE. Further research is needed to define the exact relationship between the two conditions.

443 subjects were examined, 235 applying to the physician due to the occurrence of skin dermatoses (group I) and 208 workers referred for periodic examinations (group II). In group I skin dermatoses were found in 100, i.e. 85%, of the subjects and in group II in 99 i.e. 48% of the subjects. In both groups the most frequent dermatosis was feet skin inflammation, especially interdigital intertrigo. Oil acne was diagnosed in 15, ordinary acne in 23, pityriasis versicolor in 19. erythrasma in 10, and eczema and contact dermatitis in 7 subjects of the first group and 3 subjects of the other group. 204 subjects with feet skin pathologies underwent mycologic examinations and 36 subjects--also bacteriologic examinations. The results of those studies indicate that in 23% of the subjects, feet interdigital intertrigo results from mycologic infections. Bacterial infections may contribute to etiopathogenesis. Imidazole compounds are useful for the treatment and prevention of interdigital intertrigo.

Evaluates the results of examinations carried out in the Belchatow brown coal surface mine on skin diseases. Influence of working conditions specific for brown coal mines on the development of some dermatoses is analyzed. From 1978 to 1979 443 miners were examined. Two groups of miners were examined separately: 1. 235 miners who contacted the firm physician due to skin problems and 2. 208 miners who underwent a periodic examination. In group 1 skin dermatoses were found in 86% of all cases, and in group 2 in 48%. Foot skin inflammation, particularly interdigital intertrigo, was the most common dermatosis. Oil acne (occupational disease of coal miners) was diagnosed in 15 cases, common acne in 23 cases, pytiriasis versicolor in 19 cases, erythrasma in 10, eczema and other contact dermatitis in 10 cases. Investigations show that 23% of the foot interdigital intertrigo is caused by mycotic infections. Dermatoses of the skin of miners' feet are caused mainly by rubber protective boots. (10 refs.)

Full Text Available Many advances in dermatology have been made in recent years. In the present review article, newly described disorders from the last six years are presented in detail. We divided these reports into different sections, including syndromes, autoinflammatory diseases, tumors, and unclassified disease. Syndromes included are “circumferential skin creases Kunze type” and “unusual type of pachyonychia congenita or a new syndrome”; autoinflammatory diseases include “chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE syndrome,” “pyoderma gangrenosum, acne, and hidradenitis suppurativa (PASH syndrome,” and “pyogenic arthritis, pyoderma gangrenosum, acne, and hidradenitis suppurativa (PAPASH syndrome”; tumors include “acquired reactive digital fibroma,” “onychocytic matricoma and onychocytic carcinoma,” “infundibulocystic nail bed squamous cell carcinoma,” and “acral histiocytic nodules”; unclassified disorders include “saurian papulosis,” “symmetrical acrokeratoderma,” “confetti-like macular atrophy,” and “skin spicules,” “erythema papulosa semicircularis recidivans.”

Myelodysplastic Syndromes (MDS) and autoimmune disorders (AD): cause or consequence?

Science.gov (United States)

Braun, Thorsten; Fenaux, Pierre

2013-12-01

Myelodysplastic Syndromes (MDS) and Chronic Myelomonocytic Leukemia (CMML) are frequently associated with clinical manifestations of autoimmune disorders (AD) and inflammatory response of the immune system. AD accompanying MDS and CMML include vasculitis, seronegative polyarthritis and neutrophilic dermatosis. Rare AD including relapsing polychondritis is strongly associated with MDS as in a high proportion of those patients MDS is diagnosed during disease course. Antinuclear antibodies (ANA) are frequently found among MDS patients without clinical manifestation of AD. In a subset of patients, MDS and resulting cytopenias appear to be the consequence of auto reactive immunologic activity and may respond to immunosuppressive treatment (IST). Increased release of inflammatory cytokines like tumor necrosis factor-(TNF)-α and interferon (IF)-γ triggers apoptosis of myeloid precursor cells leading to cytopenias. Impaired function of immune cells including cytotoxic, regulatory (Treg), helper (Th17) T cells and NK cells also appears to predict response to IST, outcome and occurrence of AD.

Confluent and reticulated Papillomatosis of Gougerot and Carteaud - presentation in adolescence

Directory of Open Access Journals (Sweden)

Joana Leite

2015-12-01

Full Text Available Introduction: Confluent and reticulated papillomatosis (CRP of Gougerot and Carteaud is a rare dermatosis characterized by brownish papules with fine scaling, forming confluent plaques in the center and reticulated at the periphery. It is preferentially located in the central region of the trunk, armpits and neck. Case Report: A 13 year-old overweight female adolescent was admitted to Dermatology outpatient clinic for asymptomatic brownish skin lesions. At physical examination she presented brown plaques spread out on the breast, neck and armpits. Laboratory studies were normal and skin biopsy supported the hypothesis of CRP. She was initially treated with minocycline, suspended after completing the recommended treatment time. Then, the lesions began to return and oral isotretinoin was started with lesions resolution. Discussion: The CRP is a rare pathology that, by their usual adolescent onset and predominance in females, may have physical and psychological implications on self-image. The etiology is probably multifactorial, so there are several therapeutic options.

We describe an 8-year-old girl born to second-degree consanguineous parents with complaints of recurrent episodes of hematuria for 6 months. She had generalized peeling of the skin since birth and recurrent purulent cutaneous infections. The clinical presentation and histopathology of the skin biopsy specimen were consistent with the inflammatory variant of peeling skin syndrome (PSS). She also had a single ventricle with pulmonary stenosis, for which a bidirectional Glenn shunt had been placed. The renal biopsy specimen showed immunoglobulin A (IgA) nephropathy. She responded well to enalapril and steroids, with a decrease in proteinuria. IgA nephropathy has not been previously reported in PSS. Complications such as IgA nephropathy in children with PSS would help to further delineate the diverse clinical presentations and the clinical course of this rare dermatosis. We discuss the mechanisms that could explain this hitherto unreported association. © 2014 Wiley Periodicals, Inc.

Full Text Available In view of the frequency of the dermatological manifestations in patients who suffer from AIDS/HIV, and with the objective of describing their behaviour, a descriptive,observational, and cross sectional investigation was carried out in the cases of the AIDS provincial consultation at Ernesto Guevara General Teaching Hospital of Las Tunas from January, 2007 to June, 2008. The information was obtained from the survey, the dermatological examination, and the clinical charts. The sample was made up of 43 patients, in which males and 31 to 40 age groups prevailed. There were no important quantity differences between the seropositive number and AIDS cases. The 27, 9% had dermatosis that made suspect the presence of the chronic retrovirus. The viral and the mycotic diseases were the most frequent ones, being the neoplastic type and drugreactions the least frequent ones. Other sexually transmitted diseases (STD appeared associated to the primary disease, mainly herpes simplex type II, and verruca acuminata.

The retinoids. A review of their clinical pharmacology and therapeutic use.

With the introduction of the synthetic retinoids, oral therapy with an acceptable risk/benefit ratio became possible for a variety of skin diseases including severe acne, psoriasis and numerous genodermatoses. This article reviews the clinical pharmacology, mechanisms of action and therapeutic use of the retinoids, particularly isotretinoin (13-cis-retinoic acid) and etretinate. The free aromatic acid of etretinate, etretin, and the new polyaromatic retinoid compounds (arotinoids) are also discussed. Isotretinoin is used clinically for oral therapy of severe acne, but is also recommended for severe Gram-negative folliculitis and rosacea not responding to traditional therapy. The results of several studies have established that acne therapy should be started with 1.0 mg/kg/day for 2 to 3 months after which the daily dosage should be lowered to 0.2 to 0.5 mg/kg/day for another 2 to 3 months. This therapeutic regimen of isotretinoin has proven to be the most successful in preventing relapses. Etretinate is particularly useful for oral therapy of widespread plaque-like, pustular and erythrodermic psoriasis, and of generalised lichen planus, Darier's disease and severe congenital ichthyoses. Whereas pustular forms of psoriasis require a high daily dosage of 1.0 mg/kg/day, erythrodermic psoriasis should be treated with a lower dosage of 0.25 to 0.35 mg/kg/day. In chronic plaque-like psoriasis, a mean daily dosage of 0.5 mg/kg/day over several weeks to months, usually combined with photo(chemo)therapy, tar or dithranol, is recommended. Other indications for oral etretinate therapy are adequately treated with a moderate dosage of 0.4 to 0.75 mg/kg/day. Etretin differs from etretinate in having a much shorter elimination half-life of 2 to 3 days, in contrast to 80 to 100 days after long term administration of etretinate. Moreover, it has not been shown to increase serum cholesterol levels. However, its clinical efficacy is not yet clearly established. Among the arotinoids

The incidence of the human papilloma virus (HPV) has not dropped in HIV-positive patients despite the discovery of antiretroviral therapy (ART). Our goal is to assess the prevalence of HPV in HIV patients and its relationship with the epidemiological and virological characteristics of HIV patients. Retrospective cohort of 965 patients diagnosed with HIV from 1998 to 2012. We analyzed patients' demographic factors and factors related to the HPV. Of the 965 patients examined, 333 consulted a dermatologist. Of these, 52 patients had genital warts (15.6%), 43 had common warts (12.9%) and 8% had both conditions. In total, 28.5% of patients had a skin lesion caused by HPV. This is the first longitudinal observational study carried out on HIV-positive patients in the era of ART in which HPV infection is the most common skin pathology. We observed a similar trend in countries with access to ART. This study spreads awareness on the importance of preventing HPV and the difficulty of treating it in HIV-positive patients.

EPSTEIN-BARR VIRUS AND CYTOMEGALOVIRUS: IS THEIR ROLE IN PEMPHIGUS REALLY INCIDENTAL? A PRELIMINARY REPORT

Directory of Open Access Journals (Sweden)

N. V. Makhneva

2016-01-01

Full Text Available Background: Epstein-Barr (EBV and cytomegaloviral (CMV infections are among most prevalent in the population worldwide that are associated with autoimmune processes. However, conflicting data of the studies on the role of herpes viral infections in the etiology of autoimmune pemphigus does not allow for reliable recognition of these viruses as triggers in the development and course of this bullous dermatosis. Aim: To assess specific IgM and IgG antibodies to herpes virus infections in patients with autoimmune pemphigus. Materials and methods: Serum samples from 15  patients with autoimmune pemphigus were analyzed by chemoluminescent immunoassay. Results: In the serum samples of 14/15 (93.3% patients with autoimmune pemphigus we found specific IgG antibodies to nuclear and capsid EBV proteins at the levels of 30.7 to 600 U/mL (median, 147.5 [102.62; 313.25] U/mL and from 33.5 to 567 U/mL (median, 186 [85.95; 492.5] U/mL, respectively. Specific IgG antibodies to the EBV early protein were found only in 6.7% of cases. In all patients, there were no specific IgM antibodies to EBV capsule antigens. All patients (100% had specific IgG anti-CMV antibodies in the range from 64.5 to 138 U/mL (median, 103.5 [94.83; 113.75] U/mL. In 30% of cases, there were specific IgM anti-CMV antibodies at titers of 11 to 12.3 U/mL (median, 5 [5; 9.5] U/mL. Conclusion: The results of the preliminary study showed that 93.3%  of autoimmune pemphigus cases have an underlying chronic infection caused by EBV and CMV. The finding of the high titers of IgG anti-EBV and anti-CMV antibodies allows to conclude that the association of these viruses with the bullous dermatosis is not just a chance. It makes further research undoubtedly necessary. Its results would draw more accurate conclusions on the role of EBV and CMV in the pathogenesis of autoimmune pemphigus and to find new perspectives in the treatment of patients with this life-threatening disease.

Full Text Available A total of 25, 4-weeks old, turkey poults were used in the present study. Birds were inoculated by chicken pox virus at the dose of 3 x l07.6/ml. Skin biopsy samples were taken sequentially from the same inoculated bird at 12 and 24 hours and at 2nd, 3rd, 4'h, 5th, 7th, l0th, 14th and 21 days post inoculation (PI. Tissue samples from upper respiratory and digestive tracts were also collected. Pox cytoplasmic inclusions (Bollinger bodies were detected between 4 and 7 days PI in epidermal the cell as well as in the follicular and sinus epithelium. Proliferative and necrobiotic epithelial changes were observed. Thereafter, pox inclusions disappeared with the appearance of vesicular, pustular and ulcerative lesions. This was accompanied by the gradual development of granulation tissue and finally scar tissue formed. Ultrastructure of the inclusion bodies and fine changes of the affected epidermal cell were illustrated.. It was concluded that the inoculated chicken pox virus is highly pathogenic for turkeys. Taking sequential biopsy samples from the same inoculated bird was found to yield more accurate follow up of the pox skin lesions.

Despite great therapeutic advancements in psoriasis, four notable difficult-to-treat areas including the scalp, nails, intertriginous (including genitals), and palmoplantar regions, pose a challenge to both physicians and patients. Localized disease of these specific body regions inflicts a significant burden on patients' quality of life and requires an adequate selection of treatments. Areas covered: This manuscript discusses appropriate therapies and important treatment considerations for these difficult-to-treat areas based on the available clinical data from the literature. Expert opinion: Clinical trials assessing therapies for the difficult-to-treat areas have been inadequate. With the first biological clinical trial for genital psoriasis pending publication, it is with hope that other biological agents will be evaluated for region-specific psoriasis. A greater understanding of the genetic and immunologic aspects of regional psoriasis, as well as identification of unique biomarkers, will further guide management decisions. For example, the recent discovery of the IL-36 receptor gene for generalized pustular psoriasis may prove valuable for other forms of psoriasis. Ultimately, identification of the most beneficial treatments for each psoriasis subtype and difficult-to-treat area will provide patients with maximal quality of life.

The objective of our study was to clarify the radiologic spectrum of disease entities belonging to the SAPHO syndrome (SAPHO being an acronym for synovitis, acne, pustulosis, hyperostosis, and osteitis). A retrospective analysis of radiologic data was undertaken to determine the relationship of the osteoarthritic changes seen in palmoplantar pustulosis (PPP, n = 179), acne (n = 3), psoriasis vulgaris (PsV, n = 355), generalized pustular psoriasis (GPP, n = 25), and chronic recurrent multifocal osteomyelitis (CRMO, n = 4). Osseous changes of PPP, acne, and CRMO overlap each other; 7 PPP, 2 acne, and 3 CRMO patients manifested stenocostoclavicular hyperostosis as well as hyperostosis of the spine, pelvis, and/or femur. These findings were not seen in either PsV or GPP patients. Thirteen PsV and 4 GPP patients had peripheral arthritis and/or symmetrical sacroiliitis, which were not observed in the PPP, acne, and CRMO patients. The PPP, acne, and CRMO patients may be grouped as belonging to the single disease entity, namely SAPHO syndrome. Our findings do not support the inclusion of PsV and GPP in the spectrum of this syndrome. (orig.) With 7 figs., 2 tabs., 30 refs.

Full Text Available For centuries morbillivirus infections have had a huge impact on both human beings and animals. Morbilliviruses are highly contagious pathogens that cause some of the most devastating viral diseases of humans and animals world wide. They include measles virus (MV, canine distemper virus (CDV, rinderpest virus (RPV and peste des petits ruminants (PPRV virus. Furthermore, new emerging infectious diseases of morbilliviruses with significant ecological consequences of marine mammals have been discovered in the past decades. Phocid distemper virus (PDV in seals and the cetacean morbillivirus (CMV have been found in dolphins, whales and porpoises. Peste des petits ruminants (PPR is a highly contagious ,infectious , an acute or sub acute viral disease of domestic and wild small ruminants characterized by fever, oculonasal discharges, stomatitis, conjunctivitis, gastroenteritis and pneumonia. Goats are more severely affected than sheep. It is also known as pseudorinderpest of small ruminants, pest of small ruminants, pest of sheep and goats, kata, stomatitis- pneumoentritis syndrome, contagious pustular stomatitis and pneumoentritis complex. It is one of the major notifiable diseases of the World Organization for Animal Health (OIE. [Vet. World 2009; 2(4.000: 150-155

Full Text Available From 1981 to 1992, 109 cases (90 females and 19 males of pemphigus were seen in the Department of Dermatology, Central Hospital Tripoli, Libya. Age of onset of the disease varied from 17 to 85 years, while duration of the disease at the time of presentation varied from 3 days to 13 days. On the basis of clinical features and routine histological findings the cases were divided into various subtypes as : pemphigus foliaceus 65 cases, pemphigus vulgaris 34 patients, pemphigus erythematosus 5, herpetiform pemphigus 3 and vegetans type 2 cases. Three of our patients had diabetes mellitus preceding pemphigus, while 12 patients developed steroid induced diabetes. Significant secondary bacterial infection occurred in all cases at some stage of the disease while oral candidiasis occurred in 15 cases. Eczema herpeticum was seen in 4 patients, while 2 had extensive tinea corporis. One of 4 patients of pemphigus vulgaris had complete shedding of nail and 1 female patient had alternate phases of pemphigus foliaceus and generalized pustular psoriasis. The features in our cases of pemphigus foliaceus were somewhat similar to Brazilian pemphigus foliaceus and we had more cases of pemphigus foliaceus, almost exclusively affecting females.

Impetigo herpetiformis is a rare pustular eruption with usual onset during the third trimester of pregnancy. The disease tends to remit after delivery, but may recur in subsequent pregnancies. Here we present a recurrent case of impetigo herpetiformis with earlier onset and poor response to corticosteroids in the subsequent pregnancy. She had widespread, erythematosquamous patches with tiny superficial pustules in the third trimester of her first pregnancy. Histopathological and clinical findings were consistent with impetigo herpetiformis. She was treated with systemic prednisolone and had a healthy baby without any complication. Three years later, the patient presented with impetigo herpetiformis again in the second trimester of her second pregnancy. After six weeks of oral prednisolone treatment, the lesions improved, but there were still new pustule formations and narrowband ultraviolet B treatment was added. Skin eruption cleared and she had a healthy baby in the 38th week of her second pregnancy. The corticosteroid dose was tapered gradually and stopped after delivery. Early diagnosis and treatment is crucial in impetigo herpetiformis because of the risk of maternal and fetal complications. When prednisolone is not enough to control the eruption alone, narrowband UVB can safely be added to the treatment.

Nocardia are ubiquitous, aerobic, gram-positive actinomycetes. Nocardiosis typically occurs in immunocompromised patients, although immunocompetent individuals can also be affected. The purpose of this case study is to review the clinical characteristics and treatments of a unique form of cutaneous nocardiosis. We retrospectively reviewed the medical literature using PubMed, searching the terms cutaneous, host, immunocompromised, Nocardia, primary, yamanashiensis. Patient reports and previous reviews of the subject were critically assessed and the salient features are presented. Cutaneous nocardiosis typically presents as pustular nodules and the lesions may progress to become abscesses, cellulitis, granulomas or keloid-like tumors. N. brasiliensis is the predominant species involved in primary cutaneous nocardiosis; other common Nocardia species involved in human disease are N. farcinica, N. abscessus, N. cyriacigeorgica, and N. nova. Only two individuals (including the patient presented here) with primary cutaneous infection by N. yamanashiensis have been described in the literature; a third clinical isolate was recovered from a lung biopsy. Nocardia yamanashiensis is a rare clinical form of primary cutaneous nocardiosis. 16S ribosomal gene sequencing, as well as Gram stain and modified Fite acid-fast stain, play a vital role in identifying this clinical variant.

Localization of Haemophilus ducreyi in naturally acquired chancroidal ulcers.

Haemophilus ducreyi causes the sexually transmitted genital ulcer disease chancroid. In human inoculation experiments, bacteria colocalize with neutrophils and macrophages but remain extracellular. The organism also colocalizes with collagen and fibrin but not with keratinocytes, fibroblasts, laminin, or fibronectin. These relationships are established by 48 h postinoculation and persist through the pustular stage of disease. To extend these observations to the ulcerative stage of disease, and to compare results in the human model with those of natural disease, we obtained biopsies from patients with naturally acquired chancroid. All ulcers were culture positive for H. ducreyi and histologically very similar to pustules from the human model. Staining with H. ducreyi-specific monoclonal antibodies demonstrated H. ducreyi within 5 biopsies. The organism was chiefly found within the granulocytic infiltrate of the ulcer. Dual staining for H. ducreyi and eukaryotic tissue components showed that H. ducreyi colocalized with neutrophils and fibrin at the ulcerative stage of disease. No bacteria were associated with keratinocytes, fibroblasts, or collagen. Overall, these findings are consistent with results from the human model. This is the first reported study to localize bacteria specifically identified as H. ducreyi within naturally acquired chancroid.

2008-01-01

Full Text Available Background: Kyrle′s disease is a rare variant of primary perforating dermatosis. Its occurrence in a familial setting, especially in children, is extremely uncommon. Similar appearing skin lesions have been described in adults, secondary to metabolic disorders, infective agents as well as exposure to chemicals. We present a rare case of this genodermatosis in two siblings. Materials and Methods: Two siblings of a non-consanguineous marriage came with generalized discrete papular lesions with a central keratotic plug. All biochemical and serological investigations were within normal limits. Serial sections of the biopsy revealed typical epidermal invaginations filled with parakeratotic debris and perforation into the dermis with accompanying granulomatous reaction. Results and Conclusions: A careful history, detailed routine investigations and serial sections of the skin biopsy are required to demonstrate the typical morphology and stages of evolution of Kyrle′s disease. This helps to differentiate the rare primary Kyrle′s disease from other primary and secondary keratotic lesions. Due to the familial occurrence, screening of relatives of an index case is recommended.

The aim of the present study was to determine the factors affecting the prevalence of mange-mite infestations in stray dogs of Yucatán, Mexico. The study was carried out in 200 stray dogs of Mérida capital city of Yucatán, Mexico. Four samples (head, thoracic-abdominal area, extremities and ear) were taken from each animal by skin scraping and examined microscopically in 10% KOH solution to detect the presence of mites. Mites were also collected from the external ear canal of dogs using cotton-tipped swabs. The prevalence of different mite species was calculated. A primary screening was performed using 2xK contingency tables of exposure variables. All variables with PDemodex canis (23.0%) was the most frequent mite, followed by Sarcoptes scabei var. canis (7.0%) and Otodectes cynotis (3.5%). The following factors were found: body condition (bad, OR: 5.35, CI 95%: 1.66-17.3; regular, OR: 3.72, CI 95%: 1.39-9.99) and the presence of macroscopic lesions of dermatosis (OR: 42.80, CI 95%: 13.65-134.24).

Pyoderma gangraenosum is an immune-mediated, inflammatory, neutrophilic dermatosis of unknown etiology, which represents one of the extraintestinal manifestations of inflammatory bowel disease. It is a rare disease that occurs in less than 1% of patients with inflammatory bowel disease and with the same ratio in patients with Crohn's disease and ulcerative colitis. A 36-year-old woman was diagnosed with ulcerative colitis 6 years before admission to our dermatology department with an acute disseminated pyoderma gangraenosum with mucosal involvement, during a flare of ulcerative colitis. Disease progression was interrupted by intravenous administration of the tumor necrosis factor-α inhibitor infliximab at 5 mg/kg at weeks 0, 2, and 6 (1st cycle) and every 8 weeks thereafter. Improvement of intestinal, skin and oral manifestations was evident already after the 1st cycle of treatment and has been maintained since (at least 16 months). This case report is one of very few on disseminated pyoderma gangraenosum with oral involvement complicating ulcerative colitis, where infliximab was shown to have a rapid efficacy on skin, mucosal and bowel symptoms.

Sweet syndrome (acute, febrile, neutrophilic dermatosis) is characterized by the acute onset of an eruption of painful nodules or erythematous or violaceous plaques on the limbs, face and neck. These symptoms are accompanied by fever. The diagnostic features include histopathological findings of dermal neutrophilic infiltration without leukocytoclastic vasculitis or peripheral blood leukocytosis. Sweet syndrome is associated with infection, malignancies, autoimmune disease, pregnancy, and drugs. Patients with Sweet syndrome demonstrate a complete and rapid response to systemic steroid administration. Recently, a distinct variant of Sweet syndrome was reported, termed "histiocytoid Sweet syndrome", in which the infiltration of myeloperoxidase-positive histiocytoid mononuclear cells are observed (in contrast to the infiltration of neutrophils). The other clinical features are similar to those of classic Sweet syndrome. Pediatric Sweet syndrome is uncommon, and the histiocytoid type is even rarer. To date, four cases of histiocytoid Sweet syndrome have been reported in children. Herein, we describe a case of histiocytoid Sweet syndrome in an otherwise healthy 10-year-old boy with no underlying systemic disease in whom non-steroidal, anti-inflammatory drug treatment was successful.

Sweet syndrome is a neutrophilic dermatosis that may be categorized into classic, malignancy-associated, and drug-induced subtypes. Few studies have systematically analyzed this rare disorder. To describe the clinicopathologic characteristics and treatment of Sweet syndrome and identify characteristics associated with concurrent malignancy. We retrospectively reviewed patients with Sweet syndrome at the University of Pennsylvania from 2005 to 2015. We identified 83 patients (mean age, 57 years; 51% male) with Sweet syndrome: 30% with the classic form, 44% with the malignancy-associated form, 24% with the drug-induced form in the setting of malignancy, and 2% with the drug-induced form. Acute myeloid leukemia was the most common malignancy (in 24 of 83 patients [29%]). Filgrastim was the most common medication (used in 8 of 83 patients [10%]). Leukopenia (P Sweet syndrome, dermatologists should be aware of the potential association of leukopenia, anemia, thrombocytopenia, absence of arthralgia, and histiocytoid or subcutaneous histopathology with malignancy.

Monogenic Interferon (IFN)-mediated autoinflammatory diseases present in infancy with systemic inflammation, an IFN-response-gene-signature (IRS), inflammatory organ damage and high mortality. We used the janus kinase (JAK) inhibitor baricitinib with IFN-blocking activity in vitro, to ameliorate disease. Between October 2011 and February 2017, 10 patients with CANDLE (chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperatures), 4 with SAVI (Stimulator of IFN genes (STING)-associated vasculopathy with onset in infancy), and 4 patients with other interferonopathies were enrolled in an Expanded Access Program. Patients underwent dose-escalation, benefit was assessed by reductions in daily disease symptoms and corticosteroid requirement. Quality-of-life, organ inflammation, changes in IFN-induced biomarkers, and safety were longitudinally assessed. 18 patients were treated for a mean duration of 3.0 years (1.5-4.9 years). The median daily symptom score decreased from 1.3 (IQR 0.93-1.78) to 0.25 (IQR 0.1-0.63) (P Eli Lilly. Eli Lilly is the sponsor of the compassionate use program.

Full Text Available Lichen planus is a pruritic, benign, papulosquamous, inflammatory dermatosis of unknown etiology that affects either or all of the skin, mucous membrane, hair and nail. In its classic form, it presents with violaceous, scaly, flat-topped, polygonal papules. A female patient aged 43 years with a history of pruritic eruptions for a period of one month over the right armpit and back of the right chest (C8, T1, T2, T3 Dermatomes. She had a history of herpes zoster in the same localization, which had been treated with topical and oral acyclovir two months prior to this visit. This variant may represent as an example of the Wolf’s isotopic response. We presented our case because of its rarity as a Dermatomal distribution of lichen planus pigmentosus (LPP and its appearance in the area of healed herpes zoster as an isotopic response. The case well highlights this unusual condition and represents the first case reported in Indian dermatology literature to our best of knowledge. The clinical and histological features of this case are described here.

Sinonasal Melioidosis in a Returned Traveller Presenting with Nasal Cellulitis and Sinusitis

2013-01-01

Full Text Available We illustrate a case involving a 51-year-old man who presented to a tertiary hospital with sepsis secondary to an abscess of the nasal vestibule and pustular eruptions of the nasal mucosa. Associated cellulitis extended across the face to the eye, and mucosal thickening of the sinuses was seen on computed tomography. The patient underwent incision and drainage and endoscopic sinus surgery. Blood cultures and swabs were positive for a gram-negative bacillus, Burkholderia pseudomallei. He had multiple risk factors including travel to an endemic area. The patient received extended antibiotic therapy in keeping with published national guidelines. Melioidosis is caused by Burkholderia pseudomallei, found in the soil in Northern Australia and Asia. It is transmitted via cutaneous or inhaled routes, leading to pneumonia, skin or soft tissue abscesses, and genitourinary infections. Risk factors include diabetes, chronic lung disease, and alcohol abuse. It can exist as a latent, active, or reactivated infection. A high mortality rate has been identified in patients with sepsis. Melioidosis is endemic in tropical Northern Australia and northeastern Thailand where it is the most common cause of severe community-acquired sepsis. There is one other report of melioidosis in the literature involving orbital cellulitis and sinusitis.

Orf virus interferes with MHC class I surface expression by targeting vesicular transport and Golgi

2012-07-01

Full Text Available Abstract Background The Orf virus (ORFV, a zoonotic Parapoxvirus, causes pustular skin lesions in small ruminants (goat and sheep. Intriguingly, ORFV can repeatedly infect its host, despite the induction of a specific immunity. These immune modulating and immune evading properties are still unexplained. Results Here, we describe that ORFV infection of permissive cells impairs the intracellular transport of MHC class I molecules (MHC I as a result of structural disruption and fragmentation of the Golgi apparatus. Depending on the duration of infection, we observed a pronounced co-localization of MHC I and COP-I vesicular structures as well as a reduction of MHC I surface expression of up to 50%. These subversion processes are associated with early ORFV gene expression and are accompanied by disturbed carbohydrate trimming of post-ER MHC I. The MHC I population remaining on the cell surface shows an extended half-life, an effect that might be partially controlled also by late ORFV genes. Conclusions The presented data demonstrate that ORFV down-regulates MHC I surface expression in infected cells by targeting the late vesicular export machinery and the structure and function of the Golgi apparatus, which might aid to escape cellular immune recognition.

Molecular Genetic Analysis of Orf Virus: A Poxvirus That Has Adapted to Skin

Directory of Open Access Journals (Sweden)

Stephen B. Fleming

2015-03-01

Full Text Available Orf virus is the type species of the Parapoxvirus genus of the family Poxviridae. It induces acute pustular skin lesions in sheep and goats and is transmissible to humans. The genome is G+C rich, 138 kbp and encodes 132 genes. It shares many essential genes with vaccinia virus that are required for survival but encodes a number of unique factors that allow it to replicate in the highly specific immune environment of skin. Phylogenetic analysis suggests that both viral interleukin-10 and vascular endothelial growth factor genes have been “captured” from their host during the evolution of the parapoxviruses. Genes such as a chemokine binding protein and a protein that binds granulocyte-macrophage colony-stimulating factor and interleukin-2 appear to have evolved from a common poxvirus ancestral gene while three parapoxvirus nuclear factor (NF-κB signalling pathway inhibitors have no homology to other known NF-κB inhibitors. A homologue of an anaphase-promoting complex subunit that is believed to manipulate the cell cycle and enhance viral DNA synthesis appears to be a specific adaptation for viral-replication in keratinocytes. The review focuses on the unique genes of orf virus, discusses their evolutionary origins and their role in allowing viral-replication in the skin epidermis.

Orf virus IL-10 reduces monocyte, dendritic cell and mast cell recruitment to inflamed skin.

Orf virus (ORFV) is a zoonotic parapoxvirus that causes pustular dermatitis of sheep, and occasionally humans. Despite causing sustained infections, ORFV induces only a transient increase in pro-inflammatory signalling and the trafficking of innate immune cells within the skin seems to be impaired. An explanation for this tempered response to ORFV infection may lie in its expression of a homolog of the anti-inflammatory cytokine, interleukin (IL)-10. Using a murine model in which inflammation was induced by bacterial lipopolysaccharide, we examined the effects of the ORFV-IL-10 protein on immune cell trafficking to and from the skin. ORFV-IL-10 limited the recruitment of blood-derived Gr-1(int)/CD11b(int) monocytes, CD11c(+ve)/MHC-II(+ve) dendritic cells and c-kit(+ve)/FcεR1(+ve) mature mast cells into inflamed skin. ORFV-IL-10 also suppressed the activation of CD11c(+ve)/MHC-II(+ve) dendritic cells within the skin, reducing their trafficking to the draining lymph node. These findings suggest that expression of IL-10 by ORFV may contribute to the impaired trafficking of innate immune cells within infected skin. Copyright © 2015 Elsevier B.V. All rights reserved.

Full Text Available Psoriasis is an inflammatory skin disease. Five classic types of psoriasis have been defined: plaque, inverse, pustular, guttate, and erythrodermic. The early psoriasis immunologic skin immune response is not well understood. Here we aim to show an immune and cell signaling response in a case of early psoriasis. A 56 year old female presented with a desquamative lesion on her right leg. A skin biopsy for hematoxylin and eosin (H&E and immunohistochemistry (IHC staining was taken. The diagnosis indicated early psoriasis, and IHC showed positive IgD staining in the epidermal corneal layer, as well as positive staining with ribosomal protein S6-pS240 (RIBO in the hyperproliferative epidermis. Cyclooxygenase-2 (COX-2 was also very positive in the granular layer in spots, at the basement membrane zone of the skin and in the inflammatory infiltrate in the dermis subjacent to hyperproliferative psoriatic areas. In an early case of psoriasis, we confirmed the presence of IgD, RIBO and COX-2. Each molecule seems to be playing a role in inflammation and intracellular signaling pathways in early psoriasis. The role of IgD is unknown, and this case brings to light the complexity of the pathologic changes occurring in early psoriatic lesions.

Full Text Available Impetigo herpetiformis (IH, if left untreated, is associated with a high rate of perinatal morbidity and mortality and may lead to the decision of termination of pregnancy. There are various and effective therapeutic agents available for the treatment of the disease. A 23-year-old woman with a history of plaque psoriasis presented with a sudden generalized pustular eruption on the 25th week of her first gestation. The diagnosis was made based on the clinical and histopathological findings. The patient was treated with systemic prednisolone (2 mg/kg/d first and, cyclosporine A (3 mg/kg/d was added to the treatment after two weeks because prednisolone was not effective alone. The lesions did not regress despite four weeks of combined treatment with prednisolone and cyclosporine. Intravenous immunoglobuline (IVIG (0.3 g/kg/d, 6 days was added on the 30th week of gestation and resulted in regression of cutaneous rashes. On the 33rd week of gestation, IVIG (0.7 g/kg/d, 3 days was repeated due to reactivation of pustules, and an improvement was observed. In this case report, we called attention to IVIG therapy in IH, for having the pregnancy continued enough for the fetal maturation before the delivery.

Full Text Available ABSTRACT In order to study and characterize the lesions in the reproductive tract of Nellore heifers naturally infected with Ureaplasma diversum and presenting granular vulvovaginitis syndrome (GVS, fragments of uterine tube, uterus, cervix, vagina and vulva of 20 animals were evaluated. The macroscopic lesions of the vulvovaginal mucosa were classified in scores of “1” mild, until “4”, severe inflammation and pustular or necrotic lesions. The histopathological evaluation was performed using scores of “1” to “4”, according to the inflammatory alterations. The fragments with severe microscopic lesions (3 and 4 were from the uterine tubes and uterus, which showed leukocytes infiltration and destruction and/or necrosis of epithelium. Alterations in the lower reproductive tract fragments were mild, but characteristics of acute inflammatory processes. The histopathological findings of the reproductive tract of females naturally infected with Ureaplasma diversum are consistent with injuries that compromise the environment from the local where spermatozoa acquires ability to fertilize an oocyte until those where the oocyte is fertilized. Therefore, animals with GVS should be identified early in the herd, because, besides the reduction in the fertility rates caused by tissue damages, they can contribute to disseminate the microorganism. Key words: bovine, tissue evaluation, reproduction, Ureaplasma diversum.

Acute generalized exanthematous pustulosis (AGEP) is a disease characterized by the rapid occurrence of many sterile, nonfollicular pustules usually arising on an oedematous erythema often accompanied by leucocytosis and fever. It is usually attributed to drugs. To evaluate the risk for different drugs of causing AGEP. A multinational case-control study (EuroSCAR) conducted to evaluate the risk for different drugs of causing severe cutaneous adverse reactions; the study included 97 validated community cases of AGEP and 1009 controls. Results Strongly associated drugs, i.e. drugs with a lower bound of the 95% confidence interval (CI) of the odds ratio (OR) > 5 were pristinamycin (CI 26-infinity), ampicillin/amoxicillin (CI 10-infinity), quinolones (CI 8.5-infinity), (hydroxy)chloroquine (CI 8-infinity), anti-infective sulphonamides (CI 7.1-infinity), terbinafine (CI 7.1-infinity) and diltiazem (CI 5.0-infinity). No significant risk was found for infections and a personal or family history of psoriasis (CI 0.7-2.2). Medications associated with AGEP differ from those associated with Stevens-Johnson syndrome or toxic epidermal necrolysis. Different timing patterns from drug intake to reaction onset were observed for different drugs. Infections, although possible triggers, played no prominent role in causing AGEP and there was no evidence that AGEP is a variant of pustular psoriasis.

2016-10-01

Salicylic acid (SA) has been frequently used as a facial chemical peeling agent (FCPA) in various cosmetics for facial rejuvenation and dermatological treatments in the clinic. However, there is a tradeoff between therapeutic effectiveness and possible adverse effects caused by this agent for cosmetologists. To optimize the cosmetic efficacy with minimal concentration, we proposed a chemical permeation enhancer (CPE) azone to synergistically work with SA on human skin in vivo. The optical properties of human skin after being treated with SA alone and SA combined with azone (SA@azone) were successively investigated by diffuse reflectance spectroscopy (DRS) and optical coherence tomography (OCT). Our results revealed that as the SA concentration increased, the light reflectance decreased and the absorption increased. We also found that SA@azone exhibited a synergistic effect on enhancing light penetration and OCT imaging depth. We demonstrated that the combination of DRS and OCT techniques could be used as a noninvasive, rapid and accurate measurement method to monitor the subtle changes of skin tissue after treatment with FCPA and CPE. The approach will greatly benefit the development of clinical cosmetic surgery, dermatosis diagnosis and therapeutic effect inspection in related biomedical studies.

Hayani, Kinan; Dandashli, Anwar; Weisshaar, Elke

2015-01-01

Cutaneous leishmaniasis (CL) is a worldwide disease caused by an infection with the protozoan parasite Leishmania transmitted via sand flies. It is endemic in many of the poorest countries of all continents. "Aleppo boil" is one of the recognised names given to this disease in the medical literature. Although CL used to be well-controlled and well-documented in Syria, its incidence has dramatically increased since the beginning of the war; however, there is lack of documentation. Here, we present the past and current epidemiological situation of the disease in Syria. We also draw attention to gross and highly unusual clinical variants of CL presented to the Department of Dermatology in Aleppo covering the important differential clinical diagnoses, since this disease is already known to mimic other conditions. Diagnostic procedures and treatment as well as prevention are summarised. Due to the increased ability to travel, and especially the flight of Syrians to neighbouring countries, as well as to Europe, CL may become a new threat in formerly unaffected regions. Through this account, we hope to give weight to the aspiration that CL does not remain a neglected and often clinically overlooked tropical dermatosis.

2016-01-01

Sweet's syndrome is rare acute febrile neutrophilic dermatosis whose onset is either idiopathic or associated with other underlying conditions, such as infections, autoimmune diseases, pregnancy, use of certain medications, or malignancy. We report the case of a young male with known history of ulcerative colitis and abrupt onset of high fever, malaise, blurred vision and eruption of painful erythematous nodules and papules, localized on the head, neck, trunk and upper limbs. Ophthalmological examination established the diagnosis of anterior uveitis. Inflammatory markers were positive. Histological examination of skin lesions revealed a dense neutrophilic infiltrate of the dermis. Clinical, laboratory and histological findings were suggestive for the diagnosis of Sweet's syndrome and uveitis on a background of ulcerative colitis. Systemic and ophthalmic administration of corticotherapy leads to a prompt resolution of symptoms and inflammatory syndrome. The particularity of this case is the occurrence of two simultaneous extraintestinal manifestations in a young male with inflammatory bowel disease and colonic involvement. Although a relatively rare condition, Sweet's syndrome should be considered as a differential diagnosis in patients with acute onset of high fever and skin rash, as it may have notable internal involvement and can be easily treated.

Steven johnsons syndrome and toxic epidermal necrolysis: A review

Sri ram Anne

2014-12-01

Full Text Available Toxic epidermal necrolysis (TEN and Stevens Johnson Syndrome (SJS are severe adverse cutaneous drug reactions that predominantly involve the skin and mucous membranes. They are characterized by mucocutaneous tenderness and typically hemorrhagic erosions, erythema and more or less severe epidermal detachment presenting as blisters and areas of denuded skin. Drugs are assumed or identified as the main cause of SJS/TEN in most cases, but Mycoplasma pneumoniae and Herpes simplex virus infections are well documented causes alongside rare cases in which the etiology remains unknown. Several drugs are at "high" risk of inducing TEN/SJS including: Allopurinol, Trimethoprim-sulfamethoxazole and other sulfonamide-antibiotics, aminopenicillins, cephalosporins, quinolones, carbamazepine, phenytoin, phenobarbital and NSAID's of the oxicam-type. Differential diagnosis includes linear IgA dermatosis and paraneoplastic pemphigus, pemphigus vulgaris and bullous pemphigoid, acute generalized exanthematous pustulosis (AGEP, disseminated fixed bullous drug eruption and staphyloccocal scalded skin syndrome (SSSS. Due to the high risk of mortality, management of patients with SJS/TEN requires rapid diagnosis, identification and interruption of the culprit drug, specialized supportive care ideally in an intensive care unit, and consideration of immunomodulating agents such as high-dose intravenous immunoglobulin therapy.

Full Text Available Cheyletiellosis (cheyletiella dermatitis is a dermatitis caused by cheyletiella mites that are seen more commonly in cats, dogs and rabbits all over the world. Cheyletiella blakei, which is naturally hosted by cats, causes infestations in people, especially who are in close contact with infested cats. The diagnosis of cheyletiellosis in humans is established by the suspicion of physician or veterinarian and demonstration of the mites in cats. If not suspected, cheyletiellosis may be thought as delusions of parasitosis and may be undiagnosed. A 48-year-old woman presented to our clinic with red, pruritic papules on the chest, abdomen, arms and anterior thighs. There was no remission of the complaints of the patient after 3 days of topical corticosteroid treatment. Following more detailed examination and medical history, cheyletiellosis was suspected. The diagnosis was confirmed by a veterinary control of the cat that the women had started feeding at home about 15 days ago. Although cheyletiella dermatitis is not uncommon, most cases are undiagnosed because it is not a well-known dermatosis by dermatologists. As far as we know, there is no previously reported cheyletiella case in our country. (Turk­derm 2011; 45: 213-5

A controlled and randomized clinical therapeutical assay in phase III was carried out in 52 patients with vulgar psoriasis, who were assisted in the Dermatology department of 'Dr Joaquin Castillo Duany' Clinical Surgical Hospital in Santiago de Cuba, from 2005 to 2010 who were divided into 2 groups (26 members each): the active group which was conventionally treated with 20% cade ointment; and the experimental group, to which the extremely low frequency electromagnetic field was applied, with the objective of determining the effectiveness of this field in those affected during the periods of crisis and intercrisis. The studied population was clinically characterized by means of a frequency analysis, while the hypothesis tests were used for the evaluation of proportions which null hypothesis were accepted with 5 % as maximum error. In the series the used field was effective to treat the disorder during crisis and more effective than the cade ointment to prolong the intercrisis stage, without causing adverse reactions, so that it constituted a new alternative therapy that can be generalized in the dermatological services of the country, in order to improve the life quality of those who suffer that dermatosis

Human dermatophytic cutaneous infections usually present as single or multiple slowly progressing annular erythemato-squamous lesions with a tendency to central healing on the hairless skin. In the intertriginous regions (feet, inguinal, axillar, submammary), dermatophytic colonisations and infections manifest as whitish, slightly hyperkeratotic, pruritic and sometimes fissurated lesions. On the scalp, dermatophytic infections commonly lead to single or multiple more or less inflammatory and alopecic lesions. On the plantar and palmar aspects of the feet and hand, dermatophytosis presents as an eczema-like chronic dermatosis. Abscess-like lesions may occur due to zoophilic dermatomycosis. Dermatophytic infections of the nails reveal ill-defined whitish-yellowish colorations of the distal end or the lateral aspects of the nails, sometimes combined with partial nail embrittlement or even complete destruction. Despite the ubiquity of dermatophytic skin infections and their usually highly typical clinical features, a differential diagnosis has to be considered, in particular when treatment is not efficient or when treatment resistance occurs. This review presents the differential diagnosis in terms of frequency as well as the diagnostic methods permitting the distinction of annular, intertriginous, alopecic, palmoplantar, abscess-like and onychodystrophic lesions.

Full Text Available The association of lichen planus (LP with liver diseases is now well established. Recent reports suggest that the hepatitis viruses may play a central role in this association. Lichen planus following hepatitis B vaccination is much more unusual. A 19-year-old previously healthy male developed itchy violaceous papules and plaques over the upper extremities eight to ten days after the first injection of hepatitis B vaccine. He developed similar lesions over the upper trunk, neck and lower leg after the second and third injections. A skin biopsy showed a lichenoid tissue reaction. Direct immunofluorescence (DIF showed multiple colloid bodies and a strong continuous ragged basement membrane zone (BMZ band with fibrinogen. HbsAg by ELISA and anti-HCV antibodies were negative. The patient was treated with oral steroids and the lesions improved. LP is a pruritic inflammatory dermatosis of unknown origin. An increased prevalence of liver disease in patient with LP has been reported. Since the first case reported by Rebora in 1990, about 15 cases of LP occurring after hepatitis B vaccination have been reported in the literature irrespective of the type of vaccine used.

Full Text Available A condição conhecida como Síndrome de Behçet foi inicialmente descrita por H. Behçet, um dermatologista turco. O seu componente principal são lesões aftosas recorrentes em mucosa oral. Grupos como os asiáticos são mais propícios ao seu desenvolvimento. No continente americano, ela é relativamente rara. Além de lesões orais, os pacientes podem desenvolver ulcerações genitais, uveítes, vasculite pustular da pele, sinovites e meningoencefalites. O diagnóstico é baseado na pronunciação de critérios maiores e/ou menores internacionalmente propostos, e na combinação entre eles. O tratamento é desafiador, devendo dirigir-se ao principal órgão envolvido, exigindo terapias combinadas com freqüência. O quadro clínico do paciente deste caso não deixa dúvidas quanto ao diagnóstico da síndrome de Behçet. No presente trabalho, a vasculite é evidenciada pela ausência de sangramento ao manueseio de áreas potencialmente sangrantes. E a ela atribuiu-se tanto o desencadeamento quanto as complicações da rinossinusite (abscesso periorbitário, haja visto seus efeitos de má perfusão e drenagem no tecido em questão. A rinossinusite é uma manifestação potencial da síndrome de Behçet.

Full Text Available We present a description of the clinical case of a patient with an erythematotelangiectatic type of rosacea. Rosacea is a chronic recurrent dermatosis, characterized by skin lesions of the face in the  form of erythema and papulopustular elements, which has  polyethological origin. The disease occurs more frequently in women  aged 30-50 years who have a certain genetic predisposition to  transient reddening of the skin of the face or less often of the neck  and the decollete zone. It is believed that the dermatosis is more  likely to affect the I and II phototypes, but the disease can occur in  any skin phototype. The patient came to the clinic with complaints  about rashes in the chin and nasolabial triangle, flushing of the face,  accompanied by tingling and burning. The patient turned to the clinic with complaints about rashes in the chin and nasolabial triangle,  flushing of the face, accompanied by tingling and burning. She never consulted a dermatologist before. A diagnosis was made: “erythematotelangiectatic type of rosacea” (according to the  classification proposed by the USA National Rosacea Society, stage I  — persistent erythema and telangiectasia. Using the scale of diagnostic evaluation of rosacea, it was evaluated at 12 points.  There are many approaches to the treatment of rosacea. Drug  therapy is divided into systemic, external and complex. Systemic therapy has a number of side effects, so for light and medium-to- severe rosacea, only external therapy is more often prescribed.  Because of the presence of pathologically altered vessels, the low  efficacy of metronidazole, the patient was assigned a course of  phototherapy with intense incoherent pulsating light at standard  parameters. There was a significant improvement after two  procedures, but vessels smaller than 0.4 mm remained intact, so the duration of the first pulse was increased in order to influence small- caliber vessels

The emergence of the IL-36 cytokine family as novel targets for inflammatory diseases.

Science.gov (United States)

Walsh, Patrick T; Fallon, Padraic G

2018-04-01

The recently discovered interleukin (IL)-36 family of cytokines form part of the broader IL-1 family and are emerging as important mediators of inflammatory disease. The IL-36 subfamily consists of three ligands-IL-36α, IL-36β, and IL-36γ-and the natural antagonist IL-36Ra. The cytokines exert their effects through a specific IL-36 receptor consisting of IL-36R and IL-1RAcP chains. IL-36 cytokines can direct both innate and adaptive immune responses by acting on parenchymal, stromal, and specific immune cell subsets. In humans, inactivating mutations in the gene encoding the IL-36R antagonist, which lead to unregulated IL-36R signaling, lead to an autoinflammatory condition termed deficiency of the IL-36R antagonist, which primarily manifests as a severe form of pustular psoriasis. While such discoveries have prompted deeper mechanistic studies highlighting the important role of IL-36 cytokines in psoriatic skin inflammation, it is now evident that IL-36 cytokines can also play important roles in inflammatory disorders in other organs, such as the gastrointestinal tract and the lungs. Given these emerging roles, strategies to specifically target the expression and activity of the IL-36 family have the potential to uncover novel therapeutic approaches aimed at treating inflammatory diseases in humans. © 2016 New York Academy of Sciences.

Familial Mediterranean fever (FMF) is a genetic disease, characterized by attacks of fever, arthritis, serositis and pain. Behçet's disease (BD) is an inflammatory disorder with a genetic basis, characterized by oral and genital ulcers, uveitis, pustular erythematous cutaneous lesions, arthritis, central nervous system involvement and possible vascular manifestations such as venous thrombosis, arteritis and aneurysms. To investigate the association and actual differentiation between these two entities in a large-scale population-based study. Data for this study was collected from the databases of "Clalit Health Services", the largest state-mandated health service organization in Israel. All adult members diagnosed with BD were included (n=892) and as well as their age- and sex-matched controls (n=4444), creating a cross-sectional population-based study. Medical records of all subjects were analyzed for documented FMF. A logistic regression model was done to estimate how BD, age, gender, BMI, ethnicity and socioeconomic status contributed as risk factors for FMF. The proportion of FMF in patients with BD increased compared with those reported in controls (5.83% and 0.23%, respectively, P30. Our data imply that understating the differentiation between FMF and BD is not evident and clear in a real-life population of patients with BD.

Canine lymphoma (CL) is one of the most common forms of spontaneous canine neoplasia. Improved understanding of the genetic and environmental factors associated with CL may provide benefits for the study of non-Hodgkin's and Hodgkin's lymphoma in humans. Uveodermatologic lymphoma is reported in a single household of Portuguese water dog, and the etiology is discussed. A 1-year-old female intact Portuguese water dog was referred to the Ophthalmology Service of the Veterinary Teaching Hospital of the Autonomous University of Barcelona because of acute blepharospasm of the right eye in association with a multinodular dermatosis. Physical and ophthalmological examination and a complete diagnostic work-up, including skin and ocular histopathology and immunohistochemistry, were performed. Three months prior, in Galicia (Spain), 1200 km away from Barcelona, a male dog of the same litter showed very similar oculodermatological clinical signs and skin histopathology, and immunohistochemistry were obtained. The clinical diagnoses were anterior exudative uveitis, iridal masses, and secondary glaucoma. Histopathology and immunohistochemistry revealed a nonepitheliotropic lymphoma rich in B cell in dog 1 and rich in T cell in dog 2. It is proposed that an underlying genetic predisposition could have played a role in the development of lymphoma in these two young related dogs. © 2012 American College of Veterinary Ophthalmologists.

ERYTHEMA ELEVATUM DIUTINUM AS MOST PROBABLE DIAGNOSIS: A CASE REPORT

Full Text Available Cutaneous vasculitis can be cause by multiple disorders or can be idiopathic. Many diseases can present with similar findings, therefore histopathologic examination is always require for confirming the right diagnosis. The erythema elevatum diutinum (EED is a localized vasculitis, classified as a neutrophilic dermatosis. It’s a rare cutaneous condition, distribute on the extensor surface of the extremities, more frequently in the dorsum of the hands, knees and elbows. They have a symmetric distribution and can be asymptomatic, painful; or pruritic, sometimes accompanied paresthesias. The most common clinical presentation is round erythematous papules which become erythemato-violaceous or purpuric plaques. There are not pathognomonic histopathological findings, but can present as a leukocytoclastic vasculitis with perivascular neutrophilic infiltration in the middle and superficial dermis. I presented the case of a 61-year-old female, with erythematous purpuric painful plaques, irregular, symmetric and elevated, located in both thenar regions of her hands and paresthesias. The patient’s presentation is consistent with multiple characteristics of EED such as the description of the lesions, the anatomical location, the symmetric distribution and the histopathological findings of an initial disease. This patient does not have all the clinical progression and outcome, due to the initial stage of the disease.

Full Text Available Gougerot-Carteaud syndrome (GCS is a rarely seen dermatosis characterized by reticular and pigmented plaques with a tendency to merge with each other in areas such as the neck, upper body, and axilla in young adults. A 20-year-old male patient presented to the dermatology outpatient clinic with the complaints of itching and brown patches affecting the trunk, back and the neck. He had no endocrine diseases and used no drugs. Dermatological examination revealed reticulated, hyperpigmented, verrucous papules and plaques on the anterior surface of his trunk, upper back, and neck region. No fungal elements were encountered in the potassium hydroxide examination. Histopathologically, basket-like hyperkeratosis, papillomatosis, mild acanthosis, and hyperpigmentation in the basal layer were detected. Minocycline treatment was initiated at a dose of 100 mg/daily. At the three-month follow-up visit, minocycline treatment was terminated due to lack of clinical response, and 30 mg/day acitretin treatment was initiated. The lesions showed marked improvement except for a slight hyperpigmentation in the first month of the treatment. We report here a case of GCS in which acitretin was started due to clinical unresponsiveness to minocycline treatment and, substantially, a favorable result was obtained in a short time.

Full Text Available Lichen sclerosus et atrophicus (LSA is a chronic inflammatory dermatosis that results in white plaques with epidermal atrophy usually affecting the genital area in both adults and children. The causes of LSA are not clear but possible predisponsing factors include trauma, infection (borrelia, human papilloma virus, autoimmune diseases and local irritation. This study is a retrospective case review of children and adults with LSA attending the department of Dermatology at the Royal Infirmary in Edinburgh, clinical notes for 22 patients were reviewed for age, sex, personal and familial history, symptoms associated diseases and clinical course and treatment. The mean ages at diagnosis of LSA in 9 children (8F: 1M and 13 adults (13 F were 7 and 57.5 years respectively. The mean duration of illness was 1.5 year in children and 5.5 year in adults. Itching was the most common symptom in both children and adults. Children also suffered with difficulties in defaecation and in micturation , dribbling, incontinence, constipation and bleeding. Atopy and hypothyroidism were common associated conditions in both the groups. Squamous cell carcinoma of the vulva was confirmed in two adult patients. This study showed the variable symptoms in children, which seemed more severe than in the adult population.

Full Text Available Sweet’s syndrome is a neutrophilic dermatosis characterized by an abrupt onset of painful erythematous lesions showing neutrophilic infiltrates in the dermis. Fever and an elevated neutrophil level are generally observed. Sweet’s syndrome may be idiopathic, malignancy-associated, or drug-induced (mainly involving granulocyte colony-stimulating factor (G-CSF administration. Although systemic corticosteroids are usually effective, the symptoms of Sweet’s syndrome recur in some refractory cases. Herein, we report a case of a 55-year-old Japanese woman with recurrent symptoms of fever (>39°C and painful erythematous lesions on her four extremities, trunk, and neck. Laboratory findings revealed leukocytosis and high levels of C-reactive protein (CRP and G-CSF. She was diagnosed with a recurrence of Sweet’s syndrome, and was exclusively treated with granulocyte and monocyte adsorption apheresis (GMA therapy once a week for 3 consecutive weeks. After the first session of GMA therapy, all symptoms including the erythematous lesions and fever were completely resolved, and serum G-CSF level was reduced. Leukocyte count, neutrophil count, serum amyloid A protein, and CRP levels were restored within normal ranges by 2 weeks. Thus, GMA therapy can successfully treat a patient with recurrent Sweet’s syndrome, potentially related to the restoration of elevated serum G-CSF levels.

Full Text Available Pityriasis rubra pilaris (PRP is an exceptionally rare, chronic inflammatory dermatosis of unknown etiology. Patients classically present with small, follicular keratosis and salmon-colored plaques that begin at the head and neck and slowly progress to widespread erythroderma including the palms and soles. It is difficult to distinguish PRP from other inflammatory dermatoses; however, features that help aid in the diagnosis include ‘islands' of spared skin, orangish hue and typical findings on biopsy. There are no specific guidelines on therapy and treatment options include corticosteroids, vitamin D analogs, retinoids, methotrexate, cyclosporine, azathioprine and tumor necrosis factor alpha antagonists. Unfortunately options are limited for patients when these drugs do not work. We report a case of chronic PRP, refractory to conventional treatment, successfully treated with ustekinumab monotherapy. The patient was treated with 90 mg subcutaneous ustekinumab injections and began to show improvement within only 8 weeks. Long-term control of the disease has been attained without any significant side effects. We report this case to show that ustekinumab can be used as an alternative treatment method for patients with chronic, unremitting PRP. Treatment response is remarkably rapid and the infrequent dosing leads to patient compliance and a significantly improved quality of life.

Full Text Available Context: Candida species are opportunistic yeasts that cause infections ranging from simple dermatosis to potentially life-threatening fungemia. The emergence of resistance to antifungal drugs has been increased in the past two decades. Aim: the present study we determined to find out the susceptibility profiles of clinical isolates of Candida species against four antifungal drugs, including amphotericin B, ketoconazole, fluconazole and itraconazole. Materials and Methods: Antifungal susceptibility testing of the yeasts was done in accordance with the proposed guidelines for antifungal disk diffusion susceptibility testing of yeasts based on the CLSI document M44-A. Results: A total of 206 yeast isolates were assessed. Among the evaluated Candida species, the highest rates of resistance to ketoconazole were seen in Candida glabrata (16.6% and Candida albicans (3.2%. Susceptibility and intermediate response to fluconazole were seen in 96.6% and 3.4% of the Candida isolates, respectively. A total of 19 (9.2% yeast isolates showed petite phenomenon including 11 C. glabrata, 3 C. albicans, 2 Candida dubliniensis and one isolate of each Candida krusei and Candida parapsilosis. Conclusion: The high number of petite mutation in the isolated yeasts should be seriously considered since it may be one of the reasons of antifungal treatment failure.

Transverse nasal groove is a condition of cosmetic concern which awaits due recognition and has been widely described as a shallow groove that extends transversely over the dorsum of nose. However, we observed variations in the clinical presentations of this entity, hitherto undescribed in literature. We conducted a clinicoepidemiological study of transverse nasal lesions in patients attending our outpatient department. We conducted a prospective observational study. We screened all patients attending our out-patient department for presence of transverse nasal lesions, signs of any dermatosis and associated other skin conditions. One hundred patients were recruited in the study. Females (80%) predominated over males. Most patients were of 15-45 years age group (70%). Majority of the transverse nasal lesions were classical transverse nasal groove (39%) and others included transverse nasal line (28%), strip (28%), ridge (4%) and loop (1%). Seborrhoeic diathesis was the most common condition associated with transverse nasal lesion. Occurrence of transverse nasal line, strip, ridge and loop, in addition to classical transverse nasal groove implies that latter is actually a subset of transverse nasal lesions. Common association of this entity with seborrheic dermatitis, seborrhea and dandruff raises a possibility of whether transverse nasal lesion is a manifestation of seborrheic diathesis.

Dynamic concept of oral lichen planus. The diagnosis easy at early stages may become difficult in ancient lichen planus. Lichen planus is a chronic inflammatory dermatosis of the skin, skin appendages and mucous membranes, which frequently affects the oral mucosa. Its aetiology still remains unknown, and currently accepted pathogenesis is that of an autoimmune cell-mediated disease. To the contrary of skin lichen planus, oral lichen planus is a long-term chronic disease with dynamic evolution, in which progressive and profound changes of the clinical and histopathological aspects occur over time and under the influence of various exogenous factors. By convention, in the history of the oral lichen planus four successive stages can be distinguished without well-defined boundaries between them. These stages can be defined as an initial phase; a long intermediate phase with alternating periods of activity and quiescence, which has a gradually increasing risk of malignant transformation; a late stage which activity is traditionally diminished; and a post-lichen cicatricial stage with an absent or negligible and undetectable activity, often undiagnosed because clinically unrecognized; in this stage, the lesion does not respond to usual treatments, but retains the same risk of malignant transformation.

Icotinib hydrochloride, a novel inhibitor of epidermal growth factor receptor tyrosine kinase, has been approved by the State Food and Drug Administration for the treatment of advanced non-small-cell lung cancer. Up to date, cutaneous response to icotinib is largely unknown. Here we report an uncommon lesional phenomenon in a 56-year-old Chinese male with non-small-cell lung cancer, who received icotinib as a second-line treatment. Characteristic papulopustular rash on the chest and back was observed 4 days later. Interestingly, the rash completely spares a pre-irradiated area. The immunohistochemical study in the lesional skin area and spared skin area revealed a significant decrease in CD1a + Langerhans cells, Ki-67 as well as FGFR2 in the spared area than in the lesional area. Thus, the present case indicated that loss of the basal layer of proliferative cells and antigen-presenting cells (Langerhans cell), as well as the down-regulation of FGFR2 signaling in the pre-irradiated skin area, may join forces in inhibiting icotinib-associated cutaneous reactions. To our knowledge, this is the first report of both lesional area and lesion-spared area in a Chinese male receiving treatment with a new epidermal growth factor receptor-tyrosine kinase inhibitor (icotinib). The immunohistochemical reactions described here also provide new insight into the pathogenesis of epidermal growth factor receptor-tyrosine kinase inhibitor-related skin toxicities, and the role that other tyrosine kinase receptors (including FGFR) played in non-small-cell lung cancer.

Se caracteriza por cinco rasgos principales: 1 aparición brusca de placas eritemato-dolorosas en cara, cuello y extremidades; 2 fiebre; 3 leucocitosis polimorfonuclear; 4 denso infiltrado dérmico a predominio neutrofilico; 5 rápida respuesta al tratamiento esteroideo. Se puede clasificar en cinco grupos: idiopático, parainflamatorio, paraneoplásico, secundario a drogas y asociado a embarazo. En el 20% de los casos se asocia a enfermedades malignas, representando las hematológicas el 85% y los tumores sólidos el 15% restante. Se presenta una serie de siete casos de síndrome de Sweet asociado a neoplasias, diagnosticados durante el período 2002-2006, de los cuales seis correspondieron a enfermedades oncohematológicas y el restante a tumores sólidos. Como comentario de dicha casuística, se hace hincapié en la importancia del diagnóstico de este síndrome, debido a que puede anunciar la recaída del tumor o la progresión de la enfermedad de base. De esta manera, mediante el uso de métodos de diagnóstico y tratamiento oportunos, se lograría mejorar la calida de vida de estos pacientes.

However, there are few objective surveys that demonstrate and prove a direct relationship between alcohol and a specific dermatosis. OBJECTIVES: to verify the prevalence of dermatoses in alcoholics, analize the dermatological changes found in these patients and their evolution during alcoholic abstinence. Also, to compare the results obtained with a non-alcoholic control group and with the data found in medical literature. METHODS: the dermatologic conditions of 278 alcoholic patients (250 men, 28 women were studied over a period of 4 years, and compared to those of a control group of 271 non-alcoholic individuals (249 men, 22 women, members of the Military Police Force. The individuals in both groups were between 20 and 60 years old. RESULTS: Pellagra, nummular eczema, purpura pigmentosa chronica (also known as pigmented purpuric dermatosis and psoriasis were more frequent in the group of alcoholics and, apparently, occurred in parallel with alcoholism that seems to play a role in the evolution of these dermatoses. The dermatopathies were more frequent before the age of forty, regardless of factors such as profession, race or gender. CONCLUSION: the association of dermatoses and alcoholism was extremely significant according to the statistical data. Alcoholism can be considered a risk factor for pellagra, psoriasis, nummular eczema and purpura pigmentosa chronica dermatoses, which can, as well, be considered alcoholism indicators. FUNDAMENTOS: A relação direta entre o alcoolismo e as dermatoses vem sendo avaliada em recentes pesquisas. No entanto são poucos os estudos objetivos que demonstram e comprovam uma relação direta entre o álcool e uma determinada dermatose. OBJETIVOS: Verificar a prevalência de dermatoses em alcoolistas, avaliar as alterações dermatológicas encontradas nesses doentes e sua evolução frente abstin

Full Text Available Autoimmune bullous skin diseases (ABDs are uncommon, potentially fatal diseases of skin and mucous membranes which are associated with deposits of autoantibodies and complement against distinct molecules of the epidermis and dermal/epidermal basement membrane zone (BMZ. These autoantibodies lead to a loss in skin molecular integrity, which manifests clinically as formation of blisters or erosions. In pemphigus vulgaris, loss of adhesion occurs within the epidermis. The pioneering work of Ernst H. Beutner, Ph.D. and Robert E. Jordon, M.D. confirmed the autoimmune nature of these diseases. Walter F. Lever, M.D. contributed significantly to our understanding of the histopathologic features of these diseases. Walter Lever, M.D. and Ken Hashimoto, M.D. contributed electron microscopic studies of these diseases, especially in pemphigus vulgaris and bullous pemphigoid. In bullous pemphigoid (BP, linear IgA bullous dermatosis, epidermolysis bullosa acquisita (EBA and dermatitis herpetiformis (DH, loss of adhesion takes place within or underneath the BMZ. Classic EBA demonstrates extensive skin fragility; DH is commonly associated with gluten-sensitive enteropathy, and manifests clinically with pruritic papulovesicles on the extensor surfaces of the extremities and the lumbosacral area. The clinical spectrum of bullous pemphigoid includes tense blisters, urticarial plaques, and prurigo-like eczematous lesions. Pemphigoid gestationis mostly occurs during the last trimester of pregnancy, and mucous membrane pemphigoid primarily involves the oral mucosa and conjunctivae and leads to scarring. Linear IgA bullous dermatosis manifests with tense blisters in a „cluster of jewels”-like pattern in childhood (chronic bullous disease of childhood and is more clinically heterogeneous in adulthood. Many of the autoantigens in these disorders are known and have been well characterized. ABDs may be influenced by both genetic and exogenous factors. The diagnoses of

The present study was carried out to investigate the epidemiology and lesions of avian pox in captive peafowl chicks. Overall values of morbidity, mortality and case fatality were 45.2%, 27.1% and 60.0%, respectively. The chicks of 9 to 12 weeks of age showed a significantly (P<0.001) higher prevalence rate than other age groups. The morbidity and mortality due to avian pox in peafowl chicks was significantly (P<0.001) reduced when kept in mosquito-proof cages and hatched under broody chicken hens. Morbidity due to poxvirus infection on the peafowl farm was 82%, 26% and 12% in successive years. This reduction might have been the result of the introduction of mosquito-proof nets after year 1, although this was not the subject of a controlled experiment. All of the peafowl chicks suffering from dry pox showed pustular and nodular lesions on eye lids, beak, legs and toes. Distribution of lesions in different body parts varied significantly (P<0.023). Lesion diameters were less than 1 cm (59.73%), 1 to 2 cm (23.75%) and more than 2 cm (16.87%). Histopathological studies revealed extensive proliferation of subdermal connective tissue and infiltration of heterophils and macrophages. The keratinocytes showed degenerative changes in the form of cytoplasmic vacuolation, ballooning and hyper-chromatic nuclei. Eosinophilic intracytoplasmic inclusions (Bollinger bodies) in keratinocytes were consistently present. It was concluded that avian pox rendered high morbidity, mortality and case fatality in peafowl chicks.

BACKGROUND Acne is a common disease in adolescents, but there are no epidemiological data for acne in Brazil. OBJECTIVES To estimate the prevalence and degree of acne in adolescents from Sao Paulo and study socio-demographic factors, family history and lifestyle, associated with the disease. METHODS Cross-sectional study with 452 adolescents aged between 10 and 17 (mean=13.3 years), students from elementary and high school, examined by 3 independent evaluators. RESULTS 62.4% were female, 85.8% white and 6.4% were aged 14. The prevalence was 96.0% and increased with age - all students over 14 had acne. The most prevalent form of acne was comedonal (61.1%), followed by mild (30.6%) and moderate (7.6%) papular-pustular, which affected mostly the face (97.5%). About half of the adolescents reported family history for acne in mother or father, and 20.6% reported previous treatment for acne. There was a higher chance of presenting non-comedonal acne with increased age (pacne in adolescents varies widely due to the clinical features and diagnostic methods used. Adolescents whose brothers/sisters had acne (OR=1.7-p=0.027) and those over 13 (OR=8.3-pacne. CONCLUSION This study showed high prevalence of acne in adolescents from Sao Paulo, predominantly the comedonal form on the face, with a higher chance of presenting non-comedonal acne with increased age.

Direct immunofluorescence assay (DFA) is commonly used for the rapid identification of herpes simplex virus (HSV) infection in mucocutaneous lesions, yet little is known about its diagnostic accuracy. To determine the diagnostic yield and accuracy of HSV DFA for the diagnosis of mucocutaneous HSV infection in pediatric patients. Retrospective cross-sectional study of all patients who underwent HSV DFA testing by the Texas Children's Hospital Diagnostic Virology between January 1, 1995 and December 31, 2005. HSV DFA sensitivity, specificity, positive likelihood ratio (LRs), and negative LRs were estimated using viral culture as the reference standard. 659 specimens were submitted for HSV DFA with concurrent viral cultures. Viral cultures were positive for HSV type 1 in 158 (24%) and HSV type 2 in 2 (0.3%). There were 433 different patients with a median age of 8.6 years. Types of lesions were as follows: 50% ulcerative, 26% vesicular, 8% erythema or purpura, 5% pustular, and 11% missing. Of the 659 specimens submitted for HSV DFA, 160 (24%) were inconclusive due to inadequate cells. Of the 499 adequate specimens, overall HSV DFA test accuracy was: sensitivity 61%, specificity 99%, LR positive 40, and LR negative 0.39. A quarter of specimens submitted for HSV DFA testing are not adequate for DFA testing. When HSV DFA can be performed, it is specific, but not sensitive, for the identification of mucocutaneous HSV infection in children. Copyright (c) 2010 Elsevier B.V. All rights reserved.

To observe the clinicopathologic and resistance profiles of the Nocardia brasiliensis causing cutaneous nocardiosis in Taiwan, 12 N. brasiliensis isolates were prospectively collected from patients with cutaneous nocardiosis in a hospital during 2002-2012. Clinicopathologic data were obtained, and isolates were identified by biochemical methods and 16S rRNA sequencing. Susceptibilities to 14 antimicrobial compounds were tested. Isolates were further genotyped by sequencing of 16S rRNA, secA1, hsp65, and gyrB genes. The nodulopustular pyoderma associated with sporotrichoid spreading was the most common skin presentations caused by N. brasiliensis. All of the isolates were susceptible to amikacin, gentamicin, tobramycin, piperacillin/tazobactam, and trimethoprim/sulfamethoxazole and resistant to kanamycin, erythromycin, and oxacillin, while susceptibilities to imipenem, vancomycin, penicillin-G, tetracycline, clindamycin, and ciprofloxacin varied among the 12 isolates. GyrB genotyping delineated the 12 isolates into 2 major groups, which was coincident with different single nucleotide substitutions at position 160 (G versus T) of 16S rRNA, different levels of imipenem minimum inhibition concentration (4-32 versus 0.25-0.75 mg/L), and prevalence of lymphadenitis (66.7 versus 16.7%). We have noted that tiny pustular lesions can be the first sign of cutaneous nocardiosis, which we believe has not been previously emphasized. No resistance to trimethoprim and sulfamethoxazole was found; therefore, sulphonamide drugs remain effective for treatment of cutaneous nocardiosis in Taiwan. Copyright © 2013 Elsevier Inc.

Full Text Available Acitretin, a synthetic retinoid and the active metabolite of etretinate has been increasingly used over the past two decades. It has proved effective in the treatment of many conditions associated with hyperkeratosis and dyskeratosis. A Google scholar search for the use of acitretin in pediatric dermatoses was done using the words “pediatric dermatoses,” “acitretin,” “etretinate,” “systemic retinoids,” “psoriasis,” “pityriasis rubra pilaris,” “ichthyoses,” “disorders of keratinization,” “Darier's disease,” “palmoplantar keratoderma,” “verrucae,” “lichen planus,” “lupus erythematosus,” and “lichen sclerosus.” All the articles were retrieved and classified into review articles, studies, double-blinded trials, and case reports. The final data were then analyzed and presented in a narrative fashion. It has been found that acitretin is useful in a number of pediatric dermatoses. It is preferred over other drugs in pustular psoriasis. Good results can be obtained in various disorders of keratinization, and it may even prove life-saving in conditions like harlequin ichthyosis. However, long-term maintenance therapy is required and exacerbations are known on discontinuing the drug. It can also be used as alternative therapy for many other pediatric dermatoses where the primary treatment has failed. Acitretin should be used even in children for the proper indications. However, proper clinical and laboratory surveillance has to be maintained in patients on long-term acitretin.

A 2-year-old male fennec fox presented with a 4 month history of nonpruritic, crusty skin lesions on the forehead, the pinnae and the tail tip. Initial investigations, including routine haematology, biochemistry profile, multiple skin scrapings, trichoscopic examination, Wood's lamp examination and fungal culture, failed to reveal any abnormalities. Histopathological examination of a first set of skin biopsies showed an interface dermatitis pattern, with lymphocyte infiltration in the basal layer, a significant lymphocytic exocytosis and occasional apoptotic basal epidermal keratinocytes; periodic acid Schiff stain did not reveal any fungal elements. On further biopsies, there was a pustular neutrophilic dermatitis, with numerous crusts containing high numbers of arthrospores and fungal hyphae. Trichophyton mentagrophytes infection was confirmed on fungal culture and PCR. The fennec fox received oral itraconazole (5 mg/kg once daily for 6 weeks) combined with a miconazole and chlorhexidine shampoo applied on affected areas once weekly, followed with an enilconazole dip. The fox improved dramatically, and a fungal culture performed at 6 weeks was negative. Unfortunately, a few days later the fennec fox developed anorexia, icterus and died. To the authors' knowledge, this is the first report of Trichophyton infection in a fennec fox and, although a postmortem examination was not performed, this is possibly the first report of fatal acute liver failure associated with itraconazole in a canid. © 2012 The Authors.

Improving outcomes in patients with psoriasis.

Tidman, Michael J

2013-01-01

Psoriasis is a heterogeneous inflammatory disorder that targets the skin and joints. It affects 1.3-2% of the population. The diagnosis of plaque psoriasis is usually straightforward, a helpful diagnostic clue is the tendency for silver scales to appear after gentle scratching of a lesion. Stress, streptococcal infection and drugs including beta-blockers, antimalarials and lithium may precipitate or exacerbate psoriasis. Psoriasis, especially when severe, predisposes to metabolic syndrome, and patients with psoriasis are at increased risk of ischaemic heart disease, hypertension, stroke, type 2 diabetes and hyperlipidaemia. Additionally, psoriasis sufferers appear at increased risk of uveitis, inflammatory boweldisease, lymphoma, non-melanoma skin cancer, COPD and venous thromboembolism. Psoriasis should be assessed on the basis of: severity, impact on physical, psychological and social wellbeing, symptoms of arthritis and the presence of comorbidities. Poor response to topical therapy may be as much to do with lack of compliance as with lack of efficacy. The number of treatments each day should be kept to a minimum, and patients should be reviewed after four weeks when initiating or changing topical therapy to improve adherence to treatment and assess response. The majority of patients with psoriasis can be managed in primary care, although specialist care may be necessary at some point in up to 60% of cases. Patients with erythrodermic or generalised pustular psoriasis should be referred for a same day dermatological opinion, and if psoriatic arthritis is suspected, early referral for a rheumatological opinion is recommended.

Management of psoriasis in adolescence

Full Text Available Christina Fotiadou, Elizabeth Lazaridou, Demetrios Ioannides First Department of Dermatology–Venereology, Aristotle University Medical School, Thessaloniki, Greece Abstract: Psoriasis is a chronic inflammatory cutaneous disorder affecting 2%–4% of the world's population. The prevalence of the disease in childhood and adolescence ranges between 0.5% and 2%. The management of psoriasis in adolescence is an intriguing and complicated task. Given the paucity of officially approved therapies, the very limited evidence-based data from randomized controlled trials, and the absence of standardized guidelines, physicians must rely on published experience from case reports both from the field of dermatology as well as from the application of these drugs for other pediatric conditions coming from the disciplines of rheumatology, gastroenterology, and oncology. Psoriatic adolescents deal with a potentially disfiguring and lifelong disease that could permanently impair their psychological development. It must be clarified to them that psoriasis does not have a permanent cure, and therefore the main goal of treatments is to establish disease control and prolonged periods between flares. The majority of adolescents suffer from mild psoriasis, and thus they are treated basically with topical treatment modalities. Phototherapy is reserved for adolescents with mild-to-moderate plaque disease and/or guttate psoriasis when routine visits to specialized centers do not create practical problems. Systemic agents and biologics are administered to patients with moderate-to-severe plaque psoriasis, pustular psoriasis, or erythrodermic psoriasis.

Full Text Available Objective: This study was aimed to define the clinical and demographic findings of psoriasis in childhood. Methods: In this retrospective study, the data from 64 children with psoriasis admitted at the our dermatology clinic between January 2007 and January 2011 were included whose data were fully. Results: Of the patients, 37 (57.8% were boys and 27 (42.2% were girls. Mean age of the children was 10.08 ±3.98 years (3-16. In 10 (15% cases, a positive family history was detected. The most frequent localizations at onset were trunk (46.9%, scalp (28.1%, knee-elbow (10.9% and extremities (7.9%, respectively. The most commonly seen clinical types were plaque (68.8%, guttate (20.3%, palmoplantar (9.4%, pustular (1.6%, respectively. Nine children had nail involvement. Out of all patients, 21.9% had upper respiratory tract infections and 9.4% had emotional stres. Four cases were diagnosed with depression. Of the cases, two cases were on non-steroid anti-inflammatory medication, and 4 of them were on antibiotics. Systemic treatments were given to 21.9% of the cases besides topical treatments. Conclusion: The epidemiological studies of psoriasis during childhood period for different countries have been reported. In this study, the ratio shows differences when compared to those previous studies. There are few epidemiologic studies for Turkey. We believe that further epidemiological studies including large number of patients' groups will contribute the diagnosis and treatment of the disease.

Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome is a newly characterized autoinflammatory disorder, caused by mutations in PSMB8. It is characterized by early-onset fevers, accompanied by a widespread, violaceous and often annular, cutaneous eruption. While the exact pathogenesis of this syndrome is still obscure, it is postulated that the inflammatory disease manifestations stem from excess secretion of interferons. Based on preliminary blood cytokine and gene expression studies, the signature seems to come mostly from type I interferons, which are proposed to lead to the recruitment of immature myeloid cells into the dermis and subcutis. In this study, we systematically analyzed skin biopsies from 6 CANDLE syndrome patients by routine histopathology and immunohistochemistry methods. Skin lesions showed the presence of extensive mixed dermal and subcutaneous inflammatory infiltrate, composed of mononuclear cells, atypical myeloid cells, neutrophils, eosinophils and some mature lymphocytes. Positive LEDER and myeloperoxidase staining supported the presence of myeloid cells. Positive CD68/PMG1 and CD163 staining confirmed the existence of histiocytes and monocytic macrophages in the inflammatory infiltrate. CD123 staining was positive, demonstrating the presence of plasmacytoid dendritic cells. Uncovering the unique histopathologic and immunohistochemical features of CANDLE syndrome provides tools for rapid and specific diagnosis of this disorder as well as further insight into the pathogenesis of this severe, life-threatening condition.

The identification of natural products exerting a combined effect with therapeutic agents could be an alternative for cancer treatment, reducing the concentration of the drugs and side effects. Geopropolis (Geo) is produced by some stingless bees from a mixture of vegetable resins, gland secretions of the bees and soil. It has been used popularly as an antiseptic agent and to treat respiratory diseases and dermatosis. To determine whether Geo enhances the anticancer effect of carboplatin, methotrexate and doxorubicin (DOX), human laryngeal epidermoid carcinoma (HEp-2) cells were treated with Geo alone or in combination with each drug. Cell growth, cytotoxicity and apoptosis were evaluated using 3-(4,5-dimethyl thiazol-2yl)-2,5-diphenyltetrazolium bromide (MTT) assay, lactate dehydrogenase (LDH) release, and flow cytometry. Scratch assay was used to analyze cell migration and transmission electron microscopy to observe morphologic alterations. The influence of Geo on drug resistance was also investigated assessing P-glycoprotein (P-gp) action. Geo inhibited cell proliferation and migration. The combination Geo+DOX led to the highest cytotoxic activity and induced apoptosis, leading to loss of membrane integrity. Geo had no effect on P-gp-mediated efflux of DOX. Data indicate that Geo combined with DOX could be a potential clinical chemotherapeutic approach for laryngeal cancer treatment. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Full Text Available Background: Erythema annulare centrifugum (EAC is an inflammatory dermatosis with unknown etiology. It is usually self-limited, but chronic disease may be difficult to treat. We observed incidentally the therapeutic effect of erythromycin for EAC among patients taking erythromycin for other diseases. Aim: To evaluate the treatment response of erythromycin for EAC. Materials and Methods: During the study period, from July 2007 to February 2011, all patients with EAC were assigned to erythromycin stearate tablet 1000 mg per day for two weeks. EAC was diagnosed by a constellation of clinical and pathological findings. The efficacy (before and after the treatment was assessed clinically by one dermatologist and photographically by two blinded dermatologists. Secondary outcomes included adverse drug effects and recurrence. Results: Eight patients were enrolled in this study. Most patients had chronic relapsing disease with poor response to previous treatment. All the patients showed rapid response with profound reduction in the size of lesion and erythema two weeks after initiation of erythromycin treatment. The response was so obvious and complete that a coincidental response was less likely. Three patients had recurrence of disease and they tended to have more extensive lesions. Readministration of erythromycin was effective. All patients tolerated the treatment well. Conclusion: Our study documented erythromycin as a safe and cost-effective treatment for EAC.

Through the story of two families presenting ichthyosis, we report the support and social integration difficulties inherent in these genetic diseases. Family No. 1: a 38-year-old shepherd and his wife of 25 years both had lamellar ichthyosis that had been present continually since childhood. They had had 2 stillborn infants as well as a live newborn that were all presenting lamellar ichthyosis. Family No. 2: a 45-year-old housewife was seen at our consultation with her 3 youngest children aged 8 years, 6 years and 18 months. According to the mother, at birth, all 3 children were covered with a membrane resembling plastic that crackled during movement, and they had red eyes. Examination of the 3 children revealed a clinical picture of lamellar ichthyosis with ectropion, malformed ears and brachydactyly. Although they presented delayed growth and weight development, psychomotor development was normal. There was no consanguinity between the parents. In both families, the visible nature of the dermatosis resulted in discrimination and ostracism. The precarious living conditions of the parents and the high cost of treatment in an African setting resulted in degradation of quality of life with exacerbation of the difficulties of social integration, resulting in a lack of schooling and a bleak future for these children.

On average, vitiligo affects one percent of the world population. More than 75% of the patients have negative self-image on account of the disease. The emotional impact of the dermatosis is frequently neglected by the caretaker, which has negative influence on therapy and prognosis. OBJECTIVE; To check the effect of vitiligo on patients emotions and discuss the mind-body interaction and its impact on the disease. METHODS; In their first medical visit, one hundred patients with various forms of vitiligo answered a question about which emotions were elicited by the presence of the spots. RESULTS; Eighty-eight percent of the patients with spots in exposed areas complained of unpleasant emotions versus twenty-seven percent of those with spots in unexposed areas. The most frequently referred emotions were fear, specifically of expansion of the spots (71%), shame (57%), insecurity (55%), sadness (55%) and inhibition (53%). CONCLUSION; Chronic illnesses generate in human beings a negative experience propitiated by the expectation of suffering. Besides appropriate scientific guidance, vitiligo patients need emotional comfort. Treatment outcomes and patients compliance to it, and even their resilience to face occasional therapeutic failures, rely on good physician-patient relationship. At a time when doctors make use of reputable therapeutic resources, it is indispensable that dermatologists become able to evaluate the patient in an integrative fashion.

Full Text Available This paper describes the case of a one-year-old female American Pit Bull Terrier, presented with the history of progressive baldness. The initial clinical signs were demonstrated by symmetric, primarily non-pruritic alopecia that began in the perineal, genital, and ventral abdominal regions and propagated cranially to the thorax and to the neck. Based on physical and dermatological examination, laboratory findings, and results of skin biopsy, a hormone-responsive dermatosis was diagnosed. Once hypothyroidism and hyperadrenocorticism were ruled out, with the help of hormonal tests, the diagnosis was specified as alopecia X. The first treatment option recommended for the patient and subsequently completed was ovariohysterectomy. After three months, the owner reported improvement; the dog was almost covered with hair. The patient was presented again six months later, showing almost the same dermatological symptoms, which, however, were of a more striking character than before ovariohysterectomy. Again a series of hormonal tests was carried out. Considering the elevated basal and post-adrenocorticothropin stimulation progesterone concentrations, the final aetiology of the disease was determined as an adrenal sex hormone imbalance. Therefore trilostan therapy was initiated. The trilostan dosage of 8 mg/kg/day was divided and given 2 times daily. This treatment led to complete hair regrowth in the dog within four months. No adverse effects associated with trilostane were recognized.

Primary biliary cholangitis (PBC) is a rare autoimmune cholestatic liver disease. It is often associated with extrahepatic autoimmune diseases. Skin disorders are sporadically reported in association with PBC. We report an unusual case of PBC associated with acquired reactive perforating dermatosis (ARPD) and present a review of the literature on skin disorders associated with PBC. Our patient presented to the dermatology department with generalized pruritus associated with nodular perforating skin lesions on the trunk, and cholestatic liver disease of unknown origin. After having established both diagnosis of ARPD and PBC, she was managed in an interdisciplinary manner, and both her skin and liver conditions improved gradually. Only one similar case is reported in the literature, in that case, the liver disease was not treated. By reviewing the literature, we found that lichen planus, vitiligo, and psoriasis are the most frequent skin disorders associated with PBC. However, there is only limited data about specific skin disorders associated with PBC. This case report of a patient with PBC associated with ARPD underlines the importance of interdisciplinary management of patients with rare liver diseases combined with rare skin disorders. The present review of the literature shows that probably, immune-mediated skin conditions are not more frequent in PBC patients than in the general population. However, the available data are scant; there is a need for high-quality data on skin conditions associated with PBC.

The diagnosis of post-kala-azar dermal leishmaniasis (PKDL), a dermatosis that provides the only known reservoir for the parasite Leishmania donovani in India, remains a problem. Timely recognition and treatment of PKDL would contribute significantly to the control of kala-azar. We evaluated here the potential of the enzyme-linked immunosorbent assay (ELISA) as a diagnostic tool for PKDL. Antigen prepared from promastigotes and axenic amastigotes with parasite isolates that were derived from skin lesions of a PKDL patient gave sensitivities of 86.36 and 92%, respectively, in the 88 PKDL cases examined. The specificity of the ELISA test was examined by testing groups of patients with other skin disorders (leprosy and vitiligo) or coendemic infections (malaria and tuberculosis), as well as healthy controls from areas where this disease is endemic or is not endemic. A false-positive reaction was obtained in 14 of 144 (9.8%) of the controls with the promastigote antigen and in 14 of 145 (9.7%) of the controls with the amastigote antigen. Evaluation of the serodiagnostic potential of recombinant k39 by ELISA revealed a higher sensitivity (94.5%) and specificity (93.7%) compared to the other two antigens used. The data demonstrate that ELISA with crude or recombinant antigen k39 provides a relatively simple and less-invasive test for the reliable diagnosis of PKDL. PMID:11874880

An increase of international trips has been taken place in recent years, being Spain one of the principal issuing countries of internationl tourism. Dermatological diseases returning from tropical areas are frequent causes of medical consultation. Etiology is varied. OBJECTIVE. The aims of the present study are: to evaluate the importance of dermatological pathology in patients who come to a consultation of Tropical Medicine; to analyze the influence of duration, motive and the destination of the trip; and to describe the most frequent entities. An observational prospective study was realized, including all Spanish people older than 18 years-old who came to a consultation of Tropical Medicine. The period of study was between January 1st, 2004 and December 31st, 2007. Epidemiological and clinical items were collected from the group of patients with dermatological pathology. There were attended 3,351 new consultations, with 660 cases of skin diseases. The infectious pathology constituted an almost the half (48.5%) of the dermatological pathology (320 cases). The injuries more frequently described were associated with stings arthropods (113 cases) and cutaneous larva migrans (CLM) (84), mycoses (52) and urticaria (43). The appearance of dermatosis in the travelers seems to be determined by the motive, the duration and the destination. Given the heterogeneity of the pathology, the recognition of the injuries is fundamental to initiate the suitable treatment.

Lichen planus is an inflammatory dermatosis with a prevalence of approximately 1%. Recent meta-analyses show that patients with hepatitis C virus have a 2.5- to 4.5-fold increased risk of developing lichen planus. Lichen planus has also followed vaccinations and has specifically been attributed to the hepatitis B vaccine, the influenza vaccine, and the tetanus-diphtheria-acellular pertussis vaccine. We describe a case of lichen planus in a hepatitis C virus-infected African American male occurring in temporal association with the administration of the tetanus-diphtheria-acellular pertussis vaccine. The patient's presentation was clinically consistent with lichen planus and confirmed by biopsy. It is likely that many cases of vaccine-induced lichen planus have gone unpublished or unrecognized. In areas with high prevalence of hepatitis C virus infection, we may expect to see more cases of vaccine-induced lichen planus especially in light of the updated Centers for Disease Control and Prevention tetanus-diphtheria-acellular pertussis vaccination recommendations. This case serves to educate healthcare providers about vaccine-induced lichen planus and, in particular, the need to counsel hepatitis C virus-infected patients about a potential risk of developing lichen planus following vaccination. We also reflect on current theories suggesting the T-cell-mediated pathogenesis of lichen planus and the role that hepatitis C virus and toxoid or protein vaccines may play in initiating the disease.

Deficiency of interleukin-1 receptor antagonist (DIRA) is a rare life-threatening autoinflammatory disease caused by autosomal recessive mutations in IL1RN. DIRA presents clinically with early onset generalized pustulosis, multifocal osteomyelitis, and elevation of acute phase reactants. We evaluated and treated an antibiotic-unresponsive patient with presumed DIRA with recombinant IL-1Ra (anakinra). The patient developed anaphylaxis to anakinra and was subsequently desensitized. Genetic analysis of IL1RN was undertaken and treatment with anakinra was initiated. A 5-month-old Indian girl born to healthy non-consanguineous parents presented at the third week of life with irritability, sterile multifocal osteomyelitis including ribs and clavicles, a mild pustular rash, and elevated acute phase reactants. SNP array of the patient's genomic DNA revealed a previously unrecognized homozygous deletion of approximately 22.5 Kb. PCR and Sanger sequencing of the borders of the deleted area allowed identification of the breakpoints of the deletion, thus confirming a homozygous 22,216 bp deletion that spans the first four exons of IL1RN. Due to a clinical suspicion of DIRA, anakinra was initiated which resulted in an anaphylactic reaction that triggered desensitization with subsequent marked and sustained clinical and laboratory improvement. We report a novel DIRA-causing homozygous deletion affecting IL1RN in an Indian patient. The mutation likely is a founder mutation; the design of breakpoint-specific primers will enable genetic screening in Indian patients suspected of DIRA. The patient developed anaphylaxis to anakinra, was desensitized, and is in clinical remission on continued treatment.

Full Text Available Introduction. Acne vulgaris is a common, chronic skin disease that shows a characteristic clinical picture. Skin lesions occur primarily in the seborrheic areas of the body, i.e., the face, back, and chest. Mandelic acid yields very good results when used to treat excessive actinic keratosis (keratosis actinica, hyperpigmentation (lentigo solaris and melasma, and meshlike wrinkles, which are primarily caused by sun-induced aging of the skin. This therapy is well suited for the care of skin with acne vulgaris. Objective. To evaluate the efficacy of dermo-cosmetics containing 5% or 10% mandelic acid for the skin care of patients with acne vulgaris. Material and methods. An open study was carried out on 60 patients with papulo-pustular acne, who applied dermocosmetics to their skin for 2 months. Patients were divided into two subgroups of 30 patients each. One group was tested with a 5% mandelic acid containing cosmetic while the other group was tested with a 10% mandelic acid containing cosmetic. After the treatment was completed, acne severity was evaluated according to the Hellgren-Vincent scale. Results. Physical examinations performed during the study revealed a gradual improvement in the condition of the skin in both groups, with a reduction in the number of pustules, inflammatory nodules, and comedones. The proportion of patients in each group showing a reduction in disease severity according to the Hellgren-Vincent scale was similar. Conclusions. The results of the present study show that products containing 5% or 10% mandelic acid are both safe and effective for the treatment of acne.

Haemophilus ducreyi, the etiologic agent of the sexually transmitted genital ulcer disease chancroid, has been shown to associate with dermal collagen fibers within infected skin lesions. Here we describe NcaA, a previously uncharacterized outer membrane protein that is important for H. ducreyi collagen binding and host colonization. An H. ducreyi strain lacking the ncaA gene was impaired in adherence to type I collagen but not fibronectin (plasma or cellular form) or heparin. The mutation had no effect on serum resistance or binding to HaCaT keratinocytes or human foreskin fibroblasts in vitro. Escherichia coli expressing H. ducreyi NcaA bound to type I collagen, demonstrating that NcaA is sufficient to confer collagen attachment. The importance of NcaA in H. ducreyi pathogenesis was assessed using both swine and human experimental models of chancroid. In the swine model, 20% of lesions from sites inoculated with the ncaA mutant were culture positive for H. ducreyi 7 days after inoculation, compared to 73% of wild-type-inoculated sites. The average number of CFU recovered from mutant-inoculated lesions was also significantly reduced compared to that recovered from wild-type-inoculated sites at both 2 and 7 days after inoculation. In the human challenge model, 8 of 30 sites inoculated with wild-type H. ducreyi progressed to the pustular stage, compared to 0 of 30 sites inoculated with the ncaA mutant. Together these results demonstrate that the collagen binding protein NcaA is required for H. ducreyi infection.

Full Text Available Etiology, transmission and protection: Neisseria gonorrhoeae (the gonococcus is the etiological agent for the strictly human sexually transmitted disease gonorrhea. Infections lead to limited immunity, therefore individuals can become repeatedly infected. Pathology/symptomatology: Gonorrhea is generally a non-complicated mucosal infection with a pustular discharge. More severe sequellae include salpingitis and pelvic inflammatory disease which may lead to sterility and/or ectopic pregnancy. Occasionally, the organism can disseminate as a bloodstream infection. Epidemiology, incidence and prevalence: Gonorrhea is a global disease infecting approximately 60 million people annually. In the United States there are approximately 300, 000 cases each year, with an incidence of approximately 100 cases per 100,000 population. Treatment and curability: Gonorrhea is susceptible to an array of antibiotics. Antibiotic resistance is becoming a major problem and there are fears that the gonococcus will become the next “superbug” as the antibiotic arsenal diminishes. Currently, third generation extended-spectrum cephalosporins are being prescribed. Molecular mechanisms of infection: Gonococci elaborate numerous strategies to thwart the immune system. The organism engages in extensive phase (on/off switching and antigenic variation of several surface antigens. The organism expresses IgA protease which cleaves mucosal antibody. The organism can become serum resistant due to its ability to sialylate lipooligosaccharide in conjunction with its ability to subvert complement activation. The gonococcus can survive within neutrophils as well as in several other lymphocytic cells. The organism manipulates the immune response such that no immune memory is generated which leads to a lack of protective immunity.

Stigmatization is the assignment of negative perceptions to an individual because of a perceived difference from the population at large. Skin conditions are frequently the reason of social rejection with a consequent negative influence on the personal and social life of patients. The aim of the current study was to review the available instruments that can be successfully utilized to measure the stigmatization level among dermatological patients. We performed our search on PubMed up to November 2016 and utilized combinations of key phrases containing such words as stigmatization, skin, dermatology, names of various skin conditions (psoriasis, vitiligo, acne, etc.), measurement. The search found a considerable number of articles - 548. After filtering them through a precise selection process, 58 articles remained. We concentrated only on the methodological aspects to assess stigmatization in various dermatoses. The review ascertained that there exist numerous instruments in the form of questionnaires. They were utilized in various researches in order to assess the stigmatization level in patients with skin problems. We divided them into two main groups: dermatology specific instruments (6 questionnaires) and dermatosis/disease specific ones (8 questionnaires). It is recommended to use dermatology-specific instruments to compare the stigmatization level in various skin conditions. They can be utilized as well as a first line tools to study the feeling of stigmatization in specific skin diseases; however, where it is possible, they should be supplemented with the disease-specific instrument for deeper analysis of both qualities of life and stigmatization.

Full Text Available Introduction: By considering an increase in drug resistance against red mites, finding the nonchemical herbal acaricide against Dermanyssus gallinae (De Geer (Acari: Mesostigmata is necessary to kill them and to reduce the chemical resistance against chemical acaricides in this specie. Dermanyssus gallinae is a potential vector of the causal agent of several viral diseases such as Equine encephalitis and St. Louis encephalitis. It can be a vector of bacteria such as Salmonella spp., Mycobacterium spp. and Erysipelothrix rhusiopathiae. It is also known to cause itching dermatosis in humans. In this study acaricidal and repellent activities of essential oil of Eucalyptus globulus against Dermanyssus gallinae were studied. Methods: After extracting the essential oil, different concentrations of the plant extract were prepared. Then, acaricidal effect of different concentrations was tested on poultry red mite, Dermanyssus gallinae, by dropping 3-4 drops of essential oil on mites. Repellent activity of essential oil was tested by Y-tube olfactometer bioassay. After the test, total number of killed and repellent mites reported. Results: Concentration of 1:2 or 50% had more acaricidal effect on mites. Also essential oil of Eucalyptus globulus had repellent activity against red mites. Conclusion: This study showed that essential oil of Eucalyptus globulus had acaricidal and repellent activities against red mites. Hence it might be used as a herbal acaricide against it to kill and to reduce the chemical resistance in this specie.

Full Text Available Background and Design: Pediatric dermatology is characterized by skin disorders which have frequencies different from those in adults. Skin biopsies are necessary for differential diagnosis and clinicopathologic correlation is very important. The aim of this study was to evaluate retrospectively the pediatric dermatology cases in whom biopsy was performed for differential diagnosis and to investigate the contribution of biopsy to diagnosis of skin disorders. Material and Methods: The cases from whom biopsy was taken in the pediatric dermatology clinic during a three-year period were evaluated retrospectively for pre-diagnoses, biopsy diagnoses, and success of biopsies.Results: Two hundred thirteen (1.7% skin biopsies had been taken from a total of 12420 patients. Henoch-Schönlein purpura, psoriasis, pityriasis lichenoides, pityriasis rosea, lichen planus, pityriasis rubra pilaris, erythema multiforme, atopic dermatitis, granuloma annulare, and pigmented purpuric dermatosis were the most frequent skin disorders diagnosed dermatopathologically. In a total of 120 (56.3% cases, the biopsy diagnosis was within the pre-diagnosis and a biopsy consistency was present. In 25 (11.7% cases, biopsy had no contribution to the differential diagnosis. An absolutely different diagnosis which was incompatible with the pre-diagnosis had been reported in 10 (4.6% cases. Conclusion: In pediatric dermatology, skin biopsy is very helpful for the differential diagnosis. An easy biopsy procedure for the patient, an effective designation of biopsy indication, a good dermatopathologic correlation and an experienced team of pediatric dermatopathology increase the success of skin biopsies.

The immuno-pathological conversions of canine demodicosis.

Singh, Shanker K; Dimri, Umesh

2014-06-16

Canine demodicosis is a common but exigent noncontagious parasitic dermatosis caused by overpopulation of the host-specific follicular mites of various Demodex species. Receptivity of dogs to demodicosis and progression of the clinical disease are influenced by numerous factors including; genetic defect, alteration of skin's structure and biochemistry, immunological disorders, hormonal status, breed, age, nutritional status, oxidative stress, length of hair coat, stage of oestrus cycle, parturition, endoparasitism and debilitating diseases. Of these, the immune status is thought to be the most significant. Thus, in the present review we intended to edify the immuno-pathological conversions of canine demodicosis. Generalized demodicosis requires a cutaneous environment that is ecologically and immunologically favorable for extreme colonization of demodectic mites. Demodex canis mites can down regulate the CD4+ T cells; possibly by an increased rate of apoptosis or immunological exhaustion of CD4+ T cells. An increased apoptosis of peripheral leukocytes confers progression of the clinical manifestations. Mites induced elevation of TGF-β and inhibition of TNF-α mRNA expression might be a key factor for revealing the difference in the mechanism of onset between localized and generalized demodicosis. Moreover, an elevated serum level of IL-10 could be accountable for the recurrence as well as occurrence of demodicosis in dogs. Over production of reactive oxygen species can corroborate immunological discrepancies in dogs with demodicosis. Copyright © 2014 Elsevier B.V. All rights reserved.

Clinical Evaluation of a New-Formula Shampoo for Scalp Seborrheic Dermatitis Containing Extract of Rosa centifolia Petals and Epigallocatechin Gallate: A Randomized, Double-Blind, Controlled Study.

Scalp seborrheic dermatitis is a chronic type of inflammatory dermatosis that is associated with sebum secretion and proliferation of Malassezia species. Ketoconazole or zinc-pyrithione shampoos are common treatments for scalp seborrheic dermatitis. However, shampoos comprising different compounds are required to provide patients with a wider range of treatment options. This study was designed to evaluate a new-formula shampoo that contains natural ingredients-including extract of Rosa centifolia petals and epigallocatechin gallate (EGCG)-that exert antioxidative, anti-inflammatory, and sebum secretion inhibitory effects, and antifungal agents for the treatment of scalp seborrheic dermatitis. Seventy-five patients were randomized into three treatment groups; new-formula shampoo, 2% ketoconazole shampoo, and 1% zinc- pyrithione shampoo. The clinical severity scores and sebum levels were assessed by the same dermatologists at baseline (week 0), and at 2 and 4 weeks after using the shampoo. User satisfaction and irritation were also assessed with the aid of a questionnaire. The efficacy of the new-formula shampoo was comparable to that of both the 1% zinc-pyrithione shampoo and the 2% ketoconazole shampoo. Furthermore, it was found to provide a more rapid response than the 1% zinc-pyrithione shampoo for mild erythema lesions and was associated with greater user satisfaction compared with the 2% ketoconazole shampoo. However, the new-formula shampoo did not exhibit the previously reported sebum inhibitory effect. Extract of R. centifolia petals or EGCG could be useful ingredients in the treatment of scalp seborrheic dermatitis.

Over recent decades, both the incidence and prevalence of chronic inflammatory bowel disease have continued to rise in industrialized countries; the disease is frequently associated with extracutaneous involvement and comorbidity. The purpose of this work was to investigate the frequency and specificity of mucocutaneous manifestations in Crohn's disease (CD) and ulcerative colitis (UC). An extensive search in peer-reviewed journals via PubMed was performed; presented is a summary and analysis of various studies and data, including data of patients treated at our department. CD and UC are frequently associated with mucocutaneous symptoms; however, primary/specific disease-associations are exclusively seen in CD patients. These include peri-anal and -stomal fistulas and ulcerations, "metastatic" Crohn's disease as well as oral granulomatous disease. Moreover, in both CD and UC, there occur several other inflammatory skin conditions such as erythema nodosum, pyoderma gangrenosum, hidradenitis suppurativa, chronic oral aphthous disease, Sweet syndrome, pyostomatitis vegetans, and bowel-associated dermatosis-arthritis syndrome. Malnutrition syndromes (zinc and vitamin deficiencies) are only rarely observed. On skin and oral/genital mucous membranes various different inflammatory manifestations may be observed during the course of CD or UC. However, most data about a direct pathogenic relationship of the gastrointestinal and dermatologic disorders are quite heterogeneous or even contradictory. Nevertheless, knowledge of these conditions and their possible association with CD and UC could be crucial for early diagnosis and initiation of an appropriate therapy and thus be essential to prevent secondary tissue damage.

Acne is one of the dermatological pathologies with the highest incidence around the world. It is a multifactorial disease and its treatment can be complex. Propionibacterium acnes play a key role in the inflammation of this dermatosis. Topical antibiotics, including mainly erythromycin and clindamycin, have been used, but there is controversy over their use due to the widely documented bacterial resistance. For this reason a meta-analysis of the publications over the past 10 years is presented in order to confirm this hypothesis. A search was made of the publications over the past 10 years that included the results of antibiogams of patients with acne. MeSH type searches were performed with the terms "acne vulgaris", "Propionibacterium acnes", "topical administration", "treatment", "erythromycin", "clindamycin", "nadifloxacin", "antibacterial agent", "bacterial drug resistance" in PubMed, Ovid, EBSCO, Cochrane, ScienceDirect and ClinicalKey meta-searches. A total of 13 articles were found that met the inclusion criteria. The mean odds ratio (OR 1.24, 95% CI) of the articles showed a slight tendency toward resistance of Propionibacterium acnes. An increase in bacterial resistance to topical erythromycin and clindamycin can be confirmed, thus the use of these antibiotics is recommended in selective cases for short periods, and in combination with benzoyl peroxide for the best clinical outcome in patients with acne vulgaris.

Full Text Available Background: Acanthosis nigricans (AN is a dermatosis characterized by thickened, hyperpigmented plaques, typically on the intertriginous surfaces and neck. Common in some populations, its prevalence depends on race. Clinicians should recognize AN; it heralds disorders ranging from endocrinologic disturbances to malignancy. In this review, we discuss the pathogenesis of AN and its clinical implications and management. Materials and Methods: We selected 30 patients for the study. Diagnosis of associated disorders was established by history, physical examination, body mass index (BMI, hormone measurements by radioimmunoassays of thyroidnfunction tests, free testosterone, 17 (OH progesterone, dehydroepiandrosterone sulfate (DHEAS, cortisol, gonadotropins, prolactin, immunoreactive insulin, and C-peptide levels. Results and Discussion: In our study, the flexural involvement (flexures of groins, knees and elbows was seen in 40% patients, lip involvement was seen in 6.6% patients, and dorsal involvement was seen in 3.3% patients each.

Smallpox holds a unique position in the history of medicine. It was the first disease for which a vaccine was developed and remains the only human disease eradicated by vaccination. Although there have been claims of smallpox in Egypt, India, and China dating back millennia [1-4], the timescale of emergence of the causative agent, variola virus (VARV), and how it evolved in the context of increasingly widespread immunization, have proven controversial [4-9]. In particular, some molecular-clock-based studies have suggested that key events in VARV evolution only occurred during the last two centuries [4-6] and hence in apparent conflict with anecdotal historical reports, although it is difficult to distinguish smallpox from other pustular rashes by description alone. To address these issues, we captured, sequenced, and reconstructed a draft genome of an ancient strain of VARV, sampled from a Lithuanian child mummy dating between 1643 and 1665 and close to the time of several documented European epidemics [1, 2, 10]. When compared to vaccinia virus, this archival strain contained the same pattern of gene degradation as 20 th century VARVs, indicating that such loss of gene function had occurred before ca. 1650. Strikingly, the mummy sequence fell basal to all currently sequenced strains of VARV on phylogenetic trees. Molecular-clock analyses revealed a strong clock-like structure and that the timescale of smallpox evolution is more recent than often supposed, with the diversification of major viral lineages only occurring within the 18 th and 19 th centuries, concomitant with the development of modern vaccination.

Although studies regarding prevalence of metabolic syndrome (MS) in Asian psoriatic patients are limited and show varying results, a previous report describes a significant increase in prevalence of MS in Thai psoriatic patients, as compared with rates in the general population. However, no significant association between MS and psoriasis severity using the Psoriasis Area and Severity Index (PASI) was found, which differs from the findings of Korean and Japanese studies. This study aimed at re-evaluating the association between MS and psoriasis severity in Thai patients using current assessment (PASI) and chronological assessment (historical course and interventions). A total of 273 psoriatic patients were recruited. After controlling for age and sex, 96 patients were assigned to the MS group and 96 patients to the non-MS group. Similar to the previous study, no significant differences were identified between metabolic and non-metabolic patients regarding PASI, age of onset, disease duration and family history of psoriasis. However, the numbers of hospitalizations (P = 0.018) and interventions (P = 0.028) were significantly higher in metabolic patients than in non-metabolic patients. Further, a greater number of metabolic components was significantly associated with a higher number of hospitalizations (P = 0.012), pustular or erythrodermic psoriasis episodes (P = 0.049), and interventions (P = 0.005). Body mass index of 23 kg/m 2 or more, abdominal obesity and high blood pressure were associated with an increased risk of treatment failure. Using chronological assessment, our study supported that MS negatively affects psoriasis severity and treatment outcomes. Screening for MS is highly recommended for psoriatic patients. © 2016 Japanese Dermatological Association.

Exploring ancient microbial community assemblages by creating complex lipid biomarker profiles for stromatolites and microbial mats in Hamelin Pool, Shark Bay, Australia

Stromatolites that are biogenic in origin, a characteristic that can be determined by the coexistence of microbial mats (active microbial communities) and stromatolites (lithified structures) like in Hamelin Pool, comprise one of the best modern analogs to ancient microbial community assemblages. Comprehensive lipid biomarker profiles that include lipids of varying persistence in the rock record can help determine how previously living microbial communities are represented in lithified stromatolites. To create these profiles, the samples analyzed included non-lithified smooth, pustular, and colloform microbial mats, as well as smooth and colloform stromatolites. Select samples were separated into upper and lower layers of 5cm depth each. Intact polar lipids, glycerol dialkyl glycerol tetraethers, and bacteriohopanepolyols were analyzed via liquid chromatography-mass spectrometry (LC-MS) coupled to a Quadropole Time-of-Flight (QTOF) mass spectrometer; additionally, fatty acids from each sample were analyzed using gas chromatography-mass spectrometry (GC-MS) to prove consistent signatures with those determined by Allen et al. in 2010 for similar microbial mat samples. In accordance with those findings, 2-methylhopanoids were detected, as well as limited signals from higher (vascular) plants, the latter of which suggests terrestrial inputs, potentially from runoff. The rarely detected presence of 3-methylhopanoids appears in a significant portion of the samples, though further isolations of the molecule are needed to confirm. While all lipid profiles were relatively similar, certain differences in relative composition are likely attributable to morphological differences of the mats, some of which allow deeper oxygen and/or sunlight penetration, which influence the microbial community. However, overall similarities of transient and persistent lipids suggest that the microbial communities of both the non-lithified microbial mats and stromatolites are similar.

Topical infections, involving a number of diseases such as impetigo, eczema, pustular acne, psoriasis and infected seborrheic dermatitis are one among the many challenges to health which stand out for their profound impact on human species. The treatment of topical infections has always been a difficult proposition because of the lack of efficacy of existing anti-infectives, longer period of treatment and yet incomplete recovery. The increasing emergence of antibiotic resistant bacterial strains like Staphylococcus aureus, Methicillin-Resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa undermine the need of development of new delivery systems to enhance the therapeutic efficacy of existing topical anti-infectives. The application of nanotechnology to medicine, or nanomedicine, is rapidly becoming a major driving force behind ongoing changes in the anti-infective field because of its interaction at the sub-atomic level with the skin tissue. The latter, in the current scenario, points towards vesicular carriers like liposomes, lipidic nanoparticles and silver nanoparticles etc. as the most promising drug delivery solutions for topical infection disorders. These have exhibited immense significance owing to their uniqueness to facilitate the interactions at interfaces with the barrier membranes. The present review summarizes the emerging efforts in combating topical infections particularly using nanomedicine based delivery systems as new tools to tackle the current challenges in treating infectious diseases. Besides, compiling various research reports, this article also includes formulation considerations, mechanisms of penetration and patents reported. Despite the new emerging technologies and delivery systems, efforts are still needed in the right direction to combat this global challenge.

Linear IgA bullous disease (LABD) is an autoimmune skin disease characterized by subepidermal blisters and IgA autoantibodies directed against the epidermal basement membrane zone (BMZ) of the skin. Various antigens have been identified as targets of IgA autoantibodies including BP180, a type II glycoprotein that spans the BMZ and lamina lucida. Previously, we have identified a subset of LABD patients whose sera contained IgA antibodies against the 16th noncollagenous (NC16A) domain of BP180. NC16A was previously shown to harbor epitopes that are recognized by both autoantibodies and T cells from patients with bullous pemphigoid and herpes gestationis and is thought to be associated with the development of these immunobullous diseases. The aim of this study was to determine whether T lymphocytes from LABD patients with anti-NC16A IgA autoantibodies respond to epitopes in the same region of the BP180 protein. Indeed, of the four LABD patients in our study, all had T cells that specifically proliferated in response to NC16A. Moreover, two subfragments of NC16A were identified as the predominant targets of LABD T cells. Further analysis of T cell lines and clones derived from these patients revealed that these cells express a CD4 memory T cell phenotype and secrete a Th1/Th2 mixed-cytokine profile, characteristics similar to those of T cells in bullous pemphigoid patients. Our data suggest that the BP180 protein, typically the NC16A region, is the common target of both cellular and humoral immune responses in some LABD patients. This information helps to further elucidate the autoimmune mechanisms in this disease.

Irritant contact dermatitis and allergic contact dermatitis (ACD) are frequent among agricultural workers and require targeted interventions. Patch testing is necessary for differential diagnosis, but patch testing with pesticides is uncommon. This study explores the frequency of ACD and sensitization to pesticides among highly exposed banana plantation workers. Frequently and recently used pesticides on banana plantations in Divala, Panama, were documented. A pesticide patch test tray specific for this population was prepared. A structured interview was administered to 366 participants, followed by a complete skin examination. The pesticide patch test series, as well as a standard patch test series, was applied to 37 workers with dermatoses likely to be pesticide related and to 23 control workers without dermatoses. The pesticide patch tests identified 15 cases (41%) of ACD (20 positive reactions) among the 37 workers diagnosed with pesticide dermatosis. Three controls had allergic reactions to pesticides (4 positive reactions). The pesticides were carbaryl (5 cases), benomyl (4 cases), ethoprophos (3), chlorothalonil (2), imazalil (2), glyphosate (2), thiabendazole (2), chlorpyrifos (1), oxyfluorfen (1), propiconazole (1), and tridemorph (1). Ethoprophos and tridemorph had not been previously identified as sensitizers. Thus, the prevalence of ACD was 0.03 (15 of 366). On the basis of observed prevalences of positive patch-test reactions among the subgroups with and without dermatoses, we estimated that > or = 16% of the entire population may be sensitized to pesticides. Sensitization to pesticides among banana plantation workers is a frequent occupational health problem. Pesticide patch test trays should be used in assessing skin diseases in highly exposed workers.

Full Text Available Mutations in the CD40 ligand (CD40L gene (CD40LG lead to X-linked hyper-IgM syndrome (X-HIGM, which is a primary immunodeficiency (PID characterized by decreased serum levels of IgG and IgA and normal or elevated IgM levels. Although most X-HIGM patients become symptomatic during the first or second year of life, during which they exhibit recurrent infections, some patients exhibit mild phenotypes, which are usually associated with hypomorphic mutations that do not abrogate protein expression or function. Here, we describe a 28-year-old man who initially presented with recurrent infections since the age of 7 years, when he exhibited meningitis caused by Cryptococcus neoformans. The patient had no family history of immunodeficiency, and based on clinical and laboratory presentation, he was initially diagnosed with common variable immunodeficiency (CVID. In subsequent years, he displayed several sporadic episodes of infection, including pneumonia, pharyngotonsillitis, acute otitis media, rhinosinusitis, fungal dermatosis, and intestinal helminthiasis. The evaluation of CD40L expression on the surface of activated CD3+CD4+ T cells from the patient showed decreased expression of CD40L. Genetic analysis revealed a novel de novo mutation consisting of a 6-nucleotide insertion in exon 1 of CD40LG, which confirmed the diagnosis of X-HIGM. In this report, we describe a novel mutation in the CD40L gene and highlight the complexities of PID diagnosis in light of atypical phenotypes and hypomorphic mutations as well as the importance of the differential diagnosis of PIDs.

Full Text Available Introduction:The etiology of seborrheic dermatitis is not fully understood. It has been observed that a number of anascogenic yeasts of Malassezia spp. is related to the intensity of the symptoms. The aim of the study is to measure the concentration of selected inflammatory factors IL-2, IL-4, IFN-γ and TNF-α in the serum by an immunoenzymatic method, as well as to confirm the relationship between the studied factors and the clinical condition of the patients (sex, the intensity of skin lesions according to the Scaparro scale and, finally, to compare the results with the control group.Material/Methods:The total number of subjects who participated in the study was 66. The control group (C consisted of 30 volunteers (23 females and 7 males, with no clinical disorders, aged 24–65 (37.41±6.08 years. Thirty-six patients with seborrheic dermatitis (16 females and 20 males, aged 19–76 (38.61±13.77, made up the study group. The determination of IL-2, IL-4, IFN-γ and TNF-α was performed by ELISA using a Human High Sensitivity kit (Diaclone, France. Clinically, the intensity of the disease process was evaluated on the Scaparro et al. scale, as modified by Kaszuba.Results:We observed statistically significantly higher levels of IL-2 and IFN-γ in patients with seborrheic dermatitis compared to the control group.Conclusions:We conclude that seborrheic dermatitis is a dermatosis characterized by a cell type immune response with an important role of IFN-γ and IL-2. 

Influence of treatments on prognosis for vulvar lichen sclerosus: facts and controversies.

Lichen sclerosus (LS) is an inflammatory dermatosis with a predilection for the anogential skin. Vulvar LS can be a debilitating disease, causing pruritus and pain, and it carries the potential for atrophy, scarring, and significant functional impairment. Recently, many advances have been made regarding the etiology and natural history of the disease process; however, much debate still exists regarding the most advantageous medical and surgical management of this disorder. In an effort to provide a comprehensive review on current vulvar LS literature, the following three controversies will be discussed: (1) optimal disease treatment, (2) theories behind LS's oncogenicity and treatments for minimizing malignancy, and (3) the value of surgical treatment for LS. Ultra-potent topical corticosteroids (TCSs) are the first-line treatment for vulvar LS, while topical calcineurin inhibitors (TCIs) remain second-line agents for patients for whom TCS treatment resulted in incomplete resolution of symptoms or adverse events. Due to the relapsing nature of the disease, long-term maintenance therapy is often required. In addition, recent advances have contributed to the understanding of the association between LS and squamous cell carcinoma (SCC). While the exact mechanism responsible for LS-associated SCC is not known, immune dysregulation and inflammation may play an important role; therefore, successful treatment of LS should be directed towards alleviation of symptoms and reversal of the underlying histopathologic changes. Patients with LS-associated malignancy, as well as patients who need correction of functionally restrictive, scarring processes, can successfully undergo surgical intervention with tissue conservation. © 2013 Elsevier Inc.

Full Text Available The objective of this study was to determine the frequency of ectoparasites in urban domiciled dogs treated at nine private veterinary clinics in the city of Lavras, Minas Gerais, Brazil. Visible and palpable ectoparasites specimens were collected manually from 67 dogs during the period of September 2004 to May 2005, kept in flasks with ethanol 70º GL and identified under a stereomicroscope. In the case of mites that cause mange, performed the analysis of the results obtained from 155 skin scrapings of the same number of dogs with clinical suspicion of parasitic dermatosis was performed, and sent to diagnostic at the Laboratory of Parasitic Diseases of Federal University of Lavras (UFLA, during the period of September 2002 to July 2007. A total of 540 ectoparasites were recorded, and four species were identified: Rhipicephalus sanguineus (60%, Ctenocephalides canis and C. felis (both 36%, and Dermatobia hominis larvae (4%. In scraped skin, positive results were verified in 12.9% (20/155, of which 80.0% with Demodex canis (16/20 and 20.0% with Sarcoptes scabiei var. canis (4/20. After ectoparasites identification a database with the dogs´medical records was made and analyzed by SPSS 12.0. It can be concluded that the predominant species of ectoparasites in dogs treated at private veterinary clinics in the city of Lavras, MG, were Ctenocephalides canis and C. felis (Siphonaptera: Pulicidae and R. sanguineus (Acari: Ixodidae and Demodex canis (Acari: Demodecidae that had a significant predominance (p<0.05 on scraped skin of young animals with suspicion of canine demodicosis.

Full Text Available Cutaneous anthrax has a mortality rate of 20% if no antibacterial treatment is applied. The clinical manifestations of cutaneous anthrax are obviously striking, but coinfection may produce atypical lesions and mask the clinical manifestations and proper laboratory diagnosis. Anthrax is known to be more common in the Middle East and Iran is one of the countries in which the zoonotic form of anthrax may still be encountered. We report a case of a 19-years-old male who used to apply Venetian ceruse on his skin. Venetian ceruse (also known as Spirits of Saturn is an old cosmetic product used for skin whitening traditionally made from sheep’s spinal cord. The patient referred to the Referral Laboratory, Mazandaran University of Medical Sciences, Sari, Iran, with atypical dermatosis, pronounced pain, and oedema of the affected tissue. It was confirmed by both conventional and molecular analysis that culture was a mixture of Bacillus anthracis and Trichophyton interdigitale. The patient was initially treated with ceftriaxone (1000 mg/day for two weeks, gentamicin (1.5–2 mg/kg/day, terbinafine (200 mg/week for one month, and 1% clotrimazole cream (5 weeks two times per day which resulted in gradual improvement. No relapse could be detected after one-year follow-up. Anthrax infection might present a broader spectrum of symptoms than expected by clinicians. These unfamiliar characteristics may lead to delayed diagnosis, inadequate treatment, and higher mortality rate. Clinicians need to be aware of this issue in order to have successful management over this infection.

Postadolescent acne is usually described as an inflammatory, mild-to-moderate dermatosis, frequently involving the lower third of the face, the jawline, and the neck. However, we have also frequently observed a clinical form predominantly characterized by retention lesions (microcomedones and macrocomedones), with few inflammatory lesions (comedonal postadolescent acne [CPAA]), which appears significantly correlated with cigarette smoking. We sought to investigate the clinical features of postadolescent acne in a group of female patients affected by acne and its relationship with cigarette smoking. A total of 226 women with acne (25-50 years) attending our department were examined by a team of 3 dermatologists, to assess the age of onset of the disease, and the number, type, and distribution of acne lesions. In all, 192 of 226 patients (85.0%) were classified as having CPAA and 34 as having papulopustular postadolescent acne. A smoking habit was confirmed in 150 of 226 (66.3%). Remarkably, 72.9% of patients with CPAA were smokers as compared with only 29.4% of those with papulopustular postadolescent acne (P < .0001). Possible limitations are related to geographic area or to the prevalence of darker skin types (III and IV) (data about skin types have not been collected). Other possible aggravating factors (ie, stress and diet) have not been investigated. According to our results, CPAA appears as the most frequent clinical form of postadolescent acne and seems to be strictly correlated with cigarette smoking.

Full Text Available Alopecia areata (also known as spot baldness is a disease with multifactorial aetiology, including genetic, hormonal, autoimmune and  psychological factors as well as nervous system disorders. This disorder belongs to  the group of dermatological conditions modified by psychological factors. Clinical experience indicates that stress and psychological aspects contribute significantly to the onset and/or exacerbation of alopecia areata. Pharmacological treatment of this dermatosis is often ineffective or insufficient. Therefore, a holistic approach to the disease, including both medical and  psychological aspects, is  crucial. It  is  emphasised in  the subject literature that some forms of  psychotherapy and pharmacotherapy used in patients with alopecia areata improve their psychophysical condition, and, consequently, stimulate the regrowth of their hair. Research has shown that cognitive-behavioural therapy complements dermatological treatment of alopecia areata, improving the quality of life of patients. The aim of cognitive and behavioural techniques is, on the one hand, to change the maladaptive negative convictions about oneself, the world, and the disease, and, on the other hand, to acquire the ability to cope with negative emotional states and difficult situations, such as a disease. The aim of the paper is to present the results of a literature review on the efficiency of pharmacotherapy and the role of cognitive-behavioural therapy in alopecia areata.

Full Text Available Background: Pyoderma ga ngrenosum (PG is a rare, inflammatory, destructive neutrophilic dermatosis, which mimics other ulcerative conditions. Materials and Methods: In a retrospective study based on patients diagnosed with PG over a 3-year period (2010-2013, we evaluated demographics, anatomical sites, number of lesions, subtypes, histopathology, associated conditions, treatment regimens, healing time, and recurrence. Results: Of our five patients, there were three males and two females, age ranging between 19 and 58 years (mean age 38 years. Four had single lesions localized to the lower limbs while one had multiple lesions (more than five over bilateral hands and legs. Ulcerative subtype was observed in all the patients. One exhibited pathergy. Skin biopsies were done in four patients, revealing dense neutrophilic infiltrates in three cases and leukocytoclastic vasculitis in one. Associated systemic diseases were observed in all patients, four having inflammatory bowel disease and one having both systemic lupus erythematosus and anti-phospholipid syndrome. The patients were all treated with systemic corticosteroids either alone or in combination with immunosuppressants (e.g., azathioprine, mycophenolate mofetil, tacrolimus, and wound dressing. Split-thickness skin graft was done in one patient. Complete healing was achieved in all patients, ranging from one to 3 months after diagnosis. No recurrence was reported. Conclusions: Systemic corticosteroids, either alone or in combination with steroid-sparing agents are the mainstay of treatment. Should family physicians encounter a rapidly progressing ulcer that has poor response to usual wound management, timely referral to dermatology should be made.

Incontinentia pigmenti is a genodermatosis described by Garrod and in 1920 by Bloch, Sulzberger, Siemens y Bardach. It is an ectodermic disorder that affects skin, teeth, eyes and may also have neurological problems. The IP2 name describes the histological characteristics, the incontinence of melanin into the melanocytes cells in the epidermal basal layer and its presence in superficial dermis. IP2 is an x-linked dominant condition but genetic heterogeneity may exist. The patient was 4 yrs 5 months old when she came for the first time. In a physical exploration she presented sparse and thin hair, eyelashes and eyebrows, beaked nose, labial protrusion, the four central teeth have a conic crown and there was also a delayed eruption of other teeth, right eye strabismus, hipoacusia, language defects and a trunk, legs, feet, and face dermatosis characterized by grouped vesicles, hyperkeratotic and warty lesions and brownish-gray lesions in a lineal pattern. The patient s father had hypopigmented lesions in the posterior regions of both legs. The oral clinical and radiographic exams showed diverse anomalies. Both the patient's and the father's chromosomal studies were normal. In the present case we can see that the father has IP2 without supernumeraries X, with the antecedent that his mother had something similar. It is possible that the inheritance was autosomic dominant or it is a different mutation of NEMO (NF-kappa-B essential modulator) gene to a classical one, which was found in some affected men. It is necessary to carry out a molecular study of these patients.

Pyoderma gangrenosum (PG) is an uncommon dermatosis with a limited evidence base for treatment. We sought to estimate the effectiveness of topical therapies in the treatment of patients with PG. This was a prospective cohort study of UK secondary care patients with a clinical diagnosis of PG that was suitable for topical treatment (recruited between July 2009 and June 2012). Participants received topical therapy after normal clinical practice (primarily topical corticosteroids [classes I-III] and tacrolimus 0.03% or 0.1%). The primary outcome was speed of healing at 6 weeks. Secondary outcomes included the following: proportion healed by 6 months; time to healing; global assessment; inflammation; pain; quality of life; treatment failure; and recurrence. Sixty-six patients (22-85 years of age) were enrolled. Clobetasol propionate 0.05% was the most commonly prescribed therapy. Overall, 28 of 66 (43.8%) ulcers healed by 6 months. The median time to healing was 145 days (95% confidence interval, 96 days to ∞). Initial ulcer size was a significant predictor of time to healing (hazard ratio, 0.94 [95% confidence interval, 0.88-1.00); P = .043). Four patients (15%) had a recurrence. Our study did not include a randomized comparator. Topical therapy is potentially an effective first-line treatment for PG that avoids the possible side effects associated with systemic therapy. It remains unclear whether more severe disease will respond adequately to topical therapy alone. Crown Copyright © 2016. Published by Elsevier Inc. All rights reserved.

Pyoderma gangrenosum (PG) is a rare inflammatory neutrophilic dermatosis for which accurate epidemiological data are limited and therapy remains a challenge. The primary study aim was to examine all cases of PG observed in our regional department over a 15-year period in order to describe the relevant characteristics and outcome under therapy. The medical records of all patients with PG from 1997 to 2012 in the Marne department of France were studied retrospectively. Clinical and histological characteristics, comorbidities, therapeutic modalities and outcome were analysed. Forty-two patients were included (30 women, 12 men). A classical, ulcerative form was found in 39 cases and PG was multifocal in 28 cases. The number of lesions did not differ according to age or the presence of comorbidities. The most frequent first-line treatments were doxycycline (23 cases) and oral corticosteroids (15 cases), regardless of age, number of lesions or existence of comorbidities. Complete remission of PG was obtained in 38 cases (median time to remission: 3 months), with relapse occurring in 17 patients (median time to relapse: 12 months after treatment withdrawal). After a median follow-up of 46 months, 8 patients had died (median time to death: 26 months after treatment initiation). This is the first large French series of patients presenting PG and enabling determination of the annual incidence within the Marne department at around 4.6 cases/1000,000 inhabitants. Our study illustrates the value of first-line treatment with tetracycline, which merits confirmation by further prospective, controlled studies. Copyright © 2015 Elsevier Masson SAS.

A 21-year-old housewife presented to the authors' clinic in 2009 with recurrent papulovesicular and pustular eruptions on the index an ring fingers of the left hand accompanied by throbbing pain that had been active for the past 10 years. The condition did not respond to topical and/or systemic treatment. There was neither a personal/family history of psoriasis nor any other systemic disease. The sk surface of the patient's left hand was marked by the presence of multiple pustules located over an erythematous background, affecting th ring and adjoining middle fingers, with crusting prominent in places along the tips (Figure 1). Gram-stained smears prepared from th purulent specimen revealed Gram-positive cocci in clusters. Potassium hydroxide (KOH) examination of the pustules did not show a fungal elements. In vitro culture of the same specimen yielded growth of Staphylococcus aureus, which was found to be sensitive to almo all conventional antibiotics on aerobic culture. Sections prepared from the skin of the tip of the patient's finger showed marked epithelial hyperplasia with uniform elongation of rete ridges and supra-papillary thinning of the epidermis. There was hyperkeratosis with foci of mounds of parakeratosis. Spongiosis with neutrophilic infiltration and microabscess formation were prominent. The dermis showed perivascular lymphohistiocytic infiltrate (Figure 2A and 2B). No organism was identified on special stains. Results from hemography and liver and renal function tests were within normal limits. The diagnosis of acrodermatitis continua of Hallopeau (ACH) was made, in keeping with the findings. The patient received ceftriaxone 1.0 g and tazobactam 125 mg by slow intravenous infusion for 3 consecutive days, following which there was complete regression of the lesions. After cessation of therapy, there was complete recurrence.

IL-36 cytokines have recently emerged as mediators of inflammation in autoimmune conditions including psoriasis vulgaris (PsV) and generalized pustular psoriasis (GPP). This study used RNA-seq to profile the transcriptome of primary epidermal keratinocytes (KCs) treated with IL-1B, IL-36A, IL-36B, or IL-36G. We identified some early IL-1B-specific responses (8 h posttreatment), but nearly all late IL-1B responses were replicated by IL-36 cytokines (24 h posttreatment). Type I and II interferon genes exhibited time-dependent response patterns, with early induction (8 h) followed by no response or repression (24 h). Altogether, we identified 225 differentially expressed genes (DEGs) with shared responses to all 4 cytokines at both time points (8 and 24 h). These involved upregulation of ligands ( IL1A, IL1B , and IL36G ) and activating proteases ( CTSS ) but also upregulation of inhibitors such as IL1RN and IL36RN . Shared IL-1B/IL-36 DEGs overlapped significantly with genes altered in PsV and GPP skin lesions, as well as genes near GWAS loci linked to autoimmune and autoinflammatory diseases (e.g., PsV, psoriatic arthritis, inflammatory bowel disease, and primary biliary cholangitis). Inactivation of MyD88 adapter protein using CRISPR/Cas9 completely abolished expression responses of such DEGs to IL-1B and IL-36G stimulation. These results provide a global view of IL-1B and IL-36 expression responses in epidermal KCs with fine-scale characterization of time-dependent and cytokine-specific response patterns. Our findings support an important role for IL-1B and IL-36 in autoimmune or autoinflammatory conditions and show that MyD88 adaptor protein mediates shared IL-1B/IL-36 responses.

Depending on the very nail structure involved, different clinical nail alterations can be observed. Irritation of the apical matrix results in psoriatic pits, mid-matrix involvement may cause leukonychia, whole matrix affection may lead to red lunulae or severe nail dystrophy, nail bed involvement may cause salmon spots, subungual hyperkeratosis, and splinter hemorrhages, and psoriasis of the distal nail bed and hyponychium causes onycholysis whereas that of the proximal nail fold causes psoriatic paronychia. The more extensive the involvement, the more severe is the nail destruction. Pustular psoriasis may be seen as yellow spots under the nail or, in case of acrodermatitis continua suppurativa, as an insidious progressive loss of the nail organ. Nail psoriasis has a severe impact on quality of life and may interfere with professional and other activities. Management includes patient counseling, avoidance of stress and strain to the nail apparatus, and different types of treatment. Topical therapy may be tried but is rarely sufficiently efficient. Perilesional injections with corticosteroids and methotrexate are often beneficial but may be painful and cannot be applied to many nails. All systemic treatments clearing widespread skin lesions usually also clear the nail lesions. Recently, biologicals were introduced into nail psoriasis treatment and found to be very effective. However, their use is restricted to severe cases due to high cost and potential systemic adverse effects. Keywords: nail psoriasis, etiology, pathology, quality of life, impact, treatment

Similarly to psoriasis in adults, recent research has linked psoriasis to several comorbidities in children. The aim of this study was therefore to describe comorbidities associated with pediatric psoriasis, to investigate their relationship with psoriasis characteristics and severity, and to perform a review of the literature. A cross-sectional study was performed on a sample of Moroccan children with psoriasis, in 2014-2016. A total of 64 pediatric psoriasis patients had metabolic comorbidities in association with psoriasis; 20 children had non-metabolic comorbidities; and 76 children had no comorbidity. The metabolic comorbidities were as follows: abdominal obesity, 40% (n = 64); overweight, 12.5% (n = 20); metabolic syndrome, 3.7% (n = 6); and dyslipidemia, 3.1% (n = 5); the non-metabolic comorbidities were atopy, 4.3% (n = 7); epilepsy, 3.1% (n = 5); celiac disease, 1.8% (n = 3); vitiligo, 1.8% (n = 3); alopecia ariata, 0.6% (n = 1); and valvular cardiopathy, 0.6% (n = 1). No cases of diabetes mellitus, obesity, or high blood pressure were recorded. Significant factors associated with metabolic comorbidity were extended psoriasis vulgaris >10% (P = 0.01; OR, 2.19), severe psoriasis especially pustular and erythroderma (P = 0.018; OR, 2), nail involvement (P = 0.016; OR, 1.5), face involvement (P = 0.01; OR, 1,59), resistance to topical treatment (P = 0.003; OR, 2.5) and alteration of quality of life (P = 0.02; OR, 1,7). There was no significant risk factor associated with non-metabolic comorbidity. Given the frequent association of pediatric psoriasis with many disorders, these comorbidities should be investigated and identified so that they can be taken into account in the management of psoriasis in order to avoid treatment failure. Regular follow up should be carried out in patients at risk of metabolic comorbidity. © 2017 Japan Pediatric Society.

Interleukin (IL)-36RN, previously known as IL1-F5 and IL-1δ, shares a 360-kb region of chromosome 2q13 with members of IL-1 systems. IL-36RN encodes an anti-inflammatory cytokine, IL-36 receptor antagonist (IL-36Ra). In spite of IL-36Ra showing the highest homology to IL-1 receptor (IL-1R) antagonist, it differs from the latter in aspects including its binding to IL-lRrp2 but not to IL-1R1. IL-36RN is mainly expressed in epithelial cells and has important roles in inflammatory diseases. In the present study, IL-36RN was identified in the genomes of 27 species, including human, chimpanzee, mouse, horse and dolphin. Human IL-36RN was mainly expressed in the eye, head and neck, fetal heart, lung, testis, cervix and placenta; furthermore, it was highly expressed in bladder and parathyroid tumors. Furthermore, a total of 30 single nucleotide polymorphisms causing missense mutations were determined, which are considered to be the causes of various diseases, such as generalized pustular psoriasis. In addition, the link between IL-36RN and the prognosis of certain cancer types was revealed through meta-analysis. Tumor-associated transcriptional factors c-Fos, activator protein-1, c-Jun and nuclear factor κB were found to bind to the upstream region in the IL-36RN gene. This may indicate that IL-36RN is involved in tumorigenesis and tumor progression through the regulation of tumor-associated transcriptional factors. The present study identified IL-36RN in various species and investigated the associations between IL-36RN and cancer prognosis, which would determine whether IL-36RN drove the evolution of the various species with regard to tumorigenesis.

Full Text Available The incidence of syphilis has historically been cyclical in nature, often in relation to the rise and fall of public health initiatives directed toward eradication along with social attitudes toward sexual practices. The incidence of syphilis has increased by 15% in the last 6 years in the United States, with similar increases worldwide. Herein, we present an atypical case of syphilis presenting with severe septic shock and multiple anogenital lesions in an immunocompetent host. A 22-year-old male with no significant past medical history presented with fevers, chills, sore throat, diaphoresis, and diarrhea. He was febrile, tachycardic, hypotensive, and unresponsive to fluid resuscitation requiring short-term vasopressor support. Physical exam revealed diffuse lymphadenopathy; lower extremity macular rash involving the soles of the feet; papular non-pustular lesions on the scrotum; and a 0.5 cm non-tender irregular, healing lesion on the shaft of the penis. Laboratory analysis was significant for leukocytosis and elevated creatinine. Serum screening rapid plasma reagin was positive, and further testing revealed a titer of 1:32, with confirmation via fluorescent treponemal antibody absorption test. The patient was diagnosed with secondary syphilis, which was determined to be the underlying etiology of the sepsis as all other serological evaluations were negative. He was treated with penicillin G benzathine 2.4 million units intramuscular and supportive management, with improvement of symptoms. The patient engaged in high-risk sexual behaviors, including prior unprotected sexual contact with males. New research indicates that up to one-third of patients may present with atypical cutaneous manifestations, as demonstrated by this patient. It is important for physicians to familiarize themselves with the varied clinical presentations of syphilis, which include multiple anogenital lesions and tender primary lesions in primary or secondary syphilis.

Between July and December 1994, 25 patients with MRSA bacteraemia were treated at the Hospital Kuala Lumpur, a tertiary hospital in Malaysia with 3000 beds. The patients included 15 males and 10 females whose mean age was 46.7 years (range 13-75). The sources of their MRSA were: Urology/Nephrology, 11; General ICU, six; Orthopaedic, four; Medicine, three; Surgery, one. Their underlying diseases were: end-stage and chronic renal failure, 11; burns, three; acute necrotising pancreatitis, two; haematological malignancies, two; and one each of fracture of the neck of the femur, pustular psoriasis, alcoholic cirrhosis, liver abscess, peptic ulcer (antrectomy), choledochol cyst, and abdominal aneurysm with gangrene of the legs. Six patients were also diabetic. A total of 19 infections were considered nosocomial. The duration of hospital stay ranged from one to 60 days, mean 16 days. On the day of blood culture, 20 patients (80%) were febrile and 15(60%) had leucocytosis. A total of 14 patients were considered to have received prolonged broad-spectrum antibiotics before the bacteraemia; of these, 11 had had either a third-generation cephalosporin and/or a quinolone. The primary foci of infection were: vascular access dialysis catheters, six; infected AV fistulae, three; non-surgical wounds, five; orthopaedic pin, one; multiple venous lines and catheters, nine; unknown, one. The sensitivities to anti-MRSA antibiotics were: vancomycin, 100%; fusidic acid, 96%; rifampicin, 96%; ciprofloxacin and perfloxacin 28% each. In all, 13 patients (52%) eventually died; nine of these deaths were directly attributed to MRSA bacteraemia. The microbiological eradication rate was 88%. Mortality was significantly associated with duration of hospital stay and failure to remove the infected catheters/peripheral lines after the development of MRSA bacteraemia.

Cool tropical sea surface temperatures (SSTs) are reported for warm Paleogene greenhouse climates based on the δ18O of planktonic foraminiferal tests. These results are difficult to reconcile with models of greenhouse gas-forced climate. It has been suggested that this "cool tropics paradox" arises from postdepositional alteration of foraminiferal calcite, yielding erroneously high δ18O values. Recrystallization of foraminiferal tests is cryptic and difficult to quantify, and the compilation of robust δ18O records from moderately altered material remains challenging. Scanning electron microscopy of planktonic foraminiferal chamber-wall cross sections reveals that the basal area of muricae, pustular outgrowths on the chamber walls of species belonging to the genus Morozovella, contain no mural pores and may be less susceptible to postdepositional alteration. We analyzed the δ18O in muricae bases of morozovellids from the central Pacific (Ocean Drilling Program Site 865) by ion microprobe using 10 μm pits with an analytical reproducibility of ±0.34‰ (2 standard deviations). In situ measurements of δ18O in these domains yield consistently lower values than those published for conventional multispecimen analyses. Assuming that the original δ18O is largely preserved in the basal areas of muricae, this new δ18O record indicates Early Paleogene (˜49-56 Ma) tropical SSTs in the central Pacific were 4°-8°C higher than inferred from the previously published δ18O record and that SSTs reached at least ˜33°C during the Paleocene-Eocene thermal maximum. This study demonstrates the utility of ion microprobe analysis for generating more reliable paleoclimate records from moderately altered foraminiferal tests preserved in deep-sea sediments.

Invasive mycoses are an important cause of illness and death in immunocompromised patients. Infections with molds other than aspergilli have been increasingly seen in patients with hematologic cancers, but epidemics of these infections have not yet been reported. To describe an outbreak of invasive mycoses with Paecilomyces lilacinus in severely neutropenic patients. An outbreak investigation. The hematology-oncology isolation and bone marrow transplantation unit of the University Hospital, Basel, Switzerland. 25 consecutive patients admitted between 17 August 1993 (the date of the first manifestation of P. lilacinus infection) and 31 October 1993 (when the unit was closed). Clinical and microbiological data, including histologic findings; cultures from several patient sites; and environmental examinations of potential airborne, parenteral, enteric, and horizontal routes of transmission. Infections were defined by the isolation of P. lilacinus from clinically evident skin eruptions. 12 of the 25 patients (48%) were infected or colonized. Nine patients (36%), including all bone marrow transplant recipients, had documented invasive P. lilacinus infections. All 9 infected patients had papular, pustular, or necrotic skin eruptions. Two patients with severe graft-versus-host disease died with refractory fungal disease; 1 also had microbiologically documented endophthalmitis and kidney infiltrates. Seven affected patients no longer had P. lilacinus after recovery of bone marrow function. The organism was resistant in vitro to amphotericin B, itraconazole, and fluconazole. Patients did not respond clinically to these agents. The outbreak was ultimately traced to a contaminated, commercially available, pharmaceutically prepared skin lotion. The outbreak ended after the skin lotion was recalled and has not recurred after a follow-up period of 2 years. Contaminated skin lotion is a potential cause of opportunistic fungal infections in immunocompromised hosts. Paecilomyces

Psoralen + ultraviolet A (PUVA) therapy is an established modality for psoriasis. As India is a tropical country that has good availability of natural sunlight psoralen + sunlight (PUVAsol) may be a more convenient option. To compare the efficacy and cost-effectiveness of PUVA versus PUVAsol in chronic plaque psoriasis. Cases of chronic plaque psoriasis with body surface area ≥10% or Psoriasis Area and Severity Index (PASI) ≥10, excluding erythrodermic or pustular psoriasis, were randomized to receive either PUVA or PUVAsol, with endpoint being the achievement of PASI 90 or completion of 12 weeks treatment, whichever is earlier. Cost analysis was also undertaken. Thirty-six cases (16 in PUVA and 20 in PUVAsol group) completed treatment. In the PUVA group, 15 cases (93.75%) responded to therapy while in the PUVAsol group, 15 (75%) responded (P = 0.29). Mean baseline PASI in the PUVA and PUVAsol groups was 16 and 14.4, respectively, and at endpoint was 1.62 and 3.77. There was a significantly greater reduction in PASI in the PUVA group at 2 and 4 weeks but at 8 and 12 weeks and endpoint, it was comparable. Treatment failure occurred in 6.25% and 25% of cases respectively (P = 0.29). Side effects were higher with PUVA. Total cost of therapy was significantly higher in the PUVA group (P = 0.002). Cost-effectiveness ratio was US$0.72 with PUVA and US$0.37 with PUVAsol. Both PUVA and PUVAsol were equally efficacious, with PUVAsol being twice as cost effective. Hence, PUVAsol may be recommended as treatment for psoriasis in a developing economy such as India. © 2013 The International Society of Dermatology.

, powder of the commercial capsules (Dalacin®) was diluted in petrolatum (pet.) and water (aq.), resulting in a final 1% clindamycin dilution. Parenteral clindamycin preparations were used in therapeutic concentrations for prick tests (150 mg/mL) and dilutions in saline of 1/100 and 1/10 for the ID test. Other authors have reported that these concentrations do not seem to irritate the skin (3-6). Prick and ID tests were assessed after 20 min and 24 hours, respectively. Patch tests were removed after the 2nd day, and late reactions were evaluated on day 2 and day 4. Prick and ID test results after 20 min were negative. Late results of ID tests with clindamycin (1.5 and 15 mg/mL) were positive: erythematous infiltrated papules about 7×7 mm and 18×15 mm were observed at 24 hours and lasted until the 8th day. Patch tests with clindamycin 1% in pet. and 1% in aq. were also positive (+ on day 2 and day 4). Positive late skin tests suggested delayed-type non-IgE-mediated allergic clindamycin hypersensitivity. Oral challenge tests are considered to be the gold standard to establish or exclude drug hypersensitivity. Due to the positive result of late skin test to clindamycin, oral challenge was not performed in our patient (3,5). The Koebner isomorphic phenomenon has been described in cutaneous reactions induced by drugs, such as antibiotics and chemotherapy. Chronic pressure on the skin is probably involved in the onset of skin lesions in hand-foot eruptions induced by tyrosine kinase inhibitors (sorafenib and sutinib). Solar exposure and cutaneous trauma also seem to play a role in the location of papulopustular eruptions caused by endothelial growth factor receptor inhibitors (erlotinib) (7). More frequent involvement in traumatized skin and surgical scars has been reported in the context of linear IgA bullous dermatosis and leukocytoclastic vasculitis triggered by vancomycin and cefuroxime (8).

The Acquired Immunodeficiency Syndrome (AIDS) constitutes a sub-epidemic in Brazil. Due to the increasing number of women infected by the virus, the vertical transmission increased substantially, and due to the lack of adequate prophylactic treatment, many children are infected and show manifestations of the disease in early ages. Multiple systems are affected by the HIV virus, and the skin is often the first organ to be involved. The objective of this study is to analyze the clinic, dermatological and epidemiological profiles of children carriers of the virus in the City of Manaus aiming at identifying the most frequent dermatoses that affect these children and try to relate these dermatoses to the immunologic deterioration. A study was conducted where children carriers of the HIV virus from the Fundação Alfredo da Matta and Fundação de Medicina Tropical were studied from March 2007 to July 2008. These children were submitted to dermatological and laboratorial exams such as viral load dosage and CD4+ and CD8+ counts. During the study period, 70 HIV + children were examined; all of them had AIDS and had been contaminated by vertical transmission. The average number of dermatoses by children was 1.73, and 95.5% had at least one dermatosis during the study period. The most frequent manifestations were atopic dermatitis (22.9%), childhood prurigo (20%) and warts (18,6%). Children with HIV/AIDS have more skin disorders than children without HIV/AIDS. There was no statistical difference between the children in the group using ARVT and the group that wasn't using it.

Acne is a multifactorial dermatosis, which is influenced not only by hormones but also by the biochemical relationship between them and the pilosebaceous unit. Inflammatory cytokines, chemokines, active oxygen, and zinc are known to be associated with the development of acne. Further, steroid metabolism is known as one of the important factors related to sebum secretion and comedone formation in acne. However, there is a lack of studies comparing these human biomarkers between healthy individuals and patients with acne. In particular, no study has investigated the relationship between human biomarkers and patterns of acne yet.The purpose of this study is to investigate diagnostic human biomarkers in acne by comparing the biological and metabolic biomarkers between healthy individuals and patients with acne and identify the relationship between human biomarkers and patterns of acne.This study is a protocol for a cross-sectional study. Forty healthy participants and 60 patients with acne will be recruited at 1 center. We will collect their blood samples and analyze the molecular biological and metabolic biomarkers (cytokines, chemokines, reactive oxygen species, corticotropin-releasing hormone, zinc, amino acid, 1-carbon metabolite, lipid metabolite, etc.). Further, we will administer questionnaires regarding their diet, sleep, stress, and other factors relating to acne and measure their skin elasticity.The study protocol was approved by the Institutional Review Board of Oriental Medical Hospital at Kyung Hee Medical Center (KOMCIRB-161118-HR-062). Written informed consent will be obtained from all the participants. The trial was registered in the Clinical Research Information Service, Republic of Korea: KCT0002212.This trial will provide evidence regarding diagnostic human biomarkers in acne and the relationship between the human biomarkers and patterns of acne.

Full Text Available BACKGROUND Obesity is a major concern in our era. Obese individuals have numerous physiological changes which predispose them to many dermatological conditions. This study was done to find the common dermatoses associated in adults with a BMI of > 30 kg/m2 who presented to the Skin Outpatient Department of Coimbatore Medical College Hospital. OBJECTIVES To study the prevalence of various dermatological manifestations of obesity, age, sex distribution, morphology of individual lesions associated with obesity and their association with BMI and lipid profile. METHODOLOGY This is a descriptive study conducted from August 2014 to July 2015. Hundred patients with age > 12 yrs. and BMI > 30 kg/m2 were selected and included in the study. Diabetes was ruled out and lipid profile was carried out for all patients. Other necessary investigations like biopsy, KOH mount and immunofluorescence were done for relevant cases. RESULTS There were 100 patients with 169 dermatoses seen in the study. Male female ratio was 1.5: 1. Most cases belonged to the age group of 31-40. Nearly 76% all cases were in grade 1 obesity according to their BMI levels. Only 3 cases were seen in grade 3 obesity. Lipid profile alterations were seen in 29% of all cases. Skin tag was the most common dermatosis seen in the study followed by acanthosis nigricans, plantar hyperkeratosis and striae. CONCLUSION Severity of obesity also determines the nature of lesions occurring in the patients. Early identification of these conditions can be useful in preventing the deleterious effects of obesity on the body. Treatment of lipid profile abnormalities in addition to weight reduction can decrease the occurrence of these dermatoses.

The interleukin (IL)-1 pathway has been identified as being involved in inflammatory and neoplastic skin diseases such as psoriasis, atopic dermatitis, neutrophilic dermatosis, melanoma, and squamous cell carcinoma. Drugs developed to target the IL-1 pathway are currently used to treat these pathologies, and although they are becoming more selective, they are not exempt from adverse events and high costs. Integrating the best research evidence with clinical experience and patient needs has been shown to improve care, health, and cost outcomes. This is because evidence-based guidelines rank interventions according to cost-effectiveness. However, evidence on this topic is scarce for several reasons. First, although randomized clinical trials currently provide the best evidence, they are not always available. Second, there are no secondary scientific studies that summarize the use of IL-1-targeting agents in dermatology. We therefore sought to develop an a priori protocol for broadly reviewing the available evidence on the use of IL-1-targeting drugs in the treatment of dermatological diseases. We used the latest methodology to perform a scoping review as described in the Joanna Briggs Institute manual. Developing and applying a methodology for evidence synthesis promotes reproducibility and increases the validity of secondary scientific investigations, making it the optimal strategy for scientifically synthesizing a broad field such as the indications for and the mechanisms of action, efficacies, safety, and costs of IL-1-targeting drugs in the treatment of dermatological diseases. Quantitative synthesis facilitates the detection of knowledge gaps and the identification of new questions that can be addressed through systematic reviews. We present an a priori protocol for exploring the available evidence on this topic.

Full Text Available In humans, congenital and hereditary skin diseases associated with epidermal cell-cell separation (acantholysis are very rare, and spontaneous animal models of these diseases are exceptional. Our objectives are to report a novel congenital acantholytic dermatosis that developed in Chesapeake Bay retriever dogs. Nine affected puppies in four different litters were born to eight closely related clinically normal dogs. The disease transmission was consistent with an autosomal recessive mode of inheritance. Clinical signs occurred immediately after birth with superficial epidermal layers sloughing upon pressure. At three month of age, dogs exhibited recurrent superficial skin sloughing and erosions at areas of friction and mucocutaneous junctions; their coat was also finer than normal and there were patches of partial hair loss. At birth, histopathology revealed severe suprabasal acantholysis, which became less severe with ageing. Electron microscopy demonstrated a reduced number of partially formed desmosomes with detached and aggregated keratin intermediate filaments. Immunostaining for desmosomal adhesion molecules revealed a complete lack of staining for plakophilin-1 and anomalies in the distribution of desmoplakin and keratins 10 and 14. Sequencing revealed a homozygous splice donor site mutation within the first intron of PKP1 resulting in a premature stop codon, thereby explaining the inability to detect plakophilin-1 in the skin. Altogether, the clinical and pathological findings, along with the PKP1 mutation, were consistent with the diagnosis of ectodermal dysplasia-skin fragility syndrome with plakophilin-1 deficiency. This is the first occurrence of ectodermal dysplasia-skin fragility syndrome in an animal species. Controlled mating of carrier dogs would yield puppies that could, in theory, be tested for gene therapy of this rare but severe skin disease of children.

Full Text Available Background: Seborrheic keratosis (SK is the most common benign epidermal tumor of the skin. Even though SK has been well characterized clinically, dermoscopically, and histopathologically, data regarding clinical dermoscopic and histopathological correlation of different types of SK are inadequate. Aim: We carried out this study to establish any correlation between the clinical, dermoscopic, and histopathological appearance of SK and its variants. Methods: This was a descriptive study. Patients with SK were evaluated with respect to age, sex, family history of similar lesions, site of lesions, and symptoms associated with the lesions. Dermoscopy was performed in all cases. Biopsies were taken from the lesions and assessed for histopathology. Results: The most common age group affected by SK was 31-50 years (42%. A female preponderance of 76% was seen. Majority of our patients had a positive family history (62%, though Sun exposure was not seen to be a major factor. The most common clinical variant was common SK (CSK (46%. The most common dermoscopic findings seen in CSK were comedo-like (CL openings, fissures and ridges (FR, and milia-like (ML cysts. Dermatosis papulosa nigra and pedunculated SK had characteristic FR and CL openings on dermoscopy. Stucco keratoses showed network-like (NL structures and sharp demarcation. CL opening on dermoscopy corresponded to papillomatosis and pigmentation, ML cysts corresponded to horn cysts, FR corresponded to papillomatosis, and NL structures corresponded to an increase in basal layer pigmentation. Conclusions: This study emphasizes the use of dermoscopy in improving the diagnostic accuracy of SK. The correlation between the various histological and dermoscopic features is described.

Rosacea is a chronic inflammatory dermatosis affecting >2% of the population. Willingness to pay (WTP) is a well established method which reflects the individual burden of disease. Evaluation of WTP and quality of life (QoL) in patients with rosacea. Nationwide postal survey on adult patients with rosacea affiliated with the German rosacea patient advocacy group. WTP was evaluated by three standardized items and compared to historical data on vitiligo (n = 1023). QoL was assessed using the Dermatology Life Quality Index (DLQI). Data from n = 475 rosacea patients (79.9% women, mean age 56.3, range 26-90) were analysed. On average, patients were willing to pay € 2880 (median € 500) for complete healing compared with € 7360 (median € 3000) in vitiligo. Relative WTP was higher in women; the highest sums were registered for the age group 21-30 years. The extent of facial involvement predicted a higher relative WTP, whereas WTP decreased with the duration of symptoms and age. Mean DLQI total score was 4.3 compared to 7.0 in vitiligo. In rosacea, the highest values were observed in patients 10) were less frequent (11%) than in vitiligo (24.6%). The correlation between WTP and DLQI was significant (e.g. r = 0.249, P = 0.000 for relative WTP). Rosacea patients show a moderate WTP and average QoL reduction is mild. WTP proved to be a valid tool to assess patients' burden of disease. Patient education and the development of effective treatment options might still improve patients' satisfaction. © 2012 The Authors.

Objective. Granuloma annulare is an uncommon benign inflammatory dermatosis characterized by the formation of dermal papules with a tendency to form rings. There are several clinically distinct forms. The subcutaneous form is the most frequently encountered by radiologists, with the lesion presenting as a superficial mass. There are only a few scattered reports of the imaging appearance of this entity in the literature. We report the radiologic appearance of five cases of subcutaneous granuloma annulare. Design and patients. The radiologic images of five patients (three male, two female) with subcutaneous granuloma annulare were retrospectively studied. Mean patient age was 6.4 years (range, 2-13 years). The lesions occurred in the lower leg (two), foot, forearm, and hand. MR images were available for all lesions, gadolinium-enhanced imaging in three cases, radiographs in four, and bone scintigraphy in one. Results. Radiographs showed unmineralized nodular masses localized to the subcutaneous adipose tissue. The size range, in greatest dimension on imaging studies, was 1-4 cm. MR images show a mass with relatively decreased signal intensity on all pulse sequences, with variable but generally relatively well defined margins. There was extensive diffuse enhancement following gadolinium administration. Conclusion. The radiologic appearance of subcutaneous granuloma annulare is characteristic, typically demonstrating a nodular soft-tissue mass involving the subcutaneous adipose tissue. MR images show a mass with relatively decreased signal intensity on all pulse sequences and variable but generally well defined margins. There is extensive diffuse enhancement following gadolinium administration. Radiographs show a soft-tissue mass or soft-tissue swelling without evidence of bone involvement or mineralization. This radiologic appearance in a young individual is highly suggestive of subcutaneous granuloma annulare. (orig.)
