Tylosin tablets (20 mg/kg, q12h) were administered orally to 21 dogs with superficial or deep staphylococcal pyodermas. Response to therapy was excellent in 90.5% of the dogs, and in vitro susceptibility testing correlated perfectly with therapeutic response. Duration of therapy varied from 17 to 91 days, with an average of 33 days. Relapses occurred in 28.6% of the dogs within a three-month period. No side effects were reported. Under the conditions of the study, tylosin was an effective and safe antibiotic for the treatment of staphylococcal pyoderma in dogs. PMID:7994702

Pyoderma gangrenosum is an uncommon ulcerative skin disorder that occurs in all age groups. Approximately 4% of patients are infants and children. There are several notable differences between the childhood and adult manifestations of the disease, including the distribution of lesions and associated disorders. We reviewed the childhood cases (< or = 18 yrs of age) of unequivocal pyoderma gangrenosum in the English literature and tabulated the trends in clinical features, associated disorders, and therapy. We report our 3-week-old patient, the youngest documented case. Of the 46 patients, only 4 were less than 1 year of age. A systemic illness was present in 74% of the older children, most commonly, ulcerative colitis. Only one infant had an associated problem (HIV+) at the time of onset. Infants appear to have an unusual distribution of perianal and genital lesions not often described in other age groups. Our review suggests that pyoderma gangrenosum in children has a similar clinical appearance to that in adults. It is associated with some of the same underlying disorders, but with different frequencies. The distribution of lesions in children is similar, often involving the lower extremities, but pyoderma gangrenosum of the head and face appears to be more common in children. Infants may have ulcers in genital and perianal areas. The most frequently prescribed treatment for children is systemic corticosteroids, which generally are very effective.

We present a unique case of a 36-year-old male who developed more than 20 pyoderma gangrenosum (PG) ulcers showing on histopathology a dense inflammatory infiltrate composed of histiocytoid mononuclear immature cells with a strong positivity for myeloperoxidase and Leder stain, suggesting a myeloid lineage in the absence of a concomitant myeloproliferative disorder. Histiocytoid Sweet syndrome (SS) is now recognized as a histological subtype of SS. Although PG and SS belong to the spectrum of neutrophilic diseases, to the best of our knowledge, this is the first case of a "Histiocytoid pyoderma gangrenosum" encompassing immature granulocytes in the absence of leukemia cutis. © 2017 John Wiley & Sons A/S.

Peristomal pyoderma gangrenosum (PPG) is a rare subtype of pyoderma gangrenosum that is characterized by painful, necrotic ulcerations occurring in the area surrounding an abdominal stoma. PPG is typically seen in younger patients with active inflammatory bowel disease. The etiology and pathogenesis is largely unknown and risk factors are not well defined. Therapy typically involves a combination of aggressive local wound care and systemic medications. Diagnosis and management of PPG can be difficult and data on treatment are limited. We present a case of severe postoperative peristomal recalcitrant to conventional therapy successfully treated with intravenous immune globulin. PMID:25802252

PASH syndrome (pyoderma gangrenosum, acne, and suppurative hidradenitis) forms part of the spectrum of autoinflammatory diseases. We report an unusual case of PASH syndrome in a patient with end-stagerenal disease (ESRD) who was successfully treated with the tumor necrosis factor inhibitor, adalimumab. The case underscores the challenges associatedwith the treatment of PASH syndrome as well as the ongoing search to establish a genetic basis for the syndrome. Renal impairment has been reported in association with pyoderma gangrenosum but has notbeen described in PASH syndrome. We believe this to be the first reported case of a patient who developed PASH syndrome in the setting of ESRD.

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 4-year-old ball python was presented 3 weeks after multiple bite wounds from a prey rat with large skin lesions, a concurrent deep bacterial pyoderma and clinical signs for septicemia, including neurolo -gical symptoms. Affected tissue separated from the underlying muscular layer revealing parts of the muscles. Clinical examination and cyto -logy was consistent with bacterial pyoderma; septicemia was an additional tentative clinical diagnosis. Empirical lincomycin and marbo -floxacin (bacterial culture revealed a multi-resistant Stenotrophomonas maltophilia susceptible to fluoroquinolones) treatment improved the patient's general condition but skin wounds deteriorated to multifocal eschars with intracellular rods. Further diagnostics were limited for financial reasons, euthanasia was considered. Cold atmospheric pressure plasma (CAPP) therapy was performed six times in 4 weeks. Within 1 week, inflammatory symptoms resolved. Re-epithelialization was completed few weeks later. In the following year, the snake sloughed three times without any signs of dysecdysis. CAPP therapy may offer a viable treatment option for bacterial (especially multiresistant) pyoderma and necrotizing dermatitis in snakes. Schattauer GmbH.

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.

The clinical efficacy of a surgical scrub containing 2% chlorhexidine acetate (2CA; Nolvasan® Surgical Scrub; Fort Dodge Animal Health, USA) was evaluated for the topical management of canine superficial pyoderma. The first study was a randomized, double-blind, controlled trial. The control was a shampoo containing 4% chlorhexidine gluconate (4CG; Skin Clinic Shampoo; CHD MEDICS, Goyang, Korea). Ten dogs with symmetrical lesions of canine superficial pyoderma were allocated to receive either 2CA or the control shampoo applied to either side of the body twice weekly for 1 week. Both the owners and the investigators subjectively scored skin lesions including pruritus, erythema, crusted papules and scales on a scale of 0-3. The 2CA and 4CG resulted in almost the same degree of improvement of skin lesions, and there were no significant differences between the two groups. The second study was an open trial of 2CA monotherapy in eight dogs with cefalexin-resistant Staphylococcus intermedius group-associated superficial pyoderma. The 2CA monotherapy was applied every 2 days for 2 weeks. Five dogs improved with 2CA monotherapy, one partially improved and two did not. No adverse reactions were seen in either trial. This suggests that a 2CA surgical scrub could be a useful and safe topical adjunct therapy for dogs with superficial pyoderma involving cefalexin-resistant Staphylococcus intermedius group. © 2010 The Authors.

A 52-year-old woman with ulcerative colitis was admitted to our hospital for an ulcerative colitis flare-up under salazosulfapyridine therapy. The symptoms improved with high-dose corticosteroids. After prednisolone was tapered to 10 mg, the frequency of diarrhea increased. The diarrhea was accompanied by joint pain and a skin ulcer with abscess formation, which was diagnosed to be pyoderma gangrenosum. The patient was started on adalimumab. A positive response to the adalimumab therapy was observed after 2 weeks, during which time the ulcerative skin lesion healed completely, however, colonic mucosal healing was achieved at 2 months. Therefore, adalimumab appears to be an effective therapeutic option for patients with ulcerative colitis-associated pyoderma gangrenosum.

Pyoderma gangrenosum, acne and ulcerative colitis in a patient with a novel mutation in the PSTPIP1 gene.

Pyogenic sterile arthritis, pyoderma gangrenosum and acne (PAPA) syndrome is a rare hereditary, autosomal dominant, auto-inflammatory disease caused by mutations in the PSTPIP1 gene, which encodes proline-serine-threonine phosphatase interacting protein 1. The fact that PSTPIP1 is involved in immune regulation provides a rationale for treatment of this rare disease with interleukin (IL)-1 signalling blocking agents. We investigated a 33-year-old man with a long-standing history of ulcerative colitis, severe acne and recurrent skin ulcerations, and a 3-year history of a recalcitrant pustular rash. We used direct sequencing to search for mutations in the PSTPIP1 gene. Examination of biopsies obtained from pustules and skin ulcers revealed folliculitis and ulceration with a diffuse neutrophilic dermal infiltrate, consistent with a diagnosis of pyoderma gangrenosum. Because of the known association of acne and pyoderma gangrenosum in PAPA syndrome, we determined the entire coding sequence of the PSTPIP1 gene, and identified a hitherto unreported heterozygous mutation predicted to alter a highly conserved residue (p.G403R) and to be damaging to the protein function. Based on this finding, we initiated treatment with a human IL-1 receptor antagonist, anakinra, which led to a dramatic improvement in the patient's condition. We describe a novel mutation in PSTPIP1 resulting in pyoderma gangrenosum, acne and ulcerative colitis. This novel constellation of clinical manifestations, which we term 'PAC syndrome', suggests the need to regroup all PSTPIP1-associated phenotypes under one aetiological group. © 2015 British Association of Dermatologists.

Treatment of pyoderma gangrenosum complicating ulcerative colitis has in the past been frustrating and usually unsuccessful, frequently resulting in colectomy. Intralesional steroid therapy has been used off and on in a few patients, but the treatment is not widely known to gastroenterologists. We report two patients successfully treated for early pyoderma gangrenosum by intralesional injection of triamcinolone acetonide (Kenalog, 40 mg injection) together with conventional doses of systemic steroids. A single series of injections was sufficient to bring about healing of the lesions in both patients. The treatment permitted early discharge of patients from the hospital, and the skin lesions were completely healed within 2 months. The lesions have not recurred in follow-up examinations of 11/2 and 21/2 years, respectively. We hope that other physicians will find this approach equally effective.

Pyoderma gangrenosum is a rapidly developing cutaneous ulcer that is rare in the hand and may mimic a fulminating infection. The correct treatment is nonsurgical; surgery may actually incite a pathergic response worsening the condition. Misdiagnosis results in inappropriate treatment, unnecessary surgery, and even amputations. The records of 7 patients with pyoderma gangrenosum of the hand treated at 2 large academic medical centers between 1992 and 1999 were reviewed. There were 4 men and 3 women with an average age of 58 years (range, 32-81 years). Five patients had bilateral involvement. Minor trauma preceded the appearance of the lesions. An associated systemic disease was found in all patients with ulcerative colitis being the most common (3 patients). All patients initially had a misdiagnosis of infection. Thirteen misdiagnoses (range, 1-3/patient) resulted in 16 unnecessary surgeries (mean, 2.2/patient) including 4 amputations and 2 failed skin grafts. No surgical procedure resulted in clinical improvement. All cultures were negative. Several physicians (mean, 5; range, 3-7) examined each patient before the final diagnosis of pyoderma gangrenosum, which was made by, or in conjunction with, a dermatologist in all cases. The average time to clinical improvement after correct medical treatment was initiated was 5 days.

A 65-year-old man had tetraplegia caused by a cervical spinal cord injury, and could only lie in bed with a respirator. On the 14 th day of hospitalization, a rash developed on his back. The eruption grew rapidly, and became a giant erythematous plaque with ulcer, pustules, and red papules. Direct KOH examination showed branching Aspergillus hyphae. A slide culture showed subglobose shaped vesicles with phialides. Based on these findings, the case was diagnosed as primary pyoderma-like aspergillosis caused by Aspergillus fumigatus. He was treated with bifonazole and sulfadiazine silver, and one month later no Aspergillus hyphae were observed either by direct KOH examination or by culture. The patient died about 2 months later, however, because of aggravation of his general condition. Careful observation is necessary for compromised or unmoving patients with pyoderma-like aspergillosis.

Effects of Vedolizumab Therapy on Extraintestinal Manifestations in Inflammatory Bowel Disease.

Approximately 15-20% of ulcerative colitis patients and 20-40% of those with Crohn's disease experience extraintestinal manifestations (EIMs) of their inflammatory bowel disease (IBD). Clinicians who treat IBD must manage EIMs affecting multiple organs that variably correlate with intestinal disease activity. Vedolizumab is a monoclonal antibody for the treatment of IBD with a gut-selective mechanism of action. This report evaluates whether vedolizumab is an effective treatment of EIMs, given its gut-specific mechanism of action. We report 8 case studies of patients with various EIMs, including pyoderma gangrenosum, peripheral arthralgia/arthritis, axial arthropathies, erythema nodosum, and uveitis, who received vedolizumab therapy. Vedolizumab therapy was effective for pyoderma gangrenosum in ulcerative colitis, uveitis, erythema nodosum, polyarticular arthropathy, and ankylosing spondylitis/sacroiliitis but did not provide sustained benefit for the treatment of pyoderma gangrenosum in a patient with Crohn's disease. These cases demonstrate the potential of vedolizumab as a treatment of EIMs in patients with IBD.

Pyoderma gangrenosum following reduction mammaplasty

The failure of a postoperative local infection to resolve after appropriate antibiotic therapy should prompt consideration of other diagnoses. Reported here is a case of pyoderma gangrenosum, a rare necrotizing disorder, occurring after reduction mammaplasty. The clinical presentation was one of progressive wound deterioration with associated erythema and intense pain. After failure of antibiotic therapy and local wound care, tissue biopsy of the enlarging wound edge confirmed the diagnosis, which then responded rapidly to systemic steroid treatment. Given that the treatment for pyoderma gangrenosum is at odds with the standard treatment for an infection (steroids versus antibiotics), differentiating between the two diagnoses is vital to providing resolution of the process and limiting any untoward scarring resulting from the advancing open wounds that can develop. With this in mind, the physical signs and symptoms that characterize this condition and thus allow early diagnosis are presented, and treatment options discussed. PMID:19554230

Scrum kidney: epidemic pyoderma caused by a nephritogenic Streptococcus pyogenes in a rugby team.

PubMed

Ludlam, H; Cookson, B

1986-08-09

In December, 1984, an outbreak of pyoderma affected five scrum players in the St Thomas' Hospital rugby team. The causative organism, Streptococcus pyogenes, was acquired during a match against a team experiencing an outbreak of impetigo, and was transmitted to two front row players of another team a week later, and to two girlfriends of affected St Thomas' players a month later. The strain was M-type 49, tetracycline-resistant, and virulent. It caused salpingitis in a girlfriend and acute glomerulonephritis in one rugby player. No case of subclinical glomerulonephritis was detected in eight patients with pyoderma. Screening of the St Thomas' Hospital team revealed four further cases of non-streptococcal skin infection, with evidence for contemporaneous spread of Staphylococcus aureus. Teams should not field players with sepsis, and it may be advisable to apply a skin antiseptic to traumatised skin after the match.

Pyoderma gangrenosum is an inflammatory neutrophilic dermatosis. Current knowledge of this rare disease is limited owing to a lack of validated diagnostic criteria and large population studies. To evaluate the association of age with the clinical presentation and comorbidities of pyoderma gangrenosum. This was a multicenter retrospective cohort study performed at tertiary academic referral centers in urban settings. Adults (≥18 years) who were evaluated and diagnosed as having pyoderma gangrenosum at the Brigham and Women's and Massachusetts General Hospitals from 2000 to 2015 and the University of Pennsylvania Health System from 2006 to 2016 were included. Patient demographics, clinical features, medical comorbidities, and treatment. Of the 356 validated cases of pyoderma gangrenosum included in the study, 267 (75%) were women and 284 (84.8%) were white. The mean (SD) age at presentation was 51.6 (17.7) years. Pathergy was recorded in 100 patients (28.1%). A total of 238 patients (66.9%) had associated medical comorbidities: inflammatory bowel disease in 146 patients (41.0%); inflammatory arthritis in 73 patients (20.5%); solid organ malignant neoplasms in 23 patients (6.5%); hematologic malignant neoplasms in 21 patients (5.9%); and hematologic disorders, specifically monoclonal gammopathy of undetermined significance, myelodysplastic syndrome, and polycythemia vera in 17 patients (4.8%). When stratified by age, pathergy was more common in patients 65 years or older (36.3% vs 24.3%; P = .02). Inflammatory bowel disease was the only medical comorbidity that was more common in patients younger than 65 years (47.7% vs 26.6%; P < .001), while a number of medical comorbidities were more common in those 65 years or older, including rheumatoid arthritis (13.3% vs 6.2%; P = .03), ankylosing spondylitis (1.8% vs 0%; P = .04), solid organ malignant neoplasms (13.3% vs 3.3%; P < .001), hematologic malignant neoplasms (9.7% vs 4.1%; P = .04), and the aforementioned hematologic disorders (10.6% vs 2.1%; P < .001). Although clinical presentation in this large cohort was similar between different age groups, disease associations varied by age. The findings of this study may allow for a more focused, age-specific evaluation of patients with pyoderma gangrenosum.

The aim of this study was to investigate the presence of canine immunoglobulins (Ig) G against Demodex proteins in the sera of healthy dogs and of dogs with juvenile generalized demodicosis (CanJGD) with or without secondary pyoderma. Demodex mites were collected from dogs with CanJGD. Protein concentration was measured and a western blot technique was performed. Pooled sera from healthy dogs reacted mainly with antigen bands ranging from 55 to 72 kDa. Pooled sera from dogs with CanJGD without secondary pyoderma reacted either with 10 kDa antigen band or 55 to 72 kDa bands. Pooled sera from dogs with CanJGD with secondary pyoderma reacted only with a 10 kDa antigen band. The results of this study suggest that both healthy dogs and dogs with CanJGD develop a humoral response against different proteins of Demodex canis. Copyright © 2015 Elsevier Ltd.

The simultaneous occurrence of pyoderma gangrenosum (PG) and chronic granulomatous disease (CGD) is uncommon and few cases have been reported worldwide. PG is a rare, chronic, ulcerative, neutrophilic skin disease of unknown etiology that requires immunosuppressive treatment. CGD belongs to Primary Immune Deficiencies in which the main defect lies in an inability of the phagocytic cells to generate superoxide making patients susceptible to serious, potentially life-threatening bacterial and fungal infections. In this manuscript, we present a case of ulcerative pyoderma gangrenosum in a 28-year-old man with recent diagnosis of chronic granulomatous disease during hospitalization for resistant pulmonary tuberculosis complicated with Aspergillus infection. Second-line therapy with dapsone and intravenous immunoglobulin was initially administered but eventually corticosteroids were added to treatment because of disease progression and further ulceration. Patient's ulcers were gradually healed with no side effects. Corticosteroids could be used under close monitoring for the treatment of PG in a patient with CGD, despite the increased risk for infections.

CGD belongs to Primary Immune Deficiencies in which the main defect lies in an inability of the phagocytic cells to generate superoxide making patients susceptible to serious, potentially life-threatening bacterial and fungal infections. Diagnoses: In this manuscript, we present a case of ulcerative pyoderma gangrenosum in a 28-year-old man with recent diagnosis of chronic granulomatous disease during hospitalization for resistant pulmonary tuberculosis complicated with Aspergillus infection. Interventions: Second-line therapy with dapsone and intravenous immunoglobulin was initially administered but eventually corticosteroids were added to treatment because of disease progression and further ulceration. Outcomes: Patient's ulcers were gradually healed with no side effects. Lessons: Corticosteroids could be used under close monitoring for the treatment of PG in a patient with CGD, despite the increased risk for infections. PMID:28767612

Management of Facial Pyoderma Gangrenosum Using Platelet-Rich Fibrin: A Technical Report.

This report describes a case of local pyoderma gangrenosum that was treated with short-term immunosuppressive therapy and the topical application of platelet-rich fibrin (PRF). Medical treatment included oral corticosteroid therapy and topical treatment with PRF in solid and liquid form. This therapy initially led to the reduction of the ulcer's size and an improvement in symptoms, until the ulcer was completely healed after a few weeks. A relapse was treated with only the application of PRF to the affected tissue with excellent recovery. The efficacy of PRF as a guide for wound healing is a result of the continuous release of growth factors involved in tissue repair mechanisms. PRF has proved to be suitable for the management of facial pyoderma gangrenosum while allowing a reduction in systemic corticosteroid therapy. The ease of preparation, low cost, and outpatient use make PRF an optimal scaffold for tissue healing processes. Copyright © 2018 American Association of Oral and Maxillofacial Surgeons.

Pyoderma gangrenosum-like ulcers and cellulitis of the lower extremities associated with recurrent fevers in patients with X-linked (Bruton) agammaglobulinemia have been reported to be caused by Helicobacter bilis (formerly classified as Flexispira rappini and then Helicobacter strain flexispira taxon 8). Consistent themes in these reports are the difficulty in recovering this organism in blood and wound cultures and in maintaining isolates in vitro. We confirmed the presence of this organism in a patient's culture by using a novel application of gene amplification polymerase chain reaction and electrospray ionization time-of-flight mass spectrometry. An adolescent boy with X-linked agammaglobulinemia presented with indurated plaques and a chronic leg ulcer whose origin was strongly suspected to be an H bilis organism. Histologic analysis demonstrated positive Warthin-Starry staining of curvilinear rods, which grew in culture but failed to grow when subcultured. They could not be identified by conventional techniques. A combination of gene amplification by polymerase chain reaction and electrospray ionization time-of-flight mass spectrometry confirmed the identity of this organism. This novel technology was useful in the identification of a difficult-to-grow Helicobacter organism, the cause of pyoderma gangrenosum-like leg ulcers in patients with X-linked agammaglobulinemia. Correct identification of this organism as the cause of pyoderma gangrenosum-like ulcers in patients with X-linked agammaglobulinemia is of great importance for the early initiation of appropriate and curative antibiotic therapy.

2011-10-01

The dose of 2% chlorhexidine acetate (2CA; Nolvasan(®) Surgical Scrub; Fort Dodge Animal Health, Fort Dodge, IA, USA) for canine superficial pyoderma was evaluated. The first trial compared three doses (group 1, 57 mL/m(2) body surface area; group 2, 29 mL/m(2) body surface area; and group 3, 19 mL/m(2) body surface area) in a randomized, double-blind, controlled fashion. Twenty-seven dogs with superficial pyoderma were treated with 2CA at the allocated doses every 2 days for 1 week. The owners and investigators subjectively evaluated the dogs, and investigators scored skin lesions, including erythema, papules/pustules, alopecia and scales, on a 0-4 scale. There were no significant differences in response between the treatment groups. The second trial established a practical dose-measuring method for 2CA. Sixty-eight owners were asked to apply 2CA on their palm in an amount corresponding to a Japanese ¥500 coin, 26.5 mm in diameter. This yielded an average dose of 0.90±0.40 mL. Mathematically, the doses used in groups 1, 2 and 3 can be represented as one coin per approximately one-, two- and three-hand-sized lesions, respectively. The results therefore suggest that owners instructed to apply one coin of the product per two-hand-sized areas of superficial pyoderma would use the range of doses evaluated in this trial. © 2011 The Authors.

Pyoderma gangrenosum (PG) is an uncommon ulcerative disease of the skin. The cause is unknown but the condition is often associated with other diseases such as rheumatoid arthritis, ulcerative colitis, Crohn's disease or monoclonal gammopathy. The association between PG and haematological malignancies (acute leukaemia, Myeloproliferative disorders) is infrequent. Two cases of PG associated with haemopathy are described; one had primary thrombocythaemia and the other, acute myeloblastic leukaemia following for myeloma. The significance of this association is discussed in the light of other observations previously reported in the literature.

Superficial pyoderma is traditionally considered rare in cats but may be more prevalent than previously reported. To better characterize superficial pyoderma in cats. Fifty-two cats from a dermatology referral population over a 10 year period. This study was retrospective. Cases were included if neutrophils and intracellular bacteria were reported from surface cytology of skin lesions. Medical records were reviewed for signalment, historical and clinical data, cytology results, primary skin diagnoses and treatment details. Disease prevalence was 20%, with no breed or sex predispositions. The estimated median age of onset was 2 years, affecting 54% of cats by 3 years and 23% after 9 years. Fewer cases presented during winter (15%) compared with other seasons. Skin lesions were typically multifocal, affecting the face (62%), neck (37%), limbs (33%) and ventral abdomen (29%) most commonly. Crusting (83%), alopecia (67%), ulceration/erosion (54%) and erythema (46%) were common lesion types. Pruritus was reported in 92% of cats. Underlying hypersensitivities (confirmed in 60%; suspected in 19%), and atopic dermatitis specifically (confirmed in 48%), were the most frequent primary dermatoses. Cats were treated with a variety of systemic and/or topical antimicrobials. The overall apparent response was considered good in 61% and poor in 27% of cats. Recurrence was confirmed or suspected in 42% of cats. Feline superficial pyoderma was more prevalent in this study population than previously reported. Young cats with hypersensitivities and older cats were more commonly affected, and a variety of lesion types and distributions occurred. © 2012 The Authors.

Perianal pyoderma (hidradenitis suppurativa-acne conglobata) is a chronic disease which in its progressive form cannot be treated by conservative methods. Extensive suppurative foci must be radically excised incl. all systems of fistulas right down to the fascia and the defects which develop are allowed to heal per secundam or after several weeks they can at a different period of time be covered by a skin transplant. The authors present their 30-year experience with surgical treatment of 39 patients. Treatment was in all instances successful after radical surgical excision. All these patients have fully recovered as regards work capacity as well as social aspects.

A case of cytomegalovirus colitis following immunosuppressive treatment for pyoderma gangrenosum.

2005-04-01

We report a case of pyoderma gangrenosum (PG) complicated by cytomegalovirus (CMV)-induced colitis. A 79-year-old woman with PG was treated with corticosteroid and cyclosporin. She had blood in her stool and advancing anemia during the treatment. A colonoscopic biopsy specimen from the colon revealed typical CMV-infected cells with CMV inclusions confirmed by immunohistochemistry. Furthermore, there were many CMV-antigen-positive leukocytes, suggesting an active CMV infection, which is serious in compromised hosts. Although ulcerative colitis and Crohn's disease are well known as complications of PG, CMV enterocolitis should be considered in the differential diagnosis of enterocolitis in immunocompromised patients.

Staphylococcus pseudintermedius and Staphylococcus schleiferi Subspecies coagulans from Canine Pyoderma Cases in Grenada, West Indies, and Their Susceptibility to Beta-Lactam Drugs

Over a 2-year period 66 cases of canine pyoderma in Grenada, West Indies, were examined by aerobic culture in order to ascertain the bacteria involved and their antimicrobial resistance patterns. Of the 116 total bacterial isolates obtained, the majority belonged to Gram-positive species, and the most common organism identified through biochemical and molecular methods was Staphylococcus pseudintermedius. Additionally, identification of a Staphylococcus schleiferi subspecies coagulans isolate was confirmed by molecular methods. All isolates of staphylococci were susceptible to beta-lactam drugs: amoxicillin-clavulanic acid, cefovecin, cefoxitin, cefpodoxime, and cephalothin. They were also susceptible to chloramphenicol and enrofloxacin. Resistance was highest to tetracycline. Methicillin resistance was not detected in any isolate of S. pseudintermedius or in S. schleiferi. Among the Gram-negative bacteria, the most common species was Klebsiella pneumoniae, followed by Acinetobacter baumannii/calcoaceticus. The only drug to which all Gram-negative isolates were susceptible was enrofloxacin. This report is the first to confirm the presence of S. pseudintermedius and S. schleiferi subspecies coagulans, in dogs with pyoderma in Grenada, and the susceptibility of staphylococcal isolates to the majority of beta-lactam drugs used in veterinary practice.

The clinical and antibacterial efficacy of two shampoos used as a sole antibacterial treatment in dogs with superficial pyoderma were investigated and compared. In a randomised, partially blinded study, a 3 per cent chlorhexidine gluconate shampoo (Chlorhex 3; Leo Animal Health) was compared against a 2.5 per cent benzoyl peroxide shampoo (Paxcutol; Virbac) in 22 dogs with superficial pyoderma. Dogs were washed two to three times weekly with a 10-minute contact time over 21 days. Clinical scores and bacterial counts were assessed on days 1, 8 and 22 and compared within and between treatment groups; overall response was assessed at the end of the study. Twenty dogs completed the study; 15 (68.2 per cent) showed an overall clinical improvement and the clinical signs resolved in three chlorhexidine-treated dogs. In the chlorhexidine-treated group, scores for papules/pustules (P<0.001), investigator-assessed pruritus (P=0.003), total bacterial counts (P=0.003) and counts for coagulase-positive staphylococci (P=0.003) were reduced after three weeks. Scores and bacterial counts did not vary significantly in the benzoyl peroxide-treated group.

High-grade evidence is lacking for most therapeutic decisions in Crohn's disease. Appropriateness criteria were developed for upper gastro-intestinal, extra-intestinal manifestations and drug safety during conception, pregnancy and breastfeeding in patients with Crohn's disease, to assist the physician in clinical decision making. The European Panel on the Appropriateness of Crohn's Disease Therapy (EPACT II), a multidisciplinary international European expert panel, rated clinical scenarios based on evidence from the published literature and panelists' own clinical expertise. Median ratings (on a 9-point scale) were stratified into three categories: appropriate (7-9), uncertain (4-6 with or without disagreement) and inappropriate (1-3). Experts were also asked to rank appropriate medications by priority. Proton pump inhibitors, steroids, azathioprine/6-mercaptopurine and infliximab are appropriate for upper gastro-duodenal Crohn's disease; for stenosis, endoscopic balloon dilation is the first-line therapy, although surgery is also appropriate. Ursodeoxycholic acid is the only appropriate treatment for primary sclerosing cholangitis. Infliximab is appropriate for Pyoderma gangrenosum, ankylosing spondylitis and uveitis, steroids for Pyoderma gangrenosum and ankylosing spondylitis, adalimumab for Pyoderma gangrenosum and ankylosing spondylitis, cyclosporine-A/tacrolimus for Pyoderma gangrenosum. Mesalamine, sulfasalazine, prednisone, azathioprine/6-mercaptopurine, ciprofloxacin, and probiotics, may be administered safely during pregnancy or for patients wishing to conceive, with the exception that male patients considering conception should avoid sulfasalazine. Metronidazol is considered safe in the 2nd and 3rd trimesters whereas infliximab is rated safe in the 1st trimester but uncertain in the 2nd and 3rd trimesters. Methotrexate is always contraindicated at conception, during pregnancy or during breastfeeding, due to its known teratogenicity. Mesalamine, prednisone, probiotics and infliximab are considered safe during breastfeeding. EPACT II recommendations are freely available online (www.epact.ch). The validity of these criteria should now be tested by prospective evaluation.

A 36-year-old woman was admitted to our hospital due to swelling and redness of the left lateral malleolus and dorsum of the left foot with severe pain, with a flare-up of ulcerative colitis (UC). A pathologic examination by skin biopsy led to a diagnosis of pyoderma gangrenosum (PG). She was treated with the intravenous administration of prednisolone (60 mg/day), and granulocyte and monocyte adsorption apheresis (GMA) was performed twice-a-week for 5 weeks. This treatment dramatically improved both the skin and colonic mucosal lesions. These results suggest that a combination of GMA and corticosteroids might be recommendable to induce the remission of serious PG complicated with UC.

Clinical features and treatment of peristomal pyoderma gangrenosum.

Peristomal pyoderma gangrenosum (PPG), an unusual variant of pyoderma gangrenosum, has been reported almost exclusively in patients with inflammatory bowel disease (IBD) and is frequently misdiagnosed. To better characterize the clinical manifestations, diagnosis, and management of PPG. Retrospective analysis of 7 patients with PPG observed in a university-affiliated community setting between 1988 and December 1999. Clinical and histopathologic features, associated disorders, and microbiologic findings. Two patients had Crohn disease, 2 had ulcerative colitis, and 3 had abdominal cancer. Five patients had at least 1 relapse of PPG after initial healing. Although 3 of 4 patients with IBD had active bowel disease, a parallel course with PPG occurred in only 1 patient. Both patients whose stoma was relocated developed an ulcer at the new site. Effective therapies included topical superpotent corticosteroids; intralesional injection of triamcinolone acetonide at the ulcer margin; topical cromolyn sodium; oral dapsone, prednisone, cyclosporine, mycophenolate mofetil; and intravenous infliximab. Our experiences demonstrate that although PPG has been most often reported in patients with IBD, it may occur in the absence of IBD. Biopsy of the skin lesion is not diagnostic but excludes other causes. Relocation of the stoma may be associated with a new ulceration and should be avoided. Trauma to the skin of a predisposed patient may elicit the pustules or ulcerations associated with pathergy. JAMA. 2000;284:1546-1548.

Pyoderma gangrenosum (PG) manifests as recurrent deep ulceration of the skin and PG is associated with a variety of disorders. Approximately 30% of the cases of PG develop in patients with inflammatory bowel disease. A 34-year-old woman presented with a one-week history of recurrent ulcers on the right cheek and back. She was diagnosed with ulcerative colitis (UC) 4 years previously and with PG 1 year previously. The clinical course of the skin lesions followed the status of her UC. The patient's skin lesions and bowel symptoms were not improved with prednisolone. After she was started on mesalazine, we observed rapid resolution of skin lesions and bowel symptoms. Herein, we report a case of recurrent PG with UC, and we discuss the possible association between these two conditions, and the efficacy of mesalazine therapy for the treatment of PG combined with UC.

2016-10-01

Pyoderma gangrenosum (PG) is an uncommon extra-intestinal manifestation of inflammatory bowel disease (IBD). Despite limited published literature, biologics have caused a paradigm shift in the management of this difficult-to-treat skin condition. The clinical data and outcomes of three patients with active ulcerative colitis and concurrent PG treated with biologics (infliximab two and adalimumab one) are reviewed in this report. Biologics were added because of the sub-optimal response of the colonic symptoms and skin lesions to parenteral hydrocortisone therapy. All three patients showed a dramatic response to the addition of the biologics. In view of the rapid healing of the skin lesions, superior response rate, and the additional benefit of improvement in the underlying colonic disease following treatment, anti-tumor necrosis factor blockers should be considered as a first line therapy in the management of PG with underlying IBD.

2015-08-01

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.

Diseases associated with hidranitis suppurativa: part 2 of a series on hidradenitis.

PubMed

Scheinfeld, Noah

2013-06-15

Hidradenitis suppurativa (HS), a pathologic follicular disease, impacts patients' lives profoundly and usually occurs in isolation. The diseases with the strongest association are obesity, depression, and pain. HS is associated with many diseases including acne conglobata (AC), dissecting cellulitis, pilonidal cysts, and obesity. Pyoderma fistulans sinifica (fox den disease) appears to be the same entity as Hurley Stage 2 of 3 HS. The rate of acne vulgaris in HS patients mirrors unaffected controls. The most common, albeit still uncommon, association is with seronegative, haplotype unlinked arthritis (most importantly B27), in particular spondolyarthritis. Crohn disease and HS occur together at a rate that varies from 0.6% to 38% in retrospective cases series. Ulcerative colitis occurred with HS in 14% of patients in one series. The next most common association is with pyoderma gangrenosum, but this association is likely under-reported. Synovitis-Acne-Pustulosis Hyperostosis-Osteitis (SAPHO) syndrome, which is rare, has more than 10 reports linking it to HS. Nine case reports have linked Dowling-Degos disease (DDD) to HS and two reports related HS to Fox-Fordyce disease (FF), but because both occur in the axilla this might be a mere coincidence. HS is rarely associated with ophthalmic pathology. Specifically, more than 5 reports link it to Keratitis-Ichthyosis-Deafness syndrome (KID); greater than10 cases link it to interstitial keratitis and 2 cases are linked to Behçet's disease. The presence of proteinuria and acute nephritis link HS to the kidney, especially since and reports have documented resolution of HS after renal transplant. Florid steatocystoma multiplex, Sjogren Syndrome, and HS have been linked and their reports likely underestimate their coincidence because all these entities involve occlusion (albeit by different mechanisms). Three reports link HS and amyloid, but both share some common genetic underpinnings and thus the coincidence of these diseases is likely underreported. Pyoderma vegetans has been noted in 2 cases of HS and 4 cases of Inflammatory Bowel Disease (IBD) and is likely a clue to the linkage of the pathology of IBD and HS. Pityriasis rubra pilaris, in particular Type VI related to HIV, has a relationship more commonly with acne conglobata, but with HS also. Single case reports of diseases associated with HS include systemic lupus erythematosus, acromegaly, Down syndrome, Bazex-Dupre´-Christol, and prurtis ani, but these might be coincidences. Pyogenic Arthritis, Pyoderma gangrenosum, and Acne (PAPA Syndrome) and Pyoderma gangrenosum, Acne, and Suppurative Hidradenitis (PASH Syndrome) are pyodermic-arthritic syndromes that are associated with HS. Erythema nodosum and granulomatous lobular mastitis have been reported with HS but the significance of these reports is uncertain. Because of scarring, HS can result in lymphedema including scrotal elephantiasis and verrucous lymphedema. HS is sometimes accompanied by obesity, hypertension, and anemia and can be considered a disease in the spectrum of metabolic syndrome, a skin disease with systemic consequences. HS, like other types of chronic inflammation when long standing in the perianal and perineal areas, can result in squamous cell cancer. A variety of drugs can induce HS. These include lithium, sirolimus, cyclosporine, vemurafenib, and oral contraceptives. Inverse psoriasis or psoriasis vulgaris as a side effect of infliximab therapy may be associated with HS. These associations aside, most cases of HS occur in isolation without coincident morbidity.

The immunobiology underlying the slow acquisition of skin immunity to group A streptococci (GAS), is not understood, but attributed to specific virulence factors impeding innate immunity and significant antigenic diversity of the type-specific M-protein, hindering acquired immunity. We used a number of epidemiologically distinct GAS strains to model the development of acquired immunity. We show that infection leads to antibody responses to the serotype-specific determinants on the M-protein and profound protective immunity; however, memory B cells do not develop and immunity is rapidly lost. Furthermore, antibodies do not develop to a conserved M-protein epitope that is able to induce immunity following vaccination. However, if re-infected with the same strain within three weeks, enduring immunity and memory B-cells (MBCs) to type-specific epitopes do develop. Such MBCs can adoptively transfer protection to naïve recipients. Thus, highly protective M-protein-specific MBCs may never develop following a single episode of pyoderma, contributing to the slow acquisition of immunity and to streptococcal endemicity in at-risk populations.

Pyoderma gangrenosum: an exceptional complication of venous access device.

PubMed

La Marca, Sophie; Toussoun, Gilles; Ho Quoc, Christophe; Sebban, Henry; Delay, Emmanuel

2014-01-01

Pyoderma gangrenosum (PG) is a rare disease whose precise etiology remains unknown. It causes rapidly developing skin necrosis and can occur after surgery, or after a nonspecific external stimulus. This condition is difficult to diagnose because it often mimics a fulminant infection. We present a case of very significant local presentation of PG after placement of a venous access device. Fifteen days after placement, the patient developed extensive cutaneous ulcers and necrosis in the subclavicular area, which led to the misdiagnosis of infection. The device was removed and the patient was given antibiotics. Because there was no improvement following antibiotic treatment, combined with the worrying and extensive appearance of the skin and extremely intense pain, the diagnosis of PG was made. The patient was immediately treated with high-dose corticosteroids, resulting in rapid improvement of the lesions and relief of pain. PG should be considered in cases of extensive, antibiotic-resistant ulceration and treatment with corticosteroids should be initiated. Clinical improvement is usually dramatic, with almost immediate suppression of the pain and arrest of the lesion's progression. Early treatment is the best guarantee for an effective recovery.

Localization of immunoglobulins and complement by the peroxidase antiperoxidase method in autoimmune and non-autoimmune canine dermatopathies.

1987-01-01

Formalin-fixed, paraffin embedded skin biopsy specimens from 44 dogs with various dermatopathies were examined for the presence of immunoglobulins (IgG, IgM, IgA) and complement (C3) by the peroxidase antiperoxidase method (PAP). Final diagnoses of the skin diseases were determined by clinical findings, fungal and bacterial cultures, skin scrapings, serum endocrinologic tests, and histologic features of cutaneous biopsies. The dermatopathies included examples of pyoderma (folliculitis/furunculosis), demodecosis, sarcoptic mange, dermatophytosis, endocrine dermatopathy, and autoimmune skin disease (AISD). In the latter category, 7 cases of pemphigus foliaceus, 1 pemphigus vulgaris, 4 discoid lupus erythematosus (DLE) and 4 examples of indeterminate AISD were examined. Immunoglobulins, C3, or both, were localized in tissue sections from AISD (15/16), pyoderma (7/11), demodecosis (4/8) sarcoptic mange (3/3), and dermatomycosis (2/3). Endocrine dermatopathy biopsies were consistently negative for Ig and C3 (0/3). The pattern of localization was most often intercellular (31/44 positive biopsies) with basement membrane immunoreactivity in 4 cases of DLE, and 1 case of indeterminate AISD. There was no consistent correlation between histologic features of hematoxylin and eosin-stained biopsies and the presence of Ig and C3. Clinical outcome was similar in both Ig and C3 positive and negative cases of non-AISD dermatitis. The high percentage (95%) of positive results in AISD biopsies indicates the usefulness and sensitivity of the PAP method for the localization of Ig and C3. Because of the high percentage of Ig localization in pyoderma (73%), biopsy specimens with extensive inflammatory skin disease are not suitable for diagnosis of AISD. The PAP method is useful in the diagnosis of AISD in biopsy specimens with minimal inflammation. Caution is warranted in the interpretation of immunoreactivity independent of clinical and histologic information.

Epidemiology of scabies.

Scabies is a common skin infestation globally, particularly in the developing world. With the launch of the International Alliance for the Control of Scabies (IACS) in 2012, this review aims to present the recent evidence of the current epidemiological situation for scabies across the globe. Mindful of the fact that the downstream complications of scabies infestations, pyoderma, streptococcal glomerulonephritis and subsequent chronic renal impairment and rheumatic fever, have been recognized as being more significant to global health than previously acknowledged, the review focusses also on the epidemiological evidence from developing countries. Scabies occurrence rates vary in the recent literature from 2.71 per 1000 to 46%. Although it is responsible for larger disease burdens and complications such as pyoderma and renal and heart disease in the tropics, scabies outbreaks in the developed world amongst vulnerable communities and health institutions contribute a significant cost to the health services managing them. Scabies remains common across the world, but is such a health issue in the developing world that the suggestion that it be considered a neglected tropical disease is a pertinent one. Standardized diagnostic criteria and even a point-of-care diagnostic test would be a major contribution to the understanding of this epidemic.

Cross-sectional survey on the use and impact of the Danish national antibiotic use guidelines for companion animal practice.

The Danish antibiotic use guidelines for companion animal practice were published by the Danish Veterinary Association in 2012. Since then, national surveillance data indicate a 10% reduction in the total use of antibiotics for companion animals, particularly a marked reduction in the use of third generation cephalosporins. The aim of the study was to assess if and how the guidelines have impacted diagnostic and antibiotic prescription habits of the users, and to identify user perceived barriers to implementation. An online questionnaire was sent to all 882 members of the Danish Small Animal Veterinary Association in October 2015. The survey was completed by 151 veterinarians. Respondents most frequently consulted the recommendations on skin and urinary tract infections (UTI), and users generally reported a high degree of adherence to the recommendations. Sixty-five per cent indicated that the guidelines had influenced their habits in one or more of the areas being investigated, i.e. perioperative use of antibiotics, use of first line antibiotics for the treatment of pyoderma or UTI, and/or use of microbiological diagnostics. Perioperative use of antibiotics for clean surgeries was uncommon, irrespective of whether respondents had consulted the relevant recommendations or not. On the contrary, significant differences in the prescribing habits between guideline users and non-users were observed for pyoderma and UTI, suggesting an impact of the guidelines towards more prudent antimicrobial use. The diagnostic habits were examined in a subgroup of 63 guideline users. Of those, 19 and 39% reported frequent use of culture and susceptibility (C&S) testing prior to treating pyoderma and UTI respectively, whereas 68-84% reported C&S testing in the event of poor response to treatment or recurrence of infections. The main barriers for implementation of therapeutic recommendations were confidence in old prescribing practices and unavailability of recommended drugs. The main barriers for C&S testing were good experience with empiric treatment, and the owners' financial situation. The findings suggest a positive influence of the national antibiotic guidelines on prescription patterns among companion animal practitioners in Denmark. Sustained campaign activity is encouraged and should include promotion of bacteriological testing.

Questionnaire survey of detrimental fur animal epidemic necrotic pyoderma in Finland.

In 2007, a previously unrecorded disease, fur animal epidemic necrotic pyoderma (FENP), was detected in farmed mink (Neovision vision), foxes (Vulpes lagopus) and Finnraccoons (Nyctereutes procyonoides) in Finland. Symptoms included severe pyoderma with increased mortality, causing both animal welfare problems and economic losses. In 2011, an epidemiologic questionnaire was mailed to all members of the Finnish Fur Breeders' Association to assess the occurrence of FENP from 2009 through the first 6 months of 2011. The aim was to describe the geographical distribution and detailed clinical signs of FENP, as well as sources of infection and potential risk factors for the disease. A total of 239 farmers (25%) returned the questionnaire. Clinical signs of FENP were observed in 40% (95% CI 34-46%) of the study farms. In addition, the survey clarified the specific clinical signs for different animal species. The presence of disease was associated with the importation of mink, especially from Denmark (OR 9.3, 95% CI 2.6-33.0). The transmission route between Finnish farms was associated with fur animal purchases. Some risk factors such as the farm type were also indicated. As such, FENP was detected more commonly on farms with more than one species of fur animal in comparison to farms with, for example, only foxes (OR 4.6, 95% CI 2.4-8.6), and the incidence was higher on farms with over 750 breeder mink compared to smaller farms (OR 3.8, 95% CI 1.6-9.0). Contact between fur animals and birds and other wildlife increased the risk of FENP on farms. Responses also indicated that blocking the entry of wildlife to the animal premises protected against FENP. FENP was most likely introduced to Finland by imported mink and spread further within the country via domestically purchased fur animals. Some potential risk factors, such as the type and size of the farm and contact with wildlife, contributed to the spread of FENP. Escape-proof shelter buildings block the entry of wildlife, thus protecting fur animals against FENP.

We here describe an unusual case of a 33-year-old-caucasian male with ulcerative colitis and skin lesions diagnosed as leukocytoclastic vasculitis. An initial treatment with oral deflazacort led to little benefit, while treatment with oral mesalazine caused remission of the skin and intestinal manifestations in 2 weeks.

A number of cutaneous changes are known to occur in the course of inflammatory bowel diseases (IBD), including pyoderma gangrenosum, erythema nodosum, perianal disease, erythematous eruptions, urticaria, and purpura. However, occurrence of skin manifestations prior to the development of ulcerative colitis is a rare occasion. Here, we report a case of ulcerative colitis associated with leukocytoclastic vasculitis in which the intestinal symptoms became overt 8 mo after the development of skin lesions.

Objective To determine whether ciclosporin is superior to prednisolone for the treatment of pyoderma gangrenosum, a painful, ulcerating skin disease with a poor evidence base for management. Design Multicentre, parallel group, observer blind, randomised controlled trial. Setting 39 UK hospitals, recruiting from June 2009 to November 2012. Participants 121 patients (73 women, mean age 54 years) with clinician diagnosed pyoderma gangrenosum. Clinical diagnosis was revised in nine participants after randomisation, leaving 112 participants in the analysis set (59 ciclosporin; 53 prednisolone). Intervention Oral prednisolone 0.75 mg/kg/day compared with ciclosporin 4 mg/kg/day, to a maximum dose of 75 and 400 mg/day, respectively. Main outcome measures The primary outcome was speed of healing over six weeks, captured using digital images and assessed by blinded investigators. Secondary outcomes were time to healing, global treatment response, resolution of inflammation, self reported pain, quality of life, number of treatment failures, adverse reactions, and time to recurrence. Outcomes were assessed at baseline and six weeks and when the ulcer had healed (to a maximum of six months). Results Of the 112 participants, 108 had complete primary outcome data at baseline and six weeks (57 ciclosporin; 51 prednisolone). Groups were balanced at baseline. The mean (SD) speed of healing at six weeks was −0.21 (1.00) cm2/day in the ciclosporin group compared with −0.14 (0.42) cm2/day in the prednisolone group. The adjusted mean difference showed no between group difference (0.003 cm2/day, 95% confidence interval −0.20 to 0.21; P=0.97). By six months, ulcers had healed in 28/59 (47%) participants in the ciclosporin group compared with 25/53 (47%) in the prednisolone group. In those with healed ulcers, eight (30%) receiving ciclosporin and seven (28%) receiving prednisolone had a recurrence. Adverse reactions were similar for the two groups (68% ciclosporin and 66% prednisolone), but serious adverse reactions, especially infections, were more common in the prednisolone group. Conclusion Prednisolone and ciclosporin did not differ across a range of objective and patient reported outcomes. Treatment decisions for individual patients may be guided by the different side effect profiles of the two drugs and patient preference. Trial registration Current Controlled Trials ISRCTN35898459.

Topical Medical Cannabis: A New Treatment for Wound Pain-Three Cases of Pyoderma Gangrenosum.

PubMed

Maida, Vincent; Corban, Jason

2017-11-01

Pain associated with integumentary wounds is highly prevalent, yet it remains an area of significant unmet need within health care. Currently, systemically administered opioids are the mainstay of treatment. However, recent publications are casting opioids in a negative light given their high side effect profile, inhibition of wound healing, and association with accidental overdose, incidents that are frequently fatal. Thus, novel analgesic strategies for wound-related pain need to be investigated. The ideal methods of pain relief for wound patients are modalities that are topical, lack systemic side effects, noninvasive, self-administered, and display rapid onset of analgesia. Extracts derived from the cannabis plant have been applied to wounds for thousands of years. The discovery of the human endocannabinoid system and its dominant presence throughout the integumentary system provides a valid and logical scientific platform to consider the use of topical cannabinoids for wounds. We are reporting a prospective case series of three patients with pyoderma gangrenosum that were treated with topical medical cannabis compounded in nongenetically modified organic sunflower oil. Clinically significant analgesia that was associated with reduced opioid utilization was noted in all three cases. Topical medical cannabis has the potential to improve pain management in patients suffering from wounds of all classes. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

Das Pyoderma gangraenosum (PG) ist eine seltene, inflammatorische destruktiv-ulzerierende neutrophile Erkrankung mit weitgehend unklarer Pathophysiologie. In dieser Studie wurden die potenziell relevanten Kofaktoren und Begleiterkrankungen von Patienten mit PG aus drei dermatologischen Wundzentren in Deutschland differenziert ausgewertet. Von den insgesamt 121 analysierten Patienten waren Frauen (66,9 %) häufiger betroffen als Männer. Das Alter der Patienten war 18-96 Jahre (Mittelwert [MW]: 59,8); die Wunden hatten eine Größe von 1-600 cm² (MW: 65,6 cm²) und waren überwiegend sehr schmerzhaft (VAS 1-10, MW: 7). Die Unterschenkel waren am häufigsten (71,9 %) betroffen. Bei 12 (9,9 %) Patienten bestanden chronisch entzündliche Darmerkrankungen (5,8 % Colitis ulcerosa; 4,1 % Morbus Crohn), bei 14,1 % der Patienten wurde eine Begleiterkrankung aus dem rheumatischen Formenkreis beschrieben. Neoplasien bestanden bei 20,6 % der Patienten, von denen 6,6 % als hämatologische und 14,1 % als solide Neoplasien klassifiziert wurden. Aus dem Kreis des metabolischen Syndroms wurde bei 69,4 % Patienten eine Adipositas, bei 57,9 % eine arterielle Hypertonie und bei 33,9 % ein Diabetes mellitus diagnostiziert. Diese Datenanalyse bestätigt Assoziationen des PG mit dem metabolischen Syndrom und mit Neoplasien, die zukünftig frühzeitig bei einer zielgerichteten Diagnostik der Patienten beachtet und behandelt werden sollten. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

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.

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) and Sweet's Syndrome (SS) are inflammatory skin diseases caused by the accumulation of neutrophils in the skin and, rarely, in internal organs. These neutrophilic dermatosis (NDs) are distinguished by the existence of forms of transition or overlap. They are frequently associated to systemic diseases especially hematologic and gastrointestinal ones. We report a case of a patient with ulcerative colitis (UC) who successively developed two types of NDs: PG then SS. A 66 years old patient with a history of UC consulted in July 2012 for an erythematous swelling of the back of the right hand treated with antibiotics without improvement. At that time, bacteriological samples were negative. In October 2012, he was hospitalized for polyarthralgia and impaired general condition. In physical examination, he had vesiculobullous plaque of 10 cm long of the right hand and wrist, infiltrated erythematous plaque on the right leg and another topped with a large pustule at the left ankle. Skin biopsy showed at the back of the right hand an aspect of PG and at the infiltrated plaques of the ankle an aspect of SS. Prednisone was started with improvement of the skin lesions and a recovery condition. The combination of PG and SS has already been described in cases of hematologic malignancy and rarely in UC. There is also the notion of passage from a neutrophilic dermatosis to another. Indeed, a typical lesion initially of SS can evolve to a future PG. This case demonstrates that neutrophilic dermatoses form a continous spectrum of entities that may occur in UC.

To investigate the cutaneous manifestations in patients with ulcerative colitis (UC) and related factors. Patients admitted to Department of Gastroenterology Peking University First Hospital from January 1994 to December 2014 and diagnosed as UC were retrospectively enrolled in this study. Skin disorders were confirmed by the dermatologists. Clinical data were collected and compared between patients with and without cutaneous manifestations. Among the total 373 UC patients, there were 34 cases (9.1%) with cutaneous manifestations, including 11 pyoderma gangrenosum, 8 erythema nodosum, 6 eczema, 3 psoriasis, 2 pemphigus, 1 granulomatous cheilitis, 1 ichthyosis, 1 acne rosacea, and 1 impetigo. The skin manifestations may occur after the diagnosis, simultaneously or even before the diagnosis of UC, which were 24, 7 and 3 patients respectively. The mean age in patients with skin lesions was (47.2±12.1) years, male to female ratio 0.79∶1. More patients with skin manifestations had severe activity of UC compared with non-skin group [50.0%(17/34) vs 25.1%(85/339), P=0.01]. In addition, the proportion of extensive colitis in skin lesion group was significantly higher than that in non-skin group [76.5%(26/34) vs 54.6%(185/339), P=0.04]. The cutaneous manifestations associated with UC are polymorphic, erythema nodosums and pyoderma gangrenosums are the most common skin lesions seen in UC patients. Skin lesions occur concurrently, pre or post the diagnosis of UC. Skin lesions in UC patients suggest more severe disease activity. Clinicians need to pay more attention to this group.

Topical antimicrobial treatment for canine pyoderma is becoming increasingly important, but little is known about the mechanism of action and persistence of activity of antimicrobial shampoos. To determine the residual antimicrobial activity on canine hairs treated with antimicrobial shampoos. Forty-two dogs from a research institution. Dogs were treated with six different shampoos and the combination of one shampoo and conditioner containing benzoyl peroxide, chlorhexidine in different concentrations (0.8, 2, 3 and 4%), ethyl lactate and miconazole twice weekly for 2 weeks. A shampoo vehicle without antimicrobial ingredients was used as the control. Hairs were collected immediately after and 2, 4 and 7 days after the last shampoo therapy and placed onto an agar plate streaked with Staphylococcus pseudintermedius. After incubation, the growth inhibition zone around the hair shafts was measured. The largest zone of inhibition of bacterial growth was seen after shampoos containing 2 and 3% chlorhexidine and the combination of chlorhexidine shampoo and conditioner. The zone of inhibition was smaller with the shampoos containing 0.8 and 4% chlorhexidine. There was no difference between the inhibition zones post-treatment with benzoyl peroxide, ethyl lactate and control. The efficacy of a shampoo is dependent not only on the concentration of the active ingredients but also on the shampoo formulation. Hair shafts treated with shampoos containing 2 and 3% chlorhexidine and the combination of shampoo and conditioner inhibited bacterial growth significantly and seem suitable to treat canine bacterial pyoderma. © 2013 The Authors.

In 100 dogs with 4 inflammatory dermatologic diseases, buffy coat preparations from EDTA-treated blood samples were examined cytologically. Fifty-four dogs had atopy, 26 had flea-bite hypersensitivity, 17 had sarcoptic mange, and 3 had food allergy. Twenty-eight dogs had 2 or more concurrent skin diseases; most of these had secondary pyoderma. Dogs did not have mast cell tumors. Thirteen samples contained 1 or more mast cells/4 slides reviewed. This study revealed that dogs with inflammatory skin diseases can have a few to many mast cells evident on cytologic examination of buffy coat preparations.

The prevalence of common skin infections in four districts in Timor-Leste: a cross sectional survey

PubMed Central

2010-01-01

Background Skin infections are a common public health problem in developing countries; however, they are rarely managed using a population based approach. Recent data on the burden of skin infections in Timor-Leste are limited. Our survey appears to be the only widespread survey conducted in more than 30 years and was designed to determine the baseline prevalence of some common skin infections in Timor-Leste. Methods We conducted a cross sectional survey in 14 sites including community health clinics, schools and hospitals within four different geographical regions. Participants were examined for five conditions (scabies, pyoderma, fungal infections, leprosy and yaws) by a multidisciplinary team. Analyses were conducted using EpiInfo version 6.04d. Results We examined the skin of 1535 participants aged between four months and 97 years. The majority of participants were male, aged between 11 and 20 years and had at least one condition of interest (56.0%, 56.0%, and 63.1%, respectively). Fungal infections were the most common presentation (39.0%) and males were more commonly affected than females (42.3% vs 34.0%, respectively, pvalue < 0.0001). Among those people with more than one condition the two most common co-infections were scabies with either pyoderma or a fungal infection (38.0% and 32.0%, respectively). The survey identified 29 previously undiagnosed cases of leprosy and six cases of yaws. Conclusions Our findings indicate the need for a comprehensive programme to address these conditions. There are successful disease control programmes in place within the country and it is hoped a healthy skin programme could be integrated into an established disease control programme in order to maximise health benefits and resources.

Topical tacrolimus for parastomal pyoderma gangrenosum: a report of two cases.

PubMed

Altieri, Maria; Vaziri, Khashayar; Orkin, Bruce A

2010-09-01

Pyoderma gangrenosum (PG) is an idiopathic, ulcerative, inflammatory dermatologic condition that occurs in patients with systemic diseases such as inflammatory bowel disease (IBD). This inflammatory skin disorder is presumably caused by an autoimmune mechanism and the diagnosis is one of exclusion. PG is not a common condition but it is thought to account for approximately 50% of chronic parastomal ulcers. Refractory parastomal PG (PPG) occurs in patients with inactive disease or after bowel resection. Multiple medical treatments, ranging from topical agents for mild disease to systemic immunosuppressive therapy for severe disease, have been used with varying rates of success. Using topical tacrolimus, an immunosuppressant that inhibits T-lymphocyte proliferation, and meticulous stoma care can result in successful treatment. Two women (ages 59 and 62 years) with a history of ulcerative colitis and colon resection presented with parastomal ulcers consistent with PPG. The 59-year patient presented with a painful 2 cm x 2 cm parastomal ulcer that improved following daily application of topical tacrolimus 0.1%. The 62-year old woman first was prescribed daily appliance changes and application of topical triamcinolone 0.5% to her 3-cm ulcer. The ulcer increased in size and treatment was changed to daily application of tacrolimus 0.1%. After 2 months and a reduction in ulcer size and severity, the dosage was changed to daily application of tacrolimus 0.03%. Both patients reported resolution of pain and itching, the most common symptoms of PPG, and no adverse effects were observed. The encouraging results observed in these two cases confirm that tacrolimus helps resolve PPG lesions even at concentrations previously thought to be ineffective. Additional studies to help clinicians optimize care of these painful lesions are needed.

Risk factors for peristomal pyoderma gangrenosum (PPG) are not well defined. The aim of this study was to evaluate risk factors associated with development of PPG. Both PPG patients and controls were obtained by searching a database of the Cleveland Clinic using the ICD-9 code from March 2005 to May 2011. The control group was selected by matching for underlying diseases and type of stoma in a ratio of 3:1. Univariate and multivariate analyses were performed. A total of 15 PPG cases and 45 controls were included. The mean age at the time of PPG diagnosis was 46.0 ± 14.4 years. The underlying disease was Crohn's disease in 7 patients (46.7%), ulcerative colitis in 7 (46.7%) and indeterminate colitis in 1 (6.7%). Eleven patients (73.3%) had end ileostomy, 3 (20.0%) had loop ileostomy and 1 (6.7%) had colostomy. Eleven patients (73.3%) had active intestinal disease. In multivariate analysis, female gender, the presence of concurrent autoimmune disorders, and a high body mass index (BMI) were significantly associated with the presence of PPG, with odds ratios of 8.385 (95% confidence interval [CI]: 1.496-46.982, p=0.015), 6.882 (95% CI:1.438-32.941, p=0.016), and 9.895 (95% CI: 1.970-43.704, p=0.005), respectively. After a median follow-up of 12.8 (interquartile range: 7.9-20.1) months with appropriate therapy, PPG healed in 8 patients (53.3%) and improved in 7 (46.7%) patients, after treatment. Female gender, the presence of autoimmune disorders and a high BMI appeared to be associated with an increased risk for the development of PPG in IBD patients.

It is estimated that 23 million Germans suffer from chronic pain. A recent survey has revealed that 30 % of chronic pain patients are dissatisfied with their pain management. Furthermore, five million Germans suffer from neuropathic pain, 20 % of whom are inadequately treated. Pain is also a symptom of many dermatologic diseases, which is mostly somatic and may be classified as mild in the majority of cases. Nevertheless, research on the quality of life (QoL) has increasingly shown a marked impairment of QoL by moderate pain such as in psoriatic arthritis. -Severe pain is associated with herpes zoster (shingles), leg ulcers, and pyoderma gangrenosum. This article addresses the basics of pain classification and, in a short excerpt, pain transduction/transmission and modulation. The use of standardized diagnostic -scales is recommended for the purpose of recording and monitoring pain intensity, which allows for the optimization of therapy and consistent interdisciplinary -communication. Any dermatology residency program includes the acquisition of knowledge and skills in pain management. This review therefore aims to present fundamental therapeutic concepts based on the expanded WHO analgesic ladder, and describes a step-wise therapeutic approach and combination therapies. The article focuses on the pain management of the above-mentioned severely painful, conservatively treated dermatoses. Besides well-established therapeutic agents and current -therapeutic standards, it discusses specific options based on guidelines (where available). Current knowledge on peri- and postoperative pain management is briefly outlined. This article addresses: ▸ The fundamentals of the classification and neurophysiology of pain; ▸ Standards for pain documentation in children and adults; ▸ General standards for pharmaceutical pain management; ▸ Current specific treatment options for postherpetic neuralgia, leg ulcers, and -pyoderma gangrenosum in conjunction with the expanded WHO analgesic -ladder. © 2015 Deutsche Dermatologische Gesellschaft (DDG).

Rheumatoid arthritis (RA) is a systemic inflammatory disease which may present with extra-articular symptoms, including cutaneous manifestations. Ulcerated rheumatoid nodules, necrotic vasculitic lesions and pyoderma gangrenosum are fairly characteristic and well-recognized causes of skin ulcers in RA. However, most RA patients develop leg ulcers due to other pathophysiological factors posing a diagnostic and therapeutic challenge and leading to considerable morbidity. A retrospective chart analysis of all patients with RA and leg ulcers hospitalized at our Dermatology Department between January 1998 and March 2008 was performed to evaluate risk factors and identify underlying conditions that predispose RA patients to the development of leg ulcers. A total of 36 patients with RA and leg ulcers were identified. Three patients presented with necrotizing vasculitis and 2 with pyoderma gangrenosum. Chronic venous insufficiency was diagnosed as the underlying cause of leg ulcers in 8 patients, peripheral arterial disease in 4 patients, and combined arterial and venous malfunction in 3 patients. Five patients suffered from pressure ulcers. Interestingly, in 11 patients (31%) other underlying causes besides constricted mobility followed by secondary lymphedema could not be identified, and these ulcers were classified as 'inactivity leg ulcers'. The majority of leg ulcers in patients with RA are due to underlying venous/arterial malfunction while vasculitic or traumatic ulcers are less common. Additionally, we identified a relevant subgroup of patients with 'inactivity ulcers' due to impaired mobility and consecutive lymphedema. Morphology and localization of ulcerations as well as duplex sonography provide the most important clues for accurate diagnosis, ensuring adequate treatment. 2010 S. Karger AG, Basel.

The elimination of scabies: a task for our generation.

McLean, Florence E

2013-10-01

Scabies prevalence remains unacceptably high in many regions throughout the world. Infestation with scabies significantly impacts quality of life and is linked to pyoderma and consequently to severe long-term sequelae such as post-streptococcal glomerulonephritis. In the past, control programs using topical treatments have met with poor compliance; however, the highly effective oral agent ivermectin may offer a new paradigm in scabies management. Problems still exist with insensitive diagnostic tests, questions concerning mite reservoirs, and restrictions on who can receive ivermectin. Despite these difficulties, the elimination of scabies in communities worst affected may soon be possible. © 2013 The International Society of Dermatology.

Pyoderma gangrenosum (PG) is a painful, ulcerating skin disease with poor evidence for management. Prednisolone and ciclosporin are the most commonly used treatments, although not previously compared within a randomized controlled trial (RCT). To compare the cost-effectiveness of ciclosporin and prednisolone-initiated treatment for patients with PG. Quality of life (QoL, EuroQoL five dimensions three level questionnaire, EQ-5D-3L) and resource data were collected as part of the STOP GAP trial: a multicentre, parallel-group, observer-blind RCT. Within-trial analysis used bivariate regression of costs and quality-adjusted life years (QALYs), with multiple imputation of missing data, informing a probabilistic assessment of incremental treatment cost-effectiveness from a health service perspective. In the base case analysis, when compared with prednisolone, ciclosporin was cost-effective due to a reduction in costs [net cost: -£1160; 95% confidence interval (CI) -2991 to 672] and improvement in QoL (net QALYs: 0·055; 95% CI 0·018-0·093). However, this finding appears driven by a minority of patients with large lesions (≥ 20 cm 2 ) (net cost: -£5310; 95% CI -9729 to -891; net QALYs: 0·077; 95% CI 0·004-0·151). The incremental cost-effectiveness of ciclosporin for the majority of patients with smaller lesions was £23 374/QALY, although the estimate is imprecise: the probability of being cost-effective at a willingness-to-pay of £20 000/QALY was 43%. Consistent with the clinical findings of the STOP GAP trial, patients with small lesions should receive treatment guided by the side-effect profiles of the drugs and patient preference - neither strategy is clearly a preferred use of National Health Service resources. However, ciclosporin-initiated treatment may be more cost-effective for patients with large lesions. © 2017 The Authors.

Pyoderma gangrenosum (PG) is a rare type of autoimmune disease that results in progressive ulcers with or without previous trauma. However, PG is not well understood to date, and its treatment therefore remains a challenge. Because of the disease's systemic characteristic and the unpredictability of the clinical course, no gold standard treatment is available, especially concerning the surgical procedures to treat pyodermic lesions. Often, PG is not recognized during routine clinical practice, and standard ulcer treatment (conservative wound care, debridement, skin grafting, and local flap coverage) is initiated; this induces an autoinflammatory response, resulting in disastrous ulcers, thereby making free flap coverage necessary. The purpose of this study was to assess the outcome of microvascular free-tissue transfer as a treatment option for extended soft-tissue defects resulting from PG. We retrospectively evaluated 8 cases in 5 patients suffering from PG of the lower extremity who received defect closure with a microvascular free-tissue transfer under immunosuppressive and corticosteroid therapy. The average patient age was 60 years; three were male, and two were female. Seven defects were covered with free gracilis muscle flap. One patient received an anterolateral thigh flap. The average defect size was 93 cm 2 . No flap loss was observed during follow-up. All patients received broad-spectrum antibiotic treatment and corticosteroids. Two patients also received infliximab. PG once diagnosed is not a contraindication for microvascular free-tissue transfer. Multidisciplinary evaluation of each case is fundamental. All surgical treatments should be performed only with sufficient protective immunosuppression therapy. If the defect requires free flap coverage, it should be considered as a surgical option despite the potential risk of a pathergic response in PG and was a safe treatment option in all our cases. In conclusion, we share our experience regarding preoperative, intraoperative, and postoperative care of patients with PG receiving free flap surgery.

Complement Inhibitors from Scabies Mites Promote Streptococcal Growth – A Novel Mechanism in Infected Epidermis?

Background Scabies is highly prevalent in socially disadvantaged communities such as indigenous populations and in developing countries. Generalized itching causes discomfort to the patient; however, serious complications can occur as a result of secondary bacterial pyoderma, commonly caused by Streptococcus pyogenes (GAS) or Staphylococcus aureus. In the tropics, skin damage due to scabies mite infestations has been postulated to be an important link in the pathogenesis of disease associated with acute rheumatic fever and heart disease, poststreptococcal glomerulonephritis and systemic sepsis. Treatment of scabies decreases the prevalence of infections by bacteria. This study aims to identify the molecular mechanisms underlying the link between scabies and GAS infections. Methodology/Principal Findings GAS bacteria were pre-incubated with blood containing active complement, phagocytes and antibodies against the bacteria, and subsequently tested for viability by plate counts. Initial experiments were done with serum from an individual previously exposed to GAS with naturally acquired anti-GAS antibodies. The protocol was optimized for large-scale testing of low-opsonic whole blood from non-exposed human donors by supplementing with a standard dose of heat inactivated human sera previously exposed to GAS. This allowed an extension of the dataset to two additional donors and four proteins tested at a range of concentrations. Shown first is the effect of scabies mite complement inhibitors on human complement using ELISA-based complement activation assays. Six purified recombinant mite proteins tested at a concentration of 50 µg/ml blocked all three complement activation pathways. Further we demonstrate in human whole blood assays that each of four scabies mite complement inhibitors tested increased GAS survival rates by 2–15 fold. Conclusions/Significance We propose that local complement inhibition plays an important role in the development of pyoderma in scabies infested skin. This molecular link between scabies and bacterial infections may provide new avenues to develop alternative treatment options against this neglected disease. PMID:22815998

PAPA syndrome (Pyogenic Arthritis, Pyoderma gangrenosum, and Acne) is an autosomal dominant, hereditary auto-inflammatory disease arising from mutations in the PSTPIP1/CD2BP1 gene on chromosome 15q. These mutations produce a hyper-phosphorylated PSTPIP1 protein and alter its participation in activation of the “inflammasome” involved in interleukin-1 (IL-1β) production. Overproduction of IL-1β is a clear molecular feature of PAPA syndrome. Ongoing research is implicating other biochemical pathways that may be relevant to the distinct pyogenic inflammation of the skin and joints characteristic of this disease. This review summarizes the recent and rapidly accumulating knowledge on these molecular aspects of PAPA syndrome and related disorders. PMID:21532836

A 66-year-old man presented with a chief complaint of glans penis pain, induration, and discharge of pus. He was prescribed a course of antibiotics, but the condition persisted despite treatment. Thus, we differrentially diagnosed the patient with penile tuberculosis and pyoderma gangrenosum, and performed a biopsy of the penis. The biopsy result was thickening of the horny layer epidermis with only a foreign body granuloma composed of inflammatory cells, and did not lead to a definitive diagnosis. Thoraca-abdominal computed tomography revealed axillary lymphadenopathy with necrosis. Suspecting tuberculosis lymphadenitis, we performed T-spot and QuantiFERONtests. The result was T-spot negative and QuantiFERONpositive, so we diagnosed the patient with penile tuberculosis, and started antituberculosis medication. In about half a year after the start of treatment the symptoms subsided, and lymphadenopathy showed reduction.

2011-01-01

The differential of scalp ulceration in older patients should include several causes, such as herpes zoster, irritant contact dermatitis, ulcerated skin tumors, postirradiation ulcers, microbial infections, pyoderma gangrenosum, and giant cell arteritis. Scalp necrosis associated with giant cell arteritis was first described in the 1940s. The presence of this dermatological sign within giant cell arteritis represents a severity marker of this disease, with a higher mean age at diagnosis, an elevated risk of vision loss and tongue gangrene, as well as overall higher mortality rates, in comparison to patients not presenting this manifestation. Even though scalp necrosis due to giant cell arteritis is exceptional, a high level of suspicion must be held for this clinical finding, in order to initiate prompt and proper treatment and avoid blindness.

Increasing multidrug resistance amongst canine pathogenic staphylococci has renewed interest in topical antibacterial therapy for skin infections in the context of responsible veterinary prescribing. We therefore determined the activity in vitro of three clinically relevant topical agents and synergism between two of them against Staphylococcus pseudintermedius and Staphylococcus aureus. The MICs of fusidic acid (n = 199), chlorhexidine (n = 198), miconazole (n = 198) and a 1:1 combination of miconazole/chlorhexidine (n = 198) were determined for canine isolates [50 MRSA and 49 methicillin-resistant S. pseudintermedius (MRSP), 50 MSSA and 50 methicillin-susceptible S. pseudintermedius (MSSP)] collected from the UK and Germany using an agar dilution method (CLSI VET01-A4). Fractional inhibitory concentration (FIC) indices were calculated to assess the interaction of miconazole with chlorhexidine. MICs of each drug/combination were significantly (P < 0.0005) higher for S. aureus when compared with S. pseudintermedius. Most strains (n = 172) had an MIC of fusidic acid of ≤0.03 mg/L (MIC ≥64 mg/L, n = 5 MRSA). All strains had MICs of chlorhexidine of 0.5-4 mg/L, except for one MRSA (MIC = 8 mg/L). All but four strains had MICs of miconazole of 1-4 mg/L (MIC = 16 mg/L, n = 3; MIC = 256 mg/L, n = 1). Miconazole/chlorhexidine (1:1 ratio) had a synergistic effect against 49/50 MRSA, 31/50 MSSA, 12/49 MRSP and 23/49 MSSP. Since the majority of these staphylococci, including methicillin-resistant isolates, had MICs that should be readily exceeded by topical skin application of these agents, their therapeutic efficacy for canine superficial pyoderma should be assessed. The synergistic interaction shown in vitro supports further clinical evaluation of miconazole/chlorhexidine combination therapy for staphylococcal infection. © The Author 2015.

Adalimumab in dermatology

Traczewski, Pawel; Rudnicka, Lidia

2008-01-01

Adalimumab is a biological agent, one of the tumour necrosis factor-alpha inhibitors. Pivotal studies evaluating its efficacy in plaque psoriasis (CHAMPION, REVEAL) and psoriatic arthritis (PsA) (ADEPT) were carried out in recent years. Adalimumab proved highly effective in psoriasis patients and in PsA patients previously unresponsive to nonsteroidal anti-inflammatory drugs.

Adalimumab is a biological agent, one of the tumour necrosis factor-alpha inhibitors. Pivotal studies evaluating its efficacy in plaque psoriasis (CHAMPION, REVEAL) and psoriatic arthritis (PsA) (ADEPT) were carried out in recent years. Adalimumab proved highly effective in psoriasis patients and in PsA patients previously unresponsive to nonsteroidal anti-inflammatory drugs. Results of smaller studies suggest therapy with the drug may be successful in psoriasis resistant to other biologics and PsA unresponsive to disease-modifying antirheumatic drugs. Adalimumab has also been shown to improve patients' quality of life significantly. Although they should be further extended as far as dermatological conditions are concerned, available data indicate adalimumab is safe and well tolerated. Numerous case reports featuring its off-label use suggest the drug could be helpful in treating hidradenitis suppurativa, pyoderma gangrenosum, Sweet's syndrome, cutaneous sarcoidosis, pemphigus, systemic vasculitides, multicentric reticulohistiocytosis and stomatitis.

Canine eosinophilic folliculitis and furunculosis in three cases.

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.

Bacterial skin infections: management of common streptococcal and stapylococcal lesions.

PubMed

Witkowski, J A; Parish, L C

Skin infection occurs in any age-group, sex, and race but is particularly common in children. It is usually minor, but may indicate underlying systemic disease or may lead to systemic infection. Streptococci and staphylococci are common causes. Group A beta-hemolytic streptococci account for the majority of streptococcal infections in man. Infection most often involves the lower extremities and produces spreading erythema and necrosis but little purulence. Staphylococcal infections most commonly involve the face, the hair follicles and eccrine sweat ducts being the initial sites. Lesions appear as bullae and pustules with a narrow rim of erythema. Intense cellulitis surrounding the lesions usually points to a virulent, penicillin-resistant strain of Staphylococcus. Treatment of both types of infection consists of cleansing with antibacterial agents, removal of crusts, application of warm compresses, and use of topical or systemic antibiotics, depending on the severity of the infection and the type of pyoderma involved.

Report of the regional vascular service center of Smolensk work and work of vascular service of Smolensk region were analyzed. The aim of the study is to analyze work of the vascular service in Smolensk and Smolensk region in 2009-2014. Mortality and morbidity in patients with cardio-vascular diseases in Smolensk Region are higher than in other regions of Russia. Recently a number of patients hospitalized to vascular service centers are increased. Infectious complications (pneumonia, bedsores, pyoderma) take lead place in mortality. Nowadays it's very important to solve the problem with prophylaxis of infectious complications in patients with acute ischemic stroke, also to solve problem with rehabilitation in patients with mild and severe motor disorders and disorders of praxis, gnosis. Continuous training of doctors and nurses in regional vascular service centers is needed. It will increase quality of medical service and improve rehabilitation prognosis in patients with ischemic stroke.

Almost one-third of patients with inflammatory bowel disease (IBD) develop skin lesions. Cutaneous disorders associated with IBD may be divided into 5 groups based on the nature of the association: specific manifestations (orofacial and metastatic IBD), reactive disorders (erythema nodosum, pyoderma gangrenosum, pyodermatitis-pyostomatitis vegetans, Sweet’s syndrome and cutaneous polyarteritis nodosa), miscellaneous (epidermolysis bullosa acquisita, bullous pemphigoid, linear IgA bullous disease, squamous cell carcinoma-Bowen’s disease, hidradenitis suppurativa, secondary amyloidosis and psoriasis), manifestations secondary to malnutrition and malabsorption (zinc, vitamins and iron deficiency), and manifestations secondary to drug therapy (salicylates, immunosupressors, biological agents, antibiotics and steroids). Treatment should be individualized and directed to treating the underlying IBD as well as the specific dermatologic condition. The aim of this review includes the description of clinical manifestations, course, work-up and, most importantly, management of these disorders, providing an assessment of the literature on the topic.

Autoimmune paraneoplastic syndromes are commonly encountered in patients with myelodysplastic syndromes (MDS). A review of case reports and small series suggest as many as 10% of MDS patients may experience various autoimmune syndromes. Clinical manifestations of such phenomena may include an acute systemic vasculitic syndrome, skin vasculitis, fever, arthritis, pulmonary infiltrates, peripheral polyneuropathy, inflammatory bowel disease, glomerulonephritis, and even classical connective tissue disorders, such as relapsing polychondritis. On the other hand, asymptomatic immunologic abnormalities have also been reported in these patients. These autoimmune manifestations frequently respond to immunosuppressive agents including steroids and occasional hematologic responses to steroid therapy have also been reported. We report five patients with history of MDS who manifested different spectrums of autoimmune phenomena including: pyoderma gangrenosum (PG), vasculitis, Coombs negative hemolytic anemia, idiopathic thrombocytopenia, and chronic inflammatory demyelinating polyneuropathy (CIDP). We also review the incidence, nature, course and response to therapy of these manifestations and discuss potential pathogenic mechanisms.

X-linked agammaglobulinemia (XLA) is a primary immunodeficiency characterized by a failure to generate immunoglobulins of all isotypes due to the absence of mature B cells and plasma cells, secondary to mutations in the Bruton's tyrosine kinase (Btk) gene. We report six patients with XLA, confirmed by mutation analysis, from northern Thailand. The mean age of onset was 2.5 years and the mean age at diagnosis was 7.3 years. All patients had a history of otitis media, pneumonia and arthritis at the time of diagnosis, five patients had developed bronchiectasis and 3 patients septicemia. Other infections reported included sinusitis (5/6), pericarditis (1/6), meningitis (1/6) and pyoderma (1/6). Haemophilus influenzae, Streptococcus pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus were isolated on multiple occasions. One patient died of sepsis at the age of 16 years. These observations demonstrate that early diagnosis and treatment can improve prognosis and quality of life.

Pyoderma gangrenosum (PG) is a rare inflammatory skin disorder characterised by painful and rapidly progressing skin ulceration. PG can be extremely difficult to treat and patients often require systemic immunosuppression. Recurrent lesions of PG are common, but the relative rarity of this condition means that there is a lack of published evidence regarding its treatment. A systematic review published in 2005 found no randomised controlled trials (RCTs) relating to the treatment of PG. Since this time, one small RCT has been published comparing infliximab to placebo, but none of the commonly used systemic treatments for PG have been formally assessed. The UK Dermatology Clinical Trials Network's STOP GAP Trial has been designed to address this lack of trial evidence. The objective is to assess whether oral ciclosporin is more effective than oral prednisolone for the treatment of PG. The trial design is a two-arm, observer-blind, parallel-group, randomised controlled trial comparing ciclosporin (4 mg/kg/day) to prednisolone (0.75 mg/kg/day). A total of 140 participants are to be recruited over a period of 4 years, from up to 50 hospitals in the UK and Eire. Primary outcome of velocity of healing at 6 weeks is assessed blinded to treatment allocation (using digital images of the ulcers). Secondary outcomes include: (i) time to healing; (ii) global assessment of improvement; (iii) PG inflammation assessment scale score; (iv) self-reported pain; (v) health-related quality of life; (vi) time to recurrence; (vii) treatment failures; (viii) adverse reactions to study medications; and (ix) cost effectiveness/utility. Patients with a clinical diagnosis of PG (excluding granulomatous PG); measurable ulceration (that is, not pustular PG); and patients aged over 18 years old who are able to give informed consent are included in the trial. Randomisation is by computer generated code using permuted blocks of randomly varying size, stratified by lesion size, and presence or absence of underlying systemic disease (for example, rheumatoid arthritis).Patients who require topical therapy are asked to enter a parallel observational study (case series). If topical therapy fails and systemic therapy is required, participants are then considered for inclusion in the randomised trial. Current controlled trials: ISRCTN35898459.

The classic pathology of skin disease discontinuous from the inflamed gastrointestinal (GI) tract in patients with Crohn's disease (CD) includes pyoderma gangrenosum (PG), erythema nodosum (EN), and so-called metastatic Crohn's disease. The purpose of this study was two-fold: First, we explored the full spectrum of cutaneous lesions associated with Crohn's disease, and second, we sought to explore a potential molecular basis of the skin lesions in patients with CD. In this regard, we analyzed skin and GI tract biopsies from affected patients for the consensus bacterial SrRNA to determine whether direct bacterial infection was associated with either condition. Formalin-fixed, paraffin-embedded sections were studied and correlated to clinical presentation and histories from 33 patients with CD. Consensus bacterial RNA sequences were analyzed using an RT in situ PCR assay on both skin biopsy and GI biopsy material. The GI tract material included biopsies from 3 patients who had skin lesions and from 7 patients in whom there were no known skin manifestations. There were 8 cases of neutrophilic dominant dermal infiltrates, including pyoderma gangrenosum, 6 cases of granuloma annulare/necrobiosis lipoidica-like lesions, 5 cases of sterile neutrophilic folliculitis, 5 cases of panniculitis, 4 cases of vasculitis, 2 cases of psoriasis, 2 cases of lichenoid and granulomatous inflammation, and 1 case of classic metastatic CD. Intracellular bacterial 16S rRNA was detected in 8 of 10 tissues of active CD in the GI tract, of which 3 of the cases tested were from patients who also developed skin lesions at some point in their clinical course; in contrast, none of the skin biopsies had detectable bacterial RNA. The dermatopathological manifestations of CD discontiguous from the involved GI tract mucosa have in common a vascular injury syndrome, typically with a prominent extravascular neutrophilic and/or histiocytic dermal infiltrate. In addition, this study, the first to document in situ intracellular consensus bacterial SrRNA in the GI tract in CD, suggests that hematogenous dissemination of viable microbes is not associated with the cutaneous manifestations of this disease. Bacteria do, however, appear to play a role in bowel lesions of patients with CD.

Pyoderma gangrenosum (PG) is a rare ulcerative skin disease, part of the spectrum of neutrophilic and auto-inflammatory dermatoses. Its pathogenesis is unknown, although immune pathways have been implicated. Lesion biopsies show a predominantly neutrophilic infiltrate. The incidence of PG is uncertain, but it is estimated to be 3-10 per million per year, occurring at any age but most commonly between 20 and 50 years with a possible slightly higher incidence in women. Approximately 50% of patients with PG also have another disease associated with PG. The most common is inflammatory bowel disease (IBD), particularly Crohn's and ulcerative colitis (UC). Local treatment may be sufficient for mild cases, while for severe cases systemic immunosuppressants are the mainstay (1,2). We report the case of a patient with bullous PG and UC successfully treated with infliximab and azathioprine. A 32-year-old male Caucasian patient presented with painful violaceous vesicles and enlarging bullae of various sizes and with acute onset, located on the trunk and bilaterally on both the lower and the upper extremities. Lesions on the trunk were composed of hemorrhagic pustules with a surrounding erythematous overhanging border. Some of the lesions had undergone central necrosis and ulceration (Figure 1, a-d). The patient reported of the lesions had appeared one week ago, simultaneously with the exacerbation of a known inflammatory bowel disease with hemorrhagic mucoid diarrhea and fever of up to 38.5°C. The patient's medical history included UC affecting the whole colon (pancolitis), diagnosed 5 months prior to the onset of the epidermal lesions, for which the patient was receiving treatment with oral prednisolone 10 mg/day and mesalazine granules. Blood tests showed severe anemia, leukocytosis, and increased inflammatory markers (C-reactive protein, erythrocyte sedimentation rate). Antinuclear antibodies (ANA), anti-double stranded DNA (anti-dsDNA) andtibodies, antineutrophil cytoplasmic antibodies (cANCA), perinuclear neutrophil antibodies (p-ANCA), antiphospholipid antibodies, and tumor markers were within normal limits. The patient was negative for cryoglobulins, viral hepatitis (B, C) and human immunodeficiency virus (HIV). Blood cultures were negative. Microscopy and cultures for mycobacteria and fungi gave negative results. Stool samples tested negative for infections agents. The Mantoux skin test was negative. Colonoscopy showed severe pancolitis, and biopsies from the rectum and sigmoid colon were consistent with chronic ulcerative colitis. Abdominal ultrasound and chest and abdominal X-rays did not result in significant findings. Because of severe anemia, the patient received 2 blood transfusions. The histopathologic examination carried out on the erythematous border of a lesion on the lower leg showed a neutrophilic infiltrate, confined to the dermis. On the basis of clinical findings, the diagnosis of PG was established. Topical wound care consisted of local wound care and a topical corticosteroid. Systemic therapy was initiated with 40 mg/day methylprednisolone for 7 days, 30 mg/day for 7 days, then 25 mg/day, and then tapered down further. The patient received an infusion of infliximab 7.5 mg/kg at weeks 0, 2, and 6 and every 8 weeks thereafter. After week 2, oral azathioprine 2.5 mg/kg daily was added to the treatment. The patient also received mesalazine tablets (2 g ×2/day) and mesalazine enema (1-2/day). The patient showed good response to treatment, with clinical remission of skin lesions. Lesions healed with characteristic thin, atrophic scars (Figure 2, a-d). At 7-month follow-up the patient was continuing with infusions of infliximab 7.5 mg/kg and azathioprine 2.5 mg/kg and was still in remission. We reported our experience with a case of generalized bullous pyoderma gangrenosum associated with ulcerative colitis. Generalized pyoderma gangrenosum is very rare. Bullous or atypical PG was first described by Perry and Winklemann in 1972 (1). Brunsting et al. coined the term pyoderma gangrenosum (PG) to describe a series of patients with recurrent ulcerations (3). The incidence of this disease is uncertain. Its pathogenesis is unknown, but an immunological background has been suggested. In approximately 50% of patients, an underlying immunological disease is present, commonly inflammatory bowel disease (IBD) (4-6). In larger series of patients with PG, approximately 50% present with a primary disorder. Ulcerative colitis is found in 10-15% of cases. Crohn's disease is associated with PG closed than UC. Less than 3% of patients with Crohn's disease or UC develop PG (6). PG is characterized by cutaneous ulcerations with mucopurulent or hemorrhagic exudate. It begins as an inflammatory pustule with a surrounding halo that enlarges and begins to ulcerate. These very painful ulcers present with undermined bluish borders with surrounding erythema. The lesions of PG most commonly occur on the legs, but they may occur anywhere on the body. The clinical picture of PG is very characteristic. Therefore the diagnosis of PG is based firstly on clinical signs and on the patient's history of underlying diseases and then supported by biopsy. PG has four distinctive clinical and histological variants. Some have morphological and histological features that overlap with other reactive neutrophilic skin conditions. There are no diagnostic serologic features (6,7). There is no evidence that the efficacy of treatment strategies for PG differs between IBD and non-IBD patients. For patients with a diffuse disease or rapidly progressive process, systemic treatment is essential. Immunosuppression is the mainstay of treatment. Traditionally, the most commonly used drugs with the best clinical experience are systemic corticosteroids. Corticosteroids have been considered as first line treatment (6,8). As reported by the European Crohn's and Colitis Organisation (ECCO) in 2008, an evidence-based consensus on the management of special situations in patients with ulcerative colitis, systemic corticosteroids are recommended (9). Treatment with corticosteroids (e.g. prednisolone 1-2 mg per kg/day or pulse therapy with 1 g of methylprednisolone) aims to prevent progression and rapidly stop inflammation (6). Additional mesalamine and corticosteroids may be effective in patients with bowel disease (10). In recent years, tumor necrosis alpha (TNF-α) inhibitors, such as infliximab and adalimumab, were reported to be effective for PG associated with IBD. These drugs block the biological activity of TNF-α, which effects regulatory T cells, restoring their capacity to inhibit cytokine production. The TNF-α inhibitors thus suppress the inflammatory processes that is involved in the pathogenesis of PG (11). Infliximab, a chimeric monoclonal antibody, is given by infusion at weeks 0, 2, and 6 and then every 8 weeks, usually at a dosage of 5 mg/kg. UC of patients with frequent disease relapse or those that are resistant or dependent on corticosteroids is often treated with purine antimetabolites, such as azathioprine (AZA) (10). AZA, a purine antimetabolite (2.5 mg per kg/day) is administered for its steroid-sparing effects. The response occurs after 2 to 4 weeks (6, 10). Infliximab can be combined with AZA. Patients with UC treated with infliximab plus AZA were more likely to achieve corticosteroid-free remission at 16 weeks than those receiving either monotherapy (10,12).

Karimi, Karen; Odhav, Ashika; Kollipara, Ramya; Fike, Jesse; Stanford, Carol; Hall, John C

Acute cutaneous necrosis is characterised by a wide range of aetiologies and is associated with significant morbidity and mortality, warranting complex considerations in management. Early recognition is imperative in diagnosis and management of sudden gangrenous changes in the skin. This review discusses major causes of cutaneous necrosis, examines the need for early assessment, and integrates techniques related to diagnosis and management. The literature, available via PubMed, on acute cutaneous necrotic syndromes was reviewed to summarise causes and synthesise appropriate treatment strategies to create a clinician's guide in the early diagnosis and management of acute cutaneous necrosis. Highlighted in this article are key features associated with common causes of acute cutaneous necrosis: warfarin-induced skin necrosis, heparin-induced skin necrosis, calciphylaxis, pyoderma gangrenosum, embolic phenomena, purpura fulminans, brown recluse spider bite, necrotising fasciitis, ecthyma gangrenosum, antiphospholipid syndrome, hypergammaglobulinemia, and cryoglobulinemia. This review serves to increase recognition of these serious pathologies and complications, allowing for prompt diagnosis and swift limb- or life-saving management.

Auto-inflammatory syndromes are a new group of distinct hereditable disorders characterized by episodes of seemingly unprovoked inflammation (most commonly in skin, joints, gut, and eye), the absence of a high titer of auto-antibodies or auto-reactive T cells, and an inborn error of innate immunity. A narrative literature review was carried out of studies related to auto-inflammatory syndromes to discuss the pathogenesis and clinical manifestation of these syndromes. This review showed that the main monogenic auto-inflammatory syndromes are familial Mediterranean fever (FMF), mevalonate kinase deficiency (MKD), Blau syndrome, TNF receptor-associated periodic syndrome (TRAPS), cryopyrin-associated periodic syndrome (CAPS), and pyogenic arthritis with pyoderma gangrenosum and acne (PAPA). The data suggest that correct diagnosis and treatment of monogenic auto-inflammatory diseases relies on the physicians' awareness. Therefore, understanding of the underlying pathogenic mechanisms of auto-inflammatory syndromes, and especially the fact that these disorders are mediated by IL-1 secretion stimulated by monocytes and macrophages, facilitated significant progress in patient management.

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

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.

Ulcerative colitis is occasionally complicated by dermatological disorders presenting as extra-intestinal manifestations, including erythema nodosum and pyoderma gangrenosum. Sweet's syndrome is considered to be a rare cutaneous disease in patients with ulcerative colitis. To date, only 17 cases of Sweet's syndrome complicating ulcerative colitis have been reported in the English literature. Here, we report a case of a 41-year-old male who had been suffering from ulcerative colitis for 20 years. He was admitted to hospital with hematochezia, diarrhea and fever, and painful erythematous nodules on the face and arms. Histological examination of skin biopsies showed inflammatory cell infiltration composed mainly of neutrophils without evidence of necrotizing vasculitis, and the condition was diagnosed as Sweet's syndrome. The patient was treated with prednisolone and leukocytapheresis and the erythematous nodules on the skin, as well as the abdominal symptoms and endoscopic findings of ulcerative colitis, immediately improved. In this paper we report on this case and review the literature concerning ulcerative colitis and Sweet's syndrome.

Immunosuppressive drugs are commonly used for the treatment of inflammatory bowel disease. Patients receiving immunosuppressants are susceptible to a variety of infections with opportunistic pathogens. We present a case of skin infection with Mycobacterium chelonae in a 60-year-old Caucasian woman with ulcerative colitis who had been treated with corticosteroids and azathioprine. The disease manifested with fever and rash involving the right leg. Infliximab was administered due to a presumptive diagnosis of pyoderma gangrenosum, leading to worsening of the clinical syndrome and admission to our hospital. Routine cultures from various sites were all negative. However, Ziehl-Neelsen staining of pus from the lesions revealed acid-fast bacilli, and culture yielded a rapidly growing mycobacterium further identified as M. chelonae. The patient responded to a clarithromycin-based regimen. Clinicians should be aware of skin lesions caused by atypical mycobacteria in immunocompromised patients with inflammatory bowel disease. Furthermore, they should be able to thoroughly investigate and promptly treat these conditions.

Churg-Strauss syndrome (CSS) is a rare systemic vasculitis that affect small and medium-sized blood vessels and is accompanied by asthma, eosinophilia, and peripheral neuropathy. This report describes a case of a 52-year-old man who had a history of sinusitis, asthma, and thymus cancer and who had complained of bilateral lower extremity paresthesia and weakness for a month. Peripheral neuropathy was detected by electrodiagnostic studies. Resection of a mediastinal mass, which was diagnosed as thymic neuroendocrine carcinoma, was performed five months before his visit. After thymectomy, peripheral blood tests revealed a gradual increase in eosinophils. Two months after surgery, he was admitted to the hospital for dyspnea, and nodules of focal consolidation were found in his chest X-ray. One month later, pyoderma occurred in the right shin, and the skin biopsy showed extravascular eosinophilic infiltration. He was diagnosed with CSS after thymectomy, and we report a very rare case of CSS presented with thymic neuroendocrine carcinoma.

Streptococcus pyogenes (group A streptococcus, GAS) causes a wide range of clinical manifestations ranging from mild self-limiting pyoderma to invasive diseases such as sepsis. Also of concern are the post-infectious immune-mediated diseases including rheumatic heart disease. The development of a vaccine against GAS would have a large health impact on populations at risk of these diseases. However, there is a lack of suitable models for the safety evaluation of vaccines with respect to post-infectious complications. We have utilized the Lewis Rat model for cardiac valvulitis to evaluate the safety of the J8-DT vaccine formulation in parallel with a rabbit toxicology study. These studies demonstrated that the vaccine did not induce abnormal pathology. We also show that in mice the vaccine is highly immunogenic but that 3 doses are required to induce protection from a GAS skin challenge even though 2 doses are sufficient to induce a high antibody titer.

ABSTRACT Streptococcus pyogenes (group A streptococcus, GAS) causes a wide range of clinical manifestations ranging from mild self-limiting pyoderma to invasive diseases such as sepsis. Also of concern are the post-infectious immune-mediated diseases including rheumatic heart disease. The development of a vaccine against GAS would have a large health impact on populations at risk of these diseases. However, there is a lack of suitable models for the safety evaluation of vaccines with respect to post-infectious complications. We have utilized the Lewis Rat model for cardiac valvulitis to evaluate the safety of the J8-DT vaccine formulation in parallel with a rabbit toxicology study. These studies demonstrated that the vaccine did not induce abnormal pathology. We also show that in mice the vaccine is highly immunogenic but that 3 doses are required to induce protection from a GAS skin challenge even though 2 doses are sufficient to induce a high antibody titer.

Skin manifestations are common in patients with inflammatory bowel diseases (IBD) and can be part of a concomitant illness with a shared genetic background, an extra-intestinal manifestation of the disease, or a drug side-effect. Areas covered: We provide a practical overview of the epidemiology, pathogenesis, diagnosis, therapeutic approach and prognosis of the most frequent disease-related and drug-induced cutaneous manifestations in IBD, illustrated by cases encountered in our clinical practice. Among the most frequently encountered IBD-related lesions are erythema nodosum, pyoderma gangrenosum and Sweet's syndrome. Common skin manifestations with a strong association to TNF antagonists are local injection site reactions, psoriasiform lesions, cutaneous infections, vasculitides and lupus-like syndromes. In addition, we discuss the relation of thiopurines and TNF antagonists with the risk of skin cancer. Expert commentary: We hope this review will help caretakers involved in the management of IBD patients to recognize the lesions and to manage them in close collaboration with a dedicated dermatologist.

Infliximab is an accepted induction and maintenance treatment for patients with Crohn's disease. The effectiveness of infliximab has been demonstrated for both active luminal disease and for enterocutaneous fistulisation. In addition, infliximab can be administered for extraintestinal symptoms of Crohn's disease, such as pyoderma gangrenosum, uveitis and arthropathy. Maintenance treatment with infliximab is effective and is regarded as safe as long as the necessary safety measures are heeded. Infusion reactions occur in 3 to 17% of the patients and are associated with the formation of antibodies to infliximab. A reduction in infusion reactions is possible by the concurrent administration of steroids and the use of immunosuppressants (azathioprine, 6-mercaptopurine, methotrexate). Furthermore, immunosuppressants increase the duration of the response to infliximab. For these reasons, the concomitant use of immunosuppressants with infliximab is recommended. Infections and most specifically tuberculosis need to be ruled out before infliximab is administered. Up to now, there are no indications for a connection between an increased risk for malignancies and treatment with infliximab.

Postvaccination wounds associated predominantly with Arcanobacterium phocae in mink (Neovison vison) at three mink farms.

The emerging skin disease fur animal epidemic necrotic pyoderma (FENP) has been attributed to infection with Arcanobacterium phocae (ABP). The exact pathogenesis and risk factors of FENP have yet to be elucidated. Three mink from each of three different mink farms (A-C) with postvaccination skin wounds at the vaccination site and six mink from an unaffected mink farm (D) that had used the same vaccine batch and vaccination site (hind leg). All mink from farms A-C had severe necrotizing to necropurulent dermatitis where they were vaccinated intramuscularly in the hind leg. ABP was the sole bacterium cultured from six of nine wounds. Using 16S-23S rDNA intergenic spacer region and BOX-PCR, the ABP isolates from these wounds were indistinguishable from isolates originating from several cases of FENP. This is the first report of FENP-like lesions at the site of vaccination, in the days following the procedure, associated with ABP. At farms with FENP vaccination, procedures should be considered carefully. © 2016 ESVD and ACVD.

Adult-onset demodicosis in two dogs due to Demodex canis and a short-tailed demodectic mite.

1999-11-01

Infestation with a short-tailed demodectic mite and Demodex canis was diagnosed in both a six-and-a-half-year-old and a four-year-old dog. The clinical picture was compatible with generalised demodicosis complicated by staphylococcal pyoderma (case 1), or localised demodicosis (case 2). In both cases, the short-tailed demodectic mite outnumbered D canis in superficial skin scrapings. The laboratory findings (lymphopenia, eosinopenia, increased serum alkaline phosphatase and alanine aminotransferase activities, diluted urine and proteinuria) and the results of a low dose dexamethasone suppression test were suggestive of underlying hyperadrenocorticism in the first case. Hypothyroidism was considered a possibility in the second case, owing to the sustained bradycardia and the extremely low basal total thyroxine value. Systemic treatment with ivermectin and cephalexin (case 1), or topical application of an amitraz solution in mineral oil, along with sodium levothyroxine replacement therapy (case 2), resulted in a complete resolution of the skin lesions and the disappearance of both types of demodectic mite after two and one and a half months, respectively.

[Therapeutic administration of immunoglobulins].

Intravenously administered immunoglobulins have multiple modes of action that are anti-inflammatory. They can therefore be beneficial in a number of autoimmune disorders. The aim of this article is to analyze and summarize studies on the administration of intravenous immunoglobulins in rheumatological diseases. A selective search and analysis of the literature was carried out related to the mode of action and efficacy of intravenous immunoglobulins in rheumatological diseases. Intravenous immunoglobulins have a broad mode of action and can therefore be beneficial in almost all autoimmune diseases. Conditions in which they are of special benefit include immunothrombopenia (ITP), Kawasaki disease and idiopathic inflammatory myopathies. In rare situations, they may also be indicated in systemic lupus erythematosus (SLE), Sjögren's syndrome and neuropathies, catastrophic antiphospholipid syndrome (APS), scleroderma, antineutrophil cytoplasmic antibody (ANCA) associated vasculitis, pyoderma gangrenosum and scleromyxedema. Severe adverse events are rare. In view of the high costs of the therapy, intravenous immunoglobulins are mostly applied in emergency situations, as salvage therapy when other standard therapies have failed or when severe infections are a contraindication to the administration of immunosuppressants.

Thalidomide is a synthetic glutamic acid derivative first introduced in 1956 in Germany as an over the counter medications. It was thought to be one of the safest sedatives ever produced as it was effective in small doses, was not addictive, and did not have acute side-effects such as motor impairment, but was quickly removed from market after it was linked to cases of severe birth defects. The Food and Drug Administration approved use in the treatment of erythema nodosum leprosum. Further, it was shown its effectiveness in unresponsive dermatological conditions such as actinic prurigo, adult Langerhans cell hystiocytosis, aphthous stomatitis, Behçet syndrome, graft-versus-host disease, cutaneous sarcoidosis, erythema multiforme, Jessner-Kanof lymphocytic infiltration of the skin, Kaposi sarcoma, lichen planus, lupus erythematosus, melanoma, prurigo nodularis, pyoderma gangrenosum and others. In May 2006, it was approved for the treating multiple myeloma. New thalidomide analogues have been developed but lack clinical experience. This paper is a review of the history, pharmacology, mechanism of action, clinical applications and side effects of thalidomide and its analogues. Copyright © 2013 Elsevier España, S.L.

Degos' disease: a distinctive pattern of disease, chiefly of lupus erythematosus, and not a specific disease per se.

PubMed

Ball, Elizabeth; Newburger, Amy; Ackerman, A Bernard

2003-08-01

Degos' disease, known confusingly as malignant strophic papularis, is an uncommon condition of unknown cause characterized by distinctive infarctive lesions in the skin, gastrointestinal tract, and central nervous system; the lesions at the two latter sites often result in death. We deem Degos' disease to be analogous to lupus erythematosus in the sense that each is fundamentally a systemic pathologic process involving several organs, among them the skin, but, moreover, we regard Degos' disease, in most instances, to be an actual manifestation of lupus erythematosus. Histopathologically, the findings in sections of tissue of skin lesions of Degos' disease are indistinguishable from those of one expression of cutaneous lupus erythematosus; immunopathologically, some patients with morphologic findings stereotypical of Degos' disease display signs characteristic of lupus erythematosus. For these reasons, we consider Degos' disease to be a distinctive pattern of disease, rather than a specific disease per se, just as are erythema multiforme, erythema nodosum, leukocytoclastic vasculitis, Sweet's syndrome, and pyoderma gangrenosum, to name but five of scores of them. The singular pattern that is designated Degos' disease usually is an expression of lupus erythematosus, but, episodically, of conditions like dermatomyositis and rheumatoid arthritis.

Adverse interaction between colchicine and ketoconazole in a Chinese shar pei.

A Chinese shar pei with a 2 yr history of episodic fever, lethargy, and shifting lameness was presumptively diagnosed with familial shar pei fever but had never been treated for the syndrome. After being presented for a superficial pyoderma with possible dermatophyte coinfection, treatment with a cephalosporin and ketoconazole were prescribed. One wk later, colchicine was initiated for familial shar pei fever using cautious dose escalation. Nevertheless, gastrointestinal toxicity, skeletal muscle myopathy, and hepatotoxicity developed within 2 wk. Abrupt resolution of gastrointestinal toxicity and myopathy followed drug withdrawal. However, escalating liver enzyme activity and hyperbilirubinemia led to liver biopsy to rule out an antecedent hepatopathy. Biopsy characterized canalicular cholestasis and colchicine-associated metaphase arrest and ring mitoses reflecting repression of mitotic spindle formation. Signs of illness completely resolved 3 mo after drug discontinuation. Although avoidable adverse interactions between ketoconazole and drugs reliant on cytochrome oxidase biotransformation and/or drug efflux mediated by multiple drug-resistant transporters are well documented in humans, these are rarely reported in veterinary patients. This case exemplifies an important and avoidable ketoconazole/colchicine drug interaction from which the patient completely recovered. The dog tested negative for the canine MDR1 loss of function mutation that also might potentiate colchicine toxicity.

Current use of anti-infectives in dermatology.

Dermatologic diseases encompass a broad category of pathologic situations. Infection remains a significant aspect of the pathology faced in patient encounters, and it is natural to expect that anti-infectives play a major element in the armamentarium utilized by dermatologists. Aside from the treatment of the classic bacterial and fungal infections, there are now new uses for antiviral agents to help suppress recurrent disease, such as herpes simplex. There is also the novel approach of using anti-infectives, or agents that have been thought to have antimicrobial activity, to treat inflammatory diseases. This review describes anti-infectives, beginning with common antibiotics used to treat bacterial infections. The discussion will then cover the current use of antivirals. Finally, the description of antifungals will be separated, starting with the oral agents and ending with the topical antimycotics. The use of anti-infectives in tropical dermatology has been purposefully left out, and perhaps should be the subject of a separate review. Cutaneous bacterial infections consist chiefly of those microorganisms that colonize the skin, such as species of staphylococcus and streptococcus. Propionibacterium acnes and certain other anaerobes can be involved in folliculitis, pyodermas and in chronic conditions such as hidradenitis suppurativa.

PBP-2 Negative Methicillin Resistant Staphylococcus schleiferi Bacteremia from a Prostate Abscess: An Unusual Occurrence

2016-01-01

Staphylococcus schleiferi subsp. schleiferi is a coagulase-negative Staphylococcus which has been described as a pathogen responsible for various nosocomial infections including bacteremia, brain abscess, and infection of intravenous pacemakers. Recently, such bacteria have been described to be found typically on skin and mucosal surfaces. It is also believed to be a part of the preaxillary human flora and more frequently found in men. It is very similar in its pathogenicity with Staphylococcus aureus group and expresses a fibronectin binding protein. Literature on this pathogen reveals that it commonly causes otitis among dogs because of its location in the auditory meatus of canines. Also, it has strong association with pyoderma in dogs. The prime concern with this organism is the antibiotic resistance and relapse even after appropriate treatment. Very rarely, if any, cases have been reported about prostatic abscess (PA) with this microbe. Our patient had a history of recurrent UTIs and subsequent PA resulting in S. schleiferi bacteremia in contrast to gram negative bacteremia commonly associated with UTI. This organism was found to be resistant to methicillin, in spite of being negative for PBP2, which is a rare phenomenon and needs further studies. PMID:27092283

We report the case of a female patient who developed polymorphic expressions of neutrophilic dermatosis associated with p-ANCA while receiving benzylthiouracil for hyperthyroidism. A 41-year-old-woman was treated with benzylthiouracil for Basedow's disease. After 21 months of therapy, she developed fever with different expressions of neutrophilic dermatosis: pyoderma gangrenosum of feet, Sweet's syndrome of the forearms and the face. Biopsies confirmed the diagnosis of neutrophilic dermatosis. The histological examination of a skin specimen taken from the developing border of a foot lesion showed polynuclear neutrophilic infiltration with leucocytoclastic vasculitis and the presence of anti-myeloperoxydase p-ANCA. Abdominal ultrasound showed multiple splenic microabscesses. The myelogram, gastroscopy and colonoscopy findings were normal. Benzylthiouracil was stopped and systemic corticosteroid therapy resulted in regression of the skin lesions and splenic microabscesses. Different types of neutrophilic dermatosis were described in our case, confirming the notion of neutrophilic dermatosis continuum. The occurrence of neutrophilic dermatosis and p-ANCA after benzylthiouracil therapy suggests the involvement of polynuclear neutrophils in a common pathogenic mechanism. However, to date there have been no other reports analogous to ours, and inclusion of neutrophilic dermatosis as a benzylthiouracil-induced adverse effect would require confirmation by other instances of such associations.

Long-term natural history and complications of collagenous colitis.

PubMed

Freeman, Hugh J

2012-09-01

Microscopic forms of colitis have been described, including collagenous colitis, a possibly heterogeneous disorder. Collagenous colitis most often appears to have an entirely benign clinical course that usually responds to limited treatment. Sometimes significant extracolonic disorders, especially arthritis, spondylitis, thyroiditis and skin disorders, such as pyoderma gangrenosum, dominate the clinical course and influence the treatment strategy. However, rare fatalities have been reported and several complications, some severe, have been attributed directly to the colitis. Toxic colitis and toxic megacolon may develop. Concomitant gastric and small intestinal inflammatory disorders have been described including celiac disease and more extensive collagenous inflammatory disease. Colonic ulceration has been associated with the use of nonsteroidal anti-inflammatory drugs, while other forms of inflammatory bowel disease, including ulcerative colitis and Crohn disease, may evolve directly from collagenous colitis. Submucosal 'dissection', colonic fractures, or mucosal tears and perforation, possibly from air insufflation during colonoscopy, have been reported. Similar changes may result from increased intraluminal pressures that may occur during radiological imaging of the colon. Neoplastic disorders of the colon may also occur during the course of collagenous colitis, including colon carcinoma and neuroendocrine tumours (ie, carcinoids). Finally, lymphoproliferative disease has been reported.

Bacterial diseases of the skin.

Edlich, Richard F; Winters, Kathryne L; Britt, L D; Long, William B

2005-01-01

When considering common bacterial diseases of the skin, rather distinct clinical responses to a variety of bacterial infections have been identified. In these cases, it is the specific site of infection and the attendant inflammatory responses that provide the characteristic clinical picture. When the pyoderma extends just below the stratum corneum, it is called impetigo. Nonbullous impetigo is the most common pediatric skin infection. It usually starts in a traumatized area. The typical lesion begins as an erythematous papule, after which it becomes a unilocular vesicle. When the subcorneal vesicle becomes pustular, it ruptures and eventually becomes a yellow, golden crust that is a hallmark of the disease process. Bullous impetigo is a less common form of impetigo, accounting for fewer than 30% of all impetigo cases. It occurs in infants and is characterized by rapid progression of vesicles to the formation of bullae measuring larger than 5 mm in diameter in previously untraumatized skin. Treatment of nonbullous impetigo must include intervention against the pathogen as well as improvements in the hygiene and living conditions of the patient. A fundamental tenet is to debride the crust (scab) from the wound surface using poloxamer 188. If the lesions are not widespread, topical mupirocin is the treatment of choice. Treatment of bullous impetigo is similar, except that the local cleansing and topical antibiotic must be complemented by systemic antibiotics if there is evidence of disseminating infections. Ecthyma is usually a consequence of failure to treat effectively impetigo. The untreated infection extends deep into the tissue in shallow ulcerations that often heal without scar. Treatment for ecthyma usually requires systemic antibiotics against either staphylococcus or streptococcus. Folliculitis is a pyoderma located within a hair follicle, secondary to follicular occlusion by keratin, overhydration, or either bacterial or fungal infection. Folliculitis may be divided into either a deep or a superficial type. In the superficial type, the pustule is located at the opening of the hair follicle. In the deep form, the infection may extend beyond the confines of the hair follicle, becoming a furuncle or boil. Carbuncles are aggregates of interconnected furuncles that drain through multiple openings of the skin. Treatment of folliculitis must include searching for and avoiding any factors predisposing to infection. If topical antibiotic therapy is ineffective in controlling the infection, surgical drainage of the infected skin abscess will be necessary. Paronychia is the most common bacterial infection of the hand, which often requires surgical incisional drainage. Similarly, a felon that is an infection of the distal pulp of a finger usually requires surgical drainage. Finally, cellulitis is an acute inflammatory reaction involving the skin and underlying subcutaneous tissue. It usually starts as erysipelas and may advance to lymphangitis, lymphadenitis, or gangrene,which will respond to life-saving interventions in the hospital that usually include systemic antibiotic treatment as well as surgical intervention.

Periodic fever syndromes are a group of diseases characterized by episodes of fever with healthy intervals between febrile episodes. In the first part of this paper, we presented a guideline for approaching patients with periodic fever and reviewed two common disorders with periodic fever in Iranian patients including familial Mediterranean fever (FMF) and periodic fever syndromes except for periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA). In this part, we review other autoinflammatory disorders including hyper IgD, tumor necrosis factor receptor–associated periodic syndrome (TRAPS), cryopyrin associated periodic syndromes, autoinflammatory bone disorders and some other rare autoinflammatory disorders such as Sweet’s and Blau syndromes. In cryopyrin associated periodic syndromes group, we discussed chronic infantile neurologic cutaneous and articular (CINCA) syndrome, Muckle-Wells syndrome and familial cold autoinflammatory syndrome. Autoinflammatory bone disorders are categorized to monogenic disorders such as pyogenic arthritis, pyoderma ;gangraenosum and acne (PAPA) syndrome, the deficiency of interleukine-1 receptor antagonist (DIRA) and Majeed syndrome and polygenic background or sporadic group such as chronic recurrent multifocal osteomyelitis (CRMO) or synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome are classified in sporadic group. Other autoinflammatory syndromes are rare causes of periodic fever in Iranian system registry. PMID:25562014

Abstract The pathophysiology of neutrophilic dermatoses (NDs) and autoimmune connective tissue diseases (AICTDs) is incompletely understood. The association between NDs and AICTDs is rare; recently, however, a distinctive subset of cutaneous lupus erythematosus (LE, the prototypical AICTD) with neutrophilic histological features has been proposed to be included in the spectrum of lupus. The aim of our study was to test the validity of such a classification. We conducted a monocentric retrospective study of 7028 AICTDs patients. Among these 7028 patients, a skin biopsy was performed in 932 cases with mainly neutrophilic infiltrate on histology in 9 cases. Combining our 9 cases and an exhaustive literature review, pyoderma gangrenosum, Sweet syndrome (n = 49), Sweet-like ND (n = 13), neutrophilic urticarial dermatosis (n = 6), palisaded neutrophilic granulomatous dermatitis (n = 12), and histiocytoid neutrophilic dermatitis (n = 2) were likely to occur both in AICTDs and autoinflammatory diseases. Other NDs were specifically encountered in AICTDs: bullous LE (n = 71), amicrobial pustulosis of the folds (n = 28), autoimmunity-related ND (n = 24), ND resembling erythema gyratum repens (n = 1), and neutrophilic annular erythema (n = 1). The improvement of AICTDS neutrophilic lesions under neutrophil targeting therapy suggests possible common physiopathological pathways between NDs and AICTDs. PMID:25546688

Hypothyroidism in dogs: 66 cases (1987-1992).

PubMed

Panciera, D L

1994-03-01

Sixty-six dogs with hypothyroidism were identified from dogs examined over a 5-year period. Hypothyroidism was diagnosed only if the dog had a low, resting serum thyroxine concentration and serum thyroxine concentration was not higher than the lower limits of the reference range 6 hours after IV administration of bovine thyrotropin. The prevalence of hypothyroidism was 0.2%. Neutering was determined to be the most significant gender-associated risk factor for development of hypothyroidism. Neutered male and spayed female dogs had a higher relative risk of developing hypothyroidism than did sexually intact females. Sexually intact females had a lower relative risk. Breeds with a significantly increased risk, compared with other breeds, were the Doberman Pinscher and Golden Retriever. The most common clinical findings were obesity (41%), seborrhea (39%), alopecia (26%), weakness (21%), lethargy (20%), bradycardia (14%), and pyoderma (11%). Low voltage R-waves were found on 58% of ECG. Clinicopathologic abnormalities included hypercholesterolemia (73%), nonregenerative anemia (32%), high serum alkaline phosphatase activity (30%), and high serum creatine kinase activity (18%). Serum total triiodothyronine concentrations were within reference ranges in 15% of the hypothyroid dogs. Response to treatment was good in most dogs, but those with severe concurrent disease or neurologic abnormalities were less likely to respond with complete resolution of clinical signs.

Skin diseases, especially skin infections, among schoolchildren in Africa can be a major health problem. The objective of this study was to determine the prevalences of skin diseases among children in rural and urban schools in three different African countries and to study the influence of socioeconomic level. Cross-sectional, population-based studies were performed in Ghana, Gabon, and Rwanda. Point prevalences of skin diseases were estimated on the basis of physical examination by at least one dermatologist. A total of 4839 schoolchildren were seen. The overall prevalence of schoolchildren with any skin disease was high and amounted to 34.6% and 42.0% in two Ghanaian studies, 45.8% in Gabon, and 26.7% in Rwanda. In children with skin diseases, skin infections represented the greatest proportion of disease, accounting for 14.7% and 17.6% of skin disease in the Ghanaian studies, and 27.7% and 22.7% in Gabon and Rwanda, respectively. Diseases with the highest prevalence were tinea capitis and bacterial skin infections, especially in rural areas and in schools serving children living at lower socioeconomic levels. The prevalences of skin diseases among African schoolchildren were high. Skin infections such as tinea capitis and pyoderma predominated. © 2013 The International Society of Dermatology.

Cutaneous adverse food reaction (CAFR) is diagnosed by performing an elimination diet trial utilizing prescription or home-cooked diets followed by provocative challenge. To report findings of PCR analysis of a prescription vegetarian diet (RCV) for undeclared proteins of animal origin, as well as to describe its utilization for diagnosis and management of dogs suspected of having CAFR. Three client-owned dogs. PCR analysis of RCV for 11 mammalian species and poultry. In three dogs, clinical examination, cytology, aerobic culture (if indicated) and at least one elimination diet trial with RCV. In our case series, all dogs had a history of pruritus and recurrent pyoderma that resolved with infection control and an elimination diet trial. In cases 1 and 2, a diagnosis of CAFR was made following an elimination trial with RCV and provocative challenge. Case 3 had a previously confirmed diagnosis of CAFR and RCV was successfully used to maintain remission of CAFR-related signs. PCR testing of RCV was negative for 11 mammalian species and poultry. The RCV diet was found not to contain any undeclared mammalian or avian proteins. In this case series, the RCV was successfully used to diagnose and maintain three dogs with CAFR. © 2018 ESVD and ACVD.

Demodex canis is a natural inhabiting mite of canine skin. Immunological disorder or genetic disorder induces the Demodex population to proliferate vigorously resulting in generalized demodicosis with consequent chronic immunosuppression. Signs of generalized demodicosis include alopecia, crysting, erythema, secondary pyoderma etc. Amitraz, an acaricide, is used conventionally for the treatment of generalized demodicosis. In many instances, the disease relapses due to the residual immunosuppression. The need of an immunorestorative therapy has been urged in generalized demodicosis. Two immunorestorative drugs, namely, Immuplus, a herbal drug, and T11TS, a sheep erythrocyte surface glycoprotein, has been used in two separate groups of dogs having generalized demodicosis and receiving Amitraz treatment. It was observed that though Amitraz treated group responded to the therapy showing increased E-rosettes and nonspecific cytotoxic efficacy of T-lymphocytes and decrease in phagocytic potential of macrophages, the groups treated with the immunotherapeutics like Immuplus and T11TS, responded better. However, the group treated with T11TS showed best recovery. These results emphasize the need for an immunorestorative therapy in generalized demodicosis and provide data in favor of T11TS as a better immunomodulator in comparison to Immuplus.

The Staphylococcus (S.) intermedius group (SIG) has been a main research subject in recent years. S. pseudintermedius causes pyoderma and otitis in companion animals as well as foodborne diseases. To prevent SIG-associated infection and disease outbreaks, identification of both staphylococcal exotoxins and staphylococcal cassette chromosome mec (SCCmec) types among SIG isolates may be helpful. In this study, it was found that a single isolate (one out of 178 SIG isolates examined) harbored the canine enterotoxin SEC gene. However, the S. intermedius exfoliative toxin gene was found in 166 SIG isolates although the S. aureus-derived exfoliative toxin genes, such as eta, etb and etd, were not detected. SCCmec typing resulted in classifying one isolate as SCCmec type IV, 41 isolates as type V (including three S. intermedius isolates), and 10 isolates as non-classifiable. Genetic relatedness of all S. pseudintermedius isolates recovered from veterinary staff, companion animals, and hospital environments was determined by pulsed-field gel electrophoresis. Strains having the same band patterns were detected in S. pseudintermedius isolates collected at 13 and 18 months, suggesting possible colonization and/or expansion of a specific S. pseudintermedius strain in a veterinary hospital.

However, the S. intermedius exfoliative toxin gene was found in 166 SIG isolates although the S. aureus-derived exfoliative toxin genes, such as eta, etb and etd, were not detected. SCCmec typing resulted in classifying one isolate as SCCmec type IV, 41 isolates as type V (including three S. intermedius isolates), and 10 isolates as non-classifiable. Genetic relatedness of all S. pseudintermedius isolates recovered from veterinary staff, companion animals, and hospital environments was determined by pulsed-field gel electrophoresis. Strains having the same band patterns were detected in S. pseudintermedius isolates collected at 13 and 18 months, suggesting possible colonization and/or expansion of a specific S. pseudintermedius strain in a veterinary hospital.

Tumor necrosis factor-alpha (TNF)-alpha inhibitors are licensed for patients with severe refractory psoriasis and psoriatic arthritis. However, TNF-alpha inhibitors have also been used off-label for various recalcitrant mucocutaneous diseases. This study aimed to evaluate the efficacy and safety of TNF-alpha inhibitors used for off-label dermatological indications. We retrospectively evaluated patient records of 118 patients treated off-label with TNF-alpha inhibitors in a dermatological university department. Patients presented with severe aphthous stomatitis/genital aphthous lesions (26), chronic urticaria (25), hidradenitis suppurativa (29), acne conglobata (11), dissecting cellulitis of the scalp (two), orofacial granulomatosis (four), sarcoidosis (four), granuloma annulare (two), granulomatous rosacea (one), granuloma faciale (one), subcorneal pustulosis (one), pyoderma gangrenosum (four), Sweet's syndrome (four), Well's syndrome (one), benign familial pemphigus (one), lichen planus (one), and folliculitis decalvans (one). A significant number of these patients went into remission during therapy with TNF-alpha inhibitors. A total of 11 patients (9%) experienced severe adverse effects during therapy. Off-label therapy with TNF-alpha inhibitors may be considered for selected patients with severe recalcitrant mucocutaneous diseases. The risk of severe adverse effects signals that a thorough benefit-risk assessment should be performed before initiating off-label treatment with TNF-alpha inhibitors for these conditions. © 2015 Wiley Periodicals, Inc.

Tinea capitis (TC) is a common fungal infection in children but is less frequently encountered in adults. This study evaluates the clinical characteristics and mycological studies of adult TC among the Egyptian population. A multicenter study included patients diagnosed with TC from 2002 to 2012. The study included 58 patients with a predominance of females (84.5%). The average age was 43.2 years and the mean duration of lesions was 7.1 ± 2.41 months. A history of close contact with animals was reported in 17.2% and Hepatitis C virus infection was recorded in 34.4%. Clinically, scaly scalp (37.9%), alopecia (22.4%), and pyoderma-like lesions (13.8%) were the most common presentations. The parietal (27.6%) and temporal (25.8%) regions were the most affected areas. KOH mounting showed endothrix spores in 56.9%, ectothrix spores in 34.5%, and favic chaplets (hyphae) in 8.6%. Fungal culture showed Trichophyton violaceum in 56.9%, Microsporum audouinii in 19%, Microsporum canis in 15.5%, and Trichophyton schoenleini in 8.6%. Trichophyton violaceum is the most common cause of adult TC among Egyptians. Increased awareness of variable clinical forms of TC will help in identifying more cases, especially those with HCV infection and close contact with animals.

Group A streptococcal infections of the skin: molecular advances but limited therapeutic progress.

PubMed

Currie, Bart J

2006-04-01

With the sequencing of several Streptococcus pyogenes (group A Streptococcus) genomes have come major advances in understanding the pathogenesis of group A Streptococcus-associated diseases. This review focuses on group A Streptococcus skin infections and summarizes data published in the English language medical literature in 2004 and 2005. Group A Streptococcus shows enormous and evolving molecular diversity driven by horizontal transmission between group A Streptococcus strains and between group A Streptococcus and other streptococci. Acquisition of prophages accounts for much of the diversity, conferring both virulence through phage-associated virulence factors and increased bacterial survival against host defences. Studies of group A Streptococcus isolates outside the US also question the generalizability of classic group A Streptococcus M serotype associations with specific disease entities such as acute rheumatic fever and necrotizing fasciitis. The distinction between throat and skin group A Streptococcus has become blurred. Although there have been few advances in treatment of group A Streptococcus skin infections, developments towards group A Streptococcus vaccines are promising. The diversity of group A Streptococcus remains a challenge for vaccine development. As acute rheumatic fever and streptococcal pyoderma occur predominantly in disadvantaged populations, international funding support will be necessary for any group A Streptococcus vaccine to have a sustained impact on the global burden of disease.

AUTOINFLAMMATORY PUSTULAR NEUTROPHILIC DISEASES

SYNOPSIS The inflammatory pustular dermatoses constitute a spectrum of non-infectious conditions ranging from localized involvement to generalized disease with associated acute systemic inflammation and multi-organ involvement. Despite the variability in extent and severity of cutaneous presentation, each of these diseases is characterized by non-infectious neutrophilic intra-epidermal microabscesses. Many share systemic findings including fever, elevated inflammatory markers, inflammatory bowel disease and/or osteoarticular involvement, suggesting potential common pathogenic links (Figure 1). The recent discoveries of several genes responsible for heritable pustular diseases have revealed a distinct link between pustular skin disease and regulation of innate immunity. These genetic advances have led to a deeper exploration of common pathways in pustular skin disease and offer the potential for a new era of biologic therapy which targets these shared pathways. This chapter provides a new categorization of inflammatory pustular dermatoses in the context of recent genetic and biologic insights. We will discuss recently-described monogenic diseases with pustular phenotypes, including deficiency of IL-1 receptor antagonist (DIRA), deficiency of the IL-36 receptor antagonist (DITRA), CARD14-associated pustular psoriasis (CAMPS), and pyogenic arthritis, pyoderma gangrenosum, acne (PAPA). We will then discuss how these new genetic advancements may inform how we view previously described pustular diseases, including pustular psoriasis and its clinical variants, with a focus on historical classification by clinical phenotype.

Serratia marcescens is a species of gram negative bacillus, classified as a member of the Enterobacteriaceae, mainly involved in opportunistic infections, particulary in the hospital environment. Cutaneous infections have rarely reported in literature and are predominantly observed in elderly or in immunocompromised patients. The clinical manifestations of skin infections include granulomatous lesions, necrotizing fasciitis, nodules, cellulitis, ulcers, dermal abscesses. Infections caused by S. marcescens may be difficult to treat because of resistance to a variety of antibiotics, including ampicillin and first and second generation cephalosporins. Aminoglycosides have good activity against S. marcescens, but resistant strains have also been described. We report a very intriguing case of S. marcescens infection, in an immunocompetent 18-year-old man, causing multiple rounded ulcers of varying sizes, along with few pustular lesions that both clinically and histopathologically mimic a pyoderma gangrenosum (PG). This is a non infectious neutrophilic skin disorder, characterized by painful and rapidly progressing skin ulceration. According to our experience, we would strongly recommend to perform cultures of multiple skin ulcers resembling PG, even in young healthy patients, to ensure correct diagnosis and treatment, since resistant to conventional antibiotics bacteria such as S. marcescens may be the cause of these lesions, like in the case here reported.

Dermatology facing autoinflammatory syndrome.

Cutaneous symptoms are characteristic for the autoinflammatory disorders (AIDs), both in the classical autoinflammatory phenotype and in most disorders included in this syndrome, but they are not specific and inconstant. Several skin disorders (pyoderma gangrenosum and pustular acne) may be encountered either isolate or associated with autoinflammatory symptoms, forming well-defined clinical entities within the autoinflammatory syndrome. The high prevalence of cutaneous manifestations is an important characteristic of AIDs. The presence of cutaneous symptoms in AIDs opens the perspective of understanding the contribution of innate immunity mechanisms involved in skin pathology. It is possible that many diseases present the alteration, in various degrees, of the innate immune mechanisms. Recently, dermatology faced two challenges connected to AIDs. The first involves the diagnosis of skin symptoms in a clinical autoinflammatory setting and the investigative approach to identify a disorder classified as AID. The second is to identify the altered mechanisms of inborn immunity among the pathogenetic mechanisms of known dermatological diseases (e.g., neutrophilic dermatoses). On the other hand, cutaneous symptoms are in certain cases regarded as a criterion to asses the efficacy of specific or non-specific therapies with monoclonal antibodies in disorders included in AIDs. Dermatology mostly benefits from the identification and knowledge of AIDs due to the role of innate immunity in skin pathogeny and also due to the large extent of clinical forms resulting from the association of skin symptoms with other disorders included in this group.

Topical antimicrobial preparations are of utmost importance in treating suspected and confirmed meticillin-resistant Staphylococcus pseudintermedius (MRSP) infections due to the increasing incidence of widespread resistance to systemic antimicrobials. Lasalocid is active against MRSP in vitro and this may become an important topical antimicrobial for the treatment of canine pyoderma. To determine effects of various formulation types on penetration and retention of lasalocid applied to canine skin in vitro. Normal canine skin was collected from the thorax of five dogs that had been euthanized on the basis of health and/or intractable behavioural issues. Solution, lotion and ointment containing 2% lasalocid were applied to ex vivo canine skin. Transdermal penetration was assessed for a 24 h period and retention of lasalocid was assessed at the conclusion of the study. The solution had significantly higher skin retention of lasalocid and proportion of applied dose retained in skin than lotion and ointment (Tukey-Kramer Honest Significant Difference test, P < 0.01). Lasalocid could not be detected in the receptor fluid of any Franz cell at any time point. Lasalocid was not identified in the receptor fluid of any sample, indicating that systemic absorption of the active ingredient in vivo is unlikely. Lasalocid may be useful in the treatment of MRSP infections if in vivo studies support safety and efficacy. © 2016 ESVD and ACVD.

Fox Den Disease: An Interesting Case Following Delayed Diagnosis.

Stehr, Ryan C; Kim, Nicholas; LoGiudice, John A; Ludwig, Kirk

2015-06-01

Pyoderma fistulans sinifica, also known as fox den disease, is a rare and poorly understood inflammatory disorder of the skin and subcutaneous tissues. This disorder is often mistaken for other inflammatory skin disorders and treated inappropriately. The authors describe the case of a 53-year-old male who presented to the colorectal surgery service with a longstanding diagnosis of perirectal Crohn's disease. Despite aggressive immunosuppression and numerous surgical procedures, the patient continued to have unrelenting purulent drainage from the skin of his buttocks. Following wide excision of the affected skin and subcutaneous tissues by the colorectal surgeon, the plastic surgery team reconstructed the 30 cm x 55 cm wound using a combination of local flaps and skin grafts. The initial pathology report of the excised specimen confirmed the presence of nonspecific abscesses and inflammation. Upon special request by the plastic surgery team, the sample was resectioned with the specific intent of establishing a diagnosis of fox den disease. The additional slides met the criteria for an unequivocal diagnosis of fox den disease. Immunosuppression was discontinued and the patient healed his wounds without complication. Fox den disease is often overlooked because of the obscurity of the disease and the special histological sectioning needed to establish a diagnosis. In this case, the patient was unnecessarily treated with immunosuppressive drugs for more than 3 decades because of a misdiagnosis. With increased awareness of fox den disease, perhaps its pathophysiology can be better elucidated as more patients are appropriately diagnosed and treated.

[Cutaneous involvement in chronic inflammatory bowel disease : Crohn's disease and ulcerative colitis].

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.

Impact of TNF-α antagonists on the quality of life in selected skin diseases.

Aim of the study was to investigate the impact of TNF-α antagonists on health-related quality of life (HRQoL) in selected skin diseases, i.e. chronic plaque psoriasis, Behçet's disease (BD), hidradenitis suppurativa (HS) and pyoderma gangrenosum (PG). We have carried out a systematic literature search of Medline (2000 to April 2013) using the Cochrane highly sensitive and specific search strategy. Citations were screened for randomized, controlled trials of TNF-α antagonists (adalimumab, etanercept and infliximab) versus placebo in adults with psoriasis, BD, HS or PG. From the literature it is evident that skin diseases can affect physical, psychological, social and occupational aspects of everyday life. TNF-α antagonists induced consistent benefits across health outcomes in psoriasis, but only monoclonal antibodies, infliximab and adalimumab were effective in improving QoL in patients with BD, HS and PG. Dermatology Life Quality Index was the most common used tool for investigating HRQoL. For the majority of patients with skin diseases, the most important negative impacts on QoL were appearance related. Generally, the burden on QoL was correlated to the severity of skin disease and the improvement in QoL achieved by TNF-α blockers was proportional to the degree of disease remission. HRQoL issues are becoming even more important in evaluating medical care, including treatment of skin diseases. In general, achieving the highest clearing of skin disease with anti-TNF-α agents is required for optimal improvement in QoL.

Tinea incognito is a dermatophytic infection in which topical or systemic steroids have modified the clinical appearance of the mycosis and mimicking other skin diseases. A large retrospective study was carried out to identify the clinical aspects and type of dermatophytes involved in tinea incognito cases in Iran during 1993-2008. Out of 6325 subjects suspected to have dermatophytoses, 56 patients (29 males, 27 females, mean age 32.6 years) were affected with tinea incognito. The causative agents were identified macroscopically and microscopically after the clinical samples were subjected to potassium hydroxide examination and culture isolation. The most common type of infection was tinea corporis (32.1%), which significantly affected male patients. The prevalence of the other tineas in decreasing order was as follows: tinea faciei (26.8%), tinea cruris (14.3%), tinea manuum (12.5%), tinea pedis (8.9%), and tinea capitis (5.4%). The clinical features were to some extent diverse, ranging from eczema-like, seborrhoeic dermatitis-like, pyoderma-like and folliculitis to alopecia on scalp, trunk and limbs. Trichophyton verrucosum was the most frequently isolated species representing 33.9% of isolates, followed by T.mentagrophytes (28.6%), T. rubrum (12.5%), Epidermophyton floccosum (10.7%), Microsporum canis (8.9%), T. violaceum (3.6%), and T. schoenleinii (1.8%). To the best of our knowledge, this is the first broad investigation dealing with tinea incognito in Iran. The etiological agents of tinea incognito in Iran are consistent with those of the general population.

Juvenile-Takayasu arteritis (j-TA) is a difficult diagnosis and some patients develop uncommon manifestations and associated diseases that may contribute to the delayed diagnosis. Our aim was to identify the misdiagnoses, the associated diseases and the atypical manifestations observed in a j-TA Brazilian multicentre study. 71 children and adolescents who met the classification criteria for j-TA were included. The misdiagnoses, the associated diseases and the atypical manifestations were evaluated. 19 (26.8%) patients had misdiagnoses. The most common of them was aortic coarctation in six (8.4%) patients, followed by rheumatic fever in five (7.0%) and one patient presented with both former diagnoses. Limb pain (two patients), spondyloarthropathy, juvenile idiopathic arthritis (JIA), spinal arteriovenous malformation, polyarteritis nodosa (PAN) and fever of unknown origin (FUO) were other misdiagnoses. Patients who had misdiagnoses previously to j-TA diagnosis presented a trend to have a longer diagnosis delay. 11 (15.5%) patients had 14 TA-associated diseases, such as pulmonary tuberculosis (5 patients), rheumatic fever (2 patients), spondyloarthropathy, polyarticular JIA, Crohn's disease, Prader-Willi disease, diabetes mellitus, Moyamoya and primary immunodeficiency. 7 (9.9%) patients presented 10 atypical manifestations, such as pyoderma gangrenosum, erythema nodosum, myositis, chorea, enthesitis, episcleritis, uveitis, hepatomegaly, splenomegaly and necrosis of extremities. Our study emphasizes the main misdiagnoses, associated diseases and atypical manifestations that occur in patients with j-TA and warns of the features that may alert paediatricians to this diagnosis, such as constitutional symptoms and elevated inflammatory markers.

Background: ‘Holi’ is an annual spring festival celebrated all over India. The central ritual of Holi involves throwing of colors on one another. Playing with toxic industrial dyes often results in various dermatological complaints in a significant number of people immediately following the celebration. Aims: To describe patterns of various skin manifestations directly or indirectly related to the use of different colors in the celebration of Holi. Methods: Observational clinical study on consecutive patients presenting to a teaching hospital in Kolkata, India. Results: Forty-two patients with a mean age of 24.2 years were studied. Itching was the commonest symptom (25, 59.5%), followed by burning sensation, pain, oozing, and scaling. Eleven patients’ symptoms were attributed to activities related to preparation of colors and the removal of colors from the skin surface. Eczematous lesions were the most common pattern (24, 57.1%) followed by erosions, xerosis and scaling, erythema, urticaria, acute nail-fold inflammation, and abrasions. Thirteen (30.9%) patients reported aggravation of preexisting dermatoses (acne, eczema, and paronychia). Secondary pyoderma occurred in 3 (7.1%). Face was the commonest site affected (24, 57.1%), followed by dorsum of the hands, scalp, forearm, palms, arms, and trunk. Ocular complaints in the form of redness, watering, and grittiness occurred in 7 (16.7%) patients. Conclusion: Various forms of cutaneous manifestations, often associated with ocular complaints, occur commonly due to Holi colors. Public awareness and regulatory actions are needed to avoid these preventable conditions. PMID:20161854

To describe a case of feline sebaceous adenitis and mural folliculitis, and its successful treatment with topical fatty acids. A 5-year-old, male castrated Norwegian Forest cat was presented with a progressive seborrhoeic dermatitis. Clinical examination and histopathological examination of skin biopsies. There was severe, multifocal, lymphocytic mural folliculitis and perifollicular dermatitis, moderate hyperkeratosis and sebaceous adenitis on histopathology. Sebaceous glands were either absent or almost completely effaced by a dense lymphocytic infiltrate. Clinical signs began in spring on the face and neck and progressed over an 18 month period to involve the legs. Initially, topical and systemic antibacterial therapy for a mild bacterial overgrowth resulted in partial clinical response. There was no improvement with oral omega 6 fatty acids and surface cleaning. Treatment with a spot-on product containing essential oils, smoothing agents and vitamin E as the sole therapy was associated with a good--but incomplete--clinical response over a 6 month period, with hair regrowth and a marked decrease in seborrhoeic dermatitis. This improvement was sustained until 12 months later when a severe deep pyoderma with associated anorexia and depression occurred. This was symptomatically treated and the cat remained clinically stable for a further 18 months. Periocular and perinasal seborrhoea was a persistent feature. Topical essential fatty acid therapy may offer a viable alternative to ciclosporin, which has been reported for the successful treatment of this rare disease in cats. © 2015 ESVD and ACVD.

A 50-year-old Japanese woman consulted the emergency department of our hospital for bleeding due to an intractable postoperative wound on the lower abdomen; the postoperative wound was owing to a laparoscopic cholecystectomy performed 1 year previously for acute cholecystitis. She presented with a painful ulcer on her right lower abdomen. She also presented with multiple scars, skin grafts on the extremities, and a missing left lower leg, the causes for all of which were unexplained. The results of her blood test were normal, except for the hemoglobin level. Histology of the skin biopsy specimen from the ulcer did not show any specific findings. The previous surgeon who had performed the laparoscopic cholecystectomy revealed that surgical wound dehiscence had occurred during her admission. After a body restraint had been applied, the ulcer improved. Medical records indicated that she had been admitted to the department of plastic surgery at our hospital for skin grafting of a leg ulcer. During that admission, she refused to consult with the department of psychiatry, al-though the staff suspected mental disorders. Therefore, we diagnosed her with cutaneous Munchausen syndrome. After vacuum-assisted closure (VAC) therapy had been performed to prevent her from traumatizing the ulcer again, it rapidly became granulated and reepithelialized. Munchausen syndrome is characterized by feigning physical symptoms to seek attention. Patients self-inflict numerous lesions, keep getting admitted to different hospitals, and feign acute illness, usually spectacular diseases. VAC therapy may be effective for preventing patients with cutaneous Munchausen syndrome from traumatizing their wounds. PMID:27194978

2011-05-01

The goal of this study was to estimate the health and economic consequences of non-compliance with oral antimicrobial treatment in dogs with superficial pyoderma, wounds or abscesses in the US. A mathematical model (Markov model) which simulated treatment with long-term injectable cefovecin versus oral amoxicillin/clavulanic acid was developed and accounted for the effect of non-compliance on clinical outcomes and mean total treatment costs per patient. Efficacy parameters considered in the model were derived from clinical studies. Treatment failure due to oral antimicrobial treatment non-compliance was approximated from published data at 13.6%. US cost data for 2009 were derived from public sources. When non-compliance was considered as a cause of treatment failure with oral medication, the long-term injectable antibiotic was more effective than oral comparator (162 versus 158 days without clinical signs). Mean total treatment costs were lower with cefovecin (USD 376.74) versus amoxicillin/clavulanic acid (USD 382.34) in dogs of 25 kg; and cefovecin remained cost-saving up to a body weight of 31 kg. In large dogs, cefovecin was more costly; however, total therapy costs were less than 6% greater than with amoxicillin/clavulanic acid. Accordingly the higher drug and administration costs of the long-term injectable antibiotic were totally or substantially offset when non-compliance was considered as reason for treatment failure with oral medication. The model also allowed for the estimation of the impact of various non-compliance scenarios. Copyright © 2011 Elsevier B.V. All rights reserved.

Skin rash and arthritis a simplified appraisal of less common associations.

Cozzi, A; Doria, A; Gisondi, P; Girolomoni, G

2014-06-01

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.

Atypical ulcers: wound biopsy results from a university wound pathology service .

2012-06-01

Chronic wounds are an increasing health burden across the continuum of care and encountered by a wide variety of healthcare providers and physicians of all specialties. The majority of chronic wounds are caused by vascular insufficiency, neuropathy, or prolonged pressure. Wounds caused by other underlying health conditions or external factors such as radiation or spider bites are usually referred to as atypical. Although a wound biopsy generally is recommended in the case of refractory, nonhealing ulcers or when wounds present with atypical signs and symptoms, little is known about the distribution of atypical ulcers. A retrospective, descriptive study was conducted to describe the proportion and differential diagnosis of atypical ulcer biopsies received during a 2-year period by the wound pathology division in the division of Dermatopathology at the University of Miami Department of Dermatology and Cutaneous Surgery. Of the 350 wound biopsies received for diagnostic purposes, 104 (29.7%) were due to atypical causes. The majority of specimens were neoplasms (n = 24). Pyoderma gangrenosum was the most common atypical diagnosis encountered (n = 14). Vasculitis, predominantly leukocytoclastic vasculitis, and external causes were diagnosed in 16 and 15 biopsies, respectively. This study represents the first published case series of atypical ulcer biopsy results from a wound pathology division. Although the prevalence results cannot be generalized and are likely lower in the general population of patients with nonhealing wounds, the results confirm the usefulness of obtaining wound biopsies to provide a definitive diagnosis and to guide care.

To describe and compare clinical and cytological features and bacterial culture results from the lower lips of dogs with cheilitis (as compared to healthy controls), and to evaluate three cytology sampling techniques for their abilities to differentiate between the groups. Fifty six dogs with cheilitis and 54 controls. Anatomy and clinical signs of the lower lip were recorded. Cytology samples taken by tape strip, direct impression and swabs rolled over skin were scored semiquantitatively for microorganisms, inflammatory cells and keratinocytes. Cytology scores were correlated with semiquantitative bacterial culture scores. Pure breeds, frequency of lip folds and all cytology scores except keratinocytes were higher in dogs with cheilitis than in controls, but a substantial overlap was seen in all microorganisms between the groups. Hypersensitivity disorders were diagnosed in 40 of 56 dogs with cheilitis. The tape strip technique yielded the greatest differences between groups. Bacterial growth was reported in 100% of dogs with cheilitis and in 93% of the controls. Pathogens such as Staphylococcus pseudintermedius, Escherichia coli and Pseudomonas spp were found more frequently in dogs with cheilitis. Cytology and bacterial culture were poorly correlated. Cheilitis was associated with primary hypersensitivity disorders and the presence of a lip fold was a predisposing factor. Results of aerobic culture were similar to prior studies on pyoderma of other body sites, except for higher rates of Pseudomonas spp. isolation. © 2016 ESVD and ACVD.

Human scabies is a major global public health issue, with an estimated 300 million cases per year worldwide. Prevalence rates are particularly high in many third-world regions and within various indigenous communities in developed countries. Infestation with Sarcoptes Scabiei is associated with group-A streptococcal pyoderma which in turn predisposes to rheumatic fever, acute glomerulonephritis and their respective long-term sequelae: rheumatic heart disease and chronic renal insufficiency. The documented difficulties inherent in achieving scabies control within affected communities have motivated us to develop a network-dependent Monte-Carlo model of the scabies contagion, with the dual aims of gaining insight into its dynamics, and in determining the effects of various treatment strategies. Here we show that scabies burden is adversely affected by increases in average network degree, prominent network clustering, and by a person-to-person transmissibility of greater magnitude. We demonstrate that creating a community-specific model allows for the determination of an effective treatment protocol that can satisfy any pre-defined target prevalence. We find frequent low-density treatment protocols are inherently advantageous in comparison with infrequent mass screening and treatment regimes: prevalence rates are lower when compared with protocols that administer the same number of treatments over a given time interval less frequently, and frequent low-density treatment protocols have economic, practical and public acceptance advantages that may facilitate their long-term implementation. This work demonstrates the importance of stochasticity, community structure and the heterogeneity of individuals in influencing the dynamics of the human scabies contagion, and provides a practical method for investigating the outcomes of various intervention strategies.

Introduction Various dermatoses, due to their morbidity characteristics, have been shown to negatively impact on learning. The most epidemiologically important seem to be the infectious types because of their transmissibility and amenability to simple school-health measures. The aim of this study was to assess the prevalence and sex/age correlates of infectious dermatoses in a rural South-eastern Nigerian community. Methods The pupils were proportionately recruited from the three primary schools based on school population. Stratified simple random sampling method was adopted and a table of random numbers was used to select required pupils from each arm. Clinical and laboratory examination was done to establish diagnoses of infectious skin disease. Data collected were analyzed using SPSS version 16. Results The 400 pupils consisted of 153 males and 247 females. Age range was between 6 and 12 years. The prevalence of infectious dermatoses was 72.3%. The five most prevalent clinical forms of infectious dermatoses, in order of decreasing prevalence, were tinea capitis (35.2%), scabies (10.5%), tinea corporis (5.8%), tinea pedis (5.5%), and impetigo (5.0%). More cases, generally, occurred among males than females (80.4% vs 67.2%)); while some specific clinical types, pediculosis and seborrheic dermatitis, exhibited predilection for females. Pyodermas and scabies were significantly more prevalent in the 7-9 age-group; while tinea capitis, tinea corporis, seborrheic dermatitis and pediculosis were more associated with ≥10 age-group. Conclusion Infectious dermatoses were highly prevalent in the surveyed population. Many of the clinical types exhibited sex- and age-specificity. PMID:26430479

A vascular cause is found in around 85% of leg ulcer patients, but non-vascular causes are also observed. Their diagnosis is based on a set of clinical arguments and skin biopsy with histological analysis. The aim of this study was to analyze the results of these biopsies and to find common criteria for ulcers whose skin biopsies had led to the diagnosis of a non-vascular ulcer. A retrospective study was carried out on the analysis of 143 skin biopsies of leg ulcers. The reasons for the biopsy were mainly atypical clinical signs and/or the lack of improvement in care after 6 months, as advocated by the French health authorities. The skin biopsies led to a diagnosis of non-vascular ulcer in 4.9% of cases (7/143), including skin cancer (n=5, 3.5%), cutaneous leishmaniasis (n=1, 0.7%) and Pyoderma gangrenosum (n=1, 0.7%). The univariate statistical analysis revealed that an elevated rim and abnormal excessive granulation tissue were significantly more frequently found in these ulcers. All patients with a positive skin biopsy had associated vascular involvement. This study found a 5% rate of non-vascular causes of ulcers, mainly skin cancer. Elevated rims and abnormal excessive granulation tissue were the unusual features most commonly found in these ulcers. All patients whose skin biopsy revealed a non-vascular cause had associated vascular involvement. This information confirms the need to perform a skin biopsy, even in the presence of a vascular disease. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Problems in Diagnosing Scabies, a Global Disease in Human and Animal Populations

PubMed Central

Walton, Shelley F.; Currie, Bart J.

Scabies is a worldwide disease and a major public health problem in many developing countries, related primarily to poverty and overcrowding. In remote Aboriginal communities in northern Australia, prevalences of up to 50% among children have been described, despite the availability of effective chemotherapy. Sarcoptic mange is also an important veterinary disease engendering significant morbidity and mortality in wild, domestic, and farmed animals. Scabies is caused by the ectoparasitic mite Sarcoptes scabiei burrowing into the host epidermis. Clinical symptoms include intensely itchy lesions that often are a precursor to secondary bacterial pyoderma, septicemia, and, in humans, poststreptococcal glomerulonephritis. Although diagnosed scabies cases can be successfully treated, the rash of the primary infestation takes 4 to 6 weeks to develop, and thus, transmission to others often occurs prior to therapy. In humans, the symptoms of scabies infestations can mimic other dermatological skin diseases, and traditional tests to diagnose scabies are less than 50% accurate. To aid early identification of disease and thus treatment, a simple, cheap, sensitive, and specific test for routine diagnosis of active scabies is essential. Recent developments leading to the expression and purification of S. scabiei recombinant antigens have identified a number of molecules with diagnostic potential, and current studies include the investigation and assessment of the accuracy of these recombinant proteins in identifying antibodies in individuals with active scabies and in differentiating those with past exposure. Early identification of disease will enable selective treatment of those affected, reduce transmission and the requirement for mass treatment, limit the potential for escalating mite resistance, and provide another means of controlling scabies in populations in areas of endemicity.

A 5-year-old neutered male Mastiff and an 8-year-old spayed female Labrador Retriever were presented to the University of Minnesota Veterinary Medical Center. The Mastiff was presented for evaluation of lameness and pyoderma one month prior in Missouri, where he tested positive for Ehrlichia canis by serum ELISA test, treated with doxycycline. PCR for Ehrlichia sp, Anaplasma sp, Babesia sp, and Bartonella sp, and PCR for antigen receptor rearrangement were negative, serum protein electrophoresis (SPE) revealed polyclonal gammopathy, and mildly reactive lymphoid cells were seen cytologically. The Labrador presented with a proliferative rostral mandibular gingival mass and lipomas for further presurgical evaluation of cold agglutinin activity documented by a commercial laboratory 2 years earlier prior to removal of a grade II mast cell tumor. This dog had a negative SNAP4Dx, normal SPE, and persistently increased serum ALP activity and polyuria/polydipsia suggestive for hyperadrenocorticism. Both dogs had markedly agglutinated RBC in the EDTA samples that dispersed with warming, and normal plasma color. Cold agglutinin activity was demonstrated by direct saline agglutination testing using whole blood and washed erythrocytes demonstrating agglutination at 30°C, 25°C, 15°C, and 4°C, but not at 37°C. CBC results (ADVIA 2120i) from the Mastiff revealed no significant differences in the RBC results obtained at room temperature (RT) and at 37°C; however, the RT run demonstrated negative bias in neutrophil and platelet concentrations attributed to rapid RBC settling. This uncommon hematologic condition may cause artifacts on the automated leukogram and platelet count, and may be subclinical for long periods. © 2014 American Society for Veterinary Clinical Pathology and European Society for Veterinary Clinical Pathology.

Fungal infections of the skin are a common condition, usually easy to diagnose and treat. When the infection is clinically mimicking another cutaneous disorder or when the clinical presentation is modified by the use of inappropriate treatment, it is referred to as tinea atypica or tinea incognito.We report a series of nine cases of patients with tinea atypica, imitating and diagnosed initially as different skin diseases. Two patients were defined as pyoderma in the facial and pubic regions (caused respectively by Trichophyton mentagrophytes var. mentagrophytes and Microsporum canis) and one as herpes zoster ophthalmicus (caused by Trichophyton rubrum). Six additional patients were initially misdiagnosed: (1) Plaque-like formation of the skin misdiagnosed as an impetiginized eczema (with isolated agent Trichophyton verrucosum). (2) A rare form of skin infection of the hand caused by T. rubrum, imitating clinically cutaneous infection with tuberculum mulgentium. (3) Rosacea-like dermatitis with an isolated agent Fusarium. (4) A patient with the typical clinical symptoms of seborrheic dermatitis of the face (and with isolated T. rubrum as a causative agent). (5) Another patient presented with a widespread folliculitis by Trichophyton mentagrophytes. (6) In a patient with bullous pemphigoid and immunosuppression pemphigoid-like eruptions were caused by Malassezia pachydermatis and T. rubrum. The diagnosis in the presented cases was based on direct microscopic examination with KOH and a culture on Sabouraud agar.After the diagnosis of tinea, treatment with topical and systemic antifungal agents was administrated, followed by complete clinical remissions in all cases.The clinical manifestations of tinea atypica can mimic a large number of other dermatoses, which often leads to misdiagnosing, and as a consequence--to serious difficulties in the management of clinical symptoms and in offering appropriate therapy.

Atopic dermatitis (AD) is a common skin disease encountered in both humans and dogs. Canine AD can be used in the analysis of naturally occurring AD; however, details of clinical comparison have been lacking. The purpose of this study is to compare those clinical features using the human diagnostic criteria (Japanese Dermatological Association, 2009). Fifty-one dogs with canine AD were evaluated by the human criteria. Prior to this study, canine AD was basically diagnosed by the fulfillment of two authentic canine AD criteria and a positive reaction against Dermatophagoides farinae in serum immunoglobulin E levels and/or in intradermal tests. Among the human AD criteria items, behavior corresponding to pruritus was observed in all 51 dogs. Skin lesions corresponding to eczematous dermatitis were seen in 50 dogs, and symmetrical distribution of skin lesions was noted in all 51 dogs. A chronic or chronically relapsing course was observed in 50 dogs. Based on these results, the concordance rate for the criteria was 96% (49/51). Differential diagnoses of AD were also investigated in the same manner. The concordance rate for the criteria was 0% (0/69) in scabies, 2% (1/50) in pyoderma, 0% (0/50) in demodicosis, 0% (0/9) in cutaneous lymphoma, 0% (0/2) in ichthyosis, 25% (2/7) in flea allergy, 48% (24/50) in seborrheic dermatitis and 75% (3/4) in food allergy. Canine AD is thus indicated as a valuable counterpart to human AD in clinical aspects. In addition, the human AD criteria could be applicable, with some modification, as provisional diagnostic criteria for canine AD. © 2011 Japanese Dermatological Association.

The objective of this study was to describe the occurrence of skin infection associated hospitalizations in children born in Western Australia (WA). We conducted a retrospective cohort study of all children born in WA between 1996 and 2012 (n = 469,589). Of these, 31,348 (6.7%) were Aboriginal and 240,237 (51.2%) were boys. We report the annual age-specific hospital admission rates by geographical location and diagnostic category. We applied log-linear regression modelling to analyse changes in temporal trends of hospitalizations. Hospitalization rates for skin infections in Aboriginal children (31.7/1000 child-years; 95% confidence interval [CI] 31.0-32.4) were 15.0 times higher (95% CI 14.5-15.5; P<0.001) than those of non-Aboriginal children (2.1/1000 child-years; 95% CI 2.0-2.1). Most admissions in Aboriginal children were due to abscess, cellulitis and scabies (84.3%), while impetigo and pyoderma were the predominant causes in non-Aboriginal children (97.7%). Admissions declined with age, with the highest rates for all skin infections observed in infants. Admissions increased with remoteness. Multiple admissions were more common in Aboriginal children. Excess admissions in Aboriginal children were observed during the wet season in the Kimberley and during summer in metropolitan areas. Our study findings show that skin infections are a significant cause of severe disease, requiring hospitalization in Western Australian children, with Aboriginal children at a particularly high risk. Improved community-level prevention of skin infections and the provision of effective primary care are crucial in reducing the burden of skin infection associated hospitalizations. The contribution of sociodemographic and environmental risk factors warrant further investigation.

Atopic dermatitis (AD) is recognized as a common cause of pruritus in cats, but it remains incompletely characterized. The aim of the study was to evaluate cases of confirmed feline AD. Fourty-five cats from a dermatology referral practice (2001-2012). A retrospective case record review was carried out using strict diagnostic criteria, including exclusion of flea-bite hypersensitivity and adverse food reaction. Disease prevalence was 12.5%, with domestic mixed (n = 24), Abyssinian (n = 6) and Devon rex (n = 3) cat breeds predisposed. Median age of onset was 2 years (62% <3 years; 22% >7 years; range 3 months to 12 years). Common presentations were severe (82%), nonseasonal (82%), waxing/waning (36%) pruritus, with alopecia/crusting/excoriations and/or erosions/ulceration (73%). Miliary dermatitis (20%) and eosinophilic granuloma complex lesions (27%) occurred. The face/head (71%), ventral abdomen (51%), neck (51%), limbs (38%), pinnae (31%), dorsum/rump (31%) and feet (16%) were frequently affected sites; lesions were restricted to the head/neck in only five cats (11%). Concurrent otitis externa (16%), superficial bacterial pyoderma (49%), Malassezia dermatitis (7%), flea-bite hypersensitivity (24%) and adverse food reaction (13%) occurred. Strong reactions on intradermal allergen testing were common (68%; 19 of 30), most frequently to pollens (61%) and/or insects (46%). Good response to ciclosporin (100%; 10 of 10), systemic glucocorticoids (55%; 22 of 40) and allergen-specific immunotherapy (57%; 13 of 23) and good/partial response to antihistamines (67%; 22 of 33) were reported. The prevalence of feline AD was higher than previously suggested, and breed predispositions were confirmed. Severe nonseasonal pruritus was most common, with a varied spectrum of lesions affecting a range of body areas. © 2014 ESVD and ACVD.

Meticillin-resistant (MR) staphylococcal pyoderma in dogs has led to increased use of alternate antibiotics such as rifampicin (RFP). However, little information exists regarding its pharmacodynamics in MR Staphylococcus pseudintermedius. To determine the minimum inhibitory concentration (MIC) and killing properties of RFP for canine Staphylococcus pseudintermedius isolates. The MIC of RFP was determined using the ETEST ® for 50 meticillin-susceptible (MS) and 50 MR S. pseudintermedius isolates collected from dogs. From these isolates, two MS isolates (RFP MIC of 0.003 and 0.008 μg/mL, respectively) and two MR isolates (RFP MIC of 0.003 and 0.012 μg/mL, respectively) were subjected to time-kill studies. Mueller-Hinton broth was supplemented with RFP at 0, 0.5, 1, 2, 4, 8, 16 and 32 times the MIC for 0, 2, 4, 10, 16 and 24 h. The number of viable colony forming units in each sample was determined using a commercial luciferase assay kit. The MIC 50 and MIC 90 were the same for MS and MR isolates, at 0.004 μg/mL and 0.008 μg/mL, respectively. Rifampicin kill curves were not indicative of concentration-dependency, suggesting time-dependent activity. Two isolates (MS 0.003 and 0.008 μg/mL) exhibited bacteriostatic activity, whereas two others (MR 0.003 and 0.012 μg/mL) exhibited bactericidal activity. This study demonstrated that MS and MR S. pseudintermedius isolates were equally susceptible to rifampicin and that dosing intervals should be designed for time-dependent efficacy. These data can support pharmacokinetic studies of RFP in dogs with susceptible infections caused by S. pseudintermedius. © 2018 ESVD and ACVD.

Staphylococcus pseudintermedius and Malassezia pachydermatis are important agents in canine pyoderma and otitis. Determine the in vitro efficacy of a honey-based gel (HBO) against meticillin-susceptible S. pseudintermedius (MSSP), meticillin-resistant S. pseudintermedius (MRSP) and M. pachydermatis, by minimum bactericidal concentration (MBC), minimum fungicidal concentration (MFC) and time-kill assay (TKA). Efficacy of the product's honey component (HO) also was evaluated. Sixty S. pseudintermedius and 10 M. pachydermatis canine isolates were selected. All isolates were tested against serial dilutions of an HBO containing 40% HO (40%, 20%, 10%, 5% and 2.5% w/v) and HO alone (undiluted, 40%, 20%, 10%, 5% and 2.5% w/v). Microbroth assay followed by subculture was used to determine MBC and MFC. The same protocol was applied after product exposure to catalase. A well-diffusion assay for S. pseudintermedius was used to generate inhibition zones. A TKA for 10 isolates of S. pseudintermedius and 10 isolates of M. pachydermatis was performed. MBC was 20% w/v (5-20% w/v) for HBO and HO. HBO had lower MBC values when compared to HO (P = 0.003). No statistical difference was observed between MSSP/MRSP isolates (HBO P = 0.757, HO P = 0.743). Only HO was affected by catalase (P = 0.015). MFC for HBO was 10% w/v (5-10% w/v) and 40% w/v for HO (20-≥40% w/v). All isolates were killed after 4 h of exposure. Staphylococcus pseudintermedius and M. pachydermatis are susceptible to the HBO and these results can be used for future clinical trials. © 2018 ESVD and ACVD.

AIM To investigate whether immune mediated diseases (IMD) are more frequent in patients with inflammatory bowel disease (IBD). METHODS In this population based registry study, a total of 47325 patients with IBD were alive and registered in the Danish National Patient Registry on December 16, 2013. Controls were randomly selected from the Danish Civil Registration System (CRS) and matched for sex, age, and municipality. We used ICD 10 codes to identify the diagnoses of the included patients. The IBD population was divided into three subgroups: Ulcerative colitis (UC), Crohn’s disease (CD) and Both the latter referring to those registered with both diagnoses. Subsequently, odds-ratios (OR) and 95%CI were obtained separately for each group and their respective controls. The use of Bonferoni post-test correction adjusted the significance level to P < 0.00125. P-values were estimated using Fisher’s exact test. RESULTS There were significantly more women than men in the registry, and a greater percentage of comorbidity in the IBD groups (P < 0.05). Twenty different IMDs were all significantly more frequent in the IBD group. Sixteen were associated with UC versus twelve with CD. In both UC and CD ORs were significantly increased (P < 0.00125) for primary sclerosing cholangitis (PSC), celiac disease, type 1 diabetes (T1D), sarcoidosis, asthma, iridocyclitis, psoriasis, pyoderma gangrenosum, rheumatoid arthritis, and ankylosing spondylitis. Restricted to UC (P < 0.00125) were autoimmune hepatitis, primary biliary cholangitis, Grave’s disease, polymyalgia rheumatica, temporal arteritis , and atrophic gastritis. Restricted to CD (P < 0.00125) were psoriatic arthritis and episcleritis. Restricted to women with UC (P < 0.00125) were atrophic gastritis, rheumatoid arthritis, temporal arteritis, and polymyalgia rheumatica. Restricted to women with CD were episcleritis, rheumatoid arthritis, and psoriatic arthritis. The only disease restricted to men (P < 0.00125) was sarcoidosis. CONCLUSION Immune mediated diseases were significantly more frequent in patients with IBD. Our results strengthen the hypothesis that some IMDs and IBD may have overlapping pathogenic pathways.

To determine the prevalence of immune-mediated inflammatory diseases (IMID) in a cohort of patients with inflammatory bowel disease (IBD) enrolled in hospital gastroenterology outpatients units for the AQUILES study, a prospective 2-year follow-up study. We included patients ≥18 years old with a prior or new diagnosis of IBD (Crohn disease [CD], ulcerative colitis [UC] or indeterminate colitis). Diagnoses were collected in a cross-sectional manner from the clinical records at enrollment of a new patient in the study. We included 526 patients (mean age 40.2 years; 47.3% men, 52.7% women), 300 with CD (57.0%), 218 with UC (41.4%) and 8 with indeterminate colitis. Other types of IMID were present in 71 patients (prevalence: 13.5%, 95% CI: 10.8-16.7): 47 were spondyloarthropathies (prevalence: 8.9%); 18 psoriasis (3.4%); 5 pyoderma gangrenosum (1.0%), and 11 uveitis (2.1%). The prevalence of IMID was higher in patients with CD than in those with UC (17.0% [95% CI: 13.2-21.7] vs 9.2% [95% CI: 6.0-13.8], p=0.011). In the multivariate analysis, the variables associated with the presence of IMID were diagnosis of CD (OR=1.8 [95% CI: 1.1-3.2]) and duration of IBD ≥4 years (OR=2.1 [95% CI: 1.1-4.1] in those with disease duration 4-8 years, and OR=2.1 [95% CI: 1.2-3.9] in those with ≥8 years vs. <4 years). In the cohort of patients with IBD in the AQUILES study, 13.5% had another IMID, with a higher prevalence in patients with CD and>4 years since disease onset.

The recent interest and elucidation of the JAK/STAT signaling pathway created new targets for the treatment of inflammatory skin diseases (ISDs). JAK inhibitors in oral and topical formulations have shown beneficial results in psoriasis and alopecia areata. Patients suffering from other ISDs might also benefit from JAK inhibition. Given the development of specific JAK inhibitors, the expression patterns of JAKs in different ISDs needs to be clarified. We aimed to analyze the expression of JAK/STAT family members in a set of prevalent ISDs: psoriasis, lichen planus (LP), cutaneous lupus erythematosus (CLE), atopic dermatitis (AD), pyoderma gangrenosum (PG) and alopecia areata (AA) versus healthy controls for (p)JAK1, (p)JAK2, (p)JAK3, (p)TYK2, pSTAT1, pSTAT2 and pSTAT3. The epidermis carried in all ISDs, except for CLE, a strong JAK3 signature. The dermal infiltrate showed a more diverse expression pattern. JAK1, JAK2 and JAK3 were significantly overexpressed in PG and AD suggesting the need for pan-JAK inhibitors. In contrast, psoriasis and LP showed only JAK1 and JAK3 upregulation, while AA and CLE were characterized by a single dermal JAK signal (pJAK3 and pJAK1, respectively). This indicates that the latter diseases may benefit from more targeted JAK inhibitors. Our in vitro keratinocyte psoriasis model displayed reversal of the psoriatic JAK profile following tofacitinib treatment. This direct interaction with keratinocytes may decrease the need for deep skin penetration of topical JAK inhibitors in order to exert its effects on dermal immune cells. In conclusion, these results point to the important contribution of the JAK/STAT pathway in several ISDs. Considering the epidermal JAK3 expression levels, great interest should go to the investigation of topical JAK3 inhibitors as therapeutic option of ISDs.

Pyogenic Arthritis, Pyoderma gangrenosum, and Acne (PAPA syndrome) is a rare autosomal dominant, auto-inflammatory disease that affects joints and skin. The disease results due to mutations in the cluster of differentiation 2 binding protein 1 (CD2BP1) gene on chromosome 15q24.3. Rheumatoid arthritis (RA) is a common, genetically complex disease that affects the joints with occasional skin manifestations. Studies related to the pathophysiology of inflammation in these two disorders show a certain degree of overlap at genetic level. The present study was done to confirm the existence of such a genetic overlap between PAPA syndrome and RA in south Indian population. In the present study 100 patients who were clinically diagnosed rheumatoid arthritis and 100 apparently healthy controls were chosen and the 15 exons of CD2BP1 gene were PCR-amplified and sequenced. The sequence analysis showed that in exon 3 thirty eight patients revealed presence of novel heterozygous missense mutations p.Glu51Asp, p.Leu57Arg and p.Ala64Thr. In exons 6, 10 and 14 eight patients showed 44 novel missense mutations and two patients showed novel frame shift mutations p.(Met123_Leu416delinsThr) and p.(Thr337Profs*52) leading to truncated protein formation. Such mutations were not seen in controls. Further, the in silico analysis revealed the mutant CD2BP1 structure showed deletion of Cdc15 and SH3 domains when superimposed with the wild type CD2BP1 structure with variable RMSD values. Therefore, these structural variations in CD2BP1 gene due to the mutations could be one of the strongest reasons to demonstrate the involvement of these gene variations in the patients with rheumatoid arthritis.

Summary Studies on Staphylococcus aureus and Staphylococcus intermedius from dog and cat, and also on Staphylococcus aureus from wound and pyoderma infections, have shown a correlation between the site of microbial infection and antimicrobial susceptibility. Both the methanolic extract concentrate of Garcinia kola (Heckel) seeds and natural honey have been associated with activity on bacterial isolates from respiratory tract infections. In this study, selected bacteria belonging to genera from burn wound infection sites were treated with natural honey and methanolic extract concentrate of Garcinia kola in antimicrobial susceptibility tests separately and in combined form, and also with gentamicin and methanol as controls. The two natural products were found to be active on the bacterial isolates, excluding Klebsiella pneumoniae strains, all of which showed resistance to honey. Combination forms of the two natural products were active only on the strains of Pseudomonas aeruginosa. At 4 and 8 µg/ml, gentamicin was ineffective on the three strains of Klebsiella pneumoniae while 8 µg/ml was moderately active on only two strains of Pseudomonas aeruginosa. One strain of Pseudomonas aeruginosa, UCH002, was resistant to gentamicin beyond 1,000 µ/ml. Gentamicin at 4 µ/ml was inhibitory to one strain of Escherichia coli and two strains of Staphylococcus aureus. Though the antimicrobial activity of the two natural products tested had been previously reported against microbial agents of respiratory tract infection, it was also recorded in this study. The lack of activity of each of the three honey types used in this study against the Klebsiella pneumoniae strains tested underscores the need to exclude this organism from burn wound infections before embarking on treatment with honey. The sensitivity of one high-level gentamicin-resistant strain of Pseudomonas aeruginosa to honey and Garcinia kola seed extract was noteworthy considering the therapeutic failures of gentamicin and other antibiotics against Pseudomonas aeruginosa.

The records of 15 dogs diagnosed as having juvenile cellulitis (juvenile pyoderma, puppy strangles) were evaluated for clinical, laboratory, and therapeutic results. Mandibular lymphadenopathy was observed in 14 dogs, and was not associated with skin lesions in 5 dogs. Edema, pustules, papules, or crusts were noticed periorally, periocularly, on the chin or muzzle, or in the ears of those dogs with skin lesions. Eight dogs were lethargic; fever and anorexia were inconsistent findings. Four dogs had signs of pain on manipulation of their joints. Complete blood counts revealed leukocytosis with neutrophilia in 4 dogs, and normocytic, normochromic anemia in 6 dogs. Three dogs had suppurative lymphadenitis with many neutrophils. Cytology of the aspirate of pustules or abscesses in 6 dogs revealed many neutrophils without bacteria. Coagulase-positive Staphylococcus spp were isolated from draining lesions in 2 dogs. Intact abscesses and lymph nodes were negative for bacterial growth in 4 dogs. Three of these dogs were being administered antibiotics at the time of bacterial culturing. Cytology of the aspirates of joints in 3 of the 4 dogs with joint pain revealed suppurative arthritis with no bacteria, and the aspirates were negative for bacterial growth on culturing, although all 3 dogs were being administered antibiotics at the time of culturing. Of 12 dogs initially treated with antibiotics, only 4 (33%) responded favorably; the other 8 dogs were then given antibiotics and corticosteroids. Three dogs were initially given antibiotics and corticosteroids. All dogs treated concurrently with antibiotics and corticosteroids responded favorably. One of these dogs had a relapse after treatment was discontinued. The concurrent arthritis in 4 of the dogs resolved with treatment of the juvenile cellulitis and did not redevelop once the medication was discontinued. Concurrent treatment with antibiotics (cephalosporins) and prednisone (2.2 mg/kg of body weight/day) was the most consistently effective treatment in the dogs in this study.

Defective skin barrier characterize canine atopic dermatitis (AD). Pyoderma is the most common complication. Herbal compounds have been suggested as alternatives to control bacterial colonization for their effect on natural antimicrobial peptides (AMPs). This study evaluated the effects of 0.1% Peumus boldus leaf and Spiraea ulmaria plant extract combination on clinical signs, bacterial colonization and AMPs secretion in atopic dogs compared to placebo. Twenty privately-owned atopic dogs were randomly divided in 2 groups (treatment: n = 10; placebo: n = 10) and their abdomen was sprayed every 24 h for 4 weeks. Total and inguinal clinical scores (CADESI-03), manual bacterial count, and skin washes for AMPs (cBD3-like and cCath) were performed on days 0, 14 and 28. AMPs were detected using in-house, previously-validated, canine-specific ELISAs. Data were statistically analyzed and a p < 0.05 was considered significant. Clinical scores and AMPs secretion did not differ significantly between the two groups at any time point. A significant reduction of the clinical scores was seen in the placebo group at 14 and 28 days (p < 0.04). On days 14 and 28, a reduction in the bacterial count was seen in the treated group compared with placebo (p < 0.009 and p = 0.04, respectively). Compared to baseline, a reduction in Staphylococcus spp. was seen in the treated group after 14 days of treatment (p < 0.03). These results show the efficacy of this plant extract combination against bacterial colonization, suggesting its potential usefulness in preventing bacterial infection in atopic dogs. The influence of this compound on AMPs secretion or other mechanisms should be further evaluated. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

Systemic lupus erythematosus (SLE) is an autoimmune disease with multiorgan involvement. The skin is the second most commonly affected organ. SLE with skin lesions can produce considerable morbidity resulting from painful skin lesions, alopecia, disfigurement, etc. Skin lesions in patients with lupus may be specific (LE specific) or may be non specific (LE non specific). Acute cutaneous LE (Lupus specific) has a strong association with systemic disease and non-specific skin lesions always indicate disease activity for which patients present to rheumatologists and internists. Therefore, a thorough understanding of the cutaneous manifestations of SLE is essential for most efficient management. The aims of this study were to evaluate the patterns and prevalence of skin lesions in patients with SLE and to assess the relationship between skin lesions and other systemic involvement. At the Department of Rheumatology and Clinical Immunology, IPGME&R in Kolkata, 150 patients with SLE fulfilling the clinical and laboratory criteria of the American Rheumatology Association (updated 1982) were examined and followed-up for cutaneous manifestations between January 2002 and January 2007. Skin lesions were important clinical features. About 45 patients (30%) presented with skin lesions although all patients had skin lesions during the follow-up period. Skin changes noted were as follows: Lupus specific lesions: malar rash in 120 patients (80%), photosensitive dermatitis in 75 patients (50%), generalized maculopapular rash in 40 patients (26.67%), discoid rash in 30 patients (20%), subacute cutaneous lupus erythematosus (SCLE) in 5 patients (3.34%), lupus profundus in 5 patients (3.34%). The lupus non-specific lesions were non-scarring alopecia in 130 patients (86.67%), oral ulcers in 85 patients (56.67%), vasculitic lesions in 50 patients (33.34%), bullous lesions in 15 patients (10%), Raynaud's phenomenon in 10 patients (6.67%), pyoderma gangrenosum in 2 patients (1.34%), erythema multiforme in 10 patients (6.67%), and nail fold infarcts in 2 patients (1.34%); however, mucosal discoid lupus, lichenoid discoid lupus, livedo reticularis, sclerodactyly, etc. were not detected. Patients having lupus-specific skin lesions e.g., malar rash were associated with systemic involvement, whereas those having lupus non-specific skin lesions were associated with disease flare. Skin lesions in patients with SLE are important disease manifestations and proper understanding is essential for diagnosis and efficient management.

Blinding is the process of keeping treatment assignment hidden and is used to minimise the possibility of bias. Trials at high risk of bias have been shown to report larger treatment effects than low-risk studies. In dermatology, one popular method of blinding is to have independent outcome assessors who are unaware of treatment allocation assessing the endpoint using digital photographs. However, this can be complex, expensive and time-consuming. The objective of this study was to compare the effect of blinded and unblinded outcome assessment on the results of the STOP GAP trial. The STOP GAP trial compared prednisolone to ciclosporin in treating pyoderma gangrenosum. Participants' lesions were measured at baseline and at 6 weeks to calculate the primary outcome, speed of healing. Independent blinded assessors obtained measurements from digital photographs using specialist software. In addition, unblinded treating clinicians estimated lesion area by measuring length and width. The primary outcome was determined using blinded measurements where available, otherwise unblinded measurements were used (method referred to as trial measurements). In this study, agreement between the trial and unblinded measurements was determined using the intraclass correlation coefficient (ICC). The STOP GAP trial's primary analysis was repeated using unblinded measurements only. We introduced differential and nondifferential error in unblinded measurements and investigated the effect on the STOP GAP trial's primary analysis. Eighty-six (80%) of the 108 patients were assessed using digital images. Agreement between trial and unblinded measurements was excellent (ICC = 0.92 at baseline; 0.83 at 6 weeks). There was no evidence that the results of the trial primary analysis differed according to how the primary outcome was assessed (p value for homogeneity = 1.00). Blinded digital image assessment in the STOP GAP trial did not meaningfully alter trial conclusions compared with unblinded assessment. However, as the process brought added accuracy and credibility to the trial it was considered worthwhile. These findings question the usefulness of digital image assessment in a trial with an objective outcome and where bias is not expected to be excessive. Further research should investigate if there are alternative, less complex ways of incorporating blinding in clinical trials. Current Controlled Trials, www.isrctn.com ISRCTN35898459.

Responsible use of antimicrobials by veterinarians is essential to contain antimicrobial resistance in pathogens relevant to public health. Inappropriate antimicrobial use has been previously described in practice. However, there is scarce information on factors influencing antimicrobial usage in dogs and cats. We investigated intrinsic and extrinsic factors influencing decision-making of antimicrobial usage in first opinion small animal practices in the UK through the application of qualitative research methods. Semi-structured interviews were conducted with 21 veterinarians from seven veterinary first opinion practices in the UK in 2010. Topics investigated included: a) criteria used for selection of antimicrobials, b) influences by colleagues, c) influences by clients, d) pet characteristics, e) sources of knowledge, f) awareness of guidelines and g) protocols implemented in practice that may affect antimicrobial usage by veterinarians. Hypothetical scenarios selected to assess appropriateness of antimicrobial usage were: a) vomiting in a Yorkshire Terrier due to dietary indiscretion, b) deep pyoderma in a Shar-Pei, c) Feline Lower Urinary Tract disease in an 7 year-old male neutered cat and d) neutering of a 6-months dog. Interviews were recorded and transcribed by the interviewer. Thematic analysis was used to analyse content of transcribed interviews. Data management and analysis was conducted with qualitative analysis software NVivo8 (QSR International Pty Ltd). Antimicrobial usage by participants was influenced by factors other than clinical evidence and scientific knowledge. Intrinsic factors included veterinarian's preference of substances and previous experience. Extrinsic factors influencing antimicrobial selection were; perceived efficacy, ease of administration of formulations, perceived compliance, willingness and ability to treat by pet owners, and animal characteristics. Cost of therapy was only perceived as an influential factor in low, mixed socioeconomic areas. Veterinarians had limited awareness of current recommendations for responsible use in small animal practice. Social norms, particularly verbally agreed protocols influenced veterinarians. Inappropriate antimicrobial usage was identified in the therapy of non-infectious diseases and prophylaxis of routine clean surgical procedures. Discussion of clinical cases with peers and effectiveness meetings in the workplace were useful to veterinarians to share scientific knowledge. Effectiveness meetings can be a common ground for veterinarians to discuss and agree protocols for clinical conditions and surgical procedures. Protocols should be evidence-based, follow current recommendations and take into account the resources available in the workplace. Targeted training of veterinarians in the workplace with peer support should be used to promote responsible antimicrobial usage. Copyright © 2014 Elsevier B.V. All rights reserved.

Background Staphylococci are commensals of the mucosal surface and skin of humans and animals, but have been implicated in infections such as otitis externa, pyoderma, urinary tract infections and post-surgical complications. Laboratory records provide useful information to help investigate these infections. Therefore, the objective of this study was to investigate the burdens of these infections and use multinomial regression to examine the associations between various Staphylococcus infections and demographic and temporal factors among dogs admitted to an academic veterinary hospital in South Africa. Methods Records of 1,497 clinical canine samples submitted to the bacteriology laboratory at a veterinary academic hospital between 2007 and 2012 were included in this study. Proportions of staphylococcal positive samples were calculated, and a multinomial logistic regression model was used to identify predictors of staphylococcal infections. Results Twenty-seven percent of the samples tested positive for Staphylococcus spp. The species of Staphylococcus identified were S. pseudintermedius (19.0%), S. aureus (3.8%), S. epidermidis (0.7%) and S. felis (0.1%). The remaining 2.87% consisted of unspeciated Staphylococcus. Distribution of the species by age of dog showed that S. pseudintermedius was the most common (25.6%) in dogs aged 2–4 years while S. aureus was most frequent (6.3%) in dogs aged 5–6 years. S. pseudintermedius (34.1%) and S. aureus (35.1%) were the most frequently isolated species from skin samples. The results of the multivariable multinomial logistic regression model identified specimen, year and age of the dog as significant predictors of the risk of infection with Staphylococcus. There was a significant temporal increase (RRR = 1.17; 95% CI [1.06–1.29]) in the likelihood of a dog testing positive for S. pseudintermedius compared to testing negative. Dogs ≤ 8 years of age were significantly more likely to test positive for S. aureus than those >8 years of age. Similarly, dogs between 2–8 years of age were significantly more likely to test positive for S. pseudintermedius than those >8 years of age. In addition, dogs 2–4 years of age (RRR = 1.83; 1.09–3.06) were significantly more likely to test positive for S. pseudintermedius compared to those <2 years of age. The risk of infection with S. pseudintermedius or S. aureus was significantly higher in ear canal and skin specimens compared to other specimens. Conclusions The findings suggest that S. pseudintermedius and S. aureus were the most commonly isolated species from dogs presented at the study hospital. Age of the dog and the location of infection were significant predictors of infection with both Staphylococcus species investigated. Significant increasing temporal trend was observed for S. pseudintermedius but not S. aureus. This information is useful for guiding clinical decisions as well as future research. PMID:28417060

Sophora japonica (Fabaceae), also known as Huai (Chinese: ), is a medium-sized deciduous tree commonly found in China, Japan, Korea, Vietnam, and other countries. The use of this plant has been recorded in classical medicinal treatises of ancient China, and it is currently recorded in both the Chinese Pharmacopoeia and European Pharmacopoeia. The flower buds and fruits of S. japonica, also known as Flos Sophorae Immaturus and Fructus Sophorae in China, are most commonly used in Asia (especially in China) to treat hemorrhoids, hematochezia, hematuria, hematemesis, hemorrhinia, uterine or intestinal hemorrhage, arteriosclerosis, headache, hypertension, dysentery, dizziness, and pyoderma. To discuss feasible trends for further research on S. japonica, this review highlights the botany, ethnopharmacology, phytochemistry, biological activities, and toxicology of S. japonica based on studies published in the last six decades. Information on the S. japonica was collected from major scientific databases (SciFinder, PubMed, Elsevier, SpringerLink, Web of Science, Google Scholar, Medline Plus, China Knowledge Resource Integrated (CNKI), and "Da Yi Yi Xue Sou Suo (http://www.dayi100.com/login.jsp)" for publications between 1957 and 2015 on S. japonica. Information was also obtained from local classic herbal literature, government reports, conference papers, as well as PhD and MSc dissertations. Approximately 153 chemical compounds, including flavonoids, isoflavonoids, triterpenes, alkaloids, polysaccharides, amino acids, and other compounds, have been isolated from the leaves, branches, flowers, buds, pericarps, and/or fruits of S. japonica. Among these compounds, several flavonoids and isoflavonoids comprise the active constituents of S. japonica, which exhibit a wide range of biological activities in vitro and in vivo such as anti-inflammatory, antibacterial, antiviral, anti-osteoporotic, antioxidant, radical scavenging, antihyperglycemic, antiobesity, antitumor, and hemostatic effects. Furthermore, flavonoids and isoflavonoids can be used as quality control markers for quality identification and evaluation of medicinal materials and their preparations. Information on evaluating the safety of S. japonica is very limited, so further study is required. To enable safer, more effective, and controllable therapeutic preparations, more in-depth information is urgently needed on the quality control, toxicology data, and clinical value of crude extract and active compounds of S. japonica. S. japonica has long been used in traditional Chinese medicine (TCM) due to its wide range of biological activities, and is administered orally. Phytochemical and pharmacological studies of S. japonica have increased in the past few years, and the extract and active components of this plant can be used to develop new drugs based on their traditional application as well as their biological activities. Therefore, this review on the ethnopharmacology, phytochemistry, biological activities, and toxicity of S. japonica offers promising data for further studies as well as the commercial exploitation of this traditional medicine.

Tinea on a Tattoo.

2016-08-01

In the last twenty years, the prevalence of individuals with tattoos in the general population has increased in Europe (1) as well as in Australia (2) and the United States of America (3). A series of complications such as acute inflammatory reactions, allergic contact dermatitis (4,5), photoinduced, lichenoid, and granulomatous reactions (6, 7), pseudolymphoma (8), pseudoepitheliomatous hyperplasia (9), skin infections (6), and skin cancers (10) may occur on tattoos. Infectious complications on tattoos include bacterial infections (pyoderma, leprosy, syphilis, cutaneous tuberculosis, mycobacteriosis) (11-14), viral infections (molluscum contagiosum, warts, herpes simplex, hepatitis B and C) (15-17), and fungal infections (sporotrichosis, dermatophytosis) (18,19). We present the case of a 29-year-old immunocompetent female patient who was consulted for the development of an erythematous-squamous placard that appeared on a tattoo about 18 days after tattooing. Dermatological examination revealed a circular, erythematous, scaly plaque, with centrifugal growth and central resolution, presenting an active, raised, erythematous, vesiculopustular edge, giving the appearance of tinea corporis. The lesion's starting point was on the tattoo in two colors located on the middle third of the left calf and subsequently evolved to beyond the surface of tattoo (Figure 1). No other skin, scalp, or nail lesions were observed. Mycological examination of the material obtained by scraping of the scales and the vesicles from the edges and the surface of the plaque revealed numerous hyphae on direct microscopy examination, and white, flat colonies with a cottony surface and radial grooves developed in Sabouraud dextrose agar culture (Figure 2). Spindle-shaped, thick-walled macroconidia and a few pyriform microconidia were observed on microscopic examinations of the colonies. Based on macroscopic and microscopic characteristics, Microsporum canis was identified. Gram stain and bacterial culture results were negative. Patient history revealed the presence of a pet dog that was diagnosed with mycosis, the etiologic agent being M. canis. After 21 days of treatment with oral terbinafine (250 mg/day) and topical application of terbinafine 1% cream once a day, the lesion disappeared and mycological examination (direct microscopy and culture) was negative. In the case of tattoos, cutaneous inoculation of a dermatophyte may occur after 1-3 weeks of tattooing, corresponding to the healing phase of the tattoo application. Dermatophyte inoculation can be done by direct contact with an infected person or animal or, exceptionally, by telluric contamination. Despite the increasing number of tattooed people, there are only a few published cases of dermatophytosis arising on tattoos (19,20). Ammirati reported dermatophyte infection caused by Trichophyton tonsurans that occurred two weeks after tattooing, clinically presenting as concentric annular lesions with active vesiculopustular edges which progressively included the entire tattoo (19). Similarly, in our case the infection with M. canis occurred during the healing phase, the dermatophyte lesion occurring after 18 days from tattoo application by direct contact with the dog parasitized with M. canis. In conclusion, dermatophyte infection of tattoos remains possible, although rare.
