Pyoderma gangrenosum (PG) is a rare autoinflammatory neutrophilic dermatosis. The ulcerative subtype presents with a tender nodule or pustule that progresses into a painful, necrotic ulcer.New lesions arise after minor trauma in one-third of patients, a phenomenon termed "pathergy." We present a 62-year-old Caucasian female with primary sclerosing cholangitis, hepatic cirrhosis, chronic hepatitis B, and severe PG. At the initial presentation, she had lesions on her face and four extremities. She had severe full-thickness ulcerations on the bilateral cheeks and underwent incision and drainage with washout of bilateral maxillary abscesses, left sinus curettage, and wound debridement. She has required multiple hospitalizations for severe flares. Treatment with steroids was complicated by spinal compression fractures. Steroid-sparring agents were ineffective. Her lesions involved bilateral cheeks, temples, temporal scalp, and eyelids with oroantral fistulae. Her facial ulcerations included a large septal perforation causing saddle nose deformity and eradication of a branch of the left facial nerve causing incomplete eye closure. She underwent bilateral facial wound irrigation with antibiotic irrigation and wound debridement. Due to social factors, she has been lost to follow-up and a definitive etiology of her PG has not yet been elucidated. Although rare, PG should remain a consideration in patients with ulcerative lesions on the head and neck. Wound debridement is typically discouraged given the risk of pathergy, but there may be a role for surgical intervention in adequately immunosuppressed patients.

Review
Staphylococcus pseudintermedius is one species in the commensal staphylococcal population in dogs. While it is commonly carried on healthy companion dogs it is also an opportunistic pathogen associated with a range of skin, ear, wound and other infections. While adapted to dogs, it is not restricted to them, and we have reviewed its host range, including increasing reports of human colonisation and infections. Despite its association with pet dogs, S. pseudintermedius is found widely in animals, covering companion, livestock and free-living species of birds and mammals. Human infections, typically in immunocompromised individuals, are increasingly being recognised, in part due to improved diagnosis. Colonisation, infection, and antimicrobial resistance, including frequent multidrug resistance, among S. pseudintermedius isolates represent important One Health challenges.

Pyoderma gangrenosum (PG) is a neutrophilic dermatosis associated with underlying disorders. The association between PG and solid organ tumors (SM), including gynecologic cancers, has been previously reported. Here, we report a case of a 61-year-old woman with pyoderma gangrenosum on the posterior auricular region associated with an underlying fallopian tube carcinosarcoma: a rare and aggressive gynecologic malignancy. The patient's ulcer responded favorably to treatment, and surgical resection of the tumor was performed. The patient was then referred for further cancer management. No new lesions or recurrences were found over the 18 months of routine follow-up.

Pyoderma gangrenosum (PG) is an extremely rare case of sterile necrotic ulcerative disease associated with malnutrition as a predisposition factor. It is unclear, though, whether dilated cardiomyopathy, which affects blood flow and results in stenosis in the arteries, could play a role as an etiology. In this study, a case of pyoderma gangrenosum in a 10-year-old boy complicated by dilated cardiomyopathy, a previous history of cerebrovascular disease, and a malnourished condition were reported. The patient was reported to have exudative necrotic lesions in both legs. Lesions began as small, multiple, itchy lesions on both legs, which later became blisters and scuffed, and progressed into painful, peeled-off lesions with pus, bleeding, redness around lesions, and maggots within a month. A high fever was an accompanying symptom. The multidisciplinary team was involved to provide a comprehensive treatment for this patient. Antibiotics and necrotomy debridement were performed several times. Anticoagulant treatment was indicated as the coagulation markers were increased and echocardiography suggested thrombus in the left ventricle. The underlying condition that increases the risk of pyoderma gangrenosum should be corrected. The patient was discharged after a clinical improvement, although the continuation of outpatient monitoring was required. Our report suggests that a chronic condition of dilated cardiomyopathy that affects normal blood flow leads to malnutrition, the formation of thrombus, and stenosis of a peripheral artery, all of which contributed to pyoderma gangrenosum. Therefore, early surgical treatment, antibiotic administration, and anticoagulant treatment were recommended.

Review
THE PURPOSE OF THE ARTICLE
Pyoderma gangrenosum (PG) is an ulcerating neutrophilic dermatosis with an incidence of 3-10 patients per million. PG equally affects patients of both sexes and of any age. Of these patients, 50-75% are associated with auto-immune disease. The lower extremities are the most commonly affected body parts. Minor trauma to the skin may result in the development of new lesions. Patients complain of chronic, nonhealing ulcers with associated pain. Treatment starts with systemic or intralesional corticosteroids, however, no official treatment protocol currently exists. Recent success has been found with biologic agents such as TNF-a inhibitor, although the treatment efficacy in these reports is limited. As for the pregnant patient, the drug selection is difficult. In this report, we want to assess the efficiency of certolizumab in the pregnant patient.
RESULTS
We report a case of a patient with PG, who responded well to certolizumab, 400 mg as a booster dose, followed by 200 mg biweekly for 8 weeks. The lesions gradually resolved and followed up for 5months without side effect. In addition, we reviewed the literature and compared the current treatment efficiency in the treatment of PG.
CONCLUSION
Certolizumab may be a promising therapeutic option for patients with severe PG.

Pyoderma gangrenosum (PG) after breast-conserving surgery is rare, and its diagnosis is often delayed because of the similarity to wound infection and the broad differential diagnosis for PG, making it a diagnosis of exclusion. A 60-year-old woman who underwent breast conserving surgery and sentinel lymph node biopsy for invasive breast carcinoma presented with increasing erythema, fever and serosanguinous discharge in the lower outer quadrant of the right breast at the site of tumour excision on postoperative day (POD) 9. Fever persisted despite antibiotics and the patient was noted to have leucocytosis (0.9 x 10/L), neutrophilia (37.8 x 10/L) and elevated C-reactive protein levels (136 μg/mL) on POD 16. Microbiology and blood culture results were negative but the breast ulcer continued to expand at a rate of 1-2 cm a day. The patient underwent surgical debridement on POD 21 to rule out necrotising soft tissue infection. Persistent ulcer progression, despite debridement and antibiotics, led to clinical suspicion of PG and the patient was started on prednisolone and cyclosporin. A rapid response was seen with treatment and an optimum healing process was noted over the subsequent three-month follow-up period. Early suspicion, careful macroscopic evaluation of disease progression and appropriate use of immunosuppressive therapy are important for the management of PG. Prompt initiation of immunosuppressive therapy may avoid unnecessary treatment and aggravation of the surgical wound.

BACKGROUND
The Shar Pei is a common dog breed with a distinctive appearance caused by hyaluronosis that has been linked with several health conditions. Anonymised primary-care veterinary clinical records were explored to extract data on the demography, common disorders and mortality of Shar Pei in the UK in 2013.
RESULTS
The study population of 455,557 dogs included 1913 (0.42%) Shar Pei. The mean adult bodyweight was 22.26 kg. The most prevalent fine-level precision disorders were entropion (prevalence 17.88%, 95% CI: 16.16-19.59), otitis externa (16.36%, 95% CI: 14.70-18.02), ear disorders (6.69%, 95% CI: 5.57-7.81), aggression (5.23%, 95% CI: 4.23-6.22), and pyoderma (4.29%, 95% CI: 3.38-5.19). The most prevalent disorder groups were ophthalmologic (prevalence = 22.27%, 95% CI: 20.40-24.13), dermatological (21.01%, 95% CI: 19.19-22.84), aural (18.66%, 95% CI: 16.92-20.41), traumatic injury (7.53%, 95% CI: 6.35-8.71) and behavioural (7.21%, 95% CI: 6.05-8.37). The median longevity of 190 Shar Pei that died during the study period was 7.28 years (IQR 5.04-10.05, range 0.04-15.04). Of 184 deaths with a recorded method of death, 157 (85.33%) deaths involved euthanasia and 27 (14.67%) deaths were unassisted. Among 136 (71.58%) deaths with a recorded biomedical cause of death, the most common causes of death at group level precision were neoplasia (15.44%, 95% CI: 9.37-21.51), renal disorders (13.24%, 95% CI: 7.54-18.93), and behavioural disorders (11.03%, 95% CI: 5.76-16.29).
CONCLUSIONS
Almost one fifth of Shar Pei receive veterinary care each year for entropion, a condition linked strongly with the extreme conformation of thickened and folded skin and bristly hair that characterises the Shar Pei breed. Several other common disorders are also linked to hyaluronosis. Current UK legislation can help support efforts to avoid breeding or acquiring animals with extreme conformations and to promote adequate veterinary care for already-owned animals with extreme conformations.

INTRODUCTION
Pyoderma gangrenosum (PG) is a rare, difficult-to-treat neutrophilic ulcerative cutaneous condition that severely impacts those affected. Treatment options for PG are limited, and disease remission is not guaranteed. Hyperbaric oxygen treatment is a potential therapeutic option for treating various ulcerative conditions not frequently utilized for PG.
CASE REPORT
We present a case of a patient with treatment-resistant PG who achieved remission with adjunctive HBOT, and then later had difficulty achieving remission without HBOT during a future flare.
DISCUSSION
HBOT should be more readily considered as a treatment option for those with PG.

BACKGROUND
Takayasu arteritis (TA) is an uncommon chronic inflammatory and autoimmune disease primarily affecting large vessels, particularly the aorta and its branches. Skin manifestations have been documented in association with TA. Pyoderma gangrenosum (PG) is a chronic neutrophilic dermatosis characterized by destructive, necrotizing, and painful ulcers, predominantly found on the lower extremities. The coexistence of PG and TA is extremely rare, with most reported cases involving adult patients. Interestingly, the association between PG and TA appears to be more common in Japan compared to North American and European populations. Childhood TA (c-TA) accompanied by PG is exceptionally rare, with only 10 cases reported in the literature thus far.
CASE REPORT
We present the case of a 7-month-old patient initially diagnosed with PG. Despite aggressive immunosuppressive therapy, the patient`s high acute phase reactants remained elevated. Although the abdominal ultrasound was normal, advanced imaging was performed due to severe abdominal pain. Contrastenhanced computerized tomography angiography of the aorta and its branches revealed extensive vascular involvement consistent with TA.
CONCLUSION
In this report, we highlight an infantile case of PG that was subsequently diagnosed as infantile TA. Recognizing the rare association between PG and TA is important. Thorough evaluation and prompt diagnosis of TA in infants with PG can guide further investigations and prevent vascular complications.
