ABSTRACT
Introduction@#Pyoderma gangrenosum (PG) is a rare inflammatory disease with unknown etiology. Ulcerative PG presents with a rapidly enlarging painful ulcer with erythematous and undermined border often misdiagnosed as infection, vascular disorder, malignancy, and other inflammatory disease. Hence, this poses a diagnostic challenge for clinicians leading to a delay in the management and significant morbidity. The treatment of PG is equally challenging due to the rarity of the disease and the scarcity of clinical trials. Currently, there are no clinical practice guidelines for the management of PG. @*Case Report@#Our patient presented with multiple large ulcers with erythematous and undermined borders over the chest, abdomen, and the lower back. Cribriform scars and contractures were noted as well. She underwent several sessions of surgical debridement and was given different broad-spectrum antibiotics with noted worsening of the lesions. Due to extensive involvement of the disease, her quality of life has been significantly affected. A diagnosis of PG was made after the biopsy showed predominantly neutrophilic infiltrate. Prednisone 1mg/kg/day and clobetasol propionate ointment were initiated with significant decrease in pain and size of the ulcers after one month of therapy. Doxycycline was used as an adjunct therapy with excellent response.@*Conclusion@#Pyoderma gangrenosum is a rare, debilitating disease that remains a diagnostic dilemma. The worsening of ulcers despite surgical debridement and antibiotics is a clue that should prompt clinicians to consider PG. This case highlights the important role of dermatology in individuals who present with non-healing chronic ulcers because as seen in this case, not all ulcers are just ulcers.

Pyoderma Gangrenosum , UlcerABSTRACT
@#INTRODUCTION: Exfoliative dermatitis is a potentially life- threatening inflammatory reaction that poses a significant risk for morbidity and mortality. Several underlying etiologies of this dermatologic condition include pre-existing dermatoses, drugs and malignancy. Although it is a common disease entity, local studies on exfoliative dermatitis published in literature are very limited. OBJECTIVE: The primary objective of this study is to determine the epidemiological profile of patients with exfoliative dermatitis diagnosed at University of Santo Tomas Hospital Dermatology department from January 2008 to December 2012. METHODS: Inpatient and outpatient clinical records of patients diagnosed and treated as exfoliative dermatitis were retrieved. The prevalence, clinical presentation, history of previous dermatoses or use of any drugs/topical medications, family history and accompanying systemic symptoms were reviewed and analyzed. RESULTS: A total of 67 patients were included in this retrospective study. The prevalence among patients with exfoliative dermatitis in this study was computed at 1 per 1000 dermatologic patients. The highest number of cases belonged to the group aged seventy-one to seventy-nine (25.4%) with a mean age of 56.62 years. There was a male predilection (65.7%). Clinical presentation of patients included pruritus, generalized scaling and erythema, accompanied by bipedal edema (41.8%), chills (22.4%), fever (T ≥ 38 °C), lymphadenopathies (6%) and joint pains (4.5%). Several etiologic factors of exfoliative dermatitis recorded were: pre-existing dermatosis (67.2%), idiopathic or undetermined causes (19.4%), drug-induced (10.4%) and malignancy (3%). CONCLUSION: Exfoliative dermatitis is a condition more commonly found in the older age group. Pre-existing dermatoses, drugs and malignancy are etiologic factors. The most common pre-existing dermatosis causing exfoliative dermatitis in this study is psoriasis while the most implicated drug is allopurinol.

Dermatitis, ExfoliativeABSTRACT
@#INTRODUCTION: Acne vulgaris has multifactorial causes. Prolonged systemic antibiotics are often necessary because relapse of lesions occurs upon its discontinuation. Currently, antimicrobial resistance is a growing concern. Androgen inhibitors like metformin may decrease need for antibiotics and maintain adequate control of the disease. OBJECTIVE: To determine the efficacy and safety of metformin versus placebo as an adjunct to lymecycline and adapalene+benzoyl peroxide gel in the treatment of moderate to severe acne vulgaris METHODS: Patients with moderate to severe acne vulgaris received either metformin or placebo tablets, together with lymecycline and adapalene+benzoyl peroxide gel. Lymecycline was taken for six weeks. The rest were given for 18 weeks. Evaluation was done biweekly using the mean reduction rates of non-inflammatory, inflammatory and total lesion count, modified global severity score, subjective self-assessment score, Dermatology life quality index (DLQI) score, and cutaneous and systemic adverse events. RESULTS: Forty patients were selected for the trial. Mean reduction rates of the non-inflammatory lesion counts of the two groups were comparable (p>0.05). Mean reduction rates of the inflammatory and total lesion count in the metformin group were higher than the placebo group (p<0.05). The mean modified global severity score of the metformin group was lower than the placebo group (p=0.034). Mean DLQI scores decreased in both groups (p<0.0001). Subjective self-assessment scores improved in both groups with comparable results. Cutaneous adverse events (erythema, pain, scaling, and dryness) were tolerable. Systemic adverse events (diarrhea, flatulence, headache, and epigastric pain) were self-limited CONCLUSION: Metformin is an effective and safe adjunct in the treatment of moderate to severe acne vulgaris.
