Necrotizing fasciitis in a patient with bullous pemphigoid treating with systemic steroid.

Necrotizing fasciitis (NF) is a rarely seen, life-threatening soft tissue infection characterized by progressive necrosis of skin, subcutaneous tissues and fasciae. Herein, we present a case of NF in a patient with bullous pemphigoid. A 78-year-old female patient was admitted with the left leg pain, swelling, redness and blistering. Streptococcus pyogenes was isolated from the wound culture. In the skin biopsy and the left leg magnetic resonance imaging, signs of NF were observed. The diagnosis of NF was considered. Then, urgent surgical debridement was performed by the department of plastic surgery. While under treatment with intravenous antibiotics therapy, unfortunately the patient died of acute renal insufficiency.

Environmental risk factors in pediatric psoriasis: a multicenter case-control study.

To analyze the effect of possible risk factors, including breastfeeding, on the development of childhood-onset psoriasis, a multicenter case-control study with prospective collection of data was performed. Using a standard questionnaire, personal and specific variables including family history of psoriasis, maternal and environmental tobacco smoke exposure, body mass index (BMI), exclusive and partial breastfeeding for at least 3 and 12 months, cow's milk intake before 1 year, birth delivery method, and stressful life events were collected during 2009 from 537 patients with psoriasis and 511 controls younger than 18. Overall, patients more frequently reported exposure to environmental tobacco smoke at home and stressful life events in the year preceding the diagnosis than controls. The odds ratios (OR) for smoking and stressful life events were 2.90 (95% confidence interval [CI]=2.27-3.78) and 2.94 (95% CI=2.28-3.79), respectively. In addition, children with psoriasis were more likely to have a higher BMI (>26) than controls (OR=2.52; 95% CI=1.42-4.49). High BMI, environmental tobacco smoke exposure at home, and stressful life events may influence the development of pediatric psoriasis.

Sulfasalazine-induced hypersensitivity syndrome in a 15-year-old boy associated with human herpesvirus-6 reactivation.

Drug-induced hypersensitivity syndrome (DIHS) is characterized by high fever, facial edema, diffuse maculopapular eruption, and multiorgan involvement. Human herpesvirus (HHV)-6 reactivation is an accepted criterion for the diagnosis of DIHS and has prognostic importance. We report a 15-year-old boy with juvenile rheumatoid arthritis who developed DIHS due to sulfasalazine, associated with reactivation of HHV-6.

DLQI scores in patients with keloids and hypertrophic scars: a prospective case control study.

BACKGROUND: Keloids and hypertrophic scars (HTS) can cause functional impairment and psychosocial burdens, both of which affects quality of life (QoL). Our aim was to compare Dermatology Life Quality Index (DLQI) scores in patients with keloids and HTS to those of psoriasis patients and normal controls. PATIENTS AND METHODS: Forty-eight consecutive patients with keloids and HTS and 48 with psoriasis vulgaris attending our dermatology outpatient clinic, as well as 48 sex- and age-matched healthy controls completed the DLQI. RESULTS: Total DLQI scores of patients with keloids and HTS (7.79 +/- 5.10) and psoriasis (8.73 +/- 5.63) were comparable and significantly higher than that of healthy controls (0.58 +/- 0.77). No significant difference were found between patients with psoriasis and patients with keloids and HTS in terms of the total DLQI scores and the subscale scores (p > 0.05) except "treatment" (p < 0.05) sub-scale scores which were higher in psoriasis. CONCLUSIONS: The QoL of patients with keloids and HTS is impaired as much as that of those with psoriasis. The DLQI questionnaire is a reliable and valid instrument for assessing the QoL in patients with keloids and HTS.

Clinical practice guidelines for the diagnosis and treatment of cutaneous leishmaniasis in Turkey.

BACKGROUND: Cutaneous leishmaniasis (CL) is a vector-born parasitic disease characterized by various skin lesions that cause disfiguration if healed spontaneously. Although CL has been endemic for many years in the southern regions of Turkey, an increasing incidence in nonendemic regions is being observed due to returning travelers and, more recently, due to Syrian refugees. Thus far, a limited number of national guidelines have been proposed, but no common Turkish consensus has emerged. OBJECTIVES: The aim of this study was to develop diagnostic and therapeutic guidelines for the management of CL in Turkey. METHODS: This guideline is a consensus text prepared by 18 experienced CL specialists who have been working for many years in areas where the disease is endemic. The Delphi method was used to determine expert group consensus. Initially, a comprehensive list of items about CL was identified, and consensus was built from feedback provided by expert participants from the preceding rounds. RESULTS: Evidence-based and expert-based recommendations through diagnostic and therapeutic algorithms according to local availability and conditions are outlined. CONCLUSION: Because CL can mimic many other skin diseases, early diagnosis and early treatment are very important to prevent complications and spread of the disease. The fastest and easiest diagnostic method is the leishmanial smear. The most common treatment is the use of local or systemic pentavalent antimony compounds.

Retrospective analysis of basal cell carcinoma.

BACKGROUND: Basal cell carcinomas (BCCs) are the most prevalent cancer type among white-skinned populations worldwide. AIMS: To analyze the gender and age-related incidence of basal cell carcinoma (BCC) histopathologic subtypes, to classify BCCs according to their anatomical location, invasion depth, and size, and to determine the relationship between BCC subtypes and margin of surgical excision. METHODS: All BCCs analysed in our center between 2005 and 2010 were studied retrospectively. The samples, which were totally excised, were included on the basis of histopathological diagnosis of BCC, and confirmed by two pathologists. Patient data included sex, age at diagnosis, tumor location, histological subtypes, invasion depth, and size. RESULTS: We recorded 197 BCCs obtained from 181 white patients (80 females, 101 males). The mean age among males was 64.11, and 59.33 among females. Of the cases, 45.17% were nodular, 22.33% were mixed, and 15.22 were infiltrative type. 91.84% of the cases were located on the head and neck, 3.04% were on the limbs, and 1.52 % were on the trunk. In 32 cases, the margin of surgical excision was positive (17.7%): nodular 12%, infiltrative 43.3%, mixed 20.6%, micronodular 10%, and superfacial multicentric 5.5%. Of these total 32 cases, 34.4% were located on the eyes region, 28.1% were found on the nose, and 15.6% were on the ears. Invasion depth of tumors varied from 0.5 to 22.125 mm. CONCLUSIONS: The results of our study exhibit differences in anatomical distribution, sex and mean age, invasion depth, and size of BCC subtypes. The recurrence rate for incompletely excised tumors varies according to the location and type of the tumor. Infiltrative tumors are more likely to recur and have positive margin of surgical excision. The highest positive margin of surgical excision is in infiltrative BCC. Tumors at difficult-to-treat sites and large and/or deeply invasive tumors are more liable to recur.
