Chronic Inducible Urticaria: Part II

Physical urticaria (PU) is a subgroup of acquired, chronic inducible urticaria which is associated with a known physical trigger. In PU, the symptoms are induced by exogenous physical triggers, such as friction, pressure, vibration, cold, heat, or solar radiation. All the PUs may manifest with both wheals and angioedema at the sites of the triggers with the exceptions that urticaria factitia (UF) (symptomatic dermatographism) presents with wheals only and pressure urticaria presents with angioedema only. More than one form of physically induced urticarias can be present in one patient

Dermatitis Herpetiformis

Dermatitis herpetiformis is an autoimmune skin disease, which is strongly related to coeliac disease. Moreover, some authors accept it as the skin manifestation of coeliac disease. It is a chronic, recurrent disease with polymorphic skin eruptions and pruritus. Dermatitis herpetiformis is a disease of the young adults mostly, but can be seen at any age. It is characterized by papules, vesicles, excoriations, and urticarial plaques clinically. Histopathological examination reveals subepidermal separation, and with this finding, it needs to be differentiated from linear IgA bullous dermatitis and bullous pemphigoid. In this case, direct immunofluorescence is helpful. Granular deposition of IgA is pathognomonic for dermatitis herpetiformis. Dermatitis herpetiformis can accompany other autoimmune disorders such as type I diabetes mellitus, thyroid diseases, vitiligo, and collagen tissue diseases. Dermatitis herpetiformis is, usually, successfully treated with dapsone and gluten-free diet

Effects of evening primrose oil and 5-fluorouracil on the healing of colonic anastomoses in rats

Aim: This study was designed to evaluate the efficacy of evening primrose oil (EPO) on colonic anastomosis. Methods: Sixty rats with colonic anastomosis were randomly divided into six groups. EPO and 5-Fluorouracil (5-FU) were administered at doses of 5 g/kg/day and 20 mg/kg/day, respectively.  Group 1 served as sham control. The rats in Group 2 (EPO) received EPO (14 days preoperatively), in Group 3 (Extended EPO) received EPO (14 days preoperatively and 7 days postoperatively), in Group 4 (5-FU) received intraperitoneally 5-FU (5 days preoperatively), in Group 5 (5-FU+EPO) received EPO (14 days preoperatively), and 5-FU (5 days preoperatively), in Group 6 (5-FU+ extended EPO) received EPO (14 days preoperatively and 7 days postoperatively)  and 5-FU (5 days preoperatively). Histopathological examination, bursting pressure, and hydroxyproline content were used for evaluation. Results: Significant differences were found between the Groups 1, 2, and 3 and Groups 4, 5, and 6 in bursting pressures. Polymorphonuclear leukocyte (PMNL) and lymphocyte infiltration was significantly less in group 3, compared to the control and group 2. The least PMNL infiltration was in group 6 compared to groups 4 and 5.  The hydroxyproline level was different in group 3 compared to the control and group 2. Furthermore, groups 5 and 6 were different compared to group 4. Conclusion: EPO had favorable effects on colonic anastomosis even in groups where 5-FU was used

Ozone Therapy and Hyperbaric Oxygen Treatment in Lung Injury in Septic Rats

Various therapeutic protocols were used for the management of sepsis including hyperbaric oxygen (HBO) therapy. It has been shown that ozone therapy (OT) reduced inflammation in several entities and exhibits some similarity with HBO in regard to mechanisms of action. We designed a study to evaluate the efficacy of OT in an experimental rat model of sepsis to compare with HBO. Male Wistar rats were divided into sham, sepsis+cefepime, sepsis+cefepime+HBO, and sepsis+cefepime+OT groups. Sepsis was induced by an intraperitoneal injection of Escherichia coli; HBO was administered twice daily; OT was set as intraperitoneal injections once a day. The treatments were continued for 5 days after the induction of sepsis. At the end of experiment, the lung tissues and blood samples were harvested for biochemical and histological analysis. Myeloperoxidase activities and oxidative stress parameters, and serum proinflammatory cytokine levels, IL-1β and TNF-α, were found to be ameliorated by the adjuvant use of HBO and OT in the lung tissue when compared with the antibiotherapy only group. Histologic evaluation of the lung tissue samples confirmed the biochemical outcome. Our data presented that both HBO and OT reduced inflammation and injury in the septic rats' lungs; a greater benefit was obtained for OT. The current study demonstrated that the administration of OT as well as HBO as adjuvant therapy may support antibiotherapy in protecting the lung against septic injury. HBO and OT reduced tissue oxidative stress, regulated the systemic inflammatory response, and abated cellular infiltration to the lung demonstrated by findings of MPO activity and histopathologic examination. These findings indicated that OT tended to be more effective than HBO, in particular regarding serum IL-1β, lung GSH-Px and histologic outcome

THE EFFECTS OF EPIDEMIOLOGICAL AND CLINICAL FINDINGS IN BEHCET'S DISEASE ON THE COURSE AND PROGNOSIS OF THE DISEASE

WOS: 000376693400029Aim: Behcet's Disease (BD) is s a complex disease which occurs as a result of the involvement of different systems. In this study, we aim to determine the importance of clinical findings and demographic data in its occurence and in understanding the prognostic importance of BD, and to establish the influencing factors of these findings. Materials and methods: We conducted a retrospective statistical analysis on the clinical and demographic data assessed by examining the patient charts of 703 patients with BD who were admitted to the Behcet outpatient clinic in Erciyes University Department of Dermatology between 1998-2010. Results: Seven hundred and three patients were included in this study, of which 297 (42.2%) were male, and 406 (57.8%) were female. The mean age at diagnosis of the disease was 30.1 +/- 19.1 years. Mucocutaneous findings were the most frequent and first seen findings of the disease. The most frequent finding after mucocutaneous ones was ocular involvement. It was observed that vascular involvement was more common in male patients compared to female ones. In contrast, genital ulcer, erythema nodosum and arthralgia were seen more in female patients than in males. Conclusion: There is not a specific laboratory, monitoring or histopathologic examining method for the diagnosis and assessment of the prognosis of the disease. Consequently, it seems that the age, gender, genotype and other existing clinical findings of the patient give a clue to the prognosis of the disease.Erciyes University, Scientific Research UnitErciyes UniversityThe current study was supported by Erciyes University, Scientific Research Unit.
