Can chronic spontaneous urticarial produce symptoms of neuropathic pain?

Abstract Background Chronic spontaneous urticaria (CSU) is a condition that is associated with recurrent pruritic hives and/or angioedema lasting for more than 6 weeks and is known to affect 1% of the population. Neuropathic pain can be defined as abnormal pain in the peripheral or central nervous system following injury and results from dysfunctions in the peripheral or central nervous system without peripheral nociceptor stimulation. Histamine appears in the pathogenesis of both the CSU and diseases of the neuropathic pain spectrum. Objective To evaluate the symptoms of neuropathic pain in patients with CSU using scales. Method Fifty-one patients with CSU and 47 sex- and age-matched healthy controls were included in the study. Results The results of the short-form McGill Pain Questionnaire revealed the scores in the sensory and affective domains, Visual Analogue Scale (VAS) scores and pain indices to be significantly higher in the patient group (p < 0.05 for all cases), while the overall pain assessment and sensory assessment based on the Self-Administered Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) pain scale were also significantly higher in the patient group. Based on the assumption that scores of > 12 indicated neuropathy, 27 (53%) of the patients in the patient group and 8 (17%) in the control group were found to have neuropathy (p < 0.05). Study limitations Cross-sectional study, small patient sample and use of self-reported scales. Conclusion In addition to itching, patients with CSU should be aware of the potential for the association of neuropathic pain. In this chronic disease that is known to affect the quality of life, using an integrated approach with the patients and identifying accompanying problems are as important as treating the dermatological disorder.

A very rare localization of a rare disease: palmar lichen nitidus

Abstract Lichen nitidus is an uncommon lichenoid dermatosis that could be defined as multiple, separated, shiny, pinpoint, pale to skin-colored papules. Palmoplantar lichen nitidus is a quite rare variant of lichen nitidus. It is hard to make a diagnosis of palmar lichen nitidus when there are no lesions elsewhere on the body. There are some dermoscopic features defined for both palmoplantar and non-palmoplantar lichen nitidus that might be useful to facilitate the diagnosis before histopathological examination. Herein, we report a case of a 24-year-old man diagnosed with isolated palmar lichen nitidus with dermoscopic features and histopathological confirmation.

Noninvasive assessment of subclinical atherosclerosis in patients with rosacea.

BACKGROUND: Rosacea is a chronic, inflammatory cutaneous disorder that is characterized by remissions and relapses that commonly occur in patients over the age of 30 years. There have been many studies in literature evaluating the relationship between cardiovascular disease and psoriasis, which is a chronic inflammatory disease; however, there have been very few studies to date evaluating the relationship between rosacea and cardiovascular disease risk. METHODS: The study included 52 consecutive rosacea patients and 52 healthy controls matched for age, gender and Body Mass Index. Demographic data, anthropometric measurements, lipid parameters, C-reactive protein (CRP), epicardial fat thickness (EFT) and carotid intima-media thickness (CIMT) were recorded. RESULTS: The main finding of the present study is the significantly higher EFT (P˂0.001) and CIMT (P˂0.001) values identified in patients with rosacea than in the control group and CRP (P=0.004), total cholesterol (P=0.003) and low-density lipoprotein (P=0.004) levels were also significantly higher in the rosacea group. EFT was significantly correlated with CIMT in the rosacea group (P=0.041). Total cholesterol (OR=1.032, P=0.017), CIMT (OR=7.391, P˂0.001) and EFT (OR=3.959, P=0.036) were independently associated with rosacea. CONCLUSIONS: Clinicians should be aware of the risk of cardiovascular disease when presenting with conditions involving persistent subclinical inflammation, as in the case of rosacea. EFT and CIMT measurements, which are noninvasive, easily accessible and cheap, can be useful to determine cardiovascular risk in rosacea patients.

A case of pediatric psoriasis achieving remission after allogenic bone marrow transplantation.

BACKGROUND: Psoriasis is an inflammatory skin disease in which the cells and molecules of innate and adaptive immunity are involved in the pathogenesis. Aplastic anemia is a bone marrow deficiency syndrome that is characterized by an extreme reduction in the number of blood cells as a result of failure in hematopoiesis. Allogenic hematopoietic stem cell transplantation is a promising treatment for Aplastic Anemia and it is important to note that other comorbid diseases like psoriasis- since both have some common pathogenetic mechanisims- might achieve remission after treatment. CASE: We present a 12-years-old male patient who underwent bone marrow transplantation for aplastic anemia and his psoriasis vulgaris lesions completely regressed. The final follow-up visit on day 150 also revealed no sign of the pre-transplantation skin and scalp lesions. CONCLUSIONS: This is the first case of pediatric psoriasis together with aplastic anemia that achieved complete remission of psoriasis after bone marrow transplantation. Our case report needs to be supported by prospective studies involving larger patient populations.
