[Cutaneous lupus erythematosus and skin manifestations in systemic lupus erythematosus].

Skin manifestations are frequently observed in lupus erythematosus (LE) and are manifold. Nonspecific and specific symptoms can be differentiated with the latter belonging to the dermatologically well-characterized clinical entities of acute cutaneous, subacute cutaneous, chronic cutaneous as well as intermittent cutaneous LE. These forms are differentially related to systemic LE.

The role of cytokines in skin aging.

Cutaneous aging is one of the major noticeable menopausal complications that most women want to fight in their quest for an eternally youthful skin appearance. It may contribute to some maladies that occur in aging which, despite not being life-threatening, affect the well-being, psychological state and quality of life of aged women. Skin aging is mainly affected by three factors: chronological aging, decreased levels of estrogen after menopause, and environmental factors.

Ulcerative cutaneous lesions synchronously present with the diagnosis of primary lung cancer.

The percentage of patients with lung cancer that develop skin metastases is low. The diagnosis is usually made using clinical information and skin biopsy in patients with suspicious skin lesions and history of smoking or lung cancer. The prognosis for patients having lung cancer with skin metastasis is very poor.

Association of smoking with cutaneous manifestations in systemic lupus erythematosus.

Objective: To examine the association between smoking and cutaneous involvement in systemic lupus erythematosus (SLE).

Methods: We analyzed data from a multicenter Canadian SLE cohort. Mucocutaneous involvement was recorded at the most recent visit using the Systemic Lupus Erythematosus Disease Activity Index 2000 Update (rash, alopecia, and oral ulcers), Systemic Lupus International Collaborating Clinics/American College of Rheumatology (ACR) Damage Index (alopecia, extensive scarring, and skin ulceration), and the ACR revised criteria for SLE (malar rash, discoid rash, photosensitivity, and mucosal involvement).

Vascular endothelial growth factor (VEGF-a) in Fabry disease: association with cutaneous and systemic manifestations with vascular involvement.

Introduction: Fabry disease is an X-linked inherited metabolic disorder characterized by the deficiency of lysosomal α-galactosidase A enzyme. This leads to the accumulation, into lysosomes through the body, of glycosphingolipids, mainly Gb3. Skin involvement and progressive multi-organ failure are usually observed.

Be vigilant for scurvy in high-risk groups.

Scurvy is caused by prolonged dietary deficiency of vitamin C, the plasma concentration of which appears inversely related to mortality from all causes. Its clinical importance relates principally to its role as a cofactor in a number of enzyme reactions involved in collagen synthesis, dysfunction of which disrupts connective tissue integrity, resulting in impaired wound healing and capillary bleeding. In the UK, overt scurvy is diagnosed only rarely.

Telangiectasia macularis multiplex acquisita: a new entity in Chinese populations and an analysis of associated factors.

Background:   Telangiectasia macularis multiplex acquisita (TMMA) is a rarely documented entity with distinctive clinical manifestation. Most patients are middle-aged adults. It may be associated with other diseases such as hepatitis, diabetes, or cardiovascular diseases.

Response to hydroxychloroquine in Japanese patients with lupus-related skin disease using the cutaneous lupus erythematosus disease area and severity index (CLASI).

Background: Hydroxychloroquine (HCQ) is not available in Japan. To design a clinical trial of HCQ, we evaluated the response to HCQ in Japanese patients with lupus-related skin disease using the cutaneous lupus erythematosus disease area and severity index (CLASI).

Methods: Twenty-seven patients with lupus-related skin disease who started HCQ at four hospitals were included.

Environment and lupus-related diseases.

Clinical manifestations of lupus are encountered in a variety of disease entities, including isolated cutaneous lupus, undifferentiated connective tissue disease, mixed connective tissue disease, drug-induced lupus, overlap syndrome, and systemic lupus erythematosus (SLE). While each entity has been recognized as a specific disease with its own diverse clinical and serological pattern, one could argue that many findings are common. Could it be that all of these entities actually represent a spectrum of one disease? Could it be that rather than the genetic predisposition and hence controlled factors that govern this spectrum of diseases, that environmental factors associated with SLE could also play a role in the different entities of this spectrum? The traditional environmental triggers in SLE include sunlight and ultraviolet (UV) light, infections, smoking, and medications including biologics such as tumor necrosis factor alpha (TNF-a) blockers.

Hidradenitis suppurativa: a review of cause and treatment.

Purpose Of Review: Hidradenitis suppurativa is a chronic or relapsing inflammatory cutaneous disorder manifested by recurrent formation of abscesses, fistulating sinus and scarring in the apocrine-gland-bearing skin. This review discusses the different aetiological theories and management opportunities.

Recent Findings: Current understanding of the pathogenesis suggests that hyperkeratosis of the infundibulum, leading to follicular occlusion of the pilosebaceous unit plays a role.

Livedo racemosa, secondary to drug-induced systemic lupus erythematosus.

We present a 40-year-old man with erythematous-to-violaceous, broken, reticulated patches on the upper chest, back, and extremities, which is consistent with livedo racemosa. The cutaneous findings appeared after an increase in dilantin dose and subsequently improved after a reduction in dilantin dose. Furthermore, antinuclear antibodies and antihistone antibodies were detected.

Cutaneous lupus erythematosus: update of therapeutic options part I.

In patients with cutaneous lupus erythematosus (CLE), it is important to provide instructions concerning methods of protection from sunlight and artificial sources of ultraviolet radiation. Topical corticosteroids are the mainstay of treatment for patients with CLE; however, they are of limited value because of their well-known side effects. Recently, calcineurin inhibitors have been shown to be efficient as topical therapy in various CLE subtypes.

Panniculitis: another clinical expression of gout.

Gouty panniculitis is an unusual clinical manifestation of gout, characterized by the deposition of monosodium urate crystals in the lobular hypodermis. Its pathogenesis is poorly understood but is associated with hyperuricemia, and the clinical presence of indurate subcutaneous plaques, which may precede or appear subsequently to the articular clinical expression of tophaceous gout. The aim of this report is to describe the clinical characteristics and potential risk factors for the development of lobular panniculitis secondary to chronic tophaceous gout.

Intrathoracic manifestations of Rosai-Dorfman disease.

Introduction: Rosai-Dorfman Disease (RDD), also known as Sinus Histiocytosis with Massive Lymphadenopathy (SHML), is a rare monocyte/macrophage proliferative disorder of varied biological behavior. Although cutaneous and lymph node involvement are relatively well-described, intrathoracic manifestations of RDD have only occasionally been reported.

Methods: We conducted a retrospective computer-assisted search of the Mayo Clinic record from 1976 to 2005 for patients with histopathologic evidence of RDD on organ biopsy.

Rheumatic manifestations of skin disease.

Purpose Of Review: There is an increasing interest in improving the understanding of pathophysiology, outcome measures, and therapies of rheumatic skin disease. Increasingly, studies are using the skin as a primary endpoint for evaluating therapies. This will review the current state of the art for the most common rheumatic skin diseases.

Allodynia in migraine: association with comorbid pain conditions.

Background: Cutaneous allodynia (CA) in migraine is a clinical manifestation of central nervous system sensitization. Several chronic pain syndromes and mood disorders are comorbid with migraine. In this study we examine the relationship of migraine-associated CA with these comorbid conditions.

Association of cigarette smoking but not alcohol consumption with cutaneous lupus erythematosus.

Objective: To ascertain whether smoking or alcohol consumption is associated with lupus erythematosus (LE), because this topic is still subject to debate and part of the debate could be related to the fact that smoking and alcohol consumption are specific risk factors for cutaneous LE.

Design: Prospective multicenter case-control study.

Setting: Three French university hospitals.

Influence of inherited and acquired thrombophilic defects on the clinical manifestations of mixed cryoglobulinaemia.

Objective: To investigate the contribution of inherited and acquired thrombophilic defects to the clinical manifestations of mixed cryoglobulinaemia vasculitis.

Methods: The following thrombophilic defects were investigated in 64 consecutive patients with HCV-associated mixed cryoglobulinaemia: aPLs, lupus anti-coagulant, homocysteinaemia, protein C and protein S concentrations, activated protein C resistance, plasminogen activator inhibitor-1 4G4G and 5G5G genotypes, and the presence of mutations of factor V (Leiden and H1299R), of prothrombin (G20210A) and of methyl tetrahydrofolate reductase (C677T and A1298C). Additional variables were demographic data, duration of the disease, cryocrit level and vascular risk factors (diabetes, hypertension, hypercholesterolaemia and smoking habit).

Clinical and laboratory characteristics of Finnish lupus erythematosus patients with cutaneous manifestations.

Our objective was to characterize clinical features, laboratory findings, concomitant autoimmune diseases, and smoking habits of lupus erythematosus subgroups in genetically homogeneous patients from two Dermatology Departments of Finnish University hospitals. One hundred and seventy eight discoid lupus erythematosus, 55 subacute cutaneous lupus erythematosus, and 77 systemic lupus erythematosus patients were enrolled using patients' charts from institutional database (1995-2006) and during routine control visits. Clustering analysis was performed to reveal natural groupings.

Insulin resistance and lichen planus in patients with HCV-infectious liver diseases.

Background And Aim: Hepatitis C virus (HCV) causes liver diseases and extrahepatic manifestations, and also contributes to insulin resistance and type 2 diabetes mellitus (DM). The aims of the present study were to examine the incidence of extrahepatic manifestations including lichen planus in HCV-infected patients and to evaluate the relationship between lichen planus and insulin resistance.

Methods: Of 9396 patients with liver diseases presenting to the study hospital, 87 patients (mean age 60.

Palmar erythema.

Palmar erythema (PE), an often overlooked physical finding, is due to several physiologic or systemic pathologic states. PE can exist as a primary physiologic finding or as a secondary marker of systemic pathology. Primary or physiologic PE can be due to heredity, occurs in at least 30% of pregnant women as a result of associated alterations in the function of the skin and its microvasculature, or may be a diagnosis of exclusion (i.

Tobacco habits modulate autosomal dominant nocturnal frontal lobe epilepsy.

Mutations in neuronal nicotinic acetylcholine receptors have been demonstrated in autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE). The beneficial effect of nicotine administration was previously reported in one single case. We investigated the influence of the tobacco habits of 22 subjects from two pedigrees with alpha4 mutations (776ins3 and S248F).

Subacute cutaneous lupus erythematosus: 25-year evolution of a prototypic subset (subphenotype) of lupus erythematosus defined by characteristic cutaneous, pathological, immunological, and genetic findings.

Subacute cutaneous lupus erythematosus (SCLE) represents a widespread, photosensitive, nonscarring, nonindurated form of lupus erythematosus (LE)-specific skin disease. SCLE lesions are associated with a distinctive immunogenetic background including the production of Ro/SS-A autoantibodies. Individuals who have SCLE skin lesions as a component of their presenting illnesses represent a distinctive subset (subphenotype) of LE that enjoys a good prognosis with respect to life-threatening systemic manifestations of LE.
