Efficacy and safety of N-acetyl-GED-0507-34-LEVO gel in patients with moderate-to severe facial acne vulgaris: a phase IIb randomized double-blind, vehicle-controlled trial.

Background: Preliminary in vitro and in vivo studies have supported the efficacy of the peroxisome proliferator-activated receptor-γ (PPARγ) modulator N-acetyl-GED-0507-34-LEVO (NAC-GED) for the treatment of acne-inducing sebocyte differentiation, improving sebum composition and controlling the inflammatory process.

Objectives: To evaluate the efficacy and safety of NAC-GED (5% and 2%) in patients with moderate-to-severe facial acne vulgaris.

Methods: This double-blind phase II randomized controlled clinical trial was conducted at 36 sites in Germany, Italy and Poland.

Female Patients with Dermatitis Herpetiformis Show a Reduced Diagnostic Delay and Have Higher Sensitivity Rates at Autoantibody Testing for Celiac Disease.

Objective: Our objective was to characterize the demographic information, clinical features, and laboratory data of patients with dermatitis herpetiformis (DH).

Methods: In this multicentre cross-sectional study, consecutive patients with a new diagnosis of DH that referred to nine different Italian centers between 2011 and 2016 were characterized assessing demographic, clinical and laboratory findings, and evaluating gender and age differences across selected variables.

Results: A total of 151 patients were included.

Adult female acne and associated risk factors: Results of a multicenter case-control study in Italy.

Background: The reasons for the appearance of acne in adulthood are largely unknown.

Objective: We explored the role of personal and environmental factors in adult female acne.

Methods: We conducted a multicenter case-control study in the outpatient departments of 12 Italian cities.

Tuscan consensus on the diagnosis, treatment and follow-up of moderate-to-severe psoriasis.

Background: Psoriasis is traditionally defined as an inflammatory chronic-relapsing disease of the skin. As widely demonstrated, this disease is also associated with multiple comorbidities: arthropathy, inflammatory bowel disease, metabolic, cardiovascular, ocular and psychological disorders. The disease also has a significant impact on patients' quality of life, whose work ability decreases considerably with clear consequences for the social costs.

Tripe palms associated with malignant acanthosis nigricans in a patient with gastric adenocarcinoma: a case report and review of the literature.

Tripe palms (TP) is a rare dermatologic condition. TP alone, or associated with malignant acanthosis nigricans (MAN), in most cases is a cutaneous paraneoplastic disorder and its recognition should prompt a full diagnostic work-up for an underlying malignancy. We report a case of a patient in whom the correct identification of TP and MAN has allowed early diagnosis of gastric cancer.

Generalized B-cell non Hodgkin's lymphoma in association with leukocytoclastic vasculitis and disseminated intravascular coagulation.

A 66-year-old woman was referred a 4-month history of asthenia, weight loss, productive cough, increasing dyspnea, epigastric pain, and night sweats. A B-cell non-Hodgkin lymphoma was discovered in association with a severe leukocytoclastic vasculitis and disseminated intravascular coagulation. The patient was treated successfully with the combination of cyclophosphamide, vincristine, prednisone, and rituximab.

A case of nodular scleroderma.

Nodular scleroderma is a rare complication of systemic sclerosis; the pathogenetic implications are still unknown, although many factors are supposed to play a role in lesion development. We report the case of a young woman suffering from systemic sclerosis, who developed nodular lesions during therapeutic management with D-penicillamine and plasmapheresis. In order to better understand the essence of this disease, we examined all the possible pathogenetic mechanisms that could be implicated in nodular lesion development.

A case of lichenoid drug eruption associated with sildenafil citratus.

A 53-year-old man developed lichenoid lesions on the upper chest, posterior surfaces of the trunk, and abdominal region about three months before his first visit. Physical examination and laboratory findings were normal; histopathology showed vacuolar degeneration of basal keratinocytes in association with a dense lympho-histioid infiltrate arranged in a lichenoid pattern with a few melanophages and eosinophils. The fact that our patient had been irregularly taking sildenafil citratus (Viagra) led to the hypothesis of a lichenoid drug-induced eruption.

Case study: periodic follow-up is necessary in morphea profunda to identify systemic evolution.

The term "morphea" includes a wide spectrum of clinical entities, varying from localized plaques of only cosmetic importance to deep lesions resulting in considerable morbidity for the patient. In fact, although survival rates are no different from that of the general population, localized scleroderma may be associated with development of substantial disability, as occurs in deep morphea and in pediatric patients (disabling pansclerotic morphea of children). We report a case of morphea profunda affecting a young man with severe, rapidly progressive, widespread skin involvement and focus on the eventual systemic evolution of such cases.

Systemic lupus erythematosus with unusual maculopapular and erosive cutaneous lesions.

In 2002, a 38-year-old woman was referred to the department of dermatological sciences for the evaluation of erythematous-infiltrated lesions with prominent purpuric and erosive components distributed on her face, upper chest, and extensor surfaces of the limbs, which developed over a 3-month period. In 1997 the patient suffered from polyarthralgia (proximal interphalangeal,knee, wrist, and metacarpophalangeal joints) associated with morning stiffness. In 1999 she was admitted to a psychiatric unit for depression with episodes of lipothymia.

Chronic idiopathic and chronic autoimmune urticaria: clinical and immunopathological features of 68 subjects.

Skin tests with autologous serum elicit an immediate wheal-and-flare response in about 30-50% of chronic idiopathic urticaria subjects, suggesting that an autoimmune mechanism might be involved in the pathogenesis of this disease. The aim of the present work, involving 68 subjects with chronic idiopathic urticaria, was to distinguish between the serum-positive and serum-negative cases and highlight the clinical differences between the two groups on the basis of the Breneman scale score. We also tried to correlate the finding of a positive response to the autologous serum skin test with other autoimmune diatheses or fully developed autoimmune disorders.

Case study: pachyonychia congenita: a mixed type II-type IV presentation.

A 52-year-old woman in good health with a family history negative for dermatologic diseases presented to our department with thickening and dystrophy of all her fingernails and toenails that started when she was born. She also had hyperkeratosis on the palms of her hands and soles of her feet that was confined to sites of pressure and recurrent plantar blisters that began appearing at puberty. The patient reported marked pain while walking from such plantar involvement.

Systemic contact dermatitis from herbal and homeopathic preparations used for herpes virus treatment.

Systemic contact dermatitis may occur in contact-sensitized individuals when they are exposed to haptens orally, transcutaneously, intravenously or by inhalation. We report the case of a woman developing a diffuse skin eruption after the topical use of Rhus toxicodendron alcoholic extract and the oral introduction of a homeopathic preparation of the same substance for herpes treatment. An open test, performed with the Rhus toxicodendron tincture, showed an erythemato-oedematous response at 48 h and vesicular reaction at 96 h that was still present after 7 days.

Cutaneous lupus erythematosus: diagnosis and management.

Cutaneous lupus erythematosus (CLE) includes a variety of lupus erythematosus (LE)-specific skin lesions that are subdivided into three categories - chronic CLE (CCLE), subacute CLE (SCLE) and acute CLE (ACLE) - based on clinical morphology, average duration of skin lesions and routine histopathologic examination. This paper describes our personal experience in the management of CLE over the last 30 years, with details on preferential therapeutic options related to clinical, histologic and immunopathologic aspects of each clinical subset of the disease. Effective sunscreening and sun protection are considered the first rule in the management of CLE because of the high degree of photosensitivity of the disease.

Serum eosinophil cationic protein, myeloperoxidase, tryptase, eotaxin and Th2-L-like cytokines in Dermatitis herpetiformis.

Background: Dermatitis herpetiformis (DH) is a subepidermal bullous disease characterized by a neutrophilic and eosinophilic infiltrate, together with activated lymphocytes that show preferential polarization towards the Th2-like phenotype. To date, the role of neither soluble mediators, such as cytokines, nor serum levels of myeloperoxidase (MPO), eosinophil cationic protein (ECP) and tryptase (TRY) have been studied in the peripheral blood of DH. In this study we investigated 40 DH subjects for possible alterations in MPO, ECP, TRY, eotaxin, interleukin (IL) 4 and IL-5 concentrations to evaluate the role of neutrophils, eosinophils and mast cells in the induction of skin lesions.
