Combined pulsed dye laser and Q-switched Nd:YAG laser intraumatic facial tattoo removal: A case series.

Traumatic tattoos can be treated with several methods, including mechanical and chemical devices. However, they are rarely used due to the high risk of permanent side effects such as scarring and depigmentation. Recently, laser devices, especially the Q-switched (QS) laser and the pulsed dye laser (PDL), applied in combination, have achieved complete clearance of the lesions without any risk of side effects. Herein, we reported three cases of traumatic facial tattoos successfully treated with combined PDL and QS Nd:YAG laser.

Randomized, within-patient, clinical trial comparing fluorine-synthetic fiber socks with standard cotton socks in improving plantar pustulosis.

BACKGROUND/AIMS: Rubbing the skin may influence the persistence of pustulosis over time. The aim of this study was to assess the impact of a new fabric made with fluorine-synthetic fiber in improving plantar pustulosis. METHODS: A total of 17 patients were randomized to receive on one side a sock made of fluorine-synthetic fiber and on the other a sock made of cotton fabric for 4 weeks. The main outcome was the percentage reduction of lesional area at week 4. RESULTS: The median lesion reduction at week 4 was 42.6% in the fluorine-synthetic fiber arm and 2.7% in the cotton arm (p = 0.148). Among secondary outcomes, the overall reduction over time in the treated areas was significantly in favor of the fluorine-synthetic fiber arm (p = 0.045) as well as the perception of the disease by the patient (p = 0.025). CONCLUSION: Despite the fact that the primary outcome was not reached, there was a tangible reduction in the extension of the treated areas and in the perception of the disease by the patient.

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.

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. A 40-year-old man was admitted in 2002 for progressive subcutaneous indurations, preferentially involving the right side of the trunk. His health was altogether good, with the exception of a beginning chronic obstructive bronchopneumopathy. There was no family or personal history of dysmetabolic, cardiovascular, neoplastic, or cutaneous disease. Three years earlier, the patient had noted the appearance of two infiltrated, intensely red lesions on the right laterocervical and paraumbilical regions. These had been interpreted as subcutaneous lipomatosis on the basis of an ultrasound scan. The lesions had become progressively larger, while their surface had assumed a scleroatrophic appearance. Thereafter, other lesions had developed on his chest and lower limbs, mostly distributed on the right side of the body. Clinical examination revealed well demarcated, depressed sclerotic plaques with ivory-colored centers and erythematous borders ("lilac ring") localized on the neck, chest, and lower abdomen and limbs (Figure 1). They were bound to the deeper structures and arranged in a band-like linear distribution on the right side of the chest and abdomen where they extended horizontally for more than 10 cm in diameter. These lesions were totally asymptomatic. In addition, arborizing telangiectasias were evident on the neck and upper chest (Figure 2). Laboratory investigations provided normal range of erythrocyte sedimentation rat and C reactive protein levels and other inflammation markers. Antinuclear antibody, antidouble-strand DNA, antimitochondrial, anti-extractable antigens (anti-centromere, anti-Scl-70, anti-U1RNP), and anti-Borrelia burgdorferi antibodies were negative. Circulating immunocomplexes binding C1q were substantially increased. Oesophageal x-rays and lower limb electromyography were within normal limits; ventilatory function testing revealed a mild obstruction consistent with the beginning of chronic obstructive pulmonary disease. Although nailfold capillaroscopy documented nonspecific findings of connective tissue disease (mega-capillaries, segmentary dilatation and destruction), the laser-Doppler flussimetry revealed few signs of microcirculatory abnormalities, in absence of Raynaud's phenomenon. An abdominal wall ultrasonography, performed on a sclerotic plaque, documented thinning of the subcutaneous tissue, with increase of the fibrous component and lower fascia and muscle retraction. The biopsy specimen from the abdominal region included fascia and the subcutaneous tissue (previously obtained from the lower abdomen) with epidermal atrophy, a thickening and homogenization of collagen bundles in the deep dermis and hair reduction. A perivascular lympho-monocytic and plasmacellular infiltration with a dermo-epidermal distribution was present. Moreover, septal fibrosis with a perivascular lymphoplasmacellular inflammatory infiltrate was documented within the abdominal rectus muscle. The diagnosis of morphea profunda was made on the basis of clinical and histopathological findings. A therapeutic regimen based on amino benzoic potassium (Potaba; Glenwood, LLC, Glenwood, NJ), oral prednisone, and topical clobetasol was started. After several months of follow-up, the patient had obtained only moderate improvement of the clinical findings.

Double-blind, within-patient, randomized, clinical trial comparing fluorine-synthetic fiber socks with standard cotton socks in improving plantar psoriasis.

BACKGROUND: Rubbing the skin and trauma may influence the persistence of psoriasis over time. OBJECTIVES: To assess the impact of a new fabric made with a special fluorine-synthetic fiber in improving plantar psoriasis. METHODS: A total of 20 patients with symmetrical lesions were randomized to receive on one side a sock made of fluorine-synthetic fiber and on the other side a sock made of cotton fabric for 4 weeks. The main outcome was the percentage reduction of lesional area. RESULTS: In an intention-to-treat analysis, the median lesion reduction was 11.95% in fluorine-synthetic fiber arm and 11.89% in cotton arm (p = 0.776). Among secondary outcomes, patient global satisfaction showed a statistically significant median score of 32 toward fluorine-synthetic fiber arm (p = 0.011). CONCLUSION: In spite of our main negative results, it is important to continue investigating on the relation between textiles and skin disorders to improve patient well-being.

Chronic idiopathic urticaria: infiltrating cells and related cytokines in autologous serum-induced wheals.

The term chronic autoimmune urticaria (CAIU) is used for chronic urticaria in subjects who present a whealing response to the intradermal injection of autologous serum, suggesting the presence of pathogenic antibody activities. In this study, we examined 28 chronic urticaria subjects with positive autologous serum skin test (ASST), all of whom presented autologous serum-induced lesions at different evolutive stages. Punch biopsies were taken from lesional skin of six subjects at 10', eight subjects at 30', six subjects at 60', and four subjects each at 24 and 48 h. Immunological studies focussed on infiltrating cell immunophenotype and related cytokines, chemokines and chemokine receptors, adhesion molecules. Immunohistochemical staining was performed to measure expression of CD3, CD4, CD8, tryptase, eosinophil cationic protein, myeloperoxidase, basophil granular protein, IL-4, IL-5, IL-8, CCR3 and CXCR3, ICAM-1, VCAM and ELAM. Control staining was done on unaffected skin from the patients and normal skin from four healthy donors. The main infiltrating population was represented by neutrophils, seen focally in both unaffected skin (P = 0.001) and healthy controls (P = 0.003). IFN-gamma and IL-5 were expressed focally in autologous wheals. Significant staining for IL-4 was seen at 30'. CCR3 and CXCR3 were expressed less in autologous wheals than in uninvolved skin (P < 0.0001; P = 0.002). Cellular adhesion molecules (CAMs) reached their highest expression at 30' and 60' in induced lesions, and they showed strong expression also in unaffected skin (ICAM-1: P < 0.0001). Our data show that the immunoinflammatory features of ASST-induced wheals involve a prevalent role of lymphocytes (with a mixed Th1/Th2 response), with strong neutrophil infiltration and activity and involvement of the chemokine pathway. We interpreted the finding of inflammatory cells and mediator up-regulation in uninvolved CIU skin as a sign of prolonged and widespread "urticarial status".
