Fluorescence advanced videodermoscopy: a new method of hairs and scalp evaluation. Comparison with trichoscopy.

INTRODUCTION: Non-invasive diagnostic methods in clinical dermatology are widely used to reduce the need for invasive techniques, with great advantages in terms of cost and time. Dermoscopy is the reference test for the in vivo diagnosis of cutaneous lesions, and when it is performed on the scalp region it is named trichoscopy. Fluorescence advanced videodermoscopy (FAV) has been lately proposed as a new non-invasive method for the in vivo skin examination at high magnification, with cell-level resolution. So far, it has shown promising results for the assessment of melanocytic and vascular lesions and for the in vivo diagnosis of parasitosis. OBJECTIVES: This observational study aims to perform, for the first time, a morphologic study of healthy scalp and scalp elementary lesions using FAV and to compare it with trichoscopy. METHODS: We enrolled 90 healthy individuals for the evaluation of the scalp using FAV. Then, we recruited 53 patients with alopecia and collected images of the elementary lesions using FAV and trichoscopy. RESULTS: Three hundred healthy scalp FAV images of different epidermal layers, papillary dermis, follicular ostia and healthy hair shafts were collected. Three hundred and eighty FAV and trichoscopic images of alopecic scalp elementary lesions were collected, showing that FAV provided a more detailed observation than trichoscopy, with higher magnification and cellular resolution. CONCLUSION: Fluorescence advanced videodermoscopy may represent a new valid technique of support to trichoscopy, adding further information, increasing chances of diagnosis and decreasing the need of invasive procedures.

A preliminary study on topical cetirizine in the therapeutic management of androgenetic alopecia.

BACKGROUND: Androgenetic alopecia (AGA) is a common form of scalp hair loss that affects up to 50% of males between 18 and 40 years old. Several molecules are commonly used for the treatment of AGA, acting on different steps of its pathogenesis (Minoxidil, Finasteride, Serenoa repens) and show some side effects. In literature, on the basis of hypertrichosis observed in patients treated with analogues of prostaglandin PGF2a, it was supposed that prostaglandins would have an important role in the hair growth: PGE and PGF2a play a positive role, while PGD2 a negative one. OBJECTIVE: We carried out a pilot study to evaluate the efficacy of topical cetirizine versus placebo in patients with AGA. PATIENTS AND METHODS: A sample of 85 patients was recruited, of which 67 were used to assess the effectiveness of the treatment with topical cetirizine, while 18 were control patients. RESULTS: We found that the main effect of cetirizine was an increase in total hair density, terminal hair density and diameter variation from T0 to T1, while the vellus hair density shows an evident decrease. The use of a molecule as cetirizine, with no notable side effects, makes possible a good compliance by patients. CONCLUSION: Our results have shown that topical cetirizine 1% is responsible for a significant improvement of the initial framework of AGA.

Dermoscopy and methyl aminolevulinate: A study for detection and evaluation of field cancerization.

Actinic keratosis (AK) is a keratinocyte intraepidermal neoplasia UV light-induced that frequently appears in sun-exposed areas of the skin. Although historically AK was defined as "precancerous", actually it is considered as the earliest stage of squamous cell carcinoma (SCC) in situ. Since AKs can progress into invasive SCC, their treatment is recommended. AKs rarely develop as a single lesion; usually multiple lesions commonly affect an entire area of chronically actinic damaged skin. This has led to the concept of "field cancerization", an area chronically sun-exposed that surrounds peripherally visible lesions, in which are individualized subclinical alterations. One of the main principles endpoint in the management of AKs is the evaluation and the treatment of field cancerization. In this view, in order to detect and quantify field cancerization, we employed a method based on the topical application of methyl aminolevulinate (MAL) and the detection of the fluorescence emitted by its metabolite Protoporphyrin IX (PpIX); then, considering the extension and the intensity of measured fluorescence, we create a score of field cancerization. The results show that patients underwent to daylight PDT had a reduction of total score, from T0 to T2. Whereas in the group untreated we observed a stability of total score or a slightly worse. So, the method and the score used allows to evaluate with a good approximation the dimension of field cancerization and show the modification of it after treatment.

A case of Scalp Rosacea treated with low dose doxycycline and probiotic therapy and literature review on therapeutic options.

Rosacea is a common chronic inflammatory disorder showing a wide range of clinical features such as telangiectasia, erythema, papules, and pustules primarily involving the central part of face (forehead, cheeks and nose) although extra facial manifestation have been described. We describe a case of rosacea with predominant scalp involvement successfully treated with a 8-week-course of doxycycline 40 mg once a day and probiotic therapy twice a day (Bifidobacterium breve BR03, Lactobacillus salivarius LS01 1 × 10(9) UFC/dose).

Cutaneous manifestations and gastrointestinal disorders: Report of two emblematic cases.

Gastrointestinal (GI) diseases, such as inflammatory bowel diseases (IBD), can manifest themselves with intestinal and extra-intestinal symptoms. Among the latter, cutaneous manifestations, such as pyoderma gangraenosum (PG) and metastatic Crohn's disease (MCD), represent a possible onset of IBD, with or without simultaneous bowel alterations. In such cases, intestinal and skin lesions are supported by the same immune-mediated mechanism. We hereby report two cases of patients with skin manifestations together with signs and symptoms suggestive of IBD. IBD and some skin lesions arise from the same immune-mediated mechanism. A multidisciplinary approach to these immune-mediated diseases is needed for an early and correct diagnosis, which in turn may lead to the use of the right drug avoiding useless treatment.

High prevalence of gluten sensitivity in a cohort of patients with undifferentiated connective tissue disease.

OBJECTIVES: The aim of this study was to investigate if co-morbid conditions as hepatitis C virus infection and celiac disease may be associated to undifferentiated connective tissue disease. METHODS: We studied retrospectively and prospectively 52 patients with diagnosis of undifferentiated connective tissue disease, subdivided, according to Vaz criteria, in systemic lupus erythematosus, systemic sclerosis and Sjögren's syndrome-like subgroups. Serological markers of celiac disease as anti-gliadin, anti-endomysium and anti-tissue transglutaminase antibodies were investigated. An esophagogastroduodenoscopy with duodenal biopsy and histological examination was proposed to patients with positive celiac disease serology. In addition antibodies directed to hepatitis C virus and total IgA-antibodies were investigated. RESULTS: Six patients (11,5%) were positive for celiac disease serological tests although two of them were asymptomatic. Four patients underwent an esophagogastroduodenoscopy, showing total or subtotal villous atrophy at duodenal biopsies. Hepatitis C virus serology was negative in all patients and none had IgA deficiency. 83% of celiac patients showed a scleroderma-like phenotype. We observed a statistically higher incidence of autoimmune symptoms in patients with gluten sensitivity. Fatigue and myalgia regressed early after the beginning of gluten-free diet. CONCLUSIONS: In our cohort of patients the prevalence of celiac disease was higher than that reported in the general population. We believe that all patients with diagnosis of undifferentiated connective tissue disease, especially those with a systemic sclerosis-like presentation, should be investigated for celiac disease, even in absence of gastrointestinal symptoms. Gluten-free diet should be early recommended to all patients having undifferentiated connective tissue disease and gluten sensitivity.

Conditions simulating androgenetic alopecia.

Androgenetic alopecia is a common form of hair loss, characterized by a progressive hair follicular miniaturization, caused by androgen hormones on a genetically susceptible hair follicle, in androgenic-dependent areas. Characteristic phenotype of androgenetic alopecia is also observed in many other hair disorders. These disorders are androgenetic-like diseases that cause many differential diagnosis or therapeutic error problems. The objective of this review was to systematically analyse the greatest number of conditions that mimic the AGA pattern and explain their disease pathogenesis.

Multiple skin ulcers due to Serratia marcescens in a immunocompetent patient.

Serratia marcescens is a species of gram negative bacillus, classified as a member of the Enterobacteriaceae, mainly involved in opportunistic infections, particulary in the hospital environment. Cutaneous infections have rarely reported in literature and are predominantly observed in elderly or in immunocompromised patients. The clinical manifestations of skin infections include granulomatous lesions, necrotizing fasciitis, nodules, cellulitis, ulcers, dermal abscesses. Infections caused by S. marcescens may be difficult to treat because of resistance to a variety of antibiotics, including ampicillin and first and second generation cephalosporins. Aminoglycosides have good activity against S. marcescens, but resistant strains have also been described. We report a very intriguing case of S. marcescens infection, in an immunocompetent 18-year-old man, causing multiple rounded ulcers of varying sizes, along with few pustular lesions that both clinically and histopathologically mimic a pyoderma gangrenosum (PG). This is a non infectious neutrophilic skin disorder, characterized by painful and rapidly progressing skin ulceration. According to our experience, we would strongly recommend to perform cultures of multiple skin ulcers resembling PG, even in young healthy patients, to ensure correct diagnosis and treatment, since resistant to conventional antibiotics bacteria such as S. marcescens may be the cause of these lesions, like in the case here reported.

Pemphigus vulgaris in a patient with arthritis and uveitis: successful treatment with immunosuppressive therapy and acyclovir.

A case of pemphigus vulgaris in a 41-year-old man with undifferentiated arthritis and uveitis is described. Histology of labial mucosa showed acantholytic, necrotic, and multinucleated giant keratinocytes having some nuclear inclusions suggestive of a virus infection. Specific serological tests revealed IgG positivity for HSV-1, CMV, and EBV, while real-time polymerase chain reaction assay from a biopsy of the mucosal lesion showed the presence of HSV-1/2 DNA. Treatment with prednisone, methotrexate, and acyclovir induced the complete remission of mucosal and joint symptoms, which then relapsed after interruption of antiviral therapy or immunosuppressive therapy. Therefore, a combined treatment with low doses of prednisone, methotrexate, and acyclovir was restarted and during 18 months of follow-up no recurrence was registered. Correlations between pemphigus and the herpes virus infection and also between autoimmune arthritis and herpetic agents have been well documented, but the exact role of the herpes virus in these disorders still needs further discussion. Our case strongly suggests that when autoimmune disorders do not respond to immunosuppressive agents, a viral infection should be suspected, researched, and treated.

Clinical, neurophysiological, and skin biopsy findings in peripheral neuropathy associated with hepatitis C virus-related cryoglobulinemia.

Hepatitis C virus (HCV)-related cryoglobulinemia commonly causes disabling complications including peripheral neuropathy and neuropathic pain. In this prospective clinical, neurophysiological, and skin biopsy study we aimed at assessing clinical characteristics and risk factors of peripheral neuropathy and neuropathic pain in patients with HCV-related cryoglobulinemia. We enrolled 69 consecutive patients with HCV-related cryoglobulinemia. We diagnosed neuropathic pain with the DN4 (Neuropathic Pain Diagnostic) questionnaire, and rated the various neuropathic pains with the Neuropathic Pain Symptom Inventory (NPSI). All patients underwent a standard nerve conduction study to assess Aß-fiber function, laser-evoked potentials to assess Aδ-fiber function, and skin biopsy to assess C-fiber terminals. Of the 69 patients studied, 47 had a peripheral neuropathy, and 29 had neuropathic pain. Patients with peripheral neuropathy were older than those without (P < 0.0001). While peripheral neuropathy was significantly associated with the duration of HCV infection (P < 0.01), it was unrelated to the duration of cryoglobulinemia and cryocrit (P > 0.5). The severity of peripheral neuropathy significantly correlated with the duration of HCV infection (P < 0.05). Laser-evoked potential amplitudes were significantly lower in patients with than in those without neuropathic pain (P < 0.05). Conversely, no difference was found in nerve conduction study and skin biopsy findings (P > 0.05). Our findings show that peripheral neuropathy is related to age and HCV infection, rather than to cryoglobulinemia, and neuropathic pain is associated with damage to nociceptive pathways as assessed with laser-evoked potentials; this might be useful for designing more effective clinical interventions for these common HCV related-cryoglobulinemia complications.

Cutaneous manifestations of systemic non-Hodgkin lymphomas (NHL): study and review of literature.

Systemic non-Hodgkin lymphomas are often accompanied by cutaneous manifestations, which are not always looked out for. Nevertheless, these alterations can be very important because their presence is lied to the clinical behaviour of the underlying malignancy, with an early recognition being fundamental. The aim of this study was to make order in this topic and propose a preliminary classification of the cutaneous manifestations associated with non-Hodgkin lymphomas. We performed a retrospective chart review of 62 haematological patients affected by non-Hodgkin systemic lymphomas with dermatological manifestations, who were evaluated from January 2007 to December 2011, and combined these results with a systematic review of Pub medical literature from 1937 to 2011 on this topic. A preliminary classification of these manifestations has been proposed, dividing them in specific and non-specific ones, along with a description of the clinical features and those cases observed in our department. A preliminary approach has been proposed for the study of these manifestations that could be helpful in understanding the biological behaviour and aid early recognition of a flare up in systemic non-Hodgkin lymphomas.

Optimization of systemic treatments for chronic plaque psoriasis. Recommendations for switching and transitioning.

AIM: The aim of this study was to provide practical recommendations for optimizing the use of conventional and biological systemic treatments for moderate-severe chronic plaque psoriasis, particularly in case of transitioning and switching. METHODS: A total number of 147 dermatologists from 33 different countries including Italy achieved consensus in providing practical recommendations for the use of conventional and biological treatments for moderate to severe psoriasis based on systematic literature review and/or expert opinion. RESULTS: In general, the continuous treatment regimen should be preferred in order to achieve a complete and long-term control of psoriasis. However, the treatment could be stopped or the dose reduced in case of complete disease clearance. A conventional drug could be associated to biological treatment in selected cases. Transitioning and/or switching could be considered in case of inefficacy or intolerance. A period of wash up is required if transitioning or switching is due to safety issues. CONCLUSION: This study provides practical suggestions for the optimal use of conventional and biological treatments for chronic plaque psoriasis.

Serum concentrations of IL-2, IL-6, IL-12 and TNF-α in patients with alopecia areata.

Alopecia areata (AA) has been represented as a restricted T cell-mediated autoimmune disease. Several studies have shown that cytokines may play an important role in its pathogenesis although many pathways exist. We investigated cytokine (IL-2, IL-6, IL-12, and TNFα) levels in peripheral blood mononuclear cell (PBMC) of 105 patients with different grade and duration of alopecia areata, to confirm that T-cell responses in AA is regulated via mechanisms of peripheral T-cell tolerance. We observed that IL-12 levels are higher for patients with bigger extensions and tend to increase according to the duration of the AA; TNFα instead, is more related to the gender of the patients and to the duration. Therefore abnormalities in cytokines production, showed by our results, may suggest that T-cell responses in AA scalp are closely regulated via mechanisms of peripheral T-cell tolerance and therefore confirm that this disease has an immuno-pathogenesis. Our aim is to shed light upon the complexity of AA underlying mechanisms and indicate pathways that may suggest future treatments.

Occurrence of salivary gland tumours in two patients treated with biological agents.

We report two cases of salivary gland tumors arising in two psoriatic patients treated with an anti- TNF-alpha agent. A clear causal relationship could not be established, but the exceptional onset of a bilateral Warthin's tumor in one of these patients should be emphasized.

Ehlers-Danlos syndrome: case report and an electron microscopy study.

Ehlers-Danlos syndrome (EDS) type III is a inherited connective tissue disorders characterized by extensibility of the skin, hypermobility of the joints, chronic pain, tissue fragility, easy bruising, and delayed wound healing with result of atrophic scars. The patients report commonly a history of recurrent dislocations of the shoulders and knees after low-impact trauma, chronic joint pain, and early osteoarthritis, which lead to diagnosis. The pathogenesis of this condition is unknown, and the diagnosis is generally made in adult age, based only on clinical criteria. In this report, we describe a case of a 50-year-old woman with a 30-year history of recurrent dislocations and atrophic scars. We performed diagnosis of EDS type III after a complete clinical and instrumental evaluation, comprising of histological and electron microscopic studies, that highlighted collagen abnormalities.

Comparitive effectiveness of finasteride vs Serenoa repens in male androgenetic alopecia: a two-year study.

The objective of this open label study is to determine the effectiveness of Serenoa repens in treating male androgenetic alopecia (AGA), by comparing its results with finasteride. For this purpose, we enrolled 100 male patients with clinically diagnosed mild to moderate AGA. One group received Serenoa repens 320 mg every day for 24 months, while the other received finasteride 1 mg every day for the same period. In order to assess the efficacy of the treatments, a score index based on the comparison of the global photos taken at the beginning (T0) and at the end (T24) of the treatment, was used. The results showed that only 38% of patients treated with Serenoa repens had an increase in hair growth, while 68% of those treated with finasteride noted an improvement. Moreover finasteride was more effective for more than half of the patients (33 of 50, i.e. 66%), with level II and III alopecia. We can summarize our results by observing that Serenoa repens could lead to an improvement of androgenetic alopecia, while finasteride confirmed its efficacy. We also clinically observed, that finasteride acts in both the front area and the vertex, while Serenoa repens prevalently in the vertex. Obviously other studies will be necessary to clarify the mechanisms that cause the different responses of these two treatments.
