RESUMO

ABSTRACT: Pyoderma gangrenosum (PG) is a neutrophilic dermatosis that is challenging to diagnose and treat. Clinicians frequently use fast-acting corticosteroids, which are subsequently combined with slower-acting immunosuppressants to progressively taper the corticosteroid dosage. Current research is focused on the use of monoclonal antibodies (mAbs) directed against target molecules involved in the pathogenesis of PG. However, available data on their efficacy are based on sporadic case reports and clinical experiences, so the authors aimed to evaluate the efficacy of risankizumab, an anti-interleukin-23 mAb, in the management of two complex PG cases. The authors enrolled two patients with PG who were already treated with immunosuppressive therapies. Their management was based on the off-label use of an mAb directed against the p19 subunit of interleukin-23: risankizumab. Patients received subcutaneous injections of 150 mg at the start of treatment, at week 4, and then every 10 weeks thereafter. Systemic therapy was combined with local management of ulcers, based on the principles of TIME (tissue, infection, moisture balance, and epithelialization) applied to the inflammatory and noninflammatory phases of PG. Clinical resolution was obtained at week 24 for patient 1 and week 16 for patient 2 and was maintained until week 40, without adverse effects or disease recurrence. These clinical cases demonstrate that risankizumab is a valid tool in terms of efficacy and safety for complicated cases of multirefractory PG when provided in parallel with local personalized wound management.

RESUMO

The most appropriate management of recurrent Hidradenitis Suppurativa (HS) lesions consists of wide surgical removal of the lesions with subsequent healing by second intention. Successful wound healing depends on the choice of an adequate wound dressing, targeted to the features of the wound.We enrolled 25 patients randomized into three groups according to the advanced dressing used in second intention healing of postsurgical wounds (standard therapy, an oxygen-enriched oil-based medical device with prolonged release of reactive oxygen species [ROS], ultra-portable negative pressure therapy). Data on wound size, clinical appearance of the wound bed, and pain experienced by the patient were collected twice a week for 4 weeksNo statistically significant differences were observed between the different groups evaluated. Oxygen-enriched oil-based medical device with prolonged release of ROS can be included in the principle of HS-tissue, inflammation, moisture, and epithelium (TIME).

RESUMO

Bacterial proliferation plays a well-known role in delayed tissue healing. To date, the presence of microorganisms on the wound bed can be detected by skin swabs or skin biopsies. A novel noninvasive fluorescence imaging device has recently allowed real-time detection of bacteria in different types of wounds through endogenous autofluorescence. The fluorescence signals detected by the device provide health workers with a visual indication of the presence, load, and distribution of bacteria. The aim of our study was to evaluate the level of bacterial colonization in perilesional skin of patients affected by venous leg ulcers treated with 2 different types of bandages: short stretch bandage and zinc oxide bandage. We conducted a monocentric prospective study, enrolling 30 patients with venous leg ulcers, divided into 2 groups: group A was treated with short stretch bandage and group B with zinc oxide bandage. A complete patient's assessment was performed once a week for 3 weeks. Levels of potentially harmful bacteria in perilesional skin were detected using a fluorescent device by 2 experienced operators on the frames taken at individual injuries, while pain was evaluated with the Numerical Rating Scale. After 3 weeks, we observed a reduction in the bacterial colonization levels of the perilesional skin by 68.67% for group A and 85.54% for group B. All the patients had a statistically significant reduction in bacterial load (P < .001), and a statistically significant difference was identified between the 2 groups (P = .043). No statistically significant differences were found between the 2 groups in terms of pain relief (P = .114). Our study demonstrated that the application of zinc oxide bandage provides a higher reduction in bacterial load perilesional skin. On the other hand, we found no difference between the 2 bandages in terms of pain symptom reduction.

RESUMO

Atopic dermatitis (AD) is a chronic multifactorial inflammatory disease characterized by intense itching and inflammatory eczematous lesions. Biological disease-modifying drugs, such as dupilumab are recommended for patients with moderate-to-severe AD, refractory to systemic immunosuppressive therapies. Disease monitoring is performed by clinical scores. Since 1970, however, the use of ultrasound and particularly high-frequency ultrasound (HFUS), has identified alterations in dermal echogenicity, called the subepidermal low-echogenic band (SLEB), that correlates with disease severity and response to treatment. We enrolled 18 patients with moderate-to-severe AD, divided into two groups: twelve patients in the dupilumab treatment (Group A) and six patients in standard treatment, from February 2019 to November 2019. We performed ultra-high frequency ultrasound (UHFUS) evaluation of lesional and non-lesional skin, focusing on SLEB average thicknesses measurement, epidermal thickness, and vascular signal in correlation with objective disease scores (EASI, IGA), patient's reported scores (Sleep Quality NRS and Itch NRS), and TEWL and corneometry at baseline (T0), after 1 month (T1) and 2 months (T2). The SLEB average thickness measurement, vascular signal, and epidermal thickness showed a statistically significant reduction in lesional skin of the biological treatment group and no significant reduction in non-lesional skin in both groups. In the lesional skin of the standard treatment group, only epidermal thickness showed a statistically significant reduction. Our study demonstrates that SLEB measurement, vascular signals, and epidermal thickness could be used as objective parameters in monitoring the AD treatment response, while the presence of SLEB in non-lesional skin could be used as a marker of subclinical inflammation and could predict development of clinical lesions, suggesting a pro-active therapy. Further follow-up and research are needed to clarify the association of SLEB decrease/disappearance with a reduction of flares/prolongment of the disease remission time.

RESUMO

Dermal hyaluronic acid (HA) fillers are used for nasolabial fold correction, but no study is still available on the use of ultra-high-frequency ultrasound (UHFUS) with 70 MHz probes for the evaluation of HA distribution and wrinkle amelioration. We selected 13 patients who received HA filler, evaluated before (Time (T) 0) and after injection (T1), and after 24 weeks (T2). The dermal thickness and distribution of HA were registered, as well as the Wrinkle Severity Rating Scale (WSRS), Global Aesthetic Improvement Scale (GAIS), and wrinkle 3D fullness. The UHFUS dermal thickness was increased by 11% for both sides at T1 and by 7.4% and 6.8% for the right and left side, respectively, at T2 (p < 0.01). The 3D wrinkle fullness showed a T1 increase (+0.59 cc and +0.79 cc for the right and left side, respectively) with a T2 maintenance of 45% of the T1 fullness (p-value < 0.001). The only clinical score significantly modified was WSRS, with a reduction of 56% at T1 and of 47.1% at T2 (p-value < 0.001). Our study then demonstrated the efficacy of UHFUS in the assessment of nasolabial fold correction, representing also the first multi-modal evaluation of HA persistence and its visual subsequent aesthetic results.

RESUMO

Pyoderma gangrenosum (PG) is a neutrophilic dermatological disease, whose pathogenesis is still poorly clarified. Because of the lack of validated criteria for diagnosis and response, PG treatment is still challenging and should be differentiated in the inflammatory and non-inflammatory phases. Our study aimed to provide a new semi-quantitative approach for PG diagnosis and monitoring, identifying ultra-high-frequency ultrasound (UHFUS) early biomarkers associated with the transition between the two phases. We enrolled 13 patients affected by painful PG lesions evaluated during the inflammatory phase (T0) and during the non-inflammatory phase (T1): pain was measured by the Visual Analogue Scale (VAS); clinical features were recorded through digital photography; epidermis and dermis ultrasound (US) characteristics were evaluated by UHFUS examination with a 70 MHz probe (Vevo MD® FUJIFILM VisualSonics). In T1 UHFUS examination, the presence of hyperechoic oval structures was lower compared to T0 (p value < 0.05). An hyperechogenic structure within the oval structure, suggestive of a hair tract, was evident in T0 and absent in T1 (p value < 0.05). In T0, blood vessels appear as U-shaped and V-shaped anechoic structures with a predominance of U-shaped vessels (p value < 0.05) compared to the more regular distribution found in T1. Finding early biomarkers of the transition from the inflammatory to the non-inflammatory phase could provide new insight in terms of therapeutic decision making and response monitoring. The differences found by this study suggest a potential use of UHFUS for the development of an objective standardized staging method. Further investigations will be necessary to confirm our preliminary results, thus providing a turning point in PG early detection, differential diagnosis and treatment monitoring.

RESUMO

Psoriatic onychopathy is one of the clinical presentations of psoriasis and a well-known risk factor for the development of psoriatic arthritis. High-frequency ultrasounds (HFUS > 20 MHz) have recently been used to evaluate the nail apparatus of healthy and psoriatic subjects. The aim of our study was to detect by means of ultra-high-frequency ultrasound (UHFUS 70-100 MHz) alterations of the nail bed and matrix in patients with psoriatic onychopathy and to monitor these parameters during the treatment with monoclonal antibody (mAb). We enrolled 10 patients with psoriatic onychopathy and naive to previous biologic therapies. Patients were evaluated at baseline, after 1 month and after 3 months from the beginning of mAb therapy by a complete clinical assessment and US evaluation. A UHFUS examination with a 70 MHz probe was performed on the thumbnail (I), the index fingernail (II) and the nail with greater clinical impairment (W). The following measurements were analyzed: nail plate thickness (A), nail bed thickness (B), nail insertion length (C), nail matrix length (D) and nail matrix thickness (E). Among the various parameters analyzed, some measures showed a statistically significant decrease with p-value < 0.05 (t0 WA = 0.52 mm vs. t2 WA = 0.42 mm; t0 WB = 2.8 mm vs. t2 WB = 2.4 mm; t0 WE = 0.76 mm vs. t2 WE = 0.64 mm; t0 IIA = 0.49 mm vs. t2 IIA = 0.39 mm). In conclusion, UHFUS could represent a viable imaging technique for the real-time evaluation and monitoring of psoriatic onychopathy, thus supporting the clinical parameters and revealing any subclinical signs of early drug response.

RESUMO

Background: To assess skin involvement in a cohort of patients with systemic sclerosis (SSc) by comparing results obtained from modified Rodnan skin score (mRSS), durometry and ultra-high frequency ultrasound (UHFUS). Methods: SSc patients were enrolled along with healthy controls (HC), assessing disease-specific characteristics. Five regions of interest were investigated in the non-dominant upper limb. Each patient underwent a rheumatological evaluation of the mRSS, dermatological measurement with a durometer, and radiological UHFUS assessment with a 70 MHz probe calculating the mean grayscale value (MGV). Results: Forty-seven SSc patients (87.2% female, mean age 56.4 years) and 15 HC comparable for age and sex were enrolled. Durometry showed a positive correlation with mRSS in most regions of interest (p = 0.025, ρ = 0.34 in mean). When performing UHFUS, SSc patients had a significantly thicker epidermal layer (p < 0.001) and lower epidermal MGV (p = 0.01) than HC in almost all the different regions of interest. Lower values of dermal MGV were found at the distal and intermediate phalanx (p < 0.01). No relationships were found between UHFUS results either with mRSS or durometry. Conclusions: UHFUS is an emergent tool for skin assessment in SSc, showing significant alterations concerning skin thickness and echogenicity when compared with HC. The lack of correlations between UHFUS and both mRSS and durometry suggests that these are not equivalent techniques but may represent complementary methods for a full non-invasive skin evaluation in SSc.

RESUMO

INTRODUCTION: Dubowitz syndrome is a rare genetic disease with only a few cases reported in the literature. It is characterized by growth retardation, microcephaly, facial dysmorphism and higher risk of developing cancer and cardiomyopathies. PG is an autoinflammatory disorder that causes painful ulcers to develop on the skin and has not been previously associated with Dubowitz syndrome. CASE PRESENTATION: The authors report the case of a 50-year-old female with Dubowitz syndrome who developed painful ulcerative lesions. An incisional biopsy was performed to rule out other diagnoses, and a subsequent clinical diagnosis of PG was made. The patient was treated with specialized wound dressings and oral glucocorticoids. The clinical picture improved consistently after 7 weeks of therapy. CONCLUSIONS: This case report, to the authors' knowledge, is the first to suggest a possible association between Dubowitz syndrome and PG and also to indicate an effective treatment.

RESUMO

BACKGROUND: The diagnosis of basal cell carcinoma (BCC) is based on clinical and dermoscopical features. In uncertain cases, innovative imaging techniques, such as reflectance confocal microscopy (RCM) and optical coherence tomography (OCT), have been used. The main limitation of these techniques is the inability to study deep margins. HFUS (high-frequency ultrasound) and the most recent UHFUS (ultra-high-frequency ultrasound) have been used in various applications in dermatology, but they are not yet routinely used in the diagnosis of BCC. A key point in clinical practice is to find an imaging technique that can help to reduce post-surgical recurrences with a careful presurgical assessment of the lesional margins. This technique should show high sensitivity, specificity, reproducibility and simplicity of execution. This concept is very important for the optimal management of patients who are often elderly and have many comorbidities. The aim of the paper is to analyse the characteristics of current imaging techniques and the studies in the literature on this topic. MATERIALS AND METHODS: The authors independently searched the MEDLINE, PubMed, Embase, Scopus, ScienceDirect and Cochrane Library databases for studies looking for non-invasive imaging techniques for the presurgical margin assessment of BCC. RESULTS: Preoperative study of the BCC subtype can help to obtain a complete excision with free margins. Different non-invasive imaging techniques have been studied for in vivo evaluation of tumour margins, comparing the histologic evaluation with a radical surgery. The possibility to study the lateral and deep margins would allow a reduction of recurrences and sparing of healthy tissue. CONCLUSION: HFUS and UHFUS represent the most promising, non-invasive techniques for the pre-operative study of BCC facilitating the characterization of vascularization, deep lateral margins and high-risk subtypes, although they are limited by insufficient literature unlike RCM and OCT.

RESUMO

Pyoderma gangrenosum (PG) is a neutrophilic inflammatory dermatosis, whose management still represents a clinical challenge due to frequent unresponsive cases. The aim of our study was to evaluate the efficacy of a novel, combined approach including local wound management, based on the principle of PG-TIME and a systemic therapy with an anti interleukin (IL)-17A monoclonal antibody (mAb). We presented a case of a 37-year-old female patient, affected by multi-refractory PG. The patient was treated with a combined approach of both local and systemic therapy. Wound clinical improvement was assessed by Wound Bed Score (WBS), wound size was evaluated through 3D camera laser scanner, and pain was evaluated with visual analog scale (VAS). After 52 weeks of therapy, the association of local wound management with ixekizumab 80 mg [160 mg at time (T) 0; 80 mg every 2 weeks until week 12; 80 mg every 4 weeks] allowed us to perform skin grafting and obtain complete wound healing. Our clinical case demonstrated the efficacy of a novel combination therapy for the treatment of recalcitrant PG based on IL-17 mAbs and local wound management built on the main features of PG-TIME.

RESUMO

OBJECTIVES: To provide a full characterization of proper palmar digital arteries (PPDA) in systemic sclerosis (SSc) with ultra-high frequency ultrasound (UHFUS), and to investigate possible relationships between digital macroangiopathy and microangiopathy. METHODS: SSc patients without active digital ulcers and healthy controls (HC) were enrolled. Each subject underwent UHFUS 70 MHz evaluation of PPDA from II to V fingers bilaterally, searching for vessel occlusion and measuring the thickness of the three arterial layers and the systolic-diastolic excursion range. Microcirculation was investigated with capillaroscopy and laser speckle contrast analysis (LASCA). RESULTS: Forty-six SSc patients (87% female, mean age 55.5 years) and 15 HC comparable for age and sex were enrolled. UHFUS in SSc revealed the occlusion of 124 (16.8%) PPDA, whereas in HC they were all patent. Considering a finger with at least one PPDA occluded as ultrasonographically pathological, 67.4% patients presented ≥1 pathological fingers. All three arterial layers were significantly thicker and excursion range significantly reduced in SSc than in HC (p<0.001 for all). Seventy-three percent of fingers previously affected by digital ulcers, were ultrasonographically pathological. Disease duration was directly correlated to the thickness of all three arterial layers. No significant correlations emerged between capillaroscopy or LASCA findings and UHFUS features. CONCLUSION: UHFUS allows the characterization of vasculopathic involvement of PPDA in SSc, also showing subclinical vasculopathy. The lack of correlations between UHFUS and capillaroscopy or LASCA likely mirrors non-overlapping vasculopathic processes. UHFUS evaluation of PPDA emerges as complementary to microcirculation assessment for a more accurate and complete characterization of SSc vasculopathy.

RESUMO

Traditional high-frequency ultrasound (HFUS; 20 MHz) is a non-invasive method used to study skin in vivo but is not able to measure skin thickness accurately and to identify the dermal-epidermal junction (DEJ). Ultra-high frequency ultrasound (UHFUS; 70-100 MHz) has sub-millimetre resolution comparable to histology. The aim of this study was to identify, by UHFUS, the DEJ and to describe skin differences in healthy individuals by providing a measure of skin thickness, based on age and gender. We also described the bullous pemphigoid lesion. We enrolled 42 patients divided into 2 groups: A and B. Group A included 32 healthy volunteers aged 22-74 years. Group B consisted of 10 patients with bullous pemphigoid. For each patient in group A, 8 ultrasound (US) clips by 70 MHz probe were performed at forehead, cheek, nose, forearm, abdomen, chest, back and leg. For each patient in group B, 5 US images were acquired at blisters roofs and edges. In each US image, we measured thickness of stratum corneum (α-ß), epidermis (α-γ) and epidermis plus dermis (α-δ). In both groups, we found the presence of 4 lines delimiting: the stratum corneum (the layer between α-line and ß-line), the epidermis (distance between α- and γ-line), and the boundary between dermis and subcutis (δ-line). The γ-line corresponds to the point of detachment of the bullae. The abdominal α-ß layer was thicker in males (p = 0.019) and α-δ thickness at cheeks (p < 0.001), chest (p = 0.007), back (p = 0.025) and forearm (p < 0.001). In females, α-γ thickness of the back was greater (p = 0.005). In old people compared to young, we noticed an increase of α-ß layer at forehead and chest (p = 0.014), an increase of α-γ layer at forearm (p = 0.001), back (p = 0.024) and leg (p = 0.010) and an increase of α-δ layer at forehead (p = 0.001) and nose (p = 0.049). UHFUS is an advanced imaging technique that can detect both the DEJ and the boundary between dermis and subcutaneous tissue so that epidermal and dermal thickness can be measured with good accuracy. Regarding gender and age, skin differences obtained with UHFUS were comparable to other non-invasive methods.

RESUMO

INTRODUCTION: Squamous cell carcinoma (SCC) is the second most prevalent malignant skin carcinoma. Bone infiltration is uncommon, and invasion of the dura mater and brain parenchyma is rare and possible only in the advanced stages of the disease. Treatment of advanced SCC is challenging and often requires the collaboration of a multidisciplinary team to provide local and systemic treatment. Management of advanced SCC of the scalp involving bones and meninges with brain exposure was described herein. CASE REPORT: An 85-year-old male presented with advanced SCC of the scalp. A vegetative and infiltrating neoplastic ulcer of the frontal and parietal regions with exposure of the brain and extensive meningeal and bone destruction was observed. Because of comorbidities and decisions made by the patient and his family, he did not undergo immunotherapy, radiotherapy, or other invasive treatments. The neoplastic tissue was covered by blood, fibrin, and bacterial colonization. The patient received palliative care in a wound healing clinic twice monthly for 1 year, and daily dressing changes were performed at home. Binding bacteria dressings, silver dressings, and absorbent dressings were used to control exudate and infection. Alginate was used to manage bleeding, and charcoal dressings were used to manage odor. The dressings were covered with gauze and bandage. Additionally, swabs were performed when signs of infection were present and targeted systemic antibiotic treatment administered. CONCLUSIONS: Squamous cell carcinoma rarely presents with a devastating and rapid evolution. In this case, the local approach was based on the TIME (tissue, inflammation/infection, moisture imbalance, epithelial edge advancement) concept, with special attention paid to the most significant features of neoplastic wounds (eg, pain, exudate, bleeding, odor). Despite the patient's serious conditions, he survived for a relatively long time.

RESUMO

A wide range of parasites can infest open wounds, or cause wounds due to the effects of the infestation. Parasitic infestations can involve the skin and subcutaneous tissues, with various clinical manifestations. In case of cutaneous wounds related to infestations, protozoa, helminths and arthropods are the main groups of parasites involved and emerging new aspects have been recently reported. Treating the wound correctly is fundamental in these patients in order to reduce the development of pathological scars and prevent complications. In particular, a gentle debridement for devitalized/infested tissue removal, the appropriate use of topical antiseptics and dressings such as hydrogel, hydrocolloids and antimicrobial dressings can be useful to control superinfections, moisture balance, inflammation and to promote edge proliferation.

RESUMO

The aims of our study were to evaluate with ultra-high-frequency ultrasound (UHFUS) the ultrasound features of congenital melanocytic nevi (CMNs) and malignant melanomas (MMs) arising in CMNs and the correlation between ultrasonographic thickness and histological thickness in MMs. We evaluated 10 patients with small-medium CMNs and 10 patients with MMs arising in small-medium CMNs. We collected patient's data, clinical and dermoscopic features. The UHFUS was performed using a 70 MHz frequency probe to study the ecostructure, shape and vascularization. Breslow thickness was compared with ultrasonographic thickness. In the MMs group the following dermoscopic features were described: hyperpigmentation (n = 9), regression area (n = 6), whitish-blue veil (n = 5), thickened network (n = 5), irregular globules (n = 3), inverse network (n = 2) and striae (n = 1). Hyperpigmentation (n = n = 9), thickened network (n = 7), irregular globules (n = 5), regression area (n = 5), striae (n = 1) and whitish-blue veil (n = 1) were found in the CMNs group. The multicomponent pattern was present in both MMs (n = 4) and in CMNs (n = 5). Moreover, the parameters indicative of suspected malignancy were variously combined in the two groups, without showing significant differences in the statistical analysis; with the exception of the blue veil that correlated with the diagnosis of MM. Ultrasonoghaphic vascularization was an ever-present parameter in MMs (100%), with high intensity of intratumoral signal, as opposed to CMNs. We also found a statistically significant correlation between ultrasound thickness and Breslow thickness. In the future, this technique could implement the diagnostic preoperative phase of MMs arising in CMNs in combination with standard clinical-dermatoscopic evaluation.

RESUMO

INTRODUCTION: Achilles tendon rupture is a common injury requiring surgical repair. Re-ruptures, infections, delayed wound healing, and hematomas have been reported postoperatively. OBJECTIVE: This case series described the use of ultraportable negative pressure wound therapy (NPWT) and compression bandaging following postoperative dehiscence of Achilles tendon repair. MATERIALS AND METHODS: Retrospective records were reviewed to identify patients who underwent wound management for Achilles tendon dehiscence between January 2014 and January 2018. Patient demographics, wound size at first and last visit, number of visits, and previous treatment data were extracted. Wound management included wound irrigation, surgical debridement, and application of silver dressings, as needed. Therapy was transitioned to ultraportable NPWT with twice-weekly dressing changes. When possible, patients with an ankle-brachial index greater than 0.8 received multilayer, multicomponent compression. Treatment response was evaluated using a wound imaging system at 2-week to 4-week intervals for a total of 24 weeks. RESULTS: Nine male patients with a mean age of 69.7 years presented for care. One patient sustained injury during sports activities, and the other 8 patients sustained injuries resulting from household accidents. Six patients achieved complete wound closure. Three patients achieved a mean 90% wound closure. No adverse effects were observed during treatment with NPWT and compression therapy. CONCLUSIONS: In the current study, ultraportable NPWT and compression bandaging were found to be effective in the management of wounds with critical local vascularity. Larger, randomized controlled studies are necessary to fully assess the potential clinical benefit of NPWT and compression therapy in the management of postoperative wounds of the Achilles tendon.
