Etiology of Chronic Leg Ulcers in a Dermatologic Wound Clinic: A Retrospective Observational Study.

Background: Chronic leg ulcers affect approximately 1% to 2% of the European population, with an increasing prevalence. The treatment of chronic wounds is a socioeconomical problem worldwide.

Purpose: The main purpose of the current investigation was to detect the etiology of leg ulcers treated in a dermatologic wound clinic from January 1, 2010, to December 31, 2019.

Topical Pharmacotherapy for Actinic Keratoses in Older Adults.

Actinic keratosis is caused by excessive lifetime sun exposure. It must be treated, regardless of thickness, because it is the biologic precursor of invasive squamous cell carcinoma, a potentially deadly malignancy. Physical ablative techniques such as cryotherapy, lasers, and curettage are the most used treatments for isolated lesions.

Impact of the COVID-19 pandemic and lockdown on the clinical response to dupilumab treatment and the psychological status of non-infected atopic patients.

Dupilumab is an effective treatment for atopic dermatitis and was found to improve results of clinician- and patient-oriented tests with relevant benefits across multiple domains related to the disease. To investigate the effects of significant psychological stress on clinician- and patient-oriented tests for severe AD patients treated with dupilumab. Patients were investigated before and during the COVID-19 pandemic and lockdown in a severely affected area.

A randomized split-face clinical trial of conventional vs indoor-daylight photodynamic therapy for the treatment of multiple actinic keratosis of the face and scalp and photoaging.

Background: Recently, indoor daylight photodynamic therapy (idl-PDT) has been developed; however, its efficacy and tolerability remain to be assessed.

Objective: This is a not-inferiority study to compare treatment outcomes of cPDT with a red LED lamp and idlPDT with a polychromatic white LED lamp in adult patients affected by symmetrical AKs of face and/or scalp.

Methods: In this comparative, intra-patient, split-face, randomized clinical trial forty-three adult patients were enrolled.

Sunlight-induced Painful Skin (Sun Pain): A New Differential Diagnosis in Photodermatology.

Photodermatoses are characterized by the development of skin eruptions following exposure to ultraviolet radiation or visible light. We report here the clinical findings and results of laboratory investigations and phototesting of 6 patients who experience debilitating and excruciating pain after sun exposure ("sun pain") in the absence of any skin eruption. Phototesting with sub-erythemal doses of ultraviolet A radiation triggered localized pain in 4 patients.

Clinical and dermoscopic changes of acquired melanocytic nevi of patients treated with afamelanotide.

Background: Afamelanotide (AFA) is a synthetic analogue of α-melanocyte-stimulating hormone that is approved for the treatment of patients affected by erythropoietic protoporphyria (EPP). AFA induces a "sun free" tanning and changes of acquired melanocytic nevi (AMN) that are generically described as "darkening".

Objectives: To assess clinical and dermoscopic AMN changes during AFA treatment.

A Short Cycle of Narrow-Band UVB Phototherapy in the Early Phase of Dupilumab Therapy Can Provide a Quicker Improvement of Severe Atopic Dermatitis.

Background: Since the best clinical response to dupilumab is achieved after 12-16 weeks, a combination therapy at the beginning of the treatment could be a helpful strategy to reach a faster response in patients with severe atopic dermatitis (AD).

Objectives: To quantify the benefit of a combination of dupilumab treatment with a short course of narrow-band ultraviolet B (NB-UVB) phototherapy.

Methods: In the present pilot study adult patients suffering from severe AD were enrolled with a 2:1 ratio to receive treatment with dupilumab alone or dupilumab plus NB-UVB phototherapy, for 12 weeks.

2020 European guideline on the management of genital molluscum contagiosum.

Molluscum contagiosum is a benign viral epidermal infection associated with high risk of transmission. The guideline is focused on the sexually transmitted molluscum contagiosum. The diagnosis is clinical with characteristic individual lesions, termed 'mollusca', seen as dome-shaped, smooth-surfaced, pearly, firm, skin-coloured, pink, yellow or white papules, 2 - 5 mm in diameter with central umbilication.

A Critical Reappraisal of Off-Label Use of Photodynamic Therapy for the Treatment of Non-Neoplastic Skin Conditions.

Background: In the past 30 years, topical photodynamic therapy (PDT) has been investigated for the treatment of a broad spectrum of cosmetic, inflammatory, and infectious skin conditions with variable, and often contrasting, results. However, the non-expert clinician may be in difficulty evaluating these results because different sensitizers, concentrations, formulations, light sources, and irradiation protocols have been used. In addition, many of these studies have poor quality design being case reports and uncontrolled studies of few cases.

Application of the 2017 criteria for vascular Ehlers-Danlos syndrome in 50 patients ascertained according to the Villefranche nosology.

Vascular Ehlers-Danlos syndrome (vEDS) is a rare inherited connective tissue disorder due to heterozygous pathogenic COL3A1 variants. Arterial, intestinal, and/or uterine fragility is the disease hallmark and results in reduced life expectancy. The clinical diagnosis is not always straightforward and patients' selection for molecular confirmation depends on the characteristics of applied criteria, that is, the Villefranche criteria (in use until 2017) and their revision according to the new EDS nosology.

Sun Exposure and Melanoma, Certainties and Weaknesses of the Present Knowledge.

Sun exposure is the main risk factor for cutaneous malignant melanoma (CMM). However, the UV-related pathogenetic mechanisms leading to CMM are far to be fully elucidated. In this paper we will focus on what we still don't fully know about the relationship between UVR and CMM.

Lung inhomogeneities and time course of ventilator-induced mechanical injuries.

Background: During mechanical ventilation, stress and strain may be locally multiplied in an inhomogeneous lung. The authors investigated whether, in healthy lungs, during high pressure/volume ventilation, injury begins at the interface of naturally inhomogeneous structures as visceral pleura, bronchi, vessels, and alveoli. The authors wished also to characterize the nature of the lesions (collapse vs.

Spatial orientation and mechanical properties of the human trachea: a computed tomography study.

Background: The literature generally describes the trachea as oriented toward the right and back, but there is very little detailed characterization. Therefore, the aim of this study was to precisely determine the spatial orientation and to better characterize the physical properties of the human trachea.

Methods: We analyzed lung computed tomography scans of 68 intubated and mechanically ventilated subjects suffering from acute lung injury/ARDS at airway pressures (Paw) of 5, 15, and 45 cm H2O.

Ferritin in dialysis-related arthropathy: could it be a possible biochemical indicator of articular chronic pain?

Background: The aim of our study was to evaluate laboratory data behaviour in two dialysis populations, with and without dialysis-related arthropathy and pain.

Methods: We produced an elaboration of more than 160,000 items of biochemical data of 25 dialysis-related arthropathy patients with chronic articular pain, and 25 patients asymptomatic for joint pain and arthropathy. The pain visual analogue scale (VAS) was employed for pain intensity determination.

Efficacy and tolerability of manidipine in the treatment of hypertension in patients with non-diabetic chronic kidney disease without glomerular disease. Prospective, randomized, double-blind study of parallel groups in comparison with enalapril.

Background: Calcium channel blockers (CCBs) are effective blood pressure lowering agents, giving rise to a prevalent dilation of the afferent arteriole. Manidipine, a long-lasting dihydropyridine CCB, demonstrates its action not only on the afferent arteriole, but also on the efferent one. This suggests theoretically a renoprotective effect in patients with chronic kidney diseases (CKD).

[Acute kidney failure in the patient with multiple myeloma. An analysis of the authors' personal cases].

The renal involvement in a multiple myeloma case (MM) has a frequency of 50% and causes a worsening of the disease with a survival average of about 12 months. Myeloma cast nephropathy (MCN) represents the more frequent clinic, histological form of nephropathy in course of MM and it evolves when monoclonal light free chain deposit in the renal tubules together with some other worse cases like dehydration and/or hypercalcaemia. We analyze here the clinical and renal histological features of eight patients treated for acute renal failure found in MCN in course of MM grade B.
