    Disseminated superficial porokeratosis and pyoderma gangrenosus

    Disseminated Superficial Actinic Porokeratosis (DSAP) is usually triggered by sun exposure. In some cases sun exposure is not essential and this skin disease is related to immunosuppression. Many associated diseases are described in the literature. We report a clinical case of a patient affected by pyoderma gangrenosum, who developed DSAP

    The Impact of Telemedicine in the Diagnosis of Erythema Migrans during the COVID Pandemic: A Comparison with In-Person Diagnosis in the Pre-COVID Era

    Get PDF
    Background: Erythema migrans (EM) is the hallmark manifestation of the Lyme borreliosis (LB), and therefore its presence and recognition are sufficient to make a diagnosis and to start proper antibiotic treatment to attempt to eradicate the infection. Methods: In this study we compared the clinical data of 439 patients who presented an EM either according to the diagnostic modality through physical assessment or through telemedicine. Conclusions: Our data clearly show that telemedicine for EM diagnosis is useful as it enables prompt administration of appropriate antibiotic therapy, which is critical to avoid complications, especially for neurologic and articular entities. Therefore, telemedicine is a tool that could be adopted for the diagnosis of Lyme disease both by specialized centers but also by general practitioners

    Improving the early diagnosis of early nodular melanoma: can we do better?

    Introduction: Cutaneous melanoma is the sixth most common malignant cancer in the USA. Among different subtypes of melanoma, nodular melanoma (NM) accounts about 14% of all cases but is responsible for more than 40% of melanoma deaths. Early diagnosis is the best method to improve melanoma prognosis. Unfortunately, early diagnosis of NM is particularly challenging given that patients often lack identifiable risk factors such as many moles or freckles. Moreover, early NM may mimic a range of benign skin lesions that are not routinely excised or biopsied in every day practice. For this reason, specific clinical and skin imaging clues have been proposed to improve early detection of NM.Areas covered: The review discusses about the noninvasive tools to diagnose thin melanoma, particularly NM. Expert commentary: Currently, dermatologists present a wide opportunity of diagnostic tools. Current data suggest that the early diagnosis of NM is a major challenge as the majority of early NM are symmetric, roundish, and lack specific pattern. Another promising strategy is based on recent data suggesting that artificial intelligence based on deep convolutional neural networking is able to outperform average dermatologist. Further research is necessary to validate the performance of this method in the real world and in the clinical setting

    Parry-Romberg syndrome: A case with a possible association with lyme disease

    Get PDF
    Parry-Romberg syndrome is an acquired slowly progressive disease characterized by an atrophy mostly involving half of the face. The pathogenesis of this disfiguring condition is still controversial. The relationship between Parry-Romberg syndrome and Lyme disease needs to be considered in depth. A 16-year-old woman from Albania presented with linear depressions of the right side of the face, clinically compatible with Parry-Romberg syndrome. She had a positive history of Lyme disease. Borrelia infection was confirmed by the positivity of PCR and the presence of IgM antibodies. The patient received intravenous penicillin and metronidazole for 14 days. After treatment and during a 2-year follow-up, the clinical disease progression was halted and the serological and microbiological tests for Borrelia burgdorferi sensu lato were negative. We cannot exclude a coincidence, however, of the bacteriological and serological evidence. Moreover, the interruption of the disease progression after the antibiotic therapy is difficult to ignore without claiming that this association is at least suggestive

    Innovative time-based separation procedures for civil RPAS integration

    Purpose: This paper aims to suggest feasible solutions to overcome the problem of unmanned aerial vehicles integration within the existing airspace. Design/methodology/approach: It envisages innovative time-based separation procedures that will enhance the integration in the future air traffic management (ATM) system of next generation of large remotely piloted aircraft system (RPAS). 4D navigation and dynamic mobile area concepts, both proposed in the framework of Single European Sky ATM Research program, are brought together to hypothesize innovative time-based separation procedures aiming at promoting integration of RPAS in the future ATM system. Findings: Benefits of proposed procedures, mainly evaluated in terms of volume reduction of segregated airspace, are quantitatively analyzed on the basis of realistic operational scenarios focusing on monitoring activities in both nominal and emergency conditions. Eventually, the major limits of time-based separation for RPAS are investigated. Practical implications: The implementation of the envisaged procedures will be a key enabler in RPAS integration in future ATM integration. Originality/value: In the current ATM scenario, separation of RPAS from air traffic is ensured by segregating a large amount of airspace areas with fixed dimensions, dramatically limiting the activities of these vehicles

    Use of noninvasive imaging in the management of skin cancer

    Get PDF
    6Purpose of review: To evaluate noninvasive imaging techniques in the management of skin cancers. Recent findings: In the last decades, a wide range of noninvasive imaging methods has been developed in the field of dermatooncology with the aim to detect and assess the several structural and molecular changes that characterize skin cancer development and progression. Summary: In this review, we discuss the current and emerging applications of noninvasive imaging approaches in skin cancer management, such as digital photography, dermoscopy, ultrasound sonography, reflectance confocal microscopy, optical coherence tomography, electrical impedance techniques, Raman spectroscopy, multispectral imaging, fluorescence imaging, and multispectral optoacustic tomography.partially_openopenGiuffrida, Roberta; Conforti, Claudio; Di Meo, Nicola; Deinlein, Teresa; Guida, Stefania; Zalaudek, IrisGiuffrida, Roberta; Conforti, Claudio; Di Meo, Nicola; Deinlein, Teresa; Guida, Stefania; Zalaudek, Iri

    Sporotrichoid Mycobacterium marinum infection in an elderly woman

    Get PDF
    We describe the case of an elderly woman who acquired a Mycobacterium marinum infection following skin exposure to the bacteria through a small wound on her right ring finger, obtained while preparing fish. The resultant sporotrichoid nodules of the right hand and the distal forearm, refractory to the initial therapy with doxycycline and rifampicin, were successfully treated with oral regimen of clarithromycin. \ua9 2015 by the article author(s)

    Integrating the concept of field cancerization in the classification and risk assessment of cutaneous squamous cell carcinoma: proposal for a new classification and terminology of keratinocyte skin cancer.

    Get PDF
    The term keratinocyte skin cancer (KC) stands as an umbrella for different stages within the progression of cutaneous squamous cell carcinoma (cSCC). 1\u20102 Its earliest form is named actinic keratosis (AK), while for the in\u2010situ form different synonyms, namely intraepidermal carcinoma (IEC), Bowen's Diseases (BD) and cutaneous squamous cell carcinoma in situ [cSCC(Tis)] or intraepithelial squamous cell carcinoma (iSCC) are used.3 Instead, cSCC is histopathologically classified into well, moderately and poorly differentiated subtypes
