Abstract
ZusammenfassungHintergrund und ZielsetzungDas Wissen über die Tiefeninfiltration bei nichtmelanozytärem Hautkrebs (NMSC) mithilfe präoperativer Sonographie könnte den Ärzten ermöglichen, den am besten geeigneten therapeutischen Ansatz zu wählen, unnötige Operationen und teure bildgebende Verfahren zu vermeiden und die Diagnose und Behandlung nicht zu verzögern. In unserer retrospektiven, monozentrischen Studie haben wir die Nützlichkeit des Hochfrequenzultraschalls (HFUS) zur Beurteilung der Tiefeninfiltration bei aurikulären und nasalen NMSC‐Fällen untersucht und die darauffolgende Änderung des therapeutischen Ansatzes bewertet.Patienten und MethodikIn 60 NMSC‐Fällen haben wir die Genauigkeit des HFUS bei der Erkennung von Knorpel‐ und Knocheninfiltration sowie die Korrelation sonographischer und histologischer Parameter beurteilt.ErgebnisseIn 16,6% der Fälle wurde präoperativ eine tiefe Knorpel‐/Knochenbeteiligung oder eine lokoregionale Erkrankung identifiziert, was zu einer geänderten therapeutischen Strategie mit radioimmunologischer Behandlung anstelle von Operation führte. In zwei Fällen identifizierte der präoperative HFUS eine lokale Knorpelinfiltration, was die Anzahl der chirurgischen Eingriffe reduzierte. Bei den verbleibenden 48 Läsionen ohne Tiefeninfiltration wurde eine Korrelation von > 99% zwischen der histologischen und sonographischen Tumoreindringtiefe gefunden (p <0.001).SchlussfolgerungenPräoperativer HFUS beeinflusst das therapeutische Vorgehen bei NMSC, indem es eine subklinische Beteiligung tieferer Strukturen erkennt, umfangreichere diagnostische Maßnahmen vermeidet, Kosten reduziert und die Qualität der Gesundheitsversorgung verbessert. HFUS sollte in der Dermatochirurgie vor der Tumorentfernung zur optimierten Therapie und zur verbesserten Patientenberatung eingesetzt werden.

Abstract
BACKGROUND AND OBJECTIVES The knowledge of depth infiltration in non-melanoma skin cancer (NMSC) using pre-operative ultrasound could enable clinicians to choose the most adequate therapeutic approach, avoiding unnecessary surgeries and expensive imaging methods, delaying diagnosis and treatment. Our single-center retrospective study determined the usefulness of high-frequency ultrasound (HFUS) for depth infiltration assessment in auricular and nasal NMSC and assessed the subsequent change in therapeutic approach. PATIENTS AND METHODS In 60 NMSC cases, we assessed the accuracy of HFUS in cartilaginous/bone infiltration detection as well as the correlation of sonographic and histological parameters. RESULTS In 16.6% of cases, a deep cartilaginous/bone involvement or locoregional disease was identified pre-operatively, resulting in a changed therapeutical scheme of radio-immunological treatment rather than surgery. In two cases, pre-operative HFUS identified local cartilage infiltration, reducing the number of surgical procedures. Forty-eight remaining lesions with no depth infiltration were excised; a correlation of > 99% between the histologic and sonographic tumor depth (p<0.001) was found. CONCLUSIONS Pre-surgical HFUS influences the therapeutic management in NMSC by detecting subclinical involvement of deeper structures, avoiding more extensive diagnostics, reducing costs, and improving healthcare quality. High-frequency ultrasound should be implemented in dermatosurgery before tumor excision for optimized therapy and improved patient counseling.

Abstract
The blood-brain barrier (BBB) is located at the interface between the vascular system and the brain parenchyma, and is responsible for communication with systemic circulation and peripheral tissues. During life, the BBB can be subjected to a wide range of perturbations or stresses that may be endogenous or exogenous, pathological or therapeutic, or intended or unintended. The risk factors for many diseases of the brain are multifactorial and involve perturbations that may occur simultaneously (e.g., two-hit model for Alzheimer's disease) and result in different outcomes. Therefore, it is important to understand the influence of individual perturbations on BBB function in isolation. Here we review the effects of eight perturbations: mechanical forces, temperature, electromagnetic radiation, hypoxia, endogenous factors, exogenous factors, chemical factors, and pathogens. While some perturbations may result in acute or chronic BBB disruption, many are also exploited for diagnostic or therapeutic purposes. The resultant outcome on BBB function depends on the dose (or magnitude) and duration of the perturbation. Homeostasis may be restored by self-repair, for example, via processes such as proliferation of affected cells or angiogenesis to create new vasculature. Transient or sustained BBB dysfunction may result in acute or pathological symptoms, for example, microhemorrhages or hypoperfusion. In more extreme cases, perturbations may lead to cytotoxicity and cell death, for example, through exposure to cytotoxic plaques.

Abstract
What points to consider when selecting a device for practicing dermatologic ultrasound is an excellent question. After we met the requisites published in the guidelines for practicing dermatologic ultrasound, it is necessary to consider the main objective of the use because it is not the same to be focused mostly on the avoidance of the puncture of important facial vessels such as the case of injectors of cosmetic fillers in comparison to the use of operators that need to deal with the diagnosis and monitoring of a wide range of dermatologic pathologies. Currently, a broad variety of ultrasound devices meets the minimum requirements for practicing these examinations in the market. Thus, small, portable, and high-end devices may present advantages and limitations that must be balanced according to the primary purposes and the budget. Moreover, the shape and footprint of the probes can make difficult or facilitate a dermatologic procedure. Other points to consider are the type of storage and the need for technical service. In summary, there are key points that we need to consider when we select a dermatologic ultrasound device in dermatology or aesthetics.

Abstract
Among the non-melanoma skin cancers (NMSC) the squamous cell carcinoma (SCC) is one of the most challenging for the surgeon. Local aggressiveness and a tendency to metastasize to regional lymph nodes characterize the biologic behavior. The variants locally advanced and metastatic require wide excision and node dissection. Such procedures can be extremely detrimental for patients. The limit of the surgery can be safely pushed forward with a multidisciplinary approach. The concept of skin oncoplastic surgery, the ablative procedures and the reconstructive options (skin graft, pedicled flap, microsurgical free flap) are discussed together with a literature review.
