Peripheral Arterial

Given their severity and non-healing nature, diabetic chronic wounds are a significant concern to the 30.3 million Americans diagnosed with diabetes mellitus (2015). Peripheral arterial diseases, neuropathy, and infection contribute to the development of these wounds, which lead to an increased incidence of lower extremity amputations. Early recognition, debridement, offloading, and controlling infection are imperative for timely treatment. However, wound characterization and treatment are highly subjective and based largely on the experience of the treating clinician. Many wound dressings have been designed to address particular clinical presentations, but a prescriptive method is lacking for identifying the particular state of chronic, non-healing wounds. The authors suggest that recent developments in wound dressings and biosensing may allow for the quantitative, real-time representation of the wound environment, including exudate levels, pathogen concentrations, and tissue regeneration. Development of such sensing capability could enable more strategic, personalized care at the onset of ulceration and limit the infection leading to amputation. This review presents an overview of the pathophysiology of diabetic chronic wounds, a brief summary of biomaterial wound dressing treatment options, and biosensor development for biomarker sensing in the wound environment.

Wound therapy improves every year by developing new wound treatment options or by advancing already existing wound materials, for example, adding self-releasing analgesic drugs or growth factors to wound dressings, or by binding and inactivating excessive proteases. Also new dressing materials based on silk fibers and enhanced methods to reduce bacterial burden, for example, cold argon plasma, might help to fasten wound healing.

Status epilepticus is among the most dramatic of clinical presentations encountered by emergency room physicians, neurologists, neurosurgeons and intensivists. While progress in its management has been aided significantly with an increasing number of effective treatment options, improved diagnostic methods and more effective monitoring, poor outcomes and diagnostic failures are still frequently encountered. Refractory cases still carry significant morbidity and mortality rates, including poor cognitive outcomes. This review discusses basic pathophysiology and management of status epilepticus, neuroimaging findings, the role of continuous electroencephalogram monitoring and nonconvulsive status epilepticusas well as recent developments in treatment options for refractory cases.

Compression Bandages

Skin regeneration is a quite complex process. Epidermal differentiation alone takes about 30 days and is highly regulated. Wounds, especially chronic wounds, affect 2% to 3% of the elderly population and comprise a heterogeneous group of diseases. The prevailing reasons to develop skin wounds include venous and/or arterial circulatory disorders, diabetes, or constant pressure to the skin (decubitus). The hallmarks of modern wound treatment include debridement of dead tissue, disinfection, wound dressings that keep the wound moist but still allow air exchange, and compression bandages. Despite all these efforts there is still a huge treatment resistance and wounds will not heal. This calls for new and more efficient treatment options in combination with novel biocompatible skin scaffolds. Cold atmospheric pressure plasma (CAP) is such an innovative addition to the treatment armamentarium. In one CAP application, antimicrobial effects, wound acidification, enhanced microcirculations and cell stimulation can be achieved. It is evident that CAP treatment, in combination with novel bioengineered, biocompatible and biodegradable electrospun scaffolds, has the potential of fostering wound healing by promoting remodeling and epithelialization along such temporarily applied skin replacement scaffolds.

Renal Origin

Patients with critical limb ischaemia (CLI) constitute a subgroup of patients with particularly severe peripheral arterial occlusive disease (PAD). Treatment modalities for these patients that often exhibit multilevel lesions and severe vascular calcifications are complicated due to multiple comorbidities, i.e. of cardiac and vascular but also of renal origin. These need to be taken into consideration while planning treatment options. Although CLI is associated with considerably high morbidity and mortality rates, the clinical outcome of patients being subjected to revascularisation has improved substantially in recent years. This is mainly due to improved secondary prevention strategies as well as dedicated endovascular innovations for this most challenging patient cohort. The aim of this article is to provide a discussion of the contemporary treatment concepts for CLI patients with a focus on arterial revascularisation.

Advance care planning (ACP) is becoming more widely used as part of a drive to improve personalized care planning, but there is still more work to be done. Electronic Palliative Care Co-ordination systems (EPaCCs) have proved to be very effective in some areas but there are many barriers to be overcome before they are universally available. This chapter covers recent developments leading to the wider integration of ACP into primary care. These include policy initiatives, educational opportunities, information technology (IT), professional quality control and regulation, financial and business incentives, and the Compassionate Community movement. The chapter includes an overview of issues surrounding ACP in primary care and in the community.

Hybrid Nanofibers

The management of chronic wounds is challenging. The factors that impede wound healing include malnutrition, diseases (such as diabetes, cancer), and bacterial infection. Most of the presently utilized wound dressing materials suffer from severe limitations, including poor antibacterial and mechanical properties. Wound dressings formulated from the combination of biopolymers and synthetic polymers (i.e., poly (vinyl alcohol) or poly (ε-caprolactone) display interesting properties, including good biocompatibility, improved biodegradation, good mechanical properties and antimicrobial effects, promote tissue regeneration, etc. Formulation of these wound dressings via electrospinning technique is cost-effective, useful for uniform and continuous nanofibers with controllable pore structure, high porosity, excellent swelling capacity, good gaseous exchange, excellent cellular adhesion, and show a good capability to provide moisture and warmth environment for the accelerated wound healing process. Based on the above-mentioned outstanding properties of nanofibers and the unique properties of hybrid wound dressings prepared from poly (vinyl alcohol) and poly (ε-caprolactone), this review reports the in vitro and in vivo outcomes of the reported hybrid nanofibers.

Hepatocellular carcinoma (HCC) is a leading cause of global cancer death. Major etiologies of HCC relate to chronic viral infections as well as metabolic conditions. The survival rate of people with HCC is very low and has been attributed to late diagnosis with limited treatment options. Combining ultrasound and the biomarker alpha-fetoprotein (AFP) is currently one of the most widely used screening combinations for HCC. However, the clinical utility of AFP is controversial, and the frequency and operator-dependence of ultrasound lead to a variable degree of sensitivity and specificity across the globe. In this review, we summarize recent developments in the search for non-invasive serum biomarkers for early detection of HCC to improve prognosis and outcome for patients. We focus on tumor-associated protein markers, immune mediators (cytokines and chemokines), and micro-RNAs in serum or circulating extracellular vesicles and examine their potential for clinical application.

Abstract Background Squamous cell carcinoma (SCC) of the scrotum was the first malignancy known to be associated with exposure to an occupational carcinogen—in this case, soot trapped in the breeches of chimney sweeps. Better civil rules and regulations and the replacement of hearths with other forms of heating have rendered SCC of the scrotum a rarity. We report two cases of scrotal SCC with vastly differing clinical presentations and management. Case presentation Case 1 had T1 N0 M0 disease and presented with a small (< 2 cm), innocuous-looking, non-healing ulcer of eight years duration. A punch biopsy revealed a superficially invasive SCC confirmed on immunohistochemical profiling. A wide local excision of the lesion was subsequently performed. Follow-up at three years showed no signs of recurrence. Case 2 presented with T4 N1 M1 disease and rapidly progressing locally destructive mass. A punch biopsy of the scrotal lesion confirmed invasive moderately differentiated focally keratinising SCC. The metastatic evaluation confirmed the presence of metastatic, extensive para-aortic lymphadenopathy. He was managed with cisplatin-based chemoradiotherapy. Conclusion Early detection and management of patients with SCC of the scrotum are essential. If the diagnosis is delayed, treatment options become limited, and the prognosis is poor. Notwithstanding the rarity of this disease, multicentre trials are needed to provide more precise guidelines as to the optimal management of these patients.

AbstractInjectable filler treatments have increased in popularity because of enhanced safety profile and improved physical characteristics. ISAPS (International Society of Plastic Surgery) put out global data showing 3.7 million hyaluronic acid (HA) filler procedures in 2018, making it the second most often performed procedure in the world, after botulinum toxin. And these are only ‘those’ performed by qualified plastic surgeons. There was a concomitant increase in both the nonvascular and vascular complications, which coincided with the number and type of filler procedures performed. Filler complications were reviewed from existing literature, and an attempt was made to understand etiology, elucidate clinical features, and clarify optimum treatment strategies for each. Complications can be early or delayed in presentation, early consisting of injection site complications like bruising, edema, and hypersensitivity, Tyndall effect, and intravascular injection. Delayed complications included hypersensitivity type IV, acute infections like cellulitis, abscesses, and herpes and delayed ones like granulomas, biofilms, and atypical mycobacterial infections. These were analyzed and treatment options, protocols, and consensus guidelines were suggested. A clear understanding of facial anatomy, physical characteristics of all fillers used, early recognition, and treatment options of complications will ensure optimum outcomes.
