An update on the current and emerging pharmacotherapies for basal cell carcinomas.

INTRODUCTION: Despite surgical approach is still the mainstay for basal cell carcinoma (BCC) management, several issues may limit the use of this technique, leading to the need for new treatments to offer patients a personalized approach. AREAS COVERED: A comprehensive review of the available and emerging pharmacologic strategies for BCC management, including mechanisms of action, and potential adverse effects, has been performed to provide with an up-to-date manuscript on the current treatment scenario of BCC. Globally, targeting the Sonic-Hedgehog pathway is one of the main mechanisms of action of currently investigated drugs. Other alternatives are based on the concept of an enhancement of the immune response such as immune checkpoint inhibitors, or intra-tumor treatments. EXPERT OPINION: Although low-risk BCCs are often treated with destructive methods or topical treatments, surgery is the mainstay of treatment for the majority of BCCs. However, several factors may limit the use of surgery in BCC management. Recently, major knowledge on BCCs pathogenesis has led to the development of effective and selective drugs. In our opinion, soon many drugs will be licensed, allowing clinicians to offer patients with BCC the right treatment at the right moment. Certainly, further studies are needed.

Chronic Urticaria in Older Adults: Treatment Considerations.

Chronic urticaria is characterized by recurrent wheals and/or angioedema lasting for more than 6 weeks. Chronic urticaria is an extremely disabling disease limiting daily activities, compromising patient quality of life, and frequently associated with psychiatric comorbidities (depression and/or anxiety). Unfortunately, there are still gaps in the knowledge regarding treatment in special populations, especially in older patients. Indeed, there are no specific recommendations for the management and treatment of chronic urticaria in older people; therefore, recommendations for the general population are used. However, the utilization of some medications may be complicated by potential concerns of comorbidities or polypharmacy. Currently, the diagnostic and therapeutic procedures for chronic urticaria in the older patient are the same as those indicated for other age groups. In particular, there is a limited number of blood chemistry investigations for spontaneous chronic urticaria and specific tests for inducible urticaria. With regard to therapy, second-generation anti-H1 antihistamines are used and, in recalcitrant cases, omalizumab (an anti-IgE monoclonal antibody) and possibly cyclosporine A are additional choices. Nonetheless, it should be underlined that in older patients the differential diagnosis can be more difficult, owing to the lower frequency of chronic urticaria and the likelihood of other pathologies that are peculiar for this age group and that can be included in the chronic urticaria differential diagnosis. As far as therapy is concerned, the physiological characteristics of these patients, the possible comorbidities, and the intake of other medications often require a very attentive drug selection for chronic urticaria compared with other age groups. The purpose of this narrative review is to provide an update on the epidemiology, clinical characteristics, and management of chronic urticaria in older patients.

Atypical Manifestations in Classic Kaposi Sarcoma: Case Series of Two Patients HIV - Negative.

BACKGROUND: Kaposi's sarcoma (KS) is a tumour of endothelial, blood and lymphatic cells, caused by an infection with human herpesvirus-8 (HHV-8). The skin lesions of KS, especially of the classical or Mediterranean variant (CKS), are represented by red-purple macules, plaques and nodules, localised mainly on the extremities. CASE REPORT: This case series intend to describe multifocal atypical kaposian manifestations in two HIV negative subjects, affected by CKS, treated with successful chemotherapy. CONCLUSIONS: Although atypical manifestations are extremely rare events, we suggest an accurate, objective examination because a prompt diagnosis can lead to a vital intervention in the patient's health and sometimes to the identification of the disease itself.
