Head and neck cancer is increasing globally owing to rising rates of tobacco use and human papillomavirus infection. Today, cancer is the leading cause of death and disabilities in developed countries and the second leading cause of death in countries with developing economies. Understanding the global landscape of head and neck cancer will empower oral and maxillofacial surgeons to play a critical role among patients and societal education regarding the importance of addressing modifiable risk factors and continuing to play an important role in the diagnosis and management of head and neck cancer.Addressing access to oral health care in many low- to middle-income countries is a complicated issue. Oral and maxillofacial surgeons may help engage with vulnerable populations through carefully planned dentoalveolar mission trips. The process of planning a mission includes selecting a population and identifying their unique needs, designing clinic layouts and workflows, team preparation, collection of supplies, fundraising, and advertising. During the mission, methods for protecting privacy, delivering treatment that is standard of care, and sanitation/sterilization options are reviewed. Ethical considerations include avoiding exploitation of vulnerable populations, offending local hosts, need for data collection, and long-term mission sustainability.To prepare global surgeons, academic institutions have created training programs that provide opportunities to develop foundational clinical knowledge, pursue academic inquiry, build surgical infrastructure and capacity, and become advocates and collaborators in resource-limited settings. Academic institutions can create a short course in global surgery, global surgery rotation, global surgery fellowship, or integrated global surgery residency. Global surgery training programs must account for ethics of global surgery engagement, sources of funding, structures for professional advancement, and trainee-appropriate partnerships. Global surgery training must include the establishment of accreditation systems, development of integrated training programs, and institutional investment in global surgery education.Global health has evolved to focus on reducing health inequity and obtaining the highest attainable standard of health for all people. To do this, a range of actors now pursue interventions and policy with an eye toward global targets that place strong emphasis on improving health systems. Within global health, global surgery has sought to delineate the burden of surgical disease and propose policy to improve access to surgery. click here Oral and maxillofacial surgery has been underrepresented in global health but has a vital role in reducing the global health inequity attributable to the impact of oral and craniofacial conditions.Introduction and objectives Very early (1-3 months) discontinuation of dual antiplatelet therapy (DAPT) has been recently proposed in percutaneous coronary interventions with modern drug-eluting stents (DES), with contrasting results. The aim of the present meta-analysis was to evaluate the prognostic impact of very short DAPT regimens vs the standard 12-month regimen in patients undergoing percutaneous coronary intervention with new DES. Methods Literature and main scientific session abstracts were searched for randomized clinical trials (RCT). The primary efficacy endpoint was mortality, and the primary safety endpoint was major bleeding events. A prespecified analysis was conducted according to the long-term antiplatelet agent. Results We included 5 RCTs, with a total of 30 621 patients; 49.97% were randomized to very short (1-3 months) DAPT, followed by aspirin or P2Y12I monotherapy. Shorter DAPT duration significantly reduced the rate of major bleeding (2% vs 3.1%, OR, 0.62; 95%CI, 0.46-0.84; P=.002; Phet=.02), but did not significantly condition overall mortality (1.3% vs 2%, OR, 0.97; 95%CI, 0.73-1.29; P=.84; Phet=.18). The reduction in bleeding events was even more significant in trials randomizing event-free patients at the time of DAPT discontinuation. The occurrence of myocardial infarction and stent thrombosis was similar between shorter vs standard 12-month DAPT. Conclusions Based on the current meta-analysis, a very short (1-3 months) period is associated with a significant reduction in major bleeding compared with the standard 12-month therapy, with no increase in major ischemic events and comparable survival.The complement system is an ancient arm of the innate immune system that plays important roles in pathogen recognition and elimination. Upon activation by microbes, complement opsonizes bacterial surfaces, recruits professional phagocytes, and causes bacteriolysis. Borreliella species are spirochetal bacteria that are transmitted to vertebrate hosts via infected Ixodes ticks and are the etiologic agents of Lyme disease. Pathogens that traffic in blood and other body fluids, like Borreliella, have evolved means to evade complement. Lyme disease spirochetes interfere with complement by producing a small arsenal of outer-surface lipoproteins that bind host complement components and manipulate their native activities. Here we review the current landscape of complement evasion by Lyme disease spirochetes and provide an update on recent discoveries.While modelling is an essential component for an understanding of the epidemiology of malaria, and for designing better control measures, it rarely considers the particular contexts encountered in emergency settings. By linking these situations with the transmission parameters our aim is to correct this bias and call for a better collaboration between relief actors.Annular epidermolytic ichthyosis is a rare subtype of epidermolytic ichthyosis that is characterized by erythematous, polycyclic, and migratory scaly plaques accompanied by palmoplantar keratoderma. This report presents the case of an 8-year-old girl who developed migratory, erythematous, scaly plaques associated with palmoplantar keratoderma. The initial hypothesis was erythrokeratodermia variabilis et progressiva; however, the finding of epidermolytic hyperkeratosis in histopathological examination led to the diagnosis of annular epidermolytic ichthyosis.
