Abstract
Cervical cancer remains a significant disease in the United States. Although the human papillomavirus (HPV) vaccine has been approved for those aged 9-26 years and for some individuals up to age 45 years, there are many circumstances in which health care professionals may not know whether the vaccine should be recommended, such as for patients with previous infection, health care workers, and those older than age 26 years. This article highlights the evidence that the HPV vaccine is a safe and highly effective way to prevent cervical cancer, with the strongest predictor of vaccine uptake being practitioner recommendation.

Abstract
BACKGROUND Concerns regarding the aerosolized transmission of SARS-CoV-2 via SS have caused significant apprehension among surgeons related to the use of minimally invasive surgery (MIS) during the COVID19 pandemic. While a limited number of studies have previously demonstrated the presence of viral material in SS, no comprehensive systematic review exists on the subject of viral transmission in SS. Methods A systematic review of the literature was conducted as per PRISMA guidelines. MEDLINE, EMBASE, and CENTRAL databases were searched for publications reporting the primary outcome of the presence of viral particles in SS and secondary outcomes of indices suggesting transmission of viable virus particles in SS producing clinically important infection. All human, animal, and in vitro studies which used accepted analytic techniques for viral detection were included. A meta-analysis was not complete due to methodologic heterogeneity and inconsistent reporting of outcomes of interest. RESULTS 23 publications addressed the presence of viral components in SS, and 19 (83%) found the presence of viral particles in SS. 21 publications additionally studied the ability of SS to induce clinically relevant infection in host cells, with 9 (43%) demonstrating potential for viral transmission. CONCLUSION Evidence exists for viral transmission via SS. However, HPV remains the only virus with documented transmission to humans via SS. While meaningful translation into practical guidelines during the COVID pandemic remains challenging, no evidence exists to suggest increased risk in MIS.

Abstract
CONTEXT The coronavirus disease 2019 (COVID-19) pandemic raised concerns about the safety of laparoscopy due to the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diffusion in surgical smoke. Although no case of SARS-CoV-2 contagion related to surgical smoke has been reported, several international surgical societies recommended caution or even discouraged the use of a laparoscopic approach. OBJECTIVE To evaluate the risk of virus spread due to surgical smoke during surgical procedures. EVIDENCE ACQUISITION We searched PubMed and Scopus for eligible studies, including clinical and preclinical studies assessing the presence of any virus in the surgical smoke from any surgical procedure or experimental model. EVIDENCE SYNTHESIS We identified 24 studies. No study was found investigating SARS-CoV-2 or any other coronavirus. About other viruses, hepatitis B virus was identified in the surgical smoke collected during different laparoscopic surgeries (colorectal resections, gastrectomies, and hepatic wedge resections). Other clinical studies suggested a consistent risk of transmission for human papillomavirus (HPV) in the surgical treatments of HPV-related disease (mainly genital warts, laryngeal papillomas, or cutaneous lesions). Preclinical studies showed conflicting results, but HPV was shown to have a high risk of transmission. CONCLUSIONS Although all the available data come from different viruses, considering that the SARS-CoV-2 virus has been shown in blood and stools, the theoretical risk of virus diffusion through surgical smoke cannot be excluded. Specific clinical studies are needed to understand the effective presence of the virus in the surgical smoke of different surgical procedures and its concentration. Meanwhile, adoption of all the required protective strategies, including preoperative patient nasopharyngeal swab for COVID-19, seems mandatory. PATIENT SUMMARY In this systematic review, we looked at the risk of virus spread from surgical smoke exposure during surgery. Although no study was found investigating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or any other coronavirus, we found that the theoretical risk of virus diffusion through surgical smoke cannot be excluded.

Swerdlow BN. Surgical smoke and the anesthesia provider. J Anesth 2020; 34:575-584.

Abstract
Surgical smoke generated by use of electrosurgical units (ESUs), lasers, and ultrasonic scalpels constitutes a physical, chemical, and biological hazard for anesthesia personnel. Inhalation of particulate matter with inflammatory consequences, pulmonary injury from products of tissue pyrolysis, exposure to mutagens and carcinogens, and the transmission of human papillomavirus (HPV) and possibly other pathogens represent a spectrum of adverse effects associated with the occupational exposure to surgical plume. While adequate operating room ventilation and use of high filtration-efficiency masks offer some protection from these conditions, the most effective method of safeguarding against surgical smoke involves its removal with a dedicated smoke evacuation device (SED). Despite the fact that many professional and governmental agencies have endorsed widespread usage of SEDs, anesthesia providers have been largely silent on this subject, with few reports within the field of anesthesiology and perioperative medicine regarding these hazards. SED use is relatively infrequent in most surgeries, and this condition reflects surgeons' reluctance to employ these devices, likely resulting from lack of education and less than optimal technology. Anesthesia societies and academic centers can serve critical roles in advocating employment of SEDs in much the same way that they have supported perioperative smoking cessation.

Abstract
OBJECTIVES/HYPOTHESIS Human papillomavirus (HPV) is a DNA virus that causes cancer in multiple sites. Although sexual activity is the primary means of oropharyngeal HPV acquisition, studies suggest HPV transmission through occupational exposure from medical instruments and surgical fumes. We assess if aerosolization of HPV16 DNA via electrocautery places otolaryngologists at risk for exposure. STUDY DESIGN Animal and human laboratory model. METHODS Plasmid (pLXSN16E6E7) expressing HPV p16 E6/E7 genes was transformed into DH5α Escherichia coli cells using the heat shock method. Miniprep and maxiprep purification of transformed DNA with subsequent restriction enzyme double digestion confirmed presence of E6E7 fragment. We injected 2 μg plasmid DNA in 20 μL TE (Tris and ethylenediaminetetraacetic acid) buffer intradermally into freshly severed mouse tail then cauterized for 5 to 10 seconds. Generated fumes were collected through a suction tube fitted with Whatman filter paper. Filter paper was placed in 100 μL TE buffer. Additionally, six patients undergoing transoral robotic surgery for resection of oropharyngeal cancer were identified, three with p16-negative tumors and three with p16-positive tumors. Intraoperatively, Whatman filter paper was exposed to electrocautery fumes, then placed in 100 uL TE buffer. Additional samples were collected from the suction tubing and filter, the surgical mask of the surgeon at head of the bed, and the robot arm. RESULTS Samples were analyzed via polymerase chain reaction with an assay sensitivity of 1.5 ng E6E7 DNA. None of the patient or mouse tail samples yielded detectable HPV16 DNA in the electrocautery fumes. We did not detect HPV16 DNA on the surgical masks, suction apparatus, or robot arm intraoperatively. CONCLUSIONS There is likely minimal risk of occupational exposure to HPV16 via electrocautery fumes. LEVEL OF EVIDENCE NA Laryngoscope, 130:2366-2371, 2020.

HPV-Related Multiphenotypic Sinonasal Carcinoma: Four Cases that Expand the Morpho-Molecular Spectrum and Include Occupational Data. Head Neck Pathol 2019; 14:623-629. [PMID: 31571045 PMCID: PMC7413931 DOI: 10.1007/s12105-019-01079-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2019] [Accepted: 09/13/2019] [Indexed: 12/17/2022]
Abstract
HPV-related multiphenotypic sinonasal carcinoma (HMSC) is a recently described distinct tumor entity of the sinonasal tract associated with high-risk subtypes of human papilloma virus (HPV), predominantly type 33. The biological behavior seems to be less aggressive than the often high-grade, highly proliferative morphology implies; however, recurrences are frequent. Most of the cases present as polypoid tumors within the nasal cavity. Microscopic morphology frequently encompasses adenoid cystic-like features or features reminiscent of other salivary gland tumors. Here, we describe four cases of this rare entity, all observed in women. The polypoid tumors were within the nasal cavity, leading to obstruction, facial pain and epistaxis. The morphology was predominantly basaloid, solid and adenoid cystic-like in two of four cases, one with additional glomeruloid features. Another case showed basaloid tumor cells with prominent mature squamous differentiation and extensive keratinization. A single case showed a predominantly solid and reticular growth pattern. All cases were diffusely positive for p16 (100%), expressed SOX10, LEF-1 and partially S-100, and harbored HPV high-risk types 33, 56 (2×) and 82. No recurrences or metastases were detectable after 3-50 months of follow-up. Of note, three of four patients were nurses/nursing assistant. We expand the morphological spectrum by describing a glomeruloid growth pattern and extensive mature keratinization, and add HPV type 82 to the molecular spectrum. The finding of HMSC among predominantly nurses in our cohort warrants further epidemiological studies in larger cohorts.

Transmission of human papillomavirus DNA from patient to surgical masks, gloves and oral mucosa of medical personnel during treatment of laryngeal papillomas and genital warts. Eur Arch Otorhinolaryngol 2012; 269:2367-71.

Abstract
The risk of occupational human papillomavirus (HPV) transmission from patient to medical personnel during laser vaporization procedures remains controversial. The purpose of this study was to determine the risk of HPV transmission from the patient to the protective surgical masks, gloves and oral mucosa of medical personnel during the treatment of laryngeal papillomas and genital warts. The study involved five male patients scheduled for the surgical treatment of laryngeal papillomas, and five male patients undergoing carbon dioxide (CO(2)) laser treatment for urethral warts. Oral mucosa specimens were obtained from the study patients and the employees pre- and postoperatively. Samples were collected from the HPV-infected patient tissue, and from the surgical masks and gloves used by the employees. A total of 120 samples were analyzed for the presence of HPV DNA by PCR, using the degenerated MY09/11/HMB01 primers. After the papilloma procedures, the surgeons' gloves tested HPV positive in one of the five cases and those of the surgical nurse in three of the five cases. After the treatment of genital warts, HPV DNA corresponding to the patient tissue specimens was present in all the samples obtained from the surgical gloves of the operators. All oral mucosa samples obtained from 18 different employees tested HPV negative, as did the surgical mask specimens. According to our study, HPV may contaminate protective equipment, most of all surgical gloves, but transmission of HPV DNA to medical personnel is unlikely to occur provided that protective surgical gloves and masks are applied and disposed of properly.

Abstract
HPV infections in the anogenital region may have very heterogeneous clinical features. Most often typical papillomatous condylomata acuminata are observed that usually present no differential diagnostic difficulty. In contrast, the clinical findings of higher grade intraepithelial dysplasias with flat papules and erythematous/ eczematous lesions are often quite inconspicuous and hardly characteristic. The goal of therapy is to prevent further progression to carcinoma, removal of bothersome tumors and avoidance of complications. Surgical methods are preferentially employed for extensive lesions, unfavorable locations and higher grade dysplasia. Options include removal with scissors or scalpel, laser therapy and electrocautery. For purely intraepithelial alterations, superficial ablative techniques are usually preferable over excision. Further developments such as argon plasma coagulation reduce the risk of unwanted deep thermal destruction with the accompanying complications. The risks for the surgeon and the surgical team during treatment should also not be neglected. With consideration of all relevant aspects, the combination of different methods may reduce the risk of complications and frequency of recurrences. Due to the high recurrence rate independent of the selected therapy, consistent follow-up after primary therapy is crucial for the long-term success.

Abstract
Performance testing of two brands of surgical helmets indicated that their efficiency at in vivo filtration of sub–micrometer-sized particles is inadequate for their use as respirators. These helmets are not marketed for respiratory protection and should not be used alone for protection against severe acute respiratory syndrome when performing aerosol-generating procedures.
