No clear guidelines are available for the management of pregnant women with condyloma acuminata, a human papillomavirus-associated benign neoplasm that develops in the genital tract. We performed a systematic review to gain a better understanding of the management of condyloma acuminata during pregnancy. In this review, we mainly focused on treatments. We searched PubMed, Google Scholar, and Web of Science to identify studies on the treatment of condyloma acuminata during pregnancy. Thirty articles met the inclusion criteria. The treatment methods described in the literature were laser therapy, cryotherapy, imiquimod, photodynamic therapy, trichloroacetic acid, and local hyperthermia. The most effective treatment remains unclear. Various factors must be considered when deciding how to treat. Based on our assessment of the literature, we recommend cryotherapy as the first-choice treatment and laser therapy as the second-choice treatment. Imiquimod can be considered in cases such as extensive condyloma acuminata that is not easily treated by cryotherapy or laser therapy. In such cases, sufficient informed consent must be obtained from the patient. Cryotherapy, laser therapy, and imiquimod have been administered during all 3 trimesters with no severe adverse effects, but we cautiously recommend reserving laser therapy until the third trimester because of the lower risk of recurrence before delivery. There are still many unclear points regarding the management of condyloma in pregnancy, and further research is needed.

Review
BACKGROUND
On 7th May 2022, human monkeypox was identified in the United Kingdom, a non-endemic zone, with subsequent multi-country outbreaks. About 6 weeks later, the European Centre for Disease Prevention and Control reported 1158 confirmed cases in non-endemic countries scattered within the European Economic Area (EEA), and a total of 1882 cases confirmed worldwide, inclusive of the EEA. These numbers are expected to increase with high alert and amplified surveillance established in non-endemic regions. In light of a looming epidemic, current understanding of the virus, and identification of gaps in the literature remain critical hence warranting a scoping review of available literature.
METHODS
Literature searches were performed through PubMed, SCOPUS, ScienceDirect and Hinari to identify studies eligible for inclusion in accordance with PRISMA guidelines.
RESULTS
Seventy-seven articles were included in the review. Majority of the cases were from the Central African clade (n = 29,905) versus the West African clade (n = 252). 6/16 articles that reported vaccination status stated that none of the cases were vaccinated. In the remaining articles, approximately 80%-96% cases were unvaccinated. It was noted that 4%-21% of the vaccinated individuals got infected. The secondary attack rate ranged from 0% to 10.2%, while the calculated pooled estimated case fatality rate was 8.7%.
CONCLUSION
This scoping review provides an extensive look at our current understanding on monkeypox disease. Further studies are needed to better understand its risk factors, genetics and natural history, in order for public health strategists to generate prevention strategies and management decisions.

BACKGROUND
The primary reported risk factors for herpes zoster (HZ) include increasing age and immunodeficiency, yet estimates of HZ risk by immunocompromising condition have not been well characterized. We undertook a systematic literature review to estimate the HZ risk in immunocompromised patients.
METHODS
We systematically reviewed studies that examined the risk of HZ and associated complications in adult patients with hematopoietic cell transplants (HCT), cancer, human immunodeficiency virus (HIV), and solid organ transplant (SOT). We identified studies in PubMed, Embase, Medline, Cochrane, Scopus, and clinicaltrials.gov that presented original data from the United States and were published after 1992. We assessed the risk of bias with Cochrane or Grading of Recommendations Assessment, Development, and Evaluation methods.
RESULTS
We identified and screened 3765 records and synthesized 34 studies with low or moderate risks of bias. Most studies that were included (32/34) reported at least 1 estimate of the HZ cumulative incidence (range, 0-41%). There were 12 studies that reported HZ incidences that varied widely within and between immunocompromised populations. Incidence estimates ranged from 9 to 92 HZ cases/1000 patient-years and were highest in HCT, followed by hematologic malignancies, SOT, and solid tumor malignancies, and were lowest in people living with HIV. Among 17 HCT studies, the absence of or use of antiviral prophylaxis at <1 year post-transplant was associated with a higher HZ incidence.
CONCLUSIONS
HZ was common among all immunocompromised populations studied, exceeding the expected HZ incidence among immunocompetent adults aged ≥60 years. Better evidence of the incidence of HZ complications and their severity in immunocompromised populations is needed to inform economic and HZ vaccine policies.

Review
BACKGROUND AND PURPOSE
Autonomic dysfunction has been occasionally described in varicella-zoster virus (VZV) infection, while few systematic reviews are available. We systematically review autonomic dysfunction due to VZV infection.
METHODS
This study followed the PRISMA guideline, and three databases were researched and included cross-sectional studies in full-length publications in the English language using appropriate search keywords.
RESULTS
A total of 102 articles were identified initially; finally 45 studies were used for review, comprising pupillomotor dysfunction in 4, sudomotor dysfunction in 2, cardiovascular dysfunction in 2, gastrointestinal dysfunction in 14, and urogenital dysfunction in 23. They can be summarized as (1) VZV infection rarely produces orthostatic hypotension, which involves diffuse sympathetic dysfunction by polyneuropathy. (2) In contrast, VZV infection produces dysfunction of the bladder and the bowel, which involves segmental parasympathetic or sympathetic dysfunction by dorsal root ganglionopathy.
CONCLUSIONS
Awareness of VZV-related autonomic dysfunction is important, because such patients may first visit a gastroenterology or urology clinic. Close collaboration among neurologists, dermatologists, gastroenterologists, and urologists is important to start early antiviral agents and maximize bowel and bladder care in such patients.

Meta-Analysis
OBJECTIVE
To evaluate whether testing positive for human papillomavirus (HPV) before treatment is associated with cervical cancer recurrence and disease-free, cancer-specific, and overall survival and to report the relationship of HPV to cervical cancer histology, stage, grade, tumor size, lymph node involvement, and treatment response.
DATA SOURCES
EMBASE and MEDLINE were searched from inception to January 27, 2022, with the use of MeSH terms and keywords relating to cervical cancer, HPV, and prognosis. ClinicalTrials.gov was not searched because of the nature of our review question.
METHODS OF STUDY SELECTION
Studies must have assessed HPV DNA or RNA in cervical pretreatment biopsies or cells from 20 or more patients with invasive cervical cancer followed up for any length of time and reported the effect of testing positive or negative for HPV on cervical cancer recurrence, disease-free survival, cancer-specific survival, or overall survival. We extracted data on HPV-detection methods, patient and tumor characteristics, and clinical outcomes.
TABULATION, INTEGRATION, AND RESULTS
Hazard ratios (HRs) and 95% CIs were pooled with a random-effects model. Meta-regression was performed to explore heterogeneity. Of 11,179 titles or abstracts and 474 full-text articles reviewed, 77 studies were included in the systematic review. Among these 77 studies, 30 reported on the relationship of HPV status to histology, 39 to cancer stage, 13 to tumor grade, 17 to tumor size, 23 to lymph node involvement, and four to treatment response. Testing positive for HPV was associated with better disease-free survival (HR 0.38, 95% CI 0.25-0.57; 15 studies with 2,564 cases), cancer-specific survival (HR 0.56, 95% CI 0.44-0.71; nine studies with 1,398 cases), and overall survival (HR 0.59, 95% CI 0.47-0.74; 36 studies with 9,169 cases), but not recurrence (HR 0.59, 95% CI 0.33-1.07; eight studies with 1,313 cases). Meta-regression revealed that the number of cases, tumor grade, specimen type, gene target, and HPV prevalence together explained 73.8% of the between-study heterogeneity.
CONCLUSION
This review indicates that HPV detectability in cervical cancer is associated with a better clinical prognosis.

Meta-Analysis Review
BACKGROUND
Cervical cancer (CC) is one of the most common gynecologic tumors among women around the world. Although the etiological role of human papillomavirus (HPV) in CC is well established, other factors in CC carcinogenesis remains unclear. Here, we performed a systematic review and meta-analysis to explore the association between infections of human herpesvirus (HHVs) and CC risk.
METHODS
Embase and PubMed databases were utilized to search the relevant studies. The revised JBI Critical Appraisal Tool was used to assess the quality of the included studies. Prevalence and odds ratios (ORs) with 95% confidence intervals (CI) were calculated to evaluate the association between viral infection and CC or precancerous cervical lesions (PCL).
RESULTS
Totally 67 eligible studies involving 7 different HHVs were included in meta-analysis. We found an increased risk of CC or PCL that was associated with the overall infection of HHVs (CC, OR = 2.74, 95% CI 2.13-3.53; PCL, OR = 1.95, 95% CI 1.58-2.41). Subgroup analysis showed a trend towards positive correlations between herpes simplex virus type 2 (HSV-2) infection and CC (OR = 3.01, 95% CI 2.24 to 4.04) or PCL (OR = 2.14, 95% CI 1.55 to 2.96), and the same is true between Epstein-Barr virus (EBV) infection and CC (OR = 4.89, 95% CI 2.18 to 10.96) or PCL (OR = 3.55, 95% CI 2.52 to 5.00). However, for HSV-1 and cytomegalovirus (HCMV), there was no association between viral infection and CC or PCL. By contrast, the roles of HHV-6, HHV-7, and Kaposi sarcoma-associated herpesvirus (KSHV) in cervical lesions were unclear due to the limited number of studies.
CONCLUSIONS
This study provided evidence that HHVs infection as a whole increase the risk of CC incidence. In addition, some types of HHVs such as EBV and HSV-2 may serve as potential targets in the development of new interventions or therapeutic strategies for cervical lesions.

Meta-Analysis Review
AIM
The aim of this study was to investigate the prevalence and potential association between infection with different herpes viruses and multiple sclerosis (MS).
METHODS
A systematic literature search was performed by finding relevant cross-sectional and case-control studies from a large online database. Heterogeneity, Odds ratio (OR), and corresponding 95% Confidence interval (CI) were applied to all studies by meta-analysis and forest plots. The analysis was performed using Stata Software v.14.
RESULTS
One hundred and thirty-four articles (289 datasets) were included in the meta-analysis, 128 (245 datasets) of which were case/control and the rest were cross-sectional. The pooled prevalence of all human herpes viruses among MS patients was 50% (95% CI: 45-55%; I2 = 96.91%). In subgroup analysis, the pooled prevalence of Herpes simplex virus (HSV), Varicella-zoster virus (VZV), Epstein-Barr virus (EBV), Cytomegalovirus (CMV), Human herpes virus 6 (HHV-6), Human herpes virus 7 (HHV-7), and Human herpes virus 8 (HHV-8) was 32%, 52%, 74%, 41%, 39% 28%, and 28%, respectively. An association was found between infection with human herpes viruses and MS [summary OR 2.07 (95% CI (1.80-2.37); I2 = 80%)].
CONCLUSION
The results of the present study showed that EBV, VZV, and HHV-6 infection are associated with multiple sclerosis and can be considered as potential risk factors for MS. Although the exact molecular mechanism of the role of herpes viruses in the development of MS is still unknown, it seems that molecular mimicry, the release of autoreactive antibodies, and inflammation in the CNS following viral infection can be important factors in the induction of MS.

Epstein-Barr virus (EBV) is an established pathogen linked to a wide range of lymphoproliferative disorders and solid tumors. Astrocytoma is one of the most frequent brain tumors in children, adolescents, and young adults. Astrocyte proliferation usually occurs after brain tissue aggression, which may be of different types, including viral infection. In particular, it has been suggested that EBV may play a role in astrocytoma pathogenesis. This article presents the summarized results of a systematic review of the literature on the relationship between EBV infection and astrocytoma pathophysiology. Although most studies detect the presence of EBV DNA in subsets of astrocytoma tumors, our conclusion is that currently, except for rare cases, there is no clear evidence that EBV plays a role in the development of astrocytoma.

Review
INTRODUCTION
Genital herpes is an infection with herpes simplex virus type 1 (HSV-1) or type 2 (HSV-2), and is among the most common sexually transmitted diseases.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of different oral antiviral treatments versus each other for a first episode of genital herpes in HIV-negative people? What are the effects of different antiviral treatments for genital herpes in HIV-positive people? We searched: Medline, Embase, The Cochrane Library, and other important databases up to October 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found eight studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: aciclovir, famciclovir, and valaciclovir.
