Review
Despite the scarcity of high quality cancer registries and lack of reliable mortality data, it is clear that human papillomavirus (HPV)-associated diseases, particularly cervical cancer, are major causes of morbidity and mortality in sub-Saharan Africa (SSA). Cervical cancer incidence rates in SSA are the highest in the world and the disease is the most common cause of cancer death among women in the region. The high incidence of cervical cancer is a consequence of the inability of most countries to either initiate or sustain cervical cancer prevention services. In addition, it appears that the prevalence of HPV in women with normal cytology is higher than in more developed areas of the world, at an average of 24%. There is, however, significant regional variation in SSA, with the highest incidence of HPV infection and cervical cancer found in Eastern and Western Africa. It is expected that, due to aging and growth of the population, but also to lack of access to appropriate prevention services and the concomitant human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) epidemic, cervical cancer incidence and mortality rates in SSA will rise over the next 20 years. HPV16 and 18 are the most common genotypes in cervical cancer in SSA, although other carcinogenic HPV types, such as HPV45 and 35, are also relatively more frequent compared with other world regions. Data on other HPV-related anogenital cancers including those of the vulva, vagina, anus, and penis, are limited. Genital warts are common and associated with HPV types 6 and 11. HIV infection increases incidence and prevalence of all HPV-associated diseases. Sociocultural determinants of HPV-related disease, as well as the impact of forces that result in social destabilization, demand further study. Strategies to reduce the excessive burden of HPV-related diseases in SSA include age-appropriate prophylactic HPV vaccination, cervical cancer prevention services for women of the reproductive ages, and control of HIV/AIDS. This article forms part of a regional report entitled "Comprehensive Control of HPV Infections and Related Diseases in the Sub-Saharan Africa Region" Vaccine Volume 31, Supplement 5, 2013. Updates of the progress in the field are presented in a separate monograph entitled "Comprehensive Control of HPV Infections and Related Diseases" Vaccine Volume 30, Supplement 5, 2012.

Review
Human Papillomavirus is the main cause of cervical cancer, including squamous cell carcinoma of the oropharynx, anus, rectum, penis, vagina, and vulva. In recent years, considerable effort has been made to control HPV-induced diseases using either prophylactic or therapeutic approaches. A critical review of the literature about the therapeutic Human Papillomavirus vaccine was performed to analyze its efficacy in the treatment of female lower genital tract lesions and its possible perspective application in clinical practice. The most important medical databases were consulted, and all papers published from 2000 until 2021 were considered. We retrieved a group of seven papers, reporting the role of anti HPV therapeutic vaccines against the L2 protein in the order of their efficacy and safety in female lower genital tract disease. In addition, the immune response due to vaccine administration was evaluated. The development of therapeutic vaccines represents an interesting challenge for the treatment of HPV infection of the lower genital tract. Literature data underline that the L2 protein may be an interesting and promising target in the development of therapeutic HPV vaccines, but the possible strengths and the unclear longevity of L2 immune responses are factors to be considered before clinical use.

Comparative Study
OBJECTIVE
To evaluate the impact of human papillomavirus (HPV) infections on the neovaginal and vulval tissues of women who underwent surgical treatment for Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome.
DESIGN
Multicenter observational study.
SETTING
University and community hospitals.
PATIENT(S)
Thirty-three women who had previously undergone neovagina reconstruction due to MRKH and who were referred to our centers for the evaluation and treatment of HPV neovaginal/vulval-related lesions.
INTERVENTION(S)
HPV infections were confirmed by polymerase chain reaction analysis or hybrid capture 2 tests; the patients underwent vaginoscopy, pap smear, and biopsy of the lesion and were treated by laser vaporization. Follow-up was conducted for 5 years.
MAIN OUTCOME MEASURE(S)
HPV-related neovaginal/vulval lesions, HPV testing, follow-up, recurrence rate.
RESULT(S)
Seventeen patients showed vulval lesions, and 16 patients neovaginal lesions. HPV testing results were positive for low-risk HPVs in 27 patients and high-risk HPVs in six patients. All the vulval lesions were condylomata, whereas 10 neovaginal lesions were condylomata, three were vaginal intraepithelial neoplasia (VAIN) degree 1, two were VAIN degree 2, and one was an adenocarcinoma. Eight patients were lost to follow-up. Twenty patients tested positive for an HPV infection, and seven patients (28%) had a recurrence of the lesion in the follow-up time.
CONCLUSION(S)
Patients who underwent neovagina reconstruction have sexual relationships and are HPV exposed. These patients should be evaluated after surgery for HPV infections to prevent HPV-related diseases and cancers.

Yonsei Medical Journal Aug 2002To report a rare case of vulvar myiasis caused by Wohlfartia magnifica, including clinical and microscopic observations.
BACKGROUND
To report a rare case of vulvar myiasis caused by Wohlfartia magnifica, including clinical and microscopic observations.
CASE
A vulvar lesion was found in a 31-year old married female villager with the history of dropping fly larvae from vulva, vulvar pain and itching sensation. The larvae were identified as the species of Wohlfartia magnifica. The lesion was washed with batticon over a period of five days and the patient was discharged.
CONCLUSION
Vulvar myiasis should be considered in the differential diagnosis of genital lesions. The diagnosis can be easily established based on microscopic features of the maggots, especially those relating to stigma structures.

BACKGROUND
Human papillomavirus (HPV) infection is a pre-requisite for cervical cancer, which represents the third most common cancer among women worldwide. A causal relationship also exists between HPV and cancer in other areas of the female reproductive system including the vagina and vulva. Whilst the incidence of vaginal cancer in the UK has remained relatively stable over the past 25 years, vulval cancer rates are increasing. A body of literature exists on the epidemiology and aetiology of vaginal and vulval cancer, but little is known about the economic burden. The objective of this study was to quantify the costs of treating these cancers on the National Health Service (NHS) in England.
METHODS
Inpatient and outpatient episodes were derived from Hospital Episode Statistics (HES). Health Resource Group (HRG) tariffs and National Reference Costs were used to estimate the cost of treating pre-cancerous and invasive vaginal and vulval lesions in England.
RESULTS
The study showed that for the 5 years from 2009/2010 to 2014/2015 the total cost associated with pre-cancerous and invasive vaginal and vulval lesions was over £14 million per year on average (95% of which was attributed to inpatient costs). Vulval cancer accounted for the largest proportion; an estimated 60% of the total cost (£8.82 million). On average 4316 patients per year in England were admitted to hospital and 912 patients attended outpatient settings for pre-cancerous and invasive disease of the vagina and vulva.
CONCLUSION
The results indicate that vaginal and vulval cancer cost the English health care system over £14 million per year. Given the causal role of HPV in a proportion of these cancers, preventative measures such as the national HPV immunisation programme have the potential to reduce the economic burden. To ensure optimal use of NHS resources, it is important that future economic evaluations of such preventative measures consider the full burden of HPV related disease.

BACKGROUND
HPV infection causes several cancers which include cervical, vaginal, vulval, penile and oropharyngeal cancer (OPC). Understanding the burden of HPV-related cancers is important for guiding cancer prevention and treatment interventions.
METHODS
To inform policy, we analysed trends of age-standardised incidence (ASIR) and mortality (ASMR) rates for HPV-related head and neck (HNC) and anogenital cancers (AGC) in South Africa between 1994 and 2013.
RESULTS
A total of 1 028 330 incident cancers and 617 044 cancer-related deaths were reported during the study period. The overall ASIR (-5.5%) and ASMR (-2.2%) for HNC declined, in part related to the anti-smoking legislation. In contrast, incidence (2.9%) and mortality (0.8%) rates for AGC increased with the rising HIV prevalence. ASIR for oral cavity cancer (OCC: -6.3%) and laryngeal cancer (LC: -11.3%) declined, including mortality associated with these cancers (OCC:-1.9%, and LC:-2.6%). However, oropharyngeal cancer showed a slower rate of decline in ASIR (-4.4%) and ASMR did not change. Compared to women, ASIR and ASMR for HNC were 3-fold higher among men. ASIR for both anal (7.5%) and vulval cancer (16.1%) increased. Median age at diagnosis of vulval cancer declined by 18 years (p-value = 0.01). Mortality rates for anal (3.9%) and vulval (2.6%) cancer increased. ASIR (-3.2%) and ASMR (-2.0%) for penile cancer declined. Rates for vaginal cancer did not change.
CONCLUSIONS
Anal and vulval cancers have increased over the reporting period. There is need to continuously monitor trends of these cancers. Implementation of HPV vaccination could significantly reduce the burden of HPV-related cancers.

OBJECTIVES
Heat shock proteins (HSPs) are proteins involved in protein folding and maturation. HSP expression is induced by heat shock or other stressors including cellular damage and hypoxia. The major groups, which are classified based on their molecular weight, include HSP27, HSP40, HSP60, HSP70, HSP90, and large HSP (HSP110 and glucose-regulated protein 170). The comparison of heat shock proteins and TP53 expression is yet not well studied in both vulval lichen sclerosus and lichen planus. Our aim was to assess the HSP and TP53 gene expression in women suffering from LS or LP and compare it within these groups and also healthy controls.
MATERIAL AND METHODS
The inclusion criteria were willingness to donate vulval biopsies, not currently or in the prior two weeks received any local nor systemic treatment for vulval disorder, age > 18 years old. The exclusion criteria were lack of consent, current vaginal infection confirmed with microbiological studies, current local or systemic treatment for vulval disease. 45 consecutive women were recruited into the study. All appropriate vulval samples were process by genetic analysis.
RESULTS
The mean expression (± SD) of HPSA1A for controls was 5.52 ± 3.18, for LS was 7.44 ± 2.16 and for LP was 7.89 ± 2.48. The mean expression (± SD) of HPSA1B for controls was 6.54 ± 3.41, for LS was 9.94 ± 6.88 and for LP was 9.43 ± 2.31. The mean expression (± SD) of TP53 for controls was 9.11 ± 1.14, for LS was 9.94 ± 1.27 and for LP was 10.41 ± 2.00. HSPA1A expression was 3,8 higher in women with lichen sclerosus than in control group.
CONCLUSIONS
Heat shock protein-70 is more often expressed in LS than in healthy controls. HSP-70 not only supports tumor growth and metastasis, but on the other hand mat help to develop immune-driven treatment strategies.

Review
The burden of human papillomavirus (HPV)-related cancers worldwide is significant. Although the incidence of cervical cancer is decreasing due to cervical screening programmes, the incidences of oropharyngeal, anal and vulval cancers are increasing. The introduction of HPV vaccination programmes in many countries has had an impact on HPV infection rates but due to the time-lag from initial HPV infection to the development of invasive carcinoma, the impact on the incidence of HPV-related cancer will take more time to become evident. This review explores the common aspects of HPV-related cancers and how they differ from their HPV-negative counterparts, both clinically and molecularly. It also covers the implications this has on future treatment strategies, including the possible role of immunotherapy.

A group of Holstein first-calved heifers developed small pustules and ulcers on the vulva and in the vagina during the first 1-4 wk postpartum. The lesions varied from small red pinpoint foci to pustules and ulcers, 3-5 mm diameter. Some ulcers coalesced to form large ulcerated areas up to 15 mm diameter. In some animals, these ulcers progressed to become deep ulceration of the vaginal and vulvar mucosa with >50% of the mucosa involved. Vaginal biopsies from 4 heifers and vaginal individual swabs from 8 heifers for a combined sampling of 9 heifers were taken for clinical assessment. Six of the 9 heifers had parapoxvirus based on histopathology and/or PCR. Histologic examination of the biopsies of the pustules identified ballooning degeneration of the epithelium with degenerate epithelium containing eosinophilic intracytoplasmic inclusions consistent with a parapoxvirus in 3 of 4 biopsies. Testing for bovine herpesvirus 1, 2, and 4, bovine viral diarrhea virus, bovine papular stomatitis virus, and orf virus remained negative.
