Darier disease is an autosomal dominant disorder with hyperkeratotic papules affecting primarily seborrheic areas of the upper chest, back, forehead, scalp, nasolabial folds, ears, and, less frequently, the oral mucosa. A typical eruption consists of keratotic and crusted skin-colored papules and plaques. Pruritus occurs in 80% of patients, and pain is rare. Lesions can be triggered by exposure to ultraviolet light, heat, or stress. Secondary infections of the lesions are a common complication. A definitive diagnosis is obtained by a biopsy showing histological features such as acantholysis, suprabasal clefts, and "corps rond and grains". Here we present a 37-year-old woman admitted to the gynecology department with pruritic lesions she had noticed on her vulva and perineum for three months. A vulvar biopsy led to the diagnosis of Darier disease. She was referred to the dermatology department and treated with oral acitretin since systemic retinoids are offered as the first-line treatment of the disease.

STUDY OBJECTIVE
To review and characterize reports of vulval aphthous ulcers (VAUs) following COVID-19 vaccination in VigiBase, the World Health Organization global database of reported potential adverse effects of medicinal products, to demonstrate the importance and power of case reports for rare suspected adverse reactions and to investigate whether they suggest a potential for COVID-19 vaccination to be a trigger METHODS: Cases reporting the Medical Dictionary for Regulatory Activities' (MedDRA) preferred term "Vulvovaginal ulceration" and related preferred terms in adolescent patients aged 12-17 years in association with any COVID-19 vaccine were extracted from VigiBase. The cases were clinically reviewed, and causality was assessed by applying the Bradford Hill criteria to the obtained case series.
RESULTS
As of June 30th, 2022, there were 444 reports for the selected Medical Dictionary for Regulatory Activities preferred terms following COVID-19 vaccination in VigiBase. Ninety-four de-duplicated reports concerned adolescent female patients. Thirty-seven cases were clinically consistent with the diagnosis of VAU. On causality assessment, the analyzed case series fulfilled 6 of the 9 Austen Bradford Hill criteria supporting a potential causal relationship.
CONCLUSION
VAUs can be perceived as a traumatic experience, especially in adolescent patients. There is, furthermore, a risk that the ulcers will be misdiagnosed, resulting in avoidable investigation and treatment burdens for patients. We communicate our findings to support the small number of published case reports and raise awareness of VAUs occurring in a temporal association with COVID-19 vaccination. Furthermore, our analysis supports observations about the value of case reports for the recognition and assessment of rare adverse events.

BACKGROUND
vulvar cancer, once predominantly diagnosed in older women, is increasingly being diagnosed in younger individuals, due to Human Papillomavirus (HPV) infection. Our study aimed to describe the epidemiological and histopathological aspects of vulvar cancer in Togo and its associated factors.
METHODS
This was a cross-sectional study, conducted on vulvar cancer cases histologically diagnosed at the Pathological Laboratory of Lomé over a period of 17-years (2005-2021). Parameters investigated included age, occupation, risk factors, sample nature, macroscopic tumor aspects, histological types, therapeutic intervenions, and prognostic outcomes.
RESULTS
A total of 32 cases of vulvar cancer were collected, yieding an annual frequency of 1.88 cases. The average age of the patients was 48±14.12 years with extremes of 27 years and 82 years. Housewives accounted for the largest proportion of cases (37.5%). Among the 32 cases, 27 had identifiable risk factors, with HPV infection being the most prevalentr (33.3%). The ulcero-budding aspect was most frequently observed, and squamous cell carcinoma was the most common histological type, with the majority being well differentiated (89.3%). Statistically significant associations were found between risk factors and histological types, risk factors and degrees of differentiation, as well as between histological types and good differentiation of vulvar cancers. The 3-year survival was estimated at 78.13%.
CONCLUSION
The incidence of vulvar cancer is increasing in Togo, particularly among young, primarily due to HPV infection.

Meta-Analysis Comparative Study Review
OBJECTIVE
There is no consensus on the best option for the management of Bartholin's gland abscesses. This systematic review and meta-analysis aimed to compare the Word catheter placement and marsupialization methods in the management of women with a cyst or abscess of the Bartholin's glands.
DATA SOURCES
The PubMed, Scopus, Embase, Web of Science, and Cochrane Library databases, as well as Google Scholar, were searched to retrieve articles published between January 1990 and July 2023, comparing the Word catheter treatment with marsupialization for women with a cyst or abscess of the Bartholin's glands.
STUDY SELECTION
Both observational studies and randomized controlled trials (RCTs) were included in this meta-analysis.
DATA EXTRACTION AND SYNTHESIS
After the review, out of 9 relevant articles, only 4 (2 observational studies and 2 RCTs) were included in this meta-analysis, providing the data of 735 patients (396 in the Word catheter group vs. 339 in the marsupialization group). The data was extracted from the selected articles, using a data extraction form. Comparison of the Word catheter and marsupialization methods suggested that the risk of recurrence was approximately 7.6% in the Word catheter group and 9.4% in the marsupialization group. The findings indicated no significant difference in the recurrence of cysts or abscesses when comparing the Word catheter treatment with marsupialization (odds ratio = 0.99, 95% confidence interval: 0.29-3.43, P = 0.990, I = 77%).
CONCLUSION
This meta-analysis found no significant difference in the rate of recurrence between the Word catheter and marsupialization methods. In general, marsupialization and Word catheter placement in the treatment of Bartholinitis seem to be equally effective.

Caucasus is known as one of the few biodiversity hotspots in Europe and is characterised by rich gastropod fauna while the nematode fauna in association with gastropods has remained largely understudied. Surveys conducted in 2019 and 2021 in the North Caucasus of the Russian Federation (Stavropol Upland and western and central parts of Krasnodar Krai) has revealed the presence of three new species of , a facultative parasite of land gastropods, and two species of obligate parasites, the intestinal parasite and a new, still undescribed species of a larval ectoparasite sp. The new associations of sp. and sp. with land gastropods were recorded for the first time in the Russian Federation. The new species of Dougherty, 1953 described here is based on the analysis of morphology and molecular studies of two distant and morphologically distinct strains, and n. sp. was characterised by females possessing a tail of about 95-100 μm long, broadly conical in shape in the and strains, with a rounded anterior part and a subulate terminal part as long as the former; prominent phasmids located at the mid-tail, equatorial vulva position, a lateral field of three ridges (four incisions), males with spicules featuring a hole at the distal tip, ensheathed infective juveniles with average length 717 μm in the strain and 771 μm in the strain, and exsheathed ones 644 μm and 682 μm, respectively. ITS-based phylogenetic analyses revealed that all species found in Ciscaucasia and Transcaucasia probably belong to two separate clades, with independent evolutionary histories of colonisation of this area. The entire Caucasus range area appears to serve as a biodiversity hotspot for the genus , presumably due to its complicated geological history and repeated isolation events for its terrestrial mollusc hosts.

BACKGROUND
Bacterial vaginosis is one of the most frequent vaginal tract infections during pregnancy. It is characterized by elevated vaginal pH, milky, creamy discharge, and an amine- or fishy-smelling odor.
STUDY AIM
Our study aimed to describe the characteristics and presenting manifestations of bacterial vaginosis in pregnant women.
METHODS
This cross-sectional analytical study included pregnant Saudi women who have been diagnosed with bacterial vaginosis. Data was collected using a self-administered questionnaire. We used the Statistical Package for Social Sciences (SPSS) version 26 for data management and statistical analysis.
RESULTS
The study included 456 women and found that 59.7% of people felt vulval itching, 7.7% reported swelling, 81% reported increased secretions, 62.5% reported dyspareunia, and 44.6% reported burning micturition. Thirty-one percent of individuals reported yellowish discharges, while 32.1% reported a foul odor. Older women with lower educational levels, who had vaginal itching and swelling, had significantly higher rates of burning urination.
CONCLUSION
Our study found that most of the presenting symptoms were significantly associated with dyspareunia and dysuria. The study also shows that nearly all the participants recovered with proper treatment. We recommend healthcare systems meticulously detect and cure bacterial vaginosis as it is a preventable cause of complicated pregnancy.

The aim of this study was to explore risk factors of recurrent bacterial vaginosis (RBV) among women of reproductive age. This cross-sectional study was carried out in real-world conditions. Women with RBV were selected, and simultaneously uncomplicated bacterial vaginosis (UBV) and those who underwent routine gynecological examination and had normal vaginal microflora were also recruited as the control. Totally, 316 participants were enrolled. Univariate analysis showed that unemployment, desserts, and wiping were related to UBV, while there was no definite relationship between education, high body mass index, smoking, sedentary lifestyle, and RBV or UBV. History of human papillomavirus infection, contraceptive methods, age at first sexual intercourse, and not cleaning vulva during sexual activity were connected with UBV, while the history of other vaginitis and number of sexual partners in the previous year were related to both RBV and UBV. Multivariate logistic regression analysis revealed that lower educational level increased the risk of suffering RBV. Interestingly, no smoking was a protective factor. Moreover, the absence of other vaginitis and an exclusive sexual partner could also weaken the risk of incurring RBV. These various adverse factors alter endocrine function and vaginal immunity, further leading to the recurrence of BV. It is necessary to take corresponding measures to avoid risk factors and to help lessening the prevalence of RBV among women of reproductive age.

Approximately 40% of vulvar squamous cell carcinoma (vSCC) cases are etiologically associated with high-risk human papillomaviruses (HPVs) of the alpha genera (α-HPV) that cause other anogenital cancers; however, the etiology of α-HPV-negative vSCC is poorly understood. HPVs of the beta genera (β-HPV) are risk factors for cutaneous squamous cell carcinoma (cSCC) and may be related to carcinomas originating in other cutaneous sites such as the vulva. In this study, we investigate the presence of β-HPVs, with an emphasis on p16-negative squamous lesions adjacent to vSCC. We subjected 28 vulvar squamous intraepithelial lesions adjacent to vSCC for comprehensive HPV genotyping, p16 and p53 immunohistochemistry, and consensus morphology review. Selected cases were subjected to qPCR and RNA in situ hybridization. Clinical data were obtained from medical records. β-HPV DNA was detected in eight of ten p16-negative lesions and three of fourteen p16-positive high-grade squamous intraepithelial lesions. The HPV DNA loads in vulvar squamous intraepithelial lesions ranged between less than 1 HPV DNA copy per cell to more than 100 HPV DNA copies per cell. This is, to the best of our knowledge, the first report of the association of p16-negative vulvar intraepithelial squamous lesions with detection of β-HPVs. These findings expand possible etiologic mechanisms that may contribute to p16-negative lesions of the vulva.

Meloidogyne naasi Franklin, 1965, the barley root-knot nematode, was originally found in field crops such as cereals, grasses, and sugar beet (Beta vulgaris L.) in England and Wales, (Franklin,1965). This nematode is one of the most significant root-knot nematodes impacting grains in European countries (Santos et al. 2020). Among root-knot nematode species, M. naasi, exhibits a distinct preference for grasses, with documented impacts on turfgrasses leading to reduced growth and vigor (Skantar et al., 2023; Cook and Yeates, 1993). In September 2022, root-knot nematode females and second-stage juveniles (J2) were recovered from roots of fowl manna grass, Glyceria striata (Lam.) Hitchc., during a nematode survey on natural vegetation at the Allegheny National Forest (41°30'13.8"N 79°09'46.2"W). Second-stage juvenile specimens were recovered from soil using sugar centrifugal flotation (Jenkins, 1964). Small galls with egg masses were dissected from fowl manna grass roots originally collected from the surveyed areas. In parallel, five plants of non-infected fowl manna grass were placed in a pot in the greenhouse using naturally nematode-infested soil collected from the same forested area. Small galls and female specimens recovered from these plants were dissected and processed for further analyses. Female and J2 were fixed in 3% formaldehyde solution and processed to glycerin (Golden, 1990; Hooper, 1970). The specimens were examined by light microscopy, morphometric measurements, and molecular markers, which included the D2-D3 region of the large ribosomal subunit 28S, and the rDNA internal transcribed spacer region (ITS). The perennial pattern of five females analyzed morphologically were consistent to the patterns observed for M. naasi. The perennial patterns had coarse ridges on the cuticle in dorsal region forming broken irregular lines around anal and phasmid area. We also noted a prominent fold that covered some of the anus and showed a curved line between vulval slit and phasmids, typical of M. naasi. The area around the vulval area had a few or no striae except for a few lines radiating from the vulval slit as in the original description. Measurements of ten J2 had a body length ranged between 380 and 410 µm, stylet 11-13 µm, tail 50-70 µm long with a hyaline tail terminus between 12-22 µm in length, 4 lines in the lateral field, a and c ratio between 29.23-35.91 and 5.79-7.9 fitting the original description by Franklin, 1965 and others populations found in the USA (Skantar et al., 2023). The matrix codes for the female specimes are A32, B324, C3, D3 and for J2's A2, B21, C123, D1, E3, F12 (Subbotin et al., 2021). The amplified DNA fragments were sequenced, resulting in an 726 bp fragment flanked by the D2-D3 primers (PP097762), while for the ITS primers an 634 bp fragment was obtained (PP092043). Both generated sequences for the specimens collected in Pennsylvania revealed >99% similarity to M. naasi sequences deposited at GenBank, and therefore, validating the morphological analyses. Based on both morphological and molecular analyses the specimens collected in the state of Pennsylvania were identified as M.naasi. To our knowledge, this is the first report of this species from this state and being associated with naturally infected fowl manna grass.

This study aimed to elucidate the differences in vulval squamous cell carcinomas (VSCC) based on the HPV infection status. The sequencing data GSE183454 which contains 23 VSCC samples based on its HPV infection status was obtained from the Gene Expression Omnibus (GEO) database. We comprehensively dissected the differences of genomic and tumour microenvironment (TME) immune cell infiltration landscapes between HPV + and HPV- VSCC. The potential molecular mechanisms of prognostic genes were explored by functional enrichment analysis. Five novel key molecules (SYCP2, SMC1B, RNF212, MAJIN and C14orf39) with significantly up-regulated expression in HPV + VSCC were identified while protein-protein interaction (PPI) networks were created upon Cytoscape software. Additionally, VSCC with up-regulated expression of these key molecules exhibited a significantly decreased TME immune cell infiltration. SYCP2 is overexpressed in HPV + VSCC and could be a candidate therapy target for further research.IMPACT STATEMENT VSCC are characterised by two aetiological pathways. The former occurs in the background of lichen sclerosus, while the latter is related to HPV infection. VSCC most commonly arises from the non-HPV related pathway portends worse prognosis than VSCC derived from HPV infection. Five key molecules are identified and significantly up-regulated in HPV + VSCC. In which, SYCP2 is overexpressed in HPV + VSCC and exhibited a significantly decreased TME immune cell infiltration. SYCP2 constant expression could be a potential biomarker of neoplasms associated with HPV and could be a candidate therapy target in VSCC especially HPV + VSCC for further research. SYCP2 could be a candidate therapy target in VSCC especially with HPV + for further research.
