Prevalence of Human Papillomavirus Infection and Cervical Abnormalities among Women Attending a Tertiary Care Center in Saudi Arabia over 2 Years.

Human papillomavirus (HPV) genotype distribution varies according to the assessment method and the population targeted. This study aimed to assess HPV infection prevalence in women aged 23 to 82 with abnormal cytology attending King Fahad Medical City (KFMC), Riyadh, Saudi Arabia, using retrospective data collected from January 2021 to December 2022. Cytological distribution included 155 samples of atypical squamous cells of undetermined significance (ASCUS) (n = 83), low-grade squamous intraepithelial lesion (LSIL) (n = 46), high-grade squamous intraepithelial lesion (HSIL) (n = 14), atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H) (n = 10), and squamous cell carcinoma (SCC) (n = 2). All samples were submitted to HPV detection and genotyping using Xpert HPV assay specimens. The most prevalent epithelial abnormalities were ASCUS (53.50%). Positive HPV infection results were observed in 52.9% of the samples. The highest prevalence of HPV genotypes, accounting for 31%, was attributed to the other high-risk genotypes, including 31, 33, 35, 39, 51, 52, 56, 58, 59, 66, and 68, followed by high-risk genotype 16, which counted in 11.60% of cases. Individuals who tested positive for HPV 16 were at a high risk of ASC-H, HSIL, and LSIL. Those testing positive for HPV 18-45 exhibited an elevated risk of LSIL, and those with positive results for other high-risk HPV genotypes were at an increased risk of ASCUS and LSIL, suggesting a low oncogenic potential. The results suggest that the percentage of association between samples with abnormal cervical presentation and negative high-risk HPV diagnosis is noticeably increasing. This underscores the need for effective screening programs and an understanding of the impact of specific HPV genotypes on cervical abnormalities.

HPV Vaccine Knowledge and Hesitancy Among Health Colleges' Students at a Saudi University.

Introduction: Human papillomavirus (HPV) infection is a widespread sexually transmitted infection linked to various types of cancer. Although vaccination against HPV is available, global HPV vaccination rates remain low. Aim: This study aimed to evaluate the awareness and knowledge of the HPV vaccine and to identify predictors associated with vaccine hesitancy among health college students at King Saud University, Saudi Arabia. Methods: A cross-sectional survey was distributed during December 2022 to students enrolled in health colleges. The survey link was randomly distributed via social media platforms and in-person interactions. The number of participants was 405 including both males and females. The data was analyzed using the Statistical Package for Social Sciences (SPSS). The correct response rate for all knowledge items was calculated, and they were stratified by gender and college. The association of vaccine hesitancy with sociodemographic characteristics was examined using logistic regression analysis. Results: The study found that approximately half of the students (49.9%) were aware of the HPV vaccine. However, only a small percentage of students answered all to all HPV knowledge items correctly. Additionally, only a small proportion (5.2%) reported receiving the vaccine. The overall HPV vaccine hesitancy was 59.1% (43.9% for female and 75.9% for male). The most common reasons for vaccine hesitancy was not knowing enough about it. Males were two times more likely than females to believe that they did not need the HPV vaccine. The odds for HPV vaccine hesitancy were greater among males and younger age groups compared to females and older age groups. Conclusion: This study underscores the importance of implementing university-wide interventions and educational campaigns to enhance awareness and knowledge of the HPV vaccine.

Awareness of Human Papillomavirus among Male and Female University Students in Saudi Arabia.

BACKGROUND: Human papillomavirus (HPV) is a common sexually transmitted infection globally. Investigating HPV awareness can reduce the burden of HPV-related cancers. AIMS: (1) Assessing HPV awareness and knowledge among health college students at King Saud University, (2) comparing these outcomes across sociodemographic characteristics. METHODS: A cross-sectional survey study was conducted from November to December 2022 and included 403 health college students. Associations of HPV awareness and knowledge with sociodemographic characteristics were assessed using logistic regression analysis and linear regression analysis, respectively. RESULTS: Only 60% of students were aware of HPV, with awareness higher among females, although their knowledge scores were comparable to males. The odds of awareness of HPV were greater among medical students compared to other colleges and among students belonging to older age groups compared to the younger age group (18-20). The odds of HPV awareness among hepatitis B vaccinated students were 2.10 times that among unvaccinated students (AOR = 2.10; 95% CI = 1.21, 3.64). CONCLUSIONS: The low level of HPV awareness among college students warrants the need for HPV educational campaigns to improve HPV awareness and to promote HPV vaccination in the community.

Monitoring the effect of TNF-alpha inhibitors on laboratory parameters and adverse effects in different diseases: a retrospective, single-center study.

BACKGROUND: The introduction of biological treatments has revolutionized the management of moderate-to-severe psoriasis. Multiple clinical trials have established the efficacy of biological agents in the treatment of moderate-to-severe psoriasis. Nevertheless, there are no clear indications for optimal monitoring intervals during treatment. OBJECTIVES: Collect and analyze laboratory evaluation data from patients receiving biological therapy to provide a better understanding of the need for laboratory investigations before and during treatment with biological agents, and to analyze adverse events and other factors. DESIGN: Retrospective cohort SETTINGS: Tertiary care center in Riyadh, Saudi Arabia. PATIENTS AND METHODS: Data were collected from the electronic medical records of patients attending the dermatology, rheumatology, and gastroenterology clinics from June 2014 to June 2019. The laboratory parameters of patients who have received one of the TNF-alpha inhibitors (adalimumab, etanercept, or infliximab) were collected starting at baseline and up to at least one year from treatment initiation. MAIN OUTCOME MEASURES: The time points at which patients developed significantly abnormal laboratory results during treatment with one of the TNF-alpha inhibitors. SAMPLE SIZE: 250 patients RESULTS: Most patients were treated with adalimumab (38.4%); a similar proportion (38%) with infliximab, whereas only 23.6% were treated with etanercept. The majority of the significant abnormal laboratory results occurred at baseline, 3-6 and 9-12 months. Most abnormalities were among patients using infliximab, followed by etanercept, and then adalimumab. The median number of laboratory abnormalities for dermatology patients was significantly lower than that for gastroenterology patients (P<.001), and for rheumatology patients (P=.002). CONCLUSIONS: Because dermatology patients showed a lower median number of laboratory abnormalities than patients treated by other specialties in our study, we believe that dermatology patients require less frequent laboratory monitoring. Therefore, we recommend laboratory evaluation at baseline, after 3-6 months, 1 year from the beginning of treatment, and annually thereafter for patients using TNF-alpha inhibitor agents. However, more frequent testing might be warranted according to patient comorbidities, concomitant medications, and physician judgment. LIMITATIONS: Single center and retrospective design. CONFLICT OF INTEREST: None.

Organoid systems to study the human female reproductive tract and pregnancy.

Both the proper functioning of the female reproductive tract (FRT) and normal placental development are essential for women's health, wellbeing, and pregnancy outcome. The study of the FRT in humans has been challenging due to limitations in the in vitro and in vivo tools available. Recent developments in 3D organoid technology that model the different regions of the FRT include organoids of the ovaries, fallopian tubes, endometrium and cervix, as well as placental trophoblast. These models are opening up new avenues to investigate the normal biology and pathology of the FRT. In this review, we discuss the advances, potential, and limitations of organoid cultures of the human FRT.

Clinical spectrum of neurofibromatosis type 1 among children in a tertiary care center.

OBJECTIVE: To identify the clinical and neuroradiological features of neurofibromatosis type 1 and the risk of malignancy in a pediatric age group. METHODS: This observational retrospective cohort study was conducted at King Saud University Medical City, Riyadh, Kingdom of Saudi Arabia, for the patients with neurofibromatosis type 1 who were seen and had follow up from January 2000 to January 2019. RESULTS: A total of 50 children were included. Approximately 90% of patients presented with cafe-au-lait macules, and 34% had skin-fold freckling. Moreover, 42% of the participants had a first-degree relative with neurofibromatosis type 1, and about a quarter presented with associated epilepsy. About 90% of the neuroradiological features were consistent with those of neurofibromatosis type 1. About 52% of the patients had one or multiple types of tumors, and 34% presented with optic pathway glioma. CONCLUSION: This study described clinical spectrum of neurofibromatosis type 1 among children. It showed also a higher percentage of tumors than previous studies.

Linear dermatomyofibroma over the nape of neck: a report of an unusual case and literature review.

Dermatomyofibroma is a rare cutaneous mesenchymal tumor of benign fibroblastic and myofibroblastic derivations. It predominantly affects young women, and it usually presents as a reddish-brown plaque or nodule, which is commonly located over the upper trunk. We report the case of a 41-year-old female patient who presented with progressive linear dermatomyofibroma over the nape of her neck. This case report expands the knowledge about the clinical and histopathological features of this rare, benign and cutaneous tumor.
