BACKGROUND: Senegal ranks 15th in the world in incidence of cervical cancer, the number one cause of cancer mortality among women in this country. The estimated participation rate for cervical cancer screening throughout Senegal is very low (6.9% of women 18-69 years old), especially in rural areas and among older age groups (only 1.9% of women above the age of 40 years). There are no reliable estimates of the prevalence of cervical dysplasia or risk factors for cervical dysplasia specific to rural Senegal...

Immunochromatography (IC) is widely used to detect target molecules in biological fluids. Since this method can be performed without a special technique or device, IC is a convenient way to assess the existence of antibodies or pathogens such as viruses and bacteria, simply and quickly. In this study, we established an IC method to detect serum antibodies against oncogenic human papillomavirus (HPV)-16 and HPV-18 L1 proteins using recombinant L1 proteins produced by silkworms as antigens. Infection of oncogenic HPVs is a major risk factor of cervical cancer, which is one of the most common cancers in women worldwide...

To date, there are evidence-based guidelines available for cervical dysplasia diagnosed in pregnancy. Certain functional biomarkers have proven useful in the prediction of regressing and non-regressing cervical intraepithelial neoplasia (CIN) lesions in non-pregnant women. In the present study, Ki-67 and p16 immunostaining were evaluated in different grades of CIN lesions diagnosed in pregnant or non-pregnant women with the aim to identify any differences in order to better understand the behavior of CIN in pregnancy...

Over the last few decades, in reproductive medicine have allowed an improvement in the management and outcome of pregnancy in connective tissue diseases (CTD), such as Systemic progress Lupus Erythematosus and Antiphospholipid Syndrome; however, pregnancy and other related issues represent a crucial moment for patients and their family and some unmet needs are still present. In routine clinical practise, health professionals involved in the care of SLE and/or APS patients need to consider many aspects of the reproductive life of patients, involving not only pregnancy and family planning but also fertility, contraception, cancer surveillance and menopause...

As a result of the Human Papillomavirus (HPV) vaccination program, the prevalence of precancerous dysplasia and invasive cervical cancer has substantially decreased. In this brief report, we present a case of a young patient who was diagnosed with in situ adenocarcinoma of the cervix. This 30-year-old female had completed the HPV vaccination after she became sexually active and has been undergoing annual gynecological assessments, including clinical examination and Pap test, all of which had been negative. This year, her Pap test revealed a low grade squamous intraepithelial lesion (LGSIL) and additionally a colposcopy was performed...

BACKGROUND: Women living with HIV (WHIV) are disproportionately impacted by cervical dysplasia and cancer. The burden is greatest in low-income countries where limited or no access to screening exists. The goal of this study was to describe knowledge and intentions of WHIV towards HPV self-collection for cervical cancer screening, and to report on factors related to HPV positivity among women who participated in testing. METHODS: A validated survey was administered to 87 HIV positive women attending the Kisenyi Health Unit aged 30-69 years old, and data was abstracted from chart review...

Background Hemicrania continua (HC) -like headaches have been rarely reported as symptomatic headaches, including cases secondary to cervical artery dissection. Case series We present five cases of HC-like headaches following cervical artery dissection, in three cases with specific indomethacin response. In two cases, comorbidity of fibromuscular dysplasia (FMD) was noted. Conclusion Carotid artery dissection may result in an HC-like headache syndrome. A specific response to indomethacin does not rule out dissection as underlying pathology...

BACKGROUND: Adenocarcinoma in situ of the uterine cervix is a precursor to cervical adenocarcinoma and may coexist with both adenocarcinoma and high-grade squamous dysplasia (cervical intraepithelial neoplasia 2 and 3). Up to 60% of adenocarcinoma in situ lesions are detected incidentally following excisional biopsies performed for the treatment of cervical intraepithelial neoplasia 2/3. To date there are no data regarding risk factors for persisting or progressive cervical neoplasia in these patients...
