The aim of this paper is to report a very rare case of müllerianosis (endosalpinx, endometrium, and endocervix) in a post-menopausal woman. Müllerianosis of the bladder is a very rare disease, which affects mainly the women of the reproductive age group, but with a good prognosis if the transitional bladder carcinoma is resolved. We present the case of a 64-year-old woman complaining of left lower abdomen pain, repeated lower and upper tract urinary infections, emergency urinary incontinence and hematuria...

γδ T cells act as a first line of defense against invading pathogens. However, despite their abundance in mucosal tissue, little information is available about their functionality in this compartment in the context of HIV/SIV infection. In this study, we evaluated the frequency, phenotype, and functionality of Vδ1 and Vδ2 T cells from blood, rectum, and the female reproductive tract (FRT) of rhesus macaques to determine whether these cells contribute to control of SIV infection. No alteration in the peripheral Vδ1/Vδ2 ratio in SIV-infected macaques was observed...

Immunohistochemistry is widely used to support a pathology diagnosis of cervical adenocarcinoma despite the absence of a systematic review and meta-analysis of the published data. This systematic review and meta-analysis was performed to investigate the sensitivity and specificity of immunohistochemistry biomarkers in the tissue-based diagnosis of cervical adenocarcinoma histotypes compared with normal endocervix and benign glandular lesions. The systematic review and meta-analysis used a PICOT framework and QUADAS-2 to evaluate the quality of included studies...

BACKGROUND: High risk (HR) human papilloma Virus (HPV) genotypes have been associated with cervical cancer. In Tanzania there is a limited data on the epidemiology of HPV and genotypes distribution among HIV infected women. Here we document varieties of HPV genotypes associated with cervical squamous intraepithelial lesions (SIL) among HIV- infected women at Bugando Medical Centre, Mwanza-Tanzania. METHODS: A cross sectional hospital based study involving HIV infected women was conducted between August and October, 2014...

P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), and multidrug resistance protein 4 (MRP4) are three efflux transporters that play key roles in the pharmacokinetics of antiretroviral drugs used in the pre-exposure prophylaxis of HIV sexual transmission. In this study, we investigated the expression, regulation, and function of these transporters in cervicovaginal tissues of a mouse model. Expression and regulation were examined using real-time RT-PCR and immunohistochemical staining, in the mouse tissues harvested at estrus and diestrus stages under natural cycling or after hormone synchronization...

Benign, premalignant, and malignant endocervical glandular lesions occasionally show a gastric phenotype. We report 2 cases of gastric-type adenocarcinoma in situ (AIS) of the endocervix, not associated with lobular endocervical glandular hyperplasia or gastric-type adenocarcinoma. Cytologically, both showed endocervical glands with slightly enlarged nuclei, distinctive nucleoli, pseudostratified strips, and intracytoplasmic golden yellow mucin. Histologically, both lesions were situated in preexisting endocervical glands and presented columnar cells with voluminous pale eosinophilic cytoplasm and evident nuclear atypia...

PROBLEM: The programmed death 1 (PD-1)/PD-L1 pathway regulates peripheral tolerance, immune responses, and is up-regulated in chronic viral infections, including HIV infection. However, expression of PD-1/PD-L1 on immune cells from the human female reproductive tract (FRT) and possible regulation by menopause and sex hormones are poorly understood. METHOD OF STUDY: PD-1/PD-L1 expression was analyzed on CD4(+) and CD8(+) T cells, CD163(+) macrophages, and CD11c(+) dendritic cells (DC) from endometrium (EM), endocervix (CX) and ectocervix (ECX)...

The endocervix plays an important role in providing appropriate protective mechanisms of the upper female reproductive tract (FRT) while at the same time providing the appropriate milieu for sperm transport. Hormone fluctuations throughout the menstrual cycle contribute to changes in the mucosal environment that render the FRT vulnerable to infectious diseases. The objective of this study was to identify genes in human endocervix tissues that were differentially expressed in the follicular versus the luteal phases of the menstrual cycle using gene expression profiling...

The use of assisted reproductive technologies (ART) has increased steadily. There has been a corresponding increase in the number of ART-related procedures such as hysterosalpingography (HSG), saline infusion sonography (SIS), hysteroscopy, laparoscopy, oocyte retrieval, and embryo transfer (ET). While performing these procedures, the abdomen, upper vagina, and endocervix are breached, leading to the possibility of seeding pelvic structures with microorganisms. Antibiotic prophylaxis is therefore important to prevent or treat any procedure-related infections...

Epithelioid trophoblastic tumor (ETT) is a rare gestational trophoblastic neoplasm of chorionic-type intermediate trophoblasts, and it is most frequently located in the lower uterine segment and endocervix. Due to the epithelial-growth pattern with geographic necrosis exhibited by the neoplastic cells, ETT is commonly confused, both clinically and pathologically, with squamous cell carcinoma. Although there have been no previous reports of ETT focusing on computed tomography (CT) or magnetic resonance imaging (MRI) findings, we report a case of uterine ETT with special attention to the MRI findings referring to the pathological findings and MR images of previous reports...

Uterine cervix cancer is the second most common malignancy in women worldwide with human papillomavirus (HPV) as the etiologic factor. The two main histological variants, squamous cell carcinomas (SCC) and adenocarcinomas (AC), resemble the cell morphology of exocervix and endocervix, respectively. Cancer metabolism is a cancer hallmark conditioned by the microenvironment. As uterine cervix homeostasis is dependent on lactate, we hypothesized lactate plays a role in uterine cervix cancer progression. Using in vitro (SiHa-SCC and HeLa-AC) and BALB-c/SCID models, we demonstrated that lactate metabolism is linked to histological types, with SCC predominantly consuming and AC producing lactate...

The combinatorial effects of genistein and estrogen (E) or estrogen plus progesterone (E+P) on CFTR, AC and cAMP levels in cervix were investigated. Ovariectomised adult female rats received 50 or 100mg/kg/day genistein with E or E followed by E+P [E+(E+P)] for seven consecutive days. Cervixes were harvested and analyzed for CFTR mRNA levels by Real-time PCR. Distribution of AC and CFTR proteins in endocervix were observed by immunohistochemistry. Levels of cAMP were measured by enzyme-immunoassay. Molecular docking predicted interaction between genistein and AC...

OBJECTIVE: Primary squamous cell carcinoma (SCC) of the ovary in humans is rare. Most cases represent a malignant transformation of ovarian teratoma, Brenner tumor, or endometriosis. The etiology of this cancer remains largely unknown. Human papillomavirus (HPV) infection is a critical factor that induces tumor formation, particularly cervical cancer. Therefore, this study aimed to evaluate the association of HPV with malignant transformation of mature cystic teratoma (MCT) into SCC of the ovary...

STUDY OBJECTIVE: To demonstrate a laparoscopic vaginal-assisted nerve-sparing radical trachelectomy. DESIGN: An edited educational video, including a step-by-step description of the procedure. SETTING: Radical trachelectomy is the main surgical indication for selected cases of initial cervical cancer with a fertility-sparing approach. Although transvaginal access is the most traditional route, this technique has not gained widespread acceptance because of the complexity of the ureteral dissection and the limited amount of resected parametrial tissue...

Perivascular epithelioid cell tumors (PEComas) most frequently involve the uterus, particularly the uterine corpus and very occasionally the cervix. One case of PEComa identified using a conventional cervical smear has previously been documented. Herein, we present the second such case. The patient was a 51-year-old woman with abnormal genital tract bleeding. Samples collected for conventional cervical smears were submitted for cytopathological examination, which revealed discohesive monotonous tumor cells showing epithelioid morphology, ample cytoplasm that was pale to weakly eosinophilic, and mildly enlarged nuclei...

BACKGROUND: Cervicitis is an inflammatory condition of the cervix associated with upper genital tract infection and reproductive complications. Although cervicitis can be caused by several known pathogens, the etiology frequently remains obscure. Here we investigate vaginal bacteria associated with bacterial vaginosis as potential causes of cervicitis. METHODS: Associations between vaginal bacteria and cervicitis were assessed in a retrospective case-control study of women attending a Seattle sexually transmitted disease clinic...
