New models to study vulvodynia: hyperinnervation and nociceptor sensitization in the female genital tract

Vulvodynia is a prevalent form of chronic pain, most com- monly affecting the vaginal vestibule （vestibulodynia） （Pukall et al., 2016）. Women with vulvodynia describe intense pain in response to light touch of the affected region, such that sexual function and other activities can be severely limited. Medical costs associated with vulvodynia are high, exceeding $21 billion annually in the United States （Xie et al., 2012）. The high level of direct medical costs has been linked to high treatment failure rates. Many women with the disorder consult multiple practitioners and undergo multiple courses of treatment with limited benefit.

HUMAN PAPILLOMAVIRUS IN CONDYLOMA ACCUMINATA AND OTHER BENIGN LESIONS OF THE FEMALE GENITAL TRACT

PCR was used to detect (HPV) in condyloma accuminata (CA),pseudocondyloma whose cause is unclear,and the other benign lesions in female genital tract.The results showed that HPV prevalence rate in CA was 98.2%,type 6 was in 11 was 85.7%,

Extramammary Paget’s Disease Manifested by Intraepithelial Adenocarcinoma of the Vulva and Anus Combined with Invasive Adenocarcinoma of the Ampullary Part of the Rectum

The Object of the Study: The author of the given paper describes an unusual combination of two diseases: extramammary Paget’s disease manifested by intraepithelial adenocarcinoma of the vulva and anus combined with invasive adenocarcinoma of the ampullary part of the rectum and describes the atypical manifestations of these diseases. The Content: The content of this research paper includes a description of the patient, an analysis of the clinical picture, diagnostic methods and therapeutic interventions used, a report of the following disease, and the result of the presented case. The Result of the Research Work: The result of the research work is the analysis of a clinical case with two different tumors, where such a combination of tumors is rarely described in the literature. Moreover, no large specific sample with this combination of diseases is available. Patient Characteristics: The given case report describes a patient of the Palliative Care Unit of the Gerontology Clinic with a primary diagnosis of C20-rectal adenocarcinoma in the background of the anal canal, perineal skin Paget’s disease, stage IV. The presented complications of the patient’s primary diagnosis are multiple metastases in the liver;status post palliative chemotherapy;hepatomegaly;metastases to abdominal lymph nodes, inguinal lymph nodes;metastases at Th12, L4 level;pain syndrome. The presented above combination of diagnosed diseases is very rare. Applied Diagnostics: In October 2021, it was performed diagnostic manipulation: biopsy and the pathologist have provided a microscopic description. The first tissue fragment had a pronounced electrothermal lesion and the epithelial structures were not valuable. The second skin tissue fragment was covered with hyperplastic and acanthotic epithelium;its basal and middle layers contained multiple large cells proliferates extending into the medial epidermis, and the cytoplasm of these cells reacted positively with PAS (Periodic Acid Schiff reaction). It needs to be noted that the patient had previously had several years of biopsies from the perineal and anal epidermis, where Paget’s disease had also been diagnosed. The performed immunohistochemistry showed these cells to be CK20 positive, CK7 rare positive and p16 negative. The following pathohistological findings were made: morphological and immunohistochemical picture is consistent with Paget’s disease. According to the ICD-10, the patient was diagnosed with C51 malignant neoplasm of the female external genitalia. Using imaging diagnostics, it became clear that the patient’s rectal adenocarcinoma had progressed to metastatic stage with distant liver metastases in the background of anal canal, perineal skin Paget’s disease. Therapeutic Plan of the Patient: Based on the patient’s main diagnoses, the complications of the principal diagnosis, the patient’s overall severe condition, pain syndrome, age and comorbidities, palliative chemotherapy was approved as a therapeutic option in council of doctors. Monitoring and Outcome of the Patient: The patient’s general condition was becoming worse over time, and she was diagnosed with exitus latalis in December 2022. At that time, the patient was discharged from hospital and was on palliative care at home under the control of her family physician.

The Right Decision on the Vaginal Construction in Mayer- Rokitansky-Kiister-Hauser syndrome

Vaginal agenesis is a congenital anomaly that affects the life of one of each four thousand women around the world. There is a trend that patients request immediate surgical correction, instead of passive vaginal dilatation. Therefore a differentiated counselling should be provided. We present a comparative chart, based on published evidence, with aspect to the available techniques, which will facilitate the decision- making process in the clinical practice. From our point of view, the best results are achieved with techniques that combine the advantages of the minimal-invasive surgery with those derived of the use of peritoneum as coveting tissue of the neovagina. Nevertheless there is a lack on interdisciplinary consensus about the best option to restore the physical and sexual quality of life.

Functional Studies of Castor(Ricinus communis L.)PLC Family Genes in Arabidopsis Inflorescence Development

Castor(Ricinus communis L.)is one of the top 10 oil crops in the world,and inflorescence is a trait that directly affects its yield.Phospholipase C(PLCs)is involved in many plant activities and metabolic processes.To study the functions of PLC family genes in the regulation of the inflorescence development of the female line of Lm-type castor aLmAB2,we determined the expression levels of six PLC family genes of three types of inflorescences of aLmAB2(isofemale line,female line,bisexual line)at different developmental stages.The results showed that the 6 genes of the castor PLC family had relative expression levels at different developmental stages of the three types of inflorescences.The subcellular location of all six protein products was the cell membrane.The six genes were heterologously overexpressed in Arabidopsis thaliana to obtain the T3 generation-resistant Arabidopsis thaliana plants.The results showed that the overexpression of six genes significantly promoted the maturation of Arabidopsis thaliana,the growth of lateral moss,and the development of flowers and pods,but the development of basal leaves and stem leaves of Arabidopsis thaliana was significantly inhibited.According to homology analysis,it is speculated that PLC2,PLC2M,PLC2N,PLC4,PLC4X2,and PLC6 genes have the same regulatory function.
