Primary female genital system lymphoma complicated by a recurrent mucinous borderline ovarian tumor: a case report and review of the literature

Background Primary female genital system lymphoma (PFGSL) is an infrequent entity. All genital organs may be affected, and most PFGSLs are localized to the cervix, uterine body, and ovaries. The clinical manifestations are nonspecific, which complicates a timely diagnosis. We report an unexpected case of PFGSL and discuss the disease characteristics by reviewing the literature. Case presentation A 48-year-old G3/P2 woman presented to the Department of Gynecology with a physical examination. Ultrasound examination and CT revealed pelvic masses. The woman underwent surgical treatment because of the pelvic masses and underwent a hysterectomy for a recurrent mucinous borderline ovarian tumor. However, the results of the postoperative pathological examination showed diffuse large B-cell lymphoma of the endometrium. After four courses of chemotherapy, the woman was in good condition. The clinical manifestations were nonspecific, which made a timely diagnosis complex. Conclusion This case highlights the importance of the difficulty in detecting early PFGSL early and how easily nonspecific manifestations can be ignored. It may lead to missing the best time for early treatment.

PROBLEMATIC ISSUES IN THE ETIOLOGY AND PATHOGENESIS OF ADENOMYOSIS

Nowadays, adenomyosis represents one of the most common pathology of female genital system. It occurs at different ages, including nulliparous, infertile and multiparous women. The etiology of adenomyosis is still under investigation. Despite the fact that there are many different theories, none of them fully explain the mechanisms of adenomyoisis development. The pathogeneis of adenomyosis is also less studied. Many studies indicate the involvement of female sex hormone receptors, cell proliferation and apoptosis, as well as the involvement of inflammation. Some investigators describe the malignant transformation of adenomyosis, which makes the study of the disease etiology and pathogenesis more important. In current review, we discuss the different theories of adenomyosis development, as well as the risk of malignant transformation.

Detection of severe acute respiratory syndrome corona virus 2 in cervico-vaginal secretion of COVID-19-affected female: A prospective observational study from India

Background: The novel severe acute respiratory syndrome corona virus 2 (also known as 2019-nCoV) is a highly infectious agent and is declared as a global public health emergency by the World Health Organisation. The main known transmission route of severe acute respiratory syndrome corona virus 2 is through respiratory air droplets. Although recent studies have revealed that the virus is detectable in the throat, blood, urine, anal swabs, tears and even faeces; however, modes of transmission other than respiratory droplets has not been studied much. Knowledge on the presence of the virus in the female genital tract may help determine the risk of sexual transmission as well as the risk of mother-to-child transmission. However, not much data are available yet regarding the presence of the virus in the female genital system. Hence, to explore the presence of the virus in the female genital system and possibility of sexual transmission, a study was conducted where in we tried to detect severe acute respiratory syndrome corona virus 2 in cervico-vaginal secretions. Methods: From July 2020 to September 2020, 35 COVID-19-positive female patients admitted to tertiary care teaching institute of Eastern India, which is now declared dedicated Corona Hospital and Centre of Excellence for COVID-19 care, who consented for the research were enrolled in this prospective observational study. Proper gynaecological history, clinical records along with laboratory findings of the patient was recorded. The possibility of the sexual transmission of the virus from female to her male partner was to be ascertained by testing the presence of severe acute respiratory syndrome corona virus 2 in the vaginal, cervical secretions by reverse transcriptase polymerase chain reaction. Results: All 35 COVID-19-positive female patients were tested for severe acute respiratory syndrome corona virus 2 in their vaginal and cervical secretions by reverse transcriptase polymerase chain reaction. All the samples were tested negative for the virus. Conclusion: Findings from this study reveals that severe acute respiratory syndrome corona virus 2 is not present in the cervical and vaginal secretions, and the possibility of transmission from female to her male partner by vaginal sexual intercourse is unlikely.

Morphological and molecular characterization of Aporcella femina sp. n. (Dorylaimida, Aporcelaimidae) from Nigeria

A new species of the genus Aporcella collected from a watermelon field in Nigeria is described, including its morphological and molecular (small subunit (SSU) and large subunit (LSU) ribosomal DNA (rDNA)) characterization. Aporcella femina sp. n. is distinguished by its 3.21–3.64 mm-long body, inner cuticle layer with fine but distinct transverse striation, lip region offset by deep constriction, 22–25 μm broad, odontostyle 20–26 μm, neck 661–811 μm long, pharyngeal expansion occupying 52–56% of the total neck length, female genital system didelphic–amphidelphic, uterus 191–350 μm or 1.9–3.3 mid-body diameters long, V = 52–57, tail short and convex conoid (35–48 μm, c = 72–98, c′ = 0.7–0.9) and males absent. Phylogenetic analyses based on the partial sequence of SSU and LSU (D2–D3) rDNA revealed a close relationship of A. femina sp. n. with other Aporcella species, confirming the monophyly of the genus as well as its association to a clade made of several taxa characterized by the absence of pars refringens vaginae.

Effect of oral administration of Rasnadi Ksheera and local Guduchyadi Kwatha Parisheka in Udavartini Yonivyapad W.S. R. to Primary dysmenorrhoea

The diseases related to female genital system are elaborated under umbrella of ‘Yonivyapad’ in Ayurveda. Vitiated Vatadosha causes pain during menstruation and subsides after menstruation. This condition is explained as Udavartini Yonivyapad in Charaka Samhita. Both Primary dysmenorrhea as per modern gynaecology and Udavartini Yonivyapad from Ayurveda show similarities in their signs and symptoms, especially pain during menstruation. After deliberation of Charaka Samhita, effect of oral administration of Rasnadi Ksheera and local Guduchyadi Kwatha Parisheka were considered for their textual reference on ‘Yonishoola’. For this single arm, open labelled, prospective study; 30 married females between the age of 18 to 42 years with Pratyatma Lakshana (cardinal features) of Udavartini Yonivyapad & signs and symptoms of primary dysmenorrhea were selected. They were given Rasnadi Ksheera 80 ml orally in Apana Kala (i.e. Before lunch & dinner) for two months. Guduchyadi Kwatha Parisheka (Vaginal Douche) was performed in Rutukala for 8 days duration (i.e. from 5th day of menstrual cycle to 12th day of menstrual cycle) for two consecutive cycles. The assessment was done on basis of standard parameters before treatment and after treatment. The subjective parameters such as Spasmodic pain in abdomen, Lumbo-sacral backache, Pain radiating to thigh, Vomiting, Constipation were assessed. The study data generated and collected was put to statistical analysis to reach to the final results and conclusions. It was concluded that oral administration of Rasnadi Ksheera and local Guduchyadi Kwatha Parisheka were highly effective in symptomatic management of Udavarta Yonivyapad W. S. R. to primary dysmenorrhea.
