A Rare Case of the Cervical Endometriosis and Overview of the Literature.

Cervical endometriosis is an uncommon form of endometriosis that is frequently diagnosed incidentally during histopathological evaluation of a hysterectomy or cervical biopsy specimens. Although some cases may be asymptomatic, the symptoms in some patients range from life-threatening hemorrhage to severe chronic pelvic pain. In asymptomatic patients, no further intervention might be required apart from observation and follow-up; however, patients with significant symptoms will require surgery. Primary cervical endometriosis is defined as presence of endometrial tissue on the anterior lip of the cervix, limited to the cervix surface and not extending below the squamous epithelium. Secondary cervical endometriosis is more common than the primary type and describes the disease extensions from the pelvis, or usually the rectovaginal septum. Superficial endometriosis is usually diagnosed by fine-needle aspiration, colposcopy, and cervical biopsy after a routine cervical smear, as endometrial cells detected during a PAP smear may be mistakenly removed as atypical glandular cells. Deep endometriosis may cause pelvic pain, vaginal bleeding, and spotting. In this case report, we present a rare case of cervical endometriosis, characterized by pelvic pain and menstrual irregularity, with endometrioma and adenomyosis, confirmed by histopathological evaluation of the specimen. A summary of the cervical endometriosis cases overview has been made to describe the changing clinical landscape of this rare condition.

The Use of Thiol/Disulfide as a Novel Marker in Premature Ovarian Failure.

The study aimed to compare the dynamic thiol/disulfide homeostasis between patients with premature ovarian failure (POF) and healthy women. A total of 77 women, 40 POF and 37 healthy controls, were recruited from a university hospital between December 2013 and June 2015. Blood samples were taken from patients to evaluate follicle stimulating hormone (FSH), luteinizing hormone, estradiol and thiol/disulfide levels. A new, fully automated method was used to measure plasma thiol, total thiol and disulfide levels. Disulfide levels, disulfide/native thiol and disulfide/total thiol ratios were significantly increased, native thiol/total thiol levels were significantly decreased in POF patients compared to controls (p < 0.001). FSH was negatively correlated with native thiol and native thiol/total thiol levels and positively with disulfide, disulfide/native thiol, and disulfide/total thiol levels. This is the first study demonstrating the thiol/disulfide homeostasis in women with POF and may help us understanding the pathophysiology.
