OBJECTIVE: Recent studies have suggested that endometriosis could be the result of excessive activation of signal transducer and activator of transcription 3 (STAT3), which is associated with the regulation of essential cellular mechanisms …

Pneumoperitoneum usually presents as a surgical emergency, especially in patients with a history of trauma. However, we recently encountered an atypical case of pneumoperitoneum at a hysterectomy site following blunt trauma, indicating that…

Ehlers-Danlos syndrome (EDS) is a group of related connective tissue disorders consisting of 13 subtypes, each with its own unique phenotypic and genetic variation. The overlap of symptoms and multitude of EDS variations makes it difficult …

Kisspeptins, products of KISS1 gene, are ligands of the G-protein coupled receptor (GPR54), and the kisspeptin-GPR54 signaling has an important role as an upstream regulator of gonadotropin releasing hormone (GnRH) neurons. Interestingly, e…

Background: Cancer development after cholecystectomy remains debatable. We estimated the major cancer incidence rates after cholecystectomy stratified by age and sex. Methods: The records of 408,769 subjects aged >20 years were extracted fr…

Endoplasmic reticulum (ER) stress serves as a key modulator of the inflammatory response by controlling nuclear factor-kappaB (NF-κB) signaling. Previous studies from our laboratory have reported an abnormal induction of ER stress linked to…

Background: Several preclinical and clinical studies have suggested that BRCA-mutation carriers may have decreased ovarian reserve. However, data in this area are limited and inconsistent, especially in young breast cancer patients. Objecti…

Based on our preliminary results, we examined the possible role of low-dose and chronic-exposing of the chemicals those are known as endocrine disrupting chemical (EDC), on the proliferation of uterine endometrium and the localization of st…

ObjectiveThe aim of this study was to compare long-term use of combined oral contraceptive (COC) after gonadotropin-releasing hormone (GnRH) agonist plus add-back therapy with dienogest (DNG) treatment as medical treatments after surgery fo…

Dienogest, a specific progesterone receptor agonist, is used in the treatment of endometriosis. However, it is still unclear as to the mechanisms of therapeutic effects on endometriosis. Our recent study showed that endometriosis may be the…

Endoplasmic reticulum (ER) stress is known to reduce invasiveness in some cancer cells by inhibiting the AKT/mTOR pathway. A previous study from our laboratory suggested that ER stress is promoted by progesterone in human endometrial cells,…

This study assessed the functional role of WNT genes and the association between WNT signalling cascades and fibrosis in interstitial cystitis/bladder pain syndrome (IC/BPS) patients. Twenty-five patients (3 males, 22 females; mean age 59.7…

ObjectiveThis study was conducted to evaluate the effects of long-term postoperative dienogest (DNG) use for the treatment of endometriosis on bone mineral density (BMD).Study designSixty reproductive-aged women who underwent conservative s…

In some human cancer cells, PTEN (phosphatase and tensin homolog deleted on chromosome 10) is known to regulate autophagy induction positively through the inhibition of PI3K/AKT pathway, leading to the activation of mTOR, a major negative r…

PurposeThis study was performed to compare the efficacy and tolerability of GnRH agonist with add-back therapy versus dienogest treatment for preventing pelvic pain recurrence after laparoscopic surgery for endometriosis.MethodsSixty-four r…

ObjectiveAs endometrioma frequently recurs after conservative surgery, long-term postoperative medical treatment for the prevention of recurrence is necessary. However, it has not been elucidated whether long-term postoperative medical trea…

Study objectiveYoung age is a possible risk factor of endometriosis recurrence after surgery. However, the efficacy of postoperative medical treatment has not been well addressed in adolescents. The purpose of this study was to evaluate whe…

ObjectiveTo elucidate the therapeutic mechanisms of progestin and the effects of progesterone and progestin (dienogest) on autophagy induction and regulation in endometriotic cells, specifically the effects of progesterone and dienogest on …

Concerns for negative effects of oral contraceptives (OCs) on bone mineral density (BMD) in long-term users have been raised, since OCs suppress the hypothalamic-pituitary-ovarian axis. However, there have been still limited data regarding …

Study objectiveTo evaluate the clinical characteristics of endometrioma in adolescent women compared to women of other age groups.DesignCross-sectional study.SettingA university hospital.ParticipantsThree-hundred seventy-six women.Intervent…

Mammalian target of rapamycin (mTOR) is known to be a major negative regulator of autophagy. Recent studies have shown that mTOR activity is abnormally increased in endometriotic lesions. In endometriosis, abnormal mTOR activity may contrib…

We evaluated the laterality of primary endometrioma and characteristics of patients according to the laterality of recurrent endometrioma in 140 women with recurrent endometrioma after conservative surgery. Histologically confirmed recurren…

PurposeThe purpose of this study is to evaluate the "mushroom cap" sign on T2-weighted MR imaging in patients with submucosal tumors in the rectosigmoid colon.MethodsFrom January 2001 to August 2009, 12 patients with four different diseases…

A few studies have investigated the effects of laparoscopic cystectomy for endometrioma on ovarian reserve using serum anti-Müllerian hormone (AMH) levels and have shown inconsistent results. This prospective study was performed to estimate…
