Stem cells may open new horizons in various gynecological disorders
In-Sun Hong, PhD, a researcher in regenerative medicine at Korean Gachon University has published a comprehensive review on the role of stem cells in gynecological disorders in a recent issue of the International Journal of Biological Sciences. Endometrium changes the menstrual cycle and the extraordinary regenerative capacity depends on tissue-resident stem cells within the uterine mucosa. Despite variations in specific characteristics among endometrial stem cells, the common denominator is strong self-renewal capacity and the ability to differentiate into multiple cell types. The…

Hot research in endometriosis; new vessel formation: angiogenesis
Caixia Bo and Yunfei Wang from Jining Medical University, China have recently published their comprehensive review on angiogenesis-related aspects of endometriotic tissues in a recent issue of journal named Molecular Medicine Reports. The main potential pathogenetic aspects of endometriosis include retrograde menstruation, uterine stem cells, and somatic epithelia. Whichever theory is operative, ectopic endometria needs nutrient support via new vessel formations, i.e., angiogenesis is the key factor for the viability of these ectopic islands. The authors have made literature search for…

Inguinal endometriosis is a commonly neglected differential diagnosis
A case series of inguinal endometriosis with eight patients from Tehran, Iran has appeared in a recent issue of the Journal of Medical Case Reports. It is a fact that many inguinal endometriosis cases are undiagnosed since they undergo herniorrhaphy by surgeons without any consideration for endometriosis. The estimated incidence of inguinal involvement is about 0.3–0.6% in all endometriosis cases and the total number of reported cases is 133 till 2022. This report presents eight Iranian cases of inguinal endometriosis…

Chronic stress may be involved both in the pathogenesis and progression of endometriosis
Chong Lu and associates from Shangai, China have published their novel research on chronic stress and endometriosis in a recent issue of International Journal of Molecular Sciences. During the natural course of endometriosis many patients are under chronic stress, which may yield depression, anxiety, and low social support, however, there is also an intriguing dilemma whether chronic stressful environment could cause endometriosis too. Patients confirmed as having endometriosis via intraoperative pathology consultations were recruited from the Fudan University Affiliated Obstetrics…

Hands-on proposals for medical counseling and verbalizations to use for women with endometriosis
An overview has been published recently in the Archives of Gynecology and Obstetrics on patient–doctor communication and psychological counseling in endometriosis by two academicians, Drs. Wischmann and Ditzen, from Heidelberg University, Germany. There is no known cure for endometriosis and primary management aims at controlling and ameliorating the symptoms. Since the stressful chronicity of endometriosis, the patients may feel passive/dependent and helpless during the natural course of the ailment. Interventions aimed primarily at women with traumas may also be helpful in the…

Clinical awareness for endometriosis in infertility should be surged
A team of researchers from multiple centers including Stanford University and Swiss Federal Laboratories, led by Dr.Camran Nezhat have published their cross-sectional retrospective study on endometriosis and unexplained infertility association. This research paper appeared in a recent issue of the Journal of Clinical Medicine. It is a pity that potential stigma and healthcare access problems may hamper the diagnosis of endometriosis for about 11 years. Endometriosis patients face the physical and emotional burdens of the ailment, including chronic pain, dysmenorrhea, dyspareunia,…

Endometriosis vs. adenomyosis : is there a common pathogenesis ?
This is a collaborative review on the pathophysiology of adenomyosis and endometriosis by academicians of the University of Leicester, UK; Fudan University, Shanghai, China and Sapienza University of Rome, Italy, published in a recent issue of “Biomolecules”. The pathophysiology of endometriosis and adenomyosis remain still unresolved but a critical analysis of our current understanding is crucial. The so-called “endometrial determinism” theory is based on the hypothesis of abnormal endometrium as a predisposing factor for endometriosis whereas the tissue injury and…

Could brain-derived neurotrophic factor (BDNF) be a potential marker of endometriosis ?
Medical student Kyana Jafarabady and academicians from several medical centers in Iran have published their database research on Brain-derived neurotrophic factor (BDNF) in endometriosis patients in a recent issue of BMC Women’s Health. BDNF is a neurotrophin that plays an important role in the development, survival, and plasticity of neurons of the central nervous system. However scientific research suggests that it is also expressed in peripheral tissues, including the reproductive system. High levels of BDNF have been reported in the peritoneal fluid,…

New visions on diaphragmatic endometriosis
Elvin Piriyev and Thomas Römer from Academic Hospital Cologne Weyertal, Germany have published their retrospective analysis of diaphragm endometriosis in a recent issue of the European Journal of Obstetrics and Gynecology. About 7-10% of reproductive-age women have endometriosis but diaphragm involvement is estimated to be around 1.1 % among these patients. Diaphragm endometriosis frequently accompanies pelvic endometriosis and may either be symptomatic or asymptomatic. The authors aimed to investigate and present the clinical characteristics of diaphragm involvement, and to reveal whether…

Beware of deep endometriosis involving ureter
Dr. Vacaroiu and colleagues from the Romanian academic milieu have published a case report of urinary tract endometriosis that could have otherwise resulted in kidney failure when remained undiagnosed. This case appeared in a recent issue of the Journal of Clinical Medicine. Extrapelvic endometriotic lesions are more commonly revealed in the 4th decade and are generally diagnosed about 5 years later than genital lesions. Less than 1% of endometriosis occurs in the urinary tract, often due to its subclinical progression. hydronephrosis…

A unique approach for visualising endometriosis during surgery
Dr. Jing Peng and associates from Shangai, China have made an experimental study on precise visualization of endometriotic lesions with gonadotropin-releasing hormone analog-modified indocyanine green, publishing their results in the Journal of Molecular Imaging. Surgical interventions are important aspects of endometriosis and precise intraoperative specification and excision of lesions are critical. Imaging substances are of utmost importance in this regard and methylene blue, 5-Aminolevulinic acid (5- ALA), and several others have been proposed during intraoperative visualization for endometriosis. Indocyanine green…

A herbal product has promising results in experimental endometriosis
Neroli oil (bitter orange) is a nontoxic volatile substance from the flowers of Citrus aurantium that belongs to the Rutaceae family. This oil has notable anti-inflammatory effects besides potent antioxidant activity with 100% singlet oxygen scavenging activity. Contemporary pathophysiological views on endometriosis emphasize inflammatory etiology besides oxidative stress as the initiators and perpetuators of this notorious disease. Proinflammatory cytokines take major roles and progression of endometriotic lesions while vascularization has a crucial effect. Dr. Mujde Canday and colleagues from Kars Kafkas…

Quantification of nerve bundle density as a biomarker for endometriosis utilizing PGP9.5 immunostaining
Scientists from Netherlands and Canada have published their authentic study on immunohistochemically assessed nerve fiber bundles of endometriotic tissues in a recent issue of Frontiers in Reproductive Health. Endometriotic tissues have nerve fibers which are stimulated in inflammatory processes leading to increased physical stimuli. In this context, local neuroproliferation or "neurogenesis" may have a role, as quantitative increase in nerve fibers around endometriotic tissues are shown. However, pelvic pain symptoms are quite different among endometriosis patients so that revised American Society…
