RESUMEN
Adenomyosis (AM) is a common gynecological disorder characterized by the presence of endometrial glands and stroma within the uterine myometrium. It is associated with abnormal uterine bleeding (AUB), dysmenorrhea, and infertility. Although several mechanisms have been proposed to elucidate AM, the exact cause and development of the condition remain unclear. Recent studies have highlighted the significance of macrophage polarization in the microenvironment, which plays a crucial role in AM initiation and progression. However, a comprehensive review regarding the role and regulatory mechanism of macrophage polarization in AM is currently lacking. Therefore, this review aims to summarize the phenotype and function of macrophage polarization and the phenomenon of the polarization of adenomyosis-associated macrophages (AAMs). It also elaborates on the role and regulatory mechanism of AAM polarization in invasion/migration, fibrosis, angiogenesis, dysmenorrhea, and infertility. Furthermore, this review explores the underlying molecular mechanisms of AAM polarization and suggests future research directions. In conclusion, this review provides a new perspective on understanding the pathogenesis of AM and provides a theoretical foundation for developing targeted drugs through the regulation of AAM polarization.

An accessory and cavitated uterine mass (ACUM) is a rare anomaly with an embryological origin of dysfunctionning female gubernaculum. It is an accessory mass internally lined with normal endometrium, separated from the uterine cavity and located near the insertion of the round ligament. ACUM's clinical manifestations are severe dysmenorrhea and/or chronic pelvic pain. It is a relatively unknown condition, which makes its diagnosis complicated and suggests a large differential diagnosis. We report the case of a 31-year-old female presenting with pelvic chronic pain and crippling dysmenorrhea. The initial work-up consists of a magnetic resonance imaging showing an interstitial lesion possibly corresponding to an ACUM. This supposition was then confirmed by histopathology.
La masse utérine cavitaire accessoire (MUCA) est une anomalie rare dont l'origine est embryologique et serait liée à un dysfonctionnement du gubernaculum féminin. Il s'agit d'une masse accessoire non communicante située à proximité de l'insertion du ligament rond, tapissée par un endomètre normal. La MUCA se manifeste par une dysménorrhée sévère et/ou des douleurs pelviennes chroniques. Il s'agit d'une pathologie relativement méconnue, ce qui rend son diagnostic difficile, et qui suggère un large diagnostic différentiel. Nous rapportons ici le cas d'une femme de 31 ans présentant des douleurs pelviennes chroniques et une dysménorrhée invalidante. La mise au point initiale par résonance magnétique pelvienne a montré la présence d'une lésion interstitielle pouvant correspondre à une MUCA, qui a ensuite été confirmée à l'examen histopathologique.

Dysmenorrhea is a prevalent gynecological disease among women at reproductive age. It is classified as the primary dysmenorrhea and the secondary dysmenorrhea according to the etiology. The primary dysmenorrhea is caused by uterine hypercontraction without any identifiable pelvic lesions, while the secondary dysmenorrhea is incurred by gynecological disorder with pelvic organic lesions. However, the underlying mechanism of dysmenorrhea is not completely clear. Animal models of dysmenorrhea, especially mouse and rat model, are helpful to explore the pathophysiological mechanism of dysmenorrhea, clarify the therapeutic effect of compounds, and guide clinical treatment. The murine model of primary dysmenorrhea is commonly induced by oxytocin or prostaglandin F2α, while the secondary dysmenorrhea murine model was further created by injecting oxytocin on the basis of the established primary disease model. This review summarizes the current progress of dysmenorrhea models in rodent, including experimental methods, corresponding evaluation indexes, and the advantages and disadvantages of various murine dysmenorrhea models, in order to provide a reference for the selection of murine dysmenorrhea models and the further study of the pathophysiological mechanism of dysmenorrhea.

BACKGROUND: Rbert's uterus, also known as asymmetric septate uterus, is a rare genital malformation first reported by Dr. Robert in 1970. Robert's uterus is characterized by a septate uterus with a blind hemicavity and an intact external fundus. According to some reports, Robert's uterus was typically managed by laparoscopic uterine resection of a hemicavity, laparoscopic endometrectomy, and even hysterectomy. Considering that fertility preservation is important in young patients, we recommend ultrasound-guided hysteroscopic septum resection as an optimum treatment for Robert's uterus. CASE PRESENTATION: Herein is described a clinical case of Robert's uterus in a 15-year-old girl who was misdiagnosed for primary dysmenorrhea in the beginning. Magnetic resonance imaging (MRI) and 3-dimensional (3D) ultrasound identified an asymmetrical uterine septum. The patient was treated using ultrasound-guided hysteroscopic treatment without laparoscopy. The surgical procedure lasted less than an hour, and the symptoms of dysmenorrhea were relieved during a six months follow-up. CONCLUSIONS: Ultrasound-guided hysteroscopic septum resection is the preferred treatment for Robert's uterus.

BACKGROUND: Primary dysmenorrhea (PDM) is highly associated with mood symptoms. However, the neuropathology of these comorbidities is unclear. In the present study, we aimed to investigate the structural changes in the amygdala of patients with PDM during the pain-free phase using a surface-based shape analysis. METHODS: Forty-three PDM patients and forty healthy controls were recruited in the study, and all participants underwent structural magnetic resonance imaging scans during their periovulatory phase. FMRIB's Integrated Registration and Segmentation Tool (FIRST) was employed to assess the subcortical volumetric and surface alterations in patients with PDM. Moreover, correlation and mediation analyses were used to detect the clinical significance of the subcortical morphometry alteration. RESULTS: PDM patients showed hypertrophic alteration of the amygdala in the left superficial nuclei and right basolateral and superficial nuclei but not for the whole amygdala volume. The hypertrophic amygdala was associated with disease duration, pain severity and anxiety symptoms during the menstrual period. Furthermore, the hypertrophic left amygdala could mediate the association between disease duration and anxiety severity. CONCLUSIONS: The results of the current study demonstrated that the localized amygdala shape hypertrophy was present in PDM patients even in the pain-free phase. In addition, the mediator role of the hypertrophic amygdala indicates the potential target of amygdala for anxiety treatment in PDM treatment in the pain-free phase.

PURPOSE: To summarize the clinical characteristics and surgical option of Robert's uterus. METHODS: We reported a rare case of Robert's uterus with severe uterine adhesion with successive laparoscopic and hysteroscopic surgery. To our knowledge, such a case has not been reported previously. We also performed a systematic literature review from the PubMed, Embase, and Cochrane databases. RESULTS: Our patient with Robert's uterus with severe uterine adhesions was successfully treated with hysteroscopic septal resection and hysteroscopic adhesiolysis, and the intractable dysmenorrhea disappeared after the hysteroscopic septal resection. In our study, we analyzed the selected 22 reported cases, 10/22 cases (45.5%) were diagnosed before age 20; 20/22 cases (90.91%) experienced dysmenorrhea, 19/22 cases (86.36%) were with hematometra. 5/22 cases (22.73%) underwent re-operation or a third surgery before diagnosis and management. CONCLUSION: Robert's uterus, a rare congenital abnormality of Mullerian duct development, consists of an oblique septum and non-communicating asymmetrical uterine hemi-cavity. The main symptoms are the presence of hematometra and severe dysmenorrhea. Septal resection is the main surgical procedure; however, the rarity and difficulty obtaining a pre-operative diagnosis lead to a high rate of misdiagnosis and second surgery.

ETHNOPHARMACOLOGICAL RELEVANCE: The species Lippia origanoides Kunth, popularly known as "salva-de-marajó", is used in Brazilian traditional "quilombola" communities to treat menstrual cramps and uterine inflammation. AIM OF THE STUDY: Evaluate the spasmolytic activity of Lippia origanoides essential oil (LOO) on experimental models of uterine conditions related to menstrual cramps and investigate its mechanism of action. MATERIALS AND METHODS: Virgin rat-isolated uterus was mounted in the organ bath apparatus to evaluate the spasmolytic effect of LOO on basal tonus and contractions induced by carbachol, KCl, or oxytocin. We used pharmacological agents to verify the relaxation mechanism of LOO. The evaluation of uterine contractility in virgin rats, after treatment with LOO for three consecutive days, was carried out by the construction of a concentration-response curve with oxytocin or carbachol. The primary dysmenorrhea animal model was replicated with an injection of estradiol cypionate in female mice for three consecutive days, followed by intraperitoneal application of oxytocin. RESULTS: LOO relaxed the rat uterus precontracted with 10-2 IU/mL oxytocin (logEC50 = 1.98 ± 0.07), 1 µM carbachol (logEC50 = 1.42 ± 0.07) or 60 mM KCl (logEC50 = 1.53 ± 0.05). It was also able relax uterus on spontaneous contractions (logEC50 = 0.41 ± 0.05). Preincubation with glibenclamide, propranolol, phentolamine or L-NAME in contractions induced by carbachol did not alter significantly the relaxing effect of LOO. However, in the presence of 4-aminopyridine, CsCl or tetraethylammonium there was a reduction of LOO potency, whereas the blockers methylene blue, ODQ, aminophylline and heparin potentiated the LOO relaxing effect. Preincubation with LOO in a Ca2+ free medium at concentrations of 27 µg/mL or 81 µg/mL reduced the contraction induced by carbachol. The administration of LOO for 3 days did not alter uterus contractility. The treatment with LOO at 30 or 100 mg/kg intraperitoneally, or 100 mg/kg orally, inhibited writhing in female mice. The association of LOO at 10 mg/kg with nifedipine or mefenamic acid potentiated writhing inhibition in mice. CONCLUSIONS: The essential oil of L. origanoides has tocolytic activity in rat isolated uterus pre-contracted with KCl, oxytocin, or carbachol. This effect is possibly related to the opening of potassium channels (Kir, KV, and KCa), cAMP increase, and diminution of intracellular Ca2+. This relaxant effect, probably, contributed to reduce the number of writhings in an animal model of dysmenorrhea being potentiated by nifedipine or mefenamic acid. Taken together, the results here presented indicate that this species has a pharmacological potential for the treatment of primary dysmenorrhea, supporting its use in folk medicine.

Abstract Dysmenorrhea is a common condition among females that is characterized by painful cramps before or during menstruation. It is considered as a common gynecological complaint that affects the quality of women's life. The study evaluated prevalence of dysmenorrhea, its impact, associated risk factors, and the management strategies adopted by female university students in Taif city, Saudi Arabia. A cross-sectional study was conducted among 562 female students aged 18-30 years at the university level. The results showed a high prevalence rate of dysmenorrhea (79.4%) among the students. The most common risk factors were family history (87.4%) and length of menstruation (79%). Half (50.2%) of the respondents were absent at the university at least 1 day every month. The most widely used medications by the respondents were ibuprofen (42%) and paracetamol (40%), whereas only 3% used mefenamic acid, despite that they experienced complete pain relief with mefenamic acid. High prevalence rate of dysmenorrhea associated with risk factors such as family history and length of menstruation, was found among university students. However, pain and associated symptoms affect the quality of life.

Adenomyosis is associated with dysmenorrhea, infertility, and lesional fibrosis. The pathogenesis of adenomyosis is still unclear. Plasminogen activator inhibitor 1 (PAI-1) plays important roles in pathological activities like tumor metastasis and endometriosis. Our objective was to investigate the expression and localization of PAI-1 in eutopic and ectopic endometrium with adenomyosis and in endometrium without adenomyosis. We also sought to determine the relationship between PAI-1 immunoreactivity and the severity of dysmenorrhea and the extent of lesional fibrosis in adenomyosis. PAI-1 expression was significantly higher in the ectopic endometrium of patients with adenomyosis than in both the eutopic endometrium of patients with adenomyosis and the endometrium of controls. Ectopic PAI-1 expression correlated positively with dysmenorrhea visual analog scale (VAS) scores and the extent of lesional fibrosis in adenomyosis. High PAI-1 expression increased the likelihood of moderate to severe dysmenorrhea in adenomyosis. These results suggest that PAI-1 is involved in the adenomyosis-associated dysmenorrhea and lesional fibrosis, which provide a potential target in treating symptomatic adenomyosis.

RESEARCH QUESTION: Does connective tissue growth factor (CTGF) expression relate to adenomyotic fibrosis and determine the correlation between fibrosis with adenomyosis-associated dysmenorrhoea? DESIGN: Protein and mRNA expression of CTGF was detected by Western blots and real-time quantitative polymerase chain reaction in the endometrium of the control group and the eutopic and ectopic endometrium of the adenomyosis group. Collagen fibres and type I collagen in the myometrium were detected by immunohistochemistry and Masson's trichrome staining, and the correlations of CTGF protein and mRNA levels with the degree of fibrosis were analysed. Furthermore, the relationship between the severity of dysmenorrhoea and the degree of fibrosis was determined, and the correlation between uterus size and the degree of fibrosis was also analysed. RESULTS: Levels of CTGF mRNA and protein were significantly higher in patients with adenomyosis than in controls, and CTGF mRNA and protein expression in adenomyosis was positively correlated with fibrosis severity (râ¯=â¯0.57, P < 0.001 and râ¯=â¯0.39, Pâ¯=â¯0.012), which correlated positively with dysmenorrhoea and uterus size (râ¯=â¯0.42 and râ¯=â¯0.6, P < 0.002). CONCLUSIONS: Increased CTGF may contribute to the occurrence and fibrogenic progression of adenomyosis and may play an important role in dysmenorrhoea. The present study may provide ideas for treating adenomyosis-associated dysmenorrhoea.

OBJECTIVE: The objective of this video is to demonstrate different clinical presentations of peritoneal defects (peritoneal retraction pockets) and their anatomic relationships with the pelvic innervation, justifying the occurrence of some neurologic symptoms in association with these diseases. DESIGN: Surgical demonstration of complete excision of different types of peritoneal retraction pockets and a comparison with a laparoscopic retroperitoneal cadaveric dissection of the pelvic innervation. SETTING: Private hospital in Curitiba, Paraná, Brazil. INTERVENTIONS: A pelvic peritoneal pocket is a retraction defect in the surface of the peritoneum of variable size and shapes [1]. The origin of defects in the pelvic peritoneum is still unknown [2]. It has been postulated that it is the result of peritoneal irritation or invasion by endometriosis, with resultant scarring and retraction of the peritoneum [3,4]. It has also been suggested that a retraction pocket may be a cause of endometriosis, where the disease presumably settles in a previously altered peritoneal surface [5]. These defects are shown in many studies to be associated with pelvic pain, dyspareunia, and secondary dysmenorrhea [1-4]. Some studies have shown that the excision of these peritoneal defect improves pain symptoms and quality of life [5]. It is important to recognize peritoneal pockets as a potential manifestation of endometriosis because in some cases, the only evidence of endometriosis may be the presence of these peritoneal defects [6]. In this video, we demonstrate different types of peritoneal pockets and their close relationship with pelvic anatomic structures. Case 1 is a 29-year-old woman, gravida 0, with severe dysmenorrhea and catamenial bowel symptoms (bowel distension and diarrhea/constipation) that were unresponsive to medical treatment. Imaging studies were reported as normal, and a laparoscopy showed a posterior cul-de-sac peritoneal pocket infiltrating the pararectal fossa, with extension to the lateral border of the rectum. Case 2 is a cadaveric dissection of a posterior cul-de-sac peritoneal pocket infiltrating the pararectal fossa, with extension to the pelvic sidewall. After dissection of the obturator fossa, we can observe that the pocket is close to the sacrospinous ligament, pudendal nerve, and some sacral roots. Case 3 is a 31-year-old woman, gravida 1, para 1, with severe dysmenorrhea that was unresponsive to medical treatment and catamenial bowel symptoms (catamenial bowel distention and diarrhea). Imaging studies were reported as normal and a laparoscopy showed left uterosacral peritoneal pocket infiltrating the pararectal fossa in close proximity to the rectal wall. Case 4 is a cadaveric dissection of the ovarian fossa and the obturator fossa showing the proximity between these structures. Case 5 is a 35-year-old woman, gravida 0, with severe dysmenorrhea that was unresponsive to medical treatment, referring difficulty, and pain when walking only during menstruation. A neurologic physical examination revealed weakness in thigh adduction, and the magnetic resonance imaging showed no signs of endometriosis. During laparoscopy, we found a peritoneal pocket infiltrating the ovarian fossa, with involvement in the area between the umbilical ligament and the uterine artery. This type of pocket can easily reach the obturator nerve. Because the obturator nerve and its branches supply the muscle and skin of the medial thigh [7,8], patients may present with thigh adduction weakness or difficulty ambulating [9,10]. Case 6 is a cadaveric dissection of the sacrospinous ligament and the pudendal nerve from a medial approach, between the umbilical artery and the iliac vessels. Case 7 is a 34-year-old woman, gravida 1, para 1, with severe dysmenorrhea and catamenial bowel symptoms as well as deep dyspareunia. The transvaginal ultrasound showed focal adenomyosis and a 2-cm nodule, 9-cm apart from the anal verge, affecting 30% of the bowel circumference. In the laparoscopy, we found a posterior cul-de-sac retraction pocket associated with a large deep endometriosis nodule affecting the vagina and the rectum. In all cases, endometriosis was confirmed by histopathology, and in a 6-month follow-up, all patients showed improvement of bowel, pain, and neurologic symptoms. CONCLUSION: Peritoneal pockets can have different clinical presentations. Depending on the topography and deepness of infiltration, they can be the cause of some neurologic symptoms associated with endometriosis pain. With this video, we try to encourage surgeons to totally excise these lesions and raise awareness about the adjacent key anatomic structures that can be affected.

Deep infiltrating endometriosis frequently affects the rectosigmoid region. It clinically presents as a chronic painful condition affecting women in their reproductive time. Here, we present a case of a 28-yr-old female patient who had a history of dysmenorrhea, dyspareunia, chronic abdominal and pelvic pain, and constipation secondary to rectal wall endometriosis. Microscopic examination of the resected rectal segment showed endometriosis with vascular and lymph node involvement. Vascular involvement is an uncommon histologic finding that may raise concern for potential malignancy. The aim of this report is to alert pathologists and physicians about this infrequent pitfall that can be mistaken for a neoplastic process and to discuss the underlying pathophysiology of vascular involvement by endometrial tissue in otherwise benign conditions.

RESUMEN Introducción: se sabe que las concentraciones plasmáticas de hormona antidiurética o vasopresina son más altas en las mujeres con dismenorrea primaria (DiPr) y podría ser causa de retención de agua con signos y síntomas concomitantes que agravan su cuadro clínico. La monoterapia con AINEs en ocasiones alcanza solo un alivio parcial porque no incide sobre la vasopresina. Objetivo: evaluar la eficacia y tolerabilidad del dexketoprofeno + pamabrom en la DiPr tomando como referencia el acetaminofén. Materiales y métodos: estudio doble ciego, controlado, randomizado, en pacientes con DiPr asignados al azar. Fueron aleatorizadas 172 pacientes, 86 en cada grupo 1) Grupo casos (DP): dexketoprofeno + pamabrom o 2) Grupo control (AC): acetaminofén. Se evaluó la evolución de la intensidad del dolor, el alivio del dolor, la gravedad de otros síntomas presentes y la satisfacción global del médico y paciente. Se registró las reacciones adversas. Resultados: la disminución de la intensidad del dolor, de los síntomas acompañantes y el alivio del dolor evaluados por la EVA, la PID, la SPID, el PAR y el TOTPAR respectivamente es mayor y más rápida de modo significativo en todos los tiempos para la combinación DP. Las reacciones adversas fueron mínimas. La satisfacción global de pacientes y médicos respecto al tratamiento es significativa a favor de la combinación DP. Conclusiones: dexketoprofeno + pamabrom es significativamente más eficaz y rápido en el control del dolor y otros síntomas presentes en la dismenorrea primaria que acetaminofén demostrando la validez de añadir un diurético suave a un AINE para incrementar su eficacia. El tratamiento DP es bien tolerado (AU).
ABSTRACT Background: It is known that plasma concentrations of antidiuretic hormone or vasopressin are higher in women with primary dysmenorrhea (DiPr) and could cause water retention with concomitant signs and symptoms that aggravate the illness. Monotherapy with NSAIDs sometimes achieves only partial relief because it does not affect vasopressin. Objective: The aim was to evaluate the efficacy and tolerability of dexketoprofen + pamabrom in DiPr taking as reference acetaminophen. Materials and methods: Double-blind, controlled, randomized study in patients with DiPr random to 1) Case group (PD): dexketoprofen + pamabrom or 2) Control group (CA): acetaminophen. The evolution of pain intensity, pain relief, severity of other present symptoms and overall satisfaction of the doctor and patient were evaluated. Adverse reactions were recorded. Results: 172 patients were randomized, 86 in each group. The decrease in pain intensity, accompanying symptoms and pain relief evaluated by VAS, PID, SPID, PAR and TOTPAR respectively is significantly greater and faster at all times for the combination DP. Adverse reactions were minimal. The overall satisfaction of patients and doctors regarding treatment is significant in favor of the DP combination. Conclusions: Dexketoprofen + pamabrom is significantly more effective and faster in the control of pain and other symptoms present in primary dysmenorrhea than acetaminophen demonstrating the validity of adding a mild diuretic to an NSAID to increase its effectiveness. DP treatment is well tolerated (AU).

Abnormal menstruation may result in several pathological alterations and gynaecological diseases, including endometriosis, menstrual pain and miscarriage. However, the pathogenesis of menstruation remains unclear due to the limited number of animal models available to study the menstrual cycle. In recent years, an effective, reproducible, and highly adaptive mouse model to study menstruation has been developed. In this model, progesterone and oestrogen were administered in cycles following the removal of ovaries. Subsequently, endometrial decidualisation was induced using sesame oil, followed by withdrawal of progesterone administration. Vaginal bleeding in mice is similar to that in humans. Therefore, the use of mice as a model organism to study the mechanism of menstruation and gynaecological diseases may prove to be an important breakthrough. The present review is focussed ond the development and applications of a mouse model of menstruation. Furthermore, various studies have been described to improve this model and the research findings that may aid in the treatment of menstrual disorders in women are presented.

OBJECTIVE: Research suggests that medical students as well as women are at greater risk of depression compared to the general population and men. This suggests that female medical students are crucial targets requiring specific monitoring for mental health disorder prevention and intervention. However, little is known regarding the risk factors for poor mental health among this population. Therefore, we investigated whether menstrual symptoms and nutritional status are associated with psychological distress in Japanese female medical students. METHODS: This cross-sectional study assessed 326 female medical students who attended a school medical check-up, which included blood sampling in 2018. The levels of psychological distress were evaluated using the Japanese General Health Questionnaire (J-GHQ)-30. We defined high GHQ scores as GHQ-30 ≥7. We checked dysmenorrhea levels and assessed menstrual symptoms according to the presence of premenstrual syndrome (PMS). Dysmenorrhea was evaluated according to quartiles of the sum of the Menstrual Distress Questionnaire (MDQ). PMS was assessed using the Premenstrual Symptoms Questionnaire (PSQ). We evaluated levels of serum albumin, hemoglobin, ferritin, and lipid metabolite as nutritional factors. A multivariate logistic regression analysis was used to identify the association between menstrual-related symptoms or nutritional factors and the levels of psychological distress. RESULTS: A total of 45 female medical students (15%) experienced psychological distress. Serum albumin levels were associated with psychological distress, while lipid metabolite levels were not. The intensity of dysmenorrhea and the presence of PMS were associated with psychological distress, independent of nutritional status. CONCLUSION: Both menstrual symptoms and nutrition markers were associated with the levels of psychological distress in Japanese female medical students. School doctors and nurses can help improve the mental health of young female medical students by encouraging a healthy diet and checking for the presence of menstrual symptoms.

Studies have been published on the efficacy of Dienogest in the management of pain symptoms in endometriosis. Nonetheless, few data are available on the reducing effect on endometrioma's size. The aim of the study was to evaluate if Dienogest could determine significant changes in size, as well as in symptoms. In this prospective observational study, patients were enrolled with pain symptoms and at least one endometrioma diagnosed via TV-US. The volume of the endometrioma and pain symptoms was measured according to the LxDxWx0.5233 formula and VAS, respectively. Dienogest 2 mg was administered daily. Follow-up visits were scheduled after 6 and 12 months of treatment to assess changes in patients' symptoms and endometrioma's volume. Seventy patients were enrolled, 63 patients completed a 6-month treatment. The reduction of the mean volume after 6 months was 66.71%. Fifty-eight patients completed the 12 month-treatment. The reduction of the mean volume after 12 months was 76.19%. Dysmenorrhea showed a 74.05% reduction after 6 months and a 96.55% reduction after 12 months. Patients reported a reduction in dyspareunia and chronic pelvic pain of 42.71% and 48.91% after 6 months and 51.93% and 59.96% after 12 months, respectively. Dienogest leads to a statistically significant reduction of endometrioma's volume and pain symptoms.

AIM OF THIS STUDY: This study aims to assess the effectiveness of herbal medicines on relieving primary dysmenorrhea in a murine model and to delineate a plausible mechanism. MATERIALS AND METHODS: Herbal medicines in the form of pills (Wan) or capsules, including Gui-Zhi-Fu-Ling capsule, Gui-Zhi-Fu-Ling-Wan, Jia-Wei-Xiao-Yao-Wan, and Shao-Fu-Zhu-Yu capsule were purchased from local drug stores in Nanjing. Dang-Gui-Shao-Yao-San filled from a local hospital. The identity of the drugs was validated by HPLC profiling. Female ICR mice were used for an induced dysmenorrhea model. The severity of dysmenorrhea was evaluated and scored, the motor coordination and balance affected by induced dysmenorrhea was assessed by a Rotarod test. Uterine inflammation and edema were examined after histological and immunohistochemical staining. The effect of the drugs on COX2 activity was evaluated enzymatically. RESULTS: The Chinese herbal medicines at dosages relevant to recommended uses in humans relieved painful responses, including abdominal wall contraction, pelvic twisting and/or rear limb stretching. The treatment also improved motor coordination, extending the time staying on a rotating rod from 2.64⯱â¯0.38â¯min of oxytocin-induced group to 8.59⯱â¯1.45 (DGSYs), 9.50⯱â¯1.47 (GZFLc), 8.04⯱â¯1.87 (GZFLw), 9.91⯱â¯1.62 (JWXYw), and 8.20⯱â¯1.35â¯min (SFZYc), respectively. H&E staining showed that treatment with ibuprofen or Chinese herbal medicines markedly decreased edema and inflammatory cell infiltration in uterine tissues. The treatment did not significantly affect pattern of COX2 staining. In an in vitro enzymatic assay, the Chinese herbal medicines showed strong inhibitory activity against cyclooxygenase-2. The aqueous extracts from P. lactiflora or P. suffruticosa, two of the common components in the formulae tested, also showed anti-dysmenorrhea activity in the rotarod assay. CONCLUSION: The study demonstrates that traditionally used Chinese herbal medicines are effective against induced-dysmenorrhea. These herbal medicines relieve dysmenorrhea symptoms likely though inhibition of cyclooxygenase activity.

BACKGROUND: The combination of intrapelvic and extrapelvic endometriosis is a very rare condition in gynecology. Patients with endometriosis involving the sciatic nerve are easily misdiagnosed because they usually present with atypical symptoms of endometriosis. Here, we present a rare case of an endometrioma passing through the left greater sciatic foramen. Removal of the endometriotic lesion was performed with a concomitant laparoscopic and transgluteal approach through the cooperation of gynecologists and orthopedic (neuro)surgeons. CASE PRESENTATION: A 20-year-old woman presented with complaints of severe dysmenorrhea lasting for more than 6 years and dysfunction of her left lower limb lasting for approximately 4 months. Both CT and MRI demonstrated a suspected intrapelvic and extrapelvic endometriotic cyst (7.3 cm × 8.1 cm × 6.5 cm) passing through the left greater sciatic foramen. Laparoscopic exploration showed a cyst full of dark fluid occupying the left obturator fossa and extending outside the pelvis. A novel combination of transgluteal laparoscopy was performed for complete resection of the cyst and decompression of the sciatic nerve. Postoperative pathology confirmed the diagnosis of endometriosis. Long-term follow-up observation showed persistent pain relief and lower limb function recovery in the patient. DISCUSSION AND CONCLUSIONS: When a woman complains of unexplained unilateral sciatica, especially a woman suffering from dysmenorrhea, endometriosis of the sciatica nerve should be considered as a potential etiology. Complete excision of the endometriotic lesion and adequate neurolysis (or decompression) of the sciatic nerve through the multidisciplinary cooperation of experienced gynecologists with proper training in laparoscopic pelvic (neuro)surgery and orthopedic (neuro)surgeons is effective.

PURPOSE: Deep infiltrating endometriosis (DIE) is defined as an endometriotic lesion penetrating to a depth of >5 mm and is associated with pelvic pain, but the underlying mechanisms are unclear. Our objective is to investigate whether plasminogen activator inhibitor-1 expression (PAI-1) in endometriotic tissues is increased in women with DIE. METHODS: In this blinded in vitro study, immunohistochemistry and Histoscore were used to examine the expression of PAI-1 in glandular epithelium (GECs) and stroma (SCs) in a total of 62 women: deep infiltrating uterosacral/rectovaginal endometriosis (DIE; n = 13), ovarian endometrioma (OMA; n = 14), superficial peritoneal uterosacral/cul-de-sac endometriosis (SUP; n = 23), uterine (eutopic) endometrium from women with endometriosis (UE; n = 6), and non-endometriosis eutopic endometrium (UC; n = 6). The following patient characteristics were also collected: age, American Fertility Society stage, hormonal suppression, phase of menstrual cycle, dysmenorrhea score and deep dyspareunia score. RESULTS: PAI-1 expression in GECs and SCs of the DIE group was significantly higher than that of SUP group (p = 0.01, p = 0.01, respectively) and UE group (p = 0.03, p = 0.04, respectively). Interestingly, increased PAI-1 expression in GECs and SCs was also significantly correlated with increased dysmenorrhea (r = 0.38, p = 0.01; r = 0.34, p = 0.02, respectively). CONCLUSIONS: We found higher expression of PAI-1 in DIE, and an association between PAI-1 and worse dysmenorrhea.

Objective: To measure the uterine volume by ultrasonic imaging in nullipara patients with endometriosis and analyze its clinical significance. Methods: From July 1st, 2016 to August 1st, 2017, 107 cases of nullipara patients with endometriosis hospitalized in Peking University First Hospital were selected as endometriosis group. Among 107 cases, 59 cases were in proliferative phase of menstrual cycle, 48 cases were in secretory phase; and 10 cases had an abortion history.Totally 101 cases of patients without endometriosis operated for other benign disease during the same period were chosen as the control group. All patients underwent laparoscopic surgery, and the diagnosis was confirmed by pathology. The uterine size was measured by transvaginal or transrectal color Doppler ultrasound, and the uterine volume was calculated according to the known formula. Results: The uterine volume of the endometriosis group [(69±26) cm(3)] was larger than that of the control group [(54±18) cm(3), P<0.01]. In the endometriosis group, the uterine volume of patients with pregnant history [(78±34) cm(3)] was larger than that of patients without pregnant history [(68±25) cm(3)]. The endometrial thickness in endometriosis group was higher than that of the control group [(9.1±3.5) versus (7.8±2.9) mm, P<0.05], and positively correlated with the uterine volume (r=0.39, P<0.05). The hemoglobin in endometriosis group was lower than that in the control group [(124±12) versus (131±10) g/L, P<0.01], and was negatively correlated with the uterine volume in the two groups (r(endometriosis)=-0.12, r(control)=-0.21; both P<0.05).The uterine volume of dysmenorrhea patients in the endometriosis group [(73±28) cm(3)] was greater than that of patients without dysmenorrhea [(62±19) cm(3), P<0.01]; both uterine volumes of patients with and without dysmenorrhea in endometriosis group were larger than those of patients with or without dysmenorrhea in the control group (P<0.05). The degree of dysmenorrhea in endometriosis group was positively correlated with the uterine volume (r=0.20, P=0.042). The uterine volume of stage â £endometriosis patients [(79±30) cm(3)] was greater than that of stage â ¢ patients in endometriosis group [(58±14) cm(3), P<0.01]. Conclusion: Patients with endometriosis are of increased uterine volume, which may be related to dysmenorrhea, menorrhagia and infertility.
