The Role of Genistein and its Derivatives in Ovarian Cancer: New Perspectives for Molecular Mechanisms and Clinical Applications

Genistein (GEN) is a member of the polyphenol family, known chiefly for its effects on metabolic diseases and gynecological disorders. GEN has anti-cancer properties by inhibiting tumor proliferation, tumor metastasis, invasion, migration, and inducing apoptosis. Ovarian cancer (OC) is ranked 7th among the most common gynecological cancers. Despite its low incidence compared to other cancers, it is the first cause of death among gynecologic malignancies. Surgery and chemotherapy are the main options for treating this fatal cancer. Therefore, further investigations into GEN may aid in the discovery of novel therapeutics for preventing and/or treating OC. In this review, we aim to investigate the role of GEN in ovarian cancer. We investigate the anti-tumor effects of GEN on OC cell lines, including inducing apoptosis, suppressing tumor growth, and inhibiting metastasis. Also, we review the studies investigating GEN's roles as an adjuvant in therapeutic regimens with other chemotherapeutic agents (e.g., cisplatin, quercetin, and gemcitabine).

The Role of Quercetin for the Treatment of Endometriosis and Endometrial Cancer: A Comprehensive Review

Endometrial glands and stroma can be seen outside the uterine cavity in endometriosis, a gynecological disorder linked to estrogen dependency. Hormonal therapies, surgical excision, and non-steroidal anti-inflammatory drug therapy are among the traditional endometriosis treatments, however, various side effects limit their efficacy. Therefore, it is vital to research complementary and alternative therapeutic modalities to decrease the side effects of conventional therapies. While the search for the best endometriosis treatment continues, the focus is being paid to the assistance provided by polyphenols, notably quercetin. A broad spectrum of health-improving benefits of quercetin includes interactions with endometriosis-related molecular targets such as cell proliferation, apoptosis, invasiveness, inflammation, and oxidative stress. According to already-known research, medicines that mimic the physiological effects of quercetin are good candidates for creating novel endometriosis therapies. This review aims to comprehensively review quercetin's potential as a non-pharmacological treatment for endometriosis by interacting with several cellular and molecular targets.

Modulation of microRNAs expression and cellular signaling pathways through curcumin as a potential therapeutical approach against ovarian cancer: A review

Short non-coding RNAs called microRNAs (miRNAs) control gene expression by either inhibiting translation or degrading messenger RNA. MiRNAs are crucial for many biological functions, and the deregulation of their expression is strongly linked to the emergence of cancer. A single miRNA controls several gene expressions, allowing it to simultaneously control a number of cellular signaling pathways. As a result, miRNAs may be used as therapeutic targets as well as biomarkers for the prognosis and diagnosis of different cancers. Recent research has shown that natural compounds like curcumin, resveratrol and quercetin exert their pro-apoptotic and/or anti-proliferative impacts by modulating one and/or more miRNAs, which inhibits the growth of cancer cells, induces apoptosis, or increases the effectiveness of conventional cancer therapies. Here, we summarize the most recent developments in curcumin's control over the expression of miRNAs and emphasize the significance of these herbal remedies as a viable strategy in the treatment and prevention of cancer.

Lncrnas And Mirnas: New Targets For Resveratrol In Ovarian Cancer Research

Abstract:

Ovarian cancer (OC) is the 3rd common gynecologic cancer. Numerous procedures are involved in the growth of OC, like migration, angiogenesis, proliferation, apoptosis, invasion, and metastasis. Therefore, a better knowledge of the molecular processes complicated in ovarian tumorigenesis can lead to better measures for the prevention and treatment of the disease and its diagnosis. Long non-coding RNAs (LncRNAs), a subclass of non-coding RNAs, are much more diverse than previously thought. It is suggested that these RNAs may play a role in controlling complex cellular signaling mechanisms via binding to proteins and influencing their function. Nevertheless, our acquaintance with the participation of LncRNAs in the pathogenesis of OC is still restricted. Especially, we do not yet recognize how to pharmacologically correct the epi-mutations. Resveratrol, a natural polyphenol mostly derived from grapes, has been evaluated in many studies to find its cancer therapeutic potential. In the current paper, we aimed to review the role of resveratrol as a potential natural product on lncRNAs as novel diagnostic and therapeutic targets in OC and represent new insights for further investigations.

Hyaluronic acid gel application versus ovarian suspension for prevention of ovarian adhesions during laparoscopic surgery on endometrioma: a double-blind randomized clinical trial

Background

This study aimed to compare the effect of ovarian suspension and hyaluronic acid gel to prevent re-adhesions after laparoscopic endometrioma surgery.

Methods

This randomized clinical trial was conducted at Rasoul-e-Akram and Pars Hospitals, Tehran, Iran, 2016-18. Fifty patients with bilateral endometrioma and pelvic adhesions, the candidates of laparoscopic surgery, were included. In each patient, at the end of ovarian cystectomy and adhesiolysis, one of the ovaries was randomly sutured to the abdominal wall, and the HYAcorp Endogel covered the other; the adhesion rate was compared between the groups by ultrasonography, three-month after surgery.

Results

Mean age of patients was 32.6 years. Presurgical variables were similar between right and left ovaries and the study groups (P > 0.05). Postsurgical ultrasonography showed that ovarian soft markers, including < 1/3 ovarian adhesions (minimal adhesions) in 80.5% of ovaries of the Endogel group and 35.5% of the ovarian suspension group (P < 0.001) with higher ovarian mobility in the Endogel group (65% vs. 22%) (P = 0.001). In addition, site-specific tenderness and ovarian fading margin were lower in the Endogel group (P < 0.001).

Does endometriosis increase susceptibility to COVID-19 infections? A case-control study in women of reproductive age

BACKGROUND

In today's world, coronavirus disease 2019 (COVID-19) is the most critical health problem and research is continued on studying the associated factors. But it is not clear whether endometriosis increases the risk of COVID-19.

METHODS

Women who referred to the gynecology clinic were evaluated and 507 women with endometriosis (case group) were compared with 520 women without endometriosis (control group). COVID-19 infection, symptoms, exposure, hospitalization, isolation, H1N1 infection and vaccination, and past medical history of the participants were recorded and compared between the groups using IBM SPSS Statistics for Windows version 21.

RESULTS

Comparison between the groups represent COVID-19 infection in 3.2% of the case group and 3% of the control group (P = 0.942). The control group had a higher frequency of asymptomatic infection (95.7% vs. 94.5%; P < 0.001) and fever (1.6% vs. 0%; P = 0.004), while the frequency of rare symptoms was more common in the case group (P < 0.001). The average disease period was 14 days in both groups (P = 0.694). COVID-19 infection was correlated with close contact (r = 0.331; P < 0.001 in the case group and r = 0.244; P < 0.001 in the control group), but not with the history of thyroid disorders, H1N1 vaccination, traveling to high-risk areas, and social isolation (P > 0.05).

CONCLUSION

Endometriosis does not increase the susceptibility to COVID-19 infections, but alters the manifestation of the disease. The prevalence of the disease may depend on the interaction between the virus and the individual's immune system but further studies are required in this regard.

The effects of omega-3 fatty acids supplementation on metabolic status in pregnant women: a systematic review and meta-analysis of randomized controlled trials

Background and objective

Data regarding the effects of omega-3 polyunsaturated fatty acids (PUFA) supplementation on metabolic status of pregnant women are limited. This systematic review and meta-analysis were done based on randomized controlled trials (RCTs) dealing with the effects of omega-3 PUFA supplementation on glycemic control, lipoproteins, inflammation and oxidative stress in pregnant women.

Methods

Following databases were searched for eligible studies published from inception to until 2019: MEDLINE, EMBASE, Web of Science, PubMed, Scopus, Cochrane Library, and Google scholar. Studies that evaluated the effect of omega-3 PUFA supplementation on parameters of glycemic control, lipoproteins, inflammation and oxidative stress in pregnant women were found by using the key MeSH. A study quality assessment was performed using the Cochrane Collaboration risk of bias tool and heterogeneity between studies was statistically computed using Cochrane's Q test and I-square (I²). Data were pooled using a random-effects model and weighted mean difference (WMD) was considered as the overall effect size.

Results

No significant effects of omega-3 PUFA supplementation on FPG, insulin, insulin resistance, total cholesterol, triglycerides, LDL-cholesterol, total cholesterol/HDL-cholesterol, interleukin 6 (IL-6), IL-8, and malondialdehyde were found. However, omega-3 PUFA significantly increased serum concentrations of HDL-cholesterol (WMD: 3.10; 95% CI: 0.18, 6.03) and reduced C-reactive protein (WMD: -1.85; 95% CI: -2.61, -1.09).

Conclusion

Based on the results of this meta-analysis omega-3 PUFA supplementation during pregnancy has a significant beneficial effect on HDL-cholesterol, and C-reactive protein.

Evaluation of the frequency and diagnostic delay of primary immunodeficiency disorders among suspected patients based on the 10 warning sign criteria: A cross-sectional study in Iran

INTRODUCTION

The prevalence of undiagnosed primary immunodeficiency diseases is remarkably high and contributes to increasing the rate of morbidity and mortality among this group of patients.

OBJECTIVE

To examine the 10 warning sign scoring system in patients suspected of primary immune deficiency and also estimate the diagnostic delay in patients with proven disease.

METHODS

This descriptive cross-sectional study was carried out during the years 2015-2016 in Ali Asghar (AS) Clinic and Hospital. Two hundred patients with suspected primary immune deficiency disease were eligible for inclusion in the study. Multivariable logistic regression analysis was used to determine the relation between findings.

RESULTS

In this study, the majority of suspected cases of immunodeficiency were males (57%) with a mean age of 3.33±2.89 years. Twenty-one (10.5%) patients were diagnosed with immunodeficiency disease. The mean diagnostic delay among primary immune deficient patients was 2.05±1.7 years. There was a significant relationship between having parental consanguinity (OR=2.68, 95% CI: 1.07-6.70), allergies (OR=5.03, 95% CI: 1.13-22.31), vaccine adverse effects (OR=9.31, 95% CI: 1.24-69.96) and primary immune deficiency diagnosis. No association was observed between age (OR=0.98, 95% CI: 0.84-1.14), gender (OR=0.99, 95% CI: 0.39-2.47), immune deficiency scoring (OR=0.68, 95% CI: 0.31-1.45) and primary immune deficiency diagnosis.

CONCLUSION

Ten warning sign scoring system is of less value to consider a patient suspected of having primary immune deficiency. There is a meaningful delay in diagnosis of primary immune deficiencies especially in antibody deficiency defects which seeks further upgrading of knowledge in physicians.

Circular RNA as a potential diagnostic and/or therapeutic target for endometriosis

Endometriosis is a pathology form of endometrium that behaves in a similar way to malignancies, such as invasion and resistance to apoptosis. Circular RNAs (CircRNAs) are a class of noncoding RNAs that have several biological functions including, miRNA sponging, sequestering of proteins, enhancing parental gene expression and translation resulting in polypeptides. In this review, we highlighted the roles of circRNAs as potential diagnostic and therapeutic biomarkers in endometriosis. Moreover, we summarized the roles of circRNAs in the pathogenesis of endometriosis via different signaling pathways, such as the miRNA network and apoptosis.

Anti-tumor activities of probiotics in cervical cancer

Cervical cancer is considered as an important malignancy among women worldwide. Currently-used treatments of cervical cancer are reported to be cytotoxic for patients. Moreover, these therapies have shown some side effects which can negatively affect the lives of women suffering from this cancer. Therefore, there is need for anti-tumor agents that are less toxic than common therapeutic drugs. Besides, applying agents for preventing or reducing the side effects of cervical cancer therapies can be effective in improving the life quality of cervical cancer patients. Studies have shown that probiotics have several effects on biological processes. One of the most prominent aspects in which probiotics play a role is in the field of cancer. There are multiple studies which have focused on the functions of probiotics in diagnosis, prevention, or treatment of cancer. Besides their direct anti-tumor activities, probiotics can be used as an additional agent for enhancing or modulating other diagnostic and therapeutic methods. Herein, the effects of probiotics on cervical cancer cells are discussed, which may be useful in the prevention and treatment of this cancer. We review the studies concerned with the roles of probiotics in modulating and reducing the gastrointestinal adverse effects caused by cervical cancer therapies. Furthermore, we cover the investigations focusing on the combination of probiotics with other drugs for diagnosis or treatment of cervical cancer.

COVID-19 and pregnancy: a review of current knowledge

BACKGROUND

Since December 2019, coronavirus disease 2019 (COVID-19) has become a major health problem that is spreading all over the world. Several viral infections such as SARS, MERS, and influenza have been associated with adverse pregnancy outcomes. The question arises whether pregnant women are at greater risk of complications related to COVID-19 compared to other people What complications should we expect in the fetuses whose mothers were infected?

AIMS

This review aims to provide a summary of studies on symptoms of COVID-19 and the possible risks of COVID-19 among pregnant women, as well as complications in fetuses and neonates whose mothers were infected with COVID-19.

METHODS

The included data were provided from Web of Science, Cochrane, PubMed, and Scopus which are extracted from the published studies in English until April 2nd, 2020 that contained data on the risk of COVID-19 in pregnancy.

RESULTS

The early symptoms of patients with COVID-19 were fever, cough, dyspnea, myalgia, and fatigue; while production of sputum, headache, hemoptysis, and diarrhea were other symptoms which were less common. There is no evidence of vertical maternal-fetal transmission in pregnant women with COVID-19.

CONCLUSIONS

The clinical findings in pregnant women with COVID-19 are not significantly different compared to other patients, and pregnant women with COVID-19 are not at a higher risk of developing critical pneumonia compared to non-pregnant women. Although, there has been no sign of vertical infection in infants, but maternal infection can cause serious problems such as preterm labour and fetal distress.

Functional activities of beta-glucans in the prevention or treatment of cervical cancer

Cervical cancer is the fourth-ranked cancer in the world and is associated with a large number of deaths annually. Chemotherapy and radiotherapy are known as the common therapeutic approaches in the treatment of cervical cancer, but because of their side effects and toxicity, researchers are trying to discovery alternative therapies. Beta-glucans, a group of glucose polymers that are derived from the cell wall of fungi, bacteria, and etc. it has been showed that beta-glucans have some anti-cancer properties which due to their impacts on adaptive and innate immunity. Along to these impacts, these molecules could be used as drug carriers. In this regard, the application of beta-glucans is a promising therapeutic option for the cancer prevention and treatment especially for cervical cancer. Herein, we have summarized the therapeutic potential of beta-glucans alone or as adjuvant therapy in the treatment of cervical cancer. Moreover, we highlighted beta-glucans as drug carriers for preventive and therapeutic purposes.

Chitosan is a potential inhibitor of ovarian cancer: Molecular aspects

Although ovarian cancer has a lower prevalence than breast cancer, its mortality rate is three times higher, which is reported to increase in the coming years. As the early stages of ovarian cancer do not have any obvious symptoms, in most of the cases, this cancer is diagnosed at advanced stages with a poor prognosis. Moreover, in many patients who are diagnosed with advanced stage, relapse of the disease and drug resistance are observed. Over the past years, these women have been treated with chemotherapy and cytoreductive surgeries. However, the chemotherapy could affect the healthy tissues in addition to the malignancies. Therefore, discovering new diagnostic and therapeutic options seems to be a crucial need. Unlike the common invasive and/or nonspecific treatments, nanomedicine is trying to find a new way for cancer imaging, diagnosis, and drug delivery method. Nanoparticles (NPs), which has recently drawn attention, can be used in order to reduce the toxicity and frequent dosing of drugs, tumor-specific delivery, and early diagnosis for malignancies. Chitosan as an NP and product of chitin deacetylation has multiple characteristics, including biocompatibility, biodegradability, and safety. In this review, we cover the studies concerned with the role of chitosan in finding solutions to overcome the problems faced in ovarian cancer treatments. Furthermore, we highlight how chitosan is being used in delivering chemotherapy drugs, gene therapy, and imaging methods for both detection and image-guided therapies.

A Systematic Review and Bioinformatics Study on Genes and micro-RNAs Involving the Transformation of Endometriosis into Ovarian Cancer

BACKGROUND

Along with the description of tumorigenesis processes in endometriosisrelated ovarian cancer, identifying dysregulated miRNAs, the target genes of these miRNAs, and the processes abnormally affected by dysregulated miRNAs is essential, which was our goal.

METHODS

Two reviewers individually evaluated the articles which collected relevant information including genes and miRNAs involved in the transformation of endometriosis into ovarian cancer. To assess the mature sequence of miRNAs and also their chromosomal positions, miRPathDB software was employed. To determine the main target gene predicted for each considered miRNAs, the TargetScanS Web server was applied. The interaction of each gene with other genes associated with endometrial- related ovarian cancer was determined by GeneMANIA software. Finally, to design integrated model of miRNAs-targeted genes interaction network, the Cytoscape software was used.

RESULTS

The final number of studies available for analysis was 6 manuscripts including 22 miRNAs described as involved in the transformation of endometriosis into different subtypes of ovarian cancers (14 miRNAs up-regulated and 8 miRNAs down-regulated). Three miRNAs of miR-141 (upregulated), miR-205 (down-regulated), and miR-125b (down-regulated) were revealed as the originator for genetic interactions leading to carcinogenesis. We could show some common loops and pathways including uncontrolled cell proliferation and abnormal apoptosis (mediated by PTEN gene induced by miR-21 and miR-214), and disaggregation and epithelialization (mediated by ZEB1 and ZEB2 genes induced by miR-200).

CONCLUSION

According to our analysis, up-regulation of miR-141 and down-regulation of miR-205 and miR-125b have a central role in transforming endometriosis to ovarian cancer.

Could circRNA be a new biomarker for pre-eclampsia?

Pre-eclampsia is a devastating complication of pregnancy which is characterized by hypertension and proteinuria in pregnant women. Pre-eclampsia is important as it is the leading cause of death. Moreover, untreated pre-eclampsia might lead to other lethal complications, for both fetus and mother. Pre-eclampsia can also affect the quality of life in affected women. Despite a large number of risk factors for pre-eclampsia, these risk factors are able to detect just 30% of women who are susceptible to pre-eclampsia. Heterogeneous manifestations of pre-eclampsia necessitate the discovery of potential biomarkers required for its early detection. Circular RNAs (circRNAs) are a type of RNA which are more abundant, specific, and highly organized compared with other types of RNA. Accordingly, circRNAs have been suggested as one of the potential biomarkers for different diseases. Recently, researchers have shown interest in the effects of circRNAs in pre-eclampsia, although the current evidence is limited. The majority of obstetricians are probably not aware of circRNAs as a useful biomarker. Here, we aimed to summarize recent supporting evidence and assess the mechanisms by which circRNAs are involved in pre-eclampsia.

Circular RNAs: A novel biomarker for cervical cancer

Besides messenger RNAs, recent RNA-Seq and biochemical analysis showed another type of RNAs as a product of splicing which is named circular RNA (circRNA). Evidence demonstrated that circRNAs are abundant in the cells and are able to show cell/tissue-specific expression or tissue developmental stage which suggest that circRNAs may have regulatory potentials. In recent years, researchers have focused attention on circRNAs because of their key functions in various cellular mechanisms. CircRNAs also have the potential to be as promising biomarkers for diagnosis of various diseases such as cancer. Growing up evidence has shown the various roles of circRNAs in multiple cancers. In recent years, cervical cancer as one of the main causes of cancer death in women has been interesting for molecular research. CircRNAs are one of the novel objects which have recently been evaluated in this cancer. The improvement in our knowledge of the roles of circRNAs in cervical cancer may lead to new transcription therapeutic approaches to cervical cancer inhibition. Therefore, the purpose of this review is to review many studies which examined the role of circRNAs in cervical cancer carcinogenesis and progression up till date and to summarize possible mechanisms of action of circRNAs in cervical neoplasm.

Sleep Quality and its Main Determinants Among Staff in a Persian Private Hospital

BACKGROUND

Having good quality of sleep is essential to good health. Sleep disorders could incur intangible expenses. The aim of this cross-sectional study was to evaluate the Persian version of the Pittsburgh Sleep Quality Index (PSQI-P) questionnaire administered to 3 categories of workers (clinical personnel, clerical staff, and logistics workers) in a private hospital located in Tehran, Iran.

METHODS

In 2017, all Pars hospital personnel were invited to participate in the study. The PSQI-P questionnaire was distributed among Pars hospital staff, who consented to take part in the study.

RESULTS

The total personnel in this private hospital was 1151 and 552 of them submitted their answers. According to the statistical analysis performed using SPSS version 19, there was no correlation between sleep quality and gender, marital status, age, job, shift work, or university degree (P value: 0.94, 0.42, 0.59, 0.67, 0.12, 0.23, respectively). However, participants with a lower body mass index (BMI) experienced better overnight sleep quality than overweight and obese participants (P value: 0.025 and 0.032, respectively). In addition, the prevalence of poor sleep quality was higher in those living in the suburbs compared to urban residents (P value: 0.02).

CONCLUSION

The study obtained a significant difference in sleep quality based on the participants' BMI and place of residence. Despite the fact that the P value of the job was not significant, it appeared that sleep disorders are common among clinical personnel. Quality of life may be improved by modification of the factors responsible for poor sleep quality.

The Controversy of the Most Proper Time for Pregnancy After Bariatric Surgery: a Review of Ten Cases

BACKGROUND

Many infertile obese women conceive after bariatric surgery after many years, while guidelines prohibit them from pregnancy for at least 12-18 months after surgery, due to complications.

METHODS

We hereby present 11 cases in our research center, pregnant in less than 12 months after surgery from 2011 to 2015, to evaluate their pregnancy outcome and complications.

RESULTS

The mean conception time was 3.6 months after surgery and mean birth weight was 2695 g. Regarding neonatal/fetal complications, there was one case of intrauterine growth retardation and one NICU hospitalization. Among pregnancy complications, eight patients had hyperemesis gravidarum and one had pre-eclampsia.

CONCLUSIONS

The results of the present study suggest revising setting a contraindication for conception for patients undergoing bariatric surgery.

A New Approach to an Old Concept for Reducing Shoulder Pain Caused by Gynecological Laparoscopy

BACKGROUND

The purpose of this study was to introduce a technique to extract the remaining peritoneal gas in order to improve the post-laparoscopic shoulder pain.

METHODS

This study included 12 patients undergoing laparoscopic gynecologic procedures between February and March 2016 in Minimally Invasive Techniques Research Center, Pars Hospital, Tehran, Iran. For complete suction of the air from abdominal cavity, the air was first vacuumed from the pelvic cavity in Trendelenburg position and then the patients were put in anti-Trendelenburg position. In this position, as the remaining gas was shifting toward subdiaphragmatic area, the suction tube was shifted to a position next to the camera canal and the remaining air was suctioned. A 10 point visual analogue scale was used to measure the severity of patients' post-operative shoulder pain.

RESULTS

The mean VAS for shoulder pain was 0.8±1.7 4 hr post-surgery. At 12 hr post-surgery, the mean VAS was 0.8±1.5. At 24 hr post-surgery, the mean VAS for shoulder pain was 0.3±0.8. Finally, 48 hr post-surgery, the VAS score for all patients was zero.

CONCLUSION

Our approach for emptying the abdominal cavity from residual gas after laparoscopic procedures seems to be useful in preventing post-operative shoulder pain among patients undergoing gynecological laparoscopic surgeries. Further studies are suggested to compare the effect of our proposed method with other methods.

Primary immunodeficiency diseases in Northern Iran

INTRODUCTION

Primary immunodeficiency diseases (PID) are a heterogeneous group of inherited disorders, characterised by recurrent severe infections, autoimmunity and lymphoproliferation. Despite impressive progress in identification of novel PID, there is an unfortunate lack of awareness among physicians in identification of patients with PID, especially in non-capital cities of countries worldwide.

RESULT

This study was performed in a single-centre paediatric hospital in Northern Iran during a 21-year period (1994-2015). Ninety-four patients were included in this study. The majority of cases had antibody deficiencies (37.23%), followed by well-defined syndromes with immunodeficiency in 16 (17.02%), phagocytic disorders in 15 patients (15.95%), complement deficiencies in 15 patients (15.95%), immunodeficiencies affecting cellular and humoral immunity in nine patients (9.57%), disease of immune dysregulation in three (3.19%), and defects in intrinsic and innate immunity in one (1.06%).

CONCLUSION

It seems that there are major variations in frequency of different types of PID in different regions of a country. Therefore, reporting local data could provide better ideas to improve the local health care system strategists and quality of care of PID patients.

Comparing the Efficacy of Surgery and Medical Therapy for Pain Management in Endometriosis: A Systematic Review and Meta-analysis

BACKGROUND

Pain is considered as one of the main symptoms of endometriosis. The treatment for endometriosis remains controversial.

OBJECTIVES

The aim of this study is to compare the effect of medical or surgical treatments for pain-relief in patients with endometriosis.

STUDY DESIGN

Systematic review and meta-analysis.

SETTING

Published papers about evaluating pain treatment in endometriosis in PubMed, Scopus, and Google Scholar.

METHODS

After searching all studies evaluating pain treatment in endometriosis in PubMed, Scopus, and Google Scholar, there were 23 related studies, containing 1,847 patients enrolled in our study. We used a variety of tests: fixed and random effects models, Q Cochrane test and I2 index, Egger and Begg tests, forest and funnel plots, Trim and fill method, and meta-regression in our analysis.

RESULTS

There was no statistically significant difference in pain improvement between surgical and medical treatment. Interestingly, pain relief was more prominent longer after treatment. Both clinical trials and cross sectional studies showed higher improvement in pain than cohort studies. High quality studies and lower body mass index (BMI) had a greater effect on pain relief. All studies were heterogeneous, but there was no publication bias.

LIMITATIONS

There was a higher probability of risk of bias in blinding, random sequence generation, and selective outcome reporting in clinical trial studies entered in our meta-analysis.

CONCLUSIONS

Our results could not demonstrate the preference of each medical or surgical treatment effect for dysmenorrhea in endometriosis. Additional data is required before a standardized medical protocol can be offered, but we believe this study may encourage clinicians to consider a less invasive alternative for treating their patients' chronic pelvic pain in the near future.Key words: Endometriosis, pain, meta-analysis, therapy, disease management.

The Use of Peritoneal Suction Drainage to Reduce Shoulder Pain Caused by Gynecological Laparoscopy

PURPOSE

To compare the outcomes of patients undergoing uncomplicated laparoscopic gynecologic procedures with and without drainage, and investigate the effects of drainage on postoperative shoulder pain, hospital stay and analgesic medications.

PATIENTS AND METHODS

In this randomized clinical trial, 92 patients undergoing uncomplicated laparoscopic gynecologic procedures at Pars Hospital, Tehran, Iran, between April 2012 and July 2014 entered the study. Patients were randomly divided into two groups: one group received a drain at the end of operation, whereas the second group didn't receive a drain. For patients closed with drainage, Hemovac plastic passive drains were inserted without negative pressure. Severity of the patients' postoperative shoulder pain was evaluated at rest using the 10-point visual analogue scale (VAS) at 12 h, 24 h, and 48 h after surgery.

RESULTS

There was no difference between the two groups regarding age, weight, height, BMI, the cause of surgery and the blood loss during the surgery. At 12 h and 24 h after surgery, the shoulder pain was statistically lower in the group with drainage (P < 0.001 for both). There was no statistically significant difference between mean VAS scores of the case and control group at 48 hours post-surgery (P = 0.806). A significantly higher postoperative demand for analgesics was observed in the control group (P < 0.001). There was no statistically significant difference between two groups regarding the length of hospital stay.

CONCLUSION

Our findings suggest that drainage may be useful to prevent postoperative shoulder pain among patients undergoing gynecological laparoscopic surgeries and decrease the need for pain medication. Further studies are recommended to assess the feasibility and cost effectiveness of using this method for reducing the postoperative shoulder pain.

Leiomyosarcoma of the Broad Ligament With Fever Presentation: A Case Report and Review of Literature

Introduction

Leiomyosarcoma is a rare gynecologic malignancy that accounts for less than 1% of gynecological malignancies. Leiomyosarcoma of the broad ligament is an even rarer condition. According to Gardner’s criteria, the diagnosis is made when the mass is completely separated from the uterus and adnexa. So far, 23 cases of primary leiomyosarcoma of the broad ligament have been reported in the literature published in English.

Case Presentation

In September 2014, a 55-year-old, gravida 3, para 3 woman with a BMI of 30 and a chief complaint of fever and dizziness was admitted to the infectious-diseases ward of the Pars general hospital affiliated with Iran University of Medical Sciences in Tehran, Iran. Her symptoms had begun two weeks before. The results of a fever workup and examination for infectious, metabolic, and immunologic problems were all negative. Imaging modalities revealed an endometrial polyp, two calcified myoma in the body of the uterus, and a solid, heterogeneous 70-mm mass in the right para-cervical space, posterior to the broad ligament, and far from the ovary. After surgery, a histologic report revealed leiomyosarcoma.

Conclusions

Although a leiomyosarcoma of the broad ligament is rare, practitioners should consider it when dealing with masses in the region of the broad ligament. If there is any suspicion of malignancy, especially in the presence of fever, it is recommended to avoid morcellation during laparoscopy.

A Rare Case of Gestational Gigantomastia with Hypercalcemia: The Challenges of Management and Follow up

BACKGROUND

Gigantomastia is a breast disorder marked by exaggerated rapid growth of the breasts, generally bilaterally. Since this disorder is very rare and has been reported only in sparse case reports its etiology has yet to be fully established. Treatment is aimed at improving the clinical and psychological symptoms and reducing the treatment side effects; however, the best therapeutic option varies from case to case.

CASE PRESENTATION

The present report described a case of gestational gigantomastia in a 30-year-old woman, gravida 2, parity 1, 17 week pregnant admitted to Pars Hospital, Tehran, Iran, on May 2014. The patient was admitted to hospital at week 17 of pregnancy, although her breasts initially had begun to enlarge from the first trimester. The patient developed hypercalcemia in her 32nd week of pregnancy. The present report followed this patient from diagnosis until the completion of treatment.

CONCLUSION

Although gestational gigantomastia is a rare condition, its timely prognosis and careful examination of some conditions like hyperprolactinemia and hypercalcemia is essential in successful management of this condition.

Human papillomavirus (HPV) prevalence and types among women attending regular gynecological visit in Tehran, Iran

BACKGROUND

Persistent infection by HPV is now recognized as the main cause of cervical cancer. HPV prevalence data is not yet available in Iran. This study is organized to evaluate type-specific HPV prevalence and to compare it with Pap smear results among Iranian women attending regular gynecological visits.

METHODS

A total of 851 women aged 18 - 65 years, attending regular gynecological visits, were retrospectively evaluated. HPV detection and genotyping was performed by use of Polymerase Chain Reaction (PCR) and Restriction Fragment Length Polymorphism (RFLP). Cytological evaluation was done by Papanicolaou method and the association between cytological results and HPV status was analyzed.

RESULTS

19 different HPV types were detected in 265 of the 851 specimens (31.1%). Overall HPV infection as well as infection with High Risk (HR) HPV types was highest in women aged 18 - 25 years and decreased with age. Type-specific prevalence of HPV-16 and 18 was 7.3% and 2.8%, respectively, and a large number of women (20.2%) were infected by HR HPV types other than HPV-16 and/or HPV-18. There was also an upward trend in the prevalence of HR HPV infections as the abnormality in cytology increased. The prevalence of HPV co-infection was 29.1% of HPV positive patients and declined from LSIL (18.2%) to HSIL (3.9%).

CONCLUSIONS

Our study indicated that the burden of HPV infection among Iranian females was higher in comparison with previous estimates reported from Iran. Furthermore, higher prevalence of premalignant changes in Iranian women infected with HR HPV types, other than vaccine types, should be considered in immunization programs and development of population-specific HPV vaccines. This remarkable difference in prevalence of HPV types among previous studies, confirms our need to further investigations on epidemiology of HPV infection in Iran.

Use of progestogens as an adjuvant to surgery in the treatment of stage I adenocarcinoma of the uterine corpus

Fifty-nine patients with proven stage I adenocarcinoma of the uterine corpus were treated by total abdominal hysterectomy and bilateral salpingo-oophorectomy, followed by gestronal hexanoate intramuscularly for 3 months and then medroxyprogesterone acetate orally for a prolonged period. In the 7-year period of study, there were no vaginal recurrences, but one patient suffered a recurrence in the inguinal lymph nodes and pelvis. Undesirable side effects did not occur. These results compare favourably with other reported studies in which surgery and radiotherapy were used.
