Ghaemmaghami F, Hasanzadeh M, Modarresgilanimadani M, Behtash N, Mousavi As, Ramezanzadeh F,
Volume 65, Issue 4 (3 2007)
Abstract

Background: The aim of this study was to compare the outcome of treatment for ovarian cancer patients who have been treated by gynecologist oncologists and patients who have been treated by general gynecologists or general surgeons.

Methods: We enrolled in this cohort retrospective study all patients diagnosed with primary ovarian cancer in Vali-e-Asr Hospital, Tehran, Iran, between April 1999 and January 2005. A total 157 consecutive patients with ovarian cancer were available for analysis. Of these, 60 patients were treated by gynecologist oncologists and 95 by general gynecologists, and two patients were treated by general surgeons.

Results: The number of patients who underwent optimal cytoreductive surgery (residual tumor <1 cm) was higher in the gynecologist oncologist group, than in the general gynecologist group (P<0.001). Repeated surgeries were required for a majority of patients in the general gynecologist group, while only a few patients in the gynecologist oncologist group needed a second operation (P<0.0001). The interval between the initial surgery and the beginning of chemotherapy was significantly longer in the gynecologist oncologist group compared to that of the general oncologist group (P=0.001). Overall survival and disease-free survival was considerably greater in the gynecologist oncologist group. Optimal cytoreductive surgery and stage of disease are prognostic factors in patients with ovarian cancer. We can therefore conclude that patients with ovarian cancer who are treated by gynecologist oncologists have a better outcome.

Conclusions: We suggest that patients requiring cytoreductive surgery for ovarian cancer be referred to a gynecologist oncologist rather than having a less specialized physician care for such cases.


 Category-semantic memory deficit in Multiple Sclerosis
Khatoonabadi Sar, Hadian Mr, Ghaffarpour M, Kahlaoui K, Hasanzadeh A,
Volume 66, Issue 10 (4 2009)
Abstract

Background: Many studies have shown that about 45-65% of multiple sclerosis (M.S) patients suffer from cognitive impairments. Semantic memory as one of the subcategories of cognition is quite important for effective communication. In the present study, category-semantic memory was studied in order to evaluate the semantic memory organization in normal individuals and MS patients.

Methods: Ninety voluntaries participated in this study. Participants comprise of 45 MS patients and 45 normal individuals. All participants were matched in terms of age, sex and education. Variables such as the reaction time and the number of correct responses for retrieval (recognition) of natural (animal and fruit) and artifact (object) words were measured in both groups by presentation software. Data analyzed by t-paired and One-Way ANOVA tests. Ethical committee of Tehran University of Medical sciences approved the study.

Results: The results of current study showed significant differences in reaction time and correct responses of artifact and natural categories between the MS and normal individuals (p<0.05). Furthermore, there was significant difference between reaction time and number of correct responses to natural and artifact categories in each group (p<0.05).

Conclusions: This study showed that the organization of semantic categorization as natural and artifact categories is still preserved in multiple sclerosis patients. However, the processing of semantic categorization was different in term of reaction time and number of correct responses between MS patients and normal subjects and the processing of semantic-memory is slower than normal individuals.

Volume 68, Issue 12 (6 2011)
Abstract

Background: Female genital tract sarcomas are rare but most aggressive tumors of mesodermal origin. Little is known about the pathogenesis, risk factors, optimal treatment and outcome of these diseases. Therefore, we aimed to evaluate the clinicopathologic characteristics of patients with genital sarcoma.

Methods: This is a retrospective, cross-sectional study. The medical records of 43 female patients with genital tract sarcoma, hospitalized during a 16-year period (from 1991-2007) were retrieved from the medical records office of Ghaem Hospital in Mashad, Iran. The demographic data extracted from the records.

Results: The mean age of the patients was 46.95 years (ranging from 3-77 years). The chief complaint of the patients was abnormal vaginal bleeding (69.8%). The mean interval between the onset of symptom to the pathological diagnosis of sarcoma was 8.53 months (ranging from 1-36 months). Histologically, the tumors included: leiomyosarcoma (79.1%), endometrial stromal sarcoma (18.6%) and embryonal rhabdomyosarcoma (2.3%). Three patients (7%) were in International Federation of Gynecology and Obstetrics (FIGO) stage I, 20(46.5%) in stage II, 6(14%) in stage III and 14(32.6%) in stage IV. 48.8% of the patients had undergone chemoradiotherapy.

Conclusions: In most cases, our patients were referred so late or the disease was recognized very late due to being rare. We should consider this disease for every patient with unusual vaginal bleeding especially in post menopause women who their sonography has reported uterine mass.

Volume 69, Issue 6 (6 2011)
Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Diabetes is a metabolic disorder affecting the whole body systems including the female reproductive organs. Moreover, diabetes is an important cause of infertility. Metformin is commonly used to control hyperglycemia in patients with diabetes. This study was done to evaluate the ultrastructural changes of ovarian follicles in diabetic rats and their response to metformin.
Methods: Thirty-six adult Sprague-Dawley female rats (170-210 g) were studied in three groups (Control, diabetic and metformin-treated rats). In the second and third groups, diabetes was induced by injection of streptozotocin (45 mg/kg). The rats in the third group were later treated by metformin monohydrochloride (100 mg/kg). At the end of the experiment, rats were sacrificed and their right ovaries were observed under transmission electron microscope. Quantitative data were analyzed by student t-test in SAS software.
Results: In comparison with the control group, significant decreases in zona pellucida thickness and the mean number of microvilli were observed (respectively, P<0.01 and P<0.001) in diabetic rats. Significant decreases in zona pellucida thickness were also observed in metformin-treated rats (P<0.05) but changes in the number of microvilli were non-significant. The number of organelles in oocyte cytoplasm was higher and they were natural or natural-looking in metformin-treated rats versus the diabetic ones. Reduction in the number of mitochondria and their ballooning cristae were of the most noticeable changes in diabetic rats.
Conclusion: Diabetes decreases the number of microvilli and oocyte organelles and diminishes zona pellucida thickness leading to structural changes in the organelles but metformin could improve the aforesaid conditions.

Eini P, Esna-Ashari F, Mobaien Ar, Hasanzadeh M,
Volume 70, Issue 2 (4 2012)
Abstract

Background: Brucellosis is one of the most common infectious diseases in Iran with very different clinical manifestations.

Methods: In this retrospective descriptive study, all patients with brucellosis, who were admitted in Farshchian Hospital in Hamadan, Iran in 2005 to 2010, were enrolled in the study. The data were collected from the patients' medical records and were entered in forms for analysis.

Results: A total of 230 patients with brucellosis, including 130 (56.5%) male and 100 (43.5%) female patients with a mean age of 40.84±20.29 years, who mostly (72.2%) lived in rural areas were enrolled in the study. Outbreaks were most common in spring and summer and the main route of transmission was consumption of contaminated dairy products (60.3%). The most common symptoms were fever (77.4%), arthralgia (70%), sweating (47%), malaise and fatigue (46.5%). Arthritis and epididymo- orchitis were seen in 121 (52.9%) and 48 (8.20%) patients, respectively. CBC analysis showed leukocytosis in 20.8% of the participants. ESR rise was noted in 59.5% of the patients and 52.9% had positive CRP.

Conclusion: Given to various clinical presentations, brucellosis should be considered in the differential diagnosis of individuals with chronic fever with or without other organ abnormalities.

Volume 73, Issue 7 (October 2015)
Abstract

Background: Ovarian sex cord-stromal tumors (SCST) account for rare ovarian malignancy. These tumors are 5-8% of all ovarian neoplasms. The most common type of sex cord ovarian tumors is granulosa cell tumor (GCT). In this study our purpose was to have a look at some of clinicopathologic aspects and treatment results of these tumors. Methods: In a retrospective study, all documents of patients with SCST was referred to tumor clinics of Ghaem and Omid Hospitals, from 1998 to 2008. The data of patients were collected and analyzed. Results: In 39 (5.9) of the 398 cases, ovarian malignancies was present in SCST. Eight Patients omitted from the study because there were not enough data for them. The commonest pathology was adult granulosa cell tumor in 25 patients (80.6%). Two patients (8.33%) had juvenile granulosa cell tumor, they were 25 and 38 years old. At time of diagnosis, 27 cases (87.1%) were in early stages (stage I). Mean age of patients was 41 years (range 16-76 years) at time of diagnosis of disease. Surgical staging of cancer was performed in 14 patients (46.7%). We did fertility sparing surgery in 12 patients (40%). Two patients were pregnant after surgery. 17 patients (54.80%) did not receive chemotherapy. Three patients (9.7%) received radiotherapy. Overall survival rates were 95% at both 2 years and 5 years. Longer survival had correlation with early stages of disease (P= 0.002). Age, conservative surgery and chemotherapy had no correlations with survival. Conclusion: The prognosis of SCST is almost good. Most of the patients were diagnosed in early stage of disease. In sex cord ovarian tumor, the only factor that have a full effect on survival, is stage of the disease. If the patients desire to preserve fertility, we can do fertility sparing surgery with minimal effect on survival.

Volume 74, Issue 4 (July 2016)
Abstract

Background: Gestational trophoblastic neoplasia (GTN) consists of a broad spectrum of benign and malignant tumors which are stem in human placental trophoblast. Vitamin D has several biologic rules. Among the effects of vitamin D on cells, we could mention induction of differentiation and apoptosis and also inhibition of proliferation, angiogenesis and metastatic potency. As nutrition plays a pivotal rule in GTN, in this study we compared serum 25-hydroxy-vitamin D [25(OH) vitamin D] in patients with GTN and normal pregnant women.

Methods: In this prospective case-control study, 30 GTN patients and 48 normal pregnant women were considered as control group who referred to Qaem University Hospital, Mashhad, Iran, from July 2013 to October 2015 were included. All included persons to the study had no history of chemotherapy or using vitamin D supplements. After filling informed consent forms and recording demographic data, 25(OH) vitamin D serum level were measured in both group by enzyme-linked immunosorbent assay (ELISA) method.

Results: Age in two groups was the same (P=0.565). There was no significant difference in gestational age between two groups (P=0.887). Pathologic diagnosis in 83.33% (25 patients) was complete hydatidiform mole and in 16.67% (5 patients) was partial hydatidiform mole. 25(OH) vitamin D serum level in 73.3% of GTN patients and 2.1% of normal pregnant women was lower than 10 ng/ml and among all participants, only 6.3% of pregnant patients had 25(OH) vitamin D serum level higher than 30 ng/ml. Mean serum level of 25(OH) vitamin D in GTN patients was significantly lower than pregnant women group (9.09±5.46 vs. 20.06±6.37, P=0.000). 25(OH) vitamin D serum level between complete and partial hydatidiform mole groups had no significant difference (P=0.384).

Conclusion: Altogether, it was observed that 25(OH) vitamin D serum level is significantly lower in women with GTN than normal pregnant women. Modifying serum levels of vitamin D in molar pregnancy with low level of vitamin D may prevent the development of GTN.

Abstract

Background: Surgical staging is the standard treatment of ovarian cancer. Pelvic and para-aortic lymphadenectomy is the important part of the surgery. The aim of this study was to evaluate the effect of para aortic lymph node dissection in early stage of patients with ovarian cancer.

Methods: This descriptive cross-sectional cohort study was performed on all stage I of ovarian cancer patients admitted in department of gynecology oncology of Ghaem Hospital, Mashhad University of Medical Sciences in November 2012 to March 2014. Every patient with clinical early stage of ovarian cancer candidate to surgical treatment selected. All cases underwent surgical staging surgery with concurrent systematic pelvic and para-aortic lymphadenectomy. In laparotomy after identification of left and right iliac artery, all lymph nodes have been properly exposed and dissected as a part of a staging laparotomy. The dissection was continued up to the nodal tissues surrounding the aorta, and inferior vena cava, until inferior mesenteric artery lymphadenectomy level. The procedure performed only by gynecologist oncologist. In addition, we assessed other parameters such as operation time, estimated blood loss, associated mortality and morbidity and vascular injuries. Finally, the effect of para aortic lymph node dissection in early stage of ovarian cancer evaluated.

Results: Among a total of 57 ovarian cancer patients, 27 of them apparent stage I disease cases were selected. Surgical staging surgery with concurrent systematic pelvic and para-aortic lymphadenectomy was carried for all of them. Positive para-aortic lymph node was found only in one case. The average number removed para-aortic lymph nodes in the pelvis was 9 and in para aortic was 7, respectively. In addition, 20 minutes increase in total length of operation time was observed duo to para-aortic lymphadenectomy. Also the rate increase in intra-abdominal hemorrhage rate was estimated 60 ml.

Conclusion: Lymph node dissection will produce a significant benefit in accurate and complete surgical staging. Staging surgery in addition to systematic pelvic and para aortic lymph adenoctomy in early stage ovarian cancer is preferred in gynecologic oncology centers.

Volume 75, Issue 2 (May 2017)
Abstract

Background: Postoperative pain is one of the most common complications following laparoscopic cholecystectomy. Because the majority of the analgesic drugs including opioids and nonsteroidal anti-inflammatory drugs have many side effects, using drugs with lesser side effects is beneficial. The aim of this study was to evaluate the effect of N-acetylcysteine on the pain after laparoscopic cholecystectomy.

Methods: In a randomized clinical trial, in two university-affiliated teaching hospitals in Babol City (Shahid Beheshti and Shahid Yahyanezhad Hospitals), Iran, from August 2015 to March 2015, a total number of 38 patients with age of 20-50 years, who were candidates for laparoscopic cholecystectomy with American Society of Anesthesiologists Class-I were chosen and randomly assigned into two groups. The night before operation, 1200 mg oral N-acetylcysteine is given to intervention group. Also, they received 600 mg IV N-acetylcysteine in the morning before operation. In the control group, two vitamin C effervescent tablets as placebo were given at night before operation and 3 ml sterile water as placebo was injected in the morning of operation. Amount of pethidine consumption and the changes in hemodynamic in two groups was recorded and analyzed at 24 hours after operation.

Results: The average of patients age was not significant different between two groups (P=0.23). Average of pain score in placebo group was 3.5 and in N-acetylcysteine group was 2.7 that it was not significant difference between two groups (P=0.06). Average of pethidine consumption in placebo group was 52 mg and in N-acetylcysteine group was 29 mg in 24 hours, that the difference was statistically significant between two groups (P=0.01)

Conclusion: As the results of the study, it can be concluded that the anti-inflammatory effects N- acetylcysteine can inhibit the function of lipoproteins and prostaglandins, reduced glutathione peroxidase and dismutase has been restored and can be used to treat pain or analgesic dose reduction. In this study the N-acetylcysteine  has reduced  pain after laparoscopy and analgesic dose of mepridine.

Volume 75, Issue 5 (August 2017)
Abstract
Background: Breast cancer is the most common cancer in women and can have several profound effects on women’s life. Estrogen and androgens reduction cause sexual problems. Reduction of hormones produce problems such as vaginal dryness, vaginal and vulvar tissue thinning, loss of elasticity of the vagina, hot flashes and other problems. Depression in these patients is also a factor in reducing sexuality. Disruption at any sexual stage can cause sexual problems. In this article; we compare sexual dysfunction in patients with breast cancer and healthy people.
Methods: According to the women’s case-control study with simple un-randomized sampling method a total of 245 patients with breast cancer in Ghaem and Emam Reza and Omid hospital from july 2011 to july 2013 entered the study. All patients were on follow-up after therapy, and had a therapy portfolio. In order to achieve better results, questionnaires were distributed among 126 healthy subjects that matched our patient group in terms of age and other factors and were used as the control group. Female sexual function index (FSFI) questionnaire was filled out by an independent interviewer and all medical, personal and social ethics were applied. The data was then gathered and the score were analyzed with statistical tests.
Results: The study was performed on patients 20 to 50 years, mainly in patients aged 35 to 45 years (51.8%). The average age was 41.44±5.87 years. In our study, the most dysfunction was in sexual desire (57.6%), vaginal moisture (53.1%), sexual excitement (48.2%), orgasm (44.1%), and dyspareunia (52.2%) in breast cancer patients. There was significant difference between two group (P<0.001).There is no difference about sexual satisfaction between two groups (P=0.262).
Conclusion: Sexual dysfunction is common in breast cancer patients compared to healthy women. Dysfunction in orgasm, dyspareunia, reducing vaginal moisture and sexual desire were common in the breast cancer patient. The results of this study should be used to inform patients and physician about sexual problems.

Volume 75, Issue 8 (November 2017)
Abstract
Background: The causes of Attention-deficit/hyperactivity disorder (ADHD) (the most common psychological disorder is still unknown. The main symptoms include impulsivity, hyperactivity and attention deficit. Some studies have shown the relationship between ADHD and oxidative stress, and yet some researches have shown the effects on vitamin D on the antioxidants level. This research intends to identify the effect of vitamin D supplementation on the antioxidant serum level in 6-13 years old children with ADHD.
Methods: This double blind clinical trial was conducted in Isfahan city, the center of Iran, from October 2015 to February 2016. The sample included 35 subjects of both groups that were randomly selected among 6-13 years old children with ADHD diagnosed by pediatric psychologist. The intervention group consumed 1000 IU of vitamin D3 daily for three months, and the control group used placebo for the same period of time. Their stature and weight were recorded by digital instruments without the shoes with the least clothes. The next step was to train the food record of the students to the parents so that 3 food records were taken during the study. 25-hydroxyvitamin D3 (25(OH)D3), TAC (Total antioxidant capacity), MDA (Malondialdehyde), CAT (Catalase) and GSH (Glutathione) of the participants of both groups were measured before and after the intervention.
Results: In this Study, both groups were adjusted in terms of their age, gender and BMI. The mean score of the variables of leisure time and sport showed no significant difference in the both groups. Comparing the average TAC and MDA between the two groups before intervention didn’t show a significant difference (P1TAC=0.06) (P1MDA=0.32), but after the intervention, the vitamin D intake group showed the increase in TAC and decrease in MDA (P2TAC=0.001) (P2 MDA=0.01). Moreover, CAT and GSH showed no significant difference in the two groups before and after intervention.
Conclusion: Vitamin D supplementation for 3 months led to the improvement of antioxidant capacity by the increase of TAC and decrease of MDA, but the CAT and GSH showed no significant change in the mentioned period of time.

Malihe Hasanzadeh , Mina Baradaran Khalkhale , Akram Behroznea, Leila Musavi ,
Volume 75, Issue 12 (March 2018)
Abstract
Background: Graves' disease is the most common cause (85% of all cases) of thyrotoxicosis in women in childbearing age. Many of the symptoms are similar to hyper-metabolic status during pregnancy. The cause of the disease is autoantibodies that stimulate the thyroid-stimulating hormone (TSH) receptor. Hyperthyroidism is uncommon in pregnancy and its prevalence is 0.1-%0.4. In this paper we introduce a patient who was admitted with a primary diagnosis of pulmonary embolism and treatment with final diagnosis of thyroid storm and was discharged with good condition.
Case presentation: In the first pregnancy of a 29-year-old woman with gestation age of 31 weeks was referred to obstetric emergency unit Ghaem Hospital, Mashhad, Iran in March 2015. She had Grave’s disease in her past medical history which was treated with methimazole before pregnancy and propylthiouracil (PTU) during pregnancy. In admission, she presented with tachycardia and tachypnea and hypertension and lower extremity edema. During pregnancy, she used propantheline instead of propylthiouracil due to pharmacy mistake. She admitted in Intensive care unit. After rule out of pulmonary embolism, ultrasonography showed a fetus with 30 weeks of gestational age with an approximate weight of 1680 grams. The amniotic fluid was reduced. She was treated with thyroid storm diagnosis due to a medication error. In serial obstetric visits fetal heart rate was not detected. Due to the fetal death, the pregnancy was terminated. Hyperthyroid therapy continued with PTU after delivery. She was discharged with a good general condition.
Conclusion: Despite the rarity of thyroid storm during pregnancy, in the event of unstable hemodynamic condition and cardiac dysfunction in pregnant women, rule out of thyroid disorders should be considered. Clinician should be paid attention to past drug history and underline disease of patient.

Volume 76, Issue 5 (August 2018)
Abstract
Background: Cancer of the endometrium is the most common gynecologic malignancy in western and industrial countries, and is the second most common in developing countries, therefore it is of special importance. Adenocarcinoma of the endometrium is the most common type of uterine cancer. The prevalence of endometrial cancer in young women under the age of 40 in western country is very low and about 5 percent. The aim of this study was to determine the prevalence of endometrial cancer at age ≤40 years in our center during 4 years.
Methods: In a cross-sectional study, all medical records of patients with endometrial cancer in Ghaem University Hospital, Mashhad, Iran was reviewed to identify women <40 years of age with endometrial cancer, over the course of 4 years, (from 2012 to 2015). The risk factors for endometrial cancer, such as obesity, polycystic ovary syndrome (PCO), infertility, and a history of cancer in the family or individual, were collected in each patient. Clinical features, histological type of endometrial carcinoma, and therapeutic action also were gathered.
Results: A total of 119 patients with endometrial cancer that was admitted in our genecology oncology center were evaluated. 19 patients (15.9%) were younger than 40 years old. 16 cases (84.2%) with endometrial adenocarcinoma and 3 (15.7%) had endometrial stromal sarcoma. The youngest patient was 27 years old and the oldest was 39 years. Seven patients (8/36%) had infertility and we don’t know about fertility condition in 3, because they were single. 12 cases (63%) were overweight (BMI≥35) and 6 cases (5/31%) had polycystic ovarian disease (PCOD). In 2 patients, there was concomitant ovarian and endometrial cancer. Histology report of both ovaries was endometrioid and both patients were overweight. Obesity, poly cystic ovary syndrome (PCOD) and Infertility were the most important risk factors for endometrial cancer in young patients.
Conclusion: The prevalence of endometrial cancer in young women under the age of 40 in our country is so higher than the statistics provided in industrial countries.

Volume 76, Issue 9 (December 2018)
Abstract
Background: Escherichia coli (E. coli) is one of the most important infectious agents in patients undergoing prostate biopsy. It belongs to a large family of gram-negative rods, Enterobacteriaceae. This family includes members of the normal flora of the intestine that are only occasionally pathogenic. Recent considerations of rectal colonization with fluoroquinolone-resistant E. coli shows the need to change strategy of treatment of infection in patients undergoing prostate biopsy. Therefore, the purpose of this study was to determine molecular typing of fluoroquinolone resistant (FQR) E. coli rectal isolates and associated infections in patients undergoing prostate biopsy.
Methods: In this prospective cohort study, rectal swabs were collected from 158 male patients before prostate biopsy at the Urology Research Center of Sina Hospital, Tehran, Iran, from March 2015 to February 2016. The FQR organisms were isolated using selective media, and antibiotic susceptibility pattern was determined for following antibiotics, ampicillin, levofloxacin, cotrimoxazole, amoxicillin-clavulanate, cefazolin, ceftazidime, cefepime, gentamicin, piperacillin-tazobactam, nitrofurantoin, amikacin, fosfomycin, imipenem. In general, phylogenetic background, prevalence of E. coli sequence type 131 (ST131) and its subclones (H30 and H30-Rx ST131) were compared in two groups of FQR E. coli rectal colonization and clinical isolates.
Results: In total, 73 patients had a positive rectal culture for FQR gram-negative bacteria, the most prevalent isolate of which was E. coli. Phylogenetic group B2 was most predominant, followed by A, E, C and D, B1 and F. The antibiotic susceptibility patterns for the FQR organisms showed high levels of resistance to ampicillin and trimethoprim-sulfamethoxazole, while the resistance to amikacin, fosfomycin and imipenem remained very low. In general, antibiotic resistance to several antibiotic was mainly detected in group B2 and with ST131 genotype. Despite the increase in infections among patients colonized with strains of E. coli ST131, its frequency was almost statistically significant between colonized and infected groups.
Conclusion: The ST131 pathogen has a high prevalence in rectal colonization and post prostate biopsy infections, which showed widespread resistance to common antibiotics.

Malihe Hasanzadeh, Lida Jedde , Leila Mousavi Seresht , Khatereh Vatanpoor ,
Volume 76, Issue 9 (December 2018)
Abstract
Background: Twin pregnancy consist a healthy fetus, and hydatidium molar pregnancy is unusual and very rare. Its incidence is in about 1,22,000 to 1,100,000 of all pregnancies. This type of pregnancy is commonly associated with several obstetric complications requiring early termination of pregnancy. Managing a twin mole pregnancy with normal and live fetuses is controversial, although this unusual type of abnormalities in most cases leads to abortion or intrauterine fetal death. In other hand, due to the high probability of obstetric complications during pregnancy, such as preeclampsia in 25% of cases, metabolic complications such as hyperthyroidism and vaginal bleeding pregnancy is terminated. Survival of the normal coexisting fetus is variable and depends on whether the diagnosis is made, and if so, whether problems from the molar component. Present study reported a case of coexisting mole and live fetus twin pregnancy with successful outcome.
Case presentation: A 35 years old woman, G2ab1 which was diagnosed to have twin pregnancy with mole and coexisting live fetus in 11 weeks of gestational age was referred to obstetric department of Ghaem Hospital, Mashhad University of Medical Sciences, Iran in January 2017. Close follow-up and obstetric surveillance had performed for her and at the last her pregnancy was terminated in gestational age of 36 weeks; a healthy male infant. The β-human chorionic gonadotrophin (BhCG) levels still is undetectable after one year.
Conclusion: Twin pregnancy with one normal fetus and a co-existing molar pregnancy could be continued under close surveillance if the live fetus has normal karyotypes and no structural anomaly and decreasing level of serum BhCG level during the time. Close monitoring necessary even after termination due to increasing risk of persistence trophoblastic disease after termination, what was performed in this case also.

Cervical Cavernous hemangioma in a patient with postcoital bleeding: case report
Malihe Hasanzadeh, Raheleh Ebrahimi, Parnian Malakuti,
Volume 78, Issue 11 (February 2021)
Abstract
Background: Cervical cavernous hemangioma is an extremely rare, benign lesions, and only a few cases are reported. Cervical cavernous Hemangiomas are characterized by an increase in the number of normal and abnormal veins. The majority of these lesions are superficial, often found in the head and neck area, but may also occur in the inner parts of the body. The occurrence of these lesions in the female reproductive tract, especially the the cervix is extremely rare. This disease should be considered as a differential diagnosis of abnormal uterine bleeding because of the low prevalence and importance of the diagnosis of this uncommon disease. The majority of cervical cavernous hemangiomas have been reported in women of childbearing age. Besides, although most lesions are symptomatic (mostly bleeding), diagnosis is often unlikely. They may cause abnormal vaginal bleeding in the form of menometrorrhagia and postcoital spotting. To date, fewer than 55 cases have been reported. This study aimed to report a rare case of cervical cavernous hemangioma.
Case Report: The patient was a 24-year-old woman who had referred to the outpatient clinic of Ghaem Hospital in September 2016 due to prolonged post coital bleeding after intercourse. At the time of the pelvic examination, posterior lip of cervix was very vascular and there was black color that had extend to the vagina. The patient underwent colposcopy. Following colposcopy, due to severe cervical bleeding, the vagina packed. The patient's bleeding was controlled with the pack after 24 hours. Cervical pathology revealed a cavernous hemangioma.
Conclusion: Cervical cavernous hemangioma is extremely rare. This should be considered in the differential diagnosis of patients with abnormal vaginal bleeding, especially those of childbearing age, and no clinical or radiologic findings such as leiomyoma, adenomyosis, or dysfunctional uterine bleeding. Pelvic examination is the first step in the management of the patient with vaginal bleeding. Increased awareness of this unusual cervical lesion can lead to early diagnosis and conservative treatment approaches. In most cases, hysterectomy is performed, but the patient with mild symptoms can be treated with conservative management. Increased awareness of this unusual cervical lesion can lead to early diagnosis and conservative treatment approaches.

Volume 79, Issue 1 (April 2021)
Abstract
Background: The Extensor Carpi Radialis Longus (ECRL) and the Extensor Carpi Radialis Brevis (ECRB) are muscles of the posterior forearm compartment. variations in this area of the forearm are common and are usually diagnosed during surgery. Sometimes these variations are symptomatic and can be helpful in clinical procedures such as surgery. Diagnosis and identification of abnormalities can be used in academic studies to evaluate limb function. Reporting such variations is important in clinical practice and will help treat limb dysfunction. In this report, we report two cases of ECRL and ECRB muscle tendon variations in the upper third of the forearm.
Case presentation: During routine dissection of the body of a 70-year-old man fixed in 10% formalin in the Department of Biology and Anatomy, Shahid Beheshti University of Medical Sciences, Tehran, two cases of ECRL and ECRB muscle tendon variations were observed in the upper third of the left forearm. The fascia of the ECRL and ECRB muscles were separated, and following the ECRL muscle from the external epicondyle of the humerus to the outer third of the forearm, we observed that the tendon of this muscle was divided into two branches. We also observed that the ECRB muscle tendon split into two branches slightly below its origin. The branch had moved obliquely toward the lower end of the radius. at the lower end of the forearm, this tendon was connected to the ECRL muscle tendon by passing over the sub-branch of the ECRL muscle tendon and the depth of the retinaculum extensor. The submandibular tendon was attached to the base of the second Metacarpal bone along with the ECRL muscle tendon. The main branch of this muscle also had its main path to the lower end of the forearm. The lower end of the forearm was connected to the dorsal base of the second and third metacarpals by passing under the retinaculum extensor.
Conclusion: Knowing these variations can help radiologists and surgeons in diagnosis and treatment.

Abstract
Today surgery is supposed as the cure for many diseases and the fear of post-operation pain burdens stress over the patients. Postoperative pain can, especially if severe, complicate the patient's condition and may lead to chronic postoperative pain. post-operation pain control is effective in the recovery process, hospitalization period and patients’ satisfaction. Insufficient post-operation pain control increases complications and care costs. Local analgesia is one of the components of multimodal postoperative. analgesic protocol to control pain. Local analgesia technique is a simple, accessible and feasible method for various surgeries. The opioid analgesics to control post-operation pain are associated with some complications such as opium addiction, nausea and vomiting, late return of bowel function and social costs. This review study aims. to review previous studies on the effect of injection of analgesic agents in the surgical incision in post-operation pain control. This is a Narrative review study. to related scientific documentaries a search was conducted in Persian and English using the keywords of local injection of the incision site, wound infiltration with analgesic agents and post-operation pain control in Google scholar, PubMed and Scopus database during the years 2000 to 2020. The obtained articles included systematic reviews, Meta-analyses and randomized clinical trials (RCT). We reviewed studies that had utilized single-dose injection of analgesic agents in surgical incisions at the end of surgery to control post-operation pain. A total of ten studies were reviewed. There were 4 studies in the field of laparoscopic gynecological and non-gynecological surgeries, three studies in the field of laparotomy and three review studies. injection of analgesic agents in the surgical incision to control post-operation pain is easily available and does not necessitate any special skill. On the other hand, it is a safe method without further complications and does not increase the duration of surgery. Regardless of the differences in various studies and the kind of analgesic agents, a general reduction in pain severity and consumption of opioid and non-opioid analgesic agents were observed using the injection of analgesic agents in surgical site incision.

Abstract
Background: Aggressive angiomyxoma is a rare mesenchymal tumor with extensive local invasion. It often presents with a lump in the perineal area and pelvic. Since it often does not involve adjacent organs such as the urethra and anus, does not cause obstructive symptoms. Its incidence is 6 times higher in women than men. This tumor grows slowly and has a slight tendency to metastasize. However, the rate of local recurrence is high. MRI is the most widely used diagnostic method. Ultrasound and CT scan are also used for diagnosis. Due to the rarity of this tumor, it is difficult to diagnose before surgery and pathology assessment. Due to the penetrating nature of the tumor and the lack of a clear capsule, incomplete surgical resection is common. Local recurrence is common even after complete mass resection. Therefore, patients need a long follow-up. The main treatment is surgery but non-surgical interventions such as hormonal therapy, radiotherapy, arterial embolization, etc. have been associated with variable success rates.
Case Presentation: A 54-year-old female patient presented with a vulvar mass in February 2021. The patient mentioned that the mass had existed for ten years and had increased in size in the last two years. After discussion on the tumor board, she underwent surgery. The pathology of the mass was reported to be aggressive angiomyxoma. The patient was treated with a GNRH agonist after surgery. The patient is currently under follow-up and has not had a recurrence so far (March 2020).
Conclusion: Aggressive angiomyxoma is a rare mesenchymal tumor. It has extensive local invasion and a high recurrence rate, but distant metastasis is rare. Estrogen receptors or Progesterone receptors are commonly positive in aggressive angiomyxoma. The best treatment for aggressive angiomyxoma remains unknown. Extensive local resection of the tumor has been reported as an important therapeutic measure. In cases of mass recurrence, reoperation and hormone therapy have been effective. It is important for gynecologists to consider this tumor as a differential diagnosis when dealing with vulvar masses.

Abstract
Background: Breast cancer is the most common type of cancer in many countries, accounting for over 18% of all cancers in females. There are more than one million new cases of breast cancer each year. Most women diagnosed with breast cancer are over the age of 50, but younger women can also get breast cancer. About one in seven women are diagnosed with breast cancer during their lifetime. There's a good chance of recovery if it's detected at an early stage. In Iran, breast cancer is the most common cancer among women, making up 21.4% of all female cancers. The mortality rate of this cancer is 4.33 for every 100,000 people. The purpose of this research is to see how often different kinds of early breast cancer come back and how long people live after being diagnosed.
Methods: This retrospective study evaluated the medical records of 500 breast cancer patients at two hospitals in Mashhad, Iran during April 2006 to March 2016. We used SPSS software, version 16 (SPSS Inc., Chicago, IL, USA) to analyze data. A P value less than 0.05 means that the results are considered statistically significant.
Results: We included 230 women with breast cancer. The average overall survival was 130.7 months, with 83.2% of people surviving for five years and 78.8% surviving for 10 years. The stage of the disease is strongly linked to the recurrence (P=0.000). Additionally, the specific type of disease is also strongly related to disease recurrence (P=0.01) or metastasis (P=0.01). Patients who have the triple-negative subtype had the highest chance of the cancer spreading and recurrence compared to patients with other subtypes.
Conclusion: The different types of breast cancer are strongly linked to the disease recurrence or metastasis. Patients with triple-negative subtypes had the most cases of cancer spreading to other parts of the body and coming back again, compared to other subtypes. Our findings also showed that patients with the triple-negative disease had the worst overall and disease-free survivals.
