Amenorrhea is the absence or abnormal cessation of menstrual cycles in a woman of reproductive age. Prolonged cessation of menstrual cycles might results in complications such as infertility, psychosocial developmental delays, Osteoporosis, fractures etc. Better understanding of physiology of menstruation is essential to understand the various causes of primary and secondary amenorrhea. Any disruption or functional abnormality in the hypothalamic-pituitary-ovarian axis can result in abnormal menstruation or amenorrhea. Therefore it is crucial to identify this menstrual distress in women at early age to minimize the risks of reproductive dysfunction in premenstrual and postmenstrual conditions.

Environmental electromagnetic fields are nowadays available in all environments today. These areas affect the biological system. Controlled interactions with elecrtomagnetic fields can have positive effects when unrestricted interactions have negative effects. Uncontrolled exposure to low-frequency electromagnetic fields can cause adverse effects such as signal transduction in cells and tissues, cell membrane structure, ion channels, molecular interactions, DNA damage. But contrary to controlled exposure, it positively affects tissues. The most obvious example of this is seen in the bone and cartilaginous tissue. Repairing fractures and damage in bone and cartilage. This has been shown in many studies. Below is a summary of the relevant information.

The success of vaginal birth after cesarean section (VBAC) has been correlated with a variety of maternal characteristics such as age, ethnicity, and body mass index (BMI, calculated as weight in kilograms divided by height in meters squared). The patient’s BMI just prior to delivery has been shown to be a better prognostic indicator of success than pre-pregnancy BMI. Gestational weight gain was previously associated with a decreased rate of successful VBAC. More recent research has not supported such an association. The objective of our study was to further validate these findings with a larger population. We performed a retrospective cohort study of women undergoing trial of labor after cesarean (TOLAC) at our institution from January 2010 to December 2019. Women were divided into three groups based on weight gain in pregnancy as compared to the American College of Obstetrics and Gynecology (ACOG) recommendations (i.e. < 25 pounds (lbs), 25-35 lbs, > 35 lbs). We further subdivided the pregnancies between term and preterm deliveries. The primary outcome was a successful VBAC. Of 1087 patients attempting a TOLAC, 772 (71%) were successful and 315 (29%) failed VBAC. When grouped according to ACOG weight gain recommendations, 303 (31%) women were below ACOG guidelines, 318 (33%) met guidelines, and 339 (35%) exceeded guidelines. There was no difference in the rate of VBAC success among the three groups. When counseling patients, providers should still promote healthy dietary habits but should not correlate excess weight gain with chance of TOLAC success.

Background: We have developed a femoral supporting pad with an integrated ultrasound probe holder and examined its practical usability on patients with lower limb surgery. Objectives: To evaluate the function of this novel femoral supporting pad with respect to its practicability during the performance of a distal sciatic nerve blockade, the time needed to perform this blockade including the catheter insertion and the quality of postoperative analgesia within the first 24 hours. Methods: 50 patients which had been scheduled for elective lower leg, ankle or foot surgery had received a continuous blockade of the distal sciatic nerve. Sciatic nerve blockade was performed sonographically controlled with the patients in supine position by using our novel femoral supporting pad with an integrated ultrasound probe holder. Primary endpoint: duration of the intervention. Secondary endpoints: pain intensity (visual analogue scale VAS 0-10) at the first postoperative day; cumulative opioid (piritramide) requirement during their stay on the post Anaesthesia care unit (PACU) with vs. without distal sciatic nerve blockade. Results: 49/50 patients received a distal sciatic catheter, which had been sonographically placed within a mean time (mean ± sd) of 11:30 ± 3:13 minutes. VAS at the first postoperative day was (mean ± sd) 1 ± 2 at rest and 2 ± 2 as maximum. The piritramide requirement during PACU stay (mean ± sd) was 11 ± 8 mg without vs. 3 ± 6 mg with distal sciatic nerve blockade (p< 0.05). Conclusion: Continuous distal sciatic nerve blockade using a novel femoral supporting pad with an integrated ultrasound probe holder was feasible in 49 of 50 patients within 11 minutes and 30 seconds.

The Czech model for reducing maternal and neonatal mortality for countries in sub-Saharan East Africa was created on the basis of the Archdiocesan Charity Prague project for a specific region-subcounty Buikwe, Diocese of Lugazi, Mukono Region in Uganda, a region with about 30,000 inhabitants. The aim of the first phase of the project was to build a new hospital, equip it completely for obstetric and surgical operations from the Czech Republic, ensure its activities with Czech and Slovak doctors experts, junior Ugandan doctors and Ugandan medical staff, provide obstetric training for villagers, ensure connections with villages and possibility of fast transport and urgent solution of all acute pathologies in the hospital, capable of 24-hour surgical readiness. In the second phase of the project, a school for midwifery was to be established. This second part of the project has not yet been implemented. The project could serve as an example and guide for similar humanitarian activities in other regions of Uganda and other countries in equatorial Africa.

Ischemic heart disease may occur in isolation, or in combination with the pathological process of vascular ageing, arteriosclerosis. These two conditions have differing impacts on the haemodynamic changes in response to anaesthesia and surgery. Hypertension is not a feature of ischemic heart disease, and vice versa, but where the two conditions co-exist, hypertension aggravates and accelerates the pathological processes of ischemic heart disease. Patients older than 40 yrs. presenting for anaesthesia and surgery must therefore be considered at risk of any combination of these three conditions. Anaesthetic techniques must also be chosen to minimize haemodynamic changes which in the normal healthy patient cause no serious morbidity, but which, in the patient with ischemic heart disease, can lead to serious morbidity or death. Here we report a 70 years old (BMI of 23.3) elderly, hypertensive Male patient with ischemic heart disease with previous MI (EF of 40% - 5%) undergoing elective Inguinal hernia repair. We Opted Spinal anesthesia over General anaesthesia as it should be an asset in cardiac patients undergoing non-cardiac lower abdominal surgeries to reduce preload and after load, stress response, coagulation responses, improves coronary perfusion, provides better postoperative analgesia, reduces incidence of perioperative MI, maintains myocardial oxygen supply demand ratio and avoids harmful effects of GA such as hypotention due to intravenous induction drugs, tachycardia and hypertension due to pressor response during direct laryngoscopy and tracheal intubation.

Background: Neonatal Near-miss is defined as complications of neonates so severe as to be imminently life-threatening but survived due to chance or treatment. The number of neonates who survived morbidities were approximately 3 to 6 times greater than those who died. There was little evidence about neonatal near miss in Ethiopia. This study attempted to identify the determinants of neonatal near miss among neonates admitted to the Ambo University Referral Hospital and Ambo General Hospital. Methods: Hospital-based quantitative unmatched case-control study was conducted at the Ambo University Referral Hospital and Ambo General Hospital from March 1 to 28, 2019. The respondents, 134 cases and 268 controls were recruited by simple random technique. Data were coded, entered and cleaned in EpiInfo version 7 and exported to SPSS. Both Bivariable and multivariable logistic regression was computed at 95% CI and the final model was checked by Hosmer and Lemeshow goodness -of-fit test. Multi collinearity and cofounders were not detected. Result: Multivariate analysis showed that distance more than 15km away from health facilities [AOR=2.11, 95% CI: (1.09, 4.095)], Unwanted, and unplanned current pregnancy [AOR=3.71, 95% CI: (1.28, 10.79)], less than four Antenatal care visit [AOR=6.55, 95% CI: (3.07, 13.98)], Instrumental delivery [AOR=4.62, 95% CI: (1.78, 11.98)] were positively associated with Neonatal Near Miss. Whereas Term Neonates [AOR= 87%, 95% CI: (0.05, 0.32)], and Normal birth weight [AOR=91%, 95% CI: (0.03, 0.28)] were negatively associated with Neonatal Near Miss. Conclusion: Distance from health facilities, Antenatal care visit, current pregnancy type, birth weight, gestational age and mode of delivery were determinants of Neonatal Near Miss. Therefore, providing adequate Antenatal services, health education and training is needed to improve neonatal health.

The choice of the optimal muscle relaxant in one-day surgery in children with “small” surgical interventions remains relevant to this day. In modern pediatric surgery, the requirements for the quality of muscle relaxation are highest. However, along with the effectiveness of the drug, its duration and controllability of the action, as well as the safety of use, are important [1-7]. The aim of the study: To determine the pharmacoeconomic rationale for the rational use of muscle relaxants, depending on the duration of operations in one-day surgery in children. Material and research methods: The study was conducted in surgical clinics of the Azerbaijan Medical University. The study included 156 children who were operated on routinely from 0 to 16 years old (risk of anesthesia I-II ASA), who used combined endotracheal anesthesia during surgery. Based on the requirements of the GCP international program (Good Clinical Practice), the inclusion of children in the study was carried out only after the written consent of the parents. The studied patients were divided into 3 groups depending on the muscle relaxant used: IA (n = 52) - rocuronium bromide (esmeron), IB (n = 52) - atracurium besilate (tracrium), IC (n = 52) - cisatracurius besilate (nimbex). Depending on the type of general anesthesia, these groups were also divided into 2 subgroups: anesthesia based on isoflurane + fentanyl ″ + iso ″ and anesthesia based on sevoflurane + fentanyl ″ + sev ″. The main groups were also divided into 2 age subgroups: children under 2 years of age – IA1, IB1, IC1 and children from 2 to 16 years old – IA2, IB2, IC2.

Introduction: Chronic low back pain is one of the most prevalent musculoskeletal disorders. Studies have shown certain relations between physical fitness and chronic low back pain (CLBP) by examine some measures of physical fitness. The aim of study was to measure lung function using winspiro PRO in patient with CLBP versus normal healthy individual, and relation of lung function with duration and intensity of CLBP. Methodology: The study population is comprised of a total of 120 adult persons. 60 subjects with chronic low back pain (41 male and 19 female) with a mean age of 30.69 years (+4.34) and 60 normal individual (39 male and 21 female) with mean age of 29.00 years (+5.34). Results:The result of comparison of the respiratory parameter forced vital capacity (FVC), and maximal voluntary ventilation (MVV) of individual with CLBP show a significant difference as compare to the normal healthy population. In unrelated ‘t’ test the patient with CLBP (N=60) of age 30.51(SD±4.33), height 169cm (SD±1.23), weight 57.86(SD±7.73) and body mass index (BMI) 20.46 (SD±2.54) show a significant difference in respiratory parameter FVC ( t=17.244, P=0.000), and MVV ( t=11.048, P=0.000) as compare to the normal healthy persons (N=60) of age 29.79 (SD±5.28), height 170cm (SD±1.13), weight 59.40(SD±6.97) and BMI 21.59 (SD±3.29).In patient group- FVC range is 34.0% to 75.00% (52.85%±9.30). MVV range is 45.0% to 86.80%. (63.11%±12.06)In control group FVC range is 63.90% to 98.83% (83.63%±7.59). MVV range is 63.00% to 98.00% (78.96%±7.86). Conclusions:The overall result of the study show that there is a significant difference in the respiratory parameter that is FVC (forced vital capacity), and the MVV (maximum voluntary ventilation) in persons with chronic low back pain as compare to the healthy person of same age, height, weight and body mass index (BMI).

In various patients conditions involved in lower urinary tract disease LUT (like overactive bladder, bladder neck sclerosis, dis –synergy (with our synenrgic contraction between bladder detrusor and bladder neck, BPH, recurrent cysytitis, interstitial cystitis, chronic prostatitis, uretral stenosys, loss of sfinteric coordination. Prostatic cancer, anatomic abnormalities and other the receptor status play relevant role to reduce effect of vicious clycle that can be responsible in progression of the pathologic process. In this work the complex receptorial status is analyzed to verify new therapeutic strategies. Starting from the observation that various irritant substanties produce irritant stimulus in Prostatic Patients or in bladder neck condition is interesting to deep understand the etio-patogenesys and Functional results. In Various prostatic, bladder neck or ureteral condition a reduced urinary fluss can produce infectious. Conditions like acute or chronic prostatitis. Irritants sustanties in diet (in example etilic alcohol drink, hot spices, crud meats, carbonate drinks, caffeine and other) can produce Painful stimulus in innervations of vecical trigonous, bladder neck and prostatic urethra. The same recurrent cystitis and Bph contribute in a complex situation. This stimulus produce ipertonus of bladder muscle involved in the expulsion of urine. The event related inflamation and edema (bladder, prostatic uretra, trigonus) contribute to the global effect. So conditions like bladder neck sclerosys IPB, recurrent prostatitis and cistitys in acts in a vicious circle. (Also immunomediated: Bph and cronic prostatitis with linfocite infiltration and tissue remodeling). The ormonal status check the systems (see 5-ARI efficacy in Bph). Simpatic, parasimpatic and other system are deeply involved. Also behavioral habits or diet can influence in example urinary flux in a complex system like LUT. (Bladder and prostatic irritants that can produce edema and acute inflamation). Other behavior habits are deeply involved as too much sedentary, water intake, coffee, pee modality and also psychological profile and stressing conditions. Some disease like diabetes produce high consequences in all this systems due to Bladder modification, oxidative stress, osmotic movens, and increase susceptibility of urinary infections. This article are verified this kind of movens that contribute in physio -pathology of some low urinary tract conditions. The anatomic abnormalities produces, obviously, physiological disfuntions. Recurrent urinary tract infections, inadequate antimicrobial therapy: Profile of resistance, duration of therapy, kind of antimicrobials, posology, Pk. Kinetics, associations, compliance, biofilms, micro calcifications (recurrent chronic prostatitis) contribute to a progression of the condition.

Objectives: Our main objectives are to reveal the pregnancy and neonatal impacts of COVID-19 infection and to compare it to the results that are reported in the literature. Methods and materials: The characteristics of the admitted pregnant patients COVID-19 positive with their initial presentation, course at the hospital, and short term follow-up are exposed. Correlation of the age and gestational age with the severity of the disease was calculated. Results: Thirty five COVID-19 positive pregnant patients presented between the beginning of March and the end of April 2020. From 5 weeks till 41 weeks of gestation, all trimesters were included. The mean of age is 32 and the BMI equal 28.2. Associated comorbidities included not only diabetes and hypertension but also PCOS. The symptomatology was considered mild in most of the cases. The distribution of the symptoms included cough in 86%. 10 out of 35 delivered and cesarean was performed in 50% of the cases. The mean length of stay is 6 days. Neither maternal nor neonatal deaths occurred. There is a significant correlation between the age of the patient and the severity of the disease but this is not the case with gestational age. Conclusion: Our results were comparable to the literature in terms of initial presentation, associated comorbidities and the length of stay. Despite the fact that the cesarean rate was high, it was far below that of the literature. More data is still needed about COVID-19 in pregnancy.

Bone metastases in cancer patients are highly painful and decrease the quality of life for these group of population. Covid-19 pandemia is a global challenging issue that mostly affect the patients with immune suppression or having comorbid diseases older than 65 years old. The palliation and management of bone metastases varies from single dose to several fractionation. The main goal of this article is to decide that short or long term fit for the cancer patients with bone metastasis in the Covid-19 era. We reviewed the topic about the short course and long term radiotherapy in the patients with painful bone metastases via novel literature.

Background: Telerehabilitation has been identified as an effective treatment that promotes exercise rehabilitation in individuals with multiple sclerosis (MS). Social support is recognised as a core element of such interventions. However further research is needed to consider the role and value of different social support domains. Aim: Review available literature to assess and synthesise the use and value of social support within telerehabilitation interventions for individuals with MS. Method: A narrative synthesis was conducted. A systematic search of included articles was conducted. Electronic databases were searched from inception to January 2017. Other search methods were undertaken. Evaluation and synthesis of included articles utilised risk of bias assessment and a 4-stage synthesis process. Main Results: A total of fourteen studies, involving 718 participants (505 female, 213 male; aggregated mean age 47.6 years) with MS, were included. Esteem support was the most frequently reported method of social support, followed by informational, emotional and tangible. It would appear social support can be beneficial in assisting participants to adhere to treatment interventions. Visual feedback may be directly beneficial to improve impaired balance in individuals with MS. A model for future interventions is provided. Conclusions: Social support appears to increase the adherence of participants with MS to telerehabilitation interventions. Unique findings provide an indication for the direction and content of future interventions. Further research is necessary to ascertain the optimal types and frequencies of social support delivery and its effect on health outcomes for participants with MS.

The study was conducted in Ilu and Waliso districs of South West Shoa Zone to investigate the perception of dairy cattle producers on oestrus synchronization and mass artificial insemination services. A total of 122 respondents (38 from Ilu and 84 from Waliso districts) owning at least one lactating cow and participated in synchronization program were randomly selected and interviewed individually by using semi- structured questionnaire. Both primary and secondary data were used to generate reliable information on the intended topic. All collected data were analyzed using SPSS statistical package version 20 and the output was presented by descriptive statistics such as percentage and mean values in inform of graphs. Most of the respondents (67.15%) indicated that their satisfaction level towards synchronization and mass artificial insemination was low. Only few of them reported being satisfied as (medium-13.45%, good - 12.35% and very good - 7.05%). This might be because of shortage of feed, silent heat, poor performance of the inseminator and low awareness of farmers on the technology. From the study it was also noted that the overall percentage (26.22%) of calving rate to oestrus synchronization and mass artificial insemination was low. This might be due to heat detection problem (36%); A.I technician efficiency (29.25%), absence of A.I technician (23.9%) and distance of A.I center (10.25%). Therefore, the skill and knowledge based training should be given for both the farmers and implementers to enhance perception and adoption of the technology.

Anal melanoma is a rare and highly aggressive mucosal melanocytic malignancy. It is the third most common after melanomas of the skin and retina. The peak incidence in seen in the sixth and seventh decades. The clinical symptoms are pain, anal mass, bleeding per rectum, tenesmus or change in the bowel habits. It affects anal canal, rectum or both with a tendency to spread along submucosal planes. It is mostly beyond complete resection at the time of diagnosis and majority of patients die of metastasis. MR imaging significantly increases the diagnosis of anal melanoma in its early stages.

Introduction: Candidiasis is more frequent in human immunodeficiency virus (HIV)-infected patients and knowledge about the distribution and antifungal susceptibility of oral Candida species is important for effective management of candidiasis. Material and Methods: An oral rinses sample collected from hundred HIV-infected patients with and without clinical evidence of oral candidiasis in this study at the Infectious Department/Tripoli Medical Center, Libya. Species identified by standard phenotypic and conventional methods and in vitro susceptibility testing of the yeast isolates to antifungals were performed using the Disc diffusion method protocol as recommended by the Clinical Laboratory Scientific Institute. Results: Oral Candida colonization is detected in all patients with and without clinical syndromes, and Candida albicans were accounted for (74%), C. dubliniensis (11%) and C. glabrata (6%). A high proportion of Candida species (42%) showed decreased susceptibility to fluconazole. Among C., albicans more than 30% of isolate were resistant to most new azole antifungal including fluconazole, itraconazole, posoconazole and voriconazole. Conclusions: A significant number of oral Candida species particular Candida albicans exhibiting decreased susceptibility to fluconazole were isolated from colonized HIV-infected individual, given the high incidence and severity of fungal infections in HIV-infected individuals. The results of this study reinforce the importance of antifungal susceptibility testing, which contributes to the therapeutic strategies and highlights the need for continuous surveillance of Candida colonization in this population.

Background: Proximal humerus fractures (PHFs) are common injuries particularly in older adults. Evidence-based protocols for PHF rehabilitation are lacking and physiotherapists use a variety of interventions. Purpose: To determine practice patterns and perceptions of physiotherapists who treat adults with PHF in Ontario, Canada. Method: A paper and pencil survey asking about respondent demographics and management of Neer Group 1 (minimally/nondisplaced) and complex (displaced 3- and 4-part) PHF was mailed to 875 randomly selected physiotherapists who were registered with the College of Physiotherapists of Ontario in 2013/2014 and working in practice areas likely to be accessed by adults with PHF. Results: The response rate was low (10%); 83 physiotherapists completed the survey - 80% had experience managing PHF. Respondents treated 1-5 individuals with PHF annually; more treated Neer Group 1 PHF (89%) than complex PHF (68%). Most individuals with PHF were older than 60 years (64%), female (76%) and accessed physiotherapy through a doctor’s referral (91%) more than 1 month post injury (33%). Main findings: Physiotherapists manage PHF using multi-component interventions and a minimum of 76% include the following elements: education and progression of passive, active assisted, active range of motion exercises and muscle retraining to build coordination and strength. Use of other elements was variable. The main factors influencing the treatment plan were the ability of the individual with PHF to comply, bone quality, and fracture type. Most respondents were unsure that there is sufficient PHF rehabilitation literature to guide treatment. Conclusions:This environmental scan is the first North American study to document practice patterns and attitudes of physiotherapists providing PHF rehabilitation. Elements used by physiotherapists in Ontario treating small numbers of individuals with Neer Group 1 or complex PHFs each year align well with the limited PHF rehabilitation literature available. Potential implications:Multi-disciplinary collaborations to design and conduct large, high quality, multi-centre prognostic studies and RCTs that evaluate the effectiveness of key aspects of non-surgical PHF rehabilitation in various patient groups are needed. Meanwhile, consensus guidelines should be developed in the context of region-specific physiotherapy service models to inform best practice in PHF rehabilitation management.

Breast cancer is the most common cancer in women and is a major public health problem. It is divided into several subtypes, including triple negatives. The general objective of our study is to establish the profile and the management of patients with triple negative breast cancer over a period of 2 years, operated in our department. During our study period, triple-negative breast cancers accounted for 10% of our population. The most affected age group ranges from 50 to 60. The majority of patients in our sample are pauciparous. In the group of patients who received hormone therapy, it was mainly HRT for 4 to 6 years. 96.77% of patients consulted a health worker within 3 months of the discovery of the signs. Adenopathies are frequently present at the time of diagnosis. 93.54% of the cases have an invasive ductal carcinoma. Triple negative cancers are essentially poorly differentiated. Triple-negative cancer has a high rate of cell renewal. In our study, neoadjuvant chemotherapy is mostly indicated for triple-negative breast cancers ≥ 30 mm at diagnosis and a delayed lumpectomy is then performed in 23.52% of the patients. For tumors of < 30 mm size, a lumpectomy is performed immediately in 76.47% of the patients, followed by adjuvant chemotherapy. Mastectomy was performed in 45.16% of patients; it was mainly indicated in front of a large tumor size associated with a small breast volume, then multifocal breast tumors. Breast reconstruction was performed in 21.42%. Radiation therapy is indicated in the majority of patients, postoperatively. In our population, 11 patients were proposed to have an oncogenetic survey; it was mainly indicated based on the Manchester criteria in front of a young age and a family history of cancer. There are two BRCA 1 mutations, one BRCA 2 mutation, and one case of absence of mutation. The therapeutic intake in case of a mutation is directed towards a prophylactic bilateral mastectomy and adnexectomy, proposed at the age of 40. Two patients had presented triple negative recurrences of their already treated breast cancer; first case PDL1 positive PD-L1 ≥ 1% treated with immunotherapy combined with chemotherapy (atezolizumab/abraxane) while the second and second PDL1 negative treated with chemotherapy alone. Despite their low frequency, triple negative breast cancers represent a subgroup marked by pejorative characteristics, a reserved prognosis, with limited treatment options.

Nonsurgical fertility control is increasingly advocated as more cost-effective than surgical sterilization to manage stray animal populations in a different part of the world. An experimental study was conducted from December 2018 to April 2019 at Mekelle University to evaluate the effect of single bilateral intratesticular injection of cetrimide 2% in adult albino mice. A total of 20 clinically healthy albino mice selected based on their age and sex and were divided randomly into five groups and evaluation was conducted for 30 days after intratesticular injection of cetrimide solution 2% at the dose rate of 5, 10, 15 and 20 mg per testis and for control 0.1 mL normal saline per testis per 100 g body weight were given. All albino mice were evaluated for 30 days at a fixed interval. Change in body weight, scrotal width, sexual behavior, and fertility performance was also assessed. On day 30, all albino mice were sacrificed for histopathological study. Means  ±  Standard deviation of the mean, one-way, and a mixed model ANOVA (for repeated measures) was used to summarize the data, determine the effects of group and time on bodyweight and scrotal width. The significant increase in body weight (p - 0.001) and significant reduction of scrotal width (p - 0.001) were noted in all cetrimide treated in comparison to control groups. In addition, there was a significant (p < 0.05) reduction of scrotal width in albino mice after intratesticular injection of cetrimide on day 1, 10, 15, 20, 25, and 30 with respect to their experimental groups. Testicular histology revealed that there were multinucleated giant cells in seminiferous tubules, derangement of tubular architecture along with infiltration of leucocytes and appearance of fibrous tissue were seen on testicular sections at a dose rate of 15 and 20 mg. Similarly, a significant change in the sexual behavior of the treated males and no pregnancy was detected on female albino mice after 21 days post-coital at 10, 15, or 20 mg cetrimide-treated males. In conclusion, a single bilateral intratesticular injection of cetrimide 2% at a dose of 15 and 20 mg might provide an effective way of sterilization and may be considered as an alternative to surgical castration in male animals. Besides, further assessment should be done in the future to identify the mechanism of infertility.

Objective: To identify the risk factors for marginal cord insertion (MCI). Material and Methods: This case-control study was carried out between 1st February and 30th June 2019. Singletons with and without MCI at delivery were recruited. Main variables analyzed included maternal age, parity, number of previous dilatation and curettage (D&C) or manual vacuum aspiration (MVA), time interval between each procedure and conception, cord insertion. Fisher’s exact test, t-test and logistic regression were used to compare data from both groups. Results: We found 60 cases of MCI (4.1%). The significant (p < 0.05) risk factors for MCI were past-history of D&C (aOR 5.97, 95% CI 1.95-18.25) particularly when conception occurred ˂ 5 months after D&C (OR 10.5, 95% CI 1.36-81.05), fetal female sex (aOR 3.82, 95% CI 1.41-10.32), parity ≥ 4 (aOR 2.63, 95% CI 1.05-12.71) and past-history of MVA (aOR 2.06, 95% CI 1.23-8.76). Conclusion: Women should be advised to conceive at least five months after D&C.
