Rupture of the gravid uterus in a tertiary health facility in the Niger delta region of Nigeria: A 5-year review

Background:

Ruptured uterus is a major life-threatening condition encountered mostly in developing countries and is an index of failure of obstetric care at a point in time in a woman''s reproductive career. With worsening economic condition, increasing caesarean section rates, and patients’ aversion for operative delivery this condition would still remain a major obstetric matter for discussion.

Objective:

To identify the incidence, sociodemographic variables, clinical characteristics, causes, and outcome of ruptured uterus at the University of Port Harcourt Teaching Hospital.

Materials and Methods:

A 5-year retrospective study of cases of ruptured uterus at the University of Port Harcourt Teaching Hospital was carried out. The case notes of 40 patients with uterine rupture during the period 2003-2007 were analyzed. Data collected included sociodemographic characteristics, etiologic factors, clinical presentation, and outcome. Data were analyzed using Microsoft Excel version 2007 and SPSS 14.0 computer software.

Results:

The incidence of rupture of the gravid uterus was 1:258 deliveries. In patients with rupture of the gravid uterus, 65% (26) of patients were unbooked; 37.5% (15) were aged between 25 and 29 years. A total of 42.5% (17) of patients had secondary education and 21 (52.5%) were housewives. Rupture of a previous scar was the commonest etiologic factor accounting for 32.5% (11). The commonest presentation was abdominal pain in 92.5% of cases. Perinatal mortality and maternal mortality were 80% and 17.5% respectively.

Conclusion:

Rupture of the gravid uterus still remains a major cause of maternal mortality. Injudicious use of oxytocics should be discouraged in peripheral health facilities and reinforcement of the need for hospital based deliveries in patients with previous caesarean sections should also be intensified to improve outcome.     

Admission cardiotocography: Its role in predicting foetal outcome in high-risk obstetric patients

Background

Routine and continuous electronic monitoring of foetal heart rate (FHR) in labour has become an established obstetric practice in high-risk pregnancies in industrialised countries. However, the same may not be possible in non-industrialised countries where antenatal care is inadequate with a large number of high-risk pregnancies being delivered in crowded settings and inadequate health care provider to patient ratios.

Aims

The objective of this study was to evaluate the predictive value of the admission cardiotocogram (CTG) in detecting foetal hypoxia at the time of admission in labour and to correlate the results of the admission CTG with the perinatal outcome in high-risk obstetric cases.

Method

This was a prospective observational study conducted in the labour and maternity ward of a hospital in Gangtok, India, during the period 2008 to 2010. The study included high-risk pregnant women, admitted via the emergency or outpatient department with a period of gestation ≥36 weeks, in first stage of labour with foetus in the cephalic presentation. All women were subjected to an admission CTG, which included a 20 minute recording of FHR and uterine contractions.

Results

One hundred and sixty patients were recruited. The majority of women were primigravida in the 21-30 years age group. About 42% patients were postdated pregnancy followed by pregnancy-induced hypertension (PIH) (15.6%) and premature rupture of membranes (PROM) (11.3%) as the major risk factors. The admission CTG were ‘reactive’ in 77%, ‘equivocal’ in 14.4% and ‘ominous’ in 8.7% women. Incidence of foetal distress, moderate-thick meconium stained liquor and neonatal intensive care unit (NICU) admission was significantly more frequent among patients with ominous test results compared with equivocal or reactive test results on admission. Incidence of vaginal delivery was more common when the test was reactive.

Conclusion

The admission CTG appears to be a simple non-invasive test that can serve as a screening tool in ‘triaging’ foetuses of high-risk obstetric patients in non-industrialised countries with a heavy workload and limited resources.     

Obstetric Outcomes in Chinese Women with Endometriosis: A Retrospective Cohort Study

Background:

The effect of endometriosis on obstetric outcomes is still ambiguous. The aim of our study was to determine the association between endometriosis and adverse obstetric outcomes in a cohort of Chinese women.

Methods:

A retrospective cohort study was undertaken to compare obstetric outcomes between 249 women with endometriosis and 249 women without endometriosis. All women were nulliparous and achieved singleton pregnancies naturally. Women with endometriosis were diagnosed during surgery and confirmed histologically. Odds ratios (ORs) and 95% confidence intervals (CIs) of measures of obstetric outcomes were calculated.

Results:

Women with endometriosis showed significantly increased risks of preterm labor (adjusted OR, 2.42; 95% CI, 1.05–5.57), placenta previa (adjusted OR, 4.51; 95% CI, 1.23–16.50), and cesarean section (adjusted OR, 1.93; 95% CI, 1.31–2.84). No significant differences were observed in the incidence of pregnancy-induced hypertension, fetal growth restriction, small for gestational age, placental abruption, or luteal support in the first trimester between the two groups.

Conclusions:

Women with endometriosis are at a higher risk of preterm labor, placenta previa, and cesarean section during pregnancy and need additional care.     

Clinical Analyses of 66 Cases of Mid-trimester Pregnancy Termination in Women with Prior Cesarean

Background:

The rate of cesarean delivery has significantly increased in China in the last decade. Women with prior cesarean history tend to have a higher risk of uterine rupture during termination of the pregnancy in mid-trimester than those without such a history. The aim of our study was to evaluate the influences of the potential risk factors on uterine rupture in women with prior cesarean.

Methods:

We conducted this retrospective study of women with prior cesarean section, who underwent mid-trimester pregnancy termination between January 2006 and December 2013 in Peking Union Medical College Hospital. The protocol was oral administration of mifepristone and misoprostol for the patients with the gestational ages below 16 weeks or intra-amniotic injection of ethacridine lactate (EL) for those with at least 16 weeks of gestational ages. The thickness of the lower uterine segment (LUS) was measured before the termination of pregnancy. Logistic regression was used to study the risk factors of uterine rupture.

Results:

The total rate of successful abortion was 93.9% (62/66). Four patients failed in induction, and one of them received curettage, whereas the other three experienced uterine rupture (4.5%). The successful rates of abortion were 85.7% (30/35) for women treated with mifepristone-misoprostol and 86.1% (31/36) for those treated with EL. There was a significant difference in the mean LUS thickness between the uterine rupture group (3.0 ± 2.0 mm) and the nonrupture group (7.0 ± 3.0 mm) (P < 0.05). The LUS thickness of <3 mm was associated with uterine rupture during mid-trimester pregnancy termination in women with prior cesarean (odds ratio, 94.0; 95% confidence interval 4.2–2106.1) after adjusted maternal age, gestational age, interdelivery interval and prior cesarean section. Severe bleeding that required transfusion occurred in one case (1.5%).

Conclusions:

Both the mifepristone-misoprostol and the EL regimens were effective and safe for the termination of mid-trimester pregnancy in women with prior cesarean. A thinner LUS is associated with a relatively high risk of uterine rupture.     

Is vaginal delivery safe after previous lower segment caesarean section in developing country?

Background:

To analyse the mode of delivery in trial of labour (TOL), incidence of successful vaginal deliveries and indications of repeat caesarean section (CS).

Materials and Methods:

Prospective selective study. Study population consisted of 367 pregnant women with previous one lower segment caesarean section (LSCS) in reproductive age group. These were grouped in to three groups, Group 1 (n = 239): Women, who were elected for repeat CS without a TOL. Group 2 (n = 76): Women, who were given TOL and delivered vaginally. Group 3 (n = 52): Women, who were given a TOL but due to failed trial, had to be taken for emergency repeat section. The maternal and foetal outcome was studied in all the groups.

Statistical Method Used:

The data was entered in the Microsoft excel worksheet, values expressed as mean ± SD. Chi-square test was done to compare the categorical variables among the groups. ANOVA (one-way analysis of variance) was done to compare the baseline characteristics of patients and time to delivery among the groups.

Results:

Out of 128 women who were given TOL, 76 (59.37%) vaginal birth after caesarean (VBAC) occurred, out of which 40 (52.63%) had spontaneous vaginal deliveries without augmentation of labour and 36 (47.36%) subjects had augmentation of labour with artificial rupture of membranes (ARMs) and oxytocin. A total of 52 women (40.62%) underwent emergency LSCS.

Conclusion:

Proper selection and counselling about clinically significant risks, women can be given TOL with careful monitoring and taken for emergency LSCS on minimal indication is the best answer to management of previous one CS in labour.     

The benefit of myomectomy in women aged 40 years and above: Experience in an urban teaching hospital in Nigeria

Background:

Abdominal myomectomy remains the mainstay of surgical management of uterine fibroids in our environment. However, its benefit in women aged 40 years and above remains debatable.

Materials and Methods:

An 11-year prospective study was conducted involving 98 women, aged 40 years and above, who had abdominal myomectomy for the treatment of uterine fibroid at the University of Maiduguri Teaching Hospital, Maiduguri. They were followed up regularly for 1–6 years to detect conception, resolution of symptoms and obstetrics performance. Data were analyzed using SPSS version 13.

Results:

The mean age of the patients was 42.6±2.9 years and 77 (78.6%) of them were nulliparous. Lower abdominal swelling was the commonest clinical presentation and the mean uterine size was 18.6±8.5 weeks. Infertility with uterine fibroids was the indication for myomectomy in majority of the cases [48 (48.9%)], while pregnancy complications accounted for 11.2% (11) of the cases Fertility restoration was 10.4% among the infertile patients. There was complete resolution of symptoms in 35.9% of those who required symptomatic relief, and term pregnancies were recorded in 72.7% of patients with pregnancy complications.

Conclusion:

Myomectomy is the recommended treatment of uterine fibroids in women aged 40 years and above with infertility and who wish to become pregnant. If there is no need for further fertility preservation, hysterectomy should be offered.     

Pain perception among parturients at a University Teaching Hospital,South-Western Nigeria

Introduction:

Labour pain is a universal experience. Relief of labour pains and companionship in labour are important aspects of quality of care in labour.

Objectives:

To evaluate perception of labour pains among parturients, their knowledge and awareness of pain relief during labour, the types of obstetric analgesia available and the outcome of their labour at the Ekiti State University Teaching Hospital, Ado-Ekiti.

Materials and Methods:

A cross-sectional study using questionnaire administered to pregnant women between 37 and 42 weeks gestational age in labour ward of the hospital.

Results:

The study revealed that 75.2% of the parturients experienced severe labour pains and 35.3% of them received analgesia in labour with Pentazocine injection being the only analgesic used. Only 18.3% had maximum relief of their pains. Parturients with increasing parity, higher social class and educational attainment and who had antenatal education on labour pains were associated with severe perception of labour pains with P values of 0.03, 0.03, 0.02 and 0.01, respectively. Parturients who were given Pentazocine injection for pains and had relief in labour had more spontaneous vaginal deliveries, P = 0.030 and better outcome for their babies, P = 0.028. Majority of the women reported that the practice of companionship and back rubbing in labour helped them to cope better with the labour process.

Conclusion:

Most women desire relief of pains of labour but the practice is still suboptimal in this centre. Efforts should be made towards developing the practice of obstetric analgesia and companionship in labour in this environment.     

Perinatal mortality audit at Tikure Anbessa Teaching Hospital,Addis Ababa,Ethiopia: 1995 to 1996

Objectives

To determine the prevalence and causes of perinatal mortality rates at Tikure Anbessa hospital, Ethiopia, 1995–96

Design

A cross-sectional review of hospital records of all women who delivered at Tikure Anbessa Hospital. Data were collected prospectively.

Setting

Teaching Hospital of Tikure Anbessa, Addis Ababa, Ethiopia

Subjects

Women and neonates from 8986 deliveries. Deliveries exceeding 28 weeks of gestation or birth weight of 1000 grams were considered.

Materials and Methods

All deliveries were included for infants whose gestational age exceeded 28 completed weeks. When the gestational age was unknown, the birth weight of 1000 grams or more was considered. All perinatal deaths and obstetric complications were identified. Labour chart, mode of delivery and summary of delivery had been recorded by the responsible resident at a monthly combined obstetric and paediatric perinatal mortality meeting. Age of the mother, parity, booking status for antenatal care, obstetric complications, labour, mode of delivery, birth weight, gestational age, one and five minutes Apgar scores were collected.

Results

A total of 8986 deliveries were conducted during the study period. Of these 6933 (77.2%) were booked for antenatal care while the remaining 2053 (22.8%) were not booked in any health institution. The perinatal mortality rate of the hospital was 71.6 per 1000 live births. The risk of perinatal mortality was more than doubled among mothers who failed to book for antenatal care follow-up and no laboratory investigations was done were birth asphyxia followed by premature birth 15.4% and 12% respectively.

Conclusions

Perinatal mortality rates are high at Tikure Anbessa Hospital, Ethiopia. There is need to ensure that pregnant women are booked for antenatal care so as to provide adequate antenatal and perinatal health care.     

A study evaluating the effect of mifepristone (RU-486) for the treatment of leiomyomata uteri

Background:

To estimate the efficacy of daily administration of 25 mg mifepristone for the treatment of uterine leiomyoma.

Materials and Methods:

A total of 30 women were to receive 25 mg mifepristone daily for a period of 6 months. Abdominal ultrasonography was performed before treatment, at 3 months and after 6 months, to evaluate the leiomyoma size and uterine volume. Endometrial biopsy was done after the treatment. Efficacy was estimated by the reduction in leiomyoma size, uterine volume, and improvement in quality of life.

Results:

After 180 days of treatment, there was a 47% decrease in the leiomyoma volume and a 53% decrease in the uterine volume. Symptomatic improvement was noted. Twenty-three of 30 women (75.7%) became amenorrheic after the treatment. Endometrial biopsy after treatment revealed simple hyperplasia in two of 30 women.

Conclusion:

25 mg mifepristone produces reduction in leiomyoma size and uterine volume and produces symptomatic improvement in women with fibroids.     

Intensive care management and outcome of women with hypertensive diseases of pregnancy

Introduction:

The burden of hypertensive diseases on the health care is enormous given to the high population in Sub-Saharan Africa and related disproportionate representation in global maternal mortality.

Materials and Methods:

All women with hypertensive diseases of pregnancy who got admitted into the general ICU of the University of Benin Teaching Hospital between January 2006 and December 2010 were studied. Only the records of women who completed 28 weeks of gestation and were admitted during labour and delivery or puerperium to the ICU were examined.

Results:

There were 13061 deliveries within the 5-year study period; 9301 by vaginal delivery and 3860 through Caesarean section. 52 (51.5%) of the obstetric patients had hypertensive diseases of pregnancy. Of 52 women with pre-eclampsia and eclampsia, 45/52 had caesarean section and 7/52 had SVD. Admission was mainly postpartum 48/52 (92.3%). 35/52 (67.3%) were transferred to the ward and 17 died (32.7%), giving the ICU maternal mortality rate of 307/1000 deliveries. 30 women developed pulmonary oedema alone or with renal impairment; 14 women were transferred and 16 died while 21 other patients who had renal impairment alone, HELLP, sepsis, etc were transferred out. There was about a 12-fold risk of death in the unit if the patient developed pulmonary oedema when compared to the other factors combined (p = 0.0002, RR = 11.7, 95%CI = 1.7 – 82.).

Conclusion:

Primiparity, unbooked status and caesarean delivery were leading factors for ICU admission in women with preeclampsia/eclampsia. The women who developed pulmonary oedema in the course of treatment had poor outcome and avoidance of pulmonary oedema may improve ICU outcome in women with preeclampsia/eclampsia.     

Reappraisal of twinning: epidemiology and outcome in the early neonatal period

INTRODUCTION

The present study aimed to determine the epidemiology, maternal complications and adverse neonatal outcomes associated with twin births at a tertiary care hospital in India.

METHODS

A prospective observational study was conducted on all successively born twin pairs (≥ 23 weeks of gestation) and their mothers from January to September 2005. Main outcome measures included maternal medical/obstetric complications, labour characteristics and the morbidities/mortality observed during the early neonatal period.

RESULTS

The twinning rate was 1 in 54 deliveries. Around 10% of mothers had a predisposition for twinning in the form of familial tendency or consumption of clomiphene. Anaemia (85%) was the most common maternal complication, followed by gestational hypertension (17%). Nearly one-third of births were delivered via Caesarean section. Prematurity (61%) was the most common neonatal complication followed by early-onset neonatal sepsis (21%). The risk of early neonatal death was 27%. Shorter gestation and low birth weight were significantly associated with adverse neonatal outcome (p < 0.05). Factors such as chorionicity, mode of delivery, birth order, inter-twin delivery time interval, gender and intra-pair birth weight discordance did not affect neonatal morbidity or mortality (p ≥ 0.05).

CONCLUSION

The rates of maternal complications and early neonatal morbidities/mortality were quite high in twin gestations. Except for the prematurity and low birth weight, none of the other factors, including inter-twin delivery time interval of more than 15 mins, were found to affect neonatal outcome.     

Bad Obstetric History: A Prospective Study

Background

Death of an infant in utero or at birth has always been a devastating experience for the mother and of concern in clinical practice. Perinatal mortality remains a challenge in the care of pregnant women worldwide, particularly for those who had history of adverse outcome in previous pregnancies. To assess the risk factors and outcome of pregnancies in cases of bad obstetric history (BOH) and compare the results with control group, this study was undertaken.

Methods

A prospective study from 2003 to 2007 was carried out in 79 pregnancies having BOH (history of unexplained stillbirth/neonatal death, three or more consecutive abortions etc). Test group was analyzed in terms of age, gravida, parity, risk factors and outcome in terms of preterm delivery, stillbirth, mode of delivery, birth weight, pregnancy complications and fetal distress. These parameters were compared with a systematic, randomly selected sample from rest of the deliveries. Necessary advice and treatment was given in cases of hypothyroidism, hypertension, antiphospholipid antibody (APLA) syndrome, gestational diabetes and other risk factors.

Result

There was significantly higher incidence of malpresentations, hypertension, APLA, cervical incompetence, preterm deliveries and caesarean section in test group (p< 0.05). In this study, only 47 (59.49%) women out of 79 in BOH group were identified to have possible factor responsible for pregnancy losses. In 32 (40.51%), no probable causes could be identified. Nine (11.39%) patients were identified with more than one risk factor.

Conclusion

APLA, hypertension, malpresentation, cervical incompetence, preterm deliveries and caesarean section were found significantly more in BOH group. In a large percentage of pregnancies with BOH, the risk factors for adverse outcome were not identified but pregnancy outcome was generally good in subsequent pregnancies with optimal antenatal care and advice.Key Words: Bad obstetric history, Antiphospholipid antibody syndrome, Gestational diabetes, Stillbirth     

Management of intractable postpartum haemorrhage in a tertiary center: A 5-year experience

Background:

The purpose of this study is to describe treatment alternatives to prevent postpartum hysterectomy after failure of conventional therapies. Prevention of hysterectomy was the main outcome studied.

Materials and Methods:

This is a retrospective study of 19 patients diagnosed to have intractable postpartum hemorrhage and not managed with medical treatment who were subsequently treated with operative interventions in our unit between January 2004 and January 2009. The cases were identified by review of medical records.

Results:

In the period under review, a total of 17,341 deliveries were conducted, out of which 19 women were managed for intractable PPH. The incidence of severe PPH unresponsive to standard medical treatment was 0.1%. The mean maternal age was 33.5±3.4 years (range 27–39 years). The mean gestational age was 38.3±1.3 weeks (range 37–41 weeks). Organ preserving surgery methods were utilized in all the patients with a success rate 78.9%. The mean duration of surgery was 95 minutes (range 50–130 minutes) and the mean hospital stay was for 5 days. The mean transfused blood volume was 2.4 units as packed red cells. Among these 19 cases, 4 cases were resorted to hysterectomy.

Conclusions:

In the presence of uncontrolled hemorrhage, this simple procedure should be tried before other complex treatment alternatives are undertaken. Our case series suggests that the combination of uterine artery ligation with B-Lynch sutures might be the best surgical approach because it preserves future fertility better than other methods and avoids high operative risks and morbidity.     

Maternal Factors for Low Birth Weight Babies

Background

Low birth weight is defined as the live births with less than 2.5 kg weight. It is a key determinant of infant survival, health and development. Low birth weight infants are at a greater risk of having a disability and for diseases such as cerebral palsy, visual problems, learning disabilities and respiratory problems. To reduce the low birth weight deliveries, we studied the maternal factors which adversely affect the fetus in utero and their impact on fetus.

Methods

A retrospective study was carried out on 40 low birth weight pregnancies out of 650 deliveries from July 2005 to Jun 2006. Maternal factors like age, parity, pre pregnancy body mass index, hemoglobin levels, bad obstetric history (history of stillbirth/neonatal death in previous pregnancies, three or more spontaneous consecutive abortions), pre eclampsia, fetal distress, mode of deliveries were studied. These results were compared with a random sample of 300 pregnant ladies taken from rest of the deliveries. Cases of multiple pregnancies and stillbirths were excluded.

Result

We found that prepregnancy maternal body mass index (p<0.01 for BMI <20), unbooked status (p<0.01), pre eclampsia (p <0.01) and bad obstetric history (p<0.01) were the maternal factors which resulted in low birth weight babies in most of the cases. However in 10 (25%) cases, no contributory maternal factor was found.

Conclusion

Prepregnancy maternal body mass index, unbooked status, pre eclampsia and bad obstetric history are significant maternal factors resulting in low birth weight babies.Key Words: Prepregnancy maternal body mass index, Unbooked status, Pre eclampsia, Bad obstetric history     

A Marked Increase in Obstetric Hysterectomy for Placenta Accreta

Background:

Obstetric hysterectomy (OH) as a lifesaving measure to manage uncontrolled uterine hemorrhage appears to be increasing recently. The objective of this study was to determine the etiology and changing trends of OH and to identify those at particular risk of OH to enhance the early involvement of multidisciplinary intensive care.

Methods:

A retrospective study was carried out in patients who had OH in China-Japan Friendship Hospital from 2004 to 2014. Maternal characteristics, preoperative evaluation, operative reports, and prenatal outcomes were studied in detail.

Results:

There were 19 cases of OH among a total of 18,838 deliveries. Comparing the study periods between 2004–2010 and 2011–2014, OH increased from 0.8/1000 (10/12,890) to 1.5/1000 (9/5948). Indications for OH have changed significantly during this study period with uterine atony decreasing from 50.0% (5/10) to 11.1% (1/9) (P < 0.05), and placenta accreta as the indication for OH has increased significantly from 20.0% (2/10) to 77.8% (7/9) (P < 0.05). Ultrasonography and magnetic resonance imaging (MRI) have been used to make an exact antepartum diagnosis of placenta accreta. A multidisciplinary management led to improved outcomes for patients with placenta accreta.

Conclusion:

As the multiple cesarean delivery rates have risen, there has been a dramatic increase in OH for placenta accreta. An advance antenatal diagnosis of ultrasonography, and MRI, and a multidisciplinary teamwork can maximize patients’ safety and outcome.     

Elective caesarean section in a tertiary hospital in Sokoto, north western Nigeria

Background:

Elective caesarean sections have been considered safer for both mother and the fetus compared to their emergency counterpart. However, emergency caesarean sections have continued to form bulk of caesarean deliveries in our facility.

Objective:

The objective of this study was to determine the caesarean section rate together with the trend, indications, and maternal mortality associated with elective caesarean operation.

Materials and Methods:

A retrospective analysis of clinical records of all the patients that had caesarean section between January 2002 and December 2010 (9 years) at Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto, Nigeria was conducted.

Results:

During the 9 year study period, 2284 caesarean sections were performed out of 22,985 total deliveries at UDUTH Sokoto, thus giving a caesarean section rate of 9.9%. Emergency and elective operations accounted for 1784 (78.2%) and 498 (21.8%) of the cases respectively. The rate of elective caesarean section increased from 1.7% in 2002 to 3.2% in 2007. Thereafter it declined gradually to 1.8% in 2010. Repeat caesarean section (30.7%) and malpresentation (17.1%) were the most common indications for elective caesarean operation. There were 18 maternal deaths from caesarean section and only one from the elective caesarean procedure.

Conclusion:

The rising trend in the elective caesarean section rate in this study underscores the need for better and improved patient selection together with counseling on its benefits and risks. This is because despite the fact that it is safer than emergency caesarean operation, it is not entirely devoid of complications. Routine use of spinal anesthesia in performing the procedure should be encouraged.     

Prospective Study of Saline Infusion Sonography and Office Hysteroscopy

Background

To evaluate the diagnostic potential of saline infusion sonography to pick up uterine cavity lesions and compare it with the gold standard office hysteroscopy.

Methods

Study population consisted of women scheduled for office hysteroscopy for various indications. Uterine cavity of 208 women of the study group were evaluated first by saline infusion sonography and then by office hysteroscopy by two separate examiners. Findings were recorded separately for both procedures and compared. Pain rating was also noted after each procedure. Result: In eight patients either or both the procedures could not be performed for various reasons, hence were excluded from the analysis. With saline infusion sonography, pathological findings were identified in 93 (46.5%) patients and hysteroscopy detected lesions in 88 (44%) patients. For all findings combined sensitivity of saline infusion sonography was 90.9%, specificity 88.3%, positive predictive value 86.0% and negative predictive value 92.5% as compared to hysteroscopy. Former was less painful and easier to perform than the latter.

Conclusion

The findings of saline infusion sonography and office hysteroscopy did not differ significantly. Thus saline infusion sonography is an excellent option for uterine cavity evaluation.Key Words: Hysteroscopy, Saline infusion sonography, Uterine cavity abnormality     

Uterine sarcoma: Clinico-pathological characteristics and outcome

Objectives:

To investigate the clinical and histopathological characteristics, with the prognostic factors, treatment outcome, pattern of relapse, and survival analysis of uterine sarcoma patient

Methods:

All patients with histologically proven uterine sarcoma were identified using the database at King Abdulaziz University Hospital, Jeddah, Saudi Arabia between January 2000 and December 2012.

Results:

A total of 36 patients with uterine sarcoma were reviewed. The median age of all patients was 57 years, and the mean age was 57.72±13.17 years. Carcinosarcoma was reported in 21 patients (58%), leiomyosarcoma in 7 (19%), undifferentiated endometrial sarcoma in 6 (17%), and rhabdomyosarcoma in 2 (6%). Approximately half of the patients were stages III and IV (28% and 25%), while 15 patients (41%) were stage I; only 2 patients (6%) were stage II. The surgical treatment was hysterectomy and bilateral salpingoophorectomy (H+BSO) plus staging in 18 patients (50%), while in 4 patients (19%), H+BSO plus debulking was performed. Adjuvant chemotherapy was given in 24 (69%) and adjuvant radiotherapy in 5 (14%) cases, At a median follow-up period of 13.5 months, 8 patients (22%) relapsed. The 2-year disease-free survival (DFS) rate was 22% and the 5-year was 14%. In the multivariate analysis, the advanced stages (p=0.015) and lymph vascular invasion (p=0.0001) were associated with poor DFS, while the use of chemotherapy significantly improved the DFS (p=0.027).

Conclusions:

The poor outcome of high-grade uterine sarcoma patients was identified, and only one third of patients (30%) survived for 2 years. This finding necessitates the need for more aggressive tools to fight this disease.Uterine sarcomas are rare tumors that account for 1-3% of all female genital tract malignancies and 3-8% of all uterine malignancies.1-3 This heterogeneous group of tumors originates from uterine mesodermal tissue. The major uterine sarcomas consist of leiomyosarcoma (LMS) and endometrial stromal tumors (EST), the latter of which are sub-classified into 3 categories by the World Health Organization (WHO): endometrial stromal nodules (ESNs), endometrial stromal sarcoma (ESS, historically referred to as low-grade sarcoma), and undifferentiated endometrial sarcoma (UES, historically called high-grade sarcoma). Carcinosarcoma, previously called malignant mixed mullerian tumor, is considered a deviant of carcinoma, and its behavior, and treatment resembles those of high-grade carcinoma. However, there are still some centers that treat this as sarcoma.4 Uterine sarcomas occur primarily in women who are 40-60 years old.5,6 A history of pelvic irradiation was also considered a risk factor in 5-10% of cases.7 Compared with the more common types of endometrial cancer, women with uterine sarcoma have a poor prognosis due to the aggressiveness of the disease.5-7 The most frequent prognostic factors include the stage, histological subtype, grade, lymph vascular invasion, and menopausal status.8-10 Standard treatment of early stage patients are hysterectomy and surgical staging, and approximately half of these patients develop recurrent disease.10 Post-operative radiotherapy reduces local recurrence and improves local disease but does not affect the overall survival.11,12 Adjuvant chemotherapy with a single agent, isofosamide or doxorubicin, has been used,11 and combination chemotherapy (which did not show any superiority) has non-proven value over a single agent.13 Due to its rarity, heterogeneity, and aggressiveness, there is no consensus regarding the optional therapeutic approaches with considerable variation in the type of surgery and choice of adjuvant treatment. The purpose of this study is to investigate the clinical and histopathological characteristics, with the prognostic factors, treatment outcome, and pattern of relapse and survival analysis of uterine sarcoma patients.     

Uterine artery embolisation for uterine fibroids: Our experience at a tertiary care service hospital

Background

Uterine artery embolisation (UAE) has evolved as a minimally invasive and effective alternative, treatment modality for women with symptomatic fibroids. We discuss our initial experience of UAE in the management of symptomatic fibroids.

Methods

Twenty five symptomatic patients of uterine fibroids were treated with UAE by selectively cannulating and injecting poly vinyl alcohol particles into the uterine arteries. Post treatment follow up was done at 2 and 6 months respectively.

Results

Pre-treatment, the sizes of fibroids were between 3.9 and 10.9 cm (mean 7.4) on ultrasonography. Of the total 25 patients, 49 uterine arteries were embolised with a technical success rate of 98%. Menorrhagia persisted in 7 patients, dysmenorrhea in 4 patients and pressure symptoms in 2 patients respectively in follow up study of six months which corresponds to a reduction in symptoms by 68% for menorrhagia, 71% for dysmenorhoea and 75% for those with pressure symptoms respectively. At 2 months follow-up post embolisation, the mean diameter of the fibroid was 4.03 cm (range 2–5.2 cm) and at 6 months 3.2 cm (range 1.3–4.1 cm), corresponding to size reduction of 45.5% and 57%, respectively. Follow up with ultrasonography at 2 and 6 months period showed successful fibroid reduction in 24 patients with corresponding reduction in the symptomatology. One patient remained symptomatic with increase in fibroid size and had to undergo hysterectomy.

Conclusion

Uterine artery embolisation can be considered as an alternative to hysterectomy in appropriately selected symptomatic patients of uterine fibroids.     

Obstetrical Disease Spectrum in China: An Epidemiological Study of 111,767 Cases in 2011

Background:

No national research on maternal and fetal complications and outcomes has been carried out in the mainland of China in recent years. This study was to provide a scientific basis for better control of obstetrical and neonatal diseases and better allocation of medical resources by analyzing the epidemiological characteristics of obstetrical diseases in the mainland of China.

Methods:

Hospitalized obstetrical cases from 19 tertiary and 20 secondary hospitals in 14 provinces (nationally representative) during the period January 1, 2011 to December 31, 2011 were randomly selected. The general condition, pregnancy complications, and perinatal outcomes of the patients were studied.

Results:

The top five medical and surgical complications of pregnant women in the mainland of China were anemia (6.34%), uterine fibroids (2.69%), thyroid disease (1.11%), thrombocytopenia (0.59%), and heart disease (0.59%). The incidences of premature rupture of membranes (PROM), preterm birth, prolonged pregnancy, hypertensive disorders complicating pregnancy (HDCP), multiple pregnancy, intrahepatic cholestasis of pregnancy (ICP), placenta previa, placental abruption, postpartum hemorrhage, and amniotic fluid embolism were 15.27%, 7.04%, 6.71%, 5.35%, 1.57%, 1.22%, 1.14%, 0.54%, 3.26% and 0.06%, respectively. The incidences of anemia and prolonged pregnancy were significantly lower in tertiary than secondary hospitals (P < 0.001), whereas the incidence of uterine fibroids, thyroid diseases, thrombocytopenia, heart disease, PROM, preterm birth, HDCP, multiple pregnancy, ICP, placenta previa, and placental abruption were significantly higher in tertiary than secondary hospitals (P < 0.001). The cesarean section (CS) rate was 54.77%. The newborn sex ratio was 119:100, and 1.03% of the neonates were malformed. The percentages of low birth weight and fetal macrosomia in full-term babies were 2.10% and 7.09%, respectively.

Conclusions:

The incidence of some obstetrical diseases is still high in the mainland of China. The CS rate is much higher than World Health Organization recommendations, in which CS delivery by maternal request (CDMR) accounted for a large proportion. The government should propose solutions to reduce CS rate, especially the rate of CDMR. Most obstetrical complications have higher incidence in tertiary hospitals compared with secondary hospitals. It is important to manage the health of pregnant women systematically, especially those with high-risk factors.
