Antibody response to Covid-19 vaccine (AstraZeneca) amongst Healthcare Workers in a Tertiary Hospital in Nigeria.

BACKGROUND: With no known cure, accelerated development of vaccines became pertinent to contain the COVID-19 pandemic. OBJECTIVES: To assess the IgG antibody response to the viral spike protein and determinants of developing IgG antibodies after vaccination with two doses of the AstraZeneca vaccine. METHODS: This was a prospective cohort study amongst healthcare workers. Serum samples were obtained before vaccination and at 4 and 12 weeks after the first and second doses of the vaccine respectively. Qualitatively testing for the presence of IgG antibodies to the viral spike protein was conducted using the Vidas SARS-CoV-2 IgG and IgM analyser while IgG antibodies were quantitatively assessed by antibody titre estimation using a stepwise two-fold serial dilution method. RESULTS: A total of 155 subjects between the ages of 25 to 64 years were studied. 85 (54.8%) had positive anti-spike IgG antibodies before vaccination. Out of the remaining 70 subjects, 87.3% and subsequently 96.2% developed IgG antibodies to the viral spike protein 4 and 8 weeks after the first and second doses of the vaccine respectively. The AstraZeneca vaccine was found to stimulate antibody response more than natural infection. Prior positive IgG antibodies from natural infection was found to boost antibody response to vaccination. The antibody titre levels rose with vaccination but waned overtime after the second dose of the vaccine. CONCLUSION: The AstraZeneca COVID-19 vaccine elicits an immunogenic IgG antibody response that is augmented by prior infection but however declines a few weeks after the second dose of the vaccine. CONTEXTE: En l'absence de remède connu, le développement accéléré de vaccins est devenu pertinent pour contenir la pandémie de COVID-19. OBJECTIFS: Évaluer la réponse des anticorps IgG à la protéine de pointe virale après vaccination avec deux doses du vaccin AstraZeneca. MÉTHODES: Il s'agissait d'une étude de cohorte prospective parmi les travailleurs de la santé. Des échantillons de sérum ont été obtenus avant la vaccination et à 4 et 12 semaines après la premier et la deuxième doses du vaccin respectivement. Des tests qualitatifs pour la présence d'anticorps IgG dirigés contre la protéine de pointe virale ont été effectués à l'aide de l'analyseur Vidas SARS-CoV-2 IgG et IgM, tandis que les anticorps IgG ont été évalués quantitativement par estimation du titre d'anticorps à l'aide d'une méthode de dilution en série en deux étapes. RÉSULTATS: Au total, 155 sujets âgés de 25 à 64 ans ont été étudiés. 85 (54,8 %) avaient des anticorps IgG anti-pic positifs avant la vaccination. Sur les 70 sujets restants, 87,3 % puis 96,2 % ont développé des anticorps IgG contre la protéine de pointe virale 4 et 8 semaines après la première et la deuxième doses du vaccin respectivement. Le vaccin AstraZeneca s'est avéré stimuler la réponse anticorps plus que l'infection naturelle. Des anticorps IgG antérieurement positifs d'une infection naturelle ont été trouvés pour stimuler la réponse des anticorps à la vaccination. Les niveaux de titre d'anticorps ont augmenté avec la vaccination mais ont cependant diminué avec le temps après la deuxième dose du vaccin. CONCLUSIONS: Le vaccinAstraZeneca COVID-19 suscite une réponse immunogène en anticorps IgG qui est augmentée par une infection antérieure mais qui décline cependant quelques semaines après la deuxième dose du vaccin.

Blood Group Distribution among COVID-19 Patients in a Nigerian Treatment Centre.

BACKGROUND: Biomarkers of susceptibility to COVID-19 are being investigated by many scientists all over the world. The ABO blood group antigens are the most frequently studied genetic markers. Reports from China and USA have shown that people with blood group A are more susceptible to COVID- 19 while those with blood group O are least susceptible. METHODS: The ABO blood group of 51 patients with COVID-19 admitted at the University of Abuja Teaching Hospital, Nigeria was determined and compared with the ABO blood group distribution in the general population. RESULTS: Out of the 51 patients, 39 (76.5%) were males and 12 (23.5%) were females, giving a male: female ratio of 3.25:1. Out of the 51 patients, 29 (56.9%) had blood group O, 12 (23.5%) had blood group A, 10 (19.6%) had blood group B and none (0%) had blood group AB. This blood group distribution was comparable to the blood group distribution in the general population. CONCLUSION: Preliminary analysis of the blood group distribution of COVID-19 patients being managed at the University of Abuja Teaching Hospital in Nigeria found no relationship between COVID-19 and ABO blood group. More studies are needed particularly in Africa to determine if ABO blood group can be a biomarker of susceptibility to COVID-19 among Africans.

CONTEXTE: Les biomarqueurs de sensibilité au COVID-19 sont étudiés par de nombreux scientifiques du monde entier. Les antigènes des groupes sanguins ABO sont les marqueurs génétiques les plus fréquemment étudiés. Des rapports de Chine et des États-Unis ont montré que les personnes du groupe sanguin A sont plus sensibles au COVID-19 tandis que celles du groupe sanguin O sont les moins sensibles. MÉTHODES: Le groupe sanguin ABO de 51 patients atteints de COVID 19 admis à l'hôpital universitaire d'Abuja, au Nigéria, a été déterminé et comparé à la distribution des groupes sanguins ABO dans la population générale. RÉSULTATS: Sur les 51 patients, 39 (76,5%) étaient des hommes et 12 (23,5%) étaient des femmes, ce qui donne un rapport homme: femme de 3,25: 1. Sur les 51 patients, 29 (56,9%) avaient le groupe sanguin O, 12 (23,5%) avaient le groupe sanguin A, 10 (19,6%) avaient le groupe sanguin B et aucun (0%) n'avait le groupe sanguin AB. Cette distribution des groupes sanguins était comparable à la distribution des groupes sanguins dans la population générale. CONCLUSION: Une analyse préliminaire de la distribution des groupes sanguins des patients COVID-19 pris en charge à l'hôpital universitaire d'Abuja au Nigéria n'a trouvé aucune relation entre le groupe sanguin COVID-19 et ABO. D'autres études sont nécessaires, en particulier en Afrique, pour déterminer si le groupe sanguin ABO peut être un biomarqueur de la sensibilité au COVID-19 chez les Africains. MOTS CLÉS: Groupe sanguin ABO, COVID-19, biomarqueur.

COVID-19 and Mycobacterium Tuberculosis Coinfection: A Case Report.

COVID-19 is a global pandemic, with attendant high morbidity and mortality. There is no previous documentation of its coinfection with Mycobacterium tuberculosis; the single most common cause of death from an infectious disease. Management and survival from this "cruel duel" in a low resource country will be daunting. We report the case of a middle-aged man who survived and the lessons learned from a COVID-19 treatment centre in the north-central of Nigeria. The patient presented with symptoms and clinical features of COVID-19 and Mycobacterium tuberculosis was confirmed with laboratory investigation. The patient commenced anti-tuberculous medications, received nutritional support and other supportive treatment for COVID-19 infection. He was discharged home to continue follow up at the medical outpatient and the DOTS clinic. Early recognition and prompt treatment are critical for a favourable clinical outcome.

Prevalence and outcome of increased nuchal translucency in usmanu danfodiyo university teaching hospital, Sokoto, Nigeria: A cohort study.

BACKGROUND: An important component of the first-trimester scan is nuchal translucency thickness at 11 weeks to 13 weeks 6 days of gestation. A nuchal translucency ≥3.3 mm is a significant early pregnancy scan finding associated with Trisomies 13, 18, and 21 and congenital heart diseases. AIMS: To determine the prevalence and outcome of increased fetal nuchal translucency among pregnant women. SUBJECTS AND METHODS: A prospective cohort study at the Obstetrics and Gynaecology Department of Usmanu Danfodiyo University Teaching Hospital Sokoto. This was a prospective study of 265 consecutively recruited women in the first trimester of pregnancy who presented to antenatal clinics over a 20-week period. An NT scan was conducted at 11 weeks to 13 weeks 6 days followed by an anomaly scan at 18-22 weeks. Patients were followed up to delivery and 6-week post-partum. The neonates were examined at delivery and at 6-week postnatal life. Data entry and analysis was done with IBM SPSS version 20. The level of significance was set at less than 0.05. Frequency distribution; student t-test and Chi-squared test. RESULTS: The 95th percentile NT was 3.3 mm and the prevalence of increased NT above 3.3 mm was 3%. The mean maternal age of the participants was 28.1 ± 5.1 years and the modal parity was Para 0. The most common anomalies associated with increased NT were ventricular septal defect and spina bifida. A congenital anomaly was significantly associated with increased NT (P < 0.001). CONCLUSIONS: The prevalence of increased fetal nuchal translucency is relatively high in our environment and is associated with congenital fetal defects. Routine screening with first-trimester ultrasound will help detect congenital anomalies early.

Association between maternal lipid profile and gestational diabetes mellitus

Background: Dyslipidemia is the third component of metabolic syndrome and is a wellknown cardiovascular risk factor. However, the association of dyslipidemia with gestational diabetes mellitus is still a subject of ongoing research in Nigerian obstetric populations.Objective: To determine the relationship between second trimester maternal fasting plasma lipid constituents and gestational diabetes mellitus.Methods: This was a prospective nested case control study that enrolled 288 pregnant women out of which 36 women with GDM (cases) where matched with 72 without GDM (controls) following results of oral glucosetolerance testing and plasma fasting lipid profiles done between 24 28 weeks. The patients were followed up until delivery to document maternal and fetal outcomes. Data was analyzed using Statistical Package for Social Sciences (SPSS). Categorical variables were presented in percentages while continuous variables were expressed as means (±Standard Deviation). Student ttest and Chisquare test or Fishers exact test were used for comparing variables between the two groups. A value of <0.05 at 95%confidence interval was considered statistically significant.Results: The overall mean plasma lipid levels for the four lipid constituents in the study population were 187.9mg/dL, 163.5mg/dl, 49.1mg/dL and 108.1mg/dL for TC, TG, HDLc and LDc respectively. The mean plasma triglyceride was significantly higher in cases compared to the controls: 187.0±67.7mg/dL vs. 151.7±66.4mg/dL, (p = 0.01). Abnormaltriglyceride was significantly associated with GDM (AOR:4.8, 95% CI (1.6-14.4), (p= 0.005).Conclusion:Maternal dyslipidemia (abnormal triglyceride) was shown to be significantly associated with GDM in this study and it appeared to be causally related

Maternal near-miss and death among women with hypertensive disorders in pregnancy: a secondary analysis of the Nigeria Near-miss and Maternal Death Survey.

OBJECTIVE: To investigate life-threatening maternal complications related to hypertensive disorders of pregnancy (HDP) in Nigerian public tertiary hospitals. DESIGN: Secondary analysis of a nationwide cross-sectional study. SETTING: Forty-two tertiary hospitals. POPULATION: Women admitted for pregnancy, childbirth or puerperal complications. METHOD: All cases of severe maternal outcome (SMO: maternal near-miss or maternal death) due to HDP were prospectively identified using the WHO criteria over a 1-year period. MAIN OUTCOME MEASURES: Incidence of SMO, health service events, case fatality rate, and mortality index (% of maternal death/SMO). RESULTS: Out of 100 107 admissions for maternal complications, 6753 (6.8%) women had HDP. Pre-eclampsia (PE) (54.5%) and eclampsia (E) (30.4%) were the most common HDP recorded. SMO occurred in 587 women with HDP: 298 maternal near-misses and 289 maternal deaths. The majority (93%) of the women with SMO due to HDP were admitted in a critical condition. The median diagnosis-definitive intervention interval was over 4 hours in a quarter of women who died from HDP. For PE and E, case fatality rates were 1.9 and 10.4%, respectively, although both conditions had a similar mortality index of 49.3%. Lack of antenatal care and place of residence further than 5 km from the hospital were associated with maternal death. CONCLUSIONS: Severe maternal outcomes from HDP were due to late presentations and health system challenges. To reduce maternal deaths from HDP, health system strengthening that would engender early hospital presentation and prompt treatment is recommended. FUNDING: The original research that generated the data for this secondary analysis was funded by the UNDP/UNFPA/UNICEF/WHO/World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP), a co-sponsored programme executed by the World Health Organization (WHO). We have no other funding issue to declare for our study. TWEETABLE ABSTRACT: Eclampsia is the leading cause of maternal death in Nigerian hospitals.

When getting there is not enough: a nationwide cross-sectional study of 998 maternal deaths and 1451 near-misses in public tertiary hospitals in a low-income country.

OBJECTIVE: To investigate the burden and causes of life-threatening maternal complications and the quality of emergency obstetric care in Nigerian public tertiary hospitals. DESIGN: Nationwide cross-sectional study. SETTING: Forty-two tertiary hospitals. POPULATION: Women admitted for pregnancy, childbirth and puerperal complications. METHODS: All cases of severe maternal outcome (SMO: maternal near-miss or maternal death) were prospectively identified using the WHO criteria over a 1-year period. MAIN OUTCOME MEASURES: Incidence and causes of SMO, health service events, case fatality rate, and mortality index (% of maternal death/SMO). RESULTS: Participating hospitals recorded 91 724 live births and 5910 stillbirths. A total of 2449 women had an SMO, including 1451 near-misses and 998 maternal deaths (2.7, 1.6 and 1.1% of live births, respectively). The majority (91.8%) of SMO cases were admitted in critical condition. Leading causes of SMO were pre-eclampsia/eclampsia (23.4%) and postpartum haemorrhage (14.4%). The overall mortality index for life-threatening conditions was 40.8%. For all SMOs, the median time between diagnosis and critical intervention was 60 minutes (IQR: 21-215 minutes) but in 21.9% of cases, it was over 4 hours. Late presentation (35.3%), lack of health insurance (17.5%) and non-availability of blood/blood products (12.7%) were the most frequent problems associated with deficiencies in care. CONCLUSIONS: Improving the chances of maternal survival would not only require timely application of life-saving interventions but also their safe, efficient and equitable use. Maternal mortality reduction strategies in Nigeria should address the deficiencies identified in tertiary hospital care and prioritise the prevention of severe complications at lower levels of care. TWEETABLE ABSTRACT: Of 998 maternal deaths and 1451 near-misses reported in a network of 42 Nigerian tertiary hospitals in 1 year.

Uterine rupture: trends and feto-maternal outcome in a Nigerian teaching hospital.

OBJECTIVE: To determine the trends, predisposing factors, maternal and fetal outcome of cases of uterine rupture managed at the University of Abuja Teaching Hospital. METHOD: A retrospective review of all cases of ruptured uterus managed at the University of Abuja teaching hospital, Gwagwalada, between January 2006 and December 2010 was conducted. RESULT: There were 9604 deliveries in the hospital during the period of review out of which 82 were cases ruptured uterus, giving an overall incidence of 0.85% or 1 in 117 deliveries. They were mainly women of low parity with a mean age of 31.8 years. The commonest predisposing factor was injudicious use of oxytocin occurring in 38.7% of cases and was followed closely by previous caesarean section scar (28.0%). Prolonged obstructed labour was the third commonest cause of uterine rupture (18.7%) and occurred only in the unbooked patients. There were 11 maternal deaths which gave a maternal case fatality rate of 14.7%. All the deaths occurred in women who had intrapartum care in places other than the teaching hospital. There were 68 perinatal deaths which gave a fetal case fatality rate of 90.7% and all the babies that survived were in patients that had intrapartum care in the teaching hospital. CONCLUSION: Ruptured uterus is a common obstetric emergency in Nigeria's Federal Capital territory and is associated with high maternal and perinatal morbidity and mortality. It is however preventable when the quality of antenatal care, intrapartum care and medical facilities are improved.

Pregnancy outcome in women with eclampsia at a tertiary centre in northern Nigeria.

BACKGROUND: Eclampsia is a major cause of maternal and perinatal morbidity and mortality. The objectives of this study were to determine pregnancy outcome in women with eclampsia especially the maternal and perinatal deaths and the various contributory factors. MATERIALS AND METHOD: A retrospective analysis of demographic and clinical data of patients with eclampsia over a ten-year period (2000-2009) with particular reference to fetal and maternal outcome. Statistical analysis was by Epi- info computer package while test of significance between proportions was done using chi square. Ap value less than 0.05 was considered significant. RESULTS: 23,266 deliveries were conducted and 1027 cases of eclampsia were managed within the 10-yr period giving an incidence of 4.4%. The patients were mainly primigravidae (76%, N=778) with no antenatal care (93.4%, N=959); mean age was 21 years. Intrapartum eclampsia accounted for 62.6%, (N=643). About 45% (N=643) delivered spontaneously, 28.7% (N=277) had instrumental delivery while 19.6% (N=189) had caesarean section. Of the 621 maternal deaths for the period, eclampsia contributed to 29.4% (184) with a case fatality rate of 17.9%. Case fatality in the two years (2006/2007) when magnesium sulphate was used only on eclamptics with repeat fits (because of limited supply) was 18.2% which was not significantly different from the 20.0% fatality recorded in the two years (2008/2009) the drug was used routinely as the sole anticonvulsant agent P > 0.05. Maternal deaths were significantly more amongst the multiparous women with eclampsia (23.3%) than the primigravidae (16%); mortality was also more in eclamptics who had no antenatal care (18.7%) than those with care (5.9%), p <0.05. Major maternal complications were aspiration pneumonitis (23.9%) and pulmonary oedema (16.3%), hyperpyrexia (17.9%), acute renal failure (11.4%), and cerebrovascular accidents 9.8%. Total perinatal deaths were 392 with 81.1% (318/392) still births and 18.9% (74/392) early neonatal deaths mainly from severe birth asphyxia. Perinatal mortality ratio was 406/1000. CONCLUSION: The incidence of eclampsia in the study group was high. It was a major direct cause of maternal and perinatal deaths. Maternal outcome was also poor even with the introduction of magnesium sulphate. Interventions for reduction of maternal and perinatal mortality must emphasize on strategies that prevent the occurrence of eclampsia since outcome in some settings is still not very favorable when it does occur.

Age at menarche among school girls in Sokoto, Northern Nigeria.

BACKGROUND/OBJECTIVES: Menarche, the first menstrual period, is influenced by many factors including socio-economic status and rural or urban dwelling. The aims of the study were to compare the age at menarche between rural and urban girls and evaluate the anthropometric indices at menarche. MATERIALS AND METHODS: A cross-sectional study of rural secondary school girls and urban school girls. A structured questionnaire was used to obtain information on their age at menarche and other relevant data. Their weights and heights were measured using computerized scales and calibrated walls. RESULTS: Two hundred and twenty eight (228) rural girls and four hundred and eighty (480) urban girls that had attained menarche within a year were studied. Mean age at menarche for all the girls was 15.26 years. Mean menarcheal age for the rural and urban girls were 15.32 years and 15.20 years, respectively. Mean weight and height were 47.6 kg and 156.76 cm, respectively for the rural girls and 48.12 kg and 156.8 cm, respectively for the urban girls. There was no significance difference in age of menarche among the groups (P > 0.05). CONCLUSION: The mean age at menarche for the school girls is 15.26 years. There was no difference in menarcheal age between the rural and urban school girls. Further longitudinal studies to compare rural school girls and urban school girls in private schools are required.

Do women want disclosure of fetal gender during prenatal ultrasound scan?

BACKGROUND/OBJECTIVES: It is possible that not all women would want the disclosure of fetal gender by the sonologist during a prenatal scan. The objectives of this study were to determine the proportion of women who do not want fetal gender disclosure at the time of prenatal ultrasonography and document their reasons. METHOD: A cross-sectional survey of women that were 20 weeks or more pregnant that had prenatal ultrasound at a private health facility in January 2006. The sonologist asked each of the women during the procedure whether they wanted to know fetal sex or not. Those that consented had disclosure of fetal sex while those that declined gave their reasons, which were documented. RESULTS: Two hundred and one (201) women were studied within the study period. Most of the women (82%) were of the Hausa/Fulani ethnic group and were predominantly of the Islamic faith (90%). One hundred and ninety women (94.5%) consented to disclosure of fetal gender, while eleven (5.5%) declined. The main reason for not wanting to know fetal sex was: 'Satisfied with any one that comes'. CONCLUSION: Most of the pregnant women (94%) would want disclosure of fetal gender at prenatal ultrasound scan. Only 5.5% of the women would not want fetal sex disclosure because they were satisfied with whichever that was there. It is advisable for the sonologist to be discrete on what to say during the procedure especially as it relates to fetal sex so as not to hurt those that do not want disclosure.

Determinants of Utilization of Maternity Services in Gidan Igwe; Sokoto; Nigeria

Background: The provision of antenatal care is regarded as the cornerstone of maternal and perinatal health care especially in developing nations and is expected to have a significant impact on achieving the fifth millennium development goal. The aim of this study was to assess the determinants of utilisation of maternity services in Gidan Igwe; Sokoto. Methods: The study was a cross-sectional descriptive one involving 300 women of child bearing age selected through a systematic sampling technique. Data was collected using a set of semi-structured interviewer and self administered questionnaires. Results: Majority; 214 (71.3) of the respondents had no formal education; visited a health facility for antenatal care during their last pregnancy; 218 (72.7) and had their last delivery at home; 190 (63.3). Of the 190 subjects that delivered at home; 165 (85) were assisted by Traditional birth attendants (TBAs). Education was statistically significantly associated with ANC attendance and hospital delivery (P=0.0012). Conclusion: Although; a high proportion of the respondents visited health facilities for ANC; only a few of them delivered in these facilities. There is need to increase public awareness on the use of antenatal care services and delivery by skilled attendants

Vesicovaginal fistula: do the patients know the cause?

BACKGROUND: So much has been written on vesicovaginal fistula (VVF) but there is little on the patients' perspective of the condition. The objectives of this study were to determine the knowledge of patients who have developed VVF on the causes of the fistula and their attitude toward measures that would prevent future occurrence. METHODS: The questionnaire-based survey was conducted on VVF patients on admission from June to August 2003 at Maryam Abacha Women and Children Welfare Hospital, Sokoto, Nigeria. The case notes of the patients were reviewed after the interview to match the responses from the patients with those documented in the folders. Focus group discussions were held with the maternity staff to ascertain the content and quality of existing counseling. RESULTS: One hundred and thirty patients were studied out of which 121 (93%) had no formal education. Teenagers constituted 37%, while 57% were primiparae. Thirty-five (27%) patients were divorced or separated because of the VVF. There were seven cases of recurrence after a previous successful repair. Prolonged obstructed labor was the cause of the VVF in 110 (85%) patients and 77 (70%) correctly attributed their problem to the prolonged labor. The 33 patients who could not identify the prolonged obstructed labor as the cause either attributed their condition to God/destiny or to the operation that was done to relief the obstruction and therefore would not have hospital delivery in their subsequent pregnancies. From the focus group discussions, it was confirmed that pre and post-operative counseling were inadequate. CONCLUSION: Even though majority (70%) of the patients knew the cause of their fistula from the health talks, some (32%) would still not change from risky obstetric behavior. Mandatory provision of accurate and appropriate information and education to all VVF patients and their relatives or spouses by trained counselors should be ensured. Such information and education should emphasize the etiology and management of obstetric fistula in order to prevent a recurrence.

What is the place of the new WHO antenatal care model in a teaching hospital setting?

The basic component of the new World Health Organization (WHO) antenatal care model prescribes reduced number of clinic visits and limited investigations for low-risk pregnant women. The objectives of this study were to determine the proportion of pregnant women seeking antenatal care in a Nigerian teaching hospital who qualify for the basic component and to document difficulties that may arise with the classifying form. In December 2004, 234 pregnant women who had initiated antenatal care were enrolled for the study. Using the classifying form, 157 (67%) were eligible for the basic component, 41 (18%) for special care, but 36 (15%) women could not be classified. Those that did not know the birth weight of their last babies accounted for most (89%) of the unclassified group. The WHO antenatal care model was the most appropriate and relevant method for our hospital where a large percentage (67%) of prenatal women were eligible for the basic component. However, we consider that the classifying form should be adapted to accommodate all pregnant women.

Abdominal pregnancy with a full term live fetus: case report.

This is a case report of an abdominal pregnancy that was carried to term with live fetus. Illiteracy, poverty and lack of antenatal care had resulted in her late presentation. Bleeding per vagina, persistence abdominal pain, weight loss and pallor were the main clinical features. She had laparotomy and delivery of a live fetus.

Misoprostol use for cervical ripening and induction of labour in a Nigerian teaching hospital.

CONTEXT: Induction of labor is always a challenge to many an obstetrician more so when the cervix is unfavorable. OBJECTIVES: To determine the efficacy and safety ofmisoprostol in cervical ripening and labour induction. MATERIALS AND METHOD: Aprospective study spanning 2 years and involving 151 patients admitted for cervical ripening and induction of labor at Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria. 50 microgram (mcg) ofmisoprostol was inserted vaginally every 4 hours until cervix became favorable or onset of labor. RESULTS: Main indications for induction of labour were prolonged pregnancy and hypertensive diseases of pregnancy. An average of 2 insertions of 50 mcg tablet was used to achieve cervical ripening in 107 patients (71%) and 80% (120) had spontaneous labor within 10 hours of insertion. The mean insertion-labor interval was 7.86 hours (SD +/- 2.5). The average duration of labour was 9.36 hours (SD +/- 2.9). Vaginal delivery was achieved in 96% of the patients. Uterine hyperstimulation occurred in 9 patients but there was no case of uterine rupture. CONCLUSION: Misoprostol was effective and safe in cervical ripening and induction of labor with a vaginal delivery rate of 96%. It should be an essential drug in obstetric practice especially in low resource settings.

Clusters of eclampsia in a Nigerian teaching hospital.

OBJECTIVE: To describe the pattern of eclampsia between 1995 and 2004 at the Usmanu Danfodiyo University Teaching Hospital, Sokoto, northwestern Nigeria. STUDY DESIGN: A retrospective cohort of all deliveries and eclamptics seen from 1st January 1995 to 31st December 2004. Clusters of eclampsia were identified using purely temporal scan statistics. RESULTS: Of 15,318 deliveries during the period, 657(4.29%) had eclampsia. The yearly incidence of eclampsia at the beginning of the study period (1995) was 0.39% but this had increased to 7.0% in 2004 at a background exponential rate best described by quadratic curve fitting prediction model and a forecast curve that predicts an incidence of eclampsia of at least 32.4% of total deliveries by 2009. Temporal clusters occurred in 1996, 2001 and 2003-2004. CONCLUSION: The incidence of eclampsia is unusually high and is increasing. It has shown 3 clusters in the last 10 years.
