Journal of Environmental Science and Engineering(B) 2013年第7期2卷 426-431页

作者： Ihesinachi Appolonia Kalagbor Stella Adedunni Emmanuel Deparment of Science Laboratory Technology School of Applied Sciences Rivers State Polytechnic Bori 0001 Nigeria Chemistry Advanced Laboratory Department Sheda Science and Technology Complex Abuja 09 Nigeria

The physicochemical and microbiological assessments of thirteen accessible boreholes in Rumukalagbor in port harcourt were ascertained. The studies were carried out in April （onset of the rains） and June （peak of the rains） and the results obtained showed that all the water samples tested were acidic （pH 3.12-5.18） with the samples having lower values in June. Eight boreholes （61.5%） had high conductivity values and all boreholes recorded high TDS （total dissolved solids）.These are indications of the presence of dissolved minerals/polluting agents. TH （total hardness） values for all the borehole samples were very low （20 mg/L-60 mg/L）, which are below WHO （World Health Organization） set limit of 200 mg/L. The levels of Ca and Mg ions were determined using AAS （atomic absorption spectroscopy） and these were also observed to be very low. Ca ion concentrations were 0.15 mg/L-20.1 mg/L and Mg ion concentrations were 0.10 mg/L-10.3 mg/L. All the samples but one exceeded the WHO limit for chloride ion concentration for potable water. These high levels can account for the high pH and conductivity values and since water from some boreholes are soft, they are prone to plumbosolvacy. Sulphate and nitrate concentrations in the samples are within the WHO allowable limits. The water samples showed minimal microbial load with 38.5% not having any microbial load.

Background: Client satisfaction is considered as one of the desired outcomes of health care service delivery and it is directly related to the utilization of any health services. The family planning clinic remains one of the important health care delivery outlets where client satisfaction guarantees continuation of usage, hence this study. Objective: The objective of this study is to assess the determinants of client satisfaction with the family planning (FP) services provided in port harcourt. Materials and methods: This was a descriptive prospective cross-sectional study conducted between 18th of June 2018 and 18th of July 2018. The target population is women of reproductive age group (15 - 49) who visited 11 randomly selected family planning health facilities in port harcourt during the study period. A set of exit interviewer-administered questionnaire (pretested for reliability and validity) was used for data collection from a sample size of 195 respondents;and analyzed using SPSS 22.0. Standard deviation was used for continuous variable while categorical variables were presented in simple percentages and frequencies. The P value was set at Results: Age range 30 - 39 years constituted the largest proportion of 51.3%. A large proportion of the women (87.2%) expressed satisfaction with FP services provided. All respondents said the facilities were easily accessible, clean and were treated respectfully. However, only about half of the clients (51.3%) received their chosen contraceptive product after 1 hour. Conclusion: A huge proportion of family planning clients expressed satisfaction with family planning service delivery in port harcourt;not minding the longer waiting time. Implication of this is continued use and by implication improved contraceptive prevalence.

The air quality index (AQI) of a location informs how clean or unhealthy the ambient air is. While COVID-19 pandemic on one hand threatened the health of mankind globally, on the other hand was a respite to poor air quality of most cities. This study evaluated the positive effects of the brief COVID-19 lockdown on the air quality of port harcourt city, Nigeria. Air quality parameters aimed at assessing air quality index of port harcourt Metropolis before, during and after COVID-19 pandemic lockdown were monitored and compared. Data were analysed and AQI of sampled locations computed using the US EPA recommended standard procedure. Results from the study showed that, the ambient air quality of port harcourt was hazardous for breathing before lockdown. During shutdown of activities, the air quality improved to unhealthy status, with an average reduction AQI of 261.7 points. However, an average increase of 100.7 points, resulting to very unhealthy air status for residents after lockdown was observed. The unhealthy status during lockdown shows that anthropogenic activities were still on despite the Pandemic shutdown of economic activities. Also, decrease in levels of the criteria air pollutants was observed. Before lock down, the range levels of SO3, NO2, CO, O3, PM2.5 and PM10 were 3, 15 - 135 μg/m3, respectively. In the period of lockdown, the levels reduced considerably, especially CO and PM2.5 and PM10 (1 - 12 ppm, 5 - 60 μg/m3, and 10 - 50 μg/ m3). Conversely, after lockdown, there was upsurge in levels of the pollutants, especially CO and PM2.5 and PM10 (4 - 16 ppm, 10 - 110 μg/m3, 10 - 90 μg/m3). Authorities are expected to establish routine air quality measurements stations and communicate daily air quality to residents, for public he

Open Journal of Obstetrics and Gynecology 2023年第2期13卷 265-279页

作者： Darlington Omawumi Emmanuel Oranu Rosemary Ogu Ngozi Orazulike Job Otokwala Department of Obstetrics and Gynaecology University of Port Harcourt Teaching Hospital Port Harcourt Nigeria Department of Anaesthesiology University of Port Harcourt Teaching Hospital Port Harcourt Nigeria

Background: Blood loss during caesarean section (C/S) may lead to postpartum haemorrhage, and is one of the direct causes of maternal mortality and morbidity globally. Tranexamic acid is recommended in the treatment of postpartum haemorrhage (PPH) if oxytocin and other utertonics are ineffective in controlling PPH. In this centre it is not used prophylactically to reduce blood during caesarean section. Aim: To assess the effect of prophylactic intravenous tranexamic acid on blood loss during and after elective C/S at the University of port harcourt Teaching Hospital (UPTH). Methods: This was a prospective, single-blind, randomized, placebo-controlled interventional study conducted at the Obstetric theatre of UPTH from July 2020 to March 2021. Eligible women were randomized into two groups;seventy-two women received intravenous tranexamic acid while seventy-one women received a placebo. Socio-demographic data and the result of the study were collected through a proforma. Data collected was analyzed using Statistical Package for Social Sciences (SPSS) Version 22.0. The results were expressed in tables and charts as frequencies, percentages and mean. Chi-square test, Fisher’s exact, and T-test were used to determine the relationship between variables. P-value ≤ 0.05 was considered statistically significant. Results: The findings showed that tranexamic acid significantly reduced mean blood loss during and after C/S (p-value post-surgery was significantly lower in the tranexamic acid group (624.88 ± 200.76 ml) in comparison to the placebo group (864.24 ± 229.09 ml), p-value = 0.001. The mean post-C/S packed cell volume (PCV) was significantly higher among the tranexamic acid group (30.68% ± 2.80%) in comparison to the placebo group (28.07% ± 3.27%), t = 5.131, p-value = 0.0001. The maternal side effects were nausea and vomiting, 9 (12.5%) and 1 (1.4%) participants respectively. Conclusion: Tranexamic acid significantly reduced blood loss during and after elective C/S. Ma

Diagnostic Accuracy of Hysterosalpingography in the Identification of Intrauterine Adhesions in Infertile Women in a Referral Centre, Southern Nigeria

引用

Open Journal of Obstetrics and Gynecology 2023年第2期13卷 291-302页

作者： Inusa Amike Emmanuel Okwudili Oranu Tamunomie Kennedy Nyengidiki Enighe W.

Background: Examination of the endometrial cavity is crucial in the management of infertile women. This evaluation is done by Hysterosalpingography (HSG) in the University of port harcourt Teaching Hospital. The diagnostic value and accuracy of hysterosalpingography varies in various centres and has not been assessed in the University of port harcourt Teaching Hospital (UPTH), hence this study. Methodology: A prospective cross sectional study done among 101 infertile women at the gynaecology clinic of the UPTH from December 2018 to July 2019. Socio-demographic data of women who met the eligibility criteria were collected. Their hysterosalpingographic and outpatient hysteroscopic findings were statistically analyzed using IBM SPSS for windows version 20.0. The validity and reliability statistics of hysterosalpingography for the identification of endometrial adhesions were determined and significance was reported at p-value < 0.05. The analyzed data was presented in tables and figure. Result: The respondents were all married, 66.3% of them were nulliparous, while 54.5% were above 35 years of age. Most, 93.1% of the studied group had at least secondary education and had duration of infertility of more than 2 years. There was a moderate strength of agreement in the diagnostic accuracy of HSG with hysteroscopy in the diagnosis of intrauterine adhesions;showing sensitivity and specificity of 59.6% and 90.9% respectively. The accuracy of HSG in the identification of intrauterine adhesions in this study was 73.3%. The agreement in the diagnostic accuracy of HSG using Hysteroscopy as a gold standard for intrauterine adhesions was therefore moderately significant (k = 0.482). Conclusion: HSG had an overall fair strength of agreement with office hysteroscopy in the identification of intrauterine adhesions. It is a specific but not a sensitive predictor of intrauterine adhesion.
