Abdominal pregnancy misdiagnosed as an intrauterine pregnancy: a cause of failed induction of labour for fetal death

Abdominal pregnancy is a rare form of ectopic pregnancy usually associated with fetal death among other complications, although very rare cases of live births have been reported. There is also a high risk of maternal mortality. A high index of suspicion is required to make a preoperative diagnosis as diagnosis from history, examination and ultrasound is often missed. Misdiagnoses as an intrauterine pregnancy usually occur. This misdiagnosis makes management of patients with an abdominal pregnancy a challenge and may affect treatment outcome. We managed a 35 year old pregnant multipara who was referred to us on account of repeated failed attempts at induction of labour for intrauterine fetal death. Three obstetric ultrasound scans done during the course of patient’s management reported an intrauterine dead fetus. We also failed to achieve uterine evacuation. We resorted to carry out a hysterotomy and following laparotomy, we found an abdominal pregnancy. This finding was unexpected by us, however, we delivered the dead fetus and was able to successfully manage the placenta. Discovering an abdominal pregnancy at surgery carried out for a supposed intrauterine pregnancy is usual for many cases of abdominal pregnancy. Clinicians should be aware of the clinical signs and symptoms that raise a suspicion of abdominal pregnancy as prompt preoperative diagnosis of abdominal pregnancy helps to plan and offer early and appropriate intervention. This reduces the incidence of maternal mortality usually due to massive intra-abdominal haemorrhage arising from delayed diagnosis and poor placenta management. 

QUALITY MANAGEMENT PRACTICES AND COMPETITIVE ADVANTAGE OF SELECTED FOOD AND BEVERAGE MANUFACTURING FIRMS IN LAGOS STATE, NIGERIA

The performance of Food and Beverages manufacturing firms is important to the development of the economy and this has been considered by researchers. In Nigeria, the decline in the performance of this sector in terms of competitive advantage has been noticed which could be as a result of a lack of quality management practices such as leadership behaviour, strategic quality planning, supplier quality management, process management and customer focus. The study investigated the effect of quality management practices on the competitive advantage of selected Food and Beverages manufacturing firms in Lagos State, Nigeria. The survey research design was adopted. The population of the study was 14, 591 top, middle and low-level management employees of the selected Food and Beverages manufacturing firms in Lagos State, Nigeria. A sample size of 491 was determined using the research advisor table. A simple random sampling technique was used. A validated questionnaire was used to collect data. Cronbach’s alpha reliability coefficients for the constructs ranged from 0.866 to 0.954. The response rate was 100%. Data were statistically analysed using descriptive and inferential statistics (multiple and hierarchical regression). Findings revealed that quality management practices had a significant effect on the competitive advantage of Food and Beverages manufacturing firms in Lagos State, (Adj.R2 = 0.117; F (5, 485) = 14.025, p < 0.05). The study concluded that quality management practices affected competitive advantage in Food and Beverages manufacturing firms in Lagos State, Nigeria. The study recommends that Food and Beverages manufacturing firms should encourage the adoption of quality management practices to enhance competitive advantage.  Article visualizations

Planned cesarean myomectomy at term for huge intramural fibroids coexisting with pregnancy: A case report

With about 2–11% of pregnancy co‑existing with fibroids, one in 10 women will have complications related to myoma in pregnancy. The procedure of cesarean myomectomy has been much discouraged and the need to perform inevitable myomectomy during the cesarean section (CS) when fibroids obstruct wound closure has been presented. A case of a primigravida with huge uterine fibroids displacing the fetus into a persistent oblique lie and causing maternal discomfort is presented. A planned cesarean myomectomy was performed. Hemorrhage was controlled with tourniquet using Foley catheter, misoprostol, and high dose oxytocin infusion. The mother and baby had a satisfactory outcome. Elective cesarean myomectomy is safe but should only be done by an experienced surgeon and in centers equipped with facilities for comprehensive emergency obstetric care. Key words: Cesarean myomectomy; cesarean section; fibroids

Effect of Replacing Wheat Offal with Asystasia gangetica Leaf Meal (ALM) on Growth Performance and Haematological Parameters of Weaner Rabbits

A fifty six (56) day feeding trial was carried out to determine the effect of replacing wheat offal with Asystasia gangetica leaf meal (ALM) on the growth performance and haematological parameters of weaner rabbits. Four (4) diets were formulated such that the control diet (T1) contained 0%ALM while T2, T3 and T4 contained 33%, 66% and 100% replacement levels of wheat offal respectively. Twenty-four (24) unsexed and mixed-breed weaner rabbits were randomly assigned to four dietary treatments. Feed and water were offered ad-libitum throughout the period of the experiment. The result of the experiment showed that there were significant differences (P<0.05) in daily weight gain and feed cost/kg gain of rabbits. The experimental diets had no significant effect (P>0.05) on feed intake and feed conversion ratio of the experimental rabbits. There was a decrease in the cost of feed as replacement levels of ALM increased in the diets. Haematological parameters measured were not significantly (P>0.05) different except for WBC. Based on the finding of this study, it was concluded that replacing 66% of wheat offal in the diet of weaner rabbits with ALM will reduce the cost of rabbit production without adverse effects on the growth performance and haematological indices of the rabbits

COMPARISON OF ACTIVITY CONCENTRATIONS OF NATURAL RADIONUCLIDES IN SOILS COLLECTED AT DIFFERENT DEPTHS OF SELECTED HAND-DUG WELLS IN ABEOKUTA

This study was aimed at measuring and comparing the activity concentration of soil samples collected from some selected hand – dug wells with their corresponding depths of collection in Abeokuta metropolis. Total of twenty (20) soil samples were collected from hand-dug wells in five sites (Obada, Adigbe, Kuto, Olorunsogo, and Obantoko) within Abeokuta with four (4) soil samples from each hand-dug well at the surface, (0.0m) through to 2.25m depth. Gamma ray spectroscopy with High Purity Germanium (HPGe) detector was used for the measurements. The average activity concentrations obtained for the three natural radionuclides 226Ra, 232Th and 40K in Bq/Kg are 34.31 ± 2.01, 128.73 ± 4.41 and 152.31 ± 2.59 respectively at depth 0.00 m (surface), 23.00 ± 1.61, 68.39 ± 3.24 and 191.08 ± 3.11 respectively at depth 0.75 m, 31.52 ± 2.21, 145.37± 4.95 and 375.56 ± 5.50 respectively at 1.50 m and lastly 28.57±1.70, 95.61 ± 3.71 and 181.10 ± 3.94 respectively at 2.25 m depth. The world average activity concentrations for 226Ra, 232Th and 40K are given to be 35 Bqkg-1, 30 Bqkg-1 and 400 Bqkg-1 respectively (UNSCEAR 2000). 232Th showed  higher average values than the world’s average while averages of 226Ra and 40K were lower but most of the activity concentration values obtained in some of the locations are higher than the world’s average values, especially 226Raand 232Th in the soil samples.

Investigation and Comparison of Heat Generated by Coloured Metallic Plates in Response to the Emissive and Absobtion Power of the Surfaces of the Coloured Plate

A colour test was carried out to determine the rates of absorption and emission of infrared radiation by coloured hollowed metallic plates which result in increase in temprature of the holllowed plates at maximum radiation of 750 Wm-2 at Abeokuta 7.198305 and Longitude 3.439533 during the month of March 2013. Five hollow metallic plates of different paint colours (black, green, red, blue and white) were exposed to sunlight simultaneously and the temperature generated in each plate was recorded using a data logger. A wooden box that was divided into five cavities was constructed and lagged with wood shavings to provide insulation and the five coloured hollowed metallic plates of dimension d=4h were inserted in it. The choice dimension d=4h is to minimise shading of the inside of the plate (d is the diameter of each of the plates and h is the height) the top of the plates were covered with a 5 mm thick glass. The top cover plates were securely laid tightly to both the wooden box and the tip of the plates to prevent heat loss to the surrounding and also from crossing from one plate to another.  This arraignment is similar to that of a flat plate collector and calorimeter experiment. The centre of each of the plate was connected to five probes of a data logger and the temperature of changes inside the plates are logged and recorded

Electrocatalytic behaviour of surface confined pentanethio cobalt (II) binuclear phthalocyanines towards the oxidation of 4-chlorophenol

Cobalt binuclear phthalocyanine (CoBiPc) bearing pentanethio substituents at the peripheral positions were synthesized. The immobilization of the synthesized cobalt phthalocyanines on gold electrode was achieved using self-assembled monolayer method (SAM). X-ray photoelectron spectroscopy (XPS) and Kelvin Probe (KP) techniques were used to characterise the formation of monomeric and binuclear phthalocyanine SAMs on the gold surface. The phthalocyanine SAMs on gold electrodes were investigated for electrocatalytic oxidation of 4-chlorophenol. The electrocatalytic properties of tetra- and octa- pentanethio substituted cobalt binuclear phthalocyanine (CoBiPc) are compared with their tetra- and octa-pentanethio substituted phthalocyanine (CoPc). The SAMs modified gold electrode surfaces showed a peak current enhancement and stability and reduction in electrocatalytic potentials compared to the bare or unmodified electrodes towards the detection of the 4-chlorophenol. The SAMs of cobalt binuclear phthalocyanines exhibited more enhanced electrocatalytic properties in terms of stability, detection peak current and reduction of the electrocatalytic over potential
