The incidence of Tuberculosis (TB) differs among countries and contributes to morbidity and mortality especially in the developing countries. Trends and seasonal changes in the number of patients presenting with TB have been studied worldwide including sub-Saharan Africa. However, these changes are unknown at the Korle-Bu Teaching Hospital (KBTH). The aim of this study was to obtain a time series model to estimate the incidence of TB cases at the chest clinic of the Korle-Bu Teaching hospital. A time series analysis using a Box-Jenkins approach propounded as an autoregressive moving average (ARIMA) was conducted on the monthly TB cases reported at the KBTH from 2008 to 2017. Various models were stated and compared and the best was found to be based on the Akaike Information Criterion and Bayesian Information Criterion. There was no evidence of obvious increasing or decreasing trend in the TB data. The log-transformed of the data achieved stationarity with fairly stable variations around the mean of the series. ARIMA (1, 0, 1) or ARMA (1,1) was obtained as the best model. The monthly forecasted values of the best model ranged from 53 to 55 for the year 2018; however, the best model does not always produce the best results with respect to the mean absolute and mean square errors. Irregular fluctuations were observed in the 10 -year data studied. The model equation to estimate the expected monthly TB cases at KBTH produced an AR coefficient of 0.971 plus an MA coefficient of − 0.826 with a constant value of 4.127. The result is important for developing a hypothesis to explain the dynamics of TB occurrence so as to outline prevention programmes, optimal use of resources and effective service delivery.

Background: Anaesthesia has always been misconstrued as a ‘behind the scenes’ specialty. Despite advancements in anaesthesia, there is inadequate public knowledge regarding the specialty, the scope of the functions of anaesthetists, and the pivotal role anaesthetists play in the healthcare delivery system. This study therefore assessed the knowledge and perception of anaesthesia and the role of anaesthetists among patients in a tertiary healthcare facility. Methods: A cross-sectional study was conducted over 3 months in 2015 among 279 patients accessing services at the pre-anaesthetic clinic of the Korle-Bu Teaching Hospital. Patients were interviewed using a structured questionnaire assessing socio-demographic characteristics, their knowledge and perceptions about anaesthesia, and the role of anaesthetists. Results: The majority of patients (62.4%) had heard about anaesthesia. Most (85%) knew that specially trained doctors or nurses were responsible for the delivery of anaesthesia. Nearly half the patients indicated anaesthesia was all about ‘putting people to sleep and waking them up’. Less than 15% of patients had knowledge of the role of anaesthetists outside the confines of the operating theatre suites. Conclusion: A considerable number of patients had heard about anaesthesia and knew the people responsible for the delivery of anaesthesia. The perception of most patients is that anaesthesia is all about ‘putting patients to sleep and waking them up’. There was poor knowledge of patients regarding the role of anaesthetists beyond the confines of the operating theatre.

Pregnancy is associated with significant changes in maternal cardiovascular system which regulates oxygen and nutrient supply to the growing foetus. Nitric oxide, a physiologic vascular smooth muscle relaxant regulates blood flow and therefore may play a role in the cardiovascular changes in pregnancy. The study aimed to determine the levels and changes in maternal serum nitric oxide levels during healthy pregnancy. A case-control study was conducted among 32 healthy non-pregnant women as controls and 100 healthy pregnant women (consisting of 33 first trimester, 37 s trimester, and 30 third trimester) as cases. Subjects were consecutively recruited into the study after obtaining an informed consent and meeting the inclusion criteria. Griess Reagent method was used to determine serum nitric oxide levels. There were no statistically significant difference in the ages and parity of recruited cases and controls. Mean arterial blood pressures were significantly lower (p = 0.009) and serum nitric oxide levels were significantly higher (p < 0.001) in healthy pregnant women compared to healthy non-pregnant women. There was a non-significant progressive increase in serum nitric oxide levels during healthy normal pregnancy. The finding of a significantly reduced blood pressures and a significant increase in serum nitric oxide levels in healthy pregnancy may suggest a role of nitric oxide in vascular adaptation in pregnancy.

BACKGROUND: Pregnancy is described as a normal physiologic state associated with various biochemical changes. Magnesium and calcium are essential macronutrients required for foetal growth. Complications associated with their deficiency during normal pregnancy include; low neonatal birth weight, pre-eclampsia, eclampsia and preterm labour. Changes in serum levels of magnesium and calcium in normal pregnancy have not been extensively studied among Ghanaian women. AIM: To determine the variation in serum magnesium and calcium levels with gestational age in normal pregnancy in Ghanaian women. METHODS: A hospital-based comparative cross-sectional study was conducted among 32 normal non-pregnant women (Group A) and 100 normal pregnant women (Group B) attending the clinic at the Korle-Bu Teaching hospital. The group B pregnant women were further divided into Group B1 (n = 33), Group B2 (n = 37) and Group B3 (n = 30) based on their pregnancy gestation as first, second and third trimester respectively. Blood samples were obtained from the antecubital vein of subjects and total serum calcium, magnesium, protein and albumin were estimated. Data obtained were analysed using SPSS for windows version 20. Analysis of variance (ANOVA) was employed to determine the statistical differences between the groups. A p-value of ≤ 0.05 was considered significant. RESULTS: Mean serum total calcium and magnesium in first, second and third trimester normal pregnant women were 2.14 ± 0.16, 2.13 ± 0.44, 2.13 ± 0.35 mmol/L and 0.77 ± 0.11, 0.77 ± 0.16 and 0.76 ± 0.14 mmol/L respectively. Mean serum total calcium and magnesium levels in non-pregnant women were 2.20 ± 0.16 and 0.80 ± 0.10 mmol/L respectively. There was a statistically non-significant difference in serum total calcium and magnesium between non-pregnant and normal pregnant women, with p-values of 0.779 and 0.566 respectively. Mean total serum protein and albumin in first, second and third-trimester normal pregnant women were 68.42 ± 10.37, 70.46 ± 6.84, 66.70 ± 7.83 g/L and 39.92 ± 3.22, 40.75 ± 8.06, 38.26 ± 3.02 g/L respectively. Mean total serum protein and albumin in non-pregnant women were 73.13 ± 7.02 and 42.94 ± 3.03 g/L respectively. Mean total serum protein and albumin levels were lower in pregnant women as compared to non-pregnant women with the difference being significant in the third trimester (p-values of 0.012 and 0.002). CONCLUSION: Total serum calcium and magnesium levels in normal pregnancy were non-significantly lower compared to non-pregnant women in Ghana. There was a reduction in total serum protein, and albumin levels during pregnancy with a significant reduction noticed during the third trimester compared to the non-pregnant state.

Background: Specialisation is perceived as essential for success, and affects the availability and distribution of medical personnel and the quality of service the health system is able to deliver. In Ghana, some areas of medical specialties have a relatively good number of practitioners and are constantly attracting prospective doctors into these fields. Anaesthesia, which is an essential and integral part of the health care system, is one field with an inadequate workforce and has been attracting few doctors into the specialty. Method: A cross-sectional study was conducted among 183 undergraduate final-year students of the University of Ghana School of Medicine and Dentistry. A total of 183 self-reporting questionnaires were distributed among the students during tutorials for their final exams. Of these, 146 questionnaires were completed and returned. Results: General surgery was the most desirable specialty 26 (17.8%), paediatrics was the second most desirable specialty 24 (16.4%), whilst anaesthesia 2 (1.4%) ranked seventh. Conclusions: The results of this survey suggest that duration of exposure during clinical clerkship influences career decision among undergraduate medical students. Most of the students prioritise their choice of specialty based on interest and exposure during rotation through the specialty.
