Abstract: Background Buruli ulcer (BU) is a skin disease caused by Mycobacterium ulcerans. Its exact mode of transmission is not known. Previous studies have identified demographic, socio-economic, health and hygiene as well as environment related risk factors. We investigated whether the same factors pertain in Suhum-Kraboa-Coaltar (SKC) and Akuapem South (AS) Districts in Ghana which previously were not endemic for BU. Methods We conducted a case control study. A case of BU was defined as any person aged 2 years or more who resided in study area (SKC or AS District) diagnosed according to the WHO clinical case definition for BU and matched with age- (+/?5 years), gender-, and community controls. A structured questionnaire on host, demographic, environmental, and behavioural factors was administered to participants. Results A total of 113 cases and 113 community controls were interviewed. Multivariate conditional logistic regression analysis identified presence of wetland in the neighborhood (OR = 3.9, 95% CI = 1.9–8.2), insect bites in water/mud (OR = 5.7, 95% CI = 2.5–13.1), use of adhesive when injured (OR = 2.7, 95% CI = 1.1–6.8), and washing in the Densu river (OR = 2.3, 95% CI = 1.1–4.96) as risk factors associated with BU. Rubbing an injured area with alcohol (OR = 0.21, 95% CI = 0.008–0.57) and wearing long sleeves for farming (OR = 0.29, 95% CI = 0.14–0.62) showed protection against BU. Conclusion This study identified the presence of wetland, insect bites in water, use of adhesive when injured, and washing in the river as risk factors for BU; and covering limbs during farming as well as use of alcohol after insect bites as protective factors against BU in Ghana. Until paths of transmission are unraveled, control strategies in BU endemic areas should focus on these known risk factors.

African Journal of Reproductive Health , 2013,
Abstract: Birth and emergency planning encourages early decision making, helps overcome barriers to skilled maternity care and reduces preventable maternal and newborn deaths. A facility based postnatal survey of 483 childbearing women in Accra, Ghana determined birth and emergency planning steps, awareness of obstetric danger signs, reported maternal and newborn complications and birth outcome based on length of hospital stay. Supervised antenatal care and delivery were nearly universal. Overall, 62% had a birth plan, 74% had adequate knowledge of danger signs, while 64% and 37% reported maternal and newborn complications respectively. Accompaniment by a birth companion and saving money were considered the most useful planning steps. Knowledge of danger signs was associated with birth and emergency planning, and birth and emergency planning was associated with reported birth outcome. Birth and emergency planning as a critical component of antenatal care can influence birth outcomes and should be extended to all pregnant women. Résumé La planification des naissances et d'urgence encourage la prise de décision rapide, aide à surmonter les obstacles aux soins de maternité qualifiés et réduit les décès maternels et néonatals évitables. Une enquête post-natale qui a été basée sur l’établissement, et auprès des 483 femmes en age de procréer à Accra, au Ghana a déterminé les étapes de planification des naissances et d'urgence, la sensibilisation des signes de danger obstétrical, a rapporté des complications maternelles et néonatales et les résultats des naissances selon la durée du séjour à l'h pital. Les soins prénatals et l'accouchement surveillés étaient presque universels. Dans l'ensemble, 62% avaient un plan de naissance, 74% avaient une connaissance adéquate des signes de danger, tandis que 64% et 37% ont déclaré des complications maternelles et néonatales, respectivement. Le fait d’être accompagné par un compagnon de naissance et d’économiser de l'argent ont été considérés comme les étapes de planification les plus utiles. La connaissance des signes de danger a été associée à la naissance et à la planification d'urgence et la planification des naissances et d'urgence a été associée à des résultats des naissances déclarées. La planification des naissances et d'urgence comme un élément essentiel des soins prénatals peuvent influer sur les résultats de grossesses et devrait être mis a la portée de toutes les femmes enceintes.
Imaging and Dosimetric Consideration for Titanium Prosthesis Implanted within the Irradiated Region by Cobalt-60 Teletherapy Unit  [PDF]

International Journal of Medical Physics,Clinical Engineering and Radiation Oncology (IJMPCERO) , 2018, DOI: 10.4236/ijmpcero.2018.72014
Abstract: The aim of this research is to observe dose distributions in the vicinity of titanium prosthetic implants during radiotherapy procedures on 60Co teletherapy machine, Prowess Panther treatment planning system (TPS). Data were obtained using a locally fabricated tissue equivalent phantom CT images with titanium prosthesis which was irradiated with 60Co gamma radiation. Prowess TPS (1.25 MeV) estimated less variations. Proximal ends of the metal recorded slight increase in doses as a result of backscatter with dose increment below acceptable tolerance of ±3%. Doses measured decreases on the distal side of the prosthesis at a distance less than dmax from the plate on each beam energy. The depth dose increases marginally after a certain depth level which generally originated from the unperturbed dose due to increase in the electron fluence. The percentage of depth doses decrease with the increase in plate thickness. A reduction in the above trend was also noticed with an increase in beam energy primarily because scattered photons are more forwardly directed. Prowess TPS (convolution superposition algorithm) was found to be better at reducing dose variation when correction for artifact. Manual calculations on blue phantom data agree with results from Prowess. This treatment system is capable of simulating dose around titanium prosthesis as its range of densities, 0.00121 to 2.83, excludes titanium density (rED for titanium is 3.74).

Abstract: Background HAART is anticipated to result in an increase in long-term survival, but may present with the development of associated complications. The aim of this study was to assess the renal function of HIV-infected patients on antiretroviral therapy. Methods A case-control study (January to May 2013) conducted at the Suntreso Government Hospital, Kumasi, Ghana. A total of 163 HIV-infected patients (mean age 39.9±10.22) were studied, of which 111 were on HAART (HIV-HAART) and 52 were not (HIV-Controls). Serum urea, creatinine, potassium, sodium, chloride and CD4 counts were measured with the determination of eGFR (CKD-EPI and MDRD). Data was analysed using GraphPad Prism. The Chi-square, t-test, one-way ANOVA and Spearman's correlation were used. P values <0.05 were considered significant. Results Mean CD4 count of HIV-Controls was higher than that of HIV-HAART but was not significant (p = 0.304). But for sodium levels which were higher in HIV-Controls (p = 0.0284), urea (p = 0.1209), creatinine (p = 0.7155), potassium (p = 0.454) and chloride (p = 0.6282) levels did not differ significantly between both groups. All serum biochemical parameters did not differ significantly, irrespective of duration on therapy and CD4 counts. Based on regimen, sodium, chloride, urea and creatinine did not differ significantly between TDF, EVF and NVP-based therapies. Prevalence of CKD (eGFR <60 ml/min/1.73 m2) in the total population was 9.9% and 3.7% with the MDRD and EPI-CKD equations respectively. Conclusions Renal insufficiency remains prevalent in HIV patients. Changes in renal function occur in HIV infection and over the course of HAART but the difference at either stage is not significant. This suggests the role of HIV infection, HAART and the presence of traditional risk factors but not HAART in itself, in renal dysfunction. We however recommend a close monitoring of patients before and during HAART, to aid in evaluating drug combinations and implement dose modifications when necessary.

Abstract:

Objectives: To define clinical differences in the acute phase response and serum acute phase reactants between gout, pseudogout and crystal-induced arthritis in the presence of non-articular infections (CAI). Patients and Methods: Eleven patients with definite gout, 12 patients with pseudogout and 5 patients with CIA were included in the study. Results: The erythrocyte sedimentation rate (ESR) was significantly different between gout (68.2 ± 49.9 mm/Hr) and CIA (113.8 ± 37.2 mm/Hr) but not between gout and pseudogout (83.9 ± 45.6 mm/Hr) or between pseudogout and CIA. The C-reactive protein (CRP) was significantly increased between gout (10.1 ± 7.9 mg/dL) and pseudogout (18.9 ± 9.8 mg/dL), gout and CIA (36.5 ± 12.4 mg/dL) as well as between pseudogout and CIA. The peripheral white cell count was significantly different between gout (9.27 ± 3.7 k/μL) and CIA (16.5 ± 6.8 k/μL), and between pseudogout (8.9 ± 3.2 k/μL) and CIA. Conclusions: Measurement of ESR and CRP are helpful in crystal-induced arthritis. The CRP has more discriminating utility than the ESR in distinguishing between gout, pseudogout and CIA. Peripheral wbc is most useful for differentiating crystal-induced arthritis from CIA.

Transmetatarsal Amputation: A Case Series and Review of the Literature

Journal of Aging Research , 2012, DOI: 10.1155/2012/797218
Abstract: Foot ulceration is a major cause of morbidity amongst patients with diabetes. In severe cases of ulceration, osteomyelitis and amputation can ensue. A distinct lack of agreement exists on the most appropriate level of amputation in cases of severe foot ulceration/infection to provide predictable healing rates. This paper provides an overview of the transmetatarsal amputation (TMA) as a limb salvage procedure and is written with the perspective and experiences of the Department of Podiatric Surgery at West Middlesex University Hospital (WMUH). We have reflected on the cases of 11 patients (12?feet) and have found the TMA to be an effective procedure in the management of cases of severe forefoot ulceration and infection. 1. Introduction In recent times, increased attention has been placed on the alarming increase in the incidence of diabetes. Diabetic foot ulcers occur in up to 15% of diabetic patients [1], and amputation rates amongst this population have been documented as 11% [2]. In particular cases of severe foot infection, amputation should not necessarily be looked upon as failure of care, but rather the most appropriate intervention for preventing more proximal spread and persistent hospital attendance. Aggressive management of severe foot infection/ulceration can reduce the risk of proximal amputation. 2. Transmetatarsal Amputation A proportion of the diabetic community experience serious and debilitating complications associated with their feet, with a 12–25% increased risk of developing foot ulceration [3]. Development of diabetic foot ulceration is often a multifactorial process; however, the presence of influences such as neuropathy and peripheral vascular disease is recognised as significant contributing factor. The neuroischaemic ulceration accounts for 90% of those encountered in the diabetic population [4], and approximately half of diabetic foot wounds develop an infection, the majority involving only soft tissue [5]. In circumstances where soft tissue infection is severe or where underlying bone is infected, amputation may be considered an appropriate line of treatment. Mills et al. [6] recognised that infection and gangrene due to microvascular disease were two major factors that resulted in failure of wound healing, resulting in amputation. At WMUH, a treatment pathway has been developed for patients with severe foot ulceration/infection who have been deemed suitable candidates for undergoing TMA (see Assessment and Treatment below). Patients are urgently admitted into the hospital and are assessed by the medical and surgical teams,
The double-edged sword: financial source of household healthcare expenditure in Ghana
Henry Armah Tagoe
Journal of Public Health in Africa , 2012, DOI: 10.4081/jphia.2012.e17
Abstract: In many regions, some of the most formidable enemies of health are joining forces with the allies of poverty to impose a double burden of disease, disability and premature death. This paper looks at the main financial sources households use to finance healthcare in Ghana. It examines the spatial and socio-economic dynamics and the challenges these pose to health and development. Analysis of the 2003 Ghana World Health Survey data indicates that approximately 41% of households depend on more than one financial source with 88% depending on household income to finance healthcare expenditure. The high dependency on household income will erode gains in the economic and health sector in the midst of the recent global economic recession. Comprehensive national health insurance programs that cover emerging disease conditions will mitigate the double burden of disease on households in emerging economies.

Journal of Building Construction and Planning Research (JBCPR) , 2018, DOI: 10.4236/jbcpr.2018.64019
Abstract: Selecting a contractor for construction project is a difficult decision to be taken by a client because it may lead to construction delivery problems or successful delivery of the project. This study, therefore, investigated the contractor selection criteria in the Ghanaian construction industry, considering the benefits and challenges. A quantitative research method was adopted in this study through the use of a questionnaire. The target population for the study consisted of registered contractors and consultants in the Ashanti and Brong-Ahafo regions of Ghana. It was found that though the construction professionals are well vested with the prequalification selection criteria that are being used within the Ghanaian construction industry, they were not familiar with multi-criterial section methods. It was also found that the benefits of the contractor selection criteria include: enabling the client to select contractors who are performers for the project, saving the project owner a lot of time, minimizing the possibility of contractor default, and facilitating the achievement of project success and the objectives within the scheduled time. Furthermore, excessive cost and time overrun, poor quality standard, imprecise assessments due to lack of information, criteria being very complex and difficult to apply in practice, among others were identified as the challenges to the contractor selection criteria in Ghanaian construction industry. The study recommends for further studies to determine the impact of the identified challenges on construction projects, and ways to minimize the challenges.

Abstract: Extraction of Limestone is an economically important and widespread activity in Ghana and has existed since historical times. However, in spite of its remarkable contribution towards economic development, some adverse impacts have been noticed, especially where extraction is carried out without proper planning and use of modern technology and scientific methods. We have carried out an assessment on the environmental effects of limestone quarrying on some communities in the Lower Manya Krobo District in the Eastern region of Ghana. Dust emission is one of the major effects of the practice of limestone extraction and as such, dust (PM10) sampling was conducted at the affected communities. Mean dry season results recorded in these communities stand at 125.0 μg/m3 or Bueryonye, 116.0 μg/m3 at Odugblase and 109.3 μg/m3 at Klo-Begoro. Oterkpolu community which served as the control recorded an average of 50.5 μg/m3. Average rainy season values recorded for the communities were 83.3 μg/m3 for Bueryonye, 113.1 μg/m3 at Odugblase and 74.4 μg/m3 at Klo-Begoro. The control community, Oterkpolu, had 43.3 μg/m3. These values are above the EPA, Ghana daily guideline level of 70 μg/m3 over a time-weighted average per 24 hours. Questionnaires administration and health records obtained from the health facilities in the communities revealed notable deteriorations in the health of the people as a result of the quarrying activities in the area. Notable among these is the prevalence of malaria though not related to dust emissions, it results from mosquitoes breeding in the stagnant pools of water found in pits created as a result of the mining activity. Other common health cases recorded were acute respiratory tract infection, ear and eye infections, cough and pneumonia.
