Signature: ………………………… Date: …………................... i www.udsspace.uds.edu.gh ABSTRACT Snakebite poisoning is a public health concern to persons in agrarian environments and the northern region of Ghana is no exception. Youthful male agricultural and field workers have been reported to be at higher risk of snakebite, hence necessitating a study to determine the full extent of the snakebite problem in the Tamale Teaching Hospital. The objective of this study was to determine the epidemiological characteristics of the snakebite cases that were reported at the Tamale Teaching Hospital. A retrospective review of snakebite cases reported to the Tamale Teaching Hospital between January, 2013 and June, 2014 was carried out. A total of 150 cases were reviewed and the data analysed using SPSS version 20 with all chart drawn using Microsoft Excel 2013. The results of the study were, the prevalence of snakebite cases reported at the hospital was 89/100,000 population. Majority of the victims were between 15-59 years (65%). Males (64.7%) were the majority with farmers (46%) being the most affected. The majority of cases occurred in February, March and September mostly from the rural areas with the East Gonja district having the highest. The lower limbs were the commonly bitten site with most occurring during the daytime (68.67%) and outdoors (75.33%). Pain, swelling and bleeding were the commonest clinical presentations of the victims whiles 68.67% of them used first aid. The carpet viper was the only positively identified snake. Of the 78.67% of the victims who received ASV, 6.78% adversely reacted. The outcome of the cases were 84% cured, 12% discharged against medical advice and 4% dead. In conclusion, snakebite prevalence is high at the TTH, affecting mainly young agricultural male workers in the rural parts of the region. The carpet viper is responsible for most bites and ASV administration was the mainstay of snakebite management. ii www.udsspace.uds.edu.gh ACKNOWLEDGEMENTS My profound gratitude goes first of all to the Almighty God for His magnificent providence and protection throughout this work.

  • Addressing the Causes and Consequences of the Farmer-Herder Conflict in Ghana [ Margaret Adomako]
    KOFI ANNAN INTERNATIONAL PEACEKEEPING TRAINING CENTRE POLICY BRIEF 6 | September 2019 Addressing the Causes and Consequences of the Farmer-Herder Conflict in Ghana [ Margaret Adomako] SUMMARY For several years, tensions have existed between local farmers and Fulani herdsmen in Ghana. However, various factors have recently, contributed to the tensions taking on a violent nature and becoming one of Ghana’s foremost security threats. Based on an extensive fieldwork conducted in 2016/2017, this policy brief discusses the causes of the Farmer-herder conflict and its consequences on the security, social and economic structures of the country. It looks at the shortfalls of Operation Cowleg, the major intervention that has been implemented by the state and concludes with a few policy relevant recommendations which includes a nationwide registration of herdsmen to support the government in the implementation of an effective taxation system. INTRODUCTION night grazing. The Asante Akyem North district of Ghana has Beginning from the late 1990s, the farmer-herder conflict has recorded various cases of this nature as a result of its lush become a recurring annual challenge for the Government vegetation. The district has a wet semi-equatorial climate with of Ghana. This conflict usually occurs between local farmers annual total rainfall between 125cm and 175cm making it a and herdsmen, mostly of the Fulani origin, over grazing lands favorite spot for crop farming2 and animal grazing especially and water sources in certain parts of Ghana. The conflict has in the dry season.3 Usually, during the dry season, herders been prevalent in Agogo, in the Ashanti region, and Afram from towns such as Donkorkrom and Ekyiamanfrom pass Plains in the Eastern region, although there have also been through Agogo on their way to Kumawu and Nyantakurom in recorded incidences in some parts of the Northern and Brong search of pasture during the dry season.

  • Epidemiology of Snakebites from a General Hospital in Singapore: a 5-Year Retrospective Review (2004-2008) 1 Hock Heng Tan, MBBS, FRCS A&E (Edin), FAMS
    640 Epidemiology of Snakebites—Hock Heng Tan Original Article Epidemiology of Snakebites from A General Hospital in Singapore: A 5-year Retrospective Review (2004-2008) 1 Hock Heng Tan, MBBS, FRCS A&E (Edin), FAMS Abstract Introduction: This is a retrospective study on the epidemiology of snakebites that were presented to an emergency department (ED) between 2004 and 2008. Materials and Methods: Snakebite cases were identified from International Classification of Diseases (ICD) code E905 and E906, as well as cases referred for eye injury from snake spit and records of antivenom use. Results: Fifty-two cases were identified: 13 patients witnessed the snake biting or spitting at them, 22 patients had fang marks and/or clinical features of envenomations and a snake was seen and the remaining 17 patients did not see any snake but had fang marks suggestive of snakebite. Most of the patients were young (mean age 33) and male (83%). The three most commonly identified snakes were cobras (7), pythons (4) and vipers (3). One third of cases occurred during work. Half of the bites were on the upper limbs and about half were on the lower limbs. One patient was spat in the eye by a cobra. Most of the patients (83%) arrived at the ED within 4 hours of the bite. Pain and swelling were the most common presentations. There were no significant systemic effects reported. Two patients had infection and 5 patients had elevated creatine kinase (>600U/L). Two thirds of the patients were admitted. One patient received antivenom therapy and 5 patients had some form of surgical intervention, of which 2 had residual disability.

An exploration of the views of some selected households Jones Lewis Arthur International Relations and Institutional Linkage Directorate, Sunyani Technical University, P. O. Box 206, Sunyani-Ghana. Received 24 July, 2017; Accepted 22 September, 2017 This paper explores the perceptions of families and households near Bui National Park, on the impact of Bui dam on their capital assets and how they navigate their livelihoods through the impacts of Bui Dam construction. The mixed methods approach was applied to sample views of respondents from thirteen communities of which eight have resettled as a result of the Bui Dam construction. In-depth interviews were conducted with 22 key informants including four families to assess the impacts of Bui Dam on community capital assets and how these communities near Bui Dam navigate their livelihoods through the effects of the dam construction, and whether the perceived effects of the Bui Dam differed for families in the different communities who were impacted by the dam construction. The results of the study showed that the government failed to actively integrate policies and programmes that could build on the capacity of communities to navigate their livelihoods through the effects of Bui Dam construction and associated resettlement process. Also, dam construction can have both positive and negative impacts on the livelihood opportunities of nearby communities.

  • Brong Ahafo Region
    REGIONAL ANALYTICAL REPORT BRONG AHAFO REGION Ghana Statistical Service June, 2013 Copyright © 2013 Ghana Statistical Service Prepared by: Martin Kwasi Poku Omar Seidu Clara Korkor Fayorsey Edited by: Kwabena Anaman Chief Editor: Tom K.B. Kumekpor ii PREFACE AND ACKNOWLEDGEMENT There cannot be any meaningful developmental activity without taking into account the characteristics of the population for whom the activity is targeted. The size of the population and its spatial distribution, growth and change over time, and socio-economic characteristics are all important in development planning. The Kilimanjaro Programme of Action on Population adopted by African countries in 1984 stressed the need for population to be considered as a key factor in the formulation of development strategies and plans. A population census is the most important source of data on the population in a country. It provides information on the size, composition, growth and distribution of the population at the national and sub-national levels. Data from the 2010 Population and Housing Census (PHC) will serve as reference for equitable distribution of resources, government services and the allocation of government funds among various regions and districts for education, health and other social services. The Ghana Statistical Service (GSS) is delighted to provide data users with an analytical report on the 2010 PHC at the regional level to facilitate planning and decision-making. This follows the publication of the National Analytical Report in May, 2013 which contained information on the 2010 PHC at the national level with regional comparisons. Conclusions and recommendations from these reports are expected to serve as a basis for improving the quality of life of Ghanaians through evidence-based policy formulation, planning, monitoring and evaluation of developmental goals and intervention programs.

While the western branch of the Diakhanke in Senegambia and Guinea has received much attention from researchers2, the southern branch of mori lineages with their imamates extending from Dia/Djenne up the river Bani and its branches have been almost ignored. It has established centres of learning along the major southern trade routes and in the Sassandra- Bandama-Comoë-Volta river basins up to the Akan frontier3. The Kamaghate imamate has been established with the Gonja in the Volta basin but can be traced back to the Jula/Soninke of Begho, Kong, Samatiguila, Odienne and ultimately to the region of Djenne and Dia.

University of Sri Jayawardenepura, Sri Lanka 10. Utah State University, USA ’Presenting author’s e-mail: [email protected] An Asian natricine snake, Rhabdophis tigrinus, has a unique series of organs, called nuchal glands, which contain cardiac steroidal toxins known as Bufadienolides. Rhabdophis tigrinus sequesters Bufadienolides from its toad prey and stores them in the nuchal glands as a defensive suBstance. Among more than 3400 species of snakes, only 18 Asian natricine species are known to have the nuchal glands. These 18 species Belong to three genera, Balanophis, Macropisthodon, and Rhabdophis. In Macropisthodon and Rhabdophis, however, species without the nuchal glands also exist. This evidence suggests multiple independent origin and/or secondarily loss of the nuchal glands. To infer the evolutionary history of the nuchal glands, we investigated the molecular phylogenetic relationships among Eurasian natricine species with and without the nuchal glands, Based on variations in partial sequences of the oocyte maturation factor Mos (c-mos) gene, the recomBination-activating gene 1 (Rag 1), and the mitochondrial cytochrome B (cyt.B) gene (total 2.6 kBp).
