The worsening humanitarian situation in Angola and the great lakes due to protracted wars, led to an influx of refugees in Namibia since 1992. The peak of the influx was between 1999-2002 when the camp population reached 25,000 people. Among the many challenges faced by these refugees was their health and nutrition. Malnutrition accounted for high levels of morbidity and mortality among the refugees. This study covered a review of health and nutritional situation of children less than five years of age in Osire refugee camp. It proposed that prevalence of malnutrition among this age group is a proxy for the nutritional status of the refugee population. It also considered the factors prevalent in the camp that affect the nutrition of the children.

Dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic, Durban University of Technology, 2009. / The Effect of Cervical and Thoracic Spinal Manipulations on Blood Pressure in Normotensive Males. BACKGROUND A distinguishing feature of chiropractic is manipulation that is a load delivered by hand, to specific tissues (usually a short lever bony prominence) with therapeutic intent. Chiropractic spinal manipulation results in somatovisceral reflexes, which can affect the cardiovascular system and thereby reduce blood pressure. Areas of the spine known to cause such effects are the upper cervical region and the upper thoracic region. Increased blood pressure/hypertension is a global disorder. The incidence is increasing and leads to complications of cardiovasular disease and cerebral vascular accidents OBJECTIVES The objectives of the study were to determine whether spinal manipulation evokes somatovisceral reflexes and causes a reduction in blood pressure following an atlanto-axial (C0/C1), and Thoracic segments one to five manipulations (T1-T5). METHODS Forty, asymptomatic, normotensive males between the ages of 20 – 35 years of age participated in the study. All subjects underwent four consecutive days of intervention. Day one was sham laser. Day two was C0/C1 spinal manipulation. Day three was T1-T5 thoracic manipulation. Day four was a combination of C0/C1 and T1-T5 spinal manipulations. RESULTS The results of this study suggest that blood pressure decreases following a cervical or a thoracic manipulation, however a combination of the manipulations does not have a significant cumulative effect on the reduction of blood pressure. iv CONCLUSIONS Somatovisceral reflexes are evoked following a spinal manipulation, causing a reduction in blood pressure after an upper cervical or upper thoracic manipulation. Neurophysiological effects occurring as a result of spinal manipulation may inhibit or excite somatosomatic reflexes, which changes heart rate and blood pressure.

Geohelminthiasis is a serious problem in city slums and despite being easily treatable in the short term, its elimination enjoys a low priority by parents, teachers and public health authorities. This is partly due to the greater emphasis given to the AIDS and TB programmes. This study of the prevalence, intensity, and reinfection rates of single and multiple geohelminth (Ascaris lumbricoides, Trichuris trichiura and Necator americanus) infections in young children living in slums (informal settlements) in the Durban Unicity is a first for an African city and one of few similar studies anywhere in the world. The geohelminth status was assessed by means of a baseline survey of ten different slums, followed by two further surveys, one after 4Y:z - 6 months and another after 12 months. Infections were measured by microscopic examination of faeces before and after chemotherapy, and risk factors within and between slums were identified by means of a quantifiable questionnaire. The study showed that: 1. The slums have a high endemicity and transmission rate of geohelminth infections. 2. The sub-tropical climate and environment ensured a high survival rate of infective stages. 3. A. lumbricoides had a high prevalence and intensity, followed by T. trichiura with a moderately high prevalence and light intensity. A small proportion of children had intensities of these helminths an order of magnitude higher than previously recorded from rural areas of South Africa. N americanus had a very low prevalence and a very light intensity. 4. Egg output from follow-up 1 to follow-up 2 increased 4.6 fold for A. lumbricoides and 9.4 fold for T. trichiura. 5. Albendazole proved to be a very effective drug against A. lumbricoides and N americanus but not as effective against T. trichiura. 6. The infection and reinfection rates of A. lumbricoides and T. trichiura proved to be influenced by different risk factors. 7. The most important risk factors included topographical position of the slum, quality of the dwelling, number of inhabitants, geophagy and source of fruit and vegetables. II Whereas the ideal solution to the geohelminth problem in the slums would be to upgrade the slum and its inhabitants, this is not an immediately viable option. The challenge of geohelminth control in these slums must be to determine the degree of environmental contamination by human faeces containing infective eggs, to ascertain the survival rate of the eggs and larvae and to implement a control programme together with suitable education of the inhabitants. The Parasite Control Programme should take into consideration that many slum-dwelling children do not go to school and need to be treated at home. A further factor that will have to be taken into account is that lack of influx control to urban areas will mean the continual reinfection of slum-dwellers by the movement from the rural areas. / Thesis (Ph.D.)-University of Natal, Durban, 2001.

Through an analysis of Cree concepts of well-being, I challenge conventional social scientific definitions of health. In this dissertation I argue that there exists a fundamental biomedical dualism in health studies and, using cross-cultural examples, explore an expanded notion of "health". I then introduce the Cree concept of miyupimaatisiiu ("being alive well") and explain that for the Whapmagoostui Cree there is no term that translates back into English as health. I present the core symbols of "being alive well" and in their analysis find a persistence of traditional meanings. For the Cree "being alive well" is consonant with "being Cree", simultaneously transcending the individual and reflecting current political realities. Miyupimaatisiiu for the adult Cree of Whapmagoostui is a strategy of cultural assertion and resistance and hence situated within the realm of political discourses.
