A neuropsychological rehabilitation service delivery model for South African adults with acquired brain injury (RSDM-SA).

In low- and- middle- income countries (LMICs) such as South Africa, a high number of Acquired Brain Injuries (ABIs) and a lack of accessibility to healthcare lead to many survivors of brain injury not receiving the level of healthcare and rehabilitation required. Further, in LMICs life-saving or acute care is prioritized with an inadequate focus on the lifelong effects of ABI. This study used Program Theory to develop a Rehabilitation Service Delivery Model for South African Adults with Acquired Brain Injury (RSDM-SA) that caters for the unique nuances of a resource-constrained and culturally diverse context.

South African professional Super Rugby players' lived experiences of career-related traumatic injuries: A descriptive phenomenological analysis.

Background: Historically, non-career-ending traumatic rugby injury (TRI) has been viewed from a predominantly biological perspective. However, dimensional perspectives, such as the biopsychosocial model, have highlighted the need to incorporate psychosocial understandings of TRI into treatment plans.

Aim: To describe the lived experiences of a cohort of traumatically injured South African Super Rugby players in order to add to the body of literature on the subject of TRI experience.

The toxicology of Amanita virosa: the destroying angel.

This paper examines the biology and medical consequences of ingesting the potentially lethal poisonous mushroom, Amanita virosa, the Destroying Angel. The fungus, its structure, distribution and toxic components are described. Symptoms of human poisoning by A.

Multicentric T-cell lymphoma associated with feline leukemia virus infection in a captive namibian cheetah (Acinonyx jubatus).

This case report describes a multicentric lymphoma in a 4 yr old female wildborn captive cheetah (Acinonyx jubatus) in Namibia after being housed in an enclosure adjacent to a feline leukemia virus (FeLV) infected cheetah that had previously been in contact with domestic cats. The year prior to the onset of clinical signs, the wild-born cheetah was FeLV antigen negative. The cheetah subsequently developed lymphoma, was found to be infected with FeLV, and then rapidly deteriorated and died.

The toxicology of Amanita phalloides.

This paper examines the biology and medical consequences of ingesting the potential lethal poisonous mushroom, Amanita phalloides, the Death Cap. The organism is a fungus, its structure, distribution and toxic components are described. Symptoms of human poisoning by Am.

Streptococcus phocae infections associated with starvation in Cape fur seals.

Mortalities and abortions associated with starvation occurred at Cape Cross, Namibia, in Cape fur seals (Arctocephalus pusillus pusillus). Affected seals showed lethargy and emaciation, and the most common pathological signs were those of a respiratory infection, both in adults and offspring. Streptococcus phocae was isolated from adult seals, a cub and aborted foetuses.

Experimental studies with Stronglyloides papillosus in goats.

Unusual clinical and pathological observations in the field in goats and sheep suffering from Strongyloides papillosus infection prompted experimental work on this parasite. Goats were infected percutaneously with either single or multiple, low or high levels of S. papillosus.

The usefulness of faecal phosphorus and nitrogen in interpreting differences in live-mass gain and the response to P supplementation in grazing cattle in arid regions.

The average daily gains of heifers and oxen on commercial and experimental farms in Namibia were used to indicate production differences in several areas and at different rates of phosphorus and protein supplementation. Faecal concentrations of phosphorus and nitrogen were used to indicate concentrations of these nutrients in grazing. Areas with high concentrations of nitrogen in faeces proved to support high levels of average daily gain.

[Adaptation of the Health Belief Model for the prevention of HIV infection].

The spreading of AIDS in the RSA occurs mainly through sexual transmittance, therefore people that divulge in high risk behaviour must be motivated to change their behaviour to such an extend that they won't expose themselves as well as other people to HIV infection. An AIDS tragedy in SA can only be averted by preventing HIV infection. That can only occur by changing HIV risk behaviour.

Association of luminous bacteria with artificial and natural surfaces in arabian gulf seawater.

Luminous bacteria in seawater around the islands of Bahrain are predominantly Vibrio harveyi and have the capability to adhere to artificial fibrous surfaces. Phytoplankton did not appear to have any specific relationship with luminous bacteria, but macroalgae were shown to possess an enhanced concentration of luminous bacteria.

Cardiomyopathy caused by avocado (Persea americana Mill) leaves.

Six of 21 goats feeding on fresh avocado (Persea americana) leaves from pruned trees, showed clinical signs of cardiac distress. Some sheep subsequently dosed experimentally at different dosage rates with the same and other avocado varieties, showed clinical signs of respiratory or cardiac distress and myocardial lesions at autopsy.

An outbreak of contagious bovine pleuropneumonia in the Owambo Mangetti area of South West Africa/Namibia: microbiological, immunofluorescent, pathological and serological findings.

An outbreak of contagious bovine pleuropneumonia (CBPP) in the Owambo Mangetti area of South West Africa/Namibia in 1982 led to the slaughter of 3,153 cattle. The lungs of 266 of these animals were scrutinized for gross lesions of CBPP and samples of lung tissue, sequestral contents or pleural fluid were submitted to the Veterinary Research Institute (VRI), Onderstepoort for microbiological, immunofluorescent and pathological examination. Immunofluorescence proved to be the most successful method of diagnosis producing 96% of positives, while mycoplasma isolations were only positive in 64% of the 55 specimens processed in parallel.

Poisoning of wildlife in southern Africa.

Wildlife can be poisoned by both plants and chemicals. The co-evolution of wildlife and toxic plants has resulted in an increased resistance to these substances as compared with domestic animals. Both groups of animals are however susceptible to chemical poisons.

Paralysis and lipofuscin-like pigmentation of farm stock caused by the plant, Trachyandra laxa var. laxa.

A paralytic condition of farm stock in South West Africa, characterized by prominent neuronal and some mild extraneuronal pigmentation, is described. The distribution of the pigment, which was mainly located in the larger neurones of the brain and spinal cord, is given. Experimental evidence, obtained by feeding the plant, is presented that the condition is caused by Trachyandra laxa var.

Photosensitivity in South Africa. II. The experimental production of the ovine hepatogenous photosensitivity disease geeldikkop (Tribulosis ovis) by the simultaneous ingestion of Tribulus terrestris plants and cultures of Pithomyces chartarum containing the mycotoxin sporidesmin.

The mycoflora of toxic pastures were surveyed during a number of outbreaks of ovine hepatogenous photosensitivity in South Africa. Pure cultures of several isolates were dosed to sheep, but only those of Pithomyces chartarum and Myrothecium verrucaria proved to be toxic. Photosensitization was induced in sheep by dosing them with cultures of a P.

Observations on the pathology of canine microsporidiosis.

The available literature on canine microsporidiosis indicates that this disease, primarily of young dogs, is a distinct clinicopathological entity. It has been confused with canine distemper and rabies, and must be differentiated from toxoplasmosis. Information available on the spectrum of pathological change associated with this disease is incomplete but a distinct pattern emerges from a study of the reports.

Geeldikkop: preservation of toxic material.

Wilted Tribulus terrestris plants were harvested from a camp in which geeldikkop had just previously broken out. The plants were treated in various ways in an attempt to preserve their toxicity. The only successful method of preservation found was rapid freezing of harvested material.

Maldronksiekte in cattle: a neuronopathy caused by Solanum kwebense N.E. Br.

A neurological disease of cattle (maldronksiekte), occurring in a localized area of the Northern Transvaal, was experimentally reproduced by feeding Solanum kwebense plants to cattle. The disease is characterized by temporary loss of balance and transient epileptiform seizures precipitated by a variety of stimuli, such as exercise, handling (dipping, loading, etc) and fright. When not disturbed, most affected animals appear to be completely normal.

Cordophilosis and fatal gastro-intestinal verminosis in eland.

Fatal cases of cordophilosis and gastro-intestinal verminosis in eland are reported. Some of these cases were complicated with heartwater or cytauxzoonosis. Cordophilosis resulted in acute cardiac arrest.

Blindness and encephalopathy caused by Helichrysum argyrosphaerum DC. (Compositae) in sheep and cattle.

An outbreak of amaurosis and paresis was observed amongst sheep, and occasionally cattle, which had been grazing on pastures consisting mainly of Helichrysum argyrosphaerum DC. A similar syndrome was produced by feeding the suspect plant to sheep, thereby providing proof if its toxicity. Although none of the sheep became blind and only one developed paralysis, typical sponly lesions were detected in the brains and optic fasciculi of all the experimental animals.

Observations on naturally acquired hepatozoonosis of wild carnivores and dogs in the Republic of South Africa.

Hepatozoonosis was studied in hyaenas, lions, jackals, cheetahs and one leopard in the Kruger National Park and compared with the condition seen in dogs in the Republic of South Africa. Hepatozoon schizonts were found in the wild carnivores. The genesis of microschizonts was followed and is illustrated.
