“…There has been a wide variation in oral cancer incidence reported across regions and the risk factors themselves vary by area and lifestyle. 9 It is to be noted that the reported incidences depend on the quality of cancer registries, which in Africa is often deplorable. 11,16 These incidences are therefore often far below reality, which is the case for all cancers in Africa.…”

“…[22][23][24] In South Africa, for example, the prevalence of oral cancer among young people (<45 years of age) is higher than the global average and is not always associated with traditional risk factors. 9 In Benin, one third of the patients (37.3%) were under 50 years of age. All these data should make oral cavity and oropharyngeal cancers a shared concern.…”

“…3,7,8 In Sub-Saharan Africa, cancer registries are generally poorly maintained with incomplete, unreliable and obsolete data. 9,10,11 Oral and pharyngeal cancers accounted for 3.6% of all cancers recorded in 2012 in sub-Saharan Africa. 11 The highest rates of oral cavity cancers have been reported in the African islands of the Indian Ocean and countries of Southern and Eastern Africa, while those of West Africa are generally much lower.…”

Background: The objective of the study was to study the epidemiological profile of malignant tumours of the oral cavity in Benin from January 2009 to 31 December 2014.Methods: This was a descriptive cross-sectional study that examined cancers of the oral cavity collected in the registers of the 5 anatomy and pathology laboratories in Benin as well as the only hospital in the country that sends its requests for histological examinations abroad. Results: With a rate of 19.8%, oral cavity cancer was the most frequent cancer localization in the ENT, head and neck sphere in Benin. The most frequent sites of cancers in the oral cavity were the palate (32.2%) followed by the tongue (25.4%) and the inner face of the cheeks (16.9%). The average age of the patients was 53.18±20.60 years with extremes of 1 year and 90 years. The sex ratio was 0.90. Squamous cell carcinoma was the most common histological type with 67.80%.Conclusions: Cancer of the oral cavity must be a priority for health authorities in Benin. Research must be initiated to determine the factors that contribute to it.

“…However, population upsurges are often difficult to detect in the remote and often inaccessible outbreak areas, and once swarms have escaped from these source areas, they become highly mobile and are difficult to track down and control in the vast invasion area. The red locust occurs in the solitary phase in the subtropical grassland areas of South Africa in northern Zululand and in the Kruger National Park, with isolated specimens also recorded from cultivated areas in other parts of the country [42]. For example, the red locust is occasionally observed in maize and wheat crops on the Highveld, with isolated egg pods being found between the maize rows (Price, pers.…”

The current paper provides a detailed review of the historical outbreaks of each of the four plague locust species found in South Africa, namely the brown locust, the African migratory locust, the red locust, and the southern African desert locust. The history and dynamics of the plague infestations and the major local outbreaks are summarized. The typical patterns of the outbreaks of the different species are described, and the threat of these locusts to agriculture in South Africa is defined. The brown locust produces regular outbreaks in the semi-arid Karoo, with large-scale eruptions of plague proportions occurring about once per decade. Patterns of outbreaks often repeat themselves, but the sheer size of the plague outbreaks is almost impossible to stop, and the brown locust has the potential to threaten food security throughout southern Africa. The African migratory locust produces outbreaks in some of the main maize and wheat cropping areas where it is difficult to control. This locust has taken advantage of the man-made crop environment to produce an extra generation per year that was not previously possible in the original grasslands. The coastal area of KwaZulu Natal Province in South Africa was a prime reception and breeding area for plague invasions of the red locust in the past, and the country, therefore, relies on the successful control of outbreaks in east and central Africa to prevent the recurrence of the plague invasions. The southern African desert locust occurs in the Kalahari Desert area, and outbreaks requiring chemical control are rare.

Background: Cervical cancer is the most common malignancy affecting South African women aged 15–44 years, with a higher prevalence among women living with HIV (WLWH). Despite recommendations for a screening target of 70%, the reported rate of cervical cancer screening in South Africa is 19.3%.Objectives: To investigate the adherence of healthcare workers to cervical cancer screening guidelines in a tertiary-level HIV clinic.Method: A retrospective cross-sectional record audit of women attending the Charlotte Maxeke Johannesburg Academic Hospital HIV Clinic over a 1-month period.Results: Out of 403 WLWH who attended the clinic, 180 (44.7%) were screened for cervical cancer in the 3 years prior to the index consultation. Only 115 (51.6%) of those women with no record of prior screening were subsequently referred for screening. Women who had undergone screening in the previous 3 years were significantly older (47 years vs 44 years, P = 0.046) and had a longer time since diagnosis of their HIV (12 years vs 10 years, P = 0.001) compared to women who had not undergone screening. There was no significant difference in CD4 count or viral suppression between women who had and had not undergone screening.Conclusion: The rate of cervical cancer screening in our institution is below that recommended by the World Health Organization and the South African National Department of Health.
