A review of 367 triplet pregnancies

CITATION: Deale, C. J. C. & Cronje, H. S. 1984. A review of 367 triplet pregnancies. South African Medical Journal, 66:92-94.The original publication is available at http://www.samj.org.zaQuestionnaires were sent to 452 hospitals in the RSA and SWA/Namibia requesting information on triplet pregnancies over a 10-year period. Information on 367 sets of triplets from 150 hospitals was adequate for analysis. The incidence of triplets was 0,04% of all deliveries. As many as 45% of triplets were diagnosed during the first or second stage of labour. These infants had a significantly lower birth weight than those diagnosed at an antenatal clinic (P <0,01). The mean birth weights of babies that died in utero or neonatally (within 7 days) were significantly lower than those in survivors (P <0,0001). Caesarean section was the delivery method for 14% of 1002 infants and perinatal mortality was improved for the second and third babies in comparison with second and third babies delivered vaginally (P <0,003 and P <0,002 respectively). It is concluded that the diagnosis of triplets should be made at the earliest possible stage of pregnancy, and that following adequate antenatal care all triplets should be delivered by caesarean section, except under ideal uncomplicated conditions where vaginal delivery may be feasible.Publisher’s versio

Management of anterior vaginal prolapse in South Africa : national survey

LetterThe original publication is available at http://www.samj.org.zaTo the Editor: A national survey was done on the management of anterior vaginal prolapse (AVP) by registered gynaecologists and urologists in South Africa. Of 822 questionnaires posted, 30.2% were returned completed (23.2% from gynaecologists and 7.0% from urologists). The information supplied was anonymous and is probably a true reflection of current practice. Of concern were the 36.3% of respondents who did not use a recognised staging system, a low rate of pre-operative urodynamic investigation by gynaecologists (8.4%) and a high rate of synthetic mesh use by urologists (75.9%), even for primary procedures. This first survey among South African prolapse surgeons provides valuable insight into clinical practice.Publishers’ versio

Identifying flies used for maggot debridement therapy

To the Editor: The use of maggots to clean necrotic wounds, known as maggot debridement therapy (MDT), has long been known to the scientific world. Its use has been recorded since the 1500s when soldiers’ wounds were often infested with maggots. Napoleon’s surgeon, Baron Dominic Larrey, reported that wounds that were infested with maggots appeared to heal faster than those without maggots.1 William Baer is considered to be the founder of modern MDT. While treating soldiers in World War I, he noted the good condition of wounds that had been infested with maggots, and was the first doctor on record to experiment with the use of maggots in treating infections.1 MDT even featured in the recent version of the film ‘Spartacus’. Various species of flies have been used for MDT,1 the most commonly used being Lucilia sericata, a greenbottle blowfly (Figs 1 and 2). This fly is closely related to another greenbottle, L. cuprina, but L. cuprina feeds on live as well as necrotic tissue, which is undesirable in MDT. L. cuprina is commonly named the ‘sheep blowfly’ because it is responsible for fly-strike in sheep, a form of massive, usually rectal myiasis that can kill sheep. A recent article2 suggested that L. cuprina was being used successfully for MDT at the Eugene Marais Hospital Wound Care Centre (EMHWCC). As this would be inconsistent with international experience in MDT and at odds with the usual biology of L. cuprina, it was decided to check the identity of these flies

Utilisation of maternity services by black women in rural and urban areas of the Orange Free State

An epidemiological survey was undertaken to evaluate the utilisation of maternal services for black women in the Orange Free State. Two hundred and forty clusters were selected from the rural (farms) and urban (local authorities) black population and eight households were interviewed in each cluster. Information was gathered from 237 rural women (from 959 households) and 168 urban women (from 926 households) who had delivered a baby or aborted during the preceding year. Antenatal care was received by 71 % of the rural women and 87% of the urban women. Rural women delivered at home in 60% of cases while 37% delivered in hospitals. Only 23% of urban women delivered at home while 67% of their deliveries were conducted in hospitals. Nurses supervised deliveries in both instances in more than 60% of cases, but in rural areas traditional midwives managed 26% of the confinements. The conclusions are that the maternity service was largely provided by nurses and was predominantly limited to hospitals and homes. It is recommended that the quality of service be upgraded and more emphasis placed on midwife obstetric units

Maternal deaths in Bloemfontein, South Africa -1986 - 1992

Objective. Determination of the maternal mortality ratio and the main causes of maternal death.Setting. Pelonomi Hospital, a tertiary care and referral hospital in Bloemfontein.Methods. Review of prospectively completed structured questionnaires on all maternal deaths from 1986 to 1992.Results. The maternal mortality ratio at our institution was 171 per 100000 live births. Haemorrhage (25%), infection (24%) and hypertensive disease (18%) were the most important causes of death. Seventy-one per cent were direct obstetric deaths and 23% indirect; in the remaining 6%, the cause was uncertain. Of all deaths, 35% were considered preventable.Conclusions. The maternal mortality ratio has decreased since our previous report for the period 1980 - 1985, and haemorrhage has replaced infection as the leading cause of death

Earth Through the Eyes of NAPA-1: Commissioning Results and the Next Steps in CubeSat Earth Observation

Disruptive CubeSat technology has brought scientific missions within reach that were previously only achievable through larger spacecraft. Satellite Earth Observation is now the new frontier for governments, private industry, and academia. With the recent launch of the Napa-1 satellite the Royal Thai Airforce (RTAF) has joined the ranks by having its first ever Earth Observation CubeSat in space. Its design, launch, early operations (LEOPS), and commissioning have been carried out by ISISpace, supporting the market’s need for imagery from space. Napa-1, meaning firmament in Thai, is a 6U CubeSat with the Gecko Imager from SCS Space as its primary payload, capable of taking RGB snapshot images with a 39-meter ground sampling distance (GSD) from 500 km altitude. In addition, the TriScape camera from Simera Sense flies onboard as an in-orbit technology demonstrator and is capable of delivering high-quality images with a GSD of 5 meter in the RGB bands. With well over 200 images taken by the primary payload this paper will look back on this exciting first period of Napa-1’s operational life and proudly present the very first images taken by the satellite and the lessons learnt throughout this turnkey mission. With that many images taken and that much data generated, the implemented onboard- and on ground data handling systems have been put to the test. ISISpace has made use of KUBOS’ Major Tom for command and control and having integrated a low-level processing tool, also for image data preview and delivery. Insight is provided into the systems and tools in place for image target planning, image acquisition, satellite command and control, and data delivery to the customer. How is it ensured targets are successfully captured? How is the usefulness of the image data efficiently validated? Subsequently, how is knowledge transfer to the customer accomplished to ensure successful routine operations? ISISpace will share the valuable lessons learnt from the mission planning, data handling, operations, and training points of view and show relevant in-orbit data on, for example, attitude behavior and temperature. In parallel, ISISpace has taken the next step in CubeSat Earth observation by using Napa-1 as a baseline while accommodating larger data streams and leveraging a higher level of automation. Together with the companies Simera Sense and Pinkmatter Solutions, multispectral images with automated on ground data processing (L0 up to L3) are to be delivered by the follow-up mission, Napa-2, to be launched in the summer of 2021. Details on this mission, including a further outlook at how CubeSat imagery and on ground processing will be shaped in the next few years will be provided

Sustainability reporting practices: a comparative study of South African and Botswana listed companies

Sustainability reporting is a type of reporting concerning how entities deal with environmental, social, economic and corporate governance issues. This form of corporate reporting has become a primary form of corporate reporting – just like financial reporting. The purpose of this study was to determine the extent to which the sustainability reporting practices of the Johannesburg Stock Exchange (JSE) companies are comparable to those of the Botswana Stock Exchange (BSE) companies. The findings suggest that differences in the level of sustainability reporting could be due to fewer sustainable activities in the BSE sample or to inadequate reporting of sustainable activities in in the BSE sample. These results support the Institutional theory but seem to disagree with other theories that explain sustainability reporting. A study of Institutional differences between Botswana and South Africa is recommended.Financial Accountin

Prevalence of pre-cancerous lesions and cervical cancer in South Africa - A multicentre study

Objectives. To describe the age-specific prevalence rates of cancer of the cervix in South African women presenting for screening.Design. A multicentre prevalence survey in 10 geographically defined areas following a common core protocol. Services were located in existing service sites, with the exception of KwaZulu-Natal which used a mobile service. Women aged 20 years and above were eligible for inclusion.Outcome measures. Age-specific cervical cytologically diagnosed abnormality rates according to the Bethesda classification.Results. During the study 20 603 women participated. Eighty per cent of the sample had never had a Pap smear before and just over 91 % had not had a Pap smear in the last 5 years. Inthis study population 468 women screened (2.42%) were found to have low-grade squamous intra-epithelial lesions (LSIL) and the average age of these women was 33.1 years; 366 (1.8%) had high-grade SIL (HSIL) and these women were statistically significantly older at 37.97 years of age; and 92 women (0.47%) were found to have cytologically diagnosed invasive cancer. These women were significantly older, with an average age of 51.3 years. A clear relationship was found between age and LSIL, with younger women having a high rate of LSIL which decreases with increasing age. A similar but inverse relationship between age and invasive cancer is described, with the rate being low in young women and increasing with increasing age. A clear relationship between HSIL and age is not described in these data. The adequacy rate (satisfactory and satisfactory but limited) of the slides was 95%, and just under 92% of the study sample received their results. Not all women were appropriately referred and it was not possible to assess if women referred for treatment received it.Conclusions. These data indicate that cancer of the cervix is a common disease and that, similar to other countries, it is a disease of older women. These data give some positive indicators for future screening - older women will present for screening and the majority of women received their results. However, improvements in health system functioning are needed. A uniform national cytology reporting system is required as well as clear guidelines for providers on what action to take based on cytology reports. Linkage between the site of screening and treatment centre is inadequate and requires urgent attention in order to decrease cervical cancer mortality
