Availability of healthy and unhealthy foods in modern retail outlets located in selected districts of Greater Accra Region, Ghana

Background

Intake of unhealthy foods is linked to the onset of obesity and diet-related non-communicable diseases (NCDs). Availability of unhealthy (nutritionally poor) foods can influence preference, purchasing and consumption of such foods. This study determined the healthiness of foods sold at modern retail outlets- supermarkets and mini-marts in the Greater Accra Region of Ghana.

Methods

All modern retail outlets located in six districts of Greater Accra were eligible. Those < 200 m² of floor area and with permanent structures were categorized as mini-marts; and those ≥200 m² as supermarkets. Shelf length of all available foods were measured. Healthiness of food was determined using two criteria - the NOVA classification and energy density of foods. Thus, ultra-processed foods or food items with >225 kcal/100 g were classified as unhealthy. The ratio of the area occupied by unhealthy to healthy foods was used to determine the healthiness of modern retail outlets.

Results

Of 67 retail outlets assessed, 86.6% were mini-marts. 85.0% of the total SHELF area was occupied by foods categorized as unhealthy (ranging from 9,262 m² in Ashiaman Municipality to 41,892 m² in Accra Metropolis). Refined grains/grain products were the most available, occupying 30.0% of the total food shelf space, followed by sugar-sweetened beverages (20.1% of total shelf space). The least available food group-unprocessed staples, was found in only one high income district, and occupied 0.1% of the total food shelf space. Retail outlets in two districts did not sell fresh fruits or fresh/unsalted canned vegetables. About two-thirds of food products available (n = 3,952) were ultra-processed. Overall, the ratio of ultra-processed-to-unprocessed foods ranged from 3 to 7 with an average (SD) of 5(2). Thus, for every healthy food, there were five ultra-processed ones in the studied retail outlets.

Conclusion

This study reveals widespread availability of ultra-processed foods in modern retail outlets within the selected districts. Toward a healthier food retail environment, public health and food regulators, in partnership with other stakeholders need to institute measures that improve availability of healthy foods within supermarkets and mini-marts.

The Africa Food Environment Research Network (FERN): from concept to practice

Background:

Africa is contending with unhealthy food environments that are, in part, driving increasing rates of overweight, obesity and diet-related non-communicable diseases, alongside persistent undernutrition. This current paradigm requires expanded efforts – both in the volume and nature of empirical research, as well as the tools and capacity of those who conduct it. High quality and context-relevant research supports the development and implementation of policies that create healthy food environments.

Aim and approach:

This paper sets out the concept of the Africa Food Environment Research Network (FERN) initiative recently established by the Measurement, Evaluation, Accountability, and Leadership Support for non-communicable diseases (NCDs) (MEALS4NCDs) prevention project. Central to the Africa FERN initiative are: 1) building research capacity for innovative food environment research in Africa; 2) improving South–South, South–North partnerships to stimulate robust food environment research and monitoring in Africa and 3) sustaining dialogue and focusing priorities around current and future needs for enhanced food environment research and monitoring in Africa.

Conclusion:

The FERN initiative presents an opportune platform for researchers in Africa and the global North to weave the threads of experience and expertise for research capacity building, collaboration and advocacy, to advance food environment research.

Community perceptions on the factors in the social food environment that influence dietary behaviour in cities of Kenya and Ghana: a Photovoice study

OBJECTIVE

To explore communities' perspectives on the factors in the social food environment that influence dietary behaviours in African cities.

DESIGN

A qualitative study using participatory photography (Photovoice). Participants took and discussed photographs representing factors in the social food environment that influence their dietary behaviours. Follow-up in-depth interviews allowed participants to tell the 'stories' of their photographs. Thematic analysis was conducted, using data-driven and theory-driven (based on the socio-ecological model) approaches.

SETTING

Three low-income areas of Nairobi (n 48) in Kenya and Accra (n 62) and Ho (n 32) in Ghana.

PARTICIPANTS

Adolescents and adults, male and female aged ≥13 years.

RESULTS

The 'people' who were most commonly reported as influencers of dietary behaviours within the social food environment included family members, friends, health workers and food vendors. They mainly influenced food purchase, preparation and consumption, through (1) considerations for family members' food preferences, (2) considerations for family members' health and nutrition needs, (3) social support by family and friends, (4) provision of nutritional advice and modelling food behaviour by parents and health professionals, (5) food vendors' services and social qualities.

CONCLUSIONS

The family presents an opportunity for promoting healthy dietary behaviours among family members. Peer groups could be harnessed to promote healthy dietary behaviours among adolescents and youth. Empowering food vendors to provide healthier and safer food options could enhance healthier food sourcing, purchasing and consumption in African low-income urban communities.

Advertising of unhealthy foods and beverages around primary and junior high schools in Ghana's most urbanized and populous region

Introduction

The advertising of energy-dense, nutrient-poor foods and beverages is a common feature in obesogenic food environments. Such advertising, within and around settings where children live, learn, and play, negatively affects their food acquisition and consumption. We examined the extent and nature of food and beverage advertising around primary and junior high schools in Ghana's most populous and urbanized region, Greater Accra.

Materials and methods

Outdoor advertisements for foods and beverages within a 250 m road network distance of 200 randomly sampled schools were geocoded. For each food and beverage advertisement, information was collected on the setting, type, size, and number of product types featured in the advertisement. Promotional techniques (promotional characters and premium offers) used in advertisements were documented. Advertised foods and beverages were classified using the INFORMAS and NOVA food classification systems.

Results

A total of 5,887 advertisements were identified around the schools surveyed, 42% of which were for foods and beverages. Advertisements were most prevalent at food outlets (78% of all food advertisements), but also along roads and on non-food structures. Overall, 70% of food advertisements featured non-core/unhealthy products, while 12 and 14% had core/healthy and miscellaneous (including soup cubes, seasonings, and tea) products. About 4% of food advertisements had only a product/brand name or logo displayed. One out of two of the foods and beverages advertised were ultra-processed foods, 30% processed, 3% processed culinary ingredients, and 17% unprocessed or minimally processed foods. Sugar-sweetened beverages were the most advertised food product type (32%). Promotional characters were found on 14% of all food advertisements (most-69% were cartoons or manufacturer's characters), while 8% of all food advertisements had premium offers (including price discounts and gift/collectables).

Conclusions

There is an abundance of unhealthy food advertisements around primary and junior high schools in the Greater Accra Region. Policy actions such as restricting the promotion of unhealthy foods in children's settings are needed to protect pupils from such advertising practices.

Perspective: Food Environment Research Priorities for Africa-Lessons from the Africa Food Environment Research Network

Over the last 2 decades, many African countries have undergone dietary and nutrition transitions fueled by globalization, rapid urbanization, and development. These changes have altered African food environments and, subsequently, dietary behaviors, including food acquisition and consumption. Dietary patterns associated with the nutrition transition have contributed to Africa's complex burden of malnutrition-obesity and other diet-related noncommunicable diseases (DR-NCDs)-along with persistent food insecurity and undernutrition. Available evidence links unhealthy or obesogenic food environments (including those that market and offer energy-dense, nutrient-poor foods and beverages) with suboptimal diets and associated adverse health outcomes. Elsewhere, governments have responded with policies to improve food environments. However, in Africa, the necessary research and policy action have received insufficient attention. Contextual evidence to motivate, enable, and create supportive food environments in Africa for better population health is urgently needed. In November 2020, the Measurement, Evaluation, Accountability, and Leadership Support for Noncommunicable Diseases Prevention Project (MEALS4NCDs) convened the first Africa Food Environment Research Network Meeting (FERN2020). This 3-d virtual meeting brought researchers from around the world to deliberate on future directions and research priorities related to improving food environments and nutrition across the African continent. The stakeholders shared experiences, best practices, challenges, and opportunities for improving the healthfulness of food environments and related policies in low- and middle-income countries. In this article, we summarize the proceedings and research priorities identified in the meeting to advance the food environment research agenda in Africa, and thus contribute to the promotion of healthier food environments to prevent DR-NCDs, and other forms of malnutrition.

Providing Measurement, Evaluation, Accountability, and Leadership Support (MEALS) for Non-communicable Diseases Prevention in Ghana: Project Implementation Protocol

Background: This study describes the rationale, adaptation, and final protocol of a project developed to address the increase in obesity and nutrition-related non-communicable diseases (NR-NCDs) in Ghana. Code-named the Measurement, Evaluation, Accountability, and Leadership Support for NCDs (MEALS4NCDs) project, it aims to measure and support public sector actions that create healthy food marketing, retail, and provisioning environments for Ghanaian children using adapted methods from the International Network for Food and Obesity/NCDs Research Monitoring and Action Support (INFORMAS).

Methods: The protocol for this observational study draws substantially from the INFORMAS' Food Promotion and Food Provision Modules. However, to appraise the readiness of local communities to implement interventions with strong potential to improve food environments of Ghanaian children, the MEALS4NCDs protocol has innovatively integrated a local community participatory approach based on the community readiness model (CRM) into the INFORMAS approaches. The setting is Ghana, and the participants include health and nutrition policy-makers, nutrition and food service providers, consumers, school authorities, and pupils of Ghanaian basic schools.

Results: The study establishes a standardized approach to providing implementation science evidence for the prevention of non-communicable diseases (NCDs) in Ghana. It demonstrates feasibility and the innovative application of the INFORMAS expanded food promotion and food provision modules, together with the integration of the CRM in a lower-middle income setting.

Conclusion: The research will facilitate the understanding of the processes through which the INFORMAS approach is contextualized to a lower-middle income African context. The protocol could be adapted for similar country settings to monitor relevant aspects of food environments of children.

Urban physical food environments drive dietary behaviours in Ghana and Kenya: A photovoice study

We identified factors in the physical food environment that influence dietary behaviours among low-income dwellers in three African cities (Nairobi, Accra, Ho). We used Photovoice with 142 males/females (≥13 years). In the neighbourhood environment, poor hygiene, environmental sanitation, food contamination and adulteration were key concerns. Economic access was perceived as a major barrier to accessing nutritionally safe and healthy foods. Home gardening supplemented household nutritional needs, particularly in Nairobi. Policies to enhance food safety in neighbourhood environments are required. Home gardening, food pricing policies and social protection schemes could reduce financial barriers to safe and healthy diets.

The African urban food environment framework for creating healthy nutrition policy and interventions in urban Africa

This study developed, validated, and evaluated a framework of factors influencing dietary behaviours in urban African food environments, to inform research prioritisation and intervention development in Africa. A multi-component methodology, drawing on concept mapping, was employed to construct a framework of factors influencing dietary behaviours in urban Africa. The framework adapted a widely used socio-ecological model (developed in a high-income country context) and was developed using a mixed-methods research approach that comprised: i. Evidence synthesis consisting of a systematic review of 39 papers covering 14 African countries; ii. Qualitative interview data collected for adolescents and adults (n = 144) using photovoice in urban Ghana and Kenya; and iii. Consultation with interdisciplinary African experts (n = 71) from 27 countries, who contributed to at least one step of the framework (creation, validation/evaluation, finalisation). The final framework included 103 factors influencing dietary behaviours. Experts identified the factors influencing dietary behaviours across all the four levels of the food environment i.e. the individual, social, physical and macro levels. Nearly half (n = 48) were individual-level factors and just under a quarter (n = 26) were at the macro environmental level. Fewer factors associated with social (n = 15) and physical (14) environments were identified. At the macro level, the factors ranked as most important were food prices, cultural beliefs and seasonality. Factors ranked as important at the social level were household composition, family food habits and dietary practices. The type of food available in the neighbourhood and convenience were seen as important at the physical level, while individual food habits, food preferences and socioeconomic status were ranked highly at the individual level. About half of the factors (n = 54) overlap with those reported in an existing socio-ecological food environment framework developed in a high-income country context. A further 49 factors were identified that were not reported in the selected high-income country framework, underlining the importance of contextualisation. Our conceptual framework offers a useful tool for research to understand dietary transitions in urban African adolescents and adults, as well as identification of factors to intervene when promoting healthy nutritious diets to prevent multiple forms of malnutrition.

Investigating foods and beverages sold and advertised in deprived urban neighbourhoods in Ghana and Kenya: a cross-sectional study

OBJECTIVES

The aim of this study was to characterise the local foods and beverages sold and advertised in three deprived urban African neighbourhoods.

DESIGN

Cross-sectional observational study. We undertook an audit of all food outlets (outlet type and food sold) and food advertisements. Descriptive statistics were used to summarise exposures. Latent class analysis was used to explore the interactions between food advertisements, food outlet types and food type availability.

SETTING

Three deprived neighbourhoods in African cities: Jamestown in Accra, Ho Dome in Ho (both Ghana) and Makadara in Nairobi (Kenya).

MAIN OUTCOME MEASURE

Types of foods and beverages sold and/or advertised.

RESULTS

Jamestown (80.5%) and Makadara (70.9%) were dominated by informal vendors. There was a wide diversity of foods, with high availability of healthy (eg, staples, vegetables) and unhealthy foods (eg, processed/fried foods, sugar-sweetened beverages). Almost half of all advertisements were for sugar-sweetened beverages (48.3%), with higher exposure to alcohol adverts compared with other items as well (28.5%). We identified five latent classes which demonstrated the clustering of healthier foods in informal outlets, and unhealthy foods in formal outlets.

CONCLUSION

Our study presents one of the most detailed geospatial exploration of the urban food environment in Africa. The high exposure of sugar-sweetened beverages and alcohol both available and advertised represent changing urban food environments. The concentration of unhealthy foods and beverages in formal outlets and advertisements of unhealthy products may offer important policy opportunities for regulation and action.

Implementation of healthy food environment policies to prevent nutrition-related non-communicable diseases in Ghana: National experts' assessment of government action

Nutrition-related non-communicable diseases (NR-NCDs) are a global health problem, increasingly recognised as driven by unhealthy food environments. Yet little is known about government action to implement food environment-relevant policies, particularly in low-and lower-middle income countries. This study assessed government action, implementation gaps, and priorities to improve the food environment in Ghana. Using the Healthy Food-Environment Policy Index (Food-EPI), a panel comprising government and independent experts (n = 19) rated government action to improve the healthiness of food environment in Ghana against international best practices and according to steps within a policy cycle. Forty-three good practice indicators of food environment policy and infrastructure support were used, with ratings informed by systematically collected evidence of action validated by government officials. Following the rating exercise, the expert panel proposed and prioritized actions for government implementation. Three-quarters of all good practice indicators were rated at 'low'/'very little' implementation. Restricting the marketing of breast milk substitutes was the only indicator rated "very high". Of ten policy actions prioritized for implementation, restricting unhealthy food marketing in children's settings and in the media were ranked the highest priority. Providing sufficient funds for nationally-relevant research on nutrition and NCDs was the highest priority infrastructure-support action. Other priority infrastructure-support actions related to leadership, monitoring and evaluation. This study identified gaps in Ghana's implementation of internationally-recommended policies to promote healthy food environments. National stakeholders recommended actions, which will require legislation and leadership. The findings provide a baseline for measuring government progress towards implementing effective policies to prevent NR-NCDs.

Barriers and facilitators on cervical cancer screening among HIV women in Cote d’Ivoire

Background

With 50,000 death every year, cervical cancer is the fourth most common cause of death by cancer in sub-Saharan countries. Due to high risk human papilloma virus (hr-HPV) persistence on the cervix, leading to pre-malignous lesions, the disease is more frequent among HIV-positive women. In low- and middle-income countries, cervical cancer screening strategy relies on visual inspection with acetic acid, an operator-associated technic. As an alternative, HPV-based detection and its better performances are considered as it could lead to a potential screening uptake and women empowerment through self-sampling. Côte d’Ivoire, with a high HIV prevalence, is considering this innovative strategy. Yet, few studies analyzed the potential socio-cultural factors associated with cervical cancer screening in this context. Our study aims to assess beliefs and perceptions toward cervical cancer among HIV positive women in Abidjan, Côte d’Ivoire.

Methods

We performed in-depth interviews with 21 HIV positive women randomly attending a health center or member of a women’s association, in November 2018. All interviews were recorded and transcribed. A theoretical framework with the Health Belief Model and the PEN-3 was used to categorize women’s perceptions, enablers, nurturers, perceived gravity and self-efficacy about cervical cancer, screening and self-sampling technique introduction.

Results

Positive findings were knowledge about cervical cancer, awareness about women’s vulnerability and HIV status role on it and relationship to caregivers. Fear appeared as a barrier to screening but also a facilitator among women with health awareness. Negative findings were reluctance for HIV-associated diseases, poor screening knowledge and lack of resources to get treated. Self-sampling introduction was disregarded due to lack of self-confidence.

Conclusions

This study provides useful information for counselling and opens the door to HPV-based screening implementation.

Key messages

Beliefs and perceptions about cervical cancer screening among HIV women need to be assess before implementing a new strategy. Cervical cancer screening uptake will need to address fear, self-confidence and stigma.

Interactive activity and discussion

A representative of each group will be invited to share the outcomes and main points with the audience.

Seasonal gaps in measles vaccination coverage in Madagascar

INTRODUCTION

Measles elimination depends on the successful deployment of measles containing vaccine. Vaccination programs often depend on a combination of routine and non-routine services, including supplementary immunization activities (SIAs) and vaccination weeks (VWs), that both aim to vaccinate all eligible children regardless of vaccination history or natural infection. Madagascar has used a combination of these activities to improve measles coverage. However, ongoing massive measles outbreak suggests that the country was in a "honeymoon" period and that coverage achieved needs to be re-evaluated. Although healthcare access is expected to vary seasonally in low resources settings, little evidence exists to quantify temporal fluctuations in routine vaccination, and interactions with other immunization activities.

METHODS

We used three data sources: national administrative data on measles vaccine delivery from 2013 to 2016, digitized vaccination cards from 49 health centers in 6 health districts, and a survey of health workers. Data were analyzed using linear regressions, analysis of variance, and t-tests.

FINDINGS

From 2013 to 2016, the footprint of SIAs and VWs is apparent, with more doses distributed during the relevant timeframes. Routine vaccination decreases in subsequent months, suggesting that additional activities may be interfering with routine services. The majority of missed vaccination opportunities occur during the rainy season. Health facility organization and shortage of vaccine contributed to vaccination gaps. Children born in June were the least likely to be vaccinated on time.

DISCUSSION

Evidence that routine vaccination coverage varies over the year and is diminished by other activities suggests that maintaining routine vaccination during SIAs and VWs is a key direction for strengthening immunization programs, ensuring population immunity and avoiding future outbreaks.

Establishing the Cardiothoracic Ratio Using Chest Radiographs in an Indigenous Ghanaian Population: A Simple Tool for Cardiomegaly Screening

BACKGROUND

Cardiothoracic ratio is a simple and cheap tool in the estimation of heart size. It is a useful index of cardiac size evaluation, and a value of 50% is generally considered to indicate the upper limit of normal.

STUDY OBJECTIVE

This study is to ascertain the normal mean value in cardiothoracic ratio of Ghanaians using chest radiography to serve as baseline for screening for cardiomegaly.

METHODOLOGY

Standard postero-anterior radiographs of the -clients/patients were used in the study. The cardiothoracic ratio (CTR) was obtained by dividing the transverse cardiac diameter [sum of the horizontal distances from the right and left lateral-most margins of the heart to the midline (spinous processes of the vertebral bodies)] by the maximum internal thoracic diameter. Systematic sampling with appropriate inclusion and exclusion criteria were used to obtain a sample size of 1989.

RESULTS

The mean transverse cardiac diameter and cardiothoracic ratio increased with age. The transverse thoracic diameter increased with age until the sixth decade when it reduced with age. The mean CTR increased gradually with age with females having greater values than males. The mean CTR of the study population were 0.459, 0.467 and 0.452 for the general population, females and males respectively.

CONCLUSION

This study has been able to establish 0.459 as the mean CTR values for Ghanaians. It has also shown the relationship between age and clients/patient's cardiothoracic ratio which compares favourably with findings of a similar study in Nigeria, a neighbouring country in the West African sub region with similar ethnic and social structure.

The Ghanaian woman's experience and perception of ultrasound use in antenatal care

OBJECTIVE

To evaluate how Ghanaian women perceive the use, and their assessment of the experience, of antenatal ultrasound scanning.

DESIGN

Cross-sectional study, using interviewer-administered questionnaire, from 25th February to 16th April, 2011.

SETTING

Obstetrics Units of Korle Bu Teaching Hospital, Accra, University of Ghana Hospital, Legon and Ga South District Hospital, Weija.

METHODS

A total of 337 clients were randomly selected after delivery and interviewed. Issues addressed included why women went for antenatal ultrasound, their knowledge of the uses of ultrasound in pregnancy, information provided by health care providers, clients' eagerness to know the sex of their fetuses, and their overall assessment of the ultrasound scanning experience.

RESULTS

The mean number of scans was 2.2(1.1). Most were performed on the request of a doctor or midwife; 154(45.7%) were not told the reasons for the request and 185(54.9%) did not have the results explained to them. For 239(70.9%) women the sonographer did not explain the procedure before the examination; 89(26.4%) were allowed to ask questions and 61(18.1%) were allowed to see their fetuses on the monitor. One hundred and sixty respondents (47.5%) asked for and were told the sex of their fetuses, with accuracy at delivery of 86.5%.

CONCLUSION

Most respondents perceived antenatal ultrasound as a useful tool. There is lack of information flow from health care providers to clients concerning the indications for the ultrasound, the processes involved and the results of the procedure. Improvements in these areas are needed to enhance the experience of antenatal ultrasound among Ghanaian women.

Legal termination of pregnancy among teenagers and older women in Soweto, 1999-2001

BACKGROUND

Legal termination of pregnancy (TOP) was introduced in South Africa in 1996. No data are available to relate the numbers of TOPs to the total number of pregnancies in specific health regions. The level of use of TOPs by women of different age groups is not known.

OBJECTIVE

To determine the proportion of pregnancies that end in TOP, with special reference to maternal age, and to measure trends in use from 1999 to 2001.

SETTING

Greater Soweto, Orange Farm and Lenasia, a densely populated urban health region served by Chris Hani Baragwanath Hospital and comprehensive primary care reproductive health services.

METHODS

Two cross-sectional studies performed in 1999 and 2001, counting all pregnancies managed in state-run health services, including legal terminations, spontaneous miscarriages, ectopic pregnancies and deliveries.

RESULTS

There were 5,412 pregnancies in the study period (9 weeks) in 1999, and 5,316 in the study period (8 weeks) in 2001. The TOP rates decreased from 16.1% to 13.6% (P = 0.20). The TOP rates for teenagers decreased from 22.3% to 16.3% (P = 0.006), but were higher than those for older women (15.2% in 1999 and 13.2% in 2001, P = 0.006 and 0.028 respectively). TOP rates for teenagers 13-16 years decreased from 28.0% to 23.0% (P = 0.44), and rates for older teenagers declined from 21.0% to 14.9% (P = 0.008). In 2001, 16.2% of women aged 35 and above underwent TOP, compared with 12.7% of women aged 20-34 years (P = 0.014).

CONCLUSION

Use of TOP services was highest in women at the extremes of reproductive age. There was a significant decline in TOP rates among older teenagers between 1999 and 2001. These data, from a comprehensive urban reproductive health service, provide a benchmark for comparison elsewhere and in the future.

[Nosocomial urinary tract infections: retrospective study in a pediatric hospital]

Urinary tract infections (UTI) are the most frequent nosocomial infection in the adult, yet very few data are available concerning these infections in children. In a retrospective 1-year study in a paediatric hospital, we analysed the incidence of nosocomial UTI and the characteristics of the affected children. The incidence was of 1.97/1,000 admissions which represented 6.8% of all UTI diagnosed by the microbiology laboratory. Most cases were in surgery and neurology wards. The frequency was inversely proportional to the age, with 50% of children being less than 2 years old. Pathogens most frequently isolated were E coli (39%), Pseudomonas sp (12.1%) and Enterococcus sp (12.1%). When compared with the organisms found in all the urine cultures during the same period, two organisms were more frequently found in nosocomial urinary tract infections: Pseudomonas sp and Candida sp. Most patients presented one or more risk factors, mainly:bladder catheterisation (41.4%), prior antibiotic therapy (62%), cerebral palsy (6.9%). No bacteriema was observed. The diagnosis of nosocomial UTI must be interpreted with caution and needs close collaboration between microbiologists and paediatricians. These infections increase the cost of hospitalisation, but only exceptionally do they present with complications. Some risk factors are inherent in hospital conditions, but others can be reduced by improving hand washing or by changing catheterisation practices.

A 2-year study of Helicobacter pylori in children

From September 1990 to October 1992, Helicobacter pylori was searched for in 426 children, 2 days to 16 years old, requiring upper fibroscopy for various symptoms. H. pylori was detected in 77 children (18.1%). Recurrent abdominal pain was present in 63.3% of the patients with H. pylori versus 48.6% of a control group of 74 age-matched children negative for H. pylori, weight loss was present in 6.5% of the patients versus 0% of the control subjects, and a family history of peptic ulcer was present in 14.2% of the patients versus 5.4% of the controls. Micronodular gastritis was observed in 31 children with H. pylori infection (40.2%). Among the 24 children (31.1%) with H. pylori infection and a normal mucosa at endoscopy, 18 (75%) complained of recurrent abdominal pain. H. pylori was also found in 21 of 38 children (55.2%) being examined because of short stature. These findings indicate that H. pylori should be looked for in children with recurrent abdominal pain with or without weight loss or a family history of peptic ulcer. Its relevance in short-stature syndrome requires further clarification.

Absence of intrathecal synthesis of some interferon-alpha subtypes in bacterial meningitis

Sixty-five cerebrospinal fluid (CSF) samples from 54 infants and children with bacterial meningitis were analyzed for the presence of interferon (IFN)-alpha with a biologic assay. Of the 65 samples, 3 were positive (2-4 IU/mL) and only 1 of 56 collected early was at 4 IU/mL. These results suggest that some subtypes of IFN-alpha already reported as present in viral infections of the central nervous system are not detected in bacterial meningitis by our IFN assay. This difference may be helpful in differentiating bacterial from viral infections and also in evaluating the quality of the virologic investigation; moreover, the rarity of IFN-gamma in CSF in bacterial meningitis needs further investigation to understand its role in the pathogenesis of the disease.

Susceptibility of Alcaligenes denitrificans subspecies xylosoxydans to beta-lactam antibiotics

The susceptibility of 56 clinical isolates and two reference strains of Alcaligenes denitrificans subsp. xylosoxydans to beta-lactam agents was tested and related to beta-lactamase activity of the strains. The MICs of 12 beta-lactams determined by an agar dilution method showed that all the strains were sensitive to imipenem and moxalactam. Forty-one cloxacillin-sensitive beta-lactamase producing strains were highly susceptible to azlocillin, piperacillin and ticarcillin, and less susceptible to several cephalosporins (cefamandole, cefoperazone, ceftazidime). The 17 remaining beta-lactamase-producing strains, which were sensitive to clavulanic acid and to a lesser extent cloxacillin, had variable resistance to the penicillins tested and synergy was obtained when these penicillins were combined with clavulanic acid or tazobactam. The choice of agents for treatment of infections with this organism must take into account the susceptibility phenotype of clinical isolates.
