Prevalence of underweight, wasting and stunting among young children with a significant cognitive delay in 47 low-income and middle-income countries.

BACKGROUND: Undernutrition in early childhood is associated with a range of negative outcomes across the lifespan. Little is known about the prevalence of exposure to undernutrition among young children with significant cognitive delay. METHOD: Secondary analysis of data collected on 161 188 three- and four-year-old children in 47 low-income and middle-income countries in Rounds 4-6 of UNICEF's Multiple Indicator Cluster Surveys. Of these, 12.3% (95% confidence interval 11.8-12.8%) showed evidence of significant cognitive delay. RESULTS: In both middle-income and low-income countries, significant cognitive delay was associated with an increased prevalence of exposure to three indicators of undernutrition (underweight, wasting and stunting). Overall, children with significant cognitive delay were more than twice as likely than their peers to be exposed to severe underweight, severe wasting and severe stunting. Among children with significant cognitive delay (and after controlling for country economic classification group), relative household wealth was the strongest and most consistent predictor of exposure to undernutrition. CONCLUSIONS: Given that undernutrition in early childhood is associated with a range of negative outcomes in later life, it is possible that undernutrition in early childhood may play an important role in accounting for health inequalities and inequities experienced by people with significant cognitive delay in low-income and middle-income countries.

Association between early childhood caries and malnutrition in a sub-urban population in Nigeria.

BACKGROUND: To determine the association between malnutrition and early childhood caries (ECC) in children resident in sub-urban, Nigeria. METHODS: This study was a subset of a larger cross-sectional study the data of which was generated through a household survey conducted in Ile-Ife, Nigeria. The study's explanatory variable was malnutrition (underweight, overweight, wasting and stunting) and the outcome variable was ECC. Poisson regression analysis was used to determine the association between ECC and malnutrition. Variables (sex, frequency of sugar consumption, maternal knowledge of oral hygiene, oral hygiene status) associated with ECC in the primary study were adjusted for to obtain the adjusted prevalence ratio (APR). RESULTS: Of the 370 children, 20 (5.41%) were underweight, 20 (5.41%) were overweight, 67 (18.11%) were wasting, 120 (32.43%) were stunted and 18 (4.86%) had ECC. Factors associated with ECC were being stunted, underweight, overweight and fair oral hygiene. The prevalence of ECC was lower in children who were stunted (APR: 0.14; 95% CI: 0.03-0.69; p = 0.02), almost seven times higher in children who were overweight (APR: 6.88; 95% CI: 1.83-25.85; p < 0.001), and predictively absent in children who were underweight (APR: 0; 95% CI: 0-0; p < 0.001) when compared with children who had normal weight. Non-significant risk indicators for ECC included consuming sugar between meals three times a day or more, having low socioeconomic status and being female. CONCLUSIONS: For this study population, the indicators of malnutrition - being stunted, underweight, overweight - and fair oral hygiene were risk indicators for ECC. The frequency of sugar consumption was not a significant risk indicator when malnutrition was included as an explanatory variable for ECC in the study population.

Effects of nutrition and hygiene education on oral health and growth among toddlers in rural Uganda: follow-up of a cluster-randomised controlled trial.

OBJECTIVE: To examine the effect of a nutrition and hygiene education intervention on oral health behaviour and whether early onset of caries was related to child growth in rural Uganda. METHODS: Follow-up study of a cluster-randomised controlled trial conducted between October 2013 and January 2015. Data were available from 399 mother/child pairs (203 in the intervention and 198 in the control group) of the original trial (78%) when the children were 36 months old. Oral health behaviour was evaluated using questionnaires. Photographs of the maxillary anterior teeth were examined for unmistakably carious lesions, and 115 water samples from the study area were analysed for fluoride concentration. RESULTS: The frequency of cleaning of the child's teeth at 36 months was about twice as high in the intervention as in the control group (84.3% vs. 46.6%; P = 0.0001). Cavitated carious lesions occurred more frequently in the control than the intervention group (27.8% vs. 18.2%; P = 0.04). Extraction of 'false teeth' (ebiino), a painful and crude traditional operation, was profoundly reduced in the intervention group (8.9% vs. 24.7%; P = 0.001). There was no evidence of association between the occurrence of caries and child growth. CONCLUSIONS: The education intervention improved oral hygiene practices and reduced the development and progression of caries and extraction of ebiino. Early childhood caries was not clearly associated with child growth.

[Atypical scurvy associated with anorexia nervosa]. / Scorbut atypique associé à une anorexie mentale.

INTRODUCTION: Scurvy, or "Barlow's disease", is a widely described disease involving cutaneous and mucosal lesions resulting from vitamin C deficiency. Herein, we report a case of scurvy in a 48-year-old woman that was unusual in its atypical cutaneous-mucosal presentation as well as its association with anorexia nervosa. PATIENTS AND METHODS: A 48-year-old woman treated for depression for several years was admitted to hospital for her impaired general state of health. Over the last year, she had presented palmoplantar rash and episodes of perimalleolar oedema. The clinical examination showed the patient to have wasting syndrome, with a BMI of 11.9kg/m2, lower-limb oedema, palmoplantar fissures, geographic tongue, telogen effluvium and purpuric petechiae on her right knee. However, no gingival bleeding was noted and there was no loss of tooth enamel. The remainder of the clinical examination was normal. Blood tests revealed extremely low vitamin C levels without any other associated deficiencies, as well as laboratory signs of cytolysis and anicteric cholestasis without inflammatory syndrome. The diagnosis of anorexia nervosa was made by psychiatrists, despite the unusual age of onset. Favorable clinical outcome was rapidly achieved via a one-month course of vitamin C supplements at a daily dose of 1g. DISCUSSION: The absence of classical buccal-dental symptoms and the presence of keratotic dermatosis with fissures and ulcers on the hands and feet are atypical in scurvy; however, this diagnosis was confirmed by the existence of purpura evoking capillary fragility, the patient's drastically low vitamin C level and the rapid subsidence of symptoms following treatment with oral vitamin C alone. Anorexia nervosa was doubtless the cause of deficiency. This situation is rare and a systematic review of the literature in Medline via PubMed showed that only three reports of scurvy associated with mental anorexia have been published since 1975.

Interdisciplinary management of FGF23-related phosphate wasting syndromes: a Consensus Statement on the evaluation, diagnosis and care of patients with X-linked hypophosphataemia.

X-linked hypophosphataemia (XLH) is the most frequent cause of hypophosphataemia-associated rickets of genetic origin and is associated with high levels of the phosphaturic hormone fibroblast growth factor 23 (FGF23). In addition to rickets and osteomalacia, patients with XLH have a heavy disease burden with enthesopathies, osteoarthritis, pseudofractures and dental complications, all of which contribute to reduced quality of life. This Consensus Statement presents the outcomes of a working group of the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases, and provides robust clinical evidence on management in XLH, with an emphasis on patients' experiences and needs. During growth, conventional treatment with phosphate supplements and active vitamin D metabolites (such as calcitriol) improves growth, ameliorates leg deformities and dental manifestations, and reduces pain. The continuation of conventional treatment in symptom-free adults is still debated. A novel therapeutic approach is the monoclonal anti-FGF23 antibody burosumab. Although promising, further studies are required to clarify its long-term efficacy, particularly in adults. Given the diversity of symptoms and complications, an interdisciplinary approach to management is of paramount importance. The focus of treatment should be not only on the physical manifestations and challenges associated with XLH and other FGF23-mediated hypophosphataemia syndromes, but also on the major psychological and social impact of the disease.

Effects of thalidomide on HIV-associated wasting syndrome: a randomized, double-blind, placebo-controlled clinical trial.

OBJECTIVE: To evaluate the efficacy of thalidomide in treating wasting syndrome in patients with advanced HIV disease, and to assess the effects of thalidomide on circulating CD4+ T cells, and on HIV viral burden in peripheral blood mononuclear cells (PBMC). DESIGN: Randomized, double-blind placebo-controlled clinical trial. SETTING: Public tertiary care hospital in Mexico City. PATIENTS: Twenty-eight adults with advanced HIV disease being treated with antiretroviral therapy, and who had received antiretrovirals for at least 6 months, who did not have an active opportunistic infection, and who had 10% weight loss in the previous 6 months. INTERVENTIONS: Patients received thalidomide (100 mg by mouth, four times daily) or a matching placebo for the duration of the study (12 weeks). MAIN OUTCOME MEASURES: The main clinical endpoint for efficacy of thalidomide was weight gain or no progression of wasting. Secondary endpoints were Karnofsky performance status, CD4+ cell counts, and HIV viral burden in PBMC. RESULTS: Both groups were comparable in their baseline status. Therapeutic failure occurred in 10 out of 14 patients from the placebo group and in three out of 14 from the thalidomide group (P = 0.021). Weight gain occurred in one patient on placebo and in eight given thalidomide. The Karnofsky index was significantly higher by the end of the study in the thalidomide group (P = 0.003). Mild and transient somnolence and erythematous macular skin lesions were significantly more common in the thalidomide group. CD4+ T cell counts and HIV viral burden in PBMC did not change in either group. CONCLUSIONS: Results suggest that thalidomide not only impeded but also reverted the wasting syndrome, preserving the Karnofsky index in patients with advanced HIV disease. Thalidomide, at the dosage used in this study, had no effect on peripheral CD4+ T cells nor on HIV viral burden in PBMC.

Participatory diagnosis of a heat-intolerance syndrome in cattle in Tanzania and association with foot-and-mouth disease.

A heat-intolerance (HI) syndrome in cattle in Tanzania was suspected to be associated with previous, clinical foot-and-mouth disease (FMD). A participatory appraisal (PA) method called "matrix scoring" was used to explore livestock-keeper perceptions of association between HI and cattle diseases. A PA method called 'proportional piling' was used to estimate herd incidence of FMD and other diseases, herd incidence of HI, and association between HI and other cattle diseases. Use of matrix scoring and proportional piling with pastoral Maasai informants demonstrated association between FMD and HI. With agropastoral Sukuma informants, the matrix-scoring method did not indicate an association between FMD and HI, whereas the proportional piling method indicated a weak association. Results were supported by calculation of positive predictive values for herder diagnosis of HI and FMD. Clinical examination of cattle by veterinarians was used to confirm HI cases and detection of antibody to non-structural proteins of FMD virus was used to confirm previous clinical FMD.

Risk factors for noma disease: a 6-year, prospective, matched case-control study in Niger.

BACKGROUND: Noma is a poorly studied disease that leads to severe facial tissue destruction in children in developing countries, but the cause remains unknown. We aimed to identify the epidemiological and microbiological risk factors associated with noma disease. METHODS: We did a prospective, matched, case-control study in Niger between Aug 1, 2001, and Oct 31, 2006, in children younger than 12 years to assess risk factors for acute noma. All acute noma cases were included and four controls for each case were matched by age and home village. Epidemiological and clinical data were obtained at study inclusion. We undertook matched-paired analyses with conditional logistic regression models. FINDINGS: We included 82 cases and 327 controls. Independent risk factors associated with noma were: severe stunting (odds ratio [OR] 4·87, 95% CI 2·35-10·09) or wasting (2·45, 1·25-4·83); a high number of previous pregnancies in the mother (1·16, 1·04-1·31); the presence of respiratory disease, diarrhoea, or fever in the past 3 months (2·70, 1·35-5·40); and the absence of chickens at home (1·90, 0·93-3·88). After inclusion of microbiological data, a reduced proportion of Fusobacterium (4·63, 1·61-13·35), Capnocytophaga (3·69, 1·48-9·17), Neisseria (3·24, 1·10-9·55), and Spirochaeta in the mouth (7·77, 2·12-28·42), and an increased proportion of Prevotella (2·53, 1·07-5·98), were associated with noma. We identified no specific single bacterial or viral pathogen in cases. INTERPRETATION: Noma is associated with indicators of severe poverty and altered oral microbiota. The predominance of specific bacterial commensals is indicative of a modification of the oral microbiota associated with reduced bacterial diversity. FUNDING: Gertrude Hirzel Foundation.

Linfoma no-Hodgkin en un paciente con sida / Non-Hodgkin lymphoma in a patient with AIDS

Se presenta el caso clínico de un paciente de 44 años de edad, con diagnóstico de virus de inmunodeficiencia humana/sida desde el año 2003, que fue ingresado en el Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba por presentar aumento progresivo del volumen de la región anterior y lateral izquierda del cuello que se extendía hasta la zona anterior de la axila de ese lado, con cianosis y edema en esclavina, disfagia, tos seca irritativa, ronquera, así como astenia marcada, anorexia y pérdida de peso. El cuadro clínico y los resultados de los estudios analíticos e histológicos confirmaron la presencia de un linfoma no Hodgkin de alto grado, unido a candidiasis bucal y esofágica, y síndrome de consunción por el virus de inmunodeficiencia humana.

The case report of a 44 years patient with diagnosis of human immunodeficiency virus /aids since 2003 that was admitted to "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital in Santiago de Cuba is presented due to a volume progressive increase of the preceding and left lateral region of the neck that extended to the preceding area in the armpit of that side, with cyanosis and shoulder girdle edema, dysphagia, dry irritating cough, hoarseness, as well as marked asthenia, anorexia and weight loss. The clinical pattern and the results of the analytic and histological studies confirmed the presence of a high-grade non Hodgkin lymphoma, along with oral and esophageal candidiosis, and consumption syndrome due to the human immunodeficiency virus.

Presenting symptoms and signs in children referred for palliative care in Malawi.

A study of 95 children referred for palliative care was carried out at Queen Elizabeth Central Hospital in southern Malawi, to determine the prevalence of different symptoms and signs. Seventy-seven percent of the children had HIV, 17% had cancer and 6% had a variety of other diagnoses. The commonest symptoms spontaneously presented by patients and carers were pain (27%) cough (22%) and diarrhoea (18%). Pain was significantly more common among children with cancer than those with HIV/AIDS. Cough, diarrhoea and mouth sores were significantly more common in those with HIV/AIDS. Many symptoms were not volunteered initially, but were revealed on direct questioning. This uncovered that 84% had a history of weight loss, 56% had fever and 51% had mouth sores. The commonest physical signs were wasting (76%), lymphadenopathy (40%) and oral candida (40%). Forty-seven percent of children with HIV had either lost their mother or had a mother who was sick. The wide range of physical symptoms and frequency of sickness or death in the children's mothers demonstrates the need for palliative care to be holistic, addressing the manifold physical, emotional and social problems associated with chronic and terminal illness.

Nutritional status and dental caries in a large sample of 4- and 5-year-old South African children.

BACKGROUND: Evidence from studies involving small samples of children in Africa, India and South America suggests a higher dental caries rate in malnourished children. A comparison was done to evaluate wasting and stunting and their association with dental caries in four samples of South African children. DESIGN: Cross-sectional study based on random sampling of birth records of two age bands. METHODS: A total of 2,728 4- and 5-year-old South African children from one rural community and three urban communities were examined for nutritional status and dental caries. RESULTS: In the total sample prevalences of wasting were mild (28%), moderate (4%) and severe (2%). For stunting the prevalences were mild (13%), moderate (3%) and severe (1%). For both conditions rural children showed higher proportions than the other groups. Statistical analysis showed statistically significant differences for wasting and stunting between the study groups. No significant association was found between the prevalence of caries and stunting or wasting, but an association was noted between wasting and decayed, missing and filled (dmf) surfaces (P = 0.003). CONCLUSIONS: In the series of children studied, nutritional status was not found to be clinically relevant to dental caries prevalence and experience.
