Access to oral rehydration solution and zinc supplementation for treatment of childhood diarrhoeal diseases in Sudan.

OBJECTIVES: The decline in diarrhoeal disease-related mortality globally has been attributed to the use of oral rehydration solution (ORS) and zinc supplementation. However, data on ORS and zinc supplementation in Sudan are scarce. We aimed to investigate the access to ORS and zinc treatments and the associated factors, through the analysis of the latest available data from Sudan-Multiple Indicator Cluster Survey (MICS)-2014 obtained from the United Nations Children's Fund (UNICEF). RESULTS: A total of 14,081 children were included in this analysis. During the 2 weeks preceding the survey, 29.3% of these children had a diarrhoeal disease. Only 18.9% and 14.8% of these children had received ORS and zinc supplements, respectively. Whereas children from the higher wealth index groups were more likely to receive ORS treatment (fourth group: AOR = 1.301; 95% CI 1.006-1.682), children from rural areas were less likely to receive ORS treatment (AOR = 0.666; 95% CI 0.552-0.803) and zinc supplements (AOR = 0.603; 95% CI 0.500-0.728). The results indicate the existence of unequal access to treatment of childhood diarrhoeal diseases among children under 5 years in Sudan.

Strong community-based health systems and national governance predict improvement in coverage of oral rehydration solution (ORS): a multilevel longitudinal model.

Diarrheal disease remains a leading cause of child death globally, especially in low and middle-income countries. Use of oral rehydration solution (ORS) for treatment of diarrhea in children, a very cost-effective intervention, remains below 50% in many countries. Here we use a multi-level longitudinal model to reveal important predictors of ORS use at the national level. The findings suggest that increasing government effectiveness along with increased implementation and affordability of community-based health programs can lead to substantial increases in ORS use. Key informant interviews with national health leaders in countries that significantly improved ORS coverage support these quantitative findings.

Electrolytes: Oral Electrolyte Solutions.

Oral electrolyte solutions are used widely for rehydration in diarrheal illness and to maintain hydration during vigorous exercise. In diarrheal illness, an oral rehydration solution (ORS) typically is preferred over intravenous fluids except for patients with severe dehydration. The preferred ORS is one similar to the glucose-containing reduced osmolarity World Health Organization ORS. There also are polymer-based solutions that use rice or wheat as the source of carbohydrates but these are not widely recommended. Use of other liquids, such as sport drinks, juice, soft drinks, and chicken broth is not recommended, though these can be considered for patients with no or mild dehydration. For maintaining hydration during exercise, particularly vigorous high-intensity exercise, recommendations are to consume fluids (ie, 5 to 7 mL/kg) and a sodium-containing snack at least 4 hours before. During exercise, individuals require 200 to 800 mL/hour of liquid that should contain 20 to 30 mEq/L of sodium. Carbohydrate intake is recommended during high-intensity exercise. Intake of excessive sodium-free fluids should be avoided to prevent exercise-induced hyponatremia. Additional fluids (ie, 1.5 L/kg of weight lost) can be consumed after exercise to restore hydration. Vitamin and mineral supplements are not recommended routinely for athletes unless known deficiencies exist.

Changes in plasma phosphate during in-patient treatment of children with severe acute malnutrition: an observational study in Uganda.

BACKGROUND: Children treated for severe acute malnutrition (SAM) are at risk of refeeding hypophosphatemia. Therapeutic diets have only recently become fortified with phosphorus to meet United Nations (UN) specifications, but to our knowledge no studies have investigated the effect. OBJECTIVE: The aim was to assess concentrations and correlates of plasma phosphate (P-phosphate) at admission and during treatment and to identify correlates of changes in P-phosphate. DESIGN: This was a prospective observational study in 6- to 59-mo-old children admitted for treatment of SAM to Mulago Hospital, Uganda. P-phosphate was measured at admission, on the second day of treatment with a therapeutic formula containing 75 kcal/100 mL and 560 mg phosphorus/L (F-75, Nutriset), at the start of the transition to a therapeutic formula containing 100 kcal/100 mL and 579 mg phosphorus/L (F-100; Nutriset), at day 2 of transition, and at discharge. RESULTS: Among 120 children, mean ± SD P-phosphate at admission was 1.04 ± 0.31 mmol/L and increased by 0.43 (95% CI: 0.35, 0.52) mmol/L during the first 2 d and more slowly toward discharge. Most (79%) children experienced their lowest P-phosphate concentration at admission, and none developed severe hypophosphatemia. P-phosphate was lowest in children with edema and with elevated C-reactive protein, and a lower increase was seen with increasing caretaker-reported severity of illness. Partially or fully replacing F-75 with rice porridge (i.e., a local practice to reduce diarrhea) during the first 2 d of stabilization was associated with a 0.34-mmol/L (95% CI: 0.18, 0.50 mmol/L) lower increase in P-phosphate during the same first 2 d. CONCLUSIONS: F-75, which complies with UN specifications and provides 73 mg phosphorus · kg(-1) · d(-1) (130 mL · kg(-1) · d(-1)), seems to prevent refeeding hypophosphatemia in children with SAM. Replacing this formula with rice porridge during the first days of treatment to manage diarrhea may have an adverse effect on P-phosphate concentrations. This study was registered at http://www.isrctn.com as ISRCTN55092738.

Diapers in war zones: ethnomedical factors in acute childhood gastroenteritis in Peshawar, Pakistan.

This article considers ethnomedical knowledge and practices among parents related to contraction of acute gastroenteritis among children in Peshawar, Pakistan. Research methods included analysis of the Emergency Pediatric Services' admission register, a structured interview administered to 47 parents of patients seen in the Khyber Medical College Teaching Hospital, semi-structured interviews of 12 staff, and four home visits among families with children treated at the hospital. The use of native research assistants and participant observation contributed to the reliability of the findings, though the ethnographic, home-visit sample is small. Our research indicated that infection rates are exacerbated in homes through two culturally salient practices and one socioeconomic condition. Various misconceptions propagate the recurrence or perserverance of acute gastroenteritis including assumptions about teething leading to poor knowledge of disease etiology, rehydration solutions leading to increased severity of disease, and diaper usage leading to the spread of disease. In our Discussion, we suggest how hospital structures of authority and gender hierarchy may impact hospital interactions, the flow of information, and its respective importance to the patient's parents leading to possible propagation of disease. These ethnographic data offer a relatively brief but targeted course of action to improve the effectiveness of prevention and treatment efforts.

Magnesium supplementation and high volume hydration reduce the renal toxicity caused by cisplatin-based chemotherapy in patients with lung cancer: a toxicity study.

BACKGROUND: Renal toxicity is a clinical problem that affects 28-42% of patients undergoing treatment with cisplatin. Renal toxicity can be minimized by high volume hydration with mannitol diuresis. Recent reports have shown that cisplatin induces depletion of Mg and that Mg supplementation can reduce renal toxicity. We hypothesized that Mg infusion combined with low volume hydration may not be sufficient to overcome cisplatin-induced renal toxicity. METHODS: In total, 85 patients with lung cancer receiving their first cycle of cisplatin-based chemotherapy at the Osaka City University Hospital were classified into three groups: those administered high volume hydration without Mg infusion (high-volume Mg-), high volume hydration with Mg infusion (high-volume Mg+), and with low volume hydration with Mg infusion (low-volume Mg+). Serum creatinine (sCr) and creatinine clearance (CrCl) were examined before and after treatment with cisplatin. Multivariable analysis was carried out to identify the most important contributing factors. RESULTS: There were no significant differences in pre-treatment sCr levels or CrCl between groups. In the high-volume Mg- group, post-treatment sCr significantly increased compared with pre-treatment levels, while post-CrCl significantly decreased compared with pre-treatment CrCl (p < 0.001 and p < 0.001, respectively). In the high-volume Mg+ group, there was no significant difference between pre- and post-treatment levels of sCr, or between pre- and post-treatment CrCl (p = 0.118 and p = 0.254, respectively). In the low-volume Mg+ group, there was a trend towards increased sCr levels and decreased CrCl after treatment (p = 0.068 and p = 0.055, respectively). Multivariate analysis revealed that the absence of Mg infusion and low-volume hydration were both independent factors for decreased CrCl (p < 0.001 and p = 0.001, respectively). CONCLUSIONS: High-volume hydration and Mg infusion reduces the renal toxicity induced by cisplatin. A low-volume Mg+ regimen may be considered for patients with adequate renal function.

Global burden of childhood diarrhea and interventions.

PURPOSE OF REVIEW: Diarrhea is a leading cause of morbidity and mortality among children under 5 years in low-income and middle-income countries. Over the past 2 decades under-five mortality has decreased substantially, but reductions have been uneven and unsatisfactory in resource-poor regions. RECENT FINDINGS: There are known interventions which can prevent diarrhea or manage children who suffer from it. Interventions with proven effectiveness at the prevention level include water, sanitation, and hygiene interventions, breastfeeding, complementary feeding, vitamin A and zinc supplementation, and vaccines for diarrhea (rotavirus and cholera). Oral rehydration solution, zinc treatment, continued feeding, and antibiotic treatment for certain strains of diarrhea (cholera, Shigella, and cryptosporidiosis) are effective strategies for treatment of diarrhea. The recent Lancet series using the 'Lives Saved' tool suggested that if these identified interventions were scaled up to a global coverage to at least 80%, and immunizations to at least 90%; almost all deaths due to diarrhea could be averted. SUMMARY: The current childhood mortality burden highlights the need of a focused global diarrhea action plan. The findings suggest that with proper packaging of interventions and delivery platforms, the burden of childhood diarrhea can be reduced to a greater extent. All that is required is greater attention and steps toward right direction.

Fluid resuscitation in sepsis: a systematic review and network meta-analysis.

BACKGROUND: Fluid resuscitation is the cornerstone of sepsis treatment. However, whether balanced or unbalanced crystalloids or natural or synthetic colloids confer a survival advantage is unclear. PURPOSE: To examine the effect of different resuscitative fluids on mortality in patients with sepsis. DATA SOURCES: MEDLINE, EMBASE, ACP Journal Club, CINAHL, HealthSTAR, the Allied and Complementary Medicine Database, and the Cochrane Central Register of Controlled Trials through March 2014. STUDY SELECTION: Randomized trials that evaluated different resuscitative fluids in adult patients with sepsis or septic shock and death. No language restrictions were applied. DATA EXTRACTION: Two reviewers extracted data on study characteristics, methods, and outcomes. Risk of bias for individual studies and quality of evidence were assessed. DATA SYNTHESIS: 14 studies (18916 patients) were included with 15 direct comparisons. Network meta-analysis at the 4-node level showed higher mortality with starches than with crystalloids (high confidence) and lower mortality with albumin than with crystalloids (moderate confidence) or starches (moderate confidence). Network meta-analysis at the 6-node level showed lower mortality with albumin than with saline (moderate confidence) and low-molecular-weight starch (low confidence) and with balanced crystalloids than with saline (low confidence) and low- and high-molecular-weight starches (moderate confidence). LIMITATIONS: These trials were heterogeneous in case mix, fluids evaluated, duration of fluid exposure, and risk of bias. Imprecise estimates for several comparisons in this network meta-analysis contribute to low confidence in most estimates of effect. CONCLUSION: Among patients with sepsis, resuscitation with balanced crystalloids or albumin compared with other fluids seems to be associated with reduced mortality.

Integrated community case management: quality of care and adherence to medication in Beneshangul-Gumuz Region, Ethiopia.

BACKGROUND: The International Rescue Committee (IRC) supports implementation of integrated Community Case Management (iCCM) in all 20 woredas (districts) of Benishangul Gumuz Region (BSG) in Ethiopia. OBJECTIVES: To identify the gaps in the provision of quality iCCM services provided by Health Extension Workers (HEWs) and to assess caregivers' adherence to prescribed medicines for children under five years of age. METHODS: We conducted a cross-sectional descriptive study with both quantitative and qualitative study methods. We interviewed 233 HEWs and 384 caregivers, reviewed HEW records of 1,082 cases, and organized eight focus groups. RESULTS: Most cases (98%) seen by HEWs were children 2-59 months old, and 85% of the HEWs did not see any sick young infant. The HEWs' knowledge on assessments and classification and need for referral of cases was above 80%. However; some reported challenges, especially in carrying out assessment correctly and not checking for danger signs. Over 90% of caretakers reported compliance with HEWs' prescription. CONCLUSION: Partners have successfully deployed trained HEWs who can deliver iCCM according to protocol; however, additional support is needed to assure a supply of medicines and to mobilize demand for services, especially for young infants.

Perceptions regarding oral rehydration solutions for the management of diarrhea in Guatemalan children: implications for diarrheal management in the Americas.

OBJECTIVE: To describe knowledge and perceptions regarding the use of oral rehydration solution (ORS) for the management of diarrheal diseases among formal and informal health care providers and community caregivers in the Guatemalan department of Santa Rosa, and to recommend strategies to increase ORS use for management of diarrhea in children. METHODS: From July to September 2008, in-depth, semi-structured interviews were conducted with formal health care providers; open-ended interviews were conducted with informal health care providers; and focus group discussions and pile sorting were carried out with community caregivers. RESULT: The study participants attributed episodes of diarrhea in children to culturally recognized or folk ailments (empacho, cuajo, and varillas) that are primarily treated by traditional healers. There were knowledge deficits about 1) dehydration as a manifestation of diarrhea, and 2) management of dehydration, including the use of ORS and the need to continue feedings during diarrheal episodes. Caregivers perceived bottled/ready-made ORS products and the more expensive over-the-counter antidiarrheal medications as superior to ORS packets in the treatment of diarrhea. CONCLUSIONS: In Guatemala, folk etiologies of disease differ from those of the biomedical establishment and influence the decisions made by caregivers when treating ill children, including those related to the use of ORS. Public health campaigns addressing the treatment and management of diarrheal diseases in Santa Rosa should recognize the ailments known as empacho, cuajo, and varillas and target them for ORS use by community caregivers as well as health care providers in both the formal and informal health sectors.

OBJETIVO: Describir los conocimientos y las ideas que tienen las personas que prestan atención de salud en el sector convencional, el sector no convencional y los cuidadores de la comunidad con respecto al uso de las soluciones de rehidratación oral en el tratamiento de las enfermedades diarreicas, en el departamento guatemalteco de Santa Rosa y recomendar estrategias encaminadas a aumentar la utilización de estas soluciones en el tratamiento de la diarrea en los niños. MÉTODOS: De julio a septiembre del 2008 se llevaron a cabo entrevistas exhaustivas semiestructuradas a los profesionales de salud y entrevistas con preguntas abiertas a los proveedores no convencionales de atención sanitaria y se organizaron debates en grupos de opinión y ejercicios de ordenamiento de tarjetas con los cuidadores de la comunidad. RESULTADOS: Los participantes en el estudio atribuyeron la causa de los episodios de diarrea en los niños a dolencias culturalmente aceptadas o populares (empacho, cuajo y varillas), que tratan principalmente los curanderos. Se observaron deficiencias en los conocimientos acerca de 1) la deshidratación como una manifestación de la diarrea y 2) el tratamiento de la deshidratación, incluido el uso de las soluciones de rehidratación oral y la necesidad de continuar la alimentación durante los episodios diarreicos. Los cuidadores consideraron las soluciones de rehidratación embotelladas o preparadas y los medicamentos antidiarreicos de venta libre, que son más costosos, como mejores opciones para el tratamiento de la diarrea que las soluciones de rehidratación oral. CONCLUSIONES: En Guatemala, el concepto popular y el de las instituciones biomédicas sobre la causa de las enfermedades es diferente e influye sobre las decisiones que toman los cuidadores al tratar a los niños enfermos, por ejemplo, las relacionadas con el uso de soluciones de rehidratación oral. Las campañas de salud pública que abordan el tratamiento y el manejo de las enfermedades diarreicas en Santa Rosa deben incorporar las dolencias conocidas como empacho, cuajo y varillas y fomentar el uso de las soluciones de rehidratación oral en estos casos, por parte de los cuidadores de la comunidad, los profesionales de salud del sector convencional y los proveedores de atención del sector no convencional.

The effects of sports drink osmolality on fluid intake and immunoendocrine responses to cycling in hot conditions.

We investigated the effects of two carbohydrate-based sports drinks on fluid intake and immunoendocrine responses to cycling. Six well-trained male cyclists completed trials on three separate days that involved cycling at 60% VO(2peak) for 90 min in hot conditions (28.1 ± 1.5ºC and 52.6 ± 3.1% relative humidity). During each trial, the subjects consumed ad libitum (1) an isotonic sports drink (osmolality 317 mOsm/kg), (2) a hypotonic sports drink (osmolality 193 mOsm/kg) or (3) plain water. The cyclists consumed significantly (p<0.05) more of the isotonic drink (1.23 ± 0.35 L) and hypotonic drink (1.44 ± 0.55 L) compared with water (0.73 ± 0.26 L). Compared with water (-0.96 ± 0.26 kg), body mass decreased significantly less after consuming the hypotonic drink (-0.50 ± 0.38 kg) but not the isotonic drink (-0.51 ± 0.41 kg). Blood glucose concentration was significantly higher at the end of the isotonic and hypotonic drink trials compared with the water trial. Neutrophil count and the plasma concentrations of catecholamines, interleukin 6 (IL-6), myeloperoxidase, calprotectin and myoglobin increased significantly during all three trials. IL-6 and calprotectin were significantly lower following the hypotonic drink trial compared with the water trial. In conclusion, hypotonic sports drinks are appealing for athletes to drink during exercise, and may help to offset fluid losses and attenuate some inflammatory responses to exercise.

Pedialyte promotes periodontal ligament cell survival and motility.

INTRODUCTION: The search still continues to find the best storage media for avulsed teeth. Unfortunately, some of the recommended storage solutions are not commonly found in households or do not preserve the periodontal ligament (PDL) cells long-term. The purpose of the present study was to determine whether Pedialyte is a viable alternative storage solution for avulsed teeth by assessing its ability to preserve human PDL cell viability. METHODS: Human PDL cells were exposed to 6 different storage solutions (minimal essential medium [MEMα], Hank's balanced salt solution [HBSS], non-fat milk, coconut water, Pedialyte, or tap water) for 2, 6, 24, or 48 hours at 4°C or 25°C. Cell viability was quantified immediately or 1 week after exposure. The effects of these storage solutions on PDL cell motility and bacterial proliferation were also examined. The results were statistically analyzed by analysis of variance. RESULTS: Pedialyte at 4°C and 25°C showed significantly (P < .001) higher cell survival compared with water after all time intervals. No significant difference was noted between control (MEMα), HBSS, coconut water, and Pedialyte at 4°C after 2 hours. Cells stored in Pedialyte for 24 hours at 25°C and assayed 1 week later showed significantly higher cell survivability compared with milk. Pedialyte supported significantly less bacterial growth compared with non-fat milk and coconut water. No difference in cell motility was observed for cells stored for 24 hours in Pedialyte, MEMα, HBSS, milk, or coconut water. CONCLUSIONS: Pedialyte is a viable alternative as a storage solution for avulsed teeth.

Systematic review of strategies to increase use of oral rehydration solution at the household level.

BACKGROUND: Diarrhea is one of the major causes of death in children under five years of age, disproportionately affecting children in low- and middle-income countries. Treatment of diarrhea with oral rehydration solution addresses dehydration and reduces diarrhea related deaths. The World Health Organization Programme for the Control of Diarrhoeal Disease began in 1978 and while global ORS access rates have improved substantially over the past forty years, rates of ORS use have stagnated. Investigation is required to understand which interventions are effective in promoting the use of ORS, and where there are gaps in the literature. METHODS: We conducted a systematic search of peer-reviewed and grey literature and included interventions to promote the use of ORS for the treatment of acute diarrhea in children under 6 years. We used a standardized grading format based on the Child Health Epidemiology Research Group guidelines and performed meta-analysis for all categories with more than one data point. RESULTS: We identified 19 studies for abstraction. For co-promotion of zinc and ORS, mothers in the intervention group were 1.82 (95% CI 1.17, 2.85) times more likely to use ORS to treat their child's diarrhea episode than mothers in the comparison group. Meta-analysis of ORS social marketing and mass media strategies indicates that mothers exposed to messages were 2.05 (95% CI, 0.78, 5.42) times more likely to use ORS to treat their child's diarrhea episode than unexposed mothers. However, this is not statistically significant. Both meta-analysis had significant heterogeneity and were graded as moderate/low and low quality, respectively. CONCLUSIONS: We found few studies of interventions to promote the use of ORS; many categories of interventions had only one study. While there are some promising results, this analysis reinforces the need for further investigation into approaches to increasing ORS use.

An alkalinizing oral rehydration solution containing lecithin-coated citrus fiber is superior to a nonalkalinizing solution in treating 360 calves with naturally acquired diarrhea.

The aim of this field study was to compare the efficacy and cost of 2 commercially available oral rehydration therapy (ORT) solutions in treating dairy calves with naturally acquired diarrhea. A total of 1,349 newborn Holstein-Friesian calves were prospectively enrolled in the study. Calves were housed in individual hutches and fed a mixture of pasteurized hospital milk and an all-milk protein milk replacer twice per day. Calves were monitored twice each day from d 2 of life until 30 d of age for the presence or absence of diarrhea, and were assigned a fecal score and a hydration score at each examination. Calves that developed mild to severe diarrhea that did not need intravenous fluids and did not have clinical evidence of concurrent disease (n = 360) were assigned randomly to receive 1 of 2 commercial ORT solutions: a hypertonic alkalinizing ORT containing lecithin-coated citrus fibers (Diaque, group D, n = 180; Boehringer Ingelheim, Ingelheim, Germany), and an isotonic nonalkalinizing ORT (RE-SORB, group R, n = 180; Pfizer Animal Health, New York, NY) for 2 to 8d; the duration of treatment depended on whether diarrhea was still present. No significant differences were observed in mortality rates or treatment failure rates between the 2 treatment groups. Fecal consistency returned to normal more quickly in group D calves than in group R calves; consequently, group D calves were treated for 1d less than were group R calves. The increase in body weight after 4d of treatment was larger in group D than in group R. The average daily gain from birth to weaning in calves that did not develop concurrent disease (such as pneumonia) during the study period tended to be higher in group D calves (0.53±0.11 kg/d) than in group R calves (0.51±0.09 kg/d). The smaller number of treatments at a lower cost per treatment produced a cost advantage of $4.82 per treated calf in group D calves compared with group R calves. Our findings support the concept that milk should continue to be fed to diarrheic calves that are being administered an ORT solution in order to maintain growth.

Management guidelines for acute infective diarrhoea / gastroenteritis in infants.

BACKGROUND: Acute onset vomiting and diarrhoea is one of the most common illnesses of infancy, and is second only to respiratory illnesses as a cause of childhood deaths worldwide. Existing guidelines for management of diarrhoea are often ignored in public and private practice, possibly because of a perception that the guidelines are too simple, or because of expectations of the need to give 'real' drug therapy to stop diarrhoea. OBJECTIVES: This guideline provides a problem-based approach to the basics of present-day management of acute gastroenteritis, and discusses the evidence for the recommendations. Recommendations. Each episode of diarrhoea must be seen as an opportunity for caregiver education in the prevention of the illness, in the 'what' and 'how' of oral rehydration and re-feeding, and in the recognition of when to seek help. The vast majority of patients recover rapidly, but serious complications do occur, and must be recognised and managed correctly. Validation. The guidelines are endorsed by the Paediatric Management Group (PMG) in South Africa. CONCLUSION: The aim of management is to help the child to maintain or regain hydration, and to recover from diarrhoea, with careful attention to adequate oral rehydration and judicious re-feeding.

Childhood diarrhoea: failing conventional measures, what next?

BACKGROUND: Diarrhoea is one of the leading causes of infant mortality. This article analyzes its contribution towards the realization of millennium development goal number 4 (MDG-4). METHODS: A PubMed search using keywords acute infant diarrhea together with prevalence, management, or prevention 23 of the 634 generated articles were reviewed for inclusion. RESULTS: WHO first expressed concern about diarrhoeal mortality in 1979. Two decades later it reported diarrhoea as the second leading cause of infant mortality worldwide. The annual death toll of 1.5 million is greater than AIDS, malaria and measles combined. Short term repercussions (dehydration, electrolyte imbalance, malnutrition, shock, death) plus long-term diminished fitness index, cognitive function, and school performance have major impact on society. Ever since its 1971 success, Oral Rehydration Therapy has been the cornerstone treatment of diarrhoea. Decreased compliance has been recorded worldwide with Kenya ranking first. Intravenous therapy is useful in preventing complications while anti-diarrhoeals and anti-microbials, are indicated in severe cases. Zinc supplementation has also proven effective, and is recommended along with rehydration. Furthermore, immunization and good hygiene prevent faecal-oral transmissions. CONCLUSION: MDG-4 aims to reduce childhood mortality by 2/3 by 2015. Studies, however, show minimal progress, and the target is likely to be missed. Efforts must therefore be made to review existing strategies and formulate newer ones. Research priorities need to move away from perceived 'killer diseases' since far more children die in a day than have ever died from avian influenza for example.

Zinc sulphate for treatment and prevention of diarrhoea and other conditions in children in Papua New Guinea.

Over the last 10 years more than 40 randomized trials of zinc sulphate in diarrhoea have been done in developing countries throughout the world. Almost all have shown a benefit of zinc therapy for 5-10 days, if given with oral rehydration solution, in reducing the severity and duration of severe diarrhoea and preventing diarrhoea in the subsequent 3 months. Zinc has also been proven to reduce mortality in the management of children with severe malnutrition. Two studies have shown a benefit of zinc treatment on the clinical resolution of pneumonia and another study from Africa showed that zinc adjuvant treatment led to a significant reduction in mortality from pneumonia. Despite this overwhelming evidence, few countries in the Asia-Pacific region have scaled up the use of zinc in the treatment or prevention of diarrhoea or other infections. The reasons for this are several, including obstacles to incorporating new treatments into routine drug procurement and distribution mechanisms, and failure to appreciate the steps involved in the promotion of new routine treatments. A much higher priority must be given to ensuring that children with malnutrition, diarrhoea and other infections have access to zinc and oral rehydration solution--both of which are low-cost and life-saving treatments.

Effect of oral rehydration solution on fatigue during outdoor work in a hot environment: a randomized crossover study.

OBJECTIVES: The effects of an oral rehydration solution (ORS) on fatigue were studied in workers engaged in manual work during the summer. METHODS: One hundred and fifty-three workers engaged in loading cargo onto aircraft at Tokyo International Airport who consented to participate in the study were the subjects. The study was carried out on two summer days with fine weather during the daytime shift. The subjects were randomly divided into two groups: with one group restricted to ORS intake and the other group having free-choice of their favorite drink (FAD) in a randomized crossover study. The subjects were asked about the amount of beverage that they consumed and the type of FAD that they chose on the days of the survey. The effects of the ORS and the FAD were compared using a visual analogue scale (VAS) to determine the degree of fatigue experienced immediately after completing work. RESULTS: The average wet bulb globe temperature (WBGT) on the survey days was 30 degrees C. The beverage intake during work was 1,000 ml for most participants and the most commonly chosen types of FAD were tea and coffee. The fatigue VAS was significantly lower on the ORS intake days than on the FAD intake days (50.0 +/- 18.3 vs. 53.9 +/- 16.3). CONCLUSIONS: The results of this study suggest that the intake of ORS during outdoor work in a hot environment would be effective for preventing industrial accidents and heat stroke. It is important to select an appropriate drink to ensure adequate intake of water and electrolytes.

[Is there any place for hypertonic saline for fluid resuscitation in septic shock]. / Il y a-t-il une place pour le sérum salé hypertonique dans les états septiques graves?

Fluid loading is the first step, necessary to care for severe sepsis. Two main classes of solutions are currently available: crystalloids and colloids. The concept of small volume resuscitation with hypertonic saline has emerged these last years in the care of traumatic haemorrhagic shock. The main benefits are the restoration of intravascular volume, improvement of cardiac output and improvement of regional circulations. Many experiments highlight modulation of immune and inflammatory cascades. We report the mechanisms of action of hypertonic saline based on experimental human and animal studies, which advocate its use in septic shock.
