OBJECTIVE: To determine whether the fever module in the WHO/UNICEF guidelines for the integrated management of childhood illness (IMCI) identifies children with bacterial infections in an area of low malaria prevalence. METHODS: Physicians assessed a systematic sample of 669 sick children aged 2-59 months who presented to the outpatient department of Dhaka Shishu Hospital, Bangladesh. FINDINGS: Had IMCI guidelines been used to evaluate the children, 78% of those with bacterial infections would have received antibiotics: the majority of children with meningitis (100%), pneumonia (95%), otitis media (95%) and urinary tract infection (83%); and 50% or less of children with bacteraemia (50%), dysentery (48%), and skin infections (30%). The current fever module identified only one additional case of meningitis. Children with bacteraemia were more likely to be febrile, feel hot, and have a history of fever than those with dysentery and skin infections. Fever combined with parental perception of fast breathing provided a more sensitive fever module for the detection of bacteraemia than the current IMCI module. CONCLUSIONS: In an area of low malaria prevalence, the IMCI guidelines provide antibiotics to the majority of children with bacterial infections, but improvements in the fever module are possible. 相似文献

Global changes, including an increase in trade and global warming, which act on the environment, are likely to impact on the evolution of pathogens and hence of diseases. To anticipate the risks created by this new situation, a French group of experts has developed a method for prioritising animal health risks. This is a two-phase method: the first step is to identify the diseases whose incidence or geographical distribution could be affected by the changes taking place, and the second step is to evaluate the risk of each of these diseases. As a result of this process, six priority diseases were selected: bluetongue, Rift Valley fever, West Nile fever, visceral leishmaniasis, leptospirosis and African horse sickness. The main recommendations were: to develop epidemiological surveillance, to increase knowledge of epidemiological cycles, to develop research into these diseases and to pool cross-border efforts to control them. 相似文献

Dengue haemorrhagic fever (DHF), the most severe form of illness following infection with a dengue virus, is characterized by plasma leakage and a period of increased microvascular permeability. Monitoring of plasma volume and body fluid compartment shifts is an integral part of the clinical management of DHF, and is crucial to the performance of clinical research studies on DHF pathogenesis. Multifrequency bioelectrical impedance spectroscopy (BIS) was assessed as a non-invasive method to monitor body fluid compartment shifts in children participating in a prospective, hospital-based, study of dengue virus infections in Thailand. Over the 48 h surrounding defervescence, the extracellular water/intracellular water ratio (ECW/ICW) rose in children with dengue virus infections and correlated with increasing disease severity [DHF > intermediate dengue fever (DF)/DHF > DF]. Plasma leakage remained within the ECW compartment and was not directly measured by multifrequency BIS. Expansion of the ECW space in DHF appeared to be primarily due to diminished renal water clearance. During the course of dengue illness, multifrequency BIS did not improve on serial haematocrit and bodyweight determinations for monitoring plasma volume contraction and ECW expansion, respectively. 相似文献

BackgroundThe use of 2 live attenuated vaccines (LAV) is recommended to be simultaneous or after an interval of at least four weeks between injections. The primary objective of this study was to compare the humoral response to yellow fever (YF) and measles vaccines among children vaccinated against these two diseases, either simultaneously or separated by an interval of 7–28 days.Subjects and methodsA prospective, multicenter observational study was conducted among children aged 9–15 months. The primary endpoint was the occurrence of positive yellow fever antibodies after YF vaccine by estimating the titers of neutralizing antibodies from venous blood samples. Children vaccinated against YF 7–28 days after receiving the vaccine against measles (test group) were compared with children vaccinated the same day against these two diseases (referent group).ResultsAnalysis was performed on 284 children. Of them, fifty-four belonged to the test group. Measles serology was positive in 91.7% of children. Neutralizing antibodies against YF were detected in 90.7% of the test group and 92.9 of the referent group (p =0.6). In addition, quantitative analysis of the immune response did not show a lower response to YF vaccination when it took place 1–28 days after measles vaccination.DiscussionIn 1965, Petralli showed a lower response to the smallpox vaccine when injected 4–20 days after measles vaccination. Since then, recommendations are to observe an interval of four weeks between LAV not injected on the same day. Other published studies failed to show a significant difference in the immune response to a LAV injected 1–28 days after another LAV. These results suggest that the usual recommendations for immunization with two LAV may not be correct.ConclusionIn low income countries, the current policy should be re-evaluated. This re-evaluation should also be applied to travelers to yellow fever endemic countries. 相似文献

In the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), which was conducted from 2003 to 2006, data on acute/infectious and chronic diseases were collected from a population-based sample of 17,641 subjects aged 0 to 17 years. The annual prevalence rates among acute diseases vary widely. Children and adolescents are most frequently affected by acute (infectious) respiratory conditions. 88.5 % of the surveyed children and adolescents experienced at least one episode of common cold within the last 12 months. Among the other acute respiratory infections, bronchitis and tonsillitis were the most frequently encountered conditions with 19.9 % and 18.5 %, respectively. The 12-month prevalence of otitis media and pseudocroup was 11 % and 6.6 %, respectively. 1.5 % of the children and adolescents experienced an episode of pneumonia. Apart from respiratory infections, gastrointestinal infections were very frequently stated as reasons for acute illness. Furthermore, 12.8 % of the children and adolescents experienced a herpetic infection, 7.8 % a conjunctivitis and 4.8 % a urinary tract infection. Lifetime prevalence rates of infectious diseases were as follows: pertussis 8.7 %, measles 7.4 %, mumps 4.0 %, rubella 8.5 %, varicella 70.6 %, scarlet fever 23.5 %. The various chronic somatic diseases in children and adolescents had different lifetime prevalence rates. Most frequently, children and adolescents were affected by obstructive bronchitis (13.3 %), neurodermatitis/atopic eczema (13.2 %) and hay fever (10.7 %). Scoliosis and asthma had been diagnosed by a doctor in 5.2 % and 4.7 % of subjects aged 0-17 years, respectively. The lifetime prevalence rates of the remaining diseases varied between 0.14 % for diabetes mellitus and 3.6 % for convulsions/epileptic fits. For the first time ever, these survey results provide nationwide representative information on the prevalence rates of acute/infectious and chronic diseases in children and adolescents which is based on a population-representative sample. 相似文献

OBJECTIVE: Decision making for health care at the household level is a crucial factor for malaria management and control among young children. This study sought to determine exactly how mothers reacted when faced with fever in a child. DESIGN: Qualitative study based on in depth semistructured interviews of mothers and free form discussion with traditional healers (Nganga). SETTING: Village of Dienga, a rural area of Gabon (Central Africa). PARTICIPANTS: 12 mothers and three traditional healers. RESULTS: All mothers thought that fever and malaria were identical. Mothers home treated or went to the village treatment centre, or both, on the last episode of fever, if they judged it to be "natural" fever. However, if fever was thought to be a result of malicious intent, then a Nganga was consulted first. It was believed that strong and above all persistent fever was "supernatural". In this case, traditional treatment was thought to be best. CONCLUSIONS: Results indicate that fever is perceived as a dual condition, with two distinct but non-mutually exclusive aetiologies (either "natural" or from witchcraft). In contrast with what is commonly believed, there seems to be no clear cut distinction between diseases suitable for management by western medicine and diseases to be managed solely by traditional health practitioners. Moreover, these data do not support the commonly held notion that the decision to seek western medicine to treat fever is considered a "last resort". Results strongly imply that some severe cases of fever, being initially considered supernatural, may partially or completely escape medical attention. 相似文献

Understanding community perceptions and attitudes towards childhood illness is important in developing appropriate interventions. A cross sectional survey was therefore, conducted in a riparian community of Lake Victoria basin in Tanzania to determine caretakers' perception, attitudes and practices on childhood malaria and diarrhoeal diseases. Among 336 caretakers interviewed, 61.1% (205) reported febrile illness in children within three months and 26.0% reported a diarrhoeal episode among children within two weeks before the survey. The majority of the respondents reported high fever (98.7%) and prostration (53.7%) as major symptoms of severe malaria. Convulsions were associated with high fever by only 13.7% of the respondents. Forty percent of the respondents attributed convulsions in children to either fever or malaria, and 24.4% correctly mentioned high fever or malaria. A health facility was the first point of care for childhood malaria for the majority (73%) of the respondents. In diarrhoeal diseases, prostration-weakness (67.7%) and dysentery (20.4%) were commonly reported among the respondents. Typical symptoms of severe dehydration (sunken eyes, loss of skin turgor, dry tears) were poorly recognised as characteristics of severe diarrhoeal diseases. Over 85% of the respondents practiced appropriate dietary measures or increased fluid intake for a child who had diarrhoea. Use of anti-diarrhoea (40.8%) and antibiotic medications (34.8%) were common in the treatment of diarrhoeal diseases. It is important that health education emphasizing recognitions of danger signs/symptoms of malaria and diarrhoeal diseases and their management is strengthened among riparian communities in Lake Victoria basin. 相似文献

A number of animal diseases can be transmitted to pigs via meat if the animals are fed scraps of meat imported from infected countries. For this reason, garbage feeding of pigs is regulated in many countries. The major porcine diseases recognised as being significant for this transmission pathway are foot and mouth disease, African swine fever, classical swine fever and swine vesicular disease. The World Organisation for Animal Health Terrestrial Animal Health Code (the Terrestrial Code) offers risk management recommendations for meat from countries where these diseases are present. However, there is no Terrestrial Code chapter on porcine reproductive and respiratory syndrome (PRRS), a relatively new viral disease of pigs which, since its recognition in the 1990s, has become endemic in most pig-producing countries. This paper assesses the risk of spread of PRRS virus through trade in pig meat, and concludes that the likelihood of its transmission by this pathway is negligible. 相似文献

Ten years after the publication of the recommendation: “Outbreak management and structural proceedings in case of cumulative occurrence of nosocomial infections” of the federal commission of hospital hygiene, these recommendations are now being re-evaluated. To date, the recommendations have proven valid and have maintained their significance for an effective management. However, besides new hygienic–microbiological methods and an increased sensitivity of the perception of nosocomial outbreaks by the public, by politicians and by the press, it is necessary to consider new issues in this field. Outbreaks are tragic events placing an extraordinary burden on all persons involved, which can have significant consequences. Therefore, it is necessary to ensure prompt outbreak management by experienced professionals who must combine a systematic on-site inspection, hygienic–microbiological investigation and typing methods used with epidemiological approaches. To assure these requirements, the support of independent reference centres such as universal hygiene institutes should be guaranteed. Politicians should be involved only after a scientific evaluation of the details of the outbreak has been made. A national documentation centre, e.g. at the Robert Koch Institute, should be established, thereby making experiences with outbreaks widely available. 相似文献

Preventing secondary infections among HIV-positive persons 总被引:1,自引:0,他引:1
Secondary infectious diseases contribute substantially to morbidity and mortality of people infected with human immunodeficiency virus (HIV). The authors developed comprehensive, practical recommendations for prevention of infectious complications in HIV-infected people. Recommendations are concerned with the pathogens that are more common or more severe in HIV-infected people. Several infectious complications can be prevented by avoiding ingestion of contaminated food or water. Zoonoses can be prevented by precautions to be taken in contacts with animals. The risk of several fungal diseases can be reduced if activities likely to lead to inhalation of spores are avoided. HIV-infected people should be advised how to lower adverse health effects of travel, especially international travel. The potential for infectious complications of sexual activity and illicit drug use should be stressed, and recommendations to reduce the risk are discussed. Recommendations for use of vaccines in HIV-infected people are reviewed. Blood CD4+ lymphocyte concentrations, tuberculin skin testing, Toxoplasma serology, and sexually transmitted disease screening should be performed in certain subsets of HIV-infected people. Guidelines for chemoprophylaxis against Pneumocystis carinii and tuberculosis are presented. Recent data suggest that intravenous immunoglobulin therapy may prevent bacterial infections in HIV-infected children. 相似文献

Group A streptococci (GAS) cause a wide spectrum of diseases ranging from benign pharyngitis and skin infections to severe invasive disease and the immune sequelae rheumatic fever and rheumatic heart disease. Pharyngitis, one of the most frequent diseases caused by GAS, is highly prevalent in school-age children in temperate climates and a major cause of antibiotic use. An efficacious vaccine would reduce disease burden associated with pharyngitis and the need of care for sick children. Importantly, GAS pharyngitis is recognised as the main precursor for acute rheumatic fever so a vaccine that is efficacious against GAS pharyngitis should also prevent acute rheumatic fever and rheumatic heart disease. It may also prevent post-streptococcal glomerulonephritis and invasive disease since GAS pharyngitis is one of the precursors for these clinical syndromes. There has been no clearly articulated pathway for clinical trial design leading to GAS vaccine registration. This review outlines a clinical development strategy detailing the phases of development required for registration of a candidate GAS vaccine for GAS pharyngitis initially, followed by impetigo and associated sequelae. The major advantages of a strategy first focused on GAS pharyngitis is an early proof of principle, that can be followed by studies for other clinical syndromes. The end goal being the availability of a preventive tool for the most prevalent GAS-associated diseases globally. 相似文献

Swimming pool attendance and exposure to chlorination by-products showed adverse health effects on children. We assessed whether early swimming pool attendance, especially baby swimming, is related to higher rates of early infections and to the development of allergic diseases. In 2003-2005, 2192 children were analysed for the 6-year follow-up of a prospective birth cohort study. Data on early swimming pool attendance, other lifestyle factors and medical history were collected by parental-administered questionnaire. Bivariate and multivariate logistic regression analyses were used to evaluate associations. Babies who did not participate in baby swimming had lower rates of infection in the 1st year of life (i) diarrhoea: OR 0.68 CI 95% 0.54-0.85; (ii) otitis media: OR 0.81 CI 95% 0.62-1.05; (iii) airway infections: OR 0.85 CI 95% 0.67-1.09. No clear association could be found between late or non-swimmers and atopic dermatitis or hay fever until the age of 6 years, while higher rates of asthma were found (OR 2.15 95% CI 1.16-3.99), however, potentially due to reverse causation. The study indicates that, in terms of infections, baby swimming might not be as harmless as commonly thought. Further evidence is needed to make conclusions if the current regulations on chlorine in Germany might not protect swimming pool attendees from an increased risk of gastrointestinal infections. In terms of developing atopic diseases there is no verifiable detrimental effect of early swimming. 相似文献

This article presents the World Health Organizations (WHO) evidence and recommendations for the use of yellow fever (YF) vaccination from “Vaccines and vaccination against yellow fever: WHO Position Paper – June 2013” published in the Weekly Epidemiological Record [1]. This position paper summarizes the WHO position on the use of YF vaccination, in particular that a single dose of YF vaccine is sufficient to confer sustained life-long protective immunity against YF disease. A booster dose is not necessary. The current document replaces the position paper on the use of yellow fever vaccines and vaccination published in 2003 [2].Footnotes to this paper provide a number of core references. In accordance with its mandate to provide guidance to Member States on health policy matters, WHO issues a series of regularly updated position papers on vaccines and combinations of vaccines against diseases that have an international public health impact. These papers are concerned primarily with the use of vaccines in large-scale immunization programmes; they summarize essential background information on diseases and vaccines, and conclude with WHO's current position on the use of vaccines in the global context. This paper reflects the recommendations of WHO's Strategic Advisory Group of Experts (SAGE) on immunization. These recommendations were discussed by SAGE at its April 2013 meeting. Evidence presented at the meeting can be accessed at http://www.who.int/immunization/sage/previous/en/index.html. 相似文献

Pediatric patients with severe chronic kidney disease (CKD) on conservative treatment, on dialysis, and those with renal transplantation are at a higher risk for infectious diseases as the result of impaired immune responses against infectious agents. Infections in these patients can have drastic consequences for disease morbidity and mortality. Immunization is a crucial preventive strategy for disease management in this pediatric population. However, vaccination coverage among children with CKD remains low due to safety concerns and doubts about vaccine immunogenicity and efficacy. In this study, we reviewed why children with CKD are at higher risk of infections, the importance of vaccinations among these children, barriers to vaccinations, and recommend the best vaccination schedules. Overall, vaccines have acceptable immunogenicity, efficacy, and safety profiles in children with CKD. However, in some cases, the protective antibody levels induced by vaccines and the benefits and risks of booster vaccine doses must be individually managed. Furthermore, close contacts and household members of these children should complete age-appropriate vaccination schedules to increase the child's indirect protection. 相似文献

Fluid and electrolyte management is challenging for clinicians, as electrolytes shift in a variety of settings and disease states and are dependent on osmotic changes and fluid balance. The development of a plan for managing fluid and electrolyte abnormalities should start with correcting the underlying condition. In most cases, this is followed by an assessment of fluid balance with the goal of achieving euvolemia. After fluid status is understood and/or corrected, electrolyte imbalances are simplified. Many equations are available to aid clinicians in providing safe recommendations or at least to give a starting point for correcting the abnormalities. However, these equations do not take into consideration the vast differences between clinical scenarios, thus making electrolyte management more challenging. The supplementation plan, whether delivered intravenously or orally, must include an assessment of renal and gastrointestinal function, as most guidelines are established under the assumption of normal digestion, absorption and excretion. After the plan is developed, frequent monitoring is vital to regain homeostasis. A fluid and electrolyte management plan developed by a multidisciplinary team is advantageous in promoting continuity of care and producing safe outcomes. 相似文献

Surveillance was conducted for three clinical syndromes (hemorrhagic fever, encephalitis, and hepatitis) in Cambodian children admitted to the National Pediatric Hospital in Phnom Penh from July 1996 through September 1998. Acute- and convalescent-phase sera, and cerebrospinal fluid, when applicable, underwent diagnostic evaluation for infections with Dengue virus (DENV), Japanese encephalitis virus (JEV), and Hepatitis A, B, C, and E viruses. Of 621 children admitted with hemorrhagic fever, 499 (80%) were confirmed to have either primary or secondary DENV infection. DENV rates were as high as 10.6/100 hospital admissions in September 1998. Of 50 children with clinical encephalitis, 9 (18%) had serologic evidence of JEV infection. Forty-four children had clinical hepatitis, most (55%) due to Hepatitis A virus (HAV). One patient had Hepatitis B virus, and no patients had hepatitis C or E. This study identified a large number of children with vaccine-preventable diseases (JEV and HAV). 相似文献

A 2.5-year-old boy and a 2-month-old girl presented with fever without an apparent source. Additional laboratory tests were requested due to alarming signs for the presence of a serious bacterial infection. Pneumonia and viral meningitis respectively were diagnosed, and adequate therapy led to a quick and complete recovery. Due to changing prospects following the near eradication of invasive Haemophilus influenzae type b (Hib) infections by vaccination, there are no suitable guidelines at present concerning fever without an apparent source in children. A selection of patients at risk can first of all be made based on patient history and a physical examination and secondly by carrying out additional laboratory tests. Furthermore, careful evaluation, clinical acumen, well-informed parents and observation are all important elements in the treatment of these patients. 相似文献

This article presents the World Health Organization’s (WHO) recommendations on the use of fractional doses of yellow fever vaccines excerpted from the “Yellow fever vaccine: WHO position on the use of fractional doses – June 2017, Addendum to Vaccines and vaccination against yellow fever WHO: Position Paper – June 2013″, published in the Weekly Epidemiological Record [1], [2].This addendum to the 2013 position paper pertains specifically to use of fractional dose YF (fYF) vaccination (fractional dose yellow fever vaccination refers to administration of a reduced volume of vaccine dose, which has been reconstituted as usual per manufacturer recommendations) in the context of YF vaccine supply shortages beyond the capacity of the global stockpile. The current WHO position on the use of yellow fever (YF) vaccine is set out in the 2013 WHO position paper on vaccines and vaccination against YF and those recommendations are unchanged.Footnotes to this paper provide a number of core references including references to grading tables that assess the quality of the scientific evidence, and to the evidence-to-recommendation table. In accordance with its mandate to provide guidance to Member States on health policy matters, WHO issues a series of regularly updated position papers on vaccines and combinations of vaccines against diseases that have an international public health impact. These papers are concerned primarily with the use of vaccines in large-scale immunization programmes; they summarize essential background information on diseases and vaccines, and conclude with WHO's current position on the use of vaccines in the global context.

Infections caused by streptococci pathogenic for man are some of the most common bacterial diseases in temperate zones and occur very frequently in tropical and subtropical countries. The highest morbidity occurs from infections caused by group A streptococci; these infections can lead to rheumatic fever and acute glomerulonephritis. The incidence of rheumatic fever and the prevalence of rheumatic heart disease are several times higher in tropical countries than temperate countries. 相似文献
