A Cluster Randomized Controlled Evaluation of the Health Impact of a Novel Antimicrobial Hand Towel on the Health of Children Under 2 Years Old in Rural Communities in Nyanza Province, Kenya.

To assess the health impact of reusable, antimicrobial hand towels, we conducted a cluster randomized, yearlong field trial. At baseline, we surveyed mothers, and gave four towels plus hygiene education to intervention households and education alone to controls. At biweekly home visits, we asked about infections in children < 2 years old and tested post-handwashing hand rinse samples of 20% of mothers for Escherichia coli. At study's conclusion, we tested 50% of towels for E. coli. Baseline characteristics between 188 intervention and 181 control households were similar. Intervention and control children had similar rates of diarrhea (1.47 versus 1.48, P = 0.99), respiratory infections (1.38 versus 1.48, P = 0.92), skin infections (1.76 versus 1.79, P = 0.81), and subjective fever (2.62 versus 3.40, P = 0.04) per 100 person-visits. Post-handwashing hand contamination was similar; 67% of towels exhibited E. coli contamination. Antimicrobial hand towels became contaminated over time, did not improve hand hygiene, or prevent diarrhea, respiratory infections, or skin infections.

Dermatological conditions in international pediatric travelers: epidemiology, prevention and management.

With an increasing number of children traveling internationally, there has been growing interest in studying the burden of travel-associated illnesses in children. We reviewed recently published (2007-2012) studies on travel-associated illness in children, and extracted the reported spectrum of dermatological conditions in children. Dermatologic problems are among the leading health concerns affecting children during and after return from international travel. Most are mild and self-limited, but an extended spectrum of conditions has been reported from a large retrospective multicenter study. Children may be especially at risk for infections related to environmental exposures, arthropod-related problems, and animal bites. Of note are also tropical and cosmopolitan systemic infections with potential for transmission in the receiving communities. Implications for pre- and post-travel care of children are emphasized.

Epidemiological assessment of mucocutaneous infections in patients with recurrent infection syndrome.

BACKGROUND: Recurrent infection syndrome (RIS) results from repeated interactions between hosts and environmental infectious agents and is considered normal (NRIS) because of its benign evolution and positive effects in the development of normal immune responses. Abnormal RIS (ARIS) is characterized by the unusually high frequency of severe infections, either as a result of anatomical or functional abnormalities or due to primary or secondary immunodeficiencies (PIDs and SIDs, respectively). Recurrent mucocutaneous infections (MCIs) can be manifestations of RIS or ARIS and could be more frequent in primary immunodeficiencies. Similarly, etiologic agents might vary from what is observed in the general population. METHODS: We carried out a descriptive study to determine the prevalence of aerobic bacterial and fungal mucocutaneous infections in 452 patients with recurrent infections, using clinical records to establish immunological status associated with the presence and characteristics of the infections. Microbiological analyses from mucocutaneous lesions were used to confirm the etiology. RESULTS: We found mucocutaneous infections in 50 patients for a total of 62 episodes (bacterial or fungal infections in 38 vs. 12 patients, respectively). Mucocutaneous infections were more frequent (21.8% vs. 9.1%; OR = 2.8) and recurrent (8.7% vs. 0.2%; P = 0.000) in primary immunodeficient patients. Furthermore, those with defects in phagocytic cells presented more mucocutaneous infections (56.2%) than patients with other primary immunodeficiencies (11.3%; OR = 10.1). CONCLUSIONS: Bacterial and fungal mucocutaneous infections are more frequent and severe in primary immunodeficient patients, particularly those with defective phagocytosis. Early and adequate assessment of the nature of mucocutaneous infections in ARIS should impact the ability of physicians to treat promptly, avoid complications and reduce the costs of medical assistance.

[Prevention of wasting and opportunistic infections in HIV-infected patients in West Africa: a realistic and necessary strategy before antiretroviral treatment]. / Prévention de la dénutrition et des infections opportunistes chez lespatients infectés par le VIH en Afrique de l'Ouest: une démarche réaliste, nécessaire, préalabe aux antirétroviraux.

The medical inequalities between countries of the North and South (infrastructure, drug availability, medical techniques) are particularly marked in terms of the challenge posed by HIV infection. We propose a strategy for monitoring adult patients in West Africa that is appropriate to the situation in the field and to economic constraints. The aim of this strategy is to increase the quality of life and the life expectancy of HIV-infected adults and to prevent the overcrowding of hospital departments with patients in the terminal phase of AIDS. We analyzed the biological and clinical spectrum of HIV infection before the onset of the diseases that define AIDS (excluding pulmonary tuberculosis). We found that it was particularly important to diagnose B-stage diseases early, especially atypical chronic cutaneous and mucous diseases. Careful analysis of data from a routine hemogram (total lymphocyte count 2500/ml; paradoxical eosinopenia), even in the absence of a CD4 lymphocyte count, should also enable clinicians from a wide variety of health structures to identify the HIV-infected patients most likely to benefit from more detailed clinical follow up, prophylaxis of opportunistic infections using cotrimoxazole, nutritional checkups and prevention of wasting. Cachexia is the most common AIDS-associated disease in West African patients. It involves an overall decrease in calorific intake, diarrhea, immune system activation, an increase in TNFalpha production and greater energy expenditure when resting. Recent nutritional studies have shown that it is vital to optimize the calorific intake of HIV-infected patients presenting with chronic diarrhea, before the onset of severe immune deficiency, to prevent wasting. So, spontaneous calorific intake should de routinely determined in HIV-infected patients and an optimal diet provided. Specific training in nutrition is required for doctors and nurses, as is consideration of the logistic organization required to provide nutritional support to HIV-infected adults. Despite the large number of individuals infected and the lack of sophisticated paraclinical facilities, we feel that it is possible to establish rational management "a minima" of HIV infection in West Africa, whilst waiting for antiretroviral drugs to become more widely available. This strategy could be of direct benefit to patients without swallowing up the financial resources of the health system in expensive biological follow up. Such basic management is also required before the new antiretroviral drugs become widely available. Research should be carried out in parallel in several reference centers in West Africa to determine the most effective associations of antiretroviral drugs and the optimal timing of treatment during the course of infection and to assess the potential side effects of these drugs in HIV patients exposed to recurrent antigenic stimulation by a wide diversity of pathogens.

[Patient-oriented hospital hygiene (author's transl)]. / Patientenorientierte Krankenhaushygiene.

Primary objective of patient-oriented hospital hygiene is the reduction in frequency of the five most important nosocomial infections: urinary tract infection, wound infection, respiratory tract infection, sepsis and infection of the skin and subcutaneous tissue. The less the effect of individual measures on the rate of hospital infections, the less important these measures are. Patient-oriented hospital hygiene commences not with expensive renovations, but with measures such as improvement of certain nursing techniques (venous catheters, bladder catheters, tracheal tubes, wound care). The most important measures are hand washing and disinfection. Hygiene committees, hygiene officers and infection control nurses are essential. A large part of the funds for investment in extra staff in a hospital hygiene programme can be obtained by economizing in other areas (e.g. routine floor disinfection).
