Abstract
Hand hygiene represents the single most effective way to prevent healthcare-associated infections. The World Health Organization, as part of its First Global Patient Safety Challenge, recommends implementation of multi-faceted strategies to increase compliance with hand hygiene. A questionnaire was sent by the European Centre for Disease Prevention and Control to 30 European countries, regarding the availability and organisation of their national hand hygiene campaigns. All countries responded. Thirteen countries had organised at least one national campaign during the period 2000-2009 and three countries were in the process of organising a national campaign. Although the remaining countries did not have a national campaign, several reported regional and local hand hygiene activities or educational resources on national websites.

Abstract
BACKGROUND We investigated an outbreak of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infections that occurred among healthcare workers (HCWs) but not among residents of a long-term care facility (LTCF). METHODS Cases of S. aureus infection were sought by reviewing the medical records of residents and HCWs. In order to identify risk factors for the development of an S. aureus infection, an unmatched case-control study was conducted. Cases were all HCWs with a clinically compatible S. aureus infection; controls were HCWs with no history of a clinically compatible S. aureus infection. Cases and controls were interviewed and anterior nasal swabs were collected. RESULTS Over a period of 14 months, a total of eight cases were identified among practice nurses, giving an attack rate of 10% for this category of profession. All isolates were identified as MRSA Panton-Valentine leukocidin (PVL)-producing SCCmec type IV. By multivariate analysis, working in a specific zone and being a practice nurse were found to be statistically significant risk factors for infection. CONCLUSIONS The current outbreak indicates that HCWs may serve as vehicles for the entry of PVL-positive MRSA strains from the community into LTCFs, and that deficient hygiene practices and unrecognized carriage may facilitate spread. Given the increasing prevalence of PVL-positive MRSA infections worldwide, guidelines for the eradication of PVL-positive MRSA carriage within closed communities should be established and efforts to obtain cultures from compatible infections should be made.

Abstract
Starting in May 2007, an ongoing outbreak of infections due to carbapenem resistant KPC-2-producing Klebsiella pneumoniae occurred in a tertiary care hospital in Crete (Greece). The outbreak involved 22 patients, none of whom had travelled in a country with known high prevalence of such isolates. KPC-producing K. pneumoniae strains were mainly isolated from patients admitted in the Intensive Care Unit, on mechanical ventilation, with prolonged hospitalization, prolonged administration of antibiotics, and prolonged administration of carbapenems. Clinical diagnoses were: pneumonia (62% of cases), surgical site infection (19%), bacteremia (9.5%), urinary tract infection (4.7%), and peritonitis (4.7%). Overall, 61 KPC-producing K. pneumoniae isolates were recovered, mainly from the respiratory tract (59.1%), catheter tip (22.7%), surgical site (18.2%), and blood (18.2%). Among 16 patients for whom therapeutic data were available, 14 (87.5%) were treated with a combination of colistin and/or tigecycline and/or garamycin. Clinical failure was noted in 22.2% of 18 patients available for assessment of clinical outcome, and microbiologic failure in 87.5% of 8 patients available for assessment of microbiologic outcome. In conclusion, an outbreak of KPC-producing K. pneumoniae infections has occurred in a tertiary care hospital in Greece, with significant associated morbidity and mortality. Prospective studies are required to evaluate the available therapeutic options for these infections. Our efforts should focus on rational use of available antibiotics, enhancement of infection control measures, and implementation of active antibiotic resistance surveillance.

Abstract
A 46-year-old woman with disseminated intravascular coagulation (DIC) died in a hospital in Alexandroupoli, in north-eastern Greece, in the end of June 2008. The woman was admitted to the hospital four days earlier, with fever, malaise, myalgia, chills and abdominal pain. One day before death, her condition deteriorated rapidly and she developed heavy hemorrhage from the genital tract, DIC and multi-organ failure. The patient reported a tick bite four days before admission, and that she had tried to remove the tick herself. No travel abroad was reported. She was engaged in agricultural activities in a rural area near the town of Komotini, in Rhodope prefecture, south of the Greek-Bulgarian border.

Abstract
Influenza vaccination rates are generally low among healthcare workers (HCWs) worldwide. In September 2005, the Hellenic Center for Disease Control and Prevention conducted a nationwide campaign to promote influenza vaccination in hospital HCWs. During the 2005-2006 influenza season, the overall vaccination rate among HCWs was 16.36% (range: 0-85.96%). The self-reported vaccination rate during the previous season was 1.72%, indicating a 9.5-fold increase. Compared with physicians, significantly fewer technical personnel were vaccinated, whereas administrative personnel were more likely to receive the vaccine. Among clinicians, rates for internal medicine departments exceeded those of surgical departments by a factor of 2.71 and laboratory medicine departments by a factor of 2.36. Multivariate analysis showed lower vaccination rates in large hospitals (>200 beds) than in smaller hospitals and lower rates in hospitals with specialist services (intensive care unit, psychiatry or dermatology) than in general hospitals. Factors associated with higher rates included working in northern Greece, in a paediatric or an oncology hospital, or in a prefecture with avian influenza H5N1 activity. In conclusion, in Greece influenza vaccination rates among HCWs remain low, but the implementation of a nationwide campaign had a considerable impact. Efforts should focus on hospital- and HCW-associated factors to increase vaccination uptake.

Abstract
Scabies is a parasitic dermatosis with a worldwide distribution. This infestation affects millions of people annually and may cause large nosocomial outbreaks with considerable morbidity among patients and healthcare workers. Immunocompromised or elderly institutionalized patients admitted with unrecognized crusted scabies are the main source of nosocomial transmission. Factors that facilitate the development of hospital-acquired scabies and nosocomial epidemics are: poor knowledge of scabies epidemiology, unfamiliarity of healthcare workers with atypical presentations, long incubation period, diagnostic delay and incomplete monitoring. Within hospitals, containment of an outbreak relies on the strict implementation of appropriate infection control measures and treatment administration to contacts. It is associated with a considerable working and economic burden.

Abstract
Influenza is the most important cause of acute respiratory illness leading to hospitalization among children during community epidemics. This illness can cause extensive nosocomial outbreaks with serious morbidity and mortality among specific groups of children. Paediatric patients with community-acquired influenza and healthcare workers are the main reservoir for the nosocomial spread of the virus. During epidemics in the community, testing for influenza should be requested in all children with compatible symptoms admitted in the hospital, and measures should be introduced for the prevention or early control of an outbreak. Recent advances in the management of influenza include rapid diagnoses based on antigen detection and the identification of the new neuraminidase inhibitors zanamivir and oseltamivir. Annual vaccination against influenza of children with high-risk conditions, their family members and healthcare workers is the principle measure for the prevention of nosocomial outbreaks. Although vaccination against influenza appears to be cost-effective at all ages in terms of prevention of illness, related hospitalizations, deaths, reduction of healthcare costs and productivity loss, vaccination coverage among target groups is limited.

Abstract
The aim of this study was to describe the etiology, morbidity and hospitalization costs associated with acute diarrhea among hospitalized children in Greece. During 1999, 294 hospitalized children (median age 1 y) with acute diarrhea were prospectively studied. Bacterial and viral enteropathogens were detected in 100 (34%) and 37 (12.5%) patients, respectively; 17 (6%) patients had mixed infections. Isolated agents included Salmonella spp. (43 patients; 15%), rotavirus (32; 11%), Campylobacter spp. (26; 9%), enteropathogenic Escherichia coli (16; 5.5%), Shigella spp. (11; 4%), Aeromonas spp. (7; 2.5%), adenovirus (6; 2%), Yersinia enterocolitica (6; 2%), enterohemorrhagic Escherichia coli (2; 0.5%) and Giardia lamblia (1; 0.5%). Of the patients with bacterial infection, 70% were admitted between April and September 1999. A rotavirus-associated peak was noted in March. Patients with a bacterial infection were hospitalized for longer periods than those with viral infections. It is concluded that bacterial enteropathogens account for one-third of admissions due to acute diarrhea among children in Greece and are associated with significant hospitalization costs. Rotavirus is also a frequent cause of acute diarrhea necessitating hospitalization.

Abstract
The role of epidemiological and clinical features for the early differential diagnosis between Mycobacterium tuberculosis (MTB) complex and non-tuberculous mycobacterial (NTM) cervical lymphadenitis in children was examined in this study. From 1982 to 1997, 24 MTB complex cases and 26 NTM cases were diagnosed, of which 75% and 25%, respectively, presented during the first half of the study period. Epidemiological and lymph-node features and anatomical areas were not helpful in the differential diagnosis between the 2 groups. Fulfilment of 2 out of 3 criteria (positive tuberculin skin test reaction, abnormal chest radiograph, contact with a person with infectious tuberculosis) was associated with 92% sensitivity for the diagnosis of MTB lymphadenitis. 37.5% of the MTB cases and 88.5% of the NTM cases were culture-confirmed; all inconclusive cultures concerned patients with spontaneous drainage and fistula. Surgical intervention was required in 67% of the MTB cases. All NTM cases were managed by surgery alone. Fistulae or cheloids occurred in all patients in whom incision and drainage were applied instead of total excision. Excellent aesthetic results were achieved in patients who presented within 1 month following the onset of lymphadenitis. The spectrum of mycobacterial cervical lymphadenitis in children in Greece has changed during the 1990s. Early and prompt treatment contributes to the diagnosis and response.

Abstract
The efficacy and safety of isepamicin at 7.5 mg/kg i.v. q 12 h was prospectively compared with that of amikacin at the same dose for the treatment of febrile neutropenic children with malignancies. Thirty-nine patients were enrolled in the study; 25 received isepamicin and 14 amikacin. Clinical and bacteriological response rates were 100% for both groups. No adverse events occurred. Median peak serum levels were 19.7 mg/l for isepamicin and 19.20 mg/l for amikacin. Median trough serum levels were 0.72 mg/l for isepamicin and 0.68 mg/l for amikacin. It was concluded that isepamicin was as effective and safe as amikacin for the treatment of febrile neutropenic children with malignancies, and might be used in areas where resistance to other aminoglycosides is a problem.

Abstract
The efficacy of piperacillin/tazobactam at 100/12.5 mg/kg every 8 h (35 patients) was compared to cefotaxime plus metronidazole at 50/7.5 mg/kg every 8 h (35 patients) in 70 children with intra-abdominal infections requiring surgery. Diagnoses were gangrenous or perforated appendicitis (n =56), peritonitis (n =12), and abscess (n =2). Clinical cure was observed in 35 of 35 evaluable patients treated with piperacilin/tazobactam and in 34 of 34 evaluable patients treated with cefotaxime plus metronidazole. Presumed bacteriological eradication was noted in 29 of 30 evaluable patients in the piperacillin/tazobactam group and in 31 of 31 evaluable patients in the cefotaxime plus metronidazole group. In this study, piperacillin/tazobactam was as effective as cefotaxime plus metronidazole for treating children with intra-abdominal infections requiring surgery.

Abstract
OBJECTIVE To describe the epidemiology and aetiology of acute diarrhoea among children treated exclusively in an outpatient setting in Greece. METHODS During 1999, children with acute diarrhoea who attended the emergency department of our hospital were prospectively studied. Patients requiring hospitalization were excluded. Stool specimens were tested microscopically, for bacterial enteropathogens by standard and selective medium cultures and for rotavirus and adenovirus by latex agglutination test. RESULTS One hundred and thirty-two children (median age: 2 years) were included in the study; an enteropathogen was detected in 63 (48%) of them. Isolates included rotavirus (19 patients), Salmonella sp (12), Campylobacter sp (10), Aeromonas sp (9), enteropathogenic Escherichia coli (6), adenovirus (6), Giardia lamblia (4), Yersinia enterocolitica (2) and Shigella sp (1). Half of the bacterial cases occurred from August to October, and two rotavirus-associated peaks occurred during February and August. Acute diarrhoea caused by viruses affected exclusively children under six years of age, mainly those attending day care centres. Macroscopic blood in stools was reported only among patients with a bacterial infection. Socioeconomic characteristics were not helpful in differentiating disease due to specific enteropathogens. CONCLUSIONS Bacterial enteropathogens account for a significant proportion of acute diarrhoea in children treated in the outpatient setting in Greece. Rotavirus is also a frequent cause affecting mostly younger children and those attending day care centers. The presence of blood in stools and the seasonality of bacterial infections may enable their presumptive diagnosis.

Abstract
BACKGROUND The etiology of Kawasaki syndrome (KS) is unknown. Rickettsiae, intracellular microorganisms that invade the vascular endothelium, might cause KS. OBJECTIVES To investigate whether there is an association between KS and infection with Rickettsia conorii, Rickettsia typhi, Coxiella burnetii or Ehrlichia phagocytophila group. METHODS All children who were diagnosed with KS at the University of Athens Second Department of Pediatrics from December, 1999, through November, 2000, were prospectively studied. Paired serum specimens were obtained from all patients and antibody titers against R. conorii, R. typhi, C. burnetii and E. phagocytophila group were assessed by microimmunofluorescence assay. RESULTS Eleven children with a median age of 2.5 years were included in the study. A 15-month-old child had a 4-fold rise of antibody titers against C. burnetii, which is indicative of acute Q fever. The patient had a history of recent exposure to possible sources of C. burnetii. The remaining patients tested negative for the presence of antibodies against R. conorii, R. typhi, C. burnetii and E. phagocytophila group. CONCLUSIONS Our study does not provide serologic evidence that KS is the result of infection with R. conorii, R. typhi, C. burnetii or E. phagocytophila group. It is suggested that C. burnetii may cause a KS-like illness in young children.

Abstract
Records were reviewed of 82 immunocompetent children (median age, 2. 5 years) from southern Greece who were diagnosed with visceral leishmaniasis from 1986 through 1998. Forty-nine (58%) patients originated from the city of Athens; of them, 46 (94%) lived by hills bordering the city. The median interval from the onset of symptoms to admission was 10 days. Fever and splenomegaly were observed in >95% of the patients. Thrombocytopenia was the most frequent hematological finding (80%). All patients were treated with meglumine antimonate; 20 (24%) of them were partially treated on an outpatient basis. Rapid clinical response was noted in all patients but one. Five patients relapsed; 3 responded to reintroduction of meglumine antimonate, 1 responded to liposomal amphotericin B, and 1 underwent splenic artery ligation. We conclude that pentavalent antimonials remain the first choice of treatment for visceral leishmaniasis in immunocompetent children in areas where resistance has not become a problem. It is possible to treat affected patients with outpatient administration of these agents, making them feasible options for therapy.

Abstract
METHODS The clinical and epidemiological features of 102 children with extra-pulmonary tuberculosis, diagnosed between 1982 and 1998 at P & A Kyriakou Children's Hospital were reviewed. RESULTS During the past decade, a 50% increase of admissions for extra-pulmonary tuberculosis was observed. The source of infection was disclosed in 48 patients. Diagnoses included superficial lymphadenitis (n = 48), pleural effusion (n = 27), meningitis (n = 16), skeletal tuberculosis (n = 5), miliary tuberculosis (n = 3), abdominal tuberculosis (n = 2), and pericarditis (n = 1). Miliary tuberculosis developed in infants, lymphadenitis and meningitis in preschool children, and pleural effusion and skeletal tuberculosis in older children. None of the patients with extra-pulmonary tuberculosis died; however, six patients with meningitis developed permanent neurological deficits. In these patients, antituberculous treatment was introduced at a median of six days following admission as compared with one day in patients with no complications. Poverty, immigration, and limited access to medical services were common among patients with meningitis.

Abstract
SETTING A worldwide re-emergence of tuberculosis has been observed during the last decade. However, few studies of infants with tuberculosis appear in the literature. OBJECTIVE To describe tuberculosis during infancy. DESIGN The records of all infants diagnosed with tuberculosis at a tertiary care hospital from 1982 to 1998 were reviewed. RESULTS Thirty-nine infants with a median age of 10 months were identified, 59% of whom presented during the second half of the study period. Diagnoses included endothoracic tuberculosis (33 patients), meningitis (3), miliary tuberculosis (2) and cervical lymphadenitis (1). Reasons for medical evaluation were the onset of symptoms (25 patients), contact investigation (12) and tuberculin skin test screening (2). Common signs and symptoms included fever (22 patients), cough (7), appetite loss (4) and wheezing/rales (4). Chest X-ray revealed hilar adenopathy (22 patients), infiltrates (16), atelectases (3) and miliary pattern (2). Cultures were attempted in nine patients and were positive in seven. All patients responded promptly to treatment. No complications or deaths occurred. CONCLUSION Tuberculosis in infants has been diagnosed increasingly during the last decade. Endothoracic tuberculosis predominates. One third of the patients were diagnosed due to contact investigation. As early diagnosis and treatment appears to prevent complications and reduce mortality, pediatricians should be alert for tuberculosis in an infant with an atypical picture suggestive of infection.

Abstract
BACKGROUND Although viral infection is a major clinical problem for hematopoietic stem cell transplant recipients, there are few large series reporting on these infections in the pediatric population. We performed a retrospective analysis of the impact of viral infections in this patient population in our center, managed by a uniform antiviral prophylaxis protocol. METHOD We reviewed the medical records of consecutive children and adolescents who received hematopoietic stem cell transplantation at the Division of Pediatrics, The University of Texas M. D. Anderson Cancer Center in Houston, TX, from July, 1992 to August, 1996. RESULTS During the study period there were 70 episodes of viral infections in 96 transplants. The viruses most commonly encountered were cytomegalovirus (24), varicella-zoster (21) and herpes simplex (10). Fifty of these episodes resulted in clinically apparent diseases, affecting 39 patients. The Kaplan-Meier estimated probability for the development of viral diseases was 62%. Ten percent of these patients died as a direct result of the infectious process, all within 4 months of transplant. Significant factors for development of viral disease were the development of acute graft-vs.-host disease and the duration of preengraftment neutropenia. CONCLUSIONS Viruses are common pathogens after hematopoietic stem cell transplantation in the pediatric population. Despite routine antiviral prophylaxis the morbidity and mortality of viral infections remain high. Enhancement of immune recovery after hematopoietic stem cell transplantation together with the development of new classes of antiviral agents may impact the incidence and prognosis of viral infections in this setting.

Abstract
In this study we compared the efficacy and safety of isepamicin versus amikacin at a dose of 7.5 mg/kg i.v. q12h for 10-14 days in children with pyelonephritis. Sixteen children were enrolled in the study; ten received isepamicin and six amikacin. Urine cultures grew Escherichia coli in all patients. All patients were treated successfully with either isepamicin or amikacin. Clinical and bacteriological response rates were 100% for both groups. No adverse events occurred. Peak serum levels ranged from 9.05 to 30.70 mg/l (median: 16.165) and from 12.20 to 25.90 mg/l (median: 19.05) for isepamicin and amikacin, respectively. Trough serum levels ranged from 0.11 to 3.20 mg/l (median: 0.75) and from 0.1 to 2.1 mg/l (median: 0.655), respectively. Isepamicin was shown to be as effective and safe as amikacin in the treatment of children with pyelonephritis and might prove an advantageous alternative in areas with high incidence of resistance to other aminoglycosides.

Abstract
OBJECTIVES To describe the clinical and epidemiologic features, management and outcome associated with the development of nontuberculous mycobacterial (NTM) superficial lymphadenitis in children. METHODS The medical records of all children 0 to 14 years of age with NTM superficial lymphadenitis who were diagnosed at P. and A. Kyriakou Children's Hospital between January, 1982, and December, 1997, were reviewed. RESULTS Forty-seven children were identified, 76.5% during the second half of the study period. Mycobacterium avium complex was the predominant isolate. Children with NTM lymphadenitis noted satisfactory aesthetic results when total excision was performed within 1 month after its onset. CONCLUSIONS NTM superficial lymphadenitis in children has been increasingly recognized during the last decade. Prompt total excision of the involved lymph node is required in such patients.

Abstract
Infectious complications are frequently encountered following Hickman-Broviac (H-B) catheter insertion. The medical records of 164 children with malignancies who underwent H-B catheter insertion from March 1, 1988 to December 31, 1997 were reviewed retrospectively. During a 35,697 catheter-day period, 77 catheter-related infections occurred, including 50 catheter-insertion-site infections and 27 bloodstream infections. The risk for the development of catheter-related infections was 2.15 per 1000 catheter-days (1.4 and 0.75 per 1000 catheter-days for catheter-insertion-site and bloodstream infections, respectively). In 17 (63%) of 27 episodes of bloodstream infections, antimicrobial treatment controlled the infection without catheter removal. A previous catheter-insertion-site infection caused by Staphylococcus epidermidis (p=0.01), the occurrence of mechanical catheter complications (p=0.007), and a normal coagulation status of the host (p=0.03) were significantly associated with the development of catheter-related bloodstream infections. H-B catheters remain important in pediatric oncology. Due to the significant morbidity associated with the development of catheter-related bloodstream infections, risk factors found to increase the incidence rate of such infections must be identified and properly managed.

Abstract
BACKGROUND The requirement for antimicrobial agents in patients with minor limb lacerations was prospectively studied. METHODS The development of wound infections in patients with minor limb lacerations who received amoxicillin plus clavulanate acid treatment (group A, 52 patients) was studied and compared with patients who did not (group B, 48 patients). RESULTS Wound infection occurred in 6 (11.5%) and 10 (21%) patients in groups A and B, respectively (p>0.10). Statistically significant risk factors for the development of infection were diabetes mellitus (odds ratio [OR], 15.8; p<0.001), lower limb lacerations (OR, 33.5; p<0.001), lacerations caused by compressive forces (OR, 21.6; p = 0.007), laceration length from 5 to 8 cm (OR, 7.04; p = 0.001), ragged laceration edge (OR, 2.55; p = 0.049), and skin tension (OR, 2.00; p = 0.006). CONCLUSION The use of antimicrobial agents in minor limb injuries was not associated with a significant reduction of infection rate. Routine antimicrobial treatment is discouraged.

Abstract
Children who undergo bone marrow transplantation (BMT) are at risk for Pneumocystis carinii pneumonia (PCP). Prophylaxis using trimethoprim/sulfamethoxazole (TMP/SMX) is highly effective but the incidence of adverse drug reactions is significant. We retrospectively reviewed 33 pediatric BMT (25 allogeneic and eight autologous) in whom dapsone was used for PCP prophylaxis because patients were unable to receive TMP/SMX. Dapsone was administered at 50 mg/m2 p.o. once a week from engraftment to 180 days post-autologous BMT, and to 1 year or throughout the duration of immunosuppressive treatment post-allogeneic BMT. With a total of 7268 patient days of dapsone prophylaxis and a median follow-up of 353 days post-BMT, no proven PCP was diagnosed. Sixteen cases of chest radiograph abnormalities were noted in this patient population but none was attributed to PCP. Dapsone was well tolerated by all children with no serious adverse effects; however, one patient developed Toxoplasma gondii encephalitis during dapsone prophylaxis. Dapsone warrants further evaluation as an alternative for PCP prophylaxis in pediatric BMT patients intolerant of TMP/SMX. Additional prophylaxis should be considered for patients at high risk for T. gondii encephalitis.
