Health-care organization for the management and surveillance of SARS-CoV-2 infection in children during pandemic in Campania region, Italy

Background

In comparison with adults, severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection in children has a milder course. The management of children with suspected or confirmed coronavirus disease (COVID-19) needs to be appropriately targeted.

Methods

We designed a hub-and-spoke system to provide healthcare indications based on the use of telemedicine and stringent admission criteria, coordinate local stakeholders and disseminate information.

Result

Between March 24th and September 24th 2020, the Hub Centre managed a total of 208 children (52% males, median age, 5.2, IQR 2–9.6 years) with suspected or confirmed COVID-19. Among them, 174 were managed in cooperation with family pediatricians and 34 with hospital-based physicians. One hundred-four (50%) received a final diagnosis of SARS-CoV-2 infection. Application of stringent criteria for hospital admission based on clinical conditions, risk factors and respect of biocontainment measures, allowed to manage the majority of cases (74, 71.1%) through telemedicine. Thirty children (28%) were hospitalized (median length 10 days, IQR 5–19 days), mainly due to the presence of persistent fever, mild respiratory distress or co-infection occurring in infant or children with underlying conditions. However, the reasons for admission slightly changed over time.

Conclusion

An hub-and-spoke system is effective in coordinate territorial health-care structures involved in management paediatric COVID-19 cases through telemedicine and the definition of stringent hospital admission criteria.

The management of children with COVID-19 should be based on clinical conditions, assessed on a case-by-case critical evaluation, as well as on isolation measures, but may vary according to local epidemiological changes.

Increasing Tuberculosis Rates and Association With Migration in Children Living in Campania Region, Southern Italy: A 10-Year Cohort Study

BACKGROUND

Italy is classified as a low tuberculosis (TB) incidence country (rate 6.5/100,000 inhabitants). However, the Campania Region Pediatric Reference Centre (CRRC) observed an increase in TB, contemporarily with a rise in migration.Our aim was to investigate trends in TB notification rates, association with migration, and changes in clinical outcomes of children living in Campania.

METHODS

We conducted a prospective cohort study (January 1, 2009-December 31, 2018), including children <18 years who received diagnosis of TB at the CRRC. Yearly crude TB incidence rates and relative confidence interval (95% CI) were calculated. Two main outcome measures were considered: loss to follow-up and poor clinical outcome, including prolonged or second-line treatment, sequelae, or death.

RESULTS

Overall 146 children (52.1% male; median age, 50 months; interquartile range, 96.33) received a diagnosis of TB. TB incidence rates increased from 0.44 cases (95% CI: 0.16-0.97) per 100,000 inhabitants <18 years of age in 2009 to 1.84 cases (95% CI: 1.15-2.79) in 2018 (P < 0.05) and linearly correlated with the rate of migrants (R = 0.9272; P < 0.0001). Ziehl-Neelsen-positive children had an increased likelihood of poor clinical outcomes (odds ratio, 4.83; 95% CI: 1.28-18.2; P = 0.020). Compared with Italians, foreign children showed a lower likelihood of cure without sequelae (49.3% versus 67.9%; P < 0.001; odds ratio, 0.45; 95% CI: 0.23-0.89; P = 0.02). They accounted for all fatal cases and loss to follow-up.

CONCLUSION

Pediatric TB rate in Campania increased in the last 10 years in association with the increase in migration. Emphasizing national TB rates may disregard important differences in local infection trends and limit medical awareness about TB. Foreign children may need tailored management programs.

Measles Outbreak in a High-Income Country: Are Pediatricians Ready?

BACKGROUND

Measles is a highly communicable infection with potentially severe complications. It is rarely reported in high-income countries and the limited awareness and experience of pediatricians may result in misdiagnosis. The present study aimed at investigating physician's ability and timing to reach diagnosis during a recent outbreak in Italy.

METHODS

The Italian Society for Pediatric Infectious Diseases conducted a retrospective, multicenter study in children hospitalized for measles between 1 January 2016 and 30 August 2017 in secondary and tertiary care hospitals. The appropriateness of diagnosis at admission, the time to reach clinical diagnosis, and serological confirmation of measles were recorded.

RESULTS

At hospital admission, measles was misdiagnosed in 101 (40.5%) of the 249 children (median age, 14.5 months) enrolled. The appropriate diagnosis increased from 30% to 72.5% during the period of observation (P < .001). A greater chance of receiving an appropriate diagnosis was demonstrated in children who reported a contact with measles (odds ratio [OR], 5.2; 95% confidence interval [CI], 3.0-9.2) or in those seen in institutions that managed more cases (OR, 7.39; 95% CI, 3.22-16.9; P = .0001). In contrast, children with underlying chronic conditions had a higher risk of misdiagnosis (appropriate diagnosis OR, 0.19; 95% CI, 0.10-0.33). The mean time from the onset of symptoms to clinical diagnosis was 4.55 ± 2.2 days and to serological confirmation was 7.0 ± 3.4 days.

CONCLUSIONS

Measles is frequently misdiagnosed in low-prevalence settings. Specific measures to increase pediatricians' awareness about vaccine-preventable infections need to be implemented.

Thumb basal joint interpositional arthroplasty: a systematic review

The aim of this systematic review was to analyze the failure rates among different trapeziometacarpal interposition implants used to treat thumb basal joint osteoarthritis. We searched Medline (PubMed), Web of Science and Scopus databases, to identify articles reporting on thumb interpositional arthroplasty, in English literature. We excluded studies with less than 35 cases and with a follow-up shorter than 24 months. Twenty-one studies were included. We assessed the quality of the studies using the Coleman Methodological Score. The mean quality of the studies was moderate. The total number of procedures included in this review was 1205. The failure rate for interposition implants was 11%. The main longterm complication was dislocation, which is also the major reason for revision.

Complications and risk factors for severe outcome in children with measles

OBJECTIVE AND DESIGN

Risk factors for severe measles are poorly investigated in high-income countries. The Italian Society for Paediatric Infectious Diseases conducted a retrospective study in children hospitalised for measles from January 2016 to August 2017 to investigate the risk factors for severe outcome defined by the presence of long-lasting sequelae, need of intensive care or death.

RESULTS

Nineteen hospitals enrolled 249 children (median age 14.5 months): 207 (83%) children developed a complication and 3 (1%) died. Neutropaenia was more commonly reported in children with B3-genotype compared with other genotypes (29.5% vs 7.7%, p=0.01). Pancreatitis (adjusted OR [aOR] 9.19, p=0.01) and encephalitis (aOR 7.02, p=0.04) were related to severe outcome in multivariable analysis, as well as C reactive protein (CRP) (aOR 1.1, p=0.028), the increase of which predicted severe outcome (area under the receiver operating characteristic curve 0.67, 95% CI 0.52 to 0.82). CRP values >2 mg/dL were related to higher risk of complications (OR 2.0, 95% CI 1.15 to 3.7, p=0.01) or severe outcome (OR 4.13, 95% CI 1.43 to 11.8, p<0.01).

CONCLUSION

The risk of severe outcome in measles is independent of age and underlying conditions, but is related to the development of organ complications and may be predicted by CRP value.

Rates and determinants of antibiotics and probiotics prescription to children in Asia-Pacific countries

Antibiotic therapy may have important side effects. Guidelines recommend the administration of specific probiotics to reduce the risk of antibiotic-associated diarrhoea (AAD). The rates and determinants of antibiotics and co-prescription of probiotics in children remain poorly known in Asia-Pacific countries, which are very heterogenous in terms of economic development, health care organization and health policies. A survey among general practitioners (GPs) and paediatricians was performed in seven countries of the Asia-Pacific area (Australia, Japan, Indonesia, India, China, Singapore, and South Korea). Physicians completed an online questionnaire that explored their current habits and the determinants for prescribing antibiotics and probiotics. For the 731 physicians who completed the questionnaire (390 paediatricians and 341 GPs), 37% of all consultations for a child led to the prescription of antibiotics (ranging from 17% in Australia to 47% in India). A large majority of physicians (84%) agreed that antibiotics disrupted gut microbiota and considered probiotics an effective intervention to prevent AAD (68%). However, only 33% co-prescribed probiotics with antibiotics (ranging from 13% in Japan to 60% in South Korea). The main reasons for prescribing probiotics were previous episodes of AAD (61%), presence of diarrhoea (55%), prolonged antibiotic treatment (54%) or amoxicillin-clavulanic acid therapy (54%). Although current local guidelines recommend the use of selected probiotics in children receiving antibiotics in Asia-Pacific area, the rates of antibiotics and probiotics prescription significantly vary among countries and are deeply affected by country-related cultural and organisational issues.

Potency of Oral Rehydration Solution in Inducing Fluid Absorption is Related to Glucose Concentration

Oral rehydration solutions (ORSs) is the key treatment of acute diarrhea in children, as it restores the electrolyte balance by stimulating the intestinal sodium/glucose transporter SGLT1 to induce fluid absorption. The World Health Organization (WHO) and The European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) proposed ORSs with different chemical compositions. The main agent of childhood acute gastroenteritis is rotavirus (RV). We evaluate the effects of ORS with different concentration of glucose and sodium on RV induced secretion. Ussing chambers technique was used for electophysiology experiments to evaluate ion fluid flux. ESPGHAN ORS (sodium 60 mmol/L and glucose 111 mmol/L) induced a more potent proabsorptive effect in Caco-2 cells than WHO ORS, and this effect depended on the sodium/glucose ratio. Titration experiments showed that RV-induced fluid secretion can be reverted to a proabsorptive direction when sodium and glucose concentration fall in specific ranges, specifically 45–60 mEq/L and 80–110 mM respectively. The results were confirmed by testing commercial ORSs. These findings indicated that ORS proabsorptive potency depends on sodium and glucose concentrations. Optimal ORS composition should be tailored to reduce RV-induced ion secretion by also considering palatability. These in vitro data should be confirmed by clinical trials.

A comparative study of combined intravenous and topical administration of tranexamic acid with topical tranexamic acid alone for blood loss reduction after primary uncemented total hip arthroplasty

The aim of the present study was to evaluate the efficacy of topical versus combined (intravenous + topical) tranexamic acid (TXA) to reduce perioperative blood loss after uncemented primary total hip arthroplasty (THA). Seventy-five patients were randomized in three comparable experimental groups: 1) topical TXA (3 g in 50 ml of saline solution); 2) intravenous + topical TXA (3 g topical + 2 g in 100 ml of saline solution intravenously); 3) controls. Pre- and post-operative hemoglobin (Hb) levels and hematocrit (Hct) values along with the rate of blood transfusion in the 3 groups were compared. The intravenous + topical TXA group demonstrated higher Hb levels and Hct values at postoperative day one (Hb = p <0.05, Hct = p <0.001), postoperative day three (Hb = p <0.05, Hct = p <0.001), and discharge (Hct = p <0.01) compared to the control group. The intravenous + topical group had a lower transfusion rate compared to the control group (0% vs 20%, p = 0.014). With the numbers available, no difference in postoperative Hb level and transfusion rate emerged between topical TXA and control group.

Peritoneal tuberculosis mimicking carcinomatous ascites in a child living in a low prevalence country: a case report

BACKGROUND

Ascites can develop as a consequence of a number of diseases in childhood. Despite chronic liver disease is the most common cause, several conditions can lead to ascites also in the absence of liver dysfunction. As non-cirrhotic ascites shows a high degree of overlapping sign and symptoms it is still a challenge for physicians.

CASE PRESENTATION

A 8-year-old Caucasian girl was referred for fever, vomit and diarrhea occurred over the past few weeks. Physical examination showed timpanitic distension of the abdomen with marked tenderness and increased abdominal wall rigidity. Abdominal imaging showed diffuse ascites and thickened omentum and bowel wall. Blood tests showed increased C- reactive protein levels and decreased lymphocyte count. Specific treatment for inflammatory bowel disease was started. Persisting of ascites required additional investigations. Positive tuberculin skin test and Interferon Gamma release assay (IGRA) as well as increased Ca125 serum concentrations were found. Computed tomography scan showed mediastinal and mesenteric adenopathies and diffuse smooth thickening of the omentum with significant enhancement (omental cake-like). Ascitic fluid analysis revealed high leucocytes and protein levels. Presumptive diagnosis of peritoneal tuberculosis (PTB) was made. Antituberculous treatment resulted in the resolution of ascites and normalization of lymphocyte count and Ca125 serum concentrations.

CONCLUSIONS

PTB is still possible in low-prevalence countries. As it is a great mimicker of other abdominal pathology whose treatment might worsen tuberculosis progression, clinical suspicion and adequate screening are required to avoid unnecessary interventions and delayed treatment. Ca125 is a non-specific marker of peritoneal inflammation but it might be helpful in monitoring the treatment response.

The Transition of Care From Pediatric to Adult Health-Care Services of Vertically HIV-Infected Adolescents: A Pilot Study

Objective: Clinical and psychological HIV-related problems peak during adolescence, which coincides with transition of children and adolescents infected from mothers from pediatric to adult reference centers for HIV infection. Transition often is done without specific programs. We wanted to explore transition as an opportunity to increase the efficacy of care and the psychological well-being through a specific program. Methods: Thirteen vertically infected patients aged 13-20 years were followed up for 24 months by pediatricians, infectious disease specialists, a psychologist, and a nurse. Interventions consisted in joint clinic, simplification of therapy, patient group discussions, HIV infection explanations, and psychological support, lasting 12 months. Efficacy was measured by viro-immunological outcomes and adherence to therapy and psychological tests. Clinical, viro-immunological, and psychological evaluations were performed at 0 (T0) and 12 months (T12) and 6 months after transition to an adult center (T18). Psychological outcomes were assessed using standardized questionnaires for quality of life and self-esteem. Results: In 11/13 participants, pills administrations/day were significantly reduced. Patients with undetectable viral load and CD4+ >25% increased from 61 to 77% and from 61 to 74%, respectively. Six months after transition, all patients exhibited an undetectable viral load. Adolescents' awareness of the severity of the disease and the risk of sexual transmission was generally poor. Patients classified with "severe" psychological distress according to the quality of life index decreased from 38 to 15% and well-being increased. Similar results were observed 6 months after the transition to adult care. No effect was observed on self-esteem index. Conclusions: Specific protocols for transition should be developed to optimize resilience and psychological well-being, including routine psychological support for adolescents with HIV infection transiting from pediatric to adult centers for HIV infection.

Determinants of low measles vaccination coverage in children living in an endemic area

Measles outbreaks were recently reported in Europe due to low immunization rates. In this scenario, identifying the reasons of no vaccination is crucial to set up strategies to improve immunization rate. A cross-sectional study was conducted to investigate the determinants of missed vaccination in children living in Southern Italy, during the 2016 outbreak. A standardized face-to-face questionnaire was used to record demographic data, immunization status, and reasons for missed vaccination. A total of 1141 children (median age 86 months, male 47.2%) was enrolled, 77.8% of the children were adequately vaccinated for age, 6.3% were incompletely vaccinated for age, and 15.9% did not receive any vaccine dose. Vaccination rate and reasons for not vaccinating significantly varied according to age, with children ≤ 24 months showing the lowest rate (67.8%). Reasons for not vaccinating included fear for side effects (51%), presence of underlying chronic conditions (12.2%), skip scheduled appointment (12.2%), refusal of vaccination (10.3%), acute illnesses (7.2%), and allergy to eggs (4.6%). The presence of underlying condition was a risk factor for inadequate immunization (p < 0.0001). Only 4.7% of conditions were true contraindications to vaccine administration.Conclusion: We reported inadequate measles immunization rate in Southern Italy, with lowest rates in children ≤ 2 years or with underlying conditions. Only a minority had true contraindications to vaccine uptake. Implementation strategies addressed to health-care professionals and families should focus on the reported determinants to increase measles vaccination coverage. What is Known: • Measles is a viral, highly communicable disease, preventable by vaccine. • Measles elimination in Europe failed as demonstrated by outbreaks in several countries, due to low immunization rates. What is New: • Inadequate measles immunization rate due to false contraindications in Southern Italy, with lowest rates in children ≤ 2 years. • The presence of underlying disease is a risk factor for inadequate immunization.

Acute Infectious Diarrhea

Acute infectious diarrhea (AID) is one of the most common diseases in pediatric age with relevant burden both in high- and in low-income countries.Thanks to their direct action on enterocyte functions and indirect actions on mucosal and systemic immune system and intestinal microenvironment, probiotics are an ideal intervention to manage AID in childhood. However, their efficacy is strictly related to strains and indications, and practitioners should take this information into account in clinical practice.This chapter summarizes the main mechanisms of action of probiotics in AID, with a focus on proof of efficacy supporting their use in prevention and treatment of infant AID.The use of selected strains in appropriate doses is strongly recommended by guidelines of AID, based on large and consistent proofs of efficacy and safety. At present, therapy with probiotics of AID is arguably the strongest indication for probiotics in medicine. Future research should investigate probiotic efficacy in at-risk populations and settings where the evidence is missing.Their role in prevention of AID is however questionable in healthy population, whereas it should be considered in at-risk population. Evidence for prevention of diarrhea in day-care centers and communities is lacking, but consistent evidence supports efficacy in prevention of hospital acquired diarrhea.Overall, AID is the most convincing area for probiotic use in children, and effective strains should be used early after onset of symptoms.

Two cases of microvillous inclusion disease caused by novel mutations in MYO5B gene

Microvillous inclusion disease (MVID) typically appears with severe chronic diarrhea in the few days after birth and rapidly causes dehydration and metabolic acidosis. In this context, presenting two novel cases, we underline the crucial importance of mutation analysis for the diagnosis of this disease that may be easily misdiagnosed.

Dialogic reading in the rehabilitation of Children with Hearing Loss and the "Born to Read" Project: A pilot study

The "born to read" initiative entails a dialogic reading to children in poor socio-economical conditions aimed at fostering cognitive and relational skills. Reading is professionally delivered by experts to promote psycho-social development of children and their parents. In this study the project was extended to include children positive at early screening for hearing impairment. A total of 26 children were included and 14 parents were taught to read aloud and emphatically. Reading session were delivered for at least 10 minutes at least 3 times/week, usually at bedtime, for one year. The Griffiths scale were applied to explore the expressive and receptive language skills (Scale C) and eye and hand coordination (Scale D), as measures of linguistic and neurocognitive skills. Program sustainability and reactions by the parents were also investigated. All 14 families successfully received the training, becoming capable of reading aloud and emphatically and provided reading sessions for the entire duration of the study. Children receiving the intervention performed slightly better than controls and those who were exposed to increased number of sessions, performed even better although the differences with controls were not significant. Parents enjoyed reading to their children. They expressed satisfaction and gratitude for being able to play an active and productive role in children rehabilitation. The results of this pilot study suggest that the born to read initiative may be considered in adjunct to medical and psychological interventions to enhance the benefits of early screening of hearing function.

Altered intestinal microbiota composition, antibiotic therapy and intestinal inflammation in children and adolescents with cystic fibrosis

The aim of the present study was to evaluate the effect of cystic fibrosis and antibiotic therapy on intestinal microbiota composition and intestinal inflammation in children and adolescents. A cross-sectional controlled study was conducted with 36 children and adolescents: 19 in the cystic fibrosis group (CFG) and 17 in the control group (CG) matched for age and sex. The CFG was subdivided based on the use of antibiotic therapy (CFAB group) and non-use of antibiotic therapy (CFnAB group). The following data were evaluated: colonization, antibiotic therapy, mutation, breastfeeding, use of infant formula, type of delivery, introduction of solid foods, body mass index, fecal calprotectin and intestinal microbiota composition (fluorescence in situ hybridization). Intestinal inflammation evaluated by fecal calprotectin was significantly higher in the CFG (median: 40.80 µg/g, IQR: 19.80-87.10, p = 0.040) and CFAB group (median: 62.95 µg/g, IQR: 21.80-136.62, p = 0.045) compared to the CG (median: 20.15 µg/g, IQR: 16.20-31.00), and the Bacteroides, Firmicutes, Eubacterium rectale and Faecalibacterium prausnitzii were significantly decreased (p < 0.05) in the CFG compared to the CG, whereas the bacteria Clostridium difficile, Escherichia coli and Pseudomonas aeruginosa were significantly increased in the CFG (p < 0.05). The main differences were found between the CG and CFAB group for Eubacterium rectale (p = 0.006), Bifidobacterium (p = 0.017), Escherichia coli (p = 0.030), Firmicutes (p = 0.002), Pseudomonas aeruginosa (p < 0.001) and Clostridium difficile (p = 0.006). The results of this study confirm intestinal inflammation in patients with CF, which may be related to changes in the composition of the intestinal microbiota.

Pharmacokinetic drug evaluation of rifaximin for treatment of diarrhea-predominant irritable bowel syndrome

INTRODUCTION

Rifaximin is a poorly absorbable antibiotic with a broad-spectrum activity against both Gram-negative and -positive bacteria. It is active in the small intestine due to its high bile solubility, whereas in the aqueous environment of the colon, it shows limited efficacy against highly susceptible bacteria. These unique pharmacokinetic properties limit its systemic effects and can correct gut microflora imbalances. Thus, rifaximin has become a major therapeutic agent in several gastrointestinal diseases in which an imbalance in gut microflora may play a role, including diarrhea predominant irritable bowel syndrome (IBS-D). Area covered: This is an up-to-date review focusing on the efficacy of rifaximin in the treatment of IBS-D in both adult and pediatric populations. We will review the pharmacokinetic properties of rifaximin, including its absorption in health and disease, mechanisms of action, and interactions with other drugs. Expert opinion: Given its safety profile and its negligible absorption, rifaximin is a suitable treatment for IBS-D, in both adults and children. The possibility of modulating gut microbiota composition without side effects has made this drug an appealing therapeutic agent in highly prevalent gastrointestinal diseases. However, to date, monitoring for the development of resistant bacterial strains during long-term rifaximin use is still lacking.

Dolutegravir-based anti-retroviral therapy is effective and safe in HIV-infected paediatric patients

Background

Treatment of HIV infection in adolescents is challenging due to long duration of therapy and poor adherence. Recently, the integrase strand transfer inhibitor dolutegravir (DTG) has been approved for the use in adolescents with HIV, but evidence in clinical practice is very limited.

Methods

We describe six cases of HIV-infected children/adolescents successfully treated with DTG-based regimen. Data relative to children/adolescents managed at the Referral Center for Pediatric HIV/AIDS of the University of Naples were reviewed. Patients were tested before introduction of DTG, after 1 month and every 3 months in the first 2 years to assess virologic and immunological response, tolerance and development of side effects. Families were asked to report any suspected adverse events.

Results

Six patients (2 male, median age 17 years, range 12–18) were started on DTG-based anti-retroviral regimen due to low adherence to anti-retroviral treatment (ART), multiple drug resistance mutations, or development of ART-related side effects. Within 4–8 weeks after DTG treatment onset, a complete viral suppression and a concomitant increase of CD4⁺ cell count was observed. Four patients showed a persistent suppression after 2 years of follow-up, and 2 patients at about 1 year. One month after the introduction of DTG, the patient enrolled because of severe dyslipidaemia and hyper-transaminasemia showed a complete normalization of laboratory values. During follow-up (median 24 months, range 9–24) no adverse events were reported and most patients demonstrated a good adherence to treatment.

Conclusions

DTG-based treatments demonstrated efficacy and good safety profile in adolescents. All patients demonstrated a rapid virologic and immunological response within 4–8 weeks, with good adherence and absence of side effects.

Antibiotic treatment of acute gastroenteritis in children

Antibiotic therapy is not necessary for acute diarrhea in children, as rehydration is the key treatment and symptoms resolve generally without specific therapy. Searching for the etiology of gastroenteritis is not usually needed; however, it may be necessary if antimicrobial treatment is considered. The latter is left to the physician evaluation in the absence of clear indications. Antimicrobial treatment should be considered in severely sick children, in those who have chronic conditions or specific risk factors or in specific settings. Traveler’s diarrhea, prolonged diarrhea, and antibiotic-associated diarrhea may also require antibiotic therapy. Depending on the severity of symptoms or based on risk of spreading, empiric therapy may be started while awaiting the results of microbiological investigations. The choice of antibiotic depends on suspected agents, host conditions, and local epidemiology. In most cases, empiric therapy should be started while awaiting such results. Empiric therapy may be started with oral co-trimoxazole or metronidazole, but in severe cases parenteral treatment with ceftriaxone or ciprofloxacin might be considered.

Probiotics for gastrointestinal disorders: Proposed recommendations for children of the Asia-Pacific region

Recommendations for probiotics are available in several regions. This paper proposes recommendations for probiotics in pediatric gastrointestinal diseases in the Asia-Pacific region. Epidemiology and clinical patterns of intestinal diseases in Asia-Pacific countries were discussed. Evidence-based recommendations and randomized controlled trials in the region were revised. Cultural aspects, health management issues and economic factors were also considered. Final recommendations were approved by applying the Likert scale and rated using the GRADE system. Saccharomyces boulardii CNCM I-745 (Sb) and Lactobacillus rhamnosus GG (LGG) were strongly recommended as adjunct treatment to oral rehydration therapy for gastroenteritis. Lactobacillus reuteri could also be considered. Probiotics may be considered for prevention of (with the indicated strains): antibiotic-associated diarrhea (LGG or Sb); Clostridium difficile-induced diarrhea (Sb); nosocomial diarrhea (LGG); infantile colic (L reuteri) and as adjunct treatment of Helicobacter pylori (Sb and others). Specific probiotics with a history of safe use in preterm and term infants may be considered in infants for prevention of necrotizing enterocolitis. There is insufficient evidence for recommendations in other conditions. Despite a diversity of epidemiological, socioeconomical and health system conditions, similar recommendations apply well to Asia pacific countries. These need to be validated with local randomized-controlled trials.

European Society for Pediatric Gastroenterology Hepatology and Nutrition's Educational Offer and the Training Syllabus

The basic knowledge necessary for a European pediatric gastroenterologist/hepatologist/nutritionist is set-out in the training syllabus (TS) of the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN). We retrospectively compared the topics covered in ESPGHAN's training events between 2013 and 2016 with the basic knowledge TS items. Thirty-six initiatives including e-learning were identified. Twelve (33%) courses focused on gastroenterology, 9 (25%) on hepatology, and 10 (28%) on nutrition. Five (14%) courses covered >1 field and were classified "General." The initiatives covered 12 of 57 (21%) TS items; 31 of 57 items (54%) were partially covered; and 14 of 57 (25%) not covered. Five of 9 e-learning courses covered gastroenterology topics, whereas none covered hepatology topics. ESPGHAN's 3-year educational offer partially met the training needs listed in the TS. A coordinated educational program covering all TS items would harmonize training within Europe and would provide trainees with a professional portfolio for employment purposes.

Comparative effectiveness and impact on health-related quality of life of hysterectomy vs. levonorgestrel intra-uterine system for abnormal uterine bleeding

OBJECTIVE

To compare hysterectomy and levonorgestrel intra-uterine system (LNG-IUS) for the treatment of abnormal uterine bleeding (AUB) and iron deficiency anemia.

PATIENTS AND METHODS

Retrospective study evaluating quality of life, sexual function, satisfaction and blood hemoglobin concentration improvement in 60 pre-menopausal women treated with hysterectomy or LNG-IUS. All analysis was performed with statistical software SPSS 21.0 (SPSS Inc., Chicago, IL, USA).

RESULTS

Despite superior control of bleeding and dysmenorrhea observed after hysterectomy, LNG-IUS showed similar impact on blood hemoglobin levels, quality of life, satisfaction and sexual function resulting more cost-effective.

CONCLUSIONS

In the absence of contraindications, LNG-IUS should always be the first therapeutic choice for chronic AUB. Surgical treatment must be considered as an "extrema ratio".

Cervical carcinogenesis, bacterial vaginosis, HPV-mRNA test and relapse of CIN2+ after loop electrosurgical excision procedure (LEEP)

OBJECTIVE

The aim of the study was to evaluate the relationship between bacterial vaginosis (BV) and relapse of cervical intraepithelial neoplasia grade 2 or more (CIN2+) after Loop electrosurgical excision procedure (LEEP).

PATIENTS AND METHODS

One hundred four patients who underwent LEEP for CIN2+ were followed up every six months for three years. Fifty-three were negative for BV and fifty-one were positive. Each clinical control included Pap test, colposcopy, Amsel criteria test, HPV-DNA, and HPV-mRNA test.

RESULTS

Patients' age, presence of BV, positivity to HPV-DNA and HPV-mRNA tests were analyzed. The average age of patients was 42.5 ± 8.92 years (median: 42.5; range from 27 to 58 years). The minimum follow-up was 6 months and maximum 36 months (average: 22.8 ± 4.53; median: 24). The 10% of the patients with HPV-mRNA test negative had relapsed, compared to 45% of patients with HPV-mRNA test positive. Among the 53 patients without BV the 20% had relapsed compared with 23% of 51 patients with diagnosis of BV.

CONCLUSIONS

There is no evidence for higher percentage of relapse in patients with BV, submitted to excisional procedure for CIN2+ associated to HPV-m-RNA test positivity. There is only a correlation among BV and relapse of CIN2+ lesions after LEEP.

Mechanisms of antidiarrhoeal effects by diosmectite in human intestinal cells

Background

Rotavirus (RV) induces diarrhoea through a sequence of enterotoxic and cytotoxic effects. The former are NSP4-dependent, induce calcium-dependent chloride secretion and involve oxidative stress. Diosmectite (DS) is a natural clay that has been recommended as an active therapy for diarrhoea, but the mechanism of its effect is not clear. Electrical parameters may be used to measure the direct enterotoxic and cytotoxic effects in polar epithelial intestinal cells. To investigate the effects of DS on RV-induced enterotoxic and cytotoxic damage. Caco-2 cells were used as a model of RV infection to evaluate chloride secretion, epithelial integrity, oxidative stress and viral infectivity in Ussing chambers.

Results

Diosmectite reduced the expression of NSP4 and oxidative stress, resulting in a strong inhibition of chloride secretion. Preincubating RV with DS reduced the cytotoxic effect. Finally, the viral load was reduced by DS but not by control clay. This result suggests that DS specifically affects the early events of RV infection protecting the enterocyte, whereas it does not restore already-established cell damage.

Conclusion

These findings indicate that DS exerts an anti-diarrhoeal effect by inhibiting viral replication and the expression of NSP4. Both ion secretion and cell damage induced by RV are strongly inhibited consequent to the antiviral effect, which explains its clinical efficacy.

Rotavirus immunization: Global coverage and local barriers for implementation

BACKGROUND

Rotavirus (RV) is a major agent of gastroenteritis and an important cause of child death worldwide. Immunization (RVI) has been available since 2006, and the Federation of International Societies of Gastroenterology Hepatology and Nutrition (FISPGHAN) identified RVI as a top priority for the control of diarrheal illness. A FISPGHAN working group on acute diarrhea aimed at estimating the current RVI coverage worldwide and identifying barriers to implementation at local level.

METHODS

A survey was distributed to national experts in infectious diseases and health-care authorities (March 2015-April 2016), collecting information on local recommendations, costs and perception of barriers for implementation.

RESULTS

Forty-nine of the 79 contacted countries (62% response rate) provided a complete analyzable data. RVI was recommended in 27/49 countries (55%). Although five countries have recommended RVI since 2006, a large number (16, 33%) included RVI in a National Immunization Schedule between 2012 and 2014. The costs of vaccination are covered by the government (39%), by the GAVI Alliance (10%) or public and private insurance (8%) in some countries. However, in most cases, immunization is paid by families (43%). Elevated cost of vaccine (49%) is the main barrier for implementation of RVI. High costs of vaccination (rs=-0.39, p=0.02) and coverage of expenses by families (rs=0.5, p=0.002) significantly correlate with a lower immunization rate. Limited perception of RV illness severity by the families (47%), public-health authorities (37%) or physicians (24%) and the timing of administration (16%) are further major barriers to large- scale RVI programs.

CONCLUSIONS

After 10years since its introduction, the implementation of RVI is still unacceptably low and should remain a major target for global public health. Barriers to implementation vary according to setting. Nevertheless, public health authorities should promote education for caregivers and health-care providers and interact with local health authorities in order to implement RVI.

Gelatin tannate and tyndallized probiotics: a novel approach for treatment of diarrhea

OBJECTIVE

Intestinal permeability impairment is implicated in many gastrointestinal (GI) diseases. Chronic diarrhea, defined as the presence of diarrhea for more than 3 weeks in adults and 2 weeks in children, requires a different diagnostic and therapeutic work-up than acute diarrhea. Gelatin tannate, by reducing the clinical activity of acute colitis and the proinflammatory effects of lipopolysaccharide (LPS), is emerging as a mucosal barrier protector.

MATERIALS AND METHODS

New therapeutic strategies focusing on the physiological function of the intestinal barrier, may offer an innovative approach for the clinical improvement of highly debilitating chronic GI diseases. We review the available data on the role of gelatin tannate and tyndallized probiotics in the treatment of diarrhea.

RESULTS

Gelatin tannate and tyndallized probiotics can be used to re-establish the physiological functions of the gut barrier, as well as for preventing dysbiosis. There is evidence that due to their particular properties, gelatin tannate and tyndallized probiotics are highly effective in the treatment of acute gastroenteritis and may be especially indicated in the management of moderate and prolonged diarrhea.

CONCLUSIONS

Gelatin tannate and tyndallized probiotics may be effective in the management of chronic diarrhea. Further clinical trials are necessary to further explore their effects in clinical practice.

Recommendations for the diagnosis of pediatric tuberculosis

Tuberculosis (TB) is still the world's second most frequent cause of death due to infectious diseases after HIV infection, and this has aroused greater interest in identifying and managing exposed subjects, whether they are simply infected or have developed one of the clinical variants of the disease. Unfortunately, not even the latest laboratory techniques are always successful in identifying affected children because they are more likely to have negative cultures and tuberculin skin test results, equivocal chest X-ray findings, and atypical clinical manifestations than adults. Furthermore, they are at greater risk of progressing from infection to active disease, particularly if they are very young. Consequently, pediatricians have to use different diagnostic strategies that specifically address the needs of children. This document describes the recommendations of a group of scientific societies concerning the signs and symptoms suggesting pediatric TB, and the diagnostic approach towards children with suspected disease.

Impact of cystic fibrosis disease on archaea and bacteria composition of gut microbiota

Cystic fibrosis is often associated with intestinal inflammation due to several factors, including altered gut microbiota composition. In this study, we analyzed the fecal microbiota among patients with cystic fibrosis of 10–22 years of age, and compared the findings with age-matched healthy subjects. The participating patients included 14 homozygotes and 14 heterozygotes with the delF508 mutation, and 2 heterozygotes presenting non-delF508 mutations. We used PCR-DGGE and qPCR to analyze the presence of bacteria, archaea and sulfate-reducing bacteria. Overall, our findings confirmed disruption of the cystic fibrosis gut microbiota. Principal component analysis of the qPCR data revealed no differences between homozygotes and heterozygotes, while both groups were distinct from healthy subjects who showed higher biodiversity. Archaea were under the detection limit in all homozygotes subjects, whereas methanogens were detected in 62% of both cystic fibrosis heterozygotes and healthy subjects. Our qPCR results revealed a low frequency of sulfate-reducing bacteria in the homozygote (13%) and heterozygote (13%) patients with cystic fibrosis compared with healthy subjects (87.5%). This is a pioneer study showing that patients with cystic fibrosis exhibit significant reduction of H₂-consuming microorganisms, which could increase hydrogen accumulation in the colon and the expulsion of this gas through non-microbial routes.

Clostridium difficile infection in children: epidemiology and risk of recurrence in a low-prevalence country

Clostridium difficile infection (CDI) is increasingly found in children worldwide, but limited data are available from children living in southern Europe. A 6-year retrospective study was performed to investigate the epidemiology, clinical features, treatment, and risk of recurrence in Italy. Data of children with community- and hospital-acquired CDI (CA-CDI and HA-CDI, respectively) seen at seven pediatric referral centers in Italy were recorded retrospectively. Annual infection rates/10,000 hospital admissions were calculated. Logistic regression was used to investigate risk factors for recurrence. A total of 177 CDI episodes was reported in 148 children (83 males, median age 55.3 months), with a cumulative infection rate of 2.25/10,000 admissions, with no significant variability over time. The majority of children (60.8 %) had CA-CDI. Children with HA-CDI (39.2 %) had a longer duration of symptoms and hospitalization (p = 0.003) and a more common previous use of antibiotics (p = 0.0001). Metronidazole was used in 70.7 % of cases (87/123) and vancomycin in 29.3 % (36/123), with similar success rates. Recurrence occurred in 16 children (10.8 %), and 3 (2 %) of them presented a further treatment failure. The use of metronidazole was associated with a 5-fold increase in the risk of recurrence [odds ratio (OR) 5.18, 95 % confidence interval (CI) 1.1-23.8, p = 0.03]. Short bowel syndrome was the only underlying condition associated with treatment failure (OR 5.29, 95 % CI 1.17-23.8, p = 0.03). The incidence of pediatric CDI in Italy is low and substantially stable. In this setting, there is a limited risk of recurrence, which mainly concerns children treated with oral metronidazole and those with short bowel syndrome.

Randomised clinical trial: a Lactobacillus GG and micronutrient-containing mixture is effective in reducing nosocomial infections in children, vs. placebo

BACKGROUND

Nosocomial infections are a major public health issue and preventative strategies using probiotics and micronutrients are being evaluated.

AIM

To investigate the efficacy of a mixture of Lactobacillus GG and micronutrients in preventing nosocomial infections in children.

METHODS

A randomised, double-blind, placebo-controlled trial was conducted in hospitalised children. Children (6 months to 5 years of age) received Lactobacillus GG (6 × 10(9) CFU/day) together with vitamins B and C and zinc or placebo, for 15 days, starting on the first day of hospitalisation. The incidence of gastrointestinal and respiratory nosocomial infections after discharge was determined by follow-up telephone call at 7 days. After 3 months, another telephone call estimated the incidence of further infections during follow-up.

RESULTS

Ninety children completed the follow-up. Of 19/90 children with a nosocomial infection (20%), 4/45 children (9%) were in the treatment group and 15/45 (33%) in the placebo group (P = 0.016). Specifically, 2/45 (4%) children in the treatment group vs. 11/45 (24%) children in the placebo group (P = 0.007) presented with diarrhoea. The duration of hospitalisation was significantly shorter in the treatment group (3.9 days ± 1.7 vs. 4.9 ± 1.2; P = 0.003). At the follow-up, a total of 11/45 (24.4%) children in the treatment group had at least one episode of infection compared to 22/45 (48.9%) in the placebo group (P = 0.016).

CONCLUSION

A mixture containing Lactobacillus GG and micronutrients may reduce the incidence of nosocomial infections, supporting the hypothesis that this may represent a valid strategy to prevent nosocomial infections.

Human papilloma virus infection and cervical cytomorphological changing among intrauterine contraception users

OBJECTIVE

The increased use of the intrauterine contraception (IUC) in female population and its probable relationship with cervical squamous intraepithelial lesions and cervical cancer make necessary clarify the possible interaction between the device and the pre-neoplastic lesions.

PATIENTS AND METHODS

Seven hundred and eighty-nine patients users of IUC and 1491 patients ever users of IUC were followed every 6 months for 3 years. Each clinical control included Papanicolau test, colposcopy, HPV-DNA test and HPV-mRNA test. Also, in patients IUC users we analyzed the type of device, years of use and average age.

RESULTS

Cytological sampling, histological examination, HPV-DNA test and HPV-mRNA test showed that there are not significantly differences between patients with or without IUC.

CONCLUSIONS

None difference arose regarding persistence and progression between patients IUC users and IUC no users, for this reason, intrauterine contraception does not seem to be a co-causal factor in the possible development of cervical cancer.

An international consensus report on a new algorithm for the management of infant diarrhoea

AIM

Implementing international guidelines guarantees high standards of clinical care. A group of experts developed an algorithm to drive the management of common gastrointestinal symptoms in infancy by paediatricians and general practitioners.

METHODS

The algorithm started from the evidence-based recommendations of the European Society of Gastroenterology, Hepatology and Nutrition and the European Society of Pediatric Infectious Diseases and an updated review of the literature. We used the structured quantitative method of nominal group technique to reach a consensus.

RESULTS

A practical algorithm for the management of infants with acute diarrhoea was designed based on the consensus reached for each statement. The management of an infant with acute diarrhoea should include a sequence of actions: (i) a semiquantitative estimate of infant dehydration through validated clinical scores, (ii) rehydration therapy and early refeeding with breast milk or regular formula and (iii) effective agents to reduce the severity and duration of the diarrhoea. Finally, in children with prolonged diarrhoea, the search for aetiology should include persistent infections or reinfections, cows' milk protein allergy and coeliac diseases. Lactose should always be withdrawn.

CONCLUSION

This algorithm provides an evidence-based sequence of interventions to optimise the management of infants with acute diarrhoea.

Gastrointestinal and liver infections in children undergoing antineoplastic chemotherapy in the years 2000

AIM: To review gastrointestinal and liver infections in children undergoing antineoplastic chemotherapy. To look at gut microflora features in oncology children.

METHODS: We selected studies published after year 2000, excluding trials on transplanted pediatric patients. We searched English language publications in MEDLINE using the keywords: “gastrointestinal infection AND antineoplastic chemotherapy AND children”, “gastrointestinal infection AND oncology AND children”, “liver infection AND antineoplastic chemotherapy AND children”, “liver abscess AND chemotherapy AND child”, “neutropenic enterocolitis AND chemotherapy AND children”, “thyphlitis AND chemotherapy AND children”, “infectious diarrhea AND children AND oncology”, “abdominal pain AND infection AND children AND oncology”, “perianal sepsis AND children AND oncology”, “colonic pseudo-obstruction AND oncology AND child AND chemotherapy”, “microflora AND children AND malignancy”, “microbiota AND children AND malignancy”, “fungal flora AND children AND malignancy”. We also analysed evidence from several articles and book references.

RESULTS: Gastrointestinal and liver infections represent a major cause of morbidity and mortality in children undergoing antineoplastic chemotherapy. Antineoplastic drugs cause immunosuppression in addition to direct toxicity, predisposing to infections, although the specific risk is variable according to disease and host features. Common pathogens potentially induce severe diseases whereas opportunistic microorganisms may attack vulnerable hosts. Clinical manifestations can be subtle and not specific. In addition, several conditions are rare and diagnostic process and treatments are not standardized. Diagnosis may be challenging, however early diagnosis is needed for quick and appropriate interventions. Interestingly, the source of infection in those children can be exogenous or endogenous. Indeed, mucosal damage may allow the penetrance of endogenous microbes towards the bowel wall and their translocation into the bloodstream. However, only limited knowledge of intestinal dysbiosis in oncology children is available.

CONCLUSION: The diagnostic work-up requires a multimodal approach and should be implemented (also by further studies on new biomarkers) for a prompt and individualized therapy.

Reduced central line infection rates in children with leukemia following caregiver training: A quality improvement study

Infections are a leading cause of morbidity and mortality in children with acute leukemia. Central-line (CL) devices increase this population's risk of serious infections.Within the context of a quality improvement (QI) project, we tested the effect of caregiver education on CL management on the CL-associated bloodstream infection (CLABSI) rate among children with acute leukemia seen at a large referral center in Italy. The intervention consisted of 9 in-person sessions for education and practice using mannequins and children.One hundred and twenty caregivers agreed to participate in the initiative. One hundred and five (87.5%) completed the training, 5 (4.1%) withdrew after the first session, and 10 (8.3%) withdrew during practical sessions. After educational intervention, the overall CLABSI rate was reduced by 46% (from 6.86 to 3.70/1000 CL-days). CLABSI rate was lower in children whose caregivers completed the training (1.74/1000 CL-days, 95% CI 0.43-6.94) compared with those who did not receive any training (12.2/1000 CL-days, 95% CI 7.08-21.0, P < 0.05) or were in-training (3.96/1000 CL-days, 95% CI 1.98-7.91) at the time of infection.Caregiver training in CL management, applied within a multifaceted QI approach, reduced the rate of CLABSI in children with acute leukemia. Specific training and active involvement of caregivers in CL management may be effective to reduce CLABSI in high-risk children.

Antibiotic Prescriptions and Prophylaxis in Italian Children. Is It Time to Change? Data from the ARPEC Project

BACKGROUND

Antimicrobials are the most commonly prescribed drugs. Many studies have evaluated antibiotic prescriptions in the paediatric outpatient but few studies describing the real antibiotic consumption in Italian children's hospitals have been published. Point-prevalence survey (PPS) has been shown to be a simple, feasible and reliable standardized method for antimicrobials surveillance in children and neonates admitted to the hospital. In this paper, we presented data from a PPS on antimicrobial prescriptions carried out in 7 large Italian paediatric institutions.

METHODS

A 1-day PPS on antibiotic use in hospitalized neonates and children was performed in Italy between October and December 2012 as part of the Antibiotic Resistance and Prescribing in European Children project (ARPEC). Seven institutions in seven Italian cities were involved. The survey included all admitted patients less than 18 years of age present in the ward at 8:00 am on the day of the survey, who had at least one on-going antibiotic prescription. For all patients data about age, weight, underlying disease, antimicrobial agent, dose and indication for treatment were collected.

RESULTS

The PPS was performed in 61 wards within 7 Italian institutions. A total of 899 patients were eligible and 349 (38.9%) had an on-going prescription for one or more antibiotics, with variable rates among the hospitals (25.7% - 53.8%). We describe antibiotic prescriptions separately in neonates (<30 days old) and children (> = 30 days to <18 years old). In the neonatal cohort, 62.8% received antibiotics for prophylaxis and only 37.2% on those on antibiotics were treated for infection. Penicillins and aminoglycosides were the most prescribed antibiotic classes. In the paediatric cohort, 64.4% of patients were receiving antibiotics for treatment of infections and 35.5% for prophylaxis. Third generation cephalosporins and penicillin plus inhibitors were the top two antibiotic classes. The main reason for prescribing antibiotic therapy in children was lower respiratory tract infections (LRTI), followed by febrile neutropenia/fever in oncologic patients, while, in neonates, sepsis was the most common indication for treatment. Focusing on prescriptions for LRTI, 43.3% of patients were treated with 3rd generation cephalosporins, followed by macrolides (26.9%), quinolones (16.4%) and carbapenems (14.9%) and 50.1% of LRTI cases were receiving more than one antibiotic. For neutropenic fever/fever in oncologic patients, the preferred antibiotics were penicillins with inhibitors (47.8%), followed by carbapenems (34.8%), aminoglycosides (26.1%) and glycopeptides (26.1%). Overall, the 60.9% of patients were treated with a combination therapy.

CONCLUSIONS

Our study provides insight on the Italian situation in terms of antibiotic prescriptions in hospitalized neonates and children. An over-use of third generation cephalosporins both for prophylaxis and treatment was the most worrisome finding. A misuse and abuse of carbapenems and quinolones was also noted. Antibiotic stewardship programs should immediately identify feasible targets to monitor and modify the prescription patterns in children's hospital, also considering the continuous and alarming emergence of MDR bacteria.

Regulation of Stearoyl Coenzyme A Desaturase 1 Gene Promoter in Bovine Mammary Cells

Stearoyl-Coenzyme A desaturase 1 (SCD1) belongs to the fatty acid family of desaturases. In lactating ruminants, the SCD1 protein is highly expressed in the mammary gland and is relevant for the fatty acid composition of milk and dairy products. Bovine mammary epithelial cells (BME-UV1), cultured in vitro, have been proposed as a model to reproduce the biology of the mammary gland. The present study was designed to investigate the responsiveness of bovine SCD1 promoter to serum, insulin, oleic acid, and NFY transcription factor in BME-UV1 cells. A luciferase-based reporter assay was used to monitor the transcriptional activity of the SCD1 promoter region in BME-UV1 cells treated or not with insulin and/or oleic acid. The level of endogenous SCD1 mRNA was evaluated by Real time PCR. Insulin (20 ng/mL) induced a 2.0 to 2.5-fold increase of SCD1 promoter activity. Additionally, the effect of insulin was inhibited by oleic acid, serum components, and NFY enforced expression. Serum and NFY showed no synergistic or additive effect on SCD1 promoter activity suggesting that they repress SCD1 transcription through the same responsive element.

Developing a core outcome measurement set for clinical trials in acute diarrhoea

AIM

The Working Group on Acute Diarrhoea, part of The Consensus Group on Outcome Measures Made in Paediatric Enteral Nutrition Clinical Trials, previously developed a core outcome set for clinical trials on acute diarrhoea. This study aimed to create a core outcome measurement set to complement it.

METHODS

The study had three phases. The first identified how the literature defined core outcome measures in clinical trials on acute diarrhoea and measured outcomes. The second phase used a questionnaire to seek the views of 109 leading researchers and clinicians in this specialist field. The third phase achieved a consensus on the core outcome measurement set.

RESULTS

First, we identified 52 different measurement instruments or definitions. A questionnaire was then used to ask our experts what they thought were the most valid core outcome measurement instruments or definitions for each measure and 53 (49%) responded. Core outcome measurement instruments were then developed, including definitions of diarrhoea and acute gastroenteritis, diarrhoea duration, dehydration, the need for hospitalisation, discharge criteria and duration of hospitalisation.

CONCLUSION

The outcome measurement set can be used to evaluate therapeutic or preventive strategies and can be recommended for use in future acute diarrhoea trials.

Functional gastro-intestinal disorder algorithms focus on early recognition, parental reassurance and nutritional strategies

Up to 50% of infants present with symptoms of regurgitation, infantile colic and/or constipation during the first 12 months of life. Although they are often classed as functional disorders, there is an overlap with cows' milk allergy. We present practical algorithms for the management of such disorders, based on existing evidence and general consensus, with a particular focus on primary health care. Management consists of early recognition of warning signs of organic disease, parental reassurance and nutritional strategies.

CONCLUSION

The proposed algorithms aim to help healthcare providers manage frequent gastrointestinal and cows' milk-related symptoms in infants safely and effectively.

Management of children with prolonged diarrhea

Prolonged diarrhea is usually defined as acute-onset diarrhea lasting 7 days or more, but less than 14 days. Its trend has been declining in recent years because of improvement in the management of acute diarrhea, which represents the ideal strategy to prevent prolonged diarrhea. The pathogenesis of prolonged diarrhea is multifactorial and essentially based on persistent mucosal damage due to specific infections or sequential infections with different pathogens, host-related factors including micronutrient and/or vitamin deficiency, undernutrition and immunodeficiency, high mucosal permeability due to previous infectious processes and nutrient deficiency with consequential malabsorption, and microbiota disruption. Infections seem to play a major role in causing prolonged diarrhea in both developing and developed areas. However, single etiologic pathogens have not been identified, and the pattern of agents varies according to settings, host risk factors, and previous use of antibiotics and other drugs. The management of prolonged diarrhea is complex. Because of the wide etiologic spectrum, diagnostic algorithms should take into consideration the age of the patient, clinical and epidemiological factors, and the nutritional status and should always include a search for enteric pathogens. Often, expensive laboratory evaluations are of little benefit in guiding therapy, and an empirical approach may be effective in the majority of cases. The presence or absence of weight loss is crucial for driving the initial management of prolonged diarrhea. If there is no weight loss, generally there is no need for further evaluation. If weight loss is present, empiric anti-infectious therapy or elimination diet may be considered once specific etiologies have been excluded.

Indications to Hospital Admission and Isolation of Children With Possible or Defined Tuberculosis: Systematic Review and Proposed Recommendations for Pediatric Patients Living in Developed Countries. [Corrected]

Tuberculosis (TB) is a re-emerging health problem in developed countries. This paper is part of large guidelines on the global management of TB in children, by a group of scientific societies. It describes the indications to hospitalization of children with suspected or diagnosed TB, the isolation measures, hospital discharge, and re-admission into the community. Using the Consensus Conference method, relevant publications in English were identified by means of a systematic review of MEDLINE and the Cochrane Database of Systematic Reviews from their inception until 31 December 2014. Available data on indications to hospitalization were mainly indirect and largely derived from observational studies. They include: (1) host-related risk factors, the main being age <12 months, immune deficiencies, and malnutrition; (2) TB-related clinical conditions that resemble those of pneumonia but also include drug-resistance; and (3) social and logistic conditions. The latter are based on opinion and depend on local conditions. Analysis of the literature showed that patients hospitalized with suspected pulmonary TB should be put in precautionary respiratory isolation regardless of their age while they await diagnosis. The general conditions for re-admission into the community are at least 14 days of effective treatment and negative microscopic tests of 3 consecutive samples in previously microscopically positive patients. This is the first paper that provides indications to hospitalization of children with TB. Most recommendations are generally applicable in all developed countries. Some might need an adaptation to local setting, epidemiological, parameters, and availability of specific health-care facilities.

How to manage children who have come into contact with patients affected by tuberculosis

Childhood tuberculosis (TB) indicates a recent infection, particularly in children aged < 5 years, and therefore is considered a sentinel event insofar as it highlights the presence of an undiagnosed or untreated source case. The risk of acquiring TB is directly proportional to the number of bacilli to which a subject is exposed and the environment in which the contact occurred. This document contains the recommendations of a group of Italian scientific societies for managing a child exposed to a case of TB based on an analysis of the risk factors for acquiring latent tuberculous infection (LTBI) and developing the disease, and the particular aspects TB transmission during the first years of life. The guidance includes a detailed description of the methods used to identify the index case, the tests that the exposed child should receive and the possibilities of preventive chemoprophylaxis depending on the patient's age and immune status, the chemotherapy and monitoring methods indicated in the case of LTBI, the management of a child who has come into contact with a case of multidrug-resistant or extensively drug-resistant TB, and the use of molecular typing in the analysis of epidemics. The group of experts identified risk factors for tuberculous infection and disease in pediatric age as well as gave recommendation on management of contacts of cases of TB according to their age, risk factors and exposure to multidrug-resistant or extensively drug-resistant TB.

Sustained low influenza vaccination in health care workers after H1N1 pandemic: a cross sectional study in an Italian health care setting for at-risk patients

Background

Despite consistent recommendations by all Public Health Authorities in support of annual influenza vaccination for at-risk categories, there is still a low uptake of influenza vaccine in these groups including health care workers (HCWs). Aim of this observational two-phase study was to estimate the immunization rates for influenza in four subsequent seasons and for pandemic H1N1 influenza in HCWs of a University Hospital, and to investigate its distribution pattern and the main determinants of immunization. Phase 1 data collection was performed in 2009–2010, during the peak of H1N1 pandemic. Phase 2 data collection, aimed to investigate seasonal influenza vaccination coverage in the three seasons after pandemic, was performed in 2012–2013.

Methods

The overall H1N1 vaccination rate was derived by the Hospital immunization registry. In 2010, the personnel of three Departments (Infectious Diseases, Pediatrics and Gynecology/Obstetrics) completed a survey on influenza. A second-phase analysis was performed in 2012 to investigate influenza vaccination coverage in three consecutive seasons.

Results

The first-phase survey showed a low coverage for influenza in all categories (17 %), with the lowest rate in nurses (8.1 %). A total of 37 % of health care workers received H1N1 vaccine, with the highest rate among physicians and the lowest in nurses. H1N1 vaccination was closely related to the Department, being higher in the Department of Infectious Diseases (53.7 %) and Pediatrics (42.4 %) than in Gynecology/Obstetrics (8.3 %). The second-phase survey showed the lowest rate of influenza vaccination in 2012/13 season. The main reasons for not being vaccinated were “Unsure of the efficacy of vaccine” and “Feel not at-risk of getting influenza or its complications”. Despite recommendations, influenza vaccine uptake remains poor.

Conclusion

Immunization is largely perceived as a personal protection rather than a measure needed to prevent disease spreading to at-risk patients. Compulsory vaccination against influenza should be considered as a possible strategy, at least in health institutions where at-risk patients are admitted.

The Impact of E-Learning on Adherence to Guidelines for Acute Gastroenteritis: A Single-Arm Intervention Study

Objective

E-learning is a candidate tool for clinical practice guidelines (CPG) implementation due to its versatility, universal access and low costs. We aimed to assess the impact of a five-module e-learning course about CPG for acute gastroenteritis (AGE) on physicians’ knowledge and clinical practice.

Study design

This work was conceived as a pre/post single-arm intervention study. Physicians from 11 European countries registered for the online course. Personal data, pre- and post-course questionnaires and clinical data about 3 to 5 children with AGE managed by each physician before and after the course were collected. Primary outcome measures included the proportion of participants fully adherent to CPG and number of patients managed with full adherence.

Results

Among the 149 physicians who signed up for the e-learning course, 59 took the course and reported on their case management of 519 children <5 years of age who were referred to their practice because of AGE (281 and 264 children seen before and after the course, respectively). The course improved knowledge scores (pre-course 8.6 ± 2.7 versus post-course 12.8 ± 2.1, P < 0.001), average adherence (from 87.0 ± 7.7% to 90.6 ± 7.1%, P = 0.001) and the number of patients managed in full adherence with the guidelines (from 33.6 ± 31.7% to 43.9 ± 36.1%, P = 0.037).

Conclusions

E-learning is effective in increasing knowledge and improving clinical practice in paediatric AGE and is an effective tool for implementing clinical practice guidelines.

Subradiological cam deformity of the head-neck junction: an occult cause of hip pain and chondrolabral damage

PURPOSE

The goal of this study was to determine how frequently the conventionally defined "idiopathic" chondrolabral hip injuries are associated with subradiological cam deformities of the head-neck junction and whether a protective femoral osteochondroplasty may improve the outcome of their arthroscopic treatment.

METHODS

All the non-arthritic or pre-arthritic painful hips diagnosed as having a primary chondrolabral injury were retrospectively evaluated. Coxometric data, clinical history and physical findings were reviewed to rule out any possible secondary lesion. The medical records of the selected cases were analyzed as for imaging features, surgical findings and post-arthroscopy outcome.

RESULTS

Three cases out of 79 chondrolabral injuries were identified as "primary" on the basis of the preoperative assessment. All the three patients were female in their fourth decade and showed a joint damage consistent with undetected cam FAI (cartilage delamination in the anterolateral acetabular quadrant, minor pathology of the adjacent labrum with or without chondrolabral separation, abrasion signs and herniation pits along the anterolateral head-neck junction). The first patient received a simple chondrolabral treatment whose benefits deteriorated few months after surgery; the second patient underwent chondrolabral repair and femoral osteochondroplasty and is still pain-free; and the third patient had a beneficial revision arthroscopy for femoral osteochondroplasty after prior unsuccessful chondrolabral surgery.

CONCLUSIONS

If a chondrolabral injury of the hip is associated with MR arthrographic and arthroscopic indirect signs of cam FAI, a subradiological head-neck deformity should be considered despite normal alpha angles. In such cases, a protective femoral osteochondroplasty may increase the success rate of the chondrolabral repair.

A core outcome set for clinical trials in acute diarrhoea

OBJECTIVE

Core outcome sets are the baseline for what should be measured in clinical research and, thus, should serve as a guide for what should be collected and reported. The Consensus Group on Outcome Measures Made in Pediatric Enteral Nutrition Clinical Trials, established in 2012, agreed that consensus on a core set of outcomes with agreed-upon definitions that should be measured and reported in clinical trials was needed. To achieve this goal, six working groups (WGs) were setup, including WG on acute diarrhoea, whose main goal was to develop a core outcome set for trials in acute diarrhoea.

METHODS

The first step identified how published outcomes related to acute diarrhoea were reported. The second focused on the methodology for determining which outcomes to measure in clinical trials. The third employed a two-phase questionnaire study using the Delphi technique to define clinically important outcomes to clinicians and parents.

RESULTS

For therapeutic studies, the five most important outcome measures were diarrhoea duration, degree of dehydration, need for hospitalisation (or duration of hospitalisation for inpatients), the proportion of patients recovered by 48 h and adverse effects. The prophylactic core outcome set included prevention of diarrhoea, prevention of dehydration, prevention of hospitalisation and adverse effects.

CONCLUSIONS

The outcome sets for therapy and prevention can be recommended for use in future trials of patients with gastroenteritis. Their envisioned goal is to decrease study heterogeneity and to ease the comparability of studies. WG's next step is to determine how to measure the outcomes included in the core set.
