Feeding difficulties in children with esophageal atresia: treatment by a multidisciplinary team

Esophageal atresia (EA) is one of the congenital neonatal anomalies whose immediate consequence for the newborn is the inability to feed. Most centers strive to minimize the effects of surgeries and subsequent postoperative complications such as esophageal strictures, respiratory problems, and gastrointestinal reflux on the child's ability or motivation to feed. Feeding difficulties in early infancy may not only interrupt maternal expectations of becoming providers of nutrition to their infants but may also influence the infant's development of sensory motor skills and parent-child relationships. Early involvement by a multidisciplinary team consisting of occupational therapist, nutritionist, and psychologist is an important addition to the surgical and medical team. The team assists in preparing mothers for feeding-related difficulties, providing anticipatory guidance to improve feeding abilities and relationships, especially for children with multiple surgical involvements and prolonged periods of non-oral feeding.

An unusual transmission event of Neisseria meningitidis serogroup W135 type 2a in a healthcare setting, England, 2012

We report an outbreak of Neisseria meningitidis serogroup W135, associated with a transient transmission event between asymptomatic individuals in a healthcare setting. Two elderly persons subsequently developed invasive meningococcal disease. The duration and type of close contact for those directly involved in the probable transmission incident would not have warranted chemoprophylaxis according to current guidelines. Meningococcal infection in older persons usually presents with pneumonia rather than meningitis or septicaemia with purpura.

Measuring childhood vaccine coverage in England: the role of Child Health Information Systems

Child Health Information Systems (CHISs) are computerised clinical record systems which support a range of health promotion and prevention activities for children, including immunisation and screening. There are a number of different providers of CHISs in England. These systems are managed by child health departments in each local area and not all are interoperable. The establishment of systems which record and maintain accurate information on the entire population is critical to assess vaccination coverage at both national and local levels. These systems should have the flexibility to adapt to a continuously evolving immunisation programme, a mechanism to rapidly feedback to local public health teams for outbreak prevention and control, and the ability to mount a timely response to vaccine safety scares. The ability to schedule (call and recall) immunisation appointments has contributed to improvements in vaccination coverage both in England and elsewhere. While this has been achieved in England through multiple CHISs the development of a single national register would reduce the complexities of maintaining accurate and complete immunisation records for the entire population.

A cluster of four cases of meningococcal disease in a single nuclear family

A cluster of four confirmed cases of meningococcal disease was seen in the same nuclear family across a 15-week period. The cases were three siblings and a parent and all recovered well. The first case was confirmed by meningococcal PCR only but the subsequent three cases were due to indistinguishable strains of serogroup B (B:NT:P1.19-1,15-11). Contact tracing was initially undertaken and reviewed in detail after each subsequent case. Antibiotic prophylaxis was administered to close family contacts on three separate occasions, including switching of antibiotic agents, with good compliance. Subsequent investigation of the family has not revealed any obvious immunological problem and no further significant infections have been recognised. A cluster of meningococcal disease of this nature and timescale is highly unusual. Details of the cluster, investigation and implications for health protection practice are discussed.

A possible outbreak of hepatitis A associated with semi-dried tomatoes, England, July–November 2011

In October 2011, two primary cases of hepatitis A virus (HAV) infection with identical HAV genotype IB strains to those seen in other outbreaks associated with semi-dried tomatoes were reported in England. Both cases had consumed semi-dried tomatoes. Epidemiological investigations revealed two additional cases of genotype IB strains with different sequences who also reported having consumed semi-dried tomatoes. In November, five cases of HAV infection with closely related strains were identified in the Netherlands. A foodborne multiple-strain outbreak is suspected.

The impact of mode of acquisition on biological markers of paediatric hepatitis C virus infection

Despite the introduction of blood donor screening, worldwide, children continue to become infected with hepatitis C virus (HCV) via un-sterile medical injections, receipt of unscreened blood and isolated hospital contamination outbreaks. It is plausible that the natural history and disease progression in these children might differ from that of their vertically infected counterparts. Vertically and parenterally HCV-infected children were prospectively followed within the European Paediatric HCV Network and the UK National HCV Register, respectively. Biological profiles were compared. Vertically and parenterally HCV-infected children differed in terms of some key characteristics including the male to female ratio and the proportion of children receiving therapy. Parenterally infected children were more likely to have at least one hepatomegaly event during follow-up, 20%vs 10%. Parenteral infection did not significantly affect the odds of being consistently viraemic (AOR 1.14, P = 0.703) and there was no significant difference in the odds of having consistently elevated ALT levels and mode of acquisition (AOR 0.83, P = 0.748). The proportion of children with 2 or more markers of HCV infection did not differ significantly by mode of acquisition (χ(2) 1.13, P = 0.288). This analysis does not support substantial differences between vertically and parenterally infected groups, but there are specific mechanisms identified requiring further investigation. Given the continued parenteral infection of children worldwide, it is vital that knowledge of disease progression in this group is accurate and that the differences in comparison with vertically infected children are clarified to inform more accurate and individualized clinical management.

Increase in invasive Streptococcus pyogenes and Streptococcus pneumoniae infections in England, December 2010 to January 2011

Increases in invasive Streptococcus pyogenes and S. pneumoniae above the seasonally expected levels are currently being seen in England. Preliminary analyses suggest that the high level of influenza activity seen this winter may be contributing to an increased risk of concurrent invasive bacterial and influenza infections in children and young adults.

Prevalence of chronic viral hepatitis in people of south Asian ethnicity living in England: the prevalence cannot necessarily be predicted from the prevalence in the country of origin

The prevalence of hepatitis B and hepatitis C in immigrant communities is unknown. Immigrants from south Asia are common in England and elsewhere, and the burden of viral hepatitis in these communities is unknown. We aimed to determine the prevalence of viral hepatitis in immigrants from south Asia living in England, and we therefore undertook a community-based testing project in such people at five sites in England. A total of 4998 people attending community centres were screened for viral hepatitis using oral fluid testing. The overall prevalence of anti-hepatitis C virus (HCV) in people of south Asian origin was 1.6% but varied by country of birth being 0.4%, 0.2%, 0.6% and 2.7% in people of this ethnic group born in the UK, India, Bangladesh and Pakistan, respectively. The prevalence of hepatitis B surface antigen was 1.2%-0.2%, 0.1%, 1.5% and 1.8% in people of this ethnic group born in the UK, India, Bangladesh and Pakistan, respectively. Analysis of risk factors for HCV infection shows that people from the Pakistani Punjab and those who have immigrated recently are at increased risk of infection. Our study suggests that migrants from Pakistan are at highest risk of viral hepatitis, with those from India at low risk. As prevalence varies both by country and region of origin and over time, the prevalence in migrant communities living in western countries cannot be easily predicted from studies in the country of origin.

The rationale for the use of measles post-exposure prophylaxis in pregnant women: a review

A review of published literature was undertaken to investigate the maternal and fetal effects of measles infection in pregnancy and to inform the need for post-exposure prophylaxis. There is no evidence to support an association between measles in pregnancy and congenital defects. However, the need for effective post-exposure protection is supported by studies suggesting a high risk of severe maternal morbidity, fetal loss and prematurity. Measles in late pregnancy can also lead to perinatal infection in the infant, which may be associated with a high mortality and the risk of subacute sclerosing panencephalitis. UK guidance recommends using human normal immunoglobulin for susceptible pregnant women exposed to measles. Although there is no direct evidence that this will reduce the complications of measles in pregnancy, it may attenuate disease and therefore reduce the rate of complications. Measures to identify women likely to be susceptible include assessment of age, vaccination history, and/or antibody testing.

Protecting infants against measles in England and Wales: a review

OBJECTIVE

To establish the most appropriate age ranges for the use of human normal immunoglobulin and MMR vaccine as postexposure prophylaxis.

DESIGN

Review of literature and of laboratory confirmed measles cases.

SETTING

England and Wales and countries with a similar measles epidemiological profile.

PATIENTS

Women of childbearing age and infants.

MAIN OUTCOME MEASURES

The risk of measles, maternally derived measles antibody levels and the response to measles containing vaccines in infants.

RESULTS

By 4 to 5 months of age, only 28-45% of infants born to women from highly vaccinated populations have protective levels of measles antibody. In the postvaccine era, between 74% and 80% of infants vaccinated between 6 and 9 months respond to vaccine, and around 67% have clinical protection from measles vaccination.

CONCLUSION

This study suggests that many infants being born in the UK will become susceptible to measles before 6 months and will be able to respond to vaccine between 6 and 9 months of age. It is proposed that current guidance is changed to recommend passive immunisation with human normal immunoglobulin for most infants exposed to measles below 6 months of age. For infants aged 6 months or over exposed to measles, vaccination with MMR may be given.
