Severe Pulmonary Arteriopathy in a Neonate with Congenital Rubella Syndrome and Patent Ductus Arteriosus

Neonates with congenital rubella syndrome (CRS) are known to have associated congenital cardiac malformations. Patent ductusarteriosus (PDA) is one the most common cardiac anomalies associated with CRS. PDA refractory to medical management andassociated with ventilatory dependence is considered for surgical ligation. However, the management of PDA can be challenging in thepresence of underlying lung disease or pulmonary vascular disease. Outcomes after closure in neonates are dependent upon age,weight, nutritional status, pre-operative pulmonary arterial hypertension and presence of chronic lung disease. We present a neonatewith CRS who required surgical PDA closure. The neonate developed severe pulmonary arterial hypertension which led to fatal outcome.The clinical course is corroborated with histo-pathological changes observed on the autopsy of this neonate.

Meningococcal disease outbreak related to the World Scout Jamboree in Japan, 2015

Problem: Six invasive meningococcal disease cases occurred among Scottish and Swedish nationals associated with the World Scout Jamboree (WSJ), an international mass gathering, held in Japan. The index case developed symptoms while returning home. The strains from all six cases were identical and seldom seen in Japan. Context: Over 33 000 participants from 155 countries attended WSJ. At the Jamboree site, participants of the North of Scotland’s and Sweden’s units camped within the same subcamp and kept the same schedule of events. No information was available about the Swedish and Scottish cases’ close personal contact history. Action: Health Protection Scotland investigated Scottish cases, conducted active case finding, provided chemoprophylaxis, vaccinated close contacts and advised Scottish WSJ participants and contacts to seek medical care if they developed symptoms. The Public Health Agency of Sweden recommended chemoprophylaxis to all participants in Sweden. In Japan, the Ministry of Health, Labour and Welfare (MHLW) requested the Scout Association of Japan advise all participants to seek medical attention if they developed symptoms. MHLW shared information about the event with local authorities, medical associations, and the Ministry of Education, Culture, Sports, Science and Technology. Outcome: No additional case related to WSJ has been reported. This outbreak highlighted the risk for international spread of invasive meningococcal disease at international mass gatherings. Discussion: Assessing risk, educating participants, enhancing surveillance and sharing timely information among related countries are significant for prevention and response against invasive meningococcal disease outbreaks at mass gatherings.

The burden of congenital rubella syndrome in the Philippines: results from a retrospective assessment

Introduction: In line with the regional aim of eliminating rubella and congenital rubella syndrome (CRS), phased introduction of rubella-containing vaccines (RCV) in the Philippines’ routine immunization programme began in 2010. We estimated the burden of CRS in the country before widespread nationwide programmatic RCV use. Methods: We performed a retrospective chart review in four tertiary hospitals. Children born between 1 January 2009 and 31 December 2014 and identified as possible CRS cases based on the presence of one or more potential manifestations of CRS documented in hospital or clinic charts were reviewed. Cases that met the clinical case definition of CRS were classified as either confirmed (with laboratory confirmation) or probable (without laboratory confirmation). Cases that did not fulfil the criteria for either confirmed or probable CRS were excluded from the analysis. Results: We identified 18 confirmed and 201 probable cases in this review. Depending on the hospital, the estimated incidence of CRS ranged from 30 to 233 cases per 100 000 live births. The estimated national burden of CRS was 20 to 31 cases per 100 000 annually. Discussion: This is the first attempt to assess the national CRS burden using in-country hospital data in the Philippines. Prospective surveillance for CRS and further strengthening of the ongoing measles-rubella surveillance are necessary to establish accurate estimates of the burden of CRS and the impact of programmatic RCV use in the future.
