Community-acquired pneumonia (CAP) is of predominant interest in analysing the burden of airway diseases. No population-based incidence data for children in Germany exist. In retrospective cohort studies from 1999 to 2001, parents of an entire age-class (28,000-30,000) of 5-to 7-year-old children at school entry medical examination (S1) in a complete federal state (Schleswig-Holstein, population 2.77 million) were interviewed by the Children and Adolescent Service of the Public Health Service. CAP was defined as pneumonia diagnosed by a physician at the time it occurred. The proportion of children investigated (participation rate) was 82.0-86.1%. The CAP-positive rate was 6.7-7.4%, 6.9-8.2% of whom had recurrent CAP. The mean age at first CAP was 36.4-39.4 months (median 42 months). This resulted in a population-based incidence for the age groups 0-1 year and 0-5 years (under 5) of 1,664-1,932 and 1,369-1,690 per 100,000, respectively; 93.7-95.9% received antibiotics. For each percent of CAP, 458 days (1999), 312 days (2000) and 319 days (2001) of at least one parent's work were lost, respectively. Conclusions: Despite a relatively weak case definition, the population-based incidence of CAP before school entry was the same as recently reported form California and about 30-50% of that reported 20 to 40 years ago in the USA and Finland.Keywords Cohort AE Pneumonia AE School entry AE Incidence AE Public health serviceAbbreviations ARI acute respiratory tract infection AE CAP community-acquired pneumonia AE CAS children and adolescent service AE LRI lower respiratory tract infections AE PHO public health office (Gesundheitsamt) Subjects and methodsIn three retrospective cohort studies from 1999 to 2001, parents of children aged 5-7 years were interviewed by the Children and Eur J Pediatr (2003) 162: 309-316

SUMMARYA multivariate time-series regression model was developed in order to describe the 2005-2008 age-specific time-course of varicella sentinel surveillance data following the introduction of a varicella childhood vaccination programme in Germany. This ecological approach allows the assessment of vaccine effectiveness under field conditions by relating vaccine coverage in cohorts of 24-month-old children to the mean number of cases per reporting unit in the sentinel network. For the 1-2 years age group, which is directly affected by the vaccination programme, a one-dose vaccine effectiveness of 83 . 2% (95 % CI 80 . 2-85 . 7) was estimated which corresponds to previous approaches assessing varicella vaccine effectiveness in the field in the USA.

General anaesthesia for obstetric surgery has distinct characteristics that may contribute towards a higher risk of accidental awareness during general anaesthesia. The primary aim of this study was to investigate the incidence, experience and psychological implications of unintended conscious awareness during general anaesthesia in obstetric patients. From May 2017 to August 2018, 3115 consenting patients receiving general anaesthesia for obstetric surgery in 72 hospitals in England were recruited to the study. Patients received three repetitions of standardised questioning over 30 days, with responses indicating memories during general anaesthesia that were verified using interviews and record interrogation. A total of 12 patients had certain/ probable or possible awareness, an incidence of 1 in 256 (95%CI 149-500) for all obstetric surgery. The incidence was 1 in 212 (95%CI 122-417) for caesarean section surgery. Distressing experiences were reported by seven (58.3%) patients, paralysis by five (41.7%) and paralysis with pain by two (16.7%). Accidental awareness occurred during induction and emergence in nine (75%) of the patients who reported awareness. Factors associated with accidental awareness during general anaesthesia were: high BMI (25-30 kg.m -2 ); low BMI (<18.5 kg.m -2 ); out-of-hours surgery; and use of ketamine or thiopental for induction. Standardised psychological impact scores at 30 days were significantly higher in awareness patients (median (IQR [range]) 15 (2.7-52.0 [2-56]) than in patients without awareness 3 (1-9 [0-64]), p = 0.010. Four patients had a provisional diagnosis of post-traumatic stress disorder. We conclude that direct postoperative questioning reveals high rates of accidental awareness during general anaesthesia for obstetric surgery, which has implications for anaesthetic practice, consent and follow-up.
