6% in the postnatal group. CONCLUSIONS The CSA in the fetal group was larger than that in the postnatal group, which may explain the decrease in the prevalence of hydrocephalus in the fetal group.Pediatric Index of Mortality (PIM) 2 score is used in pediatric intensive care unit (PICU) to predict the patients' risk of death. The performance of this model has never been assessed in Switzerland. The aim of this study was to evaluate the performance of the PIM2 score in the whole cohort and in pre-specified diagnostic subgroups of patients admitted to PICUs in Switzerland. All children younger than 16 years admitted to any PICU in Switzerland between January 1, 2012 and December 31, 2017 were included in the study. A total of 22,382 patients were analyzed. Observed mortality was 2%, whereas mortality predicted by PIM2 was 4.2% (SMR = 0.47, 95% CI, 0.42-0.52). Calibration was also poor across the deciles of mortality risks (p  less then  0.001). The AUC-ROC for the entire cohort was 0.88 (95% CI, 0.87-0.90). Calibration varied significantly according to primary diagnosis.Conclusion The performance of the PIM 2 score in a cohort of Swiss patients is poor with adequate discrimination and poor calibration. The PIM 2 score tends to under predict the number of deaths among septic patients and in patients admitted after a cardiorespiratory arrest.What is Known•PIM2 score is a widely used mortality prediction model in PICU.•PIM2 performance among uncommon but clinically relevant diagnostic subgroups of patients is unknown.•The performance of PIM2 score has never been assessed in Switzerland.What is New•The performance of the PIM 2 score in a cohort of Swiss patients is poor with adequate discrimination and poor calibration.•Calibration varies significantly according to primary diagnosis. The PIM 2 score under predict the number of deaths among septic patients and in patients admitted after a cardiorespiratory arrest.This post hoc Poisson regression analysis investigated the relationship between mean volume voided and incontinence episodes/24 h after fixed frequency adjustment in children with overactive bladder from the LION study, a phase 3, double-blind, randomised, placebo-controlled, sequential, dose-titration solifenacin trial. Patients were aged 5- less then  12 years with ≥ 4 episodes of daytime incontinence during a 7-day pre-baseline diary period. The dependent variable was the mean number of incontinence episodes/24 h at the end of study. Explanatory variables included treatment, mean number of incontinence episodes/24 h at baseline, and change from baseline to end of study in mean volume voided. Statistical significance and goodness of fit were analysed using the Pearson's chi-square test. A negative estimate was found between the dependent variable 'incontinence' and both mean volume voided and daytime maximum volume voided/micturition (an increase in mean volume voided or daytime maximum volume voided/mictur24 h.INTRODUCTION Laparoscopic resection of the hepatic caudate lobe (LRCL) requires a high level of expertise due to its challenging anatomical area. Only case reports, case series, and single-center cohort studies have been published. The aim of this study was to assess the safety and feasibility of this laparoscopic procedure. METHODS A multicenter retrospective cohort study including all patients who underwent LRCL in 4 high-volume hepatobiliary units between January 2000 and May 2018 was performed. Perioperative, postoperative, and survival outcomes were assessed. Postoperative morbidity was stratified according to the Clavien-Dindo classification with severe complications defined by grade III or more. The Kaplan-Meier method was used for survival analysis. RESULTS A total of 32 patients were included, including 22 (68.8%) with colorectal liver metastasis (CRLM), one (3.1%) with cholangiocarcinoma, four (12.5%) with other malignancies, and five (15.6%) with symptomatic benign lesions. Simultaneous colorectal and/or additional liver resection was performed in 20 (62.5%) patients. The median (IQR) operative time was 155 (121-280) minutes, blood loss was 100 (50-275) ml, conversion rate was 9.4% (n = 3), severe complications were observed in 2 patients (6.3%), and median (range) length of hospital stay was 3 [1-39] days. No 90-day postoperative mortality was noticed. The median (IQR) follow-up for the CRLM group was 14 [10-23] months. Five-year overall survival rate was 82% in this subgroup. Small interinstitutional differences were observed without major impact on surgical outcomes. CONCLUSION LRCL is safe and feasible when performed in high-volume centers. Profound anatomical knowledge, advanced laparoscopic skills, and mastering intraoperative ultrasound are essential. No major interinstitutional differences were ascertained.Contracaecum rudolphii (s. l.) is a complex of sibling species of anisakid nematodes having the fish-eating birds belonging to the Family Phalacrocoracidae as final hosts. The great cormorant Phalacrocorax carbo sinensis is parasitized by C. rudolphii A and C. rudolphii B. Adults and L4 specimens of C. rudolphii (s. l.) (N = 3282) were collected in cormorants from brackish and freshwater ecosystems of Central Italy. Third-stage larvae of Contracaecum (N = 882) were obtained from the fish species Dicentrarchus labrax, Anguilla anguilla, Aphanius fasciatus, Atherina boyeri, Leuciscus cephalus, Barbus barbus, and Carassius carassius captured in the same geographical areas of cormorants' standings. Contracaecum rudolphii A and C. rudolphii B were identified by a multilocus genetic approach allozymes, sequences analysis of the mtDNA cox2, and ITS region of rDNA gene loci. Differential distribution of the two parasite species was observed in different aquatic environments. Contracaecum rudolphii B outnumbered C. rudolphii A in wintering cormorants from freshwater ecosystems; the opposite trend was found in cormorants from brackish water. Analogously, C. rudolphii A larvae were more prevalent in brackish water fish, while C. rudolphii B larvae were found infecting only freshwater fish. The findings seem to confirm that C. rudolphii A and C. this website rudolphii B would have a life-cycle adapted to brackish and freshwater environments, respectively. A differential feeding behavior of wintering cormorants, the ecology of the infected fish species, and abiotic factors related to early stages of the parasites are supposed to maintain the distinctiveness of the two parasite species' life cycles in the two different aquatic ecosystems.
