ABSTRACT

OBJECTIVE: To assess the association between ketonuria and hyperemesis gravidarum (HG) disease severity. STUDY DESIGN: We included pregnant women hospitalised for HG who participated in the Maternal and Offspring outcomes after Treatment of HyperEmesis by Refeeding (MOTHER) trial and women who were eligible, chose not to be randomised and agreed to participate in the observational cohort. Between October 2013 and March 2016, in 19 hospitals in the Netherlands, women hospitalised for HG were approached for study participation. The presence of ketonuria was not required for study entry. Ketonuria was measured at hospital admission with a dipstick, which distinguishes 5 categories: negative and 1+ through 4 + . The outcome measures were multiple measures of HG disease severity at different time points: 1) At hospital admission (study entry): severity of nausea and vomiting, quality of life and weight change compared to pre-pregnancy weight, 2) One week after hospital admission: severity of nausea and vomiting, quality of life and weight change compared to admission, 3) Duration of index hospital admission and readmission for HG at any time point RESULTS: 215 women where included. Ketonuria was not associated with severity of nausea and vomiting, quality of life or weight loss at hospital admission, nor was the degree of ketonuria at admission associated with any of the outcomes 1 week after hospital admission. The degree of ketonuria was also not associated with the number of readmissions. However, women with a higher degree of ketonuria had a statistically significant longer duration of hospital stay (per 1+ ketonuria, difference: 0.27 days, 95 % CI: 0.05 to 0.48). CONCLUSIONS: There was no association between the degree of ketonuria at admission and severity of symptoms, quality of life, maternal weight loss, or number of readmissions, suggesting that ketonuria provides no information about disease severity or disease course. Despite this, women with a higher degree of ketonuria at admission were hospitalised for longer. This could suggest that health care professionals base length of hospital stay on the degree of ketonuria. Based on the lack of association between ketonuria and disease severity, we suggest it has no additional value in the clinical management of HG.

ABSTRACT

OBJECTIVE: To evaluate the effect of successful external cephalic version on the incidence of developmental dysplasia of the hip (DDH) requiring treatment in singleton breech presentation at term. DESIGN: Observational cohort study. SETTING: Three large teaching hospitals in the Netherlands. POPULATION: Women with a singleton breech presentation of 34 weeks of gestation or more, who underwent an external cephalic version attempt. METHODS: We made a comparison of the incidence of DDH between children born in breech presentation and children born in cephalic presentation after a successful external cephalic version. MAIN OUTCOME MEASURE: The incidence of DDH requiring either conservative treatment, with a harness, or surgical treatment. RESULTS: A total of 498 newborns were included in the study, of which 40 (8%) were diagnosed with DDH and 35 required treatment. Multivariate analysis showed that female gender (OR 2.79, 95% CI 1.23-6.35) and successful external cephalic version (OR 0.29, 95% CI 0.09-0.95) were independently associated with DDH. CONCLUSIONS: A successful external cephalic version is associated with a lower incidence of DDH, although a high percentage of children born after a successful external cephalic version still appear to have DDH. A larger cohort study is needed to establish the definite nature of this relationship. Until then, we recommend the same screening policy for infants born in cephalic position after a successful external cephalic version as for infants born in breech position.

ABSTRACT

Early detection and subsequent treatment of developmental dysplasia of the hip (DDH) is thought to improve its prognosis. Frequently reported risk factors for DDH are a positive family history of DDH, female sex and breech presentation, but there is not a lot of systematic knowledge about DDH risk factors. We performed a systematic review and meta-analysis of the available evidence on DDH risk factors. We searched Medline, EMBASE and The Cochrane Library from conception up until October 2011 for primary articles on the subject. All studies reporting on potential risk factors for DDH that allowed construction of a two-by-two table were selected. Language restrictions were not applied. Two reviewers independently selected studies, extracted data and assessed study quality. The association between risk factors and DDH was expressed as a common odds ratio (OR) with a 95% confidence interval (CI). We identified 30 relevant studies reporting on 1,494,387 children; 26 studies were cohort studies and four studies used a case-control design. The risk of DDH was strongly increased in case of breech delivery (OR 5.7, 95% CI 4.4-7.4), female sex (OR 3.8, 95% CI 3.0-4.6) a positive family history of DDH (OR 4.8, 95% CI 2.8-8.2) and clicking hips at clinical examination (OR 8.6, 95% CI 4.5-16.6). This meta-analysis shows that infants born in breech presentation, female infants, infants with a positive family history and clicking hips at clinical examination have an increased risk for DDH. This knowledge can be helpful in the development of screening programs for DDH.

ABSTRACT

OBJECTIVE: Analysis of the effects of population-based determinants (maternal age, parity, multiple pregnancy and ethnicity) and of professional and organisational factors (conservative management in case of early preterm birth, the policy on prenatal screening and the Dutch obstetric-care system in general) on perinatal mortality. DESIGN: Population-based prospective cohort study. METHOD: In a regional cohort (Zaanstreek) of 8031 pregnancies in the period 1990-1994 data were prospectively collected in an electronic database by deliverers of primary and secondary care. Analysis focussed on the effect on perinatal mortality of maternal age, parity, multiple pregnancy, ethnicity and professional and organisational factors (the policy in case of early preterm birth, the policy on prenatal screening and the Dutch obstetric-care system in general). Perinatal mortality was defined as mortality from a gestational age of 22 weeks until 28 days post partum. RESULTS: The perinatal mortality in the Zaanstreek was 12.6/1000. Increasing the gestational age to 28 weeks decreased the perinatal mortality by 29%. The perinatal mortality in this cohort was significantly affected by parity, multiple pregnancy and maternal age (relative risk: 2.8), but not by ethnicity if corrected for the previous factors. Conservative management in case of early preterm birth and a restrictive screening policy for lethal birth defects were associated with an increase in perinatal mortality. In 31 of 92 singleton pregnancies followed by perinatal mortality, a relationship to substandard care was established. In 7 cases this relationship was probable and in 1 case the midwife was responsible. CONCLUSION: Given the magnitude of their effects, both independently and via interaction, stratification for maternal age, parity, multiple pregnancy and ethnicity must precede any interpretation and comparison of perinatal mortality rates. Although clinical policy played a modest role, a negative role of the organisation of obstetric care was unlikely in this cohort. A definitive judgement as to the quality of perinatal care would require extension of the evaluation to at least the entire first year of life in connection with the morbidity. The most favourable effects can be expected from stimulatory measures directed at lowering the age at first pregnancy.

ABSTRACT

A retrospective analysis of the management of intestinal obstruction in 31 patients with advanced ovarian carcinoma is described. Between 1981 and 1992 31 patients developed intestinal obstruction after their initial treatment. Nineteen patients underwent surgery, while the remaining 12 were treated conservatively. Careful evaluation with contrast studies of both the small intestine and colon is recommended to improve the prediction of site(s) of obstruction, and may reduce the number of unsuccessful operative procedures. Fifteen of the surgically treated patients survived for a period of 60 days or more. The majority, 13, were discharged to their homes after an average hospital stay of 24 days. Major postoperative complications occurred in three of the 19 patients. There was no surgical-related mortality. Two patients died within 30 days postoperatively (urosepsis and advanced tumor). While the median survival in the 19 surgical treated patients was 109 days (range 15-775), the conservatively treated 12 patients survived for a mean of 37 days (range 6-260). Surgical management of intestinal obstruction in selected cases is feasible and improves quality of life substantially.
