    BACKGROUND: It has been hypothesized that prematurity and adjunctive neonatal care is 'a priori' a risk for disturbances of palatal and orofacial development which increases the need for later orthodontic or orthognathic treatment. As results on late consequences of prematurity are consistently contradictory, the necessity exists for a fundamental analysis of existing methodologies, confounding factors, and outcomes of studies on palatal development in preterm and low birthweight infants. METHOD: A search of the literature was conducted based on Cochrane search strategies including sources in English, German, and French. Original data were recalculated from studies which primarily dealt with both preterm and term infants. The extracted data, especially those from non-English paper sources, were provided unfiltered in tables for comparison (Parts 1 and 2). RESULTS: Morphology assessment of the infant palate is subject to non-standardized visual and metrical measurements. Most methodologies are inadequate for measuring a three-dimensional shape. Several confounding factors were identified as causes contributing to disturbances of palatal and orofacial development. CONCLUSION: Taking into account the abovementioned shortcomings, the following conclusions may be drawn for practitioners and prospective investigators of clinical studies. 1) The lack of uniformity in the anatomical nomenclature of the infant's palate underlines the need for a uniform definition. 2) Metrically, non-intubated preterm infants do not exhibit different palatal width or height compared to matched term infants up to the corrected age of three months. Beyond that age, no data on the subject are currently available. 3) Oral intubation does not invariably alter palatal morphology of preterm and low birthweight infants. 4) The findings on palatal grooving, height, and asymmetry as a consequence of orotracheal intubation up to the age of 11 years are inconsistent. 5) Metrically, the palates of orally intubated infants remain narrower posteriorly, beginning at the second deciduous molar, until the age of 11 years. Beyond that age, no data on the subject are currently available. 6) There is a definite need for further, especially metrical, longitudinal and controlled trials on palatal morphology of preterm and low birthweight infants with reliable measuring techniques. 7) None of the raised confounding factors for developmental disturbances may be excluded until evident results are presented. Thus, early orthodontic and logopedic control of formerly premature infants is recommended up to the late mixed dentition stage

    © 2019 John Wiley & Sons Ltd Objective: To examine risk of emergency hospital admission and survival following adjuvant chemotherapy for early breast cancer. Methods: Linked data from New South Wales population-based and clinical cancer registries (2008–2012), hospital admissions, official death records and pharmaceutical benefit claims. Women aged ≄18 years receiving adjuvant chemotherapy for early-stage operable breast cancer in NSW public hospitals were included. Odds ratios (OR) for emergency hospitalisation within 6 months following chemotherapy initiation were estimated using logistic regression and survival using Kaplan–Meier and Cox proportional hazards methods. Results: A total of 3,950 women were included and 30.6% were hospitalised. The most common principal diagnosis at admission was neutropenia (30.8%). Women receiving docetaxel/carboplatin/trastuzumab (TCH) and docetaxel/cyclophosphamide (TC) were the most frequently hospitalised. After adjustment for demographic and clinical factors, the increased risk of hospitalisation for TCH and TC remained compared with doxorubicin/cyclophosphamide 3-weekly (OR 1.71, 95% confidence interval [CI] 1.24–2.37 and OR 1.47, 95% CI 1.17–1.85 respectively). Five-year overall survival was similar for women who were (92.2%, 95% CI 90.7–93.8) and were not hospitalised (93.1%, 95% CI 92.1–94.1). Conclusion: Emergency hospitalisations following chemotherapy for early breast cancer were relatively common, especially following docetaxel-containing protocols. Further examination of reasons for admission is needed to inform actions to improve patient safety
