Erector Spinae Plane Block and Paravertebral Block for Breast Surgery: A Retrospective Propensity-Matched Noninferiority Trial.

Purpose: Thoracic paravertebral block (TPVB) is an established analgesic technique for breast surgery although it is technically challenging. Erector spinae plane block (ESPB) requires less technical expertise and may be an alternative to TPVB. However, whether ESPB has similar analgesic effects to TPVB for breast surgery is still inconclusive.

[Development of oral function and eating habits of infants living in a city area of Japan: in relation to the results of dental health examinations of infants aged 14 months at public health centers].

Objective: The aim of this study was to investigate the relationships between eruption of deciduous teeth and eating habits determined by health examinations of infants.

Methods: We verified eruption of deciduous teeth based on observations of 455 fourteen-month-old infants at health examinations in a ward of Tokyo, and performed a questionnaire survey involving their mothers regarding the hardness of infants' meals and their eating habits. We examined 420 infants excluding 17 whose births were 'pre-term delivery (born at or before 36 weeks)' and 18 whose questionnaire had excessive omissions.
