Young infants' visual fixation patterns in addition and subtraction tasks support an object tracking account.

Investigating infants' numerical ability is crucial to identifying the developmental origins of numeracy. Wynn (1992) claimed that 5-month-old infants understand addition and subtraction as indicated by longer looking at outcomes that violate numerical operations (i.e.

Fine needle aspiration cytology of seromas of the breast from irradiated lumpectomy sites.

Objective: To study the cytologic features of cells in breast aspirates of seromas in women who had undergone irradiation at lumpectomy sites.

Study Design: Cytologic material from 38 females with an age range of 39-72 years who had undergone aspiration of seromas were retrieved to determine tumor recurrence or other atypia. The material was obtained using the conventional method of needle aspiration with a 22-gauge needle and 10-mL syringe, maintaining negative pressure.

Aspiration cytodiagnosis of the breast with abundant acellular calcific material indicative of soft tissue calcinosis (a study of 3 cases).

Calcific deposits in soft tissue are rare and may clinically resemble a tumour. It seems feasible, therefore, to investigate them by the non-invasive technique of fine needle aspiration cytology (FNAC). In this study three cases with extensive accumulation of acellular calcific material in the breast are described in which FNAC was indicative of soft tissue calcinosis.
