In a private pediatric practice, 94 infants who were breast-feeding were followed for the first 2 months of life in order to define the frequency of cessation of breast-feeding and to identify factors that would predict mothers and infants at risk for early cessation. At 8 weeks, 30% of the mothers had stopped nursing. Factors associated with cessation were: maternal lack of confidence in breast-feeding (P < .001); anticipated duration of nursing less than 6 months (P = .002); ratings by the nursery staff of infant's excessive crying (P = .007), infant's demanding personality (P = .007), trouble with féeding (P = .001), and future trouble with feeding (P = .004). Together, these factors predicted 77% of the mothers who terminated breast-feeding. Supplementing with formula before the 2-week office visit also led to termination of breast-feeding by 8 weeks (P = .006). This decision was frequently made without medical advice. Nearly 64% (14/22) of the mothers who added formula within the first 2 weeks did so without contacting the pediatric practice.

Hexachlorophene (HCP), a chlorinated phenolic hydrocarbon with bacteriostatic properties against Staphylococcus, is used in a number of topical products. Absorption through normal and damaged human skin has been appreciated and neurologic changes have been described in experimental animals, but instances of human toxicity have been reported infrequently. A 10-year-old boy who sustained a 25% burn did well initially but died in the second week of convalescence with hyperthermia, lower-extremity weakness, and cerebral edema. His treatment had included frequent applications of HCP. Analysis of post-mortem tissue revealed the presence of toxic levels of HCP in the blood (2.2µg/gm) and brain (2.2µg/gm), with storage in skin (25µg/gm). liver (4.4µg/gm), and fat (6.0µg/gm). This case suggests that topical applications of HCP in man may result in an extensive absorption with fat storage and may cause fatal encephalopathy.
