Increased spinal c-Fos expression with noxious and non-noxious peripheral stimulation after severe spinal contusion.

The effects of severe contusive spinal cord injury (SCI), at thoracic level 8 (T8), on lumbar c-Fos expression in the spinal cord was investigated. As hypothesized, chronic SCI has a significant effect on expression of c-Fos in the dorsal spinal sensory areas with noxious and innocuous peripheral stimulation of the sciatic nerve. This alteration to stimulation effects was measured using counts of c-Fos immunoreactive cells in the dorsal horn of the L5 lumbar spinal cord in injured animals at 90 days post-injury and in uninjured controls. The number of c-Fos immunoreactive cells increased in SCI rats only after noxious peripheral stimulation (electrical and chemical) suggesting a general increase in excitability in spinal pathways (central sensitization) associated with chronic SCI. These altered responses may represent a functional anatomical reorganization of spinal cord circuitry leading to increased dorsal horn c-Fos expression as a response to severe chronic contusive damage to the spinal cord sensory pathways.

[Maternal perception of the quality of care given to their children during hospitalization].

In order to evaluate the perception of mothers on the care given to their hospitalized children, a survey was specially designed and carried out with 100 mothers on the day of their child's discharge. Hospital care was rated excellent or good by a 96%, regular or bad by 4% of surveyed mothers. Most (74%) mothers saw at least one member of the caring team acting affectionately with their children; only 2% complained that her child was reprimanded or punished. Lack of equipment or human resources and comfort facilities were frequently perceived by mothers but quality of care was generally considered to be satisfactory. This kind of studies is probably useful to improve community's health services.

[Growth, acceptance, and tolerance with a new milk formula].

The purpose of this investigation was to evaluate the effect of a modified cow's milk formula on growth, tolerance and acceptability, which was studied in 2,097 infants selected from those controlled in primary health centers at Santiago, Chile: 1,119 were fed a modified cow's milk formula (LPM), while an unmodified powdered cow's milk (LP) was given to 978 controls of the same age and conditions, as well as solid foods after 4 months of age. Both experimental and control groups were followed along a 4 months period for records of anthropometric data, morbidity, acceptability and tolerance for LP and LPM. We did not find significant differences in growth (values ranging 95 to 100% of NCHS standards W/A or H/A). A slightly higher energy intake and lower protein intake was observed with LPM. Gastrointestinal symptoms were infrequently seen and of similar frequency and character in both 0 to 4 month old groups (4.3% with LPM vs. 5.3% with LP at first control). These gastrointestinal signs were more frequently recorded under LPM than with LP in the 8 to 12 months old group only at first control (colics 8% vs. 4% p < 0.01 and abnormal stools 9.4% vs. 5.5% p < 0.01). Acute acceptability expressed as percentage withdrawal from study was not significantly lower with LPM than LP (5 to 15% vs. 2% N.S.). The proposed modified formula seems to be a good alternative to powdered cow's milk for infants.
