Breastmilk intake and growth in infants from two to ten months

Longitudinal measurements of breastmilk intake in 48 Cambridge infants showed that intake reached a peak of 824 g/24 h in boys and 741 g/24 h in girls in the third and fourth months, respectively. Regression analysis demonstrated that, in the early months, the infants' weight accounted for a major part of the variance in breastmilk intake. Infants in non-manual social classes received more breastmilk and started solids later than those in manual groups. In the early months weight gain showed a relative increase compared to growth standards, but later infancy was characterized by a progressive deceleration in weight and length gain. Adiposity, as measured by triceps skinfold thickness differed most markedly from growth charts and was only equivalent to the tenth standard centile at all ages. The lower skinfold thickness measurements are considered to be more appropriate to breastfed infants in general.     

Multiple coronary artery-left ventricular fistulae: clinical, angiographic, and pathologic findings

Multiple fistulae between all 3 major coronary arteries and the left ventricle were found at cardiac catheterization in a 69-year-old woman presenting with typical angina. Subsequent necropsy showed abnormal intramyocardial vessels communicating with the left ventricular lumen. This is the first report to document clinical, angiographic, and pathologic findings in this anomaly.     

When in vitro fertilization fails: a prospective view.

New reproductive technologies such as in vitro fertilization (IVF) offer much hope to infertile couples, yet the odds for success are not high. In this study we examine the experiences of a cohort of women undergoing IVF or a related technology at three points in time: before technological intervention, approximately one month after the first failed cycle, and six months later. We consider the women's expectations and experiences and discuss implications of the findings for social work practice.     

Myocardial reperfusion injury: the critical challenge.

Oxygen-free radical production and reperfusion injury are complex mechanisms. New and improved methods for maximizing the benefits of reperfusion while minimizing reperfusion injury are on the horizon in the 1990s. Critical care nurses play a crucial role in the assessment, planning, and intervention of patients experiencing the deleterious effects of free radicals and reperfusion injury. Thus, a sound knowledge base in the pathophysiology of reperfusion injury, the detrimental effects of free radicals, and the potential benefits of free-radical scavengers is essential.     

The impact of lower urinary tract symptoms on general health status and on the use of prostatectomy

Our objective was to determine the extent to which lower urinary tract symptoms affect the general health status of men and contribute to the decision to undergo surgery. A cross-sectional population survey using postal questionnaires was conducted in the North West Thames health region, followed by a prospective cohort study of men undergoing prostatectomy (North West Thames and Oxford regions). The subjects in the first survey were 221 men aged 55 and over with previously reported mild, moderate or severe urinary symptoms; subjects in the second study were 388 men undergoing prostatectomy. Main outcome measures were selfreported symptom severity, bothersomeness and general health status (Nottingham Health Profilie, Part 1). The response rate among eligible responders in the population survey was 85.7%. Increasing symptom severity was associated with worsening NHP scores for energy, emotional reactions, sleep and physical mobility (p<0.01). Increasing bother-someness of symptoms was associated with emotional reactions, sleep and pain (p<0.05). Men undergoing surgery reported worse health status than men in the population with the same severity of symptoms as regards emotional reactions, energy and pain. For a given level of symptom severity, the impact of those symptoms on aspects of a man's general health status may be the determinant of seeking and undergoing surgery. Greater understanding of the factors that affect a man's response to his symptoms is needed in interpreting the decision to seek and accept treatment.     

Harvey Cushing's postoperative sketches of pediatric brain tumors

Harvey Cushing was a man of many talents. Not only was he a premier surgeon and scientist, but a prolific author and artist as well. In this paper, we present two postoperative sketches of pediatric brain tumors drawn by Dr. Cushing. These sketches are representative of drawings which accompany many of his operative notes at the Peter Bent Brigham Hospital. About 25% of Cushing's surgical sketches depict operations performed on children. The most commonly drawn childhood tumors were craniopharyngiomas and gliomas of the brain stem and cerebellum. These drawings reveal how Cushing maintained detailed records of his surgical experience. It is clearly evident from these records that Dr. Cushing gained substantial experience in the treatment of pediatric brain tumors.     

Composite tissue (limb) allografts in rats. III. Development of donor-host lymphoid chimeras in long-term survivors

Eight LEW rat recipients possessing long-term-surviving (206-701 days) LBN vascularized hind limb allografts (CTAs) were tested for donor-host lymphoid chimerism. The recipients received various cyclosporine (CsA) treatment protocols in order to induce indefinite CTA acceptance. Histological examination of long-term-surviving CTAs demonstrated normal-appearing bone marrow in the donor limb. Lymphocytes isolated from host hemopoietic tissues (peripheral blood and/or spleen) by ficoll-hypaque density gradient centrifugation were tested against LEW-anti-BN antisera. Comparisons were made to standard curves employing various known concentrations of LBN and LEW cell combinations. The level of lymphocyte agglutination (dependent variable) showed a significant (P less than 0.025-0.005) linear relationship to the concentration of LBN donor cells (independent variable) present. Lymphocyte suspensions isolated from long-term CTA host peripheral blood and/or spleen showed a mean of 19.7% (+/- 9.7-95% confidence interval) donor LBN mononuclear cells present. Thus, it appeared that lymphoid cells originated from, and/or were released from LBN donor bone marrow into the circulation, resulting in chimeric repopulation of hemopoietic tissues. The presence of donor immunocytes in these limb allograft recipients may have been beneficial, and thus could have helped contribute to the long-term CTA survival observed.     

Weight changes in a couples program: negative association of marital adjustment

This study investigated the difference in weight changes of subjects who rated their marriages as more adjusted vs subjects who rated their marriages as less adjusted. Twenty-six moderately obese subjects were assigned to one of two groups based on their initial scores on the Locke-Wallace Marital Adjustment Scale (MAS). The 10 subjects in the "moderately unhappy" group (MAS less than or equal to 99) lost significantly more weight than the 16 subjects in the "relatively happy" group (MAS greater than or equal to 100) at the end of the one-year treatment program (29.9 lb vs 20.4 lb) and at 3-month follow-up (27.7 lb vs 17.8 lb). Significantly more subjects in the unhappy group also reached ideal weight than subjects in the happy group (50% vs 7.7%). Subjects' initial MAS scores were significantly and negatively correlated with weight changes at post-treatment and follow-up; partners' MAS scores at the end of treatment were also significantly and negatively correlated to subjects' weight losses at post-treatment. None of the couples was initially maritally distressed but one couple met this criterion (MAS less than or equal to 85) by the end of treatment and follow-up. It was concluded that marital counseling is not a prerequisite for weight counseling, couples' marital adjustment does not improve as the subject loses weight and a moderate level of marital dissatisfaction does not seem to be an insurmountable barrier to successful weight loss and may be an advantage for some individuals.
