A new approach to massive blood transfusion during pediatric liver resection

Morbidity and death during liver resection in children are due to hemorrhage and the consequences of massive transfusion. To overcome these problems, a new rapid method of blood transfusion was used in four children (8 to 35 months, 8.6 to 13 kg) undergoing extensive hepatic resection for tumor (tumor weight, 440 to 1625 gm). The rapid infusion device consisted of a roller pump and a bubble oxygenator-warmer circuit primed with washed packed red cells resuspended in fresh-frozen plasma and calcium-free balanced salt solution (Plasmalyte). The infusate was warmed, oxygenated, and buffered before it was administered. An average of 5130 ml per patient of this reconstituted blood was infused at an average rate of 122 +/- 45 ml/min, with peak infusion rates sometimes as great as 1 L/min. Cardiac output, pulmonary artery wedge pressure, body temperature, urine output, blood gases, blood chemistries, and coagulation factors remained unchanged during and after these massive transfusions. Blood transfusion at rapid rates required during pediatric liver resection can be accomplished safely if the storage lesion of the bank blood is previously corrected.     

The role of radiation therapy in Hodgkin disease: experience and controversy. The 54th annual Janeway Lecture: 1989.

BACKGROUND. Beginning in 1970, a series of patients with Hodgkin disease were treated at the University of Minnesota, after staging laparotomy, with radiation therapy (RT) for Stage I, II, and IIIA Hodgkin disease. This report is an analysis of the results of the treatment and of treatment modifications. METHODS. From 1970 to 1974, all patients were treated with standard RT. In 1975, an analysis of these patients indicated that patients with large mediastinal mass (LMM) and patients with Stage IIIA spleen-positive (IIIAS+) disease had a higher recurrence rates than patients without these factors. Subsequently, a schema of radical radiation therapy (RRT) was devised, which included low-dose lung RT for patients with LMM and low-dose liver RT for patients with IIIAS+ disease. RESULTS. Analysis of the results of the two treatments indicates that the use of low-dose lung RT in patients with LMM and low-dose liver RT in patients with IIIAS+ Hodgkin disease produced survival and recurrence-free survival results equivalent to those achieved by use of combined modality treatment (CMT) or chemotherapy (CT) alone. CONCLUSIONS. The use of RT with whole lung and liver irradiation for patients with LMM and IIIAS+ Hodgkin disease, respectively, produces results that are equivalent to those of CMT or CT alone with the advantage of a decreased incidence of second malignant neoplasms. In addition, patients who do not respond to initial RT have a greater chance of being saved with chemotherapy than do patients initially treated with CMT of being saved with RT. The authors suggest that radical RT is the treatment of choice for patients with LMM and/or IIIAS+ Hodgkin disease.     

Parents' knowledge of neonatal screening and response to false-positive cystic fibrosis testing.

Neonatal screening for cystic fibrosis (CF) has become feasible through analyzing dried blood specimens for immunoreactive trypsinogen (IRT), but the benefits and risks of such a screening program remain to be delineated. This study, a survey of the parents of 104 Wisconsin infants with false-positive IRT tests, showed parents had knowledge deficits about neonatal screening in general, misconceptions about test results, and high levels of anxiety. Parenting behaviors were reportedly unchanged during the usual 3-day waiting period between the news of the abnormal screening test and the diagnostic sweat test. Most, but not all, parents were relieved by negative sweat test results subsequent to the abnormal IRT test. Factors associated with continued parental concern included having less than a high school education and/or having an infant with low Apgar scores. Additionally, those contacted by telephone were more likely to have misinformation and lingering concerns about the presence of CF in their child.     

Impact of beliefs about HIV treatment and peer condom norms on risky sexual behavior among gay and bisexual men

The association between perceptions about condom use among one's peers, beliefs about new HIV treatments, and HIV sexual risk behavior was examined in a large urban sample ( N = 454) of gay and bisexual men in the Southeast. Results partially confirmed the hypothesis that men who endorsed new HIV treatment beliefs would report lower norms for condom use and higher HIV sexual risk behaviors than men who failed to endorse HIV treatment beliefs but with casual, and not main, partners. Moreover, results confirmed the hypothesis that the association between HIV treatment beliefs and unprotected sex would be partially mediated by peer condom norms. Results suggest social interventions are needed to promote condom norms in the social context of new HIV treatments. © 2006 Wiley Periodicals, Inc.     

Developing an integrated public health information system for Missouri.

The Missouri Department of Health realized it had a problem with 67 different information systems that ran on different platforms and could not communicate with one another. A new, integrated information system, the Missouri Health Strategic Architectures and Information Cooperative (MOHSAIC) is being developed based on information engineering (IE). This article describes IE, the process of developing MOHSAIC, and some key lessons learned in developing the system. Some of the lessons learned include the importance of executive sponsorship, tension between efficiency and program accountability, importance of confidentiality, and difficulties of funding an integrated system. The article stresses how integrated information systems will be important for the viability of public health under health care reform.     

Incontinence and troublesome behaviors predict institutionalization in dementia.

Factors predicting the early institutionalization of demented patients were studied in 143 outpatients using univariate and multivariate life-table methods. Four types of factors were evaluated for prognostic value: severity of functional impairment, behavioral disorders, individual patient characteristics, and type of caregiver. After follow-up of 19 +/- 12 months, 51 patients had been institutionalized. Increased global severity of dementia, the presence of troublesome and disruptive behaviors, and incontinence increased the likelihood of institutionalization. The best predictors of institutionalization were paranoia, aggressive behavior, and incontinence. Neither individual patient characteristics (age, education, and gender) nor caregiver relationship to the patient (male spouse, female spouse, and male or female child) influenced institutionalization. Since troublesome behavioral disorders are potentially treatable aspects of dementia leading to institutionalization, their management should be a major focus of therapy in dementia.
