Changes in life-style after liver transplantation

Sixty-five pediatric patients who received liver transplants between May 1981 and May 1984 were observed for as many as 5 years and examined for changes in life-style. Children were less frequently hospitalized, spent less time hospitalized, required fewer medications, and generally had excellent liver and renal function after hepatic transplantation as compared with their pretransplantation status. Most children were in age-appropriate and standard school classes or were only 1 year behind. Cognitive abilities remained unchanged. Children improved in gross motor function and patients' behavior significantly improved according to parents' perceptions. Enuresis was more prevalent, however, than in the population of children who had not received liver transplants. Parental divorce rates were no greater than those reported for other families with chronically ill children. Overall, objective changes in life-style as well as parents' perceptions of behavior of children appear to be improved after liver transplantation

CONSENSUS CONFERENCE REPORT ON LIVER* TRANSPLANTATION.

Liver transplantation has been developed to the point of a service operation, the exploitation of which depends upon the establishment of multiple regional centers. The increased use of this procedure will permit the delivery of optimum health care to victims of end stage liver disease

Choosing a pediatric recipient for orthotopic liver transplantation

Between March 3, 1981, and June 1, 1984, 216 children were evaluated for orthotopic liver transplantation. Of the 216 patients, 117 (55%) had recelved at least one liver transplant by June 1, 1985. Fifty-five (25%) died before transplantation. The 117 patients who received transplants were grouped according to severity of disease and degree of general decompensation at the time of transplantation. The severity of a patient's medical condition with the possible exception of deep hepatic coma, did not predict outcome following orthotopic liver transplantation. Seventy variables were assessed at the time of the evaluation. Twenty-three of the 70 variables were found to have prognostic significance with regard to death from progressive liver disease before transplantation. These 23 variables were Incorporated into a multivariate model to provide a means of determining the relative risk of death among pediatric patients with end-stage liver disease. This information may allow more informed selection of candidates awaiting liver transplantation. © 1987 The C. V. Mosby Company

Pregnancy after liver transplantation under tacrolimus

Background. The maternal and fetal risk of pregnancy after organ transplantation under tacrolimus has not been reported. This was prospectively studied in 27 pregnancies by 21 female liver recipients who were treated with tacrolimus before and throughout gestation. Method. Twenty- seven babies were born between October 1990 and April 1996. In 15 cases, samples were obtained at or after delivery and stored (-40°C) for comparison of tacrolimus concentration in the maternal blood with different combinations of cord and infant venous blood, breast milk, or a section of the placenta. Results. The 21 mothers had surprisingly few serious complications of pregnancy and no mortality. Two infants with 23 and 24 weeks gestation died shortly after birth. The mean birth weight of the other 25 was 2638±781 g after a gestational period of 36.0±3.3 weeks. Mean birth weight percentile for gestational age was 50.2±26.2 (median 40). On the day of delivery, the mean tacrolimus concentrations (ng/ml) were 4.3 in placenta versus 1.5, 0.7, and 0.5 in maternal, cord, and child plasma, and 0.6 in the first breast milk specimens. The infants had a 36% incidence of transient perinatal hyperkalemia (K+>7.0 meq/L) and a mild reversible renal impairment, which were thought to reflect in part maternal homeostasis. One newborn had unilateral polycystic renal disease (the only anomaly). All 25 babies have had satisfactory postnatal growth and development with a current mean weight percentile of 62±37 (median 80). Conclusions. Pregnancy by postliver transplant mothers under tacrolimus was possible with a surprisingly low incidence of the hypertension, preeclampsia, and other maternal complications historically associated with such gestations. As in previous experience with other immunosuppressive regimens, preterm deliveries were common. However, prenatal growth for gestational age and postnatal infant growth for post- partum age were normal

Liver and kidney transplantation in children receiving cyclosporin A and steroids

The new immunosuppressive agent, cyclosporin A, was used with low doses of steroids to treat eight patients undergoing hepatic transplantation and three patients undergoing cadaveric renal transplantation. Seven of the eight liver recipients are well, including one who was given two livers. The three kidney recipients, who had developed cytotoxic antibodies after previously rejecting grafts with conventional immunosuppressive therapy, have had good results despite conditions which usually preclude attempts at transplantation. The ability to control rejection effectively and safely without chronic high-dose steroid therapy may make the described therapeutic regimen valuable for pediatric recipients of whole organs. © 1982 The C.

Entrepreneurial growth and ownership under market socialism in China: a longitudinal case study of small business growth

How firms grow is still a mystery and a definitive explanation remains elusive. This is especially the case for emerging economies, where the development of research into business growth has been notably slow whilst emerging business ventures are developing at hyper speed. Since most empirical studies have focused on the quantitative differences in growth across firms, this paper adopts a longitudinal case study approach to explore the qualitative differences in terms of how various types of firm achieve their growth outcomes in the organisational development process over a prolonged period of time. Through a theoretical lens which focuses on growth process approaches, this study not only demonstrates that entrepreneurial processes take different forms and dimensions in different contexts, but it also provides insights into the interactions of various organisational factors underpinning the strategies and changes that lead to contrasting growth outcomes. Case study findings assert that the ownership factor is a key contingent factor that shapes management structure and resources which, in turn, affect particular entrepreneurial outcomes. Furthermore, a combination of leadership style and the approach to knowledge management also play critical roles in the learning process which, tends to determine the strategy choice of either high or low value added product strategy. The findings of this research are that small firms with a low value product strategy can improve their survival chances and growth through the vertical broadening of a product portfolio in synchrony with increasing production and technology advancement. The case study companies show a tendency to reinforce their industry position by adopting contrasting choices for growth. The paper addresses the challenges and managerial implications for Western company managers in different growth contexts

Planning for precarity? Experiencing the carceral continuum of imprisonment and reentry

Drawing on qualitative interviews with formerly imprisoned people in Canada, we show that most prisoners experience reentry into communities with little to no pre-release planning, and must rely upon their own resourcefulness to navigate fragmented social services and often informal supports. In this respect, our research findings contrast with U.S. punishment and society scholarship that highlights a complex shadow carceral state that extends the reach of incarceration into communities. Our participants expressed a critical analysis of the failure of the prison to address the needs of prisoners for release planning and supports in the community. Our findings concur with other empirical studies that demonstrate the enduring effects of the continuum of carceral violence witnessed and experienced by prisoners after release. Thus, reentry must be understood in relation to the conditions of confinement and the experience of incarceration itself. We conclude that punishment and society scholarship needs to attend to a nuanced understanding of prisoner reentry and connect reentry studies to a wider critique of the prison industrial complex, offering more empirical evidence of the failure of prisons

Diagnosis of childhood cancer.

Childhood cancer is uncommon but remains the leading cause of disease-related death in children. Symptoms are often vague or insidious; they may suggest a more common alternative diagnosis, and they are quite different from those associated with adult malignancy. The skilled office practitioner must consider cancer as a diagnosis when symptoms/signs persist or when multiple symptoms point toward a possible diagnosis of malignancy. Early diagnosis is critical, as survival rates have increased dramatically over the past decades. Prolonged delay in diagnosis is common, especially for brain tumors and certain lymphomas (Hodgkin disease). When one encounters symptoms suspicious for a childhood malignancy, it is imperative that the child be referred to a pediatric cancer center. These centers possess not only the ability to further evaluate and manage children with malignancy, but also are able to provide support for patients and their families. This evaluation may include further imaging, but often involves obtaining tissue for histologic review. This will require appropriate tumor or bone marrow biopsy, preferably before the start of treatment. Depending upon the type of suspected malignancy, direct tumor biopsy can be facilitated by imaging-guided biopsy (ultrasound, CT, or MRI), which spares the patient additional surgery. This optimally is performed by a skilled team: hematologist/oncologist, surgeon, radiologist, and pathologist. Best results depend upon early referral by the thoughtful practitioner

A gene encoding a liver-specific ABC transporter is mutated in progressive familial intrahepatic cholestasis.

The progressive familial intrahepatic cholestases (PFIC) are a group of inherited disorders with severe cholestatic liver disease from early infancy. A subgroup characterized by normal serum cholesterol and gamma-glutamyltranspeptidase (gammaGT) levels is genetically heterogeneous with loci on chromosomes 2q (PFIC2) and 18q. The phenotype of the PFIC2-linked group is consistent with defective bile acid transport at the hepatocyte canalicular membrane. The PFIC2 gene has now been identified by mutations in a positional candidate, BSEP, which encodes a liver-specific ATP-binding cassette (ABC) transporter, sister of p-glycoprotein (SPGP). The product of the orthologous rat gene has been shown to be an effective bile acid transporter in vitro. These data provide evidence that SPGP is the human bile salt export pump (BSEP)
