Predictors of a successful primary bladder closure in cloacal exstrophy: A multivariable analysis

Purpose

To investigate the factors affecting primary bladder closure in cloacal exstrophy (CE). A successful primary closure is important for optimizing reconstructive outcomes, and it is a critical first-step in the reconstruction of CE. The authors' hypothesize that a smaller diastasis and use of an osteotomy are independent predictors of a successful closure.

Dual Vulnerability of Being Both a Teen and an Immigrant Parent: Illustrations from an Italian Context

Italy has experienced a recent surge in immigration, which has led to an increase in the country’s birth rate. Many immigrant mothers are adolescent parents. 30 adolescent mothers (17 recent immigrants and 13 adolescents of Italian descent) completed measures of adolescent self-development and motherhood, perceived availability and satisfaction with social support, and emotional and behavioral characteristic of their children. Findings suggest that immigrant teen mothers show more difficulties related to parenting than do Italian born teen mothers. In particular, immigrant teen mothers report lower levels of social support satisfaction and availability, higher levels of parent–child dysfunction, and experience motherhood and child behavior as more problematic. The findings highlight and confirm the need for well-designed, specific supportive services for adolescent immigrant mothers.     

Etanercept (Enbrel) in patients with rheumatoid arthritis with recent onset versus established disease: improvement in disability

OBJECTIVE: To compare etanercept-induced improvement in disability of patients with recent onset of rheumatoid arthritis (RA) to that of patients with established RA. METHODS: Health Assessment Questionnaire (HAQ) scores were collected over 3 years in 2 groups of patients with RA who were treated with etanercept. The first group consisted of 207 patients with recent onset RA (mean duration of 1 year) who had not previously received methotrexate, and the second group consisted of 464 patients with established RA (mean duration of 12 years) who had failed one or more disease-modifying antirheumatic drugs. RESULTS: Baseline demographics and disease characteristics were similar in the 2 groups, except for HAQ scores and C-reactive protein levels, which were higher in the established RA group. Patients in both groups showed rapid and sustained clinical responses with etanercept therapy, but patients with recent onset RA showed significantly greater improvement in HAQ scores compared with patients with established RA. The difference in magnitude of HAQ score improvement between groups was observed as early as week 2 after initiation of etanercept and persisted throughout the 3-year time frame. At year 3, significantly more patients with recent onset RA had a HAQ score of zero (26%) versus those with established RA (14%, p = 0.0095). CONCLUSION: Although etanercept therapy significantly improved disability scores in both groups, patients with recent onset of RA showed greater benefit in HAQ scores than patients with established RA. These results support prompt treatment of RA at an early stage of disease to minimize patient disability.

Effect of prosthetic aortic valve design on the Doppler-catheter gradient correlation: an in vitro study of normal St. Jude, Medtronic-Hall, Starr-Edwards and Hancock valves.

To evaluate the normal range of Doppler-derived velocities and gradients, their relation to direct flow measurements and the importance of prosthetic valve design on the relation between Doppler and catheter-derived gradients, five sizes of normal St. Jude bileaflet, Medtronic-Hall tilting disc, Starr-Edwards caged ball and Hancock bioprosthetic aortic valves were studied with use of a pulsatile flow model. A strong linear correlation between peak velocity and peak flow, and mean velocity and mean flow, was found in all four valve types (r = 0.96 to 0.99). In small St. Jude and Hancock valves, Doppler velocities and corresponding gradients increased dramatically with increasing flow, resulting in velocities and gradients as high as 4.7 m/s and 89 mm Hg, respectively. The ratio of velocity across the valve to velocity in front of the valve (velocity ratio) was independent of flow in all St. Jude, Medtronic-Hall, Starr-Edwards and Hancock valves when the two lowest flow rates were excluded for Hancock valves. Although Doppler peak and mean gradients correlated well with catheter peak and mean gradients in all four valve types, the actual agreement between the two techniques was acceptable only in Hancock and Medtronic-Hall valves. For St. Jude and Starr-Edwards valves, Doppler gradients significantly and consistently exceeded catheter gradients with differences as great as 44 mm Hg. Thus, Doppler velocities and gradients across normal prosthetic heart valves are highly flow dependent. However, the velocity ratio is independent of flow.(ABSTRACT TRUNCATED AT 250 WORDS)     

Cyclosporine as prophylaxis for graft-versus-host disease: a randomized study in patients undergoing marrow transplantation for acute nonlymphoblastic leukemia

Seventy-five patients, 13 to 49 years of age, with acute nonlymphoblastic leukemia in first remission were treated with cyclophosphamide, fractionated total body irradiation, and marrow transplantation from an HLA-identical sibling and randomized to receive either cyclosporine (CSP) (n = 36) or methotrexate (MTX) (n = 39) as prophylaxis for graft-v-host disease (GVHD). All patients engrafted, and 22 who were given CSP and 21 who were given MTX, are alive at 20 to 47 (median, 35) months (P = .5). Engraftment as assessed by granulocyte recovery (P less than .0005) and platelet transfusion requirement (P = .01) was faster in patients on CSP. Twelve patients (33%) on CSP and 22 (56%) on MTX developed acute GVHD of grades II through IV (P = .07) and 15 of 30 on CSP and 14 of 32 on MTX that were at risk developed chronic GVHD. The most frequent causes of death were interstitial pneumonitis and marrow relapse of leukemia, which occurred with similar frequency in both groups. Beneficial effects observed in patients on CSP included less severe mucositis and shorter duration of hospitalization; adverse effects included renal function impairment and hypertension. These data confirm that CSP is a useful immunosuppressant in patients undergoing marrow transplantation but fail to show a significant improvement in survival as compared with the standard regimen of MTX.
