Acute Renal Allograft Rejection Following Pegylated IFN-α Treatment for Chronic HCV in a Repeat Allograft Recipient on Hemodialysis: A Case Report

Interferon alpha (IFN-alpha) can be effective therapy for patients with chronic kidney disease who have chronic hepatitis C (HCV). However, acute allograft rejection has been reported in association with IFN-alpha following kidney transplantation, and therefore IFN therapy is recommended prior to, rather than after, kidney transplantation whenever feasible. The special case of repeat allograft recipients who contract HCV after the first transplantation presents special difficulties. This report features the case of a repeat allograft recipient who presented with neutropenic fevers after 5 months of pegylated IFN-alpha therapy, initiated 6 months following the functional loss of his third graft and the reinitiation of hemodialysis (HD). Physical exam, radiographic and laboratory findings led to allograft nephrectomy. The pathologic findings supported a diagnosis of acute-on-chronic rejection. This represents a rare case of IFN-alpha induced rejection following allograft failure and return to HD in a repeat allograft recipient. It also calls attention to the need for a high index of suspicion for the development of allograft rejection, which may require allograft nephrectomy even after allograft 'failure'.     

Computed tomographic scanning of the foot and ankle

Computed tomography (CT) has become the gold standard for cross-sectional imaging in the foot and ankle. The literature is full of studies and case reports where CT has definately elucidated osseous and soft-tissue pathology.     

Service needs of youths released from a state psychiatric facility as perceived by service providers and families

The following article reports on the results of service needs assessments of a cohort of youths released from a state psychiatric facility as perceived by service providers and families/caregivers. Families as well as service providers consistently agreed on three service areas of high need—psychotherapy for the child, family therapy and parent skill training. However, families perceived a need for a number of other services that are not traditionally provided by the mental health system such as after school recreation activities and self-help and support groups for the child. The discrepancies between service providers and families' perceptions of assessed needs may lead to families dropping out of service due to the unresponsiveness of the services in meeting their perceived needs. Steps that service providers need to take to be more responsive to the needs of families are discussed.This study was funded by a grant from the Office of Program Evaluation and Research, Ohio Department of Mental Health.     

Right adrenal gland hemorrhage as a complication of liver transplantation: CT appearance

Three patients presented with right adrenal gland hemorrhage as a complication of orthotopic liver transplantation. The CT appearance, possible pathophysiologic mechanism, and significance of this finding are discussed.     

Patulous rectum extension into the ischiorectal fossa: CT findings.

Protrusion of the rectum with egress into the ischiorectal fossa was present on computed tomography (CT) in three elderly women. CT demonstration of such rectal redundancy in elderly women will avoid unnecessary bowel damage in the case of misguided clinical assessment of rectal pathology.     

Reduction by delayed hypothermia of cerebral infarction following middle cerebral artery occlusion in the rat: a time-course study.

The effect of hypothermia on neuronal injury following permanent middle cerebral artery (MCA) occlusion in the rat was examined. Moderate hypothermia (body temperature 24 degrees C) was induced before MCA occlusion (0-minute delay group) in six rats, at 30 minutes in eight rats, and at 1 (seven rats), 2 (seven rats), and 3 (nine rats) hours after occlusion. The rats were kept at a 24 degrees C body temperature for 1 hour, then allowed to rewarm over 90 minutes. The animals were sacrificed 24 hours after MCA occlusion, and infarction was visualized by staining of coronal sections with 2,3,5-triphenyltetrazolium chloride. Infarct volumes were compared to matched normothermic control rats (body temperature 36 degrees C). Additional groups of 0-minute delay hypothermic (10 rats) and control animals (nine rats) were sacrificed 72 hours after MCA occlusion to examine the effects of prolonged survival. A significant reduction in the percentage of infarcted right hemisphere was seen in the animals sacrificed after 24 hours with 0-minute, 30-minute, and 1-hour delays in inducing hypothermia (mean +/- standard error of the mean: 2.2% +/- 0.7%, 4.4% +/- 0.9%, and 3.6% +/- 1.1%, respectively) as compared to normothermic control rats (10.8% +/- 1.5%, p less than 0.01 by Student's t-test). In the 2- and 3-hour delay groups, the percentage of infarcted right hemisphere was 17.1% +/- 2.4% and 12.0% +/- 2.7%, respectively, and no decrease in infarct volume was observed. The 0-minute delay hypothermia group sacrificed after 72 hours also displayed a significant reduction in right hemisphere infarct compared to their respective controls (4.8% vs. 11.7%, p less than 0.05). These findings indicate that, in the setting of permanent MCA occlusion, hypothermia markedly decreases brain injury even when its induction is delayed for up to 1 hour after the onset of ischemia. Ischemic damage does not appear to be merely retarded but permanently averted.     

High-risk endometrial cancer in young indigent women

OBJECTIVE: The aim of this study was to evaluate a different prevalence and clinical pattern of high-risk endometrial cancer in an indigent population of young women. METHODS: Charts of 71 consecutive patients, treated for endometrial adenocarcinoma during a 6-year period, were reviewed. The patients were divided into two groups contingent upon age--(i) those who were below 40 years and (ii) those who were over 40. Based on histological type, grade, and stage, both groups were subdivided into a low, intermediate, or high-risk cancer category. RESULTS: Of the 13 (18.3%) patients in the younger age group, five patients (38.4%) had high-risk endometrial cancer, compared to only eight patients (13.8%) in the older age group. CONCLUSION: In contradiction to previous reports, our results show that a higher proportion of young indigent women diagnosed with endometrial cancer have a high-risk cancer. Delay in diagnosis can explain only some of the discrepancies in the special clinical pattern of endometrial cancer among this population. Other possible explanations include nutritional differences, genetic susceptibility, immunological status, and high-risk behavior. More epidemiological studies are needed for complete understanding of the unfavorable outcome of endometrial cancer in these young women.     

An External Aortic Root Device for Decreasing Aortic Regurgitation: In Vitro and In Vivo Animal Studies

Objectives: The purpose of this study was to determine if a device placed externally around the aortic root decreases regurgitant flow in acute aortic regurgitation. Background: Aortic regurgitant flow is dependent on central aortic pressure and the aortic root and leaflet geometry. It may be possible to decrease aortic regurgitant severity by reducing aortic root size or dimension changes. Methods: Aortic regurgitation was created in eight calf heart specimens suspended in a continuous flow system. Retrograde and antegrade aortic flow and distending aortic pressure were measured at baseline and after placement of an external aortic device at the level of the aortic annulus. In two additional specimens, the incompetent aortic valve was visualized fiberoptically before and after placement of the external device. Acute aortic regurgitation was created surgically in four live calves by excising a portion of the aortic leaflets. Antegrade and retrograde flow, left ventricular pressure, and central aortic pressure were measured at baseline, after creation of aortic regurgitation, and after placement of the external device. Results: In the in vitro calf specimens, regurgitant flow decreased from 46.9 cc/sec to 15.1 cc/sec (66.0%± 21.8% decrease) after placement of the external device (p < 0.001). The regurgitant orifice area decreased from 0.13 ± 0.04 cm² to 0.04 ± 0.02 cm² after device placement (p < 0.001). Antegrade flow was reduced to a smaller extent (20.0%± 19.2% decrease) by the device (p < 0.05). Placement of the device around the aorta resulted in improved coaptation of the leaflets with a marked reduction in defect size by endoscopic visualization. Use of the external aortic device was associated with improvement in aortic regurgitant severity in three of four calves with surgically created aortic regurgitation. Concluslons: In these preliminary studies, acute experimental aortic regurgitant severity is decreased by the use of an external aortic device, probably due to reduction in aortic annular dimension changes and improved aortic leaflet apposition. Further studies are needed to determine the effectiveness of this device in chronic aortic regurgitation. (J Card Surg 1994;9:304–313)     

A new syndrome with features of the Smith-Lemli-Opitz and Meckel-Gruber syndromes in a sibship with cerebellar defects

The Smith-Lemli-Opitz syndrome (SLOS) and the Meckel syndrome (MS) have been regarded as separate autosomal recessive entities. Recently, overlap of these two syndromes has been discussed. A sibship containing a probable new syndrome with features reminiscent of the SLOS and the MS is presented. The literature is reviewed with regard to the frequency of various malformations in these syndromes. Clinical manifestations and cerebellar abnormalities in these sibs are similar to those described in the Joubert syndrome (JS). These three cases may represent a new syndrome with features in common with SLOS, MS, and JS resulting from the same mutant gene, which exhibits considerable pleiotropy.     

Community service utilization by youths hospitalized in a state psychiatric facility

A majority of a cohort of 62 children and adolescents who had been hospitalized in a state psychiatric facility was found to have received less restrictive services such as outpatient mental health services prior to their index admission. Also, a number had been involved with the juvenile justice system and almost two-thirds had been placed out-of-home. Ninety percent had at least one prior psychiatric hospitalization. Just over half of the cohort received case management and individual counseling post release. About a third received family counseling, and a few received other types of services. At least a third were rehospitalized within a year of release. Although 90% of the cohort received some type of service post release, a higher proportion of non service receivers were rehospitalized than service receivers. Even those who received services had a high rate of rehospitalization. These findings raise questions as to the appropriateness of service provision during and following hospitalization.This study was funded by a grant from the Office of Program Evaluation and Research, Ohio Department of Mental Health.
