Neuroblastoma in an adult

Neuroblastoma is extremely rare in adults. Advances in classification and therapy have been recently made by an analysis of pediatric tumors. We present the case of a 39-year-old man who had Stage 1 neuroblastoma with unfavorable histologic features that was treated with surgery only. Neuroblastoma should be considered as a diagnosis for adult patients with a suprarenal mass and, if confirmed, neuroblastoma in adults should be classified and treated according to pediatric guidelines.     

Successful percutaneous coil occlusion of a large pulmonary arteriovenous malformation

Pulmonary arteriovenous malformation is one of the rarest congenital anomalies of cardiovascular system. We present a case of 30-year-old female with a large pulmonary arteriovenous malformation (PAVM) arising from the right lower pulmonary artery and draining to the left atrium. She underwent successful embolization using three detachable Cook coils.     

Epilepsy surgery outcome among US veterans

We retrospectively studied the outcome of anterior temporal lobectomy (ATL) among a population of veterans and evaluated outcome related to comorbidities. Veterans who underwent ATL between 1990 and 2001 at the Veterans Administration Hospital in Madison, Wisconsin, were included. Data related to postoperative seizure outcome, quality of life outcome, and employment outcome were collected. Factors associated with favorable outcome and outcome related to comorbidities were evaluated. Twenty-seven patients were entered into the study. The mean age at onset of seizures was 25 years (+/-10.2). History of a non-substance abuse psychiatric diagnosis, and substance abuse was present in 26% (7/27) and 30% (9/27), respectively, prior to surgery. While 66.6% (18/27) had a good outcome (Engel's Class I), no difference in the frequency of good outcome was seen among the patients with a history of substance abuse, other psychiatric diagnosis (71%), or no psychiatric diagnosis (67%). There was a significant correlation between seizure outcome and quality of life score (r(s)=0.67, p<0.001) and postoperative employment gains (r(s)=0.48, p=0.01). Outcomes among veterans that underwent ATL can be satisfactory even in the context of the late mean age of epilepsy onset and the psychiatric diagnoses that were present in this sample.     

Visceral artery aneurysms—follow-up of 23 patients with 31 aneurysms after surgical or interventional therapy

Purpose  

Visceral artery aneurysms (VAA) are rare forms of vascular pathology, with an incidence of 0.1% to 0.2% in routine autopsies [1–4]. They frequently present as a life-threatening, often fatal, emergency, if associated with rupture and intra- or retroperitoneal bleeding. The clinical symptoms, natural history, and mortality of VAAs vary depending on the vessels involved. The mortality rates range from 8.5% up to 25% and, in pregnant women, up to 75% [1, 4, 6, 7]. A retrospective analysis of all VAAs diagnosed at our institution from 1991 to 2006 was performed. The presentation, management, and outcome of therapy was evaluated for each patient.     

Banff Schema for Grading Pancreas Allograft Rejection: Working Proposal by a Multi-Disciplinary International Consensus Panel

Accurate diagnosis and grading of rejection and other pathological processes are of paramount importance to guide therapeutic interventions in patients with pancreas allograft dysfunction. A multi-disciplinary panel of pathologists, surgeons and nephrologists was convened for the purpose of developing a consensus document delineating the histopathological features for diagnosis and grading of rejection in pancreas transplant biopsies. Based on the available published data and the collective experience, criteria for the diagnosis of acute cell-mediated allograft rejection (ACMR) were established. Three severity grades (I/mild, II/moderate and III/severe) were defined based on lesions known to be more or less responsive to treatment and associated with better- or worse-graft outcomes, respectively. The features of chronic rejection/graft sclerosis were reassessed, and three histological stages were established. Tentative criteria for the diagnosis of antibody-mediated rejection were also characterized, in anticipation of future studies that ought to provide more information on this process. Criteria for needle core biopsy adequacy and guidelines for pathology reporting were also defined.
The availability of a simple, reproducible, clinically relevant and internationally accepted schema for grading rejection should improve the level of diagnostic accuracy and facilitate communication between all parties involved in the care of pancreas transplant recipients.     

The Dijon Physical Activity Score: reproducibility and correlation with exercise testing in healthy elderly subjects]

PURPOSE: To validate a French physical activity score for current use in healthy elderly people. PATIENTS AND METHODS: A brief questionnaire was developed for healthy elderly subjects older than 72 years. Questions asked about self-assessed physical fitness (1), daily activity (2), leisure and sport activity (5) and rest time (1). Correlations were searched between the score and several parameters of physical fitness: maximal exercise stress test (peak VO(2)), six-minute walk test, 200-meter long walk test, timed up an go test. RESULTS: A total of 57 subjects were studied (mean age, 77.6 +/-3.6 years; 28 females and 29 males). The mean time to complete the questionnaire was 3.96 minutes. Reproducibility was 0.606, as determined by Spearman's coefficient. Correlations were found between the physical activity score and peak VO(2) (0.302, P <0.05) and peak power (0.257, P <0.10). CONCLUSIONS: This easily obtained physical activity score provides a new way to assess physical activity in active elderly subjects. The physical score correlated in part with maximal ability but must be validated in several diseases.
