Recurrent constrictive pericarditis associated with seropositive rheumatoid arthritis: A case report

IntroductionConstrictive pericarditis is an uncommon disease characterized by impaired diastolic filling of the ventricles, encased in a fibrotic pericardium resulting from an inflammatory process.Rheumatoid arthritis is a rare cause of constrictive pericarditis, usually due to a concomitant acute or chronic serositis.Presentation of caseThis paper presents a unique case of recurrent constrictive pericarditis associated with seropositive rheumatoid arthritis, requiring pericardiectomy and complicated three years later by recurrent fibrosis, demanding a second pericardiectomy.DiscussionDefining this entity as recurrent constrictive “pericarditis” might be a mistake, given that a total pericardiectomy was performed in first instance.No risk factors for recurrent fibrosis have been identified in the current medical literature, apart from partial pericardiectomy. We cannot demonstrate exclusively that rheumatoid arthritis is a risk factor for recurrent pericardial/epicardial fibrosis due to the rare nature of the disease.ConclusionFurther large scale studies are necessary to identify the risk factors for recurrence.

Epigenetic Role of Histone 3 Lysine Methyltransferase and Demethylase in Regulating Apoptosis Predicting the Recurrence of Atypical Meningioma

Alteration of apoptosis is related with progression and recurrence of atypical meningiomas (AMs). However, no comprehensive study has been conducted regarding histone modification regulating apoptosis in AMs. This study aimed to determine the prognostic values of certain apoptosis-associated factors, and examine the role of histone modification on apoptosis in AMs. The medical records of 67 patients with AMs, as diagnosed during recent 13 yr, were reviewed retrospectively. Immunohistochemical staining was performed on archived paraffin-embedded tissues for pro-apoptotic factors (CASP3, IGFBP, TRAIL-R1, BAX, and XAF1), anti-apoptotic factors (survivin, ERK, RAF1, MDM2, and BCL2), and the histone modifying enzymes (MLL2, RIZ, EZH1, NSD2, KDM5c, JMJD2a, UTX, and JMJD5). Twenty-six (38.8%) patients recurred during the follow-up period (mean duration 47.7 months). In terms of time-to-recurrence (TTR), overexpression of CASP3, TRAIL-R1, and BAX had a longer TTR than low expression, and overexpression of survivin, MDM2, and BCL2 had a shorter TTR than low expression (P<0.05). Additionally, overexpression of MLL2, UTX, and JMJ5 had shorter TTRs than low expression, and overexpression of KDM5c had a longer TTR than low expression. However, in the multi-variate analysis of predicting factors for recurrence, low expression of CASP3 (P<0.001), and BAX (P<0.001), and overexpression of survivin (P=0.007), and MDM2 (P=0.037) were associated with recurrence independently, but any enzymes modifying histone were not associated with recurrence. Conclusively, this study suggests certain apoptosis-associated factors should be associated with recurrence of AMs, which may be regulated epigenetically by histone modifying enzymes.

Orthotopic liver transplantation as a rescue operation for recurrent hepatocellular carcinoma after partial hepatectomy

AIM： To compare post-orthotopic liver transplantation （OLT） survival between patients with recurrent hepatocellular carcinoma （HCC） after partial hepatectomy and those who received de novo OLT for HCC and to assess the risk factors associated with post-OLT mortality. METHODS： From July 2003 to August 2005, 77 consecutive HCC patients underwent OLT, including 15 patients with recurrent HCC after partial hepatectomy for tumor resection （the rescue OLT group） and 62 patients with de novo OLT for HCC （the de novo OLT group）. Thirty-three demographic, clinical, histological, laboratory, intra-operative and post-operative variables were analyzed. Survival was calculated by the Kaplan- Meier method. Univariable and multivariable analyses were also performed. RESULTS： The median age of the patients was 49.0 years. The median follow-up was 20 mo. Three patients （20.0%） in the rescue OLT group and 15 patients （24.2%） in the de novo OLT group died during the follow-up period （P = 0.73）. The 30-day mortality of OLT was 6.7% for the rescue OLT group vs 1.6% for the de novo OLT group （P = 0.27）. Cox proportional hazards model showed that pre-OLT hyperbilirubinemia, the requirement of post-OLT transfusion, the size of the tumor, and family history of HCC were significantly associated with a higher hazard for mortality. CONCLUSION： There are no significant differences in survival/mortality rates between OLT as de novo therapy and OLT as a rescue therapy for patients with hcc. Pre-OLT hyperbilirubinemia, post-OLT requirement of transfusion, large tumor size and family history of HCC are associated with a poor survival outcome.     

Recurrence Rates After Abdominal Surgery for Complete Rectal Prolapse: A Multicenter Pooled Analysis of 643 Individual Patient Data

PURPOSE This study was designed to determine what impact surgical technique, means of access, and method of rectopexy have on recurrence rates following abdominal surgery for full-thickness rectal prolapse.METHODS Consecutive individual patient data on age, gender, surgical technique (mobilization-only, mobilization-resection-pexy, or mobilization-pexy), means of access (open or laparoscopic), rectopexy method (suture or mesh), follow-up length, and recurrences were collected from 15 centers performing abdominal surgery for full-thickness rectal prolapse between 1979 and 2001. Recurrence was defined as the presence of full-thickness rectal prolapse after abdominal surgery. Chi-squared test and Cox proportional hazards regression analysis were used to assess statistical heterogeneity. Recurrence-free curves were generated and compared using the Kaplan–Meier method and log-rank test, respectively.RESULTS Abdominal surgery consisted of mobilization-only (n = 46), mobilization-resection-pexy (n = 130), or mobilization-pexy (n = 467). There were 643 patients. After excluding center 8, there was homogeneity on recurrence rates among the centers with recurrences (n = 8) for age (hazards ratio, 0.6; 95 percent confidence interval, 0.2–1.7; P = 0.405), gender (hazards ratio, 0.6; 95 percent confidence interval, 0.1–2.3; P = 0.519), and center (hazards ratio, 0.3; 95 percent confidence interval, 0.1–1.5; P = 0.142). However, there was heterogeneity between centers with (n = 8) and without recurrences (n = 6) for gender (P = 0.0003), surgical technique (P < 0.0001), means of access (P = 0.01), and rectopexy method (P < 0.0001). The median length of follow-up of individual centers varied from 4 to 127 months (P < 0.0001). There were 38 recurrences at a median follow-up of 43 (range, 1–235) months. The pooled one-, five-, and ten-year recurrence rates were 1.06, 6.61, and 28.9 percent, respectively. Age, gender, surgical technique, means of access, and rectopexy method had no impact on recurrence rates.CONCLUSIONS Although this study is likely underpowered, the impact of mobilization-only on recurrence rates was similar to that of other surgical techniques.Presented at the meeting of The American Society of Colon and Rectal Surgeons, Dallas, Texas, May 8 to 13, 2004     

Long-Term Outlook after Successful Fibrin Glue Ablation of Cryptoglandular Transsphincteric Fistula-in-Ano

Purpose

Initial success rates for fibrin glue ablation of cryptoglandular transsphincteric fistulas have been disappointing. We examined long-term outcomes after initially successful fibrin glue ablation of cryptoglandular transsphincteric fistulas.

Methods

Retrospective review identified 36 adult patients with cryptoglandular transsphincteric fistula Tisseel VH® fibrin glue ablation that was performed from May 2000 to March 2005. Fibrin glue ablations were performed under supervision of fellowship-trained colorectal surgeons. Follow-up interval was based on time until recurrence of fistula or time of last fistula-free evaluation.

Results

Twenty-four men and 12 women patients had a mean age of 50 (range, 27–85) years. Twenty patients responded to initial fibrin glue ablation treatment. Two additional patients healed with secondary fibrin glue ablation. Sixty-six percent (22/33 patients) of cryptoglandular transsphincteric fistulas were closed at three months. Eleven patients failed fibrin glue ablation at a mean of 33 (range, 6–41) days. Seventeen of 22 short-term success patients (3 months) were available for long-term follow-up. Ninety-four percent (16/17 patients) remained healed at final long-term follow-up. The remaining patient recurred just before the six-month follow-up.

Conclusions

Despite the suboptimal early success rate of fibrin glue ablation for cryptoglandular transsphincteric fistulas, when a fistula does close for at least six months this appears to be a durable closure. A single patient recurred after appearing healed at the three-month check.

     

Effect of post-transplant double filtration plasmapheresis on recurrent focal and segmental glomerulosclerosis in renal transplant recipients

In the present study, we reviewed the effect of post-transplant double filtration plasmapheresis (DFPP) on recurrent focal segmental glomerulosclerosis (FSGS) in the transplanted kidney allograft. Sixteen patients with post-transplant recurrent FSGS were enrolled in this study. Out of 16 patients with recurrent FSGS after transplantation, five did not receive DFPP and lost their grafts, while 11 did receive DFPP and four of these patients lost their grafts. Seven patients were able to maintain normal renal function for an average observation period of 57.1 +/- 40.7 months (range 7-125 months). In five patients who had a significant reduction in urinary protein after DFPP, the urinary protein level decreased from 26.60 +/- 23.05 g/day (range 3.34-62.6 g/day) to 2.95 +/- 3.42 g/day (range 0.02-8.64 g/day) and renal function was maintained. The beneficial effects of DFPP on graft outcome were more likely to occur if the patients experienced a marked drop in urinary excretion. Thus, post-transplant DFPP appears to be effective for reducing urinary protein levels and improving long-term graft survival. With the small numbers in this trial, however, none of the findings were statistically significant. We recommend the use of post-transplant DFPP to prevent the progression of recurrent FSGS.
