Human Hepatocyte Transplantation in Patients with Hepatic Failure Awaiting a Graft
2012
<b><i>Background:</i></b> Hepatocyte transplantation (HT) has the potential to become a promising treatment to temporarily support liver function in patients with liver failure. <b><i>Methods:</i></b> Two patients, who had already received a liver transplant (LT) in the past, with an end-stage liver disease due to recurrent hepatitis C virus cirrhosis, suffering acute-on-chronic liver failure while on the waiting list for an LT, received HT as a bridge to whole-organ retransplantation. After HT and during intensive care unit admission, blood tests and ammonia levels were determined every 12 and 24 h, respectively, before and after each hepatoc…
Five-year follow-up after catheter ablation of persistent atrial fibrillation using the stepwise approach and prognostic factors for success.
2015
Background— In the meantime, catheter ablation is widely used for the treatment of persistent atrial fibrillation (AF). There is a paucity of data about long-term outcomes. This study evaluates (1) 5-year single and multiple procedure success and (2) prognostic factors for arrhythmia recurrences after catheter ablation of persistent AF using the stepwise approach aiming at AF termination. Methods and Results— A total of 549 patients with persistent AF underwent de novo catheter ablation using the stepwise approach (2007–2009). A total of 493 patients were included (Holter ECGs ≥every 6 months). Mean follow-up was 59±16 months with 2.1±1.1 procedures per patient. Single and multiple procedu…
Refractive lens exchange with the Acri. Twin asymmetric diffractive bifocal intraocular lens system
2009
PURPOSE To evaluate efficacy, safety, and predictability after refractive lens exchange (RLE) in patients who had implantation of asymmetric Acri.Twin bifocal diffractive intraocular lenses. METHODS The study comprised 130 eyes of 65 consecutive patients after RLE who had bilateral implantation of the Acri.Twin system. Eyes were divided into myopic and hyperopic groups. Binocular uncorrected distance visual acuity, best-corrected distance visual acuity (BCVA), uncorrected distance near visual acuity, and best distance-corrected near visual acuity (BCNVA) were recorded preoperatively and 6 months after surgery. RESULTS Efficacy indexes were 0.99 for myopic and 0.93 for hyperopic patients at …
Reoperation Rates Following Instrumented Lumbar Spine Fusion
2018
Study Design. A prospective cohort study. Objective. This study evaluated the cumulative reoperation rate and indications for reoperation following instrumented lumbar spine fusion (LSF). Summary of Background Data. LSF reduces disability and improves health-related quality of life for patients with several spinal disorders. The rate of instrumented LSF has drastically increased over the last few decades. The increased incidence of LSF, however, has led to increased reoperation rates. Methods. The data are based on the prospective LSF database of Tampere University Hospital that includes all elective indications for LSF surgery. A total of 433 consecutive patients (64% women, mean age 62 ye…
Reoperations after first lumbar disc herniation surgery; a special interest on residives during a 5-year follow-up
2007
Abstract Background The overall rate of operations after recurrent lumbar disc herniation has been shown to be 3–11%. However, little is known about the rate of residives. Thus the aim of this study was to explore the cumulative rates of re-operations and especially residive disc herniations at the same side and level as the primary disc herniation after first lumbar disc herniation surgery and the factors that influence the risk of re-operations over a five year follow-up study. Methods 166 virgin lumbar disc herniation patients (mean age 42 years, 57% males) were studied. Data on patients' initial disc operations and type and timing of re-operations during the follow-up were collected fro…
Chronic subdural hematoma--craniotomy versus burr hole trepanation.
2009
The authors present a series of more than 200 surgical procedures for chronic subdural hematoma in a 5-year-period. Clinical presentation and neurosurgical treatment were regarded with a special focus on the surgical technique. Between March 2003 and July 2008, 193 patients (113 male and 80 female, mean age 72.5 yrs [range 26–97 yrs]) suffering from chronic subdural hematoma were retrospectively analyzed. One-hundred-fifty-one craniotomies and 42 burr holes were performed. Forty-two craniotomy patients (27.8%) in contrast to 6 burr hole patients (14.3%) required surgical revision. A craniectomy was performed as an ultima ratio after at least 2 prior evacuations in 3 cases. Chronic subdural …
Predicting the failure in distal femur fractures.
2018
Abstract Introduction The incidence of nonunion after fractures of the distal femur is up to 6%. The distal femoral nonunion is a disabling disease that needs complex steps in his treatment. Aim of our study is to find predicting factors of non-unions. Materials and methods We retrospectively analyzed 116 cases of distal femoral fractures and 20 cases of non-unions. In both surgeries we analyzed: accuracy of reduction, stability of fixation, hardware used, residual medial or lateral bone defect, use of autologous or heterologous bone grafts. Results Malreduction, particularly axial defect, associated with unbalanced fixation, and a medial cortical bone defect of greater or lesser extent wer…
Innervated Island Flaps in Morphofunctional Vulvar Reconstruction
2000
In this article, the authors present their own experience in vulvar reconstruction following vulvectomy using two different innervated island flaps according to the size and site of the defect. Island-flap mobilization is possible thanks to the rich blood supply of the perineal region. The methods described are a "V-Y amplified sliding flap from the pubis" and a "fasciocutaneous island flap" raised from one or both gluteal folds. The V-Y amplified sliding flap from the pubis is indicated when the defect is symmetric and located anteriorly. This flap is harvested from the pubis and vascularized by the deep arterial network of the pubis. Sensory innervation is provided by branches of the ileo…
Ovarian Endometrioid-like Yolk Sac Tumor Treated by Surgery Alone, with Recurrence at 12 Years
1999
Abstract We describe the case of a stage Ia endometrioid-like yolk sac tumor (YST) of the ovary, which was originally misdiagnosed as a malignant struma ovarii and not treated with adjuvant chemotherapy. After 12 years, a contralateral dermoid cyst was excised along with a small omental nodule of partially necrotic and calcified endometrioid-like YST. No tumor was detected in several other biopsy specimens, and a peritoneal lavage was negative for tumor cells. Since there was no evidence of remaining tumor and the serum α-fetoprotein (AFP) level was normal after the second operation, the patient was followed. Serial serum AFP levels remained normal for 4 months. At a second-look laparotomy …
Salvage (tertiary) breast reconstruction after implant failure
2011
Summary Background Salvage breast reconstruction is defined as a complete revision of a previous reconstruction in case of unsatisfactory results or failure of primary or secondary breast reconstruction. We have termed this ‘tertiary breast reconstruction'. This article presents our experience with tertiary reconstructions, including the indications, method of reconstruction and outcomes. Methods A retrospective note review was performed for all patients who underwent breast reconstruction with autologous tissue under one surgeon between 2002 and 2009 at the University Hospital, Ghent. Out of these 688 patients, 54 patients (7.8%) required tertiary surgery with autologous tissue after failu…
