    Early identification of recipients with progressive histologic recurrence of hepatitis C after liver transplantation

    HEPATOLOGY, Issue 5 2000
    Raghavakaimal Sreekumar
    Approximately half of patients undergoing liver transplantation (LT) for hepatitis C virus (HCV) develop histologic evidence of recurrence within the first postoperative year. Early identification of recipients at risk for more severe recurrence of HCV may be useful in selecting patients for antiviral therapy. We determined whether recipients at greatest risk for more severe recurrence of HCV can be identified by pre- and/or early post-LT HCV-RNA levels in serum or tissue. Serum and tissue samples were prospectively collected pre-LT and at 7 days, 4 months, 1 year, and at 3 years posttransplantation from patients undergoing LT for HCV. Hepatitis activity index (HAI) and fibrosis stage (FS) were assessed in all liver biopsies. Forty-seven patients (32 men) were studied. Higher HCV-RNA levels at 4 months post-LT (,109 copies/mL, n = 29) were associated with higher HAI at 1 year and at 3 years post-LT. The HAI seen on protocol biopsies at 4 months correlated significantly with fibrosis stage (FS) at 1 year (r = .56, P , .001) and 3 years (r = .53, P = .002). Higher HCV-RNA levels at 7 days and 4 months post-LT were sensitive (66% and 84%, respectively) and specific (92% and 63%, respectively) in identifying recipients with an HAI greater than 3 at 3 years. Higher pre- and early post-LT HCV-RNA levels are associated with more severe recurrence of HCV. The correlation of early HAI with subsequent FS suggests that higher mean HAI will eventually translate into more advanced stages of fibrosis. Patients at risk for more severe post-LT recurrence of HCV can be identified by early posttransplant HCV-RNA levels. [source]

    Systematic pelvic floor training for lower urinary tract symptoms post-prostatectomy: a randomized clinical trial

    INTERNATIONAL JOURNAL OF UROLOGICAL NURSING, Issue 1 2008
    Joanne P. Robinson
    Abstract Because the majority of prostate cancers are diagnosed in the local or regional stages, radical prostatectomy is a treatment of choice for many patients, particularly men younger than 65 years of age. However, radical prostatectomy carries a significant risk of lower urinary tract symptoms (LUTS) and may also impair quality of life. The aim of the study was to examine the effects of systematic postoperative pelvic floor training (PFT) on LUTS intensity, LUTS distress and health-related quality of life (HRQL) at 3, 6 and 12 months following radical prostatectomy. This randomized clinical trial was guided by the Theory of Unpleasant Symptoms. All participants (n = 126) received brief instructions for exercising pelvic floor muscles before surgery and the offer of a biofeedback evaluation session 1 month following catheter removal. The intervention group (n = 62) received an additional 4 weeks of PFT immediately following catheter removal. Intervention and control groups both reported steady declines in the intensity and distress associated with LUTS, but no between-group differences were found. Similarly, no between-group differences were found in impact on HRQL; however, the pattern of HRQL impact differed by group (p < 0·01) in the direction of greater impairment over time for the control group. LUTS intensity, LUTS distress and negative effects on HRQL decline for many radical prostatectomy patients over the first postoperative year; however, improvement does not occur in all patients. Further research is needed to improve our understanding of factors that influence development, resolution and management of LUTS following radical prostatectomy. [source]

    Third Left Pulmonary Vein with Abnormal Return Associated with Arteriovenous Fistula

    JOURNAL OF CARDIAC SURGERY, Issue 4 2008
    Ali Can Hatemi M.D., Ph.D.
    A 20-year-old woman with complaints of effort-induced dyspnea and easy fatigability was diagnosed with a third left pulmonary vein with abnormal return and arteriovenous fistula accompanied by a secundum atrial septal defect (ASD). Complete surgical repair was performed by ASD closure with a pericardial patch and triple ligation of the left vertical vein and associated third pulmonary vein. The patient was discharged on the seventh postoperative day in good health. Her last control examination was performed in the second postoperative year, revealing normal echocardiographic findings with an excellent clinical course. [source]

    Avoiding misclassification bias with the traditional Charnley classification: Rationale for a fourth Charnley class BB

    JOURNAL OF ORTHOPAEDIC RESEARCH, Issue 9 2006
    C. Röder
    Abstract Long-term follow up of patients with total hip arthroplasty (THA) revealed a marked deterioration of walking capacities in Charnley class B after postoperative year 4. We hypothesized that a specific group of patients, namely those with unilateral hip arthroplasty and an untreated but affected contralateral hip was responsible for this observation. Therefore, we conducted a study taking into consideration the two subclasses that make up Charnley class B: patients with unilateral THA and contralateral hip disease and patients with bilateral THA. A sample of 15,160 patients with 35,773 follow ups that were prospectively collected over 10 years was evaluated. The sample was categorized into four classes according to a new modified Charnley classification. Annual analyses of the proportion of patients with ambulation longer than 60 min were conducted. The traditionally labeled Charnley class B consists of two very different patient groups with respect to their walking capacities. Those with unilateral THA and contralateral hip disease have underaverage walking capacities and a deterioration of ambulation beginning 3 to 4 years after surgery. Those with bilateral THA have stable overaverage walking capacities similar to Charnley class A. An extension of the traditional Charnley classification is proposed, taking into account the two different patient groups in Charnley class B. The new fourth Charnley class consists of patients with bilateral THA and was labeled BB in order to express the presence of two artificial hip joints and to preserve the traditional classification A through C. © 2006 Orthopaedic Research Society.

    Effect of mandibular distraction osteogenesis on developing molars

    ORTHODONTICS & CRANIOFACIAL RESEARCH, Issue 4 2007
    M Kleine-Hakala
    Structured Abstract Authors,,, Kleine-Hakala M, Hukki J, Hurmerinta K Objective,,, To observe the effect of mandibular distraction osteogenesis (DO) on developing molars. Design,,, Descriptive clinical study. Setting,,, University hospital setting. Seventeen children (mean age 7.6 years) with various syndromes (hemifacial/craniofacial microsomia, Goldenhar syndrome, Treacher Collins syndrome, Nager syndrome and Pyle,Bakwin,Krida syndrome) participated. Experimental variable,,, Severely retrognathic lower jaws were distracted (mean 30 days) with an extraoral bicortically fixed DO device. Outcome measure,,, Consecutive panoramic tomograms were analysed after a mean follow-up period of 3.6 years, range 1,6.9 years. Results,,, The mandibular molars were affected by DO in 13 of the 17 patients which included 18 of 63 mandibular molars studied. Structural changes included root malformations, hindered tooth development and the destruction of tooth follicles. Positional changes such as shifted and tilted teeth were also found. Three injured teeth failed to erupt. These changes were because of splitting of the tooth follicle during the osteotomy (22%), piercing of the tooth follicle by the pin (39%) or migration of tooth germ towards the newly created bone (39%). Fifteen per cent of first molars, 43% of second molars and 31% of third molars were affected during the distraction process. Of all dental injuries, 44% were noticed while the appliance was in place. A further 17% of injuries were noted between 3 months and 1 year postoperatively and 33% during the second postoperative year. Conclusions,,, Although dental injuries are a minor disadvantage compared with the vast benefits offered by DO, focusing on these drawbacks might lead to re-consideration of the type of the device as well as the timing of DO.

    Fungus ball of the paranasal sinuses: Experience in 160 patients treated with endoscopic surgery

    THE LARYNGOSCOPE, Issue 11 2009
    Piero Nicolai MD
    Abstract Objectives/Hypothesis: Herein we present our experience in the management of fungus ball (FB) of the paranasal sinuses. Preoperative imaging strategy and findings, surgical technique, and pathologic and microbiologic results are discussed. Study Design: Retrospective chart review of patients with FB of the paranasal sinuses who underwent endoscopic surgery at the Department of Otorhinolaryngology of the University of Brescia, Italy. Methods: From January 1990 to December 2006, 160 patients with sinonasal fungus ball were treated with a purely endoscopic approach. All patients underwent preoperative computed tomography (CT) and/or magnetic resonance (MR) imaging; an endo-oral dental x-ray or orthopantomography and odontological evaluation were also performed in patients with maxillary sinus localization. All removed material was sent for pathologic and microbiologic evaluation. All patients were prospectively followed with endoscopic control every 2 months during the first postoperative year and subsequently every 6 months. Results: The patient cohort included 118 females and 42 males, with an age from 19 to 85 years (mean, 52.7 years). FB was located in the maxillary sinus in 135 (84.4%) patients; in two cases both sinuses were affected. Sphenoid and ethmoid involvement was observed in 23 (14.4%) and 1 (0.6%) patients, respectively. Simultaneous ethmoid and sphenoid involvement was found in one (0.6%) case. In all patients complete removal of fungal debris was obtained through wide sinusotomy. No recurrence was observed. Conclusions: Endoscopic surgery is a safe and effective treatment for paranasal sinuses FB. A proper imaging study by MR and/or CT can address diagnosis, which is based upon detection of fungal hyphae at histology. Laryngoscope, 2009 [source]

    Long-term great auricular nerve morbidity after sacrifice during parotidectomy,

    THE LARYNGOSCOPE, Issue 6 2009
    William R. Ryan MD
    Abstract Objectives/Hypothesis: To clarify the extent and patient perspectives of great auricular nerve (GAN) morbidity and recovery after nerve sacrifice during parotidectomy 4 to 5 years after surgery. Study Design: Prospective series. Methods: Twenty-two patients who underwent parotidectomy with GAN sacrifice and were previously studied for GAN sensory outcome during the first postoperative year. We performed light touch sensation tests on each patient to develop an ink map representing anesthesia and paresthesia in the GAN sensory territory; patients also completed an outcomes questionnaire. Results: Nineteen (86%) of 22 patients completed follow-up. One patient completed the questionnaire over the phone. The prevalence and average areas of anesthesia and paresthesia decreased since the first postoperative year according to sensory testing and patient scoring. At 4 to 5 years, 47% (9 of 19) of the patients had anesthesia, 58% (11 of 19) had paresthesia, and 26% (5 of 19) had neither anesthesia nor paresthesia during sensory testing. Patients reported that the GAN dysfunction brought them no to mild inference with their daily activities. At a mean point of 2 years, 70% (14 of 20) patients felt that their sensory symptoms had either completely abated or stabilized. Conclusions: The posterior branch of the GAN should be preserved if it does not compromise tumor resection. If this is not possible, the patient and surgeon should be comforted in that only minor, if any, long-term disability will ensue. Laryngoscope, 2009 [source]

    A Practical Guide to the Management of HCV Infection Following Liver Transplantation

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 8 2009
    K. Watt
    Hepatitis C-associated liver failure is the most common indication for liver transplantation, with virological recurrence near ubiquitous. Approximately 30% of HCV-infected recipients will die or lose their allograft or develop cirrhosis secondary to hepatitis C recurrence by the fifth postoperative year, with the proportion increasing with duration of follow-up. Strategies for minimizing the frequency of severe HCV recurrence include avoidance of older donors, early diagnosis/treatment of CMV and minimization of immunosuppression, particularly T-cell depleting therapies and pulsed corticosteroid treatment of acute cellular rejection. Patients should be offered treatment with peginterferon and ribavirin before LT if MELD , 17 or as soon as histological evidence of recurrence of HCV is apparent post-LT. Because of the high frequency of hemotoxicity and renal insufficiency, ribavirin should be dosed according to renal function. [source]

    Twenty-Year Experience With Heart Transplantation for Infants and Children With Restrictive Cardiomyopathy: 1986,2006

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 1 2008
    A. J. Bograd
    Idiopathic restrictive cardiomyopathy (RCM) is a rare cardiomyopathy in children notable for severe diastolic dysfunction and progressive elevation of pulmonary vascular resistance (PVR). Traditionally, those with pulmonary vascular resistance indices (PVRI) >6 W.U. × m2 have been precluded from heart transplantation (HTX). The clinical course of all patients transplanted for RCM between 1986 and 2006 were reviewed. Preoperative, intraoperative and postoperative variables were evaluated. A total of 23 patients underwent HTX for RCM, with a mean age of 8.8 ± 5.6 years and a mean time from listing to HTX of 43 ± 60 days. Preoperative and postoperative (114 ± 40 days) PVRI were 5.9 ± 4.4 and 2.9 ± 1.5 W.U. × m2, respectively. At time of most recent follow-up (mean = 5.7 ± 4.6 years), the mean PVRI was 2.0 ± 1.0 W.U. × m2. Increasing preoperative mean pulmonary artery pressure (PA) pressure (p = 0.04) and PVRI > 6 W.U. × m2 (,2= 7.4, p < 0.01) were associated with the requirement of ECMO postoperatively. Neither PVRI nor mean PA pressure was associated with posttransplant mortality; 30-day and 1-year actuarial survivals were 96% and 86%, respectively. Five of the seven patients with preoperative PVRI > 6 W.U. × m2 survived the first postoperative year. We report excellent survival for patients undergoing HTX for RCM despite the high proportion of high-risk patients. [source]

    Health-related quality of life during neoadjuvant treatment and surgery for localized esophageal carcinoma

    CANCER, Issue 9 2005
    Jane M. Blazeby B.Sc., M.D.
    Abstract BACKGROUND Esophagectomy has a negative influence on health-related quality of life (HRQL) during the first postoperative year, but it is not known how chemotherapy or chemoradiotherapy treatment before surgery affects HRQL. The current study examined HRQL during preoperative chemotherapy/chemoradiotherapy treatment and compared postoperative recovery of HRQL in patients undergoing combined treatment with patients undergoing surgery alone. METHODS One hundred three patients completed standardized HRQL measures before and during neoadjuvant treatment and before and after surgery. Mean HRQL scores were calculated and preoperative scores were used to model postoperative ratings using linear regression. RESULTS Deterioration in most aspects of HRQL occurred during preoperative chemotherapy. Patients proceeding to concomitant radiotherapy further deteriorated with specific problems with reflux symptoms and role function (difference between means >15, P < 0.01). After neoadjuvant treatment, but before surgery, HRQL returned to baseline levels. Six weeks after surgery, patients reported marked reductions in physical, role, and social function (difference between means > 30, P < 0.01) and increase in fatigue, nausea and emesis, pain, dyspnea, appetite loss, and coughing (difference between means > 15, P < 0.01). Recovery of HRQL was not hampered by preoperative treatment, and fewer problems with postoperative nausea, emesis, and dysphagia were reported by patients who had undergone neoadjuvant treatment compared with patients who had undergone surgery alone. CONCLUSIONS Preoperative chemotherapy or chemoradiotherapy had a negative impact on HRQL that was restored in patients proceeding to surgery. Recovery of HRQL after esophagectomy was not impaired by neoadjuvant treatment. These results supported the use of neoadjuvant treatment before surgery. Cancer 2005. © 2005 American Cancer Society.

    Molteno aqueous shunt as a primary surgical intervention for uveitic glaucoma: long-term results

    ACTA OPHTHALMOLOGICA, Issue 1 2010
    Marja-Liisa Vuori
    Abstract. Purpose:, To evaluate the efficacy of Molteno aqueous shunt as a primary surgical treatment in uveitic glaucoma. Methods:, Nonrandomized, interventional, retrospective clinical study. The intraocular pressure (IOP), survival rate and complications were analyzed in 30 patients with uveitic glaucoma treated with Molteno implant. Results:, The mean follow-up time was 59.3 ± 18.4 months. Preoperatively, the mean ± SD IOP was 32.8 ± 7.5 mmHg (range 20,48), and the mean number of medications was 3.1 ± 0.6. The mean IOP decreased significantly (p < 0.001) to 17.7 and 15 mmHg at 3 and 6 months postoperatively. The mean number of medications decreased statistically significantly (p < 0.001) from the preoperative number 3.1 to 1.9 three months postoperatively. The number of medications continued to decrease significantly up to 3 years postoperatively. The qualified success rate (Kaplan,Meier estimate) was 97%, 93%, 90% and 85% at 1, 2, 3 and 4 years, respectively. Two patients failed because of hypotony, two patients developed conjunctival erosion and one patient had corneal decompensation. Conclusions:, Molteno aqueous shunt as the first glaucoma procedure decreased IOP effectively in uveitic glaucoma. Even after 4 years, the survival estimate was quite high. The IOP decreased continuously during the first year after the surgery, and the medication was slowly tapered even up to 3 years postoperatively. It is suggested that it may be possible to postpone further surgical intervention during the first postoperative year after Molteno implantation even if the IOP is not quite optimal. [source]

    Trabeculectomy with an active postoperative regimen: results and resource utilization

    ACTA OPHTHALMOLOGICA, Issue 5 2009
    Amelie B. Taube
    Abstract. Purpose:, To evaluate intraocular pressure (IOP) and resource utilization after trabeculectomy, using an active postoperative regimen, in a Swedish population. Methods:, A retrospective analysis was performed on the patient charts of all patients who underwent trabeculectomy in a Swedish university hospital during 1 year (November 2000,December 2001). Trabeculectomy was performed in 34 eyes and trabeculectomy in combination with phacoemulsification in 10 eyes. Intraocular pressure, visual acuity, complications and numbers of injections of 5-fluorouracil, suture removal, needling procedures and visits to ophthalmologists were recorded for 2 years. Results:, Mean IOP before surgery was 30.4 mmHg (standard deviation [SD] 9.5) in eyes with capsular glaucoma and 28.7 mmHg (SD 9.3) in eyes with primary open-angle glaucoma. Mean IOP after 2 years was 15.3 mmHg (SD 3.9) in all eyes. Intraocular pressure of < 18 mmHg was achieved in 65% of the eyes after 2 years, as was IOP , 13 mmHg in 37%. Flap or suture manipulation was performed in 41 of 44 eyes. Needling procedures were carried out a mean of 2.3 times in 31 eyes. The mean number of visits to an ophthalmologist was 14.1 during the first postoperative year and 4.4 during the second. Conclusions:, The results were encouraging, with few complications and modest resource utilization. [source]

    Seizure Outcome after Resection of Supratentorial Cavernous Malformations: A Study of 168 Patients

    EPILEPSIA, Issue 3 2007
    Christian R. Baumann
    Summary:,Purpose: The optimal management of cerebral cavernous malformations (CCMs) with epileptic seizures is still a matter of debate. The aim of our study was to examine seizure outcome in the largest published series of surgically treated patients with epilepsy due to a supratentorial CCM, and to define predictors for good surgical outcome. Methods: We retrospectively studied 168 consecutive patients with a single supratentorial CCM and symptomatic epilepsy in a multicenter study. Pre- and postoperative clinical examinations, age at epilepsy onset, age at operation, type of symptoms due to the CCM (seizures, headache, hemorrhage, focal deficits), type and frequency of epileptic seizures, and the localization and size of the CCM were assessed. Seizure outcome was determined in the first, second, and third postoperative years. Results: The CCM was completely resected in all patients. More than two thirds of the patients were classified as seizure free in the first 3 postoperative years. Predictors for good seizure outcome were age older than 30 years at the time of surgery, mesiotemporal CCM localization, CCM size <1.5 cm, and the absence of secondarily generalized seizures. No mortality occurred in our series, but only mild postoperative neurologic deficits in 12 (7%) patients. Conclusions: Considering the natural history of CCMs, the favorable neurologic and seizure outcome, surgical resection of CCMs should be considered in all patients with supratentorial CCMs and concomitant epilepsy, irrespective of the presence or absence of predictors for a favorable seizure outcome.

    Nuclear survivin is associated with disease recurrence and poor survival in patients with cutaneous malignant melanoma

    HISTOPATHOLOGY, Issue 7 2007
    F Piras
    Aims:, Survivin is expressed in neoplastic cells and appears to be associated with resistance to therapy and shorter survival in various types of tumours. The aim of the present study was to determine whether nuclear or cytoplasmic expression of survivin is related to disease recurrence and overall survival of patients with Stage I and II melanoma according to the American Joint Committee on Cancer (AJCC) staging system. Methods and results:, Immunohistochemistry was performed on formalin-fixed paraffin-embedded sections of primary cutaneous melanoma from 50 patients. Survival rates were estimated using the Kaplan,Meier method and compared using the log rank test. Association of clinical variables (gender, age, tumour location, thickness, Clark level and AJCC stage) with survivin expression was analysed by Fisher's exact test. Patients with nuclear immunoreactivity for survivin had an increased risk of disease recurrence during the first three postoperative years (P < 0.05) and of death (P < 0.05). Cytoplasmic immunoreactivity was not correlated with either survival or clinical variables. Conclusions:, Nuclear presence of survivin may be an independent biomarker for disease recurrence and overall survival in patients with Stage I and II melanoma. [source]
