Selected AbstractsMicrocystic Adnexal Carcinoma: A Case Series Treated with Mohs Micrographic Surgery and Identification of Patients in Whom Paraffin Sections May Be PreferableDERMATOLOGIC SURGERY, Issue 4 2010IOULIOS PALAMARAS MD BACKGROUND Microcystic adnexal carcinoma (MAC) is a rare cutaneous tumor characterized by aggressive local infiltration, including a high propensity for perineural invasion (PNI). OBJECTIVES To report our experience in treating MAC using Mohs micrographic surgery (MMS) with frozen sections and to identify patients in whom that technique may have limitations. MATERIALS & METHODS A review of records between 1992 and 2008. RESULTS Nine patients with MAC were identified. All tumors were located on the face. PNI was noted in the diagnostic biopsies of two patients with periocular MAC, in both of whom tumor persisted after MMS. The mean duration of follow-up was 5.4 years. CONCLUSIONS MMS with frozen sections is reliable for treating primary MAC in which PNI is not present on a diagnostic biopsy. Previous surgery and PNI were associated with greater risk of persistence in periocular MAC. In these patients, it may be appropriate to consider MMS with paraffin-embedded sections, possibly as a layer after apparent clearance on frozen sections. Further excision of orbital contents should be considered in periocular MAC that infiltrate the deep orbital fat or are noted to have PNI. The authors have indicated no significant interest with commercial supporters. [source] Age-specific size of the normal adenoid pad on magnetic resonance imagingCLINICAL OTOLARYNGOLOGY, Issue 5 2000R.C. Vogler Conclusions regarding the significance and appearance of the adenoids incidentally noted on magnetic resonance (MR) scans of the brain largely rely on observations of previously published plain film data. In order to determine the age specific appearance of normal adenoid tissue as measured on sagittal T1-weighted midline MR images, we evaluated 189 patients without a history or clinical evidence of adenoid disease, who were sequentially referred for an MR scan of the brain. The thickness of the adenoid pad was measured to the nearest 1 mm along a line through the pharyngeal tubercle constructed perpendicular to the anterior clival surface. Patients were grouped according to age. Normal subjects demonstrated an age specific variation in the size of the pad with the maximal size being attained in early childhood and then steadily decreasing in later childhood and adulthood (P = 0.0001). The adenoids were largest in the 7,10 years age group (mean, 14.59 mm) and steadily declined to 4.83 mm by 60 years of age. Previous surgery had no effect on adenoid measurement (P = 0.582). Magnetic resonance scans provide an excellent method for assessing the adenoid pad. [source] Diagnosis and Management of the Lateralized Tympanic Membrane,THE LARYNGOSCOPE, Issue 12 2000Neil M. Sperling MD Abstract Objective Lateralization of the tympanic membrane (TM) is associated with significant morbidity. In a series of 14 patients, we make observations to illuminate this condition for the diagnosing and treating physician. Study Design Chart review of 14 consecutively treated patients. Methods We analyzed the presenting signs and symptoms, etiology, audiometric data, and operative findings of patients with a lateralized tympanic membrane (TM). Results The etiology was postsurgical in 13 patients (there were four aural atresia repairs and nine tympanoplasties), with 2 patients having had multiple previous surgeries. Presentation averaged more than 5 years after the latest surgery. Presenting symptoms included hearing loss in 10, tinnitus in 3, vertigo in 3, and otorrhea in 2 patients; 3 patients were nonsymptomatic at the time of presentation. The average air,bone gaps were 39 dB before treatment and 29 dB after treatment. Operative findings included cholesteatoma in six patients. Eight patients healed with the TM in the normal position; one had TM retraction, one had a TM perforation, and three had a recurrent lateralization. Conclusion The lateralized TM is primarily, but not necessarily, a complication of otological surgery. It may be associated with considerable morbidity, including hearing loss and cholesteatoma. Patients may present several years after their surgery, occasionally as an incidental finding. Surgical repair is often necessary for significant underlying disease, but re-establishment of a normal TM can be challenging. [source] Total Duodenectomy with Enteric Duct Drainage: A Rescue Operation for Duodenal Complications Occurring after Pancreas TransplantationAMERICAN JOURNAL OF TRANSPLANTATION, Issue 3 2010U. Boggi Duodenal graft complications (DGC) occur frequently after pancreas transplantation but rarely cause graft loss. Graft pancreatectomy, however, may be required when DGC compromise recipient's safety. We herein report on two patients with otherwise untreatable DGC in whom the entire pancreas was salvaged by means of total duodenectomy with enteric drainage of both pancreatic ducts. The first patient developed recurrent episodes of enteric bleeding, requiring hospitalization and blood transfusions, starting 21 months after transplantation. The disease causing hemorrhage could not be defined, despite extensive investigations, but the donor duodenum was eventually identified as the site of bleeding. The second patient was referred to us with a duodenal stump leak, 5 months after transplantation. Two previous surgeries had failed to seal the leak, despite opening a diverting stoma above the duodenal graft. Thirty-nine and 16 months after total duodenectomy with dual duct drainage, respectively, both patients are insulin-independent and free from abdominal complaints. Magnetic resonance pancreatography shows normal ducts both basal and after intravenous injection of secretin. The two cases presented herein show that when DGC jeopardize pancreas function or recipient safety, total duodenectomy with enteric duct drainage may become an option. [source] Oral contrast-enhanced sonography for the diagnosis and grading of postsurgical recurrence of Crohn's diseaseINFLAMMATORY BOWEL DISEASES, Issue 9 2008Fabiana Castiglione MD Abstract Background: Postsurgical recurrence (PSR) is very common in patients with Crohn's disease (CD) and previous surgery. Endoscopy is crucial for the diagnosis of PSR, also showing high prognostic value. Bowel sonography (BS) with or without oral contrast enhancement (OCBS) is accurate for CD diagnosis but its role in PSR detection and grading is poorly investigated. The aim was to evaluate the diagnostic accuracy of BS and OCBS for PSR compared to the endoscopical Rutgeerts's grading system. Methods: We prospectively performed endoscopy, BS, and OCBS in 40 CD patients with previous bowel resection to provide evidence of possible PSR. Endoscopy, BS, and OCBS were executed 1 year after surgery, with PSR diagnosis and grading made in accordance with Rutgeerts. BS and OCBS were considered suggestive for PSR in the presence of bowel wall thickness (BWT) >3 mm. OCBS was performed after ingestion of 750 mL of polyethylene glycol (PEG). Also, a receiver operating characteristic (ROC) curve was constructed in order to define the best cutoff of BWT to discriminate mild from severe PSR (grade 0,2 versus 3,4 of Rutgeerts) for both BS and OCBS. Results: In all, 22 out of the 40 CD showed an endoscopic evidence of PSR (55%). A severe PSR was present in 14 patients (64%). Sensitivity, specificity, and positive and negative predictive values were 77%, 94%, 93%, and 80% for BS, and 82%, 94%, 93%, and 84% for OCBS. On the ROC curve a BWT >5 mm showed sensitivity, specificity, and positive and negative predictive values of 93%, 96%, 88%, and 97% for the diagnosis of severe PSR at BS, while a BWT >4 mm was the best cutoff differentiating the mild from the severe CD recurrence for OCBS, with a sensitivity, specificity, and positive and negative predictive values of 86%, 96%, 97%, and 79%, respectively. Conclusions: Both BS and OCBS show good sensitivity and high specificity for the diagnosis of PSR in CD, with a BWT >5 mm for BS and BWT >4 mm for OCBS strongly indicative of severe endoscopic PSR. Accordingly, these techniques could replace endoscopy for the diagnosis and grading of PSR in many cases. (Inflamm Bowel Dis 2008) [source] Forensic Considerations in Cases of Neurofibromatosis,An OverviewJOURNAL OF FORENSIC SCIENCES, Issue 5 2007Roger W. Byard M.B.B.S. Abstract:, Neurofibromatosis types 1 and 2 are inherited neurocutaneous disorders characterized by a variety of manifestations that involve the circulatory system, the central and peripheral nervous systems, the skin, and the skeleton. Significant reduction in lifespan occurs in both conditions often related to complications of malignancy and hypertension. Individuals with these conditions may also be the subject of medicolegal autopsy investigation if sudden death occurs. Unexpected lethal events may be associated with intracranial neoplasia and hemorrhage or brainstem compression. Vasculopathy with fibrointimal proliferation may result in critical reduction in blood flow within the coronary or cerebral circulations, and aneurysmal dilatation may be associated with rupture and life-threatening hemorrhage. An autopsy approach to potential cases should include review of the history/hospital record, liaison with a clinical geneticist (to include family follow-up), a full external examination with careful documentation of skin lesions and nodules, measurement of the head circumference in children, photography, possible radiologic examination, a standard internal autopsy examination, documentation of the effects of previous surgery and/or chemo/radiotherapy, examination for specific tumors, specific examination and sampling of vasculature (renal, cerebral, and cardiac), formal neuropathologic examination of brain and spinal cord, possible examination of the eyeballs, examination of the gastrointestinal tract, histology to include tumors, vessels, gut, and bone marrow, toxicological testing for anticonvulsants, and sampling of blood and tissue for possible cytogenetic/molecular evaluation if required. [source] High D-dimer levels increase the likelihood of pulmonary embolismJOURNAL OF INTERNAL MEDICINE, Issue 2 2008L. W. Tick Abstract. Objective., To determine the utility of high quantitative D-dimer levels in the diagnosis of pulmonary embolism. Methods., D-dimer testing was performed in consecutive patients with suspected pulmonary embolism. We included patients with suspected pulmonary embolism with a high risk for venous thromboembolism, i.e. hospitalized patients, patients older than 80 years, with malignancy or previous surgery. Presence of pulmonary embolism was based on a diagnostic management strategy using a clinical decision rule (CDR), D-dimer testing and computed tomography. Results., A total of 1515 patients were included with an overall pulmonary embolism prevalence of 21%. The pulmonary embolism prevalence was strongly associated with the height of the D-dimer level, and increased fourfold with D-dimer levels greater than 4000 ng mL,1 compared to levels between 500 and 1000 ng mL,1. Patients with D-dimer levels higher than 2000 ng mL,1 and an unlikely CDR had a pulmonary embolism prevalence of 36%. This prevalence is comparable to the pulmonary embolism likely CDR group. When D-dimer levels were above 4000 ng mL,1, the observed pulmonary embolism prevalence was very high, independent of CDR score. Conclusion., Strongly elevated D-dimer levels substantially increase the likelihood of pulmonary embolism. Whether this should translate into more intensive diagnostic and therapeutic measures in patients with high D-dimer levels irrespective of CDR remains to be studied. [source] Infliximab dependency in children with Crohn's diseaseALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 7 2009D. DURICOVA Summary Background, Recently, infliximab dependency has been described. Aim, To assess frequency of ID in 82 consecutive Crohn's disease children treated with infliximab 2000,2006 and to describe clinical and genetic predictors of long-term infliximab response. Methods, A phenotype model of infliximab dependency was used to assess treatment response: ,immediate outcome' (30 days after infliximab start) , complete/partial/no response. ,Long-term outcome': (i) prolonged response: maintenance of complete/partial response; (ii) infliximab dependency: relapse ,90 days after intended infliximab cessation requiring repeated infusions to regain complete/partial response or need of infliximab >12 months to sustain response. Polymorphisms TNF -308 A>G, TNF -857 C>T, Casp9 93 C>T, FasL -844 C>T, LTA 252 C>T and CARD15 (R702W, G908R, 1007fs) were analysed. Results, Ninety-four per cent of children obtained complete/partial response. In long-term outcome, 22% maintained prolonged response, 12% had no response, while 66% became infliximab dependent. Perianal disease and no previous surgery were associated with infliximab dependency (OR 5.34, 95% CI: 1.24,22.55; OR 6.7, 95% CI: 1.67,26.61). No association was found with studied polymorphisms. The cumulative probability of surgery 50 months after starting infliximab was 10% in infliximab dependency, 30% in prolonged responders and 70% in nonresponders (P = 0.0002). Conclusions, Sixty-six per cent of children became infliximab dependent. Perianal disease and no surgery prior to infliximab were associated with infliximab dependency phenotype. [source] Clinical and urodynamic features of intrinsic sphincter deficiencyNEUROUROLOGY AND URODYNAMICS, Issue 4 2003Cinzia Pajoncini Abstract Aims A prospective analysis of 92 patients with genuine stress incontinence was performed to identify the clinical and urodynamic features of intrinsic sphincter deficiency (ISD). Methods We divided the patients into two categories: 50 patients affected by pure ISD as they had severe stress incontinence and no urethral mobility; 42 patients suffering from stress urinary incontinence without ISD as they had mild stress incontinence and marked urethral hypermobility. Cystometry was normal in all patients. The presence/absence of ISD was considered the dependent variable and was correlated against the following independent variables: age, vaginal deliveries, menopause, previous urogynecological surgery and/or hysterectomy, supine stress test, irritative and/or obstructive symptoms, Valsalva leak point pressure (VLPP), maximum urethral closure pressure (MUCP), urethral functional length (UFL), and leakage during cystometry. Results The statistical analysis showed close correlations between ISD and age (P,<,0.001), menopausal status (P,<,0.001), previous surgery (P,<,0.0001), supine stress test (P,<,0.0001), leakage during cystometry (P,<,0.001), and UFL (P,<,0.01). The VLPP was below the cut-off value (,60 cm H2O) in 70% of ISD patients (P,<,0.0001), whereas the MUCP in 50% of ISD patients (P,<,0.0001). Multiple logistic analysis showed that lower VLPP, lower MUCP, and previous surgery correlate more significantly with ISD. After backward conditional stepwise logistic regression, the odds ratio of having ISD were VLPP,=,2.3, MUCP,=,7.7, VLPP + MUCP,=,62.8. Conclusions ISD is related to the presence of a more severe clinical picture and case history, but the most significant independent variables are the VLPP and MUCP. Neurourol.

[source] Innovative Techniques for Placement of Implantable Cardioverter-Defibrillator Leads in Patients with Limited Venous Access to the HeartPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 2 2006BRYAN C. CANNON Background: Because of venous occlusion, intracardiac shunting, previous surgery, or small size placement of implantable cardioverter-defibrillator (ICD) leads may not be possible using traditional methods. The purpose of this study was to evaluate and describe innovative methods of placing ICD leads. Methods: The records of all patients undergoing ICD implantation at our institution were reviewed to identify patients with nontraditional lead placement. Indications for ICD, method of lead and coil placement, defibrillation thresholds, complications, and follow-up results were reviewed retrospectively. Results: Eight patients (aged 11 months to 29 years) were identified. Six patients with limited venous access to the heart (four extracardiac Fontan, one bidirectional Glenn, one 8 kg 11-month-old) underwent surgical placement of an ICD coil directly into the pericardial sac. A second bipolar lead was placed on the ventricle for sensing and pacing. Two patients with difficult venous access had a standard transvenous ICD lead inserted directly into the right atrium (transatrial approach) and then positioned into the ventricle. All patients had a defibrillation threshold of <20 J, although one patient required placement of a second coil due to an elevated threshold. There have been no complications and two successful appropriate ICD discharges at follow-up (median 22 months, range 5,42 months). Conclusions: Many factors may prohibit transvenous ICD lead placement. Nontraditional surgical placement of subcutaneous ICD leads on the pericardium or the use of a transatrial approach can be effective techniques in these patients. These procedures can be performed at low risk to the patient with excellent defibrillation thresholds. [source] Endoscopic Transnasal Craniotomy and the Resection of Craniopharyngioma,THE LARYNGOSCOPE, Issue 7 2008Aldo C. Stamm MD Abstract Objectives/Hypothesis: To describe the utility of a large transnasal craniotomy and its reconstruction in the surgical management of patients with craniopharyngioma. Study Design: Observational retrospective cohort study. Methods: Retrospective review of patients treated in an academic neurosurgery/rhinology practice between 2000 and 2007. Patient characteristics (age, sex, follow-up), tumor factors (size, position extension, previous surgery), type of repair (pedicled mucosal flaps, free mucosal grafts), and outcomes (visual, endocrine, and surgical morbidity) were defined and sought in patients who had an entirely endoscopic resection of extensive craniopharyngioma (defined as requiring removal of the planum sphenoidale in addition to sella exposure in the approach). Results: Seven patients had an entirely endoscopic resection of extensive craniopharyngioma during the study period. Mean age was 23.4 years (standard deviation ± 16.3). Mean tumor size was 3.2 cm (standard deviation ± 2.0). The majority of these pathologies had extensive suprasellar disease, and two (28.6%) had ventricular disease. Cerebrospinal fluid leak rate was 29% (2 of 7). These leaks occurred only in reconstructions with free mucosal grafts. There were no cerebrospinal fluid leaks in patients who had vascularized pedicled septal flap repairs. Conclusions: The endoscopic management of large craniopharyngioma emphasizes recent advancements in endoscopic skull base surgery. The ability to provide exposure through a large (4 cm+) transnasal craniotomy, near-field assessment of neurovascular structures, and the successful reconstruction of a large skull defect have significantly advanced the field in the past decade. The use of a two-surgeon approach and bilateral pedicled septal mucosal flaps have greatly enhanced the reliability of this approach. [source] Etiology of Late Free Flap Failures Occurring After Hospital Discharge,THE LARYNGOSCOPE, Issue 11 2007Mark K. Wax MD Abstract Objectives: Vascular compromise of free flaps most commonly occurs in the immediate postoperative period in association with failure of the microvascular anastomosis. Rarely do flaps fail in the late postoperative period. It is not well understood why free flaps can fail after 7 postoperative days. We undertook a case review series to assess possible causes of late free flap failure. Study Design: Retrospective review at two tertiary referral centers: Oregon Health Sciences University and University of Alabama at Birmingham. Methods: A review of 1,530 flaps performed in 1,592 patients between 1998 and 2006 were evaluated to identify late flap failure. Late flap failure was defined as failure occurring after postoperative day 7 or on follow-up visits after hospital discharge. A prospective database with the following variables was examined: age, medical comorbidities, postreconstructive complications (fistula or infection), hematoma, seroma, previous surgery, radiation therapy, intraoperative findings at the time of debridement, nutrition, and, possibly, etiologies. Results: A total of 13 patients with late graft failure were identified in this study population of 1,530 (less than 1%) flaps; 6 radial forearm fasciocutaneous flaps, 2 rectus abdominis myocutaneous flaps, 4 fibular flaps, and 1 latissimus dorsi myocutaneous flap underwent late failure. The time to necrosis was a median of 21 (range, 7,90) days. Etiology was believed to possibly be pressure on the pedicle in the postoperative period in four patients (no sign of local wound issues at the pedicle), infection (abscess formation) in three patients, and regrowth of residual tumor in six patients. Loss occurring within 1 month was more common in radial forearm flaps and was presented in the context of a normal appearing wound at the anastomotic site, as opposed to loss occurring after 1 month, which happened more commonly in fibula flaps secondary to recurrence. Conclusion: Although late free flap failure is rare, local factors such as infection and possibly pressure on the pedicle can be contributing factors. Patients presenting with late flap failure should be evaluated for residual tumor growth. [source] Recent Trends in Early Outcome of Adult Patients after Heart Transplantation: A Single-institution Review of 251 Transplants Using Standard Donor Organs,AMERICAN JOURNAL OF TRANSPLANTATION, Issue 6 2002Feng-Chun Tsai Older age, prior transplantation, pulmonary hypertension, and mechanical support are commonly seen in current potential cardiac transplant recipients. Transplants in 436 consecutive adult patients from 1994 to 1999 were reviewed. There were 251 using standard donors in 243 patients (age range 18,69 years). To emphasize recipient risk, 185 patients who received a nonstandard donor were excluded from analysis. The indications for transplant were ischemic heart disease (n = 123, 47%), dilated cardiomyopathy (n = 82, 32%), and others (n = 56, 21%). One hundred and forty-nine (57%) recipients were listed as status I; 5 and 6% were supported with an intra-aortic balloon and an assist device, respectively. The 30-d survival and survival to discharge were 94.7 and 92.7%, respectively; 1-year survival was 89.1%. Causes of early death were graft failure (n = 6), infection (n = 4), stroke (n = 4), multiorgan failure (n = 3) and rejection (n = 2). Predictors were balloon pump use alone (OR = 11.4, p =,0.002), pulmonary vascular resistance > 4 Wood units (OR = 5.7, p =,0.007), pretransplant creatinine > 2.0 mg/dL (OR = 6.9, p =,0.004) and female donor (OR = 8.3, p =,0.002). Recipient age and previous surgery did not affect short-term survival. Heart transplantation in the current era consistently offers excellent early and 1-year survival for well-selected recipients receiving standard donors. Early mortality tends to reflect graft failure while hospital mortality may be more indicative of recipient selection. [source] Anal stenosis: use of an algorithm to provide a tension-free anoplastyANZ JOURNAL OF SURGERY, Issue 5 2010Zeev Duieb Abstract Background:, Anal stenosis is a debilitating condition that often is iatrogenic in cause. Various surgical procedures to manage this problem have been described. The present study evaluates the use of different anoplasty techniques in a series of 11 patients with anal stenosis. To the best of the authors' knowledge, this is the first study to provide a stepwise algorithm for the anoplasty techniques used. Methods:, A series of 11 patients were evaluated for presenting symptoms, cause of anal stenosis, type of anoplasty used, complications and post-operative success in relieving symptoms. All operations were performed by one surgeon in three hospitals, and were followed up by the same surgeon and by a surgical registrar. Results:, The most common presenting symptoms were constipation and decreasing calibre of stool. The main causes of anal stenosis were previous surgery, neoplasia and fissure. Transverse closure, Y-V and diamond advancement flaps were used in an escalating manner to deal with increasing severity of stenosis. All 11 patients had some level of improvement in symptoms post-operatively. There were no long-term complications. Conclusion:, Anoplasty is a safe and successful option in the treatment of anal stenosis, and this stepwise algorithm takes the guesswork out of choosing the most appropriate procedure for each patient. [source] Efficacy of repeat hepatic resection for recurrent hepatocellular carcinomasANZ JOURNAL OF SURGERY, Issue 10 2009Yasuhiko Nagano Abstract Background:, This study evaluated the efficacy of repeat hepatic resection for recurrent hepatocellular carcinoma (HCC) and the clinicopathological factors influencing overall survival after resection. Methods:, From 1992 to 2005, 231 patients underwent curative hepatic resection for HCC at Yokohama City University, Japan. Of these, 105 patients developed intrahepatic recurrence, and 24 repeat hepatectomies were performed for recurrent HCC. Survival data were analysed, and prognostic factors for repeat hepatic resection were determined. Results:, The overall cumulative 1-, 3- and 5-year survival rates and the median survival time of the patients after initial hepatic resection (n= 231) did not differ from those of the patients after repeat hepatic resection (n= 24), with values of 91.3, 70.2 and 49.1%, and 57 months, versus 91.7, 73.1 and 50.9%, and 61.5 months, respectively (P= 0.875). The operative time and blood loss in patients who underwent repeat hepatic resection did not differ from those who underwent primary resection. Multivariate analysis identified portal invasion at the first hepatic resection and a disease-free interval of ,1.5 years after primary hepatic resection as independent risk factors for survival after repeat hepatic resection. The 12 patients who did not show either of the two prognostic factors had 3- and 5-year survival rates of 91.7 and 68.8%, respectively, after repeat hepatic resection. Conclusions:, Our findings suggest repeat hepatic resection as the treatment of choice for recurrent HCC patients without portal invasion at the first resection whose recurrence develops after a disease-free interval of >1.5 years since the previous surgery. [source] Preoperative prediction of long-term outcome following laparoscopic fundoplicationANZ JOURNAL OF SURGERY, Issue 7 2002Colm J. O'Boyle Background: Although long-term outcomes following laparoscopic fundoplication for gastro-oesophageal disease have now been reported as very satisfactory, a small, but important, minority of patients are unhappy with the outcome, often due to recurrent reflux symptoms or new-onset dysphagia. In this study, we sought to establish whether various parameters that can be determined before surgery, can predict the long-term outcome of surgery. Methods: Data collected prospectively were evaluated to determine factors that were associated with outcome at 5 years following laparoscopic fundoplication. Inclusion criteria were complete preoperative assessment data and 5-year follow-up data. Data examined included information on preoperative age, sex, weight, home address, health insurance status, duration of reflux symptoms, previous surgery, operating surgeon, endoscopy and 24-h pH monitoring. In addition, lower oesophageal sphincter resting and residual relaxation pressures were evaluated before and after surgery. The postoperative symptoms of heartburn and dysphagia, as well as overall satisfaction 5 years following surgery was determined using a 0,10 visual analogue scale. The association of the pre- and perioperative factors and outcome at 5 years was determined by univariate and linear regression analysis. Results: Two hundred and sixty-two patients from an overall experience of over 1000 laparoscopic anti-reflux procedures met the entry criteria. There was no association between patient address, age, weight, duration of symptoms, the presence of endoscopically proven oesophagitis, operating surgeon, the necessity for conversion to an open procedure, change in lower oesophageal sphincter residual relaxation pressure and the outcome parameters. Using univariate analysis, a higher heartburn score was associated with previous abdominal surgery, female sex, no private health insurance, and a normal preoperative 24-h pH study. A higher dysphagia score was associated with a normal preoperative pH study, a postoperative increase in lower oesophageal sphincter resting pressure of more than 6 mmHg, and previous abdominal surgery. Overall satisfaction with the outcome at 5 years was higher among male patients, private patients, patients who had a hiatus hernia, and patients who had an abnormal preoperative pH study. Linear regression analysis confirmed that private insurance, male sex, and the absence of previous abdominal surgery, were the strongest predictors of an improved heartburn score, whereas male sex and private health insurance were the strongest predictors of greater satisfaction with the overall outcome. Conclusions: There are parameters that can be assessed before or during laparoscopic Nissen fundoplication that correlate with late outcome parameters. In particular, male patients and those from higher socioeconomic groups appear to have a better long-term outcome. [source] Impact of tumour volume on surgical and pathological outcomes after robot-assisted radical cystectomyBJU INTERNATIONAL, Issue 7 2008Bertram Yuh OBJECTIVE To report on the influence that bladder tumour volume has on operative and pathological outcomes after robotic-assisted radical cystectomy (RARC, a minimally invasive alternative to open cystectomy for treating bladder cancer), as with the lack of tactile feedback in RARC tumour volume might compromise the outcome. PATIENTS AND METHODS Between 2005 and 2007, 54 consecutive patients had RARC at one institution. CT urograms were obtained in all patients for staging purposes and to evaluate hydronephrosis. Patients were separated into two groups based on pathological tumour dimensions. Once selected into two-dimensional (2D, flat) or 3D (bulky) tumour groups the patients were compared for operative and pathological variables. RESULTS The mean age of all patients was 67 years; 19 had tumours classified as 2D and 35 as 3D. There were no statistical differences in age, sex, body mass index, American Society of Anesthesiologists score, previous surgery, mean hospital stay, or estimated blood loss between the groups. The difference in operative duration for bladder removal was almost statistically significant (P = 0.077). Intraoperative transfusion was more common in the 3D group (P = 0.044); 43% of patients in the 3D group had hydronephrosis, vs only 16% in the 2D group. 3D tumours were more likely to be higher stage (P = 0.051). All positive margins in the patient were in the 3D group (P = 0.04); no patients with ,T2 disease had a positive surgical margin. CONCLUSIONS Bulky tumours removed with RARC might be associated with an increased rate of intraoperative transfusion, higher stage disease, and higher rate of margin positivity. In patients with large-volume tumours on preoperative assessment, wider dissection of perivesical tissue might decrease the margin-positive rates. [source] Injectable polydimethylsiloxane for treating incontinence in children with the exstrophy-epispadias complex: long-term resultsBJU INTERNATIONAL, Issue 4 2006Tariq Burki In this section authors from the UK describe their experience with plastic injections for treating incontinence in children with the exstrophy-epispadias complex, finding that in the long term the success rate was reasonable, although the injections often needed to be repeated. Authors from Brazil present an analysis of anomalies of the epididymis and processus vaginalis in human fetuses, and in patients with cryptorchidism treated and untreated with hCG. OBJECTIVE To present our experience with the use of injectable polydimethylsiloxane (MacroplastiqueTM, Uroplasty, Minneapolis, MI, USA) for treating incontinence in children with the exstrophy-epispadias complex (EEC), as incontinence continues to be a challenging problem in such children, and although the primary management of EEC has developed over the last few decades, with early closure and reconstruction of the penis, achieving satisfactory continence status remains elusive. PATIENTS AND METHODS We retrospectively reviewed the hospital records of 52 patients (41 boys and 11 girls, mean age at first injection 6.6 years, range 3.6,16.7) with EEC who had injections with Macroplastique between January 1991 and February 2004; 34 had bladder exstrophy and 18 primary epispadias. For this study we defined success as complete dryness with no use of pads or nappies. Improvement was defined as being occasionally wet but with dry intervals lasting ,,4 h. RESULTS The mean (range) follow-up was 4.6 (0.5,9) years. Twenty patients had one injection, 10 had two, 13 had three, six had four, two had six and one had seven injections. In most patients a maximum of three injections predicted the outcome. The injection of Macroplastique was successful in nine patients (17%; with an annual follow-up, two at 1,2 years, three at 2,5 years and four at >5 years), whilst 17 (33%) improved significantly (one at <1 year, two at 1,2 years, eight at 2,5 years and six at >5 years). Those patients comprised five of 18 (27%) with epispadias and four of 34 (12%) with exstrophy. A history of previous surgery and gender had no significant effect on the outcome. Overall half the patients benefited from the procedure. CONCLUSIONS This series confirms that injection with Macroplastique is minimally invasive, durable in significantly many patients and has a reasonable success rate. A history of previous surgery and gender had no significant effect on the outcome. Patients with epispadias are more likely to benefit from an injection with Macroplastique than those with bladder exstrophy. A maximum of three injections is predictive with reasonable certainty of any benefit from the procedure.

Purpose:,To compare, in the same individuals, the safety and efficacy of laser in situ keratomileusis (LASIK) in eyes with and without previous retinal detachment surgery. Methods:,In a prospective clinical trial, seven myopic patients who had previously undergone scleral buckling surgery in one eye underwent conventional LASIK surgery in both eyes. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction, Orbscan topography and pachymetry were recorded before and 1, 3, 6 and 12 months after surgery. The eyes were divided into two groups: group 1 consisted of eyes that had undergone previous surgery for retinal detachment, and group 2 consisted of the fellow eyes of the same patients, which had not undergone any previous ocular surgery. Student's t -test for match-paired data was used to evaluate the significance of differences. Results:,LASIK was performed successfully in all patients. The UCVA improved in all eyes in both groups. The mean change in the spherical equivalent between 1 and 12 months after LASIK surgery was 1.7 ± 1.1 and 0.6 ± 0.5 diopter in groups 1 and 2, respectively (p = 0.019). Conclusion:,LASIK may be considered for treatment of myopia in eyes that have had previous surgery for retinal detachment. However, the risk of regression may be higher in such eyes than in eyes with no previous scleral buckling surgery. [source] Correction of involutional lower eyelid medial ectropion with transconjunctival approach retractor plication and lateral tarsal stripACTA OPHTHALMOLOGICA, Issue 2 2006Kenneth C. S. Fong Abstract. Aim:,We describe the technique and our results in managing lower eyelid involutional medial ectropion using a combination of lateral tarsal strip to address horizontal eyelid laxity, and transconjunctival inferior retractor plication to address inferior retractor dehiscence. Methods:,Patients with symptoms of epiphora or signs of medial ectropion were offered this procedure. All had the following characteristics: medial lower eyelid eversion, punctal eversion >3 mm, medial canthal tendon laxity <4 mm, significant horizontal eyelid laxity and lacrimal systems that were patent to syringing. Results:,A total of 24 eyelids of 17 patients underwent this procedure over a 12-month period. The mean age of the patients was 79.7 years; 11 were male and six were female. The mean follow-up time was 18 months. Two eyes had undergone previous surgery. All patients had restoration of the eyelid margin to the globe and relief of symptoms. No complications were noted. Discussion:,These results suggest that excision of posterior lamellar tissue is not necessary for correction of involutional medial ectropion. Transconjunctival plication or reattachment of retractors is easy to perform and allows for the repair of more than the medial portion of the retractors if required. [source] The role of 18F-FDOPA and 18F-FDG,PET in the management of malignant and multifocal phaeochromocytomasCLINICAL ENDOCRINOLOGY, Issue 4 2008D. Taďeb Summary Background,18F-DOPA has emerged as a promising tool in the localization of chromaffin-tissue-derived tumours. Interestingly, phaeochromocytomas (PHEO) are also FDG avid. Aim and methods,The aim of this study was to retrospectively evaluate the results of 18F-FDOPA and/or 18F-FDG,PET in patients with PHEO and paragangliomas (PGLs) and to compare the outcome of this approach with the traditional therapeutic work-up. Nine patients with non-MEN2 related PHEO or PGL were evaluated. At the time of the PET studies, the patients were classified into three groups based on their clinical history, conventional and SPECT imaging. The groups were malignant disease (n = 5, 1 VHL), apparently unique tumour site in patients with previous surgery (n = 1, SDHB) and multifocal tumours (n = 3, 1 VHL, 1 SDHD). 18F-FDOPA and 18F-FDG,PET PET/CT were then performed in all patients. Results, PET successfully identified additional tumour sites in five out of five patients with metastatic disease that had not been identified with SPECT + CI. Whilst tumour tracer uptake varied between patients it exhibited a consistently favourable residence time for delayed acquisitions. 18F-FDOPA uptake (SUVmax) was superior to 18F-FDG uptake in cases of neck PGL (three patients, four tumours). If only metastatic forms and abdominal PGLs were considered, 18F-FDG provided additional information in three cases (two metastatic forms, one multifocal disease with SDHD mutation) compared to 18F-FDOPA. Conclusions, Our results suggest that tumour staging can be improved by combining 18F-FDOPA and 18F-FDG in the preoperative work-up of patients with abdominal and malignant PHEOs. 18F-FDOPA is also an effective localization tool for neck PGLs. MIBG however, still has a role in these patients as MIBG and FDOPA images did not completely overlap. [source] Spondylodiscitis due to Propionibacterium acnes: report of twenty-nine cases and a review of the literatureCLINICAL MICROBIOLOGY AND INFECTION, Issue 4 2010I. Uçkay Clin Microbiol Infect 2010; 16: 353,358 Abstract Propionibacterium acnes is the most frequent anaerobic pathogen found in spondylodiscitis. A documented case required microbiological proof of P. acnes with clinical and radiological confirmation of inflammation in a localized region of the spine. Microbiological samplings were obtained by surgery or aspiration under radiological control. Twelve males and 17 females (median age, 42 years) with spondylodiscitis due to P. acnes were diagnosed within the last 15 years. Three patients were immunosuppressed. All patients reported back pain as the main symptom, and most were afebrile. Three patients had a peripheral neurological deficit, one a motor deficit, and two a sensory deficit attributable to the infection; and six patients had an epidural abscess. The most frequent risk factor was surgery, which was present in the history 28 of 29 (97%) patients. The mean delay between spinal surgery and onset of disease was 34 months, with a wide range of 0,156 months. Osteosynthesis material was present in twenty-two cases (76%). In 24 (83%) patients, additional surgery, such as débridement or spondylodesis, was performed. Previous osteosynthesis material was removed in 17 of the 22 (77%) patients where it was present. Total cure was reported in all patients, except one, after a mean duration of antibiotic therapy of 10.5 weeks (range, 2,28 weeks). In conclusion, spondylodiscitis due to P. acnes is an acute infection closely related to previous surgery. The most prominent clinical feature is pain, whereas fever is rare, and the prognosis is very good. [source] | ||||||||||
