Recurrence Rate (recurrence + rate)
Kinds of Recurrence Rate Selected AbstractsPhenol Chemical Matricectomy Is Less Painful, with Shorter Recovery Times but Higher Recurrence Rates, Than Surgical Matricectomy: A Patient's ViewDERMATOLOGIC SURGERY, Issue 8 2010JESSICA C. HASSEL DR MED BACKGROUND Ingrown toenails have a tendency for recurrence. Operative interventions can be successful, and several procedures are in use. OBJECTIVE Retrospective evaluation, to reveal differences in postoperative pain, time to recovery, and satisfaction with the cosmetic outcome in patients treated with a phenol (PCM) or surgical matricectomy (SM). MATERIALS & METHODS All matricectomy patients at the Dermatology Department of the Ludwigshafen City Hospital between 2004 and 2008 were interviewed over the telephone. Of 72 evaluable patients with a total of 112 ingrown nail sides, 33 were treated with PCM and 39 with SM. The patient group consisted of 40.3% women, the median age was 31. RESULTS Patients after PCM indicated two points less postoperative pain on an analogue scale from 0 to 10 (p<.001). In the PCM group, more patients recovered from the operation in less than 1 week (p=.007). Patient evaluation of cosmetic outcome was not different between the groups (p=.76), but recurrence rates were significantly higher in the PCM group (31.5%, vs 6.9% in the SM group, p=.006) CONCLUSION Both matricectomies have advantages and disadvantages. We should discuss these issues with our patients to help them decide on the kind of matricectomy. The authors have indicated no significant interest with commercial supporters. [source] Terlipressin therapy with and without albumin for patients with hepatorenal syndrome: Results of a prospective, nonrandomized studyHEPATOLOGY, Issue 4 2002Rolando Ortega Vasopressin analogues associated with albumin improve renal function in hepatorenal syndrome (HRS). The current study was aimed at assessing the efficacy of the treatment, predictive factors of response, recurrence of HRS, and survival after therapy. Twenty-one consecutive patients with HRS (16 with type 1 HRS, 5 with type 2 HRS) received terlipressin (0.5-2 mg/4 hours intravenously) until complete response was achieved (serum creatinine level < 1.5 mg/dL) or for 15 days; 13 patients received intravenous albumin together with terlipressin. Twelve of the 21 patients (57%) showed complete response. Albumin administration was the only predictive factor of complete response (77% in patients receiving terlipressin and albumin vs. 25% in those receiving terlipressin alone, P = .03). Treatment with terlipressin and albumin was associated with a remarkable decrease in serum creatinine level, increase in arterial pressure, and suppression of the renin-aldosterone system. By contrast, no significant changes in these parameters were found in patients treated with terlipressin alone. Only 1 patient showed ischemic adverse effects. Recurrence of HRS occurred in 17% of patients with complete response. The occurrence of complete response was associated with an improved survival. In conclusion, terlipressin therapy reverses HRS in a high proportion of patients. Recurrence rate after treatment withdrawal is uncommon. Albumin appears to improve markedly the beneficial effects of terlipressin. [source] Recurrence of primary biliary cirrhosis and primary sclerosing cholangitis after liver transplantation in JapanHEPATOLOGY RESEARCH, Issue 2007Satoshi Yamagiwa Although there was some initial controversy, there is now a consensus that primary biliary cirrhosis (PBC) does indeed recur in both cadaveric and living donated allografts. Recurrence rate after deceased donor liver transplantation (LT) was reported to be 10.9,23% at 5 years. In the present study, we reviewed 221 PBC patients who underwent living-donor liver transplantation (LDLT) in Japan. The 5-year overall survival rate was 79%, and the rate of recurrence based on histological findings was 10% (7/70) after a median time of 36 months. Primary immunosuppression, withdrawal of corticosteroids and human leukocyte antigen matches were not associated with the recurrence. Recurrent PBC appears to have little impact on graft function and survival, but this may become a greater problem with longer follow up. It is noteworthy that the 10-year survival of primary sclerosing cholangitis (PSC) patients who underwent LDLT wasfound to be only 39.1% in Japan, whereas that of PBC was 72.9%. Factors associated with the poor prognosis include biliary strictures, hepatobiliary and colorectal malignancies, and recurrence of PSC. In our study, we reviewed 66 patients with PSC who underwent LDLT in Japan. The 5-year survival rate was 72%, and the rate of recurrence diagnosed on histological and cholangiographic findings was 25% (11/44). Well-defined diagnostic criteria and longer studies are required to characterize the nature of recurrent PSC and its impact on graft survival in more detail. [source] Cryoablation of Accessory Pathways in ChildrenPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 9 2007VOLKAN TUZCU M.D. Background: Cryoablation is utilized for septal tachycardia substrates due its safety. Considering the recent studies which reveal coronary artery stenosis related to radiofrequency ablation (RFA) in children, cryoablation may offer advantages for nonseptal accessory pathways (APs) as well. The aim of this study was to investigate the efficacy and safety of cryoablation of APs in children. Methods: A total of 39 patients (median age = 9.3 years, range 4.8 to 17.2 years) underwent cryoablation of APs. A three-dimensional, surface electrode-based navigation system (EnSite NavXÔ, St.Jude Medical Inc., St. Paul, MN, USA) is used to decrease the fluoroscopy exposure. Results: A total of 45 APs were identified. Of these APs, 23 were septal (anteroseptal, midseptal, posteroseptal) and 22 were nonseptal. Acute success rate with cryoablation was 73%. RFA was used when cryoablation failed and overall acute success rate was 84%. To assess for the effect of institutional experience, the initial 23 APs were compared to the recent 22 APs and acute success rate revealed significant improvement (57% vs. 91%). Recurrence rate was 24% during a median follow-up of 282 days. Conclusion: Cryoablation of APs is safe and yields to high acute success rates in children. It can potentially be used as the first ablation option for all APs in children. However, recurrence rate is higher compared to the RFA and there is a need for prospective comparative studies. [source] Single-dose oral fluconazole versus topical clotrimazole in patients with pityriasis versicolor: A double-blind randomized controlled trialTHE JOURNAL OF DERMATOLOGY, Issue 8 2010Mohammad DEHGHAN Abstract This study was designed to compare the therapeutic effects of topical clotrimazole and systemic fluconazole in pityriasis versicolor. A double-blind randomized controlled trial was carried out in the dermatological clinic of Gorgan, northern Iran, between April 2006 and May 2007. All consecutive patients with pityriasis versicolor were included and randomly divided into two groups. In the first group (G1), patients underwent treatment with a single dose of fluconazole capsule (400 mg) and placebo cream. In the second group (G2), patients underwent treatment with clotrimazole cream (twice daily) and placebo capsule. The course of treatment was 2 weeks. All subjects were re-evaluated 2, 4 and 12 weeks after the end of the therapeutic course. After 2 weeks, the rate of complete resolution of disease was significantly higher in G2 than G1 (49.1% vs 30%). After 4 weeks, 41 patients (81.2%) of G1 and 52 patients (94.9%) of G2 showed complete resolution. After 12 weeks, 46 patients (92%) in G1 and 45 patients (81.8%) in G2 showed complete resolution. Recurrence rate in G1 and G2 were 6% and 18.2%, respectively. No complications were seen in either group. In this study, clinical response at week 4 was greater in the clotrimazole group than the fluconazole group. Recurrence at week 12 after treatment was less with oral fluconazole than clotrimazole cream. So, for better evaluation, more studies need to be done. [source] Selective Neck Dissection in the Management of the Clinically Node-Negative Neck ,THE LARYNGOSCOPE, Issue 12 2000A. Sefik Hosal MD Abstract Objective To evaluate the efficacy of the selective neck dissection (SND) in the management of the clinically node-negative neck. Study Design Case histories were evaluated retrospectively. Methods The results of 300 neck dissections performed on 210 patients were studied. Results The primary sites were oral cavity (91), oropharyn- (30), hypopharyn- (16), and laryn- (73). Seventy-one necks (23%) were node positive on pathological e-amination. The number of positive nodes varied from 1 to 9 per side. Of necks with positive nodes, 17 (24%) had e-tracapsular spread. The median follow-up was 41 months. Recurrent disease developed in the dissected neck of 11 patients (4%). Two recurrences developed outside the dissected field. The incidence of regional recurrences was similar in patients in whom nodes were negative on histological e-amination (3%) when compared with patients with positive nodes without e-tracapsular spread (4%). In contrast, regional recurrence developed in 18% of necks with e-tracapsular spread. This observation was statistically significant. Patients having more than two metastatic lymph nodes had a higher incidence of recurrent disease than the patients with carcinoma limited to one or two nodes. Recurrence rate in the pathologically node positive (pN+) necks was comparable to recurrence in those pathologically node negative (pN0) necks in the patients who did not have irradiation. Conclusion SND is effective for controlling neck disease and serves to detect patients who require adjuvant therapy. [source] Late results of treatment of anal fistulasCOLORECTAL DISEASE, Issue 2 2007A. Sygut Abstract Objective, The aim of this paper was to analyse the results of treatment of anal fistulas retrospectively. Methods, Between 1992 and 2004, 407 patients were operated on for perianal fistula. In the follow-up period, 107 patients were lost, so 300 patients were analysed in the study. The mean follow-up time was 4.2 years. Analysed parameters included: types of surgical procedures in different kinds of fistulas and postoperative complications. Various types of surgical procedures and their effectiveness were described. Late results were assessed taking into account healing time, duration of sick leave, recurrence rate and incidence of anal sphincter dysfunction. Severity of gas and stool incontinence was assessed according to the Cleveland Clinic Incontinence Score. Results, In our study, subcutaneous fistula was diagnosed in 23.3%, inter-sphincteric in 18%, trans-sphincteric in 37.7%, supra-sphincteric in 16% and extra-sphincteric in 5% of patients. Single-tract fistulas were present in 88.7% and multi-tract fistulas were present in 11.3%. Overall, 242 patients had primary fistulas and 58 patients had recurrent fistulas. The most frequently performed procedures were cutting seton (139 patients) and radical fistulectomy (104 patients). Recurrent fistulas developed in 14.3%. Postoperative gas and/or stool incontinence was noticed in 10.7%. The recurrence rate was 5.4% in patients with primary fistula and in 51.7% patients presenting with a recurrent fistula. Gas and stool incontinence developed in 3.7% of patients with primary fistulas and in 39.7% of patients presenting with recurrent fistulas. Recurrence rate was 12% in the patients of single-tract fistulas and 32.4% in the patients of multi-tract fistulas. Postoperative gas and/or stool incontinence occurred in 8.3% of patients of single-tract fistulas and in 29.4% of patients of multi-tract fistulas. Conclusions, The complication rate was 10-fold higher in patients presenting with a recurrent fistula than in those with primary fistulas and threefold higher in patients with multi-tract fistulas than in those with single-tract fistulas. [source] Eletriptan in Migraine Patients Reporting Unsatisfactory Response to RizatriptanHEADACHE, Issue 7 2006Jerome Goldstein MD Objective.,The objective of this open-label study was to evaluate the efficacy of switching patients who had a previous unsatisfactory response to rizatriptan to eletriptan 40 mg. Background.,The characteristics of individual migraine patients can vary tremendously and can have a significant impact on treatment outcomes. In addition, clinical experience has demonstrated that the triptans are not identical or interchangeable and that patients who respond poorly or who are dissatisfied with one agent can derive benefit by being switched to another agent within the triptan class. Methods.,Patients were eligible if they met International Headache Society criteria for migraine, with a frequency of 1 to 6 migraine attacks per month, and had documented "unsatisfactory treatment response" to rizatriptan within the past year (54% on the melt formulation; 46% on tablets). Reasons for dissatisfaction with rizatriptan (>1 could be cited) included inadequate (84%) or slow onset (50%) of pain relief, high recurrence rate (69%), and lack of improvement in associated symptoms (60%). One hundred twenty-three patients were eligible for treatment. Patients were instructed to take eletriptan 40 mg as soon as they were certain that their headache was a migraine, regardless of level of pain severity (8% treated headaches that were mild). Results.,Headache response at 2 hours (first-attack data) was 64%. Absence of nausea (from baseline to 2 hours) increased from 50% to 78%, absence of photophobia from 30% to 72%, and absence of phonophobia from 39% to 77%. Functional response at 2 hours was 63%, with 41% of patients reporting normal functioning. Treatment with eletriptan 40 mg was associated with a 27% to 40% reduction in migraine attack-related functional impairment, as measured by the PQ-7. Recurrence rates were 36.6%. Overall, 72% of patients rated eletriptan as a "good-to-excellent" treatment, and 78% reported overall satisfaction with the degree of headache relief. Conclusion.,The results of this study suggest that eletriptan is an efficacious treatment option for patients who are dissatisfied with their response to rizatriptan. [source] Recurrent Peptic Ulcers in Patients Following Successful Helicobacter pylori Eradication: A Multicenter Study of 4940 PatientsHELICOBACTER, Issue 1 2004Hiroto Miwa ABSTRACT Objective., Although curative treatment of Helicobacter pylori infection markedly reduces the relapse of peptic ulcers, the details of the ulcers that do recur is not well characterized. The aim of this study is to describe the recurrence rate and specific features of peptic ulcers after cure of H. pylori infection. Methods., This was a multicenter study involving 4940 peptic ulcer patients who were H. pylori negative after successful eradication treatment and were followed for up to 48 months. The annual incidence of ulcer relapse in H. pylori -cured patients, background of patients with relapsed ulcers, time to relapse, ulcer size, and site of relapsed ulcers were investigated. Results., Crude peptic ulcer recurrence rate was 3.02% (149/4940). The annual recurrence rates of gastric, duodenal and gastroduodenal ulcer were 2.3%, 1.6%, and 1.6%, respectively. Exclusion of patients who took NSAIDs led annual recurrence rates to 1.9%, 1.5% and 1.3%, respectively. The recurrence rate was significantly higher in gastric ulcer. Recurrence rates of patients who smoked, consumed alcohol, and used NSAIDs were significantly higher in those with gastric ulcer recurrence compared to duodenal ulcer recurrence (e.g. 125 of 149 [83.9%] relapsed ulcers recurred at the same or adjacent sites as the previous ulcers). Conclusions., Curative treatment of H. pylori infection is useful in preventing ulcer recurrence. Gastric ulcer is more likely to relapse than duodenal ulcer. Recurrent ulcer tended to recur at the site of the original ulcers. [source] Recurrence rates associated with incompletely excised low-risk nonmelanoma skin cancerJOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2010Kerri E. Rieger Background: Reported recurrence rates for transected nonmelanoma skin cancer (NMSC) vary widely, and few studies have addressed recurrence of tumors followed clinically or treated with nonsurgical modalities. Methods: Retrospective review of dermatopathology records from January 1999 to January 2005 was conducted to identify biopsies or excision specimens with histologically transected basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) which were not subsequently excised. Patient and tumor characteristics associated with recurrence were analyzed in a subgroup of patients with predominantly ,low-risk' and/or minimally transected NMSCs. Prospective follow up was performed through March 31, 2008. Data was analyzed with Chi-square and Fishers exact tests and multivariate logistic regression. Results: Of 376 transected NMSCs, 27 (7.2%) recurred, including 20 (9%) of 223 BCCs and 7 (4.6%) SCCs in situ of 153 SCCs. The overall recurrence rate of the 124 minimally transected NMSCs was even lower (5.6%). Multivariate logistic regression identified three significant predictors of recurrence: tumor location on the head and neck (p = 0.041), tumor size (p = 0.00741) and superficial subtype of BCC (p = .035). Conclusions: Although surgical excision of NMSC remains the standard of care, observation or nonsurgical treatment may be acceptable in many cases of incompletely excised low-risk or minimally transected NMSCs. [source] Cryoablation for Atrioventricular Nodal Reentrant Tachycardia in Young Patients: Predictors of RecurrencePACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 9 2008NIKHIL K. CHANANI M.D. Background: Recurrence rates of atrioventricular nodal reentry tachycardia (AVNRT) after cryoablation continue to remain high despite excellent initial success rates. Our objective was to evaluate the clinical outcomes of cryoablation for AVNRT with the 4-mm and 6-mm tip cryoablation catheters in a young population and to elicit predictors of arrhythmia recurrence. Methods: We retrospectively reviewed all patients who underwent cryoablation for AVNRT at the UCSF/Stanford Pediatric Arrhythmia Center from January 2004 to February 2007. Results: One hundred fifty-four patients (age 13.7 years (3.2,24.4)) underwent cryoablation for AVNRT of which 144 patients had inducible AVNRT (123 sustained and 21 nonsustained) and 10 had presumed AVNRT. Initial success was achieved in 95% (146/154), with no difference between the 4-mm (93%) and 6-mm (98%) cryoablation catheter tips (P = 0.15). There was no permanent atrioventricular (AV) block. Transient third-degree AV block occurred in nine patients (6%), with no difference between the 4-mm (4%) and 6-mm (9%) tip (P = 0.13). AVNRT recurrence was documented in 14% in a median time of 2.5 months (0.25,20). Recurrences were lower with the 6-mm (9%) versus the 4-mm (18%) tip, but this did not reach statistical significance (P = 0.16). With univariate analysis, a longer fluoroscopy time was the only significant factor associated with recurrence. Multivariate analysis failed to identify any significant predictor of AVNRT recurrence. Conclusion: Outcomes of cryoablation for AVNRT continue to be good without the complication of AV block. We could not identify any specific parameter associated with AVNRT recurrence. Further improvements in cryoablation technique will be necessary to reduce recurrences. [source] The Preauricular Sinus: A Review of its Clinical Presentation, Treatment, and AssociationsPEDIATRIC DERMATOLOGY, Issue 3 2004Noah S. Scheinfeld M.D. Usually asymptomatic, they manifest as small dells adjacent to the external ear near the anterior margin of the ascending limb of the helix, most frequently on the right side. Preauricular sinuses can be either inherited or sporadic. When inherited, they show an incomplete autosomal dominant pattern with reduced penetrance and variable expression. They may be bilateral, increasing the likelihood of being inherited, in 25,50% of cases. Preauricular sinuses are features of other conditions or syndromes in 3,10% of cases, primarily in association with deafness and branchio-oto-renal (BOR) syndrome. When other congenital anomalies coexist with these sinuses, auditory testing and renal ultrasound should be considered. Sinuses may become infected, most commonly with gram-positive bacteria, in which case their exudates should be cultured and appropriate antibiotics administered. Recurrent infection is a clear indication for complete excision and provides the only definitive cure. Recurrence rates after surgery range from 9% to 42%. Meticulous excision by an experienced head and neck surgeon minimizes the risk of recurrence. [source] Recurrence rates of cardiac manifestations associated with neonatal lupus and maternal/fetal risk factorsARTHRITIS & RHEUMATISM, Issue 10 2009Carolina Llanos Objective Identifying the frequency of recurrent cardiac manifestations of neonatal lupus (NL) in a second child is critical to understanding the pathogenesis of anti-SSA/Ro,mediated injury and would improve counseling strategies regarding future pregnancies and power the design of clinical prevention trials. Accordingly, this study was undertaken to address the recurrence rates of cardiac NL and associated risk factors in a large US-based cohort. Methods Families enrolled in the Research Registry for Neonatal Lupus were evaluated for rates of recurrence of cardiac NL and potential risk factors, with a focus on pregnancies immediately following the birth of an affected child. Results The overall rate of recurrence of cardiac NL in 161 pregnancies of 129 mothers with anti-SSA/Ro antibodies was 17.4% (95% confidence interval 11.1,23.6%). Analysis of the potential risk factors among 129 mothers with a pregnancy immediately following the birth of a child with cardiac NL showed that the maternal diagnosis was not associated with the outcome in a subsequent pregnancy. In this group, 23% of mothers who were either asymptomatic or had an undifferentiated autoimmune syndrome, compared with 14% of mothers with systemic lupus erythematosus or Sjögren's syndrome, had a second child with cardiac NL (P = 0.25). The recurrence rate was not statistically significantly different in mothers who had taken steroids compared with those who had not taken steroids (16% versus 21%; P = 0.78). The antibody status of the mother was not predictive of outcome in subsequent pregnancies. Moreover, death of the first child with cardiac NL was not predictive of recurrence of cardiac NL in a subsequent pregnancy (P = 0.31). The risk of cardiac NL was similar between male and female children (17.2% versus 18.3%; P = 1.0). Conclusion In this cohort, the overall recurrence rate for cardiac NL was 17%. The recurrence rate appeared to be unaffected by maternal health, use of steroids, antibody status, severity of cardiac disease in the first affected child, or sex of the subsequent child. [source] Vinblastine, bleomycin, and methotrexate chemotherapy plus irradiation for patients with early-stage, favorable Hodgkin lymphomaCANCER, Issue 11 2003The experience of the Gruppo Italiano Studio Linfomi Abstract BACKGROUND The acknowledged effectiveness of vinblastine, bleomycin, and methotrexate (VBM) chemotherapy in patients with early-stage Hodgkin lymphoma has been associated with conflicting toxicity reports. METHODS One hundred forty-three patients were evaluated clinically and had favorable Stage IA or IIA Hodgkin lymphoma. Ninety-three patients were treated with the standard VBM schedule combined with extended-field radiotherapy (EF-RT), leaving the choice of the therapeutic sequence free. Fifty subsequent patients were treated with a slightly modified VBM schedule (VbMp) combined with RT limited to involved fields (IF-RT) and delivered only after the end of chemotherapy. In the VbMp schedule, intervals between cycles were 21 days instead of 28 days, bleomycin doses were reduced, small doses of prednisone were given orally, and the interval before RT was prolonged. RESULTS Clinical response was complete in 96% of patients who were treated with VBM plus EF-RT and in 94% of patients who were treated with VbMp plus IF-RT. Recurrence rates were nearly identical (12% and 11%, respectively) over necessarily different follow-up (91 months and 33 months, respectively). Hematologic toxicity was tolerable in both trials, and pulmonary side effects were moderate in the first trial and negligible in the second. On the whole, treatment was tolerated better when RT followed chemotherapy. CONCLUSIONS The VBM regimen was confirmed to be effective in patients with early-stage Hodgkin lymphoma. Administration of all cycles before RT improved tolerance; pulmonary toxicity probably is mitigated further by reduced bleomycin doses, mild prednisone therapy, and a more prolonged resting interval before RT. A slightly higher recurrence rate was expectable in the VBM plus IF-RT trial despite the actual intensification of vinblastine and methotrexate. Cancer 2003. © 2003 American Cancer Society. [source] Outcomes of autoconjunctival grafting for primary pterygia when performed by consultant compared with trainee ophthalmologistsCLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 9 2006Jonathon J Farrah MBBS(Hons) Abstract Purpose:, To define rates of recurrence and surgical complications of primary pterygia excision with autoconjunctival grafting when the surgery is performed by consultant ophthalmologists compared with trainee ophthalmologists. Methods:, A total of 174 patients with primary pterygia treated by excision and autoconjunctival grafting were included for analysis. Patients were divided into two groups according to whether their surgery was performed by a consultant ophthalmologist (group A) or a trainee ophthalmologist (group B). Data were collected with respect to demographics, surgical complications and recurrence. Recurrence rates were analysed utilizing Fisher's exact test. Additionally, Kaplan,Meier survival curves for interval censored data were constructed. Surgical complications were analysed utilizing Fisher's exact test. Results:, The recurrence rate in group A was 6.8% and in group B was 19.4%. This difference was statistically significant (P = 0.05). The rate of surgical complication occurring in group A was 6.6% and in group B was 23.3% and this was also statistically significant (P = 0.005). No relationship was found between either patient age or the size of pterygium and recurrence or complications in either group A or group B. Conclusion:, Autoconjunctival grafting is regarded as the gold standard for preventing pterygium recurrence following excision. This study suggests that the experience of the surgeon can influence success rates and complications. There is a significant learning curve indicating the need to supervise trainee surgeons. [source] EVALUATION OF DYSPEPTIC SYMPTOMS AND ACID SUPPRESSIVE DRUG (ASD) CONSUMPTION IN SUCCESFULLY ERADI CATED AND HEALED DUODENAL ULCER (DU) PATIENTS; RESULTS OF A ONE YEAR PROSPECTIVE STUDYJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 12 2000Pecsi Gy To determine the upper abdominal symptoms, the use of ASD and the recurrence-rate of Helicobacter pylori in DU (Hp) patients one year after ulcer healing and successful HP eradication. Patient and methods: 37 endoscopically proven healed and successfully eradicated DU patients were successfully recruited in the study. All patients had active ulcer and showed HP positivity both by rapid urease test and histology 5 weeks before the enrollement endoscopy. The severity and character of dyspeptic symptoms and the use of ASD-s were checked by questionnaires at the start and one year after successful eradication therapy. NSAID users and reflux oesophagitis patients were excluded at inclusion. Eradication was performed by a one week LAC combination followed by 4 week ranitidine therapy. HP reinfection was controlled by C13 urea breath test at the 12 month visit. Results: 7 patients were lost for follow up by the end of the one year program. A together the data of 30 eligible patients (17 females, 13 males, mean age 49 years) were analyzed. The questionnaires represent the symptoms and ASD use of the whole year program. Only 12 out of 30 patients (40%) were permanently and completely symptoms free after the cessation of the short-term therapy. 16 patients (53.3%) had temporary and 2 patients (6.7%) had persistant symptom. About half of the patients (n=17) were taking absolutely no ASD during the follow up. The number of occasional and continuous ASD users were 7 (23.4%) and 6 (20%) respectively. HP reinfections occurred in one patient and no ulcer relaps was proven. Conclusions: 1. More than half of the patients had clinically relevant dyspeptic symptoms during the year after successful HP eradication and ulcer healing. 2. The majority of them required occasional or long term ASD therapy in this period. 3. Recurrences rate of HP was low. [source] Trichloroacetic Acid Matricectomy in the Treatment of Ingrowing ToenailsDERMATOLOGIC SURGERY, Issue 6 2009SU-HAN KIM MD BACKGROUND Ingrowing toenails can be treated with conservative therapy or surgery, but frequent relapse can be a problem in conservative therapy and surgical therapy without matricectomy. Thus, permanent nail ablation by partial matricectomy is now accepted as the treatment of choice. OBJECTIVE To evaluate the efficacy and safety of trichloroacetic acid (TCA) matricectomy in the treatment of ingrowing nail. MATERIALS AND METHODS Forty ingrowing toenail edges in 25 patients were enrolled. TCA matricectomy with 100% trichloroacetic acid after partial nail avulsion was performed. For a few weeks after surgery, postoperative complications such as pain, discharge, and infection were assessed. After a mean follow-up period of 22.9 months, recurrence rate and cosmetic outcomes were investigated to evaluate the effects of the surgery. RESULTS The wounds almost always healed within 2 weeks without prolonged exudative discharge. Pain was mild and transient. A case of secondary infection occurred. Recurrence was found in only two nails of one patient, and the success rate was 95%, with good cosmetic results. CONCLUSION TCA matricectomy showed a low recurrence rate with minimal side effects and was easy to perform in outpatient clinic. Therefore, it may be a good alternative treatment of ingrowing toenails. [source] Mohs Micrographic Surgery in the Treatment of Rare Aggressive Cutaneous Tumors: The Geisinger ExperienceDERMATOLOGIC SURGERY, Issue 3 2007CHADWICK JOHN THOMAS MD BACKGROUND Mohs micrographic surgery (MMS) offers high cure rates and maximum tissue preservation in the treatment of more common cutaneous malignancies, but its effectiveness in rare aggressive tumors is poorly defined. OBJECTIVE Evaluate the effectiveness of MMS in the treatment of six rare aggressive cutaneous malignancies as seen by Mohs surgeons working at a referral center. METHODS Retrospective chart review of 26,000 cases treated with MMS at the Geisinger Medical Center Department of Dermatology during a 16-year period with the following diagnoses: poorly differentiated squamous cell carcinoma (PDSCC), dermatofibrosarcoma protuberans (DFSP), microcystic adnexal carcinoma (MAC), extramammary Paget's disease (EMPD), Merkel cell carcinoma (MCC), and sebaceous carcinoma (SEB CA). Patient demographic data, tumor measurements, treatment characteristics, and marginal recurrence rates were compiled and evaluated. RESULTS The mean numbers of cases identified per year for each tumor type were as follows: PDSCC, 6.19; DFSP, 2.44; MAC, 1.63; and EMPD, 0.63. For PDSCC, 85 cases were available for follow-up with a local recurrence rate of 6% at a mean follow-up time of 45 months. For DFSP, there were 35 cases with no local recurrence at a mean follow-up of 39 months. For MAC, there were 25 cases with a local recurrence rate of 12% at a mean follow-up of 39 months. For EMPD, there were 10 cases with no local recurrences at a mean follow-up of 34 months. CONCLUSIONS Collectively, our data on PDSCC, DFSP, MAC, and EMPD, combined with other studies in the literature, show that MMS is the most effective therapy for these rare aggressive cutaneous malignancies. [source] Minimal-Scar Segmental Extraction of Lipomas: Study of 122 Consecutive ProceduresDERMATOLOGIC SURGERY, Issue 1 2005Rajiv Y. Chandawarkar MD Background Surgical extirpation of lipomas that occur in cosmetically conspicuous areas of the body leaves a visible scar that is usually disfiguring. Minimal-scar segmental extraction (MSE) employs a much smaller incision and extraction and is particularly useful in exposed parts of the body. It can be easily performed in an office setting. Objective The objective of this study was to evaluate the merits of MSE in clinical practice. Unlike other reports in the literature that describe, anecdotally, minimally invasive methods of lipoma removal, our study examined a new method by carefully measuring the results in a larger group of consecutive patients treated using this technique. Materials and Methods A retrospective study was performed using data from 91 consecutive patients with a total of 122 lipomas that were treated using MSE. MSE of lipomas consists of a small stab incision and blind dissection of the tumor followed by its extraction in a segmental fashion. This procedure involves small instrumentation, minimal dissection with preservation of contour, and complete removal of the lipoma, including substantial portions of the capsule. Clinical data, including complications, outcomes, and recurrence rates, were recorded. Results The procedure was well tolerated by patients, who were pleased with the results, particularly the small scar. The incidence of complications was 1.6% (n= 2) and consisted of hematoma (n= 1) and seroma (n= 1). The recurrence rate was 0.8% (n= 1). No long-term morbidity was noted. Conclusions The technical ease with which the MSE can be performed, coupled with a low recurrence rate, makes it a very cost-effective operation. The smaller postoperative scars, rapid healing, and low morbidity allow for better patient acceptance. We recognize the advantages and limitations of this procedure and encourage its use in selected patients. RAJIV Y. CHANDAWARKAR, MD, PEDRO RODRIGUEZ, MD, JOHN ROUSSALIS, MD, AND M.

[source] Surgical Treatment of Chronic Gluteal Hidradenitis Suppurativa: Reused Skin Graft TechniqueDERMATOLOGIC SURGERY, Issue 2 2003Hung-wen Kuo MD BACKGROUND The treatment of chronic lesions in hidradenitis suppurativa (HS) remains a challenge for dermatologists. In most cases, wide surgical excision of the affected skin reduces the recurrence rate to a minimum. Split-thickness skin grafts have usually been applied to resurface large postoperative defects. OBJECTIVE The aim of this study is to introduce an alternative method of skin grafting, called "reused" or "recycled" skin graft, for the reconstruction of the large skin defect with chronic gluteal HS. METHODS The study consisted of six patients (two females and four males) with gluteal HS. After a wide en bloc excision, the wound was immediately recovered with meshed-skin graft, made from the resected skin itself. Thus, the sacrifice of the skin donor is spared. The drum dermatome (Padgett-Hood) is suitable to take the split-skin graft from the resected skin of the affected buttock. The thickness of grafts was set between 12/1,000 and 20/1,000 inches, and all grafts were meshed with 1.5 times the expansion. The skin grafts were secured in place on the wound and a tie-over dressing was applied. RESULTS Postoperative complications were usually minor ones, such as hematoma, discharge, and small areas of graft skin necrosis (less than 1 cm2), although one patient developed a 3×4 cm2 graft necrosis and wound infection. The follow-up period after surgery ranged from 8 to 36 months. No patient experienced any functional disabilities or recurrence during follow-up years. CONCLUSION When the epidermal involvement remains mild to moderate, this reused skin graft technique is an alternative choice to resurface the surgical defect of gluteal HS. It is superior to the conventional procedure, which requires fresh skin donor site. [source] Atypical fibroxanthoma/malignant fibrous histiocytomaDERMATOLOGIC THERAPY, Issue 6 2008Steven Marcet ABSTRACT:, Atypical fibroxanthoma (AFX) is an unusual spindle cell tumor occurring on actinically damaged skin of the head and neck. Clinically, it is often confused with basal cell carcinoma, squamous cell carcinoma, or even melanoma. Although initially thought to be a diagnosis of exclusion histologically, newer immunostains have helped in the identification of AFX. Mohs micrographic surgery has been utilized for the treatment due to its tissue sparing ability along with lower recurrence rate. [source] HEMODYNAMIC MECHANISM OF ESOPHAGEAL VARICESDIGESTIVE ENDOSCOPY, Issue 1 2006Katsutoshi Obara We investigated the correlation between the collaterals around the esophagus and recurrence of esophageal varices in patients with portal hypertension who had undergone endoscopic injection sclerotherapy (EIS). In patients with portal hypertension, many types of collaterals around the esophagus were visualized by endoscopic ultrasonography (EUS). The collaterals outside the esophageal wall detected by EUS were divided into two groups according to the location of the veins: peri-esophageal collateral veins (peri-ECV) and para-esophageal collateral veins (para-ECV) Perforating veins are those that have penetrated the esophageal wall and have connected with either peri-ECV or para-ECV. We demonstrated that severe peri-ECV and large perforating veins play an important role in the development of esophageal varices in untreated patients with portal hypertension. The results of our investigation have shown that detection of peri-ECV and perforating veins by EUS and treatment of them by EIS appears to be important for the treatment of esophageal varices. The disappearance of peri-ECV by EIS is essential for reducing the recurrence rate of esophageal varices. To prevent variceal recurrence, a mucosal fibrosing method using argon plasma coagulation has been widely performed in Japan. If EUS abnormalities are associated with variceal recurrence, we recommend the use of the mucosal fibrosing method. In conclusion, the presence of severe peri-ECV and large perforating veins in the esophageal wall strongly correlate with the recurrence of esophageal varices in patients with portal hypertension. An understanding of these EUS abnormalities on the basis of hemodynamics around the esophagus is important for the management of esophageal varices in patients with portal hypertension. [source] Primary laparoscopic and open repair of paraesophageal hernias: a comparison of short-term outcomesDISEASES OF THE ESOPHAGUS, Issue 1 2008S. Karmali SUMMARY. The choice of the optimal surgical approach for repairing paraesophaeal hernias (PEH) is debated. Our objective is to evaluate the short-term outcomes of primary laparoscopic and open repairs of PEH performed in the Calgary Health Region. A retrospective review of all patients undergoing repair of PEH between October 1999 and February 2005 was performed. The outcome measures evaluated included intra-operative parameters and post-operative variables, mortality rates, recurrence rates and patient satisfaction. A total of 93 patients underwent either a laparoscopic (n = 46) or open (n = 47) primary PEH repair. The laparoscopic approach was associated with a longer mean operative time (3.1 ± 1.2 hours vs. 2.5 ± 0.7 hours, P = 0.005) but resulted in a shorter overall hospital stay (5 days [2,16 days]vs. 10 days [5,24 days]; P < 0.001), and fewer post-operative complications (10/46 [22%]vs. 25/47 [53%]P = 0.002). Although the follow-up was short (laparoscopic 16 months; open 18 months), a 9% recurrence rate was reported with both approaches. Patient satisfaction using the Gastroesophageal Disease Health-Related Quality Of Life questionnaire was similar in both groups (P = 0.861) with most patients reporting excellent outcomes (laparoscopic: 32/36 [89%]; open 27/35 [77%]). Our review suggests that the laparoscopic approach is safe with shorter hospital stay and recovery. Although early follow-up suggests that recurrence rates and patient satisfaction are similar, long-term follow-up is required to determine whether the laparoscopic approach will become the procedure of choice. [source] Status Epilepticus in Children with Epilepsy: Dutch Study of Epilepsy in ChildhoodEPILEPSIA, Issue 9 2007Hans Stroink Summary:,Purpose: To study course and outcome of epilepsy in children having had a status epilepticus (SE) as the presenting sign or after the diagnosis. Methods: A total of 494 children with newly diagnosed epilepsy, aged 1 month through 15 years, were followed prospectively for 5 years. Results: A total of 47 Children had SE. Forty-one of them had SE when epilepsy was diagnosed. For 32 (78%), SE was the first seizure. SE recurred in 13 out of 41 (32%). Terminal remission at 5 years (TR5) was not significantly worse for these 41 children: 31.7% had a TR5 <1 year versus 21.2% of 447 children without SE. They were not more often intractable. Five out of six children with first SE after diagnosis had a TR5 <1 year. Mortality was not significantly increased for children with SE. Independent factors associated with SE at presentation were remote symptomatic and cryptogenic etiology, and a history of febrile convulsions. Children with first SE after inclusion more often had symptomatic etiology. Conclusions: Although we find a trend for shorter TR5 in children with SE at presentation, outcome and mortality are not significantly worse. Etiology is an important factor for prognosis. Children with SE during the course of their epilepsy have a worse prognosis and a high recurrence rate of SE. This outcome is not due to the SE itself, but related to the etiology and type of epilepsy. The occurrence of SE is just an indicator of the severity of the disease. [source] Febrile Seizures: Treatment and PrognosisEPILEPSIA, Issue 1 2000Finn Ursin Knudsen Summary: Recent epidemiologic data indicate that the vast majority of children with febrile seizures have a normal long-term outcome. A precise knowledge of the short- and long-term outcome with or without treatment, and short- and long-term side effects is an important prerequisite for assessing the various treatment strategies. We focus on the impact of short-term or prophylactic treatment on the short- and long-term outcome of various types of febrile seizures. There is universal agreement that daily prophylaxis with antiepileptic agents should never be used routinely in simple febrile seizures, but only in highly selected cases, if at all. Intermittent diazepam (DZP) prophylaxis at times of fever may or may not reduce the recurrence rate, but it does not appear to improve the long-term outcome as compared with short-term seizure control. The treatment may be used to reduce the recurrence rate for a small arbitrarily defined group with multiple simple febrile seizures, complex febrile seizures, especially focal, prolonged or both, febrile status, and when parental anxiety is severe. However, there is no evidence that treatment of simple febrile seizures can prevent the rare cases of later epilepsy, and many children with complex febrile seizures have a benign long-term outcome, even without treatment. Many prefer a "wait and see" policy. An attractive alternative is to treat new febrile seizures with rectal DZP in solution at seizure onset, given by the parents at home to prevent febrile status. Newer, less well documented short-term strategies include nasal, oral, or rectal administration of other benzodiazepines. Short-term seizure control of febrile status and careful parental counseling are the two most important targets of treatment. [source] Efficacy of diagnostic upper node evaluation during (salvage) laryngectomy for supraglottic carcinomaHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 2 2009Ronald J. E. Pennings MD Abstract Background. The effectiveness of selective upper node dissection or inspection during laryngectomy for supraglottic squamous cell carcinoma was evaluated. These diagnostic procedures aimed to cause less morbidity than elective neck dissection in patients with a clinically N0 neck. Methods. In 93 patients, 166 clinically N0 necks (73 bilateral and 20 contralateral) were evaluated. Lymph nodes at levels II and III were inspected or dissected and directly sent in for frozen section histopathology. This way, occult neck metastases were identified and treated by neck dissection. Results. Occult neck metastases were identified in 19% of the examined necks (31/166). Regional recurrence rate in the postoperative N0 necks was 0%, and 10% in the postoperative N+ necks. Conclusions. Selective upper node dissection and inspection during laryngectomy reduced the need for an elective neck dissection with its morbidity in the clinically N0 neck. In addition, it selects the patients who need such extensive treatment. © 2008 Wiley Periodicals, Inc. Head Neck, 2009. [source] External auditory canal eccrine spiradenocarcinoma: A case report and review of literatureHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 6 2003Tanya K. Meyer MD Abstract Background. Eccrine spiradenocarcinoma is a rare dermal appendage carcinoma believed to arise from transformation of a long-standing benign spiradenoma. This tumor demonstrates highly malignant biologic behavior with a high recurrence rate, frequent lymph node metastases, and overall poor survival. Methods. We report the first case of eccrine spiradenocarcinoma arising in the external auditory canal. The management of this tumor, its histopathologic characteristics, and a review of literature are presented. Results. A literature review identified 17 cases of eccrine spiradenocarcinoma in the head and neck region. Local recurrence occurred in 58.8% of patients, with an average of 23 months from diagnosis. Lymph node metastasis occurred in 35.3%, with an average of 31 months from diagnosis. Other metastatic sites included skin, bone, and lung. Disease-specific mortality was 22.2%. Conclusions. Eccrine spiradenocarcinoma is an aggressive tumor with a poor prognosis. Primary treatment should include wide local excision with or without regional lymphadenectomy. Isolated successful treatments have been documented with adjuvant hormonal manipulation, chemotherapy, and radiation therapy. © 2003 Wiley Periodicals, Inc. Head Neck 25: 505,510, 2003 [source] Eletriptan in Migraine Patients Reporting Unsatisfactory Response to RizatriptanHEADACHE, Issue 7 2006Jerome Goldstein MD Objective.,The objective of this open-label study was to evaluate the efficacy of switching patients who had a previous unsatisfactory response to rizatriptan to eletriptan 40 mg. Background.,The characteristics of individual migraine patients can vary tremendously and can have a significant impact on treatment outcomes. In addition, clinical experience has demonstrated that the triptans are not identical or interchangeable and that patients who respond poorly or who are dissatisfied with one agent can derive benefit by being switched to another agent within the triptan class. Methods.,Patients were eligible if they met International Headache Society criteria for migraine, with a frequency of 1 to 6 migraine attacks per month, and had documented "unsatisfactory treatment response" to rizatriptan within the past year (54% on the melt formulation; 46% on tablets). Reasons for dissatisfaction with rizatriptan (>1 could be cited) included inadequate (84%) or slow onset (50%) of pain relief, high recurrence rate (69%), and lack of improvement in associated symptoms (60%). One hundred twenty-three patients were eligible for treatment. Patients were instructed to take eletriptan 40 mg as soon as they were certain that their headache was a migraine, regardless of level of pain severity (8% treated headaches that were mild). Results.,Headache response at 2 hours (first-attack data) was 64%. Absence of nausea (from baseline to 2 hours) increased from 50% to 78%, absence of photophobia from 30% to 72%, and absence of phonophobia from 39% to 77%. Functional response at 2 hours was 63%, with 41% of patients reporting normal functioning. Treatment with eletriptan 40 mg was associated with a 27% to 40% reduction in migraine attack-related functional impairment, as measured by the PQ-7. Recurrence rates were 36.6%. Overall, 72% of patients rated eletriptan as a "good-to-excellent" treatment, and 78% reported overall satisfaction with the degree of headache relief. Conclusion.,The results of this study suggest that eletriptan is an efficacious treatment option for patients who are dissatisfied with their response to rizatriptan. [source] Migraine Headache Recurrence: Relationship to Clinical, Pharmacological, and Pharmacokinetic Properties of TriptansHEADACHE, Issue 4 2003Gilles Géraud MD Background and Objectives.,Triptan use is associated with headache recurrence, and this has been cited as an important reason for patient dissatisfaction with the treatment. The mechanism by which recurrence occurs is not clear, and the incidence of recurrence varies with the triptan used. In order to explore the pharmacological and physiological interaction of triptans and migraine headache recurrence further, some specific clinical, pharmacological, and pharmacokinetic factors that might influence migraine recurrence were evaluated in a review of the major efficacy data for the drugs in the triptan class. These factors were 5-HT1B and 5-HT1D receptor activities, the pharmacokinetic elimination half-life of each triptan, and the clinical efficacy of each compound, determined by the proportion of patients with headache relief and the therapeutic gain over placebo. Methods.,Clinical data were derived from 31 triptan, placebo-controlled, major efficacy studies used in a previous meta-analysis. The mean recurrence rate, mean headache response, and therapeutic gain were calculated using the results from the individual clinical studies. Mean headache response and therapeutic gain were calculated at the time point used to define recurrence in each study. Data for binding affinity and potency were taken from a direct-comparison in vitro pharmacology study, and the elimination half-life quoted in the data sheet for each triptan was used. Rank correlation with recurrence rate was performed for each of the test parameters. Results.,Mean headache recurrence rates ranged from 17% for frovatriptan 2.5 mg to 40% for rizatriptan. Elimination half-life and recurrence were inversely correlated (r = ,1.0, P = .0016). There was also a significant inverse correlation between 5-HT1B receptor potency and recurrence (r = ,0.68, P = .034), but 5-HT1D receptor potency was not correlated with recurrence (r = ,0.20, P = .54). In addition, the binding affinities for the 5-HT1B and 5-HT1D receptors were not correlated to headache recurrence. Importantly, it also was demonstrated that initial clinical efficacy was not correlated to headache recurrence. The correlation coefficient for headache response was 0.18 (P = .53) and for therapeutic gain, ,0.11 (P = .71). Conclusion.,The incidence of migraine headache recurrence varies between drugs in the triptan class. Migraine recurrence does not appear to be related to initial clinical efficacy, but is influenced by the pharmacological and pharmacokinetic properties of the individual triptans. The triptans with longer half-lives and greater 5-HT1B receptor potency had the lowest rates of headache recurrence. [source] Mechanism of Action of Low Recurrence of Gastritis Caused by Helicobacter pylori with the Type II Urease B GeneHELICOBACTER, Issue 2 2004Md. Badruzzaman ABSTRACT Background., Low recurrence of gastritis is seen in patients infected with Helicobacter pylori carrying the type II urease B gene, compared with H. pylori carrying types I and III. The underlying mechanism has been studied in terms of the urease activity and interleukin (IL)-8 production capacity of different strains of H. pylori. Materials and Methods., Forty-five patients infected with different strains of H. pylori (type I; 15, type II; 15 and type III; 15) were enrolled in the study. H. pylori was isolated from gastric mucosa and cultured in the presence of urea at pH 5.5 to evaluate urease activity. The capacity of different strains of H. pylori to induce IL-8 mRNA and IL-8 from a human gastric cancer cell line and human peripheral blood mononuclear cells was evaluated. Results., The urease activity of type II H. pylori[523 ± 228 µg of ammonia/dl/108 colony-forming units (CFU)/ml] was significantly lower than that of type I (1355 ± 1369 µg of ammonia/dl/108 CFU/ml) and type III (1442 ± 2229 µg of ammonia/dl/108 CFU/ml) (p < .05). Gastric cancer cells cocultured with type II H. pylori produced lower levels of IL-8 mRNA compared with type I and type III H. pylori. The levels of IL-8 were also significantly lower in cultures induced by type II H. pylori compared with those induced by type I and type III H. pylori. Peripheral blood mononuclear cells also produced lower levels of IL-8 when cocultured with type II compared with type I H. pylori. Conclusions., These results indicate that both the lower level of urease activity and the low IL-8-inducing capacity of type II H. pylori might underlie the lower recurrence rate of gastritis caused by type II H. pylori.
