Treatment of achalasia: botulinum toxin injection vs. pneumatic balloon dilation. A prospective study with long-term follow-Up.

BACKGROUND AND STUDY AIMS: In patients with achalasia, intrasphincteric injection of botulinum toxin (BTX) has been suggested as an alternative regimen to balloon dilation and has been shown to be superior to placebo injection. The aim of the present study was to test the effectiveness, the long-term outcome and the cumulative costs of BTX injection in consecutive patients with symptomatic achalasia in comparison with pneumatic balloon dilation. PATIENTS AND METHODS: 37 patients, who presented with symptomatic achalasia between January 1994 and December 1996 were treated with either BTX injection (n = 23) or pneumatic dilation (n = 14). Patients with short-term or long-term symptomatic failures of the initial procedure were treated again, either with the same or with the alternative method, depending on the initial response and on the patient's wish. Symptoms were assessed using a global symptom score (0 - 10) which was evaluated before treatment and 1 week, 1 month and then every 6 months after the treatment. In addition, body weight and recurrence of symptoms were noted and manometry was carried out before and after treatment. The patients were regularly contacted for the long-term follow-up. RESULTS: There were significant improvements in the global symptom scores of all patients treated, in both the BTX injection group (before 8.2 +/- 1.3, after 3.0 +/- 1.6) and the dilation group (before 8.3 +/- 1.1, after 2.3 +/- 1.9). There was also a significant decrease of lower esophageal sphincter pressure after treatment in the BTX group and the dilation group. There were no significant differences with regard to overall treatment failure and long-term outcome between patients who had or had not received previous treatment. No major complications were encountered in either group. An actuarial analysis over 48 months comparing patients receiving BTX injection or balloon dilation demonstrated that after 12 months neither therapy was significantly superior. After 24 months a single pneumatic dilation was superior to a single BTX injection, and after 48 months all patients treated by BTX injection had experienced a symptomatic relapse. In contrast, 35 % of all patients treated by dilation and 45 % of patients treated successfully by dilation were still symptom-free in an intention-to-treat analysis after 48 months. When the overall costs of treatment and further treatment after recurrence were compared, dilation and BTX injection showed a similar cost-effectiveness (costs per symptom-free day) after 48 months. CONCLUSIONS: BTX injection, which can be performed in an outpatient setting, is as safe and cost-effective as balloon dilation in symptomatic achalasia. Taking into account the lower long-term efficacy of BTX injection therapy, however, it is an alternative only in a minority of older or high-risk patients.

Treatment of bone and soft tissue sarcomas of the hand and wrist.

We studied 13 consecutive patients with bone and soft tissue sarcomas of the hand and wrist. Chondrosarcoma, Ewing's sarcoma, synovial sarcoma and epithelioid sarcoma were the most frequent histological diagnoses. Limb-sparing surgery was performed in ten patients but eventually three patients required an amputation. Surgical margins were wide in nine patients and marginal in four. Adjuvant therapy for nine patients consisted of chemotherapy in five and chemotherapy with radiation in four. Local recurrence occurred in two patients with epithelioid sarcoma. There was no significant relationship between surgical margin and local recurrence. Distant metastasis occurred in four patients. The 5-year survival rate was 66%. The mean functional score was 87%. Our study indicates that treatment consisting of resection of these tumours with either a wide margin or a marginal margin followed by adjuvant radiation appeared to be safe and resulted in an acceptable degree of limb function except in the patients with epithelioid sarcoma.

The PROSTALAC functional spacer in two-stage revision for infected knee replacements. Prosthesis of antibiotic-loaded acrylic cement.

The PROSTALAC functional spacer is made of antibiotic-loaded acrylic cement but has a small metal-on-polythene articular surface. We have used it as an interim spacer in two-stage exchange arthroplasty for infected total knee replacement. PROSTALAC allows continuous rehabilitation between stages as it maintains good alignment and stability of the knee and a reasonable range of movement. It also helps to maintain the soft-tissue planes, which facilitates the second-stage procedure. We reviewed 45 consecutive patients, treated over a period of nine years. The mean follow-up was for 48 months (20 to 112). At final review, there was no evidence of infection in 41 patients (91%); only one had a recurrent infection with the same organism. There was improvement in the Hospital for Special Surgery knee score between stages and at final review. The range of movement was maintained between stages. Complications were primarily related to the extensor mechanism and stability of the knee between stages. Both of these problems decreased with refinement of the design of the implant. The rate of cure of the infection in our patients was similar to that using other methods. Movement of the knee does not appear to hinder control of infection.

Preliminary analysis of a newly proposed prognostic scoring system (SLiDe score) for hepatocellular carcinoma.

BACKGROUND: The long-term prognosis of hepatocellular carcinoma (HCC) remains poor and the prediction of survival is often difficult because of the limited liver function and frequent recurrence of HCC in most patients. Therefore, a prognostic classification of HCC should account for both tumor-related variables and liver function. METHODS: The value of reported prognostic factors for HCC was assessed and a new prognostic classification was established called the 'SLiDe' scoring system (S, stage; Li, liver damage; De, des-gamma-carboxy prothrombin) using 'stage' and 'liver damage' of the recently revised 4th edition of the Japanese staging system edited by the Liver Cancer Study Group of Japan, and the serum level of des-gamma-carboxy prothrombin (DCP) in 177 patients with HCC. RESULTS: Univariate analysis identified Child-Pugh stage, liver damage, tumor morphology, portal vein thrombosis, stage, serum level of alpha-fetoprotein (AFP), serum level of DCP, and initial treatment as significant prognostic factors. Of these, liver damage, stage, and serum level of DCP remained independent predictive factors of survival after multivariate prognostic analysis using the proportional hazards regression model. Therefore, a new prognostic scoring system (SLiDe scoring system) was derived that assigned a linear score (0/1/2/3) to these three covariates. This SLiDe scoring system was statistically a better model for predicting outcome in the present study population than the Cancer of the Liver Italian Program (CLIP) and the Japan Integrated Staging (JIS) scoring systems, as judged by the Akaike Information Criteria. CONCLUSION: The SLiDe scoring system is useful for the assessment of the prognosis of patients with HCC as long as the Japanese staging system is used, although this uses parameters such as the indocyanine green retention test and DCP, which are not examined routinely in every part of the world. Therefore, the proposed classification should be further validated in other large study populations.

Integrated expression profiling of trophoblast cell-surface antigen 2 (TROP2), folate receptor alpha (FRα), and human epidermal growth factor receptor 2 (HER2) in endometrial Cancer across molecular classes, genomic alterations, and histologic subtypes.

OBJECTIVE: Antibody-drug conjugates (ADCs) are expanding treatment options in endometrial carcinoma, but the distribution of actionable surface targets across histologic, molecular, and genomic subgroups remains incompletely defined. METHODS: This single-institution retrospective tissue microarray (TMA) study included 312 endometrial carcinomas: 158 endometrioid and 154 serous tumors. Trophoblast cell-surface antigen 2 (TROP2) was quantified by histochemical score (H-score); human epidermal growth factor receptor 2 (HER2) was assessed using endometrial carcinoma-specific and gastric/DESTINY-PanTumor02 criteria; and folate receptor alpha (FRα) positivity was defined as ≥75% viable tumor cells with ≥2+ membranous staining. Molecular class was assigned using a hierarchical DNA polymerase epsilon (POLE)-mutant, microsatellite instability/mismatch repair-deficient (MSI/MMRd), p53-abnormal, and no specific molecular profile (NSMP) classifier. Tumor mutational burden (TMB) and recurrent genomic alterations were analyzed in relation to biomarker expression. RESULTS: TROP2 was broadly expressed, with median H-scores of 280 in endometrioid and 200 in serous carcinomas. HER2 gastric-score 2+/3+ expression and FRα positivity were enriched in serous versus endometrioid carcinoma (22.5% vs 8.9% and 20.1% vs 4.4%), restricted to FIGO grade 3 tumors, and concentrated in p53-abnormal disease. FRα positivity was absent in POLE-mutant and MSI/MMRd tumors. HER2 2+/3+ expression correlated with erb-b2 receptor tyrosine kinase 2 (ERBB2) alterations, whereas FRα-positive tumors were enriched for TP53 alterations and showed lower frequencies of ARID1A and PTEN alterations. Triple-negative TROP2/HER2/FRα tumors were uncommon (6/308, 1.9%). CONCLUSIONS: TROP2 is broadly expressed in endometrial carcinoma, whereas HER2 and FRα define a more restricted high-grade, serous/serous-like, p53-abnormal compartment, supporting biomarker-informed ADC development.

Five-year experience with combined operative and radiotherapeutic treatment of recurrent gynecologic tumors infiltrating the pelvic wall.

BACKGROUND: Whereas 25 to 50% of selected patients with gynecologic tumors who relapse centrally in an irradiated pelvis can be salvaged by exenteration, postirradiation recurrence infiltrating the pelvic side wall generally has been fatal. We have designed the combined operative and radiotherapeutic treatment (CORT) procedure for the treatment of postirradiation recurrence infiltrating the pelvic wall and developed several new techniques for its realization. The aim of the surgery is as follows: (1) total resection of the tumor with only a microscopic margin (R1) at the pelvic wall, preserving the bony pelvis and the neurovascular support of the leg; (2) modulation of the therapeutic index for a second high-dose irradiation of the pelvic wall by transferring autologous tissue from the abdomen or the thigh, and (3) reconstruction of pelvic organ functions lost due to tumor resection. The tumor bed is irradiated postoperatively with brachytherapy through transcutaneous guide tubes implanted at the pelvic wall. METHODS: Between April 1989 and December 1994, we treated 48 patients with postirradiation recurrent or persistent gynecologic malignancies infiltrating the pelvic wall with CORT and followed them prospectively with the following endpoints: tumor control, survival, complications, and quality of life. RESULTS: At a median follow-up of 33 months (range, 3-71 months), the 5-year survival probability calculated with the Kaplan-Meier method was 44%. The overall local control rate was 68%, and 85% in the last 25 patients in the series. The censored severe complication rate at 5 years was 33%. No patient died as a consequence of the treatment. Quality of life was self-assessed with a validated questionnaire by 15 patients without evidence of disease, and was rated with a total of 74% of the maximum score points. Age of the patient, state of resection at the pelvic wall (R1 vs. R2), and recurrent tumor size independently influenced tumor progression after CORT in this series. CONCLUSIONS: CORT appears to be a feasible, innovative treatment with long term survival potential and acceptable quality of life for selected patients with postirradiation gynecologic tumor recurrence infiltrating the pelvic wall. R1 resection of the tumor at the pelvic wall is mandatory; however, the reconstruction options within the pelvis are limited.

Association of lipoprotein-associated phospholipase A2 with recurrence risk and its predictive value in large artery atherosclerotic stroke.

OBJECTIVE: To investigate the association of lipoprotein-associated phospholipase A2 (Lp-PLA2) with large artery atherosclerotic (LAA) stroke and its predictive value for recurrence. METHODS: We consecutively enrolled 412 acute LAA stroke patients. Using a cutoff of 200 ng/mL, patients were divided into high and low Lp-PLA2 groups, and into recurrence and non‑recurrence groups based on 1‑year follow‑up. Baseline characteristics, lipid profiles, National Institutes of Health Stroke Scale (NIHSS) scores, and vascular stenosis degree were compared. Binary logistic regression and Receiver Operating Characteristic (ROC) analysis were used to identify independent risk factors and evaluate predictive value. RESULTS: The high Lp-PLA2 group had significantly higher low-density lipoprotein cholesterol (LDL-C), small dense low-density lipoprotein cholesterol (sdLDL-C), prevalence of severe stenosis (≥70%), and proportion of NIHSS > 15 (all P < 0.05). The recurrence group showed elevated Lp-PLA2, higher LDL‑C and sdLDL-C, more severe neurological deficits, and more severe stenosis (all P < 0.001). Multivariable regression identified elevated Lp-PLA2 (per 10 ng/mL: OR = 1.139, 95% CI: 1.089-1.191), moderate (OR = 3.145) and severe (OR = 11.663) neurological deficits, and severe stenosis (OR = 9.390) as independent risk factors for recurrence (all P < 0.05). The Area Under the Curve (AUC) of Lp-PLA2 was 0.75 (95% CI: 0.69-0.82), with an optimal cutoff of 208.95 ng/mL. CONCLUSION: Elevated Lp-PLA2 is associated with adverse lipid profiles, more severe neurological deficits, and greater vascular stenosis in LAA stroke patients, and independently predicts 1‑year recurrence. Lp-PLA2 shows moderate predictive value, supporting its potential for risk stratification.

Visual function more than 10 years after optic neuritis: experience of the optic neuritis treatment trial.

PURPOSE: To assess visual function more than 10 years after an episode of optic neuritis in patients enrolled in the Optic Neuritis Treatment Trial. DESIGN: Longitudinal follow-up of a randomized clinical trial. METHODS: Vision testing included measures of visual acuity, contrast sensitivity, and visual field. Quality of life was assessed with the National Eye Institute Visual Function Questionnaire. RESULTS: Examinations were completed on 319 patients. In most patients, visual function test results in the eyes that experienced optic neuritis at study entry ("affected eyes") were normal or only slightly abnormal after 9.9 to 13.7 years. Visual acuity in the affected eyes was >or=20/20 in 74%, 20/25 to 20/40 in 18%, <20/40 to 20/200 in 5%, and <20/200 in 3%. On average, visual function was worse in patients with multiple sclerosis (MS) than in those without MS. Recurrent optic neuritis in either eye occurred in 35% of patients. Such attacks were more frequent in patients with MS (P <.001). The National Eye Institute Visual Function Questionnaire scores were lower when visual acuity was abnormal and when MS was present. CONCLUSIONS: Most patients retained good to excellent vision more than 10 years after an attack of optic neuritis. Recurrences were more frequent in patients with MS.

Overexpression of p53 protein in squamous cell carcinoma of buccal mucosa and tongue in Taiwan: an immunohistochemical and clinicopathological study.

Sixty squamous cell carcinomas of tongue and buccal mucosa were examined for expression of p53 protein by using an immunohistochemical technique improved by an antigen retrieval method. Twenty-seven (45%) tumors demonstrated strongly positive staining. Thirteen of p53-positive tumors (48%) also exhibited overexpression of p53 in immediately adjoining hyperplastic or pre-malignant epithelium. All 22 metastatic lymph nodes and 18 local recurrent lesions (except two) had an identical p53 immunophenotype to their corresponding primary sites. Mitotic indices were significantly higher in p53-positive tumors (P < 0.01); however, no association of PCNA scores with p53 expression was found (P > 0.1). There was no correlation between p53 overexpression and tumor grade, size and staging, vascular invasion, lymph node metastasis, and early local recurrence. Overexpression of p53 was found to be relatively higher, although not statistically significant, in nonsmokers than in heavy smokers (66.7% vs. 42.9%), and in nonbetel-quid chewers than in heavy chewers (62.5% vs. 34.2%). These data are consistent with the hypothesis that inactivation of p53 protein may occur in the early phases of oral tumorigenesis. It may not be a useful prognostic marker but could possibly be used for risk assessment and surveillance of local recurrence.

Identifying depression in the first postpartum year: guidelines for office-based screening and referral.

BACKGROUND: Some 10-15% of women experience postpartum-onset major depression (PPMD). The objective of this study was to determine if the Edinburgh Postnatal Depression Scale (EPDS) is an effective screen for major depression (MD) prospectively. The outcome of the study was identification of a recurrence of major depression in the first year postpartum by a clinical interview and the EPDS. We had the unique opportunity to examine the relationship between EPDS scores and PPMD. METHODS: Participants were pregnant women who had experienced an episode of previous PPMD but were well during their index pregnancy. This study was part of a double-blind, randomized clinical trial in which new mothers received nortriptyline or placebo within 24 h following delivery for prevention of PPMD. Recurrence of depression was established according to Research Diagnostic Criteria. Participants completed the EPDS weekly through 20 weeks postpartum and into a 1-year follow-up phase. RESULTS: Out of 50 women, 13 experienced recurrence of MD in the first 20 weeks postpartum with a total of 20 out of 50 recurring in the first year. The EPDS score of >9 at week 4 postpartum identified 60% of women who nurtured in the first 20 weeks and 80% who recurred in the first postpartum year. LIMITATIONS: The study population included only women who had a previous episode of postpartum depression. The generalizability to all women is limited. CONCLUSIONS: The EPDS is an effective depression screen for women who had a previous episode of PPMD. Clinical guidelines are provided for use of the EPDS to identify MD in the first postpartum year in primary care settings.

The prognostic significance of p34cdc2 and cyclin D1 protein expression in prostate adenocarcinoma.

BACKGROUND: Cyclin-dependent kinases (CDK) and cyclins constitute the subunits of the maturation-promoting factor that controls the process of cell division. High levels of these proteins have been reported in human malignancies of the stomach, colon, breast, and lung, and have been implicated in aberrant cell division and dysregulated tumor growth. METHODS: p34cdc2 CDK and cyclin D1 (D1) protein expression were evaluated in 140 radical prostatectomy specimens harboring adenocarcinoma (PAC), using the respective monoclonal antibodies on archival tissue sections. In each case, slides stained with hematoxylin and eosin were examined for evaluation of Gleason's grade and pathologic stage. The DNA content of the tumors was determined by the Feulgen method with the CAS200 Image Analyzer (Cell Analysis Systems, Lombard, IL). Nuclear immunoreactivity for the two proteins was semiquantitatively scored, and results were correlated with Gleason's grade, stage, ploidy, metastatic status, and disease recurrence after radical prostatectomy. RESULTS: p34cdc2 was expressed in 84 of 140 PACs (60%) and correlated with high Gleason's grade (P = 0.0001), advanced pathologic stage (P = 0.01), nondiploid DNA content (P = 0.0001), and metastases (P = 0.04). On multivariate analysis using the Cox proportional hazards model, p34cdc2 immunoreactivity (P = 0.0001) and high Gleason's grade (P = 0.01) each independently predicted disease recurrence. When tumors were of low Gleason's grade and lacked p34cdc2 expression, 4 of 39 PACs (10%) recurred, as compared with 18 of 47 (38%) that recurred when tumors were of high Gleason's grade and expressed p34cdc2 protein. D1 was positive in 31 of 140 PACs (22%) and showed a trend (P = 0.07) of high Gleason's grade, but it did not reach statistical significance with any of the prognostic variables. In the majority of PACs expressing both p34cdc2 and D1 proteins, the adjacent benign prostate acini showed focal, scattered nuclear positivity of the basal and secretory epithelial cells. CONCLUSIONS: p34cdc2 is expressed in a majority of PACs and correlates with high Gleason's grade, advanced pathologic stage, nondiploid DNA content, and metastases. On multivariate analyses high Gleason's grade and p34cdc2 immunoreactivity predict disease recurrence independently of the pathologic stage. Thus, p34cdc2 appears to play a critical role in the evolution, proliferation, and spread of PACs and may be of prognostic value when applied to initial prostate tissue samples taken by needle biopsy.

Intracarpal steroid injection is safe and effective for short-term management of carpal tunnel syndrome.

A double-blinded placebo-controlled trial was performed to evaluate the use of steroid injections beneath the transverse carpal ligament in the treatment of carpal tunnel syndrome (CTS) refractory to nonsurgical therapy. Forty-three patients received 6 mg betamethasone and lidocaine and 38 patients received 1 ml saline placebo and lidocaine. The primary outcome measure was satisfaction with symptom relief. Thirty patients (70%) in the steroid-treated group were satisfied or highly satisfied compared with 13 (34%) of placebo-treated patients (P < 0.001). Patients receiving steroids also showed significant improvement in median nerve conduction parameters and scores on validated symptom/function questionnaires. Forty-six patients were treated with serial injections for recurrent CTS symptoms. After 18 months, 17 patients reported adequate symptom relief with steroid injection, and 18 patients with unsatisfactory symptom relief were referred for carpal tunnel release surgery. We conclude that although steroid injections are safe and effective for temporary relief of CTS, most patients will eventually require surgery for long-term control of their symptoms.

Posterior dislocation of the shoulder: recommendations for a classification.

Posterior dislocation of the should is rare, constituting only 2.1% of all shoulder dislocations. The mechanisms of injury may be due to direct or indirect forces, and constitutional predisposing factors also play a role. Anatomically, 97.5% of dislocations are subacromial. Three hundred articles published in the international literature concerning posterior shoulder dislocation and subluxation were reviewed and a classification determined by the underlying aetiology was developed. On this basis dislocations and subluxations may be traumatic or atraumatic, primary and recurrent; recurrent cases of voluntary dislocation are considered separately. In addition, a follow-up assessment score weighted towards stability of the shoulder after treatment is detailed.

Improvement of hybrid yield by advanced backcross QTL analysis in elite maize.

We applied an advanced backcross breeding strategy to identify quantitative trait loci (QTLs) of agronomic importance in a cross between two elite inbreds of maize, RD6502 (Mo17-type recurrent parent) and RD3013 (Iodent donor parent). Two hundred and four BC(2) families were scored at 106 SSR, 15 AFLP, and 38 Heartbreaker (MITE) loci. BC(2) testcrosses (TC) with B73 were phenotyped at six locations in the Midwest and N.Y. We detected four grain yield, six grain moisture, and three plant height QTLs at which the RD3013 allele had a favorable effect ( p < 0.05). All four yield QTLs were selected as target introgressions in the development of BC(3)TC families. As predicted by BC(2)TC analysis, BC(3)TC entries containing introgressions at yld3.1 and yld10.1 significantly outperformed non-carrier entries by 11.1% (15.6 bu/A at one location) and 6.7% (7.1 bu/A averaged across two locations), respectively, in replicated Midwestern trials ( p < 0.05). Detection of yld10.1 effects in the BC(2)TC by spatial analysis (i.e., incomplete block, response surface, autoregressive, moving average or autoregressive moving average), but not by conventional single point analysis or interval mapping, indicated the utility of local environmental control for QTL mapping in unreplicated maize progeny. This work demonstrated that the advanced backcross QTL method can be applied to identify and manipulate useful QTLs in heterotic inbreds of elite maize. Genetic gains by this approach can be coupled with the maintenance and selection of favorable epistatic gene complexes by traditional hybrid breeding for maize improvement.

[Systemic lupus erythematosus and antiphospholipid syndrome].

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder characterized by the synthesis of antinuclear antibodies. Nucleosomes- the disc-like structural units of chromatin, composed of histones and DNA-are the primary antigenic structure that induces the formation of complement-activating antigen-antibody complexes in basement membranes. The autoreactivity in SLE has been elucidated in drug-induced SLE: hypomethylation of DNA leads to overexpression of integrin CD11a/ CD18, increased binding of T-cells to macrophages and B-cells, a higher rate of apoptosis of macrophages, and elevated B-cell activity with consecutive production of autoantibodies. Disturbances of apoptosis (e.g. mutation of Fas gene) are relevant also in non-drug-induced SLE. The morphologic diagnosis-by light microscopy, immunohistology and electron microscopy-of skin and renal biopsies can confirm the diagnosis and help in prognostic assessment as well as therapeutic decisions in SLE. The value of the morphologic diagnosis in SLE is enhanced by reporting semiquantitative scores of disease activity and chronicity. The antiphospholipid syndrome (APS) is characterized by thrombosis, thrombocytopenia, recurrent fetal loss and antiphospholipid antibodies. APS associated with SLE or other systemic autoimmune diseases has been termed secondary APS. Antibodies in APS are directed against phospholipids and phospholipid-protein complexes. One of these proteins is beta 2-glycoprotein 1. An important mechanism of the increased rate of thrombosis in APS is probably the inhibition of the protein C-catalyzed inactivation of clotting factors V and VIII. Venous thrombosis with recurrent pulmonary emboli and arterial thrombi in brain, heart and kidney (thrombotic microangiopathy) can lead to divergent clinical manifestations in APS.

[Treatment anxiety in oral and maxillofacial surgery].

BACKGROUND: Oral and maxillofacial operations are stressful treatment situations for patients. Specific data on this phenomenon were acquired through a multicenter study. MATERIAL AND METHODS: A 10-page questionnaire was answered by 600 oral and maxillofacial patients before individual treatment. Control groups consisted of 800 surgical, dental, internal medicine and general practitioner patients. 26 practices and hospital departments in 11 German cities were involved in the study. RESULTS: Both subjective anxiety assessment by patients and objective measurement (State Trait Anxiety Inventory; STAI) indicated a high level of treatment anxiety for oral and maxillofacial treatment. STAI scores for OMFS patients were significantly higher than in control groups. Especially female patients, patients treated under local anaesthesia and out-department patients showed high anxiety scores. Treatment experience in oral and maxillofacial surgery does not modify anxiety in case of recurrent treatment. CONCLUSION: Managing perioperative anxiety today is still a major challenge in oral and maxillofacial surgery. Irrespective of technical and pharmacological advances further studies on this topic and the development and establishing of stress-reducing and anxiolytic perioperative techniques are of considerable importance.

Development of a multicenter peripheral arterial interventional database: the PVD-QI2.

BACKGROUND: The number of peripheral vascular intervention (PVI) procedures performed is steadily increasing in the United States. PVD-QI 2 is a prospective, multicenter observational study designed to improve the quality of care for patients undergoing PVI and to better understand the effectiveness and appropriateness of PVI in improving outcomes of peripheral arterial disease. The registry aims to elucidate which comorbid conditions and procedure-related variables are associated with beneficial or adverse outcomes after vascular interventions. METHODS: Five centers are currently prospectively collecting data on consecutive PVIs performed at their institutions and will include patients with both claudication and critical limb ischemia. A common data collection form and a standard set of definitions were developed during several planning meetings. Information on patient demographics, clinical history, comorbid conditions, treatment approaches, and in hospital outcomes are being collected. Patients will be followed up at 30 days, 6 months, and 1 year after each procedure to identify recurrent vascular events, medication use, lifestyle modifications (regular exercise, dietary modification), self-reported walking scores, and mortality. Data validity will be assured through review of data form accuracy by a trained nurse, by automatic database diagnostic routines, and by site visits that include review of angiography suite logs and randomly selected charts. CONCLUSIONS: The development of a quality-controlled PVI registry requires the commitment and collaboration of clinician-investigators and hospital systems devoted to understanding factors that contribute to quality outcomes. Central to achievement of this goal is the creation of a careful diagnostic and data quality assessment system. This registry will provide important clinical insights into patient demographic and clinical characteristics, procedural characteristics, and current practice patterns that foster or impede achievement of long-term quality-based clinical outcomes for patients with peripheral arterial disease.

A prognostic index (bladder prognostic index) for bilharzial-related invasive bladder cancer.

PURPOSE: Bladder cancer is still the most common solid tumor among adult males in Egypt because of the prevalence of bilharzial infestation, especially in the countryside. In this prospective study, we have recorded the prognostic factors for 180 patients with invasive bladder cancer for whom standard radical cystectomy had been performed to develop a prognostic index (bladder prognostic index) that defines high risk patients who are more vulnerable to disease relapse after surgery and who may benefit from additional therapy. PATIENTS AND METHODS: The study was performed between January 1997 and December 1999, in which 180 patients with histopathologically proved invasive bladder cancer associated with bilharziasis underwent radical cystectomy or anterior pelvic exenteration. After surgery, patients were regularly followed for a minimum of 2 years. RESULTS: Our patients included 141 males and 39 females. Squamous cell carcinoma was the most common type (53.3%), and most of the tumors were grade II (61.1%). A total of 173 patients had their tumors operable, while 7 were inoperable. We had 5 (2.8%) operative related mortalities. At 5 years postoperatively, free and overall survival rates for the whole group of patients were 31.44%+/-5.9% and 32.5%+/-6.8%, respectively. Tumor pathologic stage, grade, and nodal affection were the only significant factors with impact on survival (P=0.008, 0.051, and 0.004, respectively). These 3 prognostic indexes were used to design a model to predict an individual patient's risk factor for recurrence. Patients were then assigned to one of the 4 risk groups according to the score achieved in this prognostic index (0=low risk, 1=intermediate risk, and 2 or 3=higher risk). These 4 risk groups had distinctly different rates of disease-free survival, i.e., 91.7%, 53%, 13%, and 7% for low, intermediate, and higher risk groups, respectively. CONCLUSION: Although this prognostic index appears to be of a significant clinical relevance, it needs to be more validated on a larger number of patients, and it could be a surrogate variable for biologic factors responsible for the heterogeneity of bladder cancer.
