A risk score system for identification of patients with upper-GI bleeding suitable for outpatient management.

BACKGROUND: The aim of this study was to develop a risk score system for identification of patients with upper-GI hemorrhage who are suitable for outpatient management. METHODS: From a prospective cohort of 983 consecutive patients with upper-GI hemorrhage not associated with portal hypertension, 581 cases that did not meet pre-established criteria for admission were selected, and a logistic regression analysis was performed to identify factors associated with two adverse outcomes: recurrent bleeding and/or the need for emergency surgery. The risk score system was developed by using the beta coefficients of the logistic model, and its performance was evaluated. The results of this model were combined with pre-established criteria for admission to build a simplified scoring system for identification of patients who can be managed safely on an outpatient basis. RESULTS: Chronic alcoholism, active malignancy, prior upper digestive tract surgery, wasting syndrome, hemodynamic compromise, duodenal ulcer as the cause of upper-GI hemorrhage, and hemorrhage of unknown cause were independently associated with a greater risk of unfavorable outcomes in the group that did not meet pre-established criteria for admission. The logistic model showed a high capacity for discrimination (C statistic: 0.87) and good calibration (p value for Hosmer-Lemeshow goodness-of-fit test, 0.62), with a sensitivity of 100% and specificity of 64%. The simplified score had a sensitivity of 100% and specificity of 29% for adverse outcomes, and sensitivity of 78% and specificity of 38% for mortality. CONCLUSIONS: The score system developed in this study may be helpful in deciding between hospitalization and outpatient management for patients with upper-GI hemorrhage, but it remains to be validated in patient groups other than those used for its development.

Teratomas of the central nervous system: treatment considerations based on 34 cases.

OBJECT: The optimum clinical management of central nervous system (CNS) teratomas, particularly postsurgical adjuvant therapy, is still unclear, partly as a result of the tumors' low incidence. In this study the authors analyze 34 cases of CNS teratomas so that they may adequately indicate management of these lesions. METHODS: The median age of the 34 patients was 13 years. Twenty-seven patients treated between 1970 and 1991 were retrospectively reviewed. Four of these 27 patients died as a result of radical surgery; each of them had a teratoma involving the hypothalamus. After initial treatment, which included radiation therapy, 20 patients (48%) had died. In all seven cases of mature teratomas there was no recurrence. In two cases of immature teratomas in which there was complete surgical resection there was recurrence; however, salvage therapies were effective. Seven of eight patients with highly malignant teratomas died; for these patients salvage therapies, including repeated radiation and chemotherapy, failed. Seven patients who presented with CNS teratomas between 1992 and 1996 received adjuvant chemotherapy and radiation therapy according to a prospective study protocol. All seven patients were free from recurrence with a 70 to 100% Karnofsky Performance Scale score at a median follow-up period of 41 months. Patients with CNS teratomas rarely responded completely to chemotherapy or radiation therapy; an effective adjuvant therapy produced a partial response at best. CONCLUSIONS: Because teratomas show various responses to adjuvant therapy, a misdiagnosis of their histological subtype will lead to inadequate therapy. A diverse therapeutic protocol based on histological diagnosis is necessary to plan appropriate management. Treatment recommendations are discussed in detail in the article.

Thermal medial retinaculum shrinkage and lateral release for the treatment of recurrent patellar instability.

PURPOSE: To study a technique of medial retinacular thermal shrinkage and evaluate the clinical effectiveness of this technique. TYPE OF STUDY: Nonrandomized prospective case series. METHODS: A consecutive series of patients with recurrent patellar instability treated with arthroscopic lateral release and medial thermal retinaculum shrinkage using a monopolar radiofrequency probe was assessed subjectively by visual analog scale and both preoperatively and postoperatively by physical examination and Lysholm and Fulkerson knee scores. RESULTS: We evaluated 53 knees with an average follow-up of 53 months (range, 24 to 88 months). The mean Lysholm and Fulkerson scores improved from 45 and 41 to 81 and 82, respectively. Subjectively, 48 of 53 knees (90%) were reported as excellent or good. The average visual analog scale score was 8 out of 10. Five patients failed because of recurrent dislocation (9% recurrence). Additional stabilization procedures were performed in 4 patients. CONCLUSIONS: Medial shrinkage using monopolar thermal energy is effective in treating recurrent patellar instability. Our results were comparable with prior studies using suture plication. The technique avoids additional incisions and decreases operative time. LEVEL OF EVIDENCE: Level IV, therapeutic prospective cohort study.

Outcome of endoscopic bladder transection.

OBJECTIVE: To determine the clinical, symptomatic and objective urodynamic outcome of patients undergoing endoscopic bladder transection. PATIENTS AND METHODS: The study included 20 men and 30 women (mean age of 50 +/- 15 years, range 20-86) who underwent endoscopic bladder transection. Their underlying diagnoses were idiopathic detrusor instability (41), enuresis with instability (6), multiple sclerosis (2) and Parkinson's disease (1). A full-thickness endoscopic transection of the bladder was performed under general anaesthesia. Subjective assessment was performed using symptom scores (0-14 points) and a Visick grading system (group A-E). Objective assessment was carried out using urodynamic studies. The mean follow-up period was 6 years (57 +/- 22 months, range 6-85). RESULTS: The mean hospital stay was 8 +/- 3 days (range 3-22). No patients died after the operation. Postoperative complications included extra-peritoneal extravasation (2), recurrent urinary tract infection (5) and urethral stricture (1). Symptom scores before and after the operation were 9 +/- 2 (range 4-14) and 8 +/- 3 (range 1-14) points respectively. The overall outcome of the procedure was satisfactory in only eight (16%) patients. The mean duration of symptomatic relief was 17 weeks (range 3-53). There was no significant difference between urodynamic results before and after the operation. Bladder instability observed in all patients before operating was demonstrated in 93% of patients after the operation. CONCLUSION: The results of our study suggests that endoscopic bladder transection produces only a transient symptomatic relief in a few of those patients who have failed to respond to pharmacological manipulations. We do not feel that its continued role is justified.

The effects of post-surgical administration of goserelin plus anastrozole compared to goserelin alone in patients with severe endometriosis: a prospective randomized trial.

BACKGROUND: Among patients using GnRH analogues for endometriosis it has been postulated that peripheral and inflammation-induced in-situ aromatization of adrenal androgens are probably the main reasons for the high rates of failure during follow-up. We hypothesized that in cases with premenopausal severe endometriosis, use of a combination of anastrozole and goserelin to achieve almost maximal endocrine blockade of estrogen synthesis after conservative surgery may increase the pain-free interval and reduce the recurrence rates as compared to goserelin alone. METHODS: In a prospective randomized trial, we evaluated the efficacy of using either a combination of anastrozole and goserelin for 6 months or goserelin alone for 6 months after conservative surgery for severe endometriosis. The primary outcome measures were the symptom recurrence rates and the impact of treatment on endometriosis-related multidimensional score. The secondary outcome measures were the impact of allocated treatment regimens on menopausal quality of life and on lumbar spine bone mineral density (BMD). RESULTS: When we analyzed the Kaplan-Meier survival curves, we detected a statistically significant advantage of goserelin plus anastrozole as compared to goserelin only, in terms of the median time to detect symptom recurrence (>2.4 versus 1.7 months; log-rank test; P=0.0089). This statistically significant advantage occurred with a relative risk of 4.3 [95% confidence interval (CI) 1.3-9.8]. Three cases out of 40 recurred in the goserelin plus anastrozole arm (7.5%), whereas we detected recurrences in 14 cases out of 40 cases in the goserelin-only arm (35%) during the follow-up period of 24 months. Based on these data, the interpretation of Kaplan-Meier curves indicates that at the end of follow-up, 54.7 versus 10.4%, respectively, of the patients were free of recurrence. The mean of the differences in terms of Deltabaseline-24 months post-medical therapy multidimensional score were statistically significant in favour of goserelin and anastrozole (9.2 +/- 2.1 versus 6.7 +/- 2.8; paired t-test; P<0.0001; 95% CI 1.5-4.0). We observed a statistically significant difference in suppression of estradiol concentrations and a significantly greater BMD loss at the end of treatment in the goserelin and anastrozole arm as compared to goserelin-only arm. However, this did not elicit deterioration in menopausal quality of life and the observed bone loss was not significant in terms of DeltaBMD between the groups at 2 years of treatment withdrawal. CONCLUSIONS: Six months of treatment with anastrozole and goserelin as compared to goserelin alone increased the pain-free interval and decreased symptom recurrence rates in patients following surgery for severe endometriosis. Furthermore, menopausal quality of life and BMD at 2 years after medical therapy remained unaffected.

Multimodality management of recurrent adult malignant gliomas: results of a phase II multiagent chemotherapy study and analysis of cytoreductive surgery.

Fifty-one adult patients with recurrent malignant gliomas were treated in a Phase II trial of multidrug chemotherapy (6-thioguanine, dibromodulcitol, procarbazine, 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea, 5-fluorouracil, and hydroxyurea). Thirty-one patients underwent radical tumor debulking, before the administration of chemotherapy. Fifty-seven percent of all patients had either an objective radiographic response or stabilization of disease after the institution of therapy. The overall median survival time (MST) was 40 weeks; it was 79 and 33 weeks for anaplastic astrocytoma and glioblastoma patients, respectively. The overall median time to tumor progression (MTP) was 19 weeks--32 weeks for anaplastic astrocytoma patients and 13 weeks for glioblastoma patients. Serious chemotoxicity occurred in 35% of patients without permanent morbidity or mortality. The factors that affected response (including disease stabilization), MTP, and MST were identified through a multivariate statistical analysis. A longer MTP was associated with higher Karnofsky scores, lower grade initial histology, lack of prior chemotherapy, greater degree of myelotoxicity, smaller postoperative tumor volumes, greater extent of surgical resection, and a local versus diffuse recurrence pattern. A longer MST was associated with higher Karnofsky scores, lower grade histology at the time of recurrence, greater degree of myelotoxicity, and lobar versus deep tumor location. Response (including disease stabilization) correlated with higher Karnofsky scores, lower grade histology (initial and current), prior lower grade histology, smaller preoperative tumor volume, longer intervals from the time of initial diagnosis, and absence of prior chemotherapy. These results suggest that, in addition to established prognostic factors such as Karnofsky scores, other factors including prior chemotherapy administration, patterns of tumor recurrence, and tumor location may be important variables to consider in future Phase II-III clinical trials. Of the treatment variables analyzed, greater surgical debulking and smaller postoperative tumor volumes were associated with prolonged MTP but not MST, and greater myelotoxicity had a positive association with all outcomes. The significance of this latter relationship and its relevance to chemotherapy dosing will require further study. Standardization in the design and reporting of clinical trials and the use of computer-assisted tumor volume calculations to assess the extent of surgical resection and the response to therapy are advocated.

Mucoepidermoid carcinoma of the major salivary glands: clinical and histopathologic analysis of 234 cases with evaluation of grading criteria.

BACKGROUND: The authors had previously conducted an investigation of minor salivary gland mucoepidermoid carcinoma, in which they demonstrated that certain clinical and histopathologic features were useful in predicting biologic outcome. The current study investigated the usefulness of these features in determining the prognoses of patients with mucoepidermoid carcinomas of the major salivary glands. METHODS: Clinical data and 15 histopathologic features were compared in 4 patient groups based on outcome after initial treatment. The outcome groups were 1) survival without disease, 2) survival with tumor recurrence only, 3) survival with metastasis, and 4) death related to tumor. A numeric score was assigned to each unfavorable histopathologic feature. Low grade tumors had scores of 0-4. Intermediate grade tumors scored 5 or 6. High grade tumors had scores higher than 6. RESULTS: Most patients (75%) were tumor free after the initial treatment. Twenty-one patients (9%) had local recurrence only, 12 (5%) demonstrated metastasis and survived, and 25 patients (11%) died of their disease. CONCLUSIONS: Clinical features associated with metastasis or death were more advanced age, tumor size, and preoperative symptoms. Histopathologic features that correlated with poor outcome were cystic component less than 20%, 4 or more mitotic figures per 10 high-power fields, neural involvement, necrosis, and anaplasia. All five of these histopathologic features demonstrated statistical prognostic significance when parotid gland tumors from Groups 1 and 4 were compared (P < 0.001). The point-based grading system demonstrated a statistically significant correlation with outcome for parotid tumors but not for submandibular tumors. The authors' findings indicate that patients with tumors of equal histopathologic grade have a better prognosis when their tumors are in the parotid gland than when their tumors are in the submandibular gland. Six of eight submandibular tumors that metastasized or resulted in death were low grade lesions, and none were high grade.

Treatment of recurrent hepatitis C in liver transplant recipients.

The course of hepatitis C is accelerated after transplantation, with an average of 25% of patients developing cirrhosis within 5 years of transplantation. Consequently, the 5- and 10-year graft survival rates in hepatitis C virus (HCV)-infected patients are significantly lower than in HCV-uninfected patients. Therapeutic interventions to prevent HCV recurrence and/or alter the rate of disease progression after transplantation are desirable. Prophylactic therapy in the form of polyclonal HCV antibodies has not been effective at prevention of HCV re-infection, but one study suggests that higher-dose therapy may modify the severity of early disease recurrence. Pre-emptive antiviral therapy has modest efficacy and generally is poorly tolerated. Live donor liver transplant recipients and recipients with low model of end-stage liver disease scores pretransplantation may tolerate pre-emptive therapy best. The treatment of recurrent established disease with a combination of interferon and ribavirin has been the mainstay of management. Similar to pre-emptive therapy, tolerance is reduced and dose reductions are frequent. The sustained virologic response rates are less than 45% in studies to date. Histologic and biochemical improvements generally are more frequent than virologic responses. Overall, the treatment of HCV disease in transplant recipients leaves much to be desired and there is an urgent need of new HCV therapies in this patient population.

Matrix metalloproteinase-2 and matrix metalloproteinase-9 expressions correlate with the recurrence of intracranial meningiomas.

BACKGROUND: We studied whether or not the expressions of MMP-2 and MMP-9 were correlated with the proliferative potential or recurrence of intracranial meningiomas. METHODS: The expressions of MMP-2 and MMP-9 of 56 meningioma tissues were examined and scored by immunohistochemistry (IHC). Expressions of the mRNA of each MMP were also examined by reverse transcriptase polymerase chain reaction (RT-PCR) assay in 15 cases. The relationships between IHC score and each of age, sex, tumor location, histology, MIB-1 labeling index (LI), and recurrence or regrowth rate were studied. RESULTS: Nine of 56 cases showed recurrence or regrowth. IHC revealed that MMP-2 was highly expressed in 13 of 56 cases, whereas MMP-9 was highly expressed in 22 of 56 cases. Among the 15 cases analyzed by RT-PCR assay, MMP-2 and MMP-9 were expressed in 9 and 13 cases, respectively. Based on the Kaplan-Meier curve, the high expressions of MMPs were related to recurrence/regrowth (MMP-2: p < 0.001; MMP-9: p < 0.05). No significant relationship was observed between the expressions of MMPs and either age, sex, tumor location, or MIB-1 LI. CONCLUSIONS: Our study indicated that MMP-2 and MMP-9 expressions are prognostic factors predicting the recurrence of meningioma, independent of proliferative potential.

Invasive squamous cell carcinoma of the uterine cervix. V. Late local recurrences after radiation therapy.

In 26 patients with late local recurrent invasive squamous cell carcinoma of the uterine cervix, primary and recurrence biopsies have been compared with respect to a malignancy grading system. In patients with 16 points or more (n = 13) there was no significant change between estimations. In patients scoring less then 16 points (n = 13), 7 patients had a significant rise in tumour host score indicating the possibility of new prognostic factors occurring. The concept of recurrence is discussed against the background of these findings.

Emergency carotid artery stent placement in patients with acute ischemic stroke.

BACKGROUND AND PURPOSE: An effective intervention has not yet been established for patients with acute ischemic stroke who present with serious neurologic symptoms due to occlusion or a high-grade stenosis of the internal carotid artery (ICA). The aim of our retrospective study was to investigate the feasibility, safety, and efficacy of emergency carotid artery stent placement to improve neurologic symptoms and clinical outcome. METHODS: Of 896 consecutive patients with acute ischemic stroke who were admitted to our institution within 7 days of onset from July 2000 to June 2003, 17 patients (1.9%) with occlusion or a high-grade stenosis of the ICA underwent emergency carotid artery stent placement. We reviewed their records for neurologic outcome, per the National Institutes of Health Stroke Scale (NIHSS) score, before and at 7 days after stent placement; clinical outcome, per the modified Rankin Scale score (mRS), at 90 days; frequency of procedure-related complications within 30 days; and recurrence rate of ipsilateral ischemic stroke within 90 days. RESULTS: Carotid lesions were dilated completely in all patients. Median NIHSS scores before emergency stent placement and at 7 days were 12 and 5, respectively, showing significant improvement (P < .01, Wilcoxon rank sum test). Ten patients (59%) had favorable outcomes (mRS score 0-1) at 90 days. Irreversible complications occurred in two patients (12%): distal embolism in one and intracerebral hemorrhage in the other. No ipsilateral ischemic stroke recurred. CONCLUSION: Emergency carotid artery stent placement can improve the 7-day neurologic outcome and may improve the 90-day clinical outcome in selected patients with ischemic stroke.

A pilot study to explore the predictive validity of 4 measures of falls risk in frail elderly patients.

OBJECTIVES: To test the hypothesis that scores on 4 falls risk measures will differ significantly in patients reporting recurrent falls compared with those who do not; and to explore the validity of each measure to predict such falls status. DESIGN: A convenience sample was tested to establish the sensitivity and specificity of the Functional Reach Test, Timed Up & Go test, one-leg stance test (OLST), and balance subsection of the Performance Oriented Mobility Assessment (B-POMA). A 12-month retrospective falls history was used to identify recurrent fallers. SETTING: A day hospital for the elderly. PARTICIPANTS: Convenience sample of 30 day hospital patients. The inclusion criteria were: ability to rise from a chair and walk 6m; no severe cognitive impairment or blindness; age 65 years or older. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Scores on the 4 tests and retrospective falls histories. RESULTS: Scores on the B-POMA and OLST showed significant differences between fallers and nonfallers (P<.05). An OLST time of 1.02 seconds or less (odds ratio [OR]=15.2; 95% confidence interval [CI], 1.72-133.95) and B-POMA score of 11 or less (OR=18.5; 95% CI, 2.05-167.79) were predictive of day hospital patients having a history of recurrent falls. CONCLUSIONS: OLST and B-POMA both have potential as screening tools for risk of falls, but this observation requires confirmation in a prospective study.

Prognostic effects of causative virus in hepatocellular carcinoma according to the Japan integrated staging (JIS) score.

BACKGROUND: The Japan integrated staging (JIS) score is recognized to be useful in managing hepatocellular carcinoma (HCC). We evaluated the effects of the causative virus in patients stratified by this system. METHODS: We compared clinicopathologic features, cumulative and tumor-free survival rates, and causes of death between 301 hepatitis C virus-positive patients (HCV group) and 60 hepatitis B virus-positive patients (HBV group). RESULTS: Among patients with low JIS scores (0 or 1), the proportions of patients with high aspartate and alanine aminotranferase activities, moderate-to-severe active hepatitis, and with cirrhosis were significantly higher in the HCV than in the HBV group. Among patients with high JIS scores (2 to 4), the proportion with moderate-to-severe active hepatitis was also significantly higher in the HCV group. In patients with low JIS scores, those in the HCV group had significantly lower tumor-free and cumulative survival rates than those in the HBV group. Although no patient in the HBV group died of causes other than liver disease (HCC or hepatic failure), some patients in the HCV group died of causes other than liver disease. The proportion of patients who died because of HCC recurrence tended to be higher among patients with high JIS scores than among patients with a low JIS score. CONCLUSIONS: The effects of viral status on survival outcomes are greatest in patients with JIS scores of 0 or 1.

CD15 (LeuM1) immunoreactivity: prognostic factor for sporadic and hereditary medullary thyroid cancer? Study Group on Multiple Endocrine Neoplasia of Austria.

Patients treated for sporadic and hereditary medullary thyroid carcinoma (MTC) have varying rates of persistent disease, recurrence, and survival. The aim of this study was to correlate the immunoreactivity of the monoclonal antibody CD15 (LeuM1) to initial clinical findings and the outcome of treatment. The primary tumors of 75 patients with sporadic MTC, 7 with hereditary disease, and 3 members of MEN 2A families were studied. Of these subjects 74 (87%) showed no or little immunoreactivity (< 15% positive cells; score 0) in most tumors. The remaining 13% had surgery for tumors with more than 15% cells with positive staining (score I). There was no correlation between LeuM1 immunoreactivity and sex, age, and type of MTC. There was, however, a significant correlation with the pTNM classification and UICC staging. The prognosis for patients with score 0 was significantly better than score 1 patients. CD15 immunoreactivity appears to be a predictive factor in sporadic and hereditary MTC. Lymph node dissection seems to be more successful in patients with score 0 tumors than in those with score 1 tumors. The question of reoperation in patients with recurrence of disease (especially with biochemical recurrence or persistence) should be discussed on the basis of CD15 immunoreactivity.

Hepatocellular carcinoma recurrence after percutaneous ablation therapy: helical CT patterns.

BACKGROUND: To categorize the helical computed tomographic (CT) intrahepatic recurrence patterns of hepatocellular carcinoma (HCC) after treatment with percutaneous ablation procedures. METHODS: Double-phase helical CT studies of 67 patients with HCC recurrence were reviewed. The study population had undergone percutaneous ablation therapy procedures (multisession or single-session ethanol injection therapy, radiofrequency thermal ablation therapy, and interstitial laser photocoagulation therapy) for 120 HCC nodules. RESULTS: Four patterns were defined. (A) Enhancing tissue within the edge of the ablated nodule on arterial phase images (ingrowth): this pattern was seen in five treated lesions (4.2% of all treated nodules) in five patients (7.5% of all patients with recurrence) 3-7 months after treatment (mean = 4 months). (B) Enhancing tissue around the treated nodule but continuously to its border on arterial-phase images (outgrowth): this pattern was found in 12 (10%) treated lesions in 12 patients (18%) 3-6 months after ablation (mean = 4 months). (C) Enhancing tissue within the same segment of the treated nodule on arterial phase images (spread): this pattern was detected in 10 (8%) treated lesions in 10 patients (15%) 3-6 months after treatment (mean = 5 months). (D) Enhancing tissue within different segments from the treated nodule on arterial phase images (progression): this pattern was identified in 34 patients (51%) with 53 (44%) treated tumors 5-22 months after ablation (mean = 8 months). A mixed pattern was found in six subjects (9%) with seven (6%) treated nodules. Among the 61 patients with a nonmixed pattern, there were 85 treated nodules with persistent necrosis, 17 treated nodules with local recurrence (pattern A or B), and 107 new nodules due to nonlocal recurrence (pattern C or D). Portal phase enhanced images and especially unenhanced images showed a lower detection rate and a lower lesion-to-liver conspicuity score (for all patterns but mainly for pattern C). CONCLUSION: Four patterns of recurrence after percutaneous ablation procedures can be categorized on double-phase helical CT and are best depicted on arterial phase images. Knowledge of these patterns is relevant for early detection and may be helpful in understanding the recurrence mechanism.

Early clinical outcomes after subfascial endoscopic perforator surgery (SEPS) and saphenous vein surgery in chronic venous insufficiency.

BACKGROUND: Subfascial endoscopic perforator surgery (SEPS) has recently become popular as a minimally invasive way to treat chronic venous insufficiency (CVI) of the lower extremities. We report the early clinical outcomes of SEPS and saphenous vein surgery in a prospective series of Chinese patients who presented with severe CVI. METHODS: All patients referred to our hospital for the management of severe CVI (class IV disease or above) after January 1998 underwent SEPS using an ultrasonic scalpel in conjunction with saphenous vein surgery. All patients were followed up prospectively to assess ulcer healing, ulcer recurrence, and symptoms after SEPS. Clinical outcome was evaluated by the scoring system suggested by the Consensus Committee of the American Venous Forum on Chronic Venous Disease. RESULTS: Over a 24-month period, we performed 36 SEPS on 31 patients. Nineteen lower extremities (53%) had active or healing ulcers. Sapheno-femoral ligation was also performed in 33 limbs (92%). Four limbs (11%) developed superficial wound infection, and two (6%) had saphenous nerve dysesthesia. The mean clinical score and disability score decreased from 8.42 to 3.42 and 1.45 to 0.31 respectively, after a median follow-up of 14 months (range, 6-22) (p < 0.005). Eleven ulcers (58%) healed within 6 weeks after surgery. At 1-year follow-up, ulcer recurrence was found in two legs (11%). CONCLUSION: SEPS is safe and feasible. Early clinical results have shown a promising outcome in patients with severe chronic venous insufficiency.

Results of the laparoscopic Heller-Dor procedure for pediatric esophageal achalasia.

BACKGROUND: Esophageal achalasia is not a frequent disorder in children and different treatments have been proposed during past decades. This study reviews the results of the laparoscopic Heller-Dor procedure performed in pediatric patients in two different surgical units. METHODS: We included the patients aged <14 years with a minimum follow-up of 6 months operated on in the period 1994-2001. A single longitudinal anterior esophageal myotomy (Heller) and a 180 degrees anterior gastropexy (Dor) were laparoscopically performed. The patients were checked to detect intra- or postoperative complications and recurrence. RESULTS: Twenty children were operated on. Mean follow-up was 45 months (range 6-102). Postoperative clinical score was Visick 1 in 15 cases and Visick 2 in five. CONCLUSIONS: As complication and recurrence rates are very low we consider modified Heller myotomy and Dor gastropexy through a laparoscopic approach our first choice to treat esophageal achalasia in the pediatric population.

Maximum tumor diameter is an independent predictor of prostate-specific antigen recurrence in prostate cancer.

Maximum tumor diameter has been shown to correlate with multiple predictors of clinical outcome in prostate cancer. In the current study, we prospectively analyze whether maximum tumor diameter is a significant predictor of prostate-specific antigen (PSA) recurrence. The study population consisted of 364 patients who underwent radical prostatectomy for prostate cancer. Prostatectomy specimens were evaluated by whole-mount processing of the entire prostate. Maximum tumor diameter was measured from the whole-mount sections of the prostate. Spearman's coefficient of rank correlation was used to correlate tumor diameter with continuous variables. T-tests or analysis of variance (ANOVA) tests were performed to determine if tumor diameter was significantly associated with other clinical and pathologic variables. The effect of clinical and pathologic variables on time to recurrence was analyzed using Cox regression. The mean tumor diameter for all patients was 1.73 cm (range, 0.02-4.40 cm). Maximum tumor diameter was associated with preoperative PSA (r=0.22, P<0.0001), prostate weight (r=-0.12, P=0.028), tumor volume (r=0.87, P<0.0001), Gleason score (r=0.29, P<0.0001), and pathologic stage (P<0.0001). Cox multiple regression was performed to test the prognostic value of maximum tumor diameter adjusting for pathologic stage, Gleason score, and surgical margin status. Increased maximum tumor diameter was associated with shorter time to PSA recurrence (hazard ratio=1.70, 95% confidence interval 1.13-2.56, P=0.01), controlling for risk factors, Gleason score, and surgical margin status. We conclude that maximum tumor diameter is a significant predictor of biochemical recurrence in patients with prostate cancer.
