Semiconstrained total elbow arthroplasty in the context of treated previous infection.

Previous infection has been considered a strict contraindication to implantation or reimplantation of an elbow prosthesis. The purpose of this study was to investigate whether these patients can in fact be successfully treated with a prosthetic arthroplasty given previous treatment of the infection. Ten consecutive prosthetic arthroplasties performed in patients with documented infections in the elbow were retrospectively reviewed. Seven of the patients had infectious complications of total elbow arthroplasties that led to resection. Two patients had previous infections from septic joints and 1 from open reduction internal fixation. The median interval of time from infection treatment to final implant was 45 months (3.8 years). All arthroplasties were performed by the same surgeon with a modified Coonrad-Morrey, semiconstrained prosthesis. Patients were monitored for clinical signs of infection including radiographic and serologic studies and clinical evaluation based on the Mayo Elbow Performance Score. Mean surveillance was 4 years (range 2.8 to 5.4 years). Eight of the 10 cases have not shown signs of infection at the latest assessment. Two have had recurrent infections. The time interval from the original infection to latest implantation did not correlate with infection recurrence. Among those 8 without recurrent infection, 7 had excellent and 1 had satisfactory results according to the Mayo Elbow Performance Score. The recurrent infections were rated as failures. The average score was 32 before and 81 after surgery. The average pain score was 15 before surgery, and the average postoperative pain score was 40. Salvage of previously infected elbows with prosthetic arthroplasty can provide excellent results in a significant proportion of patients. Although the procedure offers superior functional outcomes compared with the alternative treatment options, it is technically demanding.

Experience of cardiac rehabilitation after coronary artery surgery: effects on health and risk factors.

OBJECTIVE: Cardiac rehabilitation (CR) programs are provided to support the recovery process following acute myocardial infarction and coronary artery bypass grafting (CABG). Attendance varies. We related attendance following CABG to severity of cardiac symptoms, general health status (Short Form-36) and prevalence of modifiable coronary artery disease (CAD) risk factors. METHODS: 209 patients due to undergo CABG were recruited and assessed preoperatively as well as at a mean of 16.4 months postoperatively. General health status was measured using the Short Form-36 questionnaire. Severity of cardiac symptoms was assessed on a visual analogue scale. Modifiable coronary artery disease risk factors (smoking, body mass index, hypertension and elevated cholesterol) and social deprivation index were noted. RESULTS: There were ten early and three late deaths. Thirteen patients withdrew consent for investigation, therefore 183 were fully studied. Of these 65.0% completed a CR programme and 24.6% did not attend any programme; 10.4% partially completed (less than 50% of time) and were excluded from analysis. Nonattenders were more likely to be smokers (P=0.002), diabetic (P=0.028) and were more from socially deprived geographical areas (P=0.013), but the proportion of patients with BMI>25, BP>140/90 or cholesterol >5.0 mmol l(-1) were the same. There were no differences in age, preoperative NYHA score, number of grafts, angina recurrence (46 vs. 38%, P=0.35) or breathlessness (62 vs. 69%, P=0.40) between attenders and nonattenders. The severity scores of angina (2.7 vs. 3.2, P=0.286) and breathlessness (3.5 vs. 3.6; P=0.79) were no different. However, four of the eight health domains measured showed significantly better values for attenders than nonattenders; namely: general health (60 vs. 46%, P=0.001), physical function (64 vs. 51% P=0.01), role limitation physical (48 vs. 29%; P=0.02) and social function 74 vs. 62%, P=0.04). CONCLUSIONS: This is the first report using SF 36 to evaluate benefits from attending CR. Higher general health scores (SF-36) were associated with attendance at CR although CAD risk factors and cardiac symptoms were not improved but this may be due to the long interval between assessments.

Ki-67 immunostaining and prognosis in laryngeal cancer.

The expression of the antigen defined by the Ki-67 antibody in paraffin sections from 154 biopsies of laryngeal squamous cell carcinomas was examined. There was a significant difference in Ki-67 expression between the control group and the patients with cancer (P < 0.001). There was no significant difference in the Ki-67 score between the patients with recurrence and the patients with a satisfactory outcome after treatment. There was no significant correlation between the Ki-67 score and the patient's age and sex, T and N stage and site of the tumour. The survival time of patients with a Ki-67 score > 30 was shorter than patients with a Ki-67 score < or = 30 but the difference did not reach statistical significance (P = 0.055). Multivariate analysis indicated that the only important prognostic factor was the existence of lymph node metastases. We could not confirm the value of Ki-67 as a prognostic factor in laryngeal cancer. Ki-67 score may assist in differentiating malignant from benign laryngeal epithelium.

The limited significance of a longer duration of neoadjuvant hormonal therapy prior to radical prostatectomy for high-risk prostate cancer in Japanese men.

INTRODUCTION: The objective of this study was to evaluate the therapeutic significance of a longer duration of neoadjuvant hormonal therapy (NHT) followed by radical prostatectomy (RP) in Japanese men with high-risk prostate cancer. MATERIALS AND METHODS: This study included a total of 42 patients with high-risk prostate cancer who were treated with NHT for >or=8 months prior to RP. In this series high-risk prostate cancer was defined as clinical stage T2c or T3, pretreatment serum prostate-specific antigen (PSA) >20 ng/ml and/or a biopsy Gleason score of 8-10. Biochemical recurrence was defined as a serum PSA level of >or=0.2 ng/ml. The data of these patients were retrospectively reviewed to clarify the relationships between treatment outcomes and various clinicopathological parameters. RESULTS: The clinical stage was T2c in 13 patients and T3 in 29, the median value of pretreatment serum PSA was 43.3 ng/ml (range 9.7-322.2), and the biopsy Gleason score was 6 in 3 patients, 7 in 16 and >or=8 in 23. Following NHT (median 12 months, range 8-27), the median value of serum PSA decreased to 0.05 ng/ml (<0.01-18.3 ng/ml), and 15 patients (35.7%) were pathologically downstaged. During the median follow-up of 38 months (range 8-58), 11 patients (26.2%) developed biochemical recurrence, and the multivariate analysis identified pretreatment serum PSA, biopsy Gleason score and percentage of positive biopsy core as independent predictors of biochemical recurrence. The 3-year biochemical recurrence-free survival rate of the 42 patients was 68.3%, which was not significantly different from that of 34 patients who underwent RP for high-risk prostate cancer without NHT during the same period. CONCLUSION: A longer duration of NHT followed by RP for patients with high-risk prostate cancer resulted in a comparatively favorable outcome. However, despite the nonrandomized retrospective analysis, the present findings suggest no significant impact of long-term NHT on biochemical recurrence. Longer follow-up is needed to determine whether this therapeutic strategy is beneficial for high-risk prostate cancer patients.

Renal cell carcinoma recurrence after nephrectomy for localized disease: predicting survival from time of recurrence.

PURPOSE: Prognostic factors for patients with metastatic renal cell carcinoma (RCC) are well established. However, the risk profile is unknown for patients with recurrent RCC after a nephrectomy for localized disease. PATIENTS AND METHODS: From January 1989 to July 2005, we identified patients with localized RCC treated by nephrectomy who subsequently developed recurrent disease. We applied a validated prognostic scoring system previously developed for patients with metastatic RCC. Each patient was given a total risk score of 0 to 5, with one point for each of five prognostic variables (recurrence < 12 months after nephrectomy, serum calcium > 10 mg/dL, hemoglobin < lower limit of normal, lactate dehydrogenase > 1.5x upper limit of normal, and Karnofsky performance status < 80%). Patients were categorized into low- (score = 0), intermediate- (score = 1 to 2), and high-risk subgroups (score = 3 to 5). RESULTS: Our final cohort included 118 patients, with a median survival time of 21 months from the time of recurrence. Median follow-up time for survivors was 27 months. Overall survival was strongly associated with risk group category (P < .0001). Low-risk, intermediate-risk, and high-risk criteria were fulfilled in 34%, 50%, and 16% of patients, respectively. Median survival time for low-risk, intermediate-risk, and high-risk patients was 76, 25, and 6 months, respectively. Two-year overall survival rates for low-risk, intermediate-risk, and high-risk patients were 88% (95% CI, 77% to 99%), 51% (95% CI, 37% to 65%), and 11% (95% CI, 0% to 24%), respectively. CONCLUSION: At disease recurrence after nephrectomy for localized disease, a scoring system based on objective clinical and laboratory data provides meaningful risk stratification for both patient counseling and clinical trial entry.

Enhanced reverse transcriptase-polymerase chain reaction for prostate specific antigen as an indicator of true pathologic stage in patients with prostate cancer.

BACKGROUND: As up to 50% of all patients with prostate cancer who have undergone radical prostatectomy are found to be understaged subsequent to surgery, a more sensitive early staging modality currently is needed. A molecular assay that detects prostate specific antigen (PSA)-synthesizing cells in the peripheral circulation of patients with prostate cancer is described. METHODS: An enhanced reverse-transcriptase polymerase chain reaction (RT-PCR) assay specific for PSA mRNA was performed on RNA extracted from blood drawn from 94 patients before radical prostatectomy. Surgical specimens were examined to determine the extent of tumor spread. The assay was compared with imaging modalities, digital rectal examination, and serum PSA level as predictors of pathology. Additionally, patients were monitored postoperatively by serum PSA level to determine any potential correlation between patient RT-PCR scores and subsequent tumor recurrence. RESULTS: Postoperative pathology revealed that 36 of the 94 patients had extraprostatic disease at the time of surgery. Enhanced RT-PCR identified 26 of these patients from preoperative blood specimens (72% sensitivity). The test was negative for 51 of the 58 patients with organ-confined disease (88% specificity). An odds ratio analysis showed that no other preoperative staging modality was related more strongly to extraprostatic or organ-confined disease. Follow-up PSA determinations revealed that RT-PCR positive patients were at higher risk for a recurrence. At 6 months after surgery, the rates for an increased PSA were 19 and 2% for RT-PCR-positive and -negative patients, respectively. CONCLUSIONS: The data from this follow-up study continue to support the utility of enhanced RT-PCR as an early staging modality for radical prostatectomy candidates.

Vitamin D receptor gene polymorphisms and disease free survival after radical prostatectomy.

BACKGROUND: Vitamin D has been linked with prostate cancer risk in epidemiologic studies and has antiproliferative, prodifferentiation, and antimetastatic properties in experimental systems. Its hormonal activity is mediated by the vitamin D receptor. We investigated whether germ-line genetic variation in the vitamin D receptor impacts progression of prostate cancer after radical prostatectomy. METHODS: We analyzed BsmI and TaqI polymorphisms using archived specimens from a large series of radical prostatectomy patients at a single institution. Our series included 428 white men (WM) and 310 African-American men (AAM) who were carefully and uniformly staged and followed for 5-10 years. RESULTS: The distribution of polymorphisms varied between WM and AAM. There was little association between genotype and extent of disease at diagnosis, Gleason score, preoperative PSA, or recurrence overall. Among WM with locally advanced disease, however, the BsmI B allele protected against recurrence in models examining gene dose (P = 0.04) and dominant effects (P = 0.05). CONCLUSIONS: Overall vitamin D receptor polymorphisms did not predict pathologic features of prostate cancer but may impact on risk of recurrence among men in certain risk groups. Analysis of polymorphisms may provide clues about the mechanisms through which vitamin D exerts its inhibitory effects on prostate cancer in vivo in men.

Fractal analysis and recurrence quantification analysis of heart rate and pulse transit time for diagnosing chronic fatigue syndrome.

This study aimed to develop a method to distinguish between the cardiovascular reactivity in chronic fatigue syndrome (CFS) and other patient populations. Patients with CFS (n = 23), familial Mediterranean fever (n = 15), psoriatic arthritis (n = 10), generalized anxiety disorder (n = 12), neurally mediated syncope (n = 20), and healthy subjects (n = 20) were evaluated with a shortened head-up tilt test (HUTT). A 10-minute supine phase of the HUTT was followed by recording 600 cardiac cycles on tilt, i. e., 5 to 10 minutes. Beat-to-beat heart rate (HR) and pulse transit time (PTT) were acquisitioned. Data were processed by recurrence plot and fractal analysis. Fifty-two variables were calculated in each subject. On multivariate analysis, the best predictors of CFS were HR-tilt-R/L, PTT-tilt-R/L, HR-supine-DET, PTT-tilt-WAVE, and HR-tilt-SD. Based on these predictors, the 'Fractal & Recurrence Analysis-based Score' (FRAS) was calculated: FRAS = 76.2 + 0.04*HR-supine-DET - 12.9*HR-tilt-R/L - 0.31*HR-tilt-SD - 19.27*PTT-tilt-R/L - 9.42* PTT-tilt-WAVE. The best cut-off differentiating CFS from the control population was FRAS = + 0.22. FRAS > + 0.22 was associated with CFS (sensitivity 70 % and specificity 88 %). The cardiovascular reactivity received mathematical expression with the aid of the FRAS. The shortened HUTT was well tolerated. The FRAS provides objective criteria which could become valuable in the assessment of CFS.

Prostate cancer in the elderly.

Prostate cancer is the second leading cause of cancer deaths among men. Despite earlier diagnosis due to prostate specific antigen (PSA) screening, it is still a disease of the elderly. Diagnosis is based on digital rectal examination (DRE) and PSA assessment. Refinements in PSA testing (age-specific reference ranges, free PSA, PSA density and velocity) increased specificity and limited unnecessary prostate biopsies. Diagnosis in earlier stages (T1 and T2) commonly leads to cure with current treatment modalities. These include radical prostatectomy, external beam radiotherapy and brachytherapy. Other treatment options under development include cryotherapy and high-intensity focused ultrasound. Metastatic prostate cancer is incurable and treatment is based on hormonal therapy. Cytotoxic chemotherapy has only limited role in hormone-independent prostate cancer. Radioisotopes and biphosphonates may alleviate bone pain and prevent osteoporosis and pathological fractures. Follow-up is based on PSA. Prognostic factors for recurrence include stage, Gleason score, pre- and posttreatment PSA. Quality of life issues play an important role in selecting treatment, especially in the elderly due to comorbidities that may negatively affect the overall quality of life. A holistic approach is recommended addressing all quality of life issues without focus only in cancer control.

Endoscopic sinus surgery for the treatment of chronic rhinosinusitis in patients with postirradiated nasopharyngeal carcinoma.

PURPOSE: Our purpose was to evaluate the efficacy and safety of endoscopic sinus surgery (ESS) in patients with nasopharyngeal carcinoma (NPC) after irradiation. MATERIALS AND METHODS: A retrospective study of postirradiated NPC patients who received ESS for the treatment of chronic rhinosinusitis in Taichung Veterans General Hospital. Symptoms, endoscopic findings, and computed tomography were used to evaluate the efficacy of ESS in these patients, and the safety was evaluated by intraoperative findings and complications. RESULTS: Since 1996, 10 postirradiated NPC patients with chronic rhinosinusitis have been treated by ESS and followed up for at least 2 years. The interval between radiotherapy and ESS was from 4 months to 16 years. After surgery, 7 patients felt improved except for one patient who died of tumor recurrence and computed tomography scores changed from 6.6 to 3.7, although prolonged nasal crusting was observed in most patients by endoscopy. One patient was complicated with cerebrospinal fluid leakage and the dura defect was immediately repaired without any sequelae. CONCLUSIONS: This study shows that ESS is effective for the treatment of chronic rhinosinusitis in postirradiated NPC patients if they failed medical treatment.

Intracranial facial nerve neurinoma: surgical strategy of tumor removal and functional reconstruction.

BACKGROUND: Three cases with intracranial facial neurinoma underwent tumor removal and facial nerve reconstruction with or without tympanoplasty. Surgical strategy for each case was tailored to: (1) the site of main tumor mass, (2) its extension along the facial nerve, and (3) involvement of the auditory organs. METHODS: Surgeries adopted in the three cases were: transpetrosal approach with intracranial-intratemporal facial nerve anastomosis, middle fossa and transmastoid approach with intratemporal facial nerve anstomosis and tympanoplasty, and middle fossa and transmastoid approach with intracranial-intratemporal facial nerve anastomosis and tympanoplasty. The greater auricular nerve was used as the nerve graft for all three cases. RESULTS: In the follow-up period of 8-13 months there was no tumor recurrence; facial function was scored 20/90 in modified May's scoring system in each case, but two are still in the process of functional recovery. One of the two cases who underwent tympanoplasty showed complete recovery of hearing within 1 month, and the other showed worsened hearing, which was not serviceable at 3 months postoperatively. CONCLUSION: Systematic surgical approach for tumor removal, facial nerve reconstruction, and auditory reconstruction should be considered in cases with intracranial facial neurinoma due to its varied clinical features.

Impact of adjuvant therapy on quality of life in women with node-positive operable breast cancer. International Breast Cancer Study Group.

BACKGROUND: Adjuvant therapy for early breast cancer is effective but may be toxic. Our aim was to investigate the impact of the presence, timing, and duration of adjuvant chemotherapy on patients' perceptions of their quality of life (QL). METHODS: International Breast Cancer Study Group trial VI assessed adjuvant chemotherapy in 1475 premenopausal and perimenopausal patients, and trial VII assessed adjuvant tamoxifen or chemoendocrine therapy in 1212 postmenopausal patients with node-positive breast cancer. Patients were asked to complete a QL questionnaire-single-item linear analogue self-assessment scales measured physical wellbeing, mood, appetite, and perceived adjustment/coping. QL was assessed in this way at the beginning of treatment, 2 months after the start of treatment, every 3 months, and at 1 and 6 months after recurrence. FINDINGS: Baseline QL scores decreased as the number of involved axillary nodes increased (for example, mean mood score: 66.1 for women with one positive node, 66.4 for two to four positive nodes, 61.3 for five to nine positive nodes, and 59.1 for ten or more positive nodes; p = 0.008 for trends), and were lower in patients with oestrogen-receptor-negative than in patients with oestrogen-receptor-positive tumours (61.4 vs 66.3, p = 0.0009). All treatment groups showed substantial improvement in QL scores during adjuvant therapy. Patterns of QL scores reflected presence, duration, and timing of cytotoxic treatment. Longer initial cytotoxic therapy delayed improvement in QL scores. Later cytotoxic therapy had transient adverse effects. Anticipation of future therapy also affected QL scores. INTERPRETATION: Overall, chemotherapy had a measurable adverse effect on QL, but this effect was transient and minor compared with patients' adaptation/coping after diagnosis and surgery. This finding should encourage patients and doctors to choose appropriate adjuvant therapy with less concern for initial toxicity.

Fall-risk screening test: a prospective study on predictors for falls in community-dwelling elderly.

This large prospective cohort study was undertaken to construct a fall-risk model for elderly. The emphasis of the study rests on easily measurable predictors for any falls and recurrent falls. The occurrence of falls among 1285 community-dwelling elderly aged 65 years and over was followed during 1 year by means of a "fall calendar." Physical, cognitive, emotional and social functioning preceding the registration of falls were studied as potential predictors of fall-risk. Previous falls, visual impairment, urinary incontinence and use of benzodiazepines were the strongest predictors identified in the risk profile model for any falls (area under the curve [AUC] = 0.65), whereas previous falls, visual impairment, urinary incontinence and functional limitations proved to be the strongest predictors in the model for recurrent falls (AUC = 0.71). The probability of recurrent falls for subsequent scores of the screening test ranged from 4.7% (95% Confidence Interval [CI]: 4.0-5.4%) to 46.8% (95% CI: 43.0-50.6%). Our study provides a fall-risk screening test based on four easily measurable predictors that can be used for fall-risk stratification in community-dwelling elderly.

Role of vascularised tissue transfer after oncological resection in the upper extremity.

We reviewed 12 patients who had had vascularised tissue transfer after oncological resection in the upper extremity. All patients had immediate reconstruction, and one had a double tissue transfer. Tissues used were skin flaps, free muscles, and vascularised fibulas, for resurfacing the wound, motor recovery, and reconstruction of large bony defects, respectively. All the patients returned early to their daily activities. Although local recurrences were encountered in two patients, they were again rendered disease-free by salvage operations. Two patients had secondary reconstructions using pedicle latissimus dorsi flaps for late problems, including one of the two patients who developed a local recurrence. The mean functional score using the system devised by the Musculoskeletal Tumor Society was 84%. All the upper extremities were successfully rescued with satisfactory function. Vascularised tissue transfer was invaluable for achieving both curative resection of the tumour and a useful upper extremity.

Evaluation of a staging system for infected hip arthroplasty.

A previously reported staging system for prosthetic joint infection was evaluated in 26 consecutive patients with an infected hip arthroplasty. Six patients were treated by a definitive resection arthroplasty whereas the remaining 20 patients received delayed insertion of another hip arthroplasty. Four of the 20 patients (20%) receiving a new prosthesis had reinfection develop. The only variable in common among the patients who had reinfection was the use of a massive femoral structural allograft at reconstruction. Because of the small number of patients in this study, the power of statistical analysis did not allow definitive determination of the effect of the staging system score with respect to recurrent infection. Based on this study, recommendations can be suggested for addition and deletion of certain variables within the existing staging system. Although the concept of a staging system for treatment of an infected hip arthroplasty is promising, the number of patients required to evaluate the use of a staging system will require a multicenter collaborative study.

Uretero-ureterocutaneostomy (wrapped by omentum).

UNLABELLED: The tubularized-incised plate urethroplasty has traditionally been used in children for repairing hypospadias. As shown here, it can also be used successfully in adults, with very good results. The rate of wound healing, infection and complications is the same as in children, as are the cosmetic and functional outcomes. OBJECTIVES: To evaluate the outcome of uretero-ureterocutaneostomy (UUC) wrapped by omentum for palliative cystectomy in symptomatic elderly high-risk patients with high-stage bladder cancer. PATIENTS AND METHODS: The study included 15 patients (14 men and one woman, aged 72-87 years, American Society of Anesthesiology score 3) with symptomatic recurrent bleeding bladder cancer (T2/T3) who were treated with palliative cystectomy. UUC was performed by mobilizing the right pre-vesical divided ureter up to the pelvi-ureteric junction and a high retroperitoneal crossover to the divided left ureter. A stoma was created with a circular 2-cm skin excision and resecting the fatty subcutaneous tissue. Wrapped by the omentum, both well-vascularized ureteric stumps were pulled through a cross-like fascia incision up to skin level. Spatulated and everted, the 'butterfly' flaps were fixed to the skin and underlying omentum. Soft splints were inserted for 21 days and a Karaya ring placed. RESULTS: The postoperative course and stoma healing was normal in 14 of the 15 patients; the sigmoid was resected because of sigmoid diverticulitis in one. The median (range) follow-up was 15 (6-24) months. There was pyelonephritis in one patient, and the dilatation of the upper tract (grade 3) in two returned to grade 2, with new asymptomatic grade 1 dilatation in one other. All patients were without stents and stoma care was provided at home. CONCLUSIONS: This modified UUC by omental wrapping in 15 high-risk patients after palliative cystectomy was simple and safe, and their recovery was uneventful. To date the few patients with stomal obstruction were managed by J catheters, changed every 4-6 months.

Stage B Prostate Cancer: Correlation of DNA Ploidy Analysis With Histological and Clinical Parameters.

BACKGROUND: The ability to accurately predict tumor behavior and patient survival is a problem in managing patients with prostate cancer. Prognostic variables in predicting death from tumor include prostate-specific antigen (PSA) level, histological grade, and clinical stage. Observer subjectivity is inherent in determining grade and stage; thus, criteria that are more objective are needed to identify patients for appropriate treatment. METHODS: The authors correlated flow cytometric nuclear DNA ploidy with Gleason score, PSA level, and recurrence risk in patients who underwent radical retropubic prostatectomy and bilateral pelvic lymphadenectomy between 1987 and 1993 for histopathologic stage B prostate cancer (T2, N0, M0). RESULTS: Of the tumors analyzed, 64% were DNA diploid with a low proliferative fraction, 25% were DNA diploid with a high proliferative fraction, and 11% were DNA aneuploid. DNA aneuploidy was associated with high Gleason grade (7-10). All Gleason grade 10 tumors were DNA aneuploid. Both DNA aneuploidy and high proliferative fraction (S+G2M) were statistically correlated with high Gleason grade and adverse prognosis but not with PSA level or patient age. CONCLUSIONS: A direct relationship is shown between both DNA aneuploidy and a high proliferation index with aggressive biological behavior in stage B prostatic cancer. Objective tumor criteria are needed to choose treatment more selectively for individual patients.
