Functional diagnosis using multimodal spinal cord evoked potentials in cervical myelopathy.

The electrophysiological measurement of spinal cord evoked potentials (SCEPs) has been established as a tool for diagnosing the spinal level responsible for cervical myelopathy. Only a few studies, however, employed multimodal SCEPs for this purpose. The objective of this study was to investigate the correlation between multimodal SCEPs recorded during cervical laminoplasty and magnetic resonance imaging (MRI) abnormalities in 18 patients aged 70 years and older versus 32 patients less than 65 years of age. Both the SCEPs and MRIs showed higher incidences of multiple-level cord involvement in the older group than in the younger group. Discrepancies in the spinal levels involved between the SCEPs and the MRIs were found in 12 patients (67%) for the older group and 6 patients (19%) for the younger group. The accuracy of the MR images in localizing the lesion site was significantly lower in the older group than in the younger group, indicating that MR images tend to show clinically silent cord compression in elderly patients. Because spinal cord compression can appear without functional change in elderly patients, electrophysiological evaluations with intraoperative multimodal SCEP studies are a useful addition to MRI for understanding the pathology of myelopathy.

Effectiveness of an adaptive multimodal treatment in children with Attention-Deficit Hyperactivity Disorder -- global outcome.

BACKGROUND: The meaning of different components within a multimodal treatment of ADHD remains to be further clarified. OBJECTIVE: To evaluate the effectiveness of behaviour therapy and drug treatment within an adaptive and individually tailored multimodal treatment for children with ADHD. METHOD: After an initial psychoeducation n = 75 school-children aged 6-10 years with a diagnosis of ADHD/HKD were assigned to either behaviour therapy (including continued psychoeducation) or medical management with methylphenidate plus psychoeducation. Depending on the effectiveness, the treatment was either terminated (if totally effective) with long-term aftercare and continuation of medication if needed, or (if partially effective) the other treatment component was added (combined treatment), or (if ineffective) the treatment components were replaced. Thus a treatment rationale was applied which resulted in an adaptive and individually tailored therapy -- similar to a strategy that may be useful in clinical practice. RESULTS: Of the children who started with behaviour therapy after initial psychoeducation 26% received a combined treatment in later treatment stages. In most of the cases (82%) with initial medical management, behaviour therapy was added. ADHD symptoms, individually defined behaviour problems and comorbid symptoms were significantly reduced during the course of treatment. On core measures large pre-post effect sizes were found. On teacher ratings combined treatment was more effective than behaviour therapy. CONCLUSIONS: Both, behaviour therapy and combined treatment are effective interventions within an adaptive and individually tailored multimodal treatment strategy.

Multimodal features and prognostic risk assessment in locally advanced gastric cancer patients following neoadjuvant therapy based on machine learning algorithms: a multicenter study.

BACKGROUND: Neoadjuvant therapy (NAT) is recommended for locally advanced gastric cancer (LAGC), but some patients respond poorly. We aimed to construct a multimodal model integrating CT images, transcriptomic sequencing, and clinicopathological data to assess prognosis in LAGC patients receiving NAT. MATERIALS AND METHODS: This multicenter study included 505 LAGC patients who underwent NAT. Radiomic features were extracted from preoperative CT images of 505 patients. RNA-seq was performed on 277 post-NAT specimens, with additional data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases (n&#x2009;=&#x2009;804). Patients were divided into training (168 cases), internal validation (72 cases), and external validation cohorts. Machine learning algorithms identified key radiomic, molecular, and clinical features associated with NAT response, which were then integrated into a multimodal model to predict overall survival (OS) and disease-free survival (DFS). RESULTS: Six radiomic and three molecular features significantly associated with NAT response were selected. Radiomic risk (hazard ratio [HR]: 4.0, P&#x2009;<&#x2009;0.001) and molecular risk (HR: 7.1, P&#x2009;<&#x2009;0.001) were independent prognostic factors. By integrating radiomic risk, molecular risk, and clinical characteristics, a multimodal model (MuMo) was constructed.The C-index results (OS, C-index&#x2009;=&#x2009;0.855; DFS, C-index&#x2009;=&#x2009;0.786) demonstrated that MuMo outperformed the single-modality models and ypTNM staging.Mechanistic analysis suggested that the efficacy of neoadjuvant therapy was significantly enriched in immune-inflammatory pathways. CONCLUSIONS: MuMo can effectively predict postoperative survival risk in LAGC patients receiving NAT, serving as a powerful tool for optimizing prognostic assessment.

Multimodal rehabilitation for faecal incontinence: experience of an Italian centre devoted to faecal disorder rehabilitation.

BACKGROUND: Sphincter exercises and biofeedback therapy have been used to treat faecal incontinence but results have been unpredictable and standards of treatment have not yet been established. The aim of this study was to retrospectively evaluate the effects of a new multimodal rehabilitation model on faecal incontinence. METHODS: All of the rehabilitative procedures are guided by manometric data. Primary study outcome criteria were the determination of changes or deterioration in incontinence, failure to achieve full continence and/or presence of faecal urgency. The clinical outcome was designed according to the Jorge-Wexner incontinence score. RESULTS: Between 1997 and 2001, one hundred forty-nine incontinent patients (85 F and 64 M; age range, 41-73 years; mean age, 60.6 years) underwent multimodal rehabilitation at our outpatient unit. The overall mean incontinence score had significantly improved after treatment ( p<0.001), and 58 patients (38.9%) were symptom free. No patient reported any deterioration in incontinence. Faecal urgency persisted in 23 patients (15.4%). CONCLUSION: In conclusion, multimodal rehabilitation, using manometric study, can modify the incontinence score.

Advanced stage thymomas and thymic carcinomas: results of multimodality treatments.

BACKGROUND: With the aim of evaluating the results of multidisciplinary approaches, we reviewed our experience in multimodality treatment of advanced stage (III and IVA) thymic tumors. METHODS: From 1976 to 2003, 56 patients with Masaoka stage III and IVA thymic tumors underwent a multimodality treatment. Thirty-six patients underwent neoadjuvant chemotherapy, surgery, and postoperative radiotherapy; 20 patients were treated by primary surgery and postoperative radiotherapy (n = 12), chemotherapy (n = 1) or chemoradiotherapy (n = 7). The neoadjuvant or adjuvant chemotherapy consisted of three courses of cisplatin, epidoxorubicin, and etoposide every 3 weeks. Adjuvant radiotherapy consisted of 45 Gy for complete resections or 60 Gy for incomplete resections. RESULTS: The preoperative diagnosis of invasive thymomas was performed in a total of 29 cases: 15 by mediastinotomy, 6 by video-assisted thoracoscopic surgery, and 8 by fine-needle aspiration. In 27 cases no diagnosis was available, but in most of them a thymus-related syndrome was present. Thirty-four patients are still alive (31 disease-free), and 22 have died (2 disease-free). Ten-year survival was 48% and 45.7% for stage III and IVA thymomas, respectively. The presence of myasthenia gravis (p = 0.04) and neoadjuvant chemotherapy (p = 0.004) affected survival significantly. CONCLUSIONS: The multimodality treatment of stage III and IVA thymic tumors allows a good long-term outcome; the neoadjuvant chemotherapy improves the resectability rate and the survival of both stages of the disease.

Multimodality treatment of thymoma: a prospective study.

BACKGROUND: Thymomas are a heterogeneous group of tumors. Treatment of invasive lesions is not well standardized. The aim of this study is to propose a clinicopathologically based protocol for multimodality therapy. METHODS: Between 1965 and 1988, we operated on 83 patients with thymoma who did not receive standardized adjuvant therapy. In 1989, on the basis of the retrospective analysis of the data, we started a multimodality therapy protocol and used it for 65 patients. Twelve patients had medullary thymoma (11 stage I and 1 stage II), 13 had mixed type (6 stage I and 7 stage II), and 40 had cortical thymoma (4 stage I, 11 stage II, 12 stage III, and 13 stage IV). We considered three groups. Group I (n = 18 patients), benign thymoma, included stage I and II medullary and stage I mixed thymomas; radical resection with no adjuvant therapy was performed. Group II (n = 22), invasive thymoma, included stage I and II cortical and stage II mixed thymomas; postoperative chemotherapy plus radiotherapy was always administered. Group III (n = 25), malignant thymoma, comprised stage III and IV cortical thymomas and stage III mixed thymomas; resectable stage III lesions were removed, and highly invasive stage III and stage IV lesions underwent biopsy, neoadjuvant chemotherapy, and surgical resection; postoperative chemotherapy and radiotherapy was administered to all patients. RESULTS: The 8-year survival rate for patients in stages I, II, III, and IV was 95%, 100%, 92%, and 68%, respectively. Patients with medullary thymoma had a 92% 8-year survival rate; those with mixed type, 100%; and those with cortical thymoma, 85%. Group I had an 8-year survival rate of 94%; group II, 100%; and group III, 76%. Survival was compared with that of patients operated on before 1989: differences were not significant for group I; survival improved in group II (100% versus 81%; p = not significant); and group III showed significant improvement (76% versus 43%; p < 0.049). CONCLUSIONS: Multimodality treatment with neoadjuvant chemotherapy and adjuvant chemotherapy plus radiotherapy may improve the results of radical resection and the survival of patients with invasive and malignant thymoma.

Value of accelerated multimodality therapy in stage IIIA and IIIB non-small cell lung cancer.

OBJECTIVES: This study was undertaken to assess accelerated multimodality therapy in patients with IIIA and IIIB non-small cell lung cancer in terms of toxicity, feasibility, response, survival, and recurrence (value) and to identify predictors of pathologic response and improved survival. METHODS: Between October 1994 and September 2000, a total of 105 patients with stage pIIIA (n = 78) or pIIIB (n = 27) non-small cell lung cancer were enrolled in a study of accelerated multimodality therapy, consisting of hyperfractionated radiotherapy with concurrent chemotherapy (paclitaxel and cisplatin) followed by resection and postoperative chemoradiation. Multivariable correlates of pathologic response and survival were assessed. RESULTS: Toxic effects related to induction therapy necessitated hospitalization in 40% of patients (n = 42); treatment-related mortality was 9% (n = 9). With respect to feasibility, 100% of patients completed induction therapy, 93% (n = 98) of cancers were operable, 79% (n = 83) of cancers were curatively resectable, and 77% (n = 81) of patients completed all therapy. Sterilization of mediastinal nodes was similar (P =.6) for pN2 (35%) and pN3 (30%) disease. Median, 2-year, and 5-year survivals were 27 months, 53%, and 32%, respectively. Locoregional recurrence, distant recurrence, and both were seen in 6% (n = 6), 45% (n = 47), and 3% (n = 3) of patients, respectively. Pathologic response was not predictable. Nodal status predicted incrementally decreasing survival for patients with cancers downstaged to ypN0 or ypN1 (n = 35) versus ypN2 (n = 44) versus ypN3 (n = 20; P <.001). In addition, advancing age, squamous histologic type, and higher pT predicted poorer survival. CONCLUSIONS: Accelerated multimodality therapy is equally valuable in IIIA and IIIB non-small cell lung cancers. Despite unpredictable response to induction therapy, younger patients and those with nonsquamous histologic type, sterilization of mediastinal lymph nodes, and lower pT benefit most. A ypN2 stage reduces but does not preclude long-term survival.

Pleural space perfusion with cisplatin in the multimodality treatment of malignant mesothelioma: a feasibility and pharmacokinetic study.

INTRODUCTION: Malignant pleural mesothelioma is an ideal model for testing new locoregional multimodality approaches because of its aggressive local behavior. METHODS: This study was planned to investigate the feasibility, safety, and pharmacokinetics of a multimodality therapy including an operation, pleural space perfusion (60 minutes) with cisplatin (100 mg/m2), hyperthermia (41. 5 degrees C), and postoperative radiotherapy (55 Gy to chest wall incisions). The effects of the extent of resection and perfusion temperature on cisplatin pharmacokinetics were evaluated. Ten patients with epithelial or mixed, stage I or II, malignant pleural mesothelioma underwent the following procedures: group A (3 patients), pleurectomy/decortication and normothermic pleural space antineoplastic perfusion; group B (3 patients), pleurectomy/decortication and hyperthermic perfusion; and group C (4 patients), pleuropneumonectomy and hyperthermic perfusion. Operations were selectively applied depending on tumor extent. Platinum levels were serially measured by atomic absorption in systemic blood, perfusate, lung, and endothoracic fascia. RESULTS: The overall procedure was completed in every case, without any death or toxicity. No lung damage was demonstrated after treatment. Major complications included 1 wound infection and 1 diaphragmatic prosthesis displacement. The mean peak platinum plasma levels were reached within 45 to 60 minutes after perfusion was started. Systemic drug concentrations were greater after pleurectomy/decortication than after pleuropneumonectomy (P =.006). The local tissue/perfusate ratio of platinum concentrations tended to be higher after hyperthermic perfusion rather than normothermic perfusion. CONCLUSION: This multimodality approach is feasible, pharmacokinetically advantageous, and safe enough to undergo further clinical investigations.

Improving treatment planning accuracy through multimodality imaging.

PURPOSE: In clinical practice, physicians are constantly comparing multiple images taken at various times during the patient's treatment course. One goal of such a comparison is to accurately define the gross tumor volume (GTV). The introduction of three-dimensional treatment planning has greatly enhanced the ability to define the GTV, but there are times when the GTV is not visible on the treatment-planning computed tomography (CT) scan. We have modified our treatment-planning software to allow for interactive display of multiple, registered images that enhance the physician's ability to accurately determine the GTV. METHODS AND MATERIALS: Images are registered using interactive tools developed at the University of North Carolina at Chapel Hill (UNC). Automated methods are also available. Images registered with the treatment-planning CT scan are digitized from film. After a physician has approved the registration, the registered images are made available to the treatment-planning software. Structures and volumes of interest are contoured on all images. In the beam's eye view, wire loop representations of these structures can be visualized from all image types simultaneously. Each registered image can be seamlessly viewed during the treatment-planning process, and all contours from all image types can be seen on any registered image. A beam may, therefore, be designed based on any contour. RESULTS: Nineteen patients have been planned and treated using multimodality imaging from November 1993 through August 1994. All registered images were digitized from film, and many were from outside institutions. Brain has been the most common site (12), but the techniques of registration and image display have also been used for the thorax (4), abdomen (2), and extremity (1). The registered image has been an magnetic resonance (MR) scan in 15 cases and a diagnostic CT scan in 5 cases. In one case, sequential MRs, one before treatment and another after 30 Gy, were used to plan patient's initial fields and boost, respectively. Case illustrations are shown. CONCLUSIONS: We have successfully integrated multimodality imaging into our treatment-planning system, and its routine use is increasing. Multimodality imaging holds out the promise of improving treatment planning accuracy and, thus, takes maximum advantage of three dimensional treatment planning systems.

Multimodal patient education program with stress management for childhood and adolescent asthma.

The present study aimed to evaluate a multimodal patient education program carried out during inpatient rehabilitation. The program included cognitive-behavioral stress management training as a main component. The efficacy was examined in comparison to an education program without stress management. In total N=68 patients aged between 8 and 16 years were included in the post-treatment and N=46 patients in the 6 months follow-up assessment. Short- and long-term intervention effects of the multimodal education program were observed in relation to patients' age. The experimental treatment elicited significant improvements in adaptive coping in adolescents aged from 14 to 16 years. In contrast, substantial effects were not yielded for the control treatment. The results suggest that the multimodal patient education training has beneficial effects on stress management in adolescents with asthma. Results are discussed with regard to predictive factors for rehabilitation outcome.

Locally advanced primary breast cancer: medium-term results of a randomised trial of multimodal therapy versus initial hormone therapy.

We report the medium-term (median follow-up=52 months) results of a prospective randomised trial of multimodal therapy (neoadjuvant chemotherapy, Patey mastectomy, postoperative radiotherapy and adjuvant hormone therapy) (n=56) versus initial hormone therapy (n=52) for locally advanced primary breast cancer. Compared with multimodal therapy, initial hormone therapy was associated with reduced number of therapies for disease control (mean=3.6 versus 4.9) and mastectomy rate (31%). Multimodal therapy conferred better initial locoregional control and a longer disease-free interval. Nevertheless, there was no statistically significant differences in the rates of survival, metastasis and uncontrolled locoregional disease, as well as in the time to metastasis between the two therapy groups. Regardless of the therapy groups, oestrogen receptor positivity conferred a lower metastasis rate, better survival and locoregional control. Thus, initial hormone therapy may be a reasonable option for managing locally advanced primary breast cancer, especially for oestrogen receptor-positive tumours.

Locally advanced breast cancer: early results of a randomised trial of multimodal therapy versus initial hormone therapy.

The aim of this study was to investigate initial treatment of locally advanced breast cancer. Patients were randomised to "multimodal" therapy (pre-operative chemotherapy, Patey mastectomy, flap irradiation and adjuvant hormone therapy) (n = 55), or initial "hormone" therapy (n = 53) with further therapy upon tumour progression. The objective response to chemotherapy was 57% (31/54) after four cycles. Of patients on hormone therapy, 36% (19/53) had an objective response and 32% (17/53) disease stasis at a 6 month assessment. At a median 30 months follow-up, there was no notable difference in development of metastases or survival: only 6 patients have uncontrolled loco-regional relapse (4 "hormonal", 2 "multimodal"). The number of treatments per patient required for this loco-regional control was lower in the "hormone" group (mean 2.13 versus 4.20 in the "multimodal" group). This small study has shown that the use of consecutive therapies, with the aim of tumour control, does not appear to compromise outcome in comparison with initial "multi-modal" therapy. Adopting such a policy may allow some patients to avoid unnecessary treatments.

Demonstration of accuracy and clinical versatility of mutual information for automatic multimodality image fusion using affine and thin-plate spline warped geometric deformations.

This paper applies and evaluates an automatic mutual information-based registration algorithm across a broad spectrum of multimodal volume data sets. The algorithm requires little or no pre-processing, minimal user input and easily implements either affine, i.e. linear or thin-plate spline (TPS) warped registrations. We have evaluated the algorithm in phantom studies as well as in selected cases where few other algorithms could perform as well, if at all, to demonstrate the value of this new method. Pairs of multimodal gray-scale volume data sets were registered by iteratively changing registration parameters to maximize mutual information. Quantitative registration errors were assessed in registrations of a thorax phantom using PET/CT and in the National Library of Medicine's Visible Male using MRI T2-/T1-weighted acquisitions. Registrations of diverse clinical data sets were demonstrated including rotate-translate mapping of PET/MRI brain scans with significant missing data, full affine mapping of thoracic PET/CT and rotate-translate mapping of abdominal SPECT/CT. A five-point thin-plate spline (TPS) warped registration of thoracic PET/CT is also demonstrated. The registration algorithm converged in times ranging between 3.5 and 31 min for affine clinical registrations and 57 min for TPS warping. Mean error vector lengths for rotate-translate registrations were measured to be subvoxel in phantoms. More importantly the rotate-translate algorithm performs well even with missing data. The demonstrated clinical fusions are qualitatively excellent at all levels. We conclude that such automatic, rapid, robust algorithms significantly increase the likelihood that multimodality registrations will be routinely used to aid clinical diagnoses and post-therapeutic assessment in the near future.

Multimodal events and moving locations: eye movements of adults and 6-month-olds reveal dynamic spatial indexing.

The ability to keep track of locations in a dynamic, multimodal environment is crucial for successful interactions with other people and objects. The authors investigated the existence and flexibility of spatial indexing in adults and 6-month-old infants by adapting an eye-tracking paradigm from D. C. Richardson and M. J. Spivey (2000). Multimodal events were presented in specific locations, and eye movements were measured when the auditory portion of the stimulus was presented without its visual counterpart. Experiment 1 showed that adults spatially index auditory information even when the original associated locations move. Experiments 2 and 3 showed that infants are capable of both binding multimodal events to locations and tracking those locations when they move.

Urologic and sexual morbidity following multimodality treatment for locally advanced primary and locally recurrent rectal cancer.

AIMS: In the treatment of patients with locally advanced primary or locally recurrent rectal cancer much attention is given to the oncological aspects. In long-term survivors, urogenital morbidity can have a large effect on the quality of life. This study evaluates the functional outcome after multimodality treatment in these patient groups. PATIENTS AND METHODS: Between 1994 and August 1999, 55 patients with locally advanced primary and 66 patients with locally recurrent rectal cancer were treated with multimodality treatment: i.e. high-dose preoperative external beam radiation therapy, followed by extended surgery and intraoperative radiotherapy. The medical records of the 121 patients were reviewed. To assess long-term urogenital morbidity, all patients still alive, with a minimum follow-up of 4 months, were asked to fill out a questionnaire about their voiding and sexual function. Seventy-six of the 79 currently living patients (96%) returned the questionnaire (median FU 14 months, range 4-60). RESULTS: The questionnaire revealed identifiable voiding dysfunction as a new problem in 31% of the male and 58% of the female patients. In 42% of patients after locally advanced primary and 48% after locally recurrent rectal cancer treatment bladder dysfunction occurred. The preoperative ability to have an orgasm had disappeared in 50% of the male and 50% of the female patients, and in 45% of patients after locally advanced primary and in 57% after locally recurrent rectal cancer treatment. CONCLUSION: Multimodality treatment for locally advanced primary and recurrent rectal cancer results in acceptable urogenital dysfunction if weighed by the risk of uncontrolled tumour progression. Long-term voiding and sexual function is decreased in half of the patients. Preoperative counselling of these patients on treatment-related urogenital morbidity is important.

Effect of preemptive multimodal analgesia for arthroscopic knee ligament repair.

BACKGROUND AND OBJECTIVES: Administration of analgesic medication before surgery, rather than at the completion of the procedure, may reduce postoperative pain. Similarly, administration of multiple analgesics, with different mechanisms of action, may provide improved postoperative pain control and functional recovery. The purpose of our study was to compare pain scores and intravenous opioid consumption after outpatient anterior cruciate ligament (ACL) reconstruction in patients who received a multimodal drug combination (intravenous [IV] ketorolac, intra-articular morphine/ropivacaine/epinephrine, and femoral nerve block with ropivacaine) either before surgery or immediately at the completion of the surgical procedure. METHODS: Forty patients presenting for same-day arthroscopic ACL repair using a semitendinosis tendon graft were included in this study. The patients were randomized to receive the following drugs either 15 minutes before skin incision or immediately after skin closure: (1) Ketorolac 30 mg IV. (2) Intra-articular injection of 20 mL ropivacaine 0.25% + morphine 2 mg and epinephrine 1:200,000. (3) Femoral nerve block with 20 mL ropivacaine 0.25%. Verbal pain scores were obtained in the postanesthesia care unit (PACU) and on postoperative days 1, 3, and 7. IV patient controlled analgesia (PCA) morphine consumption in the PACU was also recorded. RESULTS: Verbal pain rating scores were lower in group I (preemptive) for 2.0 hours after arrival in the PACU. There was no difference between groups in pain scores on postoperative days 1, 3, and 7. Mean IV PCA morphine consumption in the PACU was lower in group I (6.4 mg) versus group II (12.3 mg), P <.05. CONCLUSION: Preemptive, multimodal administration of our 3-component analgesic drug combination resulted in lower pain scores during the initial stay in the PACU unit and lower consumption of IV PCA morphine in the PACU. However, pain scores were similar in both groups on postoperative days 1, 3, and 7; thus, there was no measurable long-term advantage associated with preemptive multimodal drug administration.

[Radicular Low Back Pain: Evaluation of Conservative Multimodal Treatment]

OBJECTIVE: In this summary, the preliminary results of studies evaluating medical therapy of radicular low back pain are reported. METHODS: In two prospective cohorts (183 patients) the conservative multimodal inpatient treatment was examined, using the newly developed "Radicular Low Back Pain Score" for the standardized measurement of the radiculopathy. In another sample of 116 patients the preceeding outpatient treatment was documented. RESULTS: A significant short-term improvement with regard to the pain intensity and the radiculopathy was observed after approximately two weeks of therapy. The preceeding outpatient treatment did not comply with recent guidelines. Moreover, it did not influence the outcome of the multimodal inpatient therapy. CONCLUSIONS: The "Radicular Low Back Pain Score" seems to be a suitable instrument for measuring therapy effectiveness. Multimodal medical treatment is an important treatment approach for sciatica, especially after failed outpatient therapy.

Multimodal synchronization of chaos.

An elementary notion of master-slave synchronization that accepts multimodal synchronization is introduced. We prove rigorously that the attractor of a coupled pair in a regime of multimodal synchronization is the graph of a multivalued function. Our framework provides the theoretical basis for some practical tools for detection of multimodal synchrony in experiments. Results are illustrated with the analysis of experiments with coupled electronic oscillators.
