Functional reorganization and recovery after constraint-induced movement therapy in subacute stroke: case reports

Preliminary assessments of the feasibility, safety, and effects on neuronal reorganization measured with transcranial magnetic stimulation (TMS) from Constraint-Induced Movement Therapy (CIMT) of the upper extremity were made in eight cases of subacute stroke. Within fourteen days of their stroke, patients were randomly assigned to two weeks of CIMT or traditional therapy. Baseline motor performance and cortical/subcortical representation for movement with TMS were assessed before treatment. Post-treatment assessments were made at the end of treatment and at three months after the stroke. The TMS mapping showed a larger motor representation in the lesioned hemisphere of the CIMT patients as compared to the controls at the three-month follow-up assessment. The enlarged motor representation in the lesioned hemisphere for hand movement correlated with improved motor function of the affected hand, suggesting a link between movement representation size as measured with TMS and functionality. These results suggest that TMS can be safely and effectively used to assess brain function in subacute stroke and further suggest that CIMT may enhance cortical/subcortical motor reorganization and accelerate motor recovery when started within the first two weeks after stroke.     

Pretreatment With L‐Citrulline Positively Affects the Mucosal Architecture and Permeability of the Small Intestine in a Murine Mucositis Model

Background: Mucositis is a common complication in patients undergoing radiotherapy and chemotherapy. It is associated with pain, poor quality of life, and malnutrition, leading to an increased number of hospital admissions and prolonged hospitalization. The use of immunonutrients may be an alternative treatment option, which may help to improve patient outcome. Objective: Here we assessed the impact of L‐citrulline (CIT) on a murine model of 5‐fluorouracil (5FU)–induced mucositis. Methods: Swiss male mice were randomized into 4 groups: control, CIT, 5FU, and 5FU+CIT. Mice were fed with commercial chow and supplemented with an oral solution of alanine (control and 5FU groups) or CIT (CIT and 5FU+CIT groups). On the seventh day, mice received intraperitoneal phosphate‐buffered saline or 5FU (200 mg/kg, single dose) to induce mucositis. On the 10th day, mice were euthanized, and the blood and small intestines were harvested. Body weight, morphology, histopathology score (hematoxylin and eosin) of the small intestine (from 0–12), myeloperoxidase activity, oxidative stress level, and intestinal permeability were assessed. Results: We observed significant weight loss after the administration of 5FU in both treated and control animals. CIT administration contributed to a partial recovery of the mucosal architecture as well as an intermediate reduction of the histopathologic score, and functional intestinal permeability was partially rescued. Conclusions: CIT administration attenuated 5FU‐mediated damage to the mucosal architecture of the small intestine, decreasing the size of the injured areas and promoting decreased intestinal permeability.     

Prevalence and impact of urinary incontinence among female athletes

Objective

To assess the prevalence of urinary incontinence (UI) in a group of female athletes and to explore its impact on their lives.

Methods

In total, 106 female athletics, basketball, and indoor football athletes were recruited. Data were collected through a questionnaire and a focus group and analyzed via Pearson's χ² test, 2-way analysis of variance, and thematic analysis.

Results

Urinary incontinence was experienced by 41.5% of the athletes. Its prevalence across the 3 types of sport was similar and was not affected by age. However, athletes who experienced UI had a lower body weight (P = 0.011) and a lower body mass index (P = 0.035). Most (95.5%) athletes had never discussed their condition with a health professional. In the focus group, all athletes described preventive urination to avoid urine leakage. It was mentioned that UI affected their performance and made them feel uncomfortable and frustrated.

Conclusion

Urinary incontinence is a prevalent condition among athletes that is not openly discussed. However, it causes regular changes in their physical performance and daily life. More research is needed to increase awareness of UI and to design interventions.     

Percutaneous image-guided splenic biopsy in the oncology patient: an audit of 156 consecutive cases

PURPOSE: To assess the safety and diagnostic accuracy of percutaneous image-guided splenic biopsy in patients known to have or suspected of having malignancy. MATERIALS AND METHODS: Data from all image-guided splenic biopsies performed at a single institution from January 1992 to March 2007 were retrospectively reviewed. One hundred fifty-six splenic biopsies were performed in 147 patients (78 male and 69 female patients; mean age, 54.9 years; age range, 13-81 years). The most common indications for biopsy were suspected recurrent lymphoma (n = 101, 64.7%), suspected metastatic disease (n = 39, 25%), and unknown diagnosis (n = 16, 10.3%). All biopsies were performed with computed tomographic (n = 86), ultrasonographic (n = 68), or fluoroscopic (n = 2) guidance. Most biopsies (91%) were performed with 22-gauge needles, with a mean of 2.8 passes. The mean lesion size was 3.2 cm (range, 0.8-13 cm). Final diagnosis was confirmed with splenectomy (n = 39), histopathologic correlation with concurrent biopsy or surgical specimen (n = 52), or clinical or imaging follow-up ranging from 2 weeks to 14 years (n = 44). Complications were recorded. RESULTS: Sufficient tissue for pathologic analysis was obtained in 144 of the 156 biopsies (diagnostic yield, 92.3%). The overall sensitivity, specificity, and diagnostic accuracy were 83.4%, 87.8%, and 84.7%, respectively. Complications occurred in 26 biopsies (16.7%), with a 1.9% (n = 3) major complication rate and a 14.7% (n = 23) minor complication rate. Splenectomy was necessary in two patients. CONCLUSIONS: Splenic biopsy in the evaluation of new or recurrent neoplasm is a minimally invasive procedure with low complication rates and a high diagnostic yield.     

Image-Guided Drainage of Pericardial Effusions in Oncology Patients

The purpose of this study was to report our clinical experience with image-guided drainage of pericardial effusions in oncology patients. IRB approval was obtained for this retrospective, HIPAA-compliant study. From November 2002 to January 2008, 40 patients underwent 43 image-guided drainages of pericardial effusions. The medical records were reviewed to analyze the technical aspects of the procedures, complications, and clinical outcomes. Thirty-three pericardial drains were placed and 10 pericardiocenteses were performed. The technical success rate was 100%. Thirty-three procedures were performed under computed tomographic (CT) guidance, five under ultrasound (US) guidance, and five using both CT and US guidance. There were no technical, procedure-related complications. Delayed postprocedure complications and arrhythmias occurred in 11 cases, for an overall complication rate of 25.6%. All complications occurred in patients who had undergone drain placement. Nine patients developed new or worsening arrhythmias and six of these patients required transfer to a higher level of care or the initiation of pharmacological management. In 58.6% of drain placements, including 4 of 11 patients who developed complications, the catheter could have been removed earlier. The median overall survival was 6.47 months (95% CI: 2.37, 12.7). In conclusion, image-guided pericardial drain placement is safe and feasible. Due to the frequency of delayed postprocedure arrhythmias, follow-up monitoring in a telemetry unit is recommended. Prompt catheter removal after drainage may reduce the incidence of delayed post-catheter-insertion arrhythmias.     

Serum tumor markers in colorectal cancer staging,grading, and follow-up

Early diagnosis of colorectal cancer, a frequent neoplasia in industrialized countries, permits curative surgery. In this study we assessed the clinical role of serum tumor markers determination in diagnosing, staging, and grading colorectal cancer; the role of carcinoembryonic antigen (CEA), CA 19-9, tissue polypeptide antigen (TPA) and CA 72-4 in colorectal cancer follow-up was also assessed. In 114 patients with colorectal cancer, the oncofetal antigen CEA was compared with the membrane-associated glycoproteins CA 19-9, CA 242, and CA 72-4 and with the cytokeratins TPA, tissue polypeptide-specific antigen (TPS) and tissue polypeptide monoclonal antigen (TPM). Overall, the most sensitive indices were TPA and TPS (67% and 70%, respectively). Tumor stage influenced the levels of CEA, CA 19-9, and TPA, but not those of TPS, while tumor grade influenced CEA and TPS, but not CA 72-4, TPA, and TPM. TPA was the most sensitive index in identifying early or well-differentiated colorectal cancers. The sensitivity was enhanced when this marker was determined in combination with CEA, in diagnosing both advanced and early colorectal tumors. Seventy-seven patients were followed up after therapy for at least 18 months. CEA was the most sensitive index of recurrence (58%); however, this sensitivity is too low to consider tumor markers useful in colorectal cancer follow-up. © 1996 Wiley-Liss, Inc.     

Approximate entropy of self-reported mood prior to episodes in bipolar disorder

Background:  Approximate entropy (ApEn) measures regularity in time series data, while traditional linear statistics measure variability. Using self-reported mood data from patients with bipolar disorder, this preliminary study addressed whether ApEn could distinguish (i) the 60 days prior to the start of a manic or depressed episode from the 60 days prior to a month of euthymia, and (ii) the 60 days prior to a manic episode from the 60 days prior to a depressed episode.
Methods:  Self-reported mood data from 49 outpatients with bipolar disorder receiving standard treatment were analysed. The data contained 27 episodes (12 manic and 15 depressed), and 43 periods of 1 month of euthymia. For the 60 days prior to episode or euthymia, the ApEn, linear statistics and the correlation between linear and non-linear measures were calculated.
Results:  ApEn was significantly greater in the 60 days prior to a manic or depressive episode than the 60 days prior to a month of euthymia. The onset of an episode was associated with greater irregularity in mood. Variability was also significantly larger and correlated with ApEn. ApEn was significantly greater in the 60 days prior to a manic episode than in the 60 days prior to a depressed episode, whereas measures of variability were not significantly different. Mood in the 60 days prior to mania was more irregular than prior to depression.
Conclusions:  Non-linear measures may complement traditional linear measures in the analysis of longitudinal data in bipolar disorder. A larger study is indicated.
