Ciprofloxacin-Resistant Bacteria on Pre-Prostate Biopsy Rectal Swab Culture: A Northwest Ohio Study.

BACKGROUND: Ciprofloxacin is given to patients routinely prior to trans-rectal prostate biopsy. However bacterial resistance to this antibiotic has increased nationally resulting in increased infectious complications after prostate biopsy. In our study we aimed to quantify the percentage of older northwestern Ohio males harboring ciprofloxacin-resistant bacteria in the rectal vault and to assess if resistance is increasing over time. METHODS: After Institutional Review Board approval, a retrospective chart review of all patients who underwent rectal swab culture within the Department of Urology at The University of Toledo Medical Center between January 1, 2012 and December 31, 2015 was completed. Patient demographic data were collected including the presence of ciprofloxacin resistance bacteria. To test for significant differences, χ2 and analysis of variance (ANOVA) analyses were completed where applicable. RESULTS: During the study period 311 swabs for resistant organisms were completed. The average age at time of swab was 64 (± 8.7 standard deviation [SD]) years old. Resistance rates were 13.2%, 13.8%, 19.5%, and 13.3% in 2012, 2013, 2014, and 2015, respectively. We found no statistically significant difference in resistances across years. Additionally, previous biopsy and age were not associated with ciprofloxacin resistance. CONCLUSIONS: Resistance to ciprofloxacin in the rectal vaults of older northwestern Ohio males is significant but appears to be stable over the study period. Previous biopsy and increased age do not appear to be risk factors for fluoroquinolone resistance. Given the relatively high rate of resistance in our population we recommend rectal swabs prior to prostate biopsy to assist in antibiotic agent choice.

Clinical Presentation and Prognosis of Common Movement Disorders.

Great progress has been made in expanding our understanding of the natural history of movement disorders, leading to impressive advancements in their medical and surgical management. Movement disorders are a diverse group of diseases, varying widely in clinical characteristics and evolution. Some are monosymptomatic while others have associated motor and nonmotor features. Some are static while others follow a progressive course. This chapter will review common primary and secondary movement disorders: Parkinson disease and other forms of Parkinsonism, essential tremor and its differential diagnoses, dystonia and tic disorders. Herein, we will provide an overview of the clinical presentation and prognosis of the primary and secondary movement disorders most relevant to discussions of surgical candidacy.

Effect of High-Intensity Treadmill Exercise on Motor Symptoms in Patients With De Novo Parkinson Disease: A Phase 2 Randomized Clinical Trial.

Importance: Parkinson disease is a progressive neurologic disorder. Limited evidence suggests endurance exercise modifies disease severity, particularly high-intensity exercise. Objectives: To examine the feasibility and safety of high-intensity treadmill exercise in patients with de novo Parkinson disease who are not taking medication and whether the effect on motor symptoms warrants a phase 3 trial. Design, Setting, and Participants: The Study in Parkinson Disease of Exercise (SPARX) was a phase 2, multicenter randomized clinical trial with 3 groups and masked assessors. Individuals from outpatient and community-based clinics were enrolled from May 1, 2012, through November 30, 2015, with the primary end point at 6 months. Individuals with idiopathic Parkinson disease (Hoehn and Yahr stages 1 or 2) aged 40 to 80 years within 5 years of diagnosis who were not exercising at moderate intensity greater than 3 times per week and not expected to need dopaminergic medication within 6 months participated in this study. A total of 384 volunteers were screened by telephone; 128 were randomly assigned to 1 of 3 groups (high-intensity exercise, moderate-intensity exercise, or control). Interventions: High-intensity treadmill exercise (4 days per week, 80%-85% maximum heart rate [n = 43]), moderate-intensity treadmill exercise (4 days per week, 60%-65% maximum heart rate [n = 45]), or wait-list control (n = 40) for 6 months. Main Outcomes and Measures: Feasibility measures were adherence to prescribed heart rate and exercise frequency of 3 days per week and safety. The clinical outcome was 6-month change in Unified Parkinson's Disease Rating Scale motor score. Results: A total of 128 patients were included in the study (mean [SD] age, 64 [9] years; age range, 40-80 years; 73 [57.0%] male; and 108 [84.4%] non-Hispanic white). Exercise rates were 2.8 (95% CI, 2.4-3.2) days per week at 80.2% (95% CI, 78.8%-81.7%) maximum heart rate in the high-intensity group and 3.2 (95% CI, 2.8-3.6; P = .13) days per week at 65.9% (95% CI, 64.2%-67.7%) maximum heart rate in the moderate-intensity group (P < .001). The mean change in Unified Parkinson's Disease Rating Scale motor score in the high-intensity group was 0.3 (95% CI, -1.7 to 2.3) compared with 3.2 (95% CI, 1.4 to 5.1) in the usual care group (P = .03). The high-intensity group, but not the moderate-intensity group, reached the predefined nonfutility threshold compared with the control group. Anticipated adverse musculoskeletal events were not severe. Conclusions and Relevance: High-intensity treadmill exercise may be feasible and prescribed safely for patients with Parkinson disease. An efficacy trial is warranted to determine whether high-intensity treadmill exercise produces meaningful clinical benefits in de novo Parkinson disease.

Olfaction and incident Parkinson disease in US white and black older adults.

OBJECTIVE: To investigate olfaction in relation to incident Parkinson disease (PD) in US white and black older adults. METHODS: The study included 1,510 white (mean age 75.6 years) and 952 black (75.4 years) participants of the Health, Aging, and Body Composition study. We evaluated the olfaction of study participants with the Brief Smell Identification Test (BSIT) in 1999-2000. We retrospectively adjudicated PD cases identified through August 31, 2012, using multiple data sources. We used multivariable Cox models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: During an average of 9.8 years of follow-up, we identified a total of 42 incident PD cases, including 30 white and 12 black participants. Overall, poor sense of smell, as indicated by a lower BSIT score, was associated with higher risk of PD. Compared with the highest tertile of BSIT (t3), the HR was 1.3 (95% CI 0.5-3.6) for the second tertile (t2) and 4.8 (95% CI 2.0-11.2) for the lowest tertile (t1) (ptrend < 0.00001). Further analyses revealed significant associations for incident PD in both the first 5 years of follow-up (HRt1/[t2+t3] 4.2, 95% CI 1.7-10.8) and thereafter (HRt1/[t2+t3] 4.1, 95% CI 1.7-9.8). This association appeared to be stronger in white (HRt1/[t2+t3] 4.9, 95% CI 2.3-10.5) than in black participants (HRt1/[t2+t3] 2.5, 95% CI 0.8-8.1), and in men (HRt1/[t2+t3] 5.4, 95% CI 2.3-12.9) than in women (HRt1/[t2+t3] 2.9, 95% CI 1.1-7.8). CONCLUSIONS: Poor olfaction predicts PD in short and intermediate terms; the possibility of stronger associations among men and white participants warrants further investigation.

Same-Day Discharge for Laparoscopic Donor Nephrectomy.

INTRODUCTION: Laparoscopic donor nephrectomy has provided advantages of decreased postoperative pain and length of stay when compared to the open approach. We provide our results of same-day discharge for laparoscopic donor nephrectomy. CASE PRESENTATION: We examined the safety and efficacy of same-day discharge for laparoscopic donor nephrectomy in a retrospective cohort analysis. This institutional review board-approved study began in July 2015, when all consecutive patients who underwent laparoscopic donor nephrectomy were offered same-day discharge. Experimental and control groups were analyzed for differences in sex, age, body mass index, surgery time, estimated blood loss, procedure, complications, length of stay, and distance lived from hospital. Statistical analyses were completed with Mann-Whitney U or Fisher's exact test, as appropriate. MANAGEMENT AND OUTCOME: Eight patients underwent laparoscopic donor nephrectomy during the study period. Of the 8 donors, 4 were discharged on the same day as surgery. The other 4 were discharged the following day. No significant differences were found between the 2 groups with respect to the aforementioned variables. At a median follow-up of 206 days, no complications have been reported. DISCUSSION: The results of our pilot study revealed that same-day discharge is safe and feasible, could have a significant impact on patient satisfaction and healthcare costs, and warrants further study.

Factors Associated With Ambulatory Activity in De Novo Parkinson Disease.

BACKGROUND AND PURPOSE: Objective ambulatory activity during daily living has not been characterized for people with Parkinson disease prior to initiation of dopaminergic medication. Our goal was to characterize ambulatory activity based on average daily step count and examine determinants of step count in nonexercising people with de novo Parkinson disease. METHODS: We analyzed baseline data from a randomized controlled trial, which excluded people performing regular endurance exercise. Of 128 eligible participants (mean ± SD = 64.3 ± 8.6 years), 113 had complete accelerometer data, which were used to determine daily step count. Multiple linear regression was used to identify factors associated with average daily step count over 10 days. Candidate explanatory variable categories were (1) demographics/anthropometrics, (2) Parkinson disease characteristics, (3) motor symptom severity, (4) nonmotor and behavioral characteristics, (5) comorbidities, and (6) cardiorespiratory fitness. RESULTS: Average daily step count was 5362 ± 2890 steps per day. Five factors explained 24% of daily step count variability, with higher step count associated with higher cardiorespiratory fitness (10%), no fear/worry of falling (5%), lower motor severity examination score (4%), more recent time since Parkinson disease diagnosis (3%), and the presence of a cardiovascular condition (2%). DISCUSSION AND CONCLUSIONS: Daily step count in nonexercising people recruited for this intervention trial with de novo Parkinson disease approached sedentary lifestyle levels. Further study is warranted for elucidating factors explaining ambulatory activity, particularly cardiorespiratory fitness, and fear/worry of falling. Clinicians should consider the costs and benefits of exercise and activity behavior interventions immediately after diagnosis of Parkinson disease to attenuate the health consequences of low daily step count.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A170).

Same-Day Discharge for Patients Undergoing Robot-Assisted Laparoscopic Radical Prostatectomy Is Safe and Feasible: Results of a Pilot Study.

INTRODUCTION: With healthcare reform, cost and patient satisfaction will directly affect hospital reimbursement. We present data on same-day discharge (SDD) for patients who underwent robot-assisted laparoscopic radical prostatectomy (RALP). METHODS: Patient data were gathered in an IRB-approved database. In April 2015, the surgeon (S.J.) began SDD. The SDD protocol for RALP includes multimodal anesthesia/analgesia and extended recovery. Interim analysis revealed that government insurance (CMS) refused hospital reimbursement for SDD. As of that time, only patients with commercial insurance were offered SDD. The demographic and peri-operative data were compared between the two cohorts (Group 1, SDD; Group 2, Admitted patients) by using Mann-Whitney U, chi-squared, or fisher exact tests, where appropriate. RESULTS: During the study period, 21 patients had undergone RALP. Eleven of 21 patients were offered SDS, and nine (81.8%) were discharged. Both those who elected to stay were successfully discharged on the next day. Patient age, body mass index (BMI), prostate-specific antigen, operative time, estimated blood loss (EBL), prostate weight, distance from home to hospital, margin status, marital status, and household income were not statistically significantly different between the two groups. The same is true between patients who underwent RALP both before and after initiation of the SDD protocol with the exception of EBL (greater in the SDD group). There have been no reported complications or readmissions for any of the patients in Group 1. CONCLUSION: Our novel pilot study reveals that SDS is safe and feasible. We are currently conducting a further evaluation of patient satisfaction. Future research is needed to verify these conclusions.

Patterns of Motor and Non-Motor Features in Medication-Naïve Parkinsonism.

BACKGROUND: Parkinsonism is defined by motor features (tremor, bradykinesia, rigidity, and postural instability). Accompanying non-motor features (e.g. cognitive, autonomic, sleep disturbances) are underrecognized and undertreated. We hypothesized that clinical patterns occurring in early, medication-naïve Parkinsonism are distinguished by features such as tremor, sleep, autonomic, and cognitive dysfunction. METHODS: Clinical and neuroimaging data were obtained in the Parkinson's Progression Marker Initiative. Group comparisons of Parkinsonism with dopaminergic deficits (PDD) (n = 388), controls (n = 196), and Parkinsonism with scans without evidence of dopaminergic deficits (n = 64) were done with ANOVA, chi-square, and post-hoc pairwise tests. To examine clinical patterns within the PDD group, k-means clustering was performed with non-motor or motor features, or both. RESULTS: Among PDD, 4 non-motor patterns (% of PDD) (impulsive (14.9%), sleep-autonomic (22.9%), cognitive-olfactory (18.0%), and mild (44.1%)), 4 motor patterns (tremor plus bradykinesia (56.2%), tremor without bradykinesia (16.2%), postural instability (6.7%) and no tremor (20.9%)) and 5 combined motor/non-motor patterns (tremor with bradykinesia (42.3%), tremor without bradykinesia (15.5%), no tremor and mild non-motor features (17.0%), postural instability with sleep-autonomic disturbances (6.7%) and oldest onset cognitive-olfactory (18.6%)) were observed. CONCLUSIONS: To our knowledge, this is the first description of non-motor clinical patterns in early, medication-naïve Parkinsonism, suggesting that such features are intrinsic to Parkinsonian disorders.

Validation of secondary data sources to identify Parkinson disease against clinical diagnostic criteria.

Parkinson disease (PD) is the second most common neurodegenerative disorder. Its diagnosis relies solely on a clinical examination and is not straightforward because no diagnostic test exists. Large, population-based, prospective cohort studies designed to examine other outcomes that are more common than PD might provide cost-efficient alternatives for studying the disease. However, most cohort studies have not implemented rigorous systematic screening for PD. A majority of epidemiologic studies that utilize population-based prospective designs rely on secondary data sources to identify PD cases. Direct validation of these secondary sources against clinical diagnostic criteria is lacking. The Framingham Heart Study has prospectively screened and evaluated participants for PD based on clinical diagnostic criteria. We assessed the predictive value of secondary sources for PD identification relative to clinical diagnostic criteria in the Framingham Heart Study (2001-2012). We found positive predictive values of 1.0 (95% confidence interval: 0.868, 1.0), 1.0 (95% confidence interval: 0.839, 1.0), and 0.50 (95% confidence interval: 0.307, 0.694) for PD identified from self-report, use of antiparkinsonian medications, and Medicare claims, respectively. The negative predictive values were all higher than 0.99. Our results highlight the limitations of using only Medicare claims data and suggest that population-based cohorts may be utilized for the study of PD determined via self-report or medication inventories while preserving a high degree of confidence in the validity of PD case identification.

A penal problem: the increasing incidence of implantation of penile foreign bodies.

Our objective is to describe a novel presentation of subcutaneous penile insertion of foreign bodies. This is a practice performed globally and mostly has been reported outside of the United States. We present three cases of incarcerated males that implanted sculpted dominos into the penile subcutaneous tissue. The patients presented with erosion of the foreign bodies through the skin without evidence of infection. We believe that insertion of foreign bodies into penile subcutaneous tissue by incarcerated American males for sexual enhancement is more widespread than previously reported. Erosion is a novel presentation.

Enhancing case ascertainment of Parkinson's disease using Medicare claims data in a population-based cohort: the Cardiovascular Health Study.

PURPOSE: We sought to improve a previous algorithm to ascertain Parkinson's disease (PD) in the Cardiovascular Health Study by incorporating additional data from Medicare outpatient claims. We compared our results to the previous algorithm in terms of baseline prevalence and incidence of PD, as well as associations with baseline smoking characteristics. METHODS: Our original case ascertainment used self-reported diagnosis, antiparkinsonian medication, and hospitalization discharge International Classification of Diseases-Ninth version code. In this study, we incorporated additional data from fee-for-service Medicare claims, extended follow-up time, review of hospitalization records, and adjudicated cause of death. Two movement disorders specialists adjudicated final PD status. We used logistic regression models and controlled for age, sex, African American race, and education. RESULTS: We identified 75 additional cases but reclassified 80 previously identified cases as not having PD. We observed significant inverse association with smoking status (odds ratio = 0.42; 95% confidence interval (CI) = 0.22, 0.79), and inverse linear trends with pack-years (p = 0.005), and cigarettes per day (p = 0.019) with incident PD. All estimates were stronger than those from the previous algorithm. CONCLUSIONS: Our enhanced method did not alter prevalence and incidence estimates compared with our previous algorithm. However, our enhanced method provided stronger estimates of association, potentially due to reduced level of disease misclassification.

A Domino Effect? The Spread of Implantation of Penile Foreign Bodies in the Prison System.

Subcutaneous penile insertion of foreign bodies is a practice performed globally but has mostly been reported outside of the United States. An incarcerated 29-year-old Caucasian male in a midwestern prison whittled a domino into a dog bone shape and placed it into his ventral penile subcutaneous tissue. He presented to our facility with erosion of the corners of the foreign body through his skin without evidence of infection. Self-insertion of foreign bodies into penile subcutaneous tissue by incarcerated American men for sexual enhancement is more widespread than previously reported. Erosion is a novel presentation.

Perceptions of a Videogame-Based Dance Exercise Program Among Individuals with Parkinson's Disease.

OBJECTIVE: Physical therapy, including exercise, improves gait and quality of life in Parkinson's disease (PD). Many programs promoting physical activity have generated significant short-term gains, but adherence has been a problem. A recent evidence-based analysis of clinical trials using physical therapy in PD patients produced four key treatment recommendations: cognitive movement strategies, physical capacity, balance training, and cueing. We have attempted to incorporate all four of these features together through a dance exercise program using the dance videogame "Dance Dance Revolution" (DDR) (Konami Digital Entertainment, El Segundo, CA). SUBJECTS AND METHODS: Sixteen medically stable participants with mild to moderate PD were given the opportunity to try DDR with supervision by a research staff member. Feedback about the advantages and disadvantages of DDR as a form of physical activity was elicited through focus groups using the nominal group technique. RESULTS: Of 21 advantages and 17 disadvantages elicited, the most frequently cited advantages were "fun" and "easy to use," followed by "improves balance or coordination," "challenging," and "full body aerobic activity." Common concerns were the distracting or confusing interface, cost, and possible technical issues. DISCUSSION: Interactive dance exercise was appealing to participants with PD and may help promote adherence to physical activity. Concerns regarding familiarity with the technology may be addressed with simplification of the interface or additional training for participants. Results support a larger longitudinal study of DDR in PD.

Robot-assisted laparoscopic partial nephrectomy for recurrent renal-cell carcinoma in patients previously treated with nephron-sparing surgery.

BACKGROUND AND PURPOSE: With the advent of robotics, it may be more feasible to offer minimally invasive nerve-sparing surgery (NSS), in the form of partial nephrectomy (PN), for patients with metachronous recurrence in the ipsilateral kidney after previous NSS. We studied the outcomes of patients undergoing robot-assisted laparoscopic partial nephrectomy (RAPN) after previous ipsilateral open or laparoscopic NSS for renal-cell carcinoma. METHODS: In this Institutional Review Board approved study, a prospectively maintained PN database was reviewed. Of 230 RAPNs performed between 2003 and 2011, five patients underwent RAPN after previous ipsilateral NSS. RESULTS: The mean age was 64.2 years, and time between the first and second surgery was 27 months (range 9-60 mos). All patients were men and previously had open (n=4) or laparoscopic (n=1) NSS for clear-cell (n=2), papillary (n=2), and other (n=1) pathology. Average follow-up was 15.6 months (range 8-21 mos). There were no conversions to open surgery or radical nephrectomy. Total and selective arterial clamping were performed in two and two cases, respectively. One RAPN was performed off-clamp. Mean warm ischemia time was 14 minutes (range 0-32 min), and mean blood loss was 220 mL (range 50-400 mL). Average length of stay was 1.4 days (range 1-2 days) with no perioperative complications. The glomerular filtration rate decreased by a mean of 10%. There were no recurrences detected on cross-sectional imaging at the most recent follow-up. CONCLUSION: RAPN after previous open or laparoscopic PN is safe and efficacious. It offers satisfactory intermediate functional and oncologic outcomes with minimal morbidity.
