Does climate impact inflatable penile prosthesis infection (IPP) risk? Assessment of temperature and dew point on IPP infections.

BACKGROUND: Variations in climate have been associated with a greater risk of surgical site infections, urinary tract infections, and changes in the skin microbiome; however, limited data exist on the impact of climate on inflatable penile prosthesis (IPP) infections. AIM: We sought to evaluate the impact of climate on the risk of IPP infections in a large international, multicenter cohort. METHODS: We performed a multi-institutional, retrospective study of patients undergoing IPP surgery. We then evaluated whether the month or season, during which surgery was performed, affected device infections. Implant infections were defined as infections requiring device explantation. A univariate logistic regression analysis was undertaken. OUTCOMES: Our primary outcome was implant infection. RESULTS: A total of 5289 patients with a mean age of 62.2 ± 10.8 years received IPP placement. There was a fairly even distribution of implants performed in each season. A total of 103 (1.9%) infections were recorded. There were 32 (31.1%) IPP infections in patients who underwent surgery in the summer, followed by 28 (27.2%) in the winter, 26 (25.2%) in the spring, and 17 (16.5%) in the fall. No statistically significant differences were recorded in terms of season (P = .19) and month (P = .29). The mean daily temperature (P = .43), dew point (P = .43), and humidity (P = .92) at the time of IPP placement was not associated with infection. CLINICAL IMPLICATIONS: These findings provide reassurance to prosthetic urologists that infection reduction strategies do not need to be tailored to local climate. STRENGTHS AND LIMITATIONS: Climate data were not directly recorded for each hospital, but rather based on the monthly averages in the city where the surgery was performed. CONCLUSION: The climate at time of IPP placement and time of year of surgery is not associated with IPP infection risk.

[Certification by the German Society for Neurorehabiliation, DGNR : Performance and quality of the "Centers for weaning from a ventilator in early neurological and neurosurgical rehabilitation"]. / Zertifizierung der Deutschen Gesellschaft für Neurorehabilitation e. V., DGNR : Leistung und Qualität der "Zentren für Beatmungsentwöhnung in der neurologisch-neurochirurgischen Frührehabilitation".

BACKGROUND: Certification of centers for weaning from a ventilator in neurological neurosurgical early rehabilitation (NNER) by the German Society for Neurorehabilitation (DGNR) is possible since 1 October 2021. OBJECTIVE: The results of certification of facilities in the first year after starting the procedure are presented. MATERIAL AND METHODS: As part of the certification process 28 criteria are assessed including a set of mandatory characteristics of the facility. The criteria are divided into structural criteria (i = 7), diagnostic criteria (i = 6), personnel criteria (i = 3), internal organization criteria (i = 7), and quality management criteria (i = 5). RESULTS: A total of 13 centers were certified in the first year, with a combined total of 283 beds for weaning from a ventilator in the NNER and served 2278 persons to be weaned from a ventilator in the year before certification, with a median of 134 per facility (range 44-414). Only rarely was weaning unsuccessful, requiring conversion to home mechanical ventilation before discharge (invasive home mechanical ventilation median per facility 10 persons, range 2-25; non-invasive home mechanical ventilation median 0 persons, range 0-57). A high level of process and structural quality was documented for the certified centers: across all areas of assessment, the individual certification criteria were met in the vast majority of cases (median degree of complete fulfilment 86%) or met with improvement potentials documented by the auditors (median 11%). CONCLUSION: Successful weaning in NNER and a high level of process and structural quality can be demonstrated by the certification results of centers that follow this integrative approach to weaning from a ventilator in a NNER setting.

AUA-recommended Antibiotic Prophylaxis for Primary Penile Implantation Results in a Higher, Not Lower, Risk for Postoperative Infection: A Multicenter Analysis.

PURPOSE: Our aim was to determine if the AUA-recommended prophylaxis (vancomycin + gentamicin alone) for primary inflatable penile prosthesis surgery is associated with a higher infection risk than nonstandard regimens. MATERIALS AND METHODS: We performed a multicenter, retrospective study of patients undergoing primary inflatable penile prosthesis surgery. Patients were divided into those receiving vancomycin + gentamicin alone and those receiving any other regimen. A Cox proportional-hazards model was constructed adjusted for major predictors. A subgroup analysis to identify the appropriate dosage of gentamicin was also performed. RESULTS: A total of 4,161 patients underwent primary inflatable penile prosthesis placement (2,411 received vancomycin + gentamicin alone and 1,750 received other regimens). The infection rate was similar between groups, 1% vs 1.2% for standard vs nonstandard prophylaxis. In the multivariable analysis, vancomycin + gentamicin (HR: 2.7, 95% CI: 1.4 to 5.4, P = .004) and diabetes (HR: 1.9, 95% CI: 1.03 to 3.4, P = .04) were significantly associated with a higher risk of infection. Antifungals (HR: 0.08, 95% CI: 0.03 to 0.19, P < .001) were associated with lower risk of infection. There was no statistically significant difference in infection rate between weight-based gentamicin compared to 80 mg gentamicin (HR: 2.9, 95% CI: 0.83 to 10, P = .1). CONCLUSIONS: Vancomycin + gentamicin alone for antibiotic prophylaxis for primary inflatable penile prosthesis surgery is associated with a higher infection risk than nonstandard antibiotic regimens while antifungal use is associated with lower infection risk. A critical review of the recommended antimicrobial prophylactic regimens is needed. Prospective research is needed to further elucidate best practices in inflatable penile prosthesis antimicrobial prophylaxis.

Delayed placement of an inflatable penile prosthesis is associated with a high complication rate in men with a history of ischemic priapism.

BACKGROUND: Corporal fibrosis is known to result from prolonged priapism; however, the impact of the timing of penile prosthesis placement after priapism on complication rates is poorly understood. AIM: We sought to evaluate the impact of timing of inflatable penile prosthesis (IPP) placement on complications in men with a history of ischemic priapism. METHODS: We performed a multicenter, retrospective cohort study of patients with a history of priapism undergoing IPP placement by 10 experienced implantation surgeons. We defined early placement as ≤6 months from priapism to IPP. We identified a 1:1 propensity-matched group of men without a history of priapism and compared complication rates between men who had early placement, late placement, and no history of priapism. OUTCOMES: Our primary outcome was postoperative noninfectious complications, and secondary outcomes included intraoperative complications and postoperative infection. RESULTS: A total of 124 men were included in the study with a mean age of 50.3 ± 12.7 years. A total of 62 had a history of priapism and 62 were matched control subjects. The median duration of priapism was 37 (range, 3-168) hours and the median time from ischemic priapism to IPP placement was 15 months (range, 3 days to 23 years). Fifteen (24%) men underwent early (≤6 months) IPP placement at a median time of 2 months (range, 3 days to 6 months) following the ischemic priapism event. The remaining 47 (76%) underwent placement >6 months following priapism at a median time of 31.5 months (range, 7 months to 23 years). The complication rate in the delayed placement group was 40.5% compared with 0% in the early placement group and control group. Cylinder-related complications such as migration or leak accounted for 8 (57%) of 14 of the postoperative noninfectious complications. Full-sized cylinders were used in all patients who had a cylinder related complication. CLINICAL IMPLICATIONS: Priapism patients should be referred to prosthetic experts early to decrease complication rates in those needing an IPP. STRENGTHS AND LIMITATIONS: This is a multicenter study from experienced prosthetic urologists but is limited by the retrospective nature and small number of patients in the early placement group. CONCLUSION: IPP complication rates are high in men with a history of ischemic priapism, especially when implantation is delayed beyond 6 months.

[The Respiratory Therapist in Neurology An Evolving Specialization in Germany]. / Der Atmungstherapeut in der Neurologie ­ Ein Blick auf das Berufsbild und ein Ausblick in die Zukunft.

In Germany, nurses, physiotherapists and speech and language therapists follow a qualifying training for about 1,5 years to become respiratory therapists (RTs). With respect to neurological illness, RTs diagnose and treat disorders of respiration, cough and swallowing as well as a retention of tracheobronchial secretions. There is an increasing demand for RTs in neurology, in neurointensive care and in neurological and neurosurgical early rehabilitation. The certification of specialized centers for weaning in neurological and neurosurgical early rehabilitation was introduced by the German Society for Neurorehabilitation (DGNR) in 2021. As a certification criterion it includes the employment of a respiratory therapists. In neurological organizations treating critically and severely ill patients, RTs work at an important interdisciplinary intersection of physicians, nurses and therapists. RTs are qualified to train teams, patients and family caregivers and to establish care structures for critically and severely ill neurological patients. Due to the complexity of neurological illnesses RTs working in neurological institutions need specific qualification. Specific training for RTs in neurology and neurorehabilitation might improve care for critically and severely ill neurological patients. Further professionalization of RT in Germany requires standardizing curricula, a professional society for RTs and, finally, academization.

Review of Ischemic and Non-ischemic Priapism.

PURPOSE OF REVIEW: Priapism is a rare condition that has different presentations, etiologies, pathophysiology, and treatment algorithms. It can be associated with significant patient distress and sexual dysfunction. We aim to examine the most up-to-date literature and guidelines in the management of this condition. RECENT FINDINGS: Priapism is a challenging condition to manage for urologists, since the etiology is often multi-factorial and the suggested treatment algorithms are based on small studies and expert anecdotal experience, perhaps due to the rarity of the disorder. Ischemic priapism of less than 24 h can be managed non-surgically in most cases with excellent results. Ischemic priapism of more than 36 h is frequently associated with permanent erectile dysfunction. Management of prolonged priapism with penile shunting still may result in poor erectile function, so penile prosthesis can be discussed in these scenarios.

[The certification of centers for weaning from mechanical ventilation in neurological and neurosurgical early rehabilitation by the German Society for Neurorehabilitation]. / Die Zertifizierung von Zentren für Beatmungsentwöhnung in der neurologisch-neurochirurgischen Frührehabilitation durch die Deutsche Gesellschaft für Neurorehabilitation.

Specialized centers for weaning in neurological and neurosurgical early rehabilitation can be certified by the German Society for Neurorehabilitation (DGNR) since 1 October 2021. The certification criteria are indicators for structure and process quality and for treatment results for weaning of neurological patients from mechanical ventilation. In Germany these patients are treated in departments for neurological and neurosurgical early rehabilitation in acute care hospitals as well as in specialized rehabilitation hospitals. Acknowledging this diversity of care, certification is possible for both kinds of institutions. Certification is granted by the DGNR in cooperation with TÜV Rheinland as the certification authority, analogous to the certification of stroke units. Institutions apply for certification by sending all necessary documents to the TÜV Rheinland. Afterwards auditors of the TÜV Rheinland (lead auditor) and the DGNR (medical speciality auditor) visit the institution on site. The results of this visit are reported to the certification committee of the DGNR, which in turn recommends or declines certification. The certification of centers for weaning in neurological and neurosurgical early rehabilitation is an important step towards defining neurorespiratory care and the role of the neurologist for intensive care and weaning in Germany. Thereby, the interdisciplinary dialogue between pneumologists, anesthesiologists, and neurologists is fostered. Also, the dialogue on treatment capacities and strategies with healthcare politicians, health insurances, and patient associations is facilitated.

A Multicenter Investigation Examining American Urological Association Recommended Antibiotic Prophylaxis vs Nonstandard Prophylaxis in Preventing Device Infections in Penile Prosthesis Surgery in Diabetic Patients.

PURPOSE: American Urological Association (AUA) antibiotic prophylaxis recommendations may be insufficient for covering organisms commonly found in penile prosthesis infections. In this study we assess the difference between AUA recommended antibiotic prophylaxis and nonstandard prophylaxis in preventing device infections in penile prosthesis surgery performed in diabetic patients. MATERIALS AND METHODS: A multicenter, retrospective cohort study of diabetic patients undergoing primary penile prosthesis surgery was performed between April 2003 and August 2018. Eighteen institutions from the United States, Europe and Korea contributed. The association between antibiotic prophylaxis type and postoperative penile prosthesis infections, device explantations and revision surgeries was assessed. RESULTS: Standard AUA antibiotic prophylaxis was followed in 48.6% (391) of cases while nonstandard prophylaxis was used in 51.4% (413). Common nonstandard antibiotic prophylaxis included vancomycin-gentamycin-fluoroquinolone, clindamycin-fluoroquinolone, and vancomycin-fluoroquinolone among other combinations. Patients who received AUA prophylaxis had significantly more postoperative device infections (5.6% vs 1.9%, p <0.01) and explantations (8.3% vs 2.0%, p <0.001) compared to those who received nonstandard prophylaxis. Patients who received AUA prophylaxis had significantly higher odds of a postoperative device infection (OR 2.8, 95% CI 1.1-7.3) and explantation (OR 3.6, 95% CI 1.4-9.1) compared to those who received nonstandard prophylaxis. CONCLUSIONS: Diabetic men with erectile dysfunction who received standard AUA prophylaxis for penile prosthesis surgery had significantly greater odds of experiencing a postoperative device infection and device explantation compared to patients who received nonstandard prophylaxis. Our study provides a strong rationale for a prospective investigation to establish the most appropriate prophylaxis strategy in penile prosthesis surgery.

Are We Overstating the Risk of Priapism With Oral Phosphodiesterase Type 5 Inhibitors?

BACKGROUND: Priapism is an adverse drug reaction (ADR) associated with phosphodiesterase type 5 inhibitors (PDE5is) in the treatment of erectile dysfunction. AIM: The purpose of this study was to identify the true data about PDE5i-associated priapism to properly counsel patients. METHODS: We queried the U.S. Food and Drug Administration (FDA) Adverse Reporting System Public Dashboard to identify cases of drug-induced priapism among medications commonly associated with priapism. Next, a systematic review and analysis of publications describing cases of drug-induced priapism were carried out. OUTCOMES: The main outome of this study is incidence of PDE5i-induced priapism. RESULTS: We found 411 cases of drug-induced priapism secondary to Viagra, Cialis, or Levitra reported to the Food and Drug Administration since 1998. Compared with PDE5is, drug-induced priapism was 2.6 (n = 1,065) and 2.0 times (n = 817) more commonly reported for second-generation antipsychotics and the antidepressant/sleep aid trazodone, respectively. A total of 240 manuscripts describing cases of drug-induced priapism in patients with non-sickle cell disease were identified. PDE5i-induced priapism accounted for only 2.9% (n = 7) of drug-induced priapism cases. Second-generation antipsychotics (33.8%), a group of "other" medications (11.3%), and alpha-adrenergic antagonists (8.8%) accounted for the greatest percentage of published drug-induced priapism cases. CLINICAL IMPLICATIONS: Extensive counseling about priapism as an ADR for PDE5i for the routine treatment of erectile dysfunction is likely unnecessary. STRENGTHS & LIMITATIONS: The study used national-level data to identify drug-induced priapism cases. Reported and published cases of drug-induced priapism may reflect more severe and atypical cases of this ADR, which may have underestimated our results. CONCLUSION: PDE5i-induced priapism is a rare event. Drug-induced priapism should be attributed to a wider spectrum of medications that can cause this condition. Rezaee ME, Gross MS.

A Multi-institutional Assessment of Multimodal Analgesia in Penile Implant Recipients Demonstrates Dramatic Reduction in Pain Scores and Narcotic Usage.

INTRODUCTION: Despite the pain associated with inflatable penile prosthesis (IPP) implantation, there has been a lack of standardized, nonopioid pain control regimens described to date. AIM: To assess the effectiveness of a multimodal analgesic regimen in patients undergoing implantation of an IPP compared with patients treated with an opioid-only regimen. METHODS: A large, multicenter patient cohort undergoing IPP implantation whose pain was managed using a multimodal analgesia (MMA) protocol (preoperative and postoperative acetaminophen, meloxicam orcelecoxib, and gabapentin and intraoperative dorsal and pudendal nerve blocks) was compared with a matched cohort of patients managed via an opioid-only protocol. Both groups were compared with respect to visual analog score (VAS) and opioid usage (total morphine equivalents [TME]) in the post-anesthesia care unit (PACU), postoperative day 0 (POD0) and postoperative day 1 (POD1), and in the immediate postdischarge period. Narcotic usage on discharge and follow-up were assessed and compared. MAIN OUTCOME MEASURE: Postoperative pain scores and narcotic usage are the main outcome measures. RESULTS: 203 patients were eligible for final analysis: 103 (50.7%) patients receiving MMA medication and 100 (49.3%) patients receiving opioids only. The VAS was significantly lower in the multimodal group in PACU (median 0.0 vs 2.0, P = .001), POD0 (median 3.0 vs 4.0, P = .001), and POD1 (median 3.0 vs 4.3, P = .04). Patients in the multimodal group also used fewer narcotics in PACU (median 0.0 vs 4.0 TME, P = .001), POD0 (median 7.5 vs 12.5 TME, P < .001), and POD1 (median 7.5 vs 13.5 TME, P = .01). Despite being discharged with fewer narcotics (median 20.0 vs 30.0 tablets, P < .001), a smaller proportion of patients in the MMA cohort required narcotic refills (10.7% vs 28.0%, P = .001). There were no narcotic- or MMA medication-related side effects in the entire cohort. CLINICAL IMPLICATIONS: MMA confers significant improvement in pain management while also providing a significant reduction in narcotic usage in patients undergoing implantation of IPP. STRENGTH & LIMITATIONS: This is the 1st large multi-institutional assessment of a multimodal analgesic regimen in urologic prosthetic surgery. The analgesic regimen targets several pain pathways that provide excellent pain control throughout the recovery process. Limitations include retrospective design and lack of standardization of the nonsteroidal anti-inflammatory drug type within the multimodal analgesic regimen. CONCLUSION: The use of a MMA protocol significantly reduces postoperative pain measures in penile implant recipients and further reduces both inpatient and outpatient narcotic usage without any discernable side effects.

Impact of Antimicrobial Dipping Solutions on Postoperative Infection Rates in Patients With Diabetes Undergoing Primary Insertion of a Coloplast Titan Inflatable Penile Prosthesis.

BACKGROUND: Modern-day penile prostheses use infection retardant coating to decrease rates of postoperative infection, subsequently reducing explantation and revision rates as well. The Coloplast Titan models are dipped into antimicrobial solutions right before implantation, and the components used for dipping can be tailored toward the patient. AIM: To compare infection, explantation, and revision rates among different dipping solutions used before implantation for patients with diabetes receiving a Coloplast Titan implant. METHODS: We systematically reviewed 932 patients with diabetes receiving a primary penile implant across 18 different centers from the period April 2003 to August 2018. Of those patients, 473 received a Coloplast device, whereas 459 received an AMS device. Data regarding the type of antimicrobial solution used before implantation were recorded for 468 patients receiving a Coloplast Titan, including whether or not they suffered a postoperative infection and if they underwent explantation and/or revision. Outcome rates were compared using Fisher's exact and Pearson's chi-square tests, and logistic regression modeling was performed to account for covariates. OUTCOMES: The main outcome measures of this study were postoperative infection, explantation, and revision rates. RESULTS: Of the total 932 patients reviewed, 33 suffered a postoperative infection. Of 468 patients receiving Coloplast implants, there was a 3.4% infection rate. The most commonly used antibiotic combination before dipping was vancomycin + gentamicin (59.0%). There was a significantly lower rate of postoperative infection, explantation, and revision when vancomycin + gentamicin was used than those associated with the use of all other dipping solutions ([1.4% vs 6.4%; P = .004], [1.1% vs 8.3%; P < .001], and [2.5% vs 12.5; P < .001], respectively). After adjusting for age, body mass index, preoperative blood glucose level, and hemoglobin A1c, the use of other dips was an independent predictor of postoperative infection (odds ratio: 0.191; P = .049). The inclusion of rifampin in the dipping solution trended toward being a significant risk factor for infection (P = .057). Including antifungals in the dipping solution did not affect infection (P = .414), explantation (P = .421), or revision (P = .328) rates. CLINICAL IMPLICATIONS: Vancomycin + gentamicin was the most efficacious combination of antibiotics used for dipping in terms of preventing postoperative infection and subsequent explantation and revision. STRENGTHS AND LIMITATIONS: Data were sampled across multiple institutions providing a large sample that may be more representative of the population of interest. A key limitation of the study was its retrospective nature, which prevented us from controlling certain variables. CONCLUSION: The use of rifampin did not provide the same type of protection, possibly representing a shift in resistance patterns of common bacteria responsible for device infection.

[Weaning in neurological and neurosurgical early rehabilitation-Results from the "WennFrüh" study of the German Society for Neurorehabilitation]. / Weaning in der neurologisch-neurochirurgischen Frührehabilitation ­ Ergebnisse der "WennFrüh"-Studie der Deutschen Gesellschaft für Neurorehabilitation.

Neurological and neurosurgical early rehabilitation patients are often so critically ill that they must be weaned from mechanical ventilation in addition to early rehabilitative treatment. The German Society for Neurorehabilitation (DGNR) carried out a survey and asked neurological weaning units to provide information on structural characteristics of the facility, including personnel and technical resources and the number of cases and outcome based on anonymous data. In total 36 weaning units from 11 federal states with a total of 496 beds participated in the survey. From 2516 weaning cases documented in 2019, 2097 (83.3%) could primarily be successfully weaned from mechanical ventilation and only 120 (4.8%) had to be discharged with home ventilation. The mortality in this sample was 11.0% (n = 276). The results of the survey demonstrate that prolonged weaning during early neurological and neurosurgical rehabilitation is an important and effective component of healthcare provision for critically ill patients in Germany.

Radiation protection modelling for 2.5 Petawatt-laser production of ultrashort x-ray, proton and ion bunches: Monte Carlo model of the Munich CALA facility.

The 'Centre for Advanced Laser Applications' (CALA) is a new research institute for laser-based acceleration of electron beams for brilliant x-ray generation, laser-driven sub-nanosecond bunches of protons and heavy ions for biomedical applications like imaging and tumour therapy as well as for nuclear and high-field physics.The radiation sources emerging from experiments using the up to 2.5 petawatt laser pulses with 25 femtosecond duration will be mixed particle-species of high intensity, high energy and pulsed, thus posing new challenges compared to conventional radiation protection. Such worldwide pioneering laser experiments result in source characteristics that require careful a-priori radiation safety simulations.The FLUKA Monte-Carlo code was used to model the five CALA experimental caves, including the corridors, halls and air spaces surrounding the caves. Beams of electrons (<5 GeV), protons (<200 MeV),12C (<400MeV/u) and197Au (<10MeV/u) ions were simulated using spectra, divergences and bunch-charges based on expectations from recent scientific progress.Simulated dose rates locally can exceed 1.5 kSv h-1inside beam dumps. Vacuum pipes in the cave walls for laser transport and extraction channels for the generated x-rays result in small dose leakage to neighboring areas. Secondary neutrons contribute to most of the prompt dose rate outside caves into which the beam is delivered. This secondary radiation component causes non-negligible dose rates to occur behind walls to which large fluences of secondary particles are directed.By employing adequate beam dumps matched to beam-divergence, magnets, passive shielding and laser pulse repetition limits, average dose rates in- and outside the experimental building stay below design specifications (<0.5µSv h-1) for unclassified areas,<2.5µSv h-1for supervised areas,<7.5µSv h-1maximum local dose rate) and regulatory limits (<1mSv a-1for unclassified areas).

Hypersalivation: update of the German S2k guideline (AWMF) in short form.

Hypersalivation describes a relatively excessive salivary flow, which wets the patient himself and his surroundings. It may result because of insufficient oro-motor function, dysphagia, decreased central control and coordination. This update presents recent changes and innovation in the treatment of hypersalivation. Multidisciplinary diagnostic and treatment evaluation is recommended already at early stage and focus on dysphagia, saliva aspiration, and oro-motor deficiencies. Clinical screening tools and diagnostics such as fiberoptic endoscopic evaluation of swallowing generate important data on therapy selection and control. Many cases profit from swallowing therapy programmes to activate compensation mechanisms as long compliances are given. In children with hypotonic oral muscles, oral stimulation plates can induce a relevant symptom release because of the improved lip closure. The pharmacologic treatment improved for pediatric cases as glycopyrrolate fluid solution (Sialanar®) is now indicated for hypersalivation within the EU. The injection of botulinum toxin into the salivary glands has shown safe and effective results with long-lasting saliva reduction. Here, a phase III trial is completed for incobotulinum toxin A and, in the US, is indicated for the treatment of adult patients with chronic hypersalivation. Surgical treatment should be reserved for isolated cases. External radiation is judged as a safe and effective therapy when using modern 3D techniques to minimize tissue damage. Therapy effects and symptom severity have to be followed, especially in cases with underlying neurodegenerative disease.

The Use of Antiseptic Solutions in the Prevention and Management of Penile Prosthesis Infections: A Review of the Cytotoxic and Microbiological Effects of Common Irrigation Solutions.

INTRODUCTION: The Mulcahy salvage fundamentally altered the management of penile prosthesis infections (PPI). Central to this procedure is a sequence of antiseptic irrigations that aims to remove and eradicate pathogenic microflora from the infected field, thus preparing for immediate reimplantation. The antiseptic solutions and their respective concentrations, however, have never been evaluated for efficacy. AIM: This review critically examines 3 commonly used antiseptic irrigation solutions (povidone-iodine [PVI], hydrogen peroxide [H2O2], and chlorhexidine gluconate [CHG]) in terms of their antimicrobial activity, cytotoxicity, and clinical use. METHODS: A PubMed literature review was performed on articles published between 2003 and 2018. Both preclinical as well as clinical studies from various surgical disciplines were included in this review. MAIN OUTCOME MEASURE: The original salvage protocol selected for irrigation solutions at concentrations that are likely detrimental to native tissue. RESULTS: All 3 agents demonstrate in vitro cytotoxic effects at subclinical concentrations, but H2O2 is associated with the most significant deleterious properties. It does not seem to broaden antimicrobial coverage beyond what is covered by PVI. Dilute PVI (0.35-3.5% with exposure time of at least 3 minutes) possesses the most robust clinical evidence as an intraoperative adjunct, reducing the incidence of postoperative infectious complications. chlorhexidine gluconate is a promising new agent but lacks clinical data. CLINICAL IMPLICATION: Improvements in the salvage protocol are warranted based on current evidence. Careful selection of lavage solution and usage of the lowest necessary concentration will help achieve desired antimicrobial activity while avoiding native tissue cytotoxicity. Strength and limitation: The study is limited by its retrospective nature, and the heterogeneity of literature reviewed precluded a formal meta-analysis. Furthermore, future studies will need to address the roles of normal saline and antibiotic irrigations as intraoperative adjuncts for infection prevention. CONCLUSION: Diluted PVI (0.35-3.5% for 3 minutes) may be beneficial in the prevention of PPI. Evidence supports its use both in the setting of primary implantation as well as salvage of infected hardware. An improved, evidence-based protocol may increase positive outcomes of urologic prosthetic surgery. Pan S, Rodriguez D, Thirumavalavan N, et al.

Multicenter Investigation of Fungal Infections of Inflatable Penile Prostheses.

BACKGROUND: Fungal infections of inflatable penile prostheses (IPPs) are inadequately understood in the literature. AIM: To review a multi-institution database of IPP infections to examine for common patient and surgical factors related to IPP fungal infections. METHODS: This is a retrospective Institutional Review Board-approved analysis of 217 patients at 26 institutions who underwent salvage or device explant between 2001 and 2018. Patient data were compiled after an extensive record review. OUTCOMES: 26 patients (12%) with fungal infections were identified. RESULTS: 23 of 26 patients (83%) with a fungal IPP infection were either diabetic or overweight. 15 patients had undergone primary IPP implantation, and the other 11 had previously undergone an average of 1.7 IPP-related surgeries (range 1-3; median 2). The average age at implantation was 63 years (range 31-92; median 63). 18 of the 26 patients with fungal infection had diabetes (69%), with a mean hemoglobin A1c (HbA1c) value of 8.4 (range 5.8-13.3; median 7.5). Twenty-two patients (85%) were overweight or obese. The mean body mass index for all patients was 30.1 kg/m2 (range 23.7-45 kg/m2; median 28.4 kg/m2), and that for diabetic patients was 30.8 kg/m2 (range 24.1-45 kg/m2, median 29.7 kg/m2). Ninety-one percent of implants were placed with intravenous antibiotics, consistent with current American Urological Association guidelines: an aminoglycoside plus first- or second-generation cephalosporin or vancomycin or ampicillin/sulbactam or piperacillin/tazobactam. 65% (17 of 26) of infected IPPs had only fungal growth in culture. No patient had concomitant immunosuppressive disease or recent antibiotic exposure before IPP implantation. CLINICAL IMPLICATIONS: More than two-thirds of the fungal infections occurred in diabetic patients and 85% occurred in overweight or obese patients, suggesting that antifungal prophylaxis may be appropriate in these patients. STRENGTHS & LIMITATIONS: This is the largest series of fungal infections reported to date in the penile prosthesis literature. The overall number of such cases, however, remains small. CONCLUSION: Fungal infections represent 12% of all penile prosthesis infections in our series and were seen mostly in diabetic or overweight patients, who may benefit from antifungal prophylaxis.

Infection Prevention Considerations for Complex Penile Prosthesis Recipients.

PURPOSE OF REVIEW: The purpose of this review is to critically analyze and summarize recent studies in the area of penile prosthesis surgery outcomes with a focus on infection prevention in high-risk patients. RECENT FINDINGS: Reduction of surgical time in complex prosthesis surgery may reduce infection risk. Concomitant implant surgery is not associated with increased infection risk. Certain immunocompromised patients may be more likely to have penile implant infections, but these may not include patients with well-controlled HIV, well-controlled diabetes, or transplant recipients. Substance abuse is correlated with increased risk of infection after penile implant surgery. Careful patient selection and preoperative optimization can reduce infection risk in spinal cord injury patients. In the last 5 years, there have been several important studies investigating the risk of penile prosthesis infection in complex patients, clarifying which patient categories are at increased risk and how that risk can be mitigated.

BACKGROUND: Mechanical ventilation is provided for neurological patients in the following settings: in neurointensive care units, in centers providing weaning and early rehabilitation and in home mechanical ventilation. In the last decade there has been a sharp rise in treatment and bed capacities for mechanically ventilated neurological patients in specialized centers in Germany in the areas of weaning and neurological neurosurgical early rehabilitation of ventilated patients. Neither the number of beds nor details about structures in these centers with respect to bed capacity, personnel and qualifications, equipment, treatment methods and concepts are known. OBJECTIVE: The aim of this survey was to generate detailed numbers regarding structural criteria of specialized centers for mechanically ventilated neurology patients, regarding hospital beds, technical infrastructure, personnel and qualifications as well as treatment methods and concepts. MATERIAL AND METHODS: An online survey with 48 questions on the type and size of the institution, structural criteria, equipment and personnel was developed and supported by the German Society for Neurology (DGN), the German Interdisciplinary Society of Out-of-Hospital Ventilation (DIGAB) and the German Society of Neurorehabilitation (DGNR). RESULTS: A total of 63 centers took part in the survey and reported a total of 687 beds for mechanically ventilated neurological patients. Furthermore, they reported complex structures regarding personnel and qualifications, medical devices, methods and concepts but neurophysiological electrophysiology was the only technical method provided in all centers. Of the institutions 49% (n = 27/55) provided the initiation of home mechanical ventilation, 18% (n = 18/55) provided inpatient control of home mechanical ventilation, 9% (n = 5/55) had an outpatient department for home mechanical ventilation and 18% (n = 10/55) extracted data from home ventilators. CONCLUSION: Mechanical ventilation in neurological units offers vast and complex treatment and bed capacities for severely ill patients in Germany. The structures are inhomogeneous and a consensus on specific criteria should be established. This is especially true for the treatment of patients needing out-of-hospital mechanical ventilation, also with respect to a possible weaning in the long-term duration of the disease.

[Hypersalivation - Update of the S2k guideline (AWMF) in short form]. / Hypersalivation ­ Aktualisierung der S2k-Leitlinie (AWMF) in gekürzter Darstellung.

Hypersalivation describes a relatively excessive salivary flow, which wets the patient himself and his surroundings. It may result because of insufficient oro-motor function, dysphagia, decreased central control and coordination. This update presents recent changes and innovation in the treatment of hypersalivation.Multidisciplinary diagnostic and treatment evaluation is recommended already at early stage and focus on dysphagia, saliva aspiration, and oro-motor deficiencies. Clinical screening tools and diagnostics such as fiberoptic endoscopic evaluation of swallowing generate important data on therapy selection and control. Many cases profit from swallowing therapy programmes in order to activate compensation mechanisms as long compliances is given. In children with hypotonic oral muscles, oral stimulation plates can induce a relevant symptom release because of the improved lip closure. The pharmacologic treatment improved for pediatric cases as glycopyrrolate fluid solution (Sialanar®) is now indicated for hypersalivation within the E. U. The injection of botulinum toxin into the salivary glands has shown safe and effective results with long lasting saliva reduction. Here, a phase III trial is completed for Incobotulinum toxin A and, in the U. S., is indicated for the treatment of adult patients with chronic hypersalivation. Surgical treatment should be reserved for isolated cases. External radiation is judged as a safe and effective therapy when using modern 3 D techniques to minimize tissue damage. Therapy effects and symptom severity has to be followed, especially in cases with underlying neurodegenerative disease.
