Subgroup Analysis of Overall Survival among Smoking and Non-Smoking Elderly Patients with HNSCC.

Smoking is a leading cause of head and neck squamous cell carcinoma (HNSCC). However, non-smokers are also affected by HNSCC, and the prognostic factors applicable to older non-smokers with HNSCC are largely unknown. The aim of this study was to determine predictors of overall survival (OS) in patients both with and without a smoking history aged 70 and over at initial diagnosis. Retrospective data of patients aged ≥70 (initial diagnoses 2004-2018) were examined. Evaluated predictors included tumour stage, biological age, health and therapy. A total of 688 patients (520 smokers, 168 non-smokers) were included with a median age of 74. The 5-year OS was 39.6%. Non-smokers had significantly improved OS compared to smokers (52.0% versus 36.0%, p < 0.001). Disease-free survival (DFS) differed significantly between both groups (hazard ratio = 1.3; 95%CI 1.04-1.626). TNM stage and the recommended therapies (curative versus palliative) were comparable. The proportion of p16-positive oropharyngeal carcinomas was significantly higher in non-smokers (76.7% versus 43.8%, p < 0.001). Smokers were significantly more likely to be men (p < 0.001), drinkers (p < 0.001), and have poorer health status (Karnofsky performance status, KPS, p = 0.023). They were also more likely to have additional tumours (p = 0.012) and lower treatment adherence (p = 0.038). Important predictors of OS identified in both groups, were, among others, alcohol abuse, KPS, Charlson comorbidity index, site of primary tumour, UICC stage and treatment received. Elderly non-smokers are also affected by HNSCC, however, both OS and DFS are increased compared to smokers.

Depression and anxiety in patients with uveal melanoma undergoing curative proton treatment-A prospective study.

OBJECTIVE: We prospectively addressed whether patient characteristics, oncological outcomes, or metastatic risk impacted depression and anxiety in patients undergoing curative proton treatment for uveal melanoma (UM). METHODS: We assessed patient-reported outcomes regarding anxiety (GAD-7) before and 2 years after proton therapy and depression (PHQ-9) before, 1, and 2 years after proton therapy. We performed descriptive statistics and used linear mixed effect modeling to analyze how the oncological outcome and baseline characteristics impacted anxiety and depression scores. RESULTS: Of 130 (65 female) patients included, six developed metastatic disease and three died during the 2-year follow-up. The mean anxiety declined from 5.86 (SE = 0.56) at baseline to 3.74 (SE = 0.46) at 2 years (ß = 2.11; SE = 0.6; p < .001). Depressive symptoms decreased moderately from 4.36 (SE = 0.37) at baseline to 3.67 (SE = 0.38) 2 years later. Patients with unfavorable metastatic risk or disease progression had elevated anxiety and depression scores. Although female patients reported overall higher anxiety scores, both sexes recovered substantially and to a similar extent during the 2-year follow-up (ß = 2.35; SE 0.87; p = .007 vs. ß = 1.88; SE = 0.60; p = .002). A trend for prolonged depressive symptoms was observed in patients living alone compared to patients living with family members 1 year after the treatment (M = 5.04 [SE = 0.85] vs. M = 3.73 [SE = 0.31], ß = 1.32; SE = 0.92; p = .152). Patients with high baseline anxiety levels showed initially more severe depressive symptoms, which improved significantly during follow-up (ß = 1.65; SE = 0.68; p = .017). CONCLUSION: Most patients undergoing proton therapy for UM experienced mild, transient depressive symptoms and anxiety. Patients with high pre-treatment anxiety, unfavorable prognoses, and patients living alone may be more vulnerable to prolonged depressive symptoms. To these patients a more tailored support could be offered at an early stage of the disease.

Diagnosis of female urethral diverticulum using pelvic floor ultrasound and comparison with voiding cystourethrogram (imaging study).

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to evaluate the sensitivity and specificity of pelvic floor ultrasound (PFUS) in the diagnostic work-up of female urethral diverticulum (UD) and to compare results of PFUS with voiding cystourethrogram (VCUG). METHODS: We retrospectively reviewed our database of patients, who received VCUG and PFUS for the diagnosis of UD. A total of 196 consecutive female patients with a minimum of one symptom, such as a lower urinary tract symptom (LUTS), postmicturition dribble, dyspareunia and recurrent urinary tract infection (UTI) who underwent initial diagnostics with VCUG and PFUS were selected. Diagnostic performance of both procedures, which included size, complexity, echogenicity. and content were compared. RESULTS: Recurrent UTI and LUTS were the most common symptoms, which were present in 165 (84%) and 163 patients (83%) respectively. Final diagnosis of UD was based on PFUS and VCUG findings in 69 (35%) and 58 (30%) cases respectively. Based on our study cohort, the sensitivity of PFUS in detecting UD was significantly higher than that of VCUG: 94% (IQR: 89-97) versus 78% (IQR: 73-85, p<0.01), with a trend toward higher specificity: 100% (IQR: 94-100) versus 84% (IQR: 78-84, p=0.05). Enabling direct UD visualisation, PFUS was associated with a positive predictive value (PPV) of 100% (IQR: 97-100) and a negative predictive value (NPV) of 88% (IQR: 78-95), whereas VCUG had an inferior accuracy with a PPV of 84 (IQR: 80-84) and a NPV of 68 (IQR: 62-79). CONCLUSIONS: In clinical practice, VCUG has a lower sensitivity than PFUS. Based on these results, we recommend the usage of dynamic PFUS as part of a non-invasive work-up.

Proton Therapy for 166 Patients with Iris Melanoma: Side Effects and Oncologic Outcomes.

OBJECTIVE: To investigate the oncologic and functional outcomes of a large cohort of patients with a favorable stage of circumscribed and diffuse iris melanoma who underwent primary proton treatment and the risk factors related to initial tumor characteristics and the treatment field architecture. DESIGN: Retrospective, single-center, case study. PARTICIPANTS: We reviewed 225 patients with iris melanoma who were consecutively treated with proton beam therapy at our institution between 1998 and 2020. METHODS: We performed Kaplan-Meier time-to-event analyses and multivariate Cox proportional hazard analyses to identify the impacts of tumor characteristics and target volumes on oncologic and functional outcomes. MAIN OUTCOME MEASURES: We measured local tumor control, eye preservation rates, metastasis-free survival, cataract and glaucoma-directed surgery, intraocular pressure, and changes in visual acuity. RESULTS: Of the 192 patients with tumors confined to the iris (T1a-c) who underwent proton therapy as primary treatment, a total of 166 patients (mean age, 58.4 years; 88 women) with a minimum follow-up of 6 months were included. Multifocal or diffuse tumor spread was present in 77 (46.4%) patients. The median follow-up time was 54.0 (interquartile range, 27.4-91.8 months) months. Local recurrence occurred in 2 patients (1.2%) with circumscribed iris melanoma. Enucleation was a rare event (n = 5, 3%) and no patient developed metastatic disease. A large-treatment field (full aperture, involving > 10 clock hours) was identified as a risk factor for the development of secondary glaucoma (hazard ratio [HR], 6.3; P < 0.001) and subsequent surgical interventions (HR, 10.85; P < 0.001). The large-treatment field group showed a significant decline in visual acuity (logarithm of the minimum angle of resolution > 0.3; log-rank P < 0.0001), which was associated with secondary glaucoma (HR, 3.40; P = 0.002). CONCLUSIONS: Proton therapy provides an effective, noninvasive treatment option for patients with a favorable stage of iris melanoma. Irradiation of the anterior segment for up to 10 clock hours is associated with a low risk of the development of secondary glaucoma and vision loss.

Efficacy and safety of desmopressin on frequency and urgency in female patients with overactive bladder and nocturia, current clinical features and outcomes: A systematic review.

OBJECTIVE: To evaluate the efficacy and safety of desmopressin on frequency and urgency in female patients with overactive bladder (OAB) and nocturia. METHODS: A selective database search was conducted to validate the effectiveness of desmopressin in patients with OAB and nocturia. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were utilised. The meta-analysis included 378 women (five studies) with OAB. The clinical outcomes and adverse events were analysed. RESULTS: The treatment strategy of all the studies included can be divided into three categories: (1) The effect of desmopressin compared with baseline, (2) desmopressin compared with placebo, and (3) desmopressin and anticholinergic combination versus desmopressin monotherapy. There was a significant (50%) reduction in nocturia and urgency episodes after using desmopressin alone. Combined desmopressin and anticholinergic led to a decrease in the frequency of nocturia voids when only using anticholinergic (65% vs. 33.2%). The time increased in the middle to the first nightly voids in the combination arm (65.11 min; p=0.045). The mean incidence (standard deviation) of leak-free episodes was higher under desmopressin than under placebo in the first 4 h (62% [35%] vs. 48% [40%]) and in the first 8 h (55% [37%] vs. 40% [41%]). The safety profile was comparable between treatments. CONCLUSION: Available data indicate that desmopressin is efficacious in significantly reducing nighttime urine production, episodes of nocturia, and urgency episodes. The affectivity of the combination therapy was very high with least side effects for the treatment of OAB/nocturnal polyuria.

Retzius Sparing Radical Prostatectomy Versus Robot-assisted Radical Prostatectomy: Which Technique Is More Beneficial for Prostate Cancer Patients (MASTER Study)? A Systematic Review and Meta-analysis.

CONTEXT: Retzius sparing robot-assisted radical prostatectomy (RS-RARP) is increasingly being used, but results of pertinent studies on perioperative, functional, and oncological outcomes comparing the Retzius sparing approach with standard robot-assisted radical prostatectomy (RARP) remain inconsistent. OBJECTIVE: To evaluate the effectiveness of RS-RARP compared with standard RARP, in terms of perioperative, functional, and oncological outcomes. EVIDENCE ACQUISITION: We performed a systematic search using multiple databases (PubMed, MEDLINE, EMBASE, and Cochrane Central) until March 2021. Only randomized controlled trials (RCTs) and prospective studies were eligible for study inclusion. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were respected. Studies were critically appraised for the risk of bias. Primary outcomes were continence/potency recovery, as well as positive surgical margin (PSM) rates. Secondary outcomes included total intra- and perioperative complication rates. EVIDENCE SYNTHESIS: Four RCTs and six prospective observational studies were included in this systematic review. The meta-analysis revealed that PSM rates in ≤pT2 tumors were statistically significantly higher, following RS-RARP as compared with RARP (risk ratio [RR]=1.39; 95% confidence interval [CI]=[1.01-1.91]). PSM rates in ≥pT3 tumors tended to be higher following RS-RARP (RR=1.36; 95% CI=[0.74-2.50]), although statistical significance was not reached. Immediate continence recovery was higher and significantly advantageous for RS-RARP (RR=1.81; 95% CI=[1.26-2.60]). Continence recovery also tended to be higher at 3 and 6 mo in the RS-RARP group (RR=1.57; 95% CI=[0.69-3.58] and RR=1.22; 95% CI=[0.89-1.66], respectively). The urinary continence recovery at 12 mo was similar in both groups (RR=1.14; 95% CI=[0.98-1.32]). A meta-analysis of included studies showed no significant difference concerning the return of erectile function and major complication rates between RS-RARP and RARP (RR=1.05; 95% CI=[0.76-1.45] and (RR=0.79; 95% CI=[0.07-8.74], respectively). CONCLUSIONS: Available data suggest a statistically significant advantage in favor of RS-RARP in terms of immediate urinary continence recovery. PSM rates in localized ≤pT2 tumors are statistically significantly higher following RS-RARP. Potency and serious complication rates appear to be similar. PATIENT SUMMARY: Our meta-analysis of the current evidence shows a significant advantage for Retzius sparing robot-assisted radical prostatectomy (RS-RARP) over robot-assisted radical prostatectomy in terms of immediate urinary continence recovery, but positive cancer margins are higher following RS-RARP. There was no significant difference in the preservation of erectile function and overall postoperative complication rates between both the techniques.

Cervical ripening after cesarean section: a prospective dual center study comparing a mechanical osmotic dilator vs. prostaglandin E2.

OBJECTIVES: Worldwide, the overall cesarean section is rising. Trial of labor after cesarean (TOLAC) is an overall safe option with an immediate impact on neonatal and maternal short- and long-term health. Since the use of prostaglandins in cervical ripening is associated with an increased risk of uterine rupture, mechanical methods as balloon catheters or osmotic dilators have been suggested for cervical ripening prior to induction of labour. Here we are analyzing and comparing the VBAC rate, as well as maternal and fetal outcome in cervical ripening prior to TOLAC. METHODS: This prospective dual center study analyses maternal and neonatal outcomes of TOLAC in women with an unfavorable cervix requiring cervical ripening agent. The prospective application of an osmotic dilator (Dilapan-S, n=104) was analysed in comparison to the retrospective application of off-label dinoprostone (n=102). RESULTS: The overall fetal and neonatal outcome revealed no significant differences in both groups. Patients receiving cervical ripening with the osmotic dilator delivered vaginally/by ventouse in 52% of cases, compared to 53% when using dinoprostone (p=0.603). The interval between application to onset of labor was significantly higher in the osmotic dilator group (37.9 vs.20.7 h, p=<0.001). However, time from onset of labor to delivery was similar in both groups (7.93 vs. 7.44 h, p=0.758). There was one case of uterine rupture in the dinoprostone group. CONCLUSIONS: Our data shows that the application of the osmotic dilator leads to similar outcomes in VBAC rate and time from onset of labor to delivery as well as safety in both groups compared to off-label use dinoprostone. Cervical ripening using the mechanical dilator is a viable and effective option, without the risk of uterine hyperstimulation.

Duration of deafness impacts auditory performance after cochlear implantation: A meta-analysis.

OBJECTIVE: Hearing loss is a highly disabling condition. Cochlear implantation is an established remedy if conventional hearing aids have failed to alleviate the level of disability. Unfortunately, cochlear implant (CI) performance varies dramatically. This study aims to examine the effects of duration of deafness (DoD) prior to cochlear implantation and the postoperative duration of implant experience with resulting hearing performance in postlingually deaf patients. METHODS: A systematic literature review and two meta-analyses were conducted using the search terms cochlear implant AND duration deafness. Included studies evaluate the correlation between the DoD and auditory performance after cochlear implantation using monosyllabic and sentence tests. Correlation coefficients were determined using Pearson's correlation and Spearman rho. RESULTS: A total of 36 studies were identified and included data on cochlear implantations following postlingual deafness and postoperative speech testing of hearing outcomes for 1802 patients. The mean age ranged from 44 to 68 years with a DoD of 0.1 to 77 years. Cochlear implant use varied from 3 months to 14 years of age. Speech perception, which was assessed by sentence and monosyllabic word perception, was negatively correlated with DoD. Subgroup analyses revealed worse outcomes for longer DoD and shorter postoperative follow-up. CONCLUSION: DoD is one of the most important factors to predict speech perception after cochlear implantation in postlingually deaf patients. The meta-analyses revealed a negative correlation between length of auditory deprivation and postoperative sentence and monosyllabic speech perception. Longer DoD seems to lead to worse CI performance, whereas more experience with CI mitigates the effect.

A systematic review and meta-analysis of clinical and functional outcomes of artificial urinary sphincter implantation in women with stress urinary incontinence.

OBJECTIVE: To evaluate the complications and results of artificial urinary sphincter (AUS) implantation in women with stress urinary incontinence (SUI). METHODS: A selective database search using keywords (1990-2019) was conducted to validate the effectiveness of the AUS in women. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilised. The meta-analysis included 964 women (15 studies) with persistent SUI. The Newcastle-Ottawa score was used to determine the quality of the evidence in each study. The success rate and complications associated with the AUS were analysed. RESULTS: Meta-analysis of the published studies showed that complete continence was achieved at a mean rate of 79.6% (95% confidence interval [CI] 72.2-86.6%) and a significant improvement was achieved in 15% (95% CI 10-25%). The mean (range) follow-up was 22 (6-204) months. The mean number of patients per study was 68. The mean (range) explantation rate was 13 (0-44)%. Vaginal erosion occurred in a mean (range) of 9 (0-27)% and mechanical complications in 13 (0-47)%. Infections accounted for 7% of the complications. The total mean (range) revision rate of the implanted AUS was 15.42 (0-44)%. The mean (range) size of the cuff used was 6.7 (5-10) cm. CONCLUSION: Our present analysis showed that implantation of an AUS in women with severe UI is an effective treatment option after failure of first-line therapy. However, the currently available study population is too small to draw firm conclusions. ABBREVIATIONS: AMS: American Medical Systems; AUS: artificial urinary sphincter; EAU: European Association of Urology; LE: Level of Evidence; PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses; QoL: quality of life; SHELTER: Services and Health for Elderly in Long TERm care (study); SUI: (stress) urinary incontinence.

Psychosis in German prisoners: Comparison of the clinical appearance of psychotic disorder of an imprisoned population with a not detained community group.

Surveys confirm risk factors for the incarceration of patients with psychosis including homelessness and comorbidity. There is also agreement that severe psychosis can lead to violence. Data describing prisoners with psychosis in Germany are scarce. We aimed to compare patients with psychosis in a prison hospital and patients with psychosis in a community hospital. Demographic data were collected, as well as comorbidity in the form of substance dependence and a psychiatric assessment using the German version of the 18-item Brief Psychiatric Rating Scale (BPRS) and the Positive and Negative Syndrome Scale (PANSS). In the prison hospital group more patients were homeless (17 versus 2%) and non-German (36 versus 4%). There were also more patients with substance dependence or abuse in the prison hospital group. The total scores of BPRS and PANSS were lower in the prison hospital group (BPRS, 43.8 versus 51.2; PANSS, 71.5 versus 83.7). We assume that social disintegration for mentally disturbed offenders prior to incarceration hindered effective treatment. To avoid further social disintegration and possible further deterioration of mental health status of released offenders, which may lead to reoffending after imprisonment, discharge management after release from prison should be improved.

Milan criteria in the MELD era-is it justifiable to extend the limits for orthotopic liver transplantation?

BACKGROUND: The Milan criteria (MC) are widely used for the indication of liver transplantation (LTx) in hepatocellular carcinoma (HCC). Good long-term results have also been reported following LTx for patients exceeding the MC. In this article, we compare the overall and recurrence-free survival of our patients fulfilling and exceeding the MC according to the post-transplant histopathological results. PATIENTS AND METHODS: Data from 120 patients with HCC (22 females and 98 males) were analyzed. The median patient age was 61 years (Q1, Q3 54.7, 65.4), and the median MELD score was 11 (Q1, Q3 8, 15). The median follow-up period was 53 months (Q1, Q3 16.6, 78). Patients were categorized into established criteria (MC, up-to-seven (UTS), Asan criteria, AFP score), and the outcome of the individual groups was compared. RESULTS: Seventy-four of 120 patients fulfilled the MC, 86 patients met the UTS criteria, 85 patients fulfilled the Asan criteria, and 79 patients had an AFP score less than or equal to 2. The 1- and 5-year survival rates of all patients were 76.7% and 55.6%, respectively. In total, 14.2% of all patients (5.4% of patients who met the MC, 7% of patients who met the UTS criteria, 5.9% of patients who met the Asan criteria, and 6.3% of patients who had an AFP score less than 2) experienced recurrence. CONCLUSIONS: The outcomes of the patients were comparable to those reported in the current literature. In our population, similar recurrence and survival rates of the patients were noted for patients fulfilling the UTS criteria irrespective of fulfilling or exceeding the MC. Consequently, we consider using UTS criteria as the extended criterion for LTx indication.

The transversus abdominis plane block may reduce chronic postoperative pain one year after TAPP ingunial hernia repair.

INTRODUCTION: Chronic postoperative inguinal pain (CPIP) is defined as pain impacting daily activities lasting at least 3 months. With an incidence of 0.5-6.0%, chronic pain affects many patients who underwent inguinal hernia repair (IHR). Early severe postoperative pain has been described as a risk factor for CPIP. Thus, we aim to investigate the impact of the transversus abdominis plane (TAP) block on CPIP. METHODS: From 2013 to 2019 we collected data from individuals who were operated on electively in TAPP technique and who received a preoperative TAP block. RESULTS: Data from 289 patients were selected. 259 patients were male. The mean age was 59.93 years and the mean BMI was 25.72 kg/m2. 252 patients suffered from a primary inguinal hernia. No mesh fixation was conducted. 21 patients reported pain at rest, 26 pain under physical exertion and 13 patients required treatment of their pain. In 6.25% of cases patients reported CPIP. We compared our findings with data from the German Herniamed Registry (unilateral, primary IH, men, no mesh fixation; n = 8.799), because we assume that the majority of these patients did not receive a TAP block. The rate of pain under physical exertion (9.2% vs. 10.05%) and pain requiring treatment (2.45% vs. 2.95%) one year after surgery slightly differs without a statistical significance. CONCLUSIONS: We assume that the TAP block may reduce CPIP, postoperative pain during physical exertion and pain requiring treatment following IHR in TAPP technique. Additional randomized clinical trials are mandatory to evaluate the hypothesis.

Patient reported outcome following incisional hernia repair: A survey on 163 patients at two maximum care hospitals.

INTRODUCTION: Incisional hernias of the abdominal wall are frequent complications after laparotomy (9-20%) and often need incisional hernia repair (IHR). In order to ensure wound healing and to therefore prevent postoperative short and long term morbidity carrying an abdominal binder (AB) and physical rest is frequently advised. However, there is a lack of evidence concerning clinical effects regarding these recommendations. Hence, we conducted a survey to analyze the patient reported outcome following IHR. METHODS: From December 2017 to May 2018, we conducted a survey among 270 patients who underwent open and laparoscopic IHR at two maximum care hospitals. They were interviewed about their type of operation, postoperative treatment, recommendations, and outcome. RESULTS: 163 patients replied to the questionnaire. The average age was 63.2 ±â€¯12 years. 74 patients were female and 89 were male. 32.6% of the patients reported an AB-induced immobility and 71.2% reported that the AB reduced pain after IHR. A prolonged period of physical rest and the use of an AB had no statistical significance on postoperative morbidity. CONCLUSIONS: Due to our findings we assume that the AB may induce immobility and reduce postoperative pain. A prolonged period of physical rest and wearing an AB does not seem to have an impact on the postoperative outcome following IHR. Therefore, a shortened duration of physical rest and wearing an AB following IHR should be taken under consideration. To reveal more evidence on this topic further clinical trials are essential.

Suicide in Older Prisoners in Germany.

As in many countries, the numbers of older prisoners are rising in Germany, but scientific information on this group is scarce. For the current study, a survey was used that included all prison suicides in Germany between the years of 2000 and 2013. Suicide rates of the elderly prisoners exceeded the suicide rates of the general population and the same age group. We observed a continuous decrease in the suicide rate of elderly prisoners. When compared to the younger suicide victims in prison, significantly more elderly suicide victims were: female, of German nationality, remand prisoners, or serving a life sentence. In Germany, elderly prisoners are a vulnerable subpopulation of the prison population. Higher suicide rates than in the same age group in the general population indicate unmet needs regarding mental disorders and their specific treatment.

Bilirubin, urobilinogen, pancreas elastase and bile acid in drain fluid. The GBUP-study: Analysis of biomarkers for a colorectal anastomotic leakage.

PURPOSE: A colorectal anastomotic leakage (CAL) is a major complication after colorectal surgery and leads to high rates of morbidity and prolonged hospital stay. The study aims to evaluate the benefit of using bilirubin, urobilinogen, pancreas elastase and bile acid in the drain fluid (DF) as a predictive marker for the CAL. METHODS: From June 2015 to October 2017 100 patients, who underwent left hemicolectomy (LH), sigma resection (SR), high anterior resection (HAR), low anterior resection (LAR) or reversal of Hartmann's Procedure (ROHP) were included in this monocentric non-randomized prospective clinical trial. During the first four postoperative days (POD) the concentration of bilirubin, urobilinogen, pancreas elastase and bile acid in the DF was measured. RESULTS: In total 100 patients were recruited. 17 were excluded due to intraoperative decisions to conduct a protective stoma. 6 patients had a CAL. The patients of the control group (n = 77) and the patients who suffered from a CAL (n = 6) had no increased concentration of urobilinogen and pancreas elastase in the DF. The concentration of bile acid in the DF of the patients who suffered from a CAL differed from those of the control group on the 4th POD (p = 0.055).The concentration of bilirubin in the DF of the patients who suffered from a CAL significantly differed from those of the control group on the 1st POD (p = 0.031) and on the 3rd POD (p = 0.041). CONCLUSION: Bilirubin and bile acid in the DF may function as a predictive marker for a CAL.

Meta-analysis of subjective complaints of vertigo and vestibular tests after cochlear implantation.

OBJECTIVE: Postoperative vertigo is a common complaint after cochlear implantation, but published incidence rates differ vastly. The aim of the present study was to investigate both subjective complaints of vertigo before and after cochlear implantation and related vestibular diagnostic tests on cochlear implant candidates. DATA SOURCES: We performed a systematic literature search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement in PubMed, Cochrane Register, and EMBASE. REVIEW METHODS: We presented 116 eligible studies investigating subjective complaints of vertigo after cochlear implantation and/or related vestibular diagnostic tests. We conducted three meta-analyses of 46 eligible studies with matched pre- and postoperative data to calculate the odds ratio of new vertigo onset, as well as the impairment of vestibular receptors measured by nystagmography and cervical vestibular evoked myogenic potentials (cVEMP). Postoperative vertigo was calculated from 95 studies and further subdivided by mean age with pooled data. RESULTS: We observed a significant increase in postoperative vertigo and significant impairment of nystagmography and cVEMP detection. Vertigo after cochlear implantation was reported in 9.3% of the patients with a continuous increase in patient age at surgery. In a subgroup of studies, new onset of vertigo was found in 17.4% of the patients. In addition, 7.2% of the patients had persisting vertigo complaints, whereas 11.6% described an altered vertigo quality and 7.7% had their preoperative complaints resolved. A comparison of round window approach and cochleostomy revealed significantly increased vertigo after cochleostomy. Both insertion methods showed similar effects in nystagmography and cVEMP testing. CONCLUSION: Cochlear implantation has a significant impact on subjective vertigo and vestibular receptor function. This is affected by the patient's age at the time of surgery. The surgical technique (round window or cochleostomy) may influence the outcome, but this requires further investigation. Younger patients may compensate better following vestibular dysfunction. Perioperative testing is required to correlate vestibular impairment and subjective complaints. Laryngoscope, 2018 Laryngoscope, 128:2110-2123, 2018.

Induction of labor in patients with an unfavorable cervix after a cesarean using an osmotic dilator versus vaginal prostaglandin.

BACKGROUND: Trial of labor after cesarean (TOLAC) is a viable option for safe delivery. In some cases cervical ripening and subsequent labor induction is necessary. However, the commonly used prostaglandins are not licensed in this subgroup of patients and are associated with an increased risk of uterine rupture. METHODS: This cohort study compares maternal and neonatal outcomes of TOLAC in women (n=82) requiring cervical ripening agents (osmotic dilator vs. prostaglandins). The initial Bishop scores (BSs) were 2 (0-5) and 3 (0-5) (osmotic dilator and prostaglandin group, respectively). In this retrospective analysis, Fisher's exact test, the Kruskal-Wallis rank sum test and Pearson's chi-squared test were utilized. RESULTS: Vaginal birth rate (including operative delivery) was 55% (18/33) in the osmotic dilator group vs. 51% (25/49) in the dinoprostone group (P 0.886). Between 97% and 92% (32/33 and 45/49) (100%, 100%) of neonates had an Apgar score of >8 after 1 min (5, 10 min, respectively). The time between administration of the agent and onset of labor was 36 and 17.1 h (mean, Dilapan-S® group, dinoprostone group, respectively). Time from onset of labor to delivery was similar in both groups with 4.4 and 4.9 h (mean, Dilapan-S® group, dinoprostone group, respectively). Patients receiving cervical ripening with Dilapan-S® required oxytocin in 97% (32/33) of cases. Some patients presented with spontaneous onset of labor, mostly in the dinoprostone group (24/49, 49%). Amniotomy was performed in 64% and 49% (21/33 and 24/49) of cases (Dilapan-S® group and dinoprostone group, respectively). CONCLUSIONS: This pilot study examines the application of an osmotic dilator for cervical ripening to promote vaginal delivery in women who previously delivered via cesarean section. In our experience, the osmotic dilator gives obstetricians a chance to perform induction of labor in these women.

Spatial distribution of allergenic pollen through a large metropolitan area.

For nearly a decade, the majority of the world's population has been living in cities, including a considerable percentage of people suffering from pollen allergy. The increasing concentration of people in cities results in larger populations being exposed to allergenic pollen at the same time. There is almost no information about spatial distribution of pollen within cities as well as a lack of information about the possible impact to human health. To obtain this increasing need for pollen exposure studies on an intra-urban scale, a novelty screening network of 14 weekly changed pollen traps was established within a large metropolitan area-Berlin, Germany. Gravimetric pollen traps were placed at a uniform street-level height from March until October 2014. Three important allergenic pollen types for Central Europe-birch (Betula), grasses (Poaceae), and mugwort (Artemisia)-were monitored. Remarkable spatial and temporal variations of pollen sedimentation within the city and the influences by urban local sources are shown. The observed differences between the trap with the overall highest and the trap with the overall lowest amount of pollen sedimentation were in the case of birch pollen 245%, grass pollen 306%, and mugwort pollen 1962%. Differences of this magnitude can probably lead to different health impacts on allergy sufferers in one city. Therefore, pollen should be monitored preferably in two or more appropriate locations within large cities and as a part of natural air quality regulations.

Diagnosis of HCC for patients with cirrhosis using miRNA profiles of the tumor-surrounding tissue - A statistical model based on stepwise penalized logistic regression.

The presence of hepatocellular carcinoma (HCC) is a significant complication of cirrhosis because it changes the prognosis and the treatment of the patients. By now, contrast-enhanced CT and MR scans are the most reliable tools for the diagnosis of HCC; however, in some cases, a biopsy of the tumor is necessary for the final diagnosis. The aim of the study was to develop a diagnostic tool using the microRNA (miRNA) profiles of the tissue surrounding the HCC tumor combined with clinical parameters in statistical models. At a transplantation setting, 32 patients with HCC and cirrhosis (B) were compared to 22 patients suffering from cirrhosis only (A). The diagnosis and exclusion of HCC was confirmed following the histopathological examination of the explanted liver. The HCC patients were significantly older than the patients with cirrhosis only (B: 60.6 and A: 49.9, p<0.001) and showed higher levels of ALT (A: 0.76µkat/l, B: 1.02µkat/, p=0.006) and AFP (A: 5.8ng/ml, B: 70.3ng/ml, p<0.001), whereas the bilirubin levels were higher in the cirrhosis only group (p=0.002). Using age (cut-off 50.23years) and AFP (cut-off 4.2ng/ml) thresholds, the levels of expression of miR-1285-3p and miR-943 differentiated between the patients with HCC and cirrhosis from those with cirrhosis only with an accuracy of 96.3%. This is the first report about the use of stepwise penalized logistic regression and decision tree analyses of miRNA expressions in the tumor-surrounding tissue combined with clinical parameters for the diagnosis of HCC.

Antenatal body mass index (BMI) and weight gain in pregnancy - its association with pregnancy and birthing complications.

BACKGROUND: Overweight and obesity is a serious health risk in both developed and developing nations. It is a common finding among women in their reproductive age. Half of patients entering their pregnancy in the US have a BMI >25.0 and therefore qualify as overweight or obese. Moreover, there is a tendency towards increased weight gain during pregnancy. Studies have shown that gestational overweight is associated with complications in pregnancy and birthing as well as short-term and long-term impacts on neonatal outcome in childhood and adulthood. METHODS: Five hundred and ninety-one women visiting our tertiary perinatal center in 2014 were analyzed for antenatal BMI, gestational weight gain, as well as pregnancy outcome and complication together with neonatal weight and outcome. Pregnancy weight gain was assessed based on the IOM guidelines (Institute of Medicine) issued in 2009. RESULTS: Twenty-nine percent of our population was overweight with a BMI of more than 25.0. The general weight gain was in every BMI group similar (median ranging from 12.0 to 14.0 kg). Approximately one third gained more than the appropriate amount (37%, P<0.001). Women with more gestational weight were at risk of labor induction (55.0% vs. 45.7% labor induction in total, P=0.007). Strikingly, those patients were found to have significantly higher rates of secondary cesarean section (22.4% vs. 15.4%) and decreased chances of spontaneous vaginal birth (57.5% vs. 61.4%) (P=0.008). Furthermore women with a pregnancy weight gain in excess of the guidelines gave birth to neonates with a higher birth weight (>75.centile, 28.3% vs. 21.3%, P<0.001). CONCLUSIONS: Altogether, one third of the analyzed population is already overweight or obese when entering pregnancy. A higher gestational weight gain than the recommended amount was found in 37% of cases. We found an association with pregnancy and birthing complications as well as higher infant weight. This highlights the importance of preconceptive and prenatal advice, and if necessary, intervention on BMI and weight gain.
