Cognition and behaviour in frontotemporal dementia with and without amyotrophic lateral sclerosis.

OBJECTIVE: The precise relationship between frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) is incompletely understood. The association has been described as a continuum, yet data suggest that this may be an oversimplification. Direct comparisons between patients who have behavioural variant FTD (bvFTD) with and without ALS are rare. This prospective comparative study aimed to determine whether there are phenotypic differences in cognition and behaviour between patients with FTD-ALS and bvFTD alone. METHODS: Patients with bvFTD or FTD-ALS and healthy controls underwent neuropsychological testing, focusing on language, executive functions and social cognition. Behavioural change was measured through caregiver interview. Blood samples were screened for known FTD genes. RESULTS: 23 bvFTD, 20 FTD-ALS and 30 controls participated. On cognitive tests, highly significant differences were elicited between patients and controls, confirming the tests' sensitivities to FTD. bvFTD and FTD-ALS groups performed similarly, although with slightly greater difficulty in patients with ALS-FTD on category fluency and a sentence-ordering task that assesses grammar production. Patients with bvFTD demonstrated more widespread behavioural change, with more frequent disinhibition, impulsivity, loss of empathy and repetitive behaviours. Behaviour in FTD-ALS was dominated by apathy. The C9ORF72 repeat expansion was associated with poorer performance on language-related tasks. CONCLUSIONS: Differences were elicited in cognition and behaviour between bvFTD and FTD-ALS, and patients carrying the C9ORF72 repeat expansion. The findings, which raise the possibility of phenotypic variation between bvFTD and FTD-ALS, have clinical implications for early detection of FTD-ALS and theoretical implications for the nature of the relationship between FTD and ALS.

Outpatient visits versus telephone interviews for postoperative care: a randomized controlled trial.

INTRODUCTION AND HYPOTHESIS: Our aim was to determine whether postoperative telephone follow-up was noninferior to in-person clinic visits based on patient satisfaction. Secondary outcomes were safety and clinical outcomes. METHODS: Women scheduled for pelvic surgery were recruited from a single academic institution and randomized to clinic or telephone follow-up. The clinic group returned for visits 2, 6, and 12 weeks postoperatively and the telephone group received a call from a nurse at the same time intervals. Women completed the Consumer Assessment of Healthcare Providers and Systems Surgical Care Survey (S-CAHPS) questionnaire, Pelvic Floor Distress Inventory (PFDI)-20, and pain scales prior to and 3 months postoperatively. Randomized patients who completed the S-CAHPS at 3 months were included for analysis. Sample size calculations, based on a 15% noninferiority limit in the S-CAHPS global assessment surgeon rating, required 100 participants, with power = 80% and alpha = 0.025. RESULTS: From October 2016 to November 2017, 100 participants were consented, underwent surgery, were randomized, and included in the final analysis (clinic group n = 50, telephone group n = 50). Mean age was 58.5 ± 12.2 years. Demographic data and surgery type, dichotomized into outpatient and inpatient, did not differ between groups. The S-CAHPS global assessment surgeon rating from patients in the telephone group was noninferior to the clinic group (92 vs 88%, respectively, rated their surgeons 9 and10, with a noninferiority limit of 36.1; p = 0.006). Adverse events did not differ between groups (n = 26; 57% fclinic vs 43% telephone; p = 0.36). Patients in the telephone group did not require additional emergency room or primary care visits. Clinical outcome measures improved in both groups, with no differences (all p > 0.05). CONCLUSIONS: Telephone follow-up after pelvic floor surgery results in noninferior patient satisfaction, without differences in clinical outcomes or adverse events. Telephone follow-up may improve healthcare quality and decrease patient and provider burden for postoperative care.

Trends in patient procurement of postoperative opioids and route of hysterectomy in the United States from 2004 through 2014.

BACKGROUND: The opioid epidemic in the United States is a public health emergency. Minimally invasive surgical technology has decreased length of hospital stay, improved postoperative recovery, and decreased postoperative pain. Hysterectomy is one of the most commonly performed surgeries in the United States. Increasing trends in minimally invasive gynecologic surgery are expected to reduce patients' postoperative pain. It is unclear whether this assumption has resulted in decreasing postoperative opioid prescriptions or patient need for these prescriptions, as prescribing patterns may be contributing to the current opioid public health emergency. OBJECTIVE: We sought to describe opioid prescribing and patient procurement practices for postoperative pain at time of discharge for benign hysterectomy from 2004 through 2014 using the Truven Health Analytics MarketScan Research Database. The trends of the route of hysterectomy over this time period were concomitantly described to reflect the movement toward more minimally invasive approaches. STUDY DESIGN: The Truven Health Analytics MarketScan Research Database including the Commercial Claims and Encounters Database, and the Medicare Supplemental and Coordination of Benefits Database were utilized. Current Procedural Terminology, 4th Edition, and International Classification of Diseases, Ninth Revision, codes identified all patients who underwent a hysterectomy for benign indications from 2004 through 2014. Hysterectomy routes were categorized into abdominal, laparoscopic, and vaginal. The MarketScan database captures prescriptions filled at a retail or mail-order pharmacy and does not capture prescriptions filled within the inpatient, hospital facility. The days of opioids procured by patients at the time of discharge were identified for each encounter. Descriptive statistics were used to summarize data within the entire study period. Although this article is purely descriptive, further analyses were conducted for exploratory purposes only. analysis of variance and χ2 analyses were used for continuous and categorical variables, respectively. Multiple linear regression models were used to describe associations between variables of interest and postoperative opioid prescriptions. RESULTS: We identified 793,016 patients who underwent a hysterectomy for benign indications from 2004 through 2014. Of these, 96% were identified from the Commercial Claims and Encounters Database. During the study period, the overall route of hysterectomy was categorized into 40.5% abdominal, 42.0% laparoscopic, and 17.5% vaginal hysterectomy. The route of hysterectomy changed from 60.2-25.6% (a decrease of Δ = 34.58; 95% confidence interval, 33.96-35.20) for abdominal, 17.0-61.9% (an increase of Δ = 44.83; 95% confidence interval, 44.21-45.44) for laparoscopic, and 22.8-12.6% (a decrease of Δ = 10.25; 95% confidence interval, 9.77-10.73) for vaginal. At discharge, the percentage of patients who were prescribed opioids and filled them increased from 25.6-82.1% (an increase of Δ = 56.50; 95% confidence interval, 55.88-57.13 with P < .001) from 2004 through 2014 for all hysterectomy routes. Additionally, the quantity of opioids prescribed also increased. CONCLUSION: Opioid prescriptions filled for postoperative pain after hysterectomy substantially increased from 2004 through 2014. Opioid prescription procurement has increased despite a concomitant increase in minimally invasive hysterectomy routes. In light of the current opioid epidemic, physicians must recognize that postoperative prescribing practices may contribute to chronic opioid use. Heightened awareness of opioid prescribing practices following surgery is critically important to decrease risk of development of chronic opioid dependence.

Functional neuroanatomical associations of working memory in early-onset Alzheimer's disease.

OBJECTIVE: To characterize metabolic correlates of working memory impairment in clinically defined subtypes of early-onset Alzheimer's disease. BACKGROUND: Established models of working memory suggest a key role for frontal lobe function, yet the association in Alzheimer's disease between working memory impairment and visuospatial and language symptoms suggests that temporoparietal neocortical dysfunction may be responsible. METHODS: Twenty-four patients with predominantly early-onset Alzheimer's disease were clinically classified into groups with predominantly amnestic, multidomain or visual deficits. Patients underwent neuropsychological evaluation focused on the domains of episodic and working memory, T1-weighted magnetic resonance imaging and brain fluorodeoxyglucose positron emission tomography. Fluorodeoxyglucose positron emission tomography data were analysed by using a region-of-interest approach. RESULTS: Patients with multidomain and visual presentations performed more poorly on tests of working memory compared with amnestic Alzheimer's disease. Working memory performance correlated with glucose metabolism in left-sided temporoparietal, but not frontal neocortex. Carriers of the apolipoprotein E4 gene showed poorer episodic memory and better working memory performance compared with noncarriers. CONCLUSIONS: Our findings support the hypothesis that working memory changes in early-onset Alzheimer's disease are related to temporoparietal rather than frontal hypometabolism and show dissociation from episodic memory performance. They further support the concept of subtypes of Alzheimer's disease with distinct cognitive profiles due to prominent neocortical dysfunction early in the disease course.

Examining the language and behavioural profile in FTD and ALS-FTD.

BACKGROUND: A proportion of patients with behavioural variant frontotemporal dementia (bvFTD) develop amyotrophic lateral sclerosis (ALS). It is currently unknown whether the behavioural and cognitive syndrome in bvFTD with ALS (ALS-FTD) is indistinguishable from that of bvFTD alone. METHODS: A retrospective cohort of 241 patients with clinical diagnoses of bvFTD (n=185) or ALS-FTD (n=56) was examined with respect to behavioural, cognitive and neuropsychiatric symptoms. Features were rated as present or absent based on information recorded from clinical interviews and detailed neuropsychological assessment. RESULTS: A number of behavioural and affective changes were reported more frequently in bvFTD than ALS-FTD: social disinhibition (p<0.001), inertia (p<0.001), loss of sympathy and empathy (p=0.008), repetitive behaviours (p<0.001) and dietary changes (p<0.001). Warmth of affect demonstrated in the clinic setting was reported more often in ALS-FTD than bvFTD (p<0.001). Executive impairments occurred equally in both groups. Language impairments were more common in ALS-FTD than bvFTD: agrammatism (p<0.017) and impaired sentence comprehension (p<0.036). Psychotic features were relatively rare and did not distinguish the groups. CONCLUSIONS: Our findings suggest differences between bvFTD and ALS-FTD. In particular, while changes in social behaviour are prominent in bvFTD alone, there may be a comparatively greater degree of language impairment in ALS-FTD. Prospective exploration of the pattern of differences between these groups will be essential. Identification of a distinct neuropsychological phenotype in ALS-FTD may have clinical implications for early diagnosis, disease management and care planning and theoretical implications for our understanding of the relationship between ALS and FTD.

Suprapubic versus transurethral bladder drainage following reconstructive pelvic surgery: a comparison of patient satisfaction and quality of life.

INTRODUCTION AND HYPOTHESIS: To assess the differences in patient-reported, catheter-specific satisfaction and quality of life with either suprapubic or transurethral postoperative bladder drainage following reconstructive pelvic surgery. METHODS: This was a prospective study of all eligible women who were scheduled to undergo reconstructive surgery requiring bladder drainage during the study period November 2013 to March 2015. Women who did not undergo the planned procedure(s) or did not require bladder drainage were excluded. The primary outcome was patient-reported quality of life using catheter-specific instruments including the Catheter-related Quality of Life (CIQOL) instrument, and a modified version of the Intermittent Self-Catheterization Questionnaire (ISC-Q), designed to evaluate aspects of catheter-related quality of life and satisfaction specific to the needs of the individual. RESULTS: A total of 178 women were analyzed, 108 in the transurethral catheter group and 70 in the suprapubic group. Women with suprapubic bladder drainage had higher quality of life and satisfaction scores than women with transurethral bladder drainage as measured by the ISC-Q (68.31 ± 16.87 vs. 54.04 ± 16.95, mean difference 14.27, 95 % CI 9.15 - 19.39). There was no difference in quality of life by the CIQOL. After regression analysis, women with suprapubic bladder drainage were more satisfied with their catheter-specific needs despite longer duration of catheter use, more concurrent continence surgery, and higher trait anxiety. CONCLUSIONS: Differences in catheter-specific quality of life and patient satisfaction scores favoring suprapubic bladder drainage support its continued use in appropriately selected women for treatment of temporary postoperative urinary retention after reconstructive pelvic surgery.

Sunshine Act: shedding light on inaccurate disclosures at a gynecologic annual meeting.

BACKGROUND: Physicians and hospital systems often have relationships with biomedical manufacturers to develop new ideas, products, and further education. Because this relationship can influence medical research and practice, reporting disclosures are necessary to reveal any potential bias and inform consumers. The Sunshine Act was created to develop a new reporting system of these financial relationships called the Open Payments database. Currently all disclosures submitted with research to scientific meetings are at the discretion of the physician. We hypothesized that financial relationships between authors and the medical industry are underreported. OBJECTIVES: We aimed to describe concordance between physicians' financial disclosures listed in the abstract book from the 41st annual scientific meeting of the Society of Gynecologic Surgeons to physician payments reported to the Center for Medicaid and Medicare Services Open Payments database for the same year. STUDY DESIGN: Authors and scientific committee members responsible for the content of the 41st annual scientific meeting of the Society of Gynecologic Surgeons were identified from the published abstract book; each abstract listed disclosures for each author. Abstract disclosures were compared with the transactions recorded on the Center for Medicaid and Medicare Services Open Payments database for concordance. Two authors reviewed each nondisclosed Center for Medicaid and Medicare Services listing to determine the relatedness between the company listed on the Center for Medicaid and Medicare Services and abstract content. RESULTS: Abstracts and disclosures of 335 physicians meeting inclusion criteria were reviewed. A total of 209 of 335 physicians (62%) had transactions reported in the Center for Medicaid and Medicare Services, which totaled $1.99 million. Twenty-four of 335 physicians (7%) listed companies with their abstracts; 5 of those 24 physicians were concordant with the Center for Medicaid and Medicare Services. The total amount of all nondisclosed transactions was $1.3 million. Transactions reported in the Center for Medicaid and Medicare Services associated with a single physician ranged from $11.72 to $405,903.36. Of the 209 physicians with Center for Medicaid and Medicare Services transactions that were not disclosed, the majority (68%) had at least 1 company listed in the Center for Medicaid and Medicare Services that was determined after review to be related to the subject of their abstract. CONCLUSION: Voluntary disclosure of financial relationships was poor, and the majority of unlisted disclosures in the abstract book were companies related to the scientific content of the abstract. Better transparency is needed by physicians responsible for the content presented at gynecological scientific meetings.

Histone deacetylases (HDACs) in frontotemporal lobar degeneration.

AIMS: Frontotemporal lobar degeneration (FTLD) is clinically and pathologically heterogeneous. Although associated with variations in MAPT, GRN and C9ORF72, the pathogenesis of these, and of other nongenetic, forms of FTLD, remains unknown. Epigenetic factors such as histone regulation by histone deacetylases (HDAC) may play a role in the dysregulation of transcriptional activity, thought to underpin the neurodegenerative process. METHODS: The distribution and intensity of HDACs 4, 5 and 6 was assessed semi-quantitatively in immunostained sections of temporal cortex with hippocampus, and cerebellum, from 33 pathologically confirmed cases of FTLD and 27 controls. RESULTS: We found a significantly greater intensity of cytoplasmic immunostaining for HDAC4 and HDAC6 in granule cells of the dentate gyrus in cases of FTLD overall compared with controls, and specifically in cases of FTLD tau-Picks compared with FTLD tau-MAPT and controls. No differences were noted between FTLD-TDP subtypes, or between the different genetic and nongenetic forms of FTLD. No changes were seen in HDAC5 in any FTLD or control cases. CONCLUSIONS: Dysregulation of HDAC4 and/or HDAC6 could play a role in the pathogenesis of FTLD-tau associated with Pick bodies, although their lack of immunostaining implies that such changes do not contribute directly to the formation of Pick bodies.

Do NIA-AA criteria distinguish Alzheimer's disease from frontotemporal dementia?

BACKGROUND: Clinical criteria are important for improving diagnostic accuracy and ensuring comparability of patient cohorts in research studies. OBJECTIVE: The aim was to assess the National Institute on Aging and Alzheimer's Association (NIA-AA) criteria for Alzheimer's disease (AD) dementia in AD and frontotemporal lobar degeneration (FTLD). METHODS: Two hundred twelve consecutive patients with pathologically confirmed AD or FTLD who were clinically assessed in a specialist cognitive unit were identified. Fifty-five patients were excluded predominantly because of insufficient clinical information. Anonymized clinical data were rated against the NIA-AA criteria by raters who were blinded to clinical and pathologic diagnosis. RESULTS: The NIA-AA AD dementia criteria had a sensitivity of 65.6% for probable and 79.5% for possible AD and a specificity of 95.2% and 94.0% for probable and possible, respectively. CONCLUSION: In patients with FTLD and predominantly early-onset AD, the NIA-AA AD dementia criteria have high specificity but lower sensitivity. The high specificity is due to the broad exclusion criteria.

No interaction between tau and TDP-43 pathologies in either frontotemporal lobar degeneration or motor neurone disease.

INTRODUCTION: Frontotemporal lobar degeneration (FTLD) is classified mainly into FTLD-tau and FTLD-TDP according to the protein present within inclusion bodies. While such a classification implies only a single type of protein should be present, recent studies have demonstrated dual tau and TDP-43 proteinopathy can occur, particularly in inherited FTLD. METHODS: We therefore investigated 33 patients with FTLD-tau (including 9 with MAPT mutation) for TDP-43 pathological changes, and 45 patients with FTLD-TDP (including 12 with hexanucleotide expansion in C9ORF72 and 12 with GRN mutation), and 23 patients with motor neurone disease (3 with hexanucleotide expansion in C9ORF72), for tauopathy. RESULTS: TDP-43 pathological changes, of the kind seen in many elderly individuals with Alzheimer's disease, were seen in only two FTLD-tau cases--a 70-year-old male with exon 10 + 13 mutation in MAPT, and a 73-year-old female with corticobasal degeneration. Such changes were considered to be secondary and probably reflective of advanced age. Conversely, there was generally only scant tau pathology, usually only within hippocampus and/or entorhinal cortex, in most patients with FTLD-TDP or MND. The extent of tau pathology in FTLD-TDP and MND, as with amyloid ß protein, may relate to increased age and possession of Apolipoprotein ε4 allele. CONCLUSION: We find no predilection or predisposition towards an accompanying TDP-43 pathology in patients with FTLD-tau, irrespective of presence or absence of MAPT mutation, or that genetic changes associated with FTLD-TDP predispose towards excessive tauopathy. Where the two processes coexist, this is limited and probably causatively independent of each other.

Patterns of microglial cell activation in frontotemporal lobar degeneration.

AIMS: Pathological heterogeneity within patients with frontotemporal lobar degeneration (FTLD) in general precludes the accurate assignment of diagnostic subtype in life. The aim of this study was to assess the extent of microglial cell activation in FTLD in order to determine whether it might be possible to employ this as a diagnostic marker in vivo using PET ligand [11C](R)-PK11195 in order to differentiate cases of FTLD according to histological subtype. METHODS: The distribution and extent of microglial cell activation was assessed semi-quantitatively in cortical grey and subcortical white matter of CD68 immunostained sections of frontal and temporal cortex from 78 pathologically confirmed cases of FTLD, 13 of Alzheimer's disease (AD) and 13 controls. RESULTS: Significantly higher levels of microglial cell activation than controls occurred in all four regions in FTLD, and in three of the four regions in AD. Microglial activation was greater in frontal subcortical white matter in FTLD than AD, whereas it was higher in temporal cortical grey matter in AD than FTLD. Microglial cell activation was significantly higher in temporal subcortical white matter in FTLD-MAPT than in other genetic (GRN, C9ORF72) or non-genetic forms of FTLD. CONCLUSIONS: The present study suggests that high levels of microglial cell involvement in temporal lobe (subcortical white matter) might serve as a marker of inherited FTLD associated with intronic mutations in MAPT, with a relatively intense signal in this region in PET studies using [11C](R)-PK11195 as microglial cell marker could indicate the presence of MAPT mutation in vivo.

Repair of Vesicovaginal Fistulae: A Systematic Review.

OBJECTIVE: To assess and compile the current level of evidence regarding successful surgical treatment of vesicovaginal fistulae and how these perioperative interventions affect anatomic, patient-centered, and adverse outcomes. DATA SOURCES: PubMed and EMBASE were searched from inception through September 9, 2022. METHODS OF STUDY SELECTION: This review included comparative studies (of any sample size) and single-group studies (1,000 or more participants) of primary or recurrent vesicovaginal fistula (ie, vesicovaginal fistula, urethrovaginal fistula, and bladder neck-vaginal fistula). We evaluated preintervention assessment or management, various techniques for intraoperative management, and postoperative management. Outcomes of interest included anatomic and objective outcomes (such as successful repair, fistula closure, urinary incontinence, recurrent fistula, perioperative complications) and subjective outcomes (such as voiding symptoms and quality of life). Abstracts and full-text articles were screened in duplicate, and study descriptions and findings were extracted into standardized extraction forms. Risk of bias was assessed independently by two investigators and adjudicated by a third. Study quality was summarized with standardized tools. We conducted random-effects model and restricted maximum-likelihood meta-analyses of relative risks when at least three studies compared similar interventions and reported similar outcome measures. TABULATION, INTEGRATION, AND RESULTS: Forty-six studies met the inclusion criteria. Studies were categorized into 11 domains: 1) preoperative assessment, 2) preoperative and postoperative physical therapy, 3) route of surgery, 4) incorporation of a flap, 5) trimming, 6) layered closure, 7) intraoperative antibiotics, 8) fibrin glue, 9) fascial sling, 10) postoperative Foley catheter duration, and 11) quality of life. Although the strength of the data is insufficient, preoperative phenazopyridine, physical therapy, layered closure, and intraoperative antibiotics seemed to improve the rate of successful fistula repair. Route of surgery (vaginal vs abdominal laparotomy) was determined primarily by surgeon preference and showed no difference in successful fistula repair. In addition, use of interpositional flaps, trimming fistula edges, fibrin glue, and fascial sling did not show significant improvement in rates of fistula cure. Overall, quality-of-life scores improved postoperatively regardless of route of repair and use of interpositional flaps. CONCLUSION: Our findings highlight the limited information available to guide evidence-based treatment of vesicovaginal fistula repair. Overall, high-quality evidence is lacking to provide guidelines; therefore, expert opinion remains the primary influence for fistula repair recommendations.

Sexual Harassment, Abuse, and Discrimination in Obstetrics and Gynecology: A Systematic Review.

Importance: Unlike other surgical specialties, obstetrics and gynecology (OB-GYN) has been predominantly female for the last decade. The association of this with gender bias and sexual harassment is not known. Objective: To systematically review the prevalence of sexual harassment, bullying, abuse, and discrimination among OB-GYN clinicians and trainees and interventions aimed at reducing harassment in OB-GYN and other surgical specialties. Evidence Review: A systematic search of PubMed, Embase, and ClinicalTrials.gov was conducted to identify studies published from inception through June 13, 2023.: For the prevalence of harassment, OB-GYN clinicians and trainees on OB-GYN rotations in all subspecialties in the US or Canada were included. Personal experiences of harassment (sexual harassment, bullying, abuse, and discrimination) by other health care personnel, event reporting, burnout and exit from medicine, fear of retaliation, and related outcomes were included. Interventions across all surgical specialties in any country to decrease incidence of harassment were also evaluated. Abstracts and potentially relevant full-text articles were double screened.: Eligible studies were extracted into standard forms. Risk of bias and certainty of evidence of included research were assessed. A meta-analysis was not performed owing to heterogeneity of outcomes. Findings: A total of 10 eligible studies among 5852 participants addressed prevalence and 12 eligible studies among 2906 participants addressed interventions. The prevalence of sexual harassment (range, 250 of 907 physicians [27.6%] to 181 of 255 female gynecologic oncologists [70.9%]), workplace discrimination (range, 142 of 249 gynecologic oncologists [57.0%] to 354 of 527 gynecologic oncologists [67.2%] among women; 138 of 358 gynecologic oncologists among males [38.5%]), and bullying (131 of 248 female gynecologic oncologists [52.8%]) was frequent among OB-GYN respondents. OB-GYN trainees commonly experienced sexual harassment (253 of 366 respondents [69.1%]), which included gender harassment, unwanted sexual attention, and sexual coercion. The proportion of OB-GYN clinicians who reported their sexual harassment to anyone ranged from 21 of 250 AAGL (formerly, the American Association of Gynecologic Laparoscopists) members (8.4%) to 32 of 256 gynecologic oncologists (12.5%) compared with 32.6% of OB-GYN trainees. Mistreatment during their OB-GYN rotation was indicated by 168 of 668 medical students surveyed (25.1%). Perpetrators of harassment included physicians (30.1%), other trainees (13.1%), and operating room staff (7.7%). Various interventions were used and studied, which were associated with improved recognition of bias and reporting (eg, implementation of a video- and discussion-based mistreatment program during a surgery clerkship was associated with a decrease in medical student mistreatment reports from 14 reports in previous year to 9 reports in the first year and 4 in the second year after implementation). However, no significant decrease in the frequency of sexual harassment was found with any intervention. Conclusions and Relevance: This study found high rates of harassment behaviors within OB-GYN. Interventions to limit these behaviors were not adequately studied, were limited mostly to medical students, and typically did not specifically address sexual or other forms of harassment.

Sporadic Creutzfeldt-Jakob disease presenting as progressive nonfluent aphasia with speech apraxia.

Progressive non-fluent aphasia (PNFA) is typically associated with pathological changes consistent with frontotemporal lobar degeneration. A 65-year-old male presented with effortful speech, markedly impaired naming and features of speech apraxia, consistent with PNFA. Perceptuospatial function, calculation and executive function were intact. Brain SPECT showed left perisylvian hypoperfusion. He deteriorated profoundly over the subsequent eight months, with appearances on diffusion-weighted magnetic resonance imaging typical of sporadic Creutzfeldt-Jakob disease, which was confirmed pathologically at postmortem examination. While the presence of PNFA with speech apraxia is thought to predict underlying tauopathy, sporadic Creutzfeldt-Jakob disease may mimic this presentation and present in a highly circumscribed form not previously described.

Distinct clinical and pathological characteristics of frontotemporal dementia associated with C9ORF72 mutations.

The identification of a hexanucleotide repeat expansion in the C9ORF72 gene as the cause of chromosome 9-linked frontotemporal dementia and motor neuron disease offers the opportunity for greater understanding of the relationship between these disorders and other clinical forms of frontotemporal lobar degeneration. In this study, we screened a cohort of 398 patients with frontotemporal dementia, progressive non-fluent aphasia, semantic dementia or mixture of these syndromes for mutations in the C9ORF72 gene. Motor neuron disease was present in 55 patients (14%). We identified 32 patients with C9ORF72 mutations, representing 8% of the cohort. The patients' clinical phenotype at presentation varied: nine patients had frontotemporal dementia with motor neuron disease, 19 had frontotemporal dementia alone, one had mixed semantic dementia with frontal features and three had progressive non-fluent aphasia. There was, as expected, a significant association between C9ORF72 mutations and presence of motor neuron disease. Nevertheless, 46 patients, including 22 familial, had motor neuron disease but no mutation in C9ORF72. Thirty-eight per cent of the patients with C9ORF72 mutations presented with psychosis, with a further 28% exhibiting paranoid, deluded or irrational thinking, whereas <4% of non-mutation bearers presented similarly. The presence of psychosis dramatically increased the odds that patients carried the mutation. Mutation bearers showed a low incidence of motor stereotypies, and relatively high incidence of complex repetitive behaviours, largely linked to patients' delusions. They also showed a lower incidence of acquired sweet food preference than patients without C9ORF72 mutations. Post-mortem pathology in five patients revealed transactive response DNA-binding protein 43 pathology, type A in one patient and type B in three. However, one patient had corticobasal degeneration pathology. The findings indicate that C9ORF72 mutations cause some but not all cases of frontotemporal dementia with motor neuron disease. Other mutations remain to be discovered. C9ORF72 mutations are associated with variable clinical presentations and pathology. Nevertheless, the findings highlight a powerful association between C9ORF72 mutations and psychosis and suggest that the behavioural characteristics of patients with C9ORF72 mutations are qualitatively distinct. Mutations in the C9ORF72 gene may be a major cause not only of frontotemporal dementia with motor neuron disease but also of late onset psychosis.

Concomitant progressive supranuclear palsy and Lewy body pathology presenting with circumscribed visual memory loss: A clinicopathological case.

A 70-year-old man presented to the clinic with impairment of visual memory and marked predominantly right sided mesial temporal lobe atrophy on imaging. He died 6 years following symptom onset and neuropathological examination showed concomitant progressive supranuclear palsy and Lewy body pathology. Although he did not fulfil clinical criteria for either condition at presentation, we propose that interactions between the two pathologies in mesial temporal regions could result in this atypical clinical phenotype.

Structural and metabolic correlates of neuropsychological profiles in multiple system atrophy and Parkinson's disease.

BACKGROUND: Despite increased recognition of cognitive impairment in Multiple System Atrophy (MSA), its neuroanatomical correlates are not well defined. We aimed to explore cognitive profiles in MSA with predominant parkinsonism (MSA-P) and Parkinson's disease (PD) and their relationship to frontostriatal structural and metabolic changes. METHODS: Detailed clinical and neuropsychological evaluation was performed together with diffusion tensor imaging (DTI) and [18F]-fluoro-deoxyglucose positron emission tomography ([18F]-FDG-PET) in patients with MSA-P (n = 11) and PD (n = 11). We compared clinical and neuropsychological data to healthy controls (n = 9) and correlated neuropsychological data with imaging findings in MSA-P and PD. RESULTS: Patients with MSA-P showed deficits in executive function (Trail Making Test B-A) and scored higher in measures of depression and anxiety compared to those with PD and healthy controls. Widespread frontostriatal white matter tract reduction in fractional anisotropy was seen in MSA-P and PD compared to an imaging control group. Stroop Test interference performance correlated with [18F]-FDG uptake in the bilateral dorsolateral prefrontal cortex (DLPFC) and with white matter integrity between the striatum and left inferior frontal gyrus (IFG) in PD. Trail Making Test performance correlated with corticostriatal white matter integrity along tracts from the bilateral IFG in MSA-P and from the right DLPFC in both groups. CONCLUSION: Executive dysfunction was more prominent in patients with MSA-P compared to PD. DLPFC metabolism and frontostriatal white matter integrity seem to be a driver of executive function in PD, whereas alterations in corticostriatal white matter integrity may contribute more to executive dysfunction in MSA-P.

Prescription Opioid Use for Acute Pain and Persistent Opioid Use After Gynecologic Surgery: A Systematic Review.

OBJECTIVE: To assess the amount of opioid medication used by patients and the prevalence of persistent opioid use after discharge for gynecologic surgery for benign indications. DATA SOURCES: We systematically searched MEDLINE, EMBASE, and ClinicalTrials.gov from inception to October 2020. METHODS OF STUDY SELECTION: Studies with data on gynecologic surgical procedures for benign indications and the amount of outpatient opioids consumed, or the incidence of either persistent opioid use or opioid-use disorder postsurgery were included. Two reviewers independently screened citations and extracted data from eligible studies. TABULATION, INTEGRATION, AND RESULTS: Thirty-six studies (37 articles) met inclusion criteria. Data were extracted from 35 studies; 23 studies included data on opioids consumed after hospital discharge, and 12 studies included data on persistent opioid use after gynecologic surgery. Average morphine milligram equivalents (MME) used in the 14 days after discharge were 54.0 (95% CI 39.9-68.0, seven tablets of 5-mg oxycodone) across all gynecologic surgery types, 35.0 (95% CI 0-75.12, 4.5 tablets of 5-mg oxycodone) after a vaginal hysterectomy, 59.5 (95% CI 44.4-74.6, eight tablets of 5-mg oxycodone) after laparoscopic hysterectomy, and 108.1 (95% CI 80.5-135.8, 14.5 tablets of 5-mg oxycodone) after abdominal hysterectomy. Patients used 22.4 MME (95% CI 12.4-32.3, three tablets of 5-mg oxycodone) within 24 hours of discharge after laparoscopic procedures without hysterectomy and 79.8 MME (95% CI 37.1-122.6, 10.5 tablets of 5-mg oxycodone) from discharge to 7 or 14 days postdischarge after surgery for prolapse. Persistent opioid use occurred in about 4.4% of patients after gynecologic surgery, but this outcome had high heterogeneity due to variation in populations and definitions of the outcome. CONCLUSION: On average, patients use the equivalent of 15 or fewer 5-mg oxycodone tablets (or equivalent) in the 2 weeks after discharge after major gynecologic surgery for benign indications. Persistent opioid use occurred in 4.4% of patients who underwent gynecologic surgery for benign indications. Our findings could help surgeons minimize overprescribing and reduce medication diversion or misuse. SYSTEMATIC REVIEW REGISTRATION: PROSPERO, CRD42020146120.
