Movement disorders associated with donepezil have been only rarely reported. Herein, we describe an older woman who developed myoclonus secondary to donepezil. A 61-year-old female presented with brief involuntary twitching. The patient reported that she consulted a general practitioner about 1 month before due to memory complaints. A diagnosis of mild cognitive impairment was made. Donepezil was started. After 4 weeks, she presented to our emergency department due to significant twitching. Multifocal myoclonus was observed. These movements occurred during rest and voluntary movement. Laboratory exams and cerebrospinal fluid analysis were normal. A cranial computed tomography and brain magnetic resonance imaging were unremarkable. Electroencephalography did not show epileptic activity. Electromyography revealed burst durations varying between 50 and 100 ms. Diazepam intravenous was started, which improved her abnormal movement within 1 hour. On the next day, she developed the same clinical symptoms of presentation. Donepezil was discontinued, and clonazepam was started. The patient had a complete recovery from her myoclonus. To the authors’ knowledge, there are six reports of myoclonus secondary to donepezil/galantamine. There is no report of rivastigmine-induced myoclonus. The most frequent presentation was multifocal myoclonus. The management was the discontinuation of the acetylcholinesterase inhibitor. All the individuals recovered within 3 weeks.
In their article “Authorship Disputes in Scholarly Biomedical Publications and Trust in the Research Institution” in the July 2023 issue of RMMJ, Ashkenazi and Olsha examined the association between the prevalence of misattributed authorship and trust in the institution analyzing misconduct in their scholarly publications. The authors, appropriately, include “gift authorship” as one of the three principal deviations from appropriate authorship choices that they examined. In essence, gift or honorary authorship is listing an author on a scholarly publication for which that person’s contribution did not justify assigning authorship. This behavior has become commonplace.
This case study describes the successful short-term outcome of staged minimally invasive pectus excavatum correction and endoscopic mitral valve repair in a patient with severe mitral valve regurgitation and pectus excavatum.
Late-onset nasolacrimal duct obstruction (NLDO) as a result of inflammatory processes causing dacryostenosis is a common entity affecting mostly women. While a few mechanisms have been suggested as contributors to the expression of NLDO, the trigger for the inflammation remains mostly unknown. Familial predilection for this condition has not been previously reported. We present two families with multiple individuals affected with congenital or late-onset NLDO, describe the signs and symptoms of the affected individuals, and explore their medical history for any contributing factors. Family A, spanning four generations, included 7 female patients affected by late-onset NLDO. Family B, spanning two generations, included 8 individuals affected by either congenital or late-onset NLDO. This case series suggests a familial predisposition to NLDO, apparently with an autosomal dominant inheritance pattern. Further studies are needed to elucidate the molecular basis of this genetic predisposition.
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were elaborated to allow authors of such papers to identify quality articles for inclusion in their scholarly work. However, we have identified several issues that point to an over-reliance on the PRISMA guidelines. Firstly, we question the rigor of implementation by authors and the rigor of verification by peer reviewers and editors, and whether they have screened papers to ensure adherence to the PRISMA guidelines. Secondly, we have identified cases where the PRISMA criteria led to as much as 99.97% of the published literature being ignored, suggesting that valid publications meeting these criteria might be at risk of being ignored. Thirdly, we have noted that exclusion is not only a quantitative problem—it is also a qualitative one, since the screening procedure groups all non-conforming literature into one basket. Fourthly, we have noted that seven copies of the PRISMA guidelines exist. This being the case, which one should be cited? To replace over-reliance on PRISMA screening, we encourage authors, peer reviewers, and editors to publish systematic reviews and meta-analyses that respect the dual criteria of scientific plausibility and diversity of included papers.
Objectives: This study aims to investigate the efficacy and outcomes of transurethral resection of the prostate (TURP) in the context of younger male patients.
Methods: Males aged ≤55 who underwent TURP at Rambam Health Care Campus from January 2011 to August 2023 were retrospectively reviewed. Clinicodemographic characteristics, indications for surgery, uroflowmetry, pressure-flow study, and early and late postoperative outcomes were collected. Patients with urethral or bladder abnormalities were excluded. Chi-square and Fisher’s exact tests were employed for bivariate analysis.
Results: Inclusion criteria were met by 58 men who underwent TURP at a median age of 52 years (interquartile range [IQR] 49.5–54). Median prostate size was 35 mL (24.5–56), with median prostate-specific antigen of 1.4 ng/mL (0.65–3.1). A total of 60% of patients used α-blockers, and 19% used 5α-reductase inhibitors pre-surgery. Overall, 54 (93.1%) had severe lower urinary tract symptoms (LUTS), with 34 (59%) being predominantly emptying and 20 (35%) storage. Most surgeries were performed for refractory LUTS in 38 (66%), followed by urinary retention in 16 (28%). At 6 weeks, 57 (98%) patients were catheter-free. The maximum flow rate and residual volume showed significant improvement from 9 mL/s to 21 mL/s (P=0.01), and from 171 mL to 61 mL (P=0.006), respectively. Pathology revealed benign prostatic hyperplasia in 53 (91.4%), and inflammation in 5 (8.5%). A total of 13 auxiliary procedures were required in 12 patients (20.7%) during follow-up: 7 transurethral bladder neck incisions, 3 re-TURP, 1 meatus widening, and 1 patient required artificial urinary sphincter implantation followed by simple cystectomy for end-stage bladder.
Conclusions: In young men, TURP showed short-term gains in flowmetry and catheter removal rates, but a sustained need for subsequent procedures in the long run. In this unique population, patients should be carefully selected, and alternative, less aggressive, interventions should be considered.
Objective: Medical decision-making is often uncertain. The positive predictive value (PPV) and negative predictive value (NPV) are conditional probabilities characterizing diagnostic tests and assessing diagnostic interventions in clinical medicine and epidemiology. The PPV is the probability that a patient has a specified disease, given a positive test result for that disease. The NPV is the probability that a patient does not have the disease, given a negative test result for that disease. Both values depend on disease incidence or prevalence, which may be highly uncertain for unfamiliar diseases, epidemics, etc. Probability distributions for this uncertainty are usually unavailable. We develop a non-probabilistic method for interpreting PPV and NPV with uncertain prevalence.
Methods: Uncertainty in PPV and NPV is managed with the non-probabilistic concept of robustness in info-gap theory. Robustness of PPV or NPV estimates is the greatest uncertainty (in prevalence) at which the estimate’s error is acceptable.
Results: Four properties are demonstrated. Zeroing: best estimates of PPV or NPV have no robustness to uncertain prevalence; best estimates are unreliable for interpreting diagnostic tests. Trade-off: robustness increases as error increases; this trade-off identifies robustly reliable error in PPV or NPV. Preference reversal: sometimes sub-optimal PPV or NPV estimates are more robust to uncertain incidence or prevalence than optimal estimates, motivating reversal of preference from the putative optimum to the sub-optimal estimate. Trade-off between specificity and robustness to uncertainty: the robustness increases as test-specificity decreases. These four properties underlie the interpretation of PPV and NPV.
Conclusions: The PPV and NPV assess diagnostic tests, but are sensitive to lack of knowledge that generates non-probabilistic uncertain prevalence and must be supplemented with robustness analysis. When uncertainties abound, as with unfamiliar diseases, assessing robustness is critical to avoiding erroneous decisions.
Background and Objective: Chronic low back pain disability (CLBPD) is a syndrome that includes pain, disability, emotional impairments, and social problems. The study was conducted to examine the effect of an inpatient rehabilitation program on the performance of everyday life tasks (daily activities), and report on pain in CLBPD patients with primary activities of daily living (ADL) deficits.
Methods: In a retrospective cohort study, demographic and clinical data were retrieved from records of inpatients admitted consecutively to the program. Scores of the Spinal Pain Independence Measure (SPIM) and of changes in reported pain levels were used to assess improvement in the performance of daily activities and pain reduction. T-tests were used to assess the significance of score changes. Spearman’s correlations and analysis of variance were used to assess relationships of SPIM gain and affecting factors.
Results: Ninety-nine patients were included. Daily task performance improved in 71 patients (71.7%). The SPIM score increased from 48.7 (SD 16.3) at admission to the rehabilitation program to 57.8 (SD 12.5) at discharge (P<0.001). The SPIM score at admission negatively affected SPIM gain (P<0.001). The SPIM gain was significant for admission SPIM scores of 50 or lower (P<0.05), but differences in SPIM scores were not as noticeable for patients with admission SPIM scores above 50. Relief in pain was reported in 59 patients (59.6%) and was not associated with function.
Conclusions: The multidisciplinary rehabilitation program, which improved function and provided limited pain relief in inpatients with CLBPD primary ADL deficits, can be effective for the most severe CLBPD cases.
IgG4-related disease (IgG4-RD) is a rare illness with inflammatory and fibrotic changes in affected organs such as pancreas, thyroid, salivary or lacrimal glands, and retroperitoneal space; rarely other organs may be involved. IgG4-related breast disease (IgG4-BD) is very rare and generally presents as a lump or mastitis. IgG4-BD as a presenting feature of IgG4-RD is extremely rare. Hence, this paper reviews the known (n=48) IgG-BD cases reported in the literature to date. The majority of cases were diagnosed on routine mammography or during assessment for other clinically significant features. The absence of a lump border, and especially the absence of calcifications on ultrasonography, mammography, or computed tomography, is typical for IgG4-BD. Characteristic IgG4-BD pathological findings were dense lymphoplasmacytic infiltration with stromal fibrosis, and more than 10% IgG4+ plasma cells/high-power field (HPF); the mean percentage of IgG4+/IgG+ plasma cells was 54.2%, and only one-third of the patients had all “classical” signs of IgG4-BD including storiform fibrosis and obliterative phlebitis. Most of the cases had a benign course and responded to surgical excision with or without steroid therapy.
Coronavirus disease-19 (COVID-19) is a pandemic infectious disease caused by a novel coronavirus. Infection can result in a wide range of clinical outcomes, from an asymptomatic condition to severe bilateral pneumonia and life-threatening conditions. Diagnosis is based on the combination of a history of exposure, clinical presentation, and real-time polymerase chain reaction (RT-PCR) assays. In endemic areas, imaging tests including computed tomography (CT), chest X-ray (CXR), and ultrasound (US) have been included in the diagnostic workup. Multiple and peripheral areas of parenchymal injury is the hallmark of COVID-19 lung infection, seen as ground-glass opacification and consolidation on CT, as hazy opacities on CXR, and as multiple B-lines and subpleural consolidations on US. Of these modalities, CT has the best sensitivity and specificity, while CXR has moderate sensitivity and unknown specificity. Both CT and CXR involve ionizing radiation, increase the risk of cross-infection, and require a long sterilization time. Ultrasound is the only modality used by clinicians. Early reports have shown promising results, comparable to CT. With high availability, the lowest risk of cross-infection, and a rapid sterilization process, US may potentially become the primary imaging tool for COVID-19 pulmonary injury. Lung US training programs are needed to provide clinicians with the ability to better implement this technique.
