Review
INTRODUCTION
Anterior ischemic optic neuropathy (AION) can mimic glaucoma and consequently cause difficulties in differential diagnosis. The purpose of this paper was to summarize differences in diagnostic tests that can help perform a correct diagnosis.
METHODS
The search strategy was performed according to the PRISMA 2009 guidelines, and four databases were used: MEDLINE, Embase, Web of Science, and Cochrane. Totally, 772 references were eligible; 39 were included after screening with respect to inclusion criteria that included English language and published in the 20 years before search date.
RESULTS
Ninety percent (n = 35) of included studies used optical coherence tomography (OCT). Glaucomatous eyes had a significantly greater cup area, volume and depth, cup-to-disk ratio, a lower rim volume and area, and a thinner Bruch's membrane opening-minimum rim width. Retinal nerve fiber layer (RNFL) thinning in glaucomatous eyes occurred primarily at the superotemporal, inferotemporal, and inferonasal sectors, while AION eyes demonstrated mostly superonasal thinning. Glaucoma eyes showed greater macular ganglion cell layer thickness, except at the inferotemporal sector. OCT angiography measurements demonstrated a significant decrease in superficial and deep macular vessel density (VD) in glaucoma compared to AION with similar degree of visual field damage; the parapapillary choroidal VD was spared in AION eyes compared to glaucomatous eyes.
CONCLUSION
By use of OCT imaging, optic nerve head parameters seem most informative to distinguish between glaucoma and AION. Although both diseases affect the RNFL thickness, it seems to do so in different sectors. Differences in structure and vascularity of the macula can also help in making the differential diagnosis.

Review
Olfactory dysfunction is a prevalent non-motor symptom in Parkinson's disease (PD), affecting approximately 65-90% of subjects. PD patients may also report odor perception in the absence of any external source, often referred to as olfactory hallucinations (OHs) or phantosmia. This study aims to explore the current understanding of OHs in PD and offer a comprehensive overview of their prevalence and characteristics. We conducted a systematic search of the literature published on PubMed from inception to July 2023 regarding OHs in PD, following PRISMA guidelines. From the 2875 studies identified through database searching, 29 studies fulfilled the necessary criteria and underwent data extraction. The frequency of OHs in PD patients varies widely, ranging from 0.5% to 18.2%, with female prevalence ranging from 36% to 75% of the patients. Olfactory experiences may vary widely, ranging from pleasant scents to unpleasant odors. Several studies have indicated the concurrent presence of other types of hallucinations alongside phantosmia, especially visual and auditory hallucinations. OHs in PD are a type of hallucination that has been largely overlooked. To gain a deeper understanding of OHs in PD patients, the next crucial step should involve the development and validation of a dedicated questionnaire.

Review
The vestibular system plays a fundamental role in body orientation, posture control, and spatial and body motion perception, as well as in gaze and eye movements. We aimed to review the current knowledge regarding the location of the cortical and subcortical areas, implicated in the processing of vestibular stimuli. The search was performed in PubMed and Scopus. We focused on studies reporting on vestibular manifestations after electrical cortical stimulation. A total of 16 studies were finally included. Two main types of vestibular responses were elicited, including vertigo and perception of body movement. The latter could be either rotatory or translational. Electrical stimulation of the temporal structures elicited mainly vertigo, while stimulation of the parietal lobe was associated with perceptions of body movement. Stimulation of the occipital lobe produced vertigo with visual manifestations. There was evidence that the vestibular responses became more robust with increasing current intensity. Low-frequency stimulation proved to be more effective than high-frequency in eliciting vestibular responses. Numerous non-vestibular responses were recorded after stimulation of the vestibular cortex, including somatosensory, viscero-sensory, and emotional manifestations. Newer imaging modalities such as functional MRI (fMRI), Positron Emission Tomography (PET), SPECT, and near infra-red spectroscopy (NIRS) can provide useful information regarding localization of the vestibular cortex.

Review
Understanding predictors of pain associated with paediatric dental procedures could play an important role in preventing loss of cooperation, which often leads to the procedure having to be performed under general anaesthesia. We aimed to identify predictors of intra-operative and post-operative pain associated with routine dental procedures in children. A systematic review of observational studies was performed using electronic searches on MEDLINE, EMBASE, PsycINFO, Global Health via OVID, PubMed, Scopus, and SciELO. The NIH Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was used to evaluate the quality of the included studies, which were meta-analysed to estimate the impact of dental procedures and anxiety on children's pain perception. A meta-regression analysis was also performed to determine the relative effect of predictors on children's pain perception measured as mean differences on a visual analogue scale (VAS). The search identified 532 articles; 53 were retrieved for full-text screening; 6 studies were included in the review; and 4 were eligible for the meta-analysis. The meta-analysis showed the types of procedures that predicted intra-operative pain, with dental extractions being the most painful (Mean VAS Difference [MD] 46.51 mm, 95% confidence interval [CI] 40.40 to 52.62 mm). The meta-regression showed that pain scores for dental extractions were significantly higher than polishing (the least painful procedure (reference category)) by VAS MD = 23.80 mm (95% CI 5.13-42.46 mm, -value = 0.012). It also showed that highly anxious children reported significantly higher pain scores during dental procedures by a 12.31 mm MD VAS score (95% CI 5.23-19.40 mm, -value = 0.001) compared to those with low anxiety levels. This systematic review demonstrates that the strongest predictors of intra-operative pain associated with paediatric dental procedures are dental extractions followed by drilling. Children with high anxiety also reported more pain for similar procedures. Tailoring interventions to reduce pain associated with paediatric dental procedures should be a priority for future research, as reducing pain can impact compliance and could reduce the need for general anaesthesia in dental treatment.

Review
Neurological rehabilitation is a physician-supervised programme for individuals with nervous system diseases, injuries or disorders. Neurological rehabilitation, also known as neurorehabilitation, is part of the rehabilitation process that improves function, reduces severity and enhances a patient's well-being. Because neurological injuries occur in the brain, spine and nerves, affecting multiple body parts including organs, blood vessels, muscles and bones, rehabilitation requires a multidisciplinary approach. This study conducted a systematic literature review (SLR) on the use of mobile game in neurorehabilitation. The steps undertaken in the literature review included the collection, identification, categorisation, summarisation and synthesis of relevant studies in the research domain. A total of 50 related articles were reviewed. The study identified that the effects on cognitive skills, handgrip strength, memory, attention, visuospatial abilities, executive function tasks, motor functionality, and improvements in balance, visual perception, and functional mobility are impacts of the use of mobile games in neurological rehabilitation. Furthermore, several research challenges and recommendations for future research were identified.

The primary aim of this study was to systematically review and meta-analyze the impact of sensorimotor and proprioceptive exercises on balance in older adults. We also sought to define how researchers describe proprioceptive and sensory-motor training and their respective protocols. The review was conducted following the PRISMA guidelines, with searches performed in March 2023. Both authors carried out independent searches using the PubMed and PEDro databases. From a total of 320 identified records, 12 studies were deemed eligible for meta-analysis after screening and removal of duplicates. The average PEDro score was 5.11 ± 1.11 indicating overall fair quality of studies. Common outcome measures included the Berg balance scale, Timed up and go test, Tinetti balance scale, Functional reach test and various single-leg stance tests. All outcomes were significantly improved by the interventions (standard mean difference = 0.65 - 1.29), with little difference between proprioceptive and sensorimotor training. However, the quality of evidence ranged from "very low" to "low" based on GRADE guidelines, suggesting further high-quality studies are needed. This review underscores the potential benefits of sensorimotor and proprioceptive exercises for enhancing balance in older adults, while also highlighting the ambiguity and inconsistency regarding the usage of the terms proprioceptive and sensorimotor training.

Meta-Analysis
Knowledge, attitudes and prevention practices related to dog-mediated rabies in Ethiopia: a systematic review and meta-analysis of observational epidemiological studies from inception to 2023.
BACKGROUND
Rabies is a horrific and neglected zoonotic disease that kills thousands of people worldwide each year and continues to pose threats to public health. Prevention and control of dog-transmitted rabies require mapping the level of understanding, perception, and existing practices to minimize its impacts on health. Therefore, we undertook this systematic review and meta-analysis to pool evidence from available data on knowledge, attitudes, and prevention practices regarding the disease from studies conducted in various areas of Ethiopia.
METHODS
Articles were searched in electronic bibliographic medical databases such as the Excerpta Medica database, PubMed, Web of Science, African Journals Online, Google Scholar, and Scopus. We used Microsoft Excel spreadsheets and STATA software version 16 for the data excerption and analysis, respectively. The variability among studies was evaluated via Higgins and Thompson's statistics and the test (significant at ≤ 0.1). The Dersimonian and Laird random-effect meta-analysis model was used to estimate the pooled effect at a 95% uncertainty interval (UI). Visual inspection and Egger's test (significant at ≤ 0.05) were used to identify the presence of small-study effects.
RESULTS
The search identified 1,249 electronic records. Of them, 27 studies involving 11,150 participants met the inclusion criteria. The pooled prevalence of a good level of knowledge was 62.24% (95% UI: 48.56, 75.92). Furthermore, the pooled prevalence of a favorable level of attitudes towards rabies and a good level of rabies prevention practices was only 56.73% (95% UI: 47.16, 66.29) and 52.73% (95% UI: 43.32, 62.15), respectively.
CONCLUSION
The study revealed credible gaps in attitudes and prevention practices, though some level of knowledge about dog-mediated rabies was demonstrated. Therefore, we call for country-wide cross-sectoral collaboration to allow for the realization of a global elimination strategy for dog-mediated human rabies.

Review
Sensory Substitution (SS) allows the elaboration of information via non preferential sensory modalities. This phenomenon occurs in robotic-assisted surgery (RAS), in which haptic feedback is lacking. It has been suggested that SS could sustain surgeons' proficiency by means of visual clues for inferring tactile information, that also promotes the feeling of haptic phantom sensations. A critical role in reaching a good performance in procedural tasks is also sustained by the Sense of Embodiment (SE), that is, the capacity to integrate objects into subjective bodily self-representation. As SE is enhanced by haptic sensations, we hypothesize a role of SS in promoting SE in RAS. Accordingly, the goal of this systematic review is to summarize the evidence pertaining the study of SS in RAS in order to highlight the impact on the performance, and to identify a mediating role of the SE in increasing dexterity in RAS. Eight studies selected from the MEDLINE and Scopus® databases met inclusion criteria for a qualitative synthesis. Results indicated that haptic to other modalities SS enhanced force consistency and accuracy, and decreased surgeon fatigue. Expert surgeons, as compared to novices, showed a better natural SS processing, testified by a proficient performance with and without SS aids. No studies investigated the mediating role of SE. These findings indicate that SS is subjected to learning and memory processes that help surgeons to rapidly derive haptic-correlates from visual clues, which are highly required for a good performance. Also, the higher ability of doing SS and the associated perception of haptic sensations might increase multisensory integration, which might sustain performance.

BACKGROUND
Chronic Low Back Pain (CLBP) is a prevalent global health issue, leading to prolonged discomfort and functional limitations. Hot spring hydrotherapy, which utilizes mineral-rich, warm spring water, offers a unique physical therapy that holds promise in alleviating CLBP symptoms.
OBJECTIVE
This meta-analysis aims to assess the effectiveness of hot spring hydrotherapy in improving CLBP symptoms, encompassing pain intensity, functional disability, quality of life, and medication usage.
METHODS
A systematic review and meta-analysis were conducted by searching relevant literature in multiple databases. Included studies compared hot spring hydrotherapy with control interventions or other treatments. Standardized mean differences (SMD) with 95% confidence intervals (CI) were calculated for pain intensity, functional disability, medication usage, and quality of life.
RESULTS
A total of 16 studies met the inclusion criteria, involving 1656 participants with chronic low back pain across various countries. The meta-analysis demonstrated that hot spring hydrotherapy was effective in reducing pain intensity (SMD = -0.901, 95% CI [-1.777, -0.025], < 0.05) and improving functional disability (SMD = -3.236, 95% CI [-4.898, -1.575], < 0.0001) in CLBP patients. Hot spring hydrotherapy also resulted in a significant reduction in medication usage ( < 0.05). Subgroup analysis showed that the effects of hot spring hydrotherapy were more pronounced in patients aged 60 and above, while no significant differences were observed in patients below 60 years of age, single hot Spring Hydrotherapy help improve patients' quality of life.
CONCLUSION
Hot spring hydrotherapy is an effective intervention for improving CLBP symptoms, including pain intensity, functional disability, and medication usage. It is particularly beneficial for CLBP patients aged 60 and above. These findings support the integration of hot spring hydrotherapy into the treatment approach for CLBP, although further research is needed to determine its efficacy in younger patients and to explore the underlying mechanisms of its therapeutic effects.

Review
Rhythmic visual stimulation (RVS), the periodic presentation of visual stimuli to elicit a rhythmic brain response, is increasingly applied to reveal insights into early neurocognitive development. Our systematic review identified 69 studies applying RVS in 0- to 6-year-olds. RVS has long been used to study the development of the visual system and applications have more recently been expanded to uncover higher cognitive functions in the developing brain, including overt and covert attention, face and object perception, numeral cognition, and predictive processing. These insights are owed to the unique benefits of RVS, such as the targeted frequency and stimulus-specific neural responses, as well as a remarkable signal-to-noise ratio. Yet, neural mechanisms underlying the RVS response are still poorly understood. We discuss critical challenges and avenues for future research, and the unique potentials the method holds. With this review, we provide a resource for researchers interested in the breadth of developmental RVS research and hope to inspire the future use of this cutting-edge method in developmental cognitive neuroscience.
