Prevalence of autism spectrum disorder in Indian children: A systematic review and meta-analysis
Anil Chauhan, Jitendra K Sahu, Nishant Jaiswal, Kiran Kumar, Amit Agarwal, Jasleen Kaur, Sukhmanjeet Singh, Meenu Singh
January-February 2019, 67(1):100-104
DOI:10.4103/0028-3886.253970  PMID:30860104
Background: Autism spectrum disorder (ASD) is a developmental disability and is of public health importance. It affects not only the child and the family. It also has direct and indirect cost implications on the nation that are incurred in providing health care, support for education, and rehabilitative services. There is a lack of evidence-based estimate of the population prevalence of ASD in India. Therefore, this systematic review was aimed at determining the prevalence of ASD in the Indian population. Materials and Methods: We conducted a systematic review and meta-analysis of the published studies evaluating the prevalence of ASD in the community setting. A search within the published literature was conducted from different databases (PubMed, OvidSP, and EMBASE). The analysis of data was done using STATA MP12 (StataCorp, College Station, TX, USA). Results: Four studies were included in this systematic review. Of the four included studies, one had studied both urban and rural populations, and the other three had studied the urban populations only. The study from the rural setting showed a pooled percentage prevalence of 0.11 [95% confidence interval (CI) 0.01–0.20] in children aged 1-18 years; and, four studies conducted in the urban setting showed a pooled percentage prevalence of 0.09 (95% CI 0.02–0.16) in children aged 0-15 years. Conclusion: The scarcity of high-quality population-based epidemiological studies on ASD in India highlights an urgent need to study the burden of ASD in India. The proper acquisition of data related to the prevailing burden of ASD in India would lead to a better development of rehabilitative services in our country.

Shunt migration in ventriculoperitoneal shunting: A comprehensive review of literature
LS Harischandra, Anurag Sharma, Sandip Chatterjee
January-February 2019, 67(1):85-99
DOI:10.4103/0028-3886.253968  PMID:30860103
Ventriculoperitoneal shunts are one of the commonest surgical procedures performed in neurosurgery. Complications of this procedure include mechanical complications and nonmechanical ones. The most distressing mechanical complication is shunt migration, and often when this occurs, it becomes difficult to work out the mechanism and the management protocol. This review is designed to answer questions regarding management details of this unfortunate complication, and also seeks to identify the causes

Bibliometric analysis of the top-cited articles on idiopathic intracranial hypertension
Yavuz Samanci, Bedia Samanci, Erdi Sahin
January-February 2019, 67(1):78-84
DOI:10.4103/0028-3886.253969  PMID:30860102
Objective: To identify and characterize the top-cited articles on idiopathic intracranial hypertension. Methods: We used “Web of Science database” to identify the top-cited articles published between the years of 1975-2017. The articles were evaluated using citation count and other factors that have an effect on the citation count. Results: The search yielded a total of 2,141 articles and the most frequently cited articles received between 58-476 citations. Most articles were published between the years 1990-1999. The most popular study design involved natural history studies. USA ranked first in productivity with 72 articles and the leading institution was University of Iowa. The journal “Neurology” published the greatest number of articles. In assessing the specialties, neurology contributed to 32% of top 100 articles. There was no correlation between the citation count and number of references, years since publication, number of authors, authors' H-index, and number of institutions that had collaborated. There were positive correlations between the citation count and journal impact factor, Scimago journal rank and journal source-normalized impact per paper values. While descriptive keywords were more frequent between 1980s and 1990s, keywords describing surgical management options such as “nerve sheath decompression” and “cerebrospinal-fluid diversion” were top-listed keywords after the year 2000. Conclusions: Our study can help researchers identify the most significant and impactful articles on idiopathic intracranial hypertension, as well as to provide insight into the most noteworthy scientific trends and to visualize future research needs of the topic.

Ictal FDGPET and SPECT in hemifacial seizures due to cerebellar epilepsy—Case report
Swapan Gupta, Sita Jayalakshmi, Lokesh Lingappa, Ramesh Konanki, Sudhindra Vooturi, Pushpalatha Sudhakar, Manas Panigrahi
January-February 2019, 67(1):169-172
DOI:10.4103/0028-3886.253622  PMID:30860118
The role of cerebellum in seizure generation is debatable. Semiology and electroencephalography (EEG) findings are non-specific and sometimes misleading, posing further difficulty in proving the epileptogenicity in pre-surgical workup. We report two cases of cerebellar lesions who presented with hemifacial seizures since the neonatal period and were refractory to antiepileptic drugs (AEDs). Both inter-ictal and ictal EEGs were non-contributory. Magnetic resonance imaging (MRI) showed a lesion in the cerebellum, in proximity to cerebellar peduncle in both the patients. (18) F-fluorodeoxyglucose–positron emission tomography (FDG-PET) and ictal single photon emission computed tomography (SPECT) showed focal hypermetabolism and hyperperfusion respectively, corresponding to the lesion on MRI in both the cases. Intraoperative electrocorticography showed rhythmic spikes confirming the epileptogenic nature of the lesion. Both patients were operated with a favorable surgical outcome. Histopathology was suggestive of a ganglioglioma in one child and a low-grade glioma in the other. Both cases illustrate that FDG-PET and SPECT can act as surrogate markers for invasive recordings to prove the epileptogenicity of cerebellar lesions, especially in resource limited settings.

Cerebrospinal fluid rhinorrhea from the lateral recess of sphenoid sinus: More to it than meets the eye
Gopikrishnan Rajasekar, Prakash Nair, Mathew Abraham, Vinod Felix, Arunkumar Karthikayan
January-February 2019, 67(1):201-206
DOI:10.4103/0028-3886.253634  PMID:30860122
Background: Cerebrospinal fluid (CSF) leak from the lateral recess of the sphenoid sinus is rare when compared to leaks from other sites. The extended endonasal approach along with a transpterygoid extension provides adequate exposure for repair of these defects. Materials and Methods: We retrospectively analyzed a series of seven patients who underwent eight transpterygoid approaches for repair of the CSF leak from the lateral recess of the sphenoid sinus. We analyzed the patient characteristics, site of leaks, type of repair done, and presence of increased intracranial pressure (ICP) in these individuals. Results: Seven patients underwent eight transpterygoid approaches for CSF leaks from the lateral recess of the sphenoid sinus. The leak was bilateral in one patient. The materials used for repair consisted of fat, fascia lata, free mucosal flap or a vascularised nasoseptal flap, and fibrin glue. Evidence of increased ICP was found in five of the seven patients. CSF diversion was needed in three of the seven patients (two ventriculoperitoneal shunt and one thecoperitoneal shunt). Conclusion: Endoscopic endonasal transpterygoid approach provides an excellent visualization of the skull-base defect and facilitates adequate instrument manipulation within the corridor, allowing successful repair of the defect with low rates of recurrence. Increased ICP can have a role in causing spontaneous CSF rhinorrhea from this location.

Variations in electroencephalography with mobile phone usage in medical students
Kanak Parmar, Ruchika Tandon, Neeraj Kumar, Ravindra Kumar Garg
January-February 2019, 67(1):235-241
DOI:10.4103/0028-3886.253610  PMID:30860126
Background: Electromagnetic fields (EMFs) emitted by cellular telephones may cause neurological ill effects like cognitive dysfunction, emotional instability, and even brain tumors. Slowing of brain activity on electroencephalography (EEG) has been shown. However, these findings need further validation. Aims: EEG changes and adverse effects experienced following cell-phone use were studied. Settings and Design: The study was conducted in the Department of Neurology of a tertiary care university hospital in India on North Indian students of the University, from August 2017 to October 2017. Materials and Methods: Twenty-one students underwent video-EEG recording before and after application of Samsung GT-56312 dual SIM smart phone in switched off, switched on, and switched on mode with conversation. Statistical Analysis Used: Average EEG frequencies and amplitudes were calculated for different brain regions. Chi-square tests and t-tests were used for comparison between variables. Results: The mean age of 7 (33.3%) male and 14 (66.7%) female subjects was 20.76 ± 1.48 years. The average EEG frequencies following mobile phone application with conversation were higher and the amplitudes lower than the baseline values. Frequencies were greater on the right side. Slow waves were detected in the frontal region in 38.1%, in the parietal region in 33.3%, in the occipital and temporal region in 19.1%; and, generalized slow waves were seen in 9.5% students. During the experiment, 23.8% experienced headache, 19% experienced irritation, and 9.5% felt drowsy. Headache and loss of concentration (33.3%), sleep disturbances (28.6%), and fatigue (19%) were frequent in daily life. Conclusions: Experimental application of mobile phones may lead to some EEG changes and certain ill effects on the well-being. Hence, prolonged use of these gadgets warrants caution.

The term 'scientist' was coined to describe Mary Somerville (1780-1872) as her contributions to astronomy commanded recognition of her excellence in science. Up to then, the term 'man of science' had been in use. In fields traditionally considered the province of males, the entry of women was viewed with consternation, apprehension and alarm. Resistance was instinctive in most leading scientists. This attitude was strengthened by illogical and pseudoscientific statements on the frailty of women. The pioneers blazing trails in medicine for their sisters to follow braved ridicule, hostility, and discrimination. At times they used subterfuge. The example of Dr. James Barry (Margaret Ann Bulkley) is well-known. Thanks to them, we now have nationally and internationally eminent scientists from the gentler sex, and some of them in commanding positions. The neurosciences developed in India as a result of the efforts made by pioneer neurosurgeons such as Drs. Jacob Chandy (Vellore), B. Ramamurthi (Madras), R.G. Ginde (Bombay), Dr. Prakash N. Tandon (New Delhi) and neurophysicians such as Drs. Baldev Singh (New Delhi), T.K. Ghosh (Calcutta) and Noshir H. Wadia (Mumbai). They and others such as Drs. V.R. Khanolkar, Darab K. Dastur, B.K. Bachhawat and Obaid Siddiqui encouraged individuals like Dr. Vimla Virmani, Dr. Devika Nag, Dr. T.S. Kanaka and Dr. Gourie Devi in the clinical neurosciences and Drs. Kamal Ranadive, V.S. Lalitha, Veronica Rodrigues and Gomathy Gopinath in the basic neurosciences. Two eminent neuroscientists from abroad (Drs. Nancy Kopell and Indira Raman), and three from India (Drs. Vijaylakshmi Ravindranath, Chitra Sarkar and Vidita Vaidya) have been chosen by me as representatives and their careers, contributions and views on discrimination against women in science discussed in brief. (This is not to deny outstanding work by others but limitations of space have made this choice necessary.) The factors favouring the blossoming of women in science include encouraging and stimulating parents, a conducive environment at home and mentors. A compelling drive to excel, hard work and sincerity are crucial to success. Nasty forms of experiences demoralise women. Sexual harassment by seniors and colleagues in the laboratory and elsewhere can lead to the victim leaving the field altogether. Discrimination in selection, promotion and publication lower morale and impact output in terms of research and contributions to journals and books. Suggestions made by the five eminent neuroscientists named above to liberate women from such negative behaviour by males are presented. The Indian Women Scientists' Association is playing an important role in helping their members, making their work known to society and generally empowering them. Since unity strengthens, collaborative activities with other similar organisations will augment efficacy. One such organisation is the much older Association of Medical Women of India.

Context: A brain magnetic resonanace imaging (MRI) atlas plays an important role in many neuroimage analysis tasks as it provides an atlas with a standard coordinate system which is needed for spatial normalization of a brain MRI. Ideally, this atlas should be as near to the average brain of the population being studied as possible. Aims: The aim of this study is to construct and validate the Indian brain MRI atlas of young Indian population and the corresponding structure probability maps. Settings and Design: This was a population-specific atlas generation and validation process. Materials and Methods: 100 young healthy adults (M/F = 50/50), aged 21–30 years, were recruited for the study. Three different 1.5-T scanners were used for image acquisition. The atlas and structure maps were created using nonrigid groupwise registration and label-transfer techniques. Comparison and Validation: The generated atlas was compared against other atlases to study the population-specific trends. Results: The atlas-based comparison indicated a signifi cant difference between the global size of Indian and Caucasian brains. This difference was noteworthy for all three global measures, namely, length, width, and height. Such a comparison with the Chinese and Korean brain templates indicate all 3 to be comparable in length but signifi cantly different (smaller) in terms of height and width. Conclusions: The findings confirm that there is significant difference in brain morphology between Indian, Chinese, and Caucasian populations.

Introduction: Recent advances in the molecular biology of adult diffuse gliomas have brought about a paradigm shift in their diagnostic criteria, as witnessed in the World Health Organization (WHO) 2016 guidelines for central nervous system tumors. It is now mandatory to perform several molecular tests to reach a definitive integrated diagnosis in most of the cases. This comes with additional cost and higher turnaround time, which is not always affordable in developing countries like India. In addition, the non-uniform distribution of advanced research and diagnostic testing centers adds to the difficulty. Methods: The Indian Society of Neuro-oncology (ISNO) multidisciplinary expert panel consisting of neuropathologists, neurosurgeons, and radiation/medical oncologists convened to prepare the national consensus guidelines for approach to diagnosis of adult diffuse gliomas. Results: Algorithms for arriving at an integrated diagnosis of adult diffuse gliomas predominantly using immunohistochemistry and with minimum possible additional molecular testing were agreed upon, thus addressing the problems of cost, accessibility, and turnaround time. Mandatory and optional tests were proposed for each case scenario. Conclusion: This document represents the consensus of the various neuro-oncology disciplines involved in diagnosis and management of patients with adult diffuse gliomas. The article reflects a practical adaptation of the WHO recommendations to suit a resource constrained setup.

Purpose: Long standing temporal lobe epilepsy (TLE) causes cerebral insult and results in elevated brain injury biomarkers, S100b and neuron specific enolase (NSE). Surgery for TLE, has the potential to cause additional cerebral insult. Dexmedetomidine is postulated to have neuroprotective effects. The aim of this study was to assess the effect of intraoperative dexmedetomidine on S100b and NSE during TLE surgery. Materials and Methods: 19 consenting adult patients with TLE undergoing anteromedial temporal lobectomy were enrolled and divided into two groups. Patients in Group D (n = 9) received dexmedetomidine whereas patients in Group C (n = 10) received saline as placebo in addition to the standard anaesthesia technique. Blood samples of these patients were drawn, before induction of anaesthesia, at the end of surgery, as well at 24 hours and 48 hours postoperatively, and analysed for serum S100b and NSE. Results: The demographic and clinical profile was comparable in both the groups. The baseline S100b in group C and group D was 66.7 ± 26.5 pg/ml and 34.3 ± 21.7 pg/ml (P = 0.013) respectively. After adjustment for the baseline, the overall value of S100b was 71.0 ± 39.8 pg/ml and 40.5 ± 22.5 pg/ml (P = 0.002) in the control and study group, respectively. The values of S100b (79.3 ± 53.6 pg/ml) [P = 0.017] were highest at 24 hours postoperatively. The mean value of NSE in the control and study group was 32.8 ± 43.4 ng/ml (log 3.0 ± 0.1) and 13.51 ± 9.12 ng/ml (log 2.42 ± 0.60), respectively. The value of NSE in both the groups was comparable at different time points. Conclusions: Lower perioperative values of S100b were observed in patients who received intraoperative dexmedetomidine. Dexmedetomidine may play a role in cerebroprotection during epilepsy surgery.

Objective: To describe the clinical profile, treatment response and predictors of outcome in patients with primary angiitis of the central nervous system (PACNS) from a single tertiary care center. Methodology: Retrospective analysis of consecutive patients diagnosed with PACNS from January 2000 to December 2015. Outcome was defined as poor when the 6-month modified Rankin scale (mRS) was ≥3. Results: The median age of the 45 patients included in this study was 36 (range 19-70) years at disease onset and 31 (68.9%) were males. The initial presentation was ischemic stroke in 15 (33.3%), hemorrhagic stroke in 4 (8.9%), headache in 11 (24.4%), seizures in 8 (17.8%) and cognitive dysfunction in 5 (11.1%) patients. Diagnosis was confirmed by a four vessel cerebral digital subtraction angiogram (DSA), biopsy and by both biopsy and DSA in 26 (57.8%), 15 (33.3%) and 4 (8.9%) patients, respectively. All patients received glucocorticoids and 14 patients received in addition either cyclophosphamide or azathioprine as their first treatment. The median duration of follow-up was 33.1 (0.7-356) months. A poor 6-month outcome was observed in 12 (26.7%) patients. Relapse occurred in 25 (55.6%) patients and 7 (15.6%) died. Predictors of a poor outcome consisted of cognitive dysfunction at diagnosis (80% vs 20%; P = 0.014) and NIHSS ≥5 (62.5% vs 37.5%; P <.0005). None of the patients with a normal EEG had a poor outcome (P = 0.046). Predictors of relapse were a higher NIHSS at admission (P =.032) and a normal DSA (P = 0.002). Conclusion: In this cohort, severe deficits and cognitive symptoms at onset and an abnormal EEG were associated with a poor 6-month outcome.

3D-Double-Inversion recovery detects perilesional gliosis better than 3D-FLAIR and postcontrast T1 imaging in calcified neurocysticercosis
Jitender Saini, Pradeep Kumar Gupta, Praveen Gupta, Ravi Yadav, Nishtha Yadav, Rakesh Kumar Gupta
January-February 2019, 67(1):136-141
DOI:10.4103/0028-3886.253614  PMID:30860112
Background: Perilesional gliosis is an important substrate for seizures in patients harboring a calcified neurocysticercosis (NCC) lesion and magnetic resonance imaging (MRI) is useful for evaluating gliosis. Aims: The purpose of this study was to evaluate the usefulness of double-inversion recovery (DIR) sequence for identifying perilesional gliosis. Settings and Design: Hospital-based cross-sectional study. Methods and Materials: Forty-five patients with seizures were included in this study and a total of 88 calcified lesions identified on susceptibility weighted imaging (SWI) were evaluated on 3D-fluid attenuating inversion recovery (FLAIR), 3D-DIR, and 3D-postcontrast T1-weighted imaging on a 3T MRI for the presence of perilesional signal changes/enhancement. Perilesional signal was rated on a semiquantitative scale from grade 0 to 2 by independent raters. Statistical Analysis Used: Friedman, Wilcoxon signed rank, and Kappa tests were used. Results: 3D-DIR sequence performed better than both 3D-FLAIR and postcontrast 3D-T1W sequences as more number of lesions showed perilesional signal change on DIR sequence. DIR sequence showed perilesional signal abnormality in 24 lesions in which 3D-FLAIR was normal, whereas in another 18 lesions, it demonstrated perilesional signal changes better than 3D-FLAIR. In only three lesions, FLAIR was found to be superior to DIR sequence, whereas postcontrast T1W images showed rim enhancement in five cases where no perilesional signal change was seen on FLAIR/DIR sequences. Conclusions: Combining 3D-DIR with 3D-FLAIR, and postcontrast 3D-T1W sequences is beneficial for evaluation of calcified NCC lesions and 3D-DIR sequence is better than other two sequences for perilesional signal abnormalities.

Introduction: Anterior and anterolaterally situated foramen magnum meningiomas are a technically complex subgroup of meningiomas. The need for an extensive exposure and bone work and their complex anatomy make them a difficult and challenging group of tumors to resect. The bone work has ranged from an extensive condylar resection to condylar preserving exposures. In this paper, we present our experience with condylar preserving or minimal condylar resection based approaches to these tumors. Materials and Methods: All patients who underwent surgical resection of anterior and anterolaterally situated foramen magnum meningiomas were included in the analysis. The study period was more than 10 years from 2005 to 2015 at our institute; a tertiary referral centre in India. The records along with demographic profile, clinico-radiological features, surgical strategies, outcomes as well as mortality and morbidity were analysed. Results: There were a total of 20 patients (9 males and 11 females) who were operated during the study period. The average age was 36.7 years. In 16 patients, gross-total or near-total resection could be achieved, four patients underwent subtotal resection. Eight patients had fresh morbidity in the form of new motor deficits, pseudomeningocele formation, worsening of the lower cranial nerve functions or post-operative adhesions leading to syrinx formation. The follow-up ranged from 6 months to 140 months. Conclusion: Foramen magnum meningiomas are an eminently treatable group of tumors. Condylar preservation provides a good visualization, while helping to preserve joint stability and in avoiding instrumental stabilization.

DOI:10.4103/0028-3886.253631  PMID:30860114
Background: The goal of surgery in case of a large vestibular schwannoma is complete excision of tumor and preservation of facial nerve function. The identification and preservation of facial nerve is very difficult during surgery, particularly in case of large tumors. This prospective randomized study was conducted to find out the effectiveness of preoperative facial nerve diffusion tensor imaging tractography (DTI) to predict location of the nerve and preservation of facial nerve function in surgery for large vestibular schwannomas. Materials and Methods: In this prospective randomized study, we recruited 100 patients with a large vestibular schwannoma(> 3cm). After initial scrutiny, 94 patients were randomized based on a computer generated chart. In group I, preoperative DTI was done and the operating surgeon was informed about the position of facial nerve preoperatively. In group II, DTI was not done. The facial nerve preservation rates and clinical outcome at follow up was compared between the two groups. Results: Out of 94 patients, there were 47 patients in group I (DTI group) and 47 patients in group II (Non DTI group). In DTI group, 40 patients were left for comparison after the exclusion criteria was applied. Preoperative DTI predicted that the facial nerve position was concordant with its intraoperative position in 39 patients (97.5% concordance). Facial nerve preservation rates were statistically significant in group I (DTI group) (P value = 0.002). Conclusion: The study establishes the role of preoperative DTI tractography for better facial nerve preservation in surgery for large vestibular schwannomas (>3 cm).

Crescent durotomy for midline posterior fossa lesions
Manas Panigrahi, Shaikh Mohammad Samiruddin, Sudhindra Vooturi
January-February 2019, 67(1):155-158
DOI:10.4103/0028-3886.253637  PMID:30860115
Objective: The conventional midline suboccipital craniectomy, the standard approach for posterior fossa lesions, involves ligation of the occipital sinus. Postoperative sequelae that could occur from ligation of the occipital sinus include hydrocephalus, cerebrospinal fluid (CSF) leak, and pseudomeningiocoele formation. The standard of practice of venous pathway preservation, as practiced elsewhere in the cranium, should also be attempted in the posterior fossa. In the current study, we compared postsurgical complications between conventional “Y” durotomy with the proposed crescent durotomy in patients with posterior fossa lesions who underwent midline suboccipital craniectomy. Materials and Methods: The prospective data of 104 patients who underwent a midline suboccipital craniotomy for posterior fossa tumors between January 2011 and December 2015 was performed. Comparison of study variables was done between the durotomy techniques used. Results: Of the 104 patients who formed the study population, 39 (37.5%) were women. While 75 patients underwent crescent durotomy, the remaining underwent the conventional “Y” durotomy. Among the postsurgical complications, there were no differences between groups in terms of their surgical site hematoma (2.7% vs 3.4%; P = 1.000) and edema (1.3% vs 0.0%; P = 1.000). The groups were also similar in terms of the incidence of postsurgical CSF leak (1.3% vs 6.9%; P = 0.187) and cranial nerve deficits (4.0% vs 6.9%; P = 0.617). However, more number of patients who underwent the “Y” durotomy had postoperative pseudomeningiocoele (2.7% vs 17.2%; P = 0.017). Conclusion: The “crescent” durotomy is a novel dural opening technique which attempts to preserve the normal venous flow physiology. The crescent durotomy reduces the need for a duroplasty, facilitates a comfortable primary closure, thus reducing the risk of developing a postoperative pseudomeningiocoele.

January-February 2019, 67(1):118-122
DOI:10.4103/0028-3886.253586  PMID:30860108
Aims: To determine the correlation between our questionnaire scores and two standard Parkinson's disease (PD) disability scores [Unified Parkinsons' Disease Rating Scale (UPDRS) and Hoehn and Yahr (H and Y)], and to study the correlation between the various subgroups of our dysphagia screening questionnaire. Settings and Design: This study was conducted at a movement disorder clinic in a tertiary care hospital in Kochi, Kerala. This was a cross-sectional observational study. Materials and Methods: A questionnaire was developed comprising 11 items, keeping in mind the most relevant swallowing issues in PD patients. The questions were subdivided into four groups representing the different stages of swallowing. Reliability and validity studies were conducted for the questionnaire. Corresponding UPDRS and H and Y scores were documented on the same day. Statistical Analysis Used: Mean and standard deviation (SD) values of the scores in each group and the correlation between scores (Pearson correlation coefficient) were done. Results: Responses were obtained from 106 PD patients (67 males, 39 females), with a mean age of 66.9 years (SD, 8.62). Our questionnaire score showed a high coefficient of variation (145%) compared to the UPDRS and H and Y scores. There was also moderate correlation between our questionnaire score and the two standard scores with a significant P value. Finally, the highest mean scores were for questions from group A and the least for questions from group D. Conclusions: The association between worsening motor symptoms and swallowing difficulties has been documented in this study. The oral stage of swallowing remains the most affected in PD, which can be recognized early using our questionnaire.

DOI:10.4103/0028-3886.253587  PMID:30860109
Background: Visual misperceptions (VMs) and hallucinations (VHs) often go unreported in patients with Parkinson's disease (PD). We assessed the utility of single and bistable visual percepts as testing tools for visual perceptual abnormalities in PD. Aim: To assess VM in patients with PD using single and bistable percepts as testing tools. Settings and Design: This was a case-control study conducted at a movement disorders clinic. Materials and Methods: Thirty patients with PD and 30 age and sex-matched controls were assessed for motor severity and stage using Unified Parkinson's Disease Rating Scale-III (UPDRS-III) and modified Hoehn and Yahr scale. Higher mental functions were assessed by Mini-Mental State Examination (MMSE), Frontal Assessment Battery (FAB), and Trail making tests (TMT-A and B) scores. The participants were presented with monochromatic images representing either “single” or “bistable percepts” and the misperceptions were recorded. VM scores of patients and controls were compared. The correlation between disease duration, treatment period, motor severity, frontal executive functions, and VMs were determined. Results: Twenty-six patients had mild-to-moderate PD. Patients with PD had higher mean VM scores (P < 0.0005). None of the patients reported VHs. TMT-A, TMT-B, TMT-B − A scores were significantly lower in the control group (P < 0.0005). Cases showed significant positive correlation of VM with disease duration, treatment duration, UPDRS-III score, H and Y stage, and TMT A and B and an inverse correlation with MMSE and FAB scores. The patients with VM score greater than the upper limit of normal (Mean + 1.5 standard deviation [SD]), calculated from the control group, showed similar correlation of VM with motor and cognitive parameters. Conclusions: VMs are frequent in patients with PD when assessed using single and bistable visual percepts. VM correlates with frontal executive dysfunction, disease duration, and severity.

Background: Acute ischemic stroke therapy is time sensitive, and optimum treatment is missed due to pre-hospital and/or in-hospital delay. Materials and Methods: A prospective observational (before and after) study was conducted for 1 year.The study period was defined as phase-I or pre-education phase, phase-II or immediate post-education phase, and phase-III or delayed post-education phase, with each phase lasting for 4months. All consecutive stroke patients presenting within 12 hours of stroke onset were enrolled. Baseline and outcome data including acute stroke care quality matrices and functional outcomes were collected. Results: A total of 264 patients were enrolled. All acute stroke care quality matrices improved significantly (P ≤ 0.01) with a median door to imaging time (DTI) of 114, 35, and 47 minutes in the three phases consecutively. In phase-II, proportions of patients imaged within 25 minutes of arrival increased by 35%. Mean door to needle (DTN) time were 142 ± 49.7,63.7 ± 25.1, and 83.9 ± 38.1 minutes in the three consecutive phases. Patients with DTN < 60 minutes of arrival increased by 63%. Modified Rankin score (mRS) at 3 months improved significantly in all ischemic stroke patients (P = 0.04) and patients with mRS of 0–2 increased by 22%. Conclusions: Stroke education to emergency department (ED) staff is an effective method to improve acute stroke care.
