Objective: The outcomes of motor and nonmotor features of Parkinson’s disease (PD) following deep brain stimulation (DBS) vary among its subtypes. We tested whether preoperative motor subtyping using the modified tremor/postural instability and gait difficulty ratio (T/P ratio) could indicate the short-term motor, nonmotor and quality of life (QOL) outcomes of subthalamic nucleus (STN) DBS. Methods: In this prospective study, 39 consecutive STN DBS patients were assessed in the drug-OFF state before surgery and subtyped according to the T/P ratio. Patients were reassessed 6 months after surgery in the stimulation ON-drug-OFF state, and the percentage changes in motor, nonmotor and QOL scores (Parkinson’s Disease Quality of Life Questionnaire [PDQ-39]) were calculated. Results: The modified T/P ratio was moderately and positively correlated with the percentage change in the Unified Parkinson’s Disease Rating Scale III score in the OFF state, the sum of cardinal motor signs, the Non-Motor Symptom Scale score, and QOL (PDQ-39). Conclusion Preoperative PD motor subtyping can be used as an indicator of the short-term outcomes of STN DBS in PD patients.

Objective: We assessed the role of video-oculography (VOG) in confirming clinically suspected slow saccades in PSP and differentiating PSP from Parkinson’s disease (PD). We also measured the correlation of both saccadic velocity and latency in PSP patients with scores on the PSP Rating Scale, Montreal Cognitive Assessment, and frontal assessment battery. We assessed the frequency of apraxia of eyelid opening (ALO) and reflex blepharospasm in PSP and PD patients. Methods: A total of 112 PSP patients with slow saccades but not gaze palsy, 50 PD patients, and 50 healthy controls (HCs) were recruited. The Movement Disorders Society task force-PSP and PD criteria were used for the diagnoses. All the subjects underwent VOG. Results: Horizontal and vertical saccadic velocities and latencies differentiated PSP patients from PD patients and HCs (p<0.001). Vertical saccadic velocity and latency accurately differentiated PSP with predominant parkinsonism (PSP-P) patients from PD patients (p<0.001 and 0.012, respectively). A couple of vertical and horizontal saccadic velocities differentiated PSP-Richardson’s syndrome (PSP-RS) patients from PSP-P patients (vertical velocity of left eye: p=0.024; horizontal velocity of right eye: p=0.030). In vertical gaze, the mean velocity cutoff showed good sensitivity and specificity in differentiating PSP patients from HCs and PD patients. Prolonged horizontal gaze latency was associated with more severe PSP and worse global cognitive and frontal dysfunction. ALO and reflex blepharospasm were observed only in PSP patients. Conclusion VOG is useful for confirming slow saccades in PSP-RS and PSP-P patients and for differentiating PSP-P patients from PD patients. Prolonged horizontal gaze latency was associated with more severe PSP and worse cognitive dysfunction. ALO and reflex blepharospasm were observed only in PSP patients.

The purpose of this review is to identify prevalent trends and risk factors in depression,anxiety,and eating disorders in the adolescent population in the post coronavirus disease 2019(COVID-19)scenario.We examined the literature published on adolescent mental health since the COVID-19 pandemic.We chose to summarize studies published from 2019 to 2022,using bibliographic search tools.We developed criteria for selecting articles for our review using diagnostic indicators and keywords.Mental health conditions such as depression,anxiety and eating disorders are commonly prevalent in this population and have shown increasing rates in the past three years.Some risk factors associated with these diagnoses include reduction in social interaction,increased workloads,routine shifts,sleep quality,social media usage and parental involvement.Routines,sleep cycles,physical activity,and social media should all be considered as a part of prevention in this population.Approaches that seem to be successful include maintaining social ties and avoiding negative social media usage with harmful content.Increased global public awareness,as well as parental awareness,through media campaigns,is critical to slowing the spread of mental health challenges in adolescents and teenagers in the post-COVID-19 era.

Fenestrated vertebrobasilar junction aneurysms are uncommon vascular lesions. Surgical intervention remains extremely challenging due to the deep location and complex anatomy with adjacent cranial nerves and perforator vessels. Endovascular approach is safer and generally accepted as the primary treatment method. Optimal angiographic projections with three-dimensional reconstructions to guide microcatheter selection remain vital to successfully treating aneurysms with challenging fenestration anatomy. This report details the endovascular methods in two cases of fenestrated vertebrobasilar junction aneurysms with different coiling techniques.

Introduction: The world is currently experiencing the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [COVID-19], however, this is not a new phenomenon; it occurred in 2009-2010 in the form of novel influenza A. (H1N1). The H1N1 virus primarily afflicted people between the ages of 26 and 50, but SARS-CoV-2 primarily afflicted those over the age of 60, increasing the number of deaths owing to their weakened immunity. The report provides a case study of the impact of H1N1 and SARS-CoV-2 in India. Methods: Data is obtained from The Hindustan Times newspaper, GoI press releases and World Health Organization (WHO) reports. Results: The incidence rate was initially low and it was only by the 10-15th week that it started increasing. There is an initial upward trend before levelling out followed by a second wave and third wave. COVID-19 exhibited a steeper growth, where the steps taken by the Government were ineffective leading to higher death cases. Kerala was affected due to the travellers returning from the Middle East, while Maharashtra and Delhi saw large incidence rates due to the migrant influx and communal gathering. Conclusion: The most effective and practical approach is to test the symptomatic patients and aggressive testing to contain the transmission. Awareness campaigns to educate the public about social distancing and personal hygiene is more practical. There is still scope of improvement with regards to the public health care support, preparedness and response. Lockdown measures could have been avoided if the initial screening was conducted properly.
