Understanding Tourism Dynamics Using GIS and Forecasting Model in Banswara District, Rajasthan, India

Understanding the tourism dynamics of an area involves a rigorous literature review, interviewing the local people and experts, and visiting the sites. This also involves getting acquainted with the transport network of the area to know about the accessibility to the tourism destination, which ultimately helps in preparing a suitable plan for tourism development by creating tourist circuits. Forecasting tourism demand with the help of past data helps put a better picture in front of planners and administration so they can plan more efficiently. Thus, a proper understanding of tourism dynamics requires a holistic vision. The present study tried to understand the tourism dynamics of Banswara district in Rajasthan state, India, by using forecasting techniques and GIS. This twin methodology used in this study highlights the fact that Banswara tourism is at its incipient stage and that there is a substantial prospect of religious, historical, and nature-based tourism in this area. Few of the sites are well connected with the road network, and thus, by taking connectivity into account, tourist circuits are designed

Narrative review of epilepsy: getting the most out of your neuroimaging

Neuroimaging represents an important step in the evaluation of pediatric epilepsy. The crucial role of brain imaging in the diagnosis, follow-up and presurgical assessment of patients with epilepsy is noted and has to be familiar to all neuroradiologists and trainees approaching pediatric brain imaging. Morphological qualitative imaging shows the majority of cerebral lesions/alterations underlying focal epilepsy and can highlight some features which are useful in the differential diagnosis of the different types of epilepsy. Recent advances in MRI acquisitions including diffusion-weighted imaging (DWI), post-acquisition image processing techniques, and quantification of imaging data are increasing the accuracy of lesion detection during the last decades. Functional MRI (fMRI) can be really useful and helps to identify cortical eloquent areas that are essential for language, motor function, and memory, and diffusion tensor imaging (DTI) can reveal white matter tracts that are vital for these functions, thus reducing the risk of epilepsy surgery causing new morbidities. Also positron emission tomography (PET), single photon emission computed tomography (SPECT), simultaneous electroencephalogram (EEG) and fMRI, and electrical and magnetic source imaging can be used to assess the exact localization of epileptic foci and help in the design of intracranial EEG recording strategies. The main role of these “hybrid” techniques is to obtain quantitative and qualitative informations, a necessary step to evaluate and demonstrate the complex relationship between abnormal structural and functional data and to manage a “patient-tailored” surgical approach in epileptic patients

Dynamic MRI lesion evolution in paediatric MOG-Ab associated disease (MOGAD)

INTRODUCTION: Myelin oligodendrocyte glycoprotein (MOG) antibodies are associated clinically with either a monophasic or relapsing disease course in both children and adults. There are few studies studying lesion evolution in children with myelin oligodendrocyte glycoprotein antibody associated disorder (MOGAD). AIM: The aim of this study was to examine MRI lesion evolution over time in a large single-centre paediatric MOGAD cohort. METHODS: We retrospectively identified patients with MOGAD from a tertiary paediatric neurosciences centre (Great Ormond Street Hospital) between 2001 to 2022. RESULTS: A total of 363 MRI scans from 59 included patients were available for analysis. Median age at presentation was 4 yrs (IQR 4-9), 32 (54.2%) were female and 34 (57.6%) were of non-white ethnicities. Twenty-seven children (45.8%) had a monophasic illness and 32 (54.2%) had a relapsing disease course. In the relapsing MOGAD group, median number of relapses was 4 (range 2-30). Initial presentation was ADEM in 27(46%), ON in 18 (31%) ADEM-ON in 4 (7%), ADEM-TM in 6 (10%) TM in 2 (3%) ADEM-TM-ON in 1 (2%) and ON-Brainstem syndrome in 1 (2%). There was no difference in demographics or clinical presentation between monophasic and relapsing groups. Fifteen patients (25.4%) had gadolinium enhancement on initial attack MRI. Seven out of 32 (21.9%) relapsing patients had persistent enhancement on follow-up MRI scans. One patient with a clinical transverse myelitis at presentation was MRI negative. New asymptomatic lesions following first clinical event were seen in 5/27 (18.5%) monophasic patients and 8/32 (25%) relapsing patients. During follow-up interval scanning,38 out of 59 have had follow up neuroimaging after their first attack whereas15/32 had relapsed before having a follow up MRI. Complete lesion resolution was reported in 9/38 (23.6%) (8 monophasic, 1 relapsing) following 1st acute attack, 3/32 (9.3%) after 2nd acute attack, and 1/32 (3.1%) following 3rd acute attack and 0/32 following 4th acute attack. Partial resolution of MRI lesions was seen in 7/20 (35%) monophasic patients and 7/32 (21.8%) relapsing patients at follow-up scans. CONCLUSIONS: Demyelinating lesions in paediatric MOGAD are dynamic and timing of MRI scanning may influence CNS region involvement. Unlike in multiple sclerosis, a significant number of MOGAD patients will have complete lesion resolution at first follow-up, although the ability to repair is reduced following multiple relapses

Study of epidemiology, clinicopathological correlation, prognostic factors and management in squamous cell carcinoma of vulva

Background: Carcinoma of the vulva is rare cancer, pruritus is the most common and long-lasting reported symptom. It is found to be associated with HPV and HIV infection. Currently, a more individualized and less radical treatment is suggested. In this study we evaluated epidemiology, clinicopathological prognostic factors, HPV distribution and risk factors for metastases to lymph nodes. We also reviewed multidisciplinary clinical management carried out at our institute.Methods: It is a prospective study of 25 biopsy proven cases of Squamous Cell Carcinoma of Vulva, treated at our center from September 2014 to September 2016. We collected the data regarding the clinical presentation, histological details, treatment given, survival and complications. HPV 16 and 18 testing were done using PCR method. Median follow up of the patients are for 24 months.Results: The mean age of patients was 54.6 years. Commonest presentation was perineal itching (36%). HPV 16/18 were positive in 25% of the patients. Radical vulvectomy with bilateral groin dissection was done in 14/25 (56%) patients. Among these 14 patients, 35.7 % (5/14) has lymph node metastases, disease free survival was 63.6% and overall survival was 81.1% for median follow up of 24 months. About one third of the patient presented with locally advanced disease.  Six (24%) patients received only chemo radiation as a treatment.Conclusions: HPV and HIV infection increase the risk of vulvar cancer. Individualization of treatment is necessary. The use of preoperative chemoradiation in locally advanced disease might have promising results in future

Magnetic resonance imaging findings in children with Parry-Romberg syndrome and en coup de sabre

BACKGROUND: The aim of this study was to: (i) describe the abnormalities seen on brain imaging in a group of children with en coup de sabre (EDCS) with/without Parry-Romberg syndrome (PRS); and (ii) identify clinical predictors of brain imaging abnormalities. METHODS: This was a single centre (Great Ormond Street Hospital, London) retrospective case series of patients with ECDS/PRS seen from 2000 to 2018. We identified patients with cutaneous manifestations consistent with the clinical descriptions of ECDS/PRS. Presenting clinical, laboratory, and radiological brain findings are described. Results are expressed as medians and ranges or frequencies and percentages. Fisher's exact test was used to identify clinical associations with magnetic resonance imaging (MRI) abnormalities. RESULTS: Fourteen patients were studied: 6 males and 8 females; median age 14 years (range 3-20). We observed neuroimaging abnormalities in 2/6 ECDS and 5/8 ECDS/PRS patients. White matter signal abnormality, dystrophic calcification, leptomeningeal enhancement, and sulcal crowding were the typical findings on brain imaging. A total of 50% of patients had no MRI abnormality despite some of these patients having neurological symptoms. The presence of seizures was significantly associated with ipsilateral enhanced white matter signalling on MRI (p < 0.05). CONCLUSIONS: In summary, we observed several distinct radiographic patterns associated with ECDS/PRS. Seizure disorder was strongly associated with the presence of ipsilateral enhanced white matter signalling. Improved neuroimaging techniques that combine morphological with functional imaging may improve the detection rate of brain involvement in children with ECDS/PRS in the future
