RESUMEN
INTRODUCTION: The effects of COVID-19 infection persist beyond the active phase. Comprehensive description and analysis of the post COVID sequelae in various population groups are critical to minimise the long-term morbidity and mortality associated with COVID-19. This analysis was conducted with an objective to estimate the frequency of post COVID sequelae and subsequently, design a framework for holistic management of post COVID morbidities. METHODS: Follow-up data collected as part of a registry-based observational study in 31 hospitals across India since September 2020-October 2022 were used for analysis. All consenting hospitalised patients with COVID-19 are telephonically followed up for up to 1 year post-discharge, using a prestructured form focused on symptom reporting. RESULTS: Dyspnoea, fatigue and mental health issues were reported among 18.6%, 10.5% and 9.3% of the 8042 participants at first follow-up of 30-60 days post-discharge, respectively, which reduced to 11.9%, 6.6% and 9%, respectively, at 1-year follow-up in 2192 participants. Patients who died within 90 days post-discharge were significantly older (adjusted OR (aOR): 1.02, 95% CI: 1.01, 1.03), with at least one comorbidity (aOR: 1.76, 95% CI: 1.31, 2.35), and a higher proportion had required intensive care unit admission during the initial hospitalisation due to COVID-19 (aOR: 1.49, 95% CI: 1.08, 2.06) and were discharged at WHO ordinal scale 6-7 (aOR: 49.13 95% CI: 25.43, 94.92). Anti-SARS-CoV-2 vaccination (at least one dose) was protective against such post-discharge mortality (aOR: 0.19, 95% CI: 0.01, 0.03). CONCLUSION: Hospitalised patients with COVID-19 experience a variety of long-term sequelae after discharge from hospitals which persists although in reduced proportions until 12 months post-discharge. Developing a holistic management framework with engagement of care outreach workers as well as teleconsultation is a way forward in effective management of post COVID morbidities as well as reducing mortality.

Introduction The way pancreatoduodenectomy (PD) is performed can vary a lot around the world, and there is no agreed-upon standard approach. To learn more about how PD is practised in India, a survey was conducted among Indian surgeons to gather information about their current practices. Methods A survey was created and shared with surgeons in India who practice pancreatic surgery. It had 33 questions that aimed to capture information about different aspects of PD practice. These questions covered topics such as the surgeons' education and experience, how they evaluated patients before surgery, what they considered during the operation, and how they managed patients after surgery. Results A total of 129 surgeons were sent the survey, and 110 of them completed it. The results showed that 40.9% of the surgeons had less than five years of experience, and 36.4% of them performed more than 15 PDs in a year. When deciding whether to perform preoperative biliary drainage, 60% of surgeons based their decision on the level of bilirubin in the patient's blood, while the rest considered other specific indications. The majority of surgeons (72.7%) looked at the trend of albumin levels to assess the patient's nutritional status before surgery. Venous infiltration was seen as a reason for neoadjuvant therapy by 76.4% of the participants, whereas 95.5% considered upfront surgery in cases of venous abutment. When it came to the type of PD, 40% preferred classical PD, 40.9% preferred pylorus-resecting PD (PRPD), and the rest chose pylorus-preserving PD (PPPD). Pancreatojejunostomy (PJ) was the preferred method for 77.3% of surgeons, while 6.3% preferred pancreatogastrostomy (PG). About 65.5% of surgeons used octreotide selectively during the operation when the duct diameter was small. Nearly all surgeons (94.5%) preferred to secure feeding access during PD, and all of them placed intraperitoneal drains. As for postoperative care, 37.3% of surgeons attempted early oral feeding within 48 hours, while 28.2% preferred to wait at least 48 hours before initiating oral feeds. Conclusions The survey revealed significant differences in how PD is practised among surgeons in India, highlighting the heterogeneity in their approaches and preferences.
RESUMEN
BACKGROUND: Multiple trials have compared reconstruction techniques used following the resection of distal rectal cancers, including straight colorectal anastomosis (SCA), colonic J pouch (CJP), side-to-end anastomosis (SEA), and transverse coloplasty (TCP). The latest meta-analysis on the subject concluded that all the reservoir techniques produce equally good surgical and functional outcomes compared with SCA. Numerous trials have been published in this regard subsequently. Hence, a network analysis (NMA) was performed to rank these techniques. METHODS: A literature search of MEDLINE, Embase, and the Cochrane Library from their inception until April 2021 was conducted to identify randomized trials. Functional and surgical outcome data were pooled. ORs and standardized mean differences (MDs) were used as pooled effect size measures. A frequentist NMA model was used. RESULTS: Thirty-two trials met the eligibility criteria comprising 3072 patients. CJP showed better functional outcomes, such as low stool frequency and better incontinence score, both in the short term (stool frequency, MD -2.06, P < 0.001; incontinence, MD -1.17, P = 0.007) and intermediate term (stool frequency, MD -0.81, P = 0.021; incontinence MD -0.56, P = 0.083). Patients with an SEA (long-term OR 4.37; P = 0.030) or TCP (long-term OR 5.79; P < 0.001) used more antidiarrheal medications constantly. The urgency and sensation of incomplete evacuation favoured CJP in the short term. TCP was associated with a higher risk of anastomotic leakage (OR 12.85; P < 0.001) and stricture (OR 3.21; P = 0.012). CONCLUSION: Because of its better functional outcomes, CJP should be the reconstruction technique of choice. TCP showed increased anastomotic leak and stricture rates, warranting judicious use.

Background: In approximately 25% of peripheral neuropathy cases, diagnosis remains obscure. In India, leprosy continues to remain one of the most frequent causes of peripheral neuropathy. We, in this prospective evaluation, performed nerve biopsies in patients with peripheral neuropathy for early confirmation of the diagnosis. Materials and Methods: A total of 55 consecutive cases of peripheral neuropathy were included in this study. All patients were subjected to clinical and electrophysiological evaluation. Sural nerve biopsies were performed in all the patients. Result: After a nerve biopsy in 29 cases, we were able to identify the underlying cause of peripheral neuropathy. In 26 cases, the diagnosis remained obscure. The most frequent histopathological diagnosis was leprosy, which was seen in 20 cases. Other diagnoses were chronic demyelinating neuropathy (four cases), vasculitis (two cases), and amyloidosis in one case. In two biopsies, the findings were consistent with hereditary neuropathies. The demonstration of lepra bacilli was the most distinctive feature. In addition, foamy macrophages (100%) and granuloma (100%) formation, epineurial (83.3%) and endoneurial infiltration (69%) along with epineurial (87.5%) and perineurial thickening (77.3%) were also noted more frequently in leprosy-associated neuropathy. Conclusion: The nerve biopsies revealed that leprosy was the most common etiology in patients with peripheral neuropathy. In approximately 47% of the cases, even nerve biopsies failed to establish a confirmed diagnosis.
RESUMEN
Primitive neuroectodermal tumor (PNET) of the orbit is a very rare entity. We report a case of a 10-year-old boy having progressive protrusion of the eyeball, restricted ocular motility, ptosis, and ocular pain for 2 months. On examination, a fixed, nontender, firm, hyperemic, nonpulsatile globular mass was palpated in the superomedial quadrant of the orbit. Computed tomography scans of the orbit depicted a well-defined, soft tissue density lesion within the orbit without evidence of any bone defect or erosion. Surgical resection of the encapsulated lesion through anterior orbitotomy followed by histopathology and immunohistochemistry examination confirmed the diagnoses of PNET. The patient has been on regular follow-up for 2 years and has shown no sign of recurrence.
RESUMEN
The connection between gastrointestinal microbiota and the brain has been described in ancient medical texts and is now well established by research. It is a bidirectional communication which plays a critical role in regulating not only the gastrointestinal homeostasis but has also been linked to higher emotional and cognitive functions. Recent studies have sought to expand on this concept by providing concrete evidence of the influence of gut microbiome on a wide array of diseases and disorders of the central nervous system. This article reviews the most recent literature published on this subject, over the previous decade and aims to establish the role of a healthy gut microbiome and probiotics as an effective adjunct in health and management of diseases of the nervous system. A literature search on PubMed database was conducted using keywords including "gut brain-axis," "gut dysbiosis," "neuropsychiatric disorders," "neurodegenerative disorders," "probiotic," and "traumatic brain injury." The search was performed without any publication date restrictions. Both animal and human studies evaluating the role of gut dysbiosis on various neurological and neurosurgical diseases, published in peer-reviewed journals, were reviewed. Current studies do not provide conclusive evidence of a direct origin of CNS disorders from gut dysbiosis, but a possible modulatory role of gut microbiota in certain neurological disorders has been implicated. An understanding of this connection can aid in finding novel therapeutic strategies for the management of neurological disorders associated with memory dysfunctions and brain and spinal cord injuries.

We analyzed the data of 102 confirmed patients with novel Coronavirus 2 infection (COVID-19) during the early period of nationwide lockdown announced in India after the declaration of pandemic. We analyzed epidemiological, clinical characteristics and outcome of hospitalization in 102 patients with positive results for novel corona virus (SARS-CoV-2) RNA testing which were traced on the basis of history of travel, contact with a confirmed COVID-19 case, resident of hotspot areas or presence of symptoms, thus providing an accurate estimate of the proportion of asymptomatic cases in the initial population. Of 102 patients enrolled in the study, 83.3% (85/102) were asymptomatic and 16.67% (17/102) were symptomatic. Seventy-seven (75.49%) were males and 24.50% (25/102) were females. Eighteen (17.6%) patients had associated comorbidities, the most prevalent of which were diabetes mellitus 10.8% (11/102), hypertension 7.8% (8/102), chronic obstructive pulmonary disease (COPD) in 3.92% (4/102), chronic kidney Disease (CKD) 0.98% (1/102), coronary artery Disease (CAD) 0.98% (1/102) and cerebro-vascular disease (CVD) 0.98% (1/102). The clinical spectrum among symptomatic COVID-19 patients varied from dry cough and fever to respiratory failure and multi-organ failure. Twelve (11.76%) patients were kept in intensive care unit (ICU). Ninety-nine (97.05%) patients recovered while three (2.94%) died during hospital stay. With majority of COVID-19 cases in India being asymptomatic, changes in biochemical and inflammatory profile were small and insignificant in asymptomatic patients when compared to symptomatic patients. Elevated NLR, lymphopenia, age and presence of comorbidities were associated with increased severity and poor outcome.

PURPOSE: The present study was undertaken to investigate epidemiological distribution, clinical manifestation, co morbid status, treatment strategy and case fatality index of emerging COVID-19 infection at SMS Medical College Hospital, Jaipur, Rajasthan. It also evaluated efficacy of hydroxychloroquine (HCQ) in treatment of patients and risk of serious adverse outcomes in patients with COVID-19 in relation to their co morbid status. MATERIALS AND METHODS: In an attempt to provide extensive information pertaining to epidemiological and clinical characteristics of COVID-19, the present study was undertaken on 522 patients. The patients were COVID-19 confirmed positive by genomic analysis through Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) at SMS Medical College and Attached Hospitals, Jaipur. The indoor admitted patient's information inclusive of demographic profile (age, sex, nationality, residence), date of confirmation for positive COVID-19 case, travel/ exposure history, date of recovery/ death, clinical features, co morbidities and treatment plan was recorded. A serial follow-up of recovered patients to evaluate infective period of the disease was also part of the study. RESULTS: A total of 522 patients of laboratory confirmed COVID-19 test by RT-PCR at SMS Hospitals, Jaipur were assessed. Among the confirmed cases, most of patients were young adult in the age group with mean age of 35.42 years. 22.41% patients were below 20 years of age, majority of patients (58.80%) were in the age range of 21 to 50 years and only 18.79% patient population was in the age range of above 50 years. Females (39.08%) were affected less than males (60.91%) with an average sex ratio of female: male being 0.64. Out of the total analyzed patients, only 24.32% patients were symptomatic, among them fever (55.90%), cough (52.75%), sore throat (49.60%) and shortness of breath (46.45%) were the most common presenting clinical manifestations while a few patients also had symptoms of headache (26.77%), chest pain (6.29%) and other symptoms (7.87%) like pain abdomen, fatigue, joints pain, altered sensorium etc. Most of symptomatic patients belonging to older age group. An average of 40.40% patient population of above 50 years of age, were symptomatic while none of the patients below 10 years of age were symptomatic. 13.98% patients had some or the other underlying co morbid disease. The most prevalent co morbidity was hypertension (42.46%) followed by Diabetes mellitus (39.72%), Old k-chest (20.54%), COPD/ Bronchial Asthma (16.43%), Coronary artery disease (13.69%), Chronic kidney disease (13.69%) and Valvular heart disease (6.84%) distributed in co morbid patients of COVID-19. 60.27% of patient population with underlying co morbid conditions were more prone to develop symptomatology complex as compared to that observed in patients with no co morbidity (18.42%). 116 patients had recovered with effective treatment till the date of data analysis. Time of recovery was counted from the date of positive report to 1st negative report of oropharyngeal sample by RT-PCR for COVID-19 with an average recovery time of 8.15 days. 23.27% patients recovered within 5 days, while 52.58% patients took about 6-10 days, 23.27% patients took 11-15 days and remaining 0.86% took more than 16 days to recover. In the present study 15 patients had died till analysis of data, among the deceased, 73.33% were above 50 year of age with a male preponderance (66.6%). Interestingly, all deceased (100%) had presented with clinical manifestations of COVID-19 and all had underlying multiple co morbid conditions. Majority of patients had early mortality after admission to hospital with two third death account in initial three days. Asymptomatic patients (cases) treated with HCQ recovered early (average recovery time =5.4 days) compared to asymptomatic patients who did not receive any treatment (control group) and had longer recovery time (average recovery time =7.6 days). CONCLUSION: The varied spectra of COVID-19 mostly affects young adult age group (third to fifth decades of life). Interestingly, early age group was also affected in significant proportion when compared with similar data from other countries. It was observed that male population seemed to be was more prone to getting infected. Majority of COVID-19 positive patients (nearly three-fourth) were asymptomatic (mostly in young age range) at the time of diagnosis, which poses a major challenge for health care workers. Fever, cough, sore throat and shortness of breath were major symptoms that could be detected in such COVID-19 patients. Symptomatic clinical manifestations were more common in old age population. Infectivity was higher in patients that had underlying co morbid disease, especially in patients with multiple co morbid conditions. Symptomatic presentation of COVID-19 was observed to be higher in patients with co morbid disease. Average recovery time from COVID-19 was 8 days with effective treatment. Mortality in COVID-19 was higher in old age population, male gender, symptomatic and co morbid patients as compared to other similarly matched group. Most of mortality was noted within first few days of admission, suggestive of early mortality due to the primary disease process. Treatment with HCQ had early recovery without effectively influencing the overall mortality.

INTRODUCTION: The resurgence of epidemic of Influenza A (H1N1) pdm 09 was phenomenal in 2015 and has become an annual phenomenon. Antigenic drift and reassortment is the rule rather than exception, conferring survival benefit to the virus. As this disease has high mortality, we compared the clinico-epidemiological profile of patients expired in the year 2015 due to "A/California/7/2009" strain with those of expired in the year 2018 due to "A/Michigan/45/2015" strain. MATERIAL AND METHOD: We collected data of all expired patients in our institute in the year 2015 from 1st January to 30th may as well as 2018 in the same time period. The data of 116 patients who expired in 2015 due to "A/California/7/2009" H1N1 strain were compared with similar data of 30 patients expired in 2018 due to "A/Michigan/45/2015" strain of H1N1. Patients of pneumonia, having age >18 years, positive for H1N1by real-time reverse-transcriptase-polymerase- chain-reaction (RT-PCR) and died in our hospital were included in this study. Clinical features and laboratory data were obtained from the hospital records of the patients. Data analysis was done using SPSS software. RESULT: In 2015 total number of hospitalized patients due to "A/California/7/2009" strain were 571 and 116(20.31%) out of them died, in 2018 those due to "A/Michigan/45/2015" total admission were 177 and 30(16.94%) out of them died (p-0.032). Though it was not statistically significant but it is lesser than in 2015 despite the fact that more patients with co morbidities were affected in 2018. Duration in ICU was significantly longer in 2018(MS) group [5(1-7)] compared to 2015 (CS) group [3(1-17)] with p value of 0.017 (i.e. < 0.05). But both groups were not different in terms of duration on mechanical ventilator. (p-0.257).The 2015 (CS) group had 74.1% with other co-morbidities versus 96.7% of those in 2018 (MS) group (p- 0.015). This implies that the mortality with "A/Michigan/45/2015" infection was mainly seen in the patients who already had one or more co-morbidities unlike "A/California/7/2009" infection.The 2018 (MS) group had significantly higher proportion (60%) of patients with acute kidney injury compared to 34.5% in 2015(CS) (p-0.019). 50% of dead patients in 2018(MS) had anemia compared to 11.2% in 2015(CS) (p<0.001). Deranged liver function test was seen in 46.7% patients in 2018(MS) compared to only 15.5% patients in 2014(CS) (p<0.001).The only reverse trend was shown in case of diabetes, A/California/7/2009 strain affected 27% diabetics compared with 6.7% affected by A/Michigan/45/2015 strain (p=0.030) (Table 5). CONCLUSION: The study showed that though "A/Michigan/45/2015" affected higher number of patients with co morbidities compared to "A/California/7/2009" but had slightly lesser mortality.

We quantified the effects on anatomical cadaver dissection of a balloon-inflation tumor model positioned in the parasellar region and approached through an orbitozygomatic (OZ) craniotomy. A modified supraorbital OZ was performed bilaterally on 5 silicon-injected cadaver heads. Ten predetermined anatomical points assigned using a frameless stereotactic device were used to measure the working area of exposure, degree of surgical freedom, and horizontal and vertical angles of attack to specific target points before and after inflation of a balloon catheter mimicking a parasellar tumor. Balloon inflation displaced the central anatomical structures (pituitary stalk, lamina terminalis, anterior chiasm, and internal carotid artery [ICA]-posterior communicating artery and ICA-A1 junctions) by 14-51% (pâ¯≤â¯.05). With tumor simulation, the vertical angle of attack increased by 67% (pâ¯<â¯.01), while the area of exposure increased by 83% (pâ¯<â¯.01) and surgical freedom increased by 58% (pâ¯<â¯.01). This tumor model also significantly displaced central anatomical sella-associated structures. Compared to a normal anatomical configuration, the tumor simulation (balloon) opened surgical corridors (especially vertical) and acted as a natural retractor, widening the angle of access to the infundibular apex-hypothalamic junction. Although this model cannot exactly mimic a tumor mass in a patient, the effects of tumor compression and sequential displacement of important structures can be combined into and then assessed in a cadaveric neurosurgical anatomical scenario for training and research.

Intraoperative adenosine is used to induce asystole to facilitate clip ligation of intracranial aneurysms. Typically, 5-10 mg doses are used per administration and approximately 30 mg is used for a given case. An obvious concern with using adenosine is that the patient can remain in asystole or that prolonged hypotension can result in cerebral or cardiovascular ischemia. The upper limit of adenosine administration remains unclear. We present a case of a patient with a large anterior communicating artery aneurysm requiring large doses of adenosine, far exceeding previously reported cases. The patient received a 90 mg dose of adenosine to achieve 5 s of asystole as well as 30 s of hypotension that facilitated vessel dissection and clip application. Moreover, in order to successfully clip his aneurysm, he received a total of 744 mg of adenosine. After each administration of adenosine, his heart rate and blood pressure returned to baseline without the need for chest compressions or other interventions. He tolerated the procedure and had a good neurological outcome. This case is the first report of using such a high dose of adenosine in intracranial aneurysm surgery and suggests that more aggressive administration of adenosine during aneurysm clipping is feasible. Transient hypotension, as seen in this report, can provide surgeons the crucial moments they need to safely secure an aneurysm from circulation.
RESUMEN
Progressive Disseminated Histoplasmosis (PDH) is mainly described in immuno-compromised individuals and rare in immuno-competent subjects. Here we report a case of progressive disseminated histoplasmosis with Comb's positive hemolytic anemia, which is infrequently reported from a country like India where histoplasmosis is not an endemic mycosis.

The purpose of the study is to examine the effect of subliminal priming in terms of the perception of images influenced by words with positive, negative, and neutral emotional content, through electroencephalograms (EEGs). Participants were instructed to rate how much they like the stimuli images, on a 7-point Likert scale, after being subliminally exposed to masked lexical prime words that exhibit positive, negative, and neutral connotations with respect to the images. Simultaneously, the EEGs were recorded. Statistical tests such as repeated measures ANOVAs and two-tailed paired-samples t-tests were performed to measure significant differences in the likability ratings among the three prime affect types; the results showed a strong shift in the likeness judgment for the images in the positively primed condition compared to the other two. The acquired EEGs were examined to assess the difference in brain activity associated with the three different conditions. The consistent results obtained confirmed the overall priming effect on participants' explicit ratings. In addition, machine learning algorithms such as support vector machines (SVMs), and AdaBoost classifiers were applied to infer the prime affect type from the ERPs. The highest classification rates of 95.0% and 70.0% obtained respectively for average-trial binary classifier and average-trial multi-class further emphasize that the ERPs encode information about the different kinds of primes.

OBJECTIVES: To describe the clinical and epidemiological factors of influenza A (H1N1)pdm09-infected patients who were pregnant or in the puerperal period during a recent influenza outbreak in Rajasthan, India. METHODS: A retrospective, observational study was performed using hospital records of individuals with confirmed influenza A (H1N1)pdm09 infection admitted to a large tertiary care center in Rajasthan, India, between January 1 and March 15, 2015. RESULTS: The study cohort included 44 patients who were pregnant or in the puerperal period. The mean age was significantly lower in the study cohort than in other female patients treated for influenza A (H1N1)pdm09 infection at the hospital during the study period (25.45±3.45years vs 40.46±13.99 years; P<0.001). Mortality was significantly higher in the study cohort than in the comparison female patients (36% vs 17%; P=0.003). Factors found to be associated with mortality were delayed initiation of oseltamivir, poor oxygen saturation at admission, and more than 50% lung involvement under radiographic examination. None of the patients in the study cohort had received a vaccination against seasonal influenza. CONCLUSION: Influenza A (H1N1)pdm09 infection during pregnancy causes more severe illness. Early recognition and timely administration of antiviral therapy can improve outcomes. The role of influenza vaccination in this high-risk population cannot be overemphasized.

BACKGROUND: Vertebrobasilar insufficiency resulting from embolism, atherosclerosis, or arterial dissection has long been a challenge for successful management and outcomes. The main treatment options include medical therapy, angioplasty and stenting, and surgical revascularization. Unlike cardiac or peripheral vascular revascularization, large randomized trials with cerebrorevascularization have not revealed favorable outcomes. In patients who have failed maximal medical therapy, and having persistent debilitating symptomology, cerebral revascularization may still be a viable option. METHODS: We report 3 patients who presented with symptoms of vertebrobasilar ischemia. The diagnosis was verified by computerized tomographic arteriography and digital subtraction angiography. RESULTS: These patients subsequently underwent revascularization with a radial artery graft. We also present a comprehensive review of the literature of treatment for vertebrobasilar insufficiency. CONCLUSIONS: Surgical revascularization should be considered in the posterior circulation in the rare subset of patients with VBI, who remain symptomatic despite having a protracted course of maximal medical therapy with large- and medium-sized vessel occlusions and poor collateral circulation.

Aneurysmal subarachnoid hemorrhage (SAH) remains an important health issue in the United States. Despite recent improvements in the diagnosis and treatment of cerebral aneurysms, the mortality rate following aneurysm rupture. In those patients who survive, up to 50% are left severely disabled. The goal of preventing the hemorrhage or re-hemorrhage can only be achieved by successfully excluding the aneurysm from the circulation. This article is a comprehensive review by contemporary vascular neurosurgeons and interventional neuroradiolgists on the modern management of cerebral aneurysms.

AIM: This in vitro study was carried out to compare the effect of LED light curing system on polymerization and hardness of silorane-based and methacrylate-based posterior composite resin. MATERIALS AND METHODS: A total of 40 samples, 20 of silorane-based composite Filtek P-90 and 20 of methacrylate-based composite Heliomolar HB measuring 2 mm thickness and 8 mm diameter were prepared using Teflon molds and cured using LED curing light. The samples were polished and tested in Knoop hardness tester using a 50-gram load and dwell time of 15 seconds on top and bottom surfaces. The percentage depth of cure was calculated, and statistical analysis was performed using two-way ANOVA test and Student t- test. RESULTS: Higher statistically significant values were seen for both the top and bottom surface hardness in silorane-based resins than methacrylate-based resins on LED light curing. CONCLUSION: Greater depth of cure was achieved in silorane-based posterior composite than in methacrylate-based posterior composite resins with a statistically significant difference.
