RESUMO
OBJECTIVE: Central post-stroke pain (CPSP) refers to neuropathic pain in areas of the body corresponding to stroke lesions. Duloxetine, a serotonin-norepinephrine reuptake inhibitor, is safe and effective against neuropathic pain. In this randomized double-blind placebo-controlled study, we studied the effect of duloxetine in CPSP patients. METHODS: Consecutive patients satisfying the inclusion criteria were enrolled in the study and were randomized in a simple 1:1 randomization to duloxetine and placebo groups. Baseline demographic, clinical and imaging data were obtained. Prespecified primary outcome was comparison of change in pain intensity from baseline to 4 weeks, as assessed on Numeric Rating Scale (NRS) in both groups. Prespecified secondary outcomes were comparison of change in average pain severity from baseline to 4 weeks as measured on Short-form McGill Pain Questionnaire-2 (SFMPQ-2) score and Pain Disability Index (PDI) score and comparison of Patient Global Impression of Change (PGIC) score at the end of 4 weeks of treatment in both groups. Duloxetine at doses of 30 mg and similarly appearing placebo tablets were given and the dose was doubled if there was no response at the end of 2 weeks. Response to treatment was defined as ≥2 points reduction of NRS pain score. RESULTS: In total, 82 patients were enrolled in the study, 41 in each group. There was a significant difference in reduction in NRS score between duloxetine and placebo group from baseline (6.51 ± 1.03 vs 6.37 ± 1.41) to 4 weeks (3.02 ± 1.70 vs 4.40 ± 1.77, P = .02 for difference in reduction between groups). SFMPQ-2 score (P = .032) and Pain Disability Index score (P = .005) also differ significantly from baseline to 4 weeks between the two groups. PGIC score at the end of 4 weeks was significantly different between the two groups (5.15 ± 1.54 vs 3.89 ± 1.51; P < .001). Responder rate (defined as % of patients with ≥ 2 points reduction on NRS pain score from baseline to end of 4 weeks), on post hoc analysis was found to be significantly higher in duloxetine group (80.5%) than placebo group (43.9%) (P = .042). CONCLUSIONS: Duloxetine can be an effective treatment option for patients with moderate to severe central post-stroke pain.

BACKGROUND: The aim of the study was to investigate the clinical profile, disease burden, quality of life, and treatment patterns of various headache subtypes. METHOD: In this prospective observational study, 815 patients presenting with chief complaints of headache between January 2020 to September 2021 were registered. After a detailed history, clinical examination, and subtyping, they were assessed at baseline with well-validated scales for severity (Visual Analogue Scale-VAS), disability burden (Migraine Disability Assessment- MIDAS), Humanistic burden (Headache Impact Test-HIT-6), and quality of life (World health organization-quality of life-WHO-QoL-8) scores. After initiating adequate management, parameters were reassessed at 3 and 6 months. RESULTS: 549 (67.7%) patients had migraine (395-episodic migraine, 144-chronic migraine), 266 (32.2%) patients had tension-type headache (TTH). Loss of sleep, prolonged working hours, and stress were common triggers. Disease burden, severity, and poor life quality was quite high in migraine patients (76.5% with moderate to severe disability, 61.7% with severe headache at onset, and 72% with poor life quality). All parameters had statistically significant improvement with preventive medication and lifestyle changes. CONCLUSION: In our study, we found migraine was the most common primary headache followed by TTH. Migraine patients had more severity, disease burdens, and inferior quality of life at onset compared to other headaches. With early and proper diagnosis as well as preventive treatment (including lifestyle modifications), all parameters could be reversed positively in a brief time. This is the first study on headache burden and its effect on the quality of life in the north Indian population.
RESUMO
PURPOSE OF REVIEW: Researchers suggests that patients with COVID-19 develop neuropathic pain within weeks or months following infection and that patients with neuropathic pain and COVID-19 sometimes present with deterioration of neurologic complications and pain exacerbation. The objective of this systematic review is to discuss the case-reports having neuropathic pain during and after COVID-19 infection. RECENT FINDINGS: Case reports that has described about patients getting neuropathy or neuropathic pain around the disease either immediately or late post COVID were included. The data was extracted and qualitatively synthesised. Literature was searched and 939 articles were found. 12 articles were screened as per the eligibility criteria and finally, 6 case reports on neuropathic pain in Covid-19 were selected from the database and manual search and finalised for analysis. 2 cases of herpes zoster and post herpetic neuralgia, 2 cases of intense burning pain, 1 case of trigeminal neuralgia and 1 of brachial plexopathy included for the review. Covid 19 viral neurogenic invasion is something very newly discovered topic of discussion in the field of research. With the passage of time, more cases will emerge and more data will be available for research. The review is registered in Prospero with no. CRD42021257060.

BACKGROUND AND OBJECTIVES: BPPV (benign paroxysmal positional vertigo) is a syndrome marked by brief bouts of vertigo accompanied by rapid changes in head position. Recent ongoing therapeutic approaches used are vestibular rehabilitation exercises and physical maneuvers like the Epley maneuver, Semont maneuver. Gans repositioning maneuver (GRM) is a new hybrid maneuver, consisting of safe and comfortable series of postures that can be conveniently applied on patients with any spinal pathology or even in elderly. METHODS: Randomized controlled/clinical trials of the Gans maneuver were identified. The proportion of patients who improved as a result of each intervention was assessed, as well as the conversion of a 'positive' Dix-Hallpike test to a 'negative' Dix-Hallpike test. RESULTS: Improvement was seen in almost all patients with the Gans maneuver and the Epley Maneuver in three trials with the pooled estimate for random effect model is 1.12 [0.87; 1.43: 100%]. There were no significant side effects from the treatment. DISCUSSION: This study shows that the Gans maneuver is a safe and effective treatment for patients suffering from posterior canal BPPV. TRIAL REGISTRATION: The review is registered in Prospero with no. CRD42021234100.

Introduction; Epithelioid sarcoma is a malignant mesenchymal neoplasm with evidence of epithelial differentiation. All the cases reported in the solid organs are of "proximal type" occurring in adults. We report a primary epithelioid sarcoma arising in the adrenal gland of a young male. Case report: An 11-year-old male patient presented with right loin pain. Imaging revealed a 10.8 × 10.8 × 13.5 cm complex cystic mass with obscured right adrenal gland. Clinical and radiological studies did not reveal metastases. Histologic features were those of proximal type epithelioid sarcoma with extensive central necrosis. Immunohistochemistry showed strong positivity for pancytokeratin, vimentin, and CD34. Nuclear expression of SMARCB1 (INI-1) protein was lost. Conclusion: Proximal type of epithelioid sarcoma can arise from solid organs such as the adrenal.

The second wave of SARS-CoV-2 infection came as a hypoxic emergency and situation became worse in rural India, where undiagnosed COVID-19 patients died without any diagnosis or intervention. The primary aim of this innovative model was the early diagnosis of suspected SARS-CoV-2 cases, providing empirical treatment and timely referral to appropriate COVID care facilities. Fever was measured with infrared thermometer and oxygen saturation level with pulse oximeter. A total of 8203 people were screened, of which 274 persons were febrile and 69 (25%) were hypoxic too. Sixty-four out of 69 (93%) patients turned COVID-19 positive on reverse transcription-polymerase chain reaction. At the end of 3 weeks, 48/64 (75%) patients were successfully discharged. This model can be easily implemented in resource-limited regions to identify and prioritize the patients not only in this pandemic but also in outbreak of other communicable diseases.

BACKGROUND: There are very few studies based on the updated dystonia classification. However, a comparison of the idiopathic and non-idiopathic dystonias based on the newer classification has not been done previously. OBJECTIVES: To study and compare the clinicoetiological profile of patients with idiopathic and non-idiopathic dystonia attending a movement disorder clinic of a tertiary care teaching institution. METHODS: All the consecutive dystonia patients from October 2017 to September 2019 fulfilling the inclusion criteria were subjected to a detailed clinical evaluation. Investigations were performed as per requirement. Patients were classified according to the consensus update on phenomenology and classification of dystonia. RESULTS: A total of 183 patients with dystonia were included, with 61.7% (113) males and 38.3% (70) females. The idiopathic group revealed a significantly earlier age of onset with cases slightly outnumbering (n = 96/183, 52.5%) the non-idiopathic group (n = 87/183, 47.5%). Focal dystonias were the commonest type in both the idiopathic (n = 58/96, 60.4%) and non-idiopathic groups (n = 30/87, 34.5%), while generalized dystonia accounted for 26.4% (n = 23/87) of the non-idiopathic cases and only 3.1% (n = 3/96) of the idiopathic cases. The majority of idiopathic cases were isolated dystonia (n = 93/96, 96.9%), while all hemidystonias were non-idiopathic. CONCLUSION: Focal dystonias were the commonest in both idiopathic and non-idiopathic groups, while generalized dystonia was significantly commoner in the non-idiopathic group. Acquired causes like drugs, perinatal insult were the commonest etiology in the non-idiopathic group. Hemidystonia was found exclusively in the non-idiopathic acquired group.

With rising global concerns over the alarming levels of particulate pollution, a sustainable air quality management is the need of the hour. Air filtration research has gained momentum in recent years. However, the research perspective is still blinkered toward formulating new fiber systems for the energy-intensive electrospinning process to fabricate high quality factor air filters. A holistic approach on sustainable air filtration models is still lacking. The air filter model presented in this work uses a simple process involving water-induced self-organization and self-regeneration of nanofibers, and an easy recycling route after the filter life that not only facilitates reuse of the microfibrous scaffold holding the nanofibers but also allows renewal of nanofibers. Three generations of air filters are fabricated and tested, all having high particulate matter (PM)-adsorbing tendency, high filtration efficiency (>95%), and high Young's modulus (≈5 GPa). The renewable air filters offer a sustainable alternative to the present cost-intensive electrospun air filters.
RESUMO
BACKGROUND: Coronaviruses mainly affect the respiratory system; however, there are reports of SARS-CoV and MERS-CoV causing neurological manifestations. We aimed at discussing the various neurological manifestations of SARS-CoV-2 infection and to estimate the prevalence of each of them. METHODS: We searched the following electronic databases; PubMed, MEDLINE, Scopus, EMBASE, Google Scholar, EBSCO, Web of Science, Cochrane Library, WHO database, and ClinicalTrials.gov . Relevant MeSH terms for COVID-19 and neurological manifestations were used. Randomized controlled trials, non-randomized controlled trials, case-control studies, cohort studies, cross-sectional studies, case series, and case reports were included in the study. To estimate the overall proportion of each neurological manifestations, the study employed meta-analysis of proportions using a random-effects model. RESULTS: Pooled prevalence of each neurological manifestations are, smell disturbances (35.8%; 95% CI 21.4-50.2), taste disturbances (38.5%; 95%CI 24.0-53.0), myalgia (19.3%; 95% CI 15.1-23.6), headache (14.7%; 95% CI 10.4-18.9), dizziness (6.1%; 95% CI 3.1-9.2), and syncope (1.8%; 95% CI 0.9-4.6). Pooled prevalence of acute cerebrovascular disease was (2.3%; 95%CI 1.0-3.6), of which majority were ischaemic stroke (2.1%; 95% CI 0.9-3.3), followed by haemorrhagic stroke (0.4%; 95% CI 0.2-0.6), and cerebral venous thrombosis (0.3%; 95% CI 0.1-0.6). CONCLUSIONS: Neurological symptoms are common in SARS-CoV-2 infection, and from the large number of cases reported from all over the world daily, the prevalence of neurological features might increase again. Identifying some neurological manifestations like smell and taste disturbances can be used to screen patients with COVID-19 so that early identification and isolation is possible.

Alarming levels of particulate matter pollution in air pose a serious health threat in several countries, therefore intriguing a strong need for an economic and a viable technology of air filtration. Current air purification technology is rather expensive with certain types even having the risk of emitting hazardous by-products. The authors have developed a multifunctional air filter inspired from the nasal hairs possessing an ability to specifically trap/exhale the foreign particles and allergens while still letting the air flow. This design is achieved by introducing different functionalities at different dimensional scale employing a bottom-up approach starting with an organic molecule which is further self-organized to form nanoparticles and ultimately to a nanofibrous mesh. While the molecular building block inherently possesses the property of shielding Ultraviolet (UV) rays, the nanofibrous mesh built up from it aids in trapping the particulate matter while maintaining good air flow. By controlling the concentration of the organic molecule, the formation of fibers has been enabled in the nanoscale regime to obtain high particle-capture possibilities. The self-assembled nanofibrous filter thus designed has achieved a high filtration efficiency of ≈90% for the PM 2.5 particle in congruence with the ability to block the harmful UV radiations.

The most common cause of proximal radioulnar synostosis in adults is traumatic, usually after forearm fractures. Disabling complications are mainly loss of rotatory movements of the forearm. Various surgical procedures have been described in the literature to end up in forearm synostosis as a complication. We here presented a rare case of proximal forearm synostosis following a common but improper surgical technique for an olecranon fracture complicated by implant infection. The synostosis was treated by resection and fascia lata interposition graft.

Cerebral cavernous malformation is an angiographically occult, well-circumscribed, benign hamartoma consisting of thin-walled sinusoidal vascular channels. Intracranial mucormycosis represents one of the most severe manifestations of mucor infection. We, hereby, report a case of cavernous malformation made rarer with concomitant mucormycosis. A 22-year-old female presented with left-sided facial seizures since age of 7 years and headache for the past 3 years. Magnetic resonance imaging brain revealed a right posterior frontal lobe cavernous malformation. Right frontal craniotomy with excision of cavernoma was done. Gross examination showed a solid cystic mass with multiple mulberry protrusions. Histopathological examination revealed features of cavernous malformation with evidence of mucormycosis. A final diagnosis of cavernous malformation with mucormycosis was rendered and microbiological studies were advised. To the best of our knowledge, this is the first case report of a cerebral cavernous malformation with mucormycosis in an immunocompetent patient without any risk factor.
RESUMO
Background: Post-stroke pain is common after a stroke and might be underreported. We describe Persistent Facial Pain (PFP) developed in post-stroke patients. Method: ology: This was a prospective hospital-based cohort study of stroke patients, and patients were followed up. Out of 415 stroke patients, 26 developed PFP. Result: Out of all PFP patients, six patients had an ischemic stroke, and 20 had a hemorrhagic stroke. 57.7% of patients had hypertension, while 34.6 patients had diabetes. The stroke location was left-sided in 12 patients and right-sided in 14 patients. 46.15% of patients responded to venlafaxine, 30.77% responded to amitriptyline, and 23.08% responded to pregabalin. Conclusion: Persistent facial pain is a pain syndrome that might be missed in patients post-stroke. It might be more common in hemorrhagic stroke patients than in ischemic stroke patients. It responds adequately to antidepressants. A high index of suspicion is required to diagnose and appropriately manage these patients.
RESUMO
BACKGROUND: Aphasia is a language disorder acquired secondary to brain damage. This study aims to evaluate clinical and radiological profile of patients with post stroke aphasia and factors affecting its recovery. METHODS: We conducted a prospective study of patients with first left Middle or Anterior Cerebral Artery infarct or Intracerebral Hemorrhage (ICH) with aphasia admitted within 14 days of stroke onset. Aphasia Quotient (AQ) was assessed at 2 weeks (AQ1) and 3 months (AQ2) using Western Aphasia Battery-Hindi version. Magnetic Resonance Imaging of brain with Diffusion Tensor Imaging (DTI) of bilateral Arcuate Fasciculus (AF) and Corticospinal Tract was done at admission, and stroke volume, Laterality Indices of Fractional Anisotropy (LI-FA), Mean Diffusivity (LI-MD), Radial Diffusivity (LI-RD), Axial Diffusivity (LI-AD) and Apparent Diffusion Coefficient (LI-ADC) were obtained. RESULTS: 36 patients [8 ICH and 28 Acute Ischemic Stroke (AIS)] were included. AQ1 and AQ2 were significantly higher in subcortical stroke than cortical. AQ2 and increase in AQ scores (including its subscores) were significantly higher in ICH than AIS. National Institutes of Health Stroke Scale score at admission and volume of stroke had significant negative correlation with AQ1 and AQ2. Laterality Index of Fractional Anisotropy of Arcuate Fasciculus [LI-FA (AF)] had significant positive correlation with AQ2 and naming score at 3 months. Laterality Index of Mean Diffusivity of Arcuate Fasciculus [LI-MD (AF)] had significant negative correlation with AQ1, AQ2 and all subcomponents of AQ2. Significant positive correlation was seen between improvements in Modified Rankin Scale score and AQ. CONCLUSION: The study shows that DTI can be used to predict severity of aphasia at follow up and recovery in language and motor functions occur in parallel.
