Hyperkinetic and Hypokinetic Movement Disorders in SSPE: A Systematic Review of Case Reports and Case Series.

Background: Subacute Sclerosing Panencephalitis (SSPE) typically presents with periodic myoclonus; however, a spectrum of movement disorders including dystonia, chorea, tremor, and parkinsonism have also been described. This review aims to evaluate the array of movement disorders in SSPE, correlating them with neuroimaging findings, disease stages, and patient outcomes. Methods: A comprehensive review of published case reports and case series was conducted on patients with SSPE exhibiting movement disorders other than periodic myoclonus. PRISMA guidelines were followed, and the protocol was registered with PROSPERO (2023 CRD42023434650). A comprehensive search of multiple databases yielded 37 reports detailing 39 patients. Dyken's criteria were used for SSPE diagnosis, and the International Movement Disorders Society definitions were applied to categorize movement disorders. Results: The majority of patients were male, with an average age of 13.8 years. Approximately, 80% lacked a reliable vaccination history, and 39% had prior measles infections. Dystonia was the most common movement disorder (49%), followed by parkinsonism and choreoathetosis. Rapid disease progression was noted in 64% of cases, with a disease duration of ≤6 months in 72%. Neuroimaging showed T2/FLAIR MR hyperintensities, primarily periventricular, with 26% affecting the basal ganglia/thalamus. Brain biopsies revealed inflammatory and neurodegenerative changes. Over half of the patients (56%) reached an akinetic mute state or died. Conclusion: SSPE is associated with diverse movement disorders, predominantly hyperkinetic. The prevalence of dystonia suggests basal ganglia dysfunction.

Insights Into Colorectal Carcinoma: A Comprehensive Review of MicroRNA Expression Patterns.

Colorectal carcinoma (CRC) remains a significant contributor to cancer-related morbidity and mortality worldwide. MicroRNAs (miRNAs) have emerged as crucial regulators of gene expression and play critical roles in various biological processes, including carcinogenesis. This comprehensive review aims to elucidate the role of miRNAs in CRC by analyzing their expression patterns and functional implications. An extensive literature review identified dysregulated miRNAs associated with different stages of CRC progression, from initiation to metastasis. These miRNAs modulate key signaling pathways in tumor growth, invasion, and metastasis. Furthermore, we discuss the potential of miRNAs as diagnostic biomarkers and therapeutic targets in CRC management. Future research directions include elucidating the functional significance of dysregulated miRNAs using advanced experimental models and computational approaches and exploring the therapeutic potential of miRNA-based interventions in personalized treatment strategies for CRC patients. Collaboration among researchers, clinicians, and industry partners will be essential to translate these findings into clinically impactful interventions that improve patient outcomes in CRC.

Neuroimaging Abnormalities in Patients with Subacute Sclerosing Panencephalitis : Prospective Follow-up Study.

OBJECTIVE: This study aimed to assess the neuroimaging abnormalities and their progression in patients with Subacute sclerosing panencephalitis (SSPE) and identify clinical predictors of these imaging findings. METHODS: This prospective observational study evaluated clinical and neuroimaging features in patients with SSPE. Patients were categorized using Dyken's criteria, Jabbour's staging system, and the definition of fulminant SSPE. They underwent comprehensive clinical assessments, cerebrospinal fluid examination, Electroencephalogram (EEG), and Magnetic Resonance Imaging (MRI) scans. Treatment involved intrathecal interferon­α and antiepileptic medications. Functional disability was assessed using the modified Barthel index. Follow-ups were performed at 6 months, including reassessment of Modified Barthel Index (MBI) and Jabbour's staging and EEG and MRI scans. RESULTS: The mean age was 13.9 ± 6.7 years, with males comprising 81.5% (44/54) of the cohort. Fulminant SSPE was noted in 33% (18/54) of cases. Disease duration before presentation varied significantly between fulminant and non-fulminant forms (p = 0.001). Neuroimaging abnormalities were more prevalent in JS III stage patients, with diffuse cerebral atrophy being a significant finding (p = 0.011). Basal ganglia involvement correlated with movement disorders. The 6­month follow-up showed increased cerebral atrophy (p = 0.004). Increasing disease duration was an independent predictor of cerebral atrophy. An Intercomplex interval (ICI) of more than 10 minutes correlated with normal neuroimaging, 10 patients died within the study period, 8 of whom had fulminant SSPE. CONCLUSION: Parieto-occipital White matter hyperintensity (WMH) is the most prevalent and sensitive neuroimaging finding for the diagnosis of SSPE. Despite interferon treatment, cerebral atrophy progressed in both aggressive and fulminant SSPE. Increasing disease duration is an independent predictor of cerebral atrophy.

Clinical features, pathogenesis, pathology, neuroimaging, clinical course and outcome of measles inclusion-body encephalitis: a systematic review of published case reports and case series.

Measles inclusion-body encephalitis (MIBE) is rare, with insights largely from case studies. We systematically analyzed subacute Sclerosing Panencephalitis (SSPE) cases in immunocompromised patients, identifying distinctive clinical and neuroimaging features. These findings could facilitate MIBE diagnosis without the need for brain biopsies. Our systematic review on MIBE and HIV-related SSPE adhered to PRISMA guidelines and was registered with PROSPERO. We searched multiple databases and followed a detailed inclusion process with independent reviews and quality assessment. Data on patient demographics, clinical features, and outcomes were compiled. A review of 39 studies on 49 MIBE patients and 8 reports on HIV-positive SSPE patients was conducted. Acute lymphoblastic leukemia, HIV, organ transplants, and malignancies were common precursors to MIBE. Perinatal HIV was prevalent among SSPE cases. Seizures were the primary symptom in MIBE, often drug-resistant and progressing to status epilepticus or epilepsia partialis continua, whereas periodic myoclonus was universal in SSPE. Neuroimaging showed distinct patterns for each group, and histopathology confirmed measles virus presence in 39% of MIBE cases. MIBE patients typically progressed to coma and death. In conclusion, MIBE and SSPE in HIV-infected patients present with distinct clinical pictures but identical brain pathological abnormalities.

The spectrum of psychiatric manifestations in subacute sclerosing panencephalitis: A systematic review of published case reports and case series.

Data related to psychiatric manifestations in subacute sclerosing panencephalitis (SSPE) is currently available only in the form of isolated case reports. In this systematic review, we evaluated the spectrum of psychiatric manifestations and their impact on the course and outcome of SSPE. Data were obtained from 4 databases (PubMed, Embase, Scopus, and Google Scholar), with the most recent search conducted on March 27, 2023. The PRISMA guidelines were followed, and the PROSPERO registration number for the protocol is CRD42023408227. SSPE was diagnosed using Dyken's criteria. Extracted data were recorded in an Excel spreadsheet. To evaluate the quality of the data, the Joanna Briggs Institute Critical Appraisal tool was employed. Our search resulted in 30 published reports of 32 patients. The mean age was 17.9 years. Schizophrenia, catatonia, and poorly characterized psychotic illnesses were the 3 most common psychiatric presentations that were seen in 63% (20/32) of cases. Catatonia was seen in 4 patients. Affective disorders, mania, and depression were reported among 22% (7/32) cases. In approximately 81% (26/32) cases, the course of SSPE was acute fulminant. Treatment with antipsychotic drugs had poor or no response. Out of 17 patients, who received antipsychotic drugs, 6 patients noted severe extrapyramidal adverse effects. SSPE often masquerades as a psychiatric disorder. Unresponsive psychiatric symptoms, early extrapyramidal signs, and progressive encephalopathy indicate SSPE.

Occurrence and determinants of seizures and their impact on tuberculous meningitis: a prospective evaluation.

OBJECTIVE: To assess the incidence of seizures and the factors contributing to poor outcomes in patients with tuberculous meningitis (TBM). METHODS: In this prospective observational study, 129 patients with TBM were enrolled at the Department of Neurology, King George's Medical University, Uttar Pradesh, India, from April 2021 to April 2023. Detailed clinical history, neurological examinations, baseline laboratory tests, contrast-enhanced Magnetic resonance imaging (MRI) and electroencephalography (EEG) were obtained for all patients. Patients received anti-tuberculous therapy and, if necessary, anti-epileptic treatment. Patients were followed for 6 months, with outcomes evaluated using the Modified Rankin Scale (MRS). RESULTS: Of the 129 patients, 48 (37.2%) reported seizures. Advanced TBM stage (p = 0.040, OR = 2.50 95% CI:1.02-6.07), cortical involvement (p = .0.013, OR = 2.58 95% CI:1.20-5.51) and spike-wave discharges in the EEG (p = 0.001) were significantly associated with seizure occurrence. After multivariate analysis, only cortical involvement (p = 0.031, OR = 2.34, 95% CI:1.08-5.08) emerged as independent predictor of for seizures. Focal to bilateral seizures (p = 0.008, OR = 9.41, 95% CI: 1.76-74.04), status epilepticus (p = 0.002, OR = 8.00, 95% CI: 1.86-34.32), and rifampicin resistance (p = 0.022, OR = 9.25, 95% CI: 1.43-59.50) were significantly associated with poor outcomes at the 6-month mark. CONCLUSION: Seizures were significantly associated with advanced stage of the disease, cortical involvement on neuro-imaging and epileptiform pattern on EEG. Additionally, focal to bilateral seizures and status epilepticus adversely affected the outcome.

The spectrum of central nervous system manifestations in leprosy: a systematic review of published case reports and case series.

BACKGROUND: This systematic review aimed to investigate central nervous system (CNS) involvement in leprosy by analysing multiple cohort studies, individual cases and case series. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. PubMed, Scopus and Embase databases were searched up to 8 July 2023, using a predefined search strategy. Inclusion criteria included patients diagnosed with leprosy with evidence of CNS involvement. The quality of the included cases was evaluated using the Joanna Briggs Institute checklist. RESULTS: A total of 34 records were identified, including 18 cohort studies and 16 reports describing 27 isolated cases. Autopsies revealed macroscopic changes in the spinal cord, neurofibrillary tangles and senile plaques. Mycobacterium leprae was detected in neurons of the medulla oblongata and spinal cord using PCR and phenolic glycolipid 1 staining. Cerebrospinal fluid (CSF) analysis showed inflammatory changes, increased gamma globulins and detection of Mycobacterium leprae antigens and antibodies. In 21 patients (78%), spinal cord/brachial plexus abnormities were detected. In the majority, MRI revealed T2/fluid-attenuated inversion recovery (FLAIR) hyperintensity in the cervical cord. In patients with brainstem involvement, T2/FLAIR hyperintensity was noted in the cerebellar peduncles, facial nerve nuclei and/or other cranial nerve nuclei. Brain parenchymal involvement was noted in three patients. CONCLUSIONS: This systematic review provides evidence of CNS involvement in leprosy, based on autopsy findings, neuroimaging, CSF analysis and neurophysiological studies.

The etiological spectrum of multiple ring-enhancing lesions of the brain: a systematic review of published cases and case series.

OBJECTIVE: Multiple ring-enhancing lesions of the brain are enigmatic neuroimaging abnormality. In this systematic review, we evaluated the etiological spectrum of these lesions. METHODS: This systematic review adhered to the PRISMA guidelines. We searched PubMed, Embase, Scopus, and Google Scholar up until 15 June 2023. We included case reports and case series. Quality evaluation of each case was based on selection, ascertainment, causality, and reporting. The extracted information included demographic characteristics, clinical features, type and number of multiple enhancing brain lesions, diagnostic procedures, final diagnoses, treatments, and patient outcomes. PROTOCOL REGISTRATION: PROSPERO CRD42023437081. RESULTS: We analyzed 156 records representing 161 patients, 60 of whom were immunocompromised. The mean age was 42.6 years, and 67% of patients experienced symptoms for up to 1 month. A higher proportion of immunocompromised patients (42% vs. 30%) exhibited encephalopathy. Chest or CT thorax abnormalities were reported in 27.3% of patients, while CSF abnormalities were found in 31.7%, more frequently among the immunocompromised. Definitive diagnoses were established via brain biopsy, aspiration, or autopsy in 60% of cases, and through CSF examination or other ancillary tests in 40% of cases. Immunocompromised patients had a higher incidence of Toxoplasma gondii infection and CNS lymphoma, while immunocompetent patients had a higher incidence of Mycobacterium tuberculosis infection and immune-mediated and demyelinating disorders. The improvement rate was 74% in immunocompetent patients compared to 52% in the immunocompromised group. CONCLUSION: Multiple ring-enhancing lesions of the brain in immunocompromised patients are more frequently caused by Toxoplasma gondii infections and CNS lymphoma. Conversely, among immunocompetent patients, Mycobacterium tuberculosis infection and immune-related demyelinating conditions are common.

Utility of CD34 in Assessing Microvessel Density and Its Correlation With Clinicopathological Parameters in Colorectal Carcinoma Patients.

Currently, the most commonly practiced method of reporting cases of colorectal carcinoma is done according to guidelines provided by the College of American Pathologists (8th edition) and the Royal College of Pathologists (UK). These guidelines include various histopathological parameters like tumor site, extent, histologic type, grade, margins, tumor budding, lymphovascular invasion, and perineural invasion. However, in the present guidelines, the immunohistochemistry-based marker of mean vessel density (MVD) has not been addressed as an important parameter. The present study gives an overview of the importance of MVD. MVD was statistically significant when correlated with tumor size, lymph node metastasis, grade, and vascular invasion. However, no statistical significance was observed when compared with age, perineural invasion, and stage of the tumor.

In vitro production of steroidal saponin, total phenols and antioxidant activity in callus suspension culture of Paris polyphylla Smith: an important Himalayan medicinal plant.

Paris polyphylla Smith (Melanthiaceae) family, which is native to the Himalayan region, has received a lot of attention recently due to its extensive history of usage in traditional medicine. The production of steroidal saponin from callus suspension cultures of P. polyphylla was observed in the current study. The current study attempted to develop a P. polyphylla plant callus suspension culture through optimization of cultivation technique for callus suspension, quantification of total phenolic components and estimation of the extract's antioxidant activity. A light-yellow callus was formed within six weeks of cultivating rhizomes on Murashige and Skoog (MS) media supplemented with Thidiazuron (TDZ). Furthermore, the effect of TDZ, Methyl Jasmonate (MeJA), and Yeast Extract (YE) on callus growth, steroidal saponin (dioscin and diosgenin), total phenolic content, total flavonoids, total tannin, and total antioxidant activity was also measured. The medium containing 0.5 µM TDZ depicted the maximum callus biomass (2.98 g fresh weight). Significantly high phenolic and tannin content was observed in the MS medium containing 50 µM MeJA, whereas, no significant increase was observed in total tannin production in any treatment. Three in vitro assays, DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2'-azino-bis (3-ethylbenzothiazoline- 6-sulfonic acid)) and FRAP (ferric ion reducing antioxidant potential) and FC (Folin-Ciocalteu), were used to assess antioxidant potential of callus. Maximum antioxidant analysis reported in 1.0 µM TDZ (6.89 mM AAE/100 g) containing medium followed by 50 µM MeJA (6.44 mM AAE/100 g). The HPLC analysis showed a high presence of dioscin and diosgenin (5.43% and 21.09%, respectively) compared to the wild sample (2.56% and 15.05%, respectively). According to the results, callus produced on media supplemented with 50 µM MeJA have significant phenolic contents and elevated antioxidant activity; nevertheless, callus growth was greater in the presence of 0.5 µM TDZ. The findings of the current study have commercial implications since greater biomass production will result in active phytochemicals that the pharmaceutical and nutraceutical sectors are in need desperately.

Bilateral Vision Loss and Visual Hallucinations in Subacute Sclerosing Panencephalitis: A Case Report.

We report an interesting case of visual loss and visual hallucinations in a 37-year-old man. He presented with decreased vision in both eyes and visual hallucinations for the last one and a half months. He also had multiple focal to bilateral tonic-clonic seizures. On examination, there was no perception of light rays in both eyes. Fundus examination revealed disc oedema with peripapillary small haemorrhages in both eyes. Initially, the discs were hyperaemic, which turned pale in the subsequent examination at 1 month. Magnetic resonance imaging (MRI) of the brain revealed T2 hyperintensities in periventricular white matter and right fronto-parietal-occipital gray matter. His electroencephalogram showed intermittent slowing. His cerebrospinal fluid (CSF) examination showed five cells (all lymphocytes), protein 50 mg/dl, sugar 76 mg/dl (corresponding blood sugar 90 mg/dl). His CSF specimen was positive for anti-measles IgG antibodies. In conclusion, acute vision loss can rarely be the presenting symptom and, therefore, SSPE should also be considered in differential diagnoses of acute vision loss in measles-endemic regions.

Transcriptomics and Proteomics Approach for the Identification of Altered Blood microRNAs and Plasma Proteins in Parkinson's Disease.

Parkinson's disease (PD) is a neurodegenerative disorder caused by the selective destruction of dopaminergic neurons (DA-nergic). Clinically, PD is diagnosed based on developing signs and symptoms. A neurological and physical examination and sometimes medical and family history also help in the diagnosis of PD. However, most of these features are visible when more than 80% of the dopaminergic neurons have degenerated. An understanding of the selective degeneration process at the cellular and molecular level and the development of new biomarkers are required for effective PD management. Several studies have been carried out using a selected set of miRNAs/ mRNAs and proteins to develop biomarkers of PD; however, an unbiased and combined miRNA-protein profiling study was required to identify the markers of progressive and selected degeneration of dopaminergic neurons in PD patients. In the present study, we have carried out global protein profiling through LC-MS/MS and miRNA profiling by using a "brain-specific" miRNA array panel of 112 miRNAs in PD patients and healthy controls to find the unprejudiced group of proteins and miRNAs that are deregulating in PD. In the whole blood samples of PD patients compared to healthy controls, the expression of 23 miRNAs and 289 proteins was significantly increased, whereas the expression of 4 miRNAs and 132 proteins was considerably downregulated. Network analysis, functional enrichment, annotation, and analysis of miRNA-protein interactions were also performed as part of the bioinformatics investigation of the discovered miRNAs and proteins revealing several pathways that lead to PD development and pathogenesis. Based on the analysis of miRNA and protein profiling, we have identified four miRNAs (hsa-miR-186-5p, miR-29b, miR-139 & has-miR-150-5p) and four proteins (YWHAZ, PSMA4, HYOU1, & SERPINA1), which can be targeted for the development of new biomarkers of PD. In vitro studies have identified the role of miR-186-5p in regulating the levels of the YWHAZ/YWHAB & CALM2 gene, which has shown maximum downregulation in PD patients and is known for its role in neuroprotection from apoptotic cell death & calcium regulation. In conclusion, our research has identified a group of miRNA-proteins that can be developed as PD biomarkers; however, future studies on the release of these miRNAs and proteins in extracellular vesicles circulating in the blood of PD patients can further validate these as specific biomarkers of PD.

Tumor Necrosis Factor-α, CD1A and CD1E Genetic Polymorphisms in Guillain-Barré Syndrome: A Study from India.

Background: Guillain-Barré Syndrome (GBS) is an acute acquired autoimmune inflammatory disorder of peripheral nerves and roots. The pathogenesis is essentially an aberrant post-infectious immune response in a genetically susceptible host milieu. Single nucleotide polymorphisms (SNP) in genes encoding the inflammatory mediators like TNF-α, CD1A and CD1E can influence their expression and level and the susceptibility and clinical course of disease in GBS. Objective: We tried to study the susceptibility of single nucleotide polymorphisms of TNF-α and CD1 genes in Guillain-Barré Syndrome in Indian population and determine the association in terms of genotype, allele and haplotype distribution along with individual subtype, severity and clinical outcome. Methodology: In this case-control study, we investigated the single nucleotide polymorphism pattern in the promoter region of TNF-α (-308 G/A), TNF-α (-863C/A), CD1A and CD1E genes using real-time polymerase chain reaction in 75 GBS patients and analysed in comparison with 75 age and sex-matched healthy controls. Results: The findings revealed that the allelic distribution of TNF-α (-308 G/A) *A allele was associated with GBS (P value 0.04, Odds Ratio 2.03, 95% Confidence Interval 1.01-4.07). There was no association found with genotype, haplotype combination and other allele distribution for GBS in the study. CD1A and CD1E SNPs did not reveal any susceptibility for GBS. The subtype analysis did not reveal any statistical significance, except for CD1A *G allele with AMAN subtype (P value 0.026). The haplotypic combinations and mutant allele of TNF-α (-308 G/A), TNF-α (-863C/A), CD1A and CD1E were significantly associated with severe GBS in the study. However, there was no association of any SNP for mortality and survival of GBS in the study. Conclusion: TNF-α (-308 G/A)*A allele might confer genetic susceptibility for GBS in Indian population. CD1 genetic polymorphism could not be considered for susceptibility to GBS. TNF-α and CD1 genetic polymorphism did not affect mortality in GBS.

Impact of comorbid psychogenic non-epileptic seizures on migraine: An observational study.

Objectives: There is a bidirectional and complex interplay between psychiatric comorbidities and migraine. Migraine has been observed in 50-60% of patients with psychogenic non-epileptic seizures (PNES). Studies describe migraine as a medical comorbidity in PNES. However, there are limited studies on impact of PNES on migraine. We aim to see the impact of PNES on migraine. Materials and Methods: This cross-sectional and observational study was conducted at a tertiary-care center from June 2017 to May 2019. Fifty-two patients with migraine with PNES and 48 patients with migraine without PNES were included on the study. Migraine and PNES were diagnosed based on International Classification of Headache Disorders-3 (ICHD-3) and International League Against Epilepsy (ILAE) criteria, respectively. Headache intensity was assessed using visual analog scale. Comorbid depression, anxiety, and somatoform-symptom-disease were assessed using the Generalized Anxiety Disorder-7 Scale, Patient Health Questionnaire-9, and DSM-5 criteria, respectively. Results: Females were common in both groups and the difference was statistically insignificant. Headache frequency was significantly more in patients with migraine with PNES (P < 0.05). However, headache intensity was similar in both groups. Patients with headaches and PNES identified triggers less commonly except for stress. Depression and somatoform symptom disorder were significantly more common in patients with migraine with PNES. Abnormal neurocircuitry involving frontal, limbic, and thalamic regions due to comorbid PNES may cause central sensitization, resulting in frequent migraine headaches which is further augmented by coexisting depression and somatoform-symptom-disease. Conclusion: Migraine with PNES patients suffers more frequent headaches than patients with migraine without PNES. They differ in various headache triggers, with mental stress being the predominant trigger.

Case Report: An Unusual Case of Subacute Sclerosing Panencephalitis with Distinctive Clinical and Neuroimaging Features.

Subacute sclerosing panencephalitis (SSPE) is a relentlessly progressive brain disorder with invariable mortality. Subacute sclerosing panencephalitis is common in measles-endemic areas. We report an unusual SSPE patient with distinctive clinical and neuroimaging features. A 9-year-old boy came with a 5-month history of spontaneously dropping objects from both hands. Subsequently, he developed mental decline, a loss of interest in his surroundings, decreased verbal output, and inappropriate crying and laughing along with generalized periodic myoclonus. On examination, the child was akinetic mute. The child demonstrated intermittent generalized axial dystonic storm with flexion of upper limbs, an extension of lower limbs, and opisthotonos. Dystonic posturing was more dominant on the right side. Electroencephalography revealed periodic discharges. Cerebrospinal fluid antimeasles IgG antibody titer was markedly elevated. Magnetic resonance imaging revealed marked diffuse cerebral atrophy, and periventricular T2/fluid-attenuated inversion recovery hyperintensity. T2/fluid-attenuated inversion recovery images also revealed multiple cystic lesions present in the region of periventricular white matter. The patient was given a monthly injection of intrathecal interferon-α. The patient is currently continuing in the akinetic-mute stage. In conclusion, in this report, we described an unusual case of acute fulminant SSPE in which neuroimaging demonstrated unusual multiple small discrete cystic lesions in the cortical white matter. The pathological nature of these cystic lesions currently is not clear and needs to be explored.

Obstetric outcomes in pregnant women with subacute sclerosing panencephalitis (SSPE): a systematic review of case reports and case series.

BACKGROUND: Subacute sclerosing panencephalitis (SSPE) is a devastating brain disease caused by persistent infection by the measles virus. Several cases of SSPE in pregnant ladies have been described. This systematic review is focused on maternal and foetal outcomes among pregnant women with SSPE. METHODS: We searched four databases (PubMed, Embase, Scopus, and Google Scholar). We reviewed all relevant cases, published until 14 August 2022. The review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The protocol was registered with PROSPERO (CRD42022348630). The search items that we used were "((Pregnancy) OR (delivery)) AND (Subacute sclerosing panencephalitis (SSPE))". Dyken's criteria were used for the diagnosis of SSPE in pregnant women. The extracted data was recorded in an Excel sheet. The Joanna Briggs Institute Critical Appraisal tool for case reports was used to assess the quality of published cases. RESULTS: We came across 19 reports describing details of 21 cases. The age of SSPE-affected women varied from 14 to 34 years (mean 23 years). In the majority (n=14), clinical manifestations were started in the antepartum period. Nine pregnant SSPE women presented with vision loss. After delivery, 13 SSPE-affected women died. On the contrary, 15 foetuses, though the majority were preterm, were alive. Five foetuses either died soon after birth or were still-born. CONCLUSION: In conclusion, SSPE in pregnancy is often missed, as it mimics eclampsia. SSPE in pregnancy usually has a devastating course. Universal early childhood measles vaccination is the only way to fight this menace.

Role of gut microbiota in tumorigenesis and antitumoral therapies: an updated review.

Gut microbiota plays a prominent role in regulation of host nutrientmetabolism, drug and xenobiotics metabolism, immunomodulation and defense against pathogens. It synthesizes numerous metabolites thatmaintain the homeostasis of host. Any disbalance in the normalmicrobiota of gut can lead to pathological conditions includinginflammation and tumorigenesis. In the past few decades, theimportance of gut microbiota and its implication in various diseases, including cancer has been a prime focus in the field of research. Itplays a dual role in tumorigenesis, where it can accelerate as wellas inhibit the process. Various evidences validate the effects of gutmicrobiota in development and progression of malignancies, wheremanipulation of gut microbiota by probiotics, prebiotics, dietarymodifications and faecal microbiota transfer play a significant role.In this review, we focus on the current understanding of theinterrelationship between gut microbiota, immune system and cancer,the mechanisms by which they play dual role in promotion andinhibition of tumorigenesis. We have also discussed the role ofcertain bacteria with probiotic characteristics which can be used tomodulate the outcome of the various anti-cancer therapies under theinfluence of the alteration in the composition of gut microbiota.Future research primarily focusing on the microbiota as a communitywhich affect and modulate the treatment for cancer would benoteworthy in the field of oncology. This necessitates acomprehensive knowledge of the roles of individual as well asconsortium of microbiota in relation to physiology and response ofthe host.
