Common microRNAs in Epilepsy and Migraine: Their Possibility as Candidates for Biomarkers and Therapeutic Targets during Comorbid Onset of Both Conditions.

Epilepsy and migraine are chronic neurological disorders with shared clinical as well as pathophysiological mechanisms. Epileptic patients are at a higher risk of developing migraine compared to normal individuals and vice versa. Several genetic and environmental risk factors have been reported to be associated with the development of both diseases. Previous studies have already established standard genetic markers involved in various pathways implicated in the pathogenesis of both these comorbid conditions. In addition to genetic markers, epigenetic markers have also been found to be involved in the pathogenesis of epilepsy and migraine. Among the epigenetic markers, miRNAs have been explored at length and have emerged as significant players in regulating the expression of their target genes. miRNAs like miR-22, miR-34a, miR-155, miR-211, and Let-7b play a significant role in neuronal differentiation and seem to be associated with epilepsy and migraine as comorbid conditions. However, the exact shared mechanisms underlying the role of these miRNAs in these comorbid conditions are still unclear. The current review has been compiled with an aim to explore common microRNAs targeting the genes involved in shared molecular pathways leading to epilepsy and migraine as comorbid conditions. The new class of ncRNAs, i.e., tRNA transfer fragments, are also discussed. In addition, their role as potential biomarkers and therapeutic targets has also been evaluated. However, limitations exist, and based on the current literature available, only a few microRNAs seem to be involved in the pathogenesis of both these disorders.

Acute Kidney Injury in Acute Myocardial Infarction and Its Outcome at 3 and 6 Months.

Epidemiological data on the prevalence of acute kidney injury (AKI) in acute coronary syndrome are sparse, with most studies having been conducted retrospectively. This study prospectively analyzed the incidence of AKI in patients with acute myocardial infarction (AMI) and to identify the risk factors for AKI and their renal outcome at 3 and 6 months. This was a prospective and observational study, which enrolled 120 patients presenting with their first episode of AMI to our hospital and consented to the study. Renal function tests were performed at admission, at 48 h, and at follow-up at 3 and 6 months. The majority of the patients underwent a percutaneous coronary intervention (59.2%), 21.7% received thrombolytic therapy, and 19.2% were managed conservatively. At 48 h, 11 patients had AKI. At 3 months, 8 patients had died, and renal dysfunctions were seen in 9 out of 112 patients. At 6 months, 12 patients out of 112 had renal dysfunction. There was no difference in the incidence of AKI in patients with an estimated glomerular filtration rate above and below 60 mL/min/1.73 m2. Killip Class 4 and diabetes mellitus were associated with an increased incidence of renal dysfunction in AMI patients. The type of treatment and the use of a contrast agent in the coronary intervention did not affect the development of AKI. According to this study, if indicated, a percutaneous coronary intervention should not be denied to patients for fear of developing AKI. This needs to be examined in larger randomized trials.

Correlation of Portal Vein Diameter as a Reflection of Portal Hypertension With Clinical and Laboratory Parameters in Chronic Liver Disease.

Chronic liver disease (CLD) patients develop portal hypertension which lead to complications like splenomegaly, ascites and esophageal varices. Portal hypertension is defined as hepatic venous pressure gradient more than 5mmHg, being invasive it is difficult to measure. Some studies show that increased portal vein diameter (PVD) on ultrasonography correlate with oesophageal varices and can indicate portal hypertension. Studies correlating PVD with other complications of portal hypertension like ascites and spleen size are lacking. Aim of this study was to correlate portal vein diameter with ascites, spleen size, thrombocytopenia and prognostic markers like Child-Turcotte Pugh (CTP) score and Model for End stage Liver Disease (MELD) score in Chronic liver disease patients. MATERIAL: This was a cross-sectional observational study of patients with Chronic liver disease conducted at tertiary care teaching hospital. All patient underwent clinical history, examination, blood testing and ultrasonography. Data collected was analysed by using statistical tests. OBSERVATION: Out of 97 CLD patients taken in study, the mean age of patients was 47.39 ± 12.64 year and majority were male (75.3%). Most common etiological factor was alcohol (in 53.7%). On clinical examination, 55.7% patients had pallor, 54.6% had icterus. Chest radiograph shows pleural effusion in 14.4% patients. Mean portal vein diameter was found to be 12.31 ± 2.71mm. Correlation coefficient of portal vein diameter with spleen size was 0.3 with p value of 0.004 suggesting a positive correlation. Parameters like thrombocytopenia, CTP score and MELD score correlation coefficient was -0.2(p-value: 0.066), 0.1(p value: 0.463) and 0.0(p-value: 0.725) respectively. The mean of PVD(mm) in ascites group was 12.43 and non ascites group was 11.92. Strength of association was 0.08 (Point Biserial correlation) indicating no association. CONCLUSION: Portal vein diameter had positive correlation with spleen size which is statistically significant in our study. No significant correlation was observed between PVD with ascites, thrombocytopenia, CTP score and MELD score.

Facial Nerve Palsy with Total Ophthalmoplegia; a Novel Presentation of Fungal Invasion.

Mucormycosis is an expeditious invasion of a fungus of angioinvasive nature, predominant in immunocompromised individuals, often leading to organ malfunction and loss. Facial nerve involvement and total ophthalmoplegia are its rare presentations. Early detection and treatment can alter natural disease course and prevent potential catastrophic outcomes in diabetic patients. Facial nerve palsy is mostly attributed to peripheral neuropathy in patients with advanced diabetes mellitus. It rarely raises alarm about an invasive fungal infection. Here, we report the case of a 38-year-old male with type 2 diabetes mellitus, who presented to us with left lower motor neuron type facial palsy and left-sided total ophthalmoplegia due to invasive rhino-orbito-cerebral mucormycosis (ROCM). Despite aggressive measures, including antifungal therapy and repeated endoscopic debridement, he subsequently developed central retinal artery occlusion (CRAO) and underwent left eye exenteration.

Bilateral Renal Replacement Lipomatosis: A Case Report on Rare Complication of Obstructive Uropathy.

Renal replacement lipomatosis (RRL) is an uncommon complication, leading to the fatty replacement of the renal parenchyma. Various etiologies have been described for this long-term infirmity, but obstructive uropathy is one paramount cause. Previously described reports have documented unilateral disease in the majority, but we are narrating a case of bilateral RRL, which is very scarce in the literature. A 57-year-old man, who was a known case of obstructive uropathy, presented to us with the symptoms of urinary tract infection. In imaging evaluation, the patient was found to have bilateral RRL.

Epilepsy and Migraine Shared Genetic and Molecular Mechanisms: Focus on Therapeutic Strategies.

Epilepsy and migraine are both episodic disorders and share clinical as well as pathophysiological mechanisms. The prevalence of epilepsy in migraine patients is generally higher than normal as compared to general population and vice versa. Various environmental risk factors and genetic factors have been reported to be associated with susceptibility of these comorbid diseases. Specific genes have been implicated in the pathogenesis of the two diseases. However, the shared genetic susceptibility has not been explored extensively. Previous studies have reported that the alterations in the genes encoding ion channel proteins are common risk factors for both the diseases. The alterations in ion channel-encoding genes CACNAIA (T666M) and SCNIA (Q1489K and L1649Q) have been found to be involved in the development of familial hemiplegic migraine (FHM) as well as generalized epilepsy and some cases of focal epilepsy as well. The fact that both these disorders are treated with anti-epileptic drugs (AEDs) strongly supports common underlying mechanisms. This review has been compiled with an aim to explore the alterations in common genes involved in various pathways regulating neuronal hyperexcitability, a common risk factor for both these conditions. The avenue for future treatment strategies targeting common genes and molecular mechanisms has also been discussed.

MRI Spectrum of Haemophilus influenzae Meningoencephalitis in Children.

BACKGROUND AND PURPOSE: Haemophilus influenzae type b (Hib) infection occurs mostly in children and is transmitted from person to person through the respiratory pathway. Hib strain is associated with meningitis or encephalitis. It is not an uncommon infection, particularly, in the developing world. This prospective cohort study was done with the aim of describing imaging findings in patients with Hib meningoencephalitis. MATERIALS AND METHODS: In a prospective cohort study, consecutive children admitted in the pediatric emergency unit with acute febrile encephalopathy were enrolled. The clinical details, CSF analysis, and microbiological and serological investigations were recorded on a case record proforma. Children with confirmed Hib meningoencephalitis were included in this study. Clinicoradiological features were assessed. RESULTS: A total of 16 patients with acute febrile encephalopathy, in whom CSF latex agglutination, CSF culture, or CSF multiplex PCR were positive for H. influenzae were included in this study. All these children were investigated with magnetic resonance imaging (MRI) brain. Important imaging findings were meningitis, predominantly around frontoparietal lobes (43%), cerebritis (28%), ventriculitis (14%), and subdural collections (21.5%). One patient had features consistent with acute disseminated encephalomyelitis (ADEM) while four patients had normal MRI scan. CONCLUSIONS: H. influenzae is still a common cause of meningitis in infants and children in the developing world. We have tried to study the most common MRI features associated with Hib infection to help radiologists alert the treating clinicians to further investigate these patients for appropriate prognostication.

Brain MRI in Epstein-Barr Virus Meningoencephalitis in Children.

BACKGROUND AND PURPOSE: Epstein-Barr virus (EBV) meningoencephalitis can have variable and nonspecific brain magnetic resonance imaging (MRI) findings in children. This study was done with the purpose of describing brain MRI findings in children with EBV meningoencephalitis. MATERIALS AND METHODS: The study included 45 pediatric patients that presented with variable neurological symptoms and were found to have EBV meningoencephalitis based on positive EBV deoxyribonucleic acid (DNA) in the cerebrospinal fluid. All these patients had undergone brain MRI. Clinical and radiological features were evaluated. RESULTS: Fever was a presenting feature in all cases. Signs of meningitis and raised intracranial pressure (ICP) were seen in 24 (53.3%) cases, encephalopathy in 15 (33.3%), and seizures were present in 33 (73.3%). MRI was abnormal in 29 (64.4%) patients. The cortical/subcortical pattern was diagnosed in 9 (20%) cases, white matter involvement in 7 (15.5%), basal ganglia in 5 (11.1%), thalamic involvement in 4 (8.8%), brain stem involvement in 2 (6.2%), substantia nigra involvement in 2 (4.4%), and cerebellar involvement in 2 (4.4%). Diffusion restriction was present in 11 (24.4%) cases and susceptibility changes in 7 (15.5%). Meningeal enhancement was present in 10 (22.2%) cases. In addition, brain abscess and subdural effusion/empyema were present in 1 (2.2%) case each. CONCLUSION: Pediatric EBV meningoencephalitis has varied clinicoradiological spectrum and there is no specific MRI pattern to characterize the meningoencephalitis on imaging. Common MRI findings include cortical-subcortical involvement, white matter changes, basal ganglia, and thalamic involvement.

Crosstalk between T Helper Cell Subsets and Their Roles in Immunopathogenesis and Outcome of Polytrauma Patients.

PURPOSE: One of the leading causes of morbidity and early-age mortality across the globe is trauma. It disrupts immune system homeostasis and intensely affects the innate and adaptive immune responses, predisposing patients to posttrauma complications and poor outcomes. Most of the studies on posttrauma cellular immune response have been centered on the T helper-1-T helper-2 imbalances after trauma. This study was conducted to understand the role of circulating novel T helper cells in the acute posttraumatic period and clinical outcome of trauma patients. MATERIALS AND METHODS: Signature cytokines and transcription factors of circulating Th (T helper)-9, Th-17, Th-22, and regulatory T helper cells were studied using flowcytometry along with serum biomarkers in 49 patients with polytraumatic injuries admitted to a tertiary care hospital. The patients were followed up until their outcome. The results were correlated with their clinical outcomes. RESULTS: In patients who died, higher nTreg, iTreg, Tr1 (early-phase), and higher IRF4+Th-9, IL17+ Th-17, and RORγT+ Th-17 (mid-phase) were seen. However, by the late phase, only RORγT+ Th-17 remained higher. Serum IL-6 and PCT were found to be consistently higher. In survivors, higher Th-3 (early phase), Th-22 (mid-phase), and IRF4+Th-9, IL17+ Th-17, nTreg, Th-3 (late phase) were observed to have played a protective role. Serum IL-2, IL-4, IL-17A and IL-22 were significantly higher in survivors. CONCLUSION: Different T helper subsets were observed to be playing pathogenic and protective roles in different phases of trauma and could be used for early prognostication and make way for noninvasive management of critically injured trauma patients by immunomodulation.

Impact of monocytic cytokines in polytrauma patients with orthopedics injures.

OBJECTIVE: Orthopedic injuries are a growing epidemic affecting predominantly, the young population, after trauma. Polytrauma patients with a femoral fracture and with Injury Severity Score of >15 are of special concern because of complications like Systemic inflammatory response syndrome (SIRS), Multi-organ dysfunction syndrome (MODS) and sepsis. Against this background. We aimed to assess the role of monocytic cytokines in the development of complications in patients, having isolated diapheseal fracture of femur as compared to those having diapheseal fracture of femur along with ISS score >15. METHODOLOGY: Patients were divided into to two groups: in first group, only those patients who had isolated femur fracture were included (named as 'Group A'). In the second groups patients having femur fracture along with ISS >15 at the time of admission (named as 'Group B'), were included. The study used flowcytometry based intracellular cytokine assay to circumvent the problem associated with extracellular cytokine assay. RESULTS AND CONCLUSION: A total of 20 patients aged between 20 and 55 years, presenting to the emergency department within 24 h of injury were enrolled in Group 'A' and 'B' as per criteria mentioned above. Intracellular expression of cytokines in isolated femur fracture tends to normalize towards healthy control in the late phase of trauma. Elevated levels of IL-8 and IL-6 levels in late phase (Day 10) of trauma. IL-8 and IL-6 may increases to compensate the higher levels of IL-1ß. The effect of cytokines on the severity of injury was observed. This complex action of immune cells and proinflammatory cytokines were seen in initial and later stage of trauma.

Pathogen burden & associated antibiogram of Pseudomonas spp. in a tertiary care hospital of India.

Antimicrobial resistance particularly in Gram-negative bacilli is an increasing problem worldwide. Pseudomonas spp. is one the most common Gram-negative bacteria associated with nosocomial infections and therefore, its trend of antimicrobial resistance needs to be studied. The aim of this study was to evaluate the rate of antimicrobial resistance and changes in resistance pattern over a period of five years (2012-2016) in Pseudomonas spp. isolated from trauma patients attending a tertiary care hospital in north India. During the study, a total of 2444 Pseudomonas spp. were isolated from the various clinical sample. The most common species isolated was P. aeruginosa (2331, 95%). The highest level of resistance was observed against levofloxacin (1678, 69%) and the lowest level of resistance was observed against tobramycin (1254, 51%). Irrational and inappropriate use of antibiotics was found to be responsible for multidrug resistance in Pseudomonas spp. Hence, there is an urgent need to emphasize strict antibiotic policy to minimize the misuse of antimicrobials.

Protocol for developing a surveillance system for surgical site infections.

Purpose: Healthcare-associated infections (HCAIs/ HAIs) are the most common adverse occurrences during health care delivery. Across the globe, millions of patients are affected by HAIs annually, with a higher burden and impact in developing nations. a major lacuna in planning preventing protocols is the absence of National Surveillance Systems in most low-middle income countries, which also prevents allocation of resources to the high-priority areas. Among all the HAIs, there is a huge global burden of SSIs, in terms of morbidity, prolonged hospital stays, increased antimicrobial treatment as well as attributable mortality. Method: This manuscript details the process of establishment of an SSI surveillance protocol at a level-1 trauma centre in North India. Result and Conclusion: Surveillance is an essential tool to reduce this burden. It is also an important primary step in recognizing problems and priorities, and it plays a crucial role in identifying risk factors for SSI and to be able to target modifiable risk factors. Therefore, it is imperative to establish reliable systems for surveillance of HAIs, to regularly estimate the actual burden of HAIs, and to use these data for developing indigenous preventive measures, tailored to the country's priorities.

T-helper-17, Regulatory T-helper Cells Related Serum Markers and IL-13 in the Outcome of Polytraumatic Patients with Bacteremia.

BACKGROUND: Bacteremia and sepsis are associated with high mortality, increased hospital stays, and associated costs, especially in trauma patients. Sepsis is a fatal immunological disorder and its pathophysiology is still poorly understood. OBJECTIVE: To ascertain the role of T-helper lymphocyte-related inflammatory serum cytokines in trauma patients with blood culture positive with Gram-negative bacteria. METHODS: Peripheral blood samples (5 ml) were collected from 40 trauma patients on the day of obtaining positive blood culture (i.e., day 0), followed by an appropriate antimicrobial treatment and sample acquisition on day 4 and only once from 40 age-matched healthy controls. Bead-based cytometric analysis was used to quantify extracellular levels of 16 serum cytokines. The cytokine profiles were compared with those in healthy controls and then correlated to clinical outcomes. RESULTS: A total of 40 patients were enrolled during the study period. Of these, 24 patients (60%) were discharged while 16 (40%) had a fatal outcome. Statistically significant elevated levels of serum IL-6, IFN-γ, TNF-α, IL-17A, IL-17F, and IL-4 were observed in septic patients, while lowered IL-13 levels correlated significantly with a favorable outcome. CONCLUSION: Sepsis following trauma elicits a heightened immune response in the body and provokes the production of a diverse array of cytokines that is both pro-inflammatory and anti-inflammatory. However, the unique cytokine profile of septic trauma patients is still not well understood.

Prevalence, etiology, and antibiotic resistance profiles of bacterial bloodstream infections in a tertiary care hospital in Northern India: A 4-year study.

INTRODUCTION: Bloodstream infections (BSIs) can lead to life-threatening sepsis and are globally associated with high morbidity and mortality. Although BSIs require immediate antimicrobial treatment, their prevalence, etiology, and antimicrobial susceptibilities differ from one country to other. There is a dearth of such data from India. Here, we report the 4-year etiologic data on BSI in trauma patients admitted to a tertiary care referral hospital in New Delhi, India. MATERIALS AND METHODS: A retrospective study was conducted at the trauma center between January 2013 and December 2016. The routine microbiological data on bacterial BSI were recorded and determined retrospectively from the laboratory records. Antimicrobial susceptibility profiles were statistically analyzed. RESULTS: A total of 2017 bacterial strains isolated from blood culture samples were included for microbiological analysis. During the study, the median age of the patients varied from 30 to 35 years, with the percentage of females in the study population varying from 17% to 19%. The predominant pathogens were Gram-negative bacteria, with Acinetobacter species, followed by Klebsiella species being the most commonly isolated organisms throughout the 4 years of study. Among Gram-positive isolates, Staphylococcus species were the leading pathogens (11%-15%). CONCLUSIONS: A detailed analysis of prevalence, etiology of BSIs in India and its resistance profile is crucial for appropriate antibiotic use, clinical management, and formulation of antibiotic policies and preventive measures.

Pattern of antimicrobial resistance of Gram-negative bacilli in surgical site infections in in-patients and out-patients at an apex trauma Center: 2013-2016.

INTRODUCTION: Antimicrobial resistance is an increasing problem worldwide especially among the surgical site infections (SSIs). SSI is becoming more serious due to hospital-acquired infections/nosocomial infections, which further leads to the overuse of broad-spectrum antibiotics. To investigate the antimicrobial resistance patterns among Gram-negative bacteria in SSI in in- and out-patients the present study was designed. METHODOLOGY: During the 4 years (January 2013-December 2016), the antimicrobial resistant pattern was studied in the admitted patients and in the patients who were followed up to the outpatients department (OPD) after discharge. Antimicrobial resistance pattern testing was done by the disk diffusion method on Mueller-Hinton agar and by E-test for ten antibiotics according to The Clinical and Laboratory Standards Institute guidelines for Gram-negative bacilli. RESULTS: A total of 2,447 strains were isolated from the studied population on over the period of 4 years. Of 2447, 1996 (81%) were isolated from patients who had SSI during the hospital stay, and 451 (18%) were from patients who attended the OPD after discharge. In the outpatients, who followed up in the OPD for the SSI, Escherichia coli (148), and Pseudomonas aeruginosa (93), whereas in the patients who develop SSI during their hospital stay, Acinetobacter baumannii (622), E. coli (424), and Klebsiella pneumoniae (315) were found to be common. A very high resistance pattern was observed in both the studied groups; however, a higher resistance pattern was seen in in-patients as compared to outpatients. CONCLUSION: In our study, we have reported resistance pattern in Gram-negative bacteria isolated from the patients who were came for the follow as well as in the inpatients. For the outpatients, it can be concluded that it could be a community-acquired infection which is also an alarming condition for our society.

CD14+ Monocytic Cytokines: Impact on Outcome in Severely Injured Patients.

INTRODUCTION: Trauma is one of the leading causes of mortality worldwide. Trauma patients, who presented to the hospital casualty department within 24 h of injury, further admitted to the Surgical Intensive Care Unit were enrolled in this study. MATERIALS AND METHODS: The aim was to study the peripheral blood monocyte activity to produce tumor necrosis factor (TNF-α), interleukin-1 (IL-1) ß, IL-6, and IL-8 in severely injured patients after trauma. RESULT: A total of 28 polytrauma patients were enrolled and observed that the levels of TNF-α, IL-1 ß, IL-6, and IL-8 were significantly decreased and levels of IL-8 were increased in the fatal patients compared to the healthy controls. CONCLUSION: After trauma, an immediate hyperactivation of circulating monocytes is rapidly followed by a substantial paralysis of cell function. Decreased activity of monocytes can be used to identify potential fatal immunological disruption. Since immunological disruption occurs before clinical symptoms; our study proposes an immunological prognostication score for trauma victims.

Multiple mutations in lipid-A modification pathway & novel fosA variants in colistin-resistant Klebsiella pneumoniae.

AIM: To investigate antimicrobial resistance mechanisms in a cluster of colistin-resistant Klebsiella pneumoniae. METHODS: Antimicrobial susceptibility was tested by disk diffusion and broth microdilution. Whole-genome sequencing and genome analysis were performed. RESULTS: The eight colistin-resistant K. pneumoniae isolates belonged to three different clones (ST11, 14 and 231). The eptA and arnT genes from lipid modification pathway had novel (R157S in arnT and Q319R in eptA) and rare mutations (V39L, R152H, S260L and A279G in eptA). Several substitutions were also identified in mgrB, pmrB, phoP and phoQ genes. The mcr genes were absent in all isolates. Isolates had variants from existing classes of fosA gene. CONCLUSION: Complex combination of mutations might have led to colistin resistance, which suggests that continuous surveillance of molecular mechanisms is required.

Antimicrobial resistance in beta-haemolytic streptococci in India: A four-year study.

BACKGROUND & OBJECTIVES: The incidence and severity of invasive and non-invasive infections demonstrate variability over time. The emerging resistance of Group A streptococci (GAS) to commonly used antibiotics is of grave concern. This study was conducted to assess the antimicrobial resistance of beta-haemolytic streptococci (ßHS) in India and to ascertain the molecular mechanisms of resistance. METHODS: All isolates of ßHS from the Trauma Centre of All India Institute of Medical Sciences (AIIMS) (north India), and heavily populated area of old Delhi from 2010 to 2014 and Yashoda Hospital, Secunderabad (in south India, 2010-2012) and preserved isolates of ßHS at AIIMS (2005-2009) were included. Phenotypic confirmation was done using conventional methods and the Vitek 2. Antibiotic sensitivity testing was done by disc diffusion and E-test. Detection of resistance genes, erm(A), erm(B), mef(A), tet(M) and tet(O), was done by polymerase chain reaction (PCR). RESULTS: A total of 296 isolates of ßHS (240 from north and 21 from south India) were included in the study. Of the 296 ßHS, 220 (74%) were GAS, 52 (17.5%) were Group G streptococci and 11 (3.7%), 10 (3.3%) and three (1%) were Group B streptococci, Group C streptococci and Group F streptococci, respectively. A total of 102 (46%) and 174 (79%) isolates were resistant to tetracycline and erythromycin, respectively; a lower resistance to ciprofloxacin (21, 9.5%) was observed. A total of 42 (14%) and 30 (10%) isolates, respectively, were positive for tet(M) and erm(B) genes. Only 13 (5%) isolates were positive for mef(A). None of the isolates were positive for erm(A) and tet(O). There was discordance between the results of E-test and PCR for erythromycin and tetracycline. INTERPRETATION & CONCLUSIONS: A high level of resistance to erythromycin and tetracycline was seen in ßHS in India. Discordance between genotypic and phenotypic results was reported. Absence of erm(A) and tet(O) with high prevalence of tet(M) and erm(B) was observed.
