RESUMO

Abstract The objective of the current study was to investigate the synergistic impact of -Tocopherol and -Linolenic acid (100 µM) on IVM and IVC of Nili Ravi buffalo oocytes. Oocytes were obtained from the ovaries of slaughtered buffaloes within two hours after slaughter and brought to laboratory. Buffalo cumulus oocyte complexes were placed randomly in the five experimental groups included; GROUP 1: Maturation media (MM) + 100 µM ALA (control), GROUP 2: MM + 100 µM ALA + 50M -Tocopherol, GROUP 3: MM + 100 µM ALA + 100M -Tocopherol, GROUP 4: MM + 100 µM ALA + 200 M -Tocopherol and GROUP 5: MM + 100 µM ALA + 300 M -Tocopherol under an atmosphere of 5% CO2 in air at 38.5 °C for 22-24 h. Cumulus expansion and nuclear maturation status was determined (Experiment 1). In experiment 2, oocytes were matured as in experiment 1. The matured oocytes were then fertilized in Tyrodes Albumin Lactate Pyruvate (TALP) medium for about 20 h and cultured in synthetic oviductal fluid (SOF) medium to determine effect of -Linolenic acid (100 µM) and -Tocopherol in IVM medium on IVC of presumptive zygotes. To study the effect of -Linolenic acid (100 µM) in IVM media and increasing concentration of -tocopherol in the culture media on early embryo development (Experiment 3), the presumptive zygotes were randomly distributed into the five experimental groups with increasing concentration of -tocopherol in culture media. Higher percentage of MII stage oocytes in experiment 1(65.2±2.0), embryos at morula stage in experiment 2 (30.4±1.5) and experiment 3 (22.2±2.0) were obtained. However, overall results for cumulus cell expansion, maturation of oocyte to MII stage and subsequent embryo development among treatments remain statistically similar (P > 0.05). Supplementation of -tocopherol in maturation media having -Linolenic acid and/or in embryo culture media did not further enhance in vitro maturation of oocyte or embryo production.


Resumo O objetivo do presente estudo foi investigar o impacto sinérgico do -tocoferol e do ácido -linolênico (100 µM) na MIV e CIV de oócitos de búfala Nili Ravi. Os oócitos foram obtidos dos ovários de búfalos abatidos duas horas após o abate e levados ao laboratório. Complexos de oócitos cumulus de búfalo foram colocados aleatoriamente nos cinco grupos experimentais incluídos; GRUPO 1: Meio de maturação (MM) + 100 µM ALA (controle), GRUPO 2: MM + 100 µM ALA + 50 µM -tocoferol, GRUPO 3: MM + 100 µM ALA + 100 µM -tocoferol, GRUPO 4: MM + 100 µM ALA + 200 M -tocoferol e GRUPO 5: MM + 100 µM ALA + 300 M -tocoferol sob uma atmosfera de 5% de CO2 em ar a 38,5 °C por 22-24 h. A expansão cumulus e o estado de maturação nuclear foram determinados (Experimento 1). No experimento 2, os oócitos foram maturados como no experimento 1. Os oócitos maturados foram então fertilizados em meio de Tyrode's Albumina Lactato Piruvato (TALP) por cerca de 20 h e cultivados em meio de fluido oviductal sintético (SOF) para determinar o efeito do ácido -linolênico (100 µM) e -tocoferol em meio IVM em IVC de presumíveis zigotos. Para estudar o efeito do ácido -linolênico (100 µM) em meio IVM e aumentar a concentração de -tocoferol no meio de cultura no desenvolvimento inicial do embrião (Experimento 3), os presumíveis zigotos foram distribuídos aleatoriamente nos cinco grupos experimentais com concentração crescente de -tocoferol em meios de cultura. Maior porcentagem de oócitos em estágio MII no experimento 1 (65,2 ± 2,0), embriões em estágio de mórula no experimento 2 (30,4 ± 1,5) e experimento 3 (22,2 ± 2,0) foram obtidos. No entanto, os resultados gerais para a expansão das células do cumulus, maturação do oócito para o estágio MII e desenvolvimento embrionário subsequente entre os tratamentos permanecem estatisticamente semelhantes (P> 0,05). A suplementação de -tocoferol em meios de maturação com ácido -linolênico e / ou em meios de cultura de embriões não aumentou ainda mais a maturação in vitro de oócitos ou a produção de embriões.

RESUMO

Chronic obstructive pulmonary disease (COPD) remains a major public health problem with relatively high prevalence rates worldwide (5.0-13.0%). COPD is a major cause of morbidity and mortality worldwide and results in an economic and social burden that is both substantial and increasing. The purpose of the study was to explore the relationship of biochemical alterations of serum magnesium and uric acid with frequent exacerbations, hypoxia, increase hospital stay, morbidity and mortality in patients with COPD. This cross-sectional study was carried out in the Department of Biochemistry, Mymensingh Medical College, Bangladesh from January 2021 to December 2021. Data was collected from Medicine Department of Mymensingh Medical College Hospital, Bangladesh. A total number of 120 subjects participated in this study. Out of them, 60 apparently normal healthy individuals were selected as Group I and another 60 diagnosed COPD patients were selected as Group II. The results were calculated and analyzed by using statistical package for social science (SPSS), windows package version 21.0. Serum magnesium was measured by photoelectric colorimetric method using the test kit and serum uric acid was measured by enzymatic colorimetric method using the test kit. Data were expressed in mean±SD and statistical significance of different parameter was done by Pearson's correlation co-efficient test. The mean±SD values of serum magnesium were 2.15±0.29mg/dl and 1.54±0.30mg/dl in Group I and Group II respectively. Result was statistically highly significant (p<0.001). The mean±SD values of serum uric acid were 5.43±2.05mg/dl and 6.86±1.61mg/dl in Group I and Group II respectively. Result was statistically highly significant (p<0.001). Pearson's correlation coefficient test showed that there was significant (p=0.001) negative correlation (r= -0.415) found between serum magnesium and serum uric acid in study group. In this study, the result suggested that there was significant relation between COPD exacerbations and alteration of these biochemical parameters. So, by this study we recommended that routine evaluation of these parameters is important for prevention of exacerbations, reduction of morbidity and mortality in patients with COPD.

RESUMO

MINERvA has measured the ν_{µ}-induced coherent π^{+} cross section simultaneously in hydrocarbon (CH), graphite (C), iron (Fe), and lead (Pb) targets using neutrinos from 2 to 20 GeV. The measurements exceed the predictions of the Rein-Sehgal and Berger-Sehgal PCAC based models at multi-GeV ν_{µ} energies and at produced π^{+} energies and angles, E_{π}>1 GeV and θ_{π}<10°. Measurements of the cross-section ratios of Fe and Pb relative to CH reveal the effective A scaling to increase from an approximate A^{1/3} scaling at few GeV to an A^{2/3} scaling for E_{ν}>10 GeV.

RESUMO

Neutrino-induced charged-current single π^{+} production in the Δ(1232) resonance region is of considerable interest to accelerator-based neutrino oscillation experiments. In this Letter, high statistic differential cross sections are reported for the semiexclusive reaction ν_{µ}A→µ^{-}π^{+}+ nucleon(s) on scintillator, carbon, water, iron, and lead targets recorded by MINERvA using a wideband ν_{µ} beam with ⟨E_{ν}⟩≈6 GeV. Suppression of the cross section at low Q^{2} and enhancement of low T_{π} are observed in both light and heavy nuclear targets compared with phenomenological models used in current neutrino interaction generators. The cross sections per nucleon for iron and lead compared with CH across the kinematic variables probed are 0.8 and 0.5 respectively, a scaling which is also not predicted by current generators.

RESUMO

This Letter presents the first simultaneous measurement of the quasielasticlike neutrino-nucleus cross sections on C, water, Fe, Pb, and scintillator (hydrocarbon or CH) as a function of longitudinal and transverse muon momentum. The ratio of cross sections per nucleon between Pb and CH is always above unity and has a characteristic shape as a function of transverse muon momentum that evolves slowly as a function of longitudinal muon momentum. The ratio is constant versus longitudinal momentum within uncertainties above a longitudinal momentum of 4.5 GeV/c. The cross section ratios to CH for C, water, and Fe remain roughly constant with increasing longitudinal momentum, and the ratios between water or C to CH do not have any significant deviation from unity. Both the overall cross section level and the shape for Pb and Fe as a function of transverse muon momentum are not reproduced by current neutrino event generators. These measurements provide a direct test of nuclear effects in quasielasticlike interactions, which are major contributors to long-baseline neutrino oscillation data samples.

RESUMO

Adequate knowledge about the causes of chronic kidney disease and their potential prevention can improve poor clinical outcome in chronic kidney disease (CKD) patients. The study was designed to evaluate the serum albumin and C-reactive protein (CRP) levels in hospitalized patients with Chronic Kidney Disease. This cross-sectional study was carried out in the Department of Biochemistry, Mymensingh Medical College, Mymensingh, Bangladesh with the collaboration of the Department of Nephrology, Mymensingh Medical College Hospital, Mymensingh, from January 2021 to December 2021. The subjects were selected on the basis of inclusion and exclusion criteria by purposive and convenient sampling method. A total of 110 subjects were included in this study. Among them, 55 were diagnosed CKD patients denoted as Group I and 55 were normal healthy individuals denoted as Group II. In this study, serum albumin and CRP levels were measured. All values were expressed as Mean±SD. All statistical analysis was done by using SPSS (statistical package for social science) windows package version 21.0. Statistical significance of difference between Group I and Group II were evaluated by using student's unpaired 't'-test and the significance was defined as p<0.05. Correlation was done by using Pearson's correlation coefficient test. Mean age of Group I was 52.65±4.93 and Group II was 51.15±6.32 (p=0.165). The mean±SD of BMI was 24.46±1.84 for Group I and 24.50±1.05 for Group II (p=0.886). The mean±SD values of serum albumin were 3.62±0.26g/dl and 4.16±0.69g/dl in Group I and Group II respectively. We found highly significant (p<0.001) decrease in serum albumin. The mean±SD values of CRP were 24.00±16.73mg/L and <6.0±0.00mg/L in Group I and Group II respectively. So, we found significant (p<0.05) increase in CRP levels. There was negative correlation between serum albumin and CRP. Analyzing the findings of this study, significant decrease in serum albumin and significant increase in CRP levels were observed in CKD patients.

RESUMO

Scattering of high energy particles from nucleons probes their structure, as was done in the experiments that established the non-zero size of the proton using electron beams1. The use of charged leptons as scattering probes enables measuring the distribution of electric charges, which is encoded in the vector form factors of the nucleon2. Scattering weakly interacting neutrinos gives the opportunity to measure both vector and axial vector form factors of the nucleon, providing an additional, complementary probe of their structure. The nucleon transition axial form factor, FA, can be measured from neutrino scattering from free nucleons, νµn → µ-p and [Formula: see text], as a function of the negative four-momentum transfer squared (Q2). Up to now, FA(Q2) has been extracted from the bound nucleons in neutrino-deuterium scattering3-9, which requires uncertain nuclear corrections10. Here we report the first high-statistics measurement, to our knowledge, of the [Formula: see text] cross-section from the hydrogen atom, using the plastic scintillator target of the MINERvA11 experiment, extracting FA from free proton targets and measuring the nucleon axial charge radius, rA, to be 0.73 ± 0.17 fm. The antineutrino-hydrogen scattering presented here can access the axial form factor without the need for nuclear theory corrections, and enables direct comparisons with the increasingly precise lattice quantum chromodynamics computations12-15. Finally, the tools developed for this analysis and the result presented are substantial advancements in our capabilities to understand the nucleon structure in the weak sector, and also help the current and future neutrino oscillation experiments16-20 to better constrain neutrino interaction models.

RESUMO

Acute coronary syndrome is a growing public health concern. Diabetic patients are more vulnerable to develop acute coronary syndrome due to accelerated atherosclerosis. Acute coronary syndrome is common in diabetes mellitus and is a major cause of mortality and morbidity in these patients. Troponin-I is a biochemical marker for cardiac muscle injury. Elevated glycated hemoglobin (HbA1c) is also regarded as an independent risk factor for acute coronary syndrome in patients with diabetes mellitus.The aim of this study was to assess the relationship of HbA1c and Troponin-I level in patients with acute coronary syndrome. This cross-sectional study was conducted in the Department of Biochemistry, Dhaka Medical College, Dhaka, Bangladesh from July 2018 to June 2019. Total study subjects were ninety five of both gender selected from the admitted patients of the cardiology department of the National Institute of Cardiovascular Diseases (NICVD), Dhaka. Diagnosis of acute coronary syndrome was confirmed by cardiologist. Diagnosis of diabetes mellitus was confirmed by Random Blood Glucose (RBG) level. Study subjects were grouped, acute coronary syndrome with diabetes mellitus as Group A and acute coronary syndrome without diabetes mellitus as Group B. Baseline parameters was recorded in data collection sheet. HbA1c, Troponin-I level of all study subjects were analyzed and recorded. Mean age of the study subjects in Group A and Group B were 51.06 years and 51.66 years respectively. Male gender was predominant in both groups. Mean SBP and DBP were significantly higher in Group A than Group B. Mean HbA1c level of the study subjects in Group A was significantly higher than Group B (p=0.001). Mean Troponin-I level in Group A was also significantly higher than Group B (p=0.023). HbA1c and Troponin-I levels were positively correlated in Group A (r=0.471, p=0.001). The present study demonstrated significant positive correlation of HbA1c and Troponin-I level in diabetic patients with acute coronary syndrome.

RESUMO

Acute myocardial infarction (AMI) commonly known as heart attack is defined pathologically as the irreversible death of myocardial cells caused by ischemia. Risk factors include high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol and excessive alcohol intake. The major cause of acute MI is coronary atherosclerosis with superimposed luminal thrombus, which accounts for more than 80% of all infarcts. Micronutrients and trace elements are very essential for normal functioning of the body. Even though they are required in very small amount, an alteration in the level of this element may lead to serious diseases like CAD and its consequences. The injury induced by reperfusion of the ischemic myocardium could result partially from the cytotoxic effects of oxygen free radicals. Copper is involved in several of the reactions in the protection from free radical damage. So, this study was designed to evaluate serum cupper level in AMI patients. This case-control study was conducted in the Department of Biochemistry, Mymensingh Medical College, Mymensingh, Bangladesh from July 2016 to June 2017. Total number of subjects was 120 in number. Among them 60 were diagnosed case of acute myocardial infarction and 60 were apparently healthy volunteers. Data were collected using pre-designed data collection sheets. After proper counseling informed written consent was taken from the study population. The study revealed that mean serum copper level was higher in case group as compared to control group. The mean±SD values of copper were 105.44±24.15µg/dl and 146.49±23.52µg/dl in control and case group respectively. The level of significance was 0.001 (p<0.05). After analyzing the results of the study it is concluded that serum copper level was significantly higher in Acute Myocardial Infarction patients than normal individuals. Therefore, estimation of serum copper level in AMI patients might be useful to take appropriate measure to prevent free radical induced reperfusion injury.

RESUMO

Encephalitis is commonly caused by viruses. But beyond viruses there are so many causes of encephalitis. Encephalitis is the inflammation of the brain parenchyma due to any reason. As there are so many causes of encephalitis presentations are also variable. So to diagnose encephalitis a set of clinical, laboratory, electroencephalographic and neuroimaging criteria is used. Any children attend medical facility with sudden onset altered mental status along with any of the following features like fever, seizure, focal neurological signs should be evaluated as encephalitis. Viruses are the common cause of encephalitis. Along with infectious etiologies a vast group of noninfectious like autoimmune causes encephalitis also established. When children presented with above mentioned features along with behavior problem and or movement disorder there is a high suspicion of autoimmune etiology. Any suspected case of encephalitis should initiated treatment with antiviral along with supportive treatment; then step wise evaluation should be done to reach an etiological diagnosis. If infectious etiology could not be established or no significant improvement is found with antiviral therapy; immunomodulating therapy should be considered along. In all cases CSF analysis including biochemistry, cytology, viral PCR along with MRI and EEG should do; further investigations depend upon initial reports and clinical and epidemiological background. Dose and duration of antiviral depends on patient's age and response to treatment and comorbidity. Acyclovir 500mg/m²/BSA per dose 3 times daily for 21 days are adequate for HSV encephalitis. Monitoring of renal function is the essential. Adjuvant treatment with steroid and or manitol for cerebral edema and antiseizure drugs for convulsion is used where necessary. Meticulous fluid and nutritional support as well good general care improve outcome. In spite of adequate treatment of encephalitis mortality and morbidity was found a significant number of cases; among the morbidity behavior problem, seizure focal deficit are common.

RESUMO

Neutrino charged-current quasielastic-like scattering, a reaction category extensively used in neutrino oscillation measurements, probes nuclear effects that govern neutrino-nucleus interactions. This Letter reports the first measurement of the triple-differential cross section for ν_{µ} quasielastic-like reactions using the hydrocarbon medium of the MINERvA detector exposed to a wideband beam spanning 2≤E_{ν}≤20 GeV. The measurement maps the correlations among transverse and longitudinal muon momenta and summed proton kinetic energies, and compares them to predictions from a state-of-art simulation. Discrepancies are observed that likely reflect shortfalls with modeling of pion and nucleon intranuclear scattering and/or spectator nucleon ejection from struck nuclei. The separate determination of leptonic and hadronic variables can inform experimental approaches to neutrino-energy estimation.

RESUMO

The Coronavirus disease 2019 (COVID-19) has turned into a worldwide human tragedy and economic devastation. There had an intensive search for an effective drug against the coronavirus but not led to any breakthrough agents. Only one choice was left namely an effective and safe vaccine. Many people are ambivalent regarding corona vaccines because they also fear possible side effects from vaccination. This study was designed to track the side effects after first and second dose of the Oxford-AstraZeneca vaccines used in Mymensingh district of Bangladesh. This cross-sectional descriptive type of observational study was conducted in Mymensingh Medical College, Mymensingh, Bangladesh during the period of five months from 1 February, 2021 to 30 June, 2021 among 293 purposively selected vaccine recipients who received two doses of the Oxford-AstraZeneca vaccines. Data were collected by face to face interview of the selected vaccine recipients using a semi-structured questionnaire. Data were inputted into SPSS version 26.0. Qualitative data were summarized by percentage and quantitative data were summarized by mean and standard deviation. Necessary bivariate and multivariate analysis was done. Mean age of the respondents was 40.3 years with a standard deviation of ±8.7 years. Among the vaccine recipients female were 159(54.3%) and male were 134(45.7%). The most of the vaccine recipients were graduate and master 256(87.3%) and more than half of the vaccine recipients (156, 53.2%) were government service holder. The most of the vaccine recipients (242, 86.0%) were from urban area and 263(89.8%) vaccine recipients were non-smoker. Sixty eight (23.2%) of the vaccine recipients had different types of co-morbidities. It was found that 217(74.1%) vaccine recipients had side effects after first dose while 162(55.3%) had side effects after second dose. The difference in occurrence of side effects of first and second dose was statistically highly significant (p<0.001). Pain on the injection site was present in 172(58.7%) vaccine recipients after first dose and in 142 (48.5%) after second dose. Fever was prevalent in 98 (33.4%) after first dose and in 61 (20.8) after second dose. Headache was in 61(20.8%) and in 22(7.5%) after first and second dose respectively. Thirty one (10.6%) vaccine recipients had loose motion after first dose and 26(8.9%) had this after second dose. First dose of vaccination caused nausea in 28(9.6%) and second dose caused it in 16(5.5%) vaccine recipients. Joint pain was prevalent in 24(8.2%) after first dose and in 15(5.1%) after second dose. Rash was present in 9(3.1%) and in 3(1.0%) after first and second dose respectively. Cough was present in 5(1.7%) after first dose and in 2(0.7%) after second dose. Each 2(0.7%) had history of fainting and bodyache and 1(0.3%) reported intense weakness after first dose only. Side effects of first dose of AstraZeneca vaccine were more prevalent in female (124, 78.0%) than male (93, 69.4%). The side effects of second dose of AstraZeneca vaccine were also more prevalent in female (103, 64.8%) than male (59, 44.0%). The study results revealed that 217(74.1%) vaccine recipients had side effects after first dose while 162(55.3%) had side effects on second dose of the Oxford-AstraZeneca vaccine. Commonly experienced side effects were pain in the injection site, fever, headache, diarrhoea and joint pain. Most of the people tolerated these side effects and did not use any medicine.

RESUMO

The objective of the current study was to investigate the synergistic impact of α-Tocopherol and α-Linolenic acid (100 µM) on IVM and IVC of Nili Ravi buffalo oocytes. Oocytes were obtained from the ovaries of slaughtered buffaloes within two hours after slaughter and brought to laboratory. Buffalo cumulus oocyte complexes were placed randomly in the five experimental groups included; GROUP 1: Maturation media (MM) + 100 µM ALA (control), GROUP 2: MM + 100 µM ALA + 50µM α-Tocopherol, GROUP 3: MM + 100 µM ALA + 100µM α-Tocopherol, GROUP 4: MM + 100 µM ALA + 200 µM α-Tocopherol and GROUP 5: MM + 100 µM ALA + 300 µM α-Tocopherol under an atmosphere of 5% CO2 in air at 38.5 °C for 22-24 h. Cumulus expansion and nuclear maturation status was determined (Experiment 1). In experiment 2, oocytes were matured as in experiment 1. The matured oocytes were then fertilized in Tyrode's Albumin Lactate Pyruvate (TALP) medium for about 20 h and cultured in synthetic oviductal fluid (SOF) medium to determine effect of α-Linolenic acid (100 µM) and α-Tocopherol in IVM medium on IVC of presumptive zygotes. To study the effect of α-Linolenic acid (100 µM) in IVM media and increasing concentration of α-tocopherol in the culture media on early embryo development (Experiment 3), the presumptive zygotes were randomly distributed into the five experimental groups with increasing concentration of α-tocopherol in culture media. Higher percentage of MII stage oocytes in experiment 1(65.2±2.0), embryos at morula stage in experiment 2 (30.4±1.5) and experiment 3 (22.2±2.0) were obtained. However, overall results for cumulus cell expansion, maturation of oocyte to MII stage and subsequent embryo development among treatments remain statistically similar (P > 0.05). Supplementation of α-tocopherol in maturation media having α-Linolenic acid and/or in embryo culture media did not further enhance in vitro maturation of oocyte or embryo production.

RESUMO

Uterine leiomyoma is a common gynecological problem throughout the world. As 50% hysterectomies in black and 40% in Australians are performed due to fibroid, in our country also it is assumed that about 40%-50% hysterectomies are done due to fibroid uterus. Thus leiomyoma constitute a major public health cost to the community in terms of outpatient attendance and hospital cost for surgery. This is a descriptive type of cross sectional study among 50 patients having leiomyoma of uterus in the department of Obs and Gynae, BSMMU hospital from March 2011 to August 2011. The objective of the study is to find out the risk associated with leiomyoma, to find out the common presenting features of uterine leiomyoma and to find out best options for management. Study results showed that 62% patients were in the age group 36-45 years, 48%patients were in para1-2 group, 32% patients used combined oral contraceptive pill for contraception. Sixty percent (60%) patients presented with progressive menorrhagia and palpable mass was found in 62% cases. About 46% patients had associated medical conditions like hypertension, diabetes, obesity. Total abdominal hysterectomy was done in 32% cases. TAH with unilateral or bilateral salpingoophorectomy was done in 40% cases. Myomectomy was done in 20% cases. There is a scope for large scale study about risk factors of uterine leiomyoma like obesity, diabetes mellitus, hypertension, use of hormonal contraceptive, racial differences, different treatment modalities etc. Treatment should be individualized. However in this connection a good referral system and good communication has got a tremendous contribution in the proper management of such problems.

RESUMO

Congenital CMV infection is the most common mother to child infection having spectrum of clinical presentation which can lead to severe neurological sequelae. Early assessment of disease severity from clinical and neuroimage profile is essential to initiate proper treatment and to predict the outcome is crucial. This cross sectional observational study was conducted at Dhaka Medical College Hospital a tertiary care centre of Bangladesh from January 2019 to June 2020 in the department of pediatrics. This study was carried on among 123 infants of aged 0-12 months with polymerase chain reaction proven congenital cytomegalovirus infection over a period of 18 months. Mean age of our study group is 7.01±2.02 months, with male predominance (85.00%); majority of our infants came from lower socioeconomic background of rural area. Only 5.70% took more than two antenatal visits, 70.00% had history of perinatal asphyxia where 54.50% developed neonatal seizure. Microcephaly was present among 69.10% children, epilepsy, movement disorder, central visual impairment, different level of hearing impairment (78.90%) and severe psychomotor retardation (83.80% - 87.80%) was the most consistent initial presentation of our study group. Neuroimage abnormality was present among 94.30% of infants where cortical atrophy (86.20%) and intracranial calcification (55.30%) was the most common findings, different type of congenital malformations was also observed among the study group. Multiple logistic regression analysis showed significant value for abnormal neuroimage findings as a predictor of severity of psychomotor retardation. Congenital cytomegalovirus infection is one of the leading cause of hearing impairment and psychomotor retardation, where neuroimage findings could guide to predict the severity of psychomotor retardation.
