ABSTRACT

Introduction and importance: The herpes simplex virus (HSV) is the most common cause of acute sporadic encephalitis, a severe and often fatal disease in humans. It is associated with high mortality and morbidity rates in untreated patients. Case presentation: An 11-month-old child was admitted to the hospital presenting with acute fever and seizures characterized by staring episodes and spastic movements affecting the left side of the body. Diagnostic workup revealed abnormal T2 flair hyperintense foci in bi-temporoparietal lobes and right thalamus, and bilateral otomastoiditis were detected. A positive result for HSV-1 was obtained through HSV type 1/2 polymerase chain reaction (PCR) testing, leading to a diagnosis of herpes encephalitis. Clinical discussion: While acyclovir has proven to be an effective therapeutic option, mortality and neurological sequelae continue to be reported in a notable fraction of patients. HSV encephalitis is mainly caused by two strains of the herpes simplex virus: HSV-1, more frequently observed in children and adults, and HSV-2, commonly seen in neonates and those with compromised immune systems. MRI scans often reveal that the brain lesions are localized to certain areas, although temporal involvement may not always be evident. The symptoms of herpetic encephalitis can greatly vary, making early diagnosis and treatment vital for improving patient outcomes. Conclusion: This case report highlights the clinical presentation, diagnostic challenges, and treatment strategies for HSV-1 encephalitis and underscores the importance of early recognition and prompt initiation of antiviral therapy in suspected cases of HSV-1 encephalitis.

ABSTRACT

Objectives: The present investigation has been done to study the behavioral effects of donepezil in autistic children, given that not much research has been carried out concerning using this drug for treating autism. Materials & Methods: A cross-sectional and analytic-descriptive study was done on twenty patients with autism, aged 4-17, who visited the neurology clinic of Gorgan's Taleghani Pediatric Hospital and Yasha Pediatric Autism Clinic, Iran from 2019 to 2020. Demographic information, including sex, age, father's education, mother's education ,patient's education, family status, other problems, and ethnicity, were documented using a checklist, having been filled in during interviews with the parents. Before the trial, ABC cognitive and behavioral tests were taken to determine the children's current status. After the tests, these children received a daily dose of donepezil (10mg) before sleep for three months. At the end of the three months, the cognitive and behavioral tests were taken from the children once again. In order to analyze the effects of different factors on the studied variables, including irritability, lethargy, stereotypic behavior, hyperactivity, and inappropriate speech before and after the administration of donepezil in patients, a generalized linear model and to test the effects of donepezil on the studied variables, paired t-test was used. Results: In this study, twenty patients were registered for the investigation, 12 (60%) male and eight (40%) female. Age groups 5-6 had the highest frequency, and age group 17 had the lowest. Regardingthe parents' education, the highest frequency was for bachelor's degrees, and the lowest was for less-than-high school education and master's degree. The highest frequency for the patients' education was kindergarten (60%), and then groups without education (20%) and elementary school-level education (15%). Most of the studied patients (80%) did not have other problems besides autism, and only 20% had other problems besides autism. The family status of 15% of the families was 'separated,' and ethnically, most patients (80%) were Fars, while the rest (20%) were Turkmen. None of the analyzed factors (age, sex, father's education, mother's education, patient's education, other problems, family status, and ethnicity) had a significant effect on the studied variables after the administration of donepezil. Among the studied variables prior to the administration of donepezil and among the analyzed factors, the father's education, the patient's education, other problems, and family status had only a significant effect on stereotypic behavior. The present research findings of the present research indicated that all the studied variables, including irritability, lethargy, stereotypic behavior, hyperactivity, and inappropriate speech, were significantly decreased toward the desired goal. The decreased amounts in irritability, lethargy, stereotypic behavior, hyperactivity, and inappropriate speech after the administration of donepezil were, respectively, 38%, 44%, 54%, 41%, and 54% and on average, these behaviors were reduced by 46%. Conclusion: The present investigation has shown that all the studied variables, including irritability, lethargy, stereotypic behavior, hyperactivity, and inappropriate speech, were significantly decreased towards the desired goal by 46%. This significant decrease is indicative of the effectiveness of the treatment of autism patients with donepezil, and therefore, this drug can be placed as a prominent and essential part of the medical therapy of autism.

ABSTRACT

INTRODUCTION: Brief Resolved Unexplained Events (BRUEs) are a common presentation among infants. While most of these events are benign and self-limited, guidelines published by the American Academy of Pediatrics inaccurately identify many patients as higher-risk of a serious underlying aetiology (positive predictive value 5%). Recently, new clinical prediction rules have been derived to more accurately stratify patients. This data were however geographically limited to the USA, with no large studies to date assessing the BRUE population in a different healthcare setting. The study's aim is to describe the clinical management and outcomes of infants presenting to Canadian hospitals with BRUEs and to externally validate the BRUE clinical prediction rules in identified cases. METHODS AND ANALYSIS: This is a multicentre retrospective study, conducted within the Canadian Paediatric Inpatient Research Network (PIRN). Infants (<1 year) presenting with a BRUE at one of 11 Canadian paediatric centres between 1 January 2017 and 31 December 2021 will be included. Eligible patients will be identified using diagnostic codes.The primary outcome will be the presence of a serious underlying illness. Secondary outcomes will include BRUE recurrence and length of hospital stay. We will describe the rates of hospital admissions and whether hospitalisation was associated with an earlier diagnosis or treatment. Variation across Canadian hospitals will be assessed using intraclass correlation coefficient. To validate the newly developed clinical prediction rule, measures of goodness of fit will be evaluated. For this validation, a sample size of 1182 is required to provide a power of 80% to detect patients with a serious underlying illness with a significance level of 5%. ETHICS AND DISSEMINATION: Ethics approval has been granted by the UBC Children's and Women's Research Board (H21-02357). The results of this study will be disseminated as peer-reviewed manuscripts and presentations at national and international conferences.

ABSTRACT

AIM: The aim of this study was to analyze the Clostridium difficile and their toxins in cancerous tissues in comparison to their adjacent healthy tissues in patients with colorectal cancer (CRC) in Iran. BACKGROUND: Intestinal infection or colonization by microbial pathogens and their released metabolites may have a role in the exacerbation of CRC. METHODS: A total of 60 biopsy samples from 30 cancerous and 30 adjacent healthy tissues were collected from patients with CRC. Biopsies were homogenized and cultured in cycloserine cefoxitin fructose agar-agar medium to investigate the presence of C. difficile. DNA was extracted, PCR was performed on pure colonies for bacteria detection, and toxin genes were evaluated in each bacterium positive cases. Real-time PCR was performed on extracted DNA for quantitative comparison of Clostridium difficile in healthy and tumor tissues in CRC patients. RESULTS: Clostridium difficile was isolated from 18 of the cancerous tissue (60%) and 6 of their healthy adjacent tissue (20%) in the culture medium, but toxin genes were positive just in one sample in both groups. Real-time PCR showed the colonization in all samples. CONCLUSION: This study showed a higher prevalence of Clostridium difficile in cancerous lesions in comparison to healthy tissues. We suggest that the investigation of the rate of CD of colorectal cancer patients before surgery is critical for patients. Further studies with more samples size to study the importance of this bacterium and its toxins in the investigation of colorectal cancer patients survey is recommended.
