Jejunal angiodysplasia: surgery can be life-saving - a case report.

Introduction: Angiodysplasia, a rare cause of gastrointestinal (GI) bleeding, presents a spectrum of clinical manifestations from anemia to life-threatening hemorrhage. This case study emphasizes the significance of considering intestinal vascular malformations as a differential diagnosis, especially in the context of chronic anemia and GI bleeding. Jejunal angiodysplasia, though infrequent, poses diagnostic challenges due to the hidden nature of the small bowel in the GI system. Case presentation: A 23-year-old male presented with acute hematochezia and melena, necessitating prompt intervention. Despite a normal esophagogastroduodenoscopy, colonoscopy was hindered, CT angiography could not be performed due to the patient's unstable condition, leading to a planned exploratory laparotomy. Surgical exploration revealed a mucosal vascular lesion in the jejunum, prompting resection, and anastomosis. The patient's postoperative course was uneventful, reinforcing the importance of swift diagnosis and intervention. Clinical discussion: Angiodysplasia's pathogenesis remains unclear, with hypotheses implicating vascular endothelial growth factor and submucosal changes. Challenges in management revolve around lesion localization and stabilizing hemodynamics, necessitating a multidisciplinary approach. While endoscopy is often diagnostic and therapeutic, advanced modalities such as CT angiography may be required. Literature review highlights diverse presentations and successful interventions, including embolization and surgical resection. Conclusion: Jejunal angiodysplasia demands a comprehensive diagnostic and therapeutic strategy. The presented case underscores the pivotal role of endoscopy, embolization, and surgery in managing this condition. Timely diagnosis and intervention are crucial for mitigating the impact of angiodysplasia, necessitating further research and collaborative efforts for improved management of this rare condition.

Effects of extended abstinence on cognitive functions in tramadol-dependent patients: A cohort study.

BACKGROUND: Some pieces of the literature report impaired cognitive functioning in tramadol dependence. Whether extended abstinence improves cognitive functioning or not is not well studied. AIM: We aimed to measure the change in cognitive functioning following complete abstinence among individuals with tramadol dependence. METHODS: Eighty-three male tramadol-dependent (TD) and 57 matched healthy controls participated in this study. Cognitive functions were assessed using: The Trail making test (TMT), Wechsler Memory Scale-Revised (WMS-R), and Wechsler Adult Intelligence Scale (WAIS). Patients were assessed in the first week immediately after the end of the in-patient treatment program (T1), and after six months of sustained abstinence (T2). RESULTS: At T1, the TD group showed deficits on all tested cognitive parameters (visual attention, task switching, working memory, visual memory, verbal memory, verbal knowledge, Verbal IQ, Performance IQ, and Full-Scale IQ) in comparison to the control group. At T2, significant improvements had occurred in all the tested parameters except performance IQ. The cognitive performance of the abstinent individuals at T2 was comparable to the control group for the verbal subsets of WMS-R, Verbal IQ, Performance IQ, and Full-Scale IQ. Nevertheless, it was still worse than the control group in TMT, and all other WMS subsets. CONCLUSION: tramadol dependence has negative effects on cognitive performance, which improves with extended abstinence.

Impact of duration of untreated illness in bipolar I disorder (manic episodes) on clinical outcome, socioecnomic burden in Egyptian population.

INTRODUCTION: Bipolar disorder (BD) is a serious and chronic mental illness that may result in disability. We evaluated effect of the duration of untreated of bipolar (DUB) (manic episodes) on clinical outcomes, including episode severity, residual symptoms, duration of hospitalization, and suicide attempts, and on socioeconomic status of patients. METHODS: A total of 216 participants who had bipolar I disorder (manic state) recruited from November 2017-December 2019 from an inpatient psychiatric unit. Patients divided into 2 groups based on DUB: Group A, with DUB < 4 months; and Group B, with DUB ≥4 months. All participants had evaluation for demographic and clinical features, Socioeconomic scale, Young mania rating scale (YMRS) at admission and discharge. RESULTS: Group A participants were more often male, urban residents, married, literate and educated, professionally employed. Group A had a younger age of onset, less duration of illness, less frequency of episode, less suicide attempts, less duration in hospital, high mean of socioeconomic, lower mean of YMRS at admission and discharge in compared to Group B. CONCLUSION: A longer DUB (manic episodes)was associated with negative clinical outcomes (more frequent episode, more symptoms severity, longer hospital admission, more suicide severity, more residual symptoms) and low socioeconomic state of patients with BDI (manic episodes).

Evaluation of psychiatric comorbidity in attention-deficit hyperactivity disorder with epilepsy: A case-control study.

OBJECTIVE: Attention deficit/hyperactivity disorder (ADHD) is a developmental disorder caused by structural and functional brain abnormalities as well as genetic and environmental factors. ADHD symptoms are commonly observed in individuals with epilepsy. A few studies have reported a pattern of behavioral problems in children with combined epilepsy and ADHD. We aimed to evaluate comorbid behavioral problems and mental health concerns among children with epilepsy with ADHD and without ADHD including autism spectrum disorder, anxiety, depression, somatic problems, oppositional defiant disorder, and conduct disorder. METHODS: A total of 100 children aged between 6 and 11 years were recruited and categorized into 1 of 5 groups (20 child/group): (1) epilepsy, (2) epilepsy with ADHD, (3) ADHD with electroencephalogram (EEG) changes, (4) ADHD without EEG changes, and (5) healthy control. The scales used in our study included the Childhood Autism Spectrum Test (CAST) to screen autism spectrum conditions and related social and communication conditions, Conners' Parent Rating Scale (CPRS) to assess ADHD and other comorbid behavioral and social-emotional difficulties, and Children Behavior Checklist (CBCL) to evaluate behavior problems. RESULTS: The CAST scale score showed no significant difference among the studied groups. Regarding the Conners-3 scale, the combined type of ADHD was predominant in the ADHD with EEG changes group and the ADHD with epilepsy group, while hyperactive ADHD was predominant in the ADHD without EEG changes group. The ADHD with EEG changes group and the ADHD with epilepsy group had equally high clinical rating scores for CBCL in internalizing and externalizing problems. There was a significant difference in the profile of all Diagnostic and Statistical Manual of Mental Disorders (DSM-5) scales of CBCL among the studied groups. CONCLUSION: This is the first study to use EEG in patients with ADHD in comparison with epilepsy. ADHD with epilepsy is closely related to ADHD with EEG changes regarding psychiatric comorbidity in terms of anxiety, depression, somatic problems, oppositional defiance problems, and conduct problems.

Seroprevalence of Toxoplasma gondii among patients with schizophrenia and bipolar disorder in Upper Egypt: a comparative study with a control group.

Schizophrenia and bipolar disorder are serious neuropsychiatric disorders. Studies have found a high seroprevalence of Toxoplasma gondii in psychiatric patients. This study aimed to estimate the seroprevalence of T. gondii infection among schizophrenia and bipolar disorder patients. A case-control study was conducted in Assiut University Hospitals on 53 patients with schizophrenia, 57 patients with bipolar disorder, and 50 healthy volunteers. The psychiatric patients were recruited from the psychiatry department and the controls from their relatives. Both groups were subjected to socio-demographic assessment. Neither of them was immunodeficient nor with any other psychiatric disorders. Anti-Toxoplasma IgG antibodies were detected by indirect-ELISA to find the relationship between T. gondii infection and psychiatric disorders. Data were analysed using Chi-square test. The seropositivity rate, among patients with schizophrenia (50.9%) and patients with bipolar disorders (52.6%), was significantly higher than control group (30%) (P = 0.031 and 0.018 respectively). We found no statistically significant difference among all groups regarding environmental risk factors associated with T. gondii infection, except cat contact which was higher in schizophrenia and bipolar disorder patients (P = 0.011 and 0.007 respectively). The results of our study confirm that T. gondii infection is significantly correlated with schizophrenia and bipolar disorder and significantly associated with cat contact rather than beef consumption.

Iatrogenic facial nerve exposure in cochlear implant surgery: incidence and clinical significance in the absence of intra-operative nerve monitoring.

Objectives: Iatrogenic facial nerve injury is one of the most feared complications of cochlear implantation. Intraoperative facial nerve monitoring is used as an adjunctive modality in a variety of neurotologic surgeries including cochlear implantation. With the lack of nerve monitoring, there is a theoretically higher risk of iatrogenic fallopian canal dehiscence with facial nerve exposure, particularly the mastoid portion, during cochlear implant surgery. The purpose of this study is to determine the incidence of iatrogenic exposure of the facial nerve and its relation to the incidence of post-operative facial paralysis in the absence of facial nerve monitoring. Methods: This was a retrospective study. Medical charts of 307 patients who underwent cochlear implantation without facial nerve monitoring, from 2012 to 2017 were reviewed to identify cases with a reported iatrogenic defect over the mastoid facial nerve. The incidence of post-operative facial palsy was determined and compared to the incidence with the use of intra-operative monitoring which has been reported in the literature. Results: The incidence of iatrogenic dehiscence with facial nerve exposure was 46.58%. However, the incidence of post-operative facial palsy was only 2.1% which decreased to 0.72% in cases without injury of the facial neural sheath. This was not significantly different from the 0.73% rate reported in the literature with the use of intra-operative facial monitoring (P = 0.99). Conclusion: The incidence of iatrogenic facial nerve exposure during cochlear implantation may be relatively high. However, no additional risk of post-operative facial nerve paralysis was found, provided that the integrity of the neural sheath was preserved, even with the lack of intra-operative monitoring.

Motor cortical excitability in obsessive-compulsive disorder: Transcranial magnetic stimulation study.

OBJECTIVES: Transcranial magnetic stimulation is a non-invasive method of stimulating the brain that is increasingly being used in neuropsychiatric research. Previous work has suggested that the pathophysiology of obsessive-compulsive disorder (OCD) may involve dysfunction of excitatory and/or inhibitory brain function. This study aimed to extend those findings. METHODS: The study included 45 OCD patients and 15 age- and sex-matched healthy volunteers. Clinical evaluation was conducted using the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Hamilton Anxiety Rating Scale (HAM-A), and Clinical Global Impression rating scale (CGI). Physiological measures were resting and active motor thresholds (RMT and AMT), motor evoked potential (MEP) amplitude, cortical silent period (CSP) and transcallosal inhibition (TCI) durations, short-interval intracortical inhibition (SICI), and intracortical facilitation. RESULTS: RMT and AMT were significantly lower in patients than in the control group. The mean duration of the CSP and TCI were also significantly shorter. Obsessive trait was associated with significant reduction of TCI duration compared to compulsive trait. There was significant reduction in SICI in OCD patients compared to controls. There were no significant correlations between the Y-BOCS, HAM-A and CGI scores and the cortical excitability parameters. CONCLUSION: These results provide further evidence for inhibitory deficits or increased facilitation in cortical circuits of patients with OCD.

Migraine in Assiut Governorate, Egypt: epidemiology, risk factors, comorbid conditions and predictors of change from episodic to chronic migraine.

OBJECTIVES: Headache is one of the most common complaints in medicine. Epidemiological and population-based studies reported that migraine has a variable prevalence worldwide. This study was done to estimate the prevalence of migraine across various age groups in Assiut district, Egypt. METHODS: This is a door-to-door study. It included 4700 randomly selected individuals. RESULTS: Headache was reported in 1668 subjects (35.49%), of them, 87.65% (n = 1462) had primary headaches. Migraine prevalence was 10.51% with female-to-male ratio of 2.4:1 particularly in ages of 20-40 years. The mean age of patients was 31.46 ± 13.39 years and age at onset was 24.16 ± 12.10 years. Nearly, 63.5% had frequent attacks, 65.2% of the attacks were severe enough to stop daily activities and lasted for >1 day in 32.5% of females compared to 40.7% and 14.5% for males. Chronic or daily migraine was more in females (35.3% versus 20.7% for males). Approximately, 5.6% had chronic migraine and 1.2% had daily migraine from the start, while 24.2% had transformation from episodic to chronic migraine within 6.1 ± 4.4 years. Migraine was prevalent among those with middle educational levels and labor workers. The duration of migraine attacks was found to reduce with age but the chronic/daily migraine increased with age. Hypertension, anxiety, irritable bowel syndrome, and depression were common comorbidities with migraine. CONCLUSIONS: We believe that the work done in this study is informative as it determined the actual prevalence of migraine across various age groups and the important predictors of change in the severity, duration, and frequency of migraine in our locality.

Repetitive transcranial magnetic stimulation in the treatment of obsessive-compulsive disorders: Double blind randomized clinical trial.

Repetitive transcranial magnetic stimulation (rTMS) has become widely used as a therapeutic tool in psychiatric research. The aim of this study was to evaluate the impact of different frequencies of rTMS over right dorsolateral prefrontal cortex (DLPFC) in OCD. Forty five patients with OCD participated in the study. Patients were evaluated using: Yale-Brown obsessive compulsive scale (Y-BOCS), Hamilton Anxiety Rating Scale (HAM-A), and Clinical Global Impression-Severity scale (CGI-S). They were randomly classified into three groups: 1st group received 1Hz rTMS; 2nd group received 10Hz rTMS; and 3rd group received sham stimulation all at 100% of the resting motor threshold for 10 sessions. They were followed up after the last treatment session and 3 months later. There was a significant "time"×"group" interaction for 1Hz versus Sham but not for 10Hz versus Sham. 1Hz versus 10Hz groups showed a significant interaction for Y-BOCS and HAM-A (P=0.001 and 0.0001 respectively). 1Hz rTMS has a greater clinical benefit than 10Hz or Sham. There was also a significantly larger percentage change in GCI-S in the 1Hz group versus either 10Hz or sham. We conclude that 1Hz-rTMS, targeting right DLPFC is a promising tool for treatment of OCD.
