CT-based generation of synthetic-pseudo MR images with different weightings for human knee.

Synthetic MR images are generated for their high soft-tissue contrast avoiding the discomfort by the long acquisition time and placing claustrophobic patients in the MR scanner's confined space. The aim of this study is to generate synthetic pseudo-MR images from a real CT image for the knee region in vivo. 19 healthy subjects were scanned for model training, while 13 other healthy subjects were imaged for testing. The approach used in this work is novel such that the registration was performed between the MR and CT images, and the femur bone, patella, and the surrounding soft tissue were segmented on the CT image. The tissue type was mapped to its corresponding mean and standard deviation values of the CT# of a window moving on each pixel in the reconstructed CT images, which enabled the remapping of the tissue to its MRI intrinsic parameters: T1, T2, and proton density (ρ). To generate the synthetic MR image of a knee slice, a classic spin-echo sequence was simulated using proper intrinsic and contrast parameters. Results showed that the synthetic MR images were comparable to the real images acquired with the same TE and TR values, and the average slope between them (for all knee segments) was 0.98, while the average percentage root mean square difference (PRD) was 25.7%. In conclusion, this study has shown the feasibility and validity of accurately generating synthetic MR images of the knee region in vivo with different weightings from a single real CT image.

MicroRNA profiling in dogs undergoing induced ischemic heart infarction: An experimental study.

Background and Aim: MicroRNAs (miRNAs) play an important role in various biological functions. According to many studies, miRNA expression is tissue-specific, strongly controlled throughout embryogenesis, and over- or under-expressed in numerous disorders, including cardiovascular pathologies. This study aimed to screen, characterize, and profile many induced biomarkers (miRNAs) in dog serum before and after experimentally inducing a regional myocardial infarction (MI) by occluding the coronary arteries under general anesthesia. Materials and Methods: A preclinical experimental animal study recruited 12 healthy canine dogs. The selected canine dogs were anesthetized with 1 mg/kg xylazine and 15 mg/kg ketamine before undergoing femoral arterial catheterization under fluoroscopic supervision. Commercial assay kits were used to purify total RNA and miRNA before the occlusion and 2 h after the occlusion according to the manufacturer's guidelines, and the samples were stored in RNase/DNase-free water at -80°C. Data were analyzed by GraphPad Prism 5.0 software (GraphPad Prism, San Diego, CA) SPSS, and GenEx software (www.multid.se) or (REST V3). Results: Among 325 transcribed genes, 20 were identified in 2 h. After MI, 14 biomarkers were negative, indicating downregulation, and 6 (3-F08, 3-B10, 4-A11, 1-A06, 2-E01, 3-F10) were positive, indicating upregulation. Polymerase chain reaction assay results showed a normalized fold-change in gene expression in the test sample. Fold values >1 represented a biologically significant change. Conclusion: Profiling of miRNAs before and after MI in a dog model revealed upregulation of six previously unidentified biomarkers (3-F08, 3-B10, 4-A11, 1-A06, 2-E01, and 3-F10), indicating various miRNA regulatory patterns.

Knee Pain and Limping as Presenting Symptoms of Metastatic Thyroid Cancer.

BACKGROUND Most thyroid nodules are fortunately benign; however, up to 15% of thyroid nodules turn out to be malignant. Follicular thyroid cancer is the second most common type of thyroid malignancy, originating from the follicular cells lined by cuboidal epithelium, with a peak incidence between the ages of 40 and 60 years. The feature that differentiates follicular carcinoma from adenoma is the presence of capsular invasion. While distant metastases occur in 10% to 15% of patients with follicular thyroid cancer, only 2% to 13% of patients with thyroid cancer develop bone metastases. Metastasis to the knee in thyroid cancer is extremely rare. This report describes a rare case of limping and knee pain as presenting symptoms of metastasis of follicular thyroid cancer to the knee joint observed during clinical practice and addresses its implications. CASE REPORT A 60-year-old woman presented with right knee swelling, disabling pain, and difficulty with walking in the last 3 months. Magnetic resonance imaging showed a large mass, and a computed tomography scan-guided biopsy confirmed it to be a distant metastasis of follicular thyroid cancer. The patient underwent total knee replacement and thyroidectomy and was postoperatively treated with radioactive iodine therapy. She was in good condition at her 1-year follow-up, with no recurring pathology. CONCLUSIONS This case reports on the metastasis of follicular thyroid cancer to the knee, which is exceedingly rare. However, it should be considered in the differential diagnoses of lytic bone lesions, as early diagnosis and management yield a more favorable prognosis for patients.

Predicting mortality and morbidity in emergency general surgery patients in a Jordanian Tertiary Medical Center: a retrospective validation study of the Emergency Surgery Score (ESS).

OBJECTIVE: The Emergency Surgery Score (ESS) is a predictive tool used to assess morbidity and mortality rates in patients undergoing emergent surgery. This study explores the ESS's predictive ability and reliability in the Jordanian surgical population. DESIGN: A retrospective validation study. SETTING: A tertiary hospital in Jordan. PARTICIPANTS: A database was created including patients who underwent emergent surgery in King Abdullah University Hospital from January 2017 to June 2021. PRIMARY AND SECONDARY OUTCOME MEASURES: Relevant preoperative, intraoperative and postoperative variables were retrospectively and systematically gathered, and the ESS was calculated for each patient accordingly. In addition, a multivariable logistic regression analysis was performed to assess the correlations between the ESS and postoperative mortality and morbidity along with intensive care unit (ICU) admissions. RESULTS: Out of total of 1452 patients evaluated, 1322 patients were enrolled based on inclusion and exclusion criteria. The mean age of the population was 47.9 years old. 91.9% of the patients were admitted to the surgical ward through the emergency department, while the rest were referred from inpatient and outpatient facilities. The mortality and postoperative complication rates were 3.9% and 13.5%, respectively. Mortality rates increased as the ESS score gradually increased, and the ESS was evaluated as a strong predictor with a c-statistic value of 0.842 (95% CI 0.743 to 0.896). The postoperative complication and ICU admission rate also increased with reciprocal rises in the ESS. They were also evaluated as accurate predictors with a c-statistic value of 0.724 (95% CI 0.682 to 0.765) and a c-statistic value of 0.825 (95% CI 0.784 to 0.866), respectively. CONCLUSION: The ESS is a robust, accurate predictor of postoperative mortality and morbidity of emergency general surgery patients. Furthermore, it is an all-important tool to enhance emergency general surgery practices, in terms of mitigating risk, quality of care measures and patient counselling.

Ischemic stroke demographics, clinical features and scales and their correlations: an exploratory study from Jordan.

Aims: The authors aimed to assess the ischemic stroke risk factors and scales. Materials & methods: A retrospective cohort study was conducted on patients with acute ischemic stroke (from January 2017 to December 2018). The scores of the National Institutes of Health Stroke Scale (NIHSS) at admission and discharge and of the modified Rankin Scale (mRS) and Barthel Index (BI) scale post-month of the stroke were collected. Results: Out of 376 patients, 359 were included, with a mean (standard deviation) age of 67.8 (12.2) years and male predominance (56.2%). Hyperlipidemia and hypertension were the most prevalent comorbidities (91.1% and 80.5%, respectively). The NIHSS, BI and mRS scores were worse among women, with no significant effects for comorbidities. The NIHSS scores at admission and discharge were significantly correlated with the post-month BI and mRS scores. Conclusion: The study findings suggest a complex interplay of gender, strict control and prevention of the modifiable stroke risk factors, as well as the association of neurological deficits' intensity with the functional outcomes.

Generation of Synthetic-Pseudo MR Images from Real CT Images.

This study aimed to generate synthetic MR images from real CT images. CT# mean and standard deviation of a moving window across every pixel in the reconstructed CT images were mapped to their corresponding tissue-mimicking types. Identification of the tissue enabled remapping it to its corresponding intrinsic parameters: T1, T2, and proton density (ρ). Lastly, synthetic weighted MR images of a selected slice were generated by simulating a spin-echo sequence using the intrinsic parameters and proper contrast parameters (TE and TR). Experiments were performed on a 3D multimodality abdominal phantom and on human knees at different TE and TR parameters to confirm the clinical effectiveness of the approach. Results demonstrated the validity of the approach of generating synthetic MR images at different weightings using only CT images and the three predefined mapping functions. The slope of the fitting line and percentage root-mean-square difference (PRD) between real and synthetic image vector representations were (0.73, 10%), (0.9, 18%), and (0.2, 8.7%) for T1-, T2-, and ρ-weighted images of the phantom, respectively. The slope and PRD for human knee images, on average, were 0.89% and 18.8%, respectively. The generated MR images provide valuable guidance for physicians with regard to deciding whether acquiring real MR images is crucial.

Clinical and electrocardiogram presentations of patients with high serum potassium concentrations within emergency settings: a prospective study.

BACKGROUND: Elevated potassium level is a common and reversible peri-arrest condition. Diagnosis and management of hyperkalemia in a short time is critical, where electrocardiogram (ECG) alterations might be helpful. We aimed to investigate the role of clinical features and ECGs in early diagnosing and treating hyperkalemia. METHODS: Prospectively, adult patients who presented to the emergency department (ED) from July 2019 to March 2020 with hyperkalemia (serum potassium ≥5.5mmol/L) were included. History was obtained, and laboratory investigations and ECGs were performed at the presentation and before initiating hyperkalemia therapy. Hyperkalemia severity was divided into mild (5.5-5.9mmol/L), moderate (6.0-6.4mmol/L), and severe (≥6.5mmol/L). A cardiologist and emergency physician blinded to laboratory values, study design, and patients' diagnoses interpreted ECGs and presenting symptoms independently to predict hyperkalemia. RESULTS: Sixty-seven hyperkalemic patients with a mean (±SD) serum potassium level of 6.5±0.7mmol/L were included in this study. The mean age was 63.9±15.1, and 58.2% were females. Hyperkalemia was mild in 10.4%, moderate in 40.3%, and severe in 49.3%. Almost two thirds of patients (71.6%) had hypertension, 67.2% diabetes, and 64.2% chronic kidney disease. About one-quarter of patients (22.4%) were asymptomatic, while fatigue (46.3%), dyspnea (28.4%), and nausea/vomiting (20.9%) were the most common presenting symptoms. Normal ECGs were observed in 25.4% of patients, while alterations in 74.6%. Atrial fibrillation (13.4%), peaked T wave (11.9%), widened QRS (11.9%), prolonged PR interval (10.5%), and flattening P wave (10.5%) were the most common. Peaked T wave was significantly more common in severe hyperkalemia (87.5%) than in mild and moderate hyperkalemia (12.5%, 0.0%, respectively) (p=0.041). The physicians' sensitivities for predicting hyperkalemia were 35.8% and 28.4%, improved to 51.5% and 42.4%, respectively, when limiting the analyses to severe hyperkalemia. The mean (±SD) time to initial hyperkalemia treatment was 63.8±31.5 min. Potassium levels were positively correlated with PR interval (r=0.283, p=0.038), QRS duration (r=0.361, p=0.003), peaked T wave (r=0.242, p=0.041), and serum levels of creatinine (r=0.347, p=0.004), BUN (r=0.312, p=0.008), and CK (r=0.373, p=0.039). CONCLUSIONS: The physicians' abilities to predict hyperkalemia based on ECG and symptoms were poor. ECG could not be solely relied on, and serum potassium tests should be conducted for accurate diagnosis.

Successful Use of Neurovascular Plug for Embolization of Scalp Arteriovenous Fistula: A Novel Technique.

PURPOSE: We report a case of a pediatric patient developing a delayed-onset scalp arteriovenous fistula (AVF) and pseudoaneurysm managed with a new technique. TECHNIQUE: A 10-year-old boy presented to the outpatient clinic complaining of a growing pulsatile mass in the right side of the skull after head trauma 6 months ago. He had no neurological deficits. Imaging studies revealed scalp AVF with pseudoaneurysm. The arterial feeding was from the right temporal artery, while the blood was drained into the superior sagittal sinus and the facial vein. The fistula was occluded successfully by a microvascular plug (MVP). Follow-up angiography 1 year later showed that the AVF was no longer seen with complete embolization of pseudoaneurysm, total occlusion of the abnormal vessels, and the absence of MVP migration. CONCLUSION: To the best of our knowledge, we report the first case of successfully using MVP to treat scalp AVF. The MVP is a novel technique with its unique ability to achieve rapid, safe, effective, and permanent vascular occlusion through a single device. Besides, the possibility of delayed-onset traumatic vascular injuries should be considered in a patient with head or facial trauma.

Impact of COVID-19 lockdown on the incidence and patterns of toxic exposures and poisoning in Jordan: a retrospective descriptive study.

OBJECTIVES: To describe the effect of the COVID-19 lockdown in Jordan (21 March 2020-21 May 2020) on the incidence and patterns of toxic exposures and poisoning as compared with the same period from the previous year (21 March 2019-21 May 2019). DESIGN: A retrospective descriptive study. METHODS: Call data sourced from Pharmacy One Poison Center from the lockdown period (21 March 2020-21 May 2020) and the same period during 2019 (21 March 2019-21 May 2019) were revised. In addition, a database was established and analysed. RESULTS: We noticed that not only did calls increased, but there was also a noticeable change in call patterns. Calls increased by 91% (544 vs 285 calls) during the lockdown period. Drugs were the most common among types of exposure, and the most prevalent route of exposure was ingestion. There was a notable increase in ocular exposure by 550% (13 vs 2 cases). The majority of exposures were at home and there were no occupational exposures. We found an increase in household cleaner exposure among males and an increase in alcohol exposure in females. Children aged below 5 years are the most affected. Even though there is an increase in the total number of cases, severe cases decreased. CONCLUSION: The lockdown effect on rates of toxic exposures was prominent, whether through the increase in calls or the change in patterns. As people spent more time at home, their exposure to toxic agents increased. Furthermore, cleaning recommendations led to the misuse of cleaning and disinfectant products, increasing exposures related to abating the COVID-19 infection.

Effects of Elemental Mercury Vapor Inhalation on Arterial Blood Gases, Lung Histology, and Interleukin-1 Expression in Pulmonary Tissues of Rats.

We investigated the effects of elemental mercury vapor inhalation on arterial blood gases (ABGs), lung histology, and interleukin-1 (IL-1) expression in pulmonary tissues in rats. A total of 42 Sprague Dawley rats were divided randomly into three groups. Rats in the first group were used as the control (CG). A short-term group (STG) and a long-term group (LTG) were exposed to 500 µg/m3 of mercury vapor 2 hrs/day for 21 days and 65 days, respectively. After exposure periods were completed, arterial blood samples were obtained, and ABGs were measured. Lung tissue sections were prepared for histology evaluation and immune-stained to detect IL-1 expression. There was a significant decrease in body weight in both STG (15%) and LTG (22%) compared with the CG. In the LTG, six out of 14 (43%) rats died, including two males and four females, while none of the rats in the STG died during the experiment. In both STG and LTG, a significant acid-base imbalance was characterized by a significant decrease in blood pH values and a significant increase in PCO2 values. Both PO2 and SpO2 blood values were significantly decreased in the STG and LTG, while no changes were observed in HCO3 values in all groups. Histological evaluation of lung tissues revealed severe lesions characterized by pulmonary emphysema and inflammatory cellular infiltrate. IL-1 expression in lung tissues was not significantly different between exposed rats and control subjects. These results indicate significant alterations in blood acid-base status characterized by severe respiratory acidosis with hypoxemia and no evidence of compensatory alkalosis in rats after exposure to short- and long-term elementary mercury vapor.

Expressions of heat shock protein 90, inducible nitric oxide synthase, and vascular endothelial growth factor in the skin of diabetic rats.

BACKGROUND AND AIM: Chronic skin ulceration is a common and painful condition that affects about 15% of patients with diabetes worldwide. The aim of this study was to evaluate the expressions of heat shock protein 90 (HSP 90), inducible nitric oxide synthase (iNOS), and vascular endothelial growth factor (VEGF) in the skin of diabetic rats. MATERIALS AND METHODS: A total of 20 rats were divided randomly into two equal groups. Diabetes mellitus (DM) was induced in the rats of Group 2, whereas the rats in Group 1 were kept healthy and served as control. DM was induced by a single intraperitoneal injection of alloxan monohydrate at 120 mg/kg. Rats were considered diabetic if the blood glucose level was above 200 mg/dL. After induction of DM, the rats were monitored daily for 28 days. On day 28, the rats were humanely euthanized, and full-thickness skin punch biopsy was obtained from the dorsal side of the thoracolumbar region. Indirect immunoperoxidase staining was used to evaluate the expressions of HSP 90, iNOS, and VEGF in the skin tissue specimens. RESULTS: The expressions of HSP 90, iNOS, and VEGF in the skin were significantly higher in diabetic rats than in the control rats. On day 28 in diabetic rats, a positive correlation (r=0.65, p=0.01) was detected between mean blood glucose level and the expression levels of HSP 90, iNOS, and VEGF. CONCLUSION: The results of this study indicated that DM upregulated the expressions of HSP 90, iNOS, and VEGF in the skin tissues of diabetic rats and may impact the healing of skin wounds. However, this study was preliminary and further studies to investigate this relationship are warranted.

Characterizing and Profiling microRNAs in Dogs Undergoing Induced Ischemic Brain Stroke After Middle Cerebral Artery Occlusion Under Fluoroscopic Guidance.

PURPOSE: Ischemic stroke of the brain is still considered one of the most common causes of disability and death in developed and developing countries in human beings despite advances in medicine and technology. This study was conducted to characterize and profile tens of induced biomarkers (microRNAs) after experimentally inducing regional ischemic stroke of the brain by occluding the middle cerebral artery under fluoroscopic guidance using an autologous blood clot. PATIENT AND METHODS: A total of six healthy dogs were recruited for this study. The microRNAs were profiled in the blood and urine before and after occluding the middle cerebral artery using genetic techniques. RESULTS: The very highly expressed genes were comprised within cluster A, followed by cluster D in both 24 and 48-hour brain samples. Clusters B and C revealed down-regulated genes, while miRNAs remained up-regulated in the 24-hour samples merely in cluster F. Upregulated genes at 48 hours of reperfusion were included in cluster E. On the other hand, changes were observed after a day on the cluster G genes. Exclusive upregulation was notified after 2 days due to the changes in mIR-138. The normalized gene expression in the test sample is witnessed through Fold-Change, which divides the control sample's normalized gene expression. Moreover, fold-change has emerged as a significant approach for representing fold-regulation. CONCLUSION: The microRNAs expression in blood and urine may have a potential role in the diagnosis, prognosis, and assessment of therapy associated with cerebral artery occlusion under fluoroscopic guidance.

Prevalence estimates of drug addiction among high-school students and its association with violence, and school behaviors: A cross-sectional study from Jordan.

INTRODUCTION: This study aims to estimate the prevalence of drug addiction among high-school students and its association with violence and school behavior. The present study provides baseline data focusing specifically on the extent of drug addiction and violence. METHODS: A cross-sectional study design was used. The questionnaire covered students' demographic profiles, including age, gender, and academic branch, and statements related to violent behaviors and school-related factors. A urine sample was collected from each participant to test for drugs and was analyzed by Multi-Drug Rapid Test Cup. RESULTS: Out of 440 students, a total of 414 were included in this study. Positive drug use via urine sample was confirmed in 70 students (16.9%), with 80% being males. Violent behaviors were common, including used to write on the walls (118, 28.5%), had problems with teachers (107, 25.9%) or peers (267, 64.5%), or using abusive language with school staff (63, 15.2%). There were no significant associations between drug addiction and these violent behaviors (p > 0.05). Students who had no respect for the teachers were significantly more in the addicted group (31.4%) than the non-addicted group (14%) (p = 0.004). CONCLUSION: High school should be identified as a critical period at risk for drug use and violent actions. This study points to the importance of early detection of drug addiction among vulnerable young people, enabling the development of educational programs to prevent abuse and dependence on substances.

Nondysraphic spinal intramedullary lipoma: A rare case and management.

A 14-year-old female patient presented with symptoms of chronic mid and low back pain that radiated to both lower limbs for 5 months, with rapidly progressive lower limb weakness and urine retention. Radiologic evaluation revealed an intramedullary mass at the level of first to sixth thoracic vertebrae. The patient underwent surgery and intraoperative findings showed an intramedullary mass lesion composed of well-differentiated fat tissue. A postoperative histopathologic examination revealed mature adipose tissues consistent with lipoma. Post-operatively patient showed improvement in lower limb motor power and started an extensive rehabilitation program.

The utility of brain CT scan modality in the management of dizziness at the emergency department: A retrospective single-center study.

OBJECTIVES: This study examines the usefulness of computed tomography (CT) scans in evaluating patients with dizziness in the emergency department (ED). METHODS: Medical records of patients presented with complaints of dizziness or vertigo to the ED of a tertiary university hospital and underwent head CT scans from July 2015 to June 2018 were reviewed. The patients' demographic information, presenting symptoms, and final head CT scan and Magnetic resonance imaging (MRI) results were collected. Stepwise logistic regressions were used to analyze data. RESULTS: A total of 326 dizzy patients were included in this study. The majority of the patients (83.1%) were older than 44 years. Acute vertigo pattern of dizziness was detected among 50.6% of the patients and was more common among females than males (p < 0.001). Of these 326 patients who underwent head CT scans, 49 (15%) had abnormal findings with acute ischemic stroke was the most common one. A total of 191 patients underwent follow-up studies. MRI accounted for 70% of the follow-up studies. Of the 134 patients who received MRI of the brain, 36 (27%) had abnormal findings. A significant correlation of RBCs level, presence of other symptoms, and frequency of episodes with the presence of vertigo (p < 0.001) was found. CONCLUSION: The study's findings indicate low effectiveness of head CT scan compared to MRI for dizziness management. Future studies are suggested to provide more insights into the cost-effectiveness and utility of head CT scans and MRI in providing valuable findings.

Ventriculo-femoro-caval shunt: a salvage surgery.

Ventriculo-femoral vein shunts have been described in few case reports as an alternative for treating complex cases of hydrocephalus in which other accesses are discarded. To our best knowledge, only 6 cases have been reported in the literature to date. We present a case of a 2-year-old female patient with hydrocephalus secondary to neonatal sepsis and meningitis. Patient was operated with various types of shunting procedures, such as ventriculo-peritoneal (V-P) shunt, ventriculo-atrial (V-A) shunt, ventriculo-pleural (V-PL) shunt, ventriculo-vesical shunt, ventriculo-superior sagittal sinus (V-SSS) shunt, and ventriculo-caval (V-C) shunt. All previous procedures were unsuccessful in treating the hydrocephalus. Finally, right ventriculo-femoro-caval shunt procedure was performed. Distal catheter was inserted into the right femoral vein and passed toward inferior vena cava under fluoroscopy guidance. The early postoperative period was uneventful. Late postoperative complications consisting of few periods of shunt dysfunction and distal obstruction were managed as an outpatient with injection for diluted heparin in the shunt valve, resulting in recovery of the shunt function. This was the management until the age of 4 when the femoral vein shunt was removed and right ventriculo-pleural shunt was placed. The patient tolerated this surgery and long-term follow-up showed good neurological status without episodes of shunt dysfunction.

Cranioplasty for Skull Defect With Polypropylene Abdominal Wall Mesh.

ABSTRACT: Cranioplasty is a routine procedure in the practice in neurosurgery and craniofacial surgery. For the closure of the cranial defect, it may be difficult or impossible to split the bone sufficiently to obtain enough bone for complete closure of the defect in younger children. Thus, sometimes there is the need to use allografts, which may not be widely available in rural practice. We present 2 cases of cranioplasty with widely available and used polypropylene abdominal wall mesh. To add rigidity to the construct, the mesh was organized in a multilayered fashion. Postoperative follow-up showed good functional and cosmetic results.

Castleman Disease: An Unusual Cause of an Isolated Neck Mass.

ABSTRACT: A 15-year old female patient was complaining from swelling in the left side of the neck since 3 months. Physical examination showed palpable and mobile left supraclavicular neck mass in the carotid triangle, uvula deviation to the left side and normal vocal cords position and function. Neck imagings showed well-defined, well-encapsulated left neck mass in the left carotid sheath pushing the internal jugular vein anteriorly and the common carotid artery posteriorly. The mass was extending from the level of C4 superiorly and the supraclavicular region inferiorly. Patient was operated with left anterior approach and circumferential dissection and enucleation was performed. Post-operative period was uneventful and devoid of any complications or deficits. Histopathological examination revealed Castleman disease.

Ganglioglioma of optic chiasma: A case report and review of literature.

BACKGROUND: Gangliogliomas are neoplasms containing both astrocytic and neuronal components. We present a case of gangliogliomas of the optic chiasm, which are extremely rare pathologies. CASE DESCRIPTION: A 16-year-old female patient referred to our clinic with gradual deterioration of vision for the age of 1 year mostly in the right eye. Ophthalmic examination confirmed reduced visual acuity with only perception of light in the left eye. Brain magnetic resonance imaging showed a solid mass lesion involving the hypothalamus and the optic chiasm, which was hypointense on T1-weighted images, hyperintense on T2-WI, and marked homogenous contrast enhancement. The patient was operated and bulging of the optic chiasm and the site of lamina terminalis was seen. Subtotal resection of the tumor was achieved. Histopathological examination revealed ganglioglioma (WHO Grade I). Follow-up of the patient was for 3 years and 8 months with stable neurologic and radiologic findings. CONCLUSION: To the best of our knowledge, 20 cases, including ours, have been reported in the literature and a presurgical diagnosis of ganglioglioma is very infrequent with confused radiologically with low-grade pilocytic astrocytomas.

Prevalence, Clinical Characteristics, and Risk Among Patients with Ischemic Heart Disease in the Young Jordanian Population.

PURPOSE: This study aims to evaluate the prevalence of ischemic heart disease (IHD) among the young population in Jordan. We examined the risk factors that might be involved in disease incidence. Clinical characteristics, patients' living standards, and various other risk factors were considered to conduct the study. METHODS: A retrospective study was conducted at King Abdullah University Hospital. Data were collected from patients who visited this hospital between January 2013 and December 2017. Only young Jordanian adults of age <50 years were included in this study. The data of 358 patients were purposively collected and analyzed (as per the determined inclusion criteria), where information related to their baseline characteristics, clinical characteristics, and related biochemical assays was reviewed. RESULTS: This study showed a high prevalence of IHD among young males in Jordan. It also revealed that increased age, smoking, hypertension, unfavorable lipid profile, and obesity were the major possible risk factors for the occurrence of disease. These patients were initially diagnosed with either unstable angina or acute myocardial infarction. Initial WBCs count, particularly monocytes differential, was high in about one-third of patients, besides cardiac biomarkers. CONCLUSION: The high incidence of IHD was noticed among young individuals. We suggest that more efforts should be instigated for reducing the high prevalence of IHD by adopting a healthy lifestyle, preventive attitude, and nutritious food intake.
