Introduction: Estimating the age of the ossification of the iliac crest may help determine the legal age. For this purpose, both anthropological and radiological methods (conventional radiography, ultrasound, Tomography, and MRI) have been used to study different systems. Objectives: The present study aimed to to evaluate the iliac crest apophysis for age estimation through multidetector computed tomography (MDCT) in 10- to 29-year-old individuals. Materials and Methods: This retrospective study was carried out on 10- to 29-year-old individuals who underwent pelvic CT examinations for different reasons in Imam Khomeini and Golestan hospitals of Ahwaz during 2016–2018. The CT examinations of the iliac crest apophysis of 531 patients (267 females and 264 males) were evaluated based on the Kreitner's four-stage system. Results: According to the Kreitner's four-stage system, the minimum age for both sides of the pelvis at stage 2 for girls and boys was 12 years and 13 years, respectively. However, at stage 3, the minimum age for girls and boys was 15 and 17 years, respectively. Accordingly, stage 4 was first observed in boys at age 17 on both sides of the pelvis. In contrast, it appeared in girls at the age of 20 on the right side. Conclusion: Along with the findings of other studies, the results showed that multidetector computed tomography (MDCT) is recommended for iliac crest in retrospective cases (where pelvic CT scans already exist), and it may be considered as a supportive method for age-estimation purposes. Moreover, when CT images are used along with other age estimation methods, they provide physicians with valuable supplementary information.

Background:Ultrasound (US) is a non-invasive method used for the diagnosis of urolithiasis. If the size of the stone is <5 mm, it may be difficult to diagnose. This study aimed to compare the accuracy of twinkling artifact (TA) of color Doppler US imaging with unenhanced computed tomography (CT) for detecting urolithiasis <5 mm.Materials and Methods:This prospective study was conducted on 100 patients with suspected renal calculus presented to the emergency room at the Imam Khomeini Hospital of Ahwaz in 2018. The US findings such as posterior acoustic shadowing and TA were examined for their ability to detect urinary stones (greatest diameter ≤5 mm) using CT findings as the gold standard.Results:The mean size of renal stone was 3.43 ± 0.80 mm in CT and 3.49 ± 0.82 mm in color Doppler US. There was no significant difference between CT and color Doppler US report in quantification of urolithiasis sizes (P = 0.603). TA on color Doppler US was detected in 94 (94%) patients while posterior acoustic shadow was detected in 83 (83%) patients (P = 0.004). A significant difference was found between the TA and size of stones (P = 0.036). The sensitivity, accuracy, and positive predictive values of TA for the detection of calculus were 94%, 94%, and 100%, respectively.Conclusion:The results demonstrated that TA on color Doppler US could be a good and safe alternative imaging modality with comparable results with non-contrast-enhanced computed tomography for the sensitive detection of urolithiasis <5 mm.

Seizure disease is a clinical manifestation of synchronized and elevated abnormal discharge of neurogens originally present in the cerebral cortex. This sudden abnormal cerebral stimulation is intermittent and usually short-lived and self-limiting, which lasts from a few seconds to a few minutes. In the present study, which was conducted at Ahvaz Golestan hospital, 200 children aged 2 months to 14 years old with seizure that had referred to the Magnetic Resonance Imaging (MRI) ward in 2013, were studied. Information regarding the patients was extracted during the study, included the patient's gender, age, presence of fever, cause of seizure, type of seizure, date of referral, presence of Status Epilepticus (SE), duration of hospitalization, deaths caused by the seizure, and neurological examination. According to the obtained results, it was found that out of a total of 200 selected patients, about 128 (64%) were male and 72 patients (36%) were female. The average age in male and female patients was 26.4 and 25. 5 months, respectively. The results showed that percentage of catching among males and females was 65.5% and 34.5%, respectively. Febrile seizure had the highest percentage (68.2%), which means it was of higher importance, so that among 200 selected patients, febrile seizure involved 137 patients and, as indicated, its value was much higher than other factors.

Background: Epilepsy caused by abnormal brain discharges is one of the most common neurological diseases. The main goal of imaging in epilepsy is primarily to identify underlying abnormalities, such as vascular malformations and tumors, that may have a specific treatment and, in the next grade, syndromic and etiologic diagnosis of epilepsy. In this project, the findings of computerized tomography (CT) scan of children admitted to the neurology department of Ahvaz Golestan hospital during the years 2012 and 2013 with final diagnosis of epilepsy were studied. Methods: This retrospective study was conducted on patients, who were admitted to Ahvaz Golestan hospital with a final diagnosis of epilepsy at the pediatric neurology department. By referring to the archives, all records of the patients were examined and the data were collected based on gender, age, CT scan, and abnormalities of the patients. For the descriptive analysis of data, tables and figures were used. Data analysis was performed using the SPSS 20.0. Software. Results: In this study, 85 patients with a mean age of 5.69 ± 4.05 years, the youngest of whom was one month and the oldest was 15 years old, were studied. Also, 44 of them were female and 41 were male. Among 34 patients with non-normal CT scan, 15 cases (44.1%), seven (20.6%), six (17.6%), three (8.8%), two (5.9%), and one case (2.9%) had congenital anomalies, nervous system infections, ischemichypoxic processes, neurocutaneous syndromes, neoplasm, and post-traumatic encephalopathy, respectively. Conclusions: According to this study, given that CT scans are performed only in certain cases with epilepsy and are not used to detect the cause of epilepsy, in patients with any change in duration and severity or type of epilepsy, it is required to reject other underlying causes or to expand and create possible life-threatening causes.
