ABSTRACT

PURPOSE: The aim of this study is to examine the clinical and imaging manifestations of methanol toxicity during the COVID-19 pandemic, as well as to review existing studies on this topic. The most common cause of methanol intoxication is methanol-adulterated liquor. The primary metabolite of methanol, formic acid, is responsible for pathological changes. Symptoms typically present within 6-24 h of consumption and can include visual disturbances, acute neurological symptoms, and gastrointestinal issues. During the initial year of the COVID-19 pandemic, methanol poisoning cases increased significantly. METHODS: In this study, We present six different patients with methanol intoxication and their clinical and imaging features. RESULTS: In the literature review, the most common clinical presentation was loss of consciousness and obtundation and the other was vision loss. CT scan findings showed bilateral putaminal necrosis and hemorrhage in 55% of methanol toxicity patients. CONCLUSION: Methanol intoxication, causing bilateral putaminal involvement and a 50% mortality rate in intracerebral hemorrhage patients, warrants urgent toxicological analysis due to potential putaminal hemorrhage.

ABSTRACT

The ear is a very important facial feature and enhances the overall look of the face. Usually, patients with entire ear burns also have large areas of burn in their bodies. To save the patient, skin grafting to reduce the injured body surface area is prioritized and the treatment of the ears may be inevitably delayed, which results in minor to very severe cosmetic deformity. This has a deep effect on the life quality of a patient who survives a burn injury. Therefore, any step that decreases ear deformity or loss is very crucial for the patient. There are different challenging procedures for ear reconstruction which are very tedious works. In this study, for one patient, repairing gel-platelet-rich plasma-fibrin glue was applied for the treatment of a deep dermal burned ear as a novel, non-invasive, and simple approach to give a normal shape to the ear to prevent extensive morbidity during the acute phase and deformities later as a consequence of burns. No keloid is observed after treatment.

ABSTRACT

BACKGROUND: Patients with extensive left hemisphere damage frequently have ideational apraxia (IA) and transcortical sensory aphasia (TSA). Difficulty with action coordination, phonological processing, and complex motor planning may not be indicative of higher-order motor programming or higher-order complex formation. We report on the effects of IA and TSA on the visual and motor skill of stroke patients. PURPOSE: The study aims to address the question of whether IA and TSA in bilingual individuals are the results of an error of motor function alone or due to a combined motor plus and cognitive dysfunction effect. METHOD: Twelve bilingual patients (seven males, and five females) were diagnosed with IA and TSA, and are divided into two groups of six patients. Then, 12 healthy bilingual controls were evaluated for comparing with both groups. Bilingual aphasia testing (BAT) and appropriate behavioral evaluation were used to assess motor skills, including coordination, visual-motor testing, and phonological processing. RESULTS: Findings (pointing skills) show that the performance of the L1 and L2 languages are consistently significant (p < 0.001) in healthy individuals compared to the IA and TSA groups. Command skills for L1 and L2 languages were significantly higher in healthy individuals compared to IA and TSA controls (p < 0.001). Further, the orthographic skills of IA and TSA vs controls in both groups were significantly reduced (p < 0.01). Visual skills in the L1 language were significantly improved (p < 0.05) in IA and TSA patients compared to healthy controls after 2 months. Unlike orthographic skills which were improved in IA and TSA patients, languages in bilingual patients did not simultaneously improve. CONCLUSION: Dyspraxia is a condition that affects both motor and visual cognitive functions, and patients who have it often have less referred motor skills. The current dataset shows that accurate visual cognition requires both cognitive-linguistic and sensory-motor processes. Motor issues should be highlighted, and skills and functionality should be reinforced along with the significance of treatment between IA and TSA corresponding to age and education. This can be a good indicator for treating semantic disorders.

ABSTRACT

BACKGROUND: Spinal dysraphism is characterized by failure of fusion at dorsal midline structures through the embryonic developmental stages. A terminal myelocystocele consists of a skin-covered lumbosacral spina bifida and meningocele that directly continuous with the spinal subarachnoid space. OBSERVATION: A 43-year-old woman who was diagnosed at birth with myelocystocele in the lower segments of the lumbar spine. She was not operated in the early stages of life. At the 43th years of her old, during 9-months, the sac began to progressively increase in size. In our initial examination before surgery, an extremely large skin-covered myelocystocele sac was observed in the thoracolumbar with a diameter of approximately 60 * 70 * 40 cm. patient operated and sac repaired. More than 20 liter of cerebrospinal fluid drainaged from cyst during surgery. LESSONS: The mechanism of cyst enlargement is not well understood. Progressive and severe increase in size of unrepaired myelocystocele sac is possible in old ages even without cerebral hydrocephalus.

ABSTRACT

OBJECTIVE: Postoperative inflammation and infections are common complications of spinal surgery and have similar symptoms. However, postoperative infection may lead to a poor outcome and must be differentiated from postoperative inflammation. The objective of this study is determine the changing pattern of postoperative ESR and WBC counts, and investigate the effects of different variables. METHODS: A total of 61 patients who underwent spinal surgery were enrolled in this prospective study. The erythrocyte sedimentation rate (ESR) and white blood cell (WBC) counts were measured the day before surgery and on 1st, 3rd, 5th, 7th, and 14th postoperative days. RESULTS: WBC counts increased on the 1st postoperative day in comparison with the preoperative day (p<0.001), and they gradually decreased until the preoperative value was reached on the 14th postoperative day (p=0.14). The ESR also increased postoperatively, reaching a peak on the 5th postoperative day in comparison with the preoperative day (p<0.001) and gradually decreased thereafter. However, on the 14th postoperative day, the ESR was significantly greater than the preoperative value (p<0.001). In addition, a significant positive correlation was observed between ESR and age, duration of surgery, intraoperative blood loss, and duration of anesthesia. CONCLUSION: WBC count continued to rise and was the highest on the 1st postoperative day, after which it gradually decreased and attained normal values on the 14th postoperative day, while the ESR increased on the 1st postoperative day, reached the highest level in patients with and without simultaneous instrumentation on 7th and 5th postoperative days, respectively, and gradually decreased.

ABSTRACT

INTRODUCTION: Spinal hydatidosis, a zoonotic disease caused by infection with Echinococcus spp. larvae, is rare, but its treatment remains a significant medical challenge. Approximately 70% of patients with spinal hydatidosis have lesions in their liver, 0-15% have lung involvement, and only 0.5-2% have bone involvement. CASE PRESENTATION: Here we report a 38-year-old Iranian man with spinal hydatidosis, who had a history of eight times surgery in over of 26 years due to hydatid cyst in the liver, lungs, and chest wall. At the most recent admission to hospital he presented with chest pain, paraplegia, and urinary incontinence. Magnetic resonance imaging revealed thoracic spinal hydatid disease. He underwent surgery, and the hydatid cysts were completely removed. Lower extremity forces recovered dramatically and completely within 4 weeks. CONCLUSION: Spinal hydatidosis is a rare disease, but it is associated with a high degree of morbidity, mortality, and poor prognosis. Because of the infiltrative nature of hydatid disease, surgery alone is rarely curative. The current case study demonstrates the importance of a suitable surgical approach, adequate intraoperative prophylaxis to prevent cyst rupture, and prolonged complete paraplegia.

ABSTRACT

AIM: To determine the effect of Intravenous Tranexamic Acid (TXA) on traumatic intracerebral hemorrhage. MATERIAL AND METHODS: A total of 94 cases of TBI with intracerebral hemorrhage, admitted to the emergency department who did not need surgical intervention based on a primary brain spiral computed tomography (CT) scan, were randomly assigned into two groups of 47 patients. In the intervention group, intravenous TXA was administered as one gram of bolus and one gram every 6 hours for 48 hours, and in the control group, the placebo was administered in the same way. After 6, 24, and 48 hours all the cases underwent a brain CT scan. Scans were examined for the size and diameter of hematoma and the midline shift. The information regarding the level of consciousness, hematoma volume, and diameter on CT scan were recorded on arrival and 48 hours later. RESULTS: Statistical results depict that while there was no considerable difference in the demographic aspect of the two groups, the volume and diameter of hematoma and the midline shift in the first CT scans and also their level of consciousness, the diameter and volume of hematoma and also the amount of hematoma expansion in follow up are significantly different in the two groups. CONCLUSION: The present study showed that the prescription of TXA would reduce the amount of hematoma expansion in traumatic intracerebral hemorrhage, and that medication can be introduced to reduce morbidity and complications.

ABSTRACT

BACKGROUND: Intracranial capillary hemangiomas (ICHs) have a natural history and behavior that is very different from intracranial cavernous malformations. The literature is not consistent as to the best management strategy for ICHs. CASE DESCRIPTION: Our patient is a 40-day-old male infant who presented with progressive increase in head circumference and multiple cutaneous capillary and ICHs. Obstructive hydrocephalus necessitated urgent cerebrospinal fluid (CSF) diversion, but no other surgical intervention was pursued due to the high risk-to-benefit ratio. All intracranial lesions spontaneously regressed by 11 years of age, albeit at a slower speed than the cutaneous lesions, with no functional or cognitive sequelae. We conducted a comprehensive literature review and provided a summary of all reported ICH cases. CONCLUSION: Asymptomatic patients with ICHs are best approached with close follow-up and serial imaging studies as the potential for spontaneous regression is relatively high. Patients with isolated lesions or unclear diagnoses may benefit from a stereotactic biopsy, and surgical resection should be reserved for symptomatic lesions only.

ABSTRACT

Background: The asterion is located at the posterior lateral side of the skull at the junction of the parietal, temporal and occipital bones.Methods: We examined the morphology of the asterion, its association with deep vein elements, the mastoid apex and inion in 105 adult cadavas (210 hemicraniums) including 146 males and 64 females at the anatomy lab of the Legal Medicine Organization.Results: Two types of asterion were observed. Type I was found in 14.7%, and type II in 85.3% of cases. In 70% of cases, the asterion was at or above the venous sinus. The distance between the asterion and the mastoid appendage on the right side was 47.03 mm and on the left side was 46.5 mm. The distance between the asterion and the inion at the right side was 70.55 mm and on the left side was 70.2 mm.Conclusion: The asterion in 70% of cases was at or above the level of the transverse sinus. For this reason, in posterior fossa surgical approaches, the first burr hole is preferred to start in the lower parts of the asterion.

ABSTRACT

Background: Conventionalmethods of detecting Brucella spp. suffer from technical and biological complications. Besides, newly characterized species of the genus Brucella could be neglected by previously designed polymerase chain reaction (PCR) tests. Therefore, a more accurate PCR-based test seems to be imminently needed Materials and methods: Blood samples were collected from 39 patients diagnosed with brucellosis and 25 healthy controls. Multiple sequence alignments (MSA) were performed on 500 Omp2-related protein and gene sequences. Thereafter, specific primers were designed and synthesized for the regions with highest conservancy. The collected samples were assessed by PCR test. To overcome the cross-reactivity issue, PCR thermal program was optimized regarding annealing time and temperature. Results: The MSA results indicated that the N terminus region of the Omp2 protein (DNA 5' end) is associated with highest conservancy. Primers with highest specificity were designed and synthesized. A two-step PCR reaction was successfully designed and optimized. The desirable bands were observed in clinical samples with high accuracy. Conclusion: It should be pointed out that using a precisely designed primer pair would bring about early infection detection, more success to detect all natural variants and higher cost-to-efficacy ratio in comparison to other detection methods

ABSTRACT

The ventriculus terminalis (VT) is a small ependyma-lined cavity within the conus medullaris that is in direct continuity with the central canal of the spinal cord. Cystic dilatation of the ventriculus terminalis on its own is an extremely rare pathological event in adults whose pathogenesis is uncertain. VT has been described in children as a normal developmental phenomenon. These lesions are often diagnosed incidentally during imaging and are in most cases asymptomatic, especially in children. Symptomatic dilatation of VT in adults is a rare condition with 61cases being reported to date. Symptomatic dilatation of VT in children has not been reported till now. We present a 5 year-old-boy with a sphincteric and walking disorder. The patient was assessed by clinical, electrophysiological and urodynamic investigations as well as magnetic resonance imaging (MRI) of the lumbar-sacral segment with and without gadolinium enhancement. Lumbar-sacral MRI demonstrated the presence of a cystic lesion containing cerebrospinal fluid (CSF), which did not enhance after gadolinium, compatible with the diagnosis of the ventriculus terminalis dilation.The patient underwent laminectomy and the cyst wall was fenestrated with a midline myelotomy. In 6-month of follow-up, urinary problems and gait disturbance improved.
