Predictors of medical intractability in children with epilepsy onset during the first two years of life, excluding infantile epileptic spasm syndrome.

PURPOSE: Early childhood epilepsy presents a significant challenge, with approximately 30 % of individuals experiencing treatment failure. This study aimed to identify predictors of medical intractability in children with epilepsy onset during the first two years of life, excluding infantile epileptic spasm syndrome. METHODS: A total of 323 children were retrospectively evaluated. The analyses included a review of medical records for demographic, laboratory, radiological, and electroencephalographic (EEG) findings. Children were diagnosed with drug-resistant epilepsy (DRE) according to the ILAE diagnostic criteria. Twenty-one potential prognostic predictors were examined in relation to medical intractability. RESULTS: Among the 323 children (56.7 % male), 119 (36.8 %) had unknown epilepsy, 131 (40.6 %) had structural epilepsy, 53 (16.4 %) had genetic epilepsy, and 20 (6.2 %) had metabolic epilepsy. Over a median follow-up of 68 months, 55.4 % of the children achieved ≥6 months of seizure freedom, 33.1 % developed DRE, and the remaining 11.5 % had rare ongoing seizures but did not meet the criteria for DRE because they were only treated with one antiseizure medication at the last follow-up. Univariate logistic regression analyses identified ten risk factors significantly associated with DRE. Multivariate logistic regression analyses revealed that the presence of developmental delay at epilepsy onset (p = 0.000; OR 7.890; 95 %CI 2.713 to 22.945), history of status epilepticus (p = 0.000; OR 8.247; 95 %CI 3.619 to 18.793), number of antiseizure medications (ASMs) at the sixth month of diagnosis (p = 0.000; OR 20.585; 95 %CI 8.993 to 47.117), and initial EEG findings (p = 0.046; OR 2.366; 95 %CI 1.015 to 5.518) were predictors of medical intractability. Nineteen (5.9 %) children died during follow-up for various reasons, including progressive neurogenetic or neurodegenerative disorders. CONCLUSION: Developmental delay at epilepsy onset, a history of status epilepticus, the use of two or more ASMs in the sixth month of diagnosis, and abnormal initial EEG findings were associated with medical intractability.

Preemptive caudal anesthesia on back pain after lumbar discectomy: a randomized and controlled study.

OBJECTIVE: In this randomized and prospective research, we aimed to relieve surgical and muscle-related pain early after lumbar disc operations with caudal preemptive analgesia. MATERIALS AND METHODS: A total of 120 patients with single-level lumbar disc herniation were included in this study. The caudal epidural injection was performed for all patients 20 min before surgery. The patients were divided into three groups. Non-steroidal anti-inflammatory drugs or tramadol use were recorded. Pre-operative and post-operative pain was interpreted through a visual analog scale. RESULTS: There was a difference between the groups in all post-operative measurements (p < 0.05), between Group 1 and Group 3, and between Group 2 and Group 3. A statistical significance has been achieved between the groups at the 1st h, 2nd h, 4th h, and 24th h (p < 0.05). The difference between the pain intensities of the patients at the 24th h and the 1st week was statistically significant in Groups 1 and 2 (p < 0.05). Evaluation of the effects of medical treatments reduced the severity of back pain and foot pain. CONCLUSION: The preemptive bupivacaine or in combination with methylprednisolone caudal injection is an effective and safe method to reduce post-operative pain and ameliorate functional capacity for the treatment of lumbar disc herniation.

OBJETIVO: En esta investigación prospectiva aleatorizada, nuestro objetivo fue aliviar el dolor quirúrgico y muscular temprano después de las operaciones de disco lumbar con analgesia preventiva caudal. MATERIALES Y MÉTODOS: en este estudio se incluyeron un total de 120 pacientes con hernia de disco lumbar de un solo nivel. La inyección epidural caudal se realizó para todos los pacientes 20 minutos antes de la cirugía. Los pacientes fueron divididos en tres grupos. Se registró el uso de AINE o tramadol. El dolor preoperatorio y postoperatorio se interpretó a través de una escala analógica visual. RESULTADOS: Hubo diferencia entre los grupos en todas las medidas postoperatorias (p < 0.05), entre el grupo 1 y el grupo 3, y entre el grupo 2 y el grupo 3. Se ha logrado una significación estadística entre los grupos a la 1a hora, 2a hora, 4 y 24 horas (p < 0.05). La diferencia entre las intensidades de dolor de los pacientes a la hora 24 y la primera semana fue estadísticamente significativa en los Grupos 1 y 2 (p < 0.05). La evaluación de los efectos de los tratamientos médicos redujo la gravedad del dolor de espalda y de pie. CONCLUSIÓN: La bupivacaína preventiva, o en combinación con la inyección caudal de metilprednisolona, es un método eficaz y seguro para reducir el dolor posoperatorio y mejorar la capacidad funcional para el tratamiento de la hernia de disco lumbar.

Anteroposterior Combined Surgery of a Rare Massive Epithelioid Hemangioendothelioma at the Cervicothoracic Junction.

Epithelioid hemangioendothelioma is a rare mesenchymal tumor of vascular endothelial origin. Non-soft tissue epithelioid hemangioendothelioma can also be seen in different organs. Although chemotherapy has been used in some patients, complete surgical removal of the tumor tissue has proven to be the most durable solution. A 15-year-old female patient was admitted to our institution with right arm and neck pain. The patient complained of numbness and weakness in the right hand. Computerized tomography indicated an expansile lesion exhibiting osteolytic features located predominantly on the right side of the corpus, pedicle, lamina, and lateral processes of the C7-T1 vertebra. The patient underwent a surgical procedure involving the application of a bilateral C4-5-6 lateral mass screw, left C7-T1 pedicle screw, and bilateral T2-3 pedicle screw and fusion. The complete residual neoplasm was surgically removed during the procedure. Due to the rarity of epithelioid hemangioendothelioma, the existing literature on this topic is confined to case reports, supplemented by a small number of retrospective descriptive case series that aimed to improve our understanding of the clinical, pathological, and molecular features of the condition, as well as to guide potential treatment strategies.

The use of vancomycin powder in the compound depressed skull fractures.

BACKGROUND/AIM: Compound or open depressed fractures (CDF) is one of the urgent operations of neurosurgery, as it can result in complications of infection. This study is reported to investigate the effect of topical vancomycin powder to the infection rates in the compound depressed skull fractures which have been operated on. MATERIALS AND METHODS: This present study was conducted on 46 cases with compound depressed skull fractures which have been operated on. Cases were divided into two groups according to the use of subgaleal topical vancomycin powder during the operation. The preoperative and postoperative CRP levels, localization of the fracture, hospitalization time, operation length, dural injury, pneumocephalus, and mortality rates have been examined. RESULTS: In cases with dural injury and pneumocephalus, a statistically significant relationship was found between the use of topical vancomycin powder and the frequency of post-op infection (p < 0.001). It was observed that the incidence of postoperative infection was significantly higher in 12 (85.7%) cases with pneumocephalus and dural injury when vancomycin powder was not used. Also, it was observed that the post-operative infection level was significantly higher in fractures in the frontal and parietal regions without vancomycin powder(p < 0.05). CONCLUSIONS: The use of subgaleal topical vancomycin powder is an option to reduce the infection rates and mortality, especially in the cases of compound depressed fractures, which is considered as a dirty wound and prone to infection. It is especially recommended in the presence of dural injury and pneumocephalus.

Treatment method selection for sleep quality due to lumbar DISC herniation: Early surgery or others?; A single center clinical trial.

BACKGROUND/AIM: Sleep deprivation may lead to individual and social insufficiency associated with many physiological and psychological pathologies. This study is reported to investigate sleep quality and the relationship between treatment modalities of lumbar disc herniation, which is the most common cause of chronic lower back pain and sciatica. MATERIALS AND METHODS: This present study was conducted on 249 cases with chronic lower back pain and sciatica caused by a single- level lumbar disc herniation diagnosed after lumbar MRI (Magnetic Resonance Imaging) between June 2017 and September 2019. Cases were divided into three groups according to the treatment modalities: early surgical treatment (n:80), extended conservative treatment (n:142), and medical treatment only (n:27). VAS (Visual Analog Scale) and PSQI (Pittsburgh Sleep Quality Index) data before the treatment and 6 months after the treatment were statistically analyzed. RESULTS: It was determined that post-treatment VAS and PSQI scores were significantly reduced in all cases, regardless of the differences in treatment modalities (p < 0.05). In the early surgical treatment group, VAS score was improved by 69% and PSQI score was improved by 63.8%. These values were 28.5% and 38.6% in the extended conservative treatment. However, VAS score was increased by 27% in the patients who received only medical treatment. Statistical analysis of the treatment modalities showed that early surgical treatment was superior to the other treatment modalities (p < 0.05). CONCLUSIONS: It was determined that early surgical treatment of lumbar disc herniation was superior to other treatment methods in terms of maintaining the sleep quality impairments associated with deterioration in sleep quality.

Hemorrhagic Skull Base Chordoma Presenting As Chordoma Apoplexy.

Intratumoral hemorrhage/apoplexy in clival chordomas is extremely uncommon, with only 16 reported cases. The average age of patients was 46.2 years and slightly more than half were men. In cases published before 1990, all patients died from their disease without any intervention. Since then, 11 patients have undergone resection by a variety of approaches and there have been no deaths. The diagnosis of skull base chordomas relies on a combination of clinical presentation and radiographic features related to the location and invasion of the tumor. Chordomas presenting with sudden-onset symptoms should alarm the surgeon of a possible hemorrhage. As an illustration of this presentation, we describe a 58-year-old woman who presented with acute-onset headache and cranial nerve deficits. Computed tomography and magnetic resonance imaging demonstrated a hemorrhagic clival lesion with cavernous sinus extension. The patient underwent transsphenoidal resection of the lesion that resulted in the resolution of her symptoms. Histopathological evaluation of the lesion was consistent with chordoma with acute hemorrhagic components. Although intratumoral hemorrhage is rarely detected in chordomas, it should be considered a differential diagnosis of such lesions because prompt recognition and treatment are critical for patient survival.

Late recovery of stereotactic radiosurgery induced perilesional edema of an arteriovenous malformation after bevacizumab treatment.

MATERIALS AND METHODS: We present a 41-year old male patient who was admitted to our clinic with epileptic seizures, headaches and hemiparesis 14 months after SRS treatment for a left fronto-parietal Spetzler-Martin Grade III arteriovenous malformation (AVM). On his first-year follow-up perilesional edema was observed for which the patient received steroid treatment, but the patient did not show any benefit from it. In the cases of steroid resistant perilesional edemas, bevacizumab can be used for reducing symptoms and even radiological perilesional edema as well. RESULTS: In our case, we have seen the effect of bevacizumab for symptomatic perilesional edema in a AVM patient after SRS treatment after radiological / neurological recovery. Our patient's headaches decreased rapidly after 2 days after treatment and was able to mobilize himself after 2 months but total resolution of symptoms and radiological findings observed after 1,5 years. CONCLUSIONS: The duration and optimum dose of bevacizumab therapy needed to further investigation. Our study showed that bevacizumab was a long-term and effective treatment option for the cases with peritumoral edema resistant to glucocorticoid treatment, where the patient had conditions such as severe headache and neurological deficits.

Internal Auditory Canal Lipoma: An Unusual Intracranial Lesion.

BACKGROUND: Internal auditory canal (IAC) lipomas are rare intracranial lesions. Consequently, preoperative imaging is essential in differentiating IAC lipomas from more common tumors such as vestibular schwannomas. The hallmark of lipomas on magnetic resonance imaging (MRI) is hyperintensity on T1-weighted images that suppresses on fat-suppressed sequences and does not enhance with gadolinium administration. CASE DESCRIPTION: The present case describes a 53-year-old woman who was misdiagnosed with a vestibular schwannoma because of the lack of appropriate MRI sequences. CONCLUSIONS: This case demonstrates the importance of ensuring that both fat-suppressed and non-fat-suppressed T1-weighted pregadolinium images are obtained in the diagnostic process of IAC lesions. It is therefore recommended that imaging centers ensure that such sequences are included in their MRI protocols.

Giant Calvarial Ewing's Sarcoma: A Case Report.

Ewing's sarcoma (EWS) is the second most common primary bone tumor seen in children and adolescents, first being osteosarcoma. Skull lesions are seen in 6 to 9% of cases. The tumor tends to reside most frequently on frontal and parietal bones. In the literature, majority of papers on calvarial EWS present cases with intracranial involvement; extracranial extension is reported in only eight cases. The case that we are presenting in this report is a 23-year-old male patient with multiple infiltrations in femur, costal bones, and calvarium which had been diagnosed radiologically and histopathologically as EWS. The calvarial metastasis had reached a very huge size with dimensions of approximately 7.5 × 7.5 × 9.5 cm and was successfully excised totally. Twelve months of follow-up revealed no recurrence in the surgical site showing that total removal of giant cranial EWS may improve morbidity of these patients.
