Outcomes after laser interstitial thermal ablation for temporal lobe epilepsy: a systematic review and meta-analysis.

Epilepsy is a common condition that affects approximately 1% of the world's population, with about one-third being refractory epilepsy. Temporal lobe epilepsy is the most common type of drug-resistant epilepsy, and laser interstitial thermal therapy (LITT) is an innovative treatment. In this systematic review and meta-analysis, we aimed to summarize the current evidence on outcomes after LITT, including seizure freedom rate, complication rate, and neurocognitive outcome. PubMed and OVID Medline search engines were systematically searched for all indexed publications in the English language up to July15, 2023. The search was limited to human studies. Proportions and 95% confidence interval (CI) values were calculated for seizure, neurocognitive outcome, and complication rate. A total of 836 patients were included. Overall seizure outcomes, regardless of the pathology, included Engel I outcome in 56% (95% CI, 52.4-59.5%), Engel II outcome in 19.2% (95% CI, 15.4-23.6%), Engel III outcome in 17.3% (95% CI, 13.5-21.8%), and Engel IV outcome in 10.5% (95% CI 6.3-17%) of the patients. The overall decline in verbal and visual memory regardless of laterality was 24.2 (95% CI 8.6-52%) and 25.2% (8.3-55.8%). For naming, the decline was 13.4% (6.6-25.4%). The results of the pooled analysis in comparison with available data in the literature showed that seizure outcomes after LITT were slightly inferior to published data after temporal lobectomy. Data on cognitive outcomes after LITT are scarce and heterogeneous.

Hemisensory Loss after Ventriculoperitoneal Shunt Insertion.

Idiopathic intracranial hypertension includes ventriculoperitoneal shunt (VPS) insertion, with a reported complication of shunt revision in 25% of the cases 1 year after insertion. We report a case of a 28-year-old female with pituitary adenoma who developed sensory loss after VPS placement that could be explained by disruption in thalamic pathways. A lesson learned from this case is that although VPS is a simple procedure, complications can occur. Modalities can be used to detect the complications, and further revisions might be needed.

Simple approach for the histomolecular diagnosis of central nervous system gliomas based on 2021 World Health Organization Classification.

The classification of central nervous system (CNS) glioma went through a sequence of developments, between 2006 and 2021, started with only histological approach then has been aided with a major emphasis on molecular signatures in the 4th and 5th editions of the World Health Organization (WHO). The recent reformation in the 5th edition of the WHO classification has focused more on the molecularly defined entities with better characterized natural histories as well as new tumor types and subtypes in the adult and pediatric populations. These new subclassified entities have been incorporated in the 5th edition after the continuous exploration of new genomic, epigenomic and transcriptomic discovery. Indeed, the current guidelines of 2021 WHO classification of CNS tumors and European Association of Neuro-Oncology (EANO) exploited the molecular signatures in the diagnostic approach of CNS gliomas. Our current review presents a practical diagnostic approach for diffuse CNS gliomas and circumscribed astrocytomas using histomolecular criteria adopted by the recent WHO classification. We also describe the treatment strategies for these tumors based on EANO guidelines.

Pancreatic Carcinoid Tumor in a Pediatric Patient.

BACKGROUND Carcinoid tumors are well-differentiated tumors that develop from neuroendocrine cells. They are rare tumors and occur most commonly in the gastrointestinal tract, followed by the pulmonary system. They usually present with abdominal pain or cough or persistent pneumonia. They are usually diagnosed with computed tomography (CT) or magnetic resonance imaging (MRI) of the chest or abdomen. The cornerstone of treatment is surgical resection. There are rare reported cases of carcinoid tumor presenting in the pancreas as gastrinoma or insulinoma and are associated with multiple endocrine neoplasia type 1 (MEN1). CASE REPORT We report a case of an otherwise healthy 9-year-old girl who presented with manifestations of Cushing syndrome (easy fatigability, weakness, back pain, easy bruising, hirsutism, acne, skin discoloration [pigmentation], and blurred vision). She was diagnosed with incidental carcinoid tumor in the pancreas based on hypertension and typical stigmata. She underwent distal pancreatectomy and splenectomy. The histopathology showed a well-differentiated neuroendocrine tumor with G2. The diagnosis of concurrent Cushing syndrome and carcinoid syndrome can be challenging, as it is rare. It is important to screen for MEN syndrome when Cushing syndrome occurs in a child, as there is a high rate of transition to malignancy. They are usually diagnosed with ACTH, cortisol, and imaging. CONCLUSIONS Incidental hypertension in children is not common and mandates further investigation and clinical work-up to look for endocrinopathies such as Cushing syndrome and carcinoid syndrome. As the literature on such cases is scant, further reporting of cases is needed.

Epidural Abscess Following Epidural Evacuation in a Patient With Ventriculoperitoneal Shunt: A Case Report.

Epidural abscess is considered one of the most common intracranial infections. We report a pediatric patient with chronic hematopoiesis and thick double periosteal layers who developed an epidural pus collection after epidural hematoma evacuation. This article highlights the importance of detecting complications from epidural hematoma evacuation, including intracranial abscess and pus formation. Therefore, it is crucial to treat such cases meticulously.

Analysis of 190 Female Patients after Appendectomy.

This study is a retrospective cohort review carried out at a single, private tertiary center. We included 190 female patients who underwent surgery for acute appendicitis between January 2016 and December 2018. Two groups of patients were analyzed based on the pregnancy. The main outcome measures were complication rate and risk of abortion during or after surgery. Out of 190 female patients, eight of them were pregnant (4.2%). The pregnant group more significantly underwent ultrasound investigation compared to the nonpregnant group. Complicated appendicitis present in two pregnant patients at advanced gestational age was not statistically significant from nonpregnant. Laparoscopic appendectomy was performed in 6/8 (75%) of pregnant compared to 158/182 (87%) in nonpregnant (p = 0.415). Compared to the nonpregnant, the pregnant group has a more fecolith, positive peritoneal fluid culture, and wound infection, with E. coli more frequently isolated in 25%. None of the pregnant patients had an abortion, preterm labor, or mortality during or after surgery. In conclusion, laparoscopic appendectomy is a low-risk operation for pregnant with acute appendicitis.

Knowledge and attitudes towards Zika virus among medical students in King Abdulaziz University, Jeddah, Saudi Arabia.

Zika Virus (ZIKV) and its associated consequences remain vital public health challenge of international concerns. The current study was done to assess knowledge and attitudes towards ZIKV and the factors associated with good knowledge among medical students in King Abdulaziz University, Jeddah. A cross-sectional study was conducted among 426 students. They were selected through multistage stratified random sample method, 2016. A validated, confidential, interviewing questionnaire contained 25 knowledge and 10 attitude items was used. Descriptive and inferential statistics were done. Results revealed that Facebook was the commonest source of ZIKV information. About half of the participants correctly identified mosquito bites and vertical route as ZIKV transmission modes. However, smaller percentages recognized the sexual and blood transmission modes. Calculations of knowledge score revealed that 77.5%, 15.0%, and 7.5% of the participants obtained poor, fair, and satisfactory scores, respectively. Age, educational year and attending ZIKV training were significantly associated with good knowledge (p<0.05). Concerning attitudes, about half of the participants agreed that ZIKV could add new burden on healthcare system of the affected countries. Most of participants were interested in learning more about ZIKV, emerging diseases and travel epidemiology. In conclusion, medical students had limited knowledge about ZIKV, and good attitudes towards learning about it. Conduction of ZIKV educational programs, and development of courses about emerging disease epidemiology are required.
