Acute spinal hematoma during pregnancy: A case report.

Background: Spontaneous spinal subdural-epidural hematoma during pregnancy is rare. Case Description: A 29-year-old gravida II patient experienced the onset of vomiting, headache, and progressive paraparesis. The initial non-contrast brain computed tomography and coagulation profiles were negative. The next day, the spine magnetic resonance imaging (MRI) revealed a C7-T4 epidural hematoma; contrast studies revealed no accompanying vascular lesions. On day 3, she underwent a cesarean delivery followed by a C3-T1 laminectomy. Her sensory and sphincteric function returned on postoperative day 2, but at 6 postoperative months, she continued to exhibit a 3/5 paraparesis. Conclusion: Pregnant patients with acute paraparesis should undergo STAT MRI screening of the spine to look for epidural/subdural hematomas.

Developing and validating a tool for assessing the confidence in the competence of midwifery tutors in India on WHO core competency domains.

Negligible quantitative research evidence exists on standardisation and psychometric validation of questionnaires that measure midwifery educators' confidence in their competence. This study developed a self-assessment of confidence in competence questionnaire in India based on the WHO Midwifery Educator Core Competencies (2014) with an aim to develop and validate a self-assessment tool measuring midwifery tutors' confidence in competence in imparting quality midwifery education. The questionnaire was developed as part of a multi-centre study to identify confident midwifery tutors for further training as educators, supporting India's rollout of professional midwives. The questionnaire underwent rigorous psychometric testing among 2016 midwifery tutors in India. Following exploratory Principal Component Analyses (PCA), the nine core competencies outlined in the WHO document were analysed separately. The results indicate that the questionnaire is psychometrically valid, with an internal consistency range of 0.81-0.93 for the nine domains. This robust testing process ensures the reliability and validity of the questionnaire. The self-assessment questionnaire can potentially be a valuable tool in India and other high-, middle-, and low-income countries. From a programmatic perspective, it can help identify key gaps and prioritise training needs, particularly in low-resource settings, so that limited resources are best utilised to fill the most prominent gaps. Furthermore, it can provide a universal platform for comparing data from different settings, facilitating global collaboration and learning in midwifery education.

Immunoexpression of Survivin and P53 in the Histological Subtypes of Medulloblastoma: A Cross-Sectional Observational Study.

Medulloblastoma (MB) is a common malignant intracranial neoplasms in children. The treatment and prognosis of this tumor depends on histology and molecular subtypes. Survivin, implicated in various malignancies, may hold prognostic significance. We investigated survivin and p53 immunoreactivity in different histological subtypes in 20 MB cases from January 2018 to June 2021. Immunohistochemistry revealed survivin expression in 75% (15/20) of cases, with cytoplasmic (10 cases), nuclear (four cases), or combined expression (one case). p53 nuclear expression was present in 35% (7/20) of cases. Classical variant MB exhibited predominant p53 and cytoplasmic survivin expression. Given the association of survivin and p53 expression with poor prognosis, especially in the prevalent classical variant, targeted therapies may hold promise for MB treatment advancement.

"Pediatric Spontaneous Intracranial Dissecting Aneurysms: Impact of Ischemic and Hemorrhagic Manifestations on Endovascular Treatment Strategies - Insights from a Developing World Setting".

BACKGROUND: Pediatric spontaneous intracranial dissecting aneurysms are rare, but systematic studies comparing hemorrhagic and ischemic presentations are lacking. This study addresses gaps in understanding their epidemiology, clinical presentation, management, and outcome. METHODS: A retrospective analysis of 23 pediatric patients with nontraumatic intracranial dissecting aneurysms treated between July 2018 and December 2023 was conducted. Patients were divided into 2 groups based on presentation: hemorrhagic (n = 16) and ischemic (n = 7). Clinical data were analyzed, including demographics, radiologic findings, treatment modalities, and outcomes. RESULTS: Clinical presentations varied, with limb weakness being more prevalent in hemorrhagic cases (P = 0.014), while headache and seizures were more common in ischemic cases. Angiographic analysis revealed distinct patterns, with hemorrhagic cases showing more distal involvement on vessel segments with stenosis and dilatation (pearl string sign). At the same time, the ischemic group exhibited the double-lumen sign. Various treatments, including microsurgery and endovascular techniques, were utilized, with perioperative complications observed, including one mortality in a hemorrhagic case. Multiple regression analysis identified significant risk factors for perioperative complications, namely, the configuration of the dissecting aneurysm (P = 0.016) and the type of presentation (P = 0.0006). Long-term Glasgow Outcome Scores were comparable, but patients with hemorrhagic manifestations experienced prolonged hospital and ICU stays (P = 0.001). CONCLUSIONS: Pediatric intracranial dissecting aneurysms, particularly hemorrhagic cases, are associated with severe neurologic deficits and higher perioperative complications. Despite similar long-term outcomes, hemorrhagic cases require prolonged hospitalization, increasing treatment costs. Optimizing management strategies for pediatric intracranial dissecting aneurysms, especially those with hemorrhagic features, is essential to improve outcomes and reduce healthcare expenditures.

Optimizing outcomes in multicompartmental brain tumor surgery: A comparative study of integrated endoscopic and microsurgical techniques versus endoscope-assisted microsurgery.

BACKGROUND: Multicompartmental lesions within the central nervous system are challenging due to their complex anatomy. This study evaluates the efficacy, safety, and utility of hybrid endoscopic and microsurgery versus endoscope-assisted microsurgery(EAM) for excising these lesions. METHODS: A retrospective comparative analysis was conducted on patients who underwent multicompartmental brain tumor surgery, utilizing either hybrid endoscopic and microsurgical techniques with the Endocameleon Hopkins telescope featuring a rotating lens system and knob (Karl Storz GmbH & Co., Tuttlingen, Germany), alternately used with a microscope (ZEISS PENTERO 800 S) (Group 1, n = 69), or endoscope-assisted microsurgery employing a fully high-definition, 45° angled endoscopic tool, QEVO®, integrated into the digital surgical microscope KINEVO 900 (Carl Zeiss Meditec, Oberkochen, Germany) as a plug-in feature (Group 2, n = 63), from July 2018 to March 2024. Data on demographics, clinical presentation, lesion characteristics, surgical details, and outcomes were meticulously collected and analyzed using rigorous statistical methods, including t-tests and chi-square tests. RESULTS: Compared to Group 2, Group 1 had better ease of dissection and visualization of bleeders (p = 0.01) and fewer postoperative hematomas (p = 0.04). Surgical times were similar (p = 0.134). Postoperative follow-up revealed fewer recurrences in Group 1, though not statistically significant (p = 0.33). Group 1 patients reported higher cosmetic satisfaction and shorter hospital stays (p = 0.002). Logistic regression identified tumor vascularity(p = 0.001) and ease of dissection(p = 0.008) as significant factors for recurrence. CONCLUSIONS: Hybrid endoscopic and microsurgery demonstrated superior intraoperative visualization, ease of dissection, and postoperative outcomes compared to endoscope-assisted microsurgery with the Quevo device. These findings suggest that the integrated approach may offer better outcomes for multicompartmental lesion excision regarding safety, efficacy, and patient satisfaction.

Unlocking the Battle-Clipping vs. Endovascular Therapy for Shunt-Dependent Hydrocephalus After Aneurysm Rupture: An In-Depth Institutional Analysis.

AIM: To compare microsurgical clipping and endovascular therapy (EVT) for the management of shunt-dependent hydrocephalus (SDH) in patients with subarachnoid hemorrhage (SAH) and hydrocephalus. MATERIAL AND METHODS: This retrospective study was conducted from July 2018 to December 2022 and included 67 patients with SAH accompanied by acute hydrocephalus. Patients' demographic, clinical, and radiological data, such as age, sex, Glasgow Coma Scale scores, Hunt and Hess scale, Fischer grade, external ventricular drain (EVD) duration, complications, Ommaya reservoir placement, cerebrospinal fluid drainage, and outcomes, were obtained. Statistical analyses, including univariate analysis and stepwise logistic regression, revealed significant risk factors for shunt dependence. RESULTS: Of the 67 patients, 33 underwent microsurgical clipping and 34 received EVT. Spasmolysis reduced shunt dependency, whereas early EVD placement correlated with reduced shunt dependence (p=0.002). The Ommaya reservoir helped in the management of meningitis but was found to be associated with shunt dependency (p=0.04). Multiple logistic regression analysis revealed that perioperative infarct was a significant risk factor for shunt dependence (p=0.05). No significant difference in patient outcomes was observed between the two treatment groups. However, patients who received EVT had shorter intensive care unit and hospital stays. CONCLUSION: This study shows that managing clinical vasospasm with spasmolysis may reduce shunt dependency. Overall, both microsurgical clipping and EVT offer similar long-term outcomes and efficacy in preventing shunt dependence, but the latter has the advantage of shorter hospital stay. These findings provide crucial insights for clinical decision-making and patient care in SDH after SAH.

Spontaneous thrombosis and calcification of giant cavernous carotid artery aneurysm: A rare case and management insights.

Background: Giant cavernous carotid artery aneurysms (>25 mm) are rare (3-5%), with some prone to spontaneous thrombosis (10-20% complete). We present a unique case of one of the largest aneurysms spontaneously thrombosing and calcifying. Case Description: A 57-year-old with persistent right-sided headaches had a substantial hyperdense mass in the right middle cranial fossa, eroding petrous bone. Magnetic resonance imaging and digital subtraction angiography revealed a giant cavernous segment fusiform aneurysm of the right internal carotid artery (ICA) with spontaneous thrombosis and distal ICA occlusion. Collateral circulation maintains the cerebral blood supply. Despite anatomical challenges, conservative management was chosen due to the patient's stability. Conclusion: This case highlights the complex interplay between thrombosed giant aneurysms and affected vessels, with unique features such as cross-flow, calcification, and bone erosion. We advocate conservative management for stable cases, supported by literature, emphasizing vigilant follow-up. This expands the spectrum of aneurysm presentations and encourages further research into their dynamics.

Navigating Uncharted Waters: Comparative Analysis of Clinical Progression and Outcomes in Vestibular Schwannoma Patients with Papilledema and without Hydrocephalus, Versus Those without Papilledema and Hydrocephalus: A Comprehensive Institutional Insight.

BACKGROUND: Papilledema's association with hydrocephalus (HCP)-linked larger vestibular schwannoma (VS) is established but cases lacking concurrent HCP require further investigation. METHODS: This retrospective comparative observational study, conducted from July 2018 to July 2023, examined 120 VS patients undergoing surgery. Patients were categorized into Group 1 (papilledema without HCP) and Group 2 (no papilledema or HCP), with comprehensive data analyzed. RESULTS: In this study, Group 1 (14 patients with papilledema) and Group 2 (106 patients without papilledema or HCP) were compared. Group 1 was younger (mean age 27.21 ± 11.73 years) than Group 2 (mean age 54.66 ± 11.44 years). Both groups had similar symptom durations and tumor detection times. Group 1 had increased vascularity (P = 0.001), elevated cisterna magna protein levels (P = 0.001), and a higher incidence of neurofibromatosis 2 (P = 0.003). They also experienced longer surgeries (P = 0.001) and more blood loss (P = 0.001), leading to extended postoperative complications. Group 2 showed improved postsurgery visual outcomes (P = 0.001), better Glasgow Outcome Scores (P = 0.001), enhanced facial nerve preservation (P = 0.002), and improved hearing on follow-up (P = 0.003). Logistic regression analysis highlighted prolonged surgery duration (P = 0.057) and papilledema (P = 0.0001) as significant factors influencing visual improvement. CONCLUSIONS: Patients with VS require preoperative fundoscopy evaluation due to potential visual loss and papilledema, even without HCP. Early treatment initiation enhances visual and hearing outcomes. Meticulous surgery is vital given the lesion's hypervascular nature and adherence to surrounding structures. Preoperative embolization may aid in preserving neurovascular structures. In developing countries with higher blindness rates, judicious noncontrast computed tomography brain evaluation is crucial for timely detection and treatment initiation of lesions like VS.

Non-trivial ground and excited state photophysics of a substituted phenol.

5-(tert-Butyl)-2-hydroxy-1,3-isophthalaldehyde (5-tBHI) shows solvent dependent single or dual emission. The photophysics of 5-tBHI has been studied in a variety of solvents and the results were compared with that of the methyl derivative of the probe as well as the 5-tBHI anion. It has been found that the intramolecular H-bonded conformer of 5-tBHI predominantly exists in non-polar solvents, and undergoes facile excited state intramolecular proton transfer (ESIPT). On the other hand, a dynamic equilibrium can be found in polar, protic solvents, even in the ground state, except in water. NMR analyses confirm the loss of aromaticity of the probe in the ground state via anion formation, in equilibrium with the solvent mediated intermolecularly H-bonded state, in neat polar protic solvents like methanol. The proton transfer process, either intramolecularly or intermolecularly, was found to be of the order of 1 ps, and even faster than the instrumental resolution in the case of water. The current finding provides important insights on the photophysics of this small, substituted phenol.

Cultural adaptation and psychometric evaluation of Childbirth Experience Questionnaire 2 in Karnataka state, India.

BACKGROUND: Women's birthing experience is a sensitive indicator of the quality of childbirth care and can impact the physical and mental health of both women and their neonates. Negligible evidence exists on Indian women's birth experiences and-to the best of authors' knowledge-no questionnaire has been tested in India for measuring women's birthing experiences. This study aimed to test the construct validity and reliability of the Kannada-translated Revised Childbirth Experience Questionnaire. METHODOLOGY: A cross-sectional survey was carried out among postnatal women (n = 251, up to six months postpartum, with a live healthy neonate) who had given birth at a public or private health facility using the Kannada-translated CEQ2 in two districts of Karnataka. Data were collected at participants' homes after seeking written informed consent. Model fit was determined by Confirmatory Factor Analyses. RESULTS: The 4-factor model of the CEQ2 showed good fit after deletion of one item (item 8, subcategory "participation") with CMIN = 1.33; SRMR = 0.04; GFI = 0.92, CFI = 0.98, TLI = 0.99, RMSEA = 0.037 and p value 0.002). The Cronbach alpha values were acceptable for the four subscales (0.92, 0.93, 0.97, 0.91) as well as for the overall 21-item scale (0.84). CONCLUSIONS: The Kannada-translated CEQ2 is a reliable tool to measure the childbirth experiences among Kannada-speaking women and can serve as a reliable ongoing evaluation of women's birth experiences.

Endovascular glue embolization of the medial posterior choroidal artery aneurysm: A case report and a literature review.

Background: The medial posterior choroidal artery (MPCA) aneurysm is extremely uncommon. Thus yet, just a few cases have been reported. Due to the deep position, narrow lumen, fragile walls, and extensive tortuosity, both endovascular and microsurgical procedures are strictly limited. A case study of successful endovascular glue embolization of a left MPCA aneurysm and a literature review is included in this report. Case Description: A 17-year-old female arrived at our institution 2 days after suffering a major intraventricular hemorrhage with a minor subarachnoid hemorrhage. Digital subtraction angiography revealed a left MPCA aneurysm. The patient underwent a successful endovascular glue embolization and had a favorable functional outcome. Conclusion: Endovascular glue embolization yielded favorable clinical and angiographic results in MPCA aneurysms where microcatheter access and maneuverability are challenging.

Removal and identification of a subconjunctival parasite by light and scanning electron microscopy.

Background: Ophthalmic dirofilariasis is an uncommon zoonotic parasitic infection caused by species of Dirofilaria, a dog tapeworm that is transmitted to human by mosquitoes. Man is a dead-end host for the parasite. Ophthalmic involvement is rare and includes periorbital, subconjunctival, subtenon, and intra-ocular involvement. We report the removal of a subconjunctival worm and identification by light microscopy (LM) and scanning electron microscopy (SEM). Purpose: : A 62-year-old female presented with complaints of redness, discharge, and foreign body sensation with difficulty in opening eyes in the left eye for the last 3 days. The patient is a non-vegetarian. On examination, her best corrected visual acuity in both eyes was 20/20. On slit lamp examination, there was a long, thin, round, coiled white subconjunctival live worm in the left eye superiorly. The rest of anterior segment evaluation, intra-ocular pressure, and fundus was normal in both eyes. The parasite was removed under local anesthesia from subconjunctival space [Video]. External surface morphology under LM revealed fine transverse cuticular striations with tapered cephalic and caudal ends. Uterus was long and coiled with indistinguishable masses inside. The finding was also confirmed by SEM. Synopsis: A subconjuctival parasite was removed and identified as Dirofilaria repens by characteristic LM and SEM findings. Highlight: Dirofilaria species may lodge in many tissues of human bodies including eye and adnexa. Dirofilaria is a natural parasite of carnivorous animals, mostly dogs, cats, and foxes.[1] The most common mode of transmission to human is usually by bite of mosquitoes like Culex and Aedes, which are considered as vectors, and it is often thought that parasitemia is because of accidental conduction.[1] Simple surgical removal of the worm is curative. After removal, the worm should be visualized directly under LM. All the internal structures of the transparent worm could be seen and compared with those under SEM.

Malignant Peripheral Nerve Sheath Scalp Tumor: A Short-Term Institutional Experience with Literature Review.

Malignant peripheral nerve sheath tumor (MPNST) of the scalp is rare. These lesions are associated with neurofibromatosis type 1 (NF1), but patients had been reported without NF1 also. We tried to analyze the difference between the clinical course and outcome of the patient with MPNST having stigmata of NF1 and without it. We included five patients treated over 3 years between July 2018 and July 2021 with diffuse scalp MPNST. Two of these five patients with MPNST of the scalp had neurocutaneous stigmata of NF1. Three were female and two males with an average age of 38.40 ± 18.48 years-the youngest with NF1 being a 19-year-old female. We found dull aching pain as the most typical complaint in all patients and a repeated episode of generalized seizure in one patient. In these cases, two patients with NF1 have highly vascular tumors and attained large sizes greater than 30 cm. These two cases required preoperative digital subtraction angiography (DSA) and embolization with n-butyl acrylate. Total excision of the tumor was done in all patients with radiotherapy. Metastases within 1 year were noted in two patients with NF1, and one of these two succumbed to her illness. The rest of the three patients without NF1 are under follow-up with no evidence of disease with a maximum follow-up of 2 years. Large MPNST (size > 20 cm) are rare and reported to have been associated with and without NF1. Patients with scalp MPNST with NF1 can achieve larger size with fast progression of tumor size and higher chances of recurrence and metastases.

Spontaneous Cervicothoracic Extradural Hematoma with Rare Presentation in Pediatric Patient with Stroke-Like Features in Association with COVID-19, Presenting as Management Dillemma.

Presentation of cervico-thoracic extradural hematoma in pediatric age is rare with stroke-like features. Its association with COVID-19 in the active stage of the disease had not been reported and its management presents a management dilemma as COVID-19 with stroke-like features. A 14-year-old boy was referred to our institute with complaints of sudden-onset upper and middle back pain, associated with loss of sensation below the middle of the back, sudden progressive weakness of both lower limbs (power 0/5) and upper limbs (power grade-2/5), and incontinence of urine, following bouts of vomiting 12 days back. There was no history of trauma, bleeding diathesis, etc. Blood investigation was suggestive of leukocytosis, and RT-PCR test for COVID-19 was positive with raised D-dimer, serum ferritin, and C-reactive protein. MRI spine was suggestive of cervicothoracic extradural hematoma extending from C5-D3 level and compressing the spinal cord. The patient refused surgical decompression and was managed conservatively, following which he improved with power grade in limbs to 4/5. Surgical decompression is the treatment of choice but the patient can sometimes improve on medical management. Association of COVID-19 with spontaneous cervicothoracic extradural hematoma had not been reported earlier in the active stage, but its role in inducing vasculopathy and increased chances of bleeding at the uncommon site had been reported in the literature, and it may precipitate such cervical epidural hematoma.

Management dilemma in a rare case of pituitary apoplexy with akinetic mutism in the setting of ruptured junctional brain aneurysm: A case report and literature review.

Backgound: Pituitary apoplexy is associated with stroke, head injury, and brain tumors. Still, its presentation due to the ruptured aneurysm is rare and its presentation with akinetic mutism has not been reported. Case Description: The patient in the present study is 21-year-old female who presented in our emergency department in an altered sensorium with Glasgow comma score (GCS) E2V1M1. She was intubated and resuscitated. Routine blood investigations, lipid profile, and hormonal studies were normal. Initial noncontrast computed tomography (NCCT) head revealed subarachnoid hemorrhage in the interhemispheric fissure and evidence of bleeding in the pituitary gland. Magnetic resonance imaging (MRI) brain was soon done, which showed an infarct and hemorrhage in the pituitary gland; there was an evidence of an infarct in the bilateral medial frontal gyrus, basal ganglia, and supplementary motor area. MR arteriography revealed an aneurysm at the left A1-anterior communicating artery (Acom) junction directed superomedially with diffuse spasm in a bilateral anterior cerebral artery. Pterional craniotomy was done with clipping of the aneurysm and evacuation of blood clots from the interhemispheric fissure and pituitary gland. Histopathology features suggestive of the non-functioning pituitary tumor with interspersed hemorrhagic necrosis. Intraarterial vasodilation with microcatheter injection was given, but vasospasm did not improve. Postoperatively, Levodopa was started. She used to track objects in front of her eye and started nodding her head in "yes and no fashion," with power in limbs improved to 3/5 at 6 months of follow-up. Conclusion: Pituitary apoplexy with ruptured A1-Acom junction aneurysm with nonfunctioning pituitary macroadenoma is rare, and its presentation with akinetic mutism has not been reported. As there is scarce literature suggesting an association between pituitary apoplexy and ruptured aneurysm, it is challenging to comment regarding its pathogenesis. Although akinetic mutism generally has a poor prognosis, it may respond to Levodopa with a better outcome.

Post Traumatic Hydrocephalus in Indian Subpopulation: An Institutional Experience.

AIM: To identify subgroups of cases with ventriculomegaly who will benefit from the cerebrospinal fluid (CSF) diversion procedures, n patients with post-traumatic hydrocephalus (PTH), and to identify the risk factors for its development to minimize its occurrence. MATERIAL AND METHODS: We analyzed 500 head injury cases who were admitted over a one and a half year period in our institute with PTH, to assess them for treatment benefit by CSF diversion procedures and associated risk factors for its development. The patients were assigned to one of three groups: Group 1 had ventriculomegaly with periventricular lucency (PVL), and raised intracranial pressure (ICP) 2.1% (10/500). Group 2 had ventriculomegaly with PVL, and normal opening pressure 1.75% (7/500) and Group three had no ventriculomegaly 95.75% (483/500). RESULTS: The incidence of radiological PTH in this study was 3.4% (17/500), and it developed after an average interval of 16.43 ± 23.7 (SD) in Group 1 and 19.76 ± 8.9 (SD) weeks in Group 2. Lower Glasgow Coma Score (GCS) (p < 0.001), decompressive craniotomy (p < 0.001) and requirement for prolonged ventilatory support (p < 0.001) were significantly associated with the development of PTH. Significantly better results were found in cases with PTH and high opening CSF pressure (? 15 mmHg) on Lumbar puncture (p < 0.001). Decompressive craniotomy cases required significantly more shunt revisions compared to conservatively managed cases (p < 0.05). CONCLUSION: CSF diversion procedures help to improve ventriculomegaly cases with documented evidence of raised ICP but not in cases without raised ICP. The subgroup of PTH, which cannot be treated by CSF diversion procedures, can only be managed by minimizing many of the risk factors for its development. In cases with severe head injury, a low GCS, and prolonged ICU stay, decompressive craniotomy should be used judiciously. The duration of mechanical ventilation should be minimized and combined with necessary measures to improve GCS.

Comparative outcome of endovascular embolization with microsurgery in managing acute spontaneous cerebral hemorrhage in pediatric patients, an institutional experience.

OBJECTIVES: A few previous studies have reported the role of embolization with curative intent in the treatment of the early phase of a spontaneous cerebral hemorrhage in pediatric patients, and its efficacy needs to be compared with surgery at the same time risk factors for hemorrhage following early embolization in such patients need to be evaluated. METHODS: From a pool of 80 pediatric (< 18 years) who had undergone treatment for ruptured AVM with hemorrhage at our center between July 2018 and July 2022, we identified 36 patients with spontaneous bleeding due to AVM. Out of which, 20 were treated solely by embolization (group 1), while the remaining patients were treated surgically (with and without adjuvant embolization) (group 2). RESULT: Spetzler-Martin's grading of the lesion suggested seven lesions < 3 and 13 lesions ≥ 3 in the embolization group. Similarly, seven lesions were < 3 and nine ≥ 3 Spetzler-Martin grade in the surgery group. Incomplete embolization was associated with hemorrhage in two patients treated with curative intent and four patients treated with embolization as adjuvant in the surgery group (p = 0.01). On follow-up, 18 patients in the embolization group and 12 in the surgery group had Glasgow outcome scores ≥ 4 (p = 0.273). CONCLUSION: In the pediatric age group, incomplete embolization is the significant risk factor for hemorrhage in AVMs treated after a hemorrhagic stroke. Embolization with curative intent is as effective as surgery in treating such lesions as adjuvant embolization with careful patient selection.

Comparative Analysis of Clipping and Endovascular Therapy Outcomes in the Treatment of Ruptured Distal Anterior Cerebral Artery Aneurysms.

AIM: To compare the outcomes of distal anterior cerebral artery (DACA) aneurysm treatment using endovascular therapy (EVT) and surgical clipping, and to assess their risk factors. MATERIAL AND METHODS: We retrospectively sampled and analyzed 31 patients treated for ruptured Distal anterior cerebral artery (DACA) aneurysms from a larger sample of 250 patients treated for ruptured aneurysms between July 2018 and July 2021. The outcomes of patients who underwent clipping and EVT were compared using chi-square tests. T-tests were used for univariate analysis and a logistic regression analysis was used to determine the risk factors affecting outcomes. RESULTS: Of the 31 patients, 20 were treated with clipping and 11 with EVT. Patients treated with EVT had a mean age of 35.45 ± 6.66. The mean age of the clipping group was 44.4 ± 6.94 years (p=0.002). Intraoperative rupture was significantly more common in the clipping group (p=0.025). There were no significant differences in the postoperative incidence of vasospasm or hydrocephalus (p=0.12). Modified Rankin Scale scores (p=0.017) and Glasgow Outcome Scale scores (p=0.02) both at discharge and 6-month follow-ups were significantly better in the EVT group than in the clipping group. Length of stay in the Intensive Care Unit (ICU) was 9.27 ± 2.6 days following EVT and 23.60 ± 6.29 following clipping (p=0.001). Age (p=0.0136), Hunt and Hess grade (p=0.02), and the occurrence of intraprocedural rupture (p=0.009) were found to significantly affect outcomes. CONCLUSION: The outcomes of EVT were better than those for clipping and required a shorter stay in the ICU and the hospital. This may be partially attributable to the dual-trained neurovascular surgeon who performed the procedures. Older age, poorer Hunt and Hess grades, and intraoperative aneurysm rupture adversely affected outcomes.

COVID19-induced immunosuppression and aggressive progression of primary cranial vault lymphoma presenting as a management challenge, a case report, and a literature review.

Background: We needs to study Primary Large cell Non-Hodgkin's Lymphoma of the cranial vault, which is rare, and its association with COVID19 has not been reported, which may have an immunosuppressive effect to aggravate its progression. Patient details: Our patient, a 53-year-old male, noticed fast growth of posterior cranial vault lesion from 2 to 10 cm size in last 6 months after COVID 19 affliction. MRI brain with contrast revealed lesions suggesting meningioma. The whole-body PET scan was normal. Following Subtotal excision of the mass, histopathology revealed large B-cell Non-Hodgkin's lymphoma (DLBCL). Immunohistochemistry showed positive results for CD10, CD20, CD45 (LCA), ALK, and BCL-VE with a Ki-67 index of 90-95%. Following radiotherapy and chemotherapy patient is disease-free on imaging and doing well at 5 months of follow-up. Conclusions: Early intervention with excisional biopsy and timely chemo and radiotherapy in favorable immunostaining may add survival benefits even in malignant features induced by immunosuppressing diseases such as COVID19 in diffuse large B-cell lymphoma (DLBCL) of the scalp.
