Cranioplasty is a common neurosurgical procedure that follows hemicraniectomy in the setting of neoplasm resection or increased intracranial pressure. Although standardized practices aim at minimizing infection risk, infection of the surgical site has been reported in 6.6%–8.4% of patients. In this work, we document the novel use of synthetic dissolvable antibiotic-impregnated calcium sulfate beads (STIMULANⓇ Rapid Cure, Biocomposites Ltd, Wilmington, NC, USA) in five cases of cranioplasty at our institution. Four patients experienced wound healing as expected with no complications related to the use of Stimulan beads. One patient's clinical course was complicated by pseudomeningocele with superficial wound infection occurring 74 days following cranioplasty. Of note, this patient had suffered an avulsion injury and subgaleal hematoma of the scalp ipsilateral to the cranial incision, predisposing to infection due to incompetent scalp vasculature. No complications could be directly attributed to the use of STIMULANⓇ beads. [ABSTRACT FROM AUTHOR]

Simple Summary: Due to limited published data and a lack of formal guidelines, the management of leiomyogenic spine tumors (LTS) is challenging. Here, we report the clinical characteristics of patients with LTSs, analyze treatment modalities and outcomes, and highlight prognostic factors associated with morbidity and survival. Additionally, we endeavor to delineate the efficacy of en bloc resection versus other surgical techniques and understand the impact of surgical techniques on surgical outcomes. In this study, we performed a systematic review of the literature to encapsulate the clinical characteristics of patients afflicted with LTSs, analyze treatment modalities and outcomes, and highlight prognostic factors that inform clinicians on morbidity and survival. The study cohort consisted of 83 patients with a mean age of 49.55 (SD 13.72) with a female preponderance (60 patients). Here, 32.14% of patients had primary LTS; the remaining were metastases. Clinical presentation included nonspecific back pain (57.83%), weakness (21.69%) and radicular pain (18.07%). History of uterine neoplasia was found in 33.73% of patients. LTS preferentially affected the thoracic spine (51.81%), followed by the lumbar (21.67%) spine. MRI alone was the most common imaging modality (33.33%); in other cases, it was used with CT (22.92%) or X-ray (16.67%); 19.23% of patients had Resection/Fixation, 15.38% had Total en bloc spondylectomy, and 10.26% had Corpectomy. A minority of patients had laminectomy and decompression. Among those with resection, 45.83% had a gross total resection, 29.17% had a subtotal resection, and 16.67% had a near total resection. Immunohistochemistry demonstrated positivity for actin (43.37%), desmin (31.33%), and Ki67 (25.30). At a follow-up of 19.3 months, 61.97% of patients were alive; 26.25% of 80 patients received no additional treatment, 23.75% received combination radiotherapy and chemotherapy, only chemotherapy was given to 20%, and radiotherapy was given to 17.5%. Few (2.5%) had further resection. For an average of 12.50 months, 42.31% had no symptoms, while others had residual (19.23%), other metastasis (15.38%), and pain (7.69%). On follow-up of 29 patients, most (68.97%) had resolved symptoms; 61.97% of the 71 patients followed were alive. [ABSTRACT FROM AUTHOR]

Background: Although uncommon, cerebellar contusions are associated with significant morbidity and mortality. Literature is lacking in the prognostic and morphological factors relating to their clinical picture and outcomes, especially within children. The objective of this study is to evaluate prognostic and anatomic factors in the clinical picture of cerebellar contusions, including effacement of the 4th ventricle and cisterna magna. Methods: This is a retrospective chart review over 11 years across two medical centers. Patients included were under 18 years who presented with a cerebellar contusion. Patients were stratified within the study group based on discharge Glasgow outcome scale (GOS) and reviewed for prognostic factors contributing to outcome. Mid sagittal area of the 4th ventricle and cisterna magna were measured using magnetic resonance imaging and compared within the groups. Results: A total of 21 patients met the study criteria, of which 16 (76.2%) were male, with an average patient age of 8.65 years. Poor outcome at discharge (GOS <4) was associated with decreased admission Glasgow coma scale (P = 0.003), admission motor response (P = 0.006), pupil reactivity (P = 0.014), presence of concomitant subarachnoid hemorrhage (P = 0.010), contusion volume (P < 0.001), and decreased area of the cisterna magna (P = 0.012). Patients with poor outcomes were also more likely to require surgical intervention (P = 0.042). Conclusion: There are multiple prognostic factors associated with the overall outcome following cerebellar contusions. The rate of good outcomes in this study was superior to that in previous studies in adults. [ABSTRACT FROM AUTHOR]

Objective: Mixed gangliocytoma-pituitary adenomas (MGPAs) are very rare sellar neoplasms. Contemporary understanding of their natural history, clinical characteristics, optimal management strategies, and prototypical outcomes remains poorly understood., Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, PubMed, EMBASE, Web of Science, and Cochrane were searched to include studies of patients with histologically confirmed Mixed Gangliocytomas (MGPAs). Clinical features, management strategies, and outcomes were analyzed., Results: 33 studies reporting 78 patients met study criteria and were included. Median age at diagnosis was 47 years, with a female predominance (71%). Common presenting symptoms included headache (49%), acromegaly (43%), and visual disturbance (20%). Growth hormone (GH) and prolactin were the most commonly elevated hormones. Magnetic resonance imaging (MRI) identified local infiltration in 86% of patients, most frequently in the cavernous sinus. Transsphenoidal resection was the primary treatment strategy, which achieved a gross total resection (GTR) in 43%. Postoperative pituitary function was normal in 92%. Median follow-up was 21 months, during which time 14% of patients required secondary intervention for persistent hormonal hypersecretion. Following these secondary interventions and as of last follow-up, radiographic and/or biochemical control was confirmed in all patients, with an overall survival rate of 97%., Conclusion: MGPAs are rare, slow-growing tumors that present with a combination of endocrinological and neurological symptoms. MGPAs are optimally managed with transsphenoidal resection, which appears to achieve favorable rates of symptomatic relief and local control, despite the high incidence of local infiltration and relatively low attendant GTR rate., (Copyright © 2024.
