Primitive myxoid mesenchymal tumour of infancy (PMMTI) is a rare mesenchymal tumour that typically appears in those under 6 months of age and preferentially affects the deep soft tissues of the trunk and paravertebral spinal regions. PMMTI has only recently been described, and there is scarce literature reporting cases regarding the management paradigm of the tumour. We report the case of an 11-week-old male who presented with bilaterally reduced movement and brisk reflexes in his lower limbs, and irritability. Despite numerous radiological investigations, including MRI, PMMTI was only diagnosed upon biopsy and histopathology. Although PMMTI is known to be relatively unresponsive to chemotherapy, we observed a notable decrease in tumour size after a series of chemotherapy sessions. After two-staged surgical resection of the tumour, the patient is currently stable and under close follow-up. In this article, we aim to report on the patient's clinical presentation, investigations, diagnosis, and treatment, while also discussing the findings from a review of the literature pertaining to future approaches in managing PMMTI. Overall, this case highlights the importance of considering PMMTI in the differential diagnosis of deep soft tissue tumours in young infants and the potential for a combination of chemotherapy and surgical resection to be effective in treating this rare tumour.

We describe a case of a young male patient with KRIT1-driven familial cavernous malformation syndrome who developed multiple brain cavernomas, intracranial bleeding, and persistent seizures. Due to the relentless growth of cavernous malformations and recurrent intracranial bleeds, it was decided to enrol the patient in the "Propranolol for Intracranial Cavernoma" (PICC) pilot trial at our institution. Over the 5-year treatment period with 20 to 40-mg oral propranolol three times daily (TDS), we noted the near-complete arrest of the growth of cavernous malformations with no further evidence of intracranial bleeding or any further seizures. The observed outcome is consistent with the extremely limited published literature on the topic; thus, this case provides important evidence that supports the use of propranolol as a prophylactic treatment for paediatric intracranial cavernomas. We strongly encourage and recommend future prospective randomised controlled trials to definitively assess and characterize the therapeutic utility of propranolol in this patient population.

AbstractIntroductionResearch QuestionResultsDiscussion and ConclusionParkinson’s disease is a common neurodegenerative disease. With an aging population, co-existent degenerative diseases of the spine in these patients will become more prevalent.This systematic review and meta-analysis aims to establish the incidence and risk of adverse outcomes following spinal surgery in patients with Parkinson’s disease. Material and Methods A literature review was carried out in order to identify studies assessing the outcomes of adult patients with Parkinson’s disease undergoing spinal surgery for degenerative conditions. Studies with less than ten subjects or those assessing surgery for spinal deformity or trauma were excluded.Of 74 studies identified, seven were included for meta-analysis. In the 689,578 participants, there was a significantly higher incidence, but not higher risk, of complications (0.54 95% CI [0.19–0.85] vs 0.07 95% CI [0.01–0.41]; p = 0.048) and revision surgery (0.6 95% CI [0.25–0.88] vs 0.1 95% CI [0.05–0.19]; p = 0.003) amongst patients with Parkinson’s disease compared to controls. We also demonstrated a significantly lower incidence but not lower risk of clinical improvement (0.27 95% CI [0.16–0.41] vs 0.57 95% CI [0.36–0.76]; p = 0.02) after surgery in patients with Parkinson’s disease. There was no difference in the incidence or risk of death following surgery.Spinal surgery for concomitant degenerative diseases in patients with Parkinson’s disease is associated with a lower incidence of clinical improvement and a higher incidence of complications. Medical management should be optimised before an individually tailored and well-considered surgical intervention is implemented. [ABSTRACT FROM AUTHOR]

Meningiomas are one of the most common benign primary brain tumors; however, there is a paucity of literature on potential preventability. This comprehensive review aimed to explore the existing evidence for the potential risk factors that may contribute to meningioma development and to discuss early prevention strategies. Literature search was conducted via MEDLINE, Embase, Web of Science, and Cochrane Database to retrieve existing literature on various environmental exposures and lifestyle behaviors that are potential risk factors for the development of meningiomas. Significant risk factors included exposure to ionizing radiation and certain environmental chemicals. Notably, this study also identified that cigarette smoking and obesity are associated with the development of meningiomas. To date, wireless phone usage, hormonal exposures, dietary factors, and traumatic brain injury remain inconclusive. Early prevention strategies should primarily be family-driven, community-based, and public health-endorsed strategies. Targeting unhealthy behaviors through healthcare organizations could execute a pivotal role in the maintenance of an optimum lifestyle, reducing the development of risk factors pertinent to meningiomas. To our knowledge, this is the first study that offers a perspective on prevention of meningiomas. A causal relationship of risk factors in developing meningiomas cannot be directly established with the current evidence. We are aware of the limitations of the hypothesis, but we believe that this study will raise more awareness and our findings could potentially be endorsed by organizations promoting health across the globe. Further prospective and retrospective studies will shed more light on this topic and help establish a definitive relationship. [ABSTRACT FROM AUTHOR]

Objective: To describe three cases of delayed development of intracranial hypertension (IH) after surgical treatment of intracranial arachnoid cyst, including the pathogenesis of IH and a review of the literature. Methods: A retrospective and prospective analysis of three male patients (two 18 years old and one 45 years old) was performed. All patients underwent surgical intervention for symptomatic intracranial arachnoid cyst in the form of fenestration of the cyst and a cystoperitoneal shunt. Results: All three patients presented at a later stage with new-onset headaches after the initial management of arachnoid cyst. Magnetic resonance imaging and magnetic resonance venography ruled out any intracranial vascular pathology. Lumbar puncture and intracranial pressure monitoring showed increased intracranial pressure suggestive of idiopathic IH. To manage IH, intracranial pressure monitoring, cystoperitoneal shunt, ventriculoperitoneal shunt, and lumboperitoneal shunt were performed. Conclusions: The pathogenesis of delayed development of IH in this clinical setting is not clearly elucidated. When intracranial arachnoid cysts are treated, the possibility of future development of IH should be borne in mind. Delayed presentation with headaches in patients after treatment of intracranial arachnoid cysts should raise the possibility of IH. [ABSTRACT FROM AUTHOR]
