Adolescent idiopathic scoliosis is the most common form of scoliosis, with severe cases leading to a decline in patients with worsening angulation of deformity. Technical nuances of spinal flexibility and cord type based on the extent of the deformity may impact operating safety and outcome, with risks including neurological loss during and after surgical intervention. Here we present a case of posterior osteotomy and correction of a patient with adolescent idiopathic scoliosis with a T2 - L3 fusion in which transcranial motor evoked potentials (TcMEPs) and somatosensory evoked potentials (SSEPs) were lost intraoperatively, thus requiring application of operative consensus guidelines for the loss of neuromonitoring data. Particularly, the discussion focuses on the decision-making process that resulted in the complete recovery of TcMEPs and SSEPs post-operatively.

Lower back pain (LBP) is a frequent complaint, even among young people. The most common cause is attributed to slipped discs or vertebral fractures. Less common etiologies should also be considered when presenting with typical symptoms of severe backache. Here, we are presenting one such uncommon case. A 32-year-old man with a history of meningocele repair in neonates presented with severe backache, urinary retention, and constipation in an emergency. Initially, the patient was treated elsewhere, but symptoms persisted. A contrast-enhanced MRI done in the emergency revealed a rare sacral spinal epidural arteriovenous fistula (SEDAVF) with cord congestion. The patient was taken up for digital subtraction angiography, which confirmed the diagnosis, and was treated successfully with endovascular embolization. This case highlights the complex presentation of SEDAVF and the importance of prompt diagnosis and intervention.

Cavernous sinus syndrome (CSS) is a complex, multifactorial condition that presents with a myriad of signs and symptoms including ptosis, double vision, and headache. We present the case of a 65-year-old woman with a chief concern of left-eye pain, including polio syndrome and hip replacement surgery. Unlike typical CSS cases often linked to tumors, this patient\'s condition involved a carotid-cavernous fistula (CCF), multiple internal carotid artery aneurysms, and a pericallosal aneurysm, without any associated tumor. She presented with severe left eye pain, ptosis, double vision, vomiting, headache, and other neurological symptoms since she woke up. Her treatment at a tertiary care center included diagnostic imaging, a cerebral angiogram, and embolization procedures, and she was discharged in stable condition. This case adds significant value to the medical literature by documenting the successful management of CSS with multiple aneurysms and a CCF, highlighting the importance of personalized treatment strategies and the effectiveness of modern embolization techniques in complex neurological conditions.

BACKGROUND: National commercial surveys are used to assess patient satisfaction. However, the information obtained does not always correspond to the clinical situation and therefore may be inadequate to help improve a specific patient experience when through no fault of its design, results in low response rates and inadequate specifics.
OBJECTIVE: The objective is to investigate patient satisfaction using real-time in-person patient experience survey responses at the end of a neurosurgical clinic visit and review the results from these survey responses and those from national commercial survey responses provided by the hospital for the ability to affect change.
METHODS: This is a prospective study from October 2023 to December 2023 during which a paper copy of 10 questionnaires derived from a national commercial outpatient clinical survey was given to every unique patient who was neurologically capable of filling it out at the end of his or her neurosurgery clinic visit. The electronic medical record was used to collect patient demographics and details of the clinic visit. National commercial survey responses from July 2022 to November 2023 provided by the hospital were reviewed.
RESULTS: A total of 149 patients were seen in the neurosurgery clinic from October 2023 to December 2023, 121 patients were given the in-person patient satisfaction survey, and the response rate was 100%. The mean age was 46.5 years with females constituted 45.5% of the patient sample. The visit type included 46 (38.0%) new patients, 53 (43.8%) returning patients, and 22 (18.2%) post-op patients, of which 45.5% presented with cranial pathologies. Comparing the patient satisfaction level between those seen by one provider and those seen by two providers, such as resident, or mid-level with attending, patients seen by two providers were less satisfied with \"feeling respected by the providers\" (4.92 vs. 4.64, p=0.0088), \"feeling listened to by the providers\" (4.84 vs. 4.50, p=0.0180), and \"feeling appreciated that the providers discussed illness prevention\" (4.72 vs. 4.29, p=0.0232). Due to a lack of necessary information from our national commercial outpatient clinic survey responses provided by the hospital, a direct comparison between the in-person survey and our national commercial outpatient clinic survey was not made.
CONCLUSIONS: Patient satisfaction surveys when not given in real-time in-person run the risk of low response rate and lack of specifics to help guide providers in quality improvement. Our data supports the use of real-time in-person patient satisfaction surveys that not only increase response rate but also provide useful information to help improve patient experience.

A ventriculoperitoneal (VP) shunt is a connection between the cerebral ventricles and the peritoneal cavity. One of the rare complications of this procedure is shunt migration and perforation of the bowel. Our case report presents the case of a 19-month-old male patient who underwent VP shunt insertion due to hydrocephalus at the age of 8 months. He suffered from two episodes of bacterial meningitis at the ages of 11 and 15 months, requiring hospital admission. The patient\'s parents brought him to the emergency department after noticing a blood-stained diaper and seeing a part of the shunt extruding from the anal opening. Upon physical examination, the patient was active, neither in distress nor tachycardic. with unremarkable abdominal examination and negative peritoneal signs. A digital rectal examination showed normal anal tone, with normal-coloured stool with no blood at the tip of the finger, together with a compressible VP shunt. Complications of this type of migration include faecal contamination and possible infections such as ascending meningitis. This case report highlights the extrusion of the shunt through the anal orifice in a 19-month-old male patient which serves as an example of the uncommon but serious consequence of VP shunt insertion in the pediatric population. While VP shunt insertion remains a widely used and effective treatment for hydrocephalus, healthcare providers need to recognize and address potential complications associated with this procedure. Additionally, this case emphasizes the importance of diligent monitoring and regular radiographic imaging to confirm the correct positioning of shunt components, particularly in the paediatric population.

Prolactinomas are benign pituitary tumors also known as prolactin-secreting adenomas (PSA). These tumors cause excessive secretion of prolactin (hyperprolactinemia), a hormone responsible for lactation. Diagnosing hyperprolactinemia relies on measuring prolactin levels in the blood, and elevated serum levels of prolactin are typically indicative of prolactinoma. The hook effect occurs in immunological tests such as the prolactin level test. When the amount of prolactin present in the sample is too high and exceeds the binding capacity of the antibodies being used, the test result may indicate falsely low levels of prolactin, which is the hook effect. The present study describes the case of a male patient who presented with neck pain and difficulty swallowing. MRI revealed a giant (>40mm) extradural tumor affecting the clivus, anterior fossa, pterygopalatine, and bilateral infratemporal fossae as well as the petrous apex and bilateral cavernous sinuses. Endocrinological investigation yielded no specific abnormalities. An occipitocervical fixation (arthrodesis) was proposed with simultaneous extended endoscopic endonasal resection. Surgery succeeded in resecting a portion of the clival tumor and the anterior fossa. Measurement of prolactin levels several weeks post-surgery found them to be extremely high, confirming the hook effect.

The implementation of artificial intelligence (AI) in radiology has shown significant promise in the identification of acute intracranial hemorrhages (ICHs). However, it is crucial to recognize that AI systems may produce false-positive results, especially in the postoperative period. Here, we present two cases where AI prioritization software erroneously identified an acute ICH on a postoperative non-contrast CT. These cases highlight the need for a more careful radiology review of AI-flagged images in postoperative patients to avoid further unnecessary imaging and unwarranted concerns from radiologists, clinicians, and patients.

Dexmedetomidine has been widely studied in many surgical settings, with possible benefits in lowering anesthetic requirements, improving perioperative hemodynamic stability, and improving postoperative outcomes. This systematic review aims to evaluate the effects of dexmedetomidine in patients undergoing transsphenoidal resection of pituitary adenoma, shedding light on its potential as an adjunctive agent in anesthesia for this specific surgical population. In this review, we searched PubMed, Cochrane Library, Scopus, Web of Science, and Google Scholar from inception to July 20, 2023. A total of six randomized clinical trials (RCTs) investigating the effects of dexmedetomidine versus placebo in patients undergoing transsphenoidal resection of pituitary adenoma were included in this review. The outcomes of interest were extracted from the included studies as mean difference (MD) and standard deviation (SD), then analyzed using the Review Manager (RevMan, RevMan International Inc., New York, USA) software. Our literature search process retrieved 274 records. Of them, six studies were included in the meta-analysis. There was a significant difference between the dexmedetomidine group compared to the placebo group in terms of heart rate at the end of the surgery (MD = -16.5; CI = [-25.36 to -7.64]; P value = 0.0003) and after extubation (MD = -16.81; CI = [-23.18 to -10.43]; P values < 0.00001). Furthermore, dexmedetomidine significantly reduced the mean arterial blood pressure (MAP) at after both intubation and extubation (MD = -9.11 and -21.5; CI = [-13.56 to -4.65] and [-30.93 to -12.06]; P values < 0.00001). This systematic review and meta-analysis demonstrated that dexmedetomidine appears to have several potential benefits in patients undergoing transsphenoidal resection of pituitary adenoma. The use of dexmedetomidine was associated with reductions in heart rate, mean arterial blood pressure, blood loss, and duration of surgery, while showing no significant difference in propofol dose or time to extubation of the trachea.

Moyamoya disease (MMD) is a rare cerebrovascular disease characterized by non-atherosclerotic and non-inflammatory progressive narrowing of the intracranial part of the carotid artery and its proximal branches. The disease process is commonly associated with the development of weak, dilated collateral blood vessels at the base of the brain. This gives it a classic smoky appearance on cerebral angiograms and hence the name \"Moyamoya\" which means \"puff of smoke\" in Japanese. When a patient has similar vasculopathy in the setting of another disease then it is known as Moyamoya syndrome (MMS). The associated diseases are sickle cell anemia, neurofibromatosis, long-standing diabetes, uncontrolled hypertension, or chemotherapy. Despite being known as a disease of the East Asian population, the disease is no longer exclusive to Asians, as evidenced by the rising incidence among non-Asian groups such as Caucasians, Hispanics, and African Americans. Patients can remain asymptomatic or present with ischemic or hemorrhagic stroke, headache, seizures, or recurrent transient ischemic attacks. Conventional cerebral angiography is considered the gold standard for diagnosing MMD. Treatment may be supportive, medical, or surgical. We present the case of a 42-year-old African American woman with several comorbidities who presented with sudden onset of ischemic stroke and upon further workup was found to have MMD. Equally important is to identify the most effective therapeutic approaches based on individual patients to achieve better clinical outcomes. Our case report highlights the importance of surgery in symptomatic MMD with a lack of supporting evidence indicating the benefits of dual antiplatelet therapy (DAPT).

Chronic subdural hematoma (cSDH) is a common condition that typically requires surgical intervention. Middle meningeal artery embolization (MMAE) has emerged as a potential alternative treatment option, although the choice of embolization material remains a topic of debate. In this case series, we report on the outcomes of 10 patients with cSDH who underwent MMAE. Most patients experienced symptom relief and a significant reduction in cSDH size post-procedure. Despite the presence of comorbidities and risk factors, most patients had positive outcomes following MMAE treatment. Only one patient required surgical intervention after the MMAE procedure due to the progression of symptoms, while MMAE successfully prevented recurrence in most patients. Our findings suggest that MMAE can be a promising treatment option for selected patients with cSDH. However, further studies are needed to compare the efficacy and safety of different embolization materials in MMAE procedures for cSDHs.
