Survey of medications for myelomeningocele patients over their lifetime in Japan.

BACKGROUND: This study aimed to investigate medication prescriptions for patients with myelomeningocele (MMC) across different age groups, particularly in adulthood and after middle age. METHODS: The Japan Medical Data Center (JMDC) database, based on medical claims data, was utilized for this analysis. Patients were divided into 10-year age groups, and prescriptions for analgesics, anticonvulsants, psychotropic drugs, lifestyle disease-related drugs, drugs for urinary incontinence, and laxatives were examined. To compare the differences in the utilization of medications unrelated to lifestyle-related diseases across different age groups, the data was categorized into three age groups: 19 or under, 20-39, and 40 or older. RESULTS: Among the 556 MMC patients, the percentage of those regularly prescribed analgesics increased from 2.8% in patients ≤ 19 to 31.7% in patients 40 or older (p < 0.01). Psychotropic medication use also increased with age, rising significantly from 6.3% in patients ≤ 19 to 34.6% in patients 40 or older (p < 0.01). Patients with MMC showed an increasing trend in prescriptions for lifestyle-related disease medications compared to the normal control group. Notably, the percentage of patients in their 30 s taking hypertension medication was 4.9%, significantly higher than the 0.86% in the control group (p = 0.029). In their 40 s, 22.9% of MMC patients were prescribed hyperlipidemia medication, significantly higher than the 3.9% in the control group (p < 0.01). CONCLUSION: Comprehensive multidisciplinary support and follow-up are crucial to enhance the quality of life for MMC patients, with particular attention to pain management, psychological care, and treatment of lifestyle-related diseases.

Comparison of intraoperative neurophysiological monitoring methods for lumbosacral lipoma surgery in infants.

BACKGROUND: Stable intraoperative neurophysiology monitoring of infants, especially very young infants, is challenging. In this study, motor evoked potentials (MEPs), the bulbocavernosus reflex (BCR), and somatosensory evoked potentials (SEPs) were simultaneously monitored in infants with lumbosacral lipomas, and these methods were compared retrospectively. METHODS: A total of 21 surgeries performed for lumbosacral lipoma in patients less than 1 year old were studied. The mean age at surgery was 133.8 days (range 21-287 days; ≤ 120 days: 9 cases, > 120 days: 12 cases). Transcranial MEPs were measured in the anal sphincter and gastrocnemius, and tibialis anterior and other muscles were added as needed. The BCR was measured by the electromyogram of the anal sphincter muscle with stimulation of the pubic region, and SEPs were measured from the waveforms of stimulation of the posterior tibial nerves. RESULTS: For the BCR, stable potentials could be recorded for all 9 cases at ≤ 120 days of age. In contrast, for MEPs, stable potentials could be recorded in only 4 of 9 cases (p < 0.05). For all patients > 120 days of age, MEPs and the BCR were measurable. SEPs were undetectable in some patients regardless of age. CONCLUSION: The BCR could be more consistently measured than MEPs in infant patients with lumbosacral lipoma at ≤ 120 days of age.

The effect of shunt removal on the quality of life in patients with congenital hydrocephalus.

BACKGROUND: Although there have been reports investigating the quality of life of patients who underwent ventriculoperitoneal shunting or endoscopic third ventriculostomy (ETV) for congenital hydrocephalus, there have been no studies of the quality of life of patients after ventriculoperitoneal shunt (VPS) removal. In the present study, a survey of pediatric and congenital hydrocephalus patients was conducted to compare the quality of life of patients with a remaining VPS with that of patients who had the shunt removed. METHODS: Between February 2020 and November 2021, an outpatient survey was administered to patients 8 years of age and older who had undergone VPS due to a diagnosis of congenital hydrocephalus. The Hydrocephalus Outcome Questionnaire (HOQ) was used to assess the quality of life for this study. The HOQ scores (overall health score, physical health score, cognitive health score, and social-emotional health score) were compared among three groups: a VPS-remaining group, VPS-removed with endoscopic third ventriculostomy (ETV) group, and VPS-removed without ETV group. RESULTS: The total number of patients who underwent VPS for hydrocephalus was 71, with 47 in the VPS-remaining group, 14 in the shunt-removed with ETV group, and 10 in the shunt-removed without ETV group. The HOQ overall health score was 0.68 for the VPS-remaining group, 0.74 for the shunt-removed with ETV group, and 0.74 for the shunt-removed without ETV. There were no significant differences between the VPS-remaining group and the VPS-removed with or without ETV groups (p = 0.3255, 0.4178, respectively). CONCLUSION: There was no significant difference in the quality of life between patients with a remaining VPS and those who had their VPS removed with or without ETV.

Newborn with severe supratentorial subdural hematoma due to laceration of the tentorium cerebelli.

PURPOSE: A rare case of a newborn girl born by a normal vaginal delivery who developed a severe supratentorial subdural hematoma due to a laceration in the tentorium cerebelli is presented. METHODS AND RESULTS: The girl, born by normal vaginal delivery at 39 weeks and 4 days of gestation, showed an intermittent decrease in oxygen saturation and bulging of the anterior fontanelle. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a subdural hematoma centered in the left occipital region with a midline shift. Hematoma evacuation with craniotomy was performed, and the source of bleeding was a laceration of the tentorium cerebelli. CONCLUSION: Severe supratentorial subdural hematomas can occur due to laceration of the tentorium cerebelli even in a normal vaginal delivery.

A ventricular catheter that migrated into the fourth ventricle successfully removed using a neuroendoscope.

BACKGROUND: In order to remove a foreign body in the ventricle, such as a ventricular drainage catheter, craniotomy and corticotomy are required to access the ventricle. A case in which a catheter in the 4th ventricle was safely removed with a flexible neuroendoscope is reported. CASE DESCRIPTION: A 47-year-old man underwent coil embolization and ventricular drainage for subarachnoid hemorrhage. 10 days after the operation, he tore off the ventricular drainage catheter and the catheter remained intracranially. The tip of the catheter was in the 4th ventricle and the operation to remove remaining catheter with a neuroendoscope was performed. Using a neuroendoscope, we could remove the catheter safely and did not detect the complications. CONCLUSION: To date, there have been no reports of cases in which a drainage catheter in the ventricle was removed using a flexible endoscope. This case suggests that a flexible endoscope is useful for removing a foreign body from the ventricle less invasively.

Treatment of refractory giant suprasellar arachnoid cyst by endoscopic expansion of a fenestrated stoma.

Background: Although endoscopic ventriculo-cysto-cisternostomy is considered to be effective for suprasellar arachnoid cysts, we encountered a giant suprasellar arachnoid cyst that recurred despite surgery using this technique. Case Description: The patient was a 9-month-old boy. Magnetic resonance imaging revealed a huge suprasellar arachnoid cyst extending from the suprasellar region to the anterior skull base and both middle cranial fossa. First, an endoscopic procedure was performed to open the cyst wall between the right ventricle and the cyst and between the cyst and the prepontine cistern. Although the cyst initially shrank, it recurred over the next 2 months, and hence, we performed another endoscopic surgery. At the second surgery, both the previously opened stomas were found to be occluded. To reopen the cyst wall between the ventricle and the cyst, multiple holes were made with monopolar electrodes, and forceps were used to connect the holes by grasping and twisting the cyst wall so that the stoma was much larger than at the previous surgery. Postoperatively, the cyst shrank and the patient's head circumference stopped expanding. Conclusion: Following the treatment of large cysts, the stoma might become narrower as the cyst shrinks, resulting in obstruction. Using the technique reported here might prevent occlusion of large arachnoid cysts.

Stent-Assisted Coil Embolization of Ruptured Blood Blister-Like Aneurysm of the Basilar Artery: A Case Report and Literature Review.

Objective: Blood blister-like aneurysms (BBA) often develop on the anterior wall of the internal carotid artery, and few cases have been reported at other sites. We report a case of stent-assisted coil embolization in the acute phase for a ruptured BBA of the basilar artery. Case Presentation: A 53-year-old woman underwent emergency stent-assisted coil embolization for subarachnoid hemorrhage due to a ruptured BBA in the main trunk of the basilar artery. Seven months after the operation, cerebral angiography confirmed no recurrence and a good clinical course. Conclusion: Stent-assisted coil embolization for BBA may be one treatment option.

Retinal detachment with retinal pigment epithelial tear under hypotony after trabeculectomy: A case report.

PURPOSE: To report a case of retinal detachment with retinal pigment epithelium (RPE) tear, under hypotony after trabeculectomy, which immediately resolved upon elevation of intraocular pressure. OBSERVATIONS: A 67-year-old man who had undergone trabeculectomy presented for treatment of a visual field defect in his left eye. His glaucoma surgery was uneventful. At his first visit to our clinic, the patient's visual acuity was 15/20 in the right eye and 20/40 in the left; intraocular pressure was 18 mmHg in the right and 5 mmHg in the left. Fundus examination of the left eye revealed a retinal detachment, overlying a choroidal detachment, and an RPE tear. The retinal detachment did not resolve with systemic steroid pulse therapy or vitrectomy. The patient was then diagnosed with an exudative retinal detachment with RPE tear under hypotony, and transconjunctival sutures were applied to tighten the scleral flap, to elevate intraocular pressure. After the transconjunctival sutures were applied, intraocular pressure increased to 10 mmHg and the exudative retinal detachment immediately resolved. There was no recurrence of retinal detachment after the intervention. CONCLUSIONS AND IMPORTANCE: Because there have been few case reports of retinal detachment with an RPE tear after glaucoma filtering surgery, no therapeutic strategy has yet been proposed. The findings in this case indicate that intraocular pressure elevation is effective for treating exudative retinal detachment with RPE tear in cases of hypotony after glaucoma filtering surgery.
