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.

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.

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.

Clinical usefulness of multigene screening with phenotype-driven bioinformatics analysis for the diagnosis of patients with monogenic diabetes or severe insulin resistance.

AIMS: Monogenic diabetes is clinically heterogeneous and differs from common forms of diabetes (type 1 and 2). We aimed to investigate the clinical usefulness of a comprehensive genetic testing system, comprised of targeted next-generation sequencing (NGS) with phenotype-driven bioinformatics analysis in patients with monogenic diabetes, which uses patient genotypic and phenotypic data to prioritize potentially causal variants. METHODS: We performed targeted NGS of 383 genes associated with monogenic diabetes or common forms of diabetes in 13 Japanese patients with suspected (n = 10) or previously diagnosed (n = 3) monogenic diabetes or severe insulin resistance. We performed in silico structural analysis and phenotype-driven bioinformatics analysis of candidate variants from NGS data. RESULTS: Among the patients suspected having monogenic diabetes or insulin resistance, we diagnosed 3 patients as subtypes of monogenic diabetes due to disease-associated variants of INSR, LMNA, and HNF1B. Additionally, in 3 other patients, we detected rare variants with potential phenotypic effects. Notably, we identified a novel missense variant in TBC1D4 and an MC4R variant, which together may cause a mixed phenotype of severe insulin resistance. CONCLUSIONS: This comprehensive approach could assist in the early diagnosis of patients with monogenic diabetes and facilitate the provision of tailored therapy.
