まとめ
高周波のサクラ神経刺激 (600 Hz) は,尿道門の活動を減少させることで,脊髄損傷 (SCI) の患者の膀の排泄を改善する可能性があります. このアプローチはリゾトミーを回避し,重要な反射や感覚を保ちます.
科学分野:
- 神経科学は神経科学である.
- 泌尿器科 泌尿器科とは
- バイオメディカルエンジニアリング
背景:
- 脊髄損傷 (SCI) は,しばしば神経原性の膀機能不全を引き起こし,デトルーザー-スフィンクター不協働によって特徴付けられます.
- サクラ前根刺激 (SARS) は膀の排泄を助けますが,尿道門の反射収縮によって妨げられます.
- スフィンクターの活動を減らすためのリゾトミーのような現在の方法も,有益な反射や感覚を損なう.
研究 の 目的:
- 尿道門の活動を減らすための高周波 (600 Hz) のサクラル神経刺激 (SNS) の実現可能性と有効性を評価する.
- 600HzのSNSがSCIを有する個体における下部泌尿器系および腸機能に与える影響を評価する.
- デトゥルソール-スフィンクター不協和症の管理のためにリゾトミーの代替案を探求する.
主な方法:
- すでにSARSデバイスを埋め込んだSCIを有する個人を対象とした概念実証研究.
- 膀圧,尿路圧,直腸圧,門圧,そして骨盤床電気ミオグラムの測定.
- 20 Hz と 600 Hz の SNS 周波数の比較.
主要な成果:
- 20Hzと600Hzの両方のサクラ神経刺激は実行可能であり,よく耐えた.
- 刺激の頻度は下部泌尿器系と腸の機能に影響を与えました.
- 1人の参加者の場合,600 Hz SNSは,20 Hz SNSと比較して尿路圧を大幅に低下させた.
結論:
- 高頻度のSNSは,SCIにおける尿管門の活動を管理する可能性を示しています.
- このアプローチは,神経機能を保ち,根茎切除の代替案を提供することができる.
- 600 Hz SNSを最適化して,SCI患者における膀の排泄効率を向上させるため,さらなる研究が必要である.

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...
Drugs for Treatment of Diarrhea-Predominant IBS
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
Urinary Tract Calculi III: Medical Management
The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...
Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
