Female Urinary Retention Progressing to Possible Multiple System Atrophy-cerebellar Form after 12 Years.

We herein report a 73-year-old Japanese woman with possible multiple system atrophy-cerebellar form (MSA-C) who suffered from urinary retention (sacral autonomic disorder) for 12 years before exhibiting cerebellar ataxia. A peculiar combination of findings on urodynamics and sphincter electromyography (EMG), e.g. detrusor hyperactivity with impaired contraction (DHIC), detrusor-sphincter dyssynergia (DSD) and neurogenic sphincter EMG (upper and lower neuron-type autonomic dysfunction), seems to have been predictive of future development of MSA.

Brain Diseases and Fall-Related Surgery in Older Persons.

BACKGROUND: It is known that age-related brain symptoms (gait difficulty and dementia) increase the likelihood of fall-related surgery. In contrast, it is not known which types of brain disease underlie such symptoms most. OBJECTIVE: The aim of this study was to correlate brain diseases with the types of surgeries performed at our hospital for patients who had fallen. METHODS: This was a retrospective study at a multifaculty university hospital in Japan, with a 12-month recruiting period, a follow-up period of 3.0 ± 2.5 weeks, and ≥1×/week visits. We assembled a neurogeriatric team to diagnose brain diseases with the use of brain imaging to the extent possible and correlated the diagnoses with types of fall-related surgery. RESULTS: Fall-related surgery was conducted by the orthopedics (OP) and neurosurgery (NS) faculties (total n = 124) at a ratio of about 2 to 1. The underlying brain diseases differed by faculty; for OP, surgery was most commonly performed in patients with a combination of white matter disease (WMD) and Alzheimer's disease (AD) (79%) followed by dementia with Lewy bodies. In contrast, for NS, the most common surgery was for patients with alcoholism (50%) followed by a combination of WMD and AD. CONCLUSION: Fall-related surgery was performed by the OP and NS faculties at a 2 to 1 ratio. The major underlying brain diseases were a combination of WMD and AD (79%) for OP and alcoholism (50%) for NS.

Increased biological antioxidant potential in the cerebrospinal fluid of transient global amnesia patients.

Oxidative stress may accompany the pathological process in transient global amnesia (TGA). We measured the biological antioxidant potential (BAP) in the cerebrospinal fluid (CSF) of TGA patients. We enrolled 13 TGA patients (7 men, 6 women; mean age 65.0 years [48-70 years]) and 24 control subjects (12 men, 12 women; mean age 38.2 years [17-65 years]; age did not correlate with csfBAP in this group). We performed brain MRI in all TGA patients, and CA1 lesions were noted by MRI in 5 subjects. We measured csfBAP, total antioxidant properties, in all TGA patients and controls. csfBAP levels were higher in TGA patients than in controls (p = 0.024, 0.028). csfBAP levels in TGA patients did not differ between MRI-positive and -negative subgroups. Elevated csfBAP levels were observed in TGA patients, suggesting that oxidative stress may have a role in the pathogenesis of TGA.

Lower Urinary Tract Symptoms in Myasthenia Gravis.

It remains uncertain to what extent lower urinary tract (LUT) symptom (LUTS) is a comorbidity of myasthenia gravis (MG). We prospectively administered a LUTS questionnaire devised for detecting neurogenic pelvic organ dysfunction (not validated) in an MG group and a healthy control group and compared the results. The MG group comprised 21 patients: 15 women and 6 men, with age range 22-73 (mean 47) years, illness duration range 0.2-8 (mean 3.5) years, median Myasthenia Gravis Foundation of America (MGFA) grade 2, all walking independently. Therapies included thymectomy in 17, predonisolone 5-20 mg/day in 10, and pyridostigmine bromide 60-180 mg/day in 9 patients. The control group, who were undergoing an annual health survey, comprised 235 consecutive subjects: 120 women and 115 men, with age range 30-69 (mean 48) years. The questionnaire had 9 questions. Each question was scored from 0 (none) to 3 (severe) with an additional quality of life (QOL) index scored from 0 (satisfied) to 3 (extremely dissatisfied). Statistical analysis was made using Student's t test. Compared with the control subjects, the frequency of LUTSs in the MG patients was significantly higher for daytime frequency (43%; p < 0.01), nocturia (24%; p < 0.01), and urinary incontinence (43%; p < 0.05). The LUTS-related QOL index for the MG patients was significantly higher for MG patients as a whole than that for all control patients (29%) (p < 0.05). In conclusion, our study results showed that MG patients had significantly more LUTSs (overactive bladder) than healthy control subjects and had worse LUTS-related QOL; therefore, amelioration of LUTS in MG is important.

Diabetic Cystopathy Occurs Independently from Other Atherosclerotic Risks.

It has not yet been clarified whether atherosclerotic risks other than diabetes are related to bladder small fiber neuropathy (cystopathy) in type 2 diabetes. The aim of this study was to answer this question by urodynamics. This was a retrospective study. The subjects were 44 patients: 27 male, 17 female; mean age 67.0 ± 12.7 years; mean duration of diabetes 16.8 ± 13.1 years; mean HbA1c 7.8 ± 1.2%. We analyzed the relationship between diabetic cystopathy (at least one of the following abnormalities in urodynamics: decreased bladder sensation, post-void residual, detrusor overactivity, low-compliance detrusor) and clinical items, i.e., severity and duration of diabetes, nerve conduction, body mass index, blood pressure, cardio-ankle vascular stiffness index, and ultrasound Doppler echography (plaque score, intima-media thickness) in these patients. As a result, urodynamic diabetic cystopathy was not correlated with any of the above systemic items. In conclusion, the above findings suggest that bladder small fiber neuropathy can occur independently from systemic atherosclerotic risks.

Triple-disease etiology is common for LUTS in octogenarians: a neuro-urological approach.

OBJECTIVE: Older individuals often have multiple etiologies for their lower urinary tract symptoms (LUTS); i.e., both urologic (U) and neurologic (N) etiologies. Few studies have investigated 'triple disease' (typically one U and two N components) in the LUTS of older adults. Herein, we had specialists from both urology and neurology address triple- and quadruple-etiology disease. PATIENTS AND METHODS: This was a retrospective study with a 12-month recruiting period. We ascertained LUTS by standard questionnaires and bladder diaries. Urodynamics, sphincter EMG, prostate echography, and a neurologic examination were conducted for each patient as well as neuroimaging and neurophysiology examinations when appropriate. The diagnoses of the etiologies were based on published criteria. RESULTS: We analyzed the cases of 141 older (age > 65 years) adults with LUTS referred from both urology (27%) and neurology departments (73%). The final etiologies were U (n = 69, 49%), N (n = 136, 96%), and a combination (U and N) (n = 77, 55%, overlap counted). The majority of U diagnoses were benign prostatic hyperplasia. The majority of N diagnoses were dementia with Lewy bodies, white matter disease (brain); lumbar spondylosis, and diabetes (peripheral disease). We noted triple-disease etiology in 25% (n = 35), increasing with each decade of age (18.2% of sexagenarians, 23.5% of septuagenarians, 39.1% of octogenarians). However, the differences were not significant. CONCLUSION: Our results demonstrate that triple disease for LUTS is the most common in octogenarians, and clinicians thus need to untangle LUTS etiologies to provide appropriate care and management of older adults.

Luxury Perfusion Producing Sensory Aphasia.

We describe the case of an 86-year-old Japanese man who, by luxury perfusion after spontaneous recanalization of the left middle cerebral artery/internal carotid artery, produced acute transient sensory aphasia. This rare phenomenon is thought to be caused by reperfusion brain injury.

Hemichorea Neglect after Stroke.

We report a case of a 74-year-old Japanese woman who, after left thalamic infarction, developed right hemichorea and its neglect. This rare finding was associated with ipsi- and contralateral brain perfusion changes, presumably reflecting de-afferentiation within the brain.

Does Depression Contribute to the Bladder and Bowel Complaint in Parkinson's Disease Patients?

BACKGROUND: The question of whether depression contributes to the bladder and bowel complaint in Parkinson's disease (PD) has not been addressed. OBJECTIVES: We studied bladder, bowel and sexual symptoms in PD patients with/without depression. METHODS: We had 267 referred PD patients: age 68.3 ± 7.7 years, 150 men, 117 women. We divided them into those with/without depression and performed the pelvic function questionnaires including bladder, bowel and sexual items; for example, OABSS, IPSS, and a pelvic organ questionnaire). RESULTS: The patient age, sex ratio, disease duration, Hoehn-Yahr motor grade, and cognitive score were not significantly different between the PD with depression (n = 35, 13.1%) and PD without depression (n = 232, 86.9%) groups. Regarding bladder, bowel and sexual complaints, significant difference was noted in constipation (P = 0.000854) and sensation of residual urine (P = 0.04820) items. CONCLUSIONS: Our PD patients with depression showed significantly more common constipation and sensation of residual urine compared to the patients with PD alone, suggesting that depression contributes to the bladder and bowel complaint in PD patients.

Inner-Ear Symptom May Herald Basilar Artery Occlusion.

A 75-year-old Japanese man suddenly experienced right cochlear and vestibular dysfunction. Basilar artery occlusion and silent right cerebellar infarction were identified 3 days later. These were treated with intravenous ozagrel (an antiplatelet agent) and edaravone, a free-radical scavenger. The patient did not develop cerebello-brainstem signs. His first sign most probably reflected a right labyrinthine artery occlusion that heralded, or occurred together with, the basilar artery occlusion. This case highlights the possibility that a sudden inner ear dysfunction may herald a basilar stroke. Clinicians should therefore initiate appropriate therapy to prevent life-threatening brainstem complications.

Female detrusor underactivity: Two uterine leiomyoma cases.

INTRODUCTION: Female urinary retention is rare. CASE PRESENTATION: Case 1, a 35-year-old nulliparous woman, and case 2, a 47-year-old nulliparous woman, had transient urinary retention. A urodynamics revealed increased bladder sensation in case 1 and detrusor underactivity with a large post-void residual in cases 1 and 2. Both women had a uterine leiomyoma of >10 cm in diameter. Soon after extraction of the tumor, retention episodes disappeared completely in case 1. CONCLUSION: Although rare, uterine leiomyoma should be listed as a cause of female detrusor underactivity.

Urinary retention with occult meningeal reaction: a 'form fruste' meningitis-retention syndrome.

We report the case of a 70-year-old Japanese man who was referred from a local urologist because of acute urinary retention (detrusor underactivity revealed by a urodynamics examination). A neurogenic urinary retention workup failed to reveal the aetiology, but a spinal tap incidentally showed occult meningeal reaction with positive oligoclonal band. The patient had no headache, nausea/vomiting or fever. Considering his clinical laboratory findings, his neural lesions seemed to involve the meninges and spinal cord, suggestive of 'form fruste' meningitis-retention syndrome. When clinicians encounter patients with urinary retention of undetermined aetiology, a spinal tap should be considered.

Lower urinary tract function in frontotemporal lobar degeneration: A preliminary observation.

OBJECTIVE: The urodynamics underlying lower urinary tract (LUT) dysfunction in frontotemporal lobar degeneration (FTLD) has not been reported. Herein, we investigated LUT function in FTLD patients by performing a urodynamics analysis. PATIENTS AND METHODS: We recruited five FTLD patients with LUT symptoms: three men, two women; mean age, 70.4 years; mean disease duration, 3.8 years; mean Hoehn-Yahr grade 1.0. We administered a urinary symptom questionnaire and performed a urodynamics study in each patient. RESULTS: LUT symptoms were observed in all patients. Urinary urgency/frequency (also called overactive bladder, OAB) was noted in all; OAB wet in three (60%) and mild voiding difficulty in two (40%). The urodynamic abnormalities included detrusor overactivity in four (80%), increased bladder sensation in two, large post-void residual in one (comorbid spondylosis), and latent detrusor underactivity in two. None had apparent outlet obstruction or detrusor-sphincter dyssynergia. Sphincter electromyography was normal in the cases studied. CONCLUSION: We observed detrusor overactivity in FTLD patients with LUT symptoms. Although a preliminary observation, this LUT feature, which might reflect the frontal/insular cortex pathology typically associated with FTLD, requires appropriate management and care.

Urodynamic Assessment of Neuronal Intranuclear Inclusion Disease.

Neuronal intranuclear inclusion disease (NIID) is a disease that causes leukoencephalopathy (dementia) and peripheral neuropathy (variable manifestation including bladder dysfunction). This is the first urodynamic report to show that bladder dysfunction in NIID is a combination of detrusor overactivity, decreased bladder sensation, large post-void residual, and neurogenic changes in the sphincter electromyogram. This report will help managing bladder dysfunction in NIID.

Diabetic Neuropathy: Distribution Pattern Revisited.

It is not well known which of the common neuropathic distribution patterns in diabetes might suggest underlying mechanisms. To examine this question, we present data from a nerve conduction study (NCS). Irrespective of symptoms, we enrolled 323 type 2 diabetic patients (206 men, 117 women; mean age 64.1 years [51-79]; duration 12.0 years [5-19]; HbA1C 8.7% [5.1-12.1]; half [n = 142] untreated). NCS was performed for the following patterns: mononeuropathy (unilateral [MNU], bilateral [MNB]), multiple mononeuropathy (MMN), and polyneuropathy (PN). In 266 patients, we performed atherosclerosis tests: cardio-ankle vascular stiffness index (CAVI) and carotid ultrasonography. Neuropathy was observed in 235, and in 88 it was not observed; the latter then served as the control group. The most common pattern was MMN (26%), followed by MNB (18%), PN (16%), and MNU (12%). A combination of demyelination and axonal damage was revealed. Longer duration of diabetes compared with controls (8.6 years) was associated with MNB (12.5 years), MMN (14.8 years), and PN (17.4 years) (p < 0.05). HbA1C was associated with PN (p < 0.05). Atherosclerosis risks were associated with MNB, MMN, and PN (p < 0.05). Our study results indicated that (multiple) mononeuropathy is the most common distribution pattern in diabetes.

Probable Creutzfeldt-Jakob Disease Presenting Dementia and Urinary Retention.

We describe the case of an 80-year-old woman with probable Creutzfeldt-Jakob disease (CJD) presenting dementia and urinary retention. Although the number of patients previously examined, including ours, is small for conclusion, provided that other etiologies of urinary retention are carefully excluded, urinary retention seems to become a feature in CJD, presumably reflecting spinal cord pathology in CJD. Physicians are advised to evaluate pelvic floor function in CJD particularly by checking post-void residuals.

Possible "Premotor" Multiple System Atrophy-Cerebellar Form.

We report the case of a 52-year-old Japanese man who, while he had no cerebellar ataxia or parkinsonism, was revealed to have silent cerebellar hypoperfusion/mild cerebellar atrophy and sacral autonomic disorder. His sacral autonomic disorder was urinary retention without marked prostate hyperplasia. Urodynamics-sphincter electromyography revealed detrusor hyperactivity with impaired contraction and neurogenic changes of the sphincter motor unit potentials. Although he did not have a motor disorder, these features suggested possible multiple system atrophy-cerebellar (MSA-C) form. The present case report suggests that neuroimaging helps in diagnosing "premotor" MSA-C form in situ.
