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

Management of lower urinary tract symptoms in Parkinsonian disorders

INTRODUCTION

The aim of the study was to present a narrative review of the literature on the management of lower urinary tract symptoms (LUTS) in patients presenting Parkinsonian disorders (PD).

MATERIAL AND METHODS

We carried out a literature search in PubMed and Embase database, without time restriction. We used keywords and free-text words around "Parkinsonian disorders" AND "lower urinary tracts symptoms" without language restriction. We focused mainly on papers less than 10 years old. We included all studies evaluating LUTS in patients with PD.

RESULTS

For the diagnostic management, authors emphasized the importance of differentiating Parkinson's disease with symptoms of bladder overactivity from multiple system atrophy with symptoms of bladder hypoactivity. Urodynamic evaluation was noted as the key element of diagnostic management. The therapeutic management proposed was symptomatic, based on functional urology techniques for the treatment of LUTS, both with drugs (especially anticholinergics) or surgery (intradetrusor injections of botulinum toxin, neuromodulation). Moreover, it was pointed out that it is always necessary to take into account the existence of a possible associated uropathy (prostate adenoma or pelvic prolapse).

CONCLUSION

Urodynamic evaluation is the cornerstone of diagnostic management of LUTS in patients with PD. Therapeutic management is above all symptomatic and must be done in a collegial way involving the urologist, neurologist, gynecologist, and physical medicine and rehabilitation physician.

Cancer in pathologically confirmed multiple system atrophy

PURPOSE

The aim of this study was to assess whether cancer occurs with increased frequency in multiple system atrophy (MSA). The pathological hallmark of MSA is glial cytoplasmic inclusions containing aggregated α-synuclein, and the related protein γ-synuclein correlates with invasive cancer. We investigated whether these two disorders are associated clinically.

METHODS

Medical records of 320 patients with pathologically confirmed MSA seen between 1998 and 2022 were reviewed. After excluding those with insufficient medical histories, the remaining 269 and an equal number of controls matched for age and sex were queried for personal and family histories of cancer recorded on standardized questionnaires and in clinical histories. Additionally, age-adjusted rates of breast cancer were compared with US population incidence data.

RESULTS

Of 269 cases in each group, 37 with MSA versus 45 of controls had a personal history of cancer. Reported cases of cancer in parents were 97 versus 104 and in siblings 31 versus 44 for MSA and controls, respectively. Of 134 female cases in each group, 14 MSA versus 10 controls had a personal history of breast cancer. The age-adjusted rate of breast cancer in MSA was 0.83%, as compared with 0.67% in controls and 2.0% in the US population. All comparisons were nonsignificant.

CONCLUSION

The evidence from this retrospective cohort found no significant clinical association of MSA with breast cancer or other cancers. These results do not exclude the possibility that knowledge about synuclein pathology at the molecular level in cancer may lead to future discoveries and potential therapeutic targets for MSA.
