Impulse control disorder-linked hypersexuality complicated by disseminated gonococcal infection in a patient with Parkinson's disease

Exploring brain changes of impulse control disorders in Parkinson's disease: An ALE study

Background

Previous neuroimaging studies reported inconsistent results for comparison between Parkinson's disease (PD) with impulse control disorder (PD-ICD) and without ICD (PD-no ICD).

Methods

A search was performed in databases (PubMed and Web of Science) to identify studies published before May 2022. An anatomic likelihood estimation (ALE) method study was made for neuroimaging studies in PD-ICD.

Results

The study included 20 studies (including 341 PD-ICD and 437 PD-no ICD). PD-ICD patients showed significant cortical thinning in the right inferior frontal gyrus (IFG), the right middle frontal gyrus (MFG), the left superior frontal gyrus (SFG), the right precentral gyrus (PCG) and the left cingulate gyrus (CG), compared to PD-no ICD patients. The ALE study showed reduced resting-state brain activation in the right IFG, the right PCG, the left insula and the right transverse temporal gyrus (TTG) in PD-ICD, compared to PD-no ICD patients. In addition, PD-ICD showed increased resting-state brain activation in the right caudate, the bilateral insula and the left orbital gyrus (OG), compared to PD-no ICD patients. The study indicated reduced task-related brain activation in the right caudate, the right MFG, the right lentiform nucleus (LN) and the right precuneus (PCUN) in PD-ICD, compared to PD-no ICD patients. The study showed increased task-related brain activation in the left inferior parietal lobule (IPL), the right medial frontal gyrus, the right caudate and the right PCG in PD-ICD, compared to PD-no ICD patients.

Conclusions

The present ALE analysis has confirmed that brain changes in frontal, temporal and basal ganglia regions are among the most frequently reported regions in PD-ICD. Deficits in these regions could play a role in diagnosis of PD-ICD.

Impulse Control Disorders in Parkinson's Disease: Epidemiology, Pathogenesis and Therapeutic Strategies

Impulse control disorders (ICDs) in Parkinson's disease (PD) are aberrant behavior such as pathological gambling, hypersexuality, binge eating, and compulsive buying, which typically occur as a result of dopaminergic therapy. Numerous studies have focused on the broad spectrum of ICDs-related behaviors and their tremendous impact on patients and their family members. Recent advances have improved our understanding of ICDs. In this review, we discuss the epidemiology, pathogenesis and treatment of ICDs in the setting of PD.

Septic arthritis due to Neisseria gonorrhoea in Western Australia

OBJECTIVE

To investigate the frequency, risk factors and long-term outcome of gonococcal arthritis in Western Australia (WA).

METHODS

A population-based data linkage study of patients with a hospital-based diagnosis of gonococcal arthritis (GA) in WA between 1990-2014. Demographics, standardised incidence rates (IR) per million and comorbidity accrued before (lookback 186 months ,IQR 86-267) and after the index hospital contact for GA (follow-up 100 months, IQR 60-209). are presented as frequency (%), median (interquartile range) or rates /1,000 months.

RESULTS

In total 98 patients were diagnosed with GA. The annual incidence of GA increased from 1.35 to 2.10 per million between 1990 and 2014, but the rate of GA complicating all gonococcal infections was stable around 0.25%. Female patients with GA (54%, n=53/98) were younger (24 vs 38 years), and more frequently identified as Indigenous (88% vs 49%) than male patients (46%, n=45/98) (p=0.002). Female patients had higher rates of prior infections (15.5 vs 8.1 per 1,000 months, p=0.002) and diabetes mellitus (15.9% vs 2.5%, p=0.03) and a longer hospital stay (10 vs 8 days, p=0.02). GA recurrence rate during follow-up was low (2%), but a broad range of comorbidities developed contributing to a 14% crude death rate.

CONCLUSIONS

GA stably complicates 0.25% of gonococcal infections in WA with young Indigenous females and middle-aged non-Indigenous males most affected. Prior infectious disease and diabetes mellitus are potential risk factors for GA in females. GA recurs rarely, but its development reflects a high risk of morbidity and mortality over the following ten years. This article is protected by copyright. All rights reserved.
