METHODS: This is a retrospective study. Forty-two eyes of 26 patients with primary congenital glaucoma were enrolled, Intraocular pressure (lOP), corneal diameter (mm) and cup/disc (C/D) were measured before and after the surgery respectively. Follow-up period was 30mo. RESULTS: The mean preoperative lOP was 30.6:1:7.35 mm Hg. Of the 42 eyes, 2 eyes were required conversion to trabeculectomy for the absence of Schlemm's canal. Of remained 40 eyes, 38 eyes (95%) achieved successful lOP control. The average postoperative lOP was 11.69±4.18 mm Hg at 12mo. The mean reduction was 18.91 mm Hg (P〈0.00Ol). Eighteen (75%) eyes presented a reduction in corneal diameter, and 25 (62.5%) eyes presented a C/D ratio reversal after the surgery. There was no serious complication in any patients over the follow-up period. CONCLUSION: Viscocanalostomy combined with trabeculotomy and mitomycin C is useful in the management of primary congenital glaucoma,展开更多

PD is classically characterized by motor features, although patients may also experience non-motor symptoms. Sleep disturbances, such as rapid eye movement (REM) behavior disorder (RBD), are common in patients with PD and may precede onset of PD. Methods: Data was collected on patients with PD (358 subjects)in a movement disorders clinic at a safety net hospital. In this retrospective database analysis, the association of PD complications with age of onset was evaluated using chi-square tests and logistic regression. Results: Of the PD complications analyzed, there was a significant difference in sleep disturbances by age. Among the 358 PD patients, 120 individuals (33.5%) had information regarding the presence or absence of sleep disturbances. There was a significant difference between the early (onset < 50) and later onset (≥50) groups (p = 0.03) with the odds of having a sleep disorder for the early group 1.6 times that of the late group. Those subjects with siblings who also had PD had 2.0 times the odds of having a sleep disorder compared those without (p = 0.02). Conclusion: Non-motor symptoms such as sleep disorders are a useful predictor of early onset PD. Genetic components of PD impact both motor and non-motor aspects of the disease.展开更多

The aim of this study was to identify whether RBD could alleviate OSA severity in PD patients and its effect on cognitive impairment.Methods:From February 2014 to May 2017, we recruited 174 PD patients from the Second Affiliated Hospital of Soochow University, all of whom underwent polysomnography (PSG). We collected clinical data, PSG results, and compared information between patients with and without RBD or OSA by analysis of covariance. We also investigated the effect of these sleep disorders on cognitive impairment using linear regression.Results:We grouped participants as follows: PD only (n = 53), PD + OSA (n = 29), PD + RBD (n = 61), and PD + RBD + OSA (n = 31). Minimum oxygen saturation (SaO2) during whole sleep and in REM sleep was higher in PD + RBD + OSA patients than that in PD + OSA patients. PD + RBD patients had worse Mini-Mental Status Examination and Montreal Cognitive Assessment (MoCA) scores than those in the PD group (P 〈 0.001), especially in visuospatial/executive, attention, and memory functions. The PD + OSA group performed worse than the PD group in the delayed recall domain. After adjusting for age, sex, body mass index, education, disease severity, and other sleep disorders, MoCA was negatively associated with OSA (β = ?0.736, P = 0.043) and RBD (β = ?2.575, P 〈 0.001). The severity of RBD (tonic/phasic electromyography activity) and OSA (apnea-hypopnea index/oxygen desaturation index/minimum SaO2) were also associated with MoCA. The adjusted β values of RBD-related parameters were higher than that for OSA.Conclusions:We found that RBD alleviated OSA severity; however, RBD and OSA together exacerbated PD cognitive impairment. Further studies are needed to evaluate whether OSA treatment can improve cognition in PD.展开更多

The mechanism underlying RBD is unclear. Several prospective studies have reported that specific non-motor symptoms predict a conversion risk of developing a neurodegenerative disease, including olfactory dysfunction, abnormal color vision, autonomic dysfunction, excessive daytime sleepiness, depression, and cognitive impairment. Parkinson's disease (PD) with RBD exhibits clinical heterogeneity with respect to motor and non-motor symptoms compared with PD without RBD. In this review, we describe the main clinical and pathogenic features of RBD, focusing on its association with other non-motor symptoms of parkinsonism.展开更多
