Association between nocturia and anxiety in Parkinson's disease.

OBJECTIVE: The objective of the study was to determine whether there exists any relationship between nocturia and anxiety in patients with Parkinson's disease (PD). Although the exact cause of anxiety and nocturia in PD is unknown, we hypothesized that there is a relationship between these two PD symptoms. Anxiety may exacerbate nocturia or an opposite relationship may be present in which nocturia may result in heightened levels of anxiety. METHODS: Our study consisted of 314 PD patients, selected at random, and divided into groups based on the presence or absence of anxiety and nocturia. The occurrence of anxiety and nocturia was studied individually and collectively within these groups. RESULTS: The study found a significant association between anxiety and nocturia primarily driven by all PD patients (P < 0.0001), with greater significance found for the male patients (P < 0.0001) than female patients (P = 0.021). DISCUSSION: Based on these findings, we can conclude that anxiety and nocturia are not entirely independent symptoms in all PD patients. Thus, addressing anxiety may improve nocturia in PD or vice versa.

Laparoscopic repair of external iliac-artery transection during laparoscopic radical prostatectomy.

BACKGROUND AND PURPOSE: Vascular injuries are the most common complication of pelvic lymph-node dissection. We report a case of total division of the external iliac artery and its immediate laparoscopic repair. METHODS: A 70-year-old man with a prostatic adenocarcinoma (Gleason Score 6) and serum prostate specific antigen concentration of 20 ng/mL had inadvertent external iliac-artery transection during pelvic lymphnode dissection secondary to the abnormal course and anatomy of the artery. Immediate laparoscopic repair was accomplished with a two-needle single-knot technique as is routinely used for the vesicourethral anastomosis. Thereafter, laparoscopic radical prostatectomy was completed. RESULTS: The reconstruction time was 37 minutes. There was no significant blood loss. There were no further intraoperative complications. Postrepair, the femoral pulse was intact, and follow-up duplex color ultrasonography showed good flow. The patient was disharged home on day 7, ambulant and asymptomatic. CONCLUSION: In controlled cicumstances, laparoscopic repair of external iliac-artery transection is feasible and represents a safe alternative to open surgery.
