RESUMO
BACKGROUND: The clinical course of motor deficits from lumbosacral radiculopathy appears to improve with or without surgery. Strength measurements have been confined to manual muscle testing (MMT) and have not been extensively followed and quantified in prior studies. OBJECTIVE: To determine if motor weakness and patient-reported outcomes related to lumbosacral radiculopathy improve without surgical intervention over the course of 12 months. DESIGN: Prospective observational cohort. SETTING: Outpatient academic spine practice. PARTICIPANTS: Adults with acute radicular weakness due to disk herniation. METHODS: Forty patients with radiculopathy and strength deficit were followed over a 12-month period. Objective strength and performance tests as well as survey-based measurements were collected at baseline and then every 3 months. Patients underwent comprehensive pain management and rehabilitation and/or surgical approaches as determined in coordination with the treating specialist. This study was approved by the institutional review board of Colorado. MAIN OUTCOME MEASUREMENTS: Testing of strength was through MMT, handheld dynamometer, and performance-based testing. Furthermore, visual analog scale, modified Oswestry Disability Index, and 36-Item Short Form Health Survey (SF-36) were used to measure pain and disability outcomes. RESULTS: Of the 40 patients, 33 (82.5%) did not have surgery; 7 (17.5%) had surgery. Twenty-four of the 33 patients (60%) did not undergo surgery and were followed for 12 months (Comprehensive Pain Management and Rehabilitation, Complete [CPM&R-C]), and 9 (22%) did not have surgery and lacked at least one follow-up evaluation (Comprehensive Pain Management and Rehabilitation, Incomplete [CPM&R-I]). No statistically significant differences were found on baseline measures of strength deficits and SF-36 domains between the CPM&R-C, Surgery, and CPM&R-I groups. Pain and disability scores in the Surgery group were significantly higher than in the CPM&R-C at baseline. There were statistically significant improvements in all areas of strength, pain, and function when comparing measurements at the 12-month follow-up to baseline in the CPM&R-C group. CONCLUSIONS: Individuals with motor deficits due to lumbosacral radiculopathy improve over time regardless of treatment choice. Most did not choose surgery, and almost all of these patients regained full strength at 1 year. Strength recovery typically occurred in the first 3 months, but there was ongoing recovery over the course of a year. LEVEL OF EVIDENCE: II.

PURPOSE: To compare the clinical presentation of prostatic abscess and treatment outcome in two different time frames with regards to etiologies, co-morbid factors and the impact of multidrug resistant organism. MATERIALS AND METHODS: We retrospectively assessed the charts of 48 patients with the diagnosis of prostatic abscess from 1991 to 2005. The period was divided arbitrarily into two different time frames; phase I (1991-1997) and phase II (1998-2005). Factors analyzed included presenting features, predisposing factors, imaging, bacteriological and antibiotic susceptibility profile, treatment and its outcome. RESULTS: The mean patient age in phase I (n = 18) and phase II (n = 30) were 59.22 +/- 11.02 yrs and 49.14 +/- 15.67 respectively (p = 0.013). Diabetes mellitus was most common predisposing factor in both phases. Eleven patients in phase II had no co-morbid factor, of which nine were in the younger age group (22 - 44 years). Of these eleven patients, five presented with pyrexia of unknown origin and had no lower urinary tract symptoms LUTS. Two patients with HIV had tuberculous prostatic abscess along with cryptococcal abscess in one in phase II. Two patients had melioidotic prostatic abscess in phase II. The organisms cultured were predominantly susceptible to first line antibiotics in phase I whereas second or third line in phase II. CONCLUSION: The incidence of prostatic abscess is increasing in younger patients without co-morbid factors. The bacteriological profile remained generally unchanged, but recently multi drug resistant organisms have emerged. A worrying trend of HIV infection with tuberculous prostatic abscess and other rare organism is also emerging.
