Cessation of prophylactic antibiotics for managing persistent vesicoureteral reflux.

PURPOSE: We reviewed our experience with patients with vesicoureteral reflux treated off prophylactic antibiotics. MATERIALS AND METHODS: We retrospectively reviewed the records of patients with vesicoureteral reflux treated off prophylactic antibiotics, noting the intervals on and off antibiotics, urinary tract infection, signs and symptoms associated with urinary tract infection, and renal ultrasound and dimercapto-succinic acid scan findings. RESULTS: We identified 196 patients with vesicoureteral reflux treated off prophylactic antibiotics, including 122 who were infection-free while on and 124 who had no urinary tract infection while off prophylactic antibiotics. The infection rate on and off prophylactics was 0.29 and 0.24 urinary tract infections per patient per year, respectively. New scars were identified in 5 patients while on prophylactics and in 7 after antibiotics were discontinued. Comparing different subgroups off prophylactic antibiotics showed that children who presented with scarring had statistically fewer new scars than those with normal initial dimercapto-succinic acid imaging (p <0.043). Girls had significantly more urinary tract infections than boys while off prophylactics (p <0.01) despite the older age at antibiotic cessation. However, after infection occurred while off prophylactic antibiotics, new renal scars developed at about the same rate in boys and girls. Because most patients did not have a urinary tract infection while off prophylactic antibiotics, new renal scars developed in only 2.2% of all boys and 4% of all girls. CONCLUSIONS: Our findings imply that discontinuing antibiotics is reasonable and safe in patients in whom vesicoureteral reflux fails to resolve.

Characteristics of AMD patients with low vision receiving visual rehabilitation.

The purpose of this retrospective study done on 255 AMD patients evaluated at a low vision rehabilitation service was: 1) to describe the visual function characteristics (VFCs) of AMD patients presenting to visual rehabilitation, 2) to document changes in these VFCs between initial and follow-up rehabilitation visits, and 3) to investigate the relationship of the VFCs found at rehabilitation intake to the length of time between initial diagnosis and initial rehabilitation visit. Standard clinical testing (visual acuity and contrast sensitivity) as well as Scanning Laser Ophthalmoscope (SLO) visual function testing were performed to determine visual function including: 1) macular perimetry for scotoma boundary mapping and 2) PRL (preferred retinal locus) location and abilities in fixation, saccadic, and pursuit eye movements. The difference between the first and second visit VFCs were compared to the length of time between visits for 44 of the 255 patients returning for a second visit 0.5 to 4.5 years later. Finally, the initial date of AMD diagnosis was found for 51 of the 255 patients to analyze VFCs as a function of the time duration between diagnosis and the intake to the rehabilitation. Most VFCs had a wide range of results at initial intake to rehabilitation, while all patients had significant visual impairment by 24 months after initial diagnosis. The majority of low vision patients with AMD have bilateral central scotomas with the corresponding visual function and ADL problems that can often be overcome with visual rehabilitation.

Significance of neutrophils in cerebrospinal fluid samples processed by cytocentrifugation.

We reviewed medical records of 155 pediatric patients whose cerebrospinal fluid (CSF) samples contained an increased proportion of neutrophils when processed by cytocentrifugation, despite normal CSF total white blood cell count. It was determined that these CSF findings occurred more commonly in patients with bacteremia, peripheral leukocytosis, and increased numbers of red blood cells in the CSF. Pulmonary infiltrates in infants and otitis media in children were also significantly associated. Cytocentrifugation allows the identification of neutrophils in the CSF, even in the absence of central nervous system infection. Infants and children with more than 10 per cent neutrophils in CSF require evaluations for focal and bacteremic infections.
