RESUMO
Voiding cystourethrography (VCUG) is a widely accepted radiographic imaging technique that has been traditionally used for identifying vesicoureteral reflux in children. Given the simultaneous evaluation of the lower urinary tract that is afforded by VCUG, many common and uncommon abnormalities of the ureters, bladder and urethra can also be elucidated. Knowledge of the appearance of these urological entities may facilitate their proper identification.

PURPOSE: Our purpose was to assess the short-term results and describe the technique of arthroscopic repair of irreparable rotator cuff tears by use of a GraftJacket allograft (Wright Medical Technology, Arlington, TN). METHODS: Between March 2003 and February 2004, 16 patients with massive, contracted, immobile rotator cuff tears were treated with arthroscopic placement of a GraftJacket allograft by a single surgeon. Patients were followed up for 1 to 2 years. All were evaluated preoperatively and postoperatively by use of the modified University of California, Los Angeles scoring system, Constant score, and Simple Shoulder Test. Magnetic resonance imaging was performed postoperatively at 3 months and 1 year. RESULTS: At a mean follow-up of 26.8 months (range, 12 to 38 months), 15 of 16 patients were satisfied with the procedure. The mean University of California, Los Angeles score increased from 18.4 preoperatively to 30.4 postoperatively (P = .0001). The Constant score increased from 53.8 to 84.0 (P = .0001). Statistically significant improvements were seen in pain, forward flexion, and external rotation strength. Thirteen patients had full incorporation of the graft into the native tissue as documented on magnetic resonance imaging. There were no complications in this cohort of patients. CONCLUSIONS: Our study supports GraftJacket allograft as a viable solution for surgical salvage in select cases of massive, irreparable rotator cuff pathology. This treatment option may provide patients with decreased pain and increased function despite a previously irreparable rotator cuff tear. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

BACKGROUND: High-frequency percussive ventilation (HFPV), a hybrid of conventional mechanical ventilation and high-frequency oscillatory ventilation, has been used to salvage patients with persistent hypoxemia on conventional mechanical ventilation. We hypothesized that oxygenation would improve in injured patients with severe hypoxemia who were converted to HFPV after initial management with conventional ventilation. METHODS: Chart review identified patients with acute respiratory distress syndrome (ARDS) managed with HFPV. Oxygenation parameters (oxygenation index, OI; Pao(2)/Fio(2) ratio, P/F) and mean airway pressures (mPaw) were recorded at baseline and at 1 to 4, 8 to 12, and 12 to 24 hours after initiation of HFPV. Values at baseline and each time point after conversion to HFPV were compared by using analysis of variance or Kruskal-Wallis tests. RESULTS: Twelve patients, over 24 months, were reviewed. Baseline measurements were OI: 42.2 +/- 33, P/F: 70 +/- 31, (median +/- interquartile range), and mPaw: 29 +/- 8 (mean +/- standard deviation) cm H(2)O. After initiation of HFPV, mPaw did not differ from baseline. There was an improvement in OI (P = .01) from baseline at 12 to 24 hours after initiation of HFPV and in P/F at 12 to 24 hours (P = .002) and 8 to 12 hours (P = .001) after initiation of HFPV. CONCLUSIONS: HFPV may improve oxygenation in patients with ARDS without a concomitant increase in mPaw. A randomized trial of HFPV versus conventional ventilation in trauma patients is needed.

A device capable of detecting seizures and alerting caregivers would be a major advance for epilepsy management, and could be used to guide early intervention and prevent seizure-related injuries. The objective of this work was to evaluate a seizure advisory system (SAS) that alerts caregivers of seizures in canines with naturally occurring epilepsy. Four dogs with epilepsy were implanted with a SAS that wirelessly transmits continuous intracranial EEG (iEEG) to an external device embedded with a seizure detection algorithm and the capability to alert caregivers. In this study a veterinarian was alerted by automated text message if prolonged or repetitive seizures occurred, and a rescue therapy protocol was implemented. The performance of the SAS caregiver alert was evaluated over the course of 8 weeks. Following discontinuation of antiepileptic drugs, the dogs experienced spontaneous unprovoked partial seizures that secondarily generalized. Three prolonged or repetitive seizure episodes occurred in 2 of the dogs. On each occasion, the SAS caregiver alert successfully alerted an on call veterinarian who confirmed the seizure activity via remote video-monitoring. A rescue medication was then administered and the seizures were aborted. This study demonstrates the feasibility of a SAS to alert caregivers to the occurrence of prolonged or repetitive seizures and enables rescue medications to be delivered in a timely manner. The SAS may improve the management of human epilepsy by alerting caregivers of seizures, enabling early interventions, and potentially improving outcomes and quality of life of patients and caregivers.

OBJECTIVE: To summarize clinical information and assessment techniques relevant to respiratory therapists caring for adult patients on high-frequency oscillatory ventilation (HFOV). DATA SOURCE: Review of observational studies, controlled trials, case reports, institutional experience, and hospital HFOV guidelines for adult patients. DATA SUMMARY: Respiratory therapists require unique physical assessment skills and knowledge in managing patients on HFOV. Respiratory therapy procedures relevant to HFOV include setting endotracheal tube cuff leaks, performing lung recruiting maneuvers, endotracheal suctioning, and monitoring ventilator parameters. Respiratory therapists serve as essential team members in the creation and implementation of written HFOV guidelines (e.g., algorithms) to optimize patient care. CONCLUSION: Respiratory therapy assessment and procedural skills are essential in providing optimal care to adult patients on HFOV.
