Background: There is controversy regarding the effectiveness of brachial plexus reconstruction for elbow function in older patients, as reported outcomes are generally poor. The purpose of this study was to evaluate elbow function outcomes in patients older than 50. Methods: Fifty-eight patients older than 50 years underwent nerve grafting, transfers, or free functioning muscle transfer to improve elbow function after traumatic brachial plexus injury. Patients were evaluated preoperatively and postoperatively for elbow flexion strength and range of motion; Disabilities of the Arm, Shoulder and Hand scores; pain; concomitant trauma; severity of trauma; and type of reconstruction. Results: The average age of the patients was 57.8 years, and the average follow-up was 24.0 months. The average modified British Medical Research Council elbow flexion grade improved significantly from 0.26 to 2.63. Thirty-three patients (60 percent) achieved functional flexion greater than or equal to M3 postoperatively, compared to zero patients preoperatively. There was no correlation between age and modified British Medical Research Council grade. Active elbow range of motion improved significantly postoperatively, with no effect of age on flexion motion. More patients achieved greater than or equal to M3 flexion with nerve transfers (69 percent) compared to free functioning muscle transfer (43 percent). Patients had worse outcomes with high-energy injuries. The mean Disabilities of the Arm, Shoulder and Hand score decreased from 51.5 to 49.6 postoperatively, and the average pain score decreased from 5.0 to 4.3. Conclusion: Brachial plexus reconstruction for elbow function in patients older than 50 can yield useful flexion. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Background The utility of early postoperative ultrasound measurements in predicting arteriovenous fistula (AVF) clinical maturation is uncertain. Methods We investigated the relationships of ultrasound parameters with AVF clinical maturation in newly created AVF, measured at 1 day and 2 and 6 weeks, in 602 participants of a multicenter, observational cohort study. A backward elimination algorithm identified ultrasound measurements that independently predicted unassisted and overall AVF maturation. Candidate variables included AVF blood flow, diameter, and depth, upper arm arterial diameter, presence of stenosis, presence of accessory veins, seven case-mix factors (age, sex, black race, AVF location, diabetes, dialysis status, and body mass index), and clinical center. We evaluated the accuracy of the resulting models for clinical prediction. Results At each ultrasound measurement time, AVF blood flow, diameter, and depth each predicted in a statistically significant manner both unassisted and overall clinical maturation. Moreover, neither the remaining ultrasound parameters nor case-mix factors were associated with clinical AVF maturation after accounting for blood flow, diameter, and depth, although maturation probabilities differed among clinical centers before and after accounting for these parameters. The crossvalidated area under the receiver operating characteristic curve for models constructed using these three ultrasound parameters was 0.69, 0.74, and 0.79 at 1 day and 2 and 6 weeks, respectively, for unassisted AVF clinical maturation and 0.69, 0.71, and 0.76, respectively, for overall AVF maturation. Conclusions AVF blood flow, diameter, and depth moderately predicted unassisted and overall AVF clinical maturation. The other factors considered did not further improve AVF maturation prediction.

Background: Establishing continuity of the cutaneous roll is critical to cleft lip repair. Unfortunately, this landmark can be difficult to appreciate depending on the patient’s skin tone, surgical lighting, or preexisting scar. Solution: When applied to the lip, dilute povidone-iodine solution beads off the cutaneous roll and dry vermilion, clearly defining these structures. What We Do: We use dilute povidone-iodine solution not only to prep the lip but to delineate landmarks critical to cleft lip repair.

Summary Background Irritable bowel syndrome ( IBS ) is a chronic functional bowel disorder. Disturbances in the gastrointestinal microbiome may be involved in its aetiology. Aim To perform a systematic review and meta‐analysis to examine the efficacy of prebiotics, probiotics, synbiotics and antibiotics in IBS . Methods MEDLINE , EMBASE , and the Cochrane Controlled Trials Register were searched (up to July 2017). Randomised controlled trials ( RCT s) recruiting adults with IBS , comparing prebiotics, probiotics, synbiotics or antibiotics with placebo or no therapy were eligible. Dichotomous symptom data were pooled to obtain a relative risk ( RR ) of remaining symptomatic after therapy, with a 95% confidence interval ( CI ). Continuous data were pooled using a standardised mean difference with a 95% CI . Results The search identified 4017 citations. Data for prebiotics and synbiotics were sparse. Fifty‐three RCT s of probiotics, involving 5545 patients, were eligible. Particular combinations of probiotics, or specific species and strains, appeared to have beneficial effects on global IBS symptoms and abdominal pain, but it was not possible to draw definitive conclusions about their efficacy. There were five trials of similar design that used rifaximin in non‐constipated IBS patients, which was more effective than placebo ( RR of symptoms persisting = 0.84; 95% CI 0.79‐0.90). Adverse events were no more common with probiotics or antibiotics. Conclusions Which particular combination, species or strains of probiotics are effective for IBS remains, for the most part, unclear. Rifaximin has modest efficacy in improving symptoms in non‐constipated IBS .

Arthroscopic dorsal wrist ganglionectomy is demonstrably a safe procedure with recurrence rates comparable to open surgery. We present a patient with wrist pain following arthroscopic ganglion excision. MRI and arthroscopic findings showed a large dorsal capsular defect, synovial fistula to the fourth extensor compartment, and dorsal radiocarpal ligament resection. Ligament reconstruction and capsular imbrication resolved her symptoms. We postulate that this complication resulted from a large capsular resection. Because we feel that it can be difficult to judge the size of the debridement through an arthroscope, the need for adequate capsular resection in dorsal wrist ganglionectomy needs to be balanced by consideration of potential complications from more aggressive capsular debridement, and thus we feel that capsular resection should be limited to no more than 1 cm2.

AbstractBackgroundMedication discrepancies are common between transitions in healthcare and are associated with higher healthcare utilisation and hospital readmission following discharge. Medication reconciliation is a key intervention to reduce medication list discrepancy. The transition between discharge and first outpatient appointment is critical for patient recovery. The proportion of medication discrepancies during this interval is not well characterised.AimThe aim of this study was to evaluate the accuracy of patients’ medication list between discharge from hospital or emergency department to first outpatient follow‐up with their primary care physician.MethodsA cross‐sectional observational study was performed between November 2015 and May 2016. A 10‐question survey was designed to identify potential areas of inaccuracies in the medication lists.ResultsIn all, 106 patients completed the survey, of whom 67.9% (n = 72) had complete data. Eighty per cent of patients (n = 85) had a provider review their medication list prior to discharge. At the time of follow‐up, 22.6% (n = 28) were not taking the listed medications; of this cohort, 35% (n = 8) had a physician instruct them to stop taking medication. Six per cent of patients (n = 6) reported incorrect medication doses.ConclusionMedication discrepancies occur in the transition from hospital discharge to first follow‐up. This poses a threat to patient safety. A standardised process of medication review is critical to prevent such errors.
