Posttraumatic functional movement disorders and litigation.

The concept of functional movement disorders has evolved considerably over the past few decades. More specifically, the views on the relation with psychological stressors or personality disorders have substantially changed, emphasizing a shift from the previously dominant dualistic scheme. This evolution is reflected in adaptations to diagnostic criteria and management approaches. Functional movement disorders which arise in a close temporal relationship with a peripheral trauma are specifically challenging with respect to diagnosis and treatment, but similar considerations seem to apply. The relationship of functional disorders with trauma appears to be much closer than is often thought. Clinical and pathophysiological research has identified shared factors underlying functional posttraumatic as well as primary movement disorders. These evolving insights impact on discussions in terms of litigation for compensation after trauma. The literature is reviewed and the consequences for argumentation in litigation are outlined, including ethical and legal considerations. Finally, we formulate a number of recommendations.

Subthalamic nucleus activity in the processing of body and mental action verbs in people with Parkinson's disease.

Local field potentials evoked by body action and mental action verbs were recorded in the subthalamic nucleus (STN) of 18 patients with Parkinson's disease through the electrodes implanted for deep brain stimulation. Compared with the medication on-condition, the medication off-condition showed a difference in activity in the early time segments, mainly in the right STN, with larger amplitudes for body action verbs. In the on-condition a similar pattern was detected in the left STN. These patterns of early differences in activity evoked by different types of verbs might indicate the potential of the STN to rapidly detect relevant behavioural clues in verbal content and to integrate these in subsequent cortico-subcortical interactions. In addition, these lateralizations allow speculations about shifts in processing activity correlating with dopaminergic denervation. Whether this detection relies on phonological, semantic or grammatical clues remains an open question.

Selective use of cystogram following segmental bowel resection in patients with enterovesical fistula.

AIM: Patients undergoing resectional surgery for enterovesical fistulas generally have an indwelling urinary catheter postoperatively to prevent a recurrent fistula. The aim of this study was to assess the role of a cystogram as part of the postoperative follow-up of such surgery, when it should be performed and for how long the bladder should be drained after surgery. METHOD: A retrospective single-centre study of all patients undergoing ileocaecal or sigmoid resection for surgery for enterovesical fistula with the primary end-point of recurrent urinary fistula. RESULTS: Between 1994 and 2015, 46 patients (23 male; mean age 55.4 ± 18.3 years) underwent surgery [23 (50%) for diverticular disease, 16 (34.8%) for Crohn's disease, five (10.9%) for malignancy and two (4.3%) for previous radiotherapy]. Closure of the bladder fistula was by simple suture in 21 (46%) patients and with an omental pedicle in 16 (36%). Overall median duration of urinary drainage was 10.5 [interquartile range (IQR): 7.3-14.0] days. A postoperative cystogram was performed in 26 (57%) patients after a median of 10.0 (IQR: 8.0-13.0) days. This demonstrated persistent leakage in three patients, of whom two had undergone surgical closure of the bladder. This group required prolonged drainage (7, 19 and 40 days). One patient who had undergone surgery following radiotherapy for urothelial cancer developed a recurrent malignant fistula at 9 months, even though the postoperative cystogram had been negative. CONCLUSION: This study suggests that a routine postoperative cystogram after surgery for enterovesical fistula may not be necessary for all patients if the bladder is drained for 1-2 weeks after bowel resection.

Computed tomography determined femoral torsion is not accurate.

INTRODUCTION: Computed tomography (CT) is considered the method of choice for detecting rotational malalignment of the femur. However, it is unclear how reliable the method is, and what the causes are of potential inaccuracies. MATERIALS AND METHODS: To address these issues three observers measured the CT images of the femur of 76 patients on two separate occasions. The images were made during follow-up of a unilateral femoral shaft fractures. Rotational malalignment was determined by comparing the torsion angle of the injured to the noninjured leg. RESULTS: The pooled intraobserver variance was 3.9 degrees and interobserver variance 4.1 degrees. Of the two measurements of one observer 95% were up to 10.8 degrees different, and between observers 95% of the measurements were up to 15.6 degrees different. CONCLUSIONS: CT measurements of rotational malalignment of the femur are not accurate. This is due principally to the difficulty in defining a line through the axis of the femoral neck. The accuracy can be improved by taking the average of two measurements.
