Degenerative Spinal Disease

Symptomatic degenerative spinal disease is a serious medical condition that affects many individuals. Modern neuroimaging modalities, the development of new medications, and advances in operative and nonoperative treatments have all contributed to improved outcomes. Unfortunately, there remain a significant number of patients in whom primary therapy either fails or new or recurrent symptoms develop over time. The last decade has witnessed the invention of devices designed to reconstruct the spinal motion segment. These devices can be divided into those that primarily function to replace a nucleus pulposus and those that completely replace the disc complex. In this article the author reviews the background leading to the development of the current group of disc replacements. The design and preliminary clinical results obtained using major lumbar and cervical devices are also reviewed.

Abstract Introduction Isolated acute bilateral foot drop due to degenerative spine disease is an extremely rare neurosurgical presentation, whilst the literature is rich with accounts of chronic bilateral foot drop occurring as a sequela of systemic illnesses. We present, to our knowledge, the largest case series of acute bilateral foot drop, with trauma and relevant systemic illness excluded. Methods Data from three different centres had been collected at the time of historic treatment, and records were subsequently reviewed retrospectively, documenting the clinical presentation, radiological level of compression, timing of surgery, and degree of neurological recovery. Results Seven patients are presented. The mean age at presentation was 52.1 years (range 41–66). All patients but one were male. All had a painful radiculopathic presentation. Relevant discopathy was observed from L2/3 to L5/S1, the commonest level being L3/4. Five were treated within 24 h of presentation, and two within 48 h. Three had concomitant cauda equina syndrome; of these, the first two made a full motor recovery, one by 6 weeks follow-up and the second on the same-day post-op evaluation. Overall, five out of seven cases had full resolution of their ankle dorsiflexion pareses. One patient with 1/5 power has not improved. Another with 1/5 weakness improved to normal on the one side and to 3/5 on the other. Conclusion When bilateral foot drop occurs acutely, we encourage the consideration of degenerative spinal disease. Relevant discopathy was observed from L2/3 to L5/S1; aberrant innervation may be at play. Cauda equina syndrome is not necessarily associated with acute bilateral foot drop. The prognosis seems to be pretty good with respect to recovery of the foot drop, especially if partial at presentation and if treated within 48 h.

State Examination

Cognitive status has been reported to affect the peri-operative and post-operative outcomes of certain surgical procedures. This prospective study investigated the effect of preoperative cognitive impairment on the postoperative course of elderly patients (n = 122, >65 years), following spine surgery for degenerative spinal disease. Data on demographic characteristics, medical history, and blood analysis results were collected. Preoperative cognition was assessed using the mini-mental state examination, and patients were divided into three groups: normal cognition, mild cognitive impairment, and moderate-to-severe cognitive impairment. Discharge destinations (p = 0.014) and postoperative cardiopulmonary complications (p = 0.037) significantly differed based on the cognitive status. Operation time (p = 0.049), white blood cell count (p = 0.022), platelet count (p = 0.013), the mini-mental state examination score (p = 0.033), and the Beck Depression Inventory score (p = 0.041) were significantly associated with the length of hospital stay. Our investigation demonstrated that improved understanding of preoperative cognitive status may be helpful in surgical decision-making and postoperative care of elderly patients with degenerative spinal disease.

Background: Several studies reported improved outcomes with conventional treatments (CT, i.e., chemotherapy ± targeted therapy) administered after immune checkpoints inhibitors (ICI) in certain tumor types. No data are available concerning patients (pts) with metastatic colorectal cancer (mCRC) harboring mismatch repair deficiency/microsatellite instability (dMMR/MSI). We aimed to assess the outcomes of dMMR/MSI mCRC pts receiving CT after ICI failure. Methods: We conducted a retrospective multicenter study investigating the outcomes of all dMMR/MSI mCRC pts who received post-ICI CT between 2015 and 2020. Results: 31 pts (male 61%, median age 56 years) were included. ICI was an anti-PD(L)1 monotherapy in 71% of pts, and 61% received >2 lines before post-ICI CT. The overall response rate and disease control rate were 13% and 45%, with a median progression-free survival (PFS) and overall survival of 2.9 and 7.4 months, respectively. No association of the outcomes with either ICI efficacy or anti-angiogenic agents was observed. Prolonged PFS (range 16.1–21.3 months) was observed in 4 pts (13%). Conclusions: Although conducted on a limited number of patients, our results do not support an association of previous ICI treatment with an enhanced efficacy of CT in dMMR/MSI mCRC. However, prolonged disease control was observed in several cases, suggesting that some pts might derive an unexpected benefit from post-ICI treatments.

ABSTRACT Cervical arterial dissection accounts for only a small proportion of ischemic stroke but arouses scientific interest due to its wide clinical variability. Objective: This study aimed to evaluate its risk factors, outline its clinical characteristics, compare treatment with antiaggregation or anticoagulation, and explore the prognosis of patients with cervical arterial dissection. Methods: An observational, retrospective study using data from medical records on patients with cervical arterial dissection between January 2010 and August 2015. Results: The total number of patients was 41. The patients' ages ranged from 19 to 75 years, with an average of 44.5 years. The most common risk factor was smoking. Antiaggregation was used in the majority of patients (65.5%); 43% of all patients recanalized in six months, more frequently in patients who had received anticoagulation (p = 0.04). Conclusion: The presence of atherosclerotic disease is considered rare in patients with cervical arterial dissection; however, our study found a high frequency of hypertension, smoking and dyslipidemia. The choice of antithrombotic remains controversial and will depend on the judgment of the medical professional; the clinical results with anticoagulation or antiaggregation were similar but there was more recanalization in the group treated with anticoagulation; its course was favorable in both situations. The recurrence of cervical arterial dissection and stroke is considered a rare event and its course is favorable.

Abstract Background: Degenerative spinal disease surgery is frequently performed in most neurosurgical departments. Unplanned 30-day readmissions represent a significant economic burden and have been used in several studies as a tool to evaluate quality of patient care. Objective: To review 30-day unplanned readmission rates after degenerative spinal disease surgery in our department, in order to identify their causes and determine strategies aimed at decreasing their frequency. Methods: A retrospective analysis was performed on all patients operated in our department for spinal stenosis or disc herniation over a 3 year period (January 2014 – December 2016), evaluating the rate and causes of unplanned readmission in the first month after discharge. Complications were divided in medical and surgical. Results: Out of the 1106 patients included, 33 (2,98%) presented a 30-day unplanned readmission. The percentage was higher after disc herniation surgery (3,40%), compared to spinal stenosis (1,92%). Pain management was the most common medical cause for readmission (45,45%), while in the surgical group, CSF leaks were the most frequent complication (18,18%). Conclusions: The rate of 30-day readmissions was low in our series but, even so, they associate significant costs. They could be avoided by applying correct and aseptic surgical technique, proper availability of dural sealing agents and superior patient medical education.

Peritoneal dialysis (PD) in the Pacific is the predominant dialysis modality for home dialysis patients. Patient location, age, personal preference, and medical condition are all taken into consideration. However, with the steadily increasing number of patients on PD, financial constraints are now affecting the nurse-patient ratios. As a consequence, PD nurses are constantly seeking new and improved clinical practice regimes with which they can provide and maintain quality, cost-effective nursing care. To enable PD nurses to provide such care, they are now, more than ever, Involved in patient, professional, and management issues. These patient issues include, but are not limited to: the elderly, the diabetic, the indigenous patient, and their carers, peritonitis, exit-site infection, and adequate dialysis. Professional issues include the development of standards of clinical practice, nursing research, quality improvement, and tertiary education. Management issues are constantly encroaching into the clinical practice setting, therefore the PD nurse must now justify spending, develop strategic plans, and meet annual budgets. In conclusion, it can be seen that PD nurses in the Pacific are faced with similar patient-care, professional, and management issues as their counterparts throughout the world.
