A systematic review of full endoscopic versus micro-endoscopic or open discectomy for lumbar disc herniation.

Aim: Endoscopic discectomies provide several advantages over other techniques such as traditional open lumbar discectomy (OLD) including possibly decreased complications, shorter hospital stay and an earlier return to work. Methods: An electronic database search including MEDLINE/PubMed, EMBASE, Scopus, Cochrane Database of Systematic Reviews and Cochrane Controlled trials (CENTRAL) were reviewed for randomized controlled trials (RCTs) only. Results: A total of nine RCTs met inclusion criteria. Three showed benefit of endoscopic discectomy over the comparator with regards to pain relief, with the remaining six studies showing no difference in pain relief or function. Conclusion: Based on review of the nine included studies, we can conclude that endoscopic discectomy is as effective as other surgical techniques, and has additional benefits of lower complication rate and superior perioperative parameters.

Lay abstract This systematic review investigates the use of a common surgical procedure, endoscopic discectomy, for the surgical treatment of lumbar disc herniation. It is a type of minimally invasive spine surgery (MISS) procedure, which has been shown to be not only effective in outcomes, but also optimal for peri-operative parameters, such as post-operative hospital stay, time duration of surgery and blood loss during the procedure. We utilized five search databases to collect data on only randomized controlled studies that investigated endoscopic discectomy compared with another surgical technique. Our results include nine randomized controlled trials, three of which showed improvement in pain scores for endoscopic discectomies. Consequently, in combination with the optimal peri-operative measures, it is concluded that endoscopic discectomy is a reasonable procedure to treat lumbar disc herniation surgically.

Treatment of knee osteoarthritic pain with platelet-rich plasma: a systematic review of clinical studies.

Introduction: Knee osteoarthritis is a degenerative joint disease that is secondary to degradation of articular cartilage, reformation of subchondral bone through degradation and proliferation as well as presence of synovitis. Materials & methods: This systematic review was conducted and reported as per Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Results: A total of 30 of the 48 comparators showed statistically significant superiority with platelet-rich plasma (PRP) compared with a control, while the other 16 comparators showed no significant difference between PRP and the comparator. Conclusion: We can only recommend PRP for patients with early-stage osteoarthritis (I or II) and who are aged below 65, based on our findings. Based on the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) recommendations, while studies reviewed were randomized controlled studies, and therefore, high grade, due to variance in imprecision, risk of bias and inconsistency among the 37 studies, it would be reasonable to rate this paper as subjectively moderate.

The Regenerative Potential of Therapeutic Ultrasound on Neural Tissue: A Pragmatic Review.

OBJECTIVES: Low-intensity ultrasound (LIU)/low-intensity pulsed ultrasound (LIPUS) may influence nerve tissue regeneration and axonal changes in the context of carpal tunnel syndrome (CTS) and in the animal model. The purpose of this pragmatic review is to understand the current knowledge for the effects of low-intensity therapeutic ultrasound in the animal and human model and determine the future directions of this novel field. DESIGN: Pragmatic review. METHODS: We performed a literature search of available material using OVID, EmBase, and PubMed for LIU/LIPUS, all of which were preclinical trials, case reports, and case series using animal models. For CTS, a literature search was performed on PubMed (1954 to 2019), CENTRAL (the Cochrane Library, 1970 to 2018), Web of Science (1954 to 2019), and SCOPUS (1954 to 2019) to retrieve randomized controlled trials. RESULTS: Eight articles were discussed showing the potential effects of LIU on nerve regeneration in the animal model. Each of these trials demonstrated evidence of nerve regeneration in the animal model using LIPUS or LIU. Seven randomized controlled trials were reviewed for ultrasound effects for the treatment of carpal tunnel syndrome, each showing clinical efficacy comparable to other treatment modalities. CONCLUSIONS: LIU/LIPUS is a promising and noninvasive means of facilitating nerve regeneration in the animal model and in the treatment of carpal tunnel syndrome. Although many of the trials included in this review are preclinical, each demonstrates promising outcomes that could eventually be extrapolated into human studies.

Therapeutic Ultrasound for Pain Management in Chronic Low Back Pain and Chronic Neck Pain: A Systematic Review.

BACKGROUND: Low back pain (LBP) and neck pain are major causes of pain and disability that are experienced across all ages. The primary goals of treatment are to improve patient function and facilitate a return to the patient's desired level of daily activity. Therapeutic ultrasound is a noninvasive modality widely utilized in the management of musculoskeletal disorders, but there continues to be controversy regarding its use due to insufficient evidence of effectiveness. The objective of this systematic review was to evaluate the effectiveness of therapeutic ultrasound in the management of patients with chronic LBP and neck pain. METHODS: Using PRISMA guidelines, a search of the PubMed and CENTRAL (The Cochrane Library) databases was performed to retrieve randomized controlled trials (RCTs) that evaluated therapeutic ultrasound in patients with chronic LBP or neck pain. RESULTS: The search strategy identified 10 trials that met the criteria for inclusion. Three studies in LBP reported that both therapeutic and sham (placebo) ultrasound provided significant improvement in pain intensity. In each of these studies, ultrasound was found to be more effective than placebo when using only one of several validated instruments to measure pain. Three of the four studies on neck pain demonstrated significant pain relief with ultrasound in combination with other treatment modalities. However, only one of these studies demonstrated that the use of ultrasound was the cause of the statistically significant improvement in pain intensity. CONCLUSIONS: Therapeutic ultrasound is frequently used in the treatment of LBP and neck pain and is often combined with other physiotherapeutic modalities. However, given the paucity of trials and conflicting results, we cannot recommend the use of monotherapeutic ultrasound for chronic LBP or neck pain. It does seem that ultrasound may be considered as part of a physical modality treatment plan that may be potentially helpful for short-term pain relief; however, it is undetermined which modality may be superior. In both pain syndromes, further trials are needed to define the true effect of low-intensity ultrasound therapy for axial back pain. No conclusive recommendations may be made for optimal settings or session duration.

Therapeutic Ultrasound for Chronic Pain Management in Joints: A Systematic Review.

BACKGROUND: Treatments for joint pain and dysfunction focus on restoration of joint motion, improvement in pain and a return to the previous level of the patient's daily activity. Therapeutic ultrasound is a noninvasive modality widely utilized in the management of musculoskeletal disorders. The objective of this systematic review was to evaluate the effectiveness of therapeutic ultrasound in the management of patients with knee, shoulder and hip pain. METHODS: Using PRISMA guidelines, a search of the PubMed, CENTRAL (The Cochrane Library), Web of Science and Scopus databases was performed to retrieve randomized controlled trials (RCTs) that evaluated therapeutic ultrasound (continuous and pulsed) in patients with chronic knee, shoulder and hip pain. RESULTS: The search strategy identified 8 trials for knee, 7 trials for shoulder and 0 trials for hip that met the criteria for inclusion. All 8 trials showed improvement in knee pain, and of these studies 3 showed statistical significance improvement for therapeutic ultrasound versus the comparator. For shoulder pain, all 7 trials showed reduction in pain, but should be noted that 4 of studies demonstrated that therapeutic ultrasound is inferior to the comparator modality. CONCLUSION: Therapeutic ultrasound is frequently used in the treatment of knee, shoulder and hip pain and is often combined with other physiotherapeutic modalities. The literature on knee arthritis is most robust, with some evidence supporting therapeutic ultrasound, though the delivery method of ultrasound (pulsed vs continuous) is controversial. As a monotherapy, ultrasound treatment may not have a significant impact on functional improvement but can be a reasonable adjunct to consider with other common modalities. In all three pain syndromes, especially for hip pain, further trials are needed to define the true effect of low-intensity ultrasound therapy knee, shoulder and hip pain. No conclusive recommendations may be made for optimal settings or session duration.

Pre-existing opioid use disorder and postoperative outcomes after appendectomy or cholecystectomy: A multi-state analysis, 2007-2014.

INTRODUCTION AND OBJECTIVES: Opioid use disorder has become increasingly prevalent in recent years. Previous studies have shown that patients with opioid use disorder undergoing orthopedic, elective abdominopelvic, and cardiac procedures have poorer postoperative outcomes. The aim of this study was to examine the effect of pre-existing opioid use disorder on postoperative outcomes including in-hospital mortality, hospital length of stay (LOS), hospital readmission, and postoperative complications in patients undergoing appendectomy or cholecystectomy. METHODS: The authors used administrative data from the State Inpatient Databases of the Healthcare Cost and Utilization Project for the years 2007-2014 from California, Florida, Kentucky, Maryland, and New York. The authors compared unadjusted rates of in-hospital mortality, postoperative complications, LOS, and 30-day and 90-day readmission status. The authors calculated the adjusted odds ratio (OR) for their outcomes using logistic regression models. RESULTS: In all, 488,981 appendectomy patients and 790,491 cholecystectomy patients aged ≥ 18 years were included in the analysis. Appendectomy (OR 2.26) but not cholecystectomy patients with opioid use disorder had statistically significant adjusted odds of in-hospital death. Patients with opioid use disorder (overall reported, and by each procedure separately) had higher adjusted odds of postoperative complication (OR 1.46), 30-day readmission (OR 1.80), 90-day readmission (OR 1.98), and longer LOS (OR 1.37). CONCLUSIONS: The authors found higher unadjusted rates and adjusted ORs of in-patient mortality, hospital readmission, and postoperative complications in patients with opioid use disorder undergoing common abdominal surgeries. The authors' study shows that opioid use disorder is a risk factor for poorer postoperative outcomes in this surgical patient population.

Sickle cell disease and readmissions rates after lower extremity arthroplasty: a multistate analysis 2007-2014.

AIM: To compare readmission rates between patients with sickle cell disease (SCD) and non-sickle cell disease undergoing total hip and knee arthroplasty (THA and TKA). METHODS: Identified adult patients who underwent THA or TKA from 2007 to 2014 in California, Florida, New York, Maryland and Kentucky using a multistate database. Outcomes were 30- and 90-day readmission rates, mortality, complications, length of stay and hospital charges. Logistic regression models were used for analysis. RESULTS: Compared with non-sickle cell disease patients following TKA and THA, SCD patients had higher odds of 30- (odds ratio [OR]: 3.79) and 90-day readmissions (OR: 4.15), mortality (OR: 6.54), more complications, longer length of stay, and higher total charges. CONCLUSION: Following TKA and THA, SCD is associated with higher readmissions and worse outcomes.

Nonopioid versus opioid agents for chronic neuropathic pain, rheumatoid arthritis pain, cancer pain and low back pain.

Chronic pain continues to be a major health issue throughout the world and a huge economic burden for nations around the world. While the use of opioids does have risks, they are still widely used by clinicians as a treatment option for various chronic pain conditions. This review explores and compares the efficacy and safety of opioid and nonopioid agents for the following commonly encountered chronic pain conditions: neuropathic pain, rheumatoid arthritis joint pain, cancer pain and low back pain. Our findings demonstrate that while there are several nonopioid pharmacologic options that are clinically effective, opioids maintain a role in the treatment of certain chronic pain conditions and should continue to have an important place in the armamentarium of clinicians.

Spinal epidural abscess associated with an epidural catheter in a woman with complex regional pain syndrome and selective IgG3 deficiency: A case report.

RATIONALE: Continuous epidural infusion of local anesthetic may be an alternative to sympathetic blocks in refractory cases of complex regional pain syndrome (CRPS). Spinal epidural abscess (SEA) is a well-known complication associated with this technique, especially in patients with immune deficiencies. We herewith report a cervical SEA associated with an epidural catheter in a woman with CRPS and selective IgG3 subclass deficiency. PATIENT CONCERNS: Severe pain interfering with activities of daily living. DIAGNOSIS: Complex regional pain syndrome type-1 with involvement of upper extremity. INTERVENTIONS: The patient underwent inpatient epidural infusion for management of left upper extremity CRPS. Her history was notable for previous left shoulder injury requiring numerous surgical revisions complicated by recurrent shoulder infections, and selective IgG3 deficiency. She received antibiotic prophylaxis and underwent placement of a C6-C7 epidural catheter. On day 5, she became febrile. Neurological examination remained unchanged and an MRI demonstrated acute fluid collection from C3-T1. The following day she developed left arm weakness and was taken for emergent cervical decompression. Intraoperative abscess cultures were positive for Pseudomonas aeruginosa. OUTCOMES: Postoperatively, the patient's neurological symptoms and signs improved. LESSONS: Patients with selective IgG3 deficiency who are being considered for epidural catheterization may benefit from expert consultation with infectious diseases specialist. A history of recurrent device- or tissue-related infections should alert the clinician to the possible presence of a biofilm or dormant bacterial colonization. Close monitoring in an ICU setting during therapy is recommended. In case of early signs of infection, clinicians should have a high suspicion to rule out a SEA in immunocompromised patients.

Utility of smartphone camera in patient management in urology.

INTRODUCTION: To describe the utility of the smartphone camera in patient management in urology. MATERIALS AND METHODS: Clinical scenarios were collected retrospectively in which photographs that were taken on smartphone and transmitted by multimedia messaging service (MMS) served an important role in making a diagnosis and/or helped in the self-monitoring of urologic issues by patients. RESULTS: Scenario 1 - a 39-year-old male that presented to the emergency room (ER) with scrotal pain, bruising, and swelling 1 day after bilateral vasectomy. The on call urologist requested that the ER physician send a photograph of the wound using his smartphone. After examining the photograph, the urologist concluded that the hematoma could be managed conservatively. Scenario 2 - a 40-year-old female who underwent transurethral resection of bladder tumor a month ago and had recurrence of gross hematuria. The surgeon asked the patient to monitor her urine color and to use her smartphone to periodically send a photograph of her urine until it turned clear. CONCLUSIONS: At our institution urology consults have been requested for postoperative patients owning to unfamiliarity with postoperative urology examination. By communicating with the on call urologist through MMS images of incisions or urine color, management of these patients has become more timely and efficient. Smartphone camera use can also decrease the in house time spent by on call residents, thus aiding in conforming to duty hours restrictions. Furthermore, this technology has potential for helping patients monitor their disease course, thus reducing hospital visits, anxiety, and healthcare costs.
