STUDY DESIGN: Prospective cohort study. PURPOSE: To assess whether additional implantation of Coflex following spinal decompression provided better clinical outcomes compared to decompression alone for symptomatic lumbar spinal stenosis (LSS) and to determine whether improvement in clinical outcomes correlated with changes in the radiological indices studied. OVERVIEW OF LITERATURE: Literature on benefits of additional Coflex implantation compared to decompression alone for symptomatic LSS is limited. METHODS: Patients with symptomatic LSS who met the study criteria were offered spinal decompression with Coflex implantation. Those patients who accepted Coflex implantation were placed in the Coflex group (n=22); while those opting for decompression alone, were placed in the comparison group (n=24). Clinical outcomes were assessed preoperatively, six-months, one-year and two-years postoperatively, using the Oswestry disability index, 100 mm visual analogue scale (VAS)-back pain and VAS-leg pain, and short form-36 (SF-36). Radiological indices (disc height, foraminal height and sagittal angle) were assessed preoperatively, six months, one year, and two years postoperatively. RESULTS: Both groups showed statistically significant (p<0.001) improvement in all the clinical outcome indicators at all points in time as compared to the preoperative status. However, improvement in the Coflex group was significantly greater (p<0.001) than the comparison group. Changes in the radiological indices did not correlate significantly with the improvement in clinical outcome indicators. CONCLUSIONS: Additional Coflex implantation after spinal decompression in symptomatic LSS offers better clinical outcomes than decompression alone in the short-term. Changes in radiological indices do not correlate with the improvements in clinical outcomes after surgery for symptomatic LSS.

STUDY DESIGN: A prospective observational study. PURPOSE: To evaluate the role of nucleoplasty in the management of discogenic axial back pain; to determine the influence of concordant pain during provocative discography, annular tear and loss of disc height on the outcome of nucleoplasty. OVERVIEW OF LITERATURE: The role of nucleoplasty in the management of radicular leg pain due to disc herniation is known. However, the data regarding its role in the management of discogenic axial back pain is scarce. METHODS: A prospective evaluation of 30 patients with discogenic axial back pain undergoing nucleoplasty was performed. Pain, functional disability and quality of life were assessed using the 100 mm visual analogue scale (VAS), Oswestry Disability Index (ODI) and Short Form-36 (SF-36), respectively. RESULTS: The mean reduction in VAS was 31.03 and 29.03; mean reduction in ODI was 24.53 and 20.60; and mean increment in SF-36 was 13.58 and 12.30, at 6 months and at 12 months, respectively. The differences were statistically significant (p <0.05). Concordant pain during provocative discography, annular tear and loss of disc height did not affect a clinically significant improvement in any of the three outcomes (p =0.882, 0.213, and 0.170; respectively). CONCLUSIONS: Nucleoplasty produced statistically significant improvements in pain, functional disability and quality of life in patients with discogenic low back pain at 6 months and at 12 months. Concordant pain during provocative discography, annular tear and loss of disc height did not influence any of the outcomes after nucleoplasty in patients with discogenic axial back pain.

Purpose:
To evaluate the clinical presentation, management, and outcome of eyes with an inadvertent globe perforation during peribulbar or retrobulbar block.
Methods:
This retrospective study evaluated the eyes which had an accidental globe perforation during local ocular anesthesia from 2012 to 2020. The patients were divided into three groups: group 1, Clear media with no rhegmatogenous retinal detachment (RRD); group 2, significant vitreous hemorrhage (VH) precluding the retinal view without RRD; and group 3, RRD with/without VH.
Results:
Twenty-five patients were included in the study. The mean axial length (AL) was 24.7 ± 2.7 mm (range, 20.9–31.2 mm). The most common presenting feature was VH (n = 14). The treatment included retinal laser barrage (n = 7) and vitrectomy (n = 17). Retinal breaks were identified in all the eyes (total breaks = 37). The mean presenting best-corrected visual acuity in groups 1, 2, and 3 were logarithm of the minimum angle of resolution 0.79 ± 0.73, 1.82 ± 0.78, and 2.13 ± 0.59 respectively. All the treated patients had an attached retina at the last follow-up. The mean final best-corrected visual acuity for each group was logarithm of the minimum angle of resolution 0.59 ± 0.79, 0.48 ± 0.26, and 1.25 ± 0.64, respectively (p = 0.006). The development of RRD was associated with a larger AL (p = 0.015); while the development of significant VH associated with the superior location of the perforation (p = 0.015), late recognition of the perforation (p = 0.004), and multiple perforations (p = 0.015).
Conclusions
Early recognition and intervention in eyes with an inadvertent perforation can lead to a good outcome. Eyes with a longer AL, superior, and multiple perforations are at higher risk of developing complications like RRD and VH. Complications like RRD, macular injury, and vascular occlusion are risk factors for poor prognosis.

Background and Objectives:
This study investigates the role of manuka honey in the healing of postoperative mastoid cavity.Subjects and Method This was a single centre prospective study on 40 consecutive patients of chronic otitis media undergoing canal wall down mastoidectomy. Manuka honey soaked in gel foam was kept in the mastoid cavity for the study group and antibiotic soaked gel foam was kept for the control group. Culture swabs from mastoid granulations were sent at various times from both groups. The healing of the mastoid cavity was assessed in the follow up period.
Results:
Preoperatively 15 out of 20 patients (75%) had a positive aural swab culture in the study group while 11 out of 20 (55%) in the control group had a positive aural swab culture. The most common organism isolated was Pseudomonas aeruginosa and Proteus mirabilis. One month after mastoidectomy only 4 patients (20%) had sterile culture and 16 patients (80%) had grown organisms; in the control group, 7 patients (35%) had sterile culture and 13 patients (65%) had growth on culture. The mean merchant scores for the study group and the control were 2.61 (2-5) and 2.05 (1-4), respectively. At 3 months 13 patients (65%) with sterile culture and 7 patients (35%) had growth on culture; in the control group, 16 patients (80%) had sterile culture and 4 had shown persistent growth on culture (p=0.28). All positive cultures were aerobic in both groups. The mean merchant scores for the study group and the control were 1.03 (0-4) and 0.7 (0-3), respectively (p=0.09).
Conclusion
Healing of mastoid cavity was almost similar in both groups (p>0.05). Manuka honey exhibited antibacterial activity against Pseudomonas, Proteus, Klebsiella, Escherichia coli, Staphylococcus.

The coronavirus disease 2019 (COVID-19) pandemic has caused pronounced strain on global healthcare systems, forcing the streamlining of clinical activities and conservation of health resources. There is a pressing need for institutions to present discipline-specific strategies for the management of COVID-19 patients. We present the comprehensive considerations at the National University Hospital, Singapore from the surgeon’s and anesthetist’s perspectives in the performance of spinal surgery in COVID-19 patients. These are based on national guidelines and overarching principles of protection for the healthcare workers (HCWs) and efficiency in surgical planning. The workflow begins with the emergency department screening that has been adapted to the local epidemiology of COVID-19 in order to identify suspected/confirmed cases. If patient history cannot be obtained, demographic, clinical, and imaging data are used. Designated orthopedic “contaminated teams” are available 24/7 with an activation time of <30 minutes for review. In cases where sub-specialty spine surgeons were required, these professionals were inducted into the “contaminated team” and quarantined until cleared to return to work. Indications for emergency spine surgery were determined pre-emptively. Preoperative surgical considerations included the minimization of manpower, limited dissection, reduced operative time, and judicious use of equipment, leading to reduced aerosolization. Anesthesia considerations include preoperative screening for COVID-19–related concerns that influence surgery, operating room process planning and induction, intraoperative, reversal, recovery, and resuscitation considerations. Focused multi-disciplinary preoperative briefing facilitates familiarization. Surgical, anesthetic, and postoperative workflows were designed to reduce the risk of transmission and protect HCWs while effectively performing spinal surgery. The COVID-19 pandemic has necessitated paradigm shifts in healthcare planning, hospital workflows, and operative protocols. The viral burden does not discriminate between surgeons and physicians, and it is crucial that we, as medical professionals, adapt practices to be malleable and fluid to address the ever-changing developments.

INTRODUCTIONNasopharnygeal carcinoma (NPC) is characterised by early metastases with the skeleton being the most common site of metastases. The ability to prognosticate survival is crucial in the decision whether or not to offer surgery to these patients and the choice of surgery offered. We aimed to evaluate the scoring systems namely: Bauer, Katagiri and Scandinavian Sarcoma Group (SSG) in NPC patients with skeletal metastases.
MATERIALS AND METHODSA total of 92 patients with skeletal metastases from NPC were studied. We retrospectively analysed the actual survival of these patients and compared with predicted survival according to the 3 scoring systems. The predicted survival according to each system was calculated and labelled as A scores. These were then re-scored by assigning NPC as a better prognostic tumour and labelled as B scores. The predicted survival of scores A and B were compared to actual survival. Univariate and multivariate Cox regression analyses were performed. The predictive values of each scoring were calculated.
RESULTSThe median overall survival for the whole cohort was 13 months (range: 1 to 120 months). In multivariate analysis, general condition and visceral metastases showed significant effect on survival. There were statistically significant differences (P <0.001) between the subgroups of the SSG B as well as Katagiri B scoring systems where NPC was classified as a better prognostic tumour. SSG B provided the highest predictive value (0.67) as compared to the other 2 scoring systems.
CONCLUSIONThe SSG and Katagiri score could be used to prognosticate NPC with a statistically significant association with actual survival.

Severe alcoholic hepatitis has very high short term mortality and corticosteroids have been the mainstay of treatment for decades. Patients with Lille score >0.45 are considered non-responders to steroids and have poor outcome. Recently Orthotopic Liver Transplantation (OLT) is being increasingly used as rescue treatment for these patients, without waiting for 6 months of abstinence. Liver transplant is the only rescue treatment which can potentially provide long term benefit for patients who are steroid non-responders. However, with scarcity of organs being a concern, all patients of severe alcoholic hepatitis cannot be chosen for transplantation in an arbitrary way. There is a need for development of predictive tools and objective protocols to select patients who can justify the use of precious liver grafts. With a stringent criteria for selection of patients receiving the graft, liver transplantation in severe alcoholic hepatitis can become a viable rescue therapeutic option conferring significant survival advantage of both short- and long-term basis. The optimal criteria for selection will also prevent misuse of the liver donor pool as well as to prevent mortality in salvageable patients. Further research needs to be done to identify subset of patients which are at low risk of recidivism and also cannot be managed with pharmacotherapy alone. We reviewed the current knowledge on role of OLT in patient with acute severe alcoholic hepatitis in the present review.

Journal of Dental Anesthesia and Pain Medicine 2020;20(4):223-231
Background:
The most frequent complication of nasotracheal intubation (NTI) is epistaxis. Epinephrine nasal gauze packing has been used conventionally as a pre-treatment for reducing epistaxis, but it carries a disadvantage of pain and anxiety in patients. However, xylometazoline drops are easier to administer and more convenient for patients. We aimed at comparing the effectiveness of xylometazoline drops and epinephrine merocele packing in reducing bleeding and postoperative complications in our population.
Methods:
Our study enrolled 120 patients in a double-blind randomized controlled trial. We randomly allocated ASA1 or 2 adult patients into 2 groups: Group X and Group E. Group X received 0.1% xylometazoline nasal drops, and epinephrine (1:10,000) merocele nasal packing was used in Group E. The primary outcome was the incidence of bleeding during NTI; the severity of bleeding, navigability, bleeding during extubation, and postoperative complications were secondary outcomes. We used IBM SPSS and Minitab software for statistical analysis, and P < 0.05 was considered statistically significant.
Results:
We analyzed the data of 110 patients: 55 in Group X and 55 in Group E. The two groups did not have different bleeding incidence (56.4% vs 60.0%; P = 0.70); however, the incidence of severe bleeding was less with xylometazoline than with epinephrine (3.63% vs 14.54%; P < 0.05). We also observed less bleeding during extubation (38.2% vs 68.5%; P < 0.05) with xylometazoline. Other secondary outcomes were akin to both groups.
Conclusion
The incidence of severe and post-extubation bleeding was significantly less with xylometazoline.Hence, it may be an effective alternative for reducing the incidence and severity of epistaxis during NTI.
