Posterior pedicle screw fixation combined with local steroid injections for treating axial eosinophilic granulomas and atlantoaxial dislocation:A case report

BACKGROUND Eosinophilic granuloma(EG)is a proliferative condition that affects the cells of bone tissue.There are no specific clinical signs or imaging manifestations in the early stages of the disease,making it simple to overlook and misdiagnose.Because of the disease's rarity,there is presently no standardized treatment principle.There are few accounts of such occurrences affecting the axis among children.We discovered a case of a child whose EG resulted in atlantoaxial joint dislocation and destruction of the axial bone.CASE SUMMARY After having pharyngeal discomfort for more than six months without a clear explanation,a 6-year-old boy was brought to our hospital.Following a careful evaluation,the pathology indicated a strong likelihood of an axial EG.Ultimately,we decided to treat the boy with posterior pedicle screw fixation and local steroid injections.CONCLUSION EGs of the upper cervical spine are quite uncommon in children,and they are exceedingly easy to overlook or misdiagnose.Posterior pedicle screw fixation and local steroid injections are effective treatments for patients with axial EGs affecting the atlantoaxial junction.

Effects of the Treatment of Carpal Tunnel Syndrome with Surgery and Injections on the Hospital Anxiety and Depression Scale (HADS)

Background: The prevalence of carpal tunnel syndrome (CTS) and of anxiety and depression in primary care practice are high. Different studies had shown an increased prevalence of anxiety and depression in CTS patients. Nevertheless, few papers had been published studying the anxiety and depression scales in the treatment of CTS, either with corticosteroid injections (I) or with surgical decompression (S). Objective: To assess whether clinical improvement observed after the treatment of CTS either with I or with S correlates with an improvement in the punctuations of the Hospital Anxiety and Depression scales (HADS), at 3, 6 and 12-month follow-up. Methods: Randomized and open-label clinical trial, comparing I and S. Patients with symptoms suggestive of CTS (nocturnal paraesthesias) of at least 3 months duration and neurophysiological confirmation were included. Patients with clinically apparent motor impairment were excluded. The subjective evaluation of symptoms was carried out using the visual-analogue scale of pain (VAS-p). Clinical reviews were performed 3, 6 and 12 months after treatment. Each patient completed the HADS questionnaire and a VAS-p at 0, 3, 6, and 12 months. Statistical significance was established using the Student’s t test and the Mann-Whitney U test when necessary. A linear regression analysis was used to know the effect of the treatment adjusted for the initial score of both scales. Results: 65 patients were included (30 in group I and 35 in group S). There was no statistical difference between both groups in terms of age, gender distribution, disease duration, VAS-p, neurophysiological testing severity of CTS or the 8 subscales of HADS. Both groups improved significantly in relation to the baseline VAS-p values, in the reviews at 3, 6 and 12 months, with no significant differences between I and S. At 6 months, the reduction in the anxiety scale was around 3 points for both treatments (S = 3.6 and I = 3.2), without reaching significant differences. At 12 months, it was somewhat higher for those treated with I, but always around 3 points and without significant differences. The Depression scale score was slightly reduced at 6 months, and in a similar way for both groups (I = 1 and S = 1.19;p = 0.8). After 12 months, group I doubled the previous reduction, with group S experiencing a very slight change (I = 1.96 and S = 1.03;p = 0.3). When analysing the effect of group S on group I, the result was a reduction of 0.25 points for Anxiety (p = 0.7) and of 0.02 points for Depression (p = 0.9). Conclusions: Treatment of CTS with I or S results in a similar and discrete improvement in Anxiety scores on the HADS scale at 6 and 12 months. For both types of treatment, the Depression scores barely changed at 6 months, being somewhat higher in group I after 12-month follow-up. The independent effect of the S on both scales is small and not significant.

Endoscopic ultrasound-guided injectable therapy for pancreatic cancer:A systematic review

BACKGROUND Given the low survival rate in pancreatic cancer,new therapeutic techniques have been explored,especially for unresectable or borderline resectable disease.Endoscopic ultrasound(EUS)provides real-time imaging and minimally invasive access for local and targeted injection of anti-tumor agents directly into the pancreatic tumor.Limited studies have been reported using this technique for the treatment of pancreatic ductal adenocarcinoma(PDAC).AIM To evaluate the progress made with EUS-guided injectable therapies in the treatment of PDAC.METHODS All original articles published in English until July 15,2021,were retrieved via a library-assisted literature search from Ovid Evidence-Based Medicine Reviews and Scopus databases.Reference lists were reviewed to identify additional relevant articles.Prospective clinical studies evaluating the use of EUS-guided injectable therapies in PDAC were included.Studies primarily directed at non-EUS injectable therapies and other malignancies were excluded.Retrieved manuscripts were reviewed descriptively with on critical appraisal of published studies based on their methods and outcome measures such as safety,feasibility,and effectiveness in terms of tumor response and survival.Heterogeneity in data outcomes and therapeutic techniques limited the ability to perform comparative statistical analysis.RESULTS A total of thirteen articles(503 patients)were found eligible for inclusion.The EUS-injectable therapies used were heterogeneous among the studies consisting of immunotherapy(n=5)in 59 patients,chemotherapy(n=1)in 36 patients,and viral and other biological therapies(n=7)in 408 patients.Eleven of the studies reviewed were single armed while two were double armed with one randomized trial and one non-randomized comparative study.Overall,the included studies demonstrated EUS-guided injectable therapies to be safe and feasible with different agents as monotherapy or in conjunction with other modalities.Promising results were also observed regarding their efficacy and survival parameters in patients with PDAC.CONCLUSION EUS-guided injectable therapies,including immunotherapy,chemotherapy,and viral or other biological therapies have shown minimal adverse events and potential efficacy in the treatment of PDAC.Comparative studies,including controlled trials,are required to confirm these results in order to offer novel EUS-based treatment options for patients with PDAC.
