Abstract Background Broadband noise (nonnotched) and notched noise are common sound sources in sound therapy for tinnitus relief. Studies on sound therapy using nonnotched or notched stimuli have reported large and small tinnitus improvements depending on the participant. However, the more effective sound source remains unclear given the among-study methodology differences. Purpose This study aimed to evaluate the tinnitus relief effects of sound therapy using stimuli with different spectral characteristics. Research Design This was a prospective study involving within-subject (baseline vs. 12-month follow-up) measurements for two groups (notched noise group vs. broadband noise group). Study Sample We enrolled 30 adults with subjective and tonal tinnitus (notched noise group: 16, broadband noise group: 14). Intervention The participants underwent 3-hour daily sound therapy using either notched noise or broadband noise for 12 months. The stimulus level for sound therapy was set to each participant's mixing point. Data Collection and Analysis Tinnitus loudness and the Korean version of the Tinnitus Primary Function Questionnaire score were measured at baseline and at the 12-month follow-up time point. Results Both groups showed a significant improvement in tinnitus loudness and the Korean version of the Tinnitus Primary Function Questionnaire score. Conclusions Notched and nonnotched stimuli are equally effective at the mixing point in sound therapy for tinnitus relief. Individuals with difficulties in tinnitus frequency measurement could easily undergo sound therapy using nonnotched stimuli.

Purpose: This study aimed to identify the effects of sound therapy according to various types of stimuli for 3 months in people with chronic tinnitus.Methods: Fifty-eight participants with chronic tinnitus based on inclusive and exclusive criteria were randomly assigned to one of the three groups: broadband noise group, nature sound group, and music sound group. Each group received sound therapy for 3 months and the level of stimulus was set to the level of the mixing point. To measure the change in participants’ tinnitus, the Korean version of the Tinnitus Primary Function Questionnaire (K-TPFQ) was used at the initial and 3-month follow-up sessions.Results: In the mixed model analysis of variance, the main effects of time were significant in almost all the K-TPFQ categories, except for the hearing category. However, the main effect of groups was not significant in most of the K-TPFQ categories, except for the sleep category. The main effects of interaction with group × time were not significant.Conclusion: The results of this study indicate that sound therapy for 3 months could be effective in the management of tinnitus. However, no difference in the effect of sound therapy according to the type of stimuli was noted. These results show that sound therapy could be an effective method for people with tinnitus, regardless of the type of stimulus.

Abstract Funding Acknowledgements Type of funding sources: None. INTRODUCTION Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is an essential tool for the management of refractory cardiogenic shock. Little is known about the incidence of thromboembolic events after V-A ECMO decannulation, although some studies report a high incidence of cannula-related venous thrombosis after venovenous extracorporeal membrane oxygenation (VV-ECMO). Due to this fact, in our institution anticoagulation therapy is systematically prescribed for at least 3 months after VA-ECMO per protocol.  AIM The main objective of this study was to explore the feasibility of 3-month anticoagulation therapy after VA-ECMO decannulation. METHODS We performed a prospective study that included 27 consecutive patients who were successfully treated with VA-ECMO in a medical ICU between 2016 and 2019 and were prescribed 3-month anticoagulation therapy per protocol after decannulation. Exclusion criteria was dying on ECMO or while on the ICU. Data analysis included demographics, mean days on ECMO, 3-month survival, and thromboembolic and bleeding events (excluding immediate post-decannulation bleeding, since anticoagulation was prescribed 24h after). RESULTS Our cohort consisted mainly of men (N = 21, 78%), with a mean age of 60 ± 11 years and a mean time on VA-ECMO of 8 ± 3 days, who primarily suffered from post-cardiotomy cardiogenic shock (N = 9, 34%) or acute myocardial infarction (N = 6, 23%). 5 patients (18%) received a heart transplant. Regarding anticoagulation, 15 patients (60%) had other indications apart from the protocol, like incidental thrombus diagnosis (N = 7, 26%) or valve surgery (N = 5, 18%). Anticoagulation therapy was not feasible in 1 patient (4%) with severe thrombopenia. No patients had severe or life-threatening bleeding events in the follow-up, although 8 patients (30%) had bleeding events, mainly gastrointestinal bleeding (N = 4, 15%), requiring withdrawal of anticoagulation in 1 patient. The incidence of thromboembolic events was 7%; two patients with low-risk pulmonary embolisms. During the 3-month follow-up survival rate was 95%. CONCLUSIONS This is the only study to date addressing the strategy of 3-month anticoagulation therapy after VAECMO, showing it is feasible and safe and may be helpful in reducing or ameliorate thromboembolic complications in the follow-up, although it is not exempt of complications.

Background: Patients who are refractory to initial management of trochlear dysplasia, which consists of bracing and physical therapy, may be candidates for trochleoplasty. Indications: Indications for trochleoplasty include Dejour classification type B or D trochlear dysplasia, supratrochlear spur height ≥7 mm, and a positive J sign on examination. Technique Description: The thick shell sulcus-deepening trochleoplasty technique involves removing the supratrochlear spur by creating a 5-mm–thick osteochondral shell with underlying cavity, dividing the thick shell into medial and lateral leaflets, and securing the leaflets with absorbable sutures. This establishes a new trochlear groove that is flush with the anterior cortex of the femur. Results: A review of 21 studies with length of follow-up from 8.8 months to 15 years found postoperative dislocation was present in 0% to 15% of patients and the patient satisfaction ranged from 81.0% to 94.4%. A prospective study with a minimum 2-year follow-up found no cases of recurrent dislocation, no progression of radiographic arthritis, 84.8% of patients returned to sport, and the patient satisfaction was a 9.1/10. Discussion/Conclusion: Sulcus-deepening trochleoplasty for trochlear dysplasia provides patellar stability and excellent patient satisfaction.

AbstractObjectivesTo evaluate the impact of placental anastomoses on the intrauterine growth of monochorionic (MC) twins.MethodsA prospective study was conducted in a group of 53 MC twins. Intrapartally umbilical cords were clamped to identify placental sides corresponding to each twin. The postnatal dye injection technique was administered to evaluate vascular anastomoses, their number and type and visualize placental territory sharing patterns. Data from digital analysis were correlated with obstetrical follow-up.ResultsVascular anastomoses were revealed in 88.7% of cases. Arteriovenous (AV) anastomoses occurred in 75.4% and arterioarterial (AA) in 71.1% while venovenous (VV) in 26.4%. In the subgroup of MC twins without placental anastomoses, significantly higher birthweight difference and discordance were revealed when compared to MC twins without anastomoses (382.0 vs. 22 g; P = 0.03 and 49.14% vs. 16.02%; P = 0.03). On the other hand, in subgroups of MC twins with at least one AA anastomosis, twins’ birthweights were similar (p = ns) despite significantly higher placental territory sharing discordance (30.44% vs. 15.81%; P = 0.31).ConclusionsVascular anastomoses have a major impact on the intrauterine growth of MC twins. In certain cases, they may cause specific complications; however, in general, they regulate intertwin blood exchange and may compensate unequal placental territory.

Abstract Objective The aim of this article was to analyze the clinical and radiological outcomes of transpedicular decompression (posterior approach) and anterolateral approach in patients with traumatic thoracolumbar spinal injuries. Methods  It was a prospective study of patients with fractures of dorsolumbar spine from December 2011 to December 2013. A total of 60 patients with traumatic spinal injuries were admitted during the study period (December 2011–2013), of which 51 cases were finally selected and taken for operations while 3 were eventually lost in follow-up. Twenty patients were operated by anterolateral approach, titanium mesh cage, and fixation with bicortical screws. Twenty-eight patients were treated with posterior approach and transpedicular screw fixation. Clinical and radiographic evaluations were performed on all 48 patients before and after surgery. Results There were 48 patients of thoracolumbar burst fractures with 40 male and 8 female patients. Range of follow-up was from 1 month to 20 months, with a mean of 7.4. Preoperatively in anterior group, 65% of the patients were bed ridden, 20% patients were able to walk with support, and 15% of the patients were able to walk without support. In posterior group, 78.57% patients were bed ridden, 10.71% were able to walk with support, and 10.71% patients were able to walk without support. Kyphotic angle changes were seen in 16 patients out of 18 in anterior group and 20 patients in posterior group out of 25. Out of 18 patients in anterior group, 14 showed reduction in kyphotic angle of 10 to 100 (improvement), with mean improvement of 4.070. In posterior group, 7 patients showed improvement of 10 to 80 (reduction in kyphotic angle) whereas 13 patients showed deterioration of 1 to 120. The mean improvement was 2.140 in 7 patients and mean deterioration was 4.920. No statistical difference was found (p > 0.05) regarding improvement in urinary incontinence during the follow-up period. Conclusion There are significant differences in anterior and posterior approaches in terms of clinical improvement. Compared with posterior approach, the anterolateral approach can reduce fusion segment and well maintain the kyphosis correction. The selection of treatment should be based on clinical and radiological findings, including neurological deficit.
