ABSTRACT

Soccer is the most popular sport in the world, with over 265 million active players and approximately 0.05% professional players worldwide. The Fédération Internationale de Football Association (FIFA) has made preparticipation screening recommendations which involve electrocardiography and echocardiography being performed prior to international competition. The aim of preparticipation cardiovascular screening in young athletes is to detect asymptomatic individuals with cardiovascular disease at risk of sudden cardiac death (SCD). The incidence of SCD in young athletes (age≤ 35 years) is 0.6-3.6 in 100,000 persons/year, with most deaths due to cardiovascular causes. Arrhythmogenic right ventricular cardiomyopathy (ARVC) is one of the leading causes of SCD in young athletes. It is a genetic disease characterized by progressive fibrofatty replacement of the myocardium with variable phenotypic expression. Exercise-induced cardiac remodeling in conjunction with extensive T-wave inversion raises concern for ARVC. This case report and literature review explores a potential mimic for ARVC, the role of cardiovascular screening in sport, and the use of a multimodality approach for risk stratification and management.

ABSTRACT

PNAzymes are a group of artificial enzymes which show promising results in selective and efficient cleavage of RNA targets. In the present study, we introduce a series of metal chelating groups based on N,N-bis(2-picolyl) groups (parent, 6-methyl and 6-amino substituted) as the active sites of novel PNAzymes. An improved synthetic route for the 6-amino analogues is described. The catalytic activity of the chelating groups for cleaving phosphodiesters were assessed with the model substrate 2-hydroxypropyl p-nitrophenyl phosphate (HPNPP), confirming that the zinc complexes have the reactivity order of parent < 2-methyl < 2-amino. The three ligands were conjugated to a PNA oligomer to form three PNAzymes which showed the same order of reactivity and some sensitivity to the size of the RNA bulge designed into the catalyst-substrate complex. This work demonstrates that the kinetic activity observed for the model substrate HPNPP could be translated onto the PNAzymes, but that more reactive Zn complexes are required for such PNAzymes to be viable therapeutic agents.

ABSTRACT

Background: Post-traumatic acute brain swelling (ABS) is a major cause of elevated intracranial pressure and thus mortality. The current definition of post-traumatic ABS has certain limitations, and there is limited information available regarding ABS associated with traumatic acute subdural hematoma (ASDH). Objectives: To investigate the incidence, risk factors, and clinical outcomes of ABS associated with traumatic ASDH. Design: Retrospective study. Methods: Data for 161 patients diagnosed with traumatic ASDH were retrospectively collected. Novel computed tomography-based criteria were proposed for diagnosing ABS in patients with ASDH and determining its incidence. Univariate and multivariate logistic regression analyses were performed to explore the risk factors of post-traumatic ABS. The Glasgow Outcome Scale (GOS) score, mortality, and functional prognosis of all patients at discharge and the proportion of intraoperative malignant brain bulge in surgical patients were taken as clinical outcome measures. Results: A total of 45 (28%) patients experienced post-traumatic ABS, exhibiting significantly lower Glasgow Coma Scale scores on admission (p < 0.001). The incidence of hemispheric and whole-brain swelling was 8.1% and 19.9%, respectively. Risk factors independently associated with post-traumatic ABS were: (1) age [odds ratio (OR) = 0.917, p < 0.001]; (2) platelet to white blood cell ratio (PWR) (OR = 0.887, p = 0.012); and (3) traumatic subarachnoid hemorrhage (SAH) (OR = 4.346, p = 0.005). The ABS cohort had a lower GOS score [2 (1-3) versus 4 (3-5); p < 0.001], higher mortality (46.7% versus 6.9%; p < 0.001), and higher proportion of unfavorable functional prognosis (75.6% versus 34.5%; p < 0.001) upon discharge compared to the no ABS cohort, along with higher proportion of intraoperative malignant brain bulge (43.8% versus 0%; p < 0.001). Conclusion: The incidence of ABS associated with ASDH is significantly high overall. Patients with ASDH who have young age, low PWR, and traumatic SAH are at an increased risk of developing post-traumatic ABS, and therefore of poor clinical outcomes.

ABSTRACT

Both alopecia areata (AA) and vitiligo are distinct, heterogenous, and complex disease entities, characterized by nonscarring scalp terminal hair loss and skin pigment loss, respectively. In AA, inflammatory cell infiltrates are in the deep reticular dermis close to the hair bulb (swarm of bees), whereas in vitiligo the inflammatory infiltrates are in the epidermis and papillary dermis. Immune privilege collapse has been extensively investigated in AA pathogenesis, including the suppression of immunomodulatory factors (e.g., transforming growth factor-ß (TGF-ß), programmed death-ligand 1 (PDL1), interleukin-10 (IL-10), α-melanocyte-stimulating hormone (α-MSH), and macrophage migration inhibitory factor (MIF)) and enhanced expression of the major histocompatibility complex (MHC) throughout hair follicles. However, immune privilege collapse in vitiligo remains less explored. Both AA and vitiligo are autoimmune diseases that share commonalities in pathogenesis, including the involvement of plasmacytoid dendritic cells (and interferon-α (IFN- α) signaling pathways) and cytotoxic CD8+ T lymphocytes (and activated IFN-γ signaling pathways). Blood chemokine C-X-C motif ligand 9 (CXCL9) and CXCL10 are elevated in both diseases. Common factors that contribute to AA and vitiligo include oxidative stress, autophagy, type 2 cytokines, and the Wnt/ß-catenin pathway (e.g., dickkopf 1 (DKK1)). Here, we summarize the commonalities and differences between AA and vitiligo, focusing on their pathogenesis.

ABSTRACT

OBJECTIVE: A cerebellar bulge prior to posterior fossa resection is an emergency condition during surgery. Intraoperative cerebellar bulging not only increases the difficulty of lesion resection but also brings additional postoperative complications. Currently, there are few systematic reports on this topic. The predictors of cerebellar bulge and how to effectively prevent intraoperative cerebellar bulge are discussed in this article. METHODS: The clinical and imaging data of 527 patients with posterior fossa lesions who underwent resection at our hospital were retrospectively collected and analyzed. Perioperative clinical and imaging data were assessed. Variables were analyzed using univariate and multivariate regression analyses. RESULTS: Overall, 10.4% (55/527) of patients had intraoperative acute bulges. Multivariate analysis revealed that age <60 years, body mass index ≥24, lesion size ≥30 (mm), cerebellar tonsillar herniation and/or hydrocephalus, and perilesional edema (moderate-severe) were predictors of cerebellar bulging. Relief of the cerebellar bulge can be accomplished by excising the lesion, releasing cerebrospinal fluid, and removing the cerebellum (the outer one-third). Obvious cerebellar-related complications occurred in 4 patients postoperatively, and the symptoms disappeared after 6 months of follow-up. CONCLUSIONS: Cerebellar bulging during intraoperative posterior fossa resection deserves attention. Through the analysis of multiple factors related to cerebellar bulge, comprehensive evaluation and early intervention during the perioperative period are necessary. The incidence of cerebellar bulges can be reduced, and surgical complications related to cerebellar bulges can be avoided.

ABSTRACT

DNA circuits based on successive toehold-mediated DNA displacement reactions, particularly entropy-driven DNA circuit (EDC) systems, have attracted considerable attention as powerful enzyme-free tools for dynamic DNA nanotechnology. However, background leakage (noise signal) often occurs when the circuit is executed nonspecifically, even in the absence of the appropriate catalyst DNA (input). This study designed and developed a new latent toehold-mediated DNA circuit (LDC) system that relies on a bulge-loop structure as a latent toehold toward leakage reduction. Furthermore, the number (size) of nucleotides (nt) in the bulge-loop is found to play a significant role in the performance (i.e., leakage, signal, and kinetics) of LDC systems. In fact, the signal rate for the LDC systems increased as the number of nt in the bulge-loop increased from 4 to 8, whereas the leakage rate of the LDC systems with bulge-loops of 7 nt or less was low, but the leakage rate of the LDC system with a bulge-loop of 8 nt increased significantly. Note that the LDC system with the optimal bulge-loop (7 nt) was capable of not only reducing the leakage but also accelerating the circuit speed without any signal loss, unlike methods of reducing the leakage by reducing the signal reported previously for the conventional EDC systems. These facts indicate that the 7 nt bulge-loop acts as a "latent" toehold for the DNA circuit system. By using the amplification function of output signals with an accelerated circuit and reduced leakage, our LDC system with a 7 nt bulge-loop could be applied directly and successfully to signal-amplifying DNA logic gates such as OR and AND gates, and thus, sufficient output signals could be obtained even with a small amount of input. These findings reveal that our LDC systems with a bulge-loop structure can replace the conventional EDC system and have enormous potential in the field of DNA nanotechnology.

ABSTRACT

Hair follicle stem cells (HFSCs) in the bulge are a multipotent adult stem cell population. They can periodically give rise to new HFs and even regenerate the epidermis and sebaceous glands during wound healing. An increasing number of biomarkers have been used to isolate, label, and trace HFSCs in recent years. Considering more detailed data from single-cell transcriptomics technology, we mainly focus on the important HFSC molecular markers and their regulatory roles in this review.

ABSTRACT

BACKGROUND: The deep inferior epigastric perforator (DIEP) free flap is the gold standard procedure for autologous breast reconstruction. Although breast-related complications have been well described, donor-site complications and contributing patient risk factors are poorly understood. METHODS: We examined a multi-institutional, prospectively maintained database of patients undergoing DIEP free flap breast reconstruction between 2015 and 2020. We evaluated patient demographics, operative details, and abdominal donor-site complications. Logistic regression modeling was used to predict donor-site outcomes based on patient characteristics. RESULTS: A total of 661 patients were identified who underwent DIEP free flap breast reconstruction across multiple institutions. Using logistic regression modeling, we found that body mass index (BMI) was an independent risk factor for umbilical complications (odds ratio [OR] 1.11, confidence interval [CI] 1.04-1.18, p = 0.001), seroma (OR 1.07, CI 1.01-1.13, p = 0.003), wound dehiscence (OR 1.10, CI 1.06-1.15, p = 0.001), and surgical site infection (OR 1.10, CI 1.05-1.15, p = 0.001) following DIEP free flap breast reconstruction. Further, immediate reconstruction decreases the risk of abdominal bulge formation (OR 0.22, CI 0.108-0.429, p = 0.001). Perforator selection was not associated with abdominal morbidity in our study population. CONCLUSIONS: Higher BMI is associated with increased abdominal donor-site complications following DIEP free flap breast reconstruction. Efforts to lower preoperative BMI may help decrease donor-site complications.

ABSTRACT

A degenerative disc disease is characterized by osteophytes, disc space reduction, nerve compression and discomfort are all symptoms of disc bulging. Diabetic neuropathy, a condition leading to significant health issues, involves a sensory dysfunction initiating in the lower extremities and progressing to pain. In the present case, a 61-year-old retired physical training teacher came to the hospital with complaints of difficulty in walking, sitting, and standing in the past two years. The patient also complained of a tingling sensation in the upper and lower limbs, low back pain, and body stiffness. The patient has a known case of intervertebral disc prolapse at L2-S1 level, two years back. Patient had a history of diabetes mellitus type 2, hypertension, and hypothyroidism for the past three years. The study delves into the detailed evaluation, customized treatment plan, and rehabilitation strategies employed to meet the patient's condition. It emphasizes the value of a multidisciplinary approach, including physical therapy, in the treatment of complicated musculoskeletal and neurological illnesses, intending to improve the patient's mobility, functionality, and overall quality of life.

ABSTRACT

Although structures of many RNA loops, such as GNRA and UNCG tetraloops, were well known, it is still possible to find more RNA structures. In the present study, solution structure of an RNA fragment having UUCGA pentaloop was analyzed by NMR spectroscopy. It was found that the UUCG tetraloop is formed and the adenosine residue at the 3' side of the tetraloop is bulged out. The characteristic motif of the loop-bulge structure has also been found in other RNAs including CUUGU and CUGGC pentaloops. Along with the recently found T-hairpin structure with a UUUGAUU loop, in which UUUGA pentaloop and UU bulge are formed, the loop-bulge structures can be categorized as an RNA motif and it may be called as the integrated structure loop, I-loop.

ABSTRACT

OBJECTIVE: The objective of this study was to evaluate whether early postpartum exercise is associated with changes in pelvic symptom severity, pelvic floor muscle strength, and diastasis recti abdominis (DRA) from 3 to 12 months postpartum. METHODS: In this prospective cohort study, 504 participants with and without pelvic symptoms (pelvic girdle pain, stress urinary incontinence, vaginal heaviness) were followed. At 3, 6, 9, and 12 months postpartum, we assessed pelvic symptoms, exercise behavior (by questionnaires), pelvic floor muscle strength (by vaginal palpation), and DRA (by caliper measurement). Based on the 3-months questionnaire, participants were categorized as nonexercisers (n = 105), minimal low-impact exercisers (n = 249), regular low-impact exercisers (n = 117), and high-impact exercisers (n = 32). Between-group differences and within-group changes from 3 to 12 months were calculated using Chi-square tests, Kruskal-Wallis tests, and Friedman analysis of variance. RESULTS: At 3 months, no differences in symptom prevalence were seen between the groups. Nonexercisers reported higher pelvic girdle pain severity and had weaker pelvic floor muscles. The within-group analysis showed that pelvic girdle pain severity did not change in nonexercisers or high-impact exercisers, but decreased in minimal and regular low-impact exercisers. Stress urinary incontinence increased in nonexercisers from 3 to 12 months, while it remained unchanged in regular low-impact and high-impact exercisers, and decreased in minimal low-impact exercisers. Across all groups, vaginal heaviness and DRA decreased, and pelvic floor strength increased from 3 to 12 months. CONCLUSION: The study indicates that early low-impact exercising is associated with reduced pelvic girdle pain severity during the first postpartum year. Minimal low-impact exercisers also showed a slight reduction in stress urinary incontinence. Conversely, nonexercisers reported an increase in stress urinary incontinence between 3 and 12 months postpartum. IMPACT: Physical therapists should encourage women to start with low-impact exercise early after pregnancy. LAY SUMMARY: This study highlights the positive effects of starting gentle, low-impact exercise early after childbirth to reduce pelvic girdle pain and urinary incontinence.

ABSTRACT

Nitrous oxide (N2O) is a unique anesthetic agent that has both advantages and disadvantages, especially in neurosurgical patients. Various studies evaluating the use of N2O in different surgical populations have been inconclusive so far. In this prospective, single-blinded, randomized study, 50 patients of either sex, aged 18-60 years, were enrolled and randomly allocated into N2O or N2O free group. Data including demographics, intraoperative vitals, blood gases, intravenous fluids, anesthetic drug consumption, brain condition, emergence and recovery time, duration of surgery and anesthesia, duration of postoperative ventilation, perioperative complications, condition at discharge, and duration of intensive care unit & hospital stay were recorded. There was no significant difference in intensive care unit or hospital stay between the groups. However, a significant difference in intraoperative heart rate and mean arterial pressure was observed. The incidence of intraoperative tachycardia and hypotension was significantly higher in the N2O free group. Other intra- and post-operative parameters, perioperative complications, and conditions at discharge were comparable. Use of N2O anesthesia for cerebellopontine tumor surgery in good physical grade and well-optimized patients neither increases the length of intensive care unit or hospital stay nor does it affect the complications and conditions at discharge. However, future studies in poor-grade patients with large tumors and raised intracranial pressure will be required to draw a definitive conclusion.

ABSTRACT

BACKGROUND: Parastomal hernias are a common consequence of stoma surgery and can occur in up to 50% of patients. They are mangaged either conservatively, through support hosiery, or surgically. A patient feasibility study called the Hernia Active Living Trial (HALT) was designed to examine if a clinical pilates-based exercise programme offers an alternative approach to managing a parastomal hernia or bulge. METHOD: Adults with an ileostomy or colostomy who perceived they had a bulge around their stoma were included in the study. The intervention included up to 12 online sessions of an exercise booklet and videos with an exercise specialist. Interviews were conducted to explore participants' experiences of the intervention. The interview data were analysed systematically and thematically. Participants were also asked to complete patient diaries every week. RESULTS: Twelve of the 13 participants who completed the intervention agreed to be interviewed. Following analysis, three main themes emerged including managing a hernia/bulge, benefits and barriers. Participants talked about the benefits of this programme including: reduction of the size of their hernia, increased abdominal control, body confidence and posture, as well as increased physical activity levels. The barriers described were generally overcome allowing participants to engage in what was perceived to be a positive and potentially life-changing experience. CONCLUSIONS: A clinical pilates-based exercise programme for people with a parastomal hernia can bring both direct and indirect improvements to a patient's hernia management, sense of wellbeing and day-to-day life. Individuals with a hernia should be informed about the need for, and value of, exercise to strengthen core muscles, as part of their non-surgical options for self-management.

ABSTRACT

INTRODUCTION/OBJECTIVES: Discrete upper septal thickening (DUST) is a phenotype of elderly people. The cardiac phenotype in senior cats has been incompletely described. We aimed to characterize the echocardiographic phenotype of senior cats, specifically to determine prevalence of DUST and hypertrophic cardiomyopathy (HCM). ANIMALS: One hundred and forty-nine healthy, normotensive cats. MATERIALS AND METHODS: Prospective cross-sectional study. Senior (≥9 years) and young (<6 years) cats were recruited from non-referral population. We defined DUST as an isolated basilar septal bulge, and HCM as left ventricular wall thickness ≥6 mm. An interventricular septum ratio (basal-to-mid septal thickness ratio) was calculated. We assessed for associations between clinical and echocardiographic variables and DUST. Data are presented as mean (±SD), median (range), or frequency (percentage). RESULTS: One-hundred and two senior and 47 young cats were enrolled. Aortoseptal angle (AoSA) was steeper in senior cats (137° (±14.5) vs. 145° (±12.3) in young cats, P=0.002). Eighteen cats had DUST (18/149, 12%), fourteen senior, and four young cats (P=0.4). Cats with DUST had steeper AoSA (125° (±8.3) vs. 142° (±13.7), P<0.0001) and higher interventricular septum ratio (1.4 (1.2-2.0) vs. 1.0 (0.7-1.8)). Univariable analysis showed decreased odds of DUST with greater AoSA (OR 0.9, P<0.0001), age was not associated with DUST. Twenty-nine senior cats had HCM (28.4%). DISCUSSION/CONCLUSIONS: Prevalence of DUST was 12%. There was no association between age and DUST. Smaller/steeper AoSA was the main factor associated with DUST. There was a high prevalence of HCM in this senior population.

ABSTRACT

AIM: The aim was to investigate patients' experiences of being prepared for the development of a parastomal bulge in relation to a stoma. METHODS: The paper draws on a qualitative interview study conducted with 20 Danish patients participating in five focus groups. Analysis was performed using a phenomenological-hermeneutic approach. RESULTS: We identified three themes. The first theme is 'The unforeseen bulge gives rise to increasing concern and a search for an explanation'. Patients searched for explanations in their own life and suspected that their behaviour or previous illness induced the bulge. The second theme is 'Missing or confusing information leads to counterproductive behaviour'. Patients lacked information on the prevention and treatment of parastomal bulging which led to disappointment with healthcare professionals. The third theme is 'Weighing the pros and cons of life with the bulge against the gamble of surgical repair'. Some patients came to terms with their situation, but for others a deadlocked situation arose when surgical repair was not an option. CONCLUSION: Healthcare communication directly impacts on patients' experiences and outcomes. When unprepared for the emergence of a parastomal bulge, patients' emotional and psychological well-being are affected and likewise patients' possibility of using their own health beliefs as a preventive strategy. To preserve patient autonomy, satisfaction and well-being, surgeons and stoma nurses should provide patients with tailored information bearing in mind the current lack of clear evidence on the prevention and treatment of parastomal bulging.

ABSTRACT

BACKGROUND: Intravitreal anti-vascular endothelial growth factor (VEGF) is a mainstream treatment for reducing ME secondary to BRVO (BVO-ME). Regrettably, most reports of intravitreal anti-VEGF for BVO-ME have disclosed only short-term outcomes. Here, we characterized long-term indicators for the visual prognosis of patients with BVO-ME, including the correlation between retinal structure by OCT and visual acuity. METHODS: Patients with BVO-ME were retrospectively recruited based on clinical records in Kansai Medical University Hospital from June 2012 to March 2022. This study enrolled patients with vision loss who received intravitreal injection of anti-VEGF for BVO-ME. Inclusion criteria were that patients received intravitreal injection of anti-VEGF as their first treatment and were followed for at least 36 months. Exclusion criteria were those patients with ocular disease other than BRVO or who had been previously treated for BVO-ME. Patients were divided into two groups according to BCVA at the final visit: Group A (≥ 0.7) and Group B (< 0.7). RESULTS: Forty-seven eyes from 45 patients were assessed. The mean follow-up period from initial to final visit was 64.38 ± 15.07 (range, 38-100) months. BCVA in Group A (n = 32) was significantly greater than in Group B (n = 15) at all timepoints. The ratio that the number of eyes which the EZ band and the foveal bulge were intact in Group A was higher than in Group B (p = 0.0004 and p = 0.0002, respectively). The ratio that the number of eyes which recurrence SRD was observed by the final visit in Group A was lower than in Group B (p = 0.0485). CONCLUSIONS: The integrity of the EZ band and an intact foveal bulge were significant predictors for visual acuity. In contrast, recurrent SRD led to poor visual acuity in the long term, even if BCVA was good in the short term.

ABSTRACT

When several continuous guanine runs are present closely in a nucleic acid sequence, a secondary structure called G-quadruplex can form (G4s). Such structures in the genome could serve as structural and functional regulators in gene expression, DNA-protein binding, epigenetic modification, and genotoxic stress. Several types of G4-forming DNA sequences exist, including bulged G4-forming sequences (G4-BS). Such bulges occur due to the presence of non-guanine bases in specific locations (G-runs) in the G4-forming sequences. At present, search algorithms do not identify stable G4-BS conformations, making genome-wide studies of G4-like structures difficult. Data provided in this study are related to a published article "Stable bulged G-quadruplexes in the human genome: Identification, experimental validation and functionalization" published by Nucleic Acids Research [DIO.org/10.193/nar/gkad252]. Based on our studies in vitro and G4-seq and G4 CUT&Tag data analysis, we have specified and validated three pG4-BS models. In this article, a large collection of 'raw' (unfiltered) dataset is presented, which includes three subfamilies of pG4-BS. For each of pG4-BS, we provide strand-specific genomic boundaries. Data on pG4-BS might be useful in elucidating their structural, functional, and evolutionary roles. Furthermore, they may provide insight into the pathobiology of G4-like structures and their potential therapeutic applications.

ABSTRACT

Background: Compression therapy using compression material is often used for umbilical hernias in infants; however, there are problems regarding its use, such as appearance and cost. In our hospital, we use the tape fixation method without compression materials. We report the effectiveness of this method, its significance in measuring the degree of hernia bulge before treatment, and parent satisfaction with the treatment. Methods: We analyzed 77 cases of umbilical hernias (41 boys and 36 girls, mean age 52.7 ± 18.3 days) that were treated with the tape fixation method at the Department of Pediatrics of our hospital. Hernia size was classified based on the height of the bulge: mild (<1 cm), moderate (1≦ and <3 cm), or severe (>3 cm). Treatment duration was compared between the groups using the Steel-Dwass test. After the treatment, a questionnaire was mailed to the parents to assess the treatment satisfaction. Results: Seventy-three patients (94.8%) achieved closure of the hernia orifice, with no excess skin and a well-shaped umbilicus. The duration of treatment was significantly shorter, with the following order: mild (18.5 ± 8.2 days), moderate (25.0 ± 11.9 days), and severe cases (47.8 ± 11.7 days). According to the questionnaire, 97.5% of the parents were satisfied with the treatment. Conclusions: Our tape fixation method without compression material achieved a high closure rate and a good shape of the umbilicus. In addition, we noted that the height of the hernia bulge can be used as a guide to estimate the duration of treatment.

ABSTRACT

OBJECTIVE: Annular fissures are common findings on MR studies of the lumbar spine but have not been specifically examined in the thoracic spine. We sought to review the prevalence and stability of MRI imaging features of thoracic annular fissures and the association of thoracic AFs with intervertebral degenerative disk changes. MATERIALS AND METHODS: We surveyed 10 years of MRI studies in which patients had one or more repeated examinations of the thoracic spine. For every annular fissure, we recorded its imaging features on all pulse sequences and the evolution of those imaging findings across all time periods. RESULTS: We reviewed 210 patients and discovered that 66 (31.4%) had at least one thoracic annular fissure. The presence of annular fissures was positively correlated with older age and male gender. The initial annular fissure was always hyperintense on T2WI and annular fissures remained hyperintense on T2WI over time in all cases but showed less hyperintensity in 23.9% (n = 39/163) and more hyperintensity in 4.9% (n = 8/163). The rate of concomitant disk bulges was 85.8% (n = 140/163). Of the 71 annular fissures in which gadolinium-enhanced studies were performed, 20 (28.1%) showed enhancement and 14/20 (70%) annular fissures showed persistent enhancement over time (mean follow-up = 39.6 ± 44.1 months). CONCLUSION: Thoracic annular fissures rarely resolve, remain hyperintense on T2WI, and, if they enhance, that enhancement generally persists.
