ABSTRACT

Alterations in cognitive and non-cognitive cerebral functions characterize Alzheimer's disease (AD). Cortical and hippocampal impairments related to extracellular accumulation of Aß in AD animal models have been extensively investigated. However, recent reports have also implicated intracellular Aß in limbic regions, such as the nucleus accumbens (nAc). Accumbal neurons express high levels of inhibitory glycine receptors (GlyRs) that are allosterically modulated by ethanol and have a role in controlling its intake. In the present study, we investigated how GlyRs in the 2xTg mice (AD model) affect nAc functions and ethanol intake behavior. Using transgenic and control aged-matched litter mates, we found that the GlyRα2 subunit was significantly decreased in AD mice (6-month-old). We also examined intracellular calcium dynamics using the fluorescent calcium protein reporter GCaMP in slice photometry. We also found that the calcium signal mediated by GlyRs, but not GABAAR, was also reduced in AD neurons. Additionally, ethanol potentiation was significantly decreased in accumbal neurons in the AD mice. Finally, we performed drinking in the dark (DID) experiments and found that 2xTg mice consumed less ethanol on the last day of DID, in agreement with a lower blood ethanol concentration. 2xTg mice also showed lower sucrose consumption, indicating that overall food reward was altered. In conclusion, the data support the role of GlyRs in nAc neuron excitability and a decreased glycinergic activity in the 2xTg mice that might lead to impairment in reward processing at an early stage of the disease.

ABSTRACT

As the number of Internet users grows, the increase in smart devices interconnected through the Internet of Things (IoT) have contributed to improvements in the functionality of everyday products and enhancement of user experience. Yet, they affect user privacy and render personal data more vulnerable. To foster a digital future fully aware of user privacy requirements, a line of design research emerges that focuses on balancing product innovation with user data protection. This matter relates to sociocultural, economic, and technological aspects, and its core is a human-centered design strategy. Still, there is a gap in academic research oriented towards guiding product developers on how to consider personal data privacy concerns when designing honest IoT devices. To define this gap and delve deeper into this relevant topic, this paper presents a systematic literature review of recent academic research using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. This review focuses on prevalent research topics such as data privacy, personal data, data surveillance, and user behaviour in IoT. The result is a state-of-the-art compilation of 45 scientific studies mapping the most relevant concepts and approaches for product development in the last ten years of research, aligned with some central research questions. The Discussion and Conclusion sections provide a deep understanding of the complexity of the fast-changing landscape of privacy and personal data management using IoT products. Finally, this study proposes future academic research directions devoted to providing product designer specific, specialised help from different (yet interconnected) scientific approaches.

ABSTRACT

Blooming and pruning is one of the most important developmental mechanisms of the biological brain in the first years of life, enabling it to adapt its network structure to the demands of the environment. The mechanism is thought to be fundamental for the development of cognitive skills. Inspired by this, Chialvo and Bak proposed in 1999 a learning scheme that learns from mistakes by eliminating from the initial surplus of synaptic connections those that lead to an undesirable outcome. Here, this idea is implemented in a neuromorphic circuit scheme using CMOS integrated HfO2-based memristive devices. The implemented two-layer neural network learns in a self-organized manner without positive reinforcement and exploits the inherent variability of the memristive devices. This approach provides hardware, local, and energy-efficient learning. A combined experimental and simulation-based parameter study is presented to find the relevant system and device parameters leading to a compact and robust memristive neuromorphic circuit that can handle association tasks.

ABSTRACT

Introduction and importance: Acquired von Willebrand disease (AvWD) is a rare underdiagnosed bleeding disorder caused by alterations in the levels of the major blood-clotting protein von Willebrand factor (vWF). The clinical and laboratory parameters of AvWD are similar to congenital vWD, but it is found in individuals with no positive family history with no underlying genetic basis. The disease remains multifactorial and incompletely understood. Proposed mechanisms include the development of autoantibodies to vWF, absorption of high molecular weight vWF multimers that impair normal function, shear stress induced vWF cleavage and increased proteolysis.The aetiology of the disease is variable, the most common being hematoproliferation, lymophoproliferation, myeloproliferation and autoimmune and cardiovascular disorders. Consensus and protocols for AvWD patients that require major surgery are currently lacking. Patients with AvWD can experience thrombotic events during surgery as a result of therapeutic interactions with pro-thrombotic risk factors. Case presentation: Here, the authors report a patient with AvWD requiring a knee prosthesis implantation due to chronic pain, limited range of motion and functional impairment. The patient had a high risk of bleeding during surgery and was at risk of thrombosis due to age and obesity. Clinical discussion: Perioperative care required a collaborative approach and the management of bleeding. The patient was administered vWF concentrate Willfact lacking Factor VIII to prevent haemorrhage and to minimize the risk of thrombosis. Conclusion: The treatment was effective and well-tolerated. The authors use this information to provide recommendations for AvWD patients for whom major surgery is indicated.

ABSTRACT

INTRODUCTION/OBJECTIVES: The addition of a boost to the lumpectomy bed after whole-breast (WB) radiotherapy plays a key role in the treatment of patients with breast cancer (BC). The clinical benefits of a boost with high-dose-rate brachytherapy (HDR-BT) after conventional fractionation is supported by a large body of evidence. However, few studies have described its outcomes after a hypofractionated scheme. MATERIALS AND METHODS: We included all patients treated with adjuvant WB-IMRT in 15 sessions followed by a single-session HDR-BT boost with local anesthesia on an outpatient basis. RESULTS: Between 2009 and 2017, 638 patients with early-stage BC were treated according to the aforementioned protocol after breast-conserving surgery. Median follow-up was 6 years (4-11). Despite the low incidence of side effects and their slightness, we did identify an impact of breast volume on the risk of acute radiodermatitis, fibrosis, pain and edema. However, we did not identify any relationship between the volume in cubic centimeters of the BT-implant with acute or long-term side effects. 2.2% patients had an actual local relapse, 2.4% a 2nd primary in the same breast and 2.39% were diagnosed with contralateral BC. Event-free survival at 11 years was 85.5% with an overall survival of 95.7%. CONCLUSION: Adjuvant hypofractionated whole-breast IMRT followed by a single dose HDR-BT boost has a low incidence of acute and chronic toxicity and excellent oncological outcomes. However, it may be worthwhile to intensify self-care protocols and surveillance in women with large breasts who may be at increased risk of side effects.

ABSTRACT

PURPOSE: We aimed to describe the clinical, immunological, and genetic features of patients with DOCK8 deficiency (DOCK8-Def) in a tertiary care center for children. METHODS: Retrospective chart review of patients' clinical, immunological, and genetic characteristics with DOCK8-Def. Genetic analysis was performed with targeted- or whole-exome sequencing; we also assessed DOCK8 protein expression and a lymphoproliferation assay and analyzed survival by the Kaplan-Meier method. RESULTS: We described 11 patients from 8 unrelated kindreds. The median age at symptoms' onset was 10 months (range 1-54 months). The median follow-up time was 53.4 months (4.8-118.8). All patients presented eczema and recurrent sinopulmonary and cutaneous infections. Besides those symptoms, the most frequent manifestations were bronchiectases (8/11), food allergies (6/11), and severe infections (6/11). Infrequent characteristics were detection of CMV in bronchial lavage, C. parvum-driven sclerosing cholangitis, Takayasu vasculitis, neurological syndromes, pulmonary tuberculosis, and lymphomatoid granulomatosis. CONCLUSION: DOCK8-Def has a broad spectrum of manifestations, including allergy, autoimmunity, inflammation, infection, and cancer. The hallmark of this inborn error of immunity is IEI-associated eczema with eosinophilia and increased IgE. Here, we report six new mutations causing human DOCK8 deficiency and symptoms previously unrecognized to occur in DOCK8-Def. Therefore, an early diagnosis of DOCK8-Def is essential to facilitate an adequate treatment such as HSCT.

ABSTRACT

PURPOSE: Pectus excavatum (Pectus) repair may be offered for those with significant cardiopulmonary compromise or severe cosmetic defects. The influence of hospital center volume on postoperative outcomes in children is unknown. This study aimed to investigate the outcomes of children undergoing Pectus repair, stratified by hospital surgical volume. METHODS: The Nationwide Readmission Database was queried (2016-2020) for patients with Pectus (Q67.6). Patients were stratified into those who received repair at high-volume centers (HVCs; ≥20 repairs annually) versus low-volume centers (LVCs; <20 repairs annually). Demographics and outcomes were analyzed using standard statistical tests. RESULTS: A total of 9414 patients with Pectus underwent repair during the study period, with 69% treated at HVCs and 31% at LVCs. Patients at LVCs experienced higher rates of complications during index admission, including pneumothorax (23% vs. 15%), chest tube placement (5% vs. 2%), and overall perioperative complications (28% vs. 24%) compared to those treated at HVCs, all p < 0.001. Patients treated at LVCs had higher readmission rates within 30 days (3.8% vs. 2.8% HVCs) and overall readmission (6.8% vs. 4.7% HVCs), both p < 0.010. Among readmitted patients (n = 547), the most frequent complications during readmission for those initially treated at LVCs included pneumothorax/hemothorax (21% vs. 8%), bar dislodgment (21% vs. 12%), and electrolyte disorders (15% vs. 9%) compared to those treated at HVCs. CONCLUSION: Pediatric Pectus repair performed at high-volume centers was associated with fewer index complications and readmissions compared to lower-volume centers. Patients and surgeons should consider this hospital volume-outcome relationship. TYPE OF STUDY: Retrospective Comparative. LEVEL OF EVIDENCE: III.

ABSTRACT

PURPOSE: Motor vehicle collisions (MVC) are the second leading cause of death in children and adolescents, but appropriate restraint use remains inadequate. Our previous work shows that about half of pediatric MVC victims presenting to our trauma center were unrestrained. This study evaluates restraint use among children and adolescents who did not survive after MVC. We hypothesize that restraint use is even lower in this population than in pediatric MVC patients who reached our trauma center. METHODS: We reviewed the local Medical Examiner's public records for fatal MVCs involving decedents <19 years old from 2010 to 2021. When restraint use was not documented, local Fire Rescue public records were cross-referenced. Patients were excluded if restraint use was still unknown. Age, demographics, and restraint use were compared using standard statistical methods. RESULTS: Of 199 reviewed cases, 92 met selection criteria. Improper restraint use was documented in 72 patients (78%). Most decedents were White (72% versus 28% Black) and male (74%), with a median age of 17 years [15-18]. Improper restraint use was more common among Black (92% vs 73% White, p = 0.040) and male occupants (85% vs 58% female, p = 0.006). Improper restraint use was lower in the Hispanic population (73%) compared to non-Hispanic individuals (89%), but this difference was not statistically significant (p = 0.090). CONCLUSION: Most pediatric patients who die from MVCs in our county are improperly restrained. While male and Black patients are especially high-risk, the overall dismal rates of restraint use in our pediatric population present an opportunity to improve injury prevention measures. TYPE OF STUDY: Retrospective Comparative Study. LEVEL OF EVIDENCE: Level III.

ABSTRACT

Consumers prefer food products that, in addition to nutritional properties, also have effects beneficial to health. Non-conventional food plants such as canary seed (Phalaris canariensis) constitute an alternative in the food industry due to nutritional properties, chemical, and bioactive potential. The aim of this research was to develop pancake formulations with the inclusion of canary seed flour to evaluate their proximate composition, overall score, taste and texture sensory acceptability, and glycemic index. Pancakes based on whole-wheat flour mixed with canary seed flour were developed at four substitution levels (control 0, 10, 30, and 50%). The formulations exhibited attractive nutritional properties, mainly due to the levels of protein (~ 8.7%), minerals (~ 5.1%), and total dietary fiber (4.7-5.9%). The overall score and taste showed a statistical difference (p < 0.05) between the formulations. The flours with 10 and 30% showed high sensory acceptability with scores of 6.22 and 6.67 respect to 7-point hedonic scale, between the categories "I like it" and "I like it a lot". All formulations presented a low glycemic index (34-39%) that was significantly influenced (p < 0.05) as the level of substitution increased. The findings represent a new approach to the use of canary seed in the development of healthy food products.

ABSTRACT

BACKGROUND: Previous studies have shown improved survival for severely injured adult patients treated at American College of Surgeons verified level I/II trauma centers compared to level III and undesignated centers. However, this relationship has not been well established in pediatric trauma centers (PTCs). We hypothesize that severely injured children will have lower mortality at verified level I/II PTCs compared to centers without PTC verification. METHODS: All patients 1-15 years of age with ISS >15 in the 2017-2019 American College of Surgeons Trauma Quality Programs (ACS TQP) dataset were reviewed. Patients with pre-hospital cardiac arrest, burns, and those transferred out for ongoing inpatient care were excluded. Logistic regression models were used to assess the effects of pediatric trauma center verification on mortality. RESULTS: 16,301 patients were identified (64 % male, median ISS 21 [17-27]), and 60 % were admitted to verified PTCs. Overall mortality was 6.0 %. Mortality at centers with PTC verification was 5.1 % versus 7.3 % at centers without PTC verification (p < 0.001). After controlling for injury mechanism, sex, age, pediatric-adjusted shock index (SIPA), ISS, arrival via interhospital transfer, and adult trauma center verification, pediatric level I/II trauma center designation was independently associated with decreased mortality (OR 0.72, 95 % CI 0.61-0.85). CONCLUSIONS: Treatment at ACS-verified pediatric trauma centers is associated with improved survival in critically injured children. These findings highlight the importance of PTC verification in optimizing outcomes for severely injured pediatric patients and should influence trauma center apportionment and prehospital triage. LEVEL OF EVIDENCE: Level IV - Retrospective review of national database.

ABSTRACT

PURPOSE: The incidence of pulmonary embolism (PE) in hospitalized children has increased in recent years. This study sought to characterize factors and outcomes associated with PE using a national pediatric cohort. METHODS: The Nationwide Readmissions Database was queried (2016-2018) for patients (<18 years) with a diagnosis of PE. Index and prior hospitalizations (PHs) within 1 year were analyzed. A binary logistic regression utilizing 37 covariates (demographics, procedures, comorbidities, etc.) was constructed to examine a primary outcome of in-hospital mortality. RESULTS: 3440 patients were identified (57% female) with the majority >12 years old (77%). One-third had a known deep vein thrombosis (69% lower and 31% upper extremity). Nineteen percent underwent central venous catheter (CVC) placement. Twenty-one percent had a PH within 1 year. Nine percent underwent an operation with the majority being cardiothoracic (5%). Overall mortality was 5%. Neurocranial surgery, cardiothoracic surgery, and CVC placement were associated with the highest odds of inpatient mortality after logistic regression. CONCLUSION: Pediatric patients with PE have a high rate of PHs, CVC placement, and inpatient operations, which may be associated with higher mortality. This information can be utilized to improve screening measures and clinical suspicion for PE in hospitalized children.

ABSTRACT

PURPOSE: Although total oophorectomy (TO) was historically performed in cases of nonviable-appearing ovaries, considerable evidence has demonstrated equivalent outcomes after ovarian sparing surgery (OSS) as well as long-term fertility preservation benefits. This study sought to compare outcomes of OSS and TO for patients with ovarian torsion. METHODS: Females <21 years old admitted for ovarian torsion were identified from the Nationwide Readmissions Database (2016-2018) and stratified by OSS or TO. Propensity score-matched analysis (PSMA) utilizing >50 covariates (demographics, medical comorbidities, ovarian diagnoses, etc.) was constructed between those receiving TO and OSS. RESULTS: There were 3,161 females (median 15 [12-18] years) with ovarian torsion, and concomitant pathologies included cysts (42%), benign masses (25%), and malignant masses (<1%). Open approaches were more common (52% vs. 48% laparoscopic), and ovarian resection (OSS or TO) was performed in 87% (39% OSS and 48% TO). OSS was more commonly performed with laparoscopic detorsions (60% vs. 40% TO), while TO was more frequent in open operations (59% vs. 41% TO; both p < 0.001). No differences in overall readmissions (7% OSS vs. 8% TO) or readmissions for recurrent torsion (<1% overall) and ovarian masses (<1%) were observed (both groups <1%; p = 0.612). After PSMA, laparoscopy was still utilized less frequently with TO (39% vs. 53%; p < 0.001) despite similar rates of malignant masses. CONCLUSIONS: Overall, these data offer additional support for the current practice guidelines that give preference to OSS as the primary method of treatment for pediatric ovarian torsion in the majority of cases. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Retrospective Comparative Study.

ABSTRACT

INTRODUCTION: Cryptorchidism is commonly treated with orchiopexy at 6-12 months of age, often allowing time for undescended testicle(s) (UT) to descend spontaneously. However, when an inguinal hernia (IH) is also present, some surgeons perform orchiopexy and inguinal hernia repair (IHR) immediately rather than delaying surgery. We hypothesize that early surgical intervention provides no benefit for newborns with both IH and UT. METHODS: The Nationwide Readmissions Database was used to identify newborns with diagnoses of both IH and UT from 2010 to 2014. Patients were stratified by management: IHR performed on initial admission (Repair) or not (Deferral). Demographics, outcomes, and complications were compared. Results were weighted for national estimates. RESULTS: We analyzed 1306 newborns (64% premature) diagnosed with both IH and UT. IHR was performed at index admission in 30%. Repair was more common in premature babies (43% vs. 8% full-term, p < 0.001) and patients with congenital anomalies (33% vs. 27% without congenital anomaly, p = 0.012). There was no difference in readmission rates. Repair patients had higher rates of orchiectomy than did Deferral. No Deferral patients were readmitted for bowel resection, and <1% were readmitted for orchiectomy or hernia incarceration. CONCLUSION: In newborns with UT and IH, immediate repair is not associated with improved outcomes. Even with incarceration on initial presentation, rates of readmission with incarceration or bowel compromise for patients who undergo Deferral of surgery are minimal. Moreover, Repair newborns have higher rates of orchiectomy. We found no benefit to early operative intervention; thus, we recommend waiting until 6-12 months of age to reassess for surgery. LEVEL OF EVIDENCE: Level III TYPE OF STUDY: Retrospective Comparative Study.

ABSTRACT

OBJECTIVE: Pediatric firearm injuries (PFI) are a public health crisis. Little is known about how injury intent may influence the outcome of pediatric cranial firearm injuries (PCFI). The current study sought to compare demographics and outcomes of PCFI based on intent of injury. METHODS: The Nationwide Readmission Database (2010-2014) was queried to identify patients <18 years old with PCFI. Demographics and outcomes were compared by injury intent (assault, self-inflicted, unintentional), and results were weighted for national estimates to create a population-based cohort study. RESULTS: There were 1,365 cases of PCFI identified for an incidence of 11% of all PFI. The majority of patients were male (83 %), >13 years (81 %), and had an injury severity score >15 (79 %). Overall PCFI mortality was 43 %, compared to 6 % for all PFI. Assault was the most common intent (51 %), followed by self-inflicted (25 %), and unintentional (24 %). Assault was more likely to occur in patients from low-income households (61 % vs. 31 % self-inflicted vs. 42 % unintentional), p < 0.001. Unintentional injuries occurred in those <13 years old (40 % vs. 12 % assault vs. 16 % self-inflicted) and more often resulted in facial fracture (19 % vs. 11 % vs. 13 %), all p < 0.001. Readmission rate within the year was 21 %. The majority (56 %) of readmissions were unplanned, and the rate was highest for assault (77 % vs. <1 % self-inflicted vs. 44 % unintentional, p < 0.001). CONCLUSIONS: PCFI are associated with significant morbidity and mortality. Demographics and outcomes vary by intent of injury; knowledge of these patterns can direct future interventions to reduce injuries and impact outcomes.

ABSTRACT

INTRODUCTION: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects 3% of children in the world. OBJECTIVE: In this work, we seek to compare the different brain activations of pediatric patients with and without ADHD. METHODS: A functional resonance examination with BOLD contrast was applied using the MOXO-CPT test (Continuous Performance test with single and double visual-auditory distractors). RESULTS: Differences in BOLD activation were observed indicating that control children regularly presented negative BOLD activations that were not found in children with ADHD. Inhibitory activity in audiovisual association zones in control patients was greater than in patients with ADHD. The inhibition in the frontal and motor regions in the controls contrasted with the overactivation of the motor areas in patients with ADHD, this, together with the detection of cerebellar activation which attempted to modulate the responses of the different areas that lead to executive failure in patients with ADHD. CONCLUSIONS: In view of these results, it can be argued that the lack of inhibition of ADHD patients in their executive functions led to a disorganization of the different brain systems.

ABSTRACT

BACKGROUND: Gluteal augmentation with autologous fat transfer is one of the fastest growing aesthetic surgical procedures worldwide over the past decade. However, this procedure can be associated with high mortality from fatal pulmonary fat embolism events caused by intramuscular injection of fat. Ultrasound-guided fat grafting allows visualization of the transfer in the subcutaneous space, avoiding intramuscular injection. OBJECTIVES: The aim of this study was to assess the safety and efficacy of gluteal fat grafting performed with ultrasound-guided cannulation. METHODS: A retrospective chart review of all patients undergoing ultrasound-guided gluteal fat grafting at the authors' center between 2019 and 2022 was performed. All cases were performed by board-certified and board-eligible plastic surgeons under general anesthesia in ASA Class I or II patients. Fat was only transferred to the subcutaneous plane when over the gluteal muscle. Patients underwent postoperative follow-up from a minimum of 3 months up to 2 years. Results were analyzed with standard statistical tests. RESULTS: The study encompassed 1815 female patients with a median age of 34 years. Controlled medical comorbidities were present in 14%, with the most frequent being hypothyroidism (0.7%), polycystic ovarian syndrome (0.7%), anxiety (0.6%), and asthma (0.6%). Postoperative complications occurred in 4% of the total cohort, with the most common being seroma (1.2%), local skin ischemia (1.2%), and surgical site infection (0.8%). There were no macroscopic fat emboli complications or mortalities. CONCLUSIONS: These data suggest that direct visualization of anatomic plane injection through ultrasound guidance is associated with a low rate of complications. Ultrasound guidance is an efficacious adjunct to gluteal fat grafting and is associated with an improved safety profile that should be considered by every surgeon performing this procedure.

ABSTRACT

INTRODUCTION: In pediatric patients, incarcerated inguinal hernias are often repaired on presentation. We hypothesize that in appropriate patients, repair may be safely deferred. METHODS: The Nationwide Readmissions Database was used to identify pediatric patients (aged < 18 y) with incarcerated inguinal hernia from 2010 to 2014. Patients were stratified by management approach (Early Repair versus Deferral). Overall frequencies of these operative strategies were calculated. Propensity score matching was then performed to control for patient age, comorbidities, perinatal conditions, and congenital anomalies. Outcomes including complications, surgical procedures, and readmissions were compared. Outpatient surgeries were not assessed. RESULTS: Among 6148 total patients with incarcerated inguinal hernia, the most common strategy was to perform Early Repair (88% versus 12% Deferral). Following propensity score matching, the cohort included 1288 patients (86% male, average age 1.7 ± 4.1 years). Deferral was associated with equivalent rates of readmission within one year (13% versus 15%, P = 0.143), but higher readmissions within the first 30 days (7% versus 3%, P = 0.002) than Early Repair. Deferral patients had lower rates of orchiectomy (2% versus 5%, P = 0.001), wound infections (< 2% versus 2%, P = 0.020), and other infections (7% versus 15%, P < 0.001). The frequency of other complications including bowel resection, oophorectomy, testicular atrophy, sepsis, and pneumonia were equivalent between groups. Three percent of Deferrals had a diagnosis of incarceration on readmission. CONCLUSIONS: Deferral of incarcerated inguinal hernia repair at index admission is associated with higher rates of hospital readmissions within the first 30 days but equivalent readmission within the entire calendar year. These patients are at risk of repeat incarceration but have significantly lower rates of orchiectomy than their counterparts who undergo inguinal hernia repair at the index admission. We propose that prospective studies be performed to identify good candidates for Elective Deferral following manual reduction and overnight observation. Such studies must capture outpatient surgical outcomes.

ABSTRACT

BACKGROUND Tarsometatarsal joint (TMJ) arthrodesis is common method used for correcting hallux abductus valgus (HAV). Its popularity has grown due to studies revealing HAV's triplanar deformity with frontal plane rotation. This case report presents a 28-year-old woman with Down syndrome, congenital heart disease, and a history of knee surgery and plantar fasciitis, with severe HAV deformity and flexible valgus flatfoot associated with ligamentous hyperlaxity. CASE REPORT Examination revealed severe foot deformities, and radiographic studies confirmed the condition. A surgical intervention was planned, and the patient's cardiologist confirmed she was fit for the procedure. The modified Lapidus technique with frontal plane rotational correction included realigning the metatarsal joint, resecting spurs, osteosynthesis material, and arthrosis in the sinus tarsi. After surgery, the patient underwent a recovery period without support for 8 weeks and received appropriate medical care. Radiographs showed successful alignment, and the patient gradually resumed her daily activities. The patient had an uneventful recovery, and postoperative radiographs showed good alignment in all planes. CONCLUSIONS The hyperlaxity associated with Down syndrome makes the incidence of HAV more frequent, and TMJ fusion is preferable to correction by osteotomy. The modified Lapidus technique with frontal plane rotational correction could be a good technique to achieve satisfactory correction in patients with severe HAV deformity and flexible valgus flatfoot associated with ligamentous hyperlaxity. TMJ fusion is indicated when severe or recurrent rotational component is observed in X-rays.
