- Feasibility of Magnetic Resonance Angiography in Patients With Legg-Calve-Perthes Disease(2021) GRANGEIRO, Patricia Moreno; RODRIGUES, Joao C.; ANGELI, Luiz R. A. de; LEAO FILHO, Hilton; MONTENEGRO, Nei B.; GUARNIERO, Roberto; DEMPSEY, Molly; KIM, Harry K. W.Background: The etiology of Legg-Calve-Perthes disease (LCPD) remains unknown; however, interruption of medial circumflex femoral artery (MCFA) supply to the femoral head is the key pathogenic factor. The main purpose of this study is to determine the feasibility of using magnetic resonance angiography (MRA) to evaluate the course of the MCFA in the normal and affected hips of patients with unilateral LCPD. Methods: We analyzed 24 patients with unilateral LCPD using a time-resolved imaging of contrast kinetics magnetic resonance angiography (TRICKS-MRA). The course of the MCFA was divided into 4 segments in the coronal plane and in 3 segments in the axial plane, based on its location with respect to the femoral neck. The visibility of each segment was studied in the normal and affected sides. The segments were defined as not visible when no contrast was seen within the vessel lumen or visible when the lumen was partially or completely visualized with contrast. The statistical analysis was done using the chi(2) test. Results: TRICKS-MRA provided well-defined images of the first 2 segments of the MCFA on both the normal and affected sides of patients with LCPD (P=1). In half of the patients, the third segment was also visible using TRICKS-MRA on both sides (P=1). The fourth segment of the MCFA, which was the ascending lateral epiphyseal segment, was not visible on either side (P=0.49). No significant difference was found between the normal and affected hips in terms of visibility of the 4 segments of the MCFA using TRICKS-MRA. Anastomosis of the MCFA with the inferior gluteal artery was found in 3 hips (2 hips with LCPD and 1 normal hip). Conclusions: TRICKS-MRA provides well-defined images of the arterial supply to the proximal femoral epiphysis in children with LCPD, presenting a noninvasive and radiation-free alternative to conventional angiography. However, the TRICKS-MRA method used did not allow visualization of the ascending lateral epiphyseal segment of MCFA in the affected and the contralateral normal side. We believe that further advancement of this noninvasive imaging technique may open new opportunities for research aimed at evaluating the vascular supply of the femoral head in children.
- Congenital Clubfoot - Is the Ponseti Method the Definitive Solution?(2021) CORDEIRO, Felippi Guizardi; MACEDO, Rodrigo Sousa; MASSA, Bruno Sérgio Ferreira; GRANGEIRO, Patricia Moreno; GODOY-SANTOS, Alexandre Leme; FERNANDES, Túlio DinizAbstract Congenital clubfoot is one of the most common deformities at birth. The inadequacy or absence of treatment causes serious limitations for people with this condition. The initial treatment using the Ponseti method ensures functional results superior to other treatment modalities previously proposed. However, recurrences and neglected feet are still a challenge today. An understanding of the pathophysiology of the disease, as well as of the anatomy and local biomechanics and a thorough clinical and radiological evaluation of patients are essential to understanding the limits of the method and choosing the best treatment.
- REPRODUCIBILITY OF MODIFIED WALDENSTROM CLASSIFICATION IN PERTHES DISEASE(2021) CORDEIRO, Felippi Guizardi; GRANGEIRO, Patricia Moreno; MASSA, Bruno Sergio Ferreira; MONTENEGRO, Nei Botter; GUARNIERO, RobertoObjective: The purpose of our study is to evaluate intraobserver and interobserver reliability of modified Waldenstrom classification system for Legg-Calve-Perthes disease and assess the influence of the professional's area of expertise in the assessment. Methods: Twelve evaluators assessed 40 pairs of pelvic radiographs of patients with Legg-Calve-Perthes disease. After two weeks, a new evaluation was performed by the same evaluators. Kappa and Kendall's W indexes were used to evaluate both intraobserver and interobserver reliability and determine the influence of the evaluators' experience and area of expertise. Results: The average intraobserver kappa value was 0.394, with a reasonable agreement level. The interobserver Kappa value was 0.243 in the first evaluation (95% CI, 0.2270.259 and p < 0.0001) and 0.245 in the second evaluation (95% CI, 0.229-0.260 and p < 0.0001). The Kendall's W values obtained for pediatric orthopedists, radiologists and resident physicians were 0.686, 0.630 and 0.529 ( p < 0.0001), respectively. Conclusion: The modified Waldenstrom classification presented both moderate and reasonable levels of intraobserver agreement, and reasonable level of interobserver agreement. The evaluators' degree of experience and area of expertise influenced the concordance level found.
- The knee in congenital femoral deficiency and its implication in limb lengthening: a systematic review(2021) LEITE, Chilan Bou Ghosson; GRANGEIRO, Patricia Moreno; MUNHOZ, Diego Ubrig; GIGLIO, Pedro Nogueira; CAMANHO, Gilberto Luis; GOBBI, Riccardo GomesCongenital femoral deficiency (CFD) is a rare disorder with several limb anomalies including limb shortening and knee cruciate ligament dysplasia. Limb lengthening is usually performed to correct lower limb discrepancy. However, complications, such as knee subluxation/dislocation, can occur during this treatment. Here, we explore CFD knee abnormalities and knee dislocation during limb elongation, discussing when and whether knee ligament reconstruction prior to the lengthening would be necessary to reduce the risk of knee dislocation. There is not enough support in the literature for the routine reconstruction of cruciate ligaments in CFD patients. Of note, in cases of severe anteroposterior or posterolateral rotatory instability, cruciate ligament reconstruction might be considered to decrease the risk of knee subluxation/dislocation during the lengthening treatment.
- Poor Sleep quality and health-related quality of life impact in adolescents with and without chronic immunosuppressive conditions during COVID-19 quarantine(2021) HELITO, Alberto C.; LINDOSO, Livia; SIECZKOWSKA, Sofia M.; ASTLEY, Camilla; QUEIROZ, Ligia B.; ROSE, Natalia; SANTOS, Claudia Renata P.; BOLZAN, Thalis; PERALTA, Rita Maria I. A.; FRANCO, Ruth R.; COMINATO, Louise; PEREIRA, Rosa Maria R.; TANNURI, Uenis; CAMPOS, Lucia Maria A.; LOURENCO, Benito; TOMA, Ricardo K.; MEDEIROS, Karina; WATANABE, Andreia; GRANGEIRO, Patricia Moreno; FARHAT, Sylvia C.; CASELLA, Caio B.; V, Guilherme Polanczyk; GUALANO, Bruno; SILVA, Clovis A.OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p < 0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.
