Frecuencia de Signos Óseos de Osteoartritis en la Articulación Temporomandibular en una Población Adulta Chilena Mediante CBCT, Durante 2021-2022

La osteoartritis (OA) de la articulación temporomandibular (ATM) es un desorden degenerativo de etiología multifactorial, que requiere un manejo interdisciplinario. Es considerada como la enfermedad degenerativa más frecuente de la articulación. Por esto es importante conocer lo más preciso posible las estructuras internas del área donde se requiere realizar la intervención o tratamiento, en este caso la ATM. Para esto existen distintos exámenes radiográficos complementarios como: tomografía computarizada, resonancia magnética y por último la tomografía computarizada de haz cónico (CBCT), debido a su capacidad de visualizar tridimensionalmente y con buena definición las estructuras óseas y distintas patologías o alteraciones presentes. A pesar de esto, no hay suficiente evidencia actual que demuestre la frecuencia de signos óseos de osteoartritis presentes en ATM según edad y sexo en la población Chilena. El objetivo este trabajo consistió en Determinar frecuencia de los signos óseos en osteoartritis de ATM mediante CBCT en una población adulta Chilena atendida en un centro radiológico durante los años 2021-2022. Se realizó un estudio observacional descriptivo, donde se observó informes radiológicos de CBCT en pacientes adultos atendidos en el centro radiológico privado de Valdivia durante el periodo del primer semestre del 2021 a primer semestre 2022. Se evaluó la presencia de los siguientes signos óseos imagenológicos: aplanamiento de superficie articular, erosión superficial, osteofitos condilares, esclerosis subcondral, quistes subcortical, esclerosis generalizada, cuerpos libres intraarticulares, reabsorción completa y parcial de la cabeza condilar y trabeculado heterogéneo. De un total de 101 exámenes, 70 exámenes fueron considerados válidos para este estudio según los criterios de selección. Los 31 exámenes restantes no calificaron según los criterios o no presentaban osteoartritis de ATM. De los 70 pacientes 58 pertenecían a mujeres y 12 a hombres. El promedio de edad fue de 37,2 años. Los signos imagenológicos más frecuentes fueron: Trabeculado heterogéneo, Aplanamiento de la superficie articular, Esclerosis subcondral condilar.

Osteoarthritis (OA) of the temporomandibular joint (TMJ) is a degenerative disorder of multifactorial etiology, requiring interdisciplinary management. It is considered the most common degenerative joint disease. For this reason, it is important to know asprecisely as possible the internal structures of the area where the intervention or treatment is required, in this case the TMJ. For this purpose, there are several additional radiographic examinations such as: computed tomography, magnetic resonance imaging and finally cone-beam computed tomography (CBCT), due to its ability to visualize three-dimensionally and with good definition the bone structures and different pathologies or present alterations. Despite this, there is not enough current evidence to demonstrate the frequency of osteoarthritis bone signs present in TMJ according to age and gender in the Chilean population. The aim of this study was to determine the frequency of bone signs of TMJ osteoarthritis through CBCT in a Chilean adult population attended in a radiological center during 2021-2022. A descriptive observational study was made, where CBCT radiological reports were observed in adult patients attended in a private radiological center in Valdivia during the first semester of 2021 to the first semester of 2022. The presence of the following imaging bone signs was evaluated: flattening of the articular surface, surface erosion, condylar osteophytes, subchondral sclerosis, subcortical cysts, generalized sclerosis, intraarticular free bodies, complete and partial reabsorption of the condylar head and heterogeneous trabeculate. Of a total of 101 examinations, 70 examinations were considered valid for this study according to the selection criteria. The remaining 31 examinations did not qualify according to the criteria or did not present TMJ osteoarthritis. Of the 70 patients, 58 were female and 12 were male. The average age was 37.2 years. The most frequent imaging signs were: heterogeneous trabeculation, flattening of the articular surface, subchondral condylar sclerosis.

Alterações osteometabólicas em pacientes em tratamento antineoplásico: revisão de escopo / Osteometabolic changes in patients under antineoplastic treatment: scoping review

Objetivo: sintetizar as principais evidências acerca das alterações osteometabólicas presentes nos pacientes em tratamento antineoplásico. Métodos: trata-se de uma revisão de escopo, seguindo a metodologia do Instituto Joanna Briggs, nas bases de dados PubMed/MedLine, Cochrane Library, LILACS, The British Library e Google Scholar. A revisão está protocolada no Open Science Framework. Resultados: muitos antineoplásicos possuem efeito na arquitetura óssea, reduzindo sua densidade, tais como moduladores seletivos de receptores de estrogênio, inibidores da aromatase, terapia de privação androgênica, e glicocorticoides. Para evitar tais desfechos, o tratamento e prevenção podem ser realizados pela suplementação de cálcio e vitamina D, exercícios físicos, uso de bifosfonatos, denosumab, e moduladores seletivos do receptor de estrogênio. Conclusão: pessoas com maior risco de desenvolver câncer também possuem maior risco de osteopenia e osteoporose, quando processo já estabelecido e em tratamento antineoplásico, devido ao compartilhamento de fatores de risco. Torna-se evidente a necessidade da densitometria óssea nos pacientes em tratamento contra o câncer para de prevenção e promoção de saúde óssea nesses pacientes, além de mais pesquisas com alto nivel de evidência para subsidiar tal uso.

Objective: To summarize the main evidence regarding osteometabolic changes in patients undergoing antineoplastic treatment. Methods: This is a scoping review, following the methodology of the Joanna Briggs Institute, using PubMed/MedLine, Cochrane Library, LILACS, The British Library, and Google Scholar. This review is registered in the Open Science Framework. Results: Many antineoplastics affect bone architecture by reducing its density, such as selective estrogen receptor modulators, aromatase inhibitors, androgen deprivation therapy, and glucocorticoids. To avoid such outcomes, treatment and prevention can be achieved by calcium and vitamin D supplementation, physical exercise, use of bisphosphonates, denosumab, and selective estrogen receptor modulators. Conclusion: people at a higher risk of developing cancer also have a higher risk of osteopenia and osteoporosis when the process is already established and undergoing antineoplastic treatment because of the grouping of risk factors. The need for bone densitometry in patients undergoing cancer treatment to prevent and promote bone health in these patients is evident, in addition to more research with a high level of evidence to support such use.

Expression of CircRNA_0048211 and its correlation with bone metabolic markers in patients with postmenopausal osteoporosis / 中华骨科杂志

Objective:To investigate the diagnostic value of serum CircRNA_0048211 expression level in postmenopausal osteoporosis (PMOP) and its correlation with bone-specific alkaline phosphatase (BALP), osteopontin (OPN), procollagen type I N-terminal propeptide (PINP) and β-crosslaps (β-CTX). Methods:Data of postmenopausal women who underwent physical examination in our hospital from January 2019 to December 2021 were collected. All subjects were measured bone mineral density (BMD) by dual-energy X-ray absorptiometry and divided into PMOP group, decreased bone mass group and normal bone mass group according to BMD level. The serum CircRNA_0048211, BALP, OPN, PINP and β-CTX levels were compared in each group. Binary logistic regression was used to analyze the risk factors of PMOP, the receiver operating characteristic curve (ROC) was drawn to analyze the diagnostic value of CircRNA_0048211, BALP, OPN, PINP and β-CTX on PMOP. The correlation between CircRNA_0048211 expression level and BALP, OPN, PINP and β-CTX was analyzed by Pearson correlation analysis. Results:A total of 218 patients were included in this study. Age is 60.52±6.83 years (range, 47-76 years), body mass index is 24.27±2.28 kg/m 2 (range, 22.18-25.73 kg/m 2) and menopausal time is 10.16±4.25 years (range, 2.30-21.80 years). There were 40 cases in PMOP group, 97 cases in osteopenia group and 81 cases in normal bone mass group. The serum CircRNA_ 0048211, BALP, OPN, PINP and β-CTX was significantly different between PMOP group, osteopenia group and normal group ( F=21.15, P<0.001; F=12.52, P<0.001; F=17.86, P<0.001; F=14.32, P<0.001; F=15.52, P<0.001). The serum CircRNA_0048211 level in PMOP group (0.37±0.08) were significantly lower than that of osteopenia group (1.05±0.46) and normal bone mass group (1.73±0.81), the difference was statistically significant ( P<0.05). The levels of BALP (28.42±7.35 μg/L), OPN (17.28±7.30 ng/ml), PINP (58.40±14.37 ng/ml) and β-CTX (1.52±0.28 μg/L) in PMOP group were significantly higher than those in osteopenia group (22.61±5.93 μg/L, 11.95±5.64 ng/ml, 49.16±11.24 ng/ml, 0.81±0.17 μg/L) and normal bone mass group (16.30±4.18 μg/L, 7.62±3.25 ng/ml, 35.48±7.12 ng/ml, 0.37±0.10 μg/L), the difference was statistically significant ( P<0.05). Binary logistic regression analysis showed that decreased CircRNA_0048211 expression level [ OR=3.53, 95% CI (2.73, 10.32)] was a risk factor for the occurrence of PMOP ( P<0.001). ROC curve showed that CircRNA_0048211≤0.76 has a diagnostic significance on PMOP, and its combination of BALP, OPN, PINP and β-CTX has the highest AUC [0.95, 95% CI (0.89, 1.00)] in diagnosing PMOP. Correlation analysis showed that CircRNA_0048211 expression level were negatively correlated with BALP, OPN, PINP and β-CTX ( r=-0.46, P<0.001; r=-0.80, P<0.001; r=-0.81, P<0.001; r=-0.69, P<0.001). Conclusion:The CircRNA_0048211 showed low expression in PMOP, which was negatively correlated with BALP, OPN, PINP and β-CTX. The combination of these five factors has certain clinical value in the diagnosis of PMOP.

Efficacy of implant surface culture in identification of microorganisms for fracture device-related infection: a preliminary analysis / 中华创伤骨科杂志

Objective:To evaluate the efficacy of implant surface culture in identification of pathogens for fracture device-related infection.Methods:A prospective study was conducted to include the eligible patients who were diagnosed with infection after fracture fixation and needed surgical removal of the implants according to treatment principles at Division of Orthopaedics and Traumatology, Department of Orthopaedics and Traumatology, Nanfang Hospital from November 2020 to January 2023. With informed consent, after rinsing with aseptic normal saline twice, their implants were gently covered with a thin layer of tryptone soy agar medium. Thereafter, the implants were incubated at 37 ℃ with 5% CO 2. Changes on the surface and in the surroundings of the implants were observed every day for consecutive 2 weeks to avoid drying up by supplementing the medium when necessary. Once pathogen colonies formed, samples were collected at 3 independent sites using sterile swabs for laboratory identification. Comparisons were made between the samples from implant surface culture and the intraoperative multisite samples from conventional culture. Results:Included were a total of 75 patients [56 males and 19 females with an age of (46.2±15.4) years]. The most common infection site was the tibia (37 cases), and the most common type of implants was plate and screw (59 cases). The positive rate of implant surface culture was significantly higher than that of conventional culture (86.7% vs. 52.0%, P<0.001). 80.5% (29/36) of the negative patients detected by the conventional culture obtained positive results by the implant surface culture; three of the positive patients detected by the conventional culture obtained negative results by the implant surface culture. The culture results were positive by both culture methods in 36 patients, and consistent by both culture methods in 35 patients, yielding a consistent rate of 97.2% (35/36). The time for implant surface culture was significantly shorter than that for conventional culture [1 (1, 2) d versus 3 (3, 4) d] ( P<0.001). Of the 65 positive patients by the implant surface culture, 59 were detected with monomicrobial infection, with Staphylococcus aureus on the top (29 cases). Conclusion:As the implant surface culture, a novel method, may be superior to the conventional culture in a significantly higher positive rate and a shorter culture time, it may be used as an effective adjunct to the conventional culture in identification of pathogens for fracture device-related infection.

Antibacterial and osteogenic properties of biomimetic mineralized iodine-loaded coating with micro-nano topography on bone implants / 中华创伤骨科杂志

Objective:To investigate the antibacterial and osteogenic properties of biomimetic mineralized iodine-loaded coating with micro-nano topography on the surface of bone implants.Methods:After the fiber network structure of sodium hydrogen titanate was constructed by alkali thermal reaction on the surface of Ti6Al4V (noted as AT), it was biomimetically mineralized in the modified simulated body fluid to form a micro-nano topology with high specific surface area (noted as AT-CaP), and finally loaded with PVPI to construct a novel antibacterial osseointegration coating (noted as AT-CaP-PVPI). The study was conducted in AT, AT-CaP, and AT-CaP-PVPI groups, in each of which 3 parallel experiments were performed. The morphology and colony counting of Staphylococcus aureus on the coating surface were observed to detect the in vitro antibacterial performance of the coating. Fifteen male SD rats were randomly divided into 3 groups ( n=5): AT, AT-CaP, and AT-CaP-PVPI. After intramedullary injection of Staphylococcus aureus into the lower end of the femur in the SD rats, titanium rods coated with AT, AT-CaP, and AT-CaP-PVPI were inserted into the marrow cavity. The osteogenesis, volume ratio of new bone mass and number of trabeculae on the surface of the femoral implants were compared between the 3 groups 4 weeks after operation. Results:In AT and AT-CaP groups, a large number of bacteria grew in their inherent elliptical or spherical shape on the implant surface and a large number of colonies were seen on the plate; in AT-CaP-PVPI group, the bacteria on the coating surface exhibited membrane deformation and depression, some of them were completely broken and dissolved, and a large number died. There was almost no new bone formation around the implants in AT group; new bone scattered around the implants with discontinuous distribution in AT-CaP group; a great amount of new bone was seen around the implants with even distribution but no signs of infection in AT-CaP-PVPI group. The volume ratio of new bone mass and the number of trabeculae on the implant surface in AT-CaP-PVPI group were 0.453±0.206 and 6.055±0.536, respectively, significantly higher than those in AT group (0.046±0.028 and 1.667±1.249) and AT-CaP group (0.188±0.052 and 3.804±0.889) ( P<0.05). Conclusion:Biomimetic mineralized iodine-loaded coating with micro-nano topography on the surface of bone implants shows good antibacterial and osteogenic properties.

A wound diagnosis and treatment mode with integrated medical care for repair of chronic infectious wounds plus bone exposure at lower extremities / 中华创伤骨科杂志

Objective:To evaluate a wound diagnosis and treatment mode with integrated medical care in the repair of chronic infectious wounds plus bone exposure at lower extremities.Methods:A retrospective analysis was conducted of the 64 patients with chronic infectious wound plus bone exposure at the lower 1/3 of the leg who had been admitted to Department of Orthopedics Trauma and Microsurgery, Zhongnan Hospital of Wuhan University from January 2019 to December 2021. The patients were divided into 2 groups according to the wound diagnosis and treatment mode. In the observation group of 31 patients subjected to the wound diagnosis and treatment mode with integrated medical care led by specialist nurses, there were 24 males and 7 females with an age of (53.6±12.4) years, the wound was located at the tibial side in 15 cases and at the fibular side in 16 cases, the wound areas averaged [28.27 (23.56, 37.70) cm 2], and the time from injury to treatment was (27.3±4.1) d. Evaluation of the patient's condition, wound diagnosis and formulation of treatment protocols were performed jointly by a doctor-nurse team after the patients were admitted, and continuous diagnosis and treatment of the wounds were carried out mainly by specialist nurses during the doctors' follow-up. In the control group of 33 patients subjected to the conventional wound diagnosis and treatment mode led by doctors, there were 25 males and 8 females with an age of (51.3±14.3) years, the wound was located at the tibial side in 17 cases and at the fibular side in 16 cases, the wound areas averaged [27.49 (17.84, 40.45) cm 2], and the time from injury to treatment was (27.6±4.0) d. The 2 groups were compared in the wound healing rate, wound recurrence rate, hospitalization time and patients' satisfaction. Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). The observation group achieved a significantly higher wound healing rate within 1 month after treatment [83.87% (26/31)] than the control group [60.61% (20/33)], a significantly lower wound recurrence rate within 6 months after treatment [0% (0/31)] than the control group [18.18% (6/33)], significantly shorter hospitalization time [18.0 (15.1, 20.9) d] than the control group [26.8 (18.4, 40.1) d], and significantly higher patients' satisfaction [50 (50, 50) points] than the control group [50 (42, 50) points] (all P<0.05). Conclusion:In the repair of chronic infectious wounds plus bone exposure at lower extremities, the wound diagnosis and treatment mode with integrated medical care led by specialist nurses may result in a higher wound healing rate, a lower wound recurrence rate, a shorter hospital stay and higher patients' satisfaction than the conventional wound diagnosis and treatment mode led by doctors.

Effect of 3D-printed nano-β-tricalcium phosphate in repairing seawater-soaked tibial defects in rabbits / 中华创伤杂志

Objective:To explore the repairing effects of 3D-printed nano-β-tricalcium phosphate (β-TCP) scaffolds loaded with vancomycin and bone morphogenetic protein-2 (BMP-2) for seawater -soaked tibial bone defects in rabbits. Methods:A total of 27 male New Zealand White rabbits were assigned to the normal group using a random number table method, with each group consisting of 9 rabbits. The rabbit tibial bone defect model was created using the osteotomy surgical method. Eight hours after operation, the wounds in the control group and seawater group were immersed in seawater for 2 hours, and those in the normal group were not immersed. After an observation period of 5-7 days, no significant redness or purulent discharge was observed in the wound appearance, then debridement was performed followed by corresponding implantations: the control group with gelatin sponges loaded with vancomycin and BMP-2, and the other two groups with 3D-printed nano-β-TCP scaffolds loaded with vancomycin and BMP-2. After filling the bone defects with the respective materials, all groups underwent layer-by-layer suturing of the wound, followed by disinfection with iodine and injection of gentamicin to prevent infection. The affected limbs were then immobilized using a plaster cast. The affected limbs were imaged using anteroposterior X-ray at 4, 8 and 16 weeks after operation, and the repair effects were evaluated using the Lane-Sandhu X-ray scoring system. At 16 weeks after operation, the bone defect tissues were collected for HE staining to observe bone tissue growth.Results:At 4 weeks after operation, the Lane-Sandhu X-ray score in the control group was significantly lower than that in the normal group [(2.8±1.1)points vs. (1.1±0.9)points] ( P<0.05), and that in the seawater group [(2.2±1.0)points] was not significantly different from those in the other two groups (all P>0.05). At 8 weeks after operation, the seawater group [(6.1±0.9)points] and the control group [(2.8±1.0)points] exhibited lower Lane-Sandhu X-ray score compared to the normal group [(8.2±1.0)points] (all P<0.05), and the seawater group showed a higher score compared to the control group ( P<0.05). At 16 weeks after operation, the control group [(3.8±1.0)points] exhibited a lower Lane-Sandhu X-ray score compared to the normal group [(10.0±1.3)points] and the seawater group [(9.3±1.2)points] (all P<0.05), while no significant difference was noted between the latter two ( P>0.05). At 16 weeks after operation, histological observations revealed varying degrees of bone tissue formation in three groups, with the normal group showing the best bone defect repair effect, followed by the seawater group. Conclusion:The 3D-printed nano-β-TCP scaffolds loaded with vancomycin and BMP-2 are effective for the treatment of seawater -soaked bone defects, which can promote bone tissue repair.

Current Status of Off-label Use of Denosumab in Bone Tumor and Bone Diseases / 肿瘤防治研究

Denosumab is a monoclonal antibody against the receptor activator of nuclear factor-κB (RANK) ligand (RANKL) that significantly inhibits osteoclast activity and has been approved to treat osteoporosis, giant cell tumor of bone, and prophylactic as well as therapeutic entities for bone metastasis. However, the imbalance of RANKL/RANK/OPG has also been implicated in the pathogenesis of several other rare bone diseases and tumor-like disorders, including aneurysmal bone cyst, fibrous dysplasia of bone, and Langerhans cell histiocytosis. Nevertheless, there have been various clinical reports although these diseases have not been approved for indications. The review aims to summarize the available evidence for the off-label use of denosumab in metabolic bone diseases and tumor-like disorders and provide a reference for clinical diagnosis and treatment.

Introdução: Osteomielite é inflamação aguda ou crônica de ossos trabeculares ou corticais, periósteo, medula óssea e tecidos moles próximos. É classificada pela localização dentro do osso, extensão da dispersão e fonte de infecção. Objetivo: Avaliar os aspectos epidemiológicos dos pacientes internados com osteomielite e analisar relação entre o tempo de internamento e fatores correlatos.Métodos: Estudados dados de 33 pacientes de uma seleção inicial de 42 prontuários. Resultados: O grupo de 0 a 20 anos com 8 (24,4%) pacientes ficou 18 ± 24 dias, 13 (39,4%) adultos jovens (21 a 40 anos): 12,3 ± 12,4 d; 6 (18,1%) adultos (41 a 60 anos) e 6 (18,1%) >60 anos receberam cuidados hospitalares por 31,8 ± 36 e 19,6 ± 15,8 dias respectivamente. O periodo maior de permanência foi de 91 dias. O etilismo (6%), o tabagismo (6%) e o diabetes (6%) foram as comorbidades mais encontradas. A mortalidade foi de 15%, sendo que 60% eram usuários de álcool. O perfil epidemiológico também mostrou o predomínio do sexo masculino na faixa de 21 a 40 anos e o principal agente infeccioso encontrado foi S. aureus. Conclusão: A alta taxa de mortalidade em indivíduos maiores de 50 anos, com maior permanência hospitalar e presença de comorbidades como o etilismo e diabetes mellitus alerta para a necessidade de planejamento estratégico visando intervenções que diminuam prejuízos tanto para o paciente quanto para o sistema de saúde.

Introduction: Osteomyelitis is an acute or chronic inflammation of trabecular or cortical bones, periosteum, bone marrow, and nearby soft tissue. It is classified by location within the bone, extent and source of infection. Objective: Assess the epidemiological aspects of hospitalized patients with osteomyelitis and analyze the relationship between length of stay and correlated factors. Methods: Data were collected from 33 patients from an initial selection of 42. Results: The groups were arranged as follows: 8 (24.4%) individuals from 0-20 yo and with a hospital stay of 18 ± 24 d; 13 (39.4%) young adults (21-40 yo) and 12.3 ± 12.4 d; 6 (18.1%) adults (41-60 yo) and 31.8 ± 36 d; and 6 (18.1%) over 60 yo who were under hospital care for 19.6 ± 15.8 d. The longest period of hospital stay was 91 days. Alcoholism (6%), smoking habits (6%) and diabetes (6%) were the most common comorbidities. Mortality rate was 15%, among which 60% were alcohol users. The epidemiologic profile also showed that the majority of the hospitalized were males between the ages 21-40 yo and the most common infective agent was S. aureus. Conclusion: the high mortality rate in individuals over 50, with comorbidities and longer hospital stays highlights the need for strategic planning yielding interventions that diminish harm to the patients and the health system.

Aggressive Diffuse Intraosseous Hemangioma: Case Report / Hemangioma intraósseo difuso agressivo: Relato de caso

Abstract Vertebral hemangioma is a benign vascular tumor that is usually asymptomatic and is discovered incidentally on imaging. When symptomatic, the most frequent presentation occursinthe formofvague back painofinsidiousonset and,inrare cases, maybeassociated with root or spinal compression, causing sensory and motor deficits. The authors report the case of a 33-year-old man, previously healthy, with a diagnosis of thoracic spine hemangio-ma at multiple levels, in the sternum, in the scapula and in the costal arches; all lesions were symptomatic,and surgicalinterventionwas required; oneof thelesionsatthe thoracicspine level evolved with spinal compression and acute neurological deficit, requiring urgent surgical intervention. Intraosseoushemangiomas represent<1%ofall bonetumors, having few reports of multifocal presentation in the axial and appendicular skeleton. In the literature review, no other case of aggressive multifocal intraosseous hemangioma with this presentation was found, including associated neurological symptoms in the same case.

Resumo O hemangioma vertebral, um tumor vascular benigno, geralmente é assintomático e descoberto incidentalmente em exames de imagem. Quando sintomático, a apresentação mais frequente ocorre sob a forma de dorsalgia vaga de início insidioso e, em raros casos, pode estar associadoa compressão radicularoumedular, causando déficit sensitivo emotor. Osautores relatamocasodeumhomemde33anos, previamentehígido, com diagnósticos de hemangioma na coluna torácica em múltiplos níveis, no esterno, na escápula e nos arcos costais; todas as lesões eram sintomáticas e houve necessidade de intervenção cirúrgica, sendo que uma das lesões ao nível da coluna torácica evoluiu com compressão medular e déficit neurológico agudo, com necessidade de intervenção cirúrgica de urgência. Os hemangiomas intraósseos representam<1% detodosostumores ósseos,eaapresentação multifocal no esqueleto axial e apendicular apresenta poucos relatos. Na revisão bibliográfica, não foi encontrado outro caso dehemangioma intraósseo multifocal agressivo com tal apresentação, inclusive com sintomas neurológicos associados em um mesmo caso.

The Role of Deep Phenotyping of Precision Medicine for Rare Bone Diseases / 罕见病研究

Deep phenotyping is a precise and comprehensive approach used for the precise analysis and comprehensive assessment of multi-system phenotypes of the patients. The approach uses symptoms, signs, various medical examination and laboratory results, and other relevant medical information. In the clinical diagnosis and medical research of rare bone diseases, deep phenotyping plays a pivotal role. The realization of precision medicine primarily comprises three key dimensions: deep phenotyping, stratified medicine, and targeted therapy. The deep phenotyping is the basis for the latter two. Deep phenotyping not only facilitates fine subtyping of diseases, but also allows for the in-depth understanding of genetic data. The use of deep phenotyping requires stand- ardized terminology and specific procedures. Moreover, deep phenotyping shows substantial potential using the application of artificial intelligence technology particularly when combining with multi-omics techniques.

Imaging and clinical study on the relationship between abnormal development of the proximal sacrum and precise insertion of sacroiliac screws / 中华骨科杂志

Objective:To investigate the clinical efficacy of robot-assisted sacroiliac screw implantation in the treatment of proximal dysplasia sacral fractures.Methods:A retrospective analysis was conducted on 191 patients admitted to the Pelvic Department of Tianjin Hospital from May 2016 to January 2021 who underwent robot assisted sacroiliac screw implantation with sacral fractures, including 105 males and 86 females, aged 38.5±6.5 years (ranging from 19 to 69 years old). Among them, there were 85 patients with dysplasia of proximal sacrum. According to the classification of proximal sacral dysplasia, the patients were divided into five groups: the steep sacral alar slope group ( n=60), the mastoid protrusion group ( n=30), the lumbar sacralization group ( n=25), the sacral foramen oval degeneration group ( n=23) and the S 1 anterior cortical depression group ( n=10). The remaining 106 patients were normal group. Iliac cortical density (ICD) line typing was recorded in the 85 patients. The the completion of sacroiliac screw implantation, the Gras score of screw position after operation, the postoperative complications, the minimum diameter of S 1 screw channel (R1), the angle ∠A between the S 1 sacroiliac screw in the coronal plane and the cephalic side, and the angle ∠B between the S 1 sacroiliac screw in the water plane and the ventral side were recorded and compared with those of normal development patients. Results:The incidence of steep sacral alar slope was the highest (31.4%, 60/191). There were 2 or more developmental abnormalities in 24 cases. In 85 cases with dysplasia of proximal sacrum, ICD line type I was found in 8 cases, type II in 12 cases and type III in 65 cases. 49 patients (58.8%, 49/85) were able to complete the implantation of S 1 sacroiliac screw, while 36 patients (35.3%, 36/85) were only able to complete the implantation of S 2 sacroiliac screw. The Gras score of postoperative screw position was 90.05% for grade I, 9.94% for grade II, and 0 for grade III. In 1 case the sacroiliac screw pierced through the anterior cortex of the sacrum, and in 1 case the screw partially threaded into the sacral foramen, and there were no symptoms of iatrogenic nerve injury. The R1 values of the preoperative steep sacral alar slope group, the mastoid protrusion group, the sacral foramen oval degeneration group, the lumbar sacralization group, the sacral foramen oval degeneration group and normal development patient group were 11.4±3.0, 11.6±3.2, 9.8±3.0, 8.8±4.2, 6.5±4.4, and 11.4±3.4 mm, respectively. The differences between the lumbar sacralization group, the sacral foramen oval degeneration group, and the S1 anterior cortical depression group with the normal development patients were statistically significant, respectively ( t=-3.05, P=0.005; t=-2.32, P=0.022; t=-3.45, P=0.006). The postoperative angle ∠A of the above six groups were 33.8°±4.2°, 20.8°±3.5°, 25.8°±2.5°, 35.5°±4.5, 27.8°±3.5° and 26.8°±5.0°, respectively. The postoperative angle ∠B of the above six groups were 27.8°±3.5°, 36.2°±3°, 26.3°±1.8°, 29.8°±2.7°, 14.8°±1.5° and 37.2±4.2°, respectively. The differences between the ∠A of the steep sacral alar slope group, the mastoid protrusion group, and tthe lumbar sacralization group with that of the normal development patients were statistically significant, respectively ( t=9.17, -7.48, 7.97, P<0.001). The differences between the ∠B of the steep sacral alar slope group, the lumbar sacralization group, the sacral foramen oval degeneration group, and the S 1 anterior cortical depression group with that of the normal development patients were statistically significant, respectively ( t=-14.68, -10.93, -19.79, -35.8, P<0.001). Conclusion:This study proposes the "absolute stenosis" of the S 1 screw channel; In the treatment of patients with abnormal proximal sacral fracture, attention should be paid to S 1 anterior cortical depression and lumbar sacralization, and robot-assisted sacroiliac screw implantation can further improve the safety and accuracy of sacroiliac screw implantation.

Abstract Metabolic bone disease of prematurity is a multifactorial pathology that represents a significant cause of morbidity and has increased in prevalence. Its diagnosis requires biochemical, radiological, and, in advanced stages, clinical criteria; therefore, many authors recommend screening and prevention strategies. This article aims to review the most relevant aspects of the metabolic bone disease of prematurity, with emphasis on prevention and early treatment. A bibliographic review was carried out with MeSH terms in the Pubmed, ClinicalKey, ScienceDirect, SciELO, and LILACS databases. Although there is no consensus on screening, diagnosis and treatment guidelines, the main strategy currently used is to provide individualized nutritional support that covers the demands of calcium, phosphorus and vitamin D associated with clinical intervention methods and monitoring of high-risk babies. Understanding this pathology will improve screening strategies and early diagnosis and thus avoid complications.

Abstract Hypovitaminosis D is a prevalent problem in the general population and very common in children; related to different pathologies or factors such as the use of antiepileptic drugs (MAEs), mainly those enzymatic inducers of cytochrome P450, broadly related with bone health. Reason why this study seeks to determine the distribution of vitamin D insufficiency in children with epilepsy in pharmacological treatment and to establish associated factors based on sociodemographic, clinical, and therapeutic characteristics. Methodology: descriptive, cross- sectional, retrospective study with 103 patients with epilepsy in management with MAEs, attending the neuropaediatric consultation in a third-level hospital, information was taken from the medical records of children between 0 and 18 years of age during January 2016 and June 2019. A multivariate model was built in relation to the presence of vitamin D insufficiency and its normal values. Results: 44.7% of patients had vitamin D insufficiency, while 6.8% had deficiency, of which 4 had a history of fractures. A statistically significant association with insufficiency was found in patients residing in rural areas (ORa=4.2 (IC95=1.3-13.4) p=0.013), they belong to a low socio-economic level (Ora=2.9 (95% CI=1.1-77) p=0.030) and suffering from refractory epilepsy (Ora=3.1 (95% CI=1-8.7) p=0.033). Conclusions: hypovitaminosis D is frequent in a patient with epilepsy under pharmacological management with MAE. Insufficiency was associated with refractory epilepsy, low socioeconomic status and coming from rural areas, so routine monitoring of vitamin D levels is recommended in those patients with deficits.

Abstract Objective The present study aimed to evaluate esthetic and functional outcomes from the surgical treatment of Madelung deformity in children. MethodThis is a retrospective study of pediatric patients with Madelung deformity who were surgically treated with dome osteotomy of the distal radius and Vickers ligament section from 2015 to 2018. Patients with a minimum postoperative follow-up period of 12 months were included. Demographic data, surgical technique, clinical and radiographic outcomes were analyzed. Pre and postoperative radiographic evaluation consisted of ulnar tilt, lunate subsidence lunate fossa angle, and palmar carpal displacement measurements. The postoperative clinical evaluation consisted of ranges of motion of the wrist, visual analog scale (VAS) and Disabilities of the Arm, Shoulder and Hand (DASH) score. Results Four patients were included, two with idiopathic Madelung deformity and two with bone dysplasia. All patients were females and presented bilateral disease. Six wrists were operated on. The median age at surgery was 15.5 years old, and the median postoperative follow-up time was of 37.5 months. The postoperative radiographic analysis revealed an average correction of 8.8 ± 7.5° for ulnar tilt, 3.0 ± 3.9 mm for lunate subsidence 8.2 ± 6.6° for lunate fossa angle, and 4.7 ± 2.6 mm for palmar carpal displacement. Average postoperative ranges of motion of the wrist joint were 75.8 ± 3.4° for flexion, 62.5 ± 14.1° for extension, 25.7 ± 2.9° for radial deviation, 40.0 ± 2.9° for ulnar deviation, 88.3 ± 2.4° for pronation, and 82.5 ± 2.5° for supination. The median VAS was 1 for residual pain, 0 for functional deficit, 0 for esthetic impairment, and 10 for recommending the surgical procedure. The median DASH score was 0. Conclusion Madelung deformity treatment using dome osteotomy of the distal radius and Vickers ligament section results in excellent esthetic and functional outcomes.

Drug discovery of sclerostin inhibitors

Sclerostin, a protein secreted from osteocytes, negatively regulates the WNT signaling pathway by binding to the LRP5/6 co-receptors and further inhibits bone formation and promotes bone resorption. Sclerostin contributes to musculoskeletal system-related diseases, making it a promising therapeutic target for the treatment of WNT-related bone diseases. Additionally, emerging evidence indicates that sclerostin contributes to the development of cancers, obesity, and diabetes, suggesting that it may be a promising therapeutic target for these diseases. Notably, cardiovascular diseases are related to the protective role of sclerostin. In this review, we summarize three distinct types of inhibitors targeting sclerostin, monoclonal antibodies, aptamers, and small-molecule inhibitors, from which monoclonal antibodies have been developed. As the first-in-class sclerostin inhibitor approved by the U.S. FDA, the monoclonal antibody romosozumab has demonstrated excellent effectiveness in the treatment of postmenopausal osteoporosis; however, it conferred high cardiovascular risk in clinical trials. Furthermore, romosozumab could only be administered by injection, which may cause compliance issues for patients who prefer oral therapy. Considering these above safety and compliance concerns, we therefore present relevant discussion and offer perspectives on the development of next-generation sclerostin inhibitors by following several ways, such as concomitant medication, artificial intelligence-based strategy, druggable modification, and bispecific inhibitors strategy.
