Tumor-induced osteomalacia: A systematic literature review.

Introduction: Tumor-induced osteomalacia (TIO), is a rare acquired paraneoplastic syndrome characterized by defective bone mineralization, caused by the overproduction of fibroblast growth factor 23 (FGF23) by a tumor. Material and methods: We conducted a systematic review to identify all case reports of TIO, focusing on those associated with mesenchymal tumors. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) consensus, and we included patients with a diagnosis of TIO and histological confirmation of phosphaturic mesenchymal tumors or resolution of the condition after treatment of the tumor. Bibliographical searches were carried out until December 2023 in the Cochrane Library, Medline and Embase, as well as congress abstracts online. Results: We identified 769 articles with 1979 cases reported. Most patients were adults, with a higher incidence on men. Disease duration before diagnosis is a mean of 4.8 years. Most tumors were histologically classified as PMT. Lower limbs were the predominant location. Hypophosphatemia was present in 99.8 % of patients. The FGF23 was elevated at diagnosis in 95.5 %. Resection of the tumor was the treatment of choice in most of patients. After resection, there was a clinical improvement in 97.6 % of cases, and serum phosphorus and FGF23 levels returned to normal ranges in 91.5 % and 81.4 % of the patients, respectively. Conclusion: TIO is usually misdiagnosed with rheumatological or musculoskeletal disorders. The diagnosis should be suspected in patients with hypophosphatemic osteomalacia, and the measurement of serum FGF23 can be useful for diagnosis and management.

Biomedical Applications of the Biopolymer Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV): Drug Encapsulation and Scaffold Fabrication.

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a biodegradable and biocompatible biopolymer that has gained popularity in the field of biomedicine. This review provides an overview of recent advances and potential applications of PHBV, with special emphasis on drug encapsulation and scaffold construction. PHBV has shown to be a versatile platform for drug delivery, offering controlled release, enhanced therapeutic efficacy, and reduced side effects. The encapsulation of various drugs, such as anticancer agents, antibiotics, and anti-inflammatory drugs, in PHBV nanoparticles or microspheres has been extensively investigated, demonstrating enhanced drug stability, prolonged release kinetics, and increased bioavailability. Additionally, PHBV has been used as a scaffold material for tissue engineering applications, such as bone, cartilage, and skin regeneration. The incorporation of PHBV into scaffolds has been shown to improve mechanical properties, biocompatibility, and cellular interactions, making them suitable for tissue engineering constructs. This review highlights the potential of PHBV in drug encapsulation and scaffold fabrication, showing its promising role in advancing biomedical applications.

Healthcare experience among patients with type 2 diabetes: A cross-sectional survey using the IEXPAC tool.

Aim: To assess the experience with health care among patients with type 2 diabetes (T2DM) and to evaluate patients' demographic variables and healthcare-related characteristics which may affect their experience. Methods: A cross-sectional survey was delivered to T2DM adults. Patient experiences were assessed with the 'Instrument for Evaluation of the Experience of Chronic Patients' (IEXPAC) questionnaire, a validated 12-item survey, which describes patient experience within the last 6 months (items 1-11) and hospitalization in the last 3 years (item 12), with possible scores ranging from 0 (worst) to 10 (best experience). Results: A total of 451 T2DM patients responded to the survey (response rate 72.3%; mean age 69.5 ± 10.1 years, 67.8% men). The mean overall IEXPAC score was 5.92 ± 1.80. Mean scores were higher for productive interactions (7.92 ± 2.15) and self-management (7.08 ± 2.27) than for new relational model (1.72 ± 2.01). Only 32.8% of patients who had been hospitalized in the past 3 years reported having received a follow-up call or visit after discharge. Multivariate analyses identified that regular follow-up by the same physician and follow-up by a nurse were associated with a better patient experience. Continuity of healthcare score was higher only in those patients requiring help from others. Conclusions: The areas of T2DM care which may need to be addressed to ensure better patient experience are use of the Internet, new technologies and social resources for patient information and interaction with healthcare professionals, closer follow-up after hospitalization, and a comprehensive multidisciplinary approach with regular follow-up by the same physician and a nurse.

Estudio comparativo de la ecografía Doppler frente a la biopsia de arteria temporal en el diagnóstico de la arteritis de células gigantes / A comparative study of doppler ultrasound against temporal artery biopsy in the diagnosis of giant cell arteritis

INTRODUCCIÓN: La arteritis de células gigantes (ACG) es una vasculitis que afecta a arterias de mediano y gran calibre. La biopsia de la arteria temporal es la técnica diagnóstica de elección. Atendiendo a la demanda asistencial que supone, pretendemos evaluar la utilidad de la ecografía Doppler en los pacientes con sospecha de ACG, su sensibilidad y especificidad como prueba diagnóstica y si puede suplir a la biopsia. MATERIALES Y MÉTODOS: Se ha realizado un estudio prospectivo de 57 pacientes entre febrero de 2015 y julio de 2016, que han sido diagnosticados con exploración mediante ecografía Doppler y biopsia de arteria temporal. RESULTADOS: Fueron incluidos 57 pacientes, de los cuales 3 fallecieron durante el seguimiento y una paciente fue excluida del estudio al negarse a la biopsia. Otros 21 pacientes fueron diagnosticados de ACG por un especialista reumatólogo tras un mínimo de 6 meses de seguimiento. Presentaron ecografía positiva 22 pacientes, de los cuales 8 fueron diagnosticados de ACG y 4 de polimialgia reumática. En nuestro estudio, la sensibilidad de la ecografía es del 42,6% y la especificidad es del 65,7%. Otros 19 pacientes presentaron biopsia positiva: todos ellos fueron diagnosticados de ACG. La biopsia presentó una sensibilidad de un 73,7% y una especificidad de un 100%. CONCLUSIONES: Según nuestro estudio, la utilidad de la ecografía es limitada y son necesarias nuevas investigaciones para determinar su papel en esta entidad

BACKGROUND: Giant cell arteritis (GCA) is a vasculitis that affects medium- and large-sized arteries. Temporal artery biopsy is the gold standard for diagnosis. In view of the high demand for temporal biopsies, the purpose of this study is to evaluate the usefulness of Doppler ultrasonography in patients with suspected giant cell arteritis, to determine its sensitivity and specificity as a diagnostic test and to determine whether it would be possible to substitute biopsy for ultrasonography. MATERIALS AND METHODS: A prospective study was undertaken including 57 patients from February 2015 to July 2016, who have undergone both ultrasonography and temporal biopsy. RESULTS: A total of 57 patients were included, 3of whom died during the follow-up, and a patient was excluded from the study when she refused to have the biopsy. Another 21 patients were diagnosed with GCA by a rheumatologist after a minimum of 6 months of follow-up and 22 patients had positive ultrasonography, 8 of whom were diagnosed with GCA and 4 with polymyalgia rheumatica. In our study, the sensitivity of ultrasonography was 42.6%, and the specificity was 65.7%. A total of 19 patients had a positive biopsy, all of them were diagnosed with GCA. In our study, the sensitivity of the biopsy was 73.7% and the specificity was 100%. CONCLUSIONS: In view of the data from our study, the usefulness of ultrasonography is questionable, and research about the role of ultrasonography in this disease should be further studied

The Use of Antidotes for Calcium Gluconate Extravasation: An Experimental Study in Mice.

BACKGROUND: Calcium gluconate extravasation is a process that can cause serious lesions, such as necrosis and calcification of the soft tissues. The aim of the present study was to analyze the beneficial effects of four possible local antidotes for calcium gluconate extravasation: hyaluronidase, sodium thiosulfate, triamcinolone acetonide, and physiologic saline solution. METHODS: Seventy-four BALB/c mice were used in the study. The substances selected for use in this study were calcium gluconate (4.6 mEq/ml), hyaluronidase (1500 IU/ml), sodium thiosulfate (25%), triamcinolone acetonide (40 mg/ml 0.5 mg/kg), and saline solution 0.9%. Five minutes were allowed to lapse after the calcium gluconate infiltration, and then an antidote was infiltrated. After 3 weeks, a skin biopsy was performed and a radiographic and histologic study was carried out. RESULTS: Only in the group infiltrated with sodium thiosulfate did all skin lesions disappear after the 3-week period after infiltration. In the radiographic study, calcium deposits larger than 0.5 mm were observed in 40 percent of cases without an antidote, in 33 percent with triamcinolone acetonide, in 13 percent with a saline solution, and in none with thiosulfate and hyaluronidase. In the histologic study, calcium deposits were found in 53 percent of cases without antidote, 100 percent of cases with triamcinolone acetonide, 33 percent of cases with saline solution, and 13 percent of cases with sodium thiosulfate or hyaluronidase. CONCLUSION: Sodium thiosulfate and hyaluronidase prevent the development of calcium deposits after calcium gluconate extravasation.

Lesions Associated With Calcium Gluconate Extravasation: Presentation of 5 Clinical Cases and Analysis of Cases Published.

INTRODUCTION: Calcium gluconate extravasation is a process, which, while not common, occurs more frequently in neonatal intensive care units. The aim of this study is to present a number of cases of calcium gluconate extravasation, which have occurred in our hospital, and to carry out a review of those clinical cases published in the literature to obtain relevant epidemiological data. METHODS: Data were gathered on the medical histories of 5 patients who presented lesions secondary to calcium gluconate extravasation in our center. A review of the literature was also performed to include clinical cases of calcium gluconate extravasation already published. RESULTS: Data were collected on 60 cases published in 37 articles. Most patients (55%) were neonates. The average age of these neonates was 8 days. The commonest location of injuries was the back of the hand and wrist (42%). The 2 most frequent symptoms were the appearance of erythema (65%) and swelling/edema (48%) followed by the appearance of skin necrosis (47%), indurated skin (33%), and yellow-white plaques or papules (33%). Most cases are cured within a period of 3 to 6 months. Fifty percent of patients required surgery, and in 13% of cases, skin grafts were performed. The most frequent histological finding was the presence of calcium deposits. Other histological findings described were the presence of necrosis, lymphohistiocytic infíltrate, and granulomas. Most histological findings were located in the dermis. Most x-rays showing calcium deposits had been performed at 3 to 4 weeks. CONCLUSIONS: Calcium gluconate extravasation is a process, which, although infrequent, is associated with serious skin and soft-tissue lesions, mainly affecting infants. Further studies are needed to determine possible specific procedures to be carried out in these cases.

A survey of anatomical items relevant to the practice of rheumatology: pelvis, lower extremity, and gait.

This study aimed to generate a minimum list of structural and functional anatomical items about the pelvis/hip, knee, ankle/foot, gait, and lower limb innervation, which are most relevant to the practice of rheumatology. To determine their perceived relevance to clinical practice, seven members of the Mexican Clinical Anatomy Task Force compiled an initial list of 470 anatomical items. Ten local and international experts according to a 0-10 Likert scale ranked these items. Of the original list, 101 (21.48%) items were considered relevant (global rate >40). These included 36/137 (26.27%) pelvis and hip items, 25/82 (30.48%) knee items, 22/168 (13.98%) ankle/foot items, 11/68 (16.17%) neurologic items, and 7/15 (46.66%) gait-related items. We propose that these 101 anatomical items of the lower extremity, when added to the 115 anatomic items of the upper extremity and spine we previously reported, may represent an approximation to the minimal anatomical knowledge central to the competent practice of rheumatology. The meager representation of ankle and foot items may reflect a lesser emphasis in these anatomical regions during rheumatologic training. Attention to these and related items during rheumatologic training and beyond may sharpen the rheumatologist's ability in the differential diagnosis of regional pain syndromes as well as strengthen an endangered art: the rheumatologic physical examination.

Ovine Mesenchymal Stromal Cells: Morphologic, Phenotypic and Functional Characterization for Osteochondral Tissue Engineering.

INTRODUCTION: Knowledge of ovine mesenchymal stromal cells (oMSCs) is currently expanding. Tissue engineering combining scaffolding with oMSCs provides promising therapies for the treatment of osteochondral diseases. PURPOSE: The aim was to isolate and characterize oMSCs from bone marrow aspirates (oBMSCs) and to assess their usefulness for osteochondral repair using ß-tricalcium phosphate (bTCP) and type I collagen (Col I) scaffolds. METHODS: Cells isolated from ovine bone marrow were characterized morphologically, phenotypically, and functionally. oBMSCs were cultured with osteogenic medium on bTCP and Col I scaffolds. The resulting constructs were evaluated by histology, immunohistochemistry and electron microscopy studies. Furthermore, oBMSCs were cultured on Col I scaffolds to develop an in vitro cartilage repair model that was assessed using a modified International Cartilage Research Society (ICRS) II scale. RESULTS: oBMSCs presented morphology, surface marker pattern and multipotent capacities similar to those of human BMSCs. oBMSCs seeded on Col I gave rise to osteogenic neotissue. Assessment by the modified ICRS II scale revealed that fibrocartilage/hyaline cartilage was obtained in the in vitro repair model. CONCLUSIONS: The isolated ovine cells were demonstrated to be oBMSCs. oBMSCs cultured on Col I sponges successfully synthesized osteochondral tissue. The data suggest that oBMSCs have potential for use in preclinical models prior to human clinical studies.

A survey of anatomical items relevant to the practice of rheumatology: upper extremity, head, neck, spine, and general concepts.

This study aimed to identify the anatomical items of the upper extremity and spine that are potentially relevant to the practice of rheumatology. Ten rheumatologists interested in clinical anatomy who published, taught, and/or participated as active members of Clinical Anatomy Interest groups (six seniors, four juniors), participated in a one-round relevance Delphi exercise. An initial, 560-item list that included 45 (8.0 %) general concepts items; 138 (24.8 %) hand items; 100 (17.8 %) forearm and elbow items; 147 (26.2 %) shoulder items; and 130 (23.2 %) head, neck, and spine items was compiled by 5 of the participants. Each item was graded for importance with a Likert scale from 1 (not important) to 5 (very important). Thus, scores could range from 10 (1 × 10) to 50 (5 × 10). An item score of ≥40 was considered most relevant to competent practice as a rheumatologist. Mean item Likert scores ranged from 2.2 ± 0.5 to 4.6 ± 0.7. A total of 115 (20.5 %) of the 560 initial items reached relevance. Broken down by categories, this final relevant item list was composed by 7 (6.1 %) general concepts items; 32 (27.8 %) hand items; 20 (17.4 %) forearm and elbow items; 33 (28.7 %) shoulder items; and 23 (17.6 %) head, neck, and spine items. In this Delphi exercise, a group of practicing academic rheumatologists with an interest in clinical anatomy compiled a list of anatomical items that were deemed important to the practice of rheumatology. We suggest these items be considered curricular priorities when training rheumatology fellows in clinical anatomy skills and in programs of continuing rheumatology education.

Spanish Rheumatology Society and Hospital Pharmacy Society Consensus on recommendations for biologics optimization in patients with rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis.

OBJECTIVE: The aim of this study was to establish guidelines for the optimization of biologic therapies for health professionals involved in the management of patients with RA, AS and PsA. METHODS: Recommendations were established via consensus by a panel of experts in rheumatology and hospital pharmacy, based on analysis of available scientific evidence obtained from four systematic reviews and on the clinical experience of panellists. The Delphi method was used to evaluate these recommendations, both between panellists and among a wider group of rheumatologists. RESULTS: Previous concepts concerning better management of RA, AS and PsA were reviewed and, more specifically, guidelines for the optimization of biologic therapies used to treat these diseases were formulated. Recommendations were made with the aim of establishing a plan for when and how to taper biologic treatment in patients with these diseases. CONCLUSION: The recommendations established herein aim not only to provide advice on how to improve the risk:benefit ratio and efficiency of such treatments, but also to reduce variability in daily clinical practice in the use of biologic therapies for rheumatic diseases.

Tratamiento de lesiones del cartílago articular con terapia celular / Treatment of joint cartilage lesions with cell therapy

Las lesiones del cartílago articular que no afectan a la integridad del hueso subcondral no se reparan espontáneamente. El carácter asintomático de estas lesiones propicia la progresiva degeneración articular y el desarrollo de un proceso artrósico. Para evitar la necesidad de reemplazo protésico, se han desarrollado distintos tratamientos celulares con el objetivo de fomar un tejido de reparación con estructura, composición bioquímica y comportamiento funcional iguales que los del cartílago articular natural. Las técnicas basadas en facilitar el acceso al sistema vascular generan un tejido de reparación fibrocartilaginoso que no reúne las condiciones del cartílago articular. El implante de condrocitos autólogos y la mosaicoplastia autóloga aportan un tejido de reparación de mayor calidad, pero ambas técnicas implican la escisión de cartílago sano, bien para obtener una elevada cantidad de condrocitos, bien para extraer cilindros osteocondrales que se implantan en el defecto. Las células madre mesenquimales constituyen una prometedora herramienta de reparación del cartílago articular en fase de experimentación. Aunque las estrategias actuales de terapia celular producen mejorías clínicas y funcionales, todavía no es posible generar un tejido de reparación resistente a la degeneración y con características de cartílago articular normal (AU)

Articular cartilage lesions which do not affect the integrity of subchondral bone, they are not able to repair it expontaneously. The asymptomatic nature of these lesions induces articular cartilage degeneration and development of an arthrosic process. To avoid the necessity to receive joint replacement surgery, it has been developed different treatments of cellular therapy which are focused to create new tissues whose structure, biochemistry composition and function will be the same than native articular cartilage. Approaches used to access the stream produce a fibrocartilaginose tissue which is not an articular cartilage. Implantation of autologous chondrocytes and autologous mosaicplasties induces a quality better articular cartilage. Furthermore both techniques involve damage in the sane cartilage; because of trying to get a big amount of chondrocytes or because of extraction osteochondral cylinder which will be implanted in the injured joint. The stem cells are a promising toll to repair articular cartilage, however they are in a previous experimentation step yet. Although the present studies using cellular therapy improves clinically and functionally, it is not able to regenerate an articular cartilage which offer resistance the degeneration process (AU)

[Treatment of joint cartilage lesions with cell therapy]. / Tratamiento de lesiones del cartílago articular con terapia celular.

Articular cartilage lesions which do not affect the integrity of subchondral bone, they are not able to repair it expontaneously. The asymptomatic nature of these lesions induces articular cartilage degeneration and development of an arthrosic process. To avoid the necessity to receive joint replacement surgery, it has been developed different treatments of cellular therapy which are focused to create new tissues whose structure, biochemistry composition and function will be the same than native articular cartilage. Approaches used to access the stream produce a fibrocartilaginose tissue which is not an articular cartilage. Implantation of autologous chondrocytes and autologous mosaicplasties induces a quality better articular cartilage. Furthermore both techniques involve damage in the sane cartilage; because of trying to get a big amount of chondrocytes or because of extraction osteochondral cylinder which will be implanted in the injured joint. The stem cells are a promising toll to repair articular cartilage, however they are in a previous experimentation step yet. Although the present studies using cellular therapy improves clinically and functionally, it is not able to regenerate an articular cartilage which offer resistance the degeneration process.
