RESUMO
Background: Prolotherapy may be a good option in the complementary treatment of knee osteoarthritis (OA) patients, specifically for the increase of functionality. Objective: To determine the effectiveness of prolotherapy in OA grade II - III in the functionality and muscular work of knee flexors and extensors. Material and methods: a double-blind randomized controlled clinical trial was conducted. It included patients diagnosed with OA grades II-III. The experimental group was infiltrated in both knees with 6 ml of 25% glucose solution and 0.05% lidocaine; control group with 0.45% saline solution and 0.05% lidocaine. All patients received a comprehensive rehabilitation program. The isokinetic work of the knee flexor and extensor muscles, pain and functionality were measured, prior to infiltration and at 3-month follow-up. To compare the difference in means, the Student's T test was applied, considering P<0.05 as significant. The project was approved by the local ethics and research committee. Results: 37 patients were recruited, 17 in the prolotherapy group. There were no intergroup differences in functionality, isokinetic knee flexor/extensor work, and pain at baseline, or during follow-up up to 12 weeks. Conclusions: In the present study we identify that both prolotherapy and saline infiltration increased functionality, strength, and decreased pain; however, no statistically significant difference was found between the two group.
Introducción: la proloterapia puede ser buena opción en el tratamiento complementario de pacientes con osteoartrosis de rodilla (OA), específicamente para el incremento de la funcionalidad. Objetivo: determinar la efectividad de la proloterapia en OA grado II-III en la funcionalidad y en el trabajo muscular de flexores y extensores de rodilla. Material y métodos: se realizó un ensayo clínico controlado aleatorizado a doble ciego. Incluyó a pacientes con el diagnostico de OA grados II-III. Al grupo experimental se les infiltraron 6 mL de solución glucosada al 25% y lidocaína al 0.05% en ambas rodillas; al grupo control con solución salina al 0.45% y lidocaína al 0.05%. Todos los pacientes recibieron un programa integral de rehabilitación. Se midió el trabajo isocinético de los músculos flexores y extensores de rodilla, dolor y funcionalidad, previa infiltración y a los tres meses de seguimiento. Para comparar la diferencia de medias, se aplicó la prueba de t de Student, considerando p < 0.05 como significativo. El proyecto se aprobó en el comité local de ética e investigación. Resultados: se reclutaron 37 pacientes, 17 en el grupo de proloterapia. No hubo diferencias intergrupo en la funcionalidad, trabajo isocinético de flexores/extensores de rodilla y dolor iniciales, ni durante el seguimiento hasta las 12 semanas. Conclusiones: en el presente estudio identificó que tanto la proloterapia como la infiltración con solución salina incrementaron la funcionalidad, fuerza y disminuyeron el dolor; sin embargo, no se encontró diferencia estadísticamente significativa entre los dos grupos.

BACKGROUND: Chronic low back pain (LBP) is defined as pain lasting longer than 3 months and is one of the conditions with the most significant social impact. Treatment is complex and includes proliferative agents used in prolotherapy. The mechanism is not known, but osmotic agents (hypertonic solutions of dextrose or glucose) cause cellular rupture and an inflammatory response that releases cytokines and growth factors that lead to scarring and reinnervation. METHODS: Patients with chronic LBP (>12 weeks) who were non-traumatic and unresponsive to at least 1 month of physical therapy were selected. All patients were followed up at a return visit at 1, 3, and 6 months for pain assessment using validated pain questionnaires and scales. RESULTS: Nineteen patients were included in the conservative group and 19 in the glucose group, with the majority being women (57.9%). The patients were between 47 and 59 years of age (39.5%), mixed race (76.33%), married or in a committed relationship (73.7%), and had completed the study for 5.2 years. Overall mean body mass index was 27.3 ± 4.4 kg/m 2 and was higher in the conservative group (28.0 ± 4.7 kg/m 2 ). The groups showed differences in Visual Analog Scale scores, with median and amplitude values close to each other between the time points evaluated and increasing values in the glucose group, which had significantly higher values for this scale at the third evaluation ( P = .031). When comparing the Rolland-Morris scale scores between the groups, there was a significant difference only in the 3-m assessment ( P = .021). In the follow-up assessment, both groups showed significant improvement between T0 and the other assessment time points ( P < .05) in all evaluations. CONCLUSION: Both groups significantly improved on the evaluated scales during follow-up. Overall, no effects were attributable to the glucose components or the prolotherapy protocol.

Este estudo avaliou a influência da fibrina rica em plaquetas injetável (i-PRF) no reparo após procedimento endodôntico regenerativo (REP) em molares imaturos de ratos. Molares superiores direito ou esquerdo de 18 ratos foram divididos em grupos (n = 6): SI foi removido o tecido pulpar do canal mesial, feita irrigação com hipoclorito de sódio e ácido etilenodiaminotetracético, e induzido o sangramento intracanal (SI); iPRF após protocolo de irrigação, foi inserido no interior do canal radicular a i-PRF, sem indução do SI; i-PRF-SI foi realizado o tratamento como no grupo i-PRF, e então, induzido o SI. Ao término, os dentes foram selados. Para produzir a i-PRF, outros 3 animais foram utilizados para a coleta sanguínea intracardíaca, e o sangue foi centrifugado (1200 rpm, 8 min). Aos 21 dias, os animais foram eutanasiados e as peças preparadas para análise histológica e imunohistoquímica para antígeno nuclear de proliferação celular (PCNA) e osteocalcina (OCN). Teste estatístico foi aplicado (p < 0,05). Houve formação de tecido mineralizado em comprimento ou espessura da raiz em todos os grupos (p > 0,05). A formação de tecido conjuntivo nos canais ocorreu até terço médio na maior parte dos espécimes de SI, e até terço cervical em i-PRF e i-PRF-SI (p < 0,05). Houve células semelhantes a odontoblastos no terço apical de metade dos espécimes de i-PRF, e terços apical e médio na maior parte dos espécimes de i-PRF-SI; estas células não foram encontradas no grupo SI (p < 0,05). Os espécimes dos grupos i-PRF e i-PRF-SI tiveram significante número de células positivas para PCNA (p < 0,05) e maior imunomarcação de OCN, principalmente o grupo i-PRF-SI quando comparado ao grupo SI (p < 0,05). Conclui-se que i-PRF auxiliou o processo de reparo após REP em ratos, induzindo formação de tecido conjuntivo nos canais radiculares, presença de células semelhantes a odontoblastos e células positivas para PCNA, e imunomarcação de OCN, principalmente quando associada ao SI.
This study evaluated the influence of injectable platelet-rich fibrin (i-PRF) on repair after regenerative endodontic procedure (REP) in immature molars of rats. Right or left upper molars of 18 rats were divided into groups (n = 6): IB the pulp tissue of the mesial canal was removed, irrigation with sodium hypochlorite and ethylenediaminetetraacetic acid was performed, and intracanal bleeding (IB) was induced; i-PRF after the irrigation protocol, i-PRF was inserted inside the root canal, without inducing of IB; i-PRF-IB the treatment was carried out as in the i-PRF group and then the IB was induced. At the end, the teeth were sealed. To produce the i-PRF, another 3 animals were used for intracardiac blood collection, and the blood was centrifuged (1200 rpm, 8 min). After 21 days, the animals were euthanized and the samples were prepared for histological and immunohistochemical analysis for proliferating cell nuclear antigen (PCNA) and osteocalcin (OCN). Statistical test was applied (P < 0.05). There was formation of mineralized tissue in root length or thickness in all groups (P > 0.05). The formation of connective tissue in the canals occurred up to the medium third in most IB specimens, and up to the cervical third in i-PRF and iPRF-IB (P < 0.05). There were odontoblast-like cells in the apical third of half of the PRF specimens, and apical and medium thirds in most of the i-PRF specimens; these cells were not found in the IB group (P < 0.05). The i-PRF and i-PRF-IB group had significant higher number of PCNA-positive cells (P < 0.05), and higher OCN immunolabeling, mainly i-PRF-IB compared to IB group (P < 0.05). It is concluded that i-PRF helped the repair process after REP in rats, inducing connective tissue formation in root canals, presence of odontoblast-like and PCNA-positive cells, and OCN immunolabeling, mainly when associated with IB.

Este estudo avaliou os efeitos de uma solução experimental de vidro bioativo F18 dopado com cobalto (F18Co) no reparo tecidual após procedimento endodôntico regenerativo (REP, do inglês regenerative endodontic procedure) em molares de ratos. A solução de F18Co foi preparada misturando o pó de F18Co com água destilada na proporção de 1:5. Os primeiros molares superiores direito ou esquerdo de 12 ratos Wistar foram utilizados, nos quais as polpas foram expostas, removidas e os canais irrigados com hipoclorito de sódio (NaOCl) 2,5%, seguido de ácido etilenodiaminotetraacético (EDTA) 17% (5 min cada). Em seguida, os molares foram divididos em dois grupos (n = 6): REP-SS e REP-F18Co, nos quais receberam irrigação final (5 min) com solução salina (SS) ou solução de F18Co, respectivamente. Em seguida, foi induzido sangramento intracanal e o dente foi selado. Molares não tratados foram usados como controles (n = 3). Após 21 dias, os ratos foram eutanasiados e as peças processadas para análise da formação de tecido mineralizado e tecido mole dentro do canal radicular, pela técnica de hematoxilinaeosina. A presença e maturação do colágeno foram avaliadas por coloração de tricrômio de Masson e picrosírius red. Análises da imunomarcação do antígeno nuclear de proliferação celular (PCNA) e osteocalcina (OCN) foram realizadas. Os dados foram submetidos ao teste de Mann-Whitney U (p < 0,05). Houve formação semelhante de tecido mineralizado em espessura e comprimento nos grupos REP-SS e REP-F18Co (p > 0,05). Em relação à presença de tecido neoformado no interior dos canais radiculares, a maioria dos espécimes de REP-F18Co apresentou formação de tecido até o terço cervical do canal radicular, enquanto do grupo REP-SS, até o terço médio (p < 0,05), e houve maior maturação colágena em REP-F18Co (p < 0,05). O número de células positivas para PCNA encontradas no terço apical do canal radicular foi significativamente maior em REP-F18Co, assim como a imunomarcação de OCN, que foi severa na maior parte dos espécimes do grupo REP-F18Co, e leve em REPSS. Conclui-se que a irrigação final com solução de biovidro F18Co em REP não influenciou a formação de tecido mineralizado, mas induziu a formação de tecido conjuntivo no interior dos canais radiculares, com maior maturação colágena, aumento no número de células positivas para PCNA e na imunomarcação de OCN.
This study evaluated the influence of an experimental solution of cobalt-doped F18 bioactive glass (F18Co) on tissue repair following regenerative endodontic procedure (REP) in rat molars. The F18Co solution was prepared at a ratio of 1:5 F18Co powder to distilled water. The right or left upper first molars of 12 Wistar rats were used, where the pulps were exposed, removed, and irrigated with 2.5% sodium hypochlorite (NaOCl), followed by 17% ethylenediaminetetraacetic acid (EDTA) (5 min each). Subsequently, the molars were divided into two groups (n = 6): REP-SS and REP F18Co, where they received a final irrigation (5 min) with saline solution (SS) or F18Co solution, respectively. Then, intracanal bleeding was induced, and the tooth was sealed. Untreated molars were used as controls (n = 3). At 21 days, the rats were euthanized, and the specimens were processed for analysis of mineralized tissue and soft tissue formation inside the root canal using haematoxylin-eosin. The presence and maturation of collagen was evaluated by Masson's trichrome and picrosirius red staining. Immunolabeling analyses of proliferating cell nuclear antigen (PCNA) and osteocalcin (OCN) were performed. The data were submitted to the Mann-Whitney U test (P < 0.05). There was similar formation of mineralized tissue in thickness and length in REP-SS and REP-F18Co groups (P > 0.05). Regarding the presence of newly formed soft tissue, most specimens of the REP-F18Co had tissue formation up to the cervical third of the canal, while the REP-SS specimens showed formation up to the middle third (P < 0.05), and there was higher maturation collagen in REP-F18Co (P < 0.05). The number of PCNA-positive cells found in the apical third of the root canal was significantly higher in the F18Co group, as well as the OCN immunolabeling, which was severe in most specimens of REP-F18Co, and low in most specimens of REP SS. In conclusion, the final irrigation with F18Co bioactive glass solution in REP did not influence mineralized tissue formation but induced soft tissue formation inside the root canals, with higher collagen maturation, and an increase in PCNA-positive cells and OCN immunolabeling

The objective of this study is to compare the effectiveness of dextrose-prolotherapy with other substances for pain relief in patients with primary knee osteoarthritis. The literature screening was done in January 2021 through Medline (PubMed), EMBASE, and Database of the National Institute of Health based on the following criteria: randomized clinical trials that subjected patients with primary knee osteoarthritis who underwent treatment with dextrose-prolotherapy and other substances for pain relief. Paired reviewers independently identified 3381 articles and included 8 trials that met the eligibility criteria. According to the findings of this review, participants that underwent dextrose-prolotherapy showed improvements between baseline and posterior assessments and when compared to saline injections, but when compared to other substances, the results were not clear. Although dextrose-prolotherapy is a useful treatment method by itself, it is still not possible to clearly affirm that it is superior or inferior to its counterparts. There is an urgent need for further studies to bring more evidence to the field.

Background: Despite the fact that slab fracture of the third carpal bone is an event of great worldwide relevance in racehorses, the third carpal fracture doesnt have data on treatments and return to racing in Brazil. The search for efficient treatments and which provide recovery providing horses return to racing is an objective of sports equine medicine. Regenerative therapies like Platelet Rich Plasma (PRP) and Stem Cells (MSc) have demonstrated a great potential in the treatment of several injuries. For the treatment of three Thoroughbred racing horses at Brazilian Jockey Club, with sagittal plane slab fractures of the third carpal bone, we used the association of PRP and Stem Cells for reduction of the rest and good return to conditions athletics of these horses. Cases: Three Thoroughbred racing horses, males, 4 and 5 years old, showed slab fracture third carpal bone in different moments of their activity at Brazilian Jockey Club. Usually, the treatment for this type of fracture is the arthroscopic repair and the conservative management. We performed after initial radiographic evaluation dorsoproximal-dorsodistal oblique (DPr-DDiO) skyline, intra-articular applications of PRP and MSCs. The treatments were performed according to the radiographic follow-up of the lesion evolution. No other treatment was performed concomitantly with cell therapy in the 3 treated patients. Three treatments were performed in the first patient and 2 in the second and third patients. Before each treatment for all patients, we performed radiography dorsoproximal-dorsodistal oblique (DPr-DDiO) skyline of the carpus. After this step, the animal was sedated with 10% xylazine hydrochloride at a dose of 0.5 mg/kg intravenously. Antisepsis of the carpus was performed and applied with radiographic monitoring of the needle positioning, first the PRP in the volume of 2 mL and in sequence, 20 million cells MSCs suspended in autologous...

Objective: Several intraarticular injections, including dextrose and lidocaine, are reported to reduce pain and dysfunction in temporomandibular dysfunction (TMD) and increase maximal jaw opening; our goal was to determine whether dextrose/lidocaine outperforms sterile water/lidocaine for TMD. Design: Pragmatic randomized controlled trial. Setting: Outpatient clinic. Subjects: Chronic (≥3 months) of moderate-to-severe (≥6/10) jaw or facial pain meeting research-specific TMD criteria. Intervention: Blinded intraarticular dextrose prolotherapy (DPT) (20% dextrose/0.2% lidocaine) versus intraarticular lidocaine (0.2% lidocaine in sterile water) at 0, 1, and 2 months. Participants were then unblinded and offered DPT by request for 9 additional months. Main outcome measures: Primary: Numerical Rating Scale (0-10 points) score for facial pain and jaw dysfunction; percentage achieving ≥50% improvement in pain and dysfunction (0, 3, and 12 months). Secondary: Maximal interincisal opening (MIO; 0 and 3 months). Intention-to-treat analysis was by joint using mixed-model regression. Results: Randomization of 29 participants (25 female, 47 ± 17 years, 43 joints) produced similar groups. Three-month pain and dysfunction improvements were similar, but more DPT-treated joints improved by ≥50% in pain (17/22 vs. 6/21; p = 0.028). The MIO improved in both groups (5.6 ± 5.8 mm vs. 5.1 ± 7.0 mm; p = 0.70). From 3 to 12 months, minimal DPT was received by original DPT and lidocaine recipients, 0.5 ± 0.9 and 0.6 ± 1.5 injections, respectively, with only 2 out of 21 joints in the original lidocaine group receiving more than 1 dextrose injection after 3 months. Twelve-month analysis revealed that joints in the original DPT group improved more in jaw pain (4.8 ± 2.4 points vs. 2.6 ± 2.9 points; p = 0.026) and jaw dysfunction (5.3 ± 2.6 points vs. 2.7 ± 2.3 points; p = 0.013). More DPT than lidocaine-treated joints improved by ≥50% in both pain (19/22 vs. 5/21; p = 0.003) and dysfunction (17/22 vs. 7/21; p = 0.040). There were no adverse events; satisfaction was high. Conclusions: Intraarticular DPT resulted in clinically important and statistically significant improvement in pain and dysfunction at 12 months compared to lidocaine injection (ClinicalTrials.gov identifier NCT01617356).

El dolor asociado a heridas complejas se erige como una gran barrera para la resolución de estas, debido a la complejidad de abordaje y a la imposibilidad de establecer un patrón de algoritmo por diversos factores y su carácter heterogéneo, así como por la presencia de manifestaciones múltiples asociadas. Este dolor provoca al paciente un daño no solo físico sino también psicosocial, porque la escasa respuesta a los tratamientos habituales, y si bien es sensible a la medicación con opiáceos, los resultados son insufi cientes a largo plazo en un significativo número de pacientes, en quienes provoca además efectos no deseables. Se establece en el presente trabajo la administración subcutánea de dextrosa 5% a través de una técnica de infiltración perineural para el tratamiento de la infl amación neurogénica responsable del mencionado padecimiento, en las terminaciones libres de los nervios sensitivos cutáneos. Para ello se decidió realizar un estudio descriptivo multicéntrico a partir de junio del 2016 hasta mayo del 2017 en 60 pacientes que presentaban dolor crónico en ulceras de miembro inferior de diferente etiología con antecedente de medicación analgésica previa con resultado parcial (no controlado) y que tuviera evolución de su dolor entre 3 meses y 4 años.
The pain associated with complex wounds is established as a great barrier for the irresolution, due to the complexity of the approach and the impossibility of establishing an algorithm pattern due to various factors and their heterogeneous nature, as well as the presence of associated multiple manifestations. . This pain causes not only physical but psychosocial damage to the patient, because of the poor response to the usual treatments, and although it is sensitive to medication with opiates, the results are insufficient in the long-term in a significant number of patients, in whom it also causes undesirable effects. The present work establishes the subcutaneous administration of 5% dextrose through a perineural infi ltration technique for the treatment of the neurogenic inflammation responsible for the afore mentioned condition, in the free terminations of the cutaneous sensory nerves. For this, it was decided to carry out a multicenter descriptive study from June 2016 to May 2017 in 60 patients who presented chronic pain in lower limb ulcers of different etiology with a history of previous analgesic medication with partial (uncontrolled) outcome and had evolution of your pain between 3 months and 4 years.
