Optical frequency domain imaging-guided versus intravascular ultrasound-guided percutaneous coronary intervention for acute coronary syndromes: the OPINION ACS randomised trial.

BACKGROUND: The clinical benefits of optical frequency domain imaging (OFDI)-guided percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) remain unclear. AIMS: We sought to compare intravascular ultrasound (IVUS)- and OFDI-guided PCI in patients with ACS. METHODS: OPINION ACS is a multicentre, prospective, randomised, non-inferiority trial that compared OFDI-guided PCI with IVUS-guided PCI using current-generation drug-eluting stents in ACS patients (n=158). The primary endpoint was in-stent minimum lumen area (MLA), assessed using 8-month follow-up OFDI. RESULTS: Patients presented with ST-segment elevation myocardial infarction (55%), non-ST-segment elevation myocardial infarction (29%), or unstable angina pectoris (16%). PCI procedural success was achieved in all patients, with comparably low periprocedural complications rates in both groups. Immediately after PCI, the minimum stent area (p=0.096) tended to be smaller for OFDI versus IVUS guidance. Proximal stent edge dissection (p=0.012) and irregular protrusion (p=0.03) were significantly less frequent in OFDI-guided procedures than in IVUS-guided procedures. Post-PCI coronary flow, assessed using corrected Thrombolysis in Myocardial Infarction frame counts, was significantly better in the OFDI-guided group than in the IVUS-guided group (p<0.001). The least squares mean (95% confidence interval [CI]) in-stent MLA at 8 months was 4.91 (95% CI: 4.53-5.30) mm2 and 4.76 (95% CI: 4.35-5.17) mm2 in the OFDI- and IVUS-guided groups, respectively, demonstrating the non-inferiority of OFDI guidance (pnon-inferiority<0.001). The average neointima area tended to be smaller in the OFDI-guided group. The frequency of major adverse cardiac events was similar. CONCLUSIONS: Among ACS patients, OFDI-guided PCI and IVUS-guided PCI were equally safe and feasible, with comparable in-stent MLA at 8 months. OFDI guidance may be a potential option in ACS patients. This study was registered in the Japan Registry of Clinical Trials (jrct.niph.go.jp: jRCTs052190093).

Investigating the efficacy of Endolift laser and Nanofat as a combination therapy for horizontal neck lines compared to Nanofat autologous alone.

BACKGROUND: The emergence of horizontal neck wrinkles is increasingly becoming a focal point for both cosmetic professionals and clients. Various treatment approaches must be considered to address this issue effectively, owing to its diverse underlying causes. The study explores the potential of utilizing the Endolift laser in conjunction with nanofat injection as a viable treatment option. METHODS: Twenty patients with horizontal neck wrinkles involved in the study. Ten patients underwent treatment with a combination of Endolift laser and nanofat injection and 10 patients treated with nanofat injection alone. The participants were monitored for 6 months post-treatment. Biometric measurements were utilized to assess outcomes, including changes in volume, depth, and area of the wrinkles, skin elasticity, as well as the diameter and density of the epidermis and dermis in the treated area. Skin improvement was evaluated by two independent dermatologists, who compared before and after photos in a blinded manner. Patient satisfaction levels were also documented. RESULTS: The Visioface analysis showed a notable decrease in neck wrinkle depth and area in both groups. However, the group receiving the combination treatment of Endolift laser and nanofat exhibited a significantly greater improvement compared to the group treated with nanofat alone. Skin ultrasonography results demonstrated an increase in thickness and density of the dermis and epidermis in both groups. Particularly, the group treated with Endolift laser-nanofat displayed significant enhancements in dermis and epidermis density and thickness when contrasted with the nanofat-only group. Analysis with Cutometer revealed a marked enhancement in skin elasticity in the Endolift-nanofat treated group in comparison to the nanofat-only treated group. Furthermore, in the Endolift-nanofat treated group, a substantial majority (90%) of patients exhibited improvement. Patient evaluations highlighted significant distinctions between the two groups, with 95% of patients in the Endolift-nanofat treated group demonstrating enhancement. CONCLUSION: Both methods notably enhance horizontal neck wrinkles; nevertheless, the combination of endolift laser and nanofat seems to be more efficient for treating horizontal neck wrinkles.

Targeted precision cryotherapy for acne vulgaris.

BACKGROUND: Acne vulgaris poses a significant dermatological challenge, necessitating alternative treatments due to limitations and side effects associated with current therapies. This pilot clinical trial investigated the feasibility and efficacy of precision cryotherapy for acne vulgaris. METHODS: A total of 20 volunteers underwent targeted precision cryotherapy using a carbon dioxide-based device. Treatment outcomes were assessed using various parameters, including Investigator Global Assessment (IGA) score, acne lesion count, erythema index (EI), global evaluation score, and participant satisfaction. Safety monitoring included adverse event reporting and physical examination. RESULTS: Precision cryotherapy demonstrated a significant reduction (90.25%) in the acne lesion count by week 4, with clinical improvement indicated by IGA score reduction (p < 0.001). The EI showed notable improvements at weeks 1, 2, and 4. The global evaluation score demonstrated a 75%-100% clinical improvement at Visit 4. Participants reported high satisfaction (6.75 ± 0.79) with the procedure. No adverse event or discomfort was reported. CONCLUSION: Precision cryotherapy effectively improved acne lesions, which was safe and satisfactory for participants. These findings suggest its potential as an alternative therapeutic modality, especially for populations with limited treatment options. Further research is needed to validate the results and explore underlying mechanisms.

A prognostic model for thermal ablation of benign thyroid nodules based on interpretable machine learning.

Introduction: The detection rate of benign thyroid nodules is increasing every year, with some affected patients experiencing symptoms. Ultrasound-guided thermal ablation can reduce the volume of nodules to alleviate symptoms. As the degree and speed of lesion absorption vary greatly between individuals, an effective model to predict curative effect after ablation is lacking. This study aims to predict the efficacy of ultrasound-guided thermal ablation for benign thyroid nodules using machine learning and explain the characteristics affecting the nodule volume reduction ratio (VRR). Design: Prospective study. Patients: The clinical and ultrasonic characteristics of patients who underwent ultrasound-guided thermal ablation of benign thyroid nodules at our hospital between January 2020 and January 2023 were recorded. Measurements: Six machine learning models (logistic regression, support vector machine, decision tree, random forest, eXtreme Gradient Boosting [XGBoost], and Light Gradient Boosting Machine [LGBM]) were constructed to predict efficacy; the effectiveness of each model was evaluated, and the optimal model selected. SHapley Additive exPlanations (SHAP) was used to visualize the decision process of the optimal model and analyze the characteristics affecting the VRR. Results: In total, 518 benign thyroid nodules were included: 356 in the satisfactory group (VRR ≥70% 1 year after operation) and 162 in the unsatisfactory group. The optimal XGBoost model predicted satisfactory efficacy with 78.9% accuracy, 88.8% precision, 79.8% recall rate, an F1 value of 0.84 F1, and an area under the curve of 0.86. The top five characteristics that affected VRRs were the proportion of solid components < 20%, initial nodule volume, blood flow score, peripheral blood flow pattern, and proportion of solid components 50-80%. Conclusions: The models, based on interpretable machine learning, predicted the VRR after thermal ablation for benign thyroid nodules, which provided a reference for preoperative treatment decisions.

Effect of alemtuzumab over sNfL and sGFAP levels in multiple sclerosis.

Introduction: Alemtuzumab is a highly effective pulsed immune reconstitution therapy for multiple sclerosis (MS). Aim: To evaluate serum neurofilament light chain (sNfL) and serum glial fibrillary acidic protein (sGFAP) in patients with relapsing-remitting MS who have been treated with Alemtuzumab over the course of 2 years. Methods: This prospective study involved MS patients treated with Alemtuzumab at a referral MS center. Both sNfL and sGFAP were analyzed at baseline and then again at 6, 12, and 24 months post-treatment using the single molecule array (SiMoA) technique. We also recruited matched healthy controls (HCs) for comparison. Results: The study included 46 patients (with a median age of 34.2 [Interquartile range (IQR), 28.7-42.3] years, 27 of which were women [58%]) and 76 HCs. No differences in demographic characteristics were observed between patients and HC. The median disease duration was 6.22 (IQR, 1.56-10.13) years. The median annualized relapse rate before treatment was 2 (IQR, 1-3). At baseline, sNfL and sGFAP levels were higher in MS patients (median of 18.8 [IQR, 10.7-52.7] pg/ml and 158.9 [IQR, 126.9-255.5] pg/ml, respectively) when compared to HC (6.11 [IQR, 2.03-8.54] pg/ml and 91.0 [72.6-109] pg/ml, respectively) (p<0.001 for both comparisons). The data indicates that 80% of patients had high (≥10 pg/ml) sNfL values at baseline. We observed a significant decrease in sNfL levels at 6 (65%, p = 0.02), 12 (70.8%, p<0.001), and 24 (78.1%, p<0.001) months. sNfL reached similar levels to HC only after 24 months of Alemtuzumab treatment. During the follow-up period, no changes were identified in the sGFAP values. Conclusion: Alemtuzumab leads to the normalization of sNfL values in MS patients after 2 years of treatment, with no apparent effect on sGFAP values.

Hope for all? Investigating the moderating effect of social inhibition on the association between hope and outcome in an integrative group therapy program.

Existing research supports the therapeutic value of hope in different therapies and for diverse patient groups. Patients who are socially inhibited tend to have a particularly difficult time in group therapy, and the experience of hope in that context may be especially poignant for them. The present study investigated the impact of hope on the outcome of a group-based treatment and whether this impact differed for patients depending on their level of social inhibition. The sample consisted of 49 consecutively admitted patients who completed treatment in an intensive, integrative group therapy program. Patients completed four self-report measures to assess hope, social inhibition, quality of life, and depression. Regression with moderation analysis was employed. The analyses revealed that social inhibition significantly moderated the impact of hope on treatment outcome, indicating that hope had a more pronounced effect among those patients with relatively higher levels of social inhibition.

Endoscopic Combined Intrarenal Surgery: best practices and future perspectives.

INTRODUCTION: Endoscopic Combined Intrarenal Surgery (ECIRS) has emerged as a promising technique for the management of large and complex kidney stones, potentially offering advantages over traditional Percutaneous Nephrolithotomy (PCNL). This study aims to evaluate best practices, outcomes, and future perspectives associated with ECIRS. MATERIALS AND METHODS: A comprehensive PubMed search was conducted from 2008 to 2024, using MESH terms and the following key words: "ECIRS" and "Endoscopic Combined Intrarenal Surgery" The search yielded 157 articles, including retrospective cohort studies, two randomized controlled trials (RCTs), and four meta-analyses comparing ECIRS with PCNL. Most important findings were summarized regarding indications, patient positioning, kidney access, tract size, surgical outcomes, and complications. RESULTS: ECIRS demonstrated higher stone-free rate, lower complication rate, and a reduced need for multiple procedures compared to traditional PCNL. Additionally, ECIRS has the potential to integrate new technologies to further enhance outcomes. CONCLUSION: ECIRS demonstrates significant advantages in the management of large kidney stones. Future research should focus on well-designed RCTs to provide robust evidence of its efficacy, safety, and cost-effectiveness, potentially establishing ECIRS as the first option treatment for complex kidney stones.

Are very thin patients at a higher risk of complications when submitted to percutane-ous nephrolithotomy?

PURPOSE: To assess the impact of thinness on the outcome of the percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: A matched case-control study was performed using a prospectively collected database of all patients who underwent PCNL between June 2011 and October 2021. The patients were stratified into two groups according to their phenotypic characteristics, arbitrarily defined according to their body mass index (BMI): <0kg/m2 (Group 1, very thin patients, G<20) and ≥25 kg/m2 (Group 2, non-thin patients, G≥25). Patients were randomly matched based on Guy's Stone Score (GSS) according to case complexity at a ratio of 1:3. RESULTS: A total of 204 patients were enrolled in this study: 51 patients (G<20) and 153 controls (G≥25). Complications occurred in 15.2% of the patients, with 5.4% of these complications classified as major complications (Clavien grade ≥ 3). According to complications there were no significant differences between the groups. The overall complication rates were 17.6% in the G<20 and 14.4% in the G≥25 (p = 0.653). The major complication rates were 3.9% in the G<20 and 5.8% in the G≥25 (p=0.429). No differences in transfusion or urinary fistula rates were found. CONCLUSIONS: In this study, very thin patients were not at a higher risk of complications when submitted to PCNL than in those with a BMI of ≥25 kg/m2. Apparently, this technique can be used in these patients, just as it is used in any other type of patient, independently of their BMI.

Totally Intracorporeal Robot-Assisted Bilateral Ileal Ureter Replacement for the Treat-ment of Ureteral Strictures using Kangduo Surgical Robot 2000 Plus.

PURPOSE: Ureteroplasty using buccal or lingual mucosa graft Is feasible for complex proximal ureteral stricture (1, 2). Ileal ureter replacement is considered as the last resort for ureteral reconstruction. Totally intracorporeal robot-assisted ileal ureter replacement can be performed safely and effectively (3). In China, the KangDuo Surgical Robot 2000 Plus (KD-SR-2000 Plus) has been developed featuring two surgeon consoles and five robotic arms. This study aims to share our experience with totally intracorporeal robot-assisted bilateral ileal ureter replacement using KD-SR-2000 Plus. MATERIALS AND METHODS: A 59-year-old female patient underwent a complete intracorporeal robot-assisted bilateral ileal ureter replacement for the treatment of ureteral strictures using KD-SR-2000 Plus. The surgical procedure involved dissecting the proximal ends of the bilateral ureteral strictures, harvesting the ileal ureter, restoring intestinal continuity, and performing an anastomosis between the ileum and the ureteral end as well as the bladder. The data were prospectively collected and analyzed. RESULTS: The surgery was successfully completed with single docking without open conversion. The length of the harvested ileal ureter was 25 cm. The docking time, operation time and console time were 3.4 min., 271 min and 231 min respectively. The estimated blood loss was 50 mL. The postoperative hospitalization was 6 days. No perioperative complications occurred. CONCLUSIONS: It is technically feasible to perform totally intracorporeal robot-assisted bilateral ileal ureter replacement for the treatment of ureteral strictures using KD-SR-2000 Plus. A longer follow-up and a larger sample size are required to evaluate its safety and effectiveness.

First impressions of Telesurgery robotic-assisted radical prostatectomy using the Edge medical robotic platform.

PURPOSE: We reported, as a referral center in prostate cancer, our perspectives and experience performing Telesurgery using robotic surgery and 5G network. MATERIAL AND METHODS: We described and illustrated the Telesurgery applications and outcomes to treat a patient with prostate cancer located 1300 kilometers away from the surgeon (Beijing-Harbin) in China. We used the Edge Medical Robot (MP1000) in November 2023 in a 71-year-old patient with Gleason 6 (ISUP 1) in 8 cores from 13, PSA of 14 ng/dL, and clinical stage cT2a. MRI described a PIRADS 5 nodule on the left peripheral zone at the base, and 20gr prostate. We described details about the connection between centers, perioperative outcomes, and our perspectives as a referral center in prostate cancer. RESULTS: We had no delays, or problems with network connection between the centers. The procedure was performed in 60 minutes, with no intra- or postoperative complications. Estimated blood loss was 100 mL. The patient was ambulating soon after anesthesia recovery. Final pathology described a Gleason 6 (ISUP 1) involving the left base and left seminal vesicle, negative surgical margins, and no lymph node involvement (pT3bN0). The patient was continent soon after catheter removal (7 days). CONCLUSION: As technological progress introduced novel robotic platforms and high-speed networks, the concept of Telesurgery became a tangible reality while 5G technology solved latency and transmission concerns. However, with these advancements, ethical considerations and regulatory frameworks should underline the importance of transparency and patient safety with responsible innovation in the field.

Exploring the safety and efficacy of robotic neurosurgery in the management of intracerebral hemorrhage: a systematic review and meta-analysis.

Intracerebral hemorrhage (ICH) carries a high mortality rate of around 50% annually, with management traditionally involving medical and surgical approaches. This systematic review and meta-analysis compare robotic neurosurgery with conventional treatments for ICH. We adhered to PRISMA guidelines, analyzing data from MEDLINE, EMBASE, and Cochrane CENTRAL up to October 2023, including randomized controlled trials, non-randomized controlled trials, and cohort studies. We evaluated outcomes such as operation time, drainage time, intraoperative blood loss, hospitalization, mortality, and complications. Of the 10 studies with 1187 participants (609 in robotic neurosurgery and 578 in conventional management), robotic neurosurgery was associated with significantly reduced operation times, drainage times, and hospitalization needs, though intraoperative blood loss and mortality rates showed no significant difference. Robotic neurosurgery also demonstrated a lower risk of rebleeding but similar safety profiles for other complications. Despite these advantages, significant heterogeneity and limited RCTs highlight the need for further research. Robotic neurosurgery appears beneficial in improving ICH management outcomes, warranting additional multicenter trials to confirm long-term efficacy and safety.

Satisfaction and results of the subareolar incision as treatment for gynecomastia in adolescents: experience of two centers.

Gynecomastia is a benign glandular proliferation that can affect adolescents causing significant psychological discomfort. Generally, it is idiopathic but underlying endocrinological conditions must be excluded. Different surgical techniques are available, the surgical correction with subareolar incision achieves the goal of satisfactory aesthetic result for patients. We studied all patients treated for gynecomastia in two centers of pediatric surgery. After collection of a detailed family history, we evaluated the presence of early onset of puberty, congenital abnormalities of the external genitalia, use of drugs, eating habits and the presence of genetic disorders. Laboratory tests and ultrasound were made to exclude endocrinological disorders. The surgical treatment was performed by a subareolar incision with gland and adipose tissue excision. A Body - Q chest module to evaluate patient satisfaction has been proposed to everyone before and after surgery. 47 adolescents with median age of 15 years were surgically treated. Three presented endocrinological disorders. Grade of gynecomastia for surgery was: III in 40 patients and IIb in 7 patients. Postoperative complications occurred in 5 patients. The Body - Q chest module was completed by 42 patients and showed good results for all points analyzed, except for social feelings. Gynecomastia in adolescents can be surgically treated with subareolar incision, reporting good aesthetic results and low incidence of complications. Specific tests are useful to assess patient satisfaction.

[Total knee replacement in patients under 60 years with high functional demand: functional outcomes and return to sports after an average 2-year follow-up]. / Reemplazo total de rodilla en pacientes menores de 60 años con demanda funcional elevada: resultados funcionales y retorno al deporte después de un promedio de dos años de seguimiento.

INTRODUCTION: a common concern in presurgical medical appointment of total knee replacement medical appointment is return to exercise. The purpose of this study was to analyze functional results and return to sport in patients under 60 years of age after this surgery. MATERIAL AND METHODS: we retrospectively analyzed 41 total knee replacements in 36 athletic patients (average age: 53 years [46-60]). Average follow-up of two years (6 months-5 years). Diagnoses: 37 osteoarthritis, three sequelae of Rheumatoid Arthritis, 1 extra-articular deformity. Functional and radiographic outcomes assessed using modified Knee Society and High Activity Arthroplasty Scores. RESULTS: average improvement from 31.95 to 91.61 in KSS and average from 7.95 to 13.73 in HAAS. Return to sport in 3.5 months average (range 2-6 months). Three patients did not return to sport. CONCLUSIONS: we consider that delaying surgery in these patients will cause progression in their osteoarthritis pathology and cessation of their sports activities. This makes the surgical technique difficult in addition to reducing the patient's physical performance. Analyzing the survival rate of implants in young patients, more than 80% is reported in a 25-year follow-up.

INTRODUCCIÓN: una inquietud frecuente en consultas prequirúrgicas de reemplazo total de rodilla es el regreso al ejercicio. El propósito de este estudio fue analizar resultados funcionales y retorno al deporte en pacientes menores de 60 años posterior a esta cirugía. MATERIAL Y MÉTODOS: analizamos retrospectivamente 41 reemplazos totales de rodilla en 36 pacientes deportistas (edad promedio: 53 años [46-60]). Seguimiento promedio de dos años (6 meses-5 años). Diagnósticos: 37 gonartrosis, tres secuelas de artritis reumatoidea, una deformidad extraarticular. Resultados funcionales y radiográficos evaluados mediante Knee Society modificado y High Activity Arthroplasty Score. RESULTADOS: mejoría promedio de 31.95 a 91.61 en KSS y promedio de 7.95 a 13.73 en HAAS. Retorno al deporte en 3.5 meses promedio (rango: 2-6 meses). Tres pacientes no retornaron al deporte. CONCLUSIONES: consideramos que el retraso de la cirugía en estos pacientes producirá progresión en su patología artrósica y cese de sus actividades deportivas. Esto dificulta la técnica quirúrgica además de disminuir el rendimiento físico del paciente. Analizando la tasa de supervivencia de implantes en pacientes jóvenes, se reporta más de 80% en seguimientos de 25 años.

[Avascular necrosis of the femoral head after COVID-19: clinical presentation and management. Clinical-functional outcomes of decompression and supplementation with bone marrow cell aspirate]. / Necrosis avascular de la cabeza femoral tras COVID-19: presentación clínica y manejo. Resultados clínico-funcionales de descompresión y suplementación con aspirado de células de médula ósea.

INTRODUCTION: the pandemic of COVID-19 has led to clinical complications such as avascular necrosis of the femoral head (AVNFH) associated with the use of corticosteroids. The aim of the study is to report the functional and radiographic results of 13 patients with post-COVID-19 ANFH after decompression using Forage and bone marrow aspirate concentrate (BMAC). MATERIAL AND METHODS: single-center, prospective, uncontrolled clinical study. From April 2020 to September 2021, 13 patients (21 hips) with post-COVID-19 ANFH were treated. All received corticosteroids during infection (average daily dose: 480 mg). Clinical, radiographic and magnetic resonance imaging evaluations were performed; the Ficat classification was applied for the classification of AVNFH. The surgical technique used was decompression with Forage and ACMO. RESULTS: the mean age was 47 years, with a follow-up of 30.4 months. Symptoms appeared with a mean of 4.2 months after COVID-19 infection. Harris score improved from 41.2 ± 5.2 to 86.6 ± 3.4. Radiographic evaluation showed that 14.3% of the sample experienced femoral head collapse and underwent total hip arthroplasty. CONCLUSIONS: post-COVID-19 ANFH is a clinical entity with rapid progression and different degrees of severity. Decompression with Forage and ACMO seems a promising initial treatment, however, the variable response and the probability of collapse emphasize the importance of long-term follow-up and identification of patients who may require additional interventions.

INTRODUCCIÓN: la pandemia de COVID-19 ha dado lugar a complicaciones clínicas como la necrosis avascular de la cabeza femoral (NAVCF) asociada con el uso de corticoesteroides. El objetivo del estudio es reportar los resultados funcionales y radiográficos de 13 pacientes con NAVCF post-COVID-19, después de la descompresión utilizando Forage y aspirado de células de medula ósea (ACMO). MATERIAL Y MÉTODOS: estudio clínico unicéntrico, prospectivo, no controlado. Desde Abril de 2020 hasta Septiembre de 2021, se trataron 13 pacientes (21 caderas) con NAVCF post-COVID-19. Todos recibieron corticoesteroides durante la infección (dosis promedio diaria: 480 mg). Se realizaron evaluaciones clínicas, radiográficas y por resonancia magnética nuclear; se aplicó la clasificación de Ficat para la clasificación de NAVCF. La técnica quirúrgica empleada fue descompresión con Forage y ACMO. RESULTADOS: la edad promedio fue 47 años, con un seguimiento de 30.4 meses. Los síntomas aparecieron con una media de 4.2 meses después de la infección por COVID-19. La escala de Harris mejoró de 41.2 ± 5.2 a 86.6 ± 3.4. La evaluación radiográfica demostró que 14.3% de la muestra experimentó colapso de la cabeza femoral por lo que se les realizó artroplastía total de cadera. CONCLUSIONES: la NAVCF post-COVID-19 es una entidad clínica con rápida progresión y diferentes grados de severidad. La descompresión con Forage y ACMO parece un tratamiento inicial prometedor; sin embargo, la respuesta variable y la probabilidad de colapso, enfatizan la importancia de seguimiento a largo plazo e identificación de los pacientes que puedan requerir intervenciones adicionales.

Efficacy of periarticular local infiltrative anaesthesia (modified Ranawat cocktail regimen) for postoperative pain control and reducing morbidity in total knee arthroplasty: a tertiary centre retrospective study.

INTRODUCTION: surgical pain is managed with multi-modal anesthesia in total knee arthroplasty (TKA). It is dubious whether including local infiltrative anaesthesia (LIA) before wound closure provides adequate pain control and decreases morbidity. MATERIAL AND METHODS: this was a retrospective conducted to assess postoperative pain control, morbidity index, and opioid consumption in 116 patients who underwent TKA and were divided into two groups based on LIA (Modified Ranawat Regimen) or normal saline infiltration in the wound. RESULTS: the mean NRS score was significantly lower in LIA group (3.2) as compared to the control group (3.9) in the first 24 hours. Functional milestones were relatively achieved earlier in LIA group but the values were not significant. Tramadol consumption was remarkably higher in the control group as compared to LIA group on day 1 and 2. As per the morbidity index the mean score on day one was 16.18 and 23.40 which decreased to 6.37 and 9.21 by day three in LIA and control group respectively indicating morbidity has decreased but more so in LIA group. CONCLUSION: our study concludes that use of modified cocktail regimen in the knee effectively decreased morbidity with excellent to good results, declining NRS score, minimal rescue analgesia requirement, early ambulation with better safety.

INTRODUCCIÓN: el dolor quirúrgico se trata con anestesia multimodal en la artroplastia total de rodilla (ATR). Es dudoso que incluir anestesia local infiltrativa (LIA) antes del cierre de la herida proporcione un control adecuado del dolor y disminuya la morbilidad. MATERIAL Y MÉTODOS: se realizó una retrospectiva para evaluar el control del dolor posoperatorio, el índice de morbilidad y el consumo de opioides en 116 pacientes sometidos a ATR y se dividieron en dos grupos según el LIA (régimen de Ranawat modificado) o la infiltración de solución salina normal en la herida. RESULTADOS: la puntuación media NRS fue significativamente menor en el grupo LIA (3.2) en comparación con el grupo control (3.9) en las primeras 24 horas. Los hitos funcionales se alcanzaron relativamente antes en el grupo LIA, pero los valores no fueron significativos. El consumo de tramadol fue notablemente mayor en el grupo de control en comparación con el grupo de LIA los días 1 y 2. Según el índice de morbilidad, la puntuación media el día uno fue 16.18 y 23.40, que disminuyó a 6.37 y 9.21 en el día tres en el grupo de LIA y control, respectivamente, lo que indica que la morbilidad ha disminuido, pero más en el grupo LIA. CONCLUSIÓN: nuestro estudio concluye que el uso de un régimen de cóctel modificado en la rodilla disminuyó efectivamente la morbilidad con resultados excelentes a buenos, una disminución de la puntuación NRS, un requisito mínimo de analgesia de rescate y una deambulación temprana con mayor seguridad.

Efficacy and safety of methotrexate plus hydroxychloroquine combination therapy vs. methotrexate monotherapy in the treatment of rheumatoid arthritis: A randomized controlled clinical trial.

OBJECTIVE: To explore the efficacy and safety of combination therapy with methotrexate (MTX) plus hydroxychloroquine (HCQ) vs. MTX monotherapy in patients with rheumatoid arthritis (RA). METHODS: Sixty patients without prior RA treatments were randomly allocated in a 1:1 ratio to two groups: one receiving MTX plus HCQ, and the other receiving MTX monotherapy. We conducted a comparative analysis before and after the 12-week trial, evaluating the visual analogue scale (VAS), the disease activity score in 28 joints (DAS), serum inflammatory factor (including serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α), as well as the outcome of the World Health Organization Quality of Life Brief Version questionnaire (WHOQOL-BREF) and the treatment-emergent adverse events (TEAEs) for all the participants in the study. RESULTS: At the 12th week of the trial, a more remarkable decrease in pain score (VAS), disease activity score (DAS), and serum inflammatory factor levels could be noticed in individuals on the combination therapy. The quality of life score was as well found to be higher in the MTX + HCQ group than the MTX monotherapy group. The incidence of adverse reactions in the MTX + HCQ and the MTX monotherapy groups were 10.00% and 6.67%, respectively. However, no statistical significance could be observed (p > .05). CONCLUSION: In our study, both the MTX + HCQ combination therapy and MTX monotherapy demonstrated improvements in symptoms, conditions and quality of life for patients with RA. Notably, the combination therapy could achieve better outcomes across all indices compared to MTX monotherapy, highlighting its potential as the optimal first-line treatment for RA. © 2024 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.
