RESUMO

Significance: Oral cancer surgery requires accurate margin delineation to balance complete resection with post-operative functionality. Current in vivo fluorescence imaging systems provide two-dimensional margin assessment yet fail to quantify tumor depth prior to resection. Harnessing structured light in combination with deep learning (DL) may provide near real-time three-dimensional margin detection. Aim: A DL-enabled fluorescence spatial frequency domain imaging (SFDI) system trained with in silico tumor models was developed to quantify the depth of oral tumors. Approach: A convolutional neural network was designed to produce tumor depth and concentration maps from SFDI images. Three in silico representations of oral cancer lesions were developed to train the DL architecture: cylinders, spherical harmonics, and composite spherical harmonics (CSHs). Each model was validated with in silico SFDI images of patient-derived tongue tumors, and the CSH model was further validated with optical phantoms. Results: The performance of the CSH model was superior when presented with patient-derived tumors ( P -value < 0.05 ). The CSH model could predict depth and concentration within 0.4 mm and 0.4 µ g / mL , respectively, for in silico tumors with depths less than 10 mm. Conclusions: A DL-enabled SFDI system trained with in silico CSH demonstrates promise in defining the deep margins of oral tumors.

RESUMO

Significance: Intraoperative molecular imaging (IMI) enables the detection and visualization of cancer tissue using targeted radioactive or fluorescent tracers. While IMI research has rapidly expanded, including the recent Food and Drug Administration approval of a targeted fluorophore, the limits of detection have not been well-defined. Aim: The ability of widely available handheld intraoperative tools (Neoprobe and SPY-PHI) to measure gamma decay and fluorescence intensity from IMI tracers was assessed while varying characteristics of both the signal source and the intervening tissue or gelatin phantoms. Approach: Gamma decay signal and fluorescence from tracer-bearing tumors (TBTs) and modifiable tumor-like inclusions (TLIs) were measured through increasing thicknesses of porcine tissue and gelatin in custom 3D-printed molds. TBTs buried beneath porcine tissue were used to simulate IMI-guided tumor resection. Results: Gamma decay from TBTs and TLIs was detected through significantly thicker tissue and gelatin than fluorescence, with at least 5% of the maximum signal observed through up to 5 and 0.5 cm, respectively, depending on the overlying tissue type or gelatin. Conclusions: We developed novel systems that can be fine-tuned to simulate variable tumor characteristics and tissue environments. These were used to evaluate the detection of fluorescent and gamma signals from IMI tracers and simulate IMI surgery.

RESUMO

Disc nucleus replacement (NR) is a challenging surgical technique used as a medical treatment for early-stage disc herniation to restore disc height and the biomechanical function of a motion segment, which may reduce low back pain. The surgical procedure involves the removal and replacement of the degenerated nucleus pulposus with a substitute by accessing the annulus fibrosos via a created hole. Over the decades, nucleus replacement has been an important issue, leading to the development of different substitute alternatives. The first ideas are dated to the 1950s and since then, more than a hundred nucleus replacement concepts can be identified. There were numerous attempts and several clinical trials; however, after more than 70 years of research, no gold standard for nucleus pulposus replacement has been identified. This review aims to collect the different nucleus replacements reported in the literature, thus understanding what failed, what could be improved and what are the opportunities for the future. A systematic review of the literature was performed using a keyword-based search on PubMed, Web of Science, and Scopus databases to detect all nucleus replacements presented in the past by clinicians and engineers. Several studies were extracted from which the main nucleus replacements over the years were investigated, including the ones that received CE mark, FDA approval, or IDE approval and, also those involved in clinical trials. A total of 116 studies were included in this review. The extracted data concern the nucleus replacements proposed over the years to create a historical background as complete as possible, including their mechanical and biomechanical characterization and the clinical trials conducted over the years. Nucleus disc arthroplasty has been explored for many years. Unfortunately, even today there is still nothing safe and definitive in this surgical practice. This review provides an overview of the nucleus replacement history. A breakthrough could be the improvements in technologies for the annulus fibrous closing or sealing and the tissue engineering and medical regenerative techniques which could certainly ensure a higher NR implantation success rate in the future of this clinical treatment. It is not yet clear what is the future of this clinical practice. Only scientific research can answer the question: is the nucleus replacement still a possible clinical solution?

RESUMO

Significance: Near-infrared autofluorescence (NIRAF) utilizes the natural autofluorescence of parathyroid glands (PGs) to improve their identification during thyroid surgeries, reducing the risk of inadvertent removal and subsequent complications such as hypoparathyroidism. This study evaluates NIRAF's effectiveness in real-world surgical settings, highlighting its potential to enhance surgical outcomes and patient safety. Aim: We evaluate the effectiveness of NIRAF in detecting PGs during thyroidectomy and central neck dissection and investigate autofluorescence characteristics in both fresh and paraffin-embedded tissues. Approach: We included 101 patients diagnosed with papillary thyroid cancer who underwent surgeries in 2022 and 2023. We assessed NIRAF's ability to locate PGs, confirmed via parathyroid hormone assays, and involved both junior and senior surgeons. We measured the accuracy, speed, and agreement levels of each method and analyzed autofluorescence persistence and variation over 10 years, alongside the expression of calcium-sensing receptor (CaSR) and vitamin D. Results: NIRAF demonstrated a sensitivity of 89.5% and a negative predictive value of 89.1%. However, its specificity and positive predictive value (PPV) were 61.2% and 62.3%, respectively, which are considered lower. The kappa statistic indicated moderate to substantial agreement (kappa = 0.478; P < 0.001 ). Senior surgeons achieved high specificity (86.2%) and PPV (85.3%), with substantial agreement (kappa = 0.847; P < 0.001 ). In contrast, junior surgeons displayed the lowest kappa statistic among the groups, indicating minimal agreement (kappa = 0.381; P < 0.001 ). Common errors in NIRAF included interference from brown fat and eschar. In addition, paraffin-embedded samples retained stable autofluorescence over 10 years, showing no significant correlation with CaSR and vitamin D levels. Conclusions: NIRAF is useful for PG identification in thyroid and neck surgeries, enhancing efficiency and reducing inadvertent PG removals. The stability of autofluorescence in paraffin samples suggests its long-term viability, with false positives providing insights for further improvements in NIRAF technology.

RESUMO

BACKGROUND: The ventral and distal aspects of the corpora cavernosa are the thinnest, increasing the likelihood of cylinder extrusion or crossover complications pertaining to inflatable penile prosthesis procedures. A double distal corporal anchoring double stitch can be used to robustly secure impending lateral extrusions and crossovers of implant cylinders. It is a novel, effective corrective measure for the uncommon complication of migrated cylinders in inflatable penile prosthesis placement. AIM: To describe the surgical indications and technique for the double distal corporal anchoring fixation stitch for lateral penile implant cylinder extrusion. METHODS: We discuss a double-stitch technique that is performed following corporoplasty and capsulotomy. A lateral incision is made subcoronally on the affected side to identify the crossover or lateral extrusion. The cylinder is repositioned properly within the native corpora to prevent further cylinder migration. Two 2-0 Ethibond sutures are threaded through the distal cylinder eyelet, and each suture is delivered through the glans with a Keith needle and tied off. An incision is made in the glans, and 1 arm of each suture is tied with the other to create a bridge between the sutures that can be positioned deep within the skin of the glans. OUTCOMES: Over the past 4 years, 66 patients with lateral cylinder extrusion underwent the double distal corporal anchoring fixation stitch procedure, with overall improved satisfaction (97%). Only 2 patients had surgical complications. One patient experienced repeated lateral extrusion of the penile implant cylinders 6 weeks following the double-anchoring stitches procedure. The second patient developed a painful suture granuloma that necessitated excision, which resolved this issue, and the penile implant cylinder remained in the proper position over a year later. CLINICAL IMPLICATIONS: This technique ensures the secure fixation of the affected cylinders in the surgical capsule by creating a bridge between 2 sutures holding each repositioned cylinder in place, and the ensuing fibrotic reaction helps to fixate the extruded cylinder within the midglandular tissue. STRENGTH AND LIMITATIONS: This surgical technique describes the double distal corporal anchoring stitch for lateral penile implant cylinder extrusion. Further studies are warranted to validate long-term outcomes and satisfaction. CONCLUSION: The double distal corporal anchoring fixation stitch is a safe and efficacious method to secure cylinders in the proper surgical capsule during revision procedures to correct distal crossovers or laterally extruded penile prosthesis implants.

RESUMO

Traditionally, percutaneous nephrolithotomy (PCNL) includes placing a nephrostomy tube and a Double J (DJ) stent to drain the kidney and operative tract following the procedure. However, more recent techniques, such as tubeless or totally tubeless PCNL, eliminate these drainage methods. The objective was to assess the feasibility, safety and effectiveness of performing tubeless or totally tubeless PCNL in comparison to standard PCNL a retrospective analysis was performed on 156 patients who underwent PCNL treatment From September 2022 to September 2023. Of these, 78 patients received traditional nephrostomy PCNL, while 46 patients underwent the tubeless procedure and the remaining 32 received the totally tubeless procedure. The three groups showed no significant differences in preoperative patient characteristics. The operation time, analgesic requirements and hospital stay were lower in the tubeless and totally tubeless PCNL group than in the standard PCNL group (p<0.05). No significant differences were found in the mean stone size, stone-free status or the occurrence of major complications. The overall complications (Grade-1, 2 and 3) rate was 14.2% in the standard PCNL group, 8.7% in the tubeless PCNL and 9.4% in the totally tubeless PCNL group. The tubeless and totally tubeless PCNL techniques have proven to be safe and effective, even for patients with incomplete staghorn stones and a moderate pelvic stone burden. These approaches are associated with reduced pain, lower analgesic needs, shorter operative times, and decreased hospital stays, making them more cost- effective and less likely to result in complications, while also improving patient satisfaction. Further research is essential to validate the safety of these techniques, encouraging urologists to adopt them in clinical practice.

RESUMO

The treatments of subtrochanteric femoral fractures are a challenge. It accounts about 10.0% to 34.0% of all hip fractures with a high complication rate. This area consists of mostly cortical bone with high stress generation thus heal slowly. The fracture is too proximal to adequately control with implants for femoral shaft and too distal to control with implants for intertrochanteric fractures. The intrinsic insecurity of this fracture and forces of the muscles with comminuted medial calcar is giving the fracture a tendency to varus crumple. Extramedullary implants are associated with higher rate of implant failure while intramedullary nails are not suitable for short proximal segment and wide medullary canal. Recently proximal femoral locking compression plate (PF-LCP) has been applied in treatment of proximal femur including subtrochanteric fractures. It has an excellent result in respect of union, fewer complications and early rehabilitation. The aim of this study was to assess the rate and time taken for union of fractures by PF-LCP and determine perioperative parameters. This prospective study was conducted from March 2019 to September 2020 at Mymensingh Medical College Hospital through non randomized purposive sampling. Total 25 patients aged above 18 years irrespective of sex with closed subtrochanteric fracture were included but pathological fractures, multiple injuries were excluded from the study. Union status evaluated by Radiographic Union Score for Tibial (RUST) fracture of Whelan; where antero-posterior and lateral radiographs (X-ray) based assessment of healing of the four cortices done. The entity cortical scores were added to give an entire score; 4 being the least amount demonstrating fracture are positively not healed and 12 being the highest score representing that the fracture is positively healed. The mean age of the patients was 42.04±14.97 years with range 22-70 years. Majority of patients were male (60.0%) and most of injury (64.0%) due to road traffic accident with most fractures was Seinsheimer type III (48.0%). Average operative time was 121.92 minutes, follow up period was 41.12 weeks (24-48 weeks) and time taken for union was 14.16 weeks (11-28 weeks). According to RUST scores; fracture union rate 88.0% with delayed union 12.0% and no nonunion. There were two patients with superficial wound infection and no implant failure. This study concludes that PF-LCP is a safe and reliable implant for the treatment of subtrochanteric femoral fractures.

RESUMO

Achilles tendon injury has been increasing over recent years due to a variety of causes. The injury of the Achilles tendon is a disabling condition, which is difficult to treat if there is a gap or defect between the two ends of the disrupted tendon. Patients with a rupture of the Achilles tendon should be operated without delay. Most of the people in our country use flat pan in the latrine, which are at a same level of the toilet floor. Surface of the toilet pan breaks down and cause sharp cut. Some of the cases of open tendon injuries occur due to road traffic accident, cut by broken glass and also assault. It is generally accepted that surgical repair of fresh ruptures of the Achilles tendon gives excellent results. Objective of the study was to find out the evaluation of the results of primary repair of Open tendo-achilles injury (OTAI). This prospective study was done in the department of Casualty of Mymensingh Medical College Hospital, Bangladesh in the period of Octy 2021 to June 2022. Patients who came with OTAI in casualty department were selected randomly. All cases were selected as OTAI, without associated injury of other leg muscles, posterior tibial artery and nerve within 12 hours. All patients underwent primary end to end repair by Modified Kessler's method. Evaluation of the results of primary repair of OTAI were carried out and were find out the common causes of injury, age and sex incidence, level of injury and to proposed a protocol for treating such cases in comfortable, cheap and convenient way for the patients. Operations were done at Casualty operation theatre (COT). Then 48 patients were followed up at the Department of Casualty. Among them 43(89.58%) of patients were able to stand on tip toes, 4(08.33%) of patients were not stand on tip toes of affected foot unsupported but able to stand on tip toes supported, 1(02.08%) of patients failed to stand on affected foot unsupported due to severe infection and wound gap. Final result were Excellent - 29(60.0%), Good - 14(30.0%), Fair - 4(8.0%), Poor - 1(2.0%). Repair of OTAI is not difficult but early diagnosis, proper surgical toileting, meticulous repair; adequate post-operative management is the key of success. So, the result of this study, treatment protocol can be followed, which is easy for surgeon and convenient and cheap for the patients.

RESUMO

There are many women in Bangladesh who suffer from chronic shoulder pain, back and neck pain, nerve pain, and other difficulties due to large breasts but most of them are not keen to get rid of their problems. Most women in this country are afraid from surgery and they are not even aware about their body shape and images. Recently, very few of them are coming to the door of surgeons with enlarged breast difficulties. A study was conducted on reduction mammaplasty regarding experience in the context of our country. Few of the patients were motivated among many who have problems of the huge breast and perform reduction mammaplasty. The paper addresses the experience of reduction mammaplasty. The study among 8 patients was performed in, Anower Khan Modern Medical College and Hospital and Care Medical College and Hospital during the period of Octy 2018 to January 2021. The patients underwent reduction mammaplasty over a 2.5 years period were identified and reviewed for patients satisfaction rate, religious issues, shyness, Family restrictions, socio economic condition, lack of awareness, risk factor, symptom relief, limitation and complication rate. Rate of complications was from 6.5% to 22% for reduction mammaplasty, whereas reported patient satisfaction rates range from 85.0% to 95.0%. In the study, reported rates of symptom improvement range from 80.8% to 94.6%, religious issues about 90.0% to 95.0%, Shyness 80.0% to 87.5%, family restrictions 80% to 87.5%, socio economic condition (High Class n=5, Upper Middle Class n=3), risk factor 70.0% to 80.0%, but in regard to psychological well-being there are tremendous outcomes. Reduction mammaplasty has had excellent patient satisfaction levels. However, a very few complications may occur even in the most suitable candidate. Skilled and experienced surgeons, enriched healthcare infrastructures, meticulous pre-operative planning, gentle tissue handling and anticipatory post-operative care will reduce the incidence of adverse results.

RESUMO

Ossification of sacrospinous ligament induces a great risk for maintaining the stability of the pelvis. The sacrospinous ligament, along with the sacrotuberous ligament, plays a distinct role in the sacroiliac joint and pubic symphysis stability. The ossification may cause compression of neurovascular structure traversing through the greater and lesser sciatic foramen. Here we report a case of unilateral heterogenous ossification of the left sacrospinous ligament causing sciatic nerve compression and sciatic pain. A 22-year-old Bangladeshi woman, mother of one child, presented with complaints of pain in the lower back, left buttock and back of the upper thigh. Clinical examination and investigations revealed a diagnosis of the partially ossified sacrospinous ligament with sciatic nerve compression. Total excision of heterotrophic calcification and partial excision of left sacrospinous ligament through posterior approach by a left paramedian incision over the lower back was performed under general anaesthesia. On outpatient follow-up visits at 2 weeks and 6 weeks post-surgery, complete disappearance of pain was observed, and the patient was able to return to regular productive life activity. In this report, we presented a rare case of ossified sacrospinous ligament causing sciatic nerve compression with unknown etiology. The surgical approach performed, total excision of heterotrophic calcification and partial excision of left sacrospinous ligament through the posterior approach helped to preserve the pelvic stability with a good clinical outcome.

RESUMO

BACKGROUND: The ablation of atrioventricular nodal reentrant tachycardia (AVNRT) with cryoablation is an alternative to radiofrequency (RF) ablation in patients due to the low risk of total atrioventricular block. An increase in early-late recurrences after cryoablation is reported as an important disadvantage. OBJECTIVES: In this study, we aimed to compare the acute procedural success and the long-term recurrence rates of patients, with AVNRT who underwent methods. METHODS: 73 patients with AVNRT were included in the study: 32 with cryoablation and 41 with RF ablation. There was no statistically significant difference between acute procedural success in methods. The ablation procedure was performed by an operator experienced in arrhythmology. The choice of RF or cryoablation was made in the electrophysiology laboratory based on the material already available during the procedure. After the procedure, the patients were evaluated every 3 months for 2 years in polyclinic control. The significance level adopted in the statistical analysis was 5%. RESULTS: The 2 groups of patients were homogeneous. The fluoroscopy time (p<0.001) was shorter, but atrium-his (p=0.004) and his-ventricular (p=0.015) times were longer in the cryoablation group. There was no significant difference, in terms of acute procedural success, post-procedure jump without a single echo, and presence of echo and jump. CONCLUSIONS: Cryoablation requires less fluoroscopy time and is a safe non-inferior alternative to RF ablation in patients with AVNRT. The risk of AV block is a significant problem with the use of RF energy, making it less suitable for use in young and physically active patients.


FUNDAMENTO: A ablação da taquicardia por reentrada nodal atrioventricular (TRNAV) com crioablação é uma alternativa à ablação por radiofrequência (RF) em pacientes devido ao baixo risco de bloqueio atrioventricular total. Um aumento nas recorrências precoces e tardias após a crioablação é relatado como uma desvantagem importante. OBJETIVOS: Neste estudo, objetivamos comparar o sucesso do procedimento agudo e as taxas de recorrência em longo prazo de pacientes com TRNAV submetidos a métodos. MÉTODOS: Foram incluídos no estudo 73 pacientes com TRNAV: 32 com crioablação e 41 com ablação por RF. Não houve diferença estatisticamente significativa entre o sucesso agudo do procedimento nos métodos. O procedimento de ablação foi realizado por operador com experiência em arritmologia. A escolha entre RF ou crioablação foi feita no laboratório de eletrofisiologia com base no material já disponível durante o procedimento. Após o procedimento, os pacientes foram avaliados a cada 3 meses durante 2 anos em controle policlínico. O nível de significância adotado na análise estatística foi de 5%. RESULTADOS: Os dois grupos de pacientes foram homogêneos. O tempo de fluoroscopia (p<0,001) foi menor, mas os tempos his-átrio (p=0,004) e his-ventricular (p=0,015) foram maiores no grupo crioablação. Não houve diferença significativa em termos de sucesso agudo do procedimento, salto pós-procedimento sem eco único e presença de eco e salto. CONCLUSÕES: A crioablação requer menos tempo de fluoroscopia e é uma alternativa segura e não inferior à ablação por RF em pacientes com TRNAV. O risco de bloqueio AV é um problema significativo com o uso de energia de RF, tornando-o menos adequado para uso em pacientes jovens e fisicamente ativos.

RESUMO

BACKGROUND: Stereotactic approaches to diffuse intrinsic pontine gliomas (DIPGs) remain essential due to advances in molecular biology and management, necessitating tissue sampling. Here we present an effective technique with a biopsy by robot-assisted transcerebellar approach. METHOD: Our procedure was performed using the ROSA robotic system and the OARM CT scan, which provided stereotactic conditions for this transcerebellar approach to brainstem lesions. CONCLUSION: The robot-assisted transcerebellar stereotactic approach remains essential to provide complications for biopsy of brainstem lesions.

RESUMO

OBJECTIVE: To describe the study design and procedures of the incontinence post robot- assisted radical prostatectomy, anatomical and functional causes (IPA) trial. This trial aims to identify and study patient and procedure specific factors leading to urinary incontinence post robot-assisted laparoscopic radical prostatectomy (RALP). MATERIAL AND METHODS: The IPA study is a prospective, multicentre, open non-randomised surgical trial, including patients prior to RALP and registered on-line (ISRCTN67297115). IPA is administered from the Department of Urology at Sahlgrenska University Hospital, Gothenburg, Sweden. Patients undergo an anatomical and functional evaluation using magnetic resonance imaging (MRI), urodynamics including cystometry, pressure-flow and urethral pressure profile, and dynamic transrectal ultrasound prior to and 3 months after RALP. The incontinence data are gathered using patient reported outcome measure questionnaires. The primary endpoint is incontinence at 3 months after RALP, defined as need of any pad. The secondary endpoints are incontinence 12 months post RALP defined as need of any pad, and 3- and 12-months post RALP, defined as use of more than a safety pad. RESULTS: Until October 2023, 207 patients have been included of the stipulated 1,000, with an increasing rate of accrual. Out of these patients,187 have had a pre- and post-operative MRI and 177 have undergone pre- and post-operative urodynamics. CONCLUSIONS: The design of the IPA study, together with promising accrual and coming multicentre inclusion, will hopefully result in the identification, and deeper understanding, of the various risk-factors for post-RALP incontinence. This could improve information and decision making regarding adequate treatment for patients with prostate cancer.

RESUMO

This paper aims to investigate the impact of conventional rehabilitation training and neuromuscular electrical stimulation (NMES) on the recovery of motor abilities in patients following ligament injury reconstruction. Forty postoperative patients who underwent surgery for anterior cruciate ligament reconstruction (ACLR) were randomly allocated to either the conventional rehabilitation group or the NMES group. The NMES group received NMES treatment in addition to the conventional rehabilitation program starting from eight weeks postoperatively. Various parameters, including knee joint function, stability, and balance, were compared between the two groups at eight weeks and 12 weeks postoperatively. Compared to the data at eight weeks postoperatively, both groups exhibited significant improvements in all measured indicators at 12 weeks postoperatively (p < 0.05). In the 12th week after the surgery, the NMES group demonstrated a Lysholm score of 93.18 ± 3.67 points, an IKDC score of 84.65 ± 2.33 points, a KT-2000 measurement of 0.88 ± 0.45 mm, a thigh circumference difference of -1.33 ± 0.55 cm, a knee flexion angle of 130.12 ± 4.21°, a single-leg standing time of 60.12 ± 9.33 s, a YBT score of 70.26 ± 2.68 points, and a Bulgarian split squat 1RM size of 58.07 ± 6.85 kg; all of these results were significantly superior to those observed in the conventional group (p < 0.05). NMES significantly enhances the recovery of athletic ability in patients following postoperative ACLR and can be effectively applied in clinical practice.

RESUMO

OBJECTIVE: This study aimed to describe cases of cesarean scar pregnancies that were successfully treated with suction curettage under ultrasound guidance and their outcome. METHODS: This retrospective, descriptive case-series study was performed on 17 patients diagnosed with cesarean scar ectopic pregnancy in Sulaimani Maternity Teaching Hospital from May 2022 to April 2023. The patients' sociodemographic and clinical data were collected. The patients were treated with suction curettage alone or in combination with local injection of methotrexate under ultrasound guidance. RESULTS: Patients with a viable fetus (n = 4) received local intrinsic methotrexate injection into the gestational sac and suction curettage, while those in whom the fetus had died (n = 13) underwent only suction curettage. Five patients required intrauterine balloon insertion to stop bleeding without further treatment, and only three required a blood transfusion owing to severe bleeding. CONCLUSIONS: Cesarean scar ectopic pregnancy is a dangerous and complex disorder with an increasing occurrence in recent years. Accurate early diagnosis and effective management are essential to reduce maternal mortality and mortality of this type of pregnancy.

RESUMO

INTRODUCTION: Traditional risk stratification systems based on the clinicopathological criteria have limitations and may not accurately predict outcomes for all patients. The neurologic, oncologic, mechanical, and systemic (NOMS) framework aims to optimise treatment outcomes and improve patient care. Here, we aimed to provide a comprehensive overview of the NOMS framework within the context of spinal metastasis. MATERIALS AND METHODS: The study rigorously followed the guidelines set by PRISMA. We conducted an extensive search and be as transparent as possible across wellregarded databases such as PubMed and Euro PMC. The primary outcome measure focused on examining the feasibility of implementing the NOMS framework for patients with spinal metastasis in real-world clinical settings, and this measure was predefined and justified. RESULTS: This systematic review included three studies involving 300 participants with spinal metastases at the cervicothoracic junction. The studies examined surgical interventions like decompression, fusion and corpectomy within the NOMS framework. Across the studies, the NOMS approach is consistently associated with adverse outcomes, including complication rates, surgical revisions, hardware complications, deformities, tumour recurrence and variable survival rates. It is also linked to hospital stays, ICU durations and specific discharge statuses. Another study focused on spinal metastasis patients undergoing endoscopic surgery, highlighting the NOMS framework's connection to recurrence rates, performance metrics, neurological status, pain management, functional recovery and quality of life. In addition, other studies explored navigated instrumentation, with a primary focus on screw placement accuracy. All three studies demonstrated methodological rigor by reporting adequate allocation concealment. CONCLUSION: NOMS framework consistently associates with adverse spinal metastasis surgery outcomes.

RESUMO

Background and purpose:

Mechanical thrombectomy is the most important treatment modality in acute stroke; despite successful thrombectomy, good functional outcome is not achieved in a significant proportion of patients. This study examined the effect of neutrophil lymphocyte ratio (NLR) values at admission on functional outcomes in successfully recanalized patients.

. Methods:

Patients who underwent mechanical thrombectomy due to anterior system major vessel occlusion were retrospectively analyzed and compared with the admission NLR values and 3-month clinical modified Rankin Scale (mRS) scores of successfully recanalized patients.

. Results:

Of a total of 126 patients who underwent thrombectomy within the specified period, 97 patients with successful recanalization were included in the study. The overall successful recanalization rate was calculated as 77%. The mean NLR of patients with mRS ≤2 (n=65) was found to be significantly lower than patients with mRS≥3 (n=32) (p<0.001). A weak and significant correlation was found between National Institutes of Health Stroke Scale (NIHSS) value and NLR (r= 0.315, p=.002).

. Conclusion:

NLR value has been found to be associated with futile recanalization in me­chanical thrombectomy patients. There­fore, we think that suppression of inflammation before thrombectomy will increase the chan­ce of successful thrombectomy.
