RESUMO

BACKGROUND: The aim of the study was to explore the role of recurrent TNM (rTNM) staging in predicting prognosis for ipsilateral breast tumor recurrence (IBTR) and determine the optimal treatment strategy for IBTR. METHOD: IBTR cases were identified from the Surveillance, Epidemiology, and End Results (SEER) database spanning the years 2000-2018. Cox proportional hazards analysis was performed to examine factors associated with overall survival (OS) and breast cancer-specific survival (BCSS). Propensity score matching (PSM) was employed to match IBTR with primary early breast cancer (EBC) based on clinicopathological characteristics. Investigations into the impact of different therapies were also included. RESULTS: Of the 4375 IBTR cases included in the study, the 5-year OS was 87.1%, 71.6% and 58.7% in rTNM stages I, II and III, respectively. After PSM, while IBTR patients had worse survival to primary EBC patients, prognosis of IBTR for different rTNM stage always closely aligned with the corresponding stage of primary EBC. Repeat breast-conserving surgery (BCS) with radiation therapy was equivalent to mastectomy with respect to OS and BCSS. Chemotherapy was favorable for OS and BCSS in estrogen receptor (ER)-negative IBTR or IBTR occurring within a 60-month interval. CONCLUSIONS: rTNM staging system has an outstanding prognostic value for survival outcome of patients with IBTR, and IBTR and primary EBC may have potentially analogous features in the context of TNM staging. BCS plus radiation therapy may be an alternative. IBTR cases who have experienced recurrence with short intervals and with ER-negative tumors might benefit from chemotherapy.

RESUMO

BACKGROUND: World Health Organisation (WHO) and USA Centers for Disease Control and Prevention (U.S. CDC) recommendations now allow simultaneous administration of COVID-19 and other vaccines. We compared antibody responses after coadministration of influenza and bivalent COVID-19 vaccines in the same (ipsilateral) arm vs. different (contralateral) arms. METHODS: Pre- and post-vaccination serum samples from individuals in the Prospective Assessment of COVID-19 in a Community (PACC) cohort were used to conduct haemaglutination inhibition (HI) assays with the viruses in the 2022-2023 seasonal influenza vaccine and focus reduction neutralisation tests (FRNT) using a BA.5 SARS-CoV-2 virus. The effect of ipsilateral vs. contralateral vaccination on immune responses was inferred in a model that accounted for higher variance in vaccine responses at lower pre-vaccination titers. FINDINGS: Ipsilateral vaccination did not cause higher influenza vaccine responses compared to contralateral vaccination. The response to SARS-CoV-2 was slightly increased in the ipsilateral group, but equivalence was not excluded. INTERPRETATION: Coadministration of influenza and bivalent COVID-19 vaccines in the same arm or different arms did not strongly influence the antibody response to either vaccine. FUNDING: This work was supported by the U.S. CDC (grant number: 75D30120C09259).

RESUMO

BACKGROUND: There is limited data on retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI) via ipsilateral epicardial collaterals (IEC). AIMS: To compare the clinical and angiographic characteristics, and outcomes of retrograde CTO PCI via IEC versus other collaterals in a large multicenter registry. METHODS: Observational cohort study from the Prospective Global registry for the study of Chronic Total Occlusion Intervention (PROGRESS-CTO). RESULTS: Of 4466 retrograde cases performed between 2012 and 2023, crossing through IEC was attempted in 191 (4.3%) cases with 50% wiring success. The most common target vessel in the IEC group was the left circumflex (50%), in comparison to other retrograde cases, where the right coronary artery was most common (70%). The Japanese CTO score was similar between the two groups (3.13 ± 1.23 vs. 3.06 ± 1.06, p = 0.456); however, the IEC group had a higher Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS-CTO) score (1.95 ± 1.02 vs. 1.27 ± 0.92, p < 0.0001). The most used IEC guidewire was the SUOH 03 (39%), and the most frequently used microcatheter was the Caravel (43%). Dual injection was less common in IEC cases (66% vs. 89%, p < 0.0001). Technical (76% vs. 79%, p = 0.317) and procedural success rates (74% vs. 79%, p = 0.281) were not different between the two groups. However, IEC cases had a higher procedural complications rate (25.8% vs. 16.4%, p = 0.0008), including perforations (17.3% vs. 9.0%, p = 0.0001), pericardiocentesis (3.1% vs. 1.2%, p = 0.018), and dissection/thrombus of the donor vessel (3.7% vs. 1.2%, p = 0.002). CONCLUSION: The use of IEC for retrograde CTO PCI was associated with similar technical and procedural success rates when compared with other retrograde cases, but higher incidence of periprocedural complications.

RESUMO

BACKGROUND: Mastectomy has been the standard surgical treatment for ipsilateral breast tumor recurrence (IBTR). Recently, there has been growing interest in repeat breast-conserving surgery (rBCS) for IBTR among breast surgeons; however, there is currently little information regarding patient preferences for surgical procedure for IBTR. The purpose of this study was to evaluate preference for surgical procedure (mastectomy vs. rBCS) among breast cancer patients who had undergone salvage surgery for IBTR. METHODS: Overall, 100 breast cancer patients who had undergone salvage surgery for IBTR were asked about their preferred surgical methods for IBTR and the reason. The association of patient preference and the reasons related to various clinical and pathological factors were assessed. RESULTS: Of the 100 respondents, only 11 patients (11%) preferred rBCS. Patients who had undergone rBCS and radiotherapy for IBTR were significantly more likely to prefer to undergo rBCS than other groups (p = 0.030). The most frequent reason for choosing rBCS was the patient's desire to minimize breast deformity and surgical wounds. CONCLUSIONS: Our study revealed that there is a low rate of patients who opt to undergo rBCS among patients who had undergone salvage surgery for IBTR. Discrepancies in perceptions regarding the surgical procedure for IBTR between patients and their surgeons may exist.

RESUMO

Introduction: Migraine is a common clinical disorder, ranks as the second most disabling disease worldwide, and often manifests with unilateral onset. Contralateral acupuncture (CAT), as a classical acupuncture method, has been proven to be effective in the treatment of migraine without aura (MWoA). However, its neural mechanisms have not been investigated using multimodal magnetic resonance imaging (MRI). Methods and analysis: In this multimodal neuroimaging randomized trial, a total of 96 female MWoA participants and 30 female healthy controls (HCs) will be recruited. The 96 female MWoA participants will be randomized into three groups: Group A (CAT group), Group B [ipsilateral acupuncture (IAT) group], and Group C (sham CAT group) in a 1:1:1 allocation ratio. Each group will receive 30 min of treatment every other day, three times a week, for 8 weeks, followed by an 8-week follow-up period. The primary outcome is the intensity of the migraine attack. Data will be collected at baseline (week 0), at the end of the 8-week treatment period (weeks 1-8), and during the 8-week follow-up (weeks 9-16). Adverse events will be recorded. Multimodal MRI scans will be conducted at baseline and after 8-week treatment. Discussion: This study hypothesized that CAT may treat MWoA by restoring pathological alterations in brain neural activity, particularly by restoring cross-integrated functional connectivity with periaqueductal gray (PAG) as the core pathological brain region. The findings will provide scientific evidence for CAT in the treatment of MWoA. Ethics and dissemination: The Medical Ethics Committee of the Second Affiliated Hospital of Yunnan University of Chinese Medicine has given study approval (approval no. 2022-006). This trial has been registered with the Chinese Clinical Trials Registry (registration no. ChiCTR2300069456). Peer-reviewed papers will be used to publicize the trial's findings.

RESUMO

Introduction: The incidence of ipsilateral fracture of the shaft of the femur and dislocation of the hip are extremely rare injuries. However, the incidence of complex fractures is increasing day by day due to an increasing variety of traumatic mechanisms. This type of injury constitutes various diagnostic and treatment difficulties for the surgeon. Such injuries should be managed on an urgent basis for better functional outcomes. Case Report: We hereby describe two such cases: First case hip was reduced using external fixator pins, stabilization of the shaft femur fracture was done with an external fixator and the second case hip was reduced with bone holding clamps and the shaft femur fracture was fixed with interlocking nail. Conclusion: Fixator-assisted closed reductions are the first line of treatment in the management of posterior dislocation hip complicated with ipsilateral femoral shaft fractures. If closed reduction fails, fracture site can be opened and direct forces can be applied to the proximal femur to aid hip reduction with minimum complications.

RESUMO

Zinner syndrome, a rare congenital anomaly affecting males, is characterized by atresia of the ejaculatory duct, seminal vesicle cysts, and ipsilateral renal agenesis. This case report details a 2-year-old boy successfully treated with laparoscopic excision of a dilated vas deferens and seminal vesicle cyst. The rarity of Zinner syndrome in pediatric patients underscores the importance of understanding its diagnosis and minimally invasive surgical management.

RESUMO

Purpose of the study The current study had two goals: first, it compared the radiological and functional results of the ipsilateral shaft and proximal femur fractures treated by using two different methods, i.e., single implant vs dual implants. The second goal was to devise a clinical algorithm for guiding and managing such fractures. Methods This study was conducted in a level 1 trauma center and included 34 patients with concomitant ipsilateral fractures of the proximal femur and shaft of the femur. The patients were divided into two groups as per our clinical algorithm. Group I, comprising of 16 patients, were treated with a single implant like the proximal femoral nail (PFN) or proximal femoral nail antirotation (PFNA2). Group II of dual implants, comprising of 18 patients, were treated with two types of implants separately for proximal and shaft fracture. Results All patients were followed at monthly intervals up to six months, then at three monthly intervals up to one year, with a minimal follow-up of one year of every patient. On clinical evaluation by Friedman-Wyman criteria, in group I, seven patients had a fair outcome, eight patients had a good outcome, and one patient had a poor outcome, while in group II, eight patients had a fair outcome, nine patients had a good outcome, and one patient had a poor outcome. No patient developed non-union or avascular necrosis of the femoral head in any of the groups. Conclusion For concurrent ipsilateral diaphyseal and proximal femur fractures, both dual and single implants are equally effective alternatives if properly applied as per our clinical algorithm. Implant selection primarily depends on the pattern of injury, and our clinical algorithm can be a suitable guide for guiding the selection of implants.

RESUMO

Introduction: Subchondral insufficiency fracture (SIF) of the femoral head has been reported to occur in older women with osteoporosis. No cases with recurrence of SIF at another site in the ipsilateral femoral head have been described. Case Report: We report a case of a 75-year-old woman with recurrent SIF at another site in the ipsilateral femoral head. SIF was first observed at an anterolateral site on the femoral head and treated non-operatively. The hip pain disappeared after 3 months but recurred 5 months later when another SIF was newly observed at a posterolateral-to-medial site on the femoral head. This SIF was also treated non-operatively. Five months later, the pain was alleviated, but progression of osteoarthritis was seen on X-rays. Conclusion: After an initial SIF, the possibility of recurrence should be considered if pain recurs, even on the ipsilateral side.

RESUMO

INTRODUCTION: The recent ACOSOG Z11102 trial demonstrated low recurrence rates with breast conserving surgery (BCS) in women with multiple ipsilateral breast cancers (MIBC). Questions remain regarding the oncologic safety of BCS in women with MIBC receiving neoadjuvant chemotherapy (NAC). METHODS: We conducted a retrospective cohort study of adult patients who underwent BCS following NAC for stage I-III breast cancer from 2012 to 2021 at two academic centers. Descriptive statistics were used to summarize the data and the Kaplan-Meier method was used to provide estimates for recurrence and survival outcomes. MIBC was defined as ≥2 foci of malignancy. RESULTS: A total of 544 patients were included; 29.4% (n = 160) ER+/HER2-, 17.7% (n = 96) ER+/HER2+, 18.2% (n = 99) ER-/HER2+, and 34.7% (n = 189) with ER-/HER2-disease. Overall, 80.5% (n = 438) had unifocal breast cancer while 19.5% (n = 106) had MIBC. Of patients with MIBC, 90.6% (n = 96) had multifocal and 9.4% (n = 10) had multicentric disease. Pathologic complete response was achieved in 41.1% of patients with MIBC versus 41.5% of patients with unifocal disease (p = 0.94). At a median follow-up of 55 months (IQR 32-83); 4.8% of patients in the unifocal group and 4.7% of patients in the MIBC group had had a local recurrence (p = 0.97). There was no difference in 5-year local recurrence-free survival (p = 0.92), recurrence-free survival (p = 0.06), or overall survival (p = 0.07) between the groups. CONCLUSION: In this large cohort of women undergoing BCS post-NAC, there was no significant difference in in breast tumor recurrence or survival outcomes between patients with unifocal disease and those with MIBC.

RESUMO

(1) Background: The wider adoption of a preoperative ultrasound and calcitonin screening complemented by an intraoperative frozen section has increased the number of patients with occult sporadic medullary thyroid cancer (MTC). These advances offer new opportunities to reduce the extent of the initial operations, minimizing operative morbidity and the risk of postoperative thyroxin supplementation without compromising the cure. (2) Methods: This systematic review of the international literature published in the English language provides a comprehensive update on the latest progress made in the risk-adapted surgery for sporadic and hereditary MTC guided by an intraoperative frozen section. (3) Results: The current evidence confirms the viability of a hemithyroidectomy for desmoplasia-negative sporadic MTC. To add an extra safety margin, the hemithyroidectomy may be complemented by a diagnostic ipsilateral central node dissection. Despite the limited extent of the surgery, all the patients with desmoplasia-negative sporadic tumors achieved a biochemical cure with excellent clinical outcomes. A hemithyroidectomy decreases the need for postoperative thyroxine substitution, but a total thyroidectomy may be required for bilateral nodular thyroid disease. Hereditary MTC is a different issue. Because each residual thyroid C cell carries its own risk of malignant progression, a total thyroidectomy remains mandatory for hereditary MTC. (4) Conclusion: In experienced hands, a hemithyroidectomy, which minimizes morbidity without compromising the cure, is an adequate therapy for desmoplasia-negative sporadic MTC.

RESUMO

Purpose The Re-irradiation and the Breast Cancer Working Groups of the Italian Association of Radiotherapy and Clinical Oncology (AIRO) conducted a survey to provide an overview of the policies for breast cancer (BC) re-irradiation (re-RT) among the Italian radiotherapy (RT) centers. Methods In October 2021, 183 RT centers were invited to answer a survey: after an initial section about general aspects, the questionnaire focused on radiation oncologists’ (ROs) attitude toward re-RT in three different scenarios: ipsilateral breast tumor recurrence (IBTR) treated with second conservative surgery, IBTR treated with mastectomy and inoperable IBTR. Surveyed ROs were also asked to express their interest in being involved in a prospective trials. Results Seventy-seven/183 (42.0%) centers answered the Survey, only one RO per center was requested to answer. In particular, 86.5% ROs declared to have performed “curative” re-RT for IBTR during the previous two years (2019–2020): 76.7% respondents administered re-RT after second BCS, 50.9% after mastectomy, and 48.1% for inoperable IBTR. Re-RT practice varied widely among centers in terms of treatment volumes, dose and fractionation schedules, techniques and dose-volume constraints for organs at risks (OARs). Forty-six participants (59.7%) expressed their interest in participating in a prospective study investigating BC re-RT. Conclusions About one out of three RT centers in Italy delivered re-RT for IBTR. Nevertheless, practice of re-RT varied widely among centers highlighting the needs for prospective studies to improve knowledge in this field (AU)

RESUMO

INTRODUCTION AND IMPORTANCE: Ipsilateral proximal, shaft, and distal femur fractures are extremely uncommon. It might be challenging and contentious to treat ipsilateral multi-level femur fractures. There are still unanswered questions regarding the order of fracture types that should be repaired first and the type of implant that should be used. CASE PRESENTATION: A twenty-nine-year-old male patient was assessed at the emergency department after a motorcycle accident. The patient had a clearly deformed left lower extremity and was complaining of pain in the left thigh. Preoperative radiographs revealed ipsilateral multi-level femur fracture on the left thigh involved basicervical fracture of femur (AO/OTA 31-B3) with transverse shaft fracture of femur (AO/OTA 32-A3) and extra articular supracondylar femur fracture (AO/OTA 33-A2). CLINICAL DISCUSSION: First, we performed proximal femur nail antirotation in order to stabilize the fracture of the femur neck and reduce the incidence of nonunion and avascular necrosis of the femoral head in young adults. The next step to fix the shaft and distal femur fracture was to perform the distal femur locking plate. The EQ5D and Harris Hip Score questionnaires showed improvement after implementing these procedures. CONCLUSION: Ipsilateral multi-level femur fractures have challenges and controversies in their management. In this situation, proximal femur nail antirotation and distal femur locking plates are viable options due to the condition of the injury and the higher risk of negative effects. After all fractures have been fixed, it is important to closely monitor the hip and knee joints to avoid stiffness or contracture.

RESUMO

Ipsilateral hip and knee dislocation is a rare and complex injury that usually results from high-energy trauma. Only 14 cases were reported in the literature so far. We report the case of a 35-year-old man who presented with an ipsilateral right hip and knee dislocation after being involved in a road traffic accident. A contralateral floating knee was associated. The hip dislocation was associated to a posterior wall fracture of the acetabulum and a femoral head fracture. The knee dislocation was compound and associated with a patella fracture. The hip dislocation was reduced. The posterior wall and the femoral head fractures were treated conservatively. The knee dislocation was reduced and stabilized by external fixator. Early postoperative infection occurred and was treated surgically. At the last follow-up, the knee was ankylosed at 5° of flexion with a bony bridge between the femoral condyle and the tibial plateau. The patient described an occasional hip pain on exertion. He had full range of motion of the right hip. No avascular necrosis of the femoral head was seen. Outcomes of simultaneous hip and knee dislocation are very variable and remain unpredictable. The timing of reducing the hip joint and the knee.

RESUMO

Aiming at the problems of small sample size and large feature dimension in the identification of ipsilateral supraclavicular lymph node metastasis status in breast cancer using ultrasound radiomics, an optimized feature combination search algorithm is proposed to construct linear classification models with high interpretability. The genetic algorithm (GA) is used to search for feature combinations within the feature subspace using least absolute shrinkage and selection operator (LASSO) regression. The search is optimized by applying a high penalty to the L1 norm of LASSO to retain excellent features in the crossover operation of the GA. The experimental results show that the linear model constructed using this method outperforms those using the conventional LASSO regression and standard GA. Therefore, this method can be used to build linear models with higher classification performance and more robustness.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the impact of the ipsilateral arm position on ipsilateral shoulder pain after lung cancer resection by video-assisted thoracic surgery. DESIGN: A prospective randomized controlled trial. SETTING: A single academic center study. PARTICIPANTS: Patients undergoing video-assisted thoracic surgery pulmonary resection for cancer at the Institut Universitaire de Cardiologie et de Pneumologie de Québec from May 2020 to May 2022 were included. INTERVENTIONS: Patients randomly were assigned with a 1:1 ratio to a supported or suspended ipsilateral arm position. MEASUREMENTS AND MAIN RESULTS: Ipsilateral shoulder pain incidence, pain score, and opioid use were recorded in the postanesthesia care unit (PACU) on postoperative days 1 and 2. One hundred thirty-three patients were randomized, 67 in the suspended-arm group and 66 in the supported-arm group. Of the patients, 31% reported ipsilateral shoulder pain in the PACU with no difference between groups (19/67 [28.4%] v 22/66 patients (33.3%), p = 0.5767). There was no significant difference between the pain score in the PACU (3 [0-6] v 4 [0-6], p = 0.9055) at postoperative day 1 (4 [2-6] v 3 [2-5], p = 0.4113) and at postoperative day 2 (2 [0-5] v 2 [1-4], p = 0.9508). Ipsilateral shoulder pain score decreased rapidly on postoperative day 2. There was no statistical difference in opioid and gabapentinoid use between the groups. CONCLUSIONS: Ipsilateral arm position seems to have no impact on ipsilateral shoulder pain.

RESUMO

Mirror therapy (MT) has been proposed to promote motor recovery post-stroke through activation of mirror neuron system, recruitment of ipsilateral motor pathways, or/and increasing attention toward the affected limb. However, neuroimaging evidence for these mechanisms is still lacking. To uncover the underlying mechanisms, we designed a randomized controlled study and used a voxel-based whole-brain analysis of resting-state fMRI to explore the brain reorganizations induced by MT. Thirty-five stroke patients were randomized to an MT group (n â€‹= â€‹16) and a conventional therapy (CT) group (n â€‹= â€‹19) for a 4-week intervention. Before and after the intervention, the Fugl-Meyer Assessment Upper Limb subscale (FMA-UL) and resting-state fMRI were collected. A healthy cohort (n â€‹= â€‹16) was established for fMRI comparison. The changes in fractional amplitude of low-frequency fluctuation (fALFF) and seed-based functional connectivity were analyzed to investigate the impact of intervention. Results showed that greater FMA-UL improvement in the MT group was associated with the compensatory increase of fALFF in the contralesional precentral gyrus (M1) region and the re-establishment of functional connectivity between the bilateral M1 regions, which facilitate motor signals transmission via the ipsilateral motor pathways from the ipsilesional M1, contralesional M1, to the affected limb. A step-wise linear regression model revealed these two brain reorganization patterns collaboratively contributed to FMA-UL improvement. In conclusion, MT achieved motor rehabilitation primarily by recruitment of the ipsilateral motor pathways. Trial Registration Information: http://www.chictr.org.cn. Unique Identifier.

RESUMO

Purpose: The purpose of this study is to describe a case of unilateral keratoconus associated with ipsilateral craniofacial fibrous dysplasia and its subsequent management with corneal collagen cross-linking. Observations: This is an interventional case report of a 16-year-old male with a history of polyostotic fibrous dysplasia of the left frontal bone and orbital roof status post partial resection six years prior who presented to the pediatric ophthalmology clinic with progressively blurry vision in the left eye. Refraction in this eye revealed an increase in cylinder by > 3D from his last refraction two years prior. Pentacam corneal tomography confirmed the diagnosis of keratoconus in the left eye. The patient underwent corneal collagen cross-linking in the affected eye. Postoperatively, he experienced marked improvement in corrected visual acuity with scleral contact lenses and maintained stable astigmatism and keratometry values on Pentacam corneal tomography at his most recent visit 12 months postoperatively. Conclusions: While it is otherwise felt to be a bilateral disease, unilateral keratoconus may present in the context of ipsilateral orbital pathology. Corneal collagen cross-linking may be used to successfully prevent keratoconus progression in the setting of stable orbital pathology.

RESUMO

Background: Anterior dislocation of the shoulder associated with a diaphyseal fracture of the ipsilateral humerus is a rare and controversial occurrence, with very few cases reported in the literature. Case presentation: We present a case of a 39-year-old right-handed driver who presented with an anterior dislocation of the shoulder associated with a diaphyseal fracture of the ipsilateral humerus following a road traffic accident. The lateral approach to the fracture allowed us to use two forceps to gain a good grip on the proximal fragment and perform the maneuver to reduce the dislocation. The fracture was reduced and fixed with a molded Lecestre-type plate. Conclusion: In this case, we employed the approach of initially reducing the shoulder dislocation with forceps, followed by osteosynthesis of the humeral fracture. The functional results were excellent after 6 months.

RESUMO

PURPOSE: A "floating hip" (FH) injury is a rare injury describing the simultaneous ipsilateral fracture of the femur and pelvis or acetabulum (P/A). We describe our experience with patients presenting with FH injuries and compare them to controls with similar P/A fractures but without femoral involvement. METHODS: Medical records and radiographs of FH patients and controls presenting to our tertiary centre between 2015 and 2020 were reviewed. Follow-up data from outpatient clinical records were also extracted. The control group were extensively matched by age, sex, body mass index, fracture classification and energy of injury. RESULTS: From 1392 recorded P/A fractures, 42 FH cases were identified (average age 39 years, 78.6% males). The most common femoral fracture was the midshaft (35.7%), followed by the neck of femur (26.2%). 90.5% of FH injuries were due to high-energy mechanisms. 64.3% of P/A fractures, and 100% of femoral fractures were managed surgically. Compared to controls, FH cases were more likely to have additional orthopaedic injuries (73.8% vs. 40.5%, p = 0.002), more total theatre admissions (mean 2.5 vs. 1.19, p < 0.001), longer hospital stays (28.3 vs. 14.9 days, p = 0.02), and a higher rates of post-op complications (53.8% vs. 20%, p = 0.025). CONCLUSIONS: We report differences in the presentation, management, and outcomes of FH injuries versus controls, even after extensive matching for confounders. These differences may inform future treatment strategies for the FH injury.
