RESUMO

PURPOSE: To report a case of Cogan-Like Syndrome following treatment with nivolumab for metastatic cutaneous melanoma. METHODS: A case report. RESULTS: A 54-year-old female sought a second opinion from us regarding the recently diagnosed uveitis in both eyes. She had a diagnosis of metastatic cutaneous melanoma in the right arm and was undergoing treatment with nivolumab. Four weeks following the initiation of nivolumab therapy, she experienced tinnitus and bilateral sensorineural hearing loss, which was treated with oral and intratympanic steroids. While tapering the oral steroids, she developed iridocyclitis with papillitis in both eyes. This combination of vestibuloauditory symptoms and ocular inflammation was strikingly reminiscent of Cogan's syndrome. Because of the timing in relation to the nivolumab therapy and the steroid responsiveness of her presentation, this was speculated to be due to immune overactivation from the nivolumab. Given her complex condition, which involved toxicity and multiple metastases, the patient was advised to consider either topical and/or local corticosteroids or intravenous immunoglobulin. The patient chose to persist with corticosteroid therapy. CONCLUSION: Nivolumab could potentially be linked to an immune-related condition resembling Cogan syndrome. In cases involving patients with a complex condition necessitating nivolumab treatment, the use of topical and/or local corticosteroids or intravenous immunoglobulin, might constitute the sole viable treatment options.

RESUMO

PURPOSE: To evaluate outcomes of intravenous (IV) tocilizumab (TCZ) in patients with pars planitis refractory to conventional immunomodulatory therapy and anti-tumor necrosis factor (TNF) alpha agents. METHODS: Medical records of eight patients diagnosed with pars planitis and treated with monthly 4 or 8 mg/kg IV TCZ were reviewed. The primary objective was to initiate and sustain remission continuously for three consecutive months. Secondary outcome measures were changes in best corrected visual acuity (BCVA), degree of anterior chamber (AC) inflammation, vitreous cell, vitreous haze, presence of vitreous or pars plana exudates, peripheral vasculitis, fluorescein angiography (FA) score and central subfieldthickness (CST) on macular optical coherence tomography (OCT). RESULTS: Fourteen eyes of eight patients were treated with IV TCZ. Seven patients were women. The average age was 31.35 ± 16.42 years. In 6 (75%) out of 8 patients, IV TCZ, either as monotherapy or in combination with another conventional immunomodulatory agent, induced and sustained remission. The average FA score reduced from 11.15 ± 3.52 at the baseline visit to 6.50 ± 2.12 at the one-year follow-up visit (p-value < 0.05). None of the patients experienced any side effects of IV TCZ. CONCLUSION: IV Tocilizumab (TCZ) may represent an effective and safe treatment option for patients diagnosed with pars planitis resistant to conventional immunomodulatory therapy and anti-TNF alpha agents.

RESUMO

Purpose: To report a case of carboplatin-induced bilateral optic neuropathy in a patient with metastatic squamous cell carcinoma of the tongue. Case Report: A 65-year-old man with a history of squamous cell carcinoma of the tongue with metastasis to the right axillary lymph node treated with carboplatin and paclitaxel was evaluated for decreased visual acuity in both eyes. Visual acuity was 20/70 in the right eye and no light perception in the left eye. On dilated fundus examination, optic disc edema was present in both eyes with more severity in the left eye, flame shape hemorrhages around the optic nerve head in both eyes and cotton wool spots around the left optic nerve head. Brain and orbital MRI demonstrated enhancement of the bilateral optic nerve sheaths. He was diagnosed with bilateral carboplatin-induced optic neuropathy. Conclusion: Our findings in this case justify monitoring of patients during their course of intravenous carboplatin therapy.

RESUMO

In this study, we report paracentral acute middle maculopathy (PAMM) and cotton wool spots (CWS) in a patient with ocular migraine. A 74-year-old man presented with persistent paracentral scotoma in the right eye that began a week prior. His visual acuity was 20/25 in the right eye and 20/40 in the left. Dilated fundoscopy revealed CWS in the right eye. Spectral-domain optical coherence tomography (SD-OCT) showed hyper-reflective bands in the inner nuclear layer corresponding to parafoveal lesions seen on near-infrared imaging in the right eye consistent with the diagnosis of PAMM. Further laboratory studies were unremarkable, and a transthoracic echocardiogram and a carotid ultrasound were unrevealing. The patient was started on brimonidine three times daily in both eyes. The patient reported subjective improvement in the paracentral scotoma and the absence of ocular migraine symptoms at two-month follow-up. We conclude from this case that PAMM and CWS can occur simultaneously in ocular migraine, and we suggest that retinal vascular changes associated with ocular migraine may contribute to ischemia underlying both entities. Additionally, we suggest a potential therapy in brimonidine due to its proposed beneficial effects on retinal vasculature and neuroprotection.

RESUMO

INTRODUCTION: This study delves into the management of acromion fractures and acromioclavicular (AC) joint dislocations-orthopedic injuries with significant implications for shoulder function. Despite their infrequency, these injuries present challenges due to potential persistent pain and functional limitations. Current treatment strategies span from conservative measures to surgical interventions, yet there exists a notable gap in comprehensive data on specific surgical approaches. PRESENTATION OF CASE: We present a compelling case involving a 38-year-old male athlete who sought medical attention following a motor vehicle accident due to severe right shoulder pain. Upon admission to the emergency ward, the patient reported an inability to move the affected shoulder. Radiographic evaluations, comprising X-ray and computerized tomography scans, revealed a displaced fracture at the base of the acromion coupled with an AC dislocation. A novel surgical technique was employed, featuring coracoid fixation with mersilene thread and a 2-hole reconstruction plate-a distinctive approach in the field. DISCUSSION: The systematic rehabilitation plan yielded successful healing and the restoration of normal shoulder function, offering promising insights into potential advancements in orthopedic practices. CONCLUSION: This case contributes valuable knowledge to the understanding of these complex injuries, paving the way for further exploration and refinement in their management. The innovative surgical approach showcased underscores the importance of continued research and exploration to enhance the overall treatment landscape for acromion fractures and AC joint dislocations.

RESUMO

Purpose: In this study, we report a patient who presented with both chronic myelocytic leukemia (CML) and Susac syndrome (SS). Observations: A 45-year-old male diagnosed with CML in the blast phase sought consultation due to a deterioration in vision in his right eye. He also had hearing loss and severe migraneous headaches. Best corrected visual acuity was light perception and 20/20 in the right and left eyes, respectively. The slit lamp examination and intraocular pressure were within normal ranges for both eyes. Upon dilated fundoscopy, organized vitreous hemorrhage was observed in the right eye, while the left eye exhibited extensive sclerotic vessels with retinal neovascularization in the periphery. Ultrasound of the right eye showed tractional retinal detachment. Optical coherence tomography of the left retina showed thinning of the retina in temporal macula. Fluorescein angiography revealed a substantial nonperfused region in the peripheral left retina, accompanied by arterioarterial and arteriovenous collaterals, along with microaneurysms. MRI showed scattered foci of hyperintensity within the supratentorial white matter, mostly subcortical on T2-weighted and fluid-attenuated inversion-recovery. The patient received a diagnosis of SS and was subsequently referred to the neurology service for further assessment and potential treatment. Conclusion and importance: SS may manifest as a presentation of CML. It is advisable to conduct investigations for SS in CML patients experiencing neurological, ophthalmological, or otological symptoms.

RESUMO

Introduction: Blau syndrome is a progressive disease with an unknown etiology and pathogenesis. It can cause severe damage, especially in the eye with severe involvement. Case Presentation: A six-year-old female was referred to us complaining about blurry vision and floaters in both eyes for 1 year. She had been diagnosed with Blau syndrome and Blau syndrome-associated anterior uveitis. Her best-corrected visual acuity in the right and left eyes was 20/70 and 20/80, respectively. Slit-lamp exam revealed faint bilateral band keratopathy along with 1+ anterior chamber cells and posterior synechia 360° in both eyes. During dilated fundoscopy, 2+ haze in the media was observed, along with swollen and hyperemic disc OU. Based on changes in optical coherence tomography, fluorescein angiography, and indocyanine green angiography, she was diagnosed with panuveitis and retinal vasculitis. Given her complicated history, we decided to proceed with an intravitreal fluocinolone acetonide 0.19 mg implant implantation in both eyes. During the 1-month follow-up visit, vitreous haze, retinal vasculitis, and active choroiditis were resolved. At 6-month follow-up visit, no changes were observed compared to the 1-month follow-up visit. Conclusion: In cases of Blau syndrome that display resistance to systemic immunomodulatory therapies, the inclusion of local treatments, such as the intravitreal fluocinolone acetonide 0.19 mg implant, should be considered as an adjunctive therapeutic option.

RESUMO

Treatment anxiety is a serious problem among child patients. A few studies have addressed this issue with virtual reality solutions, with promising results; however, the applications used have generally been designed for entertainment instead of this purpose. This article studies the potential of using deep breathing exercises in a virtual natural environment to address this issue, with a focus on design approach and user experience. It presents the VirNE-Virtual Natural Environments relaxation application, which is based on known stress-reduction methods, and a feasibility study conducted with it in a local hospital. The study had a within-subjects design, and it included 21 eight to twelve-year-old child patients, who used the application during an intravenous cannulation procedure related to their treatment. The study found good user acceptance and user experience both among the child patients and pediatricians, with the perceived usefulness of the method being higher among the patients with increased levels of anxiety or needle phobia. In addition, a clear stress-reducing effect was found. This offers proof-of-concept for the multidisciplinary design approach based on existing scientific knowledge regarding the desired effect for pediatric virtual reality applications for this use context.

RESUMO

There exists a need for new methods to address treatment anxiety in pediatrics-at the same time, deep breathing exercises and virtual natural environments have both been known to have stress-reducing qualities. This article reports the combined effect of these two methods in a pediatric setting. A feasibility study was conducted in a local hospital. The study had a within-subjects design, and it included 21 child patients aged 8 to 12 years old, who used a virtual reality (VR) relaxation application developed for this purpose during an intravenous cannulation procedure related to their treatment. The key findings highlight a statistically very significant stress reduction associated with the utilized VR intervention, demonstrated by heart rate variability measurements (SDNN, p < 0.001; RMSSD, p = 0.002; Stress Index, p < 0.001; LF/HF ratio, p = 0.010). This effect was consistent regardless of the level of general anxiety or the level of needle phobia of the patient, and no adverse effects were observed. The results show the strong potential of using deep breathing exercises in virtual natural environments for addressing treatment anxiety related to invasive pediatric procedures.

RESUMO

PURPOSE: Introduce a unique case of primary vitreoretinal lymphoma with a new optical coherence tomography finding. METHODS: A case report. A 67-year-old healthy man with complaints of blurry vision in his right eye. RESULTS: The patient's visual acuity was 20/60 and 20/20 in the right and left eyes, respectively. Anterior segment exam of the right eye demonstrated mild inflammation. Dilated fundoscopy revealed 2+ vitreous haze and 4+ disc edema. Optical coherence tomography of the macula in the right eye revealed optic nerve head swelling and thickening of the retina. Fluorescein angiography demonstrated mild leakage and staining of vessels along the inferotemporal arcade in the right eye. Labs were within normal limits except positive Herpes simplex virus 1 IgG. Initially, the patient was treated for herpetic panuveitis for three weeks with a favorable response. However, the clinical condition deteriorated as a new abnormality was identified in the macular region of the right eye through optical coherence tomography. Considering intraocular lymphoma as a potential diagnosis, the patient underwent a diagnostic vitrectomy. The vitreous sample analysis confirmed PVRL through immunohistochemistry and flow cytometry. The patient exhibited a rapid response following the initiation of intravenous and intravitreal methotrexate treatment. CONCLUSION: The presence of subretinal fluid accompanied by suspended hyperreflective lesions originating from the roof of the subretinal fluid pocket on the OCT of macula "stalactite sign" might serve as a characteristic sign indicative of primary vitreoretinal lymphoma; however, further investigation using robust studies is necessary to examine this hypothesis.

RESUMO

BACKGROUND: Open reduction and internal fixation have been described as the gold standard for the treatment of acetabular fractures, but the high complications of these surgeries have led surgeons to seek less invasive procedures. In recent years, minimally invasive treatment, such as fixation through the skin have been proposed. The aim was to assess acetabular fracture outcomes of combination of posterior approach (Kocher-Langenbeck [KL]) with anterior percutaneous screw fixation (APSF) with minimally invasive surgery (MIS). METHODS: Between February 2017 and July 2019, 155 patients with acetabular fractures underwent fixation with the KL + APSF approach. For 1 year functional outcomes, radiographic findings, and postoperative complications were evaluated. RESULTS: Of 155 patients with a mean age of 40.16 ± 10.32 years, 82 patients were male and 73 were female. The most common pattern of fracture was both columns (32.9%). The average blood loss was approximately 527 ml. The average operation time was 85 min. The mean length of surgical incision was 113.3 mm. Harris' hip score was excellent in 75.5% of cases. The mean VAS score was approximately 4 and 91.6% of patients returned to pre-trauma activity. In 74.8% of cases, the reduction was anatomical. Complications after surgery were very insignificant and included the following: 2 patients had foot drop within 5 months both patients recovered, 2 patients had femoral nerve palsy and 3 cases of deep vein thrombosis and 1 case of pulmonary thromboembolism were treated. There were four patients with surgical site infections, all of whom recovered and two of the seven patients with osteoarthritis underwent total hip arthroplasty. CONCLUSION: Combining posterior approach with minimally invasive anterior method in fixation and treatment of acetabular fractures is a safe and reliable method and showed significant functional results with minimal complications.

RESUMO

INTRODUCTION: Juvenile idiopathic arthritis is the most common chronic rheumatologic disease in children. Uveitis is the most common extra-articular manifestation of JIA, and it can be a sight-threatening condition. AREAS COVERED: In this review article, we discussed epidemiology, risk factors, clinical presentation, supportive laboratory tests, treatment options, and complications of Juvenile idiopathic arthritis and Juvenile idiopathic arthritis associated uveitis. We covered conventional immunomodulatory therapy and biologic response modifiers agents for different types of Juvenile idiopathic arthritis and their associated uveitis. Finally, we discussed the course of disease, functional outcome, and the quality of life of Juvenile idiopathic arthritis and Juvenile idiopathic arthritis-associated uveitis. EXPERT OPINION: Although clinical outcomes of Juvenile idiopathic arthritis and its associated uveitis have been improved over the past three decades by biologic response modifier agents, a significant proportion of patients require active treatment into adult life therefore screening and monitoring of these patients is required during the patient's entire life. The limited number of food and drug administration approved biologic response modifier agents for the treatment of Juvenile idiopathic arthritis associated uveitis justify more randomized clinical trials with new medications in this field.

RESUMO

Background: Angular deformities of the lower extremities are among the most common findings in pediatric orthopedics. Alteration of the mechanical axis in the lower extremity affects the cosmetic appearance and may lead to gait disturbances, knee discomfort, patellar maltracking with or without pain, and early joint osteoarthritis. In the current study, we aimed to investigate the efficacy of 3-hole 3.5 mm reconstruction plates in tension-band temporary hemiepiphysiodesis for correcting idiopathic knee coronal angular deformities. Methods: The surgical procedure was performed using an extraperiosteal tension band plate (a 3-hole reconstruction plate) and two 3.5 mm cortical screws to treat idiopathic knee coronal angular deformity in children. The location of the hemiepiphysiodesis was determined based on the type of angular deformity present. Postoperative follow-ups were conducted through x-rays to measure the medial proximal tibial angle and lateral distal femoral angle of the limbs. Statistical analysis was then performed to evaluate the efficacy of the surgical treatment based on the rate of alignment change exhibited. Results: The study included 14 patients (25 limbs) with genu valgum deformity who underwent temporary hemiepiphysiodesis on both the distal femur and proximal tibia, with 16 proximal tibias and 15 distal femurs being corrected. The correction rate for genu valgum was found to be 0.59° per month for both proximal tibial and distal femoral hemiepiphysiodesis. Six patients (12 limbs) were also identified with genu varum deformity, and the correction rates for proximal tibial lateral hemiepiphysiodesis and distal femoral lateral hemiepiphysiodesis were 0.85° and 0.15° per month, respectively. During a mean follow-up duration of 11 ± 5.7 months, only one case of physeal plate closure was observed, and there were no other significant complications. Conclusion: Temporary hemiepiphysiodesis with a 3-hole R-plate and two cortical screws takes advantage of physiological physeal growth to successfully treat idiopathic angular deformities with low complication rates.

RESUMO

Thromboembolic events as a result of COVID-19 mRNA vaccination are a rare, though life-threatening complication. In this case report, we describe a 40-year-old female patient who developed central retinal artery and ophthalmic artery occlusion progressing to intracranial thrombosis 3 weeks after vaccination with the Pfizer-BioNTech COVID-19 vaccine. Initially, she presented with progressive acute and painless unilateral vision loss in her left eye. Dilated fundoscopy of left eye showed macular whitening with sparing of the area of cilioretinal artery distribution. Labs revealed a normal erythrocyte sedimentation rate, C-reactive protein, and platelet count. Computerized tomography angiography of the head and neck showed an occlusion of the entire left cervical internal carotid artery and occlusion of the origin of the left external carotid artery. Despite treatment with heparin, her vision declined to no light perception. Ten days later, the patient presented with right peripheral vision loss and was found to have a new left posterior cerebral artery/posterior inferior cerebellar artery stroke. Seventeen days later, she presented to the hospital with nausea and vertigo and was found to have a subacute infarction in the left parietal lobe corresponding to left anterior communicating artery/middle cerebral artery watershed territory. Hypercoagulable disorders, vasculitis, cardiac arrhythmias, and intraventricular thrombi were excluded. Fundus fluorescein angiography confirmed central retinal artery occlusion and ophthalmic artery occlusion with impressive retina and choroid changes in fluorescein angiography patterns. This complication of mRNA COVID-19 vaccination has not been previously described in the literature and should be considered even weeks after initial presentation.

RESUMO

PURPOSE: To report a case of nonparaneoplastic autoimmune retinopathy with phenotypical features of pericentral retinal degeneration (PRD) who responded to IV immunoglobulin therapy. METHODS: A case report. A 27-year-old man presented with recent subacute progressive nyctalopia and photopsia. RESULTS: Dilated fundoscopy demonstrated confluent yellow-white patches along the main temporal vascular arcades with sparing of the central island in the posterior pole. Color vision, fundus autofluorescence, fluorescein angiography, static visual field, and electroretinographic studies were inconclusive for retinal degeneration. Subsequent genetic testing for known mutations was negative. Workup for paraneoplastic autoimmune retinopathy was negative. Antiretinal antibodies were positive. The patient was diagnosed with nonparaneoplastic autoimmune retinopathy and was treated with IV immunoglobulin, which resulted in objective and subjective improvement on electroretinography, visual field, and optical coherence tomography of the retina. CONCLUSION: Nonparaneoplastic autoimmune retinopathy may present in a patient with the clinical phenotype of PRD. It is essential to rule out nonparaneoplastic autoimmune retinopathy in patients with subacute changes in the natural course of pericentral retinal degeneration because treatment with IV immunoglobulin may be helpful.

RESUMO

OBJECTIVE: To compare the demographic, clinical, ancillary testing, and multimodal imaging characteristics of birdshot chorioretinopathy (BSCR) patients with late recurrence and birdshot patients with durable remission. PATIENTS AND METHODS: This was a retrospective observational case series. The above-mentioned parameters were studied in BSCR patients with late recurrence (group 1) and BSCR patients with durable remission (group 2). RESULTS: Fifty-five patients were included in this study. The average age of patients was 62.1 ± 11.1 years (range, 35-88 years). Groups 1 and 2 included 20 (36.4%) and 35 (63.6%) patients, respectively. In group 1, the average age of patients was 60.5 ± 10.39 years (range, 35-79 years). The female-to-male ratio was 16:4. In group 2, the average age of patients was 63.1 ± 11.6 years (range, 37-88 years). The female-to-male ratio was 22:13. None of the demographic, clinical, ancillary testing, and multimodal imaging parameters were statistically significantly different between the two groups. Using a receiver operating characteristics (ROC) curve, we found that the ideal duration of successful therapy to induce durable remission was 30 months with 70% sensitivity and 40% specificity (ideal point on the curve). A Kaplan-Meier survival curve demonstrated that late recurrence was seen within 30 months after stopping successful treatment of patients with BSCR. CONCLUSION: There are no demographic, clinical, ancillary testing, or multimodal imaging characteristics that can predict late recurrence in BSCR patients. However, we found that 30 months of successful treatment may be ideal and recommended.

RESUMO

AIM: To evaluate the effect of repository corticotropin injection (RCI) on regulatory T cell population in patients with noninfectious retinal vasculitis. PATIENTS AND METHODS: Patients with active noninfectious retinal vasculitis were included in a prospective nonrandomized open-label study. RESULTS: Eighteen patients (33 eyes) were included in the study. Eleven (61.1%) patients [20 (60.6%) eyes] and 7 (38.9%) patients [13 (33.3%) eyes] were in the responsive and non-responsive groups, respectively. We did not find any statistically significant difference within the PPP-R group, within the PPP-NR group, or between these two groups in regard to regulatory T cell population. No significant systemic or ocular complications were found. CONCLUSION: RCI may be a complementary treatment in patients with non-infectious retinal vasculitis with or without uveitis. This study did not demonstrate an increase in regulatory T cell population in patients with noninfectious retinal vasculitis.

RESUMO

PURPOSE: To search findings that can explain the heterogeneity between Resistant and Responsive patients with birdshot chorioretinopathy. PATIENTS AND METHODS: This was a retrospective observational case series on "Responsive" versus "Resistant" birdshot chorioretinopathy. RESULTS: One-hundred-eighty and Ninety-nine patients were included in the Responsive and Resistant groups respectively. Multivariate analysis of paraclinical variables at the first visit demonstrated that mean deviation (p = .04), pattern standard deviation (p < .001), optic nerve head leakage (p = .012), large vessel leakage and staining (p = .01), and macular small vessel leakage (p = .03) were statistically significantly different between the two groups; however, at the visit preceding successful therapy, only macular small vessel leakage (p = .01) was statistically significantly different between the two groups. CONCLUSION: .Small vessel leakage in the macular area and/or optic nerve head leakage at the earliest visit might be risk factors for resistant birdshot chorioretinopathy.

RESUMO

PURPOSE: To report a case of acute macular neuroretinopathy (AMN) after intravitreal triamcinolone acetonide (TRIESENCE®) injection for cystoid macular edema secondary to birdshot chorioretinopathy. METHOD: A case report. PATIENT: A 62-year-old female. RESULTS: The patient presented with acutely decreased vision and a ring scotoma around her central vision three days after intravitreal triamcinolone acetonide (TRIESENCE®) injection for cystoid macular edema in her right eye (OD) secondary to birdshot chorioretinopathy. She had undergone pars plana vitrectomy, cataract extraction, and secondary intraocular lens implantation OD three months prior to the recent injection. Best-corrected visual acuity (BCVA) was 20/1000 OD and 20/50 OS. Intraocular pressure was 21 mmHg OD and 12 mmHg OS. Fluorescein angiography demonstrated a hypofluorescent area in the perifoveal zone OD. Optical coherence tomography OD depicted hyperreflective areas in the outer nuclear layer, outer plexiform layer, and retinal pigment epithelium. We diagnosed her with AMN OD and started her on brimonidine three times a day OD. She came back a week later with resolved scotoma and her vision improved to 20/60 OD. Five weeks later, BCVA was 20/40 and Intraocular pressures (IOP) was 12 mmHg OD. CONCLUSIONS AND IMPORTANCE: Intravitreal triamcinolone injection may be a cause of AMN with cystoid macular edema (CME) and borderline-high intraocular pressure. Brimonidine may be an effective treatment for these patients in the early course of the disease.

RESUMO

Background: Studies have proved that in addition to the inlet and outlet views, the intraoperative lateral sacral view is required to ensure the correct entry point, reduce operating time, and lower radiation exposure. Considering the complex anatomy of the sacrum, we showed a safe corridor for sacroiliac joint (SIJ) screw insertion that was accessible using only inlet and outlet fluoroscopic views. Methods: From 2013 to 2020, we enrolled 215 patients who underwent percutaneous SIJ screw insertion. Our experience in SIJ screw insertion is presented using only two views (inlet and outlet). We reported on the radiation exposure time, operating time, rate of screw malposition, neurologic injury, and revision surgery. Results: The screw malposition rate was 5.5%, including 11 foraminal perforations and one perforated anterior sacral cortex. Paresthesia after the surgery was observed in six patients (2.8%). No revision surgery or screw removal was performed. The radiation exposure and operation time for each screw were 21 ± 4.5 s and 13.5 min, respectively. Conclusion: The most anterior and the lowest part of the S1 vertebra can be easily found using intraoperative inlet and outlet views. It is a safe corridor for SIJ screw insertion with low radiation time, neurologic injury, and revision rates.
