Postoperative hip bracing reduces kinesiophobia in patients undergoing hip arthroscopy: a randomized-controlled trial.

INTRODUCTION: Detailed postoperative rehabilitation protocols after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) are still a matter of debate. Adjunctive hip bracing represents a promising tool to improve early patients' mobilization. To present, the effect of hip brace therapy on postoperative functional outcomes and specific patient individual psychologic factors remains controversially discussed. Consequently, we aimed to report postoperative outcomes focusing on hip function, pain and kinesiophobia between braced and unbraced patients. MATERIALS AND METHODS: A prospective, randomized-controlled trial was conducted, including patients undergoing hip arthroscopy for FAIS. After exclusion, a final study cohort of 36 patients in the intervention group (postoperative hip brace) and 36 patients in the control group (no hip brace) were compared for kinesiophobia (Tampa Scale of Kinesiophobia), pain (Visual analog scale) and joint function (International Hip Outcome Tool-12) within the first six postoperative months. RESULTS: Hip arthroscopy significantly improved all patient-reported outcomes in both groups. Intergroup analysis revealed significantly lower levels of kinesiophobia in braced patients at 6-months follow up (30.7 vs. 34.1, p = 0.04) while not negatively affecting pain and joint function. No intra- and postoperative complications occurred within both groups. CONCLUSIONS: This study could demonstrate that bracing after hip arthroscopy can positively influence kinesiophobia, while the brace did not negatively impact postoperative pain and quality of life. Thus, hip bracing could be a viable assistive therapy in the postoperative rehabilitation phase after hip arthroscopy.

Treating Spontaneous Pneumothorax Using an Innovative Surgical Technique Called Capnodissection Pleurectomy: Case Report.

Spontaneous pneumothorax is one of the most common conditions encountered in thoracic surgery. This condition can be treated conservatively or surgically based on indications and guidelines. Traditional surgical management includes pleurodesis (mechanical or chemical) in addition to bullectomy if the bullae can be identified. Mechanical pleurodesis is usually performed by surgical pleurectomy or pleural abrasion. In this case report, we present a case of a young patient with spontaneous pneumothorax who needed a surgical intervention. We performed a new, innovative surgical technique for surgical pleurectomy where we used carbon dioxide for dissection of the parietal pleura (capnodissection). This technique may provide similar efficiency to the traditional procedure but with less risk of bleeding and complications.

[Ischemic stroke due to paradoxical embolism through pulmonary arteriovenous malformation in a young patient]. / ACV isquémico debido a embolia paradojal a través de malformación arteriovenosa pulmonar en paciente joven.

Paradoxical embolism due to an isolated pulmonary arteriovenous malformation (PAVM) is a rare cause of ischemic stroke. PAVMs are abnormal high-flow connections between pulmonary arteries and veins, diverting deoxygenated blood into the systemic circulation and they represent a less common source of paradoxical embolisms, especially in young individuals. Endovascular embolization is the preferred treatment for clinically significant PAVMs. We present the case of a 34-year-old woman with a left thalamic ischemic stroke. Severe contrast passage was detected in cerebral arteries through transcranial Doppler. Intracardiac ultrasound did not reveal a patent foramen ovale, prompting further investigation with pulmonary CT angiography, confirming the presence of PAVM. The patient underwent successful endovascular treatment. It is essential to consider PAVM in the etiological diagnosis of ischemic stroke, especially in young patients with signs of abnormal right-to-left communication. Periodic follow-up imaging is recommended to assess potential recurrence or changes in PAVM, emphasizing the importance of appropriate management of these malformations.

La embolia paradojal debido a una malformación arteriovenosa pulmonar (MAVP) aislada es una causa infrecuente de accidente cerebrovascular (ACV) isquémico. Las MAVP son conductos anómalos de alta circulación entre arterias y venas pulmonares, desviando sangre desoxigenada hacia la circulación sistémica y representan una fuente menos común de embolias paradojales, especialmente en personas jóvenes. La embolización endovascular es el tratamiento preferido para MAVP clínicamente significativas. Presentamos el caso de una mujer de 34 años con ACV isquémico talámico izquierdo. Se detectó pasaje de burbujas "en cortina" en arterias cerebrales mediante Doppler transcraneal. En ecografía intracardíaca no se encontró foramen oval permeable, motivo por el cual se avanzó con realización de angiotomografía pulmonar, la cual confirmó la presencia de MAVP. La paciente recibió tratamiento endovascular exitoso. Es esencial considerar la MAVP en el diagnóstico etiológico del ACV isquémico, especialmente en pacientes jóvenes con signos de comunicación anormal de derecha a izquierda. Se recomienda un seguimiento periódico mediante imágenes para evaluar la posible recurrencia o cambios en la MAVP, resaltando la importancia del manejo adecuado de estas malformaciones.

Incidence and influencing factors of post-stroke cognitive impairment in convalescent young patients with first-ever stroke.

OBJECTIVE: To investigate the occurrence of post-stroke cognitive impairment (PSCI) and its influencing factors in convalescent young patients with first-ever stroke. METHODS: A total of 300 first-ever young stroke patients (age ≤45 years) were collected. The Mini-Mental State Examination (MMSE) was used to assess the cognitive status. The sociodemographic data, clinical symptoms, social environment, and behavior-related information were collected and analyzed. RESULTS: The incidence of PSCI in young stroke patients was 62.33 %. Through univariate analysis, there were statistical differences in different levels of education, smoking status and hypertension (P < 0.05). With subsequently multivariate logistic regression analysis, it was found that junior high school (OR=8.58,95 %CI:2.25∼32.70) and high school (OR=10.50,95 %CI:2.69∼41.00) education levels, lesion volume >3.00 cm3 (OR=8.03,95 %CI:2.28∼28.36), stroke in the frontal-parietal-temporal region (OR=7.26,95 %CI:1.58∼33.40) and the basal ganglia area (OR=6.13,95 %CI:1.24∼30.43), high NIHSS score (OR=1.17,95 %CI: 1.06∼1.29), and high diastolic blood pressure variability coefficient (OR=1.43,95 %CI: 1.02∼2.01) were risk factors for PSCI. Meanwhile, 24≤BMI<28 (OR=0.06,95 %CI:0.02∼0.23) and BMI<24 (OR=0.18,95 %CI:0.06∼0.53), hospitalization cost >20,000/month (OR=0.22,95 %CI:0.09∼0.56), and stroke onset in spring and summer (OR=0.37,95 %CI:0.14∼0.96) were protective factors. CONCLUSION: The incidence of PSCI is relatively high in young stroke patients. Junior high and high school education, stroke lesions >3.00cm3, strokes in the frontal-parietal-temporal and basal ganglia regions, high NIHSS scores, and high DBPV are risk factors for PSCI in young stroke patients. Meanwhile, BMI<28, treatment cost >20,000/month, and stroke onset in spring and summer are protective factors for PSCI in young stroke patients.

Non-stapling thoracoscopic surgery for spontaneous pneumothorax in young patients.

OBJECTIVES: Spontaneous pneumothorax in young patients has a high recurrence rate, even after surgical treatment, and bulla neogenesis around stapled lesions has been reported as a cause of postoperative recurrence. We investigate the clinical safety and long-term outcome of non-stapling thoracoscopic surgery for spontaneous pneumothorax in young patients. METHODS: Twenty-seven non-stapling thoracoscopic surgeries for pneumothorax in 24 patients younger than 25 years were retrospectively reviewed. The non-stapling surgical techniques used to treat bullae included thoracoscopic suture plication, soft-coagulation, covering, and ligation. Long-term follow-up was conducted by telephone or by a mailed questionnaire. RESULTS: In 22 (81.5%) operations, suture plication, soft-coagulation, and covering procedures were used in combination. The median number of bullae treated in one operation was 2 (range, 0-6). The median operative time was 97 min, and the median postoperative drainage and postoperative hospital stay periods were 1 and 3 days, respectively. No complications of grade 2 or higher were observed. Patients were followed for at least 30 (median, 37) months. The postoperative recurrence rate was 3.7%, with one case of recurrence due to bulla neogenesis at a distant site. CONCLUSION: Non-stapling thoracoscopic surgery with covering procedure for pneumothorax in young patients might reduce postoperative recurrence.

Cervical Pott's Disease Presenting As Quadriplegia in a Young Patient: A Case Report.

Cervical Pott's disease, a form of spinal tuberculosis (TB), is a significant concern in low- and middle-income countries (LMICs). Early detection and treatment are critical to preventing complications like vertebral collapse. Clinical and radiological features of cervical Pott's disease can resemble other spinal conditions, posing diagnostic challenges. We present a case of a 28-year-old female who initially presented with quadriplegia, cervical instability, and high-grade fever. Through multidisciplinary collaboration and prompt intervention, the patient was diagnosed with cord compression syndrome secondary to a cervical abscess and probable cervical Pott's disease. Anti-tuberculosis treatment (ATT) and steroids were initiated, leading to significant improvement in symptoms and disease resolution. In summary, this case underscores the diagnostic challenge of cervical Pott's disease and the importance of imaging in TB diagnosis in resource-limited settings. The positive treatment response emphasizes early intervention's significance.

High-risk human papillomavirus-associated corneal/conjunctival intraepithelial neoplasia in a young patient.

Purpose: To report a case of high-risk human papillomavirus (HPV)-associated corneal/conjunctival intraepithelial neoplasia (CIN) in a 17-year-old fair-skinned male with no other risk factors. Observations: A 17-year-old Caucasian male presented with an 18-month history of left eye pain, redness, itchiness, and decreased vision. Examination revealed a leukoplakic nasal limbal/peripheral corneal lesion resistant to topical antibiotic and anti-inflammatory treatments. Excisional biopsy confirmed the diagnosis of CIN, and RNA in situ hybridization testing for high-risk HPV types 16/18 was positive. Subsequent testing of the patient for human immunodeficiency virus (HIV) returned negative. Conclusions and Importance: The median age of CIN diagnosis in the United States is in the sixth decade of life and is usually associated with a history of ultraviolet (UV) light exposure. There are reports of CIN in young patients with systemic immunodeficiency, immunosuppression, xeroderma pigmentosum, atopic dermatitis, asthma, and vaping. Here we present a case of high-risk HPV-associated CIN in a young, fair-skinned patient with no other identifiable risk factors.

Surgical management of neck of femur fractures in patients younger than sixty-five years: a comparative study of three fixation methods.

PURPOSE: Several surgical implants have been used for the treatment of neck of femur fracture (NOF) in younger patients such as dynamic hip screw (DHS) and cannulated compression screw. However, the superiority of one or another osteosynthesis device remains a matter of debate. The aim of this work is to evaluate and compare three fixation modalities: Cannulated Hip Screws (CHS), DHS and DHS associated to anti-rotating screw for surgical treatment of femoral neck fracture in young adults. METHODS: It is a retrospective comparative study of three series of NOF fractures treated surgically over a period of ten years; including young adult patients (age > 18 years and < 65 years) treated conservatively using closed or open reduction and internal fixation. All types of NOF fractures according to Garden classification were included. Pathological, basi-cervical fractures and fractures on previously operated hips were excluded. The minimum follow-up recommended was two years. Clinical evaluation was based on the Postel Merle d'Aubigné score (PMA), the visual analogue scale (VAS), the Parker score, and the Hip Disability and Osteoarthritis Outcome Score (HOOS score). Reduction quality was assessed on X-rays. RESULTS: Our series included 72 patients that were divided in three groups: Group A: Fixation using cannulated hip screws (33 patients). Group B: Fixation using DHS only (21 patients). Group C: Fixation using DHS associated to anti-rotation screw (18 patients). The patients of group A had better PMA and VAS scores, but there was no statistically significant difference. However, a significant difference (p=0.001) was found for the HOOS score. The fractures treated with DHS associated with anti-rotating screws, had the highest loss of reduction in the vertical axis (Yp) with the highest femoral head collapse (Zp) values. Group A had the lowest loss of reduction in the horizontal axis (Xp). There was no significant difference between the three methods of osteosynthesis in terms of loss of correction though. CONCLUSION: We found comparable results in terms of healing and complication rates and loss of reduction for the three groups with no significant difference. However, the HOOS score was significantly better in the cannulated hip screw group.

Shoulder joint arthroplasty in young patients: Analysis of 8742 patients from the Australian Orthopaedic Association National Joint Replacement Registry.

Background: Shoulder replacement is a reliable treatment for the relief of pain and improvement of function in patients with glenohumeral arthritis, rotator cuff arthropathy, osteonecrosis and fracture. Limited data is available comparing revision rates for the different types of shoulder replacement when used in younger patients. This study aims to compare the survivorship of hemi resurfacing, stemmed hemiarthroplasty, total shoulder arthroplasty and reverse total shoulder arthroplasty in younger patients using data from a large national arthroplasty registry. Methods: Data from the Australian Orthopaedic Association National Joint Replacement Registry was obtained for the period 16 April 2004-31 December 2018. The study population included all shoulder arthroplasty patients aged <65 years. These were stratified into two groups: <55 years and 55-64 years. A total of 8742 primary shoulder arthroplasty procedures were analysed (1936 procedures in the <55 years and 6806 in the 55-64 years age group). Results: In the <55 years age group, there was no difference in revision rate for total shoulder arthroplasty versus reverse total shoulder arthroplasty at any time point. Reverse total shoulder arthroplasty had a lower revision rate after six months when compared to hemi resurfacing (HRA) (p = 0.031). Also, reverse total shoulder arthroplasty had a higher early rate of revision in the first 12 months compared to hemiarthroplasty (p = 0.018). However, from 2 years reverse total shoulder arthroplasty had a lower revision rate overall (p = 0.029).In the 55-64 years patient age group, reverse total shoulder arthroplasty had a lower earlier revision rate. This was statistically significant compared to hemi resurfacing (HRA) (p = 0.028), hemiarthroplasty (p = 0.049) and total shoulder arthroplasty (p < 0.001). Conclusion: This study demonstrated that for patients aged <55 years there was no significant difference in the rate of revision when total shoulder arthroplasty and reverse total shoulder arthroplasty were compared. reverse total shoulder arthroplasty had a lower rate of revision when compared to hemi resurfacing and hemiarthroplasty after 2 years. reverse total shoulder arthroplasty had the lowest comparative revision rate in patients aged 55-64 years overall.

Central retinal vein occlusion in young population: risk factors and outcomes.

Objective: To evaluate the risk factors and outcomes of central retinal vein occlusion (CRVO) in young patients (< 40 years). Methods: In this retrospective monocentric case series, we included young patients (<40 years) with CRVO. Patients' medical files were analyzed focusing on demographic characteristics, suspected risk factors, ophthalmic work-up, visual acuity (VA), treatment, and outcomes. Results: A total of 54 eyes of 52 patients were included. Central retinal vein occlusion was considered idiopathic in 13 patients (25%). The main risk factors identified were ocular hypertension (20.4%), inflammation (20.4%), high blood pressure (14.8%), and coagulation abnormality (11.1%). Final VA was lower in patients with high blood pressure and inflammation when compared to patients with no risk factor (p = 0.03 and 0.04, respectively). Intravitreal injections were needed in 23 eyes (42.6%) and 19 eyes (35.2%) received panretinal photocoagulation treatment. Conclusion: Central retinal vein occlusion is frequently associated with risk factors in young patients (75% of patients). In addition to the usual factors found in older patients, such as ocular hypertension and high blood pressure, coagulation abnormality and inflammation were also among the risk factors identified. Young patients with CRVO should be evaluated for the presence of risk factors and patients with high blood pressure or inflammatory findings should be followed carefully since they have a worse outcome.

Risk factors and survival prediction of young breast cancer patients with liver metastases: a population-based study.

Background: The risk and prognosis of young breast cancer (YBC) with liver metastases (YBCLM) remain unclear. Thus, this study aimed to determine the risk and prognostic factors in these patients and construct predictive nomogram models. Methods: This population-based retrospective study was conducted using data of YBCLM patients from the Surveillance, Epidemiology, and End Results database between 2010 and 2019. Multivariate logistic and Cox regression analyses were used to identify independent risk and prognostic factors, which were used to construct the diagnostic and prognostic nomograms. The concordance index (C-index), calibration plot, receiver operating characteristic (ROC) curve, and decision curve analysis (DCA) were used to assess the performances of the established nomogram models. Propensity score matching (PSM) analysis was used to balance the baseline characteristics between the YBCLM patients and non-young patients with BCLM when comparing overall survival (OS) and cancer-specific survival (CSS). Results: A total of 18,275 YBC were identified, of whom 400 had LM. T stage, N stage, molecular subtypes, and bone, lung, and brain metastases were independent risk factors for LM developing in YBC. The established diagnostic nomogram showed that bone metastases contributed the most risk of LM developing, with a C-index of 0.895 (95% confidence interval 0.877-0.913) for this nomogram model. YBCLM had better survival than non-young patients with BCLM in unmatched and matched cohorts after propensity score matching analysis. The multivariate Cox analysis demonstrated that molecular subtypes, surgery and bone, lung, and brain metastases were independently associated with OS and CSS, chemotherapy was an independent prognostic factor for OS, and marital status and T stage were independent prognostic factors for CSS. The C-indices for the OS- and CSS-specific nomograms were 0.728 (0.69-0.766) and 0.74 (0.696-0.778), respectively. The ROC analysis indicated that these models had excellent discriminatory power. The calibration curve also showed that the observed results were consistent with the predicted results. DCA showed that the developed nomogram models would be effective in clinical practice. Conclusion: The present study determined the risk and prognostic factors of YBCLM and further developed nomograms that can be used to effectively identify high-risk patients and predict survival outcomes.

Complex Primary Total Knee Arthroplasty in a Young Patient With Neurofibromatosis Type One and Multidirectional Knee Instability: Technical Tips and Outcome.

Neurofibromatosis is an inherited disorder that causes skin discoloration and tumors. The musculoskeletal symptoms are specific, including bone deformities, dysplasia, joint instability, and osteoporosis. We present a rare case of a young patient with neurofibromatosis and multidirectional knee instability who underwent a successful complex primary knee replacement surgery. Stress right knee radiographs showed global joint instability with permanent anterior knee dislocation, excessively hypoplastic femoral condyles and patella, joint surfaces incongruency, and hypoplastic varus tibia, with intraluminal midshaft bone bridge causing severe stenosis. The patient could not walk, had an unstable recurvatum right knee, and used a wheelchair for her professional activities. The surgery involved a fully cemented rotating-hinged total knee arthroplasty with tibial and femoral stems. After three years of follow-up, the patient remains pain-free, fully ambulatory with no walking aids, a stable knee, a full range of motion, and no signs of aseptic loosening. This case highlights the decision-making difficulties and the significant surgical challenges faced during the operation.

Tetralogy of Fallot Presenting with Superior Vena Cava Syndrome - A Rare Presentation.

Tetralogy of Fallot (TOF) presenting with superior vena cava (SVC) syndrome is an exceedingly rare scenario. The diagnosis of this condition is still a difficult task due to its unspecific clinical features and unclear recommendations for the best diagnostic tools. We report an interesting case of a 23-year-old male who was found to have TOF with the presentation of SVC syndrome after a sequential diagnosis. The timely diagnosis helped in the successful management of the patient. Through this case, we want to make clinicians aware of such a rare association and its diagnosis.

Intramedullary Tuberculoma of the Conus Medularis in an Immunocompetent Young Adult with no Pulmonary Tuberculosis, the Challenges of Diagnosis and Management: A Case Report and Review of Literature.

Background and Objective: Intramedullary tuberculoma (IMT) of the conus medullaris is an extremely rare tumour that constitutes a diagnostic and management challenge in a resource-limited setting. We report a case of conus medullaris, IMT in a young immunocompetent, patient with no prior clinical features of pulmonary or extra-pulmonary tuberculosis. Case Summary: The patient presented with six months history of progressive and persistent mid back pain and slight weakness of both lower limbs of 3 months duration. Physical examination revealed a well-nourished man with power of 3/5 and hyperreflexia on both lower limbs. Chest radiograph and other investigations for tuberculosis were negative. Magnetic resonance imaging (MRI) of the lumbosacral spine showed fusiform expansion of the conus medullaris, with a well circumscribed, ring enhancing, intramedullary mass straddle between T12 and L1. Patient had gross total resection with no intraoperative monitoring assistance and no post-operative worsening of neurological function. Histology showed granulomatous lesion with central caseation in keeping with a tuberculoma. Patient was commenced on post-operative anti-tuberculous therapy with physiotherapy, with full motor recovery at six months post-surgical intervention and anti-tuberculous therapy. Conclusion: Intramedullary tuberculoma can be considered as one of the differential diagnoses of intradural, intramedullary tumour of the conus, even in immunocompetent individual with no clinical features of tuberculosis.

Why and What Happens to Patients Younger Than 60 Years Who Need Revision Total Knee Arthroplasty?

BACKGROUND: With the increasing number of young patients undergoing primary total knee arthroplasty (TKA), there will be an increase in the number of patients who require revision. While the results of TKA in younger patients are well known, there is little information regarding to the outcomes of revision TKA in this population. The purpose of this study was to evaluate the clinical outcomes in patients <60 years of age undergoing aseptic revision TKA. METHODS: We retrospectively reviewed 433 patients undergoing aseptic revision TKA between 2008 and 2019. There were 189 patients <60 years compared to a group of 244 patients >60 years undergoing revision TKA for aseptic failures in terms of implant survivorships, complications, and clinical outcomes. Patients were followed for a mean of 48 months (range, 24 to 149). RESULTS: A total of 28 (14.8%) patients less than 60 years of age required repeat revision compared to 25 (10.2%) 60 years or older (odds ratio (OR) 1.94, 95% confidence interval (CI) 0.73-5.22, P = .187). There were no differences regarding postprocedural Patient-Reported Outcomes Measurement Information System (PROMIS) physical health scores (72.3 ± 13.7 versus 72.0 ± 12.0, P = .66) and PROMIS mental health scores (66.6 ± 17.4 versus 65.8. ± 14.7, P = .72), at an average of 32.9 and 30.7 months, respectively. Postoperative infection occurred in 3 (1.6%) patients <60 years of age, while 12 (4.9%) postoperative infections occurred in patients 60 years or older (OR 0.75, 95% CI 0.06-10.2, P = .83). CONCLUSION: There were no statistically significant differences in clinical outcomes between patients <60 versus > 60 years of age undergoing aseptic revision TKA.

[Cardiovascular diseases in the young patients : Place of the carotid intima-media thickness at the University Hospital-Ibn Rochd of Casablanca]. / Les maladies cardiovasculaires chez les jeunes patients : place de l'épaisseur intima-média carotidienne au CHU-Ibn Rochd de Casablanca.

BACKGROUND: The measurement of intima-media thickness (IMT), long neglected, is a fundamental element in the prediction of cardiovascular events. Vascular Doppler ultrasonography is one of the tools needed to objectify atherosclerosis. OBJECTIVES: The aim of our study is to establish a correlation between cardiovascular events and intima-media thickness. METHODS: We conducted a prospective, cross-sectional and descriptive study over a period of 6 months in the cardiology department of Chu-Ibn Rochd, based on vascular Doppler ultrasound data, presenting a risk factor and or vascular cardiovascular disease of the supra-aortic trunks using a high frequency linear probe (7.5 MHZ) connected to a GENERAL Electric ultrasound machine. Intima-media thickness was considered normal < 0.8 mm in adult patients aged 40-60 years. RESULTS: IMT ≥ 0.8 mm was found in 89.2% of patients out of a total of 102 patients recruited, predominantly male (54.9%) with a mean age of 56 ± 9 years. Cardiovascular risk factors and cardiovascular diseases were associated with an increase in IMT. Diabetics were the most frequent to have an elevated IMT, found at 50.9%, followed by 43.1% of hypertensives, 27.4% respectively between haemodialysis patients and ischemic strokes and 14% in coronary patients with indication of bypass surgery. CONCLUSIONS: Elevated IMT is associated with cardiovascular events and should be sought as their primary indicator in future large-scale studies so that it can be routinely assessed for a cardiovascular risk factor.

Driver and actionable mutations in younger patients with lung cancer - are we searching properly?

AIMS: The authors focused on a group of young lung cancer patients with the aim of better understanding the mechanisms of tumor pathogenesis in these patients and search for potential targetable mutations. METHODS: We collected retrospective data on patients under 40 years diagnosed with lung cancer (NSCLC or small-cell lung cancer) from 2011-2020 at the Department of Respiratory Diseases, University Hospital Brno, Czech Republic. Tumor tissue of these patients was analysed by next-generation sequencing (NGS, a panel of 550 variants in 19 genes). Demographic characteristics, smoking history, histology, molecular-genetic results and clinical stage of the disesase were recorded in all eligible patients from accessible medical databases. RESULTS: Of 17 identified patients in only 8 cases was successful NGS carried out due to lack of sufficient good quality material in the other cases. The most frequently found molecular genetic changes were EGFR, RICTOR and HER2 amplification and MET and FGFR1 amplification. In addition, we found rare pathogenic variants in BRAF and PIK3CA genes. Actionable variants were detected in 75% patients. CONCLUSION: We detected very frequent driver and potentially actionable alterations in young patients with lung cancer. This suggests different mechanisms of carcinogenesis in these patients and indicates that they might benefit more from a specific approach than older lung cancer patients.

Severe cervical kyphosis in a young adult with fixed dropped head syndrome, dysphagia, and myelopathy: A case report.

BACKGROUND: Several reports exist on syndromic cervical kyphosis in the elderly, including dropped head syndrome, degenerative spondylosis, and neurological diseases; however, it is rarely reported in young patients especially with complications. CASE PRESENTATION: We describe a case of a 25-year-old man who presented severe cervical kyphosis with dropped head syndrome, horizontal-gaze disorder, dysphagia, and myelopathy. The etiology of this cervical kyphosis was suspected to be as a result of a combination of an underlying developmental disorder and habitual, long-term cervical flexion postures while engaging in smartphone games. Combined anterior and posterior surgeries resulted in good outcomes and improved the patient's quality of life remarkably. CONCLUSION: Cervical kyphosis awareness in young patients is crucial. Moreover, combined anterior and posterior approach provides secure, good results, and with less sequelae.

Total Hip Arthroplasty in Patients Aged 40 to 60 Years Old: A Population-Based Study.

BACKGROUND: Contemporary total hip arthroplasty (THA) has resolved many implant longevity concerns in younger patients. Patients in their fourth and fifth decades of life are projected to be the fastest-growing demographic of THA patients. We aimed to assess this demographic to: 1) evaluate the rate of THA over time; 2) evaluate the cumulative incidence of revision; and 3) identify risk factors for revision. METHODS: A retrospective population-based study of patients between 40 and 60 years old undergoing primary THA was conducted using administrative data from a large clinical data repository. A total of 28,414 patients were included for analysis with a mean age of 53 years (range, 40-60 years) and median follow-up of 9 years (range, 0-17 years). Linear regressions were used to assess annual rates of THA in this cohort over time. Kaplan-Meier analysis was used to determine cumulative incidence of revision. Multivariate Cox proportional hazards models were used to determine association of variables with revision risk. RESULTS: The annual rate of THA in our population increased by 60.7% over the study period (P < .0001). Cumulative incidence of revision was 2.9% at 5 years and 4.8% at 10 years. Younger age, women, non-osteoarthritis diagnosis, medical complications, and annual surgeon volume ≤ 60 THA were associated with increased revision risk. CONCLUSION: Demand for THA continues to dramatically increase in this cohort. Risk of revision was low but multiple risk factors were identified. Future studies will help delineate the effect of these variables on revision risk and assess implant survivorship beyond 10 years.

Mean 16-Year Results of Total Hip Arthroplasty With Alumina Ceramic Femoral Heads on Highly Cross-Linked Polyethylene in Patients 50 Years or Less.

BACKGROUND: Highly cross-linked polyethylene (HXLPE) is a widely used bearing surface in total hip arthroplasty (THA); long-term results in young patients are limited. We previously demonstrated excellent results in HXPLE on cobalt-chrome femoral heads at 15-year mean follow-up. The purpose of the present study was to investigate polyethylene wear rates, implant survivorships, wear-related revisions, and patient-reported outcomes (PROs) in a young patient cohort who had alumina ceramic on HXPLE coupling at an average 16-year follow-up. METHODS: This was a retrospective study of 128 hips that underwent THA with HXLPE on alumina ceramic bearings between March 1, 2004, and April 15, 2007. The patient's mean age was 38 years (range, 13 to 50). All THAs utilized HXPLE liners with alumina ceramic heads. The University of California, Los Angeles activity score and modified Harris hip scores were collected preoperatively and at each follow-up. Martell hip analysis suite was used for wear calculations. RESULTS: At average 16 years (range, 13 to 18), aseptic revision survivorship was 93.3% and osteolysis/wear survivorship was 99.2%. The mean linear wear rate was 0.0191 mm/year and mean volumetric wear rate was 19.43 mm3/y, both of which were clinically undetectable. We observed excellent PROs with a significant increase in mean modified Harris hip scores (43.6 to 87.4, P < .0001) and the University of California, Los Angeles activity scores (4.0 to 6.0, P < .0001). There were no statistically significant differences in PROs or wear rates between ceramic and cobalt-chrome groups. CONCLUSION: At a mean 16-year follow-up, young patients who had HXLPE on ceramic coupling had excellent wear properties, PROs, and acceptable survivorships.
