Perioperative Care for Children With Syndromic Craniofacial Synostosis Undergoing Le Fort III Surgery: A Retrospective Cohort Study.

To present characteristics, surgical variables, complications, and postoperative care in pediatric patients with craniofacial synostosis undergoing Le Fort III osteotomy. Craniofacial synostoses are a group of genetic syndromes that result in premature fusion of cranial and facial sutures, leading to craniofacial deformities and associated complications. Midface advancement through Le Fort III osteotomy is the most frequent surgical option for these conditions. Retrospective monocentric cohort study including patients with syndromic craniofacial synostosis who underwent Le Fort III osteotomy between 2009 and 2022 in a specialized referral center. Data collection encompassed surgical time, blood loss, intraoperative transfusions, fluid balance, and postoperative parameters such as duration of invasive mechanical ventilation and intensive care unit (ICU) length of stay. Twenty-six children were included in the analysis. The median surgical time was 345 minutes (300-360), with an estimated blood loss of 15 (9.9-24) mL/kg. Patients required a median transfusion of 12.63 (7.1-24.5) mL/kg of packed red blood cells and 19.82 (11.1-33) mL/kg of fresh frozen plasma. Intraoperative fluid balance was + 12.5 (0.8-22.8) mL/kg, with a median infusion of 30.4 (23.9-38.7) mL/kg of crystalloids. All patients were transferred to the ICU after surgery to ensure a safe environment for extubation. The median duration of mechanical ventilation in the ICU was 30 (20.25-45) hours, and postoperative ICU length of stay was 2 (2-4) days, and complications were infrequent, with only one extubation failure recorded. Le Fort III osteotomy in craniofacial synostosis patients may be characterized by a complex perioperative course. A multidisciplinary approach in the care of these patients allows for minimizing complications in the perioperative phase. Further research is needed to enhance perioperative management in this unique patient population.

Transitioning Towards a Virtual Falls Prevention Program for Frail Seniors: Learning from the Experiences of Older Adults During the COVID-19 Pandemic.

The literature to date is unable to clearly characterize the appropriateness of virtual care for falls prevention services from the patient perspective. In response to COVID-19, the Falls Prevention Program (FPP) at Sunnybrook Health Sciences Centre was modified to include virtual components. We set out to uncover the experiences of this unique older-adult patient population to inform FPP quality improvement and appropriate incorporation of technology post-pandemic. FPP patients during the COVID-19 pandemic (February 2020 - February 2022) and their primary caregivers met inclusion criteria. Out of 18 eligible patients, 10 consented to participate in 20-minute, semi-structured telephone interviews conducted and transcribed by the first author. Inductive coding followed by theme generation occurred through collaborative analysis. The participants (n=10) were 60% female, mean age 84 years (SD 5.8), 60% living alone, and 70% university educated. We generated three main themes: 1) First Steps First, revealed a common desire for physical and mental support and the perceived essentials of a successful FPP highlighting the importance of program length and individualized attention; 2) Overcoming Obstacles, highlighted participants' experiences overcoming barriers with technology in the context of an isolating pandemic; and 3) Advancing Care Post-Pandemic, elaborated on the appropriateness of virtual care and delved into the importance of program personalization. The interviewed older adults revealed agreement on the FPP's necessity and the importance of increasing program length, one-on-one interaction, and program flexibility for unique patient needs. Incorporating virtual assessment prior to in-person exercises was largely favoured and should be considered as an appropriate use of technology post-pandemic.

Mapping incidence and survival of non-small-cell lung cancers stratified by mutation type in southern Appalachia: A single center retrospective study.

e20568 Background: Non-small cell lung cancer (NSCLC) is often a mutation-driven disease with variability in incidence and survival depending on location as seen in population-based cohort studies. Our study aims to delineate these differences based on molecular testing for these mutations in our study cohort at East Tennessee State University - Quillen College of Medicine, which is based on patients from east Tennessee, western North Carolina, and southwestern Virginia. Methods: We obtained pathology results of 294 patient samples with advanced/metastatic NSCLC from our cancer center/health system database over a 5 year period. PDL-1 was tested in all patients. Fluorescent in-situ hybridization (FISH) testing for common pathogenic driver mutations such as EGFR, ALK, ROS1, RET, MET and PTEN were performed as is standard of care. Molecular sequencing was performed and included over 40 genetic mutations and 2 biomarkers, several of which today are considered targetable for advanced NSCLC, per standard of care. Incidence of different mutations was measured in our patient population. Overall survival was calculated with date of diagnosis available based on pathology report and date of patient expiration obtained from electronic medical records. Data analysis was performed to ascertain which mutations carried an increased risk of death. Results: The TP53 mutation was very common, seen in 85% of squamous cell carcinoma (SCC) histology and 55% of adenocarcinoma. Similarly, incidence of PTEN deletion by FISH was noted to be 52% in SCC and 31% in adenocarcinoma. EGFR mutations were rare, seen in only 3% of tested patients. We had an incidence of KRAS G12C mutations at 11% overall, but it was present in up to 18% of adenocarcinomas. BRAF was seen in 4.8% of all cases, 8% of adenocarcinomas and 2% of SCC. Since there were more than 2 predictors, Cox proportional-hazards regression model was fit. Due to either having all negative values or very few positive values, the variables CCND1, CDKN2B, ERBB2, ERBB4, FGFR, FGFR2, MET, MSI, NRAS, PDGFRA, RET, RS01, SCR were excluded from analysis. A total of 156 samples were used in final analysis. After model building, it was found that BRAF and KRAS G12C mutation were significant predictors of survival by hazard ratios for death. Conclusions: In our unique patient population, there was a greater incidence of deleterious TP53 mutations and PTEN deletions compared to the general North American advanced/metastatic NSCLC population. Although BRAF and KRAS G12C mutations were not at a greater incidence in comparison to the rest of North America, they were notably significant predictors of survival, conferring nearly 3.4 and 2.7 times increased risk of death in our study.

The impact of online CME on clinicians’ ability to utilize immunotherapy in unique populations of patients with NSCLC.

e21004 Background: Immunotherapy (IO) has become a standard of care in the management of advanced non-small cell lung cancer (NSCLC). However, treatment with IO-based regimens may not always be straightforward, particularly in unique clinical scenarios and patient populations. As such, members of the multidisciplinary care team, including oncologists and pulmonologists, may lack experience in utilizing IO in these instances. The objective of this study was to assess the educational impact of a series of continuing medical education (CME) activities on the knowledge, competence, and confidence of oncologists and pulmonologists with respect to recognizing strategies that facilitate the safe and effective use of IO in patients with advanced NSCLC. Methods: The educational analysis consisted of 2 online, CME-certified activities. Educational impact was assessed with repeated pre-/post-education including multiple choice knowledge/competence questions and 5-point Likert scale confidence questions. Data from all oncologists and pulmonologists who completed pre- and/or post-education assessments were aggregated across activities and stratified by learning theme. Relative changes in percentage of correct responses and clinicians who were confident (value of 4 or 5) were used to measure improvement in knowledge, competence, and confidence. A McNemar’s test assessed significant levels of changes reported with P values <.05 considered statistically significant. The first activity in the analysis launched October 2023 and the last launched November 2023; data were collected until January 2024. Results: The educational series resulted in improvements in oncologists’ (N=119) and pulmonologists’ (N=49) knowledge, competence, and confidence after education. Conclusions: This analysis demonstrates that oncologists’ and pulmonologists’ knowledge, competence, and confidence regarding the safe and effective use of IO in patients with advanced NSCLC improved after education. Despite these improvements, additional educational activities are needed to address residual gaps and further increase clinicians’ ability in these dynamic and challenging clinical settings.

Demographics and survival outcomes of stage IV male breast cancer: A retrospective analysis of SEER database.

11142 Background: Male Breast Cancer (MBC) is a rare malignancy accounting for <1% of all breast cancer cases in the United States. It is often lately diagnosed due to lack of awareness leading to substantial morbidity and mortality. Previous studies revealed higher risk of death among males compared to females across all stages, but little known about the impact of Hormone Receptor (HR) and Human Epidermal growth factor Receptor 2(HER 2) statuses on prognosis and survival among MBC patients. So, we aim to study the survival outcomes of stage IV MBC patients using SEER (Surveillance, Epidemiology, and End Results) data. Methods: A retrospective analysis was conducted using a SEER database and identified stage IV MBC cases (Any T, Any N, M1) diagnosed between 2010-2015. The selection of these years is based on the reporting of HER2 status on SEER database starting from 2010 and to ensure a current period and a minimum of 5 years of follow-up. Patient demographics, tumor HR/HER 2 status and survival data were extracted and analyzed. Subgroup analyses were performed to show the correlation between HR/HER 2 status and survival. Results: The study included 144 patients. 59.7%(86/144) were above 60 years of age. Majority were Caucasians up to 68.1%(98/144) followed by African Americans 18.7% (27/144), Hispanics 6.9%(10/144) and Asians/Pacific Islanders 6.2%(9/144). Among the subtypes, the most common was HR+/HER2- consisting of 69.4%(100/144) followed by HR+/HER2+ 19.4%(28/144), HR-/HER2- 9.7%(14/144), HR-/HER2+ 1.4%(2/144). The median overall survival varied among different subtypes of breast cancer and was noted to be 31.5 months, 25 months, 4.5 months and 10 months among HR+/HER2-, HR+/HER2+, HR-/HER2- and HR-/HER2+ respectively (Table). In the comparison between HR+/HER2+ and HR-/HER2-, the risk of death differed significantly, as indicated by a hazard ratio of 0.26 (95% CI 0.12-0.56, p = 0.001), highlighting a poor survival of HR-/HER2-. Conclusions: This retrospective analysis provides valuable insights into the demographics and survival outcomes of stage IV MBC patients. Triple negative (HR-/HER2-) subtype continues to have poor outcomes in males as well, emphasizing the need to explore novel treatment strategies to improve outcomes for this unique patient population. Although, treatment regimens for MBC are extrapolated from women, the disparity in survival across all subtypes requires the need to get more men on breast cancer clinical trials when feasible.

Renal disease associated with multiple sclerosis: A narrative review.

Multiple sclerosis (MS) is a chronic autoimmune neurological disorder characterized by central nervous system demyelination, leading to various neurological impairments. While the primary focus of research and clinical management has centered on the neurological aspects of MS, emerging evidence suggests a complex interplay between MS and renal disease. This narrative review endeavors to elucidate the intriguing association between MS and renal disease, providing a comprehensive overview of the current knowledge on this topic. Our review begins by outlining the pathophysiology of MS and the diverse mechanisms contributing to its progression. We then delve into renal disease, categorizing the various types and their clinical presentations. This review focuses on exploring the intricate relationship between these seemingly distinct conditions. We analyze existing literature to uncover shared risk factors, potential pathophysiological links, and the impact of MS on renal function. Furthermore, we discuss the clinical presentation and diagnostic challenges in identifying renal disease in MS patients. Importantly, we examine available treatment options and their efficacy in managing renal complications in this unique patient population. The consequences of renal disease on the overall quality of life (QOL) for individuals living with MS are also examined, shedding light on the multifaceted burden of these coexisting conditions.

Identifying risk factors for hypoxemia during emergence from anesthesia in patients undergoing robot-assisted laparoscopic radical prostatectomy.

Robot-assisted laparoscopic radical prostatectomy (RALP) has emerged as an effective treatment for prostate cancer with obvious advantages. This study aims to identify risk factors related to hypoxemia during the emergence from anesthesia in patients undergoing RALP. A cohort of 316 patients undergoing RALP was divided into two groups: the hypoxemia group (N = 134) and the non-hypoxemia group (N = 182), based on their postoperative oxygen fraction. Comprehensive data were collected from the hospital information system, including preoperative baseline parameters, intraoperative data, and postoperative recovery profiles. Risk factors were examined using multiple logistic regression analysis. The study showed that 38.9% of patients had low preoperative partial pressure of oxygen (PaO2) levels. Several clinical parameters showed significant differences between the hypoxemia group and the non-hypoxemia group, including weight (P < 0.0001), BMI (P < 0.0001), diabetes mellitus (P = 0.044), history of emphysema and pulmonary alveoli (P < 0.0001), low preoperative PaO2 (P < 0.0001), preoperative white blood cell count (P = 0.012), preoperative albumin (P = 0.048), intraoperative bleeding (P = 0.043), intraoperative CO2 accumulation (P = 0.001), duration of surgery (P = 0.046), postoperative hemoglobin level (P = 0.002), postoperative hypoxemia (P = 0.002), and early postoperative fever (P = 0.006). Multiple logistic regression analysis revealed BMI (adjusted odds ratio = 0.696, 95% confidence interval 0.612-0.719), low preoperative PaO2 (adjusted odds ratio = 9.119, 95% confidence interval 4.834-17.203), and history of emphysema and pulmonary alveoli (adjusted odds ratio = 2.804, 95% confidence interval 1.432-5.491) as independent factors significantly associated with hypoxemia on emergence from anesthesia in patients undergoing RALP. Our results demonstrate that BMI, lower preoperative PaO2, and a history of emphysema and pulmonary alveolar disease are independent risk factors associated with hypoxemia on emergence from anesthesia in patients undergoing RALP. These findings provide a theoretical framework for surgeons and anesthesiologists to facilitate strategies to mitigate postoperative hypoxemia in this unique patient population.

Meningioma: International Consortium on Meningiomas consensus review on scientific advances and treatment paradigms for clinicians, researchers, and patients.

Meningiomas are the most common primary intracranial tumors in adults and are increasing in incidence due to the aging population and increased access to neuroimaging. While most exhibit nonmalignant behavior, a subset of meningiomas are biologically aggressive and are associated with treatment resistance, resulting in significant neurologic morbidity and even mortality. In recent years, meaningful advances in our understanding of the biology of these tumors have led to the incorporation of molecular biomarkers into their grading and prognostication. However, unlike other central nervous system (CNS) tumors, a unified molecular taxonomy for meningiomas has not yet been established and remains an overarching goal of the Consortium to Inform Molecular and Practical Approaches to CNS Tumor Taxonomy-Not Official World Health Organization (cIMPACT-NOW) working group. Additionally, clinical equipoise still remains on how specific meningioma cases and patient populations should be optimally managed. To address these existing gaps, members of the International Consortium on Meningiomas including field-leading experts, have prepared this comprehensive consensus narrative review directed toward clinicians, researchers, and patients. Included in this manuscript are detailed overviews of proposed molecular classifications, novel biomarkers, contemporary treatment strategies, trials on systemic therapies, health-related quality-of-life studies, and management strategies for unique meningioma patient populations. In each section, we discuss the current state of knowledge as well as ongoing clinical and research challenges to road map future directions for further investigation.

Abstract PO3-09-12: Exploring Gender-Specific Patterns of Breast Cancer in Brazil: A Comparative Epidemiological Study

Abstract Introduction: Male breast cancer constitutes approximately 1% of all breast cancer cases, and limited studies have focused on this population, resulting in a lack of understanding of the disease in men. This study aims to describe the epidemiological profile of male breast cancer in Brazil and compare it with female breast cancer. Methods: A comprehensive observational cross-sectional study was conducted using retrospective data from the DATASUS database (SISCAN/Cancer Information System) spanning the period from 2017 to 2021. Male and female patients diagnosed with breast cancer (ICD C50) during this period were included. Statistical analysis involved absolute values, percentages, and a 95% confidence interval (p &amp;lt; 0.05). Results: Analysis of the study period revealed 4,326 cases (1.8%) of male breast cancer and 236,597 cases (98.2%) of female breast cancer in Brazil. The southeast region had the highest concentration of cases for both sexes, while the northeast region showed a higher prevalence in males (p &amp;lt; 0.0004). Noteworthy findings include a higher mean age among males (59.5 years) compared to females (55.7 years) and a higher prevalence of advanced stages at diagnosis in males (72.8% vs. 59.3%). Diagnostic approaches, subtype distribution, and treatment modalities also differed between the genders. Conclusions: Male breast cancer presents with more advanced stages at diagnosis compared to females, necessitating more aggressive surgical interventions. However, males benefit from earlier initiation of treatment. These findings contribute to a better understanding of male breast cancer, enabling the development of tailored management strategies for this unique patient population.

Development and Potential Implementation of Endometrial Cancer Screening in a Poor-Prognosis Endemic Cancer Community [ID 2683642

INTRODUCTION: Endometrial cancer incidence and mortality both are increasing in the United States. Certain patient populations are disproportionately affected by this disease. Currently, there is no recommendation from any professional society to screen high-risk patients for premalignancy or cancer. Our patient population is composed of predominantly Black women, a group that experiences worse endometrial cancer outcomes than other demographics. A risk assessment nomogram may be able to be developed using data from this unique patient population that can identify women at high risk of developing endometrial disease. METHODS: Endometrial pathology specimens collected at a large safety-net hospital between the years of 2013 and 2022 were analyzed. A retrospective chart review was performed on this data, looking for the patient characteristics of race, age, body mass index (BMI), parity, hemoglobin A1C level, and tamoxifen use history at the time of specimen collection. Odds ratios were calculated for those variables individually as well as collectively to determine whether they could be used to predict risk of endometrial disease in a woman with some of all those characteristics. RESULTS: The odds ratios for age, BMI, and parity were statistically significant between benign and abnormal pathologic specimens. The area under the receiver operating characteristic curve was 0.76 when combining age, BMI, and parity. CONCLUSION: Our data suggest that at-risk patients can be reliably identified using simple characteristics. Strengths of our study include a unique patient population and large database. Future directions include refinement of the model and prospective application in the clinical setting.

Esophageal Lichen Planus: A Descriptive Multicenter Report.

To better understand the characteristics, treatment approaches, and outcomes of patients with esophageal lichen planus (ELP). ELP is a rare, often unrecognized and misdiagnosed disorder. Data on this unique patient population are currently limited to small, single-center series. A multicenter, retrospective descriptive study was conducted of adults diagnosed with ELP over a 5-year period, between January 1, 2015, and October 10, 2020, from 7 centers across the United States. Seventy-eight patients (average age 65y, 86% female, 90% Caucasian) were included. Over half had at least 1 extraesophageal manifestation. Esophageal strictures (54%) and abnormal mucosa (50%) were frequent endoscopic findings, with the proximal esophagus the most common site of stricture. Approximately 20% had normal endoscopic findings. Topical steroids (64%) and/or proton pump inhibitors (74%) dominated management; endoscopic response favored steroids (43% vs. 29% respectively). Almost half of the patients required switching treatment modalities during the study period. Adjunctive therapies varied significantly between centers. Given its at times subtle clinical and endoscopic signs, a high index of suspicion and biopsy will improve ELP diagnosis, especially in those with extraesophageal manifestations. Effective therapies are lacking and vary significantly. Prospective investigations into optimal treatment regimens are necessary.

Multimodality Imaging of Postmastectomy Breast Reconstruction Techniques, Complications, and Tumor Recurrence.

For women undergoing mastectomy, breast reconstruction can be performed by using implants or autologous tissue flaps. Mastectomy options include skin- and nipple-sparing techniques. Implant-based reconstruction can be performed with saline or silicone implants. Various autologous pedicled or free tissue flap reconstruction methods based on different tissue donor sites are available. The aesthetic outcomes of implant- and flap-based reconstructions can be improved with oncoplastic surgery, including autologous fat graft placement and nipple-areolar complex reconstruction. The authors provide an update on recent advances in implant reconstruction techniques and contemporary expanded options for autologous tissue flap reconstruction as it relates to imaging modalities. As breast cancer screening is not routinely performed in this clinical setting, tumor recurrence after mastectomy and reconstruction is often detected by palpation at physical examination. Most local recurrences occur within the skin and subcutaneous tissue. Diagnostic breast imaging continues to have a critical role in confirmation of disease recurrence. Knowledge of the spectrum of benign and abnormal imaging appearances in the reconstructed breast is important for postoperative evaluation of patients, including recognition of early and late postsurgical complications and breast cancer recurrence. The authors provide an overview of multimodality imaging of the postmastectomy reconstructed breast, as well as an update on screening guidelines and recommendations for this unique patient population. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Soft Tissue Reconstruction After Sacral Neoplasm Resection: The University of California San Francisco Experience.

Resection of sacral neoplasms such as chordoma and chondrosarcoma with subsequent reconstruction of large soft tissue defects is a complex multidisciplinary process. Radiotherapy and prior abdominal surgery play a role in reconstructive planning; however, there is no consensus on how to maximize outcomes. In this study, we present our institution's experience with the reconstructive surgical management of this unique patient population. We conducted a retrospective review of patients who underwent reconstruction after resection of primary or recurrent pelvic chordoma or chondrosarcoma between 2002 and 2019. Surgical details, hospital stay, and postoperative outcomes were assessed. Patients were divided into 3 groups for comparison based on reconstruction technique: gluteal-based flaps, vertical rectus abdominus myocutaneous (VRAM) flaps, and locoregional fasciocutaneous flaps. Twenty-eight patients (17 males, 11 females), with mean age of 62 years (range, 34-86 years), were reviewed. Twenty-two patients (78.6%) received gluteal-based flaps, 3 patients (10.7%) received VRAM flaps, and 3 patients (10.7%) were reconstructed with locoregional fasciocutaneous flaps. Patients in the VRAM group were significantly more likely to have undergone total sacrectomy (P < 0.01) in a 2-stage operation (P < 0.01) compared with patients in the other 2 groups. Patients in the VRAM group also had a significantly greater average number of reoperations (2 ± 3.5, P = 0.04) and length of stay (29.7 ± 20.4 days, P = 0.01) compared with the 2 other groups. The overall minor and major wound complication rates were 17.9% and 42.9%, respectively, with 17.9% of patients experiencing at least 1 infection or seroma. There was no association between prior abdominal surgery, surgical stages, or radiation therapy and an increased risk of wound complications. Vertical rectus abdominus myocutaneous flaps are a more suitable option for patients with larger defects after total sacrectomy via 2-staged anteroposterior resections, whereas gluteal myocutaneous flaps are effective options for posterior-only resections. For patients with small- to moderate-sized defects, local fasciocutaneous flaps are a less invasive and effective option. Paraspinous flaps may be used in combination with other techniques to provide additional bulk and coverage for especially long postresection wounds. Furthermore, mesh is a useful adjunct for any reconstruction aimed at protecting against intra-abdominal complications.

Growth Factor in the Setting of CAR T-Cell Therapy: To Use or Not to Use

Patients undergoing chimeric antigen receptor (CAR) T-cell therapy may experience side effects including cytokine release syndrome (CRS), immune effector cell–associated neurotoxicity syndrome (ICANS), neutropenia, and infection. Growth factor has historically been used to treat neutropenia; however, its role in CAR T-cell therapy is not well explained. Existing data on the safety and efficacy of growth factor are conflicting. The purpose of this integrative review was to explore the safety and efficacy of growth factor in adult patients with hematologic malignancies undergoing CAR T-cell therapy. A literature review was conducted using PubMed, Cumulative Index to Nursing &amp; Allied Health (CINAHL), and Scopus databases. A total of 2,635 articles were retrieved. Four studies were included that looked at the use of growth factor in the CAR T-cell setting. Safety outcomes evaluated included CRS, ICANS, neutropenic fever and/or infection, and neutropenia duration. Efficacy outcomes evaluated included CAR T-cell expansion and treatment response. The literature suggests that growth factor may not increase CRS prevalence, but may lead to an increased grade of CRS, namely grade 2. Growth factor administration does not have any association with ICANS toxicity, CAR T-cell expansion, or treatment response. Its use may not necessarily lead to decreased infection rates but may shorten the duration of neutropenia. Practice implications for providers working with this unique patient population include using growth factor early in the course of CAR T-cell therapy as treatment to shorten the duration of neutropenia rather than infection prophylaxis.

Sacroiliitis in inflammatory bowel disease.

This review summarizes the recent evidence regarding the epidemiology of inflammatory bowel disease (IBD) associated sacroiliitis, including the prevalence, pathogenesis, role of imaging, and therapeutic challenges. Sacroiliitis is an underappreciated musculoskeletal manifestation of IBD, a chronic inflammatory condition of the gut affecting the younger population. Untreated sacroiliitis can lead to joint destruction and chronic pain, further adding to morbidity in IBD patients. Recent publications suggest sacroiliitis can be detected on abdominal imaging obtained in IBD patients to study bowel disease, but only a small fraction of these patients were seen by rheumatologists. Early detection of IBD-associated sacroiliitis could be achieved by utilization of clinical screening tools in IBD clinics, careful examination of existing computed tomography and MRI studies, and timely referral to rheumatologist for further evaluation and treatment. Current treatment approaches for IBD and sacroiliitis include several targeted biologic therapies, but IBD-associated sacroiliitis has limited options, as these therapies may not overlap in both conditions. With the advances in imaging, sacroiliitis is an increasingly recognized comorbidity in IBD patients. Future studies focusing on this unique patient population will expand our understanding of complex pathophysiology of IBD-associated sacroiliitis and lead to identification of novel targeted therapies for this condition.

Single-Stage Endoscopic Repair of Pediatric Basal Encephalocele: A Comprehensive Multimedia Case Report.

Basal encephaloceles are the result of a concomitant cranial and dural defect that allows for inferior displacement of cerebral tissue, meninges, and cerebrospinal fluid into the paranasal sinuses and outside the cranial vault. This work illustrates a step-by-step surgical approach of a successful single-stage, endoscopic repair of a congenital basal encephalocele in a 10-year-old child, using a free mucosal middle turbinate graft that provided effective results without utilization of traditional open reconstructive techniques or vascularized flaps. A previously healthy 10-year-old male with a history of unilateral clear rhinorrhea was admitted as an inpatient because of an acute episode of nausea, vomiting, and confusion, accompanied by fever, diplopia, and bilateral abducens nerve palsies. Preoperative imaging revealed a 2-cm right-sided intranasal mass accompanied by a subcentimeter skull base defect spanning the lateral lamella. After completing a course of intravenous antibiotic therapy for 1 week after a negative lumbar puncture to ensure clearance of intracranial infection, the decision was made to proceed with definitive endoscopic skull base repair to obviate recurrent bacterial meningitis episodes and potential neurological complications. This study demonstrates technical feasibility of a single-stage endoscopic endonasal approach for pediatric basal encephalocele resection and repair which minimizes craniofacial morbidity associated with traditional open approaches and sinonasal morbidity associated with local pedicle-based flaps for small cranial base defects in this unique patient population.

Ureteroscopy for urolithiasis in bedridden patients: it is feasible and acceptable.

To investigate the safety of transurethral ureteroscopy (URS) for urolithiasis in bedridden patients and to identify bedridden patient-specific risk factors for postoperative complications. The patients who underwent URS for urolithiasis were divided into bedridden patients and good performance status (PS) patients, and the groups were compared regarding their clinical characteristics and postoperative complications. A multivariable logistic regression analysis was performed to evaluate independent predictors of postoperative febrile urinary tract infection (fUTI). A total of 1626 patients were included, 276 in the bedridden patient group, and 1350 in the good PS patient group. The bedridden patient group had a significantly higher age and higher proportion of females and had multiple comorbidities. In 77 patients (27.9%), 88 postoperative complications developed for the bedridden patient group. Clavien-Dindo grade III or IV complications were observed in only 8 patients. No grade V complications were observed. The most common complication was fUTI. The frequency of fUTI with grade III or IV for the bedridden patient group (2.2%) was higher compared with the good PS patient group (0.5%), but the difference was not statistically significant (p = 0.13). Bedridden patient-specific risk factors for fUTI included female sex, diabetes mellitus, cerebrovascular comorbidities, lower extremity contracture, and prolonged operative time. URS for urolithiasis is a feasible and acceptable procedure in bedridden patients, despite the moderate rate of postoperative complications. The identified risk factors provide a framework for risk stratification and individualized care in this unique patient population.

Managing One-Lung Ventilation in Tracheostomized Patients: A 6-Year Retrospective Analysis

Abstract Background To ensure safe and optimal surgical conditions in thoracic surgery, one-lung ventilation is crucial. Various techniques exist to achieve one-lung ventilation. Tracheotomized patients who require one-lung ventilation represent a unique and rare subgroup that demands specialized knowledge and skills. The very limited literature has discussed alternative methods, no randomized controlled trials have addressed this issue yet. Methods We performed a retrospective analysis of patients who underwent one-lung ventilation in the Department of Thoracic Surgery of a German University Hospital between 2016 and 2021. The study assessed patient demographics, airway management techniques, ventilation parameters, and adverse events. Results In 3,197 anesthesia procedures during the observation period, 152 patients had an existing tracheostomy, of which 56 required one-lung ventilation. Among others in 42 cases, a tracheostomy tube was combined with a bronchial blocker, and in 10 cases, a double-lumen tracheostomy tube was used. There were no severe complications. Intraoperative dislocations that required repositioning of the device occurred in six patients (13.3%) with bronchial blockers and one patient with double-lumen tracheostomy tube (10%). Conclusion The management of one-lung ventilation in tracheotomized patients presents unique challenges. While double-lumen tracheostomy tubes have specific advantages, we recommend considering their use carefully. For most tracheotomized patients, bronchial blockers in conjunction with a tracheostomy tube are used, which offers safety and practicality, irrespective of the tracheostomy's age or type. Further research and randomized controlled trials are warranted to establish best practices for one-lung ventilation in this unique patient population.

Beyond Weight Loss: A Comprehensive Review of Pregnancy Management following Bariatric Procedures.

The increasing prevalence of bariatric surgery among women of childbearing age raises critical questions about the correct management of pregnancy following these procedures. This literature review delves into the multifaceted considerations surrounding pregnancy after bariatric surgery, with a particular focus on the importance of preconception counselling, appropriate nutrition assessment, and the necessity of correct folic acid supplementation. Key areas of investigation include nutrient absorption challenges, weight gain during pregnancy, and potential micronutrient deficiencies. Examining the relationship between bariatric surgery and birth defects, particularly heart and musculoskeletal issues, uncovers a twofold increase in risk for women who underwent surgery before pregnancy, with the risk emphasized before folic acid fortification. In contrast, a nationwide study suggests that infants born to mothers with bariatric surgery exhibit a reduced risk of major birth defects, potentially associated with improved glucose metabolism. In addition, this review outlines strategies for managing gestational diabetes and other pregnancy-related complications in individuals with a history of bariatric surgery. By synthesizing existing literature, this paper aims to provide healthcare providers with a comprehensive framework for the correct management of pregnancy in this unique patient population, promoting the health and well-being of both mother and child.

Bridging the gap: assessing CMV DNAemia in kidney transplant recipients with previous solid organ transplants.

Cytomegalovirus (CMV) infection poses a significant threat to solid organ transplant (SOT) recipients and can lead to various complications and adverse outcomes. In an effort to prevent CMV infection, it is common to utilize prophylactic strategies, including antiviral medications such as valganciclovir, especially for high-risk patients. Risk factors for CMV infection in kidney transplant recipients (KTRs) include CMV mismatch between donor and recipient (i.e., donor positive, recipient negative), and intensity of immunosuppression, such as the use of T-cell depleting agents. However, little attention has been given to KTRs with a history of prior SOTs, despite their prolonged exposure to immunosuppressive regimens. The aim of this retrospective single-center study was to investigate the incidence and implications of CMV DNAemia in KTRs with prior SOTs. The study included 97 KTRs with prior SOTs and 154 KTRs with no prior transplants as a control group. In the study group, the most common SOT before the current kidney transplantation (KT), was a previous KT. Patients in the KTR group with prior SOTs were more sensitized than those in the control group [calculated panel-reactive antibody > 30%: 49 (50.5%) vs. 30 (19.45%) patients, p = 0.001]. There was a 39.2% incidence of CMV DNAemia in the previous SOT group compared to 48.7% in the control group [non-significant (NS)]. Patients with prior SOTs demonstrated a shorter post-transplant time to CMV DNAemia [median time 1.6 months (interquartile range, IQR 0.7-5.8) in the KTRs with prior SOTs vs. 2.6 months (IQR 1.5-8.1) in the control group (p = 0.001)]. Although the study highlights the need for tailored prophylaxis strategies and vigilant monitoring in KTRs with prior SOTs, its limitations, such as its retrospective nature and single-center design, call for further multicenter research to establish comprehensive guidelines for managing CMV DNAemia in this unique patient population. Despite these limitations, this study underscores the importance of recognizing the heightened risk of CMV infection or reactivation in KTRs overall and the potential benefits of proactive intervention to mitigate associated morbidity and mortality.
