Colonoscopy Utilization in Elderly Patients with Dementia: Characteristics, Complications, and Charges in a National Matched-Cohort Analysis.

BACKGROUND: It is projected that the elderly population will continue to increase. Many will develop chronic conditions such as dementia. AIMS: Our aims are to describe the utilization of colonoscopy among patients with dementia and compare outcomes in those with and without dementia. METHODS: This population-based analysis utilized the National Inpatient Sample (NIS) during 2019. Patients with dementia over the age of 60 years receiving colonoscopy were identified utilizing ICD-10 codes. Logistic regression was used for propensity score matching between the comparison groups. A Greedy one-to-one matching algorithm was utilized along with standardized mean differences to assess balance. Mcnemar test, signed rank sum, and paired t-test were used to compare the outcomes. RESULTS: Initially, 50,692 patients without dementia were compared with 4323 patients with dementia. Patients with dementia were more likely to be female, older, less likely White, had lower income, and more likely to be on Medicare. In the matched comparison (4176 in each group), complication analysis showed that patients with dementia did not have higher colonoscopy-related complications. They did have higher rates of other complications including renal/AKI (p = 0.0042), pulmonary/pneumonia (p = 0.003), cerebrovascular accidents (p = 0.0063), and sepsis (< 0.0001). Patients with dementia were also less likely to have routine discharges (< 0.0001), had longer hospital stays (< 0.0001), and higher hospital costs (< 0.0001). CONCLUSIONS: Elderly patients with dementia have similar colonoscopy-related complications as patients without dementia. However, they do have higher complications in general. The decision whether to perform colonoscopy in this patient population is multifactorial. A careful assessment of a dementia patient's history can help with this decision.

Trends in endovascular interventions for pediatric ischemic stroke at the national level: data from 2000 to 2009.

PURPOSE: Present knowledge is limited with regard to endovascular and interventional management of pediatric acute ischemic stroke (AIS). The current practice of neurointerventions in this population was analyzed via a national database. METHODS: The Kids' Inpatient Database for years 2000, 2003, 2006, and 2009 was examined for patients aged < 18 years discharged with a primary diagnosis of AIS and identified according to ICD-9 codes. Descriptive statistics were tabulated on each of the subcohorts. RESULTS: There were 3467 patients identified; 920 (26.5%) underwent angiograms, 51 (1.5%) angiogram + thrombolysis, and 18 (0.5%) received angiogram + endovascular recanalization. The angiogram only subcohort was significantly younger compared with thrombolysis and endovascular procedure subcohorts (9.8 vs. 12.2 vs. 14.9 years, P < 0.001). Mortality was 4.3%, significantly lower for angiogram only than for thrombolysis (1.1% vs. 18.2%, P < 0.0001). Thrombolysis also had significantly higher hospital charges ($149,045 vs. $64,826, P < 0.0001). While not many differences in outcomes between angiogram only versus endovascular procedures, the latter had higher financial burden ($122,482 vs. $64,826, P < 0.0001). CONCLUSIONS: This national study suggests that children receiving neurointerventions tend to be older (> 12 years) and heart and valvular defects are their most likely comorbidities. There was a lower mortality and fewer complications with endovascular procedures when compared with intravenous/intraarterial thrombolysis alone. Thrombolysis was also associated with more non-routine discharges and lengthier stay.

Pediatric spondylolysis/spinal stenosis and disc herniation: national trends in decompression and discectomy surgery evaluated through the Kids' Inpatient Database.

PURPOSE: The purpose of this study is to describe national trends in spinal decompression without fusion and discectomy procedures in the US pediatric inpatient population. METHODS: The Kids' Inpatient Database (KID) was queried for pediatric patients with primary diagnoses of spinal spondylolysis/stenosis or disc herniation and having undergone spinal decompression without fusion or discectomy over more than a decade (2000 to 2012). The primary (indirect) outcomes of interest were in-hospital complication rates, length of stay (LOS), total costs, and discharge dispositions. RESULTS: A total of 7315 patients, comprised of pediatric spinal spondylolysis/stenosis (n = 287, 3.92%) and pediatric disc herniation (n = 7028, 96.1%) patients, were included in the study. During the years 2000 to 2012, diagnoses of pediatric spondylolysis/spinal stenosis increased from 61 to 90 diagnoses per 3-year period, while diagnoses of pediatric disc herniation decreased from 2133 to 1335 diagnoses per 3-year period. Spinal decompression was associated with higher in-hospital complication rates (18.1 vs 5.3%, p < 0.0001), longer hospital stays (5 vs 1.69 days, p < 0.0001), higher mean total charges ($49,186 vs $19,057, p < 0.0001), and higher non-routine discharge rates (12.3 vs 2.5%, p < 0.0001) versus discectomy. CONCLUSIONS: Spinal decompression is associated with longer hospital stays, more complications, higher costs, and more non-routine discharges when compared to discectomy. The data supports the disparate nature of these disease processes and elucidates basic clinical trends in uncommon spinal disorders affecting children.

Treatment patterns of children with spine and spinal cord tumors: national outcomes and review of the literature.

BACKGROUND: Tumors of the spine in children are rare, and further clinical description is necessary. OBJECTIVE: This study investigated epidemiology, interventions, and outcomes of pediatric patients with spine and spinal cord tumors. METHODS: The National Inpatient Sample and Kids' Inpatient Database were used for the study. Outcomes were studied, and bivariate significant trends were analyzed in a multivariate setting. RESULTS: Analysis of 2870 patients between 2000 and 2009 found a median age of diagnosis of 11 years (Tables 1 and 2). Most were white (65.2%) and had private insurance (62.3%), and 46.8% of procedures were emergent operations. Treatment occurred at teaching (93.6%) and non-children's hospitals (81.1%). Overall mortality rate was 1.7%, non-routine discharges occurred at a rate 19.9%, complications at 21.1%, and average total charges were $66,087. A majority of patients (87.5%) had no intervention, and of those patients receiving treatment, 78.2% underwent surgery and 23.1% had radiotherapy. Treatment with surgery alone increased significantly over time (p < 0.0001). Odds ratio (OR) of mortality was significantly higher in 2006 (OR 3.5) and 2009 (OR 2.6) when compared to 2000. Complications (OR 7.9) and disease comorbidities (OR 1.5) were associated with significantly increased odds of mortality. CONCLUSIONS: Hospital characteristics, length of stay, and charges remained relatively unchanged. In recent years, there has been a decreasing incidence of spine and spinal cord tumors in children. Notably, a higher mortality rate is evident over time in addition to an increase in the proportion of patients undergoing surgery. The high percentage of emergent operations suggests a weak recognition of spine tumors in children and should prompt a call for increased awareness of this cancer. In spite of these findings, lack of tumor type identification was a limitation to this study.

National trends, complications, and hospital charges in pediatric patients with Chiari malformation type I treated with posterior fossa decompression with and without duraplasty.

BACKGROUND: The treatment of type 1 Chiari malformation (CM-1) with posterior fossa decompression without (PFD) or with duraplasty (PFDD) is controversial. The authors analyze both options in a national sample of pediatric patients. METHODS: Utilizing the Kids' Inpatient Database, CM-1 patients undergoing PFD or PFDD from 2000 through 2009 were analyzed. RESULTS: 1,593 patients with PFD and 1,056 with PFDD were evaluated. The average age was 10.3 years, slightly younger in PFD (9.8 vs. 10.9 years, p = 0.001). PFDD patients were more likely White (81.2 vs 75.6%, p = 0.04) and less likely admitted emergently (8.4 vs. 13.8%, p = 0.007). They also underwent more reoperations (2.1 vs. 0.7%, p = 0.01), had more procedure-related complications (2.3 vs. 0.8%, p = 0.003), a longer length of stay (4.4 vs. 3.8 days, p = 0.001) and higher charges (USD 35,321 vs. 31,483, p = 0.01). CONCLUSIONS: This large national study indicates that PFDD is performed more often in Caucasians, less so emergently, and associated with significantly more complications and immediate reoperations, while PFD is more frequent in those with syringomyelia and more economical, requiring fewer hospital resources. Overall, PFD is more favorable for CM-1, though it would be prudent to conduct a prospective trial, as this analysis is limited by data on preoperative presentations and long-term outcomes.

Clinical and radiographic outcomes of minimally invasive percutaneous pedicle screw placement with intraoperative CT (O-arm) image guidance navigation.

OBJECT: Intraoperative CT image-guided navigation (IGN) has been increasingly incorporated into minimally invasive spine surgery (MIS). The vast improvement in image resolution and virtual real-time images with CT-IGN has proven superiority over traditional fluoroscopic techniques. The authors describe their perioperative MIS technique using the O-arm with navigation, and they report their postoperative experience, accuracy results, and technical aspects. METHODS: A retrospective review of 48 consecutive adult patients undergoing minimally invasive percutaneous posterior spinal fusion with intraoperative CT-IGN between July 2010 and August 2013 at Cedars-Sinai Medical Center was performed. Two surgeons assessed 290 screws in a blinded fashion on intraoperative O-arm images and postoperative CT scans for bony pedicle wall breach. Grade 1 breach was defined to be < 2 mm, Grade 2 breach to be between 2 and 4 mm, and a Grade 3 breach to be > 4 mm. Additionally, anterior vertebral body breach was recorded. RESULTS: Of 290 pedicle screws placed, 280 (96.6%) were in an acceptable position without cortical wall or anterior breach. Of the 10 breaches (3.4%) 5 were lateral (50%), 4 were medial, and 1 was anterior; 90% of breaches were Grade 1-2 and all medial breaches were Grade 1. The one Grade 3 breach was lateral. No vascular or neurological complications were observed intraoperatively, and no significant postoperative complications were noted. The mean clinical follow-up period was 18 months (range 3-39 months). The overall clinical outcomes, measured using the visual analog scale (back pain scores), were improved significantly postoperatively at 3 months compared with preoperatively (visual analog score 6.35 vs 3.57; p < 0.0001). No revision surgery was performed for screw misplacement or neurological deterioration. CONCLUSIONS: New CT-IGN with the mobile O-arm scanner has increased the accuracy of pedicle screw/instrumentation placement using MIS techniques. The authors' high (96.6%) accuracy rate in MIS compares favorably with historical published accuracy rates for fluoroscopy-based techniques. Additional advantages of CT-IGN over fluoroscopic imaging methods are lower occupational radiation exposure for the surgical team, reduced need for postoperative imaging, and decreased rates of revision surgery. For now, the authors simply conclude that use of intraoperative CT-IGN is safe and accurate.

An institutional series and contemporary review of bacterial spinal epidural abscess: current status and future directions.

OBJECT: Over the past decade, the incidence of bacterial spinal epidural abscess (SEA) has been increasing. In recent years, studies on this condition have been rampant in the literature. The authors present an 11-year institutional experience with SEA patients. Additionally, through an analysis of the contemporary literature, they provide an update on the challenging and controversial nature of this increasingly encountered condition. METHODS: An electronic medical record database was used to retrospectively analyze patients admitted with SEA from January 2001 through February 2012. Presenting symptoms, concurrent conditions, microorganisms, diagnostic modalities, treatments, and outcomes were examined. For the literature search, PubMed was used as the search engine. Studies published from January 1, 2000, through December 31, 2013, were critically reviewed. Data from articles on methodology, demographics, treatments, and outcomes were recorded. RESULTS: A total of 106 patients with bacterial SEA were identified. The mean ± SD age of patients was 63.3 ± 13.7 years, and 65.1% of patients were male. Common presenting signs and symptoms were back pain (47.1%) and focal neurological deficits (47.1%). Over 75% of SEAs were in the thoracolumbar spine, and over 50% were ventral. Approximately 34% had an infectious origin. Concurrent conditions included diabetes mellitus (35.8%), vascular conditions (31.3%), and renal insufficiency/dialysis (30.2%). The most commonly isolated organism was Staphylococcus aureus (70.7%), followed by Streptococcus spp. (6.6%). Surgery along with antibiotics was the treatment for 63 (59.4%) patients. Surgery involved spinal fusion for 19 (30.2%), discectomy for 14 (22.2%), and corpectomy for 9 (14.3%). Outcomes were reported objectively; at a mean ± SD follow-up time of 8.4 ± 26 weeks (range 0-192 weeks), outcome was good for 60.7% of patients and poor for 39.3%. The literature search yielded 40 articles, and the authors discuss the result of these studies. CONCLUSIONS: Bacterial SEA is an ominous condition that calls for early recognition. Neurological status at the time of presentation is a key factor in decision making and patient outcome. In recent years, surgical treatment has been advocated for patients with neurological deficits and failed response to medical therapy. Surgery should be performed immediately and before 36-72 hours from onset of neurological sequelae. However, the decision between medical or surgical intervention entails individual patient considerations including age, concurrent conditions, and objective findings. An evidence-based algorithm for diagnosis and treatment is suggested.

Robotics and the spine: a review of current and ongoing applications.

OBJECT: Robotics in the operating room has shown great use and versatility in multiple surgical fields. Robot-assisted spine surgery has gained significant favor over its relatively short existence, due to its intuitive promise of higher surgical accuracy and better outcomes with fewer complications. Here, the authors analyze the existing literature on this growing technology in the era of minimally invasive spine surgery. METHODS: In an attempt to provide the most recent, up-to-date review of the current literature on robotic spine surgery, a search of the existing literature was conducted to obtain all relevant studies on robotics as it relates to its application in spine surgery and other interventions. RESULTS: In all, 45 articles were included in the analysis. The authors discuss the current status of this technology and its potential in multiple arenas of spinal interventions, mainly spine surgery and spine biomechanics testing. CONCLUSIONS: There are numerous potential advantages and limitations to robotic spine surgery, as suggested in published case reports and in retrospective and prospective studies. Randomized controlled trials are few in number and show conflicting results regarding accuracy. The present limitations may be surmountable with future technological improvements, greater surgeon experience, reduced cost, improved operating room dynamics, and more training of surgical team members. Given the promise of robotics for improvements in spine surgery and spine biomechanics testing, more studies are needed to further explore the applicability of this technology in the spinal operating room. Due to the significant cost of the robotic equipment, studies are needed to substantiate that the increased equipment costs will result in significant benefits that will justify the expense.

Instrumenting the small thoracic pedicle: the role of intraoperative computed tomography image-guided surgery.

OBJECT: Traditionally, instrumentation of thoracic pedicles has been more difficult because of their relatively smaller size. Thoracic pedicles are at risk for violation during surgical instrumentation, as is commonly seen in patients with scoliosis and in women. The laterally based "in-out-in" approach, which technically results in a lateral breach, is sometimes used in small pedicles to decrease the comparative risk of a medial breach with neurological involvement. In this study the authors evaluated the role of CT image-guided surgery in navigating screws in small thoracic pedicles. METHODS: Thoracic (T1-12) pedicle screw placements using the O-arm imaging system (Medtronic Inc.) were evaluated for accuracy with preoperative and postoperative CT. "Small" pedicles were defined as those ≤ 3 mm in the narrowest diameter orthogonal to the long axis of the pedicle on a trajectory entering the vertebral body on preinstrumentation CT. A subset of "very small" pedicles (≤ 2 mm in the narrowest diameter, 13 pedicles) was also analyzed. Screw accuracy was categorized as good (< 1 mm of pedicle breach in any direction or in-out-in screws), fair (1-3 mm of breach), or poor (> 3 mm of breach). RESULTS: Twenty-one consecutive patients (age range 32-71 years) had large (45 screws) and small (52 screws) thoracic pedicles. The median pedicle diameter was 2.5 mm (range 0.9-3 mm) for small and 3.9 mm (3.1-6.7 mm) for large pedicles. Computed tomography-guided surgical navigation led to accurate screw placement in both small (good 100%, fair 0%, poor 0%) and large (good 96.6%, fair 0%, poor 3.4%) pedicles. Good screw placement in very small or small pedicles occurred with an in-out-in trajectory more often than in large pedicles (large 6.8% vs small 36.5%, p < 0.0005; vs very small 69.2%, p < 0.0001). There were no medial breaches even though 75 of the 97 screws were placed in postmenopausal women, traditionally at higher risk for osteoporosis. CONCLUSIONS: Computed tomography-guided surgical navigation allows for safe, effective, and accurate instrumentation of small (≤ 3 mm) to very small (≤ 2 mm) thoracic pedicles.

Near-infrared imaging of brain tumors using the Tumor Paint BLZ-100 to achieve near-complete resection of brain tumors.

OBJECT: The intraoperative clear delineation between brain tumor and normal tissue in real time is required to ensure near-complete resection without damaging the nearby eloquent brain. Tumor Paint BLZ-100, a tumor ligand chlorotoxin (CTX) conjugated to indocyanine green (ICG), has shown potential to be a targeted contrast agent. There are many infrared imaging systems in use, but they are not optimized to the low concentration and amount of ICG. The authors present a novel proof-of-concept near-infrared (NIR) imaging system using a standard charge-coupled device (CCD) camera for visualizing low levels of ICG attached to the tumors. This system is small, inexpensive, and sensitive. The imaging system uses a narrow-band laser at 785 nm and a notch filter in front of the sensor at the band. The camera is a 2-CCD camera, which uses identical CCDs for both visible and NIR light. METHODS: The NIR system is tested with serial dilution of BLZ-100 from 1 µM to 50 pM in 5% Intralipid solution while the excitation energy is varied from 5 to 40 mW/cm(2). The analog gain of the CCD was changed from 0, 6, and 12 dB to determine the signal-to-noise ratio. In addition to the Intralipid solution, BLZ-100 was injected 48 hours before euthanizing the mice that were implanted with the human glioma cell line. The brain was removed and imaged using the NIR imaging system. RESULTS: The authors' results show that the NIR imaging system using a standard CCD is able to visualize the ICG down to 50 nM of concentration with a high signal-to-noise ratio. The preliminary experiment on human glioma implanted in mouse brains demonstrated that BLZ-100 has a high affinity for glioma compared with normal brain tissue. Additionally, the results show that NIR excitation is able to penetrate deeply and has a potential to visualize metastatic lesions that are separate from the main tumor. CONCLUSIONS: The authors have seen that BLZ-100 has a very high affinity toward human gliomas. They also describe a small, cost-effective, and sensitive NIR system for visualizing brain tumors tagged using BLZ-100. The authors hope that the use of BLZ-100 along with NIR imaging will be useful to delineate the brain tumors in real time and assist surgeons in near-complete tumor removal to increase survival and reduce neurological deficits.

COVID-19 and Its Sequelae Masquerading as Gastrointestinal Ailments: A Report of Gastroesophageal Reflux Disease (GERD) and Review of Recent Cases.

Coronavirus disease 2019 (COVID-19) predominantly causes respiratory symptoms. However, a rare segment of patients recovering from COVID-19 may develop gastrointestinal (GI) symptoms. We describe a case of a female who presented with symptoms suggestive of refractory gastroesophageal reflux disease (GERD) for 18 months following COVID-19 infection. Her symptoms included epigastric and chest pain, coughing, and vomiting. Upper endoscopy and 24-hour pH monitoring were negative. Following hospital admission due to worsening symptoms, she was diagnosed with chronic pulmonary embolism (PE) presumed to be related to COVID-19. Her reflux symptoms resolved within two days of the initiation of anticoagulation. Our findings suggest that chronic PE should be considered in patients presenting with GERD refractory to treatment following COVID-19 infection. Generally, as COVID-19 and its sequelae may masquerade as GI conditions, they should be on the differential diagnosis, especially in the post-pandemic era when routine testing has significantly declined.

SMARCA4-Deficient Undifferentiated Esophageal Carcinoma: A Clinical Case Series and Literature Review.

PURPOSE: Undifferentiated carcinoma of the esophagus (UEC) is a rare malignancy. Deficiency in SMARCA genes, critical for chromatin regulation, has been observed in cases of UEC. Research in UEC is sparse, however, and we present a case series along with a comprehensive review of the literature. CASE SERIES: Case 1 is a 49-year-old female with abdominal pain and dysphagia and esophagogastroduodenoscopy (EGD) showing a friable mass at the gastroesophageal (GE) junction. Biopsies showed a poorly differentiated neoplasm and immunohistochemistry showed loss for SMARCA4. With metastatic disease, she agreed to undergo palliative chemotherapy and radiation, passing away at 4 months. Case 2 is an 88-year-old male with dysphagia, nausea, vomiting, and distal esophageal mass with biopsy showing a malignancy with loss of SMARCA4 expression. Due to extensive metastases, he was counseled on hospice care. Case 3 is a 53-year-old male with extensive alcohol and smoking history presenting with hematemesis, passing away shortly. Posthumous histopathology consistent with undifferentiated SMARCA4-deficient carcinoma of the esophagus. Results of the literature review indicate a predilection towards males (75.0%) and a variable age range (39-88 years). Majority (76.2%) reported with a distal esophagus location. Metastatic disease was common at initial presentation. Median survival was 2.60 months. Some were managed with chemotherapy and radiation. CONCLUSIONS: Research in SMARCA-deficient UEC is very limited. It is more common in men, age is variable, and associated with Barret's esophagus. Further research is necessary to better understand it and to establish treatment guidelines; however, it is clear that SMARCA4-deficient UEC carries a significantly poor prognosis.

Positional plagiocephaly: an analysis of the literature on the effectiveness of current guidelines.

OBJECT: Positional plagiocephaly (PP) has been on the rise in recent years. In this review, the authors' aim was to assess the effectiveness of current recommendations to parents on this exceedingly common problem through a comprehensive literature search. Additionally, the current treatment options and the most recent studies on PP are reviewed. METHODS: A search of the existing literature was conducted to obtain all relevant studies on guidelines, recommendations, parental and clinician practices, and epidemiological aspects. RESULTS: Although the incidence and risk factors for PP have been well delineated, there continues to be debates on its management and association with developmental delays. Current guidelines and recommendations on prevention set by the American Association of Pediatrics may not be easily followed by both parents and clinicians. There is also evidence that certain populations, including those with lower education, socioeconomic status, and in particular geographic regions may be more affected by the condition. Additionally, the marketing and financial aspects of PP treatments exist and should be addressed. CONCLUSIONS: Better awareness and education are necessary to inform the population as a whole, although certain populations should be given special attention. Additionally, current guidelines and recommendations can be modified to foster a better grasp of the condition by both parents and clinicians. Adjusting current recommendations, introducing initiatives, and offering elaborate educational campaigns would help deliver these aims. Educating parents on PP as early as possible through clearer guidelines and close monitoring is central to preventing and managing this common condition.

Clostridium sordellii: A Cause of Toxic Shock Syndrome After a Breach in the GI Tract.

Clostridium sordellii is a highly virulent microorganism that causes serious infections, most commonly of the uterus and perineum. It has a high associated mortality rate due to the various toxins that it produces. A review of the literature suggests that knowledge surrounding its proper management is limited. This report describes a case of Clostridium sordellii causing toxic shock syndrome posttranslocation through the GI tract. A 69-year-old man with a past medical history of renal cell carcinoma and small bowl obstruction complicating transverse colostomy presented to the emergency room with back pain and rigors. Vital signs showed that he was in hemodynamic shock, and imaging revealed a left renal mass invading the adjacent splenic flexure of the colon. There was also a significant leukemoid reaction. After receiving a series of antibiotics, blood cultures revealed Clostridium sordellii as the pathogen of interest. As the first report of its kind, we identify a unique presentation of this organism, serving as a primary example of a different setting that clinicians should be aware of while at the same time highlighting a successful course of therapy for this often deadly organism.

AIDS-Related Kaposi Sarcoma Associated with Steroid-Unresponsive Periorbital Lymphedema that Responded to Chemotherapy.

BACKGROUND As an AIDS-defining illness, the neoplasm Kaposi sarcoma (KS) classically presents as cutaneous lesions that are often associated with periorbital edema. This association with KS is important because it frequently leads to the misuse of steroids in HIV-infected patients. This report presents 2 cases of AIDS-related Kaposi sarcoma (AIDS-KS) associated with severe steroid-unresponsive periorbital lymphedema that responded to chemotherapy. CASE REPORT Case 1: A 30-year-old African-American man with KS-related periorbital edema suffered progression after receiving multiple corticosteroids for a presumed hypersensitivity reaction. After multiple hospitalizations, the patient's KS had disseminated, and he eventually opted for hospice. Case 2: A 29-year-old White male with recurrent facial edema had been repeatedly treated with corticosteroids for impending anaphylaxis reactions. He had multiple admissions with similar presentations, and it was found that his KS had progressed. After receiving chemotherapy, his facial edema has not recurred. CONCLUSIONS The failure to recognize periorbital edema as tumor-associated edema has direct consequences for the management of AIDS-KS. In addition to a delay in administering chemotherapy, the mischaracterization of periorbital edema as a hypersensitivity/allergic reaction often prompts the use of corticosteroids, potentially exacerbating the underlying AIDS-KS. Despite the current evidence, clinicians continue to order steroids in advanced AIDS-KS patients presenting with periorbital edema. Although that management is started with the best intentions and done with concerns for airway compromise, this anchoring bias could lead to devastating consequences and a rather poor prognosis.

An Evaluation of Research Publications for General Surgery Residents And its Influence on the Future Pursuit of Fellowship or Academic Career.

INTRODUCTION: Traditionally, the Accreditation Council for Graduate Medical Education (ACGME) requires residency programs to implement research and other scholarly activities into their training curriculum. Encouraging residents to publish during residency is believed to promote research throughout their careers; however, the rate of research outcomes among general surgery residents remains unknown. Our study aims to determine associated factors that influence publication rates before, during, and after general surgery residency. METHODS: This observational study employed a cross-sectional design. We examined whether research outcomes during general surgery residency was associated with academic advancement or continued research involvement after residency. We identified 321 general surgery residency programs on the Doximity website and randomly selected 50 to include in our sample. Of these programs, graduate rosters for 31 programs were located and subsequently included. Of the 405 residency graduates identified, we recorded the number of peer-reviewed publications, H-indices, fellowships, and whether the graduate pursued a career in private practice or academia. RESULTS: Among the 405 physicians analyzed, 3815 total publications were identified with a mean of 9.4 (SD 11.8) per person. The most reported study design was observational studies (46.5%; 1775/3815) and the least reported was systematic reviews/meta-analyses (1.4%; 52/3815). The number of publications before residency positively correlated with having a higher h-index (r = 0.4). We also found that physicians who completed a fellowship had more publications during residency (mean = 4.7, SD = 6.5) than those not pursuing a fellowship (mean = 1.5, SD = 2.7; t= -4.3. p ≤ 0.001). We observed a statistically significant increase in the likelihood a physician pursued a career in academic medicine if they pursued a fellowship (OR: 3.77, 95% CI: 2.0-7.2) and if they had published research as a primary author (OR 1.25, 95% CI: 1.0-1.5). CONCLUSION: Increased research productivity was associated with continued academic pursuits and an increased likelihood of pursuing fellowship training after residency.

Status of Resident Attrition From Surgical Residency in the Past, Present, and Future Outlook.

OBJECTIVE: To investigate the current rate of attrition in general surgery residency, assess the risk factors, and identify prevention strategies. DESIGN: A literature review of the PubMed and MEDLINE databases, from January 1, 1980 to February 1, 2016, for relevant articles. The calculated attrition rate and the statistically significant influencing factors were the main measures and outcomes. SELECTION: All English language articles that described attrition from a general surgery residency were included. Articles that performed an assessment of attrition rates, academic performance, reasons for resident loss, and demographics were identified and data from these studies were collected. Random-effect meta-analysis and meta-regression based on a generalized mixed-effects model was performed. RESULTS: A total of 26 studies were included. Reported attrition rates ranged from 2% to 30% over the course of residency training. Random-effect meta-analysis is indicative of a yearly attrition rate of 2.4% (95% CI: 1.3%-3.5%) and a cumulative 5-year attrition rate of 12.9% (95% CI: 7.9%-17.8%). Most of them leave residency during their first 2 years, and the rate significantly decreases with increasing postgraduate year (p < 0.0001). The Accreditation Council for Graduate Medical Education mandated 80-hour week is associated with a higher rate, though not significantly (3.2% [95% CI: 1.3%-5.1%] vs. 2.2% [0.9%-3.5%], p = 0.37). Pooled analysis demonstrates no statistically significant difference in the rate of attrition between males and females (2.1% [95% CI: 1.1%-3%] vs. 2.9% [95% CI: 1.6%-4.1%], p = 0.73). Most remain in graduate medical education and pursue residency training in other specialties. CONCLUSION: Attrition in general surgery most commonly occurs within the first 2 years of training and, in contrast to previous findings, is not related to female sex. Restrictions on work hours seem to have increased the rate, whereas remediation practices can prevent it. Training programs should direct efforts towards attrition-prevention strategies.

Aspergillus spinal epidural abscess: case presentation and review of the literature.

STUDY DESIGN: In this review, we present a case of Aspergillus spinal epidural abscess (ASEA) and review the literature. OBJECTIVES: To provide further insight on a rare condition. SETTING: A description of a patient with ASEA in a 58-year-old woman that was successfully treated with conservative management is presented. METHODS: Following case presentation, a literature search (MedLine and PubMed) and assessment of epidemiology, presentation, diagnosis, treatments, and outcomes is performed. RESULTS: Review of the literature finds 26 reported cases. The infection occurs in males with a higher frequency (66.7%). The thoracic and lumbar regions are more likely afflicted (96.1%). Common symptoms are backache, neurological deficits, and fever. Most frequent comorbidities were malignancy, diabetes mellitus, and immunodeficiency. Complications were numerous and often catastrophic. Treatment entailed a combination of antibiotics and surgery. Overall, ASEA patients did poorly: death in majority (52%), minimal recovery in 22%, and others did attain full recovery (26%). CONCLUSIONS: Generally, this infection has high morbidity and mortality. Early identification is important to a successful outcome. Appropriate management with antifungals is central and proves to be effective as seen in the reported case though surgical intervention is usually a necessity as the literature suggests. From an epidemiological and public health perspective, particularly with recent outbreaks, understanding the treatment of this rare CNS infection becomes even more imperative.
