Gastrointestinal Variant of Lemierre Syndrome due to Fusobacterium nucleatum: A Case Report.

Introduction: Pyogenic liver abscess is a noteworthy health concern in North America, characterized by a mortality rate ranging from 2 to 12%. This condition is often polymicrobial, with Streptococcus species and Escherichia coli as the predominant causal pathogens in Western countries. Fusobacterium species, typically commensals of gastrointestinal, genital, and oral flora, have been implicated in the rare formation of tonsillar abscesses and Lemierre syndrome, including its gastrointestinal variant known as pylephlebitis. Case Presentation: We present the case of an immunocompetent male with a 2-week history of abdominal distention and pain. Abdominal magnetic resonance imaging revealed multiseptated cystic hepatic masses and portal vein thrombosis. A subsequent liver biopsy confirmed Fusobacterium nucleatum etiology. The patient was initiated on intravenous cefepime and oral metronidazole antibiotics. Unfortunately, the patient succumbed to cardiac arrest before a final diagnosis could be established. Conclusion: Fusobacterium species-associated liver abscess, coupled with the rare gastrointestinal variant of Lemierre syndrome (pylephlebitis), poses a significant mortality risk. This case underscores the rarity and clinical challenges associated with these conditions. Increased awareness among clinicians is crucial for early diagnosis and prompt intervention, potentially improving outcomes in such cases.

Taking a closer look into Crohn's disease and cerebral palsy.

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD), is a chronic, immune-mediated disease involving the gastrointestinal tract. Cerebral palsy (CP) has not been associated with IBD aside from a single previously published case series. In this study, we describe two cases of CD in patients with CP. Both patients had global developmental delay. They were also underweight and exclusively gastrostomy tube dependent for nutrition. By detailing their clinical courses, we illustrate the importance of becoming familiar with the extraintestinal manifestations of IBD. In the setting of developmental delay and its associated communication barriers, the evaluation of IBD might shift from assessing subjective symptoms to recognizing the subtle presentations of the disease, including anemia, weight loss, malnutrition, and failure to thrive. We also hypothesize that malnutrition and a change in the gastrointestinal microbiota associated exclusively with enteral nutrition may be linked to the development of CD in patients with CP. Overall, this study provides information for clinicians caring for patients with CP or developmental delay, and how to recognize extraintestinal manifestations of IBD.

National trends and outcomes of genetically inherited non-alcoholic chronic liver disease in the USA: estimates from the National Inpatient Sample (NIS) database.

BACKGROUND: Medical literature on the prevalence of genetic liver disease is lacking. In this study, we investigated the in-hospital healthcare and economic burden from genetic causes of non-alcoholic chronic liver disease (NACLD) and non-alcoholic liver cirrhosis (NALC) in the USA. METHODS: Data were abstracted from the National Inpatient Sample database between 2002 and 2014 using ICD9 codes for patients discharged with NACLD and NALC secondary to genetic diseases including alpha-1 antitrypsin deficiency (A1ATd), cystic fibrosis (CF), Wilson disease (WD), hereditary hemochromatosis (HHC), glycogen storage disease, and disorders of aromatic amino-acid metabolism (DAAAM). RESULTS: Throughout the study period, there were 19,332 discharges for NACLD associated with the six genetic diseases including 14,368 for NALC. There were $1.09 billion in hospital charges, 790 in-hospital deaths, and 955 liver transplants performed. Overall, A1ATd was associated with 8,983 (62.52%) hospitalizations for NALC followed by WD, CF, and HHC. The highest in-hospital mortality was seen with HHC. The greatest frequency of liver transplants was seen with DAAAM. CONCLUSION: The number of hospitalizations for genetic liver diseases continues to increase. With increased funding and directed research efforts, we can aim to improve medical treatments and the quality of life for patients at risk for liver deterioration.

Portal vein thrombosis as an initial presentation of Crohn's disease.

Inflammatory bowel diseases (IBD) are chronic and progressive conditions that can increase the risk of thromboembolism, including that of portal vein thrombosis (PVT). Overall, PVT is a serious complication with a significant associated mortality. PVTs are exclusively described in cases with confirmed IBD diagnosis. This report highlights a case of PVT as an initial manifestation of Crohn's disease.

National Trends and Outcomes of Nonautoimmune Hemolytic Anemia in Alcoholic Liver Disease: Analysis of the Nationwide Inpatient Sample.

GOAL: The aim of this study was to determine the burden of nonautoimmune hemolytic anemia (NAHA) in hospitalized patients with coexisting alcoholic liver disease (ALD), identify risk factors for NAHA in ALD and describe the hospitalization outcomes. BACKGROUND: ALD can result in structural and metabolic alterations in the red-blood cell membrane leading to premature destruction of erythrocytes and hemolytic anemia of varying severity. STUDY: Hospitalized ALD patients with concomitant NAHA were identified in the Nationwide Inpatient Sample database using International Classification of Diseases-9 codes from 2009 to 2014. The primary outcome was to determine the nationwide prevalence and risk factors of NAHA in patients hospitalized with ALD. RESULTS: The prevalence of NAHA was 0.17% (n=3585) among all ALD patients (n=2,125,311) that were hospitalized. Multivariate analysis indicated higher odds of NAHA in ALD patients in the following groups: female gender [adjusted odds ratio (AOR) AOR 1.80, P<0.0001]; highest quartile of median household income (AOR 1.88, P<0.0001); increasing Charlson-Deyo Comorbidity Index (3 to 4 vs. 0, AOR 2.16, P=0.0042) and cirrhosis (AOR 2.74, P<0.0001). Discharges of ALD with anemia had a significantly longer average length of stay (8.8 vs. 6.0 d, P<0.0001), increased hospital charges ($38,961 vs. $25,244, P<0.0001) and higher mortality (9.0% vs. 5.6%, P<0.0001) when compared with ALD with no anemia. CONCLUSION: NAHA in patients with ALD is an important prognostic marker, predicting a longer, costlier hospitalization and increased inpatient mortality in ALD.

A Case of Lethal Abdominal Compartment Syndrome due to Rapidly Expanding Ovarian Small Cell Carcinoma Pulmonary Type.

A 53-year-old woman presented with a rapidly growing pelvic mass suspected to be endometrial cancer due to endometrial biopsy showing grade 1 endometrioid adenocarcinoma. Due to severe aortic valve stenosis, she underwent a transcatheter aortic valve replacement (TAVR) for surgical optimization for a planned total abdominal hysterectomy, bilateral salpingo-oophorectomy, and tumor debulking. She was discharged on dual antiplatelet therapy with plans for future surgery, but was readmitted with abdominal distension, constipation, and urinary retention. The pelvic mass seen on prior imaging studies had increased in size. Unanticipated asystole cardiac arrest occurred two days after readmission, which on autopsy was found to be secondary to abdominal compartment syndrome from a rapidly enlarging ovarian small cell carcinoma pulmonary type.

A Rare Presentation of Non-Hodgkin's Lymphoma Presenting With Bleeding Esophageal Varices Secondary to a Malignant Portal Vein Tumor Thrombosis.

A 60-year-old woman presented with six months of abdominal pain, weight loss and diarrhea for which she underwent bidirectional endoscopies that were unremarkable. Over the next two weeks, she developed non-cirrhotic portal hypertension and presented with esophageal variceal bleeding. A diffuse large B-cell lymphoma encircling her celiac axis with a tumor thrombosis of the superior mesenteric, splenic and portal veins was found to be the cause of her portal hypertension. An esophagogastroduodenoscopy (EGD) was performed to control her variceal bleeding. She was started on R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) chemotherapy and after three cycles her symptoms have subsided, and a CT scan has shown shrinking mesenteric lymphadenopathy.

Hospitalizations for tuberculous peritonitis in the United States: Results from the national inpatient sample database from 2002 to 2014.

Background: Tuberculosis (TB) is an uncommon disease in the Western hemisphere that can present with peritoneal involvement, as tuberculous peritonitis(TBP) causing abdominal pain and fever. The healthcare and economic burden of TBP in the United States remains unknown. Methods: The National Inpatient Sample database was utilized to investigate TBP hospitalizations from 2002 to 2014. Economic expenditures, patient and hospital demographics, and associations of certain comorbidities with TBP were analyzed. Results: A total of 5878 hospitalizations for TBP occurred over the 12-year duration, with $420 million in-hospital charges. The median patient age was 45 years (interquartile range: 31.1-61.7), with the majority being Hispanic (27.15%). Hospitalizations occurred primarily in the Western (31.3%) and Southern (31.7%) United States. Patient comorbidities and the respective odds ratio associated with TBP included HIV (33.56), continuous peritoneal dialysis (10.49), malnutrition (7.38), liver cirrhosis (6.87), and liver cirrhosis sequelae (6.91). Nearly 6.37% of TBP hospitalizations also had active pulmonary TB. Conclusion: Although TBP is uncommon in the United States, it should be considered in patients presenting with abdominal pain and fever and a history of HIV, continuous peritoneal dialysis, malnutrition, liver cirrhosis, or liver cirrhosis sequelae.

Spontaneous fungal peritonitis: Micro-organisms, management and mortality in liver cirrhosis-A systematic review.

BACKGROUND: Spontaneous peritonitis is an infection of ascitic fluid without a known intra-abdominal source of infection. spontaneous fungal peritonitis (SFP) is a potentially fatal complication of decompensated cirrhosis, defined as fungal infection of ascitic fluid in the presence of ascitic neutrophil count of greater than 250 cells/mL. AIM: To determine the prevalence of fungal pathogens, management and outcomes (mortality) of SFP in critically ill cirrhotic patients. METHODS: Studies were identified using PubMed, EMBASE, Cochrane Central Register of Controlled Trials and Scopus databases until February 2019. Inclusion criteria included intervention trials and observation studies describing the association between SFP and cirrhosis. The primary outcome was in-hospital, 1-mo, and 6-mo mortality rates of SFP in cirrhotic patients. Secondary outcomes were fungal microorganisms identified and in hospital management by anti-fungal medications. The National Heart, Lung and Blood Institute quality assessment tools were used to assess internal validity and risk of bias for each included study. RESULTS: Six observational studies were included in this systematic review. The overall quality of included studies was good. A meta-analysis of results could not be performed because of differences in reporting of outcomes and heterogeneity of the included studies. There were 82 patients with SFP described across all the included studies. Candida species, predominantly Candida albicans was the fungal pathogen in majority of the cases (48%-81.8%) followed by Candida krusei (15%-25%) and Candida glabrata (6.66%-20%). Cryptococcus neoformans (53.3%) was the other major fungal pathogen. Antifungal therapy in SFP patients was utilized in 33.3% to 81.8% cases. The prevalence of in hospital mortality ranged from 33.3% to 100%, whereas 1-mo mortality ranged between 50% to 73.3%. CONCLUSION: This systematic review suggests that SFP in end stage liver disease patient is associated with high mortality both in the hospital and at 1-mo, and that antifungal therapy is currently underutilized.

Did we prioritize quality improvement in general surgery: Time for a focus on outcomes and enhanced recovery care plans?

BACKGROUND: In 2008, 2005-2006 National Surgical Quality Improvement Program (NSQIP) data were used to identify surgical operations contributing disproportionately to morbidity and mortality. Since then, numerous enhanced recovery programs have been utilized to augment quality improvement efforts. This study reassesses procedural complication incidence after a decade of quality improvement efforts. METHODS: Data from the 2015 NSQIP were used. The same original 36 general surgery procedure groups were created using Current Procedural Terminology codes. Ninety percent of our 409,230 patients matched into a procedure group and adverse event rates were analyzed for each. RESULTS: Ten procedure groups accounted for 80% of adverse events. Colectomy ranked the highest for adverse events (34%), readmissions (27%) and mortality rates (45.8%). For outpatient cholecystectomy, the relative percent point difference for adverse events has increased by 224% since 2005. CONCLUSION: Refocusing on colectomy and outpatient cholecystectomy represent current priorities in general surgery.

DRG migration: A novel measure of inefficient surgical care in a value-based world.

BACKGROUND: Diagnosis-Related Group (DRG) migration, DRG 331 to 330, is defined by the assignment to a higher cost DRG due only to post admission comorbidity or complications (CC). METHODS: We assessed the 5% national Medicare data set (2011-2014) for colectomy (DRG's 331/330), excluding present on admission CC's and selecting patients with one or more CC's post-admission to define the impact on payments, cost, and length of stay (LOS). RESULTS: The incidence of DRG migration was 14.2%. This was associated with statistically significant increases in payments, hospital cost, and LOS compared to DRG 331 patients. CONCLUSIONS: When DRG migration rate was extrapolated to the entire at risk population, the results were an increase of Centers for Medicare and Medicaid Services (CMS) cost by $98 million, hospital cost by $418 million, and excess hospital days equaling 68,669 days. These negative outcomes represent potentially unnecessary variations in the processes of care, and therefore a unique economic concept defining inefficient surgical care.

Outcomes of Laparoscopic Colectomy in Younger and Older Patients: An Analysis of Nationwide Readmission Database.

BACKGROUND: Prior studies report safety and effectiveness of laparoscopic colectomy in older patients. The study aimed to examine the impact of laparoscopic colectomy on 30-day readmissions, discharge destination, hospital length of stay, and cost in younger (19-65 years) and older adults (>65 years). MATERIALS AND METHODS: We used the nationwide readmission database from 2013 to study adults undergoing elective colectomy. The outcomes were 30-day readmissions, discharge destination for the index hospitalization (routine, skilled nursing facility [SNF]/intermediate care facility [ICF], home healthcare), length of stay, and cost. Multivariable analyses were conducted to determine the association of laparoscopic colectomy on outcome; logistic regression for 30-day readmission, multinomial logistic regression for discharge destination, and linear regression for length of stay and cost. An interaction between age and colectomy approach was included, and all models controlled gender, income, insurance status, All Patients Refined Diagnosis Related Groups (APR-DRG), Elixhauser comorbidities, hospital bed size, ownership, and teaching status. RESULTS: Of 79,581 colectomies, 40.2% were laparoscopic. Laparoscopic colectomy was more frequent in younger patients (41.9% versus 38.5%, p < .0001). Regardless of age, patients undergoing laparoscopic colectomy were 20% less likely to be readmitted within 30 days (odds ratio [OR] 0.80, confidence interval [95% CI] 0.75-0.85). For postdischarge destination, laparoscopic colectomy offered higher benefits to younger patients (SNF/ICF: OR 0.42, 95% CI 0.36-0.49; home health: OR 0.32, 95% CI 0.30-0.35) than older patients (SNF/ICF: OR 0.50, 95% CI 0.47-0.54; home health: OR 0.59, 95% CI 0.55-0.62). Regardless of age, laparoscopic colectomy resulted in 1.46 days (p < .0001) shorter hospital stays compared to open colectomy. Laparoscopic colectomy had significantly lower cost compared to open approach, particularly in younger ($1,466) versus older ($632) patients. CONCLUSIONS: Laparoscopic colectomy is superior to an open approach, with fewer 30-day readmissions, fewer discharges to SNF/ICF or home health, shorter hospital stays, and less overall cost; younger patients benefit more than older patients.

Computed tomography morphometric analysis of the central clival depression and petroclival angle for application of the presigmoid approach in the pediatric population.

AIMS: Lateral transtemporal approaches are useful for addressing lesions located ventral to the brainstem, especially when the pathologic diagnosis of the tumor dictates that a gross or near total resection improves outcomes. One approach, the presigmoid approach receives little attention in the pediatric population thus far. We sought to characterize morphometric changes, particularly the clival depth and the petroclival Cobb angle, that occur in the temporal bones of children and draw implications about doing a presigmoid approach in children. SETTINGS AND DESIGN: This study was a retrospective study performed at John Sealy Hospital, a level-one trauma center that takes care of pediatric injuries as well. SUBJECTS AND METHODS: We performed a morphometric analysis of noncontrast computed tomography head studies in 96 boys and 67 girls. Central clival depth and petroclival angle were obtained in the axial plane at the level of the internal auditory meatus using the method described by Abdel Aziz et al. STATISTICAL ANALYSIS USED: Descriptive statistics and Student's t-test to compare groups were calculated using Microsoft Excel. RESULTS: We found no gender difference in mean central clival depth or petroclival angle (P = 0.98 and P = 0.61, respectively). However, when we broke our cohort by age into those younger than 9 years of age and those 10 years or older, we found the petroclival angle decreased by 6.2° which was statistically significant (P < 0.000000006). CONCLUSIONS: These findings suggest that a presigmoid retrolabyrinthine approach is useful for children 9 years of age and younger as the petroclival angle appears to decrease resulting in a shallower clival depression in these patients.

Comparison of Comorbidity Scores in Predicting Surgical Outcomes.

INTRODUCTION: The optimal methodology for assessing comorbidity to predict various surgical outcomes such as mortality, readmissions, complications, and failure to rescue (FTR) using claims data has not been established. OBJECTIVE: Compare diagnosis-based and prescription-based comorbidity scores for predicting surgical outcomes. METHODS: We used 100% Texas Medicare data (2006-2011) and included patients undergoing coronary artery bypass grafting, pulmonary lobectomy, endovascular repair of abdominal aortic aneurysm, open repair of abdominal aortic aneurysm, colectomy, and hip replacement (N=39,616). The ability of diagnosis-based [Charlson comorbidity score, Elixhauser comorbidity score, Combined Comorbidity Score, Centers for Medicare and Medicaid Services-Hierarchical Condition Categories (CMS-HCC)] versus prescription-based Chronic disease score in predicting 30-day mortality, 1-year mortality, 30-day readmission, complications, and FTR were compared using c-statistics (c) and integrated discrimination improvement (IDI). RESULTS: The overall 30-day mortality was 5.8%, 1-year mortality was 17.7%, 30-day readmission was 14.1%, complication rate was 39.7%, and FTR was 14.5%. CMS-HCC performed the best in predicting surgical outcomes (30-d mortality, c=0.797, IDI=4.59%; 1-y mortality, c=0.798, IDI=9.60%; 30-d readmission, c=0.630, IDI=1.27%; complications, c=0.766, IDI=9.37%; FTR, c=0.811, IDI=5.24%) followed by Elixhauser comorbidity index/disease categories (30-d mortality, c=0.750, IDI=2.37%; 1-y mortality, c=0.755, IDI=5.82%; 30-d readmission, c=0.629, IDI=1.43%; complications, c=0.730, IDI=3.99%; FTR, c=0.749, IDI=2.17%). Addition of prescription-based scores to diagnosis-based scores did not improve performance. CONCLUSIONS: The CMS-HCC had superior performance in predicting surgical outcomes. Prescription-based scores, alone or in addition to diagnosis-based scores, were not better than any diagnosis-based scoring system.

Laparoscopy decreases complications for obese patients undergoing elective rectal surgery.

INTRODUCTION: While there are many reported advantages to laparoscopic surgery compared to open surgery, the impact of a laparoscopic approach on postoperative morbidity in obese patients undergoing rectal surgery has not been studied. Our goal was to determine whether obese patients undergoing laparoscopic rectal surgery experienced the same benefits as non-obese patients. METHODS: We identified patients undergoing rectal resections using the National Surgical Quality Improvement Project Participant Use Data File. We performed multivariable analyses to determine the independent association between laparoscopy and postoperative complications. RESULTS: A total of 26,437 patients underwent rectal resection. The mean age was 58.5 years, 32.6 % were obese, and 47.2 % had cancer. Laparoscopic procedures were slightly less common in obese patients compared to non-obese patients (36.0 vs. 38.2 %, p = 0.0006). In unadjusted analyses, complications were lower with the laparoscopic approach in both obese (18.9 vs. 32.4 %, p < 0.0001) and non-obese (15.6 vs. 25.3 %, p < 0.0001) patients. In a multivariable analysis controlling for potential confounders, the risk of postoperative complications increased as the degree of obesity worsened. The likelihood of experiencing a postoperative complication increased by 25, 45, and 75 % for obese class I, obese class II, and obese class III patients, respectively. A laparoscopic approach was associated with a 40 % decreased odds of a postoperative complication for all patients (OR 0.60, 95 % CI 0.56-0.64). CONCLUSION: Laparoscopic rectal surgery is associated with fewer complications when compared to open rectal surgery in both obese and non-obese patients. Obesity was an independent risk factor for postoperative complications. In appropriately selected patients, rectal surgery outcomes may be improved with a minimally invasive approach.
