Near obstructing painful anorectal mass and facial rash in a man with monkeypox: A case report.

BACKGROUND: Monkeypox (MPX) is a zoonotic infection that is endemic in Western and Central Africa along the Congo River basin. It has a high case fatality rate especially in younger age groups. It belongs to the virus family orthopoxvirus like smallpox. It is transmitted from wild animals to humans but human to human transmission has been established. It is often a self-limited infection in endemic regions. Recently, attention has been given to MPX with the spread of infection to Europe and the United States of America (USA). There is currently sporadic infection of MPX in the USA especially amongst men who have sex with men (MSM). It is a serious life-threatening infection in human immunodeficiency virus/acquired immunodeficiency syndrome co-infected individuals especially those who are treatment naïve with severe immunosuppression. CASE SUMMARY: We report a 38-year old man who presented with rectal pain, and anal, torso, and facial rash. Abdominal computed tomography scan showed a near obstructive rectal mass with peri-anal fistula. MPX was positive. He was started on tecovirimat (TPOXX) and HAART therapy. Additional treatment provided included vaccinia immunoglobulin following his clinical deterioration. CONCLUSION: This case highlights a rare presentation of MPX with peri-anal fistula and near obstructive rectal mass, and the significance of MPX as a differential diagnosis in proctitis in MSM in addition to other sexually transmitted infection like gonorrhea and chlamydia.

Utilization of access to colorectal cancer screening modalities in low-income populations after medicaid expansion.

BACKGROUND: Colorectal cancer (CRC) remains a relevant public health problem. Current research suggests that racial, economic and geographic disparities impact access. Despite the expansion of Medicaid eligibility as a key component of the Affordable Care Act (ACA), there is a dearth of information on the utilization of newly gained access to CRC screening by low-income individuals. This study investigates the impact of the ACA's Medicaid expansion on utilization of the various CRC screening modalities by low-income participants. Our working hypothesis is that Medicaid expansion will increase access and utilization of CRC screening by low-income participants. AIM: To investigate the impact of the Affordable Care Act and in particular the effect of Medicaid expansion on access and utilization of CRC screening modalities by Medicaid state expansion status across the United States. METHODS: This was a quasi-experimental study design using data from the Behavioral Risk Factor Surveillance System, a large health system survey for participants across the United States and with over 2.8 million responses. The period of the study was from 2011 to 2016 which was dichotomized as pre-ACA Medicaid expansion (2011-2013) and post-ACA Medicaid expansion (2014-2016). The change in utilization of access to CRC screening strategies between the expansion periods were analyzed as the dependent variables. Secondary analyses included stratification of the access by ethnicity/race, income, and education status. RESULTS: A greater increase in utilization of access to CRC screening was observed in Medicaid expansion states than in non-expansion states [+2.9%; 95% confidence interval (95%CI): 2.12, 3.69]. Low-income participants showed a +4.02% (95%CI: 2.96, 5.07) change between the expansion periods compared with higher income groups +3.19% (1.70, 4.67). Non-Hispanic Whites and Hispanics [+3.01% (95%CI: 2.16, 3.85) vs +5.51% (95%CI: 2.81, 8.20)] showed a statistically significant increase in utilization of access but not in Non-Hispanic Blacks, or Multiracial. There was an increase in utilization across all educational levels. This was significant among those who reported having a high school graduate degree or more +4.26 % (95%CI: 3.16, 5.35) compared to some high school or less +1.59% (95%CI: -1.37, 4.55). CONCLUSION: Medicaid expansion under the Affordable Care Act led to an overall increase in self-reported use of CRC screening tests by adults aged 50-64 years in the United States. This finding was consistent across all low-income populations, but not all races or levels of education.

Acute Hepatitis E Infection Associated With Deer Meat in the United States.

Acute hepatitis E virus (HEV) infection in the United States of America (U.S.A) is low. However, seroprevalence rate is about of 6%. Most cases of HEV infection have been reported from travelers from endemic countries with poor sanitary conditions. Evidence of HEV as a zoonotic infection has been reported from developed countries from swine and wild animals including boar and deer. There is no reported case of direct transmission from wild game to humans in the U.S.A. We report a case of HEV from butchering of deer meat.

Performance of Non-invasive Biomarkers of Liver Fibrosis Amongst Hispanics and African Americans.

INTRODUCTION:  Liver biopsy is the gold standard for fibrosis staging. However, it is limited by significant complications. Non-invasive markers of fibrosis have been developed as an alternative to liver biopsy. The performance of these different markers varies with the etiology of liver fibrosis and possibly amongst different ethnicities. We aim to assess the performance of non-invasive markers of liver fibrosis amongst Hispanics and African Americans. METHOD: This is a retrospective cohort analysis of patients who had liver biopsy as part of their evaluation of chronic liver disease. One hundred and twenty-six records were analyzed. Univariate and multivariate analyses were performed. Probit regression receiver operating characteristic curve analysis was used to assess the sensitivity of the different non-invasive biomarkers and underlying variables with respect to liver biopsy. The following non-invasive markers for fibrosis were used: Fibrosis-4 (FIB-4), aspartate aminotransferase (AST) to platelet ratio index (APRI), age-platelet, AST/alanine aminotransferase (AST/ALT) ratio, fibrosis cirrhosis index (FCI), and fibrosis index (FI). RESULTS: About two-thirds of the study population were African Americans with majority of the study population having chronic liver disease from viral infection. Minimal to no fibrosis by the METAVIR (an acronym for Meta-analysis of Histological Data in Viral Hepatitis) score was found in 58% of patients compared to 42% with moderate to severe fibrosis. Hispanics were more likely than Blacks to have hepatic steatosis. Age significantly increased the sensitivity and specificity of APRI and age-platelet scores. The AST/ALT score had a lower sensitivity for liver fibrosis in women compared to men in our study population. The sensitivity of FIB-4 and age-platelet was higher in Hispanics compared to African Americans while the opposite was the case for APRI, AST/ALT, FCI, and FI. CONCLUSION: Non-invasive biomarkers are useful in detecting liver fibrosis. FIB-4 and age-platelet have a high sensitivity in Hispanics while African Americans have a high sensitivity for APRI, AST/ALT, FCI, and FI. It is worth noting that these non-invasive biomarkers had variable performances when ethnicity, age, and sex were considered in our population.

Predicting Gastric Intestinal Metaplasia in a High-Risk Population.

INTRODUCTION: Gastric intestinal metaplasia (GIM) is a precancerous lesion. It has a low prevalence rate in the United States. However, GIM is more common among non-White and immigrant populations. Harlem Hospital serves a community that includes predominantly African Americans, Hispanics, and immigrants from West Africa and Spanish-speaking Caribbean countries. This study aims to define the factors predicting GIM in this high-risk group as well as help define screening strategies for vulnerable populations. METHODS: A total of 1351 patients who underwent endoscopic gastroduodenoscopy (EGD) and biopsy in 2018 and 2019 for any indication at Harlem Hospital were included in this study. Gastric biopsy specimens taken during the procedure were assessed for GIM by histopathology. Baseline demographics were collected, including age, sex, and ethnicity. Other information collected included risk factors for GIM such as Helicobacter pylori infection, smoking status, and the use of alcohol. Descriptive analysis was done and the Wilcoxon rank sum test and chi-squared test were used to test for associations. Multiple logistic regressions were used to assess the odds of independent factors associated with increased risk of GIM. RESULTS: Of the 1351 patients reviewed, 106 had GIM for a prevalence of 8.0% (CI: 6.7%-9.6%, p < 0.001). Univariate analysis revealed older patients, males, history of smoking, alcohol, and H. pylori infection were significantly associated with GIM. Using multiple logistic regressions and adjusting for underlying risk factors, smoking (OR: 1.61, 95% CI: 1.00-2.570) and H. pylori infection (OR: 3.35, 95% CI: 2.18-5.15) continued to be significantly associated with increased risk of GIM; however, alcohol use was not significant after adjusting for other risk factors (OR: 1.10, 95% CI: 0.68-1.78). Hispanic risk for GIM was slightly higher than African Americans (OR: 1.17, 95% CI: 0.74-1.83). The predicted marginal effect of age on the odds of GIM was significant from age 40 and increased exponentially at age 50. By age 70, the odds of GIM were as high as 11% (95% CI: 8.3-13.6). CONCLUSION: The prevalence of GIM in our population is significantly higher compared to reported cases in the United States. Age, male gender, H. pylori infection, and smoking significantly increase the risk of GIM. Given the high prevalence of GIM in our population, early endoscopic screening would play an important role in evaluating dyspepsia to diagnose GIM with or without H. pylori infection. We propose screening all at-risk ethnicities from age 40 years with EGD according to the Sydney System biopsy protocol. We believe this will ultimately decrease the incidence of gastric cancer death in these vulnerable populations of color.

Black voices in gastroenterology and hepatology.

The Association of Black Gastroenterologists and Hepatologists (ABGH) was established to improve health equity in Black communities and to provide academic and social support for Black gastroenterologists and hepatologists. In this Viewpoint, four members of ABGH (early career, mid-career and late career) discuss their route into gastroenterology and hepatology, how academia and medicine can promote inclusivity and equity, and their advice to Black students interested in a career in medicine or science.

Ischemic Gastropathy Treated with Celiac Artery Revascularization.

Ischemic gastropathy is an uncommon diagnosis due to extensive arterial collaterals that supply the stomach. The mucosal integrity of the stomach is dependent upon this redundant circulation. Hence, its diagnosis is infrequently entertained in patients presenting with an upper gastrointestinal (GI) bleed. Herein, we report a case of a 76-year-old woman with hypertension, hyperlipidemia, and chronic kidney disease on dialysis who developed an upper GI bleed after becoming septic and hypotensive.

A decade of improved access to screening is associated with fewer colorectal cancer deaths in African Americans: a single-center retrospective study.

BACKGROUND: Controversy exists as to whether disparities in colorectal cancer (CRC) outcomes in African Americans (AAs) are best resolved by screening at age 45 or by proper use of existing guidelines. In 2004, an aggressive colonoscopy-based CRC screening program was implemented throughout New York City. Our goal was to determine the effect of that program on CRC outcomes in our mostly AA population. METHODS: CRC cases entered into Harlem Hospital's tumor registry from January 1992 to December 2011 were divided into two cohorts: 1992-2003, the pre-intensive screening era (PSE), and 2004-2011, the intensive screening era (ISE). Each cohort was reviewed for demographics, indication for colonoscopy, tumor location, tumor stage, and mortality. Multivariate analysis was applied to the pooled cohorts to determine factors associated with survival. RESULTS: Inclusion criteria were met by 379 patients: 207 PSE and 172 ISE. Racial distribution, gender, age at presentation, and tumor location were not different during the two eras. Over 75% of patients were AA. During the ISE, 84% were insured compared to 34% in the PSE (P<0.0001). Fewer patients died during the ISE (21%) than during the PSE (67%) (P<0.0001). The ISE patients were diagnosed with earlier stages of CRC compared to the PSE. Increased survival was associated with being insured (hazard ratio [HR] 1.91, 95% confidence interval [CI] 1.30-2.81), distal tumors (HR 1.43, 95%CI 1.05-1.95), and being female (HR 1.36, 95%CI 1.01-1.850). CONCLUSIONS: A multifaceted program reduced CRC outcome disparities in a poor AA community. Aggressive implementation of current colonoscopy screening guidelines still has unrealized potential to reduce CRC mortality disparities in AAs.

A Novel Collaborative Community-Based Hepatitis B Screening and Linkage to Care Program for African Immigrants.

BACKGROUND: Sub-Saharan African nations have among the highest rates of chronic hepatitis B virus (HBV) infection worldwide, but little is known about HBV infection in African-born persons in the United States. METHODS: From October 2011 to July 2013, community-based HBV screenings were conducted targeting persons originating from Africa in New York City. Persons were identified as currently HBV infected (HBsAg positive) or exposed (HBcAb positive). RESULTS: Overall, 955 persons were screened for HBV; the median age was 45 years (interquartile range, 35-54 years) and 75.5% were men. Of these, 919 persons had no history of liver disease, of whom 9.6% (n = 88) had current HBV infection and 73.9% (n = 679) had exposure. In logistic regression, older age (odds ratio [OR], 0.97; 95% confidence interval [CI], .94-.99; P < .01) and female sex (OR, 0.35; 95% CI, .14-.75; P < .01) were less likely to be associated with HBV infection, whereas having a mother with hepatitis was associated with infection (OR, 18.8; 95% CI, 2.72-164.65; P < .01). HBV exposure was associated with older age (OR, 1.03; 95% CI, 1.01-1.04; P < .01), whereas female sex (OR, 0.46; 95% CI, .33-.66; P < .01) and history of blood transfusion (OR, 0.43; 95% CI, .22-.83; P = .01) were negatively associated. A patient navigator linked 97% of infected persons to care. Eleven persons were recommended for treatment, of whom 9 (82%) started therapy. Three persons were diagnosed with hepatocellular carcinoma on the first screening ultrasound. CONCLUSIONS: The high burden of HBV infection among African immigrants in the United States underscores a need for continued screening and linkage to care in this at-risk population.

Esophageal intramural pseudodiverticulosis, a rare cause of food impaction: case report and review of the literature.

Esophageal intramural pseudodiverticulosis (EIPD) is a rare, benign condition of uncertain etiology and pathogenesis, which usually presents with either progressive or intermittent dysphagia. Acute presentation with food impaction, requiring emergency esophago-gastroduodenoscopy (EGD), is rare. We report a case of EIPD presenting as food bolus impaction in an elderly black female. The patient had no previous history of dysphagia or odynophagia. Currently accepted risk factors, such as diabetes mellitus, chronic alcoholism, and reflux esophagitis, were not present in our patient. Emergency EGD established the diagnosis and also dislodged the food bolus. Histopathological evaluation of the mucosa diagnosed co-existent acute candidal infection. Medical treatment with proton pump inhibitor and azole antifungal led to resolution of her symptoms. Review of the literature revealed that stenosis, strictures, perforation, gastro-intestinal bleed, and fistula formation are potential complications of EIPD. Multiple motility abnormalities have been described but are not consistent. Treatment of the underlying inflammatory and or infectious condition is the mainstay of management of this unusual condition.

Spice/K2 synthetic marijuana-induced toxic hepatitis treated with N-acetylcysteine.

BACKGROUND: Spice/K2 is one of several street names for synthetic marijuana. These hallucinogens are increasingly sold over the internet and in "head" shops. They are usually household herbs that are sprayed with chemicals that become centrally active compounds when burned together and inhaled by smoking. CASE REPORT: We present a case of a 45-year-old male substance abuser who was admitted with evidence of hepatocellular necrosis and worsening liver failure. Tests for acetaminophen were negative, as were tests for alcohol. The patient was empirically treated with N-acetylcysteine. Hepatocellular damage was abated and the patient made a full recovery. Upon regaining consciousness, the patient admitted to smoking Spice/K2. Other toxicities have been reported with synthetic marijuana use, but not liver toxicity. CONCLUSIONS: Physicians need to have a high index of suspicion for unknown hepatotoxins in substance abusers. N-acetylcysteine can be given if there is no contraindication.

Case report of acute-on-chronic liver failure secondary to diffuse large B-cell lymphoma.

Acute liver failure is a rare presentation of hematologic malignancy. Acute on chronic liver failure (ACLF) is a newly recognized clinical entity that describes acute hepatic decompensation in persons with preexisting liver disease. Diffuse large B-cell lymphoma (DLBCL) is an aggressive non-Hodgkin's lymphoma (NHL) with increasing incidence in older males, females and blacks. However, it has not yet been reported, to present with acute liver failure in patients with preexisting chronic liver disease due to human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection. We describe a case of ACLF as the presenting manifestation of DLBCL in an elderly black man with HIV/HCV co-infection and prior Hodgkin's disease in remission for three years. The rapidly fatal outcome of this disease is highlighted as is the distinction of ACLF from decompensated cirrhosis. Due to the increased prevalence of HIV/HCV co-infection in the African American 1945 to 1965 birth cohort and the fact that both are risk factors for chronic liver disease and NHL we postulate that the incidence of NHL presenting as ACLF may increase.

Simultaneous diagnosis of cryptogenic organizing pneumonia and HIV in a 45 year old man.

BACKGROUND: Cryptogenic organizing pneumonia (COP) is a small airways disease characterized by intraluminal polyps of myxoid connective tissue which follows a subclinical course and is associated with infectious as well as non infectious processes The concomitant occurrence of human immunodeficiency virus (HIV) infection and COP has rarely been reported. We describe a unique case in which COP was a presenting feature in a patient with newly diagnosed HIV Infection. CASE REPORT: A 45 year-old man with chronic active smoking presented to the ER with 15 months history of cough productive of minimal whitish sputum without frank or streaks of blood, low grade fever, anorexia and 4-6 lbs weight loss in past 6 months. He had three life time sexual partners. PPD status were unknown. He was extensively worked up as the Chest X ray showed cystic lesions all of which came back normal. Patient also received HIV test which was positive with CD 4 count of 546. He received bronchoscopy which revealed cryptogenic organising pneumonia. He was placed on steroids tapering course which helped in relieving the symptoms. CONCLUSIONS: HIV infection with CD 4 count above 500 has seldom been reported having COP with this case being the second in literature but this entity should be kept in mind during management of these patients.

Role of interstitial cells of Cajal in motility disorders of the bowel.

OBJECTIVE: Idiopathic intestinal pseudo-obstruction is characterized by the failure of the intestinal tract to propel its contents appropriately. This leads to signs and symptoms of bowel obstruction and, in the absence of an associated systemic disorder or the administration of drugs known to result in bowel dysmotility, is termed chronic idiopathic intestinal pseudo-obstruction (CIIP). Histopathologically, patients with CIIP can be characterized as having either myopathic or neuropathic forms, but the large majority of patients do not show any specific histological changes. Interstitial cells of Cajal (ICC) have been shown to be the pacemaker cells of the bowel and have been implicated in the pathogenesis of CIIP. The aim of this study was to compare the number and distribution patterns of c-kit+ ICC in CIIP in patients with mechanical bowel obstruction, other bowel motility disorders, and normal controls. METHODS: Six patients with CIIP, six age-matched normal controls, nine patients with mechanical bowel obstruction, and 18 patients with other motility disorders (non-CIIP), including 10 with secondary intestinal pseudo-obstruction, were studied. Toluidine blue, Masson's trichrome, and S-100 immunostaining were performed in all subjects. The ICC were identified by an indirect immunoperoxidase method using a polyclonal c-kit antibody. RESULTS: All six patients with CIIP showed total absence of c-kit+ ICC. A subject with neonatal meconium ileus in the non-CIIP group showed patchy areas devoid of c-kit+ ICC amid normal areas. The c-kit+ ICC had a normal number and distribution pattern in all patients with mechanical obstruction and in the remaining 17 non-CIIP subjects. CONCLUSIONS: It seems that CIIP is characterized by a total loss of c-kit+ ICC. ICC may play an important role in the etiopathogenesis of CIIP and transient neonatal meconium syndrome, and staining for c-kit receptor may be very useful in the evaluation of motility disorders of the bowel.
