Prevalence of the cagA Virulence Factor Varies by Race Among Helicobacter pylori -Infected Patients Undergoing Upper Endoscopy.

INTRODUCTION: We designed a race-conscious study to assess the presence of Helicobacter pylori v irulence factor cagA in a retrospective cohort of patients with active H. pylori infection. METHODS: We compared cagA status by race in gastric tissue samples from 473 patients diagnosed with active H. pylori infection from 2015 to 2019. RESULTS: H. pylori + Black patients were 2 times more likely to be cagA + than H. pylori + White patients (82% vs 36%, P < .0001). DISCUSSION: Presence of cagA is common among endoscopy patients with active H. pylori infection; appropriate testing and treatment of H. pylori can both reduce gastric cancer risk and address health disparities.

Gastric Heterotopic Pancreas Presenting as Abdominal Pain with Acute and Chronic Pancreatitis in the Resected Specimen.

Heterotopic pancreas, also known as ectopic pancreas, is pancreatic tissue located outside the pancreatic parenchyma without vascular or ductal communication with the gland. Ectopic pancreas is rarely symptomatic, typically detected incidentally at surgery or autopsy. Eighty-five to 90% are in the upper GI tract, especially the gastric antrum. We report a 54-year-old man with symptomatic gastric heterotopic pancreas presenting as recurrent, initially undiagnosed, abdominal pain. Surgery revealed heterotopic pancreas including excretory ducts, acini, and islet cells. Evidence of acute pancreatitis was present, marked by inflammation and abscess formation. Chronic pancreatitis was diagnosed by fibrosis and dilated ducts containing proteinaceous material. Submucosal location with normal overlying mucosa on endoscopy increases risks of delayed or missed diagnosis. Complications include GI bleeding, acute or chronic pancreatitis, pancreatic necrosis, pseudocyst, gastric outlet obstruction, perforation, and, rarely, pancreatic carcinoma. This rare disorder mimics more common diseases. Low suspicion, nondiagnostic imaging or endoscopy contribute to frequent diagnostic delay.

A disease burden analysis of garment factory workers in Bangladesh: proposal for annual health screening.

Background: To characterize the health status of selected garment and textile factory workers in Bangladesh using a workplace mobile health clinic. Methods: A retrospective review of de-identified worker health information was performed using 1906 medical records. Results: The mean age of the workers was 27.9±7.3 y, with 60.3% (1150/1906) female and 39.7% (756/1906) male workers. The most common medical conditions identified were anemia (19.0%; 362/1906), elevated BP (EBP) (11.9%; 226/1906) and elevated fasting blood glucose (FBG) (8.0%; 151/1906). Among the workers who had EBP, 86.3% (195/226) were previously undiagnosed, while out of the workers with elevated FBG, 72.8% (110/151) were newly diagnosed. Men were more likely than women to have EBP (OR 3.5, 95% CI [2.12-5.56], p<0.001), a family history of diabetes (OR 3.6, 95% CI [2.1-5.9], p<0.001) and no formal education (OR 4.9, 95% CI [3.6-6.7], p<0.001). Conclusions: Despite the relatively young mean age, significant percentages of workers were identified as having undiagnosed chronic health conditions, including EBP and elevated FBG, that require urgent medical attention and health education. The findings suggest that provision for annual health screening, either by mobile on-site clinics or by training the existing in-house paramedics, will help improve health of the factory workers.

Hypersensitivity to Orthopedic Implants: A Review of the Literature.

Awareness of rare etiologies for implant failure is becoming increasingly important. In addition to the overall increase in joint arthroplasties, revision surgeries are projected to increase dramatically in the coming years, with volume increasing up to seven-fold between 2005 and 2030. The literature regarding the relationship between metal allergy and implant failure is controversial. It has proven difficult to determine whether sensitization is a cause or a consequence of implant failure. Testing patients with functional implants is not a clinically useful approach, as the rate of hypersensitivity is higher in implant recipients than in the general population, regardless of the status of the implant. As a result of the ineffectiveness of preoperative patch testing for predicting adverse outcomes, as well as the high cost of implementing such patch testing as standard procedure, most orthopedists and dermatologists agree that an alternative prosthesis should only be considered for patients with a history of allergy to a metal in the standard implant. In patients with a failed implant requiring revision surgery, hypersensitivity to an implant component should be considered in the differential diagnosis. Because a metal allergy to implant components is currently not commonly considered in the differential for joint failure in the orthopedic literature, there should be improved communication and collaboration between orthopedists and dermatologists when evaluating joint replacement patients with a presentation suggestive of allergy.

Orthopedic Manifestations of Ochronosis: Pathophysiology, Presentation, Diagnosis, and Management.

Ochronotic arthropathy occurs in patients with alkaptonuria, manifesting first in the intervertebral discs of the lumbar spine, with subsequent degeneration most often observed in the knee, hip, and shoulder joints. Efforts at treatment are targeted at minimizing the damaging effects of the underlying metabolic disorder on the articular cartilage. Vitamin E and N-acetyl cysteine are potential therapies because of their scavenging of free radicals and consequent limitation of oxidative damage to joint tissue. Arthroscopy has been found to be an effective diagnostic tool in cases of suspected ochronosis. Arthroplasty performed in patients with ochronotic arthropathy suggests that the procedure is effective in the alleviation of joint pain and the improvement of mobility. Perioperative management of these patients may require more careful consideration pertinent to the associated comorbidities of this disorder.
