    BACKGROUND: Studying the differential impact of aspirin and other nonsteroidal anti-inflammatory drugs across the stages of colorectal neoplasia from early adenoma to cancer is critical for understanding the benefits of these widely used drugs. METHODS: With 13 years of follow-up, the authors prospectively evaluated the association between aspirin and ibuprofen use and incident distal adenoma (1221 cases), recurrent adenoma (862 cases), and incident colorectal cancer (CRC; 2826 cases) among men and women in the population-based Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. With multivariable-adjusted models, odds ratio (ORs) and 95% confidence intervals (CIs) for adenoma incidence and recurrence and hazard ratios (HRs) and 95% CIs for incident CRC were determined. RESULTS: The authors observed a significantly reduced risk of incident adenoma with ibuprofen use (≥30 vs \u3c4 pills per month: OR, 0.76 [95% CI, 0.60-0.95]; P(trend) = .04), particularly advanced adenoma (OR, 0.48 [95% CI, 0.28-0.83]; P(trend) = .005). Among those with a previous adenoma detected through screening, aspirin use was associated with a decreased risk of advanced recurrent adenoma (≥30 vs \u3c4 pills per month: OR, 0.56 [95% CI, 0.36-0.87]; P(trend) = 0.006). Both aspirin (HR, 0.88 [95% CI, 0.81-0.96]; P(trend) \u3c.0001) and ibuprofen use (HR, 0.81 [95% CI, 0.70-0.93); P(trend) = 0.003) ≥30 versus \u3c4 pills per month were significantly associated with reduced CRC risk. CONCLUSIONS: In this large prospective study with long-term follow-up, a beneficial role for not only aspirin, but also ibuprofen, in preventing advanced adenoma and curbing progression to recurrence and cancer among older adults was observed

    Autoimmune Hepatitis Disguised as Iron Overload Syndrome: Diagnostic Dilemma in a Nigerian Man

    Autoimmune hepatitis (AIH) is an extremely rare cause of chronic liver disease (CLD) in sub-Saharan Africa—there have only been 3 reported cases of AIH in Nigeria, a country of about 200 million people. We report the first case of AIH in a male patient in Nigeria and highlight its unusual presentation. A 41-year-old man with jaundice and malaise for 3 months was referred for evaluation after investigations revealed deranged liver enzymes and a cirrhotic liver. Laboratory evaluation revealed high serum immunoglobulin G, but there was also marked elevation of serum ferritin and transferrin saturation, resulting in a diagnostic dilemma between AIH and an iron overload condition such as hemochromatosis. A liver biopsy was crucial in providing a definitive diagnosis of AIH. Despite its rarity, clinicians should maintain a high index of suspicion for AIH in sub-Saharan Africa and should proceed to a liver biopsy when the cause of CLD is unclear

    Severe Hypercholesterolemia: A Unique Presentation of Non-Hodgkin’s Lymphoma in a Patient with Neurofibromatosis Type 1

    We report a case of non-Hodgkin’s lymphoma (NHL) with an unusual initial manifestation as severe hypercholesterolemia and obstructive jaundice in a patient with neurofibromatosis type 1 (NF 1). NHL should be considered in the evaluation of obstructive jaundice alone or in combination with severe hypercholesterolemia. Relief of biliary obstruction led to the resolution of hypercholesterolemia in our 59-year-old male patient, followed by doxorubicin-based chemotherapy for the underlying lymphoma. NF 1 is a genetic condition that results from a defect in a tumor-suppressor gene and it is likely that this led to the development of NHL in our patient. It is important that clinicians are familiar with the gastrointestinal manifestations of NF 1, especially its association with intra-abdominal malignancies, when treating patients with a personal or family history. To the best of our knowledge, this is the first case of NHL presenting initially as severe hypercholesterolemia and it is also one of the few instances where NHL has been reported in association with NF 1
