RESUMEN
Biliary tract cancers, including cholangiocarcinoma, gallbladder, and ampulla of Vater cancers, rank second among hepatobiliary cancers, known for their poor prognoses. The United States has witnessed a notable increase in intrahepatic cholangiocarcinoma incidence. This study examines the incidence and survival outcomes of biliary tract cancers in Olmsted County, Minnesota from 1976 to 2018. Using data from the Rochester Epidemiology Project (REP), residents aged 20 and above were analyzed across four eras. Incidence rates were calculated and adjusted for age and sex, and temporal trends were assessed using Poisson regression. Intrahepatic cholangiocarcinoma exhibited a significant escalation in incidence rates over time, while gallbladder cancers showed a decline among women. Median survival times for biliary tract cancers notably improved. These findings confirm the rising incidence of intrahepatic cholangiocarcinoma and suggest improving survival rates. Nevertheless, the overall prognosis for biliary tract cancers remains very poor, emphasizing the continual need for enhanced management strategies and further research.
RESUMEN
Primary hepatic leiomyomas are rare tumors most commonly in immunosuppressed individuals who are coinfected with Epstein-Barr virus (EBV). From our literature review, there have been 50 published cases, of which 24 were immunocompetent individuals and only 5 were negative for EBV infection. We report a case of primary hepatic leiomyomas in an asymptomatic middle-aged woman without a history of immunosuppression or EBV infection.
RESUMEN
Segmental colitis associated with diverticulosis (SCAD) is an inflammatory disease affecting segments of the large bowel with diverticular disease. SCAD presents several challenges in diagnoses and treatment because it often mimics a range of disorders including inflammatory bowel disease and malignancy. Here, we present the case of a 72-year-old man with lower abdominal pain and bloody stools whose initial abdominal workup showed nonspecific large bowel thickening and concerns for malignancy. Ultimately, the patient was diagnosed with mild SCAD and treated conservatively with a resolution of symptoms. He had no symptoms at the three-month and 1-year follow-ups. This case highlights the importance of including SCAD in the initial differential diagnosis to allow accurate identification and treatment.
RESUMEN
BACKGROUND: Colorectal cancer (CRC) is the second-leading cause of death in the USA. CRC screening remains underutilized, especially in underinsured populations. Screening has been heavily disrupted during the COVID-19 pandemic. PURPOSE: The goal is to explore the impact of the pandemic on ethnic and gender disparities in CRC screening. METHODS: Patients were identified 1 year before and after COVID-19 precautions began, using March 1, 2020, as the inflection point. The primary inclusion criterion was an ordered colonoscopy. The outcome of interest was a colonoscopy performed. Differences by year and race were assessed using chi-square analysis. A cohort of 1549 patients (899 in pre-COVID; 650 in post-COVID) between age 45 and 75 for whom a colonoscopy was ordered was selected from EHR at a large institution. RESULTS: There was a 51% reduction in screening colonoscopies performed. White patients had a decrease of 49%, and African Americans had a 55% reduction. Stool testing increased from 47% prior to the pandemic to 94% during the pandemic representing a greater than 100% increase in stool testing uptake. CONCLUSION: The true impact of COVID-19 on colorectal cancer is yet to be uncovered as future mortality estimates from CRC are ongoing. Due to the widespread closure of endoscopy centers and delay in screening, we believe that the pandemic worsened the screening disparities most prevalent among minority populations. Our study points to the drastic reduction of screening for all races, especially for African Americans.

Background There is limited knowledge about adenoma detection rates (ADRs) in patients with a positive fecal immunochemical test (FIT). We hypothesized that colonoscopy performed after FIT would result in higher ADRs. Methods We reviewed ADRs for colonoscopies performed after a positive FIT test and compared them to ADR rates for routine colonoscopy performed without an initial FIT test between November 2014 and March 2017 at multiple endoscopy sites. Results A total of 979 patients underwent a FIT testing in the Texas panhandle, of whom 12.1% (n=119) tested positive. Also, 32.8% (n=39) were found to have one or more tubular adenomatous polyps on final pathological examination. Among these patients, the majority were female (64.1%; n=25). Of the patients, 15.9% (n=19) had a hyperplastic polyp, 1.7% (n=2) had findings consistent with ulcerative colitis, and 0.8% (n=1) were positive for an adenocarcinoma. In the control group of 2,603 patients in whom routine colonoscopy was performed as the initial tool for screening, 719 were found to have one or more tubular adenomas, with an ADR rate of 27.5%. In this group, the cancer rate was found to be 1%. Conclusions There was a significant increase in the ADR when colonoscopy is conducted after a positive FIT test. Recommending colonoscopies after a positive FIT test will not only improve ADRs significantly but also lower the overall healthcare cost for screening colon cancer in this era of escalating healthcare costs.
RESUMEN
Large bone defects from trauma or cancer are difficult to treat. Current treatment options include the use of external fixation with bone transport, bone grafting, or amputation. These modes of therapy continue to pose challenges as they are associated with high cost, failure, and complication rates. In this study, we report a successful case of bone defect treatment using personalized 3D-printed implant. This is the longest known follow-up using a 3D-printed custom implant for this specific application. Ultimately, this report adds to existing literature as it demonstrates successful and maintained incorporation of bone into the titanium implant. The use of patient-specific 3D-printed implants adds to the available arsenal to treat complex pathologies of the foot and ankle. Moreover, the technology's flexibility and ease of customization makes it conducive to tailor to specific patient needs.
RESUMEN
Ankle osteoarthritis affects a significant portion of the global adult population. Unlike other joints, arthritis of the ankle often develops as a response to traumatic injury (intra-articular fracture) of the ankle joints. The full mechanism leading to posttraumatic osteoarthritis of the ankle (PTOAA) is poorly understood. These deficits in knowledge pose challenges in the management of the disease. Adequate surgical reduction of fractured ankle joints remains the gold standard in prevention. The purpose of this review is to thoroughly delineate the known pathogenesis of PTOAA, and provide critical updates on this pathology and new avenues to provide therapeutic management of the disease.

OBJECTIVES: The complications associated with iliac crest bone-graft harvest have resulted in the development of alternative harvest sites. Lower extremity alternative sites that have been reported for foot and ankle procedures include greater trochanter, proximal tibia, distal tibia, and calcaneus. These sites have been studied in terms of complications, postoperative pain, and quality of the harvested bone. The long-term effect of the harvest on the bone of the calcaneus has not been reported. METHODS: Case report on incidental CT imaging 4 years after bone graft harvest from the calcaneus. RESULTS: This case demonstrates the failure of the calcaneal trabecular bone to regenerate after harvesting cancellous bone graft for foot fusion procedure. CONCLUSIONS: The calcaneal graft site should not be used for a repeat bone-graft harvest without advanced imaging to confirm reconstitution of the harvest bed.
