Novel integration of systems-based practice into internal medicine residency programs: the Interactive Cost-Awareness Resident Exercise (I-CARE)

BACKGROUND

The Accreditation Council for Graduate Medical Education and American Board of Internal Medicine have identified cost-awareness as an important component to residency training. Cost-awareness is generally not emphasized in current, traditional residency curricula despite the recognized importance of this topic.

DESCRIPTION

Using a traditional Morning Report structure and actual charge data from our institution, the charges associated with trainee-directed workup of clinical cases are compared in a friendly competition among medical students, interns, residents, and faculty.

EVALUATION

Anonymous, voluntary survey of all participants and comparison of expenditures by training level were used to assess this pilot program. The educational quality of the I-CARE was rated higher than the prior format of Morning Report by participants (10-point Likert scale; 8.57, 6.81 respectively; p < .001). Open-ended comments were overwhelmingly supportive from faculty and trainees. Cost was lower for attending physicians than for trainees ($1,027.45 vs. $4,264.00, p = .02) and diagnostic accuracy was also highest for attending physicians.

CONCLUSIONS

The I-CARE is easy and quick to implement, and the preliminary results show a popular cost-awareness educational experience for internal medicine trainees. Further study is needed to determine change in practice habits.

Isolated pancreatic tuberculosis: a case report and radiological comparison with cystic pancreatic lesions

Pancreatic tuberculosis is rare and can occur in the absence of evidence of tuberculosis elsewhere in the body. Here we review the radiological appearance of pancreatic tuberculosis and compare it with other cystic pancreatic lesions, including common lesions (pseudocysts, serous or mucinous cystadenomas, intraductal papillary mucinous neoplasm) and rare lesions such as solid pseudopapillary tumors, etc. Their typical localizations within the pancreas and their malignant potential are presented. Knowledge of these can assist radiologists and clinicians in selecting the best approach towards making the correct diagnosis.

Endoscopic ultrasound-guided fine-needle aspiration for the diagnosis of peripancreatic tuberculous lymphadenitis

The percentage of patients with atypical extrapulmonary forms of tuberculosis has been increasing. Among extrapulmonary tuberculosis cases, tuberculosis of the pancreas and peripancreatic lymph nodes is a rare clinical entity. Here, we present a case of peripancreatic tuberculous lymphadenitis diagnosed by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) both cytologically and microbiologically. A 23-year-old man had a 1-week history of epigastralgia and low-grade fever. Subsequently, he was found to have an abnormality on abdominal ultrasound. A computed tomography scan of the abdomen showed a solitary mass consisting of multiple cystic components with rim enhancement in the peripancreatic portion contiguous to the gall bladder. Endoscopic ultrasound-guided fine-needle aspiration was performed to confirm the diagnosis. The cytological examination revealed epithelioid cells with caseous necrosis, indicating tuberculosis. The aspirated fluid was positive by polymerase chain reaction (PCR) analysis and culture for Mycobacterium tuberculosis. Antituberculosis therapy with isoniazid, rifampicin, ethambutol, and pyrazinamide was started based on the PCR and cytology results, and a good response to the treatment was noted. Endoscopic ultrasound-guided fine-needle aspiration cytology with PCR analysis is very useful for the diagnosis of peripancreatic tuberculosis.

Autoimmune pancreatitis: more than just a pancreatic disease? A contemporary review of its pathology

CONTEXT

Autoimmune pancreatitis (AIP) is a chronic inflammatory condition of the pancreas constituting one quarter of Whipple resections performed for benign conditions in North America.

OBJECTIVE

We review the clinical, radiologic, and characteristic histopathologic patterns of this disease and discuss the extrapancreatic manifestations of AIP.

DESIGN

We searched the literature using MEDLINE and OVID, related conference abstracts, and bibliographies of selected studies.

RESULTS

Autoimmune pancreatitis predominantly affects elderly individuals, frequently presenting as obstructive jaundice and occasionally in association with other autoimmune diseases. The histology is characterized by a collar of periductal inflammation, obliterative phlebitis, and the absence of stigmata of alcoholic pancreatitis. A prepancreatectomy diagnosis can be rendered using a combination of clinical findings, radiologic features, elevated immunoglobulin G4 levels, endoscopic ultrasound-guided fine-needle aspiration biopsy, and response to steroids. The disease can involve the bile ducts (sclerosing cholangitis), gallbladder (lymphoplasmacytic sclerosing cholecystitis), and kidney (interstitial nephritis) and can form inflammatory masses in the lungs.

CONCLUSIONS

Despite significant evolution in our understanding of AIP, a prepancreatectomy diagnosis remains a challenge in the North American and European population.

Peripancreatic tuberculosis mimicking pancreatic neoplasia

Tuberculosis of the pancreas and peripancreatic lymph nodes is an extremely rare disorder that has been reported with increased frequency in the past several years. Despite the fact that abdominal tuberculosis can generally be managed by pharmacotherapy alone, invasive procedures are often used before the establishment of the correct diagnosis, sometimes leading to unnecessary interventions and delayed treatment. To set the stage for our review, we first describe a case of a 31-year-old woman from India who initially presented with nonspecific symptoms and a pancreatic cystic lesion but was later diagnosed with peripancreatic tuberculosis. We then present a review of the current literature on peripancreatic and pancreatic tuberculosis, with a focus on diagnosis and management of the disease, but we also touch on issues such as epidemiology, infection control, and tissue acquisition. Finally, we offer clues that can be used to help identify patients who present with otherwise vague symptoms who may harbor pancreatic or peripancreatic tuberculosis. It is our hope that this case report and review of the literature will raise awareness and improve the management of this uncommon but serious disorder.
