Barriers and Facilitators of Colorectal Cancer Screening in a Federally Qualified Health Center (FQHC).

INTRODUCTION: Colorectal cancer is a leading cause of cancer-related mortality in the United States. Current screening recommendations for individuals aged 50 to 75 years include colonoscopy every 10 years, flexible sigmoidoscopy every 5 years, or annual stool-based testing. Stool-based testing, including fecal immunochemical tests (FITs), are cost effective, easy to perform at home, and noninvasive, yet many patients fail to return testing kits and go unscreened. The purpose of the study was to identify patient characteristics and perceived barriers and facilitators of FIT return. METHODS: Patients in a large, federally qualified health center who received a FIT kit order between January 1 and July 1, 2017 were identified. We compared sociodemographic and health characteristics between patients who returned and did not return FITs. We used telephone surveys to nonreturners to identify potential barriers (cost, knowledge, psychosocial factors) and facilitators (prepaid postage, outreach) of FIT kit return. An online survey of clinicians assessed perceived patient barriers and facilitators of colorectal cancer screening. RESULTS: Of the 875 patients who received a FIT order, 435 (49.7%) did not return the kit and 121 of the nonreturners completed a telephone survey. Current smokers had an increased risk of FIT nonreturn compared with never smokers (RR = 1.32; 95% CI, 1.13-1.54). Forgetfulness and lack of motivation were the most common FIT return barriers perceived by both patients and clinicians. Prepaid postage with return address on FIT return envelopes and live call reminders were the most commonly reported facilitators. Barriers and facilitators varied greatest between English- and Spanish-speaking patients. CONCLUSION: In this study, the most common perceived barriers to return of screening fecal test kits were forgetfulness and lack of motivation. The most common perceived facilitators were live call reminders and postage-paid return envelopes. Understanding barriers and facilitators to FITs may be necessary to enhance cancer screening rates in underserved patient populations.

Treatment of metastatic cutaneous Crohn disease with certolizumab.

Metastatic Crohn disease is a rare cutaneous manifestation of Crohn disease characterized by granulomatous lesions discontinuous with the diseased areas of the gastrointestinal tract. We report a case of a 32-year-old woman with history of Crohn disease who was admitted for treatment of cellulitis after presenting with a tender erythematous plaque of the left calf. Microbiological tests including tissue cultures were negative. A skin biopsy revealed granulomatous dermatitis consistent with metastatic cutaneous Crohn disease. Owing to concomitant perianal fistulas and abscesses and prior infusion reaction to infliximab, the patient was treated with certolizumab, a pegylated tumor necrosis factor (TNF) inhibitor combined with methotrexate resulting in complete resolution of the skin lesion. This case emphasizes the importance of recognizing this rare skin manifestation of Crohn disease and adds certolizumab as one of TNF inhibitors useful in the treatment of metastatic cutaneous Crohn disease.

Isolation of Leclercia adecarboxylata from a patient with a subungual splinter.

Leclercia adecarboxylata is a rarely described motile, aerobic, gram-negative bacillus reported to cause clinically significant solitary infections in immunocompromised patients and polymicrobial wound infections in immunocompetent patients [1-5]. We present a case of a polymicrobial infection including L. adecarboxylata in a healthy female patient with a subungual splinter, to increase awareness and aid in the diagnosis and treatment of cutaneous L. adecarboxylata infections. To our knowledge, this is the first reported case of trauma-related subungual L. adecarboxylata infection reported in the dermatology literature.

Levamisole toxicity mimicking autoimmune disease.

BACKGROUND: Levamisole is present as a contaminant or additive in most cocaine sold in the United States. Cases of agranulocytosis attributed to levamisole-tainted cocaine have been widely described. A vasculopathic reaction to levamisole has also been reported; however, diagnostic features such as antineutrophil cytoplasmic antibody (ANCA) and additional autoimmune marker positivity are not well recognized. As such, many patients are given a misdiagnosis, prompting aggressive and often unnecessary treatment. OBJECTIVE: We hope to educate practitioners about the clinical and laboratory features of levamisole-induced vasculopathy to ensure accurate diagnosis and management. METHODS: This was a case series. RESULTS: Six patients were admitted with purpuric lesions and vasculitic changes on biopsy specimen; 5 of them were given the diagnosis of and treated for autoimmune conditions before their true diagnosis was revealed. All patients had ANCA positivity, and 4 had additional abnormalities in autoimmune markers. All patients reported recent cocaine abuse, and were ultimately given the diagnosis of levamisole-induced vasculopathy. LIMITATIONS: This observational study is limited by sample size. CONCLUSIONS: Patients presenting with purpuric lesions with ANCA positivity should be assessed for cocaine exposure. It is important to recognize that levamisole may not only induce ANCA positivity but also other autoimmune marker abnormalities. Patients can often be treated with less aggressive therapeutic strategies than what is used for primary ANCA-associated vasculitides.

Cutaneous macroglobulinosis: a case series.

Cutaneous macroglobulinosis is a rare skin manifestation of Waldenstrom macroglobulinemia. It is characterized by the deposition of eosinophilic, immunoglobulin-derived material in the dermis. It typically presents as pink or skin-colored papules favoring the extensor surfaces of the extremities. There are 11 reported cases of cutaneous macroglobulinosis in the literature. In our consultative dermatopathology practice we encountered three additional cases. In Case 1, a 41-year-old female with a monoclonal immunoglobulin M (IgM)-kappa gammopathy developed skin-colored papules on her extensor extremities, forehead and back. Histopathologic and immunohistochemical analyses revealed periodic acid-Schiff (PAS)-positive pink material in the dermis that stained with IgM. In Case 2, an 83-year-old female with a monoclonal IgM-lambda paraproteinemia developed non-blanching papules and plaques on the lower extremities and cheeks. Skin biopsies showed a striking occlusion of the vessels with a PAS-positive eosinophilic precipitate, which was also found in the extravascular spaces and stained with IgM using direct immunofluorescence (DIF) and immunohistochemical stains. In Case 3, an 80-year-old male with Waldenstrom macroglobulinemia developed ulcerated papules and nodules on the lower extremities. The biopsy findings were similar to those of Case 2. We present a series of three patients with cutaneous macroglobulinosis and explore variations in the clinical and histopathological findings of this uncommon entity.

Adult T-cell leukemia/lymphoma with follicular mucinosis: an unusual histopathological finding and a commentary.

Follicular mucinosis is currently recognized as a histopathological finding characterized by the accumulation of mucin within follicular epithelium and is commonly associated with follicular mycosis fungoides (MF). We report the finding of follicular mucinosis in a cutaneous nodule of human T-lymphotropic virus type 1 (HTLV-1) associated adult T-cell leukemia/lymphoma (ATLL). The patient was a 69-year-old female of Caribbean descent with a history of ATLL who presented with erythematous nodules on the chest and abdomen. Histopathologic examination showed a pan-dermal infiltrate of medium-to-large sized atypical lymphocytes extending into follicular epithelium where they associated with large mucin deposits. Immunohistochemical stains showed that the atypical lymphocytes were positive for CD3, CD4 and CD25 and negative for CD30. Cutaneous lesions of ATLL, which often present histopathologically as an epidermotropic lymphoma with Pautrier-type collections, are often difficult to distinguish from MF. Until recently, lymphoma-associated follicular mucinosis seemed specific to MF and Sézary syndrome (SS), being reported only once in a lesion of ATLL. We report a second case of ATLL-associated follicular mucinosis to increase awareness of this possible association, and briefly review the literature of follicular mucinosis-associated hematologic malignancies, ultimately cautioning against the interpretation of all cutaneous lymphoma-related follicular mucinosis as MF/SS.

Outbreak of norovirus infection among river rafters associated with packaged delicatessen meat, Grand Canyon, 2005.

BACKGROUND: Norovirus is often transmitted by infected food handlers at the point of service, whereas reports of food contamination before wholesale distribution are rare. In September 2005, we investigated reports of gastroenteritis among rafters who went on unrelated trips on the Colorado River. METHODS: We surveyed all companies that launched rafting trips during the period from 14 August through 19 September 2005 to identify trips in which > or =3 rafters became ill. We conducted a case-control study. Case patients were persons who experienced diarrhea or vomiting that commenced < or =72 h after the trip launch; control subjects were persons who did not become ill < or =72 h after launch. We tested stool samples and food specimens for norovirus. We performed a traceback investigation of the suspected food vehicle and inspected the implicated processing plant. RESULTS: Three or more rafters developed gastroenteritis during 13 (14%) of 91 trips, for a total of 137 ill persons. Of the 57 case patients who became ill < or =72 h after trip launch, 55 (96%) reported eating delicatessen meat, compared with 75 (79%) of 95 control subjects (odds ratio, 7.3; 95% confidence interval, 1.7-66.7). All delicatessen meat eaten by case patients came from 1 batch purchased from 1 processing plant and had been sliced, vacuum-packed, and frozen (temperature, -23 degrees C) for 7-28 days. An employee sliced this batch with bare hands 1 day after recovery from gastroenteritis. Identical norovirus sequences were identified in stool specimens obtained from rafters on 3 different trips; 2 of 5 meat packages also tested positive for norovirus by reverse-transcriptase polymerase chain reaction and DNA hybridization. CONCLUSIONS: Food handlers can contaminate ready-to-eat meats with norovirus during processing. Meat-processing practices should include specific measures to prevent contamination with enteric viruses and subsequent widespread outbreaks.
