Caring for the healthcare professional.

Purpose Hospitals must systematically support employees in innovative ways to uphold a culture of care that strengthens the system. At a leading Canadian academic pediatric rehabilitation hospital, over 90 percent of clinicians viewed Schwartz Rounds™ (SR) as a hospital priority, resulting in its formal implementation as a quality improvement initiative. The purpose of this paper is to describe how the hospital implemented SR to support the socio-emotional impact of providing care. Design/methodology/approach This quantitative descriptive study provides a snapshot of the impact of each SR through online surveys at four assessment points (SR1-SR4). A total of 571 responses were collected. Findings All four SR addressed needs of staff as 92.9-97.6 percent of attendees reported it had a positive impact, and 96.4-100 percent of attendees reported each SR was relevant. Attendees reported significantly greater communication with co-workers after each SR ( p<0.001) and more personal conversations with supervisors after SR2 and SR4 ( p<0.05) compared to non-attendees. Attending SR also increased their perspective-taking capacity across the four SR. Practical implications As evidenced in this quality improvement initiative, SR addresses staff's need for time to process the socio-emotional impacts of care and to help reduce those at risk for compassion fatigue. SR supports and manages the emotional healthcare culture, which has important implications for quality patient care. Originality/value This research details an organization's process to implement SR and highlights the importance of taking care of the care provider.

Multicenter experience with upper gastrointestinal polyps in pediatric patients with familial adenomatous polyposis.

BACKGROUND: Familial adenomatous polyposis (FAP) is a hereditary cancer syndrome that includes gastro-duodenal involvement, polyposis, and a propensity to adenocarcinoma necessitating endoscopic surveillance. There are few data describing pediatric upper gastrointestinal FAP resulting in conflicting screening recommendations. OBJECTIVES: To characterize pediatric gastroduodenal FAP and to investigate the association between symptoms at endoscopy and APC mutation analysis with endoscopic-histologic findings warranting surveillance. METHOD: A retrospective chart review was performed, including all children with FAP who underwent upper endoscopy (EGD) at two institutions; (UNMC: 1992-2002, JHH: 1983-2002), all biopsies were reviewed and the APC mutations present in the cohort of patients were correlated to the pattern of severity of endoscopic findings and the frequency of APC mutations identified through commercially available testing for FAP (Labcorp: 1998-2002). RESULTS: Twenty-four patients from 21 families underwent 49 EGDs. Eighty-three percent were asymptomatic at the time of endoscopy. The most common finding was fundic gland polyposis (FGP) (51%), of which 42% and 15% harbored dysplasia and changes indefinite for dysplasia, respectively. Periampullary duodenal adenomata were present in 41% of patients with one patient necessitating ampullectomy. Symptoms at endoscopy were not predictive of premalignant changes. In 15 patients where the APC mutation was known patients with dysplastic FGP, gastric, or duodenal adenoma were more likely to harbor a mutation between codons 1225-1694 than the reference population (p= 0.006). CONCLUSIONS: All pediatric patients with FAP warrant upper gastrointestinal screening and surveillance endoscopy from the time of initial colonoscopy irrespective of referable symptoms. Patients with APC mutation between codon 1225-1694 may be more susceptible to aggressive gastroduodenal involvement in FAP.

Diagnosis of Wihipple disease by immunohistochemical analysis: a sensitive and specific method for the detection of Tropheryma whipplei (the Whipple bacillus) in paraffin-embedded tissue.

Whipple disease is a rare infection characterized clinically by diarrhea, fever, weight loss, arthralgia, malabsorption, and other systemic manifestations. The etiologic agent, Tropheryma whipplei, has been cultured only rarely. By using a polyclonal rabbit antibody produced against a cultured strain of T whipplei, tissue sections from 18 patients with Whipple disease were studied. Specimens from patients with histologic mimics and other infections served as control specimens. Immunostaining was identified in all 18 patients. Granular immunostaining was observed similar to that in periodic acid-Schiff (PAS) stains. In 2 patients, immunostaining was identified in specimens negative by H&E and PAS stains. In 4 patients studied before and after antibiotic therapy, immunostaining was retained but diminished in intensity and quantity. Immunostaining was not identified in any control specimen. Immunohistochemical analysis is a sensitive and specific method for the diagnosis of Whipple disease in paraffin-embedded tissue and may provide new opportunities to investigate the pathogenesis of the infection.

Gastric adenomas: intestinal-type and gastric-type adenomas differ in the risk of adenocarcinoma and presence of background mucosal pathology.

Gastric adenomas are neoplastic growths characterized by localized, polypoid proliferations of dysplastic epithelium. They frequently arise in stomachs with a background of mucosal atrophy and intestinal metaplasia, and a higher risk of adenocarcinoma elsewhere in the stomach has been reported in patients with gastric adenomas. Additionally, some gastric adenomas themselves demonstrate neoplastic progression to infiltrating adenocarcinoma. However, previous studies have not comprehensively evaluated the background gastric mucosa and risk of adenocarcinoma, particularly in relation to the histologic classification of adenomas as either intestinal-type or gastric-type. We studied 61 gastric adenomas from 51 patients between 1985 and 2001. The adenomas were classified as intestinal-type (containing at least focal goblet cells and/or Paneth cells), gastric-type (lined entirely by gastric mucin cells on PAS/alcian blue stain), or indeterminate. We evaluated the histologic features of both the adenomas (location, multiplicity, degree of dysplasia, presence of adenocarcinoma within the polyp) and the surrounding gastric mucosa (presence of gastritis, intestinal metaplasia, and adenocarcinoma). Gastric adenomas were distributed equally throughout the stomach, were most frequently solitary (82%), and contained adenocarcinoma in nine cases (14.8%). There were 34 intestinal-type adenomas (56%) in 31 patients, 25 gastric-type adenomas (41%) in 18 patients (including 10 patients with familial adenomatous polyposis), and 2 of indeterminate type (3%). Intestinal-type adenomas were significantly more likely than gastric-type adenomas to show high-grade dysplasia (p <0.0001), adenocarcinoma within the polyp (p = 0.016), intestinal metaplasia in the surrounding stomach (p <0.000001), and gastritis (p = 0.002). Patients with intestinal-type adenomas were also more likely to have separate adenocarcinomas (five cases vs 0 cases), although this did not reach statistical significance. Gastric adenomas are rarely truly "sporadic" lesions. In any individual patient complete removal of the adenoma should be performed, and thorough biopsy of the surrounding gastric mucosa is essential to understand the clinicopathologic context of the adenoma.

Colchicine effect in a colonic hyperplastic polyp. A lesion mimicking serrated adenoma.

Colchicine effect has been described recently in gastrointestinal biopsies, where it can result in accumulation of metaphase mitoses and epithelial disorganization. We describe the case of a colonic hyperplastic polyp with colchicine effect from a 52-year-old woman who was receiving colchicine for primary biliary cirrhosis. Biopsy of the polyp revealed prominent metaphase mitoses and focal loss of nuclear polarity in the surface epithelium, features that mimicked a serrated adenoma. Distinguishing between hyperplastic polyp and serrated adenoma is important because of the different management implications and the increased potential for neoplastic progression in the latter.

Autoimmune gastritis: distinct histological and immunohistochemical findings before complete loss of oxyntic glands.

Autoimmune gastritis (AG) can be easily recognized when the histological features are fully developed, but recognizing AG before the complete loss of the oxyntic mucosa is more challenging. One feature of fully developed AG is enterochromaffin cell-like (ECL) hyperplasia, but its presence or absence in earlier stages of AG has not been fully evaluated. A retrospective study of biopsy specimens from 40 patients was performed; all of the patients were originally diagnosed with possible AG based on the presence of lymphocytic infiltration and damage to oxyntic glands and/or the presence of metaplastic epithelium that disproportionately involved the body mucosa. Nineteen cases had follow-up serological studies for anti-parietal cells and/or anti-intrinsic factor antibodies: 13 were positive and 6 negative. The remaining 21 cases were indeterminate because of incomplete testing. The histological findings were similar in the patients who were serologically positive and those who were indeterminate for AG. In all of these cases, the oxyntic mucosa showed lymphoplasmacytic infiltrates within the lamina propria with focal gland infiltration and damage. Sixty-five percent (22/34) of the cases showed intestinal and/or pyloric metaplasia, and 85% (29/34) showed parietal cell pseudohypertrophy. Chromogranin stains were performed in 11 of 13 cases with positive serological markers for AG, and all showed at least linear ECL cell hyperplasia. In contrast, none of the six cases with negative serological studies had linear ECL cell hyperplasia, P <.001. In conclusion, the following constellation of findings supports a diagnosis of AG before the complete loss of oxyntic mucosa: deep or diffuse lymphoplasmacytic infiltrates within the lamina propria with foci of gland infiltration and damage, epithelial metaplasia, parietal cell pseudohypertrophy, and ECL cell hyperplasia at the linear or greater level.

Potent nonsteroidal progesterone receptor agonists: synthesis and SAR study of 6-aryl benzoxazines.

Novel 6-aryl benzoxazines were prepared and examined as progesterone receptor (PR) modulators. In contrast to the structurally related 6-aryl dihydroquinoline PR antagonists, the 6-aryl benzoxazines were potent PR agonists. Compounds 4e, 5b, and 6a with the 2,4,4-trimethyl-1,4-dihydro-2H-benzo[d][1,3]oxazine core were the most potent PR agonists in the series with sub-nanomolar activities (EC(50) 0.20-0.35nM). Compound 6a was more potent than progesterone (P4) in the in vivo decidualization assay in an ovariectomized female rat model by subcutaneous administration with an ED(50) of 1.5mg/kg (vs 5.62mg/kg for P4).
