Inflammatory fibroid polyp of the ileum presenting with small bowel obstruction in an adult patient: a case report

<p>Abstract</p> <p>Introduction</p> <p>Inflammatory fibroid polyps are rare benign tumors of the gastrointestinal tract with the gastric antrum being the most common site, followed by the ileum. Histogenesis is still unknown and controversial. Inflammatory fibroid polyps are one of the rare benign conditions leading to intestinal obstruction in adults.</p> <p>Case presentation</p> <p>A 54-year-old Caucasian man presented with acute abdomen pain and a two month history of intermittent cramping and lower abdominal pain. Computed tomography imaging demonstrated a partial intestinal obstruction in the location of the terminal ileum. An ileo-ileal intussusception due to a mass lesion 15 cm proximal to the caecum was found on exploratory laparotomy. Intussusception was spontaneously reduced during exploration and a wedge resection was performed to the affected bowel segment. Histopathologic examination showed the mass to be an inflammatory fibroid polyp.</p> <p>Conclusion</p> <p>Although inflammatory fibroid polyps are rare and benign, in the case of intestinal obstruction the only solution is a surgical approach.</p

A quantitative analysis of the effect of insulin-like growth factor-1 infusion during mandibular distraction osteogenesis in rabbits.

AIM: To quantify, by histomorphometry, the effects of local insulin-like growth factor-1 (IGF-1) during mandibular distraction at various rates. METHODOLOGY: Mature rabbits underwent bilateral mandibular corticotomy and distraction lengthening. Recombinant IGF-1 was administered to two groups of rabbits via osmotic infusion pumps. Distraction regimes were as follows: Group A, 1 mm/day for 15 days; Group B, as for A plus IGF-1; Group C, 3 mm/day for 5 days; Group D, as for C plus IGF-1; and Group E, sham-operated controls. After a 28-day consolidation period, rabbits were sacrificed and bone deposition quantified using DEXA scanning, three-point bending, histological examination and sampled for histomorphometric analysis. RESULTS: DEXA scanning and three-point bending failed to detect any effect of distraction rate or of IGF-1 infusion. Histological and histomorphometric analysis suggested 1 mm/day to be the ideal distraction rate, as this was associated with greater osteoblastic activity and consistent bony union. However, IGF-1 infusion significantly enhanced osteoblastic activity at both distraction rates and resulted in bony union when distraction was performed at 3 mm/day. CONCLUSIONS: Distraction osteogenesis at a rate of 1 mm/day provides greater osteogenic stimulus than 3 mm/day. Exogenous IGF-1 has a positive influence on osteoblastic activity during distraction. Its effect is probably minimised by high levels of endogenous IGF-1

Benefit of Semiannual Ipsilateral Mammographic Surveillance Following Breast Conservation Therapy

PURPOSE: To compare cancer recurrence outcomes on the basis of compliant semiannual versus noncompliant annual ipsilateral mammographic surveillance following breast conservation therapy (BCT). MATERIALS AND METHODS: A HIPAA-compliant retrospective review was performed of post-BCT examinations from 1997 through 2008 by using a deidentified database. The Committee on Human Research did not require institutional review board approval for this study, which was considered quality assurance. Groups were classified according to compliance with institutional post-BCT protocol, which recommends semiannual mammographic examinations of the ipsilateral breast for 5 years. A compliant semiannual examination was defined as an examination with an interval of 0–9 months, although no examination had intervals less than 3 months. A noncompliant annual examination was defined as an examination with an interval of 9–18 months. Cancer recurrence outcomes were compared on the basis of the last examination interval leading to diagnosis. RESULTS: Initially, a total of 10 750 post-BCT examinations among 2329 asymptomatic patients were identified. Excluding initial mammographic follow-up, there were 8234 examinations. Of these, 7169 examinations were semiannual with 94 recurrences detected and 1065 examinations were annual with 15 recurrences detected. There were no differences in demographic risk factors or biopsy rates. Recurrences identified at semiannual intervals were significantly less advanced than those identified at annual intervals (stage I vs stage II, P = .04; stage 0 + stage I vs stage II, P = .03). Nonsignificant findings associated with semiannual versus annual intervals included smaller tumor size (mean, 11.7 vs 15.3 mm; P = .15) and node negativity (98% vs 91%, P = .28). CONCLUSION: Results suggest that a semiannual interval is preferable for ipsilateral mammographic surveillance, allowing detection of a significantly higher proportion of cancer recurrences at an earlier stage than noncompliant annual surveillance. © RSNA, 201
