Abstract

Desmoplastic fibroma is a very rare primary tumor of bone, closely related to aggressive fibromatosis of soft tissue. Although considered a benign lesion, it can be very aggressive locally and has a high rate of local recurrence after incomplete surgical excision. Radiologically, the lesion shows no distinctive features, often simulating osteosarcoma, fibrous dysplasia, or fibrosarcoma. Rib involvement by desmoplastic fibroma is extremely rare. We present two cases of desmoplastic fibroma involving this unusual location with lytic costal lesion and chest wall extension. Histological examination after surgical resection revealed that the tumor consisted of spindle cells with small, elongated nuclei in a background of numerous collagen fibers and infiltrating lamellar bone. There was no evidence of nuclear atypia, mitotic activity, or necrosis. We also discuss histological differential diagnosis as well as clinical features and the radiological and pathologic findings of this rare disease. Recognition of this entity is important to ensure proper surgical treatment.

Abstract

Sclerosing stromal tumours are rare benign ovarian neoplasms of the sex cord stromal that occur predominantly in the second and third decades of life. Herein, we report two cases of sclerosing stromal tumour of the ovary. The two patients were 16 and 45 years old and both presented with pelvic pain. Ultrasonography demonstrated a heterogeneous solid mass of the left and right ovary, respectively, with some cystic foci in the second tumour. Laboratory tests including tumour markers and serum hormonal assays were normal in both cases. The two patients underwent left and right salpingo-oophrectomy, respectively. Microscopically, the tumours showed a pseudolobular pattern with cellular areas separated by oedematous and collagenous areas. The cellular areas were richly vascularized, with a hemangiopericytic pattern, and were composed of an admixture of theca-like and spindle-shaped cells. Immunohistochemical studies showed that the tumour cells were positive for smooth muscle actin, inhibin and vimentin, but negative for cytokeratin. The final pathological diagnosis was sclerosing stromal tumour. Postoperative course was uneventful for both patients.

Abstract

Localized giant pseudopolyposis is a rare complication in inflammatory bowel disease defined as a pseudopolyp (isolated or clustered) larger than 1.5 cm in size. Giant pseudopolyps are more commonly found in ulcerative colitis compared to Crohn's disease and mainly involve the left colon. A 26-year-old male patient with a two-year history of Crohn's disease was admitted with increasing abdominal pain, vomiting, anorexia, weight loss and fever. On physical examination, the abdomen was diffusely tender. Computed tomography showed diffuse irregular thickening of the ileal wall and stenosis of the terminal ileum. The patient underwent ileo-cecal resection with re-anastomosis. The ileal portion of the resected specimen harboured multiple finger-like pedunculated polyps, with the smallest measuring 0.5 cm and the largest measuring 1.8 cm. Histologically, the polyps were consistent with granulation tissue. No evidence of dysplasia or malignancy was found. The post-operative course was uneventful considering one month follow-up. This report illustrates an unusual case of giant pseudopolyposis involving the ileum in a patient with Crohn's disease. The natural history of these lesions, as well as their optimal management, remain uncertain.

Abstract

We report on the first observation of Bragg scattering of an ultracold $^6$Li Fermi gas. We demonstrate a Ramsey-type matter-wave interferometer based on Bragg diffraction and find robust signatures of persistent matter wave coherences using an echo pulse sequence. Because of the Pauli principle, the diffracted fermions oscillate nearly unperturbed in the trapping potential for long times beyond 2 s. This suggests extremely long coherence times. On these timescales, only the presence of a $^{87}$Rb cloud seems sufficient to induce noticeable perturbations., Comment: 5 pages, 4 figures

Abstract

Collective interaction of light with an atomic gas can give rise to superradiant instabilities. We experimentally study the sudden build-up of a reverse light field in a laser-driven high-finesse ring cavity filled with ultracold thermal or condensed atoms. While superradiant Rayleigh scattering from atomic clouds is normally only observed at very low temperatures (i.e. well below $1 \mu$K), the presence of the ring cavity enhances cooperativity and allows for superradiance with thermal clouds as hot as several $10 \mu$K. A characterization of the superradiance at various temperatures and cooperativity parameters allows us to link it to the collective atomic recoil laser., Comment: 4 pages, 4 figures

8. Coexistence of xanthogranulomatous cholecystitis and gallbladder adenocarcinoma: a fortuitous association?

Abstract

Xanthogranulomatous cholecystitis is a relatively uncommon variant of chronic cholecystitis, characterized by marked thickening of the gallbladder wall and dense local adhesions. Not only does xanthogranulomatous cholecystitis mimic malignancy, it can also be infrequently associated with gallbladder carcinoma in 0.2% to 35.4% of cases. Herein, the authors report a new case of xanthogranulomatous cholecystitis concomitant with gallbladder adenocarcinoma in a 65-year-old female patient. Because of its overlapping clinical, radiological and macroscopic findings with gallbladder cancer, definitive diagnosis of xanthogranulomatous cholecystitis relies on extensive sampling and thorough microscopic examination of the surgical specimen to exclude the possibility of coexisting tumour. It is still a matter of debate whether xanthogranulomatous cholecystitis is truly a precursor of gallbladder carcinoma or if it is just an incidental finding. This aspect needs to be explored in the future with further studies.

Abstract

Management and planning of coastal and marine areas are complex processes that are more and more required to effectively support a coordinated development of socio-economic activities. In managing coastal and marine activities, it is important to have good governance with assistant from spatial data infrastructure (SDI), to ensure sustainable planning and development of marine area. GIS and related technologies are becoming increasingly used to aid in the administration and management of the marine environment. This article describes the implementation of SDI, demonstrating how an interoperable system can provide strong support in implementing the integrated coastal and marine management. It also focuses on the degree of GIS implementation, the issues, the limitation and engagement in establishing SDI-ICMM in Tunisia.
