Invasion of distant tissues by tumor cells is the primary cause of therapeutic failure in the treatment of malignant lung cancer cells. Receptor activator of nuclear factor-κB ligand (RANKL) and its receptor, RANK, play a key role in osteoclastogenesis and tumor metastasis. Intercellular adhesion molecule-1 (ICAM-1, also called CD54), a member of the(More)
Rhabdomyosarcoma is the most common tumour of the lower genitourinary tract in children in the first two decades. Paratesticular rhabdomyosarcoma is associated with a significantly better outcome than lesions elsewhere in the genitourinary tract. Although ultrasound is considered the imaging modality of choice for evaluating intrascrotal pathology, the(More)
OBJECT To determine the safety and usefulness of performing surgery via the occipital transtentorial approach to treat anterosuperior cerebellar tumors, evaluation of 14 patients was performed over a 5-year period. METHODS The study was performed in 14 patients, aged 6 months to 71 years, who harbored anterosuperior cerebellar tumors of the posterior(More)
Of 250 patients admitted with aneurysmal subarachnoid hemorrhage (SAH) from 1994 to 2000, 16 had massive intra-sylvian hematomas. To predict the useful determinants of the clinical outcome for such patients we analyzed our last 16 cases. The study was performed in 2 parts. Part 1 covered the period from 1994 to 1996 and included 5 patients who underwent(More)
A new embolization agent combining ethanol-estrogen and polyvinyl acetate was evaluated angiographically and histologically in 18 canine renal arterial systems. Peripheral vessels of less than 100 microns diameter were obliterated by thrombus induced by ethanol-estrogen, and larger vessels were obliterated by polyvinyl acetate casts and/or thrombus. This(More)
This experimental report evaluates the histopathological effects of a new embolization method using estrogen-alcohol (E-A) and polyvinyl acetate solution (PVac) as tested on 21 mongrel dogs. Three other animals treated with normal saline served as controls. All agents were introduced through an isolated cortical artery. Estrogen-alcohol induced immediate(More)
BACKGROUND Chronic ectopic pregnancy is an enigma. The clinical presentation can be mild, with absent or subtle symptoms. Ovarian pregnancy usually ends with rupture. We report the first case of unruptured chronic ovarian pregnancy that was initially diagnosed by peritoneal washing cytology. CASE A 35-year-old woman suffered from low abdominal pain during(More)
A new liquid embolization material applicable to intracranial lesions was evaluated by selective renal artery embolization in mongrel dogs. Absolute and diluted ethanol, estrogen, and estrogen in 25% ethanol (ethanol-estrogen) were injected. The embolization and side effects were investigated angiographically and histologically. Ethanol-estrogen caused(More)
Ticlopidine is a powerful antiplatelet activator that inhibits adenosine diphosphate (ADP)-induced platelet aggregation. Its most common side-effects are skin rashes, diarrhea and neutropenia. Aplastic anemia is rare. This paper reports a patient with severe aplastic anemia that developed after the use of ticlopidine. The 85-year-old woman developed fever,(More)
BACKGROUND Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumours of the gastrointestinal tract, histologically identified as highly cellular spindle or epithelioid cell tumours, and often positive for CD34 (60-70%). Kaposi's sarcomas (KSs) are similar to GISTs: they are most often found in the gastrointestinal tract (although(More)
