Objective
The aim of the project was to assess the effectiveness and safety of weekly epoetin-beta (EB) in patients with gastrointestinal cancer (GIC) subjected to concomitant chemoradiotherapy (CCTRT). 相似文献72.

Extravasation of chemotherapy is a feared complication of anticancer therapy. The accidental leakage of cytostatic agents
into the perivascular tissues may have devastating short-term and long-term consequences for patients. In recent years, the
increased focus on chemotherapy extravasation has led to the development of international guidelines that have proven useful
tools in daily clinical practice. Moreover, the tissue destruction in one of the most dreaded types of extravasation (ie,
anthracycline extravasation) now can effectively be prevented with a specific antidote, dexrazoxane. 相似文献

Hypoxia is related to poor prognosis because it is associated to chemo-and radioresistance. During recent years the evolution
of imaging methods like PET/CT and MRI has meant the appearance of new perspectives with direct implications in radiation
therapy. We discuss previous experiences in staging, planning and in the follow-up process with these techniques for measuring
tumour hypoxia. 相似文献

Background
Bortezomib, a proteasome-specific inhibitor, has emerged as a promising cancer therapeutic agent. However, development of resistance to bortezomib may pose a challenge to effective anticancer therapy. Therefore, characterization of cellular mechanisms involved in bortezomib resistance and development of effective strategies to overcome this resistance represent important steps in the advancement of bortezomib-mediated cancer therapy. 相似文献75.
Background
The fibromyalgia syndrome (FMS) is suggested to be a manifestation of depression or affective spectrum disorder. We measured the cognitive style of patients with FMS to assess personality styles in 44 patients with fibromyalgia syndrome (FMS) by comparing them with 43 patients with major depressive disorder (MDD) and 41 healthy controls (HC). 相似文献76.

Introduction Choroid plexus cysts can lead to isolation of the lateral ventricles and distension of the third ventricle. We present an
ultrasonographic video documentation of an infant with variably shaped and localized choroid plexus cyst of the third ventricle.
Case report An infant had periods of increased intracranial pressure with changing dilatation of the first to third ventricle. Cerebral
ultrasonography of the not crying boy demonstrated a choroid plexus cyst limply hanging down from the roof of the third ventricle
to the beginning of the aqueduct of Sylvius. During crying, the cyst prolapsed from the third into left lateral ventricle
and was strangled by the foramen of Monro. Endoscopic cyst fenestration and third ventriculostomy continuously solved the
problem of intermittent hydrocephalus occlusus.
Conclusion Depending not only on localization and size but also on cyst form and cerebrospinal fluid pressure, a single choroid plexus
cyst can cause various obstructions of cerebrospinal fluid pathways. 相似文献

Introduction Iniencephaly, a neural tube defect involving occiput and inion and combined with rachischisis of the cervical, thoracic spine,
and retroflexion position of the head is a very rare congenital abnormality of the fetus–newborn with a 0.1–10 of 10,000 prevalence.
This abnormality’s prognosis is thought to be dismal. This abnormality can be associated with other abnormalities such as
anencephaly, encephalocele, hydrocephalus, cyclopia, absence of the mandible, cleft lip and palate, cardiovascular disorders,
diaphragmatic hernia, renal abnormalities, overgrowth of the arms compared to the legs, and club food and gastrointestinal
atresia.
Discussion Most of the patients are dead born, and the others die in a few hours. There are only six previously documented long-term
survivors. In our case, our patient with iniencephalic signs and findings is still living. She is 2 years old now. We think
that this patient presents a mild form of iniencephaly. 相似文献
