Nowadays, scientific findings in the field of regeneration of nervous system have revealed the possibility of stem cell based therapies for damaged brain tissue related disorders like stroke. Furthermore, to achieve desirable outcomes from cellular therapies, one needs to monitor the migration, engraftment, viability, and also functional fate of transplanted stem cells. ⋯ In this review we searched in PubMed search engine by using following keywords; "Stem Cells", "Cell Tracking", "Stroke", "Stem Cell Transplantation", "Nanoparticles", and "Magnetic Resonance Imaging" as entry terms and based on the mentioned key words, the search period was set from 1976 to 2012. The main purpose of this article is describing various advantages of molecular and magnetic resonance imaging of stem cells, with focus on translation of stem cell research to clinical research.

This double-blinded, randomized clinical trial was designed to evaluate the comparison of intravenous versus intraarticular (IA) administration of midazolam on postoperative pain after knee arthroscopy. ⋯ Results show the greater analgesic effect after IA administration of midazolam than after intravenous injection and hence, IA administration may be is the method of choice for pain relief after knee arthroscopy.

Echocardiography is one of the diagnostic tools that can be applied at the bedside, along with avoiding transporting critically ill patients. This prospective observational study was designed to assess the clinical applicability of the transthoracic echocardiography (TTE) device by noncardiologist intensivists. ⋯ Transthoracic approach can provide useful information on cardiac anatomy and function in most ICU patients along with detecting severe previously unknown conditions in some patients.

Few investigation has focused on the patients with lupus nephritis (LN) and neuropsychiatric systemic lupus erythematosus (NPSLE). This study was aimed to investigate the clinical features, mortality, and the predictors for mortality of this group of patients. ⋯ Most of SLE patients with LN and new-onset NPSLE are in an active disease state. NP manifestation itself was the leading cause of death during hospitalization. Childhood-onset NPSLE, AKI and pneumonia might be predictors of mortality, whereas CYC treatment might improve the prognosis.

Most of the ingested foreign bodies pass uneventfully through the gastrointestinal tract. However, long and rigid foreign bodies are associated with an increased risk of gastrointestinal impaction, perforation, and bleeding. ⋯ However, if it fails, the foreign body can be removed successfully with a laparoscopic gastrotomy. We devised an innovative technique by using pneumatic gastric insufflation and extracted the toothbrush by a tiny gastrotomy under local anesthesia.
