Review Case ReportsBone formation following lenalidomide-dexamethasone combination therapy in cases of multiple myeloma refractory to high-dose chemotherapy with bortezomib and autologous peripheral blood stem cell transplantation: report of a case and review of the literature.
A 41-year-old man presented with the chief complaint of right hip pain that had persisted for 6 months. F18-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging showed FDG accumulation in the right pubic bone. A bone biopsy specimen from the site revealed findings suggestive of a plasma cell tumor. ⋯ The patient was then administered eight cycles of combined lenalidomide-dexamethasone therapy, which resulted in a marked decrease of the FDG accumulation in the right pubic bone and disappearance of uptake in the right hip bone. There was radiographic evidence of bone formation at these sites. This is only the second reported case in which treatment with the immunomodulatory drug lenalidomide and concomitant dexamethasone has been found to induce bone formation.

Review Case ReportsTenosynovial giant cell tumor arising from the posterior cruciate ligament: a case report and literature review.
The localized form of tenosynovial giant cell tumor or pigmented villonodular synovitis is rarely intraarticular in the knee. We reported a 40-year-old woman with a tenosynovial giant cell tumor arising from posterior cruciate ligament (PCL). She suffered sudden knee pain and locking without any reason for two days. ⋯ The histopathology of the mass demonstrated a tenosynovial giant cell tumor. At six weeks follow-up, no clinical evidence of recurrence was noted. A Literature Review of tenosynovial giant cell tumor or pigmented villonodular synovitis arising from the PCL is present.

Spatial and temporal differences of HMGB1 expression in the pancreas of rats with acute pancreatitis.
We aimed to investigate the spatial and temporal differences in expression between HMGB1 and early-stage inflammatory cytokines (IL-1, IL-6 and TNF-α) in pancreas tissue in rats with acute pancreatitis. SD rats (BW 350 ± 30 g, n = 48) were randomly divided into the experimental group (n = 36) which were injected with 5% sodium taurocholate into the bilipancreatic duct retrogradely to produce acute necrotic pancreatitis (ANP) rat models, and the sham-operated (SO) group (n = 12) injected with equal dose of saline. The rats were sacrificed at different time points at 0 h, 3 h, 6 h, 12 h, and 24 h post modeling, respectively. ⋯ The HMGB1 level in the pancreatitis tissue did not change significantly at 3 h and 6 h (P > 0.05), however, it increased remarkably at 12 h, and maintained up to 24 h (P > 0.05). As a late inflammatory factor, the expression of HMGB1 in acute pancreatitis was obviously later than the early inflammatory factors IL-1, TNF-α and IL-6. HMGB1 may play a key role in maintaining the development of the acute pancreatitis.

Review Meta AnalysisEpsilon aminocaproic acid reduces blood transfusion and improves the coagulation test after pediatric open-heart surgery: a meta-analysis of 5 clinical trials.
Excessive postoperative blood loss after cardiopulmonary bypass is a common problem, especially in patients suffering from congenital heart diseases. The efficacy of epsilon aminocaproic acid (EACA) as a prophylactic treatment for postoperative bleeding after pediatric open-heart surgery has not been determined. This meta-analysis investigates the efficacy of EACA in the minimization of bleeding and blood transfusion and the maintenance of coagulation tests after pediatric open-heart surgery. ⋯ Prophylactic EACA minimizes postoperative blood transfusion and helps maintain coagulation in pediatric patients undergoing open-heart surgery. Therefore, the results of this study indicate that adjunctive EACA is a good choice for the prevention of postoperative blood transfusion following pediatric cardiac surgery.

Randomized Controlled TrialComparison of the neuroprotective effects and recovery profiles of isoflurane, sevoflurane and desflurane as neurosurgical pre-conditioning on ischemia/reperfusion cerebral injury.
There are a few reports regarding the comparison of these anesthetic agents, but previous studies mainly focus on the veterinary anesthesiology. Less attention has been focused comparing the effectiveness of these inhalational anesthetic agents in neurosurgery. This lack of interest is regretful particularly considering the fact that anesthetics during neurosurgery are an issue of extreme sensitivity and subtlety, where the cerebral oxygenation process plays a significant role in the neuroprotective mechanisms. ⋯ Sevoflurane offers several advantages, including a relative lack of airway irritation, a more rapid onset and recovery, and greater hemodynamic stability than other potent inhaled agents. These properties would appear to afford sevoflurane significant clinical potential.
