Randomized Controlled TrialAdministration of higher doses of amikacin in early stages of sepsis in critically ill patients.
High-dose extended-interval dosage (HDED) regimen of aminoglycosides is now considered as the standard dosage strategy in sepsis. Although safety and efficacy of this dosing regimen is well studied, but new experiments show increased the risk of resistance development associated with %T>MIC less than 60% of the dosing interval following extended interval dosing. Moreover, limited information is available about safety of more frequent administration of high dose aminoglycosides. ⋯ This indicates a safer pattern of moderate doses with more frequent administration of amikacin at the tubular injury level. Higher doses of amikacin could be safely administered to achieve PK/PD goal of Cmax>40 and %T>MIC more than 60% of the dosing interval. This dosing regimen would be considered as an alternative to minimize the resistance development associated with the extended-interval dosing in septic patients with multi-drug resistant gram-negative organisms.

The trend of indexed papers in PubMed covering different aspects of self-immolation.
Self-immolation is a fatal and devastating method of committing suicide used around the world. The chief aim of the present article is to look at the trend of indexed papers in PubMed covering different aspects of self-immolation. PubMed search engine (http://www.ncbi.nlm.nih.gov) was searched by using six keywords i.e. "self-immolation", "self-inflicted burn", "self-burning", "self-incineration", "suicidal burns" and "suicide by burning". ⋯ Three journals i.e. Burns, Journal of Burn Care and Rehabilitation and Journal of Forensic Sciences hosted for more than 37% of all those indexed articles. However, given the increasing trend of self-immolation still more studies are needed to shed light on the diverse aspects of this appalling human behavior.

Randomized Controlled Trial Comparative StudyAxillary nerve block in comparison with intravenous midazolam/fentanyl for painless reduction of upper extremity fractures.
The painful nature of fractures has made it inevitable to use various anesthetic techniques to reduce or immobilize fractured parts. In the present study, axillary nerve block was compared with intravenous midazolam/fentanyl to induce anesthesia for Painless Reduction of Upper Extremity Fractures. The subjects in the present clinical trial consisted of 60 patients with upper extremity fractures. ⋯ In contrast, the recovery time was much shorter in the ANB group (P<0.001). No life or organ threatening complications were observed in the two groups. Axillary nerve block can be considered an appropriate substitute for intravenous sedation in painful procedures of the upper extremity.

Randomized Controlled TrialProphylactic administration of fibrinogen concentrate in perioperative period of total hip arthroplasty: a randomized clinical trial study.
According to limitations in blood product resources and to prevent unnecessary transfusions and afterwards complications in perioperative period of total hip arthroplasty, authors administered fibrinogen concentrate in a pilot randomized clinical trial to evaluate bleeding and need to blood transfusion in preoperative period. Thirty patients (3-75 years old) with ASA physical status class I or II and candidate for total hip arthroplasty consequently enrolled in this study and randomly assigned into two groups: taking fibrinogen concentrate and control. Two groups were similar in serum concentration of fibrinogen, hemoglobin, and platelet preoperatively. ⋯ By adjusting time factor for two groups, we identified that the patients in fibrinogen group had lower perioperative bleeding after adjusting time factor for two groups (P=0.046). None of the patients had complications related to fibrinogen concentrate administration. The prophylactic administration of fibrinogen concentrate was safe and effective in reducing bleeding in the perioperative period of total hip arthroplasty.

Randomized Controlled TrialVertical infraclavicular block with local anesthetic injections at different currents.
Injecting local anesthetic at the seeking current would be appealing. It would save time and avoid potentially dangerous manipulations of the needle. This study aimed to test the hypotheses that in vertical infraclavicular block, injecting local anesthetic at a seeking current of 0.8 mA would produce the same quality of block as injecting at ≤0.5mA. ⋯ We had patients in both groups who developed complete anesthesia of the hand within 25 minutes. We conclude that the injection at 0.8 mA would result in a similar quality of block to one injected at ≤0.5 mA. The difference between two groups was not statistically significant.
