The isolation of the antitumor antibiotic anthramycin in the 1960s prompted extensive research into pyrrolo[1,4]benzodiazepines (PBD) as potential therapeutics for the treatment of cancers. Since then, nearly 60 PBD natural products have been isolated and evaluated with regard to their biological activity. Synthetic studies and total syntheses have enabled access to PBD analogues, culminating in the development of highly potent anticancer agents. This review provides a summary of the occurrence and biological activity of PBD natural products and covers the strategies employed for their total syntheses.
Rapid infusion of warmed blood products is the cornerstone of trauma resuscitation and treatment of surgical and obstetric massive hemorrhage. Integral to optimizing this delivery is selection of an intravenous (IV) catheter and use of a rapid infusion device (RID). We investigated which IV catheter and RID system enabled the greatest infusion rate of blood products and the governing catheter characteristics.
The maximum flow rates of nine IV catheters were measured while infusing a mixture of packed red blood cells and fresh frozen plasma at a 11 ratio using a RID with and without a patient line extension. To account for IV catheters that achieved the RID's maximum 1000 ml/min, the conductance of each infusion circuit configuration was calculated.
IV catheters of 7-Fr caliber or higher reached the maximum pressurized flow rate. The 9-Fr multi-lumen access catheter (MAC) achieved the greatest conductance, over sevenfold greater than the 18 g peripheral catheter (4.6 vs. 0.6ml/min/mmHg, p <.001). Conductance was positively correlated with internal radius (β= 1.098, 95% CI 4.286-5.025, p <.001) and negatively correlated with length (β= -0.495, 95% CI -0.007 to 0.005, p <.001). Use of an extension line (β= -0.094, 95% CI -0.505 to -0.095, p= .005) was independently associated with reduced conductance in large caliber catheters.
Short, large-diameter catheters provided the greatest infusion rates of massive transfusion blood products for the least pressure. For patients requiring the highest transfusion flow rates, extension tubing should be avoided when possible.

Case series have described disruptive histopathologic changes following lidocaine/prilocaine cream anesthetic for biopsies.
A study of histopathologic changes was performed following a randomized trial comparing topical lidocaine/prilocaine cream to 1% lidocaine injection anesthesia for vulvar biopsy. Histopathology was reviewed by two independent dermatopathologists blinded to the type of anesthetic. Specimens were scored on six histopathologic criteria described in the literature. Individual scores for each histopathologic feature and the total score across features were compared between the two groups using marginal models with generalized estimating equations.
Of 37 specimens reviewed, 19 were randomized to lidocaine/prilocaine cream and 18 to 1% lidocaine. Subjects exposed to lidocaine/prilocaine had the following odds of histopathologic changes, relative to lidocaine-exposed subjects acantholysis (odds ratio 2.48; 95% confidence intervals [CI] 0.51, 12.06), clefting (2.42; 0.64, 9.14), pallor/necrosis (1.13; 0.28, 4.50), spongiosis (0.71; 0.18, 2.85), and papillary dermal edema (1.17; 0.41, 3.29). Total scores were not significantly different between treatment arms (risk ratio 0.98; 0.71, 1.35).
This histopathologic analysis of a randomized trial between lidocaine/prilocaine cream and injected lidocaine as anesthesia for vulvar biopsy shows the absence of significant disruptive histopathologic features secondary to the type of anesthetic. Additional studies in different clinical contexts are warranted.

A reduced left ventricular ejection fraction (LVEF) ≤35% ≥6weeks following an acute myocardial infarction (MI) may indicate prophylactic implantation of a cardioverter-defibrillator (ICD). We sought to find predictors of absence of significant left ventricular (LV) remodeling post-MI.
All consecutive patients hospitalized for acute MI with an LVEF ≤35% at discharge in our institution from 2010 were retrospectively included. Patients were assigned to two groups according to the persistence of an LVEF ≤35% (ICD+) or a recovery>35% (ICD-). Logistic regression was performed to build a predictive score, which was then externally validated.
Among a total of 1533 consecutive MI patients, 150 met inclusion criteria, 53 (35%) in the ICD+ group and 97 in the ICD group. After multivariable analyses, an LVEF ≤25% at discharge (adjusted OR 6.23 [2.47 to 17.0], p<.0001) and a CPK peak at the MI acute phase>4600 UI/L (adjusted OR 9.99 [4.27 to 25.3], p<.0001) both independently predicted non-recovery at 6weeks. The IC-D (Increased Cpk-LV Dysfunction) score predicted persistent LVEF ≤35% with areas under curve of 0.83 and 0.73, in the study population and in a multicenter validation cohort of 150 patients, respectively (p<.0001).
The association of a severely reduced LVEF and a major release of myocardial necrosis biomarkers at the acute phase of MI predict unfavorable remodeling, and prophylactic ICD implantation.

Digital clubbing is a well-known clinical sign characterized by thickening of the distal phalanges of the fingers and toes. Unilateral clubbing occurs less frequently. A previous report showed for the first time two cases of unilateral clubbing as a clinical manifestation of lower limb venous malformation. The objective of the present study is to describe a series of 13 patients with a low-flow vascular malformation where a clubbing-like unilateral digital thickening is also observed.
All patients were retrospectively included after reviewing clinical photographs from a vascular malformations database.
A total of 13 patients with low-flow vascular malformations were included in this study. The mean age at diagnosis was 11years (range 5-26years) with a female predominance (nine patients). selleck inhibitor The most frequent vascular malformation collected was a blue rubber bleb nevus syndrome in four patients, followed by common venous malformations in three patients. All patients characteristically exhibited a clubbing-like digital thickening.
