Young Adults at Risk for Excess Alcohol Consumption Are Often Not Asked or Counseled About Drinking Alcohol

Background  

Excessive alcohol consumption is most widespread among young adults. Practice guidelines recommend screening and physician advice, which could help address this common cause of injury and premature death.     

Prevention of contrast‐induced acute kidney injury in patients with stable chronic renal disease undergoing elective percutaneous coronary and peripheral interventions: Randomized comparison of two preventive strategies

Objective : We compared use of intravenous (IV) normal saline (NS) to sodium bicarbonate (NaHCO₃) with or without oral N‐acetylcysteine (NAC) for prevention of contrast‐induced acute kidney injury (CI‐AKI). Background : CI‐AKI is associated with significant adverse clinical events. Use of NAC has produced variable results. Recently, intravenous hydration with NaHCO₃ for CI‐AKI prophylaxis has been adopted as standard treatment for patients with stable chronic renal disease undergoing catheterization procedures. Methods : We prospectively enrolled 320 patients with baseline renal insufficiency scheduled to undergo catheterization. Patients were randomly assigned to receive either IV NS ± NAC (n = 161) or IV dextrose 5% in water containing 154 mEq/l of NaHCO₃ ± NAC (n = 159). IV NS was administered at 1 ml/kg body weight for 12 hr preprocedure and 12 more hr postprocedure. IV NaHCO₃ was administered at 3 ml/kg body weight for 1 hr preprocedure followed by 1 ml/kg body weight postprocedure. A 1,200 mg oral dose of NAC was given 2–12 hr preprocedure and 6–12 hr postprocedure in 50% of patients in each study arm. CI‐AKI was defined as an increase of >0.5 mg/dl or >25% above baseline creatinine. Results : Overall incidence of CI‐AKI was 10.3%. There was no significant difference in incidence among the two groups (NS ± NAC 11.8% vs. NaHCO₃ ± NAC 8.8%, p = ns). Incidence of CI‐AKI increased with increasing age (p = 0.001), contrast agent use >3 ml/kg body weight (p = 0.038) and diuretic use (p = 0.005). Conclusion : Incidence of CI‐AKI was no different in the NaHCO₃ group compared to NS group, and NAC did not reduce CI‐AKI in the two study arms. © 2011 Wiley Periodicals, Inc.     

A Systematic Review of Vinorelbine for the Treatment of Breast Cancer

The purpose of this study was to investigate the efficacy and safety profile of vinorelbine‐based chemotherapy in different settings for the treatment of breast cancer. We performed a computerized search using combinations of the following keywords: “breast cancer”, “breast neoplasms”, “trial”, “vinorelbine” and “navelbine”. A total of 20 trials were included in this analysis, with a total of 5,080 patients accrued. Taxane was associated with enhanced overall survival (OS; p = 0.027) and response rate (RR; p = 0.037) as compared with vinorelbine in monotherapy, but did not show significantly favored progression‐free survival (PFS; p = 0.136). Vinorelbine alone was equivalent to fluoropyrimidine treatment in RR (p = 0.79) for the treatment of metastatic breast cancer. For vinorelbine‐combined regimens, the analysis showed that the vinorelbine group gave similar results as other regimens for OS (p = 0.849) and PFS (p = 0.143). The RR of vinorelbine‐combined regimens was slightly better than that of the other regimens (OR, 1.17), but the difference was not statistically significant. In neoadjuvant setting, vinorelbine treatment was as active as AC (doxorubicin, cyclophosphamide) or DAC (doxorubicin, cyclophosphamide, docetaxel) regimens with respect to RR (p = 0.76) and pathologic complete response (pCR; p = 0.77), but showed lower occurrence of grade 3/4 adverse effects. The analysis also demonstrated that vinorelbine‐containing therapy is effective as adjuvant, front‐line or salvage therapy of metastatic breast cancer, even for patients who were previously treated with anthracyclines or taxanes.     

Foot reconstruction using a serratus anterior muscle flap from the same donor site after failure of a thoracodorsal artery perforator flap

The free flap failure rate for the lower extremities is high, which adversely affects limb salvage efforts. In this article, we report a case of failure of a thoracodorsal artery perforator flap, which was simultaneously reconstructed with a serratus anterior muscle flap from the same donor site. A 56‐year‐old male patient had infected wound for 3 months due to Achilles tendon rupture. We reconstructed the defect using a thoracodorsal artery perforator flap. However, 2 days after the operation, we found the congested flap. We were obliged to discard the whole flap and harvested a serratus anterior muscle flap from the same donor site. The patient's foot healed uneventfully. After flap failure, the use of a second free flap from the same donor site may be an effective and safe procedure in specific cases. © 2013 Wiley Periodicals, Inc.

Does abnormal interhemispheric inhibition play a role in mirror dystonia?

The presence of mirror dystonia (dystonic movement induced by a specific task performed by the unaffected hand) in the dominant hand of writer's cramp patients when the nondominant hand is moved suggests an abnormal interaction between the 2 hemispheres. In this study we compare the level of interhemispheric inhibition (IHI) in 2 groups of patients with writer's cramp, one with the presence of a mirror dystonia and the other without as well as a control group. The level of bidirectional IHI was measured in wrist muscles with dual‐site transcranial magnetic stimulation with a 10‐millisecond (short IHI) and a 40‐millisecond (long IHI) interstimulus interval during rest and while holding a pen in 9 patients with mirror dystonia 7 without mirror dystonia, and 13 controls. The group of patients without mirror dystonia did not differ from the controls in their IHI level. In contrast, IHI was significantly decreased in the group of patients with mirror dystonia in comparison with the group without mirror dystonia and the controls in both wrist muscles of both the dystonic and unaffected hand whatever the resting or active condition (P = 0.001). The decrease of IHI level in the group of patients with mirror dystonia was negatively correlated with the severity and the duration of the disease: the weaker the level of IHI, the more severe was the disease and the longer its duration. Interhemispheric inhibition disturbances are most likely involved in the occurrence of mirror dystonia. This bilateral deficient inhibition further suggests the involvement of the unaffected hemisphere in the pathophysiology of unilateral dystonia. © 2013 International Parkinson and Movement Disorder Society
