Adverse event-related costs for systemic metastatic breast cancer treatment among female Medicaid beneficiaries.

J Med Econ. 2016 Nov;19(11):1027-1033

Authors: Irwin DE, Masaquel A, Johnston S, Barnett B

Abstract
OBJECTIVE: This retrospective study compared the real-world incidence and costs of systemic treatment-related adverse events (AEs) in patients with metastatic breast cancer in a Medicaid population.
METHODS: Insurance claims data for adult women who received biologic or chemotherapy (± hormonal therapy) for metastatic breast cancer between 2006-2013 were extracted from the Truven Health MarketScan(®) Multi-State Medicaid database. Incidence of AEs (per 100 person years) and average monthly AE-related healthcare costs (per-patient-per-month) during each line of therapy (first or later lines) were estimated. The association between AEs and total all-cause healthcare costs was estimated using multivariable regression.
RESULTS: A total of 729 metastatic breast cancer patients were analyzed. Hematological (202.3 per 100 person years) and constitutional AEs (289.6 per 100 person years) were the most common class of AEs reported. Unadjusted per-patient-per-month AE-related expenditure by class were highest for hematological AEs ($1524), followed by gastrointestinal ($839) and constitutional AEs ($795), with anemia ($942), nausea/vomiting ($699), and leukopenia/neutropenia ($550) having incurred the highest total AE-related costs. Adjusted total all-cause monthly costs increased with the number of AEs ($19,701 for >7 AEs, $16,264 for 4 - 6 AEs, and $13,731 for 1 - 3 AEs) compared to no AEs ($5908) (all p < 0.01).
CONCLUSIONS: Among metastatic breast cancer patients treated with systemic therapy in a Medicaid population, AEs were associated with significant increases in costs, which increased with the number of AEs experienced. Therapies associated with a lower incidence of AEs may reduce cost burden and improve patient outcomes.

Clinical pharmacists' opportunities to reduce inappropriate prescription of QT-prolonging medications: calls to action.

Int J Pharm Pract. 2017 Apr;25(2):176-179

Authors: Dhanani TC, Mantovani EH, Turner JR

Abstract
All biologically active agents carry the potential to lead to adverse reactions in certain individuals, including serious cardiac adverse reactions. Since 2005, there has been an international regulatory landscape governing the investigation of a new drug's propensity to lead to the polymorphic ventricular tachycardia Torsades de Pointes (Torsades), a rare but potentially fatal occurrence. When a regulatory agency considers it appropriate, warning information is placed in a medicine's patient information leaflet (label) concerning drug-induced QT interval prolongation, a phenomenon associated with Torsades. In busy hospital settings, however, prescribers, including cardiologists, make injudicious prescribing decisions that put patients at risk. The science of cardiac safety, including the clinical trials that generate the information about QT prolongation in patient information leaflets, is frequently not part of the curriculum at Schools of Pharmacy. Given that medication-induced cardiotoxicity is extremely serious, we advocate that schools integrate the science of cardiac safety into existing therapeutics/therapeutic medication monitoring courses. Given their expert knowledge of pharmacology, pharmacists working as part of a hospital's clinical team would then be even better placed to review prescribing decisions concerning medications that prolong the QT interval, and alert prescribers in cases where reassessing their decisions seems prudent. National pharmacy societies or other pertinent professional societies could create practice guidelines to support graduates once employed as clinical pharmacists. Clinical pharmacists are well placed to be influential arbiters of safer prescribing decisions. Cardiac safety education during their pharmacy training and practice guideline support from professional societies during their careers can optimize this role.

The economic burden of common adverse events associated with metastatic colorectal cancer treatment in the United States.

J Med Econ. 2017 Jan;20(1):54-62

Authors: Latremouille-Viau D, Chang J, Guerin A, Shi S, Wang E, Yu J, Ngai C

Abstract
AIMS: Adverse events (AEs) associated with treatments for metastatic colorectal cancer (mCRC) may compromise the course of treatment, impact quality-of-life, and increase healthcare resource utilization. This study assessed the direct healthcare costs of common AEs among mCRC patients in the US.
METHODS: Adult mCRC patients treated with chemotherapy or targeted therapies were identified from administrative claims databases (2009-2014). Up to the first three mCRC treatment episodes per patient were considered and categorized as with or without the AE system/organ category during the episode. Total healthcare costs (2014 USD) were measured by treatment episode and reported on a monthly basis. Treatment episodes with the AE category were matched by treatment type and line of treatment to those without the AE category. Adjusted total cost differences were estimated by comparing costs during treatment episodes with vs without the AE category using multivariate regression models; p-values were estimated with bootstrap.
RESULTS: A total of 4158 patients with ≥1 mCRC treatment episode were included (mean age = 59 years; 58% male; 60% with liver and 14% with lung metastases; 2,261 [54%] with a second and 1,115 [27%] with a third episode). On average, two treatment episodes were observed per patient with an average length of 166 days per episode. Adjusted monthly total cost difference by AE category included hematologic ($1,480), respiratory ($1,253), endocrine/metabolic ($1,213), central nervous system (CNS; $1,136), and cardiovascular ($1,036; all p < .05).
LIMITATIONS: Claims do not include information on the cause of AEs, and potentially less severe AEs may not have been reported by the physician when billing the medical service. This study aimed to assess the association between costs and AEs and not the causation of AEs by treatment.
CONCLUSIONS: The most costly AEs among mCRC patients were hematologic, followed by respiratory, endocrine/metabolic, CNS, and cardiovascular.

How much information about the benefits of medicines is included in patient leaflets in the European Union? - A survey.

Int J Pharm Pract. 2017 Apr;25(2):147-158

Authors: Dickinson R, Raynor DK, Knapp P, MacDonald J

Abstract
INTRODUCTION: Patient information leaflets (PILs) are required with all licensed medicines throughout the European Union (EU) and they must include information about all side effects and their likelihood. This has led to criticism of a lack of balance, with little information included about potential benefits. Recent European Medicines Agency guidance proposed the inclusion of benefit information, and this study examined the current prevalence and type of such information in PILs in the EU.
METHODS: A survey and content analysis of the English translation of PILs in the EUwas carried out. Random quota sampling was used on the most frequently dispensed (n = 50) and newly licensed medicines (n = 50) in 2011/2. Leaflets were searched for benefit information meeting predefined criteria, and data synthesised and categorised into 10 categories.
RESULTS: Eighty-five (85%) leaflets described how the medicine works, with 45 providing information about the rationale for treatment (more commonly for newly licensed (32/50) than most commonly dispensed medicines (13/50; P < 0.001). Nearly half (47) did not describe whether the medicine was curative, symptomatic or preventative. The terms used to communicate uncertainty were imprecise (such as 'may help'). None communicated numerical benefit information.
CONCLUSION: Current PILs do not appropriately communicate information about benefit. At the basic level, around a half did not include information about treatment rationale or whether the treatment was to treat symptoms, curative or preventative. However, for true informed decision making, patients need quantitative information about benefits and none of the leaflets provided this.

Drug-related problems and medication reviews among old people with dementia.

BMC Pharmacol Toxicol. 2017 Jun 27;18(1):52

Authors: Pfister B, Jonsson J, Gustafsson M

Abstract
BACKGROUND: Drug-related problems, including medication errors and adverse drug events, are common among old people. Due to, for example, greater susceptibility to side effects, people with dementia are even more at risk of drug-related problems. The objectives of this study were to assess the occurrence and character of drug-related problems found among old people with dementia or cognitive impairment.
METHODS: Data from a randomized controlled clinical trial exploring the effects of a pharmacist intervention as part of a hospital ward team in patients 65 years and older with dementia or cognitive impairment were used. The study was conducted between 2012 and 2014 in the orthopedic and medicine wards in two hospitals located in Northern Sweden. Drug-related problems identified in this patient group were classified and described, and associations with different factors were investigated.
RESULTS: Clinical pharmacists identified at least one DRP in 66% (140/212) of participants in the intervention group, for a total of 310 DRPs. Ineffective drug/inappropriate drug and unnecessary drug therapy were the most common drug-related problems. Discontinuation of drug therapy was the most common action carried out. Drug-related problems were more common among people prescribed a larger number of drugs and among people with an earlier stroke.
CONCLUSIONS: Drug-related problems are common among people with dementia and cognitive impairment. Comprehensive medication reviews conducted by clinical pharmacists as part of a health care team might be important to prevent, identify and solve these problems.

Treatment outcomes of fixed-dose combination versus separate tablet regimens in pulmonary tuberculosis patients with or without diabetes in Qatar.

BMC Infect Dis. 2017 Feb 02;17(1):118

Authors: Al-Shaer MH, Mansour H, Elewa H, Salameh P, Iqbal F

Abstract
BACKGROUND: Tuberculosis is considered the second most common cause of death due to infectious agent. The currently preferred regimen for treatment of pulmonary tuberculosis (PTB) is isoniazid, rifampin, pyrazinamide, and ethambutol, which has been used either as separate tablets (ST) or as fixed-dose combination (FDC). To date, no studies have compared both regimens in Qatar. We aim to evaluate the safety and effectiveness of FDC and ST regimen for treating PTB, in addition to comparing safety and efficacy of FDC and ST regimens in patients with diabetes treated for TB.
METHODS: A retrospective observational study was conducted in two general hospitals in Qatar. Patients diagnosed with PTB received anti-tuberculosis medications (either as FDC or ST) administered by the nurse. Sputum smears were tested weekly. We assessed the time to negative sputum smear and incidence of adverse events among FDC and ST groups.
RESULTS: The study included 148 patients. FDC was used in 90 patients (61%). Effectiveness was not different between FDC and ST regimens as shown by mean time to sputum conversion (29.9 ± 18.3 vs. 35.6 ± 23 days, p = 0.12). Similarly, there was no difference in the incidence of adverse events, except for visual one that was higher in ST group. Among the 33 diabetic patients, 19 received the FDC and had faster sputum conversion compared to those who received ST (31 ± 12 vs. 49.4 ± 30.9 days, p = 0.05). Overall, diabetic patients needed longer time for sputum conversion and had more hepatotoxic and gastric adverse events compared to non-diabetics.
CONCLUSION: ST group had higher visual side effects compared to FDC. FDC may be more effective in diabetic patients; however, further studies are required to confirm such finding.

Coupling Data Mining and Laboratory Experiments to Discover Drug Interactions Causing QT Prolongation.

J Am Coll Cardiol. 2016 Oct 18;68(16):1756-1764

Authors: Lorberbaum T, Sampson KJ, Chang JB, Iyer V, Woosley RL, Kass RS, Tatonetti NP

Abstract
BACKGROUND: QT interval-prolonging drug-drug interactions (QT-DDIs) may increase the risk of life-threatening arrhythmia. Despite guidelines for testing from regulatory agencies, these interactions are usually discovered after drugs are marketed and may go undiscovered for years.
OBJECTIVES: Using a combination of adverse event reports, electronic health records (EHR), and laboratory experiments, the goal of this study was to develop a data-driven pipeline for discovering QT-DDIs.
METHODS: 1.8 million adverse event reports were mined for signals indicating a QT-DDI. Using 1.6 million electrocardiogram results from 380,000 patients in our institutional EHR, these putative interactions were either refuted or corroborated. In the laboratory, we used patch-clamp electrophysiology to measure the human ether-à-go-go-related gene (hERG) channel block (the primary mechanism by which drugs prolong the QT interval) to evaluate our top candidate.
RESULTS: Both direct and indirect signals in the adverse event reports provided evidence that the combination of ceftriaxone (a cephalosporin antibiotic) and lansoprazole (a proton-pump inhibitor) will prolong the QT interval. In the EHR, we found that patients taking both ceftriaxone and lansoprazole had significantly longer QTc intervals (up to 12 ms in white men) and were 1.4 times more likely to have a QTc interval above 500 ms. In the laboratory, we found that, in combination and at clinically relevant concentrations, these drugs blocked the hERG channel. As a negative control, we evaluated the combination of lansoprazole and cefuroxime (another cephalosporin), which lacked evidence of an interaction in the adverse event reports. We found no significant effect of this pair in either the EHR or in the electrophysiology experiments. Class effect analyses suggested this interaction was specific to lansoprazole combined with ceftriaxone but not with other cephalosporins.
CONCLUSIONS: Coupling data mining and laboratory experiments is an efficient method for identifying QT-DDIs. Combination therapy of ceftriaxone and lansoprazole is associated with increased risk of acquired long QT syndrome.

Therapeutic efficacy of artemether-lumefantrine for the treatment of uncomplicated Plasmodium falciparum malaria from three highly malarious states in India.

Malar J. 2016 Oct 13;15(1):498

Authors: Bharti PK, Shukla MM, Ringwald P, Krishna S, Singh PP, Yadav A, Mishra S, Gahlot U, Malaiya JP, Kumar A, Prasad S, Baghel P, Singh M, Vadadi J, Singh MP, Bustos MD, Ortega LI, Christophel EM, Kashyotia SS, Sonal GS, Singh N

Abstract
BACKGROUND: Anti-malarial drug resistance continues to be a leading threat to malaria control efforts and calls for continued monitoring of waning efficacy of artemisinin-based combination therapy (ACT). Artesunate + sulfadoxine/pyrimethamine (AS + SP) is used for the treatment of uncomplicated Plasmodium falciparum malaria in India. However, resistance against AS + SP is emerged in northeastern states. Therefore, artemether-lumefantrine (AL) is the recommended first line treatment for falciparum malaria in north eastern states. This study investigates the therapeutic efficacy and safety of AL for the treatment of uncomplicated falciparum malaria in three malaria-endemic states in India. The data generated through this study will benefit the immediate implementation of second-line ACT as and when required.
METHODS: This was a one-arm prospective evaluation of clinical and parasitological responses for uncomplicated falciparum malaria using WHO protocol. Patients diagnosed with uncomplicated mono P. falciparum infection were administered six-dose regimen of AL over 3 days and subsequent follow-up was carried out up to 28 days. Molecular markers msp-1 and msp-2 were used to differentiate recrudescence and re-infection and K13 propeller gene was amplified and sequenced covering the codon 450-680.
RESULTS: A total of 402 eligible patients were enrolled in the study from all four sites. Overall, adequate clinical and parasitological response (ACPR) was 98 % without PCR correction and 99 % with PCR correction. At three study sites, ACPR rates were 100 %, while at Bastar, cure rate was 92.5 % on day 28. No early treatment failure was found. The PCR-corrected endpoint finding confirmed that one late clinical failure (LCF) and two late parasitological failures (LPF) were recrudescences. The PCR corrected cure rate was 96.5 %. The mean fever clearance time was 27.2 h ± 8.2 (24-48 h) and the mean parasite clearance time was 30.1 h ± 11.0 (24-72 h). Additionally, no adverse event was recorded. Analysis of total 186 samples revealed a mutation in the k13 gene along with non-synonymous mutation at codon M579T in three (1.6 %) samples.
CONCLUSION: AL is an efficacious drug for the treatment of uncomplicated falciparum malaria. However, regular monitoring of AL is required in view of malaria elimination initiatives, which will be largely dependent on therapeutic interventions, regular surveillance and targeted vector control.

Metamizole (Dipyrone) as an Alternative Agent in Postoperative Analgesia in Patients with Contraindications for Nonsteroidal Anti-Inflammatory Drugs.

Pain Pract. 2017 Mar;17(3):402-408

Authors: Konijnenbelt-Peters J, van der Heijden C, Ekhart C, Bos J, Bruhn J, Kramers C

Abstract
PURPOSE: Nonsteroidal anti-inflammatory drugs (NSAIDs) play an important role in multimodal pain management. In patients with a contraindication for NSAIDs, pain management is challenging. A recent Dutch anesthesiology guideline propagates the use of metamizole (dipyrone) in these patients. Metamizole is a controversial drug, its use being previously discouraged because of the risk for agranulocytosis. We discuss whether metamizole could be an alternative to classical NSAIDs and opioids in postoperative pain management despite this drawback.
METHOD: Literature review and pharmacovigilance research based on World Health Organization adverse effect registrations.
RESULTS: Metamizole causes fewer gastric and duodenal ulcers than other nonselective NSAIDs, and the risk for bleeding is limited. It is unknown whether it is safer than a nonselective NSAID combined with a proton pump inhibitor. Although the drug appears to be safe for renal function in healthy volunteers, data in high-risk patients (eg, those with heart or renal failure) are lacking. The incidence of metamizole-induced agranulocytosis is controversial, but the risk is likely to be limited with short-term postoperative use in this selected group of patients.
CONCLUSION: Although firm evidence is lacking, metamizole may be safer for the upper intestinal tract and kidneys than other NSAIDs, and could alternatively be used in patients with an increased risk for stomach or renal problems. Hereby, improved postoperative pain relief can potentially be achieved. The risk for metamizole-induced agranulocytosis is judged to be acceptable.

Pharmacological Treatment of Pain in Cancer Patients: The Role of Adjuvant Analgesics, a Systematic Review.

Pain Pract. 2017 Mar;17(3):409-419

Authors: van den Beuken-van Everdingen MH, de Graeff A, Jongen JL, Dijkstra D, Mostovaya I, Vissers KC, national guideline working group “Diagnosis treatment of cancer pain”

Abstract
CONTEXT: In patients with cancer, pain is one of the most feared and burdensome symptoms. Adjuvant analgesics are an important cornerstone on which treatment of pain in patients with cancer is based.
OBJECTIVES: To update our guidelines for the treatment of pain in patients with cancer, we performed a systematic review on the use of adjuvant analgesics in pain in cancer.
METHODS: A systematic search of the literature was performed searching for articles that studied the effect of (1) antidepressants, (2) anti-epileptics, (3) N-methyl-d-aspartate (NMDA) receptor antagonists, and (4) other adjuvant analgesics in patients with cancer pain and described their effects on pain intensity and/or side effects.
RESULTS: Based on the keywords and after reading the full papers, we could include 12 papers on anticonvulsants, 10 papers on antidepressants, four on NMDA receptor antagonists, and 10 papers on other adjuvant analgesics. The methodological quality of the included papers was graded as low to very low. Overall, there was a low quality of evidence that gabapentin, pregabalin, amitriptyline, and venlafaxine were effective in reducing pain intensity in patients with cancer pain. There was insufficient evidence on the effectiveness of lamotrigine, levetiracetam, NMDA antagonists, cannabinoids, corticosteroids, and local anesthetics on reducing pain intensity in patients with cancer pain.
CONCLUSION: The quality of currently available evidence on the effectiveness of adjuvant analgesics in the treatment of cancer pain is low. The treatment of pain associated with cancer should be tailored to the patient's personal preferences.

Ertapenem-Induced Thrombocytosis.

Cureus. 2017 May 19;9(5):e1263

Authors: Docobo RA, Bukhari S, Qutrio Baloch Z

Abstract
Ertapenem is a β-lactam antibiotic that has a broad spectrum of anti-microbial coverage. Hematological adverse events like thrombocytosis, neutropenia, and neutropenia are infrequent. Here we report a rare case of drug-induced thrombocytosis in a 68-year-old female, who was treated with ertapenem for the diagnosis of complicated abdominal infection. This case emphasizes that any patient with thrombocytosis should be assessed with a careful and detailed history with consideration for possible drug side effects.

Age-related trends in injection site reaction incidence induced by the tumor necrosis factor-α (TNF-α) inhibitors etanercept and adalimumab: the Food and Drug Administration adverse event reporting system, 2004-2015.

Int J Med Sci. 2017;14(2):102-109

Authors: Matsui T, Umetsu R, Kato Y, Hane Y, Sasaoka S, Motooka Y, Hatahira H, Abe J, Fukuda A, Naganuma M, Kinosada Y, Nakamura M

Abstract
Tumor necrosis factor-α (TNF-α) inhibitors are increasingly being used as treatment for rheumatoid arthritis (RA). However, the administration of these drugs carries the risk of inducing injection site reaction (ISR). ISR gives rise to patient stress, nervousness, and a decrease in quality of life (QoL). In order to alleviate pain and other symptoms, early countermeasures must be taken against this adverse event. In order to improve understanding of the risk factors contributing to the induction of ISR, we evaluated the association between TNF-α inhibitors and ISR by applying a logistic regression model to age-stratified data obtained from the Food and Drug Administration Adverse Event Reporting System (FAERS) database. The FAERS database contains 7,561,254 reports from January 2004 to December 2015. Adjusted reporting odds ratios (RORs) (95% Confidence Intervals) were obtained for interaction terms for age-stratified groups treated with etanercept (ETN) and adalimumab (ADA). The adjusted RORs for ETN* ≥ 70 and ADA* ≥ 70 groups were the lowest among the age-stratified groups undergoing the respective monotherapies. Furthermore, we found that crude RORs for ETN + methotrexate (MTX) combination therapy and ADA + MTX combination therapy were lower than those for the respective monotherapies. This study was the first to evaluate the relationship between aging and ISR using the FAERS database.

Efficacy and safety of tenofovir disoproxil fumarate in preventing vertical transmission of hepatitis B in pregnancies with high viral load.

Sci Rep. 2017 Jun 23;7(1):4132

Authors: Chen JZ, Liao ZW, Huang FL, Su RK, Wang WB, Cheng XY, Chen JQ, Liu JQ, Huang Z

Abstract
This study was a meta-analysis of the literature on the efficacy and safety of tenofovir disoproxil fumarate (TDF) in preventing vertical transmission of hepatitis B in pregnancies with high viral load. Four observational studies and one randomized controlled trial involving 585 pregnant women and 595 newborns were included in the meta-analysis. TDF was more effective than the placebo in reducing vertical transmission in HBeAg-positive chronic hepatitis B (CHB) pregnancies with high serum HBV-DNA levels (OR = 0.21, 95% CI = 0.07-0.61) at 4-12 months, infant HBV DNA seropositivity at delivery (OR = 0.16, 95% CI = 0.07-0.37), and a severe flair in maternal alanine aminotransferase (ALT) levels (OR = 0.43, 95% CI = 0.19-0.95) during pregnancy. In addition, TDF showed more improvement in HBV DNA suppression at delivery (OR = 254.46, 95% CI = 28.39-2280.79). No significant differences were found in HBeAg seroconversion or ALT normalization; or in rates of cesarean section, emergent cesarean section, postpartum hemorrhage, prematurity, congenital malformations, or infant death. However, TDF induced more drug-related adverse events (OR = 2.33, 95% CI = 1.39-3.89) and elevated creatine kinase (CK) (OR = 9.56, 95% CI = 1.17-78.09) than in controls. The available evidence suggests that TDF is effective and safe in preventing vertical transmission of hepatitis B in pregnancies exhibiting a high viral load.

Oral Cholic Acid is Efficacious and well Tolerated in Patients with Bile Acid Synthesis and Zellweger Spectrum Disorders.

J Pediatr Gastroenterol Nutr. 2017 Jun 21;:

Authors: Heubi JE, Bove KE, Setchell KDR

Abstract
BACKGROUND/AIMS: Patients with bile acid synthesis disorders (BASD) due to single enzyme defects (SED) or Zellweger spectrum disorders (ZSD) accumulate hepatotoxic atypical bile acids resulting in potentially fatal progressive liver disease. We evaluated the efficacy and safety of oral cholic acid in patients with BASD.
METHODS: In this phase 3, open-label, single-arm, nonrandomized, noncomparative study conducted over 18 years, patients were administered cholic acid orally 10 to 15 mg/kg/day. The primary efficacy variables were changes from pre- to post-treatment in atypical urinary bile acids, liver chemistries (serum aspartate aminotransferase [AST], alanine aminotransferase [ALT]), and height and weight. Additional efficacy variables included changes in serum bilirubin and liver histology.
RESULTS: Of 85 enrolled patients (63 with SED and 22 with ZSD), 79 received at least 1 dose of study medication; 70 patients (50 with SED and 20 with ZSD) were included in the modified intent-to-treat dataset. Cholic acid significantly improved urine bile acid metabolite scores (P < 0.0001) and serum AST and ALT (P < 0.0001) in patients with SED and ZSD. Cholic acid also improved height and weight percentiles in both groups, but only the change in weight was significant (P < 0.05). Serum direct bilirubin decreased significantly post-treatment (P < 0.001) in the ITT population, and liver biopsies showed either stable findings or histologic improvement in all parameters except bridging fibrosis. The overall safety profile of cholic acid was favorable, with no study drug-related serious adverse events or drug-related deaths reported.
CONCLUSION: Oral cholic acid is a safe, efficacious, and well-tolerated treatment for BASD due to SED and ZSD.This is an open access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Dexmedetomidine and general anesthesia: a narrative literature review of its major indications for use in adults undergoing non-cardiac surgery.

Minerva Anestesiol. 2017 Jun 22;:

Authors: Davy A, Fessler J, Fischler M, le Guen M

Abstract
BACKGROUND: In Europe, dexmedetomidine has marketing approval only for sedation in intensive care units. However, its use during general anesthesia has been widely reported. The aim of this narrative review is to draw a picture of potential indications in anesthesia.
METHODS: We searched in MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials using the keywords "Dexmedetomidine, Dexdor, Precedex and Dexdomitor". The research ended in December 2016. Studies were eligible for inclusion they reported the use of dexmedetomidine in adults receiving general anesthesia. We excluded studies related to cardiac surgery and studies reporting the use of dexmedetomidine as an adjuvant of locoregional anesthesia.
RESULTS: Several potential uses for dexmedetomidine during general anesthesia are described, especially: awake fiber optic intubation, the sparing effect of dexmedetomidine on hypnotic and opioid drugs, prevention of postoperative pain, nausea and vomiting and shivering, improvement of postoperative sleep and postoperative recovery, opioid-free anesthesia, use in craniotomy, endovascular stroke treatment and drug-induced sleep endoscopy. A protective effect against cardiac complications, an anti-inflammatory effect, and side effects, particularly bradycardia, are also described.
CONCLUSIONS: The properties of dexmedetomidine lead to its use for elective indications such as awake fiberoptic intubation and neurosurgical anesthesia. New topics are under debate. These subjects must be studied thoroughly because of their implication in the patients' surgical course. These advantages must be weighed against the major drawback of dexmedetomidine administration which is the potential for hemodynamic abnormalities.

[Clinical aspects of treatment with amiodarone].

Herzschrittmacherther Elektrophysiol. 2017 Jun 22;:

Authors: Haverkamp W, Israel C, Parwani A

Abstract
Amiodarone has multiple and complex electrophysiological effects that render it a very effective antiarrhythmic drug for the treatment of both, supraventricular and ventricular arrhythmias. Proarrhythmic effects of amiodarone in patients with structural heart disease are rare. However, extracardiac adverse effects occurring in association with amiodarone treatment are frequent and feared. These adverse effects have usually been related to total amiodarone exposure (i. e., dose and duration of treatment). Parallel to a more frequent use of lower amiodarone maintenance doses (100-200 mg/day), the incidence of severe unwanted extracardiac side effects has decreased. High-dose maintenance regiments (daily dose ≥300 mg) are usually obsolete. This paper discusses recommendations regarding the monitoring of cardiac and extracardiac side effects of amiodarone. They need to be regarded by physicians using amiodarone to ensure long-term safety of amiodarone therapy.

Combined data of intravaginal prasterone against vulvovaginal atrophy of menopause.

Menopause. 2017 Jun 19;:

Authors: Labrie F, Archer DF, Martel C, Vaillancourt M, Montesino M

Abstract
OBJECTIVE: To analyze the effects of intravaginal prasterone obtained in the three randomized clinical studies performed in postmenopausal women suffering from moderate to severe (MS) dyspareunia due to vulvovaginal atrophy (VVA).
METHODS: In three independent 12-week prospective, randomized, double-blind, and placebo-controlled clinical studies, the effect of daily intravaginal 0.50% (6.5 mg) prasterone was examined on four co-primary objectives in women having MS pain during sexual activity (dyspareunia), identified as their most bothersome symptom (MBS) of VVA at baseline.
RESULTS: In 436 women treated with 0.50% prasterone and 260 women who received placebo, an average 35.1% decrease over placebo in the percentage of parabasal cells (P < 0.0001), an average 7.7% increase in the percentage of superficial cells (P < 0.0001), and a mean 0.72 pH unit decrease in vaginal pH (P < 0.0001) were observed. The severity score of most bothersome symptom dyspareunia was decreased by a 0.46 unit (49%) (P < 0.0001 over placebo), whereas the severity score of MS vaginal dryness decreased by 0.31 unit (P < 0.0001 over placebo). A very positive evaluation was obtained on the acceptability of the technique of administration of the insert, whereas the male partners reported a very positive evaluation of the changes observed in their sexual partner.
CONCLUSION: The efficacy data demonstrate highly positive effects on all the symptoms and signs of vulvovaginal atrophy with no significant drug-related side effects in line with the physiology of menopause and intracrinology.

Abstract
BACKGROUND: In many malaria-endemic, sub-Saharan African countries, existing pharmacovigilance systems are not sufficiently operational to document reliably the safety profile of anti-malarial drugs. This study describes the implantation of a community-based pharmacovigilance system in Côte d'Ivoire and its use to document the safety of ASAQ Winthrop(®) (artesunate-amodiaquine).
METHODS: This prospective, longitudinal, descriptive, non-comparative, non-interventional study on the use of artesunate-amodiaquine in real-life conditions of use was conducted in seven Community Health Centres of the Agboville district in Côte d'Ivoire. Twenty trained Health Centre employees and 70 trained community health workers were involved in data collection in the field. All patients with suspected uncomplicated falciparum malaria, seeking treatment at one of the participating Health Centres, and treated with artesunate-amodiaquine could be enrolled. Two visits were planned, one for inclusion at the Health Centre and a second at home, performed by a community health worker 3-10 days after the inclusion visit. Administration of artesunate-amodiaquine was unsupervised. Adverse events (AEs) were documented at the home visit or during any unexpected visit to the Health Centre or to the hospital and coded and adjudicated by a local pharmacovigilance committee. Symptoms suggestive of hepatic failure, severe neutropaenia, extrapyramidal disorders and retinopathy were considered a priori as AEs of special interest.
RESULTS: Some 15,228 malaria episodes in 12,198 patients were evaluated; 2545 AEs were documented during 1978 malaria episodes (13.0%). The most frequently observed events were asthenia (682 cases), vomiting (482 cases) and somnolence (174 cases). Most reported AEs were of mild or moderate intensity and resolved without corrective treatment. One-hundred and five (105) AEs reported during 100 episodes (0.7%) were considered as serious. Three serious cases of transient extrapyramidal disorders, identified as AEs of special interest were reported in three patients.
CONCLUSION: The fixed dose artesunate-amodiaquine combination ASAQ Winthrop(®) for the unsupervised treatment of uncomplicated falciparum malaria under real-life conditions of care in Côte d'Ivoire is well tolerated. The study emphasizes the interest of involving properly trained community health workers to collect pharmacovigilance data in the field in order to document rare AEs.
