Abstract
We report the results of short-term tamoxifen treatment (20 mg two times a day orally) in 2 patients with metastatic medullary thyroid carcinoma. Patient A had a rapid tumor progression with development of Cushing's syndrome before initiation of tamoxifen treatment. Patient B had a slowly progressive course. In both cases, neither clinical nor biochemical improvement were observed, after 1 and 3 months of tamoxifen therapy, respectively.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) continues to be a major public health problem. Vancomycin and teicoplanin have been in clinical use for several decades but their drawbacks are well described. In the last 10 years, several antibiotics have been made available for clinical use. Daptomycin and linezolid have been extensively used during this period. Other agents such as ceftaroline, ceftobiprole, dalbavancin, oritavancin, tedizolid and telavancin have been approved by regulatory agencies since 2009. Many others, such as the newer tetracyclines, fluoroquinolones, oxazolidinones and pleuromutilins, are in various stages of development. In addition, an ongoing multicentre trial is investigating the role of combination of vancomycin or daptomycin with β-lactam antibiotics. This review discusses the role of the newer antibiotics, reflecting the views of the 6th MRSA Consensus Conference meeting of the International Society of Chemotherapy MRSA Working Group that took place in 2016.

Abstract
This review is the result of discussions that took place at the 5th MRSA Working Group Consensus Meeting and explores the possible treatment options available for different types of infections due to methicillin-resistant Staphylococcus aureus (MRSA), focusing on those antibiotics that could represent a valid alternative to vancomycin. In fact, whilst vancomycin remains a viable option, its therapy is moving towards individualised dosing. Other drugs, such as the new lipoglycopeptides (oritavancin, dalbavancin and telavancin) and fifth-generation cephalosporins (ceftaroline and ceftobiprole), are showing good in vitro potency and in vivo efficacy, especially for patients infected with micro-organisms with higher vancomycin minimum inhibitory concentrations (MICs). Tedizolid is an attractive agent for use both in hospital and community settings, but the post-marketing data will better clarify its potential. Daptomycin and linezolid have shown non-inferiority to vancomycin in the treatment of MRSA bacteraemia and non-inferiority/superiority to vancomycin in the treatment of hospital-acquired pneumonia. Thus, several options are available, but more data from clinical practice, especially for invasive infections, are needed to assign specific roles to each antibiotic and to definitely include them in the new antibacterial armamentarium.

Abstract
Although the rapid spread of carbapenemase-producing Gram-negatives (CPGNs) is providing the scientific community with a great deal of information about the molecular epidemiology of these enzymes and their genetic background, data on how to treat multidrug-resistant or extended drug-resistant carbapenemase-producing Enterobacteriaceae and how to contain their spread are still surprisingly limited, in spite of the rapidly increasing prevalence of these organisms and of their isolation from patients suffering from life-threatening infections. Limited clinical experience and several in vitro synergy studies seem to support the view that antibiotic combinations should be preferred to monotherapies. But, in light of the data available to date, it is currently impossible to quantify the real advantage of drug combinations in the treatment of these infections. Comprehensive clinical studies of the main therapeutic options, broken down by pathogen, enzyme and clinical syndrome, are definitely lacking and, as carbapenemases keep spreading, are urgently needed. This spread is unveiling the substantial unpreparedness of European public health structures to face this worrisome emergency, although experiences from different countries-chiefly Greece and Israel-have shown that CPGN transmission and cross-infection can cause a substantial threat to the healthcare system. This unpreparedness also affects the treatment of individual patients and infection control policies, with dramatic scarcities of both therapeutic options and infection control measures. Although correct implementation of such measures is presumably cumbersome and expensive, the huge clinical and public health problems related to CPGN transmission, alongside the current scarcity of therapeutic options, seem to fully justify this choice.

Abstract
Patients with fever and granulocytopenia are at risk of developing severe infection. We performed a prospective, randomized trial to evaluate the efficacy of low-dose cefepime plus amikacin (C-A) compared to low-dose piperacillin/tazobactam plus amikacin (PT-A). Patients received cefepime (2 g/12 h) plus amikacin (15 mg/kg/day) or piperacillin/tazobactam (4 g/500 mg/8 h) plus amikacin. A total of 317 episodes of febrile granulocytopenia in 190 patients were studied (152 in the C-A group, 165 in the PT-A group). A microbiologically documented infection was present in 53 (35%) episodes in the C-A group and 41 (25%) episodes in the PT-A group (p = ns); a clinically documented infection was observed in 39 (26%) and 47 (28%) episodes, respectively. Toxicity was observed in 6 (4%) episodes in the C-A group and in 5 (3%) episodes in the PT-A group. The antibiotic success rate (no change or addition of antibiotics) was recorded in 89 (59%) and 105 (64%) cases, respectively (p = ns). Mortality related to infection was similar in each arm (3.9% vs. 3.6%). Combination therapy of low-dose beta-lactam with an aminoglycoside achieves very good response rates and low rates of toxicity. It might be an attractive option in an environment of increasing resistance among gram-negative bacteria.

Abstract
The purpose of the study was to compare the clinical characteristics and outcomes of bacteraemic pneumococcal pneumonia (BPP) in chronic obstructive pulmonary disease (COPD) and non-COPD patients. A case-control study was conducted. Cases were any adult with BPP and forced expiratory volume in 1 second (FEV(1)) <80% and FEV(1)/forced expiratory vital capacity (FVC) <70%. Controls were patients with BPP without clinical diagnosis of COPD matched 1:2 by age, gender and date of isolation. Variables included co-morbidities, serotypes, pneumonia severity index (PSI), treatment and mortality. There were 45 cases and 90 controls. No significant differences were found in Charlson scores, antibiotic treatment, serotype distribution and severity. Malignancy, shock and mechanical ventilation were less frequent in COPD patients. One patient died vs 14 controls (p = 0.02). In univariate analysis, shock, multilobar involvement, Charlson score, heart failure and absence of COPD were associated with mortality. After adjustment for the presence of shock there were no differences in mortality. BPP presents less frequently with shock and has a lower mortality rate in COPD patients than in non-COPD patients.

Abstract
We sought to determine factors associated with opportunistic infections (OI) in infliximab-treated patients. A retrospective study cohort (1999-2004) was examined. Nine OI were diagnosed in 94 infliximab-treated patients: tuberculosis (four), visceral leishmaniasis (one), pyogenic muscular abscess (one Salmonella spp. and one Streptococcus pneumoniae), and two viral infections (hepatitis B virus [HBV] and zoster ophthalmicus). The risk for OI was significantly higher in the first year of treatment (odds ratio [OR] 8; 95% confidence interval [CI] 2-50). Previous treatment with more than two immunosuppressive drugs was the only factor related to OI (OR 8.686; 95% CI 1.889-39.943). We identified the subset of patients treated with infliximab who had a higher risk for OI. The screening of latent infections is key to diminishing the incidence of these infections.

Abstract
OBJECTIVE To study the characteristics of major bleeding episodes into a closed space (BCS) of patients under chronic anticoagulation with either unfractionated heparin (HS) or coumadin (CM), and to determine the relationship, if any, of anticoagulation parameters (INR, PT and PTT) values at the time of bleeding with the episode. Finally, to determine risk factors for BCS and mortality in this population. METHODS Descriptive epidemiology of all cases of BCS seen in our hospital from 1995 to 2000 was obtained through the records and follow up visits of all patients under anticoagulation (HS or CM) during this period. A matched case-control study to determine risk factors for BCS was carried out. Cases and controls (1:2) were matched for age, gender, anticoagulant treatment and indication for anticoagulation. Cases were patients with a BCS while on anticoagulation (HS OR CM). Controls were patients under anticoagulation (HS or CM) without any bleeding episode during the study period that had anticoagulation parameter values (INR, PT or PTT) determined the very same day than the cases. RESULTS During the study period, 225 patients under anticoagulation were prospectively followed (75 cases and 150 controls) amid a total of 1650 patients under anticoagulation, for a 4.5% prevalence of BCS. Reasons for anticoagulation were: atrial fibrillation in 79 (35.3%), valvular heart disease in 59 (25.9%), pulmonary embolism or deep venous thrombosis in 48 (21.4%), dilated cardiomyopathy in 26 (11.6%) and vascular cerebral stroke in 13 (5.8%). Mean age of cases was 70.5 (SD 9.5) years and 41 (55%) were women, values similar to the controls. At the time of BCS 39 patients were on CM and 36 on HS. The mean INR value in the CM group at the time of the episode of BCS was 5.3 (SD + 7.5) while the PTT value was 2,25 (SD 0.95) in the HS group. There was previous antecedent bleeding in 24 (32%) cases. The most common sites of BCS were: muscular (40%), CNS (30.6%), retroperitoneal (18,6%) and articular (10.6%). Muscular (abdominal or thoracic wall) and retroperitoneal BCS were higher in the HS group (10 and 12 in the HS group versus 5 and 2 in the CM group, respectively; p < 0.0001). In contrast, CNS bleeding was commoner in the CM group (20 in CM versus 3 in HS; p < 0.001). BCS related mortality rate was 14.6% (11/75) and higher in the CM group (p = 0.04). Comparative analysis of the case-control study revealed that anticoagulation values in the CM group at the time of bleeding were within the recommended range in 38.5% of cases vs. 75% of the controls (p < 0.001). Also, there were significant differences in mean INR values between cases and controls (5.3 + 7.5 vs. 2.6 + 0.9, p < 0.029) In the HS group no differences were present in PTT values at the time of bleeding between cases and controls. In BCS cases, a previous bleeding episode was more frequent than in the control group (32% versus 1.3%, p < 0.001). Likewise, mortality was higher in cases (18,6%) than in controls (11.4%), p = 0.01. CONCLUSIONS In our study, the majority of patients under anticoagulation with CM had INR values above the recommended range at the time of BCS, in contrast with those on HS that had a PTT within the therapeutic range at the time of the BCS. A previous bleeding episode was an independent risk factor for a BCS episode. Bleeding was a late complication in the CM group and frequently in the CNS, while BCS was more frequently associated with muscular or retroperitoneal sites in the HS treated group. BCS related mortality was 15%. Close monitoring of INR is crucial to minimize bleeding complications.

Abstract
The benefit of systemic steroids as adjunctive treatment in patients with severe community-acquired pneumonia (CAP) remains unclear. The present study aimed to evaluate the impact of corticosteroid treatment on mortality in patients with severe CAP. A retrospective, observational study of a cohort of patients hospitalised with severe CAP, classes IV and V of the Prognostic Severity Index score, was carried out. Information on epidemiological, clinical and laboratory data, and 30-day mortality was collected from medical charts. Of the 308 patients evaluated, 238 (77%) were treated with standard antimicrobial therapy and 70 (23%) received both antibiotics and systemic steroids. Clinical characteristics were similar between steroid and nonsteroid groups, except in the prevalence of male sex and the presence of chronic obstructive pulmonary disease. Systemic steroids were independently associated with a decreased mortality (odds ratio 0.287; 95% confidence interval 0.113-0.732), while severity of CAP (2.923; 1.262-6.770) was the only independent factor associated with increased mortality. Mortality decreased in the patients with severe CAP who received simultaneous administration of systemic steroids along with antibiotic treatment. Severity of community-acquired pneumonia remains the most important risk factor associated with increased mortality.

Abstract
The most common complications after surgical extraction of the third mandibular molar are trismus, oedema or swelling, local pain, dysphagia and infection. The aim of this comparative, double-blind, randomized clinical trial was to evaluate the efficacy of two sustained release amoxicillin/clavulanate regimens in the reduction of infection after third molar extractive surgery. A total of 225 patients were randomized into three equal groups: placebo, prophylaxis with single pre-surgical dose of two tablets amoxicillin/clavulanate 1000/62.5 mg, and pre-emptive post-surgery therapy with two tablets amoxicillin/clavulanate 1000/62.5 mg BID for 5 days. A higher rate of infection (P=0.006) was found among patients receiving placebo (16%) than those receiving single-dose prophylaxis (5.3%) or 5-day pre-emptive therapy (2.7%). A relationship between both the duration (13.8% for long versus 7.4% for medium versus 1.6% for short) and difficulty (12.7% with ostectomy versus 3.5% without ostectomy; P=0.011) of surgical procedure and incidence of subsequent infection was also observed. Both prophylactic and therapeutic regimens versus placebo achieved greater reduction of pain after surgery on day 3 (P=0.001). Logistic regression analysis revealed a risk of infection of 24%, 9% and 4% for ostectomy with placebo, prophylaxis and pre-emptive treatment, respectively, whereas it was 7%, 2% and 1% if ostectomy was not performed. Pre-emptive therapy with the oral sustained release amoxicillin/clavulanate formulation reduced the rate of subsequent infection in patients undergoing ostectomy. Prophylaxis was beneficial in simpler procedures and may be indicated in cases where ostectomy is not performed.

Abstract
This study evaluated the impact of heptavalent pneumococcal conjugate vaccine (HPCV) on invasive pneumococcal disease (IPD) in children aged < or = 5 years in Barcelona, Spain. The incidence of IPD, vaccine uptake and prevalence of nasopharyngeal colonisation were analysed in two different periods: 1999-2001 (pre-licence period), and 2002-2004 (post-licence period). In total, 121 cases of IPD were identified. The overall incidence of IPD decreased from 96.9 cases/100,000 to 90.6 cases/100,000 (OR 0.93, 95% CI 0.69-1.26, p 0.71) between the two periods. The proportion of cases caused by non-vaccine-related serotypes (NVS) increased from 21% to 43.7% (OR 2.9, 95% CI 1.2-7, p 0.01). IPD was diagnosed in seven vaccinated children, six of whom were infected by NVS. There was a trend of diminishing prevalence of resistance to penicillin and macrolides in 2002-2004. The incidence of empyema increased from 1.7 to 8.5/100,000 (OR 4.5, 95% CI 0.91-18, p 0.06). The rate of vaccination ranged from 4.8% to 34%. It was concluded that the rates of IPD in this area did not decrease following the introduction of HPCV. The low uptake of vaccine and the greater proportion of colonisation/infection by NVS probably explain these findings. A trend of increasing empyema was also apparent. A decrease in the prevalence of penicillin and macrolide resistance paralleled the progressive uptake of vaccine.

Abstract
Antibiotic restrictions present difficult choices for physicians, patients and payors. Physicians must choose between the welfare of the patient and the directive of healthcare systems to restrict antibiotics. These may be supported with incentives or penalties, causing a conflict of interest. The patient has an expectation of best care, but will often be unaware of antibiotic restriction policies and is therefore not fully informed about his/her treatment. For payors, reducing the volume of antibiotic prescribing and/or prescribing less expensive antibiotics are apparently attractive targets for cost savings. However, we are only now beginning to understand the downstream consequences of restricting antibiotics on outcomes and costs. We are hampered by the lack of a universal ethical framework and information on outcomes. In addition, the concept of 'effective' or 'best' therapy will vary among different groups. Balancing the risks of treating or not treating with antibiotics is complex. Suboptimal therapy, that fails to eradicate the bacterial infection, exposes the patient to the risk of poor outcome, adverse events and the wider risk of antimicrobial resistance. Failure to treat where the risk of a poor outcome exceeds the risk of an adverse event is also ethically unacceptable. The key to rational antibiotic prescribing is to identify those patients who need antibiotic therapy and optimise therapy to achieve the fastest bacterial and clinical cure. We are only now beginning to assemble the information and tools to be able to make such decisions. Above all, we should treat on the basis of knowledge.

Abstract
Community-acquired pneumonia (CAP) is a common illness associated with high rates of morbidity and mortality worldwide. The beta-lactam antibacterial agents have been the mainstay of therapy for CAP for over four decades and remain as first-line therapy. However, the impact of the substantial prevalence of resistance seen among the common respiratory pathogens, particularly penicillin and macrolide resistance among Streptococcus pneumoniae, is now an area for concern. CAP treatment guidelines often recommend the use of a macrolide or fluoroquinolone in conjunction with, or as an alternative to, beta-lactam agents, but whether this is necessary is uncertain. This review outlines the historical use of beta-lactam antibacterial agents in the treatment of CAP along with their ongoing therapeutic utility.

Abstract
Community acquired pneumonia is still an important health problem. In Spain the year incidence is 162 cases per 100,000 inhabitants with 53,000 hospital admission costing 115 millions of euros per year. In the last years there have been significant advances in the knowledge of: aetiology, diagnostic tools, treatment alternatives and antibiotic resistance. The Spanish Societies of Intensive and Critical Care (SEMICYUC), Infectious Diseases and Clinical Microbiology (SEIMC) and Pulmonology and Thoracic Surgery (SEPAR) have produced these evidence-based Guidelines for the management of community acquired pneumonia in Adults. The main objective is to help physicians to make decisions about this disease. The different points that have been developed are: aetiology, diagnosis, treatment and prevention.

Abstract
Using pharmacokinetic/pharmacodynamic principles, pharmacokinetically enhanced amoxicillin/clavulanate 2000/125 mg twice daily was designed to provide adequate levels of amoxicillin over the 12-h dosing interval to eradicate penicillin-resistant Streptococcus pneumoniae (PRSP, penicillin MICs > or = 2 mg/L) with amoxicillin MICs of at least 4 mg/L. The clinical efficacy of amoxicillin/clavulanate 2000/125 mg was evaluated in patients with respiratory tract infections caused by S. pneumoniae, including isolates with elevated penicillin (2-8 mg/L) MICs. Data from 10 clinical studies were combined: seven randomised (1:1), double-blind, controlled trials (efficacy intent-to-treat [ITT]N = 3376): amoxicillin/clavulanate 2000/125 mg twice daily vs. levofloxacin 500 mg once daily in acute bacterial sinusitis (ABS); levofloxacin 500 mg once daily in acute exacerbations of chronic bronchitis (AECB); clarithromycin 500 mg twice daily in AECB; amoxicillin/clavulanate 875/125 mg twice daily/three times daily and 1000/125 mg three times daily in community-acquired pneumonia (CAP) and three noncomparative studies (efficacy ITT N = 3024): two in ABS, one in CAP. The bacteriological per-protocol (PP) population at follow up (days 14-39) comprised 1295 patients for amoxicillin/clavulanate 2000/125 mg and 241 for comparators. With amoxicillin/clavulanate 2000/125 mg at follow-up, outcome was successful (clinical success and eradication/presumed eradication) in 85/90 (94.4%) patients with S. pneumoniae in comparative studies and 421/445 (94.6%) in noncomparative studies, and with comparators 58/70 (82.9%) were successes. In the amoxicillin/clavulanate 2000/125 mg group at follow up, 52/552 S. pneumoniae isolates were resistant to penicillin. At follow up, 50/52 (96.2%) patients with PRSP were successes, including 6/7 with amoxicillin MICs of 4 mg/L and 7/8 with amoxicillin MICs of 8 mg/L. Success rates for amoxicillin/clavulanate 2000/125 mg against PRSP were similar for CAP (96.0%[24/25]), AECB (100%[3/3]) and ABS (95.8%[23/24]). There were six PRSP isolates in the comparator group (two isolates were from one patient), and three of five patients in this group were successes. In conclusion, amoxicillin/clavulanate 2000/125 mg demonstrated combined clinical/bacteriological success against 50/52 patients with PRSP, including 13/15 strains with amoxicillin MICs of 4-8 mg/L. These results for the pharmacokinetic-enhanced formulation of amoxicillin/clavulanate 2000/125 mg are in line with the high efficacy against PRSP predicted using pharmacokinetic/pharmacodynamic parameters.

Abstract
Macrolide resistance among pneumococci is increasing worldwide and is associated with increasing macrolide use. Recent studies show that use of macrolides and azalides increases nasopharyngeal carriage of both macrolide-resistant and penicillin-resistant pneumococci. Carriage of a resistant pneumococcus may foster dissemination. The clinical relevance of in vitro resistance has been debated. However, recent data from a matched case-control study showed that 18 (24%) of 76 patients had breakthrough bacteraemia with an erythromycin-resistant pneumococcus while taking a macrolide, whereas none of the 136 matched controls with an erythromycin-susceptible pneumococcal bacteraemia was taking a macrolide (P = 0.0000001). Moreover, five (24%) of 21 patients bacteraemic with the low-level resistant M phenotype and none of the 40 matched controls were taking a macrolide (P = 0.00157). These data indicate that macrolide resistance due to both the efflux and the methylase mechanisms is clinically relevant. Furthermore, they favour guidelines for the empirical treatment of outpatients with community-acquired pneumonia that recommend high-dose oral amoxicillin and reserve coverage of atypical pathogens for selected high-risk populations.
