Evidence Associated with the Use of Oxazolidinones for the Treatment of Skin and Skin Structure Infections: A Retrospective Study

INTRODUCTION: Skin and skin structure infections are an increasing cause of hospitalization. Although mortality is relatively low, skin and skin structure infections are associated with prolonged hospital length of stay and high costs. Oxazolidinones have been suggested as a tool to treat infected patients in the ambulatory setting in order to decrease hospital length of stay. We wanted to address the evidence associated with the use of oxazolidinones in the treatment of skin and skin structure infections. MATERIAL AND METHODS: In this observational retrospective study we analyzed the anonymized diagnosis related group coded information from the Portuguese database for hospital admissions, that included all adult patients with a diagnosis of oxazolidinone use and a SSSI, discharged between 2010 and 2015. RESULTS: During the study period, a total of 5518 patients had a diagnosis of oxazolidinone treatment. We selected 483 of those who were also diagnosed with a skin and skin structure infections. Their mean age was 64.9 years and 62.7% were male. The median hospital length of stay was 27 days (Inter quartile range 13 - 56) and the mortality rate was 12.6%. The prevalence of secondary anemia and of thrombocytopenia in the whole group treated with oxazolidinones was 2.5% and 3%, respectively. DISCUSSION: Despite the high bioavailability of oxazolidinones, we were not able to find evidence that its use was associated with a decrease of mortality or hospital length of stay (due to early discharge) of patients with skin and skin structure infections. CONCLUSION: In this study we were not able to find evidence that oxazolidinones had any clinically significant benefit. A structured approach, including antibiotics with favorable pharmacokinetic and safety profile as well as a carefully planned ambulatory follow up may be needed.info:eu-repo/semantics/publishedVersio

Aneurisma Intracraniano na Criança

Os aneurismas cerebrais são raros na criança, embora a sua ruptura seja a principal causa de hemorragia subaracnoideia neste grupo etário. Apresenta-se o caso de uma criança de 11 anos de idade, que recorreu ao hospital por cefaleia súbita e intensa, sem história prévia de traumatismos ou infecções. O estudo clínico e imagiológico realizado foi sugestivo de hemorragia subaracnoideia. A angiografia cerebral permitiu o diagnóstico de aneurisma da bifurcação da artéria carótida interna esquerda. Foi submetida a cirurgia, com boa evolução pós-operatória. Pretende-se com este caso alertar para as dificuldades no diagnóstico diferencial de ruptura de aneurisma cerebral na criança e salientar que um diagnóstico correcto e precoce permite melhorar o prognóstico

Triple POCUS: A New Approach to an Old Problem

Pulmonary embolism (PE) is the most serious and life-threatening clinical presentation of venous thromboembolism, and difficult to diagnose. Triple point-of-care-ultrasonography (POCUS) of the lung, heart and leg veins is a multiorgan approach that may help to evaluate patients suspected of having PE, in combination with existing protocols and computed tomographic pulmonary angiography (CTPA). We present the case of a 26-year-old man with sudden onset of dyspnoea and swelling of the leg with a Well's score of 9. With CTPA unavailable at the time of presentation, triple POCUS showed subpleural consolidations and a venous thrombus in a popliteal vein. A diagnosis of deep vein thrombosis with PE was made and the appropriate treatment was started immediately. Although triple POCUS has less sensitivity and specificity than CTPA, it could be very useful in some clinical settings.info:eu-repo/semantics/publishedVersio

Bilateral knee dislocation with associated bilateral popliteal arterial injury

Tibiofemoral unilateral knee dislocations are uncommon, making bilateral dislocations even rarer injuries. Knee dislocation is considered one of the most serious injuries that can affect this joint. Associated complications such as popliteal artery injury are responsible for the important morbidity in these patients. The authors report the case of a 52-year-old man with a traumatic bilateral knee dislocation with associated bilateral popliteal arterial injury. His clinical presentation along with radiographic and angiographic findings are described. Surgical and non-surgical treatment and functional outcomes are also reported.info:eu-repo/semantics/publishedVersio

Impact of antibiotic therapy in severe community-acquired pneumonia: Data from the Infauci study

Antibiotic therapy (AT) is the cornerstone of the management of severe community-acquired pneumonia (CAP). However, the best treatment strategy is far from being established. To evaluate the impact of different aspects of AT on the outcome of critically ill patients with CAP, we performed a post hoc analysis of all CAP patients enrolled in a prospective, observational, multicentre study. Of the 502 patients included, 76% received combination therapy, mainly a β-lactam with a macrolide (80%). AT was inappropriate in 16% of all microbiologically documented CAP (n=177). Hospital and 6months mortality were 34% and 35%. In adjusted multivariate logistic regression analysis, combination AT with a macrolide was independently associated with a reduction in hospital (OR 0.17, 95%CI 0.06-0.51) and 6months (OR 0.21, 95%CI 0.07-0.57) mortality. Prolonged AT (>7days) was associated with a longer ICU (14 vs. 7days; p7days had no survival benefit and was associated with a longer LOS.info:eu-repo/semantics/publishedVersio

Management of ibrutinib treatment in patients with B-cell malignancies: clinical practice in Portugal and multidisciplinary recommendations

Objectives: Ibrutinib, a potent inhibitor of the Bruton tyrosine kinase, has revolutionized the treatment of many B-cell malignancies. Ibrutinib has an established favorable toxicity profile with up to 8 years of experience in clinical trials; however, despite ibrutinib’s favorable toxicity profile, dose reductions and treatment discontinuations are becoming more evident in clinical practice, particularly in the setting of specific clinical contexts and patient characteristics. This manuscript is set to provide practical recommendations on the management of patients treated with this agent in daily practice. Methods: A group of multidisciplinary experts from Portugal met to discuss and highlight practical recommendations, supported on both literature and clinical insights, for the management of the treatment with ibrutinib. Results/discussion: Handling of both toxicities and drug–drug interactions during ibrutinib treatment poses several challenges to healthcare providers and can benefit from a multidisciplinary approach. The involvement of specialties, such as cardiology, infectiology and pharmacology, can bring an added value to patient care, not only in anticipating/managing safety issues and dose adjustments but also in enhancing adherence to treatment, ultimately improving the risk/benefit balance. Conclusion: By involving a multidisciplinary group of experts, this work provides a set of key recommendations to optimize care and outcomes for ibrutinib-treated patients. Despite not being a fully comprehensive review on the topic, it is intended as a framework to hematologists and other healthcare professionals who manage these patients in their daily clinical practice.The project received financial support from Janssen for logistics of expert meetings and editorial support.

Validação do score de Alvarado no diagnóstico de apendicite aguda em crianças e adolescentes no Hospital de Braga

Introduction: Acute appendicitis (AA) is the leading cause of emergency abdominal surgery in children. The diagnosis is essentially clinical, but some methodologies, such as Alvarado score (AS), have been developed in order to avoid non-therapeutic laparotomy (15-30%). AS = 5 or 6 is compatible with AA and is an indication for the patient to remain on observations, if AS = 7 a laparotomy procedure may be indicated. Objective: To validate the AS for the AA diagnosis of children admitted at Braga Hospital. Methods: A validation study of diagnostic method (AS) using the histological examination as a gold standard. The study population consisted of 192 children (4-17 years) with abdominal pain that underwent appendectomy in the last 20 months (December 2008 to July 2010). It was determined the values of sensitivity (S), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV), likelihood ratio (LR) and the ROC curve for three different cut-off points (SA =5, 6 and 7). Results: We found that as the cut-off point of AS decreases progressively the sensitivity and specificity increases and reduces the VPN and VPP. Assuming a cut-off value of 5, only 18 children would be false negatives, instead of the 67 children if the cut-off point was 7 points. The analysis of ROC curves demonstrated a greater area under the curve for a cut-off equal to or greater than 5 (AUC = 70%). Discussion: We recommend using a cut-off value of 5 points, since only 18 children with AA were initially classified as appendicitis unlikely, this value would increase to 67 patients for the SA value of = 7. The AS is a valuable tool in screening children with abdominal pain for the diagnosis of AA. Nonetheless the diagnosis and final decision must be based on clinical and systematic reassessment of patients
