A swollen face and neck after dental surgery: Think of subcutaneous emphysema and pneumomediastinum.

Pneumomediastinum and subcutaneous emphysema are defined as the pathological presence of free air in the mediastinum or subcutaneous tissue, respectively. In the majority of cases, pneumomediastinum is secondary to an iatrogenic cause, but has rarely been described after a routine dental extraction. This condition is generally self-limiting, but major complications can occur, such as mediastinitis, which is more frequently associated with iatrogenic pneumomediastinum.

Heart failure with preserved ejection fraction: relevance of a dedicated dyspnoea clinic.

Background And Aims: Heart failure with preserved ejection fraction (HFpEF) is a syndrome with a heterogeneous presentation. This study provides an in-;depth description of haemodynamic and metabolic alterations revealed by systematic assessment through cardiopulmonary exercise testing combined with exercise echocardiography (CPETecho) within a dedicated dyspnoea clinic.

Methods And Results: Consecutive patients (n = 297), referred to a dedicated dyspnoea clinic using a standardized workup including CPETecho, with HFpEF diagnosed through a H2FPEF score ≥6 or HFA-PEFF score ≥5, were evaluated.

The effect of nicotine patches on craving in the brain: A functional MRI study on heavy smokers.

Background: Smoking is a common phenomenon and kills over 6 million people every year. Many smokers try to quit smoking by using nicotine replacement therapy (NRT). Most of the time, relapse occurs in less than six months after finishing the program of NRT.

Orthopnea and pulmonary hypertension. Treat the underlying disease.

We report the case of a patient with longstanding dyspnea upon reclining, who presented with severe right heart failure due to chronic alveolar hypoventilation. Bilateral diaphragmatic paresis was discovered. She recovered from her right ventricular failure with non-invasive mechanical ventilatory support.

Factors determining altered perfusion after acute pulmonary embolism assessed by quantified single-photon emission computed tomography-perfusion scan.

Aim Of The Study: The aim of the study was to analyze the evolution of perfusion (Q)-defects in patients treated for acute pulmonary embolism (PE), correlation with baseline parameters and evaluation of recurrence risk.

Methods: This is a single-center prospective observational cohort study in symptomatic normotensive PE. Comparison of the ventilation/perfusion single-photon emission computed tomography (V/Q-SPECT) acquired at baseline with a quantified SPECT (Q-SPECT) repeated at 1 week and 6 months.

The tension between cross-border cooperation in the European Area of Freedom, Security and Justice and the fundamental rights of mentally ill offenders in detention.

In two recent judgements, the European Court of Human Rights (ECtHR) has given an alarming signal regarding the placement, care and treatment of mentally disordered offenders in Belgium. This article analyses these judgements and the Court's assessment that Belgium faces a structural problem regarding the detention of people with a mental illness in prison. By exploring other recent ECtHR decisions across the EU and combining this with an analysis of international norms and standards, it contends that there is something amiss regarding the post-trial approach towards mentally disordered offenders in an EU-wide context.

Comparison of ventilation-perfusion single-photon emission computed tomography (V/Q SPECT) versus dual-energy CT perfusion and angiography (DECT) after 6 months of pulmonary embolism (PE) treatment.

Background: The natural evolution of treated symptomatic pulmonary embolism shows often incomplete resolution of pulmonary thrombi. The prevalence of perfusion defects depend on the image modality used. This study directly compares V/Q SPECT with DECT.

Protecting the fair trial rights of mentally disordered defendants in criminal proceedings: Exploring the need for further EU action.

Using the new legal basis provided by the Lisbon Treaty, the Council of the European Union has endorsed the 2009 Procedural Roadmap for strengthening the procedural rights of suspected or accused persons in criminal proceedings. This Roadmap has so far resulted in six measures from which specific procedural minimum standards have been and will be adopted or negotiated. So far, only Measure E directly touches on the specific issue of vulnerable persons.

Phase II study of stereotactic body radiotherapy to primary tumor and metastatic locations in oligometastatic nonsmall-cell lung cancer patients.

Background: Stereotactic body radiotherapy (SBRT) has emerged as a treatment modality in patients presenting with oligometastatic nonsmall-cell lung cancer (NSCLC). SBRT is used as a local consolidative treatment to metastatic disease sites. The majority of patients included in SBRT trials for oligometastatic NSCLC have controlled primary tumors and brain metastases.

Severe right heart failure in a patient with chronic obstructive lung disease: a diagnostic challenge.

A 55-year-old male was admitted for evaluation of severe dyspnoea and hypoxaemia. Physical examination upon admission showed elevated jugular venous pressure and an accentuated second heart sound. Chest radiograph showed cardiomegaly with increased bibasilar markings.

Use of likelihood ratios improves interpretation of laboratory testing for pulmonary sarcoidosis.

Laboratory tests for pulmonary sarcoidosis (percentage lymphocytes and CD4/CD8 ratio in bronchoalveolar lavage fluid and serum angiotensin-converting enzyme activity) lack sensitivity and specificity. In a retrospective study of 153 subjects under suspicion of pulmonary sarcoidosis (36 cases and 117 patients with other diseases [control patients]), we defined likelihood ratios (LRs) for rationally selected result intervals of these tests, which improve clinical interpretation as compared with dichotomous interpretation based on a single cutoff value. By using logistic regression analysis, we further integrated the 3 individual tests into a unified algorithm that could rule out diagnosis in 57 (48.

Genetic variation in three candidate genes and nicotine dependence, withdrawal and smoking cessation in hospitalized patients.

Aims: This study evaluates the relationship of six polymorphisms found in the CHRNA3, DRD2 and COMT genes with nicotine dependence, the ability to quit smoking and the occurrence of withdrawal symptoms after short-term use of nicotine patch in hospitalized patients.

Materials & Methods: The study included 233 participants from a double-blind, placebo-controlled trial of nicotine patch substitution with a 6-month follow-up period. Nicotine dependence was assessed by the Fagerström Test for Nicotine Dependence (FTND) questionnaire, withdrawal symptoms by the Minnesota Nicotine Withdrawal Scale questionnaire and smoking cessation by self-reported abstinence at 1 week, 1 month and 6 months after treatment.

Detecting upper airway obstruction in patients with tracheal stenosis.

We propose a forced oscillation test modality for detecting upper airway obstruction (UAO) as an alternative to spirometric UAO indices in patients with tracheal stenosis. From oscillometry performed at different breathing flow rates, airway resistance at 5 Hz was determined at 0.5 l/s (R), and flow dependence of resistance was computed as the regression slope of resistance vs.

A not so healthy muesli: a case report.

We present a patient with severe anaphylaxis, angioedema, hypotension and shock. The near fatal allergic reaction was caused by eating yogurt with muesli containing pine nuts. The patient developed an acute infero-posterolateral myocardial infarction due to systemic hypotension and shock.

Final overall results of a study with a novel triplet induction chemotherapy regimen (PACCAGE) followed by consolidation radiotherapy in locally advanced inoperable non-small cell lung cancer (NSCLC).

Introduction: We report the long term and overall results of a triplet induction chemotherapy regimen followed by standard radiotherapy in patients with locally advanced inoperable stage III non-small cell lung cancer.

Methods: Three cycles of paclitaxel, carboplatin, and gemcitabine were administered every 3 weeks before standard fractionated consolidation radiotherapy starting at least 4 weeks after the last chemotherapy administration. Toxicity and antitumor response was assessed in detail as well as the progression free and overall survival.

Complete metabolic tumour response, assessed by 18-fluorodeoxyglucose positron emission tomography (18FDG-PET), after induction chemotherapy predicts a favourable outcome in patients with locally advanced non-small cell lung cancer (NSCLC).

Background: 18FDG-PET and multislice computerized axial tomography (CT) scan are used for diagnosis, staging and response evaluation in NSCLC patients. The correlation between the response assessment by both imaging techniques and survival was assessed in patients with unresectable stage III NSCLC treated with induction chemotherapy followed by consolidation radiotherapy.

Methods: Thirty-one patients, enrolled in a phase II study evaluating the efficacy and toxicity of a novel triplet induction chemotherapy (paclitaxel, carboplatin and gemcitabine) (PACCAGE) before consolidation radiotherapy, were evaluated by CT and 18FDG-PET at baseline and after three cycles of chemotherapy.

Primary tracheobronchial amyloidosis: a series of 3 cases.

Primary tracheobronchial amyloidosis is a form of localized pulmonary amyloidosis, characterised by the deposition of AL-amyloid in trachea and bronchi. It is a rare and slowly progressive disease, usually requiring repeated endoscopic treatment. In this case series we describe symptoms, diagnostic and therapeutic procedures, radiological findings and pulmonary function testing in 3 cases of different presentation and severity.

A novel triplet regimen with paclitaxel, carboplatin and gemcitabine (PACCAGE) as induction chemotherapy for locally advanced unresectable non small cell lung cancer (NSCLC).

Unlabelled: Phase II study of 3 cycles of triplet induction chemotherapy (response, toxicity) followed by radiotherapy in locally advanced non small cell lung cancer (NSCLC).

Background: Patients with locally advanced inoperable non-small cell lung cancer are currently treated with concomitant or sequential chemotherapy and radiotherapy. However, the outcome of existing treatment modalities is unsatisfactory.

Successful treatment of a giant emphysematous bulla by bronchoscopic placement of endobronchial valves.

Surgical bullectomy is the treatment of choice for giant emphysematous bulla. We report a case of successful nonsurgical treatment with bronchoscopic placement of one-way endobronchial valves that are currently under investigation for the treatment of end-stage emphysema. In patients who are poor surgical candidates, this noninvasive bronchoscopic treatment may represent a valuable alternative.

Small airway function improvement after smoking cessation in smokers without airway obstruction.

Objective: Studying smokers with normal spirometry requires monitoring tools of the peripheral lung. A validated multiple breath washout technique was used to assess possible recovery of smoking-induced small airway malfunction in acinar and conductive lung zones.

Methods: Eighty-seven smokers with a smoking history of at least 10 pack-years but absence of spirometric airflow obstruction were invited for assessment of lung function and small airway function at baseline and after 1 wk, 3 mo, 6 mo, and 12 mo of smoking cessation.

Stenting allows weaning and extubation in ventilator- or tracheostomy dependency secondary to benign airway disease.

Central airway obstruction can cause severe respiratory insufficiency leading to mechanical ventilation (MV) or artificial airway (AA) dependency. Interventional bronchoscopic procedures have been reported to be of help in weaning patients with malignant airway stenoses from mechanical ventilation, whereas their use in benign disease is only anecdotal. The objectives of this study are to evaluate early, intermediate and long-term outcome of interventional bronchoscopy and stent placement in the treatment of MV/AA dependency due to benign airway obstruction.

Fluorescein-enhanced autofluorescence thoracoscopy in patients with primary spontaneous pneumothorax and normal subjects.

Rationale: The exact site(s) and pathophysiology of air leakage in patients with primary spontaneous pneumothorax (PSP) are unknown. In one patient with PSP, fluorescein-enhanced autofluorescence thoracoscopy (FEAT) has shown areas of parenchymal abnormality unnoticed during white light thoracoscopy (WLT).

Objectives: To prospectively perform and compare WLT and FEAT in patients with spontaneous pneumothorax and in normal subjects.
