Promotion of physical activity in patients with non-communicable diseases in Luxembourg: a follow-up of the Sport-Sante inventory from 2014.

Regular practice of physical activity (PA) has many health benefits in both healthy individuals and in people with non-communicable diseases (NCDs). In order to disseminate this evidence and to strengthen the promotion of PA in people with NCDs, the Sport-Santé project was created in Luxembourg and officially launched in April 2015. In 2014, a stocktaking of the different organizations offering PA for people with NCDs was realized in order to develop the Sport-Santé project. Different communication tools were used to promote Sport-Santé as well as the aforementioned organizations. The present study aimed to re-evaluate the offers of PA for people with NCDs in Luxembourg one year after the launch of the project. The organizations offering PA for people with NCDs (orthopaedics, obesity and overweight, neurology and rare diseases, oncology and cardiology) were screened in 2014 and in 2016. The number of weekly offered hours of PA for people with NCDs were collected and the participation rate was observed. Participants (192 in 2014 and 196 in 2016) volunteered to answer a survey, which contained questions regarding their age, sex, time since enrolment, travel distance, former and current PA participation, and type of recruitment. Additional items regarding prescription and refund were explored only in 2016. In 2016, more than 55 hours per week of PA were offered for people with NCDs in Luxembourg (≈44 hours per week were identified in 2014). However, this increase was not statistically significant. No difference was observed between 2014 and 2016 regarding the participation rate (2014: 8.9 ± 5.1 participants per hour; 2016: 8.4 ± 5.7 participants per hour). Participants were younger in 2016 than in 2014. The time since enrolment was shorter in 2016 than in 2014. No difference between 2014 and 2016 was observed for travel distance, sex distribution, former and current PA participation, and type of recruitment. Participants were mainly recruited by the healthcare professionals. More than 69 % of the participants would like to receive a medical prescription for the PA. Fifty-two percent of the participants would appreciate a refund of the participation fees by their health insurance. The increasing efforts of Sport-Santé and the organizations offering PA for people with NCDs lead to increase the offer. However, the participation rate remains unchanged. The decrease in age and in time since enrolment observed in 2016 could be explained by the creation of new activities, a larger participant's turnover or high number of withdrawals among long-term participants. Even if participants are mainly recruited by healthcare professionals, this type of recruitment can be attributed to very few idealists. All healthcare professionals should be aware of the offers of Sport-Santé and advise their patients to participate in a PA program. It is now time to advance the idea of prescription of PA as a privileged treatment option and to convince the policymakers to take action against sedentary behaviours in Luxembourg. Nevertheless, this type of promotion is not enough to increase the number of participants and additional strategies must be explored and developed. The best sustainable strategies are always those that approach the problem from different viewpoints.

[Ultrasound guidance for placement control of central venous catheterization. Survey of 802 anesthesia departments for 2007 in Germany]. / Ultraschall und Lagekontrolle bei der Anlage zentraler Venenkatheter. Umfrage unter 802 Anästhesieabteilungen im Jahr 2007 in Deutschland.

OBJECTIVES AND METHODS: In 2007 a survey on the development of the current practice of using ultrasound to assist central venous catheter (CVC) placement was carried out in 802 departments of anesthesiology and intensive care medicine in hospitals with more than 200 beds in Germany. These data were compared to data from a survey in 2003. Additionally, data regarding control of CVC positioning were collected. RESULTS: The response rate was 58%. In these 468 departments approximately 340,000 CVCs are placed annually and 317 departments have access to an ultrasound machine. Ultrasound guidance is used by 188 (40%) departments for central venous cannulation. Of these only 24 (12.7%) use ultrasound routinely and 114 (60.6%) use it when faced with a difficult cannulation. Approximately one-third of the users perform continuous ultrasound guidance for CVC placement. Equipment was not at disposal in 115 (41.1%) departments not using ultrasound for CVC placement did not possess the equipment and 93 (33.2%) did not consider ultrasound necessary. Positioning of CVCs was controlled either by electrocardiogram (ECG) guidance and/or chest radiograph in 92%. CONCLUSION: In Germany placement of central venous catheters is still usually based on anatomical landmarks. However, compared to 2003, ultrasound guidance for CVC placement is gradually being introduced (40% compared to 19%). Given the well-documented advantages of ultrasound guidance compared to landmark based approaches for central venous cannulation, acquisition of this technology should belong to the training programme of an anesthesiologist.

Longitudinal Analysis of Quality of Life, Clinical, Radiographic, Echocardiographic, and Laboratory Variables in Dogs with Preclinical Myxomatous Mitral Valve Disease Receiving Pimobendan or Placebo: The EPIC Study.

BACKGROUND: Changes in clinical variables associated with the administration of pimobendan to dogs with preclinical myxomatous mitral valve disease (MMVD) and cardiomegaly have not been described. OBJECTIVES: To investigate the effect of pimobendan on clinical variables and the relationship between a change in heart size and the time to congestive heart failure (CHF) or cardiac-related death (CRD) in dogs with MMVD and cardiomegaly. To determine whether pimobendan-treated dogs differ from dogs receiving placebo at onset of CHF. ANIMALS: Three hundred and fifty-four dogs with MMVD and cardiomegaly. MATERIALS AND METHODS: Prospective, blinded study with dogs randomized (ratio 1:1) to pimobendan (0.4-0.6 mg/kg/d) or placebo. Clinical, laboratory, and heart-size variables in both groups were measured and compared at different time points (day 35 and onset of CHF) and over the study duration. Relationships between short-term changes in echocardiographic variables and time to CHF or CRD were explored. RESULTS: At day 35, heart size had reduced in the pimobendan group: median change in (Δ) LVIDDN -0.06 (IQR: -0.15 to +0.02), P < 0.0001, and LA:Ao -0.08 (IQR: -0.23 to +0.03), P < 0.0001. Reduction in heart size was associated with increased time to CHF or CRD. Hazard ratio for a 0.1 increase in ΔLVIDDN was 1.26, P = 0.0003. Hazard ratio for a 0.1 increase in ΔLA:Ao was 1.14, P = 0.0002. At onset of CHF, groups were similar. CONCLUSIONS AND CLINICAL IMPORTANCE: Pimobendan treatment reduces heart size. Reduced heart size is associated with improved outcome. At the onset of CHF, dogs treated with pimobendan were indistinguishable from those receiving placebo.

[Cutaneous manifestation of late-type syphilis]. / Hautmanifestation bei Spätsyphilis.

HISTORY AND CLINICAL FINDINGS: A 49-year-old, otherwise healthy man presented at his dermatologist with tuberous skin changes that had be present for several weeks on head, arm and leg. These were asymptomatic, but disturbed him cosmetically. A skin biopsy was performed. INVESTIGATIONS: The skin biopsy showed a granulomatous inflammation with prominent plasma cells, consistent with granulomatous infiltrate. Serologic tests confirmed a Treponema pallidum-infection. In addition, the patient was tested positive for hepatitis C and HIV (CDC stage A1). The clinical neurological examination did not show any pathological findings, however, analysis of the cerebrospinal fluid revealed a mild pleocytosis, elevation of protein and the glucose quotient and a normal Treponema pallidum TPPA-antibody index. A mesaortitis was excluded. THERAPY AND COURSE: We diagnosed a tertiary syphilis (stage III). The patient refused prolonged inpatient treatment with penicillin G i.v., as recommended as first-line therapy in the national guidelines for asymptomatic neurosyphilis. Therefore, after a single oral administration of 100 mg prednisolone he received ceftriaxone intravenously for 14 days. The skin changes resolved. With regard to the HIV infection anti-retro-viral therapy was not yet indicated. CONCLUSIONS: In view of the increasing incidence of syphilis in Germany clinicians should consider this diagnosis when confronted with oligosymptomatic skin lesions.

[Flagellate dermatitis after bleomycin chemotherapy in a patient with malignant germ cell tumor]. / Flagellanten-Dermatitis nach Bleomycingabe bei einem Patienten mit malignem Keimzelltumor.

HISTORY AND CLINICAL FINDINGS: A 49-year-old patient with malignant germ cell tumor within the first cycle PEB (platinum [P], etoposid [E] and bleomycin [B]) presented with an itchy linear papular erythema with discrete vesicles. The rash had appeared three days ago i. e. four days after the second application of bleomycin. INVESTIGATIONS: Visual diagnosis of a flagellate dermatitis. TREATMENT AND CLINICAL COURSE: Primary treatment consisted of systemic antihistamines, local and systemic application of steroids. Bleomycin treatment was stopped and substituted by ifosfamide. CONCLUSION: Flagellate dermatitis occurs with an incidence up to 66 % after bleomycin treatment. There is no association between bleomycin dose and incidence or severity of the lesions. Flagellate dermatitis is a self-limiting condition but hyperpigmentation may persist. Similar lesions may occur with bendamustine and docetaxel, the intake of insufficiently cooked shiitake mushrooms as well as in dermatomyositis and Still's syndrome.

Risk of extravasation after power injection of contrast media via the proximal port of multilumen central venous catheters: case report and review of the literature.

PURPOSE: Multilumen central venous catheters (CVCs) are not commonly used for power injection. However, in critically ill patients, CVCs-- most of which do not have FDA approval for power injection--may be the only available venous access. MATERIALS AND METHODS: The pitfalls of multilumen CVCs are illustrated by a case report of a patient in whom extravasation of intravenously administered contrast medium occurred after power injection in a triple-lumen CVC using the lumen with the port furthest from the catheter tip. RESULTS: The underlying mechanisms for the displacement of the initially correctly placed right subclavian CVC could include elevation of both arms of the obese patient or the power injection itself. The distances between port openings and catheter tips of various commercially available multilumen CVCs are assessed. We examine the possible caveats of ECG-guided CVC placement for optimal tip position, discuss technical difficulties related to power injection via CVCs, and review commonly used drugs that may cause extravasation injury. CONCLUSION: Knowledge of the distances between CVC port openings and the catheter tip are essential for safe intravasal administration of fluids.

Detection of tracheal malpositioning of nasogastric tubes using endotracheal cuff pressure measurement.

BACKGROUND: Insertion of a gastric tube (GT) in anaesthetized, paralyzed and intubated patients may be difficult. Tracheobronchial malposition of a GT may result in deleterious consequences. The purpose of this study was to determine the reliability of tracheal cuff pressure measurement to detect endobronchial malposition of GTs. We compared this new method with the measurement of exhaled CO(2) through the GT. METHODS: Thirty patients under general anesthesia and orotracheal intubation were analysed. First, the cuff pressure of the low-volume endotracheal tube (ET; ID 7.0-8.5 mm) was increased to 40 cmH(2)O. Then, in a randomized fashion, the GT (18 Charrière) was inserted consecutively into the trachea and oesophagus or vice versa. Cuff pressure was monitored continuously while advancing the GT. Furthermore, a capnograph was connected to the gastric tube and the aspirated PCO(2) was monitored. RESULTS: Advancement of the gastric tube into the oesophagus increased ET cuff pressure by 1 +/- 1 cmH(2)O, while endotracheal placement of the GT increased cuff pressure by 28 +/- 8 cmH(2)O (P < 0.001). Using an increase of >10 cmH(2)O in cuff pressure detected endotracheal malpositioning of the GT with 100% sensitivity and specificity. In 28 out of 30 cases, PCO(2) increased by more than 2.6 kPa. Thus, the PCO(2) approach failed to detect tracheal malpositioning in two cases resulting in a sensitivity of 93.3%. CONCLUSIONS: In intubated patients, cuff pressure measurement during insertion of a gastric tube is a new, simple and reliable bedside method to detect endotracheal malpositioning of a GT.

[Tracheal agenesis. A rare cause of respiratory insufficiency in neonates]. / Trachealagenesie. Eine seltene Ursache der respiratorischen Insuffizienz des Neugeborenen.

Tracheal agenesis is a very rare congenital anomaly that occurs isolated or in combination with other anomalies. It presents immediately after birth with an absolute respiratory insufficiency and lack of crying. The immediate precise anatomical classification of the anomaly is crucial in order to decide if surgical therapy is possible. This report describes a newborn boy with tracheal agenesis type II. The diagnosis was confirmed by spiral computed tomography and a selection of the pictures is presented. The treatment was discontinued due to a lack of therapeutical options. Based on this case report we discuss the special situation of this rare anomaly. Interesting information on tracheal agenesis was gathered, the differential diagnosis of respiratory insufficiency of the newborn is summarised and a modified algorithm of the current newborn resuscitation guidelines of the American Heart Association is presented.

[Modified ECG-guidance for optimal central venous catheter tip positioning. A transesophageal echocardiography controlled study]. / Optimierte Positionierung zentraler Venenkatheter durch eine modifizierte Anwendung der intravasalen Elektrokardiographie. Validierung mithilfe der transösophagealen Echokardiographie.

BACKGROUND: Intraatrial electrocardiography (ECG) is a well-established method for central-venous catheter (CVC) placement and an intraatrial position is assumed, when a significantly increased P-wave is registered. However, an increase in P-wave amplitude also occurs in other positions. Therefore we evaluated CVC tip positioning by means of transesophageal echocardiography (TEE) at a maximum P-wave amplitude. PATIENTS AND METHODS: In this prospective randomized study the right or left internal jugular vein was cannulated with 100 patients in each group and catheter tip positioning was guided by means of ECG. The catheter was fixed at the position of maximum P-wave amplitude and the insertion depth was registered. The relationship of the CVC tip position to the superior edge of the crista terminalis was demonstrated with the help of TEE. RESULTS: In all patients the catheter tip was found +/- 0.5 cm from the superior edge of the crista terminalis at the transition from the superior vena cava to the right atrium. On x-ray control, all catheters ran along the length of the vessel wall of the superior vena cava. CONCLUSIONS: A maximum P-wave is derived even at the entrance to the right atrium. This explains why ECG-guided CVC placement -- based on the largest P-wave amplitude -- consistently resulted in correct positioning of the CVC tip at the transition from the superior vena cava to the right atrium.

[Extravasal position of central venous catheters despite unsuspicious ECG-guidance]. / Extravasale Lage von zentralen Venenkathetern bei korrekter EKG-Ableitung.

OBJECTIVE: Does the electrocardiographic method for central venous catheter positioning distinguish between a correct intravasal and a malpositioned extravasal position? METHODS: 24 cardiac surgical patients were enrolled in this prospective observational study. In 18 patients the left, in another 6 patients the right internal jugular vein was cannulated. Using a J-wire within a triple-lumen catheter the amplitude of the P-wave was measured at 3 different intravasal sites: Intra-1: (intravasal baseline electrocardiogram), i. e. 10 cm marking of the catheter on skin level; Intra-2: clear rise of the P-wave amplitude upon further insertion of the catheter; Intra-3: maximum P-wave amplitude. At this position the control of the catheter tip was achieved by means of transoesophageal echocardiography (TOE). Intraoperatively, another J-wire within a triple-lumen catheter was placed by the heart surgeon on 3 extravasal sites and the ECG was recorded: Extra-1: extravasal at the left innominate vein above the pericardial reflection; Extra-2: extravasal on the superior vena cava below the pericardial reflection; Extra-A: extravasal on ascending aorta below the pericardial reflection. The catheter was suture fixed with its tip in position Intra-3. Post surgery a chest radiograph was taken. RESULTS: All catheter tips were visualised at the basis of the Crista terminals (border between right atrium and superior vena cava) by TOE control. The rise of the P wave amplitude at Intra-2, Extra-2 and Extra-A was highly significant compared to the base line at Intra-1 (Intra-1/Intra-2, Intra-1/Extra-2, Intra-1/Extra-A: p in each case < 0.001). The P wave amplitudes of the corresponding intra- and extravasal positions of the left innominate vein (Intra-1/Extra-1, n = 18, p = 0.096)) as well as those of the superior vena cava (Intra-2/Extra-2, n = 24, p = 0.859) did not differ. CONCLUSION: The electrocardiographic method can not differentiate between intra- and extravasal position of a central venous catheter, and thus, presumably fails to identify malpositioning as a result of vascular perforation.

ECG recording of central venous catheter misplaced in inferior thyroid artery.

A 71-year-old male patient with liver metastases secondary to rectal carcinoma was scheduled for hemi-hepatectomy. Two months earlier he had undergone subtotal resection of the thyroid gland. Prior to surgery, a triple-lumen catheter and an introducer sheath were introduced into the right internal jugular vein using a landmark technique. No problems occurred during insertion of the triple-lumen catheter, but resistance was noticed during insertion of the 8.5 FG introducer sheath. After placement of the introducer sheath, intra-arterial misplacement was confirmed using a pressure transducer. The opportunity was taken to record and compare intravascular ECG by the arterial and venous catheters before removal. No difference was noticed in the P-wave patterns; both showed a marked increase. Surgical exploration of the neck, recommended by the vascular surgeon consulted, showed that the carotid artery was not injured. The introducer sheath had completely punctured the right internal jugular vein and entered the inferior thyroid artery. A thrill was felt. The management of this case is discussed, with suggestions for best practice. Intravascular ECG was unhelpful in differentiating between venous and arterial placement of the catheter.

The influence of the Univent endotracheal tube on internal jugular vein cannulation.

This prospective clinical investigation assessed the effect of placement of a Univent tube on the anatomy of the internal jugular veins and the success of cannulation of the left internal jugular vein. After obtaining informed consent, 48 adult patients were enrolled. Of these, 42 patients were eligible and were divided into two groups: Univent tube (group U, n=21) and wire enforced endotracheal tube (group C, n=21). The Univent tube group were having a left thoracotomy. Using horizontal ultrasound scans just above the thyroid gland, the internal jugular vein was visualized and measured before and after Univent placement. The number of needle passes necessary to cannulate the left internal jugular vein in the two groups was also compared. Univent tubes were associated with lateral displacement of the right carotid artery and internal jugular vein on the convex side of the Univent tube, with compression of the right internal jugular vein by the artery, resulting in a kidney-shaped cross-section of the vein. On the left (concave side of the tube), the neck was indented, the sheath of the left carotid artery was displaced medially, and the left internal jugular vein distorted to an ellipse. There was a significant increase in the lateral diameter and a decrease in the cross-sectional area of the left internal jugular vein (t-test, P < 0.05). The first attempt at cannulation of the left internal jugular vein failed significantly more often in the Univent group (13/21 vs 5/21 in group C, Chi-square 6.22, P=0.025). Cannulation of the internal jugular vein before placement of the Univent tube, or placement with ultrasound guidance is suggested.

[Uncorrected transposition of the great arteries and large ventricular septum defect perioperative management of a caesarean section]. / Unkorrigierte Transposition der grossen Arterien und grosser Ventrikelseptumdefekt. Perioperatives Management einer Sectio caesarea.

Patients with congenital cyanotic heart disease are a challenge to the anaesthetist due to the individual haemodynamic characteristics. Maintaining a balance between systemic and pulmonary-vascular resistance is crucial. Here we outline the successful perioperative management of a 24-year-old female with uncorrected transposition of the great arteries (D-TGA) and large septal defect of the ventricle (functionally single ventricle). She was transferred to our perinatologic centre in the 32nd week of pregnancy with symptoms of increasing cardial insufficiency. The peripartum management was agreed upon at an interdisciplinary conference and caesarean section was performed in the 35th week of pregnancy with epidural anaesthesia and no significant problems. Due to hypercoagulability and the risk of "paradoxical" embolism, low molecular weight heparin was given for 6 weeks post partum. The infant was underweight and was admitted to the neonatal intensive care unit, where she made a satisfactory progress.

[Perforation of the superior vena cava due to unrecognized stenosis. Case report of a lethal complication of central venous catheterization]. / Perforation der V. cava superior bei unerkannter Stenose. Fallbericht einer letalen Komplikation einer zentralvenösen Katheterisierung.

We report on a case of fatal perforation of the superior vena cava. The perforation occurred after catheterization of the left internal jugular vein with a hemodialysis catheter, due to an unrecognised stenosis of the superior vena cava. Vascular trauma induced by a previous, also left-sided, subclavian vein-hemodialysis catheter (in place for 14 days), seemed to be the most likely pathomechanism of the stenotic lesion. It should be emphasised that this is a frequent complication especially of left-sided dialysis catheters. In the case described a stenosis was complicated by a misdirected second hemodialysis catheter. Although being repositioned under fluoroscopic control via a guide wire, an extravasal placement occurred but was unrecognised. In order to rule out catheter misplacement, the position of every central venous catheter has to be controlled. Standard methods are either chest X-ray or right atrial electrocardiography. Additionally, confirmation of correct intravenous placement requires a combination of free venous backflow of all lumen and/or blood gas analysis or venous pressure monitoring. Only a combination of tests gives ample certainty as each test for itself has its pitfalls. After placement of hemodialysis catheters, in particular left-sided catheters, we demand chest X-ray in order to verify that the catheter runs parallel with the long axis of the superior vena cava. In doubtful cases the threshold for contrast-enhanced angiographic control of the catheter should be low. If a perforation by the catheter is suspected it should be ruled out by computed tomographic scanning or transesophageal echocardiography.

[Differential diagnosis of left-sided thoracic venous catheters: case report of a persistent left superior vena cava]. / Differenzialdiagnose linksthorakaler Venenkatheter am Beispiel einer persistierenden linken oberen Hohlvene.

The differential diagnosis of left-sided thoracic central venous catheters is discussed in context with the cannulation of a persistent left superior vena cava. In this case the catheter tip was seen lying to the left of the spine on frontal chest X-ray. In addition to the descending aorta, differential diagnoses are a persistent left-sided superior vena cava as well as other smaller veins such as the left internal thoracic vein, the left superior intercostal vein, or the pericardiophrenic vein. The misplacement of a venous catheter in a pericardiophrenic vein may result in a fatal pericardial tamponade.

[Chylothorax after central venous catheterization. Considerations to anatomy, differential diagnosis and therapy]. / Chylothorax nach Anlage eines zentralvenösen Katheters. Uberlegungen zu Anatomie, Differentialdiagnose und Therapie.

The authors report on a chylothorax, a rare, although classical complication of left internal jugular vein cannulation. The anatomy of major lymphatic vessels including variations is illustrated. The mechanisms of central venous catheter associated chylothorax are discussed. Likewise described are pathophysiology, signs, clinical features, and differential diagnosis with special consideration of the triglyceride content as well as treatment options.

Persistent left superior vena cava and central venous catheter position: clinical impact illustrated by four cases.

Variations in the course of the blood vessels are often incidental findings during clinical examination. A persistent left superior vena cava (LSVC) is really not rare (healthy individuals, 0.3-0.5%; patients with congenital heart disease, 4%) and serious complications have been described during catheterization in adults with LSVC (shock, cardiac arrest, angina). Therefore variations of the superior vena cava should be considered, especially when central venous catheterization via the subclavian or internal jugular vein is difficult. We describe the embryogenesis and the anatomic variations of persistent LSVC. Subsequently we suggest a classification of superior vena cava according to the positioning of a central venous catheter on the chest radiograph: type I, normal anatomy; type II, only persistent left superior vena cava; type IIIa, right and left superior vena cava with connection; type IIIb, right and left superior vena cava without connection. This classification is illustrated by four clinical cases.
