Speech prognosis and need of pharyngeal flap for non syndromic vs syndromic Pierre Robin Sequence

BACKGROUND: The aim of this retrospective study was to evaluate speech outcome and need of a pharyngeal flap in children born with nonsyndromic Pierre Robin Sequence (nsPRS) vs syndromic Pierre Robin Sequence (sPRS). METHODS: Pierre Robin Sequence was diagnosed when the triad microretrognathia, glossoptosis, and cleft palate were present. Children were classified at birth in 3 categories depending on respiratory and feeding problems. The Borel-Maisonny classification was used to score the velopharyngeal insufficiency. RESULTS: The study was based on 38 children followed from 1985 to 2006. For the 25 nsPRS, 9 (36%) pharyngeal flaps were performed with improvements of the phonatory score in the 3 categories. For the 13 sPRS, 3 (23%) pharyngeal flaps were performed with an improvement of the phonatory scores in the 3 children. There was no statistical difference between the nsPRS and sPRS groups (P = .3) even if we compared the children in the 3 categories (P = .2). CONCLUSIONS: Children born with nsPRS did not have a better prognosis of speech outcome than children born with sPRS. Respiratory and feeding problems at birth did not seem to be correlated with speech outcome. This is important when informing parents on the prognosis of long-term therapy

Preclinical comparison of mTHPC and verteporfin for intracavitary photodynamic therapy of malignant pleural mesothelioma.

Efficacy and tumour selectivity of photodynamic therapy with two clinically approved sensitizers (mTHPC, verteporfin) were assessed for focal intracavitary photodynamic therapy (PDT) in rodents with malignant pleural mesothelioma (MPM) at recommended drug-light conditions and at escalating sensitizer dosages. MPM tumours were generated in 15 Fischer rats by subpleural mediastinal tumour cell injection followed after 5 days by intracavitary PDT with light delivery monitored by in situ dosimetry. Animals were intravenously sensitized either with mTHPC (0.1 mg/kg, n = 3; 0.2 mg/kg, n = 3) followed after 4 days by illumination with 20 J/cm(2) at 652 nm, or with verteporfin (0.6 mg/kg, n = 3; 1.2 mg/kg, n = 3) followed after 20 min by illumination with 100 J/cm(2) at 689 nm. Three untreated tumour-bearing animals served as controls. Histological evaluation of the treated tumour and of adjacent normal organs was performed 10 days after tumour implantation. The extent of PDT-induced tumour necrosis was compared to the non-necrosed area and expressed in percentage. A locally invasive growing MPM tumour (3.1 +/- 1 mm diameter) without spontaneous necrosis diameter was found in all animals. For both sensitizers, focal intracavitary PDT was well tolerated at drug-light conditions recommended for clinical applications. Mediastinal organs were spared for both sensitizers but verteporfin resulted in a higher extent of tumour necrosis (80%) than mTHPC (50%). Drug dose escalation revealed a higher extent of PDT-related tumour necrosis for both sensitizers (mTHPC 55%, verteporfin 88%), however, verteporfin-PDT was associated with a higher toxicity than mTHPC-PDT.

Imaging and therapy with monoclonal antibodies in non-hematopoietic tumors.

Although radiolabelled monoclonal antibodies are useful in tumor imaging, in our opinion their most important role is in the evaluation of the capacity of newly developed monoclonal antibodies to localize in tumors specifically. Intravenous injections of monoclonal antibody fragments, labelled with beta-emitting radionuclides, can completely eradicate large human colon carcinoma xenografts in nude mice whereas this is not achieved by unconjugated monoclonal antibodies. New strategies are being developed to make radioimmunotherapy applicable to carcinoma patients.

Cardiac re-synchronization therapy in a patient with isolated ventricular non-compaction: a case report.

Isolated ventricular non-compaction (IVNC) is a rare, congenital, unclassified cardiomyopathy characterized by prominent trabecular meshwork and deep recesses. Major clinical manifestations of IVNC are heart failure, atrial and ventricular arrhythmias, and thrombo-embolic events. We describe a case of a 69-year-old woman in whom the diagnosis of IVNC was discovered late, whereas former echocardiographic examinations were considered normal. She was known for systolic left ventricular dysfunction for 3 years and then became symptomatic (NYHA III). In the past, she suffered from multiple episodes of deep vein thrombosis and pulmonary embolism. Electrocardiogram revealed a wide QRS complex, and transthoracic echocardiography showed typical apical thickening of the left and right ventricular myocardial wall with two distinct layers. The ratio of non-compacted to compacted myocardium was >2:1. Cardiac MRI confirmed the echocardiographic images. Cerebral MRI revealed multiple ischaemic sequellae. In view of the persistent refractory, heart failure in medical treatment of patients with classical criteria for cardiac re-synchronization therapy, as well as the ventricular arrhythmias, a biventricular automatic intracardiac defibrillator (biventricular ICD) was implanted. The 2-year follow-up period was characterized by improvement of NYHA functional class from III to I and increasing in left ventricular function. We hereby present a case of IVNC with favourable outcome after biventricular ICD implantation. Cardiac re-synchronization therapy could be considered in the management of this pathology.

Anti-TNF-alpha therapy in patients with chronic non-infectious uveitis: the experience of Jules Gonin Eye Hospital.

BACKGROUND: The purpose of this study is to describe the experience of Jules Gonin Eye Hospital on the long-term outcome of anti-TNF-alpha therapy in chronic non-infectious uveitis. PATIENTS AND METHODS: We identified and followed those patients with chronic non-infectious uveitis who received systemic anti-TNF-alpha therapy. Anti-TNF-alpha therapy was administered when no response had been obtained with classical immunosuppressive therapies or in the presence of severe rheumatoid disease. RESULTS: Fifteen patients (28 eyes), 7 male and 8 female (mean age, 43 years; range: 7 to 70 years) were identified. Diagnoses included HLA-B27-associated anterior uveitis (n = 4), sarcoidosis (n = 2), juvenile idiopathic arthritis (n = 2), idiopathic retinal vasculitis with uveitis (n = 2), pars planitis (n = 2), Adamantiades-Behçet disease (n = 1), birdshot retinochoroidopathy (n = 1), and Crohn's disease (n = 1). Mean duration of ocular disease was 8 years (range: 1 to 29 years). Treatment with infliximab (n = 11), etanercept (n = 2), or adalimumab (n = 2) was initiated. One patient with etanercept was switched to infliximab due to lack of clinical response. Clinical and angiographic regression of uveitis was observed within the first two months of therapy in all patients, and was maintained throughout the entire follow-up period (mean 18 months; range: 3 - 72 months). Recurrence was observed in 3 patients, and resolved after adjustment of therapy. Adverse events were recorded in only one patient (arterial hypotension). CONCLUSIONS: In this series of patients with chronic non-infectious uveitis, anti-TNF-alpha therapy was effective and safe. Further clinical studies are needed to determine an adequate duration of therapy.

Supracricoid partial laryngectomy with cricohyoidoepiglottopexy in patients with radiation therapy failure.

BACKGROUND: To assess functional results, complications, and success of larynx preservation in patients with recurrent squamous cell carcinoma after radiotherapy. METHODS: From a database of 40 patients who underwent supracricoid partial laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP) from June 2001 to April 2006, eight patients were treated previously with radiotherapy due to squamous cell carcinoma of the glottic region and were treated for recurrence at the site of the primary cancer. RESULTS: SCPL with CHEP was performed in six men and two women with a mean age of 67 years due to recurrence and/or persistence at a mean time of 30 months postradiotherapy (in case #8 after concomitant chemoradiotherapy). Bilateral neck dissection at levels II-V was performed in six patients. Only case #8 presented metastasis in one node. In case #5, Delphian node was positive. It was possible to preserve both arytenoids in five cases. Definitive surgical margins were negative. Complications were encountered in seven patients. Follow-up was on average 44 months (range: 20-67 months). Organ preservation in this series was 75%, and local control was 87%. Overall 5-year survival was 50%. CONCLUSIONS: In selected patient with persistence and/or recurrence after radiotherapy due to cancer of the larynx, SCPL with CHEP seems to be feasible with acceptable local control and toxicity. Complications may occur as in previously non-irradiated patients. These complications must be treated conservatively to avoid altering laryngeal function.

Combination therapy with venlafaxine and carbamazepine in depressive patients non-responding to venlafaxine : pharmacokinetic and clinical aspects

Résumé L'antidépresseur chiral venlafaxine (VEN) est à la fois un inhibiteur de la récapture de la sérotonine et de la noradrénaline. Le CYP2D6 et le CYP3A4 contribuent à son métabolisme stéreosélectif. Dix patients génotypés au CYP2D6 et dépressifs (F32x et F33x, ICD-10) ont participé à cette étude ouverte sur les conséquences pharmacocinétiques et pharmacodynamiques d'une « augmentation » avec la carbamazepine chez des non-répondeurs à la venlafaxine. Après une première période de traitement de quatre semaines avec VEN (195 - 52 mg/ jour), le seul patient qui présentait un déficience génétique de CYP2D6 (poor metaboliser), avait les taux plasmatiques de S-VEN et R-VEN les plus élevés, tandis que ceux de R-0-déméthyl-VEN étaient les plus bas dans ce groupe. Comme seulement 4 patients ont été des répondeurs après 4 semaines de traitement, 6 patients ont été inclus dans la deuxième période de traitement combiné VEN et carbamazépine. Cinq patients non-répondeurs ont complété cette deuxième période d'étude de quatre semaines. Chez l'unique non-répondeur au traitement combiné, on pouvait observer à la fin de la période d'étude une diminution importante des deux énantiomères de VEN, 0-desmethy'lvenlafaxine (ODV), N-desmethylvenlafaxine (NDV) et N, 0-didesmethylvenlafaxine (NODV) dans le plasma. Cela suggère un manque de compliance chez ce patient, mais une induction métabolique par la carbamazepine ne peut pas être exclue entièrement. L'administration de la carbamazepine (moyen ± s.d. (range) ; 360 ± 89 (200-400) mg/jour)) pendant quatre semaines n'a pas eu comme résultat une modification significative des concentrations plasmatiques des énantiomères de VEN et de ses métabolites 0- et N-démethylés chez les autres patients. En conclusion, ces observations préliminaires suggèrent qu'une combinaison de VEN et de carbamazepine représente une stratégie intéressante par son efficacité, sa tolérance et l'absence de modifications pharmcocinétiques, mais ces résultats devraient être vérifiés dans une plus grande étude.

Self-reported non-adherence to antiretroviral therapy repeatedly assessed by two questions predicts treatment failure in virologically suppressed patients.

BACKGROUND: The aim of this study was to explore the predictive value of longitudinal self-reported adherence data on viral rebound. METHODS: Individuals in the Swiss HIV Cohort Study on combined antiretroviral therapy (cART) with RNA <50 copies/ml over the previous 3 months and who were interviewed about adherence at least once prior to 1 March 2007 were eligible. Adherence was defined in terms of missed doses of cART (0, 1, 2 or >2) in the previous 28 days. Viral rebound was defined as RNA >500 copies/ml. Cox regression models with time-independent and -dependent covariates were used to evaluate time to viral rebound. RESULTS: A total of 2,664 individuals and 15,530 visits were included. Across all visits, missing doses were reported as follows: 1 dose 14.7%, 2 doses 5.1%, >2 doses 3.8% taking <95% of doses 4.5% and missing > or =2 consecutive doses 3.2%. In total, 308 (11.6%) patients experienced viral rebound. After controlling for confounding variables, self-reported non-adherence remained significantly associated with the rate of occurrence of viral rebound (compared with zero missed doses: 1 dose, hazard ratio [HR] 1.03, 95% confidence interval [CI] 0.72-1.48; 2 doses, HR 2.17, 95% CI 1.46-3.25; >2 doses, HR 3.66, 95% CI 2.50-5.34). Several variables significantly associated with an increased risk of viral rebound irrespective of adherence were identified: being on a protease inhibitor or triple nucleoside regimen (compared with a non-nucleoside reverse transcriptase inhibitor), >5 previous cART regimens, seeing a less-experienced physician, taking co-medication, and a shorter time virally suppressed. CONCLUSIONS: A simple self-report adherence questionnaire repeatedly administered provides a sensitive measure of non-adherence that predicts viral rebound.

Multicenter phase II trial of gefitinib first-line therapy followed by chemotherapy in advanced non-small-cell lung cancer (NSCLC): SAKK protocol 19/03.

BACKGROUND: Gefitinib is active in patients with pretreated non-small-cell lung cancer (NSCLC). We evaluated the activity and toxicity of gefitinib first-line treatment in advanced NSCLC followed by chemotherapy at disease progression. PATIENTS AND METHODS: In all, 63 patients with chemotherapy-naive stage IIIB/IV NSCLC received gefitinib 250 mg/day. At disease progression, gefitinib was replaced by cisplatin 80 mg/m(2) on day 1 and gemcitabine 1250 mg/m(2) on days 1, 8 for up to six 3-week cycles. Primary end point was the disease stabilization rate (DSR) after 12 weeks of gefitinib. RESULTS: After 12 weeks of gefitinib, the DSR was 24% and the response rate (RR) was 8%. Median time to progression (TtP) was 2.5 months and median overall survival (OS) 11.5 months. Never smokers (n = 9) had a DSR of 56% and a median OS of 20.2 months; patients with epidermal growth factor receptor (EGFR) mutation (n = 4) had a DSR of 75% and the median OS was not reached after the follow-up of 21.6 months. In all, 41 patients received chemotherapy with an overall RR of 34%, DSR of 71% and median TtP of 6.7 months. CONCLUSIONS: First-line gefitinib monotherapy led to a DSR of 24% at 12 weeks in an unselected patients population. Never smokers and patients with EGFR mutations tend to have a better outcome; hence, further trials in selected patients are warranted.

Hyperaldostéronisme primaire sur adénome ou hyperplasie de la surrénale: opérer ou non [Primary hyperaldosteronism with adrenal adenoma or hyperplasia: surgical case or not?].

Primary hyperaldosteronism is one of the most frequent causes of secondary hypertension. Cardiovascular morbimortality is higher than in essential hypertonic and justifies diagnostic and specific treatment of this pathology. Therapeutic choice depends of health and desire of the patient. It is either medical with mineralocorticoid receptor antagonists, or surgical through adrenalectomy. In this case, a pre-surgery exam including a radiologic examination and a venous adrenal catheterism has to be done. Surgery allows a normalisation of kaliema and a blood pressure decrease in 50 to 88% of the patients. Beyond them, 30% are able to stop entirely their medication. Both therapeutic choices decrease cardiovascular risks equally if blood pressure is controlled.

Isolated limb perfusion with tumor necrosis factor and melphalan for non-resectable soft tissue sarcomas: long-term results on efficacy and limb salvage in a selected group of patients

Background And Objectives: Isolated limb perfusion with TNF-alpha and melphalan (TM-ILP) is a limb salvage therapy for non-resectable soft tissue sarcomas (STS) of the extremities. It is indicated for patients for whom amputation or debilitating surgery is the only alternative. It can be used either as an exclusive therapy (in palliation) or as a neo-adjuvant treatment, followed by marginal resection of tumor remnants with minimal functional impairment. Methods: Between February 1992 and March 2006, 57 TM-ILPs were performed on 51 patients with 88% high grade and 84% advanced stage tumors. Results: Mean follow-up is 38.9 months (4-159, median 22 months). Twenty-one percent patients had significant early complications, with 3 major re-operations, and 23% suffered long-lasting complications. Complete response was observed in 25%, partial response in 42%, stable disease in 14% and progressive disease in 14%. Resection of the tumor remnants was possible in 65%. A complementary treatment was necessary in 31%, mostly radiation therapy. A local recurrence was observed in 35%, after a mean of 20.3 months (2-78), and distant relapse was seen in 45%, after a mean of 13.4 months (5-196). Mean Disease-free survival was 14.9 months, and overall 5-year-survival 43.5%. Amputation rate at 5 years was 24%. Conclusions: TM-ILP is a conservative treatment with a high complications rate, but it can be successful even for the most severe STS of extremities. As a consequence the limb can be spared from amputation or debilitating surgery on the long term in about 75% of patients

Mediastinal reinforcement after induction therapy and pneumonectomy: comparison of intercostal muscle versus diaphragm flaps.

OBJECTIVE: Prospective non-randomised comparison of full-thickness pedicled diaphragm flap with intercostal muscle flap in terms of morbidity and efficiency for bronchial stump coverage after induction therapy followed by pneumonectomy for non-small cell lung cancer (NSCLC). METHODS: Between 1996 and 1998, a consecutive series of 26 patients underwent pneumonectomy following induction therapy. Half of the patients underwent mediastinal reinforcement by use of a pedicled intercostal muscle flap (IF) and half of the patients by use of a pedicled full-thickness diaphragm muscle flap (DF). Patients in both groups were matched according to age, gender, side of pneumonectomy and stage of NSCLC. Postoperative morbidity and mortality were recorded. Six months follow-up including physical examination and pulmonary function testing was performed to examine the incidence of bronchial stump fistulae, gastro-esophageal disorders or chest wall complaints. RESULTS: There was no 30-day mortality in both groups. Complications were observed in one of 13 patients after IF and five of 13 after DF including pneumonia in two (one IF and one DF), visceral herniations in three (DF) and bronchopleural fistula in one patient (DF). There were no symptoms of gastro-esophageal reflux disease (GERD). Postoperative pulmonary function testing revealed no significant differences between the two groups. CONCLUSIONS: Pedicled intercostal and diaphragmatic muscle flaps are both valuable and effective tools for prophylactic mediastinal reinforcement following induction therapy and pneumonectomy. In our series of patients, IF seemed to be associated with a smaller operation-related morbidity than DF, although the difference was not significant. Pedicled full-thickness diaphragmatic flaps may be indicated after induction therapy and extended pneumonectomy with pericardial resection in order to cover the stump and close the pericardial defect since they do not adversely influence pulmonary function.

Peri-operative management of antiplatelet therapy in patients with coronary artery disease. Joint position paper by members of the working group on Perioperative Haemostasis of the Society on Thrombosis and Haemostasis Research (GTH), the working group on Perioperative Coagulation of the Austrian Society for Anesthesiology, Resuscitation and Intensive Care (ÖGARI) and the Working Group Thrombosis of the European Society for Cardiology (ESC).

An increasing number of patients suffering from cardiovascular disease, especially coronary artery disease (CAD), are treated with aspirin and/or clopidogrel for the prevention of major adverse events. Unfortunately, there are no specific, widely accepted recommendations for the perioperative management of patients receiving antiplatelet therapy. Therefore, members of the Perioperative Haemostasis Group of the Society on Thrombosis and Haemostasis Research (GTH), the Perioperative Coagulation Group of the Austrian Society for Anesthesiology, Reanimation and Intensive Care (ÖGARI) and the Working Group Thrombosis of the European Society of Cardiology (ESC) have created this consensus position paper to provide clear recommendations on the perioperative use of anti-platelet agents (specifically with semi-urgent and urgent surgery), strongly supporting a multidisciplinary approach to optimize the treatment of individual patients with coronary artery disease who need major cardiac and non-cardiac surgery. With planned surgery, drug eluting stents (DES) should not be used unless surgery can be delayed for ≥12 months after DES implantation. If surgery cannot be delayed, surgical revascularisation, bare-metal stents or pure balloon angioplasty should be considered. During ongoing antiplatelet therapy, elective surgery should be delayed for the recommended duration of treatment. In patients with semi-urgent surgery, the decision to prematurely stop one or both antiplatelet agents (at least 5 days pre-operatively) has to be taken after multidisciplinary consultation, evaluating the individual thrombotic and bleeding risk. Urgently needed surgery has to take place under full antiplatelet therapy despite the increased bleeding risk. A multidisciplinary approach for optimal antithrombotic and haemostatic patient management is thus mandatory.
