    Full Text Available Background and Aim: Rigid bronchoscopy is often an indispensable procedure in the therapeutic management of a wide variety of tracheobronchial disorders. However, it is performed at only a few centers in adult patients in India. Herein, we report our initial 1-year experience with this procedure. Materials and Methods: A prospective observational study on the indications, outcomes, and safety of various rigid bronchoscopy procedures performed between November 2009 and October 2010. Improvement in dyspnea, cough, and the overall quality of life was recorded on a visual analog scale from 0 to 100 mm. A systematic review of PubMed was performed to identify studies reporting the use of rigid bronchoscopy from India. Results: Thirty-eight rigid bronchoscopies (50 procedures were performed in 19 patients during the study period. The commonest indication was benign tracheal stenosis followed by central airway tumor, and the procedures performed were rigid bronchoplasty, tumor debulking, and stent placement. The median procedure duration was 45 (range, 30-65 min. There was significant improvement in quality of life associated with therapeutic rigid bronchoscopy. Minor procedural complications were encountered in 18 bronchoscopies, and there was no procedural mortality. The systematic review identified 15 studies, all on the role of rigid bronchoscopy in foreign body removal. Conclusions: Rigid bronchoscopy is a safe and effective modality for treatment of a variety of tracheobronchial disorders. There is a dire need of rigid bronchoscopy training at teaching hospitals in India.

    Lung cancer still represents the leading cause of cancer-related death, and the long-term survival rate remains low. Computed tomography (CT) is currently the most common imaging modality for lung diseases recognition. The purpose of this work was to develop a simple and easily accessible virtual bronchoscopy system to be coupled with a customized electromagnetic (EM) tracking system for navigation in the lung and which requires as little user interaction as possible, while maintaining high usability. The proposed method has been implemented as an extension to the open-source platform, 3D Slicer. It creates a virtual reconstruction of the airways starting from CT images for virtual navigation. It provides tools for pre-procedural planning and virtual navigation, and it has been optimized for use in combination with a [Formula: see text] of freedom EM tracking sensor. Performance of the algorithm has been evaluated in ex vivo and in vivo testing. During ex vivo testing, nine volunteer physicians tested the implemented algorithm to navigate three separate targets placed inside a breathing pig lung model. In general, the system proved easy to use and accurate in replicating the clinical setting and seemed to help choose the correct path without any previous experience or image analysis. Two separate animal studies confirmed technical feasibility and usability of the system. This work describes an easily accessible virtual bronchoscopy system for navigation in the lung. The system provides the user with a complete set of tools that facilitate navigation towards user-selected regions of interest. Results from ex vivo and in vivo studies showed that the system opens the way for potential future work with virtual navigation for safe and reliable airway disease diagnosis.

    Full Text Available Luis M Seijo Pulmonary Department, Instituto de Investigación Sanitaria-Fundación Jimenez Díaz-Centro de Investigación Biomedica en Red Enfermedades Respiratorias, Madrid, Spain Abstract: Electromagnetic navigation bronchoscopy (ENB is one of several technological advances which have broadened the indications for bronchoscopy in the diagnostic workup of lung cancer. The technique facilitates bronchoscopic sampling of peripheral pulmonary nodules as well as mediastinal lymph nodes, although wide availability and expertise in endobronchial ultrasonography has limited its application in routine clinical practice to the former. ENB in this setting is quite versatile and may be considered an established alternative to more invasive techniques, especially in selected patients with underlying pulmonary disease or comorbidities at high risk for complications from computer topography-guided fine needle aspiration or surgical resection. Nodule sampling may be performed with a variety of instruments, including forceps, cytology brushes, and transbronchial needles. Although samples are generally small, they are often suitable for molecular analysis. Keywords: lung cancer, ENB, electromagnetic navigation, bronchoscopy, diagnosis, pulmonary nodule

    The aim of this study was to demonstrate the possibilities, advantages and limitations of virtual bronchoscopy using data sets from positron emission tomography (PET) and computed tomography (CT). Twelve consecutive patients with lung cancer underwent PET/CT. PET was performed with F-18-labelled 2-[fluorine-18]-fluoro-2-deoxy-D-glucose ({sup 18}F-FDG). The tracheobronchial system was segmented with a volume-growing algorithm, using the CT data sets, and visualized with a shaded-surface rendering method. The primary tumours and the lymph node metastases were segmented for virtual CT-bronchoscopy using the CT data set and for virtual PET/CT-bronchoscopy using the PET/CT data set. Virtual CT-bronchoscopy using the low-dose or diagnostic CT facilitates the detection of anatomical/morphological structure changes of the tracheobronchial system. Virtual PET/CT-bronchoscopy was superior to virtual CT-bronchoscopy in the detection of lymph node metastases (P=0.001), because it uses the CT information and the molecular/metabolic information from PET. Virtual PET/CT-bronchoscopy with a transparent colour-coded shaded-surface rendering model is expected to improve the diagnostic accuracy of identification and characterization of malignancies, assessment of tumour staging, differentiation of viable tumour tissue from atelectases and scars, verification of infections, evaluation of therapeutic response and detection of an early stage of recurrence that is not detectable or is misjudged in comparison with virtual CT-bronchoscopy.

    Objective To evaluate the efficacy and safety of percutaneous tracheostomy by means of single-step dilation with fiber optic bronchoscopy assistance in critical care patients under mechanical ventilation. Methods Between the years 2004 and 2014, 512 patients with indication of tracheostomy according to clinical criteria, were prospectively and consecutively included in our study. One-third of them were high-risk patients. Demographic variables, APACHE II score, and days on mechanical ventilation prior to percutaneous tracheostomy were recorded. The efficacy of the procedure was evaluated according to an execution success rate and based on the necessity of switching to an open surgical technique. Safety was evaluated according to post-operative and operative complication rates. Results The mean age of the group was 64 ± 18 years (203 women and 309 males). The mean APACHE II score was 21 ± 3. Patients remained an average of 11 ± 3 days on mechanical ventilation before percutaneous tracheostomy was performed. All procedures were successfully completed without the need to switch to an open surgical technique. Eighteen patients (3.5%) presented procedure complications. Five patients experienced transient desaturation, 4 presented low blood pressure related to sedation, and 9 presented minor bleeding, but none required a transfusion. No serious complications or deaths associated with the procedure were recorded. Eleven patients (2.1%) presented post-operative complications. Seven presented minor and transitory bleeding of the percutaneous tracheostomy stoma, 2 suffered displacement of the tracheostomy cannula, and 2 developed a superficial infection of the stoma. Conclusion Percutaneous tracheostomy using the single-step dilation technique with fiber optic bronchoscopy assistance seems to be effective and safe in critically ill patients under mechanical ventilation when performed by experienced intensive care specialists using a standardized procedure.

    Patients may find bronchoscopy without sedation unpleasant. There is some evidence that patient satisfaction correlates with amnesia for the procedure. For several years we have used doses of midazolam sufficient to put patients lightly asleep hoping to produce complete amnesia. We looked at practical aspects of this technique over a 2-year period. We studied 337 consecutive patients. They were 219 men and 118 women of mean age 63 +/- 12.4 (SD). Sixty-seven patients were aged 75 years or over and the eldest was 86. Sixty-three patients were already hospital inpatients but the remainder were seen as day cases. Midazolam was given by slow i.v. injection over several minutes until the patient was judged to be lightly asleep. Patients were given supplemental oxygen (3 l min-1) and monitored by ECG and pulse oximetry. A note was made of the time at which they awakened, defined as when nursing staff felt the patients were awake enough to have a cup of tea and toast. Patients were asked if they had any memory of the procedure both on awakening and when seen a few days later to discuss the results. The procedures were carried out in a well-staffed Day Case Unit with a recovery area. The mean dose of midazolam used was 10.8 mg (mean +/- SD = 0.16 +/- 0.095 mg kg-1). The midazolam was given over a median of 4 min (range 1-15 min). Patients took 59 +/- 45 min (mean +/- SD) to wake up. Twenty-eight patients were given flumazanil to reverse the sedation (11 for concern over bleeding following biopsies, three for desaturation during and three after procedure, four as they were frail, two as they were restless, two as they were hypotensive after procedure and three for miscellaneous reasons). Only nine patients could remember any part of the procedure. Incremental doses of midazolam given slowly until patients are lightly asleep almost invariably produce complete amnesia for bronchoscopy. This is a safe technique but patients need careful monitoring and may require reversal of

    Full Text Available Objective: Fiberoptic bronchoscopy (FOB is the most frequently used tool for invasive pulmonary evaluation with high diagnostic yield and low incidence of major complications. These advantages led to increasing use of FOB in intensive care units. In this article, we discussed our experiences of FOB applications in mechanical ventilated critically ill patients. Materials and Methods: We investigated FOB procedures of 118 patients on mechanical ventilation for respiratory failure in intensive care unit retrospectively. All patients’ demographic data, indications, complications and arterial blood gas analyses belong to before and after bronchoscopy were evaluated. Results: FOB indications of the patients were 55.1% for mucoid plug clearance, 9.3% for treatment of atelectasia, 7.6% for identifying hemorrhagic foci, 17.8% for tracheostomy management, 6.8% for bronchoalveolar lavage and 3.4% for exploratory purposes. Overall complication rate of FOB was 11.9%. Arterial blood gas analyses statistically improved after FOB. Conclusion: In this study, we observed that FOB is being performed with many different indications and acceptable complication rates in our intensive care unit and also contributes to diagnose and treatment of intensive care patients.

    Full Text Available OBJECTIVE: To evaluate the importance of flexible bronchoscopy in tracheostomy patients in the process of decannulation to assess the incidence and types of laryngotracheal injury and compare the presence of such lesions with clinical criteria used for decannulation. METHODS: We studied 51 tracheostomized patients aged between 19 and 87 years, with tracheal stent for a mean of 46 ± 28 days and with clinical criteria for decannulation. They were submitted to tracheostomy tube occlusion tolerance testfor 24 hours, and then to flexible bronchoscopy. We described and classified the diagnosed laryngotracheal changes. We compared the clinical criteria for decannulation indication with the bronchoscopy-diagnosed laryngotracheal injuries that contraindicated decannulation. We identified the factors that could interfere in decannulation and evaluated the importance of bronchoscopy as part of the process. RESULTS: Forty (80.4% patients had laryngotracheal alterations. Of the 40 patients considered clinically fit to decannulation, eight (20% (p = 0.0007 presented with laryngotracheal injuries at bronchoscopy that contraindicated the procedure. The most frequent laryngeal alteration was vocal cords lesion, in 15 (29% individuals, and granuloma, the most prevalent tracheal lesion, in 14 (27.5% patients. CONCLUSION: flexible bronchoscopy showed a large number of laryngotracheal injuries, the most frequent being the vocal cords injury in the larynx and the granuloma in the trachea, which contributed to increase the decannulation procedure safety.

    Foreign body (FB) inhalation in the tracheobronchial tree is an infrequently encountered event in adults. The diagnosis is suspected in the presence of a clinical history of aspiration and the presence of respiratory symptoms. Management involves confirmation by flexible bronchoscopy, which may be both diagnostic as well as therapeutic. However, in certain situations including those with large FB, FB embedded in granulation tissue or FB with very smooth margins, rigid bronchoscopy may be superior to flexible bronchoscopy in the retrieval of the FB. An alternative to rigid bronchoscopy in such situations may be the use of a cryoprobe. Herein, we describe a patient with a large tracheobronchial FB causing a complete collapse of the left lung and hypoxemia. The FB was successfully extracted using a cryoprobe during flexible bronchoscopy, obviating the need for rigid bronchoscopy.

    To evaluate the frequency of complications in bronchoscopy from data compiled between 1/2/2002 to 1/2/2003. Nineteen Italian centres of thoracic endoscopy participated in the study, for a total of 20,986 bronchoscopies (FBS), including 10,658 explorative bronchoscopies (EB) (50.79%), 5,520 bronchial biopsies (BB) (26.30%), 1,660 transbronchial biopsies (TBB) (7.91%), 1,127 broncho-alveolar lavages (BAL) (5.37%), 930 transbronchial needle-aspirates (TBNA) (4.43%), 1.091 therapeutic bronchoscopies (TB), comprising ND-YAG Laser, argon-plasma, electrocautery knife, stent insertion (5.20%). 82.4% of the procedures involved the use of a flexible bronchoscope, 16.3% were carried out using a rigid bronchoscope and 1.3% using the mixed technique. The total number of complications recorded was 227 (1.08% of the cases examined), including 20 (0.09%) during local anesthesia and pre-medication, 195 (0.92%) during the endoscopic procedures and 12 (0.05%) in the two hours following FBS. The total number of deaths was 4 (0.02%), due to cardiac arrest, pulmonary edema, delayed respiratory failure and shock in pre-medication, respectively. 68.28% of the complications were treated medically, 25.99% by means of endoscopy and 5.72% with surgery. The healing percentage was 98.2%. This study has shown that bronchoscopy is a safe method with low incidence of mortality and complications. The preparation, experience and continuous training of the operators of the medical and nursing team seem to play a fundamental role in reducing the incidence of complications at least in certain procedures such as BB and TBB.

    Foreign body aspiration (FBA) could be a serious life-threatening condition in children. Patients usually underwent bronchoscopy with suspicious of FBA alone. In this study, we aimed to determine which patients need to go to bronchoscopy based on pre-operative findings. Retrospective analysis of patients underwent bronchoscopy between 1999 and 2015 was performed. Clinical symptoms, witnessed aspiration event (WAE), physical examination findings (PEFs) and radiological findings (RFs) were analyzed by multivariate analysis to evaluate the indications of bronchoscopy. 431 patients (266M, 165F) underwent bronchoscopy with a median age of 2 years (7 months-16 years). A foreign body was detected in 68% of the patients. Univariate analysis demonstrated that wheeze was the sole distinctive clinical symptom for detection of FBA (pMultivariate analysis was performed with considering the association between them. The rate of positive bronchoscopy was 91.3% in patients with positive WAE, PEFs and RFs together(84/92). In patients with a positive WAE alone who had not got PEFs and RFs, the rate of positive bronchoscopy was 34.2% (25/73). A foreign body was detected in 84% of the patients who had not got a WAE but positive PEFs and RFs together(21/25). Bronchial laceration was occurred in one patient during bronchoscopy. Pneumothorax was not seen in any of the other patients. The rate of mortality was 0.4% in the overall group (2 patients). The indications of bronchoscopy in suspected FBA are usually based on clinical suspicious. The definition of " suspicous" could be a WAE or positive PEFs and RFs. The association of these factors increase the rate of positive bronchoscopies. In the light of our study, the classical indication for suspected FBA is still valid as "suspicious requires bronchoscopy". Copyright © 2017 Elsevier B.V. All rights reserved.

    Awake Flexible Tracheobronchoscopy (FTB) is an alternative to rigid bronchoscopy or sedated flexible bronchoscopy and allows an awake examination of the tracheobronchial tree. We hypothesized that the ability to perform office bronchoscopy as the need arises during a clinic visit would lead to a high rate of previously undiagnosed and clinically relevant findings. This study reports the rate and nature of such findings for this procedure at our institution. Retrospective chart review. The records of 127 adult patients evaluated at the voice and swallowing disorders clinic between June of 2012 and January of 2015 were reviewed. New findings were defined as new pathology visualized during FTB exam that was not previously diagnosed by means of other diagnostic modalities. A total of 233 scope procedures (84 transnasal bronchoscopies and 149 tracheoscopies) were reviewed, 232 of which were completed and one of which was incomplete due to severe subglottic stenosis. New, clinically relevant findings were seen in 57% of transnasal bronchoscopies (48 of 84) and 21% of tracheoscopies (32 of 149). All of these findings provided additional information directing workup or resulted in a change in patient management. Office-based evaluation of the tracheobronchial tree yields a high rate of new findings. In our study, office bronchoscopy had a 57% rate of new findings and was performed without complications. The utility of tracheoscopy was also apparent in its ability to quickly and safely examine the trachea, with a 21% rate of new findings. 4.

    Bronchoscopy is a commonly used minimally invasive procedure for lung-cancer staging. In standard practice, however, physicians differ greatly in their levels of performance. To address this concern, image-guided intervention (IGI) systems have been devised to improve procedure success. Current IGI bronchoscopy systems based on virtual bronchoscopic navigation (VBN), however, require involvement from the attending technician. This lessens physician control and hinders the overall acceptance of such systems. We propose a hands-free VBN system for planning and guiding bronchoscopy. The system introduces two major contributions. First, it incorporates a new procedure-planning method that automatically computes airway navigation plans conforming to the physician's bronchoscopy training and manual dexterity. Second, it incorporates a guidance strategy for bronchoscope navigation that enables user-friendly system control via a foot switch, coupled with a novel position-verification mechanism. Phantom studies verified that the system enables smooth operation under physician control, while also enabling faster navigation than an existing technician-assisted VBN system. In a clinical human study, we noted a 97% bronchoscopy navigation success rate, in line with existing VBN systems, and a mean guidance time per diagnostic site = 52 s. This represents a guidance time often nearly 3 min faster per diagnostic site than guidance times reported for other technician-assisted VBN systems. Finally, an ergonomic study further asserts the system's acceptability to the physician and long-term potential.

    BACKGROUND: There is significant variation between physicians in terms of how they perform therapeutic bronchoscopy, but there are few data on whether these differences impact effectiveness. METHODS: This was a multicenter registry study of patients undergoing therapeutic bronchoscopy for malignant central airway obstruction. The primary outcome was technical success, defined as reopening the airway lumen to > 50% of normal. Secondary outcomes were dyspnea as measured by the Borg score and health-related quality of life (HRQOL) as measured by the SF-6D. RESULTS: Fifteen centers performed 1,115 procedures on 947 patients. Technical success was achieved in 93% of procedures. Center success rates ranged from 90% to 98% (P = .02). Endobronchial obstruction and stent placement were associated with success, whereas American Society of Anesthesiology (ASA) score > 3, renal failure, primary lung cancer, left mainstem disease, and tracheoesophageal fistula were associated with failure. Clinically significant improvements in dyspnea occurred in 90 of 187 patients measured (48%). Greater baseline dyspnea was associated with greater improvements in dyspnea, whereas smoking, having multiple cancers, and lobar obstruction were associated with smaller improvements. Clinically significant improvements in HRQOL occurred in 76 of 183 patients measured (42%). Greater baseline dyspnea was associated with greater improvements in HRQOL, and lobar obstruction was associated with smaller improvements. CONCLUSIONS: Technical success rates were high overall, with the highest success rates associated with stent placement and endobronchial obstruction. Therapeutic bronchoscopy should not be withheld from patients based solely on an assessment of risk, since patients with the most dyspnea and lowest functional status benefitted the most.

    Full Text Available Aspiration of the lower airways due to foreign body is rare in adults. This study aimed to determine the outcome of patients who received flexible bronchoscopy with different modalities for foreign body removal in the lower airways.Between January 2003 and January 2014, 94 patients diagnosed with foreign body in the lower airways underwent flexible bronchoscopy with different modalities, which included forceps, loop, basket, knife, electromagnet, and cryotherapy. The clinical presentation, foreign body location and characteristics, and applications of flexible bronchoscopy were analyzed.Forty (43% patients had acute aspiration, which developed within one week of foreign body entry and 54 (57% had chronic aspiration. The most common foreign bodies were teeth or bone. More patients with chronic aspiration than those with acute aspiration were referred from the out-patient clinic (48% vs. 28%, but more patients with acute aspiration were referred from the emergency room (35% vs. 6% and intensive care unit (18% vs. 2%. Flexible bronchoscopy with different modalities was used to remove the foreign bodies (85/94, 90%. Electromagnet or cryotherapy was used in nine patients to eliminate the surrounding granulation tissue before foreign body removal. In the nine patients with failed flexible bronchoscopy, eight underwent rigid bronchoscopy instead and one had right lower lung lobectomy for lung abscess.Flexible bronchoscopy with multiple modalities is effective for diagnosing and removing foreign bodies in the lower respiratory airways in adults, with a high success rate (90% and no difference between acute and chronic aspirations.

    2008-05-01

    Full Text Available A significant reduction in arterial blood oxygen saturation during fiberoptic bronchoscopy has been proved but it is not yet known whether all patients need supplemental oxygen during this procedure. The aim of study is to examine the relationship between peak expiratory flow rate (PEFR before bronchoscopy and oxygen desaturation during bronchoscopy. Measurement of PEFR (% predicted performed before bronchoscopy and arterial O2 desaturation was assessed with a pulse oximeter during bronchoscopy. Study performed in 66 patients with a median age 53 years, who had been referred to our bronchoscopy unit. None of the patients received supplemental oxygen before the procedure. Thirty nine cases (59% had an episode of O2 desaturation during bronchoscopy. Of them 25 cases (38% had sustained O2 desaturation, requiring oxygen therapy while 14 cases (21% had momentary desaturation (< 20s not requiring O2 therapy. Oxygen therapy was administered in 58% of cases with PEFR % < 60 and in 83% of cases with PEFR % less than 45 (P, 0.008 and 0.001, respectively. We also observed a significant fall in mean O2 saturation during bronchoscopy (88 ± 4 % compared to prebronchoscopy levels (95 ± 2 % (P < 0.0001. It is concluded that PEFR < 60% and especially < 45% is a reliable predictor of hypoxemia and the need to O2 therapy during bronchoscopy.

    2011-08-01

    Full Text Available Abstract Less than 1% of lung neoplasms are represented by benign tumors. Among these, hamartomas are the most common with an incidence between 0.025% and 0.32%. In relation to the localization, hamartomas are divided into intraparenchymal and endobronchial. Clinical manifestation of an endobronchial hamartoma (EH results from tracheobronchial obstruction or bleeding. Usually, EH localizes in large diameter bronchus. Endoscopic removal is usually recommended. Bronchotomy or parenchimal resection through thoracotomy should be reserved only for cases where the hamatoma cannot be approached through endoscopy, or when irreversible lung functional impairment occurred after prolonged airflow obstruction. Generally, when endoscopic approach is used, this is through rigid bronchoscopy, laser photocoagulation or mechanical resection. Here we present a giant EH occasionally diagnosed and treated by fiberoptic bronchoscopy electrosurgical snaring.

    The role of flexible fiberoptic bronchoscopy (FFB) in the evaluation of pediatric lung disease has expanded dramatically since the original description of the procedure by Wood and Fink in 1978.FFB can be used to evaluate airway anatomy, obtain secretions for culture and biochemical analysis and obtain airway cells or parenchymal tissues for evaluation. Both the upper and lower airway can be examined during FFB. Visual examination can diagnose a variety of congenital abnormalities ( Table 1 ). During FFB a dynamic evaluation of the airways, including the movement of the glottis, vocal cords and lower airways during the respiratory cycle can be performed. These observations can diagnose airway collapse due to malacia or obstruction due to external compression. Additionally, the diameter of the airway lumen and character of the airway mucosa can easily be evaluated. FFB can also identify airway obstruction by secretions and mucus plugs, blood, foreign bodies or masses. Bronchoalveolar lavage (BAL) allows collection of airway and alveolar secretions for evaluation of cellular and immunologic components, evidence of infection and cytology. Therapeutic lavage can be used to treat atelectasis by removing secretions obstructing airways. This approach can be helpful in children with inspissated secretions obstructing both large and small airways ( Figure 1 ). Therapeutic lavage has also been used in the treatment of alveolar proteinosis. Bronchial brushing can add information to bronchoscopic examination by obtaining airway epithelial cells for cytology, to identify intracellular pathogens and to evaluate cilia. Studies have demonstrated the utility of bronchial brushings for the isolation, characterization and culture of primary epithelial cells from children with asthma. Endobronchial biopsies are used for histopathological and immunocytochemical analysis and microbiological culture. Biopsies are often performed to assess cilia function and architecture. In addition

    In flexible endoscopy techniques, such as bronchoscopy, there is often a challenge visualizing the path from start to target based on preoperative data and accessing these during the procedure. An example of this is visualizing only the inside of central airways in bronchoscopy. Virtual bronchoscopy (VB) does not meet the pulmonologist's need to detect, define and sample the frequent targets outside the bronchial wall. Our aim was to develop and study a new visualization technique for navigated bronchoscopy. We extracted the shortest possible path from the top of the trachea to the target along the airway centerline and a corresponding auxiliary route in the opposite lung. A surface structure between the centerlines was developed and displayed. The new technique was tested on non-selective CT data from eight patients using artificial lung targets. The new display technique anchored to centerline curved surface (ACCuSurf) made it easy to detect and interpret anatomical features, targets and neighboring anatomy outside the airways, in all eight patients. ACCuSurf can simplify planning and performing navigated bronchoscopy, meets the challenge of improving orientation and register the direction of the moving endoscope, thus creating an optimal visualization for navigated bronchoscopy.

    The diagnosis and early bronchoscopic extraction of a foreign body (Fb) in children are life-saving measures. Many studies have described the manifestation of foreign body aspiration (FbA); however, only a few analyzed the role of flexible bronchoscopy in the diagnosis of FbA. The aim of this work is to define the indications of flexible bronchoscopy in the management algorithm of suspected FbA. This study was conducted at a tertiary referral University Medical Center with an outpatient clinic and a 20-bed pediatric emergency unit. Between January 2002 and July 2006 children referred with suspected FbA were included in this prospective study. Children with asphyxiating FbA requiring immediate rigid bronchoscopy, were excluded. If there was no convincing evidence of FbA, a diagnostic flexible bronchoscopy was performed under local anesthesia. In the case where a Fb was actually found, extraction was always performed by rigid bronchoscopy. Seventy cases (median age: 2 years, males: 44/females: 26) were analyzed. Among the 19 children who underwent flexible bronchoscopy first, 7 (37%) had a Fb. Among the 51 who underwent rigid bronchoscopy first, 43 had a Fb and 8 (16%) had a negative first rigid bronchoscopy. Predictive signs of a bronchial Fb were a radiopaque Fb, foreign body aspiration syndrome (FbAS) associated with unilaterally decreased breath sounds or localized wheezing and obstructive emphysema or atelectasis. In case of suspected FbA in children, the following management algorithm is suggested: rigid bronchoscopy should be performed solely in case of asphyxia, finding of a radiopaque Fb, or in the presence FbAS associated with unilaterally decreased breath sounds, localized wheezing and obstructive radiological emphysema, or atelectasis. In all other cases, flexible bronchoscopy should be performed first for diagnostic purposes.

    Bronchoscopy is a major step in lung cancer staging. To perform bronchoscopy, the physician uses a procedure plan, derived from a patient's 3D computed-tomography (CT) chest scan, to navigate the bronchoscope through the lung airways. Unfortunately, physicians vary greatly in their ability to perform bronchoscopy. As a result, image-guided bronchoscopy systems, drawing upon the concept of CT-based virtual bronchoscopy (VB), have been proposed. These systems attempt to register the bronchoscope's live position within the chest to a CT-based virtual chest space. Recent methods, which register the bronchoscopic video to CT-based endoluminal airway renderings, show promise but do not enable continuous real-time guidance. We present a CT-video registration method inspired by computer-vision innovations in the fields of image alignment and image-based rendering. In particular, motivated by the Lucas-Kanade algorithm, we propose an inverse-compositional framework built around a gradient-based optimization procedure. We next propose an implementation of the framework suitable for image-guided bronchoscopy. Laboratory tests, involving both single frames and continuous video sequences, demonstrate the robustness and accuracy of the method. Benchmark timing tests indicate that the method can run continuously at 300 frames/s, well beyond the real-time bronchoscopic video rate of 30 frames/s. This compares extremely favorably to the ≥ 1 s/frame speeds of other methods and indicates the method's potential for real-time continuous registration. A human phantom study confirms the method's efficacy for real-time guidance in a controlled setting, and, hence, points the way toward the first interactive CT-video registration approach for image-guided bronchoscopy. Along this line, we demonstrate the method's efficacy in a complete guidance system by presenting a clinical study involving lung cancer patients.

    Bone is a preferred site of metastasis for many solid tumors, and the complications associated with bone metastases can result in significant skeletal morbidity including severe bone pain, pathologic fracture, spinal cord compression, and hypercalcemia of malignancy (HCM). Bisphosphonates are the current standard of care for preventing skeletal complications associated with bone metastases. Clinical trials investigating the benefit of bisphosphonate therapy have used a composite end point defined as a skeletal-related event (SRE) or bone event, which typically includes pathologic fracture, spinal cord compression, radiation or surgery to bone, and HCM. Bisphosphonates have been shown to significantly reduce the incidence of these events in patients with bone metastases. Zoledronic acid (Zometa; Novartis Pharmaceuticals Corp.; East Hanover, NJ), pamidronate (Aredia; Novartis Pharmaceuticals Corp.), clodronate (Bonefos; Anthra Pharmaceuticals; Princeton, NJ), and ibandronate (Bondronat; Hoffmann-La Roche Inc.; Nutley, NJ) all have demonstrated efficacy superior to that of placebo in patients with breast cancer. Zoledronic acid is the only bisphosphonate that has been compared directly with pamidronate, and it was shown by multiple event analysis to be significantly more effective at reducing the risk of an SRE. In patients with prostate cancer, clodronate, etidronate (Didronel; Procter and Gamble Pharmaceuticals, Inc.; Cincinnati, OH), and pamidronate have demonstrated transient palliation of bone pain. However, zoledronic acid is the only bisphosphonate to demonstrate both significant and sustained pain reduction and a significantly lower incidence and longer time to onset of SREs compared with placebo. Zoledronic acid is also the only bisphosphonate to demonstrate efficacy in patients with bone metastases from a variety of other solid tumors, including lung cancer and renal cell carcinoma. In conclusion, bisphosphonates effectively reduce skeletal complications in

    The techniques, drugs and depth of sedation for flexible fiberoptic bronchoscopy is controversial, and several reports consider that the routine use of sedation is not a prerequisite. We evaluate whether the addition of sedation with propofol improves patient tolerance, compared to local anesthesic of the airway only. Eighteen patients with pneumonia undergoing flexible fiberoptic bronchoscopy were included in a randomized, single blind, prospective controlled study. The non-sedation group received airway topical anesthesia, whereas the sedation group received topical anesthesia and intravenous sedation with propofol. The degree of pain, cough, sensation of asphyxiation, degree of amnesia, global tolerance and acceptance of another bronchoscopy in the future were noted. Changes in blood pressure, heart rate and saturation of oxygen by pulse oximetry were also evaluated. The patients in sedation group had less cough (P < 0.05), pain (P < 0.01) and sensation of asphyxiation (P < 0.001). Global tolerance to the procedure was significantly better in the group under sedation (P < 0.01). These patients had total amnesia to the procedure (P < 0.0001), thus is more probable that will accept another bronchoscopy in the future (P < 0.01). There was a significant rise in heart rate and blood pressure in the patients without sedation. There were no differences in oxygen saturation (P = 0.75). Our results show that if we administer propofol for sedation, in addition to local anesthesia of the airway, the tolerance to the procedure is much better. Also it appears that sedation with propofol is safe if we carefully select and monitor the patient.

    Hypoxia and hypercarbia complicate flexible bronchoscopy (FB). Unlike oxygenation by pulse-oximetry, alveolar ventilation is not routinely monitored during FB. The aim of this study was to investigate ventilation in children undergoing FB by measuring carbon-dioxide (CO2 ) levels using the transcutaneous technique. Children admitted for FB were recruited. In addition to routine monitoring, transcutaneous CO2 (TcCO2 ) levels were recorded. All were sedated using the same protocol. Ninety-five children were studied. There was no association between peak TcCO2 or rise in TcCO2 and age, weight percentile, bronchoscope size, or diagnosis. Median baseline TcCO2 was 36 mmHg (IQR 32,40), median peak TcCO2 was 51 mmHg (IQR 43,62) with median TcCO2 rise of 17 mmHg (IQR 6.5,23.7). A rise of 15 mmHg or higher was recorded in 55% (n = 52) patients. Children requiring total propofol dose over 3.5 mg/kg had a significantly higher TcCO2 peak of 57.6 mmHg (IQR 47.8,66.7) compared to 47.1 mmHg (IQR 40,57) (P = 0.004) and a higher rise in TcCO2 22.5 mmHg (IQR 17,33.9) compared to 13.6 mmHg (6,22) (P = 0.001). Results were not affected by intranasal midazolam and broncho-alveolar lavage. No complications were reported. Non clinically significant (i.e., not lower than 90%) brief drops in oxygen saturation were observed. A large proportion of children undergoing FB have significant alveolar hypoventilation indicated by a rise in TcCO2 . Monitoring ventilation with TcCO2 is feasible and should be added during FB particularly in cases that are expected to require large amounts of sedation and patients susceptible to complications from respiratory acidosis.

    Full Text Available In diagnosing the aspiration of the foreign body (AFB in children most important are: medical history, clinical signs and positive radiography of the lungs. Common dilemmas in the diff erential diagnosis are life-threatening asthma attacks or difficult pneumonia. Conventional rigid bronchoscopy (RB is not recommended as a routine method. Virtual bronchoscopy (VB can be a diagnostic tool for solving dilemmas. Fiber-optic bronchoscopy (FOB has a therapeutic stake in severe cases. Herein, we describe a girl, at the age of 6, who was hospitalized due to rapid bronchoconstriction and based on the anamnesis, clinical symptoms and physical fi ndings the suspicion was that she aspirated the foreign body. Due to the poor general condition and possible sequel, the idea of RB was dropped out. Multidetector computed tomography of the chest and VB was performed and AFB was not found. Due to positive epidemiological situation, virus H1N1 was excluded. FOB established that the foreign body does not exist in the airways. During bronchoscopy numerous castings are aspirated from the peripheral airways which lead to faster final recovery. With additional procedures, the diagnosis of asthma was confirmed and for girl that was the first attack. Along with inhaled corticosteroids as prevention she feels well.

    Full Text Available Background. Conventional flexible bronchoscopy has limited sensitivity in the diagnosis of peripheral lung lesions and is dependent on lesion size. However, advancement of CT imaging offers multiplanar reconstruction facilitating enhanced preprocedure planning. This study aims to report efficacy and safety while considering the impact of patient selection and multiplanar CT planning. Method. Prospective case series of patients with peripheral lung lesions suspected of having lung cancer who underwent flexible bronchoscopy (forceps biopsy and lavage. Endobronchial lesions were excluded. Patients with negative results underwent CT-guided transthoracic needle aspiration, surgical biopsy, or clinical-radiological surveillance to establish the final diagnosis. Results. 226 patients were analysed. The diagnostic yield of bronchoscopy was 80.1% (181/226 with a sensitivity of 84.2% and specificity of 100%. In patients with a positive CT-Bronchus sign, the diagnostic yield was 82.4% compared to 72.8% with negative CT-Bronchus sign (p=0.116. Diagnostic yield was 84.9% in lesions > 20 mm and 63.0% in lesions ≤ 20 mm (p=0.001. Six (2.7% patients had transient hypoxia and 2 (0.9% had pneumothorax. There were no serious adverse events. Conclusion. Flexible bronchoscopy with appropriate patient selection and preprocedure planning is more efficacious in obtaining a diagnosis in peripheral lung lesions compared to historical data. This trial is registered with ClinicalTrials.gov Identifier: NCT01374542.

    Full Text Available Since the introduction of the flexible fibreoptic bronchoscope in the late 1960s there have been relatively few technological advances for three decades, aside from the development of a white light video bronchoscope with a miniature charge-coupled device built in its tip replacing the fibreoptics. White light flexible videobronchoscopy with its ancillary devices (forceps biopsy, bronchial brushing, bronchoalveolar lavage, bronchial washings and transbronchial needle aspiration has long been the only established diagnostic bronchoscopic technique. With the advances in microtechnology over the past two decades, recent technical developments such as autofluorescence bronchoscopy and endoscopic ultrasound allow better evaluation of endobronchial, mediastinal and parenchymal lesions.

    Conclusion: Routine flexible bronchoscopy technique has a reasonably high diagnostic yield in current clinical practice. Our study concludes that the diagnostic yield of FOB at our rural setting is comparable with the studies from other centres within the country and abroad. The procedure is more useful in diagnosis when combined with a sound clinical judgment and other supportive investigations. [Natl J Med Res 2013; 3(4.000: 392-395

    The changes of autonomic nervous activity during bronchoscopic procedures are closely related to the development of cardiovascular complications. We aimed to evaluate the changes of autonomic nervous activity during bronchoscopic procedures using R-R interval variability from electrocardiograms (ECGs) obtained during diagnostic bronchoscopy. Twenty-four patients who underwent bronchoscopy were included. Continuous ECG was recorded prior to, during and after the bronchoscopic procedure. Time and frequency domain analyses of heart rate variability were performed. Heart rate increased significantly after pre-medication compared with that before pre-medication and increased further during bronchoscopy. The coefficient of variation (CVRR ) values after pre-medication and during bronchoscopy were significantly higher than those before pre-medication (P = 0.031 and P = 0.041, respectively). The low frequency (LF) power decreased during bronchoscopy. LF powers obtained after bronchoscopy were significantly lower than those obtained before bronchoscopy (P Holter ECG monitoring during diagnostic bronchoscopy was associated with activation of cardiac sympathetic and withdrawal of cardiac parasympathetic regulation, which may contribute to the occurrence of cardiac events during bronchoscopic procedures. So, Holter ECG monitoring during bronchoscopic procedures may confer reduction in cardiovascular events. © 2014 John Wiley & Sons Ltd.

    Lidocaine toxicity usually appears rapidly and is directly correlated with plasma concentrations of the drug. We report a case of a late neurologic toxicity occurring after instillation of lidocaine during fibre-optic bronchoscopy. A patient with bronchiolitis obliterans underwent a diagnostic bronchoscopy. She received multiples instillations of Xylocaine(®) 2% (lidocaine). Three and a half hours later, she had a tonic-clonic seizure. Seven hours later, this recurred. Lidocaine plasma levels were in the toxic range at the time of the first seizure (18.32μg/mL) with a significant decrease in the concentration noted 24hours later. The slow absorption of lidocaine into the blood from the bronchial tree explains the delayed neurologic toxicity. Our observation is a reminder that complications can occur due to high doses of lidocaïne administrated by instillation. Thus, if the recommended dose of lidocaine is exceeded, it is essential to monitor patients closely for a prolonged period, especially those with fibrosing lung disease in order to avoid possible late toxicity.

    To investigate and compare the diagnostic values of bronchoscopy and multi-slice spiral computed tomography (CT) for congenital dysplasia of the respiratory system in infants. Analysis was performed on the clinical data, bronchoscopic findings and multi-slice spiral CT findings of 319 infants (≤1 years old) who underwent bronchoscopy and/or multi-slice spiral CT and were diagnosed with congenital dysplasia of the respiratory system. A total of 476 cases of congenital dysplasia of the respiratory system were found in the 319 infants, including primary dysplasia of the respiratory system (392 cases) and compressive dysplasia of the respiratory system (84 cases). Of the 392 cases of primary dysplasia of the respiratory system, 225 (57.4%) were diagnosed by bronchoscopy versus 167 (42.6%) by multi-slice spiral CT. There were significant differences in etiological diagnosis between bronchoscopy and multi-slice spiral CT in infants with congenital dysplasia of the respiratory system (Pdysplasia of the respiratory system caused by tracheobronchomalacia were diagnosed by bronchoscopy and all 17 cases of primary dysplasia of the respiratory system caused by lung tissue dysplasia were diagnosed by multi-slice spiral CT. Of the 84 cases of compressive dysplasia of the respiratory system, 74 cases were diagnosed by multi-slice spiral CT and only 10 cases were diagnosed by bronchoscopy. Compared with multi-slice spiral CT, bronchoscopy can detect primary dysplasia of the respiratory system more directly. Bronchoscopy is valuable in the confirmed diagnosis of tracheobronchomalacia. Multi-slice spiral CT has a higher diagnostic value for lung tissue dysplasia than bronchoscopy.

    Australian states have embraced clinical networking as a mechanism for managing, organising and improving the quality of care. Using these individualised state approaches to clinical networks, in this paper the authors aim to examine this Australasian "experimentation" and present lessons for other health systems. The paper draws on current knowledge from the literature on clinical networks. The 2010 Inaugural Australasian Clinical Networks Conference also serves as a primary resource, as well as the authors' extensive discussions with policy-makers, managers and clinicians in Australasian systems. Key themes from the literature include: network type (mandated or natural, and hybrids); network purpose; the importance of network objectives; drivers of network success and barriers; the need for consumer engagement; and the difficulty of evaluating network effectiveness. Policy challenges include the establishment of networks for some specialty areas and not others; how to develop common standards across networks; and the need for performance metrics to assess network impact on patient outcomes. Australian networks report difficulties with achieving greater involvement of rural clinicians and indigenous populations, and with private sector clinical engagement. There are challenges too with implementation, at service level, of models of care and recommendations. Clinical networks are becoming a fundamental vehicle for clinical improvement and change across complex organisational and professional boundaries. How to nurture and sustain effective clinical networks is of import to every health system and the authors invite stakeholders in health systems to network and share their empirical research on clinical networks to assist with distinguishing the evidence from the rhetoric.

    The study illustrates advantages of Fiberoptic Bronchoscopy, a new service started at St. Luke’s General Hospital in patient care since April 2014. Retrospective review of Bronchoscopies and referrals to Tertiary care unit for Bronchoscopy, prior and after initiation of service at St. Luke’s Hospital were studied. In total, 106 procedures were performed out of which 103(98%) were for diagnostic purpose. Common indications for bronchoscopy were functional airway assessment in 38 cases (35%) of chronic cough, 26 cases (24.8%) of suspected malignancy. The average time taken for procedure was 15 + 1 minute with overall rate of complication recorded in 1 case (0.95%). 32(30%) inpatients were referred before bronchoscopy services were started locally. Fifteen (14%) patients were referred for Endobronchial Ultrasound (EBUS) after diagnostic procedure performed at St. Luke’s Hospital. To conclude, Bronchoscopy is a safe procedure used for diagnosis of various Lung conditions. The services offered locally reduced the time and cost involved in referrals. The diagnostic bronchoscopies performed for malignancy at St. Luke’s Hospital have rightly increased references for EBUS at Tertiary care Unit

    Past work has shown that guidance systems help improve both the navigation through airways and final biopsy of regions of interest via bronchoscopy. We have previously proposed an image-based bronchoscopic guidance system. The system, however, has three issues that arise during navigation: 1) sudden disorienting changes can occur in endoluminal views; 2) more feedback could be afforded during navigation; and 3) the system's graphical user interface (GUI) lacks a convenient interface for smooth navigation between bifurcations. In order to alleviate these issues, we present an improved navigation system. The improvements offer the following: 1) an enhanced visual presentation; 2) smooth navigation; 3) an interface for handling registration errors; and 4) improved bifurcation-point identification. The improved navigation system thus provides significant ergonomic and navigational advantages over the previous system.

    Full Text Available Chiara Rosina, Ferdinando Bottoni, Giovanni StaurenghiLuigi Sacco Hospital, University of Milano, ItalyAbstract: Pegaptanib sodium (Macugen® blocks the extracellular vascular endothelial growth factor (VEGF isoform VEGF165, whose elevated levels are associated with the development of choroidal neovascularization (CNV. This selective inhibition prevents binding to the VEGF receptors and the development of the increased vascular permeability and the CNV associated with neovascular age-related degeneration (AMD. The VEGF Inhibition Study In Ocular Neovascularization (VISION demonstrated that pegaptanib sodium confers clinically meaningful benefit in the treatment of all angiographic subtypes of neovascular AMD. It also has a favorable safety profile after 1 and 2 years of continuous treatment, and recent data suggest that the agent has a disease-modifying effect. Post hoc analysis of VISION suggests that treatment benefit may be greatest in patients with early lesions, in whom 80% achieved the primary endpoint of <15 letters lost, 47% maintained visual acuity (VA, and 20% gained ≥15 letters of vision. Similarly, our own clinical experience indicates that pegaptanib sodium achieves better outcomes in early lesions than in established lesions, particularly in patients with previously untreated minimally classic and occult lesions in whom VA improvement and lesion size stabilization has been recorded. Observations indicate that pegaptanib sodium has a slower mode of action than unselective VEGF inhibitors, resulting in an average of 3–4 injections being required to stabilize VA and lesion size. Pegaptanib sodium has good efficacy and safety profiles and represents a good treatment option for patients with early CNV membranes associated with neovascular AMD.Keywords: vascular endothelial growth factor (VEGF, choroidal neovasularization (CNV, age-related macular degeneration (AMD, pegaptanib sodium, early lesions, visual acuity (VA

    Recently, ultra-thin bronchoscopy has made it possible to observe smaller bronchi not visualized using standard techniques. We describe a case of pulmonary mucormycosis with cavitation, diagnosed using an ultra-thin bronchoscope. A 15-year-old girl with acute myeloid leukaemia had taken oral prednisolone, 60 mg/day, for graft versus host disease after haematopoietic stem cell transplantation. She was admitted to our hospital with fever and a large cavitary lesion in the right hilum. Using an ultra-thin bronchoscope, the interior of the cavity in the superior segment of the right lower lobe was observed. The bronchoscopic findings revealed debris adhering to the cavity wall with a small volume of effusion. Cunninghamella bertholletiae was isolated from the effusion specimen obtained using the bronchoscope. Pulmonary mucormycosis (C. bertholletiae) complicating an immunocompromised state was diagnosed. Ultra-thin bronchoscopy is useful to diagnose complex pulmonary infections and more research is needed to verify its clinical indications and utility.

    Background Flexible bronchoscopy is increasingly used for diagnostic and therapeutic purposes. We aimed to examine the safety of flexible bronchoscopy with moderate sedation in patients with COPD. Methods This study is a prospective, longitudinal, case–control, single-center study including 1,400 consecutive patients. After clinical and lung function assessments, patients were dichotomized in COPD or non-COPD groups. The primary end point was the combined incidence of complications. Results The incidence of complications was similar in patients with and without COPD and independent of forced expiratory volume in the first second % predicted. Patients with COPD more frequently required insertion of a naso- or oropharyngeal airway; however, this difference was no longer significant after adjustment for age, gender, and duration of the procedure. Hypotension was significantly more common among patients with COPD. The number of episodes of hypoxemia ≤90% did not differ between the groups. However, patients with COPD had a lower mean and nadir transcutaneous oxygen saturation. Transcutaneous carbon dioxide tension (PtcCO2) change over the time course was similar in both groups, but both peak PtcCO2 and time on PtcCO2 >45 mmHg were higher in the COPD group. There were no differences in patient-reported outcomes. Conclusion The safety of flexible bronchoscopy is similar in patients with and without COPD. This finding confirms the suitability of the procedure for both clinical and research indications. PMID:28115841

    2012-01-01

    Reading diagnostic medical images usually requires the expertise of a specialist physician. To aid physicians we have developed an algorithm that deduces medical information by analysing colour nuances of an image obtained by bronchoscopy. The goal is to ensure a high probability of detecting bronchial cancer. Autofluorescent bronchoscopy images are analysed by the proposed algorithm. The machine-made diagnoses of early cancer stages are highly correlated with the diagnoses made by a medical ...

    An anaesthetic technique for bronchoscopy is described, based on increments of methohexitone given in strict relation to body weight and time, suxamethonium being used to produce relaxation. There was no awareness in the 75 patients studied, while the recovery was rapid and unrelated to the duration of bronchoscopy. The efficacy of small aliquots of lignocaine in reducing injection pain was the same whether given before, or mixed with, the initial methohexitone injection. Other sequelae relating to the anaesthetic technique were minimal. PMID:7241441

    The usual haemodynamic response to fibreoptic bronchoscopy is an increase in heart rate and blood pressure. We therefore compared, in a prospective, randomised, double-blind study, the effect of two doses of oral clonidine premedication (150 microg or 300 microg) with placebo (control group) on the haemodynamic alterations in 62 patients who underwent elective fibreoptic bronchoscopy. Significant increases in blood pressure and heart rate were observed during fibreoptic bronchoscopy only in the control group. Clonidine 150 microg blunted the haemodynamic response to fibreoptic bronchoscopy (p premedicated with 300 microg clonidine. Throughout the study nine patients (75%) in the 300 microg clonidine group were treated at least once for hypotension. Compared with the control group, time to awakening was significantly longer only in patients premedicated with 300 microg clonidine. In conclusion, premedication with 150 microg oral clonidine attenuates haemodynamic responses to fibreoptic bronchoscopy, without causing excessive haemodynamic depression and sedation. These data encourage the administration of clonidine as premedication in patients undergoing fibreoptic bronchoscopy, particularly in those with, or at risk for, coronary artery disease.

    In children undergoing bronchoscopy for evaluation of stridor or respiratory symptoms, movement of the vocal cords is routinely assessed at the conclusion of flexible bronchoscopy with children still anesthetized. The effect of anesthesia on vocal cord function is not well described. This study aimed to characterize the relationship between depth of propofol anesthesia, as measured by Bispectral Index (BIS), and vocal cord movement in pediatric patients. Children between 6 months and 12 years of age presenting for diagnostic flexible bronchoscopy were enrolled in this prospective observational study. Anesthesia was maintained with a propofol infusion which was discontinued upon completion of the lower airway evaluation. An independent observer recorded the BIS score every 15 sec from discontinuation of propofol whereas the pulmonologist continued to observe vocal cord motion. BIS scores were also recorded for each observed clinical endpoint (paradoxical and normal vocal cord movement, complete vocal cord closure, and volitional movement). Data were analyzed for 47 subjects. The BIS values increased significantly from the conclusion of the lower airway evaluation with return of normal vocal cord movement, complete vocal cord closure, and volitional movement (P propofol anesthesia is related to decreasing anesthetic depth with complete vocal cord closure occurring at BIS values near those associated with volitional movement.

    To evaluate the feasibility of and the potential for using optical coherence tomography in conjunction with conventional bronchoscopy in the evaluation of the airways. Methods: This was a pilot study based on an ex vivo experimental model involving three animals: one adult New Zealand rabbit and two Landrace pigs. An optical coherence tomography imaging catheter was inserted through the working channel of a flexible bronchoscope in order to reach the distal trachea of the animals. Images of the walls of the trachea were systematically taken along its entire length, from the distal to the proximal portion. Results: The imaging catheter was easily adapted to the working channel of the bronchoscope. High-resolution images of cross sections of the trachea were taken in real time, precisely delineating microstructures, such as the epithelium, submucosa, and cartilage, as well as the adventitia of the anterior and lateral tracheal walls. The corresponding layers of the epithelium, mucosa, and cartilage were clearly differentiated. The mucosa, submucosa, and trachealis muscle were clearly identified in the posterior wall. Conclusions: It is feasible to use an optical coherence tomography imaging catheter in combination with a flexible bronchoscope. Optical coherence tomography produces high resolution images that reveal the microanatomy of the trachea, including structures that are typically seen only on images produced by conventional histology.

    Midazolam is widely used as a sedative agent to produce amnesia in patients undergoing fibre-optic bronchoscopy. However, if a patient does not receive sufficient local anaesthesia, continuous severe cough and physical movement may interrupt the procedure and reduce its safety. We therefore examined whether codeine phosphate is a useful premedication for bronchoscopy. The study design was a randomized comparison between codeine phosphate and a placebo in patients undergoing light local anaesthesia and midazolam sedation. We used low dose local anaesthesia (5 ml of nebulized 2% xylocaine) on the assumption of insufficient local anaesthesia. Patients were allocated to receive codeine phosphate 0.4 mg kg-1 or a saline placebo 60 min before they were sedated with i.v. midazolam. If the patients exhibited severe cough during bronchoscopy, intrabronchial supplemental local anaesthesia (2% xylocaine solution in 1 ml increments) was instilled via a bronchoscope to the trachea and segmental bronchi to suppress the cough. The dose of supplemental xylocaine was assessed and the requirements were significantly lower in the codeine group compared to the placebo group: 36.4 +/- 10.2 mg vs. 95.1 +/- 24.6 mg, respectively. After bronchoscopy, patients were interviewed by a doctor to assess their willingness to undergo a repeat procedure if one was clinically indicated, but no significant difference was observed between the two groups. If local anaesthesia is insufficient, midazolam together with codeine phosphate premedication is useful for both the patient and the bronchoscopist.

    Patients undergoing flexible bronchoscopy usually experience anxiety before and during the procedure. We performed this study to investigate whether verbal empathy and intentional touch from a bronchoscopist could reduce anxiety in patients undergoing flexible bronchoscopy. We conducted a prospective randomized trial in a university-affiliated hospital. Participants were randomly assigned to one of the following groups: a control group, a verbal empathy group, or a verbal empathy and touch group. The staff pulmonologist performing bronchoscopy expressed verbal empathy and used touch by speaking to the patient (using predefined short statements) and making eye contact, and by laying his/her left hand on the patient's right shoulder. We assessed the level of patient anxiety with a visual analog scale before and after the intervention. Participants were 267 patients with a median age of 65 years; 62.2% were men. Although there were no differences in changes in anxiety between the three groups, subgroup analysis of the visual analog scale including participants with higher baseline anxiety (empathy and touch group participants with anxiety ≥60 mm; empathy group and empathy and touch group participants with anxiety ≥70 mm) showed a larger reduction in anxiety than the control group. Verbal empathy and touch given by a bronchoscopist before bronchoscopy reduced anxiety in patients with high baseline anxiety levels. © 2016 S. Karger AG, Basel.

    From October 1991 through April 1992, 16 infants aged 5 to 25 months (mean age 14.3 months) underwent bronchoscopy with a flexible fiberoptic bronchoscope, under local anesthesia. The technique is described in detail. Reasons for bronchoscopy included recurrent or persistent pneumonia (n = 4), persistent atelectasia (n = 4), lymphadenopathy and/or airway compression (n = 2), suspected foreign body (n = 2), bronchoalveolar lavage to investigate diffuse interstitial lung disease (n = 2), and severe recurrent wheezing (n = 2). The procedure established the accurate diagnosis in 14 cases. Adverse events (32%) were minor (transient hypoxia, n = 3; moderate fever, n = 1; and laryngospasm, n = 1) and resolved completely. Flexible fiberoptic bronchoscopy under local anesthesia is a simple procedure which is safe in patients under 30 months of age when performed by a experienced operator in an adequate facility. This method is useful for the diagnosis and/or treatment of a broad spectrum of conditions.

    Full Text Available Bleeding is one of the most feared complications of flexible bronchoscopy. Although infrequent, it can be catastrophic and result in fatal outcomes. Compared to other endoscopic procedures, the risk of morbidity and mortality from the bleeding is increased, as even a small amount of blood can fill the tracheobronchial tree and lead to respiratory failure. Patients using antithrombotic agents (ATAs have higher bleeding risk. A thorough understanding of the different ATAs is critical to manage patients during the peri-procedural period. A decision to stop an ATA before bronchoscopy should take into account a variety of factors, including indication for its use and the type of procedure. This article serves as a detailed review on the different ATAs, their pharmacokinetics and the pre- and post-bronchoscopy management of patients receiving these medications.

    During hospital bronchoscopy examinations, aerosols emitted from the patient's during coughing can be found suspended in the ambient air. The aerosols can contain pathogenic microorganisms. Depending on their size, these microorganisms can remain in the air for a long time. The objective of this study was to measure the sizes and concentrations of the biological and non-biological particles produced during bronchoscopy examinations, and to propose preventive or corrective measures. Two bronchoscopy rooms were studied. An aerodynamic particle sizer (UV-APS) was used to establish the concentrations of the particles present and their size distributions. This instrument determines the aerodynamic diameter of the aerosols and can distinguish fluorescent (bioaerosols) and non-fluorescent particles. Reference concentrations were measured before the start of the examinations (morning background concentrations). They were used as comparison levels for the concentrations measured during and at the end of the bronchoscopies. In parallel, computational fluid dynamics (CFD) made it possible to isolate and understand different factors that can affect the concentration levels in bronchoscopy rooms. The concentrations of the non-fluorescent and fluorescent particles (bioaerosols) were significantly higher (p ≤ 0.05) during the bronchoscopy examinations than the reference concentrations. For the investigated factors, the bioaerosol concentrations were significantly higher during bronchoscope insertion tasks. The time required at the end of the day for the bioaerosols to reach the morning reference concentrations was about fifteen minutes. The average particle sizes were 2.9 μm for the fluorescent particles (bioaerosols) and 0.9 μm for the non-fluorescent particles. Our models based on computational fluid dynamics (CFD) enabled us to observe the behaviour of aerosols for the different rooms.

    Full Text Available Peter Grendelmeier, Michael Tamm, Kathleen Jahn, Eric Pflimlin, Daiana Stolz Clinic of Pulmonary Medicine and Respiratory Cell Research, University Hospital Basel, Petersgraben, Basel, Switzerland Background: Flexible bronchoscopy is increasingly used for diagnostic and therapeutic purposes. We aimed to examine the safety of flexible bronchoscopy with moderate sedation in patients with COPD. Methods: This study is a prospective, longitudinal, case–control, single-center study including 1,400 consecutive patients. After clinical and lung function assessments, patients were dichotomized in COPD or non-COPD groups. The primary end point was the combined incidence of complications. Results: The incidence of complications was similar in patients with and without COPD and independent of forced expiratory volume in the first second % predicted. Patients with COPD more frequently required insertion of a naso- or oropharyngeal airway; however, this difference was no longer significant after adjustment for age, gender, and duration of the procedure. Hypotension was significantly more common among patients with COPD. The number of episodes of hypoxemia ≤90% did not differ between the groups. However, patients with COPD had a lower mean and nadir transcutaneous oxygen saturation. Transcutaneous carbon dioxide tension (PtcCO2 change over the time course was similar in both groups, but both peak PtcCO2 and time on PtcCO2 >45 mmHg were higher in the COPD group. There were no differences in patient-reported outcomes. Conclusion: The safety of flexible bronchoscopy is similar in patients with and without COPD. This finding confirms the suitability of the procedure for both clinical and research indications. Keywords: bronchoalveolar lavage, propofol, complication, risk, respiratory insufficiency

    To implement a shared learning approach through fourth-year students' mentorship of third-year students and to assess the perceptions of the mentored students on the value of their shared learning experience. We introduced the shared learning experience in clinical pharmacy and pharmacotherapeutic practice experiences involving 87 third-year and 51 fourth-year students. Both student groups undertook the practice experiences together, with third-year students working in smaller groups mentored by fourth-year students. A majority of the students (> 75%) believed that they learned to work as a team during their practice experiences and that the shared learning approach provided an opportunity to practice their communication skills. Similarly, most respondents (> 70%) agreed that the new approach would help them become effective members of the healthcare team and would facilitate their professional relationships in future practice. Almost two-thirds of the students believed that the shared learning enhanced their ability to understand clinical problems. However, about 31% of the pharmacy students felt that they could have learned clinical problem-solving skills equally well working only with peers from their own student group. The pharmacy students in the current study generally believed that the shared-learning approach enhanced their ability to understand clinical problems and improved their communication and teamwork skills. Both groups of students were positive that they had acquired some skills through the shared-learning approach.

    Full Text Available Background and Aim: Due to its easy maneuverability, patient comfort and documented safety as an outpatient procedure, flexible bronchoscopy (FB has replaced rigid bronchoscopy for routine diagnostic use. Herein, we report our 34-year experience with outpatient performance of FB. Materials and Methods: This was a retrospective analysis of all FB procedures performed between September 1979 and November 2013 (period I: 1979-1990; period II: 1991-2000; period III: 2001-2013 in a tertiary care hospital. Demographic profile of patients, indications for performing FB, and annual and seasonal trends were noted from the records. Results: A total of 24,814 bronchoscopies were performed during the study period. The mean (SD age of patients (71.6% males was 48.4 (15.5 years. The number of procedures performed per decade showed an absolute increase by 322%. The most common indication for FB was suspected bronchogenic carcinoma (32.2% followed by pulmonary infections (18.6% and interstitial lung diseases (13%. The proportion of annual cases due to interstitial lung diseases (3.9% in period I to 16.2% in period III increased over the years, whereas disorders such as hemoptysis and pleural effusion showed a declining trend as an indication for FB. A seasonal trend was observed for diseases such as sarcoidosis, bronchogenic carcinoma and pulmonary infections. Six deaths were encountered during the study period in patients undergoing FB. Conclusion: FB is increasingly being performed in the diagnosis of respiratory disorders and is a safe outpatient procedure. Although bronchogenic carcinoma remains a common indication for performing FB, benign conditions such as pulmonary infections and sarcoidosis constitute important indications in the Indian scenario.

    The clinical learning experience is used in nursing programs of study worldwide to prepare nurses for professional practice. This study's purpose was to use Naturalistic Inquiry to understand the experiences of staff nurses in an obstetrical unit with undergraduate nursing students present for clinical learning. A convenience sample of 12 staff nurses, employed on a Family Birth Center, participated in semi-structured interviews. The constant comparative method as modified by Lincoln and Guba was used to analyze data. Five themes related to staff nurses experiences of clinical learning were identified: Giving and Receiving; Advancing Professionally and Personally; Balancing Act; Getting to Know and Working with You; and Past and Present. This research highlights staff nurses' experiences of clinical learning in undergraduate nursing education. Staff nurses exert a powerful, long lasting influence on students. A need exists to prepare and judiciously select nurses to work with students. Clinical agencies and universities can take joint responsibility providing tangible incentives, financial compensation, and recognition to all nurses working with nursing students.

    This paper reflects on the experiences of healthcare students with dyslexia in order to raise awareness of the potential challenges for dyslexic student radiographers and their clinical educators. With widening participation policies it is likely that the number of student radiographers with specific learning difficulties such as dyslexia will continue to increase. A review of the literature associated with dyslexia in healthcare education was performed in order to provide an overview of the current position. Although Higher Education Institutions (HEIs) have embraced the support and learning opportunities for dyslexic students at university, evidence would suggest that this is not reflected in the clinical departments. The current literature strongly suggests that since the risk of errors with clinical information is far more significant within the clinical placement, there is an immediate requirement for greater understanding, robust support and risk assessment systems. This review considers the problems experienced by dyslexic students, coping strategies they employ and the possible implications for clinical radiography education.

    Full Text Available Background and Objective: Appropriate clinical environment has an important role in preparing students to use learned knowledge in practice through providing learning opportunities. Since the students’ experiences in the clinical setting affect on quality of their learning, the current study aimed to explain the experiences of nursing students concerning clinical education setting. Materials and Method: The current study was conducted based on conventional content analysis. Sampling was done purposively and the participants were 13 last year nursing students in Zabol Nursing and Midwifery School in 2013-2014. Data collection was done through in-depth semi-structured interviews. Data analysis was conducted through qualitative content analysis approach. Results: Based on the results, five major categories including threats, vision, dual forces, mindset and students’ action to clinical education and also10 subcategorie were identified. Conclusion: Since the formation of students’ experiences in these environments is one of the predictive factors in achieving their learning and in facilitating the professionalization process, thus the attention of managers in clinical settings is very important for decreasing the threats and concerns for students. In this way, the marred prospects of profession can be recovered through the meeting students’ expectations, attractiveness of the profession can be increased and the positive belief, actions and feelings can be created in students.

    2002-01-01

    To describe a clinical scenario consistent with the diagnosis of cerebral arterial gas embolism (CAGE) acquired during an outpatient bronchoscopy. Our discussion explores the mechanisms and diagnosis of CAGE and the role of hyperbaric oxygen therapy. A diagnostic bronchoscopy was performed on a 70-yr-old man who had had a lobectomy for bronchogenic carcinoma three months earlier. During the direct insufflation of oxygen into the right middle lobe bronchus, the patient became unresponsive and developed subcutaneous emphysema. Immediately, an endotracheal tube and bilateral chest tubes were placed with resultant improvement in his oxygen saturation. However, he remained unresponsive with extensor and flexor responses to pain. Later, in the intensive care unit, he exhibited seizure activity requiring anticonvulsant therapy. Sedation was utilized only briefly to facilitate controlled ventilation. Investigations revealed a negative computerized tomography (CT) scan of the head, a normal cerebral spinal fluid examination, a CT chest that showed evidence of barotrauma, and an abnormal electroencephalogram. Fifty-two hours after the event, he was treated for presumed CAGE with hyperbaric oxygen using a modified United States Navy Table 6. Twelve hours later he had regained consciousness and was extubated. He underwent two more hyperbaric treatments and was discharged from hospital one week after the event, fully recovered. A patient with presumed CAGE made a complete recovery following treatment with hyperbaric oxygen therapy even though it was initiated after a significant time delay.

    Central airway obstructive infections (CAOI) are challenging medical conditions that may represent an advanced and complicated process of ongoing infections. The epidemiology of CAOI is unknown as well as the pathophysiology and the mechanism of development. This is due to sparse data in the literature that consists mainly of case reports and retrospective case series. CAOI can be caused by fungal, bacterial, parasitic and viral infections. Most patients with CAOI can be diagnosed clinically and with chest imaging, which demonstrate obstruction of the central airways. However, bronchoscopy is commonly used to confirm and obtain a specific diagnosis to guide specific therapy. In recent years, interventional pulmonology (IP) is becoming widely available and offer a minimally invasive approach for the management of central airway diseases such as cancers, benign strictures, and other conditions. Various bronchoscopic modalities are used to treat central airway obstruction (CAO), such as mechanical debulking, endobronchial laser therapy, electrocautery, argon plasma coagulation, cryotherapy, and airway stenting. In patients with CAOI, the role of therapeutic bronchoscopy is not clearly defined, but many isolated reports in the literature described bronchoscopic intervention in combination with medical therapy as the initial management approach. In this paper, we present cases of CAOI that underwent bronchoscopic intervention as part of their management. We described the infectious etiology, locations, bronchoscopic findings and bronchoscopic modalities for airway management.

Widened access to university education has meant an increase in the number of students with dyslexia. A limited number of studies have explored the academic experiences of dyslexic student nurses. However, nursing students in the United Kingdom spend 50% of their programme in practice settings, and there are no studies detailing their clinical experiences. This qualitative exploratory study involved tape-recorded interviews with a convenience sample of 18 nursing students with a formal dyslexia diagnosis. Data were collected in 2003-2004 and were analysed using thematic analysis. Participants described a number of personalized approaches to managing their difficulties in practice. Whilst many of these may be useful to non-dyslexic students, descriptions of, for example, avoiding answering the telephone, were inappropriate. Some participants contended with discrimination and ridicule, often choosing not to disclose their disability. Less acute clinical environments appeared to provide more satisfying working experience, and this factor may be influential in shaping future career options. Participants valued more time and an undisturbed place to complete clinical documentation. Heightened self-awareness promoted patient safety as the major concern for study participants. Positive aspects of dyslexia were never raised or acknowledged by participants. The clinical setting provides a challenging environment for nursing students with dyslexia, who find personalized ways to manage their disability. A dyslexia diagnosis continues to carry a stigma that may result in non-disclosure, with implications for the level of support available. Greater awareness of the practice-specific needs of such students is required to ensure appropriate support and public safety.

    BACKGROUND: There are significant variations in how therapeutic bronchoscopy for malignant airway obstruction is performed. Relatively few studies have compared how these approaches affect the incidence of complications. METHODS: We used the American College of Chest Physicians (CHEST) Quality Improvement Registry, Evaluation, and Education (AQuIRE) program registry to conduct a multicenter study of patients undergoing therapeutic bronchoscopy for malignant central airway obstruction. The primary outcome was the incidence of complications. Secondary outcomes were incidence of bleeding, hypoxemia, respiratory failure, adverse events, escalation in level of care, and 30-day mortality. RESULTS: Fifteen centers performed 1,115 procedures on 947 patients. There were significant differences among centers in the type of anesthesia (moderate vs deep or general anesthesia, P 3, redo therapeutic bronchoscopy, and moderate sedation. The 30-day mortality was 14.8%; mortality varied among centers (range, 7.7%-20.2%, P = .02). Risk factors for 30-day mortality included Zubrod score > 1, ASA score > 3, intrinsic or mixed obstruction, and stent placement. CONCLUSIONS: Use of moderate sedation and stents varies significantly among centers. These factors are associated with increased complications and 30-day mortality, respectively. PMID:25741903

    Many technical innovations in multimodal radiologic imaging and bronchoscopy have emerged recently in the effort against lung cancer. Modern X-ray computed-tomography (CT) scanners provide three-dimensional (3D) high-resolution chest images, positron emission tomography (PET) scanners give complementary molecular imaging data, and new integrated PET/CT scanners combine the strengths of both modalities. State-of-the-art bronchoscopes permit minimally invasive tissue sampling, with vivid endobronchial video enabling navigation deep into the airway-tree periphery, while complementary endobronchial ultrasound (EBUS) reveals local views of anatomical structures outside the airways. In addition, image-guided intervention (IGI) systems have proven their utility for CT-based planning and guidance of bronchoscopy. Unfortunately, no IGI system exists that integrates all sources effectively through the complete lung-cancer staging work flow. This paper presents a prototype of a computer-based multimodal IGI system that strives to fill this need. The system combines a wide range of automatic and semi-automatic image-processing tools for multimodal data fusion and procedure planning. It also provides a flexible graphical user interface for follow-on guidance of bronchoscopy/EBUS. Human-study results demonstrate the system's potential.

    Not only is globalization expanding areas of human activity, it is also influencing the variety of educational offerings in universities. Therefore, globalization must be considered by nurse educators as they reevaluate ways of preparing nursing students to meet the health care needs of populations they currently serve and will care for in the future. Study abroad programs have been encouraged to be part of the college experience in the United States for more than 30 years; however, these programs have been relatively lacking in nursing education. Most of the study abroad programs described in the nursing literature are research-based or first-person accounts of an experience and provide little information about planning a study abroad program. This article describes a study abroad learning experience for senior nursing students and discusses the issues such as student selection, student safety, and available clinical experiences that need to be considered before undertaking such an endeavor.

    Rationale: Advanced bronchoscopy techniques such as electromagnetic navigation (EMN) have been studied in clinical trials, but there are no randomized studies comparing EMN with standard bronchoscopy. Objectives: To measure and identify the determinants of diagnostic yield for bronchoscopy in patients with peripheral lung lesions. Secondary outcomes included diagnostic yield of different sampling techniques, complications, and practice pattern variations. Methods: We used the AQuIRE (ACCP Quality Improvement Registry, Evaluation, and Education) registry to conduct a multicenter study of consecutive patients who underwent transbronchial biopsy (TBBx) for evaluation of peripheral lesions. Measurements and Main Results: Fifteen centers with 22 physicians enrolled 581 patients. Of the 581 patients, 312 (53.7%) had a diagnostic bronchoscopy. Unadjusted for other factors, the diagnostic yield was 63.7% when no radial endobronchial ultrasound (r-EBUS) and no EMN were used, 57.0% with r-EBUS alone, 38.5% with EMN alone, and 47.1% with EMN combined with r-EBUS. In multivariate analysis, peripheral transbronchial needle aspiration (TBNA), larger lesion size, nonupper lobe location, and tobacco use were associated with increased diagnostic yield, whereas EMN was associated with lower diagnostic yield. Peripheral TBNA was used in 16.4% of cases. TBNA was diagnostic, whereas TBBx was nondiagnostic in 9.5% of cases in which both were performed. Complications occurred in 13 (2.2%) patients, and pneumothorax occurred in 10 (1.7%) patients. There were significant differences between centers and physicians in terms of case selection, sampling methods, and anesthesia. Medical center diagnostic yields ranged from 33 to 73% (P = 0.16). Conclusions: Peripheral TBNA improved diagnostic yield for peripheral lesions but was underused. The diagnostic yields of EMN and r-EBUS were lower than expected, even after adjustment.

The learning environment afforded to students during clinical tutorials contributes substantially to their knowledge, thinking, and learning. Situated cognition theory posits that the depth and breadth of the students' learning experience is dependent upon the attitude of the clinical teacher, the structure of the tutorial, and the understanding of tutorial and learning objectives. This theory provides a useful framework to conceptualize how students' experience within their clinical tutorials impacts their knowledge, thinking, and learning. Methods: The study was conducted with one cohort (n=301 of students who had completed year 1 of the medical program at Sydney Medical School in 2013. All students were asked to complete a three-part questionnaire regarding their perceptions of their clinical tutor's attributes, the consistency of the tutor, and the best features of the tutorials and need for improvement. Both quantitative and qualitative data were collected and analyzed using descriptive statistics. Results: The response rate to the questionnaire was 88% (265/301. Students perceived that their tutors displayed good communication skills and enthusiasm, encouraged their learning, and were empathetic toward patients. Fifty-two percent of students reported having the same communications tutor for the entire year, and 28% reported having the same physical examination tutor for the entire year. Students would like increased patient contact, greater structure within their tutorials, and greater alignment of teaching with the curriculum. Conclusion: Situated cognition theory provides a valuable lens to view students' experience of learning within the

    Deciding what risks to disclose before a procedure is often challenging for clinicians. Consecutive patients undergoing elective fibreoptic bronchoscopy were randomised to receive simple or more detailed written information about the risks of the procedure and the effects on anxiety and satisfaction levels were compared. A 100 mm anxiety visual analogue scale (VAS) and a modified Amsterdam preoperative anxiety (scored 4-20) scale (APAIS) were completed before and after reading the designated information leaflet. Following bronchoscopy, subjects completed a satisfaction questionnaire. Of 142 consecutive patients, 122 (86%) (mean age 57.8 years, 53% male) completed the study. Baseline demographic, clinical and anxiety measures were similar in the two groups. Those who received more detailed risk information had significantly greater increase in anxiety levels than those who received simple information on both the VAS (mean 14.0 (95% CI 10.1 to 17.9) vs 2.5 (95% CI -1.4 to 6.4), pinformation reported that they felt they had received too much information about complications or that the information they had received about bronchoscopy had been worrying. Provision of more detailed risk information before bronchoscopy may come at the cost of a small but significant increase in anxiety.

    Full Text Available Background: Bronchoscopic procedures are associated with costs for purchasing and maintaining the equipment. Significant share of bronchoscopy unit budget represent costs of repairs for damaged bronchoscopes which are supposedly higher in the teaching centers. The purpose of the study was to determine frequency, sort and cause of bronchoscope damages as well as costs of repair.Methods: We retrospectively studied frequency, sort, cause and repair costs of bronchoscope damages for 13 new bronchoscopes, which were introduced in a program between August 1, 2001 and December 31, 2006.Results: We registered 47 bronchoscope damages during the study, which represents 1 damage per 141.6 procedures. 6 (12.7 % damages were potentially preventable with more careful approach. The most frequent wear and tear injury was rubber sheath injury on the distal bending portion of flexible bronchoscope and the most frequent preventable injury was the damage of the working channel of the bronchoscope. Repair costs amounted to 34,950.00 EUR, which means 5.25 EUR per procedure. We could spare mostly 17,781.00 EUR with more attentive work. Application of the bronchoscopes for educational purposes was not associated with higher rate of bronchoscope damages at our institution.Conclusions: Repair costs represent a significant share of bronchoscopy unit budget. We demonstrated that only a smaller number of bronchoscope damages in our unit are potentially preventable, but they still represent an important amount of expenses. Relatively small share of preventable damages during regular program and teaching procedures is attributable to a good bronchoscopy training programme, which is attended future bronchoscopists in our institution.

    Broncholithiasis is the presence of calcific material within the tracheobronchial tree. Asymptomatic patients can be managed with observation only, whereas symptomatic disease requires surgery, rigid or flexible bronchoscopic removal. Recent reports have shown that flexible bronchoscopy can be a safe and effective option for removal of loose in addition to partially imbedded broncholiths. We present a case of a 65-yearold man with chronic cough that underwent successful cryotherapy assisted bronchoscopic removal of an imbedded broncholith. We will also review current literature regarding the management broncholithiasis.

    Experimenatal results on the development of a Laser-Induced Fluorescence Bronchoscopy(LIFB) for the detection and localization of early lung cancer are reported in this paper. The system utilizes fluorescence of photosensitizer drug to provide real time video imaging for the examined lung tissue. Color filters are used to differentiate signal from background and a computer image processing technique is also applied to subtract the background. Moreover, a pseudocolor contrast enhancement method was developed to enhance the fluorescence image displayed on the vidio monitor. Suspicious areas are identified by pseudocolor image to guide biopsy, and several clinical trials show that sensitivity and contrast capability of the system should permit the detection and localization of early lung cancer.

  18. [Rationale for using nabumetone and clinical experience].

    Roth, S H

    2000-01-01

    Nabumetone's position as one of the most commonly used nonsteroidal anti-inflammatory drugs (NSAIDs) in the world today is based upon over a decade of clinical experience. The popularity of this drug lies in both its unique pharmacokinetic profile and special safety features in pharmacodynamic terms. This nonacidic prodrug with an active 6-methoxy-2-naphthylacetic acid (6-MNA) metabolite has COX-2 preferential features and is also devoid of enterohepatic recirculation. It is felt that these characteristics have provided the basis for its unique long term tolerability, documented in various at-risk osteoarthritis and rheumatoid arthritis populations. The excellent tolerability of nabumetone and its 24-hour half-life, which provides the advantages of a once-daily dosage regimen, make it uniquely suitable for long term anti-inflammatory therapy in arthritis. The tolerability profile of nabumetone has also demonstrated clear cost-effectiveness advantages, as confirmed by comparative and epidemiological studies. Selective COX-2 NSAIDs are likely to prove more expensive because of the increasing costs and demands of clinical research prior to FDA approval. These higher costs may limit and influence patient access, depending on the healthcare delivery system, and many years of experience will be required to document the putative tolerability advantages of these newer COX-2 inhibitor agents. In the meantime, it is comforting that nabumetone has established such an advantageous tolerability profile together with acknowledged efficacy.

    Samuel W Jones

    Full Text Available BACKGROUND: Acute lung injury (ALI is a major factor determining morbidity following burns and inhalational injury. In experimental models, factors potentially contributing to ALI risk include inhalation of toxins directly causing cell damage; inflammation; and infection. However, few studies have been done in humans. METHODS: We carried out a prospective observational study of patients admitted to the NC Jaycees Burn Center who were intubated and on mechanical ventilation for burns and suspected inhalational injury. Subjects were enrolled over an 8-month period and followed till discharge or death. Serial bronchial washings from clinically-indicated bronchoscopies were collected and analyzed for markers of cell injury and inflammation. These markers were compared with clinical markers of ALI. RESULTS: Forty-three consecutive patients were studied, with a spectrum of burn and inhalation injury severity. Visible soot at initial bronchoscopy and gram negative bacteria in the lower respiratory tract were associated with ALI in univariate analyses. Subsequent multivariate analysis also controlled for % body surface area burns, infection, and inhalation severity. Elevated IL-10 and reduced IL-12p70 in bronchial washings were statistically significantly associated with ALI. CONCLUSIONS: Independently of several factors including initial inhalational injury severity, infection, and extent of surface burns, high early levels of IL-10 and low levels of IL-12p70 in the central airways are associated with ALI in patients intubated after acute burn/inhalation injury. Lower airway secretions can be collected serially in critically ill burn/inhalation injury patients and may yield important clues to specific pathophysiologic pathways.

    2006-08-01

    Undergraduate clinical orthodontic experience may be expressed in a variety of ways. The most common way (used, inter alia, in the DentEd school visits) is by number of curriculum hours. Other ways include the number of patients seen, or number of procedures carried out. Whilst any of these methods may allow comparison between cohorts of students within a school or between schools, none of them are suitable to determine how much experience is 'satisfactory', nor do they indicate what the student should know, understand, or be able to do, to be considered 'satisfactory', and hence fit to graduate. This situation may be addressed by the use of competences and/or learning outcomes, and in 2004 the Association for Dental Education in Europe (ADEE) adopted a document that contained one major competence and five supporting competences in orthodontics. This paper considers the shortcomings of conventional methods of recording orthodontic experience in relation to the acquisition of these competences, and some ways in which staff and students may assess competence.

    In bronchoschopy, computer vision systems for navigation assistance are an attractive low-cost solution to guide the endoscopist to target peripheral lesions for biopsy and histological analysis. We propose a decoupled deep learning architecture that projects input frames onto the domain of CT renderings, thus allowing offline training from patient-specific CT data. A fully convolutional network architecture is implemented on GPU and tested on a phantom dataset involving 32 video sequences and [Formula: see text]60k frames with aligned ground truth and renderings, which is made available as the first public dataset for bronchoscopy navigation. An average estimated depth accuracy of 1.5 mm was obtained, outperforming conventional direct depth estimation from input frames by 60%, and with a computational time of [Formula: see text]30 ms on modern GPUs. Qualitatively, the estimated depth and renderings closely resemble the ground truth. The proposed method shows a novel architecture to perform real-time monocular depth estimation without losing patient specificity in bronchoscopy. Future work will include integration within SLAM systems and collection of in vivo datasets.

    Full Text Available To evaluate the occurrence of electrocardiographic abnormalities during fiberoptic bronchoscopy, in relation to specific stages of the procedures, patients′ age, sex, smoking, pre-existing lung disease, premedication and oxygen saturation, a prospective study was conducted on 56 patients aged 35 to 75 (mean 62 years without pre-existing cardiovascular disease. Patients were connected to a 12-lead computerized electrocardiographic recorder and pulse oximeter. Fall of oxygen saturation from mean of 95.12% before the procedure to below 80% was observed in 12 (21.4% patients and below 75% in 5 (8.9% patients, at various stages. Statistically highly significant (p < 0.001 fall of oxygen saturation was observed during the procedures while bronchoscope was introduced into the airways and tracheobronchial tree examined. Major disturbances of cardiac rhythm (i.e. atrial, ventricular or both developed in 23 (41.07% patients. Out of these, sinus tachycardia was noted in 16 (69.5%, ventricular premature complexes in 5 (21.7% and paroxysmal supraventricular tachycardia in 2 (8.6% patients. Arrhythmias were most frequent in association with periods of maximum oxygen desaturation in 18 (78.2% of these 23 patients. Oxygen desaturation persisted for more than half an hour in 38 (67.8% of the 56 patients. However, no correlation was observed between the frequency of arrhythmias during bronchoscopy and patients′ age, sex pre-medication or pre-existing pulmonary disease.

  5. High dynamic range (HDR) virtual bronchoscopy rendering for video tracking

    Popa, Teo; Choi, Jae

    2007-03-01

    In this paper, we present the design and implementation of a new rendering method based on high dynamic range (HDR) lighting and exposure control. This rendering method is applied to create video images for a 3D virtual bronchoscopy system. One of the main optical parameters of a bronchoscope's camera is the sensor exposure. The exposure adjustment is needed since the dynamic range of most digital video cameras is narrower than the high dynamic range of real scenes. The dynamic range of a camera is defined as the ratio of the brightest point of an image to the darkest point of the same image where details are present. In a video camera exposure is controlled by shutter speed and the lens aperture. To create the virtual bronchoscopic images, we first rendered a raw image in absolute units (luminance); then, we simulated exposure by mapping the computed values to the values appropriate for video-acquired images using a tone mapping operator. We generated several images with HDR and others with low dynamic range (LDR), and then compared their quality by applying them to a 2D/3D video-based tracking system. We conclude that images with HDR are closer to real bronchoscopy images than those with LDR, and thus, that HDR lighting can improve the accuracy of image-based tracking.

    BACKGROUND:The past several decades have witnessed increasingly successful rates of liver transplantation. However, retransplantation remains the only choice for patients with irreversible graft failure after primary transplantation. This article aimed to summarize our clinical experience in liver retransplantation. METHODS:From June 2002 to December 2005, a total of 185 cases of liver transplantation including 8 cases of retransplantation were performed in our hospital. The clinical data were analyzed retrospectively. RESULTS:The rate of liver retransplantation was 4.32%. Retransplantation was indicated for the following reasons:biliary complication (3 cases), chronic rejection (2), hepatic artery thrombosis (1), uncontrollable acute rejection (1) and hepatitis B recurrence (1). The mean model of end-stage liver disease (MELD) scores before primary transplantation and retransplantation were 15.6 and 23.9, respectively (P CONCLUSIONS:Liver retransplantation is the only means of saving the patient with hepatic allograft failure. Understanding of the indications for retransplantation, careful selection of operation timing, excellent surgical skills and meticulous postoperative management all contribute to the success of each case of retransplantation.

    While amphotericin B deoxycholate (Fungizone, Apothecon Pharmaceuticals) has been considered by many to be the gold standard for the treatment for numerous invasive fungal infections for over 45 years, toxicities associated with its use often necessitate treatment modification or discontinuation. Lipid-based formulations, including liposomal amphotericin B (AmBisome, Fujisawa Healthcare, Inc.), were developed to decrease many of these toxicities while retaining broad antifungal spectrum and potency of amphotericin B. In clinical trials, liposomal amphotericin B has demonstrated efficacy comparable to that of amphotericin B deoxycholate while reducing the incidence of treatment-related nephrotoxicity, electrolyte-wasting, and infusion-related reactions. In addition, recent clinical trials have also compared liposomal amphotericin B with other antifungal classes. Acquisition costs of liposomal amphotericin B are substantially higher than those of amphotericin B deoxycholate and other antifungals. While pharmacoeconomic analyses consider outcomes and other treatment-related costs, they have yet to clearly demonstrate the cost-effectiveness of liposomal amphotericin B when compared with amphotericin B deoxycholate or other antifungal agents. This review will focus primarily on recent liposomal amphotericin B experience and attempt to put its use into perspective considering other available antifungal agents.

    Being a member of the Flight Medicine Clinic (FMC) Staff is a great experience. I joined the FMC staff 2 years ago when I became part of the Kelsey-Seybold team. The FMC staff consists of Flight Surgeons, Family Clinic Physician, Nursing staff, Wellness Coordinator and Support staff. We serve as the Primary Care Physicians for the astronauts and their families and provide annual physicals for the retired astronauts. We have approximately 800 patients in the FMC. As the Family Clinic Physician, I care for the astronaut spouses and children and provide annual physicals for the retired astronauts. Since we have a small patient population, we have the opportunity to spend increased personal time with our patients, which I enjoy. We have a pretty healthy patient population, who are very interested in their overall health and preventive care. In preparation for a shuttle launch, our nursing staff assists the flight surgeons with the astronaut physical exams, which occur 10 days prior to launch and again 3 days after their return. We also provide Primary Contact physicals for the families and guests, who will be in close contact with shuttle crew members. During these physicals, we provide education, emphasizing the importance of preventing the spread of communicable diseases to shuttle crew members. Being a part of the Space Medicine Program is an honor. To know that you contribute in some way to our nation s Space Program is very special.

    Since October 1986, we have had experience with 96 Sarns centrifugal pumps in 72 patients (pts). Heparinless left atrial to femoral artery or aorta bypass was used in 14 pts undergoing surgery on the thoracic aorta with 13 survivors (93%). No paraplegia or device-related complications were observed. In 57 patients, the Sarns centrifugal pump was used as a univentricular (27 pts) or biventricular (30 pts) cardiac assist device for postcardiotomy cardiogenic shock. In these patients, cardiac assist duration ranged from 2 to 434 h with a hospital survival rate of 29% in those requiring left ventricular assist and 13% in those requiring biventricular assist. Although complications were ubiquitous in this mortally ill patient population, in 5,235 pump-hours, no pump thrombosis was observed. Hospital survivors followed for 4 months to 6 years have enjoyed an improved functional class. We conclude that the Sarns centrifugal pump is an effective cardiac assist device when used to salvage patients otherwise unweanable from cardiopulmonary bypass. Partial left ventricular bypass using a centrifugal pump has become our procedure of choice for unloading the left ventricle and for maintenance of distal aortic perfusion pressure when performing surgery on the thoracic aorta. This clinical experience with the Sarns centrifugal pump appears to be similar to that reported with other centrifugal assist devices.

    Full Text Available OBJECTIVE: To analyze the initial clinical experience of transmyocardial laser revascularization (TMLR in patients with severe diffuse coronary artery disease. METHODS: Between February, 1998 and February, 1999, 20 patients were submitted to TMLR at the Heart Institute (InCor, University of São Paulo Medical School, Brazil, isolated or in association with conventional coronary artery bypass graft (CABG. All patients had severe diffuse coronary artery disease, with angina functional class III/IV (Canadian Cardiovascular Society score unresponsive to medical therapy. Fourteen patients were submitted to TMLR as the sole therapy, whereas 6 underwent concomitant CABG. Fifty per cent of the patients had either been previously submitted to a CABG or to a percutaneous transluminal coronary angioplasty (PTCA. Mean age was 60 years, ranging from 45 to 74 years. RESULTS: All patients had three-vessel disease, with normal or mildly impaired left ventricular global function. Follow-up ranged from 1 to 13 months (mean 6.6 months, with no postoperative short or long term mortality. There was significant symptom improvement after the procedure, with 85% of the patients free of angina, and the remaining 15 % of the patients showing improvement in functional class, as well as in exercise tolerance. CONCLUSION: This novel technique can be considered a low risk alternative for a highly selected group of patients not suitable for conventional revascularization procedures.

    Full Text Available Abstract Introduction Methemoglobinemia is a rare cause of hypoxemia, characterized by abnormal levels of oxidized hemoglobin that cannot bind to and transport oxygen. Case presentation A 62-year-old male underwent bronchoscopy where lidocaine oral solution and Hurricaine spray (20% benzocaine were used. He developed central cyanosis and his oxygen saturation was 85% via pulse oximetry. An arterial blood gas revealed pH 7.45, PCO2 42, PO2 282, oxygen saturation 85%. Co-oximetry performed revealed a methemoglobin level of 17.5% (normal 0.6–2.5%. The patient was continued on 15 L/minute nonrebreathing face mask and subsequent oxygen saturation improved to 92% within two hours. With hemodynamic stability and improved SpO2, treatment with methylene blue was withheld. Conclusion Methemoglobinemia is a potentially lethal condition after exposure to routinely used drugs. Physicians should be aware of this complication for early diagnosis and treatment.

    Full Text Available Tracheal or bronchial proximal stenoses occur as complications in 20–30% of lung cancers, resulting in a dramatic alteration in quality of life and poor prognosis. Bronchoscopic management of these obstructions is based on what are known as “thermal” techniques for intraluminal stenosis and/or placement of tracheal or bronchial prostheses for extrinsic compressions, leading to rapid symptom palliation in the vast majority of patients. This invasive treatment should only be used in cases of symptomatic obstructions and in the presence of viable bronchial tree and downstream parenchyma. This review aims to clarify 1 the available methods for assessing the characteristics of stenoses before treatment, 2 the various techniques available including their preferred indications, outcomes and complications, and 3 the integration of interventional bronchoscopy in the multidisciplinary management of proximal bronchial cancers and its synergistic effects with the other specific treatments (surgery, radiotherapy or chemotherapy.

    Full Text Available Aim: In this study, we aimed to investigate the effect of written informed consent and comprehensive multimedia information on the anxiety level of patients, consumption of sedatives, difficulties during bronchoscopy, complications and duration of procedure. Methods: 150 patients undergoing bronchoscopy were included to this study. They were randomized into two groups Multimedia information group (MIG, n = 75 and written-informed consent group (WICG, n = 75. Signed written informed consent was obtained from all patients. Patients in MIG group watched comprehensive multimedia presentation. State anxiety scores of all patients were evaluated with State and Trait anxiety inventory (STAI-S. Results: STAI-S score of patients in MIG (40.31 ± 8.08 was lower than patients in WICG (44.29 ± 9.62 (P = 0.007. Satisfaction level was higher in MIG (P = 0.001. Statistically higher difficulties during "passage through vocal cords" and "interventions during bronchoscopy" were present in WICG group (P = 0.013 and P = 0.043, respectively. Total midazolam dose during bronchoscopy, and duration of bronchoscopy were statistically lower in MIG patients (P < 0.001 and P = 0.045, respectively. Difficulties during "waiting period", "passage through nasal/oral route", "applications of local anesthesia" and "complication frequency" were similar in both groups. Conclusion: Besides reducing the state anxiety, multimedia information can reduce the dose of sedation, shorten the processing duration and reduce the difficulties during bronchoscopy.

    Full Text Available Abstract There is currently much interest in adult mesenchymal stem cells (MSCs and their ability to differentiate into other cell types, and to partake in the anatomy and physiology of remote organs. It is now clear these cells may be purified from several organs in the body besides bone marrow. MSCs take part in wound healing by contributing to myofibroblast and possibly fibroblast populations, and may be involved in epithelial tissue regeneration in certain organs, although this remains more controversial. In this review, we examine the ability of MSCs to modulate liver, kidney, heart and intestinal repair, and we update their opposing qualities of being less immunogenic and therefore tolerated in a transplant situation, yet being able to contribute to xenograft models of human tumour formation in other contexts. However, such observations have not been replicated in the clinic. Recent studies showing the clinical safety of MSC in several pathologies are discussed. The possible opposing powers of MSC need careful understanding and control if their clinical potential is to be realised with long-term safety for patients.

    Full Text Available OBJECTIVE:Laryngoscopy and stimuli inside the trachea cause an intense sympatho-adrenal response. Remifentanil seems to be the optimal opioid for rigid bronchoscopy due to its potent and short-acting properties. The purpose of this study was to compare bolus propofol and ketamine as an adjuvant to remifentanil-based total intravenous anesthesia for pediatric rigid bronchoscopy.MATERIALS AND METHODS:Forty children under 12 years of age who had been scheduled for a rigid bronchoscopy were included in this study. After midazolam premedication, a 1 µg/kg/min remifentanil infusion was started, and patients were randomly allocated to receive either propofol (Group P or ketamine (Group K as well as mivacurium for muscle relaxation. Anesthesia was maintained with a 1 µg/kg/min remifentanil infusion and bolus doses of propofol or ketamine. After the rigid bronchoscopy, 0.05 µg/kg/min of remifentanil was maintained until extubation. Hemodynamic parameters, emergence characteristics, and adverse events were evaluated.RESULTS:The demographic variables were comparable between the two groups. The decrease in mean arterial pressure from baseline values to the lowest values during rigid bronchoscopy was greater in Group P (p= 0.049, while the reduction in the other parameters and the incidence of adverse events were comparable between the two groups. The need for assisted or controlled mask ventilation after extubation was higher in Group K.CONCLUSION:Remifentanil-based total intravenous anesthesia with propofol or ketamine as an adjuvant drug along with controlled ventilation is a viable technique for pediatric rigid bronchoscopy. Ketamine does not provide a definite advantage over propofol with respect to hemodynamic stability during rigid bronchoscopy, while propofol seems more suitable during the recovery period.

Clinical courses, toxic effects, complications and treatment approaches were aimed to be presented. Among the patients, 16 were female and 9 were male; the mean age was 42.1 (17-74 years. It was determined that all the cases were admitted to the hospital during working in the field in Eastern Anatolia Region, between the months of May and June, and between the hours of 15:00 to 18:00. When the cases were considered in terms of bitten body part, 15 were bitten from upper extremity and 10 were bitten from lower extremity. Within an hour the patients were admitted to a health facility with the complaints of nausea, pain, numbness, swelling and redness, and patients were transferred to emergency unit approximately within 1 hour (0.5 to 2 hours following the first intervention. Tetanus immunization is administered in all cases as the first intervention. Antivenom was administered to the 9 (36% of the patients in whom steroid, antihistamine and prophylactic antibiotic therapy was given in the intensive care unit. Under the control of infection clinic, antibiotic therapy was initiated to 13 (52% patients in who cellulitis, abscess, lymphedema and compartment syndrome were developed. Healing was observed approximately within 4 days (2-6 days and recovery was observed in all the cases. Patients admitted due to snake bites should be followed closely for at least 6 to 8 hours. According to the patient’s clinical condition and laboratory test results, early intervention therapy should be regulated and antivenom therapy should be administered in the presence of systemic symptoms.

    There is an ongoing search for alternative animal models in research of respiratory medicine. Depending on the goal of the research, large animals as models of pulmonary disease often resemble the situation of the human lung much better than mice do. Working with large animals also offers the opportunity to sample the same animal repeatedly over a certain course of time, which allows long-term studies without sacrificing the animals. The aim was to establish in vivo sampling methods for the use in a bovine model of a respiratory Chlamydia psittaci infection. Sampling should be performed at various time points in each animal during the study, and the samples should be suitable to study the host response, as well as the pathogen under experimental conditions. Bronchoscopy is a valuable diagnostic tool in human and veterinary medicine. It is a safe and minimally invasive procedure. This article describes the intrabronchial inoculation of calves as well as sampling methods for the lower respiratory tract. Videoendoscopic, intrabronchial inoculation leads to very consistent clinical and pathological findings in all inoculated animals and is, therefore, well-suited for use in models of infectious lung disease. The sampling methods described are bronchoalveolar lavage, bronchial brushing and transbronchial lung biopsy. All of these are valuable diagnostic tools in human medicine and could be adapted for experimental purposes to calves aged 6-8 weeks. The samples obtained were suitable for both pathogen detection and characterization of the severity of lung inflammation in the host.

    The porcine model has contributed significantly to biomedical research over many decades. The similar size and anatomy of pig and human organs make this model particularly beneficial for translational research in areas such as medical device development, therapeutics and xenotransplantation. In recent years, a major limitation with the porcine model was overcome with the successful generation of gene-targeted pigs and the publication of the pig genome. As a result, the role of this model is likely to become even more important. For the respiratory medicine field, the similarities between pig and human lungs give the porcine model particular potential for advancing translational medicine. An increasing number of lung conditions are being studied and modeled in the pig. Genetically modified porcine models of cystic fibrosis have been generated that, unlike mouse models, develop lung disease similar to human cystic fibrosis. However, the scientific literature relating specifically to porcine lung anatomy and airway histology is limited and is largely restricted to veterinary literature and textbooks. Furthermore, methods for in vivo lung procedures in the pig are rarely described. The aims of this review are to collate the disparate literature on porcine lung anatomy, histology, and microbiology; to provide a comparison with the human lung; and to describe appropriate bronchoscopy procedures for the pig lungs to aid clinical researchers working in the area of translational respiratory medicine using the porcine model.

    Background Spray cryotherapy (SCT) was initially developed for gastroenterology (GI) endoscopic use in the esophagus. In some institutions where a device has been utilized by GI, transition to use in the airways by pulmonologists and thoracic surgeons occurred. Significant differences exist, however, in the techniques for safely using SCT in the airways. Methods We describe the early experience at Walter Reed National Military Medical Center from 2011 to 2013 using SCT in patients with malignant airway disease and the evolution of our current techniques and clinical practice patterns for SCT use in patients. In November 2013 enrollment began in a multi-institutional prospective SCT registry in which we are still enrolling and will be reported on separately. Results Twenty-seven patients that underwent 80 procedures (2.96 procedures/patient). The average age was 63 years with a range of 20 to 87 years old. The average Eastern Cooperative Oncology Group (ECOG) status was 1.26. All malignancies were advanced stage disease. All procedures were performed in the central airways. Other modalities were used in combination with SCT in 31 (39%) of procedures. Additionally 45 of the 80 (56%) procedures were performed in proximity to a silicone, hybrid, or metal stent. Three complications occurred out of the 80 procedures. All three were transient hypoxia that limited continued SCT treatments. These patients were all discharged from the bronchoscopy recovery room to their pre-surgical state. Conclusions SCT can be safely used for treatment of malignant airway tumor (MAT) in the airways. Understanding passive venting of the nitrogen gas produced as the liquid nitrogen changes to gas is important for safe use of the device. Complications can be minimized by adopting strict protocols to maximize passive venting and to allow for adequate oxygenation in between sprays. PMID:26807288

Emphasis is placed on the role of the objective sleep study - polysomnography. The use of the current hypnotics belonging to a three Zs group and the minimization of administration of benzodiazepines are most important in pharmacotherapy for insomnia. The results of a clinical polysomnographic study of the effect of Zolpidem (Sanval in patients with insomnia are presented. The subjective evaluation of the beneficial effect of a 10-day course of Sanval is confirmed by the objective studies of the sleep pattern undergoing positive changes in the most important indicators, such as the process of falling asleep, the time of intrasleep awakenings, and the duration of Δ-sleep. The high safety and good tolerability of Sanval permit the latter to be assessed as an effective agent for the treatment of insomnia.

    The principle of action of sensitizers with electron affinity is explained and the development of these radiosensitizing substances up to the clinical of Misonidazol (MIS; Ro-07-0582) is shown. With special regard to the pharmacokinetic action of this substance, the therapeutic effects of MIS were examined in ten patients with brain tumors of high malignancy (400 mg/m/sup 2/) and four patients with oesophageal carcinomas (1 g/m/sup 2/), all these patients having reached the clinical phase III. Four other patients with recurrent brain tumors received a dose of 1 g/m/sup 2/ of MIS before each irradiation. Apart from slight neurotoxic and gastrointestinal side effects, the applicated doses of MIS were generally well tolerated. Only in one case a generalized maculopapular exanthema developed which regressed completely within few days. No correlation could be found between the subjective side effects and the plasma values determined by means of high pressure liquid chromatography (HPLC). After one to four hours following oral application, the maximum plasma concentrations were measured, the half-life (T 1/2) varying in all patients between five and ten hours. It was not possible to demonstrate an influence of dexamethasone on the plasma concentration of half-life of MIS in the brain tumor patients. The cerebrospinal fluid concentrations of MIS which may be used as an index for the concentrations in brain tumors, are closely correlated with the corresponding plasma values. There was no correlation between MIS concentrations in plasma and saliva, so that the determination of MIS in the saliva cannot be recommended as a routine method for control examinations.

    The availability of newer, more sophisticated and versatile bronchoscopes has expanded the spectrum and scope of the indications for bronchoscopy in the newborn infant both for diagnostic and therapeutic purposes. The aim of this study was to carry out a retrospective analysis of the bronchoscopies performed on newborn infants, and to review the indications of this procedure in this age group. Sixty-three patients were submitted to 67 bronchoscopies in a period of 13 years, allowing the diagnosis of 45 anomalies and malformations of the tracheo-bronchial tree, and the performance of 24 bronchoalveolar lavages. In six cases, endoscopic removal of secretions helped to resolve resistant atelectasia, while in another case, with esophageal atresia, intra-operative definition of the fistula tract was possible through catheterisation of the fistula with the bronchoscope. The flexible bronchoscope was preferred for diagnosis by direct visualisation, and the rigid bronchoscope for some diagnostic and therapeutic procedures. Stridor, unexplained cyanosis, hemoptysis, persistent or recurrent pulmonary images, difficulties in the intubation or extubation, and persistent disturbances in ventilation are among the main indications for bronchoscopy in the newborn infant. Bronchoscopy also allows the performance of subsidiary techniques, such as bronchoalveolar lavage, biopsy and laser therapy.

    Aim of the study To analyse the incidence of appendiceal neuroendocrine neoplasms in appendectomy specimens and establish the epidemiological and histopathological features, treatment, and clinical course. Material and methods Between 2004 and 2013, 975 patients who underwent appendectomy in Ankara Oncology Education and Research Hospital were retrospectively analysed. Results Neuroendocrine neoplasm was detected in the nine of 975 (0.9%) patients. Neuroendocrine neoplasms were diagnosed in eight patients by appendectomy, which was performed because of the prediagnosis of acute appendicitis, and in one patient by the suspicious mass detection during surgical procedures that were done in the appendix for a different reason. Eight of the patients’ tumours were in the tip of the appendix, and one of the patients’ tumours was at the base of appendix. Tumour size in 77.8% of patients was equal or less than 1 cm, in 22.2% patients it was 1–2 cm. There was tumour invasion in the muscularis propria layer in four patients, in the serosa layer in three patients, and in the deep mesoappendix in two patients. Patients were followed for a median of 78 months. In the follow-up of patients who were operated because of colon cancer, metachronous colon tumour evolved. This patient died due to progressive disease. Other patients are still disease-free. Conclusions The diagnosis of neuroendocrine neoplasm is often incidentally done after appendectomy. Tumour size is important in determining the extent of disease and in the selection of the surgical method during operation. PMID:26793027

  13. Cartap hydrochloride poisoning: A clinical experience

    Full Text Available Cartap hydrochloride, a nereistoxin analog, is a commonly used low toxicity insecticide. We describe a patient who presented to the emergency department with alleged history of ingestion of Cartap hydrochloride as an act of deliberate self-harm. The patient was managed conservatively. To our knowledge this is the first case report of Cartap hydrochloride suicidal poisoning. Cartap toxicity has been considered to be minimal, but a number of animal models have shown significant neuromuscular toxicity resulting in respiratory failure. It is hypothesized that the primary effect of Cartap hydrochloride is through inhibition of the [ 3 H]-ryanodine binding to the Ca 2+ release channel in the sarcoplasmic reticulum in a dose-dependent manner and promotion of extracellular Ca 2+ influx and induction of internal Ca 2+ release. This results in tonic diaphragmatic contraction rather than paralysis. This is the basis of the clinical presentation of acute Cartap poisoning as well as the treatment with chelators namely British Anti Lewisite and sodium dimercaptopropane sulfonate.

    Double filtration plasmapheresis, one kind of fractionation plasmapheresis, was developed from membrane type plasmapheresis to remove only the pathogen and return the normal protein back to the patient. We started our automated double filtration plasmapheresis since December 1993. There were 13 patients who received one hundred treatments totally during one year period. And they are myasthenia gravis (8 patients); acute inflammatory demyelinating polyneuropathy (1 patient), multiple myeloma (1 patient); acquired factor VIII inhibitor (1 patient); autoimmune hemolytic anemia (1 patient); systemic lupus erythematous (1 patient). Technically double filtration plasmapheresis is easy to perform and time-saving. It also makes necessity of replacement fluid less frequent. Incidence of complication is rare, and this includes hypotension 2%, palpitation 1%, headache 1%, hemolysis 4%, air emboli 1%, high secondary pressure 2%, and no motality during our treatment. Clinical response is documented in cases of myasthenia gravis; acute inflammatory demyelinating polyneuropathy and acquired factor VIII inhibitor in our study. In conclusion, double filtration plasmapheresis is a time-saving, convenient, and safe therapeutic modality with rare complication. Because its effectiveness on limited kinds of diseases and costs relatively high price, thus plasmapheresis should be used in selected cases and treat aggressively if indicated.

    Lower urinary tract symptoms (LUTS) suggestive of benign prostatic obstruction are common in aging men. Nearly 25% of men >40 years of age have LUTS. Medical therapy with alpha-blockade is the most common method of medical therapy for benign prostatic obstruction. Multiple methods of minimally invasive surgical therapies have been introduced in the last decade. These methods include balloon dilatation, temporary and permanent urethral stents, various laser techniques, microwave thermotherapy, transurethral needle ablation, electrovaporization, and high-intensity focused ultrasound. alpha-Receptor blockers to reduce the sympathetic tone of the prostate are considered as first-line therapy to relieve the symptoms of benign prostatic hyperplasia. Selective alpha(1)-receptor blockers relax prostatic smooth muscle, relieve bladder outlet obstruction, and enhance urine flow with fewer side effects. In addition, it was determined that treating patients with alpha-blockers increases prostatic apoptosis. Pharmacokinetic activity, mode of action, clinical efficacy, and side effects of the selective alpha(1)-receptor blockers terazosin, doxazosin, and prazosin are reviewed.

    Full Text Available Abstract T cell disorders have been poorly understood until recently. Lack of knowledge of underlying molecular mechanisms together with incomplete data on long term outcome have made it difficult to assess prognosis and give the most effective treatment. Rapid progress in defining molecular defects, improved supportive care and much improved results from hematopoietic stem cell transplantation (HSCT now mean that curative treatment is possible for many patients. However, this depends on prompt recognition, accurate diagnosis and careful treatment planning. This review will discuss recent progress in our clinical and molecular understanding of a variety of disorders including: severe combined immunodeficiency, specific T cell immunodeficiencies, signaling defects, DNA repair defects, immune-osseous dysplasias, thymic disorders and abnormalities of apoptosis. There is still much to discover in this area and some conditions which are as yet very poorly understood. However, with increased knowledge about how these disorders can present and the particular problems each group may face it is hoped that these patients can be recognized early and managed appropriately, so providing them with the best possible outcome.

    Prior research has suggested that clinical experience for nursing students is stressful. Concern about making an error and harming the patient, limited knowledge and skills for practice, and difficulties in interacting with the teacher and others in the clinical setting are some of the stressors reported by students. Few studies have compared these stresses and the clinical experiences in general between students in associate degree (ADN) and baccalaureate (BSN) nursing programs. The purposes of this research were to compare the clinical experiences of ADN and BSN students at different levels in the programs and describe these experiences from the students' perspectives. As such, both quantitative and qualitative data were collected from 415 students in ADN and BSN programs in the Midwest. The ADN students reported significantly higher stress in clinical practice than BSN students (t = 2.16, p ADN and BSN students in clinical practice increased as they progressed through the programs. The semester prior to graduation was the most stressful time in terms of clinical practice for both ADN and BSN students. The instructor was the predominant stressor reported by students in ADN programs across all levels of the curriculum. Among BSN students, the most prevalent stresses were coping with demands associated with patient care and the clinical teacher. The findings highlight the important role of the clinical faculty in both types of nursing programs.

    Prometheus is a new extracorporeal liver support device which facilitates the combined removal of both albumin-bound and water-soluble toxins based upon the method of fractionated plasma separation and adsorption (FPSA). The pilot trial included 11 patients with acute-on-chronic liver failure and concomitant renal failure. Prometheus therapy was found to be safe except for a reversible decrease of blood pressure. In three patients, clotting of the secondary system occurred. Prometheus treatment significantly improved blood levels of protein-bound (conjugated bilirubin, bile acids, ammonia) and water-soluble (creatinine, urea) substances. Thus, Prometheus might be a new therapeutic option in patients with severe hepatorenal syndrome. Furthermore, there is some preliminary experience with Prometheus in the treatment of refractory cholestatic pruritus and in successful bridging to liver transplantation. In order to compare extraction capacities of Prometheus and the molecular adsorbent recirculating system (MARS), five patients were crossover-treated with both systems. Prometheus resulted in significantly higher reduction ratios of bilirubin, ammonia and urea. Another study closely monitored whether the device causes an unselective removal. Neither important cytokines nor coagulation factors were found to be removed. In conclusion, Prometheus seems to be a new therapeutic option in artificial liver support. A significant improvement of the biochemical milieu was already observed after two treatments. The potential to remove protein-bound and water-soluble substances has been shown without signs of a significant unselective removal.

    Full Text Available Introduction: In this environment, previous workers have reported on the challenges of managing large sized ameloblastoma of the jaws with less than adequate facilities. The aim of this review is to present the management of 68 cases of ameloblastoma with emphasis on surgical care. Materials and Methods: Retrospective survey of case notes of patients with histopathologic diagnosis of ameloblastoma (using the criteria of Barnes et al., 2005 seen between January 2006 and August 2010 at the Maxillofacial Unit, Ahmadu Bello University Teaching Hospital, Shika-Zaria, Nigeria was undertaken. Data collected includes histopathological diagnosis, age, gender, clinical information on site of lesion, form of intubation and surgical procedure performed. Results: Out of 94 patients, 68 with histological diagnosis of ameloblastoma (59 mandibular and 9 maxillary were operated within the study period. The remainder (26 was not treated in hospital. Among 68 patients treated, more were males (38 than females (30, giving a male to female ratio of 1.3:1. The age range was between 14 and 74 years (mean-standard deviation. The duration of the symptoms ranged from 7 months to 24 years, most were follicular ameloblastoma (n = 13 followed by acanthomatous type (n = 7. Endotracheal intubation was the most common (n = 55 followed by fiber optic laryngoscopy (n = 8. The surgical approach most used was extended Risdon with intraoral (n = 24 followed by extended Risdon with lip split and intraoral (n = 17. Segmental resection (en block formed the bulk of our procedures (n = 22 followed by subtotal mandibulectomy (n = 16. Conclusion: The treatment of ameloblastoma remains controversial. Its destructive nature has left patients with wide defects difficult to reconstruct.

    AIM: To evaluate the clinic features of eosinophilicgastroenteritis and to examine the diagnosis, treatment,long-term outcome of this disease.METHODS: Charts with a diagnosis of eosinophilicgastroenteritis from 1984 to 2002 at Mackay Memorial Hospital were reviewed retrospectively. There were 15 patients diagnosed with eosinophilic gastroenteritis. The diagnosis was established in 13 by histologic evaluation of endoscopic biopsy or operative specimen and in 2 by radiologic imaging and the presence of eosinophilic ascites.RESULTS: All the patients had gastrointestinal symptoms and 12 (80 %) had hypereosinophilia (absolute eosinophil count 1 008 to 31 360/cm3). The most common symptoms were abdominal pain and diarrhea. Five of the 15 patients had a history of allergy. Seven patients had involvement of the mucosa, 2 of muscularis, and 6 of subserosa. One with a history of seafood allergy was successfully treated with an elimination diet. Another patient improved spontaneously after fasted for several days. The remaining 13 patients were treated with oral prednisolone, 10 to 40 mg/day initially,which was then tapered. The symptoms in all the patients subsided within two weeks. Eleven of the 15 patients were followed up for more than 12 months (12 to 104 months,mean 48.7), of whom 5 had relapses after discontinuing steroids (13 episodes). Two of these patients required longterm maintenance oral prednisolone (5 to 10 mg/day).CONCLUSION: Eosinophilic gastroenteritis is a rare condition of unclear etiology characterized by relapses and remissions. Short courses of corticosteroids are the mainstay of treatment, although some patients with relapsing disease require long-term low-dose steroids.

    gas distribution with a long time constant. After 5±1-day 3LV, the patients were switched to PS ventilation; after gradually reduction of ventilation maintenance, they were disconnected from a ventilator and transferred to a specialized unit. Conclusion. The small study group made it impossible to statistically assess outcomes; the clinical results are not at least contrary to the results of theoretical mathematic simulation of 3LV in mathematical and physical models. 3LV as compared with PCV applied within the first 2—4 hours of AV improved lung gas exchange. It can be a promising mode of ventilation for the lungs afflicted by a diffusive non-homogenous pathological process. Key words: artificial ventilation, three-level ventilation, acute lung injury, acute respiratory distress syndrome.

    Full Text Available Background : Diagnosis of sputum/smear-negative pulmonary tuberculosis patients can be both challenging and time consuming with many patients being put on empirical anti-tubercular treatment. Fibreoptic bronchoscopy may provide a confirmative and early diagnosis in such patients. Aims: To assess the role of fibreoptic bronchoscopy in the diagnosis of sputum /smear-negative pulmonary tuberculosis. Materials and Methods: The study was conducted on 75 suspected sputum / smear-negative pulmonary tuberculosis cases attending Pulmonary Medicine Department of Mamata Medical College and Hospital, Khammam, AP. Fibreoptic bronchoscopy was performed; culture of sputum and bronchial washings for Mycobacterium tuberculosis was done by BACTEC method. Results: A final diagnosis of sputum /smear-negative pulmonary tuberculosis was made in 60 patients. Bronchial washings smear for acid-fast bacilli (AFB was positive in 21 patients while culture of bronchial washings was positive in 39 patients. In 29 patients, smear or culture of bronchial washing alone contributed to the final diagnosis. Total yield of bronchoscopy in diagnosis of sputum smear negative pulmonary tuberculosis was 83.33% (50/60; bronchoscopy was the only diagnostic method in 66% cases (40/60 with bronchial washings being the only diagnostic method in 48.33%. Bronchial washings smear for AFB and histopathological evidence of caseating granuloma made immediate diagnosis possible in 48.33% (29/60 patients. Conclusion: Our study suggests that fibreoptic bronchoscopy can provide excellent material for diagnosis of suspected cases of Pulmonary Tuberculosis in whom smears of expectorated sputum do not reveal mycobacteria.

    A crucial step for successful percutaneous tracheostomy is the introduction of the needle and guide wire into the trachea. Capnography has recently been proposed as one way to confirm tracheal needle placement. In this randomised controlled study, we used capnography in 26 patients and bronchoscopy in 29 patients to confirm needle placement for percutaneous tracheostomy using Blue Rhino kit. The operating times and the incidence of peri-operative complications were similar for both groups. Capnography proved to be as effective as bronchoscopy in confirming correct needle placement.

    A 62-year-old man with a chronic cough presented with atelectasis of the left upper lobe on chest X-ray. Chest computed tomography showed an atelectasis in the left upper lobe with bronchial wall thickening, stenosis, dilatation, and mucoid impaction. We performed bronchoscopy and found a well-circumscribed mass on the left upper lobe bronchus. The mass was removed by flexible bronchoscopy using an electrosurgical snare and diagnosed with lipoma. An endobronchial lipoma is a rare benign tumor that can be treated by a surgical or endoscopic approach. We report the successful removal of endobronchial lipoma via flexible bronchoscopic electrosurgical snare.

    Three patients suffering from severe, chronic, bronchial asthma underwent bronchoscopy and lavage, using in the irrigant fluid acetylcysteine, isoetharine and Solu-Medrol. All patients had a large amount of thick mucus in the tracheobronchial tree which was removed during the lavage. Following the lavage, all three patients were easily treated with conventional allergic measures and were able to lead normal lives, which they could not do before. A discussion of the precautions to be taken by the medical-surgical team in charge of a patient undergoing bronchoscopy and lavage is made. These conclusions were based on the results of two previous reports by the authors in addition to the present communication.

    In X-ray guided bronchoscopy of peripheral pulmonary lesions, airways and nodules are hardly visible in X-ray images. Transbronchial biopsy of peripheral lesions is often carried out blindly, resulting in degraded diagnostic yield. One solution of this problem is to superimpose the lesions and airways segmented from preoperative 3D CT images onto 2D X-ray images. A feature-based 2D/3D registration method is proposed for the image fusion between the datasets of the two imaging modalities. Two stereo X-ray images are used in the algorithm to improve the accuracy and robustness of the registration. The algorithm extracts the edge features of the bony structures from both CT and X-ray images. The edge points from the X-ray images are categorized into eight groups based on the orientation information of their image gradients. An orientation dependent Euclidean distance map is generated for each group of X-ray feature points. The distance map is then applied to the edge points of the projected CT images whose gradient orientations are compatible with the distance map. The CT and X-ray images are registered by matching the boundaries of the projected CT segmentations to the closest edges of the X-ray images after the orientation constraint is satisfied. Phantom and clinical studies were carried out to validate the algorithm's performance, showing a registration accuracy of 4.19(± 0.5) mm with 48.39(± 9.6) seconds registration time. The algorithm was also evaluated on clinical data, showing promising registration accuracy and robustness.

    Full Text Available OBJECTIVES: There are safety issues associated with propofol use for flexible bronchoscopy (FB. The bispectral index (BIS correlates well with the level of consciousness. The aim of this study was to show that BIS-guided propofol infusion is safe and may provide better sedation, benefiting the patients and bronchoscopists. METHODS: After administering alfentanil bolus, 500 patients were randomized to either propofol infusion titrated to a BIS level of 65-75 (study group or incremental midazolam bolus based on clinical judgment to achieve moderate sedation. The primary endpoint was safety, while the secondary endpoints were recovery time, patient tolerance, and cooperation. RESULTS: The proportion of patients with hypoxemia or hypotensive events were not different in the 2 groups (study vs. control groups: 39.9% vs. 35.7%, p = 0.340; 7.4% vs. 4.4%, p = 0.159, respectively. The mean lowest blood pressure was lower in the study group. Logistic regression revealed male gender, higher American Society of Anesthesiologists physical status, and electrocautery were associated with hypoxemia, whereas lower propofol dose for induction was associated with hypotension in the study group. The study group had better global tolerance (p<0.001, less procedural interference by movement or cough (13.6% vs. 36.1%, p<0.001; 30.0% vs. 44.2%, p = 0.001, respectively, and shorter time to orientation and ambulation (11.7±10.2 min vs. 29.7±26.8 min, p<0.001; 30.0±18.2 min vs. 55.7±40.6 min, p<0.001, respectively compared to the control group. CONCLUSIONS: BIS-guided propofol infusion combined with alfentanil for FB sedation provides excellent patient tolerance, with fast recovery and less procedure interference.

    This study evaluated the prevalence and clinical correlates of abnormal subjective experiences across functional psychotic disorders. Patients were recruited from consecutive admissions with the following diagnoses; schizophrenia (n = 40), schizophreniform disorder (n = 40), schizoaffective disorder (n = 21), mood disorder (n = 18), brief reactive psychosis (n = 15), and atypical psychosis (n = 16). Subjective experiences were assessed using the Frankfurt Complaint Questionnaire (FCQ), and the clinical status was assessed with the Scales for the Assessment of Positive and Negative Symptoms (SAPS and SANS) and the Manual for the Assessment and Documentation of Psychopathology (AMDP). Neither the FCQ total score nor individual subjective experiences displayed significant differences across diagnoses. When the clinical predictors of subjective experiences were studied by multiple regression analyses, a different pattern resulted for individual psychotic disorders. In schizophrenic patients, subjective experiences were predicted by female gender, euphoria, lack of insight, greater illness severity, and more positive symptoms. The only predictors of subjective experiences in the schizophreniform disorder group were the negative symptoms. Within the affective disorders group, subjective experiences had no clinical predictors.

    We describe an innovative program at the University of California, Davis for students to engage in clinical needs finding. Using a team-based approach, students participated in clinical rotations to observe firsthand the needs of clinicians at the university affiliated medical center. The teams were asked to develop documentary-style videos to capture key experiences that would allow future viewers to use the videos as “virtual” clinical rotations. This was conceived as a strategy to allow students in prohibitively large classes, or students in programs at institutions without associated medical or veterinary school programs, to experience clinical rotations and perform needs assessments. The students' perspectives on the experience as well as instructor analysis of best practices for this type of activity are presented and discussed. We found that the internship experience was valuable to the students participating, by not only introducing the practice of needs finding but for increasing the students' confidence in the practice of engineering design and their ability to work independently. The videos produced were of such high quality that instructors from other institutions have requested copies for instructional use. Virtual clinical rotations through video experiences may provide a reasonable substitute for students who do not have the ability to participate in rotations in person. PMID:23483373

    Aim: Latent tuberculosis infections (LTBI) contain a significant reservoir for future epidemics. Screening of health care workers (HCWs) in a high-risk tuberculosis (TB) environment is an important strategy in TB control. The study aimed to assess the prevalence of LTBI among high risk Egyptian HCWs and to assess infection associated risk factors. Methods: Fifty-two HCWs who work at intensive care unit (ICU), bronchoscopy unit, and chest diseases department were tested for LTBI using both tuberculin skin test (TST) and Quantiferon TB Gold in-tube test (QFT). Risk factors for infection, knowledge of HCWs towards different aspects of TB infection and agreement between TST and QFT were also evaluated. Results: Prevalence of LTBI in this study was 13.5% by QFT and TST. It was 13.6% by TST alone and 10.3% by QFT alone. There was good concordance between both tests (Kappa=0.713). There was a statistically significant association between prevalence of LTBI and age of staff ≥30 yr (p=0.002), period of working experience (p=0.006) and working at the Bronchoscopy Unit (p=0.001). The total knowledge of HCWs towards different aspects of TB infection was generally good. Conclusion: Although the participants in the current study were among high risk HCWs, the prevalence of LTBI was low. Bacille Calmette-Guerin (BCG) vaccination, young age, short employment duration, good knowledge and a good infection control were the predictors of low risk of contracting TB at our hospitals. The risk of TB infection in resource-limited countries can be reduced with simple continuous educational and administrative infection control programmes. PMID:27777875

    We aimed to investigate the value of routine flexible bronchoscopy (FB) for the preoperative assessment of early-stage non-small cell lung cancer (NSCLC) diagnosed using percutaneous core needle biopsy (PCNB). We enrolled 688 NSCLC patients who were treated at our hospital between January 2003 and December 2012 and who met the following criteria: (1) early-stage lung cancer (stage I or II); (2) lung cancer had been diagnosed using PCNB; and (3) no evidence of endobronchial disease in the airways other than the primary cancer site on both chest computed tomography (CT) and positron emission tomography-CT (PET-CT). All NSCLC patients were from the same tertiary referral center, where FB is routinely performed preoperatively for this disease, and their medical records were reviewed retrospectively. Of the 688 patients included in the study, 451 (65.6%) were male and the median age was 65 years. Pathology analysis revealed that adenocarcinoma was the most frequently observed cell type (516/688, 75.0%). The distribution of preoperative clinical staging for the 688 patients was (1) IA (54.5%, 375/688); (2) IB (22.1%, 152/688); (3) IIA (18.2%, 125/688); and (4) IIB (5.2%, 36/688). The majority of these patients (95.2%, 655/688) underwent surgical resection. Unsuspected malignant endobronchial lesion on FB was found in only two cases (0.3%), and the surgical strategy had to be modified for both of these patients. Preoperative FB is not beneficial for screening the airways of almost any patient with early-stage NSCLC, provided that neither PET-CT nor CT reveal any evidence of endobronchial malignant involvement other than at the primary cancer site.

    Objective: The aim of this study was to evaluate the clinical value of virtual bronchoscopy (VB) in aiding diagnosis of peripheral lung cancer by transbronchial biopsy (TBB). In addition, we sought to systematically analyze the factors that affect the diagnostic sensitivity of VB-guided TBB for the evaluation of peripheral lung cancers. Materials and methods: A hundred and twenty-two peripheral lung cancers from 122 patients (82 men and 40 women, 38-84 years; median 68.5 years) who were performed VB-guided TBB were evaluated retrospectively. VB was reconstructed from 1- or 0.5-mm slice thickness images of multi-detector CT (MDCT). Experienced pulmonologists inserted the conventional and ultrathin bronchoscopes into the target bronchus under direct vision following the VB image. Results: A definitive diagnosis was established by VB-guided TBB in 96 lesions (79%). The diagnostic sensitivity of small pulmonary lesions {<=}30 mm in maximal diameter (71%) was significantly lower than that of lesions >30 mm (91%, p = 0.008). For small pulmonary lesions {<=}30 mm (n = 76), internal opacity of the lesion was the independent predictor of diagnostic sensitivity by VB-guided TBB, and the non-solid type lung cancers were significantly lower than the solid type and part-solid type lung cancers for diagnostic sensitivity (odds ratio = 0.161; 95% confidence interval = 0.033-0.780; p = 0.023). Conclusion: Use of an ultrathin bronchoscope and simulation with VB reconstructed by high quality MDCT images is thought to improve pathological diagnosis of peripheral lung cancers, especially for solid and partly solid types. For small pulmonary lesions {<=}30 mm, the lesion internal opacity is a significant factor for predicting the diagnostic sensitivity, and the sensitivity was low for small non-solid type of lung cancers.

    Full Text Available Objective: Our objective was to evaluate the educational value of introducing pre-clinical medical students to pediatric patients and their families in a subspecialty clinic setting. Methods: First- and second-year medical students at the University of Michigan seeking clinical experience outside of the classroom attended an outpatient pediatric pulmonary clinic. Evaluation of the experience consisted of pre- and post-clinic student surveys and post-clinic parent surveys with statements employing a four-point Likert scale as well as open-ended questions. Results: Twenty-eight first-year students, 6 second-year students, and 33 parents participated in the study. Post-clinic statement scores significantly increased for statements addressing empathic attitudes, confidence communicating with children and families, comfort in the clinical environment, and social awareness. Scores did not change for statements addressing motivation, a sense of team membership, or confidence with career goals. Students achieved their goals of gaining experience interacting with patients, learning about pulmonary diseases, and observing clinic workflow. Parents felt that they contributed to student education and were not inconvenienced. Conclusions: Students identified several educational benefits of exposure to a single pediatric pulmonary clinic. Patients and families were not inconvenienced by the participation of a student. Additional studies are warranted to further investigate the value of this model of pre-clinical medical student exposure to subspecialty pediatrics.

    Full Text Available Background: Because of airway stimulations during the bronchoscopy and lack of direct access to the airway, preferred method of anesthesia for rigid bronchoscopy is already controversial. In this study we compared inhalation anesthesia with total intravenous anesthesia (TIVA for rigid bronchoscopy. Method and Materials: 30 patients aged 2-6 years were chosen divided on two same groups. Anesthesia in group I maintained with halothane and in group II maintained with remifentanil and propofol. Oxygenation, heart rate, respiratory rate, coughing, bucking, laryngospasm, bronchospasm were evaluated during and after surgery. Also Operation success and surgeon’s satisfaction were recorded as well.Results: Demographic findings were the same in both groups. Oxygenation and heart rate were more stable in group II (P=0.047 and P=0.026 respectively but there was no significant difference in respiratory rate between two groups (P=1. Success rate was also similar in both groups but surgeon’s satisfaction was significantly higher in TIVA (P=0.003. There was not any significant different between complications in two groups. Conclusion: We suggest TIVA for rigid bronchoscopy because of better oxygenation, more homodynamic stability, surgeon’s satisfaction, lack of air pollution and less interference with surgeon’s visual field.

    The objective of this study is to investigate the effects of full airway drainage by fiber bronchoscopy through artificial airway in the treatment of traumatic atelectasis with occult manifestations. From May 2006 to May 2011, 40 cases of occult traumatic atelectasis were enrolled into our prospective study. Group A (n = 18) received drainage by nasal bronchoscope; group B underwent airway drainage by fiber bronchoscopy through artificial airway (n = 22). The effects of treatment were evaluated by the incidence of adult respiratory distress syndrome (ARDS), lung abscess, and the average length of hospital stay. Compared with nasal fiber-optic treatment, airway drainage by fiber bronchoscopy through artificial airway reduced the incidence of ARDS (p = 0.013) and lung abscess (p = 0.062) and shortened the mean length of stay (p = 0.018). Making the decision to create an artificial airway timely and carry out lung lavage by fiber bronchoscopy through artificial airway played a significant role in the treatment of occult traumatic atelectasis.

    Fiber bronchoscopy under local anaesthesia is an examination procedure frequently employed in the remainder of Scandinavia, Europe and USA. It requires only few resources and the costs are considerably less than fiber bronchoscopy under general anaesthesia. Bronchoalveolar lavage (BAL) in connection with fiber bronchoscopy is rapidly undertaken but analysis of the material obtained requires considerable time. A method of induction of local anaesthesia, performance of BAL and preparation of the washings obtained is described. Fiber bronchoscopy and BAL are considered to be safe examination procedures in patients with mild asthma in a stable phase. The examination is only associated with slight discomfort for the patients, who will frequently accept repeated investigations, and complications are rare. BAL is a valuable examination procedure in research and the results have increased the knowledge of mechanisms in a series of interstitial pulmonary diseases. Future investigations of the humoral and cellular components in BAL fluid in asthmatic patients will contribute to increase knowledge of the pathological mechanisms in asthmatic disease.

    Although debriefing in simulation settings is routine in nursing education, debriefing does not routinely take place in clinical settings with nursing students after a patient has died. This pilot study sought to explore nursing students' perceptions of their first experience with the death of a patient. Students reported emotional distress and feelings of inadequacy with regard to communicating with and supporting the family of the dying patient. Only half the students sampled reported debriefing by their clinical instructor or staff. Nurse educators must include debriefing and student support following a patient death in the clinical setting.

  5. High-Flow Nasal Interface Improves Oxygenation in Patients Undergoing Bronchoscopy

    Full Text Available During bronchoscopy hypoxemia is commonly found and oxygen supply can be delivered by interfaces fed with high gas flows. Recently, the high-flow nasal cannula (HFNC has been introduced for oxygen therapy in adults, but they have not been used so far during bronchoscopy in adults. Forty-five patients were randomly assigned to 3 groups receiving oxygen: 40 L/min through a Venturi mask (V40, N=15, nasal cannula (N40, N=15, and 60 L/min through a nasal cannula (N60, N=15 during bronchoscopy. Gas exchange and circulatory variables were sampled before (FiO2 = 0.21, at the end of bronchoscopy (FiO2 = 0.5, and thereafter (V40, FiO2 = 0.35. In 8 healthy volunteers oxygen was randomly delivered according to V40, N40, and N60 settings, and airway pressure was measured. At the end of bronchoscopy, N60 presented higher PaO2, PaO2/FiO2, and SpO2 than V40 and N40 that did not differ between them. In the volunteers (N60 median airway pressure amounted to 3.6 cmH2O. Under a flow rate of 40 L/min both the Venturi mask and HFNC behaved similarly, but nasal cannula associated with a 60 L/min flow produced the better results, thus indicating its use in mild respiratory dysfunctions.

    Percutaneous tracheostomy is a common procedure but varies considerably in approach. The aim of our study was to evaluate the need for intraoperative bronchoscopy and to compare various surgical techniques. During 1 year all percutaneous tracheostomies in three intensive care units were prospectively documented according to a unified protocol. In one unit, bronchoscopy was used routinely and in others only during the study. A total of 111 subjects (77 males) with median age 64 (range, 18-86) years and body mass index 25.4 (range, 15.9-50.7) were included. In unit A, tracheal wall was directly exposed; in unit B, limited dissection to enable tracheal palpation was made. In both units, bronchoscopy was used to check the location of an already inserted guiding needle; needle position required correction in 8% and 12% of cases, respectively. In unit C, in tracheostomies without pretracheal tissue dissection, bronchoscopy was used to guide needle insertion; needle position required correction in 66% of cases. Median duration of operations performed by thoracic surgeons and residents was 10 (range, 3-37) min and by intensive care doctors and residents was 16.5 (range, 3-63) min (p < 0.001). Time from the beginning of preparations for tracheostomy until the end of the whole procedure was median 32 min for bedside tracheostomies and 64 min for operations in the operating theatre (p < 0.001). Limited pretracheal tissue dissection enabled proper guiding needle insertion and bronchoscopy was rarely needed. Percutaneous tracheostomies performed by thoracic surgeons took less time, and duration of the whole procedure was remarkably shorter when performed at bedside.

    This qualitative research in phenomenological design aimed at understanding the meaning of hospital clinical experience in the nurse's training in a Multiprofessional Family Health Residency. The study was developed in a teaching institution. Data collection was based on interviews and had as study population eight resident nurses. I investigated the residents' experience according to their speeches, by making the following guiding question: "Talk about your hospital experience, how does it show itself in your training as a resident"? One open category emerged from the subject' description: Causing to approach the hospital experience and the Primary Health Care. Among the meanings attributed to the hospital experience, there is the need and relevance as an integrant part of the curriculum vitae of the Multiprofessional Family Health Residency for the nurses.

    Clinical learning is an essential component of becoming a nurse. However at times, students report experiencing challenging clinical learning environments (CCLE), raising questions regarding the nature of a challenging clinical learning environment, its impact on students' learning and how students might respond within a CCLE. Using an Interpretive Descriptive study design, researchers held focus groups with 54 students from two Canadian sites, who self-identified as having experienced a CCLE. Students defined a CCLE as affected by relationships in the clinical area and by the context of their learning experiences. CCLE decreased students' learning opportunities and impacted on them as persons. As students determined which relationships were challenging, they tapped other resources and they used strategies to rebuilt, reframe, redirect and/or retreat relative to the specific challenge. Relationships also acted as buffers to unsupportive practice cultures. Implications for practice and research are addressed.

    Stakeholders in e-health such as governance officials, health IT-implementers and vendors have to co-operate to achieve the goal of a future-proof interoperable e-health infrastructure. Co-operation requires knowledge on the responsibility and competences of stakeholder groups. To increase awareness on clinical modeling and standardization we conducted a workshop for Danish and a few Norwegian e-health stakeholders' and made them discuss their views on different aspects of clinical modeling using a theoretical model as a point of departure. Based on the model, we traced stakeholders' experiences. Our results showed there was a tendency that stakeholders were more familiar with e-health requirements than with design methods, clinical information models and clinical terminology as they are described in the scientific literature. The workshop made it possible for stakeholders to discuss their roles and expectations to each other.

    The clinical learning environment is a complex social entity that influences student learning outcomes in the clinical setting. Exploration of this environment gives insight into the educational functioning of the clinical areas and allows nurse teachers to enhance students' opportunities for learning. Since Cyprus is undergoing major reforms in nursing education, building on the experience and knowledge gained, this study aims to explore the present clinical situation and how this would impact on nursing education moves to the university. As nursing education would take on a different approach, it is assumed the learning approach would also be different, and so utilization of the clinical environment would also be improved. Six hundred and forty five students participated in the study. Data were collected by means of the clinical learning environment and supervision instrument. A statistically significant correlation was found between the sub-dimensions "premises of nursing care" and "premises of learning" indicating that students are relating learning environment with the quality of nursing care and patient relationships. The ward atmosphere and the leadership style of the manager were rated as less important factors for learning. The majority of students experienced a group supervision model, but the more satisfied students were those with a "personal mentor" that was considered as the most successful mentor relationship. The findings suggest more thorough examination and understanding of the characteristics of the clinical environment that are conductive to learning. Copyright 2009 Elsevier Ltd. All rights reserved.

  14. Rubrics for clinical evaluation: objectifying the subjective experience.

    Science.gov (United States)

    Isaacson, Julie J; Stacy, Annette S

    2009-03-01

    Rubrics have historically been used in secondary and higher education to evaluate specific assignments or tasks. There is little mention of rubrics in the nursing literature, particularly in the area of clinical evaluation. A strong case can be made for expanding the traditional use of a rubric to include its validity with clinical evaluation. Clinical evaluation remains a challenge, even for seasoned faculty. Faculty and students often interpret clinical course objectives differently. Coupled with this concern is the subjectivity of the evaluation. The use of "novice" clinical faculty, who inevitably struggle with discerning and justifying anything but stellar student performance, further compounds these issues. Rubrics also facilitate the grading experience for faculty and students. Faculty often find themselves making repetitive written comments to students. These comments can be incorporated into the rubric, thus shortening grading time while increasing the quality and quantity of instructor feedback. When clarified in a rubric, course objectives become "real". Student benefits include increased critical thinking and a more realistic approach to self-evaluation. Clinical rubrics can be developed from existing course objectives. Though perhaps tedious in initial development, both faculty and student satisfaction with the clinical evaluation process can be enhanced with the use of rubrics.

    This paper describes the 3-year experience of managing 2 hospital-based dental clinics registered to ISO 9002:1994; it also examines the revision of previous quality management standards in 2 separate institutions to prepare for registration under the new ISO 9001:2000 standard. Daily equipment and process checks, combined with internal audits, were the backbone of the quality system at both locations. Corrective and protective actions had been underused, because of the partial duplication produced by 2 different institutionally mandated risk management and incident reporting systems. ISO 9002 registration provided both dental clinics with responsive quality systems, emphasizing patient satisfaction and providing measurable continuous quality improvement.

    Preceptors play an important role in the process of developing students' knowledge and skills. There is an ongoing search for the best learning and teaching models in clinical education. Little is known about preceptors' perspectives on different models. The aim of the study was to describe nursing preceptors' experiences of two clinical models of clinical education: peer learning and traditional supervision. A descriptive design and qualitative approach was used. Eighteen preceptors from surgical and medical departments at two hospitals were interviewed, ten representing peer learning (student work in pairs) and eight traditional supervision (one student follows a nurse during a shift). The findings showed that preceptors using peer learning created room for students to assume responsibility for their own learning, challenged students' knowledge by refraining from stepping in and encouraged critical thinking. Using traditional supervision, the preceptors' individual ambitions influenced the preceptorship and their own knowledge was empathized as being important to impart. They demonstrated, observed and gradually relinquished responsibility to the students. The choice of clinical education model is important. Peer learning seemed to create learning environments that integrate clinical and academic skills. Investigation of pedagogical models in clinical education should be of major concern to managers and preceptors.

    Full Text Available Abstract Background Shared decision-making has been advocated; however there are relatively few studies on physician preferences for, and experiences of, different styles of clinical decision-making as most research has focused on patient preferences and experiences. The objectives of this study were to determine 1 physician preferences for different styles of clinical decision-making; 2 styles of clinical decision-making physicians perceive themselves as practicing; and 3 the congruence between preferred and perceived style. In addition we sought to determine physician perceptions of the availability of time in visits, and their role in encouraging patients to look for health information. Methods Cross-sectional survey of a nationally representative sample of U.S. physicians. Results 1,050 (53% response rate physicians responded to the survey. Of these, 780 (75% preferred to share decision-making with their patients, 142 (14% preferred paternalism, and 118 (11% preferred consumerism. 87% of physicians perceived themselves as practicing their preferred style. Physicians who preferred their patients to play an active role in decision-making were more likely to report encouraging patients to look for information, and to report having enough time in visits. Conclusion Physicians tend to perceive themselves as practicing their preferred role in clinical decision-making. The direction of the association cannot be inferred from these data; however, we suggest that interventions aimed at promoting shared decision-making need to target physicians as well as patients.

    Full Text Available DNA-abzymes enzymes in autoimmune diseases in clinic and experiment T.E. Naumova, O.M. Durova, A.G. Gabibov, Z.S. Alekberova, S. V. Suchkov DNA-hydrolyzing autoantibodies (AAB or DNA-abzymes can be found in autoimmune diseases in clinic and experiment. Technology of serum express screening for presence of DNA abzymes is described. Comparative study of DNA-hydrolising activity in patients with different forms of systemic and organ-specific autoimmune diseases was performed. Blood of clinically healthy donors was usually free of IgG DNA-abzymes. DNA-abzymes were most often revealed in patients with systemic lupus erythematosus (SLE and rheumatoid arthritis (RA less often in patients with organ-specific forms of autoimmune disturbances. The results of the study confirm the hypothesis of autoimmune origin of IgG DNA abzymes and demonstrate the possibility to use them in clinical practice for monitoring to disease activity in SLE and RA.

    A vital task in the planning of peripheral bronchoscopy is the segmentation of the airway tree from a 3-D multidetector computed tomography chest scan. Unfortunately, existing methods typically do not sufficiently extract the necessary peripheral airways needed to plan a procedure. We present a robust method that draws upon both local and global information. The method begins with a conservative segmentation of the major airways. Follow-on stages then exhaustively search for additional candidate airway locations. Finally, a graph-based optimization method counterbalances both the benefit and cost of retaining candidate airway locations for the final segmentation. Results demonstrate that the proposed method typically extracts 2-3 more generations of airways than several other methods, and that the extracted airway trees enable image-guided bronchoscopy deeper into the human lung periphery than past studies.

    The diagnosis of peripheral pulmonary lesions (PPLs) is a challenging task for pulmonologists. Radial probe endobronchial ultrasound (R-EBUS) has been developed to enhance diagnostic yield. The objective of this study was to evaluate the effectiveness of R-EBUS in the diagnosis of PPLs. A retrospective study was conducted on 174 patients diagnosed with PPLs who underwent EBUS-guided bronchoscopy. Histological examination of specimens obtained by transbronchial lung biopsy (TBLB) and cytological examinations of brushing smear, brush rinse fluid and bronchoalveolar lavage fluid (BALF) were evaluated for the diagnosis. The mean diameter of the PPLs was 25.1 ± 10.7 mm. The final diagnoses included 129 malignancies and 45 benign lesions. The overall diagnostic yield of EBUS-guided bronchoscopy was 79.9%. Neither size nor etiology of the PPLs influenced the diagnostic performance of EBUS-guided bronchoscopy (82.9% vs. 74.6% for PPLs>20mm and PPLs≤20mm; p=0.19, and 82.9% vs. 71.1% for malignancy and benign diseases; p=0.09). TBLB rendered the highest yield among these specimens (69.0%, 50.6%, 42.0%, and 44.3% for TBLB, brushing smear, brush rinse fluid, and BALF, respectively; p<0.001). The combination of TBLB, brush smear, and BALF provided the greatest diagnostic yield, while brush rinse fluid did not add benefits to the outcomes. R-EBUS-guided bronchoscopy is a useful technique in the diagnosis of PPLs. To achieve the highest diagnostic performance, TBLB, brushing smear and bronchoalveolar lavage should be performed together.

    Full Text Available Background: Lung separation is the basis of thoracic anesthesia, which is performed by different instruments. Checking probable malpositioning of tracheal tube needs fiberoptic bronchoscopy. The aim of this study was to compare respirator suggested compliance with fiberoptic findings in detecting major tracheal tube malpositioning.Methods: A total of 256 patients undergoing thoracic surgery with double-lumen tracheal tube insertion in Imam Khomeini Hospital, Tehran, Iran, during 2010-11 were divided into three groups (n=86. We used left-sided double-lumen tube (DLT for left or right-sided surgeries (groups 1 and 2, and right-sided DLT for left-sided surgeries (group 3. The position of the tubes was evaluated and compared using bag compliance versus fiberoptic bronchoscopy.Results: The mean age of the study population was 44.7±13.4 (16-73 years, while 155 (59.9% were male. The sensitivity, specificity, positive and negative predictive values, and the accuracy of bag compliance test for left-sided DLT in supine position were 40% (95% CI: 20-60%, 99% (95% CI: 96-99%, 84% (95% CI: 54-94% 92% (95% CI: 88-95% and 92% (95% CI: 87-95%, respectively. The above-mentioned variables for lateral decubitus position respectively were 27%, 98%, 76%, 89%, and 88%. Malpositioning was more prevalent in right-sided DLTs (P=0.02.Conclusion: Based on the results of this study, and the high specificity, positive predictive value, and accuracy of bag compliance test, its use is encouraged as an alternative to fiberoptic bronchoscopy for checking DLT position, specially, in emergent surgeries or when fiberoptic bronchoscopy is unreachable due to lack of expertise or personnel.

    Flexible fiber optic bronchoscopy is a valuable intervention for evaluation and management of respiratory diseases in both infants, pediatric and adult patients. The aim of this study is to investigate the influence of the airway supporting maneuvers on glottis view during pediatric flexible fiberoptic bronchoscopy. In this randomized, controlled, crossover study; patients aged between 0 and 15 years who underwent flexible fiberoptic bronchoscopy procedure having American Society of Anesthesiologists I-II risk score were included. Patients having risk of difficult intubation, intubated or patients with tracheostomy, and patients with reduced neck mobility or having cautions for neck mobility were excluded from this study. After obtaining best glottic view at the neutral position, patients were positioned jaw trust with open mouth, jaw trust with teeth prottution, head tilt chin lift and triple airway maneuvers and best glottis scores were recorded. Total of 121 pediatric patients, 57 girls and 64 boys, were included in this study. Both jaw trust with open mouth and jaw trust with teeth prottution maneuvers improved the glottis view compared with neutral position (p0.05). Head tilt chin lift and triple airway maneuvers improved glottis view when compared with both jaw trust with open mouth and jaw trust with teeth prottution maneuvers and neutral position (p0.05). All airway supporting maneuvers improved glottic view during pediatric flexible fiberoptic bronchoscopy; however head tilt chin lift and triple airway maneuvers were found to be the most effective maneuvers.

    Dexmedetomidine has the favorable properties of sedation, sympatholysis, analgesia, and a low risk of apnea. These properties suggest that dexmedetomidine may be useful in procedural sedation. In view of this, we conducted a pilot trial to determine the feasibility of using dexmedetomidine as a sole agent for providing sedation during awake diagnostic flexible bronchoscopy. Patients presenting for awake diagnostic flexible bronchoscopy consented to participate in a trial of dexmedetomidine sedation for the procedure. In addition to local anesthetic topicalization of the airways, dexmedetomidine was infused at 0.5 μg/kg over 10 minutes followed by an infusion of 0.2 to 0.7 μg/kg/h titrating to a Ramsay Sedation Scale score of 3. Hemodynamic parameters (heart rate, blood pressure), oxygenation status (pulse oximetry), adverse events, use of rescue sedation, and patient and proceduralist satisfaction were recorded during the trial. Five of 9 recruited patients required rescue sedation to allow the procedure to proceed. Dexmedetomidine as a sole agent at an infusion of 0.5 μg/kg over 10 minutes followed by an infusion of 0.2 to 0.7 μg/kg/h is unable to provide adequate sedation for awake diagnostic flexible bronchoscopy without the need for rescue sedation in a large proportion of patients.

    In the event of a high degree of airway obstruction, endotracheal intubation can be impossible and even dangerous, because it can cause complete airway obstruction, especially in patients with high tracheal lesions. However, a smaller endotracheal tube under the guidance of a bronchoscope can be insinuated past obstructive tumor in most noncircumferential cases. Here we report a case of successful fiberoptic bronchoscopy-assisted endotracheal intubation in a patient undergoing surgical resection of a large, high tracheal tumor causing severe tracheal stenosis. A 42-year-old Chinese man presented with dyspnea, intermittent irritable cough, and sleep deprivation for one and a half years. X-rays and computed tomography scan of the chest revealed an irregular pedunculated soft tissue mass within the tracheal lumen. The mass occupied over 90% of the lumen and caused severe tracheal stenosis. Endotracheal intubation was done to perform tracheal tumor resection under general anesthesia. After several failed conventional endotracheal intubation attempts, fiberoptic bronchoscopy-assisted intubation was successful. The patient received mechanical ventilation and then underwent tumor resection and a permanent tracheostomy. This case provides evidence of the usefulness of the fiberoptic bronchoscopy-assisted intubation technique in management of an anticipated difficult airway and suggests that tracheal intubation can be performed directly in patients with a tracheal tumor who can sleep in the supine position, even if they have occasional sleep deprivation and severe tracheal obstruction as revealed by imaging techniques.

    Lung cancer is the leading cause of cancer-related deaths worldwide with an overall 5-year survival rate of 17% after diagnoses. Indeed many patients tend to have a very poor prognosis, due to being diagnosed at an advanced stage. Conversely patients who are diagnosed at an early stage have a 5-year survival >70%, indicating that early detection of lung cancer is crucial to improve survival. Although flexible bronchoscopy is a relatively non-invasive procedure for patients suspected of having lung cancer, only 29% of carcinoma in situ (CIS) and 69% of microinvasive tumors were detectable using white light bronchoscopy (WLB) alone. As a result, in the past two decades, new bronchoscopic techniques have been developed to increase the yield and diagnostic accuracy, such as autofluorescence bronchoscopy (AFB), narrow band imaging (NBI) and high magnification bronchovideoscopy (HMB). However, due to the low specificity and the limitation to detect only proximal bronchial tree, new probe-based technologies have been introduced: radial endobronchial ultrasound (R-EBUS), optical coherence tomography (OCT), confocal laser endomicroscopy (CLE) and laser Raman spectroscopy (LRS). To date, although tissue biopsy remains the gold standard for diagnosing malignant/premalignant airway disease and some techniques are still investigational, bronchoscopic technologies can be considered the safest and most accurate tools to evaluate both central and distal airway mucosa.

    2009-01-01

    Pharmacokinetics and pharmacodynamics data are often analysed by mixed-effects modelling techniques (also known as population analysis), which has become a standard tool in the pharmaceutical industries for drug development. The last 10 years has witnessed considerable interest in the application of experimental design theories to population pharmacokinetic and pharmacodynamic experiments. Design of population pharmacokinetic experiments involves selection and a careful balance of a number of design factors. Optimal design theory uses prior information about the model and parameter estimates to optimize a function of the Fisher information matrix to obtain the best combination of the design factors. This paper provides a review of the different approaches that have been described in the literature for optimal design of population pharmacokinetic and pharmacodynamic experiments. It describes options that are available and highlights some of the issues that could be of concern as regards practical application. It also discusses areas of application of optimal design theories in clinical pharmacology experiments. It is expected that as the awareness about the benefits of this approach increases, more people will embrace it and ultimately will lead to more efficient population pharmacokinetic and pharmacodynamic experiments and can also help to reduce both cost and time during drug development.

    The purpose of this study was to understand and describe the leadership experience of clinical nurses. During 2014, data were collected using focus group interviews. Three focus group interviews were held with a total of 20 clinical nurses participating. All interviews were recorded as they were spoken and transcribed and data were analyzed using qualitative content analysis. Fifteen categories emerged from the five main themes. 1) Thoughts on the leadership category: to lead others, to cope with problem situations adequately and to serve as a shield against difficulties. 2) Situations requiring leadership: situation that requires correct judgement, coping and situations that need coordination and cooperation. 3-1) Leadership behaviors: other-oriented approach and self-oriented approach. 3-2) Leadership behavior consequences: relevant compensation and unfair termination. 4-1) Facilitators of leadership: confidence and passion for nursing and external support and resources. 4-2) Barriers to leadership: non-supportive organization culture and deficiency in own leadership competencies. 5) Strategies of leadership development: strengthen leadership through self-development and organizational leadership development. In conclusion, the results indicate that it is necessary to enhance clinical nurses' leadership role in healthcare. Enhancement can be achieved through leadership programs focused on enlarging leadership experience, constant self-development, leadership training, and development of leadership competencies suited to the nursing environment.

    Peer learning is an educational process wherein someone of the same age or level of experience level interacts with other students interested in the same topic. There is limited evidence specifically focusing on the practical use of peer learning in Iran. The aim of this study was to explore nursing students' experiences of peer learning in clinical practice. A qualitative content analysis was conducted. Focus groups were used to find the students' experiences about peerlearning. Twenty-eight baccalaureate nursing students at Bushehr University of Medical Sciences were selected purposively, and were arranged in four groups of seven students each. The focus group interviews were conducted using a semi-structured interview schedule. All interviews were tape-recorded, transcribed verbatim, and analyzed using conventional content analysis method. The analysis identified four themes: Paradoxical dualism, peer exploitation, first learning efficacy, and socialization practice. Gained advantages and perceived disadvantages created paradoxical dualism, and peer exploitation resulted from peer selection and peer training. Nursing students reported general satisfaction concerning peer learning due to much more in-depth learning with little stress than conventional learning methods. Peer learning is a useful method for nursing students for practicing educational leadership and learning the clinical skills before they get a job.

    This paper compares the clinical experience in acute conditions of the undergraduate students of a medical school from a developing country (Malaysia) with those from a developed country (UK). This study was conducted at the School of Medical Sciences, Universiti Sains Malaysia (USM). Through questionnaire survey enquiry was made about 27 acute medical conditions (i.e. conditions related to internal medicine, paediatrics, and psychiatry), 15 acute surgical conditions (i.e. conditions related to general surgery, orthopaedics, ophthalmology, otorhinolaryngology, gynaecology and obstetrics), 15 surgical operations and 26 practical procedures. The results obtained were compared with published data from the UK. Acute medical conditions were seen by higher number of the USM students but with less frequency than the British students. The USM students saw practical procedures more frequently than the British students did, but almost an equal number performed these procedures independently. The British students attended surgical operations more frequently than the USM students did. Given the limitations of comparison (epidemiological, cultural and geographical differences, conventional curriculum (in the British medical schools) vs. problem based learning curriculum (in the Malaysian medical school)) the overall clinical experience of the medical students in the USM and the UK was comparable. The USM students had more opportunities to observe cases and procedures but "hands on" experience was similar to that of the British students.

    The complexity of health care requires excellent leadership to address the challenges of access, quality, and cost of care. Because competencies to lead differ from clinical or research skills, there is a compelling need to develop leaders and create a talent pipeline, perhaps especially in physician-led organizations like Cleveland Clinic. In this context, we previously reported on a cohort-based physician leadership development course called Leading in Health Care and, in the current report, detail an expanded health care leadership development programme called the Cleveland Clinic Academy (CCA). CCA consists of a broad suite of offerings, including cohort-based learning and 'a la carte' half- or full-day courses addressing specific competencies to manage and to lead. Academy attendance is optional and is available to all physicians, nurses, and administrators with the requisite experience. Course selection is guided by competency matrices which map leadership competencies to specific courses. As of December 2012, a total of 285 course sessions have been offered to 6,050 attendees with uniformly high ratings of course quality and impact. During the past 10 years, Cleveland Clinic's leadership and management curriculum has successfully created a pipeline of health care leaders to fill executive positions, search committees, board openings, and various other organizational leadership positions. Health care leadership can be taught and learned.

    A clinical experience of using thalidomide in type-2 lepra reaction (ENL) in 90 male patients--57 with lepromatous leprosy (LL) and 33 with borderline lepromatous leprosy (BL)--is described. All the patients responded well although some took a longer time to improve. No major side effects were observed except for giddiness in 10 and gastrointestinal upsets in 7 patients. Thalidomide thus appears to be a very effective drug in the treatment of severe type-2 lepra reaction and apart from its historically well-documented embryopathic effects, does not seem to have any other serious side effects in the patients under study.

    The supernatural fears associated with the experience of isolated sleep paralysis in the culture of developing countries is sometimes associated with the evolution of somatic symptoms of psychological origin in patients predisposed to neurotic illness. Patients rarely spontaneously volunteer these fears and doctors pay them scant attention. Illustrative case histories that demonstrate the dynamics of the clinical presentation, as well as the treatment approach, are highlighted. It is hoped that doctors in general medical practice and in psychological medicine in developing countries where belief in supernatural causation of illness is rife will consider these factors in order to provide more effective treatment.

    To improve clinical study developments for elderly populations, we aim to understand how they transfer their experiences into validated, standardised self-completed study measurement instruments. We analysed how women (mean 78±8 years of age) participating in a randomised controlled trial (RCT) cognised study instruments used to evaluate outcomes of the intervention. The interview study was nested in an RCT on chronic neck pain using common measurement instruments situated in an elderly community in Berlin, Germany, which comprised of units for independent and assisted-living options. The sample (n=20 women) was selected from the RCT sample (n=117, 95% women, mean age 76 (SD±8) years). Interview participants were selected using a purposive sampling list based on the RCT outcomes. We asked participants about their experiences completing the RCT questionnaires. Interviews were analysed thematically, then compared with the questionnaires. Interviewees had difficulties in translating complex experiences into a single value on a scale and understanding the relationship of the questionnaires to study aims. Interviewees considered important for the trial that their actual experiences were understood by trial organisers. This information was not transferrable by means of the questionnaires. To rectify these difficulties, interviewees used strategies such as adding notes, adding response categories or skipping an item. Elderly interview participants understood the importance of completing questionnaires for trial success.

    Objectives To improve clinical study developments for elderly populations, we aim to understand how they transfer their experiences into validated, standardised self-completed study measurement instruments. We analysed how women (mean 78±8 years of age) participating in a randomised controlled trial (RCT) cognised study instruments used to evaluate outcomes of the intervention. Setting The interview study was nested in an RCT on chronic neck pain using common measurement instruments situated in an elderly community in Berlin, Germany, which comprised of units for independent and assisted-living options. Participants The sample (n=20 women) was selected from the RCT sample (n=117, 95% women, mean age 76 (SD±8) years). Interview participants were selected using a purposive sampling list based on the RCT outcomes. Outcomes We asked participants about their experiences completing the RCT questionnaires. Interviews were analysed thematically, then compared with the questionnaires. Results Interviewees had difficulties in translating complex experiences into a single value on a scale and understanding the relationship of the questionnaires to study aims. Interviewees considered important for the trial that their actual experiences were understood by trial organisers. This information was not transferrable by means of the questionnaires. To rectify these difficulties, interviewees used strategies such as adding notes, adding response categories or skipping an item. Conclusions Elderly interview participants understood the importance of completing questionnaires for trial success. This led to strategies of completing the questionnaires that resulted in ‘missing’ or ambiguous data. To improve data collection in elderly populations, educational materials addressing the differential logics should be developed and tested. Pilot testing validated instruments using cognitive interviews may be particularly important in such populations. Finally, when the target of an

    Improving medication management is an important component of comprehensive care coordination for health systems. The Managing Your Medication for Education and Daily Support (MyMeds) medication management program at the University of California Los Angeles addresses medication management issues by embedding trained clinical pharmacists in primary care practice teams. The aim of this work was to examine and explore physician opinions about the clinical pharmacist program and identify common themes among physician experiences as well as barriers to integration of clinical pharmacists into primary care practice teams. We conducted a mixed quantitative-qualitative methods study consisting of a cross-sectional physician survey (n = 69) as well as semistructured one-on-one physician interviews (n = 13). Descriptive statistics were used to summarize survey responses, and standard qualitative content-analysis methods were used to identify major themes from the interviews. The survey response rate was 61%; 13 interviews were conducted. Ninety percent of survey respondents agreed or strongly agreed that having the pharmacist in the office makes management of the patient's medication more efficient, 93% agreed or strongly agreed that pharmacist recommendations are clinically helpful, 71% agreed or strongly agreed that having access to a pharmacist has increased their knowledge about medications they prescribe, and 75% agreed or strongly agreed that having a pharmacist as part of the primary care team has made their job easier. Qualitative interviews corroborated survey findings, and physicians highlighted the value of the clinical pharmacist's communication, team care and expanded roles, and medication management. Primary care physicians valued the integrated pharmacy program highly, particularly its features of strong communication, expanded roles, and medication management. Pharmacists were viewed as integral members of the health care team. Copyright © 2017 American

    This study aimed to investigate the clinical effectiveness of dexmedetomidine and midazolam for sedation of intensive care unit (ICU) patients requiring flexible fiberoptic bronchoscopy (FFB).This retrospective cohort study included 148 patients from the third ICU ward of the Second Affiliated Hospital of Harbin Medical University (Harbin, China) who received simultaneous invasive mechanical ventilation and FFB between March 2012 and December 2014. Patients were divided into dexmedetomidine (n  =  72) and midazolam (n  =  76) groups according to sedative mode. The sedative effects, incidence of adverse events, and bronchoscopist satisfaction scores were compared between groups.During FFB, total sedation time and total time of FFB were significantly shorter in the midazolam group (P midazolam group (P  =  .007, .014 and .008, respectively). However, the incidence of other adverse events was not significantly different between groups. In addition, bronchoscopist satisfaction scores were significantly higher in the midazolam compared with dexmedetomidine group (7.72 ± 1.65 vs 7.08 ± 1.77; P  =  .030).For sedation of ICU patients during FFB, combination of midazolam and dexmedetomidine demonstrated an enhanced sedative effect, lower incidence of adverse events, and higher bronchoscopist satisfaction score compared with dexmedetomidine alone, thus represents a suitable alternative sedative for FFB patients.

    Trichomycosis is asymptomatic bacterial infection of the axillary hairs caused by Corynebacterium sp. to bring a series of cases of trichomycosis, its clinical and microbiological experience. This report consists in a linear and observational retrospective study of 15 years of cases of trichomycosis confirmed clinically and microbiologically. Fifty six confirmed cases of trichomycosis were included in this report. The majority were men 53/56 (94.6%), mean age was 32.5 years. The most commonly affected area was the axilla (92%), trichomycosis flava was the principal variant 55/56 (98.2%) and signs and symptoms associated were hyperhidrosis (87.5%), hairs' texture change (57.1%) and odor (35.7%). Bacterial concretions were observed in all cases, and the predominant causative agent in 89.3% of all cases was Corynebacterium sp. Thirty patients were included in therapeutic portion of the study, and 28 (93.3%) of them experienced a clinical and microbiological cure. Trichomycosis is asymptomatic, superficial infection, which primarily affects axillary hairs.

    The purpose of the postmortem examination is to offer answers to explain the cause and manner of death. In the case of perinatal, infant and paediatric postmortem examinations, the goal is to identify unsuspected associated features, to describe pathogenic mechanisms and new conditions, and to evaluate the clinical management and diagnosis. Additionally, the postmortem examination is useful to counsel families regarding the probability of recurrence in future pregnancies and to inform family planning. Worldwide the rate of paediatric autopsy examinations has significantly declined during the last few decades. Religious objections to postmortem dissection and organ retention scandals in the United Kingdom provided some of the impetus for a search for non-invasive alternatives to the traditional autopsy; however, until recently, imaging studies remained an adjunct to, rather than a replacement for, the traditional autopsy. In 2012, Sheffield Children's Hospital National Health Service Foundation Trust set up the service provision of minimally invasive fetal, perinatal and neonatal autopsy, while a postmortem imaging service has been running in Melbourne, Australia, since 2008. Here we summarise the essentials of a business case and practical British and Australian experiences in terms of the pathological and radiologic aspects of setting up a minimally invasive clinical service in the United Kingdom and of developing a clinical postmortem imaging service as a complementary tool to the traditional autopsy in Australia.

    To investigate the effectiveness, related knowledge, attitudes, and practices of hand hygiene (HH) among dental students with different levels of clinical experience. This was a cross-sectional analytical study. Bacterial samples on the participants' hands were obtained using a swab technique before and after handwashing, for oral surgical procedures. After culturing, the colony-forming units were counted. Self-reported questionnaires reflecting the knowledge, attitudes, and practices related to HH were completed by the participants. This study was performed in a primary oral health care institution, Faculty of Dentistry, Chulalongkorn University (Bangkok, Thailand). Bacterial samples and self-reported questionnaires were collected in the Department of Oral and Maxillofacial Surgery. Bacterial culture was performed in the Department of Microbiology. The 120 participants comprised first, second, third-year clinical training students (CTs), and postgraduate dental students (PGs) (32, 34, 30, and 24 participants, respectively). More than 99% of the bacteria were eliminated from the participants' hands after handwashing. Significantly higher numbers of bacteria were recovered from the hands of the PGs compared with those of the CTs, and the hands of the third-year CTs compared with those of the first-year CTs (p < 0.001), after HH. The first-year CTs had the highest attitude scores, whereas the PGs had the lowest practice scores. The knowledge scores were similar in all groups. HH effectiveness, attitudes, and practices of dental students decreased as students gained more clinical experience, whereas knowledge did not. Our results suggest that HH instruction should be given throughout the duration of dental students' education. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc.

    Full Text Available Abstract Background There has been an increased interest in recruiting health professionals with a clinical background to management positions in health care. We know little about the factors that influence individuals’ decisions to engage in management. The aim of this study is to explore clinicians’ journeys towards management positions in hospitals, in order to identify potential drivers and barriers to management recruitment and development. Methods We did a qualitative study which included in-depth interviews with 30 clinicians in middle and first-line management positions in Norwegian hospitals. In addition, participant observation was conducted with 20 of the participants. The informants were recruited from medical and surgical departments, and most had professional backgrounds as medical doctors or nurses. Interviews were analyzed by systemic text condensation. Results We found that there were three phases in clinicians’ journey into management; the development of leadership awareness, taking on the manager role and the experience of entering management. Participants’ experiences suggest that there are different journeys into management, in which both external and internal pressure emerged as a recurrent theme. They had not anticipated a career in clinical management, and experienced that they had been persuaded to take the position. Being thrown into the position, without being sufficiently prepared for the task, was a common experience among participants. Being left to themselves, they had to learn management “on the fly”. Some were frustrated in their role due to increasing administrative workloads, without being able to delegate work effectively. Conclusions Path dependency and social pressure seems to influence clinicians’ decisions to enter into management positions. Hospital organizations should formalize pathways into management, in order to identify, attract, and retain the most qualified talents. Top managers

  10. Concept-Based Learning in Clinical Experiences: Bringing Theory to Clinical Education for Deep Learning.

    2016-07-01

    Concept-based learning is used increasingly in nursing education to support the organization, transfer, and retention of knowledge. Concept-based learning activities (CBLAs) have been used in clinical education to explore key aspects of the patient situation and principles of nursing care, without responsibility for total patient care. The nature of best practices in teaching and the resultant learning are not well understood. The purpose of this multiple-case study research was to explore and describe concept-based learning in the context of clinical education in inpatient settings. Four clinical groups (each a case) were observed while they used CBLAs in the clinical setting. Major findings include that concept-based learning fosters deep learning, connection of theory with practice, and clinical judgment. Strategies used to support learning, major teaching-learning foci, and preconditions for concept-based teaching and learning will be described. Concept-based learning is promising to support integration of theory with practice and clinical judgment through application experiences with patients. [J Nurs Educ. 2016;55(7):365-371.].

    Students are rarely taught communication skills in the context of clinical reasoning training. The purpose of this project was to combine the teaching of communication skills using SPs with clinical reasoning exercises in a Group Objective Structured Clinical Experience (GOSCE) to study feasibility of the approach, the effect on learners' self-efficacy and attitude toward learning communication skills, and the effect of providing multiple sources of immediate, collaborative feedback. GOSCE sessions were piloted in Pediatrics and Medicine clerkships with students assessing their own performance and receiving formative feedback on communication skills from peers, standardized patients (SPs), and faculty. The sessions were evaluated using a retrospective pre/post-training questionnaire rating changes in self-efficacy and attitudes, and the value of the feedback. Results indicate a positive impact on attitudes toward learning communication skills and self-efficacy regarding communication in the clinical setting. Also, learners considered feedback by peers, SPs, and faculty valuable in each GOSCE. The GOSCE is an efficient and learner-centered method to attend to multiple goals of teaching communication skills, clinical reasoning, self-assessment, and giving feedback in a formative setting. The GOSCE is a low-resource, feasible strategy for experiential learning in communication skills and clinical reasoning. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Computing has become an integral part of many disciplines nowadays, turning it into an evermore necessary working tool. Internet provides a fast and easy way to collect scientific data and is becoming a more and more effective and safe way to transmit data. It is also an efficient means for interaction and information sharing within a work group that provides the necessary flexibility. A pilot project was conducted replacing the traditional hardcopy version of the case report form for an electronic one (e-CRF) and with access to Internet within the Naturalistic Randomized Clinical Trial of the Effectiveness of Olanzapine and Risperidone in the Treatment of Schizophrenia. Carrying out this pilot project has given us the opportunity to determine the advantages electronic data collection (EDC) by Internet has to offer both researchers and sponsors. The results have optimized time management, since it is easier to work in real time; data quality is improved, since intermediates are eliminated, and it facilitates communication amongst the different parties involved in the project. The use of this technology requires updated Internet connections and adequate personal computers, since the possibilities offered by the computer system and high-speed connection are critical in conducting the project. Obviously, this may involve a higher initial investment, but the results have revealed to us that these start-up costs are later offset by lowering personnel costs or by decreasing the number of monitoring visits. On the basis of our experience and that of the participating investigators, certain recommendations for future clinical trials using e-CRF can be made. We will go into these recommendations in greater depth throughout this paper. In short, EDC can dramatically improve the clinical trial process, opening the door to new technologies in the world of clinical research, not only for sponsors, but also for clinicians.

    Persistent or recurrent wheezing is a common indication for flexible bronchoscopy, as anatomic and infectious or inflammatory changes are highly prevalent. We sought to evaluate the prevalence of anatomic, infectious, and inflammatory disease in a cohort of children undergoing flexible bronchoscopy for wheezing or poorly controlled asthma. We retrospectively reviewed all children flexible bronchoscopy at our center from October 29, 2012-December 31, 2016 for the primary or secondary indication of wheezing (persistent, frequently recurring, or atypical) or poorly controlled asthma. A total of 101 procedures were identified in 94 patients, aged 3 months to 18 years. Potential anatomic causes for wheezing identified in 45.7% of patients and inflammatory changes in 49.5% of procedures. This included the identification of a laryngeal cleft in 17% for which half required medical or surgical management. Tracheobronchomalacia was the most commonly identified anatomic lesion. Thirty children from this cohort had poorly controlled asthma. Among this subgroup, 54% had increased neutrophils on BAL and 30% had an anatomic contributor to wheezing, including one with a laryngeal cleft. Based on findings from flexible bronchoscopy, management changes made in 63.8% of patients. This included medication changes in 54 and surgical intervention in 9. We conclude that transnasal flexible bronchoscopy has high yield in children with recurrent, persistent, or atypical wheezing and those with poorly controlled asthma. Laryngeal cleft has a reasonably high prevalence that warrants specific evaluation in this population. © 2017 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Climate change is a global public health problem that will require complex thinking if meaningful and effective solutions are to be achieved. In this conceptual paper we argue that GPs have much to bring to the issue of climate change from their wide-ranging clinical experience and from the principles underpinning their clinical methods. This experience and thinking calls forth particular contributions GPs can and should make to debate and action. Discussion We contend that the privileged experience and GP way of thinking can make valuable contributions when applied to climate change solutions. These include a lifetime of experience, reflection and epistemological application to first doing no harm, managing uncertainty, the ability to make necessary decisions while possessing incomplete information, an appreciation of complex adaptive systems, maintenance of homeostasis, vigilance for unintended consequences, and an appreciation of the importance of transdisciplinarity and interprofessionalism. Summary General practitioners have a long history of public health advocacy and in the case of climate change may bring a way of approaching complex human problems that could be applied to the dilemmas of climate change.

    1995-01-01

    In Norway, organizational changes in hospitals and a stronger focus on patient safety have changed the way of organizing and managing paper based patient records. Hospital-wide patient records tend to replace department based records. Since not only clinicians, but also other non-medical staff have access to the paper records, they also have easy access to all the information which is available on a specific patient; such a system has obvious 'side effects' on privacy and security. Computer based patient records (CPRs) can provide the solution to this apparent paradox if the complex aspects of security, privacy, effectiveness, and user friendliness are focused on jointly from the outset in designing such systems. Clinical experiences in Norway show that it is possible to design patient record systems that provide a very useful tool for clinicians and other health care personnel (HCP) while fully complying with comprehensive security and privacy requirements.

    Full Text Available Topical airway anesthesia is known to improve tolerance and patient satisfaction during flexible bronchoscopy (FB. Lidocaine is commonly used, delivered as an atomized spray. The current study assesses safety and patient satisfaction for nasal anesthesia of a new atomization device during outpatient bronchoscopy in lung transplant recipients.Using a prospective, non-blinded, cross-over design, patients enrolled between 01-10-2014 and 24-11-2014 received 2% lidocaine using the standard reusable nasal atomizer (CRNA. Those enrolled between 25-11-2014 and 30-01-2015, received a disposable intranasal mucosal atomization device (DIMAD. After each procedure, the treating physician, their assistant and the patient independently rated side-effects and satisfaction, basing their responses on visual analogue scales (VAS. At their next scheduled bronchoscopy during the study period, patients then received the alternative atomizer. Written consent was obtained prior to the first bronchoscopy, and the study approved by the institutional ethics committee.Of the 252 patients enrolled between 01-10-2014 and 30-01-2015, 80 (32% received both atomizers. Physicians reported better efficacy (p = 0.001 and fewer side effects (p< = 0.001 for DIMAD in patients exposed to both procedures. Among patients with one visit, physicians and their assistants reported improved efficacy (p = 0.018, p = 0.002 and fewer side effects (p< = 0.001, p = 0.029 for the disposable atomizer, whereas patients reported no difference in efficacy or side effects (p = 0.72 and p = 0.20. No severe adverse events were noted. The cost of the reusable device was 4.08€ per procedure, compared to 3.70€ for the disposable device.Topical nasal anesthesia via a disposable intranasal mucosal atomization device (DIMAD offers comparable safety and patient comfort, compared to conventional reusable nasal atomizers (CRNA in lung transplant recipients. Procedural costs were reduced by 0.34€ per

    Tracheobronchopathia osteochondroplastica (TO) is a rare benign disorder affecting the trachea and occasionally the bronchi. We report a case of TO presenting as a respiratory insufficiency. Chest radiograh revealed an irregular narrowing of the intra thoracic trachea and a parenchymal consolidation of the left lower lobe. Magnetic resonance examination of the chest showed a diffuse irregular thickening of the trachea and central bronchi, which had an intermediate signal intensity with punctiform low signal intensity suggesting calcifications and no contrast enhancement. The diagnosis was confirmed by bronchoscopy and biopsies.

    The surgical treatment for giant neurofibromatosis-1 (NF-1) requires comprehensive measures. Presently, there is no systematic description of surgical treatment. Because of its high level of risk, we want to share our clinical experience. From 2011 to 2014, patients (n = 8, 5 female and 3 male patients, aging from 31 to 45 years-old) were included in the study. The tumours were located on the trunk (n = 5) or face (n = 3). In addition to routine examination, blood storage was also prepared. Preoperative consultation from related departments was critical at first. Related artery embolisation was also carried out. In the operation, we checked thromboelastography, based on which reasonable blood component transfusion was implemented. Autologous blood transfusion was also ready. An instrument of copper needle or ring ligation was used to reduce haemorrhage before the surgery. Protruding or drooping portions of the tumours were excised. A pressurised bandage was applied when the surgery was completed. After the surgery, besides the routine monitoring of vital signs, re-haemorrhage should be detected in time. Then, we should decide whether blood transfusion or surgery was required again. Expanders were implanted in one female patient with facial injuries before removing the tumour. Then, expanded flaps were applied to repair the secondary wound. According to the above clinical route, after an average of 1-year follow-up, no patients died, and other unforeseen events did not occur. Wounds healed well in all patients. The tumor was excised as much as possible. No facial nerve paralysis occurred in the facial sites. Expanded flaps necrosis WAS not encountered. It is essential to design the educational clinical route for treating NF-1 when a giant protruding tumour is advised to be excised, which can minimise the risk of surgery and assure us of the maximum range of resection. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

  5. Traumatic effects of political repression in Chile: a clinical experience.

    Cordal, Margarita Díaz

    2005-10-01

    The author examines psychic trauma resulting from human rights violations in Chile. Starting from trauma theories developed by authors such as Ferenczi, Winnicott and Stolorow, she posits the relevance of the subject's emotionally significant environment in the production of the traumatic experience. She describes the characteristics of the therapeutic process on the basis of a clinical case. She emphasizes the need to recognize the damage that may be produced within the reliable link between patient and analyst, pointing out the risk of retraumatization if analysts distance themselves and apply 'technique' rigorously, leaving out their own subjective assessments. Therapists must maintain their focus on the conjunction of the patient's intersubjective context and inner psychic world both when exploring the origin of the trauma and when insight is produced. The author posits repetition in the transference as an attempt at reparation, at finding the expected response from the analyst that will help patients assemble the fragments of their history and achieve, as Winnicott would put it, a feeling of continuity in the experience of being.

    We proposed a new virtual bronchoscopy tool to improve the accuracy of traditional transbronchial needle aspiration for mediastinal staging. Chest-computed tomographic images (1 mm thickness) were reconstructed with Osirix software to produce a virtual bronchoscopic simulation. The target adenopathy was identified by measuring its distance from the carina on multiplanar reconstruction images. The static images were uploaded in iMovie Software, which produced a virtual bronchoscopic movie from the images; the movie was then transferred to a tablet computer to provide real-time guidance during a biopsy. To test the validity of our tool, we divided all consecutive patients undergoing transbronchial needle aspiration retrospectively in two groups based on whether the biopsy was guided by virtual bronchoscopy (virtual bronchoscopy group) or not (traditional group). The intergroup diagnostic yields were statistically compared. Our analysis included 53 patients in the traditional and 53 in the virtual bronchoscopy group. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy for the traditional group were 66.6%, 100%, 100%, 10.53% and 67.92%, respectively, and for the virtual bronchoscopy group were 84.31%, 100%, 100%, 20% and 84.91%, respectively. The sensitivity ( P  = 0.011) and diagnostic accuracy ( P  = 0.011) of sampling the paratracheal station were better for the virtual bronchoscopy group than for the traditional group; no significant differences were found for the subcarinal lymph node. Our tool is simple, economic and available in all centres. It guided in real time the needle insertion, thereby improving the accuracy of traditional transbronchial needle aspiration, especially when target lesions are located in a difficult site like the paratracheal station.

    false-positive findings. The side-by-side feature analysis showed higher conspicuity scores for tomosynthesis compared to conventional 2D for cancers presenting as spiculated masses and distortions. Conclusion: Tomosynthesis is a promising new technique. Our preliminary clinical experience shows that there is a potential for increasing the sensitivity using this new technique, especially for cancers manifesting as spiculated masses and distortions.

    2015-03-01

    Aggressive recruitment strategies used in Canadian undergraduate nursing programs have enjoyed only moderate success, given that male students represent a small percentage of the student population. To determine whether there were gender differences in their sense of belonging, undergraduate nursing students (n = 462) in southern Alberta were surveyed using the Belongingness Scale-Clinical Placement Experience questionnaire. No significant gender differences were found on two of the subscales. However, male students demonstrated significantly lower scores on the efficacy subscale (p = 0.02). This finding suggests that some men experience feelings of marginalization and discrimination. Nurse educators and students are encouraged to explore their worldviews related to gendered performances and teaching practices that create bias. Practice environments are encouraged to deinstitutionalize policies and procedures that accentuate femininities of care. Finally, men entering into the nursing profession are encouraged to reflect on how their gender performance may facilitate or detract from their feelings of belonging.

    Full Text Available Background and objective The aim of this study is to determine the best reference values of the optimal evaluation indexes that identify different disease types. Disease identification was conducted using the YUV quantitative analysis of autofluorescence bronchoscopy (AFB images in the target areas. Furthermore, this study discusses the significance of AFB in the diagnosis of the central-type lung cancer. Methods A biopsy was conducted for cases that showed pathologic changes under either autofluorescence or white-light bronchoscopy. Moreover, MATLAB was used to carry out the quantitative analyses of lesion in multi-color spaces from AFB images. The cases were divided into different groups according to the pathological diagnosis of normal bronchial mucosa, inflammation, low-grade dysplasia (LGD, high-grade dysplasia (HGD, and invasive cancer. SPSS 11.5 was used to process the data for statistical analysis. Results The Y values were different and statistically different between invasive cancer and LGD (P<0.001 and invasive cancer and inflammation (P=0.040, respectively. The U values between invasive cancer and the other groups were statistically different (P<0.050. Similarly, the V values between invasive cancer and LGD and inflammation and normal bronchial mucosa were different. Lastly, the V values between normal bronchial mucosa and HGD and inflammation and normal bronchial mucosa were different. Conclusion The YUV values in the AFB effectively identified benign and malignant diseases and were proven to be effective scientific bases for the accurate AFB diagnosis of lung cancer.

    Full Text Available Background. The early diagnosis of malignant and premalignant changes of the bronchial mucosa remains a major challenge during bronchoscopy. Intravital staining techniques are not new. Previous small case series suggested that analysis of the bronchial mucosal surface using chromoendoscopy allows a prediction between neoplastic and nonneoplastic lesions. Objectives. The aim of the present study was to evaluate chromobronchoscopy as a method to identify malignant and premalignant lesions in the central airways in a prospective manner. Methods. In 26 patients we performed chromoendoscopy with 0.1% methylene blue during ongoing flexible white light bronchoscopy. Circumscribed lesions in central airways were further analyzed by biopsies and histopathologic examination. Results. In the majority of cases neither flat nor polypoid lesions in the central airways were stained by methylene blue. In particular, exophytic growth of lung cancer did not show any specific pattern in chromobronchoscopy. However, a specific dye staining was detected in one case where exophytic growth of metastatic colorectal cancer was present in the right upper lobe. In two other cases, a circumscribed staining was noted in unsuspicious mucosa. But histology revealed inflammation only. Conclusions. In contrast to previous studies, the present findings clearly indicate that chromobronchoscopy is not useful for early detection of malignant or premalignant lesions of the central airways.

    The choice of sampling techniques in bronchoscopy with sampling from a visible lesion will depend on the expected diagnostic yields and the costs of the sampling techniques. The aim of this study was to determine the most economical combination of sampling techniques when approaching endobronchial visible lesions. A cost minimization analysis was performed. All bronchoscopies from 2003 and 2004 at Haukeland university hospital, Bergen, Norway, were reviewed retrospectively for diagnostic yields. 162 patients with endobronchial disease were included. Potential sampling techniques used were biopsy, brushing, endobronchial needle aspiration (EBNA) and washings. Costs were estimated based on registration of equipment costs and personnel costs. Sensitivity analyses were performed to determine threshold values. The combination of biopsy, brushing and EBNA was the most economical strategy with an average cost of Euro 893 (95% CI: 657, 1336). The cost of brushing had to be below Euro 83 and it had to increase the diagnostic yield more than 2.2%, for biopsy and brushing to be more economical than biopsy alone. The combination of biopsy, brushing and EBNA was more economical than biopsy and brushing when the cost of EBNA was below Euro 205 and the increase in diagnostic yield was above 5.2%. In the current study setting, biopsy, brushing and EBNA was the most economical combination of sampling techniques for endobronchial visible lesions.

    State-of-the-art image-guided intervention (IGI) systems for lung-cancer management draw upon high-resolution three-dimensional multi-detector computed-tomography (MDCT) images and bronchoscopic video. An MDCT scan provides a high-resolution three-dimensional (3D) image of the chest that is used for preoperative procedure planning, while bronchoscopy gives live intraoperative video of the endobronchial airway tree structure. However, because neither source provides live extraluminal information on suspect nodules or lymph nodes, endobronchial ultrasound (EBUS) is often introduced during a procedure. Unfortunately, existing IGI systems provide no direct synergistic linkage between the MDCT/video data and EBUS data. Hence, EBUS proves difficult to use and can lead to inaccurate interpretations. To address this drawback, we present a prototype of a multimodal IGI system that brings together the various image sources. The system enables 3D reconstruction and visualization of structures depicted in the 2D EBUS video stream. It also provides a set of graphical tools that link the EBUS data directly to the 3D MDCT and bronchoscopic video. Results using phantom and human data indicate that the new system could potentially enable smooth natural incorporation of EBUS into the system-level work flow of bronchoscopy.

    According to current guidelines flexible bronchoscopy is usually performed under sedation. Previously it has been demonstrated that combined sedation with e. g. the combination of midazolam and propofol or an opioid might have several advantages over sedation with just one sedative drug. However, little is known about the efficacy and safety of combined sedation with midazolam, fentanyl and propofol (MFP) compared to sedation with midazolam and fentanyl (MF) or midazolam and propofol (MP). We carried out a retrospective analysis of bronchoscopies performed under triple (MFP) or double sedation (MF and MP) in an academic hospital. 1392 procedures were analyzed (MFP: n = 824; MF: n = 272; MP: n = 296). In particular, we compared the occurrence of complications and the dosage of administered sedative drugs between the groups. The occurrence of adverse events (MFP vs. MF: odds ratio (OR) 1.116 [95% CI 0.7741 to 1.604]; MFP vs. MP: OR 0.8296 [95% CI 0.5939 to 1.16] and severe adverse events (MFP vs. MF: OR 1.581 [95% CI 0.5594 to 4.336]; MFP vs. MP: OR 3.47 [95% CI 0.908 to 15.15]; all p>0.05) was similar in all groups. The dosage of midazolam was lower in the MFP compared to the MF or MP group (MFP vs. MF: Cohen's d 0.075; MFP vs. MP: Cohen's d 0.225; all pmidazolam and propofol.

    Full Text Available Introduction: Craving is recognized as a formidable barrier in the management of patients with alcohol dependence. Among pharmacological agents that have been used in experimental studies for reduction in craving, baclofen appears to have a significant advantage over other agents. Methodology: The study is retrospective chart review of patients (n = 113 who have been treated with baclofen for alcohol dependence in a tertiary hospital of North India. Baseline assessments included sociodemography, motivation, quantity-frequency of alcohol use, and other alcohol-related clinical parameters. Weekly assessments, for a period of 4 weeks, were extracted from records which included dose of baclofen, craving intensity, and alcohol consumption. Results: The study sample was predominantly male, mean age of 41.49 (±9.75 years, most having a family history of substance use (70.97%, and many reporting binge use pattern in last year (49.46%. Baseline assessment revealed 48.7% of the sample was in precontemplation phase for alcohol use and 70% reported severe and persistent craving. This persistent craving was reported by only 15% of the sample by the end of 4 weeks treatment with baclofen (20–40 mg/day. Thirty-four percent of patients reported continued problematic use of alcohol by the end of 4 weeks. Conclusion: Our clinical experience suggests that baclofen reduces craving and alcohol consumption including in those with poor motivation. The drug causes few side effects and does not add to the intoxication effect of alcohol. Considering that baclofen is safe in those with liver cirrhosis and reduces withdrawal symptoms due to alcohol, a controlled trial comparing it with standard treatment is required.

    Full Text Available Diagnostic laboratory services in Alberta have been dramatically restructured over the past five years. In 1994, Alberta Health embarked on an aggressive laboratory restructuring that cut back approximately 30% of the overall monies previously paid to the laboratory service sector in Calgary. A unique service delivery model consolidated all institutional and community-based diagnostic testing in a company called Calgary Laboratory Services (CLS in late 1996. CLS was formed by a public/private partnership between the Calgary Regional Health Care Authority (CRHA and MDS-Kasper Laboratories. By virtue of its customer service base and scope of testing, CLS provides comprehensive regional laboratory services to the entire populace. Regional microbiology services within CLS have been successfully consolidated over the past three years into a centralized high volume laboratory (HVL. Because the HVL is not located in a hospital, rapid response laboratories (RRLs are operated at each acute care site. Although the initial principle behind the proposed test menus for the RRLs was that only procedures requiring a clinical turnaround time of more than 2 h stay on-site, many other principles had to be used to develop and implement an efficient and clinically relevant RRL model for microbiology. From these guiding principles, a detailed assessment of the needs of each institution and extensive networking with user groups, the functions of the microbiology RRLs were established and a detailed implementation plan drawn up. The experience at CLS with regards to restructuring a regional microbiology service is described herein. A post-hoc analysis provides the pros and cons of directing and operating a regionalized microbiology service.

    To evaluate the early clinical experience associated with radiofrequency (RF) ablation in patients with renal cell carcinoma (RCC). The RF ablation treatment was performed on 17 tumors from 16 patients (mean age, 60.5 years; range, 43 73 years) with RCC. The treatment indications were localized, solid renal mass, comorbidities, high operation risk, and refusal to perform surgery. All tumors were treated by a percutaneous CT (n = 10), followed by an US-guided (n = 2), laparoscopy-assisted US (n = 2), and an open (n = 2) RF ablation. Furthermore, patients underwent a follow- up CT at one day, one week, one month, three and six months, and then every six months from the onset of treatment. We evaluated the technical success, technical effectiveness, ablation zone, benign periablation enhancement, irregular peripheral enhancement, and complications. All 17 exophytic tumors (mean size, 2.2 cm; range, 1.1 5.0 cm) were completely ablated. Technical success and effectiveness was achieved in all cases and the mean follow-up period was 23.8 months (range, 17 33 months). A local recurrence was not detected in any of the cases; however, five patients developed complications as a result of treatment, including hematuria (n = 2), mild thermal injury of the psoas muscle (n = 1), mild hydronephrosis (n = 1), and fistula formation (n = 1). The RF ablation is an alternative treatment for exophytic RCCs and represents a promising treatment for some patients with small RCCs.

    Objective: Many studies have been conducted to investigate the efficacy of harmonic scalpels in thyroidectomies. Here, we present our clinical experiences with the instrument. Materials and Methods: The study was conducted at the General Surgery Department of the Ataturk University School of Medicine between January 2005 and July 2008. It was a prospective, randomized, controlled study. Patients with benign nodular goiter (BNG) were included in the study and randomly divided into three groups. The first group consisted of 47 patients, the second group consisted of 57 patients, and the third group consisted of 41 patients. Patients in the first group underwent the classical thyroidectomy. Those in the second group had only the superior thyroid arteries and veins ligated (with silk or polyglactin), while the other vascular structures were divided using a harmonic scalpel. In the third group, all arteries and veins of the thyroid gland were divided using a harmonic scalpel. In each group, mean operation time, amount of bleeding, amount of postoperative drainage, and other postoperative complications were recorded. Results: Operation time was significantly lower for patients in the third group. The degree of bleeding and postoperative drainage was lower in the second and third groups with respect to the first group. There was no significant difference among the groups in terms of the development of transient hypocalcemia or voice impairment. Conclusion: We conclude that the use of harmonic scalpels for a thyroidectomy is safe, shortens operative time, and decreases intraoperative bleeding. PMID:25610032

    2003-04-01

    Background: Standard treatment in patients with malignant glioma consists of surgery and postoperative radiotherapy. A high early recurrence rate, particularly in glioblastoma, has led to the investigation of additional chemotherapy. Material and Methods: Recent results of radiochemotherapy published in the literature were reviewed with respect to outcome in phase II and III trials. Based on these experiences, aspects of future strategies were discussed. Results: 3 decades of intensive research had, unfortunately, little impact on the overall results. While early prospective studies established adjuvant nitrosoureas, particularly BCNU, as suitable adjuvant to surgery and postoperative radiotherapy, further studies largely concentrated on combined chemotherapeutic protocols, mostly procarbazine, CCNU and vincristine (PCV), which was shown to prolong survival in anaplastic astrocytoma. The recent MRC study, however, showed no effect for adjuvant PCV in grade III and IV malignant glioma. Only in high-grade glioma with an oligodendroglial component, additional chemotherapy may be of a decisive benefit. The introduction of newer drugs such as paclitaxel, temozolomide, or gemcitabine demonstrated no decisive advantage. Different modes of application and sequencing of radiotherapy and chemotherapy are presently actively investigated, but failed to substantially improve outcome. Conclusions: Therefore, search for newer and more effective drugs continues, as well as for ''optimal'' administration and sequencing, especially from the standpoint of accompanying acute and late toxicity. Finally, recent endeavors focused on basic research such as angiogenesis, migration and invasion, or induction of cell differentiation, but these strategies are still away from broader clinical investigation.

    Biological wound dressings sterilized with gamma radiation, such as amnion and pig skin, are a reality in Mexico. These tissues are currently processed in the tissue bank and sterilized in the Gamma Industrial Irradiation Plant; both facilities belong to the Instituto Nacional de Investigaciones Nucleares (ININ) (National Institute of Nuclear Research). With the strong support of the International Atomic Energy Agency, the bank was established at the ININ and the Mexican Ministry of Health issued its sanitary license on July 7, 1999. The Quality Management System of the bank was certified by ISO 9001:2000 on August 1, 2003; the scope of the system is "Research, Development and Processing of Biological Tissues Sterilized with Gamma Radiation". At present, more than 150 patients from 16 hospitals have been successfully treated with these tissues. This paper presents a brief description of the tissue processing, as well as the present Mexican clinical experience with children and adult patients who underwent medical treatment with radiosterilized amnion and pig skin, used as biological wound dressings on burns and ocular surface disorders.

    Full Text Available OBJECTIVE: As the first laboratory to offer massively parallel sequencing-based noninvasive prenatal testing (NIPT for fetal aneuploidies, Sequenom Laboratories has been able to collect the largest clinical population experience data to date, including >100,000 clinical samples from all 50 U.S. states and 13 other countries. The objective of this study is to give a robust clinical picture of the current laboratory performance of the MaterniT21 PLUS LDT. STUDY DESIGN: The study includes plasma samples collected from patients with high-risk pregnancies in our CLIA-licensed, CAP-accredited laboratory between August 2012 to June 2013. Samples were assessed for trisomies 13, 18, 21 and for the presence of chromosome Y-specific DNA. Sample data and ad hoc outcome information provided by the clinician was compiled and reviewed to determine the characteristics of this patient population, as well as estimate the assay performance in a clinical setting. RESULTS: NIPT patients most commonly undergo testing at an average of 15 weeks, 3 days gestation; and average 35.1 years of age. The average turnaround time is 4.54 business days and an overall 1.3% not reportable rate. The positivity rate for Trisomy 21 was 1.51%, followed by 0.45% and 0.21% rate for Trisomies 18 and 13, respectively. NIPT positivity rates are similar to previous large clinical studies of aneuploidy in women of maternal age ≥ 35 undergoing amniocentesis. In this population 3519 patients had multifetal gestations (3.5% with 2.61% yielding a positive NIPT result. CONCLUSION: NIPT has been commercially offered for just over 2 years and the clinical use by patients and clinicians has increased significantly. The risks associated with invasive testing have been substantially reduced by providing another assessment of aneuploidy status in high-risk patients. The accuracy and NIPT assay positivity rate are as predicted by clinical validations and the test demonstrates improvement in the

    Abstract Flexible bronchoscopy is more and more used for diagnosis and management of various pulmonary diseases in pediatrics. As poor coordination of children, the procedure is usually performed under general anesthesia with spontaneous or controlled ventilation to increase children and bronchoscopists’ safety and comfort. Previous studies have reported that dexmedetomidine (DEX) could be safely and effectively used for flexible bronchoscopy in both adulate and children. However, there is no trial to evaluate the dose-finding of safety and efficacy of dexmedetomidine-remifentanil (DEX-RF) in children undergoing flexible bronchoscopy. The objective of this study is to evaluate the dose-finding of safety and efficacy of DEX-RF in children undergoing flexible bronchoscopy. One hundred thirty-five children undergoing flexible bronchoscopy with DEX-RF were divided into 3 groups: Group DR1 (n = 47, DEX infusion at 0.5 μg·kg–1 for 10 minutes, then adjusted to 0.5–0.7 μg kg–1 h–1; RF infusion at 0.5 μg kg–1 for 2 minutes, then adjusted to 0.05–0.2 μg kg–1 min–1), Group DR2 (n = 43, DEX infusion at 1 μg kg–1 for 10 minutes, then adjusted to 0.5–0.7 μg kg–1 h–1; RF infusion at 1 μg kg–1 for 2 minutes, then adjusted to 0.05–0.2 μg kg–1 min–1), Group DR3 (n = 45, DEX infusion at 1.5 μg kg–1 for 10 minutes, then adjusted to 0.5–0.7 μg kg–1 h–1; RF infusion at 1 μg kg–1 for 2 minutes, then adjusted to 0.05–0.2 μg kg–1 min–1). Ramsay sedation scale of the 3 groups was maintained 3.

    The aim of this study was to compare helical CT with fiberoptic bronchoscopy findings to appraise the medium-term results of proximal-airways stenting. Twenty-five patients with 28 endobronchial metallic stents inserted for local advanced malignancy (n=13) or benign diseases (n=12) underwent follow-up CT from 3 days to 50 months (mean 8 months). All studies were obtained using helical CT with subsequent multiplanar reformation and three-dimensional reconstruction including virtual bronchoscopy. The location, shape, and patency of stents and adjacent airway were assessed. The results of CT were compared with the results of fiberoptic bronchoscopy obtained with a mean delay of 2.5 days (SD 9 days) after CT scan. Twelve stents (43%) remained in their original position, patent and without deformity. Sixteen stents were associated with local complications: migration (n=6); external compression with persistent stenosis (n=4); local recurrence of malignancy (n=4); fracture (n=1); and non-congruence between the airway and the stent (n=1). The CT demonstrated all the significant abnormalities demonstrated at fiberoptic bronchoscopy except two moderate stenoses (20%) related to granulomata at the origin of the stent. Ten of 14 stents inserted for benign conditions were without complications as compared with 2 of 14 in malignant conditions (p=0.008). Computed tomography is an accurate noninvasive method for evaluating endobronchial stents. The CT is a useful technique for follow-up of patients who have undergone endobronchial stenting. (orig.)

    Students often work with clients from a cultural group different than their own. This is especially true for students completing clinical practica in Appalachia, where there is a culture unique to that geographic area. To prepare for this unique setting, common cultural scenarios experienced in the clinical setting must be addressed to help provide culturally appropriate patient care while developing required clinical competencies. Although applicable to most nursing students, the author discusses culturally specific approaches to clinical care of clients from Appalachia, specifically applied to nurse practitioner students, preceptors, and clinical faculty.

    Full Text Available OBJECTIVE - To describe clinical observations of marked improvement in ventricular dysfunction in a medical office environment under circumstances differing from those in study protocols and multicenter studies performed in hospital or with outpatient cohorts. METHODS - Eleven cardiac failure patients with marked ventricular dysfunction receiving treatment at a doctors office between 1994 and 1999 were studied. Their ages ranged from 20 and 66 years (mean 39.42±14.05 years; 7 patients were men, 4 were women. Cardiopathic etiologies were arterial hypertension in 5 patients, peripartum cardiomyopathy in 2, nondefined myocarditis in 2, and alcoholic cardiomyopathy in 4. Initial echocardiograms revealed left ventricular dilatation (average diastolic diameter, 69.45±8.15mm, reduced left ventricular ejection fraction (0.38±0.08 and left atrial dilatation (43.36±5.16mm. The therapeutic approach followed consisted of patient orientation, elimination of etiological or causal factors of cardiac failure, and prescription of digitalis, diuretics, and angiotensinconverting enzyme inhibitors. RESULTS - Following treatment, left ventricular ejection fraction changed to 0.63±0.09; left ventricular diameters changed to 57.18±8.13mm, and left atrium diameters changed to 37.27±8.05mm. Maximum improvement was noted after 16.9±8.63 (6 to 36 months. CONCLUSION - Patients with serious cardiac failure and ventricular dysfunction caused by hypertension, alcoholism, or myocarditis can experience marked improvement in ventricular dysfunction after undergoing appropriate therapy within the venue of the doctor's office.

    Full Text Available Aim: The aim of the study was to compare transcricoid injection with "spray as you go" technique for diagnostic fibreoptic bronchoscopy, to perform the procedure without sedation and to record any complication or side effects. Methods: Sixty patients belonging to the age group 20-70 years, undergoing diagnostic bronchoscopy over a period of 6 months, were randomly selected and divided into two groups alternatively to receive 3 ml of 4% lignocaine by a single transcricoid puncture (group I or 2 ml of 4% lignocaine instilled through the bronchoscope on to the vocal cords and further 1 ml of 2% lignocaine into each main bronchus (group II. Additional dose of lignocaine as required was given in both the groups. All patients were given intramuscular atropine 0.6 mg, 20 min before the procedure. Nebulisation with 3 ml of 4% lignocaine was given to all patients. The time from nasal insertion of the bronchoscope to reach the carina was recorded, and the total dose of lignocaine required in both the groups was calculated and compared. The cough episodes during the procedure, systolic blood pressure, and pulse rate were compared before the procedure and 5 min after the procedure in both the groups. A 0-10 visual analogue scale (VAS was used to assess discomfort 30 min after the procedure. Results: The time to reach carina was more in group II (P<0.02, and cough episodes were also more in group II (P<0.05 than in group I. The vitals before the procedure were comparable in both the groups, but 5 min after the procedure the vitals were more stable in group I than in group II, and the total dose of lignocaine required in group II was more than in group I (P<0.001. However, the VAS score was comparable in both the groups. Conclusion: Transcricoid puncture for diagnostic bronchoscopies without sedation was associated with no complication and discomfort and required lesser dose of local anaesthetic with more stable vitals and good conditions for bronchoscopists.

    This article explores specific aspects of self-reported clinical and research experience and their relationship to performance in medical training. This is a retrospective cohort study conducted at the Uniformed Services University. The American Medical College Application Service application was used to discern students' self-reported clinical and research experience. Two authors applied a classification scheme for clinical and research experience to the self-reported experiences. Study outcomes included medical school grade point average (GPA), U.S. Medical Licensing Examination (USMLE) scores, and intern expertise and professionalism scores. A linear regression analysis was conducted for each outcome while controlling for prematriculation GPA. Data were retrieved on 1,020 matriculants. There were several statistically significant but small differences across outcomes when comparing the various categories of clinical experience with no clinical experience. The technician-level experience group had a decrease of 0.1 in cumulative GPA in comparison to students without self-reported clinical experience (p = 0.004). This group also performed 5 points lower on the USMLE Step 2 than students who did not report clinical experience (p = 0.013). The various levels of self-reported research experience were unrelated to success in medical school and graduate medical education. These findings indicate that self-reported technician-level clinical experience is related to a small reduction in typically reported outcomes in medical school.

    2013-03-01

    Full Text Available Lung cancer has become a complicated health problem in the world. In 2005, approximately 172,500 people diagnosed with lung cancer in the United States. In Indonesia, lung cancer ranks fourth highest. Lung cancer is also the most common cause of death from cancer, so we need appropriate early detection modality to reduce the number of deaths from lung cancer. Compared with other modalities that currently available, Autofluorescence Bronchoscopy (AFB seems to have better accuracy in early diagnosis of lung cancer. AFB can be used to evaluate patients with high-grade sputum atypia, evaluating patients with suspected or had suffered from lung cancer, and have a role in follow-up of bronchial high-grade intraepithelial neoplasia.

    This study compared the effect of simulation and clinical experience timing on self-confidence/self-efficacy for the nursing process. Using a randomized, double-crossover design, self-efficacy was measured 3 times. Although self-efficacy was significantly higher at time 1 for students who had clinical experience, there was no difference between the groups at the end of the course (time 2). Thus, simulation increased self-confidence/self-efficacy equivalently if placed either before or after clinical experience.

    Impressive clinical reports have come from several major spinal research centers regarding the results of using the AO spinal internal fixator, a recently released pedicle screw rod system. A retrospective review of the first 2 years of clinical results from a diverse group of orthopedic surgeons using this device at a Canadian University center may provide some insight into potential clinical outcomes in general use. These results contrast with the outcome data provided to date, which have been presented by expert academic spinal surgeons. The results suggest that there may be room for considering limited release of this device, perhaps with the requirement for special certification in its application.

    Photoacoustic imaging has evolved into a clinically translatable platform with the potential to complement existing imaging techniques for the management of cancer, including detection, characterization, prognosis, and treatment monitoring. In photoacoustic imaging, tissue is optically excited to produce ultrasonographic images that represent a spatial map of optical absorption of endogenous constituents such as hemoglobin, fat, melanin, and water or exogenous contrast agents such as dyes and nanoparticles. It can therefore provide functional and molecular information that allows noninvasive soft-tissue characterization. Photoacoustic imaging has matured over the years and is currently being translated into the clinic with various clinical studies underway. In this review, the current state of photoacoustic imaging is presented, including techniques and instrumentation, followed by a discussion of potential clinical applications of this technique for the detection and management of cancer.

    Sporotrichosis in an uncommon mycoses in childhood and is generally associated with injuries received as a consequence of farm work. We undertook a retrospective study of sporotrichosis in children and adolescents seen over a 10-year period, focusing on their clinical, epidemiologic, and mycologic features as well as treatment. We included 25 children with a mean age of 9.3 years. Most of those affected were schoolchildren (84%) from rural areas. The main clinical variety of sporotrichosis seen was the lymphocutaneous form (64%), followed by the fixed cutaneous form (36%), and one instance of the disseminated cutaneous form. Most lesions were located on the upper limbs (40%) and the face (36%). Sporothrix schenckii was isolated in all patients and 24 of 25 had a positive sporotrichin skin test. Nineteen patients were treated and cured clinically and mycologically with potassium iodide, three were cured with itraconazole and one with heat therapy.

    As dental schools continue to seek the most effective ways to provide clinical education for students, it is important to track the effects innovations have on students' clinical experience to allow for quantitative comparisons of various curricula. The aim of this study was to compare the impact of three successive clinical curricula on students' experience at one U.S. dental school. The three were a discipline-based curriculum (DBC), a comprehensive care curriculum (CCC), and a procedural requirement curriculum plus externships (PRCE). Students' clinic experience data from 1992 to 2013 were analyzed for total experience and in five discipline areas. Clinic experience metrics analyzed were patient visits (PVs), relative value units (RVUs), and equivalent amounts (EQAs). A minimum experience threshold (MET) and a high experience threshold (HET) were set at one standard deviation above and below the mean for the DBC years. Students below the MET were designated as low achievers; students above the HET were designated as high achievers. The results showed significant differences among the three curricula in almost all areas of comparison: total PVs, total EQAs, total RVUs, RVUs by discipline, and number of high and low achievers in total clinical experience and by discipline. The comprehensive care approach to clinical education did not negatively impact students' clinical experience and in many cases enhanced it. The addition of externships also enhanced student total clinical experience although more study is needed to determine their effectiveness. The insights provided by this study suggest that the methodology used including the metrics of PVs, EQAs, and RVUs may be helpful for other dental schools in assessing students' clinical experience.

    2007-06-01

    In the previous paper in this series, basic mechanisms of electrode related injuries were discussed. In this paper, the discussion begins with some of the clinical aspects of burns. This is followed by a summary of the clinical literature on injuries produced by surface and subdermal electrodes. This clinical literature demonstrates that most electrode burns are related to the presence of high frequency electric fields (RF) created either by an electrosurgical unit or a magnetic resonance imaging (MRI) scanner. A smaller number of lesions are produced by low current, long duration direct current (DC) stimulation and during high current stimulation such as defibrillation. A discussion of the clinical complications from indwelling intracranial electrodes centers on electrodes placed for deep brain stimulation (DBS) that are currently used therapeutically in a wide array of neurologic disorders. The probability of considering a post-implant MRI scan is high and the safety of such scans is the focus of discussion. A very small number of adverse incidents have indicated a downward revision in the specific absorption rate recommendations for MRI examination with those patients who present with indwelling DBS leads and internal pulse generators. Continued vigilance when any type of electrode is used is important.

    It is expected that the incidence of various adverse effects of anticancer agents maybe decreased owing to the reduced drug distribution in normal tissue. Anticancer agent incorporating nanoparticles including micelles and liposomes can evade non-specific capture by the reticuloendothelial system because the outer shell of the nanoparticles is covered with polyethylene glycol. Consequently, the micellar and liposomal carrier can be delivered selectively to a tumor by utilizing the enhanced permeability and retention effect. Presently, several anticancer agent-incorporating nano-carrier systems are under preclinical and clinical evaluation. Several drug delivery system formulations have been approved worldwide. Regarding a pipeline of clinical development of anticancer agent incorporating micelle carrier system, several clinical trials are now underway not only in Japan but also in other countries. A Phase 3 trial of NK105, a paclitaxel incorporating micelle is now underway. In this paper, preclinical and clinical studies of NK105, NC-6004, cisplatin incorporating micelle, NC-6300, epirubicin incorporating micelle and the concept of cancer stromal targeting therapy using nanoparticles and monoclonal antibodies against cancer related stromal components are reviewed.

    The purpose of this study was to determine the diagnostic accuracy of synthetic MR sequences generated through post-acquisition processing of a single sequence measuring inherent R1, R2, and PD tissue properties compared with sequences acquired conventionally as part of a routine clinical pediatric brain MR exam. Thirty-two patients underwent routine clinical brain MRI with conventional and synthetic sequences acquired (22 abnormal). Synthetic axial T1, T2, and T2 fluid attenuation inversion recovery or proton density-weighted sequences were made to match the comparable clinical sequences. Two exams for each patient were de-identified. Four blinded reviewers reviewed eight patients and were asked to generate clinical reports on each exam (synthetic or conventional) at two different time points separated by a mean of 33 days. Exams were rated for overall and specific finding agreement (synthetic/conventional and compared to gold standard consensus review by two senior reviewers with knowledge of clinical report), quality, and diagnostic confidence. Overall agreement between conventional and synthetic exams was 97%. Agreement with consensus readings was 84% (conventional) and 81% (synthetic), p = 0.61. There were no significant differences in sensitivity, specificity, or accuracy for specific imaging findings involving the ventricles, CSF, brain parenchyma, or vasculature between synthetic or conventional exams (p > 0.05). No significant difference in exam quality, diagnostic confidence, or noise/artifacts was noted comparing studies with synthetic or conventional sequences. Diagnostic accuracy and quality of synthetically generated sequences are comparable to conventionally acquired sequences as part of a standard pediatric brain exam. Further confirmation in a larger study is warranted. (orig.)

    Quality assurance programs have been established during the last two decades in developed countries to promote high quality performance in clinical laboratories. In Taiwan, such a program for clinical microbiology laboratories has been in place since July 1987. It has been supported by the Department of Health, Executive Yuan, R.O.C. and was set up by the authors. The manpower status, facilities and equipment, and performance of clinical laboratories were investigated during the first year and standards of laboratory quality were recommended. Since then, under a continuing education program, we have conducted seminars, symposia, workshops, short-courses or panel discussions approximately 4 times a year. There have been about 150 participants per session and they have come from local hospitals (primary care hospitals), regional hospitals (secondary care hospitals) and medical centers (tertiary care hospitals). Proficiency test specimens or external unknown specimens were sent to all the laboratories twice a year and approximately 3 specimens were used each time for the evaluation of each laboratory's diagnostic capability and quality of service. Results indicated that there were tremendous improvements in the quality of laboratory performance. At the same time, several laboratory manuals describing the methods of quality control of clinical specimens, test procedures, media and reagents, personnel management and a compilation of reports etc. were published as guidelines of basic requirements for each level of the laboratories. For local hospital laboratories in remote areas, several regional hospitals or medical centers with high quality laboratories were selected to serve as back-ups. Our evaluation has shown that the performance and quality of service provided by most clinical microbiology laboratories in Taiwan have now reached nearly the level of those found in the so-called "developed countries".

    Dealing with emotions is a critical feature of professional behaviour. There are no comprehensive theoretical models, however, explaining how medical students learn about emotions. We aimed to explore factors affecting their emotions and how they learn to deal with emotions in themselves and others. During a first-year nursing attachment in hospitals and nursing homes, students wrote daily about their most impressive experiences, explicitly reporting what they felt, thought, and did. In a subsequent interview, they discussed those experiences in greater detail. Following a grounded theory approach, we conducted a constant comparative analysis, collecting and then interpreting data, and allowing the interpretation to inform subsequent data collection. Impressive experiences set up tensions, which gave rise to strong emotions. We identified four 'axes' along which tensions were experienced: 'idealism versus reality', 'critical distance versus adaptation', 'involvement versus detachment' and 'feeling versus displaying'. We found many factors, which influenced how respondents relieved those tensions. Their personal attributes and social relationships both inside and outside the medical community were important ones. Respondents' positions along the different dimensions, as determined by the balance between attributes and tensions, shaped their learning outcomes. Medical students' emotional development occurs through active participation in medical practice and having impressive experiences within relationships with patients and others on wards. Tensions along four dimensions give rise to strong emotions. Gaining insight into the many conditions that influence students' learning about emotions might support educators and supervisors in fostering medical students' emotional and professional development.

    2006-09-01

    The elaboration of more reliable and simple methods of transmitted and plexus anestesias has provided a wide clinical usage of regionar anestesia (RA) during the operations on extremities. The creation of devices to identificate (locate) nerval bearer and plexes was also an important factor for increasing quantity of RA. For such identification we use the portable "Innervator 232" neurostimulator manufactured by "Fisher & Paykel Ltd.", New Zealand. Successful conduction of transmitted and plexus anesthesia depends a lot on anesthesiologist's knowledge of anatomy-topography location of nerval bearer and plexes, precise fulfillment of anesthesia, manual capabilities of physician and obtaining a paresthesia or muscular contraction during the identification of nerval bearer with the help of neurostimulator. RA is secure, effective, and provides less risk for a patient. With neurostimulation the amount of successful anesthesias increases up to 98%. The neurostimulator is easy to use, clinically effective in emergency and planned surgeries for identification of nerval bearer and plexes.

    Full Text Available Aims: Tuberculous infection of the thoracic cage is rare and is difficult to discern clinically or on radiographs. This study aims to describe the common sites and the imaging appearances of chest wall tuberculosis. Materials and Methods: A retrospective review of the clinical and imaging records of 12 confirmed cases of thoracic cage tuberculosis (excluding that of the spine, seen over the last 7 years, was performed. Imaging studies available included radiographs, ultrasonographies (USGs, and computed tomography (CT scans. Pathological confirmation was obtained in all cases. Results: All patients had clinical signs and symptoms localized to the site of involvement, whether it was the sternum, sternoclavicular joints, or ribs. CT scan revealed sternal destruction in three patients and osteolytic lesions with sclerosis of the articular surfaces of the sternoclavicular joints in two patients. In five patients with rib lesions, USG elegantly demonstrated the bone destruction underlying the cold abscess. All cases were confirmed to be of tuberculous origin by pathology studies of the aspirated/curetted material, obtained by CT / USG guidance. Conclusions: Tuberculous etiology should be considered for patients presenting with atypical sites of skeletal inflammation. CT scan plays an important role in the evaluation of these patients. However, the use of USG for demonstrating rib destruction in a chest wall cold abscess has so far been under-emphasized, as has been the role of CT and USG guided aspiration in confirming the aetiology.

    Full Text Available Objective: In 2015, the Centers for Medicare and Medicaid Services (CMS released new summary star ratings for US hospitals based on patient experience. We aimed to test the association between CMS patient experience star ratings and clinical outcomes. Methods: We analyzed risk-adjusted data for more than 3000 US hospitals from CMS Hospital Compare using linear regression. Results: We found that better patient experience was associated with favorable clinical outcomes. Specifically, a higher number of stars for patient experience had a statistically significant association with lower rates of many in-hospital complications. A higher patient experience star rating also had a statistically significant association with lower rates of unplanned readmissions to the hospital within 30 days. Conclusion: Better patient experience according to the CMS star ratings is associated with favorable clinical outcomes. These results support the inclusion of patient experience data in the framework of how hospitals are paid for services.

    The aim of the study was to develop a multi-disciplinary stress management program for employees with long-term stress. In a two-year period, 66 people active in the labour market were referred to the stress clinic at an occupational medicine clinic. All but 10 went through the program for four months and were further evaluated after one year regarding employment, symptoms and salivary cortisol. The program consisted of 1) an evaluation of symptoms of depression and stress, 2) stress management consultations, 3) introduction to relaxation techniques and physical exercise and 4) in some cases contact to the work place for adjustments or referral to psychiatric evaluation. Physiological measures such as maximal oxygen uptake, blood pressure, cholesterol, HDL, TSH, HbA1C, fasting glucose and fibrinogen were carried out at baseline and after four months. Salivary cortisol was measured at baseline, after four months and one year. As a control group 24 people with similar symptoms referred to the Clinic of Occupational Medicine were used. A significantly larger number of people in the study group (82%) than in the control group (42%) were employed after one year. There was no difference between the two groups regarding the prevalence of stress symptoms during the follow-up period, even though the prevalence decreased significantly. However, the prevalence of depression was significantly lower after one year in the study group (4%) compared to the control group (40%). Maximum oxygen uptake increased and fibrinogen decreased significantly in four months. The rise in salivary cortisol from awakening until 30 minutes later increased significantly during one year and correlated with symptoms of depression.

    The Patient Perceptions of Corrective Experiences in Individual Therapy (PPCEIT; Constantino, Angus, Friedlander, Messer, & Moertl, 2011) posttreatment interview guide was developed to provide clinical researchers with an effective mode of inquiry to identify and further explore clients' firsthand accounts of corrective and transformative therapy experiences and their determinants. Not only do findings from the analysis of client corrective experience (CE) accounts help identify what and how CEs happen in or as a result of psychotherapy, but the measure itself may also provide therapists with an effective tool to further enhance clients' awareness, understanding, and integration of transformative change experiences. Accordingly, we discuss in this afterword to the series the implications for clinical practice arising from (a) the thematic analysis of client CE accounts, drawn from a range of clinical samples and international research programs and (b) the clinical effect of completing the PPCEIT posttreatment interview inquiry. We also identify directions for future clinical training and research. © 2016 Wiley Periodicals, Inc.

    2000-10-01

    The usual hemodynamic response to laryngoscopy and bronchoscopy is an increase in heart rate and arterial blood pressure. Previous work has reported that 10%-18% of the patients develop ischemic ST segment changes during the procedure. Therefore, we performed a prospective, randomized, double-blinded study in 36 patients scheduled for elective microlaryngeal and bronchoscopic surgical procedures to evaluate the effects of 300-microg oral clonidine premedication (n = 18) or placebo (n = 18) on the hemodynamic alterations and the incidence of perioperative myocardial ischemic episodes. Myocardial ischemia was assessed by using continuous electrocardiographic monitoring, beginning 30 min before, and lasting until 24 h after the operation. During the procedure, patients receiving placebo exhibited a significant increase (mean +/- SD) in arterial blood pressure (the systolic increasing from 137+/-11 to 166+/-17 mm Hg, the diastolic increasing from 80+/-11 to 97+/-14 mm Hg) and heart rate (increasing from 79+/-15 to 97+/-12 bpm) compared with the baseline and with the clonidine group. A dose of 300-microg clonidine blunted the hemodynamic response to endoscopy. Ventricular arrhythmias were more frequent in patients who were not premedicated with clonidine. Two patients in the control group, but none in the clonidine group, had evidence of myocardial ischemia. These data should encourage routine premedication with clonidine in patients undergoing microlaryngoscopic and bronchoscopic procedures.

    In order to reduce the side-effects (blood-lipid alterations, androgen effects etc.) new gestogens were introduced, while the ethinyl-estradiol component of the pill was unchanged. Authors report about clinical trial on monophasic oral contraceptive containing 0.030 mg ethinyl-estradiol and 0.075 mg gestodene. In a follow up of 92 women, in 1740 cycles no pregnancy and no cardivascular or thromboembolic complication was observed. The frequency of bleeding disorders was below 10% already in the first cycle. The quantity of withdrawal bleeding, as well the frequency of breakthrough bleeding and spotting decreased during the treatment. Significant alteration in body weight or blood pressure did not occur. Femoden containing third generation gestogen has an excellent cycle control and good patient compliance.

    2016-08-01

    This article describes reasoning strategies used by clinicians in different diagnostic circumstances and how these modes of inquiry may allow further insight into the evaluation and treatment of patients. Specifically, it aims to make explicit the implicit logical considerations that guide a variety of strategies in the diagnostic process, as exemplified in specific clinical cases. It focuses, in particular, in strategies that clinicians use to move from a large set of possible diagnoses initially suggested by abductive inferences - the process of hypothesis generation that creates a diagnostic space - to a narrower set or even to a single 'best' diagnosis, where the criteria to determine what is 'best' may differ according to different strategies. Experienced clinicians should have a diversified kit of strategies - for example, Bayesian probability or inference to a lovely explanation - to select from among previously generated hypotheses, rather than rely on any one approach every time.

    The thyroglossal duct cyst pathology represents the second cause of bening cervical anomalies in childhood. Diagnosis is mainly clinical. Sistrunk (1920) proposed a surgical technique that is still considered the gold standard for definitive treatment of this condition. A retrospective study was made including patients who underwent surgery for thyroglossal duct cyst pathology in our department between June 2008 and August 2015. In this period, we performed 54 procedures in 45 patients (39 primary cases). Median age was 4.7 years; 14/39 patients (31.1%) had pre-operative infection. All patients were studied with neck ultrasound. A Sistrunk's procedure was performed in all cases. The global recurrence rate was 17.8% (8/45).

    The effect of radiation therapy for Graves` ophthalmopathy was evaluated. Ten patients with Graves` ophthalmopathy were treated with radiation therapy between 1992 and 1993 in Gunma University Hospital. All patients had a past history of hyperthyroidism and received 2,000 cGy to the retrobulbar tissues in 20 fractions. Nine of ten patients were treated with radiation therapy after the failure of corticosteroids. Six patients (60%) showed good or excellent responses. The exophthalmos type was more responsive to radiation therapy than the double vision type in this series. Two of five patients with the exophthalmos type demonstrated excellent responses, and their symptoms disappeared almost completely. The improvement of symptoms appeared within 3-6 months, and obvious clinical effects were demonstrated after 6 months of radiotherapy. Radiation therapy was well tolerated, and we have not observed any side effects of radiation therapy. In conclusion, radiation therapy is effective treatment for Graves` ophthalmopathy. (author)

    Flexible bronchoscopy has been more and more used for diagnosis and management diseases of respiratory system in pediatrics. Previous studies have reported that remifentanil (RF) and propofol are safe and effective for flexible bronchoscopy in adults, however, there have no trials evaluate the efficacy of DEX-RF versus dexmedetomidine-propofol in children undergoing flexible bronchoscopy.We divided 123 children undergoing flexible bronchoscopy with DEX-RF or dexmedetomidine-propofol into 2 groups: Group DR (n = 63, DEX infusion at 1.0 μg kg for 10 minutes, then adjusted to 0.5-0.7 μg kg h; RF infusion at 1.0 μg kg for 5 minutes, then adjusted to 0.05-0.2 μg kg min), Group DP (n = 60, DEX infusion at 1.0 μg kg for 10 minutes, then adjusted to 0.5-0.7 μg kg h; propofol infusion at 10 μg kg for 5 minutes, then adjusted to 0.05-0.1 μg kg min). Ramsay sedation scale of the 2 groups was maintained at 3. Anesthesia onset time; total number of intraoperative patient movements; hemodynamics; total cumulative dose of DEX; amount of and time to first-dose rescue midazolam and lidocaine; postoperative recovery time; adverse events; and bronchoscopist satisfaction score were recorded.Anesthesia onset time was significantly shorter in DP (8.22 ± 2.48 vs 12.25 ± 6.43 minutes, respectively, for DP, DR, P = 0.015). The perioperative hemodynamic profile was more stable in DR than DP group. More children moved during flexible bronchoscopy in DP group (P = 0.009). Total dose of rescue midazolam and lidocaine was significantly higher in DR than in DP (P propofol.

    Cortisone and ACTH are valuable agents for treating a large variety of diseases. In appropriate situations they may save life. It may be possible to prevent loss of vision in eye disease or permanent damage to important viscera in generalized disease. With ready access to these agents through the pharmacist, it is important to know that cortisone and ACTH can be used in office practice provided patients are selected carefully and followed frequently and closely. Strict observation of criteria for selection of patients limited the size of the series of patients reported upon, but by the same token the incidence of complications from therapy was exceptionally small. Every physician who elects to employ these potent hormones must become familiar with their physiological effects and with the various methods of exhibiting them. Some of these effects are noted in this paper, but the experiences reviewed here provide an incomplete picture of the wide application of cortisone and ACTH. PMID:14848715

    This single centre study was designed to demonstrate feasibility, safety and efficacy of the Vivant Z stent (PFM AG, Cologne, Germany). Patients with de novo lesion were recruited. Coronary angioplasty was performed with either direct stenting or after balloon predilatation. Repeated angiogram was performed 6 months later or earlier if clinically indicated. Between January to June 2003, a total of 50 patients were recruited (mean age 55.8 +/- 9 years). A total of 52 lesions were stented successfully. Mean reference diameter was 2.77 mm (+/-0.59 SD, range 2.05-4.39 mm) with mean target lesion stenosis of 65.5% (+/-11.6 SD, range 50.1-93.3%). Forty-six lesions (88.5%) were American College of Cardiologist/American Heart Association class B/C types. Direct stenting was performed in 18 (34.6%) lesions. Mean stent diameter was 3.18 mm (+/-0.41 SD, range 2.5-4 mm), and mean stent length was 14.86 mm (+/-2.72 SD, range 9-18 mm). The procedure was complicated in only one case which involved the loss of side branch with no clinical sequelae. All treated lesions achieved Thrombolysis In Myocardial Infarction 3 flow. Mean residual diameter stenosis was 12.2% (+/-7.55 SD, range 0-22.6%) with acute gain of 1.72 mm (+/-0.50 SD, range 0.5-2.8). At 6 months, there was no major adverse cardiovascular event. Repeated angiography after 6 months showed a restenosis rate of 17% (defined as >50% diameter restenosis). Mean late loss was 0.96 mm (+/-0.48 SD) with loss index of 0.61 (+/-0.38 SD). The restenosis rate of those lesions less than 3.0 mm in diameter was 22.2% compared with 6.25% in those lesions more than 3.0 mm in diameter. The Vivant Z stent was shown to be safe and efficacious with low restenosis rate in de novo coronary artery lesion.

    alpha1-Adrenoreceptors are thought to be involved in prostate smooth muscle contractions and could hence play a role in the dynamic component of intravesical obstruction associated with symptomatic BPH. Consequently, since the mid-eighties alpha receptor blocking agents have been used for the treatment of BPH. Non-selective alpha blockers are usually associated with systemic side-effects which resulted in an exclusion or withdrawal of many patients from this form of treatment. With the availability of so-called uroselective alpha blockers the management picture has changed since it was anticipated that these compounds cause lesser side-effects with at least the same, or even better, efficacy. Comparative clinical studies are essential for determining the eventual advantages of the uroselective alpha1-antagonists and a large number of such studies have been performed worldwide studying the various available compounds. European studies with terazosin showed clear superiority of the drug over the placebo while causing only limited side-effects. Various other studies using alpha-blocking agents such as doxazosin, tamsulosin and alfuzosin yielded identical results. Especially with tamsulosin and alfuzosin, the side-effects were comparable with those encountered in the placebo group. About 7% of the patients using tamsulosin experienced retrograde ejaculation in one study which did not occur in the alfuzosin studies. Important studies in Europe have also investigated the value of a combination of an alpha blocker with a 5alpha-reductase inhibitor. Comparable studies in which both alfuzosin and doxazosin were combined with the 5alpha-reductase inhibitor Proscar have shown that a combination is not superior to a blocker monotherapy and especially in the ALFIN study the results show that alfuzosin monotherapy is superior to Proscar in the management of symptomatic BPH. European studies have evaluated Quality of Life, sexuality as well as socio-economical outcome of the

    Full Text Available Objective: Laparoscopic splenectomy has gained widespread acceptance in the treatment of hematological diseases in recent years. In this study, we aimed to present the outcomes of the patients who underwent laparoscopic splenectomy. Methods: Between 2012 and 2015, the data of 38 patients, who underwent laparoscopic splenectomy for hematological diseases at our clinic, were evaluated retrospectively. Results: 15 males and 23 females patients were underwent laparoscopic splenectomy, and the average age was 33.9 ± 12.9 years. Indications for splenectomy were idiopathic thrombocytopenic purpura (ITP in 34 patients, and hereditary spherocytosis in 4 patients. During the surgical exploration, accessory spleen was detected in 7 patients, and removed. Laparoscopic cholecystectomy was performed at the same session in 2 hereditary spherocytosis patients who had stones in the gallbladder. One patient was converted to the open surgery due to the bleeding which was eliminated the exposure during the dissection. At the postoperative period, we observed atelectasis in one patient, and wound fat necrosis in one patient. In addition, thrombocytosis was observed in one patient. Hematological treatment was continued because of persistent refractory thrombocytopenia in two patients, and temporary thrombocytopenia in four patients. An accessory spleen was detected with splenic scintigraphy in one of these patients at the postoperative period. The average hospitalization time was 2.6 ± 0.7 days. Conclusion: Laparoscopic splenectomy for hematological diseases may be considered as first-line therapy with less hospital stay and morbidity.

    University students in speech-language pathology and nursing were involved in a community service learning project with residents of a long-term care facility who had dementia. Nursing students were asked to interact and converse with residents to the best of their ability (control group, n = 28). Speech-language pathology students were instructed to design a personalized, multi-modality "connection kit" for residents based on the tenets of cognitive linguistic stimulation and facilitative styles of interaction, which were included within course content (experimental group, n = 25). Post-project surveys were administered in an attempt to answer the following research question: Do students perceive benefits from participating in a service learning project involving long-term care residents with dementia? Results revealed that the experimental/trained group of speech-language pathology students reported greater academic and clinical benefits compared to the control group of nursing students. Overall implications were that students benefited from a service learning project, especially when explicit instruction was provided.

    Objective The objective of this study was to profile patients who undergo defecography, by age and gender, as well as to describe the main imaging and diagnostic findings in this population. Materials and Methods This was a retrospective, descriptive study of 39 patients, conducted between January 2012 and February 2014. The patients were evaluated in terms of age, gender, and diagnosis. They were stratified by age, and continuous variables are expressed as mean ± standard deviation. All possible quantitative defecography variables were evaluated, including rectal evacuation, perineal descent, and measures of the anal canal. Results The majority (95%) of the patients were female. Patient ages ranged from 18 to 82 years (mean age, 52 ± 13 years): 10 patients were under 40 years of age; 18 were between 40 and 60 years of age; and 11 were over 60 years of age. All 39 of the patients evaluated had abnormal radiological findings. The most prevalent diagnoses were rectocele (in 77%) and enterocele (in 38%). Less prevalent diagnoses were vaginal prolapse, uterine prolapse, and Meckel's diverticulum (in 2%, for all). Conclusion Although defecography is performed more often in women, both genders can benefit from the test. Defecography can be performed in order to detect complex disorders such as uterine and rectal prolapse, as well as to detect basic clinical conditions such as rectocele or enterocele. PMID:28100932

    Full Text Available Raffaele De CaterinaInstitute of Cardiology and Center of Excellence on Aging, G d’Annunzio University, Chieti, G Monasterio Foundation, Pisa, ItalyAbstract: Atrial fibrillation is an extremely common arrhythmia, which substantially increases the risk of stroke and thromboembolism. Prevention of stroke and thromboembolism is therefore an important part of the management of atrial fibrillation. Guidelines until now have recommended that patients with atrial fibrillation receive some form of antithrombotic therapy, ie, a vitamin K antagonist or aspirin, with a preference for anticoagulants in most cases. However, current treatments are suboptimal, and despite the recommendations, many patients do not receive adequate thromboprophylaxis, because they are considered, for various reasons, “unsuitable” to receive a vitamin K antagonist. In this patient population, apixaban, a new oral anticoagulant inhibiting activated coagulation factor X, administered in fixed doses and without anticoagulation monitoring, has undergone testing against aspirin in the recently published AVERROES trial. This paper addresses the strengths and limitations of this trial and the practical relevance of the new clinical information it provides.Keywords: atrial fibrillation, apixaban, thromboprophylaxis

    We studied 35 pediatric patients with autoimmune hemolytic anemia seen at Mayo Clinic from 1994 to 2014. The median age was 10.0 years and 65.7% were males. Most had warm antibodies (80.0%) and some secondary to viral (14.3%) or autoimmune disorders (31.4%). Seven (20.0%) patients presented with Evans syndrome, 3 of whom also had common variable immunodeficiency. The median hemoglobin at diagnosis was 6.1 g/dL and 62.8% patients required red cell transfusions. The severity of anemia was worse among children below 10 years (median 5.5 vs. 7.0 g/dL, P=0.01). Steroid was the initial treatment for 88.5% patients, with overall response rate of 82.7% (68.5% complete, 14.2% partial) and median response duration of 10.7 months (range, 0.2 to 129.7+ mo). After median follow-up of 26.6 months, 8 (22.8%) patients relapsed. Salvage treatments included splenectomy, intravenous immunoglobulin, rituximab, and mycophenolate mofetil. Infectious complications occurred in 9 (25.7%) patients and 1 patient died of cytomegalovirus infection. Four patients had cold agglutinin disease and 3 (75.0%) responded to steroids. Autoimmune hemolytic anemia is a rare disorder in pediatric population and most respond well to steroids regardless of the type of antibody. Infectious complications are common and screening for immunodeficiency is recommended among those with Evans syndrome.

    2013-09-01

    Full Text Available Considering the academic development of the psychologist as a complex process which articulates the transmission of scientific knowledge and changes in imaginative activity, we psychoanalytically investigate the collective imaginary of Psychology students regarding the first clinical consultation. We conducted a group interview with 52 undergraduate students, using the Thematic Story-Drawing Procedure as a way to open a dialogical field. The material obtained, through the psychoanalytical method, resulted in the creation/gathering of four affective-emotional meaning fields: “I came, I saw and I conquered”, “I know that I (do not know”, “I survived and I will save” and “I am and I do”, from which we see an emotionally immature imaginary about the meeting with the patient, since students are more self-centered than concerned with the patient. The overall situation indicates the need for care regarding student academic development, in order to encourage a more mature approach toward the suffering of the other.

    Full Text Available Abstract Background Logistics handling referrals for gastroscopy may be more time consuming than the examination itself. For the patient, "drop in" gastroscopy may reduce uncertainty, inadequate therapy and time off work. Methods After an 8-9 month run-in period we asked patients, hospital staff and GPs to fill in a questionnaire to evaluate their experience with "drop in" gastroscopy and gastroscopy by appointment, respectively. The diagnostic gain was evaluated. Results 112 patients had "drop in" gastroscopy and 101 gastroscopy by appointment. The number of "drop in" patients varied between 3 and 12 per day (mean 6.5. Mean time from first GP consultation to gastroscopy was 3.6 weeks in the "drop in" group and 14 weeks in the appointment group. The half-yearly number of outpatient gastroscopies increased from 696 before introducing "drop in" to 1022 after (47% increase and the proportion of examinations with pathological findings increased from 42% to 58%. Patients and GPs expressed great satisfaction with "drop in". Hospital staff also acclaimed although it caused more unpredictable working days with no additional staff. Conclusions "Drop in" gastroscopy was introduced without increase in staff. The observed increase in gastroscopies was paralleled by a similar increase in pathological findings without any apparent disadvantages for other groups of patients. This should legitimise "drop in" outpatient gastroscopies, but it requires meticulous observation of possible unwanted effects when implemented.

    The particle or hadron beams deployed in radiotherapy (protons, neutrons and helium, carbon, oxygen and neon ions) have physical and radiobiological characteristics which differ from those of conventional radiotherapy beams (photons) and which offer a number of theoretical advantages over conventional radiotherapy. After briefly describing the properties of hadron beams in comparison to photons, this review discusses the indications for hadrontherapy and analyses accumulated experience on the use of this modality to treat mainly neoplastic lesions, as published by the relatively few hadrontherapy centres operating around the world. The analysis indicates that for selected patients and tumours (particularly uveal melanomas and base of skull/spinal chordomas and chondrosarcomas), hadrontherapy produces greater disease-free survival. The advantages of hadrontherapy are most promisingly realised when used in conjunction with modern patient positioning, radiation delivery and focusing techniques (e.g. on-line imaging, three-dimensional conformal radiotherapy) developed to improve the efficacy of photon therapy. Although the construction and running costs of hadrontherapy units are considerably greater than those of conventional facilities, a comprehensive analysis that considers all the costs, particularly those resulting from the failure of less effective conventional radiotherapy, might indicate that hadrontherapy could be cost effective. In conclusion, the growing interest in this form of treatment seems to be fully justified by the results obtained to date, although more efficacy and dosing studies are required.

    Though frequently observed in children, intussusception is a rare state in adults. The treatment of intussusception in adults is different. In this trial, we have presented intussusception cases in adults that were treated and followed up in our department. The records of 31 adult intussusception cases surgically treated in our department between January 1993 and July 2012 were evaluated retrospectively. Among the 31 adult cases of intussusception that were treated during a period of 19 years, 10 were men, and 21 were women. The mean age was determined as 39.7 ± 5.3. The presentation symptom was abdominal pain in all the patients. Failure to pass gas or feces was observed in 23 patients (74.2 %); nausea and vomiting, in 22 patients (70.9 %); hematochezia, in 16 patients (51.6 %); and weight loss, in 3 patients (9.6 %). The mean duration of symptoms was 4.8 days. Abdominal tenderness was found in all the patients. Muscular defense and rebound tenderness were determined in 13 patients (41.9 %). Findings of intussusception were found in 80.9 % of patients examined by abdominal ultrasonography and in 63.1 % of cases examined by computerized tomography. Resection of the intussuscepted bowel segment was performed in 87 % of the patients. In conclusion, intussusception in adults is a rare clinical entity. Intussusception should be considered in the differential diagnosis in patients presenting with spasmodic abdominal pain, especially in cases with intestinal obstruction. The recommended surgical method is en bloc resection of the intussuscepted segment in cases suspected to carry a risk of malignancy.

    Full Text Available BACKGROUND Control of childhood blindness is one of the priorities identified for achieving the goals of Vision-2020 by WHO. This is considered a priority because blind-years (number of years that a blind person lives after going blind due to childhood blindness are second only to cataract and half of childhood blindness is avoidable (treatable/preventable. Paediatric cataract accounts for 12% of the 1.4 million blind children globally. The prevalence of childhood cataract has been reported as 1 to 15 cases in 10,000 children in developing countries. Compared to industrialised countries, this figure is 10 times higher. Early detection and timely treatment of various childhood disorders such as congenital cataract are the most crucial factors for successful outcome. A suitable measure to address amblyopia and posterior capsule opacification post operatively is imperative for successful visual rehabilitation of such children. The objectives of this study were- 1 To study the clinical profile of paediatric cataract. 2 To evaluate the visual outcome after cataract surgery in these patients. 3 To evaluate different causes of visual impairment following management. MATERIALS AND METHODS A prospective study conducted at Karnataka institute of medical sciences department of ophthalmology from October 2015 to September 2016. All children below 14 years of age presenting with cataract will undergo thorough ophthalmologic examination and cataract surgery. RESULTS The results of the present study with 25 paediatric patients (36 eyes indicates that excellent vision can be expected after cataract surgery and posterior chamber IOL implantation coupled with appropriate amblyopia therapy. CONCLUSION The paediatric cataract patients are referred from primary health centers, and district hospital from north Karnataka to KIMS Hubli. All paediatric patients are from lower socio economic status. Early detection of cataracts and referrals to the ophthalmologist can

    Full Text Available Introduction. Burns are an important public health challenge due to the frequency of getting burns in day-to-day life, occupational hazards, and catastrophes. Treatment of burns is complex and is associated with high morbidity and mortality. Duration and complexity of burn treatment require finding new ways of curing and rehabilitating burns. The result of burn treatment plays a significant role in post-traumatic status of a patient and his or her consequent adaptation in society. Chitosan is a natural safe non-toxic product compatible with human tissues, characterized by hydrosorbid, anticoagulant, antibacterial, and wound healing features. The study aims to  show a clinical application of chitosan-pectin scaffold with cultured human skin fibroblasts in the treatment of deep burns.Methods. The substrate was prepared by dissolving 3% chitosan in 0.5N acetic acid, which was then mixed with 3% solution of pectin dissolved in distillated water. Chitosan film was formed in a Petri dish for 20-24 hours at 20-25 °C. After drying the film, cultured allogeneic fibroblasts (patent number RK-25091 were seeded on its surface.Results. The results from an in vitro culture study showed that human allogeneic fibroblasts could adhere well and grow on the selected scaffold with a typical morphology. During autodermoplasty surgery, cultured allogeneic fibroblasts were applied on granulating wounds of 9 patients with IIIA to IVB degree burns and limited donor resources. Wounds treated with the fibroblast-seeded scaffold among all patients provided the highest level of re-epithelialization (day 5, in comparison to cell-free scaffold (day 7 and untreated surface of wounds (day 10.Conclusion. Our results indicate the potential use of chitosan for wound healing due to its allogenic fibroblast adherence to scaffolding as well as high epithelization. This warrants further studies on chitosan for use in wounds resulting from third and fourth degree burns.

    In the year 2000, the level of methyldibromo glutaronitrile (MDGN) allergy in dermatology clinics in Europe exceeded the level of allergies to all other preservatives, with a prevalence of 3.5%. In the present study, cases of primary sensitization and elicitation to MDGN due to cosmetic products were collected over an 8-month period at the Department of Dermatology, Gentofte University Hospital. The aim was to identify the products related to hand eczema, assess exposure to MDGN in these products and relate the findings to results from a newly developed updated risk assessment model for contact allergy. Out of 24 patients with a positive patch test to MDGN, 17 patients with hand eczema were identified. In 11 of these patients, cosmetic products used in relation to the onset of the disease were shown to contain MDGN (65%). In 8 of these 11 cases, primary sensitization was probable, 5 due to hand/body lotions and 3 due to lotions and/or liquid hand soap. Chemical analysis of 12 products showed that lotions contained 149-390 ppm of MDGN, liquid hand soap 144-399 ppm, a rinsing cream 293 ppm and shampoos 78-79 ppm. The shampoo exposure was not of certain relevance to the eczema. Applying the newly developed updated risk assessment model showed that the concentrations of MDGN in lotions of 149-390 ppm exceeded the calculated maximum acceptable exposure level for MDGN, which would be expected to lead to sensitization in consumers using such products, as seen in the current study. The present cases and updated exposure-based risk assessment process add to the evidence and need for re-defining safe-use concentrations of MDGN in cosmetic products.

    Background Although heart transplantation has become a standard therapy for end-stage heart disease, there are few published studies regarding the use of transplant organs from marginal donors. Here we describe the clinical outcome we have obtained using marginal donor hearts.Methods We analyzed 21 cases of orthotropic heart transplantation for end-stage heart disease performed in our department between September 2008 and July 2010. Of these patients, six received hearts from marginal donors and the remainder received standard-donor hearts. The two groups were compared in terms of both mortality and the incidence of perioperative complications such as infection, acute rejection, and right heart insufficiency.Results The 1-year survival rate of both groups was 100%. Only one death was recorded in standard-donor group during follow-up. Patients who received marginal donor hearts (83%) experienced more early complications than did the standard-donor-heart group (13%), but the mortality of the two groups was the same. The duration of post-ICU stay was greater in the marginal donor group than in the standard-donor group, (35.5±17.4) days and (21.7±2.6) days, respectively (P <0.05).Conclusions The use of marginal donor hearts increases the number of patients who can receive and benefit from transplants. However, it may introduce an increased risk of early complications, thus care should be taken both in the choice of patients who will receive marginal donor hearts and in the perioperative treatment of those for whom the procedure is performed.

    Spasticity is a common symptom among patients with multiple sclerosis (MS). This study aims to assess the effectiveness and safety of the combination of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) in clinical practice for the treatment of spasticity in MS. Retrospective observational study with patients treated with inhaled THC/CBD between April 2008 and March 2012. Descriptive patient and treatment variables were collected. Therapeutic response was evaluated based on the doctor's analysis and overall impression. Of the 56 patients who started treatment with THC/CBD, 6 were excluded because of missing data. We evaluated 50 patients (42% male) with a median age 47.8 years (25.6-76.8); 38% were diagnosed with primary progressive MS, 44% with secondary progressive MS, and 18% with relapsing-remitting MS. The reason for prescribing the drug was spasticity (44%), pain (10%), or both (46%). Treatment was discontinued in 16 patients because of ineffectiveness (7 patients), withdrawal (4), and adverse effects (5). The median exposure time in patients whose treatment was discontinued was 30 days vs 174 days in those whose treatment continued at the end of the study. THC/CBD was effective in 80% of patients at a median dose of 5 (2-10) inhalations/day. The adverse event profile consisted of dizziness (11 patients), somnolence (6), muscle weakness (7), oral discomfort (2), diarrhoea (3), dry mouth (2), blurred vision (2), agitation (1), nausea (1), and paranoid ideation (1). THC/CBD appears to be a good alternative to standard treatment as it improves refractory spasticity in MS and has an acceptable toxicity profile. Copyright © 2013 Sociedad Española de Neurología.

    How do university training and subsequent practical experience affect expertise in clinical psychology? To answer this question we developed methods to assess psychological knowledge and the competence to diagnose, construct case conceptualizations, and plan psychotherapeutic treatment: a knowledge test and short case studies in a first study, and a complex, dynamically evolving case study in the second study. In our cross-sectional studies, psychology students, trainees in a certified postgraduate psychotherapist curriculum, and behavior therapists with more than 10 years of experience were tested (100 in total: 20 each of novice, intermediate, and advanced university students, postgraduate trainees, and therapists). Clinical knowledge and competence increased up to the level of trainees but unexpectedly decreased at the level of experienced therapists. We discuss the results against the background of expertise research and the training of clinical psychologists (in Germany). Important factors for the continuing professional development of psychotherapists are proposed. PMID:23543213

    A consultation model between primary care physicians and psychiatrists that has been in operation for 12 years in the Jerusalem district of the Clalit Health Services in Israel is evaluated. In this model psychiatrists provide consultations twice a month at the primary care clinic. All patients are referred by their family physicians. Communication between the psychiatric consultant and the referring physician is carried out by telephone, correspondence and staff meetings. Evaluation of the psychiatric care consultation model in which a psychiatrist consults at the primary care clinic. A questionnaire-based survey distributed to 17 primary care physicians in primary care clinics in Jerusalem in which a psychiatric consultant is present. Almost all of the doctors (93%) responded that the consultation model was superior to the existing model of referral to a secondary psychiatric clinic alone and reduced the workload in caring for the referred patients. The quality of psychiatric care was correlated with the depression prevalence among patients referred for consultation at their clinic (r=0.530, p=0.035). In addition, correlation was demonstrated between primary care physicians impression of alleviation of care of patients and their impression of extent of the patients' cooperation with the consulting psychiatrist (r=0.679, p = 0.015) Conclusions: Very limited conclusions may be drawn from this questionnaire distributed to primary care physicians who were asked to assess psychiatric consultation in their clinic. Our conclusion could be influenced by the design and the actual distribution of the questionnaires by the consulting psychiatrist. Nevertheless answers to the questionnaire might imply that the consultation model of care between a psychiatric consultant and the primary care physician, where the patient's primary care physician takes a leading role in his psychiatric care, is perceived by family physicians as a good alternative to referral to a psychiatric

    Participating in global health care through international clinical education may enhance the development of cultural competence and professionalism. Many logistical issues need to be resolved in the development of international clinical education experiences that meet program requirements. The purpose of this case report is to describe how a university developed such an experience for students by partnering with Amizade Global Service-Learning (Amizade), an organization that facilitates global learning experiences. Medical, nursing, and pharmacy students were already participating in a 4-week international health-related service learning rotation through Amizade. The preexisting relationship and contractual agreement with the university provided the necessary legal framework. Amizade staff assisted in finding a physical therapist qualified and willing to host a student. The academic coordinator for clinical education at the university and Amizade liaisons determined living arrangements, schedule, clinical settings, and patient population. The selected student had expressed interest and had met all clinical education placement requirements. The academic coordinator for clinical education had ongoing electronic communications with all parties. The student demonstrated predicted attributes of cultural competence and professionalism; through the partnership with Amizade, the student was exposed to several unique interprofessional experiences. The steps used by the university faculty in developing this interprofessional, international clinical education experience through a collaborative partnership may provide guidance for other institutions.

    Radiation therapy of the intact breast is the standard therapy for preventing local recurrence of early-stage breast cancer following breast conservation surgery. To improve patient standard of care, there is a need to define a consistent and transparent treatment path for all patients that reduces significance variations in the acceptability of treatment plans. There is lack of consistency among institutions or individuals about what is considered an acceptable treatment plan: target coverage vis-à-vis dose to organs at risk (OAR). Clinical trials usually resolve these issues, as the criteria for an acceptable plan within the trial (target coverage and doses to OAR) are well defined. We developed an institutional criterion for accepting breast treatment plans in 2006 after analyzing treatment data of approximately 200 patients. The purpose of this article is to report on the dosimetric review of 623 patients treated in the last 18 months to evaluate the effectiveness of the previously developed plan acceptability criteria and any possible changes necessary to further improve patient care. The mean patient age is 61.6 years (range: 25.2 to 93.0 years). The mean breast separation for all the patients is 21.0 cm (range: 12.4 to 34.9 cm), and the mean planning target volume (PTV-eval) (breast volume for evaluation) is 884.0 cm{sup 3} (range: 73.6 to 3684.6 cm{sup 3}). Overall, 314 (50.4%) patients had the disease in the left breast and 309 (49.6%) had it in the right breast. A total of 147 (23.6%) patients were treated using the deep inspiration breath-hold (DIBH) technique. The mean normalized PTV-eval receiving at least 92% (V{sub 92%} {sub PD}) and 95% (V{sub 95%} {sub PD}) of the prescribed dose (PD) are more than 99% and 97%, respectively, for all patients. The mean normalized PTV-eval receiving at least 105% (V{sub 105%} {sub PD}) of the PD is less than 1% for all groups.

    Background For the purpose of diagnosis, psychopathology can be represented as categories of mental disorder, symptom dimensions or symptom networks. Also, psychopathology can be assessed at different levels of temporal resolution (monthly episodes, daily fluctuating symptoms, momentary fluctuating mental states). We tested the diagnostic value, in terms of prediction of treatment needs, of the combination of symptom networks and momentary assessment level. Method Fifty-seven patients with a psychotic disorder participated in an ESM study, capturing psychotic experiences, emotions and circumstances at 10 semi-random moments in the flow of daily life over a period of 6 days. Symptoms were assessed by interview with the Positive and Negative Syndrome Scale (PANSS); treatment needs were assessed using the Camberwell Assessment of Need (CAN). Results Psychotic symptoms assessed with the PANSS (Clinical Psychotic Symptoms) were strongly associated with psychotic experiences assessed with ESM (Momentary Psychotic Experiences). However, the degree to which Momentary Psychotic Experiences manifested as Clinical Psychotic Symptoms was determined by level of momentary negative affect (higher levels increasing probability of Momentary Psychotic Experiences manifesting as Clinical Psychotic Symptoms), momentary positive affect (higher levels decreasing probability of Clinical Psychotic Symptoms), greater persistence of Momentary Psychotic Experiences (persistence predicting increased probability of Clinical Psychotic Symptoms) and momentary environmental stress associated with events and activities (higher levels increasing probability of Clinical Psychotic Symptoms). Similarly, the degree to which momentary visual or auditory hallucinations manifested as Clinical Psychotic Symptoms was strongly contingent on the level of accompanying momentary paranoid delusional ideation. Momentary Psychotic Experiences were associated with CAN unmet treatment needs, over and above PANSS

    DeVylder, Jordan E; Hilimire, Matthew R

    2015-08-01

    Subthreshold psychotic experiences are common in the population and may be clinically significant. Reporting of psychotic experiences through self-report screens may be subject to threats to validity, including social desirability biases. This study examines the influence of social desirability on the reporting of psychotic experiences. College students (n = 686) completed a psychosis screen and the Marlowe-Crowne social desirability scale as part of a self-report survey battery. Associations between psychosis and social desirability were tested using logistic regression models. With the exception of auditory hallucinations, all other measures of psychotic experiences were subject to social desirability biases. Respondents who gave more socially desirable answers were less likely to report psychotic experiences. Respondent's tendency to underreport psychotic experiences should be accounted for when screening for these symptoms clinically. Findings also suggest that population figures based on self-report may underestimate the prevalence of subthreshold delusions but not hallucinations. © 2014 Wiley Publishing Asia Pty Ltd.

    Full Text Available Background: The importance of rapid and accurate cytopathological diagnosis in bronchial cancers is increasing due to advances in treatment modalities.Aims: We evaluated the diagnostic methods and cytologic subtypes of bronchial cancers to determine the diagnostic reliability of different bronchoscopic techniques.Material and methods: Retrospective data were obtained from the hospital files and pathological specimens of the patients with diagnosis of primary lung cancer from a period of 36 months. Cytological tumor typing was determined using histopathology of bronchoscopic forceps biopsy (FB, bronchial-bronchoalveolar lavage (BL, bronchial brushing (BB, transbronchial fine-needle biopsy. Computed tomography or ultrasonography guided transthoracic biopsy and surgical biopsies were used where the other interventional methods were inadequate for diagnosis.Results: A total of 124 patients were diagnosed during study period. 119 (96% of them were male. The median age was 68, ranging between 36 and 88 years. Histopathologic subtypes were determined as non-small cell carcinoma (NSCC in 104 (83.9%, squamous cell carcinoma in 64 (51.6%, adenocarcinoma in 16 (12.9%, NSCC not otherwise specified in 24 (19.3% and small cell carcinoma in 20 (16.1% patients. The combination of FB, BL and BB established the diagnosis of bronchogenic carcinoma in most of the cases (92.6%.Conclusions: Lung cancer is seen commonly in elderly male patients with smoking history and squamous cell carcinoma is the most common cytologic type. High diagnostic accuracy can be achieved by a combination of bronchoscopic FB, BB and BL procedures. Keywords: Bronchoscopy; Lung cancer; Bronchial brushing

  19. Facilitative and obstructive factors in the clinical learning environment: Experiences of pupil enrolled nurses

    2015-02-01

    Full Text Available Background: The clinical learning environment is a complex social entity that influences student learning outcomes in the clinical setting. Students can experience the clinical learning environment as being both facilitative and obstructive to their learning. The clinical environment may be a source of stress, creating feelings of fear and anxiety which in turn affect the students’ responses to learning. Equally, the environment can enhance learning if experienced positively.Objectives: This study described pupil enrolled nurses’ experiences of facilitative and obstructive factors in military and public health clinical learning settings.Method: Using a qualitative, contextual, exploratory descriptive design, three focus group interviews were conducted until data saturation was reached amongst pupil enrolled nurses in a military School of Nursing.Results: Data analysed provided evidence that acceptance by clinical staff and affordance of self-directed learning facilitated learning. Students felt safe to practise when they were supported by the clinical staff. They felt a sense of belonging when the staff showed an interest in and welcomed them. Learning was obstructed when students were met with condescending comments. Wearing of a military uniform in the public hospital and horizontal violence obstructed learning in the clinical learning environment.Conclusion: Students cannot have effective clinical preparation if the environment is not conducive to and supportive of clinical learning, The study shows that military nursing students experience unique challenges as they are trained in two professions that are hierarchical in nature. The students experienced both facilitating and obstructing factors to their learning during their clinical practice. Clinical staff should be made aware of factors which can impact on students’ learning. Policies need to be developed for supporting students in the clinical learning environment.

    This study examines the emotional experiences and perceptions of librarians embedded into clinical care teams and how those perceptions affect their training and preparation needs. Qualitative research methodologies were applied to textual data drawn from focus groups (n = 21), interviews (n = 2), and an online survey (n = 167), supplemented by quantitative survey data. Phenomenological results show librarians experience strongly affective responses to clinical rounding. Important factors include personal confidence; relationships with team members, patients, and families; and the stressful environment. Analysis of librarians' perceived educational needs indicates that training must address specialized subjects including medical knowledge, clinical culture, and institutional politics.

    2014-07-11

    There is recognition that the provision of excellence in education and training results in a skilled and competent workforce. However, the educational experiences of dental core trainees (DCT's) working in the hospital oral and maxillofacial surgery (OMFS) setting have not been previously investigated. In this paper, we examine DCT's learning experiences both 'formal' and 'non-formal' within the hospital setting of ward and clinic-based teaching. Are hospital dental core trainees receiving a meaningful educational experience? To conclude this paper, the authors recommend methods, based upon sound educational principles, to maximise the value of clinical sessions for teaching.

    Full Text Available Nursing practice includes complex reasoning and multifaceted decision making with minimal standardized guidance in how to evaluate this phenomenon among nursing students. Learning outcomes related to the clinical reasoning process among novice baccalaureate nursing students during a simulation experience were evaluated. Nursing process records were utilized to evaluate and foster the development of clinical reasoning in a high-fidelity medical-surgical simulation experience. Students were unable to describe and process pertinent patient information appropriately prior to the simulation experience. Students’ ability to identify pertinent patient cues and plan appropriate patient care improved following the simulation. The learning activity afforded a structured opportunity to identify cues, prioritize the proper course of nursing interventions, and engage in collaboration among peers. The simulation experience provides faculty insight into the students’ clinical reasoning processes, while providing students with a clear framework for successfully accomplishing learning outcomes.

    We examined whether a sexually transmitted disease (STD) clinic could reach women who had not received a Papanicolau (Pap) test in the past 3 years. We also explored staff attitudes and implementation of cervical cancer screening. Women (n = 123) aged 30 to 50 years were offered cervical cancer screening in an Indiana STD clinic. We measured effectiveness by the patients' self-reported last Pap test. We explored adoption of screening through focus groups with 34 staff members by documenting their attitudes about cervical cancer screening and screening strategy adaptation. We also documented recruitment and screening implementation. Almost half (47.9%) of participants reported a last Pap test 3 or more years previously; 30% had reported a last Pap more than 5 years ago, and 11.4% had a high-risk test outcome that required referral to colposcopy. Staff supported screening because of mission alignment and perceived patient benefit. Screening adaptations included eligibility, results provision, and follow-up. Cervical cancer screening was possible and potentially beneficial in STD clinics. Future effectiveness-implementation studies should expand to include all female patients, and should examine the degree to which adaptation of selected adoption frameworks is feasible.

    2016-11-01

    Full Text Available Background: The use of music to relieve anxiety has been examined in various studies, but the results are inconclusive. Methods: From April to October 2015, 160 patients undergoing examination of pulmonary nodules were randomly assigned to MusiCure or no music. MusiCure was administered through earplugs to ensure blinding of the staff and was played from admission to the operating theatre to the end of the bronchoscopy. Spielberger's State-Trait Anxiety Inventory (STAI was administered on admission, immediately before bronchoscopy, and on discharge. Secondary outcomes were p-cortisol, physiological variables, dosage of sedatives, movements measured by Actigraph, bronchoscopy duration, number of re-examinations, and overall perception of the sounds in the operating theatre measured by Visual analogue scale. Results: The STAI scores were similar on admission, but after a 10-min wait in the operating theatre, scores varied significantly between patients with and without music, with lower scores in the music group [median (interquartile range, IQR 35 (18 vs. 43 (25; p=0.03]. Post hoc multiple regression revealed treatment group as insignificant when adjusting for sex and baseline anxiety. However, there was a significantly more positive perception of the sounds in the operating theatre in the music group (median (IQR 8.2 (1.8 vs. 5.4 (6.8; p<0.0001 and fewer re-examinations in the music group (19.2% vs. 7.7%, p<0.032. Conclusions: Ten minutes with MusiCure does not alter anxiety when adjusting for baseline anxiety and sex. The current study indicates that this field of research has many confounders.

    Full Text Available Aims: To evaluate the diagnostic utility of virtual bronchoscopy, multiplanar reformatted images, and minimal-intensity projection in assessing airway stenoses. Settings and Design: It was a prospective study involving 150 patients with symptoms of major airway disease. Materials and Methods: Fifty-six patients were selected for analysis based on the detection of major airway lesions on fiber-optic bronchoscopy (FB or routine axial images. Comparisons were made between axial images, virtual bronchoscopy (VB, minimal-intensity projection (minIP, and multiplanar reformatted (MPR images using FB as the gold standard. Lesions were evaluated in terms of degree of airway narrowing, distance from carina, length of the narrowed segment and visualization of airway distal to the lesion. Results: MPR images had the highest degree of agreement with FB (Κ = 0.76 in the depiction of degree of narrowing. minIP had the least degree of agreement with FB (Κ = 0.51 in this regard. The distal visualization was best on MPR images (84.2%, followed by axial images (80.7%, whereas FB could visualize the lesions only in 45.4% of the cases. VB had the best agreement with FB in assessing the segment length (Κ = 0.62. Overall there were no statistically significant differences in the measurement of the distance from the carina in the axial, minIP, and MPR images. MPR images had the highest overall degree of confidence, namely, 70.17% (n = 40. Conclusion: Three-dimensional reconstruction techniques were found to improve lesion evaluation compared with axial images alone. The technique of MPR images was the most useful for lesion evaluation and provided additional information useful for surgical and airway interventions in tracheobronchial stenosis. minIP was useful in the overall depiction of airway anatomy.

    Nursing faculty teaching medical students a module in clinical skills is a relatively new trend. Collaboration in education among medical and nursing professions can improve students’ performance in clinical skills and consequently positively impact the quality of care delivery. In 2011, the Faculty of Medicine in collaboration with the Faculty of Health Sciences at the University of Balamand, Beirut, Lebanon, launched a module in clinical skills as part of clinical skills teaching to first-year medical students. The module is prepared and delivered by nursing faculty in a laboratory setting. It consists of informative lectures as well as hands-on clinical practice. The clinical competencies taught are hand-washing, medication administration, intravenous initiation and removal, and nasogastric tube insertion and removal. Around sixty-five medical students attend this module every year. A Likert scale-based questionnaire is used to evaluate their experience. Medical students agree that the module provides adequate opportunities to enhance clinical skills and knowledge and favor cross-professional education between nursing and medical disciplines. Most of the respondents report that this experience prepares them better for clinical rotations while increasing their confidence and decreasing anxiety level. Medical students highly appreciate the nursing faculties’ expertise and perceive them as knowledgeable and resourceful. Nursing faculty participating in medical students’ skills teaching is well perceived, has a positive impact, and shows nurses are proficient teachers to medical students. Cross professional education is an attractive model when it comes to teaching clinical skills in medical school. PMID:25419165

    There exists a need for innovative thinking to identify new clinical placement opportunities for nursing students. Recovery-based clinical placements for mental health nurse students remain unique and require investigation. To examine the learning experience of Bachelor of Nursing students who undertook an innovative mental health clinical placement known as Recovery Camp. This study incorporated qualitative analysis of written reflections. Using Braun and Clarke's (2006) six phases of thematic analysis the corpus of student reflections were reviewed by three members of the research team independent to each other. Four themes emerged. The theme of Pre-placement Expectations incorporates participant foci on pre-conceptions of Recovery Camp. The theme of Student Learning incorporates the ways in which participants recognised the experience of Recovery Camp influenced learning. Reflections themed under the title Placement Setting include discussion of the Recovery Camp as a clinical placement. The theme of Future Practice incorporates students' reflections on how they plan to practice as nurses as a result the learning experiences of Recovery Camp. An immersive clinical placement such as Recovery Camp can influence students' perceptions of people with mental illness, have a positive impact on student learning and influence students' decisions about future practice. The learning experience of nursing students whom attend unique, recovery-orientated clinical placements can be both positive and educative. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Clinical experience and exposure to real patients are required elements of nursing education. Trainees in nursing are expected to be prepared adequately for the hard-working environment, increasing patient complexity, and higher-level competencies. This study investigates differences between nursing interns and clinical faculty on actual and perceived importance of educational preparation and development of clinical competencies, focusing on the nursing curriculum and transition to practice. A convenient sampling technique with a mixed-methods design was used to collect quantitative and qualitative data, by surveying and interviewing nursing interns and faculty members from King Abdul-Aziz University in Saudi Arabia; data collection occurred in December 2015. The survey (23 items) and focused interviews measured perceptions of clinical instruction and experience. Descriptive statistics and t-tests were used to analyze differences in mean ratings between actual and perceived importance. Themes collected from narrative interview data were summarized. Significant differences were found between nursing interns (n = 46) and faculty (n = 29) perceptions of actual clinical teaching and experiences and its importance including the clinical teaching and the development of clinical competence, p interns rated actual experiences of knowledge base and skills significantly lower than faculty perceptions, p = .001. Narrative data provided in-depth information on factors contributing and hindering the learning and teaching environment. Findings from this study call for clinical instruction and experiences to take a step further to meet current practice standards and to improve patient safety in the health professions education of nurses.

    2014-03-01

    To consider the experiences of final-year physiotherapy students who have experienced workplace bullying on a clinical internship. Qualitative methodology using individual semi-structured interviews. A university in the Midlands region of the UK. Eight undergraduate physiotherapy students who had experienced one incident of bullying on a clinical internship. Thematic analysis of semi-structured interviews. Four main themes were identified: (1) external and situational influences of bullying; (2) students' reactions to the experience of bullying; (3) inability to reveal the experience; and (4) overcoming problems. Bullying had a range of adverse effects on the students, with many expressing self-doubt in their competence and viewing their supervisor as unapproachable and unsupportive. Five students were not initially able to recognise the experience as bullying. In addition, students did not feel able to report the experience and use the support mechanisms in place. This may have been a result of having concerns that the problem would escalate if they reported the experience and, as a consequence, have a negative effect on their grade. Students were keen to offer a range of strategies for clinical practice in order to prevent bullying for future generations of students. Students' health, security and confidence in their ability as a physiotherapist can be at great risk from bullying. Steps are needed to ensure that students are better protected from bullying, and feel more able to address bullying behaviour during clinical internships.

    2016-07-16

    Health professional education programs attract students from around the world and clinical supervisors frequently report that international students find learning in clinical placement contexts particularly challenging. In existing literature clinical supervisors, who support international students on placement have identified concerns about their communication and interactions within clinical environments. However, clinical supervisors' perspectives about their experiences with international students on placement and the strategies they utilise to facilitate international student learning have not been described. As a result we have little insight into the nature of these concerns and what clinical supervisors do to support international students' competency development. Five focus group interviews were conducted with twenty Speech-Language Pathology clinical supervisors, recruited from 2 Australian universities. Interview data were analysed thematically. Themes identified were interpreted using cognitive load and sociocultural learning theories to enhance understanding of the findings. Four themes were identified: 'Complex teaching and learning relationships', 'Conceptions of students as learners'; Student communication skills for professional practice', and 'Positive mutual learning relationships'. Findings indicated that clinical supervisors felt positive about supporting international students in clinical placements and experienced mutual learning benefits. However, they also identified factors inherent to international students and the placement environment that added to workload, and made facilitating student learning complex. Clinical supervisors described strategies they used to support international students' cultural adjustment and learning, but communication skills were reported to be difficult to facilitate within the constraints of placements. Future research should address the urgent need to develop and test strategies for improving international

    Physical therapists strive to integrate research into daily practice. The tablet computer is a potentially transformational tool for accessing information within the clinical practice environment. The purpose of this study was to measure and describe patterns of tablet computer use among physical therapy students during clinical rotation experiences. Doctor of physical therapy students (n = 13 users) tracked their use of tablet computers (iPad), loaded with commercially available apps, during 16 clinical experiences (6-16 weeks in duration). The tablets were used on 70% of 691 clinic days, averaging 1.3 uses per day. Information seeking represented 48% of uses; 33% of those were foreground searches for research articles and syntheses and 66% were for background medical information. Other common uses included patient education (19%), medical record documentation (13%), and professional communication (9%). The most frequently used app was Safari, the preloaded web browser (representing 281 [36.5%] incidents of use). Users accessed 56 total apps to support clinical practice. Physical therapy students successfully integrated use of a tablet computer into their clinical experiences including regular activities of information seeking. Our findings suggest that the tablet computer represents a potentially transformational tool for promoting knowledge translation in the clinical practice environment.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, http://links.lww.com/JNPT/A127).

    This paper explores and contrasts undergraduate medical and nursing students' experiences of the clinical learning environment. Using a sociocultural perspective of learning and an interpretative approach, 15 in-depth interviews with medical and nursing students were analysed with content analysis. Students' experiences are described using a framework of 'before', 'during' and 'after' clinical placements. Three major themes emerged from the analysis, contrasting the medical and nursing students' experiences of the clinical learning environment: (1) expectations of the placement; (2) relationship with the supervisor; and (3) focus of learning. The findings offer an increased understanding of how medical and nursing students learn in the clinical setting; they also show that the clinical learning environment contributes to the socialisation process of students not only into their future profession, but also into their role as learners. Differences between the two professions should be taken into consideration when designing interprofessional learning activities. Also, the findings can be used as a tool for clinical supervisors in the reflection on how student learning in the clinical learning environment can be improved.

    To investigate the incidence of achalasia in Algeria and to determine its clinical and para-clinical profile. To evaluate the impact of continuing medical education (CME) on the incidence of this disease. From 1990 to 2014, 1256 patients with achalasia were enrolled in this prospective study. A campaign of CME on diagnosis involving different regions of the country was conducted between 1999 and 2003. Annual incidence and prevalence were calculated by relating the number of diagnosed cases to 10(5) inhabitants. Each patient completed a standardized questionnaire, and underwent upper endoscopy, barium swallow and esophageal manometry. We systematically looked for Allgrove syndrome and familial achalasia. The mean annual incidence raised from 0.04 (95%CI: 0.028-0.052) during the 1990s to 0.27/10(5) inhabitants/year (95%CI: 0.215-0.321) during the 2000s. The incidence of the disease was two and half times higher in the north and the center compared to the south of the country. One-hundred-and-twenty-nine (10%) were children and 97 (7.7%) had Allgrove syndrome. Familial achalasia was noted in 18 different families. Patients had dysphagia (99%), regurgitation (83%), chest pain (51%), heartburn 24.5% and weight loss (70%). The lower esophageal sphincter was hypertensive in 53% and hypotensive in 0.6%. The mean incidence of achalasia in Algeria is at least 0.27/10(5) inhabitants. A good impact on the incidence of CME was noted. A gradient of incidence between different regions of the country was found. This variability is probably related to genetic and environmental factors. The discovery of an infantile achalasia must lead to looking for Allgrove syndrome and similar cases in the family.

    Full Text Available Objective: To analyze the clinical features of lung cancer diagnosed by bronchoscopy. Methods: The clinical features of 2168 patients with lung cancer diagnosed by bronchoscopy were retrospectively analyzed, including gender, age, pathological type, diseased region, manifestations under bronchoscopy and methods of drawing materials. Results: The ratio of male/female was 4.8:1 and the peak onset age was 60 - 69 years old. The major pathological type was squamous cell carcinoma (44.5%, then adenocarcinoma (25.9% and small cell lung cancer (18.3%. The incidence of squamous cell carcinoma was the highest in males (50.6%, while that of adenocarcinoma in females (56.2%. The positive diagnostic rates of forceps biopsy, brush biopsy, bronchial alveolar lavage and transbronchial needle aspiration were 81.6%, 49.4%, 18.2% and 62.6%, respectively, whereas that of biopsy combined with brush biopsy came up to 89.0%. Conclusion: Bronchoscopy is an important method in diagnosis of lung cancer. Different ages and genders of patients with lung cancer have different onset, and the distribution of pathological types is diverse. Attaching more importance to bronchoscopy and improving biopsy technique can significantly improve the diagnostic rate and provide reliable evidences for clinical treatment.

The major pathological type was squamous cell carcinoma (44.5%), then adenocarcinoma (25.9%) and small cell lung cancer (18.3%). The incidence of squamous cell carcinoma was the highest in males (50.6%), while that of adenocarcinoma in females (56.2%). The positive diagnostic rates of forceps biopsy, brush biopsy, bronchial alveolar lavage and transbronchial needle aspiration were 81.6%, 49.4%, 18.2% and 62.6%, respectively, whereas that of biopsy combined with brush biopsy came up to 89.0%. Conclusion: Bronchoscopy is an important method in diagnosis of lung cancer. Different ages and genders of patients with lung cancer have different onset, and the distribution of pathological types is diverse. Attaching more importance to bronchoscopy and improving biopsy technique can signiifcantly improve the diagnostic rate and provide reliable evidences for clinical treatment.

    Background The use of near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) for sentinel lymph node (SN) mapping has been investigated in lung cancer; however, this has not been fully adapted for minimally invasive surgery (MIS). The aim of our study was to develop a minimally invasive SN mapping integrating pre-operative electro-magnetic navigational bronchoscopy (ENB)-guided transbronchial ICG injection and intraoperative NIR thoracoscopic imaging. Methods A NIR thoracoscope was used to visualize ICG fluorescence. ICG solutions in a 96-well plate and ex vivo porcine lungs were examined to optimize ICG concentrations and injection volumes. Transbronchial ICG injection (n=4) was assessed in comparison to a traditional transpleural approach (n=3), where after thoracotomy an ICG solution (100μL at 100μg/mL) was injected into the porcine right upper lobe for SN identification. For further translation into clinical use, transbronchial ICG injection prior to thoracotomy followed by NIR thoracoscopic imaging was validated (n=3). ENB was used for accurate targeting in two pigs with a pseudo-tumor. Results The ICG fluorescence at 10 μg/mL was the brightest among various concentrations, unchanged by the distance between the thoracoscope and ICG solutions. Injected ICG of no more than 500μL showed a localized fluorescence area. All 7 pigs showed a bright paratracheal lymph node within 15 minutes post-injection, with persistent fluorescence for 60 minutes. The antecedent transbronchial ICG injection succeeded in SN identification in all 3 cases at the first thoracoscopic inspection within 20 minutes post-injection. The ENB system allowed accurate ICG injection surrounding the pseudo-tumors. Conclusions ENB-guided ICG injection followed by NIR thoracoscopy was technically feasible for SN mapping in the porcine lung. This promising platform may be translated into human clinical trials and is suited for MIS. PMID:25993006

    The clinical experience and preferred learning style of U.S. Air Force flight nurses and aeromedical evacuation technicians are unknown. Using a cross-sectional survey design, we gathered data regarding the clinical experience, level of comfort providing clinical care, and preferred learning style of 77 active duty (AD), Air Force Reserve (AFR), and Air National Guard (ANG) nurses enrolled in the U.S. Air Force School of Aerospace Medicine Flight Nurse course, and 121 AD, AFR, and ANG medical technicians enrolled in the Aeromedical Evacuation Technician course. Nurses and medical technicians reported 7.6 ± 5.5 and 3.9 ± 4.5 yr of experience, respectively. AD, AFR, and ANG nurses had comparable years of experience: 5.8 ± 3.2, 8.3 ± 6.6, and 7.9 ± 4.2 yr, respectively; however, AD medical technicians had more years of experience (5.6 ± 4.4 yr) than AFR (3.1 ± 4.8 yr) and ANG (1.9 ± 2.8 yr) medical technicians. Both nurses and medical technicians reported infrequently caring for patients with various disease processes and managing equipment or devices that they will routinely encounter when transporting patients as an aeromedical evacuation clinician. Nurses and medical technicians preferred a kinesthetic learning style or a multimodal learning style that included kinesthetic learning. Nearly all (99%) nurses and 97% of medical technicians identified simulation as their preferred teaching method. These findings confirm faculty concerns regarding the clinical experience of flight nurse and aerospace evacuation technician students.De Jong MJ, Dukes SF, Dufour KM, Mortimer DL.

    Approximately 8% of couples attempting to conceive are infertile and male infertility accounts for approximately 50% of infertility among couples. Up to 25% of males with non-obstructive infertility have chromosomal abnormalities and/or microdeletions of the long arm of the Y-chromosome. These are detected by conventional chromosome and Y-microdeletion analysis. In this study, we reviewed the results of testing performed in the Mayo Clinic Cytogenetics and Molecular Genetics Laboratories and compared our findings with previously published reports. This study includes 2,242 chromosome studies from males ≥18 years of age referred for infertility between 1989 and 2000 and 2,749 Y-deletion molecular studies performed between 2002 and 2009. 14.3% of infertile males tested by karyotyping had abnormalities identified. These include: (258) 47,XXY and variants consistent with Klinefelter syndrome, (3) combined 47,XXY and balanced autosomal rearrangements, (9) 47,XYY, (9) Y-deletions, (7) 46,XX males, (32) balanced rearrangements, and (1) unbalanced rearrangement. 3.6% of males tested for Y-microdeletion analysis had abnormalities identified, 90% of which included a deletion of the AZFc region. This study highlights the need of males suffering from non-obstructive infertility to have laboratory genetic testing performed. An abnormal finding can have significant consequences to assisted reproductive techniques and fertility treatment, and provide a firm diagnosis to couples with longstanding infertility.

Collaboration in education among medical and nursing professions can improve students' performance in clinical skills and consequently positively impact the quality of care delivery. In 2011, the Faculty of Medicine in collaboration with the Faculty of Health Sciences at the University of Balamand, Beirut, Lebanon, launched a module in clinical skills as part of clinical skills teaching to first-year medical students. The module is prepared and delivered by nursing faculty in a laboratory setting. It consists of informative lectures as well as hands-on clinical practice. The clinical competencies taught are hand-washing, medication administration, intravenous initiation and removal, and nasogastric tube insertion and removal. Around sixty-five medical students attend this module every year. A Likert scale-based questionnaire is used to evaluate their experience. Medical students agree that the module provides adequate opportunities to enhance clinical skills and knowledge and favor cross-professional education between nursing and medical disciplines. Most of the respondents report that this experience prepares them better for clinical rotations while increasing their confidence and decreasing anxiety level. Medical students highly appreciate the nursing faculties' expertise and perceive them as knowledgeable and resourceful. Nursing faculty participating in medical students' skills teaching is well perceived, has a positive impact, and shows nurses are proficient teachers to medical students. Cross professional education is an attractive model when it comes to teaching clinical skills in

    To compare safety and efficacy of percutaneous vertebroplasty (PVP) when treating up to three vertebrae or more than three vertebrae per session. We prospectively compared two groups of patients with symptomatic vertebral fractures who had no significant response to conservative therapy. Pathologic substrate included osteoporosis (n = 77), metastasis (n = 24), multiple myeloma (n = 13), hemangioma (n = 15), and lymphoma (n = 1). Group A patients (n = 94) underwent PVP of up to three treated vertebrae (n = 188). Group B patients (n = 36) underwent PVP with more than three treated vertebrae per session (n = 220). Decreased pain and improved mobility were recorded the day after surgery and at 12 and 24 months after surgery per clinical evaluation and the use of numeric visual scales (NVS): the Greek Brief Pain Inventory, a linear analogue self-assessment questionnaire, and a World Health Organization questionnaire. Group A presented with a mean pain score of 7.9 {+-} 1.1 NVS units before PVP, which decreased to 2.1 {+-} 1.6, 2.0 {+-} 1.5 and 2.0 {+-} 1.5 NVS units the day after surgery and at 12 and 24 months after surgery, respectively. Group B presented with a mean pain score of 8.1 {+-} 1.3 NVS units before PVP, which decreased to 2.2 {+-} 1.3, 2.0 {+-} 1.5, and 2.1 {+-} 1.6 NVS units the day after surgery and at 12 and 24 months after surgery, respectively. Overall pain decrease and mobility improvement throughout the follow-up period presented no statistical significance neither between the two groups nor between different underlying aetiology. Reported cement leakages presented no statistical significance between the two groups (p = 0.365). PVP is an efficient and safe technique for symptomatic vertebral fractures independently of the vertebrae number treated per session.

    Service-learning involvement can be a useful adjunct to a traditional educational experience and can provide clinical exposure in mental health practice settings for undergraduate nursing students. Education and practice collaboratives in community settings benefit community partners through the service provided by students to the respective community organizations. Benefits to students are obvious through greater exposure to community agencies, avenues to meet academic clinical course objectives, and incentives for their critical and independent thinking. An overview of the process of engaging students in community engagement opportunities that provide clinical hours in an undergraduate mental health course is presented.

    Objective The experience sampling method (ESM) is a structured diary technique to appraise subjective experiences in daily life. It is applied in psychiatric patients, as well as in patients with somatic illness. Despite the potential of ESM assessment, the improved logistics and its increased administration in research, its use in clinical trials remains limited. This paper introduces ESM for clinical trials in psychiatry and beyond. Methods ESM is an ecologically valid method that yields a comprehensive view of an individual's daily life. It allows the assessment of various constructs (eg, quality of life, psychopathology) and psychological mechanisms (eg, stress-sensitivity, coping). These constructs are difficult to assess using cross-sectional questionnaires. ESM can be applied in treatment monitoring, as an ecological momentary intervention, in clinical trials, or in single case clinical trials. Technological advances (eg, smartphone applications) make its implementation easier. Results Advantages of ESM are highlighted and disadvantages are discussed. Furthermore, the ecological nature of ESM data and its consequences are explored, including the potential pitfalls of ambiguously formulated research questions and the specificities of ESM in statistical analyses. The last section focuses on ESM in relation to clinical trials and discusses its future use in optimising clinical decision-making. Conclusions ESM can be a valuable asset in clinical trial research and should be used more often to study the benefits of treatment in psychiatry and somatic health. PMID:27443678

    Structured clinical documentation is an important component of electronic health records (EHRs) and plays an important role in clinical care, administrative functions, and research activities. Clinical data elements serve as basic building blocks for composing the templates used for generating clinical documents (such as notes and forms). We present our experience in creating and maintaining data elements for three different EHRs (one home-grown and two commercial systems) across different clinical settings, using flowsheet data elements as examples in our case studies. We identified basic but important challenges (including naming convention, links to standard terminologies, and versioning and change management) and possible solutions to address them. We also discussed more complicated challenges regarding governance, documentation vs. structured data capture, pre-coordination vs. post-coordination, reference information models, as well as monitoring, communication and training.

    Full Text Available The study focused on the clinical learning experiences of Pupil Enrolled Nurses (PENs within the military health service. The purpose of the research was to explore and describe the learning experiences of PENs within the Military health clinical learning environment. An explorative, descriptive, contextual design which is qualitative in nature was used to guide the study. The military as a training institution prides itself on preparing nurses both as soldiers and nurses, this could be both challenging and exasperating for students, as the scopes are diverse. Being notably very hierarchical, the military’s rules constantly take precedence over nursing rules. For the duration of nursing training, students are allocated in the clinical learning area to acquire competencies such as problem solving, cognitive and psychomotor skills (Kuiper & Pesut 2003:383. Students learn how to merge theory and practice and apply theories in the practical sense. This is however, not done in isolation from the military codes, as they are intertwined. Attendance of military parades and drills are incorporated during this phase. This could create missed opportunities from the clinical learning as students are expected to leave the clinical setting for this purpose. Three focus group sessions were conducted and the experiences of the students, as narrated by themselves, yielded valuable insights. The researcher wrote field notes and assisted with the management of the audio tapes for easy retrieval of information. Data was analysed by the researcher, independent of the cocoder. Two themes relating to the PENs’ learning experiences emerged from the data analysed: (1 facilitators of clinical learning, (2 and barriers to clinical learning. The findings obtained depicted those factors which facilitated and obstructed student learning. These findings made it possible for the researcher to make recommendations concerning positive interventions which could be taken to

    Belongingness has been identified both as a fundamental human need and as a prerequisite for nursing students' clinical learning. Belongingness has also been associated with students' academic achievement, retention, self-esteem, self-directed learning, and self-efficacy. The Belongingness Scale-Clinical Placement Experience is a valid and reliable measure of nursing students' belongingness scores; however, a Persian version of this scale is not currently available. This study aimed to translate the Belongingness Scale-Clinical Placement Experience into Persian, to evaluate its psychometric properties, and to measure the belongingness experiences of Iranian nursing students. Following translation and initial validity and reliability testing of the scale, 300 nursing students from three universities in Iran completed the survey. Further psychometric testing was undertaken followed by analysis of descriptive statistics. Based on the results of confirmatory factor analysis two items were removed from the scale. The mean score of Persian version of the Belongingness Scale-Clinical Placement Experience was 3.21 (0.57). The whole scale had a high internal consistency (Cronbach's alpha=0.92). The alpha coefficients of the subscales of "self-esteem", "connectedness", and "efficacy" were 0.85, 0.86, and 0.80 respectively. Similar to previous versions of the Belongingness Scale-Clinical Placement Experience, the Persian version demonstrated strong psychometric properties with strong validity and reliability, indicating its utility and appropriateness when measuring Iranian nursing students' belongingness experiences. Further testing with other cohorts would strengthen these results. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2016-03-01

    The aim of this study was to ascertain which assumptions dental students recalled feeling prior to beginning community-based clinical experiences and whether those assumptions were fulfilled or challenged. All fourth-year students at the University of Iowa College of Dentistry & Dental Clinics participate in community-based clinical experiences. At the completion of their rotations, they write a guided reflection paper detailing the assumptions they had prior to beginning their rotations and assessing the accuracy of their assumptions. For this qualitative descriptive study, the 218 papers from three classes (2011-13) were analyzed for common themes. The results showed that the students had a variety of assumptions about their rotations. They were apprehensive about working with challenging patients, performing procedures for which they had minimal experience, and working too slowly. In contrast, they looked forward to improving their clinical and patient management skills and knowledge. Other assumptions involved the site (e.g., the equipment/facility would be outdated; protocols/procedures would be similar to the dental school's). Upon reflection, students reported experiences that both fulfilled and challenged their assumptions. Some continued to feel apprehensive about treating certain patient populations, while others found it easier than anticipated. Students were able to treat multiple patients per day, which led to increased speed and patient management skills. However, some reported challenges with time management. Similarly, students were surprised to discover some clinics were new/updated although some had limited instruments and materials. Based on this study's findings about students' recalled assumptions and reflective experiences, educators should consider assessing and addressing their students' assumptions prior to beginning community-based dental education experiences.

    Full Text Available Few data are available on how women manage recurring bacterial vaginosis (BV and their experiences of the clinical care of this condition. This study aimed to explore women's recurrent BV management approaches and clinical care experiences, with a view to informing and improving the clinical management of BV.A descriptive, social constructionist approach was chosen as the framework for the study. Thirty-five women of varying sexual orientation who had experienced recurrent BV in the past 5 years took part in semi-structured interviews.The majority of women reported frustration and dissatisfaction with current treatment regimens and low levels of satisfaction with the clinical management of BV. Overall, women disliked taking antibiotics regularly, commonly experienced adverse side effects from treatment and felt frustrated at having symptoms recur quite quickly after treatment. Issues in clinical care included inconsistency in advice, misdiagnosis and inappropriate diagnostic approaches and insensitive or dismissive attitudes. Women were more inclined to report positive clinical experiences with sexual health physicians than primary care providers. Women's frustrations led most to try their own self-help remedies and lifestyle modifications in an attempt to treat symptoms and prevent recurrences, including well-known risk practices such as douching.In the face of considerable uncertainty about the cause of BV, high rates of recurrence, unacceptable treatment options and often insensitive and inconsistent clinical management, women are trying their own self-help remedies and lifestyle modifications to prevent recurrences, often with little effect. Clinical management of BV could be improved through the use of standardised diagnostic approaches, increased sensitivity and understanding of the impact of BV, and the provision of evidence based advice about known BV related risk factors.

The majority of women reported frustration and dissatisfaction with current treatment regimens and low levels of satisfaction with the clinical management of BV. Overall, women disliked taking antibiotics regularly, commonly experienced adverse side effects from treatment and felt frustrated at having symptoms recur quite quickly after treatment. Issues in clinical care included inconsistency in advice, misdiagnosis and inappropriate diagnostic approaches and insensitive or dismissive attitudes. Women were more inclined to report positive clinical experiences with sexual health physicians than primary care providers. Women's frustrations led most to try their own self-help remedies and lifestyle modifications in an attempt to treat symptoms and prevent recurrences, including well-known risk practices such as douching. In the face of considerable uncertainty about the cause of BV, high rates of recurrence, unacceptable treatment options and often insensitive and inconsistent clinical management, women are trying their own self-help remedies and lifestyle modifications to prevent recurrences, often with little effect. Clinical management of BV could be improved through the use of standardised diagnostic approaches, increased sensitivity and understanding of the impact of BV, and the provision of evidence based advice about known BV related risk factors.

    This study sought to better understand and improve influenza vaccination in low-income populations regardless of their health insurance/immigration status. It assessed client satisfaction and experiences with services provided at community-based "flu outreach" clinics in South Los Angeles. The clinics represent a community-public agency partnership-a model of vaccine delivery that was relatively novel to the region. During 2011-2012, a self-administered questionnaire was distributed to clients of the local health department's 39 flu outreach clinics in South Los Angeles. The study utilized a 10-item satisfaction scale and survey questions that gauged client history and experiences with present and prior vaccinations. Of 4,497 adults who were eligible, 3,860 completed the survey (participation rate = 86%). More than 90% were satisfied with their experiences at the clinics. Younger adults were significantly more likely than adults aged 65+ to report not having been vaccinated in the previous year (p Los Angeles suggests that this model for vaccine delivery could lead to meaningful client experience of care.

    Quality clinical placement experiences have been associated with nurses' workplace social capital. Social capital is broadly understood as the social organisation of trust, norms and networks that benefit society. Building social capital in the workplace may benefit experiences of staff and students. The aim of this study was to assess the impact of building workplace social capital on student nurse perceptions of clinical learning experiences. A quality improvement process was measured through repeated student surveys. First, second, third year students (n = 1176) from three universities completed a validated Student Clinical Learning Culture Survey (SCLCS) following their placement, at the commencement of quality improvement initiatives and five years later. The SCLCS measured students' perceptions of social affiliation, their motivation, satisfaction and dissatisfaction with clinical contexts. The first year of systematic changes focused on increasing student numbers along with improving communication, trust and knowledge sharing, antecedents to workplace social capital. No change was evident after the first year. Six years after commencement of building workplace social capital differences across all subscales, except dissatisfaction, were significant (p social capital that enhances student placement experiences.

    2008-01-01

    Educating future registered nurses for social justice is an urgent, yet complex undertaking in undergraduate education. Although the need for social justice education is often highlighted, few articles describe practical teaching strategies for ensuring that undertaking. The purpose of this article is to illustrate how a curricular focus on social justice framed and supported the development of a clinical evaluation tool for undergraduate community health clinical experiences. First, social justice is defined and its relationship to baccalaureate nursing education explained. Then a description is provided of how social justice was highlighted in the vision, curriculum, and community health clinical evaluation tool of a College of Nursing. The article subsequently showcases the content and evaluation of students' journal entries about social justice. The development of the social justice component presented in this article may be useful to nurse educators striving to match theory and practice in the evaluation of social justice in students' community health experience.

    2015-01-01

    For second year medical students, we redesigned an original laboratory experiment and developed a combined research-teaching clinical biochemistry experiment. Using an established diabetic rat model to detect blood glucose and triglycerides, the students participate in the entire experimental process, which is not normally experienced during a standard clinical biochemistry exercise. The students are not only exposed to techniques and equipment but are also inspired to think more about the biochemical mechanisms of diseases. When linked with lecture topics about the metabolism of carbohydrates and lipids, the students obtain a better understanding of the relevance of abnormal metabolism in relation to diseases. Such understanding provides a solid foundation for the medical students' future research and for other clinical applications.

    2015-04-01

    The purpose of this study was to gain understanding of Norwegian students' experience of learning in clinical placement in Bangladesh without formal one-to-one supervision, by a personal mentor in the ward. Using focus group interviews with bachelor nursing students we explored the significance of 'communities of practice' in nursing practicum abroad, socialization and knowledge transfer. Seven third year bachelor nursing students enrolled in a clinical placement programme in Bangladesh participated in focus group interviews prior to their departure to Bangladesh, during their stay in Bangladesh and after their return to Norway. The Students' marginality and 'peripheral participation' triggered insight and reflection. The challenging but advantageous position of the peripheral students was heightened further due to the lack of one-to-one supervision in the clinic. Their previous experience with problem based learning and group learning was an asset that made them more resilient and helped them to cope.

    Although telemonitoring is increasingly used in heart failure care, data on expectations, experiences, and organizational implications concerning telemonitoring are rarely addressed, and the optimal profile of patients who can benefit from telemonitoring has yet to be defined. To assess the actual status of use of telemonitoring and to describe the expectations, experiences, and organizational aspects involved in working with telemonitoring in heart failure in the Netherlands. In collaboration with the Netherlands Organization for Applied Scientific Research (TNO), a 19-item survey was sent to all outpatient heart failure clinics in the Netherlands, addressed to cardiologists and heart failure nurses working in the clinics. Of the 109 heart failure clinics who received a survey, 86 clinics responded (79%). In total, 31 out of 86 (36%) heart failure clinics were using telemonitoring and 12 heart failure clinics (14%) planned to use telemonitoring within one year. The number of heart failure patients receiving telemonitoring generally varied between 10 and 50; although in two clinics more than 75 patients used telemonitoring. The main goals for using telemonitoring are "monitoring physical condition", "monitoring signs of deterioration" (n=39, 91%), "monitoring treatment" (n=32, 74%), "adjusting medication" (n=24, 56%), and "educating patients" (n=33, 77%). Most patients using telemonitoring were in the New York Heart Association (NYHA) functional classes II (n=19, 61%) and III (n=27, 87%) and were offered the use of the telemonitoring system "as long as needed" or without a time limit. However, the expectations of the use of telemonitoring were not met after implementation. Eight of the 11 items about expectations versus experiences were significantly decreased (Ptelemonitoring in their work, in particular with respect to "keeping up with current development" (before 7.2, after 6.8, P=.15), "being innovative" (before 7.0, after 6.1, P=.003), and "better guideline

    The psychological and social sciences literature is replete with assertions that human beings are fundamentally and pervasively motivated by the need to belong. This paper reports on some of the findings from the qualitative phase of a mixed-method, multi-site study that explored nursing students' experience of belongingness while on clinical placements. Students from Australia and the United Kingdom were interviewed to identify factors that impact upon and are consequences of belongingness. A montage of participants' stories is used to illustrate some of the key features of clinical workplaces that are conducive to the development of belongingness. Contextual factors and interpersonal dynamics were seen to have a significant bearing on students' experiences. Clinical leaders/managers who were welcoming, accepting and supportive, and nursing staff who were inclusive and encouraging, facilitated students' perception of being valued and respected as members of the nursing team. Additionally, the provision of consistent, quality mentorship was identified as important to students' feelings of connectedness and fit. The experience of belongingness, in turn, enhanced students' potential for learning and influenced their future career decisions. Alternatively, alienation resulted from unreceptive and unwelcoming clinical environments and from the dissonance created when students' personal and professional values did not articulate with those evident in practice environments. Consequently, distress, detachment and disengagement occurred and students' capacity and motivation for learning was negatively impacted.

    Background The quality of in-hospital resuscitation is poor and may be affected by the clinical experience and cardiopulmonary resuscitation (CPR) training. This study aimed to investigate the clinical experience, self-perceived skills, CPR training and knowledge of the guidelines on when to abandon resuscitation among physicians of cardiac arrest teams. Methods We performed a nationwide cross-sectional study in Denmark. Telephone interviews were conducted with physicians in the cardiac arrest teams in public somatic hospitals using a structured questionnaire. Results In total, 93 physicians (53% male) from 45 hospitals participated in the study. Median age was 34 (interquartile range: 30–39) years. Respondents were medical students working as locum physicians (5%), physicians in training (79%) and consultants (16%), and the median postgraduate clinical experience was 48 (19–87) months. Most respondents (92%) felt confident in treating a cardiac arrest, while fewer respondents felt confident in performing intubation (41%) and focused cardiac ultrasound (39%) during cardiac arrest. Median time since last CPR training was 4 (2–10) months, and 48% had attended a European Resuscitation Council (ERC) Advanced Life Support course. The majority (84%) felt confident in terminating resuscitation; however, only 9% were able to state the ERC guidelines on when to abandon resuscitation. Conclusion Physicians of Danish cardiac arrest teams are often inexperienced and do not feel competent performing important clinical skills during resuscitation. Less than half have attended an ERC Advanced Life Support course, and only very few physicians know the ERC guidelines on when to abandon resuscitation.

    A primary focus in nursing education is to provide students with a diverse range of clinical experiences. Historically, the collection and assessment of data from students' clinical experiences have been paper-and-pencil tasks that are arduous for both students and nursing faculty. The volume of collected information also has made it difficult to produce ad hoc statistical reports without additional intensive manual labor. To facilitate recording and analysis of these data, the Nursing and Computer Science Departments at Indiana University-Purdue University Fort Wayne have collaborated to create a Web application: Essential Clinical Behaviors. The use of the Web-accessible database represents a major change in nursing education by alteration of format used by students to record their clinical experiences in nursing courses. The application was designed to enhance nursing students' learning and to assist faculty in making student assignments, evaluating student progress, and supporting curriculum decisions. This report discusses the rationale for the development of the Web application, a description of its data entry and reporting mechanisms, an overview of the system architecture, its use in the nursing curriculum, and planned enhancements.

    2012-12-01

    In this study, patients' experiences of a nurse-led rheumatology clinic for those undergoing biological therapy are discussed. The study had an explorative design, based on a qualitative content analysis with an inductive approach. Strategic sampling was used in order to achieve variations in experiences of a nurse-led clinic. Interviews were conducted with 20 participants, and the analysis resulted in the theme "the nurse-led rheumatology clinic provided added value to patient care". The participants' experiences of the encounter with the nurse led to a sense of security (due to competence and accessibility), familiarity (due to confirmation and sensitivity), and participation (due to exchange of information and involvement). Replacing every second visit to a rheumatologist with one to a nurse added value to the rheumatology care, making it more complete. Nurses and rheumatologists complemented each other, as they approached patients from different perspectives. This study suggests that a nurse-led rheumatology clinic adds value to the quality of care for patients in rheumatology units.

    Background and Aim. Reflection is known as a skill that is central to nursing students' professional development. Due to the importance and the role of reflection in clinical areas of nursing, it is important to know how to achieve it. However, nursing trainers face the challenge of how to help their students to improve reflection in clinical settings. The aim of this study was to investigate the nursing students' experiences of facilitating reflection during clinical practice. This qualitative study was conducted by qualitative content analysis approach. Twenty nursing students during the second to eighth semester of their educational program were selected for participation using purposive sampling. Data were collected through in-depth semistructured interviews. The interview was transcribed verbatim, and qualitative content analysis was used to analyze the data. From the data analysis, four main themes were extracted. Motivation to reflect, complex experiences, efficient trainer, and effective relations were four main themes obtained from study that, in interaction with each other, had facilitating roles in students' reflective process on experiences. The findings revealed that the nursing students' reflection in clinical settings is effective in personal and professional level. Reflection of nursing students depends on motivational and educational factors and these factors increase the quality of care in patients. Furthermore, nursing educators need to create nurturing climate as well as supporting reflective behaviors of nursing students.

    Full Text Available As colleges of pharmacy prepare a new generation of practitioners, it is important that during practice experiences students learn the impact of clinical interventions. For over ten years, pharmacy students have been a vital part of the multidisciplinary team at the military treatment facility. The overall impact of the student interventions on patient care has not been evaluated. To evaluate the impact, the students began documenting their clinical interventions in Medkeeper RxInterventions™, an online database. The program is used to document faculty and fourth year pharmacy students’ pharmaceutical interventions.Objective: The objective of this study was to analyze the interventions completed by fourth year pharmacy students during a general medicine advanced pharmacy practice experience at a military treatment facility.Methods: The students completing their general medicine advanced pharmacy practice experience at the military treatment facility are responsible for self reporting all interventions made during clinical rounds into the Medkeeper RxIntervention™ database. The researchers retrospectively collected and analyzed interventions made from June 2008 to June 2009.Results: The total number of interventions recorded by 8 fourth year pharmacy students was 114. Students averaged a number of 14.3 interventions during an eight week practice experience. Students spent an average of 5 minutes per intervention. Ninety- five percent of the interventions were accepted.Conclusion: Fourth year pharmacy students’ recommendations were accepted at a high rate by resident physicians. The high acceptance rate may have the ability to positively impact patient care.

  6. Idiopathic pulmonary fibrosis: from clinical trials to real-life experiences

    Full Text Available Randomised controlled clinical trials are fundamental in medicine to develop new effective drugs and new therapeutic regimens and are the strength of evidence-based medicine. These studies allow us to avoid the repetition of misleading experiences that have been reported in the past, where drugs or associations were utilised without compelling evidence and ultimately proven to be ineffective. In recent years, randomised clinical trials have been conducted and concluded for many rare diseases, including idiopathic pulmonary fibrosis. However, clinical trials do not always reflect the real-life scenario. Patients selected for clinical trials present fewer comorbidities, they fall between certain age limits, and the severity of their disease is defined; therefore, they do not always reflect the whole of the population affected by a specific disease. These are the reasons why we also need data that mirror real-life experience. The limitations that these kind of studies present are always several and the studies should be interpreted with caution, although they can fill the important gap between efficacy and effectiveness. In this article, we will review the existing clinical data on real-life treatment of idiopathic pulmonary fibrosis.

    This study aimed to describe perceptions of clinical placement experiences and competency development for international speech-language pathology students and to determine if these perceptions were different for domestic students. Domestic and international students at two Australian universities participated in nine focus group interviews. Thematic analysis led to the identification of two themes shared by international and domestic students and several separate themes. Shared themes identified the important influence of students' relationships with clinical educators, unique opportunities and learning that occurs on placement. International student themes included concerns about their communication skills and the impact of these skills on client progress. They also explored their adjustment to unfamiliar placement settings and relationships, preferring structured placements to assist this adjustment. Domestic student themes explored the critical nature of competency attainment and assessment on placement, valuing placements that enabled them to achieve their goals. The findings of this study suggest that international students experience additional communication, cultural and contextual demands on clinical placement, which may increase their learning requirements. Clinical education practices must be responsive to the learning needs of diverse student populations. Strategies are suggested to assist all students to adjust to the professional and learning expectations of clinical education placements.

    Relapsing polychondritis (RP) is an uncommon disease that is characterized by inflammation and destruction of cartilaginous structures. When tracheobronchial tree is involved, respiratory obstructive symptoms can occur. A 35-year-old man, with a previous diagnosis of RP, was scheduled for rigid bronchoscopy to relieve dyspnea, caused by subglottic stenosis. After laser splitting of the subglottic web, the spontaneous respiration of the patient was insufficient, and hypercarbia developed progressively even with assisted ventilation. After 20 minutes of aggressive hyperventilation to reduce end-tidal CO2 level, sudden extreme tachycardia and hypotension developed. Ventilation rate was reduced and prolonged expiration time was allowed to alleviate a near-tampon status from dynamic hyperinflation. After the hemodynamic status was stabilized, the patient was transferred to the ICU for mechanical ventilation. He received ICU care for 30 days, and now, he was on supportive care on a ward, considering Y stent insertion to prevent luminal collapse from tracheobronchomalacia.

    Numerous studies have found that hallucinatory experiences occur in the general population. But to date, few studies have been conducted to compare clinical and nonclinical groups across a broad array of clinical symptoms that may co-occur with hallucinations. Likewise, hallucination-like experiences are measured as a multidimensional construct, with clinical and subclinical components related to vivid daydreams, intrusive thoughts, perceptual disturbance, and clinical hallucinatory experiences. Nevertheless, these individual subcomponents have not been examined across a broad spectrum of clinically disordered and nonclinical groups. The goal of the present study was to analyze the differences and similarities in the distribution of responses to hallucination-like experience in clinical and nonclinical populations and to determine the relation of these hallucination-like experiences with various clinical symptoms. These groups included patients with schizophrenia, non-psychotic clinically disordered patients, and a group of individuals with no psychiatric diagnoses. The results revealed that hallucination-like experiences are related to various clinical symptoms across diverse groups of individuals. Regression analysis found that the Psychoticism dimension of the Symptom Check List (SCL-90-R) was the most important predictor of hallucination-like experiences. Additionally, increased auditory and visual hallucination was the only subcomponent that differentiated schizophrenic patients from other groups. This distribution of responses in the dimensions of hallucination-like experiences suggests that not all the dimensions are characteristic of people hearing voices. Vivid daydreams, intrusive thoughts, and auditory distortions and visual perceptual distortions may represent a state of general vulnerability that does not denote a specific risk for clinical hallucinations. Overall, these results support the notion that hallucination-like experiences are closer to a

    In a baccalaureate nursing curriculum, students focused on the unique health care needs of veterans and their families. The learning experiences aimed to equip them with the knowledge, skills, and attitudes (KSAs) to provide holistic relation-centered care to veterans and their families. The clinical course integrated the findings of several veteran-centered publications and the American Association of Colleges of Nursing veteran-centered resources. Formative and summative anecdotal information was gathered in the learning experience during weekly postclinical discussions, course assignments, and a seminar after completion of the experience. Three noteworthy themes stand out: Increased Descriptions of Resources and Services Available to Veterans and Their Families, Increased Expressions of the Complex Health Care Needs of Veterans, and Increasing Recognition of the Autonomous Nature of the Community Health Nursing Role. Early indicators are that this community health field work experience will be sustainable into the future. The academic institution and clinical partner remain committed to working together to provide meaningful learning opportunities to students. Students completed the experience with increased KSAs and a beginning orientation to the Veterans Affairs Health Care System. [J Nurs Educ. 2017;56(3):186-190.]. Copyright 2017, SLACK Incorporated.

    Full Text Available Background. Clinical governance is considered crucial in primary care. Since 2005, clinical pathways have been experimentally implemented at the Local Health Authority of Monza Brianza (ASLMB, Italy, to develop general practitioners’ (GPs care of patients affected by some chronic diseases. The experimentation was aimed at introducing clinical governance in primary care, increasing GPs’ involvement in the care of their patients, and improving both patients’ and professionals’ satisfaction. In the period 2005-2006, 12% of the 763 employed GPs in the ASLMB were involved in the experiment, while this percentage increased to 15-20% in 2007-2008. Design and Methods. Twenty-four GPs were purposively sampled, randomly divided into two groups and asked to participate in focus groups (FGs held in 2008, aimed at evaluating their perception of the experiment. The FGs were audio-recorded, dialogues were typed out and undergone to a thematic analysis, according to the Interpretative Phenomenological Approach. Results. Four major themes emerged: i clinical pathways can result in GPs working in a more efficient and effective fashion; ii they can assure higher levels of both patient and professional satisfaction, since they sustain a caring approach and strengthen the GPs’ role; iii nevertheless, clinical pathways increase the bureaucratic workload and problems can arise in relationships among GPs and the LHA; iv the implementation of clinical pathways can be improved, especially by reducing bureaucracy and by assuring their continuity. Conclusions. Managerial aspects should be considered with care in order to experimentally introduce clinical pathways in general practice, and continuity of the experimentation should be guaranteed to improve GPs’ adherence and commitment.

  15. Clinical experience with recombinant human thrombopoietin in chemotherapy-induced thrombocytopenia.

    Since the identification and cloning of c-Mpl ligand, two forms of recombinant human thrombopoietin have undergone clinical development. Both the full-length molecule, known as rhTPO, and the truncated version of the molecule, known as pegylated recombinant human megakaryocyte growth and development factor (PEG-rHuMGDF), have been evaluated in phase I/II clinical trials in cancer patients receiving myelosuppressive chemotherapy. Early clinical trials with PEG-rHuMGDF in cancer patients demonstrated its clinical safety and platelet-stimulating activity. However, the development of neutralizing antibodies and clinically significant thrombocytopenia in some patients and normal donors who received PEG-rHuMGDF have led to discontinuation of clinical trials with this molecule in the United States. Clinical experience with rhTPO so far indicates that this full-length glycosylated molecule is remarkably well tolerated and has a favorable safety profile. In these studies, rhTPO exhibited dose-dependent increases in circulating platelet counts and bone marrow megakaryocytes before chemotherapy. In addition, there was an increase in the frequency and proliferation of bone marrow progenitor cells and mobilization of progenitors into the peripheral blood. Early results also showed that rhTPO can attenuate chemotherapy-induced severe thrombocytopenia and reduce the need for platelet transfusions. However, in this setting, the optimal schedule of rhTPO administration may depend on the length of the regimen and anticipated timing of the platelet nadir. These initial results indicate that rhTPO is a safe and potentially useful agent in the prevention and management of chemotherapy-induced thrombocytopenia. Results of larger randomized clinical trials will determine the therapeutic potential of this novel growth factor in various clinical settings.

Based on his years of clinical experience, it is proposed by Professor QIN that the Governor Vessel is mainly for miscellaneous disease and disease of limbs. Combined with distribution of cephalic motor region and meridian, an acupuncture treatment plan that is full of innovativeness is proposed, which is called Qin's eight scalp needles. It includes bilateral Fengchi (GB 20), Shuaigu (GB 8), Toulinqi (GB 15) as well as Yintang (GV 29) and Baihui (GV 20), mainly for treatment of nervous system diseases, such as PD and multiple sclerosis and so on. Besides, some outpatient cases are introduced to explain that eight scalp needle could alleviate the progression of PD, improve patients' motor, cognitive and affective disorders, reduce the suffering of patients, and improve the patient's quality of life.

    A model for the use of clinical hypnosis with a Little League population was proposed and outlined with dual emphasis: performance enhancement and resolving traumatic experiences. The Performance Enhancement Training Model was developed to enhance performance with this non-patient population. It employed clinical hypnosis to bring to fruition recommendations made by coaches to enhance players' batting proficiency. The second emphasis of the proposed model focused on the resolution of involuntary maladaptive habits secondary to a traumatic experience that impede or compromise optimum performance. Included in this category were detrimental defensive habits "at the plate" after a beaming by a pitch and detrimental defensive habits "on the field" after being hit by a batted ball.

    During life, many personal changes occur. These include changing house, school, work, and even friends and partners. However, the daily experience shows clearly that, in some situations, subjects are unable to change even if they want to. The recent advances in psychology and neuroscience are now providing a better view of personal change, the change affecting our assumptive world: (a) the focus of personal change is reducing the distance between self and reality (conflict); (b) this reduction is achieved through (1) an intense focus on the particular experience creating the conflict or (2) an internal or external reorganization of this experience; (c) personal change requires a progression through a series of different stages that however happen in discontinuous and non-linear ways; and (d) clinical psychology is often used to facilitate personal change when subjects are unable to move forward. Starting from these premises, the aim of this paper is to review the potential of virtuality for enhancing the processes of personal and clinical change. First, the paper focuses on the two leading virtual technologies – augmented reality (AR) and virtual reality (VR) – exploring their current uses in behavioral health and the outcomes of the 28 available systematic reviews and meta-analyses. Then the paper discusses the added value provided by VR and AR in transforming our external experience by focusing on the high level of personal efficacy and self-reflectiveness generated by their sense of presence and emotional engagement. Finally, it outlines the potential future use of virtuality for transforming our inner experience by structuring, altering, and/or replacing our bodily self-consciousness. The final outcome may be a new generation of transformative experiences that provide knowledge that is epistemically inaccessible to the individual until he or she has that experience, while at the same time transforming the individual’s worldview.

    Interstitial lung disease is the most common complication and cause of death among patients with scleroderma. Scleroderma-related interstitial lung disease has usually been treated with cyclophosphamide; however, its effect was evaluated to be modest and long-term administration of this drug is associated with adverse effects. Herein, we report our clinical experience of administering pirfenidone, which is an antifibrotic agent, in five patients with scleroderma-related interstitial lung disease. All patients demonstrated an increase in vital capacity.

    The objective of this study is to report on an in-depth evaluation of patient experiences and preferences at a Head and Neck Oncology outpatient clinic. A qualitative research design was used to determine the experiences and preferences of Head and Neck Cancer patients in an Oncology Outpatient Clinic, Maastricht University Medical Center, The Netherlands. Head and Neck Cancer Patients, treated for at least 6 months at the Oncology Clinic, were included. A qualitative research design with patient interviews was used. All interviews were recorded and transcribed verbatim to increase validity. Analysis was done with use of the template approach and qualitative data analysis software. Three of the six dimensions predominated in the interview: (1) respect for patients' values, preferences and expressed need, (2) information, communication and education and (3) involvement of family and friends. The dimensions physical comfort; emotional support; coordination and integration of care were considered to be of less significance. The findings from this study resulted in a deeper understanding of patients' experiences and preferences and can be useful in the transition towards a more patient-centered approach of health care.

    This article explores the experiences of older patients with cancer in phase 1 clinical trials. Conducting a case series of face-to-face, in-depth, open-ended interviews and using qualitative methods of analysis, we find that the psychosocial process of social comparison is relevant for understanding older adults' phase 1 clinical trial participation. Social comparison influences decisions to enroll in a phase 1 clinical trial, shapes perceptions of supportive care needs, and encourages the utilization of hope. Additional research should develop strategies for addressing supportive care needs among this patient cohort whose use of social comparison can inhibit articulation of pain, suffering, and symptom burden as well as use of informal support systems.

    We report on the evolution of the rapid access neurology clinic (established in 1995) at Addenbrooke's Hospital, Cambridge. Annualised attendance data demonstrate an ever increasing demand, with primary headache disorders now accounting for more than 40% of referrals. Secondary causes of headache (including intracranial tumours, idiopathic intracranial hypertension, carotid or vertebral artery dissection and subdural haematomas) remain infrequent. In all such cases, there were additional diagnostic clues. The number of patients referred with problems related to chronic neurological diseases has fallen considerably, reflecting the roles of specialist nurses and clinics. Imaging investigation of choice shifted from computerised tomography scan (45 to 16%) towards magnetic resonance imaging (17 to 47%). Management is increasingly on an outpatient basis, often without the need for a follow-up appointment. The experience presented here should inform further development of rapid access neurology clinics across the UK and suggests the need for acute headache services, in line with those for transient ischaemic attack and first seizure.

    Full Text Available Recently the attention for mirror exercises in therapies targeted specifically to body experience concerns has increased. This retrospective study will explore the mirror behaviour of anorexia nervosa (AN, bulimia nervosa (BN and non-clinical female subjects (CG and investigate whether mirror avoidance or checking are related to negative body experiences.The group of eating disorders consisted of 560 AN and 314 BN patients. The control group consisted of 1151 female subjects. The Body Attitude Test and the Eating Disorder Inventory subscales drive for thinness and body dissatisfaction were used. To explore the mirror behaviour, one item of the Body Attitude Test ‘I am observing my appearance in the mirror’ was used. Nonparametric analyses (Spearman rho correlations, Kruskal-Wallis and Mann Whitney test were used because of the categorical data.BN patients observed their body more often in the mirror than AN patients and the control subjects do. Age and BMI showed no significant main effect of mirror frequency. The relation between the frequency of mirror behaviour and body experience were significant but low (under .40. AN patients and control subjects with a mirror checking behaviour had a more negative body experience than those with mirror avoidance behaviour. In the BN group, no differences were found.There is support to integrate mirror exercises in a treatment of eating disorder patients. From a clinical point, mirror exercises are preferably combined with a body oriented therapy within a multidimensional cognitive behavioural approach. Recommendations for mirror exercises based on the clinical experience are given.

    Full Text Available Abstract Background Malignant melanoma occurs infrequently in Taiwan. Once it has progressed into osseous metastases, the prognosis is poor. There are no reported clinical experiences of surgical management in this area. Methods To improve our understanding of the rare clinical experiences, we retrospectively investigated clinical characteristics, radiological findings, treatment modalities, survival outcomes and prognoses of 11 Taiwanese patients with osseous metastasis of melanoma treated surgically at two national medical centers, National Taiwan University Hospital and National Cheng Kung University Hospital from January 1983 to December 2006. Results Six patients suffered from acral-lentiginous melanoma. Nine patients sustained multiple osseous metastases and most lesions were osteolytic. Nine patients also had sustained metastases to other organs including liver, lungs, lymph nodes, brain and spleen. Second malignancies including lung cancer, thyroid papillary carcinoma, renal cell carcinoma and cervical cancer co-existed in four patients. The interval from the initial diagnosis of melanoma to the clinical detection of osseous metastases varied from 0–37.8 months (mean 9.75 months. Metastatic melanoma was invariably fatal; the mean survival time from bone metastases to death was 5.67 months. Conclusion Due to the high morbidity and poor survival of Taiwanese patients with osseous metastases of melanoma, surgical treatment should be directed towards pain relief and the prevention of skeletal debilitation in order to maintain their quality of life.

    The objectives were to evaluate the relationships among music perception, appraisal, and experience in cochlear implant users in multiple clinical settings and to examine the viability of two assessments designed for clinical use. Background questionnaires (IMBQ) were administered by audiologists in 14 clinics in the United States and Canada. The CAMP included tests of pitch-direction discrimination, and melody and timbre recognition. The IMBQ queried users on prior musical involvement, music listening habits pre and post implant, and music appraisals. One-hundred forty-five users of Advanced Bionics and Cochlear Ltd cochlear implants. Performance on pitch direction discrimination, melody recognition, and timbre recognition tests were consistent with previous studies with smaller cohorts, as well as with more extensive protocols conducted in other centers. Relationships between perceptual accuracy and music enjoyment were weak, suggesting that perception and appraisal are relatively independent for CI users. Perceptual abilities as measured by the CAMP had little to no relationship with music appraisals and little relationship with musical experience. The CAMP and IMBQ are feasible for routine clinical use, providing results consistent with previous thorough laboratory-based investigations.

  10. How to Recondition Ex Vivo Initially Rejected Donor Lungs for Clinical Transplantation: Clinical Experience from Lund University Hospital

    Sandra Lindstedt

    2011-01-01

    Full Text Available A major problem in clinical lung transplantation is the shortage of donor lungs. Only about 20% of donor lungs are accepted for transplantation. We have recently reported the results of the first six double lung transplantations performed with donor lungs reconditioned ex vivo that had been deemed unsuitable for transplantation by the Scandiatransplant, Eurotransplant, and UK Transplant organizations because the arterial oxygen pressure was less than 40 kPa. The three-month survival of patients undergoing transplant with these lungs was 100%. One patient died due to sepsis after 95 days, and one due to rejection after 9 months. Four recipients are still alive and well 24 months after transplantation, with no signs of bronchiolitis obliterans syndrome. The donor lungs were reconditioned ex vivo in an extracorporeal membrane oxygenation circuit using STEEN solution mixed with erythrocytes, to dehydrate edematous lung tissue. Functional evaluation was performed with deoxygenated perfusate at different inspired fractions of oxygen. The arterial oxygen pressure was significantly improved in this model. This ex vivo evaluation model is thus a valuable addition to the armamentarium in increasing the number of acceptable lungs in a donor population with inferior arterial oxygen pressure values, thereby, increasing the lung donor pool for transplantation. In the following paper we present our clinical experience from the first six patients in the world. We also present the technique we used in detail with flowchart.

    Full Text Available Introduction: In pediatric dentistry, the experiences of dental students may help dental educators better prepare graduates to treat the children. Research suggests that student′s perceptions should be considered in any discussion of their education, but there has been no systematic examination of India′s undergraduate dental students learning experiences. Aim: This qualitative investigation aimed to gather and analyze information about experiences in pediatric dentistry from the students′ viewpoint using critical incident technique (CIT. Study Design: The sample group for this investigation came from all 240 3 rd and 4 th year dental students from all the four dental colleges in Indore. Using CIT, participants were asked to describe at least one positive and one negative experience in detail. Results: They described 308 positive and 359 negative experiences related to the pediatric dentistry clinic. Analysis of the data resulted in the identification of four key factors related to their experiences: 1 The instructor; 2 the patient; 3 the learning process; and 4 the learning environment. Conclusion: The CIT is a useful data collection and analysis technique that provides rich, useful data and has many potential uses in dental education.

    Little is known about the consequences of moral distress. The purpose of this study was to identify clinical situations that caused nurses to experience moral distress, to understand the consequences of those situations, and to determine whether nurses would change their practice based on their experiences. The investigation used a descriptive approach. Open-ended surveys were distributed to a convenience sample of 204 critical care nurses employed at a university medical center. The analysis of participants' responses used an inductive approach and a thematic analysis. Each line of the data was reviewed and coded, and the codes were collapsed into themes. Methodological rigor was established. Forty-nine nurses responded to the survey. The majority of nurses had experienced moral distress, and the majority of situations that caused nurses to experience moral distress were related to end of life. The nurses described negative consequences for themselves, patients, and families.

    Full Text Available Background: Major reforms in the NHS in England have resulted in the creation of Clinical Commissioning Groups, which put clinicians at the forefront of commissioning services. One of the shared strategic objectives of the NHS is ‘ensuring that people have a positive experience of care’. With this in mind, a piece of work was undertaken to develop a strategy to embed patient experience in the commissioning process. Aim: The overall aim of this work was to engage with patients, service users, carers, health and social care workers and representatives from the voluntary sector in north-west London, UK, to develop a shared definition of patient experience and a patient experience strategy to influence the clinical commissioning of care. Methods: A values-based approach was used to develop the definition and strategy, working collaboratively with clinicians, commissioners, patients, service users, carers and the community. The facilitation of this work was underpinned by four principles: working collaboratively; being evidence based; being asset based; and being continuous and iterative. The principles are described and also used to critique the process and outcomes. Conclusion: This work was stimulated by the recognition that practice development approaches could be applied to different contexts and settings, including clinical commissioning. It has the potential to draw clinical commissioning and clinical provision much closer together, with engagement, collaboration and decision making focused on improving the quality of care (experience, safety and outcomes for patients and their supporters. Implications for practice: •\tA values-based approach is an effective way of capturing the voice of patients, service users, carers and the community •\tThe voices of individuals and communities are crucial in shaping and influencing the development and commissioning of new models of care •\tGreater impact may have been achieved if we had worked

    The low English proficiency of Chinese nurse/nursing students affects their performance when they work in English-speaking countries. However, limited resources are available to help them improve their workplace English, i.e. English used in a clinical setting. To this end, it is essential to look for an appropriate and effective means to assist them in improving their clinical English. The objective of this study is to evaluate the learning experience of Chinese nursing students after they have completed an online clinical English course. Focus group interview was used to explore their learning experience. 100 students in nursing programs at Tung Wah College were recruited. The inclusion criteria were: (1) currently enrolled in a nursing program; and (2) having clinical experience. Eligible participants self-registered for the online English course, and were required to complete the course within 3 months. After that, semi-structured interviews were conducted on students whom completed the whole and less than half of the course. One of the researchers joined each of the interviews as a facilitator and an observer. Thematic analysis was used to analyze the data. Finally, 7 themes emerged from the interviews: technical issues, adequacy of support, time requirement, motivation, clarity of course instruction, course design, and relevancy of the course. Participants had varied opinions on the 2 themes: motivation and relevancy of the course. Overall, results of this study suggest that the online English course helped students improve their English. Factors which support their learning are interactive course design, no time constraint, and relevancy to their work/study. Factors which detracted from their learning are poor accessibility, poor technical and learning support and no peer support throughout the course.

    Changes in the routine immunization schedule are common and may pose challenges to primary care clinics. We sought to assess the experiences of U.S. providers and clinic staff during the introduction of 9-valent HPV vaccine. In 2015-2016, we conducted a survey in a probability sample of 127 pediatric (40%) and family medicine (60%) clinics in three U.S. states. The 211 respondents included clinicians (63%) and staff (37%). Overall, 83% of clinics stocked 9-valent HPV vaccine, with adoption ranging from 60% among early respondents to 100% among later respondents. Almost all respondents believed that providers in their clinics would recommend the 9-valent vaccine as strongly as (66%) or more strongly than (33%) the quadrivalent vaccine. Over half (61%) had no concerns about the 9-valent vaccine, while others reported concerns about increased parental hesitancy (29%), private insurance coverage (17%), or other issues (10%). Respondents from pediatric versus family medicine clinics more often reported a concern (OR = 2.06, 95% CI 1.02-4.15). Among the 169 respondents who stocked 9-valent vaccine, about half (56%, n = 94) anticipated that providers in their clinics would recommend a "booster" dose of 9-valent HPV vaccine for adolescents who had completed the 3-dose series with prior versions. Among the 42 respondents who did not stock 9-valent vaccine, few (17%, n = 7) believed providers would recommend adolescents delay vaccination until it was available. In conclusion, providers and staff generally had positive views of 9-valent HPV vaccine and many had no concerns. For others, responses regarding parental hesitancy, insurance coverage, and the use of booster doses suggests opportunities for enhancing future educational support.

    An 80-year-old Japanese woman with wet cough and dyspnea was diagnosed with pneumonia at a clinic. Antibiotics did not improve her symptoms; therefore, she was referred to our hospital one month after symptom onset. Chest radiograph findings revealed complete collapse of the left lung. Bronchoscopy showed white mucus plug in the left main bronchus, which could not be removed. She was initially treated with bromhexine. Subsequently, culture results of the mucus plug specimen obtained during bronchoscopy yielded Schizophyllum commune. After three weeks, improvement of the collapsed lung was observed on chest radiograph.

    Purpose: Post-treatment radiation injury to central and peripheral airways is a potentially important, yet under-investigated determinant of toxicity in lung stereotactic ablative radiotherapy (SAbR). We integrate virtual bronchoscopy technology into the radiotherapy planning process to spatially map and quantify the radiosensitivity of bronchial segments, and propose novel IMRT planning that limits airway dose through non-isotropic intermediate- and low-dose spillage. Methods: Pre- and ∼8.5 months post-SAbR diagnostic-quality CT scans were retrospectively collected from six NSCLC patients (50–60Gy in 3–5 fractions). From each scan, ∼5 branching levels of the bronchial tree were segmented using LungPoint, a virtual bronchoscopic navigation system. The pre-SAbR CT and the segmented bronchial tree were imported into the Eclipse treatment planning system and deformably registered to the planning CT. The five-fraction equivalent dose from the clinically-delivered plan was calculated for each segment using the Universal Survival Curve model. The pre- and post-SAbR CTs were used to evaluate radiation-induced segmental collapse. Two of six patients exhibited significant segmental collapse with associated atelectasis and fibrosis, and were re-planned using IMRT. Results: Multivariate stepwise logistic regression over six patients (81 segments) showed that D0.01cc (minimum point dose within the 0.01cc receiving highest dose) was a significant independent factor associated with collapse (odds-ratio=1.17, p=0.010). The D0.01cc threshold for collapse was 57Gy, above which, collapse rate was 45%. In the two patients exhibiting segmental collapse, 22 out of 32 segments showed D0.01cc >57Gy. IMRT re-planning reduced D0.01cc below 57Gy in 15 of the 22 segments (68%) while simultaneously achieving the original clinical plan objectives for PTV coverage and OAR-sparing. Conclusion: Our results indicate that the administration of lung SAbR can Result in significant injury to

    The question of how animal studies should be designed, conducted, and analyzed remains underexposed in societal debates on animal experimentation. This is not only a scientific but also a moral question. After all, if animal experiments are not appropriately designed, conducted, and analyzed, the results produced are unlikely to be reliable and the animals have in effect been wasted. In this article, we focus on one particular method to address this moral question, namely systematic reviews of previously performed animal experiments. We discuss how the design, conduct, and analysis of future (animal and human) experiments may be optimized through such systematic reviews. In particular, we illustrate how these reviews can help improve the methodological quality of animal experiments, make the choice of an animal model and the translation of animal data to the clinic more evidence-based, and implement the 3Rs. Moreover, we discuss which measures are being taken and which need to be taken in the future to ensure that systematic reviews will actually contribute to optimizing experimental design and thereby to meeting a necessary condition for making the use of animals in these experiments justified.

    Full Text Available Abstract The World Health Organization has recently added Interprofessional Education (IPE to its global health agenda recognizing it as a necessary component of all health professionals' education. We suggest mandatory interprofessional shadowing experiences as a mechanism to be used by chiropractic institutions to address this agenda. IPE initiatives of other professions (pharmacy and medicine are described along with chiropractic. This relative comparison of professions local to our jurisdiction in Ontario, Canada is made so that the chiropractic profession may take note that they are behind other health care providers in implementing IPE. Interprofessional shadowing experiences would likely take place in a multi-disciplinary clinical setting. We offer an example of how two separate professions within a Family Health Team (FHT can work together in such a setting to enhance both student learning and patient care. For adult learners, using interprofessional shadowing experiences with learner-derived and active objectives across diverse health professional groups may help to improve the educational experience. Mandatory interprofessional shadowing experiences for chiropractors during their training can enhance future collaborative practice and provide success in reaching a goal common to each profession - improved patient care.

    2013-09-01

    The aim of this research was to study how a web-based discussion forum can be used as a supervision tool during nursing students' clinical training. The study emphasises peer support and its importance for the students. The empirical research was carried out at a Finnish university of applied sciences. 25 nursing students took part in web-based discussion during their eight-week clinical training period. All in all, 395 comments were submitted. The material was analysed by using categorisation and a thematic analysis process. Finally, the results were reported using a modified Salmon's (2002) 5-stage model of Teaching and Learning On-line and Mezirow's (1981) levels of reflection. The students motivated each other by sharing their feelings and experiences. They noticed the value of peer support and started to learn from each other as well. By reflecting on their experiences, the students progressed in their learning process and at the same time advanced their reflective thinking process. This combination of theoretical knowledge and practice, based on the students' needs and interests, could lead to a deeper understanding which could also result in better clinical skills. This method offers the lecturers the possibility to support and follow the professional growth process in a new evidence-based manner.

    The aim of this paper is to analyse, after clinical experience with a series of patients with established diagnoses and review of the literature, all relevant anamnestic features in order to build a simple diagnostic algorithm for vertigo in childhood. This study is a retrospective chart review. A series of 37 children underwent complete clinical and instrumental vestibular examination. Only neurological disorders or genetic diseases represented exclusion criteria. All diagnoses were reviewed after applying the most recent diagnostic guidelines. In our experience, the most common aetiology for dizziness is vestibular migraine (38%), followed by acute labyrinthitis/neuritis (16%) and somatoform vertigo (16%). Benign paroxysmal vertigo was diagnosed in 4 patients (11%) and paroxysmal torticollis was diagnosed in a 1-year-old child. In 8% (3 patients) of cases, the dizziness had a post-traumatic origin: 1 canalolithiasis of the posterior semicircular canal and 2 labyrinthine concussions, respectively. Menière's disease was diagnosed in 2 cases. A bilateral vestibular failure of unknown origin caused chronic dizziness in 1 patient. In conclusion, this algorithm could represent a good tool for guiding clinical suspicion to correct diagnostic assessment in dizzy children where no neurological findings are detectable. The algorithm has just a few simple steps, based mainly on two aspects to be investigated early: temporal features of vertigo and presence of hearing impairment. A different algorithm has been proposed for cases in which a traumatic origin is suspected.

    In 2006, the European Medicines Agency (EMA) approved Omnitrope(®) as a biosimilar recombinant human growth hormone (rhGH), on the basis of comparable quality, safety, and efficacy to the reference medicine (Genotropin(®), Pfizer). Data continue to be collected on the long-term efficacy of biosimilar rhGH from several on-going postapproval studies. Particular topics of interest include efficacy in indications granted on the basis of extrapolation, and whether efficacy of growth hormone treatment is affected when patients are changed to biosimilar rhGH from other rhGH products. Data from clinical development studies and 10 years of postapproval experience affirm the clinical efficacy and effectiveness of biosimilar rhGH across all approved indications. In addition, the decade of experience with biosimilar rhGH since it was approved in Europe confirms the scientific validity of the biosimilar pathway and the approval process. Concerns about clinical effect in extrapolated indications, and also about the impact of changing from other rhGH preparations, have been alleviated. Biosimilar rhGH is an effective treatment option for children who require therapy with rhGH.

    At the 8th Annual Congress of the European Association for Haemophilia and Allied Disorders (EAHAD) held in Helsinki, Finland, in February 2015, Pfizer sponsored a satellite symposium entitled: 'Haemophilia in a real-world setting: The value of clinical experience in data collection' Co-chaired by Riitta Lassila (Helsinki University Central Hospital, Helsinki, Finland) and Gerry Dolan (Guy's and St Thomas' Hospital, London, UK); the symposium provided an opportunity to explore the practical value of real-world data in informing clinical decision-making. Gerry Dolan provided an introduction to the symposium by describing what is meant by real-world data (RWD), stressing the role RWD can play in optimising patient outcomes in haemophilia and highlighting the responsibility of all stakeholders to collaborate in continuous data collection. Kristian Juusola (Oulu University Hospital, Oulu, Finland) then provided personal experience as a haemophilia nurse around patient views on adherence to treatment regimes, and how collecting insights into real-world use of treatment can shape approaches to improving adherence. The importance of elucidating pharmacokinetic parameters in a real-world setting was then explored by Vuokko Jokela (Helsinki University, Helsinki, Finland). Finally, Alfonso Iorio (McMaster University, Hamilton, Ontario, Canada) highlighted the importance of quality data collection in translating clinical reality into scientific advances.

    Full Text Available Non-clinical psychotic experiences are common and distressing. It has been hypothesized that early life vitamin D deficiency may be a risk factor for psychosis-related outcomes, but it is not known if circulating concentrations of 25-hydroxyvitamin D (25(OHD during childhood are associated with psychosis-related outcomes or whether the two different forms of 25(OHD, (25(OHD(3 and 25(OHD(2, have similar associations with psychosis-related outcomes.We investigated the association between serum 25(OHD(3 and 25(OHD(2 concentrations and psychotic experiences in a prospective birth cohort study. Serum 25(OHD(3 and 25(OHD(2 concentrations were measured at mean age 9.8 years and psychotic experiences assessed at mean age 12.8 years by a psychologist (N = 3182.Higher 25(OHD(3 concentrations were associated with lower risk of definite psychotic experiences (adjusted odds ratio: OR (95% confidence interval: CI 0.85 (0.75-0.95. Higher concentrations of 25(OHD(2 were associated with higher risk of suspected and definite psychotic experiences (adjusted odds ratio: OR (95% confidence interval: CI 1.26 (1.11, 1.43. Higher 25(ODD(2 concentrations were also weakly associated with definite psychotic experiences (adjusted OR (95% CI 1.17 (0.96, 1.43, though with wide confidence intervals including the null value.Our findings of an inverse association of 25(OHD(3 with definite psychotic experiences is consistent with the hypothesis that vitamin D may protect against psychosis-related outcomes.

    The quality of any medical treatment depends on the accurate processing of multiple complex components of information, with proper delivery to the patient. This is true for radiation oncology, in which treatment delivery is as complex as a surgical procedure but more dependent on hardware and software technology. Uncorrected errors, even if small or infrequent, can result in catastrophic consequences for the patient. We developed electronic checklists (ECLs) within the oncology electronic medical record (EMR) and evaluated their use and report on our initial clinical experience. Using the Mosaiq EMR, we developed checklists within the clinical assessment section. These checklists are based on the process flow of information from one group to another within the clinic and enable the processing, confirmation, and documentation of relevant patient information before the delivery of radiation therapy. The clinical use of the ECL was documented by means of a customized report. Use of ECL has reduced the number of times that physicians were called to the treatment unit. In particular, the ECL has ensured that therapists have a better understanding of the treatment plan before the initiation of treatment. An evaluation of ECL compliance showed that, with additional staff training, > 94% of the records were completed. The ECL can be used to ensure standardization of procedures and documentation that the pretreatment checks have been performed before patient treatment. We believe that the implementation of ECLs will improve patient safety and reduce the likelihood of treatment errors.

    Canadian Blood Services runs approximately 16,000 donor clinics annually. While there were more than 220 different clinic configurations used in 2011 and 2012, 67% of all clinic configurations followed one of 51 standard models. As part of operational planning for current and future configurations it was necessary for Canadian Blood Services to calculate staffing requirements for standard clinic models. In this article we present a method that incorporates both cost control and impact on donor experience. We calculate staffing requirements to minimize costs, but adjust using queuing theory to ensure donor wait time metrics are met. The method can be applied in a wide variety of situations. Although developed for a particular study, the methods described in this article can be applied in a wide variety of situations. A case study in which the model is used to review existing staffing arrangements at Canadian Blood Services is presented. The staffing model can be used to balance the requirements of minimizing staffing costs with that of ensuring that donors do not suffer unnecessary delays. Moreover, in an example application, savings of 3.4% were identified through the modeling process. © 2013 American Association of Blood Banks.

    Extrinsic allergic alveolitis is an interstitial lung disease caused by exposure to a variety of inhaled antigens. In Mexico, the most frequent form is due to the inhalation of avian antigens, markedly pigeon proteins. Depending on type and time exposure, the disease presents different clinical forms usually characterized by progressive dyspnea, ground glass or reticulonodular images on chest x rays, a restrictive functional pattern, rest hypoxemia worsening with exercise, and increase of T lymphocytes in bronchoalveolar lavage with an inversion in the helper/suppressor ratio. In this paper, we discuss a 15-year experience with this pathological problem in Mexico, emphasizing the differences with this disorder in Caucasian populations. Generally, our patients display a chronic form of the disease, which evolves to fibrosis in about one-half of the patients. In this sense, the diagnostic, prognostic, and therapeutic focusing exhibit different elements, and thus the development of clinical and basic research is strongly required.

    The average length of stay on psychiatric inpatient units has decreased in the past 40 years from 24.9 to 7.2 days. Inpatient psychiatric nurses are challenged to meet the standards and scope of practice despite the changing circumstances of their work environment. The amount of time student nurses spend with a given patient has been affected by changes in acute psychiatric inpatient care and decreased length of stay; however, opportunities exist for effective termination of the nurse-client relationship. Facilitation of students' awareness and understanding of the dynamics inherent in the termination process is an important teaching task for psychiatric nursing clinical instructors. In the current article, a clinically focused learning activity using structured prompts to guide and promote psychiatric nursing students' experiences with the process of termination is described and teaching strategies are discussed.

    Few researchers have explored the clinical experiences of complementary and alternative medical practitioners and students, including the emotion work they perform. In this article, using a constant comparison approach and a heuristic framework (a dramaturgical perspective), we analyze semistructured interviews with 9 undergraduate practitioners in training to examine challenges experienced when students first attend to patients. A feature of students' learning about clinical work concerned performance in a public arena and associated demands placed on the inchoate practitioner. Preliminary patient consultations represented a dramatic rite of passage and initiation into a transitional phase in professional identity. Juggling the roles of student and practitioner within an observed consultation led to anticipatory anxiety, impression management strategies, and conflict with other individuals. Of the coping strategies, participants regarded sharing and feedback from peer groups as most effective in examining and resolving the challenges of becoming a practitioner.

    The latest literature describing clinical experiences with peritoneal dialysis solutions low in glucose degradation products (GDPs) is mostly consistent with previous reports suggesting less inflammation, better peritoneal mesothelial mass preservation, a lower rate of decline of residual renal function, and improved patient survival. The data suggest stable peritoneal transport rates, but no definite evidence has yet emerged of superior membrane preservation. Most studies have reported very low peritonitis rates, but without significant differences as compared with rates in patients exposed to conventional solutions. New, appropriately powered randomized clinical trials are needed to confirm the potential benefits of low-GDP solutions and to establish the role of renal function preservation with regard to those benefits.

    The study objective was to assess predoctoral dental students' experience with a caries risk assessment computer program in the pediatric dentistry clinic at Marquette University School of Dentistry. In 2005, spring semester sophomore dental students (class of 2008) were introduced to the caries risk assessment computer program "Cariogram." The students received a fifty-minute lecture on caries risk assessment and a demonstration on how to use Cariogram in the clinic. After two years of clinical exposure to Cariogram, sixty-six out of eighty senior dental students completed an anonymous eleven-item questionnaire on their experience with the tool. Each item on the questionnaire was scored on a five-point Likert scale with the exception of two questions. Full- and part-time faculty members in the pediatric dentistry clinic were involved in teaching and supervising students in the use of Cariogram for caries risk assessment after their training and calibration. Forty-five percent of the students who participated in the study agreed that Cariogram was easy to understand, and 18 percent disagreed. Thirty-six percent felt that it was easy to apply, and 25 percent reported that it was useful in determining caries preventive procedures. The students reported that 60 percent of full-time and 33 percent of part-time faculty were knowledgeable about Cariogram use. A majority of the students felt that Cariogram was not easy to understand, and eighty-two percent of them reported that they would not be using Cariogram in their private offices. Future studies should explore reasons why students do not feel inclined to use Cariogram as a caries risk assessment tool in their private practices even after being exposed to the tool in dental school.

    Foreign body (FB) removal in our hospital was almost exclusively performed by surgeons through a rigid bronchoscope until the pulmonologists started getting involved in FB extraction. This study aimed to retrospectively review the results of 2 years of experience with 120 patients who presented or were referred to the Pulmonary Medicine Department, Ain Shams University Hospital in Cairo, Egypt, with clinical suspicion of FB aspiration during the period between December 2006 and December 2008. FBs were removed by either rigid and/or flexible bronchoscopy using either general or topical anesthesia. There were 54 male and 66 female patients with an age range between 3 months and 70 years and 68.5% of the patients were under the age of 10 years. Ninety patients (75%) presented with a definite history of FB aspiration, with a time interval between aspiration and presentation ranging between less than 6 hours and 12 months. The FB was visible on the chest x-ray in 42 cases. Aspirations were primarily into the right lung (53.2%). Seeds and scarf pins were the most common FB found, and were retrieved in 36 cases. Pulmonologists were successful in extracting 110 out of 111 (99.1%) bronchoscopically visualized FBs, and open thoracotomy was required in only 1 case for FB removal. In another 6 cases, only mucous plug was found to be the endogenous FB, whereas no FB could be found in 3 cases. No mortality or serious complications took place during or after the bronchoscopy. In conclusion, pulmonologists can extract FBs easily and safely either by using rigid and/or flexible bronchoscopes if they have the appropriate experience.

    Demographic changes, technological developments and rising expectations require the analysis of public-private primary care (PC) service provision to inform policy makers. We conducted a descriptive, cross-sectional study using the dataset of the Maltese arm of the QUALICOPC Project to compare the PC patients' experiences provided by public-funded and private (independent) general practitioners in Malta. Seven hundred patients from 70 clinics completed a self-administered questionnaire. Direct logistic regression showed that patients visiting the private sector experienced better continuity of care with more difficulty in accessing out-of-hours care. Such findings help to improve (primary) healthcare service provision and resource allocation.

    2007-01-01

    Summary Water jets have been used in many areas of surgery. Recently a new surgical debridement device was launched onto the market - VersajetTM. VersajetTM is a unique hydrosurgical device that uses a precise jet of water to simultaneously hold, cut, and remove devitalized or necrotic tissue. This paper describes our experience with ten patients comparing Weck knives with the newly designed hydrosurgical device when debriding burn wounds. The patients' age ranged from 27 to 60 yr (average, 37.8 yr) and the burn wounds treated were between 3 and 7% total body surface area, involving the face, abdomen, and limbs. The hydrosurgical system is a very useful tool for irregular and complex burn wound debridement. This paper represents the first written clinical experience utilizing hydrosurgery in the burn wound management in an Eastern country. PMID:21991073

    This qualitative study examined clinical psychology trainees' experiences of using, or not using, therapist self-disclosure and their experience of training and supervision on this issue. Fourteen trainees were interviewed and their accounts analyzed using interpretative phenomenological analysis, yielding nine themes organized into two domains. The first domain ("the decision in the moment") concerned participants' struggle with decision making about disclosure; the second ("the developing therapist") reflected their evolving ideas about disclosure over training and within the wider philosophical context of therapy. The dilemmas surrounding disclosure seemed to distill some central issues associated with participants' developing professional therapist identity. Working out one's position on self-disclosure is a challenge that trainee therapists may require support in mastering.

    Patients with glioblastoma multiforme (GBM) require radiotherapy as part of definitive management. Our institution has adopted the use of volumetric arc therapy (VMAT) due to superior sparing of the adjacent organs at risk (OARs) compared to intensity modulated radiation therapy (IMRT). Here we report our clinical experience by analyzing target coverage and sparing of OARs for 90 clinical treatment plans. VMAT and IMRT patient cohorts comprising 45 patients each were included in this study. For all patients, the planning target volume (PTV) received 50 Gy in 30 fractions, and the simultaneous integrated boost PTV received 60 Gy. The characteristics of the two patient cohorts were examined for similarity. The doses to target volumes and OARs, including brain, brainstem, hippocampi, optic nerves, eyes, and cochleae were then compared using statistical analysis. Target coverage and normal tissue sparing for six patients with both clinical IMRT and VMAT plans were analyzed. PTV cove
