    The surgical Ultrasonic Aspirator (USA) is a fairly new surgical instrument used for an increasingly wide range of procedures. This paper introduces a new application: debridement of vulvovaginal necrotic ulcers resulting from intracavitary radiation therapy. The ultrasonic aspirator allowed removal of the soft, necrotic tissue while preserving underlying healthy, firm tissue and blood vessels

    Brain cancer research has been hampered by a paucity of viable clinical tissue of sufficient quality and quantity for experimental research. This has driven researchers to rely heavily on long term cultured cells which no longer represent the cancers from which they were derived. Resection of brain tumors, particularly at the interface between normal and tumorigenic tissue, can be carried out using an ultrasonic surgical aspirator (CUSA) that deposits liquid (blood and irrigation fluid) and resected tissue into a sterile bottle for disposal. To determine the utility of CUSA-derived glioma tissue for experimental research, we collected 48 CUSA specimen bottles from glioma patients and analyzed both the solid tissue fragments and dissociated tumor cells suspended in the liquid waste fraction. We investigated if these fractions would be useful for analyzing tumor heterogeneity, using IHC and multi-parameter flow cytometry; we also assessed culture generation and orthotopic xenograft potential. Both cell sources proved to be an abundant, highly viable source of live tumor cells for cytometric analysis, animal studies and in-vitro studies. Our findings demonstrate that CUSA tissue represents an abundant viable source to conduct experimental research and to carry out diagnostic analyses by flow cytometry or other molecular diagnostic procedures

    Full Text Available Abstract Background Despite breast abscess becoming less common in developed countries, it has remained one of the leading causes of morbidity in women in developing countries. A randomized controlled trial was conducted at Mulago hospital complex in Kampala Uganda to establish whether ultrasound guided needle aspiration is a feasible alternative treatment option for breast abscesses. Results A total of 65 females with breast abscess were analyzed, of these 33 patients were randomized into the ultrasound guided needle aspiration and 32 patients in the Incision and drainage arm. The mean age was 23.12, most of them were lactating (66.2%, primipararous (44.6% with peripheral abscesses (73.8% located in the upper lateral quadrant (56%.The mean breast size was 3.49 cm. The two groups were comparably in demographic characteristic and breast abscess size. Survival analysis showed no difference in breast abscess healing rate between the two groups (Log rank 0.24 df 1 and P = 0.63. Incision and drainage was found to be more costly than ultrasound guided aspiration (cost effective ratio of 2.85. Conclusion Ultrasound guided needle aspiration is therefore a feasible and cost effective treatment option for both lactating and non lactating breast abscesses with a diameter up to 5 cm by ultrasound in an immune competent patient

    Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a useful and less invasive procedure for the definitive diagnosis of mediastinal and hilar lymph nodes. However, infectious complications can occur after EBUS-TBNA, although they are extremely rare. A 66-year-old man with necrotic and swollen lower paratracheal lymph nodes underwent EBUS-TBNA. A mediastinal abscess developed 9 days post-procedure. Surgical drainage and debridement of the abscess were performed along with lymph node biopsy followed by daily washing of the thoracic cavity. Surgical treatment was effective, leading to remission of the abscess. Biopsy revealed that the tumor was squamous cell carcinoma with no radiologically detected cancer elsewhere in the body. Mediastinal lung cancer was thus confirmed. Subsequent chemoradiotherapy led to the remission of the tumor. Mediastinitis after EBUS-TBNA is rare but should be considered, particularly if the target lymph nodes are necrotic. Mediastinitis can lead to serious and rapid deterioration of the patient's condition, for which surgical intervention is the treatment of choice.

    To evaluate the outcome and assess the success rate of ultrasound guided aspiration of breast abscess as an alternative to surgical incision and drainage. Methodology: A prospective descriptive study was carried out at Department of Surgery, Chandka Medical College Hospital, Larkana, Pakistan, from January 2015 to December 2015. A total of 111 patients of breast abscess who underwent ultrasound guided aspiration without anesthesias with oral antibiotic cover were studied. Females with breast abscess within seven days, and the abscess size was <3cm were included in the study. Males, antibioma and inflammatory carcinoma were excluded from the study. Outcome of success or failure was observed within two weeks and recorded. Results: Out of 111 patients, 68.46% were lactating and 31.53% were non-lactating women, with ages ranging from 18 to 60 years (mean 36.5 years). The successful rate with complete resolution after ultrasound guided aspiration was observed in 94.5%. 80.82% responded after single aspiration, 12.38% after two times aspiration, and 6.66% after multiple aspirations, while 5.4% of patients required incision and drainage. Conclusion: Ultrasound guided aspiration of breast abscess is an effective treatment option with a diameter of <3cm, which can be recommended as a routine outpatient procedure. (author)

    The critical shortage of human resources for healthcare falls most heavily on sub-Saharan nations such as Sierra Leone, where such workforce deficits have grave impacts on its burden of surgical disease. An important aspect in retention and development of the workforce is training. This study focuses on postgraduate surgical training (formal and short course) and perceptions of opportunities, challenges and aspirations, in a country where more than half of surgical procedures are performed by medical officers. The study presents findings from 12 in-depth semi-structured interviews conducted with medical officers by the primary investigator in Sierra Leone between April and June 2017. Each interview was transcribed alongside an introspective reflexive journal to acknowledge and account for researcher biases. Two interviewees had accessed postgraduate surgical training and 10 (83%) had accessed short course surgically relevant training. The number of short courses accessed grew higher the more recently the medical officers had graduated. Supervision, short length and international standards were the most appreciated aspects of short training courses. Some medical officers perceived the formal postgraduate surgical training programme to be ill-equipped, doubting its credibility. This demotivated some from applying. Training is an essential aspect of developing an adequate surgical workforce. Faith must be restored in the capabilities of Sierra Leone's Ministry of Health and Sanitation to provide adequate and sustainable training. This study advocates for the use of short courses to restore this faith and the expansion of postgraduate surgical training to the districts through developing a regional teaching complex to provide short courses and eventually formal postgraduate training in the future.

    The purpose was to describe aspiration pneumonia in the context of other lung infections and aspiration syndromes and to distinguish between the main scenarios commonly implied when the terms aspiration or aspiration pneumonia are used. Finally, we aim to summarize current evidence surrounding the diagnosis, microbiology, treatment, risks, and prevention of aspiration pneumonia. Medline was searched from inception to November 2013. All descriptive or experimental studies that added to the understanding of aspiration pneumonia were reviewed. All studies that provided insight into the clinical aspiration syndromes, historical context, diagnosis, microbiology, risk factors, prevention, and treatment were summarized within the text. Despite the original teaching, aspiration pneumonia is difficult to distinguish from other pneumonia syndromes. The microbiology of pneumonia after a macroaspiration has changed over the last 60 years from an anaerobic infection to one of aerobic and nosocomial bacteria. Successful antibiotic therapy has been achieved with several antibiotics. Various risks for aspiration have been described leading to several proposed preventative measures. Aspiration pneumonia is a disease with a distinct pathophysiology. In the modern era, aspiration pneumonia is rarely solely an anaerobic infection. Antibiotic treatment is largely dependent on the clinical scenario. Several measures may help prevent aspiration pneumonia. Copyright © 2014 Elsevier Inc. All rights reserved.

    The purpose of this direct replication study was to confirm the incidence of vocal fold immobility (VFI) and its relationship to pharyngeal dysphagia and aspiration. Using a single-group consecutively referred case series, a total of 2,650 participants underwent fiberoptic endoscopic evaluation of swallowing between August 2003 and December 2007. Main outcome measures included overall incidence of VFI and aspiration status, with specific emphasis on age, gender, etiology and pharyngeal phase bolus flow characteristics, and side of VFI (right, left, or bilateral). These data were compared to and then combined with the original study (n = 1,452) for a total of 4,102 participants. Results indicated that the incidence of VFI was 4.3% (112/2,650), i.e., 27% (31/112) unilateral right, 58% (65/112) unilateral left, and 14% (16/112) bilateral. Incidence of aspiration was 22% (580/2,650). Of those with VFI, 40% (45/112) aspirated, i.e., 42% (13/31) unilateral right, 37% (24/65) unilateral left, and 50% (8/16) bilateral. An individual with VFI had 2.50 times the odds of aspirating as someone without VFI (95% CI = 1.86-3.37). For liquid aspiration, the odds ratio (OR) = 2.41 (95% CI = 1.77-3.28), and for puree aspiration, OR = 2.08 (95% CI = 1.47-2.93). Left VFI occurred most frequently due to surgical trauma. Liquid was aspirated more often than a puree. Males exhibited VFI more often than females. Side of VFI and age were not factors that increased the incidence of aspiration significantly. It was confirmed that VFI is not an uncommon finding during dysphagia testing and, when present, increased the odds of aspiration compared to a population already being evaluated for dysphagia.

    To compare the frequency of recurrence following aspiration and injection of steroid versus surgical excision in the treatment of wrist ganglion. Study Design: Randomized controlled trial.Place and Duration of Study: General surgical department, Combined Military Hospital, Rawalpindi, Pakistan, from Jan 2010 to Dec 2010. Material and Methods: Sixty patients of clinically diagnosed wrist ganglia were randomized into groups 'A' and 'B' with 30 patients in each group. After approval by the hospital ethical committee, patients in group 'A' were subjected to aspiration and injection of methyl-prednisolone acetate 40 mg/ml and those in group 'B' underwent surgical excision of the ganglion. Patients were explained the procedure they were subjected to and they were also counselled about the risk of recurrence after a particular procedure and after that informed written consent was obtained from them. Patients were followed up at intervals of 2 weeks, 6 weeks, 3 months and 6 months after the procedure to look for recurrence in both groups. Results: On follow up at 6 months, 12 (40%) patients in group A while only 2 (6.66%) patients in group B had recurrence of the ganglion. No complications were noted. This difference was found to be statistically significant (p=0.0023). Conclusion: Recurrence of wrist ganglion is considerably less in patients treated with surgical excision and should be preferred over aspiration and steroid injection. (author)

    Full Text Available Coronary angiogram in a young man with history of STEMI with delayed presentation revealed subtotal occlusion of left anterior descending artery (LAD with large thrombotic filling defect distal to the critical lesion. PCI was preferred without delay because of ongoing chest pain. Several runs of thrombus aspiration failed to detect any visible thrombus. However, the immediate angiogram after thrombus aspiration showed complete distal embolization of the thrombus which could have been achieved by Dottering or balloon dilatation. In contrary to the general perception, does thrombus aspiration push more thrombus than it can aspirate?

    To understand the perceived utility of a novel simulator to improve operative skill, eye-hand coordination, and depth perception. We used the ImmersiveTouch simulation platform (ImmersiveTouch, Inc., Chicago, Illinois, USA) in two U.S. Accreditation Council for Graduate Medical Education-accredited neurosurgical training programs: the University of Chicago and the University of Texas Medical Branch. A total of 54 trainees participated in the study, which consisted of 14 residents (group A), 20 senior medical students who were neurosurgery candidates (group B), and 20 junior medical students (group C). The participants performed a simulation task that established bipolar hemostasis in a virtual brain cavity and provided qualitative feedback regarding perceived benefits in eye-hand coordination, depth perception, and potential to assist in improving operating skills. The perceived ability of the simulator to positively influence skills judged by the three groups: group A, residents; group B, senior medical students; and group C, junior medical students was, respectively, 86%, 100%, and 100% for eye-hand coordination; 86%, 100%, and 95% for depth perception; and 79%, 100%, and 100% for surgical skills in the operating room. From all groups, 96.2% found the simulation somewhat or very useful to improve eye-hand coordination, and 94% considered it beneficial to improve depth perception and operating room skills. This simulation module may be suitable for resident training, as well as for the development of career interest and skill acquisition; however, validation for this type of simulation needs to be further developed.

In 3 (7% of the patients, the treatment failed, where symptoms had not resolved after 3 days, with further pus collection despite aspiration and antibiotics, where surgical drainage was required. Conclusions: Percutaneous needle drainage of breast abscesses after preliminary breast US is feasible as a primary and definitive treatment for breast abscesses, if complete or near complete drainage is achieved.

    Direct combination of cavitron ultrasonic surgical aspirator (CUSA) and sonic spray ionization mass spectrometry is presented. A commercially available ultrasonic surgical device was coupled to a Venturi easy ambient sonic-spray ionization (V-EASI) source by directly introducing liquified tissue debris into the Venturi air jet pump. The Venturi air jet pump was found to efficiently nebulize the suspended tissue material for gas phase ion production. The ionization mechanism involving solely pneumatic spraying was associated with that of sonic spray ionization. Positive and negative ionization spectra were obtained from brain and liver samples reflecting the primary application areas of the surgical device. Mass spectra were found to feature predominantly complex lipid-type constituents of tissues in both ion polarity modes. Multiply charged peptide anions were also detected. The influence of instrumental settings was characterized in detail. Venturi pump geometry and flow parameters were found to be critically important in ionization efficiency. Standard solutions of phospholipids and peptides were analyzed in order to test the dynamic range, sensitivity, and suppression effects. The spectra of the intact tissue specimens were found to be highly specific to the histological tissue type. The principal component analysis (PCA) and linear discriminant analysis (LDA) based data analysis method was developed for real-time tissue identification in a surgical environment. The method has been successfully tested on post-mortem and ex vivo human samples including astrocytomas, meningeomas, metastatic brain tumors, and healthy brain tissue. © 2011 American Chemical Society

    Full Text Available Foreign body aspiration (FBA is common under 3 years of age. FBA can cause sudden respiratory failure. Furthermore, it leads to many respiratory system complications. Therefore, FBA is an important cause of mortality and morbidity for this age group. FBA cases are usually followed by diagnoses like pneumonia, bronchitis or bronchial asthma in the late period that history, clinical and laboratory findings suggesting foreign body aspiration can not be detected. We reported a 2-year-old male patient with pneumonia, who were administered various treatments. In thorax CT of this case, an image compatible with foreign body was seen in the right middle lobe-upper lobe separation area. Granulation tissue was detected in the entrance of the right main bronchus by rigid bronchoscopy and marked improvement occured in lung aeration after bronchoscopy. This case was reported to emphasize the importance of early diagnosis of foreign body aspiration because of high mortality and morbidity and the necessity of considering the foreign body aspiration in children with recurrent pulmonary infections.

    Proven as a time challenged and cost-effective sampling procedure, the use of FNAB has still remained controversial among the scientific community. Currently, other minimally invasive sampling procedures such as ultrasound guided fine needle aspiration biopsy (US-FNAB) and image guided core needle biopsy (IG-CNB) have become the preferred sampling procedures for evaluation of breast lesions. However, changes in the medical economy and the current growing emphasis on cost containment in the era of the Affordable Care Act make it necessary to stimulate a renewed interest in the use of FNAB as the initial diagnostic sampling procedure. This study was designed to define the changing trend in the practice of tissue sampling during the last several years, and to assess the comparative effectiveness and appropriateness of the procedure of choice for breast cancer diagnosis. After Institutional Review Board (IRB) approval, the computer database of the Pathology Department, University of Florida, College of Medicine-Jacksonville at UF Health was retrospectively searched to identify all breast biopsy pathology reports issued during the period of January 2004 to December 2011. The inclusion criteria were all women that underwent any of the following biopsy types: FNAB, US-FNAB, IG-CNB, and surgical biopsy (SB). Diagnostic procedures were identified using current procedural terminology (CPT) codes recorded on claims from the UF Health Jacksonville patient accounting application files. The data obtained was used to determine which technique has the best cost-effectiveness in the diagnosis of breast cancer. The outcome variable for this project was a positive breast cancer diagnosis resulting from these methodologies. The predictor variable was the biopsy type used for sampling. The rate of cancer detection for each procedure was also determined. Among the four groups of procedures compared, the lower cost was attributed to FNAB, followed by US-FNAB, and SB. IG-CNB was the most

    Full Text Available Fine-needle aspiration biopsy (FNA is usually applied to distinguish benign from malignant thyroid nodules. However, cytological analysis cannot always allow a proper diagnosis. We believe that the improvement of the diagnostic capability of pre-surgical FNA could avoid unnecessary thyroidectomy. In a previous study, we performed a proteome analysis to examine FNA collected after thyroidectomy. With the present study, we examined the applicability of these results on pre-surgical FNA. We collected pre-surgical FNA from 411 consecutive patients, and to obtain a correct comparison with our previous results, we processed only benign (n=114, papillary classical variant (cPTC (n=34 and papillary tall cell variant (TcPTC (n=14 FNA. We evaluated levels of five proteins previously found up-regulated in thyroid cancer with respect to benign nodules. ELISA and western blot (WB analysis were used to assay levels of L-lactate dehydrogenase B chain (LDHB, Ferritin heavy chain, Ferritin light chain, Annexin A1 (ANXA1, and Moesin in FNA. ELISA assays and WB analysis confirmed the increase of LDHB, Moesin, and ANXA1 in pre-surgical FNA of thyroid papillary cancer. Sensitivity and specificity of ANXA1 were respectively 87 and 94% for cPTC, 85 and 100% for TcPTC. In conclusion, a proteomic analysis of FNA from patients with thyroid nodules may help to distinguish benign versus malignant thyroid nodules. Moreover, ANXA1 appears to be an ideal candidate given the high sensitivity and specificity obtained from ROC curve analysis.

    Cervical auscultation (CA) may be used to complement feeding/swallowing evaluations when assessing for aspiration. There are no published pediatric studies that compare the properties of sounds between aspirating and nonaspirating swallows. To establish acoustic and perceptual profiles of aspirating and nonaspirating swallow sounds and determine if a difference exists between these 2 swallowing types. Aspiration sound clips were obtained from recordings using CA simultaneously undertaken with videofluoroscopic swallow study. Aspiration was determined using the Penetration-Aspiration Scale. The presence of perceptual swallow/breath parameters was rated by 2 speech pathologists who were blinded to the type of swallow. Acoustic data between groups were compared using Mann Whitney U-tests, while perceptual differences were determined by a test of 2 proportions. Combinations of perceptual parameters of 50 swallows (27 aspiration, 23 no aspiration) from 47 children (57% male) were statistically analyzed using area under a receiver operating characteristic (aROC), sensitivity, specificity, and positive and negative predictive values to determine predictors of aspirating swallows. The combination of post-swallow presence of wet breathing and wheeze and absence of GRS and normal breathing was the best predictor of aspiration (aROC = 0.82, 95% CI, 0.70-0.94). There were no significant differences between these 2 swallow types for peak frequency, duration, and peak amplitude. Our pilot study has shown that certain characteristics of swallow obtained using CA may be useful in the prediction of aspiration. However, further research comparing the acoustic swallowing sound profiles of normal children to children with dysphagia (who are aspirating) on a larger scale is required. © The Author(s) 2016.

    Blood damage caused by traditional vacuum-operated suction tubes, particularly when air is aspirated along with the blood, usually exceeds damage from all other components. In addition to platelet injury, there is a high degree of hemolysis, which leads to high plasma hemoglobin levels and reduces the number of red blood cells available for reinfusion during cases of blood conservation, such as autologous transfusion and cardiac bypass. This work was undertaken to minimize hemolysis, and the accompanying platelet destruction, during aspiration, with the design of a jet-driven aspirator that separates and removes air from blood immediately within the suction tip. The jet-driven aspirator can suction blood at a range of rates from 100 to at least 700 ml/min, separates and removes 80-100% of aspirated air, operates at any orientation, and generates subatmospheric pressures on the order of only 1 inch H2O. In-vitro hemolysis testing showed a significant reduction in average plasma hemoglobin release, from 19.4 mg/dl to 1.8 mg/dl, when air was removed during blood aspiration. In comparative testing with a conventional vacuum suction tube, the jet-driven aspirator showed significantly less hemolysis than the conventional aspirator at comparable rates of air and blood aspiration.

    Acute renal artery embolism (RAE) is a rare condition associated with significant morbidity and mortality. The treatment strategy for RAE includes anticoagulation with or without thrombolysis or surgical or endovascular embolectomy. We describe here a case presentation of acute RAE secondary to atrial fibrillation treated successfully with Penumbra Indigo Aspiration System, a novel device in peripheral endovascular interventions. Our patient had ongoing symptoms and acute renal failure on presentation with contraindication to thrombolysis given hypertensive emergency. A 6F Penumbra Aspiration catheter was used to aspirate large amounts of thrombus from segmental renal arteries with restoration of flow. Patient's symptoms and renal function returned to baseline after intervention. Penumbra system is used routinely in cerebral endovascular intervention, yet here we describe its potential use in peripheral vascular interventions in addition to a literature review of all available evidence for the different treatment modalities of acute RAE.

    To explore the clinicopathological characteristics of aspiration pneumonia in the elderly. The clinical data of 30 cases of autopsy-proven aspiration pneumonia in Beijing Hospital from 1973 to 2002 were reviewed. The patients consisted of 28 males and 2 females, aged from 63 to 103 [mean (83 ± 9)] years. Only 15 cases were clinically diagnosed as aspiration pneumonia before death. Concomitant diseases were severe and complex, mostly coronary disease, cerebrovascular disease, hypertension, COPD, and diabetes mellitus. All the patients suffered from at least 3 concomitant diseases. Long-term bedridden and nasogastric feeding was seen in 11 and 17 patients respectively. The clinical presentation and chest X-ray of aspiration pneumonia in the elderly were nonspecific and variable. Mixed infections were common . The main bacteria isolated were Gram-negative bacilli, in particular Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Escherichia coli and Candida albicans. By pathology, macrophages with foreign bodies were found in all the 30 cases and multiple small abscesses were found in 14 cases. The lesions were adjacent to the bronchioles and in the lung tissue around the bronchioles, mostly multi-lobar and bilateral. Unilateral or bilateral pleural effusion developed in 20 patients. The accordance between radiological and pathological diagnosis of aspiration pneumonia was very poor. The foci of infection detected by X-ray were proven by autopsy in 13 patients, while pleural effusions in X-ray were proven by autopsy in 15 patients. Multi-concomitant diseases, mixed infection and extra-pulmonary presentations were common in elderly patients with aspiration pneumonia. Multiple small abscesses were the pathological characteristics of aspiration pneumonia in the aged. A definite clinical diagnosis of aspiration pneumonia was difficult. Recurrent silent microaspiration was a feature of aspiration in the elderly. The assessment of risk factor of aspiration played an

    Aspiration pneumonias occur more frequently than reported and, in many cases, the disease is not recognised. In hospitalised and institutionalised patients with predisposing diseases prompt diagnosis of this complication and correct preventive measures can drastically reduce the worsening of clinical conditions and the deaths due to aspiration pneumonia. Normal airway structure, effective defence mechanisms, and preventive measures are decisive in reducing aspiration episodes. An increased aspiration risk for food, fluids, medications, or secretions may lead to the development of pneumonia. Pneumonia is the most common respiratory complication in all stroke deaths and in mechanical ventilation patients. In addition, the increased incidence of aspiration pneumonia with aging may be a consequence of impairment of swallowing and the cough reflex. Dysphagia, compromised consciousness, invasive procedures, anaesthesia, insufficient oral care, sleep disorders, and vomiting are all risk factors. Aspiration pneumonia includes different characteristic syndromes based on the amount (massive, acute, chronic) and physical character of the aspirated material (acid, infected, lipoid), needing a different therapeutic approach. Chronic patients education and correct health care practices are the keys for preventing the events of aspiration. In patients at risk a clinical and instrumental assessment of dysphagia should be evaluated. Management includes the removal of etiologic factors (drugs, tubes, mobilisation, oral hygiene), supportive care, and in bacterial pneumonias a specific antibiotic therapy for community-acquired or nosocomial events.

    Full Text Available Lung aspiration disorders in bovines are invariably diagnosed as infectious aspiration pneumonias. There is a distinct differentiation between aspiration pneumonia and aspiration pneumonitis in humans that can be applied to bovines. The nature and quantity of the aspirate can result in differing pathogeneses which can require differing therapeutic approaches. Whilst blood gases were important in detecting and prognosticating lung problems, changes in barometric pressure with altitude have to be considered when interpreting partial pressures of oxygen. Anatomical differences in the lungs of bovines can explain why this species is more prone to certain pneumonic problems. Pulmonary physiotherapy is important in treating lung disorders in humans and should be considered as an adjunct therapy in bovine respiratory conditions. A case work-up was used to highlight some of the points discussed in this article.

    2015-08-01

    Bone marrow aspirate and trephine (BMAT) biopsy is a commonly performed procedure in hematology-oncology practice. Although complications are uncommon, they can cause significant morbidity and mortality. Simulation models are an excellent tool to teach novice doctors basic procedural skills before performing the actual procedure on patients to improve patient safety and well-being. There are no commercial BMAT simulators, and this technical report describes the rationale, technical specifications, and construction of a low-cost, easily constructed, reusable BMAT simulator that reproduced the tactile properties of tissue layers for use as a teaching tool in our resident BMAT simulation course. Preliminary data of learner responses to the simulator were also collected. From April 2013 to November 2013, 32 internal medicine residents underwent the BMAT simulation course. Eighteen (56%) completed the online survey, 11 residents with previous experience doing BMAT and 7 without experience. Despite the difference in operative experience, both experienced and novice residents all agreed or strongly agreed that the model aided their understanding of the BMAT procedure. All agreed or strongly agreed that this enhanced their knowledge of anatomy and 16 residents (89%) agreed or strongly agreed that this model was a realistic simulator. We present a novel, low-cost, easily constructed, realistic BMAT simulator for training novice doctors to perform BMAT.

    The objective of this study is to determine the role of ne needle aspiration microbiology (FNAM) in detecting the causative organisms of postoperative surgical site infections (SSIs) in comparison with the standard technique of surface swabbing. Ma- terials and Methods. In this study, 150 patients with SSIs following elective and emergency operations were included. In all patients, FNAM was performed along with conventional surface swabbing to identify the causative microorganism. Sensitivity of surface swab and FNAM was calculated as the number of samples collected from the diagnosed case of SSI. A total of 115 positive cultures were obtained from the 150 patients with SSIs; surface swab was positive in 110 cases and FNAM was positive in 94 cases. The mean number of organisms isolated by surface swab, and FNAM was 0.95 and 0.8, respectively. The sensitivity of surface swab was 94.3% in elective cases and 96.25% in emergency cases. The sensitivity of FNAM was 82.8% in elective cases and 82.5% in emergency cases. The sensitivity and negative predictive value of FNAM and surface swab did not signi cantly differ in clean elective cases. The overall sensitivity of surface swab and FNAM was 95.65% and 81.7%, respectively. Comparing the antibiotic suscep- tibility pattern, no difference was observed when the same organ- ism was isolated by both methods, indicating that FNAM does not offer bene t over the conventional wound surface swab in detecting microorganisms in SSI in both elective and emergency surgeries. In certain cases with unexplained wound infections, FNAM can be used as an investigation to identify speci c pathogens not detected by conventional surface swab.

    A 80-year-old man developed impairment in his laryngeal movement, vocal fold fixation and severe misdeglutition after radiotherapy for laryngeal carcinoma. Despite of several surgical treatments for aspiration pneumonia, the misdeglutition did not cease because of the stiffness in his larynx until a laryngectomy was finally performed. The resected larynx showed marked fibrosis, and it was considered as a late complication of radiotherapy. The treatment course in this difficult case is discussed. (author)

    Spontaneous infarction of fibroadenoma is an extremely rare complication in a nonpregnant/nonlactating female undergoing first-time aspiration. It can be misdiagnosed as carcinoma in all aspects of triple approach used for evaluation of patients with breast lesions. A 37-year-old woman presented to the outpatient surgical clinic with a 6-month history of a breast lump that was slowly increasing in size and had become painful during the past month. There was no history of any trauma or fine needle aspiration, and she was not pregnant or lactating. Mammogram and ultrasound revealed a 2.9-cm heterogenous hypoechoic suspicious lesion. No lymph nodes were detected in the axilla. Fine needle aspiration cytology was performed, and a diagnosis of benign breast lesion with features of infarction was rendered on cytology. The lump was excised surgically, and a histological diagnosis of infarcted fibroadenoma was made. Careful and diligent search for preserved benign epithelial cells on smears is the key to recognize this entity and avoid serious therapeutic implications.

    Ultrasonic aspiration is widely used in the resection of brain tumors. Nevertheless, tumor tissue fragments obtained by ultrasonic aspiration are usually discarded. In this study, we demonstrate that these fragments are possible sources of material for histopathological study and tissue culture and compare their microscopic features and viability in tissue culture of cavitron ultrasonic surgical aspirator tissue fragments. Brain tumor tissue collected by ultrasonic aspiration (CUSA EXcel®; Integra Radionics Inc.) in a simple sterile suction trap during resection was processed for primary cell culture. Cell viability and immunohistological markers were measured by the WST-1 test, microscopy and immunofluorescent evaluation. Six gliomas are presented to demonstrate that these tissue fragments show good preservation of histological detail and tissue viability in culture. Utilization of this material may facilitate pathological interpretation by providing a more representative sample of tumor histology as well as an adequate and sterile biosource of material for tissue culture studies.

    2016-06-01

    We report a case of a 33-year-old woman with depression and suicidal ideation, treated successfully with electroconvulsive therapy (ECT) in the past. Since her previous course of ECT, she underwent gastric banding, a bariatric surgical procedure associated with increased risk of gastric regurgitation. Despite increasingly stringent measures to minimize the risk of regurgitation and aspiration during ECT, she had several episodes of regurgitation, the last of which precipitated an acute illness consistent with aspiration pneumonitis. We took additional precautions after each event, until she had no further episodes of regurgitation. We discuss the risk posed by the gastric band, the measures we implemented to minimize that risk, and our recommendations for assessment and management of post-gastric banding patients who present for ECT.

    deterioration was seen in the other 2. Aspiration from solitary small cavitary lesions showed a relatively high number of NTM colonies. Pneumothorax was the only complication of the aspiration procedure. If the diagnostic criteria for pulmonary NTM diseases include positive culture in percutaneous aspiration material, the diagnosis of solitary nodular NTM lesions would become easier; at present, these lesions are often diagnosed only upon surgical resection. Further, clinical studies on the possibility of spontaneous shrinkage of the solitary lesion and the value of its medical treatment would be promoted. Aspiration can easily differentiate NTM disease from pulmonary abscess or fungal infection in patients with a solitary lesion or small cavity.

    Full Text Available Context: Dysplastic changes are well documented in myelodysplastic syndromes (MDS. However, they are also observed in non-MDS hematological conditions. Aims: To evaluate the megakaryocytic alterations in the bone marrow aspirations in cases of non-MDS related thrombocytopenia. Setting and Design: A prospective study of 144 bone marrow aspirates was conducted in the department of pathology, Kasturba Medical College, Mangalore. The aspirates were studied to assess the number and morphology of the megakaryocytes in non-MDS related thrombocytopenia and evaluate their significance when compared to changes in MDS. Materials and Methods: The bone marrow aspiration smears were stained with Leishman stain and examined under light microscope. Statistical Analysis Used: Fisher′s exact test. A P value less than 0.05 was considered significant. Sensitivity and specificity was calculated for those features which were significant in the relevant hematological disorders. Results: The sensitivity of immature megakaryocytes, dysplastic forms and micromegakaryocytes in cases of immune thrombocytopenic purpura was 100%, 89% and 42% respectively. The specificity of emperipolesis was 74%. In cases of infection-associated thrombocytopenia, immature megakaryocytes had a sensitivity of 100% and cytoplasmic vacuolization were 86% specific. The sensitivity of the dysplastic forms in megaloblastic anemia was 75%. However, no platelet budding was observed. The presence of micromegakaryocyte had a specificity of 83% in MDS, and was statistically significant when compared to cases of non-MDS conditions (P< 0.05. Conclusions: Careful understanding of the morphological changes of megakaryocytes in bone marrow aspirates can improve the diagnostic accuracy for a wide range of hematological disorders thereby enabling proper therapeutic interventions.

  6. Housing aspiration in an informal urban settlement: A case study

    Full Text Available Housing aspiration is an important aspect of housing market analysis. However, there is a paucity of empirical research on housing aspiration among residents in informal settlements in developing countries. This study therefore investigated housing aspiration among the residents of Ayobo, Lagos, Nigeria. A cross-sectional survey of 1,151 households in Ayobo was conducted using a structured questionnaire as the data-collection instrument. The data were analysed using descriptive statistical and categorical regression analyses. The results show that a majority of the respondents were low-income earners living in rented and rooming-house types of accommodation. Around 73% of them expressed an intention to move to another residence, and 56% of this category of respondents intend to move into self-contained flats. The reasons for the planned relocation include poor condition of their present dwellings, changes in tenure status and household size, and the desire for exclusive use of facilities in their homes. In addition to these reasons, the waste-disposal method, sharing facilities, employment, and age and marital status of the residents emerged as the strongest predictors of housing aspiration among the respondents in the survey. This implies that, in order to meet the housing preferences and aspirations of residents in informal urban settlements in Nigeria, housing developers need to give adequate attention to the marital, age, employment and tenure status of the residents and place emphasis on developing affordable single-family houses and block of flats, as well as strategies for improving access to basic social amenities and services.

    This case reports describes a 39-year-old female with a history of surgically repaired hypoplastic left heart syndrome who presented with a left peripherally inserted central catheter (PICC) with associated large volume subclavian and brachiocephalic vein thrombus. Due to the presence of a right-to-left shunt via a fenestrated Fontan, there was clinical concern for a paradoxical embolism during removal of the PICC. The AngioVac aspiration system was successfully utilized to aspirate thromboemboli from the level of the proximal Glenn shunt during manipulation and removal of the PICC. This is the first reported case to demonstrate the safe and effective use of the AngioVac aspiration system for protection of paradoxical emboli through a cardiac right-to-left shunt during a procedure at high risk for thromboembolism.

    Olecranon bursitis might be a minor problem in the outpatient clinic but relatively be common to occur. However, there are few well-designed studies comparing approaches to treatment. (1) Which treatment (compression bandaging with nonsteroidal antiinflammatory drugs [NSAIDs], aspiration, or aspiration with steroid injections) is associated with the highest likelihood of resolution of nonseptic olecranon bursitis? (2) Which treatment is associated with earliest resolution of symptoms? (3) What factors are associated with treatment failure by 4 weeks? We enrolled 133 patients from two centers; after applying prespecified exclusions (septic bursitis or concomitant inflammatory arthritis, intraarticular elbow pathology, recent aspiration or steroid injection done elsewhere, and refusal to participate), 90 patients were randomly allocated to receive compression bandaging with NSAIDs (C), aspiration (A), or aspiration with steroid injection (AS) groups (30 patients in each). The groups were similar at baseline in terms of age and gender. Seven patients (four from Group A and three from Group AS) were lost to followup. All patients were followed up weekly for 4 weeks, and the same treatment procedure was repeated if the bursitis recurred with any substantial fluid collection. At 4 weeks, the state of resolution and pain visual analog scale (VAS) were evaluated. Failed resolution was defined as presence of persistent olecranon bursal fluid collection at Week 4 after the initiation of the treatment; on the contrary, if bursal fluid collection was clinically reduced or completely disappeared by the end of Week 4, the treatment was considered successful. We compared the proportion of resolution by Week 4 and the median times to resolution among the treatment groups. In addition, we evaluated whether the resolution affected pain VAS and what factors were associated with the resolution. There were no differences in the proportion of patients whose bursitis resolved by Week 4

    A 30-year-old female presented with a three-month history of a multilocular cystic lesion over the lumbosacral spine. Fine-needle aspiration biopsy (FNA) of the lesion was performed at an outside institution, and a cytologic diagnosis, suspicious for chordoma, was rendered. The patient presented for surgical consultation at our institution. Repeat FNA demonstrated an unusual fat-like material. Upon further inquiry, the patient provided a recent history of gluteal contour improvement with fibroadipose tissue implants. A diagnosis of myospherulosis was made with a concurrent surgical pathology correlation. No evidence of chordoma was identified. To date, this is the first reported case of acquired myospherulosis in the context of gluteal contour enhancement and represents an important diagnostic pitfall to consider on cytology preparations. © 2017 Wiley Periodicals, Inc.

    Non-toxic aqueous foams are being developed by Sandia National Laboratories (SNL) for the National Institute of Justice (NIJ) for use in crowd control, cell extractions, and group disturbances in the criminal justice prison systems. The potential for aspiration of aqueous foam during its use and the resulting adverse effects associated with complete immersion in aqueous foam is of major concern to the NIJ when examining the effectiveness and safety of using this technology as a Less-Than-Lethal weapon. This preliminary study was designed to evaluate the maximum quantity of foam that might be aspirated by an individual following total immersion in an SNL-developed aqueous foam. A.T.W. Reed Breathing simulator equipped with a 622 Silverman cam was used to simulate the aspiration of an ammonium laureth sulfate aqueous foam developed by SNL and generated at expansion ratios in the range of 500:1 to 1000:1. Although the natural instinct of an individual immersed in foam is to cover their nose and mouth with a hand or cloth, thus breaking the bubbles and decreasing the potential for aspiration, this study was performed to examine a worst case scenario where mouth breathing only was examined, and no attempt was made to block foam entry into the breathing port. Two breathing rates were examined: one that simulated a sedentary individual with a mean breathing rate of 6.27 breaths/minute, and one that simulated an agitated or heavily breathing individual with a mean breathing rate of 23.7 breaths/minute. The results of this study indicate that, if breathing in aqueous foam without movement, an air pocket forms around the nose and mouth within one minute of immersion.

    Riedel thyroiditis is a rare fibrosing disorder characterized by extension of the fibroinflammatory process beyond the thyroid capsule. Due to the nature of this lesion, fine-needle aspiration often yields scant material and may be interpreted as non-diagnostic. In this report, we describe cytologic features that allow the cytopathologist to favor a diagnosis of Riedel thyroiditis, thereby guiding appropriate further work-up and management. © 2015 Wiley Periodicals, Inc.

  16. Stereotactic aspiration versus craniotomy for primary intracerebral hemorrhage: a meta-analysis of randomized controlled trials.

    Directory of Open Access Journals (Sweden)

    Jia-Wei Wang

    Full Text Available BACKGROUND: A wealth of evidence based on the randomized controlled trials (RCTs has indicated that surgery may be a better choice in the management of primary intracerebral hemorrhage (ICH compared to conservative treatment. However, there is considerable controversy over selecting appropriate surgical procedures for ICH. Thus, this meta-analysis was performed to assess the effects of stereotactic aspiration compared to craniotomy in patients with ICH. METHODS: According to the study strategy, we searched PUBMED, EMBASE and Cochrane Central Register of Controlled Trials. Other sources such as the internet-based clinical trial registries, relevant journals and the lists of references were also searched. After literature searching, two investigators independently performed literature screening, assessment of quality of the included trials and data extraction. The outcome measures included death or dependence, total risk of complication, and the risk of rebleeding, gastrointestinal hemorrhage and systematic infection. RESULTS: Four RCTs with 2996 participants were included. The quality of the included trials was acceptable. Stereotactic aspiration significantly decreased the odds of death or dependence at the final follow-up (odds ratio (OR: 0.80, 95% confidence interval (CI: 0.69-0.93; P = 0.004 and the risk of intracerebral rebleeding (OR: 0.44, 95% CI: 0.26-0.74; P = 0.002 compared to craniotomy with no significant heterogeneity among the study results. CONCLUSIONS: The present meta-analysis provides evidence that the stereotactic aspiration may be associated with a reduction in the odds of being dead or dependent in primary ICH, which should be interpreted with caution. Further trials are needed to identify those patients most likely to benefit from the stereotactic aspiration.

    Full Text Available Chordomas are primary low grade malignant tumors of bone that usually arise within both ends of axial skeleton. The Notochord is a midline, ectoderm-derived structure that defines the phylum of chordates. Chordomas may pose difficult diagnostic challenges when encountered in secondary locations, such as lungs or other parenchymatous organs. We report the cytologic findings of a metastatic chordoma sampled through CT-scan guided fine needle aspiration (FNA of lower lobe lung nodule in a 54-year-old man diagnosed with recurrent chordoma involving the lumber spine and paraspinal region.

    A 51-year-old female who presented with obstructive jaundice was found to have masses in the pancreatic head and tail as well as suspicious liver and periaortic masses on imaging. Aspiration cytology of the pancreatic tail mass showed abundant large single cells with vacuolated eosinophilic cytoplasm, marked nuclear pleomorphism, large bizarre irregular nuclei, binucleation, and prominent nucleoli. Numerous cells also showed intracytoplasmic black to brown pigmentation. A cell block was obtained and extensive immunohistochemical staining was performed. S-100, HMB-45, Sox10, pancytokeratin, CK7, RCC antigen, synaptophysin, HepPar 1, inhibin, CD45, CD21, and CD123 were negative, making melanoma, epithelial malignancies, lymphoma, follicular dendritic and plasmacytoid dendritic cell neoplasms less likely. CD4 and CD56 showed partial positivity, and CD68, CD163, and CD14 were positive, supporting the diagnosis of histiocytic sarcoma. Surgical specimens and immunohistochemistry confirmed the cytologic findings. Histiocytic sarcoma is a rare aggressive malignancy of histiocytic origin with most cases presenting in adults in extranodal sites, most commonly the intestinal tract. Few cases are reported in the literature, presenting diagnostic challenges for cytopathologists when seen on fine-needle aspiration. We present the first reported case of histiocytic sarcoma presenting as a pancreatic mass, diagnosed by endoscopic ultrasound guided fine-needle aspiration (EUS-FNA). This entity is rarely described on cytology and arose in a location in which EUS-FNA is the diagnostic modality of choice. This case study highlights that cytopathologists should be aware of histiocytic sarcoma occurring in extranodal locations accessible by EUS-FNA and be familiar with the cytomorphologic appearance. © 2017 Wiley Periodicals, Inc.

  20. Fine needle aspiration biopsy diagnosis of metastatic neoplasms of the breast. A three-case report

    Full Text Available Abstract Metastases to the breast are unusual lesions that make up approximately 2% of all malignant mammary neoplasms and may mimic both benign and malignant primary neoplasms from a clinical point of view, as well as in imaging studies. Arriving at a correct diagnosis is therefore essential in order to establish appropriate management. We present three cases of metastatic neoplasms diagnosed through fine needle aspiration biopsy and immunocytochemistry. The cytological diagnoses were: medulloblastoma in an 18-year-old woman, melanoma in a 26-year-old man, and an exceptional case of ovarian sarcoma originating from a granulosa cell tumor with metastases to both breasts. A metastatic disease should be considered in the differential diagnosis of a palpable mass in the breast, especially if there is a history of an extramammary malignant neoplasm. Fine needle aspiration biopsy is the method of choice for the management of these cases. Whenever possible the exam of the material obtained should be compared to the previous biopsy, which is usually enough to arrive at a correct diagnosis, thus preventing unnecessary surgical procedures.

    Full Text Available Background: Foreign body aspiration (FBA is a common cause of respiratory compromise in early childhood. The objective of this study was to describe the features and outcomes of children with FBA in early and late presentations and to examine the reasons for the delay in diagnosis. Patients and Methods: This is a retrospective review of all children who were admitted with suspected FBA between July 2001 and June 2010. Patient′s characteristics, history, clinical, radiographic, bronchoscopic findings, reason for delay presentation, and complications were noted. Results: A total of 158 children admitted to the hospital with suspected FBA were included in this study. The average age was 3.28 years. Forty-eight (30.3% children were presented late (more than 14 days after FBA and 110 (69.7% children were presented early (0-14 days. The common clinical manifestations of FBA were persistent cough (100% and choking (72%. The most frequent radiological finding observed was air trapping (40% followed by atelectasis (14%. Chest radiographs were normal in 32.2% patients. Ten children in early diagnosis group and 29 children in late diagnosis group presented with complications. The diagnosis delay was mainly attributed to physician misdiagnosis (41.6%. Rigid bronchoscopy was performed in all patients. Foreign body was found in all of the cases except six. Watermelon seeds and peanuts accounted for 80% of the aspiration. Conclusion: FBA is difficult to diagnose in children. Delay in diagnosis appears to result from a failure to give serious consideration to the diagnosis. Early diagnosis and removal of foreign bodies must be achieved to avoid complications.

  5. The NHS as a learning organization: aspirations beyond the rainbow?

    Science.gov (United States)

    Timpson, J

    1998-09-01

    It is the intention of this paper to review the issues and challenges organizations face when aspiring to embrace and enact the tenets of a learning organization; and in particular the perceived impact on management strategy, structure and leadership styles. The paper is predicated on the premise that learning and knowledge act as vital strategic resources, crucial not only to organizations in terms of competitive advantage but to ethical enterprise per se. Modern life is characterized by change, against the backdrop of this continual turmoil, organizational learning has emerged as a dominant theme within contemporary management theory, with many commentators increasingly locating the capacity of an aspiring organization to accommodate the ethos of organizational learning, as the vital component in ensuring enduring efficiency, innovation and competitiveness. However, the utility of such learning needs to be scrutinized and evaluated in terms of service need and expectation. The paper will expand upon wider theoretical debates extant within the literature, by considering the concept and utility of the learning organization with specific reference to management reform extant within the British National Health Service (NHS). During the course of the review the various the theoretical positions contributing to the notion of the learning organization will be analysed, the practical ramifications of which will be examined in the context of reflective practice, clinical supervision and the wider cultural background of nursing and the NHS. The paper concludes that the NHS needs to reorientate management perspectives to focus attention more acutely on systems which are deliberately designed to facilitate shared learning, to unravel the ambiguities of organizational life, to affirm management belief in the nursing contribution and to achieve an as yet unrealized potential in terms of patient care and advanced nursing practice.

    Though open surgical biopsy is the procedure of choice for the diagnosis of bone tumors, many disadvantages are associated with this approach. The present study was undertaken to evaluate the role of fine needle aspiration cytology (FNAC) as a diagnostic tool in cases of bony tumors and tumor-like lesions which may be conducted in centers where facilities for surgical biopsies are inadequate. The study population consisted of 51 cases presenting with a skeletal mass. After clinical evaluation, radiological correlation was done to assess the nature and extent of each lesion. Fine needle aspiration was performed aseptically and smears were prepared. Patients subsequently underwent open surgical biopsy and tissue samples were obtained for histopathological examination. Standard statistical methods were applied for analysis of data. Adequate material was not obtained even after repeated aspiration in seven cases, six of which were benign. Among the remaining 44 cases, diagnosis of malignancy was correctly provided in 28 (93.3%) out of 30 cases and categorical diagnosis in 20 (66.67%). Interpretation of cytology was more difficult in cases of benign and tumor-like lesions, with a categorical opinion only possible in seven (50%) cases. Statistical analysis showed FNAC with malignant tumors to have high sensitivity (93.3%), specificity (92.9%) and positive predictive value of 96.6%, whereas the negative predictive value was 86.7%. FNAC should be included in the diagnostic workup of a skeletal tumor because of its simplicity and reliability. However, a definitive pathologic diagnosis heavily depends on compatible clinical and radiologic features which can only be accomplished by teamwork. The cytological technique applied in this study could detect many bone tumors and tumor-like conditions and appears particularly suitable as a diagnostic technique for rural regions of India as other developing countries.

    6% of all patients suffering from a cerebro-vascular injury die from aspiration pneumonia within the first year. The high temporal resolution of high-speed cineradiography (HFK) (50 frames/sec.) allows the recording of the 0.7 sec. process of pharyngeal swallow. Five case-examples are presented (total number of cases: 95) illustrating the possibility of differentiation between three types of aspiration by means of cineradiography. These types are the so-called pre-, intra- and postdeglutitive aspiration, that is aspiration before or after triggering of the swallowing reflex. This differentiation is of great therapeutic importance. The analysis of disturbances of pharyngo-laryngeal motility and the temporal coordination allows setting up individual surgical and/or conservative programme for rehabilitation. (orig.) [de

    Full Text Available Abstract Three men and 2 women with ages ranging from 37 to 70 years, clinically and histologically confirmed solitary, palpable metastatic cancers to the thyroid (SMCT and preoperative cytologic investigation of their thyroid lesions by fine-needle aspiration (FNA, were reviewed. Four patients were known to have a solid cancer treated by radical surgery 1 to 4 years prior [1 bronchogenic squamous cell carcinoma, 1 parotid adenoid cystic carcinoma, 1 renal cell carcinoma (RCC and 1 cutaneous melanoma], and 1 patient had no past history of cancer. Direct smears prepared from the patients' thyroid FNAs were fixed in 95% ethanol and stained with the Papanicolaou method. In 3 cases, immunostaining of the aspirated tumor cells with thyroglobulin antibody was performed, and in 1 case an aspiration smear was stained with commercial HMB-45 antibody. A correct cytodiagnosis of metastatic cancer to the thyroid was made in all 5 cases. In 1 patient the thyroid FNA revealed a metastatic RCC that led to the discovery of a clinically occult RCC. All 5 patients died of metastatic disease 27 to 40 months after surgical resection of their SMCTs.

    To establish predictive models for late objective aspiration and late patient-reported choking based on dose-volume parameters and baseline patient and treatment characteristics, for patients with head and neck cancer undergoing definitive radiotherapy (RT). The impact of electively treated volume on late aspiration was also investigated. This prospective cohort is a subsample of 124 survivors from the ARTSCAN study. Late aspiration was identified with videofluoroscopy, at a minimum of 25months after the start of RT. Patient-reported choking was analysed at 12 and 60months post RT using the EORTC Quality of Life Module for Head and Neck Cancer 35. Univariable and multivariable analyses were performed to describe the association between clinical factors and dose-volume descriptors for organs at risk (OARs) and late dysphagia. Aspiration was found in 47% of the eligible patients. Mean dose to the middle pharyngeal constrictor (MPC), neck dissection post RT and age at randomisation in ARTSCAN were associated to late aspiration. Mean dose to the superior pharyngeal constrictor (SPC) and swallowing complaints at baseline were associated to patient reported choking at both time-points. Three separate risk groups for late aspiration, and two risk groups for late patient-reported choking were identified based on number of risk factors. The size of the electively treated volume could be used as a surrogate for individual OARs predicting late aspiration. Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.

    A perspective study was carried out to assess the efficacy of a combination of percutaneous aspiration plus oral albendazole to assess its efficacy as an alternative to surgery in the treatment of hydatid cyst. We performed percutaneous aspiration followed by injection of 20% hypertonic saline solution into 16 hydatid cysts in 13 patients. All the patients received oral albendazole (400 mg/12 hours) starting 2 days before and lasting until there weeks after the procedure. There were no anaphylactic reactions during or after the procedure. Follow-up included monthly ultrasound over a period ranging between 10 and 36 months. Three cysts disappeared completely; in 10 cases, the cysts cavity was replaced by a complex ultrasonographic findings, with strong signals similar to those of a pseudotumor. In another case, the aspirate was sterile and its morphology remained unchanged. In two cases, infection of the cyst ensued, requiring surgical treatment. We consider that percutaneous aspiration in combination with albendazole may prove to be a good alternative to surgery for the management of hepatic hydatid disease. (Author) 15 refs

    Maria L Odland

    Full Text Available OBJECTIVES: To investigate the use of manual vacuum aspiration in postabortion care in Malawi between 2008-2012. METHODS: A retrospective cross-sectional study was done at the referral hospital Queen Elisabeth Central Hospital, and the two district hospitals of Chiradzulu and Mangochi. The data were collected simultaneously at the three sites from Feb-March 2013. All records available for women admitted to the gynaecological ward from 2008-2012 were reviewed. Women who had undergone surgical uterine evacuation after incomplete abortion were included and the use of manual vacuum aspiration versus sharp curettage was analysed. RESULTS: Altogether, 5121 women were included. One third (34.2% of first trimester abortions were treated with manual vacuum aspiration, while all others were treated with sharp curettage. There were significant differences between the hospitals and between years. Overall there was an increase in the use of manual vacuum aspiration from 2008 (19.7% to 2009 (31.0%, with a rapid decline after 2010 (28.5% ending at only 4.9% in 2012. Conversely there was an increase in use of sharp curettage in all hospitals from 2010 to 2012. CONCLUSION: Use of manual vacuum aspiration as part of the postabortion care in Malawi is rather low, and decreased from 2010 to 2012, while the use of sharp curettage became more frequent. This is in contrast with current international guidelines.

    Fine-needle aspiration (FNA) has proven to be a safe and reliable method of investigation of thyroid lesions. Referencing to European classification, the associated risk of malignancy for TIR3, category reserved for aspirates that contain architectural and/or nuclear atypia, is variable in such studies. Aims of study were evaluating safety of surgical approach, assessing perioperative parameters surgically related, and estimating neoplastic rate for TIR3 group. A prospective evaluation of all TIR3 submitted to thyroidectomy was conducted by assessing histopatohologic results between January 2005 and December 2012, considering two categories, positive (neoplastic) and negative (not neoplastic) group. Intraoperative and complication rate was analyzed on TIR3 population. A total of 1514 total thyroidectomy was performed from 2005 to 2012: a total of 148 cases was considered on TIR3 group. Positive cases amounted to 64 (43.2%), 29 of which were carcinoma (19.6% of total population) and 35 of which were adenoma, while negative cases amounted to 84 (56.8%). Sensitivity and specificity of TIR3 as neoplastic screening was 43.2% and 82.1%. A total of 32 linfectomies was performed (21.6% of group). Positive group presented a significant lower mean age than negative group (42.1 vs 56.2 years) TIR3 group represents a various category, with probably different malignancy risk. Our results and neoplasms rate confirmed that surgical option should be gold standard, in order to define atypical pattern and reduce delayed diagnoses. Choice of a second FNA or a imaging monitoring should be adopted for specific condition. Fine-needle aspiration, Thyroidectomy, TIR3, Thyroid cancer.

    Full Text Available Foreign body aspiration is an urgent condition that requires immediate diagnosis and intervention. It is generally seen in children and in elderly patients with neurological problems and rarely seen in healthy adults. There may be some clinical signs and symptoms in patients with foreign body aspiration from mild to severe; such as cough, shortness of breath and respiratory arrest. A 52-year-old woman applied to our clinic with the complaints of cough and shortness of breath, and she was misdiagnosed and treated as asthma for three months. The chest radiograph showed heterogenous opacity in the right paracardiac region, computerized tomography revealed the foreign body aspiration in right main bronchus and peripheric pneumonia. Flexible bronchoscopy examination was processed and the foreign body was excluded safely with the aim of crocodile forceps. Foreign body aspiration should be kept in the mind in a adult patient with a sudden onset of asthma like disorder.

  1. Recurrent Aspiration Pneumonia due to Anterior Cervical Osteophyte

    Directory of Open Access Journals (Sweden)

    Jae Jun Lee

    2017-02-01

    Full Text Available A 74-year-old man presented with recurrent vomiting and aspiration pneumonia in the left lower lobe. He entered the intensive care unit to manage the pneumonia and septic shock. Although a percutaneous endoscopic gastrostomy tube was implanted for recurrent vomiting, vomiting and aspiration recurred frequently during admission. Subsequently, he complained of neck pain when in an upright position. A videofluoroscopic swallowing study showed compression of the esophagus by cervical osteophytes and tracheal aspiration caused by an abnormality at the laryngeal inlet. Cervical spine X-rays and computed tomography showed anterior cervical osteophytes at the C3-6 levels. Surgical decompression was scheduled, but was cancelled due to his frailty. Unfortunately, further recurrent vomiting and aspiration resulted in respiratory arrest leading to hypoxic brain damage and death. Physicians should consider cervical spine disease, such as diffuse skeletal hyperostosis as an uncommon cause of recurrent aspiration pneumonia.

    To compare outcomes using the novel portable endoscopy with that of nasogastric (NG) aspiration in patients with gastrointestinal bleeding. Patients who underwent NG aspiration for the evaluation of upper gastrointestinal (UGI) bleeding were eligible for the study. After NG aspiration, we performed the portable endoscopy to identify bleeding evidence in the UGI tract. Then, all patients underwent conventional esophagogastroduodenoscopy as the gold-standard test. The sensitivity, specificity, and accuracy of the portable endoscopy for confirming UGI bleeding were compared with those of NG aspiration. In total, 129 patients who had GI bleeding signs or symptoms were included in the study (age 64.46 ± 13.79, 91 males). The UGI tract (esophagus, stomach, and duodenum) was the most common site of bleeding (81, 62.8%) and the cause of bleeding was not identified in 12 patients (9.3%). Specificity for identifying UGI bleeding was higher with the portable endoscopy than NG aspiration (85.4% vs 68.8%, P = 0.008) while accuracy was comparable. The accuracy of the portable endoscopy was significantly higher than that of NG in the subgroup analysis of patients with esophageal bleeding (88.2% vs 75%, P = 0.004). Food material could be detected more readily by the portable endoscopy than NG tube aspiration (20.9% vs 9.3%, P = 0.014). No serious adverse effect was observed during the portable endoscopy. The portable endoscopy was not superior to NG aspiration for confirming UGI bleeding site. However, this novel portable endoscopy device might provide a benefit over NG aspiration in patients with esophageal bleeding.

    To compare surgical peeling and aspiration and neodymium yttrium garnet laser capsulotomy for pearl form of posterior capsule opacification (PCO). A prospective, randomized, double blind, study was done at Rotary Eye Hospital, Maranda, Palampur, India, Santosh Medical College Hospital, Ghaziabad, India and Laser Eye Clinic, Noida India. Consecutive patients with pearl form of PCO following surgery, phacoemulsification, manual small incision cataract surgery and conventional extracapsular cataract extraction (ECCE) for age related cataract, were randomized to have peeling and aspiration or neodymium yttrium garnet laser capsulotomy. Corrected distance visual acuity (CDVA), intra-operative and post-operative complications were compared. A total of 634 patients participated in the study, and 314 (49.5%) patients were randomized to surgical peeling and aspiration group and 320 (50.5%) to the Nd:YAG laser group. The mean pre-procedural logMAR CDVA in peeling and neodymium: yttrium-aluminium-garnet (Nd:YAG) laser group was 0.80±0.25 and 0.86±0.22, respectively. The mean final CDVA in peeling group (0.22±0.23) was comparable to Nd:YAG group (0.24±0.28; t test, P=0.240). There was a significant improvement in vision after both the procedures (Ppeeling group (262/83.4%) had a CDVA of 0.5 (20/63) or better at 9mo (Ppeeling group (25/7.7% vs 15/4.7%, respectively). On application of ANCOVA, there was less than 0.001% risk that PCO thickness and total laser energy had no effect on rate of complications in Nd:YAG laser group and less than 0.001 % risk that PCO thickness had no effect on complications in peeling group respectively. Sum of square analysis suggests that in the Nd:YAG laser group, thick PCO had a stronger impact on complications (Fischer test probability, Prpeeling group, thick PCO and preoperative vision had a stronger effect on complications than thin PCO, respectively (Fischer test probability, Prpeeling group. Retinal detachment was more common in patients

    The current trend in minimally invasive surgery is to make a small surgical incision. However, the excessive tensile stress applied by the retractors to the skin surrounding the incision often results in a long wound healing time and extensive scarring. To minimize these types of wound problems, the authors evaluated a simple and cost-effective method to minimize surgical incision scars based on the use of a latex surgical glove. The tunnel-shaped part of a powder-free latex surgical glove was applied to the incision and the dissection plane. It was fixed to the full layer of the dissection plane with sutures. The glove on the skin surface then was sealed with Ioban (3 M Health Care, St. Paul, MN, USA) to prevent movement. The operation proceeded as usual, with the retractor running through the tunnel of the latex glove. It was possible to complete the operation without any disturbance of the visual field by the surgical glove, and the glove was neither torn nor separated by the retractors. The retractors caused traction and friction during the operation, but the extent of damage to the postoperative skin incision margin was remarkably less than when the operation was performed without a glove. This simple and cost-effective method is based on the use of a latex surgical glove to protect the surgical skin incision site and improve the appearance of the postoperative scar.

    Pulmonary lavage - a supplementary measure of resuscitation in newborn infants with severe aspiration of meconium stained amniotic fluid. During 1984-1985 150 mature newborn infants who had aspirated heavily-stained or pea soup-like amniotic fluid were resuscitated at the University Hospital of Obstetrics and Gynaecology in Graz. In 109 of these infants (controls) routine aspiration of both the upper and lower airways was accomplished as soon as possible, whilst in the remaining 41 infants (lavaged) pulmonary lavage with saline was additionally performed via an endotracheal tube after aspiration to clear the trachea and the upper bronchi from thick meconium which could not have been removed as efficiently otherwise. The incidence of manifest meconium aspiration syndrome was significantly higher (22%) in the lavaged infants than in the controls (8%). Mechanical ventilation was performed in 36% of the lavaged infants, whereas only 5.5% of the controls had to be ventilated for more than 1 hour. The mean duration of ventilation, however, was shorter (Mh = 5.1 hrs vs Mh = 69 hrs) and the average age at discharge lower in the lavaged. Three infants died, two of whom had severe malformations. Only one death in the lavaged infants was attributable to severe meconium aspiration syndrome already manifest at birth. Three infants (two lavaged, one control) showed radiological evidence of pneumothorax, but without clinical appearance of respiratory distress. Since the lavaged group naturally contained the more severely distressed infants, with a high incidence of caesarean section on account of intrauterine asphyxia and lower Apgar scores at one and five minutes, the high incidence of radiologically confirmed meconium aspiration syndrome was not surprising.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Abstract Background Silent aspiration or the inhalation of foodstuffs without overt physiological signs presents a serious health issue for children with dysphagia. To date, there are no reliable means of detecting aspiration in the home or community. An assistive technology that performs in these environments could inform caregivers of adverse events and potentially reduce the morbidity and anxiety of the feeding experience for the child and caregiver, respectively. This paper proposes a classifier for automatic classification of aspiration and swallow vibration signals non-invasively recorded on the neck of children with dysphagia. Methods Vibration signals associated with safe swallows and aspirations, both identified via videofluoroscopy, were collected from over 100 children with neurologically-based dysphagia using a single-axis accelerometer. Five potentially discriminatory mathematical features were extracted from the accelerometry signals. All possible combinations of the five features were investigated in the design of radial basis function classifiers. Performance of different classifiers was compared and the best feature sets were identified. Results Optimal feature combinations for two, three and four features resulted in statistically comparable adjusted accuracies with a radial basis classifier. In particular, the feature pairing of dispersion ratio and normality achieved an adjusted accuracy of 79.8 ± 7.3%, a sensitivity of 79.4 ± 11.7% and specificity of 80.3 ± 12.8% for aspiration detection. Addition of a third feature, namely energy, increased adjusted accuracy to 81.3 ± 8.5% but the change was not statistically significant. A closer look at normality and dispersion ratio features suggest leptokurticity and the frequency and magnitude of atypical values as distinguishing characteristics between swallows and aspirations. The achieved accuracies are 30% higher than those reported for bedside cervical auscultation. Conclusion

    The aim of this study was to evaluate the oncological outcomes of hepatocellular carcinoma patients undergoing liver resection using cavitron ultrasonic surgical aspirator (CUSA) or radiofrequency (RF) based device Habib-4X.
. We prospectively analyzed the data of 280 patients who underwent liver resection for hepatocellular carcinoma at our institution from 2010-2012 with follow up till August 2016. The CUSA was used in the 163 patients whilst Habib-4X in 117 patients. The end points of analysis were oncological outcomes as disease recurrence, disease-free survival (DFS) and overall survival (OS) were estimated by the Kaplan-Meier method, which has been compared with all other existing literature on the survival study. Compared with CUSA the reported incidence of recurrence was significantly lower, in Habib-4X group; p Habib-4X group than CUSA group (50.80 vs 45.87 months, p = 0.03). The median OS was better in Habib-4X group than CUSA group (60.57 vs 57.17 months, p = 0.12) though the lesser difference in OS between the groups might be explained by the use of palliative therapies as TACE, percutaneous RFA, etc. in case of recurrence. RF based device Habib-4X, is safe and effective device for resection of hepatocellular carcinoma, in comparison to CUSA with better oncological outcomes, i.e., significantly lesser tumour recurrence and better DFS. This could be explained on the basis of systemic and local immunomodulatory effect involving induction of kupffer cells and effector CD-8 T cells that help in minimizing postoperative complications and bring more advantageous oncological outcomes.

    Abstract Rationale: In patients with oropharyngeal and nasopharyngeal bleeding, blood aspiration can make airway management difficult and lead to severe pulmonary complications. Patient concerns: A 44-year-old male patient with recurrent epistaxis underwent surgery for hemostasis. The patient aspirated blood through the endotracheal tube when he hiccupped during the surgery. Diagnosis: The patient was diagnosed with blood aspiration after intraoperative fiberoptic bronchoscopy revealed a blood clot and viscous mucus in the airways, but no sign of active bleeding. Interventions: Tracheobronchial suctioning and irrigation with normal saline was performed through the bronchoscope to remove the aspirated blood clot. Prior to emergence from anesthesia, sugammadex was administered to induce complete neuromuscular recovery and enable the patient to cough up any blood remaining in the airways. Outcomes: The patient was successfully extubated and fully recovered with no complications. Lessons: Blood aspiration due to oropharyngeal or nasopharyngeal bleeding can be diagnosed and treated by tracheobronchial suctioning via fiberoptic bronchoscopy. In addition, sugammadex can enable patients to recover spontaneous breathing, facilitate extubation, and enable patients to cough up any blood remaining in the airways. PMID:29642212

    To report a case of bladder injury with hematuria and urinary retention after transvaginal oocyte aspiration. Case report. Emergency room in a university medical center. A 28-year-old woman presented with urinary retention and suprapubic pain 8 hours after oocyte aspiration. Foley catheter, intravenous fluid bolus, bladder irrigation, and computed tomography with postvoid films that showed a blood clot in the bladder. Patient was discharged home with antibiotics and catheter in place. Clinical follow-up. Patient passed voiding trial 4 days later and was artificially inseminated. No further hematuria or voiding problems were reported, and she had a successful pregnancy. Patients who elect to undergo oocyte aspiration should be warned about the possibility of bladder injury because of the close proximity of the ovaries to the bladder, and physicians should have an appropriate treatment plan.

    A comparative study between modified conventional saline load test and the more recently introduced radioisotopic method was run in 8 normal volunteers. Each subject underwent at least three studies by each of the two methods: (1) aspiration method Goldstein and Boyle incorporating our modification, and (2) an isotopic method employing a gamma camera with a computer. A liquid metal of isotonic saline was used with or without /sup 99m/Tc-DTPA. The results indicated that the gastric emptying T 1 / 2 (8.8 +- 3.5 min) obtained by saline load test was shorter than that obtained by isotopic method (12 +- 3 min). This discrepancy was most likely due to inherent error (incomplete aspiration of the gastric fluid) in the former method giving rise to a false faster emptying time. Moreover, the variations in T 1 / 2 value in the same individual was much more in the aspiration method than it was in the isotopic method

    To describe the correlation between the functional dysphagia scale and aspiration pneumonia and which characteristics influence the occurrence of aspiration pneumonia in patients with idiopathic Parkinson disease. Fifty-three patients with idiopathic Parkinson disease were prospectively evaluated in this study. Disease severity and functional status were measured by modified Hoehn and Yahr (H&Y) staging, Schwab and England activities of daily living (S-E ADL) scale and Korean version of Mini-Mental State Examination (K-MMSE). Swallowing function was evaluated by the functional dysphagia scale (FDS) and the penetration-aspiration scale (PAS) based on a videofluoroscopic swallowing study. The patients were followed up for 3 months and divided into two groups according to the occurrence of aspiration pneumonia. The correlation between the variables and aspiration pneumonia was analyzed. Eight patients of the 53 patients were allocated to the aspiration pneumonia group and 45 patients to the non-aspiration pneumonia group. The patients in the aspiration pneumonia group had significantly higher H&Y staging, and scored lower on S-E ADL scale and K-MMSE. The patients in the aspiration pneumonia group had significantly higher scores on FDS and PAS. A multiple logistic regression analysis showed that the S-E ADL scale and the FDS were associated with the occurrence of aspiration pneumonia in the patients with Parkinson disease. Given that the FDS can quantitatively assess the functional problems associated with dysphagia, it can be clinically effective in predicting the occurrence of aspiration pneumonia, and the FDS and the S-E ADL scale could be predictive variables for aspiration pneumonia in patients with Parkinson disease.

    To analyse the cytomorphologic spectrum of Wilms tumour (WT) on aspirates, the largest series reported to date. Adequate aspirates from paediatric renal tumours over a period of 17 years were reviewed and selected if subsequent excision showed WT or aspirates were diagnostic for WT and clinical/radiological evidence consistent with that diagnosis. Smears were re-examined for the proportion of components, degree of pleomorphism and mitosis. Of 110 aspirates, smears were triphasic in 44 (40.0%), biphasic (blastema and tubules) in 36 (32.7%) and monophasic (blastema alone) in 30 (27.3%). Stromal predominance was seen in 11 aspirates (10.0%) and five showed rhabdomyoblastic differentiation; all 11 were triphasic. Mean mitotic rate was 9.3/5000 cells (range 4-39/5000). Nuclear atypia not amounting to anaplasia and without atypical mitoses was seen in 15 (13.6%); these presented diagnostic problems. Two aspirates (1.8%) were considered anaplastic (unfavourable), both having atypical mitoses. Criteria similar to histology (i.e. 3-fold or more variation in nuclear size, marked hyperchromasia with bizarre nuclei and atypical mitoses in a biphasic or triphasic aspirate) helped in distinguishing anaplastic WT. Histopathological correlation in 67 cases showed good correlation of blastemal predominance, stromal predominance and anaplastic histology with the corresponding cytology. However, 9/27 (33.3%) triphasic tumours had only blastemal cells on corresponding aspiration because of sampling error. Cytokeratin was positive in 4 of 20 aspirates with blastema alone. Aspirates from WT were triphasic or biphasic in the majority (72.7%), permitting cytological diagnosis, which was improved by cytokeratin immunocytochemistry. Blastemal and stromal predominance on histology correlated well with cytology, but many triphasic tumours showed only blastema on aspiration. Anaplastic WT can be detected on aspirates using criteria similar to histology. © 2010 Blackwell Publishing Ltd.

  16. Declotting a Thrombosed Brescia-Cimino Fistula by Manual Catheter-Directed Aspiration of the Thrombus

    Acute thrombosis of native fistulae for hemodialysis occurs more rarely than for prosthetic grafts. The vascular access should be reopened as soon as possible in order to resume regular dialysis and to avoid resorting to a temporary central line. Manual aspiration is one of the numerous methods described in this setting. Clinical examination is essential to rule out local infection, which is the only serious contraindication to percutaneous maneuvers. Two introducer-sheaths are placed in a criss-cross fashion in order to gain access to the venous outflow and to the anastomosis. Access to the venous outflow is performed first in order to check the proximal extent of the thrombosis. Heparin and antibiotics are injected systemically. A similar maneuver is then performed in the direction of the anastomosis. The aspiration phase is then initiated. A 7-9 Fr aspiration catheter is pushed through the 'venous' introducer. Manual aspiration is created through a 50 ml syringe while the catheter is progressively removed with back and forth movements. The catheter and the contents of the syringe are flushed through a gauze on the working table to evaluate the amount of thrombus which has been removed and the maneuver is repeated as often as necessary to remove all the thrombus. Once all the clots located downstream from the venous introducer have been removed, any unmasked underlying stenosis is NOT dilated at this stage since it provides protection against major embolism coming from the inflow. The aspiration catheter is then pushed through the 'arterial' introducer down to the anastomosis in order to aspirate the thrombus located between the tip of the introducer and the anastomosis. Dilatation of unmasked stenoses is finally performed using high-pressure balloons. The holes made by the two introducers are closed using a U-shaped suture with interposition of a short piece of plastic and the patient is sent back to the nephrologists for dialysis

    A 3-day-old male foal was presented with a fluctuant 25 × 15 cm mass on the thorax. The mass had increased in size since birth. The mass did not respond to conservative treatment consisting of aspiration of serohaemorrhagic contents and compression bandages, and it was therefore surgically removed...... when the foal was approximately 2½ weeks. A histopathological diagnosis of cavernous haemangioma was made. Healing progressed without complications despite a large surgical wound left to heal by second intention. Recurrence was not observed during the 1.5-year follow-up period....

    Mammography-guided interventional breast procedures, such as preoperative localization, fine-needle aspiration cytology (FNAC), and core biopsy of suspicious lesions, require accurate three-dimensional localization. The authors have evaluated a prototype stereotactic mammography device for localizing abnormalities with both phantom and clinical studies. Twenty-six localizations on a phantom were within 0.5 mm +- 0.93 (standard deviation) from the lesions; accuracy in clinical procedures was within 0.6 mm +- 0.8. Procedures are performed an average of 8 minutes faster with this device. They are prospectively evaluating mammography-guided FNAC and core biopsy of suspicious lesions in 100 patients. Results of FNAC performed without the stereotactic device agreed with results of open surgical biopsy in six of eight patients; results of core biopsy agreed in seven of eight

    Full Text Available Background: The aim of our study was to investigate if total bilirubin (T-bil, amylase (Amy, and sodium (Na in nasogastric (NG aspirates can reflect gastrointestinal motility reliably. Materials and Methods: NG aspirates from all laparotomies lasting more than 150 min in children less than 12 months old were studied for 3 months. Color of aspirates and intensity of bowel sounds were graded every 3 h by nursing staff and aspirate samples for measuring T-bil, Amy, and Na were collected independently every 12 h until an oral fluid challenge was tolerated. Results: There were 26 subjects. Mean age at surgery was 5.6 months; mean body weight at surgery was 5.8 kg. No postoperative complications occurred. While there was no reduction in average volume of NG aspirates, color change was subjective, and bowel sounds could not be standardized, T-bil decreased over time (0d: 4.4 mg/dL; 0.5d: 2.7 mg/dL; 1.0d: 1.6 mg/dL; 1.5d: 1.3 mg/dL; 2.0d: 0.4 mg/dL; 2.5d: 0.33 mg/dL; 3.0d: 0.21 mg/dL; 3.5d: 0.15 mg/dL; 4.0d: 0.06 mg/dL; 4.5d: 0.05 mg/dL; 5.0d: 0.02 mg/dL; 5.5d: 0.02 mg/dL; 6.0d: 0.01 mg/dL. Amy and Na were inconclusive. Conclusion: T-bil levels in NG aspirates may be useful as a reliable objective quantitative marker of gastrointestinal motility postoperatively.

    Full Text Available Abstract Background Although chronic aspiration has been associated with several pulmonary diseases, the inflammatory response has not been characterized. A novel rodent model of chronic aspiration was therefore developed in order to investigate the resulting innate immune response in the lung. Methods Gastric fluid or normal saline was instilled into the left lung of rats (n = 48 weekly for 4, 8, 12, or 16 weeks (n = 6 each group. Thereafter, bronchoalveolar lavage specimens were collected and cellular phenotypes and cytokine concentrations of IL-1alpha, IL-1beta, IL-2, IL-4, IL-6, IL-10, GM-CSF, IFN-gamma, TNF-alpha, and TGF-beta were determined. Results Following the administration of gastric fluid but not normal saline, histologic specimens exhibited prominent evidence of giant cells, fibrosis, lymphocytic bronchiolitis, and obliterative bronchiolitis. Bronchoalveolar lavage specimens from the left (treated lungs exhibited consistently higher macrophages and T cells with an increased CD4:CD8 T cell ratio after treatment with gastric fluid compared to normal saline. The concentrations of IL-1alpha, IL-1beta, IL-2, TNF-alpha and TGF-beta were increased in bronchoalveolar lavage specimens following gastric fluid aspiration compared to normal saline. Conclusion This represents the first description of the pulmonary inflammatory response that results from chronic aspiration. Repetitive aspiration events can initiate an inflammatory response consisting of macrophages and T cells that is associated with increased TGF-beta, TNF-alpha, IL-1alpha, IL-1beta, IL-2 and fibrosis in the lung. Combined with the observation of gastric fluid-induced lymphocyitic bronchiolitis and obliterative bronchiolitis, these findings further support an association between chronic aspiration and pulmonary diseases, such as obliterative bronchiolitis, pulmonary fibrosis, and asthma.

    Full Text Available Carcinoma ex pleomorphic adenoma (CXPA is a rare epithelial malignancy that arises from a primary or recurrent pleomorphic adenoma (PA. It may be noninvasive (NI or invasive. NI CXPA is extremely rare. Preoperative diagnosis on fine needle aspiration (FNA of CXPA may be difficult and poses a diagnostic challenge to clinicians and pathologists. Herein, we describe the FNA findings of a case of NI-CXPA. A 69-year-old woman presented with rapid enlargement of a stable parotid mass of 25 years. Cytologically, malignant cells were focally associated with metachromatic fibromyxoid matrix that was homogeneous and dense with a vague fibrillary quality. There were cell groups, papillary-like clusters and single malignant cells. The nuclei were pleomorphic with irregularly dispersed chromatin, and the cytoplasm was ill-defined and granular. Nucleoli were small to inconspicuous. Mitoses and necrosis were not seen. Cytological features were not specific for any type of salivary gland carcinoma. The FNA diagnosis was primary high-grade adenocarcinoma of the parotid gland, not otherwise specified. Facial nerve-sparing total parotidectomy was performed, which histologically showed PA interspersed with ducts and nests composed of pleomorphic atypical nuclei surrounded by extensive hyalinization. Single cells were also noted. No capsular infiltration was seen in the entirely sampled tumor. Immunohistochemistry for Ki-67 showed a higher proliferation rate in the malignant ducts and p63 positive cells focally surrounded some of the malignant ducts. Histological diagnosis was NI-CXPA. Accurate diagnosis is important for proper surgical management; however, the preoperative diagnosis of NI-CXPA is difficult to make on FNA.

    To determine whether the application of continuous aspiration of subglottic secretions (CASS) is associated with a decreased incidence of ventilator-associated pneumonia (VAP). Prospective clinical trial. Cardiothoracic ICU (CTICU) of Barnes-Jewish Hospital, St. Louis, a university-affiliated teaching hospital. Three hundred forty-three patients undergoing cardiac surgery and requiring mechanical ventilation in the CTICU. Patients were assigned to receive either CASS, using a specially designed endotracheal tube (Hi-Lo Evac; Mallinckrodt Inc; Athlone, Ireland), or routine postoperative medical care without CASS. One hundred sixty patients were assigned to receive CASS, and 183 were assigned to receive routine postoperative medical care without CASS. The two groups were similar at the time of randomization with regard to demographic characteristics, surgical procedures performed, and severity of illness. Risk factors for the development of VAP were also similar during the study period for both treatment groups. VAP was seen in 8 patients (5.0%) receiving CASS and in 15 patients (8. 2%) receiving routine postoperative medical care without CASS (relative risk, 0.61%; 95% confidence interval, 0.27 to 1.40; p = 0. 238). Episodes of VAP occurred statistically later among patients receiving CASS ([mean +/- SD] 5.6 +/- 2.3 days) than among patients who did not receive CASS (2.9 +/- 1.2 days); (p = 0.006). No statistically significant differences for hospital mortality, overall duration of mechanical ventilation, lengths of stay in the hospital or CTICU, or acquired organ system derangements were found between the two treatment groups. No complications related to CASS were observed in the intervention group. Our findings suggest that CASS can be safely administered to patients undergoing cardiac surgery. The occurrence of VAP can be significantly delayed among patients undergoing cardiac surgery using this simple-to-apply technique.

    Full Text Available Purpose: To describe the microbiological profile and clinical outcome in the eyes with culture-proven exogenous endophthalmitis. Methods: A retrospective analysis of 495 eyes diagnosed as exogenous endophthalmitis was performed over a period of 10 years. In all, aseptically collected aqueous and vitreous aspirates were cultured for bacteria and fungus using standard microbiological techniques. Gram-stain and KOH preparation of the specimens were also performed. The antibiotic susceptibility testing for bacterial isolates was performed by Kirby-Bauer disk diffusion method. The treatment was modified according to the antibiotic sensitivity profile. The final clinical ocular condition was divided into improved, stable or deteriorated. Results: Of 148 culture-proven endophthalmitis eyes, 137 (92.57% were referred from elsewhere, and 11 (7.43% belonged to our institute. Aetiologically, 76 (51.35% eyes were post-cataract surgery, 61 (41.22% were post-traumatic, 5 (3.38% eyes post-intravitreal anti-vascular endothelial growth factor injection, 5 associated with corneal diseases and 1 bleb-related endophthalmitis.

    The introduction of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) brought about significant advancement in the field of bronchoscopy. The major indications for EBUS-TBNA are lung cancer staging and diagnosis of mediastinal lymphadenopathy. This procedure is minimally invasive and cost saving, and no complications have been described in large-scale studies. In this report, we present a case of empyema, lung abscess, and mediastinal abscess that developed in a patient undergoing EBUS-TBNA; the patient subsequently recovered uneventfully after aggressive surgical debridement and antimicrobial therapy.

    Surgical simulation has benefited from a surge in interest over the last decade as a result of the increasing need for a change in the traditional apprentice model of teaching surgery. However, despite the recent interest in surgical simulation as an adjunct to surgical training, most of the literature focuses on laparoscopic, endovascular, and endoscopic surgical simulation with very few studies scrutinizing open surgical simulation and its benefit to surgical trainees. The aim of this review is to summarize the current standard of available open surgical simulators and to review the literature on the benefits of open surgical simulation. Open surgical simulators currently used include live animals, cadavers, bench models, virtual reality, and software-based computer simulators. In the current literature, there are 18 different studies (including 6 randomized controlled trials and 12 cohort studies) investigating the efficacy of open surgical simulation using live animal, bench, and cadaveric models in many surgical specialties including general, cardiac, trauma, vascular, urologic, and gynecologic surgery. The current open surgical simulation studies show, in general, a significant benefit of open surgical simulation in developing the surgical skills of surgical trainees. However, these studies have their limitations including a low number of participants, variable assessment standards, and a focus on short-term results often with no follow-up assessment. The skills needed for open surgical procedures are the essential basis that a surgical trainee needs to grasp before attempting more technical procedures such as laparoscopic procedures. In this current climate of medical practice with reduced hours of surgical exposure for trainees and where the patient's safety and outcome is key, open surgical simulation is a promising adjunct to modern surgical training, filling the void between surgeons being trained in a technique and a surgeon achieving fluency in that

    Inflammation is involved in the pathogenesis of seawater aspiration-induced acute lung injury (ALI). Although several studies have shown that Semaphorin 7A (SEMA7A) promotes inflammation, there are limited reports regarding immunological function of SEMA7A in seawater aspiration-induced ALI. Therefore, we investigated the role of SEMA7A during seawater aspiration-induced ALI. Male Sprague-Dawley rats were underwent seawater instillation. Then, lung samples were collected at an indicated time for analysis. In addition, rat pulmonary microvascular endothelial cells (RPMVECs) were cultured and then stimulated with 25% seawater for indicated time point. After these treatments, cells samples were collected for analysis. In vivo, seawater instillation induced lung histopathologic changes, pro-inflammation cytokines release and increased expression of SEMA7A. In vitro, seawater stimulation led to pro-inflammation cytokine release, cytoskeleton remodeling and increased monolayer permeability in pulmonary microvascular endothelial cells. In addition, knockdown of hypoxia-inducible factor (HIF)-1α inhibited the seawater induced increase expression of SEMA7A. Meanwhile, knockdown of SEMA7A by specific siRNA inhibited the seawater induced aberrant inflammation, endothelial cytoskeleton remodeling and endothelial permeability. These results suggest that SEMA7A is critical in the development of lung inflammation and pulmonary edema in seawater aspiration-induced ALI, and may be a therapeutic target for this disease.

    2017-09-01

    Full Text Available Background: Spontaneous pneumomediastinum (SPM and subcutaneous emphysema are rare findings in children. Various etiologies have been reported for SPM, such as foreign body aspiration in infants, especially in those aged less than three years. In addition to the complications associated with foreign body aspiration, SPM may also become a life-threatening condition if left untreated. In the present report, we discussed a case of subcutaneous emphysema, pneumothorax, and pneumomediastinum in a 13-month-old infant previously treated for pneumonia.Case report: The infant was initially presented with subcutaneous emphysema of the neck, without respiratory distress following pneumonia. In the chest radiography, mediastinal shift and possible pneumothorax were reported, and a chest tube was inserted as the respiratory condition deteriorated. Emergency bronchoscopy showed a foreign body logged in the left respiratory tract, which was removed. Three days later, the chest tube was detached, and the patient was discharged in healthy conditions within the next two days.Conclusion: Pediatricians constantly need to consider the risk of foreign body aspiration, particularly in the presence of respiratory complications, such as SPM, even in the infants with an unreliable history of foreign body aspiration

    Full Text Available Silent aspiration plays an important role in the pathogenesis of bacterial pneumonia in the elderly. Defense of the airway is impaired in the elderly by alteration in respiratory mechanics; decreased mucociliary clearance and immunosenescence. And, the number of microorganisms in the oral cavity of the elderly is usually larger than that of young adults because of gradual reduction in production of saliva. A relationship between poor oral health and respiratory disease has been suggested by a number of recent microbiologic and epidemiologic studies, especially in elder subjects; who requiring help with feeding, wearing denture/edentate, with periodontal disease, and so on. Several researchers have reported that using professional oral health care (POHC can prevent pneumonia. Oral/respiratory mucosal tissues produced cytokine that stimulated by oral microorganisms and were altered expression of various cell adhesion molecules on their surface in response to cytokine stimulation. Then, aspiration pneumonia histopathologically characterized with inflammatory response including macrophage infiltration was caused by aspiration of oral microorganisms, acid and food particle. In conclusion, silent aspiration may be a key risk factor for the pathogenesis of pneumonia in the elderly patients with poor oral hygiene.

    The objective of this systematic review was to characterize chest CT findings in patients with dysphagia and pulmonary aspiration, identifying the characteristics and the methods used. The studies were selected from among those indexed in the Brazilian Virtual Library of Health, LILACS, Indice Bibliografico Espanol de Ciencias de la Salud, Medline, Cochrane Library, SciELO, and PubMed databases. The search was carried out between June and July of 2016. Five articles were included and reviewed, all of them carried out in the last five years, published in English, and coming from different countries. The sample size in the selected studies ranged from 43 to 56 patients, with a predominance of adult and elderly subjects. The tomographic findings in patients with dysphagia-related aspiration were varied, including bronchiectasis, bronchial wall thickening, pulmonary nodules, consolidations, pleural effusion, ground-glass attenuation, atelectasis, septal thickening, fibrosis, and air trapping. Evidence suggests that chest CT findings in patients with aspiration are diverse. In this review, it was not possible to establish a consensus that could characterize a pattern of pulmonary aspiration in patients with dysphagia, further studies of the topic being needed. (author)

    Background  Intraventricular extension of a parenchymal hemorrhage is an independent predictor of poor outcome and might be complicated by delayed hydrocephalus. We describe a method for the rapid and effective removal of a lateral ventricular hematoma via catheter-based puncture and aspiration. Methods  A catheter-based aspiration of a ventricular hematoma via a frontal eminence (FE) puncture was performed in 10 patients with thalamic and ganglionic hemorrhage perforating into the lateral ventricle. Paralleling the long axis of the lateral ventricle, a flexible silicone catheter was moved anteroposteriorly and rotated simultaneously to facilitate clot aspiration and removal. Computed tomography scans before and after surgery were compared for assessment of ventricular clot volume, Graeb score, and the ventriculocranial ratio (VCR). The Glasgow Coma Scale (GCS) score and Glasgow Outcome Scale (GOS) score were assessed at 14 days and 12 months following surgery, respectively. Results  In all 10 patients, catheter-based aspiration resulted in substantial hematoma removal with a clearance rate of 64.9%, a reduced Graeb score by 61.8%, and an elevated GCS score by 52.7%. The procedure was performed safely without occurrence of another hemorrhage, infection, and catheter obstruction in any case. At 12-month follow-up, VCR was reduced by 22.5%, no delayed hydrocephalus occurred, and a favorable outcome with an average GOS of 4.6 was observed in this small cohort of patients. Conclusion  Catheter-based aspiration of a ventricular hematoma via FE puncture rapidly, efficiently, and safely reduced the clot in the ventricular system, prevented delayed hydrocephalus sufficiently, and produced a favorable outcome.

    In this study, we aimed to determine if the use of cervical auscultation (CA) as an adjunct to the clinical feeding evaluation (CFE + CA) improves the reliability of predicting oropharyngeal aspiration (abbreviated to aspiration) in children. The design of the study is based on open label, randomized controlled trial with concealed allocation. Results from children (<18 years) randomized to either CFE or CFE + CA were compared to videofluoroscopic swallow study (VFSS), the reference standard data. Aspiration was defined using the Penetration-Aspiration Scale. All assessments were undertaken at a single tertiary pediatric hospital. 155 children referred for a feeding/swallowing assessment were randomized into the CFE n = 83 [38 males; mean age = 34.9 months (SD 34.4)] or CFE + CA n = 72 [43 males; mean age = 39.6 months (SD 39.3)] group. kappa statistic, sensitivity, and specificity values, area under receiver operating curve (aROC). No significant differences between groups were found, although CFE + CA (kappa = 0.41, 95 % CI 0.2-0.62) had higher agreement for aspiration detection by VFSS, compared to the clinical feeding exam alone (kappa = 0.31, 95 % CI 0.10-0.52). Sensitivity was 85 % (95 % CI 62.1-96.8) for CFE + CA and 63.6 % (95 % CI 45.1-79.6) for CFE. aROC was not significantly greater for CFE + CA (0.75, 95 % CI 0.65-0.86) than CFE (0.66, 95 % CI 0.55-0.76) across all age groups. Although using CA as an adjunct to the clinical feeding evaluation improves the sensitivity of predicting aspiration in children, it is not sensitive enough as a diagnostic tool in isolation. Given the serious implications of missing the diagnosis of aspiration, instrumental assessments (e.g., VFSS), remain the preferred standard.

    To compare the results of percutaneous autologous bone aspiration injection and steroids injections in the treatment of unicameral bone cyst. The prospective study was conducted at Mayo Hospital, Lahore, from January 2008 to March 2014, and comprised patients diagnosed radiologically as a case of unicameral bone cyst. The patients were divided into two groups, with group 1 being treated with bone marrow aspiration injection, while group 2 was given steroids injection. Aspiration of bone marrow was done from tibial tuberosity. The 30 patients in the study were divided into two groups of 15(50%) each. In group 1, 8(53.34%) patients and in group 2, 3 (20%) patients achieved healing after the first injection (p 0.05). The mean number of procedures required in group 1 was 1.57± 0.495 (range: 01-3) and for 2.19 ± 1.076 (range: 1-5) in group 2 (p 0.05). Bone marrow aspiration injection was better than steroids in treating unicameral bone cyst.

    Airway protections is the prevention and/or removal of material by behaviors such as cough and swallow. We hypothesized these behaviors are coordinated to respond to aspiration. Anesthetized animals were challenged with simulated aspiration that induced both coughing and swallowing. Electromyograms of upper airway and respiratory muscles together with esophageal pressure were recorded to identify and evaluate cough and swallow. During simulated aspiration, both cough and swallow intensity increased and swallow duration decreased consistent with rapid pharyngeal clearance. Phase restriction between cough and swallow was observed; swallow was restricted to the E2 phase of cough. These results support three main conclusions: 1) the cough and swallow pattern generators are tightly coordinated so as to generate a protective meta-behavior; 2) the trachea provides feedback on swallow quality, informing the brainstem about aspiration incidences; and 3) the larynx and upper esophageal sphincter act as two separate valves controlling the direction of positive and negative pressures from the upper airway into the thorax.

    Purpose of the present study is to evaluate lung impairment in an acute aspiration model by using new CT method and to assess the application of the method for clinical cases. Subjects in experimental model were anesthetized and mechanically ventilated beagle dogs (n=5), and subjects in clinical cases were patients with aspiration in acute phase (n=5). For the preparation of the acute aspiration model, 2% Gastrografin (diatrizoate megulumine) aqueous solution was instilled cumulatively (0.1-3.0 ml/kg) into the right main bronchus through the endobronchial tube. Two methods of CT scan, Spirometric gating CT (SGCT) and Dynamic CT, were performed before and after instillation. SGCT can adjust the pulmonary volume at each scan by built-in spirometer. Three-dimensional reconstruction of the whole lung image was obtained with scan data by SGCT. Dynamic CT method was utilized for assessment of the ventilation dynamics. Continuous scan of the lung at the carina level was performed during ventilation and time-series image data were obtained at a rate of 5 frames/sec. The CT densitometry of the Dynamic CT images were carried out and time-attenuation curves with ventilation were analyzed. In experimental model, the whole lung images by SGCT after instillation showed invasion of Gastrografin into right lower lobe and the compensatory overinflation in the other lobes. The time-attenuation curves by Dynamic CT showed that both the mean and amplitude of the attenuation increased in the right lower lobe where the Gastrografin instilled. But the amplitude decreased when the mean value showed no apparent change at the first period of instillation. In acute phase of the aspiration, the amplitude will be the sensitive index of the ventilation impairment. In clinical case subjects were scanned during spontaneous breathing by Dynamic CT. Both the mean and amplitude of the attenuation of the time-increased when the aspiration occurred. After four days passed, the mean value increased

    Full Text Available Background: Abortion is an important social and public health issue. In Bangladesh complication from unsafe abortion is one of the leading causes of maternal mortality. It is a serious health problem. World Health Organisation estimates that 14% of maternal deaths which occur every year in the countries of South Asia including Bangladesh are due to abortion. Study shows manual vacuum aspiration procedure is safe and effective in incomplete abortion. Very few clinical trials were carried out in Bangladesh to assess the safety and effectivity of manual vacuum aspiration in managing incomplete abortion. Objective: To find out the outcome of manual vacuum aspiration in the management of patients of incomplete abortion. Materials and Methods: This observational descriptive study was conducted in the department of Obstetrics & Gynaecology, Dhaka Medical College & Hospital from June to December, 2004. One hundred cases of diagnosed incomplete abortion up to 12 weeks of gestation were managed by manual vacuum aspiration during this period. A data recording sheet was designed for this purpose. Haemodynamically stable patients with no history of induced abortion and fever were enrolled. Results: Procedure time of manual vacuum aspiration was short, average duration was 7 minutes. Bleeding was minimum (20-30 mL in 67% cases and weighted mean was 29.80 mL. Eighty three percent patients were stable during the procedure and only 3% needed blood transfusion. Nonnarcotic analgesics were used in 59% cases and 33% needed only proper counselling. Average duration of hospital stay was 2 hours. Effectiveness of the procedure was about 98% with very low post procedure complication rate (2%. Conclusion: MVA procedure is a safe and effective technique of uterine evacuation in incomplete abortion. It is quick, less expensive, effective and less painful. Hospital stay and chance of perforation of uterus is less. So this procedure should be considered by health care

    Publications and organizations ranking medical schools rely heavily on schools' research-oriented and grant-success data because those are the publicly available data. To address the vacuum of evidence for medical education quality, in 2012 the Association of Education in Europe (AMEE) introduced an initiative entitled A Schools Programme for International Recognition of Excellence in Education (ASPIRE) awards. ASPIRE panels of international experts in specific areas of medical education have developed internationally peer-based criteria to benchmark excellence in social accountability, student engagement, student assessment, faculty development, and simulation; they plan to publish criteria on curriculum design and development in 2018. Schools are encouraged to use ASPIRE criteria to challenge themselves and, for a fee, may submit evidence that they have met the criteria for excellence in one or more of the five areas. The international panels then judge the evidence submitted by the school and determine whether an award of excellence is merited.The authors share lessons learned from five years of program experience. Of the 88 schools submitting evidence, 38 have been recognized for their excellence in one of the ASPIRE topic areas. As the number of representatives from the schools that are awarded ASPIRE recognition continues to increase and those individuals find new ways to contribute, hopes are high for this program. Challenges remain in how to better define excellence in low-resources settings, what new areas to take on, and how to keep infrastructure costs down. However, as an example of continuing global interaction for quality improvement, optimism prevails.

    Accurate detection and classification of aspiration is a critical component of videofluoroscopic swallowing evaluation, the most commonly utilized instrumental method for dysphagia diagnosis and treatment. Currently published literature indicates that inter-judge reliability for the identification of aspiration ranges from poor to fairly good depending on the amount of training provided to clinicians. The majority of extant studies compared judgments among clinicians. No studies included judgments made during the use of a postural compensatory strategy. The purpose of this study was to examine the accuracy of judgments made by speech-language pathologists (SLPs) practicing in hospitals compared with unblinded expert judges when identifying aspiration and using the 8-point Penetration/Aspiration Scale. Clinicians received extensive training for the detection of aspiration and minimal training on use of the Penetration/Aspiration Scale. Videofluoroscopic data were collected from 669 patients as part of a large, randomized clinical trial and include judgments of 10,200 swallows made by 76 clinicians from 44 hospitals in 11 states. Judgments were made on swallows during use of dysphagia compensatory strategies: chin down posture with thin-liquids and thickened liquids (nectar-thick and honey-thick consistencies) in a head neutral posture. The subject population included patients with Parkinson’s disease and/or dementia. Kappa statistics indicate high accuracy for all interventions by SLPs for identification of aspiration (all К > .86) and variable accuracy (range 69%–76%) using the Penetration/Aspiration Scale when compared to expert judges. It is concluded that while the accuracy of identifying the presence of aspiration by SLPs is excellent, more extensive training and/or image enhancement is recommended for precise use of the Penetration/Aspiration Scale.

    2014-09-01

    Full Text Available Background: Breast lump is one of the most common presentations in surgical outpatient departments with anxiety regarding a possible malignancy. Hence a quick diagnosis of a lump in the breast is essential. Fine needle aspiration cytology is an ideal initial diagnostic modality in breast lumps. There is an alternative method of performing needle aspiration, known as fine needle capillary cytology where the specimen is obtained using just a needle without aspiration.Materials and Methods: This hospital-based cross sectional analytical study was carried out in Department of Pathology in National Academy of Medical Sciences, Bir Hospital for one year. The objective of this study was to compare aspiration and non-aspiration cytology of palpable breast lumps and correlation with histopathology.Results: The five criteria scored for each technique were background blood, amount of cellular material, cellular degeneration, cellular trauma and architectural preservation. Compared to fine needle aspiration cytology, fine needle capillary cytology yields less bloody smears with minimal degenerative changes and offers more diagnostically superior specimens. Fine needle aspiration cytology, on the other hand, gives a good yield of diagnostic material.Conclusion: Fine needle aspiration cytology and fine needle capillary cytology are quick, easy, safe and cost-effective techniques. . A high sensitivity and specificity of cytological diagnosis in this study proves that it is comparable to final histology report in its diagnostic efficiency. Thus, fine needle aspiration cytology is a very important preliminary diagnostic test in palpable breast lumps and the results show a high degree of correlation with the final histopathology report.DOI: http://dx.doi.org/10.3126/jpn.v4i8.11501 Journal of Pathology of Nepal; Vol.4,No. 8 (2014 639-643

    To provide optimal information to women choosing between early medical and surgical abortion, rigorous comparisons of the two methods are warranted. We compared the outcome of 1135 consecutive women with gestational age (GA) ... gemeprost) or a surgical abortion (vacuum aspiration in general anesthesia). One hundred eleven of these women were randomized for abortion method. Surgical interventions and complications leading to readmission within the following 15 weeks were identified through a computer system. Information about...... antibiotic treatment, leave of absence and number of contacts to the health care system were obtained from mailed questionnaires. The number of complications was identical after the two methods, but surgical abortion was associated with a higher success rate [97.7% (708/725) vs. 94.1% (386/410), p

    Full Text Available Solid masses of the pancreas represent a variety of benign and malignant neoplasms of the exocrine and endocrine tissues of the pancreas. A tissue diagnosis is often required to direct therapy in the face of uncertain diagnosis or if the patient is not a surgical candidate either due to advanced disease or comorbidities. Endoscopic ultrasound (EUS is a relatively new technology that employs endoscopy and high-frequency ultrasound (US. EUS involves imaging of the pancreatic head and the uncinate from the duodenum and imaging of the body and tail from the stomach. It has been shown to be a highly sensitive method for the detection of pancreatic masses. It is superior to extracorporeal US and computed tomographic (CT scans, especially when the pancreatic tumor is smaller than 2-3 cm. Although EUS is highly sensitive in detecting pancreatic solid masses, its ability to differentiate between inflammatory masses and malignant disease is limited. Endoscopic retrograde cholangiopancreatography (ERCP brushing, CT-guided biopsies, and transabdominal ultrasound (US have been the standard nonsurgical methods for obtaining a tissue diagnosis of pancreatic lesions, but a substantial false-negative rate has been reported. Transabdominal US-guided fine-needle aspiration biopsy (US-FNAB has been used for tissue diagnosis in patients with suspected pancreatic carcinoma. It has been shown to be highly specific, with no false-positive diagnoses. With the advent of curvilinear echoendoscopes, transgastric and transduodenal EUS-FNAB of the pancreas have become a reality EUS with FNAB has revolutionized the ability to diagnose and stage cancers of the gastrointestinal tract and assess the pancreas. Gastrointestinal cancers can be looked at with EUS and their depth of penetration into the intestinal wall can be determined. Any suspicious appearing lymph nodes can be biopsied using EUS/FNAB. The pancreas is another organ that is well visualized with EUS. Abnormalities

    Full Text Available AIM:To compare surgical peeling and aspiration and neodymium yttrium garnet laser capsulotomy for pearl form of posterior capsule opacification (PCO.METHODS:A prospective, randomized, double blind, study was done at Rotary Eye Hospital, Maranda, Palampur, India, Santosh Medical College Hospital, Ghaziabad, India and Laser Eye Clinic, Noida India. Consecutive patients with pearl form of PCO following surgery, phacoemulsification, manual small incision cataract surgery and conventional extracapsular cataract extraction (ECCE for age related cataract, were randomized to have peeling and aspiration or neodymium yttrium garnet laser capsulotomy. Corrected distance visual acuity (CDVA, intra-operative and post-operative complications were compared.RESULTS:A total of 634 patients participated in the study, and 314 (49.5% patients were randomized to surgical peeling and aspiration group and 320 (50.5% to the Nd:YAG laser group. The mean pre-procedural logMAR CDVA in peeling and neodymium:yttrium-aluminium-garnet (Nd:YAG laser group was 0.80±0.25 and 0.86±0.22, respectively. The mean final CDVA in peeling group (0.22±0.23 was comparable to Nd:YAG group (0.24±0.28; t test, P=0.240. There was a significant improvement in vision after both the procedures (P<0.001. A slightly higher percentage of patients in Nd:YAG laser group (283/88.3% than in peeling group (262/83.4% had a CDVA of 0.5 (20/63 or better at 9mo (P<0.001. On the contrary, patients having CDVA worse than 1.00 (20/200 was also significantly higher in Nd:YAG laser group as compared to peeling group (25/7.7% vs 15/4.7%, respectively. On application of ANCOVA, there was less than 0.001% risk that PCO thickness and total laser energy had no effect on rate of complications in Nd:YAG laser group and less than 0.001 % risk that PCO thickness had no effect on complications in peeling group respectively. Sum of square analysis suggests that in the Nd:YAG laser group, thick PCO had a stronger impact

    A preterm neonate, with a gestational age of 30 1/7 weeks, was born after a period of prolonged rupture of the membranes and a retroplacental haematoma causing vaginal bleeding. During admission to the neonatal intensive-care unit, mechanical ventilation was indicated because of acute respiratory failure following blood aspiration, which was causing oxygenation and ventilation problems. Endotracheal surfactant was administered and, because of persistent pulmonary hypertension of the newborn (PPHN), NO-inhalation therapy was started. A quick recovery was seen and two days post partum the patient could be extubated. Blood aspiration may cause acute respiratory problems and PPHN, with quick recovery after effective mechanical ventilation, surfactant and NO-inhalation therapy.

    2012-01-01

    Exploiting a randomized natural experiment in India, we show that female leadership influences adolescent girls’ career aspirations and educational attainment. A 1993 law reserved leadership positions for women in randomly selected village councils. Using 8,453 surveys of adolescents aged 11–15 and their parents in 495 villages, we find that, compared to villages that were never reserved, the gender gap in aspirations closed by 25% in parents and 32% in adolescents in villages assigned to a female leader for two election cycles. The gender gap in adolescent educational attainment is erased and girls spent less time on household chores. We find no evidence of changes in young women’s labor market opportunities, suggesting that the impact of women leaders primarily reflects a role model effect. PMID:22245740

    The techniques and applications of amniocentesis performed with a new high-frequency aspiration-biopsy transducer are described in detail. The advantages of this technique are greatest in third-trimester patients where active fetal motion and diminished amniotic fluid volumes make unguided punctures difficult or impossible. The ability to visualize small-caliber needles within the fluid space further enhances the effectiveness of this technique.

    Diffraction-enhanced imaging (DEI) is a type of phase contrast x-ray imaging that has improved image contrast at a lower dose than conventional radiography for many imaging applications, but no studies have been done to determine if DEI might be useful for diagnosing lung injury. The goals of this study were to determine if DEI could differentiate between healthy and injured lungs for a rat model of gastric aspiration and to compare diffraction-enhanced images with chest radiographs. Radiographs and diffraction-enhanced chest images of adult Sprague Dawley rats were obtained before and 4 hours after the aspiration of 0.4 mL/kg of 0.1 mol/L hydrochloric acid. Lung damage was confirmed with histopathology. The radiographs and diffraction-enhanced peak images revealed regions of atelectasis in the injured rat lung. The diffraction-enhanced peak images revealed the full extent of the lung with improved clarity relative to the chest radiographs, especially in the portion of the lower lobe that extended behind the diaphragm on the anteroposterior projection. For a rat model of gastric acid aspiration, DEI is capable of distinguishing between a healthy and an injured lung and more clearly than radiography reveals the full extent of the lung and the lung damage.

    Full Text Available Oral care is a crucial routine for patients with dysphagia that, when completed routinely, can prevent the development of aspiration pneumonia. There is no standardised protocol for oral care within government hospitals in South Africa. This study aimed to investigate the outcome of an oral care protocol. Participants were patients with oropharyngeal dysphagia, with either stroke or traumatic brain injury as the underlying medical pathology, and nurses. All participants were recruited from one tertiary level government hospital in Gauteng, South Africa. 139 nurses participated in the study and received training on the oral care protocol. There were two groups of participants with oropharyngeal dysphagia. Group one (study group, n = 23 was recruited by consecutive sampling, received regular oral care and were not restricted from drinking water; however, all other liquids were restricted. Group two (comparison group, n = 23 was recruited via a retrospective record review, received inconsistent oral care and were placed on thickened liquids or liquid restricted diets. Results showed that a regimen of regular oral care and free water provision when combined with dysphagia intervention did prevent aspiration pneumonia in patients with oropharyngeal dysphagia. The article highlights two key findings: that regular and routine oral care is manageable within an acute government hospital context and a strict routine of oral care can reduce aspiration pneumonia in patients with oropharyngeal dysphagia. An implication from these findings is confirmation that teamwork in acute care settings in developing contexts must be prioritised to improve dysphagia management and patient prognosis.

    The potential of foreign body aspiration or ingestion is a worldwide health problem in dentistry. The general dental practitioners should be extremely attentive in handling of minor instruments during any intervention related to the oral cavity, especially in the supine or semi-recumbent position of the patient. Aspiration cases are usually more critical and less common than ingestion. We report a case of iatrogenic aspiration of an endodontic broach, which gets disclosed during the recording of past dental history of the patient. The patient was asymptomatic during that time. A quick posterior-anterior chest radiograph was taken which revealed the presence of broach in the lower lobe of the left lung. The patient was immediately referred to the pulmonary medicine department where the fiberoptic bronchoscope retrieval was planned, and the same was carried out successfully under local anesthesia. Although such accidents have rare occurrence, the associated risks and morbidity are too high to be overlooked, especially from the viewpoint of special care, resources, and the associated financial cost required for their management. Moreover, practitioners are also liable for malpractice litigation given the fact that such cases are avoidable. This article also discusses relevant review literature, risk factors, symptoms, and management of such iatrogenic accidents along with drawing attention to the significance of preventive measures and their role in avoiding meritorious legal and ethical issues.

    2007-01-01

    Full Text Available Abstract Background Fine needle aspiration biopsy (FNAB is gaining increasing popularity in the diagnosis of musculoskeletal lesions; and in many patients, a definitive diagnosis can be rendered from aspiration smears alone. Its applicability in bone pathology, however, has been controversial due to a high percentage of inadequate smears, difficulty in evaluation of tissue architecture and nonspecific results in the diagnosis of primary bone lesions. In this study, the value of aspiration as the first pathological investigation in the diagnosis of a bone lesion was evaluated. Methods 91 cases of clinically suspected cases of bone lesions were aspirated over a period of two years. Direct or cytospin smears were fixed in 95% alcohol and stained by Hematoxylin and Eosin or air-dried and later fixed in methanol for May Grŭnwald Giemsa staining. Results Of the 91 patients who were subjected to FNAB, 81 were considered satisfactory and 10.9 % (10 were inadequateinconclusive for diagnosis. Cyto-histological concordance was obtained in 78.5 % (51/65 patients. Positive and negative predictive values were 87.5% and 97.2 % respectively. Sensitivity as a preliminary diagnostic technique was 93.3%, whereas specificity was 94.5 %. Overall, diagnostic accuracy was 94.2 %. Metastatic lesions were detected with 100% accuracy. Two cases were reported as false positive and one case as false negative. Conclusion Cytology provides valuable information to the clinician to make an informed decision regarding appropriate therapy. We conclude that time-consuming and costly investigations may be reduced by choosing FNAB as the initial pathological diagnostic method for skeletal lesions of unknown origin. The choice of radiological examinations, laboratory tests and surgical biopsies can be determined after the FNAB diagnosis.

    Intractable aspiration is a serious, often life-threatening condition due to its potential impact on pulmonary function. Aspiration requires therapeutic measures, starting with conservative management but often necessitating surgical treatment. The basic surgical principle is to separate the alimentary and respiratory tracts through a variety of procedures which, unfortunately, nearly all result in the loss of phonation, with the exception of total laryngectomy (TL) which includes the placement of an indwelling voice prosthesis. In this study, we present a modified laryngotracheal separation (LTS) technique that, we believe, offers multiple advantages compared to standard TL. After reviewing the medical records of 35 patients with intractable aspiration who have undergone LTS, we describe the surgical technique and present the postoperative result. In a second surgical procedure about two months following LTS, we aimed to achieve voice restoration by placement of an indwelling voice prosthesis. Intractable aspiration was successfully treated in all patients. Placement of an indwelling voice prosthesis during a second operation was successful in 15 patients, representing the largest reported cohort thus far. LTS is a reliable surgical technique to treat intractable aspiration, with restoration of oral intake, thereby improving the general condition and quality of life of these unfortunate patients. Furthermore, voice restoration can be achieved in selected patients, by placement of a voice prosthesis.

    Social media is an influential tool that has the power to transform cytopathology. Twitter is being used more and more to share cutting-edge updates from pathology meetings ("live-tweeting"). Modern smartphones can now take high resolution microscopic photographs and easily transmit them worldwide via Twitter, Facebook, and other social media, allowing cytopathologists to share educational pearls and discuss difficult cases on a global scale like never before. Social media also allows cytopathologists to share a behind-the-scenes look at their subspecialty with other physicians and even the non-medical public, helping them to better understand the crucial importance of cytopathology in modern medicine. This could positively impact rapport with other specialties, influence policy making, and possibly even improve delivery of patient care. Rare disease patient communities are being formed by patients on Facebook. By joining and volunteering with these patient groups, cytopathologists would have further opportunity to interact directly with patients and their family members, explaining the role of cytopathology in patient care and helping patients to better understand their own diseases. Social media enables cytopathologists and their colleagues in other pathology subspecialties to easily and rapidly form a broad and diverse worldwide network with one another. The authors believe that this is the key to a bright future for our specialty, a strong unified global community of pathologists all working together for education, patient advocacy, and outstanding patient care. Social media can allow us to build that community, strengthen its bonds, and harness its power like never before in history. Diagn.

    Facial defects with loss of hair-bearing regions can be caused by trauma, infection, tumor excision, or burn injury. The presented analysis evaluates a series of different surgical approaches with a focus on male beard reconstruction, emphasizing the role of tissue expansion of regional and free flaps. Locoregional and free flap reconstructions were performed in 11 male patients with 14 facial defects affecting the hair-bearing bucco-mandibular or perioral region. In order to minimize donor-site morbidity and obtain large amounts of thin, pliable, hair-bearing tissue, pre-expansion was performed in five of 14 patients. Eight of 14 patients were treated with locoregional flap reconstructions and six with free flap reconstructions. Algorithms regarding pre- and intraoperative decision making are discussed and long-term (mean follow-up 1.5 years) results analyzed. Major complications, including tissue expander infection with the need for removal or exchange, partial or full flap loss, occurred in 0% (0/8) of patients with locoregional flaps and in 17% (1/6) of patients undergoing free flap reconstructions. Secondary refinement surgery was performed in 25% (2/8) of locoregional flaps and in 67% (4/6) of free flaps. Both locoregional and distant tissue transfers play a role in beard reconstruction, while pre-expansion remains an invaluable tool. Paying attention to the presented principles and considering the significance of aesthetic facial subunits, range of motion, aesthetics, and patient satisfaction were improved long term in all our patients while minimizing donor-site morbidity.

    Fetal magnetic resonance imaging (MRI) examinations have become well-established procedures at many institutions and can serve as useful adjuncts to ultrasound (US) exams when diagnostic doubts remain after US. Due to fetal motion, however, fetal MRI exams are challenging and require the MR scanner to be used in a somewhat different mode than that employed for more routine clinical studies. Herein we review the techniques most commonly used, and those that are available, for fetal MRI with an emphasis on the physics of the techniques and how to deploy them to improve success rates for fetal MRI exams. By far the most common technique employed is single-shot T2-weighted imaging due to its excellent tissue contrast and relative immunity to fetal motion. Despite the significant challenges involved, however, many of the other techniques commonly employed in conventional neuro- and body MRI such as T1 and T2*-weighted imaging, diffusion and perfusion weighted imaging, as well as spectroscopic methods remain of interest for fetal MR applications. An effort to understand the strengths and limitations of these basic methods within the context of fetal MRI is made in order to optimize their use and facilitate implementation of technical improvements for the further development of fetal MR imaging, both in acquisition and post-processing strategies.

    Respiratory foreign body aspiration (FBA) is a common global health problem requiring prompt recognition and early treatment to prevent potentially fatal complications. The majority of FBAs are due to organic objects and treatment is usually via either endoscopic or surgical extraction. FBA of a straight hairpin has been described as a unique entity in the literature, occurring most commonly in females, particularly during adolescence. In the process of inserting hairpins, the pins will typically be between the teeth with the head tilted backwards, while tying their hair with both hands. This position increases the risk of aspiration, particularly if there is any sudden coughing or laughing. To our knowledge, this is the first case report of a 35-mm straight metallic hairpin foreign body that has been successfully retrieved by a radiological snare system under fluoroscopic guidance. This was achieved with the use of a split endotracheal tube, and therefore avoided the need for a thoracotomy in an adolescent female patient.

    We report a case of old gravel aspiration in a 57-year-old man who had been accidentally buried in a field of construction for ten hours, three years prior. A chest radiograph showed peribronchial pneumonic infiltrates in the right lower lobe, with a proximal ovoid radiopaque endobronchial density at the trunchus basalis. These findings were more clearly visualized on the 64-channel multidetector CT (MDCT). Moreover, the patient recovered from his condition, following a bronchoscopic retrieval. However, the patient had persistent bronchiectasis of the right lower lobe on a subsequent follow-up chest radiograph, one month later.

Of the 835 aspirates, 174 were reported as positive, 549 as negative and 66 as suspicious or atypical but not diagnostic of malignancy. Forty-six cases were considered unsatisfactory. Tissue was available for comparison in 286 cases. The cytologic diagnoses in these cases were reported as follows: positive, 125 (43.7%); suspicious, 33 (11.5%); atypical, 18 (6.2%); negative, 92 (32%); and unsatisfactory, 18 (6.2%). There was one false positive diagnosis, yielding a false positive rate of 0.8%. This lesion was a case of fibrocystic change with hyperplasia, focal fat necrosis and reparative atypia. There were 14 false negative cases, resulting in a false negative rate of 13.2%. Nearly all these cases were sampling errors and included infiltrating ductal carcinomas (9), ductal carcinomas in situ (2), infiltrating lobular carcinomas (2) and tubular carcinoma (1). Most of the suspicious and atypical lesions proved to be carcinomas (35/50). The remainder were fibroadenomas (6), fibrocystic change (4), gynecomastia (2), adenosis (2) and granulomatous mastitis (1). A positive diagnosis of malignancy by FNA is reliable in establishing the diagnosis and planning the treatment of breast cancer. The false-positive rate is very low, with only a single case reported in 835 aspirates. Most false negatives are due to sampling and not to interpretive difficulties. The category "suspicious but not diagnostic of malignancy" serves a useful purpose in management of patients with breast lumps.

    Ardies, Jan; De Maeyer, Sven; Gijbels, David

    2015-09-01

    Background: More young people, boys and girls, are needed in technical studies and professions, as the relative number of students in technology-related studies has been decreasing in most industrialised countries. To overcome this decrease several countries implemented mandatory technology classes in the curriculum of secondary education. Purpose: This study has two goals: exploring the evolution of pupils' interest during the year(s) they attend the mandatory technology classes and exploring determining characteristics for differences in boys' and girls' attitude change over time. Sample: This study focuses on data gathered in the first and second grade of the first cycle in general secondary education in the North region of Belgium, Flanders. In a first stage we selected a good representation of geographically spread schools (n = 20), from which over 1300 students participated. Design and methods: A longitudinal study with eight measurement occasions spread over the course of two years is presented in order to capture the evolution of students' attitudes, making use of a multilevel growth model analysis. Results: The results show that students' interest in technology decreases over time, although at the end of each grade interest is increasing again. Boys' and girls' interest in technology also evolves a little different in the first cycle of secondary education. For career aspirations we didn't see any significant difference between boys and girls. Boys' and girls' aspirations decrease over time with a little increase by the end of the second grade. Students with a more technological curriculum also have more career aspirations in the field of technology than their peers with other curricula. Although students' perceptions about technology as a subject for boys and girls are largely stable. Conclusions: The evolution of students' attitude is far from linear, this strengthens us in the choice for a more complex analysis model and the choice for more measuring

    Objective: To compare ultrasound guided fine-needle aspiration cytology (FNAC) and core needle biopsy (CNB) in patients presenting with palpable breast lumps (PBLs), in terms of sensitivity and specificity, taking final histopathology as gold standard. Methodology: This cross-sectional study was conducted at Holy Family Hospital, Rawalpindi, Pakistan. Ultrasound guided FNAC and CNB were taken of all female patients with PBLs. The results were compared with final histopathology as gold standard. Data analysis was performed using SPSS software and chi-square test. Results: A total of 60 patients were included in the study. The mean age was 33.8 yrs. The sensitivity and specificity of ultrasound guided FNAC were 68.7% and 93.1%, respectively. The sensitivity and specificity of ultrasound guided CNB was 93.7% and 100%. The accuracy of FNAC was 86.2% and that of core needle biopsy was 98.3%. Conclusion: The ultrasound guided core needle biopsy can be used as an initial diagnostic test for the evaluation of all PBLs. Because of high negative predictive value core needle biopsy can replace surgical excision biopsy for benign lesions. (author)

  1. Surgical infections: a microbiological study

    Full Text Available Surgical infections are mostly polymicrobial, involving both aerobes and anaerobes. One hundred seventeen cases comprised of abscesses (n=51, secondary peritonitis (n=25, necrotizing fascitis (n=22 and wounds with devitalized tissues (n=19 were studied. The number of microorganisms isolated per lesion was highest in secondary peritonitis (2.32. The aerobe/ anaerobe ratio was 0.81 in secondary peritonitis and 1.8 in necrotizing fascitis. Most secondary peritonitis (80%, necrotizing fascitis (75% and wounds with devitalized tissues (66.7% were polymicrobial. Common microorganisms isolated in our study were E. coli, Staphylococcus aureus, Klebsiella spp., Pseudomonas aeruginosa, Bacteroides fragilis and Peptostreptococcus spp. The most effective antibiotics for S. aureus were clindamycin (79.1% and cefuroxime (70.8%. For Gram-negatives (Klebsiella spp., E. coli and Proteus spp., the most effective antibiotics were cefotaxime, ceftizoxime, amikacin and ciprofloxacin. Pseudomonas aeruginosa was maximally sensitive to amikacin (35.2% and ciprofloxacin (35.2%. The greatest degree of multidrug resistance to all the drugs was found in P. aeruginosa (52.9%, followed by Klebsiella spp. (33.3%, Proteus spp. (33.3%, E. coli (22.2%, and S. aureus (12.5%. All the anaerobes that we isolated were 100% sensitive to metronidazole and chloramphenicol, followed by clindamycin (95% to 100%. Apart from antibiotic therapy, non-antimicrobial methods, such as hyperbaric oxygen therapy and debridement also play an important role in the treatment of surgical infections.

    Full Text Available Paragangliomas (PGLs are uncommon tumors. Although PGLs are known to occur in the head and neck region, especially the carotid body, middle ear, and larynx, involvement of the parotid glands has not been reported. In this article, we report the fine needle aspiration features of tumor in an unusual location, presenting as a parotid gland mass, submitted to pathology for initial diagnosis. The clinical presentation, cytomorphology, and the immunohistochemical features for the diagnosis are described. To our knowledge, this is the first case of paraganglioma of the parotid gland reported in the literature.

  4. Fine needle aspiration cytology of pseudosarcomatous reactive lesions of soft tissues: A report of two cases

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Pseudosarcomatous lesions are reactive proliferative lesions of the soft tissue, that are likely to be misdiagnosed as malignant, based on clinical and histological features. The most common lesions are nodular fasciitis, proliferative fasciitis, proliferative myositis and myositis ossificans. These rapidly growing soft-tissue lesions can represent a variety of diagnoses involving radically different treatment modalities. Accurate diagnosis is important to avoid unnecessary and often mutilating surgery. We report two cases to illustrate the importance of correct identification of these lesions by fine needle aspiration cytology.

    Recurrent aspiration of milk into the respiratory tract has been implicated in the pathogenesis of a variety of inflammatory lung disorders including asthma. However, the lack of animal models of aspiration-induced lung injury has limited our knowledge of the pathophysiological characteristics of this disorder. This study was designed to evaluate the effects of recurrent milk aspiration on airway mechanics and lung cells in a murine model. Under light anesthesia, BALB/c mice received daily intranasal instillations of whole cow's milk (n = 7) or sterile physiologic saline (n = 9) for 10 d. Respiratory system resistance (Rrs) and dynamic elastance (Edyn,rs) were measured in anesthetized, tracheotomized, paralyzed and mechanically ventilated mice 24 h after the last aspiration of milk. Rrs and Edyn,rs were derived from transrespiratory and plethysmographic pressure signals. In addition, airway responses to increasing concentrations of i.v. methacholine (Mch) were determined. Airway responses were measured in terms of PD(100) (dose of Mch causing 100% increase from baseline Rrs) and Rrs,max (% increase from baseline at the maximal plateau response) and expressed as % control (mean +/- SE). We found recurrent milk aspiration did not affect Edyn and baseline Rrs values. However, airway responses to Mch were increased after milk aspiration when compared with control mice. These changes in airway mechanics were associated with an increased percentage of lymphocytes and eosinophils in the bronchoalveolar lavage, mucus production, and lung inflammation. Our findings suggest that recurrent milk aspiration leads to alterations in airway function, lung eosinophilia, and goblet cell hyperplasia in a murine model.

    Background/Aims We attempted to examine the relationship between abnormal findings on high-resolution manometry (HRM) and videofluoroscopic swallowing study (VFSS) of the pharynx and upper esophageal sphincter (UES), and to identify the risk factors for aspiration. Methods We performed VFSS and HRM on the same day in 36 ischemic stroke patients (mean age, 67.5 years) with dysphagia. Pressure (basal, median intra bolus, and nadir), relaxation time interval of the UES, and mesopharyngeal and hypopharyngeal contractility (as a contractile integral) were examined using HRM. The parameters of VFSS were vallecular residue, pyriform sinus residue, vallecular overflow, penetration, and aspiration. The association between the parameters of VFSS and HRM was analyzed by the Student’s t test. Results Three (8.3%) and 4 (11.1%) stroke patients with dysphagia had pyriform sinus residue and vallecular sinus residue, respectively, and 5 (13.8%) patients showed aspiration. Mesopharyngeal and hypopharyngeal contractile integrals in patients with residue in the pyriform sinus were significantly lower than those in patients without residue in the pyriform sinus (P < 0.05). Relaxation time intervals in patients with aspiration were significantly shorter than those in patients without aspiration (P < 0.05), and multivariate regression analysis revealed a shorter relaxation time interval as the main risk factor for aspiration (OR, 0.03; 95% CI, 0.01–0.65; P < 0.05). Conclusions Manometric measurements of the pharynx and UES were well correlated with abnormal findings in the VFSS, and a shorter relaxation time interval of the UES during deglutition is an important parameter for the development of aspiration.

    Full Text Available Introduction. This paper compares different approaches to recanalization in a model of the middle cerebral artery (MCA. Methods. An occlusive thrombus (lamb's blood was introduced into the MCA of a model of the cerebral circulation perfused with Hartmann's solution (80 pulsations/min, mean pressure 90 mm Hg. Three methods of clot retrieval were tested: thrombus aspiration via a 4F catheter (n=26, thrombus aspiration via the GP thrombus aspiration device (GPTAD (n=30, and mechanical thrombectomy via the Solitaire Device (n=30. Results. Recanalization rate was similar for all 3 approaches (62%, 77%, and 85%. Time to recanalization was faster with aspiration devices (41 SD 42 s for 4F and 61 SD 21 s for GPTAD than with the Solitaire (197 SD 64 s P<.05 Kruksal-Wallis. Clot fragmentation was the same in the Solitaire (23% and the GPTAD (23%, but higher with the 4F (53%, P<.05. Conclusion. In this model, thrombus aspiration was faster than mechanical thrombectomy, and similarly effective at recanalization. These results should be confirmed in vivo.

    Our purpose was to review needle aspiration of breast abscesses and identify factors associated with treatment by aspiration alone versus aspiration with surgical incision and drainage (I/D). This Institutional Review Board-approved, retrospective review of the breast ultrasound database from 2008 to 2010 identified 40 patients (41 abscesses) who underwent aspiration, with or without I/D. Demographics, imaging, number of aspirations, and microbiology were reviewed. Twenty-two abscesses underwent aspiration only, 16 > 3 cm, 6 ≤ 3 cm (mean 4.3 cm, range 0.9-10 cm). Known risk factors included lactational (11), 3 weeks post partum (1), pregnancy (1), recent biopsy/lumpectomy (5). Nineteen abscesses underwent aspiration and I/D, 15 > 3 cm, 4 ≤ 3 cm (mean 4.1 cm, range 2.2-7.5 cm). Known risk factors included lactational (4), recurrent subareolar abscess (4), diabetes (3), hydradenitis suppuritiva (1), nipple piercing (2), smoking (1), pregnancy (1), HIV (1), and lumpectomy (1). Identified reasons for I/D included lack of improvement/recurrence (12), fistula (3), and one electively after clinical improvement of a recurrent subareolar abscess. Abscesses associated with pregnancy and lactation or breast biopsy are effectively managed with aspiration, even when large. Recurrence, chronicity, or fistula may require surgical intervention. © 2014 Wiley Periodicals, Inc.

    Full Text Available Background: Fine needle aspiration cytology (FNAC is effective in the diagnosis of bone tumors when combined with careful radiologic and clinical evaluation. Chondrosarcomas often arise in the pelvis or bones of the trunk, but primary chest wall (rib chondrosarcomas are relatively rare. Case Reports: This is a case of a patient with a chondrosarcoma arising in the left lower rib who underwent resection. The patient was a 30-year-old man with a 10x8x6cm tumor in the anterior chest wall of the left side lower rib. On Fine Needle Aspiration Cytology (FNAC of the mass on the anterior chest wall, a diagnosis of a low grade chondrosarcoma was made. This was confirmed histopathologically as a dedifferentiated chondrosarcoma. Macroscopically on excision of gray to pink lobulated mass with adjacent soft tissue and bone with foci of hemorrhage and necrosis the mass measured (M 10x 8x 6 cm. Incidence of chondrosarcoma peaks in the 5th to 6th decade and most commonly involves the femur, humerus, pelvis, and scapula. It rarely involves rib.

    Dysphagia is the main cause of aspiration pneumonia and death in Parkinson disease (PD) with no established restorative behavioral treatment to date. Reduced swallow safety may be related to decreased elevation and excursion of the hyolaryngeal complex. Increased submental muscle force generation has been associated with expiratory muscle strength training (EMST) and subsequent increases in hyolaryngeal complex movement provide a strong rationale for its use as a dysphagia treatment. The current study's objective was to test the treatment outcome of a 4-week device-driven EMST program on swallow safety and define the physiologic mechanisms through measures of swallow timing and hyoid displacement. This was a randomized, blinded, sham-controlled EMST trial performed at an academic center. Sixty participants with PD completed EMST, 4 weeks, 5 days per week, for 20 minutes per day, using a calibrated or sham, handheld device. Measures of swallow function including judgments of swallow safety (penetration-aspiration [PA] scale scores), swallow timing, and hyoid movement were made from videofluoroscopic images. No pretreatment group differences existed. The active treatment (EMST) group demonstrated improved swallow safety compared to the sham group as evidenced by improved PA scores. The EMST group demonstrated improvement of hyolaryngeal function during swallowing, findings not evident for the sham group. EMST may be a restorative treatment for dysphagia in those with PD. The mechanism may be explained by improved hyolaryngeal complex movement. This intervention study provides Class I evidence that swallow safety as defined by PA score improved post EMST.

    2017-01-01

    Full Text Available Background: Thrombocytopenia may be encountered in various hematological and nonhematological conditions and may be associated with dysplastic megakaryocytes which is a feature of myelodysplastic syndrome (MDS, even though they can be observed in non-MDS hematological conditions. Objective: To study the morphological variations of megakaryocytes on bone marrow aspiration smears in non-MDS-related thrombocytopenia in a Medical College in Bengaluru, Karnataka. Materials and Methods: It was a prospective study of 86 cases of non-MDS thrombocytopenia whose bone marrow aspirates were studied morphologically. Results: The most common cause of thrombocytopenia was acute leukemia followed by other systemic malignancies, megaloblastic anemia, and idiopathic thrombocytopenic purpura. Both dysplastic and nondysplastic features were observed in the above-mentioned conditions. The most common dysplastic feature was nuclear segmentation followed by micromegakaryocytes and hypogranular forms. Among nondysplastic features, the most common were immature forms, bare nuclei, and hypolobation. Emperipolesis and cytoplasmic vacuoles were noted in a case of pyrexia of unknown origin. Conclusion: Dysplastic megakaryocytes are common in non-MDS-related thrombocytopenia and their mere presence should not lead to the diagnosis of MDS. Hence, proper diagnosis should be made on megakaryocyte morphology, patient's clinical findings, and other hematological parameters. This understanding can improve the diagnostic accuracy for wide range of hematological disorders.

    2013-01-01

    Full Text Available Bone-marrow aspirate material is commonly considered as one of the most sensitive tissues for a reliable diagnosis of leishmaniasis. The procedure herein described may permit less experienced veterinarians to be familiar with a quick and safe assessment method for leishmaniasis diagnosis in their patients. Animals are positioned in right lateral recumbency, and the area corresponding to the second, third, or fourth sternebra is identified and aseptically prepared. A 18-gauge needle connected to a 10 mL syringe is driven through the skin, up to the bone wall, and firmly pushed forward while rotating. Entry into the sternebra’s cavity is clearly perceived by the fall of resistance offered by the cortex. Some 2,500 sternal bone-marrow samplings were safely and efficiently performed on 887 dogs of different breeds and aging from 6 months to 14 years, during eight years of clinical activity for routine diagnosis of canine leishmaniasis in pets or for the efficacy evaluation of anti-Leishmania immunobiologicals in dogs naturally exposed to parasite transmission. Most of the samples (1716 were from 387 dogs enrolled for anti-Leishmania vaccine studies. The safety of the method was particularly assessed on these dogs that as per study protocol were submitted to repeated bone-marrow aspirations (2–4 per year in follow-up examinations.

    The clinical diagnosis of a mass in the neck region encompasses a wide spectrum of differential diagnosis. Fine-needle aspiration is a quick and safe technique, which can provide useful information for initial assessment and further therapeutic measures. The aim of this retrospective study was to evaluate the performance characteristics of the fine-needle aspiration (FNA) in cystic neck lesions. Of 142 patients with FNA for cystic neck masses during 2002-2007, 92 cases were selected with a follow-up histologic diagnosis, excluding the cystic colloid nodule of the thyroid. The cases were divided into salivary gland cystic neck (37 patients) and non-salivary cystic neck (55 patients) mass groups. False-positive and false-negative diagnoses were applied only to the malignant lesions after confirmation by histopathology. In the first group, nine malignant and 28 benign diagnoses were made by FNA; of which three were false-negative. In the second group, there were nine malignant and 46 benign diagnoses with three false negatives. The overall performance of the FNA showed 76% sensitivity and 100% specificity. In conclusion, FNA of the cystic neck lesions offers an invaluable and highly specific initial diagnostic approach for the management of the patients. (c) 2009 Wiley-Liss, Inc.

    'une plaque plane avec aspiration. La paroi poreuse s'etend sur 1 m de longueur, a partir d'une distance de 1 m en aval du bord d'attaque. Le nombre de Reynolds d'epaisseur de la couche limite en l'absence d'aspiration est de l'ordre de 16,300. Le taux d'aspiration, defini comme le rapport a la vitesse generale de la vitesse normale a la paroi, est reglable de 0 a 2 pour cent. Le gradient de pression est controlable. On a determine en diverses positions et pour divers taux d'aspiration: avec des sondes de prise de pression totale, les profils de vitesse moyenne, avec des anemometres a fils chauds, analyseur spectral et correlateur, les intensites des differentes composantes des fluctuations turbulentes de vitesse, les spectres d'energie, les correlations. On deduit de ces mesures: le trace des lignes de courant, les valeurs des tensions de frottement visqueux et turbulent, du frottement local a la paroi, et du terme de production de l'energie turbulente, ainsi que des indications sur la dissipation de cette energie. Pour ces calculs, l'equation integree de conservations de la masse dans la couche limite a ete etablie. L'influence de l'aspiration sur la couche limite est importante: elle modifie profondement la forme des profils de vitesse moyenne, augmentant les tensions de frottement visqueux a la paroi, les diminuant ailleurs; elle diminue les intensites de turbulence longitudinale et transversale ainsi que les tensions de frottement turbulent et la production d'energie turbulente. Ces effets sont tres marques dans la zone interne de la couche limite. Par contre, l'etude des spectres d'energie indique que l'echelle de la turbulence, est peu modifiee, l'epaisseur de la couche limite ne diminuant que faiblement sous l'influence de l'aspiration. Les effets de l'aspiration peuvent etre apprecies en comparant le double du taux d'aspiration au coefficient de frottement a la paroi (supposee etanche); notables des que ce rapport depasse l'unite, ils deviennent tres importants

    Full Text Available Endometriosis is often associated with sterility. In 20–50 % of women with endometriosis the ovaries are affected. Ovarian endometrioma often present with inhomogeneous ultrasound patterns. The differentiation to other ovarian tumors could be difficult. In case of primary diagnosis, histological findings are indicated, all the more as ovarian endometriosis has an increased risk for malignant transformation. Therapeutic surgical intervention should be done in sano.brNevertheless, to affect a compromise in case of infertility, especially in patients with reduced ovarian reserve, laparoscopic aspiration or laser coagulation after fenestration could be a second option with the occurrence of small recurrent endometriomas. A histological diagnosis should be done, too. The surgical procedure should be discussed with the department of reproductive medicine.brThe effect of endometriomas on the reproductive outcome is not clear. Systematic reviews have shown that regarding pregnancy rates, endometriomas do not have to be necessarily removed. Primary ultrasound-guided transvaginal aspiration of endometriomas should be avoided to decrease the risk of infection. If the same is the truth in case of accidental aspiration during the oocyte retrieval, remains unproven. Contaminated follicular fluid by endometrioma content may have an influence on clinical pregnancy and live birth rate. p bKurzfassung: /bEndometriose und Sterilität sind häufig assoziiert.

  1. The Role of School Performance in Narrowing Gender Gaps in the Formation of STEM Aspirations: A Cross-National Study

    2015-02-01

    Full Text Available Abstract This study uses cross-national evidence to estimate the effect of school peer performance on the size of the gender gap in the formation of STEM career aspirations. We argue that STEM aspirations are influenced not only by gender stereotyping in the national culture but also by the performance of peers in the local school environment. Our analyses are based on the Program for International Student Assessment (PISA. They investigate whether 15-year-old students from 55 different countries expect to have STEM jobs at the age of 30. We find considerable gender differences in the plans to pursue careers in STEM occupations in all countries. Using PISA test scores in math and science aggregated at the school level as a measure of school performance, we find that stronger performance environments have a negative impact on student career aspirations in STEM. Although girls are less likely than boys to aspire to STEM occupations, even when they have comparable abilities, boys respond more than girls to competitive school performance environments. As a consequence, the aspirations gender gap narrows for high-performing students in stronger performance environments. We show that those effects are larger in countries that do not sort students into different educational tracks.

    This study uses cross-national evidence to estimate the effect of school peer performance on the size of the gender gap in the formation of STEM career aspirations. We argue that STEM aspirations are influenced not only by gender stereotyping in the national culture but also by the performance of peers in the local school environment. Our analyses are based on the Program for International Student Assessment (PISA). They investigate whether 15-year-old students from 55 different countries expect to have STEM jobs at the age of 30. We find considerable gender differences in the plans to pursue careers in STEM occupations in all countries. Using PISA test scores in math and science aggregated at the school level as a measure of school performance, we find that stronger performance environments have a negative impact on student career aspirations in STEM. Although girls are less likely than boys to aspire to STEM occupations, even when they have comparable abilities, boys respond more than girls to competitive school performance environments. As a consequence, the aspirations gender gap narrows for high-performing students in stronger performance environments. We show that those effects are larger in countries that do not sort students into different educational tracks.

    Full Text Available We report the case of a patient with a pseudoaneurysm of the ascending aortic clinically diagnosed 5 months after surgical replacement of the aortic valve. Diagnosis was confirmed with the aid of two-dimensional echocardiography and helicoidal angiotomography. The corrective surgery, which consisted of a reinforced suture of the communication with the ascending aorta after opening and aspiration of the cavity of the pseudoaneurysm, was successfully performed through a complete sternotomy using extracorporeal circulation, femorofemoral cannulation, and moderate hypothermia, with no aortic clamping.

    Foreign matter aspiration occurs relatively commonly in drowning and near-drowning events. In most cases, stomach contents are aspirated. Sand aspiration rarely occurs and there are no reported cases in children with near drowning. Limited data are available on clinical presentation and management of sand aspiration with accidental burial. We report a 3-year-old boy who nearly drowned while swimming in brackish waters and was found face down in sand. Sand aspiration was suspected when the child continued to have persistent wheezing and high ventilatory requirement despite intensive bronchodilator and corticosteroids therapy with an inability to wean after 4 days post-near-drowning event. Radiology was non-specific in the absence of sand bronchogram. Presence of sand in the airways was confirmed when a bronchoscopy was undertaken and sand seen in the bronchoalveolar lavage fluid. Sequential lung washing followed by exogenous surfactant administration (3 ml/kg) was undertaken and lead to significant improvement such that within 12 hr post-therapeutic lavage, his ventilatory requirements reduced substantially. The child was extubated 4 days post-lavage and on review 2 months post-event, was clinically well with airway resistance within normal predicted values measured on forced oscillatory spirometry (IOS).

    Conclusion: Fine-needle aspiration cytology in cysticercosis is a low-cost outpatient procedure. The cytological diagnosis is quite straightforward in cases where the actual parasite structures are identified in the smears. In other cases, a cytological diagnosis of suspicious of cysticercosis can be given if the cytological findings suggest the same.

    Full Text Available Background. Fine needle aspiration (FNA remains the first-line diagnostic in management of thyroid nodules and reduces unnecessary surgeries. However, it is still challenging since cytological results are not always straightforward. This study aimed to examine the results of thyroid FNA using the Bethesda system for reporting thyroid cytopathology (TBSRTC to establish the level of accuracy of FNA procedures in a rural practice setting. Method. A retrospective chart review was conducted on existing thyroid FNA performed in a referral endocrine center between December 2011 and November 2015. Results. A total of 159 patients (18–88 years old and 236 nodule aspirations were performed and submitted for evaluation. 79% were benign, 3% atypia/follicular lesion of unknown significance (AUS/FLUS, 5% follicular neoplasm/suspicious for follicular neoplasm (FN/SFN, 4% suspicious for malignancy (one case was indeed an atypical parathyroid neoplasm by surgical pathology, 2% malignant, and 7% nondiagnostic. Two cases also had advanced molecular analysis on FNA specimens before thyroidectomy. Conclusion. The diagnostic yield of FNA cytology from our practice in a rural setting suggests that accuracy and specificity are comparable to results from larger centers.

    Syringe aspiration for manual aspiration thrombectomy (MAT) is a cost- and time-efficient alternative to an aspiration pump with likely similar efficacy. It is counterintuitive to expect the pump to perform better than direct vacuum with a syringe, as the pump must deliver vacuum additionally through a canister and meters of tubing. To present in vitro and clinical results of MAT with a syringe. An in vitro analysis was performed comparing vacuum pressures generated by syringe aspiration and with pump aspiration. This was then complemented with prospective clinical data providing details of angiographic and clinical outcomes for syringe MAT. The in vitro analysis demonstrated that equal to slightly greater vacuum pressures were generated by a 60 cc syringe as compared with the pump in both static and partial flow conditions. In our clinical series, 106/113 acute stroke thrombectomies over a 6-month period were performed with syringe MAT on the first pass. Syringe usage instead of pump tubing and a canister led to a total savings of $58 300. The rate of Thrombolysis in Cerebral Infarction 2b/3 recanalization was 93%. Adjunctive stentriever usage was performed in 23% of cases. Median puncture to reperfusion time was 25 min; mean change in National Institute of Health Stroke Scale score at 24 hours was an improvement of 5.1 (median 6). The in-hospital mortality rate was 10%. Seventy percent of patients were discharged to home (modified Rankin Scale (mRS) score 0-2) or a rehabilitation facility (mRS score 2-4). MAT using a syringe is a safe, fast, and more cost-effective approach than using an aspiration pump. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available We present a social work study on relationship between parenting styles and career aspirations as well as psychological well-being among third year high school female students in city of Khomeinishahr, Iran during the year of 2012. The study selects a sample of 300 students from 1260 female students who were enrolled in third year high school education, randomly. The study uses the Baumrind’s questionnaire on parenting style, which consists of 30 questions which equally measure three parenting styles including authoritarian, indulgent and authoritative in Likert scale. The survey also uses Gottfredson’s questionnaire to examine occupational aspirations. The study examines whether there is any relationship between parenting style from one side and three personal characteristics including gender, career aspiration and wishes type on the other side. Using Chi-Square technique, the survey examines three hypotheses and the results confirm all three hypotheses of the survey.

    Basic surgical skills are an integral part of surgical training. Simulation-based surgical training offers an opportunity both to trainees and trainers to learn and teach surgical skills outside the operating room in a nonpatient, nonstressed environment. However, widespread adoption of simulation technology especially in medical education is prohibited by its inherent higher cost, limited space, and interruptions to clinical duties. Mobile skills laboratory has been proposed as a means to address some of these limitations. A new program is designed by the Royal College of Surgeons in Ireland (RCSI), in an approach to teach its postgraduate basic surgical trainees the necessary surgical skills, by making the use of mobile innovative simulation technology in their own hospital settings. In this article, authors describe the program and students response to the mobile surgical skills being delivered in the region of their training hospitals and by their own regional consultant trainers.

    2011-08-01

    Truancy and alcohol use are quality indicators of academic achievement and success. However, there remains a paucity of substantive research articulating the impact these deviant behaviors have on an adolescent's educational aspirations. The purpose of this study is to assess whether recent alcohol use and truancy impact students' educational aspirations among a nationally representative sample of US high school seniors. This study conducted a secondary data analysis of the Monitoring the Future project data, 2006. Logistic regression was conducted to assess how alcohol use and truancy affected educational aspirations. Subsequent interaction effects were assessed in the final multivariable model. Demographic variables such as age, sex, race, and father and mother's educational level were included as covariates in the regression model. Results indicate that as students engage in increased alcohol use and/or truancy, educational aspirations decrease. Thus, students who indicated a desire to attend a 4-year college/university were less likely to engage in high-risk drinking behavior and/or truancy. Moreover, in testing the interaction between truancy and alcohol use, as it relates to educational aspirations, the logistic regression model found both of these independent variables to be statistically significant predictors of the likelihood students would attend a 4-year college/university. To ensure that adolescents further their education and maximize their potential life opportunities, school and public health officials should initiate efforts to reduce alcohol consumption and truancy among students. Furthermore, future research should examine the risk and protective factors that may influence one's educational aspirations. © 2011, American School Health Association.

    Objective The aim of our study is to determine if a fresh cadaver model (FCM) for the instruction of ultrasound (US)-guided fine-needle aspiration (FNA) of thyroid nodules is a practical method for instruction. Study Design Pre- and postinstruction assessment of medical students' ability to perform US-guided FNA of artificially created thyroid nodules placed adjacent to the thyroid gland of a fresh cadaver. Setting University-based fresh cadaver laboratory. Subjects and Methods Study participants included a total of 17 first- and second-year medical students with minimal US training. Technical skills were assessed using a 10-item checklist. In addition, a cognitive assessment regarding the indications, contraindications, and complications of the procedure was completed. A postinstruction assessment was provided for participants 5 weeks after their initial assessment. Differences between pre- and postinstruction assessment scores of technical skills were analyzed using McNemar's test. The mean cognitive knowledge gain was analyzed using a paired 2-sample t test. Results Eight of 10 items on the skills checklist were statistically significant between pre- and postinstruction skills assessment ( P < .05). There was a statistically significant change in cognitive knowledge gain regarding the contraindications of the procedure ( P = .001), but not for indications or complications ( P = .104 and P = .111, respectively). Conclusion US-guided FNA continues to be an important diagnostic procedure in the workup of thyroid nodules, making it an essential skill to integrate into surgical skills lab. Our FCM for the instruction of US-guided FNA is the first of its kind, and this pilot study shows this is a viable method for instruction.

    We sought to define an accurate measure of thoracic surgical education costs. Program directors from six distinct and differently sized and geographically located thoracic surgical training programs used a common template to provide estimates of resident educational costs. These data were reviewed, clarifying questions or discrepancies when noted and using best estimates when exact data were unavailable. Subsequently, a composite of previously published cost-estimation products was used to capture accurate cost data. Data were then compiled and averaged to provide an accurate picture of all costs associated with thoracic surgical education. Before formal accounting was performed, the estimated average for all programs was approximately $250,000 per year per resident. However, when formal evaluations by the six programs were performed, the annual cost of resident education ranged from $330,000 to $667,000 per year per resident. The average cost of $483,000 per year was almost double the initial estimates. Variability was noted by region and size of program. Faculty teaching costs varied from $208,000 to $346,000 per year. Simulation costs ranged from $0 to $80,000 per year. Resident savings to program ranged from $0 to $135,000 per year and averaged $37,000 per year per resident. Thoracic surgical education costs are considerably higher than initial estimates from program directors and probably represent an unappreciated source of financial burden for cardiothoracic surgical educational programs.

    The nursing shortage of registered nurses in Canada is expected to worsen, making recruitment a concern for nursing organizations. Also, many reports have outlined the need for improved leadership in nursing. Therefore, the study purpose was to describe the findings of a systematic review of studies examining the career influences and aspirations of gifted high school students and to make recommendations for further research. Results indicate gifted students choose careers that fit their personal self-concept and their perceptions of traits needed to succeed in a profession. Family members, particularly mothers, had the greatest influence on career decision making and these students were more likely to indicate a desire for a profession with high prestige, high levels of education and higher pay. These students were not likely to indicate nursing as a career choice. Efforts to improve the image of nursing with this group of students are needed.

    Full Text Available The aspiration of barium contrast is a rare complication that may occur during studies of the digestive tract. Barium is an inert material that can cause anywhere from an asymptomatic mechanical obstruction to serious symptoms of respiratory distress that can result in patient death. We present the case of a 79-year-old male patient in whom we observed the presence of contrast medium residue in the lung parenchyma as an incidental finding during hospitalization. When the patient’s medical file was reviewed, images were found of a barium swallow study that the patient had undergone months earlier, and we were able to observe the exact moment of the aspiration of the contrast material. The patient had been asymptomatic since the test.

    Full Text Available Pituitary carcinoma (PC is a very rare entity (0.2% of all pituitary tumors, with only about 140 cases reported in English literature. There are no reliable histological, immunohistochemical or ultrastructural features distinguishing pituitary adenoma (PA from PC. By definition, a diagnosis of PC is made after a patient with PA develops non-contiguous central nervous system (CNS or systemic metastases. To date, only three cases of PC have been reportedly diagnosed on fine needle aspiration (FNA. Two of the reported cases were diagnosed on FNA of the cervical lymph nodes and one on FNA of the vertebral bone lesion. Herein, we present a case of PC, diagnosed on FNA of the liver lesion. In this case, we describe cytologic features of PC and compare them to histologic features of the tumor in the pituitary. Clinical behavior of tumor, pathogenesis of metastasis and immunochemical and prognostic markers will also be described.

    Between 1979 and 2004, 167 patients younger than 20 years were treated surgically for humeral or femoral unicameral bone cysts with either injection of corticosteroids (steroids), curettage plus bone grafting (curettage), or a combination injection of steroids, demineralized bone matrix, and bone marrow aspirate (SDB) at Children's Hospital of Boston and Massachusetts General Hospital (mean followup, 7.3 years; range, 1 month-27 years). Outcomes included treatment failure (defined clinically as subsequent pathologic fracture or need for retreatment to prevent pathologic fracture) and complications. Information was obtained from medical records and by telephone questionnaire. After one treatment, 84% of cysts treated with steroids experienced failed treatment versus 64% with curettage and 50% with SDB. For unicameral bone cysts requiring retreatment (regardless of first treatment), 76% retreated with steroids had failed treatment versus 63% with curettage and 71% with SDB. Curettage was associated with the lowest rate of posttreatment pathologic fractures and highest rate of pain and other complications. Multivariate logistic regression indicated treatment with steroids alone and younger age were independent predictors of failure. We believe SDB is a reasonable first treatment for unicameral bone cysts in the humerus and femur in patients younger than 20 years, being less invasive yet comparable to curettage in preventing recurrence.

    Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive technique that allows lung cancer nodal staging and biopsy of parabronchial and paratracheal tissue. Its simplicity, high diagnostic yield, ability to diagnose both benign and malignant conditions, and exceedingly low complication rate has resulted in rapid widespread adoption by surgeons and physicians. EBUS-TBNA-related complications, however, do occur and need to be considered when assessing the risk-benefit profile of performing the procedure, and if the patient represents with unexpected symptoms after the procedure. We describe a 64-year-old woman who presented with a mediastinal abscess 5 days after EBUS-TBNA. This case demonstrates the importance of considering EBUS-TBNA-related complications to guide relevant imaging decisions and antibiotic choices. We review the published literature regarding infective complications of EBUS-TBNA and propose possible pathophysiologies. These complications are likely to increase in frequency as the technique is more widely adopted.

  3. Fine needle aspiration cytology in feline skeletal muscle as a diagnostic tool for extramedullary plasmacytoma

    Directory of Open Access Journals (Sweden)

    D.B. Martins

    Full Text Available ABSTRACT Extramedullary noncutaneous plasmacytoma (ENP is a myeloproliferative disorder of plasma cells that rarely affects cats. This paper describes an ENP case revealed by fine needle aspiration cytology (FNAC of the mass in the skeletal muscle of an 8-month-old, male, mixed breed cat, which had a nodule in the left hind limb. The rapid immunoassay test confirmed the presence of feline leukemia virus (FeLV. The animal necropsy macroscopically showed the nodule came from the semimembranosus muscle. Histopathological examination ratified the cytological findings. Thus, this paper alerts to the existence of plasmacytoma located in the skeletal muscle of feline species. FNAC is a quick and efficient method for diagnosis of ENP.

  4. "Everybody Gotta Have a Dream": Rap-centered Aspirations among Young Black Males Involved in Rap Music Production - A Qualitative Study.

    Science.gov (United States)

    Foster, B Brian

    Youth express diverse desires for their educational and occupational futures. Sometimes these aspirations are directed towards somewhat unconventional careers such as rapping and other types of involvement in rap music production. Although many studies have examined traditional educational and occupational aspirations, less is known about the factors that give rise to rap-centered aspirations and how individuals pursue them, particularly as they transition to early adulthood. Drawing on 54 semi- and unstructured interviews with 29 black young men involved in rap music production, I find that rap-centered aspirations are shaped by a range of factors, most notably feedback regarding one's rap skills, access to recording and production equipment, and the financial means to maintain involvement in rap music production while also ensuring personal and family economic stability. The young men in the study attached different meanings to their aspirations and sometimes recast their motivations for participating in rap music production in response to various social and economic factors.

    2016-01-01

    Full Text Available Chondroblastoma is a rare, giant cell-rich, benign neoplasm of bone. Since the past few decades fine needle aspiration cytology (FNAC has gained momentum in preoperative diagnosis of bone lesions. At cytology, other giant cell-rich tumors and tumorlike lesions such as aneurysmal bone cyst (ABC, giant cell tumor, and chondromyxoid fibroma fall under the differential diagnosis of chondroblastoma. Due to the difference in the treatment protocol and prognosis, preoperative diagnosis is mandatory. We describe the cytomorphology in two cases of chondroblastoma diagnosed at FNAC and confirmed by histopathology. At cytology, the presence of giant cells, chondroid matrix, mononuclear cells with nuclear indentation, and grooving along with glassy, vacuolated cytoplasm are characteristic of chondroblastoma. In addition to this, the presence of chicken wire calcification is a useful clue to the accurate diagnosis of chondroblastoma at FNAC.

    2014-01-01

    Objective: To compare the efficacy and safety of Manual Vacuum Aspiration (MVA) performed as outpatient versus inpatient procedure in terms of success rate, blood loss, hospital stay and procedure related complications. Study Design: A quasi-experimental study. Place and Duration of Study: Maternal and Child Health Centre (MCHC), Unit-I, Pakistan Institute of Medical Sciences (PIMS), Islamabad, from December 2009 to December 2010. Methodology: Cases with early pregnancy failure (incomplete, missed and an embryonic) at gestational age less than 12 weeks were allocated to MVA as outpatient or elective procedure performed in the operation theatre. Studied variables were noted as above. Results: A total of 177 women were eligible for study, out of whom 78 underwent MVA as outpatient procedure and 99 as indoor procedure. The baseline characteristics were comparable in both groups except significantly high multipara in the indoor group. Complete evacuation was achieved in 96.1% in outpatient vs. 79.7% in indoor cases (p=0.001). Outpatient group had a shorter hospital stay (median 3 hours, IQR-1 vs. 10 hours, IQR-4; p = 0.001), though the median hospital cost was less but statistically insignificant (Rs. 800, IQR-25 vs. 735, IQR-1265; p=0.728). Blood loss was comparable in both groups (median 60 ml, IQR-20 vs. 60 ml-IQR-30; p=0.350). There were two uterine perforations noted in the inpatient group (2.02%) vs. none in outpatient setting. Conclusion: Outpatient based manual vacuum aspiration is a safe and effective tool for management of early pregnancy loss. A decentralized approach proved useful in reducing hospital stay. (author)

    Serious, preventable surgical events, termed never events, continue to occur despite considerable patient safety efforts. To examine the incidence and root causes of and interventions to prevent wrong-site surgery, retained surgical items, and surgical fires in the era after the implementation of the Universal Protocol in 2004. We searched 9 electronic databases for entries from 2004 through June 30, 2014, screened references, and consulted experts. Two independent reviewers identified relevant publications in June 2014. One reviewer used a standardized form to extract data and a second reviewer checked the data. Strength of evidence was established by the review team. Data extraction was completed in January 2015. Incidence of wrong-site surgery, retained surgical items, and surgical fires. We found 138 empirical studies that met our inclusion criteria. Incidence estimates for wrong-site surgery in US settings varied by data source and procedure (median estimate, 0.09 events per 10,000 surgical procedures). The median estimate for retained surgical items was 1.32 events per 10,000 procedures, but estimates varied by item and procedure. The per-procedure surgical fire incidence is unknown. A frequently reported root cause was inadequate communication. Methodologic challenges associated with investigating changes in rare events limit the conclusions of 78 intervention evaluations. Limited evidence supported the Universal Protocol (5 studies), education (4 studies), and team training (4 studies) interventions to prevent wrong-site surgery. Limited evidence exists to prevent retained surgical items by using data-matrix-coded sponge-counting systems (5 pertinent studies). Evidence for preventing surgical fires was insufficient, and intervention effects were not estimable. Current estimates for wrong-site surgery and retained surgical items are 1 event per 100,000 and 1 event per 10,000 procedures, respectively, but the precision is uncertain, and the per

    Glottal closure is an important part of the mechanism that protects the airway during the normal swallow. Glottal insufficiency disrupts glottal closure and therefore puts patients at risk of aspiration. Treatment of glottal insufficiency can be classified as surgical or nonsurgical. The objective of treating glottal insufficiency is to avoid aspiration or penetration of secretions or food into the airway. Nonsurgical treatment consists of swallowing maneuvers and other measures. Surgical treatment of glottal insufficiency includes injection laryngoplasty, medialization thyroplasty with or without arytenoid adduction or with arytenopexy and cricothyroid subluxation, hypopharyngoplasty, cricopharynx muscle dilation, and cricopharynx myotomy.

    A non-lipophilic coryneform bacterium isolated from an anaerobic Bactec bottle inoculated with an ankle aspirate from a male patient was characterized by phenotypic and molecular taxonomic methods. Chemotaxonomic investigations revealed the presence of short-chain mycolic acids in the cell wall of the bacterium, a feature consistent with members of the genus Corynebacterium. Comparative 16S rRNA gene sequence analysis demonstrated that the isolate displayed 92.0-99.0 % gene sequence similarity with members of the genus Corynebacterium, with Corynebacterium ureicelerivorans as the most closely related phylogenetic species (99.0 % gene sequence similarity). However, the isolate could be genomically separated from C. ureicelerivorans on the basis of DNA-DNA hybridization studies (39.5 % relatedness). Furthermore, the isolate could also be differentiated from C. ureicelerivorans and other species of the genus Corynebacterium on the basis of biochemical properties. Based on both phenotypic and phylogenetic evidence, it is proposed that this isolate be classified as representing a novel species, Corynebacterium pilbarense sp. nov. (type strain IMMIB WACC 658(T)=DSM 45350(T)=CCUG 57942(T)).

    Full Text Available Needle biopsy is a medical intervention method for taking a lung tissue sample that suspected as a cancer. The disadvantage is the physicians directly visualize the anatomical structures in an open surgery for lung cancer biopsy procedure. There is a need to develop an instrument that may help the physician to guarantee the accuracy and efficiency while performing needle aspiration biopsy. Therefore, a needle aspiration biopsy monitoring instrument or named as NAOMI is proposed. It consists of a microcontroller system, an IMU sensor, an ultrasonic ranging module, a bluetooth module, and a 9V lithium battery. The experimental testing consist of performance testing, functional testing using chest phantom, and user acceptances. The results showed that the NAOMI improve the accuracy and efficiency while performing the needle biopsy operation.

  15. Investing in a Surgical Outcomes Auditing System

    Bermudez, Luis; Trost, Kristen; Ayala, Ruben

    2013-01-01

    Background. Humanitarian surgical organizations consider both quantity of patients receiving care and quality of the care provided as a measure of success. However, organizational efficacy is often judged by the percent of resources spent towards direct intervention/surgery, which may discourage investment in an outcomes monitoring system. Operation Smile's established Global Standards of Care mandate minimum patient followup and quality of care. Purpose. To determine whether investment of resources in an outcomes monitoring system is necessary and effectively measures success. Methods. This paper analyzes the quantity and completeness of data collected over the past four years and compares it against changes in personnel and resources assigned to the program. Operation Smile began investing in multiple resources to obtain the missing data necessary to potentially implement a global Surgical Outcomes Auditing System. Existing personnel resources were restructured to focus on postoperative program implementation, data acquisition and compilation, and training materials used to educate local foundation and international employees. Results. An increase in the number of postoperative forms and amount of data being submitted to headquarters occurred. Conclusions. Humanitarian surgical organizations would benefit from investment in a surgical outcomes monitoring system in order to demonstrate success and to ameliorate quality of care. PMID:23401763

    To describe the prevalence, management, and career outcomes of ophthalmology residents who struggle with surgical competency and to explore related educational issues. Fourteen-question written survey. Fifty-eight program directors at Accreditation Council on Graduate Medical Education-accredited, United States ophthalmology residency programs, representing a total of 2179 resident graduates, between 1991 and 2000. Study participants completed a mailed, anonymous survey whose format combined multiple choice and free comment questions. Number of surgically challenged residents, types of problems identified, types of remediation, final departmental decision at the end of residency, known career outcomes, and residency program use of microsurgical skills laboratories and applicant screening tests. One hundred ninety-nine residents (9% overall; 10% mean per program) were labeled as having trouble mastering surgical skills. All of the programs except 2 had encountered such residents. The most frequently cited problems were poor hand-eye coordination (24%) and poor intraoperative judgment (22%). Most programs were supportive and used educational rather than punitive measures, the most common being extra practice-laboratory time (32%), scheduling cases with the best teaching surgeon (23%), and counseling (21%). Nearly one third (31%) of residents were believed to have overcome their difficulties before graduation. Other residents were encouraged to pursue medical ophthalmology (22%) or to obtain further surgical training through a fellowship (21%) or a supervised practice setting (12%); these residents were granted a departmental statement of satisfactory completion of residency for Board eligibility. Twelve percent were asked to leave residency. Of reported career outcomes, 92% of residents were practicing ophthalmology, 65% as surgical and 27% as medical ophthalmologists. Ninety-eight percent of residency programs had microsurgical practice facilities, 64% had a formal

    The purpose of the work was to assess the contribution to diagnosis and/or treatment (CDT) of bone marrow aspiration (BMA) in the critically ill patient. The retrospective study included 193 patients. On the basis of BMA findings, contribution to diagnosis was defined by one of four previously unestablished diagnoses (maturation arrest of granulocyte precursors, hemophagocytic lymphohistiocytosis, hematological malignancy, marrow infiltration with cancer cells) and to treatment as the initiation or withdrawal of a specific treatment including the decision to forgo life-sustaining treatment (DFLST). A CDT of BMA was observed in 40/193 patients (20.7%). BMA contributed to diagnosis in 37 cases (granulocyte precursor maturation arrest, N  = 10; hemophagocytic lymphohistiocytosis, N  = 12; hematological malignancy, N  = 15) and to treatment in 14, including three DFLSTs. In multivariate analysis, the factors associated with a CDT were hematological malignancy, cancer or non-malignant hematological abnormality known on admission, indication for BMA excluding isolated thrombocytopenia, higher pre-BMA HScore (calculated prior to BMA), and higher SOFA score with or without platelet-count SOFA subscore. In the 160 patients without hematological malignancy or cancer known on admission, non-malignant hematological abnormality known on admission, indication for BMA excluding isolated thrombocytopenia, higher pre-BMA HScore, and higher SOFA score calculated with or without platelet-count SOFA subscore were independently associated with a CDT of BMA. BMA can have a significant CDT in ICU patients with or without a known hematological malignancy or cancer on admission. An HScore calculated before BMA can be a valuable tool for predicting a CDT of BMA.

    The effectiveness of the calf-squeeze technique during aspiration thrombectomy using guiding catheter in the treatment of an acute lower extremity deep vein thrombosis (DVT) was evaluated by the use of imaging and the clinical follow-up of patients. A prospective analysis of ten patients (seven women, three men; median age, 56.9 years) with common iliac vein (CIV) obstruction and ipsilateral DVT was performed for this study. All patients presented with leg edema or pain and were treated with catheter-directed thrombolysis via an ipsilateral popliteal vein approach after insertion of a temporary inferior vena cava (IVC) filter. Subsequently, the patients were treated with by aspiration thrombectomy using a guiding catheter to remove the residual thrombus. The calf-squeeze technique during aspiration thrombectomy can be used to induce the proximal migration of thrombi in the popliteal, tibial, and muscular veins were used to increase venous flow. The calf-squeeze technique was employed at mean of 1.3 times (range, 1-3 times). All patients showed proximal migration of a popliteal and muscular vein thrombus during the execution of the calf-squeeze technique. Successful recanalization was achieved in all patients (100%) without any complications. On duplex ultrasonography, which was performed immediately after the aspiration thrombectomy, four patients had a residual thrombus in the soleal muscular veins. However, none of the patients had a thrombus in the popliteal and tibial veins; and, during follow-up, no DVT recurred in any patient. The use of the calf-squeeze technique during aspiration thrombectomy after catheter-directed thrombolysis can induce the proximal migration of thrombi in the popliotibial and muscular veins and is an effective method that can remove a thrombus in calf veins.

    The best technique for the first attempt at mechanical thrombectomy for acute ischemic stroke is a still matter of debate. In this study, we evaluate the efficacy of a stent-retrieving into an aspiration catheter with proximal balloon (ASAP) technique that uses a series of thrombus extraction by withdrawing the stent retriever into the aspiration catheter and continuous aspiration from the aspiration catheter at the first attempt. We performed a retrospective analysis of 42 consecutive patients with acute ischemic stroke caused by occlusions in the anterior circulation who were treated with the ASAP technique at our institution. Preoperative patient characteristic, including age, thrombus location, Alberta Stroke Program Early CT Score, National Institutions of Health Stroke Scale, and time from onset to puncture; postoperative Thrombolysis in Cerebral Infarction score; modified Rankin Scale score after 3 months; time from puncture to recanalization; the number of passes to achieve recanalization; and procedural complications, including intracranial hemorrhage, embolization to new territory, and distal embolization, were assessed. A Thrombolysis in Cerebral Infarction score of 2B or 3 was achieved in 40/42 patients (95.2%). Average time from puncture to the final recanalization was 21.5 minutes. Recanalization was achieved in a single attempt in 31 patients (77.5%). Embolization to new territory was observed in only 2 patients (4.8%); no patient developed distal embolization or intracranial hemorrhage including asymptomatic subarachnoid hemorrhage. Thirty-two patients (76.2%) achieved modified Rankin Scale scores of 0-2 at 3 months postoperatively. Our ASAP technique showed fast recanalization, minimal complications, and good clinical outcomes in this case series. Copyright © 2017 Elsevier Inc. All rights reserved.

    Acute ischemic stroke is a potentially devastating condition and leading cause of morbidity and mortality, affecting an estimated 800 000 people per year in the USA. The natural history of untreated or unrevascularized large vessel occlusions in acute stroke patients results in mortality rates approaching 30%, with only 25% achieving good neurologic outcomes at 90 days. Recently, data have demonstrated that early endovascular recanalization of large vessel occlusions results in better outcomes than medical therapy alone. However, the majority of patients in these studies were treated with a stent retriever based approach. The purpose of COMPASS is to evaluate whether patients treated with a direct aspiration first pass (ADAPT) approach have non-inferior functional outcomes to those treated with a stent retriever as the firstline (SRFL) approach. All patients who meet the inclusion and exclusion criteria and consent to participate will be enrolled at participating centers. Treatment will be randomly assigned by a central web based system in a 1:1 manner to treatment with either ADAPT or SRFL thrombectomy. Statistical methodology is prespecified with details available in the statistical analysis plan. The trial recently completed enrollment, and data collection/verification is ongoing. The final results will be made available on completion of enrollment and follow-up. This paper details the design of the COMPASS trial, a randomized, blinded adjudicator, concurrent, controlled trial of patients treated with either ADAPT or SRFL approaches in order to evaluate whether ADAPT results in non-inferior functional outcome.

    To elucidate factors, other than those clinical, precipitating the risk of aspiration in hospitalized patients. The Critical Incident Technique was adopted for this study in 2015. Three departments located in two academic hospitals in the northeast of Italy, equipped with 800 and 1500 beds, respectively. A purposeful sample of 12 registered nurses (RN), all of whom (i) had reported one or more episodes of aspiration during the longitudinal survey, (ii) had worked ≥3 years in the department, and (iii) were willing to participate, were included. Antecedent factors involved in episodes of aspiration as experienced by RNs were collected through an open-ended interview, and qualitatively analysed. In addition to clinical factors, other factors interacting with each other may precipitate the risk of aspiration episodes during hospitalization: at the nursing care level (misclassifying patients, transferring tasks to other healthcare professionals and standardizing processes to remove potential threats); at the family level (misclassifying patients, dealing with the cultural relevance of eating) and at the environmental level (positioning the patient, managing time pressures, distracting patient while eating, dealing with food consistency and irritating oral medication). At the hospital level, an adequate nursing workforce and models of care delivery, as well as time for initial and continuing patient and family assessment are required. At the unit level, patient-centred models of care aimed at reducing care standardization are also recommended; in addition, nursing, family and environmental factors should be recorded in the incident reports documenting episodes of aspiration. © The Author 2016.

    Quality of any service is the most important aspect for the manufacturer as well as the consumer. The primary objective of any nation's health system is to provide supreme quality health care services to its patients. The objective of this study was to assess the quality of diagnostic fine needle aspiration cytology service in a tertiary care hospital. As Patient's perspectives provide valuable information on quality of process, therefore, patient's perception in terms of satisfaction with the service was measured. Methods: In this cross sectional analytical study, 291 patients undergoing fine needle aspiration cytology in Mayo Hospital were selected by systematic sampling technique. Information regarding satisfaction of patients with four dimensions of service quality process, namely procedure, sterilization, conduct and competency of doctor was collected through interview on questionnaire. The questionnaire was developed on SERVQUAL model, a measurement tool, for quality assessment of services provided to patients. All items were assessed on 2- point likert scale (0=dissatisfied, 1=satisfied). Frequencies and percentages of satisfied and dissatisfied patients were recorded for each item and all items in each dimension were scored. If the percentage of sum of all item scores of a dimension was =60, the dimension was 'good quality'. Whereas <60% was 'poor quality' dimension. Data was analysed using epi-info-3.5.1. Fisher test was applied to check statistical significance. (p-value <0.05) Results: Out of the 4 dimensions of service quality process, Procedure (48.8%), Sterilization (51.5%) and practitioner conduct (50.9%) were perceived as 'poor' by the patients. Only practitioner competency (67.4%) was perceived as 'good'. Comparison of dimensions of service quality scoring with overall level of patient satisfaction revealed that all 4 dimensions were significantly related to patient dissatisfaction (p<.05) Conclusion: The study suggests that service quality of

    2009-02-01

    Transbronchial needle aspiration (TBNA) is a common method used to collect tissue for diagnosis of different chest diseases and for staging lung cancer, but the procedure has technical limitations. These limitations are mostly related to the difficulty of accurately placing the biopsy needles into the target mass. Currently, pulmonologists plan TBNA by examining a number of Computed Tomography (CT) scan slices before the operation. Then, they manipulate the bronchoscope down the respiratory track and blindly direct the biopsy. Thus, the biopsy success rate is low. The diagnostic yield of TBNA is approximately 70 percent. To enhance the accuracy of TBNA, we developed a TBNA needle with a tip position that can be electromagnetically tracked. The needle was used to estimate the bronchoscope's tip position and enable the creation of corresponding virtual bronchoscopic images from a preoperative CT scan. The TBNA needle was made with a flexible catheter embedding Wang Transbronchial Histology Needle and a sensor tracked by electromagnetic field generator. We used Aurora system for electromagnetic tracking. We also constructed an image-guided research prototype system incorporating the needle and providing a user-friendly interface to assist the pulmonologist in targeting lesions. To test the feasibility of the accuracy of the newly developed electromagnetically-tracked needle, a phantom study was conducted in the interventional suite at Georgetown University Hospital. Five TBNA simulations with a custom-made phantom with a bronchial tree were performed. The experimental results show that our device has potential to enhance the accuracy of TBNA.

    Using a hysteroscope can be simulated on a computer. It will improve physician training by measuring basic knowledge and abilities, allow different interventions and anatomic variations, minimize the trauma of surgical intervention, and reduce operative casualties. An integrated questionnaire covers instrumentation, fluid infusion, power source, indications and preparation for endometrial ablation, surgical techniques, and complications to evaluate the user's knowledge. The operation simulation then proceeds. In the endometrial cavity, by virtual simulation, the operating field should appear in real time to allow physicians to adapt the trajectory of the instruments. The computer is an IBM PC compatible. We use a modified joystick with optical encoders to know the instrument position. The simulation can be repeated as desired. An evaluation system is integrated in the software to keep the user informed on the amount of burn area(s) that have been completed. This prototype model is available.

  14. Management of a large radicular cyst: A non-surgical endodontic approach

    Directory of Open Access Journals (Sweden)

    Shweta Dwivedi

    2014-01-01

    Full Text Available A radicular cyst arises from epithelial remnants stimulated to proliferate by an inflammatory process originating from pulpal necrosis of a non-vital tooth. Radiographically, the classical description of the lesion is a round or oval, well-circumscribed radiolucent image involving the apex of the tooth. A radicular cyst is usually sterile unless it is secondarily infected. This paper presents a case report of conservative non-surgical management of a radicular cyst associated with permanent maxillary right central incisor, right lateral incisor and right canine in a 24-year-old female patient. Root canal treatment was done together with cystic aspiration of the lesion. The lesion was periodically followed up and significant bone formation was seen at the periapical region of affected teeth and at the palate at about 9 months. Thus, nonsurgical healing of a large radicular cyst with palatal swelling provided favorable clinical and radiographic response.

    The purpose of this study was to investigate the effect of a biopsy center-a dedicated space with a dedicated ultrasound machine and technologist, staffed daily by a radiologist responsible for performing ultrasound-guided procedures only-on the rate of non-diagnostic or unsatisfactory thyroid fine-needle aspiration (FNA). Three radiologists performed FNA on 1200 nodules in 998 patients between September 2010 and November 2015. We compared rates of nondiagnostic or unsatisfactory FNA before and after implementation of a biopsy center in September 2014 as part of a quality improvement initiative. Before the establishment of our biopsy center, ultrasound-guided procedures were scheduled between diagnostic studies in the main ultrasound department and were performed by a radiologist responsible for both. Multivariate logistic regression analysis was performed to assess the effect of the biopsy center on the odds of obtaining an adequate sample. Rates of nondiagnostic or unsatisfactory FNA decreased significantly from 15.1% to 8.5% (p < 0.001) after implementation of the biopsy center. The odds of obtaining an adequate sample were higher in the biopsy center (odds ratio, 2.07; 95% CI, 1.43-3.01), even after adjusting for patient age, nodule size, the radiologist performing the procedure, and time over the study period. The implementation of a biopsy center was associated with significantly lower rates of nondiagnostic or unsatisfactory thyroid FNA, suggesting target rates of 10% or lower are achievable with quality improvement measures.

While it is known that metastasis is an inefficient process, the effect of hemodynamic parameters such as fluid shear stress (FSS on the viability and efficacy of metastasis is not well understood. Recent work has shown that select cancer cells may be able to survive and possibly even adapt to FSS in vitro. The current research seeks to characterize the effect of FSS on the mechanical properties of suspended cancer cells in vitro. Nontransformed prostate epithelial cells (PrEC LH and transformed prostate cancer cells (PC-3 were used in this study. The Young's modulus was determined using micropipette aspiration. We examined cells in suspension but not exposed to FSS (unsheared and immediately after exposure to high (6,400 dyn/cm2 and low (510 dyn/cm2 FSS. The PrEC LH cells were ~140% stiffer than the PC-3 cells not exposed to FSS. Post-FSS exposure, there was an increase of ~77% in Young's modulus after exposure to high FSS and a ~47% increase in Young's modulus after exposure to low FSS for the PC-3 cells. There was no significant change in the Young's modulus of PrEC LH cells post-FSS exposure. Our findings indicate that cancer cells adapt to FSS, with an increased Young's modulus being one of the adaptive responses, and that this adaptation is specific only to PC-3 cells and is not seen in PrEC LH cells. Moreover, this adaptation appears to be graded in response to the magnitude of FSS experienced by the cancer cells. This is the first study

    This study aimed to explore the effect of gender on medical students' aspirations. The study design included purposive sampling and interim data interpretation to guide recruitment of medical students with a wide spectrum of opinions. Data were collected through audio-recorded, semi-structured, in-depth exploratory interviews, which were transcribed verbatim. Qualitative analysis was carried out by a female medical student researcher. Her evolving interpretation was constantly compared against the original data by male (doctor) and female (pharmacist) staff researchers in a systematic search for internal corroboration or disconfirmation. Causal associations consistently present in the data are reported. Six male and six female medical students in Years 3 and 4 shared a wish to achieve a work-life balance that allowed them to devote time to bringing up children while contributing usefully to society as doctors. However, women were readier to compromise professional attainment within their personal work-life balances. Their readiness derived from gendered stereotypes of women's social and professional roles, a lack of female professional role models, womens' greater awareness of the tensions between career and family, various other informal social influences, and a lack of positive career advice to counterbalance these influences. Better career advice and more flexible work opportunities are needed if the two-thirds of medical students who are women are to contribute specialist as well as generalist expertise to the medical workforce.

    Peyronie's Disease (PD) remains a challenging and clinically significant morbid condition. Since its first description by François Gigot de la Peyronie, much of the treatment for PD remains nonstandardized. PD is characterized by the formation of fibrous plaques at the level of the tunica albuginea. Clinical manifestations include morphologic changes, such as curvatures and hourglass deformities. Here, we review the common surgical techniques for the management of patients with PD.

    Full Text Available It is important to extract foreign bodies for avoiding life-threatening complications. They can lead to death if they are not treated. Different signs and symptoms could occur according to the complete or partial airway obstruction. Foreign body aspiration is a rare incident in adults. The organic foreign materials such as foods are found to be aspirated more commonly and are usually settled in the right bronchial system. However, dental prosthesis and teeth aspirations are rare in literature. In our study, a 52-year-old male patient who had aspirated the front part of his lower dental prosthesis accidentally is presented and the foreign body is extracted by using rigid bronchoscopy. There are many causes of aspiration but dental prosthetic aspirations should be kept in mind during sleep. For this reason, dental apparatus must be taken out while asleep.

    Full Text Available Small cell lung carcinoma represents a group of highly malignant tumors giving rise to early and widespread metastasis at the time of diagnosis. However, the pancreas is a relatively infrequent site of metastasis by this neoplasm, and there are only occasional reports on its fine needle aspiration (FNA cytology diagnosis. A 66-year-old man presented with extensive mediastinal lymphadenopathy and a mass in the pancreatic tail. Ultrasound-guided FNA smears from the pancreatic mass contained small, round tumor cells with extensive nuclear molding. The cytodiagnosis was metastatic small cell carcinoma. Immunocytochemical staining showed that a variable number of neoplastic cell were positive for cytokeratin, chromogranin A, neurone-specific enolase and synaptophysin but negative for leukocyte common antigen. The trans-bronchial needle aspiration was non-diagnostic, but biopsy was suspicious of a small cell carcinoma. This case represents a rare metastatic lesion in the pancreas from small cell lung carcinoma, diagnosed by FNA cytology.

    Full Text Available Abstract Background The prevalence of obesity among preschool-aged children has increased, especially among those in low-income households. Two promising behavioral targets for preventing obesity include limiting children’s portion sizes and their intake of foods high in solid fats and/or added sugars, but these approaches have not been studied in low-income preschoolers in the home setting. The purpose of this study was to understand the contextual factors that might influence how low-income mothers felt about addressing these behavioral targets and mothers’ aspirations in feeding their children. Methods We recruited 32 English-speaking women in Philadelphia, Pennsylvania who were eligible for the Supplemental Nutrition Assistance Program and who were the biologic mothers of children 36 to 66 months of age. Each mother participated in 1 of 7 focus groups and completed a brief socio-demographic questionnaire. Focus group questions centered on eating occasions, foods and drinks consumed in the home, and portion sizes. Each focus group lasted 90 minutes and was digitally recorded and transcribed verbatim. Three authors independently identified key themes and supporting quotations. Themes were condensed and modified through discussion among all authors. Results Thirty-one mothers identified themselves as black, 15 had a high school education or less, and 22 lived with another adult. Six themes emerged, with three about aspirations mothers held in feeding their children and three about challenges to achieving these aspirations. Mothers’ aspirations were to: 1 prevent hyperactivity and tooth decay by limiting children’s sugar intake, 2 use feeding to teach their children life lessons about limit setting and structure, and 3 be responsive to children during mealtimes to guide decisions about portions. Especially around setting limits with sweets and snacks, mothers faced the challenges of: 1 being nagged by children’s food requests, 2 being

    Full Text Available Laryngotracheoesophageal clefts (LTEC are rare malformations which involve the upper respiratory and digestive tract. Surgical repair should be undertaken promptly to maintain a secure airway and prevent serious pulmonary aspiration. This paper reports the first case of LTEC type 3 with severe laryngotracheomalacia that was brought to Mofid children's hospital in late infancy with a poor health status. Delayed defect correction was our team strategy for the patient when she had achieved good weight gain. At the age of 22 months in collaboration with the pediatric surgical and otolaryngologist team, the repair of the laryngeal cleft was done with lateral open approach method. She was discharged with tracheostomy and gastrostomy. In the next six months follow up after the surgery tracheostomy decannulation and gastrostomy tube removal were done and the infant is now in regular follow-up.

    2010-01-01

    This study aimed to show that SHOX2 DNA methylation is a tumor marker in patients with suspected lung cancer by using bronchial fluid aspirated during bronchoscopy. Such a biomarker would be clinically valuable, especially when, following the first bronchoscopy, a final diagnosis cannot be established by histology or cytology. A test with a low false positive rate can reduce the need for further invasive and costly procedures and ensure early treatment. Marker discovery was carried out by differential methylation hybridization (DMH) and real-time PCR. The real-time PCR based HeavyMethyl technology was used for quantitative analysis of DNA methylation of SHOX2 using bronchial aspirates from two clinical centres in a case-control study. Fresh-frozen and Saccomanno-fixed samples were used to show the tumor marker performance in different sample types of clinical relevance. Valid measurements were obtained from a total of 523 patient samples (242 controls, 281 cases). DNA methylation of SHOX2 allowed to distinguish between malignant and benign lung disease, i.e. abscesses, infections, obstructive lung diseases, sarcoidosis, scleroderma, stenoses, at high specificity (68% sensitivity [95% CI 62-73%], 95% specificity [95% CI 91-97%]). Hypermethylation of SHOX2 in bronchial aspirates appears to be a clinically useful tumor marker for identifying subjects with lung carcinoma, especially if histological and cytological findings after bronchoscopy are ambiguous

    Barium contrast radiography is a conventional procedure aimed at revealing lesions of the alimentary tract using barium sulfate on X-ray irradiation. Although it is widely used in clinics, adverse effects and complications are observed, such as anaphylaxis, granuloma, fecalithes, abdomen-leaking, embolism, bacterial contamination, and aspiration. We report a case of death due to a massive barium sulfate aspiration resulted from an air-barium double contrast enema radiography. A 25-year-old female patient was hospitalized with symptoms of abdominal distention, nausea, vomiting and diarrhea for three days. A progressive respiratory distress presented only 1h after a small bowel air-barium double contrast enema. The patient died 11h later. The result of autopsy revealed the cause of death to be severe chemical pneumonitis induced by gastric fluid which was aspirated into her lungs. Barium sulfate is generally recognized to be chemically inert for the respiratory system, but a mixture of barium sulfate with gastric contents is fatal. Here we intend to suggest that, when determining the potential cause of death, medical examiners should consider a patient's status quo as well as the possible adverse effects and complications caused by the barium sulfate preparation during gastrointestinal radiography.

    2012-09-01

    The aim of this study was to compare the efficacy of endometrial aspiration biopsy (EAB) with the more traditional dilatation and curettage (D&C) for the procurement of lymphoid progenitor cells and uterine natural killer (NK) populations in endometrial tissue. This prospective observational study conducted in a tertiary referral university hospital examined endometrium obtained from 32 women admitted for laparoscopic gynaecological procedures. Each participant had endometrium sampled using both EAB and D&C. Both methods were assessed as a source of uterine NK and lymphoid progenitor cells. Similar proportions of mature CD45+CD56+ NK cells (range 25.4-36.2%) and CD45+CD34+ lymphoid progenitors (range 1.2-2.0%) were found in tissue obtained using both EAB and D&C. These cells were adequate for flow cytometric analysis, magnetic bead separation and culture. Colony formation by the CD34+ population demonstrated maturational potential. Tissues obtained via endometrial biopsy and D&C are equivalent, by analysis of uterine NK and lymphoid progenitor cells. The aim of this study was to compare two methods of endometrial sampling - endometrial aspiration biopsy and traditional dilatation and curettage - for the procurement of haematopoietic stem cells and uterine natural killer (NK) populations in endometrial tissue. Thirty-two women who had gynaecological procedures in a tertiary referral hospital participated in this study and had endometrial tissue collected via both methods. Similar populations of mature NK cells and haematopoietic stem cells were found in tissue obtained using both endometrial aspiration biopsy and dilatation and curettage. Tissue obtained via endometrial aspiration biopsy was adequate for the culture and growth of haematopoietic stem cells. We conclude that tissue obtained via endometrial biopsy and dilatation and curettage is equivalent, by analysis of uterine NK and haematopoietic stem cells using flow cytometry. This has implications for further

    Full Text Available A rare case of extra medullary plasmacytoma (EMP of thyroid gland in a 60 year old male, occurring against a background of Hashimoto′s thyroiditis is reported. The fine needle aspiration cytology (FNAC initially done as an outpatient procedure, showed atypical epithelial cells on a background of amyloid. Considering these findings we gave a diagnosis of medullary carcinoma. Histology of the total thyroidectomy specimen showed an extensive infiltration of neoplastic plasma cells against a background of Hashimoto′s thyroiditis, with a bizarre Hurthle cell change. Immunohistochemistry on the histology sections confirmed the diagnosis of solitary plasmacytoma of thyroid against a background of Hashimoto′s thyroiditis.

    2015-12-01

    TBNA through the flexible bronchoscope is a 37-year-old technology that utilizes a TBNA needle to puncture the bronchial wall and obtain specimens of peribronchial and mediastinal lesions through the flexible bronchoscope for the diagnosis of benign and malignant diseases in the mediastinum and lung. Since 2002, the Olympus Company developed the first generation ultrasound equipment for use in the airway, initially utilizing an ultrasound probe introduced through the working channel followed by incoroporation of a fixed linear ultrasound array at the distal tip of the bronchoscope. This new bronchoscope equipped with a convex type ultrasound probe on the tip was subsequently introduced into clinical practice. The convex probe (CP)-EBUS allows real-time endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) of mediastinal and hilar lymph nodes. EBUS-TBNA is a minimally invasive procedure performed under local anesthesia that has been shown to have a high sensitivity and diagnostic yield for lymph node staging of lung cancer. In 10 years of EBUS development, the Olympus Company developed the second generation EBUS bronchoscope (BF-UC260FW) with the ultrasound image processor (EU-M1), and in 2013 introduced a new ultrasound image processor (EU-M2) into clinical practice. FUJI company has also developed a curvilinear array endobronchial ultrasound bronchoscope (EB-530 US) that makes it easier for the operator to master the operation of the ultrasonic bronchoscope. Also, the new thin convex probe endobronchial ultrasound bronchoscope (TCP-EBUS) is able to visualize one to three bifurcations distal to the current CP-EBUS. The emergence of EBUS-TBNA has also been accompanied by innovation in EBUS instruments. EBUS elastography is, then, a new technique for describing the compliance of structures during EBUS, which may be of use in the determination of metastasis to the mediastinal and hilar lymph nodes. This article describes these new EBUS

    Surgical removal plays an important role in treating children's craniopharyngioma. For a safe and minimally invasive craniotomy, a reformed surgical modality was proposed in this paper by combining the insertion of an Ommaya reservoir system (ORS) by stereotactic puncture, aspiration of cystic fluid in 2-day interval for consecutive 7-10 days, and the delayed tumor resection. Eleven patients (aged from 5 to 9 years old) with giant cystic craniopharyngiomas who had undergone the reformed surgical modality during November 2014 and December 2015 were collected as group A. In contrast, seven patients (aged from 5 to 11 years old) who had undergone the traditional directed operation without any prior management from January 2014 to October 2014 were collected into group B. A retrospective analysis was performed for both groups at one institution. The preoperative and postoperative clinical presentations, neuroimaging, early postoperative outcome, and the surgery-related complications of both groups were reviewed. For group A, the mean value of the maximum tumor diameters shank from 52.36 to 23.82 mm after implementing aspiration of the cystic fluid in 1-day interval for consecutive 8.23 days. Eight patients (72.73%) in group A underwent a gross total resection (GTR), while two (28.57%) patients underwent GTR in group B. The postoperative electrolyte disturbance rate and endocrine disorder rate of group B were significantly higher than those of group A (42.86 vs 36.36%; 71.43 vs 45.45%). Postoperative long-term diabetes insipidus only occurred in one patient of group B, and postoperative visual deterioration occurred in two patients of group B. Besides, one patient of group B died of severe postoperative hypothalamus dysfunction. Patients with residual tumors were applied with additional adjuvant radiotherapy, and no recurrence was observed in follow-up examinations. A favorable outcome can be achieved by combining the insertion of an ORS by stereotactic puncture

    Cleft lip and palate repair requires a deep and small surgical field and is usually performed by surgeons wearing surgical loupes. Surgeons with loupes can obtain a wider surgical view, although headlights are required for the deepest procedures. Surgical microscopes offer comfort and a clear and magnification-adjustable surgical site that can be shared with the whole team, including observers, and easily recorded to further the education of junior surgeons. Magnification adjustments are convenient for precise procedures such as muscle dissection of the soft palate. We performed a comparative investigation of 18 cleft operations that utilized either surgical loupes or microscopy. Paper-based questionnaires were completed by staff nurses to evaluate what went well and what could be improved in each procedure. The operating time, complication rate, and scores of the questionnaire responses were statistically analyzed. The operating time when microscopy was used was not significantly longer than when surgical loupes were utilized. The surgical field was clearly shared with surgical assistants, nurses, anesthesiologists, and students via microscope-linked monitors. Passing surgical equipment was easier when sharing the surgical view, and preoperative microscope preparation did not interfere with the duties of the staff nurses. Surgical microscopy was demonstrated to be useful during cleft operations.

    It has been suggested that both performance and academic well-being play a role in adolescent students' educational attainment and school dropout. In this study, we therefore examined, first, what kinds of academic well-being (i.e., school burnout, schoolwork engagement, and mathematics self-concept) and mathematics performance profiles can be identified among lower secondary school students ( N grade 7 = 583, N grade 9 = 497); second, how stable these profiles are across one school year during the seventh and ninth grades; and, third, how students with different academic well-being and mathematics performance profiles differ with respect to their educational aspirations. By means of latent profile analyses, three groups of students in seventh grade: thriving (34%), average (51%), and negative academic well-being (15%) and four groups of students in ninth grade: thriving (25%), average (50%), negative academic well-being (18%), and low-performing (7%) with distinct well-being and mathematics performance profiles were identified. Configural frequency analyses revealed that the profiles were relatively stable across one school year; 60% of the students displayed identical profiles over time. The thriving students reported the highest educational aspirations compared to the other groups. In addition, the low-performing students in the ninth grade had the lowest educational aspirations just before the transition to upper secondary school. Practical implications as well as directions for future research are discussed.

    Full Text Available The Malaysia Education Development Plan (2013 – 2025 (pre-school to post-secondary education was launched by the Ministry of Education on October 2011. This plan aimed at transforming the national education system holistically and was based upon the international standard to instil the national aspiration and to prepare the students with sufficient competitive edge when upon completion of their study. This paper reviewed the six aspirations outlined in the Malaysia Education Development Plan which encompassed knowledge, thinking skills, leadership skills, bilingual skills, ethics and spirituality, and national identity. Each of these elements provide a holistic approach in ensuring the students are well equipped not only with knowledge and soft skills, but most instrumentally they are able to engulf the spirit of national identity. This is highly important in today’s world as without it, the country would not be able to move forward with its Vision 2020 when the people are not united and prepared to strive for excellence. This paper discovered that the six aspirations listed in the Malaysia Education Development Plan are embedded strategically in each of the thrust in developing the new generation of students.

    Full Text Available It has been suggested that both performance and academic well-being play a role in adolescent students’ educational attainment and school dropout. In this study, we therefore examined, first, what kinds of academic well-being (i.e., school burnout, schoolwork engagement, and mathematics self-concept and mathematics performance profiles can be identified among lower secondary school students (Ngrade 7 = 583, Ngrade 9 = 497; second, how stable these profiles are across one school year during the seventh and ninth grades; and, third, how students with different academic well-being and mathematics performance profiles differ with respect to their educational aspirations. By means of latent profile analyses, three groups of students in seventh grade: thriving (34%, average (51%, and negative academic well-being (15% and four groups of students in ninth grade: thriving (25%, average (50%, negative academic well-being (18%, and low-performing (7% with distinct well-being and mathematics performance profiles were identified. Configural frequency analyses revealed that the profiles were relatively stable across one school year; 60% of the students displayed identical profiles over time. The thriving students reported the highest educational aspirations compared to the other groups. In addition, the low-performing students in the ninth grade had the lowest educational aspirations just before the transition to upper secondary school. Practical implications as well as directions for future research are discussed.

    Full Text Available The treatment modalities for odontomas are generally depend on the tumors size. Small and medium lesions can usually be removed easily allowing preservation of surrounding anatomical structures. In our study, we reported a conservative surgical treatment of a large complex odontoma. A 19-year-old woman was referred to our clinic after an incidentally observed lesion on her right mandibular angle. The patient was symptom-free at the time of visit. Computed tomography (CT images showed a mass with a size of 3.5 cm x 3 cm x 2 cm. CT sections and tridimensional images showed partially eroded buccal and lingual cortex. Surgical treatment was indicated with an initial diagnosis of compound odontoma. The lesion removed after sectioning with bur and maxillo-mandibular fixation (MMF were not thought to be necessary while the buccal and lingual cortexes were mostly reliable for preventing a fracture. In our case, the size of the odontoma was suitable for a conservative treatment method and with this modality we managed to prevent a possible fracture and eliminate the disadvantages of MMF.

    To test the effects of high-frequency percussive ventilation (HFPV) compared with high-frequency oscillatory ventilation (HFOV) and low-volume conventional mechanical ventilation (LVCMV), on lung injury course in a gastric juice aspiration model. Prospective, randomized, controlled, in-vivo animal study. University animal research laboratory. Forty-three New Zealand rabbits. Lung injury was induced by intratracheal instillation of human gastric juice in order to achieve profound hypoxaemia (PaO2/FIO2ventilated for 4h after randomization in one of the following four groups: HFPV (median pressure 15cmH2O); LVCMV (VT 6mlkg(-1) and PEEP set to reach 15cmH2O plateau pressure); HFOV (mean pressure 15cmH2O); and a high-volume control group HVCMV (VT 12ml kg(-1) and ZEEP). Static respiratory compliance increased after the ventilation period in the HFPV, LVMCV and HFOV groups, in contrast with the HVCMV group. PaO2/FIO2 improved similarly in the HFPV, LVCMV and HFOV groups, and remained lower in the HVCMV group than in the three others. Lung oedema, myeloperoxidase and histological lung injury score were higher in the HVCMV group, but not different among all others. Arterial lactate markedly increased after 4h of ventilation in the HVCMV group, while lower but similar levels were observed in the three other groups. HFPV, like HFOV and protective CMV, improves respiratory mechanics and oxygenation, and attenuates lung damage. The HFPV provides attractive lung protection, but further studies should confirm these results before introducing HFPV into the clinical arena.

    A detailed understanding of renal surgical anatomy is necessary to optimize preoperative planning and operative technique and provide a basis for improved outcomes. To evaluate the literature regarding pertinent surgical anatomy of the kidney and related structures, nephrometry scoring systems, and current surgical strategies for partial nephrectomy (PN). A literature review was conducted. Surgical renal anatomy fundamentally impacts PN surgery. The renal artery divides into anterior and posterior divisions, from which approximately five segmental terminal arteries originate. The renal veins are not terminal. Variations in the vascular and lymphatic channels are common; thus, concurrent lymphadenectomy is not routinely indicated during PN for cT1 renal masses in the setting of clinically negative lymph nodes. Renal-protocol contrast-enhanced computed tomography or magnetic resonance imaging is used for standard imaging. Anatomy-based nephrometry scoring systems allow standardized academic reporting of tumor characteristics and predict PN outcomes (complications, remnant function, possibly histology). Anatomy-based novel surgical approaches may reduce ischemic time during PN; these include early unclamping, segmental clamping, tumor-specific clamping (zero ischemia), and unclamped PN. Cancer cure after PN relies on complete resection, which can be achieved by thin margins. Post-PN renal function is impacted by kidney quality, remnant quantity, and ischemia type and duration. Surgical renal anatomy underpins imaging, nephrometry scoring systems, and vascular control techniques that reduce global renal ischemia and may impact post-PN function. A contemporary ideal PN excises the tumor with a thin negative margin, delicately secures the tumor bed to maximize vascularized remnant parenchyma, and minimizes global ischemia to the renal remnant with minimal complications. In this report we review renal surgical anatomy. Renal mass imaging allows detailed delineation of the

    Surgical skills training varies greatly between institutions and is often left to students to approach independently. Although many studies have examined single interventions of skills training, no data currently exists about the implementation of surgical skills assessment as a component of the medical student surgical curriculum. We created a technical skills competition and evaluated its effect on student surgical skill development. Second-year medical students enrolled in the surgery clerkship voluntarily participated in a surgical skills competition consisting of knot tying, laparoscopic peg transfer, and laparoscopic pattern cut. Winning students were awarded dinner with the chair of surgery and a resident of their choice. Individual event times and combined times were recorded and compared for students who completed without disqualification. Disqualification included compromising cutting pattern, dropping a peg out of the field of vision, and incorrect knot tying technique. Timed performance was compared for 2 subsequent academic years using Mann-Whitney U test. Overall, 175 students competed and 71 students met qualification criteria. When compared by academic year, 2015 to 2016 students (n = 34) performed better than 2014 to 2015 students (n = 37) in pattern cut (133s vs 167s, p = 0.040), peg transfer (66s vs 101s, p skills competition improves student technical performance. Further research is needed regarding long-term benefits of surgical competitions for medical students. Copyright © 2017 Association of Program Directors in Surgery. Published by Elsevier Inc.

    The role of space suits in the prevention of orthopedic prosthetic joint infection remains unclear. Recent evidence suggests that space suits may in fact contribute to increased infection rates, with bioaerosol emissions from space suits identified as a potential cause. This study aimed to compare the particle and microbiological emission rates (PER and MER) of space suits and standard surgical clothing. A comparison of emission rates between space suits and standard surgical clothing was performed in a simulated surgical environment during 5 separate experiments. Particle counts were analyzed with 2 separate particle counters capable of detecting particles between 0.1 and 20 μm. An Andersen impactor was used to sample bacteria, with culture counts performed at 24 and 48 hours. Four experiments consistently showed statistically significant increases in both PER and MER when space suits are used compared with standard surgical clothing. One experiment showed inconsistent results, with a trend toward increases in both PER and MER when space suits are used compared with standard surgical clothing. Space suits cause increased PER and MER compared with standard surgical clothing. This finding provides mechanistic evidence to support the increased prosthetic joint infection rates observed in clinical studies. Copyright © 2017 Elsevier Inc. All rights reserved.

    The impact of surgical site infection (SSI) is substantial. Although previous study has determined relative risk and odds ratio (OR) values to quantify risk factors, these values may be difficult to translate to the patient during counseling of surgical options. Ideally, a model that predicts absolute risk of SSI, rather than relative risk or OR values, would greatly enhance the discussion of safety of spine surgery. To date, there is no risk stratification model that specifically predicts the risk of medical complication. The purpose of this study was to create and validate a predictive model for the risk of SSI after spine surgery. This study performs a multivariate analysis of SSI after spine surgery using a large prospective surgical registry. Using the results of this analysis, this study will then create and validate a predictive model for SSI after spine surgery. The patient sample is from a high-quality surgical registry from our two institutions with prospectively collected, detailed demographic, comorbidity, and complication data. An SSI that required return to the operating room for surgical debridement. Using a prospectively collected surgical registry of more than 1,532 patients with extensive demographic, comorbidity, surgical, and complication details recorded for 2 years after the surgery, we identified several risk factors for SSI after multivariate analysis. Using the beta coefficients from those regression analyses, we created a model to predict the occurrence of SSI after spine surgery. We split our data into two subsets for internal and cross-validation of our model. We created a predictive model based on our beta coefficients from our multivariate analysis. The final predictive model for SSI had a receiver-operator curve characteristic of 0.72, considered to be a fair measure. The final model has been uploaded for use on SpineSage.com. We present a validated model for predicting SSI after spine surgery. The value in this model is that it gives

    To evaluate the effectiveness of the reaspiration or rebiopsy of pulmonary lesions (second PCNA) in cases where the pathologic results are inconclusive upon initial percutaneous needle aspiration biopsy (PCNA). A total of 364 PCNA cases (350 initial PCNA, 14 second PCNA) were performed under CT or fluoroscopy guidance for all the 350 patients enrolled. The procedure was performed by either using an automated biopsy gun with a 20-G needle (298 cases) or a 20-G aspiration needle (66 cases). The pathologic agreement rates between the initial and second PCNA, as well as the causes for a second PCNA, were evaluated. Finally the type and rate of complication were also evaluated. The second PCNA rate was 4.0% (14/350). The causes for a second PCNA, following the initial PCNA included unexpected pathologic results (n = 7) and inconclusive pathologic results (n = 7). Of the seven cases which had unexpected pathologic results from their initial PCNAs, five had similar pathologic results after a second PCNA. Also, of the seven cases of inconclusive pathologic results, such as atypical cells, the scanty cellularity or necrosis upon an initial PCNA, six cases revealed a malignancy on a second PCNA. The overall complication rate, including both the initial and second PCNAs was 14.0% (51/364). A second PCNA was performed to help resolve the exact diagnosis for a pulmonary lesion in cases of inconclusive pathologic results upon an initial PCNA

  15. The Role of Aspiration Level in Risky Choice: A Comparison of Cumulative Prospect Theory and SP/A Theory.

    Lopes; Oden

    1999-06-01

    In recent years, descriptive models of risky choice have incorporated features that reflect the importance of particular outcome values in choice. Cumulative prospect theory (CPT) does this by inserting a reference point in the utility function. SP/A (security-potential/aspiration) theory uses aspiration level as a second criterion in the choice process. Experiment 1 compares the ability of the CPT and SP/A models to account for the same within-subjects data set and finds in favor of SP/A. Experiment 2 replicates the main finding of Experiment 1 in a between-subjects design. The final discussion brackets the SP/A result by showing the impact on fit of both decreasing and increasing the number of free parameters. We also suggest how the SP/A approach might be useful in modeling investment decision making in a descriptively more valid way and conclude with comments on the relation between descriptive and normative theories of risky choice.

    2012-01-31

    BACKGROUND: In Ireland, specialist paediatric surgery is carried out in paediatric hospitals in Dublin. General surgeons\\/consultants in other surgical specialities provide paediatric surgical care in regional centres. There has been a failure to train general surgeons with paediatric skills to replace these surgeons upon retirement. AIM: To assess paediatric surgical workload in one regional centre to focus the debate regarding the future provision of general paediatric surgery in Ireland. METHODS: Hospital in-patient enquiry (HIPE) system was used to identify total number of paediatric surgical admissions and procedures. Cases assessed requiring hospital transfer. RESULTS: Of 17,478 surgical patients treated, 2,584 (14.8%) were under 14 years. A total of 2,154 procedures were performed. CONCLUSION: Regional centres without dedicated paediatric surgeons deliver care to large numbers of paediatric patients. The demand for care highlights the need for formal paediatric services\\/appropriate surgical training for general surgical trainees.

    1998-01-01

    The purpose of this study is to compare the efficacy and safety of CT-guided automated gun biopsy with those of fine needle aspiration biopsy of pulmonary lesions. Under CT guidance, we performed automated gu biopsies in 115 cases of 109 patients and fine needle aspiration biopsies in 119 cases of 108 patients with pulmonary lesions. Between the two methods, we compared the diagnostic rate, diagnostic accuracy and frequency of compilations according to the depth and diameter of pulmonary lesions. The overall diagnostic rates of automated gun biopsy and fine needle aspiration biopsy were 76.5 % (88/115) and 64.7 % (77/119) respectively. There was a significant statistical difference (p=0.048), especially in the case of malignant lesions less than 3 cm (p=0.027) and more than 6 cm in maximal diameter (p=0.008), and in the lesions located from 1 cm to less than 3 cm from the pleural (p=0.030), as seen on CT. There was no significant statistical difference in the frequency of complications. Automated gun biopsy of pulmonary lesions under CT guidance is safe, with complications rate comparable to those of fine needle aspiration biopsy. A higher overall diagnostic rate can be achieved by automated gun biopsy than by fine needle aspiration biopsy. For the diagnosis of pulmonary lesions under CT guidance, automated gun biopsy is therefore a more useful procedure than fine needle aspiration biopsy. (author). 24 refs., 3 tabs

    To discover the level of interest in a surgical career amongst junior doctors and trainee interns in the Auckland region. Secondary aims are to identify the factors that influence career choice as well as the timing of career choice. An anonymous and structured questionnaire was distributed to all trainee interns and junior doctors in their first to fifth postgraduate years in the Auckland region. Questions were based on basic demographics, level of training, career preference and factors from previous experiences in surgery that may have influenced their career choice. Total of 87 replies with 36% expressed interest in surgery whereas 64% were interested in non-surgical specialties. Top three factors influencing career choice were similar in both groups: Lifestyle, career ambitions and family. Personal interest, practical hands-on and positive previous experiences were the top reasons why junior doctors chose surgery. Poor lifestyle, lacking of interest, limited future part-time work and previous negative experiences were the top reasons why junior doctors did not choose surgery. A significantly (pcareers earlier. Career aspirations of New Zealand junior doctors were similar to findings reported overseas. To promote surgery amongst junior doctors and medical students, attention should be paid to the key factors which may influence career choice. By improving working conditions and have better surgical education with good mentoring, team atmosphere and opportunities for early exposure will hopefully allow better recruitment and training of future surgeons.

    Full Text Available This paper provides a novel algorithm to attain the independent navigation of a colonoscopy surgical endoscope. First, it introduces a brief description of this issue through the scientist advance for medical robotics. It then makes a quickly count of the existent methods and at the end it provides the basis in order to propose a new alternative solution with help from vision-guidance. That means that images will be processed and interpreted with the purpose of maintaining the endoscope always at the intestine center. All this considered will help us to reduce colonoscopy surgeries consequences and the most important advantage of this new method proposed is that surgeons will accomplish their work easier and more efficiently.

    Amebic liver abscess (ALA) is a common and serious problem in our country. There are only a few controlled trials on the efficacy and advantages of combination therapy with percutaneous needle aspiration and pharmacotherapy, over pharmacotherapy alone for amebic liver abscess. This study was conducted to compare the efficacy of two different treatment modalities i.e. drug treatment alone vs. drug treatment and aspiration of abscess cavity in patients with small (up to 5 cm) and large (5 cm to 10 cm) size ALA. This is one of the largest single center, prospective, randomized studies comparing the efficacy of aspiration in ALA. (i) Mean body temperature, liver tenderness, total leukocyte count (TLC), serum alanine aminotransferase (ALT) and liver span were significantly decreased in the aspiration group on days 8 and 15 as compared to non-aspiration group especially in large abscess (5 cm to 10 cm). (ii) Abscess cavity maximum diameter decreased significantly in aspiration group on days 8 and 15, and 1 month & 3 months in large abscess (5cm to 10 cm). (i) Needle aspiration along with metronidazole hastens clinical improvement especially in large (5 cm up to 10 cm) cavities in patients with ALA. (ii) Aspiration is safe and no major complications occurred. (iii) Hence, combination therapy should be the first choice especially in large ALA (5 cm to 10 cm).

    The significant global variations in surgical oncology training paradigms can have a detrimental effect on tackling the rising global cancer burden. While some variations in training are essential to account for the differences in types of cancer and biology, the fundamental principles of providing care to a cancer patient remain the same. The development of a global curriculum in surgical oncology with incorporated essential standards could be very useful in building an adequately trained surgical oncology workforce, which in turn could help in tackling the rising global cancer burden. The leaders of the Society of Surgical Oncology and European Society of Surgical Oncology convened a global curriculum committee to develop a global curriculum in surgical oncology. A global curriculum in surgical oncology was developed to incorporate the required domains considered to be essential in training a surgical oncologist. The curriculum was constructed in a modular fashion to permit flexibility to suit the needs of the different regions of the world. Similarly, recognizing the various sociocultural, financial and cultural influences across the world, the proposed curriculum is aspirational and not mandatory in intent. A global curriculum was developed which may be considered as a foundational scaffolding for training surgical oncologists worldwide. It is envisioned that this initial global curriculum will provide a flexible and modular scaffolding that can be tailored by individual countries or regions to train surgical oncologists in a way that is appropriate for practice in their local environment.

    The goal of this systematic review by the American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee was to derive recommendations from the medical literature regarding the surgical treatment of pediatric gastroesophageal reflux disease (GERD). Five questions were addressed by searching the MEDLINE, Cochrane, Embase, Central, and National Guideline Clearinghouse databases using relevant search terms. Consensus recommendations were derived for each question based on the best available evidence. There was insufficient evidence to formulate recommendations for all questions. Fundoplication does not affect the rate of hospitalization for aspiration pneumonia, apnea, or reflux-related symptoms. Fundoplication is effective in reducing all parameters of esophageal acid exposure without altering esophageal motility. Laparoscopic fundoplication may be comparable to open fundoplication with regard to short-term clinical outcomes. Partial fundoplication and complete fundoplication are comparable in effectiveness for subjective control of GERD. Fundoplication may benefit GERD patients with asthma, but may not improve outcomes in patients with neurologic impairment or esophageal atresia. Overall GERD recurrence rates are likely below 20%. High-quality evidence is lacking regarding the surgical management of GERD in the pediatric population. Definitive conclusions regarding the effectiveness of fundoplication are limited by patient heterogeneity and lack of a standardized outcomes reporting framework.

    Teaching of surgery has been affected by many factors over the last years, such as the reduction of working hours, the optimization of the use of the operating room or patient safety. Traditional teaching methodology fails to reduce the impact of these factors on surgeońs training. Simulation as a teaching model minimizes such impact, and is more effective than traditional teaching methods for integrating knowledge and clinical-surgical skills. Simulation complements clinical assistance with training, creating a safe learning environment where patient safety is not affected, and ethical or legal conflicts are avoided. Simulation uses learning methodologies that allow teaching individualization, adapting it to the learning needs of each student. It also allows training of all kinds of technical, cognitive or behavioural skills. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    Past studies have shown that women with abnormal cytology or epithelial cells in nipple aspirate fluid (NAF) have an increased relative risk (RR) of breast cancer when compared to women from whom NAF was attempted but not obtained (non-yielders). This study analyzed NAF results from a group of women seen in a breast clinic between 1970–1991 (N = 2480). Our analysis presented here is an aggregate of two sub-groups: women with questionnaire data (n = 712) and those with NAF visits beginning in 1988 (n = 238), the year in which cancer case information was uniformly collected in California. Cytological classification was determined for a group of 946 women using the most abnormal epithelial cytology observed in fluid specimens. Breast cancer incidence and mortality status was determined through June 2006 using data from the California Cancer Registry, California Vital Statistics and self-report. We estimated odd ratios (ORs) for breast cancer using logistic regression analysis, adjusting for age. We analyzed breast cancer risk related to abnormality of NAF cytology using non-yielders as the referent group and breast cancer risk related to the presence or absence of epithelial cells in NAF, using non-yielders/fluid without epithelial cells as the referent group. Overall, 10% (93) of the 946 women developed breast cancer during the follow-up period. Age-adjusted ORs and 95% confidence intervals (C.I.) compared to non-yielders were 1.4 (0.3 to 6.4), 1.7 (0.9 to 3.5), and 2.0 (1.1 to 3.6) for women with fluid without epithelial cells, normal epithelial cells and hyperplasia/atypia, respectively. Comparing the presence or absence of epithelial cells in NAF, women with epithelial cells present in NAF were more likely to develop breast cancer than non-yielders or women with fluid without epithelial cells (RR = 1.9, 1.2 to 3.1). These results support previous findings that 1) women with abnormal epithelial cells in NAF have an increased risk of breast cancer when compared to

    Just like simulators are a standard in aviation and aerospace sciences, we expect for surgical simulators to soon become a standard in medical applications. These will correctly instruct future doctors in surgical techniques without there being a need for hands on patient instruction. Using virtual reality by digitally transposing surgical procedures changes surgery in are volutionary manner by offering possibilities for implementing new, much more efficient, learning methods, by allowing the practice of new surgical techniques and by improving surgeon abilities and skills. Perfecting haptic devices has opened the door to a series of opportunities in the fields of research,industry, nuclear science and medicine. Concepts purely theoretical at first, such as telerobotics, telepresence or telerepresentation,have become a practical reality as calculus techniques, telecommunications and haptic devices evolved,virtual reality taking a new leap. In the field of surgery barrier sand controversies still remain, regarding implementation and generalization of surgical virtual simulators. These obstacles remain connected to the high costs of this yet fully sufficiently developed technology, especially in the domain of haptic devices. Celsius.

    Full Text Available Background: The frequency of encountering radiodermatitis caused by X-ray fluoroscopic procedures for ischaemic heart disease is increasing. In severe cases, devastating ulcers with pain, for which conservative therapy is ineffective, emerge. Radiation-induced ulcers are notorious for being difficult to treat. Simple skin grafting often fails because of the poor state of the wound bed. A vascularized flap is a very good option. However, the non-adherence of the well-vascularized flap with the irradiated wound bed is frequently experienced. Aim: To ameliorate the irradiated wound bed, bone marrow-derived platelet-rich plasma (bm-PRP was delivered during the surgery. Materials and Methods: Four patients with severe cutaneous radiation injury accompanied by unbearable pain after multiple fluoroscopic procedures for ischaemic heart disease were treated. Wide excision of the lesion and coverage with a skin flap supplemented with bm-PRP injection was performed. Results: All patients obtained wound closure and were relieved from pain. No complication concerning the bone marrow aspiration and delivery of bm-PRP was observed. Conclusions: Supplementation of bm-PRP can be an option without major complications, time, and cost to improve the surgical outcome for irradiated wounds.

    Full Text Available Melanoma is one of the most aggressive malignant skin neoplasms worldwide with more than 20% of world melanoma seen in black Africa and Asia. Late presentation due to ignorance, poverty, and lack of adequate health facility in Nigeria is always the norms. We present this case report because of precision in diagnosis, using fine needle aspiration cytology (FNAC to reemphasize that the technique is cheap, cost effective, and quick that can reduce the burden of incisional biopsy before definitive surgery and improve early detection of the disease especially in developing countries.

    2009-11-01

    Full Text Available Abstract Introduction Invasive pulmonary aspergillosis is the most common form of infection by Aspergillus species among immunocompromised patients. Although this infection frequently involves the lung parenchyma, it is unusual to find it limited to the tracheobronchial tree, a condition known as invasive aspergillus tracheobronchitis. Case presentation A 65 year-old Hispanic man from Bolivia with a history of chronic lymphocytic leukemia developed cough and malaise eight months after having an allogenic stem cell transplant. A computed tomography of the chest revealed an area of diffuse soft tissue thickening around the left main stem bronchus, which was intensely fluorodeoxyglucose-avid on positron emission tomography scanning. An initial bronchoscopic exam revealed circumferential narrowing of the entire left main stem bronchus with necrotic and friable material on the medial wall. Neither aspirates from this necrotic area nor bronchial washing were diagnostic. A second bronchoscopy with endobronchial ultrasound evidenced a soft tissue thickening on the medial aspect of the left main stem bronchus underlying the area of necrosis visible endoluminally. Endobronchial ultrasound-guided transbronchial needle aspiration performed in this area revealed multiple fungal elements suggestive of Aspergillus species. Conclusion We describe the first case of invasive aspergillus tracheobronchitis in which the diagnosis was facilitated by the use of endobronchial ultrasound guided trans-bronchial needle aspiration. To the best of our knowledge, we are also presenting the first positron emission tomography scan images of this condition in the literature. We cautiously suggest that endobronchial ultrasound imaging may be a useful tool to evaluate the degree of invasion and the involvement of vascular structures in these patients prior to bronchoscopic manipulation of the affected areas in an effort to avoid potentially fatal hemorrhage.

    2008-04-01

    Selection for surgical training in Australia is currently based on assessment of a structured curriculum vitae, referral reports from selected clinicians and an interview. The formal assessment of laparoscopic psychomotor skill and ability to attain skills is not currently a prerequisite for selection. The aim of this study was to assess the innate psychomotor skills of interns and also to compare interns with an interest in pursuing a surgical career to interns with those with no interest in pursuing a surgical career. Twenty-two interns were given the opportunity to carry out tasks on the Minimal Invasive Surgical Trainer, Virtual Reality (Mentice, Gothenburg, Sweden) Simulator. The candidates were required to complete six tasks, repeated six times each. Scores for each task were calculated objectively by the simulator software. Demographic data were similar between the two groups. Although some candidates who were interested in pursuing a surgical career performed poorly on the simulator, there was no significant difference when comparing the two groups. The Minimal Invasive Surgical Trainer, Virtual Reality (Mentice) Simulator provides an objective and comparable assessment of laparoscopic psychomotor skills. We can conclude that interns have varying inherent ability as judged by the simulator and this does not seem to have an influence on their career selection. There was no significant difference in the scores between the two groups. Interns with and without inherent abilities have aspirations to pursue surgical careers and their aptitude does not seem to influence this decision. Surgical colleges could use psychomotor ability assessments to recruit candidates to pursue a career in surgery. Trainees needing closer monitoring and additional training could be identified early and guided to achieve competency.

    Full Text Available Presence of endometrial glands and stroma in places other than the uterus is called endometriosis. It can be pelvic or extra-pelvic. Abdominal scar endometriosis is an extra-pelvic endometriosis that can occur after surgery involving the uterus. Post-caesarean section, scar endometriosis is a rare event. The diagnosis is frequently made only after excision of disease tissue. We present a case of post-caesarean section abdominal scar endometriosis presenting as a tumor on the abdominal wall, which was diagnosed by fine needle aspiration cytology and confirmed by cell block preparation.

    2015-01-01

    Ultrasound (US)-guided fine needle aspiration (US-FNA) has played a crucial role in managing patients with thyroid nodules, owing to its safety and accuracy. However, even with US guidance, nondiagnostic sampling and infrequent complications still occur after FNA. Accordingly, the Task Force on US-FNA of the Korean Society of Thyroid Radiology has provided consensus recommendations for the US-FNA technique and related issues to improve diagnostic yield. These detailed procedures are based on a comprehensive analysis of the current literature and from the consensus of experts.

    Full Text Available Primary giant cell tumors of soft tissues (GCT-ST are extremely rare soft tissue tumors, located in both superficial and deep soft tissues. They resemble osseous giant cell tumors morphologically and immunohistochemically. The tumor exhibits strong positive immunoreactivity for cluster of differentiation 68 (CD68 within multinucleated osteoclast-like giant cells and focal staining of mononuclear cells. Case reports describing the cytohistological features of this entity are very few. We report a case of GCT-ST of low malignant potential diagnosed on fine needle aspiration (FNA and confirmed on histological and immunohistochemical studies.

    2015-08-01

    The aim of the study was to determine whether individualized coaching improved surgical technical skill in the operating room to a higher degree than current residency training. Clinical training in the operating room is a valuable opportunity for surgeons to acquire skill and knowledge; however, it often remains underutilized. Coaching has been successfully used in various industries to enhance performance, but its role in surgery has been insufficiently investigated. This randomized controlled trial was conducted at one surgical training program. Trainees undergoing a minimally invasive surgery rotation were randomized to either conventional training (CT) or comprehensive surgical coaching (CSC). CT included ward and operating room duties, and regular departmental teaching sessions. CSC comprised performance analysis, debriefing, feedback, and behavior modeling. Primary outcome measures were technical performance as measured on global and procedure-specific rating scales, and surgical safety parameters, measured by error count. Operative performance was assessed by blinded video analysis of the first and last cases recorded by the participants during their rotation. Twenty residents were randomized and 18 completed the study. At posttraining the CSC group (n = 9) scored significantly higher on a procedure-specific skill scale compared with the CT group (n = 9) [median, 3.90 (interquartile range, 3.68-4.30) vs 3.60 (2.98-3.70), P = 0.017], and made fewer technical errors [10 (7-13) vs 18 (13-21), P = 0.003]. Significant within-group improvements for all skill metrics were only noted in the CSC group. Comprehensive surgical coaching enhances surgical training and results in skill acquisition superior to conventional training.

    Aspiration of oropharyngeal material, with its high concentration of anaerobic bacteria, has been implicated in the pathogenesis of both ventilator-associated pneumonia (VAP) and aspiration pneumonitis (AP). Consequently, patients with these disorders are usually treated with antimicrobial agents with anaerobic activity. To determine the incidence of anaerobic bacteria in patients with VAP and AP. Prospective, nonrandomized, interventional study. University-affiliated community teaching hospital. We performed sequential blind protected specimen brush (PSB) sampling and mini-BAL in 143 patients with 185 episodes of suspected VAP and 25 patients with AP who required mechanical ventilation. Quantitative aerobic and anaerobic cultures were performed on all specimens. Pneumonia was considered to be present when either > 500 cfu/mL cultured from blind PSB sampling or > 5,000 cfu/mL cultured from mini-BAL were present. Using the predefined criteria, bacterial pneumonia was diagnosed in 63 of 185 suspected VAP episodes (34%) and 12 of 25 patients with AP (48%). At least one dose of an antibiotic was given in the 24 h prior to bacteriologic sampling in 106 suspected VAP episodes (57%) and in 12 patients with AP (48%). More than one pathogen was isolated from 11 VAP and four AP patients. Pseudomonas aeruginosa, Staphylococcus aureus, and enteric Gram-negative organisms were isolated most frequently from patients with VAP. In the patients with AP, enteric Gram-negative organisms were isolated in patients with GI disorders and Streptococcus pneumoniae and Haemophilus influenzae predominated in patients with "community-acquired" aspiration. Only one anaerobic organism was isolated from the entire group of patients; Veillonella paravula was isolated from a blind PSB specimen in a patient with suspected aspiration pneumonia. Despite painstaking effort, we were able to isolate only one anaerobic organism (nonpathogenic) from this group of patients. The spectrum of aerobes in

    As surgery needs have increased, the traditional surgical team has expanded to include personnel from radiology and perfusion services. A new surgical team member, the intraoperative monitoring technician, is needed to perform intraoperative monitoring during procedures that carry a higher risk of central and peripheral nerve injury. Including the intraoperative monitoring technician on the surgical team can create challenges, including surgical delays and anesthesia care considerations. When the surgical team members, including the surgeon, anesthesia care provider, and circulating nurse, understand and facilitate this new staff member's responsibilities, the technician is able to perform monitoring functions that promote the smooth flow of the surgical procedure and positive patient outcomes.

    Full Text Available Achieving a level of technical skill and confidence in surgical operations is the main goal of plastic surgical training. Operating rooms were accepted as the practical teaching venues of the traditional apprenticeship model. However, increased patient population, time, and ethical and legal considerations made preoperation room practical work a must for plastic surgical training. There are several plastic surgical teaching models and simulators which are very useful in preoperation room practical training and the evaluation of plastic surgery residents. The full thickness skin with its vascular network excised in abdominoplasty procedures is an easily obtainable real human tissue which could be used as a training model in plastic surgery.

    Inadvertent hypothermia is not uncommon in the immediate postoperative period and it is associated with impairment and abnormalities in various organs and systems that can lead to adverse outcomes. The aim of this study was to estimate the prevalence, the predictive factors and outcome of core hypothermia on admission to a surgical ICU. All consecutive 185 adult patients who underwent scheduled or emergency noncardiac surgery admitted to a surgical ICU between April and July 2004 were admitted to the study. Tympanic membrane core temperature (Tc) was measured before surgery, on arrival at ICU and every two hours until 6 hours after admission. The following variables were also recorded: age, sex, body weight and height, ASA physical status, type of surgery, magnitude of surgical procedure, anesthesia technique, amount of intravenous fluids administered during anesthesia, use of temperature monitoring and warming techniques, duration of the anesthesia, ICU length of stay, hospital length of stay and SAPS II score. Patients were classified as either hypothermic (Tc 35 degrees C). Univariate analysis and multiple regression binary logistic with an odds ratio (OR) and its 95% Confidence Interval (95%CI) were used to compare the two groups of patients and assess the relationship between each clinical predictor and hypothermia. Outcome measured as ICU length of stay and mortality was also assessed. Prevalence of hypothermia on ICU admission was 57.8%. In univariate analysis temperature monitoring, use of warming techniques and higher previous body temperature were significant protective factors against core hypothermia. In this analysis independent predictors of hypothermia on admission to ICU were: magnitude of surgery, use of general anesthesia or combined epidural and general anesthesia, total intravenous crystalloids administrated and total packed erythrocytes administrated, anesthesia longer than 3 hours and SAPS II scores.

    Full Text Available With disease progression, avascular necrosis (AVN of the femoral head may lead to a collapse of the articular surface. The exact pathophysiology of AVN remains unclear, although several conditions are known that can result in spontaneous cell death, leading to a reduction of trabecular bone and the development of AVN. Hip AVN treatment is stage-dependent in which two main stages of the disease can be distinguished: pre-collapse (ARCO 0-II and post-collapse stage (ARCO III-IV, crescent sign. In the pre-collapse phase, core decompression (CD, with or without the addition of bone marrow (e.g. bone marrow aspirate concentrate, BMAC or bone graft, is a common treatment alternative. In the postcollapse phase, THA (total hip arthroplasty must be performed in most of the patients. In addition to surgical treatment, the intravenous application of Iloprost has been shown to have a curative potential and analgesic effect. From October 2009 to October 2014, 49 patients with AVN (stages I-III were treated with core decompression at our institution. All patients were divided into group A (CD + BMAC and group B (CD alone. Of these patients, 20 were included in a matched pair analysis. The patients were matched to age, gender, ARCO-stage, Kerboul combined necrotic angle, the cause of AVN, and whether Iloprost-therapy was performed. The Merle d’Aubigné Score and the Kerboul combined necrotic angle in a-p and lateral radiographs were evaluated pre- and postoperatively. The primary endpoint was a total hip arthroplasty. In group A, two patients needed THA while in group B four patients were treated with THA. In group A, the Merle d’Aubigné Score improved from 13.5 (pre-operatively to 15.3 (postoperatively. In group B there was no difference between the pre- (14.3 and postoperative (14.1 assessment. The mean of the Kerboul angle showed no difference in both groups compared pre- to postoperatively (group A: pre-op 212°, postop 220°, group B: pre-op 213

    Full Text Available The introduction of robotic surgery within the operating rooms has significantly improved the quality of many surgical procedures. Recently, the research on medical robotic systems focused on increasing the level of autonomy in order to give them the possibility to carry out simple surgical actions autonomously. This paper reports on the development of technologies for introducing automation within the surgical workflow. The results have been obtained during the ongoing FP7 European funded project Intelligent Surgical Robotics (I-SUR. The main goal of the project is to demonstrate that autonomous robotic surgical systems can carry out simple surgical tasks effectively and without major intervention by surgeons. To fulfil this goal, we have developed innovative solutions (both in terms of technologies and algorithms for the following aspects: fabrication of soft organ models starting from CT images, surgical planning and execution of movement of robot arms in contact with a deformable environment, designing a surgical interface minimizing the cognitive load of the surgeon supervising the actions, intra-operative sensing and reasoning to detect normal transitions and unexpected events. All these technologies have been integrated using a component-based software architecture to control a novel robot designed to perform the surgical actions under study. In this work we provide an overview of our system and report on preliminary results of the automatic execution of needle insertion for the cryoablation of kidney tumours.

    To assess ultrasonographically (US) guided needle aspiration of breast abscesses as an alternative to surgical incision and drainage. In our prospective study, 30 patients with 31 breast abscesses (one patient had bilateral breast abscess) underwent percutaneous breast abscess drainage under US guidance with local anaesthesia and oral antibiotics between 1 January 2004 and 31 March 2005. These patients consisted of 16 (53.3%) non-lactating and 14 (46.7%) lactating women, with ages ranging from 18 to 68 years (median, 28 years). The racial distribution comprised 26 (86.7%) Malays, three (10%) Chinese and one (3.3%) Indian. All patients had the chief complaint of breast swelling and 25 (83.3%) had breast pain. Clinically, 28 (93.3%) were found to have a palpable mass. Nine (30%) lesions were in the upper outer quadrant of the left breast. US diameters ranged from 1 to 15 cm (median, 4 cm). The pus volumes varied from 1 to 200 mL (median, 14 mL). Fifteen (50%) patients required only a single aspiration, 10 required multiple aspirations and five required incision and drainage. Those patients in whom needle aspiration failed had multiloculated lesions irrespective of abscess volume and size. Needle aspiration with ultrasound guidance is an effective treatment for breast abscess irrespective of abscess volume and size.

    Malignant nodular hidradenoma (MNH) is a malignant adnexal tumor of the eccrine sweat glands. The histology is similar to that of benign nodular hidradenoma, but MNH shows an infiltrative and invasive pattern, necrosis and angiolymphatic invasion. A 60-year-old woman, diagnosed with rectal adenocarcinoma 6 months before, underwent fine needle aspiration (FNA) of a nodule on the scalp. The aspirate smears showed (1) necrotic debris; (2) cohesive cell clusters and tissue fragments; (3) tubular formations; (4) globoid or cylindrical clear cells; (5) cells showing dense cytoplasm and a basaloid appearance; (6) cell sheets with anaplasia and squamous differentiation; and (7) multinucleated giant cells. The histology showed a lobulated pattern with necrosis and cyst formation. The clear cells that were seen on cytology occupied the periphery of the lobules, whereas the anaplastic cells were located in the central portion. Squamous differentiation and tubular formations were observed. Rapid, accurate diagnosis of these tumors is important, particularly when they develop at sites where a metastatic process must be ruled out. Cytology of FNA material provides this capability.

    Simple liver cysts are congenital with a prevalence of 2.5%-4.25%. Imaging, whether by US, CT or MRI,is accurate in distinguishing simple cysts from other etiologies, including parasitic, neoplastic, duct-related,and traumatic cysts. Symptomatic simple liver cysts are rare, and the true frequency of symptoms is not known.Symptomatic simple liver cysts are predominantly large (> 4 cm), right-sided, and more common in women and older patients. The vast majority of simple hepatic cysts require no treatment or follow-up, though large cysts (> 4 cm) may be followed initially with serial imaging to ensure stability. Attribution of symptoms to a large simple cyst should be undertaken with caution, after alternative diagnoses have been excluded. Aspiration may be performed to test whether symptoms are due to the cyst; however, cyst recurrence should be expected.Limited experience with both laparoscopic deroofing and aspiration, followed by instillation of a sclerosing agent has demonstrated promising results for the treatment of symptomatic cysts. Here, we describe a patient with a large, symptomatic, simple liver cyst who experienced complete resolution of symptoms following cyst drainage and alcohol ablation, and we present a comprehensive review of the literature.

    Oropharyngeal aspiration (OPA) can lead to recurrent respiratory illnesses and chronic lung disease in children. Current clinical feeding evaluations performed by speech pathologists have poor reliability in detecting OPA when compared to radiological procedures such as the modified barium swallow (MBS). Improved ability to diagnose OPA accurately via clinical evaluation potentially reduces reliance on expensive, less readily available radiological procedures. Our study investigates the utility of adding cervical auscultation (CA), a technique of listening to swallowing sounds, in improving the diagnostic accuracy of a clinical evaluation for the detection of OPA. We plan an open, unblinded, randomised controlled trial at a paediatric tertiary teaching hospital. Two hundred and sixteen children fulfilling the inclusion criteria will be randomised to one of the two clinical assessment techniques for the clinical detection of OPA: (1) clinical feeding evaluation only (CFE) group or (2) clinical feeding evaluation with cervical auscultation (CFE + CA) group. All children will then undergo an MBS to determine radiologically assessed OPA. The primary outcome is the presence or absence of OPA, as determined on MBS using the Penetration-Aspiration Scale. Our main objective is to determine the sensitivity, specificity, negative and positive predictive values of 'CFE + CA' versus 'CFE' only compared to MBS-identified OPA. Early detection and appropriate management of OPA is important to prevent chronic pulmonary disease and poor growth in children. As the reliability of CFE to detect OPA is low, a technique that can improve the diagnostic accuracy of the CFE will help minimise consequences to the paediatric respiratory system. Cervical auscultation is a technique that has previously been documented as a clinical adjunct to the CFE; however, no published RCTs addressing the reliability of this technique in children exist. Our study will be the first to establish the utility

    Full Text Available Introduction: Intact surgical gloves are a barrier to microorganisms migration between surgical team members and the patient. The surgical gloves are changed at various junctures but the effects of changing gloves during surgical procedures on various surgical parameters or clinical outcomes are not established. Aim: To determine rationale of glove change during orthopaedic procedures, differences amongst surgical parameters with and without changing the surgical gloves and whether frequent glove change affected surgical parameters or clinical outcomes. Materials and Methods: A prospective multicenter study conducted at three centers from January 2014 to January 2016. A 250 patients were divided into 2 groups (n=125 each in Group 1, surgical team operated with regular changing of gloves. In Group 2, only 1 set of double gloves were worn throughout the procedure. Surgical parameters or clinical outcomes were assessed for both the groups. Statistical analyses included the median, mode, range, Interquartile Range (IQR and sample standard deviation (s and independent-samples t-test. Bacterial counts were expressed as median with (IQR. Results: Surgical Timing Difference was 10 (S.D.- 4.2 minutes more in Group-1 (<0.05, Surgical Cost was higher in Group-1 by Rs.150-450 (<0.05. Outer glove micro-perforation rate was 5.85% and 8.15% in group-1 and 2 respectively with no inner glove perforation or Surgical Site Infections. Outer glove micro perforations were proportional to duration of surgery; operations lasting 120-210 and 61-120 minutes had 66.6% and 37.2% micro perforation rates respectively (p<0.05. Conclusion: Under standard operating conditions, procedures performed without glove change are shorter and cost effective than procedures performed with regular glove change with similar surgical and functional results. Judicious use of surgical gloves is a patient and environment friendly option, thereby reducing the hospital’s biomedical waste load.

    To assess the incidence of aspiration pneumonia in infants with cleft palate and to compare the incidence between complete and incomplete types of cleft palate. A review of medical records revealed 100 infants who had undergone initial surgery to repair cleft palate in our hospital during a recent three-year period. Aspiration pneumonia was defined as the coexistence of pneumonia at chest radiography with a history of frequent choking during feeding. The anatomic distribution of aspiration pneumonia was analyzed, and the incidences of aspiration pneumonia in infants with complete and incomplete cleft palate were compared. Among 100 children, aspiration pneumonia was found in 35 (35%). Those with complete and incomplete cleft palate showed similar incidences of the condition (27 of 70 [39%] vs 8 of 30 [27%], p=0.36). Pneumonia was most commonly seen in the left lower lobe (11 of 35), followed by the right upper and lower lobes. Aspiration pneumonia is frequently associated with infants with cleft palate. There is no statistical difference in the incidence of aspiration pneumonia between the complete and the incomplete cleft palate group.

    There are some concerns that medical student interest in surgery is suffering. The aims of this project were to investigate the proportion of medical students interested in surgery from years 1 to 4, explore influential attitudinal and demographic factors, and establish baseline data to study the future effects of the Surgical Interest Association. Students were surveyed through an audience response system in year orientation sessions. For a majority of the analyses, respondents were dichotomized based on expressing an interest in surgery or not. There were no significant differences in the interest students had for a surgical career between medical student year levels in a cross-sectional analysis. However, available longitudinal data demonstrated a significant decrease in surgical interest from first years in 2012 to second years in 2013. Lifestyle, working hours and training length concerns had minimal effects as career influences on students interested in surgery, whereas academic interest and career opportunities were motivating factors in choosing this career. The results suggested no difference between levels of interest from first to final year students in surgery as a career, though only 22% of final year students were interested in surgery. This study also suggested that promoting the academic and scientific side of surgery, along with career opportunities available, may be an important avenue to encourage students into surgery. Future research will investigate the changing interests of students in surgery longitudinally throughout the medical school and to analyse the effects of the Surgical Interest Association. © 2014 Royal Australasian College of Surgeons.

    The purpose of this study was to evaluate the mechanism of luminal gain with a novel atheroablation system (Pathway PV) for the treatment of peripheral artery disease using intravascular ultrasound (IVUS). The atherectomy system is a rotational atherectomy device, which employs expandable rotating blades with ports that allow flushing and aspiration of the plaque material or thrombus. In this first-in-man clinical study, IVUS analysis was available in 6 patients with lower limb ischemia treated with this device. The treatment results were assessed using IVUS at pre and post atherectomy. Lumen beyond burr size (LBB) was defined as lumen gain divided by the estimated burr area determined by the burr-size. IVUS analysis was available in six patients (superficial femoral artery n=3, popliteal artery n=2, posterior tibial artery n=1). Atheroablation achieved a significant increase in lumen area (LA) (preintervention 3.9+/-0.4, postatheroablation 8.0+/-1.7 mm(2), Patherectomy device achieved significant luminal gain by debulking in the absence of vessel stretching. The LA was greater than burr-sized lumen expectancy at cross-sections along the treated segments, suggesting a complimentary role of aspiration in luminal gain in atherosclerotic peripheral artery lesions.

  19. The accuracy of fine-needle aspiration cytology for diagnosis of parotid gland masses: a clinicopathological study of 114 patients

    Full Text Available ABSTRACT Objective Fine-needle aspiration cytology is a valuable method for preoperative assessment of head and neck tumors. However, its accuracy in detection of salivary gland masses is controversial compared with other methods. The aim of this work was to evaluate the effectiveness and accuracy of fine-needle aspiration cytology (FNAC in the diagnosis of parotid gland masses. Material and Methods Over a 10-year period, 126 parotid gland masses were resected. Retrospective chart reviews of 114 patients were performed. The results of FNAC and final histological diagnosis were compared and the accuracy of FNAC was determined. Results Final histological evaluation revealed 11 malignant tumors and 103 benign lesions. Pleomorphic adenoma was the most common neoplasm (63%, followed by Warthin’s tumor (17.5%. The sensitivity of FNAC in detecting malignant tumors was 73% and the specificity was 97%. Positive predictive value (PPV was 73% and negative predictive value (NPV was 97%. The overall accuracy of FNAC in detecting parotid masses was 95%. False-negative diagnosis was found in mucoepidermoid carcinoma, acinic cell carcinoma, and epithelial-myoepithelial carcinoma whereas there was false-positive diagnosis in cases of pleomorphic adenoma and normal parotid gland tissue. Conclusion FNAC is a reliable minimally invasive diagnostic method with a high sensitivity in diagnosis of lesions in parotid glands. The sensitivity of detection of malignant tumors in parotid glands was low due to the biopsy technique used, and depended on tumor location. Postoperative complications decreased after superficial parotidectomy.

    Acquisition of skills early in surgical training represents a significant challenge at present because of training time constraints. The aim of this study was to investigate if an intensive surgical boot camp was effective in transferring skills at the beginning of a surgical training program. New core surgical trainees (n = 58) took part in a 5-day boot camp. There were pretest and posttest assessments of knowledge, technical skills, and confidence levels. The boot camp used simulation and senior surgical faculty to teach a defined range of technical and nontechnical skills. The scores for knowledge (53.8% vs 68.4%, P technical skills (35.9% to 60.6% vs 50.6% to 78.2%, P Skills improvements were still present a year later. The 5-day surgical boot camp proved to be an effective way to rapidly acquire surgical knowledge and skills while increasing the confidence levels of trainees. Copyright © 2015 Elsevier Inc.

    To examine the influence of personal and situational factors on direct-care nurses' interests in pursuing nursing management roles. Nursing managers are ageing and nurses do not appear to be interested in nursing management roles, raising concerns about a nursing leadership shortage in the next decade. Little research has focused on factors influencing nurses' career aspirations to nursing management roles. A national survey of nurses from nine Canadian provinces was conducted (n = 1241). Multiple regression was used to test a model of personal and situational predictors of nurses' career aspirations to management roles. Twenty-four per cent of nurses expressed interest in pursuing nursing management roles. Personal and situational factors explained 60.2% of nurses' aspirations to management roles. Age, educational preparation, feasibility of further education, leadership self-efficacy, career motivation, and opportunity to motivate others were the strongest predictors of aspirations for management roles. Personal factors were more strongly associated with career aspirations than situational factors. There is a steady decline in interest in management roles with increasing age. Nursing leadership training to develop leadership self-efficacy (particularly for younger nurses) and organizational support for pursuing advanced education may encourage nurses to pursue nursing management roles. © 2012 Blackwell Publishing Ltd.

The BRAFV600E mutation is the most promising marker for thyroid FNA. This meta-analysis was conducted to investigate the diagnostic value of BRAFV600E analysis in thyroid FNA, especially the indeterminate cases. Systematic searches were performed in PubMed, Web of Science, Scopus, Ovid, Elsevier, and the Cochrane Library databases for relevant studies prior to June 2015, and a total of 88 studies were ultimately included in this meta-analysis. Compared with FNA cytology, the synergism of BRAFV600E testing increased the diagnostic sensitivity from 81.4% to 87.4% and decreased the false-negative rate from 8% to 5.2%. In the indeterminate group, the mutation rate of BRAFV600E was 23% and varied in different subcategories (43.2% in suspicious for malignant cells [SMC], 13.77% in atypia of undetermined significance/follicular lesion of undetermined significance [AUS/FLUS], and 4.43% in follicular neoplasm/suspicious for follicular neoplasm [FN/SFN]. The sensitivity of BRAFV600E analysis was higher in SMC than that in AUS/FLUS and FN/SFN cases (59.4% vs 40.1% vs 19.5% respectively, while specificity was opposite (86.1% vs 99.5% vs 99.7% respectively. The areas under the summary receiver-operating characteristic curve also confirmed the diagnostic value of BRAFV600E testing in SMC and AUS/FLUS rather than FN/SFN cases. Therefore, BRAFV600E analysis can improve the diagnostic accuracy of thyroid FNA, especially indeterminate cases classified as SMC, and select malignancy

    2012-05-01

    To identify the reasons why interns would not choose a surgical career. This qualitative study used semi-structured telephone interviews to explore the future career choices of 41 junior doctors (14 men, 27 women). Doctors were asked to identify specialties they would not take up, and state why this was the case. Thirty (73.2%) of the 41 interns nominated surgery as a specialty they would not choose. Themes relating to reasons for not wanting to pursue a surgical career included the lifestyle associated with surgery (66.7%), the culture within the surgical work environment (53.3%), the lack of interest in performing surgical work (36.7%), and the training requirements associated with surgery (33.3%). Both sexes had similar reasons for not wanting to choose a surgical career; but additionally, women referred to the male domination of surgery, and the difficulty and inflexibility of the training program as deterrents. Efforts are needed to promote interest in surgery as a career especially for women, to improve the surgical work environment so that medical students and junior doctors have exposure to positive role models and surgical placements, and to provide a more flexible approach to surgical training.

    2015-08-01

    An estimated 550 to 650 surgical fires occur annually in the United States. Surgical fires may have severe consequences, including burns, disfigurement, long-term medical care, or death. This article introduces a potential certification program for the prevention of surgical fires. A pilot study was conducted with a convenience sample of 10 anesthesia providers who participated in the education module. The overall objective was to educate surgical team members and to prepare them to become certified in surgical fire prevention. On completion of the education module, participants completed the 50-question certification examination. The mean pretest score was 66%; none of the participants had enough correct responses (85%) to be considered competent in surgical fire prevention. The mean post- test score was 92.80%, with all participants answering at least 85% of questions correct. A paired-samples t test showed a statistically significant increase in knowledge: t (df = 9) = 11.40; P = .001. Results of the pilot study indicate that this course can remediate gaps in knowledge of surgical fire prevention for providers. Their poor performance on the pretest suggests that many providers may not receive sufficient instruction in surgical fire prevention.

  14. A Novel Surgical Template Design in Staged Dental Implant Rehabilitations

    Directory of Open Access Journals (Sweden)

    Michael Patras

    2012-05-01

    Full Text Available Background: The philosophy of a gradual transition to an implant retained prosthesis in cases of full-mouth or extensive rehabilitation usually involves a staged treatment concept. In this therapeutic approach, the placement of implants may sometimes be divided into phases. During a subsequent surgical phase of treatment, the pre-existing implants can serve as anchors for the surgical template. Those modified surgical templates help in the precise transferring of restorative information into the surgical field and guide the optimal three-dimensional implant positioning. Methods: This article highlights the rationale of implant-retained surgical templates and illustrates them through the presentation of two clinical cases. The templates are duplicates of the provisional restorations and are secured to the existing implants through the utilization of implant mounts. Results: This template design in such staged procedures provided stability in the surgical field and enhanced the accuracy in implant positioning based upon the planned restoration, thus ensuring predictable treatment outcomes.Conclusions: Successful rehabilitation lies in the correct sequence of surgical and prosthetic procedures. Whenever a staged approach of implant placement is planned, the clinician can effectively use the initially placed implants as anchors for the surgical template during the second phase of implant surgery.

    Fine-needle aspiration (FNA) with cytological evaluation reliably diagnoses primary and secondary thyroid neoplasms. However, identifying the primary origin of a metastatic process involving the thyroid gland is challenging. In particular, metastasis of colon cancer to the thyroid gland is very rare. In this case report, a right lobe solid thyroid nodule in a 66-year-old male was aspirated. FNA cytology showed necrosis and atypical tall columnar cells; since, the patient at age 60 had undergone surgery for a sigmoid-rectal cancer metastasizing to the liver and subsequently to the lung, a suspicion of metastasis from colon cancer was raised. This was corroborated by cell-block immunocytochemistry showing a cytokeratin (CK) 7 negative/CK20-positive staining pattern; thyreoglobulin and TTF-1 were both negative. Since KRAS codon 12/13 mutations frequently occur in colon cancer, whereas they are extremely uncommon in primary thyroid tumors, DNA was extracted from the aspirated cells, and KRAS mutational analysis was carried out. The codon 12 G12D mutation was found; the same mutation was evident in the primary cancer of the colon and in its liver and lung metastasis. Thus, a combined cytological, immunocytochemical and molecular approach unquestionably correlated metastatic adenocarcinoma cells aspirated from the thyroid to a colo-rectal origin. © 2010 Wiley-Liss, Inc.

  17. Fine needle aspiration cytology of cervicofacial actinomycosis

    Full Text Available Actinomycosis is a chronic infection caused by Actinomyces israelii, usually seen in immunocompromised patients or in the background of tissue injury. Cervicofacial actinomycosis presenting as a fixed jaw swelling in an elderly individual can mimic malignancy and pose a diagnostic dilemma. We report here a case of cervicofacial actinomycosis diagnosed by fine needle aspiration, along with a review of the relevant literature. A 60 year-old man presented with a gradually increasing 6 x 5 cm swelling in the left side of his jaw. The swelling was fixed, without any apparent sinus or abscess. Fine needle aspiration was diagnostic as it revealed colonies of actinomyces surrounded by polymorphs and chronic inflammatory cells. The histopathological study of the excised specimen confirmed the cytological findings. Fine needle aspiration is an effective tool in the diagnosis of actinomycosis although its documentation is rare. Difficulties in the management can be avoided by early diagnosis using the fine needle aspiration technique.

    Magnetic resonance imaging (MRI) of 18 knees of patients with arthritis was performed before and immediately after arthrocentesis. Pre- and post-aspiration volumes were calculated by adding the outlined areas of synovium/effusion from a continuous series of gadolinium-DTPA-enhanced 5 mm transversal...... T1-weighted MR-images. The difference between MRI-determined and syringe-determined volumes of aspirated joint fluid was 0-7 ml, median 2 ml, corresponding to 0-18%, median 7%, of the pre-aspiration effusion volume. Synovial membrane volumes, determined before and after arthrocentesis varied 0-10 ml......, median 3 ml (0-17%, median 7%). No significant systematic misinterpretation of the borderline between joint fluid and synovium was found. We conclude that effusion volumes and in all probability also synovial membrane volumes, can be determined by MRI with a maximal analytical error of approximately 20...

    2011-12-01

    The craniomaxillofacial defect and deformity always leads to serious dysfunction in mastication and facial contour damage, significantly reducing patients' quality of life. However, surgical reconstruction of a craniomaxillofacial hard tissue defect or deformity is extremely complex and often does not result in desired facial morphology. Improving the result for patients with craniomaxillofacial defect and deformity remains a challenge for surgeons. Using digital technology for surgical diagnosis and treatment may help solve this problem. Computer-assisted surgical technology and surgical navigation technology are included in the accurate digital diagnosis and treatment system we propose. These technologies will increase the accuracy of the design of the operation plan. In addition, the intraoperative real-time navigating location system controlling the robotic arm or advanced intelligent robot will provide accurate, individualized surgical treatment for patients. Here we propose the hypothesis that a digital surgical diagnosis and treatment technology may provide a new approach for precise surgical reconstruction of complicated craniomaxillofacial defect and deformity. Our hypothesis involves modern digital surgery, a three-dimensional navigation surgery system and modern digital imaging technology, and our key aim is to establish a technological platform for customized digital surgical design and surgical navigation for craniomaxillofacial defect and deformity. If the hypothesis is proven practical, this novel therapeutic approach could improve the result of surgical reconstruction for craniomaxillofacial defect and deformity for many patients.

    2017-03-01

    Surgical emphysema is a rare complication of dental extractions, often associated with the use of high-speed air rotors. This report describes a case of extensive surgical emphysema following a simple surgical extraction of a LL6 under local anaesthetic. There was no use of air-driven handpieces during the procedure. The patient developed extensive surgical emphysema bi-laterally in both cervical neck and facial planes. After prophylactic antibiotics with careful monitoring in a secondary care setting, the patient made a full unremarkable recovery. Clinical relevance: Simple extraction of teeth is a procedure carried out daily by most general dental practitioners. However, the risk of surgical emphysema without the use of high-speed air rotors or instruments using pressurized air/water is not well known or documented.

    Perc & Wang demonstrated that aspiring to be the fittest under conditions of pairwise strategy updating enhances network reciprocity in structured populations playing 2×2 Prisoner's Dilemma games (Z. Wang, M. Perc, Aspiring to the fittest and promoted of cooperation in the Prisoner's Dilemma game, Physical Review E 82 (2010) 021115; M. Perc, Z. Wang, Heterogeneous aspiration promotes cooperation in the Prisoner's Dilemma game, PLOS one 5 (12) (2010) e15117). Through numerical simulations, this paper shows that network reciprocity is even greater if heterogeneous aspirations are imposed. We also suggest why heterogeneous aspiration fosters network reciprocity. It distributes strategy updating speed among agents in a manner that fortifies the initially allocated cooperators' clusters against invasion. This finding prompted us to further enhance the usual heterogeneous aspiration cases for heterogeneous network topologies. We find that a negative correlation between degree and aspiration level does extend cooperation among heterogeneously structured agents.

    Full Text Available Aspiration can cause a diverse spectrum of pulmonary disorders some of which can lead to death but can be difficult to diagnose.The medical records and autopsy findings of 57 consecutive patients in whom aspiration was the immediate cause of death at Mayo Clinic (Rochester, MN, USA over a 9-yr period, from January 1 2004 to December 31 2012 were analyzed.The median age at death was 72 years (range, 13-95 years and included 39 (68% males. The most common symptom before death was dyspnea (63% and chest radiography revealed bilateral infiltrates in the majority (81%. Most common precipitating factors for aspiration were depressed consciousness (46% and dysphagia (44%. Aspiration-related syndromes leading to death were aspiration pneumonia in 26 (46%, aspiration pneumonitis in 25 (44%, and large airway obstruction in 6 patients (11%. Aspiration was clinically unsuspected in 19 (33% patients. Antimicrobial therapy had been empirically administered to most patients (90% with aspiration pneumonia and aspiration pneumonitis.We conclude aspiration-related deaths occur most commonly in the elderly with identifiable risks and presenting bilateral pulmonary infiltrates. One-third of these aspiration-related pulmonary syndromes were clinically unsuspected at the time of death.

    Cough reflex testing has been evaluated as a component of the clinical swallowing assessment as a means of identifying patients at risk of aspiration during swallowing. A previous study by our research group found good sensitivity and specificity of the cough reflex test for identifying patients at risk of aspiration post-stroke, yet its use did not decrease pneumonia rates, contrary to previous reports. The aim of this study was to expand on our earlier work by implementing a clinical management protocol incorporating cough reflex testing within the same healthcare setting and compare patient outcomes to those from the original study and to evaluate clinical outcomes in patients with acute stroke who were managed using the Dysphagia in Stroke Protocol (DiSP). Secondarily, to compare those outcomes to historical data prior to implementation of the DiSP. This clinical audit measured outcomes from 284 patients with acute stroke managed per the DiSP, which guides use of videofluoroscopic swallowing study and patient management based on clinical exam with cough reflex testing. Data from our previous trial were included for comparison of pre- and post-DiSP patient outcomes. Data collection took place between November 2012 and April 2016 at four urban hospitals within New Zealand. Following implementation of the DiSP, the rate of aspiration pneumonia (10%) was substantially lower than the pre-DiSP rate (28%), with no pneumonia readmissions within 3 months. Pneumonia-related mortality was unchanged. By 3 months, 81% of the patients were on a normal diet and 67% had returned home, compared to pre-DiSP outcomes of 55% and 55% respectively. Previous work has suggested that simply implementing cough reflex testing in dysphagia management may not be sufficient to improve patient outcomes. The present study adds to this picture by suggesting that the true variable of influence may be the way in which the results of the test are applied to patient care. There is a strong case

    To compare cumulative dissipated energy (CDE), aspiration fluid used, and aspiration time during phacoemulsification cataract extraction using 2 surgical configurations. Two clinical sites in the United States and 1 in Spain. Prospective randomized clinical case series. For each patient, the first eye having surgery was randomized to the active-fluidics configuration (Centurion Vision System with Active Fluidics, 0.9 mm 45-degree Intrepid Balanced tip, and 0.9 mm Intrepid Ultra infusion sleeve) or the gravity-fluidics configuration (Infiniti Vision System with gravity fluidics, 0.9 mm 45-degree Mini-Flared Kelman tip, and 0.9 mm Ultra infusion sleeve). Second-eye surgery was completed within 14 days after first-eye surgery using the alternate configuration. The CDE, aspiration fluid used, and aspiration time were compared between configurations, and adverse events were summarized. Patient demographics and cataract characteristics were similar between configurations (100 per group). The CDE was significantly lower with the active-fluidics configuration than with the gravity-fluidics configuration (mean ± standard error, 4.32 ± 0.28 percent-seconds) (P < .001). The active-fluidics configuration used significantly less aspiration fluid than the gravity-fluidics configuration (mean 46.56 ± 1.39 mL versus 52.68 ± 1.40 mL) (P < .001) and required significantly shorter aspiration time (mean 151.9 ± 4.1 seconds versus 167.6 ± 4.1 seconds) (P < .001). No serious ocular adverse events related to the study devices or device deficiencies were observed. Significantly less CDE, aspiration fluid used, and aspiration time were observed with the active-fluidics configuration than with the gravity-fluidics configuration, showing improved surgical efficiency. Drs. Solomon and Cionni are consultants to Alcon Research, Ltd., and received compensation for conduct of the study. Dr. Lorente received compensation for clinical work in the study.

    Full Text Available A 66-year-old man was admitted to our institute because of chest pain. He had undergone replacement of the ascending aorta due to aortic dissection 9 years previously. We made a diagnosis of acute coronary syndrome, and coronary artery angiography was performed. Although the right coronary artery was successfully cannulated, a severe bend of the artificial aorta made it very difficult to advance the catheter into the left coronary artery. Ultimately, a DIO thrombus aspiration catheter was used to enter the left coronary artery, and a stent was implanted successfully. The DIO catheter is very useful when the selection of a guiding catheter is complicated, such as in the case of severe vessel tortuosity or a bend of the ascending aorta.

    The authors report the case of a 6-year-old girl, presenting with a 4-month history of wheeze associated with barking cough which frequently became wet requiring antibiotics. Her care was transferred to a paediatrician with specialist interest in paediatric respiratory medicine when she had continued symptoms despite bronchodilators and oral steroids for suspected asthma. Spirometry showed a forced expiratory volume 1 of 79% with no evidence of reversibility. The child was investigated for chronic wet cough. Immunoglobulins, sweat test and chest x-ray were all normal. There was no history suggestive of foreign body aspiration (FBA). Tracheomalacia was considered in view of the nature of the cough. The recurrence of an unusual inspiratory noise prompted referral for bronchoscopy. A small piece of plastic tube was removed from the bronchus intermedius. All symptoms resolved. The importance of clinical assessment to ascertain 'wheeze' when acutely unwell is emphasised. Current literature concerning FBA is reviewed.

  9. Primary splenic angiosarcoma with liver metastasis: A rare neoplasm diagnosed on fine-needle aspiration cytology and cell block immunocytochemistry

    2018-01-01

    Full Text Available Primary splenic angiosarcoma is a rare malignant vascular neoplasm of mesenchymal origin. The tumor is highly aggressive and has a high metastatic potential. It is usually diagnosed on histopathological examination of splenectomy specimen. Only few cases of angiosarcoma diagnosed by fine-needle aspiration (FNA cytology alone have been reported in the literature. The cytologic features of angiosarcoma are heterogeneous, however, diagnosis can be suggested by FNA when vasoformative features are present. A 55-year-old female presented with abdominal pain and hepatosplenomegaly. Computed tomography scan revealed a heterogeneous splenic lesion with liver metastases. FNA from the splenic and liver lesions showed moderately pleomorphic tumor cells closely associated with anastomosing vascular channels. Cell block immunocytochemistry (ICC showed tumor cells positive for CD31, CD34, CD68 as well as for CD99. FNA supplemented by cell block ICC can render a definite diagnosis of primary splenic angiosarcoma with liver metastasis.

    A newborn presented with bilious vomiting secondary to a malrotation and presumed perinatal-onset volvulus. Laparotomy was performed at 20 h of age at which the volvulus was derotated. Nevertheless the small but not the large bowel appeared to be completely ischaemic and non-viable. A second-look laparotomy was performed 24 h later with no significant improvement. In a new approach to the problem, nothing further was done and the child was left alone on parenteral nutrition and naso-gastric aspiration for 11 weeks. Further exploration showed that 40 cm of small bowel had survived intact and restorative surgery was carried out. Parenteral nutrition was discontinued after 9 months and the child, now aged 3.5 years, is thriving.

    A 72-year-old man was referred to our department with an incidentally diagnosed bronchogenic carcinoma of the right upper lobe. Positron emission tomography (PET) combined with computed tomography (PET-CT) revealed an unexpected hot spot in the ventral wall of the infrarenal segment of the inferior vena cava (IVC). Diagnostic biopsy of this lesion was performed under CT guidance with semiautomated 20G fine-needle aspiration (FNA) through a 19G coaxial needle. Cytology revealed few carcinoma cells, which led to the remarkable diagnosis of a distant metastasis to the IVC wall. Both the immediate postinterventional CT control and the further surveillance period of the patient were unremarkable; in particular, no signs of bleeding complications were detected. We conclude that coaxial FNA of an IVC wall lesion is technically feasible and may even help diagnose distant metastasis.

  13. Development of a tool for evaluating multimedia for surgical education.

    2008-09-01

    Educational multimedia has been designed to provide surgical trainees with expert operative information outside of the operating theater. The effectiveness of multimedia (e.g., CD-ROMs) for learning has been a common research topic since the 1990s. To date, however, little discussion has taken place on the mechanisms to evaluate the quality of multimedia-driven teaching. This may be because of a lack of research into the development of appropriate tools for evaluating multimedia, especially for surgical education. This paper reports on a small-scale pilot and exploratory study (n = 12) that developed a tool for surgical multimedia evaluation. The validity of the developed tool was established through adaptation of an existing tool, which was reviewed using experts in surgery, usability, and education. The reliability of the developed tool was tested with surgical trainees who used it to assess a multimedia CD-ROM created for teaching basic surgical skills. The findings contribute to an understanding of surgical trainees' experience of using educational multimedia, in terms of characteristics of the learning material for interface design and content and the process of developing evaluation tools, in terms of inclusion of appropriate assessment criteria. The increasing use of multimedia in medical education necessitates the development of standardized tools for determining the quality of teaching and learning. Little research exists into the development of such tools and so the present work stimulates discussion on how to evaluate surgical training.

    Surgical auditing has been developed in order to benchmark and to facilitate quality improvement. The aim of this review is to determine if auditing combined with systematic feedback of information on process and outcomes of care results in lower costs of surgical care. A systematic search of published literature before 21-08-2013 was conducted in Pubmed, Embase, Web of Science, and Cochrane Library. Articles were selected if they met the inclusion criteria of describing a surgical audit with cost-evaluation. The systematic search resulted in 3608 papers. Six studies were identified as relevant, all showing a positive effect of surgical auditing on quality of healthcare and therefore cost savings was reported. Cost reductions ranging from $16 to $356 per patient were seen in audits evaluating general or vascular procedures. The highest potential cost reduction was described in a colorectal surgical audit (up to $1,986 per patient). All six identified articles in this review describe a reduction in complications and thereby a reduction in costs due to surgical auditing. Surgical auditing may be of greater value when high-risk procedures are evaluated, since prevention of adverse events in these procedures might be of greater clinical and therefore of greater financial impact. This systematic review shows that surgical auditing can function as a quality instrument and therefore as a tool to reduce costs. Since evidence is scarce so far, further studies should be performed to investigate if surgical auditing has positive effects to turn the rising healthcare costs around. In the future, incorporating (actual) cost analyses and patient-related outcome measures would increase the audits' value and provide a complete overview of the value of healthcare.

  15. Fine-needle aspiration and core biopsy in the diagnosis of breast lesions: A comparison and review of the literature

    Directory of Open Access Journals (Sweden)

    Suvradeep Mitra

    2016-01-01

    Full Text Available In recent times, the diagnosis of breast lesions has mostly become dependent on core needle biopsies (CNBs with a gradual reduction in the rate of performing fine-needle aspiration cytology (FNAC. Both the procedures have their pros and cons and outsmart each other taking into account different parameters. Both the methods are found to be fraught with loopholes, taking into account different performance indices, diagnostic accuracy and concordance, patient benefit, and cost-effectiveness. Unlike the popular belief of an absolute superiority of CNB over FNAC, the literature review does not reveal a very distinct demarcation in many aspects. We recommend judicious use of these diagnostic modalities in resource-limited settings and screening programs taking into account parameters such as palpability and availability of an experienced cytopathologist.

    Gynecomastia is a common finding in male population of all ages. The aim of our study was to present our experience and goals in surgical treatment of gynecomastia. Clinical records of patients affected by gynecomastia referred to our Department of Surgery between September 2008 and January 2015 were analyzed. 50 patients were included in this study. Gynecomastia was monolateral in 12 patients (24%) and bilateral in 38 (76%); idiopathic in 41 patients (82%) and secondary in 9 (18%). 39 patients (78%) underwent surgical operation under general anaesthesia, 11 (22%) under local anaesthesia. 3 patients (6%) presented recurrent disease. Webster technique was performed in 28 patients (56%), Davidson technique in 16 patients (32%); in 2 patients (4%) Pitanguy technique was performed and in 4 patients (8%) a mixed surgical technique was performed. Mean surgical time was 80.72±35.14 minutes, median postoperative stay was 1.46±0.88 days. 2 patients (4%) operated using Davidson technique developed a hematoma, 1 patient (2%) operated with the same technique developed hypertrophic scar. Several surgical techniques are described for surgical correction of gynecomastia. If performed by skilled general surgeons surgical treatment of gynecomastia is safe and permits to reach satisfactory aesthetic results.

    Full Text Available Background Guidelines and Class 1 evidence are strong factors that help guide surgeons’ decision-making, but dilemmas exist in selecting the best surgical option, usually without the benefit of guidelines or Class 1 evidence. A few studies have discussed the variability of surgical treatment options that are currently available, but no study has examined surgeons’ views on the influential factors that encourage them to choose one surgical treatment over another. This study examines the influential factors and the thought process that encourage surgeons to make these decisions in such circumstances. Methods Semi-structured face-to-face interviews were conducted with 32 senior consultant surgeons, surgical fellows, and senior surgical residents at the University of Toronto teaching hospitals. An e-mail was sent out for volunteers, and interviews were audio-recorded, transcribed verbatim, and subjected to thematic analysis using open and axial coding. Results Broadly speaking there are five groups of factors affecting surgeons’ decision-making: medical condition, information, institutional, patient, and surgeon factors. When information factors such as guidelines and Class 1 evidence are lacking, the other four groups of factors—medical condition, institutional, patient, and surgeon factors (the last-mentioned likely being the most powerful—play a significant role in guiding surgical decision-making. Conclusions This study is the first qualitative study on surgeons’ perspectives on the influential factors that help them choose one surgical treatment option over another for their patients.

    Full Text Available Pure neuroendoscopic resection of intraventricular lesions through a burr hole is limited by the instrumentation that can be used with a working channel endoscope. We describe a safety and feasibility study of a variable aspiration tissue resector, for the resection of a variety of intraventricular lesions. Our initial experience using the variable aspiration tissue resector involved 16 patients with a variety of intraventricular tumors or cysts. Nine patients (56% presented with obstructive hydrocephalus. Patient ages ranged from 20 to 88 years (mean 44.2. All patients were operated on through a frontal burr hole, using a working channel endoscope. A total of 4 tumors were resected in a gross total fashion and the remaining intraventricular lesions were subtotally resected. Fifteen of 16 patients had relief of their preoperative symptoms. The 9 patients who presented with obstructive hydrocephalus had restoration of cerebrospinal fluid flow though one required a ventriculoperitoneal shunt. Three patients required repeat endoscopic resections. Use of a variable aspiration tissue resector provides the ability to resect a variety of intraventricular lesions in a safe, controlled manner through a working channel endoscope. Larger intraventricular tumors continue to pose a challenge for complete removal of intraventricular lesions.

    Quality of any service is the most important aspect for the manufacturer as well as the consumer. The primary objective of any nation's health system is to provide supreme quality health care services to its patients. The objective of this study was to assess the quality of diagnostic fine needle aspiration cytology service in a tertiary care hospital. As Patient's perspectives provide valuable information on quality of process, therefore, patient's perception in terms of satisfaction with the service was measured. In this cross sectional analytical study, 291 patients undergoing fine needle aspiration cytology in Mayo Hospital were selected by systematic sampling technique. Information regarding satisfaction of patients with four dimensions of service quality process, namely "procedure, sterilization, conduct and competency of doctor" was collected through interview on questionnaire. The questionnaire was developed on SERVQUAL model, a measurement tool, for quality assessment of services provided to patients. All items were assessed on 2- point likert scale (0=dissatisfied, 1=satisfied). Frequencies and percentages of satisfied and dissatisfied patients were recorded for each item and all items in each dimension were scored. If the percentage of sum of all item scores of a dimension was ≥60, the dimension was 'good quality'. Whereas quality' dimension. Data was analysed using epi-info-3.5.1.

    The longitudinal relationship between binge drinking and academic engagement, performance, and future aspirations and expectations was examined among a cohort of secondary school students. In separate multinomial generalized estimating equations models, linked data from Year 1 (Y1: 2012-2013), Year 2 (Y2: 2013-2014), and Year 3 (Y3: 2014-2015) of the COMPASS study (N = 27 112) were used to test the relative likelihood of responses to seven academic indices when binge drinking was initiated in varying frequencies, adjusting for gender, grade, race/ethnicity, tobacco use, and the individual mean of the predictor and all time-varying covariates. Among students who had never engaged in binge drinking at baseline, those who reported regular binge drinking at follow-up were relatively less likely to complete their homework, attend class, and value and achieve high grades, with more frequent binge drinking at follow-up generally resulting in larger relative risk ratios. Interestingly, shifting from "never" to "rare/sporadic" binge drinking one to two years later resulted in an increased relative risk of wanting to pursue all levels of postsecondary education. Beginning binge drinking on a "monthly" basis also increased the likelihood of college/ trade or bachelor degree ambitions, relative to high school, but not graduate/professional pathways; while degree aspirations were not associated with initiating weekly binge drinking. Results suggest students who initiate binge drinking have poor school performance and engagement, which may interfere with achieving their future academic goals. This study reinforces the reasons substance use prevention should be considered an academic priority, as such efforts may also prove beneficial for educational achievement.

    The landscape of surgical training is changing. The anticipated increase in the numbers of surgical trainees and the shift to competency-based surgical training places pressures on an already stretched health service. With these pressures in mind, we explored trainers' and trainees' experiences of surgical training in a less traditional rotation, an outer metropolitan hospital. We considered practice-based learning theories to make meaning of surgical training in this setting, in particular Actor-network theory. We adopted a qualitative approach and purposively sampled surgical trainers and trainees to participate in individual interviews and focus groups respectively. Transcripts were made and thematically analysed. Institutional human research ethics approval was obtained. Four surgical trainers and fourteen trainees participated. Almost without exception, participants' report training needs to be well met. Emergent inter-related themes were: learning as social activity; learning and programmatic factors; learning and physical infrastructure; and, learning and organizational structure. This outer metropolitan hospital is suited to the provision of surgical training with the current rotational system for trainees. The setting offers experiences that enable consolidation of learning providing a rich and varied overall surgical training program. Although relational elements of learning were paramount they occurred within a complex environment. Actor-network theory was used to give meaning to emergent themes acknowledging that actors (both people and objects) and their interactions combine to influence training quality, shifting the focus of responsibility for learning away from individuals to the complex interactions in which they work and learn.

    2017-07-21

    A Morel-Lavallee lesion (MLL) is a relatively rare condition that is caused by a traumatic shearing force. This force leads to a closed degloving injury of the subcutaneous tissue and fascia that creates a potential space that can fill with lymph, blood, and necrotic fat. The MLLs are traditionally seen after high impact trauma and typically located at the greater trochanter and pelvis, although recent reports have found them to be located at the knee, thigh, and lower leg. The MLLs typically present as swelling at the site of injury, which can be difficult to differentiate from several other diagnoses. This case report discusses an MLL in the lower extremity that occurred during a rugby game. A lack of familiarity with MLLs often leads to delayed diagnosis and treatment. The diagnosis was eventually made with an magnetic resonance imaging, and the lesion was successfully treated with ultrasound-guided aspiration and compression. The athlete was able to return to play without recurrence of the lesion.

    Breast cancers with Her-2 neu gene amplification are recognized as important markers for aggressive disease and targets which respond to therapy with trastuzumab. Her-2 neu testing on histological sections is routinely performed to select patients who may benefit from anti- Her-2 neu therapy. Few reports are available which document Her-2 neu status on fine needle aspirates (FNA). This pilot study is to document expression of Her-2 neu (Cerb-B2) on cytospin smears from FNA of patients with breast carcinoma. Twenty samples of FNA already collected for diagnostic purposes from patients with primary breast carcinoma were studied for demonstration of Her-2 neu expression by immunohistochemistry (IHC), Fluorescent in-situ hybridization (FISH) and chromogenic in-situ hybridization (CISH) on cytospin smears from FNA. Their expression was compared with tissue sections where possible. Good correlation was observed between Her-2 neu protein expression and gene amplification in cytospin smears. Three of five (60%) breast carcinomas cases with 2+ and 3+ staining on IHC showed gene amplification by FISH and CISH. Three of 7 (43%) and 5 of 7 (71%) cases negative/1+ staining on IHC did not show gene amplification by FISH and CISH respectively. Tissue sections from 10 cases with 2+ and 3+ staining for Her2neu by IHC showed gene amplification in 8 cases. Demonstration of Her-2 neu by IHC, FISH or CISH in FNA is possible and may play a role in the management of patients with advanced breast cancer or those cases where surgical resection is not advisable.

    Muscle rupture is rarely treated surgically. Few reports of good outcomes after muscular suture have been published. Usually, muscular lesions or partial ruptures heal with few side effects or result in total recovery. We report a case of an athlete who was treated surgically to repair a total muscular rupture in the pectoralis major muscle. After 6 months, the athlete returned to competitive practice. After a 2-year follow-up, the athlete still competes in skateboard championships. PMID:25716033

    Near infrared (NIR) fluorescence imaging technique can provide precise and real-time information about tumor location during a cancer resection surgery. However, many intraoperative fluorescence imaging systems are based on wearable devices or stand-alone displays, leading to distraction of the surgeons and suboptimal outcome. To overcome these limitations, we design a projective fluorescence imaging system for surgical navigation. The system consists of a LED excitation light source, a monochromatic CCD camera, a host computer, a mini projector and a CMOS camera. A software program is written by C++ to call OpenCV functions for calibrating and correcting fluorescence images captured by the CCD camera upon excitation illumination of the LED source. The images are projected back to the surgical field by the mini projector. Imaging performance of this projective navigation system is characterized in a tumor simulating phantom. Image-guided surgical resection is demonstrated in an ex-vivo chicken tissue model. In all the experiments, the projected images by the projector match well with the locations of fluorescence emission. Our experimental results indicate that the proposed projective navigation system can be a powerful tool for pre-operative surgical planning, intraoperative surgical guidance, and postoperative assessment of surgical outcome. We have integrated the optoelectronic elements into a compact and miniaturized system in preparation for further clinical validation.

    Advanced age is a strong predictor of high perioperative mortality in surgical patients and patients aged 75 years and older have an elevated surgical risk, much higher than that of younger patients. Progressive advances in surgical techniques now make it possible to treat high-risk surgical patients with minimally invasive procedures. Endovascular techniques have revolutionized the treatment of several vascular diseases, in particular carotid stenosis, aortic pathologies, and severely incapacitating intermittent claudication or critical limb ischemia. The main advantages of the endovascular approach are the low complication rate, high rate of technical success and a good clinical outcome. Biliary stenting has improved the clinical status of severely ill patients with bile duct stricture before major surgery, and represents a good palliative therapy in the case of malignant biliary obstruction.

    The advent of simulated surgical skills courses has brought dynamic changes to the traditional approach to acquiring practical skills in surgery. Teaching is a core part of the surgical profession, and any trainee can be involved in the organisation of skills training courses. This paper outlines the importance of organising surgical skills courses for trainees, and provides a practical guide on how to do so within busy clinical environments. The paper examines how to plan a course, how to design the programme, and provides tips on faculty staff requirements, venue, finance and participants, with additional suggestions for assessment and evaluation. We recommend the organisation of skills courses to any trainee. By following key ground rules, the surgical trainee can enable the acquisition of advanced learning opportunities and the ability to demonstrate valuable organisational skills. © Blackwell Publishing Ltd 2012.

    Although prior research finds a robust link between delinquent behavior and expectations, or an adolescent's perceived likelihood of obtaining one's future goals, fewer studies have evaluated aspirations, or the perceived importance of achieving one's goals. In addition, few studies consider how individual traits such as impulsivity affect the degree to which expectations and aspirations motivate or deter delinquent behavior. We contribute to this body of research by evaluating the independent effects of expectations and aspirations, and the aspiration-expectation gap (i.e., strain) on delinquent behavior during the year following an adolescent's first arrest using a large (N = 1117), racially/ethnically diverse sample of male adolescents (46.55% Latino, 35.81% Black, 14.95% White, and 2.69% Other race). In addition, we considered how impulse control interacts with expectations, aspirations, and strain to motivate behavior. Our results indicated that both aspirations, expectations and strain uniquely influence criminal behavior. Importantly, aspirations interacted with impulse control, such that aspirations affected delinquency only among youth with higher impulse control. Our findings suggest that aspirations may only influence behavior if youth also have the psychosocial capabilities to consider their future aspirations when behaving in the present.

    The aim of this study was to examine predictors of mortality in patients 5 years after ischemic stroke, focusing on cognitive impairment, vulnerability, and vascular risk factors assessed at 6 months post stroke. Patients from the Action on Secondary Prevention Interventions and Rehabilitation in Stroke (ASPIRE-S) cohort were followed up 5 years post ischemic stroke. Vascular risk factors, cognitive impairment, and vulnerability were assessed at 6 months post stroke. Cognitive impairment was assessed using a cutoff score lower than 26 on the Montreal Cognitive Assessment (MoCA). Vulnerability was defined as a score of 3 or higher on the Vulnerable Elders Scale (VES). Mortality and date of death were ascertained using hospital records, death notifications, and contact with general practitioners. Predictors of mortality were explored using multivariate Cox proportional hazards models. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) are presented. Sixty-three of 256 patients (24.6%) assessed at 6 months post stroke had died within 5 years. Cognitive impairment (HR [95% CI]: 2.19 [1.42-3.39]), vulnerability (HR [95% CI]: 5.23 [2.92-9.36]), atrial fibrillation (AF) (HR [95% CI]: 2.31 [1.80-2.96]), and dyslipidemia (HR [95% CI]: 1.90 [1.10-3.27]) were associated with increased risk of 5-year mortality. Vulnerability, cognitive impairment, AF, and dyslipidemia at 6 months were associated with increased risks of mortality 5 years post ischemic stroke. Identification and management of these risk factors should be emphasized in poststroke care. Copyright © 2018 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Low- and middle-income countries carry a disproportionate share of the global burden of pediatric surgical disease and have limited local healthcare infrastructure and human resources to address this burden. Humanitarian efforts that have improved or provided access to necessary basic or emergency surgery for children in these settings have included humanitarian assistance and disaster relief, short-term surgical missions, and long-term projects such as building pediatric specialty hospitals and provider networks. Each of these efforts may also include educational initiatives designed to increase local capacity. This article will provide an overview of pediatric humanitarian surgical outreach including reference to available evidence-based analyses of these platforms and make recommendations for surgical outreach initiatives for children.

    Training and simulation are gaining importance in surgical education. Today, virtual reality surgery simulators provide sophisticated laparoscopic training scenarios and offer detailed assessment methods. This also makes simulators interesting for the application in surgical skills courses. The aim of the current study was to assess the suitability of a virtual surgery simulator for training and assessment in an established surgical training course. The study was conducted during the annual "Practical Course for Visceral Surgery" (Warnemuende, Germany). 36 of 108 course participants were assigned at random for the study. Training was conducted in 15 sessions over 5 days with 4 identical virtual surgery simulators (LapSim) and 2 standardised training tasks. The simulator measured 16 individual parameters and calculated 2 scores. Questionnaires were used to assess the test persons' laparoscopic experience, their training situation and the acceptance of the simulator training. Data were analysed with non-parametric tests. A subgroup analysis for laparoscopic experience was conducted in order to assess the simulator's construct validity and assessment capabilities. Median age was 32 (27 - 41) years; median professional experience was 3 (1 - 11) years. Typical laparoscopic learning curves with initial significant improvements and a subsequent plateau phase were measured over 5 days. The individual training sessions exhibited a rhythmic variability in the training results. A shorter night's sleep led to a marked drop in performance. The participants' different experience levels could clearly be discriminated ( ≤ 20 vs. > 20 laparoscopic operations; p ≤ 0.001). The questionnaire showed that the majority of the participants had limited training opportunities in their hospitals. The simulator training was very well accepted. However, the participants severely misjudged the real costs of the simulators that were used. The learning curve on the

    Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus. Cytotoxicity and mutagenicity are other concerns. Minimisation of the production of surgical smoke and modification of any evacuation systems are possible solutions. In general, a surgical mask can provide more than 90% protection to exposure to surgical smoke; however, in most circumstances it cannot provide air-tight protection to the user. An at least N95 grade or equivalent respirator offers the best protection against surgical smoke, but whether such protection is necessary is currently unknown.

    Surgical education is changing owing to workforce and economic demands. Simulation and other technical teaching methods are used to acquire skills transferable to the operating room. Operative management of traumatic injuries has declined, making it difficult to acquire and maintain competence. The ASSET course was developed by the Committee on Trauma's Surgical Skills Committee to fill a surgical skills need in resident and fellow education. Using a human cadaver, standardized rapid exposure of vital structures in the extremities, neck, thorax, abdomen, retroperitoneum, and pelvis is taught. A retrospective analysis of 79 participants in four ASSET courses was performed. Operative experience data were collected, and self-efficacy questionnaires (SEQs) were administered before and after the course. Course evaluations and instructor evaluation data were analyzed. Student's and paired samples t tests as well as analysis of variance and Spearman ρ correlation coefficient analysis were performed using α at p ASSET course would teach new surgical techniques and that learner self-assessed ability would improve. Participants included 27 PGY-4, 20 PGY-5, 24 PGY-6 or PGY-7 and PGY-8 at other levels of training. Self-assessed confidence improved in all body regions (p knowledge rated at 4.8 and learning new techniques at 4.72. A standardized cadaver-based surgical exposures course offered to senior surgical residents adds new surgical skills and improves participant self-assessed ability to perform emergent surgical exposure of vital structures.

    To develop a reverse transcriptase-polymerase chain reaction (RT-PCR) assay to detect canine melanoma-associated antigens (MAAs) and to use this technique to screen aspirates of lymph nodes (LNs) for evidence of metastatic spread of oral malignant melanoma. 7 dogs with oral malignant melanoma and 4 dogs with multicentric lymphosarcoma. We prepared cDNA from melanoma tumor biopsies and fine-needle aspirates obtained from submandibular LNs of dogs with oral malignant melanoma or multicentric lymphosarcoma. The RT-PCR assay was performed by use of tyrosinase, Melan-A, gp100, tyrosinase-related protein 2 (TRP-2), or melanoma antigen-encoding gene B (MAGE-B)-specific primers. We detected MAGE-B mRNA in canine testicular tissue but not in melanoma biopsy specimens. Tyrosinase, Melan-A, gp100, and TRP-2 mRNAs were detected in tumor biopsy specimens and in 2 of 5 LN aspirates from dogs with melanoma, suggesting metastatic spread in those 2 dogs. We did not detect MAAs in LN aspirates obtained from dogs with multicentric lymphosarcoma. Sequencing of canine Melan-A and gp100 PCR products confirmed the specificity of the assay for these genes. Clinical staging of dogs with oral malignant melanoma is useful to assist in designing appropriate treatments. However, results of histologic examination of LN biopsy specimens can be inconclusive and, in humans, can underestimate the number of patients with metastatic disease. Molecular staging of melanomas in dogs can be achieved by screening LN aspirates for MAA mRNA, and this can be performed in combination with cytologic examination to aid in detection of metastatic disease.

    The aim of this study was to compare the efficacy of ultrasound guided aspiration of hydrosalpinx fluid at the time of oocyte retrieval with salpingectomy in the management of patients with ultrasound visible hydrosalpinx undergoing IVF-ET. One hundred and sixty patients with ultrasound visible hydrosalpinx were randomized into salpingectomy group and aspiration group using computer generated randomization list and sequentially numbered sealed envelopes containing allocation information written on a card. The clinical pregnancy rate per started cycle and the implantation rate were non- significantly higher in the salpingectomy group compared with the aspiration group [40% vs. 27.5% (p value = 0.132) and 18.95% vs. 12.82% (p value =0.124), respectively]. In the aspiration group, 34.21% of patients had rapid re-accumulation of the hydrosalpinx fluid (i.e. within first two weeks after embryo transfer). Whereas, the clinical pregnancy rate per transfer cycle and the implantation rate were significantly higher in salpingectomy group compared with the subgroup of patients with rapid re-accumulation of hydrosalpinx fluid [42.67% vs. 19.23% (p value = 0.036) and 18.95% vs. 7.58% (p value = 0.032), respectively], no significant differences were detected between the salpingectomy group and the subgroup of patients with no re-accumulation of hydrosalpinx fluid (42.67% vs. 34% (p value = 0.356) and 18.95% vs. 15.5% (p value = 0.457), respectively). The small sample size could be the cause of failure of detecting significant increase in implantation and pregnancy rates in salpingectomy group compared with aspiration group. Further larger randomized controlled trials are needed to determine whether salpingectomy is more effective than aspiration of hydrosalpinx fluid or not. Moreover, the data presented in this study suggested that rapid re-accumulation of hydrosalpinx fluid is an obstacle against successful implantation and the cause of lower success rate

    Gossypiboma or retained surgical sponge is an infrequently encountered surgical complication, more so in the head and neck region. A literature search did not reveal a previously reported case of retained or concealed surgical sponge after microscopic ear surgery. We present a unique and previously unreported case of a 25-year-old male who presented with a cystic swelling in the right supra-aural region 5 months post-modified radical mastoidectomy of the right ear. Surgical excision of the swelling revealed a retained surgical sponge. We emphasise the importance of counting surgical sponges after every surgical step to minimise the incidence of such retained surgical items.

    Cystic echinococcosis (CE) is a globally distributed zoonosis caused by the Echinococcus granulosus sensu lato species complex. Four approaches are available for treatment of abdominal CE: surgery, percutaneous aspiration, chemotherapy with albendazole, and watch-and-wait. Allocation of patients to these different treatment options mainly depends on the stage of the cystic lesion. However, as available guidelines are not widely followed, surgery is often applied even without the correct indication outside referral centers. This is not only a disadvantage for the patient, but also a waste of money. In this study, we evaluated the cost of the surgical approach for abdominal CE by analyzing hospitalization costs for 14 patients admitted to the General Surgery Ward at the "San Matteo" Hospital Foundation in Pavia, Italy, from 2008 through 2014. We found that the total cost of a single hospitalization, including hospital stay, surgical intervention, personnel, drugs, and administrative costs ranged from €5,874 to 23,077 (median €11,033) per patient. Our findings confirm that surgery can be an expensive option. Therefore, surgical intervention should be limited to cyst types that do not benefit from nonsurgical therapies and appropriate case management can best be accomplished by using a cyst stage-specific approach. © The American Society of Tropical Medicine and Hygiene.

    2003-06-01

    Fine-needle aspiration cytology (FNAC) was performed on a large scale at Memorial Hospital, New York, during the 1930s, but during the ensuing years, it did not gain much encouragement in United States. The technique had a resurgence in Scandinavia during the 1950s and 1960s, where it flourished before spreading to other parts of the world. It had also a revival in the United States, which contributed enormously to this tool in each and every aspect. The status of FNA during 1966-2002 was assessed through review of MEDLINE search data on FNA and its correlation with World Bank website data on classification of countries. A total of 849 journals published 5,609 articles on FNA over a period of 37 years. Both the number of publishing journals and the number of published articles on FNA were low during the 1960s (3.5 +/- 0.58 and 4.0 +/- 0.82, respectively) and 1970s (20.3 +/- 14.72 and 25.0 +/- 20.54, respectively), but their number increased sharply from the 1980s onward (78.2 +/- 25.65 and 147.2 +/- 66.89, respectively, during the 1980s, 126.2 +/- 11.94 and 301.4 +/- 35.99, respectively, during the 1990s, and 113.3 +/- 36.46 and 287.3 +/- 85.93, respectively, during the 2000s). The difference between the decades of 1960s-2000s, with respect to the number of publishing journals and published articles, was highly significant (P big public sector hospitals, and even in private clinics and laboratories. The number of centers practicing FNAC increased sharply during 1980s, as evident from the response of 69 laboratories in various parts of India to a questionnaire. As of 1998, 55.9% of the laboratories performed >/=1,000 cases of FNA per year. In 46% of the centers, pathologists alone performed the FNAC, whereas in 51%, they performed it in collaboration with radiologists and surgeons. Disposable syringes and needles were used in all the centers, but syringe holders were used in only in 61% of centers. In 86% of laboratories, two or more routine stains were used, and

    In order to elucidate the correlation of gastroesophageal reflex (GER) with aspiration pneumonia after surgery, 48 patients (mean, 75.6 years) with gastric cancer treated at the hospital from March, 1994 to December, 1994 were subjected to this prospective study. The pharyngeal stimulation test, nutritional assessment, radionuclide esophageal scintigraphy (34 cases) were performed before surgery and relationship between those results and aspiration pneumonia were studied. Aspiration pneumonia occurred in 3 cases, and all of them were in, significantly, poor nutritional status, compared with other. A significant increase in the frequency of GER was observed when a naso-gastric tube (NGT) was placed, but surprisingly, all the patients with aspiration pneumonia were 3 out of 4 patients who had continuous GER without NGT. It is noteworthy, continuous GER without NGT was significantly (p<0.001) affected postoperative aspiration pneumonia and impaired phalyngeal reflex was frequently correlated with development of aspiration pneumonia, when malnutritional status existed.

    To examine the on-call emergency workload of a general surgical team at a tertiary care teaching hospital to guide planning and provision of better surgical services. During six months period from August to January 2007; all emergency calls attended by general surgical team of Surgical Unit II in Accident and Emergency department (A and E) and in other units of Civil, Hospital Karachi, Pakistan were prospectively recorded. Data recorded includes timing of call, diagnosis, operation performed and outcome apart from demography. Total 456 patients (326 males and 130 females) were attended by on-call general surgery team during 30 emergency days. Most of the calls, 191 (41.9%) were received from 8 am to 5 pm. 224 (49.1%) calls were of abdominal pain, with acute appendicitis being the most common specific pathology in 41 (9.0%) patients. Total 73 (16.0%) calls were received for trauma. Total 131 (28.7%) patients were admitted in the surgical unit for urgent operation or observation while 212 (46.5%) patients were discharged from A and E. 92 (20.1%) patients were referred to other units with medical referral accounts for 45 (9.8%) patients. Total 104 (22.8%) emergency surgeries were done and the most common procedure performed was appendicectomy in 34 (32.7%) patients. Major workload of on-call surgical emergency team is dealing with the acute conditions of abdomen. However, significant proportion of patients are suffering from other conditions including trauma that require a holistic approach to care and a wide range of skills and experience. These results have important implications in future healthcare planning and for the better training of general surgical residents.

    2014-01-01

    Full Text Available Background: Granular cell tumors (GCT formerly known as Abrikossoff tumor or granular cell myoblastoma, are rare neoplasms encountered in the fine needle aspiration (FNA service. Named because of their highly granular cytoplasm which is invariably positive for the S-100 antibody, the classic GCT is thought to be of neural origin. The cytomorphological features range from highly cellular to scanty cellular smears with dispersed polygonal tumor cells. The cells have abundant eosinophilic granular cytoplasm, eccentric round to oval vesicular nuclei with small inconspicuous nucleoli. The fragility of the cells can result in many stripped nuclei in a granular background. The differential diagnosis occasionally can range from a benign or reactive process to features that are suspicious for malignancy. Some of the concerning cytologic features include necrosis, mitoses and nuclear pleomorphism. Methods: We identified 6 cases of suspected GCT on cytology within the last 10 years and compared them to their final histologic diagnoses. Results: Four had histologic correlation of GCT including one case that was suspicious for GCT on cytology and called atypical with features concerning for a malignant neoplasm. Of the other two cases where GCT was suspected, one showed breast tissue with fibrocystic changes, and the other was a Hurthle cell adenoma of the thyroid. Conclusions: These results imply that FNA has utility in the diagnosis of GCT, and should be included in the differential diagnoses when cells with abundant granular cytoplasm are seen on cytology. Careful attention to cytologic atypia, signs of reactive changes, use of immunohistochemistry, and clinical correlation are helpful in arriving at a definite diagnosis on FNA cytology.

    To test whether routine quantitative cultures of endotracheal aspirates obtained before the onset of ventilator-associated pneumonia (VAP) could help to predict the causative microorganisms and to select early appropriate antimicrobial therapy before obtaining BAL culture results. Prospective observational study. French medical ICU. A total of 299 patients received mechanical ventilation for at least 48 h. Endotracheal aspiration (EA) was performed twice weekly in all mechanically ventilated patients. A diagnosis of VAP was made by BAL culture. Only the EA performed just before the suspicion of VAP (EA-pre) were evaluated. This strategy (ie, the EA-pre-based strategy) was compared with an antibiotic therapy that would have been prescribed if the recommendations of both the American Thoracic Society (ATS) and Trouillet et al (Am J Respir Crit Care Med 1998; 157:531-539) had been applied. VAP was diagnosed (by BAL culture) in 41 of the 75 patients in whom BAL was performed. Among the 41 BAL specimens that were positive for VAP, EA-pre had identified the same microorganisms (with the same antibiotic resistance patterns) in 34 cases (83%). In one case, EA-pre was not available at the time BAL was performed (a case of early-onset VAP), but the empiric antibiotic therapy was adequate. While EA-pre did not give the same results as the BAL culture, the antibiotic therapy based on the results of the EA-pre was adequate in four other cases. Finally, antibiotic therapy was delayed in only two cases. Antibiotic treatment was therefore adequate in 38 of the 40 assessable cases (95%). If the Trouillet-based strategy had been used, the antibiotic treatment would have been adequate in 34 of the 41 cases (83%; p = 0.15 [vs EA-pre strategy]). Based on the ATS classification, the antibiotic treatment would have been adequately prescribed in only 28 of the 41 cases (68%; p = 0.005 [vs EA-pre strategy]). Routine EA performed twice a week makes it possible to prescribe adequate

    Full Text Available Tendon pathologies are a group of musculoskeletal conditions frequently seen in clinical practice. They can be broadly classified into traumatic, degenerative and overuse-related tendinopathies. Rotator cuff tears, Achilles tendinopathy and tennis elbow are common examples of these conditions. Conventional treatments have shown inconsistent outcomes and might fail to provide satisfactory clinical improvement. With the growing trend towards the use of mesenchymal stem cells (MSCs in other branches of medicine, there is an increasing interest in treating tendon pathologies using the bone marrow MSC. In this article, we provide a systematic literature review documenting the current status of the use of bone marrow aspirate concentrate (BMAC for the treatment of tendon pathologies. We also asked the question on the safety of BMAC and whether there are potential complications associated with BMAC therapy. Our hypothesis is that the use of BMAC provides safe clinical benefit when used for the treatment of tendinopathy or as a biological augmentation of tendon repair. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA checklist while preparing this systematic review. A literature search was carried out including the online databases of PubMed, EMBASE, ClinicalTrial.gov and the Cochrane Library from 1960 to the end of May 2015. Relevant studies were selected and critically appraised. Data from eligible studies were extracted and classified per type of tendon pathology. We included 37 articles discussing the application and use of BMAC for the treatment of tendon pathologies. The Critical Appraisal Skills Program (CASP appraisal confirmed a satisfactory standard of 37 studies. Studies were sub-categorised into: techniques of extraction, processing and microscopic examination of BMAC (n = 18, where five studies looked at the evaluation of aspiration techniques (n = 5, augmentation of rotator cuff tears (n = 5

    Contrast agents are an integral component of the video fluoroscopic swallow study. Agents commonly used include barium sulfate (E-Z Paque), iodixanol (Visipaque), and diatrizoic acid (Gastrografin). Barium is water insoluble, whereas iodixanol and diatrizoic acid are water-soluble iodine-based agents. The detrimental effect of these agents on the lungs has not been systematically evaluated. Our aim was to evaluate and compare the effects of aspirated barium, iodixanol, and diatrizoic acid on pulmonary injury in a lagomorph model. Animal model. Twenty adult male New Zealand White rabbits were divided into four groups (n = 5). Group 1 received 3 mL of barium sulfate injected into the trachea for 3 consecutive days. Group 2 received 3 mL of iodixanol injected into the trachea for 3 consecutive days. Group 3 received 3 mL of diatrizoic acid injected into the trachea for 3 consecutive days. A control group received 3 mL of air injected into the trachea under an identical protocol. All animals were euthanized on day 4, and the lung and trachea were harvested for blinded histopathologic analysis. The primary outcome measure was survival. The secondary endpoint was a blinded, histologic grading system of lung injury. Two animals in the barium group, one in the diatrizoic acid group, and 0 animals in the iodixanol and control groups died. The overall lung injury score for the barium (60.60 ± 6.34) and iodixanol groups (52.30 ± 3.11) were significantly higher (worse) than the diatrizoic acid (49.60 ± 7.64) and control groups (37.80 ± 3.56) (P barium sulfate (E-Z Paque) over 3 consecutive days causes more severe lung injury in a lagomorph model than 3 mL of aspirated iodixanol (Visipaque) and diatrizoic acid (Gastrografin). Diatrizoic acid caused the least histologic evidence of lung injury. NA Laryngoscope, 127:E148-E152, 2017. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

    Pressures on surgical education from restricted working hours and increasing scrutiny of outcomes have been compounded by the development of highly technical surgical procedures requiring additional specialist training. Mental training (MT), the act of performing motor tasks in the 'mind's eye', offers the potential for training outside the operating room. However, the technique is yet to be formally incorporated in surgical curricula. This study aims to review the available literature to determine the role of MT in surgical education. EMBASE and Medline databases were searched. The primary outcome measure was surgical proficiency following training. Secondary analyses examined training duration, forms of MT and trainees level of experience. Study quality was assessed using Consolidated Standards of Reporting Trials scores or Quality Assessment Tool for Before-After (Pre-Post) Studies with No Control Group. Fourteen trials with 618 participants met the inclusion criteria, of which 11 were randomized and three longitudinal. Ten studies found MT to be beneficial. Mental rehearsal was the most commonly used form of training. No significant correlation was found between the length of MT and outcomes. MT benefitted expert surgeons more than medical students or novice surgeons. The majority studies demonstrate MT to be beneficial in surgical education especially amongst more experienced surgeons within a well-structured MT programme. However, overall studies were low quality, lacked sufficient methodology and suffered from small sample sizes. For these reasons, further research is required to determine optimal role of MT as a supplementary educational tool within the surgical curriculum. © 2017 Royal Australasian College of Surgeons.

    Full Text Available Objective. To study the patient profile for symptomatic peripheral lymphadenopathy in terms of histopathological findings and demography and evaluate the yield, relevance, and outcomes of peripheral lymph node biopsy (PLNB as a diagnostic step in a remote setup in the absence of less invasive options like fine-needle aspiration cytology (FNAC or ultrasonogram- (USG- guided FNAC. Methods. A retrospective review of patients undergoing PLNB between 1 May 2011 and 30 April 2013 was done. Demographics, histopathological reports, and outcomes were studied. Results. Of 132 patients, 51 (38.63% were male and 81 (61.36% were female. There were 48 (36.3% patients in the age group less than 16 years, and 84 (63.6% were beyond 16 years. The commonest site of biopsy was the neck in 114 (86.36% patients. The histopathological diagnosis was tuberculosis (TB in 60 (45.45% patients, reactive lymphadenitis in 29 (21.9%, nonspecific granuloma in 18 (13.6%, lymphoma in 7 (5.3%, acute lymphadenitis in 7 (5.3%, metastatic secondary in 3 (2.2%, and other benign causes in 8 (6.06%. Conclusions. PLNB is a procedure with good diagnostic yield in evaluation of peripheral lymphadenopathy. Its relevance is appreciable in a remote setup where less invasive options are unavailable. Its simplicity and lack of mortality/significant morbidity make it a valid option in rural surgical practice.

    Full Text Available We reviewed the current status of thyroid fine-needle aspiration cytology (FNAC in Korea. Thyroid aspiration biopsy was first introduced in Korea in 1977. Currently, radiologists aspirate the thyroid nodule under the guidance of ultrasonography, and cytologic interpretation is only legally approved when a cytopathologist makes the diagnosis. In 2008, eight thyroid-related societies came together to form the Korean Thyroid Association. The Korean Society for Cytopathology and the endocrine pathology study group of the Korean Society for Pathologists have been updating the cytologic diagnostic guidelines. The Bethesda System for Reporting Thyroid Cytopathology was first introduced in 2009, and has been used by up to 94% of institutions by 2016. The average diagnosis rates are as follows for each category: I (12.4%, II (57.9%, III (10.4%, IV (2.9%, V (3.7%, and VI (12.7%. The malignancy rates in surgical cases are as follows for each category: I (28.7%, II (27.8%, III (50.6%, IV (52.3%, V (90.7%, and VI (100.0%. Liquid-based cytology has been used since 2010, and it was utilized by 68% of institutions in 2016. The categorization of thyroid lesions into “atypia of undetermined significance” or “follicular lesion of undetermined significance” is necessary to draw consensus in our society. Immunocytochemistry for galectin-3 and BRAF is used. Additionally, a molecular test for BRAF in thyroid FNACs is actively used. Core biopsies were performed in only 44% of institutions. Even the institutions that perform core biopsies only perform them for less than 3% of all FNACs. However, only 5% of institutions performed core biopsies up to three times more than FNAC.

    Research on academic cheating by high school students and undergraduates suggests that many students will do whatever it takes, including violating ethical classroom standards, to not be left behind or to race to the top. This behavior may be exacerbated among pre-med and pre-health professional school students enrolled in laboratory classes because of the typical disconnect between these students, their instructors and the perceived legitimacy of the laboratory work. There is little research, however, that has investigated the relationship between high aspirations and academic conduct. This study fills this research gap by investigating the beliefs, perceptions and self-reported academic conduct of highly aspirational students and their peers in mandatory physics labs. The findings suggest that physics laboratory classes may face particular challenges with highly aspirational students and cheating, but the paper offers practical solutions for addressing them.

    2006-09-01

    Rehabilitation of voice and speech after total laryngectomy has become established practice in recent years. A voice prosthesis is placed within a surgically produced fistula between the trachea and upper oesophagus and acts as a one way valve, allowing passage of pulmonary air from the trachea into the oesophagus and preventing aspiration of food and fluid from the oesophagus into the trachea. Persistent leakage through or around these prostheses is a recognized complication, the aetiology of which can vary widely, from mechanical issues with the prostheses themselves to anatomical and physiological issues associated with the reconstructed pharynx. We report a new technique of using Dysport in the management of intractable central leakage due to premature and forceful closure of the upper oesophageal sphincter during swallowing. This resulted in the pooling of fluids around the posterior flange of the prosthesis. This, along with the increased pressure from the muscle contraction, led to central leakage, as identified on videofluoroscopy. An injection of Dysport paralysed the upper oesophageal sphincter, preventing pooling of fluids around the prosthesis and the forcing open of the valve. The effect was to eliminate the leakage, and the patient did not require further injections over the following 22 months.

    Background and Aim. A successful endoscopic ultrasound guided rendezvous (EUS-RV) biliary drainage is dependent on accurate puncture of the bile duct and precise guide wire manipulation across the ampulla of Vater. We aim to study the feasibility of using a flexible 19-gauge fine aspiration needle in the performance of EUS-RV biliary drainage. Method. This is a retrospective case series of EUS-RV biliary drainage procedures at a single center. Patients who failed ERCP during the same session for benign or malignant biliary obstruction underwent EUS-RV using a flexible, nitinol covered, 19-gauge needle for biliary access and guide wire manipulation. Result. 24 patients underwent EUS-RV biliary drainage via extrahepatic access while 1 attempt was via intrahepatic access. The technical success rate was 80%, including 83.3% of cases via extrahepatic access. There was no significant difference in success rate of inpatient and outpatient procedures, benign or malignant indications, or type of guide wire used. Adverse events included mild pancreatitis (3 patients) and cholangitis (1 patient). Conclusion. A flexible 19-gauge needle for biliary access can be safe and effective when used to perform EUS-RV biliary drainage. Direct comparison between the nitinol needle and conventional metal needles in the performance of EUS guided biliary drainage is needed.

    Gynecomastia is defined as the benign enlargement of the male breast. Most studies on surgical treatment of gynecomastia show only small series and lack histopathology results. The aim of this study was to analyze the surgical approach in the treatment of gynecomastia and the related outcome over a 10-year period. All patients undergoing surgical gynecomastia corrections in our department between 1996 and 2006 were included for retrospective evaluation. The data were analyzed for etiology, stage of gynecomastia, surgical technique, complications, risk factors, and histological results. A total of 100 patients with 160 operations were included. Techniques included subcutaneous mastectomy alone or with additional hand-assisted liposuction, isolated liposuction, and formal breast reduction. Atypical histological findings were found in 3% of the patients (spindle-cell hemangioendothelioma, papilloma). The surgical revision rate among all patients was 7%. Body mass index and a weight of the resected specimen higher than 40 g were identified as significant risk factors for complications (p gynecomastia requires an individualized approach. Caution must be taken in performing large resections, which are associated with increased complication rates. Histological tissue analysis should be routinely performed in all true gynecomastia corrections, because histological results may reveal atypical cellular pathology.

    Bibliometric analysis highlights the key topics and publications, which have shaped surgical education. Here, the 100 most cited articles in the arena of surgical education were analyzed. Thomson Reuters Web of Science was interrogated using the keyword search terms "surgery" and ("learning" or "skills" or "competence" or "assessment" or "training" or "procedure-based assessments" or "performance" or "technical skills" or "curriculum" or "education" or "mentoring"] to identify all English language full articles, and the 100 most cited articles were analyzed by topic, journal, author, year, institution, and country of origin. A total of 403,733 eligible articles were returned and the median citation number was 164 (range: 107-1018). The most cited article (by Seymour, Yale University School of Medicine, Annals of Surgery, 1018 citations) focused on the use of virtual reality surgical simulation training. Annals of Surgery published the highest number of articles and received the most citations (n = 16, 3715 citations). The countries with the greatest number of publications were the USA (n = 45), Canada (n = 19), and the UK (n = 18). The commonest topics included simulation (n = 45) and assessment of clinical competence (n = 40). Surgical skill acquisition and assessment was the area of focus of 85% of the most cited contemporary articles, and this study provides the most cited references, serving as a guide as to what makes a citable published work in the field of surgical education.

    Incisional endometriosis (IE) is a rare entity reported in 0.03-1.08% of women following obstetric or gynecologic surgeries. Most cases reported in literature have appeared after cesarean sections and were often clinically mistaken for hernia, abscess, suture granuloma or lipoma. We hereby report a case of IE following a second trimester hysterotomy, which was diagnosed by fine needle aspiration cytology (FNAC). Our patient was 26 years old, presenting with a mass over anterior abdominal wall, associated with incapacitating pain during each menstrual cycle. FNAC showed epithelial cells, stromal cells and hemosiderin laden macrophages. Based on the typical history, clinical and cytological features, the diagnosis of IE was established. Wide surgical excision was done and the resulting rectus sheath defect was repaired. Patient was followed for 6 months during which time she was symptom free. This article also reviews the spectrum of cytological features and the rare possibility of malignant transformation that can occur in IE.

    Full Text Available Sedation during invasive procedures not only provides appropriate humanitarian care for patients, but also facilitates the completion of invasive procedures. Although generally safe and effective, adverse effects may occur especially in patients with co-morbid diseases. We present the successful use of a combination of dexmedetomidine and ketamine to provide sedation and analgesia in a 21-year-old patient with Duchenne muscular dystrophy (DMD undergoing bone marrow aspiration and biopsy. Co-morbidities included both depressed myocardial function and impaired respiratory function. Dexmedetomidine was administered as a loading dose of 1 μg/kg over 5 min followed by an infusion of 1 μg/kg/h. Ketamine (20 mg was administered along with the dexmedetomidine loading dose. An additional 10 mg of ketamine was administered to treat the pain experienced during the placement of the local anesthetic agent prior to the procedure. No clinically significant hemodynamic or respiratory changes were noted. The patient tolerated the procedure well and was discharged home. A review of previously published reports of dexmedetomidine and ketamine for procedural sedation are reviewed.

    Some microbes, including the Bacteroides species, Staphylococcus aureus and Streptococcus milleri groups, can cause pulmonary abscess. Haemophilus parainfluenzae is usually categorized as one of the normal flora which colonizes in the ears and the nasopharynx, and it has been long considered that H. parainfluenzae has little pathogenicity in the lower respiratory tract and lung parenchymal. In this report, we present a case of pulmonary abscess caused by both H. parainfluenzae and Streptococcus intermedius. The patient was a 75-year-old man who had had total esophageo-gastrectomy because of esophageal cancer. He presented with purulent sputum, and chest X-ray film showed a dense consolidation in the right upper lung field. CT-guided transcutaneous fine needle aspiration was performed as a diagnostic procedure. Since both H. parainfluenzae and S. intermedius had been isolated from the lesion, pulmonary abscess caused by these two pathogens was diagnosed. The patient was treated with panipenem/betamipron, and his symptoms and pulmonary infiltrates on the chest X-ray film improved thereafter. So far, very few cases have been reported in which H. parainfluenzae caused lower respiratory tract infection. Although S. intermedius is known as one of the pathogens of pulmonary abscess, it is possible that H. parainfluenzae could also be pathogenic in infectious diseases of the lung.

    Full Text Available Abstract Background Detection of cytologic atypia in nipple aspirate fluid (NAF has been shown to be a predictor of risk for development of breast carcinoma. Manual collection of NAF for cytologic evaluation varies widely in terms of efficacy, ease of use, and patient acceptance. We investigated a new automated device for the non-invasive collection of NAF in the office setting. Methods A multi-center prospective observational clinical trial involving asymptomatic women designed to assess fluid production, adequacy, safety and patient acceptance of the HALO NAF Collection System (NeoMatrix, Irvine, CA. Cytologic evaluation of all NAF samples was performed using previously described classification categories. Results 500 healthy women were successfully enrolled. Thirty-eight percent (190/500 produced fluid and 187 were available for cytologic analysis. Cytologic classification of fluid producers showed 50% (93/187 Category 0 (insufficient cellular material, 38% (71/187 Category I (benign non-hyperplastic ductal epithelial cells, 10% (18/187 Category II (benign hyperplastic ductal epithelial cells, 3% (5/187 Category III (atypical ductal epithelial cells and none were Category IV (unequivocal malignancy. Overall, 19% of the subjects produced NAF with adequate cellularity and 1% were found to have cytologic atypia. Conclusion The HALO system is a simple, safe, rapid, automated method for standardized collection of NAF which is acceptable to patients. Cytologic assessment of HALO-collected NAF showed the ability to detect benign and pre-neoplastic ductal epithelial cells from asymptomatic volunteers.

    Background Accurate Diagnosis of Breast Cancer is of prime importance. Fine Needle Aspiration test or "FNA”, which has been used for several years in Europe, is a simple, inexpensive, noninvasive and accurate technique for detecting breast cancer. Expending the suitable features of the Fine Needle Aspiration results is the most important diagnostic problem in early stages of breast cancer. In this study, we introduced a new algorithm that can detect breast cancer based on combining artificial intelligent system and Fine Needle Aspiration (FNA). Methods We studied the Features of Wisconsin Data Base Cancer which contained about 569 FNA test samples (212 patient samples (malignant) and 357 healthy samples (benign)). In this research, we combined Artificial Intelligence Approaches, such as Evolutionary Algorithm (EA) with Genetic Algorithm (GA), and also used Exact Classifier Systems (here by Fuzzy C-Means (FCM)) to separate malignant from benign samples. Furthermore, we examined artificial Neural Networks (NN) to identify the model and structure. This research proposed a new algorithm for an accurate diagnosis of breast cancer. Results According to Wisconsin Data Base Cancer (WDBC) data base, 62.75% of samples were benign, and 37.25% were malignant. After applying the proposed algorithm, we achieved high detection accuracy of about "96.579%” on 205 patients who were diagnosed as having breast cancer. It was found that the method had 93% sensitivity, 73% specialty, 65% positive predictive value, and 95% negative predictive value, respectively. If done by experts, Fine Needle Aspiration (FNA) can be a reliable replacement for open biopsy in palpable breast masses. Evaluation of FNA samples during aspiration can decrease insufficient samples. FNA can be the first line of diagnosis in women with breast masses, at least in deprived regions, and may increase health standards and clinical supervision of patients. Conclusion Such a smart, economical, non-invasive, rapid

    Surgery simulation is a promising technique for training of surgical procedures. The overall goal for any surgical simulator is to allow for efficient training of the skills required and to improve learning by giving the user proper feedback. This goal is easier achieved if the training is performed in a realistic environment. Therefore functionality such as soft tissue deformation, tearing and cutting, penetration of soft tissue etc. is necessary. Furthermore, a realistic simulator must provide haptic feedback so that all senses match, that is, there should be a correspondence between what you see and what you feel with your hands. In this paper we describe a medical platform that provides all this functionality. It is based on the Reachln Magma API, which has been extended for surgery simulation. We describe the development of the platform and illustrate the use of it for the development of two different types of surgical simulators, both of which represents work in progress.

  19. Providing surgical care in Somalia: A model of task shifting.

    Somalia is one of the most political unstable countries in the world. Ongoing insecurity has forced an inconsistent medical response by the international community, with little data collection. This paper describes the "remote" model of surgical care by Medecins Sans Frontieres, in Guri-El, Somalia. The challenges of providing the necessary prerequisites for safe surgery are discussed as well as the successes and limitations of task shifting in this resource-limited context. In January 2006, MSF opened a project in Guri-El located between Mogadishu and Galcayo. The objectives were to reduce mortality due to complications of pregnancy and childbirth and from violent and non-violent trauma. At the start of the program, expatriate surgeons and anesthesiologists established safe surgical practices and performed surgical procedures. After January 2008, expatriates were evacuated due to insecurity and surgical care has been provided by local Somalian doctors and nurses with periodic supervisory visits from expatriate staff. Between October 2006 and December 2009, 2086 operations were performed on 1602 patients. The majority (1049, 65%) were male and the median age was 22 (interquartile range, 17-30). 1460 (70%) of interventions were emergent. Trauma accounted for 76% (1585) of all surgical pathology; gunshot wounds accounted for 89% (584) of violent injuries. Operative mortality (0.5% of all surgical interventions) was not higher when Somalian staff provided care compared to when expatriate surgeons and anesthesiologists. The delivery of surgical care in any conflict-settings is difficult, but in situations where international support is limited, the challenges are more extreme. In this model, task shifting, or the provision of services by less trained cadres, was utilized and peri-operative mortality remained low demonstrating that safe surgical practices can be accomplished even without the presence of fully trained surgeon and anesthesiologists. If security improves

    The aim of the present article was to systematically review the ethics of surgical innovation and introduce the components of the learning health care system to guide future research and debate on surgical innovation.Although the call for evidence-based practice in surgery is increasingly high on the agenda, most surgeons feel that the format of the randomized controlled trial is not suitable for surgery. Innovation in surgery has aspects of, but should be distinguished from both research and clinical care and raises its own ethical challenges.To answer the question "What are the main ethical aspects of surgical innovation?", we systematically searched PubMed and Embase. Papers expressing an opinion, point of view, or position were included, that is, normative ethical papers.We included 59 studies discussing ethical aspects of surgical innovation. These studies discussed 4 major themes: oversight, informed consent, learning curve, and vulnerable patient groups. Although all papers addressed the ethical challenges raised by surgical innovation, surgeons hold no uniform view of surgical innovation, and there is no agreement on the distinction between innovation and research. Even though most agree to some sort of oversight, they offer different alternatives ranging from the formation of new surgical innovation committees to establishing national registries. Most agree that informed consent is necessary for innovative procedures and that surgeons should be adequately trained to assure their competence to tackle the learning curve problem. All papers agree that in case of vulnerable patients, alternatives must be found for the informed consent procedure.We suggest that the concept of the learning health care system might provide guidance for thinking about surgical innovation. The underlying rationale of the learning health care system is to improve the quality of health care by embedding research within clinical care. Two aspects of a learning health care system might

  1. How useful is gastroesophageal reflux scintigraphy in suspected childhood aspiration

    It has been suggested that gastroesophageal reflux scintigraphy might be useful in assisting one in determining therapy for patients suspected of aspirating or becoming apneic secondary to gastroesophageal reflux. This, however, has not been our experience and in reviewing 23 patients with recurrent pneumonia and/or apnea who had gastroesophageal reflux scintigraphy, we were able to detect aspiration in only one. This was especially significant since 13 (59%) of these patients had demonstrable reflux, and of these, eight were treated successfully for suspected aspiration even though none was demonstrated isotopically. To be sure, the demonstration of pulmonary aspiration with gastroesophageal reflux scintigraphy had little influence on patient selection and response to therapy. For this reason we feel there is little justification in depending on the GRS for the specific purpose of trying to document pulmonary aspiration in infants and children who are refluxing. One of the more serious complications of gastroesophageal (GE) reflux is aspiration leading to recurrent pulmonary infections and/or apnea. However, it always has been difficult to demonstrate actual aspiration into the lungs, and to be sure, barium studies of the upper GI tract seldom reveal this complication. Recently, however, considerable interest has been generated in gastroesophageal scintigraphy (GRS) as a possible means of documenting such aspiration. Rationale for this stems from the fact that suspected patients can be studied over a longer period of time and in addition, delayed and overnight images can be obtained. However, our experience does not support GRS as being an adequate method for demonstrating aspiration.

    We aimed to evaluate the impact of thrombus aspiration (TA) during primary percutaneous coronary intervention (P-PCI) in 'real-world' settings. We performed a retrospective study, using data from the National Registry of Interventional Cardiology (RNCI 2006-2012, Portugal) with ST-elevation myocardial infarction (STEMI) patients treated with P-PCI. The primary outcome, in-hospital mortality, was analysed through adjusted odds ratio (aOR) and 95% confidence intervals (95%CI). We assessed data for 9458 STEMI patients that undergone P-PCI (35% treated with TA). The risk of in-hospital mortality with TA (aOR 0.93, 95%CI:0.54-1.60) was not significantly decreased. After matching patients through the propensity score, TA reduced significantly the risk of in-hospital mortality (OR 0.58, 95%CI:0.35-0.98; 3500 patients). The whole cohort data does not support the routine use of TA in P-PCI, but the results of the propensity-score matched cohort suggests that the use of selective TA may improve the short-term risks of STEMI.

    Solid pseudopapillary tumor of pancreas (SPTP) is a rare pancreatic tumor of uncertain histogenesis usually affecting young women. Though these tumors have characteristic cytomorphology, it is sometimes difficult to differentiate them from neuroendocrine tumors of the pancreas. We reviewed cases of SPTP to delineate the diagnostic cytological features and also observed utility of CD 99 (MIC 2) immunostaining to aid in the diagnosis of this tumor. This study was designed to demonstrate the utility of CD 99 immunostaining along with cytological features for making a pre-operative diagnosis and delineating it from the neuroendocrine tumor of pancreas which is a close mimic. Cytomorphological features of 11 cases of solid pseudopapillary neoplasm diagnosed by pre-operative fine-needle aspiration cytology (FNAC) at our institute were reviewed. Immunocytochemistry for CD 99 was also performed on the smears. All the cases had cellular smears with monomorphic cells lying singly, as loosely cohesive clusters as well as forming delicate pseudopapillae. Presence of intra and extra-cellular basement membrane material, background foamy macrophages and nuclear grooves were the other salient features. Immunocytochemistry for CD 99 could be performed on eight cases and demonstrated typical paranuclear dot-like positivity. Pre-operative early diagnosis of SPTP can be made by FNAC which can further be aided by CD 99 immunocytochemistry.

    Branchial cleft cysts occur because of a failure of involution of the second branchial cleft. However, as well-differentiated squamous cell carcinoma can mimic branchial cleft cysts, there is a lack of consensus on the appropriate management of cystic neck lumps. To report our experience of fine needle aspiration cytology and frozen section examination in the management of cystic neck lumps. Retrospective case note review of patients managed in the Southern General Hospital, Scotland, UK. The sensitivity of fine needle aspiration cytology and frozen section for detecting branchial cleft cysts was 75 per cent and 100 per cent respectively. Two patients who did not undergo intra-operative frozen section examination were either over- or under-treated, which is discussed. Adult patients subjected to surgical excision of a suspected branchial cyst should undergo intra-operative frozen section analysis regardless of clinical suspicion for malignancy. This part of management is critical to ensure patients are offered appropriate treatment.

    To evaluate methodological quality and the extent of concordance among meta-analysis and/or systematic reviews on surgical interventions for gastric cancer (GC). A comprehensive search of PubMed, Medline, EMBASE, the Cochrane library and the DARE database was conducted to identify the reviews comparing different surgical interventions for GC prior to April 2014. After applying included criteria, available data were summarized and appraised by the Oxman and Guyatt scale. Fifty six reviews were included. Forty five reviews (80.4%) were well conducted, with scores of adapted Oxman and Guyatt scale ≥ 14. The reviews differed in criteria for avoiding bias and assessing the validity of the primary studies. Many primary studies displayed major methodological flaws, such as randomization, allocation concealment, and dropouts and withdrawals. According to the concordance assessment, laparoscopy-assisted gastrectomy (LAG) was superior to open gastrectomy, and laparoscopy-assisted distal gastrectomy was superior to open distal gastrectomy in short-term outcomes. However, the concordance regarding other surgical interventions, such as D1 vs. D2 lymphadenectomy, and robotic gastrectomy vs. LAG were absent. Systematic reviews on surgical interventions for GC displayed relatively high methodological quality. The improvement of methodological quality and reporting was necessary for primary studies. The superiority of laparoscopic over open surgery was demonstrated. But concordance on other surgical interventions was rare, which needed more well-designed RCTs and systematic reviews.

    The clinical application of robotic surgery is increasing. The skills necessary to perform robotic surgery are unique from those required in open and laparoscopic surgery. A validated laparoscopic surgical skills curriculum (Fundamentals of Laparoscopic Surgery or FLS™) has transformed the way surgeons acquire laparoscopic skills. There is a need for a similar skills training and assessment tool for robotic surgery. Our research group previously developed and validated a robotic training curriculum in a virtual reality (VR) simulator. We hypothesized that novice robotic surgeons could achieve proficiency levels defined by more experienced robotic surgeons on the VR robotic curriculum, and that this would result in improved performance on the actual daVinci Surgical System™. 25 medical students with no prior robotic surgery experience were recruited. Prior to VR training, subjects performed 2 FLS tasks 3 times each (Peg Transfer, Intracorporeal Knot Tying) using the daVinci Surgical System™ docked to a video trainer box. Task performance for the FLS tasks was scored objectively. Subjects then practiced on the VR simulator (daVinci Skills Simulator) until proficiency levels on all 5 tasks were achieved before completing a post-training assessment of the 2 FLS tasks on the daVinci Surgical System™ in the video trainer box. All subjects to complete the study (1 dropped out) reached proficiency levels on all VR tasks in an average of 71 (± 21.7) attempts, accumulating 164.3 (± 55.7) minutes of console training time. There was a significant improvement in performance on the robotic FLS tasks following completion of the VR training curriculum. Novice robotic surgeons are able to attain proficiency levels on a VR simulator. This leads to improved performance in the daVinci surgical platform on simulated tasks. Training to proficiency on a VR robotic surgery simulator is an efficient and viable method for acquiring robotic surgical skills.

  8. Use of fine needle aspirate from peripheral nerves of pure-neural leprosy for cytology and PCR to confirm the diagnosis: A pilot study

    2013-01-01

    Full Text Available Background: The diagnosis of pure neural leprosy (PNL remained subjective because of over-dependence of clinical expertise and a lack of simple yet reliable diagnostic tool. The criteria for diagnosis, proposed by Jardim et al., are not routinely done by clinicians in developing country as it involves invasive nerve biopsy and sophisticated anti-PGL-1 detection. We conducted a study using fine needle aspiration cytology (FNAC coupled with Ziehl Neelsen staining (ZN staining and Multiplex- Polymerase Chain Reaction (PCR specific for M. leprae for an objective diagnosis of pure neural leprosy (PNL, which may be simpler and yet reliable. Aim: The aim of the study is to couple FNAC with ZN staining and multiplex PCR to diagnose pure neural leprosy patients rapidly, in simpler and yet reliable way. Methods: Thirteen patients of PNL as diagnosed by two independent consultants were included as case, and 5 patients other than PNL were taken as control in the study. Fine needle aspiration was done on the affected nerve, and aspirates were evaluated for cytology, ZN staining and multiplex- PCR. Results: Out of the 13 cases where fine needle aspiration was done, M. leprae could be elicited in the nerve tissue aspirates in 5 cases (38.4% with the help of conventional acid-fast staining and 11 cases (84.6% with the help of multiplex PCR. On cytological examination of the aspirates, only 3 (23% cases showed specific epithelioid cells, whereas 8 (61.5% cases showed non-specific inflammation, and 2 (15.3% cases had no inflammatory cells. Conclusion: Our study demonstrates that in the field of laboratory diagnosis of PNL cases, FNAC in combination with ZN staining for acid-fast bacilli (AFB and Multiplex-PCR can provide a rapid and definitive diagnosis for the majority of PNL cases. FNAC is a less-invasive, outdoor-based and simpler technique than invasive nerve biopsy procedure. Thus, this study may enlighten the future path for easy and reliable diagnosis of

    To investigate the role of endotracheal aspirate (EA) culture in the diagnosis and antibiotic management in ventilator-associated pneumonia (VAP). We searched CNKI, Wanfang, PUBMED and EMBASE databases published from January 1990 to December 2011, to find relevant literatures on VAP microbiological diagnostic techniques including EA and bronchoalveolar lavage (BALF). The following key words were used: ventilator associated pneumonia, diagnosis and adult. Meta-analysis was performed and the sensitivity and specificity of EA on VAP diagnosis were calculated. Our literature search identified 1665 potential articles, 8 of which fulfilled our selection criteria including 561 patients with paired cultures. Using BALF quantitative culture as reference standard, the sensitivity and specificity of EA were 72% and 71%. When considering quantitative culture of EA only, the sensitivity and specificity improved to 90% and 65%, while the positive and the negative predictive values were 68% and 89% respectively. However, the sensitivity and specificity of semi-quantitative culture of EA were only 50% and 80%, with a positive predictive value of 77% and a negative predictive value of 58% respectively. EA culture had relatively poor sensitivity and specificity, although quantitative culture of EA only could improve the sensitivity. Initiating therapy on the basis of EA quantitative culture may still result in excessive antibiotic usage. Our data suggested that EA could provide some information for clinical decision but could not replace the role of BALF quantitative culture in VAP diagnosis.

    Eosinophilic esophagitis (EoE) is diagnosed by microscopic findings of eosinophilic infiltration into the squamous epithelium. In contrast, another disease concept termed "eosinophilic esophageal myositis (EoEM)" has been proposed, whereby there is eosinophilic infiltration into the muscularis propria instead. A 60-year-old man was referred to our hospital for chest pain, dysphagia, and several episodes of esophageal food impaction. Although EoE was suspected based on clinical features, biopsy specimens showed no mucosal eosinophilic infiltration. Endoscopic ultrasound (EUS) showed thickening of the muscularis propria layer and subsequent EUS-guided fine-needle aspiration biopsy (EUS-FNA) revealed eosinophilic infiltration into the muscularis propria. Although the patient's symptoms gradually improved after steroid administration, complete remission was not achieved after 1 year of treatment. This case may reflect a disorder distinct from typical EoE based on eosinophilic infiltration of the muscularis propria but not the squamous epithelium, and we, therefore, diagnosed it as EoEM using the EUS-FNA findings as reference.

    Background To evaluate the influence of bone marrow aspirate concentrate (BMAC) on tendon-to-bone healing in a rabbit rotator cuff model and to characterize the composition of growth factors in BMAC. Methods In this in vivo study, 40 rabbits were allocated into five groups: control (C), repair + saline (RS), repair + platelet-rich plasma (PRP; RP), repair + BMAC (RB) and repair + PRP + BMAC (RPB). A tear model was created by supraspinatus tendon transection at the footprint. Six weeks after transection, the torn tendon was repaired along with BMAC or PRP administration. Six weeks after repair, shoulder samples were harvested for biomechanical and histological testing. Ten rabbits were used for processing PRP and BMAC, followed by analysis of blood cell composition and the levels of growth factors in vitro. Results The ultimate load-to-failure was significantly higher in RPB group compared to RS group (p = 0.025). BMAC-treated groups showed higher values of biomechanical properties than RS group. The histology of BMAC-treated samples showed better collagen fiber continuity and orientation than RS group. BMAC contained significantly higher levels of the several growth factors than PRP. Conclusions Locally administered BMAC enhanced tendon-to-bone healing and has potential for clinical applications. PMID:29564054

    This article describes the development and implementation of a rotation programme for Band 5 nurses within the surgical directorate at Heart of England NHS Foundation Trust. The article highlights the challenges raised for nurses with health service modernization and develops the rationale for the need for a different way of thinking. At Heart of England NHS Foundation Trust, the authors evaluation has led to the development of the surgical rotation programme for Band 5 nurses. This rotation programme challenged basic clinical practice and traditional modes of staff placement. Indications, so far, are that quality of care for patients has improved and nurses satisfaction has increased as a result of the implementation of the Band 5 surgical rotation programme.

    Full Text Available Objectives. Distal biceps tendon rupture affects the functional upperextremity movement, impairing supination and flexion strength. According to age, profession and additional risks treatment might be nonoperative or surgical. Methods. We describe the case of a 43 years old male patient who sustained an injury to his right distal biceps and was diagnosed with acute right distal biceps rupture. Surgical treatment was decided and biceps tendon was reinserted to the radius tuberosity using a combination of a cortical button fixation associated with an interference screw. Results. Postoperative functional result was favorable with no complications and with no movement limitation after one month. Conclusions. When possible, distal biceps tendon repair should be realized surgically because this permits restoring of the muscle strength to near normal levels with no loss of motion. Nerve complications are common; therefore the surgery should be realized by experienced upper extremity surgeons.

    Adults and children are required to fast before anaesthesia to reduce the risk of regurgitation and aspiration of gastric contents. However, prolonged periods of fasting are unnecessary and may cause complications. This study was conducted to evaluate preoperative fasting period in our centre and compare it with the ASA recommendations and factors that influence fasting periods. This is a cross-sectional study of preoperative fasting times among elective surgical patients. A total numbers of 260 patients were interviewed as they arrived at the reception area of operating theatre using questionnaire. Majority of patients (98.1%) were instructed to fast from midnight. Fifteen patients (5.8%) reported that they were told the importance of preoperative fasting. The mean fasting period were 15.9±2.5 h (range 12.0-25.3 h) for solids and 15.3±2.3 h (range 12.0-22.0 h) for liquids. The mean duration of fasting was significantly longer for patients operated after midday compared to those operated before midday, pfasting periods were 7.65 times longer for clear liquid and 2.5 times for solids than the ASA guidelines. It is imperative that the Hospital should establish Preoperative fasting policies and teach the staff who should ensure compliance with guidelines.

    Narratives of deindustrialization, urban decline and failing public housing and the negative outcomes associated with these processes dominate accounts of post-war Scotland, bolstering the interpretation of Scottish exceptionalism in a British context. Within these accounts working people appear as victims of powerful and long-term external forces suffering sustained and ongoing deleterious vulnerabilities in terms of employment, health, and housing. This article challenges this picture by focusing on the first Scottish new town which made space for working people's aspiration and new models of the self manifested in new lifestyles and social relations. Drawing on archival data and oral history interviews, we identify how elective relocation fostered and enabled new forms of identity predicated upon new housing, new social relations, and lifestyle opportunities focused on the family and home and elective social networks no longer determined by traditional class and gender expectations. These findings permit an intervention in the historical debates on post-war housing and social change which go beyond the materialistic experience to deeper and affective dimensions of the new town self.

    This paper evaluates the possibilities of using corn seed oil methyl ester as a fuel for compression ignition engines. The biodiesels are contained high oxygen content, and high Cetane number, due to this properties efficiency of biodiesel is higher than diesel fuel. The experiments were conducted with different biodiesel blends of (B10, B15, B20 and B25) corn seed oil on single cylinder four stroke natural aspirated diesel engines. Performance parameters and exhaust emissions are investigated in this experimental with the blends of the corn seed oil methyl ester and diesel fuel. The test results showed that the bio-diesel blends gives improved results for brake thermal efficiency and specific fuel consumption when compared with the diesel fuel. The emissions of corn seed methyl esters follow the same trend of diesel but the smoke opacity was reduces for all blends. From the investigation, corn seed methyl ester is also having the properties similar to diesel fuel; it is biodegradable and renewable fuel, so it will be used as an alternative for diesel fuel.

    We compared the clinical efficacy of surgical stabilization and internal pneumatic stabilization in severe flail chest patients who required prolonged ventilatory support. Thirty-seven consecutive severe flail chest patients who required mechanical ventilation were enrolled in this study. All the patients received identical respiratory management, including end-tracheal intubation, mechanical ventilation, continuous epidural anesthesia, analgesia, bronchoscopic aspiration, postural drainage, and pulmonary hygiene. At 5 days after injury, surgical stabilization with Judet struts (S group, n = 18) or internal pneumatic stabilization (I group, n = 19) was randomly assigned. Most respiratory management was identical between the two groups except the surgical procedure. Statistical analysis using two-way analysis of variance and Tukey's test was used to compare the groups. Age, sex, Injury Severity Score, chest Abbreviated Injury Score, number of rib fractures, severity of lung contusion, and Pao2/Fio2 ratio at admission were all equivalent in the two groups. The S group showed a shorter ventilatory period (10.8 +/- 3.4 days) than the I group (18.3 +/- 7.4 days) (p < 0.05), shorter intensive care unit stay (S group, 16.5 +/- 7.4 days; I group, 26.8 +/- 13.2 days; p < 0.05), and lower incidence of pneumonia (S group, 24%; I group, 77%; p < 0.05). Percent forced vital capacity was higher in the S group at 1 month and thereafter (p < 0.05). The percentage of patients who had returned to full-time employment at 6 months was significantly higher in the S group (11 of 18) than in the I group (1 of 19). This study proved that in severe flail chest patients, surgical stabilization using Judet struts has beneficial effects with respect to less ventilatory support, lower incidence of pneumonia, shorter trauma intensive care unit stay, and reduced medical cost than internal fixation. Moreover, surgical stabilization with Judet struts improved percent forced vital capacity from the

    Full Text Available Reconstruction of the eyelids after skin cancer excision can be challenging. Surgical treatment options are multiple; deep anatomy knowledge of lamellar components is mandatory to choose the most adequate surgical planning. Eyelids’ role in vision and social relationship is critical; both function and aesthetics are tough to restore. Using a flap provides a satisfying texture and colour match with adjacent tissues and ensures short contraction during healing; furthermore, grafts are sometimes necessary to achieve pleasing results. Hundreds of surgical techniques have been described aiming for eyelid reconstruction; in our paper, we want to provide for our audience the most reliable and useful procedures for subtotal and total eyelid reconstruction following NMSC full-thickness excision.

    To evaluate trends of emotional intelligence (EI) in surgical education and to compare the incorporation of EI in surgical education to other fields of graduate medical education. A MEDLINE search was performed for publications containing both "surgery" and "emotional intelligence" with at least one term present in the title. Articles were included if the authors deemed EI in surgical education to be a significant focus. A separate series of MEDLINE searches were performed with the phrase "emotional intelligence" in any field and either "surg*," "internal medicine," "pediatric," "neurology," "obstetric," "gynecology," "OBGYN," "emergency," or "psychiat*" in the title. Articles were included if they discussed resident education as the primary subject. Next, a qualitative analysis of the articles was performed, with important themes from each article noted. Lehigh Valley Health Network in Allentown, PA. Eight articles addressed surgical resident education and satisfied inclusion criteria with 0, 1, and 7 articles published between 2001 and 2005, 2005 and 2010, and 2010 and 2015, respectively. The comparative data for articles on EI and resident education showed the following : 8 in surgery, 2 in internal medicine, 2 in pediatrics, 0 in neurology, 0 in OBGYN, 1 in emergency medicine, and 3 in psychiatry. Integration of EI principles is a growing trend within surgical education. A prominent theme is quantitative assessment of EI in residents and residency applicants. Further study is warranted on the integration process of EI in surgical education and its effect on patient outcomes and long-term job satisfaction.

    propose an aspirational community theory of the firm (ACT) as a candidate theory by conceptualizing the firm as an aspirational community, the core of which is a group of like-minded people sharing similar or same aspiration/vision. To explain the existence of the firm, we make a distinction between......All of the three major theories of the firm, i.e., the transaction cost theory, knowledge-based theory and the entrepreneurship theory, offer some insightful analyses of the nature of the firm. However, they all have limitations and weaknesses in answering the fundamental question of the existence...... of the firm. In addition, they are all partial due to their particular focus on the multifaceted phenomenon of the firm. We argue that it is necessary and sufficient to develop a comprehensive yet integrative theory of the firm that combines the three competing yet complementary logics. Toward this end, we...

    Traditionally, aspiration with high negative pressure is recommended to obtain a specimen in transbronchial needle aspiration (TBNA). Undeniably, however, the assistant experiences difficulty in the generation of the negative pressure and precise control of the syringe while performing the procedure. To evaluate the effectiveness of the autoaspiration method created by our plunger lock in comparison with the conventional manual aspiration in the diagnosis of intrathoracic lymphadenopathy by TBNA. A prospective study was conducted on all patients referred for diagnostic TBNA of enlarged intrathoracic lymph nodes. Both automatic and manual aspiration techniques were performed after the needle had been completely inserted into the nodes. The diagnostic yield and the numbers of diagnostic cells or benign lymphoid cells obtained by each technique were compared in the same node. A total of 31 intrathoracic lymph nodes in 24 patients were prospectively studied. Twenty-four nodes (77.4%) were malignancies whereas 7 nodes (22.6%) were benign disease. Adequate lymph node samples were obtained in 30 targets (96.8%), and TBNA revealed definite diagnosis for 25 nodes (80.6%). Both aspiration techniques showed exactly the same diagnostic yield. However, the autoaspiration technique provided significantly more adequate samples than manual aspiration techniques did (P=0.003). The autoaspiration method using our plunger lock was superior to the manual method in obtaining the numbers of adequate samples in TBNA procedures.

    Objective: In this paper, we evaluate face, content and construct validity of the da Vinci Surgical Skills Simulator (dVSSS) across 3 surgical disciplines. Methods: In total, 48 participants from urology, gynecology and general surgery participated in the study as novices (0 robotic cases performed), intermediates (1–74) or experts (≥75). Each participant completed 9 tasks (Peg board level 2, match board level 2, needle targeting, ring and rail level 2, dots and needles level 1, suture sponge level 2, energy dissection level 1, ring walk level 3 and tubes). The Mimic Technologies software scored each task from 0 (worst) to 100 (best) using several predetermined metrics. Face and content validity were evaluated by a questionnaire administered after task completion. Wilcoxon test was used to perform pair wise comparisons. Results: The expert group comprised of 6 attending surgeons. The intermediate group included 4 attending surgeons, 3 fellows and 5 residents. The novices included 1 attending surgeon, 1 fellow, 13 residents, 13 medical students and 2 research assistants. The median number of robotic cases performed by experts and intermediates were 250 and 9, respectively. The median overall realistic score (face validity) was 8/10. Experts rated the usefulness of the simulator as a training tool for residents (content validity) as 8.5/10. For construct validity, experts outperformed novices in all 9 tasks (p < 0.05). Intermediates outperformed novices in 7 of 9 tasks (p < 0.05); there were no significant differences in the energy dissection and ring walk tasks. Finally, experts scored significantly better than intermediates in only 3 of 9 tasks (matchboard, dots and needles and energy dissection) (p < 0.05). Conclusions: This study confirms the face, content and construct validities of the dVSSS across urology, gynecology and general surgery. Larger sample size and more complex tasks are needed to further differentiate intermediates from experts. PMID:23914275

    Disordered swallowing, or dysphagia, is almost always present to some degree in people with Parkinson's disease (PD), either causing aspiration or greatly increasing the risk for aspiration during swallowing. This likely contributes to aspiration pneumonia, a leading cause of death in this patient population. Effective airway protection is dependent upon multiple behaviors, including cough and swallowing. Single voluntary cough function is disordered in people with PD and dysphagia. However, the appropriate response to aspirate material is more than one cough, or sequential cough. The goal of this study was to examine voluntary sequential coughing in people with PD, with and without dysphagia. Forty adults diagnosed with idiopathic PD produced two trials of sequential voluntary cough. The cough airflows were obtained using pneumotachograph and facemask and subsequently digitized and recorded. All participants received a modified barium swallow study as part of their clinical care, and the worst penetration-aspiration score observed was used to determine whether the patient had dysphagia. There were significant differences in the compression phase duration, peak expiratory flow rates, and amount of air expired of the sequential cough produced by participants with and without dysphagia. The presence of dysphagia in people with PD is associated with disordered cough function. Sequential cough, which is important in removing aspirate material from large- and smaller-diameter airways, is also impaired in people with PD and dysphagia compared with those without dysphagia. There may be common neuroanatomical substrates for cough and swallowing impairment in PD leading to the co-occurrence of these dysfunctions.

    Cytologic studies were done on fine needle aspirates of the lymph node and imprints of splenic biopsies from a patient with acute promyelocytic leukemia who was febrile while being treated with chemotherapy. Examination of the lymph node aspirates revealed pus and numerous pseudohyphae which were later identified as Candida tropicalis. When multiple nodular lesions were detected in the spleen by abdominal sonography and CT scan, needle biopsy of the spleen was done. Cytologic examination of touch imprints of the biopsy disclosed intracellular fungal blastospores. The patient was treated with and responded well to amphotericin B and 5-fluorocytosine. As a result of our experience with this patient we emphasize the importance of close incorporation of clinical information and diagnostic cytology. With such a cooperation, cytologic studies become a most useful method for diagnosis.

    Inhalation of foreign bodies, a leading cause of accidental death, is most common in preschool children. In this article we report our experience with a 5-year-old Greek girl who presented with a 24-hour history of sore throat, chest pain, and shortness of breath. Emergency bronchoscopy was performed and multiple small chewing gummi bear (HARIBO) particles impacted in the orifices of the right main bronchus and right lobar and segmentalinic bronchi were successfully removed and aspirated. Aspiration of gummi bears, which is for the first time reported, may cause a silent choking episode leading to life-threatening bronchi obstruction at multiple sites, even in children older than 4 years.

    Introduction Inflammation and pulmonary edema are involved in the pathogenesis of seawater aspiration-induced acute lung injury (ALI). Although several studies have reported that 1α,25-Dihydroxyvitamin D3 (calcitriol) suppresses inflammation, it has not been confirmed to be effective in seawater aspiration-induced ALI. Thus, we investigated the effect of calcitriol on seawater aspiration-induced ALI and explored the probable mechanism. Methods Male SD rats receiving different doses of calcitriol or not, underwent seawater instillation. Then lung samples were collected at 4 h for analysis. In addition, A549 cells and rat pulmonary microvascular endothelial cells (RPMVECs) were cultured with calcitriol or not and then stimulated with 25% seawater for 40 min. After these treatments, cells samples were collected for analysis. Results Results from real-time PCR showed that seawater stimulation up-regulated the expression of vitamin D receptor in lung tissues, A549 cells and RPMVECs. Seawater stimulation also activates NF-κB and RhoA/Rho kinase pathways. However, we found that pretreatment with calcitriol significantly inhibited the activation of NF-κB and RhoA/Rho kinase pathways. Meanwhile, treatment of calcitriol also improved lung histopathologic changes, reduced inflammation, lung edema and vascular leakage. Conclusions These results demonstrated that NF-κB and RhoA/Rho kinase pathways are critical in the development of lung inflammation and pulmonary edema and that treatment with calcitriol could ameliorate seawater aspiration-induced ALI, which was probably through the inhibition of NF-κB and RhoA/Rho kinase pathways.

    Full Text Available Massive aspiration of food is rare, but most common in people under the influence of alcohol or a drug and comatose patients who have impaired functioning of the central nervous system. The finding of small amounts of food material in the airway at autopsy does not indicate the true vital aspiration because of agonal or even early post-mortem overspills. Occlusion of the small airways, mainly the membranous and respiratory bronchioles, partial or total filling of bronchiolar lumen and the alveolar spaces with food or gastric content were typical morphologic findings. In our 10 year retrospective study we presented the data of 21 male and 4 female cases with a final diagnosis of fatal aspiration in age from 23 to 78 years (45.43±14.61 from the records of Morgue Specialization Department of the Council of Forensic Medicine. 13 cases found death at the scene without an eyewitness. All deaths were accidental in manner except one homicide. Toxicological analysis revealed blood alcohol concentration levels between 161 and 339 mg/dL in 7 cases. Morphine metabolites, benzodiazepine and barbituric acid derivatives, toluene and acetone were detected in 5 subjects. Aspirated materials were food in 14 cases, chewing gum in 3 cases, gastric content in 7 cases and a fabric gag in one case. The history, other evidence of external vomit on the clothing or immediate surroundings and toxicological analysis are by no means as significant as autopsy findings especially in cases of aspiration.

    To evaluate the effect of continuous aspiration of subglottic secretions (CASS) on the prevention of ventilator-associated pneumonia (VAP) in mechanically ventilated patients. Patients ventilated mechanically at the ICU from October, 2004 to April, 2006 were randomly divided into 2 groups: one group received CASS and the other did not (NASS group). CASS was performed immediately after admission for patients in the CASS group. The diagnosis of VAP was made based on clinical presentations, and the evaluation of VAP was done using simplified version of the clinical pulmonary infection score (CPIS). The general status of the patients, days of ventilated treatment, the volume of daily aspirated subglottic secretions, the morbidity and timing of VAP, days of stay in ICU and mortality within 28 days of hospitalization were recorded. One hundred and one patients were included in the study. There were 48 patients in the CASS group who were treated with mechanical ventilation more than 48 hours, and 43 patients in the NASS group. There was no significant difference in the general status of the patients and days of ventilation between 2 groups with the averaged score of APACHE II being 20.8 +/- 6.1. The average of CPIS was of 5.6 +/- 1.0 when VAP was diagnosed. The mean volume of aspirated subglottic secretions within the first 24 hours in the CASS group (n = 48) was (27.2 +/- 21.2) ml. The morbidity of VAP in the CASS and the NASS groups was 25.0% and 46.5% respectively (P = 0.032), and the length of time before the onset of VAP in these 2 groups was (7.3 +/- 4.2) days and (5.1 +/- 3.0) days respectively (P = 0.100). There was a significant increase in the percentage of gram-positive cocci from the lower respiratory tracts in the NASS group compared with that in the CASS group (P = 0.004). In the CASS group, the volume of the first daily aspirated subglottic secretions in patients with VAP was significantly less than that in patients without VAP (P = 0.006). The morbidity of

    To evaluate the effect of a self-controlled vocal exercise in elderly people with glottal closure insufficiency. Parallel-arm, individual randomized controlled trial. Patients who visited one of 10 medical centers under the National Hospital Organization group in Japan for the first time, aged 60 years or older, complaining of aspiration or hoarseness, and endoscopically confirmed to have glottal closure insufficiency owing to vocal cord atrophy, were enrolled in this study. They were randomly assigned to an intervention or a control group. The patients of the intervention group were given guidance and a DVD about a self-controlled vocal exercise. The maximum phonation time which is a measure of glottal closure was evaluated, and the number of patients who developed pneumonia during the six months was compared between the two groups. Of the 543 patients enrolled in this trial, 259 were allocated into the intervention group and 284 into the control; 60 of the intervention group and 75 of the control were not able to continue the trial. A total of 199 patients (age 73.9 ±7.25 years) in the intervention group and 209 (73.3 ±6.68 years) in the control completed the six-month trial. Intervention of the self-controlled vocal exercise extended the maximum phonation time significantly ( p < 0.001). There were two hospitalizations for pneumonia in the intervention group and 18 in the control group, representing a significant difference ( p < 0.001). The self-controlled vocal exercise allowed patients to achieve vocal cord adduction and improve glottal closure insufficiency, which reduced the rate of hospitalization for pneumonia significantly. gov Identifier-UMIN000015567.

    2011-04-01

    Middle ear surgery bears a high risk for injury of difficult to differentiate risk structures. Thus, a precise preparation in this area must be the surgical task. However, there are human (tremor) and systematic limitations (OR setup, narrow access). Assistance systems in terms of manipulators are so far not part of the clinical routine. Although, they could compensate for the above mentioned limitations. MANIPULATORS: This work reviews existing surgical manipulator systems. The expected value is an elevated patient safety through improving surgical accuracy and the reduction of ergonomic deficits. CLINICAL APPLICATION AND DEVELOPMENT: In clinical application there are simply modified industrial robots, highly complex master slave systems and small miniature master slave systems which are directly located at the patient. A disadvantage of most systems is the limited number of applicable instruments. Often, only especially designed instruments can be used. The goal in development should be to create a compact, short distance operated master slave system. The usability of standard (already available) instruments with an easy integration into the surgical and sterilisation procedure would lower the threshold for acceptance of such systems.The surgeon will remain the key player. He can only work efficiently in an ergonomic environment and will always have the responsibility for the intervention. From the authors perspective, highly automated systems should not be the research goal. © Georg Thieme Verlag KG Stuttgart · New York.

    Airway aspiration is a common problem in children with esophageal atresia (EA). Pediatric Eating Assessment Tool-10 (pEAT-10) is a self-administered questionnaire to evaluate dysphagia symptoms in children. A prospective study was performed to evaluate the validity of pEAT-10 to predict aspiration in children with EA. Patients with EA were evaluated for age, sex, type of atresia, presence of associated anomalies, type of esophageal repair, time of definitive treatment, and the beginning of oral feeding. Penetration-aspiration score (PAS) was evaluated with videofluoroscopy (VFS) and parents were surveyed for pEAT-10, dysphagia score (DS) and functional oral intake scale (FOIS). PAS scores greater than 7 were considered as risk of aspiration. EAT-10 values greater than 3 were assessed as abnormal. Higher DS scores shows dysphagia whereas higher FOIS shows better feeding abilities. Forty patients were included. Children with PAS greater than 7 were assessed as PAS+ group, and scores less than 7 were constituted as PAS- group. Demographic features and results of surgical treatments showed no difference between groups (p>0.05). The median values of PAS, pEAT-10 and DS scores were significantly higher in PAS+ group when compared to PAS- group (p<0.05). The sensitivity and specificity of pEAT-10 to predict aspiration were 88% and 77%, and the positive and negative predictive values were 22% and 11%, respectively. Type-C cases had better pEAT-10 and FOIS scores with respect to type-A cases, and both scores were statistically more reliable in primary repair than delayed repair (p<0.05). Among the postoperative complications, only leakage had impact on DS, pEAT-10, PAS and FOIS scores (p<0.05). The pEAT-10 is a valid, simple and reliable tool to predict aspiration in children. Patients with higher pEAT-10 scores should undergo detailed evaluation of deglutitive functions and assessment of risks of aspiration to improve safer feeding strategies. Level II (Development of

    To investigate whether drinking thin liquids with safety strategies increases the risk for pneumonia as compared with thickened liquids in patients who have demonstrated aspiration of thin liquids. Seven electronic databases, one clinical register, and three conference archives were searched. No language or publication date restrictions were imposed. Reference lists were scanned and authors and experts in the field were contacted. A blind review was performed by two reviewers for published or unpublished randomized controlled trials and prospective non-randomized trials comparing the incidence of pneumonia with intake of thin liquids plus safety strategies vs. thickened liquids in adult patients who aspirated on thin liquids. The data were extracted from included studies. Odds ratios (OR) for pneumonia were calculated from the extracted data. Risk of bias was also assessed with the included published trials. Seven studies out of 2465 studies including 650 patients met the inclusion criteria. All of the seven studies excluded patients with more than one known risk factor for pneumonia. Six studies compared thin water protocols to thickened liquids for pneumonia prevention. A meta-analysis was done on the six studies, showing no significant difference for pneumonia risk (OR = 0.82; 95% CI = 0.05-13.42; p = 0.89). There was no significant difference in the risk of pneumonia in aspirating patients who took thin liquids with safety strategies compared with those who took thickened liquids only. This result, however, is generalizable only for patients with low risk of pneumonia.

    Different surgical options are currently available for treating benign tumors of the parotid gland, and the discussion on optimal treatment continues despite several meta-analyses. These options include more limited resections (extracapsular dissection, partial lateral parotidectomy) versus more extensive and traditional options (lateral parotid lobectomy, total parotidectomy). Different schools favor one option or another based on their experience, skills and tradition. This review provides a critical analysis of the literature regarding these options. The main limitation of all the studies is the bias of selection for different surgical approaches. For this reason, we propose a staging system that could facilitate clinical decision making and the comparison of results. We propose four categories based on the size of the tumor and its location within the parotid gland. Category I includes tumors up to 3 cm, which are mobile, close to the outer surface and close to the parotid borders. Category II includes deeper tumors up to 3 cm. Category III comprises tumors greater than 3 cm involving two levels of the parotid gland, and category IV tumors are greater than 3 cm and involve more than 2 levels. For each category and for the various pathologic types, a guideline of surgical extent is proposed. The objective of this classification is to facilitate prospective multicentric studies on surgical techniques in the treatment of benign parotid tumors and to enable the comparison of results of different clinical studies.

    Full Text Available Objective To analyze surgical methods and evaluate treatment efficacy and safety for managing adrenal cystic lesions. Materials and methods All patients presenting with adrenal lesions of the West China Hospital were reviewed retrospectively from January 2003 to April 2013 and 47 were diagnosed as adrenal cysts. Basic information, clinical history, physical examination, laboratory investigations, abdominal ultrasound and enhanced computed tomography were detailed noted. Cysts with different surgical management were analyzed and surgery option operative time, postoperative complications and after-surgery hospital stay were all noted. The final diagnosis was judged by histopathology. Patients were followed from 3 month to 10 years. Results All the 47 patients with a mean age of 43.8 years were managed by surgical intervention. Compared laparoscopic technology with open technology, the laparoscopic has the advantage of a shorter operation time, shorter hospital stay after surgery and enhanced cosmesis. The histopathologic result was: 23 (50% were endothelial cysts and 16 (35% were pseudocysts. One patient had evidence to recurrence at the followed-up stage. Conclusion Adrenal cysts are rare and with the development of imaging techniques many of these are diagnosed incidentally. CT has advantages in detecting the cysts with haemorrhage, intracystic debris, calcification and mixed adrenal mass. Minimally invasive surgery offers equivalent efficacy to traditional open procedures, while providing a shorter operation time, shorter convalescence and improved cosmesis. Patients after surgical resection should be followed up closely especially if functional cysts and histopathology of cystic tumor are present.

    In many types of surgery, especially orthopedic procedures, power tools such as saws and drills are used. These tools can impart considerable energy in disrupting tissue and may produce aerosolized blood and material from bone and other tissues. Surgical lasers and electrocautery tools can also produce aerosols due to vaporization of blood and tissues. A number of studies have been reported concerning production of aerosols during surgery, and some of the aerosols produced may contain infectious materials. Health care workers have expressed concern and questions pertaining to the occupational transmission of blood-borne pathogens including the human immunodeficiency virus (HIV) and hepatitis B virus (HBV) via blood aerosols during surgery. Little or no data existed characterizing the aerosols produced performing surgical procedures. Because of this lack of data, the National Institute for Occupational Safety and Health funded a project at ITRI to assess the extent of aerosolization of blood and other tissues during surgical procedures in the laboratory and in a hospital surgical suite.

    Full Text Available BACKGROUND Textile industry workers face so many health-related challenges compared to the general population. Lymphadenopathy is one of the most common presenting symptoms of these people. This study is done in inhabitants of Tiruppur, a major textile industry area in the state of Tamil Nadu, India, where people work in garment factories for low wages. The aim of the study is to- 1. Evaluate the usefulness of Fine Needle Aspiration Cytology (FNAC as a diagnostic tool in cases of cervical lymphadenopathy. 2. Analyse the various cytomorphological presentations of tuberculous lymphadenopathy. MATERIALS AND METHODS In this study, a spectrum of lesions was diagnosed by fine needle aspiration of lymph nodes of 56 patients presenting with cervical lymphadenopathy. The diseases were categorised into suppurative lymphadenitis, granulomatous lymphadenitis, metastatic tumour deposits and lymphoproliferative disorder. Various morphological presentations of tuberculous lymphadenitis were also analysed. RESULTS From this study, it is observed that the most common diagnosis of cervical lymphadenopathy is reactive lymphadenitis (34%, followed by granulomatous lymphadenitis (30%. Also, among the tuberculosis cases, it is found that majority of cases had only granulomas (45% followed by caseous necrosis with granulomas (28%. CONCLUSION Knowing the usefulness of FNAC, it is concluded that it is a valuable, noninvasive, reliable and cost-effective technique in such a high-risk population. It also helps the clinician to start treatment based on FNAC findings and do the necessary at the earliest.

    Increasing data supports the role of bacterial inflammation in adverse events of cardiovascular and cerebrovascular diseases. In our previous research, DNA of bacterial species found in coronary artery thrombus aspirates and ruptured cerebral aneurysms were mostly of endodontic and periodontal origin, where Streptococcus mitis group DNA was the most common. We hypothesized that the genomes of S mitis group could be identified in thrombus aspirates of patients with lower limb arterial and deep venous thrombosis. Thrombus aspirates and control blood samples taken from 42 patients with acute or acute-on-chronic lower limb ischemia (Rutherford I-IIb) owing to arterial or graft thrombosis (n = 31) or lower limb deep venous thrombosis (n = 11) were examined using a quantitative real-time polymerase chain reaction to detect all possible bacterial DNA and DNA of S mitis group in particular. The samples were considered positive, if the amount of bacterial DNA in the thrombus aspirates was 2-fold or greater in comparison with control blood samples. In the positive samples the mean difference for the total bacterial DNA was 12.1-fold (median, 7.1), whereas the differences for S mitis group DNA were a mean of 29.1 and a median of 5.2-fold. Of the arterial thrombus aspirates, 57.9% were positive for bacterial DNA, whereas bacterial genomes were found in 75% of bypass graft thrombosis with 77.8% of the prosthetic grafts being positive. Of the deep vein thrombus aspirates, 45.5% contained bacterial genomes. Most (80%) of bacterial DNA-positive cases contained DNA from the S mitis group. Previous arterial interventions were significantly associated with the occurrence of S mitis group DNA (P = .049, Fisher's exact test). This is the first study to report the presence of bacterial DNA, predominantly of S mitis group origin, in the thrombus aspirates of surgical patients with lower limb arterial and deep venous thrombosis, suggesting their possible role in the pathogenesis of

    2013-01-01

    Tropical diabetic hand syndrome (TDHS) is an aggressive type of hand sepsis that results in significant morbidity and mortality among patients with diabetes in the tropics. This study set out to establish a protocol for the holistic management of TDHS to improve digit/hand salvage and function at AIC Kijabe Hospital. This prospective study examined the following demographics of patients presenting to the authors institution between October 2009 and September 2010 with TDHS: their sex, age, comorbidities, length of in-hospital stay, surgical and medical treatment, total cost of treatment, and immediate postdischarge outcomes. A total of 10 patients (3 men and 7 women) were presented with TDHS during the study period. Surgical procedures included a thorough debridement of the hand at initial presentation, followed by procedures aimed at preserving length and hand function, with digit or hand amputation when there was no possibility of salvage. Three hands were salvaged, without the need for an amputation; 2 of these, however, developed severe stiffness with resultant poor function. Fifty percent of the patients developed considerable disability; 3 of these patients had disabilities of the arm, shoulder, and hand, (DASH) scores of >90 at 6 months after treatment. TDHS appears to be more aggressive in some patients than in others; a multidisciplinary approach, with early involvement of the surgical team, and a radical surgical debridement are essential to improved outcomes. Although the goal of medical treatment (ie, glycemic control) is simple and easily achieved, surgical goals (salvage of limb or life, preservation of hand function) are more complex, costly, and difficult to achieve. Educating health care workers, diabetic patients, and their relatives on hand care is an important preventive measure. Diligence in taking antidiabetic medicine, early presentation, and appropriate care of TDHS are required for meaningful improvement in outcomes of patients with

    Full Text Available Abstract Background When encountering solid pancreatic lesions, nonpancreatic primary metastases are rare and differentiating a metastasis from a primary neoplastic lesion is challenging. The clinical presentation and radiologic features can be similar and the possibility of a pancreatic metastasis should be considered when the patient refers to a history of a different primary cancer. Endoscopic ultrasound offers a key anatomical advantage in accessing the pancreas and endoscopic ultrasound-guided fine-needle aspiration has become the gold standard method for diagnosing pancreatic lesions. Case presentation A 58-year-old white Hispanic woman with a history of uveal malignant melanoma, presented with abdominal pain and jaundice. On admission, laboratory tests were performed (her total bilirubin was 6.37 mg/dL with a direct fraction of 5.30 mg/dL. Cross-sectional, abdominal computed tomography with contrast, showed a low-attenuating lesion localized in the pancreatic head (measuring 4 × 3 cm and a thinner section of the distal bile duct suspicious for compression. Our patient was scheduled for an endoscopic ultrasound-guided fine-needle aspiration to establish a diagnosis. Endoscopic ultrasound showed a solid, hypoechoic, well-defined lesion with regular contours (measuring 3.17 × 2.61 cm, localized between the head and neck of the pancreas. Endoscopic ultrasound-guided fine-needle aspiration was performed with a 22G needle and cytology confirmed the diagnosis of metastatic melanoma. Our patient subsequently underwent right orbital exenteration, followed by duodenopancreatectomy without complications. At the moment our patient is receiving adjuvant chemotherapy at an outside oncology clinic. Conclusions To the best of our knowledge, this is a very rare presentation of an ocular malignant melanoma with an isolated pancreatic metastasis causing symptomatic biliary obstruction.

    Tetralogy of Fallot (TOF) is an index lesion for all paediatric and congenital heart surgeons. In designing an appropriate operation for children with TOF, the predicted postoperative physiology must be taken into account, both for the short and long term. A favourable balance between pulmonary stenosis (PS) and pulmonary insufficiency (PI) may be critical for preservation of biventricular function. A unified repair strategy to limit both residual PS and PI is presented, along with supportive experimental evidence.

    Gregory, M M

    1987-11-01

    Based on the preceding factors, a profile can be made for each light. The profile should include the following information: product literature with detailed information about the light, the average score from each of the six categories on the questionnaire, a summary of positive and negative comments from the questionnaire (recurring comments can identify significant factors), recommendations from other hospitals using the light, warranty and service information and any pertinent information about the vendor and manufacturer, information or comments from the clinical engineer, the purchasing agent, and the architect/engineer, and information about possible purchase agreements. Once the profiles of the lights are finished, present them to the OR committee or group charged with making the final decision. The information will enable the group to compare the lights and will serve as a basis for either the final purchase or a detailed bid specification. If cost is a major factor in the decision, the evaluation results can be used to justify purchasing lights that are more expensive but that the users believe are clearly superior. This constitutes the "professional justification" that some government institutions require to circumvent regulations that require buying the low-bid product. Although the result of this selection process is clearly a subjective decision, it is an informed subjective decision. Once the lights are installed, the staff members' satisfaction with the lights will not be based on objective criteria but on the same subjective opinions that were used to justify the selection.

    Despite limited data, the necessity for immediate surgical intervention in octogenarians with acute type A aortic dissection (AAD) has recently been questioned because the surgical risk may outweigh its potential benefits. At the same time, evolving stent graft technologies are pushing in the market for pathology within the ascending aorta, even for treatment of AAD. Against this background, we analyzed our institutional experience in this patient cohort during the last 8 years. Between October 2005 and October 2013, 39 patients aged older than 80 years (82 ± 2 years) underwent surgical repair for AAD, of which 29 patients (74%) were men. Owing to patient age and comorbidities, we aimed to limit the operation to supracoronary hemiarch replacement whenever possible. Clinical data were prospectively entered into our institutional database. Late follow-up was 3.6 ± 2.8 years and was 100% complete. Hemiarch replacement was performed in 32 patients (82%), and full arch replacement was necessary in the remaining 7. In 31 patients (79%), the aortic root could be glued and reconstructed or remained untouched. The remaining 8 patients (21%) underwent the bio-Bentall procedure. Mean ventilation time was 46 ± 23 hours, and the intensive care unit stay was 5 ± 9 days. We observed new postoperative permanent neurologic deficits in 2 patients (5%) and transient neurologic deficits in 3 (8%). The 30-day mortality was 26% (n = 10). Kaplan-Meier estimates for late survival were 46% ± 16% at 5 years. Given the guidelines regarding the predicted risk of death in patients with untreated AAD, current data suggest a survival benefit with immediate open surgical intervention even in octogenarians. Similarly to the early days of transcatheter-based aortic valve implantation, open surgical reference data are warranted to set the bar for upcoming endovascular treatment of AAD in octogenarians.

    Full Text Available INTRODUCTION: To assess whether the value of CYFRA21-1 in the aspirates of ultrasonography-guided fine-needle aspiration biopsy (US-FNAB can contribute to improving the performances of US-FNAB in the diagnosis of axillary lymph node (LN metastasis in breast cancer patients. METHODS: US-FNAB was performed in 156 axillary LNs in 152 breast cancer patients (mean age: 51.4 years, range: 17-92 years. Concentrations of CYFRA21-1 were measured from washouts of the syringe used during US-FNAB. Tumor marker concentrations, US-FNAB, intraoperative sentinel node biopsy (SNB, and surgical pathology results were reviewed and analyzed. For comparison, the values of CEA and CA15-3 were also measured from washouts. RESULTS: Among the 156 LNs, 75 (48.1% were benign, and 81 (51.9% were metastases. Mean concentrations of CYFRA21-1 were significantly higher in metastasis compared to benign LNs (P<0.001. US-FNAB combined to CYFRA21-1 showed significantly higher sensitivity, NPV, and accuracy compared to US-FNAB alone (all values P<0.05. All diagnostic indices of US-FNAB combined to CYFRA21-1 were significantly higher compared to US-FNAB combined with CEA or CA15-3 (all P<0.001. Of the 28 metastatic LNs which showed metastasis on SNB, CYFRA21-1 showed higher positive rate of 75.0% (CEA or CA15-3∶60.7%, P = 0.076. CONCLUSION: Measuring CYFRA 21-1 concentrations from US-FNAB aspirates improves sensitivity, NPV, and accuracy of US-FNAB alone, and may contribute to reducing up to 75.0% of unnecessary intraoperative SNB. Compared to CEA or CA15-3, CYFRA21-1 shows significantly higher performances when combined to US-FNAB in the preoperative diagnosis of LN metastasis in breast cancer patients.

    Full Text Available Open reduction and anatomic reduction can create better function for the temporomandibularjoint, compared with closed treatment in mandible fracture surgery. Therefore, the doubleminiplate fixation technique via mini-retromandibular incision was used in order to makethe most stable fixation when performing subcondylar fracture surgery. Those approachesprovide good visualization of the subcondyle from the posterior edge of the ramus, allow thesurgeon to work perpendicularly to the fracture, and enable direct fracture management.Understanding the biomechanical load in the fixation of subcondylar fractures is alsonecessary in order to optimize fixation methods. Therefore, we measured the biomechanicalloads of four different plate fixation techniques in the experimental model regardingmandibular subcondylar fractures. It was found that the loads measured in the two-platefixation group with one dynamic compression plate (DCP and one adaption plate showed thehighest deformation and failure loads among the four fixation groups. The loads measuredin the one DCP plate fixation group showed higher deformation and failure loads than theloads measured in the two adaption plate fixation group. Therefore, we conclude that theselection of the high profile plate (DCP is also important in order to create a stable load in thesubcondylar fracture.

    To describe the clinical findings, diagnosis, and treatment of an incomplete cleft of the 5th-8th sternebra and a cranioventral abdominal wall hernia in a 2 month old Ragdoll kitten and to evaluate the short- and long-term outcome. Clinical report. Ragdoll cat (n = 1), 2 months old. Sternal cleft was confirmed by thoracic radiographs. Computed tomography (CT) was used to plan an optimal surgical approach. A ventral median incision was made, starting at the 3rd sternebra and extended into the abdomen. Ostectomy of the proximal part of the 5th left sternebra was performed. Lateral periosteal flaps were created, unfolded, and absorbable monofilament sutures preplaced to facilitate closure and the repair was reinforced by 2 peristernal sutures. A bone graft was applied, and the free margin of the omentum was sutured to the cranial aspect of the wound. No major complications occurred. At 3 weeks, CT scan confirmed approximation of the hemisternebrae and at 10 months, complete fusion of the hemisternebrae had not occurred, but a strong connection of the sternal bars was present. Sternal cleft is a rare congenital abnormality that can be corrected surgically with favorable outcome. © Copyright 2014 by The American College of Veterinary Surgeons.
