    Twelve adults with maxillary width discrepancy of greater than 5 mm were treated by surgically assisted rapid maxillary expansion. The procedure consisted of bilateral zygomatic buttress and midpalatal osteotomies combined with the use of a tooth-borne orthopedic device postoperatively. Mean palatal expansion of 7.5 mm (range of 6 to 13 mm), measured in the first molar region, was achieved within 3 weeks in all patients. Expansion remained stable during the 12-month study period, with a mean relapse for the entire group of 0.88 +/- 0.48 mm. Morbidity was limited to mild postoperative discomfort. The results of this preliminary study indicated that surgically assisted rapid maxillary expansion is a safe, simple, and reliable procedure for achieving a permanent increase in skeletal maxillary width in adults. Further study is necessary to document the three-dimensional movements of the maxillary segments and long-term stability of the skeletal and dental changes. PMID:1453038

    A major challenge in the era of shared medical decision making is the navigation of complex relationships between the physicians, patients, and surrogates who guide treatment plans for critically ill patients. This review of ethical issues in adult surgical critical care explores factors influencing interactions among the characters most prominently involved in health care decisions in the surgical intensive care unit: the patient, the surrogate, the surgeon, and the intensivist. Ethical tensions in the surgeon-patient relationship in the elective setting may arise from the preoperative surgical covenant and the development of surgical complications. Unlike that of the surgeon, the intensivist's relationship with the individual patient must be balanced with the need to serve other acutely ill patients. Due to their unique perspectives, surgeons and intensivists may disagree about decisions to pursue life-sustaining therapies for critically ill postoperative patients. Finally, although surrogates are asked to make decisions for patients on the basis of the substituted judgment or best interest standards, these models may underestimate the nuances of postoperative surrogate decision making. Strategies to minimize conflicts regarding treatment decisions are centered on early, honest, and consistent communication between all parties. PMID:25990272

    Coarctation of the aorta (CoA), a juxtaductal obstructive lesion in the descending aorta and commonly associated with hypoplasia of the aortic arch occurs in 5-8% of patients with congenital heart disease. Since the initial surgical corrections in the 1950, surgical and transcatheter options have constantly evolved. Nowadays, transcatheter options are widely accepted as the initial treatment of choice in adults presenting with native or recurrent CoA. Surgical techniques are mainly reserved for patients with complex aortic arch anatomy such as extended arch hypoplasia or stenosis or para-CoA aneurysm formation. Extended aneurysms can be covered by conformable stents but stent implantation may require preparative vascular surgery. Complex re-CoA my best be treated by an ascending to descending bypass conduit. The following review aims to describe current endovascular and surgical practice pointing out modern developments and their limitations. PMID:27243624

    If nonoperative measures are unsuccessful in managing the pain and disability of adult spinal deformities, surgical correction may provide the potential for significant improvement in a patient's quality of life. However, these procedures have a relatively high risk of complications. Identifying patients that may benefit from surgical intervention requires a thorough understanding of potential complications and managing the risks of any individual patient. Complications do not necessarily result in poor outcomes, and good outcomes are not always complication free. Higher risk patients potentially have more to gain, even if they experience complications. With the rapidly expanding senior population and expanded capabilities to manage high-risk patients, it is helpful to consider the lessons provided by ever expanding databases of outcome measures to refine the surgical decision-making process.

    The experience of critical care is stressful for both patients and their families. This is especially true when patients are not able to make their own care decisions. This article details the creation of a Family Experience Survey in a surgical intensive care unit (SICU) to capture and improve overall experience. Kolcaba's "Enhanced Comfort Theory" provided the theoretical basis for question formation, specifically in regards to the four aspects of comfort: "physical," "psycho-spiritual," "sociocultural" and "environmental." Survey results were analyzed in real-time to identify and implement interventions needed for issues raised. Overall, there was a high level of satisfaction reported especially with quality of care provided to patients, communication and availability of nurses and doctors, explanations from staff, inclusion in decision making, the needs of patients being met, quality of care provided to patients and cleanliness of the unit. It was noted that 'N/A' was indicated for cultural needs and spiritual needs, a chaplain now rounds on all patients daily to ensure these services are more consistently offered. In addition, protocols for doctor communication with families, palliative care consults, daily bleach cleaning of high touch areas in patient rooms and nurse-led progressive mobility have been implemented. Enhanced comfort theory enabled the opportunity to identify and provide a more 'broad' approach to care for patients and families. PMID:26608426

    Objective: To introduce a novel surgical technique for correction of adult congenital webbed penis. Methods: From March 2010 to December 2011, 12 patients (age range: 14–23 years old) were diagnosed as having a webbed penis and underwent a new surgical procedure designed by us. Results: All cases were treated successfully without severe complication. The operation time ranged from 20 min to 1 h. The average bleeding volume was less than 50 ml. All patients achieved satisfactory cosmetic results after surgery. The penile curvature disappeared in all cases and all patients remained well after 1 to 3 months of follow-up. Conclusions: Adult webbed penis with complaints of discomfort or psychological pressure due to a poor profile should be indicators for surgery. Good corrective surgery should expose the glans and coronal sulcus, match the penile skin length to the penile shaft length dorsally and ventrally, and provide a normal penoscrotal junction. Our new technique is a safe and effective method for the correction of adult webbed penis, which produces satisfactory results. PMID:22949367

    Introduction and Aim: The management of posterior fossa arachnoid cyst (PFAC) in adults is controversial. To review our cases and literature, propose a practically useful surgical strategy, which gives excellent long-term outcome in management of PFAC. Materials and Methods: We analyzed our case records of 26 large intracranial arachnoid cysts in adults treated over 12 years. Of them, we had 7 patients with symptomatic PFAC. Reviewed the literature of 174 PFAC cases (1973–2012) and added 7 of our new cases with a follow-up ranging from 3 to 12 years. Results: In 6 cases the PFAC was located in the midline. In the 7th case, it was located laterally in the cerebello-pontine (CP) angle. All patients were treated surgically. Excision of the cyst was performed in 5 of these cases. Among the two intra-fourth ventricular cysts, in both the cases cysto-peritoneal shunt was performed. Postoperative computed tomography/magnetic resonance imaging showed variable decrease in size of the cyst even though clinically all patients improved. We propose a surgical strategy for the management of these cases which would aid the surgeon in decision making. Discussion: We observed that these PFACs can occur either in the midline within the fourth ventricle or retroclival region or extra-fourth ventricular region. It can also develop laterally in the CP angle or behind the cerebellum or as intracerebellar cyst. Importance of this is except for Midline Intra-fourth ventricular cyst/retroclival cyst, the rest all can be safely excised with excellent long term outcome. The treatment strategy for Midline Intra-fourth ventricular cyst/retroclival cyst can be either cysto-peritoneal shunt or endoscopic fenestration of the cyst. PMID:25767579

    The role of operative intervention for hereditary pancreatitis, a rare form of chronic parenchymal destruction, is unclear. To determine whether surgical therapy is safe and provides prolonged symptomatic relief, the authors reviewed the management of 22 adults (11 men, 11 women) with hereditary pancreatitis treated surgically between 1950 and 1989. Hereditary pancreatitis was defined as a family history of two or more relatives with pancreatitis and clinical, biochemical, or radiologic evidence of pancreatitis. The mean ages at onset of symptoms and at operation were 15 years (range, 3 to 52 years) and 31 years (range, 18 to 54 years), respectively. Pain was the primary indication for operation in all patients. Additional symptoms included nausea, vomiting (73%), weight loss (55%), and diarrhea (41%). Ductal dilatation was present in 68%, pancreatic parenchymal calcifications in 73%, pseudocysts in 36%, and splenic vein thrombosis in 18%. Primary operations included ductal drainage in 10 patients, pancreatic resection alone in three, resection with drainage in three, cholecystectomy plus sphincteroplasty in two, cholecystectomy with or without common bile duct exploration in two, pancreatic abscess drainage in one, and pseudocyst drainage in one. There were no perioperative deaths, and the morbidity rate was 14% (intra-abdominal abscess, wound infection, and urinary tract infection). Symptoms recurred in nine patients. Severity prompted reoperation in five. Secondary operations included pancreatic resection in three, pseudocyst excision in one, and pancreaticolithotomy in one. Follow-up to date is complete and extends for a median of 85 months. Eighteen patients (82%) are clinically improved or asymptomatic. Symptoms have persisted in four patients, and two patients have died of pancreatic carcinoma. Two patients died of unrelated causes. Surgical therapy for patients with hereditary pancreatitis selected on the basis of the traditional indications for surgical

    Intestinal non-rotation has been recognized as a cause of obstruction in neonates and children. It is very rarely seen in the adult and assumes surgical significance owing to the potential risk of midgut or ileocecal volvulus. However, it can also cause significant intermittent abdominal pain in the adult. We describe six personally observed patients with this malformation and analyze 38 case reports published in the English and German literature since 1923. We establish that in the acute symptomatic form only emergency laparotomy can provide the correct diagnosis and decrease the risk of bowel disturbance. In the chronic forms, barium studies of the whole intestinal tract reveal varying degrees of midgut malrotation and the non-rotation is confirmed in each case. Also in these forms, exploratory laparotomy with a consequent staging of the abdominal situs is to be recommended. In the operation described by Ladd the ascending colon is sutured at the colon descendens and sigmoideum. After this procedure the mesenterial pedicle is fixed and the risk of midgut torsion remains minimal. All reported cases after surgery are symptom-free. PMID:1857952

  10. Intravenous fish oil in adult intensive care unit patients.

    Omega-3 fatty acids contained in fish oils have shown efficacy in the treatment of chronic and acute inflammatory diseases due to their pleiotropic effects on inflammatory cell signalling pathways. In a variety of experimental and clinical studies, omega-3 fatty acids attenuated hyperinflammatory conditions and induced faster recovery. This chapter will shed light on the effects of intravenous fish oil in adult intensive care unit (ICU) patients and will discuss clinical data and recent meta-analyses on the topic. While significant beneficial effects on infection rates and the lengths of ICU and hospital stays have concordantly been identified in three recent meta-analyses on non-ICU surgical patients, the level of evidence is not so clear for critically ill patients. Three meta-analyses published in 2012 or 2013 explored data on the ICU population. Although the present data suggest the consideration of enteral nutrition enriched with fish oil, borage oil and antioxidants in mild to severe acute respiratory distress syndrome, only one of the three meta-analyses found a trend (p = 0.08) of lower mortality in ICU patients receiving intravenous omega-3 fatty acids. Two of the meta-analyses indicated a significantly shorter hospital stay (5.17-9.49 days), and one meta-analysis found a significant reduction in ICU days (1.92). As a result of these effects, cost savings were postulated. Unlike in surgical patients, the effects of fish oil on infection rates were not found to be statistically significant in ICU patients, and dose-effect relationships were not established for any cohort. Thus, obvious positive secondary outcome effects with intravenous fish oil have not yet been shown to transfer to lower mortality in critically ill patients. There is a need for adequately powered, well-planned and well-conducted randomized trials to give clear recommendations on the individual utility and dosage of intravenous omega-3 fatty acids in critical illness.

    Update on pathologies of adult spinal deformity (ASD): With advancement of aging society, ASD has become one of the most notable topics of spinal disorders owing to its significant impact on health related quality of life. Treatment for ASD is challenging due to complex nature of deformity and high prevalence of comorbidities. Spino-pelvic harmony that is evaluated by pelvic incidence (PI) minus lumbar lordosis (LL) is the most important concept, which allows us to understand pathology of ASD more deeply. Proposed optimum "PI minus LL" is within ±10°. However, according to analysis of patients having good surgical outcomes, minimum requirement of postoperative "PI minus LL" is calculated by following equation: "PI minus LL" = 0.41PI - 11.12 (r = 0.45, p = 0.0059). "PI minus LL" is not fixed but flexible value reflecting the specific setting of the individual PI. To date, little is known about dynamic global sagittal alignment that is susceptible to compensatory mechanisms. Gait analysis revealed that compensated sagittal balance by pelvic retroversion in static standing was lost immediately after walking due to alignment change of the pelvis and worsened over time. Dynamic assessment of sagittal balance is recommended. Update on surgical strategies for ASD: We classified ASD into following 5 types in terms of curve patterns, global balance, and curve flexibility: Type 1, well-balanced scoliosis with flexible kyphosis is indicated for corrective posterior spinal fusion (PSF) without any release procedures; Type 2, poor-balanced scoliosis with flexible kyphosis is well corrected by aggressive intervertebral release with PSF; Type 3, fixed sagittal imbalance without coronal deformity is candidate for pedicle subtraction osteotomy; Type 4, fixed sagittal imbalance with coronal deformity is indicated for vertebral column resection; and Type 5, severe scoliosis without marked global sagittal malalignment can be treated by corrective anterior spinal fusion

    The aims of this study were to test the hypotheses that the type of 3rd molar removal determines baseline pain and that baseline pain influences analgesic assay sensitivity. Three groups of patients were studied: (i) 100 patients that had one fully erupted maxillary 3rd molar extracted; (ii) 95 patients that had one lower impacted 3rd molar surgically removed; and (iii) 98 patients that had two ipsilateral impacted 3rd molars surgically removed. In a randomized, double-blind fashion, the patients received (every third hour, three times) either: (i) paracetamol 1g; (ii) paracetamol 1g plus codeine 60 mg; or (iii) placebo. Baseline pain intensity (100 mm Visual Analogue Scale) was significantly lower after extraction (8 mm (2-20)) (=median (25th -75th percentile) than after surgical removal of one 3rd molar (35 mm (15-57)), which was significantly lower than pain intensity after surgical removal of two 3rd molars (49 mm (24-82)). Analgesic effects of the active test drugs were superior to placebo. Paracetamol with and without codeine could be distinguished in patients after surgical removal of one 3rd molar. In conclusion, baseline pain was related to the degree of surgical trauma, but large inter-individual variation in baseline pain intensity reduced the ability to distinguish between paracetamol with and without codeine.

    BACKGROUND Sickle cell disease patients are more likely than the general population to undergo surgery and usually do so at a younger age. Female sickle cell disease patients also have special gynecological and obstetric issues related to their disease. METHODS We collected data through standardized clinical report forms, patient interviews, and medical records from 509 adult sickle cell disease patients. Logistic regression was used to estimate the association between multiple variables and each of the surgery types. We also determined the prevalence and outcomes of pregnancy in 284 women with sickle cell disease in this population. RESULTS Almost 50% of patients aged 18–27 years had had a cholecystectomy. Mean corpuscular hemoglobin, total bilirubin, and lactate dehydrogenase were significantly higher in the postcholecystectomy group; 9.5% of 504 individuals had undergone splenectomy. Hematocrit, body mass index, and red blood cell count were significantly higher in the postsplenectomy group. Hip replacement had been performed in 9.2% of individuals, with the prevalence increasing as early as the fourth decade and continuing to increase through the sixth decade of life. A history of pregnancy was present in 190 women (67%). Of 410 pregnancies, only 53.9% resulted in live births, 16.6% were voluntarily terminated, and 29.5% were complicated by miscarriage, still birth, or ectopic implantation. CONCLUSIONS Sickle cell disease continues to have a strong effect on the mean age for common surgeries and impacts pregnancy outcomes. We conclude that this population has a unique surgical and obstetric history that should be further studied to provide insight into potentially more effective preventive approaches to end-organ damage.

    Surgical intensive care unit (ICU) stay of longer than 10 days is often described by the experienced intensivist as a "complicated clinical course" and is frequently attributed to persistent immune dysfunction. "Systemic inflammatory response syndrome" (SIRS) followed by "compensatory anti-inflammatory response syndrome" (CARS) is a conceptual framework to explain the immunologic trajectory that ICU patients with severe sepsis, trauma, or emergency surgery for abdominal infection often traverse, but the causes, mechanisms, and reasons for persistent immune dysfunction remain unexplained. Often involving multiple-organ failure (MOF) and death, improvements in surgical intensive care have altered its incidence, phenotype, and frequency and have increased the number of patients who survive initial sepsis or surgical events and progress to a persistent inflammation, immunosuppression, and catabolism syndrome (PICS). Often observed, but rarely reversible, these patients may survive to transfer to a long-term care facility only to return to the ICU, but rarely to self-sufficiency. We propose that PICS is the dominant pathophysiology and phenotype that has replaced late MOF and prolongs surgical ICU stay, usually with poor outcome. This review details the evolving epidemiology of MOF, the clinical presentation of PICS, and our understanding of how persistent inflammation and immunosuppression define the pathobiology of prolonged intensive care. Therapy for PICS will involve innovative interventions for immune system rebalance and nutritional support to regain physical function and well-being. PMID:22695412

    Study Design Cross-sectional study with prospective recruitment Objective To determine the relationship of pain intensity (back and leg) on patients’ acceptance of surgical complication risks when deciding whether or not to undergo lumbar spinal fusion. Background To formulate informed decisions regarding lumbar fusion surgery, preoperative discussions should include a review of the risk of complications balanced with the likelihood of symptom relief. Pain intensity has the potential to influence a patient’s decision to consent to lumbar fusion. We hypothesized that pain intensity is associated with a patient’s acceptance of surgical complication risks. Methods Patients being seen for the first time by a spine surgeon for treatment of a non-traumatic or non-neoplastic spinal disorder completed a structured questionnaire. It posed 24 scenarios, each presenting a combination of risks of 3 complications (nerve damage, wound infection, nonunion) and probabilities of symptom relief. For each scenario, the patient indicated whether he/she would/would not consent to a fusion for low back pain (LBP). The sum of the scenarios in which the patient responded that he or she would elect surgery was calculated to represent acceptance of surgical complication risks. A variety of other data were also recorded, including age, gender, education level, race, history of non-spinal surgery, duration of pain, and history of spinal injections. Data were analyzed using bivariate analyses and multivariate regression analyses. Results The mean number of scenarios accepted by 118 enrolled subjects was 10.2 (median 8, standard deviation 8.5, range 0 to 24, or 42.5% of scenarios). In general, subjects were more likely to accept scenarios with lower risks and higher efficacy. Spearman’s rank correlation estimates demonstrated a moderate association between the LBP intensity and acceptance of surgical complication risks (r=0.37, p=0.0001) while leg pain intensity had a weak but positive

    Purpose To determine the role age plays in use of intensive care for patients who have major surgery. Materials and Methods Retrospective cohort study examining the association between age and admission to an intensive care unit (ICU) for all Medicare beneficiaries aged 65 or older who had a hospitalization for one of five surgical procedures: esophagectomy, cystectomy, pancreaticoduodenectomy (PD), elective open abdominal aortic aneurysm repair (open AAA), and elective endovascular AAA repair (endo AAA) from 2004–08. The primary outcome was admission to an ICU. Secondary outcomes were complications and hospital mortality. We used multi-level mixed-effects logistic regression to adjust for other patient and hospital-level factors associated with each outcome. Results The percentage of hospitalized patients admitted to ICU ranged from 41.3% for endo AAA to 81.5% for open AAA. In-hospital mortality also varied, from 1.1% for endo AAA to 6.8% for esophagectomy. After adjusting for other factors, age was associated with admission to ICU for cystectomy (Adjusted Odds Ratio (AOR) 1.56 (95% CI 1.36–1.78) for age 80–84+; 2.25 (1.85–2.75) age 85+ compared with age 65–69), PD (AOR 1.26 (1.06–1.50) age 80–84; 1.49 (1.11–1.99) age 85+) and esophagectomy (AOR 1.26 (1.02–1.55) age 80–84; 1.28 (0.91–1.80) age 85+). Age was not associated with use of intensive care for open or endo AAA. Older age was associated with increases in complication rates and in-hospital mortality for all five surgical procedures. Conclusions The association between age and use of intensive care was procedure-specific. Complication rates and in-hospital mortality increased with age for all five surgical procedures.

    Muscle weakness is common in the surgical intensive care unit (ICU). Low muscle mass at ICU admission is a significant predictor of adverse outcomes. The consequences of ICU-acquired muscle weakness depend on the underlying mechanism. Temporary drug-induced weakness when properly managed may not affect outcome. Severe perioperative acquired weakness that is associated with adverse outcomes (prolonged mechanical ventilation, increases in ICU length of stay, and mortality) occurs with persistent (time frame: days) activation of protein degradation pathways, decreases in the drive to the skeletal muscle, and impaired muscular homeostasis. ICU-acquired muscle weakness can be prevented by early treatment of the underlying disease, goal-directed therapy, restrictive use of immobilizing medications, optimal nutrition, activating ventilatory modes, early rehabilitation, and preventive drug therapy. In this article, the authors review the nosology, epidemiology, diagnosis, and prevention of ICU-acquired weakness in surgical ICU patients. PMID:26445385

    Little is known about the circumstances under which older adults initiate chronic dialysis and subsequent outcomes. Using national registry data, we conducted a retrospective analysis of 416,657 Medicare beneficiaries aged ≥67 years who initiated chronic dialysis between January 1995 and December 2008. Our goal was to define the relationship between health care intensity around the time of dialysis initiation and subsequent survival and patterns of hospitalization, use of intensive procedures (mechanical ventilation, feeding tube placement, and cardiopulmonary resuscitation), and discontinuation of dialysis before death. We found that most patients (64.5%) initiated dialysis in the hospital, including 36.6% who were hospitalized for ≥2 weeks and 7.4% who underwent one or more intensive procedures. Compared with patients who initiated dialysis in the outpatient setting, those who received the highest intensity of care at dialysis initiation (those hospitalized ≥2 weeks and receiving at least one intensive procedure) had a shorter median survival (0.7 versus 2.1 years; P<0.001), spent a greater percentage of remaining follow-up time in the hospital (median, 22.9% versus 3.1%; P<0.001), were more likely to undergo subsequent intensive procedures (44.9% versus 26.0%; adjusted hazard ratio, 2.33; 95% confidence interval [CI], 2.27 to 2.39), and were less likely to have discontinued dialysis before death (19.1% versus 26.2%; adjusted odds ratio, 0.68; 95% CI, 0.65 to 0.72). In conclusion, most older adults initiate chronic dialysis in the hospital. Those who have a prolonged hospital stay and receive other forms of life support around the time of dialysis initiation have limited survival and more intensive patterns of subsequent healthcare utilization.

    With the six QSEN competencies woven throughout the baccalaureate nursing curriculum, which includes high-fidelity simulation, the aim of this research was to uncover deficits in QSEN-related clinical opportunities. Pre-licensure BSN nursing students enrolled in a sophomore-level medical-surgical rotation augmented with 25 percent simulation were observed directly, with time-on-task for each QSEN competency recorded and tabulated. The students were found to spend little time addressing several of the six competency areas in both clinical and simulation settings. Fully integrated classroom, simulation, and clinical experiences need to be considered in an effort to offer a full spectrum of QSEN-based knowledge and skill theory and practice for pre-licensure nursing students.

    Introduction: Intensive care units (ICUs) are associated with a greater risk of developing nosocomial infections (NIs) than other departments. Aim: The aim of this study was to determine the rate, the site and causative organisms of NIs in the surgical ICU at University Clinical Center Tuzla. Methods: All patients admitted to the surgical ICU were followed prospectively, for the development of NIs (January-December 2010). Determination of NIs was performed using standardized the Centers for Disease Control and Prevention (CDC) criteria. Results: 94 out of 834 patients (11.27%) developed NIs. Respiratory tract infections were seen in 56 (60%), urinary tract infections in 15 (16%) and gastrointestinal tract infections in 8 (9%) patients. Other infections identified were surgical site, bloodstream and skin infections. Gram-negative organisms were reported in approximately 75% of cases (78.7% extended-spectrum beta-lactamase (ESBL)-producers). Klebsiella pneumoniae was the commonest (51.0%), followed by Proteus mirabilis (21.3%) and Pseudomonas aeruginosa (10.6%). Methicillin-resistant Staphylococcus aureus (MRSA) (16%), and Clostridium difficile (9.6%) were the commonest among gram-positive bacteria. Conclusion: Respiratory and urinary tract infections made up the great majority of NIs. ICU patients are more susceptible to NIs, emphasizing the importance of continuous surveillance and enforcement of specific infection control measures. PMID:24757393

The data were reviewed regarding the demographics, time of presentation, place of reference, Acute Physiology and Chronic Health Evaluation II (APACHE II) score and Injury Severity Score (ISS), surgical procedures, complications, length of stay and mortality. Results: A total of 80 wounded patients (70 males and 10 females) with a mean age of 28.7 years were admitted to surgical ICUs. The most frequent cause of injury was gunshot injury. The mean time interval between the occurrence of injury and time of admission was 2.87 days. Mean ISS score on admission was 21, and mean APACHE II score was 15.7. APACHE II scores of non-survivors were significantly increased compared with those of survivors (P=0.001). No significant differences was found in the age, ISS, time interval before admission, length of stay in ICU, rate of surgery before or after admission. Conclusion: The most important factor affecting mortality in this particular trauma-ICU patient population from Syrian civil war was the physiological condition of patients on admission. Rapid transport and effective initial and on-road resuscitation are critical in decreasing the mortality rate in civil wars and military conflicts. PMID:27375683

    Abstract: Preoperative anemia and nadir hemoglobin (Hb) during cardiopulmonary bypass (CPB) have been identified as significant risk factors for blood transfusion during cardiac surgery. The aim of this study was to confirm the association between preoperative anemia, perioperative fluid management, and blood transfusion. In addition, the proportion of elective cardiac surgery patients presenting for surgery with anemia was identified to examine whether the opportunity exists for timely diagnosis and intervention. Data from referral until hospital discharge were comprehensively reviewed over a 12-month period for all nonemergency cardiac surgical patients operated on in our institution. Of the 342 patients identified, elective cases were referred a median of 35 days before preoperative clinic and operated on a median of 14 days subsequently. Subacute cases had a median of 3 days from referral to surgery. As per the World Health Organization (WHO) criteria for anemia, 24.2% of elective and 29.6% of subacute patients were anemic. Blood transfusion was administered to 46.2% of patients during their admission. Transfusion was more likely in patients who were female (odds ratio [OR]: 2.45, 95%confidence interval [CI]: 1.28–4.70), had a low body mass index (BMI) (OR: .89, 95% CI: .84–.94), preoperative anemia (OR: 5.15, 95% CI: 2.59–10.24), or renal impairment (OR: 5.44, 95% CI: 2.42–12.22). Hemodilution minimization strategies reduced the Hb fall during CPB, but not transfusion rates. This study identifies a high prevalence of preoperative anemia with sufficient time for elective referrals to undergo appropriate diagnosis and interventions. It also confirms that low red cell mass (anemia and low BMI) and renal impairment are predictors of perioperative blood transfusion. Perfusion strategies to reduce hemodilution are effective at minimizing the intraoperative fall in Hb concentration but did not influence transfusion rate. PMID:26543251

  7. Surgical versus conservative management of adult intussusception: Case series and review

    2016-01-01

    Introduction Intussusception is the telescoping of a segment of bowel into its adjacent segment. It is a known cause of abdominal pain in the pediatric population, however, it is rare in the adult. Adults do not always present with the typical symptoms seen in young children, making the clinical diagnosis more difficult. The etiology of adult intussusception can be idiopathic, benign, or malignant. Diagnosis is most accurately made with computed tomography, which is sensitive in detecting intussusception as well as potential lead points. Presentation of cases This study presents four adult patients with intussusception. The first three patients are adults with idiopathic intussusception and no evidence of a lead point. The fourth case involves intussusception secondary to a jejunal carcinoid tumor which was treated surgically. Each case has unique features in terms of length and number of intussusceptions, duration of symptoms, and recurrence. Discussion Surgical treatment was once argued to be universally appropriate for adult intussusceptions; however, with increased use of advanced imaging, newer literature is demonstrating that this is not true in all cases. Idiopathic intussusception presents with nonspecific symptoms and can be managed with supportive care when the history and clinical picture indicate low probability of a neoplasm. Conclusion This study aims to raise awareness to the potential diagnosis and management of intussusceptions, particularly the symptomatic idiopathic type in the young adult. PMID:26859872

    The association between intramedullary increased signal intensity (ISI) on T2-weighted magnetic resonance imaging (MRI) and surgical outcome in thoracic ossification of the ligamentum flavum (OLF) remains controversial. We aimed to determine the impact of signal change ratio (SCR) on thoracic OLF surgical outcomes. We retrospectively reviewed 96 cases of thoracic OLF surgery and investigated myelopathy severity, symptom duration, MRI and computed tomographic findings, surgical technique and postoperative recoveries. Surgical outcomes were evaluated according to the modified Japanese Orthopaedic Association (JOA) score and recovery rate. JOA recovery rate <50% was defined as a poor surgical outcome. By multivariate logistic regression analysis, we identified risk factors associated with surgical outcomes. Forty patients (41.7%) had a recovery rate of <50%. In receiver operating characteristic (ROC) curves, the optimal preoperative SCR cutoff value as a predictor of poor surgical outcome was 1.54. Multivariate logistic regression analysis revealed that a preoperative SCR ≥1.54 and symptom duration >12 months were significant risk factors for a poor surgical outcome. These findings suggest that preoperative SCR and duration of symptoms were significant risk factors of surgical outcome for patients with thoracic OLF. Patients with preoperative SCR ≥1.54 can experience poor postoperative recovery. PMID:26960572

    Regenerative mechanisms after surgical injury have been studied in many organs but not in the kidney. Studying surgical injury may provide new insights into mechanisms of kidney regeneration. In rodent models, extrarenal tissues adhere to surgical kidney wound and interfere with healing. We hypothesized that this can be prevented by wrapping injured kidney in a plastic pouch. Adult rats tolerated 5/6 nephrectomy with pouch application well. Histological analysis demonstrates that application of the pouch effectively prevented formation of adhesions and induced characteristic wound healing manifested by formation of granulation tissue. Additionally, selected tubules of the wounded kidney extended into the granulation tissue forming branching tubular epithelial outgrowths (TEOs) without terminal differentiation. Tubular regeneration outside of renal parenchyma was not previously observed, and suggests previously unrecognized capacity for regeneration. Our model provides a novel approach to study kidney wound healing. PMID:24100472

  10. Systematic review of surgical treatment techniques for adult and pediatric patients with pectus excavatum

    PubMed Central

    2014-01-01

    This compares outcome measures of current pectus excavatum (PEx) treatments, namely the Nuss and Ravitch procedures, in pediatric and adult patients. Original investigations that stratified PEx patients based on current treatment and age (pediatric = 0–21; adult 17–99) were considered for inclusion. Outcome measures were: operation duration, analgesia duration, blood loss, length of stay (LOS), outcome ratings, complications, and percentage requiring reoperations. Adult implant patients (18.8%) had higher reoperation rates than adult Nuss or Ravitch patients (5.3% and 3.3% respectively). Adult Nuss patients had longer LOS (7.3 days), more strut/bar displacement (6.1%), and more epidural analgesia (3 days) than adult Ravitch patients (2.9 days, 0%, 0 days). Excluding pectus bar and strut displacements, pediatric and adult Nuss patients tended to have higher complication rates (pediatric - 38%; adult - 21%) compared to pediatric and adult Ravitch patients (12.5%; 8%). Pediatric Ravitch patients clearly had more strut displacements than adult Ravitch patients (0% and 6.4% respectively). These results suggest significantly better results in common PEx surgical repair techniques (i.e. Nuss and Ravitch) than uncommon techniques (i.e. Implants and Robicsek). The results suggest slightly better outcomes in pediatric Nuss procedure patients as compared with all other groups. We recommend that symptomatic pediatric patients with uncomplicated PEx receive the Nuss procedure. We suggest that adult patients receive the Nuss or Ravitch procedure, even though the long-term complication rates of the adult Nuss procedure require more investigation. PMID:24506826

    Objective We compared the skeletal and dental changes that resulted from the use of two methods of intermaxillary fixation (IMF)-miniscrews and surgical archwire-in 74 adult patients who had Class III malocclusion and were treated with the same orthognathic surgical procedure at a hospital in Korea. Methods All the patients underwent Le Fort I osteotomy and bilateral sagittal split ramus osteotomy with rigid fixation. They were divided into two groups according to the type of IMF used-group 1 underwent surgical archwire fixation and group 2 underwent orthodontic miniscrew fixation. In a series of cephalograms for each patient, we compared vertical and horizontal tooth-position measurements: (a) immediately after surgery (T0), (b) 3 months after surgery (T1), and (c) 6 months after surgery (T2). Cephalometric changes within each group were examined using one-way analysis of variance (ANOVA) while the independent samples t-test procedure was used to compare the two groups. Results After surgery, the maxillary incisors tended to be proclined in both groups although there were no significant differences. Incisor overbite increased significantly in both groups from T0 to T1, and the miniscrew group (group 2) showed slightly greater overbite than the archwire group (group 1). Conclusions This study suggest that the use of orthodontic miniscrews and orthodontic surgical archwire for IMF in adult patients results in similar skeletal and dental changes. PMID:25667912

    2010-01-01

    Patients in the cardiothoracic surgical intensive care unit are generally critically ill and undergoing a systemic inflammatory response to cardiopulmonary bypass, ischemia/reperfusion, and hypothermia. This presents several metabolic challenges: hyperglycemia in need of intensive insulin therapy, catabolism, and uncertain gastrointestinal tract function in need of nutritional strategies. Currently, there are controversies surrounding the standard use of intensive insulin therapy and appropriate glycemic targets as well as the use of early enteral nutrition ± parenteral nutrition. In this review, an approach for intensive metabolic support in the cardiothoracic surgical intensive care unit is presented incorporating the most recent clinical evidence. This approach advocates an IIT blood glucose target of 80-110 mg/dL if, it can be implemented safely, with early nutrition support (using parenteral nutrition as needed) to prevent a critical energy debt.

    Night-time rest of the patients hospitalized in Intensive Care is a very important feature within the health/disease process since it has a direct repercussion on their adequate recovery. The objectives of this investigation are: 1) describe how the surgical patients perceive their night-time sleep in the Polyvalent Intensive Care Unit: 2) compare the subjective perception of the patients with the nursing record in the care plan and analyze the degree of agreement between both assessments. Night-time sleep has been studied in 104 patients; surgery patients from emergencies, patients who are intubated, with previous psychiatric treatment, sleep apnea, drinking habit or impossibility of adequate communication were not included. To measure the patient's perception, the five item sleep questionnaire of Richards-Campbell and the assessment of sleep by the nurse, as well as the remaining variables included in a computerized care plan, were used. The total mean score of the sleep on the first post-operative night was 51.42 mm. When the scores obtained in each one of the questionnaire items are analyzed, it is seen that the sleep profile of these patients has been characterized by being light sleep, with frequent wakenings and generally with little difficulty to go back to sleep when woke op or were awakened. The assessment of the night-time sleep performed by the nurse coincides with the perception of the patients on many occasions, and when there is discrepancy, the nurse has overestimated the patient's sleep.

    Approximately 30 minutes of computer access time are required by surgical residents at Stanford University Medical Center (SUMC) to examine the lab values of all patients on a surgical intensive care unit (ICU) service, a task that must be performed several times a day. To reduce the time accessing this information and simultaneously increase the readability and currency of the data, we have created a mobile, pen-based user interface and software system that delivers lab results to surgeons in the ICU. The ScroungeMaster system, loaded on a portable tablet computer, retrieves lab results for a subset of patients from the central laboratory computer and stores them in a local database cache. The cache can be updated on command; this update takes approximately 2.7 minutes for all ICU patients being followed by the surgeon, and can be performed as a background task while the user continues to access selected lab results. The user interface presents lab results according to physiologic system. Which labs are displayed first is governed by a layout selection algorithm based on previous accesses to the patient's lab information, physician preferences, and the nature of the patient's medical condition. Initial evaluation of the system has shown that physicians prefer the ScroungeMaster interface to that of existing systems at SUMC and are satisfied with the system's performance. We discuss the evolution of ScroungeMaster and make observations on changes to physician work flow with the presence of mobile, pen-based computing in the ICU. PMID:8947778

    Purpose To compare demographics, intensive care units (ICU) admission characteristics, and ICU outcomes among adults with childhood-onset chronic conditions (COCC) admitted to U.S. pediatric and adult ICUs. Materials and Methods Retrospective cross-sectional analyses of 6,088 adults aged 19–40 years admitted in 2008 to 70 pediatric ICUs that participated in the Virtual Pediatric Intensive Care Unit Performance Systems and 50 adult ICUs that participated in Project IMPACT. Results COCC were present in 53% of young adults admitted to pediatric units, compared to 9% of those in adult units. The most common COCC in both groups were congenital cardiac abnormalities, cerebral palsy, and chromosomal abnormalities. Adults with COCC admitted to pediatric units were significantly more likely to be younger, have lower functional status, and be non-trauma patients than those in adult units. The median ICU length-of-stay was 2 days and the intensive care unit mortality rate was 5% for all COCC patients with no statistical difference between pediatric or adult units. Conclusions There are marked differences in characteristics between young adults with COCC admitted to PICUs and adult ICUs. Barriers to accommodating these young adults may be reasons why many such adults have not transitioned from pediatric to adult critical care. PMID:25466316

    Evaluation of the performance of the APACHE III (Acute Physiology and Chronic Health Evaluation) ICU (intensive care unit) and hospital mortality models at the Princess Alexandra Hospital, Brisbane is reported. Prospective collection of demographic, diagnostic, physiological, laboratory, admission and discharge data of 5681 consecutive eligible admissions (1 January 1995 to 1 January 2000) was conducted at the Princess Alexandra Hospital, a metropolitan Australian tertiary referral medical/surgical adult ICU ROC (receiver operating characteristic) curve areas for the APACHE III ICU mortality and hospital mortality models demonstrated excellent discrimination. Observed ICU mortality (9.1%) was significantly overestimated by the APACHE III model adjusted for hospital characteristics (10.1%), but did not significantly differ from the prediction of the generic APACHE III model (8.6%). In contrast, observed hospital mortality (14.8%) agreed well with the prediction of the APACHE III model adjusted for hospital characteristics (14.6%), but was significantly underestimated by the unadjusted APACHE III model (13.2%). Calibration curves and goodness-of-fit analysis using Hosmer-Lemeshow statistics, demonstrated that calibration was good with the unadjusted APACHE III ICU mortality model, and the APACHE III hospital mortality model adjusted for hospital characteristics. Post hoc analysis revealed a declining annual SMR (standardized mortality rate) during the study period. This trend was present in each of the non-surgical, emergency and elective surgical diagnostic groups, and the change was temporally related to increased specialist staffing levels. This study demonstrates that the APACHE III model performs well on independent assessment in an Australian hospital. Changes observed in annual SMR using such a validated model support an hypothesis of improved survival outcomes 1995-1999. PMID:12075637

    Outpatient surgical procedures for adult hip and knee reconstruction are gaining interest on a worldwide basis and have been progressively increasing over the last few years. Preoperative screening needs to concentrate on both the patient's comorbidities and home environment to provide a proper alignment of expectations of the surgeon, the patient, and the patient's family. Preoperative multidisciplinary patient information covering all aspects of the upcoming treatment course is a mandatory step, focusing on pain management and early mobilization. Perioperative pain management includes both multimodal and preventive analgesia. Preemptive medications, minimization of narcotics, and combination of general and regional anesthesia are the techniques required in joint arthroplasty performed as an outpatient surgical procedure. A multimodal blood loss management program should be used with preoperative identification of anemia and attention directed toward minimizing blood loss, considering the use of tranexamic acid during the surgical procedure. Postoperative care extends from the initial recovery from anesthesia to the physical therapist's evaluation of the patient's ambulatory status. After the patient has met the criteria for discharge and has been discharged on the same day of the surgical procedure, a nurse should call the patient later at home to check on wound status, pain control, and muscle weakness, which will be further addressed by physiotherapy and education. Implementing outpatient arthroplasty requires monitoring safety, patient satisfaction, and economic impact. PMID:27385689

    Objective To describe rounding practices in Canadian adult Intensive Care Units (ICU) and identify opportunities for improvement. Design Mixed methods design. Cross sectional survey of Canadian Adult ICUs (n = 180) with purposefully sampled follow-up interviews (n = 7). Measurements and Main Results Medical directors representing 111 ICUs (62%) participated in the survey. Rounding practices varied across ICUs with the majority reporting the use of interprofessional rounds (81%) that employed an open (94%) and collaborative (86%) approach, occurred at the patient’s bedside (82%), and started at a standard time (79%) and standard location (56%). Most participants reported that patients (83%) and family members (67%) were welcome to attend rounds. Approximately half of ICUs (48%) used tools to facilitate rounds. Interruptions during rounds were reported to be common (i.e., ≥1 interruption for ≥50% of patients) in 46% of ICUs. Four themes were identified from qualitative analysis of participant responses to open-ended survey questions and interviews: multidisciplinarity, patient and family involvement, factors influencing productivity, and teaching and learning. Conclusions There is considerable variation in current rounding practices in Canadian medical/surgical ICUs. Opportunities exist to improve ICU rounds including ensuring the engagement of essential participants, clearly defining participant roles, establishing a standardized approach to the rounding process, minimizing interruptions, modifying the role of teaching, utilizing a structured rounding tool, and developing a metric for measuring rounding quality.

    We reviewed our 3-year experience in treating interruption of the aorta in adult patients. Clinical profiles, surgical management, and results of early and mid-term follow-up are presented. From August 2001 through June 2003, 7 adult patients underwent an extra-anatomic bypass procedure to repair interruption of the aortic arch. Five patients underwent ventral aortic repair through a mid-sternotomy and an upper midline laparotomy, and 2 patients underwent repair through a left posterolateral thoracotomy. A bovine collagen-impregnated polyester fiber graft was used in 6 patients, and a Gore-Tex graft was interposed in 1 patient. All repairs were performed without cardiopulmonary bypass. Follow-up was complete in all patients. The mean follow-up was 1728 +/- 1 months (range, 9-31 months). No neurologic, renal, or gastrointestinal complications were noted in any patient. There was no in-hospital or late mortality or need for re-intervention. All patients were asymptomatic; however, 5 patients had mild residual hypertension. Graft patency in all the patients was confirmed by computed tomographic angiography. Interruption of the aorta is rare in adults. Ventral aortic repair through a midline approach is our preferred technique for surgical repair of this entity, because it avoids the extensive network of collateral vessels on the chest wall, enables simultaneous treatment of associated lesions, and in all likelihood reduces morbidity and mortality.

    Interhospital transfer (IHT) is associated with mortality in medical and mixed intensive care units (ICUs), but few studies have examined this relationship in a surgical ICU (SICU) setting. We hypothesized that IHT is associated with increased mortality in SICU patients relative to ICU patients admitted within the hospital. We reviewed SICU and transfer center databases from a tertiary academic center over a 2-year period. Inclusion criteria included age 18 years or older and SICU admission 24 hours or greater. Demographic data, admission service, and Acute Physiology and Chronic Health Evaluation (APACHE) II scores were captured. The primary end point was ICU mortality. Univariate logistic regression was used to test the association between variables and mortality. Factors found to be associated with mortality at P < 0.1 were entered into a multivariable model. Of 4542 admissions, 416 arrived by IHT. Compared with the non-IHT group, the IHT group was older (age 58.3 years [interquartile range, 47.8 to 70.6] vs. 57.8 years [interquartile range, 44.1 to 68.8] years, P = 0.036), sicker (APACHE II score 16.5 [interquartile range, 12 to 23] vs. 14 [interquartile range, 10 to 20], P < 0.001), and more likely to be white (82% [n = 341] vs. 69% [n = 2865], P < 0.001). Mortality rates in IHT patients were highest on the emergency surgery (18%), transplant surgery (16%), and gastrointestinal surgery (8%) services. After adjusting for age and APACHE II score, IHT remained a risk factor for ICU mortality (odds ratio, 1.60; 95% confidence interval, 1.04 to 2.45; P = 0.032) in SICU patients. Interhospital transfer is an independent risk factor for mortality in the SICU population; this risk is unevenly distributed through service lines. Further efforts to determine the cause of this association are warranted. PMID:24069990

    Background Hypo-magnesemia is described to occur in as many as 65% of intensive care unit (ICU) patients. Magnesium (Mg) is a cofactor in over 300 enzymatic reactions involving energy metabolism, protein, and nucleic acid synthesis. The membrane pump that creates the electrical gradient across the cell membrane is dependent on Mg, and it is important in the activity of electrically excitable tissues. Since Mg regulates the movement of calcium in smooth muscle cells, it is also important in peripheral vascular tone and blood pressure. Studies have linked hypo-magnesemia to multiple chronic diseases and to a higher mortality rate. Methods To explore trends within our own tertiary care surgical ICU, we sampled our patients’ laboratory records in 2001 and in 2011. Hypo-magnesemia in our ICU is defined as an Mg less than 2.0 mg/dL. Results This retrospective review of all SICU patients from October to December revealed that there was a significant increase (P < 0.01) in the patients with their serum Mg level measured between 2001 (89%) and 2011 (95%). There was a significant decrease (P < 0.001) in patients with hypomagnesemia (< 2 mg/dL) between 2001 (47.5%) and 2011 (33.0%). On the other hand, there was a significant increase (P < 0.001) in patients with normal serum Mg level (> 2 mg/dL) between 2001 (52.5%) and 2011 (67.0%). Conclusions There was not only more monitoring of Mg in 2011, but a lower incidence of hypo-Mg compared to 2001. Possible explanations include changing patterns of antibiotic and diuretic use, less amphotericin use, more frequent laboratory surveillance, and better trained ICU practitioners. PMID:25699122

    The advancement of perioperative medicine is leading to greater diversity in development of pre-surgical interventions, implemented to reduce patient surgical risk and enhance post-surgical recovery. Of these interventions, the prescription of pre-operative exercise training is gathering momentum as a realistic means for enhancing patient surgical outcome. Indeed, the general benefits of exercise training have the potential to pre-operatively optimise several pre-surgical risks factors, including cardiorespiratory function, frailty and cognitive function. Any exercise programme incorporated into the pre-operative pathway of care needs to be effective and time efficient in that any fitness gains are achievable in the limited period between the decision for surgery and operation (e.g. 4 weeks). Fortunately, there is a large volume of research describing effective and time-efficient exercise training programmes within the discipline of sports science. Accordingly, the objective of our commentary is to synthesise contemporary exercise training research, both from non-clinical and clinical populations, with the overarching aim of informing the development of effective and time-efficient pre-surgical exercise training programmes. The development of such exercise training programmes requires the careful consideration of several key principles, namely frequency, intensity, time, type and progression of exercise. Therefore, in light of more recent evidence demonstrating the effectiveness and time efficiency of high-intensity interval training-which involves brief bouts of intense exercise interspersed with longer recovery periods-the principles of exercise training programme design will be discussed mainly in the context of such high-intensity interval training programmes. Other issues pertinent to the development, implementation and evaluation of pre-operative exercise training programmes, such as individual exercise prescription, training session monitoring and potential

    Abstract Adult degenerative scoliosis associated with lumbar stenosis has become a common issue in the elderly population. But its surgical management is on debating. The main issue condenses on the management priority of scoliosis or stenosis. This study is to investigate surgical management strategy and outcome of adult degenerative scoliosis associated with lumbar stenosis. Between January 2003 and December 2010, 108 patients were admitted to the authors’ institution for adult degenerative scoliosis associated with lumbar stenosis. They were divided into 3 groups based on the symptom. Then the surgical management was carried out. The clinical outcome was evaluated according to the Oswestry Disability Index (ODI) and Scoliosis Research Society-22 score (SRS-22 score) at follow up. Group 1 was with primary lumbar stenosis symptom, local decompression and short fusion were performed. Group 2 was with compensated spinal imbalance symptom, local decompression of the symptomatic spinal stenosis and short fusion were performed. Group 3 was with primary spinal imbalance, correction surgery and long fusion were performed. For Group 1, the ODI scores declined from 62.5 ± 4.2 preoperatively to 21.8 ± 2.5 at final follow up, the SRS-22 scores decreased from 44.8 ± 3.2 preoperatively to 70.9 ± 6.0 at final follow up. For Group 2, the ODI and SRS-22 scores were 73.4 ± 8.4 and 40.8 ± 8.5 before the surgery, declined to 22.4 ± 4.2 and 73.2 ± 7.9 at final follow up. For Group 3, the ODI and SRS-22 scores were 73.4 ± 4.9 and 45.3 ± 6.4 before surgery, declined to 30.4 ± 8.9 and 68.8 ± 8.1 at final follow up. It was effective to perform decompression and short fusion for Group 1 and correction surgery and long fusion for Group 3. For Group 2, the compensated imbalance symptom was always provoked by the symptomatic lumbar stenosis. The cases in the Group 2 got well clinical improvements after local surgical intervene on

    Background. Spontaneous onset transethmoidal meningocele is a rare entity among the adult population. Methods. A retrospective chart review was performed and cases of adults diagnosed with spontaneous transethmoidal meningoceles from November 2000 till February 2014 were reported. Data collected included demographics, clinical presentation, diagnostic modalities, and results. Intraoperative findings, the type of surgical reconstruction performed, and the percentage of recurrence, if present, were also reported. Results. Ten cases of spontaneous transethmoidal meningoceles in adults were diagnosed. Eight were females and two males with a mean age of 47.5 years. All patients presented with CSF leakage with or without meningitis. They underwent a reconstruction of the base of skull defect using the temporalis fascia graft in addition to fibrin glue (Tissucol) and Surgicel (Ethicon). In two cases with a larger defect, a piece of septal bone and turbinate mucosa were applied achieving a watertight seal in all cases. Conclusion. Spontaneous transethmoidal meningocele in adults is a rare condition. It usually presents with clear rhinorrhea with or without meningitis and an endoscopic multilayer reconstruction is advocated for treatment of such conditions. PMID:26989762

  9. Frailty and cardiovascular disease: potential role of gait speed in surgical risk stratification in older adults

    PubMed Central

    Chen, Michael A.

    2015-01-01

    Frailty is a state of late life decline and vulnerability, typified by physical weakness and decreased physiologic reserve. The epidemiology and pathophysiology of frailty share features with those of cardiovascular disease. Gait speed can be used as a measure of frailty and is a powerful predictor of mortality. Advancing age is a potent risk factor for cardiovascular disease and has been associated with an increased risk of adverse outcomes. Older adults comprise approximately half of cardiac surgery patients, and account for nearly 80% of the major complications and deaths following surgery. The ability of traditional risk models to predict mortality and major morbidity in older patients being considered for cardiac surgery may improve if frailty, as measured by gait speed, is included in their assessment. It is possible that in the future frailty assessment may assist in choosing among therapies (e.g., surgical vs. percutaneous aortic valve replacement for patients with aortic stenosis).

    Percutaneous pulmonary balloon valvuloplasty as a procedure of choice in adults has been established since the last three decades. Even though the complications are rare, they are scarcely reported in the literature. We report such a case in an adult female patient of severe pulmonary valular stenosis in whom, entrapped catheter across the fossa ovalis was noted in chest x-ray and echocardiogram following unsuccessful percutaneous pulmonary balloon valvuloplasty. Our case emphasizes this rare complication and its successful surgical outcome. PMID:24757650

    Although outcomes of intensive care for patients undergoing hematopoietic stem cell transplantation (HSCT) have improved in the last two decades, the short-term mortality still remains above 50% among allogeneic HSCT patients. Better selection of HSCT patients for intensive care, and consequently reduction of non-beneficial care, may reduce financial costs and alleviate patient suffering. We reviewed the studies on intensive care outcomes of patients undergoing HSCT published since 2000. The risk factors for intensive care unit (ICU) admission identified in this report were primarily patient and transplant related: HSCT type (autologous vs allogeneic), conditioning intensity, HLA mismatch, and graft-versus-host disease (GVHD). At the same time, most of the factors associated with ICU outcomes reported were related to the patients’ functional status upon development of critical illness and interventions in ICU. Among the many possible interventions, the initiation of mechanical ventilation was the most consistently reported factor affecting ICU survival. As a consequence, our current ability to assess the benefit or futility of intensive care is limited. Until better ICU or hospital mortality prediction models are available, based on the available evidence, we recommend practitioners to base their ICU admission decisions on: Patient pre-transplant comorbidities, underlying disease status, GVHD diagnosis/grade, and patients’ functional status at the time of critical illness.

    This ethnography explores communication around critically ill surgical patients in three surgical intensive care units (ICUs) in Canada. A boundary framework is used to articulate how surgeons', intensivists', and nurses' communication practices shape and are shaped by their respective disciplinary perspectives and experiences. Through 50 hours of observations and 43 interviews, these health care providers are found to engage in seven communication behaviors that either mitigate or magnify three contested symbolic boundaries: expertise, patient ownership, and decisional authority. Where these boundaries are successfully mitigated, experiences of collaborative, high-quality patient care are produced; by contrast, boundary magnification produces conflict and perceptions of unsafe patient care. Findings reveal that high quality and safe patient care are produced through complex social and cultural interactions among surgeons, intensivists, and nurses that are also expressions of knowledge and power. This enhances our understanding of why current quality improvement efforts targeting communication may be ineffective. PMID:26481945

    The need exists for a simplified and ecomonical computer based monitoring system for critically ill surgical patients. Such a system would enjoy widespread use in surgical intensive care units in regional, as well as larger community hospitals. We have assembled such a system which provides digital readout of the usual physiologic parameters, and also provide computer storage of accumulated data for review and evaluation of patient care. The computer provides graphic and digital display and digital printout for subsequent inclusion in the patient records. Most frequent indications for this system include the development of acute respiratory insufficiency or acute circulatory failure due to invasive sepsis and/or severe arteriosclerotic cardiovascular disease. Information most beneficial in patient care included measurement of cardiac output;alveolar arterial oxygen gradient. ImagesFigure 1Figure 5Figure 9Figure 11

    2015-01-01

    Although acute myeloid leukemia (AML) is primarily a disease of older adults (age ≥60 years), the optimal treatment for older adults remains largely undefined. Intensive chemotherapy is rarely beneficial for frail older adults or those with poor-risk disease, but criteria that define fitness and/or appropriateness for intensive chemotherapy remain to be standardized. Evaluation of disease-related and patient-specific factors in the context of clinical decision making has therefore been largely subjective. A uniform approach to identify those patients most likely to benefit from intensive therapies is needed. Here, we review currently available objective measures to define older adults with AML who are ineligible for intensive chemotherapy, and discuss promising investigational approaches. PMID:26697412

    OBJECTIVES: (a) To assess the impact of HIV status (HIV negative, HIV positive, AIDS) on the outcome of patients admitted to intensive care units for diseases unrelated to HIV; (b) to decide whether a positive test result for HIV should be a criterion for excluding patients from intensive care for diseases unrelated to HIV. DESIGN: A prospective double blind study of all admissions over six months. HIV status was determined in all patients by enzyme linked immunosorbent assay (ELISA), immunofluorescence assay, western blotting, and flow cytometry. The ethics committee considered the clinical implications of the study important enough to waive patients' right to informed consent. Staff and patients were blinded to HIV results. On discharge patients could be advised of their HIV status if they wished. SETTING: A 16 bed surgical intensive care unit. SUBJECTS: All 267 men and 135 women admitted to the unit during the study period. INTERVENTIONS: None. MAIN OUTCOME MEASURES: APACHE II score (acute physiological, age, and chronic health evaluation), organ failure, septic shock, durations of intensive care unit and hospital stay, and intensive care unit and hospital mortality. RESULTS: No patient had AIDS. 52 patients were tested positive for HIV and 350 patients were tested negative. The two groups were similar in sex distribution but differed significantly in age, incidence of organ failure (37 (71%) v 171 (49%) patients), and incidence of septic shock (20 (38%) v 54 (15%)). After adjustment for age there were no differences in intensive care unit or hospital mortality or in the durations of stay in the intensive care unit or hospital. CONCLUSIONS: Morbidity was higher in HIV positive patients but there was no difference in mortality. In this patient population a positive HIV test result should not be a criterion for excluding a patient from intensive care. PMID:9133887

    Background: Practice parameters for the treatment of obstructive sleep apnea syndrome (OSAS) in adults by surgical modification of the upper airway were first published in 1996 by the American Academy of Sleep Medicine (formerly ASDA). The following practice parameters update the previous practice parameters. These recommendations were reviewed and approved by the Board of Directors of the American Academy of Sleep Medicine. Methods: A systematic review of the literature was performed, and the GRADE system was used to assess the quality of evidence. The findings from this evaluation are provided in the accompanying review paper, and the subsequent recommendations have been developed from this review. The following procedures have been included: tracheostomy, maxillo-mandibular advancement (MMA), laser assisted uvulopalatoplasty (LAUP), uvulopalatopharyngoplasty (UPPP),radiofrequency ablation (RFA), and palatal implants. Recommendations: The presence and severity of obstructive sleep apnea must be determined before initiating surgical therapy (Standard). The patient should be advised about potential surgical success rates and complications, the availability of alternative treatment options such as nasal positive airway pressure and oral appliances, and the levels of effectiveness and success rates of these alternative treatments (Standard). The desired outcomes of treatment include resolution of the clinical signs and symptoms of obstructive sleep apnea and the normalization of sleep quality, the apnea-hypopnea index, and oxyhemoglobin saturation levels (Standard). Tracheostomy has been shown to be an effective single intervention to treat obstructive sleep apnea. This operation should be considered only when other options do not exist, have failed, are refused, or when this operation is deemed necessary by clinical urgency (Option). MMA is indicated for surgical treatment of severe OSA in patients who cannot tolerate or who are unwilling to adhere to positive

    Viral lower respiratory tract infections (LRTIs) are an underappreciated cause of critical illness in adults. Recent advances in viral detection techniques over the past decade have demonstrated viral LRTIs are associated with rates of morbidity, mortality, and health care utilization comparable to those of seen with bacterial community acquired and nosocomial pneumonias. In this review, we describe the relationship between viral LRTIs and critical illness, as well as discuss relevant clinical features and management strategies for the more prevalent respiratory viral pathogens.

    AML is currently the most common indication for reduced-intensity conditioned (RIC) allo-SCT. Reduced-intensity regimens allow a potent GVL response to occur with minimized treatment-related toxicity in patients of older age or with comorbidities that preclude the use of myeloablative conditioning. Whether RIC SCT is appropriate for younger and more standard risk patients is not well defined and the field is changing rapidly; a prospective randomized trial of myeloablative vs RIC (BMT-CTN 0901) was recently closed when early results indicated better outcomes for myeloablative regimens. However, detailed results are not available, and all patients in that study were eligible for myeloablative conditioning. RIC transplants will likely remain the standard of care as many patients with AML are not eligible for myeloablative conditioning. Recent publication of mature results from retrospective and prospective cohorts provide contemporary efficacy and toxicity data for these attenuated regimens. In addition, recent studies explore the use of alternative donors, introduce regimens that attempt to reduce toxicity without reducing intensity, and identify predictive factors that pave the way to personalized approaches. These studies paint a picture of the future of RIC transplants. Here we review the current status of RIC allogeneic SCT in AML. PMID:25730186

    We began our program in September 1992, using the Nucleus 22 Channel Cochlear Implant. To date, we have operated on four patients, one child with congenital hearing loss, two prelinguistically deaf adults and one perilingually deaf adult. Our results have shown a significant increase in auditory and speech reception and perception skills in the child. The perilingually deaf adult is able to understand speech in open set speech discrimination testing and, although we do not expect open set speech discrimination in the prelinguistically deaf adults, to date their results have been satisfactory. The two prelingually deaf adults are in an audiological rehabilitation program. Their response in prosodic aspects of speech and lipreading ability with sound have improved significantly. The only surgical complication was an infection of the flap in the child, but it was treated satisfactorily with i.v. penicillin. PMID:8205978

    OBJECTIVE Debate exists regarding the merits and shortcomings of an indirect bypass procedure for treating adult patients with moyamoya disease (MMD). Considerable variation in neovascularization occurs among different organs in patients with diabetes mellitus. Here, the effect of encephaloduroarteriosynangiosis on MMD associated with Type 2 diabetes mellitus (T2DM) is evaluated. METHODS A retrospective and 1:2 matched case-control study was conducted in moyamoya patients with or without T2DM (n = 180). Postoperative collateral formations were graded according to the Modified Collateral Grading System that originated from the Matsushima Angiographic Stage Classification. Neurological function outcomes before and after the operation were evaluated according to the modified Rankin Scale. Univariate and multivariate logistic regression analyses were performed to determine the risk factors for clinical outcome. RESULTS There was no statistically significant difference in the constituent ratios of initial symptom and preoperative Suzuki stage between patients with and without T2DM. Progression of angiopathy around the circle of Willis was postoperatively observed in bilateral internal carotid arteries in both groups. Patients with T2DM had a higher postoperative Suzuki stage (p < 0.01) and more frequent development of collateral angiogenesis germinating from the external carotid after indirect revascularization procedures in the surgical cerebral hemisphere (82.7% vs 72.2%; p < 0.05). The extent of postoperative collateral formation in patients with diabetes mellitus was significantly higher (p < 0.01). Postoperative clinical improvement in the diabetes group was more common after revascularization procedures (p < 0.05), and the diabetes group had lower modified Rankin Scale scores (p < 0.05) in comparison with the nondiabetes group. Late postoperative stroke and posterior cerebral artery involvement were identified as predictors of unfavorable clinical outcome in both

    Our goal was to determine if a computerized teaching tool is an effective teaching method for nurses in a high-stress fast-paced intensive care unit. We also measured the level of satisfaction with this method of instruction. Thirty-six surgical intensive care nurses used a Web-based Microsoft PowerPoint presentation located on the intranet at nursing stations located on the surgical intensive care unit (SICU). The presentation was designed to provide instruction regarding the methodology and use of APACHE III prior to its implementation. Paired t-tests were performed to compare the results of a pretest and posttest. The questions were divided into two types: methodology and use. After the nurses completed their training sessions, they were asked to complete a questionnaire. The questionnaire questions were rated one a 1 to 5 scale. The average scores were higher on the posttest compared to the pretest (63.2% vs. 69.1%, p = 0.03). The methodology scores were higher on the posttest (74.3% vs. 88.2%, p = 0.001), while the use scores remained the same at 78.1% vs. 75.0%. Our Web-based teaching tool is an effective way to train nurses to understand the APACHE III medical system. The tool was effective at conveying the APACHE III medical systems methodology but was not effective in explaining the usefulness of the system. Most important, the nurses thought the browser-based teaching tool was easily accessible and an effective way to communicate new material to the medical staff. PMID:11280152

    2010-01-01

    Background Surgical site infections (SSIs) are associated with significant morbidity, mortality, and resource utilization and are potentially preventable. Peri-operative hyperglycaemia has been associated with increased SSIs and previous recommendations have been to treat glucose levels above 200 mg/dL. However, recent studies have questioned the optimal glycaemic control regimen to prevent SSIs. Whether the benefits of strict or intensive glycaemic control with insulin infusion as compared to conventional management outweigh the risks remains controversial. Objectives To summarise the evidence for the impact of glycaemic control in the peri-operative period on the incidence of surgical site infections, hypoglycaemia, level of glycaemic control, all-cause and infection-related mortality, and hospital length of stay and to investigate for differences of effect between different levels of glycaemic control. Search strategy A search strategy was developed to search the following databases: Cochrane Wounds Group Specialised Register (searched 25 March 2009), The Cochrane Central Register of Controlled Trials, The Cochrane Library 2009, Issue 1; Ovid MEDLINE (1950 to March Week 2 2009); Ovid EMBASE (1980 to 2009 Week 12) and EBSCO CINAHL (1982 to March Week 3 2009). The search was not limited by language or publication status. Selection criteria Randomised controlled trials (RCTs) were eligible for inclusion if they evaluated two (or more) glycaemic control regimens in the peri-operative period (within one week pre-, intra-, and/or post-operative) and reported surgical site infections as an outcome. Data collection and analysis The standard method for conducting a systematic review in accordance with the Cochrane Wounds Group was used. Two review authors independently reviewed the results from the database searches and identified relevant studies. Two review authors extracted study data and outcomes from each study and reviewed each study for methodological quality. Any

    Context Family caregivers are a vital resource in the recovery of intensive care unit (ICU) survivors. Of concern, the stress associated with this role can negatively affect caregiver health. Fatigue, an important health indicator, has been identified as a predictor of various illnesses, greater use of health services, and early mortality. Examining the impact of fatigue on caregivers’ physical health can assist in identifying critical time points and potential targets for intervention. Objectives To describe self-reported fatigue in caregivers of ICU survivors from patients’ ICU admission to ≤ two weeks, two- and four-months post-ICU discharge. Methods Patient-caregiver pairs were enrolled from a medical ICU. Caregiver fatigue was measured using the Short-Form-36 Health Survey Vitality subscale (SF-36 Vitality). Caregiver psychobehavioral stress responses included depressive symptoms, burden, health risk behaviors, and sleep quality. Patient data included self-reported physical symptoms and disposition (home vs. institution). Results Forty seven patient-caregiver pairs were initially enrolled. Clinically significant fatigue (SF-36 Vitality ≤ 45) was reported by 43% to 53% of caregivers across the time points and these caregivers reported worse scores in measures of depressive symptoms, burden, health risk behaviors and sleep quality, and patients’ symptom burden. In 26 caregivers with data for all time points (55% of the total sample), SF-36 Vitality scores showed trends of improvement when the patient returned home and greater impairment when institutionalization continued. Conclusion In caregivers of ICU survivors, fatigue is common and potentially linked with poor psychobehavioral responses. Worsening fatigue was associated with greater symptom distress and long-term patient institutionalization. PMID:24439845

    Objective Although successful models for palliative care delivery and quality improvement in the intensive care unit have been described, their applicability in surgical intensive care unit settings has not been fully addressed. We undertook to define specific challenges, strategies, and solutions for integration of palliative care in the surgical intensive care unit. Data Sources We searched the MEDLINE database from inception to May 2011 for all English language articles using the term “surgical palliative care” or the terms “surgical critical care,” “surgical ICU,” “surgeon,” “trauma” or “transplant,” and “palliative care” or “end-of- life care” and hand-searched our personal files for additional articles. Based on review of these articles and the experiences of our interdisciplinary expert Advisory Board, we prepared this report. Data Extraction and Synthesis We critically reviewed the existing literature on delivery of palliative care in the surgical intensive care unit setting focusing on challenges, strategies, models, and interventions to promote effective integration of palliative care for patients receiving surgical critical care and their families. Conclusions Characteristics of patients with surgical disease and practices, attitudes, and interactions of different disciplines on the surgical critical care team present distinctive issues for intensive care unit palliative care integration and improvement. Physicians, nurses, and other team members in surgery, critical care and palliative care (if available) should be engaged collaboratively to identify challenges and develop strategies. “Consultative,” “integrative,” and combined models can be used to improve intensive care unit palliative care, although optimal use of trigger criteria for palliative care consultation has not yet been demonstrated. Important components of an improvement effort include attention to efficient work systems and practical tools and to

    High-intensity, focused ultrasound (HIFU) applicators have been developed for arresting bleeding with the ultimate intent of use in surgery. The design uses a tapered titanium component for transmission coupling of the ultrasound energy from a spherically curved transducer to biological tissues. The nominal operating frequency is 5.5 MHz, in a highly resonant mode (quality factor of 327 with water load). Liquid cooling is used to remove energy loss important at net applied power greater than 18 W/cm2 at the surface of the piezoelectric element. A downward resonance frequency shift (>20 kHz) occurs, even with cooling, as the applicator warms with normal operation. A feedback technique is used for maintaining the excitation near optimum resonance. Standing wave ratios of the applied power of 1.6 or less are thus sustained. The system and applicators have been found to be highly robust, effective in achieving hemostasis in the hemorrhaging liver, spleen, lung, or blood vessels in rabbit and pig experiments. One unit has been operated for over 1.7 hours in treating organ hemorrhage in blunt trauma experiments with nine swine with electrical net power of up to 158 W (31 W/cm2 across the transducer) and intensity of 2560 W/cm2 at focus.

The small number of studies reporting the outcome beyond a 5-year follow-up is in contrast to the wide application of the periacetabular osteotomy. The performed analysis of predictors of conversion to total hip replacement following periacetabular osteotomy documented the importance of different biomechanical and degenerative factors. Knowledge about factors predicting early conversion to total hip replacement has the potential to refine patient selection and to improve treatment by periacetabular osteotomy. Cartilage thickness was documented to be preserved up to 2,5 years after periacetabular osteotomy. All but 1 hip joint had acetabular labral tears, thus indicating that the presence of labral tears does not accelerate cartilage degeneration after periacetabular osteotomy. PMID:22677250

    OBJECTIVE To analyze the incremental cost-utility ratio for the surgical treatment of hip fracture in older patients. METHODS This was a retrospective cohort study of a systematic sample of patients who underwent surgery for hip fracture at a central hospital of a macro-region in the state of Minas Gerais, Southeastern Brazil between January 1, 2009 and December 31, 2011. A decision tree creation was analyzed considering the direct medical costs. The study followed the healthcare provider's perspective and had a one-year time horizon. Effectiveness was measured by the time elapsed between trauma and surgery after dividing the patients into early and late surgery groups. The utility was obtained in a cross-sectional and indirect manner using the EuroQOL 5 Dimensions generic questionnaire transformed into cardinal numbers using the national regulations established by the Center for the Development and Regional Planning of the State of Minas Gerais. The sample included 110 patients, 27 of whom were allocated in the early surgery group and 83 in the late surgery group. The groups were stratified by age, gender, type of fracture, type of surgery, and anesthetic risk. RESULTS The direct medical cost presented a statistically significant increase among patients in the late surgery group (p < 0.005), mainly because of ward costs (p < 0.001). In-hospital mortality was higher in the late surgery group (7.4% versus 16.9%). The decision tree demonstrated the dominance of the early surgery strategy over the late surgery strategy: R$9,854.34 (USD4,387.17) versus R$26,754.56 (USD11,911.03) per quality-adjusted life year. The sensitivity test with extreme values proved the robustness of the results. CONCLUSIONS After controlling for confounding variables, the strategy of early surgery for hip fracture in the older adults was proven to be dominant, because it presented a lower cost and better results than late surgery.

    Preparation for replacing the large proportion of staff nurses reaching retirement age in the next few decades in the United States is essential to continue delivering high-quality nursing care and improving patient outcomes. Retaining experienced critical care nurses is imperative to successfully implementing the orientation of new inexperienced critical care nurses. It is important to understand factors that affect work engagement to develop strategies that enhance nurse retention and improve the quality of patient care. Nurses' experience of moral distress has been measured in medical intensive care units but not in surgical trauma care units, where nurses are exposed to patients and families faced with sudden life-threatening, life-changing patient consequences.This pilot study is a nonexperimental, descriptive, correlational design to examine the effect of compassion satisfaction, compassion fatigue, moral distress, and level of nursing education on critical care nurses' work engagement. This is a partial replication of Lawrence's dissertation. The study also asked nurses to describe sources of moral distress and self-care strategies for coping with stress. This was used to identify qualitative themes about the nurse experiences. Jean Watson's theory of human caring serves as a framework to bring meaning and focus to the nursing-patient caring relationship.A convenience sample of 26 of 34 eligible experienced surgical intensive care unit trauma nurses responded to this survey, indicating a 77% response rate. Twenty-seven percent of the nurses scored high, and 73% scored average on compassion satisfaction. On compassion fatigue, 58% scored average on burnout and 42% scored low. On the secondary traumatic stress subscale, 38% scored average, and 62% scored low. The mean moral distress situations subscale score was 3.4, which is elevated. The mean 9-item Utrecht Work Engagement Scale total score, measuring work engagement, was 3.8, which is considered low

    The goal of this study was to examine the adult surgical emergencies seen at the Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, with a view to proffering preventive solutions where appropriate and improving outcome. From the register of patients seen at the Casualty department and from the operations register in the main operation room of NAUTH, names and hospital numbers of adult patients treated as emergencies over a 5-year period, from 7 September 1998 to 6 September 2003, were obtained. The hospital folders were then retrieved from the Records Department. From each folder, the following details about each patient were extracted: age, sex, diagnosis at presentation, causative factors, treatment given, and outcome. A total of 902 adult patients were treated during the period. The commonest emergency operation was appendectomy for acute appendicitis in 139 patients (97 women and 42 men), followed closely by road traffic accidents (RTAs) involving 137 patients (103 men and 34 women). Gunshot injuries, which resulted mainly from armed robbery attacks, accounted for 127 cases. More men (113) sustained gunshot injuries than women (14). Of the 92 cases of acute intestinal obstruction seen, 62 occurred in women and 30 in men. Some 126 men presented with acute urinary retention, and two others presented with priapism. Governments at various levels should provide modern diagnostic tools for the accurate preoperative diagnosis of surgical emergencies in hospitals. Governments should also inculcate strict discipline into drivers using the highways, particularly in relation to abuse of alcohol and drugs. Good roads and adequate security should be provided for the people. The need for Pre-Hospital Care for the efficient evacuation of accident victims is emphasized. These measures will help to improve the management and outcome of surgical emergencies, and decrease the number of surgical emergencies resulting from RTAs and gunshot wounds. PMID:15880283

    Objective: To assess whether non-surgical periodontal treatment is associated with changes in serological markers of systemic inflammation. Materials and Methods: Thirty-five systemically healthy subjects with severe generalized periodontitis meeting the inclusion criteria participated in a four-month single blind interventional trial of which thirty-two completed the study. Periodontal parameters and inflammatory markers [C-reactive protein (CRP) and plasma fibrinogen] and also the white blood cell count (WBC) were evaluated prior to and four months after delivery of intensive non-surgical periodontal therapy with simultaneous lavage of chlorhexidine 0.1% from the tip of the ultrasonic instrument into the pockets. Results: Significant differences in serum CRP levels were observed four months after treatment compared to the baseline (1.85, SD=1.93 vs 2.46, SD=2.32, respectively, P<0.0001). Periodontal treatment also resulted in a significant difference in WBC and neutrophil counts compared to the baseline (P<0.0001). The reduction in fibrinogen levels was not significant at the end of the research period. Significant improvement in the pocket probing depth and clinical attachment level for pockets with initially 4–6 mm and then more than 7 mm depth was observed. Changes in plaque and bleeding scores were also statistically significant (82.75 vs. 35.84 and 19.03 vs. 1.81, respectively). Conclusion: Periodontal treatment is effective in reducing CRP levels and white blood cell count, while fibrinogen levels are not influenced by periodontal therapy. Periodontal treatment may therefore decrease the systemic inflammatory burden in patients with advanced periodontitis. PMID:21998772

    Introduction The clinical value of daily routine chest radiographs (CXRs) in critically ill patients is unknown. We conducted this study to evaluate how frequently unexpected predefined major abnormalities are identified with daily routine CXRs, and how often these findings lead to a change in care for intensive care unit (ICU) patients. Method This was a prospective observational study conducted in a 28-bed, mixed medical–surgical ICU of a university hospital. Results Over a 5-month period, 2,457 daily routine CXRs were done in 754 consecutive ICU patients. The majority of these CXRs did not reveal any new predefined major finding. In only 5.8% of daily routine CXRs (14.3% of patients) was one or more new and unexpected abnormality encountered, including large atelectases (24 times in 20 patients), large infiltrates (23 in 22), severe pulmonary congestion (29 in 25), severe pleural effusion (13 in 13), pneumothorax/pneumomediastinum (14 in 13), and malposition of the orotracheal tube (32 in 26). Fewer than half of the CXRs with a new and unexpected finding were ultimately clinically relevant; in only 2.2% of all daily routine CXRs (6.4% of patients) did these radiologic abnormalities result in a change to therapy. Subgroup analysis revealed no differences between medical and surgical patients with regard to the incidence of new and unexpected findings on daily routine CXRs and the effect of new and unexpected CXR findings on daily care. Conclusion In the ICU, daily routine CXRs seldom reveal unexpected, clinically relevant abnormalities, and they rarely prompt action. We propose that this diagnostic examination be abandoned in ICU patients. PMID:16420655

    Background: Nosocomial infections (NIs) in the postoperative period not only increase morbidity and mortality, but also impose a significant economic burden on the health care infrastructure. This retrospective study was undertaken to (a) evaluate the incidence, characteristics, risk factors and outcomes of NIs and (b) identify common microorganisms responsible for infection and their antibiotic resistance profile in our Cardiac Surgical Intensive Care Unit (CSICU). Patients and Methods: After ethics committee approval, the CSICU records of all patients who underwent cardiovascular surgery between January 2013 and December 2014 were reviewed retrospectively. The incidence of NI, distribution of NI sites, types of microorganisms and their antibiotic resistance, length of CSICU stay, and patient-outcome were determined. Results: Three hundred and nineteen of 6864 patients (4.6%) developed NI after cardiac surgery. Lower respiratory tract infections (LRTIs) accounted for most of the infections (44.2%) followed by surgical-site infection (SSI, 11.6%), bloodstream infection (BSI, 7.5%), urinary tract infection (UTI, 6.9%) and infections from combined sources (29.8%). Acinetobacter, Klebsiella, Escherichia coli, and Staphylococcus were the most frequent pathogens isolated in patients with LRTI, BSI, UTI, and SSI, respectively. The Gram-negative bacteria isolated from different sources were found to be highly resistant to commonly used antibiotics. Conclusion: The incidence of NI and sepsis-related mortality, in our CSICU, was 4.6% and 1.9%, respectively. Lower respiratory tract was the most common site of infection and Gram-negative bacilli, the most common pathogens after cardiac surgery. Antibiotic resistance was maximum with Acinetobacter spp. PMID:27052070

    This manuscript discusses the current surgical management of glioblastoma. This paper highlights the common pathophysiology attributes of glioblastoma, surgical options for diagnosis/treatment, current thoughts of extent of resection (EOR) of tumor, and post-operative (neo)adjuvant treatment. Glioblastoma is not a disease that can be cured with surgery alone, however safely performed maximal surgical resection is shown to significantly increase progression free and overall survival while maximizing quality of life. Upon invariable tumor recurrence, re-resection also is shown to impact survival in a select group of patients. As adjuvant therapy continues to improve survival, the role of surgical resection in the treatment of glioblastoma looks to be further defined. PMID:26207249

    Background The management of brachial plexus injuries due to gunshot wounds is a surgical challenge. Better surgical strategies based on clinical and electrophysiological patterns are needed. The aim of this study is to clarify the factors which may influence the surgical technique and outcome of the brachial plexus lesions caused by gunshot injuries. Methods Two hundred and sixty five patients who had brachial plexus lesions caused by gunshot injuries were included in this study. All of them were male with a mean age of 22 years. Twenty-three patients were improved with conservative treatment while the others underwent surgical treatment. The patients were classified and managed according to the locations, clinical and electrophysiological findings, and coexisting lesions. Results The wounding agent was shrapnel in 106 patients and bullet in 159 patients. Surgical procedures were performed from 6 weeks to 10 months after the injury. The majority of the lesions were repaired within 4 months were improved successfully. Good results were obtained in upper trunk and lateral cord lesions. The outcome was satisfactory if the nerve was intact and only compressed by fibrosis or the nerve was in-contunuity with neuroma or fibrosis. Conclusion Appropriate surgical techniques help the recovery from the lesions, especially in patients with complete functional loss. Intraoperative nerve status and the type of surgery significantly affect the final clinical outcome of the patients. PMID:19627573

    A total of 473 strains of Enterobacteriaceae, including Escherichia coli, Klebsiella spp., Proteus spp., Citrobacter spp., Enterobacter spp., Serratia spp. and Providencia spp., were isolated from patients admitted to intensive care units and surgical units in Russia. About 90% of the isolates carried factors resistant to beta-lactams. The isolation rates of the extended-spectrum beta-lactamase (ESBL) producer defined in this study among E. coli, Klebsiella spp. and Proteus spp. were 45%, 48% and 17%, respectively. In the settings with high prevalence of the ESBL producer, flomoxef, which belongs to the oxacephem subgroup, and carbapenems retain their activity. The MIC₅₀ of flomoxef, meropenem and imipenem against total isolates were 1 µg/mL, ≤ 0.063 µg/mL and 0.25 µg/mL, respectively. Fifty-five carbapenem-resistant strains were isolated in this study. The carbapenem resistant rates of E. coli, Klebsiella spp. and Proteus spp. were 3%, 16% and 29%, respectively PMID:27290829

    This study investigated the associations between types and intensity of life events and symptoms of depression among adults with intellectual disabilities. A community sample (N = 593) was screened for current depression and exposure to life events (i.e., loss, illness, change, and bullying) during the previous 12 months. Symptoms of depression were measured using the Psychopathology Checklists for Adults With Intellectual Disabilities. Exposure to three of the four types of life events studied (loss, illness, and bullying) and the intensity of the events were associated with depression, particularly in the cases of loss of relatives and bullying. Quality of care moderated the association between bullying and depression and may buffer the adverse consequences of bullying. PMID:27611352

    There has been a steady rise in the prevalence of severe congenital heart disease (CHD) in adults because of improved treatment and survival during childhood. This has resulted in a shift in CHD morbidity and mortality beyond 18 years of age. The healthcare community must be prepared to meet this new challenge. Adult cardiologists need to be aware of common CHD, such as tetralogy of Fallot (TOF), as they will encounter adults with this CHD in their practice. With routine monitoring, cardiac imaging, early intervention, and treatment as highlighted in this report, continued improvement in the long-term fitness and avoidance of late complications for adult TOF patient is anticipated.

    Objective To determine the impact of elimination of daily routine chest radiographs (CXRs) in a mixed medical–surgical intensive care unit (ICU) on utility of on demand CXRs, length of stay (LOS) in ICU, readmission rate, and mortality rate. Design and setting Prospective, nonrandomized, controlled study in a 28-bed ICU. Analysis included data of all admitted ICU patients during 5 months before and after elimination of daily routine CXRs. Results Before elimination, 2457 daily routine CXRs and 1437 on demand CXRs were obtained from 754 patients. After elimination, 1267 CXRs were obtained from 622 patients. The ratio of CXRs/patient day decreased from 1.1 ± 0.3 to 0.6 ± 0.4 (p < 0.05). Elimination did not result in a change in utility and timing of on demand CXRs. The absolute diagnostic and therapeutic value of on demand CXRs increased with elimination of daily routine CXRs: before intervention, 147 unexpected predefined abnormalities were found (10.2% of all on demand CXRs in 15.9% of all patients), of which 57 (3.9%) in 6.4% of all patients led to a change in therapy. After intervention, 156 unexpected predefined abnormalities were found (11.6%; p < 0.05), of which 61 (4.8%) in 9.5% of all patients (p < 0.05) led to a change in therapy. The LOS in ICU, readmission rate and ICU, and hospital mortality rate were not influenced by the change in strategy. Conclusions Elimination of daily routine CXRs reduced the number of CXRs in a mixed medical–surgical ICU, while not affecting readmission rate and ICU and hospital mortality rates.

    Hippocampal atrophy is associated with memory impairment and dementia and serves as a key biomarker in the preclinical stages of Alzheimer's disease. Physical activity, one of the most promising behavioral interventions to prevent or delay cognitive decline, has been shown to be associated with hippocampal volume; specifically increased aerobic activity and fitness may have a positive effect on the size of the hippocampus. The majority of older adults, however, are sedentary and have difficulty initiating and maintaining exercise programs. A modestly more active lifestyle may nonetheless be beneficial. This study explored whether greater objectively measured daily walking activity was associated with larger hippocampal volume. We additionally explored whether greater low-intensity walking activity, which may be related to leisure-time physical, functional, and social activities, was associated with larger hippocampal volume independent of exercise and higher-intensity walking activity. Segmentation of hippocampal volumes was performed using Functional Magnetic Resonance Imaging of the Brain's Software Library (FSL), and daily walking activity was assessed using a step activity monitor on 92, nondemented, older adult participants. After controlling for age, education, body mass index, cardiovascular disease risk factors, and the Mini Mental State Exam, we found that a greater amount, duration, and frequency of total daily walking activity were each associated with larger hippocampal volume among older women, but not among men. These relationships were specific to hippocampal volume, compared with the thalamus, used as a control brain region, and remained significant for low-intensity walking activity, independent of moderate- to vigorous-intensity activity and self-reported exercise. This is the first study, to our knowledge, to explore the relationship between objectively measured daily walking activity and hippocampal volume in an older adult population. Findings

    Introduction Delayed union and non-union of displaced femoral neck fractures remains a difficult clinical problem for orthopaedic surgeons. In the physiologically young patient, every effort should be made to preserve the native hip joint. We present two cases of ununited femoral neck fractures in young adults who were successfully treated with low-intensity pulsed ultrasound (LIPUS) and showed satisfactory results. Presentation of case 1 A 41-year-old woman was involved in a motor vehicle crash and was diagnosed with displaced femoral neck fracture. Eleven months after internal fixation, a computed tomography (CT) scan revealed the presence of non-union of the femoral neck. LIPUS treatment was therefore initiated. After eight months, the fracture was completely consolidated. Presentation of case 2 A 39-year-old man was involved in a cycling accident and was diagnosed with displaced femoral neck fracture. Thirteen weeks after internal fixation, a CT scan revealed delayed union of the femoral neck. LIPUS treatment was therefore initiated. After six months, the fracture was completely consolidated. Conclusion We suggest use of LIPUS as a possible treatment approach for delayed union and non-union of displaced femoral neck fractures in young patients before considering further surgical intervention.

    Background: Prevention of ventilator-associated pneumonia is a healthcare goal. Although data is inconsistent, some studies suggest that oral chlorhexidine may decrease rates of pneumonia in mechanically-ventilated patients. We sought to assess the rate of pneumonia in the Surgical Intensive Care Unit (SICU) pre and post implementation of routine chlorhexidine mouthwash prophylaxis. Materials and Methods: A retrospective cohort study was conducted, including patients between 1/1/2009 and 12/31/2009 who did not receive chlorhexidine mouthwash compared to patients that received prophylactic chlorhexidine mouthwash between 3/1/2010 and 2/28/2011. The primary outcome of the study was rate of probable ventilator-associated pneumonia (VAP) for the pre-chlorhexidine implementation cohort compared to post-implementation, using the 2013 Center for Disease Control definitions. Mechanically ventilated patients with respiratory cultures were screened for inclusion in the study. Secondary endpoints included duration of mechanical ventilation, in-hospital mortality, ICU and hospital length of stay. Statistical analysis was conducted by Fisher's exact test for nominal data and Mann-Whitney U test for continuous data. Results: A total of 1780 mechanically ventilated patients in the pre-chlorhexidine group and 1854 in the post-chlorhexidine group were screened for inclusion. Of the 601 mechanically ventilated patients that were further evaluated for inclusion; 158 patients (26.3%) had positive cultures and were included in the study (94 pre-group and 64 post-group). The rate of probable VAP was significantly decreased in the post-group compared to the pre-group (1.85% pre vs 0.81% post, P = 0.0082). Conclusion: Use of chlorhexidine mouthwash prophylaxis may reduce rates of probable VAP. Further study is warranted. PMID:27051615

    Analysis of indication-related drug prescription patterns is of particular interest with regard to rising costs of the health service being also reflected in higher expenditures for drugs at the University Hospital of the Friedrich-Schiller-University Jena. This is especially important at ICU's, since treatments in patients with acute or chronic multiorgan failure are very expensive. Over a period of 4 months in 1994 the indication-related drug consumption of 2 surgical ICU's of the University of Jena has been recorded and analyzed using a notebook-PC. The total costs of these drugs and blood products, which caused 80% of total costs in the last year, came up to 1,144,773 DM for 465 patients. Nearly two thirds of the recorded expenditures were caused in patients with severe trauma or with acute bleeding. The 10 leading substances (antithrombin III, human albumin 20%, prothrombine complex, etc.) represent 67% of total costs including blood products, antibiotics/antimycotics and IgM enriched intravenous immunoglobulines. Therefore, the indications of these drugs in particular have been further investigated. During and after the study the results have been discussed with the treating medical staff leading to new therapy recommendations. Until the end of 1994 a remarkable cost saving could already be achieved for some drugs by more critical and purposeful use providing same high standard of medical treatment. Blood products have to be included into analyses of indication-related drug administration on the meaning of high costs, difficulties of accurate indication, and possibly undesired side-effects. However, medical and ethical aspects, e.g. minimizing of side-effects, have to take priority over pharmacoeconomical considerations especially in intensive care medicine. PMID:8963483

    This study investigated the ability of adults with Asperger syndrome to recognize emotional categories of facial expressions and emotional prosodies with graded emotional intensities. The individuals with Asperger syndrome showed poorer recognition performance for angry and sad expressions from both facial and vocal information. The group difference in facial expression recognition was prominent for stimuli with low or intermediate emotional intensities. In contrast to this, the individuals with Asperger syndrome exhibited lower recognition accuracy than typically-developed controls mainly for emotional prosody with high emotional intensity. In facial expression recognition, Asperger and control groups showed an inversion effect for all categories. The magnitude of this effect was less in the Asperger group for angry and sad expressions, presumably attributable to reduced recruitment of the configural mode of face processing. The individuals with Asperger syndrome outperformed the control participants in recognizing inverted sad expressions, indicating enhanced processing of local facial information representing sad emotion. These results suggest that the adults with Asperger syndrome rely on modality-specific strategies in emotion recognition from facial expression and prosodic information. PMID:23371506

    This study examined the structure, concurrent validity, and reliability of a hassle measure for middle-aged adults in both event frequency and intensity recordings. The measure included a range of interpersonal day-to-day events and re-examined aspects of the primary appraisal confounding debate between Lazarus and colleagues (Lazarus, Delongis, Folkman, & Gruen, 1985) and Dohrenwend and Shrout (1985). Of the 373 participants, 73% were female, 72% were in paid work, 69% were in permanent relationships and 62% had children. Principal component analyses of separate hassle frequency and intensity scores highlighted components consistent with previous research. There were seven interpersonal and four non-interpersonal subscales associated with negative events with family and friends, work, health, money, and household. The subscales had very good reliability and concurrent validity and there were generally strong correlations (i.e. up .84) between frequency and intensity scores for each subscale. Given some important sampling limitations (e.g. female overrepresentation) the findings show a psychometrically sound hassle scale for adults. PMID:17999222

    Necrotising fasciitis (NF) is a fulminant and life-threatening soft tissue infection, which leads to vascular thrombosis and cutaneous ischemia. We present our experience with extensive necrotising fasciitis in a 4-day-old neonate and stress the importance of early diagnosis, modern dressings including negative pressure therapy, prompt surgical debridement and intensive care to improve the survival and cosmetic outcome of children with NF.

    Inherited hemophagocytic lymphohistiocytosis (HLH) is a genetic anomaly disorder in which abnormally activated cytotoxic T lymphocytes cannot induce the apoptosis of target cells and antigen-presenting cells, leading to hemophagocytosis, pancytopenia, and a variety of symptoms such as a high fever. The present patient with adult-onset HLH developed refractory disease despite receiving immunosuppressive treatments. He underwent a reduced-intensity conditioning (RIC) regimen that comprised antithymocyte globulin (ATG) followed by cord blood transplantation (RIC-CBT). He achieved and maintained a complete donor type. The incorporation of ATG into RIC-CBT may prevent graft failure and control hemophagocytosis, however, further efforts are necessary to reduce infectious complications. PMID:26984088

    An 85-year-old male nursing home resident who is frail but enjoys his current quality of life is admitted with an acute high-grade small bowel obstruction potentially due to adhesions from prior abdominal surgery. The patient has significant tenderness on abdominal exam with involuntary guarding and signs of pneumatosis on the CT scan that are concerning for bowel ischemia. After discussing potential options for management, including surgical intervention and palliative care, the patient and his family express a desire to proceed with surgery because there is a small chance that he could return to his preoperative quality of life. The surgeon believes that his problem is potentially reversible but worries that the patient is at high risk for complications, which could lead to a prolonged ICU stay and subsequent death. How should the possibility of surgical complications be introduced? What plans, if any, should be made at this point for how to deal with complications if one or more occur? PMID:25211275

    Background. High-grade gliomas of the brainstem are rare in adults and are particularly rare in the anterolateral medulla. We describe an illustrative case and discuss the diagnostic and treatment issues associated with a tumor in this location, including differential diagnosis, anatomical considerations for options for surgical management, multimodality treatment, and prognosis. Case Description. A 69-year-old woman presented with a 3-week history of progressive right lower extremity weakness. She underwent an open biopsy via a far lateral approach with partial condylectomy, which revealed a glioblastoma. Concurrent temozolomide and radiation were completed; however, she elected to stop her chemotherapy after 5.5 weeks of treatment. She succumbed to her disease 11 months after diagnosis. Conclusions. Biopsy can be performed relatively safely to provide definitive diagnosis to guide treatment, but long-term prognosis is poor. PMID:27242937

    Introduction The World Health Organization has solicited rapid and minimally invasive techniques to facilitate scale-up of voluntary medical male circumcision (VMMC). Study design Non-blinded randomized controlled field trial with 2:1 allocation ratio. Participants 75 adult male volunteers. Setting Outpatient primary care clinic. Intervention Open surgical circumcision under local anesthetic with suturing vs. Unicirc disposable instrument under topical anesthetic and wound sealing with cyanoacrylate tissue adhesive. Primary Outcome Intraoperative duration. Secondary Outcomes Intraoperative and postoperative pain; adverse events; time to healing; patient satisfaction; cosmetic result. Results The intraoperative time was less with the Unicirc technique (median 12 vs. 25 min, p < 0.001). Wound healing and cosmetic results were superior in the Unicirc group. Adverse events were similar in both groups. Conclusions VMMC with Unicirc under topical anesthetic and wound sealing with cyanoacrylate tissue adhesive is rapid, heals by primary intention with superior cosmetic results, and is potentially safer and more cost-effective than open surgical VMMC. Trial Registration Clinicaltrials.gov NCT02443792 PMID:27299735

    Medulla oblongata (MO) tumors are uncommon in adults. Controversies about their treatment arise regarding the need for histological diagnosis in this eloquent area of the brain, weighing benefits of a reliable diagnosis, and the potential disadvantages of invasive procedures. As a broader variety of pathological findings could be found in this localization, the accurate histopathological definition could not only allow an adequate therapy but also can prevent the disastrous consequences of empiric treatments. There are few publications about their surgical management and all belongs to small retrospective cohorts. In this scenario, we are reporting two patients with exophytic or focal lesions in the inferior half of the medulla, who underwent surgery by suboccipital midline subtonsillar approach. This approach was not specifically described to reach MO before, and we found that the lesions produced a mild elevation of the tonsils providing a wide surgical view from the medulla to the foramen of Luchska laterally, and up to the middle cerebellar peduncle, offering a wide and safe access.

    A substantial portion of patients with obstructive sleep apnea (OSA) seek alternatives to positive airway pressure (PAP), the usual first-line treatment for the disorder. One option is upper airway surgery. As an adjunct to the American Academy of Sleep Medicine (AASM) Standards of Practice paper, we conducted a systematic review and meta-analysis of literature reporting outcomes following various upper airway surgeries for the treatment of OSA in adults, including maxillomandibular advancement (MMA), pharyngeal surgeries such as uvulopharyngopalatoplasty (UPPP), laser assisted uvulopalatoplasty (LAUP), and radiofrequency ablation (RFA), as well as multi-level and multi-phased procedures. We found that the published literature is comprised primarily of case series, with few controlled trials and varying approaches to pre-operative evaluation and post-operative follow-up. We include surgical morbidity and adverse events where reported but these were not systematically analyzed. Utilizing the ratio of means method, we used the change in the apnea-hypopnea index (AHI) as the primary measure of efficacy. Substantial and consistent reductions in the AHI were observed following MMA; adverse events were uncommonly reported. Outcomes following pharyngeal surgeries were less consistent; adverse events were reported more commonly. Papers describing positive outcomes associated with newer pharyngeal techniques and multi-level procedures performed in small samples of patients appear promising. Further research is needed to better clarify patient selection, as well as efficacy and safety of upper airway surgery in those with OSA.

    Background This paper intends to clarify clinical and anatomical features as well as pathological conditions of surgically treated adult patients with occipitalization of the atlas. Methods The authors reviewed 12 consecutive adult patients with occipitalization of the atlas who underwent surgery for myleopathy in our hospital. Mainly using preoperative computed tomography and three-dimensional computed tomography angiography, we investigated their anomalies of the osseous structures and vertebral artery at the cervical spine including the craniovertebral junction (CVJ). We also developed a new classification system for occipitalization of the atlas. Results Atlantoaxial subluxation (AAS) was detected in 9 patients (75%). The condition of AAS was irreducible in 7 patients. Among these 7 patients, deformity at the lateral atlantoaxial joints was detected in 2 patients. C2-3 fusion was detected in 6 patients (67%) among 9 patients with AAS. Anomalies of the VA were detected in 11 patients (92%). Occipitalization of the atlas was classified into three types according to their pathological conditions. In type 1 (2 patients) the medial atlantoaxial joint is semi-dislocated and the lateral atlantoaxial joints are severely deformed. Type 2 (7 patients) exhibits AAS but the lateral atlantoaxial joints are not deformed. Type 3 (3 patients) is not associated with AAS and therefore does not exhibit osseous stenosis at the CVJ. In type 3 the myelopathy was caused by another coexisting condition. Conclusions Occipitalization of the atlas is classified into three types. The main pathological condition in both types 1 and 2 is AAS. Reduction of AAS is essential in both; however, reduction of AAS in type 1 is more technically demanding than in type 2. The pathological conditions of type 3 are completely different from those of the others, so an accurate diagnosis must be made. The new classification system is a useful guide for surgeons when planning surgical strategies. PMID

    According to psychological models as well as common intuition, intense positive and negative situations evoke highly distinct emotional expressions. Nevertheless, recent work has shown that when judging isolated faces, the affective valence of winning and losing professional tennis players is hard to differentiate. However, expressions produced by professional athletes during publicly broadcasted sports events may be strategically controlled. To shed light on this matter we examined if ordinary people's spontaneous facial expressions evoked during highly intense situations are diagnostic for the situational valence. In Experiment 1 we compared reactions with highly intense positive situations (surprise soldier reunions) versus highly intense negative situations (terror attacks). In Experiment 2, we turned to children and compared facial reactions with highly positive situations (e.g., a child receiving a surprise trip to Disneyland) versus highly negative situations (e.g., a child discovering her parents ate up all her Halloween candy). The results demonstrate that facial expressions of both adults and children are often not diagnostic for the valence of the situation. These findings demonstrate the ambiguity of extreme facial expressions and highlight the importance of context in everyday emotion perception. (PsycINFO Database Record PMID:27337681

    This study examined the intensity of activity contributing to physical activity energy expenditure in older adults. In 57 men and women aged ≥ 65, total energy expenditure (TEE) was measured using doubly labeled water and resting metabolic rate was measured using indirect calorimetry to calculate a physical activity index (PAI). Sedentary time and physical activity of light and moderate to vigorous (mod/vig) intensity was measured using an accelerometer. The subjects were 75 ± 7 yrs (mean ± SD) of age and 79% female. Subjects spent 66 ± 8, 25 ± 5, and 9 ± 4% of monitor wear time in sedentary, light, and mod/vig activity per day, respectively. In a mixture regression model, both light (β = 29.6 [15.6-43.6, 95% CI]), p < .001) and mod/vig intensity activity (β = 28.7 [7.4-50.0, 95% CI]), p = .01) were strongly associated with PAI, suggesting that both light and mod/vig intensity activities are major determinants of their physical activity energy expenditure.

    Background: Intradural spinal cord tumors (IDSCTs) in children and young adults are rare diseases. This present study is aimed to demonstrate our experience with a large series of children and young adults with IDSCT. Methods: A total of 50 patients aged <20 years with IDSCT treated in our department between 1990 and 2010 were included in the study. Clinical, histological, and radiological findings, treatment strategies, and clinical outcome were retrospectively assessed. Depending on the relation to the spinal cord, IDSCT were dichotomized into intramedullary SCT (IMSCT) and extramedullary SCT (EMSCT). The functional outcome was evaluated with the Frankel score assessing the longest available follow-up period. Results: Mean age was 10.3 years (range 6 months–19 years). IDSCT surgery was performed in 44 patients (88%). A common first symptom in patients with EMSCT was neck and back pain (41%), whereas monoparesis of arms (43%) were often seen in patients with IMSCT. The main duration of the symptoms was longer in patients with IMSCT. The postoperative functional outcome was generally comparable to the preoperative functional condition, while better for EMSCT (P < 0.01). The functional outcome at last follow-up correlated significantly with the preoperative Frankel score (P < 0.002). Conclusion: Due to the mostly mild impact of the surgery on the functional outcome, the surgical treatment of IDSCT in children and young patients can be uniquely advocated. PMID:26713174

    Radio-tagged adult Pacific lamprey Entosphenus tridentatus held in a raceway with Plexiglas-lined walls and bottom healed more slowly and retained sutures longer than fish held in an all-concrete raceway or one with Plexiglas walls and a cobble-lined bottom. On all substrata, healing depended on when sutures were lost, and fish that lost their sutures in <14 days post-surgery healed faster than those that kept sutures longer. Long-term suture retention led to tissue trauma, infection and poor survival.

    Adult patients presenting with an overcorrected clubfoot often have had a posteromedial release. They present later in life and have compensated quite well despite the development of deformity. Minor trauma may lead to the onset of acute symptoms. A spectrum of deformity exists. Key features include a dorsally subluxated navicular, a dorsal bunion from overpull of the tibialis anterior tendon, valgus of the ankle or hindfoot or both, and a flattop talus. This article details the diagnostic approach to the overcorrected clubfoot patient and options for management of the various components of the deformity. PMID:26589080

    Intestinal failure (IF) is a debilitating condition of inadequate nutrition due to an anatomical and/or physiological deficit of the intestine. Surgical management of patients with acute and chronic IF requires expertise to deal with technical challenges and make correct decisions. Dedicated IF units have expertise in patient selection, operative risk assessment and multidisciplinary support such as nutritional input and interventional radiology, which dramatically improve the morbidity and mortality of this complex condition and can beneficially affect the continuing dependence on parenteral nutritional support. Currently there is little guidance to bridge the gap between general surgeons and specialist IF surgeons. Fifteen European experts took part in a consensus process to develop guidance to support surgeons in the management of patients with IF. Based on a systematic literature review, statements were prepared for a modified Delphi process. The evidence for each statement was graded using Oxford Centre for Evidence-Based Medicine Levels of Evidence. The current paper contains the statements reflecting the position and practice of leading European experts in IF encompassing the general definition of IF surgery and organization of an IF unit, strategies to prevent IF, management of acute IF, management of wound, fistula and stoma, rehabilitation, intestinal and abdominal reconstruction, criteria for referral to a specialist unit and intestinal transplantation.

Case report A case of altered condylar morphology in adult male with temporomandibular disorders was reported in 30-year-old male patient. Erosion and flattening of the left mandibular condyle were observed by panoramic x-ray. The patient was treated with splint therapy that determined mandibular advancement. Eight months after the therapy, reduction in joint pain and a greater opening of the mouth was observed, although crepitation sounds during mastication were still noticeable. Conclusion During the following months of gnatologic treatment, new bone growth in the left condyle was observed by radiograph, with further improvement of the symptoms. PMID:19619334

    Low-intensity physical activity is increasingly promoted as an alternative to sedentary behavior. However, much research to date has focused on moderate- to vigorous-intensity physical activity, and in particular dynamic work, with the effect of low-intensity isometric exercise (<4 METs) on substrate utilization yet to be explored. Here we investigate the effects of such exercise on respiratory quotient (RQ) and determine the extent of intra- and inter-individual variability in response. Energy expenditure, RQ, and substrate oxidation were measured by ventilated-hood indirect calorimetry at rest and in response to standardized, intermittent, low-level isometric leg-press exercises at 5 loads (+5, +10, +15, +20, +25 kg) in 26 healthy, young adults. Nine participants repeated the experiment on 3 separate days to assess within-subject, between-day variability. There was no significant difference in energy cost and heart rate responses to low-intensity isometric exercise (<2 METs) between men and women. However, a sex difference was apparent in terms of substrate oxidation - with men increasing both fat and carbohydrate oxidation, and women only increasing fat oxidation while maintaining carbohydrate oxidation at baseline, resting levels. This sex difference was repeatable and persisted when substrate oxidation was adjusted for differences in body weight or body composition. Individual variability in RQ was relatively low, with both intra- and inter-individual coefficients of variation in the range of 3%-6% in both sexes. These results suggest that women preferentially increase fat oxidation during low-level isometric exercise. Whether such physical activity could be incorporated into treatment/prevention strategies aimed at optimizing fat oxidation in women warrants further investigation. PMID:27540628

    Culture and national care models matter both in reporting and treatment of pain status. However, most findings on body pain intensity and interference in adults are from Western studies, with little reliable evidence from China. This study aimed to assess body pain intensity and interference and its associations with demographic, socioeconomic characteristics, and health behaviors in adults. A cross-sectional survey was performed to collect data from 1224 adults, who were recruited via multistage stratified random sampling. The SF-36 quality-of-life instrument was used to investigate body pain intensity and interference. Ordinal logistic regression analysis was used in this study. Our results showed that 64.1% of the participants (males: 687; females: 537) reported body pain, and 45.7% of the participants reported body pain interference. Middle-aged respondents who were female, were unmarried/divorced or separated/widowed, had a negative relationship with their family, had poor sleep quality, and were not satisfied with their current living conditions had a higher body pain intensity rating (ordered logistic regression/six-level pain intensity criterion; odds ratios, p < 0.05). Respondents who were unmarried/divorced or separated/widowed, with a low education level, were unemployed, had lower incomes, had a negative relationship with their family, and were not satisfied with their current living conditions had a higher body pain interference rating (ordered logistic regression/five-level pain interference criterion; odds ratios, p < 0.05). In conclusion, an estimated 64.1% of middle-aged adults reported body pain, and 45.7% of middle-aged adults reported body pain interference. These results provide a clue for possible interventions for improving body pain intensity and interference in adults, especially among middle-aged people. These factors should be taken into consideration in the prevention of pain, pain management and treatment planning in order to help

    Objective This study aimed to report our experiences with surgical repair in patients of all ages with persistent truncus arteriosus. Methods From July 2004 to July 2014, 50 consecutive patients with persistent truncus arteriosus who underwent anatomical repair were included in the retrospective review. Median follow-up time was 3.4 years (range, 3 months to 10 years). Results Fifty patients underwent anatomical repair at a median age of 19.6 months (range, 20 days to 19.1 years). Thirty patients (60%) were older than one year. The preoperative pulmonary vascular resistance and mean pulmonary artery pressure were 4.1±2.1 (range, 0.1 to 8.9) units.m2 and 64.3±17.9 (range, 38 to 101) mmHg, respectively. Significant truncal valve regurgitation was presented in 14 (28%) patients. Hospital death occurred in 3 patients, two due to pulmonary hypertensive crisis and the other due to pneumonia. Three late deaths occurred at 3, 4 and 11 months after surgery. The actuarial survival rates were 87.7% and 87.7% at 1 year and 5 years, respectively. Multivariate analysis identified significant preoperative truncal valve regurgitation was a risk factor for overall mortality (odds ratio, 7.584; 95%CI: 1.335–43.092; p = 0.022). Two patients required reoperation of truncal valve replacement. One patient underwent reintervention for conduit replacement. Freedom from reoperation at 5 years was 92.9%. At latest examination, there was one patient with moderate-to-severe truncal valve regurgitation and four with moderate. Three patients had residual pulmonary artery hypertension. All survivors were in New York Heart Association class I-II. Conclusions Complete repair of persistent truncus arteriosus can be achieved with a relatively low mortality and acceptable early- and mid-term results, even in cases with late presentation. Significant preoperative truncal valve regurgitation remains a risk factor for overall mortality. The long-term outcomes warrant further follow-up. PMID:26752522

    Background Del Nido (DN) cardioplegic solution (CPS) has been widely used during pediatric cardiac surgery. However, its use in the field of adult cardiac surgery is not popular yet. We evaluated efficacy of DN cardioplegia in adult cardiac surgical patients. Methods Fifty-three adult patients (mean age, 54±16 years) who underwent cardiovascular surgery using DN cardioplegia were enrolled. Myocardial troponin I (TnI) level up to three days after surgery and early clinical outcomes were evaluated. Propensity score matching was performed to compare these results with those after surgery using blood cardioplegia (BC). Results DN cardioplegia was infused with an initial dose of 1,126±221 mL, and an additional 500 mL was reinfused in 15 patients 91 minutes after initial infusion. After release of aortic cross clamp (ACC), spontaneous defibrillation was achieved in 94.3% (50/53). The peak TnI level after surgery was 9.8 ng/mL (range, 2.0–90.2 ng/mL). Linear regression models demonstrated that neither left ventricular mass (LVM) nor ACC time was associated with increased level of peak TnI (P=0.928 and 0.595, respectively). Early mortality occurred in one patient (1.9%). Postoperative complications included atrial fibrillation (n=18, 34.0%), acute kidney injury (n=4, 7.5%), low cardiac output syndrome (n=1, 1.9%), and respiratory complications (n=1, 1.9%). Propensity score matching extracted 39 pairs. Spontaneous defibrillation was achieved more frequently in the DN than BC groups (37/39 vs. 12/39, P<0.001). Peak level and serial changes of TnI were not statistically different between the two groups (P=0.085 and 0.959, respectively). There were also no significant differences in early mortality and postoperative complication rates between the two groups. Conclusions DN cardioplegia is as effective as BC for adult patients in terms of myocardial protection and early clinical outcomes.

There was a significant group × time interaction for change in work capacity (P < 0.001), which increased significantly in CONT (23.8 ± 3.0%) and HIIT (22.3 ± 3.5%) but not PLA (3.1 ± 5.0%). There was a near-significant main effect for percentage trunk fat, with trunk fat reducing in CONT by 3.1 ± 1.6% and in PLA by 1.1 ± 0.4%, but not in HIIT (increase of 0.7 ± 1.0%) (P = 0.07). There was a significant reduction in android fat percentage in CONT (2.7 ± 1.3%) and PLA (1.4 ± 0.8%) but not HIIT (increase of 0.8 ± 0.7%) (P = 0.04). Conclusion. These data suggest that HIIT may be advocated as a time-efficient strategy for eliciting comparable fitness benefits to traditional continuous exercise in inactive, overweight adults. However, in this population HIIT does not confer the same benefit to body fat levels as continuous exercise training. PMID:24669314

    Previous data have shown that high dose of nicotine administration or tobacco smoke exposure can reduce cell formation and the survival rate of adult-born neurons in the dentate gyrus. Here, we subjected adult mice to low intensity cigarette smoke exposure over long time periods. We did a 2×30min/day smoke exposure with two cigarettes per occasion over 1- or 2-months. Subsequently, we carried out a systematic quantitative histopathological analysis to assess the number of newborn neurons in the dentate gyrus. To investigate cell proliferation, the exogenous marker 5-bromo-2'-deoxyuridine (BrdU) was administered on the last experimental day and animals were sacrificed 2h later. To investigate the effect of tobacco smoke on the population of immature neurons, we quantified the number of doublecortin-positive (DCX+) neurons in the same animals. We found that exposing animals to cigarette smoke for 1- or 2-months had no influence on cell proliferation rate, but significantly reduced the number of DCX-positive immature neurons. Our tobacco smoke exposure regimen caused no substantial changes in respiratory functions, but histopathological analysis of the pulmonary tissue revealed a marked perivascular/peribronchial edema formation after 1-month and signs of chronic pulmonary inflammation after 2-months of cigarette smoke exposure. These data demonstrate that even mild exposure to cigarette smoke, without significantly affecting respiratory functions, can have a negative effect on adult-born neurons in the dentate gyrus, when applied over longer time periods. Our data indicate that besides nicotine other factors, such as inflammatory mediators, may also contribute to this effect. PMID:26792108

    Background. Sepsis is a major cause of morbidity and mortality among older adults. The main goals of this study were to assess the association of sepsis at intensive care unit (ICU) admission with mortality and to identify predictors associated with increased mortality in older adults. Methods. We conducted a prospective cohort study of 309 participants ≥60 years admitted to an ICU. Sepsis was defined as 2 of 4 systemic inflammatory response syndrome criteria plus a documented infection within 2 calendar days before or after admission. The main outcome measure was time to death within 1 year of ICU admission. Sepsis was evaluated as a predictor for mortality in a Cox proportional hazards model. Results. Of 309 participants, 196 (63%) met the definition of sepsis. Among those admitted with and without sepsis, 75 (38%) vs 20 (18%) died within 1 month of ICU admission (P < .001) and 117 (60%) vs 48 (42%) died within 1 year (P < .001). When adjusting for baseline characteristics, sepsis had a significant impact on mortality (hazard ratio [HR] = 1.80; 95% confidence interval [CI], 1.28–2.52; P < .001); however, after adjusting for baseline characteristics and process covariates (antimicrobials and vasopressor use within 48 hours of admission), the impact of sepsis on mortality became nonsignificant (HR = 1.26; 95% CI, .87–1.84; P = .22). Conclusions. The diagnosis of sepsis in older adults upon ICU admission was associated with an increase in mortality compared with those admitted without sepsis. After controlling for early use of antimicrobials and vasopressors for treatment, the association of sepsis with mortality was reduced. PMID:26925430

    Objectives This study sought to identify the physical and chemical incompatibilities among the drugs administered intravenously to patients admitted to an adult intensive care unit. We also aimed to establish pharmaceutical guidelines for administering incompatible drugs. Methods This cross-sectional, prospective, and quantitative study was conducted from July to September 2015. Drug incompatibilities were identified based on an analysis of the patient prescriptions available in the hospital online management system. A pharmaceutical intervention was performed using the guidelines on the preparation and administration of incompatible drugs. Adherence to those guidelines was subsequently assessed among the nursing staff. Results A total of 100 prescriptions were analyzed; 68 were incompatible with the intravenous drugs prescribed. A total of 271 drug incompatibilities were found, averaging 4.0 ± 3.3 incompatibilities per prescription. The most commonly found drug incompatibilities were between midazolam and hydrocortisone (8.9%), between cefepime and midazolam (5.2%), and between hydrocortisone and vancomycin (5.2%). The drugs most commonly involved in incompatibilities were midazolam, hydrocortisone, and vancomycin. The most common incompatibilities occurred when a drug was administered via continuous infusion and another was administered intermittently (50%). Of the 68 prescriptions that led to pharmaceutical guidelines, 45 (66.2%) were fully adhered to by the nursing staff. Conclusion Patients under intensive care were subjected to a high rate of incompatibilities. Drug incompatibilities can be identified and eliminated by the pharmacist on the multidisciplinary team, thereby reducing undesirable effects among patients. PMID:27410410

    Twenty-six adults (23 to 58 years) with mild to moderate asthma underwent a 10-week supervised rehabilitation program, with emphasis on physical training. In the first 2 weeks, they exercised daily in an indoor swimming pool (33 degrees C) and received education about asthma, medication, and principles of physical training. In the following 8 weeks, they exercised in the pool twice a week. Every training session lasted 45 min. The training sessions were made as suitable as possible for the individual subjects, in order to minimize "drop outs" from the program. The aim of the study was to evaluate the efficacy of the rehabilitation program and to determine if inactive asthmatic adults can exercise at high intensity. The rehabilitation program was preceded by a 6-min submaximal cycle ergometry test, a 12-min walking test, spirometry, and a methacholine provocation test. The subjects also responded to a five-item questionnaire related to anxiety about exercise, breathlessness, and asthma symptoms using a visual analogue scale. All subjects were able to perform physical training at a very high intensity, to 80 to 90% of their predicted maximal heart rate. No asthmatic attacks occurred in connection with the training sessions. Twenty-two of the 26 subjects completed the rehabilitation program, felt confident with physical training, and planned to continue regular physical training after the 10-week program. Improvements in cardiovascular conditioning, measured as a decreased heart rate at the same load on the cycle ergometer (average of 12 beats/min), and as a longer distance at the 12-min walking test (average of 111 m), were observed during the program. FEV1 increased significantly from 2.2 to 2.5 L. Forced expiratory flow at 25% of vital capacity also increased slightly but significantly. Methacholine provocation dose causing a fall in FEV1 by 20% was unchanged. Seventeen subjects had a peak expiratory flow reduction of more than 15% after the preprogram ergometry

    The aim of this clinical report is to describe the complex treatment of an adult Class III malocclusion patient who was disappointed with the outcome of a previous oral rehabilitation. Interdisciplinary treatment planning was performed with a primary indication for implant removal because of marginal bone loss and gingival recession, followed by orthodontic and surgical procedures to correct the esthetics and skeletal malocclusion. The comprehensive treatment approach included: (1) implant removal in the area of the central incisors; (2) combined orthodontic decompensation with mesial displacement and forced extrusion of the lateral incisors; (3) extraction of the lateral incisors and placement of new implants corresponding to the central incisors, which received provisional crowns; (4) orthognathic surgery for maxillary advancement to improve occlusal and facial relationships; and finally, (5) orthodontic refinement followed by definitive prosthetic rehabilitation of the maxillary central incisors and reshaping of the adjacent teeth. At the three-year follow-up, clinical and radiographic examinations showed successful replacement of the central incisors and improved skeletal and esthetic appearances. Moreover, a Class II molar relationship was obtained with an ideal overbite, overjet, and intercuspation. In conclusion, we report the successful esthetic anterior rehabilitation of a complex case in which interdisciplinary treatment planning improved facial harmony, provided gingival architecture with sufficient width and thickness, and improved smile esthetics, resulting in enhanced patient comfort and satisfaction. This clinical case report might be useful to improve facial esthetics and occlusion in patients with dentoalveolar and skeletal defects. PMID:26877982

    The levels of scattered radiation from 80-kVp and 240-kVp mobile x-ray units were measured in the surgical intensive care unit (ICU). The intensity of scatter of the 240-kVp x rays does not decrease with distance as rapidly as with the 80-kVp beam. In an ICU with four beds, the weekly radiation exposure at the nurses's station approximated 0.05 mR (0.13 x 10/sup -7/ C/kg) for the 80-kVp beam and 0.2 mR (0.52 x 10/sup -7/ C/kg) for the 240-kVp beam. Thus, the annual exposure from either unit would be well below the Maximum Permissible Exposure for nonoccupational workers.

  15. Application of Jean Piaget's theory of human development for nursing children in an adult intensive therapy unit.

    1991-12-01

    Piaget (1964) believed that interaction with the environment has a large part to play in human development. Matthew (1986) states that in an ideal world critically ill children should be cared for by staff trained in paediatrics, within designated paediatric intensive therapy units. Unfortunately, there are only 28 paediatric intensive therapy units in Great Britain (CMA Medical Data, 1987), consequently each year a third of children requiring intensive care are admitted to adult intensive therapy units (ITU). A knowledge and understanding of developmental psychology can therefore be beneficial to nurses in assessing which stage of development a child has reached, in order to plan the correct level of stimulation, and hence facilitate progress rather than regression in the accomplishment of developmental tasks. The psychological and social processes involved in Jean Piaget's (1896-1980) theory of human development are discussed with regard to nursing children requiring intubation and ventilation in an adult ITU.

    Background We sought to reduce local recurrence for retroperitoneal sarcomas by using a coordinated strategy of advanced radiation techniques and aggressive en-bloc surgical resection. Methods Proton-beam radiation therapy (PBRT) and/or intensity-modulated radiation therapy (IMRT) were delivered to improve tumor target coverage and spare selected adjacent organs. Surgical resection of tumor and adjacent organs was performed to obtain a disease-free anterior margin. Intraoperative electron radiation therapy (IOERT) was delivered to any close posterior margin. Results Twenty patients had primary tumors and eight had recurrent tumors. Tumors were large (median size 9.75 cm), primarily liposarcomas and leiomyosarcomas (71%), and were mostly of intermediate or high grade (81%). PBRT and/or IMRT were delivered to all patients, preferably preoperatively (75%), to a median dose of 50 Gy. Surgical resection included up to five adjacent organs, most commonly the colon (n = 7) and kidney (n = 7). Margins were positive for disease, usually posteriorly, in 15 patients (54%). IOERT was delivered to the posterior margin in 12 patients (43%) to a median dose of 11 Gy. Surgical complications occurred in eight patients (28.6%), and radiation-related complications occurred in four patients (14%). After a median follow-up of 33 months, only two patients (10%) with primary disease experienced local recurrence, while three patients (37.5%) with recurrent disease experienced local recurrence. Conclusions Aggressive resection of retroperitoneal sarcomas can achieve a disease-negative anterior margin. PBRT and/or IMRT with IOERT may possibly deliver sufficient radiation dose to the posterior margin to control microscopic residual disease. This strategy may minimize radiation-related morbidity and reduce local recurrence, especially in patients with primary disease. PMID:20151216

    We conducted a quality improvement project in order to evaluate the effect of nurse-to-nurse bedside "rounding" as a strategy to decrease hospital-acquired pressure ulcers (HAPU) in a surgical intensive care unit. We instituted weekly peer-to-peer bedside skin rounds in a 17-bed surgical intensive care unit. Two nurses were identified as skin champions and trained by the hospital's certified WOC nurse to conduct skin rounds. The skin champion nurses conducted weekly peer-to-peer rounds that included discussions about key elements of our patients' skin status including current Braden Scale for Pressure Sore Risk score, and implementation of specific interventions related to subscale risk assessment. If a pressure ulcer was present, the current action plan was reevaluated for effectiveness. Quarterly HAPU prevalence studies were conducted from January 2008 to December 2010. Nineteen patients experienced a HAPU: 17 were located on the coccyx and 2 on the heel. Ten ulcers were classified as stage II, 3 PU were stage IV, 5 were deemed unstageable, and 1 was classified as a deep tissue injury. The frequency of preventive interventions rose during our quality improvement project. Specifically, the use of prevention surfaces increased 92%, repositioning increased 30%, nutrition interventions increased 77%, and moisture management increased 100%. Prior to focused nursing rounds, the highest HAPU prevalence rate was 27%. After implementing focused nursing rounds, HAPU rates trended down and were 0% for 3 consecutive quarters. PMID:22415120

    Acute care of children remains a challenge due to a shortage of pediatric surgeons, particularly in rural areas. In our institutional norm, all cases in patients age six and older are managed by dedicated general surgeons. The provision of care to these children by these surgeons alleviates the impact of such shortages. We conducted a five-year retrospective analysis of all acute care pediatric surgical cases performed in patients aged 6 to 17 years by a dedicated group of adult general surgeons in a rural tertiary care hospital. Demographics, procedure, complications, outcomes, length of stay, and time of consultation/operation were obtained via chart review. Elective, trauma related, or procedures performed by a pediatric surgeon were excluded. Descriptive statistics are reported. A total of 397 cases were performed by six dedicated general surgeons during the study period. Mean age was 11.5 ± 3.1 years. In all, 100 (25.2%) were transferred from outlying facilities and 52.6 per cent of consultations/operations occurred at night (7P-7A), of which 33.2 per cent occurred during late night hours (11P-7A). On weekends, 34.0 per cent occurred. Appendectomy was the most commonly performed operation (n = 357,89.9%), of which 311 were laparoscopic (87.1%). Others included incision/drainage (4.5%), laparoscopic cholecystectomy (2.0%), bowel resection (1.5%), incarcerated hernia (0.5%), small bowel obstruction (0.5%), intra-abdominal abscess drainage (0.3%), resection of intussusception (0.3%), Graham patch (0.3%), and resection omental torsion (0.3%). Median length of stay was two days. Complications occurred in 23 patients (5.8%), of which 22(5.5%) were the result of the disease process. These results parallel those published by pediatric surgeons in this age group and for the diagnoses treated. Models integrating dedicated general surgeons into pediatric call rotations can be designed such that quality of pediatric care is maintained while providing relief to an

    Background: The transport of critically ill patients for procedures or tests outside the Intensive Care Unit (ICU) is potentially hazardous; hence, the transport process must be organized and efficient. Plenty of data is available on pre- and inter-hospital transport of patients; the data on intrahospital transport of patients are limited. We audited the complications and benefits of intrahospital transport of critically ill patients in our tertiary care center over 6 months. Materials and Methods: One hundred and twenty adult critically ill cancer patients transported from the ICU for either diagnostic or therapeutic procedure over 6 months were included. The data collected include the destination, the accompanying person, total time spent outside the ICU, and any adverse events and adverse change in vitals. Results: Among the 120 adult patients, 5 (4.1%) required endotracheal intubation, 5 (4.1%) required intercostal drain placement, and 20 (16.7%) required cardiopulmonary resuscitation (CPR). Dislodgement of central venous catheter occurred in 2 (1.6%) patients, drain came out in 3 (2.5%) patients, orogastric tube came out in 1 (0.8%) patient, 2 (1.6%) patients self-extubated, and in one patient, tracheostomy tube was dislodged. The adverse events were more in patients who spent more than 60 min outside the ICU, particularly requirement of CPR (18 [25%] vs. 2 [4.2%], ≤60 min vs. >60 min, respectively) with P < 0.05. Transport led to change in therapy in 32 (26.7%) patients. Conclusion: Transport in critically ill cancer patients is more hazardous and needs adequate pretransport preparations. Transport in spite being hazardous may lead to a beneficial change in therapy in a significant number of patients.

    This paper explores the challenges surgical practices face in coordinating surgeries and how the electronic surgical record management (ESRM) approach to surgical coordination can solve these problems and improve efficiency. Surgical practices continue to experience costly inefficiencies when managing surgical coordination. Application software like practice management and electronic health record systems have enabled practices to "go digital" for their administrative, financial, and clinical data. However, surgical coordination is still a manual and labor-intensive process. Surgical practices need to create a central and secure record of their surgeries. When surgical data are inputted once only and stored in a central repository, the data are transformed into active information that can be outputted to any form, letter, calendar, or report. ESRM is a new approach to surgical coordination. It enables surgical practices to automate and streamline their processes, reduce costs, and ensure that patients receive the best possible care.

    Background Vietnam is a lower middle-income country with no national surveillance system for hospital-acquired infections (HAIs). We assessed the prevalence of hospital-acquired infections and antimicrobial use in adult intensive care units (ICUs) across Vietnam. Methods Monthly repeated point prevalence surveys were systematically conducted to assess HAI prevalence and antimicrobial use in 15 adult ICUs across Vietnam. Adults admitted to participating ICUs before 08:00 a.m. on the survey day were included. Results Among 3287 patients enrolled, the HAI prevalence was 29.5% (965/3266 patients, 21 missing). Pneumonia accounted for 79.4% (804/1012) of HAIs Most HAIs (84.5% [855/1012]) were acquired in the survey hospital with 42.5% (363/855) acquired prior to ICU admission and 57.5% (492/855) developed during ICU admission. In multivariate analysis, the strongest risk factors for HAI acquired in ICU were: intubation (OR 2.76), urinary catheter (OR 2.12), no involvement of a family member in patient care (OR 1.94), and surgery after admission (OR 1.66). 726 bacterial isolates were cultured from 622/1012 HAIs, most frequently Acinetobacter baumannii (177/726 [24.4%]), Pseudomonas aeruginosa (100/726 [13.8%]), and Klebsiella pneumoniae (84/726 [11.6%]), with carbapenem resistance rates of 89.2%, 55.7%, and 14.9% respectively. Antimicrobials were prescribed for 84.8% (2787/3287) patients, with 73.7% of patients receiving two or more. The most common antimicrobial groups were third generation cephalosporins, fluoroquinolones, and carbapenems (20.1%, 19.4%, and 14.1% of total antimicrobials, respectively). Conclusion A high prevalence of HAIs was observed, mainly caused by Gram-negative bacteria with high carbapenem resistance rates. This in combination with a high rate of antimicrobial use illustrates the urgent need to improve rational antimicrobial use and infection control efforts. PMID:26824228

    Understanding sex differences in the qualitative dimensions of exertional dyspnea may provide insight into why women are more affected by this symptom than men. This study explored the evolution of the qualitative dimensions of dyspnea in 70 healthy, young, physically active adults (35 M and 35 F). Participants rated the intensity of their breathing discomfort (Borg 0-10 scale) and selected phrases that best described their breathing from a standardized list (work/effort, unsatisfied inspiration, and unsatisfied expiration) throughout each stage of a symptom-limited incremental-cycle exercise test. Following exercise, participants selected phrases that described their breathing at maximal exercise from a list of 15 standardized phrases. Intensity of breathing discomfort was significantly higher in women for a given ventilation, but differences disappeared when ventilation was expressed as a percentage of maximum voluntary ventilation. The dominant qualitative descriptor in both sexes throughout exercise was increased work/effort of breathing. At peak exercise, women were significantly more likely to select the following phrases: "my breathing feels shallow," "I cannot get enough air in," "I cannot take a deep breath in," and "my breath does not go in all the way." Women adopted a more rapid and shallow breathing pattern and had significantly higher end-inspiratory lung volumes relative to total lung capacity throughout exercise relative to men. These findings suggest that men and women do not differ in their perceived quality of dyspnea during submaximal exercise, but subjective differences appear at maximal exercise and may be related, at least in part, to underlying sex differences in breathing patterns and operating lung volumes during exercise.

    The Supports Intensity Scale-Adult Version is a standardized assessment of support needs. This study examined the factorial validity of the standardized portion of the scale, finding that the six-factor model (Home Living, Community Living, Lifelong Learning, Employment, Health and Safety, Social Activities) demonstrated good fit, and that the inclusion of the Protection and Advocacy Scale did not affect fit and contributed unique information. Age and gender impacted intensity of support needs, with those of transition age and in late adulthood having the highest intensities. Gender also impacted support needs, but in fewer instances. Implications for future research are discussed. PMID:26701074

    Abstract Atrial septal defect (ASD) closure is major therapy for patients with secundum ASD. Although surgical closure (SC) and transcatheter closure (TC) are usually performed in such patients, data on the long-term outcomes comparing TC and SC in adults are limited. Data on the participants of this cohort study were retrieved from Taiwan's National Health Insurance Research Database from 2004 to 2011. Secundum ASD patients > 18 years of age who underwent TC or SC were initially enrolled, and those with associated comorbidities were excluded. After propensity score matching, the clinical outcomes between the TC and SC groups were analyzed. There were 595 patients recruited in the TC group and 308 patients in the SC group. The SC group had a higher incidence of systemic thromboembolism (P < 0.001), ischemic stroke (P = 0.002), and all-cause mortality (P = 0.013) when compared with those of the TC group at the index hospitalization, and similar phenomena could also be seen in a around 4-year follow-up period after the procedures (systemic thromboembolism (P < 0.001, HR = 11.48, 95% CI: 3.29–40.05), ischemic stroke (P = 0.005, HR = 9.28, 95% CI: 1.94–44.39), and all-cause mortality (P = 0.035, HR = 2.28, 95% CI: 1.06–4.89). In addition, atrial fibrillation (P = 0.005) and atrial flutter (P = 0.049) more frequently developed in the SC group than in the TC group at the index hospitalization. The adult secundum ASD patients had lower incidence rates of systemic thromboembolism, ischemic stroke, and all-cause mortality after TC than those after SC in the 4-year follow-up after procedures. Transcatheter ASD closure should therefore be given priority PMID:26402807

    Background For the Adult Degenerative Scoliosis (ADS) patient with radiculopathy, there is no clear data in the literature to guide the spine surgeon's decision making in choosing between limited decompression alone, short segment fusion, or longer arthrodesis of the deformity. This study investigates the differences in operative planning, for patients with ADS and radiculopathy, between two groups of spine surgeons based on fellowship experience and practice composition. Methods Six Degenerative Spine surgeons (Group 1) and 6 Spinal Deformity surgeons (Group 2) were shown 7 cases of patients with ADS and radiculopathy. Surgeons completed a questionnaire detailing their planned operative intervention including the number of fusion levels, if any, approach, choice of bone graft, and interbody device. Pearson Correlation was used to investigate the association between fellowship training, practice composition, number of levels fused, and other variables. Intraclass correlation (ICC) analysis was used to investigate the internal consistency among the groups. Results There was a direct correlation between fellowship deformity experience and practice composition (r=0.75, p<0.01), and between deformity practice composition and the number of planned fusion levels (r=0.90, p<0.001). Group 1 surgeons fused a mean 3.7 vertebral levels (range 0-6.7), while Group 2 surgeons fused a mean 10.8 levels (range 4-16.5). Group 2 surgeons fused a significantly greater number of levels for each case than degenerative surgeons on paired student t-test (p=0.002). Group 1 surgeons chose decompression alone more commonly than deformity surgeons (p<0.05). Group 2 surgeons had significantly higher group consistency by ICC analysis (p=0.004). Conclusions Fellowship and practice composition influence the physician's surgical planning in ADS. There is a lack of standardized treatment paradigms for the management of radiculopathy in patients with ADS. PMID:26114090

    Background: GlideScope (GS) is a video laryngoscope that allows a real-time view of the glottis and endotracheal intubation. It provides a better view of the larynx without the need for alignment of the airway axes. Aim: This prospective randomized comparative study is designed to compare the intubation time, hemodynamic response, and complications associated with intubation using a GS or Macintosh laryngoscope (ML) in adult subjects undergoing elective surgical procedures. Materials and Methods: Sixty American Society of Anesthesiologists physical status 1–2 patients were included in this prospective randomized comparative study. Patients were randomized to be intubated using either a GS or an ML. The primary outcome measure was the intubation time. The secondary outcome measures were the hemodynamic response to intubation and the incidence of mucosal injury. Statistical Analysis: Mean and standard deviation were calculated for different parameters under the study. The observed results were analyzed using Student's t-test for quantitative data and Z-test of proportions. P<0.05 was considered statistically significant. Results: Intubation time was longer in GS group (45.7033 ± 11.649 s) as compared to ML (27.773 ± 5.122 s) P< 0.0001 with 95% confidence interval (95% CI) −13.2794 to −22.5806. GS provided better Cormack and Lehane laryngoscopic view (P = 0.0016 for grade 1 view) with 95% CI −0.1389 to −0.5951. GS group exhibited more laryngoscopic response than ML group with more increase in blood pressure and heart rate, but the difference was not statistically significant. More cases of mucosal trauma were documented in GS group. Conclusion: Use of GS to facilitate intubation led to better glottic view but took a longer time to achieve endotracheal intubation. GS was associated with more hemodynamic response to intubation and mucosal injury in comparison with an ML. PMID:27212755

    Cannabinoids purportedly improve taste responsiveness and enhance the sensory appeal of foods. These properties and a commonly cited oral drying effect were evaluated in a series of studies with 'light' marijuana users. The first was a double-blind, placebo-controlled, acute oral dosing trial, involving an age and gender stratified sample of 57 adults. An influence of route of drug delivery was explored in another 11 individuals who were administered a single dose orally, sublingually and via cigarette. To explore effects following chronic administration, six additional individuals were dosed twice per day for 3 days orally and by rectal suppository. Taste intensity and hedonic responses for sweet, sour, salty and bitter food stimuli were monitored at baseline, 2, 4 and 6 hours post-dosing in the acute studies, and daily in the chronic study. Stimulated saliva samples were collected at these same times. Salivary flow rate was significantly negatively correlated with plasma drug levels, and reported 'high' 2 and 4 h post-dosing. No effects of the drug were observed on taste responses. Self-reported shifts in taste responsiveness and hedonics may be related to alterations of memory and cognition, rather than gustatory function. PMID:8055263

    The purpose of this study was to measure the effect of action video gaming on central elements of visual attention using Bundesen's (1990) Theory of Visual Attention. To examine the cognitive impact of action video gaming, we tested basic functions of visual attention in 42 young male adults. Participants were divided into three groups depending on the amount of time spent playing action video games: non-players (<2h/month, N=12), casual players (4-8h/month, N=10), and experienced players (>15h/month, N=20). All participants were tested in three tasks which tap central functions of visual attention and short-term memory: a test based on the Theory of Visual Attention (TVA), an enumeration test and finally the Attentional Network Test (ANT). The results show that action video gaming does not seem to impact the capacity of visual short-term memory. However, playing action video games does seem to improve the encoding speed of visual information into visual short-term memory and the improvement does seem to depend on the time devoted to gaming. This suggests that intense action video gaming improves basic attentional functioning and that this improvement generalizes into other activities. The implications of these findings for cognitive rehabilitation training are discussed. PMID:23261420

    To identify predictive factors and mortality of patients with influenza admitted to intensive care units (ICU) we carried out a prospective cohort study of patients hospitalized with laboratory-confirmed influenza in adult ICUs in a network of Canadian hospitals between 2006 and 2012. There were 626 influenza-positive patients admitted to ICUs over the six influenza seasons, representing 17·9% of hospitalized influenza patients, 3·1/10,000 hospital admissions. Variability occurred in admission rate and proportion of hospital influenza patients who were admitted to ICUs (proportion range by year: 11·7-29·4%; 21·3% in the 2009-2010 pandemic). In logistic regression models ICU patients were younger during the pandemic and post-pandemic period, and more likely to be obese than hospital non-ICU patients. Influenza B accounted for 14·2% of all ICU cases and had a similar ICU admission rate as influenza A. Influenza-related mortality was 17·8% in ICU patients compared to 2·0% in non-ICU patients.

    This review summarizes recent epidemiology of Gram-negative infections in selected countries from Latin American and Caribbean adult intensive care units (ICUs). A systematic search of the biomedical literature (PubMed) was performed to identify articles published over the last decade. Where appropriate, data also were collected from the reference list of published articles, health departments of specific countries, and registries. Independent cohort data from all countries (Argentina, Brazil, Chile, Colombia, Cuba, Mexico, Trinidad and Tobago, and Venezuela) signified a high rate of ICU infections (prevalence: Argentina, 24%; Brazil, 57%). Gram-negative pathogens, predominantly Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Escherichia coli, accounted for >50% of ICU infections, which were often complicated by the presence of multidrug-resistant strains and clonal outbreaks. Empirical use of antimicrobial agents was identified as a strong risk factor for resistance development and excessive mortality. Infection control strategies utilizing hygiene measures and antimicrobial stewardship programs reduced the rate of device-associated infections. To mitigate the poor health outcomes associated with infections by multidrug-resistant Gram-negative bacteria, urgent focus must be placed on infection control strategies and local surveillance programs.

    Using remote video auditing (RVA) and real-time feedback, we replicated health care workers hand hygiene in a second intensive care unit. During the first 4 weeks using RVA without feedback, the compliance rate was 30.42%. The rate during the 64-week postfeedback period (initial 16 and 48 weeks maintenance) with RVA and feedback exceeded 80% on average. These data demonstrate that improved hand hygiene was achieved and sustained with the use of RVA and feedback. PMID:23489740

    Objective To determine if the presence of in-hospital substantial acute stress symptoms, as well as substantial depressive or posttraumatic stress disorder (PTSD) symptoms at 3-months post-intensive care unit (ICU), are associated with increased acute care service utilization over the course of the year following medical-surgical ICU admission. Design Longitudinal cohort study. Setting Academic medical center. Patients 150 patients ≥ 18 years old admitted to medical-surgical ICUs for over 24 hours. Measurements and Main Results Participants were interviewed in-hospital to ascertain substantial acute stress symptoms using the PTSD Checklist-civilian version (PCL-C). Substantial depressive and PTSD symptoms were assessed using the Patient Health Questionnaire-9 and the PCL-C respectively at 3 months post-ICU. The number of rehospitalizations and emergency room (ER) visits were ascertained at 3 and 12 months post-ICU using the Cornell Services Index. After adjusting for participant and clinical characteristics, in-hospital substantial acute stress symptoms were independently associated with greater risk of an additional hospitalization (Relative Risk [RR]: 3.00, 95% Confidence Interval [CI]: 1.80, 4.99) over the year post-ICU. Substantial PTSD symptoms at 3 months post-ICU were independently associated with greater risk of an additional ER visit during the subsequent 9 months (RR: 2.29, 95%CI: 1.09, 4.84) even after adjusting for both rehospitalizations and ER visits between the index hospitalization and 3 months post-ICU. Conclusions Post-ICU psychiatric morbidity is associated with increased acute care service utilization during the year after a medical-surgical ICU admission. Early interventions for at-risk ICU survivors may improve longer-term outcomes and reduce subsequent acute care utilization. PMID:25083985

    Objective To determine if a workplace stress-reduction intervention decreases reactivity to stress among personnel exposed to a highly stressful occupational environment. Methods Personnel from a surgical intensive care unit (SICU) were randomized to a stress reduction intervention or a wait-list control group. The 8-week group mindfulness-based intervention (MBI) included mindfulness, gentle yoga and music. Psychological and biological markers of stress were measured one week before and one week after the intervention. Results Levels of salivary α-amylase, an index of sympathetic activation, were significantly decreased between the 1st and 2nd assessments in the intervention group with no changes in the control group. There was a positive correlation between salivary α-amylase levels and burnout scores. Conclusions These data suggest that this type of intervention could not only decrease reactivity to stress, but also decrease the risk of burnout. PMID:25629803

    A female patient 23 years old was admitted to the medical intensive care unit due to sudden loss of consciousness and seizures. At the time of admition observed lack of consciousness, seizures and severe critical condition was observed. Meningitis and septic shock were diagnosed. Based on computed tomography performed on the first day--inflammation of the sinuses soft tissues was diagnosed. Suspected cause of infection was performed 6 weeks earlier surgical correction of the nasal septum. In the next stage of treatment on the seventh day after admission the functional endoscopic sinus surgery was performed. Due to massive tissue hypoperfusion the necrosis in the skin of the lower limbs occurred. Due to the lack of effectiveness antimicrobial therapy use of intravenous ceftaroline was administrated. Effective treatment allowed in day 11 to wean the patient from the ventilator. At the day 26 the patient was transferred to a hospital in the place of residence. PMID:26802691

    As most critically ill or injured patients will require some degree of sedation, the goal of this paper was to comprehensively review the literature associated with use of sedative agents in the intensive care unit (ICU). The first and selected latter portions of this article present a narrative overview of the shifting paradigm in ICU sedation practices, indications for uninterrupted or prolonged ICU sedation, and the pharmacology of sedative agents. In the second portion, we conducted a structured, although not entirely systematic, review of the available evidence associated with use of alternative sedative agents in critically ill or injured adults. Data sources for this review were derived by searching OVID MEDLINE and PubMed from their first available date until May 2012 for relevant randomized controlled trials (RCTs), systematic reviews and/or meta-analyses and economic evaluations. Advances in the technology of mechanical ventilation have permitted clinicians to limit the use of sedation among the critically ill through daily sedative interruptions or other means. These practices have been reported to result in improved mortality, a decreased length of ICU and hospital stay and a lower risk of drug-associated delirium. However, in some cases, prolonged or uninterrupted sedation may still be indicated, such as when patients develop intracranial hypertension following traumatic brain injury. The pharmacokinetics of sedative agents have clinical importance and may be altered by critical illness or injury, co-morbid conditions and/or drug-drug interactions. Although use of validated sedation scales to monitor depth of sedation is likely to reduce adverse events, they have no utility for patients receiving neuromuscular receptor blocking agents. Depth of sedation monitoring devices such as the Bispectral Index (BIS©) also have limitations. Among existing RCTs, no sedative agent has been reported to improve the risk of mortality among the critically ill or

    Aims. High-intensity interval training (HIIT) leads to improvements in various markers of cardiometabolic health but adherence to HIIT following a supervised laboratory intervention has yet to be tested. We compared self-report and objective measures of physical activity after one month of independent exercise in individuals with prediabetes who were randomized to HIIT (n = 15) or traditional moderate-intensity continuous training (MICT, n = 17). Method. After completing 10 sessions of supervised training participants were asked to perform HIIT or MICT three times per week for four weeks. Results. Individuals in HIIT (89 ± 11%) adhered to their prescribed protocol to a greater extent than individuals in MICT (71 ± 31%) as determined by training logs completed over one-month follow-up (P = 0.05, Cohen's d = 0.75). Minutes spent in vigorous physical activity per week measured by accelerometer were higher in HIIT (24 ± 18) as compared to MICT (11 ± 10) at one-month follow-up (P = 0.049, Cohen's d = 0.92). Cardiorespiratory fitness and systolic blood pressure assessed at one-month follow-up were equally improved (P's < 0.05). Conclusions. This study provides preliminary evidence that individuals with prediabetes can adhere to HIIT over the short-term and do so at a level that is greater than MICT. PMID:25918728

  17. Lower survival probabilities for adult Florida manatees in years with intense coastal storms

    The endangered Florida manatee (Trichechus manatus latirostris) inhabits the subtropical waters of the southeastern United States, where hurricanes are a regular occurrence. Using mark-resighting statistical models, we analyzed 19 years of photo-identification data and detected significant annual variation in adult survival for a subpopulation in northwest Florida where human impact is low. That variation coincided with years when intense hurricanes (Category 3 or greater on the Saffir-Simpson Hurricane Scale) and a major winter storm occurred in the northern Gulf of Mexico. Mean survival probability during years with no or low intensity storms was 0.972 (approximate 95% confidence interval = 0.961-0.980) but dropped to 0.936 (0.864-0.971) in 1985 with Hurricanes Elena, Kate, and Juan; to 0.909 (0.837-0.951) in 1993 with the March "Storm of the Century"; and to 0.817 (0.735-0.878) in 1995 with Hurricanes Opal, Erin, and Allison. These drops in survival probability were not catastrophic in magnitude and were detected because of the use of state-of-the-art statistical techniques and the quality of the data. Because individuals of this small population range extensively along the north Gulf coast of Florida, it was possible to resolve storm effects on a regional scale rather than the site-specific local scale common to studies of more sedentary species. This is the first empirical evidence in support of storm effects on manatee survival and suggests a cause-effect relationship. The decreases in survival could be due to direct mortality, indirect mortality, and/or emigration from the region as a consequence of storms. Future impacts to the population by a single catastrophic hurricane, or series of smaller hurricanes, could increase the probability of extinction. With the advent in 1995 of a new 25- to 50-yr cycle of greater hurricane activity, and longer term change possible with global climate change, it becomes all the more important to reduce mortality and injury

    A multi-technique approach to modelling artificially ventilated patients on the adult general intensive care unit (ICU) is proposed. Compartmental modelling techniques were used to describe the mechanical ventilator and the flexible hoses that connect it to the patient. 3D CFD techniques were used to model flow in the major airways and a Windkessel style balloon model was used to model the mechanical properties of the lungs. A multi-compartment model of the lung based on bifurcating tree structures representing the conducting airways and pulmonary circulation allowed lung disease to be modelled in terms of altered V/Q ratios within a lognormal distribution of values and it is from these that gas exchange was determined. A compartmental modelling tool, Bathfp, was used to integrate the different modelling techniques into a single model. The values of key parameters in the model could be obtained from measurements on patients in an ICU whilst a sensitivity analysis showed that the model was insensitive to the value of other parameters within it. Measured and modelled values for arterial blood gases and airflow parameters are compared for 46 ventilator settings obtained from 6 ventilator dependent patients. The results show correlation coefficients of 0.88 and 0.85 for the arterial partial pressures of the O(2) and CO(2), respectively (p<0.01) and of 0.99 and 0.96 for upper airway pressure and tidal volume, respectively (p<0.01). The difference between measured and modelled values was large in physiological terms, suggesting that some optimisation of the model is required. PMID:19699134

    Some controversy still exists over the optimal treatment time and the surgical approach for cervical myelopathy due to ossification of the posterior longitudinal ligament (OPLL). The aim of the current study was first to analyze the effect of intramedullary spinal cord changes in signal intensity (hyperintensity on T2-weighted imaging and hypointensity on T1-weighted imaging) on magnetic resonance imaging (MRI) on surgical opportunity and approach for cervical myelopathy due to OPLL. This was a prospective randomized controlled study. Fifty-six patients with cervical myelopathy due to OPLL were enrolled and assigned to either group A (receiving anterior decompression and fusion, n = 27) or group P (receiving posterior laminectomy, n = 29). All the patients were followed up for an average 20.3 months (12-34 months). The clinical outcomes were assessed by the average operative time, blood loss, Japanese Orthopedic Association (JOA) score, improvement rate (IR) and complication. To determine the relevant statistics, we made two factorial designs and regrouped the data of all patients to group H (with hyperintensity on MRI, n = 31), group L (with hypointensity on MRI, n = 19) and group N (no signal on MRI, n = 25), and then to further six subgroups as well: AH (with hyperintensity on MRI from group A, n = 15), PH (with hyperintensity on MRI from group P, n = 16), AL (with hypointensity on MRI from group A, n = 10), PL (with hypointensity on MRI from group P, n = 9), AN (no signal intensity on MRI from group A, n = 12) and PN (no signal intensity on MRI from group P, n = 13). Both hyperintensity on T2-weighted imaging and hypointensity on T1-weighted imaging had a close relationship with the JOA score and IR. The pre- and postoperative JOA score and postoperative IR of either group H or group L was significantly lower than that of group N (P < 0.05), regardless of whether the patients had received anterior or posterior surgery. On the other hand, both the JOA score and

    We report a comparative analysis of intravascular catheter-related infection before and after routine use of antibiotic-bonded catheters in an intensive care unit. Cefazolin-bonded catheters were placed in patients requiring catheterization for at least 3 days, or with remote infection, standard catheters at other times. One thousand forty-five catheters (259 patients) over 6 months were compared with 801 (236 antibiotic-bonded, 565 standard) catheters (239 patients) the next 6 months. After use of antibiotic-bonded catheters, we found: 1.7% catheters infected versus 3.7% (p = 0.01); catheter-associated bacteremia 0.1% versus 1.3% (p < 0.005); catheter-related infection rate 4.39 versus 10.73 per 1000 patient days (p < 0.005), and 5.06 versus 11.47 per 1000 catheter days (p < 0.01); and cumulative risk of infection decreased (p < 0.005). Antibiotic-bonded catheters were used with more remote infections (52% versus 27%, p < 0.001), had longer indwelling time (4.4 versus 3.1 days, p = 0.0001), and more were inserted over a guide wire (66% vs. 28%, p < 0.001). In conclusion routine use of antibiotic-bonded catheters was associated with a significant reduction in infectious complications. PMID:9572020

    Excessive bleeding and allogeneic transfusion during adult post-cardiotomy venoarterial extracorporeal membrane oxygenation (ECMO) are potentially harmful and expensive. Balancing the inhibition of clotting and distinguishing surgical from non-surgical bleeding in post-operative period is difficult. The sensitivity of coagulation tests including Thromboelastography(®) (TEG) to predict chest tube drainage in the early hours of ECMO was examined with the use of receiver-operating characteristics (ROC). The results are useful to incorporate in clinical evidence-based algorithms to guide management decisions. In the eighth hour of ECMO, 26 of the 53 adult patients (49%) studied were identified as non-bleeders (less than 2.0 mL/kg/h). All had experienced various types of cardiac surgical procedures. Fifty-two percent were female and the group was 54 ± 19 (mean ± 1 SD) years old. The coagulation parameter threshold with the maximum sensitivity and specificity to predict non-bleeding at 8 hours on ECMO was the kaolin plus heparinase TEG maximum amplitude (KH-TEG MA) at a significant ROC threshold (t) > 50 mm. The activated partial thromboplastin time (aPTT) t < 49 seconds, KH-TEG alpha-angle t > 51°, and the kaolin activated clotting time (ACT) t < 148 seconds were sensitive predictors of non-bleeders. The whole-blood KH-TEG MA was superior to the plasma-based aPTT or International Normalization Ratio (INR) to predict bleeding in the eighth hour of ECMO. Using coagulation laboratory thresholds that predict non-bleeding can begin a process of identifying patients earlier that are likely to bleed. Awareness of these parameter thresholds may improve care through patient protection from unnecessary transfusion and prolonging the life of the ECMO circuit. An algorithm incorporating the ROC thresholds was created to help recognize surgical bleeding to minimize unnecessary transfusions. PMID:27578897

    Background: The major goal of non-surgical periodontal therapy is to reduce or eliminate the subgingival pathogenic microbial flora that is known to be associated with volatile sulfur compounds (VSC). Aim: The aim of this study was, therefore, to determine the effect of non-surgical periodontal therapy on the concentration of VSC in mouth air of young adults. Subjects and Methods: Four hundred subjects, grouped into two based on the absence or presence of periodontal diseases, were involved in this study. Basic periodontal examination was used for the grouping. The measurement of the concentration of the VSC in the mouth air of the subjects was done objectively, using the Halimeter, before and after the therapy, and at recall visits 2 weeks and 6 weeks after therapy. Chi-square and Paired t-test were used to find statistical significance. Results: The results revealed that at baseline, 78.7% (48/61) of the subjects who had VSC concentration more than 250 parts per billion (ppb) were from the group with periodontal disease. Immediately after non-surgical periodontal therapy, only 8.5% (17/200) of the subjects with periodontal disease had VSC concentration of more than 250 ppb while all the subjects with no periodontal disease had VSC concentration less than 181 ppb. The same pattern of reduction in the concentration of the VSC and improvement in oral hygiene was also obtained 2 weeks and 6 weeks after therapy. Conclusion: It can be concluded that non-surgical periodontal therapy brought about reduction in the concentration of volatile sulfur compounds in mouth air of young adults. PMID:24116328

    Introduction: Central venous pressure (CVP) measurement is essential in the management of certain clinical situations, including cardiac failure, volume overload and sepsis. CVP measurement requires catheterization of the central vein which is invasive and may lead to complications. The aim of this study was to evaluate the accuracy of measurement of CVP using a new noninvasive method based on near infrared spectroscopy (NIRS) in a group of cardiac surgical Intensive Care Unit (ICU) patients. Methodology: Thirty patients in cardiac surgical ICU were enrolled in the study who had an in situ central venous catheter (CVC). Sixty measurements were recorded in 1 h for each patient. A total of 1800 values were compared between noninvasive CVP (CVPn) obtained from Mespere VENUS 2000 CVP system and invasive CVP (CVPi) obtained from CVC. Results: Strong positive correlation was found between CVPi and CVPn (R = 0.9272, P < 0.0001). Linear regression equation - CVPi = 0.5404 + 0.8875 × CVPn (r2 = 0.86, P < 0.001), Bland–Altman bias plots showed mean difference ± standard deviation and limits of agreement: −0.31 ± 1.36 and − 2.99 to + 2.37 (CVPi–CVPn). Conclusion: Noninvasive assessment of the CVP based on NIRS yields readings consistently close to those measured invasively. CVPn may be a clinically useful substitute for CVPi measurements with an advantage of being simple and continuous. It is a promising tool for early management of acute state wherein knowledge of CVP is helpful. PMID:27397443

    [Purpose] The aim of this study was to examine the relationship between the intensity of physical activity and symptoms of depression. [Subjects and Methods] We analyzed the influence of different intensities of physical activity on depressive symptoms using the data of 12,350 adults over the age of 20 years who had completed the 2011 Korea Health Panel. After controlling for confounding variables, a multivariable logistic regression analysis was conducted to identify the association between the intensity of physical activity and depressive symptoms. [Results] The results showed that vigorous physical activity had a significant effect on depressive symptoms. The incidence of depressive symptoms was 1.487 (95% CI 1.137, 1.943) OR higher among people who did not participate in regular activity than it was among those who took part in regular intense physical activity. [Conclusion] It appears that physical activity affects depressive symptoms, a result which is in agreement with previous studies. However, we also showed a difference in influence according to activity intensity. Thus, the intensity of physical activity should be considered when developing physical activity programs for improving depressive symptoms. PMID:25995596

    Objective Obesity increases cardiovascular disease risk and adversely affects vascular structure and function. Few studies have evaluated the vascular effects of non-surgical weight reduction in the severely obese. We hypothesized that weight loss and improvements in cardiometabolic factors would reduce common carotid artery intima-media thickness (CIMT) and inter-adventitial diameter (AD) in severely obese adults. Methods We performed carotid ultrasound and measured cardiometabolic factors in 90 severely obese participants (body mass index (BMI)≥35 kg/m2, age 30–55) at baseline and 6 months in a randomized clinical trial of dietary intervention with (n=45) or without (n=45) physical activity. Results The achieved weight loss (mean=8%) did not differ significantly by intervention group (P=0.10) and resulted in a 0.07 mm mean decrease in AD (P=0.001). AD change was positively correlated with changes in BMI, waist circumference, abdominal visceral and subcutaneous fat, and body fat mass, and AD decreased more in men (P<0.05 for all). After multivariable adjustment, changes in BMI (P=0.03) and abdominal subcutaneous fat (P=0.04) were significant determinants of AD change. Although CIMT did not decrease significantly overall (−0.008 mm, P=0.16), individuals who lost at least 5% of their body weight experienced a significant mean reduction in CIMT of 0.02 mm (P=0.002). CIMT change was positively correlated with changes in BMI, waist circumference, fat-free mass, leptin, and insulin (P<0.05 for all). After multivariable adjustment, insulin reduction remained a significant determinant of CIMT decrease (P=0.03). Conclusion A6 month intensive behavioral intervention can significantly reverse metabolic and vascular abnormalities in severely obese adults. PMID:22579053

    BACKGROUND Care of critically ill patients in intensive care units (ICUs) often requires potentially invasive or uncomfortable procedures, such as mechanical ventilation (MV). Sedation can alleviate pain and discomfort, provide protection from stressful or harmful events, prevent anxiety and promote sleep. Various sedative agents are available for use in ICUs. In the UK, the most commonly used sedatives are propofol (Diprivan(®), AstraZeneca), benzodiazepines [e.g. midazolam (Hypnovel(®), Roche) and lorazepam (Ativan(®), Pfizer)] and alpha-2 adrenergic receptor agonists [e.g. dexmedetomidine (Dexdor(®), Orion Corporation) and clonidine (Catapres(®), Boehringer Ingelheim)]. Sedative agents vary in onset/duration of effects and in their side effects. The pattern of sedation of alpha-2 agonists is quite different from that of other sedatives in that patients can be aroused readily and their cognitive performance on psychometric tests is usually preserved. Moreover, respiratory depression is less frequent after alpha-2 agonists than after other sedative agents. OBJECTIVES To conduct a systematic review to evaluate the comparative effects of alpha-2 agonists (dexmedetomidine and clonidine) and propofol or benzodiazepines (midazolam and lorazepam) in mechanically ventilated adults admitted to ICUs. DATA SOURCES We searched major electronic databases (e.g. MEDLINE without revisions, MEDLINE In-Process & Other Non-Indexed Citations, EMBASE and Cochrane Central Register of Controlled Trials) from 1999 to 2014. METHODS Evidence was considered from randomised controlled trials (RCTs) comparing dexmedetomidine with clonidine or dexmedetomidine or clonidine with propofol or benzodiazepines such as midazolam, lorazepam and diazepam (Diazemuls(®), Actavis UK Limited). Primary outcomes included mortality, duration of MV, length of ICU stay and adverse events. One reviewer extracted data and assessed the risk of bias of included trials. A second reviewer cross-checked all the

    Because older adults are at high risk for hospitalization and potential decisional incapacity, advance directives are important components of pre-hospital advanced care planning, as they document individual preferences for future medical care. The prevalence of pre-hospital advance directive completion in 450 critically ill older adults requiring mechanical ventilation from two Mid-Atlantic hospitals is described, and demographic and clinical predictors of pre-hospital advance directive completion are explored. The overall advance directive completion rate was 42.4%, with those in older age groups (75 to 84 years and 85 and older) having approximately two times the odds of completion. No significant differences in the likelihood of advance directive completion were noted by sex, race, or admitting diagnosis. The relatively low prevalence of advance directive completion among older adults with critical illness and high mortality rate (24%) suggest a need for greater awareness and education.

    Exercise can have anti-inflammatory effects in obesity, but the optimal type and intensity of exercise are not clear. This study compared short-term high-intensity interval training (HIIT) with moderate-intensity continuous training (MICT) in terms of improvement in cardiorespiratory fitness, markers of inflammation, and glucose control in previously inactive adults at elevated risk of developing type 2 diabetes. Thirty-nine inactive, overweight/obese adults (32 women) were randomly assigned to 10 sessions over 2 wk of progressive HIIT (n = 20, four to ten 1-min sessions at ∼90% peak heart rate, 1-min rest periods) or MICT (n = 19, 20-50 min at ∼65% peak heart rate). Before and 3 days after training, participants performed a peak O2 uptake test, and fasting blood samples were obtained. Both HIIT (1.8 ± 0.4 vs. 1.9 ± 0.4 l/min, pre vs. post) and MICT (1.8 ± 0.5 vs. 1.9 ± 0.5 l/min, pre vs. post) improved peak O2 uptake (P < 0.001) and lowered plasma fructosamine (P < 0.05). Toll-like receptor (TLR) 4 (TLR4) expression was reduced on lymphocytes and monocytes after both HIIT and MICT (P < 0.05) and on neutrophils after MICT (P < 0.01). TLR2 on lymphocytes was reduced after HIIT and MICT (P < 0.05). Plasma inflammatory cytokines were unchanged after training in both groups, but MICT led to a reduction in fasting plasma glucose (P < 0.05, 5.9 ± 1.0 vs. 5.6 ± 1.0 mmol/l, pre vs. post). Ten days of either HIIT or MICT can improve cardiorespiratory fitness and glucose control and lead to reductions in TLR2 and TLR4 expression. MICT, which involved a longer duration of exercise, may be superior for reducing fasting glucose. PMID:26139217

    Ketamine is a unique anesthetic drug that provides analgesia, hypnosis, and amnesia with minimal respiratory and cardiovascular depression. Because of its sympathomimetic properties it would seem to be an excellent choice for patients with depressed ventricular function in cardiac surgery. However, its use has not gained widespread acceptance in adult cardiac surgery patients, perhaps due to its perceived negative psychotropic effects. Despite this limitation, it is receiving renewed interest in the United States as a sedative and analgesic drug for critically ill-patients. In this manuscript, the authors provide an evidence-based clinical review of ketamine use in cardiac surgery patients for intensive care physicians, cardio-thoracic anesthesiologists, and cardio-thoracic surgeons. All MEDLINE indexed clinical trials performed during the last 20 years in adult cardiac surgery patients were included in the review. PMID:25849690

    Purpose: To report the long-term outcome after total body irradiation with intensity-modulating compensators and allogeneic/autologous transplantation, especially in terms of therapy-related toxicity in pediatric and adult cohorts. Methods and Materials: A total of 257 consecutive patients (40 children and 217 adults) have been treated since 1983 with TBI using static intensity-modulated radiotherapy for hematologic malignancies. The total dose of 12 Gy was applied in six fractions within 3 days before allogeneic (n = 174) or autologous (n = 83) transplantation. The median follow-up was 9.2 years. Results: The 5-year overall survival rate was 47.9% (49.8% for the adults and 37.5% for the children, p = 0.171). The 5-year tumor-related mortality rate was 23%, and the 5-year treatment-related mortality rate 29.2% (29.5% in the adults and 27.5% in the pediatric patients). Interstitial pneumonitis developed in 28 (10.9%) of 257 patients and in 12.5% of the pediatric cohort. The interstitial pneumonitis rate was 25% in pediatric patients treated with a 12-Gy lung dose compared with 4.2% for those treated to an 11-Gy lung dose. The overall survival rate stratified by lung dose was 26.7% for 12 Gy and 52.4% for 11 Gy (p = 0.001). The incidence of veno-occlusive disease and cataract was 5.8% and 6.6% in all patients and 12.5% and 15% in the pediatric patients, respectively (p < 0.05). Secondary malignancies were found in 4.3% of all patients, all in the adult cohort at transplantation. Conclusion: Static intensity-modulated total body irradiation with a total dose of 12 Gy before allogeneic/autologous transplantation is a successful treatment with good long-term outcome and acceptable therapy-related toxicities. Constraining the lung dose to 11 Gy substantially lowered the actuarial treatment-related mortality. This effect was especially striking in the pediatric patients.

  17. Surgical Treatment Guidelines for Digital Deformity Associated With Intrinsic Muscle Spasticity (Intrinsic Plus Foot) in Adults With Cerebral Palsy.

    2015-01-01

    Intrinsic plus foot deformity has primarily been associated with cerebral palsy and involves spastic contracture of the intrinsic musculature with resultant toe deformities. Digital deformity is caused by a dynamic imbalance between the intrinsic muscles in the foot and extrinsic muscles in the lower leg. Spastic contracture of the toes frequently involves curling under of the lesser digits or contracture of the hallux into valgus or plantarflexion deformity. Patients often present with associated pressure ulcers, deformed toenails, shoe or brace fitting challenges, and pain with ambulation or transfers. Four different patterns of intrinsic plus foot deformity have been observed by the authors that likely relate to the different patterns of muscle involvement. Case examples are provided of the 4 patterns of intrinsic plus foot deformity observed, including global intrinsic plus lesser toe deformity, isolated intrinsic plus lesser toe deformity, intrinsic plus hallux valgus deformity, and intrinsic plus hallux flexus deformity. These case examples are presented to demonstrate each type of deformity and our approach for surgical management according to the contracture pattern. The surgical approach has typically involved tenotomy, capsulotomy, or isolated joint fusion. The main goals of surgical treatment are to relieve pain and reduce pressure points through digital realignment in an effort to decrease the risk of pressure sores and allow more effective bracing to ultimately improve the patient's mobility.

    In addition to cognitive impairment, young adults with intellectual disabilities (IDs) are also more likely to be in poor health. Exercise may help ameliorate both of these deficits. While the health benefits of exercise are well documented and understood, the cognitive benefits of exercise are emerging. Exercise has been shown to improve the cognitive function of young, old, and diseased populations but few studies have evaluated the effect of exercise training on the cognitive functioning of individuals with IDs. The purpose of this study was to determine the effect of moderate-intensity exercise training on the cognitive function of young adults with IDs. Fourteen students (age, 19.4 ± 1.3 years) with mild to moderate IDs participated in an 8-week comprehensive exercise intervention program based on circuit training, aerobic dancing, and adapted sport activities. Sessions lasted 45 minutes, and intensity was maintained at 60-70% of maximum heart rate (HR(max)). Aerobic fitness was assessed via the Young Men's Christian Association (YMCA) step test, and intellectual functioning was assessed via 3 subtests from the Woodcock-Johnson III Tests of Cognitive Abilities once before and after the intervention. Performance was significantly improved on all 3 cognitive tests (all, p < 0.002). Aerobic fitness also significantly improved (p < 0.002). The mean percent increase in processing speed, a measure taking into account each individual's performance on the 3 subtests, was 103%. The mean individual improvement in aerobic fitness was 17.5%. Moderate-intensity exercise training can yield robust improvements in the cognitive functioning and aerobic fitness of young adults with IDs. These effects support the inclusion of exercise into the lives of young adults with ID to promote their physical and cognitive health. Fourteen students (age, 19.4 ± 1.3 years) with mild to moderate IDs participated in an 8-week comprehensive exercise intervention program based on circuit

    Physiological measures of neural activity in the auditory cortex have revealed plasticity following unilateral deafness. Central projections from the remaining ear reorganize to produce a stronger cortical response than normal. However, little is known about the perceptual consequences of this increase. One possibility is improved sound intensity discrimination. Intensity difference limens were measured in 11 individuals with unilateral deafness that were previously shown to exhibit increased cortical activity to sounds heard by the intact ear. Significantly smaller mean difference limens were observed compared with controls. These results provide evidence of the perceptual consequences of plasticity in humans following unilateral deafness.

    After having experienced more than 2,000 cases of adult living donor liver transplantation (LDLT), we established the concepts of right liver graft standardization. Right liver graft standardization intends to provide hemodynamics-based and regeneration-compliant reconstruction of vascular inflow and outflow. Right liver graft standardization consists of the following components: Right hepatic vein reconstruction includes a combination of caudal-side deep incision and patch venoplasty of the graft right hepatic vein to remove the acute angle between the graft right hepatic vein and the inferior vena cava; middle hepatic vein reconstruction includes interposition of a uniform-shaped conduit with large-sized homologous or prosthetic grafts; if the inferior right hepatic vein is present, its reconstruction includes funneling and unification venoplasty for multiple short hepatic veins; if donor portal vein anomaly is present, its reconstruction includes conjoined unification venoplasty for two or more portal vein orifices. This video clip that shows the surgical technique from bench to reperfusion was a case presentation of adult LDLT using a modified right liver graft from the patient's son. Our intention behind proposing the concept of right liver graft standardization is that it can be universally applicable and may guarantee nearly the same outcomes regardless of the surgeon's experience. We believe that this reconstruction model would be primarily applied to a majority of adult LDLT cases. PMID:27621745

    Non-culture-based diagnostic strategies are needed for diagnosing invasive candidiasis (IC). We evaluated serial serum (1→3)-β-d-glucan (BG) levels in patients in the surgical trauma intensive care unit (SICU) patients with clinical evidence of IC. Serum samples from patients admitted to the SICU for a minimum of 3 days were collected twice weekly and analyzed for BG by using a Fungitell kit with a positive cutoff of ≥ 80 pg/ml. Diagnosis of IC was done using a set of predefined and validated clinical practice-based criteria. A total of 57 patients consented to participate and were enrolled. The median ICU stay was 16 days (range, 3 to 51). A total of 14 of 57 (25%) false positives were observed in the first sample (ICU day 3) and, overall, 73% of the day 3 samples had higher BG levels than subsequent samples. On the date of clinical diagnosis of IC, the sensitivity of a positive BG for identifying invasive candidiasis was 87%, with a 73% specificity. In patients with evidence of IC, the median BG value was significantly higher than those without evidence of IC (171 versus 48 pg/ml, P = 0.02), respectively. In the three patients with proven IC, BG was detected 4 to 8 days prior to diagnosis. BG serum detection may be a useful tool to aid in the early diagnosis of IC in SICU patients, particularly after day 3 and in patients with at least two positive samples drawn several days apart. Elevated BG levels within the first 3 days need to be further characterized. PMID:21048005

    We hypothesized that high-intensity interval training (HIIT) would be more effective than moderate-intensity continuous training (MICT) at improving endothelial function and maximum oxygen uptake (V̇o2 max) in obese adults. Eighteen participants [35.1 ± 8.1 (SD) yr; body mass index = 36.0 ± 5.0 kg/m(2)] were randomized to 8 wk (3 sessions/wk) of either HIIT [10 × 1 min, 90-95% maximum heart rate (HRmax), 1-min active recovery] or MICT (30 min, 70-75% HRmax). Brachial artery flow-mediated dilation (FMD) increased after HIIT (5.13 ± 2.80% vs. 8.98 ± 2.86%, P = 0.02) but not after MICT (5.23 ± 2.82% vs. 3.05 ± 2.76%, P = 0.16). Resting artery diameter increased after MICT (3.68 ± 0.58 mm vs. 3.86 ± 0.58 mm, P = 0.02) but not after HIIT (4.04 ± 0.70 mm vs. 4.09 ± 0.70 mm; P = 0.63). There was a significant (P = 0.02) group × time interaction in low flow-mediated constriction (L-FMC) between MICT (0.63 ± 2.00% vs. -2.79 ± 3.20%; P = 0.03) and HIIT (-1.04 ± 4.09% vs. 1.74 ± 3.46%; P = 0.29). V̇o2 max increased (P < 0.01) similarly after HIIT (2.19 ± 0.65 l/min vs. 2.64 ± 0.88 l/min) and MICT (2.24 ± 0.48 l/min vs. 2.55 ± 0.61 l/min). Biomarkers of cardiovascular risk and endothelial function were unchanged. HIIT and MICT produced different vascular adaptations in obese adults, with HIIT improving FMD and MICT increasing resting artery diameter and enhancing L-FMC. HIIT required 27.5% less total exercise time and ∼25% less energy expenditure than MICT. PMID:27255523

    In this study, we randomly compared high doses of the tyrosine kinase inhibitor imatinib combined with reduced-intensity chemotherapy (arm A) to standard imatinib/hyperCVAD (cyclophosphamide/vincristine/doxorubicin/dexamethasone) therapy (arm B) in 268 adults (median age, 47 years) with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL). The primary objective was the major molecular response (MMolR) rate after cycle 2, patients being then eligible for allogeneic stem cell transplantation (SCT) if they had a donor, or autologous SCT if in MMolR and no donor. With fewer induction deaths, the complete remission (CR) rate was higher in arm A than in arm B (98% vs 91%; P = .006), whereas the MMolR rate was similar in both arms (66% vs 64%). With a median follow-up of 4.8 years, 5-year event-free survival and overall survival (OS) rates were estimated at 37.1% and 45.6%, respectively, without difference between the arms. Allogeneic transplantation was associated with a significant benefit in relapse-free survival (hazard ratio [HR], 0.69; P = .036) and OS (HR, 0.64; P = .02), with initial white blood cell count being the only factor significantly interacting with this SCT effect. In patients achieving MMolR, outcome was similar after autologous and allogeneic transplantation. This study validates an induction regimen combining reduced-intensity chemotherapy and imatinib in Ph+ ALL adult patients and suggests that SCT in first CR is still a good option for Ph+ ALL adult patients.

    Importance Cancer is the leading disease-related cause of death among adolescents and young adults (AYAs), but little is known about the care that AYA patients with cancer receive at the end of life (EOL). Objective To evaluate the intensity of EOL care among AYA cancer patients. Design Cross-sectional study using cancer registry and electronic health record data. Setting Kaiser Permanente Southern California (KSPC), an integrated health care delivery system. Participants 663 AYA patients with either (1) stage I-III cancer and evidence of cancer recurrence or (2) stage IV cancer at diagnosis who received care in KPSC and died in the years 2001–2010. Patients were eligible if they were aged 15–39 at death. Main Outcome Measures Chemotherapy use in the last 14 days of life, intensive care unit (ICU) care in the last 30 days of life, more than one emergency room (ER) visit in the last 30 days of life, hospitalization in the last 30 days of life, and a composite measure of medically intensive EOL care comprising any of the aforementioned measures. Results 11% of patients (72/663) received chemotherapy within 14 days of death. In the last 30 days of life, 22% of patients (144/663) were admitted to the ICU; 22% (147/663) had >1 ER visit; and 62% (413/663) were hospitalized. Overall, 68% (449/663) of subjects received at least one medically intensive EOL care measure. Conclusions and Relevance Most AYA patients receive at least one form of medically intensive EOL care. These findings suggest the need to better understand EOL care preferences and decision-making in this young population. PMID:26181778

    Characterizing Epstein–Barr virus (EBV) dynamics in asymptomatic immunocompetent persons provides a baseline for defining quantitative thresholds associated with EBV disease. Studying latent membrane protein (LMP)-1 sequence variation over time could establish the rates of reactivation and superinfection, and also trace transmission. Twelve asymptomatic adult subjects were evaluated prospectively nine times over 6 months. EBV serum antibodies were measured by enzyme immunoassay. EBV DNA in oral and whole-blood samples was quantitated by real-time (TaqMan) PCR and analyzed for LMP-1 sequence variability. All 11 antibody positive subjects had EBV DNA detected in their oral compartment at least once during the 6-month study. The quantities ranged from 1.70 to 4.91 log10 copies EBV per ml of oral cell pellet. One subject was continuously viremic for 79 days. Overall, EBV DNA was detected in 63 (24%) of 260 samples from 11 antibody-positive subjects and in 0/27 samples from an antibody-negative subject. The quantities in positive samples ranged from 1.7 to 4.9 log10 copies EBV per ml. EBV LMP-1 gene sequence variations in subjects were constant over time regardless of the compartment sampled. Subjects 18–30 years old had EBV DNA detected more frequently than subjects >30 years old (38/108 positive samples versus 25/152; P<0.001). In conclusion, EBV DNA shedding is common in asymptomatic adults. The younger adults shed more frequently, which may reflect a shorter time from their primary EBV infection to sampling. The LMP-1 sequence analysis method employed here could be used to trace person-to-person transmission because patterns remained almost identical over time. PMID:27350880

    To guide family adjustment, an effort was made to facilitate pediatric visitation in an adult intensive care unit (ICU). Goals were to improve customer satisfaction and to raise staff comfort level with child visitation. After implementing an open visitation policy, concerns around pediatric visitation in the ICU remained. Fears centered on risks to both patient and child. Literature was reviewed before a book was written entitled A Visit to the ICU. It contained information about what a child visiting the ICU would see, hear, and feel when visiting a loved one. The book provided reassurance for caregivers and children, informing them about what to expect when visiting. The goal of the book was to provide caregivers with a framework for age-appropriate education. Staff education was provided on developmental stages, including a child's understandings of illness and death. Nursing interventions were reviewed and resources provided. A survey demonstrated that the book increased staff comfort level with children visiting the unit, was a positive tool for patients and families, and eased fears among children while helping to facilitate coping mechanisms. The article will describe the practice change of pediatric visitation in an ICU and how it could be applied to other critical care settings. PMID:22157497

    Background Safe Male Circumcision is a proven approach for partial HIV prevention. Several sub Saharan African countries have plans to reach a prevalence of 80% of their adult males circumcised by 2015. These targets require out of ordinary organization, demand creation, timely execution and perhaps the use of SMC devices. Objective To profile Adverse Events rate and acceptance of PrePex, a non surgical device for adult male circumcision. Methods A prospective study, conducted at International Hospital Kampala, Uganda, between August and October 2012. Ethical approval was obtained from Uganda National Council of Science and Technology. Results Of 1,040 men received to undergo SMC, 678 opted for PrePex, 36 were excluded at an initial physical examination screening. 642 were enrolled and consented, and another 17 were excluded before device placement. 625 underwent the procedure. Average age was 24 years (±7). Twelve moderate AEs occurred among 10 participants 12/625, (1.9%). These were all reversible. Five had device displacement, one had an everted foreskin; five had bleeding after the device was removed and one had voiding difficulties. The majority (279 out of 300) of men interviewed complained of some pain within the week of placement. Mean pain score at device placement (using visual analogue scale) was 0.5, at device removal 4.5 and within 2 min of removal the pain score was 1.4. Over 70% of the devices were placed and removed by non-physician clinicians. Presented with a choice, 60% of men chose PrePex over surgical SMC. Close to 90% would recommend the device to their friends. Odour from the necrotic skin was a concern. Removals done 1–2 days earlier than day 7 were beneficial and conferred no extra risk. Conclusion AEs of a moderate or severe nature associated with PrePex were low and reversible. PrePex is feasible for mass safe male circumcision scaling up. PMID:24489754

    Background The objective of this study (ClinicalTrials.gov: NCT01351506) was to identify the threshold level of fluid accumulation measured by acute body weight (BW) change during the first week in a general surgical intensive care unit (ICU), which is associated with ICU mortality and other adverse outcomes. Methods Four hundred sixty-five patients were prospectively followed for a 28-day period. The maximum BW change threshold during the first week was evaluated by the maximum percentage change in BW from the ICU admission weight (Max%ΔBW). Daily screening of adverse events in the ICU were recorded. The cutoff point of Max%ΔBW on ICU mortality was defined by considering the area under the receiver operating characteristic (ROC) curve, intersection of the sensitivity and specificity, and the Youden Index. Univariable and multivariable regression analyses were used to demonstrate the associations. Statistical significance was defined as P<0.05. Results The appropriate cutoff value of Max%ΔBW threshold was 5%. Regarding the multivariable regression model, in overall patients, the occurrence of the following adverse events (expressed as adjusted odds ratio [95% confidence interval]) were significantly associated with a Max%ΔBW of >5%: ICU mortality (2.38 [1.25–4.54]) (P=0.008), ICU mortality in patients without renal replacement therapy (RRT) (2.47 [1.21–5.06]) (P=0.013), reintubation within 72 hours (2.51 [1.04–6.00]) (P=0.039), RRT requirement (2.67 [1.13–6.33]) (P=0.026), and delirium (1.97 [1.08–3.57]) (P=0.025). Regarding the postoperative subgroup, a Max%ΔBW value of more than 5% was significantly associated with: ICU mortality (3.87 [1.38–10.85]) (P=0.010), ICU mortality in patients without RRT (6.32 [1.85–21.64]) (P=0.003), reintubation within 72 hours (4.44 [1.30–15.16]) (P=0.017), and vasopressor requirement (2.04 [1.04–4.01]) (P=0.037). Conclusion Fluid accumulation, measured as acute BW change of more than the threshold of 5% during

    Background: Walking is one of the most commonly recommended activities for sedentary individuals. When performed at the correct intensity, it can provide cardiovascular, respiratory, metabolic, and other benefits by providing a training effect in addition to reducing the risk of death from cardiovascular diseases and other chronic health conditions. Objectives: The primary aim of this study was to assess whether individuals who practiced regular unsupervised walking carry out the activity safely and with sufficient effort intensity parameters to have a positive physiological (training) effect. The secondary objective was to compare the training heart rate (HR) and the stability of the HR within the ideal range of training between the sexes. Method: Individuals were selected from walking tracks within the city of Belo Horizonte, Brazil. The study included subjects from 40 to 60 years of age who had practiced walking for at least two months prior to the study, walking at least three times a week. Individuals who agreed to participate in the survey were asked to walk 15 minutes at their usual pace with their HR measured every 5 minutes using a heart rate monitor. Their average walking HR was compared to the average training HR based on the formula: (220 - age) × 70 to 80% that would result in a positive physiological training effect. Results: Of the 142 individuals evaluated, 25.4% achieved the average training HR. This result was significantly lower than those who did not achieve the average training HR while walking (p=0.002). There were significant differences between men and women who had reached the training HR (p=0.0001). Conclusion: The authors found that individuals who walk regularly performed outside the range of the ideal HR intensity that would cause a positive physiological effect and therefore would probably not achieve a beneficial training effect while walking.

    Stepping is a convenient form of scalable high-intensity interval training (HIIT) that may lead to health benefits. However, the accurate personalised prescription of stepping is hampered by a lack of evidence on optimal stepping cadences and step heights for various populations. This study examined the acute physiological responses to stepping exercise at various heights and cadences in young (n = 14) and middle-aged (n = 14) females in order to develop an equation that facilitates prescription of stepping at targeted intensities. Participants completed a step test protocol consisting of randomised three-minute bouts at different step cadences (80, 90, 100, 110 steps·min-1) and step heights (17, 25, 30, 34 cm). Aerobic demand and heart rate values were measured throughout. Resting metabolic rate was measured in order to develop female specific metabolic equivalents (METs) for stepping. Results revealed significant differences between age groups for METs and heart rate reserve, and within-group differences for METs, heart rate, and metabolic cost, at different step heights and cadences. At a given step height and cadence, middle-aged females were required to work at an intensity on average 1.9 ± 0.26 METs greater than the younger females. A prescriptive equation was developed to assess energy cost in METs using multilevel regression analysis with factors of step height, step cadence and age. Considering recent evidence supporting accumulated bouts of HIIT exercise for health benefits, this equation, which allows HIIT to be personally prescribed to inactive and sedentary women, has potential impact as a public health exercise prescription tool.

    Purpose. To define the maximally tolerated dose (MTD) of ifosfamide when given with G-CSF on an every other week schedule, and to define the MTD of edatrexate that can be given every two weeks with an intense schedule of ifosfamide. Patients and Methods. Forty-one patients with metastatic or unresectable, locally advanced sarcoma participated in this 2-step phase I trial.The starting dose of ifosfamide was 10 gm/m2 given by continuous intravenous infusion over 4 days every 2 weeks.When the MTD was defined, edatrexate, beginning at a dose of 40 mg/m2 intravenously every 2 weeks was added in subsequent cohorts of patients. Results. Myelosuppression was the most prominent toxicity. Fatigue, nausea, and vomiting were observed in the majority of patients. Ifosfamide 12 gm/m2 given every 2 weeks approached or exceeded the MTD. Edatrexate 100 mg/m2 could be given safety as an intravenous bolus with ifosfamide 10 gm/m2 every 2 weeks. Therapeutic responses were observed in patients with measurable disease. Conclusions. This study demonstrates the feasibility of administering a dose-intense schedule of ifosfamide alone or ifosfamide with edatrexate that might be applied in the adjuvant or neo-adjuvant setting.

    Bariatric surgery is a rapidly growing and dynamic discipline necessitating a specialised anaesthetic approach coordinating high-risk patients with appropriate post-operative intensive care (ICU) support. The relationship between the anaesthetic and ICU utilisation after bariatric surgery is poorly understood. All adult bariatric surgery patients admitted to any ICU over a five-year period between 2007 and 2011 in Western Australia were identified from hospital admission records and cross-referenced against the Western Australian Department of Health Data Linkage Unit database. During the study period 12,062 patients under went bariatric surgery with 581 (4.8%) patients admitted to ICU immediately following surgery. The mean pre-operative ASA score was 3.3 [standard deviation 1.1] with 76.9% of patients were assessed by their anaesthetist for the first time on the day-of-surgery. Blood pathology (75%) and ECG (46.3%) were the most common preoperative investigations. Intra-operatively, 2.1% of patients had a grade 4 intubation with only 3.4% of patients requiring a videoscopic assisted intubation. Despite being deemed at high risk, 23.6% of patients were managed with 20 gauge or smaller intravenous access. Anaesthetic complications were extremely uncommon (0.5% of all bariatric cases) but accounted for 9.7% of all postoperative ICU admissions. Smoking history, but not body-mass-index (P=0.46), was the only significant prognostic factor for respiratory or airway related anaesthetic complications (P=0.012). In summary, the anaesthesia management of bariatric surgery varied widely in Western Australia, with smoking as the only significant preoperative risk factor for respiratory or airway related anaesthesia complications.

    Background Pain is a prominent feature of acute dengue as well as a clinical criterion in World Health Organization guidelines in diagnosing dengue. We conducted a prospective cohort study to compare levels of pain during acute dengue between different ethnicities and dengue severity. Methods Demographic, clinical and laboratory data were collected. Data on self-reported pain was collected using the 11-point Numerical Rating Scale. Generalized structural equation models were built to predict progression to severe disease. Results A total of 499 laboratory confirmed dengue patients were recruited in the Prospective Adult Dengue Study at Tan Tock Seng Hospital, Singapore. We found no statistically significant differences between pain score with age, gender, ethnicity or the presence of co-morbidity. Pain score was not predictive of dengue severity but highly correlated to patients’ day of illness. Prevalence of abdominal pain in our cohort was 19%. There was no difference in abdominal pain score between grades of dengue severity. Conclusion Dengue is a painful disease. Patients suffer more pain at the earlier phase of illness. However, pain score cannot be used to predict a patient’s progression to severe disease. PMID:24788828

    Background Research suggests that interaction between humans and digital environments characterizes a form of companionship in addition to technical convenience. To this effect, humans have attempted to design computer systems able to demonstrably empathize with the human affective experience. Facial electromyography (EMG) is one such technique enabling machines to access to human affective states. Numerous studies have investigated the effects of valence emotions on facial EMG activity captured over the corrugator supercilii (frowning muscle) and zygomaticus major (smiling muscle). The arousal emotion, specifically, has not received much research attention, however. In the present study, we sought to identify intensive valence and arousal affective states via facial EMG activity. Methods Ten blocks of affective pictures were separated into five categories: neutral valence/low arousal (0VLA), positive valence/high arousal (PVHA), negative valence/high arousal (NVHA), positive valence/low arousal (PVLA), and negative valence/low arousal (NVLA), and the ability of each to elicit corresponding valence and arousal affective states was investigated at length. One hundred and thirteen participants were subjected to these stimuli and provided facial EMG. A set of 16 features based on the amplitude, frequency, predictability, and variability of signals was defined and classified using a support vector machine (SVM). Results We observed highly accurate classification rates based on the combined corrugator and zygomaticus EMG, ranging from 75.69% to 100.00% for the baseline and five affective states (0VLA, PVHA, PVLA, NVHA, and NVLA) in all individuals. There were significant differences in classification rate accuracy between senior and young adults, but there was no significant difference between female and male participants. Conclusion Our research provides robust evidences for recognition of intensive valence and arousal affective states in young and senior adults. These

    Aging-related decline in functional mobility is associated with loss of independence. This decline may be mitigated through programs of physical activity. Despite reports of aging-related mobility impairment in middle-aged adults, this age group has been largely overlooked in terms of exercise programs that target functional mobility and the preservation of independence in older age. A method to quantitatively assess changes in functional mobility could direct rehabilitation in a proactive rather than reactive manner. Thirty-three healthy but sedentary middle-aged adults participated in a four week low-volume, vigorous intensity stepping exercise program. Two baseline testing sessions and one post-training testing session were conducted. Functional mobility was assessed using the timed up and go (TUG) test, with its constituent sit-to-walk and walk-to-sit phases examined using a novel inertial sensor-based method. Additionally, semi-tandem balance and knee extensor muscle isometric torque were assessed. Trunk acceleration during walk-to-sit reduced significantly post-training, suggesting altered movement control due to the exercise program. No significant training-induced changes in sit-to-walk acceleration, TUG time, balance or torque were observed. The novel method of functional mobility assessment presented provides a reliable means to quantify subtle changes in mobility during postural transitions. Over time, this exercise program may improve functional mobility. PMID:23568151

    Background. Acceptance of dual kidney transplantation (DKT) has proven difficult, due to surgical complexity and concerns regarding long-term outcomes. We herein present a standard technique for ipsilateral DKT and compare outcomes to single-kidney transplant (SKT) recipients. Methods. A retrospective single-center comparison of DKT and SKT performed between February 2007 and July 2013. Results. Of 516 deceased donor kidney transplants, 29 were DKT and 487 were SKT. Mean follow-up was 43 ± 67 months. DKT recipients were older and more likely than SKT recipients to receive an extended criteria graft (p < 0.001). For DKT versus SKT, the rates of delayed graft function (10.3 versus 9.2%) and acute rejection (20.7 versus 22.4%) were equivalent (p = ns). A higher than expected urologic complication rate in the DKT cohort (14 versus 2%, p < 0.01) was reduced through modification of the ureteral anastomosis. Graft survival was equivalent between DKT and SKT groups (p = ns) with actuarial 3-year DKT patient and graft survivals of 100% and 93%. At 3 years, the groups had similar renal function (p = ns). Conclusions. By utilizing extended criteria donor organs as DKT, the donor pool was enlarged while providing excellent patient and graft survival. The DKT urologic complication rate was reduced by modification of the ureteral anastomosis. PMID:27478630

    Background: Anderson-Hynes dismembered pyeloplasty is the gold standard therapeutic approach to ureteropelvic junction obstruction (UPJO). Use of a drainage method to protect the suture line from leakage is a matter of controversy. Objectives: We have compared the surgical outcome of Anderson-Hynes dismembered pyeloplasty for UPJO repair, with or without internal stenting. Patients and Methods: Eighty-two patients with UPJO were evaluated from 1996 to 2002. Complicated or emergent cases were excluded. Classic standard dismembered pyeloplasty was performed. Internal drainage, with a double j catheter, was performed in several patients, randomly. Another drain was also placed in the retroperitoneal space. The follow-up of patients was planned weekly, with patient visits and urine analysis and intravenous pyelography (IVP) and diethylene-triamine-pentaacetate (DTPA) scan after one month. Results: The study group consisted of 51 male and 31 female patients, who were mostly in the age range of 20 - 40 years. Comparing the two techniques of pyeloplasty with or without internal drainage, there was no significant difference between groups regarding extravasation and anastomosis complications, such as leakage, stenosis, urinoma formation or evidence of obstruction on postoperative IVP or DTPA scan. However, a higher incidence of catheter related urinary symptoms and flank pain was reported among those with internal stent. Conclusions: Pyeloplasty, with adequate spatulation, hemostasis and a watertight anastomosis, represents the mainstay of successful pyeloplasty and there may be no significant benefit for urethral stenting, especially in non-complicated cases.

    Previous studies have shown that blood flow-restricted low-intensity resistance training (BFR-RT) causes muscle hypertrophy while maintaining arterial function in young adults. We examined the effects of BFR-RT on muscle size and arterial stiffness in older adults. Healthy subjects (ages 61-84 years) were divided into BFR-RT (n = 9) or non-training control (CON; n = 10) groups. The BFR-RT group performed 20% and 30%, respectively, of one-repetition maximal (1-RM) knee extension and leg press exercises, 2 days/wk for 12 weeks. The BFR-RT group wore elastic cuffs (120-270 mmHg) on both legs during training. Magnetic resonance imaging-measured muscle cross-sectional area (CSA), 1-RM strength, chair stand (CS) test, and cardio-ankle vascular index testing (CAVI), an index of arterial stiffness, were measured before and 3-5 days after the final training session. Muscle CSA of the quadriceps (8.0%), adductors (6.5%), and gluteus maximus (4.4%), leg extension and leg press 1-RM strength (26.1% and 33.4%), and CS performance (18.3%) improved (P < 0.05) in the BFR-RT group, but not in the CON group. In CAVI testing, there were no changes in both two groups. In conclusion, BFR-RT improves muscle CSA as well as maximal muscle strength, but does not negatively affect arterial stiffness or humeral coagulation factors in older adults. PMID:23730848

    Emerging resistance to antibiotics shows no signs of decline. At the same time, few new antibacterials are being discovered. There is a worldwide recognition regarding the danger of this situation. The urgency of the situation and the conviction that practices should change led the Société de Réanimation de Langue Française (SRLF) and the Société Française d'Anesthésie et de Réanimation (SFAR) to set up a panel of experts from various disciplines. These experts met for the first time at the end of 2012 and have since met regularly to issue the following 67 recommendations, according to the rigorous GRADE methodology. Five fields were explored: i) the link between the resistance of bacteria and the use of antibiotics in intensive care; ii) which microbiological data and how to use them to reduce antibiotic consumption; iii) how should antibiotic therapy be chosen to limit consumption of antibiotics; iv) how can antibiotic administration be optimized; v) review and duration of antibiotic treatments. In each institution, the appropriation of these recommendations should arouse multidisciplinary discussions resulting in better knowledge of local epidemiology, rate of antibiotic use, and finally protocols for improving the stewardship of antibiotics. These efforts should contribute to limit the emergence of resistant bacteria. PMID:26077053

    Acute exercise can positively impact cognition. The present study examined the effect of acute high-intensity aerobic exercise on prefrontal-dependent cognitive performance and brain-derived neurotrophic factor (BDNF). Fifty-eight young adults were randomly assigned to one of two experimental groups: (a) an acute bout of high-intensity exercise (n=29) or (b) a non-exercise control (n=29). Participants in the exercise group improved performance on inhibitory control in Stroop interference and on cognitive flexibility in Trail Making Test (TMT) Part-B compared with participants in the control group and increased BDNF immediately after exercise. There was a significant relationship between BDNF and TMT Part-B on the pre-post change following exercise. These findings provide support for the association between improved prefrontal-dependent cognitive performance and increased BDNF in response to acute exercise. We conclude that the changes in BDNF concentration may be partially responsible for prefrontal-dependent cognitive functioning following an acute bout of exercise. PMID:27450438

    Simple Summary The Animal Welfare Indicators (AWIN) project developed a practical welfare assessment protocol for lactating dairy goats in intensive husbandry systems, using animal-based indicators that cover the whole multidimensional concept of animal welfare. The strict collaboration between scientists and stakeholders resulted in an easy-to-use protocol that provides farmers or veterinarians with comprehensive but clear feedback on the welfare status of the herd in less than three hours. The protocol, which highlights key points and motivates farmers to achieve improvements, has received much attention from interested parties. Abstract Within the European AWIN project, a protocol for assessing dairy goats’ welfare on the farm was developed. Starting from a literature review, a prototype including animal-based indicators covering four welfare principles and 12 welfare criteria was set up. The prototype was tested in 60 farms for validity, reliability, and feasibility. After testing the prototype, a two-level assessment protocol was proposed in order to increase acceptability among stakeholders. The first level offers a more general overview of the welfare status, based on group assessment of a few indicators (e.g., hair coat condition, latency to the first contact test, severe lameness, Qualitative Behavior Assessment), with no or minimal handling of goats and short assessment time required. The second level starts if welfare problems are encountered in the first level and adds a comprehensive and detailed individual evaluation (e.g., Body Condition Score, udder asymmetry, overgrown claws), supported by an effective sampling strategy. The assessment can be carried out using the AWIN Goat app. The app results in a clear visual output, which provides positive feedback on welfare conditions in comparison with a benchmark of a reference population. The protocol may be a valuable tool for both veterinarians and technicians and a self-assessment instrument for

    We randomized 3375 adults with newly diagnosed acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome to test whether increasingly intensive chemotherapies assigned at study-entry and analyzed on an intent-to-treat basis improved outcomes. In total, 1529 subjects <60 years were randomized to receive: (1) a first course of induction therapy with high-dose cytarabine and mitoxantrone (HAM) or with standard-dose cytarabine, daunorubicin and 6-thioguanine (TAD) followed by a second course of HAM; (2) granulocyte-colony stimulating factor (G-CSF) or no G-CSF before induction and consolidation courses; and (3) high-dose therapy and an autotransplant or maintenance chemotherapy. In total, 1846 subjects ⩾60 years were randomized to receive: (1) a first induction course of HAM or TAD and second induction course of HAM (if they had bone marrow blasts ⩾5% after the first course); and (2) G-CSF or no G-CSF as above. Median follow-up was 7.4 years (range, 1 day to 14.7 years). Five-year event-free survivals (EFSs) for subjects receiving a first induction course of HAM vs TAD were 17% (95% confidence interval, 15, 18%) vs 16% (95% confidence interval 14, 18%; P=0.719). Five-year EFSs for subjects randomized to receive or not receive G-CSF were 19% (95% confidence interval 16, 21%) vs 16% (95% confidence interval 14, 19%; P=0.266). Five-year relapse-free survivals (RFSs) for subjects <60 years receiving an autotransplant vs maintenance therapy were 43% (95% confidence interval 40, 47%) vs 40 (95% confidence interval 35, 44%; P=0.535). Many subjects never achieved pre-specified landmarks and consequently did not receive their assigned therapies. These data indicate the limited impact of more intensive therapies on outcomes of adults with AML. Moreover, none of the more intensive therapies we tested improved 5-year EFS, RFS or any other outcomes. PMID:26859081

    Background Neuropathic pain (NeP) can be chronic, debilitating, and can interfere with sleep, functioning, and emotional well being. While there are multiple causes of NeP, few studies have examined the disease burden and treatment patterns associated with post-traumatic/post-surgical (PTPS) NeP. Objective To characterize pain, health status, function, health care resource utilization, lost productivity, and costs among subjects with PTPS NeP in the United States. Methods This observational study enrolled 100 PTPS NeP subjects recruited during routine visits from general practitioner and specialist sites. Subjects completed a one-time questionnaire with validated measures of pain severity and pain interference, health status, sleep, anxiety and depression, productivity, and study-specific items on demographics, employment status, and out-of-pocket expenses. Investigators completed a case report form based on a 6-month retrospective chart review, recording subjects’ clinical characteristics as well as current and previous medications/treatments for NeP. Subjects were stratified into mild, moderate, and severe pain groups. Results Subjects’ demographic characteristics were: mean age of 54.9 years, 53% female, and 22% employed for pay. Mean pain severity score was 5.6 (0–10 scale), with 48% and 35% classified as having moderate and severe pain, respectively. The mean number of comorbidities increased with greater pain severity (P = 0.0009). Patient-reported outcomes were worse among PTPS NeP subjects with more severe pain, including pain interference with function, health state utility, sleep, and depression (P < 0.0001). Eighty-two percent of subjects were prescribed two or more NeP medications. The total mean annualized adjusted direct and indirect costs per subject were $11,846 and $29,617, respectively. Across pain severity levels, differences in annualized adjusted direct and indirect costs were significant (P < 0.0001). Conclusion PTPS NeP subjects

    Twenty-two cholangiograms of adults with congenital dilatation of the common bile duct were studied and analyzed. Diagnosis of this disease was established by endoscopic retrograde cholangiopancreaticography in nine patients, by percutaneous transhepatic cholangiography in two patients, and by operative cholangiography in 11 patients. All patients, except one with Caroli's disease, were classified as type I according to Alonso-Lej. An anomalous junction of the pancreaticobiliary ductal system (AJPBDS) was observed in 15 cases. In nine patients the common bile duct joined the main pancreatic duct, and in the remaining six patients, the pancreatic duct was noted to join the common bile duct. These anomalies are considered to be an important etiologic factor in the development of choledochal dilatation. Total cyst excision and hepaticojejunostomy in a Roux-en-Y fashion is recommended as the procedure of choice in those cases with AJPBDS. This is based on the high incidence of cholangitis and the high propensity to induce malignancy of cystic wall following simple drainage. Images Fig. 2. Fig. 3. Fig. 4. PMID:7055397

    Extracorporeal membrane oxygenation (ECMO) is often applied for acute cardiorespiratory failure. Left ventricular distension can compromise recovery of the failing heart. To overcome this complication, we describe a new technique to decompress the left heart through the insertion of a venting cannula in the pulmonary artery. A 43-year-old woman was connected to ECMO for refractory cardiogenic shock after left pneumonia and severe sepsis. Transesophageal echocardiography (TEE) revealed a large intraventricular clot. A 15F venous cannula was placed percutaneously in the pulmonary artery and connected to the venous limb of the ECMO circuit to decompress the left heart, and to prevent left ventricular ejection and potential embolization. After myocardial recovery, when the thrombus was judged as stable, the patient was weaned, and ECMO was removed on day 16. The patient was discharged from the cardiac surgery intensive care unit on day 30 and subsequently had an uneventful recovery. This new percutaneous approach represent a feasible and effective method to vent the left heart during ECMO, when it becomes necessary to reduce wall tension or to prevent ejection. PMID:21048495

    Although active gaming is popular and can increase energy expenditure in young adults, its efficacy as a prescriptive exercise tool is not well understood. This study aimed to: (a) compare the activity intensities experienced by young adults while playing active tennis gaming with conventional sedentary gaming, tennis game-play, and current activity recommendations for health; and (b) identify changes in activity intensities across playing time. After habitualization, 10 active young adults (age: 20.2 ± 0.4 years; stature: 1.74 ± 0.03 m; body mass: 67.7 ± 3.3 kg) completed 3 experimental trials (sedentary gaming, active tennis gaming, and tennis game-play) on separate days in a randomized order. Heart rate (HR) and metabolic equivalents (METs) were averaged across 5 minutes and 10 minutes intervals, and the entire 20 minutes bout within each condition. Active gaming produced greater intensities across 5-10, 10-15, and 15-20 minutes time intervals compared with sedentary gaming (p < 0.01). Tennis game-play elicited greater HR (67 ± 5% HR(max)) and METs (5.0 ± 0.2) responses than both sedentary (40 ± 2% HR(max), 1.1 ± 0.1 METs) and active gaming (45 ± 2% HR(max), 1.4 ± 0.1 METs) (p < 0.001). Only tennis game-play produced activity intensities meeting current recommendations for health benefit. Lower HR intensities were reached across 0-5 minutes than during later time intervals during active gaming (6%) and tennis game-play (9%) (p < 0.01). Activity intensities elicited by active gaming were greater than sedentary gaming but less than tennis game-play and insufficient to contribute toward promoting and maintaining good health in young adults. These data suggest that active tennis gaming should not be recommended by exercise professionals as a substitute for actual sports participation in young adults. PMID:23238089

    Abstract The study aims to find whether a low intensity lifestyle modification (LILM) program was effective to achieve weight reduction and improves metabolic syndrome in young adults. Our study prospectively enrolled young adults aged 30 to 45 years with metabolic syndrome in northeastern Taiwan from June 1, 2008 to December 31, 2009. The participants in the intervention group attended a LILM program for 6 months, which included 4 interactive group discussion sessions and weekly phone contact with volunteer counselors. Participants in the comparison group, however, attended only 1 noninteractive session on diet and physical activity. The main outcomes measured the weight reduction and prevalence of metabolic syndrome in intervention and comparison groups. Generalized estimating equation modeling was used to analyze the effects at baseline, during the study, and postcompletion of the program. Compared with comparison group, the intervention group showed significantly greater reductions in body weight (−2.95 ± 3.52 vs −0.76 ± 2.76 kg, P < 0.0001) and body mass index (−1.03 ± 1.25 vs −0.30 ± 1.16 kg/m2, P < 0.0001). After adjustment for potential confounders, a modest decrease in body weight resulted in a statistically significant 43.32% resolution in the prevalence of metabolic syndrome in the intervention group compared with 33.64% in the comparison group (P < 0.01). The 6-month LILM program is not only effective in weight reduction but also an efficient intervention tool of metabolic syndrome in a community setting. The program with restricted manpower and limited medical resources can be practically transferred into primary care in rural area. PMID:26039125

    2009-01-01

    Introduction Patients with influenza A (H1N1)v infection have developed rapidly progressive lower respiratory tract disease resulting in respiratory failure. We describe the clinical and epidemiologic characteristics of the first 32 persons reported to be admitted to the intensive care unit (ICU) due to influenza A (H1N1)v infection in Spain. Methods We used medical chart reviews to collect data on ICU adult patients reported in a standardized form. Influenza A (H1N1)v infection was confirmed in specimens using real-time reverse transcriptase-polymerase-chain-reaction (RT PCR) assay. Results Illness onset of the 32 patients occurred between 23 June and 31 July, 2009. The median age was 36 years (IQR = 31 - 52). Ten (31.2%) were obese, 2 (6.3%) pregnant and 16 (50%) had pre-existing medical complications. Twenty-nine (90.6%) had primary viral pneumonitis, 2 (6.3%) exacerbation of structural respiratory disease and 1 (3.1%) secondary bacterial pneumonia. Twenty-four patients (75.0%) developed multiorgan dysfunction, 7 (21.9%) received renal replacement techniques and 24 (75.0%) required mechanical ventilation. Six patients died within 28 days, with two additional late deaths. Oseltamivir administration delay ranged from 2 to 8 days after illness onset, 31.2% received high-dose (300 mg/day), and treatment duration ranged from 5 to 10 days (mean 8.0 ± 3.3). Conclusions Over a 5-week period, influenza A (H1N1)v infection led to ICU admission in 32 adult patients, with frequently observed severe hypoxemia and a relatively high case-fatality rate. Clinicians should be aware of pulmonary complications of influenza A (H1N1)v infection, particularly in pregnant and young obese but previously healthy persons. PMID:19747383

    Objective To derive a clinical decision rule to identify adult emergency department (ED) patients with traumatic intracranial hemorrhage (tICH) who are at low risk for requiring critical care resources during hospitalization. Methods This is a retrospective cohort study of patients (≥18 years) with tICH presenting to the ED. The need for intensive care unit (ICU) admission was defined as the presence of a critical care intervention including: intubation, neurosurgical intervention, blood product transfusion, vasopressor or inotrope administration, invasive monitoring for hemodynamic instability, emergent treatment for arrhythmia, therapeutic angiography, and cardiopulmonary resuscitation. The decision rule was derived using binary recursive partitioning. Results A total of 432 patients were identified (median age 48 years) of which 174 patients (40%) had a critical care intervention. We performed binary recursive partitioning with Classification and Regression Trees (CART) software to develop the clinical decision rule. Patients with a normal mental status (Glasgow Coma Score=15), isolated head injury, and age < 65 were considered low risk for a critical care intervention. The derived rule had a sensitivity of 98% (95% confidence interval [CI] 94–99), a specificity of 50% (95% CI 44–56), a positive predictive value of 57% (95% CI 51–62), and a negative predictive value of 97% (95% CI 93–99). The area under the curve for the decision rule was 0.74 (95% CI 0.70–0.77). Conclusions This clinical decision rule identifies low risk adult ED patients with tICH who do not need ICU admission. Further validation and refinement of these findings would allow for more appropriate ICU resource utilization. PMID:21839444

    Background Alcohol misuse ranks within the top ten health conditions with the highest global burden of disease. Low-intensity, Internet interventions for curbing adult alcohol misuse have been shown effective. Few meta-analyses have been carried out, however, and they have involved small numbers of studies, lacked indicators of drinking within low risk guidelines, and examined the effectiveness of unguided self-help only. We therefore conducted a more thorough meta-analysis that included both guided and unguided interventions. Methods Systematic literature searches were performed up to September 2013. Primary outcome was the mean level of alcohol consumption and drinking within low risk guidelines for alcohol consumption at post-treatment. Findings We selected 16 randomised controlled trials (with 23 comparisons and 5,612 participants) for inclusion. Results, showed a small but significant overall effect size in favour of Internet interventions (g = 0.20, 95% CI: 0.13–0.27, p<.001). Participants in Internet interventions drunk on average 22 grams of ethanol less than controls and were significantly more likely to be adhering to low-risk drinking guidelines at post-treatment (RD 0.13, 95% CI: 0.09–0.17, p<.001). Subgroup analyses revealed no significant differences in potential moderators for the outcome of alcohol consumption, although there was a near-significant difference between comparisons with waitlist control and those with assessment-only or alcohol information control conditions (p = .056). Conclusions Internet interventions are effective in reducing adult alcohol consumption and inducing alcohol users to adhere to guidelines for low-risk drinking. This effect is small but from a public health point of view this may warrant large scale implementation at low cost of Internet interventions for adult alcohol misuse. Moderator analyses with sufficient power are, however, needed in order to assess the robustness of these overall results and to

    This longitudinal study tracked the neuro-cognitive changes associated with second language (L2) grammar learning in adults in order to investigate how L2 processing is shaped by a learner’s first language (L1) background and L2 proficiency. Previous studies using event-related potentials (ERPs) have argued that late L2 learners cannot elicit a P600 in response to L2 grammatical structures that do not exist in the L1 or that are different in the L1 and L2. We tested whether the neuro-cognitive processes underlying this component become available after intensive L2 instruction. Korean- and Chinese late-L2-learners of English were tested at the beginning and end of a 9-week intensive English-L2 course. ERPs were recorded while participants read English sentences containing violations of regular past tense (a grammatical structure that operates differently in Korean and does not exist in Chinese). Whereas no P600 effects were present at the start of instruction, by the end of instruction, significant P600s were observed for both L1 groups. Latency differences in the P600 exhibited by Chinese and Korean speakers may be attributed to differences in L1–L2 reading strategies. Across all participants, larger P600 effects at session 2 were associated with: 1) higher levels of behavioural performance on an online grammaticality judgment task; and 2) with correct, rather than incorrect, behavioural responses. These findings suggest that the neuro-cognitive processes underlying the P600 (e.g., “grammaticalization”) are modulated by individual levels of L2 behavioural performance and learning.

    Interventional studies suggest that changes in physical fitness affect brain function and structure. We studied the influence of high intensity physical exercise on hippocampal volume and metabolism in 17 young healthy male adults during a 6-week exercise program compared with matched controls. We further aimed to relate these changes to hypothesized changes in exercised-induced brain-derived neurotrophic factor (BDNF), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α). We show profound improvement of physical fitness in most subjects and a positive correlation between the degree of fitness improvement and increased BDNF levels. We unexpectedly observed an average volume decrease of about 2%, which was restricted to right hippocampal subfields CA2/3, subiculum, and dentate gyrus and which correlated with fitness improvement and increased BDNF levels negatively. This result indicates that mainly those subjects who did not benefit from the exercise program show decreased hippocampal volume, reduced BDNF levels, and increased TNF-α concentrations. While spectroscopy results do not indicate any neuronal loss (unchanged N-acetylaspartate levels) decreased glutamate-glutamine levels were observed in the right anterior hippocampus in the exercise group only. Responder characteristics need to be studied in more detail. Our results point to an important role of the inflammatory response after exercise on changes in hippocampal structure. PMID:26082010

    The aim of this study was to examine the acute effects of mental work and moderate-intensity physical activity on various components of energy balance in young and healthy adults. With the use of a randomized crossover design, 35 participants aged 24 ± 3 years completed three 45-min conditions, namely, (i) resting in a sitting position (control), (ii) reading and writing (mental work (MW)), and (iii) exercising on a treadmill at 40% of peak oxygen uptake (exercise), followed by an ad libitum lunch. The endpoints were spontaneous energy intake (EI), energy expenditure (EE), appetite sensations, and EI for the remainder of the day. We observed that the energy cost of the control and MW conditions was about the same whereas the exercise condition increased EE to a greater extent in men than women. Exercise induced a decrease in EI relative to EE compared to the control condition that was more pronounced in men than women. However, women tended to increase their energy intake after the MW condition compared to the control one whereas an opposite trend was observed in men. None of the appetite sensation markers differed significantly between both sexes. In conclusion, men and women have specific food intake patterns when submitted to cognitive and physical stimuli.

    Lifestyle interventions have resulted in weight loss or improved physical fitness among individuals with obesity, which may lead to improved physical function. This prospective investigation involved participants in the Action for Health in Diabetes (Look AHEAD) trial who reported knee pain at baseline (n = 2,203). The purposes of this investigation were to determine whether an Intensive Lifestyle Intervention (ILI) condition resulted in improvement in self-reported physical function from baseline to 12 months vs. a Diabetes Support and Education (DSE) condition, and whether changes in weight or fitness mediated the effect of the ILI. Outcome measures included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain, stiffness, and physical function subscales, and WOMAC summary score. ILI participants exhibited greater adjusted mean weight loss (s.e.) vs. DSE participants (−9.02 kg (0.48) vs. −0.78 kg (0.49); P < 0.001)). ILI participants also demonstrated more favorable change in WOMAC summary scores vs. DSE participants (β (s.e.) = −1.81 (0.63); P = 0.004). Multiple regression mediation analyses revealed that weight loss was a mediator of the effect of the ILI intervention on change in WOMAC pain, function, and summary scores (P < 0.001). In separate analyses, increased fitness also mediated the effect of the ILI intervention upon WOMAC summary score (P < 0.001). The ILI condition resulted in significant improvement in physical function among overweight and obese adults with diabetes and knee pain. The ILI condition also resulted in significant weight loss and improved fitness, which are possible mechanisms through which the ILI condition improved physical function. PMID:20559303

    Objective: To evaluate the effectiveness of surgical simulation compared with other methods of surgical training. Summary Background Data: Surgical simulation (with or without computers) is attractive because it avoids the use of patients for skills practice and provides relevant technical training for trainees before they operate on humans. Methods: Studies were identified through searches of MEDLINE, EMBASE, the Cochrane Library, and other databases until April 2005. Included studies must have been randomized controlled trials (RCTs) assessing any training technique using at least some elements of surgical simulation, which reported measures of surgical task performance. Results: Thirty RCTs with 760 participants were able to be included, although the quality of the RCTs was often poor. Computer simulation generally showed better results than no training at all (and than physical trainer/model training in one RCT), but was not convincingly superior to standard training (such as surgical drills) or video simulation (particularly when assessed by operative performance). Video simulation did not show consistently better results than groups with no training at all, and there were not enough data to determine if video simulation was better than standard training or the use of models. Model simulation may have been better than standard training, and cadaver training may have been better than model training. Conclusions: While there may be compelling reasons to reduce reliance on patients, cadavers, and animals for surgical training, none of the methods of simulated training has yet been shown to be better than other forms of surgical training.

    The population health effect and cost-effectiveness of implementing intensive blood pressure goals in high-cardiovascular disease (CVD) risk adults have not been described. Using the CVD Policy Model, CVD events, treatment costs, quality-adjusted life years, and drug and monitoring costs were simulated over 2016 to 2026 for hypertensive patients aged 35 to 74 years. We projected the effectiveness and costs of hypertension treatment according to the 2003 Joint National Committee (JNC)-7 or 2014 JNC8 guidelines, and then for adults aged ≥50 years, we assessed the cost-effectiveness of adding an intensive goal of systolic blood pressure <120 mm Hg for patients with CVD, chronic kidney disease, or 10-year CVD risk ≥15%. Incremental cost-effectiveness ratios <$50 000 per quality-adjusted life years gained were considered cost-effective. JNC7 strategies treat more patients and are more costly to implement compared with JNC8 strategies. Adding intensive systolic blood pressure goals for high-risk patients prevents an estimated 43 000 and 35 000 annual CVD events incremental to JNC8 and JNC7, respectively. Intensive strategies save costs in men and are cost-effective in women compared with JNC8 alone. At a willingness-to-pay threshold of $50 000 per quality-adjusted life years gained, JNC8+intensive had the highest probability of cost-effectiveness in women (82%) and JNC7+intensive the highest probability of cost-effectiveness in men (100%). Assuming higher drug and monitoring costs, adding intensive goals for high-risk patients remained consistently cost-effective in men, but not always in women. Among patients aged 35 to 74 years, adding intensive blood pressure goals for high-risk groups to current national hypertension treatment guidelines prevents additional CVD deaths while saving costs provided that medication costs are controlled.

    Many surgical revolutions distinguish the history and evolution of surgery. They come in different sizes and exert a variable effect on the development and practice of the discipline. As science and technology rapidly evolve, so too does the creation of new paradigms, ideas and innovations or discoveries for the improvement of the surgical sciences. Surgical revolutions are not new, and have existed for centuries even though they have been more frequently recognized since the middle of the 19th century, 20th century and down to the present. Surgical revolutionaries are indispensable in the conception and completion of any surgical revolution. However, scientific and technological advances have supported the culmination of each revolution. PMID:18615311

    Late-life depression and pain more often co-occur than can be explained by chance. Determinants of pain in late-life depression are unknown, even though knowledge on possible determinants of pain in depression is important for clinical practice. Therefore, the objectives of the present study were 1) to describe pain characteristics of depressed older adults and a nondepressed comparison group, and 2) to explore physical, lifestyle, psychological, and social determinants of acute and chronic pain intensity, disability, and multisite pain in depressed older adults. Data from the Netherlands Study of Depression in Older Persons cohort, consisting of 378 depressed persons, diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, 4th edition criteria, and 132 nondepressed persons aged 60 years and older, were used in a cross-sectional design. Pain characteristics were measured by the Chronic Graded Pain Scale. Multiple linear regression analyses were performed to explore the contribution of physical, lifestyle, psychological, and social determinants to outcomes pain intensity, disability, and the number of pain locations. Depressed older adults more often reported chronic pain and experienced their pain as more intense and disabling compared to nondepressed older adults. Adjusted for demographic, physical, and lifestyle characteristics, multinomial logistic regression analyses showed increased odds ratios (OR) for depression in acute pain (OR 3.010; P=0.005) and chronic pain (OR 4.544, P<0.001). In addition, linear regression analyses showed that acute and chronic pain intensity, disability, and multisite pain were associated with several biopsychosocial determinants, of which anxiety was most pronounced. Further research could focus on the temporal relationship between anxiety, late-life depression, and pain. PMID:25072890

    We examined the efficacy of reduced-intensity conditioning (RIC) and compared outcomes of 93 patients older than 16 years after RIC with 1428 patients receiving full-intensity conditioning for allografts using sibling and unrelated donors for Philadelphia-negative acute lymphoblastic leukemia (ALL) in first or second complete remission. RIC conditioning included busulfan 9 mg/kg or less (27), melphalan 150 mg/m2 or less (23), low-dose total body irradiation (TBI; 36), and others (7). The RIC group was older (median 45 vs 28 years, P < .001) and more received peripheral blood grafts (73% vs 43%, P < .001) but had similar other prognostic factors. The RIC versus full-intensity conditioning groups had slightly, but not significantly, less acute grade II-IV graft-versus-host disease (39% vs 46%) and chronic graft-versus-host disease (34% vs 42%), yet similar transplantation-related mortality. RIC led to slightly more relapse (35% vs 26%, P = .08) yet similar age-adjusted survival (38% vs 43%, P = .39). Multivariate analysis showed that conditioning intensity did not affect transplantation-related mortality (P = .92) or relapse risk (P = .14). Multivariate analysis demonstrated significantly improved overall survival with: Karnofsky performance status more than 80, first complete remission, lower white blood count, well-matched unrelated or sibling donors, transplantation since 2001, age younger than 30 years, and conditioning with TBI, but no independent impact of conditioning intensity. RIC merits further investigation in prospective trials of adult ALL. PMID:20404137

    The objective of this study was to describe a hospital cluster of NDM-1-producing Enterobacter cloacae infections observed in the surgical intensive care unit (ICU) of a tertiary-care hospital at Pula, Croatia. NDM-1-producing E. cloacae strains isolated from clinical samples were screened by PCR for the presence of carbapenemases. Genetic relatedness of NDM-1-producing E. cloacae strains was determined by multilocus sequence typing (MLST). During the period October 2013 to April 2014, four patients, with overlapping hospital stay in the surgical ICU, developed severe infections caused by E. cloacae demonstrated to produce carbapenemases. According to MLST, all strains belonged to ST133 and were positive by PCR for the blaNDM-1 carbapenemase gene, for blaCTX-M-15 and blaSHV-12 extended-spectrum β-lactamase (ESBL) genes, and for blaTEM-1 and blaOXA-1 narrow-spectrum β-lactamase genes. They were negative for other carbapenemases genes including blaOXA-48, blaVIM and blaKPC as well as for AmpC and the armA and rmtB aminoglycoside resistance genes. All strains were positive for the HI2 replicon, suggesting that an IncHI2 plasmid is likely the plasmid carrying the blaNDM-1 gene. Infection control measures were implemented after the first case although they were not effective in avoiding spread of this organism to other patients in the surgical ICU. In conclusion, the evolving epidemiology of NDM-producing micro-organisms and the interspecies diffusion of this resistance mechanism to emerging pathogens such as E. cloacae necessitate the setting up of strong and urgent joint measures to control the spread of NDM carbapenemase especially in the ICU setting.

    Exercise training at a variety of intensities increases maximal oxygen uptake (VO2max), the strongest predictor of cardiovascular and all-cause mortality. The purpose of the present study was to perform a systematic review, meta-regression and meta-analysis of available literature to determine if a dose-response relationship exists between exercise intensity and training-induced increases in VO2max in young healthy adults. Twenty-eight studies involving human participants (Mean age: 23±1 yr; Mean VO2max: 3.4±0.8 l·min−1) were included in the meta-regression with exercise training intensity, session dose, baseline VO2max, and total training volume used as covariates. These studies were also divided into 3 tertiles based on intensity (tertile 1: ~60–70%; 2: ~80–92.5%; 3: ~100–250%VO2max), for comparison using separate meta-analyses. The fixed and random effects meta-regression models examining training intensity, session dose, baseline VO2max and total training volume was non-significant (Q4=1.36; p=0.85; R2=0.05). There was no significant difference between tertiles in mean change in VO2max (tertile 1:+0.29±0.15 l/min, ES (effect size) =0.77; 2:+0.26±0.10 l/min, ES=0.68; 3:+0.35±0.17 l/min, ES=0.80), despite significant (p<0.05) reductions in session dose and total training volume as training intensity increased. These data suggest that exercise training intensity has no effect on the magnitude of training-induced increases in maximal oxygen uptake in young healthy human participants, but similar adaptations can be achieved in low training doses at higher exercise intensities than higher training doses of lower intensity (endurance training).

    Acute renal failure (ARF) in critically ill patients is currently very frequent and requires renal replacement therapy (RRT) in many patients. During the last 15 years, several studies have considered important issues regarding the use of RRT in ARF, like the time to initiate the therapy, the dialysis dose, the types of catheter, the choice of technique, and anticoagulation. However, despite an abundant literature, conflicting results do not provide evidence on RRT implementation. We present herein recommendations for the use of RRT in adult and pediatric intensive care developed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system by an expert group of French Intensive Care Society (SRLF), with the participation of the French Society of Anesthesia and Intensive Care (SFAR), the French Group for Pediatric Intensive Care and Emergencies (GFRUP), and the French Dialysis Society (SFD). The recommendations cover 4 fields: criteria for RRT initiation, technical aspects (access routes, membranes, anticoagulation, reverse osmosis water), practical aspects (choice of the method, peritoneal dialysis, dialysis dose, adjustments), and safety (procedures and training, dialysis catheter management, extracorporeal circuit set-up). These recommendations have been designed on a practical point of view to provide guidance for intensivists in their daily practice. PMID:26714808

    Introduction Most data on de-escalation of empirical antimicrobial therapy has focused on ventilator-associated pneumonia. In this retrospective monocentric study, we evaluated de-escalation as part of a global strategy of empiric antibiotherapy management irrespective of the location and the severity of the infection. The goal of this trial was to assess the application of a de-escalation strategy and the impact in terms of re-escalation, recurrent infection and to identify variables associated with de-escalation. Methods All consecutive patients treated with empiric antibiotic therapy and hospitalized in the intensive care unit for at least 72 hours within a period of 16 months were included. We compared the characteristics and outcome of patients who have experienced de-escalation therapy with those who have not. Results A total of 116 patients were studied corresponding to 133 infections. Antibiotic therapy was de-escalated in 60 cases (45%). De-escalation, primarily accomplished by a reduction in the number of antibiotics used, was observed in 52% of severe sepsis or septic shock patients. Adequate empiric antibiotic and use of aminoglycoside were independently linked with de-escalation. De-escalation therapy was associated with a significant reduction of recurrent infection (19% vs 5% P = 0.01). Mortality was not changed by de-escalation. Conclusions As part of a global management of empiric antibiotherapy in an intensive care unit, de-escalation might be safe and feasible in a large proportion of patients. PMID:21167047

    Aging is associated with decreased aerobic fitness and cardiac remodeling leading to increased risk for cardiovascular disease. High-intensity interval training (HIIT) on the treadmill has been reported to be more effective in ameliorating these risk factors compared with moderate-intensity continuous training (MICT) in patients with cardiometabolic disease. In older adults, however, weight-bearing activities are frequently limited due to musculoskeletal and balance problems. The purpose of this study was to examine the feasibility and safety of non-weight-bearing all-extremity HIIT in older adults. In addition, we tested the hypothesis that all-extremity HIIT will be more effective in improving aerobic fitness, cardiac function, and metabolic risk factors compared with all-extremity MICT. Fifty-one healthy sedentary older adults (age: 65±1years) were randomized to HIIT (n=17), MICT (n=18) or non-exercise control (CONT; n=16). HIIT (4×4min 90% of peak heart rate; HRpeak) and isocaloric MICT (70% of HRpeak) were performed on a non-weight-bearing all-extremity ergometer, 4×/week for 8weeks under supervision. All-extremity HIIT was feasible in older adults and resulted in no adverse events. Aerobic fitness (peak oxygen consumption; VO2peak) and ejection fraction (echocardiography) improved by 11% (P<0.0001) and 4% (P=0.001), respectively in HIIT, while no changes were observed in MICT and CONT (P≥0.1). Greater improvements in ejection fraction were associated with greater improvements in VO2peak (r=0.57; P<0.0001). Insulin resistance (homeostatic model assessment) decreased only in HIIT by 26% (P=0.016). Diastolic function, body composition, glucose and lipids were unaffected (P≥0.1). In conclusion, all-extremity HIIT is feasible and safe in older adults. HIIT, but not MICT, improved aerobic fitness, ejection fraction, and insulin resistance. PMID:27346646

    Objectives To determine the prevalence of bodily pain measures (pain intensity and pain interference) in elderly people and their relationship with perceived stress scale (PSS) scores. Design Cross-sectional. Setting Community. Participants A representative community sample of 578 subjects aged 70 and older. Measurements The prevalence of pain intensity and pain interference and their relationship with perceived stress scale scores, demographic factors, past medical history, and neuropsychological testing scores were examined. Pain intensity and pain interference were measured by the SF-36 bodily pain questions. Results The study sample of 578 participants has a mean age of 78.8 years and is 63% female. Bivariate analysis for pain measures showed that higher scores on the perceived stress scale, lower neuropsychological test scores, and medical histories were associated with both pain intensity and interference. Logistic regression showed that higher scores on the perceived stress scale were significantly associated with increased odds of having moderate/severe pain intensity and moderate/severe pain interference (with and without the inclusion of for pain intensity in the models). Conclusion Higher PSS scores are associated with higher levels of pain intensity and pain interference. In this cross-sectional analysis, directionality cannot be determined. As both perceived stress and pain are potentially modifiable risk factors for cognitive decline and other poor health outcomes, future research should address temporality and the benefits of treatment.

    We investigated whether focused low-intensity pulsed ultrasound (FLIPUS) affects extracellular matrix (ECM) production in osteoarthritic (OA) rabbits by decreasing chondrocyte apoptosis and pro-inflammatory mediators. An OA model using New Zealand White rabbits (N = 30) and 30 normal rabbits were randomized into three groups (2-, 4- and 8-wk groups; n = 10 knees each). A knee from each rabbit was randomly selected to receive FLIPUS and the other knee received a sham treatment as a control. Another 30 normal rabbits were blank controls. We measured ECM degradation, joint effusion volume and levels of prostaglandin E2 and nitric oxide. Also, ratios of chondrocyte proliferation and apoptosis were calculated. Compared with sham stimulation, FLIPUS attenuated release of type II collagen and proteoglycans and reduced chondrocyte apoptosis as well as total joint effusion volume and significantly alleviated OA-induced accretion of prostaglandin E2 and nitric oxide in the synovial fluid. FLIPUS application promoted ECM production in OA through down regulation inflammatory mediators, joint effusion volume and chondrocyte apoptosis. PMID:26403700

    Concern exists that youth who spend a lot of time participating in organized out-of-school activities (e.g., sports) are at-risk for poor developmental outcomes. This concern - called the over-scheduling hypothesis - has primarily been assessed in terms of adolescent adjustment. This longitudinal study of a nationally representative sample of 1,115 youth (ages 12-18) assessed long-term relations between intensity of participation during adolescence and adjustment at young adulthood (ages 18-24). Time diaries measured intensity as hours per week of participation. Results showed that, controlling for demographic factors and baseline adjustment, intensity was a significant predictor of positive outcomes (e.g., psychological flourishing, civic engagement, educational attainment) and unrelated to indicators of problematic adjustment (e.g., psychological distress, substance use, antisocial behavior) at young adulthood.

    Multi-family therapy (MFT) has yet to be evaluated in families of adults with anorexia nervosa (AN). The study aims were: (i) assess the feasibility of MFT for AN; and, (ii) assess whether MFT is associated with improved outcomes for families compared with single-family therapy (SFT). Adult patients with AN consecutively referred to an eating disorder treatment program were assigned (non-randomly) to receive eight sessions of SFT or MFT. Assessment occurred pre-therapy, immediately post-therapy, and at 3-month follow-up. A total of 37 female patients (13 SFT, 24 MFT) and 45 family members (16 SFT, 29 MFT) completed treatment. There were significant time effects for patients' BMI, eating disorder-related psychopathology and multiple family outcome measures. There were no differences between MFT and SFT on family outcome measures at end of treatment and 3 months post treatment. MFT is a feasible intervention that can be used in adult intensive treatment for those with AN. PMID:25823423

    Despite the popularity of video games, few studies have been conducted in France on their use. The objective of this study was to gather data from a sample of French video game players to learn more about this population. This approach also aimed to examine whether differences exist between adolescent and adult gamers in terms of their motivations to play and whether this practice met the criteria for problem video game playing. A questionnaire collecting sociodemographic data and assessing the problems associated with the use of video games, as well as motivations to play, was distributed during a video game festival and on the Internet. A total of 778 people responded to the questionnaire. The results showed that there were few differences between adolescent and adult gamers. Both groups had an intense video game habit. The majority of them sometimes had the feeling of losing control of their use and sacrificed other activities to play video games. This last dimension was most frequently cited by adults. The feeling of spending more time playing was most frequently cited by adolescents. Concerning motivations to play, the two groups differed only on the score of the "social" dimension, significantly higher among adolescents. PMID:24457109

    Breast surgical oncology is a defined sub-specialty of general surgery with focus on the surgical management of breast disease and malignancy within a multidisciplinary context. Much of the training of breast surgical oncologists in the United States exists within a fellowship training structure with oversight and approval by the Society of Surgical Oncology (SSO). Rapid continuous changes in breast oncology practice have further substantiated dedicated expertise in breast surgical oncology. Training programs are structured to develop proficiency in fellows for advanced surgical techniques and clinical decision-making as well as exposure to the multidisciplinary aspects of breast cancer management. Components of a successful program include an intense multidisciplinary curriculum, engagement in clinical research and attention to strong mentorship. National curriculum and training requirements as well as supplemental resources assist in standardizing the fellowship experience. As surgical training and the field of breast oncology continues to evolve, so do fellowship training programs to ensure high quality breast surgical oncologists equipped to deliver high quality evidence based patient care while continuing to drive future research and trainee education.

    Our six-week treadmill running training (forced exercise) model has revealed that mild exercise (ME) with an intensity below the lactate threshold (LT) is sufficient to enhance spatial memory, while intense exercise (IE) above the LT negates such benefits. To help understand the unrevealed neuronal and signaling/molecular mechanisms of the intensity-dependent cognitive change, in this rat model, we here investigated plasma corticosterone concentration as a marker of stress, adult hippocampal neurogenesis (AHN) as a potential contributor to this ME-induced spatial memory, and comprehensively delineated the hippocampal transcriptomic profile using a whole-genome DNA microarray analysis approach through comparison with IE. Results showed that only IE had the higher corticosterone concentration than control, and that the less intense exercise (ME) is better suited to improve AHN, especially in regards to the survival and maturation of newborn neurons. DNA microarray analysis using a 4 × 44 K Agilent chip revealed that ME regulated more genes than did IE (ME: 604 genes, IE: 415 genes), and only 41 genes were modified with both exercise intensities. The identified molecular components did not comprise well-known factors related to exercise-induced AHN, such as brain-derived neurotrophic factor. Rather, network analysis of the data using Ingenuity Pathway Analysis algorithms revealed that the ME-influenced genes were principally related to lipid metabolism, protein synthesis and inflammatory response, which are recognized as associated with AHN. In contrast, IE-influenced genes linked to excessive inflammatory immune response, which is a negative regulator of hippocampal neuroadaptation, were identified. Collectively, these results in a treadmill running model demonstrate that long-term ME, but not of IE, with minimizing running stress, has beneficial effects on increasing AHN, and provides an ME-specific gene inventory containing some potential regulators of this

    Aging is associated with a functional decline of the oxidative metabolism due to progressive limitations of both O(2) delivery and utilization. Priming exercise (PE) increases the speed of adjustment of oxidative metabolism during successive moderate-intensity transitions. We tested the hypothesis that such improvement is due to a better matching of O(2) delivery to utilization within the working muscles. In 21 healthy older adults (65.7 ± 5 yr), we measured contemporaneously noninvasive indexes of the overall speed of adjustment of the oxidative metabolism (i.e., pulmonary Vo(2) kinetics), of the bulk O(2) delivery (i.e., cardiac output), and of the rate of muscle deoxygenation (i.e., deoxygenated hemoglobin, HHb) during moderate-intensity step transitions, either with (ModB) or without (ModA) prior PE. The local matching of O(2) delivery to utilization was evaluated by the ΔHHb/ΔVo(2) ratio index. The overall speed of adjustment of the Vo(2) kinetics was significantly increased in ModB compared with ModA (P < 0.05). On the contrary, the kinetics of cardiac output was unaffected by PE. At the muscle level, ModB was associated with a significant reduction of the "overshoot" in the ΔHHb/ΔVo(2) ratio compared with ModA (P < 0.05), suggesting an improved O(2) delivery. Our data are compatible with the hypothesis that, in older adults, PE, prior to moderate-intensity exercise, beneficially affects the speed of adjustment of oxidative metabolism due to an acute improvement of the local matching of O(2) delivery to utilization.

  7. The efficacy of vigorous-intensity exercise as an aid to smoking cessation in adults with elevated anxiety sensitivity: study protocol for a randomized controlled trial

    PubMed Central

    2012-01-01

    Background Although cigarette smoking is a leading cause of death and disability in the United States (US), over 40 million adults in the US currently smoke. Quitting smoking is particularly difficult for smokers with certain types of psychological vulnerability. Researchers have frequently called attention to the relation between smoking and anxiety-related states and disorders, and evidence suggests that panic and related anxiety vulnerability factors, specifically anxiety sensitivity (AS or fear of somatic arousal), negatively impact cessation. Accordingly, there is merit to targeting AS among smokers to improve cessation outcome. Aerobic exercise has emerged as a promising aid for smoking cessation for this high-risk (for relapse) group because exercise can effectively reduce AS and other factors predicting smoking relapse (for example, withdrawal, depressed mood, anxiety), and it has shown initial efficacy for smoking cessation. The current manuscript presents the rationale, study design and procedures, and design considerations of the Smoking Termination Enhancement Project (STEP). Methods STEP is a randomized clinical trial that compares a vigorous-intensity exercise intervention to a health and wellness education intervention as an aid for smoking cessation in adults with elevated AS. One hundred and fifty eligible participants will receive standard treatment (ST) for smoking cessation that includes cognitive behavioral therapy (CBT) and nicotine replacement therapy (NRT). In addition, participants will be randomly assigned to either an exercise intervention (ST+EX) or a health and wellness education intervention (ST+CTRL). Participants in both arms will meet 3 times a week for 15 weeks, receiving CBT once a week for the first 7 weeks, and 3 supervised exercise or health and wellness education sessions (depending on randomization) per week for the full 15-week intervention. Participants will be asked to set a quit date for 6 weeks after the baseline visit

    Central line-associated bloodstream infections (CLABSIs) prolong hospital stays and increase cost, morbidity, and mortality. An intensive care unit (ICU) in a suburban Baltimore hospital reduced CLABSI rates to zero in 2012, by revising central venous access device policies and initiatives, which included a bloodstream infection alert system, bundle compliance monitoring and routine evaluation, and use of positive displacement needleless connectors. The hospital's ICU infection rate decreased from 2.9/1000 central-line days in 2010 to 0.8 by 2011, 0 by 2012, and 0.91 in 2013. The utilization ratio was 0.64 in 2011, 0.60 in 2012, and 0.58 in 2013. CLABSI prevention involves all disciplines and requires staff accountability for patient safety. PMID:26714119

    Although aquatic exercise is considered a potentially effective treatment intervention for people with osteoarthritis (OA), previous research has focused primarily on calisthenics in a shallow pool with the inherent limitations on regulating exercise intensity. The purpose of this study was to quantify the efficacy of a 6-week aquatic treadmill exercise program on measures of pain, balance, function, and mobility. Eighteen participants (age = 64.5 ± 10.2 years) with knee OA completed a non-exercise control period followed by a 6-week exercise period. Outcome measures included visual analog scales for pain, posturography for balance, sit-to-stand test for function, and a 10-m walk test for mobility. The exercise protocol included balance training and high-intensity interval training (HIT) in an aquatic treadmill using water jets to destabilize while standing and achieve high ratings of perceived exertion (14-19) while walking. In comparison with pretests, participants displayed reduced joint pain (pre = 50.3 ± 24.8 mm vs. post = 15.8 ± 10.6 mm), improved balance (equilibrium pre = 66.6 ± 11.0 vs. post = 73.5 ± 7.1), function (rising index pre = 0.49 ± 0.19% vs. post = 0.33 ± 0.11%), and mobility (walk pre = 8.6 ± 1.4 s vs. post = 7.8 ± 1.1 s) after participating in the exercise protocol (p = 0.03-0.001). The same benefits were not observed after the non-exercise control period. Adherence to the exercise protocol was exceptional and no participants reported adverse effects, suggesting that aquatic treadmill exercise that incorporates balance and HIT training was well tolerated by patients with OA and may be effective at managing symptoms of OA.

    The aim of this study was to evaluate the influence of a six-week aerobic training on peripheral blood in adults with Down syndrome. Fifteen men with Down syndrome (average age 22.4 years ± 0.91) with moderate or severe intellectual disability took part in the study. Patients underwent a training program three times a week for six weeks. Venous blood samples of 10 ml were collected from every examined patient, 24 hours before and after the exercise. The blood samples were submitted to hematological examination (hematocrit, fibrinogen, plasma viscosity, red blood cell (RBC) number, RBC indicators: mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular hemoglobin (MCH)), reduced glutathione (GSH) level and number of macrocytes, polikilocytrometric examination of RBC and rheological blood examination (elongation index (EI), aggregation index (AI), syllectogram amplitude (AMP), aggregation half time (t1/2)) was made by LORCA. Amoderate six-week physical training performed on a cycloergometer resulted in a statistically significant decrease in the MCV value, hematocrit and plasma viscosity. The six-week cycloergometer training caused a statistically significant increase in the GSH level and erythrocyte pliability at a shear stress of 0.58 Pa. PMID:25371533

    The objective of this study was to assess the impact of the exposure duration and intensity on the human kinetic adjustment factor (HKAF). A physiologically based pharmacokinetic model was used to compute target dose metrics (i.e. maximum blood concentration (C(max)) and amount metabolized/L liver/24  h (Amet)) in adults, neonates (0-30 days), toddlers (1-3 years), and pregnant women following inhalation exposure to benzene, styrene, 1,1,1-trichloroethane and 1,4-dioxane. Exposure scenarios simulated involved various concentrations based on the chemical's reference concentration (low) and six of U.S. EPA's Acute Exposure Guideline Levels (AEGLs) (high), for durations of 10  min, 60  min, 8  h, and 24  h, as well as at steady-state. Distributions for body weight (BW), height (H), and hepatic CYP2E1 content were obtained from the literature or from P3M software, whereas blood flows and tissue volumes were calculated from BW and H. The HKAF was computed based on distributions of dose metrics obtained by Monte Carlo simulations [95th percentile in each subpopulation/median in adults]. At low levels of exposure, ranges of C(max)-based HKAF were 1-6.8 depending on the chemical, with 1,4-dioxane exhibiting the greatest values. At high levels of exposure, this range was 1.1-5.2, with styrene exhibiting the greatest value. Neonates were always the most sensitive subpopulation based on C(max), and pregnant women were most sensitive based on Amet in the majority of the cases (1.3-2.1). These results have shown that the chemical-specific HKAF varies as a function of exposure duration and intensity of inhalation exposures, and sometimes exceeds the default value used in risk assessments.

    This study examined the effects of low-impact, moderate-intensity exercise training with and without wrist weights (0.68 kg.wrist-1) on functional capacities and mood states in older adults (age 68.6 +/- 5.6, mean +/- SD). Twenty-three senior citizens residing in the community were randomly assigned to wrist weight (WW; n = 12) and no-wrist weight (NW; n = 11) exercise groups while 11 matched subjects served as non-exercise controls (NE). Exercise training was performed for 10 weeks, 3 days/week, for 60 min/session and consisted of low-impact aerobic dance (50-70% of maximal heart rate) combined with exercises to promote muscular fitness, flexibility, and balance. Before and after the intervention, each participant's aerobic fitness, muscular strength, flexibility, static and dynamic balance, skinfold thickness, and psychological mood states were assessed under standardized testing conditions. Exercise training resulted in significant improvements in peak oxygen uptake, lower extremity muscle strength, and psychological vigor (p < 0.05) but did not affect other fitness components (p > 0.05). There were no differences between the WW and NW exercise groups for any of the same variables studied (p > 0.05). No significant pre- to post-test changes were found for the NE control group (p > 0.05). It is concluded that 10 weeks of low-impact, moderate-intensity exercise training of the type that can be considered well-rounded in nature provides a sufficient stimulus to augment aerobic fitness, beneficially affects leg strength, and increases feelings of vigor in older adults. The present observations indicate that the use of light wrist weights has no beneficial or adverse effects on the measured training outcomes. PMID:9657086

    Craniospinal irradiation (CSI) poses a challenging planning process because of the complex target volume. Traditional 3D conformal CSI does not spare any critical organs, resulting in toxicity in patients. Here the dosimetric advantages of intensity-modulated radiation therapy (IMRT) and volumetric-modulated arc therapy (VMAT) are compared with classic conformal planning in adults for both cranial and spine fields to develop a clinically feasible technique that is both effective and efficient. Ten adult patients treated with CSI were retrospectively identified. For the cranial fields, 5-field IMRT and dual 356° VMAT arcs were compared with opposed lateral 3D conformal radiotherapy (3D-CRT) fields. For the spine fields, traditional posterior-anterior (PA) PA fields were compared with isocentric 5-field IMRT plans and single 200° VMAT arcs. Two adult patients have been treated using this IMRT technique to date and extensive quality assurance, especially for the junction regions, was performed. For the cranial fields, the IMRT technique had the highest planned target volume (PTV) maximum and was the least efficient, whereas the VMAT technique provided the greatest parotid sparing with better efficiency. 3D-CRT provided the most efficient delivery but with the highest parotid dose. For the spine fields, VMAT provided the best PTV coverage but had the highest mean dose to all organs at risk (OAR). 3D-CRT had the highest PTV and OAR maximum doses but was the most efficient. IMRT provides the greatest OAR sparing but the longest delivery time. For those patients with unresectable disease that can benefit from a higher, definitive dose, 3D-CRT–opposed laterals are the most clinically feasible technique for cranial fields and for spine fields. Although inefficient, the IMRT technique is the most clinically feasible because of the increased mean OAR dose with the VMAT technique. Quality assurance of the beams, especially the junction regions, is essential.

    Retrospective analysis of third degree perineal lacerations in 7 female camels (6-17 yrs of age) that were surgically corrected by one stage repair (Goetz technique) is presented. Majority (3/7) of the camels was primiparous and all parturitions had a history of calving assistance. Six (6/7) camels recovered by first intention of healing. Dehiscence of perineal structure occurred in only one camel due to infection and healed by second intention. Subsequent matings resulted in pregnancy in four camels and one camel died due to unrelated causes. We conclude that perineal lacerations can occur in primiparous camels with difficult assisted deliveries and that one stage repair of perineal lacerations in camels improves the perineal conformation and such camels may easily regain normal fertility.

    Abstract Background: Surgical site infections (SSI) occur in 1.8%–9.2% of women undergoing cesarean section (CS) and lead to greater morbidity rates and increased treatment costs. The aim of the study was to evaluate the efficacy and cost-effectiveness of dialkylcarbamoyl chloride (DACC) impregnated dressings to prevent SSI in women subject to CS. Methods: Randomized, controlled trial was conducted at the Mazovian Bródno Hospital, a tertiary care center performing approximately 1300 deliveries per year, between June 2014 and April 2015. Patients were randomly allocated to receive either DACC impregnated dressing or standard surgical dressing (SSD) following skin closure. In order to analyze cost-effectiveness of the selected dressings in the group of patients who developed SSI, the costs of ambulatory visits, additional hospitalization, nursing care, and systemic antibiotic therapy were assessed. Independent risk factors for SSI were determined by multivariable logistic regression. Results: Five hundred and forty-three women undergoing elective or emergency CS were enrolled. The SSI rates in the DACC and SSD groups were 1.8% and 5.2%, respectively (p = 0.04). The total cost of SSI prophylaxis and treatment was greater in the control group as compared with the study group (5775 EUR vs. 1065 EUR, respectively). Independent risk factors for SSI included higher pre-pregnancy body mass index (adjusted odds ratio [aOR] = 1.08; [95% confidence interval [CI]: 1.0–1.2]; p < 0.05), smoking in pregnancy (aOR = 5.34; [95% CI: 1.6–15.4]; p < 0.01), and SSD application (aOR = 2.94; [95% CI: 1.1–9.3]; p < 0.05). Conclusion: The study confirmed the efficacy and cost-effectiveness of DACC impregnated dressings in SSI prevention among women undergoing CS. PMID:26891115

    This study aimed to determine the effects of a single high-intensity interval training (HIIT) session on salivary cortisol (SC) levels, physiological responses, and performance in trained boys and men. Twenty-three boys (11.5 ± 0.8 years) and 25 men (29.7 ± 4.6 years) performed HIIT (4 consecutive Wingate Anaerobic Tests). SC in boys and men increased after HIIT from 5.55 ± 3.3 nmol/l to 15.13 ± 9.7 nmol/l (+173%) and from 7.07 ± 4.7 nmol/l to 19.19 ± 12.7 nmol/l (+171%), respectively (p < .01). Pretest SC as well as posttest changes were comparable in both groups (both p < .01). Peak blood lactate concentration was significantly lower in boys (12.6 ± 3.5 mmol/l) than in men (16.3 ± 3.1 mmol/l; p < .01). Throughout the HIIT, mean heart rates in boys were higher (p < .001) but relative peak oxygen uptake (ml·min-1·kg-1; p < .05) and performance were lower (p < .001) in boys than in men. HIIT in young athletes is associated with a higher activation of the hormonal stress axis than other types of exercise regimes as described in the literature. This study is the first to show a pronounced SC increase to HIIT in trained boys accompanied by elevated levels of blood lactate concentrations and heart rate suggesting a high cardio-respiratory, metabolic, and hormonal response to HIIT in 11-year-old boys.

    2013-01-01

    Introduction Although intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are associated with substantial morbidity and mortality among critically ill adults, it remains unknown if prevention or treatment of these conditions improves patient outcomes. We sought to identify evidence-based risk factors for IAH and ACS in order to guide identification of the source population for future IAH/ACS treatment trials and to stratify patients into risk groups based on prognosis. Methods We searched electronic bibliographic databases (MEDLINE, EMBASE, PubMed, and the Cochrane Database from 1950 until January 21, 2013) and reference lists of included articles for observational studies reporting risk factors for IAH or ACS among adult ICU patients. Identified risk factors were summarized using formal narrative synthesis techniques alongside a random effects meta-analysis. Results Among 1,224 citations identified, 14 studies enrolling 2,500 patients were included. The 38 identified risk factors for IAH and 24 for ACS could be clustered into three themes and eight subthemes. Large volume crystalloid resuscitation, the respiratory status of the patient, and shock/hypotension were common risk factors for IAH and ACS that transcended across presenting patient populations. Risk factors with pooled evidence supporting an increased risk for IAH among mixed ICU patients included obesity (four studies; odds ratio (OR) 5.10; 95% confidence interval (CI), 1.92 to 13.58), sepsis (two studies; OR 2.38; 95% CI, 1.34 to 4.23), abdominal surgery (four studies; OR 1.93; 95% CI, 1.30 to 2.85), ileus (two studies; OR 2.05; 95% CI, 1.40 to 2.98), and large volume fluid resuscitation (two studies; OR 2.17; 95% CI, 1.30 to 3.63). Among trauma and surgical patients, large volume crystalloid resuscitation and markers of shock/hypotension and metabolic derangement/organ failure were risk factors for IAH and ACS while increased disease severity scores and elevated creatinine were

    Objectives To assess the safety and acceptance of the PrePex device for medical male circumcision (MMC) in rural Uganda. Methods In an observational study, HIV-uninfected, uncircumcised men aged 18 and older who requested elective MMC were informed about the PrePex and dorsal slit methods and offered a free choice of their preferred procedure. 100 men received PrePex to assess preliminary safety (aim 1). An additional 329 men, 250 chose PrePex and 79 chose Dorsal slit, were enrolled following approval by the Safety Monitoring Committee (aim 2). Men were followed up at 7 days to assess adverse events (AEs) and to remove the PrePex device. Wound healing was assessed at 4 weeks, with subsequent weekly follow up until completed healing. Results The PrePex device was contraindicated in 5.7% of men due to a tight prepuce or phimosis/adhesions. Among 429 enrolled men 350 (82.0%) got the PrePex device and 79 (18.0%) the dorsal slit procedure. 250 of 329 men (76.0%) who were invited to choose between the 2 procedures chose Prepex. There were 9 AEs (2.6%) with the PrePex, of which 5 (1.4%) were severe complications, 4 due to patient self-removal of the device leading to edema and urinary obstruction requiring emergency surgical circumcision, and one due to wound dehiscence following device removal. 71.8% of men reported an unpleasant odor prior to PrePex removal. Cumulative rates of completed wound healing with the PrePex were 56.7% at week 4, 84.8% week 5, 97.6% week 6 and 98.6% week 7, compared to 98.7% at week 4 with dorsal slit (p<0.0001). Conclusion The PrePex device was well accepted, but healing was slower than with dorsal slit surgery. Severe complications, primarily following PrePex self-removal, required rapid access to emergency surgical facilities. The need to return for removal and delayed healing may increase Program cost and client burden. PMID:25144194

    Background We present our experience in the treatment of patients with isthmic or degenerative spondylolisthesis, by means of a posterior lumbar interbody fusion (PLIF) and instrumented posterolateral fusion (IPLF), and we compare them with those published in the literature. We analyse whether there exists any statistical association between the clinical characteristics of the patient, radiological characteristics of the disease and our surgical technique, with the complications and the clinical-radiological prognosis of the cases. Method We designed a prospective study. A total of 36 cases were operated. The patients included were 14 men and 22 women, with an average age of 57.17±27.32 years. Our technique consists of PLIF+IPLF, using local bone for the fusion. The clinical results were evaluated with the Visual Analogical Scale (VAS) and the Kirkaldy-Willis criteria. The radiological evaluation followed the Bratingan (PLIF) and Lenke (IPLF) methodology. A total of 42 variables were statistically analysed by means of SPSS18. We used the Paired Student's T-test, logistic regression and Pearson's Chi-square-test. Results The spondylolisthesis was isthmic in 15 cases and degenerative in 21 cases. The postoperative evaluations had excellent or good results in 94.5% (n = 34), with a statistically significant improvement in the back pain and sciatica (p < 0.01). The rate of circumferential fusion reached was approximately 92%. We had 13.88% of transitory morbility and 0% of mortality associated with our technique. A greater age, degree of listhesis or length of illness before the intervention, weakly correlated with worse clinical results (p< -0.2). In our series, the logistical regression showed that the clinical characteristics of the patient, radiological characteristics of the lesion and our surgical technique were not associated with greater postoperative complications. Conclusion Although a higher level of training is necessary, we believe that the described

    This review article, the second in a series of articles to examine the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) Guidelines for the Use of Parenteral and Enteral Nutrition in Adult and Pediatric Patients, evaluates the evidence related to the use of nutrition support in surgical oncology patients. Cancer patients develop complex nutrition issues. Nutrition support may be indicated in malnourished cancer patients undergoing surgery, depending on individual patient characteristics. As with the first article in this series, this article provides background concerning nutrition issues in cancer patients, as well as discusses the role of nutrition support in the care of surgical cancer patients. The goal of this review is to enrich the discussion contained in the clinical guidelines as they relate to recommendations made for surgical patients, cite the primary literature more completely, and suggest updates to the guideline statements in light of subsequently published studies.

  1. Cost utility analysis of reduced intensity hematopoietic stem cell transplantation in adolescence and young adult with severe thalassemia compared to hypertransfusion and iron chelation program

    PubMed Central

    2013-01-01

    Background Hematopoieticic stem cell transplantation is the only therapeutic option that can cure thalassemia disease. Reduced intensity hematopoietic stem cell transplantation (RI-HSCT) has demonstrated a high cure rate with minimal complications compared to other options. Because RI-HSCT is very costly, economic justification for its value is needed. This study aimed to estimate the cost-utility of RI-HSCT compared with blood transfusions combined with iron chelating therapy (BT-ICT) for adolescent and young adult with severe thalassemia in Thailand. Methods A Markov model was used to estimate the relevant costs and health outcomes over the patients’ lifetimes using a societal perspective. All future costs and outcomes were discounted at a rate of 3% per annum. The efficacy of RI-HSCT was based a clinical trial including a total of 18 thalassemia patients. Utility values were derived directly from all patients using EQ-5D and SF-6D. Primary outcomes of interest were lifetime costs, quality adjusted life-years (QALYs) gained, and the incremental cost-effectiveness ratio (ICER) in US ($) per QALY gained. One-way and probabilistic sensitivity analyses (PSA) were conducted to investigate the effect of parameter uncertainty. Results In base case analysis, the RI-HSCT group had a better clinical outcomes and higher lifetime costs. The incremental cost per QALY gained was US $ 3,236 per QALY. The acceptability curve showed that the probability of RI-HSCT being cost-effective was 71% at the willingness to pay of 1 time of Thai Gross domestic product per capita (GDP per capita), approximately US $ 4,210 per QALY gained. The most sensitive parameter was utility of severe thalassemia patients without cardiac complication patients. Conclusion At a societal willingness to pay of 1 GDP per capita, RI-HSCT was a cost-effective treatment for adolescent and young adult with severe thalassemia in Thailand compared to BT-ICT.

    Myeloablative conditioning regimens for hematopoietic stem cell transplant (HSCT) are known to affect endocrine function, but little is known regarding reduced intensity conditioning (RIC) regimens. We retrospectively reviewed 114 children and young adults after single RIC HSCT. The analysis was grouped by age (<2 and ⩾2 years) and diagnosis (hemophagocytic lymphohistiocystosis/X-linked lymphoproliferative syndrome (HLH/XLP), other immune disorders, metabolic/genetic disorders). All groups displayed short stature by mean height-adjusted Z-score (HAZ) before (-1.29) and after HSCT (HAZ -1.38, P=0.47). After HSCT, younger children with HLH/XLP grew better (HAZ -3.41 vs -1.65, P=0.006), whereas older subjects had decline in growth (HAZ -0.8 vs -1.01, P=0.06). Those with steroid therapy beyond standard GVHD prophylaxis were shorter than those without (P 0.04). After HSCT, older subjects with HLH/XLP became thinner with a mean body mass index (BMI) Z-score of 1.20 vs 0.64, P=0.02, and similar to metabolic/genetic disorders (BMI-Z= 0.59 vs -0.99, P<0.001). BMI increased among younger children in these same groups. Thyroid function was abnormal in 24% (18/76). 25-OH vitamin D levels were insufficient in 73% (49/65), with low bone mineral density in 8 of 19 evaluable subjects. Despite RIC, children and young adults still have significant late endocrine effects. Further research is required to compare post-transplant endocrine effects after RIC to those after standard chemotherapy protocols. PMID:26974276

    This article reports a study of the physical design characteristics of a set of adult intensive care units (ICUs), built between 1993 and 2003. These ICUs were recognized as the best-practice examples by the Society of Critical Care Medicine, the American Association of Critical Care Nurses, and the American Institute of Architects. This study is based on a systematic analysis of the materials found on these ICUs in the booklet and videos jointly published by the above organizations in 2005. The study finds that most of these examples of best-practice adult ICUs have the following negative characteristics: (1) they are built as renovation projects with more health and safety hazards during construction; (2) most of them are mixed-service units with more safety and staffing problems; (3) the overall layout and the layout of staff work areas in these ICUs do not have any common design solutions for improved patient and staff outcomes; and (4) in these ICUs, family space is often located outside the unit, and family access to the patient room is restricted, even though family presence at the bedside may be important for improved patient outcomes. Some of these negative characteristics are offset by the following positive characteristics in most ICUs: (1) they have only private patient rooms for improved patient care, safety, privacy, and comfort; (2) most patient beds are freestanding for easy access to patients from all sides; (3) they have handwashing sinks and waste disposal facilities in the patient room for improved safety; and (4) most patient rooms have natural light to help patients with circadian rhythms. The article discusses, in detail, the implications of its findings, and the role of the ICU design community in a very complicated design context. PMID:17063097

    Housing First (HF) is being widely disseminated in efforts to end homelessness among homeless adults with psychiatric disabilities. This study evaluates the effectiveness of HF with Intensive Case Management (ICM) among ethnically diverse homeless adults in an urban setting. 378 participants were randomized to HF with ICM or treatment-as-usual (TAU) in Toronto (Canada), and followed for 24 months. Measures of effectiveness included housing stability, physical (EQ5D-VAS) and mental (CSI, GAIN-SS) health, social functioning (MCAS), quality of life (QoLI20), and health service use. Two-thirds of the sample (63%) was from racialized groups and half (50%) were born outside Canada. Over the 24 months of follow-up, HF participants spent a significantly greater percentage of time in stable residences compared to TAU participants (75.1% 95% CI 70.5 to 79.7 vs. 39.3% 95% CI 34.3 to 44.2, respectively). Similarly, community functioning (MCAS) improved significantly from baseline in HF compared to TAU participants (change in mean difference = +1.67 95% CI 0.04 to 3.30). There was a significant reduction in the number of days spent experiencing alcohol problems among the HF compared to TAU participants at 24 months (ratio of rate ratios = 0.47 95% CI 0.22 to 0.99) relative to baseline, a reduction of 53%. Although the number of emergency department visits and days in hospital over 24 months did not differ significantly between HF and TAU participants, fewer HF participants compared to TAU participants had 1 or more hospitalizations during this period (70.4% vs. 81.1%, respectively; P=0.044). Compared to non-racialized HF participants, racialized HF participants saw an increase in the amount of money spent on alcohol (change in mean difference = $112.90 95% CI 5.84 to 219.96) and a reduction in physical community integration (ratio of rate ratios = 0.67 95% CI 0.47 to 0.96) from baseline to 24 months. Secondary analyses found a significant reduction in the number of days

    Objective To systematically review and describe currently available approaches to supporting maintenance of weight loss in obese adults and to assess the evidence for the effectiveness of these interventions. Design Systematic review with meta-analysis. Data sources Medline, PsycINFO, Embase, and the Cochrane Central Register of Controlled Trials. Study selection Studies were identified through to January 2014. Randomised trials of interventions to maintain weight loss provided to initially obese adults (aged ≥18) after weight loss of ≥5% body weight with long term (≥12 months) follow-up of weight change (main outcome) were included. Study appraisal and synthesis Potential studies were screened independently and in duplicate; study characteristics and outcomes were extracted. Meta-analyses were conducted to estimate the effects of interventions on weight loss maintenance with the inverse variance method and a random effects model. Results are presented as mean differences in weight change, with 95% confidence intervals. Results 45 trials involving 7788 individuals were included. Behavioural interventions focusing on both food intake and physical activity resulted in an average difference of −1.56 kg (95% confidence interval −2.27 to −0.86 kg; 25 comparisons, 2949 participants) in weight regain compared with controls at 12 months. Orlistat combined with behavioural interventions resulted in a −1.80 kg (−2.54 to −1.06; eight comparisons, 1738 participants) difference compared with placebo at 12 months. All orlistat studies reported higher frequencies of adverse gastrointestinal events in the experimental compared with placebo control groups. A dose-response relation for orlistat treatment was found, with 120 mg doses three times a day leading to greater weight loss maintenance (−2.34 kg, −3.03 to −1.65) compared with 60 mg and 30 mg three times a day (−0.70 kg, 95% confidence interval −1.92 to 0.52), P=0.02.

    Sixteen patients with adult T-cell leukemia/lymphoma (ATL) who were all over 50 years of age underwent allogeneic stem cell transplantation with reduced-conditioning intensity (RIST) from HLA-matched sibling donors after a conditioning regimen consisting of fludarabine (180 mg/m2), busulfan (8 mg/kg), and rabbit antithymocyte globulin (5 mg/kg). The observed regimen-related toxicities and nonhematologic toxicities were all found to be acceptable. Disease relapse was the main cause of treatment failure. Three patients who had a relapse subsequently responded to a rapid discontinuation of the immunosuppressive agent and thereafter achieved another remission. After RIST, the human T-cell leukemia virus type 1 (HTLV-1) proviral load became undetectable in 8 patients. RIST is thus considered to be a feasible treatment for ATL. Our data also suggest the presence of a possible graft-versus-ATL effect; an anti-HTLV-1 activity was also found to be associated with this procedure. PMID:15665110

    The role of physical activity as a factor that protects against stress-related mental disorders is well documented. Nevertheless, there is still a dearth of research using objective measures of physical activity. The present study examines whether objectively assessed vigorous physical activity (VPA) is associated with mental health benefits beyond moderate physical activity (MPA). Particularly, this study examines whether young adults who accomplish the American College of Sports Medicine's (ACSM) vigorous-intensity exercise recommendations differ from peers below these standards with regard to their level of perceived stress, depressive symptoms, perceived pain, and subjective and objective sleep. A total of 42 undergraduate students (22 women, 20 men; M=21.24years, SD=2.20) volunteered to take part in the study. Stress, pain, depressive symptoms, and subjective sleep were assessed via questionnaire, objective sleep via sleep-EEG assessment, and VPA via actigraphy. Meeting VPA recommendations had mental health benefits beyond MPA. VPA was associated with less stress, pain, subjective sleep complaints and depressive symptoms. Moreover, vigorous exercisers had more favorable objective sleep pattern. Especially, they had increased total sleep time, more stage 4 and REM sleep, more slow wave sleep and a lower percentage of light sleep. Vigorous exercisers also reported fewer mental health problems if exposed to high stress. This study provides evidence that meeting the VPA standards of the ACSM is associated with improved mental health and more successful coping among young people, even compared to those who are meeting or exceeding the requirements for MPA.

    The pedagogical approach to surgical training has changed significantly over the past few decades. No longer are surgical skills solely acquired through a traditional apprenticeship model of training. The acquisition of many technical and nontechnical skills is moving from the operating room to the surgical skills laboratory through the use of simulation. Many platforms exist for the learning and assessment of surgical skills. In this article, the authors provide a broad overview of some of the currently available surgical simulation modalities including bench-top models, laparoscopic simulators, simulation for new surgical technologies, and simulation for nontechnical surgical skills.

    OBJECTIVE The objective of this study was to assess the cross-sectional areas (CSAs) of lumbar paraspinal muscles in adults with isthmic spondylolisthesis (IS), to compare them with those in the normative population, and to evaluate their correlations with demographic factors and MRI changes in various spinal elements. METHODS The authors conducted a retrospective study of patients who had undergone posterior lumbar interbody fusion for IS, and 2 of the authors acting as independent observers calculated the CSAs of various lumbar paraspinal muscles (psoas, erector spinae [ES], multifidus [MF]) on preoperative axial T2-weighted MR images from the L-3 to L-5 vertebral levels and computed the CSAs as ratios with respect to the corresponding vertebral body areas. These values were then compared with those in an age- and sex-matched normative population and were analyzed with respect to age, sex, duration of symptoms, grade of listhesis, and various MRI changes at the level of the listhesis (pedicle signal change, disc degeneration, and facetal arthropathy). RESULTS Compared with values in normative controls, the mean CSA value for the ES muscle was significantly higher in the study cohort of 120 patients (p = 0.002), whereas that for the MF muscle was significantly lower (p = 0.009), and more so in the patients with PSC (p = 0.002). Magnetic resonance imaging signal change in the pedicle was seen in half of the patients, all of whom demonstrated a Type 2 change. Of the variables tested in a multivariate analysis, age independently predicted lower area values for all 3 muscles (p ≤ 0.001), whereas female sex predicted a lower mean psoas area value (p < 0.001). None of the other variables significantly predicted any of the muscle area values. A decrease in the mean MF muscle area value alone was associated with a significantly increased likelihood of a PSC (p = 0.039). CONCLUSIONS Compared with normative controls, patients with IS suffer selective atrophy of their MF

  10. Statistical process control of mortality series in the Australian and New Zealand Intensive Care Society (ANZICS) adult patient database: implications of the data generating process

    2013-01-01

    Background Statistical process control (SPC), an industrial sphere initiative, has recently been applied in health care and public health surveillance. SPC methods assume independent observations and process autocorrelation has been associated with increase in false alarm frequency. Methods Monthly mean raw mortality (at hospital discharge) time series, 1995–2009, at the individual Intensive Care unit (ICU) level, were generated from the Australia and New Zealand Intensive Care Society adult patient database. Evidence for series (i) autocorrelation and seasonality was demonstrated using (partial)-autocorrelation ((P)ACF) function displays and classical series decomposition and (ii) “in-control” status was sought using risk-adjusted (RA) exponentially weighted moving average (EWMA) control limits (3 sigma). Risk adjustment was achieved using a random coefficient (intercept as ICU site and slope as APACHE III score) logistic regression model, generating an expected mortality series. Application of time-series to an exemplar complete ICU series (1995-(end)2009) was via Box-Jenkins methodology: autoregressive moving average (ARMA) and (G)ARCH ((Generalised) Autoregressive Conditional Heteroscedasticity) models, the latter addressing volatility of the series variance. Results The overall data set, 1995-2009, consisted of 491324 records from 137 ICU sites; average raw mortality was 14.07%; average(SD) raw and expected mortalities ranged from 0.012(0.113) and 0.013(0.045) to 0.296(0.457) and 0.278(0.247) respectively. For the raw mortality series: 71 sites had continuous data for assessment up to or beyond lag40 and 35% had autocorrelation through to lag40; and of 36 sites with continuous data for ≥ 72 months, all demonstrated marked seasonality. Similar numbers and percentages were seen with the expected series. Out-of-control signalling was evident for the raw mortality series with respect to RA-EWMA control limits; a seasonal ARMA model, with GARCH effects

    2016-01-01

    Surgical fusion of the subtalar joint is a procedure indicated to alleviate pain of subtalar origin, such as in post-traumatic osteoarthritis, adult-acquired flatfoot deformity, and other disorders. Open subtalar arthrodesis has been performed with predictable results, but concerns exist regarding injury to proprioception and local vascularity due to wide surgical dissection. Minimally invasive techniques try to improve results by avoiding these issues but have a reputation for being technically demanding. We describe the surgical technique for arthroscopic subtalar arthrodesis, which has proved to be a safe and reliable technique in our experience, with consistent improvements in American Orthopaedic Foot & Ankle Society scores.

    IMPORTANCE Knee osteoarthritis (OA), a common cause of chronic pain and disability, has biomechanical and inflammatory origins and is exacerbated by obesity. OBJECTIVE To determine whether a ≥10% reduction in body weight induced by diet, with or without exercise, would improve mechanistic and clinical outcomes more than exercise alone. DESIGN, SETTING, AND PARTICIPANTS Single-blind, 18-month, randomized clinical trial at Wake Forest University between July 2006 and April 2011. The diet and exercise interventions were center-based with options for the exercise groups to transition to a home-based program. Participants were 454 overweight and obese older community-dwelling adults (age ≥55 years with body mass index of 27–41) with pain and radiographic knee OA. INTERVENTIONS Intensive diet-induced weight loss plus exercise, intensive diet-induced weight loss, or exercise. MAIN OUTCOMES AND MEASURES Mechanistic primary outcomes: knee joint compressive force and plasma IL-6 levels; secondary clinical outcomes: self-reported pain (range, 0–20), function (range, 0–68), mobility, and health-related quality of life (range, 0–100). RESULTS At 18 months, 399 participants (88%) completed the study. Compared with exercise participants, knee compressive forces were lower in diet participants and IL-6 levels were lower in diet and diet + exercise participants. 18-mo Outcomes, Mean (95% CI) Exercise(E) Diet (D) D + E Difference,E vs D Difference, Evs D+E Weight loss, kg −1.8(−5.7to1.8) −8.9(−12.4 to −5.3) −10.6(−14.1 to −7.1) Knee compressiveforces, N 2687(2590 to 2784) 2487(2393 to 2581) 2543(2448 to 2637) 200(55 to 345)a 144(1 to 287) IL-6, pg/mL 3.1(2.9 to 3.4) 2.7(2.4 to 3.0) 2.7(2.5 to 3.0) 0.43(0.01 to 0.85)a 0.39(−0.03 to 0.81)a Pain 4.7(4.2 to 5.1) 4.8(4.3 to 5.2) 3.6(3.2 to 4.1) −0.11(−0.81 to 0.59) 1.02(0.33 to 1.71)a Function 18.4(16.9 to 19.9) 17.4(15.9 to 18.9) 14.1(12.6 to 15.6) 0.98(−1.24 to 3.20) 4.29(2.07 to 6.50)a SF-36

    Unfortunately, the overpopulation of dogs is still a problem in the majority of countries and even though surgical methods of sterilization, the most traditional and commonly used technique, have been intensively performed, the impact on the dog population is negligible. The neutering of companion animals as ovariohysterectomy (spaying) or orchidectomy (castration) has its limitations because of the cost, the need of a surgical environment and the risk of surgical and/or anaesthetical complications (ACCD 2009). In fact, surgical castration has been banished in some northern European countries and has limited acceptance in other countries. In a survey performed in Sao Paulo, Brazil, 56.5% of the owners of adopted shelter dogs were against the surgical procedure for different reasons (Soto et al. 2005). Currently, the options for contraception, defined as suppression of fertility are based on hormonal treatment. The treatments can be divided into analogues of gonadotropin releasing hormone (GnRH), progestins and androgens. Other possibilities of contraception are via the immunological system with vaccinations against GnRH, the luteinizing hormone (LH) receptor and the zona pellucida proteins. Finally, there is also the intra-epididymal or intratesticular injection of sclerosing substances in dogs. Mechanical devices to disrupt fertility are not used anymore due to the side effects. Suppression of fertility in adult dogs will be reviewed in order of use and possible impact on the dog population. PMID:24947862

    Treatment options for urological malignancies continue to increase and include endoscopic, laparoscopic, robotic, and image-guided percutaneous techniques. This ever expanding array of technically demanding management options coupled with a static training paradigm introduces challenges to training the urological oncologist of the future. Minimally invasive learning opportunities continue to evolve, and include an intensive experience during residency, postgraduate short courses or mini-apprenticeships, and full time fellowship programs. Incorporation of large animal surgery and surgical simulators may help shorten the necessary learning curve. Ultimately, programs must provide an intense hands-on experience to trainees in all minimally invasive surgical aspects for optimal training. PMID:19285236

    Background: Blue light has more energy than longer wavelength light and can penetrate the eye to reach the retina. When surgeons use magnifying loupes under intensive surgical shadowless lamps for better view of the surgical field, the total luminance is about 200 times brighter than that of typical office lighting. In this study, the effects of 2 types of shadowless lamps were compared. Moreover, the effect of various eyeglasses, which support magnifying loupes, on both the light energy and color rendering was considered. Methods: The light intensity and color rendering were measured on 3 variables: light transmittance, light intensity, and color rendering. Results: Under shadowless lamps, the light energy increased with low-magnification loupes and decreased with high-magnification loupes. Filtering eyeglasses reduced the energy, especially in conditions where the low-magnification loupe was used. The best color-rendering index values were obtained with computer eyeglasses under conventional light-emitting diode shadowless lamps and with no glass and with lightly yellow-tinted lenses under less-blue light-emitting diode. Conclusions: Microsurgeons are exposed to strong lighting throughout their career, and proper color rendering must be considered for easier recognition. Light toxicity and loss of color rendering can be reduced with an appropriate combination of shadowless lamps and colored eyeglasses. PMID:26893987

    Objective: To describe functional outcomes following surgical treatment of patients with patellofemoral instability submitted to patellar realignment. Methods: This was a retrospective study evaluating 34 operated knees for patellofemoral instability between 1989 and 2004. The patients were evaluated in the late postoperative period when a functional questionnaire was applied. Results: After a mean follow-up time of 6 years and 5 months, the mean score was 82.94 in the surgical group (p=0.00037). The results of this investigation showed pain relief in 97.05% and low rate of recurrent dislocation (5.88%), although lower scores were seen in intense articular activities (squatting, running and jumping). No patient developed osteoarthritis while being followed up. Conclusion: The procedure for joint described in this paper was shown to be effective for treating patients with recurrent patellofemoral instability. PMID:27077065

    Background Several circumcision devices have been evaluated for a safe and simplified male circumcision among adults. The PrePex device was prequalified for voluntary male medical circumcision (VMMC) in May 2013 by the World Health Organization and is expected to simplify the procedure safely while reducing cost. South Africa is scaling up VMMC. Objective To evaluate the overall unit cost of VMMC at a mixed site vs. a hypothetical PrePex-only site in South Africa. Design We evaluated the overall unit cost of VMMC at a mixed site where PrePex VMMC procedure was added to routine forceps-guided scalpel-based VMMC in Soweto, South Africa. We abstracted costs and then modeled these costs for a hypothetical PrePex-only site, at which 9,600 PrePex circumcisions per year could be done. We examined cost drivers and modeled costs, varying the price of the PrePex device. The healthcare system perspective was used. Results In both sites, the main contributors of cost were personnel and consumables. If 10% of all VMMC were by PrePex at the mixed site, the overall costs of the surgical method and PrePex were similar – US$59.62 and $59.53, respectively. At the hypothetical PrePex-only site, the unit cost was US$51.10 with PrePex circumcisions having markedly lower personnel and biohazardous waste management costs. In sensitivity analysis with the cost of PrePex kit reduced to US$10 and $2, the cost of VMMC was further reduced. Conclusions Adding PrePex to an existing site did not necessarily reduce the overall costs of VMMC. However, starting a new PrePex-only site is feasible and may significantly reduce the overall cost by lowering both personnel and capital costs, thus being cost-effective in the long term. Achieving a lower cost for PrePex will be an important contributor to the scale-up of VMMC. PMID:26679407

    Surgical treatment of talus fractures can challenge even the most skilled foot and ankle surgeon. Complicated fracture patterns combined with joint dislocation of variable degrees require accurate assessment, sound understanding of principles of fracture care, and broad command of internal fixation techniques needed for successful surgical care. Elimination of unnecessary soft tissue dissection, a low threshold for surgical reduction, liberal use of malleolar osteotomy to expose body fracture, and detailed attention to fracture reduction and joint alignment are critical to the success of treatment. Even with the best surgical care complications are common and seem to correlate with injury severity and open injuries. PMID:19121756

    2016-01-01

    BACKGROUND Acute kidney injury (AKI) is an important complication in surgical patients. Existing biomarkers and clinical prediction models underestimate the risk for developing AKI. We recently reported data from two trials of 728 and 408 critically ill adult patients in whom urinary TIMP2•IGFBP7 (NephroCheck, Astute Medical) was used to identify patients at risk of developing AKI. Here we report a preplanned analysis of surgical patients from both trials to assess whether urinary tissue inhibitor of metalloproteinase 2 (TIMP-2) and insulin-like growth factor–binding protein 7 (IGFBP7) accurately identify surgical patients at risk of developing AKI. STUDY DESIGN We enrolled adult surgical patients at risk for AKI who were admitted to one of 39 intensive care units across Europe and North America. The primary end point was moderate-severe AKI (equivalent to KDIGO [Kidney Disease Improving Global Outcomes] stages 2–3) within 12 hours of enrollment. Biomarker performance was assessed using the area under the receiver operating characteristic curve, integrated discrimination improvement, and category-free net reclassification improvement. RESULTS A total of 375 patients were included in the final analysis of whom 35 (9%) developed moderate-severe AKI within 12 hours. The area under the receiver operating characteristic curve for [TIMP-2]•[IGFBP7] alone was 0.84 (95% confidence interval, 0.76–0.90; p < 0.0001). Biomarker performance was robust in sensitivity analysis across predefined subgroups (urgency and type of surgery). CONCLUSION For postoperative surgical intensive care unit patients, a single urinary TIMP2•IGFBP7 test accurately identified patients at risk for developing AKI within the ensuing 12 hours and its inclusion in clinical risk prediction models significantly enhances their performance. LEVEL OF EVIDENCE Prognostic study, level I. PMID:26816218

    Three in-vivo observations stimulated interest in surgical treatment for emphysema: (a) the destructive changes are rarely generalized, (b) the central portions of the lungs are frequently less seriously affected, and (c) marginal folding produces obstructive change in the more normal lung tissue. If destroyed avascular space-occupying areas can be removed, the compressed lung tissue may be stretched to fill pleural space in a functionally effective fashion. Residual elastic tissue will them maintain patency of terminal bronchioles. Preoperatively the extent of the destructive change can be defined most accurately by pulmonary angiography, and zones of functioning capilary circulation can be identified. Forty-seven patients with multifocal space-occupying emphysematous change have been treated surgically. The postoperative mortality was 21% but worthwhile long-term improvement has been obtained in 45% of patients presenting with disabling dyspnea. In these patients, surgical treatment warrants consideration if significant space occupation accompanies the bullous disease, provided alveolar vascularization can be demonstrated in the compressed adjacent normal lung tissue. Limited resections that preserve all vascularized and potentially functioning lung tissue are preferable. It is essential that obliteration of the hemithorax be obtained promptly in view of the high incidence of postoperative complications requiring secondary operative procedures, if 'leaks' and residual spaces are allowed to persist. Postoperative care in a respiratory intensive care unit is mandatory. PMID:870155

    The effects of physical activity on cognition in older adults have been extensively investigated in the last decade. Different interventions such as aerobic, strength, and gross motor training programs have resulted in improvements in cognitive functions. However, the mechanisms underlying the relationship between physical activity and cognition are still poorly understood. Recently, it was shown that acute bouts of exercise resulted in reduced executive control at higher relative exercise intensities. Considering that aging is characterized by a reduction in potential energy ([Formula: see text] max - energy cost of walking), which leads to higher relative walking intensity for the same absolute speed, it could be argued that any intervention aimed at reducing the relative intensity of the locomotive task would improve executive control while walking. The objective of the present study was to determine the effects of a short-term (8 weeks) high-intensity strength and aerobic training program on executive functions (single and dual task) in a cohort of healthy older adults. Fifty-one participants were included and 47 (age, 70.7 ± 5.6) completed the study which compared the effects of three interventions: lower body strength + aerobic training (LBS-A), upper body strength + aerobic training (UBS-A), and gross motor activities (GMA). Training sessions were held 3 times every week. Both physical fitness (aerobic, neuromuscular, and body composition) and cognitive functions (RNG) during a dual task were assessed before and after the intervention. Even though the LBS-A and UBS-A interventions increased potential energy to a higher level (Effect size: LBS-A-moderate, UBS-A-small, GMA-trivial), all groups showed equivalent improvement in cognitive function, with inhibition being more sensitive to the intervention. These findings suggest that different exercise programs targeting physical fitness and/or gross motor skills may lead to equivalent improvement in

    The generation, storage, transfer, and representation of image data in radiology are standardized by DICOM. To cover the needs of image guided surgery or computer assisted surgery in general one needs to handle patient information besides image data. A large number of objects must be defined in DICOM to address the needs of surgery. We propose an analysis process based on Surgical Workflows that helps to identify these objects together with use cases and requirements motivating for their specification. As the first result we confirmed the need for the specification of representation and transfer of geometric models. The analysis of Surgical Workflows has shown that geometric models are widely used to represent planned procedure steps, surgical tools, anatomical structures, or prosthesis in the context of surgical planning, image guided surgery, augmented reality, and simulation. By now, the models are stored and transferred in several file formats bare of contextual information. The standardization of data types including contextual information and specifications for handling of geometric models allows a broader usage of such models. This paper explains the specification process leading to Geometry Mesh Service Object Pair classes. This process can be a template for the definition of further DICOM classes.

    Despite modern intensive care management, acute mediastinitis is still associated with a high morbidity and mortality (up to approximately 40 %). Effective antibiotic therapy, intensive care management, elimination of the causative sources of infection and drainage of the affected mediastinal compartments are the cornerstones of therapy in a multidisciplinary treatment concept. Early diagnosis, prompt and uncompromising initial therapy and planned computed tomography (CT) control after the first stages of therapy in order to decide on the necessity for surgical re-interventions are essential for achieving optimal results. Knowledge of the specific anatomical characteristics is crucial for the understanding of this disease and its treatment; therefore, the current knowledge on fascial layers and interstitial spaces from the neck to the mediastinum is described and discussed. A possible foudroyant spread of the infection, especially within the posterior mediastinum, has to be anticipated. The approach to the mediastinum depends on the mediastinal compartments affected, on the causative disease and on the patient's clinical situation. The surgical approach should be adapted to the particular clinical situation of the individual patient and to the surgical experience of the surgeon. When in doubt, the more invasive approach to the mediastinum, such as bilateral thoracotomy, is recommended. An ascending mediastinitis due to pancreatitis is a very rare condition; however, as chest pains are often the main clinical sign surgeons should be aware of this differential diagnosis. An intraoperative brown-black serous fluid in the mediastinal tissue is virtually pathognomonic. The treatment results of esophageal perforation as the most frequent cause of mediastinitis have been improved by integration of various interventional procedures. Hyperbaric oxygen therapy or immunoglobulin treatment can play an auxiliary role in selected patients with acute mediastinitis. PMID

    The four arm study investigates how use of a preoperative forced-air warming blanket and adjustment of ambient surgical room temperature may contribute to prevention of perioperative hypothermia. Active warming interventions may prevent the drop in core temperature that occur as a result of surgical anesthesia. Core body temperatures from a convenience sample of 220 adult surgical patients were sequentially monitored in the preoperative, intraoperative, and post-anesthesia care units (PACU) while receiving: (a) routine surgical care, (b) application of preoperative forced-air warming blanket, (c) application of preoperative forced-air warming blanket with adjustment of ambient surgical room temperatures, or (d) adjustment of ambient surgical room temperature only. Sample characteristics were evenly distributed among the four groups. There were no statistical differences in PACU core body temperatures. The application of forced-air warming blankets and room temperature adjustment interventions were not more effective than current practice in preventing perioperative hypothermia. PMID:24913925

    Over eight years, 58 rural Nigerians with pericarditis were treated surgically in Zaria using basic surgical facilities. Eighteen patients had purulent pericarditis, associated with staphylococcal pneumonia in children, or pneumococcal pneumonia in adults. Treatment with antibiotics and prompt pericardiectomy appeared to be superior to drainage, since a quarter of those initially treated with surgical drainage developed early constriction and required pericardiectomy soon after. Thirteen patients had chronic pericardial effusions, of whom one had epicardial constriction and two had cardiomyopathy. Twenty-seven patients had chronic constrictive pericarditis but tuberculosis was confirmed histologically in three only. Echocardiographic findings remained unchanged in five patients evaluated before and after pericardiectomy. Eight of the 13 patients who died had already developed myocardial or hepatic insufficiency before operation, because of late presentation or diagnosis. Greater awareness of the significance of precordial pain in this rural population where ischaemic heart disease is rare would help in making an earlier diagnosis. Images PMID:7314033

    A project was undertaken to improve robotic surgical tools for telerobotic minimally invasive surgery. The major objectives were to reduce the size of the tools to permit new surgical procedures in confined spaces such as the heart and to improve control of surgical tools by locating positional sensors and actuators at the end effector rather than external to the patient as is currently the state of the technology. A new compact end-effector with wrist-like flexibility was designed. Positional sensors based on MEMS microfabrication techniques were designed.

    Mills, S A

    1982-01-01

    Infective endocarditis of bacterial or fungal origin may arise in either the left or the right heart and can involve both natural and prosthetic valves. The diagnosis is based primarily upon clinical criteria and positive blood cultures, but serial electrocardiograms, fluoroscopy, and two-dimensional echocardiograms may also be helpful. The initial treatment should consist of antibiotic therapy and is itself often adequate in effecting cure. However, careful observation during antibiotic treatment is mandatory, since the development of congestive heart failure due to valvular obstruction or destruction can be an indication for surgical intervention. Other surgical indications include a failure to respond to antibiotic therapy, pulmonary or systemic emboli, evidence of abscess involving the valvular ring (particularly prevalent with prosthetic valve endocarditis), Brucella infection, and the onset of conduction disturbances. The goals of surgical treatment are removal of infective tissue, restoration of valve function, and correction of associated mechanical disorders. The results are surprisingly good, especially for a condition of this severity. Images Fig. 2. Fig. 3. Fig. 4. Fig. 5. Fig. 6. PMID:7065743

    To study the associations of annoyance to noise and exposure to residential traffic with sociodemographic, socioeconomic and regional characteristics as well as housing conditions, a population-based sample of 7,988 adults 18-79 years of age was studied in the German Health Interview and Examination Survey for Adults (DEGS1). Annoyance to noise and exposure to residential traffic were assessed by self-administered questionnaires. A total of 6.3 % of the participants reported a high to very high exposure to residential traffic noise, 3.7 % to neighbourhood noise and 2.1 % to aircraft noise. An excessive exposure to residential traffic was reported by 21.3 % of the participants. A high annoyance to traffic and neighborhood noise was associated with a lower equivalised disposable income and poor housing conditions. Additionally annoyance to neighborhood noise was associated with low socioeconomic and occupational status. A high annoyance to aircraft noise was only associated with a low equivalised disposable income and living in apartment blocks. Exposure to residential traffic was associated with all investigated indicators. At present in Germany environmental exposures are social unequally distributed and may lead to negative health consequences in social disadvantaged groups.

    2003-12-01

    Measuring the frequency of a defined outcome flaw for a series of patients undergoing operative procedures generates information for performance evaluation. Such data influence decisions to improve care if used responsibly. Wound infection (WI), bacterial invasion of the incision, is the most common infectious complication of surgical care and WI prevention has value because the complication affects economic, patient satisfaction, and patient functional status outcomes. WI frequency, one kind of surgical outcome flaw rate, is traditionally used to judge one aspect of surgical care quality. At the author's institution, global WI surveillance was conducted without interruption for 20 years. Results for 85,260 consecutive inpatient operations performed during the period showed that secular changes in infection rates occurred but were not necessarily caused by surgical care quality decrements.

    Traumatic brain injury (TBI) is one of the main causes of mortality and severe disability in young and middle age patients. Patients with severe TBI, who are in coma, are of particular concern. Adequate diagnosis of primary brain injuries and timely prevention and treatment of secondary injury mechanisms markedly affect the possibility of reducing mortality and severe disability. The present guidelines are based on the authors' experience in developing international and national recommendations for the diagnosis and treatment of mild TBI, penetrating gunshot wounds of the skull and brain, severe TBI, and severe consequences of brain injury, including a vegetative state. In addition, we used the materials of international and national guidelines for the diagnosis, intensive care, and surgical treatment of severe TBI, which were published in recent years. The proposed recommendations for surgical treatment of severe TBI in adults are addressed primarily to neurosurgeons, neurologists, neuroradiologists, anesthesiologists, and intensivists who are routinely involved in treating these patients.

    The objective of this review is to evaluate the evidence regarding the use of music as an adjuvant therapy for pain control in hospitalized adults. The search terms music, music therapy, pain, adults, inpatient, and hospitalized were used to search the Cochrane Library, Cinahl, Medline, Natural Standard, and Scopus databases from January 2005 to March 2011. (A systematic review conducted by the Cochrane Collaboration has extensively covered the time frame from 1966 to 2004.) Seventeen randomized controlled trials met criteria for review and inclusion. Seven of the research studies were conducted with surgical patients, three with medical patients, one with medical-surgical patients, four with intensive care patients, and two with pregnant patients. The combined findings of these studies provide support for the use of music as an adjuvant approach to pain control in hospitalized adults. The use of music is safe, inexpensive, and an independent nursing function that can be easily incorporated into the routine care of patients. PMID:23107431

    Objectives To investigate the effects of a high-intensity functional exercise program on independence in activities of  daily living (ADLs) and balance in older people with dementia and whether exercise effects differed between dementia types. Design Cluster-randomized controlled trial: Umeå Dementia and Exercise (UMDEX) study. Setting Residential care facilities, Umeå, Sweden. Participants Individuals aged 65 and older with a dementia diagnosis, a Mini-Mental State Examination score of 10 or greater, and dependence in ADLs (N = 186). Intervention Ninety-three participants each were allocated to the high-intensity functional exercise program, comprising lower limb strength and balance exercises, and 93 to a seated control activity. Measurements Blinded assessors measured ADL independence using the Functional Independence Measure (FIM) and Barthel Index (BI) and balance using the Berg Balance Scale (BBS) at baseline and 4 (directly after intervention completion) and 7 months. Results Linear mixed models showed no between-group effect on ADL independence at 4 (FIM=1.3, 95% confidence interval (CI)=−1.6–4.3; BI=0.6, 95% CI=−0.2–1.4) or 7 (FIM=0.8, 95% CI=−2.2–3.8; BI=0.6, 95% CI=−0.3–1.4) months. A significant between-group effect on balance favoring exercise was observed at 4 months (BBS=4.2, 95% CI=1.8–6.6). In interaction analyses, exercise effects differed significantly between dementia types. Positive between-group exercise effects were found in participants with non-Alzheimer's dementia according to the FIM at 7 months and BI and BBS at 4 and 7 months. Conclusion In older people with mild to moderate dementia living in residential care facilities, a 4-month high-intensity functional exercise program appears to slow decline in ADL independence and improve balance, albeit only in participants with non-Alzheimer's dementia.

    This paper discusses the development of methods for computer-aided jaw surgery. Computer-aided jaw surgery allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery (CAS) system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3D surface models from Cone-beam CT (CBCT), dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intra-operative guidance. The system provides further intra-operative assistance with the help of a computer display showing jaw positions and 3D positioning guides updated in real-time during the surgical procedure. The CAS system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training and assessing the difficulties of the surgical procedures prior to the surgery. CAS has the potential to make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

The paper also describes the case mix, outcome and activity of the admissions in the Case Mix Programme Database (CMPD). Methods The CMP collects data on consecutive admissions to adult, general critical care units in England, Wales and Northern Ireland. Explicit steps are taken to ensure the accuracy of the data, including use of a dataset specification, of initial and refresher training courses, and of local and central validation of submitted data for incomplete, illogical and inconsistent values. Criteria for evaluating clinical databases developed by the Directory of Clinical Databases were applied to the CMPD. The case mix, outcome and activity for all admissions were briefly summarised. Results The mean quality level achieved by the CMPD for the 10 Directory of Clinical Databases criteria was 3.4 (on a scale of 1 = worst to 4 = best). The CMPD contained validated data on 129,647 admissions to 128 units. The median age was 63 years, and 59% were male. The mean Acute Physiology and Chronic Health Evaluation II score was 16.5. Mortality was 20.3% in the CMP unit and was 30.8% at ultimate discharge from hospital. Nonsurvivors stayed longer in intensive care than did survivors (median 2.0 days versus 1.7 days in the CMP unit) but had a shorter total hospital length of stay (9 days versus 16 days). Results for the CMPD were comparable with results from other published reports of UK critical care admissions. Conclusions The CMP uses rigorous methods to ensure data are complete, valid and reliable. The CMP scores well against published criteria for high-quality clinical databases. PMID:15025784

    This single-center retrospective study aimed to report the impact of early hematopoietic and immune recoveries after a standard total body irradiation, cyclophosphamide, and fludarabine (TCF) reduced-intensity conditioning (RIC) regimen for double umbilical cord blood (dUCB) allogeneic stem cell transplantation (allo-SCT) in adults. We analyzed 47 consecutive patients older than 17 years who engrafted after a dUCB TCF allo-SCT performed between January 2006 and April 2013 in our department. Median times for neutrophil and platelet recoveries were 17 (range, 6 to 59) and 37 days (range, 0 to 164), respectively. The 3-year overall (OS) and disease-free survivals, relapse incidence, and nonrelapse mortality were 65.7%, 57.2%, 27.1%, and 19%, respectively. In multivariate analysis, higher day +30 monocyte (≥615/mm(3); hazard ratio [HR], .04; 95% confidence interval [CI], .004 to .36; P < .01) and day +42 lymphocyte (≥395/mm(3); HR, .16; 95% CI, .03 to .78; P = .02) counts were independently associated with better OS. These results suggest that early higher hematopoietic and immune recovery is predictive of survival after dUCB TCF RIC allo-SCT in adults. Factors other than granulocyte colony-stimulating factor, which was used in all cases, favoring expansion of monocytes or lymphocytes, should be tested in the future as part of the UCB transplantation procedure.

    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

    In this paper we present a detailed analysis of the use of the APACHE II (acute physiological and chronic health evaluation) scoring system on all of the patients admitted to the general intensive care unit at the Bristol Royal Infirmary over a 20-month period. The 6-month survival of 691 adult medical and surgical patients following intensive care was recorded and this data was analysed with admission and daily APACHE II scores using a relational database. Our data confirms the relationship between admission APACHE II scores and outcome, with mean scores decreasing as duration of survival increases. We also demonstrate that the best day one scores are approximately 50% less than the admission score, irrespective of outcome, indicating the benefit of intensive care. By contrast, however, the scores on day one have either not improved or have worsened since admission, reflecting the importance of the pre-morbid health status of the patient in determining outcome from intensive care.

    Fragility fractures typically occur in elderly patients related principally to osteoporosis. A significative percentage of these fractures have to be treated surgically but comorbilities are often present, and need to be grossly stabilized before surgery. However, there is for these fractures a high rate of morbidity and mortality at short-term.

    Pulmonary cystic echinococcosis is a very rare disease in Germany. It is caused by the larvae of the dog tapeworm (echinococcus granulosus). The liver is the most affected organ, followed by the lungs. Surgery remains the main therapeutic approach for pulmonary CE. Whenever possible, parenchyma-preserving lung surgery should be preferred over anatomic lung resections. To ensure best therapeutic results, surgery needs to be performed under precise consideration of important infectiological aspects and patients should be treated in specialised centres based on interdisciplinary consensus. In addition to surgical aspects, this review summarises special infectiological features of this disease, which are crucial to the surgical approach. PMID:26351761

    This paper considers two new elevator and dental forceps techniques for the atraumatic removal of teeth to avoid a surgical procedure where possible. The techniques described should be applicable in relatively well defined but commonly occurring situations. The two techniques involve the unconventional use of conventional dental extraction forceps, with the aim of facilitating removal of the retained roots of certain teeth: the first for incisors, canines and premolars and the second for lower first molars. The term 'surgical forceps technique's is tentatively put forward as a description of these hybrid procedures. PMID:11819949

    Objectives For some oncologic emergencies, surgical interventions are necessary for dissolution or temporary relieve. In the absence of guidelines, the most optimal method for decision making would be in a multidisciplinary cancer conference (MCC). In an acute setting, the opportunity for multidisciplinary discussion is often not available. In this study, the management and short term outcome of patients after surgical oncologic emergency consultation was analyzed. Method A prospective registration and follow up of adult patients with surgical oncologic emergencies between 01-11-2013 and 30-04-2014. The follow up period was 30 days. Results In total, 207 patients with surgical oncologic emergencies were included. Postoperative wound infections, malignant obstruction, and clinical deterioration due to progressive disease were the most frequent conditions for surgical oncologic emergency consultation. During the follow up period, 40% of patients underwent surgery. The median number of involved medical specialties was two. Only 30% of all patients were discussed in a MCC within 30 days after emergency consultation, and only 41% of the patients who underwent surgery were discussed in a MCC. For 79% of these patients, the surgical procedure was performed before the MCC. Mortality within 30 days was 13%. Conclusion In most cases, surgery occurred without discussing the patient in a MCC, regardless of the fact that multiple medical specialties were involved in the treatment process. There is a need for prognostic aids and acute oncology pathways with structural multidisciplinary management. These will provide in faster institution of the most appropriate personalized cancer care, and prevent unnecessary investigations or invasive therapy. PMID:25933135

    Introduction Intussusception is a rare disease in adults and poses a challenge to identify and manage. In adults, surgical resection is the preferred treatment since half are due to malignancy. This case reveals an association between highly active antiretroviral therapy (HAART) and intussusception. Presentation of case A 44 year-old female with history of HIV on highly active antiretroviral therapy (HAART) presented with 3 month history of epigastric pain, nausea, emesis, weight loss, and lactic acidosis. CT of abdomen showed two small bowel intussusceptions and pericolic fat infiltration. A diagnosis of mitochondrial toxicity secondary to HAART medication was made. HAART medication was discontinued with resolution of symptoms. Further work-up to exclude a mechanical cause for her symptoms including colonoscopy, small bowel follow through, esophagogastroduodenoscopy, and repeat CT were performed. All established an absence of malignancy and intussusception. Discussion Mitochondrial toxicity (MT) is a well-known complication of HAART. A hallmark of MT is lactic acidosis which when untreated can be fatal. Although MT is known to cause gastrointestinal symptoms, intussusception has not been previously reported. In our patient with MT, prolonged usage of HAART medication resulted in severe gastrointestinal symptoms and intussusception mimicking a surgical abdomen. Laparotomy has been recommended on adult patients with intussusceptions because of the high likelihood of identifying a pathologic lesion. The doctrine of adult intussusception is to operate for concern of malignancy. Conclusion Surgeons, gastroenterologist and internist caring for patients on HAART therapy must be aware of the possibility of MT when evaluating HIV patients for possible surgical abdomen.

    2013-01-01

    Background Several studies suggest that low 25(OH) vitamin D3 levels may be prognostic in some malignancies, but no studies have evaluated their impact on treatment outcome in acute myeloid leukemia (AML). Methods VD levels were evaluated in 97 consecutive newly diagnosed, intensively-treated AML patients. MicroRNA-expression profiles and single nucleotide polymorphisms (SNPs) in the 25(OH) vitamin D3 pathway genes were evaluated and correlated with 25(OH) vitamin D3 levels and treatment outcome. Results Thirty-four (35%) patients had normal 25(OH) vitamin D3 levels (32–100 ng/ml), 34 (35%) insufficient (20–31.9 ng/ml) and 29 (30%) deficient levels (<20 ng/ml). Insufficient/deficient 25(OH) vitamin D3 levels were associated with worse relapse-free survival (RFS) compared to normal vitamin D3 levels. In multivariate analyses, deficient 25(OH) vitamin D3, smoking, European LeukemiaNet Genetic Groups and white blood cell count retained their statistical significance for RFS. A number of microRNAs and SNPs were found to be associated with 25(OH) vitamin D3 level, although none remained significant after multiple test corrections; one 25(OH) vitamin D3 receptor SNP, rs10783219, was associated with lower complete remission rate (p=0.0442), shorter RFS (p=0.0058) and overall survival (p=0.0011). Conclusions It remains to be determined what role microRNA and SNP profiles play in contributing to low 25(OH) vitamin D3 level and/or outcome and whether supplementation will improve AML outcome.

    At the resuscitation department, 21 patients with psychotic states after surgical intervention were followed up. Time of origination of psychoses following surgical intervention was ascertained together with their duration. There were no cases of development of organic psychoses. Narcosis is considered to be unimportant in the etiology of psychoses as are its particular features. The following items are contributing factors: dread of operation, intense pain in the immediate period after the operation. The incidence of different psychotic syndromes is indicated, the necessity to carry out ultimate investigations is substantiated. PMID:9072232

    Performing a surgical procedure during spaceflight will become more likely with longer duration missions in the near future. Minimal surgical capability has been present on previous missions as the definitive medical care time was short and the likelihood of surgical events too low to justify surgical hardware availability. Early demonstrations of surgical procedures in the weightlessness of parabolic flight indicated the need for careful logistical planning and restraint of surgical hardware. The consideration of human ergonomics also has more impact in weightlessness than in the conventionall-g environment. Three methods of surgical instrument restraint - a Minor Surgical Kit (MSK), a Surgical Restraint Scrub Suit (SRSS), and a Surgical Tray (ST) were evaluated in parabolic flight surgical procedures. The Minor Surgical Kit was easily stored, easily deployed, and demonstrated the best ability to facilitate a surgical procedure in weightlessness. Important factors in this surgical restraint system include excellent organization of supplies, ability to maintain sterility, accessibility while providing secure restraint, ability to dispose of sharp items and biological trash, and ergonomical efficiency.

    Effective handovers are vital to patient safety and continuity of care, and this is recognised by several national bodies including the GMC. The existing model at Great Western Hospital (GWH) involved three general surgical teams and a urology team placing their printed patient lists, complete with weekend jobs, in a folder for the on-call team to collect at the weekend. We recognised a need to reduce time searching for patients, jobs and reviews, and to streamline weekend ward rounds. A unified weekend list ordering all surgical patients by ward and bed number was introduced. Discrepancies in the layout of each team's weekday list necessitated the design of a new weekday list to match the weekend list to facilitate the easy transfer of information between the two lists. A colour coding system was also used to highlight specific jobs. Prior to this improvement project only 7.1% of those polled were satisfied with the existing system, after a series of interventions satisfaction increased to 85.7%. The significant increase in overall satisfaction with surgical handover following the introduction of the unified weekend list is promising. Locating patients and identifying jobs is easier and weekend ward rounds can conducted in a more logical and timely fashion. It has also helped facilitate the transition to consultant ward rounds of all surgical inpatients at the weekends with promising feedback from a recent consultants meeting. PMID:26734294

    Baillie, Colin T; Smith, Jennifer A

    2015-01-01

    Inflammatory bowel disease (IBD) comprises two distinct but related chronic relapsing inflammatory conditions affecting different parts of the gastrointestinal tract. Crohn’s disease is characterised by a patchy transmural inflammation affecting both small and large bowel segments with several distinct phenotypic presentations. Ulcerative colitis classically presents as mucosal inflammation of the rectosigmoid (distal colitis), variably extending in a contiguous manner more proximally through the colon but not beyond the caecum (pancolitis). This article highlights aspects of the presentation, diagnosis, and management of IBD that have relevance for paediatric practice with particular emphasis on surgical considerations. Since 25% of IBD cases present in childhood or teenage years, the unique considerations and challenges of paediatric management should be widely appreciated. Conversely, we argue that the organizational separation of the paediatric and adult healthcare worlds has often resulted in late adoption of new approaches particularly in paediatric surgical practice.

    Study Rationale Cerebral palsy (CP) is a group of nonprogressive syndromes of posture and motor impairment associated with lesions of the immature brain. Spastic quadriplegia is the most severe form with a high incidence of scoliosis, back pain, respiratory compromise, pelvic obliquity, and poor sitting balance. Surgical stabilization of the spine is an effective technique for correcting deformity and restoring sitting posture. The decision to operate in this group of patients is challenging. Objectives The aim of this study is to determine the benefits of surgical correction of scoliosis in children with spastic quadriplegia, the adverse effects of this treatment, and what preoperative factors affect patient outcome after surgical correction. Materials and Methods A systematic review was undertaken to identify studies describing benefits and adverse effects of surgery in spastic quadriplegia. Factors affecting patient outcome following surgical correction of scoliosis were assessed. Studies involving adults and nonspastic quadriplegia were excluded. Results A total of 10 case series and 1 prospective and 3 retrospective cohort studies met inclusion criteria. There was significant variation in the overall risk of complications (range, 10.9−70.9%), mortality (range, 2.8−19%), respiratory/pulmonary complications (range, 26.9−57.1%), and infection (range, 2.5−56.8%). Factors associated with a worse outcome were a significant degree of thoracic kyphosis, days in the intensive care unit, and poor nutritional status. Conclusion Caregivers report a high degree of satisfaction with scoliosis surgery for children with spastic quadriplegia. There is limited evidence of preoperative factors that can predict patient outcome after scoliosis. There is a need for well-designed prospective studies of scoliosis surgery in spastic quadriplegia.

    1980-01-01

    Ease of handling and control in zero gravity and minimizing the quantity of water required were prime considerations. The program tasks include the selection of biocidal agent from among the variety used for surgical scrub, formulation of a dispensing system, test, and delivery of flight dispensers. The choice of an iodophore was based on effectiveness on single applications, general familiarity among surgeons, and previous qualification for space use. The delivery system was a choice between the squeeze foamer system and impregnated polyurethane foam pads. The impregnated foam pad was recommended because it is a simpler system since the squeeze foamer requires some applicator to effectively clean the skin surfaces, whereas the form pad is the applicator and agent combined. Testing demonstrated that both systems are effective for use as surgical scrubs.

    2012-01-01

    Postthrombotic syndrome (PTS) is a late outcome of deep vein thrombosis characterized by cramping pain, swelling, hyperpigmentation, eczema, lipodermatosclerosis, and ulceration in the leg due to increased venous outflow resistance and reflux venous flow. Newer surgical and endovascular interventions have a promising result in the management of postthrombotic syndrome. Early surgical or endovascular interventions in appropriately selected patients may decrease the incidence of recurrent ulceration and skin changes and provide a better quality of life. Duplex and IVUS (intravenous ultrasound) along with venography serve as cornerstone investigative tools for assessment of reflux and obstruction. Venous obstruction, if present, should be addressed earlier than reflux. It requires endovenous stenting, endophlebectomy, or open bypass procedures. Venous stripping, foam sclerotherapy, radiofrequency, or laser ablation are used to abolish superficial venous reflux. Valvuloplasty procedures are useful for incompetent but intact deep venous valves, while transposition or axillary vein autotransplantation is done for completely destroyed valves. PMID:22084674

    Presbyopia, the gradual loss of accommodation that becomes clinically significant during the fifth decade of life, is a physiologic inevitability. Different technologies are being pursued to achieve surgical correction of this disability; however, a number of limitations have prevented widespread acceptance of surgical presbyopia correction, such as optical and visual distortion, induced corneal ectasia, haze, anisometropy with monovision, regression of effect, decline in uncorrected distance vision, and the inherent risks with invasive techniques, limiting the development of an ideal solution. The correction of the presbyopia and the restoration of accommodation are considered the final frontier of refractive surgery. The purpose of this paper is to provide an update about current procedures available for presbyopia correction, their advantages, and disadvantages. PMID:23055664

    2015-04-01

    Surgical mentors have helped trainees develop fulfilling and academically productive careers, while supervisors are formally assigned to impart skills and oversee training. This paper reviews the comparative roles of the supervisor and mentor and how they overlap, while exploring the impact of the 'unknown' mentor. While the supervisor's role in directing the student is formally recognized, the mentee will personally select a mentor who successfully models the career and life balance to which the mentee aspires. The unknown mentor is known only to the mentee. The mentee's commitment to communicating with both mentor and supervisor is crucial to success. Better processes can be used to guide the mentor relationship. Confusion between the two roles - mentor and supervisor - is due to their complementary nature as well as an overlap in roles. Both remain essential to the growth and development of the surgical trainee. The unknown mentor could give detached advice and guidance to the student, while acting as a positive role model.

    Surgical attire helps protect patients from microorganisms that may be shed from the hair and skin of perioperative personnel. The updated AORN "Guideline for surgical attire" provides guidance on scrub attire, shoes, head coverings, and masks worn in the semirestricted and restricted areas of the perioperative setting, as well as how to handle personal items (eg, jewelry, backpacks, cell phones) that may be taken into the perioperative suite. This article focuses on key points of the guideline to help perioperative personnel adhere to facility policies and regulatory requirements for attire. The key points address the potential benefits of wearing scrub attire made of antimicrobial fabric, covering the arms when in the restricted area of the surgical suite, removing or confining jewelry when wearing scrub attire, disinfecting personal items that will be taken into the perioperative suite, and sending reusable attire to a health care-accredited laundry facility after use. Perioperative RNs should review the complete guideline for additional information and for guidance when writing and updating policies and procedures. PMID:25645036

    In July 2000, the da Vinci Surgical System (Intuitive Surgical, Inc) received Food and Drug Administration approval for intracardiac applications, and the first mitral valve repair was done at the East Carolina Heart Institute in May 2000. The system is now approved and used in many surgical specialties. With this disruptive technology and accepted use, surgeons and hospitals are seeking the most efficacious training pathway leading to safe use and responsible credentialing.One of the most important issues related to safe use is assembling the appropriate team of professionals involved with patient care. Moreover, proper patient selection and setting obtainable goals are also important.Creation and maintenance of a successful program are discussed in the article focusing on realistic goals. This begins with a partnership between surgeon leaders, hospital administrators, and industry support. Through this partnership, an appropriate training pathway and clinical pathway for success can be outlined. A timeline can then be created with periods of data analysis and adjustments as necessary. A successful program is attainable by following this pathway and attending to every detail along the journey. PMID:23528718

    Surgical implants have a wide array of therapeutic uses, most commonly in joint replacements, but also in repair of pes excavatum and spinal disorders, in cardiac devices (stents, patches, pacers, valves), in gynecological implants, and in dentistry. Many of the metals used are immunologically active, as are the methacrylates and epoxies used in conjunction with several of these devices. Allergic responses to surgical components can present atypically as failure of the device, with nonspecific symptoms of localized pain, swelling, warmth, loosening, instability, itching, or burning; localized rash is infrequent. Identification of the specific metal and cement components used in a particular implant can be difficult, but is crucial to guide testing and interpretation of results. Nickel, cobalt, and chromium remain the most common metals implicated in implant failure due to metal sensitization; methacrylate-based cements are also important contributors. This review will provide a guide on how to assess and interpret the clinical history, identify the components used in surgery, test for sensitization, and provide advice on possible solutions. Data on the pathways of metal-induced immune stimulation are included. In this setting, the allergist, the dermatologist, or both have the potential to significantly improve surgical outcomes and patient care. PMID:26362550

    Eighty cases of surgically treated syringomyelia were retrospectively reviewed. The cases were classified into following 4 types, type 1: syringomyelia with Chiari malformation (54 cases), type 2: syringomyelia with basal arachnoiditis (15 cases), type 3: syringomyelia with an obstruction of the foramen Magendie (1 case), and type 4: syringomyelia with spinal arachnoiditis (14 cases). Foramen magnum decompression (FMD) was performed in patients with type 1, in type 2 fourth ventricle-subarachnoid shunt was additionally performed. Gardner's operation was performed in patients with type 3. Syrinx-peritoneal shunt was performed in patients with type 4. Surgical procedures for syringomyelia which we selected were thought to be appropriate, based on postoperative syrinx collapse rate in MRI. However, postoperative clinical course was much different in each type of syringomyelia after the collapse of syrinx had been equally achieved. Neurological disorders were stopped in deterioration after surgery in all cases of type 1. However, motor weakness was still deteriorated in half cases of type 2, and in 60% of type 4. When clinical severity of the patients with type 1 and 2, based on the distribution of dissociated sensory loss and motor weakness, were classified into 5 grades. The rate of improvement of patient's symptoms and signs was higher in the lower grades. We concluded that a surgical treatment for syringomyelia was essentially a preventive one, therefore it should be done in early stage of disorders. PMID:8752412

    Recent advances in allogeneic stem cell transplantation (allo-HSCT) have included the advent of reduced-intensity conditioning (RIC) regimens to decrease the toxicity of myeloablative allo-SCT and the use of double umbilical cord blood (dUCB) units as a graft source in adults lacking a suitable donor. The FB2A2 regimen (fludarabine 30 mg/kg/day for 5-6 days + i.v. busulfan 3.6 mg/kg/day for 2 days + rabbit antithymocyte globulin 2.5 mg/kg/day for 2 days) supported by peripheral blood stem cells (PBSCs) and the TCF regimen (fludarabine 200 mg/m² for 5 days + cyclophosphamide 50 mg/kg for 1 day + low-dose [2 Gy] total body irradiation) supported by dUCB units are currently the most widely used RIC regimens in many centers and could be considered standard of care in adults eligible for an RIC allo-SCT. Here we compared, retrospectively, the outcomes of adults patients who received the FB2A2-PBSC RIC regimen (n = 52; median age, 59 years; median follow-up, 19 months) and those who received the dUCB-TCF RIC regimen (n = 39; median age, 56 years; median follow-up, 20 months) for allo-SCT between January 2007 and November 2010. There were no significant between-group differences in patient and disease characteristics. Cumulative incidences of engraftment, acute grade II-IV and chronic graft-versus-host disease were similar in the 2 groups. The median time to platelet recovery, incidence of early death (before day +100), and 2-year nonrelapse mortality were significantly higher in the dUCB-TCF group (38 days versus 0 days [P <.0001]; 20.5% versus 4% [P = .05], and 26.5% versus 6% [P = .02], respectively). The groups did not differ in terms of 2-year overall survival (62% for FB2A2-PBSC versus 61% for dUCB-TCF), disease-free survival (59% versus 50.5%), or relapse incidence (35.5% versus 23%). In multivariate analysis, the presence of a lymphoid disorder was associated with a significantly higher 2-year overall survival (hazard ratio, 0.42; 95% confidence interval, 0

    Gingival recession represents a clinical condition in adults frequently encountered in the general dental practice. Clinicians often face dilemmas of whether or not to treat such a condition surgically. An initial condensed literature search was performed using a combination of gingival recession and surgery controlled terms and keywords. An analysis of the search results highlights the limited understanding of the factors that guide the treatment of gingival recession. Understanding the cause, prognosis, and treatment of gingival recession continues to offer many unanswered questions and challenges in periodontics as we strive to provide the best care possible for our patients.

    2016-08-01

    Malignant pleural mesothelioma (MPM) is associated with a poor prognosis. The main components of multimodality treatment include surgery, chemotherapy, and radiation therapy. Surgery remains controversial. Two procedures are currently offered: extrapleural pneumonectomy (EPP) and pleurectomy/decortication (P/D). The recent scientific literature suggests that P/D is a well-tolerated procedure, with the potential of becoming a default procedure in multimodality regimens. However, the precise treatment schemes and surgical procedures are yet to be established. In our study, we review the advantages and disadvantages of EPP and P/D, summarize the post-EPP and post-P/D observations (including mortality, morbidity, and median survival time), and discuss the choice of surgical technique (EPP vs. P/D). Moreover, we highlight the aspects of the multimodality treatments that are offered to MPM patients, including chemotherapy, radiotherapy, intensity-modulated radiation therapy, and other types of therapy.

    The outcome of children, adolescents and young adults (CAYA) with poor-risk recurrent/refractory lymphoma is dismal (⩽30%). To overcome this poor prognosis, we designed an approach to maximize an allogeneic graft vs lymphoma effect in the setting of low disease burden. We conducted a multi-center prospective study of myeloablative conditioning (MAC) and autologous stem cell transplantation (AutoSCT), followed by a reduced intensity conditioning (RIC) and allogeneic hematopoietic cell transplantation (AlloHCT) in CAYA, with poor-risk refractory or recurrent lymphoma. Conditioning for MAC AutoSCT consisted of carmustine/etoposide/cyclophosphamide, RIC consisted of busulfan/fludarabine. Thirty patients, 16 Hodgkin lymphoma (HL) and 14 non-Hodgkin lymphoma (NHL), with a median age of 16 years and median follow-up of 5years, were enrolled. Twenty-three patients completed both MAC AutoSCT and RIC AlloHCT. Allogeneic donor sources included unrelated cord blood (n=9), unrelated donor (n=8) and matched siblings (n=6). The incidence of transplant-related mortality following RIC AlloHCT was only 12%. In patients with HL and NHL, 10 year EFS was 59.8% and 70% (P=0.613), respectively. In summary, this approach is safe, and long-term EFS with this approach is encouraging considering the poor-risk patient characteristics and the use of unrelated donors for RIC AlloHCT in the majority of cases.

    Despite the wide acceptance of the hepatobiliary scintigraphy as a popular diagnostic imaging modality for gallbladder and hepatobiliary disease, correlation between radionuclide diagnoses and the final clinical and/or pathologic findings have not been thoroughly evaluated. The lack of correlative studies frequently generates difficulties in making appropriate diagnostic interpretation of the objective findings. A retrospective clinical pathological and surgical correlative study was undertaken by the authors in 138 male veteran patients, who underwent computer assisted minute by minute Tc-99m DISIDA cholescintigraphy. A very high percentage (75%) revealed abnormalities; non-visualization of gallbladder (GB) with normal choledochus system (46%), choledochal obstruction with no GB visualization (13%), choledochal obstruction with normal GB visualization (6%), severe hepatocellular disease with non-diagnostic GB (4%), and delayed GB visualization (longer than 60 minutes) (3%). Non-visualization of GB but normal choledochus demonstrated diverse pathologic etiologies, acute and chronic cholecystitis (64%), S/P cholecystectomy (8%), functional obstruction secondary to sepsis or pancreatitis (6%), and various other pathologies including porcelain GB and cholangitis (22%). The most important cause of choledochal obstruction was mass lesions or local infiltration with metastases (33%) rather than acute cholecystitis (27%). Although the sensitivity (98%) and specificity (92%) for cystic duct obstruction were very high, the specificity decreases significantly for cholecystitis.

    OBJECTIVE. A review was performed to investigate the frequency of occurrence and outcome of patients who have retained surgical sponges. METHODS. Closed case records from the files of the Medical Professional Mutual Insurance Company (ProMutual, Boston, MA) involving a claim of retained surgical sponges were reviewed for a 7-year period. RESULTS. Retained sponges occurred in 40 patients, comprising 48% of all closed claims for retained foreign bodies. A falsely correct sponge count after an abdominal procedure was documented in 76% of these claims. Ten percent of claims involved vaginal deliveries and minor non-body cavity procedures, for which no sponge count was performed. Total indemnity payments were $2,072,319, and defense costs were $572,079. In three cases, the surgeon was deemed responsible by the court despite the nursing staff's admitting liability and evidence presented that the surgeon complied completely with the standard of care. A wide range of indemnity payments was made despite a remarkable similarity of outcome in the patients studied. CONCLUSIONS. Despite the rarity of the reporting of a retained surgical sponge, this occurrence appears to be encountered more commonly than generally is appreciated. Operating teams should ensure that sponges be counted for all vaginal and any incisional procedures at risk for retaining a sponge. In addition, the surgeon should not unquestioningly accept correct count reports, but should develop the habit of performing a brief but thorough routine postprocedure wound/body cavity exploration before wound closure. The strikingly similar outcome for most patients would argue for a standardized indemnity payment being made without the need for adversarial legal procedures. PMID:8678622

    Simulation in surgical training is playing an increasingly important role as postgraduate medical education programs navigate an environment of increasing costs of education, increased attention on patient safety, and new duty hour restrictions. In obstetrics and gynecology, simulation has been used to teach many procedures; however, it lacks a standardized curriculum. Several different simulators exist for teaching various routes and aspects of hysterectomy. This article describes how a formal framework of increasing levels of competencies can be applied to simulation in teaching the procedure of hysterectomy. PMID:27521885

    Great variety exists in the indications and techniques recommended for the surgical treatment of syringomyelia-Chiari complex. More recently, magnetic resonance (MR) imaging has increased the frequency of diagnosis of this pathology and offered a unique opportunity to visualize cavities inside the spinal cord as well as their relationship to the cranio-cervical junction. This report presents 18 consecutive adult symptomatic syringomyelia patients with Chiari malformation who underwent foramen magnum decompression and syringosubarachnoid shunting. The principal indication for the surgery was significant progressive neurological deterioration. All patients underwent preoperative and postoperative MRI scans and were studied clinically and radiologically to assess the changes in the syrinx and their neurological picture after surgical intervention. All patients have been followed up for at least 36 months. No operative mortality was encountered; 88.9% of the patients showed improvement of neurological deficits together with radiological improvement and 11.1% of them revealed collapse of the syrinx cavity but no change in neurological status. None of the patients showed further deterioration of neurological function. The experience obtained from this study demonstrates that foramen magnum decompression to free the cerebro-spinal fluid (CSF) pathways combined with a syringosubarachnoid shunt performed at the same operation succeeds in effectively decompressing the syrinx cavity, and follow-up MR images reveal that this collapse is maintained. In view of these facts, we strongly recommend this technique, which seems to be the most rational surgical procedure in the treatment of syringomyelia-Chiari complex. PMID:11189926

    There are two main surgical treatments for osteoarthritis: conservative treatments, where the damaged cartilage is left in place, and radical treatments, where the cartilage is replaced by an artificial endoprosthesis; this latter procedure is termed joint arthroplasty. These treatments are only offered to symptomatic patients. Arthrodesis is yet another surgical intervention in cases of osteoarthritis. It will sacrifice the joint's articular function and is performed on small osteoarthritic joints, such as wrists and ankles, for instance. Osteoarthritis symptoms are usually the consequence of an imbalance between the load applied to a joint and the surface available to support that load. Therefore, conservative treatments will either tend to decrease the load exerted on the joint, such as in a tibial valgus osteotomy for instance, or to improve the articular surface supporting that load. Sometimes, both can be provided at the same time; the peri-acetabular osteotomy for hip dysplasia is an example of such a procedure. Conservative treatments are usually offered to young patients in order to delay, if not avoid, the need for a joint prosthesis. They are usually performed before osteoarthritis appears or at an early stage. Joint arthroplasties have overwhelmingly excellent functional results and today's research is directed towards providing rapid recovery, very long-term stability, and the assurance of a good functionality in extreme conditions. However, complications with joint arthroplasties can be serious with little, if any, reasonable salvage solution. Therefore, these procedures are offered to patients who have failed adequate medical treatment measures. PMID:27185463

    In 2013, a total of 84,332 patients had undergone extracapsular tonsillectomies (TE) and 11,493 a tonsillotomy (TT) procedure in Germany. While the latter is increasingly performed, the number of the former is continually decreasing. However, a constant number of approximately 12,000 surgical procedures in terms of abscess-tonsillectomies or incision and drainage are annually performed in Germany to treat patients with a peritonsillar abscess. The purpose of this part of the clinical guideline is to provide clinicians in any setting with a clinically focused multi-disciplinary guidance through the surgical treatment options to reduce inappropriate variation in clinical care, improve clinical outcome and reduce harm. Surgical treatment options encompass intracapsular as well as extracapsular tonsil surgery and are related to three distinct entities: recurrent episodes of (1) acute tonsillitis, (2) peritonsillar abscess and (3) infectious mononucleosis. Conservative management of these entities is subject of part I of this guideline. (1) The quality of evidence for TE to resolve recurrent episodes of tonsillitis is moderate for children and low for adults. Conclusions concerning the efficacy of TE on the number of sore throat episodes per year are limited to 12 postoperative months in children and 5-6 months in adults. The impact of TE on the number of sore throat episodes per year in children is modest. Due to the heterogeneity of data, no firm conclusions on the effectiveness of TE in adults can be drawn. There is still an urgent need for further research to reliably estimate the value of TE compared to non-surgical therapy of tonsillitis/tonsillo-pharyngitis. The impact of TE on quality of life is considered as being positive, but further research is mandatory to establish appropriate inventories and standardized evaluation procedures, especially in children. In contrast to TE, TT or comparable procedures are characterized by a substantially lower postoperative

    Current treatment approaches in morbid obesity are multimodal in nature. Combination therapies include increases in moderate-intensity aerobic and resistance exercise; behavioral lifestyle changes to increase compliance with diet and activity recommendations; medical nutrition therapy; intensive medical therapy; and metabolic surgical procedures, such as gastric bypass and vertical sleeve gastrectomy. This article focuses on the preoperative evaluation and proper patient selection for metabolic surgery. The procedures are discussed relative to their anatomy, metabolic mechanism of action, and common adverse effects. PMID:26896207

    Neuronavigation and stereotaxy are techniques designed to help neurosurgeons precisely localize different intracerebral pathological processes by using a set of preoperative images (CT, MRI, fMRI, PET, SPECT etc.). The development of computer assisted surgery was possible only after a significant technological progress, especially in the area of informatics and imagistics. The main indications of neuronavigation are represented by the targeting of small and deep intracerebral lesions and choosing the best way to treat them, in order to preserve the neurological function. Stereotaxis also allows lesioning or stimulation of basal ganglia for the treatment of movement disorders. These techniques can bring an important amount of confort both to the patient and to the neurosurgeon. Neuronavigation was introduced in Romania around 2003, in four neurosurgical centers. We present our five-years experience in neuronavigation and describe the main principles and surgical techniques. PMID:20108488

    Surgical procedures for voice restoration serve to improve oral communication by better vocal function. They comprise of phonomicrosurgery, with direct and indirect access to the larynx; laryngoplasty; laryngeal injections; and surgical laryngeal reinnervation. The basis for modern surgical techniques for voice disorders is the knowledge about the ultrastructure of the vocal folds and the increasing experience of surgeons in voice surgery, while facing high social and professional demands on the voice. Vocal activity limitation and participation restriction has become more important in the artistic and social areas. A number of surgical methods that have been developed worldwide for this reason, are presented in this article. Functional oriented surgery has to meet high standards. The diagnostics of vocal function has to be multi-dimensional in order to determine the indication and the appropriate surgical intervention. PMID:22073062

    There was major progress through 2012 in cardiovascular anesthesia and intensive care. Although recent meta-analysis has supported prophylactic steroid therapy in adult cardiac surgery, a large Dutch multicenter trial found no outcome advantage with dexamethasone. A second large randomized trial is currently testing the outcome effects of methyprednisolone in this setting. Due to calibration drift, the logistic EuroSCORE has recently been recalibrated. Despite this model revision, EuroSCORE II still overestimates mortality after transcatheter aortic valve implantation. It is likely that a specific perioperative risk model will be developed for this unique patient population. Recent global consensus has prioritized 12 non-surgical interventions that merit further study for reducing mortality after surgery. There is currently a paradigm shift in the conduct of adult aortic arch repair. Recent advances have facilitated aortic arch reconstruction with routine antegrade cerebral perfusion at mild-to-moderate hypothermia. Further integration of hybrid endovascular techniques may allow future aortic arch repair without hypothermia or circulatory arrest. These advances will likely further improve patient outcomes.

    Esthetic body contouring has become the most common esthetic surgical procedure since the advent of liposuction. The interest in this surgery led us to focus on the physiology of adipose tissue that behaves differently according to its localisation. Besides, a better knowledge of the anatomy of the subcutaneous tissue has helped us to treat the deep and superficial adipose deposits more effectively. Many technical refinements have been proposed in order to improve the results and decrease the risks. Local infiltration allows us to remove large amounts of fat with a minimal blood loss. Syringe aspiration is less traumatic and avoids the purchase of an expensive suction pump. However, although the technique of suction lipectomy looks simple, this procedure can induce important local complications (contour deformities, skin waves, ...) and general complications (pulmonary embolism, fat embolism, cardio-pulmonary decompensation). A rigorous technique, performed by a well trained surgeon in an adequate medical environment is essential to obtain the best results with suction lipectomy. In order to correct excesses of skin on the abdomen or the thighs after an important weight loss, skin excisions will be necessary. In there cases, the scars are often wide and sometimes difficult to hide. PMID:8927853

    The development progress of a precision electro-mechanical instrument which allows the detection and documentation of the forces and moment applied to human tissue during surgery (under actual operation room conditions), is reported. The pen-shaped prototype probe which measures 1/2 inch in diameter and 7 inches in length was fabricated using an aerodynamic balance. The aerodynamic balance, a standard wind tunnel force and moment sensing transducer, measures the forces and the moments transmitted through the surgeon's hand to the human tissue during surgery. The prototype probe which was fabricated as a development tool was tested successfully. The final version of the surgical force detection probe will be designed based on additional laboratory tests in order to establish the full scale loads. It is expected that the final product will require a simplified aerodynamic balance with two or three force components and one moment component with lighter full scale loads. A signal conditioner was fabricated to process and display the outputs from the prototype probe. This unit will be interfaced with a PC-based data system to provide automatic data acquisition, data processing, and graphics display. The expected overall accuracy of the probe is better than one percent full scale.

    The excision of the choledochal cyst with bile drainage through intestinal conduit is a standard operative procedure in the surgical management of choledochal cysts. During the last eight years five patients have been treated with this operation at the University Children's Hospital in Zagreb. All the patients were girls aged from two months to twelve years. The classical triad of pain, jaundice and abdominal mass was observed in only one patient, an eight-year-old girl. The only symptom in infancy was jaundice. Diagnosis was made by abdominal ultrasound, bibliography, CT scan with hepatotropic contrast and in older children by ERCP. Four cysts were type Todani I, and one cyst was Todani type II. The complete excision of the choledochal cyst with the Roux-Y jejunal conduit without antireflux valve was performed. There was neither operative morbidity nor mortality. Three months postoperatively the control ultrasonography and liver laboratory tests were without abnormalities. The routine control which followed did not show episodes of cholangitis, lithiasis, lipid malabsorption, blood clotting abnormalities or growth failure. The complete excision of the cyst with Roux-Y hepaticoenterostomy is an operative treatment with good results in infancy and childhood. PMID:10932533

    Major imperatives regarding quality of patient care and patient safety are impacting surgical care and surgical education. Also, significant emphasis continues to be placed on education and training to achieve proficiency, expertise, and mastery in surgery. Simulation-based surgical education and training can be of immense help in acquiring and maintaining surgical skills in safe environments without exposing patients to risk. Opportunities for repetition of tasks can be provided to achieve pre-established standards, and knowledge and skills can be verified using valid and reliable assessment methods. Also, expertise and mastery can be attained through repeated practice, specific feedback, and establishment of progressively higher learning goals. Simulation-based education and training can help surgeons maintain their skills in infrequently performed procedures and regain proficiency in procedures they have not performed for a period of time. In addition, warm-ups and surgical rehearsals in simulated environments should enhance performance in real settings. Major efforts are being pursued to advance the field of simulation-based surgical education. New education and training models involving validation of knowledge and skills are being designed for practicing surgeons. A competency-based national surgery resident curriculum was recently launched and is undergoing further enhancements to address evolving education and training needs. Innovative simulation-based surgical education and training should be offered at state-of-the-art simulation centers, and credentialing and accreditation of these centers are key to achieving their full potential.

    Surgical intervention is an integral component in the diagnosis and management of mycetoma. Surgical treatment is indicated for small, localised lesions and massive lesions to reduce the mycetoma load and to enable better response to medical therapy. It is also a life-saving procedure in patients with massive disease and sepsis. Surgical options for mycetoma treatment range from a wide local surgical excision to repetitive debridement excisions to amputation of the affected part. Adequate anaesthesia, a bloodless field, wide local excision with adequate safety margins in a suitable surgical facility, and expert surgeons are mandatory to achieve the best surgical outcome. Surgical intervention in mycetoma is associated with considerable morbidity, deformities, and disabilities, particularly in advanced disease. These complications can be reduced by educating patients to seek medical advice earlier when the lesion is small, localised, and amenable to surgery. There is no evidence for mycetoma hospital cross infection. This communication is based on the authors’ experience in managing over 7,200 mycetoma patients treated at the Mycetoma Research Centre, University of Khartoum, Sudan. PMID:27336736

    Violence against hospital personnel is underreported (less than one in five assaults), and accurate statistics as to the rate of violence against hospital personnel are thus difficult to establish. In the psychiatric discipline, an abundance of information has been published regarding violence in the health care setting, but few studies have examined violence outside psychiatric hospitals or by patients not diagnosed with psychiatric ailments. Using a survey that elicits information about workplace violence, we sought to gauge the prevalence of violent acts affecting general hospital workers who treat victims of violence on a daily basis. The survey was completed by a cohort of surgical staff nationwide (475 responses from 57 residency programs). Two hundred and eighty residents reported having witnessed one or more physical attacks, and 179 reported having been attacked. Violent acts were more likely to be committed in a public hospital than a private institution (P = 0.05). As shown in previous research, most attacks occurred in the emergency room (P = 0.01); the wards and parking lot were next in frequency. Women residents were more likely than men to call hospital security to intervene in a potentially violent situation (P = 0.04), and junior residents (postgraduate years 1-4) were more likely to be attacked than senior residents (> or = 5 years) (P = 0.04). The attacker was most likely to be a young black male between ages 19 and 30 (P = 0.01). We found no statistical relationship between the attacker and the victim regarding sex or race. Of the 475 respondents, 470 reported that they carry a gun themselves or know someone in the hospital environment who carries a gun. Images Figure 1. PMID:9291743

    Optimal surgical management of older adults with cancer starts pre-operatively. The surgeon plays a key role in the appropriate selection of patients and procedures, optimisation of their functional status prior to surgery, and provision of more intensive care for those who are at high risk of post-operative complications. The literature, mainly based on retrospective, non-randomised studies, suggests that factors such as age, co-morbidities, pre-operative cognitive function and intensity of the surgical procedure all appear to contribute to the development of post-operative complications. Several studies have shown that a pre-operative geriatric assessment predicts post-operative mortality and morbidity as well as survival in older surgical cancer patients. Geriatricians are used to working in multidisciplinary teams that assess older patients and make individual treatment plans. However, the role of the geriatrician in the surgical oncology setting is not well established. A geriatrician could be a valuable contribution to the treatment team both in the pre-operative stage (patient assessment and pre-operative optimisation) and the post-operative stage (patient assessment and treatment of medical complications as well as discharge planning).

    Context: Current literature has clearly shown that the indications for surgical treatment of clavicle fractures in adults are expanding. Although clavicle fractures in children and adolescents have traditionally been treated nonoperatively, surgical treatment of displaced clavicle fractures may be indicated for adolescent athletes. Evidence Acquisition: A review of relevant articles published between 1970 and 2013 was completed using MEDLINE and the terms clavicle fracture and adolescent athlete. Study Design: Clinical review. Level of Evidence: Level 3. Results: Excellent outcomes and rapid return to competition can be achieved with surgical management of displaced clavicle fractures in the adolescent athlete with high functional demands similar to those of their adult counterparts. Complications include hardware irritation, screw loosening, pin migration, peri-incisional numbness, and refracture. Athletes and families must be counseled regarding complications and potential need for secondary surgery to remove hardware. Conclusion: The adolescent athlete with a displaced, shortened, or comminuted clavicle fracture presents a unique, controversial dilemma for the surgeon. Earlier return to competition can be achieved with surgical management to restore length and alignment and may prevent malunion, nonunion, and poor outcomes. PMID:25984259

    Third nerve paralysis has been known to be associated with a wide spectrum of presentation and other associated factors such as the presence of ptosis, pupillary involvement, amblyopia, aberrant regeneration, poor bell's phenomenon, superior oblique (SO) overaction, and lateral rectus (LR) contracture. Correction of strabismus due to third nerve palsy can be complex as four out of the six extraocular muscles are involved and therefore should be approached differently. Third nerve palsy can be congenital or acquired. The common causes of isolated third nerve palsy in children are congenital (43%), trauma (20%), inflammation (13%), aneurysm (7%), and ophthalmoplegic migraine. Whereas, in adult population, common etiologies are vasculopathic disorders (diabetes mellitus, hypertension), aneurysm, and trauma. Treatment can be both nonsurgical and surgical. As nonsurgical modalities are not of much help, surgery remains the main-stay of treatment. Surgical strategies are different for complete and partial third nerve palsy. Surgery for complete third nerve palsy may involve supra-maximal recession - resection of the recti. This may be combined with SO transposition and augmented by surgery on the other eye. For partial third nerve, palsy surgery is determined according to nature and extent of involvement of extraocular muscles. PMID:27433033

The pathological diagnosis was adult epithelial hepatoblastoma, with free surgical margins. The patient recei-ved a second surgical intervention 5 months later due to early recurrence and died 10 months after the diagnosis due to a new massive recurrence. His definitive diagnosis is histological. Radical surgery is the only treatment that increases survival, but recurrence is frequent. There are no well-defined patterns of adjuvant chemotherapy nor is there any trans-plant experience. PMID:27599957

    Among intracranial meningiomas, falcotentorial meningiomas, occurring at the junction of the falx cerebri and tentorial dural folds, are extremely rare. Because of their deep location, they are surrounded by critical structures, and have been regarded as one of the most challenging lesions for surgical treatment. In this study, we describe our surgical strategy for falcotentorial meningiomas and provide a review of our experience. PMID:27189300

    Surgical approaches to the hand are commonly executed in the treatment of fractures, ligament injuries, and less commonly in the resection of bony tumors. Careful design and execution of these surgical approaches translates into superior functional and aesthetic outcomes. We have provided a thorough review of commonly used approaches to the hand by evaluating each of these approaches in the context of core principles including safety, versatility, preservation of stability, and aesthetic outcomes.

    Pediatric surgical training in the United States remained basically unchanged from the model developed by Ladd and Gross in the 1930s until recently. Standardized curriculum and novel evaluation methods are now being implemented. Pediatric Surgical education is currently undergoing a transition to competency-based evaluation and promotion. Unfortunately, there is little data on the efficacy of these changes. This presents an opportunity for further study of how we conduct training, and how we evaluate and promote our trainees.

    2016-09-01

    A varicocele is an abnormal dilatation and tortuosity of the veins of the spermatic cord. Although varicoceles are common in the general population and are frequently found on routine physical examinations, they represent the most common correctable cause of male factor infertility. Varicoceles are also often incidental findings on imaging studies, particularly scrotal ultrasound. Importantly, not all varicoceles should be treated equally (or at all), and basic guidelines on the evaluation and indications for treatment of adult varicoceles should be reviewed before counseling and treatment. A semen analysis should be obtained for any male patient of reproductive age considering intervention. The adolescent varicocele is managed much differently than the adult varicocele and remains a source of controversy. This review describes the clinical presentation and the evaluation of adult and pediatric varicoceles, and provides guidance on their diagnosis and workup. It also describes options for surgical repair and the success and complication rates associated with each surgical approach, ultimately supporting microsurgical subinguinal varicocele repair as the current surgical standard.

    Pleural infection is a frequent clinical condition. Prompt treatment has been shown to reduce hospital costs, morbidity and mortality. Recent advances in treatment have been variably implemented in clinical practice. This statement reviews the latest developments and concepts to improve clinical management and stimulate further research. The European Association for Cardio-Thoracic Surgery (EACTS) Thoracic Domain and the EACTS Pleural Diseases Working Group established a team of thoracic surgeons to produce a comprehensive review of available scientific evidence with the aim to cover all aspects of surgical practice related to its treatment, in particular focusing on: surgical treatment of empyema in adults; surgical treatment of empyema in children; and surgical treatment of post-pneumonectomy empyema (PPE). In the management of Stage 1 empyema, prompt pleural space chest tube drainage is required. In patients with Stage 2 or 3 empyema who are fit enough to undergo an operative procedure, there is a demonstrated benefit of surgical debridement or decortication [possibly by video-assisted thoracoscopic surgery (VATS)] over tube thoracostomy alone in terms of treatment success and reduction in hospital stay. In children, a primary operative approach is an effective management strategy, associated with a lower mortality rate and a reduction of tube thoracostomy duration, length of antibiotic therapy, reintervention rate and hospital stay. Intrapleural fibrinolytic therapy is a reasonable alternative to primary operative management. Uncomplicated PPE [without bronchopleural fistula (BPF)] can be effectively managed with minimally invasive techniques, including fenestration, pleural space irrigation and VATS debridement. PPE associated with BPF can be effectively managed with individualized open surgical techniques, including direct repair, myoplastic and thoracoplastic techniques. Intrathoracic vacuum-assisted closure may be considered as an adjunct to the standard

    1985-01-01

    Critical surgical illness, commonly accompanied by shock, sepsis, multiple transfusions, and renal failure, is usually associated with low total calcium and/or low or normal ionized calcium. A seminal case of hypercalcemia in a surgical intensive care unit (SICU) patient prompted the review of 100 patients with longer than average SICU days (greater than 12) to determine the incidence, associated factors, and possible etiologies of this condition. Ten patients had elevated measured, and five others had elevated calculated, ionized calcium (5.9 +/- 0.25 mg%), an incidence of 15%. Compared to the 85 patients who did not develop hypercalcemia, this population had a significantly higher frequency of the following: renal failure, dialysis, total parenteral nutrition (TPN) usage greater than 21 days, bacteremic days greater than 1, transfusions greater than 24 units, shock greater than 1 day, SICU days greater than 36, and antibiotics used greater than 7. In addition, this group had significantly more days of hypocalcemia early in their hospital course. There was no difference in sex, age, mortality, or incidence of respiratory failure. Two patients studied in depth had renal failure requiring dialysis and no malignancy, milk-alkali syndrome, hyperthyroidism, or hypoadrenalism. Parathormone (PTH) concentrations were high normal or elevated (N terminal 20 and 21 pg/ml; C terminal 130 microliters Eq/ml and 1009 pg/ml) at the time of elevated calcium (total 9.2 to 14.6 mg%; ionized 4.9 to 8.2 mg%). Immobilization does not increase PTH. In renal failure, PTH elevation is a consequence of hypocalcemia rather than hypercalcemia. Moreover, five patients did not have renal failure. Shock, sepsis, and multiple transfusions containing citrate may lower total and/or ionized calcium and thus stimulate PTH secretion. Whatever the mechanism, approximately 15% of critically ill surgical patients develop hypercalcemia, which may represent a new form of hyperparathyroidism. PMID:3931594

  18. Surgical decisions regarding medically intractable epilepsy.

    1992-01-01

    The neurosurgeon's primary intention in epilepsy care is to cure patients with medically intractable seizures. If cure cannot be achieved, reduction of the frequency and intensity of the seizures may be worthwhile. With these goals, work-up of the patients must be thoroughly carried out to localize the seizure focus and to demarcate surrounding functional brain. Once the seizure focus and pattern are well understood, the surgical decision can be based on a logical and flexible decision tree. Potential complications and past statistics must also enter into the decision process. With these factors combined, the routine and special needs for each patient can be accommodated. The advancing modalities of AVEEG monitoring and imaging, coupled with more sophisticated surgical techniques resulting in predictably good outcomes, have moved surgery for medically intractable epilepsy from a few dedicated centers to universal component of our health care. Increasing numbers of young patients afflicted with this chronic debilitating disease can expect freedom from social and employer ostracism, a chance to drive, and an opportunity for freedom from family or other caretaker dependence. Advancement in this will continue as neurosurgeons blend their knowledge of basic neurobiology and the clinical sciences. PMID:1537203

    Objectives To identify the role and impact of surgical residents on the various activities of a senior (4th year) surgical clerkship, and to explore students’ perceptions of differences between the teaching behaviours of attending physicians and residents. Design A survey by questionnaire. Setting McGill University, Montreal. Method A 67-item questionnaire was administered to fourth-year medical students at the end of their 8-week surgical clerkship. Analysis of the data was performed using the Wilcoxon signed-rank test, Dunn’s multiple comparison test and mean average. Main outcome measures Overall satisfaction with the clerkship, teaching behaviours and teaching of clinical skills and basic principles. Results Overall satisfaction with the clerkship was 6.31 out of 10. Surgical residents were perceived as being significantly more active than the attending staff in 14 out of 15 teaching behaviours. They were also seen as important in teaching certain clinical skills such as suturing, assisting in the operating room and managing emergency situations. They also contributed significantly to teaching the basic principles of surgery such as infections, surgical bleeding and fluid and electrolytes. On a 10-point scale, students felt that more learning was achieved by independent reading, tutorials and residents’ teaching than by other teaching modalities, including attending physicians’ and nurses’ teaching. Conclusions Medical students perceive surgical residents as being significantly more active in their education process than the attending staff. Residents appear to be responsible for teaching various technical and patient management skills necessary for patient care. Along with independent reading and tutorials, resident teaching contributes a significant portion of the medical student’s acquisition of knowledge and appears to contribute to the students’ choice of surgery as a career.

    Introduction: Clavicle fractures represent 2.5% of fractures in adults and almost 44% of shoulder injuries. The treatment is usually non-surgical with good results; however, significantly displaced fractures can be associated with high non-union rate and therefore many would advocate surgical fixation. This is traditionally carried out by direct approach over the clavicle but an infraclavicular approach has also been used for clavicular fixation. The aim of this study was to identify the main indications for surgical intervention at our unit and patient satisfaction following surgery. We also wanted to compare the direct and the infraclavicular surgical approaches in relation to the outcome of surgical intervention. Materials and Methods: Retrospective study looking at all the clavicle fractures managed surgically over 5 years at our department. Information relating to surgical indication, surgical approach, complications, outcome, patient satisfaction, and oxford shoulder score were collected. Results: A total of 35 patients were identified, the majority were males (n = 25) and most (n = 29) were working at the time of injury. The commonest indication for surgery was displacement with shortening (n = 16). The infraclavicular approach was used in the majority of patients (n = 21), the rest (n = 14) had direct incision. Evidence of radiological and union was achieved in all patients after an average of 13 (8-24) weeks. There were no major complications but minor complications were reported in 28% and 19% of cases with direct and infraclavicular approaches, respectively. Plates were removed from six symptomatic patients; infraclavicular (n = 2) and direct approach (n = 4). Four asymptomatic plates were removed on patients’ requests. All patients returned to work (after an average 2.6 months), had good oxford shoulder score between 12-20, regardless of the surgical approach used. All patients except one would recommend it to a friend. Conclusion: Our study showed

    Abstract 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

    2001-03-01

    Two types of systems are available for evacuating the surgical smoke created by electrosurgery and laser surgery: portable and stationary surgical smoke evacuation systems. While portable systems dominate the market today, stationary systems are an alternative worth considering--even though they are still in their infancy, with fewer than 90 systems installed to date. Stationary systems represent a major commitment on the part of the healthcare facility. Several system components must be installed as part of the physical plant (for instance, within the walls), making the system a permanent fixture in the surgical suite. Installation of these systems is often carried out during building construction or major renovation--although the systems can be cost-effective even if no renovations are planned. For this Evaluation, we tested three stationary systems. All three are adequate to capture surgical smoke and evacuate it from the operating room. These systems are easy to use, are quietter than their portable counterparts, and require minimal user maintenance. They represent an excellent option for most hospitals actively evacuating surgical smoke. In this article, we discuss the factors to consider when selecting from among these systems. We also offer guidance on choosing between stationary systems and portable ones. PMID:11321758

    Background The number of malignancies increased alarmingly. Surgery constitutes one of the most efficient therapeutic modalities for the treatment of solid tumors. The neoplastic implant in surgical wound is a complication whose percentage of occurrence reported in the literature is variable, but sets with high morbidity and therapeutic difficulties. Protecting the wound is one of the recommended principles of oncologic surgery. Aim To evaluate the influence of wound protection in the development of tumor implantation. Methods Sarcoma 180 tumor cells were used, with intraperitoneal inoculation in Swiss mice. After the establishment of neoplastic ascites, animals were randomized into two groups of 10, each group consisting of five males and five females. In both groups, laparotomy and manipulation of intra-abdominal organs was performed. In a group laparotomy was performed using the protection of the abdominal wound and the other group without it. On the 9th postoperative day macroscopic evaluation of the operative scar was performed, which was later removed for microscopic evaluation. Results There was microscopic infiltration of tumor cells in the wound of all animals. However, the group that held the protection, infiltration was less intense when compared to the group without it. The infiltration was also more severe in females than in males of the same group. Conclusion Tumor infiltration into the wound was more intense in the group in which the protection of the surgical site was not performed, and in females when compared to males of the same group.

    Background Convergence insufficiency is a common eye muscle co-ordination problem in which the eyes have a strong tendency to drift outward (exophoria) when reading or doing close work. Symptoms may include eye strain, headaches, double vision, print moving on the page, frequent loss of place when reading, inability to concentrate, and short attention span. Objectives To systematically assess and synthesize evidence from randomized controlled trials (RCTs) on the effectiveness of non-surgical interventions for convergence insufficiency. Search strategy We searched The Cochrane Library, MEDLINE, EMBASE, Science Citation Index, the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com) and ClinicalTrials.gov (www.clinicaltrials.gov) on 7 October 2010. We manually searched reference lists and optometric journals. Selection criteria We included RCTs examining any form of non-surgical intervention against placebo, no treatment, sham treatment, or each other. Data collection and analysis Two authors independently assessed eligibility, risk of bias, and extracted data. We performed meta-analyses when appropriate. Main results We included six trials (three in children, three in adults) with a total of 475 participants. We graded four trials at low risk of bias. Evidence from one trial (graded at low risk of bias) suggests that base-in prism reading glasses was no more effective than placebo reading glasses in improving clinical signs or symptoms in children. Evidence from one trial (graded at high risk of bias) suggests that base-in prism glasses using a progressive addition lens design was more effective than progressive addition lens alone in decreasing symptoms in adults. At three weeks of therapy, the mean difference in Convergence Insufficiency Symptoms Survey (CISS) score was −10.24 points (95% confidence interval (CI) −15.45 to −5.03). Evidence from two trials (graded at low risk of bias) suggests that outpatient (or office-based as used in the

    Normal adult zebrafish can completely regenerate lost myocardium following partial amputation of the ventricle apex. We report that 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) significantly impairs this regeneration. Adult male zebrafish were injected with vehicle (control) or TCDD (70ng/g, ip) 1 day prior to partial amputation of the ventricle apex. Gross observation and histological analysis of the amputated heart at 21 days postamputation revealed that TCDD-exposed fish had not progressed beyond the initial clot formation stage, whereas the vehicle control fish showed substantial recovery and almost complete resolution of the formed clot. In contrast, hearts that were not surgically wounded showed no signs of TCDD toxicity. Striking features in the TCDD-exposed hearts were the absence of the normal sheath of new tissue enveloping the wound and the absence of intense cell proliferation at the site of the wound. In addition, the patterns of collagen deposition at the wound site were different between the TCDD and vehicle groups. Because the receptor for TCDD is the aryl hydrocarbon receptor ligand-activated transcriptional regulator, we examined the effects of TCDD exposure on gene expression in the ventricle using DNA microarrays. Samples were collected just prior to amputation and at 6h and 7 days postamputation. TCDD-pretreated hearts had dysregulated expression of genes involved in heart function, tissue regeneration, cell growth, and extracellular matrix. Because embryonic, but not adult, hearts are major targets for TCDD-induced cardiotoxicity, we speculate that the need for embryonic-like cells in regeneration is connected with the effects of TCDD in inhibiting the response to wounding.

    The methods proposed for managing fluids and particulate debris during minor surgery on Space Station Freedom (SSF) were investigated and demonstrated. A KC-135 parabolic flight test was performed, in which the flight followed the standard 40 parabola profile with 20 to 25 seconds in near-zero gravity in each parabola. The equipment (suction and laminar flow device) was evaluated. While this equipment performed satisfactorily previously in the dental simulation, the purpose of the current flight was to reconfigure the equipment in support of a minor surgical situation in order to evaluate its efficacy and establish clear requirements for the actual flight hardware. To accomplish the study the Health Maintenance Facility medical restraint system was deployed as for surgical use and mannequin suture arm was restrained to its surface. The surgical area was established as for performing minor surgery with standard tray and suture instruments employed.

    Endobronchial tumors are a rare entity that presents with different pathological findings. The interventional pulmonologist, but also the thoracic surgeon have at their disposal the same techniques for diagnosis, however; the two modalities differentiate in the treatment approach. Diagnosis evaluation should include lymph node evaluation. Minimal invasive techniques under local or general anesthesia are usually preferred by the interventional pulmonologists, whereas in the surgical approach of the thoracic surgeons the general anesthesia is necessary. A more extensive surgical approach either lobotomy or pneumonectomy should be performed in cases with positive intrapulmonary lymph nodes. Carinal reconstruction should be performed skillfully to get a negative proximal margin whenever needed. In the current manuscript we will present the methods of patient evaluation and surgical techniques for the management of these lesions. PMID:24102010

    Chronic pancreatitis is a progressive inflammatory disease resulting in permanent structural damage of the pancreas. It is mainly characterized by recurring epigastric pain and pancreatic insufficiency. In addition, progression of the disease might lead to additional complications, such as pseudocyst formation or development of pancreatic cancer. The medical and surgical treatment of chronic pancreatitis has changed significantly in the past decades. With regard to surgical management, pancreatic head resection has been shown to be a mainstay in the treatment of severe chronic pancreatitis because the pancreatic head mass is known to trigger the chronic inflammatory process. Over the years, organ-preserving procedures, such as the duodenum-preserving pancreatic head resection and the pylorus-preserving Whipple, have become the surgical standard and have led to major improvements in pain relief, preservation of pancreatic function, and quality of life of patients.

    Many of the contours of a surgical clerkship can be designed, implemented, and evaluated with varying degrees of objectivity. The recently established Association for Surgical Education and its expanding membership have performed in an excellent fashion in addressing the objectives, content, process, and evaluation of surgical clerkships. There are several factors that influence the quality of a clerkship that are not readily subjected to measurement but that have a significant impact on the environment and conduct of clerkships. Criticism, mainly from the academic community, has been directed recently to distortions of the learning process and the continuing use of traditional teaching methods that do not serve medical educational programs and students optimally. More attention should be paid to the principle that a surgical clerkship should be designed to provide an elemental comprehension of the major surgical diseases irrespective of how the students will select multiple specialties for their careers. The quality of a clinical teaching program is influenced in a realistic way by the quality of care provided to the patients. The image of the staff, especially the resident staff, plays an important role in affecting students' incentives, the development of self-discipline, their attitudes toward patients and families, and the ultimate selection of careers. As much responsibility as possible for the diagnosis of disease and the care of patients should be given to students under close supervision and always with the best interests of the patients in mind. The environment of medical schools and teaching hospitals is changing rapidly. The corporate practice of medicine will have an impact on the quality of surgical clerkships, we hope not adversely.

    The transanal approach for rectal resection is a promising approach, because it increases the circumferential radial margin, especially for difficult cases. Meanwhile, functional sequelae are frequent after rectal cancer surgery and are often due to neurological lesions. There is little literature describing surgical anatomy from bottom to top.

    The surgical approach to treating fecal incontinence is complex. After optimal medical management has failed, surgery remains the best option for restoring function. Patient factors, such as prior surgery, anatomic derangements, and degree of incontinence, help inform the astute surgeon regarding the most appropriate option. Many varied approaches to surgical management are available, ranging from more conservative approaches, such as anal canal bulking agents and neuromodulation, to more aggressive approaches, including sphincter repair, anal cerclage techniques, and muscle transposition. Efficacy and morbidity of these approaches also range widely, and this article presents the data and operative considerations for these approaches. PMID:24280402

However, a complete regression has not been observed hitherto. Surgical procedure is dependent on expansion, localisation and type of echinococcosis. Generally, cystectomy is possible and adequate in case of Echinococcus granulosus, in case of Echinococcus multilocularis with its infiltrating growth, a complete healing can only be attained by lobectomy. With the hilus being invaded and obstructive jaundice proceeding, an improvement can be reached by Mebendazol or a palliative endless drainage tube. PMID:4013541

Laparoscopy is the preferred method of access, yet controversy remains regarding the optimal procedure and postoperative management. Generally, salpingostomy is employed with the goal of maintaining fertility, although data to support this tenet are lacking. In most cases, the decision to perform conservative versus radical surgery is on the basis of the patient's history, her desire for future fertility, and surgical findings. The procedures of salpingostomy and salpingectomy, techniques to prevent and control blood loss at the time of surgery, and surgical options for nontubal ectopic pregnancies are reviewed.

    Information Technologies being developed by NASA to assist astronaut-physician in responding to medical emergencies during long space flights are being employed for the improvement of women's health in the form of "smart surgical probe". This technology, initially developed for neurosurgery applications, not only has enormous potential for the diagnosis and treatment of breast cancer, but broad applicability to a wide range of medical challenges. For the breast cancer application, the smart surgical probe is being designed to "see" a suspicious lump, determine by its features if it is cancerous, and ultimately predict how the disease may progress. A revolutionary early breast cancer detection tool based on this technology has been developed by a commercial company and is being tested in human clinical trials at the University of California at Davis, School of Medicine. The smart surgical probe technology makes use of adaptive intelligent software (hybrid neural networks/fuzzy logic algorithms) with the most advanced physiologic sensors to provide real-time in vivo tissue characterization for the detection, diagnosis and treatment of tumors, including determination of tumor microenvironment and evaluation of tumor margins. The software solutions and tools from these medical applications will lead to the development of better real-time minimally-invasive smart surgical probes for emergency medical care and treatment of astronauts on long space flights.

    Wilms tumor (WT) occurs infrequently in adults. Even rarer is adult WT with extension by direct intravascular spread into the right side of the heart. The present report describes a WT with intracaval and intracardiac extension in a 38-year-young man. In addition, thrombus extension above the infrahepatic IVC represents a major technical topic for surgeons because of the possible occurrence of uncontrollable hemorrhages and tumor fragmentation. We report the results of a surgical approach to caval thrombosis including the isolation of the IVC from the liver as routinely performed during liver harvesting. The morphologic and immune-histochemical findings confirmed the diagnosis. PMID:25553532

    The purpose of our research is to develop surgical navigation systems to enhance surgical safety. Our systems make use of augmented reality technology to superimpose, on the surgery screen on a real time basis, patients' organ models reconstructed in 3D from their X-ray CT data taken before surgery. By doing so, the systems display anatomical risk materials, tumors and blood vessels which surgeons cannot see with their naked eyes. This will in turn lead to surgeons intuitively grasping the inner structures of the operational fields. We so far have been developing navigation systems that can conduct surgeries in various fields. The basic structure of the navigation systems are the same. The navigation systems uses different peripheral equipment and different methods to display navigation images which best meet the demands of each type of surgery. In this thesis, we report on our navigation systems for 2 types of surgery - endoscopic sinus surgery and hepatobilialy-pancreatic surgery. PMID:24732545

    One of the major challenges in the development of virtual environments for medical simulations is photorealistic rendering, permitting high fidelity visual effects and user interaction. Digitized videos recorded from the laparoscopic camera are a rich source of information about surgical scenarios. How to fully utilize the information is important for improving the realism of the simulated scenarios. In reality, the camera viewpoint changes frequently and even for the same viewpoint, the scene is dynamic due to rhythmic heartbeat. Hence, the results of classical texture mapping are usually visually unappealing as they fail to capture the pulsatile effect, as well as other global illumination properties of the scene. In this paper we present a hybrid technique to improve the photorealistic rendering of the virtual surgery scenarios by spatio-temporally utilizing videos recorded during actual surgical procedures.

    Surgical correction of tetralogy of Fallot is still one of the most frequently performed intervention in pediatric cardiac surgery, and in many cases, it is far from being a complete and definitive correction. It is rather an excellent palliation that solves the problem of cyanosis, but predisposes the patients to medical and surgical complications during follow-up. The decision-making process regarding the treatment of late sequel is among the most discussed topics in adult congenital cardiology. In post-operative Fallot patients, echocardiography is used as the first method of diagnostic imaging and currently allows both a qualitative observation of the anatomical alterations and a detailed quantification of right ventricular volumes and function, of the right ventricular outflow tract, and of the pulmonary valve and pulmonary arteries. The literature introduced many quantitative echocardiographic criteria useful for the understanding of the pathophysiological mechanisms involving the right ventricle and those have made much more objective any decision-making processes.

    Tracheostomy is a relatively common surgical procedure that is performed easily in an operating room or intensive care unit. Open tracheostomy is needed in patients requiring prolonged ventilation when percutaneous tracheostomy is inappropriate. Sometimes, it is difficult to achieve bleeding control in the peritracheal soft tissue, and in such cases, we usually use diathermy. However, the possibility of an electrocautery-ignited surgical field fire can be overlooked during the procedure. This case report serves as a reminder that the risk of a surgical field fire during tracheostomy is real, particularly in patients requiring high-oxygen therapy. PMID:25346908

    Postoperative nausea and vomiting frequently complicate outpatient anesthesia and surgery. The duration of treatment for this complication must occasionally extend beyond discharge from the hospital. In this study, we evaluated the commonly used anti-emetic promethazine for its efficacy in the post-discharge period. Adult outpatient surgical patients who had excessive postoperative nausea and vomiting in the recovery room, or who were at risk for postoperative nausea and vomiting following discharge were given two promethazine suppositories (25 mg) for home use. All patients were contacted by our recovery room nurses on the first business day after their surgery and questioned as to their use of the suppositories and, if used, their efficacy. We found that 55 percent of patients given promethazine suppositories for home use had nausea and vomiting in the post-discharge period. Of the patients given promethazine, 89 percent used the suppositories. All of these patients reported improvement in their symptoms following use of the suppositories. None reported adverse effects from the promethazine suppositories. In conclusion, we found promethazine suppositories to be an inexpensive and efficacious treatment for nausea and vomiting in adult outpatient surgical patients following discharge from the hospital. Side-effects were minimal, and our patients voiced no complaints about this mode of therapy. We recommend this therapy for treatment of nausea and vomiting after hospital discharge following adult outpatient surgery. PMID:10527366

    There is growing evidence that childhood surgical conditions, especially injuries, are common in developing countries and that poor care results in significant numbers of deaths and cases of disability. Unfortunately, however, surgical care is not considered an essential component of most child health programmes. Strategies for improving paediatric surgical care should be evidence-based and cost-effective and should aim to benefit the largest possible number of children. The most likely way of achieving policy change is to demonstrate that childhood surgical conditions are a significant public health problem. For paediatric purposes, special attention should also be given to defining a cost-effective package of surgical services, improving surgical care at the community level, and strengthening surgical education. Surgical care should be an essential component of child health programmes in developing countries. PMID:12471405

    A teleoperated surgical robotic system allows surgical procedures to be conducted across long distances while utilizing wired and wireless communication with a wide spectrum of performance that may affect the outcome. An open architecture portable surgical robotic system (Raven) was developed for both open and minimally invasive surgery. The system has been the subject of an intensive telesurgical experimental protocol aimed at exploring the boundaries of the system and surgeon performance during a series of field experiments in extreme environments (desert and underwater) teleportation between US, Europe, and Japan as well as lab experiments under synthetic fixed time delay. One standard task (block transfer emulating tissue manipulation) of the Fundamentals of Laparoscopic Surgery (FLS) training kit was used for the experimental protocol. Network characterization indicated a typical time delay in the range of 16-172 ms in field experiments. The results of the lab experiments showed that the completion time of the task as well as the length of the tool tip trajectory significantly increased (alpha< 0.02) as time delay increased in the range of 0-0.5 sec increased. For teleoperation with a time delay of 0.25s and 0.5s the task completion time was lengthened by a factor of 1.45 and 2.04 with respect to no time delay, whereas the length of the tools' trajectory was increased by a factor of 1.28 and 1.53 with respect to no time delay. There were no statistical differences between experienced surgeons and non-surgeons in the number of errors (block drooping) as well as the completion time and the tool tip path length at different time delays.

    The stress response to surgery, critical illness, trauma, and burns encompasses derangements of metabolic and physiological processes that induce perturbations in the inflammatory, acute phase, hormonal, and genomic responses. Hypermetabolism and hypercatabolism result, leading to muscle wasting, impaired immune function and wound healing, organ failure, and death. The surgery-induced stress response is largely similar to that triggered by traumatic injuries; the duration of the stress response, however, varies according to the severity of injury (surgical or traumatic). This spectrum of injuries and insults ranges from small lacerations to severe insults such as large poly-traumatic and burn injuries. Burn injuries provide an extreme model of trauma induced stress responses that can be used to study the long-term effects of a prolonged stress response. Although the stress response to acute trauma evolved to confer improved chances of survival following injury, in modern surgical practice the stress response can be detrimental. PMID:24009246

    The experience of surgical treatment of the pulmonary echinococcosis (PE) at 515 patients is generalized. Character of operative intervention at PE depends on cyst's localization and presence of complications. The method of echinococcectomy with the cappitonnage of fibrous capsule, which is the most effective method of PE surgical treatment, is expounded. The methods of fibrous capsule anti-parasitogenic treatment are described: chemical (10% solution of sodium chloride, chlorhexidinum, betalin), physical (laser radiation, stream of hot air), being most effective, simple and accessible. The methods of videothoracoscopic (VTO) and video-assisted echinococcectomy (VAE), at which application permits the rehabilitation period of patients diminishes considerably, are expounded. The amount of postoperative complications at VTO and VAE made 16.7%, at open echinococcectomy--2.7%. Lethality was 0.2% (one patient died). PMID:19048820

    The aims of surgical treatment in Graves's orbitopathy (GO) are improvement of function and appearance. Since antiinflammatory treatment of GO rarely results in a complete resolution of symptoms, surgical treatment is very important for patients well being. Rehabilitative surgery includes orbital decompression, squint correction, lid lengthening and blepharoplasty and these procedures have to be performed in centres of expertise. Various techniques have been developed for orbital decompression which allow now a graded approach to proptosis reduction and optic nerve decompression in emergency situations. Extraocular muscle recessions can be successfully performed to treat most of the patients with diplopia. Only large or complex squint angles are difficult to treat and step by step procedures are recommended in these patients. Lid lengthening procedures are performed most often in GO patients and should be performed under local anaesthesia to get a good result. Serious complications are rare. PMID:22632370

    Peyronie's disease is a common debilitating condition for both men and their partners that results in penile deformity and compromises sexual functioning. While there are a myriad of medical therapeutic options, these have not been demonstrated to correct the deformity and restore sexual function definitively. As such, surgery is the mainstay of treatment for this disease, and multiple surgical approaches may be considered depending on disease characteristics, patient co-morbidity, and findings on preoperative diagnostic testing. The purpose of this review is to highlight the different surgical approaches and different procedures within each approach, and to examine important issues for surgeons to consider for administering the best treatment that restores function while reconciling patient expectations.

    Testicular torsion is caused by twisting of the spermatic cord, which results in compromised testicular blood flow. The degree of ischemic injury is determined by the severity of arterial compression and the interval between the onset of symptoms and surgical intervention. Torsion usually occurs at puberty, and an anatomic defect known as bell-clapper deformity is usually present. Typical symptoms include acute scrotal pain with associated nausea and vomiting. Up to one-half of patients report previous similar episodes. On examination, the testis is high-riding, tender, swollen and firm. Testicular scan or Doppler ultrasound examination can be helpful in distinguishing torsion from acute epididymitis. Prompt surgical treatment is indicated to reduce the torsion, and bilateral orchiopexy is performed to prevent recurrence. Exocrine function, as determined by semen analysis, is often abnormal after unilateral torsion. 25 references.

    Pediatric epilepsy is a debilitating condition that impacts millions of patients throughout the world. Approximately 20–30% of children with recurrent seizures have drug-resistant epilepsy (DRE). For these patients, surgery offers the possibility of not just seizure freedom but significantly improved neurocognitive and behavioral outcomes. The spectrum of surgical options is vast, ranging from outpatient procedures such as vagus nerve stimulation to radical interventions including hemispherectomy. The thread connecting all of these interventions is a common goal—seizure freedom, an outcome that can be achieved safely and durably in a large proportion of patients. In this review, we discuss many of the most commonly performed surgical interventions and describe the indications, complications, and outcomes specific to each. PMID:27186522

    Monopolar transurethral resection of the prostate (TURP) with endoscopic electrocautery remains the gold standard surgical technique for benign prostatic hypertrophy (BPH) by which all new procedures are compared. We reviewed the current literature, and international urological guidelines and consensus opinion on various surgical options for BPH and present a brief overview of alternative techniques including bipolar TURP, transurethral incision of the prostate, transurethral vaporization of the prostate, laser prostatectomy (with holmium, thulium and potassium titanyl phosphate greenlight lasers) and open prostatectomy (with mention of new techniques including laparoscopic and robotic prostatectomy). Emerging, experimental and less established techniques are also described including endoscopic heat generation (transurethral microwave thermotherapy, radiofrequency transurethral needle ablation of the prostate, high intensity focused ultrasound, hot water induced thermotherapy, pulsed electromagnetic radiofrequency), injection therapy (transurethral ethanol ablation and botulinum toxin) and mechanical devices (intraprostatic stents and urethral lift devices). Despite a plethora of surgical options, none have realistically improved outcomes in the long-term compared with TURP. Improvements have been made on improving surgical morbidity and time in hospital. Questions remain in this area, including what specific elements of bladder outflow obstruction (BOO) result in damage to the urinary tract, how does BPH contribute to BOO and how much prostate volume reduction is necessary to relieve BOO or lower urinary tract symptoms. Given these unanswered questions and the multitude of procedures available, it is clear that appropriate counselling is necessary in all men who undergo BPH surgery. PMID:24744521

    Background Electrocautery, laser tissue ablation, and ultrasonic scalpel tissue dissection all generate a 'surgical smoke' containing ultrafine (<100 nm) and accumulation mode particles (< 1 μm). Epidemiological and toxicological studies have shown that exposure to particulate air pollution is associated with adverse cardiovascular and respiratory health effects. Methods To measure the amount of generated particulates in 'surgical smoke' during different surgical procedures and to quantify the particle number concentration for operation room personnel a condensation particle counter (CPC, model 3007, TSI Inc.) was applied. Results Electro-cauterization and argon plasma tissue coagulation induced the production of very high number concentration (> 100000 cm-3) of particles in the diameter range of 10 nm to 1 μm. The peak concentration was confined to the immediate local surrounding of the production side. In the presence of a very efficient air conditioning system the increment and decrement of ultrafine particle occurrence was a matter of seconds, with accumulation of lower particle number concentrations in the operation room for only a few minutes. Conclusion Our investigation showed a short term very high exposure to ultrafine particles for surgeons and close assisting operating personnel – alternating with longer periods of low exposure.

    Advances over the past decade have indicated that a complex interplay between environmental factors, genetic predisposition, alcohol abuse, and smoking lead towards the development of chronic pancreatitis. Chronic pancreatitis is a complex disorder that causes significant and chronic incapacity in patients and a substantial burden on the society. Major advances have been made in the etiology and pathogenesis of this disease and the role of genetic predisposition is increasingly coming to the fore. Advances in noninvasive diagnostic modalities now allow for better diagnosis of chronic pancreatitis at an early stage of the disease. The impact of these advances on surgical treatment is beginning to emerge, for example, patients with certain genetic predispositions may be better treated with total pancreatectomy versus lesser procedures. Considerable controversy remains with respect to the surgical management of chronic pancreatitis. Modern understanding of the neurobiology of pain in chronic pancreatitis suggests that a window of opportunity exists for effective treatment of the intractable pain after which central sensitization can lead to an irreversible pain syndrome in patients with chronic pancreatitis. Effective surgical procedures exist for chronic pancreatitis; however, the timing of surgery is unclear. For optimal treatment of patients with chronic pancreatitis, close collaboration between a multidisciplinary team including gastroenterologists, surgeons, and pain management physicians is needed.

    A virtual intraoperative surgical photoacoustic microscopy at 1064 nm wavelength (VISPAM) system was designed and fabricated by integrating a commercial type surgical microscope and laser scanning photoacoustic microscopy (PAM) with a 1064 nm pulsed laser. Based on simple augmented reality device, VISPAM could simultaneously provide 2D depth-resolved photoacoustic and magnified microscope images of surgery regions on the same vision of surgeon via an eyepiece of the microscope. The invisible 1064 nm laser removed the interruption of surgical sight due to visible laser scanning of previous report, and decreased the danger of tissue damage caused by over irradiated laser. In addition, to approach the real practical surgery application, a needle-type transducer was utilized without a water bath for PA signal coupling. In order to verify our system's performance, we conducted needle guiding as ex vivo phantom study and needle guiding and injection of carbon particles mixtures into a melanoma tumor region as in vivo study. We expect that VISPAM can be essential tool of brain and ophthalmic microsurgery.

Although MDTs have been widely accepted as the preferred model for cancer service delivery, the process of decision making has not been well described and there is little evidence pointing to the ideal structure of an MDT. Performance in surgery has been shown to depend on non-technical skills, such as decision making, as well as patient factors and the technical skills of the healthcare team. Application of this systems approach to MDT working allows the identification of factors that affect the quality of decision making for cancer patients. In this article we review the literature on decision making in surgical oncology and by drawing from the systems approach to surgical performance we provide a framework for understanding the process of decision making in MDTs. Technical factors that affect decision making include the information about patients, robust ICT and video-conferencing equipment, a minimum dataset with expert review of radiological and pathological information, implementation and recording of the MDTs decision. Non-technical factors with an impact on decision making include attendance of team members at meetings, leadership, teamwork, open discussion, consensus on decisions and communication with patients and primary care. Optimising these factors will strengthen the decision making process and raise the quality of care for cancer patients. PMID:20719499

    Objective. Over the past decade, multiple factors have changed the pattern of neonatal surgical emergencies. An increase in prenatal screenings and the development of neonatal tertiary care centres have changed the clinical approach to these kids. Materials and methods. Between 1995 to 2011 were retrospectively reviewed 34 patients with diagnosis of uncommon rare neonatal surgical emergencies at our institute. We analyzed: sex, gestational age, weight at birth, primary pathology, prenatal diagnosis, associated anomalies, age and weight at surgery, clinical presentation, start of oral feeding and hospitalization. The follow-up was performed at 6,12, 24 and 36 months. Results. There were 21 male and 13 female. The gestational age ranged between 28 and 36 weeks. The weight at birth ranged between 700 and 1400 grams. Oral feeding was started between 4th and 10th postoperative day. The average hospitalization was about 70.47 days. To date, all patients have finished the followup. They are healthy. Conclusion. The outcome of the patients with uncommon surgical emergencies is different based on the etiology. Overall survival is generally good but is influenced by the associated anomalies. PMID:25669890

    The reduction in time for training at the workplace has created a challenge for the traditional apprenticeship model of training. Simulation offers the opportunity for repeated practice in a safe and controlled environment, focusing on trainees and tailored to their needs. Recent technological advances have led to the development of various simulators, which have already been introduced in surgical training. The complexity and fidelity of the available simulators vary, therefore depending on our recourses we should select the appropriate simulator for the task or skill we want to teach. Educational theory informs us about the importance of context in professional learning. Simulation should therefore recreate the clinical environment and its complexity. Contemporary approaches to simulation have introduced novel ideas for teaching teamwork, communication skills and professionalism. In order for simulation-based training to be successful, simulators have to be validated appropriately and integrated in a training curriculum. Within a surgical curriculum, trainees should have protected time for simulation-based training, under appropriate supervision. Simulation-based surgical education should allow the appropriate practice of technical skills without ignoring the clinical context and must strike an adequate balance between the simulation environment and simulators.

  10. Ethical issues in surgical innovation.

    Innovation is responsible for most advances in the field of surgery. Innovative approaches to solving clinical problems have significantly decreased morbidity and mortality for many surgical procedures, and have led to improved patient outcomes. While innovation is motivated by the surgeon's expectation that the new approach will be beneficial to patients, not all innovations are successful or result in improved patient care. The ethical dilemma of surgical innovation lies in the uncertainty of whether a particular innovation will prove to be a "good thing." This uncertainty creates challenges for surgeons, patients, and the healthcare system. By its very nature, innovation introduces a potential risk to patient safety, a risk that may not be fully known, and it simultaneously fosters an optimism bias. These factors increase the complexity of informed consent and shared decision making for the surgeon and the patient. Innovative procedures and their associated technology raise issues of cost and resource distribution in the contemporary, financially conscious, healthcare environment. Surgeons and institutions must identify and address conflicts of interest created by the development and application of an innovation, always preserving the best interest of the patient above the academic or financial rewards of success. Potential strategies to address the challenges inherent in surgical innovation include collecting and reporting objective outcomes data, enhancing the informed consent process, and adhering to the principles of disclosure and professionalism. As surgeons, we must encourage creativity and innovation while maintaining our ethical awareness and responsibility to patients. PMID:24728580

  1. The importance and provision of oral hygiene in surgical patients.

    PubMed

    Ford, Samuel J

    2008-10-01

    The provision of mouth care on the general surgical ward and intensive care setting has recently gained momentum as an important aspect of patient care. Oropharyngeal morbidity can cause pain and disordered swallowing leading to reluctance in commencing or maintaining an adequate dietary intake. On the intensive care unit, aside from patient discomfort and general well-being, oral hygiene is integral to the prevention of ventilator-associated pneumonia. Chlorhexidine (0.2%) is widely used to decrease oral bacterial loading, dental bacterial plaque and gingivitis. Pineapple juice has gained favour as a salivary stimulant in those with a dry mouth or coated tongue. Tooth brushing is the ideal method of promoting oral hygiene. Brushing is feasible in the vast majority, although access is problematic in ventilated patients. Surgical patients undergoing palliative treatment are particularly prone to oral morbidity that may require specific but simple remedies. Neglect of basic aspects of patient care, typified by poor oral hygiene, can be detrimental to surgical outcome. PMID:18947816

    ABSTRACT OBJECTIVE : To investigate the influence of patients' age on the delay between diagnosis and surgical treatment of proximal femoral fractures METHODS : This is a retrospective study, con-ducted at a tertiary university hospital, including all patients admitted with proximal femoral fractures between March 2013 and March 2014. The participants were categorized into four groups according to age levels. The groups were compared according to demographics, comorbidities, fracture type, trau-ma circumstances, and time between diagnosis and surgical procedure RESULTS : One hundred and sixty one patients were included, 37 adults and 124 elderly. Among adults, the mean delay between diagnosis and surgical procedure was 6.4±5.3 days; among elderly the delay was 9.5±7.6 days. There was a progressive increase in the delay from the young-adults group through the elderly individuals (Kruskal-Wallis: 13.7; p=0.003) CONCLUSION : In spite of being the patients most susceptible to complications due to surgical delay, the elderly individuals pre-sented the longest delays from admission to surgical treatment.

    Adult degenerative cervical kyphosis is a debilitating disease that often requires complex surgical management. Young spine surgeons, residents, and fellows are often confused as to which surgical approach to choose due to lack of experience, absence of a systematic method of surgical management, and today's plethora of information regarding surgical techniques. Although surgeons may be able to perform anterior, posterior, or combined (360°) approaches to the cervical spine, many struggle to rationally choose an appropriate approach for deformity correction. The authors introduce an algorithm based on morphology and pathology of adult cervical kyphosis to help the surgeon select the appropriate approach when performing cervical deformity surgery. Cervical deformities are categorized into 5 different prevalent morphological types encountered in clinical settings. A surgical approach tailored to each category/type of deformity is then discussed, with a concrete case illustration provided for each. Preoperative assessment of kyphosis, determination of the goal for surgery, and the complications associated with cervical deformity correction are also summarized. This article's goal is to assist with understanding the big picture for surgical management in cervical spinal deformity. PMID:24785487

The rehabilitation of severe class III adult patients requires a complex interdisciplinary orthodontic and orthognathic approach. This presentation aims to show a case of combination of camouflage and bilateral sagittal split osteotomy (BSSO).Camouflage in maxillary arch was accepted after analysing visual treatment objective (VTO) and pleasing soft tissue compensation which gave us the clue to go ahead for surgical correction of excess mandibular length to achieve best aesthetic outcome while maintaining nature's compensation in upper arch.

    Introduction Surgical education has become one of the most important directions in modern surgery evolution. To meet growing need for appropriate training in laparoscopic and, even more importantly, classic surgical skills, a curriculum involving contemporary tuition methods is needed. Advanced, structuralised training, which includes advanced technologies like virtual reality training, video coaching and motivative aspects of competition, seems to be important for an adequate education programme. Material and methods In academic years 2009/2010 and 2010/2011 the Department of General, Endocrine and Transplant Surgery of the Medical University of Gdansk together with the Pomeranian Foundation for Progress in Surgery organized 4480 h of training in that area of classic (2744) and laparoscopic (1736) skills. Both groups were involved in the programme of training in which the two most important aspects were reliable evaluation of the results and effective motivation to work. Skill evaluation at different stages of the programme were based on completion time and quality measurements. Apart from that, at the end of the course, the participants completed a questionnaire on their subjective perspective on this innovative curriculum, the quality and stability of the skills they obtained. Results In both arms of the programme (laparoscopic and classic) a statistically significant improvement was obtained as early as after the second and third sessions in half of the exercises. The acquired skills were stable over time, as proved by the plateau of completion time achieved in 11 out of 12 exercises. The results of the post-training questionnaire revealed that the participants were very satisfied with the structuralised form of training and appreciated the motivational role of competition. Conclusions Contemporary surgical training should be organized as a systematic, well-evaluated and goal-oriented programme similar to the one proposed by our team. The use of contemporary

    We used a cognitive architecture (ACT-R) to explore the procedural learning of surgical tasks and then to understand the process of perceptual motor learning and skill decay in surgical skill performance. The ACT-R cognitive model simulates declarative memory processes during motor learning. In this ongoing study, four surgical tasks (bimanual carrying, peg transfer, needle passing, and suture tying) were performed using the da Vinci© surgical system. Preliminary results revealed that an ACT-R model produced similar learning effects. Cognitive simulation can be used to demonstrate and optimize the perceptual motor learning and skill decay in surgical skill training. PMID:21335834

    Recent advances in surgical corrections and supportive care for congenital heart disease have resulted in increasing numbers of adult survivors who may develop hematological malignancies. Treatments including chemotherapy for such patients may cause serious hemodynamic or cardiac complications, especially in those receiving stem cell transplantation. We present a 29-year-old woman with acute lymphoblastic leukemia and congenital heart disease. She had been diagnosed with pulmonary atresia with an intact ventricular septum at birth, and the anomaly was surgically corrected according to the Fontan technique at age 9 years. Her induction chemotherapy required modifications due to poor cardiac status with Fontan circulation. However, after surgical procedures including total cavopulmonary connection and aortic valve replacement at first complete remission, her cardiac status was significantly improved. Subsequently, she underwent cord blood stem cell transplantation at the third complete remission. She required intensive supportive care for circulatory failure as a pre-engraftment immune reaction and stage III acute graft versus host disease of the gut, but recovered from these complications. She was discharged on day 239, and remained in complete remission at 1-year post-transplantation. PMID:27599417

    Objectives To assess the compliance of Asian intensive care units and hospitals to the Surviving Sepsis Campaign’s resuscitation and management bundles. Secondary objectives were to evaluate the impact of compliance on mortality and the organisational characteristics of hospitals that were associated with higher compliance. Design Prospective cohort study. Setting 150 intensive care units in 16 Asian countries. Participants 1285 adult patients with severe sepsis admitted to these intensive care units in July 2009. The organisational characteristics of participating centres, the patients’ baseline characteristics, the achievement of targets within the resuscitation and management bundles, and outcome data were recorded. Main outcome measure Compliance with the Surviving Sepsis Campaign’s resuscitation (six hours) and management (24 hours) bundles. Results Hospital mortality was 44.5% (572/1285). Compliance rates for the resuscitation and management bundles were 7.6% (98/1285) and 3.5% (45/1285), respectively. On logistic regression analysis, compliance with the following bundle targets independently predicted decreased mortality: blood cultures (achieved in 803/1285; 62.5%, 95% confidence interval 59.8% to 65.1%), broad spectrum antibiotics (achieved in 821/1285; 63.9%, 61.3% to 66.5%), and central venous pressure (achieved in 345/870; 39.7%, 36.4% to 42.9%). High income countries, university hospitals, intensive care units with an accredited fellowship programme, and surgical intensive care units were more likely to be compliant with the resuscitation bundle. Conclusions While mortality from severe sepsis is high, compliance with resuscitation and management bundles is generally poor in much of Asia. As the centres included in this study might not be fully representative, achievement rates reported might overestimate the true degree of compliance with recommended care and should be interpreted with caution. Achievement of targets for blood cultures

    Mid-line sternotomy is the routine approach for surgical repair of congenital heart diseases. However, its noticeable scar is a constant reminder of having undergone heart surgery. Several alternative approaches have been developed for simple cardiac conditions to hide the scar. Our series, consisting of 26 patients with axillary closure of atrial septal defect, is presented. The median age was 5.45 years (range 3-13), and median weight was 19.84 Kg. (range 13-37). The defect was closed directly in 13 cases, and with an autologous pericardial patch in the other 13. The number of surgical steps and time taken were the same as in median sternotomy. Functional recovery, intensive care unit stay, and hospital discharge were also standard. The cosmetic result, assessed both by patients and relatives, was excellent. PMID:23462094

    Harrington, Lawrence Kent

    Two psychophysical measurement techniques, flicker photometry and successive heterochromatic brightness matching, were used to measure changes in luminance efficiency functions with increasing levels of light adaptation. Both measurement techniques were performed using the same optical system and the same seven healthy adults as subjects. Measurements were taken at four reference stimulus intensities, 1, 10, 100 and 1000 foot-lamberts. Luminous efficiency was found to depend on both the technique and the reference stimulus intensity with which the measurements were taken. For heterochromatic brightness matching, luminous efficiency increased for longer wavelengths as reference intensity increased. Peak luminous efficiency shifted from approximately 540nm to greater than 600nm with increasing intensity for all seven subjects. Peak luminous efficiency was constant for flicker photometry across all intensities but the function narrowed slightly at 100 foot-lamberts.

    To evaluate fungal microbiota in air-conditioning units installed in intensive care units in two university hospitals in Cuiaba city, Mato Grosso, central western region of Brazil, 525 solid environmental samples were collected, 285 from Hospital A and 240 from Hospital B. Collections were performed using sterile swabs on air-conditioning unit components: cooling coils, ventilators, and filters. Mycelial fungi identification was achieved by observation of the macroscopic and micromorphological characteristics in different culture mediums (maize meal, oatmeal and potato dextrose agars and malt extract) using the Ridell technique. Eleven genera and 27 distinct species belonging to the hyphomycetes and ascomycetes classes were isolated and identified. The most frequently detected genera in both hospitals were Aspergillus spp, Penicillium spp, and Cladosporium spp. Values for colony-forming units per gram were 64 and 75%, well above the limits recommended by Health Ministry resolution 176/00 at the locations selected for analysis in Hospitals A and B, respectively. In conclusion, evaluation of fungal microbiota in the air-conditioning units indirectly determined that the air quality was compromised in both university hospitals analyzed, which constitutes a risk factor for the acquisition of infection in the intensive care units.

    Traditional department-based surgical interest groups in Russian medical schools are useful tools for student-based selection of specialty training. They also form a nucleus for initiating research activities among undergraduate students. In Russia, the Departments of Topographical Anatomy and Operative Surgery play an important role in initiating student-led research and providing learners with advanced, practical surgical skills. In tandem with department-led activities, student surgical interest groups prepare learners through surgical competitions, known as "Surgical Olympiads," which have been conducted in many Russian centers on a regular basis since 1988. Surgical Olympiads stimulate student interest in the development of surgical skills before graduation and encourage students to choose surgery as their postgraduate specialty. Many of the participants in these surgical Olympiads have become highly qualified specialists in general surgery, orthopedic surgery, neurosurgery, urology, gynecology, and emergency medicine. The present article emphasizes the role of student interest groups and surgical Olympiads in clinical anatomical and surgical undergraduate training in Russia. PMID:25688979

    Adult intussusception is a relatively infrequent, but well documented entity in the Western surgical literature, where the majorities of cases is caused by tumors and require resection. In Africa and other tropical locations, however, other causes of adult intussusceptions predominate and must be considered. As Western trained surgeons increasingly volunteer in developing countries it is imperative to become familiar with the complex presentation and differential diagnosis of this disease. We present an illustrative case of adult intussusception with a complex differential diagnosis that we recently treated during a surgical mission to the Democratic Republic of Congo. PMID:24949698

    The Cox-maze procedure for the restoration of normal sinus rhythm, initially developed by Dr. James Cox, underwent several iterations over the years. The main concept consists of creating a series of transmural lesions in the right and left atria that disrupt re-entrant circuits responsible for propagating the abnormal atrial fibrillation rhythm. The left atrial appendage is excluded as a component of the Maze procedure. For the first three iterations of the Cox- maze procedure, these lesions were performed using a surgical cut-and-sew approach that ensured transmurality. The Cox-Maze IV is the most currently accepted iteration. It achieves the same lesion set of the Cox- maze III but uses alternative energy sources to create the transmural lesions, potentially in a minimally invasive approach on the beating heart. High-frequency ultrasound, microwave, and laser energy have all been used with varying success in the past. Today, bipolar radiofrequency heat or cryotherapy cooling are the most accepted sources for creating linear lesions with consistent safety and transmurality. The robust and reliable nature of these energy delivery methods has yielded a success rate reaching 90% freedom from atrial fibrillation at 12 months. Such approaches offer a significant long-term advantage over catheter-based ablation, especially in patients having longstanding, persistent atrial fibrillation with characteristics such as dilated left atrial dimensions, poor ejection fraction, and failed catheter ablation. Based on these improved results, there currently is significant interest in developing a hybrid ablation strategy that incorporates the superior transmural robust lesions of surgical ablation, the reliable stroke prevention potential of epicardial left atrial appendage exclusion, and sophisticated mapping and confirmatory catheter-based ablation technology. Such a minimally invasive hybrid strategy for ablation may lead to the development of multidisciplinary "Afib teams" to

    Hyperglycemia has been found to be associated with increased morbidity and mortality in surgical patients, yet, the optimal glucose management strategy during the perioperative setting remains undetermined. While much has been published about hyperglycemia and cardiac surgery, most studies have used widely varying definitions of hyperglycemia, methods of insulin administration, and the timing of therapy. This has only allowed investigators to make general conclusions in this challenging clinical scenario. This review will introduce the basic pathophysiology of hyperglycemia in the cardiac surgery setting, describe the main clinical consequences of operative hyperglycemia, and take the reader through the published material of intensive and conservative glucose management. Overall, it seems that intensive control has modest benefits with adverse effects often outweighing these advantages. However, some studies have indicated differing results for certain patient subgroups, such as non-diabetics with acute operative hyperglycemia. Future studies should focus on distinguishing which patient populations, if any, would optimally benefit from intensive insulin therapy. PMID:26879308

    Objective To compare surgical management and case-fatality rates of intracerebral hemorrhage (ICH) in 1988 and 2005. Methods We identified all adult residents (age ≥18) from the five-county Greater Cincinnati region hospitalized with ICH in 1988 and 2005. Demographics, severity of illness, ICH volume, ICH location, rates and timing of surgery, and 30-day case-fatality were compared between the 1988 and 2005 groups. Results In 1988, 171 ICH patients met study criteria (67 lobar, 80 deep cerebral, 10 brainstem, 14 cerebellar), and in 2005, 259 ICH patients met criteria in (91 lobar, 123 deep cerebral, 19 brainstem, and 26 cerebellar). In 1988, 16% of the patients had surgical removal of their ICH versus 7% in 2005 (p=0.003). In both 1988 and 2005, patients treated with surgery were younger (p<0.001) and had a higher percentage of cerebellar hemorrhages than non-surgical patients. Timing of surgery was similar in 1988 and 2005. In 1988, 30-day case fatality was 32% in surgical patients versus 50% in non-surgical patients (p=0.06). In 2005, 30-day case-fatality was 16% (surgical) versus 45% (non-surgical) (p=0.02). Conclusion The frequency of surgery for ICH was lower in 2005 than in 1988, which may reflect recent clinical trial data showing no benefit for surgery over medical management. ICH case-fatality was essentially the same in 1988 and 2005. Innovative clinical trials to improve ICH outcomes are warranted. PMID:19057323

    The University of Rochester, Department of Surgery, in response to an experimental community-wide limit on hospital budgets, studied high-cost general surgical patients as a potential source of leverage for containment of hospital costs. It was found that a small number of patients impact significantly on hospital costs. In 1980, 3935 patients at Strong Memorial Hospital (SMH) had at least one contact with a general surgical patient care or intensive care unit; 261 patients (6.6%) had total 1980 charges of more than $20,000 each. They contributed 32% of the total of both general surgical charges and patient days. A subset of 2021 patients was selected to represent more precisely the general surgical patient. The 85 high-cost patients (4.2%) of this subset were chosen for intensive study. These patients generated a significant and disproportionate per cent of total (2021) general surgical charges (26.8%) and hospital days (27.6%). Average total charges were more than 8 times those of the complementary general surgical subset (1936). Nineteen of the 85 patients (22.3%) died in the hospital and 42 patients (49.4%) were dead within 2 1/2 years. Forty patients (of the 85) were then further identified as "complex", based on multiple, usually unrelated, illnesses and multiple annual admissions. Tending to be elderly with poor prognoses, 60% of them had died by April 1983. The major criterion of complexity was the lack of a well-focused medical problem; the cure for one problem simply relinquished primacy to another. A parallel study of hospital ancillary procedures disclosed a similar high-cost pattern. Of approximately 4000 ancillary procedures, 100 (2.5%) had annual charges of $100,000 or over, accounting for two-thirds of total 1980 ancillary charges. Roughly 20% of a single patient's ordered procedures accounted for 80% of the patient's ancillary charges, thus allowing concentrated study of a relatively small number of charges.

    The ability to generate 3-dimensional volumetric images of the maxillofacial area has allowed surgeons to evaluate anatomy before surgery and plan for the placement of implants in ideal positions. However, the ability to transfer that information to surgical reality has been the most challenging part of implant dentistry. With the advent of computer-assisted surgery, the surgeon may now navigate through the entire implant procedure with extremely high accuracy. A new portable laptop navigated system for oral implantology is discussed as an adjunct for complex implant cases. PMID:16569960

    Sarcomas are rare cancers of mesenchymal cell origin that include many histologic subtypes and molecularly distinct entities. For primary resectable sarcoma, surgery is the mainstay of treatment. Despite treatment, approximately 50% of patients with soft tissue sarcoma are diagnosed with or develop distant metastases, significantly affecting their survival. Although systemic therapy with conventional chemotherapy remains the primary treatment modality for those with metastatic sarcoma, increased survival has been achieved in select patients who receive multimodality therapy, including surgery, for their metastatic disease. This article provides an overview of the literature on surgical management of pulmonary and hepatic sarcoma metastases. PMID:27542649

    Lesson plans in surgery enable trainers and trainees to agree on goals that balance training needs with service commitments. Lesson plans are individualised to the trainee and encourage ownership of learning. They are based on SMART criteria and therefore have a sound educational footing. Most of the work in creating a lesson plan falls to the trainee. The total time for creation of each plan is approximately 20 min. Our use of lesson plans for surgical training has been met with favourable response from both trainer and trainees. PMID:17550516

    Background. A new influenza A/H1N1 (pH1N1) virus emerged in April 2009, proceeded to spread worldwide, and was designated as an influenza pandemic. A/H1N1 viruses had circulated in 1918–1957 and 1977–2009 and were in the annual vaccine during 1977–2009. Methods. Serum antibody to the pH1N1 and seasonal A/H1N1 viruses was measured in 579 healthy adults at enrollment (fall 2009) and after surveillance for illness (spring 2010). Subjects reporting with moderate to severe acute respiratory illness had illness and virus quantitation for 1 week; evaluations for missed illnesses were conducted over holiday periods and at the spring 2010 visit. Results. After excluding 66 subjects who received pH1N1 vaccine, 513 remained. Seventy-seven had reported with moderate to severe illnesses; 31 were infected with pH1N1 virus, and 30 with a rhinovirus. Determining etiology from clinical findings was not possible, but fever and prominent myalgias favored influenza and prominent rhinorrhea favored rhinovirus. Tests of fall and spring antibody indicated pH1N1 infection of 23% had occurred, with the rate decreasing with increasing anti-pH1N1 antibody; a similar pattern was seen for influenza-associated illness. A reducing frequency of pH1N1 infections was also seen with increasing antibody to the recent seasonal A/H1N1 virus (A/Brisbane/59/07). Preexisting antibody to pH1N1 virus, responses to a single vaccine dose, a low infection-to-illness ratio, and a short duration of illness and virus shedding among those with influenza indicated presence of considerable preexisting immunity to pH1N1 in the population. Conclusions. The 2009 A/H1N1 epidemic among healthy adults was relatively mild, most likely because of immunity from prior infections with A/H1N1 viruses. PMID:22075792

    Since the introduction of cardiac surgery, the prospects for children born with a cardiac defect have improved spectacularly. Many reach adulthood and the population of adults with congenital heart disease is increasing and ageing. However, repair of congenital heart disease does not mean cure. Many adults with congenital heart disease encounter late complications. Late morbidity can be related to the congenital heart defect itself, but may also be the consequence of the surgical or medical treatment or longstanding alterations in hemodynamics, neurodevelopment and psychosocial development. This narrative review describes the cardiac and non-cardiac long-term morbidity in the adult population with congenital heart disease. PMID:27451323

Complete surgical resection has been proposed as the treatment of choice. We describe a case of adult ER that manifested as a nasopharyngeal mass. The diagnosis was made by transnasal endoscopic biopsy, and the patient was managed conservatively. We discuss the current knowledge regarding the clinical presentation, diagnosis, and treatment of adult ER of the parapharyngeal space, and we propose a new concept for treating this tumor nonsurgically in appropriately selected patients.

    Increasing evidence suggests that two factors significantly influence outcome in a surgical emergency – premorbid health and the degree of inflammation during the first 24 h following trauma. Repeat observations suggest that the depth of post-trauma immunoparalysis reflects the height of early inflammatory response. Administration to surgical emergencies, as was routine in the past, of larger amounts of fluid and electrolytes, fat, sugar and nutrients seems counterproductive as it increases immune dysfunction, impairs resistance to disease and, in fact, increases morbidity. Instead, strong efforts should be made to limit the obvious superinflammation, which occurs during the first 24 h after trauma and, thereby, reduce the subsequent immuno-paralysis. paralysis. Several approaches show efficacy in limiting early superinflammation such as strict control of blood glucose, avoida nce of stored blood when possible, supply of antioxidants, live lactic acid bacteria and plant fibres. This review focuses mainly on use of live lactic acid bacteria and plant fibres, often called synbiotics. Encouraging experience is reported from clinical trials in liver transplantation, severe pancreatitis and extensive trauma. Immediate control of inflammation by enteral nutrition and supply of antioxidants, lactic acid bacteria and fibres is facilitated by feeding tubes, introduced as early as possible on arrival at the hospital.

    The presence of immune infiltration of tumour deposits and the existence of effective in vitro anti-tumour immune responses would suggest the possibility of therapeutic manipulation against tumour cells. However, clinical immunotherapy has shown little promise as a cancer treatment. Numerous explanations for this inefficacy have been proposed, one of which involves the elaboration of immunosuppressive moieties from tumour cells. The results of studies presented below show that serum from patients with gastrointestinal and other tumours have immunosuppressive influences on normal lymphocytes. The degree of this in vitro inhibition is related to tumour 'bulk' and may reflect a systemic immunosuppressive influence of the tumour. Isolation and culture of lymphocytes from gastrointestinal tumour deposits demonstrated that these immune cells are functionally inert, suggesting the existence of an immunosuppressive tumour microenvironment. The isolation and partial purification of an immunosuppressive moiety from conditioned culture medium of a variety of human tumour cell lines further supports the hypothesis of tumour-mediated immunosuppression. A number of protein tumour cell products have been described with potent immunosuppressive properties. These include transforming growth factor-beta, interleukin-10, and the retroviral envelope protein p15E. The surgical implications of the proposed tumour-host immune relationship includes the hypothesis that clinically apparent disease may not be amenable to immune attack owing to tumour-mediated immune suppression. The use of immunostimulatory strategies as adjuvant perioperative therapy would seem a more effective environment for the activation of antitumour immune responses in the surgical patient.

    Abstract Neurilemmoma commonly occurs from the fourth to sixth decades of life with an incidence of 3 to 10 per 100,000 people, and is rare in adolescence. This case report describes the clinical and radiographic features of 2 rare cases with intraspinal neurilemmoma of the cervical and thoracic spine. A 29-year-old man who experienced middle back pain with prominent right lower limb weakness, and an 11-year-old boy who suffered from sudden onset neck pain with left arm weakness and hand clawing for 2 weeks before admission to our department were included in this case report. Magnetic resonance imaging of both patients revealed an intraspinal mass causing spinal cord compression at the cervical and thoracic spine. The patients subsequently received urgent posterior spinal cord decompression and tumor resection surgery. The histopathology reports revealed neurilemmoma. The 2 patients recovered and resumed their normal lives within 1 year. Intraspinal neurilemmoma is rare but should be considered in the differential diagnosis of spinal cord compression. Advances in imaging techniques and surgical procedures have yielded substantially enhanced clinical outcomes in intraspinal neoplasm cases. Delicate preoperative study and surgical skill with rehabilitation and postoperative observation are critical. PMID:25654395

    Since the late 1980s, the US Army has been deploying forward surgical teams to the most intense areas of conflict to care for personnel injured in combat. The forward surgical team is a 20-person medical team that is highly mobile, extremely agile, and has relatively little need of outside support to perform its surgical mission. In order to perform this mission, however, team training and trauma training are required. The large majority of these teams do not routinely train together to provide patient care, and that training currently takes place at the US Army Trauma Training Center (ATTC). The training staff of the ATTC is a specially selected 10-person team made up of active duty personnel from the Army Medical Department assigned to the University of Miami/Jackson Memorial Hospital Ryder Trauma Center in Miami, Florida. The ATTC team of instructors trains as many as 11 forward surgical teams in 2-week rotations per year so that the teams are ready to perform their mission in a deployed setting. Since the first forward surgical team was trained at the ATTC in January 2002, more than 112 forward surgical teams and other similar-sized Department of Defense forward resuscitative and surgical units have rotated through trauma training at the Ryder Trauma Center in preparation for deployment overseas.

    2015-01-01

    The Cox-maze procedure for the restoration of normal sinus rhythm, initially developed by Dr. James Cox, underwent several iterations over the years. The main concept consists of creating a series of transmural lesions in the right and left atria that disrupt re-entrant circuits responsible for propagating the abnormal atrial fibrillation rhythm. The left atrial appendage is excluded as a component of the Maze procedure. For the first three iterations of the Cox- maze procedure, these lesions were performed using a surgical cut-and-sew approach that ensured transmurality. The Cox-Maze IV is the most currently accepted iteration. It achieves the same lesion set of the Cox- maze III but uses alternative energy sources to create the transmural lesions, potentially in a minimally invasive approach on the beating heart. High-frequency ultrasound, microwave, and laser energy have all been used with varying success in the past. Today, bipolar radiofrequency heat or cryotherapy cooling are the most accepted sources for creating linear lesions with consistent safety and transmurality. The robust and reliable nature of these energy delivery methods has yielded a success rate reaching 90% freedom from atrial fibrillation at 12 months. Such approaches offer a significant long-term advantage over catheter-based ablation, especially in patients having longstanding, persistent atrial fibrillation with characteristics such as dilated left atrial dimensions, poor ejection fraction, and failed catheter ablation. Based on these improved results, there currently is significant interest in developing a hybrid ablation strategy that incorporates the superior transmural robust lesions of surgical ablation, the reliable stroke prevention potential of epicardial left atrial appendage exclusion, and sophisticated mapping and confirmatory catheter-based ablation technology. Such a minimally invasive hybrid strategy for ablation may lead to the development of multidisciplinary “Afib teams

    The objective was to determine the role of dose intensive induction chemotherapy in patients with soft tissue sarcomas (STS) that were considered unresectable. Treatment consisted of 2-3 cycles of doxorubicin (Dox) and ifosfamide (Ifo) followed by high dose chemotherapy with ifosfamide, carboplatin, etoposide (HD-ICE) plus peripheral blood stem cell transplantation (PBSCT). 30 out of 631 consecutive patients, median age 46 years (21-62), with high grade STS were included. 29 patients completed at least 2 cycles of Dox/Ifo. HD-ICE was withheld because of progressive disease (PD) in 5 patients, neurotoxicity in 6 cases, insufficient peripheral blood stem cell (PBSC) mobilization, complete remission (CR) and refusal in 1 patient each. HD-ICE was associated with non-haematological grade III toxicity including emesis, mucositis, fever, neurotoxicity, and transaminase level elevation. Two additional patients attained a partial response after HD-ICE. Overall, 24 of 30 (80%) patients underwent surgery, with complete tumor resections in 19 patients (63% of all patients, 79% of the operated subgroup); however, 2 of these required amputation. After a median follow up period of 50 months in surviving patients (range, 26-120), 5-year PFS and OS rates were 39% and 48%, respectively. Induction chemotherapy plus consolidation HD-ICE is generally feasible, but is associated with significant neurotoxicity. The advantage of HD-ICE over conventional dose chemotherapy plus external beam radiation therapy (EBRT) in non-resectable disease remains unproven. PMID:24091981

    Background Existing risk stratification tools have limitations and clinical experience suggests they are not used routinely. The aim of this study was to develop and validate a preoperative risk stratification tool to predict 30-day mortality after non-cardiac surgery in adults by analysis of data from the observational National Confidential Enquiry into Patient Outcome and Death (NCEPOD) Knowing the Risk study. Methods The data set was split into derivation and validation cohorts. Logistic regression was used to construct a model in the derivation cohort to create the Surgical Outcome Risk Tool (SORT), which was tested in the validation cohort. Results Prospective data for 19 097 cases in 326 hospitals were obtained from the NCEPOD study. Following exclusion of 2309, details of 16 788 patients were analysed (derivation cohort 11 219, validation cohort 5569). A model of 45 risk factors was refined on repeated regression analyses to develop a model comprising six variables: American Society of Anesthesiologists Physical Status (ASA-PS) grade, urgency of surgery (expedited, urgent, immediate), high-risk surgical specialty (gastrointestinal, thoracic, vascular), surgical severity (from minor to complex major), cancer and age 65 years or over. In the validation cohort, the SORT was well calibrated and demonstrated better discrimination than the ASA-PS and Surgical Risk Scale; areas under the receiver operating characteristic (ROC) curve were 0·91 (95 per cent c.i. 0·88 to 0·94), 0·87 (0·84 to 0·91) and 0·88 (0·84 to 0·92) respectively (P < 0·001). Conclusion The SORT allows rapid and simple data entry of six preoperative variables, and provides a percentage mortality risk for individuals undergoing surgery. PMID:25388883

    Introduction Atrial septal defects (ASDs) are one of the most common congenital malformations in adults. Correction of ASDs in advanced age remains controversial, even though beneficial effects in this patient group were found in recent studies. In older patients, less invasive transcatheter closure of ASDs has been recommended. Aim The aim of this study was to analyze our advanced age ASD surgical cohort: early and late results. Material and methods Retrospective analysis of 32 patients operated on at an age of ≥ 60 years (i.e. age 66.13 ± 4.8, range from 60 to 78) in our center between 2001 and 2011 was carried out. We reviewed our experience of surgical ASD closure in elderly patients over a 10-year period to assess the effects of this type of treatment on early postoperative and long-term survival, early and late complications, preoperative and postoperative clinical status (New York Heart Association [NYHA] functional class), pulmonary hypertension (PH) and atrial arrhythmias. The patients were divided into two groups according to age. Results The frequency of comorbidities was lower in younger age group patients (11 [61%] vs. 13 [93%], p < 0.05). Atrial fibrillation/flutter was found in 21 (66%) of all patients. Late postoperative mortality was higher in the older patient group (3 [21%] vs. 1 [5.6%]). Despite this, we observed significant improvement of symptoms and functional ability in the older population after surgical ASD closure (group I, n = 10 [56%] vs. group II, n = 12 [86%]). Conclusions Surgical correction of clinically significant ASD is effective even in older patients with comorbidities. PMID:26336455

    Background Vulval intraepithelial neoplasia (VIN) is a pre-malignant condition of the vulval skin. This uncommon chronic skin condition of the vulva is associated with a high risk of recurrence and the potential to progress to vulval cancer. The condition is complicated by its’ multicentric and multifocal nature. The incidence of this condition appears to be rising particularly in the younger age group. There is a lack of consensus on the optimal surgical treatment method. However, the rationale for surgical treatment of VIN has been to treat symptoms and exclude underlying malignancy with the continued aim of preservation of vulval anatomy and function. Repeated treatments affect local cosmesis and cause psychosexual morbidity thus impacting on the patients’ quality of life. Objectives To evaluate the effectiveness and safety of surgical interventions for high grade VIN. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Issue 3, 2010, Cochrane Gynaecological Cancer Group Trials Register, MEDLINE and EMBASE up to September 2010. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Selection criteria Randomised controlled trials (RCTs) that compared surgical interventions, in adult women diagnosed with high grade vulval intraepithelial neoplasia. Data collection and analysis Two review authors independently abstracted data and assessed risk of bias. Main results We found only one RCT which included 30 women that met our inclusion criteria and this trial reported data on carbon dioxide laser (CO2 laser) versus ultrasonic surgical aspiration (USA). There was no statistically significant difference in the risk of disease recurrence after one year follow-up, pain, presence of scarring, dysuria or burning, adhesions, infection, abnormal discharge and eschar between women who received CO2 laser and those who received USA.

    Training competent and professional surgeons efficiently and effectively requires innovation and modernization of educational methods. Today's medical learner is quite adept at using multiple platforms to gain information, providing surgical educators with numerous innovative avenues to promote learning. With the growth of technology, and the restriction of work hours in surgical education, there has been an increase in use of simulation, including virtual reality, robotics, telemedicine, and gaming. The use of simulation has shifted the learning of basic surgical skills to the laboratory, reserving limited time in the operating room for the acquisition of complex surgical skills". PMID:26612021

    Pain is a major postoperative symptom in many oral surgical procedures. It is a complex and variable phenomenon that can be influenced by many factors. Good management of oral surgical pain requires a detailed understanding of the pathogenesis of surgical pain. This article aims at reviewing postoperative pain from a broad perspective by looking into the nociception, neuroanatomy, neurophysiology, and neuropharmacology of pain. Therapeutic recommendations are made after reviewing the evidence from the literature for maximizing the efficacy of pain management techniques for oral surgical pain. PMID:12722900

    With recent advances in surgical technology such as preoperative imaging, neuro-monitoring, and surgical instruments, the surgical resectability of intracranial meningiomas has increased over the last two decades. This study reviewed clinical articles regarding the surgical treatment of meningiomas to clarify the role of surgical excision, with a focus on skull base meningiomas. We sub-classified clinical articles about skull base meningiomas into two categories (anterior and middle fossa meningiomas; and posterior fossa meningiomas) and reviewed papers in each category. In cases with anterior and middle fossa meningiomas, surgical resectability has reached a sufficient level to maximize functional preservation. In cases of posterior fossa meningioma, however, surgical respectability remains insufficient even with full use of recent surgical modalities. Continuous refining of operative procedures is required to obtain more satisfactory outcomes, especially for posterior fossa meningioma. In addition, recent long-term outcomes of stereotactic radiosurgery (SRS) were acceptable for controlling the skull base meningiomas. Therefore, combination with surgical excision and SRS should be considered in complicated skull base meningiomas. PMID:27076382

    Robot-assisted radical prostatectomy (RARP) for the patients with localized prostate cancer is increasingly being adopted around the world. The da Vinci surgical system (Intuitive Surgical, Sunnyvale, CA, USA) provides the advantages of simplification and precision of exposure and suturing because of allowing movements of the robotic arm in real time with increased degree of freedom and magnified 3-dimensional view. Therefore, RARP has been expected to provide superior therapeutic benefit to patients in terms of surgical outcome to open or laparoscopic radical prostatectomy. In this review, we provide our technical aspects and tips and tricks of RARP to improve surgical outcome and postoperative quality of life. PMID:26793888

    The importance of protocols for preoperative antisepsis of the hands is given by the risk of transferring bacteria from the hands of the surgical team to the patient during surgery and it is relationship with infection of surgical wound site (SSI). Careful surgical scrub reduces the number of bacteria on the skin, but does not eliminate them completely, remaining transient microorganisms on hands after the surgical scrub. There fore if micropuncture in surgical gloves occurs, the correct preoperative preparation of hands and double gloving will be essential to reduce the risk of bacterial transmission to patients. The protocols for surgical hand antisepsis are two: Surgical scrub with antiseptic soap (hand scrubbing). Surgical scrub by rubbing alcohol (handrubbing). The hand antisepsis by rubbing with an alcohol solution has proved to be significantly more effective compared to soap solutions. We must also see that in surgical hand antisepsis with soap, you must rinse them with water. And often hospitals' taps and keys are contaminated by Pseudomonas spp., including P. aeuinosa.

    Primary care physicians and specialists are frequently involved in the care of surgical patients. Changes in reimbursement have prompted re-examination of preoperative testing and health care expenditures. Physicians have additional incentives to improve health care delivery and reduce costs. The perioperative surgical home concept involves coordinating all aspects of patient care, including behavioral modifications, during the perioperative period. Evidence-based guidelines on preoperative evaluation are available to assist practitioners in managing cardiovascular disease, and communicating surgical risks. Shared decision making in the preoperative period can improve surgical outcomes and patient satisfaction. PMID:27443045

    Craniopharyngioma is a rare and mostly benign epithelial tumor of the sellar and suprasellar region. Two principal patterns of craniopharyngioma are recognized: papillary and adamantinomatous. Papillary craniopharyngiomas are encountered in adults and may lack the cystic spaces filled with "motor oil" as well as the palisading peripheral rows of epithelial cells, keratinization, or calcification typical of pediatric adamantinomatous craniopharyngioma. Secondary to their anatomic location, craniopharyngiomas may present with endocrinologic dysfunction and visual disturbances. Differential diagnosis includes Rathke's cleft cyst, pituitary adenoma, dermoid/epidermoid cysts, and other rare sellar/suprasellar lesions as pituicytomas. Many controversies exist concerning the preferred surgical approach for these tumors. Endoscopic endonasal surgery is no longer reserved only for sellar or small cystic suprasellar lesions. Prechiasmatic/preinfundibular lesions are effectively removed using an endonasal transtuberculum/transplanum approach; subchiasmatic/transinfundibular tumors require the addition of a transellar approach with inferior pituitary transposition; and retrochiasmatic/retroinfundibular lesions are better accessed performing an endonasal superior pituitary transposition. Compared with well-established trancranial approaches (pterional, subfrontal, presigmoid), endoscopic endonasal surgery combines the virtues of the caudocranial and midline approaches, allowing for appropriate infrachiasmatic exposure without the need for manipulation of surrounding neurovascular structures to access the tumor. This anatomic advantage, combined with high-definition wide-angle visualization, exquisite endonasal microsurgical techniques, and devoted instrumentation facilitates a high rate of endocrine function preservation and visual improvement, while concurrently achieving comparable resections.

    Our objective was to evaluate high-intensity focused ultrasound (HIFU) for minimizing blood loss during surgery by hemodynamically isolating large portions of solid organs before their resection. A high-power HIFU device (in-situ intensity of 9000 W/cm2, frequency of 3.3 MHz) was used to produce a wall of cautery for sealing of blood vessels along the resection line in surgically-exposed solid organs (liver lobes, spleen and kidneys) of eight adult pigs. Following HIFU application, the distal portion of the organ was excised using a scalpel. If any blood vessels were still bleeding, additional HIFU application was used to stop the bleeding. The resection was achieved in 6.0 ± 1.5 min (liver), 3.6 ± 1.1 min (spleen) and 2.8 ± 0.6 min (kidneys) of HIFU treatment time, with no occurrence of bleeding for up to 4 hours (until sacrifice). The coagulated region at the resection line had average width of 3 cm and extended through the whole thickness of the organ (up to 4 cm). Blood vessels of up to 1 cm in size were occluded. This method holds promise for future clinical applications in resection of solid tumors and hemorrhage control from high-grade organ injuries. PMID:17498864

    Our active research project DFG Eu-49/1-2 strives to the reconstruction of bone defects basing on the individual craniofacial implants prefabricated within the TICC-processing-chain. In cases of disease of the bone the defect is to plan and the bone has to be resected. The planning of the defect is done on CT- and CAD-data. The common visualisation of this different data-types (CT-data as pixel- or voxel-data on the one hand and CAD-data as geometry-data on the other hand) was not possible in the used application. The development of "Surgical Operation Planning" (SOP) results in an application between CT-visualisation and CAD-application and allows the common visualisation and planning for defect reconstructions.

    South, Fredrick A.; Marjanovic, Marina; Boppart, Stephen A.

    The global incidence of cancer is rising, putting an increasingly heavy burden upon health care. The need to effectively detect and treat cancer is one of the most significant problems faced in health care today. Effective cancer treatment typically depends upon early detection and, for most solid tumors, successful removal of the cancerous tumor tissue via surgical procedures. Difficulties arise when attempting to differentiate between normal and tumor tissue during surgery. Unaided visual examination of the tissue provides only superficial, low-resolution information and often with little visual contrast. Many imaging modalities widely used for cancer screening and diagnostics are of limited use in the operating room due to low spatial resolution. OCT provides cellular resolution allowing for more precise localization of the tumor tissue. It is also relatively inexpensive and highly portable, making it well suited for intraoperative applications.

    2016-06-01

    There have been major advances in the surgery for oesophageal atresia (OA) and tracheo-oesophageal fistula(TOF) with survival now exceeding 90%. The standard open approach to OA and distal TOF has been well described and essentially unchanged for the last 60 years. Improved survival in recent decades is most attributable to advances in neonatal anaesthesia and perioperative care. Recent surgical advances include the use of thoracoscopic surgery for the repair of OA/TOF and in some centres isolated OA, thereby minimising the long term musculo-skeletal morbidity associated with open surgery. The introduction of growth induction by external traction (Foker procedure) for the treatment of long-gap OA has provided an important tool enabling increased preservation of the native oesophagus. Despite this, long-gap OA still poses a number of challenges, and oesophageal replacement still may be required in some cases. PMID:27217220

    Surgical exposures for complex injuries about the elbow are technically demanding because of the high density of neurologic, vascular, and ligamentous elements around the elbow. The posterior approaches (ie, olecranon osteotomy, triceps-reflecting, triceps-splitting, triceps-reflecting anconeus pedicle flap, paratricipital) include techniques used to navigate the area around the triceps tendon and anconeus muscle. These approaches may be extended to gain access to the entire joint. The ulnar nerve, the anterior and posterior capsules, and the coronoid process are addressed by means of a medial approach. Lateral approaches are useful in addressing pathology at the radial head, capitellum, coronoid process, and anterior and posterior capsules. These approaches may be combined to address complex pathology in the setting of fracture fixation, arthroplasty, and capsular release. PMID:19411644

In this period of time there were much more patients diagnosed with this pathology, but the need for surgery was establish very tight regarding the actual practical guide which impose the identification and interception of physiological mechanisms by the surgical procedure. We highlight the particular technical details, as well as the important differences of postoperatory complications according to the topography of the diverticula pouch. PMID:21523958

    Fourteen patients with aspergilloma (fungus ball) were reviewed. Hemoptysis was the major symptom (93%). Chest roentgenograms disclosed a "fungus ball" in every patient, and the mycelia of Aspergillus fumigatus were recovered from all resected specimens. One of three patients treated by pneumonectomy died post-operatively. A lobectomy was performed in ten patients, and segmental resection in one without mortality or significant morbidity. There has been no evidence of recurrence in a follow up of six months to ten years. On the basis of this experience and a review of the literature, excision of a solitary "fungus ball" is recommended when the diagnosis is made. Non-surgical therapy should be reserved for patients whose general medical status or pulmonary reserved prohibit resection. Images Fig. 1. Fig. 2a. Fig. 2b. Fig. 3. Fig. 4. PMID:327952

    Medical therapy with dopaminergic agonists (DAs) has been used for several decades for the treatment of both micro- and macroprolactinomas, without much differentiation between the two conditions. While most cases respond well to DAs in terms of prolactin normalization and control of tumor growth, DAs are often needed for many years, or even for lifetime. Concerns have been raised recently about the possible side effects of long-term use of these medications on the anatomy and function of the heart valves. While macroprolactinomas are rarely surgically curable, pituitary surgery in expert hands is a safe and effective method to permanently cure microprolactinomas, with long-term cure rates around 70 %. In this article, I will review the data on safety of DAs an on the effectiveness and safety of surgery, and I will make an argument that surgery should be offered as a possible therapy to microprolactinoma patients, provided that an experienced pituitary neurosurgeon is available.

    Although nephrectomy by open surgery is the most used technique for the extraction of kidney transplants in the living donor, nephrectomy under laparaoscopy is increasingly practiced. Laparoscopic nephrectomy is less invasive and performed under videoscopy control, after insufflation of the peritoneal cavity. Three to four incisions are done in order to enter the surgical instruments. The kidney is extracted through a horizontal sus-pubic incision. The exposition is either exclusively transperitoneal, retroperitoneal or hand assisted. The advantages of laparoscopy are esthetical, financial due to a shorter hospitalisation and a quicker recovery, as well a confort for the donor. The disadvantages are a longer warm ischemia time and possibly a higher risk of delayed graft function. Randomised studies having compared laparoscopy and open surgery in the living donor have not find any significant difference regarding the per- and perioperative in the complications. PMID:18160357

    Surgical laboratory in pregraduate students in medicine is beneficial and improves learning processes in cognitive aspects and skills acquisition. It is also an early initiation into scientific research. The laboratory is the introductory pathway into basic concepts of medical science (meaningful learning). It is also where students gain knowledge in procedures and abilities to obtain professional skills, an interactive teacher-student process. Medicine works rapidly to change from an art to a science. This fact compromises all schools and medical faculties to analyze their actual lesson plans. Simulators give students confidence and ability and save time, money and resources, eliminating at the same time the ethical factor of using live animals and the fear of patient safety. Multimedia programs may give a cognitive context evolving logically with an explanation based on written and visual animation followed by a clinical problem and its demonstration in a simulator, all before applying knowledge to the patient.

    Adults with learning disabilities (LD) attending adult basic education, GED programs, or community colleges are among the lowest performers on measures of literacy. For example, on multiple measures of reading comprehension, adults with LD had a mean reading score at the third grade level, whereas adults without LD read at the fifth grade level. In addition, large numbers of adults perform at the lowest skill levels on quantitative tasks. Clearly, significant instructional challenges exist for adults who struggle with literacy issues, and those challenges can be greater for adults with LD. In this article, the literature on adults with LD is reviewed, and evidenced-based instructional practices that significantly narrow the literacy achievement gap for this population are identified. Primary attention is given to instructional factors that have been shown to affect literacy outcomes for adults with LD. These factors include the use of explicit instruction, instructional technology, and intensive tutoring in skills and strategies embedded in authentic contexts. PMID:22064951

    Ten adult patients with psychiatric disorders in the intensive care ward were examined. The length of stay varied from one week to four months and mechanical ventilation was necessary for all patients. Their experience of intensive care and their psychosensorial problems were as follows: temperospatial disorientation, perturbation of the sense of posture, hallucinations which could go as far as oneiric delirium, anguish and symptoms of depression. No psychotic syndrome, literraly speaking, was observed objectively. In the monthes that followed the stay under intensive care many patients presented important psychosomatic disorders. Organic factors are responsible for these complications, though the environment of the intensive care could induce a marked disafferentation. An effort by the attending staff, aimed at orientating or "reafferenting" these patients, could reduce these problems. PMID:30349

    Background The traditional method of teaching in Surgery is known as “See One, Do One, Teach One.” However, many have argued that this method is no longer applicable mainly because of concerns for patient safety. The purpose of this paper is to show that the basis of the traditional teaching method is still valid in surgical training if it is combined with various adult learning principles. Methods We reviewed literature regarding the history of the formation of the surgical residency program, adult learning principles, mentoring, and medical simulation. We provide examples for how these learning techniques can be incorporated into a surgical resident training program. Results The surgical residency program created by Dr. William Halsted remained virtually unchanged until recently with reductions in resident work hours and changes to a competency-based training system. Such changes have reduced the teaching time between attending physicians and residents. Learning principles such as “Experience, Observation, Thinking and Action” as well as deliberate practice can be used to train residents. Mentoring is also an important aspect in teaching surgical technique. We review the different types of simulators: standardized patients, virtual reality applications, and high-fidelity mannequin simulators and the advantages and disadvantages of using them. Conclusions The traditional teaching method of “see one, do one, teach one” in surgical residency programs is simple but still applicable. It needs to evolve with current changes in the medical system to adequately train surgical residents and also provide patients with safe, evidence-based care. PMID:23629100

    Summary Background Determining the optimal timing and progression of mobility exercise has the potential to affect functional recovery of critically ill adults. This study compared standard care with care delivered using a mobility protocol. We examined the effects of exercise on vital signs and inflammatory biomarkers and the effects of the nurse-initiated mobility protocol on outcomes. Methods Prospective, repeated measures study with a control (standard care) and intervention (protocol) period. Results 75 heterogeneous subjects admitted to a Medical or Surgical intensive care unit (ICU) were enrolled. In <5% of exercise periods, there was a concerning alteration in respiratory rate or peripheral oxygen saturation; no other adverse events occurred. Findings suggested the use of a protocol with one 20 minute episode of exercise daily for 2 or more days reduced ICU length of stay. Duration of exercise was linked to increased IL-10, suggesting brief episodes of low intensity exercise positively altered inflammatory dysregulation in this sample. Conclusion A growing body of evidence demonstrates that early, progressive exercise has significant benefits to intubated adults. These results should encourage clinicians to add mobility protocols to the care of ICU adults and lead to future studies to determine optimal “dosing” of exercise in ICU patients. PMID:22458998

    2013-02-01

    Discectomy for lumbar discal herniation is the most commonly performed spinal surgery. The basic principle of the various techniques is to relieve the nerve root compression induced by the herniation. Initially, the approach was a unilateral posterior 5-cm incision: the multifidus was detached from the vertebra, giving access through an interlaminar space in case of posterolateral herniation; an alternative paraspinal approach was used for extraforaminal herniation. Over the past 30 years, many technical improvements have decreased operative trauma by reducing incision size, thereby reducing postoperative pain and hospital stay and time off work, while improving clinical outcome. Magnification and illumination systems by microscope and endoscope have been introduced to enable minimally invasive techniques. Several comparative studies have analyzed the clinical results of these various techniques. Although the methodology of most of these studies is debatable, all approaches seem to provide clinical outcomes of similar quality. At all events, minimally invasive techniques reduce hospital stay. While technical proficiency is essential, the final result depends on strict compliance with a prerequisite for surgical indication: close correlation between clinical symptoms and radiological findings. It is essential to discuss the risk/benefit ratio and explain the pros and cons of the recommended technique to the patient. PMID:23352565

    Purpose: To evaluate the clinical outcome of patients with surgically refractory trigeminal neuralgia (TN) treated with rescue gamma knife radiosurgery (GKRS). Methods and Materials: Seventy-nine patients with typical TN received salvage GKRS between 1997 and 2002 at the Barrow Neurological Institute (BNI). All patients had recurrent pain following at least one prior surgical intervention. Prior surgical interventions included percutaneous destructive procedures, microvascular decompression (MVD), or GKRS. Thirty-one (39%) had undergone at least two prior procedures. The most common salvage dose was 80 Gy, although 40-50 Gy was typical in patients who had received prior radiosurgery. Pain outcome was assessed using the BNI Pain Intensity Score, and quality of life was assessed using the Brief Pain Inventory. Results: Median follow-up after salvage GKRS was 5.3 years. Actuarial analysis demonstrated that at 5 years, 20% of patients were pain-free and 50% had pain relief. Pain recurred in patients who had an initial response to GKRS at a median of 1.1 years. Twenty-eight (41%) required a subsequent surgical procedure for recurrence. A multivariate Cox proportional hazards model suggested that the strongest predictor of GKRS failure was a history of prior MVD (p=0.029). There were no instances of serious morbidity or mortality. Ten percent of patients developed worsening facial numbness and 8% described their numbness as 'very bothersome.' Conclusions: GKRS salvage for refractory TN is well tolerated and results in long-term pain relief in approximately half the patients treated. Clinicians may reconsider using GKRS to salvage patients who have failed prior MVD.

    Recent evidence suggests surgical quality may be demonstrated and evaluated using video capture during surgery. Operative video documentation may also aid in quality improvement initiatives. We discuss how operative video has the potential to help improve patient outcomes and increase professional accountability, patient safety, and surgical quality. PMID:27076573

    This review article provides an overview of talus fractures. Special attention is given to the clinical literature that evaluates the timing of surgical management for displaced talus fractures. Several series support delayed definitive fixation for talus fractures, suggesting displaced fractures do not necessitate emergent surgical fixation. PMID:27241385
