The authors describe the radiographic appearance of the left atrial catheter, a widely used postsurgical intracardiac device. Recognition of the characteristic appearance of this catheter should be of value in detection of potential complications, including line fracture with resultant retention and/or embolization, infection, prosthetic valve dysfunction, and even cardiac tamponade.

Although there is a growing body of literature reporting that pregnancies in women with polycystic ovary syndrome (PCOS) are associated with greater complications than those without PCOS, methodological differences across studies make these results difficult to consolidate. This narrative review outlines potential mechanisms involved in adverse pregnancy outcomes in PCOS and the nature of the complications. It covers limitations of current evidence and future research directions. Future research should include prospective studies with phenotypic stratification of PCOS and matching or consideration of specific PCOS manifestations and risk factors specific to each pregnancy complication. This review also emphasizes the importance of following a healthy lifestyle for women with PCOS and of individualized care according to overall risk factors for pregnancy complications. © 2018 John Wiley & Sons Ltd.

Parenteral nutrition: risks, complications, and management.

PubMed

Worthington, Patricia H; Gilbert, Karen A

2012-01-01

Parenteral nutrition is a life-saving modality, but one that also carries risks for potentially life-threatening complications. Comprehensive management of patients receiving parenteral nutrition includes careful selection of candidates, individualizing formulas to meet patients' unique needs, monitoring response to therapy, and implementing strategies designed to avoid complications. Measures to mitigate the risk of central line-associated bloodstream infections are particularly important. As with all complex therapies, a collaborative, multidisciplinary approach promotes optimal outcomes.

Lumen apposing metal stents for pancreatic fluid collections: Recognition and management of complications.

PubMed

DeSimone, Michael L; Asombang, Akwi W; Berzin, Tyler M

2017-09-16

For patients recovering from acute pancreatitis, the development of a pancreatic fluid collection (PFC) predicts a more complex course of recovery, and introduces difficult management decisions with regard to when, whether, and how the collection should be drained. Most PFCs resolve spontaneously and drainage is indicated only in pseudocysts and walled-off pancreatic necrosis when the collections are causing symptoms and/or local complications such as biliary obstruction. Historical approaches to PFC drainage have included surgical (open or laparoscopic cystgastrostomy or pancreatic debridement), and the placement of percutaneous drains. Endoscopic drainage techniques have emerged in the last several years as the preferred approach for most patients, when local expertise is available. Lumen-apposing metal stents (LAMS) have recently been developed as a tool to facilitate potentially safer and easier endoscopic drainage of pancreatic fluid collections, and less commonly, for other indications, such as gallbladder drainage. Physicians considering LAMS placement must be aware of the complications most commonly associated with LAMS including bleeding, migration, buried stent, stent occlusion, and perforation. Because of the patient complexity associated with severe pancreatitis, management of pancreatic fluid collections can be a complex and multidisciplinary endeavor. Successful and safe use of LAMS for patients with pancreatic fluid collections requires that the endoscopist have a full understanding of the potential complications of LAMS techniques, including how to recognize and manage expected complications.

D'hondt, Sanne; Van Damme, Tim; Malfait, Fransiska

2018-01-01

Purpose Within the spectrum of the Ehlers-Danlos syndromes (EDS), vascular complications are usually associated with the vascular subtype of EDS. Vascular complications are also observed in other EDS subtypes, but the reports are anecdotal and the information is dispersed. To better document the nature of vascular complications among “nonvascular” EDS subtypes, we performed a systematic review. Methods We queried three databases for English-language studies from inception until May 2017, documenting both phenotypes and genotypes of patients with nonvascular EDS subtypes. The outcome included the number and nature of vascular complications. Results A total of 112 papers were included and data were collected from 467 patients, of whom 77 presented with a vascular phenotype. Severe complications included mainly hematomas (53%), frequently reported in musculocontractural and classical-like EDS; intracranial hemorrhages (18%), with a high risk in dermatosparaxis EDS; and arterial dissections (16%), frequently reported in kyphoscoliotic and classical EDS. Other, more minor, vascular complications were reported in cardiac-valvular, arthrochalasia, spondylodysplastic, and periodontal EDS. Conclusion Potentially life-threatening vascular complications are a rare but important finding in several nonvascular EDS subtypes, highlighting a need for more systematic documentation. This review will help familiarize clinicians with the spectrum of vascular complications in EDS and guide follow-up and management. PMID:28981071

Potential costs of breast augmentation mammaplasty.

PubMed

Schmitt, William P; Eichhorn, Mitchell G; Ford, Ronald D

2016-01-01

Augmentation mammaplasty is one of the most common surgical procedures performed by plastic surgeons. The aim of this study was to estimate the cost of the initial procedure and its subsequent complications, as well as project the cost of Food and Drug Administration (FDA)-recommended surveillance imaging. The potential costs to the individual patient and society were calculated. Local plastic surgeons provided billing data for the initial primary silicone augmentation and reoperative procedures. Complication rates used for the cost analysis were obtained from the Allergen Core study on silicone implants. Imaging surveillance costs were considered in the estimations. The average baseline initial cost of silicone augmentation mammaplasty was calculated at $6335. The average total cost of primary breast augmentation over the first decade for an individual patient, including complications requiring reoperation and other ancillary costs, was calculated at $8226. Each decade thereafter cost an additional $1891. Costs may exceed $15,000 over an averaged lifetime, and the recommended implant surveillance could cost an additional $33,750. The potential cost of a breast augmentation, which includes the costs of complications and imaging, is significantly higher than the initial cost of the procedure.

Ocular complications associated with local anesthesia administration in dentistry.

PubMed

Boynes, Sean G; Echeverria, Zydnia; Abdulwahab, Mohammad

2010-10-01

The most widely used method for controlling pain during dental procedures is the intraoral administration of local anesthetics in close proximity to a specific nerve or fiber to obtund nerve conduction. The most commonly anesthetized nerves in dentistry are branches or nerve trunks associated with the maxillary and mandibular divisions of the trigeminal nerve (cranial nerve V). However, other nerves may be inadvertently affected by intraoral local anesthesia injections, resulting in anesthetic complications of structures far from the oral cavity. Practitioners should be aware of potential ocular complications following intraoral injections in dentistry. These complications include oculomotor paralysis and vision loss. The knowledge of these conditions and their potential cause should alert the dentist to the importance of appropriate injection techniques and an understanding of management protocol.

Despite improvement in surgical technique and medical management of liver transplant recipients, biliary complications remain a frequent cause of posttransplant morbidity and graft loss. Biliary complications require potentially expensive interventions including radiologic procedures and surgical revisions. A national data set linking transplant registry and Medicare claims data for 12,803 liver transplant recipients was developed to capture information on complications, treatments, and associated direct medical costs up to 3 years after transplantation. Biliary complications were more common in recipients of donation after cardiac death compared to donation after brain death allografts (23% vs. 19% P<0.001). Among donation after brain death recipients, biliary complications were associated with $54,699 (95% confidence interval [CI], $49,102 to $60,295) of incremental spending in the first year after transplantation and $7,327 in years 2 and 3 (95% CI, $4,419-$10,236). Biliary complications in donation after cardiac death recipients independently increased spending by $94,093 (95% CI, $64,643-$124,542) in the first year and $12,012 (95% CI, $-1,991 to $26,016) in years 2 and 3. This national study of biliary complications demonstrates the significant economic impact of this common perioperative complication and suggests a potential target for quality of care improvements.

Transverse rectus abdominus myocutaneous (TRAM) flap is one of the commonly used techniques for breast reconstruction. Postoperative pain relief is of paramount importance following TRAM flap breast reconstruction to avoid potentially preventable complications like chest infection. Several methods of pain control are available, including intrapleural anesthesia. Here we report a case of a patient who developed ventricular standstill as a complication of intrapleural bupivacaine.

birth is a natural and for many, life enhancing phenomenon. In rare circumstances however birth can be accompanied with complications that may place the mother and infant at risk of severe trauma or death. Witnessing birth complications or obstetric emergencies can be distressing and potentially traumatic for the father. the aim of this paper is to report on the findings of a meta-ethnographic synthesis of father's experiences of complicated births that are potentially traumatic. databases searched included CINAHL, Scopus, PubMed and PsycINFO with Full Text. The search was conducted in February and March 2013 and revised in February 2015 for any new papers, and the search was limited to papers published in English, full text and peer-reviewed journals published between January 2000 to December 2013. studies were included if they focused on fathers/men's experiences of witnessing a birth with complications including a caesarean section or an adverse obstetric event. Studies included needed to use qualitative or mixed methods research designs with a substantial qualitative component. ANALYTIC STRATEGY: a meta-ethnographic approach was used using methods of reciprocal translation guided by the work of Noblit and Hare (1988) on meta-ethnographic techniques. Quality appraisal was undertaken using the Critical Appraisal Skills Programme (CASP) tool. eight qualitative studies with a total of 100 participants were included in the final sample. The men ranged in age from 19 to 50 years. Four major themes were identified: 'the unfolding crisis', 'stripped of my role: powerless and helpless', 'craving information' and 'scarring the relationship'. Participants described the fear and anxiety they felt as well as having a sense of worthlessness and inadequacy. Men did not receive sufficient information about the unfolding events and subsequently this birth experience impacted on some men's interactions and relationships with their partners. witnessing a complicated or unexpected adverse birth experience can be distressing for men and some may report symptoms of birth trauma. Being informed by and receiving support from midwives and other health professionals appears to help mitigate the negative impact of birth complications. Effective support may help address men's confusion about their role, however genuinely including men as recipients of care or service in pregnancy, labour and birth raises important questions about whether the father is also a recipient of maternity care and if the transition to fatherhood is itself becoming a medical event?

2015-03-01

As surgical complications tend to occur more frequently in the beginning stages of a surgeon's career, knowledge of perioperative complications is important to perform a safe procedure, especially if the surgeon is a novice. We sought to identify and describe perioperative complications and their management in connection with minimally invasive transforaminal lumbar interbody fusion (TLIF). We performed a retrospective chart review of our first 124 patients who underwent minimally invasive TLIF. The primary outcome measure was adverse events during the perioperative period, including neurovascular injury, implant-related complications, and wound infection. Pseudarthroses and adjacent segment pathologies were not included in this review. Adverse events that were not specifically related to spinal surgery and did not affect recovery were also excluded. Perioperative complications occurred in 9% of patients (11/124); including three cases of temporary postoperative neuralgia, two deep wound infections, two pedicle screw misplacements, two cage migrations, one dural tear, and one grafted bone extrusion. No neurologic deficits were reported. Eight complications occurred in the first one-third of the series and only 3 complications occurred in the last two-thirds of the series. Additional surgeries were performed in 6% of patients (7/124); including four reoperations (two for cage migrations, one for a misplaced screw, and one for an extruded graft bone fragment) and three hardware removals (one for a misplaced screw and two for infected cages). We found perioperative complications occurred more often in the early period of a surgeon's experience with minimally invasive TLIF. Implant-related complications were common and successfully managed by additional surgeries in this series. We suggest greater caution should be exercised to avoid the potential complications, especially when surgeon is a novice to this procedure.

A thorough account is given of the complications of embolization techniques in nonneurovascular areas, including hepatic infarction, renal and splenic abscess formation. Infarction of the urinary bladder, gallbladder, stomach, and bowel are discussed. Suggestions are offered to prevent complications from embolization where possible. Specific agents for embolization are detailed and their relative merits are compared; ethyl alcohol has recently gained popularity for treating esophageal varices and infarcting renal tumors. Care is advocated when using alcohol in the renal arteries; employing this agent is currently contraindicated in the celiac and mesenteric arteries. Coils and balloon systems are also described along with their potential complications.

Long term hyperglycemia leads to development of complications associated with diabetes. Diabetic complications are now a global health problem without effective therapeutic approach. Hyperglycemia and oxidative stress are important components for the development of diabetic complications. Over the past few decades, herbal medicines have attracted much attention as potential therapeutic agents in the prevention and treatment of diabetic complications due to their multiple targets and less toxic side effects. This review aims to assess the current available knowledge of medicinal herbs for attenuation and management of diabetic complications and their underlying mechanisms. Bibliographic investigation was carried out by scrutinizing classical text books and peer reviewed papers, consulting worldwide accepted scientific databases (SCOPUS, PUBMED, SCIELO, NISCAIR, Google Scholar) to retrieve available published literature. The inclusion criteria for the selection of plants were based upon all medicinal herbs and their active compounds with attributed potentials in relieving diabetic complications. Moreover, plants which have potential effect in ameliorating oxidative stress in diabetic animals have been included. Overall, 238 articles were reviewed for plant literature and out of the reviewed literature, 127 articles were selected for the study. Various medicinal plants/plant extracts containing flavonoids, alkaloids, phenolic compounds, terpenoids, saponins and phytosterol type chemical constituents were found to be effective in the management of diabetic complications. This effect might be attributed to amelioration of persistent hyperglycemia, oxidative stress and modulation of various metabolic pathways involved in the pathogenesis of diabetic complications. Screening chemical candidate from herbal medicine might be a promising approach for new drug discovery to treat the diabetic complications. There is still a dire need to explore the mechanism of action of various plant extracts and their toxicity profile and to determine their role in therapy of diabetic complications. Moreover, a perfect rodent model which completely mimics human diabetic complications should be developed. © 2013 Elsevier Ireland Ltd. All rights reserved.

Increasing popularity of strong magnets as toys has led to their ingestion by children, putting them at risk of potentially harmful gastrointestinal tract injuries. To heighten physician awareness of the potential complications of magnetic foreign body ingestion, and to provide an updated algorithm for management of a patient who is suspected to have ingested magnets. A retrospective review of magnet ingestions treated over a two-year period at our institutions in the Southern California Permanente Medical Group. Data including patient demographics, clinical information, radiologic images, and surgical records were used to propose a management strategy. Five patients, aged 15 months to 18 years, presented with abdominal symptoms after magnet ingestion. Four of the 5 patients suffered serious complications, including bowel necrosis, perforation, fistula formation, and obstruction. All patients were successfully treated with laparoscopic-assisted exploration with or without endoscopy. Total days in the hospital averaged 5.2 days (range = 3 to 9 days). Average time to discharge following surgery was 4 days (range = 2 to 7 days). Ex vivo experimentation with toy magnetic beads were performed to reveal characteristics of the magnetic toys. Physicians should have a heightened sense of caution when treating a patient in whom magnetic foreign body ingestion is suspected, because of the potential gastrointestinal complications. An updated management strategy is proposed that both prevents delays in surgical care and avoids unnecessary surgical exploration.

There is a paucity of experience in the published literature documenting complications of powered surgical instruments in laryngologic surgery. Our objective was to ascertain the nature of these complications from expert opinion and review of the literature, and to recommend strategies to decrease major complications. Review of the literature and an e-mail survey. A literature review of microdebrider complications in laryngologic surgery was conducted using PubMed and Ovid (1985 to 2013), along with an analysis of a confidential e-mail survey of various surgeons in selected high-volume laryngologic centers. Powered instrumentation is frequently used in the operating room for larynx and airway surgery. The microdebrider can improve efficiency, lower costs, and shorten operative times. However, use of the microdebrider has the potential for serious complications in the larynx and airway. Great care must be taken when utilizing the microdebrider in laryngologic surgery. Significant complications including major vocal fold scar, airway compromise, severe hemorrhage, and unintentional tissue loss have occurred. The microdebrider is a popular and valuable tool for the otolaryngologist. A thorough knowledge of the instrument and its potential complications will improve surgical outcomes and may prevent complications. Awareness of the risks and surgeon experience with use of the microdebrider will allow the surgeon to successfully utilize this device in a safe and effective manner. 5. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

Surgical complications contribute substantially to costs. Most important, surgical complications contribute to morbidity and mortality, and some may be preventable. This study estimates costs of specific surgical complications for patients undergoing general surgery in VA hospitals using merged data from the VA Surgical Quality Improvement Program and VA Decision Support System. Costs associated with 19 potentially preventable complications within 6 broader categories were estimated using generalized, linear mixed regression models to control for patient-level determinants of costs (eg, type of operation, demographics, comorbidity, severity) and hospital-level variation in costs. Costs included costs of the index hospitalization and subsequent 30-day readmissions. In 14,639 patients undergoing general surgical procedures from 10/2005 through 9/2006, 20% of patients developed postoperative surgical complications. The presence of any complication significantly increased unadjusted costs nearly 3-fold ($61,083 vs $22,000), with the largest cost differential attributed to respiratory complications. Patients who developed complications had several markers for greater preoperative severity, including increased age and a lesser presurgery functional health status. After controlling for differences in patient severity, costs for patients with any complication were 1.89 times greater compared to costs for patients with no complications (P < .0001). Within major complication categories, adjusted costs were significantly greater for patients with respiratory, cardiac, central nervous system, urinary, wound, or other complications. Surgical complications contribute markedly to costs of inpatient operations. Investment in quality improvement that decreases the incidence of surgical complications could decrease costs.

Complication profiles of medial thighplasty in the massive weight loss population are not well described. The authors present their experience with these procedures in the massive weight loss population. Thighplasty patients from 2003 to 2012 were assessed. Variables included age, sex, body mass index, method of weight loss, comorbidities, and smoking status. Outcomes included seroma, dehiscence, infection, hematoma, edema, and revision. Statistical analysis was performed as appropriate. One hundred six subjects (90 women and 16 men) underwent thighplasty. Fourteen patients underwent horizontal thighplasty, with a complication rate of 43 percent; 24 underwent short-scar thighplasty, with a complication rate of 67 percent; and 68 underwent full-length vertical thighplasty, with a complication rate of 74 percent. Seventy-two subjects (68 percent) had at least one complication. Complications included dehiscence (51 percent), seroma (25 percent), infection (16 percent), and hematoma (6 percent). Overall, 25 patients (23 percent) developed edema, which did not resolve in two patients by 12 months. Hypertension was significantly associated with postoperative seroma (p = 0.02). Age (p = 0.01), hypothyroidism (p = 0.01), and liposuction outside the area of resection (p = 0.025) were associated with postoperative infections. A full-length vertical incision was associated with increased lower extremity edema (p = 0.007). Medial thighplasty has a high rate of minor wound healing problems. Full-length vertical thighplasty is associated with prolonged edema. Concomitant liposuction may also increase complications. Patients should be counseled appropriately about the potential for minor wound healing problems. Therapeutic, III.

Over the last 50 years, parenteral nutrition has been recognised as an invaluable and potentially lifesaving tool in the physician's arsenal in the management of patients with intestinal failure or inaccessibility; however, it may also be associated with a number of potentially life-threatening complications. A recent NCEPOD report (2010) identified a number of inadequacies in the overall provision and management of parenteral nutrition and recommendations were made with the aim of improving clinical practice in the future. This paper focuses on the practical aspects relating to parenteral nutrition for adults, including important concepts, such as patient selection, as well as general management. We also explore the various pitfalls and potential complications and how these may be minimised.

Magnetic resonance imaging of breast implants.

Silicone breast implants have significantly evolved since their introduction half a century ago, yet implant rupture remains a common and expected complication, especially in patients with earlier-generation implants. Magnetic resonance imaging is the primary modality for assessing the integrity of silicone implants and has excellent sensitivity and specificity, and the Food and Drug Administration currently recommends periodic magnetic resonance imaging screening for silent silicone breast implant rupture. Familiarity with the types of silicone implants and potential complications is essential for the radiologist. Signs of intracapsular rupture include the noose, droplet, subcapsular line, and linguine signs. Signs of extracapsular rupture include herniation of silicone with a capsular defect and extruded silicone material. Specific sequences including water and silicone suppression are essential for distinguishing rupture from other pathologies and artifacts. Magnetic resonance imaging provides valuable information about the integrity of silicone implants and associated complications.

Hematopoietic stem cell transplantation (HSCT) is widely used as a potentially curative treatment for patients with various hematological malignancies, bone marrow failure syndromes, and congenital immune deficiencies. The prevalence of oral complications in both autologous and allogeneic HSCT recipients remains high, despite advances in transplant medicine and in supportive care. Frequently encountered oral complications include mucositis, infections, oral dryness, taste changes, and graft versus host disease in allogeneic HSCT. Oral complications are associated with substantial morbidity and in some cases with increased mortality and may significantly affect quality of life, even many years after HSCT. Inflammatory processes are key in the pathobiology of most oral complications in HSCT recipients. This review article will discuss frequently encountered oral complications associated with HSCT focusing on the inflammatory pathways and inflammatory mediators involved in their pathogenesis.

Patients with CKD are at increased risk of potentially preventable hospital acquired complications (HACs). Understanding the economic consequences of preventable HACs, may define the scope and investment of initiatives aimed at prevention. Adult patients hospitalized from April, 2003 to March, 2008 in Alberta, Canada comprised the study cohort. Healthcare costs were determined and categorized into 'index hospitalization' including hospital cost and in-hospital physician claims, and 'post discharge' including ambulatory care cost, physician claims, and readmission costs from discharge to 90 days. Multivariable regression was used to estimate the incremental healthcare costs associated with potentially preventable HACs. In fully adjusted models, the median incremental index hospitalization cost was CAN-$6169 (95% CI; 6003-6336) in CKD patients with ≥1 potentially preventable HACs, compared with those without. Post-discharge incremental costs were 1471(95% CI; 844-2099) in those patients with CKD who developed potentially preventable HACs within 90 days after discharge compared with patients without potentially preventable HACs. Additionally, the incremental costs associated with ≥1 potentially preventable HACs within 90 days from admission in patients with CKD were $7522 (95% CI; 7219-7824). A graded relation of the incremental costs was noted with the increasing number of complications. In patients without CKD but with ≥1 preventable HACs incremental costs within 90 days from hospital admission was $6688 (95% CI: 6612-6723). Potentially preventable HACs are associated with substantial increases in healthcare costs in people with CKD. Investment in implementing targeted strategies to reduce HACs may have a significant benefit for patient and health system outcomes.

Totally implantable venous access port systems are widely used in oncology, with frequent complications that sometimes necessitate device removal. The aim of this study is to investigate the impact of the time interval between port placement and initiation of chemotherapy and the neutropenia-inducing potential of the chemotherapy administered upon complication-related port removal. Between January 2010 and December 2013, 4045 consecutive patients were included in this observational, single-center prospective study. The chemotherapy regimens were classified as having a low (<10%), intermediate (10-20%), or high (>20%) risk for inducing neutropenia. The overall removal rate due to complications was 7.2%. Among them, port-related infection (2.5%) and port expulsion (1%) were the most frequent. The interval between port insertion and its first use was shown to be a predictive factor for complication-related removal rates. A cut-off of 6 days was statistically significant (p = 0.008), as the removal rate for complications was 9.4% when this interval was 0-5 days and 5.7% when it was ≥6 days. Another factor associated with port complication rate was the neutropenia-inducing potential of the chemotherapy regimens used, with removal for complications involved in 5.5% of low-risk regimens versus 9.4% for the intermediate- and high-risk regimens (p = 0.003). An interval of 6 days between placement and first use of the port reduces the removal rate from complications. The intermediate- and high-risk for neutropenia chemotherapy regimens are related to higher port removal rates from complications than low-risk regimens.

The Agency for Healthcare Research and Quality in the United States recommends the use of ultrasound (US) for central venous access to improve patient outcomes. However, in a recent publication, US is still underutilized for axillary vein access during pacemaker implantation. We sought to describe a technique for US-guided axillary vein access during pacemaker implantation and to report complication rates and success rate. Retrospective data collection included success rate and complications on all pacemaker implants by one operator since implementing the systematic use of US at our institution, from November 2012 to January 2015. For the last 59 cases, data were collected prospectively to include time of venous access and number of attempts. A total of 403 consecutive patients were included in the analysis. Two leads were implanted in 255 cases and one lead was implanted in 148 cases. The rate of successful US-guided access was 99.25%. There were no access-related complications. The average number of venipuncture attempts was 1.18 per patient. The average time to obtain venous access was 2.24 minutes including the time to apply the sterile US sleeve. The described technique has the potential to improve the success rate of axillary vein access and minimize complications during pacemaker implantation. ©2016 Wiley Periodicals, Inc.

Introduction: Bone grafts are commonly used in oral and maxillofacial surgery, helping to restore missing bone structure and provide osseous support. In spite of their reported success, complications can and do arise. Examples include loosening and resorption of the graft, infection, and complete loss of the graft. These complications can potentially lead to larger defects, necessitating additional procedures to correct the problem. This not only causes great discomfort to the patient, but also drains considerable time and resources away from the clinician. Thus, improvements on identifying ways to identify and prevent these complications are constantly being sought. We have performed a literature review and identified several areas in the field of optics that could potentially help solve our problem. Optical Techniques: Raman spectroscopy has been shown to provide a transcutaneous measurement of bone mineral and matrix Raman bands. This could potentially provide surgeons with the ability to more accurately assess bone graft osseointegration. In-vivo near-infrared optical imaging could potentially provide accurate diagnosis of pathologic lesions such as osteosarcoma. Contrast-enhanced ultrasound could be used to detect vascular disturbances and other information related to the transplantation of osseous components. Conclusion: Bone graft complications can be one of the most devastating consequences of osseous surgery. As surgeons, we are constantly searching for ways to identify them earlier and prevent them. We hope that by presenting areas that could be used, we can gain a better insight to ways in which both fields can benefit.

Multicenter retrospective study of 54 children. To describe the complication rate of the French vertical expandable prosthetic titanium rib (VEPTR) series involving patients treated between August 2005 and January 2012. Congenital chest wall and spine deformities in children are complex entities. Most of the affected patients have severe scoliosis often associated with a thoracic deformity. Orthopedic treatment is generally ineffective, and surgical treatment is very challenging. These patients are good candidates for VEPTR expansion thoracoplasty. The aim of this study was to evaluate the potential complications of VEPTR surgery. Of the 58 case files, 54 were available for analysis. The series involved 33 girls and 21 boys with a mean age of 7 years (range, 20 mo-14 yr and 2 mo) at primary VEPTR surgery. During the follow-up period, several complications occurred. Mean follow-up was 22.5 months (range, 6-64 mo). In total, 184 procedures were performed, including 56 VEPTR implantations, 98 expansions, and 30 nonscheduled procedures for different types of complications: mechanical complications (i.e., fracture, device migration), device-related and infectious complications, neurological disorders, spine statics disturbances. Altogether, there were 74 complications in 54 patients: a complication rate of 137% per patient and 40% per surgery. Comparison of the complications in this series with those reported in the literature led the authors to suggest solutions that should help decrease their incidence. The complication rate is consistent with that reported in the literature. Correct determination of the levels to be instrumented, preoperative improvement of nutritional status, and better evaluation of the preoperative and postoperative respiratory function are important factors in minimizing the potential complications of a technique that is used in weak patients with complex deformities.

A clinical retrospective study. To analyze the complications and relevant management of the correction procedure for focal kyphosis. The treatment of focal kyphosis is a difficult problem in spine surgery. The potential complications of surgery should be considered cautiously and managed positively. Eighty-one patients with focal kyphosis were treated by posterior osteotomy and correction. The etiology was posttraumatic in 31 cases, healed tuberculosis in 31 cases, congenital in 17 cases, and iatrogenic in 2 cases. The surgical procedures were pedicle subtraction osteotomy in 19 cases, posterior osteotomy with anterior opening-posterior closing correction in 23 cases, and posterior vertebral column resection with dual axial rotation correction in 39 cases. The intraoperative and postoperative complications were summarized, and the corresponding management was described in detail. The average follow-up time was 31 months. Among patients who underwent pedicle subtraction osteotomy, the intraoperative and postoperative complications included 3 cases of dural tear and 1 case of wound infection. For posterior osteotomy with anterior opening-posterior closing correction, the complications included 4 cases of dural tear, 1 case of wound infection, and 1 case of instrumentation loosening and recurrence of kyphosis . For posterior vertebral column resection with dual axial rotation correction, the complications included 3 cases of dural tear, 5 cases of nerve root injury, 1 case of titanium mesh loosening, 1 case of osteotomy segment migration, 2 cases of transient neurological compromise, and 1 case of instrumentation loosening and kyphosis recurrence. All the complications were treated positively and pertinently. During the posterior osteotomy and correction of focal kyphosis, the risk of surgery increases along with the more severe deformity and the more complicated surgical procedure. However, most complications do not significantly affect the outcome if treated appropriately.

Three-dimensional datasets acquired using computed tomography and magnetic resonance imaging are ideally suited for characterization of the aortic root. These modalities offer different advantages and limitations, which must be weighed according to the clinical context. This article provides an overview of current aortic root imaging, highlighting normal anatomy, pathologic conditions, imaging techniques, measurement thresholds, relevant surgical procedures, postoperative complications and potential imaging pitfalls. Patients with a range of clinical conditions are predisposed to aortic root disease, including Marfan syndrome, bicuspid aortic valve, vascular Ehlers-Danlos syndrome, and Loeys-Dietz syndrome. Various surgical techniques may be used to repair the aortic root, including placement of a composite valve graft, such as the Bentall and Cabrol procedures; placement of an aortic root graft with preservation of the native valve, such as the Yacoub and David techniques; and implantation of a biologic graft, such as a homograft, autograft, or xenograft. Potential imaging pitfalls in the postoperative period include mimickers of pathologic processes such as felt pledgets, graft folds, and nonabsorbable hemostatic agents. Postoperative complications that may be encountered include pseudoaneurysms, infection, and dehiscence. Radiologists should be familiar with normal aortic root anatomy, surgical procedures, and postoperative complications, to accurately interpret pre- and postoperative imaging performed for evaluation of the aortic root.

Context: Increasing popularity of strong magnets as toys has led to their ingestion by children, putting them at risk of potentially harmful gastrointestinal tract injuries. Objectives: To heighten physician awareness of the potential complications of magnetic foreign body ingestion, and to provide an updated algorithm for management of a patient who is suspected to have ingested magnets. Design: A retrospective review of magnet ingestions treated over a two-year period at our institutions in the Southern California Permanente Medical Group. Data including patient demographics, clinical information, radiologic images, and surgical records were used to propose a management strategy. Results: Five patients, aged 15 months to 18 years, presented with abdominal symptoms after magnet ingestion. Four of the 5 patients suffered serious complications, including bowel necrosis, perforation, fistula formation, and obstruction. All patients were successfully treated with laparoscopic-assisted exploration with or without endoscopy. Total days in the hospital averaged 5.2 days (range = 3 to 9 days). Average time to discharge following surgery was 4 days (range = 2 to 7 days). Ex vivo experimentation with toy magnetic beads were performed to reveal characteristics of the magnetic toys. Conclusions: Physicians should have a heightened sense of caution when treating a patient in whom magnetic foreign body ingestion is suspected, because of the potential gastrointestinal complications. An updated management strategy is proposed that both prevents delays in surgical care and avoids unnecessary surgical exploration. PMID:23596362

Complications of circumcision in male neonates, infants and children: a systematic review

PubMed Central

2010-01-01

Background Approximately one in three men are circumcised globally, but there are relatively few data on the safety of the procedure. The aim of this paper is to summarize the literature on frequency of adverse events following pediatric circumcision, with a focus on developing countries. Methods PubMed and other databasess were searched with keywords and MeSH terms including infant/newborn/pediatric/child, circumcision, complications and adverse events. Searches included all available years and were conducted on November 6th 2007 and updated on February 14th 2009. Additional searches of the Arabic literature included searches of relevant databases and University libraries for research theses on male circumcision. Studies were included if they contained data to estimate frequency of adverse events following neonatal, infant and child circumcision. There was no language restriction. A total of 1349 published papers were identified, of which 52 studies from 21 countries met the inclusion criteria. The Arabic literature searches identified 46 potentially relevant papers, of which six were included. Results Sixteen prospective studies evaluated complications following neonatal and infant circumcision. Most studies reported no severe adverse events (SAE), but two studies reported SAE frequency of 2%. The median frequency of any complication was 1.5% (range 0-16%). Child circumcision by medical providers tended to be associated with more complications (median frequency 6%; range 2-14%) than for neonates and infants. Traditional circumcision as a rite of passage is associated with substantially greater risks, more severe complications than medical circumcision or traditional circumcision among neonates. Conclusions Studies report few severe complications following circumcision. However, mild or moderate complications are seen, especially when circumcision is undertaken at older ages, by inexperienced providers or in non-sterile conditions. Pediatric circumcision will continue to be practiced for cultural, medical and as a long-term HIV/STI prevention strategy. Risk-reduction strategies including improved training of providers, and provision of appropriate sterile equipment, are urgently needed. PMID:20158883

Otitis media (OM) is considered a potentially severe disease due to the risk of complications. To establish the annual incidence of intratemporal complications (ITC) resulting from OM and to prospectively assess patients for epidemiological and clinical factors. This prospective cohort study included patients admitted during one year at a university hospital diagnosed with intratemporal complications of OM. Patients were analyzed for age, gender, type of intratemporal complication, treatment, and clinical outcome. The overall incidence of complications and the specific incidence rates of each type of complication were determined. 1,816 patients were diagnosed with OM; 592 (33%) had chronic OM; 1224 (67%) had acute OM. Fifteen patients were diagnosed with OM ITC, adding up to an annual incidence of 0.8%. Nineteen diagnoses of ITC were made in 15 patients. Seven (36.8%) patients were diagnosed with labyrinthine fistula, five (26.3%) with mastoiditis, four (21.1%) with peripheral facial palsy, and three (15.8%) with labyrinthitis. The incidence of intratemporal complications remains significant when compared to the rates seen in developed countries. Chronic cholesteatomatous otitis media is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.

Postoperative pulmonary complications are associated with increased morbidity, length of hospital stay, and mortality after major surgery. Intraoperative lung-protective mechanical ventilation has the potential to reduce the incidence of postoperative pulmonary complications. This review discusses the relevant literature on definition and methods to predict the occurrence of postoperative pulmonary complication, the pathophysiology of ventilator-induced lung injury with emphasis on the noninjured lung, and protective ventilation strategies, including the respective roles of tidal volumes, positive end-expiratory pressure, and recruitment maneuvers. The authors propose an algorithm for protective intraoperative mechanical ventilation based on evidence from recent randomized controlled trials.

The use of dermal fillers in minimally invasive facial aesthetic procedures has become increasingly popular of late, yet as the indications and the number of procedures performed increase, the number of complications is also likely to increase. Paying special attention to specific patient characteristics and to the technique used can do much to avoid these complications. Indeed, a well-trained physician can also minimize the impact of such problems when they do occur. A multidisciplinary group of experts in aesthetic treatments reviewed the main factors associated with the complications that arise when using dermal fillers. A search of English, French and Spanish language articles in PubMed was performed using the terms "complications" OR "soft filler complications" OR "injectable complications" AND "dermal fillers". An initial document was drafted that reflected the complications identified and recommendations as to how they should be handled. This document was then reviewed and modified by the expert panel, until a final text was agreed upon and validated. The panel addressed consensus recommendations about the preparation, the procedure and the post-procedural care. The panel considered it crucial to obtain an accurate medical history to prevent potential complications. An additional clinical assessment, including standardized photography, is also crucial to evaluate the outcomes and prevent potential complications. Furthermore, the state of the operating theatre, the patient's health status and the preparation of the skin are critical to prevent superficial soft tissue infections. Finally, selecting the appropriate technique, based on the physician's experience, as well as the characteristics of the patient and filler, helps to ensure successful outcomes and limits the complications. This consensus document provides key elements to help clinicians who are starting to use dermal fillers to employ standard procedures and to understand how best to prevent potential complications of the treatment.

Metabolic memory and chronic diabetes complications: potential role for epigenetic mechanisms.

PubMed

Intine, Robert V; Sarras, Michael P

2012-10-01

Recent estimates indicate that diabetes mellitus currently affects more than 10 % of the world's population. Evidence from both the laboratory and large scale clinical trials has revealed that prolonged hyperglycemia induces chronic complications which persist and progress unimpeded even when glycemic control is pharmaceutically achieved via the phenomenon of metabolic memory. The epigenome is comprised of all chromatin modifications including post translational histone modification, expression control via miRNAs and the methylation of cytosine within DNA. Modifications of these epigenetic marks not only allow cells and organisms to quickly respond to changing environmental stimuli but also confer the ability of the cell to "memorize" these encounters. As such, these processes have gained much attention as potential molecular mechanisms underlying metabolic memory and chronic diabetic complications. Here we present a review of the very recent literature published pertaining to this subject.

BACKGROUND Limited information is available on preoperative status and risks for complications for older patients having surgery for hip fracture. Our objective was to identify potentially modifiable clinical findings that should be considered in decisions about the timing of surgery. METHODS We conducted a prospective cohort study with data obtained from medical records and through structured interviews with patients. A total of 571 adults with hip fracture who were admitted to 4 metropolitan hospitals were included. RESULTS Multiple logistic regression was used to identify risk factors (including 11 categories of physical and laboratory findings, classified as mild and severe abnormalities) for in-hospital complications. The presence of more than 1 (odds ratiol [OR] 9.7, 95% confidence interval [CI] 2.8 to 33.0) major abnormality before surgery or the presence of major abnormalities on admission that were not corrected prior to surgery (OR 2.8, 95% CI 1.2 to 6.4) was independently associated with the development of postoperative complications. We also found that minor abnormalities, while warranting correction, did not increase risk (OR 0.70, 95% CI 0.28 to 1.73). CONCLUSIONS In this study of older adults undergoing urgent surgery, potentially reversible abnormalities in laboratory and physical examination occurred frequently and significantly increased the risk of postoperative complications. Major clinical abnormalities should be corrected prior to surgery, but patients with minor abnormalities may proceed to surgery with attention to these medical problems perioperatively.

Extremity injuries necessitating splinting or casting are commonly seen in the emergency department (ED) setting. Subsequently, it is not uncommon for patients to present to the ED with complaints related to an extremity cast or splint. To present a literature-based approach to the identification and initial management of patients with possible infectious cast/splint complications in the ED setting. We present two cases of serious infectious complications arising from extremity cast/splint placement seen in a single pediatric ED: a case of toxic shock syndrome in an 8-year-old child, and a case of necrotizing fasciitis resulting in upper extremity amputation in a 3-year-old child. A wide spectrum of potential extremity cast/splint infectious complications may be seen, which include limb- or life-threatening infections such as toxic shock syndrome and necrotizing fasciitis. Simply considering these diagnoses, and removing the cast or splint to carefully inspect the affected extremity, are potential keys to early identification and optimal outcome of cast/splint complications. It is also prudent to maintain particular vigilance when treating a patient with a water-exposed cast, which may lead to moist padding, skin breakdown, and potential infection. In patients with suspected serious infections, aggressive fluid management and antibiotic therapy should be initiated and appropriate surgical consultation obtained without delay.

Varicella Pneumonia Complicating Pregnancy: A Report of Seven Cases

PubMed Central

Schutte, Teresa J.; Rogers, Louise C.

1996-01-01

Background: Pneumonia is the most common complication of varicella-zoster infection in adults and has potentially devastating effects when complicating pregnancy. Due to the significant morbidity and mortality associated with this complication during pregnancy and the small number of reported cases in the literature, we present this report to help educate physicians who care for pregnant women. Cases: Seven patients are presented in this report. These patients presented at various stages in pregnancy, from 17 to 31 weeks of gestation. Three of the patients had unremarkable hospital courses. Three of the patients had hospital stays over 21 days in duration. One patient died from complications of varicella pneumonia after 31 days of hospitalization. The obstetric outcomes of the 7 patients described include 1 non-viable delivery at 20 weeks gestation, 3 term deliveries, 2 preterm deliveries, and 1 patient who has not yet delivered. All of the patients presented were treated with intravenous acyclovir therapy. Of the patients described, 3 required intubation and ventilatory support. Other complications encountered include disseminated intravascular coagulation (DIC), adult respiratory distress syndrome (ARDS), metabolic encephalopathy, pneumothorax, superimposed bacterial pneumonia, and sepsis. Conclusion: The course and treatment of varicella pneumonia complicating pregnancy are discussed. Current recommendations regarding the use of varicella-zoster immune globulin (VZIG) are also reviewed. PMID:18476122

Flexible and semirigid ureteroscopy (URS) are widely performed for the treatment of upper tract calculi and tumors. Ureteral avulsion is a rare, but devastating complication of endoscopic stone removal having multiple possible etiologies. Awareness and avoidance of this rare complication depend on identifying responsible mechanisms. This study examines the situations in which ureteral avulsion occurs as described anonymously in the Manufacturer and User facility Device Experience (MAUDE) database. The MAUDE database was systematically reviewed to account for all reported complications of flexible and semirigid URS. Keywords "ureteroscopy, injury, death, malfunction and other" were entered in the database and medical device reports were reviewed to capture any cases resulting in ureteral avulsion. Attention was paid to the type of ureteroscope involved and the mechanism for avulsion. A total of 104 entries were found detailing the reported complications of flexible and semirigid URS. Ureteral avulsion was clearly noted in six reports with flexible (2) and semirigid ureteroscopes (4). Potential mechanisms included locked deflection of a flexible ureteroscope (1), bunching of the distal bending rubber in a flexible ureteroscope (1), scabbard avulsion (3), and stone basketing (1). Although the incidence of ureteral avulsion cannot truly be determined from this study, some potentially novel mechanisms for this rare complication are observed. This may target future educational efforts to maximize awareness and avoidance of this complication.

Hypertension complicating diabetic pregnancies: pathophysiology, management, and controversies.

Hypertensive disorders of pregnancy (HDP), including pre-existing hypertension, gestational hypertension, and preeclampsia, further complicate already high-risk pregnancies in women with diabetes mellitus (DM). Women with both pre-existing and gestational diabetes are at increased risk for HDP, leading to higher maternal and fetal morbidity. Further, particularly in diabetic women and women with a history of gestational diabetes, HDP significantly increases the risk for future cardiovascular events. For clinicians, women with hypertension and diabetes during pregnancy pose a management challenge. Specifically, preconception management should stress strict control of glycemia, blood pressure, and prevention of diabetic complications, specifically nephropathy, which specifically increases the risk for preeclampsia. During gestation, clinicians must be aware of potential maternal and fetal complications associated with various anti-hypertensive therapies, including known fetotoxicity of ACE inhibitors and ARBs when given in the 2nd or 3rd trimester, and the risks and benefits of expectant management versus delivery in cases of severe gestational hypertension or preeclampsia. Indeed, diabetic women must be followed closely prior to conception and throughout gestation to minimize the risk of HDP and its associated complications. © 2011 Wiley Periodicals, Inc.

Vaginal mesh complications necessitating excision are increasingly prevalent. We aim to study whether subclinical chronically infected mesh contributes to the development of delayed-onset mesh complications or recurrent urinary tract infections (UTIs). Women undergoing mesh removal from August 2013 through May 2014 were identified by surgical code for vaginal mesh removal. Only women undergoing removal of anti-incontinence mesh were included. Exclusion criteria included any women undergoing simultaneous prolapse mesh removal. We abstracted preoperative and postoperative information from the medical record and compared mesh culture results from patients with and without mesh extrusion, de novo recurrent UTIs, and delayed-onset pain. One hundred seven women with only anti-incontinence mesh removed were included in the analysis. Onset of complications after mesh placement was within the first 6 months in 70 (65%) of 107 and delayed (≥6 months) in 37 (35%) of 107. A positive culture from the explanted mesh was obtained from 82 (77%) of 107 patients, and 40 (37%) of 107 were positive with potential pathogens. There were no significant differences in culture results when comparing patients with delayed-onset versus immediate pain, extrusion with no extrusion, and de novo recurrent UTIs with no infections. In this large cohort of patients with mesh removed for a diverse array of complications, cultures of the explanted vaginal mesh demonstrate frequent low-density bacterial colonization. We found no differences in culture results from women with delayed-onset pain versus acute pain, vaginal mesh extrusions versus no extrusions, or recurrent UTIs using standard culture methods. Chronic prosthetic infections in other areas of medicine are associated with bacterial biofilms, which are resistant to typical culture techniques. Further studies using culture-independent methods are needed to investigate the potential role of chronic bacterial infections in delayed vaginal mesh complications.

Balloon-occluded Retrograde Transvenous Obliteration (BRTO): Preprocedural Evaluation and Imaging

Al-Osaimi, Abdullah M. S.; Sabri, Saher S.; Caldwell, Stephen H.

2011-01-01

Patients undergoing balloon retrograde transvenous obliteration (BRTO) are mostly decompensated cirrhotic with either bleeding gastric varices (GV) or hepatic encephalopathy. It is crucial that clinicians are up-to-date with the assessments needed prior to BRTO to anticipate and prevent complications, and to deliver critical quality care. These patients will require preprocedural assessments and management, including endoscopic, clinical, laboratory, and imaging evaluation. Endoscopic evaluation is mandatory prior to BRTO, and it is highly recommended that it be performed at the same institution where BRTO will be performed. It is essential that clinicians are aware of the potential benefits and complications that may result from BRTO. These complications should be anticipated and prevented when possible. For GV bleeders, there should be consideration of a transvenous intrahepatic portosystemic shunt (TIPS) during or before BRTO in patients with refractory ascites or pleural effusion, as well as endoscopic banding or a TIPS in patients with high-risk esophageal varices. Patients undergoing BRTO are usually complicated and require a team approach. In this article, the authors address these assessment and preparatory management and planning procedures prior to the BRTO procedure as well as expected outcomes and potential complications.

2017-09-01

Collagenase Clostridium histolyticum (CCH) injection and manipulation is a relatively new method for treating Dupuytren contracture that is growing in popularity. Although side effects such as swelling and ecchymosis are common, they are typically mild and self-limited. Major complications are rare but have included flexor tendon rupture and complex regional pain syndrome. This study describes a case report of 2 patients seen at our institution. Here, we report 2 patients seen at our institution each with different, yet serious complications after CCH injection and manipulation. One patient had extensive skin loss and chose amputation over reconstruction. The other patient had loss of perfusion and required finger amputation. Although it is unclear how directly the administration of CCH is connected to the observed complications, physicians should recognize the potential for serious rare complications in any treatment of Dupuytren contracture.

Acute mastoiditis (AM) is a suppurative infection of the mastoid air cells, representing the most frequent complication of acute otitis media. AM remains an important entity in children due to its potential complications and sequelae. We aim to describe the cases of AM admitted at our department, identify risk factors potentially associated with complications and analyse the changes in clinical approach of AM over time. Case review of clinical files of children admitted with acute mastoiditis from June 1996 to May 2013 at a Lisbon metropolitan area hospital. Data was divided into two groups (prior and after May 2005) in order to evaluate changes in AM approach over the years. 135 AM episodes were included. The median age was 3.8 years and 42% children were less than 24 months of age. Symptoms at presentation included fever (69%), ear pain (56%) and otorrhea (40%). Complications occurred in 22% patients and were more common in children under 24 months (33% vs 15%, p ≤ 0.01). Leukocyte count was significantly higher in children with complications (16.7 vs 14.5 × 10 9 /μL, p ≤ 0.05) as was C-Reactive Protein value (13 vs 6.3 mg/dL, p ≤ 0.001). There was a significant association between the development of complications and C-Reactive Protein value at admission (OR 1.892; IC95%: 1.018-2.493, p ≤ 0.01). The optimal cut-off value was 7.21 mg/dL. Over time there was a significant increase in middle ear cultures obtained by tympanocentesis during surgery (2% vs 16%, p ≤ 0,01) and also a decrease in the use of broad spectrum antibiotherapy as initial treatment (52% vs 25%,p ≤ 0,001). Children under 24 months, with high leukocyte count or with high C-Reactive Protein value should be monitored closely since complications tend to be more frequent. A CRP value of 7.21 mg/dL at admission seems to be a good cut-off to monitor children for potential complications. Throughout the period analysed more cultures were performed allowing identification of the pathogens and implementation of appropriate antibiotic therapy. Copyright © 2016 Elsevier Ireland Ltd.

To evaluate perioperative considerations and post-operative complications associated with parathyroidectomy in the pediatric population. The Kids' Inpatient Database 21 (KID) was searched for patients who underwent parathyroidectomy in 2009 and 2012. Patient demographics, hospital stay, associated charges, and post-operative adverse sequelae were evaluated in all patients and included patient comorbidity and additional procedure requirement analysis. There were 182 patients extrapolating to 262 parathyroidectomies over the two years analyzed. Although a minority of patients were male (45.4%), these patients had greater rates of complications, length of stay, and hospital charges. Importantly, minorities and younger patients (≤15y) also had more complicated post-operative courses. The lengths of stay for patients experiencing post-operative altered mental status (18.7d), post-operative infection (15.5d), respiratory complications (19d), and cardiac complications (13d) were significantly increased compared to individuals without major complications (3.4d) (p < 0.001). Patients with pre-existing chronic kidney disease, dialysis-dependence, and bone sequelae (most commonly from hungry bone syndrome) also had significantly lengthier stays and greater associated costs. Findings from this analysis can be included in a comprehensive pre-operative informed consent process between physicians and patients discussing perioperative considerations and potential complications of parathyroidectomy. Males, younger children, and patients with preexisting renal conditions experienced lengthier and more complicated hospital stays, suggesting the need for closer monitoring of these cohorts.

Cerebrospinal fluid (CSF) rhinorrhea and encephaloceles are rare complications of craniofacial advancement procedures performed in patients with craniofacial dysostoses (CD) to address the ramifications of their midface hypoplasia including obstructed nasal airway, exorbitism, and impaired mastication. Surgical repair of this CSF rhinorrhea is complicated by occult elevations in intracranial pressure (ICP), potentially necessitating open, transcranial repair. We report the first case in otolaryngology literature of a patient with Crouzon syndrome with late CSF rhinorrhea and encephalocele formation after previous LeFort III facial advancement surgery. Describe the case of a patient with Crouzon syndrome who presented with CSF rhinorrhea and encephaloceles as complications of Le Fort III facial advancement surgery. Review the literature pertaining to the incidence and management of post-operative CSF rhinorrhea and encephaloceles. Analyze issues related to repair of these complications, including occult elevations in ICP, the utility of perioperative CSF shunts, and the importance of considering alternative repair schemes to the traditional endonasal, endoscopic approach. Review of the literature describing CSF rhinorrhea and encephalocele formation following facial advancement in CD, focusing on management strategies. CSF rhinorrhea and encephalocele formation are rare complications of craniofacial advancement procedures. Occult elevations in ICP complicate the prospect of permanent surgical repair, potentially necessitating transcranial repair and the use of CSF shunts. Though no consensus exists regarding the utility of perioperative CSF drains, strong associations exist between elevated ICP and failed surgical repair. Additionally, the anatomic changes in the frontal and ethmoid sinuses after facial advancement present a challenge to endoscopic repair. Otolaryngologists should be aware of the possibility of occult elevations in ICP and sinonasal anatomic abnormalities when repairing CSF rhinorrhea in patients with CD. Clinicians should consider CSF shunt placement and carefully weigh the advantages of the transcranial approach versus endonasal, endoscopic techniques.

Introduction Shunting is a well-accepted method of maintaining cerebral perfusion during carotid endarterectomy (CEA). Nonetheless, shunt insertion may lead to complications including arterial dissection, embolization, and thrombosis. We present a complication of shunt insertion consisting of arterial wall rupture, not reported previously. Presentation of case A 78-year-old woman underwent CEA combined with coronary artery bypass grafting (CABG). At the time of shunt insertion an arterial rupture at the distal tip of the shunt was detected and was repaired via a small saphenous vein patch. Eversion CEA and subsequent CABG completed the procedure whose postoperative course was uneventful. Discussion Shunting during combined CEA-CABG may be advisable to assure cerebral protection from possible hypoperfusion due to potential hemodynamic instability of patients with severe coronary artery disease. Awareness and prompt management of possible shunt-related complications, including the newly reported one, may contribute to limiting their harmful effect. Conclusion Arterial wall rupture is a possible, previously not reported, shunt-related complication to be aware of when performing CEA. PMID:26255001

This study evaluates baseline patient characteristics and surgical parameters for risk factors of medical complications in ASD patients received posterior long level internal fixation. Analysis of consecutive patients who underwent posterior long-level instruction fixation for adult degenerative scoliosis (ADS) with a minimum of two year follow-up was performed. Pre-operative risk factors, intraoperative variables, peri-operative radiographic parameters, and surgical-related risk factors were collected to analyze the effect of risk factors on medical complications. Patients were separated into groups with and without medical complication. Then, complication group was further classified as major or minor medical complications. Potential risk factors were identified by univariate testing. Multivariate logistic regression was used to evaluate independent predictors of medical complications. One hundred and thirty-one ADS patients who underwent posterior long segment pedicle screws fixation were included. Total medical complication incidence was 25.2%, which included infection (12.2%), neurological (11.5%), cardiopulmonary (7.6%), gastrointestinal (6.1%), and renal (1.5%) complications. Overall, 7.6% of patients developed major medical complications, and 17.6% of patients developed minor medical complications. The radiographic parameters of pre-operative and last follow-up had no significant difference between the groups of medical complications and the major or minor medical complications subgroups. However, the incidence of cerebrospinal fluid leak (CFL) in patients who without medical complications was much lower than that with medical complications (18.4 vs. 42.4%, P = 0.005). Independent risk factors for development of medical complications included smoking (OR = 6.45, P = 0.012), heart disease (OR = 10.07, P = 0.012), fusion level (OR = 2.12, P = 0.001), and length of hospital stay (LOS) (OR = 2.11, P = 0.000). Independent risk factors for development of major medical complications were diabetes (OR 6.81, P = 0.047) and heart disease (OR = 5.99, P = 0.049). Except for the last follow-up, Oswestry Disability Index and visual analog scale of the patient experienced medical complications trend higher score; the clinical outcomes have no significant difference between the medical and major complications groups. Heart disease comorbidity is an independent risk factor for both medical and major medical complications. Smoking, fusion level, and LOS are independent risk factors for medical complication. Diabetes is the independent risk factors for major medical complications.

Treatment of psychological factors in a child with difficult asthma: a case report.

Difficult asthma is defined as the persistence of asthma symptoms, abnormal pulmonary function showing airway obstruction, and continued requirement for short-acting bronchodilator therapy, despite adequate treatment with inhaled corticosteroids. It calls for a thorough evaluation of the patient to look into alternate and complicating diagnoses. The authors report a case of a 9-year-old patient with difficult asthma who failed to respond to conventional therapy. Although it was recognized that he had a number of potential medical complicating factors including allergies, chronic sinusitis, and gastroesophageal reflux, a psychological intervention using hypnosis ultimately appeared to help alleviate his symptoms completely. Thus, psychological evaluation and intervention should be considered early in the course of management of a patient with difficult asthma, because it may help avoid time-consuming and expensive investigations of potential complicating factors, and it may yield rapid improvement in the patient's clinical condition.

Common complementary and alternative therapies with potential use in dermatologic surgery: risks and benefits.

PubMed

Reddy, Kavitha K; Grossman, Lauri; Rogers, Gary S

2013-04-01

Ambulatory surgery patients often use complementary and alternative medicine (CAM) therapies. CAM therapies may create beneficial and detrimental perioperative conditions. We sought to improve knowledge of CAM effects in dermatologic surgery, allowing dermatologists to potentially capitalize on therapeutic actions and to mitigate complications. PubMed literature search of CAM therapies in dermatologic and surgical settings was performed. Common CAM therapies with possible effects on dermatologic surgery were selected. Beneficial and detri-mental effects were reviewed. A myriad of products may be used perioperatively by the patient. Therapies appearing to have some evidence for potential benefit include bromelain, honey, propolis, arnica, vitamin C and bioflavonoids, chamomile, aloe vera gel, grape seed extract, zinc, turmeric, calendula, chlorella, lavender oil, and gotu kola. Potential complications vary according to product and include platelet inhibition, contact dermatitis and, in rare cases, systemic toxicity. This review focuses on CAM having significant published studies evaluating efficacy for wound healing, anti-inflammatory, antipurpuric, or perioperative-related use. Most published studies have been small and often have design flaws. The scope of CAM is large and not all therapies are discussed. Selected CAM therapies have been reported to promote wound healing, reduce edema or purpura, and provide anti-inflammatory effects. Because of high rates of CAM use, surgeons should familiarize themselves with common uses, potential benefits, and complications. Further study of effects in the dermatologic surgery setting may improve the patient-doctor relationship and enhance outcomes. Copyright © 2011 American Academy of Dermatology, Inc.

2018-05-01

Magnetic resonance imaging-guided stereotactic laser ablation of intracranial targets, including brain tumors, has expanded dramatically over the past decade, but there have been few reports of complications, especially those occurring in a delayed fashion. Laser ablation of subependymal giant cell astrocytomas (SEGAs) is an attractive alternative to maintenance immunotherapy in some children with tuberous sclerosis complex (TSC); however, the effect of treatment on disease progression and the nature and frequency of potential complications remains largely unknown. The authors report the case of a 5-year-old boy with TSC who underwent stereotactic laser ablation of a SEGA at the right foramen of Monro on 2 separate occasions. After the second ablation, immediate posttreatment MRI revealed gadolinium extravasation from the tumor into the lateral ventricle. Nine months later, the patient presented with papilledema and delayed obstructive hydrocephalus secondary to intraventricular adhesions causing a trapped right lateral ventricle. This was successfully treated with endoscopic septostomy. The authors discuss the potential cause and clinical management of a delayed complication not previously reported after a relatively novel surgical therapy.

Schizophrenia is an important psychical disease of multifactorial origin and not yet clear etiology. In prenatal and perinatal period some potential risk factors for schizophrenia are taken into consideration. Case-control study of 815 subjects, 407 cases and 408 controls was performed in 2013 to 2015. In this study environmental and genetic risk factors were evaluated including potential risk factors of prenatal and perinatal period. Statistically important difference was found in child-birth done by cesarean section (p = 0.009) and in patients with schizophrenia were 15.7% complications in the course of childbirth (p < 0.001). Hypoxia, passed umbilical cord were the most frequent complications. In prenatal period premature childbirth, injury and psychical complications were the most frequent. On the other hand difference in weight and length of newborns, breast feeding and infection during pregnancy were found not statistically important. In this study statistically important diference were found in way of carrying childbirth and in some complications during pregnancy and delivery. Influence of infection during pregnancy and influence of weight and length of newborn were not demonstrated.

Hermansky-Pudlak syndrome (HPS), a rare autosomal-recessive disorder encompassing multiple organs, is characterized by oculocutaneous albinism, platelet storage pool deficiency resulting in bleeding diathesis, and ceroid lipofuscin deposition which can lead to pulmonary fibrosis, colitis, cardiomyopathy and renal failure. Pregnancy in a patient with HPS can produce multiple complications such as peripartum hemorrhage and difficulties with administration of anesthesia, either regional or general. We present the case of a patient with HPS also complicated by spontaneous triplet pregnancy. A multidisciplinary approach, including the involvement of obstetric, anesthesia, and hematology teams, is the ideal for an HPS patient with the potential for multiple complications in the peripartum period.

Endothelin (ET) peptides perform several physiological, vascular, and nonvascular functions and are widely distributed in a number of tissues. They are altered in several disease processes including diabetes. Alteration of ETs have been demonstrated in organs of chronic diabetic complications in both experimental and clinical studies. The majority of the effects of ET alteration in diabetes are due to altered vascular function. Furthermore, ET antagonists have been shown to prevent structural and functional changes induced by diabetes in animal models. This review discusses the contribution of ETs in the pathogenesis and the potential role of ET antagonism in the treatment of chronic diabetic complications. PMID:12546275

Urethral obliteration is an uncommon complication of urethral injury and is usually associated with pelvic fracture. Until recently, surgical reconstruction was the only means available to restore urethral continuity. Although formal urethroplasty may be associated with excellent success rates, impotence and incontinence are potential complications. Endoscopic urethroplasty has recently evolved into a suitable alternative to surgical reconstruction in selected cases. We review here the technique of endoscopic urethroplasty and include our initial results.

Retrospective cohort study among Medicare beneficiaries who underwent posterior lumbar interbody fusion (PLIF) surgery. To identify the complication rates associated with the use of bone morphogenetic protein 2 (BMP2) in PLIF. Human BMP2 is commonly used in the "off-label" manner for various types of spine fusion procedures, including PLIF. However, recent studies have reported potential complications associated with the recombinant human BMP2 (rhBMP2) use in the posterior approach. Medicare records within the PearlDiver database were queried for patients undergoing PLIF procedure with and without rhBMP2 between 2005 and 2010. We evaluated complications within 1 year postoperatively. Chi-square was used to compare the complication rates between the 2 groups. A total of 8609 patients underwent PLIF procedure with or without rhBMP2. Individual complication rates in the rhBMP2 group ranged from 0.45% to 7.68% compared with 0.65% to 10.99 in the non-rhBMP2 group. Complication rates for cardiac, pulmonary, lumbosacral neuritis, infection, wound, and urinary tract (include acute kidney failure and post-operative complications) were significantly lower in the rhBMP2 group ( P < .05). There was no difference in the rates of central nervous system complications or radiculitis between the 2 groups. Our data showed that the patients who received rhBMP2 had lower complication rates compared to the non-rhBMP2 group. However, use of rhBMP2 was associated with a higher rate of pseudarthrosis. We did not observe any difference in radiculitis and central nervous system complications between the groups.

Upper arm deformities secondary to massive weight loss or senile elastosis have led to an increased demand for aesthetic contouring procedures such as brachioplasty. The records of all patients who underwent a brachioplasty procedure from a multipractice medical center were reviewed. Outcomes measured included patient demographics, operative interventions, and postoperative course. Ninety-six patients were analyzed. Fifty-three patients (55.2 percent) underwent a concomitant procedure, with 53.1 percent undergoing arm liposuction at the time of brachioplasty. Major and minor complications rates were 17.7 percent and 44.8 percent, respectively. Common complications included hypertrophic scarring (24.0 percent) and infection (14.6 percent). The total revision rate was 22.9 percent, with residual contour deformity (40.9 percent of revisions) and hypertrophic scarring (36.4 percent of revisions) representing the most common causes for revision. Patients who underwent a previous bariatric procedure were at an increased risk of developing a major complication (p = 0.02). Concomitant upper arm liposuction and concomitant procedures were not associated with a significantly increased complication rate. Brachioplasty, despite being an effective treatment for contour irregularities of the upper arm, is associated with significant revision and complication rates. Post-bariatric surgery patients should be informed of the potential for increased complications. Additional procedures performed at the time of brachioplasty do not significantly increase complications. Liposuction of the upper arm can be performed safely in conjunction with brachioplasty.

Background Neutropenic patients are susceptible to any anorectal disease, and symptomatic anorectal disease afflicts 2–32% of oncology patients. Perianal infections are the most feared complication, considering the lack of natural defense against infectious microorganisms. When septic complications develop, the anorectal disease is potentially fatal, especially in neutropenic patients in whom mortality rates range between 11–57%. Although anorectal diseases are a frequent complication with potentially fatal outcomes among patients with hematologic diseases, sufficient data are not available in the literature. In this study, we aimed to investigate the anorectal complications developing during the neutropenic period in patients with hematologic diseases. Methods A total of 79 patients whose neutropenic period (absolute neutrophil count <500/mcL) continued for 7 days, or longer were included in the study. Results A total of 34 patients out of 79 (43%) were detected to develop anorectal complications, of them 6 (7.6%) developed an anorectal infection. The patients were characterized according to the hematological disease and its status (active or not), the type of treatment and the presence of a history of an anorectal pathology before the onset of the hematologic disease. Nineteen (24.1%) patients had the history of anorectal disturbances before diagnosis of the hematologic disease, and recurrence of an anorectal pathology was found in 14 out of 19 patients(73.7%). In addition, the overall mortality rate was higher among the patients who developed anorectal complications compared to another group (41.2% vs. 22.2%, p=0.059). Conclusion Anorectal pathology is a common complication with high recurrence rate in neutropenic patients. Perianal infections are important as they can cause life-threatening outcomes although they are relatively rare among all anorectal complications. Therefore perianal signs and symptoms should be meticulously evaluated concerning early diagnosis and treatment. PMID:26977278

Complications of retrograde balloon cautery endopyelotomy.

Schwartz, B F; Stoller, M L

1999-11-01

Adult ureteropelvic junction obstruction is increasingly managed with endoscopic techniques. Retrograde balloon cautery endopyelotomy is quick, requires minimal hospital stay and allows most patients a rapid return to work. The complication rate of retrograde balloon cautery endopyelotomy ranges from 13 to 34%, with vascular injury in 0 to 16% of patients. We report 5 uncommon complications, including 4 vascular injuries, that clinicians should be familiar with when using this technique. We reviewed 52 retrograde endoscopic endopyelotomy procedures performed during a 5-year period. There were 5 uncommon complications. Accessory lower pole renal artery injuries occurred in 3 patients, 1 of whom presented 12 days after endopyelotomy. Embolization was successfully performed in all 3 cases and none had subsequent hypertension. In 1 case a right ovarian vein laceration was not evident on preoperative or postoperative angiography. Emergency post-embolization abdominal exploration revealed a 2 mm. injury to the right ovarian vein before entering the right renal vein close to the ureteropelvic junction incision. Nephrectomy and ovarian vein ligature were curative. In 1 case the electrocautery wire broke intracorporeally after firing, resulting in a bobby pin-like configuration. Successful removal was accomplished by twisting the catheter and wrapping the wire around the tip, enabling atraumatic removal. Retrograde balloon cautery endopyelotomy is an emerging technology with potential adverse outcomes. The complications we noted are complex and potentially life threatening. Awareness of these complications may help avoid poor outcomes and expedite appropriate treatment.

The incidence of central venous catheter (CVC)-related complications reported in pediatric sarcoma patients is not established as reports in available literature are limited. The analysis of risk factors is part of the strategy to reduce the incidence of CVC complications. The objective of this study was to determine the incidence of CVC complications in children with bone sarcomas and if defined clinical variables represent a risk factor. During an 8-year period, 155 pediatric patients with bone sarcomas were prospectively followed up for CVC complications. Incidence and correlation with clinical features including gender, age, body mass index, histology, disease stage, and use of thromboprophylaxis with low-molecular-weight heparin were analyzed. Thirty-three CVC complications were recorded among 42 687 CVC-days (0.77 per 1000 CVC-days). No correlation between the specific clinical variables and the CVC complications was found. A high incidence of CVC-related sepsis secondary to gram-negative bacteria was observed. The analysis of CVC complications and their potential risk factors in this sizable and relatively homogeneous pediatric population with bone sarcomas has led to the implementation of a multimodal approach by doctors and nurses to reduce the incidence and morbidity of the CVC-related infections, particularly those related to gram-negative bacteria. As a result of this joint medical and nursing study, a multimodal approach that included equipping faucets with water filters, the reeducation of doctors and nurses, and the systematic review of CVC protocol was implemented.

One of the earliest but often unaddressed signs of facial aging is volume loss in the temple. Treatment of the area can produce satisfying results for both patient and practitioner. Safe injection requires explicit knowledge of the anatomy to avoid complications related to the multitude of vessels that course throughout the region at various depths. The authors aim to detail the anatomy of the area and provide a safe and easy-to-follow method for injection. The authors review the relevant anatomy of the temporal region and its application to cosmetic filler injections. The authors describe an easy-to-follow approach for a safe and effective injection window based on numerous anatomical studies. Injection in this area is not without risk, including potential blindness. The authors review the potential complications and their treatments. Hollowing of the temple is an early sign of aging that, when corrected, can lead to significant patient and practitioner satisfaction. Proper anatomically knowledge is required to avoid potentially severe complications. In this study, the authors present a reliable technique to safely and effectively augment this often undertreated area of the aging face.

The pharmacoeconomics of peri-operative beta-blocker therapy.

Biccard, B M; Sear, J W; Foëx, P

2006-01-01

It is widely recommended that beta-blockade be used peri-operatively as it may reduce the incidence of postoperative cardiovascular complications including death. However, there are few data concerning the cost-effectiveness of such strategies. We have analysed the pharmacoeconomics of acute beta-blockade using data from eight prospective peri-operative studies in which patients underwent elective non-cardiac surgery, and in which the incidence of adverse side-effects of treatment, as well as clinical outcomes, have been reported. The costs of treatment were based on the NHS reference costs for 2004. From these data, the number-needed-to-treat (NNT) to prevent a major cardiovascular complication (including cardiovascular death) in high-risk patients was 18.5. This is comparable to the NNT for peri-operative statin therapy. The incremental cost of peri-operative beta-blockade (costs of drug acquisition and of treating associated adverse drug events) was 67.80 pounds sterling per patient. This results in a total cost of 1254.30 pounds sterling per peri-operative cardiovascular complication prevented. However, there is evidence that in patients at lower cardiovascular risk, beta-blockers may be potentially harmful, since their adverse effects (hypotension, bradycardia) may outweigh their potential cardioprotective effects.

Therapeutic advances: Single incision laparoscopic hepatopancreatobiliary surgery

Chang, Stephen Kin Yong; Lee, Kai Yin

2014-01-01

Single-port laparoscopic surgery (SPLS) is proposed to be a step towards minimizing the invasiveness of surgery, and has since gained popularity in several surgical sub-specialties including hepatopancreatobiliary surgery. SPLS has since been applied to cholecystectomy, liver resection as well as pancreatectomy for a multitude of pathologies. Benefits of SPLS over conventional multi-incision laparoscopic surgery include improved cosmesis and potentially post-operative pain at specific time periods and extra-umbilical sites. However, it is also associated with longer operating time, increased rate of complications, and increased rate of port-site hernia. There is no significant difference between length of hospital stay. SPLS has a significant learning curve that affects operating time, rate of conversion and rate of complications. In this article, we review the literature on SPLS in hepatobiliary surgery - cholecystectomy, hepatectomy and pancreatectomy, and offer tips on overcoming potential technical obstacles and minimizing the complications when performing SPLS - surgeon position, position of port and instruments, instrument crossing position, standard hand grip vs reverse hand grip, snooker cue guide position, prevention of incisional hernia. SPLS is a promising direction in laparoscopic surgery, and we recommend step-wise progression of applications of SPLS to various hepatopancreatobiliary surgeries to ensure safe adoption of the surgical technique.

The last decade has seen ongoing evolution and use of cardiac rhythm management devices, including pacemakers, cardiac resynchronisation therapy, implantable cardioverter defibrillators and loop recorders. General practitioners are increasingly involved in follow-up and management of patients with these devices. The aim of this article is to provide an overview of different cardiac rhythm management devices, including their role, implant procedure, post-procedural care, potential complications and follow‑up. We also include practical advice for patients regarding driving, exercise, sexual intimacy and precautions with regards to electromagnetic interference. Cardiac rhythm management devices perform many functions, including bradycardia pacing, monitoring for arrhythmias, cardiac resynchronisation for heart failure, defibrillation and anti-tachycardia pacing for tachyarrhythmias. Concerns regarding potential device-related complications should be discussed with the implanting physician. In the post-implant period, patients with cardiac rhythm management devices can expect to lead normal, active lives. However, caution must occasionally be exercised in certain situations, such as near appliances with electromagnetic interference. Future innovations will move away from transvenous leads to leadless designs with combinations of different components on a 'modular' basis according to the function required.

Complications of growth-sparing surgery in early onset scoliosis.

Akbarnia, Behrooz A; Emans, John B

2010-12-01

Review of available literature, authors' opinion. To describe complications associated with growth-sparing surgical treatment of early onset scoliosis (EOS). EOS has many potential etiologies and is often associated with thoracic insufficiency syndrome. The growth of the spine, thorax, and lungs are interrelated, and severe EOS typically involves disturbance of the normal development of all 3. Severe EOS may be treated during growth with surgical techniques, intended to preserve growth while controlling deformity, the most common of which are spinal "growing rods" (GR) or "vertical expandable prosthetic titanium rib" (VEPTR). Although presently popular, there is minimal long-term data on the outcome of growth-sparing surgical techniques on EOS. Review. Potential adverse outcomes of GR or VEPTR treatment of EOS include failure to prevent progressive deformity or thoracic insufficiency syndrome, an unacceptably short or stiff spine or deformed thorax, increased family burden of care, and potentially negative psychological consequences from repeated surgical interventions. Neither technique reliably controls all deformity over the entirety of growth period. Infections are common to both GR and VEPTR. Rod breakage and spontaneous premature spinal fusion beneath rods are troublesome complications in GR, whereas drift of rib attachments and chest wall scarring are anticipated complications in VEPTR treatment. Indications for GR and VEPTR overlap, but thoracogenic scoliosis and severe upper thoracic kyphosis are best treated by VEPTR and GR, respectively. Surgeons planning treatment of EOS should anticipate the many complications common to growth-sparing surgery, share their knowledge with families, and use complications as one factor in the complex decision as to when and whether to initiate the repetitive surgeries associated with GR or VEPTR in the treatment of severe EOS.

Urinary tract infections (UTI) are the most common bacterial infections involving lower (cystitis, prostatitis) or upper (pyelonephritis, renal abscess, perinephric abscess) urinary tract. Differentiation of complicated and uncomplicated UTI is usually based on the presence of structural or functional urinary tract abnormalities, which can increase the risk of treatment failure and development of serious complications. Factors that increase the risk are foreign bodies, stones, obstruction, neurogenic bladder, kidney transplantation, immunosuppression, and pregnancy. Complicated UTI includes a spectrum of conditions that increase the risk of treatment failure, as well as of serious complications such as bacteremia and sepsis, perinephric abscess, renal impairment and emphysematous pyelonephritis. To avoid the potentially devastating outcomes, appropriate diagnostic procedures, antibiotic and surgical treatment, and appropriate follow-up are required. The incidence of complicated UTI will grow in the future due to general aging of the population, increasing incidence of diabetes, and ever growing number of immunocompromised and immunosuppressed patients. It is of key importance to recognize complicated UTI on time, and treat it wisely and aggressively to reduce duration of the disease and the risk of antibiotic resistance.

Stroke is a major cause of death and other complications worldwide. In Saudi Arabia, stroke has become an emerging health issue leading to disability and death. However, stroke care including rehabilitation services, in Saudi Arabia lags behind developed countries. Stroke rehabilitation is an essential recovery option after stroke and should start as early as possible to avoid potential complications. The growing evidence on stroke rehabilitation effectiveness in different health care settings and outcome measures used widely are reviewed in this call to action paper. PMID:27744457

A retrospective cohort study. To compare the complications between posterior cervical fusions with and without recombinant human bone morphogenetic protein 2 (rhBMP2). Use of rhBMP2 in anterior cervical spinal fusion procedures can lead to potential complications such as neck edema, resulting in airway complications or neurological compression. However, there are no data on the complications associated with the "off-label" use of rhBMP2 in upper and lower posterior cervical fusion approaches. Patients from the PearlDiver database who had a posterior cervical fusion between 2005 and 2011 were identified. We evaluated complications within 90 days after fusion and data was divided in 2 groups: (1) posterior cervical fusion including upper cervical spine O-C2 (upper group) and (2) posterior cervical fusion including lower cervical spine C3-C7 (lower group). Complications were divided into: any complication, neck-related complications, wound-related complications, and other complications. Of the 352 patients in the upper group, 73 patients (20.7%) received rhBMP2, and 279 patients (79.3%) did not. Likewise, in the lower group of 2372 patients, 378 patients (15.9%) had surgery with rhBMP2 and 1994 patients (84.1%) without. In the upper group, complications were observed in 7 patients (9.6%) with and 34 patients (12%) without rhBMP2. In the lower group, complications were observed in 42 patients (11%) with and 276 patients (14%) without rhBMP2. Furthermore, in the lower group the wound-related complications were significantly higher in the rhBMP2 group (23 patients, 6.1%) compared with the non-rhBMP2 group (75 patients, 3.8%). Our data showed that the use of rhBMP2 does not increase the risk of complications in upper cervical spine fusion procedures. However, in the lower cervical spine, rhBMP2 may elevate the risk of wound-related complications. Overall, there were no major complications associated with the use of rhBMP2 for posterior cervical fusion approaches. Level III.

The objective was to evaluate the management and outcome of patients with anti-Fy(a) at the Ohio State University. A database search for patients with pregnancies complicated only by anti-Fy(a) from 1959 to 2004. Collected information included maternal testing, fetal therapy, and neonatal outcomes. The final data set included 18 pregnancies in 15 women where anti-Fy(a) was the only maternal alloantibody present and the fetus was Fy(a) antigen-positive. Maternal antibody titers of at least 32 and optical density at 450 nm values in modified Liley Zone IIB or III identified all fetuses or neonates with significant hemolytic disease (2/18, 11%). No fetuses had hydrops, and there were no deaths attributed to hemolytic disease of the fetus and newborn. Anti-Fy(a) has the potential to lead to significant fetal hemolysis. Management guidelines developed for D sensitization are appropriate for pregnancies complicated by anti-Fy(a) alloimmunization.

Internal carotid artery rupture caused by carotid shunt insertion.

2015-01-01

Shunting is a well-accepted method of maintaining cerebral perfusion during carotid endarterectomy (CEA). Nonetheless, shunt insertion may lead to complications including arterial dissection, embolization, and thrombosis. We present a complication of shunt insertion consisting of arterial wall rupture, not reported previously. A 78-year-old woman underwent CEA combined with coronary artery bypass grafting (CABG). At the time of shunt insertion an arterial rupture at the distal tip of the shunt was detected and was repaired via a small saphenous vein patch. Eversion CEA and subsequent CABG completed the procedure whose postoperative course was uneventful. Shunting during combined CEA-CABG may be advisable to assure cerebral protection from possible hypoperfusion due to potential hemodynamic instability of patients with severe coronary artery disease. Awareness and prompt management of possible shunt-related complications, including the newly reported one, may contribute to limiting their harmful effect. Arterial wall rupture is a possible, previously not reported, shunt-related complication to be aware of when performing CEA. Copyright © 2015 The Authors. Published by Elsevier Ltd..

CT of inferior vena cava filters: normal presentations and potential complications.

PubMed

Georgiou, Nicholas A; Katz, Douglas S; Ganson, George; Eng, Kaitlin; Hon, Man

2015-12-01

With massive pulmonary embolism (PE) being the first or second leading cause of unexpected death in adults, protection against PE is critical in appropriately selected patients. The use of inferior vena cava (IVC) filters has increased over the years, paralleling the increased detection of deep venous thrombosis (DVT) and PE by improved and more available imaging techniques. The use of IVC filters has become very common as an alternative and/or as a supplement to anticoagulation, and these filters are often seen on routine abdominal CT, including in the emergency setting; therefore, knowledge of the normal spectrum of findings of IVC filters by the radiologist on CT is critical. Additionally, CT can be used specifically to identify complications related to IVC filters, and CT may alternatively demonstrate IVC filter-related problems which are not specifically anticipated clinically. With multiple available IVC filters on the US market, and even more available outside of the USA, it is important for the emergency and the general radiologist to recognize the different models and various appearances and positioning on CT, as well as their potential complications. These complications may be related to venous access, but also include thrombosis related to the filter, filter migration and penetration, and problems associated with filter deployment. With the increasing number of inferior vena cava filters placed and their duration within patients increasing over time, it is critical for emergency and other radiologists to be aware of these findings on CT.

Delayed diaphragmatic herniation masquerading as a complicated parapneumonic effusion.

PubMed

Tsang, J; Ryan, F

1999-01-01

Injury to the diaphragm following blunt or penetrating thoracoabdominal trauma is not uncommon. Recognition of this important complication of trauma continues to be a challenge because of the lack of specific clinical and plain radiographic features, the frequent presence of other serious injuries and the potential for delayed presentation. Delayed diaphragmatic herniation often presents with catastrophic bowel obstruction or strangulation. Early recognition of diaphragmatic injury is required to avoid this potentially lethal complication. The case of a 35-year-old man with a history of a knife wound to the left flank 15 years previously, who presented with unexplained acute hypoxemic respiratory failure and a unilateral exudative pleural effusion that was refractory to tube thoracostomy drainage, is reported. After admission to hospital, he developed gross dilation of his colon; emergency laparotomy revealed an incarcerated colonic herniation into the left hemithorax. Interesting clinical features of this patient's case included the patient's hobby of weightlifting, a persistently deviated mediastinum despite drainage of the pleural effusion and deceptive pleural fluid biochemical indices.

Pragmatic approach to the clinical work-up of patients with putative allergic disease to metallic orthopaedic implants before and after surgery.

Allergic complications following insertion of metallic orthopaedic implants include allergic dermatitis reactions but also extracutaneous complications. As metal-allergic patients and/or surgeons may ask dermatologists and allergologists for advice prior to planned orthopaedic implant surgery, and as surgeons may refer patients with complications following total joint arthroplasty for diagnostic work-up, there is a continuous need for updated guidelines. This review presents published evidence for patch testing prior to surgery and proposes tentative diagnostic criteria which clinicians can rely on in the work-up of patients with putative allergic complications following surgery. Few studies have investigated whether subjects with metal contact allergy have increased risk of developing complications following orthopaedic implant insertion. Metal allergy might in a minority increase the risk of complications caused by a delayed-type hypersensitivity reaction. At present, we do not know how to identify the subgroups of metal contact allergic patients with a potentially increased risk of complications following insertion of a metal implant. We recommend that clinicians should refrain from routine patch testing prior to surgery unless the patient has already had implant surgery with complications suspected to be allergic or has a history of clinical metal intolerance of sufficient magnitude to be of concern to the patient or a health provider. The clinical work-up of a patient suspected of having an allergic reaction to a metal implant should include patch testing and possibly in vitro testing. We propose diagnostic criteria for allergic dermatitis reactions as well as noneczematous complications caused by metal implants. © 2011 The Authors.

Atrial fibrillation (AF) ablation is increasingly common, but is associated with potential major complications. Technology, experience, and protocols have evolved significantly in recent times, and may have impacted procedural safety. We sought to compare AF ablation safety profiles, including complication rates and fluoroscopy times in a "modern" versus "historical" cohort. We evaluated consecutive patients undergoing AF ablation from a modern cohort (MC) from 2014 to 2015 and a historic cohort (HC) from 2009 to 2011 for complications. Major complications were categorized according to Heart Rhythm Society guidelines. We included 1,425 patients, 726 in the HC and 699 in the MC. The MC was older, had more OSA and less valvular AF. Fifty-two (3.5%) procedures suffered major complications across the cohorts, with significantly fewer in the MC (5.0% vs. 2.3%, P  =  0.007). The largest reductions were seen in vascular, hemorrhagic, ischemic stroke, and perforation/tamponade related complications. Periprocedural antiplatelets drugs (aHR 2.1 [95 CI 1.1-3.9], P  =  0.02) and force-sensing catheters (aHR 0.4 [95 CI 0.2-0.9], P  =  0.03) were independently related to major complication rates. Direct oral anticoagulants and uninterrupted anticoagulation were not associated with complications. There was a decrease in both fluoroscopy (-17.4 minutes [95 CI 19.2-15.6], P < 0.0001) and radiofrequency ablation times (-561 seconds [95CI -750 to -371], P < 0.0001). The safety profile of AF ablation has improved significantly in less than a decade. © 2018 Wiley Periodicals, Inc.

Fluid Extravasation in Shoulder Arthroscopic Surgery: A Systematic Review

2018-01-01

Background: Arthroscopic surgery of the shoulder joint has become increasingly more common given its advantages over open surgery; however, one rare but potentially life-threatening complication is fluid extravasation into the surrounding tissues, causing edema, respiratory compromise, abnormal results on laboratory blood tests, and possibly death. Currently, no systematic review exists that summarizes the existing clinical research on this topic. Purpose: To perform a systematic review on fluid extravasation as a complication of shoulder arthroscopic surgery, specifically assessing clinical presentation, risk factors, management, and outcomes. Study Design: Systematic review; Level of evidence, 4. Methods: Two reviewers independently searched 3 databases (PubMed, Ovid [MEDLINE], and Embase) from database inception until July 1, 2017. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist guided the reporting and data abstraction. The methodological quality of these studies was assessed using the Methodological Index for Non-Randomized Studies (MINORS) checklist. The results are presented in a narrative summary fashion using descriptive statistics including ranges and agreement statistics. Results: A total of 26 studies (20 case reports, 4 case series, and 2 prospective comparative studies) encompassing 205 patients (mean age, 50.8 years [range, 15-83 years]) were included. The most common signs of fluid extravasation included chest wall swelling (n = 86) and neck swelling (n = 116). In 32 patients, observation alone was sufficient. Other patients required airway intubation (n = 16), diuretics (n = 7), steroids (n = 1), and percutaneous drainage of fluid (n = 1). Clinical edema resolved after 2 to 48 hours, and patients were discharged 1 to 20 days postoperatively. Serious complications included transfer to the intensive care unit (n = 14), anterior interosseous nerve palsy (n = 4), rhabdomyolysis (n = 1), and death (n = 1). Conclusion: Fluid extravasation has the potential to be a life-threatening complication of shoulder arthroscopic surgery; however, it is most commonly managed nonoperatively, and symptoms typically resolve with no evidence of long-term complications. Intraoperative surgical decisions, such as minimizing the surgical time and volume of irrigation fluid used, may limit fluid extravasation, while careful intraoperative monitoring may facilitate prompt diagnosis and management to optimize patient outcomes.

Potential roles for uncoupling proteins in HIV lipodystrophy.

PubMed

Nolan, David; Pace, Craig

2004-07-01

The 'HIV lipodystrophy syndrome' consists of several distinct components, including lipoatrophy (pathological subcutaneous fat loss), lipohypertrophy (abdominal/visceral adiposity), and metabolic complications including insulin resistance and dyslipidemia. Lipoatrophy appears to represent an adipose tissue-specific form of mitochondrial toxicity associated strongly with stavudine NRTI therapy, whilst the 'metabolic syndrome' phenotype is associated with HIV protease inhibitor therapy. In this context, the role of uncoupling proteins (UCPs) in modulating resting energy expenditure in response to elevated fatty acid flux associated with the 'metabolic syndrome' is supported by clinical data as well as findings of elevated adipose tissue UCP expression. The role of UCPs in this syndrome therefore exemplifies the multifactorial nature of these antiretroviral therapy complications.

Evaluation of potential interactions between mycophenolic acid derivatives and proton pump inhibitors.

To evaluate the incidence of gastrointestinal (GI) complications in solid organ transplant (SOT) recipients, impact of the complications on transplant outcomes, and the potential interactions between mycophenolic acid (MPA) derivatives and proton pump inhibitors (PPIs). An unrestricted literature search (1980-January 2012) was performed with MEDLINE and EMBASE using the following key words: drug-drug interaction, enteric-coated mycophenolic acid, GI complications, mycophenolate mofetil, solid organ transplant, and proton pump inhibitor, including individual agents within the class. Abstracts from scientific meetings were also evaluated. Additionally, reference citations from identified publications were reviewed. Relevant English-language, original research articles and review articles were evaluated if they focused on any of the topics identified in the search or included substantial content addressing GI complications in SOT recipients or drug interactions. GI complications are frequent among SOT recipients, with some studies showing prevalence rates as high as 70%. Transplant outcomes among renal transplant recipients are significantly impacted by GI complications, especially in patients requiring immunosuppressant dosage reductions or premature discontinuation. To this end, PPI use among patients receiving transplants is common. Recent data demonstrate that PPIs significantly reduce the overall exposure to MPA after oral administration of mycophenolate mofetil. Similar studies show this interaction does not exist between PPIs and enteric-coated mycophenolic acid (EC-MPA). Unfortunately, most of the available data evaluating this interaction are pharmacokinetic analyses that do not investigate the clinical impact of this interaction. A significant interaction exists between PPIs and mycophenolate mofetil secondary to reduced dissolution of mycophenolate mofetil in higher pH environments. EC-MPA is not absorbed in the stomach; therefore, low intragastric acidity does not impact EC-MPA and bioavailability is maintained with this formulation during PPI coadministration. The clinical impact of this interaction is unknown, yet one can theorize that reduced exposure to MPA in SOT recipients can increase the risk of allograft rejection and/or failure.

Cardiac Arrest during Hospitalization for Delivery in the United States, 1998–2011

PubMed Central

Mhyre, Jill M.; Tsen, Lawrence C.; Einav, Sharon; Kuklina, Elena V.; Leffert, Lisa R.; Bateman, Brian T.

Background The objective of this analysis was to evaluate the frequency, distribution of potential etiologies, and survival rates of maternal cardiopulmonary arrest during the hospitalization for delivery in the United States. Methods By using data from the Nationwide Inpatient Sample during the years 1998 through 2011, the authors obtained weighted estimates of the number of U.S. hospitalizations for delivery complicated by maternal cardiac arrest. Clinical and demographic risk factors, potential etiologies, and outcomes were identified and compared in women with and without cardiac arrest. The authors tested for temporal trends in the occurrence and survival associated with maternal arrest. Results Cardiac arrest complicated 1 in 12,000 or 8.5 per 100,000 hospitalizations for delivery (99% CI, 7.7 to 9.3 per 100,000). The most common potential etiologies of arrest included hemorrhage, heart failure, amniotic fluid embolism, and sepsis. Among patients with cardiac arrest, 58.9% of patients (99% CI, 54.8 to 63.0%) survived to hospital discharge. Conclusions Approximately 1 in 12,000 hospitalizations for delivery is complicated by cardiac arrest, most frequently due to hemorrhage, heart failure, amniotic fluid embolism, or sepsis. Survival depends on the underlying etiology of arrest. PMID:24694844

Background: Leukaemic patients receiving intensive chemotherapy and patients undergoing autologous stem-cell transplantation (ASCT) are routinely screened for oral foci of infection to reduce infectious complications that could occur during therapy. In this prospective study we assessed the effect of leaving chronic oral foci of infection untreated on the development of infectious complications in intensively treated haematological patients. Methods: We included and prospectively evaluated all intensively treated leukaemic patients and patients undergoing ASCT who were referred to our medical centre between September 2012 and May 2014, and who matched the inclusion/exclusion criteria. Acute oral foci of infection were removed before chemotherapy or ASCT, whereas chronic oral foci were left untreated. Results: In total 28 leukaemic and 35 ASCT patients were included. Acute oral foci of infection were found in 2 leukaemic (7%) and 2 ASCT patients (6%), and chronic oral foci of infection in 24 leukaemic (86%) and 22 ASCT patients (63%). Positive blood cultures with microorganisms potentially originating from the oral cavity occurred in 7 patients during treatment, but were uneventful on development of infectious complications. Conclusions: Our prospective study supports the hypothesis that chronic oral foci of infection can be left untreated as this does not increase infectious complications during intensive chemotherapy.

Lovrenski, Jovan

2012-03-01

To evaluate the diagnostic possibilities of lung ultrasonography (LUS) in detecting pulmonary complications in preterm infants with respiratory distress syndrome (RDS). A prospective study included 120 preterm infants with clinical and radiographic signs of RDS. LUS was performed using both a transthoracic and a transabdominal approach within the first 24 h of life, and, after that, follow-up LUS examinations were performed. In 47 detected pulmonary complications of RDS (hemorrhage, pneumothorax, pneumonia, atelectasis, bronchopulmonary dysplasia), comparisons between LUS and chest X-ray (CXR) were made. Also, 90 subpleural consolidations registered during LUS examinations were analysed. Statistical analysis included MANOVA and discriminant analysis, t-test, confidence interval, and positive predictive value. In 45 of 47 instances the same diagnosis of complication was detected with LUS as with CXR, indicating a high reliability of the method in premature infants with RDS. The only two false negative findings concerned partial pneumothorax. The positive predictive value of LUS was 100%. A statistically significant difference of LUS findings between the anterior and posterior lung areas was observed in both right and left hemithoraces. LUS enables the detection of pulmonary complications in preterm infants with RDS and has the potential to reduce the number of CXRs. The specific guidelines for its use should be provided in a more extensive study.

Thyroid Swelling and Thyroiditis in the Setting of Recent hCG Injections and Fine Needle Aspiration

Lamos, Elizabeth M.; Munir, Kashif M.

2016-01-01

A 60-year-old woman presented with a neck mass and underwent fine needle aspiration of a left thyroid nodule. During this time, she had been injected with hCG for weight loss. Soon after, she developed rapid diffuse thyroid growth with pain. She was ultimately diagnosed with thyrotoxicosis due to postaspiration subacute thyroiditis and subsequently became hypothyroid. This condition is rare in the nonpregnant state in noncystic nodules with a smaller needle gauge approach. The incidence of thyroid nodule discovery and evaluation is increasing. As more procedures are undertaken, understanding of potential complications is important. This case highlights potential complications of thyroid fine needle aspiration including diffuse thyroid swelling and thyroiditis. The role of hCG injections is speculated to have potentially stimulated thyroid follicular epithelium via cross-reactivity with the TSH receptor and contributed to the acute inflammatory response after fine needle aspiration.

Pharmacogenetics of leptin in antipsychotic-associated weight gain and obesity-related complications

PubMed Central

Lee, Amy K; Bishop, Jefrey R

2013-01-01

Second-generation antipsychotics can greatly improve symptoms of psychosis-spectrum disorders. Unfortunately, these drugs are associated with weight gain, which increases a patient’s risk for developing chronic diseases including Type 2 diabetes, cardiovascular diseases or other obesity-related complications. There are interindividual differences in weight gain resulting from antipsychotic drug use that may be explained by pharmacodynamic characteristics of these agents as well as clinical factors. In addition, genetic variations in pathways associated with satiety are increasingly recognized as potential contributors to antipsychotic-associated weight gain. Polymorphisms in the leptin gene, as well as the leptin receptor gene, are potential pharmacogenetic markers associated with these outcomes. This article summarizes evidence for the associations of the leptin gene and the leptin receptor gene polymorphisms with antipsychotic-induced weight gain, potential mechanisms underlying these relationships, and discusses areas for future pharmacogenetic investigation.

2015-01-01

Percutaneous Coronary Intervention (PCI) of Chronic Total Occlusions (CTO) is an accepted revascularization procedure. These complex procedures carry with them certain risks and potential complications. Complications of PCI such as contrast induced renal dysfunction, radiation, etc, assume more relevance given the length and complexity of these procedures. Further, certain complications such as donor vessel injury, foreign body entrapment are unique to CTO PCI. A thorough understanding of the potential complications is important in mitigating risk during these complex procedures.

Surgical outcomes are determined by complex interactions among a variety of factors including patient characteristics, diagnosis, and type of procedure. The aim of this study was to prioritize the effect and relative importance of the surgeon (in terms of identity of a surgeon and surgeon volume), patient characteristics, and the intraoperative details on complications of colorectal surgery including readmission, reoperation, sepsis, anastomotic leak, small-bowel obstruction, surgical site infection, abscess, need for transfusion, and portal and deep vein thrombosis. This study uses a novel classification methodology to measure the influence of various risk factors on postoperative complications in a large outcomes database. Using prospectively collected information from the departmental outcomes database from 2010 to 2011, we examined the records of 3552 patients who underwent colorectal surgery. Instead of traditional statistical methods, we used a family of 7000 bootstrap classification models to examine and quantify the impact of various factors on the most common serious surgical complications. For each complication, an ensemble of multivariate classification models was designed to determine the relative importance of potential factors that may influence outcomes of surgery. This is a new technique for analyzing outcomes data that produces more accurate results and a more reliable ranking of study variables in order of their importance in producing complications. Patients who underwent colorectal surgery in 2010 and 2011 were included. This study was conducted at a tertiary referral department at a major medical center. Postoperative complications were the primary outcomes measured. Factors sorted themselves into 2 groups: a highly important group (operative time, BMI, age, identity of the surgeon, type of surgery) and a group of low importance (sex, comorbidity, laparoscopy, and emergency). ASA score and diagnosis were of intermediate importance. The outcomes most influenced by variations in the highly important factors included readmission, transfusion, surgical site infection, and abscesses. This study was limited by the use of data from a single tertiary referral department at a major medical center. Body mass index, operative time, and the surgeon who performed the operation are the 3 most important factors influencing readmission rates, rates of transfusions, and surgical site infection. Identification of these contributing factors can help minimize complications.

Complicated grief after perinatal loss

PubMed Central

Kersting, Anette; Wagner, Birgit

2012-01-01

The loss of an infant through stillbirth, miscarriage, or neonatal death is recognized as a traumatic life event. Predictors of development of complicated grief after prenatal loss include lack of social support, pre-existing relationship difficulties, or absence of surviving children, as well as ambivalent attitudes or heightened perception of the reality of the pregnancy. Risk of complicated grief was found to be especially high after termination of a pregnancy due to fetal abnormality. Studies have revealed that men and women show different patterns of grief, potentially exacerbating decline in a relationship. Although it is clear that prenatal loss has a large psychological impact, it is concluded that there is a substantial lack of randomized controlled studies in this field of research, PMID:22754291

Biventricular correction of tetralogy of Fallot was devised more than 50 years ago. Current short-term outcomes are excellent. The potential for late complications is, however, an important concern for the growing number of postrepair survivors. Progressive pulmonary valve regurgitation leading to right heart failure and arrhythmia are centrally important problems faced by these patients. New techniques are, however, likely to change the future outcomes for postrepair survivors. These techniques include percutaneous valve replacement, arrhythmia ablation surgery, and strategies that emphasize preservation of the pulmonary valve even at the cost of leaving some residual valvular stenosis. The objectives of this Review are to outline the major complications that arise late after repair of tetralogy of Fallot, to describe the surgical approaches that have been developed to avoid and manage arising complications, and to briefly explore how novel treatment paradigms could change the future long-term outlook for patients following tetralogy repair.

The effect of hospital organizational characteristics on postoperative complications.

To determine if there is a relationship between the risk of postoperative complications and the nonclinical hospital characteristics of bed size, ownership structure, relative urbanicity, regional location, teaching status, and area income status. This study involved a secondary analysis of 2006 administrative hospital data from a number of U.S. states. This data, gathered annually by the Agency for Healthcare Research and Quality (AHRQ) via the National Inpatient Sample (NIS) Healthcare Utilization Project (HCUP), was analyzed using probit regressions to measure the effects of several nonclinical hospital categories on seven diagnostic groupings. The study model included postoperative complications as well as additional potentially confounding variables. The results showed mixed outcomes for each of the hospital characteristic groupings. Subdividing these groupings to correspond with the HCUP data analysis allowed a greater understanding of how hospital characteristics' may affect postoperative outcomes. Nonclinical hospital characteristics do affect the various postoperative complications, but they do so inconsistently.

Type 2 Diabetes (T2D) is a chronic disease associated with a number of micro- and macrovascular complications that increase the morbidity and mortality of patients. The risk of diabetic complications has a strong genetic component. To this end, we sought to evaluate the association of 40 single nucleotide polymorphisms (SNPs) in 21 candidate genes with T2D and its vascular complications in 503 T2D patients and 580 healthy controls. The genes were chosen because previously reported to be associated with T2D complications and/or with the aging process. We replicated the association of T2D risk with I GF2BP rs4402960 and detected novel associations with TERT rs2735940 and rs2736098. The addition of these SNPs to a model including traditional risk factors slightly improved risk prediction. After stratification of patients according to the presence/absence of vascular complications, we found significant associations of variants in the CAT , FTO , and UCP1 genes with diabetic retinopathy and nephropathy. Additionally, a variant in the ADIPOQ gene was found associated with macrovascular complications. Notably, these genes are involved in some way in mitochondrial biology and reactive oxygen species regulation. Hence, our findings strongly suggest a potential link between mitochondrial oxidative homeostasis and individual predisposition to diabetic vascular complications.

Maternal trait personality and childbirth: the role of extraversion and neuroticism.

Johnston, R G; Brown, A E

2013-11-01

anxiety during pregnancy and childbirth can increase risk of complications and interventions for both mother and infant. Although considerable work has explored fear of childbirth and anxiety during labour and subsequent birth outcomes there has been less consideration of the role of more stable maternal personality upon childbirth. Traits of neuroticism and extraversion are however predictive of health outcomes in other fields potentially through biological, psychological and social mechanisms. The aim of the current research was thus to examine the relationship between trait personality and childbirth experience. seven hundred and fifty-five mothers with an infant aged 0-6 months completed a self-report questionnaire including the Ten Item Personality Measure and descriptions of birth experience including mode of birth [vaginal vs. caesarean section] and complications [failure to progress, fetal distress, post-partum haemorrhage, assisted birth and severe tear]. personality traits were significantly associated with birth experience. Specifically mothers scoring low in extraversion and emotional stability were significantly more likely to have a caesarean section and experience a number of complications during labour and birth including an assisted birth, fetal distress, failure to progress and a severe tear. Findings were independent of maternal age, education and parity. the personality traits of extraversion and emotional stability appear to facilitate likelihood of normal birth. Potential explanations for this include biological (physiological reactivity, pain thresholds, oxytocin and dopamine release) and psychological (coping mechanisms, social support, self-efficacy) factors. The findings have important implications for antenatal education and support during labour. Copyright © 2012 Elsevier Ltd. All rights reserved.

Cardiovascular Collapse During Transcatheter Aortic Valve Replacement: Diagnosis and Treatment of the “Perilous Pentad”

PubMed Central

El-Gamel, Adam

2013-01-01

Transcatheter aortic valve replacement (TAVR) has, without a doubt, brought an unprecedented excitement to the field of interventional cardiology. The avoidance of a sternotomy by transfemoral or transapical aortic-valve implantation appears to come at the price of some serious complications, including an increased risk of embolic stroke and paravalvular leakage. The technical challenges of the procedure and the complex nature of the high-risk patient cohort make the learning curve for this procedure a steep one, with the potential for unexpected complications always looming. Although most commonly relating to vascular access, these complications can also result from prosthesis-related trauma or malposition, or from unanticipated trauma from the pacing wire or the super stiff wire. Sudden and unexplained hypotension is often the earliest indicator of major complication and must prompt an immediate and detailed exclusion of five major pathologies: retroperitoneal bleeding from access site rupture, aortic dissection or rupture, pericardial tamponade, coronary ostial obstruction, or acute severe aortic regurgitation. In most cases, these can be dealt with quickly, and by percutaneous means, although open surgery may occasionally be necessary. Increased operator and team experience should make prevention and recognition of these catastrophic complications more complete. For this reason, the importance of specific training, such as that provided by the valve manufacturers through workshops and proctorship, cannot be overemphasized. It is essential that all operators, and indeed all members of the implant team, exert extreme vigilance to the development of intraprocedural complications, which could have rapid and potentially lethal consequences. Greater experience with an improved understanding of these risks, along with the development of better devices, deliverable through smaller and less traumatic sheath technology, will undoubtedly improve the safety and, potentially, widen the applicability of TAVR in the future. Forthcoming innovations include a newer generation of the valves with operator-controlled steerability to facilitate negotiation of tortuous aortic anatomy, as well as fully retrievable and resheathable devices to accommodate the events of dislocation or embolization. The fact that Transcatheter aortic valve implantation (TAVI) is new implies learning from experience but also from mistakes. The TAVI team must be vigilant to recognize and diagnose intraprocedure severe hypotension. The “perilous pentad” of catastrophic causes must be constantly borne in mind: retroperitoneal bleeding from access site rupture, aortic dissection or rupture, pericardial tamponade, coronary ostial obstruction, and acute severe aortic insufficiency.

PurposeTo report hepatic arterial-related complications encountered during planning and treatment angiograms for radioembolization and understand any potential-associated risk factors.Materials and Methods518 mapping or treatment angiograms for 180 patients with primary or metastatic disease to the liver treated by Yttrium-90 radioembolization between 2/2010 and 12/2015 were retrospectively reviewed. Intra-procedural complications were recorded per SIR guidelines. Patient demographics, indication for treatment, prior exposure to chemotherapeutic agents, operator experience, and disease burden were reviewed. Technical variables including type of radioembolic (glass vs. resin microspheres), indication for angiography (mapping vs. treatment), variant anatomy, and attempts at coil embolization were also assessed.ResultsThirteen (13/518, 2.5%) arterial-relatedmore » complications occurred in 13 patients. All but two complications resulted during transcatheter coil embolization to prevent non-target embolization. Complications included coil migration (n = 6), arterial dissection (n = 2), focal vessel perforation (n = 2), arterial thrombus (n = 2), and vasospasm prohibiting further arterial sub-selection (n = 1). Transarterial coiling was identified as a significant risk factor of complications on both univariate and multivariate regression analysis (odds ratio 7.8, P = 0.004). Usage of resin microspheres was also a significant risk factor (odds ratio 9.5, P = 0.042). No other technical parameters or pre-procedural variables were significant after adjusting for confounding on multivariate analysis (P > 0.05).ConclusionIntra-procedural hepatic arterial complications encountered during radioembolization were infrequent but occurred mainly during coil embolization to prevent non-target delivery to extra-hepatic arteries.« less

In clinical practice of rheumatoid arthritis (RA), various kinds of laboratory tests are required for diagnosis, assessment of the disease activity, assessment of complications and risk factors before starting therapy, and assessment of adverse effects during the therapy. Anemia, thrombocytosis, and leukocytosis are common in active RA. During RA therapies, liver function tests (including ALT and AST) and renal function tests (including serum creatinine and urinalysis) should be performed. Anti-CCP antibody is an especially useful marker for diagnosis of RA, and the presence of the antibody has been included in ACR/EULAR 2010 RA classification criteria. Reactivation of hepatitis B virus (HBV) after immunosuppressive therapies is a potentially serious complication. HBc and/or HBs antibodies should be measured before starting the therapies even if HBs antigen is negative, and appropriate interventions including measurement of HBV-DNA and starting prophylaxis (entecavir is recommended) should be performed.

OBJECTIVE To evaluate potential associations between surgical approach and complication rate, progression-free survival time, and disease-specific survival time in cats with mammary adenocarcinoma. DESIGN Retrospective case series. ANIMALS 107 client-owned cats. PROCEDURES Medical records of cats that underwent surgical excision of mammary adenocarcinoma by means of a unilateral or bilateral (staged or single-session) mastectomy at 9 hospitals between 1991 and 2014 were reviewed. Relevant clinicopathologic data and details of surgical and adjuvant treatments were recorded. Outcome data were obtained, including postoperative complications, progression-free survival time, and disease-specific survival time. RESULTS Complications occurred in 12 of 61 (19.7%) cats treated with unilateral mastectomy, 5 of 14 (35.7%) cats treated with staged bilateral mastectomy, and 13 of 32 (40.6%) cats treated with single-session bilateral mastectomy. Complications were significantly more likely to occur in cats undergoing bilateral versus unilateral mastectomy. Median progression-free survival time was longer for cats treated with bilateral mastectomy (542 days) than for cats treated with unilateral mastectomy (289 days). Significant risk factors for disease progression included unilateral mastectomy, tumor ulceration, lymph node metastasis, and tumors arising in the fourth mammary gland. Significant risk factors for disease-specific death included lymph node metastasis and development of regional or distant metastasis. Among cats that did not develop metastasis, unilateral mastectomy was a significant risk factor for disease-specific death. Treatment with chemotherapy was associated with a significantly decreased risk of disease-specific death. CONCLUSIONS AND CLINICAL RELEVANCE Results supported bilateral mastectomy for the treatment of mammary adenocarcinoma in cats to improve progression-free and disease-specific survival time. Performing bilateral mastectomy in a staged fashion may help to decrease the complication rate.

Fundamentals of pain management in wound care.

PubMed

Coulling, Sarah

Under-treated pain can result in a number of potentially serious sequelae (Australian and New Zealand College of Anaesthetists, 2006), including delayed mobilization and recovery, cardiac complications, thromboses, pulmonary complications, delayed healing, psychosocial problems and chronic pain syndromes. This article considers pain management in the context of painful wounds. An international comparative survey on wound pain (European Wound Management Association, 2002) found that practitioners in the wound care community tend to focus on healing processes rather than the patient's total pain experience involving an accurate pain assessment and selection of an appropriate pain management strategy. Procedural pain with dressing removal and cleansing caused the greatest concerns. An overview of simple, evidence-based drug and non-drug techniques is offered as potential strategies to help minimize the experience of pain.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is potentially a curative therapeutic option for hematological malignancies. In clinical practice, transplantation associated complications greatly affected the final therapeutical outcomes. Currently, primary disease relapse, graft-versus-host disease (GVHD) and infections remain the three leading causes of a high morbidity and mortality in allo-HSCT patients. Various strategies have been investigated in the past several decades including human γδ T cell-based therapeutical regimens. In different microenvironments, human γδ T cells assume features reminiscent of classical Th1, Th2, Th17, NKT and regulatory T cells, showing diverse biological functions. The cytotoxic γδ T cells could be utilized to target relapsed malignancies, and recently regulatory γδ T cells are defined as a novel implement for GVHD management. In addition, human γδ Τ cells facilitate control of post-transplantation infections and participate in tissue regeneration and wound healing processes. These features potentiate γδ T cells a versatile therapeutical agent to target transplantation associated complications. This review focuses on insights of applicable potentials of human γδ T cells reconciling complications associated with allo-HSCT. We believe an improved understanding of pertinent γδ T cell functions would be further exploited in the design of innovative immunotherapeutic approaches in allo-HSCT, to reduce mortality and morbidity, as well as improve quality of life for patients after transplantation.

Limited-incision total hip arthroplasty (THA) preserves hip abductors, posterior capsule, and external rotators potentially diminishing dislocation risk. However, potential complications also exist, such as component malposition. Specific implants have been manufactured that enhance compatibility with this technique, while preserving metaphyseal bone; however, little data exists documenting early complications and component position. The purpose was to evaluate primary THA using a curved, bone-sparing stem inserted through the anterior approach with respect to component alignment and early complications. In a retrospective analysis of 108 cases, the surgical technique was outlined and the occurrence of intraoperative fractures, postoperative dislocations, infection, and limb length inequality was determined. Femoral stem and acetabular cup alignment was quantified using the initial postoperative radiographs. Patient follow-up averaged 12.9 (range 2 to 36) months. There were eight (7.4 %) complications requiring revision surgery in three (2.8 %) patients with three (2.8 %) infections and three (2.8 %) dislocations. Intraoperative complications included one calcar fracture above the lesser trochanter. Leg length inequality >5 mm was present in three (2.8 %) patients. Radiographic analysis showed that femoral neutral alignment was achieved in 95 hips (88.0 %). All femoral stems demonstrated satisfactory fit and fill and no evidence of subsidence, osteolysis, or loosening. An average abduction angle of 44.8° (± 5.3) and average cup anteversion of 16.2° (± 4.2) were also noted. Although the technique with this implant and approach is promising, it does not appear to offer important advantages over standard techniques. However, the findings merit further, long-term study.

The recognition of the importance of diabetes in vascular disease has greatly increased lately. Common risk factors for diabetes-related vascular disease include hyperglycemia, insulin resistance, dyslipidemia, inflammation, hypercoagulability, hypertension, and atherosclerosis. All of these factors contribute to the endothelial dysfunction which generates the diabetic complications, both macro and microvascular. Knowledge of diabetes-related vascular complications and of associated mechanisms it is becoming increasingly important for therapists. The discovery of microparticles (MPs) and their associated microRNAs (miRNAs) have opened new perspectives capturing the attention of basic and clinical scientists for their potential to become new therapeutic targets and clinical biomarkers. MPs known as submicron vesicles generated from membranes of apoptotic or activated cells into circulation have the ability to act as autocrine and paracrine effectors in cell-to-cell communication. They operate as biological vectors modulating the endothelial dysfunction, inflammation, coagulation, angiogenesis, thrombosis, subsequently contributing to the progression of macro and microvascular complications in diabetes. More recently, miRNAs have started to be actively investigated, leading to first exciting reports, which suggest their significant role in vascular physiology and disease. The contribution of MPs and also of their associated miRNAs to the development of vascular complications in diabetes was largely unexplored and undiscussed. In essence, with this review we bring light upon the understanding of impact diabetes has on vascular biology, and the significant role of MPs and MPs associated miRNAs as novel mediators, potential biomarkers and therapeutic targets in vascular complications in diabetes.

The Aboriginal and Torres Strait Islander community has an increased risk of developing chronic illnesses including diabetes. Among people with diabetes, foot complications are common and make a significant contribution to the morbidity and mortality associated with this disease. The aim of this review was to systematically evaluate the literature comparing the rates of diabetes related foot complications in Aboriginal and Torres Strait Islander Australians to non-Indigenous Australians. MEDLINE, EMBASE, The Cochrane Library; PUBMED and CINAHL were searched from inception until August 2016. Inclusion criteria were: published cross-sectional or longitudinal studies reporting the prevalence of diabetes related foot complications in both a cohort of Aboriginal and Torres Strait Islander Australians and a cohort of one other Australian population of any age with diabetes. Risk of bias was assessed using the STROBE tool. Eleven studies including a total of 157,892 participants were included. Studies were set in Queensland, the Northern Territory and Western Australia, primarily in rural and remote areas. Aboriginal and Torres Strait Islander Australians experienced substantially more diabetes related foot complications with the mean age up to 14 years younger than non-Indigenous Australians. Aboriginality was associated with increased risk of peripheral neuropathy, foot ulceration and amputation. In several studies, Aboriginal and Torres Strait Islander Australians accounted for the vast majority of diabetes related foot complications (up to 91%) while comprising only a small proportion of the regional population. Reporting quality as assessed with the STROBE tool showed underreporting of: methods, sample description and potential sources of bias. There are no data available for some Australian states and for specific types of diabetes related foot complications. Aboriginal and Torres Strait Islander Australians have a 3-6 fold increased likelihood of experiencing a diabetes related foot complication compared to non-Indigenous Australians. Evidence-based, culturally appropriate screening and intervention programs and improved access to effective health care services are required to prevent a widening of the gap in diabetes related foot complications between Aboriginal and Torres Strait Islander and non-Indigenous Australians.

Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia, and is now one of the most non-communicable diseases globally and can be lethal if not properly controlled. Prolonged exposure to chronic hyperglycemia, without proper management, can lead to various vascular complications and represents the main cause of morbidity and mortality in diabetes patients. Studies have indicated that major long-term complications of diabetes arise from persistent oxidative-nitrosative stress and dysregulation in multiple metabolic pathways. Presently, the main focus for diabetes management is to optimize the available techniques to ensure adequate blood sugar level, blood pressure and lipid profile, thereby minimizing the diabetes complications. In this regard, nanomedicine utilizing gold nanostructures has great potential and seems to be a promising option. The present review highlights the basic concepts and up-to-date literature survey of gold nanostructure materials in management of diabetes in several ways, which include sensing, imaging, drug delivery and therapy. The work can be of interest to various researchers working on basic and applied sciences including nanosciences.

Review article: potential mechanisms of action of rifaximin in the management of hepatic encephalopathy and other complications of cirrhosis.

Progressive gut milieu (microbiota) changes occur in patients with cirrhosis and are associated with complications [e.g. hepatic encephalopathy (HE)]. To examine the role of rifaximin in the management of HE and other complications of cirrhosis, including potential mechanisms of action and the need for future studies. A literature search was conducted using the keywords 'rifaximin', 'hepatic encephalopathy', 'ascites', 'variceal bleeding', 'peritonitis', 'portal hypertension', 'portopulmonary hypertension' and 'hepatorenal syndrome'. The nonsystemic agent rifaximin reduces the risk of HE recurrence and HE-related hospitalisations in cirrhosis. In patients with cirrhosis, rifaximin modulates the bacterial composition of the gut microbiota without a consistent effect on overall faecal microbiota composition. However, rifaximin can impact the function or activities of the gut microbiota. For example, rifaximin significantly increased serum levels of long-chain fatty acids and carbohydrate metabolism intermediates in patients with minimal HE. Rifaximin also favourably affects serum proinflammatory cytokine and faecal secondary bile acid levels. The gut microenvironment and associated microbiota play an important role in the pathogenesis of HE and other cirrhosis-related complications. Rifaximin's clinical activity may be attributed to effects on metabolic function of the gut microbiota, rather than a change in the relative bacterial abundance. © 2015 John Wiley & Sons Ltd.

Perioperative goal-directed therapy (PGDT) has been demonstrated to improve postoperative outcomes and reduce the length of hospital stays. The objective of our analysis was to evaluate the cost of complications, derived from French hospital payments, and calculate the potential cost savings and length of hospital stay reductions. The billing of 2388 patients who underwent scheduled high-risk surgery (i.e. major abdominal, gynaecologic, urological, vascular, and orthopaedic interventions) over three years was retrospectively collected from three French hospitals (one public-teaching, one public, and one private hospital). A relationship between mortality, length of hospital stays, cost/patient, and severity scores, based mainly on postoperative complications but also on preoperative clinical status, were analysed. Statistical analysis was performed using Student's t-tests or Wilcoxon tests. Our analyses determined that a severity score of 3 or 4 was associated with complications in 90% of cases and this represented 36% of patients who, compared with those with a score of 1 or 2, were associated with significantly increased costs (€ 8205±3335 to € 22,081±16,090; P<0.001, delta of € 13,876) and a prolonged length of hospital stay (mean of 10 to 27 days; P<0.001, delta of 17 days). According to estimates for complications avoided by PGDT, there was a projected reduction in average healthcare costs of between € 854 and € 1458 per patient and a reduction in total hospital bed days from 1755 to 4423 over three years. Based on French National data (47,000 high risk surgeries per year), the potential financial savings ranged from € 40M to € 68M, not including the costs of PGDT and its implementation. Our analysis demonstrates that patients with complications are significantly more expensive to care for than those without complications. In our model, it was projected that implementing PGDT during high-risk surgery may significantly reduce healthcare costs and the length of hospital stays in France while probably improving patient access to care and reducing waiting times for procedures.

Bone loss of vertebral bodies at the operative segment after cervical arthroplasty: a potential complication?

PubMed

Heo, Dong Hwa; Lee, Dong Chan; Oh, Jong Yang; Park, Choon Keun

2017-02-01

OBJECTIVE Bony overgrowth and spontaneous fusion are complications of cervical arthroplasty. In contrast, bone loss or bone remodeling of vertebral bodies at the operation segment after cervical arthroplasty has also been observed. The purpose of this study is to investigate a potential complication-bone loss of the anterior portion of the vertebral bodies at the surgically treated segment after cervical total disc replacement (TDR)-and discuss the clinical significance. METHODS All enrolled patients underwent follow-up for more than 24 months after cervical arthroplasty using the Baguera C disc. Clinical evaluations included recording demographic data and measuring the visual analog scale and Neck Disability Index scores. Radiographic evaluations included measurements of the functional spinal unit's range of motion and changes such as bone loss and bone remodeling. The grading of the bone loss of the operative segment was classified as follows: Grade 1, disappearance of the anterior osteophyte or small minor bone loss; Grade 2, bone loss of the anterior portion of the vertebral bodies at the operation segment without exposure of the artificial disc; or Grade 3, significant bone loss with exposure of the anterior portion of the artificial disc. RESULTS Forty-eight patients were enrolled in this study. Among them, bone loss developed in 29 patients (Grade 1 in 15 patients, Grade 2 in 6 patients, and Grade 3 in 8 patients). Grade 3 bone loss was significantly associated with postoperative neck pain (p < 0.05). Bone loss was related to the motion preservation effect of the operative segment after cervical arthroplasty in contrast to heterotopic ossification. CONCLUSIONS Bone loss may be a potential complication of cervical TDR and affect early postoperative neck pain. However, it did not affect mid- to long-term clinical outcomes or prosthetic failure at the last follow-up. Also, this phenomenon may result in the motion preservation effect in the operative segment after cervical TDR.

To describe real-world treatment patterns and health care resource use and to estimate opportunities for early-switch (ES) from intravenous (IV) to oral (PO) antibiotics and early-discharge (ED) for patients hospitalized in the United Arab Emirates (UAE) with methicillin-resistant Staphylococcus aureus (MRSA) complicated skin and soft tissue infections. This retrospective observational medical chart review study enrolled physicians from four UAE sites to collect data for 24 patients with documented MRSA complicated skin and soft tissue infections, hospitalized between July 2010 and June 2011, and discharged alive by July 2011. Data include clinical characteristics and outcomes, hospital length of stay (LOS), MRSA-targeted IV and PO antibiotic use, and ES and ED eligibility using literature-based and expert-validated criteria. Five included patients (20.8%) were switched from IV to PO antibiotics while being inpatients. Actual length of MRSA-active treatment was 10.8±7.0 days, with 9.8±6.6 days of IV therapy. Patients were hospitalized for a mean 13.9±9.3 days. The most frequent initial MRSA-active therapies used were vancomycin (37.5%), linezolid (16.7%), and clindamycin (16.7%). Eight patients were discharged with MRSA-active antibiotics, with linezolid prescribed most frequently (n=3; 37.5%). Fifteen patients (62.5%) met ES criteria and potentially could have discontinued IV therapy 8.3±6.0 days sooner, and eight (33.3%) met ED criteria and potentially could have been discharged 10.9±5.8 days earlier. While approximately one-fifth of patients were switched from IV to PO antibiotics in the UAE, there were clear opportunities for further optimization of health care resource use. Over half of UAE patients hospitalized for MRSA complicated skin and soft tissue infections could be eligible for ES, with one-third eligible for ED opportunities, resulting in substantial potential for reductions in IV days and bed days.

Transcatheter aortic valve replacement in patients with severe aortic stenosis who are at high risk for surgical complications: summary assessment of the California Technology Assessment Forum.

PubMed

Tice, Jeffrey A; Sellke, Frank W; Schaff, Hartzell V

2014-08-01

The California Technology Assessment Forum is dedicated to assessment and public reporting of syntheses of available data on medical technologies. In this assessment, transcatheter aortic valve replacement (TAVR) was evaluated for patients with severe aortic stenosis (AS) who are at high risk for complications. In this assessment, 5 criteria were used: Regulatory approval, sufficient scientific evidence to allow conclusions on effectiveness, evidence that the technology improves net health outcomes, evidence that the technology is as beneficial as established methods, and availability of the technology outside investigational settings. In this assessment, all 5 criteria were judged to have been met. The primary benefit of TAVR is the ability to treat AS in patients who would otherwise be ineligible for surgical aortic valve replacement. It may also be useful for patients at high surgical risk by potentially reducing periprocedural complications and avoiding the morbidity and recovery from undergoing heart surgery. Potential harms include the need for conversion to an open procedure, perioperative death, myocardial infarction, stroke, bleeding, valve embolization, aortic regurgitation, heart block that requires a permanent pacemaker, renal failure, pulmonary failure, and major vascular complications such as cardiac perforation or arterial dissection. Potential long-term harms include death, stroke, valve failure or clotting, and endocarditis. As highlighted at the February 2012 California Technology Assessment Forum meeting, the dispersion of this technology to new centers across the United States must proceed with careful thought given to training and proctoring multidisciplinary teams to become new centers of excellence. TAVR is a potentially lifesaving procedure that may improve quality of life for patients at high risk for surgical AVR. However, attention needs to be paid to appropriate patient selection, their preoperative evaluation, surgical techniques, and postoperative care to preserve and improve on the results attained in the Placement of Aortic Transcatheter Valve trial. Specialty societies are collaborating to ensure that this happens in a rational and comprehensive manner. Copyright © 2014 The American Association for Thoracic Surgery. Published by Mosby, Inc.

Vasquez, Jay

2011-01-01

Central venous lines have become an integral part of patient care, but they are not without complications. Vertebral artery pseudoaneurysm formation is one of the rarer complications of central line placement. Presented is a rare case of two pseudoaneurysms of the vertebral and subclavian artery after an attempted internal jugular vein catheterization. These were successfully treated with open surgical repair and bypass. Open surgical repair remains the gold standard of treatment. Endovascular repair of vertebral artery pseudoaneurysms has been described with promising outcomes, but long-term results are lacking. Ultimately, the best treatment of these iatrogenic injuries should start with prevention. Well-documented techniques to minimize mechanical complications, including inadvertent arterial puncture, should be practiced and taught in training programs to avoid the potentially devastating consequences.

Public tolerance to adverse reactions is minimal. Several reporting systems have been established to monitor adverse events following immunization. The present review summarizes data on neurologic complications following vaccination, and provides evidence that indicates whether they were directly associated with the vaccines. These complications include autism (measles vaccine), multiple sclerosis (hepatitis B vaccine), meningoencephalitis (Japanese encephalitis vaccine), Guillain-Barré syndrome and giant cell arteritis (influenza vaccine), and reactions after exposure to animal rabies vaccine. Seizures and hypotonic/hyporesponsive episodes following pertussis vaccination and potential risks associated with varicella vaccination, as well as vaccine-associated paralytic poliomyelitis following oral poliovirus vaccination, are also described. In addition, claims that complications are caused by adjuvants, preservatives and contaminants [i.e. macrophagic myofasciitis (aluminium), neurotoxicity (thimerosal), and new variant Creutzfeldt-Jakob disease (bovine-derived materials)] are discussed.

Anesthesia and sedation in pediatric gastrointestinal endoscopic procedures: A review

PubMed Central

Dar, Abdul Q; Shah, Zahoor A

2010-01-01

Gastrointestinal (GI) endoscopic procedure has become an essential modality for evaluation and treatment of GI diseases. Intravenous (IV) sedation and General Anesthesia (GA) have both been employed to minimize discomfort and provide amnesia. Both these procedures require, at the very least, monitoring of the level of consciousness, pulmonary ventilation, oxygenation and hemodynamics. Although GI endoscopy is considered safe, the procedure has a potential for complications. Increased awareness of the complications associated with sedation during GI endoscopy in children, and involving the anesthesiologists in caring for these children, may be optimal for safety. Belonging to a younger age group, having a higher ASA class and undergoing IV sedation were identified as risk factors for developing complications. Reported adverse events included inadequate sedation, low oxygen saturation, airway obstruction, apnea needing bag mask ventilation, excitement and agitation, hemorrhage and perforation. A complication rate of 1.2% was associated with procedures performed under GA, as compared to 3.7% of complications associated with IV sedation. IV sedation was seen to be independently associated with a cardiopulmonary complication rate 5.3% times higher when compared to GA. GA can therefore be considered safer and more effective in providing comfort and amnesia. PMID:21160616

Extracranial-to-intracranial (EC-IC) bypass surgery may be necessary in patients with moyamoya disease and other ischemic conditions. However, there is a potential risk of wound-related complications in some cases. In this study, we report our approach to prevention of wound-related complications in EC-IC bypass, and technical consideration and pitfalls of surgery are discussed. This study included 89 patients with ischemic-onset moyamoya disease and atherosclerotic disease, who underwent 108 superficial temporal artery (STA)-to-middle cerebral artery bypass procedures. Our study emphasized 3 major features. First, 3-dimensional simulation imaging was used to confirm STA anatomy. Second, the STA was meticulously dissected on the epigaleal layer, and protected the galeal layer. Third, scalp skin ischemia was taken into consideration at each step until skin closure. There was no neurological morbidity or mortality in this series. There were 2 cases with major wound-related complications that needed plastic surgical intervention, and 4 cases with minor complications that were treated conservatively. In major complication cases, the scalp defect was treated with pedicle flap reconstruction. In EC-IC bypass surgery, interdisciplinary management involving neurosurgery, plastic surgery, and radiology should reduce wound-related complications, and achieve safe surgery.

Impact of Diabetic Complications on Balance and Falls: Contribution of the Vestibular System

PubMed Central

Lin, James; Staecker, Hinrich; Whitney, Susan L.; Kluding, Patricia M.

2016-01-01

Diabetes causes many complications, including retinopathy and peripheral neuropathy, which are well understood as contributing to gait instability and falls. A less understood complication of diabetes is the effect on the vestibular system. The vestibular system contributes significantly to balance in static and dynamic conditions by providing spatially orienting information. It is noteworthy that diabetes has been reported to affect vestibular function in both animal and clinical studies. Pathophysiological changes in peripheral and central vestibular structures due to diabetes have been noted. Vestibular dysfunction is associated with impaired balance and a higher risk of falls. As the prevalence of diabetes increases, so does the potential for falls due to diabetic complications. The purpose of this perspective article is to present evidence on the pathophysiology of diabetes-related complications and their influence on balance and falls, with specific attention to emerging evidence of vestibular dysfunction due to diabetes. Understanding this relationship may be useful for screening (by physical therapists) for possible vestibular dysfunction in people with diabetes and for further developing and testing the efficacy of interventions to reduce falls in this population.

Women with spinal cord injury (SCI) and who develop breast cancer are a vulnerable and potentially overlooked population. They experience risk factors owing to decreased mobility and are at risk for unique complications from their oncologic treatment. A 54-year-old woman who suffered a T6 AIS A traumatic SCI in 1981, who was diagnosed 32 years later with estrogen receptor and progesterone receptor positive and human epidermal growth factor receptor 2-negative invasive ductal carcinoma. During the course of her chemotherapy, she experienced several complications, including reflexive diaphoresis, urinary tract infection, leukopenia, anemia, dehydration, and weakness. These contributed to the development of a stage 4 ischial pressure sore, which required complex treatment. There is a paucity of literature examining the complications of chemotherapy that may be unique to those with SCI. Physiatrists will be seeing more women undergoing oncologic care, as this population of patients ages. A multidisciplinary approach that takes into account the pathophysiologic changes associated with SCI is crucial to understand and prevent complications that could affect their outcomes and contribute to increased cost in a value-based health-care system.

A Systematic Review and Meta-Analysis on the Safety of Vascular Endothelial Growth Factor (VEGF) Inhibitors for the Treatment of Retinopathy of Prematurity

Introduction Laser photocoagulation is the current gold standard treatment for proliferative retinopathy of prematurity (ROP). However, it permanently reduces the visual field and might induce myopia. Vascular endothelial growth factor (VEGF) inhibitors for the treatment of ROP may enable continuing vascularization of the retina, potentially allowing the preservation of the visual field. However, for their use in infants concern remains. This meta-analysis explores the safety of VEGF inhibitors. Methods The Ovid Interface was used to perform a systematic review of the literature in the databases PubMed, EMBASE and the Cochrane Library. Results This meta-analysis included 24 original reports (including 1.457 eyes) on VEGF inhibitor treatment for ROP. The trials were solely observational except for one randomized and two case-control studies. We estimated a 6-month risk of retreatment per eye of 2.8%, and a 6-month risk of ocular complication without the need of retreatment of 1.6% per eye. Systemic complications were only reported as isolated incidents. Discussion VEGF inhibitors seem to be associated with low recurrence rates and ocular complication rates. They may have the benefit of potentially allowing the preservation of visual field and lower rates of myopia. Due to the lack of data, the risk of systemic side effects cannot be assessed.

Type 2 diabetes mellitus (T2DM) is no more a lifestyle disease of developed countries. It has emerged as a major health problem worldwide including developing countries. However, how diabetes could be detected at an early stage (prediabetes) to prevent the progression of disease is still unclear. Currently used biomarkers like glycated hemoglobin and assessment of blood glucose level have their own limitations. These classical markers can be detected when the disease is already established. Prognosis of disease at early stages and prediction of population at a higher risk require identification of specific markers that are sensitive enough to be detected at early stages of disease. Biomarkers which could predict the risk of disease in people will be useful for developing preventive/proactive therapies to those individuals who are at a higher risk of developing the disease. Recent studies suggested that the expression of biomolecules including microRNAs, proteins, and metabolites specifically change during the progression of T2DM and related complications, suggestive of disease pathology. Owing to their omnipresence in body fluids and their association with onset, progression, and pathogenesis of T2DM, these biomolecules can be potential biomarker for prognosis, diagnosis, and management of disease. In this article, we summarize biomolecules that could be potential biomarkers and their signature changes associated with T2DM and related complications during disease pathogenesis. PMID:29740397

Central venous catheters: legal issues.

Gallieni, Maurizio; Martina, Valentina; Rizzo, Maria Antonietta; Gravellone, Luciana; Mobilia, Francesca; Giordano, Antonino; Cusi, Daniele; Genovese, Umberto

2011-01-01

In dialysis patients, both central venous catheter (CVC) insertion and CVC use during the dialysis procedure pose important legal issues, because of potentially severe, even fatal, complications. The first issue is the decision of the kind of vascular access that should be proposed to patients: an arteriovenous (AV) fistula, a graft, or a CVC. The second issue, when choosing the CVC option, is the choice of CVC: nontunneled versus tunneled. Leaving a temporary nontunneled CVC for a prolonged time increases the risk of complications and could raise a liability issue. Even when choosing a long-term tunneled CVC, nephrologists should systematically explain its potential harms, presenting them as "unsafe for long-term use" unless there is a clear contraindication to an AV native or prosthetic access. Another critical issue is the preparation of a complete, informative, and easy-to-understand consent form. The CVC insertion procedure has many aspects of legal interest, including the choice of CVC, the use of ECG monitoring, the use of ultrasound guidance for cannulation, and the use of fluoroscopy for checking the position of the metal guidewire during the procedure as well as the CVC tip before the end of the procedure. Use of insertion devices and techniques that can prevent complications should obviously be encouraged. Complications of CVC use are mainly thrombosis and infection. These are theoretically expected as pure complications (and not as malpractice effects), but legal issues might relate to inappropriate catheter care (in both the inpatient and outpatient settings) rather than to the event per se. Thus, in the individual case it is indeed very difficult to establish malpractice and liability with a catheter-related infection or thrombosis. In conclusion, we cannot avoid complications completely when using CVCs, but reducing them to a minimum and adopting safe approaches to their insertion and use will reduce legal liability.

Acute fatal metabolic complications in alkaptonuria.

PubMed

Davison, A S; Milan, A M; Gallagher, J A; Ranganath, L R

2016-03-01

Alkaptonuria (AKU) is a rare inherited metabolic disorder of tyrosine metabolism that results from a defect in an enzyme called homogentisate 1,2-dioxygenase. The result of this is that homogentisic acid (HGA) accumulates in the body. HGA is central to the pathophysiology of this disease and the consequences observed; these include spondyloarthropathy, rupture of ligaments/muscle/tendons, valvular heart disease including aortic stenosis and renal stones. While AKU is considered to be a chronic progressive disorder, it is clear from published case reports that fatal acute metabolic complications can also occur. These include oxidative haemolysis and methaemoglobinaemia. The exact mechanisms underlying the latter are not clear, but it is proposed that disordered metabolism within the red blood cell is responsible for favouring a pro-oxidant environment that leads to the life threatening complications observed. Herein the role of red blood cell in maintaining the redox state of the body is reviewed in the context of AKU. In addition previously reported therapeutic strategies are discussed, specifically with respect to why reported treatments had little therapeutic effect. The potential use of nitisinone for the management of patients suffering from the acute metabolic decompensation in AKU is proposed as an alternative strategy.

By applying a Pekeris-type approximation to the pseudo-centrifugal term, we study the pseudospin symmetry of a Dirac nucleon subjected to scalar and vector modified Rosen-Morse (MRM) potentials. A complicated quartic energy equation and spinor wave functions with arbitrary spin-orbit coupling quantum number k are presented. The pseudospin degeneracy is checked numerically. Pseudospin symmetry is discussed theoretically and numerically in the limit case α rightarrow 0 . It is found that the relativistic MRM potential cannot trap a Dirac nucleon in this limit.

2015-12-01

Complications related to inflatable penile prosthesis (IPP) and artificial urinary sphincter (AUS) reservoirs are rare, potentially life threatening, and poorly described in the literature. As more devices are implanted, the incidence of reservoir-related complications may increase, and it will be important to recognize the relevant signs and symptoms. We present a case series of reservoir-related complications presenting to our institution for treatment. We also reviewed all accounts of reservoir-related complications within the urologic literature. Three cases of reservoir-related complications are presented. Case 1 involves erosion of an intact AUS reservoir into the cecum of a patient with a history of myelomeningocele and bladder augmentation. Case 2 involves an IPP reservoir causing vascular compression, resulting in open exploration and repositioning of the reservoir. Case 3 involves intraperitoneal migration of a retained IPP reservoir to a subhepatic area, which was then removed laparoscopically. Literature review yielded descriptions of eight cases of intestinal complications, five cases of vascular complications, but zero reports of migration to a subhepatic area. Other notable complications include 20 reported cases of reservoir erosion into the bladder and inguinal herniation of the reservoir. Complications involving urologic prosthesis reservoirs, although rare, can have serious implications for patients. A high index of suspicion and familiarity with treatment options is required in order to allow timely diagnosis and appropriate treatment. Patients with prior major abdominal surgeries seem to be more prone to intestinal complications of reservoirs and warrant special concern. Cui T, Terlecki R, and Mirzazadeh M.

2003-01-01

WE REPORT A CASE INVOLVING AN 81-YEAR-OLD man with schizoaffective disorder who presented with neuroleptic malignant syndrome (NMS) after an increase in his neuroleptic dose. NMS, a rare but potentially fatal complication of neuroleptic medications (e.g., antipsychotics, sedatives and antinauseants), is characterized by hyperthermia, muscle rigidity, an elevated creatine kinase level and autonomic instability. The syndrome often develops after a sudden increase in dosage of the neuroleptic medication or in states of dehydration. Treatment is mainly supportive and includes withdrawal of the neuroleptic medication and, possibly, administration of drugs such as dantrolene and bromocriptine. Complications of NMS include acute renal failure and acute respiratory failure. Given the widespread prescription of neuroleptics by physicians in a variety of fields, all physicians need to be able to recognize and appropriately manage NMS. PMID:12952806

2016-12-01

The purpose of this narrative review was to describe the most common spinal fusion surgical procedures, address the clinical indications for lumbar fusion in degeneration cases, identify potential complications, and discuss their relevance to chiropractic management of patients after surgical fusion. The PubMed database was searched from the beginning of the record through March 31, 2015, for English language articles related to lumbar fusion or arthrodesis or both and their incidence, procedures, complications, and postoperative chiropractic cases. Articles were retrieved and evaluated for relevance. The bibliographies of selected articles were also reviewed. The most typical lumbar fusion procedures are posterior lumbar interbody fusion, anterior lumbar interbody fusion, transforaminal interbody fusion, and lateral lumbar interbody fusion. Fair level evidence supports lumbar fusion procedures for degenerative spondylolisthesis with instability and for intractable low back pain that has failed conservative care. Complications and development of chronic pain after surgery is common, and these patients frequently present to chiropractic physicians. Several reports describe the potential benefit of chiropractic management with spinal manipulation, flexion-distraction manipulation, and manipulation under anesthesia for postfusion low back pain. There are no published experimental studies related specifically to chiropractic care of postfusion low back pain. This article describes the indications for fusion, common surgical practice, potential complications, and relevant published chiropractic literature. This review includes 10 cases that showed positive benefits from chiropractic manipulation, flexion-distraction, and/or manipulation under anesthesia for postfusion lumbar pain. Chiropractic care may have a role in helping patients in pain who have undergone lumbar fusion surgery.

Long Term Sequelae of Pediatric Craniopharyngioma – Literature Review and 20 Years of Experience

2011-01-01

Craniopharyngioma are rare histologically benign brain tumors that develop in the pituitary–hypothalamic area. They may invade nearby anatomical structures causing significant rates of neurological, neurocognitive, and endocrinological complications including remarkable hypothalamic damage. Information regarding long term implications of the tumors and treatment in the pediatric population is accumulating, and treatment goals appear to be changing accordingly. In this review we aim to present data regarding long term complications of craniopharyngioma in children and adolescents and our experience from a large tertiary center. Hypothalamic dysfunction was noted to be the most significant complication, adversely affecting quality of life in survivors. Obesity, fatigue, and sleep disorders are the most notable manifestations of this dysfunction, and treatment is extremely difficult. Changes in management in recent years show a potential for improved long term outcomes; we found a trend toward less aggressive surgical management and increasing use of adjuvant treatment, accompanied by a decrease in complication rates.

Nasal vestibulitis (NV) is a common infection; however, scant data is available in the literature as it pertains to NV. We aim to describe the clinical characteristics of NV in respect to its potential complications. A retrospective chart review of 118 NV cases admitted to a tertiary medical center between 2008 and 2015. Identified risk factors for NV included nasal hair plucking (n=15, 14.41%), nose blowing (n=10, 9.32%), nose picking (n=9, 8.47%) and nose piercing (n=5, 3.39%). Twelve patients (10.17%) were diabetic, and 3 patients were immunosuppressed. Mid-facial cellulitis was observed in the majority of patients (78.81%), and abscess of the nasal vestibule was observed in almost half (48.30%). Cultures were taken from 33.33% of patients demonstrated MSSA as the most common isolate (81.25%). No complications were observed. Even in complicated cases of NV requiring admission, the risk of major complications is extremely low. Copyright © 2017 Elsevier Inc. All rights reserved.

Ocular side effects following intravitreal injection therapy for retinoblastoma: a systematic review.

Smith, Stephen J; Smith, Brian D; Mohney, Brian G

2014-03-01

To describe the ocular side effects in patients receiving intravitreal injection therapy (IViT) for retinoblastoma. PubMed (1946-present), Scopus (all years), Science Citation Index (1900-present) and Conference Proceedings Citation Index-Science (1990-present) electronic databases were searched to identify all published reports of therapeutic intravitreal injections for retinoblastoma in humans. Ten studies with original IViT ocular side effect data were included in this systematic review. In these combined reports, a total of 1287 intravitreal injections were given to 306 eyes of 295 patients, with a mean follow-up of 74.1 months. Two hundred sixty-one (88.5%) patients received comparatively standard melphalan IViT doses (8-30 mcg). Ocular side effects occurred in 38 patients (17 significant, 21 minor). The proportion of patients experiencing potentially significant ocular side effects following standard melphalan IViT regimens was 0.031 (8/261; 95% CI 0.013 to 0.06). The side effects of these eight included iris atrophy in three, two each with chorioretinal atrophy and vitreous haemorrhage and one with retinal detachment. Of the other nine patients with significant complications, five experienced sight-threatening complications following dramatic dose escalations (four with melphalan, one with thiotepa), three experienced complications that are commonly associated with concurrent therapies given to these patients and one had a retinal detachment. Of the 61 patients receiving IViT via safety-enhancing injection techniques, all six significant side effects were either attributed to the therapeutic dose or confounded by concurrent treatments. Significant ocular complications following IViT for retinoblastoma are uncommon, and this risk may be reduced further by the use of careful injection technique and standard dosing regimens. Care must be taken in the dosing of intravitreal treatments to avoid potentially irreversible vision loss.

Background & Aims The risk of serious complications after colonoscopy has important implications for the overall benefits of colorectal cancer screening programs. We evaluated the incidence of serious complications within 30 days after screening or surveillance colonoscopies in diverse clinical settings and to identify potential risk factors for complications. Methods Patients age 40 and over undergoing colonoscopy for screening, surveillance, or evaluation based an abnormal result from another screening test were enrolled through the National Endoscopic Database (CORI). Patients completed a standardized telephone interview approximately 7 and 30 days after their colonoscopy. We estimated the incidence of serious complications within 30 days of colonoscopy and identified risk factors associated with complications using logistic regression analyses. Results 21,375 patients were enrolled. Gastrointestinal bleeding requiring hospitalization occurred in 34 patients (incidence 1.59/1000 exams; 95% confidence interval [CI] 1.10–2.22). Perforations occurred in 4 patients (0.19/1000 exams; 95% CI 0.05–0.48), diverticulitis requiring hospitalization in 5 patients (0.23/1000 exams; 95% CI 0.08–0.54), and post-polypectomy syndrome in 2 patients (0.09/1000 exams; 95%CI 0.02–0.30). The overall incidence of complications directly related to colonoscopy was 2.01 per 1000 exams (95%CI 1.46–2.71). Two of the four perforations occurred without biopsy or polypectomy. The risk of complications increased with pre-procedure warfarin use and performance of polypectomy with cautery. Conclusions Complications after screening or surveillance colonoscopy are uncommon. Risk factors for complications include warfarin use and polypectomy with cautery. PMID:19850154

Guidelines of the National Comprehensive Cancer Network on the use of myeloid growth factors with cancer chemotherapy: a review of the evidence.

PubMed

Lyman, Gary H

2005-07-01

The prophylactic use of myeloid growth factors reduces the risk of chemotherapy-induced neutropenia and its complications, including febrile neutropenia and infection-related mortality. Perhaps most importantly, the prophylactic use of colony-stimulating factors (CSFs) has been shown to reduce the need for chemotherapy dose reductions and delays that may limit chemotherapy dose intensity, thereby increasing the potential for prolonged disease-free and overall survival in the curative setting. National surveys have shown that the majority of patients with potentially curable breast cancer or non-Hodgkin's lymphoma (NHL) do not receive prophylactic CSF support. In this issue, the National Comprehensive Cancer Network presents guidelines for the use of myeloid growth factors in patients with cancer. These guidelines recommend a balanced clinical evaluation of the potential benefits and harms associated with chemotherapy to define the treatment intention, followed by a careful assessment of the individual patient's risk for febrile neutropenia and its complications. The decision to use prophylactic CSFs is then based on the patient's risk and potential benefit from such treatment. The routine prophylactic use of CSFs in patients receiving systemic chemotherapy is recommended in patients at high risk (>20%) of developing febrile neutropenia or related complications that may compromise treatment. Where compelling clinical indications are absent, the potential for CSF prophylaxis to reduce or offset costs by preventing hospitalization for FN should be considered. The clinical, economic, and quality of life data in support of these recommendations are reviewed, and important areas of ongoing research are highlighted.

Comparison of ICD-9-based, retrospective, and prospective assessments of perioperative complications: assessment of accuracy in reporting.

2011-01-01

large studies of ICD-9-based complication and hospital-acquired condition (HAC) chart reviews have not been validated through a comparison with prospective assessments of perioperative adverse event occurrence. Retrospective chart review, while generally assumed to underreport complication occurrence, has not been subjected to prospective study. It is unclear whether ICD-9-based population studies are more accurate than retrospective reviews or are perhaps equally susceptible to bias. To determine the validity of an ICD-9-based assessment of perioperative complications, the authors compared a prospective independent evaluation of such complications with ICD-9-based HAC data in a cohort of patients who underwent spine surgery. For further comparison, a separate retrospective review of the same cohort of patients was completed as well. a prospective assessment of complications in spine surgery over a 6-month period (May to December 2008) was completed using an independent auditor and a validated definition of perioperative complications. The auditor maintained a prospective database, which included complications occurring in the initial 30 days after surgery. All medical adverse events were included in the assessment. All patients undergoing spine surgery during the study period were eligible for inclusion; the only exclusionary criterion used was the availability of the auditor for patient assessment. From the overall patient database, 100 patients were randomly extracted for further review; in these patients ICD-9-based HAC data were obtained from coder data. Separately, a retrospective assessment of complication incidence was completed using chart and electronic medical record review. The same definition of perioperative adverse events and the inclusion of medical adverse events were applied in the prospective, ICD-9-based, and retrospective assessments. ninety-two patients had adequate records for the ICD-9 assessment, whereas 98 patients had adequate chart information for retrospective review. The overall complication incidence among the groups was similar (major complications: ICD-9 17.4%, retrospective 19.4%, and prospective 22.4%; minor complications: ICD-9 43.8%, retrospective 31.6%, and prospective 42.9%). However, the ICD-9-based assessment included many minor medical events not deemed complications by the auditor. Rates of specific complications were consistently underreported in both the ICD-9 and the retrospective assessments. The ICD-9 assessment underreported infection, the need for reoperation, deep wound infection, deep venous thrombosis, and new neurological deficits (p = 0.003, p < 0.0001, p < 0.0001, p = 0.0025, and p = 0.04, respectively). The retrospective review underestimated incidences of infection, the need for revision, and deep wound infection (p < 0.0001 for each). Only in the capture of new cardiac events was ICD-9-based reporting more accurate than prospective data accrual (p = 0.04). The most sensitive measure for the appreciation of complication occurrence was the prospective review, followed by the ICD-9-based assessment (p = 0.05). an ICD-9-based coding of perioperative adverse events and major complications in a cohort of spine surgery patients revealed an overall complication incidence similar to that in a prospectively executed measure. In contrast, a retrospective review underestimated complication incidence. The ICD-9-based review captured many medical events of limited clinical import, inflating the overall incidence of adverse events demonstrated by this approach. In multiple categories of major, clinically significant perioperative complications, ICD-9-based and retrospective assessments significantly underestimated complication incidence. These findings illustrate a significant potential weakness and source of inaccuracy in the use of population-based ICD-9 and retrospective complication recording.

Liquid injectable silicone: a review of its history, immunology, technical considerations, complications, and potential.

For over five decades, liquid injectable silicone has been used for soft-tissue augmentation. Its use has engendered polarized reactions from the public and from physicians. Adherents of this product tout its inert chemical structure, ease of use, and low cost. Opponents of silicone cite the many reports of complications, including granulomas, pneumonitis, and disfiguring nodules that are usually the result of large-volume injection and/or industrial grade or adulterated material. Unfortunately, as recently as 2006, reports in The New England Journal of Medicine and The New York Times failed to distinguish between the use of medical grade silicone injected by physicians trained in the microdroplet technique and the use of large volumes of industrial grade products injected by unlicensed or unskilled practitioners. This review separates these two markedly different procedures. In addition, it provides an overview of the chemical structure of liquid injectable silicone, the immunology of silicone reactions within the body, treatment for cosmetic improvement including human immunodeficiency virus lipoatrophy, technical considerations for its injection, complications seen following injections, and some considerations of the future for silicone soft-tissue augmentation.

Umbilical hernia--a potential donor-site complication of fat injection laryngoplasty.

2012-11-01

Injection laryngoplasty with autologous fat appears to be an effective and simple technique for the treatment of patients with glottic insufficiency in comparison with other surgical techniques. Despite of its advantages, associated complications have also been reported, including immediate donor-site morbidity (eg, hematoma and abscess), fat extrusion of the injection site, and delayed manifestation of vocal granuloma or overinjected vocal folds. In this article, a patient suffering from accidental injury to the deep abdominal fascia without peritoneal penetration in the fat harvest procedure is presented. Three months after the fat injection laryngoplasty, an umbilical hernia was proved to occur via the clinical imaging. Several etiologies are supposed to induce the herniation of intraabdominal structures, including surgeon's incaution, abdominal obesity, intense wound inflammation and fibrosis, and the native weak point of the abdominal wall around the umbilicus. This case provides information that overdepth and negligence in fat harvest may injure the deep abdominal fascia, then possibly causing the umbilical hernia as a delayed donor-site complication.

When Should We Give Up Filtration Surgery: Indications, Techniques and Results of Cyclodestruction.

PubMed

Masis Solano, Marisse; Huang, Guofu; Lin, Shan C

2017-01-01

Cyclodestructive procedures are traditionally used in cases of glaucoma that are refractory to medical and surgical therapy. The goal of this chapter is to describe the indications, contraindications, techniques, and pitfalls of cyclodestructive procedures, including transscleral cyclophotocoagulation (TCP), micropulse TCP (MP-TCP), endoscopic cyclophotocoagulation (ECP), and ultrasound cilioplasty. A literature search for cyclodestructive techniques was performed, and relevant studies were included for evaluation and review. It is encouraging that TCP seems relatively efficacious even for patients who have been refractory to other treatments, depending on the energy setting, follow-up period, and definition of success. Repeated TCP is often required. TCP was more often used in eyes with limited visual potential caused by severe forms of glaucoma than in eyes with good visual potential. Serious complications were significant vision loss, inflammation, hypotony, and phthisis. ECP came later into clinical use for the treatment of refractory glaucoma. ECP is able to specifically target the ciliary epithelium under direct viewing as compared to TCP, which is an indirect cyclodestructive procedure. In the literature, it has been demonstrated that ECP has overall good success with relatively low complication rates when used for adult forms of glaucoma. A new technology using MP-TCP is a promising alternative to conventional cyclophotocoagulation. Early evidence shows that MP-TCP has clinical utility and a good safety profile. Ultrasound cilioplasty is a possible alternative to laser cyclodestruction that is already being commercialized and is currently under investigation. Both TCP and ECP are effective cyclodestructive procedures and alternatives for the treatment of glaucoma refractory to medical and surgical therapy, though potential for serious complications exists. TCP, ECP, and ultrasound cilioplasty are being used increasingly as the primary surgery for various kinds and stages of glaucoma. © 2017 S. Karger AG, Basel.

Squamous cell carcinoma of oral cavity is of malignant tumors, which causes cancerous complications. DNA damage, mainly because of products of oxidative stress like reactive oxygen species, is a frequent mutagenic that triggers carcinoma. Smoking increases the probability of cancer incidence. Saliva is the first biological medium to interact with external compounds, especially smoking substances. The present study overviews the salivary level of some remarkable compounds in relation with smoking and squamous cell carcinoma. To collect data, English literature was searched in databases including PubMed, ScienceDirect and Google Scholar. The keywords used for search were as follows: ‘Carcinoma, Squamous Cell’, ‘Smoking’, ‘Saliva’, and ‘Biomarkers‘. The inclusion criteria were the presence of salivary chemical factors in relation with oral cancer and influence by smoking. Out of 239 found articles, only 56 were selected. Our results demonstrated the potential role of salivary biochemistry to predict and/or treat complications with cancer in both smoker and non-smoker individuals. Changes in concentrations of salivary chemicals including antioxidants, total antioxidant, glutathione and uric acid, epithelial growth factor, cytokine biomarkers, superoxide dismutase activity, and transcriptome were related to squamous cell carcinoma and could be used as potential biomarkers for cancer prognosis; moreover, enhancement of antioxidant level might be a potential treatment.

hospital malnutrition is a frequent worldwide problem and its potential issues related include increased complications, length of stay, mortality, and healthcare costs. the aim of this study was to establish the cost-effectiveness of early nutritional therapy for malnourished patients in a high complexity hospital. this analytical study with economic assessment included 227 adult hospitalised and malnourished according to the Subjective Global Assessment. The cohort prospective received Early Nutrition Therapy (ENT), whereas the cohort retrospective received Delayed Nutrition Therapy (DNT). The measures of cost-effectiveness included costs by: length of stay, complications and discharge condition. the cohorts were similar in demographic and clinical characteristics, except that the median age, for the ENT was 61 years (interquartile range [IQR]: 48-71) and for the DNT was 55 years (IQR: 44-67) (p = 0.024). The median length of stay was lower in the ENT (11 days, IQR: 7-17) than in the DNT (18 days, IQR: 10-28) (p < 0.001). The cost per patient discharged alive was US $ 10,261.55 in the ENT and US $ 15,553.11 in the DNT (p=0.043); the cost per patient with complications was US $ 13,663.90 in the ENT and US $ 17,860.32 in the DNT (p= 0.058). ENT increased the likelihood of being discharged alive, RR adjusted=0.31; 95% confidence interval (CI): 0.1; 0.6; (p<0.001) and decreased the likelihood of complications RR crude=0.8; 95% CI: 0.6; 0.9; (p=0.006). early nutritional therapy for malnourished adult patients appears to be cost-effective because it can reduce the length of stay, complications, mortality and associated costs.

Delayed onset of non-ischemic cerebral enhancing (NICE) lesions is a rare complication of intracranial aneurysms' endovascular therapy (EVT). The purpose of this study is to report this rare complication and its potential pathophysiology in a single-center case series and review the relevant literature. After retrospective review of all patients managed by EVT at our institution from January 1, 2012 to December 31, 2014, 2 out of 374 patients (0.5 %) with such a complication were identified. Skin patch testing was performed with all endovascular devices used in the two patients and with the European baseline series, including nickel. All previously published cases in the English literature were reviewed based on exhaustive PubMed and Embase research. Patient no. 1 developed NICE lesions 1 month after balloon-assisted coiling of a ruptured anterior communicating artery aneurysm. Patient no. 2 developed NICE lesions 12 months (the longest delay reported to date for such a complication) after the treatment of a right carotid-ophthalmic aneurysm by loose coiling and flow diversion. Patient no. 2 demonstrated nickel skin reactivity, but none of the two patients presented allergic reaction to the devices used during interventions. Based on our observations and review of the literature, we hypothesize that delayed non-ischemic cerebral enhancing lesions after EVT are more likely related to foreign body emboli rather than nickel allergy. The two presented cases demonstrate the potential for recurrence and prolonged fluctuation of NICE lesions, warranting long-term follow-up for all patients presenting this complication.

Obesity is increasingly prevalent among patients undergoing surgery. Conflicting evidence exists regarding the impact of obesity on postoperative complications. This multicentre study aims to determine whether obesity is associated with increased postoperative complications following general surgery. This prospective, multicentre cohort study will be performed utilising a collaborative methodology. Consecutive adults undergoing open or laparoscopic, elective or emergency, gastrointestinal, bariatric or hepatobiliary surgery will be included. Day case patients will be excluded. The primary end point will be the overall 30-day major complication rate (Clavien-Dindo grade III-V complications). Data will be collected to risk-adjust outcomes for potential confounding factors, such as preoperative cardiac risk. This study will be disseminated through structured medical student networks using established collaborative methodology. The study will be powered to detect a two-percentage point increase in the major postoperative complication rate in obese versus non-obese patients. Following appropriate assessment, an exemption from full ethics committee review has been received, and the study will be registered as a clinical audit or service evaluation at each participating hospital. Dissemination will take place through national and local research collaborative networks. Published by the BMJ Publishing Group Limited.

1992-05-01

While endoscopically placed gastrostomy tubes are routinely simple, they are not always feasible. Endoscopic technique also does not uniformly secure the tube to the abdominal wall, which presents possible complications, including leakage, accidental early tube removal, intraperitoneal catheter migration and necrosis of the stomach or abdominal wall because of excessive traction. Presented herein is a technique that is rapid, simple and eliminates some of these potential complications. The technique is easily combined with other operative procedures, such as tracheostomy, is done under direct vision, can be performed quickly with intravenous sedation and local anesthetic and is a safe method of tube placement for enteral feeding or gastric decompression.

The incidence of diabetes mellitus has increased drastically over the past few decades. This oxidant-antioxidant imbalance resulting in complication of diabetes mellitus includes macro- and microvascular complications. Resistance to conventional treatment and patient compliance has paved the way to the usage of effective natural products and supplements. Momordica charantia (bitter gourd) is widely consumed in many parts of Malaysia as a vegetable. Momordica charantia (MC) is mainly used in the management of diabetes mellitus. The present review discusses the literature concerning the antidiabetic and antioxidant properties of MC focusing on the complication of diabetes mellitus along with its mode of delivery. We found that among the whole part of MC, its fruit extract has been widely studied, therapeutically. The evidence based analysis of the beneficiary effects of MC on the different organs involved in diabetes complication is also highlighted. This review elucidated an essential understanding of MC based drug delivery system in both clinical and experimental studies and appraised the great potential of the protein based MC extract against diabetes mellitus. The review paper is believed to assist the researchers and medical personnel in treating diabetic associated complications.

The immunological study of children with infectious parotitis (IP) without complications and with such complications as pancreatitis, meningitis or orchitis in the glandular form was carried out. In accordance with the previously proposed principle, 4 types of immune response (IR) were established on the basis of differences in initial resistance and the IR profile: cell-mediated immunity (types I and III) and humoral immunity (types II and IV). The patients included nonvaccinated children, as well as children vaccinated on epidemic indications, 3-6, 7-9, 10 and more years before infection. The comparative analysis of the number of IP cases with and without complications in the groups of children, divided according to their immunization history and the type of IR, revealed that postvaccinal immunity in children vaccinated on epidemic indications (less than a month ago) or 3-6 years before infection had protective potential, sufficient for the prevention of complicated forms of IP. Immunity obtained 7-9 years ago was effective for the protection from IP complications only in cell-mediated, but not humoral IR. Postvaccinal immunity obtained more than 10 years ago did not ensure the decrease in the occurrence of complicated forms of IP (in comparison with that in nonvaccinated patients) in children with any type of IR.

It was aimed to concern about the satisfaction and procedural complications of patients during the thoracoscopy exist of hands-on training in this present study. The patients with non-small-cell carcinoma underwent video-assisted thoracoscopic surgery (VATS) lobectomy during hands-on training courses at thoracoscopic center in our hospital and collected from January 2009 and December 2014. The rates of satisfaction and complications of patients were compared from hands-on training group and control group. Potential risk factors associated with post-VATS complications of patients and thoracoscopist-related variables were analyzed. There were 54 patients join in six meetings with hands-on thoracoscopy training in our center. There was no significant difference between patients for hands-on training group (n = 54) and control group (n = 54), including sex, age, BMI, smoking, PpoFEV1 and comorbidities. The satisfaction rate and the incidence of complication were similar between the two groups. Univariate analyses showed that elder age, heart disease, chronic obstructive pulmonary disease, long operative time, and first-time mentorship were significantly associated with post-VATS complications of patients in hands-on training group. We should pay more attention to the characteristics of patent and the experience of mentor before VATS hands-on training courses.

Intestinal perforation and necrotizing enterocolitis (NEC) are neonatal intestinal emergencies that are especially common in premature infants. While prompt surgical intervention, including stoma creation, is often required, the optimal surgical treatment has been controversial because of the substantial risks related to the stoma creation and management. The use of a tissue adhesive may have some advantages over the use of sutures when creating an intestinal stoma in extremely low birth weight (ELBW) infants. The purpose of this report was to present a novel approach for creating a stoma using a tissue adhesive in ELBW infants. A total of eight ELBW infants that underwent laparotomy with the creation of intestinal stomas using cyanoacrylate adhesive at our institution between 2009 and 2014 were enrolled. The clinical parameters, including the length of the operation, intra- and postoperative complications and the outcomes were evaluated. The median body weight and gestational age at birth were 630 g and 24.3 weeks, respectively. The median age at referral was 11.5 days. The median length of the procedure was 58.5 min, including the inspection and resection of the intestine. All procedures were completed without any intraoperative complications. There were no postoperative complications associated with the stoma. Two patients died of the associated septic status. Sutureless enterostomy using cyanoacrylate adhesive is a simple technique which has the potential to reduce the incidence of complications related to the intestinal stoma in ELBW infants.

Does Glucagon-like Peptide-1 Ameliorate Oxidative Stress in Diabetes? Evidence Based on Experimental and Clinical Studies

2016-01-01

Glucagon-like peptide-1 (GLP-1) has shown to influence the oxidative stress status in a number of in vitro, in vivo and clinical studies. Well-known effects of GLP-1 including better glycemic control, decreased food intake, increased insulin release and increased insulin sensitivity may indirectly contribute to this phenomenon, but glucose-independent effects on ROS level, production and antioxidant capacity have been suggested to also play a role. The potential ‘antioxidant’ activity of GLP-1 along with other proposed glucose-independent modes of action related to ameliorating redox imbalance remains a controversial topic but could hold a therapeutic potential against micro- and macrovascular diabetic complications. This review discusses the presently available knowledge from experimental and clinical studies on the effects of GLP-1 on oxidative stress in diabetes and diabetes-related complications.

: Diagnostic radiographic imaging scans using intravascular iodinated contrast media can lead to various complications. The most salient of these is contrast-induced acute kidney injury (CI-AKI) or contrast-induced nephropathy, a potentially costly and serious patient safety concern. Prevention strategies are the cornerstone of evidence-based clinical management for patients receiving contrast agents. These include preprocedure screening, stratification of patients based on risk factors, and protective interventions, the most important of which is hydration both before and after the radiographic imaging scan. There is a gap, however, between best evidence and clinical practice in terms of exact hydration protocols. Nurses play an important role in nephropathy prevention and need to be familiar with CI-AKI as a potential complication of radiographic imaging scans. In order to ensure safe, high-quality care, nurses must be involved in efforts to prevent CI-AKI as well as interventions that minimize patients' risk of kidney injury.

The Frost suture is a well-known surgical technique for providing upward tension on the lower lid to prevent or correct ectropion after surgical interventions in the periorbital area. Despite its relatively common use, comprehensive information on executing this technique is not readily available. To review eyelid anatomy, indications, and proper technique for performing the Frost suture, as well as potential complications. A review of the literature on Frost sutures was performed. Cadaveric dissection was performed to demonstrate placement of the Frost suture. The Frost suture is a useful method to reduce the risk of ectropion after surgery near the lower eyelid. Downward pull on the lid can occur with normal wound contracture even if ectropion is not present with the initial repair, reinforcing the need for preventive measures. Potential complications of this technique include superficial skin erosion of the upper lid, corneal abrasion, and blockage of the field of vision while the suture is in place.

To evaluate the impact of enhanced recovery after surgery (ERAS) programs on postoperative complications of pancreatic surgery. Computer searches were performed in databases (including PubMed, Cochrane Library and Embase) for randomized controlled trials or case-control studies describing ERAS programs in patients undergoing pancreatic surgery published between January 1995 and August 2017. Two researchers independently evaluated the quality of the studies' extracted data that met the inclusion criteria and performed a meta-analysis using RevMan5.3.5 software. Forest plots, demonstrating the outcomes of the ERAS group vs the control group after pancreatic surgery, and funnel plots were used to evaluate potential publication bias. Twenty case-control studies including 3694 patients, published between January 1995 and August 2017, were selected for the meta-analysis. This study included the ERAS group ( n = 1886) and the control group ( n = 1808), which adopted the traditional perioperative management. Compared to the control group, the ERAS group had lower delayed gastric emptying rates [odds ratio (OR) = 0.58, 95% confidence interval (CI): 0.48-0.72, P < 0.00001], lower postoperative complication rates (OR = 0.57, 95%CI: 0.45-0.72, P < 0.00001), particularly for the mild postoperative complications (Clavien-Dindo I-II) (OR = 0.71, 95%CI: 0.58-0.88, P = 0.002), lower abdominal infection rates (OR = 0.70, 95%CI: 0.54-0.90, P = 0.006), and shorter postoperative length of hospital stay (PLOS) (WMD = -4.45, 95%CI: -5.99 to -2.91, P < 0.00001). However, there were no significant differences in complications, such as, postoperative pancreatic fistulas, moderate to severe complications (Clavien-Dindo III- V), mortality, readmission and unintended reoperation, in both groups. The perioperative implementation of ERAS programs in pancreatic surgery is safe and effective, can decrease postoperative complication rates, and can promote recovery for patients.

Superficial liposuction has found its application in maximizing and creating a lifting effect to achieve a better aesthetic result. Due to initial high complication rates, these procedures were generally accepted as risky. In a response to the increasing concerns over the safety and efficacy of superficial liposuction, the authors describe their 14-year experience of performing superficial liposuction and analysis of postoperative complications associated with these procedures. From March of 1995 to December of 2008, the authors performed superficial liposuction on 2398 patients. Three subgroups were incorporated according to liposuction methods as follows: power-assisted liposuction alone (subgroup 1), power-assisted liposuction combined with ultrasound energy (subgroup 2), and power-assisted liposuction combined with external ultrasound and postoperative Endermologie (subgroup 3). Statistical analyses for complications were performed among subgroups. The mean age was 42.8 years, mean body mass index was 27.9 kg/m2, and mean volume of total aspiration was 5045 cc. Overall complication rate was 8.6 percent (206 patients). Four cases of skin necroses and two cases of infections were included. The most common complication was postoperative contour irregularity. Power-assisted liposuction combined with external ultrasound with or without postoperative Endermologie was seen to decrease the overall complication rate, contour irregularity, and skin necrosis. There were no statistical differences regarding other complications. Superficial liposuction has potential risks for higher complications compared with conventional suction techniques, especially postoperative contour irregularity, which can be minimized with proper selection of candidates for the procedure, avoiding overzealous suctioning of superficial layer, and using a combination of ultrasound energy techniques.

Targeting orphan G protein-coupled receptors for the treatment of diabetes and its complications: C-peptide and GPR146.

PubMed

Kolar, G R; Grote, S M; Yosten, G L C

2017-01-01

G protein-coupled receptors (GPCRs) are the most abundant receptor family encoded by the human genome and are the targets of a high percentage of drugs currently in use or in clinical trials for the treatment of diseases such as diabetes and its associated complications. Thus, orphan GPCRs, for which the ligand is unknown, represent an important untapped source of therapeutic potential for the treatment of many diseases. We have identified the previously orphan GPCR, GPR146, as the putative receptor of proinsulin C-peptide, which may prove to be an effective treatment for diabetes-associated complications. For example, we have found a potential role of C-peptide and GPR146 in regulating the function of the retinal pigment epithelium, a monolayer of cells in the retina that serves as part of the blood-retinal barrier and is disrupted in diabetic macular oedema. However, C-peptide signalling in this cell type appears to depend at least in part on extracellular glucose concentration and its interaction with insulin. In this review, we discuss the therapeutic potential of orphan GPCRs with a special focus on C-peptide and GPR146, including past and current strategies used to 'deorphanize' this diverse family of receptors, past successes and the inherent difficulties of this process. © 2016 The Association for the Publication of the Journal of Internal Medicine.

Endoscopic percutaneous gastrostomy is a safe technique although with potential complications before which the clinician has to be on alert in order to early detect them even after a long period of normal functioning. Most of them represent minor problems. Gastrocolocutaneous fistula is a rare but severe complication favored by some risk factors such as previous post-surgical adherences, deformities of the spine, or excessive gastric inflation at the time of performing the technique. We present the case of a patient with PEG with this complication that occurred after the first tube replacement. Our goal was in two senses: on the one hand, to analyze the preventive aspects and basic guidelines for a safe PEG placement to minimize the risks; on the other hand, to alert on the possible presence of this entity to prevent a progressive nutritional impairment.

The diagnostic techniques of choice are radiologic tests such as CT scan and contrast media administration through the tube.

Hypoglycemia is an important complication of glucose-lowering therapy in patients with diabetes mellitus. Attempts made at intensive glycemic control invariably increases the risk of hypoglycemia. A six-fold increase in deaths due to diabetes has been attributed to patients experiencing severe hypoglycemia in comparison to those not experiencing severe hypoglycemia Repeated episodes of hypoglycemia can lead to impairment of the counter-regulatory system with the potential for development of hypoglycemia unawareness. The short- and long-term complications of diabetes related hypoglycemia include precipitation of acute cerebrovascular disease, myocardial infarction, neurocognitive dysfunction, retinal cell death and loss of vision in addition to health-related quality of life issues pertaining to sleep, driving, employment, recreational activities involving exercise and travel. There is an urgent need to examine the clinical spectrum and burden of hypoglycemia so that adequate control measures can be implemented against this neglected life-threatening complication. Early recognition of hypoglycemia risk factors, self-monitoring of blood glucose, selection of appropriate treatment regimens with minimal or no risk of hypoglycemia and appropriate educational programs for healthcare professionals and patients with diabetes are the major ways forward to maintain good glycemic control, minimize the risk of hypoglycemia and thereby prevent long-term complications.

Taylor, Jacob; Anderson, William S; Brandt, Jason; Mari, Zoltan; Pontone, Gregory M

2016-12-01

Although Parkinson disease (PD) is defined clinically by its motor symptoms, it is increasingly recognized that much of the disability and worsened quality of life experienced by patients with PD is attributable to psychiatric symptoms. The authors describe a model of multidisciplinary care that enables these symptoms to be effectively managed. They describe neuropsychiatric complications of PD itself and pharmacologic and neurostimulation treatments for parkinsonian motor symptoms and discuss the management of these complications. Specifically, they describe the clinical associations between motor fluctuations and anxiety and depressive symptoms, the compulsive overuse of dopaminergic medications prescribed for motor symptoms (the dopamine dysregulation syndrome), and neuropsychiatric complications of these medications, including impulse control disorders, psychosis, and manic syndromes. Optimal management of these problems requires close collaboration across disciplines because of the potential for interactions among the pathophysiologic process of PD, motor symptoms, dopaminergic drugs, and psychiatric symptoms. The authors emphasize how their model of multidisciplinary care facilitates close collaboration among psychiatrists, other mental health professionals, neurologists, and functional neurosurgeons and how this facilitates effective care for patients who develop the specific neuropsychiatric complications discussed.

Infective Endocarditis Presenting as Bilateral Orbital Cellulitis: An Unusual Case

PubMed Central

Hasan, Badar; Ukani, Rehman; Pauly, Rebecca R

2017-01-01

Orbital cellulitis is a severe and sight-threatening infection of orbital tissues posterior to the orbital septum. The most common causes of orbital cellulitis are rhinosinusitis, orbital trauma, and surgery. Infective endocarditis (IE) is a systemic infection that begins on cardiac valves and spreads by means of the bloodstream to peripheral organs. Septic emboli can spread to any organ including the eyes and can cause focal or diffuse ophthalmic infection. Ocular complications of IE classically include Roth’s spots, subconjunctival hemorrhages, chorioretinitis, and endophthalmitis. IE as a cause of orbital cellulitis has been described by only one author in the literature. Here, we present a very rare case of bilateral orbital cellulitis caused by IE. Through this case, we aim to create awareness of the potential for serious ocular complications in IE and provide an overview of the management. PMID:28721318

Toxic epidermal necrolysis (TEN) is a rare, life-threatening autoimmune disease predominantly manifested in the skin and mucous membranes. Today, infectious complications have the dominant share in mortality of TEN patients. Due to the nature of the therapy and administration of immunosuppressive medications, a wide range of potentially pathogenic microorganisms, which cause infectious complications in different compartments in these patients, is not surprising. This is a multicentric study, which included all patients with TEN hospitalized between 2000-2015 in specialized centres in the Czech Republic and Slovakia. The total catchment area was over 12.5 million inhabitants. The actual implementation of the project was carried out using data obtained from the registry CELESTE (Central European LyEll Syndrome: Therapeutic Evaluation), when specific parameters relating to epidemiological indicators and infectious complications in patients with TEN were evaluated in the form of a retrospective analysis. In total, 39 patients with TEN were included in the study (12 patients died, mortality was 31%), who were hospitalized in the monitored period. The median age of patients in the group was 63 years (the range was 4-83 years, the mean was 51 years), the median of the exfoliated area was 70% TBSA (total body surface area) (range 30-100%, mean 67%). SCORTEN was calculated for 38 patients on the day of admission. Its median in all patients was 3 (range 1-6; mean 3). Any kind of infectious complication in the study group was recorded in 33 patients in total (85%). In total, 30 patients (77%) were infected with gram-positive cocci, 27 patients (69%) with gram-negative rods, and yeast cells or fibrous sponge were cultivated in 12 patients (31%). A total of 32 patients (82%) were found to have infectious complications in the exfoliated area, 15 patients (39%) had lower respiratory tract infections, 18 patients (46%) urinary tract infections and 15 patients (39%) an infection in the bloodstream. The most common potentially pathogenic microorganism isolated in our study group was coagulase neg. Staphylococcus, which caused infectious complications in 24 patients. Enterococcus faecalis/faecium (19 patients), Pseudomonas aeruginosa (17 patients), Staphylococcus aureus (11 patients) and Escherichia coli (11 patients) were other most frequently isolated micro-organisms. The published data were obtained from the unique registry of TEN patients in Central Europe. In the first part, we have succeeded in defining the basic epidemiological indicators in the group of patients anonymously included in this registry. The study clearly confirms that infectious complications currently play an essential role in TEN patients, often limiting the chances of survival. The study also shows a high prevalence of these complications in the period after 15days from the start of hospitalization, when most patients already have completely regenerated skin cover.

In this review, we describe current and future potential wound healing treatments for acute and chronic wounds. The current wound healing approaches are based on autografts, allografts, and cultured epithelial autografts, and wound dressings based on biocompatible and biodegradable polymers. The Food and Drug Administration approved wound healing dressings based on several polymers including collagen, silicon, chitosan, and hyaluronic acid. The new potential therapeutic intervention for wound healing includes sustained delivery of growth factors, and siRNA delivery, targeting microRNA, and stem cell therapy. In addition, environment sensors can also potentially utilize to monitor and manage microenvironment at wound site. Sensors use optical, odor, pH, and hydration sensors to detect such characteristics as uric acid level, pH, protease level, and infection - all in the hopes of early detection of complications.

Surgical monitoring with auditory evoked potentials.

PubMed

Lüders, H

1988-07-01

This comprehensive review of surgical monitoring with auditory evoked potentials (AEPs) includes a detailed discussion of techniques used for recording brainstem auditory evoked potentials, direct eight-nerve potentials, and electrocochleograms. The normal waveform of these different potentials is discussed, and the typical patterns of abnormalities seen with different insults to the peripheral or central auditory pathways are presented. The mechanisms most probably responsible for changes in AEPs during surgical procedures are analyzed. A critical analysis is made of what represents a significant change in AEPs. Also considered is the predictive value of intrasurgical changes of AEPs. Finally, attempts are made to determine whether AEPs monitoring can assist the surgeon in the prevention of postsurgical complications.

Risk of Endophthalmitis and Other Long-Term Complications of Trabeculectomy in the Collaborative Initial Glaucoma Treatment Study (CIGTS)

Purpose To report the risk of endophthalmitis and other long-term complications in patients randomized to trabeculectomy in the Collaborative Initial Glaucoma Treatment Study (CIGTS). Design A longitudinal cohort study using data collected from a multicenter, randomized clinical trial. Methods Long-term post-operative complications in the 300 patients randomized to trabeculectomy in CIGTS were tabulated. Kaplan-Meier analyses were used to estimate the time-related probability of blebitis, hypotony, and endophthalmitis. Results 285 patients were included in the final trabeculectomy cohort after accounting for assignment refusal and other early events. Patients were followed for an average of 7.2 years. 163 patients (57%) received 5-fluorouracil (5-FU) intraoperatively. Of the 247 patients with at least 5 years of follow-up, 50 required further treatment for glaucoma. Cataract extraction was performed in 57 patients (20%). Forty patients (14%) required bleb revision at least once. Bleb-related complications included bleb leak (N = 15), blebitis (N = 8), and hypotony (N = 4). Three patients were noted to have endophthalmitis, although the diagnosis in two patients was presumptive. The occurrences of blebitis, hypotony, or endophthalmitis were not significantly associated with 5-FU use. The Kaplan-Meier calculated risks of blebitis and hypotony at 5 years were both 1.5%, while the risk of endophthalmitis was 1.1%. Conclusions The potential efficacy of trabeculectomy must be weighed against the long-term risk of complications, especially endophthalmitis, when selecting treatments for patients with open-angle glaucoma. We report a low 5-year risk of endophthalmitis (1.1%) and other bleb-related complications in the trabeculectomy cohort of the CIGTS. PMID:23246272

On categorizing gestational, birth, and neonatal complications following late pregnancy exposure to antidepressants: the prenatal antidepressant exposure syndrome.

PubMed

Gentile, Salvatore

2010-03-01

Late in utero exposure to antidepressants has been suspected of adversely impacting pregnancy outcome and compromising neonatal adaptation. Hence, the necessity exists to analyze published information on antidepressant use during late pregnancy to individuate potential recurrent patterns of iatrogenic complications. Computerized searches on MEDLINE, PsycINFO, ENBASE, and Cochrane Library through February 10, 2010 were performed for selecting literature information and investigating the safety of antidepressants when used during late pregnancy. Antidepressant treatment during late pregnancy may increase the rates of poor pregnancy outcome and neonatal withdrawal/toxic reactions. Because both gestational complications and neonatal adverse events acknowledge the same etiology, the author suggests including such iatrogenic events under the definition of prenatal antidepressant exposure syndrome, in order to increase clinicians' awareness about the spectrum of risks which may concern the mother-infant pair when antidepressant treatment is deemed indispensable during late pregnancy.

Intrahospital transportation of critically ill patients is associated with significant complications. In order to reduce overall risk to the patient, such transports should well organized, efficient, and accompanied by the proper monitoring, equipment, and personnel. Protocols and guidelines for patient transfers should be utilized universally across all healthcare facilities. Care delivered during transport and at the site of diagnostic testing or procedure should be equivalent to the level of care provided in the originating environment. Here we review the most common problems encountered during transport in the hospital setting, including various associated adverse outcomes. Our objective is to make medical practitioners, nurses, and ancillary health care personnel more aware of the potential for various complications that may occur during patient movement from the intensive care unit to other locations within a healthcare facility, focusing on risk reduction and preventive strategies.

2017-11-01

Flexor tenolysis surgery for flexor digitorum profundus and superficialis adhesions is a common procedure performed by hand surgeons. Releasing these adhered tendons can greatly improve hand function and improve quality of life. Recent evidence, however, has shown that the outcomes of tenolysis surgeries are often suboptimal and can result in relapsing adhesions or even tendon ruptures. This article describes a new technique with potential for reduced complication rates: The Fine Wire Technique for Flexor Tenolysis (FWT). Following FWT, the patient detailed in this article had an excellent recovery of function and no complications: including tendon rupture, infection, hematomas, or any other complications. She reported a major improvement from her preoperative functionality and continues to have this level of success. The wire's thinness allows for a swift tenolysis. The FWT is a new option available to the hand surgeon associated with good functional results. The wire is readily available to the clinician and is also inexpensive.

EX-PRESS Glaucoma Filtration Device: efficacy, safety, and predictability

PubMed Central

Chan, Jessica E; Netland, Peter A

2015-01-01

Trabeculectomy has been the traditional primary surgical therapy for open-angle glaucoma. While trabeculectomy is effective in lowering intraocular pressure, complications associated with the procedure have motivated the development of alternative techniques and devices, including the EX-PRESS Glaucoma Filtration Device. This review describes the efficacy, safety, complication rates, and potential advantages and disadvantages of the EX-PRESS Glaucoma Filtration Device. EX-PRESS implantation is technically simpler compared with that of trabeculectomy, with fewer surgical steps. Vision recovery has been more rapid after EX-PRESS implantation compared with trabeculectomy. Intraocular pressure variation is lower during the early postoperative period, indicating a more predictable procedure. While efficacy of the EX-PRESS implant has been comparable to trabeculectomy, postoperative complications appear less common after EX-PRESS implantation compared with trabeculectomy. The EX-PRESS Glaucoma Filtration Device appears to be safe and effective in the surgical management of open-angle glaucoma. PMID:26366105

To assess the surgical efficacy and potential advantages of laparoendoscopic single-site adrenalectomy (LESS-AD) compared with conventional laparoscopic adrenalectomy (CL-AD) based on published literature. An online systematic search in electronic databasesM including Pubmed, Embase, and the Cochrane Library, as well as manual bibliography searches were performed. All studies that compared LESS-AD with CL-AD were included. The outcome measures were the patient demographics, tumor size, blood loss, operative time, time to resumption of oral intake, hospital stay, postoperative pain, cosmesis satisfaction score, rates of complication, conversion, and transfusion. A meta-analysis of the results was conducted. A total of 443 patients were included: 171 patients in the LESS-AD group and 272 patients in the CL-AD group (nine studies). There was no significant difference between the two groups in any of the demographic parameters expect for lesion size (age: P=0.24; sex: P=0.35; body mass index: P=0.79; laterality: P=0.76; size: P=0.002). There was no significant difference in estimated blood loss, time to oral intake resumption, and length of stay between the two groups. The LESS-AD patients had a significantly lower postoperative visual analog pain score compared with the CL-AD group, but a longer operative time was noted. Both groups had a comparable cosmetic satisfaction score. The two groups had a comparable rate of complication, conversion, and transfusion. In early experience, LESS-AD appears to be a safe and feasible alternative to its conventional laparoscopic counterpart with decreased postoperative pain noted, albeit with a longer operative time. As a promising and emerging minimally invasive technique, however, the current evidence has not verified other potential advantages (ie, cosmesis, recovery time, convalescence, port-related complications, etc.) of LESS-AD.

Spinal Cord Injury After Extremity Surgery in Children With Thoracic Kyphosis.

2015-10-01

Spinal cord injury is a rare complication after lower extremity surgery in children with skeletal dysplasia and thoracic kyphosis. We encountered two patients who had this complication, from among 51 (39 from Nemours/Alfred I. duPont Hospital for Children and 12 from Seattle Children's Hospital) who underwent lower extremity surgery during an 8.5-year period (June 2004 to December 2012). Because spinal cord injury is a devastating complication likely not known to most physicians treating patients with skeletal dysplasias, we sought to examine factors that may contribute to this rare complication. We performed a retrospective review of two patients with skeletal dysplasia who had paraplegia develop after extremity surgery. Outcome measures included operative time, vital signs, and postsurgery recovery of neurologic deficit. MR images were reviewed. Two patients were found-an 8.5-year-old boy with spondyloepiphyseal dysplasia congenita with a 76°-thoracic kyphosis apex at T4 and a 6.5-year-old boy with mucopolysaccharidosis type 1-H with an 80°-thoracic kyphosis apex at T2. Bilateral proximal femoral osteotomies or bilateral innominate and proximal femoral osteotomies had been performed. The spinal cord injuries occurred at the apex of the kyphosis as determined by clinical examination and MRI assessment. In both patients, the mean arterial blood pressure decreased below 50 mm Hg and might be a factor in the etiology of the paralysis. The first patient recovered motor function in 5 months; the second had no recovery. Paraplegia is extremely rare after nonspine operations. Many factors contribute to the risk for a spinal cord event: low mean arterial pressure, duration of the surgery, position on the operating table, the kyphotic spine deformity, or unappreciated vascular disease. Motor-evoked potentials and somatosensory-evoked potentials together potentially provide high sensitivity and specificity for predicting a postoperative neurologic deficit. Based on our two patients with skeletal dysplasia and a literature review of patients with hyperkyphosis undergoing extremity surgery, the surgeon must be aware of the risk of spinal cord injury. Careful preoperative assessment possibly including MRI of the spine is recommended. Mean arterial pressure should be maintained at a safe level; neuromonitoring should be considered.

Background Neck of femur fractures and their subsequent operative fixation are associated with high rates of perioperative morbidity and mortality. Consenting in this setting is suboptimal with the Montgomery court ruling changing the perspective of consent. This quality improvement project assessed the adequacy of consenting against British Orthopaedic Association-endorsed guidance and implemented a series of changes to improve the documentation of risks associated with surgery for fractured neck of femur. Methods Seventy consecutive patients who underwent any operative fixation of a neck of femur fracture were included over a 6-month period at a single centre. Patients unable to consent or without electronic notes were excluded. Consent forms were analysed and the documented potential risks or complications associated with surgery were compared to British Orthopaedic Association-endorsed guidance. A series of changes (using the plan, do study, act (PDSA) approach) was implemented to improve the adequacy of consent. Results Documentation of four out of 12 potential risks or complications was recorded in <50% of cases for patients with intracapsular fractures (n=35), and documentation of seven out of 12 potential risks or complications was recorded in <50% of cases for patients with extracapsular fractures (n=35). Re-audit following raising awareness and attaching consent guidance showed 100% documentation of potential risks or complications in patients with intracapsular and extracapsular fractures (n=70). A neck of femur fracture-specific consent form has been implemented which will hopefully lead to sustained improvement. Conclusions Consenting patients with fractured neck of femur for surgery in the authors' unit was suboptimal when compared to British Orthopaedic Association-endorsed consent guidance. This project has shown that ensuring such guidance is readily available has improved the adequacy of consent. The authors hope that introduction of a neck of femur fracture-specific consent form within their unit will lead to sustained adequate documentation of risks associated with surgery.

2018-06-01

Laser skin resurfacing (LSR) has been used for facial rejuvenation for the last 20 years. Posttreatment care after LSR is essential to decrease the risk of complications. Currently, no unified standards or criteria exist for invasive LSR posttreatment care. We aimed to identify the optimal wound care timing and choice of specific local, systemic, and general medical measures required to decrease complications. We performed a systematic search of the PubMed/MEDLINE electronic databases and included only articles written and published in the English language, with no restrictions on the publication time (year). The search yielded 316 potentially relevant articles, 133 of which met our review criteria. Most of the studies on this topic have focused on wound care during the early stage, typically the first 2 weeks. Closed dressings may offer a more ideal, moist wound environment. The use of medications must be judicious. The ongoing emergence of new methods and products warrants evaluation in future large clinical trials. Familiarity with the complications following invasive LSR and the provision of optimal, effective, and timely posttreatment care may substantially decrease the risks associated with the treatment modality.

Lakoski, Susan; Mackey, John R.; Douglas, Pamela S.; Haykowsky, Mark J.; Jones, Lee W.

2013-01-01

Molecularly targeted therapeutics (MTT) are the future of cancer systemic therapy. They have already moved from palliative therapy for advanced solid malignancies into the setting of curative-intent treatment for early-stage disease. Cardiotoxicity is a frequent and potentially serious adverse complication of some targeted therapies, leading to a broad range of potentially life-threatening complications, therapy discontinuation, and poor quality of life. Low-cost pleiotropic interventions are therefore urgently required to effectively prevent and/or treat MTT-induced cardiotoxicity. Aerobic exercise therapy has the unique capacity to modulate, without toxicity, multiple gene expression pathways in several organ systems, including a plethora of cardiac-specific molecular and cell-signaling pathways implicated in MTT-induced cardiac toxicity. In this review, we examine the molecular signaling of antiangiogenic and HER2-directed therapies that may underpin cardiac toxicity and the hypothesized molecular mechanisms underlying the cardioprotective properties of aerobic exercise. It is hoped that this knowledge can be used to maximize the benefits of small molecule inhibitors, while minimizing cardiac damage in patients with solid malignancies. PMID:23335619

Predicting excess cost for older inpatients with clinical complexity: A retrospective cohort study examining cognition, comorbidities and complications

Draper, Brian; Berry, Helen; Karmel, Rosemary; Goss, John

2018-01-01

Background Hospital-acquired complications increase length of stay and contribute to poorer patient outcomes. Older adults are known to be at risk for four key hospital-acquired complications (pressure injuries, pneumonia, urinary tract infections and delirium). These complications have been identified as sensitive to nursing characteristics such as staffing levels and level of education. The cost of these complications compared to the cost of admission severity, dementia, other comorbidities or age has not been established. Method To investigate costs associated with nurse-sensitive hospital-acquired complications in an older patient population 157,178 overnight public hospital episodes for all patients over age 50 from one Australian state, 2006/07 were examined. A retrospective cohort study design with linear regression analysis provided modelling of length-of-stay costs. Explanatory variables included patient age, sex, comorbidities, admission severity, dementia status, surgical status and four complications. Extra costs were based on above-average length-of-stay for each patient’s Diagnosis Related Group from hospital discharge data. Results For adults over 50 who have length of stay longer than average for their diagnostic condition, comorbid dementia predicts an extra cost of A$874, (US$1,247); any one of four key complications predicts A$812 (US$1,159); each increase in admission severity score predicts A$295 ($US421); each additional comorbidity predicts A$259 (US$370), and for each year of age above 50 predicts A$20 (US$29) (all estimates significant at p<0.0001). Discussion Hospital-acquired complications and dementia cost more than other kinds of inpatient complexity, but admission severity is a better predictor of excess cost. Because complications are potentially preventable and dementia care in hospitals can be improved, risk-reduction strategies for common complications, particularly for patients with dementia could be cost effective. Conclusions Complications and dementia were found to cost more than other kinds of inpatient complexity. PMID:29474407

Methods We conducted a hospital-based cross-sectional study in the Maternity Teaching Hospital in Erbil city from 1 June to 31 December 2013. All MDs and NMs that occurred in the hospital during the study period were included in the study. Systematic identification of all eligible women was done. This identification included a baseline assessment of the severe pregnancy-related complications using the World Health Organization NM criteria. Results Severe preeclampsia and postpartum hemorrhage (PPH) constituted the highest proportions of complications in women with potentially life-threatening conditions (PLTCs) (30.5% and 30.0%, respectively). The highest mortality indexes were those for ruptured uterus (16.7) and severe complications of placenta previa (14.2). Factors that were significantly associated with MD (compared to NM) were hepatic dysfunction (p = 0.046), multiple/unspecified disorders (p = 0.003), arrival as an emergency condition by ambulance (p = 0.015), and history of previous cesarean section (p = 0.013). Conclusions Severe preeclampsia and PPH are the main complications that lead to PLTCs. Factors found to be associated with MDs are hepatic dysfunction, multiple/unspecified disorders, arrival as an emergency condition by ambulance, and history of a previous cesarean section.

Angiotensin-converting enzyme inhibitor-related angioedema (ACEI-RA) is a well-described condition, yet isolated genital ACEI-RA is a little-known entity. A case of isolated genital angioedema is presented with photographic documentation. Possible complications and therapeutic options are discussed. A 71-year-old man presented with painless, nonpruritic genital swelling of 4 h duration. Medical history included peptic ulcer disease, hypertension, and benign prostatic hypertrophy. His medications included pantoprazole, hydrochlorothiazide, and lisinopril, which he had been taking for 3 years without any recent change in dosing. He was otherwise asymptomatic and previously had been in good health generally. The physical examination was positive only for diffuse, soft, nonpitting edema isolated to the scrotum and uncircumcised penis. The foreskin was only partially retractable. Urinalysis was normal. All symptoms resolved without complications within 48 h of discontinuing lisinopril and had not recurred at follow-up 4 months later. All cases of ACEI-RA isolated to the genitals that have been reported in the literature resolved without complications. ACEI-RA can present as isolated swelling of the genitals and is a potential cause of genital swelling. Patients who have no evidence of airway compromise, paraphimosis, or urinary retention from complications such as phimosis can be safely discharged with instructions to discontinue the offending agent and to return in case of development of the aforementioned conditions.

Buckberry, Sam; Bianco-Miotto, Tina; Roberts, Claire T

2014-01-01

Pregnancy outcome is inextricably linked to placental development, which is strictly controlled temporally and spatially through mechanisms that are only partially understood. However, increasing evidence suggests non-coding RNAs (ncRNAs) direct and regulate a considerable number of biological processes and therefore may constitute a previously hidden layer of regulatory information in the placenta. Many ncRNAs, including both microRNAs and long non-coding transcripts, show almost exclusive or predominant expression in the placenta compared with other somatic tissues and display altered expression patterns in placentas from complicated pregnancies. In this review, we explore the results of recent genome-scale and single gene expression studies using human placental tissue, but include studies in the mouse where human data are lacking. Our review focuses on the ncRNAs epigenetically regulated through genomic imprinting or X-chromosome inactivation and includes recent evidence surrounding the H19 lincRNA, the imprinted C19MC cluster microRNAs, and X-linked miRNAs associated with pregnancy complications.

Ornithine transcarbamylase (OTC) deficiency is the most common inborn error in the metabolism of the urea cycle with an incidence of 1 in 14 000 live births. Pregnancy can trigger potentially fatal hyperammonemic crises. We report a successful pregnancy in a 29-year-old primiparous patient with a known diagnosis of OTC deficiency since infancy. Hyperammonemic complications were avoided due to careful multidisciplinary management which included a detailed antenatal, intrapartum and postnatal plan. Management principles include avoidance of triggers, a low-protein diet and medications which promote the removal of nitrogen by alternative pathways. Triggers include metabolic stress such as febrile illness, particularly gastroenteritis, fasting and any protein loading. In our case the patient, in addition to a restricted protein intake, was prescribed sodium benzoate 4 g four times a day, sodium phenylbutyrate 2 g four times a day and arginine 500 mg four times a day to aid excretion of ammonia and reduce flux through the urea cycle.

Hospital readmissions can be detrimental to patients and may interfere with the potential benefits of the therapeutic procedure. Government agencies have begun to focus on reducing readmissions; however, the etiology of readmissions is lacking. To report the national rates, risk factors, and outcomes associated with 30- and 90-d readmissions following surgery for intractable epilepsy. We queried the Nationwide Readmissions Database from January to September 2013 using International Classification of Diseases, Ninth Edition, Clinical Modification codes to identify all patients with intractable epilepsy, who underwent hemispherectomy (01.52), brain lobectomy (01.53), amydalohippocampectomy, or partial lobectomy (01.59). Predictor variables included epilepsy type, presurgical diagnostic testing, surgery type, medical complications, surgical complications, and discharge disposition. In 1587 patients, the 30- and 90-d readmission rates were 11.5% and 16.8%, respectively. The most common reasons for readmission were persistent epilepsy, video electroencephalography monitoring, postoperative infection, and postoperative central nervous system complication. In multivariable analysis, risk factors associated with both 30- and 90-d readmission were Medicare payer status, lowest quartile of median income, depression, hemispherectomy, and postoperative complications (P < .05). The only unique predictor of 30-d readmission was small bedsize hospital (P = .001). Readmissions within 30 d were associated with longer length of stay (6.8 vs 5.8 d), greater costs ($18 660 vs $15 515), and increased adverse discharges (26.4% vs 21.8%). Following epilepsy surgery, most readmissions that occurred within 30 d can be attributed to management of persistent epilepsy and predicted by Medicare payer status, depression, and complications. These data can assist the clinician in preventing readmissions and assist policy makers determine which admissions are potentially avoidable.

The periprocedural protocol for atrial fibrillation (AF) ablation commonly includes anticoagulation therapy. Apixaban, a direct oral anticoagulant, is currently approved for clinical use; however, little is known about the effects of residual apixaban concentration on bleeding complications during/after AF ablation. Therefore, we measured residual apixaban concentration by using mass spectrometry and examined the anticoagulant's residual effects on bleeding complications. Fifty-eight patients (Mean age of 64.7±12.5 years; 31 males, 27 females) were enrolled and administered apixaban twice daily. We analyzed trough apixaban concentration, activated clotting time (ACT), heparin dose, and bleeding complications during/after AF ablation. Apixaban concentrations were directly measured using mass spectrometry. Bleeding complications were observed in 19 patients (delayed hemostasis at the puncture site, 16; hematuria, 3; hemosputum, 1). No patient required blood transfusion. The mean trough apixaban concentration was significantly lower in patients with bleeding complications than without (152.4±73.1 vs. 206.8±98.8 ng/mL respectively, P =0.037), while the heparin dose to achieve ACT>300 s was significantly higher in patients with bleeding complications (9368.4±2929.0 vs. 7987.2±2135.2 U/body respectively, P =0.046). Interestingly, a negative correlation was found between the trough apixaban concentration and the heparin dose to achieve ACT>300 s ( P =0.033, R=-0.281). Low residual plasma apixaban is associated with a higher incidence of bleeding complications during/after AF ablation, potentially because of a greater heparin requirement during AF ablation.

Anterior lumbar surgery is associated with certain perioperative visceral and vascular complications. The aim of this study was to document all general surgery-related adverse events and complications following minilaparotomic retroperitoneal lumbar procedures and to discuss strategies for their management or prevention. The authors analyzed data obtained in 412 patients who underwent anterior lumbosacral surgery between 2003 and 2005. The series comprised 114 men and 298 women whose mean age was 56 years (range 34-79 years). Preoperative diagnoses were as follows: isthmic spondylolisthesis (32%), degenerative spondylolisthesis (24%), instability/stenosis (15%), degenerative disc disease (15%), failed-back surgery syndrome (7%), and lumbar degenerative kyphosis or scoliosis (7%). A single level was exposed in 264 patients (64%), 2 in 118 (29%), and 3 or 4 in 30 (7%). The average follow-up period was 16 months. Overall, 52 instances of complications and adverse events occurred in 50 patients (12.1%), including sympathetic dysfunction in 25 (6.06%), vascular injury repaired with/without direct suture in 12 (2.9%), ileus lasting > 3 days in 5 (1.2%), pleural effusion in 4 (0.97%), wound dehiscence in 2 (0.49%), symptomatic retroperitoneal hematoma in 2 (0.49%), angina in 1 (0.24%), and bowel laceration in 1 patient (0.24%). There was no instance of retrograde ejaculation in male patients, and most complications had no long-term sequelae. This report presents a detailed analysis of complications related to anterior lumbar surgery. Although the incidence of complications appears low considering the magnitude of the procedure, surgeons should be aware of these potential complications and their management.

Plasmodium ovale is one of the causative agents of human malaria. Plasmodium ovale infection has long been thought to be non-fatal. Due to its lower morbidity, P. ovale receives little attention in malaria research. Two Malaysians went to Nigeria for two weeks. After returning to Malaysia, they fell sick and were admitted to different hospitals. Plasmodium ovale parasites were identified from blood smears of these patients. The species identification was further confirmed with nested PCR. One of them was successfully treated with no incident of relapse within 12-month medical follow-up. The other patient came down with malaria-induced respiratory complication during the course of treatment. Although parasites were cleared off the circulation, the patient's condition worsened. He succumbed to multiple complications including acute respiratory distress syndrome and acute renal failure. Sequencing of the malaria parasite DNA from both cases, followed by multiple sequence alignment and phylogenetic tree construction suggested that the causative agent for both malaria cases was P. ovale curtisi. In this report, the differences between both cases were discussed, and the potential capability of P. ovale in causing severe complications and death as seen in this case report was highlighted. Plasmodium ovale is potentially capable of causing severe complications, if not death. Complete travel and clinical history of malaria patient are vital for successful diagnoses and treatment. Monitoring of respiratory and renal function of malaria patients, regardless of the species of malaria parasites involved is crucial during the course of hospital admission.

Pathological retinal neovascularization (RNV) is a common micro-vascular complication in several retinal diseases including retinopathy of prematurity, diabetic retinopathy, age-related macular degeneration and central vein occlusion. The current therapeutic modalities of RNV are invasive and although they may slow or halt the progression of the disease they are unlikely to restore normal acuity. Therefore, there is an urgent need to develop treatment modalities, which are less invasive and therefore associated with fewer procedural complications and systemic side effects. This review article summarizes our understanding of the pathophysiology and current treatment of RNV in ischemic retinopathies; lists potential therapeutic targets; and provides a framework for the development of future treatment modalities.

We present an unusual ocular complication during the perioperative period, bilateral orbital edema in an otherwise healthy child after an outpatient surgical procedure. Ocular complications under general anesthesia remain a rare event. When periorbital edema is present, the appropriate work-up includes ruling out the potential for an allergic event by reviewing the medications administered and serum tryptase testing. Ophthalmology consultation should be considered to exclude pathology native to the eye itself. An allergist may assist in confirming a diagnosis and for allergic testing, if indicated. In our patient, the eventual diagnosis of exclusion was that of a localized reaction to the cellophane-based eye tape. PMID:21655032

Sickle cell-induced ischemic colitis is a rare yet potentially fatal complication of sickle cell anemia. Frequent pain crises with heavy analgesia may obscure and prolong this important diagnosis. Our patient was a 29-year-old female with sickle cell disease who was admitted with left lower quadrant abdominal pain. A diagnostic workup, including chemistries, complete blood count, blood cultures, chest x-ray, computerized tomography scanning, and colonoscopy, was performed to identify the etiology of her symptoms. This case highlights the importance of differentiating simple pain crisis from more serious and life-threatening ischemic bowel. A review of the literature compares this case to others reported and gives a method for diagnosing and treating this complication of sickle cell disease.

Cystic echinococcosis (CE) can affect the heart and the vena cava but few cases are reported. A retrospective case series of 11 patients with cardiac and/or endovascular CE, followed-up over a period of 15 years (1995-2009) is reported. Main clinical manifestations included thoracic pain or dyspnea, although 2 patients were asymptomatic. Cysts were located mostly in the right atrium and inferior vena cava. Nine patients were previously diagnosed with disseminated CE. Echocardiography was the diagnostic method of choice, although serology, electrocardiogram, chest X-ray, computed tomography/magnetic resonance imaging and histology aided with diagnosis and follow-up. Nine patients underwent cardiac surgery and nine received long-term antiparasitic treatment for a median duration of 25 months (range 4-93 months). One patient died intra-operatively due to cyst rupture and endovascular dissemination. Two patients died 10 and 14 years after diagnosis, due to pulmonary embolism (PE) and cardiac failure, respectively. One patient was lost to follow-up. Patients who had cardiac involvement exclusively did not have complications after surgery and were considered cured. There was only one recurrence requiring a second operation. Patients with vena cava involvement developed PEs and presented multiple complications. Cardiovascular CE is associated with a high risk of potentially lethal complications. Clinical manifestations and complications vary according to cyst location. Isolated cardiac CE may be cured after surgery, while endovascular extracardiac involvement is associated with severe chronic complications. CE should be included in the differential diagnosis of cardiovascular disease in patients from endemic areas. © 2012 Díaz-Menéndez et al.

To report the outcomes and complications of reverse shoulder arthroplasty (RSA) in massive irreparable rotator cuff tears (MIRCT) and cuff tear arthropathy (CTA). A systematic review of the literature contained in Medline, Cochrane, EMBASE, Google Scholar and Ovid databases was conducted on May 1, 2016, according to PRISMA guidelines. The key words "reverse total shoulder arthroplasty" or "reverse total shoulder prostheses" with "rotator cuff tears"; "failed rotator cuff surgery"; "massive rotator cuff tears"; "irreparable rotator cuff tears"; "cuff tear arthropathy"; "outcomes"; "complications" were matched. All articles reporting outcomes and complications of RSA for the management of MIRCT or CTA were included. The comparison between preoperative and postoperative clinical scores, as well as range of motion (ROM), was performed using the Wilcoxon-Mann-Whitney test. P values lower than 0.05 were considered statistically significant. Seven articles were included in our qualitative synthesis. A statistically significant improvement in all clinical scores and ROM was found comparing the preoperative value with the postoperative value. The degrees of retroversion of the humeral stem of the RSA do not influence the functional outcomes in a statistically significant fashion. There were 17.4% of complications. The most frequent was heterotopic ossification, occurring in 6.6% of patients. Revision surgery was necessary in 7.3% of patients. RSA restores pain-free ROM and improves function of the shoulder in patients with MIRCT or CTA. However, complications occur in a high percentage of patients. The lack of level I studies limits the real understanding of the potentials and limitations of RSA for the management of MIRCT and CTA.

To assess the impact of postoperative complications on full in-hospital costs per case. Rising expenses for complex medical procedures combined with constrained resources represent a major challenge. The severity of postoperative complications reflects surgical outcomes. The magnitude of the cost created by negative outcomes is unclear. Morbidity of 1200 consecutive patients undergoing major surgery from 2005 to 2008 in a tertiary, high-volume center was assessed by a validated, complication score system. Full in-hospital costs were collected for each patient. Statistical analysis was performed using a multivariate linear regression model adjusted for potential confounders. This study population included 393 complex liver/bile duct surgeries, 110 major pancreas operations, 389 colon resections, and 308 Roux-en-Y gastric bypasses. The overall 30-day mortality rate was 1.8%, whereas morbidity was 53.8%. Patients with an uneventful course had mean costs per case of US$ 27,946 (SD US$ 15,106). Costs increased dramatically with the severity of postoperative complications and reached the mean costs of US$ 159,345 (SD US$ 151,191) for grade IV complications. This increase in costs, up to 5 times the cost of a similar operation without complications, was observed for all types of investigated procedures, although the magnitude of the increase varied, with the highest costs in patients undergoing pancreas surgery. This study demonstrates the dramatic impact of postoperative complications on full in-hospital costs per case and that complications are the strongest indicator of costs. Furthermore, the study highlights a relevant savings capacity for major surgical procedures, and supports all efforts to lower negative events in the postoperative course.

2017-03-01

We analysed the association between economic incentives and diagnostic coding practice in the Norwegian public health care system. Data included 3,180,578 hospital discharges in Norway covering the period 1999-2008. For reimbursement purposes, all discharges are grouped in diagnosis-related groups (DRGs). We examined pairs of DRGs where the addition of one or more specific diagnoses places the patient in a complicated rather than an uncomplicated group, yielding higher reimbursement. The economic incentive was measured as the potential gain in income by coding a patient as complicated, and we analysed the association between this gain and the share of complicated discharges within the DRG pairs. Using multilevel linear regression modelling, we estimated both differences between hospitals for each DRG pair and changes within hospitals for each DRG pair over time. Over the whole period, a one-DRG-point difference in price was associated with an increased share of complicated discharges of 14.2 (95 % confidence interval [CI] 11.2-17.2) percentage points. However, a one-DRG-point change in prices between years was only associated with a 0.4 (95 % CI [Formula: see text] to 1.8) percentage point change of discharges into the most complicated diagnostic category. Although there was a strong increase in complicated discharges over time, this was not as closely related to price changes as expected.

Homocysteine in renovascular complications: hydrogen sulfide is a modulator and plausible anaerobic ATP generator.

Homocysteine (Hcy) is a non-protein amino acid derived from dietary methionine. High levels of Hcy, known as hyperhomocysteinemia (HHcy) is known to cause vascular complications. In the mammalian tissue, Hcy is metabolized by transsulfuration enzymes to produce hydrogen sulfide (H2S). H2S, a pungent smelling gas was previously known for its toxic effects in the central nervous system, recent studies however has revealed protective effects in a variety of diseases including hypertension, diabetes, inflammation, atherosclerosis, and renal disease progression and failure. Interestingly, under stress conditions including hypoxia, H2S can reduce metabolic demand and also act as a substrate for ATP production. This review highlights some of the recent advances in H2S research as a potential therapeutic agent targeting renovascular diseases associated with HHcy. Copyright © 2014 Elsevier Inc.

Controversial therapeutics: the β-adrenergic antagonist and cocaine-associated cardiovascular complications dilemma.

PubMed

Schurr, James W; Gitman, Brenda; Belchikov, Yuly

2014-12-01

Cocaine abuse is associated with cardiovascular complications that include chest pain and myocardial infarction. Traditional therapy for these conditions includes a β-adrenergic antagonist. However, guidelines released in 2008 recommended against this treatment option because of the prevailing theory that cocaine will potentiate vasospasm secondary to unopposed α-adrenergic effects. Subsequently, further evidence and updated guidelines have become available, debunking this claim. Current literature is limited but suggests that β-adrenergic antagonists are harmful. Although case reports support a detrimental effect of β-adrenergic antagonists, the anecdotal data are inconsistent, and the conclusions from case studies are overruled by larger studies. The pharmacology, pathophysiology, and literature on the use of β-adrenergic antagonists in association with cocaine are reviewed. Future studies that focus on outcomes and different pharmacologic profiles of β-adrenergic antagonists are needed. © 2014 Pharmacotherapy Publications, Inc.

Venous thromboembolism (VTE), a disease that includes deep venous thrombosis (DVT) and pulmonary embolism (PE), is associated with high mortality, morbidity, and costs. It can result in long-term complications that include postthrombotic syndrome (PTS) adding to its morbidity. VTE affects 1/1000 patients, costs $13.5 billion annually to treat, and claims 100,000 lives annually in the US. The current standard of care for VTE is anticoagulation, though thrombolysis may be performed in patients with PE and threatened limb. This review discusses pathogenesis and medical treatment of VTE and then focuses on endovascular treatment modalities. Mechanical- and catheter-directed thrombolysis (CDT) is discussed, as well as patient selection criteria, and complications. The first prospective study (CaVenT) comparing CDT with anticoagulation alone in acute DVT, despite study shortcomings, corroborates the existing literature indicating improved outcomes with CDT. The potential of the ongoing prospective, multicenter, randomized ATTRACT trial is also highlighted. PMID:28154761

Tracheobronchial stents are most commonly used to restore patency to airways stenosed by tumour growth. Currently all tracheobronchial stents are associated with complications such as stent migration, granulation tissue formation, mucous plugging and stent strut fracture. The present work develops a computational framework to evaluate tracheobronchial stent designs in vivo. Pressurised computed tomography is used to create a biomechanical lung model which takes into account the in vivo stress state, global lung deformation and local loading from pressure variation. Stent interaction with the airway is then evaluated for a number of loading conditions including normal breathing, coughing and ventilation. Results of the analysis indicate that three of the major complications associated with tracheobronchial stents can potentially be analysed with this framework, which can be readily applied to the human case. Airway deformation caused by lung motion is shown to have a significant effect on stent mechanical performance, including implications for stent migration, granulation formation and stent fracture.

End stage liver disease (ESLD) is associated with significant thrombotic complications. In this study, we attempted to determine if patients with ESLD, due to oncologic or autoimmune diseases, are susceptible to thrombosis to a greater extent than patients with ESLD due to other causes. In this retrospective study, we analyzed the UNOS database to determine the incidence of thrombotic complications in orthotopic liver transplant (OLT) recipients with autoimmune and oncologic conditions. Between 2000 and 2012, 65,646 OLTs were performed. We found 4,247 cases of preoperative portal vein thrombosis (PVT) and 1,233 cases of postoperative vascular thrombosis (VT) leading to graft failure. Statistical evaluation demonstrated that patients with either hepatocellular carcinoma (HCC) or autoimmune hepatitis (AIC) had a higher incidence of PVT (p = 0.05 and 0.03 respectively). Patients with primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and AIC had a higher incidence of postoperative VT associated with graft failure (p < 0.0001, p < 0.0001, p = 0.05 respectively). Patients with preoperative PVT had a higher incidence of postoperative VT (p < 0.0001). Multivariable logistic regression demonstrated that patients with AIC, and BMI ≥40, having had a transjugular intrahepatic portosystemic shunt, and those with diabetes mellitus were more likely to have preoperative PVT: odds ratio (OR)(1.36, 1.19, 1.78, 1.22 respectively). Patients with PSC, PBC, AIC, BMI ≤18, or with a preoperative PVT were more likely to have a postoperative VT: OR (1.93, 2.09, 1.64, 1.60, and 2.01, respectively). Despite the limited number of variables available in the UNOS database potentially related to thrombotic complications, this analysis demonstrates a clear association between autoimmune causes of ESLD and perioperative thrombotic complications. Perioperative management of patients at risk should include strategies to reduce the potential for these complications.

This paper concerns the potential use of compounds, including lipid A, chitosan, and carrageenan, from marine sources as agents for treating endotoxemic complications from Gram-negative infections, such as sepsis and endotoxic shock. Lipid A, which can be isolated from various species of marine bacteria, is a potential antagonist of bacterial endotoxins (lipopolysaccharide (LPSs)). Chitosan is a widespread marine polysaccharide that is derived from chitin, the major component of crustacean shells. The potential of chitosan as an LPS-binding and endotoxin-neutralizing agent is also examined in this paper, including a discussion on the generation of hydrophobic chitosan derivatives to increase the binding affinity of chitosan to LPS. In addition, the ability of carrageenan, which is the polysaccharide of red alga, to decrease the toxicity of LPS is discussed. We also review data obtained using animal models that demonstrate the potency of carrageenan and chitosan as antiendotoxin agents.

Infectious mononucleosis may lead to numerous complications. Tonsillar hyperplasia with risk of airway obstruction is well known. Dacryocystitis is a rare but potentially severe complication. A 6-year-old child with primary mononucleosis infectious diagnosed 8 days before, developed acute dacryocystitis, with rapid evolution to orbital cellulitis, despite adequate antibiotherapy. Emergency surgical drainage was required. Dacryocystitis is a rare and little documented complication of EBV infection. Its acute evolution to orbital cellulitis is possible and potentially severe. Its physiopathology is specific. Patients are initially free of chronic stenosis and epiphora, which express acute obstruction of the lachrymal sac due to general lymphoid hyperplasia.

2015-08-01

Diabetes and its cardiovascular complications have been a major public health issue. These complications are mainly attributable to a severe imbalance between free radical and reactive oxygen species production and the antioxidant defense systems. Nuclear factor E2-related factor 2 (Nrf2) is a transcription factor that controls the basal and inducible expression of a battery of antioxidant enzyme genes and other cyto-protective phase II detoxifying enzymes. As a result, Nrf2 has gained great attention as a promising drug target for preventing diabetic cardiovascular complications. And while animal studies have shown that several Nrf2 activators manifest a potential to efficiently prevent the diabetic complications, their use in humans has not been approved due to the lack of substantial evidence regarding safety and efficacy of the Nrf2 activation. We provide here a brief review of a few clinically-used drugs that can up-regulate Nrf2 with the potential of extending their usage to diabetic patients for the prevention of cardiovascular complications and conclude with a closer inspection of dimethyl fumarate and its mimic members.

Auricular or high helical ear piercing is an increasingly widespread fashion trend that is associated with an increased risk of potentially serious post-piercing complications such as auricular perichondritis. An 11-year-old girl developed severe auricular perichondritis following piercing of the upper helical cartilage of her ear at a hairdressing salon. Four days post piercing, she returned to the same salon for a haircut during which the pierced site was manipulated. She presented to her family physician and was treated unsuccessfully with oral cephalexin. She was then referred to an infectious diseases consultant and received antipseudomonal intravenous antibiotics with subsequent resolution. She also required debridement and removal of necrotic cartilage. Public health investigation evaluated potential sources of infection including the piercing gun, disinfectant solutions, and hair cutting spray water bottles. Final culture results of the ear helical aspirate grew Pseudomonas aeruginosa. Pseudomonas aeruginosa was also cultured from one of the water bottles used to wet her hair during the haircut. Although the pseudomonal strains from the water bottle were different than the infecting one, this contamination presents a potential source of wound infection. Damage to the helical cartilage caused by the piercing gun may also have contributed to this infection. Initial empiric antibiotic therapy for these kinds of infection must include anti-pseudomonal coverage. Auricular or high helical ear piercing using a piercing gun is not recommended.

Degenerative disc and facet joint disease of the lumbar spine is common in the ageing population, and is one of the most frequent causes of disability. Lumbar spondylosis may result in mechanical back pain, radicular and claudicant symptoms, reduced mobility and poor quality of life. Surgical interbody fusion of degenerative levels is an effective treatment option to stabilize the painful motion segment, and may provide indirect decompression of the neural elements, restore lordosis and correct deformity. The surgical options for interbody fusion of the lumbar spine include: posterior lumbar interbody fusion (PLIF), transforaminal lumbar interbody fusion (TLIF), minimally invasive transforaminal lumbar interbody fusion (MI-TLIF), oblique lumbar interbody fusion/anterior to psoas (OLIF/ATP), lateral lumbar interbody fusion (LLIF) and anterior lumbar interbody fusion (ALIF). The indications may include: discogenic/facetogenic low back pain, neurogenic claudication, radiculopathy due to foraminal stenosis, lumbar degenerative spinal deformity including symptomatic spondylolisthesis and degenerative scoliosis. In general, traditional posterior approaches are frequently used with acceptable fusion rates and low complication rates, however they are limited by thecal sac and nerve root retraction, along with iatrogenic injury to the paraspinal musculature and disruption of the posterior tension band. Minimally invasive (MIS) posterior approaches have evolved in an attempt to reduce approach related complications. Anterior approaches avoid the spinal canal, cauda equina and nerve roots, however have issues with approach related abdominal and vascular complications. In addition, lateral and OLIF techniques have potential risks to the lumbar plexus and psoas muscle. The present study aims firstly to comprehensively review the available literature and evidence for different lumbar interbody fusion (LIF) techniques. Secondly, we propose a set of recommendations and guidelines for the indications for interbody fusion options. Thirdly, this article provides a description of each approach, and illustrates the potential benefits and disadvantages of each technique with reference to indication and spine level performed.

Early diagnosis of complications after severe trauma by specific biomarkers remains difficult. Identify potential new biomarkers for early diagnosis of post-traumatic complications. Mice underwent pressure-controlled hemorrhage or sham procedure. Four hours later, genome-wide expression of isolated Kupffer cells was compared with controls using Affymetrix-Genechip-Expression-Analysis and real-time-PCR. Expression analysis and real-time-PCR revealed a significant increase of gene expression of Cxcl10, Il4ra, Csf2rb2, Lcn2, and Gbp5. Cxcl10, Il4ra, Csf2rb2, Lcn2, and Gbp5 might represent new biomarkers for early diagnosis of post-traumatic complications, if they are linked to the development of post-traumatic complications.

The Spontaneously Diabetic Torii (SDT) rat is an inbred strain of Sprague-Dawley rat and recently is established as a nonobese model of type 2 diabetes (T2D). Male SDT rats show high plasma glucose levels (over 700 mg/dL) by 20 weeks. Male SDT rats show pancreatic islet histopathology, including hemorrhage in pancreatic islets and inflammatory cell infiltration with fibroblasts. Prior to the onset of diabetes, glucose intolerance with hypoinsulinemia is also observed. As a result of chronic severe hyperglycemia, the SDT rats develop profound complications. In eyes, retinopathy, cataract, and neovascular glaucoma are observed. Proliferative retinopathy, especially, resulting from retinal neovascular vessels is a unique characteristic of this model. In kidney, mesangial proliferation and nodular lesion are observed. Both peripheral neuropathy such as decreased nerve conduction velocity and thermal hypoalgesia and autonomic neuropathy such as diabetic diarrhea and voiding dysfunction have been reported. Osteoporosis is another complication characterized in SDT rat. Decreased bone density and low-turnover bone lesions are observed. Taking advantage of these features, SDT rat has been used for evaluating antidiabetic drugs and drugs/gene therapy for diabetic complications. In conclusion, the SDT rat is potentially a useful T2D model for studies on pathogenesis and treatment of diabetic complications in humans. PMID:23691526

To characterize a spinal cord injury (SCI) population from the 2008 Sichuan earthquake in China; to evaluate functional outcomes of physical rehabilitation interventions; to assess potential determinants of rehabilitation effectiveness; and to assess medical complications and management outcomes. A total of 51 earthquake victims with SCI were enrolled and underwent rehabilitation programming. Functional rehabilitation outcomes included ambulation ability, wheelchair mobility and activities of daily living (ADL) assessed with the Modified Barthel Index at the beginning and end of rehabilitation. Effectiveness of rehabilitation and the effect of other predictors were evaluated by mixed effects regression. Outcomes of medical complication management were determined by comparison of the incidence of respective complications at the beginning and end of rehabilitation. Ambulation, wheelchair mobility and ADL were significantly improved with rehabilitation programming. Both earlier rescue and earlier onset of rehabilitation were significant positive predictors of rehabilitation effectiveness, whereas delayed onset of rehabilitation combined with prolonged time to rescue resulted in a lesser positive effect. Medical complications were managed effectively in 63% (pressure ulcers) to 85% (deep vein thrombosis) of patients during rehabilitation. Earthquake victims with SCI may achieve significantly improved functional rehabilitation functional outcomes on a formal, institutional-based physical rehabilitation programme.

1997-06-01

To evaluate the postoperative computed tomographic (CT) appearance, complications, and potential pitfalls after a Puestow procedure (lateral side-to-side pancreaticojejunostomy). Forty CT examinations were performed after the Puestow procedure in 20 patients. Images were retrospectively reviewed by three radiologists. The pancreaticojejunal anastomosis was identified at 30 examinations and was immediately anterior to the pancreatic body or tail. The anastomosis contained fluid or gas on 11 scans and oral contrast material on four scans. On 15 scans, the anastomosis appeared as collapsed bowel without gas, fluid, or oral contrast material. The Roux-en-Y loop was identified on 28 (70%) scans and contained fluid or gas on 16 scans and oral contrast material on six scans. The Roux-en-Y loop appeared as collapsed bowel on six scans. When the anastomosis or Roux-en-Y loop contained fluid and gas, the appearance mimicked that of a pancreatic or parapancreatic abscess. Peripancreatic stranding was present on 28 scans and was due to either ongoing pancreatitis or postoperative change. Complications included 15 transient fluid collections, three abscesses, four pseudocysts, one hematoma, and one small-bowel and Roux-en-Y obstruction. Knowledge of the anatomy after a Puestow procedure is essential for accurate interpretation of CT scans.

Advanced concepts in knee arthrodesis.

The aim is to describe advanced strategies that can be used to diagnose and treat complications after knee arthrodesis and to describe temporary knee arthrodesis to treat infected knee arthroplasty. Potential difficult complications include nonunited knee arthrodesis, limb length discrepancy after knee arthrodesis, and united but infected knee arthrodesis. If a nonunited knee arthrodesis shows evidence of implant loosening or failure, then bone grafting the nonunion site as well as exchange intramedullary nailing and/or supplemental plate fixation are recommended. If symptomatic limb length discrepancy cannot be satisfactorily treated with a shoe lift, then the patient should undergo tibial lengthening over nail with a monolateral fixator or exchange nailing with a femoral internal lengthening device. If a united knee arthrodesis is infected, the nail must be removed. Then the surgeon has the option of replacing it with a long, antibiotic cement-coated nail. The authors also describe temporary knee arthrodesis for infected knee arthroplasty in patients who have the potential to undergo insertion of a new implant. The procedure has two goals: eradication of infection and stabilization of the knee. A temporary knee fusion can be accomplished by inserting both an antibiotic cement-coated knee fusion nail and a static antibiotic cement-coated spacer. These advanced techniques can be helpful when treating difficult complications after knee arthrodesis and treating cases of infected knee arthroplasty.

Ureteric substitution using the Yang-Monti principle was reported as a modification of simple ileal ureter replacement. During April 2013 to June in 2015, 2 patients underwent ileal ureteral substitution using a reconfigured ileal segment of Yang Monti principle in our clinical center. Some slight modifications were made and then follow-up were carried out up to 12 months. For these 2 cases, no significant intra/post-operative complications occurred. In 1 year follow up, serum creatinine (Scr) and blood urea nitrogen (BUN) of both patients decreased to normal.Glomerular filtration rate (GFR), renogram and pyelogram showed a stable split renal function. To better understand the Yang-Monti principle and potential risks and complications, we conduct an systemic review by searching PubMed, Google Scholar and the Cochrane Library database from January 1996 through June 2016. 10 out of 644 publications were identified, which included 269 patients from cohort studies. The most usual indications for Yang-monti therapy were iatrogenic stricture and retroperitoneal fibrosis. Infection and ileus were indicated as themain short time postoperative complications while the fistula and re- strictures happened in long-term. In general,we believe Yang-Monti Principle is a safer and efficient technique for clinical partial and complete ureteral defects if patients and potential risks could be well prepared.

Assessment of the risk of antiangiogenic agents before and after surgery.

Bailey, Christina E; Parikh, Alexander A

2018-05-08

Angiogenesis plays a critical role in the growth, progression, and metastasis of numerous solid tumor types, and thus, antiangiogenic agents have been studied for many years as potential therapeutic agents. Many different antiangiogenic agents, including monoclonal antibodies and multi-targeted tyrosine kinase inhibitors (TKIs), have been approved for various oncology indications, and promising clinical activity has been demonstrated. However, some of these agents have also been associated with serious safety concerns. Because angiogenesis is an important step in the wound healing process, agents targeting the angiogenesis pathway may interfere with wound healing, thus increasing the risk of surgical wound complications, such as dehiscence, surgical site bleeding, and wound infection. Nevertheless, antiangiogenic agents can be safely used in the perioperative setting if oncologists and surgeons are educated on the biology and pharmacokinetics of these agents. This review discusses the available published literature regarding surgical complications associated with the use of antiangiogenic agents and provides updated clinical recommendations on the optimal timing between surgery and antiangiogenic therapy. Due to the paucity of data surrounding this topic, current and future clinical trials need to evaluate prospectively the potential risks for surgical complications associated with antiangiogenic therapies to establish specific guidelines for their safe and effective use within the surgical oncology community.

Diagnosis and initial management of cerebellar infarction.

Edlow, Jonathan A; Newman-Toker, David E; Savitz, Sean I

2008-10-01

Cerebellar infarction is an important cause of stroke that often presents with common and non-specific symptoms such as dizziness, nausea and vomiting, unsteady gait, and headache. Accurate diagnosis frequently relies on careful attention to patients' coordination, gait, and eye movements--components of the neurological physical examination that are sometimes omitted or abridged if cerebellar stroke is not specifically being considered. The differential diagnosis is broad, and includes many common and benign causes. Furthermore, early-stage posterior fossa ischaemia is rarely seen with brain CT--the most commonly available initial imaging test that is used for stroke. Insufficient examination and imaging can result in misdiagnosis. However, early correct diagnosis is crucial to help prevent treatable but potentially fatal complications, such as brainstem compression and obstructive hydrocephalus. The identification and treatment of the underlying vascular lesions at an early stage can also prevent subsequent occurrences of stroke and improve patients' outcomes. Here, we review the clinical presentation of cerebellar infarction, from diagnosis and misdiagnosis to patients' monitoring, treatment, and potential complications.

The importance of a proper against-medical-advice (AMA) discharge: how signing out AMA may create significant liability protection for providers.

Every year, patients leave the Emergency Department against medical advice (AMA) and before an adequate evaluation can be performed. It is well known that many of these patients are at risk of subsequent complications. The goal of this article is to explain the potential legal protections that may be created from a proper AMA discharge. In this article, the authors review the steps that need to be taken when performing an AMA discharge, including an assessment of capacity, proper documentation, and adequate disclosure. The authors then review the potential legal protections that can result from a properly documented and performed discharge. Among these protections are: proof that the provider's duty to the patient ended with discharge and that the patient assumed the risk of a subsequent complication. The authors conclude that a properly executed discharge can provide significant legal protection from liability risks. Copyright © 2012 Elsevier Inc. All rights reserved.

Improvements in Metabolic Health with Consumption of Ellagic Acid and Subsequent Conversion into Urolithins: Evidence and Mechanisms12

Kang, Inhae; Buckner, Teresa; Gu, Liwei

2016-01-01

Ellagic acid (EA) is a naturally occurring polyphenol found in some fruits and nuts, including berries, pomegranates, grapes, and walnuts. EA has been investigated extensively because of its antiproliferative action in some cancers, along with its anti-inflammatory effects. A growing body of evidence suggests that the intake of EA is effective in attenuating obesity and ameliorating obesity-mediated metabolic complications, such as insulin resistance, type 2 diabetes, nonalcoholic fatty liver disease, and atherosclerosis. In this review, we summarize how intake of EA regulates lipid metabolism in vitro and in vivo, and delineate the potential mechanisms of action of EA on obesity-mediated metabolic complications. We also discuss EA as an epigenetic effector, as well as a modulator of the gut microbiome, suggesting that EA may exert a broader spectrum of health benefits than has been demonstrated to date. Therefore, this review aims to suggest the potential metabolic benefits of consumption of EA-containing fruits and nuts against obesity-associated health conditions. PMID:27633111

Cytopenias among ART-naive patients with advanced HIV disease on enrolment to care and treatment services at a tertiary hospital in Tanzania: A cross-sectional study.

HIV/AIDS causes high morbidity and mortality through both immunosuppression and complications not directly related to immunosuppression. Haematological abnormalities, including various cytopenias, occur commonly in HIV through immune and non-immune pathways. Though these complications could potentially cause serious clinical implications, published literature on the magnitude of this problem and its associated factors in Tanzania is scarce. This study aimed at determining the prevalence and risk factors of HIV-associated cytopenias among ART-naive patients enrolling for care and treatment services at Bugando Care and Treatment Centre (CTC) in Mwanza, Tanzania. This was a cross-sectional clinic-based study done between March 2015 and February 2016, involving all antiretroviral therapy (ART)-naive adult HIV-positive patients enrolling for care and treatment services at Bugando CTC. Patients younger than 18 years and those with missing data were excluded. Data were analysed using Stata version 11 to determine the prevalence and risk factors of cytopenias. A total of 1205 ART-naive patients were included. Median age was 41 years (interquartile range [IQR] 32 to 48). Most participants were female (n = 789; 65.6%), with a female-to-male ratio of 2:1. The median baseline CD4 count was 200 cells/µL (IQR 113 to 439). About half (49%) of the study participants had baseline CD4 counts less than 200 cells/µL. Anaemia, leucopenia, and thrombocytopenia were found in 704 (58.4%), 285 (23.6%), and 174 (14.4%) participants, respectively, and these were strongly associated with advanced HIV infection. The magnitude of cytopenias is high among ART-naive HIV-positive adults, and cytopenias are more marked with advanced HIV infection. Early diagnosis of HIV and timely initiation of ART could potentially reduce the number of people living with advanced HIV disease and its associated complications, including the cytopenias investigated in this study. Patients with cytopenias should undergo thorough screening for tuberculosis, which is an important and treatable correlate of cytopenia, in addition to close follow-up for any potential negative outcomes.

Whether adult general surgeons should handle pediatric emergencies is controversial. In many resource-limited settings, pediatric surgeons are not available. The study examined differences in surgical outcomes among children/adolescents managed by pediatric and adult general surgery teams for emergency general surgical (EGS) conditions at a university-hospital in South Asia. Pediatric patients (<18y) admitted with an EGS diagnosis (March 2009-April 2014) were included. Patients were dichotomized by adult vs. pediatric surgical management team. Outcome measures included: length of stay (LOS), mortality, and occurrence of ≥1 complication(s). Descriptive statistics and multivariable regression analyses with propensity scores to account for potential confounding were used to compare outcomes between the two groups. Quasi-experimental counterfactual models further examined hypothetical outcomes, assuming that all patients had been treated by pediatric surgeons. A total of 2323 patients were included. Average age was 7.1y (±5.5 SD); most patients were male (77.7%). 1958 (84.3%) were managed by pediatric surgery. The overall probability of developing a complication was 1.8%; 0.9% died (all adult general surgery). Patients managed by adult general surgery had higher risk-adjusted odds of developing complications (OR [95%CI]: 5.42 [2.10-14.00]) and longer average LOS (7.98 vs. 5.61 days, p < 0.01). 39.8% fewer complications and an 8.2% decrease in LOS would have been expected if all patients had been managed by pediatric surgery. Pediatric patients had better post-operative outcomes under pediatric surgical supervision, suggesting that, where possible in resource-constrained settings, resources should be allocated to promote development and staffing of pediatric surgical specialties parallel to adult general surgical teams.

To assess differences in the incidence, type, and management of complications encountered with implantation of percutaneous osseointegrated bone conduction devices when using a 9 mm abutment versus 6 mm abutment at initial implantation. Retrospective cohort study. One hundred thirty consecutive patients between January 2010 and December 2011 underwent single-stage percutaneous osseointegrated bone conduction device implantation using a 9 or 6 mm abutment. Clinical outcomes assessed for the two groups included the incidence, type, and management of postoperative complications. Abutment size, age, sex, indication for surgery, implant device type, duration of follow-up, and patient comorbidities were evaluated as potential factors affecting outcomes. Average duration of follow-up was 16 months (range 6-29 mo). Postoperative complications occurred in 38 (29.2%) patients. Twenty-four (18.4%) patients experienced minor complications requiring simple, local care; eight (6.1%) patients required in-office procedural intervention; and six (4.6%) patients required revision surgery in the operating room. Implant extrusion occurred in three (2.3%) patients. Eleven (8.5%) patients required placement of a longer abutment. Patients receiving the 6 mm abutment at initial surgery were significantly more likely to encounter a complication requiring in-office procedural intervention or revision surgery (p = 0.001). Minor complications after implantation of percutaneous osseointegrated bone conduction devices are common. The vast majority of these complications are due to localized skin reactions, most of which are readily addressed through local care. Patients receiving the 9 mm abutment during initial implantation are significantly less likely to require in-office procedural intervention or revision surgery postoperatively as compared with those receiving the shorter, 6 mm abutment.

Delayed sternal closure (DSC) is commonly used to optimize hemodynamic stability after neonatal and infant heart surgery. We hypothesized that duration of sternum left open (SLO) was associated with rate of infection complications, and that location of sternal closure may mitigate infection risk. Infants (age ≤365 days) undergoing index operations with cardiopulmonary bypass and DSC at STS Congenital Heart Surgery Database centers (from 2007 to 2013) with adequate data quality were included. Primary outcome was occurrence of infection complication, defined as one or more of the following: endocarditis, pneumonia, wound infection, wound dehiscence, sepsis, or mediastinitis. Multivariable regression models were fit to assess association of infection complication with: duration of SLO (days), location of DSC procedure (operating room versus elsewhere), and patient and procedural factors. Of 6,127 index operations with SLO at 100 centers, median age and weight were 8 days (IQR, 5-24) and 3.3 kg (IQR, 2.9-3.8); 66% of operations were STAT morbidity category 4 or 5. At least one infection complication occurred in 18.7%, compared with 6.6% among potentially eligible neonates and infants without SLO. Duration of SLO (median, 3 days; IQR, 2-5) was associated with an increased rate of infection complications (p < 0.001). Location of DSC procedure was operating room (16%), intensive care unit (67%), or other (17%). Location of DSC was not associated with rate of infection complications (p = 0.45). Rate of occurrence of infectious complications is high among infants with sternum left open following cardiac surgery. Longer duration of SLO is associated with increased infection complications.

Background There is increasing complexity in the management of patients with acute severe exacerbation of inflammatory bowel disease (IBD; Crohn’s disease (CD), ulcerative colitis (UC)) with frequent requirement for urgent surgery. Aim To determine whether a weekend effect exists for IBD care in the United States. Methods We used data from the Nationwide Inpatient Sample (NIS) 2007, the largest all-payer hospitalization database in the United States. Discharges with a diagnosis of CD or UC who underwent urgent intestinal surgery within 2 days of hospitalization were identified using the appropriate ICD-9 codes. The independent effect of admission on a weekend was examined using multivariate logistic regression adjusting for potential confounders. Results Our study included 7,112 urgent intestinal surgeries in IBD patients, 21% of which occurred following weekend admissions. There was no difference in disease severity between weekend and weekday admissions. Post-operative complications were more common following weekend than weekday hospitalizations in UC (odds ratio (OR) 1.71, 95% confidence interval (CI) 1.01–2.90). The most common post-operative complication was post-operative infections (Weekend 30% vs. weekday 20%, p=0.04). The most striking difference between weekend and weekday hospitalizations was for need for repeat laparotomy (OR 11.5), mechanical wound complications (OR 10.03) and pulmonary complications (OR 2.22). In contrast, occurrence of any post-operative complication in CD was similar between weekday and weekend admissions. Conclusion Patients with UC hospitalized on a weekend undergoing urgent surgery within 2 days have an increased risk for post-operative complications, in particular mechanical wound complications, need for repeat laparotomy, and post-operative infections.

Traumatic lesions of the olecranon bursa (OB) and prepatellar bursa (PB) are injuries commonly seen in orthopaedic trauma units. These injuries are associated with a high rate of complications. At present, only little is known about the incidence, complication rate, and treatment approaches in patients with acute open bursae. A total of 552 patients who had been treated for acute traumatic lesions of either the olecranon bursa or the prepatellar bursa, or both at our department were retrospective identified in the years between 2009 and 2014. An analysis of the medical history of these patients was carried out to investigate the incidence of bursa injuries, circumstances, concomitant injuries, complication rate, and treatment approaches. In addition, a systematic literature search on PubMed was conducted. The incidence of traumatic lesions of the OB or PB in trauma patients was 0.2% (198/100,000; 62% OB, 38% PB). Bursectomy was performed in 83.7%. Concomitant injuries were present in 41% of the cases, with no significant influence on the complication rate (P = 0.367). The overall complication rate was 19.7%. Revision surgery was necessary in 4.5% of the patients. No significant differences between OB and PB injuries were noted with regard to the complication rate (P = 0.221). There were also no significant differences in the complication rate between patients who received bursectomy and those with conservative treatment (P = 0.364). Regression analyses showed that prophylactic antibiotic administration significantly reduced the risk of infection (P = 0.04). Traumatic lesions of the OB and PB are associated with a high risk of complications. Prophylactic antibiotic therapy can potentially reduce the risk of infection and the need for revision surgery.

Over recent years, use of the LigaSure™ vessel sealing device has increased in major abdominal surgery to include pancreaticoduodenectomy (PD). LigaSure™ use during PD has expanded to include all steps of the procedure, including the division of the uncinate margin. This introduces the potential for thermal major vascular injury or margin positivity. The aim of the present study was to evaluate the safety and efficacy of LigaSure™ usage in PD in comparison to established dissection techniques. One hundred and forty-eight patients who underwent PD from 2007 to 2012 at Robert Wood Johnson University Hospital were identified from a retrospective database. Two groups were recognized: those in which the LigaSure™ device was used (N = 114), and in those it was not (N = 34). Peri-operative outcomes were compared. Vascular intra-operative complications directly caused by thermal injury from LigaSure™ use occurred in 1.8% of patients. Overall vascular intra-operative complications, uncinate margin positivity, blood loss, length of stay, and complication severity were not significantly different between groups. The mean operative time was 77 min less (P < 0.010) in the LigaSure™ group. Savings per case where the LigaSure™ was used amounted to $1776.73. LigaSure™ usage during PD is safe and effective. It is associated with decreased operative times, which may decrease operative costs in PD. © 2013 International Hepato-Pancreato-Biliary Association.

Participant attrition in longitudinal studies can introduce systematic bias, favoring participants who return for follow-up, and increase the likelihood that those with complications will be underestimated. Our aim was to examine the effectiveness of home follow-up (Home F/U) to complete the final study evaluation on potentially "lost" participants by: 1) evaluating the impact of including and excluding potentially "lost" participants (e.g., those who required Home F/U to complete the final evaluation) on the rates of study complications; 2) examining the relationship between timing and number of complications on the requirement for subsequent Home F/U; and 3) determining predictors of those who required Home F/U. We used data from a randomized controlled trial (RCT) conducted from 1991-1994 among coronary artery bypass graft surgery patients that investigated the effect of High mean arterial pressure (MAP) (intervention) vs. Low MAP (control) during cardiopulmonary bypass on 5 complications: cardiac morbidity/mortality, neurologic morbidity/mortality, all-cause mortality, neurocognitive dysfunction and functional decline. We enhanced completion of the final 6-month evaluation using Home F/U. Among 248 participants, 61 (25%) required Home F/U and the remaining 187 (75%) received Routine F/U. By employing Home F/U, we detected 11 additional complications at 6 months: 1 major neurologic complication, 6 cases of neurocognitive dysfunction and 4 cases of functional decline. Follow-up of 61 additional Home F/U participants enabled us to reach statistical significance on our main trial outcome. Specifically, the High MAP group had a significantly lower rate of the Combined Trial Outcome compared to the Low MAP group, 16.1% vs. 27.4% (p=0.032). In multivariate analysis, participants who were ≥ 75 years (OR=3.23, 95% CI 1.52-6.88, p=0.002) or on baseline diuretic therapy (OR=2.44, 95% CI 1.14-5.21, p=0.02) were more likely to require Home F/U. In addition, those in the Home F/U group were more likely to have sustained 2 or more complications (p=0.05). Home visits are an effective approach to reduce attrition and improve accuracy of study outcome reporting. Trial results may be influenced by this method of reducing attrition. Older participants, those with greater medical burden and those who sustain multiple complications are at higher risk for attrition.

Using a large, current, regional registry of percutaneous coronary interventions (PCI), we identified risk factors for postprocedure vascular complications and developed a scoring system to estimate individual patient risk. A vascular complication (access-site injury requiring treatment or bleeding requiring transfusion) is a potentially avoidable outcome of PCI. Data were collected on 18,137 consecutive patients undergoing PCI in northern New England from January 1997 to December 1999. Multivariate regression was used to identify characteristics associated with vascular complications and to develop a scoring system to predict risk. The rate of vascular complication was 2.98% (541 cases). Variables associated with increased risk in the multivariate analysis included age >or=70, odds ratio (OR) 2.7, female sex (OR 2.4), body surface area <1.6 m(2) (OR 1.9), history of congestive heart failure (OR 1.4), chronic obstructive pulmonary disease (OR 1.5), renal failure (OR 1.9), lower extremity vascular disease (OR 1.4), bleeding disorder (OR 1.68), emergent priority (OR 2.3), myocardial infarction (OR 1.7), shock (1.86), >or=1 type B2 (OR 1.32) or type C (OR 1.7) lesions, 3-vessel PCI (OR 1.5), use of thienopyridines (OR 1.4) or use of glycoprotein IIb/IIIa receptor inhibitors (OR 1.9). The model performed well in tests for significance, discrimination, and calibration. The scoring system captured 75% of actual vascular complications in its highest quintiles of predicted risk. Predicting the risk of post-PCI vascular complications is feasible. This information may be useful for clinical decision-making and institutional efforts at quality improvement.

Percutaneous nephrolithotomy (PNL) is a minimally invasive procedure used for successful treatment of renal calculi. However, it is associated with various complications. We assessed the complications and their potential influencing factors in patients who had undergone PNL. In total, 1750 patients who had undergone PNL from November 2003 to June 2011 were evaluated retrospectively. PNL complications and possible contributing risk factors (age, sex, serum creatinine level, previous operations, hydronephrosis, calculi size, localization, opacity, surgeon's experience, accessed calyxes, number of accesses, and costal entries) were determined. Receiver operating characteristic (ROC) analysis was used to investigate the cutoff values of the data. Ideal cutoff value was determined by Youden's J statistic. All the demographic and clinical variables were examined using backward stepwise logistical regression analysis. Continuous variables were categorized with logistic regression analysis according to the cutoff values. Complications occurred in 396 (24.4%) patients who had undergone PNL. Hemorrhage requiring blood transfusion occurred in 221 (12.6%) patients, hemorrhage requiring arterial embolization occurred in 7 (0.4%) patients, perirenal hematoma occurred in 17 (0.97%) patients, hemo-pneumothorax occurred in 32 (1.8%) patients, and colon perforation occurred in 4 (0.22%) patients. Three patients (0.06%) died of severe urosepsis, and one patient (0.02%) died of severe bleeding. The calculus size, localization, access site, number of accesses, presence of staghorn stones, surgeon's experience, and duration of the operation significantly affected the complication risk. Our retrospective evaluation of this large patient series reveals that, PNL is a very effective treatment modality for kidney stones. However, although rare, serious complications including death can occur.

Staple-line bleeding and leakage are the most common serious complications of laparoscopic sleeve gastrectomy. The relationship between multiple stapler firings and higher risk of postoperative complications is well defined in colorectal surgery but has not been addressed in bariatric procedures so far. Identification of new factors such as "the numbers of stapler firings used during laparoscopic sleeve gastrectomy (LSG)" as a predictor for complications can lead to optimization of the patient care at bariatric centers. To determine the association between perioperative morbidity and the number of stapler firings during laparoscopic sleeve gastrectomy. This observational study was based on retrospective analysis of prospectively collected data in patients operated on for morbid obesity in a teaching hospital/tertiary referral center for general surgery. The patients who underwent LSG were analyzed in terms of the number of stapler firings used as a new potential risk predictor for postoperative complications after surgery, adjusting for other patient- and treatment-related factors. The study included 333 patients (209 women, 124 men, mean age: 40 ±11). During the first 30 days after surgery, complications were observed in 18 (5.41%) patients. Multivariate analysis showed that prolonging operative time increased morbidity (every minute, OR = 1.01; 95% CI: 1.00-1.02) and the complication rate increased with the number of stapler firings (every firing, OR = 1.91; 95% CI: 1.09-3.33; p = 0.023). Additional stapler firings above the usual number and a prolonged operation should alert a surgeon and the whole team about increased risk of postoperative complications.

Open treatment of pilon fractures is associated with wound healing complications. A traumatized, limited soft tissue envelope contributes to wound healing complications. Obese patients have larger soft tissue envelopes around the ankle, theoretically providing a greater area for energy distribution and more accommodation to implants. This led us to test 2 hypotheses: (1) ankle dimensions in obese patients are larger than in lean patients, and (2) the increased soft tissue envelope volume translates into fewer wound complications. A consecutive series of 176 pilon fractures treated from March 2002 to December 2007 were retrospectively reviewed. Inclusion criteria were adults who received a preoperative computed tomography (CT) scan and were treated with a staged protocol including plating. Patients with body mass index (BMI) >30 were compared to those with BMI <30 for CT-derived ankle dimensions and wound complications. Comorbidities were evaluated for their role as potential confounders. Thirty-one fractures in obese patients were compared to 83 in lean patients. The average ratio of bone area to soft tissue area at the tibial plafond was 0.35 for the obese group and 0.38 for the lean group (P=.012). There were 8 major wound-healing complications. Four occurred in the obese group (incidence 13%), and 4 in the lean group (incidence 5%) (P=.252). Ankle dimensions in clinically obese patients are larger than in lean patients. Obesity does not appear to be protective of wound-healing complications, but rather there is a trend toward the opposite. Copyright 2010, SLACK Incorporated.

To describe the ocular findings, visual impairment, and association of structural complications of uveitis with visual impairment in a cohort of survivors of Ebola virus disease (EVD) in Monrovia, Liberia. Retrospective, uncontrolled, cross-sectional study. Survivors of EVD who were evaluated in an ophthalmology clinic at Eternal Love Winning Africa (ELWA) Hospital in Monrovia, Liberia. A cohort of EVD survivors who underwent baseline ophthalmic evaluation at ELWA Hospital were retrospectively reviewed for demographic information, length of Ebola treatment unit (ETU) stay, visual acuity (VA), and ophthalmic examination findings. For patients with uveitis, disease activity (active vs. inactive) and grade of inflammation were recorded according to Standardization of Uveitis Nomenclature criteria. The level of VA impairment was categorized according to World Health Organization classification for VA impairment as follows: normal/mild, VA 20/70 or better; moderate, VA 20/70-20/200; severe, VA 20/200-20/400; blindness, VA <20/400. Visual acuity, length of ETU stay, and structural complications were compared between EVD survivors with and without uveitis. Structural complications associated with moderate VA impairment or poorer were analyzed. Frequency of ocular complications including uveitis and optic neuropathy in EVD survivors, level of VA impairment in EVD survivors with uveitis, and structural complications associated with VA impairment in EVD survivors. A total of 96 survivors of EVD were examined. A total of 21 patients developed an EVD-associated uveitis, and 3 patients developed an EVD-associated optic neuropathy. Visual acuity was blind (VA >20/400) in 38.5% of eyes with uveitis. Anatomic subtypes of uveitis included anterior, posterior, and panuveitis in 2, 13, and 6 patients, respectively. Examination findings associated with at least moderate visual impairment by World Health Organization criteria (VA <20/70) included keratic precipitates (P < 0.002), posterior synechiae (P < 0.002), vitritis (P < 0.005), and chorioretinal scars (P < 0.02). Survivors of EVD are at risk for uveitis, which may lead to secondary structural complications, visual impairment, and blindness. Eye care resources should be mobilized for EVD survivors in West Africa because of the frequency of this spectrum of disease complication and its potential for severe VA impairment and blindness.

Prosthetic valve thrombosis (PVT) is a potentially life-threatening complication of heart valve replacement. Early diagnosis is crucial for the prevention of significantly morbid and lethal complications. Cinefluoroscopy (CF) and echocardiography have been widely used for diagnosing PVT. In recent years, the role of CF has declined since the introduction of transesophageal echocardiography and the great improvements in ultrasound technology including real time three-dimensional imaging. Nevertheless, both echocardiography and CF provide different kinds of information on prosthesis function, and therefore they are considered as complementary and not alternative. In this review, we aimed to summarize the current status of CF and echocardiography in the diagnosis of PVT. © 2014, Wiley Periodicals, Inc.

The number of individuals with prediabetes is expected to grow substantially and estimated to globally affect 482 million people by 2040. Therefore, effective methods for diagnosing prediabetes will be required to reduce the risk of progressing to diabetes and its complications. The current biomarkers, glycated hemoglobin (HbA1c), fructosamine, and glycated albumin have limitations including moderate sensitivity and specificity and are inaccurate in certain clinical conditions. Therefore, identification of additional biomarkers is being explored recognizing that any single biomarker will also likely have inherent limitations. Therefore, combining several biomarkers may more precisely identify those at high risk for developing prediabetes and subsequent progression to diabetes. This review describes recently identified biomarkers and their potential utility for addressing the burgeoning epidemic of dysglycemic disorders. PMID:28860833

Anesthesia and airway management for removing pulmonary self-expanding metallic stents.

Doyle, D John; Abdelmalak, Basem; Machuzak, Michael; Gildea, Thomas R

2009-11-01

The use of bronchoscopically placed self-expanding metallic stents (SEMS) and silastic stents in patients suffering from tracheobronchial stenosis or similar problems has proven to be an important clinical option. When complications occur, it may be necessary to remove the device. Removal of a SEMS is usually performed during general anesthesia with muscle relaxation and positive pressure ventilation, often using total intravenous anesthesia. Airway management depends on stent type and location. Intubating patients' tracheas with a tracheal stent requires special caution, as it risks damaging tissue and dislodging the stent distally. Potential complications with removal include tracheal disruption, retained stent pieces, mucosal tears, re-obstruction requiring new stent placement, the need for postoperative ventilation, pneumothorax, damage to the pulmonary artery, and death.

Dermal fillers have been increasingly used in minimally invasive facial esthetic procedures. This widespread use has led to a rise in reports of associated complications. The aim of this expert consensus report is to describe potential adverse events associated with dermal fillers and to provide guidance on their treatment and avoidance. A multidisciplinary group of experts in esthetic treatments convened to discuss the management of the complications associated with dermal fillers use. A search was performed for English, French, and Spanish language articles in MEDLINE, the Cochrane Database, and Google Scholar using the search terms "complications" OR "soft filler complications" OR "injectable complications" AND "dermal fillers" AND "Therapy". An initial document was drafted by the Coordinating Committee, and it was reviewed and modified by the experts, until a final text was agreed upon and validated. The panel addressed consensus recommendations about the classification of filler complications according to the time of onset and about the clinical management of different complications including bruising, swelling, edema, infections, lumps and bumps, skin discoloration, and biofilm formation. Special attention was paid to vascular compromise and retinal artery occlusion. Clinicians should be fully aware of the signs and symptoms related to complications and be prepared to confidently treat them. Establishing action protocols for emergencies, with agents readily available in the office, would reduce the severity of adverse outcomes associated with injection of hyaluronic acid fillers in the cosmetic setting. This document seeks to lay down a set of recommendations and to identify key issues that may be useful for clinicians who are starting to use dermal fillers. Additionally, this document provides a better understanding about the diagnoses and management of complications if they do occur. This journal requires that authors assign a level of evidence to each article.

Volar plating of unstable distal radius fractures (DRF) has become the favoured treatment. The complication rates vary from 3 to 36%. The purpose of the study was to estimate the complication rate of volar plating of DRF and its association with AO/OTA fracture type, surgeon experience and type of volar plate. Retrospectively, all patients treated with volar plating of a DRF between February 2009 and June 2013 at Aarhus University Hospital, Denmark were included. AO/OTA fracture type, surgeon experience (1st year, 2nd-5th year resident or consultant), type of plate (VariAx ® , Acu-Loc ® ) and complications were extracted from the electronic medical records. Complications were categorized as carpal tunnel syndrome, other sensibility issues, tendon complications including irritation and rupture, deep infections, complex regional pain syndrome and unidentified DRUJ or scapholunar problems. Reoperations including hardware removal were also charted. 576 patients with a median age of 63 years (min: 15; max: 87) were included. 78% were female and the mean observation time was 3.2 years (min: 2.0; max: 5.4). 78% (n=451) of the patients were treated with VariAx ® and 22% (n=125) with Acu-Loc ® . The overall complication rate was 14.6% (95% CI 11.8-17.7) including carpal tunnel syndrome or change in sensibility in 5.2% and tendon complications in 4.7%. Five flexor tendon ruptures and 12 extensor tendon ruptures were observed. The reoperation rate was 10.4% including 41 cases of hardware removal. A statistically significant association between AO/OTA fracture type C and complications was found. No statistically significant association between complication rate and surgeon experience and type of plate was observed. The majority of DRF patients treated with a volar plate suffer no complications. However, the overall complication rate of 14.6% is substantial. Intra-articular fractures, e.g. AO/OTA-type 23C1-3, had significantly higher complication rates. Neither surgeon experience, nor type of volar plate was able to predict complications.

Hannan, Jean

2015-06-01

Complementary and alternative healthcare practices have increased substantially in the United States especially with low-income ethnic minority mothers. These mothers often have provider mistrust, language barriers, differing health belief systems, and as a result are less likely to seek preventive health screening, access healthcare services, and use alternative remedies for their infants and children that are potentially harmful or lethal. Therefore, the purpose of this article is to examine healthcare beliefs, commonly used alternative healthcare practices, and their potential complications for infants and children. A search of CINAHL and PubMed (1980-2012) was conducted using the following terms: alternative healthcare practice, mothers' health beliefs, cultural health beliefs, folk remedies, and infant health practices. Given the changing U.S. population and an increasing immigrant population, examining alternative healthcare practices mothers use for their infants and children is especially important for providers in addressing healthcare for this group. The use of alternative healthcare practices is rarely discussed by parents with healthcare providers for fear of disapproval. When interviewing ethnic minority mothers and caregivers questions should include the use of alternative healthcare practices for infants and children and information regarding the potential dangers should be provided to them. ©2014 American Association of Nurse Practitioners.

Infections and complex wounds after ventricular assist device (VAD) placement can result in significant morbidity and mortality. The purpose of this study was to evaluate complex wound management in the VAD patient, and to describe a treatment protocol for these challenging and potentially mortal complications. A retrospective study was performed to examine all patients who underwent continuous flow, second-generation VAD placement at the Hospital of the University of Pennsylvania between March 2008 and April 2013. Overall, 150 VADs were placed, with 12 (8%) patients requiring 15 operative interventions by the plastic surgery services. The most common indication for operative intervention was a complicated wound with VAD exposure (5/12, 41.7%). All patients underwent aggressive operative debridement, and 11/12 (92%) underwent vascularized soft tissue coverage. Flaps commonly utilized included rectus abdominus myocutaneous (n = 4), rectus abdominus muscle (n = 4), pectoralis major (n = 3), and omentum (n = 3). Three patients experienced complications which required a return to the operating room, including 1 flap loss, 1 hematoma, and 1 wound dehiscence requiring further soft tissue coverage. Salvage was achieved, yet a 50% mortality rate in follow-up was noted. Complex wound management in VAD patients can be achieved with aggressive debridement and vascularized soft tissue coverage, most commonly utilizing well-vascularized rectus abdominus muscle or omental flaps. Plastic surgeons should be familiar with the armamentarium at their disposal when approaching these challenging cases as VAD wound complications stand to become an increasingly prevalent issue.

Human immunodeficiency virus (HIV)-related facial lipoatrophy is a devastating adverse effect of antiretroviral therapy. At this time, the most viable treatment option is cosmetic surgery with synthetic fillers. Bio-Alcamid has many advantages over other fillers, and has become widely used. The objective of this study was to determine the incidence rate of infectious complications associated with Bio-Alcamid facial filler in patients with HIV-related facial lipoatrophy (FLA). This retrospective study identified patients who had received treatment with Bio-Alcamid, and reviewed their long-term outcomes. Two hundred sixty-seven patients with Bio-Alcamid were reviewed. Infectious complications were documented in 56 (19%) patients. The incidence rate of infection was 0.07 per patient-year of follow-up. Among patients with infections, the median time from first Bio-Alcamid treatment to infection was 32 months (interquartile range, 21-42). We did not find an association between the development of infection and the level of immune suppression by HIV. Surgical drainage in addition to antibiotics was required for the majority of patients. Potential risk factors for infection include severity of FLA and a preceding history of facial manipulation, including Bio-Alcamid touch-up treatments, cosmetic surgery, facial trauma, and dental work. Bio-Alcamid treatment of HIV-related FLA was associated with a high rate of infectious complications, often presenting years after treatment. Antibiotic prophylaxis should be considered in patients with Bio-Alcamid prior to dental work or facial manipulation.

Diagnoses of Type 1 Diabetes Mellitus (T1DM) in Europe appear to be on the rise. Therefore it is imperative that researchers understand the potential impact that increases in prevalence could have on the affected individuals as well as on society as a whole. Accordingly this study examined the humanistic and economic burden of T1DM in patients relative to those without the condition across a number of health outcomes including health status, work productivity loss, activity impairment, and healthcare resource use. Survey data from a large, representative sample of EU adults (The EU National Health and Wellness Survey) were examined. Results suggest that overall burden is higher for those diagnosed with T1DM than respondents without diabetes and that burden increases as complications associated with T1DM increase. Taken together, these results suggest that treatment strategies for T1DM should balance clinical, humanistic, and economic burden and patients should be educated on the role of complications in disease outcomes.

Background: Flexor tenolysis surgery for flexor digitorum profundus and superficialis adhesions is a common procedure performed by hand surgeons. Releasing these adhered tendons can greatly improve hand function and improve quality of life. Recent evidence, however, has shown that the outcomes of tenolysis surgeries are often suboptimal and can result in relapsing adhesions or even tendon ruptures. Methods: This article describes a new technique with potential for reduced complication rates: The Fine Wire Technique for Flexor Tenolysis (FWT). Results: Following FWT, the patient detailed in this article had an excellent recovery of function and no complications: including tendon rupture, infection, hematomas, or any other complications. She reported a major improvement from her preoperative functionality and continues to have this level of success. The wire’s thinness allows for a swift tenolysis. Conclusions: The FWT is a new option available to the hand surgeon associated with good functional results. The wire is readily available to the clinician and is also inexpensive. PMID:29263961

Current understanding of the role of oxidative stress in ocular inflammatory diseases indicates that antioxidant therapy may be important to optimize the treatment. Recently investigated antioxidant therapies for ocular inflammatory diseases include various vitamins, plant products and reactive oxygen species scavengers. Oxidative stress plays a causative role in both non-infectious and infectious uveitis complications, and novel strategies to diminish tissue damage and dysfunction with antioxidant therapy may ameliorate visual complications. Preclinical studies with experimental animals and cell culture demonstrate significance of anti-inflammatory effects of a number of promising antioxidant agents. Many of these antioxidants are under clinical trial for various inflammatory diseases other than uveitis such as cardiovascular, rheumatoid arthritis and cancer. Well planned interventional clinical studies of the ocular inflammation will be necessary to sufficiently investigate the potential medical benefits of antioxidant therapies for uveitis. This review summarizes the recent investigation of novel antioxidant agents for ocular inflammation, with selected studies focused on uveitis. PMID:21182473

Acute respiratory distress syndrome and acute renal failure from Plasmodium ovale infection with fatal outcome

PubMed Central

2013-01-01

Background Plasmodium ovale is one of the causative agents of human malaria. Plasmodium ovale infection has long been thought to be non-fatal. Due to its lower morbidity, P. ovale receives little attention in malaria research. Methods Two Malaysians went to Nigeria for two weeks. After returning to Malaysia, they fell sick and were admitted to different hospitals. Plasmodium ovale parasites were identified from blood smears of these patients. The species identification was further confirmed with nested PCR. One of them was successfully treated with no incident of relapse within 12-month medical follow-up. The other patient came down with malaria-induced respiratory complication during the course of treatment. Although parasites were cleared off the circulation, the patient’s condition worsened. He succumbed to multiple complications including acute respiratory distress syndrome and acute renal failure. Results Sequencing of the malaria parasite DNA from both cases, followed by multiple sequence alignment and phylogenetic tree construction suggested that the causative agent for both malaria cases was P. ovale curtisi. Discussion In this report, the differences between both cases were discussed, and the potential capability of P. ovale in causing severe complications and death as seen in this case report was highlighted. Conclusion Plasmodium ovale is potentially capable of causing severe complications, if not death. Complete travel and clinical history of malaria patient are vital for successful diagnoses and treatment. Monitoring of respiratory and renal function of malaria patients, regardless of the species of malaria parasites involved is crucial during the course of hospital admission. PMID:24180319

Intensive nutritional support can reduce the catabolic response, improve protein synthesis, and promote liver regeneration. This study examined whether postoperative peripheral parenteral nutrition may improve recovery and reduce the length of hospital stay in right lobe liver donors. In this retrospective study, we enrolled liver donors with residual liver volume < 50%. Donors were classified into 2 groups: donors who received (n = 44) or did not receive (n = 40) postoperative peripheral parenteral nutrition. Liver function tests included alanine aminotransferase and total bilirubin levels, and postoperative complications included pleural effusion, atelectasis, and wound complications. Hospital length of stay was included as a potential risk factor for the evaluation of the effect of postoperative peripheral parenteral nutrition on recovery of right lobe liver donors. Male sex (β, 22.04; 95% confidence interval: 6.22 - 37.86) was a significant predictor of changes in postoperative alanine aminotransferase level. Male sex (β, 0.045; 95% confidence interval: 0.16 - 37.86) and receipt of peripheral parenteral nutrition (β, -0.045; 95% confidence interval: -0.72 - 0.17) were significant predictors of changes in total bilirubin level. Postoperative atelectasis (P < .001), pleural effusion (P < .011), and total complications (P = .015) had significantly lower incidence in the peripheral parenteral nutrition than control group. Multivariate logistic regression showed that recipients of peripheral parenteral nutrition (odds ratio, 0.161; 95% confidence interval: 0.043 - 0.598) and age (odds ratio, 0.870; 95% confidence interval: 0.782 - 0.968) were significant preoperative risk factors for postoperative complications. Postoperative peripheral parenteral nutrition is associated with a lower incidence of pleural effusion and atelectasis, a more rapid recovery of hyperbilirubinemia, and shorter length of stay in right lobe liver donors.

The expanding diabetes epidemic worldwide could have potentially devastating effects on the development of healthcare systems and economies in emerging countries, both in terms of direct health care costs and loss of working time and disability. This study aims to review evidence on the burden, expenditure, complications, treatment, and outcomes of diabetes in Indonesia and its implications on the current health system developments. We conducted a comprehensive literature review together with a review of unpublished data from the Ministry of Health and a public health insurer (Askes). Studies presenting evidence on prevalence, incidence, mortality, costs, complications and cost of complications, treatment, and outcomes were included in the analysis. A limited number of international, national and local studies on the burden and cost of diabetes in Indonesia were identified. National survey data suggests that in 2007 the prevalence of diabetes was 5.7%, of which more than 70% of cases were undiagnosed. This estimate hides large intracountry variation. There was very limited data available on direct costs and no data on indirect costs. The most commonly-identified complication was diabetic neuropathy. There were a number of limitations in the data retrieved including the paucity of data representative at the national level, lack of a clear reference date, lack of data from primary care, and lack of data from certain regions of the country. If left unaddressed, the growing prevalence of diabetes in the country will pose a tremendous challenge to the Indonesian healthcare system, particularly in view of the Government's 2010 mandate to achieve universal health coverage by 2014. Essential steps to address this issue would include: placing diabetes and non-communicable diseases high on the Government agenda and creating a national plan; identifying disparities and priority areas for Indonesia; developing a framework for coordinated actions between all relevant stakeholders.

To determine the relationship between body mass index (BMI) and risk for specific complications from transtemporal cerebellopontine angle (CPA) surgery for nonmalignant disease. Case series with chart review. Tertiary-care academic hospital. Retrospective review of 134 consecutive patients undergoing transtemporal cerebellopontine angle surgery for nonmalignant disease from 2009 to 2011. Data were collected regarding demographics, body mass index, intraoperative details, hospital stay, and complications including cerebrospinal fluid leak, wound complications, and brachial plexopathy. One hundred thirty-four patients were analyzed with a mean preoperative body mass index of 28.58. Statistical analysis demonstrated a significant difference in body mass index between patients with a postoperative cerebrospinal fluid leak and those without (P = .04), as well as a similar significant difference between those experiencing postoperative brachial plexopathy and those with no such complication (P = .03). Logistical regression analysis confirmed that body mass index is significant in predicting both postoperative cerebrospinal fluid leak (P = .004; odds ratio, 1.10) and brachial plexopathy (P = .04; odds ratio, 1.07). Elevated body mass index was not significant in predicting wound complications or increased hospital stay beyond postoperative day 3. Risk of cerebrospinal fluid leak and brachial plexopathy is increased in patients with elevated body mass index undergoing surgery of the cerebellopontine angle. Consideration should be given to preoperative optimization via dietary and lifestyle modifications as well as intraoperative somatosensory evoked potential monitoring of the brachial plexus to decrease these risks.

Safely combining abdominoplasty with aggressive abdominal liposuction based on perforator vessels: technique and a review of 300 consecutive cases.

PubMed

Smith, Lane F; Smith, Lane F

2015-05-01

There continues to be controversy about performing abdominoplasty concurrently with abdominal liposuction. The concern is that liposuction on the already vascularly compromised abdominal flap will lead to increased complications and flap necrosis. The central abdomen is supplied by the epigastric system. If perforator vessels from this system are spared, the blood supply to the abdomen can be spared and liposuction should be able to be safely performed on the elevated abdominal flap. The purpose of this study was to evaluate the safety of abdominoplasty with concurrent abdominal liposuction when a perforator vessel is spared. A standard abdominoplasty was performed, sparing one or two perforator vessels from the deep superior epigastric artery system. A retrospective chart review of 300 consecutive patients who underwent abdominoplasty surgery combined with concurrent abdominal liposuction was performed. Complications, total volume of abdominal liposuction, and results were reviewed. The overall complication rate was 17.3 percent (52 patients). Sixteen percent (48 patients) suffered minor complications and 1.3 percent (four patients) suffered major complications. Abdominoplasty can be combined safely with concurrent abdominal liposuction when a perforator vessel is spared. The combination of concurrent liposuction with abdominoplasty showed no increase in complication rates when a perforator vessel was spared. The perforator vessels are located consistently in a 2-cm radius located 4 cm from the midline and 6 cm from the subcostal margin. The potential advantages of abdominoplasty with concurrent liposuction include a better postoperative cosmetic result. Therapeutic, IV.

Percutaneous nephrolithotomy (PCNL) is a standard management option for complex and large renal calculi. In children, there is some concern over potential perioperative complications. We reviewed our 10 years of experience of PCNL in children and present our data. Data for paediatric patients who underwent PCNL at our centre in the last decade were retrieved. PCNL was performed in standard prone position under fluoroscopic guidance. Patient characteristics, outcomes and complications were reviewed. Complications were graded according to the modified Clavien system. A comparison was also made between supracostal and infracostal accesses. 95 children underwent PCNL in our institute in the last decade. 7 patients had bilateral PCNL. The most common presentation was flank pain (85%). 83% patients were stone-free after first PCNL and overall 94% were stone free after second-look PCNL and auxillary procedures. 6 cases had clinically insignificant residual fragments. Supracostal puncture was performed in 32 cases. Complications were higher in the supracostal puncture group (16 (50%)) and included fever in 11, sepsis in 2 and hydrothorax in 3 patients. There were 7 (10%) complications in the infracostal group: fever in 5 and perinephric collection in 2 patients. 16 patients had grade 1, 9 had grade 2 and another 2 cases developed grade 3 complications. PCNL is a safe and effective procedure in children. It enables excellent stone clearance with minimal number of interventions. Copyright © 2013 Journal of Pediatric Urology Company.

With recent insight into the development of dietary supplements and functional foods, search of effective phytochemical compounds and their mechanisms involved in prevention and management of diabetes and its complications are now being assessed. Cinnamic acid and its derivatives occur naturally in high levels of plant-based foods. Among various biological activities, cinnamic acid and its derivatives are associated with a beneficial influence on diabetes and its complications. The aim of the review is to summarize the potential mechanisms of these compounds for prevention and management of diabetes and its complications. Based on several in vitro studies and animal models, cinnamic acid and its derivatives act on different mechanism of actions, including stimulation of insulin secretion, improvement of pancreatic β-cell functionality, inhibition of hepatic gluconeogenesis, enhanced glucose uptake, increased insulin signaling pathway, delay of carbohydrate digestion and glucose absorption, and inhibition of protein glycation and insulin fibrillation. However, due to the limited intestinal absorption being a result of low bioavailability of cinnamic acid and its derivatives, current improvement efforts with entrapping into solid and liquid particles are highlighted. Further human clinical studies are needed to clarify the effects of cinnamic acid and its derivatives in diabetic patients.

The refeeding syndrome is a potentially lethal complication of refeeding in patients who are severely malnourished from whatever cause. Too rapid refeeding, particularly with carbohydrate may precipitate a number of metabolic and pathophysiological complications, which may adversely affect the cardiac, respiratory, haematological, hepatic and neuromuscular systems leading to clinical complications and even death. We aimed to review the development of the refeeding syndrome in a variety of situations and, from this and the literature, devise guidelines to prevent and treat the condition. We report seven cases illustrating different aspects of the refeeding syndrome and the measures used to treat it. The specific complications encountered, their physiological mechanisms, identification of patients at risk, and prevention and treatment are discussed. Each case developed one or more of the features of the refeeding syndrome including deficiencies and low plasma levels of potassium, phosphate, magnesium and thiamine combined with salt and water retention. These responded to specific interventions. In most cases, these abnormalities could have been anticipated and prevented. The main features of the refeeding syndrome are described with a protocol to anticipate, prevent and treat the condition in adults.

A causal link has long been described between estrogen and systemic lupus erythematosus activity. Contraceptive and pregnancy management is now common for lupus patients, but pregnancy continues to be associated with higher maternal and fetal mortality/morbidity in systemic lupus erythematosus patients than among the general population. Potential complications include lupus flares, obstetric complications (fetal loss, in utero growth retardation, premature birth) and neonatal lupus syndrome. Association with antiphospholipid antibodies or antiphospholipid syndrome increases the risk of obstetric complications. Anti-SSA and/or anti-SSB antibodies put fetuses at risk for neonatal lupus. Improving the outcome of such pregnancies depends upon optimal systematic planning of pregnancy at a preconception counseling visit coupled with a multidisciplinary approach. Absence of lupus activity, use of appropriate medication during pregnancy based on the patient's medical history and risk factors, and regular monitoring constitute the best tools for achieving a favorable outcome in such high-risk pregnancies. The aim of this review is to provide an update on the management of contraception and pregnancy in systemic lupus erythematosus, cutaneous lupus and/or antiphospholipid syndrome in order to reduce the risk of complications and to ensure the best maternal and fetal prognosis.

The implications of childhood obesity on pediatric trauma outcomes are not clearly established. Anthropomorphic data were recently added to the National Trauma Data Bank (NTDB) Research Datasets, enabling a large, multicenter evaluation of the effect of obesity on pediatric trauma patients. Children ages 2 to 19years who required hospitalization for traumatic injury were identified in the 2013-2014 NTDB Research Datasets. Age and gender-specific body mass indices (BMI) were calculated. Outcomes included injury patterns, operative procedures, complications, and hospital utilization parameters. Data from 149,817 pediatric patients were analyzed; higher BMI percentiles were associated with significantly more extremity injuries, and fewer injuries to the head, abdomen, thorax and spine (p values <0.001). On multivariable analysis, higher BMI percentiles were associated with significantly increased likelihood of death, deep venous thrombosis, pulmonary embolus and pneumonia; although there was no difference in risk of overall complications. Obese children also had significantly longer lengths of stay and more frequent ventilator requirement. Among children admitted after trauma, increased BMI percentile is associated with increased risk of death and potentially preventable complications. These findings suggest that obese children may require different management than nonobese counterparts to prevent complications. Level III; prognosis study. Copyright © 2017 Elsevier Inc.

New treatments for levodopa-induced motor complications.

2015-09-15

Levodopa (l-dopa)-induced motor complications, including motor fluctuations and dyskinesia, affect almost all patients with Parkinson's disease (PD) at some point during the disease course, with relevant implications in global health status. Various dopaminergic and nondopaminergic pharmacological approaches as well as more invasive strategies including devices and functional surgery are available to manage such complications. In spite of undisputable improvements during the last decades, many patients remain significantly disabled, and a fully satisfying management of l-dopa-induced motor complications is still an important unmet need of PD therapy. This article reviews the recent trial results published from 2013 to April 2015 about pharmacological and nonpharmacological interventions to treat motor complications. Randomized controlled trials conducted in patients suffering from already established complications showed that new levodopa (l-dopa) formulations such as intrajejunal l-dopa-carbidopa infusion and bilayered extended-release l-dopa-carbidopa (IPX066) can improve motor fluctuations. Positive results were also obtained with a new monoamine oxidase B (MAO-B) inhibitor (safinamide) and a catechol-O-methyltransferase COMT inhibitor (opicapone). Pilot data suggest that new formulations of dopamine agonists (inhaled apomorphine) are also of potential interest. The development of novel nondopaminergic adenosine A2A antagonists (istradefylline, preladenant, and tozadenant) to treat motor fluctuations showed conflicting results in phase 2 and phase 3 trials. For dyskinesia, trials with new amantadine extended-release formulations confirmed the interest of the glutamatergic N-methyl-d-aspartate (NMDA) antagonist approach. Positive pilot antidyskinetic effects were also recently reported using serotonin agents such as eltoprazine and glutamate mGluR5 modulators such as mavoglurant. However, the translation to clinical practice of such innovative concepts remains challenging, because subsequent phase 2 trials conducted to confirm the antidyskynetic effects of mavoglurant failed, leading to the interruption of the development of this compound for this indication. © 2015 International Parkinson and Movement Disorder Society.

The best time for definitive orthopaedic care is often unclear in patients with multiple injuries. The objective of this study was make a prospective assessment of the safety of our early appropriate care (EAC) strategy and to evaluate the potential benefit of additional laboratory data to determine readiness for surgery. A cohort of 335 patients with fractures of the pelvis, acetabulum, femur, or spine were included. Patients underwent definitive fixation within 36 hours if one of the following three parameters were met: lactate < 4.0 mmol/L; pH ≥ 7.25; or base excess (BE) ≥ -5.5 mmol/L. If all three parameters were met, resuscitation was designated full protocol resuscitation (FPR). If less than all three parameters were met, it was designated an incomplete protocol resuscitation (IPR). Complications were assessed by an independent adjudication committee and included infection; sepsis; PE/DVT; organ failure; pneumonia, and acute respiratory distress syndrome (ARDS). In total, 66 patients (19.7%) developed 90 complications. An historical cohort of 1441 patients had a complication rate of 22.1%. The complication rate for patients with only one EAC parameter at the point of protocol was 34.3%, which was higher than other groups (p = 0.041). Patients who had IPR did not have significantly more complications (31.8%) than those who had FPR (22.6%; p = 0.078). Regression analysis showed male gender and injury severity score to be independent predictors of complications. This study highlights important trends in the IPR and FPR groups, suggesting that differences in resuscitation parameters may guide care in certain patients; further study is, however, required. We advocate the use of the existing protocol, while research is continued for high-risk subgroups.

Treatment costs of induced abortion complications can consume a substantial amount of hospital resources. This use of hospitals scarce resources to treat induced abortion complications may affect hospitals' capacities to deliver other health care services. In spite of the importance of studying the burden of the treatment of induced abortion complications, few studies have been conducted to document the costs of treating abortion complications in Burkina Faso. Our objective was to estimate the costs of six abortion complications including incomplete abortion, hemorrhage, shock, infection/sepsis, cervix or vagina laceration, and uterus perforation treated in two public referral hospital facilities in Ouagadougou and the cost saving of providing safe abortion care services. The distribution of abortion-related complications was assessed through a review of postabortion care-registers combined with interviews with key informants in maternity wards and in hospital facilities. Two structured questionnaires were used for data collection following the perspective of the hospital. The first questionnaire collected information on the units and the unit costs of drugs and medical supplies used in the treatment of each complication. The second questionnaire gathered information on salaries and overhead expenses. All data were entered in a spreadsheet designed for studying abortion, and analyses were performed on Excel 2007. Across six types of abortion complications, the mean cost per patient was USD45.86. The total cost to these two public referral hospital facilities for treating the complications of abortion was USD22,472.53 in 2010 equivalent to USD24,466.21 in 2015. Provision of safe abortion care services to women who suffered from complications of unsafe induced abortion and who received care in these public hospitals would only have cost USD2,694, giving potential savings of more than USD19,778.53 in that year. The treatment of the complications of abortion consumes a significant proportion (up to USD22,472.53) of the two public hospitals resources in Burkina Faso. Safe abortion care services may represent a cost beneficial alternative, as it may have saved USD19,778.53 in 2010.

2012-10-01

The ethics of diagnosis and management of fetal genetic disorders are particularly controversial because of the contested status of the fetus and perceptions of genetics. An additional complicating factor is the potential conflict between mother and fetus. Ethical issues in diagnosis include the nature and purpose of the diagnosis itself, and management of the information. Management of the disorder includes issues of termination as an option, and the emerging field of fetal gene therapy with associated issues of somatic versus germ-line interventions.

Chronic obstructive pulmonary disease (COPD) is a common and preventable lung disease that affects millions of people in the United States. Sleep disorders including obstructive sleep apnea (OSA) are also common. It is not surprising that many people with COPD also suffer from OSA. This relationship, however, puts people at risk for more nocturnal desaturations and potential complications related to this, including pulmonary hypertension and heart rhythm disturbances. This update focuses on the physiology of sleep disturbances in COPD as well as the clinical implications of OSA in COPD. PMID:24748786

Wound Healing Complications Following Guided Bone Regeneration for Ridge Augmentation: A Systematic Review and Meta-Analysis.

Lim, Glendale; Lin, Guo-Hao; Monje, Alberto; Chan, Hsun-Liang; Wang, Hom-Lay

The rate of developing soft tissue complications that accompany guided bone regeneration (GBR) procedures varies widely, from 0% to 45%. The present review was conducted to investigate the rate for resorbable versus nonresorbable membranes and the timing of soft tissue complications. Electronic and manual literature searches were conducted by two independent reviewers using several databases, including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Cochrane Oral Health Group Trials Register, for articles published through July 2015, with no language restriction. Articles were included if they were clinical trials aimed at demonstrating the incidence of soft tissue complications following GBR procedures. Overall, 21 and 15 articles were included in the qualitative and quantitative synthesis, respectively. The weighted complication rate of the overall soft tissue complications, including membrane exposure, soft tissue dehiscence, and acute infection/abscess, into the calculation was 16.8% (95% CI = 10.6% to 25.4%). When considering the complication rate based on membrane type used, resorbable membrane was associated with a weighted complication rate of 18.3% (95% CI: 10.4% to 30.4%) and nonresorbable membrane with a rate of 17.6% (95% CI: 10.0% to 29.3%). Moreover, soft tissue lesions were reported as early as 1 week and as late as 6 months based on the included studies. Soft tissue complications after GBR are common (16.8%). Membrane type did not appear to significantly affect the complication rate, based on the limited number of data retrieved in this study. Technique sensitivity (ie, soft tissue management) may still be regarded as the main component to avoid soft tissue complications and, hence, to influence the success of bone regenerative therapy.

Coprescribing proton-pump inhibitors with nonsteroidal anti-inflammatory drugs: risks versus benefits

Nonsteroidal anti-inflammatory drugs (NSAIDs) are often coadministered with proton-pump inhibitors (PPIs) to reduce NSAID-induced gastrointestinal (GI) adverse events. This coadministration is generally regarded as safe, and is included in many of the guidelines on NSAID prescription. However, recent evidence indicates that the GI risks associated with NSAIDs can be potentiated when they are combined with PPIs. This review discusses the GI effects and complications of NSAIDs and how PPIs may potentiate these effects, options for prevention of GI side effects, and appropriate use of PPIs in combination with NSAIDs.

With improvements in PET/CT and PET/MRI over the last decade, as well as increased understanding of the pathophysiology of musculoskeletal diseases, there is an emerging potential for PET as a primary or complementary modality in the management of rheumatologic and orthopedic conditions. We discuss the role of PET/CT and PET/MRI in nononcologic musculoskeletal disorders, including inflammatory and infectious conditions and postoperative complications. There is great potential for an increased role for PET to serve as a primary or complementary modality in the management of orthopedic and rheumatologic disorders.

Motor complications are a consequence of chronic treatment of Parkinson’s disease (PD) and include motor fluctuations (wearing-off phenomenon) and levodopa-induced dyskinesia. Both can have a significant impact on functionality and quality of life and thus proper recognition and management is essential. The phenomenology and temporal relationship of motor complications to the schedule of levodopa dosing can be helpful in characterizing them. There are several therapeutic approaches to motor complications, including pharmacological and surgical options. The current review summarizes the different types of motor complications according to phenomenology and the currently available medical treatments, including ongoing trials for management of this condition.

To assess the occurrence of severe maternal complications owing to postpartum hemorrhage (PPH) and its associated factors. A secondary analysis of data from a multicenter cross-sectional prospective surveillance study included 9555 cases of severe maternal morbidity at 27 centers in Brazil between July 2009 and June 2010. Complications of PPH, conditions of severity management, and sociodemographic and obstetric characteristics were assessed. Factors independently associated with severe maternal outcome (SMO) were identified using multiple regression analysis. Overall, 1192 (12.5%) of the 9555 women experienced complications owing to PPH (981 had potentially life-threatening conditions, 181 maternal near miss, and 30 had died). The SMO ratio was 2.6 per 1000 live births among women with PPH and 8.5 per 1000 live births among women with other complications. Women with PPH had a higher risk of blood transfusion and return to the operating theater than did those with complications from other causes. Maternal age, length of pregnancy, previous uterine scar, and cesarean delivery were the main factors associated with an increased risk of SMO secondary to PPH. PPH frequently leads to severe maternal morbidity. A surveillance system can identify the main causes of morbidity and could help to improve care, especially among women identified as being at high risk of PPH.

Henry, Brice; Lacroix, Valérie; Pirotte, Thierry; Docquier, Pierre-Louis

2018-01-01

Minimally invasive procedure for the treatment of pectus excavatum as described by Nuss has been used from 1987. The bar initially introduced blindly is now introduced under thoracoscopic control to increase safety of the procedure. It is usually removed two to three years after its insertion in a one-day procedure. Complications of the bar removal are rare but potentially serious. We report the case of a serious complication which occurred immediately after the Nuss bar removal. A 15-year-old boy underwent a Nuss procedure for a severe pectus excavatum without relevant complication. The bar has been removed two years after its insertion in a minimally invasive procedure. Unfortunately, he developed in the immediate postoperative period a hemopneumothorax due to a right middle lobe laceration which required a middle lobectomy by thoracotomy for hemostasis. Lesions of intrathoracic organs are a rare but potentially serious complication of the removal of the Nuss bar. We now propose to perform this procedure under thoracoscopic control to avoid it. In our experience, adhesions between the bar and the pleura are always present, and those with potential risk for bleeding or inducing intrathoracic organ lesions are suppressed prior to the bar removal.

Nocebo phenomena in medicine: their relevance in everyday clinical practice.

PubMed

Häuser, Winfried; Hansen, Ernil; Enck, Paul

2012-06-01

Nocebo phenomena are common in clinical practice and have recently become a popular topic of research and discussion among basic scientists, clinicians, and ethicists. We selectively searched the PubMed database for articles published up to December 2011 that contained the key words "nocebo" or "nocebo effect." By definition, a nocebo effect is the induction of a symptom perceived as negative by sham treatment and/or by the suggestion of negative expectations. A nocebo response is a negative symptom induced by the patient's own negative expectations and/or by negative suggestions from clinical staff in the absence of any treatment. The underlying mechanisms include learning by Pavlovian conditioning and reaction to expectations induced by verbal information or suggestion. Nocebo responses may come about through unintentional negative suggestion on the part of physicians and nurses. Information about possible complications and negative expectations on the patient's part increases the likelihood of adverse effects. Adverse events under treatment with medications sometimes come about by a nocebo effect. Physicians face an ethical dilemma, as they are required not just to inform patients of the potential complications of treatment, but also to minimize the likelihood of these complications, i.e., to avoid inducing them through the potential nocebo effect of thorough patient information. Possible ways out of the dilemma include emphasizing the fact that the proposed treatment is usually well tolerated, or else getting the patient's permission to inform less than fully about its possible side effects. Communication training in medical school, residency training, and continuing medical education would be desirable so that physicians can better exploit the power of words to patients' benefit, rather than their detriment.

Complex surgical procedures such as esophagectomy and gastrectomy for cancer are associated with substantial morbidity and mortality. The purpose of this study was to evaluate trends in postoperative morbidity, mortality, and associated failure-to-rescue (FTR), in patients who underwent a potentially curative resection for esophageal or gastric cancer in the Netherlands, and to investigate differences between the two groups. All patients with esophageal or gastric cancer who underwent a potentially curative resection, registered in the Dutch Upper GI Cancer Audit (DUCA) between 2011 and 2014, were included. Primary outcomes were (major) postoperative complications, postoperative mortality and FTR. To investigate groups' effect on the outcomes of interest a mixed model was used. Overall, 2644 patients with esophageal cancer and 1584 patients with gastric cancer were included in this study. In patients with gastric cancer, postoperative mortality (7.7% in 2011 vs. 3.8% in 2014) and FTR (38% in 2011 and 19% in 2014) decreased significantly over the years. The adjusted risk of developing a major postoperative complication was lower (OR 0.54; 95% CI 0.42-0.70), but the risk of FTR was higher (OR 1.85; 95% CI 1.05-3.27) in patients with gastric cancer compared to patients with esophageal cancer. Once a postoperative complication occurred, patients with gastric cancer were more likely to die compared to patients with esophageal cancer. Underlying mechanisms like patient selection, and differences in structure and organization of care should be investigated. Next to morbidity and mortality, failure-to-rescue should be considered as an important outcome measure after esophagogastric cancer resections.

Maternal nutrition among women from Sub-Saharan Africa, with a focus on Nigeria, and potential implications for pregnancy outcomes among immigrant populations in developed countries.

PubMed

Lindsay, K L; Gibney, E R; McAuliffe, F M

2012-12-01

Pregnant women in countries of Sub-Saharan Africa (SSA) are at risk of poor nutritional status and adverse outcomes as a result of poverty, food insecurity, sub-optimal healthcare facilities, frequent infections and frequent pregnancies. Studies from Nigeria, for example, have revealed a high prevalence of both under- and over-nutrition, as well as nutrient deficiencies, including iron, folate, vitamin D and vitamin A. Subsequently, obstetric complications, including hypertension, anaemia, neural tube defects, night-blindness, low birth weight and maternal and perinatal mortality, are common. Migration patterns from SSA to the Western world are on the rise in recent years, with Nigerians now representing the most prevalent immigrant African population in many developed countries. However, the effect of immigration, if any, on the nutritional status and pregnancy outcomes of these women in their host countries has not yet been studied. Consequently, it is unknown to what extent the nutritional deficiencies and pregnancy complications occurring in Nigeria, and other countries of SSA, present in these women post-emigration. This may result in missed opportunities for appropriate antenatal care of a potential high-risk group in pregnancy. The present review discusses the literature regarding nutrition in pregnancy among SSA women, using Nigeria as an example, the common nutrition-related complications that arise and the subsequent obstetric outcomes. The concept of dietary acculturation among immigrant groups is also discussed and deficiencies in the literature regarding studies on the diets of pregnant immigrant women are highlighted. © 2012 The Authors.

Lee, Jae Hoon; Suh, Bo Yang

2014-01-01

Carotid endarterectomy (CEA) is the standard treatment for carotid artery stenosis. New brain ischemia is a major concern associated with CEA and diffusion weighted imaging (DWI) is a good imaging modality for detecting early ischemic brain lesions. We aimed to investigate the surgical complications and identify the potential risk factors for the incidence of new brain lesions (NBL) on DWI after CEA. From January 2006 to November 2011, 94 patients who had been studied by magnetic resonance imaging including DWI within 1 week after CEA were included in this study. Data were retrospectively investigated by review of vascular registry protocol. Seven clinical variables and three procedural variables were analyzed as risk factors for NBL after CEA. The incidence of periprocedural NBL on DWI was 27.7%. There were no fatal complications, such as ipsilateral disabling stroke, myocardial infarction or mortality. A significantly higher incidence of NBL was found in ulcer positive patients as opposed to ulcer negative patients (P = 0.029). The incidence of NBL after operation was significantly higher in patients treated with conventional technique than with eversion technique (P = 0.042). Our data shows CEA has acceptable periprocedural complication rates and the existence of ulcerative plaque and conventional technique of endarterectomy are high risk factors for NBL development after CEA.

Malnutrition is a common feature of chronic liver diseases that is often associated with a poor prognosis including worsening of clinical outcome, neuropsychiatric complications as well as outcome following liver transplantation. Nutritional assessment in patients with cirrhosis is challenging owing to confounding factors related to liver failure. The objectives of nutritional intervention in cirrhotic patients are the support of liver regeneration, the prevention or correction of specific nutritional deficiencies and the prevention and/or treatment of the complications of liver disease per se and of liver transplantation. Nutritional recommendations target the optimal supply of adequate substrates related to requirements linked to energy, protein, carbohydrates, lipids, vitamins and minerals. Some issues relating to malnutrition in chronic liver disease remain to be addressed including the development of an appropriate well-validated nutritional assessment tool, the identification of mechanistic targets or therapy for sarcopenia, the development of nutritional recommendations for obese cirrhotic patients and liver-transplant recipients and the elucidation of the roles of vitamin A hepatotoxicity, as well as the impact of deficiencies in riboflavin and zinc on clinical outcomes. Early identification and treatment of malnutrition in chronic liver disease has the potential to lead to better disease outcome as well as prevention of the complications of chronic liver disease and improved transplant outcomes.

Ambulatory surgery (AS) is a contemporary subject of interest. The feasibility and safety of AS for solid abdominal organs are still dubious. In the present study, we aimed at defining potential surgical criteria for AS by analyzing a large database of patients who underwent laparoscopic liver surgery (LLS) in two French expert centers. This study was performed using prospectively filled databases including patients that underwent pure LLS between 1998 and 2015. Patients whose perioperative medical characteristics (ASA score <3, no associated extra-hepatic procedure, surgical duration ≤180 min, blood loss ≤300 mL, no intraoperative anesthesiological or surgical complication, no postoperative drainage) were potentially adapted for ambulatory LLS were included in the analysis. In order to determine the risk factors for postoperative complications, multivariate analysis was carried out. During the study period, pure LLS was performed in 994 patients. After preoperative and intraoperative characteristics screening, 174 (17.5%) patients were considered for the final analysis. Lesions (benign (46%) and liver metastases (43%)) were predominantly single with a mean size of 37 ± 32 mm in an underlying normal or steatotic liver parenchyma (94.8%). The vast majority of LLS performed were single procedures including wedge resections and liver cyst unroofing or left lateral sectionectomies (74%). The global morbidity rate was 14% and six patients presented a major complication (Dindo-Clavien ≥III). The mean length of stay was 5 ± 4 days. Multivariate analysis showed that major hepatectomy [OR 29.04 (2.26-37.19); P = 0.01] and resection of tumors localized in central segments [OR 41.24 (1.08-156.47); P = 0.04] were independent predictors of postoperative morbidity. In experienced teams, approximately 7% of highly selected patients requiring laparoscopic hepatic surgery (wedge resection, liver cyst unroofing, or left lateral sectionectomy) could benefit from ambulatory surgery management.

Neurologic complications of vaccinations.

PubMed

Miravalle, Augusto A; Schreiner, Teri

2014-01-01

This chapter reviews the most common neurologic disorders associated with common vaccines, evaluates the data linking the disorder with the vaccine, and discusses the potential mechanism of disease. A literature search was conducted in PubMed using a combination of the following terms: vaccines, vaccination, immunization, and neurologic complications. Data were also gathered from publications of the American Academy of Pediatrics Committee on Infectious Diseases, the World Health Organization, the US Centers for Disease Control and Prevention, and the Vaccine Adverse Event Reporting System. Neurologic complications of vaccination are rare. Many associations have been asserted without objective data to support a causal relationship. Rarely, patients with a neurologic complication will have a poor outcome. However, most patients recover fully from the neurologic complication. Vaccinations have altered the landscape of infectious disease. However, perception of risk associated with vaccinations has limited the success of disease eradication measures. Neurologic complications can be severe, and can provoke fear in potential vaccines. Evaluating whether there is causal link between neurologic disorders and vaccinations, not just temporal association, is critical to addressing public misperception of risk of vaccination. Among the vaccines available today, the cost-benefit analysis of vaccinations and complications strongly argues in favor of vaccination. © 2014 Elsevier B.V. All rights reserved.

National quality programs have been implemented to decrease the burden of adverse events on key outcomes in bariatric surgery. However, it is not well understood which complications have the most impact on patient health. To quantify the impact of specific bariatric surgery complications on key clinical outcomes. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. Data from patients who underwent primary bariatric procedures were retrieved from the MBSAQIP 2015 participant use file. The impact of 8 specific complications (bleeding, venous thromboembolism [VTE], leak, wound infection, pneumonia, urinary tract infection, myocardial infarction, and stroke) on 5 main 30-day outcomes (end-organ dysfunction, reoperation, intensive care unit admission, readmission, and mortality) was estimated using risk-adjusted population attributable fractions. The population attributable fraction is a calculated measure taking into account the prevalence and severity of each complication. The population attributable fractions represents the percentage reduction in a given outcome that would occur if that complication were eliminated. In total, 135,413 patients undergoing sleeve gastrectomy (67%), Roux-en-Y gastric bypass (29%), adjustable gastric banding (3%), and duodenal switch (1%) were included. The most common complications were bleeding (.7%), wound infection (.5%), urinary tract infection (.3%), VTE (.3%), and leak (.2%). Bleeding and leak were the largest contributors to 3 of 5 examined outcomes. VTE had the greatest effect on readmission and mortality. This study quantifies the impact of specific complications on key surgical outcomes after bariatric surgery. Bleeding and leak were the complications with the largest overall effect on end-organ dysfunction, reoperation, and intensive care unit admission after bariatric surgery. Furthermore, our findings suggest that an initiative targeting reduction of post-bariatric surgery VTE has the greatest potential to reduce mortality and readmission rates.

Objective To determine the effectiveness and safety of perioperative tranexamic acid use in patients undergoing total hip or knee arthroplasty in the United States. Design Retrospective cohort study; multilevel multivariable logistic regression models measured the association between tranexamic acid use in the perioperative period and outcomes. Setting 510 US hospitals from the claims based Premier Perspective database for 2006-12. Participants 872 416 patients who had total hip or knee arthroplasty. Intervention Perioperative intravenous tranexamic acid use by dose categories (none, ≤1000 mg, 2000 mg, and ≥3000 mg). Main outcome measures Allogeneic or autologous transfusion, thromboembolic complications (pulmonary embolism, deep venous thrombosis), acute renal failure, and combined complications (thromboembolic complications, acute renal failure, cerebrovascular events, myocardial infarction, in-hospital mortality). Results While comparable regarding average age and comorbidity index, patients receiving tranexamic acid (versus those who did not) showed lower rates of allogeneic or autologous transfusion (7.7% v 20.1%), thromboembolic complications (0.6% v 0.8%), acute renal failure (1.2% v 1.6%), and combined complications (1.9% v 2.6%); all P<0.01. In the multilevel models, tranexamic acid dose categories (versus no tranexamic acid use) were associated with significantly (P<0.001) decreased odds for allogeneic or autologous blood transfusions (odds ratio 0.31 to 0.38 by dose category) and no significantly increased risk for complications: thromboembolic complications (odds ratio 0.85 to 1.02), acute renal failure (0.70 to 1.11), and combined complications (0.75 to 0.98). Conclusions Tranexamic acid was effective in reducing the need for blood transfusions while not increasing the risk of complications, including thromboembolic events and renal failure. Thus our data provide incremental evidence of the potential effectiveness and safety of tranexamic acid in patients requiring orthopedic surgery. PMID:25116268

A retrospective case-controlled study. Open-door laminoplasty has been successfully used to address cervical spondylotic myelopathy and ossification of the posterior longitudinal ligament. Two common implants include rib allograft struts and metallic miniplates. The goals of this study were to compare outcomes, complications, and costs associated with these 2 implants. A retrospective review was done on 51 patients with allograft struts and 55 patients with miniplates. Primary outcomes were neck visual analog scale (VAS) pain scores and Nurick scores. Secondary outcomes included length of the procedure, estimated blood loss, rates of complications, and the direct costs associated with the surgery and inpatient hospitalization. There were no differences in demographic characteristics, diagnoses, comorbidities, and preoperative outcome scores between the 2 treatment groups. Mean follow-up was 27 months. The postoperative neck VAS scores and Nurick scores improved significantly from baseline to final follow-up for both groups, but there was no difference between the 2 groups. The average length of operation (161 vs. 136 min) and number of foraminotomies (2.7 vs. 1.3) were higher for the allograft group (P=0.007 and 0.0001, respectively). Among the miniplate group, there was no difference in complications but a trend for less neck pain for patients treated without hard collar at final follow-up (1.8 vs. 2.3, P=0.52). The mean direct costs of hospitalization for the miniplate group were 15% higher. Structural rib allograft struts and metallic miniplates result in similar improvements in pain and functional outcome scores with no difference in the rate of complications in short-term follow-up. Potential benefits of using a plate include shorter procedure length and less need for postoperative immobilization. When costs of bracing and operative time are included, the difference in cost between miniplates and allograft struts is negligible.

Canadian Potential Healthcare and Societal Cost Savings from Consumption of Pulses: A Cost-Of-Illness Analysis

Consumption of dietary pulses, including beans, peas and lentils, is recommended by health authorities across jurisdictions for their nutritional value and effectiveness in helping to prevent and manage major diet-related illnesses of significant socioeconomic burden. The aim of this study was to estimate the potential annual healthcare and societal cost savings relevant to rates of reduction in complications from type 2 diabetes (T2D) and incidence of cardiovascular disease (CVD) following a low glycemic index (GI) or high fiber diet that includes pulses, or 100 g/day pulse intake in Canada, respectively. A four-step cost-of-illness analysis was conducted to: (1) estimate the proportions of individuals who are likely to consume pulses; (2) evaluate the reductions in established risk factors for T2D and CVD; (3) assess the percent reduction in incidences or complications of the diseases of interest; and (4) calculate the potential annual savings in relevant healthcare and related costs. A low GI or high fiber diet that includes pulses and 100 g/day pulse intake were shown to potentially yield Can$6.2 (95% CI $2.6–$9.9) to Can$62.4 (95% CI $26–$98.8) and Can$31.6 (95% CI $11.1–$52) to Can$315.5 (95% CI $110.6–$520.4) million in savings on annual healthcare and related costs of T2D and CVD, respectively. Specific provincial/territorial analyses suggested annual T2D and CVD related cost savings that ranged from up to Can$0.2 million in some provinces to up to Can$135 million in others. In conclusion, with regular consumption of pulse crops, there is a potential opportunity to facilitate T2D and CVD related socioeconomic cost savings that could be applied to Canadian healthcare or re-assigned to other priority domains. Whether these potential cost savings will be offset by other healthcare costs associated with longevity and diseases of the elderly is to be investigated over the long term. PMID:28737688

Role of Internal Mammary Node Radiation as a Part of Modern Breast Cancer Radiation Therapy: A Systematic Review

DOE Office of Scientific and Technical Information (OSTI.GOV)

Verma, Vivek; Vicini, Frank; Tendulkar, Rahul D.

Purpose: Despite data from multiple randomized trials, the role of internal mammary lymph node irradiation as a part of regional nodal irradiation (IMLN RT–RNI) remains unanswered. Recent noteworthy data and modern RT techniques might identify a subset of patients who will benefit from IMLN RT–RNI, lending insight into the balance between improved outcomes and acceptable toxicity. We evaluated the current role of IMLN RT–RNI by analyzing randomized, prospective, and retrospective data. Methods and Materials: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a review of the published data was performed using PubMed to evaluate publishedmore » studies from 1994 to 2015. The information evaluated included the number of patients, follow-up period, technical aspects of RT, and outcomes (clinical outcomes, complications/toxicity). Results: We included 16 studies (4 randomized, 4 nonrandomized, 7 retrospective, and 1 meta-analysis). Although older randomized trials failed to show differences in clinical outcomes or toxicity with IMLN RT–RNI, recent randomized data suggest the potential for improved outcomes, including overall survival, with IMLN RT–RNI. Furthermore, nonrandomized data have suggested a potential benefit for central tumors with IMLN RT–RNI. Although recent data have suggested a potential increase in pulmonary complications with IMLN RT–RNI with the use of advanced radiation techniques, toxicity rates remain low with limited cardiac toxicity data available. Conclusions: Increasing data from recent randomized trials support the use of IMLN RT–RNI. IMLN RT can be considered based on the inclusion of IMLN RT as a part of RNI in recent trials and the inclusion criteria from IMLN RT–RNI trials and for patients with central or medial tumors and axillary disease.« less

Gut microbiota injury in allogeneic haematopoietic stem cell transplantation.

2018-05-01

Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is considered to be the strongest curative immunotherapy for various malignancies (primarily, but not limited to, haematologic malignancies). However, application of allo-HSCT is limited owing to its life-threatening major complications, such as graft-versus-host disease (GVHD), relapse and infections. Recent advances in large-scale DNA sequencing technology have facilitated rapid identification of the microorganisms that make up the microbiota and evaluation of their interactions with host immunity in various diseases, including cancer. This has resulted in renewed interest regarding the role of the intestinal flora in patients with haematopoietic malignancies who have received an allo-HSCT and in whether the microbiota affects clinical outcomes, including GVHD, relapse, infections and transplant-related mortality. In this Review, we discuss the potential role of intestinal microbiota in these major complications after allo-HSCT, summarize clinical trials evaluating the microbiota in patients who have received allo-HSCT and discuss how further studies of the microbiota could inform the development of strategies that improve outcomes of allo-HSCT.

Toxic effects of electrolyte and trace mineral administration in the intensive care unit.

PubMed

Besunder, J B; Smith, P G

1991-07-01

Electrolytes and trace minerals are administered routinely to ICU patients to correct deficiencies or as specific therapy for various conditions. Complications are usually related to the rate of infusion, rapidity of correction of a deficiency state, or iatrogenic poisoning with the agent. Adverse effects associated with Na+ administration included volume overload, CPM, and central nervous system bleeds. The toxic effects of K+, Ca2+, and Mg2+ are primarily related to their effects on the myocardium, nervous system, and muscle. Other than precipitating or maintaining a metabolic acidosis, Cl- administration is relatively nontoxic. Its accompanying anion (i.e., ammonium or arginine), however, may contribute significantly to patient morbidity and, possibly, mortality. Side effects observed with phosphate administration include hypocalcemia, metastatic calcification, and hypernatremia or hyperkalemia. Most of these toxicities are avoidable if appropriate precautions are taken and appropriate monitoring implemented. Finally, when administering any of these agents, the intensivist should be familiar with their toxicologic profiles and management of potential complications.

Best practices for transfusion for patients with sickle cell disease

2010-01-01

The β-globin gene mutation in sickle cell anemia results in anemia and repeated bouts of vascular occlusion. The cumulative effect of these vasocclusive events is progressive damage to many organs including the kidneys, lungs, and brain. The transfusion of red blood cells (RBC) can ameliorate many of these complications, but can be associated with both acute and chronic complications, including iron overload. The objective of the Best Practices in Transfusion Medicine for Patients with Sickle Cell Disease (SCD) Conference was to review the available published evidence and clinical experience surrounding the use of RBC transfusions for sickle cell disease by a panel of experts. The expert panel developed explicit clinical guidelines for the use of RBC in SCD patients. The panel also made recommendations for further research. A set of guidelines were produced for dissemination to pertinent stakeholders. If implemented, these clinical pathways have the potential to optimize the use of red blood cell transfusions in SCD.

Much of the fear and uncertainty around Zika epidemics stem from potential association between Zika virus (ZIKV) complications on infected pregnant women and risk of their babies being born with microcephaly and other neurological abnormalities. However, much remains unknown about its mode of transmission, diagnosis and long-term pathogenesis. Worries of these unknowns necessitate the need for effective and efficient psychosocial programs and medical-legal strategies to alleviate and mitigate ZIKV related burdens. In this light, local and global efforts in maintaining fundamental health principles of moral, medical and legal decision-making policies, and interventions to preserve and promote individual and collectiveHuman Rights, autonomy, protection of the most vulnerable, equity, dignity, integrity and beneficence that should not be confused and relegated by compassionate humanitarian assistance and support. This paper explores the potential medical and ethical-legal implications of ZIKV epidemics emergency response packages and strategies alongside optimizing reproductive and mental health policies, programs and best practice measures. Further long-term cross-borders operational research is required in elucidating Zika-related population-based epidemiology, ethical-medical and societal implications in guiding evidence-based local and global ZIKV maternal-child health complications related approaches and interventions. Core programs and interventions including future Zika safe and effective vaccines for global Zika immunization program in most vulnerable and affected countries and worldwide should be prioritized.

Hemorrhoids and anal fissures in inflammatory bowel disease.

2015-12-01

Perianal disease is a common complication of inflammatory bowel disease (IBD). It includes different conditions from more severe and potentially disabling ones, such as abscesses and fistulas, to more benign conditions such as hemorrhoids, skin tags and fissures. Most literature has been focused on anal sepsis and fistulae, as they carry the majority of disease burden and often alter the natural course of the disease. Hemorrhoids and anal fissures in patients with IBD have been overlooked, although they can represent a challenging problem. The management of hemorrhoids and fissures in IBD patients may be difficult and may significantly differ compared to the non-affected population. Historically surgery was firmly obstructed, and hemorrhoidectomy or sphincterotomy in patients with associated diagnosis of IBD was considered harmful, although literature data is scant and based on small series. Various authors reported an incidence of postoperative complications higher in IBD than in the general populations, with potential severe events. Considering that a spontaneous healing is possible, the first line management should be a medical therapy. In patients non-responding to conservative measures it is possible a judicious choice of surgical options on a highly selective basis; this can lead to acceptable results, but the risk of possible complications needs to be considered. In this review it is analyzed the current literature on the incidence, symptoms and treatment options of hemorrhoids and anal fissures in patients with Crohn's disease and ulcerative colitis.

A Critical Review of Available Retrievable Inferior Vena Cava Filters and Future Directions

Montgomery, Jennifer P.; Kaufman, John A.

2016-01-01

Inferior vena cava filters have been placed in patients for decades for protection against pulmonary embolism. The widespread use of filters has dramatically increased owing at least in part to the approval of retrievable vena cava filters. Retrievable filters have the potential to protect against pulmonary embolism and then be retrieved once no longer needed to avoid potential long-term complications. There are several retrievable vena cava filters available for use. This article discusses the different filter designs as well as the published data on these available filters. When selecting a filter for use, it is important to consider the potential short-term complications and the filters' window for retrieval. Understanding potential long-term complications is also critical, as these devices are approved for permanent placement and many filters are not retrieved. Finally, this article will address research into new designs that may be the future of vena cava filtration. PMID:27247475

When selecting a filter for use, it is important to consider the potential short-term complications and the filters' window for retrieval. Understanding potential long-term complications is also critical, as these devices are approved for permanent placement and many filters are not retrieved. Finally, this article will address research into new designs that may be the future of vena cava filtration.

Purpose: The purpose of this study was to evaluate dose-volume histogram (DVH) predictors for the development of chronic gastrointestinal (GI) complications in cervical cancer patients who underwent radical hysterectomy and postoperative concurrent nedaplatin-based chemoradiation therapy. Methods and Materials: This study analyzed 97 patients who underwent postoperative concurrent chemoradiation therapy. The organs at risk that were contoured were the small bowel loops, large bowel loop, and peritoneal cavity. DVH parameters subjected to analysis included the volumes of these organs receiving more than 15, 30, 40, and 45 Gy (V15-V45) and their mean dose. Associations between DVH parameters or clinical factors andmore » the incidence of grade 2 or higher chronic GI complications were evaluated. Results: Of the clinical factors, smoking and low body mass index (BMI) (<22) were significantly associated with grade 2 or higher chronic GI complications. Also, patients with chronic GI complications had significantly greater V15-V45 volumes and higher mean dose of the small bowel loops compared with those without GI complications. In contrast, no parameters for the large bowel loop or peritoneal cavity were significantly associated with GI complications. Results of the receiver operating characteristics (ROC) curve analysis led to the conclusion that V15-V45 of the small bowel loops has high accuracy for prediction of GI complications. Among these parameters, V40 gave the highest area under the ROC curve. Finally, multivariate analysis was performed with V40 of the small bowel loops and 2 other clinical parameters that were judged to be potential risk factors for chronic GI complications: BMI and smoking. Of these 3 parameters, V40 of the small bowel loops and smoking emerged as independent predictors of chronic GI complications. Conclusions: DVH parameters of the small bowel loops may serve as predictors of grade 2 or higher chronic GI complications after postoperative concurrent nedaplatin-based chemoradiation therapy for early-stage cervical cancer.« less

Deliberations about the functional benefits and complications of partial foot amputation: do we pay heed to the purported benefits at the expense of minimizing complications?

PubMed

Dillon, Michael P; Fatone, Stefania

2013-08-01

While discussion about the benefits and complications of partial foot amputation (PFA) is not new, much of it has hinged on anecdotal evidence and led to the popular view that the risk of complications and secondary amputation is reasonable when weighed against the perceived benefits associated with maintaining the ankle joint and residual foot length, including more normal walking, reduced energy expenditure, and improved quality of life. The research evidence makes it difficult not to question whether these benefits are valid and worth striving to achieve. When you consider that persons who undergo PFA are typically in the later years of their life and have limited mobility, it raises the question of whether we place too much emphasis on achieving the purported functional benefits of PFA and too little emphasis on achieving primary wound healing and mitigating the high rates of complications and subsequent amputation. If further research supports what we see emerging in the evidence, there will be a case to be made for selecting the level of PFA based primarily on the potential for wound healing, rather than trying to strike a balance with the perceived functional benefits. This may mean that transtibial amputation is preferable in many cases, given the lower rates of complications and secondary amputation, very similar function in terms of walking and energy expenditure, and similar lived experience of limb loss when compared with persons with PFA. Further research is needed to better understand the complications and benefits of PFA to make this a more viable, first-and-final amputation procedure.

Introduction Staple-line bleeding and leakage are the most common serious complications of laparoscopic sleeve gastrectomy. The relationship between multiple stapler firings and higher risk of postoperative complications is well defined in colorectal surgery but has not been addressed in bariatric procedures so far. Identification of new factors such as “the numbers of stapler firings used during laparoscopic sleeve gastrectomy (LSG)” as a predictor for complications can lead to optimization of the patient care at bariatric centers. Aim To determine the association between perioperative morbidity and the number of stapler firings during laparoscopic sleeve gastrectomy. Material and methods This observational study was based on retrospective analysis of prospectively collected data in patients operated on for morbid obesity in a teaching hospital/tertiary referral center for general surgery. The patients who underwent LSG were analyzed in terms of the number of stapler firings used as a new potential risk predictor for postoperative complications after surgery, adjusting for other patient- and treatment-related factors. The study included 333 patients (209 women, 124 men, mean age: 40 ±11). Results During the first 30 days after surgery, complications were observed in 18 (5.41%) patients. Multivariate analysis showed that prolonging operative time increased morbidity (every minute, OR = 1.01; 95% CI: 1.00–1.02) and the complication rate increased with the number of stapler firings (every firing, OR = 1.91; 95% CI: 1.09–3.33; p = 0.023). Conclusions Additional stapler firings above the usual number and a prolonged operation should alert a surgeon and the whole team about increased risk of postoperative complications. PMID:29643964

Prospective, single-site, randomized, Food and Drug Administration-approved investigational device exemption clinical trials of 2 cervical arthroplasty (CA) devices. To evaluate complications with CA occurring more than 4 years after the surgical procedure in Food and Drug Administration clinical trials of the Bryan and Prestige LP arthroplasty devices. Reports of several randomized clinical studies have shown CA to be a safe and effective alternative to anterior cervical fusion in the treatment of degenerative cervical disc disorders. A majority include follow-up intervals of 4 years or less. Between 2002 and 2006, 94 patients were enrolled in Food and Drug Administration studies of the Bryan and Prestige LP cervical disc devices. Charts, imaging studies, and hospital records were reviewed for those who underwent arthroplasty and returned more than 4 years after their surgical procedure with neck-related pain or dysfunction. Excluding adjacent segment disease that occurred with a similar rate for patients who underwent fusion and arthroplasty, 5 patients, all treated with arthroplasty, returned for evaluation of neck and arm symptoms between 48 and 72 months after surgery. Four patients had peridevice vertebral body bone loss. One patient had posterior device migration and presented with myelopathy. Three required revision surgery and 2 were observed. Four patients maintained follow-up and reported stabilization or improvement in symptoms. Despite their similarities, CA and fusion are not equivalent procedures in this study in regard to very late complications. Similar to large joint arthroplasty, delayed device-related complications may occur with CA. These complications commenced well beyond the time frame for complications associated with more traditional cervical spine procedures. Both patients and surgeons should be aware of the potential for very late device-related complications occurring with CA and the need for revision surgery. 1.

Use of a novel silk mesh for ventral midline hernioplasty in a mare.

Ventral midline hernia formation following abdominal surgery in horses is an uncommon complication; however, it can have serious consequences leading to increased morbidity and mortality. Currently, mesh hernioplasty is the treatment of choice for large ventral midline hernias in horses to allow potential return to normal function. Complications following mesh hernioplasty using polypropylene or polyester mesh in horses can be serious and similar to complications seen in human patients, including persistent incisional drainage, mesh infection, hernia recurrence, intra-abdominal adhesions, mesh or body wall failure, recurrent abdominal pain (colic), and peritonitis. This report describes the use of a novel bioresorbable silk mesh for repair of a large ventral midline incisional hernia in a mature, 600-kg horse. To our knowledge, this is the first report of its kind in the literature. A 9-year-old, 600-kg Warmblood mare presented with a ventral midline hernia following emergency exploratory celiotomy 20 months prior. The mare was anesthetized and a hernioplasty was performed using a novel bioresorbable silk mesh (SERI(®) Surgical Scaffold; Allergan Medical, Boston, MA). No complications were encountered either intra- or postoperatively. The mare was discharged from the hospital at 3 days postoperatively in an abdominal support bandage. At 8 and 20 weeks postoperatively, ultrasonographic assessment showed evidence of tissue ingrowth within and around the mesh. The mare was able to be bred 2 years in a row, carrying both foals to full gestation with no complications. Following both foalings, the abdomen has maintained a normal contour with no evidence of hernia recurrence. Ventral abdominal hernias can be repaired in horses using a bioresorbable silk mesh, which provides adequate biomechanical strength while allowing for fibrous tissue ingrowth. The use of a bioresorbable silk mesh for the repair of ventral hernias can be considered as a realistic option as it potentially provides significant benefits over traditional non-resorbable mesh.

Does Simultaneous Third Molar Extraction Increase Intraoperative and Perioperative Complications in Orthognathic Surgery?

PubMed

Steinbacher, Derek M; Kontaxis, Katrina L

2016-06-01

Prior to orthognathic surgery, most surgeons recommend third molar extraction. Espoused reasons include potential risk for infection, untoward osteotomies, and worsened postoperative discomfort. However, in addition to being another procedure for the patient, this may necessitate a longer preorthognathic surgery phase. The purpose of this study is to compare the outcomes of orthognathic surgery with staged versus simultaneous third molar extractions. This was a retrospective analysis of patients who underwent orthognathic surgery from 2013 to 2014, with at least a 1-year follow-up period. Patients were stratified into 2 groups: Extraction of third molars at the time of surgery and prior extraction of third molars. Primary outcomes included the occurrence of unfavorable splits, infection, bleeding, malocclusion, and hardware failure. Secondary outcomes were procedure time, postoperative pain, and length of stay. Pearson χ tests and 2-tailed unpaired t tests were performed to determine if there was an association between the simultaneous removal of third molars and the primary and secondary outcome measures, respectively. One hundred patients were included in the study. Forty-nine patients had third molars extracted at the time of surgery and fifty-one did not. Complications included unfavorable split, postoperative infection, mild postoperative bleeding, postoperative malocclusion, and hardware failure. There was no significant difference in the incidence of complications in both groups. Procedure time was not considerably increased with extractions. There was no significant difference in postoperative pain or length of stay between both groups. Removing third molars concurrently with orthognathic surgery does not increase the risk of adverse outcomes, nor does it significantly influence hospital course.

Incisional hernia is a frequent complication after midline laparotomy. Surgical hernia repair is associated with complications, but no clear predictive risk factors have been identified. The European Hernia Society (EHS) classification offers a structured framework to describe hernias and to analyze postoperative complications. Because of its structured nature, it might prove to be useful for preoperative patient or treatment classification. The objective of this study was to investigate the EHS classification as a predictor for postoperative complications after incisional hernia surgery. An analysis was performed using a registry-based, large-scale, prospective cohort study, including all patients undergoing incisional hernia surgery between September 1, 2011 and February 29, 2016. Univariate analyses and multivariable logistic regression analysis were performed to identify risk factors for postoperative complications. A total of 2,191 patients were included, of whom 323 (15%) had 1 or more complications. Factors associated with complications in univariate analyses (p < 0.20) and clinically relevant factors were included in the multivariable analysis. In the multivariable analysis, EHS width class, incarceration, open surgery, duration of surgery, Altemeier wound class, and therapeutic antibiotic treatment were independent risk factors for postoperative complications. Third recurrence and emergency surgery were associated with fewer complications. Incisional hernia repair is associated with a 15% complication rate. The EHS width classification is associated with postoperative complications. To identify patients at risk for complications, the EHS classification is useful. Copyright © 2017.

Tube thoracostomy (TT) placement belongs among the most commonly performed procedures. Despite many benefits of TT drainage, potential for significant morbidity and mortality exists. Abdominal or thoracic injury, fistula formation and vascular trauma are among the most serious, but more common complications such as recurrent pneumothorax, insertion site infection and nonfunctioning or malpositioned TT also represent a significant source of morbidity and treatment cost. Awareness of potential complications and familiarity with associated preventive, diagnostic and treatment strategies are fundamental to satisfactory patient outcomes. This review focuses on chest tube complications and related topics, with emphasis on prevention and problem-oriented approaches to diagnosis and treatment. The authors hope that this manuscript will serve as a valuable foundation for those who wish to become adept at the management of chest tubes. PMID:25024942

Paget’s disease (PD) is a chronic metabolically active bone disease, characterized by a disturbance in bone modelling and remodelling due to an increase in osteoblastic and osteoclastic activity. The vertebra is the second most commonly affected site. This article reviews the various spinal pathomechanisms and osseous dynamics involved in producing the varied imaging appearances and their clinical relevance. Advanced imaging of osseous, articular and bone marrow manifestations of PD in all the vertebral components are presented. Pagetic changes often result in clinical symptoms including back pain, spinal stenosis and neural dysfunction. Various pathological complications due to PD involvement result in these clinical symptoms. Recognition of the imaging manifestations of spinal PD and the potential complications that cause the clinical symptoms enables accurate assessment of patients prior to appropriate management.

Sulfur mustard (SM) is an alkylating chemical warfare agent with high military significance due to its high toxicity, resistance and availability. SM was widely used in military conflicts, the last being the Iran-Iraq war with more than 100,000 Iranians exposed, one-third of whom are still suffering from late effects. The intensity of the delayed complications correlates to the extent, the area and the route of exposure. The clinical manifestations most commonly involve respiratory, ocular and dermal effects. Respiratory complications include dyspnea, cough and expectorations and various obstructive and restrictive lung diseases. Dermal complications are itching, burning sensation, blisters, dry skin, dermatitis and pigmentary changes. Ocular complications include photophobia, red eye, tearing, corneal ulcers and blindness. Although the picture remains incomplete the major mechanisms responsible for the clinical and pathological effects of SM are: DNA alkylation and cross-linking, protein modification and membrane damage in addition to induction of inflammatory mediators in the target tissues causing extensive necrosis, apoptosis and loss of tissue structure. The current report reviews long-term complications of SM exposure, focusing on new treatments tested in clinical trials conducted on humans. Such treatments include: N-acetyl cysteine, bronchodilators, corticosteroids, Interferon-gamma, furosemide and morphine for the respiratory complications. Ocular complications may entail: Invasive procedures treating corneal complication, limbal ischemia and stem cell deficiency. Treatment for dermatological complications include: anti-depressants, pimercrolimus, Unna's boot, capsaicin, phenol and menthol, Aloe vera and olive oil, curcumin and Interferon-gamma.

Pseudoaneurysm as a complication of ankle arthroscopy.

We describe a case of pseudoaneurysm of the anterior tibial artery as a complication after arthroscopic ankle synovectomy, in which standard anterolateral and anteromedial portals were used. Pseudoaneurysm has been previously reported as a complication in ankle arthroscopy with the use of the anterocentral portal. Previously described anatomic variations of the tibial artery and its close relationship with the anterior ankle capsule may complicate arthroscopic surgery, especially when aggressive synovectomy is performed. Anterior tibial artery aneurysm is a rare complication of ankle arthroscopy, but its potential catastrophic sequelae must not be underestimated.

Tumor lysis syndrome (TLS) is a serious complication of malignancies and can result in renal failure or death. In tumors with a high proliferative rate with a relatively large mass and a high sensitivity to cytotoxic agents, the initiation of therapy often results in the rapid release of intracellular anions, cations and the metabolic products of proteins and nucleic acids into the bloodstream. The increased concentrations of uric acid, phosphates, potassium and urea can overwhelm the body's homeostatic mechanisms to process and excrete these materials and result in the clinical spectrum associated with TLS. Typical clinical sequelae include gastrointestinal disturbances, neuromuscular effects, cardiovascular complications, acute renal failure and death. Tumor lysis syndrome can also compromise the efficacy or administration of curative therapies. Available evidence suggests that the incidence of clinical TLS is approximately 3-7% for acute leukemias and 4-11% for lymphomas. Pediatric cancers are the leading cause of death by disease in children. The most common pediatric cancers include the leukemias, lymphomas, central nervous system tumors and neuroblastoma. Thus, TLS is a major concern to practitioners caring for pediatric oncology patients. Given the complexity of TLS prevention and treatment, a multidisciplinary approach involving the collaboration of medical oncologists/ hematologists and nephrologists has the greatest potential of ensuring optimal patient outcomes. Rehydration is fundamental in the management of TLS in addition to the current standard therapy for hyperuricemia which include rasburicase and allopurinol. The early recognition and treatment of metabolic abnormalities often prevents the severe and life-threatening complications associated with tumor lysis syndrome.

What are the fertility outcomes in women wishing to conceive after experiencing a severe complication from surgical removal of colorectal endometriosis? The pregnancy rate (PR) among women who wished to conceive after a severe complication of surgery for colorectal endometriosis was 41.2% (spontaneously for 80%, after ART procedure for 20%). While the long-term benefit of surgery on pain and quality of life is well documented for women with colorectal endometriosis, it exposes women to the risk of severe complications. However, little is known about fertility outcomes in women experiencing such severe postoperative complications. This retrospective cohort study included women who experienced a severe complication after surgery for colorectal endometriosis between January 2004 and June 2014, and who wished to conceive. A total of 53 patients met the inclusion criteria. The fertility outcome was available for 48 women, who were therefore included in the analysis. The median follow-up was 5 years. All the women underwent complete removal of colorectal endometriosis. Postoperative severe complications were defined as grades III-IV of the Clavien-Dindo classification. Fertility outcomes, PR and cumulative pregnancy rate (CPR), were estimated. Most women experienced a grade IIIb complication (83.3%). Of 48 women, 20 became pregnant (overall PR: 41.2%); spontaneously for 16 (80%) and after ART procedure for 4 (20%). The median interval between surgery and first pregnancy was 3 years. The live birth rate was 14/48 (29.2%). The 5-year CPR was 46%. A lower CPR was found for women who experienced anastomotic leakage (with or without rectovaginal fistula) (P = 0.02) or deep pelvic abscess (with or without anastomotic leakage) (P = 0.04). Due to a lack of information, no sub-analysis was done to investigate other parameters potentially impacting fertility outcomes. The PR for our population was slightly lower to that observed in the literature for women who experience such surgery without consideration for the occurrence of complications. However, 'severe complications' covers a range of conditions which are likely to have a very different impacts on fertility. Even if the PR and CPR appear satisfactory, septic complications can negatively impact fertility outcomes. Rapid ART may be a good option for these patients. No funding was required for the current study. Pr H. Roman reported personal fees from Plasma Surgical Inc.

2015-06-01

Parastomal hernia (PSH) is the most frequent long-term stoma complication with serious negative effects on quality of life. Surgical revision is often required and has a substantial morbidity and recurrence rate. The development of PSH requires revisional surgery with a substantial perioperative morbidity and high failure rate in the long-term follow-up. Prophylactic parastomal mesh insertion during stoma creation has the potential to reduce the rate of PSH, but carries the risk of early and late mesh-related complications such as infection, fibrosis, mesh shrinkage, and/or bowel erosion. We developed a new stomaplasty ring (KORING), which is easy to implant, avoids potential mesh-related complications, and has a high potential of long-term prevention of PSH. Here we describe the technique and the first use. © The Author(s) 2014.

Impact of preoperative hormonal stimulation on postoperative complication rates after hypospadias repair: a meta-analysis.

2017-06-01

To improve the surgical outcome of hypospadias repair surgery, preoperative hormonal stimulation (PHS) has been proposed. We conducted a meta-analysis to evaluate the impact of preoperative hormonal stimulation (PHS) treatment on complication rates following hypospadias repair surgery. A comprehensive literature search up to June 1st, 2015 was carried out for relevant studies. After literature identification and data extraction, relative ratio (RR) was calculated to compare postoperative complication rates. Heterogeneity among individual studies was tested using the Cochran χ2 Q test and quantified by calculating the I2 index. Meta-regression was applied to find potential affective factors. Overall, 428 patients from 6 studies had undergone primary hypospadias repair, of which 171 (39.95%) received some form of PHS with human chorionic gonadotropin (HCG), dihydrotestosterone (DHT) or testosterone (T). They underwent three different types of surgical techniques, including onlay island flap (N.=277), tubularized incised plate (N.=99) and Koyanagi urethroplasty (N.=52). These 6 studies classified the complication rates based on PHS. The relative ratio (RR) for a complication occurring following PHS use was 1.18 (95% CI: 0.70-2.00, Z=0.91, P=0.539). Significant heterogeneity (I2=47.1%, P=0.092) among various research literature was found and meta-regression was undertaken for the heterogeneity, but surgical technique, mean age of patients at time of surgery, types of PHS and the quality of studies were not the cause of heterogeneity. Use of T, DHT and HCG prior to hypospadias repair does not appear to increase the incidence of postoperative complications, but further investigation is needed.

Recipient-site infection after oropharyngeal reconstruction is a potentially disastrous complication. Although studies suggest that perioperative antibiotics reduces infection rates in these patients from 87% to 20%, there is no consensus regarding what constitutes the most appropriate antibiotic regimen and duration of treatment. A retrospective review of perioperative antibiotic administration was performed of all patients who underwent local, pedicled, or free flap oropharyngeal reconstruction after oncologic resection by a single surgeon at a single institution between 2007 and 2013 to assess for recipient-site complications. Ninety-seven patients underwent 100 reconstructions (61 free flap reconstructions, 39 pedicled/local flap reconstructions) and all received a combination of intravenous (IV) antibiotic agents designed to cover oral flora. There were 23 (23%) recipient-site complications, which included cellulitis (9%), mucocutaneous fistula (5%), abscess (5%), and wound dehiscence (4%). Duration of antibiotic prophylaxis, defined as less than 48 hours (short-course) or greater than 48 hours (long-course), was not a significant predictor of recipient-site complication. Significant risk factors for recipient-site complications were clindamycin prophylaxis (P < 0.008), increased duration of surgery (P < 0.047), and advanced age (P < 0.034). Recipient-site complication was found to be a significant predictor of both increased length of hospital stay (P < 0.001) and increased time to the resumption of enteral feeds (P < 0.035). These data suggest that extended courses of perioperative antibiotics do not confer additional benefits in patients undergoing oropharyngeal reconstruction. We recommend a limited 48-hour course of prophylactic antibiotics with sufficient aerobic and anaerobic coverage to help minimize the incidence of antibiotic-related morbidities.

Safely Combining Abdominoplasty with Aggressive Abdominal Liposuction Based on Perforator Vessels: Technique and a Review of 300 Consecutive Cases

PubMed Central

Smith, Lane F.

2015-01-01

Background: There continues to be controversy about performing abdominoplasty concurrently with abdominal liposuction. The concern is that liposuction on the already vascularly compromised abdominal flap will lead to increased complications and flap necrosis. The central abdomen is supplied by the epigastric system. If perforator vessels from this system are spared, the blood supply to the abdomen can be spared and liposuction should be able to be safely performed on the elevated abdominal flap. The purpose of this study was to evaluate the safety of abdominoplasty with concurrent abdominal liposuction when a perforator vessel is spared. Methods: A standard abdominoplasty was performed, sparing one or two perforator vessels from the deep superior epigastric artery system. A retrospective chart review of 300 consecutive patients who underwent abdominoplasty surgery combined with concurrent abdominal liposuction was performed. Complications, total volume of abdominal liposuction, and results were reviewed. Results: The overall complication rate was 17.3 percent (52 patients). Sixteen percent (48 patients) suffered minor complications and 1.3 percent (four patients) suffered major complications. Conclusions: Abdominoplasty can be combined safely with concurrent abdominal liposuction when a perforator vessel is spared. The combination of concurrent liposuction with abdominoplasty showed no increase in complication rates when a perforator vessel was spared. The perforator vessels are located consistently in a 2-cm radius located 4 cm from the midline and 6 cm from the subcostal margin. The potential advantages of abdominoplasty with concurrent liposuction include a better postoperative cosmetic result. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV. PMID:25919250

Strategies for prevention of iatrogenic inferior vena cava filter entrapment and dislodgement during central venous catheter placement.

Iatrogenic migration of inferior vena cava (IVC) filters is a potentially life-threatening complication that can arise during blind insertion of central venous catheters when the guide wire becomes entangled with the filter. In this study, we reviewed the occurrence of iatrogenic migration of IVC filters in the literature and assessed methods for preventing this complication. A literature search was conducted to identify reports of filter/wire entrapment and subsequent IVC filter migration. Clinical outcomes and complications were identified. A total of 38 cases of filter/wire entrapment were identified. All of these cases involved J-tip guide wires. Filters included 23 Greenfield filters, 14 VenaTech filters, and one TrapEase filter. In 18 cases of filter/wire entrapment, there was migration of the filter to the heart and other central venous structures. Retrieval of the migrated filter was successful in only four of the 18 cases, and all of these cases were complicated by strut fracture and distant embolization of fragments. One patient required resuscitation during retrieval. Successful disengagement was possible in 20 cases without filter migration. Iatrogenic migration of an IVC filter is an uncommon complication related to wire/filter entrapment. This complication can be prevented with knowledge of the patient's history, use of proper techniques when placing a central venous catheter, identification of wire entrapment at an early stage, and use of an appropriate technique to disengage an entrapped wire.

Measures of body weight and anthropometrics such as body mass index (BMI) are commonly used to assess nutritional status in clinical conditions including cancer. Extensive research has evaluated associations between body weight and prognosis in ovarian cancer patients, yet little is known about the potential impact of body composition (fat mass (FM) and fat-free mass (FFM)) in these patients. Thus, the purpose of this publication was to review the literature (using PubMed and EMBASE) evaluating the impact of body weight and particularly body composition on surgical complications, morbidity, chemotherapy dosing and toxicity (as predictors of prognosis), and survival in ovarian cancer patients. Body weight is rarely associated with intra-operative complications, but obesity predicts higher rates of venous thromboembolism and wound complications post-operatively in ovarian cancer patients. Low levels of FM and FFM are superior predictors of length of hospital stay compared to measures of body weight alone, but the role of body composition on other surgical morbidities is unknown. Obesity complicates chemotherapy dosing due to altered pharmacokinetics, imprecise dosing strategies, and wide variability in FM and FFM. Measurement of body composition has the potential to reduce toxicity if the results are incorporated into chemotherapy dosing calculations. Some findings suggest that excess body weight adversely affects survival, while others find no such association. Limited studies indicate that FM is a better predictor of survival than body weight in ovarian cancer patients, but the direction of this relationship has not been determined. In conclusion, body composition as an indicator of nutritional status is a better prognostic tool than body weight or BMI alone in ovarian cancer patients.

Imported falciparum malaria is characterized by a broad spectrum of potentially life-threatening complications that may arise even after initiation of appropriate antimalarial drug therapy. Hence, at Heidelberg University Hospital, all patients with newly diagnosed falciparum malaria are initially treated in the intermediate care unit (IMC) or intensive care unit (ICU). The present study was undertaken to evaluate critically the benefit of this strategy, which includes daily consultation with senior specialists in tropical medicine. We conducted a retrospective cohort study at the 14-bed combined IMC/ICU of a 1,685-bed university hospital. A cohort of 122 patients with imported falciparum malaria admitted from 1 January 1996 to 31 December 2003 was included. Thirty-four patients (27.9%) developed complications, defined according to the current World Health Organization classification. Most patients (80.3%) studied did not take the recommended chemoprophylaxis against malaria. The majority of patients (89.3% [n = 109]) could be adequately treated in the IMC. Life-threatening complications requiring ICU support occurred in 13 patients (10.7%). All complications were successfully managed. Fifty-five patients (45.1%) fulfilling recently published criteria for outpatient treatment had an excellent therapeutic response and did not require ICU support. This retrospective evaluation demonstrated favourable therapeutic results in hospitalized patients with imported falciparum malaria. Both initial treatment in the medical IMC/ICU and close collaboration between intensivists and specialists in tropical medicine may improve disease outcome among affected patients. Prospective studies are needed to confirm these preliminary findings.

To investigate the technical and clinical safety and efficacy of using a newly designed T-configured stent graft for palliative treatment of advanced hilar malignant biliary obstructions. This is a prospective study that enrolled 30 patients who had malignant hilar obstructions from May 2007 to November 2008. All patients were treated with percutaneous transhepatic placement of two specially designed stent grafts in a T configuration. Technical success, evaluation of blocked branching ducts, complications, clinical success, stent patency time, and patient survival rates were analyzed. Stent graft deployment was technically successful in all patients. The bilirubin level and the bile duct diameter decreases were statistically significant after stent placement (P < .001), and all patients showed clinical improvement. Minor complications, including procedure-related complications (self-limiting hemobilia [n = 3], perihepatic biloma [n = 1], and acute pancreatitis [n = 1]) and rapidly resolving cholangitis (n = 5), occurred in ten patients (33.3%). Major complications, including acute cholecystitis, occurred in three patients (10%). Stent occlusion occurred in 12 patients (40%) after a mean period of 160 days (range, 82-307 days). The median survival and stent patency times were 334 days (range, 195.6-472.4 days) and 279 days (range, 194.7-363.3 days), respectively. There were no statistical differences in age, sex, Bismuth type, or number of blocked branching ducts. The initial results of percutaneous palliative treatment of advanced hilar malignancies with T-configured stent grafts suggest that they are safe and potentially clinically effective.

A review of clinical publications, current knowledge, and recent developments regarding the etiology of ischiovertebral dysplasia was combined with a clinical review of the condition. To acquaint orthopedic spine surgeons with identification patterns of ischiovertebral dysplasia in order to provide them with guidelines about spine management and which complications to expect. Ischiovertebral dysplasia is a rare skeletal dysplasia that may appear in a sporadic fashion or be inherited with an autosomal dominant inheritance pattern. It is defined by the association of an ischiopubic ramus hypoplasia and a vertebral dysplasia. It leads to a specific spine deformity whose management and complications should be clarified. Thirty consecutive patients from 0 to 31 years of age with ischiovertebral dysplasia were included from 5 centers specialized in congenital spinal deformities. Frontal and sagittal Cobb angles before treatment, natural history of the curves, therapeutic options, and their complications were systematically analyzed. All the patients had a vertebral dysplasia and 28 of them developed a spinal deformity. This deformity was an extremely severe thoracic kyphoscoliosis in 25 cases. The other deformities were a thoracolumbar scoliosis in 1 case and a thoracolumbar kyphosis in 2 cases. The management of the thoracic kyphoscoliosis was always challenging and complications included death by respiratory failure (3 cases) and neurological impairment (9 cases). Recognizing the occurrence of ischioverterbral dysplasia is very important to allow for dedicated treatment. The authors advocate preoperative distraction and circumferential fusion to prevent progression of the curve and to avoid the potentially fatal sequelae associated with this disorder. 4.

Effects of psychoeducation on helpful support for complicated grief: a preliminary randomized controlled single-blind study.

Nam, I S

2016-01-01

Complicated grief is a distinct psychological response of individuals facing the loss of a loved one and can lead to many types of adverse health outcomes. Although social support may be beneficial, few studies have examined the beneficial effects of helpful support on complicated grief following bereavement. A randomized controlled trial was conducted. Bereaved participants and supporters were randomized to psychoeducation on complicated grief and helpful social support or psychoeducation on complicated grief. The primary outcome was the Inventory of Complicated Grief. The results showed that psychoeducation of supporters of bereaved individuals has significant beneficial effects. Particularly, symptoms of complicated grief were decreased in bereaved individuals with supporters that received psychoeducation. The results highlight the potential of psychoeducation to facilitate helpful social support and reduce complicated grief.

Facial resurfacing with a CO 2 laser has been used for treatment of pathologic lesions and for cosmetic purposes. Postoperative complications and problems after laser resurfacing include infections, acneiform lesions, and pigment changes. This retrospective study describes the most common problems and complications in 105 patients and assesses postoperative pain in 38 patients. All patients received CO 2 laser resurfacing for treatment of malignant/premalignant lesions and had postoperative follow-up to assess problems and complications. Some had follow-up to assess postoperative pain. All patients had Fitzpatrick I-III skin types and underwent the same perioperative care regimen. There were 11 problems and 2 complications. Problems included infection, acneiform lesion/milia, and uncontrolled postoperative pain. Complications included hyperpigmentation. Among the postoperative pain group, 53% reported no pain and the rest had mild or moderate pain. Complications are rare. Infection and acneiform lesions/milia were the most common problems, as previously reported. Most patients do not experience postoperative pain. Copyright © 2016 Elsevier Inc. All rights reserved.

2017-09-01

The purpose of this study is to analyze the current evidence regarding the use of statins in patients with chronic liver disease and cirrhosis. Chronic liver disease (CLD), cirrhosis, and its complications, including hepatocellular carcinoma (HCC), are significant public health problems. The use of statins in patients with CLD has been a matter of concern, and physicians are often reluctant to its prescription in these patients. This mainly relates to the potential occurrence of drug-induced liver injury. However, newer evidence from pre-clinical and clinical research has shown that statins are drugs with a potentially beneficial impact on the natural history of cirrhosis, on portal hypertension, and in HCC prevention. In this review, we summarize current evidence regarding the influence of statins in endothelial dysfunction in CLD, their ability to modulate hepatic fibrogenesis, and their vasoprotective effects in portal hypertension; we also focus on existing data about the impact of statins in cirrhosis development, progression, and complications and critically assess the current concerns about its use in patients with CLD.

Intra-arterial Methylprednisolone Infusion in Treatment-Resistant Graft-Versus-Host Disease

Weintraub, Joshua L., E-mail: Joshua.Weintraub@mssm.edu; Belanger, Adam R.; Sung, Chris C.

Acute graft-versus-host disease (GVHD) is a potentially fatal complication following allogeneic hematopoietic stem cell transplant. Standard primary therapy for acute GVHD includes systemic steroids, often in combination with other agents. Unfortunately, primary treatment failure is common and carries a high mortality. There is no generally accepted secondary therapy for acute GVHD. Although few data on localized therapy for GVHD have been published, intra-arterial injection of high-dose corticosteroids may be a viable option. We treated 11 patients with steroid-resistant GVHD using a single administration of intra-arterial high-dose methylprednisolone. Three patients (27%) died periprocedurally. Four patients (36%) had a partial response tomore » intra-arterial treatment and were discharged on total parenteral nutrition and oral medication. Four patients (36%) had a complete response and were discharged on oral diet and oral medication. No immediate treatment or procedure-related complications were noted. Twenty-seven percent of patients survived long-term. Our preliminary results suggest that regional intra-arterial treatment of steroid-resistant GVHD is a safe and potentially viable secondary therapy in primary treatment-resistant GVHD.« less

This study presents the results of comparative investigations aimed to determine microbiota that can occur in the oral environment in different human populations. The objective of the research was to identify pathogenic oral microbiota, the potential cause of health complications in patients of different population groups. The study included 95 patients requiring dental or surgical treatment; their oral cavity environment microbiota as risk factors of local and general infections were assessed. In clinical assessment, differences occurred in oral cavity conditions between patients with malformations of the masticatory system, kidney allograft recipients and individuals without indications for surgical procedures. The presence of various pathogenic and opportunistic bacterial strains in oral cavities were revealed by direct microscopic and in vitro culture techniques. Colonization of oral cavities of patients requiring surgical treatment by the potentially pathogenic bacteria constitutes the threat of their spread, and development of general infections. Assessment of oral cavity infectious microbiota should be performed as a preventive measure against peri-surgical complications.

Crisis management in the treatment of childhood acute lymphoblastic leukemia: putting right what can go wrong (emergency complications of disease and treatment).

PubMed

Hough, Rachael; Vora, Ajay

2017-12-08

The improvement in overall survival in children with acute lymphoblastic leukemia (ALL) over the last 5 decades has been considerable, with around 90% now surviving long term. The risk of relapse has been reduced to such an extent that the risk of treatment-related mortality is now approaching that of mortality caused by relapse. Toxicities may also lead to the suboptimal delivery of chemotherapy (treatment delays, dose reductions, dose omissions), potentially increasing relapse risk, and short- and long-term morbidity, adding to the "burden of therapy" in an increasing number of survivors. Thus, the need to reduce toxicity in pediatric ALL is becoming increasingly important. This work focuses on the risk factors, pathogenesis, clinical features, and emergency management of the life-threatening complications of ALL at presentation and during subsequent chemotherapy, including leucostasis, tumor lysis syndrome, infection, methotrexate encephalopathy, thrombosis, and pancreatitis. Potential strategies to abrogate these toxicities in the future are also discussed. © 2016 by The American Society of Hematology. All rights reserved.

Diskitis, Osteomyelitis, Spinal Epidural Abscess, Meningitis, and Endocarditis Following Sacroiliac Joint Injection for the Treatment of Low-Back Pain in a Patient on Therapy for Hepatitis C Virus.

PubMed

Nagpal, Geeta; Flaherty, John P; Benzon, Honorio T

Sacroiliac joint injections are frequently performed procedures in the management of acute and chronic low-back pain, including patients with various immunocompromised states. Infectious complications following these procedures along with other spinal injections are rarely reported, but the true incidence is unknown. The purpose of this report is to highlight the devastating neurologic sequela that can occur, and to discuss potential future management strategies. We present a patient who developed diskitis, osteomyelitis, spinal epidural abscess, meningitis, and endocarditis from Staphylococcus aureus, all of which developed shortly after a sacroiliac joint injection. The patient was on treatment for hepatitis C virus, and the resulting immunocompromised state likely contributed to the outcome. Immunocompromised patients should be identified prior to treatment, and the small possibility of devastating complications should be thoughtfully weighed against the potential benefit of the procedure. Conservative management should be maximized initially, and if a procedure is done, strict asepsis must be maintained. Prophylaxis for S. aureus should be considered for immunocompromised patients undergoing interventional spine procedures.

Accumulation of advanced glycation endproducts (AGE) from nonenzymatic glycation of proteins has been implicated in several diabetic complications including diabetic cataract. Previously, we have reported that extracts of dietary agents such as cinnamon have the potential to inhibit AGE formation. In this study, we have shown procyanidin-B2 as the active component of cinnamon that is involved in AGE inhibition using bioassay-guided fractionation of eye lens proteins under in vitro conditions. The data indicate that procyanidin-B2 enriched fraction scavenges dicarbonyls. Further, procyanidin-B2 fraction of cinnamon inhibited the formation of glycosylated hemoglobin in human blood under ex vivo conditions. We have also demonstrated the physiological significance of procyanidin-B2 fraction in terms of delay of diabetic cataract through inhibition of AGE in diabetic rats. These findings establish the antiglycating potential of procyanidin-B2 fraction of cinnamon which suggests a scope for controlling AGE-mediated diabetic complications by food sources that are rich in proanthocyanidins like procyanidin-B2. © 2013 International Union of Biochemistry and Molecular Biology.

Management to optimize organ procurement in brain dead donors.

PubMed

Mascia, L; Mastromauro, I; Viberti, S; Vincenzi, M; Zanello, M

2009-03-01

The demand for donor organs continues to exceed the number of organs available for transplantation. Many reasons may account for this discrepancy, such as the lack of consent, the absence of an experienced coordinator team able to solve logistical problems, the use of strict donor criteria, and suboptimal, unstandardized critical care management of potential organ donors. This has resulted in efforts to improve the medical care delivered to potential organ donors, so as to reduce organ shortages, improve organ procurement, and promote graft survival. The physiological changes that follow brain death entail a high incidence of complications jeopardizing potentially transplantable organs. Adverse events include cardiovascular changes, endocrine and metabolic disturbances, and disruption of internal homeostasis. Brain death also upregulates the release of pro-inflammatory molecules. Recent findings support the hypothesis that a preclinical lung injury characterized by an enhanced inflammatory response is present in potential donors and may predispose recipients to an adverse clinical prognosis following lung transplantation. In clinical practice, hypotension, diabetes insipidus, relative hypothermia, and natremia are more common than disseminated intravascular coagulation, cardiac arrhythmias, pulmonary oedema, acute lung injury, and metabolic acidosis. Strategies for the management of organ donors exist and consist of the normalization of donor physiology. Management has been complicated by the recent use of ''marginal'' donors and donors of advanced age or with ''extended'' criteria. Current guidelines suggest that the priority of critical care management for potential organ donors should be shifted from a ''cerebral protective'' strategy to a multimodal strategy aimed to preserve peripheral organ function.

A cost-effectiveness analysis to illustrate the impact of cost definitions on results, interpretations and comparability of pharmacoeconomic studies in the US.

PubMed

Tunis, Sandra L

2009-01-01

There is a lack of a uniform proxy for defining direct medical costs in the US. This potentially important source of variation in modelling and other types of economic studies is often overlooked. The extent to which increased expenditures for an intervention can be offset by reductions in subsequent service costs can be directly related to the choice of cost definitions. To demonstrate how different cost definitions for direct medical costs can impact results and interpretations of a cost-effectiveness analysis. The IMS-CORE Diabetes Model was used to project the lifetime (35-year) cost effectiveness in the US of one pharmacological intervention 'medication A' compared with a second 'medication B' (both unspecified) for type 2 diabetes mellitus. The complications modelled included cardiovascular disease, renal disease, eye disease and neuropathy. The model had a Markov structure with Monte Carlo simulations. Utility values were derived from the published literature. Complication costs were obtained from a retrospective database study that extracted anonymous patient-level data from (primarily private payer) adjudicated medical and pharmaceutical claims. Costs for pharmacy services, outpatient services and inpatient hospitalizations were included. Cost definitions for complications included charged, allowed and paid amounts, and for medications included both wholesale acquisition cost (WAC) and average wholesale price (AWP). Costs were reported in year 2007 values. The cost-effectiveness results differed according to the particular combination of cost definitions employed. The use of charges greatly increased costs for complications. When the analysis incorporated WAC medication prices with charged amounts for complication costs, the incremental cost-effectiveness ratio (ICER) for medication A versus medication B was $US6337 per QALY. When AWP prices were used with charged amounts, medication A became a dominant treatment strategy, i.e. lower costs with greater effectiveness than medication B. For both allowed and paid scenarios, there was a difference in the ICER of over $US10,300 per QALY when medication prices were defined by WAC versus AWP. Ratios of medication costs to cardiovascular complication costs ranged from under 0.45 to over 1.7, depending upon the combination of costing definitions. Explicitly addressing the cost-definition issue can help provide meaningful cost-effectiveness data to payers for policy development and management of healthcare expenditures. It can also help move the pharmacoeconomics and outcomes research fields forward in terms of both methodology and practical application.

Urological complications of coitus.

Eke, N

2002-02-01

To ascertain the urological complications of coitus, as the proximity of the lower urinary tract to the organs of coitus exposes the tract to coital trauma. Medline was searched from 1966 to 2000 to identify reports on coital injuries. Publications and relevant references were retrieved. Those reporting urological complications were selected for analysis. In all, 1454 cases of reported coital injuries were reviewed; 790 occurred in men while 664 occurred in women, mainly in the genital area. Physical urological complications were more common in men than in women. The injuries were often sustained during voluntary coitus, but one penile fracture was sustained during an attempted rape. The presentations included penile swellings and deviations, haemorrhage, erectile dysfunction and urinary incontinence. Complications included vesicovaginal fistulae, bladder and cavernosal ruptures, and urinary tract infections. Rare complications included isolated rupture of the penile vasculature. Major risk factors included penovaginal disproportion, excessive force at coitus, urethral coitus, fellatio and anal intercourse. Urethral injuries were the commonest complications; in men these were associated with 10-38% of penile fractures. The treatments included cold compress and anti-inflammatory agents in contusions, repairs of lacerations, closure of fistulae and urethral and vaginal reconstruction. The results of treatment were essentially good. Recurrent penile fractures were reported. Coitus, although pleasurable, may be risky. The complications have been termed 'faux pas' implying that they are preventable. While the ultimate prevention is abstinence, this is an unrealistic prescription. Therefore, efforts are necessary to identify risk factors to enable preventive strategies.

Nursing administration of medication via enteral tubes in adults: a systematic review.

PubMed

Phillips, Nicole M; Nay, Rhonda

Enteral tubes are frequently inserted as part of medical treatment in a wide range of patient situations. Patients with an enteral tube are cared for by nurses in a variety of settings, including general and specialised acute care areas, aged care facilities and at home. Regardless of the setting, nurses have the primary responsibility for administering medication through enteral tubes. Medication administration via an enteral tube is a reasonably common nursing intervention that entails a number of skills, including preparing the medication, verifying the tube position, flushing the tube and assessing for potential complications. If medications are not given effectively through an enteral tube, harmful consequences may result leading to increased morbidity, for example, tube occlusion, diarrhoea and aspiration pneumonia. There are resultant costs for the health-care system related to possible increased length of stay and increased use of equipment. Presently what is considered to be best practice to give medications through enteral tubes is unknown. The objective of this systematic review was to determine the best available evidence on which nursing interventions are effective in minimising the complications associated with the administration of medications via enteral tubes in adults. Nursing interventions and considerations related to medication administration included form of medication, verifying tube placement before administration, methods used to give medication, methods used to flush tubes, maintenance of tube patency and specific practices to prevent possible complications related to the administration of enteral medications. The following databases were searched for literature reported in English only: CINAHL, MEDLINE, The Cochrane Library, Current Contents/All Editions, EMBASE, Australasian Medical Index and PsychINFO. There was no date restriction applied. In addition, the reference lists of all included studies were scrutinised for other potentially relevant studies. Systematic reviews of randomised controlled trials (RCTs) and RCTs that compared the effectiveness of nursing interventions and considerations used in the administration of medications via enteral tubes. Other research methods, such as non-randomised controlled trials, longitudinal studies, cohort and case control studies, were also included. Exclusion criteria included studies investigating drug-nutrient interactions or the bioavailability of specific medications. Initial consideration of potential relevance to the review was carried out by the primary author (NP). Two reviewers independently assessed study eligibility for inclusion. A meta-analysis could not be undertaken, as there were no comparable RCTs identified. All data were presented in a narrative summary. There is very limited evidence regarding the effectiveness of nursing interventions in minimising the complications associated with enteral tube medication administration in adults. The review highlights a lack of high quality research on many important nursing issues relating to enteral medication administration. There is huge scope for further research. Some of the evidence that was identified included that nurses should consider the use of liquid form medications as there may be fewer tube occlusions than with solid forms in nasoenteral tubes and silicone percutaneous endoscopic gastronomy tubes. Nurses may need to consider the sorbitol content of some liquid medications, for example, elixirs, as diarrhoea has been attributed to the sorbitol content of the elixir, not the drug itself. In addition, the use of 30 mL of water for irrigation when administering medications or flushing small-diameter nasoenteral tubes may reduce the number of tube occlusions.

2015-01-01

Introduction Radiofrequency ablation treatment of the tongue base can be used either alone or as part of a multilevel approach in the treatment of snoring. This involves the generation of thermal energy around the circumvallate papillae of the tongue. Potential complications include ulceration, dysphagia, haematoma and abscess formation. Presentation of case We present the case of a 50-year-old patient who developed an anterior neck swelling following a second application of radiofrequency ablation therapy to the tongue base for snoring. This was secondary to an infection of a previously undiagnosed thyroglossal cyst. The patient made a full recovery following intravenous antibiotic therapy and ultrasound-guided needle aspiration. Discussion Thyroglossal tract remnants are thought to be present in seven percent of the adult population. An infection in a thyroglossal tract cyst has not previously been reported following radiofrequency ablation of the tongue base. Given the relatively high complication rate of tongue base radiofrequency ablation in some series, this complication may be under-recognised. Conclusion An infected thyroglossal tract cyst should be suspected in patients with anterior neck swellings following radiofrequency ablation therapy to the tongue base. We advise caution when performing this procedure on patients with known thyroglossal tract remnants though there is insufficient evidence to suggest that this procedure is contraindicated.

Thrombophilia and Pregnancy Complications

Simcox, Louise E.; Ormesher, Laura; Tower, Clare; Greer, Ian A.

2015-01-01

There is a paucity of strong evidence associated with adverse pregnancy outcomes and thrombophilia in pregnancy. These problems include both early (recurrent miscarriage) and late placental vascular-mediated problems (fetal loss, pre-eclampsia, placental abruption and intra-uterine growth restriction). Due to poor quality case-control and cohort study designs, there is often an increase in the relative risk of these complications associated with thrombophilia, particularly recurrent early pregnancy loss, late fetal loss and pre-eclampsia, but the absolute risk remains very small. It appears that low-molecular weight heparin has other benefits on the placental vascular system besides its anticoagulant properties. Its use is in the context of antiphospholipid syndrome and recurrent pregnancy loss and also in women with implantation failure to improve live birth rates. There is currently no role for low-molecular weight heparin to prevent late placental-mediated complications in patients with inherited thrombophilia and this may be due to small patient numbers in the studies involved in summarising the evidence. There is potential for low-molecular weight heparin to improve pregnancy outcomes in women with prior severe vascular complications of pregnancy such as early-onset intra-uterine growth restriction and pre-eclampsia but further high quality randomised controlled trials are required to answer this question.

The cost of medical care and availability of resources (human and facilities) which differs from nation to nation are amongst others, factors driving medical tourism (MT) despite its potential drawbacks. The aim of the study was to analyse all patients that presented with neurosurgical complications following MT. A single institution prospective study was carried out. Data which included patients' demographics, diagnosis, Glasgow coma scale score at admission, type of complication, and outcome were collected over a 3 year period and analysed. A total of 23 neurosurgical cases were seen during the study period with a median age of 42 years (17-70 years). India is the most common country visited by Nigerian patients. Nine patients died from various complications on arrival in Nigeria. There was no significant statistical difference between the outcome and patients clinical status prior to travel (p=0.107), country where the surgery was done (p=0.776), admission GCS in Nigeria (p=0.169), and redo surgery in Nigeria (0.181). Government in different nations should have legislations to ensure that medical tourists' receive appropriate care abroad, proper follow-up care upon their return, and also promulgate laws to regulate quasi and organised MT agencies that are operating in a regulatory vacuum.

Abstract Significance: Recent clinical evidence identified anemia to be correlated with severe complications of cardiovascular disease (CVD) such as bleeding, thromboembolic events, stroke, hypertension, arrhythmias, and inflammation, particularly in elderly patients. The underlying mechanisms of these complications are largely unidentified. Recent Advances: Previously, red blood cells (RBCs) were considered exclusively as transporters of oxygen and nutrients to the tissues. More recent experimental evidence indicates that RBCs are important interorgan communication systems with additional functions, including participation in control of systemic nitric oxide metabolism, redox regulation, blood rheology, and viscosity. In this article, we aim to revise and discuss the potential impact of these noncanonical functions of RBCs and their dysfunction in the cardiovascular system and in anemia. Critical Issues: The mechanistic links between changes of RBC functional properties and cardiovascular complications related to anemia have not been untangled so far. Future Directions: To allow a better understanding of the complications associated with anemia in CVD, basic and translational science studies should be focused on identifying the role of noncanonical functions of RBCs in the cardiovascular system and on defining intrinsic and/or systemic dysfunction of RBCs in anemia and its relationship to CVD both in animal models and clinical settings.

Right lateral sector (RLS) grafting has been introduced to enlarge the potential donor pool for living donor liver transplantation (LDLT); however, evidence of its feasibility is limited. Data from 437 LDLTs carried out between 2000 and 2013 were analyzed retrospectively. LDLTs using a right liver graft (n = 251) were compared with those using a RLS graft (RLSG; n = 28). No donor mortality occurred, and the major complication rates were similar between the two groups. Postoperative liver function preservation was better in the RLSG donors. Concerning the recipients, the mortality and overall survival rates were similar between the two groups. The complication rate for the recipients was higher when more than two arterial or biliary anastomoses were necessary. A systematic literature search identified four reports on LDLT using RLSGs. Among 66 LDLTs, including the present series, there were no cases of donor death, and the rates of major and minor complications in the donors were 6% and 29%, respectively. The major complication and overall mortality rates in the recipients were 29% and 6%, respectively. LDLT using an RLSG is feasible, with an acceptable survival rate among the recipients. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Fatty liver diseases are complications of the metabolic syndrome associated with obesity, insulin resistance and low grade inflammation. Our aim was to uncover mechanisms contributing to hepatic complications in this setting. We used foz/foz mice prone to obesity, insulin resistance and progressive fibrosing non-alcoholic steatohepatitis (NASH). Foz/foz mice are hyperphagic but wild-type (WT)-matched calorie intake failed to protect against obesity, adipose inflammation and glucose intolerance. Obese foz/foz mice had similar physical activity level but reduced energy expenditure. Thermogenic adaptation to high-fat diet (HFD) or to cold exposure was severely impaired in foz/foz mice compared with HFD-fed WT littermates due to lower sympathetic tone in their brown adipose tissue (BAT). Intermittent cold exposure (ICE) restored BAT function and thereby improved glucose tolerance, decreased fat mass and liver steatosis. We conclude that failure of BAT adaptation drives the metabolic complications of obesity in foz/foz mice, including development of liver steatosis. Induction of endogenous BAT function had a significant therapeutic impact on obesity, glucose tolerance and liver complications and is a potential new avenue for therapy of non-alcoholic fatty liver disease (NAFLD). © 2017 The Author(s). published by Portland Press Limited on behalf of the Biochemical Society.

The immunoregulation to tolerate the semiallogeneic fetus during pregnancy includes a harmonious dynamic balance between anti- and pro-inflammatory cytokines. Several earlier studies reported significantly different levels and/or ratios of several cytokines in complicated pregnancy as compared to normal pregnancy. However, as cytokines operate in networks with potentially complex interactions, it is also interesting to compare groups with multi-cytokine data sets, with multivariate analysis. Such analysis will further examine how great the differences are, and which cytokines are more different than others. Various multivariate statistical tools, such as Cramer test, classification and regression trees, partial least squares regression figures, 2-dimensional Kolmogorov-Smirmov test, principal component analysis and gap statistic, were used to compare cytokine data of normal vs anomalous groups of different pregnancy complications. Multivariate analysis assisted in examining if the groups were different, how strongly they differed, in what ways they differed and further reported evidence for subgroups in 1 group (pregnancy-induced hypertension), possibly indicating multiple causes for the complication. This work contributes to a better understanding of cytokines interaction and may have important implications on targeting cytokine balance modulation or design of future medications or interventions that best direct management or prevention from an immunological approach. © 2018 The Authors.

Individuals living with an ostomy may suffer from a variety of peri-stomal skin complications related to the use of their stoma appliance or accessories. These conditions can be serious enough to significantly impact on a patient's quality of life and may result in severe clinical complications (such as infection). This article is a review of the literature with the objective of investigating and presenting evidence for the well-documented use of aloe vera in the prevention of skin conditions similar to those seen in peri-stomal skin complications. An exploration for the potential use of aloe vera directly or indirectly (as an adjunct to medical devices such as wafers) in stoma patients is presented with the view that this use may be beneficial in the prevention of such peri-stomal skin complications.

Comparison of complication outcomes in acute pancreatitis following ERCP and conservative management at UKM medical centre: a six years retrospective study.

Acute pancreatitis is one of the common reasons for surgical admission. It is a potentially lethal disease that is increasing in its incidence. The most common causes of acute pancreatitis is from gallstones and alcohol. Other causes of acute pancreatitis include hypertriglyceridaemia, hyperparathyroidism, pancreatic malignancy, Endoscopic retrograde cholangiopancreatography (ERCP), trauma, infectious agents, drugs, autoimmunity, and hereditary. The treatment of acute pancreatitis is mainly supportive. The complication of ERCP in acute pancreatitis can be divided into local complication (pancreatic abscess, pseudocyst), systemic complications (renal failure, respiratory failure, cardiogenic shock) and biliary sepsis (acute cholangitis and acute cholecystitis). However, early ERCP and possible sphincterotomy should be kept in mind for patients with severe disease and biliary obstruction who are not improving with medical therapy. This study is done to compare the complication rate of ERCP and conservative management in acute pancreatitis for past 6 years in Pusat Perubatan UKM. The study is conducted retrospectively and the study population was from January 2003 until December 2008. About 100 patients involving 51 males and 49 females were included in this study. All of them were diagnosed acute pancreatitis based on the serum amylase level of 4 times than normal value detected from Chemistry Pathology record, Pathology Department, PPUKM. Then, data were collected from the patient's file which include the demographic data and patient clinical presentation, ultrasound finding, either patient went for ERCP within 72 hours or not. If ERCP not done within 72 hours of admission then it will considered that the patient is under conservative management. From 100 patients that involved in this study about 44% was Malay, 36 % was Chinese, 18 % was Indian and the other 2 % was from other origin. There were 28 cases (28%) where ERCP was done within 72 hours, and the other 72 cases (72%) the treatment was conservative. Among 28 cases that ERCP was done within 72 hours after admission, 20 cases are mild where as only 8 cases are severe. However, in conservative group about 56 cases are mild and the other 16 are severe. Among the conservative group there are 12 cases which have complications. The complications are respiratory failure, renal failure, sepsis, shock and pancreatic necrosis. There are 7 cases whose have respiratory failure alone, 1 case developed renal failure and 1 case has a shock. 1 case developed both pancreatic necrosis with sepsis. 1 case each developed respiratory failure with sepsis and respiratory failure with renal failure. However no complications were noted in early ERCP group. As a conclusion in this study we found out that early ERCP have a significant role in acute pancreatitis compare to conservative management.

Since the first deep brain stimulation (DBS) performed for movement disorder more than a decade ago, DBS has become a standard operation for advanced Parkinson's disease. Its indications are expanding to areas of dystonia, psychiatric conditions and refractory epilepsy. Additionally, a new set of DBS-related complications have arisen. Many teams found a slow learning curve from this complication-prone operation. We would like to investigate complications arising from 100 DBS electrode insertions and its prevention. We performed an audit in all DBS patients for operation-related complications in our centre from 1997 to 2008. Complications were classified into operation-related, hardware-related and stimulation-related. Operation-related complications included intracranial haemorrhages and electrode malposition. Hardware-related complications included fracture of electrodes, electrode migration, infection and erosion. Stimulation-related complications included sensorimotor conditions, psychiatric conditions and life-threatening conditions. From 1997 to the end of 2008, 100 DBS electrodes were inserted in 55 patients for movement disorders, mostly for Parkinsons disease (50 patients). There was one symptomatic cerebral haemorrhage (1%) and two electrode malpositions (2%). Meticulous surgical planning, use of microdriver and a reliable electrode anchorage device would minimise this group of complications. There were two electrode fractures, one electrode migration and one pulse-generator infection which contributed to the hardware-related complication rate of 5%. There were no sensorimotor or life-threatening complications in our group. However, three patients suffered from reversible psychiatric symptoms after DBS. DBS is, on the one hand, an effective surgical treatment for movement disorders. On the other hand, it is a complication-prone operation. A dedicated "Movement Disorder Team" consisting of neurologists, neurophysiologists, functional neurosurgeons, neuropsychologists and nursing specialists is essential. Liaison among team members in peri-operative periods and postoperative care is the key to avoiding complications and having a successful patient outcome.

All persons with an ostomy are at risk for development of peristomal skin problems. This is true regardless of the person's nation of residence, type of stoma, or supplies available for stoma care. There are measures that can be taken to lessen the potential for peristomal skin problems. These measures include preoperative stoma site marking, preoperative education, appropriate pouch/barrier fitting, and pouch maintenance. The 2014 World Council of Enterostomal Therapists International Ostomy Guideline includes recommendations that can be implemented to prevent situations that may lead to peristomal skin complications.

Abnormal placentation is a common pathogenic mechanism of many placenta-mediated complications of late pregnancy, including pre-eclampsia, fetal growth restriction, stillbirth, and placental abruption. During successful placentation, the trophoblast (which is a semi-allograft) is not rejected by decidual immune cells because of maternal immune tolerance, mainly induced by human leukocyte antigen G (HLA-G). Deficient HLA-G expression seems to be associated with the development of complications of pregnancy. The aim of this study was to determine whether low soluble HLA-G (sHLA-G) levels in maternal blood at the beginning of pregnancy may be associated with subsequent placenta-mediated complications. For this retrospective case-control study, 117 cases of placenta-mediated complications of pregnancy and 234 controls with uneventful pregnancy were selected. Plasma sHLA-G levels were measured at 11-13 weeks' gestation by the enzyme-linked immunosorbent assay method in blood samples previously obtained at first-trimester prenatal screening for chromosomal fetal abnormalities. Women who subsequently developed placenta-mediated complications had significantly lower sHLA-G levels at the beginning of pregnancy (median, 43.08 IU/mL) than controls (median, 49.10 IU/mL; P = 0.008). An sHLA-G level lower than 43.50 IU/mL at the end of the first trimester was associated with a twofold increased risk of developing a pregnancy complication (odds ratio, 1.82; 95% confidence interval, 1.22-2.73). The strongest association, although only moderately strong, was observed with severe pre-eclampsia (odds ratio, 2.66; 95% confidence interval, 1.08-6.56). Placenta-mediated complications of pregnancy may be associated with low sHLA-G levels in the first trimester, suggesting a potential role of sHLA-G in the early stages of placentation. © 2017 Japan Society of Obstetrics and Gynecology.

Complications associated with radiofrequency ablation of pulmonary veins.

Madrid Pérez, J M; García Barquín, P M; Villanueva Marcos, A J; García Bolao, J I; Bastarrika Alemañ, G

Radiofrequency ablation is an efficacious alternative in patients with symptomatic atrial fibrillation who do not respond to or are intolerant to at least one class I or class III antiarrhythmic drug. Although radiofrequency ablation is a safe procedure, complications can occur. Depending on the location, these complications can be classified into those that affect the pulmonary veins themselves, cardiac complications, extracardiac intrathoracic complications, remote complications, and those that result from vascular access. The most common complications are hematomas, arteriovenous fistulas, and pseudoaneurysms at the puncture site. Some complications are benign and transient, such as gastroparesis or diaphragmatic elevation, whereas others are potentially fatal, such as cardiac tamponade. Radiologists must be familiar with the complications that can occur secondary to pulmonary vein ablation to ensure early diagnosis and treatment. Copyright © 2016 SERAM.

Objective To evaluate visual outcomes and potential complications for optic nerve decompression using an endoscopic endonasal approach (EEA) for fibrous dysplasia. Design Retrospective chart review of patients with fibrous dysplasia causing extrinsic compression of the canalicular segment of the optic nerve that underwent an endoscopic endonasal optic nerve decompression at the University of Pittsburgh Medical Center from 2010 to 2013. Main Outcome Measures The primary outcome measure assessed was best-corrected visual acuity (BCVA) with secondary outcomes, including visual field testing, color vision, and complications associated with the intervention. Results A total of four patients and five optic nerves were decompressed via an EEA. All patients were symptomatic preoperatively and had objective findings compatible with compressive optic neuropathy: decreased visual acuity was noted preoperatively in three patients while the remaining patient demonstrated an afferent pupillary defect. BCVA improved in all patients postoperatively. No major complications were identified. Conclusion EEA for optic nerve decompression appears to be a safe and effective treatment for patients with compressive optic neuropathy secondary to fibrous dysplasia. Further studies are required to identify selection criteria for an open versus an endoscopic approach. PMID:28180039

Gastrointestinal surgery is associated with a high incidence of infectious complications. Selective decontamination of the digestive tract is an antimicrobial prophylaxis regimen that aims to eradicate gastrointestinal carriage of potentially pathogenic microorganisms and represents an adjunct to regular prophylaxis in surgery. Relevant studies were identified using bibliographic searches of MEDLINE, EMBASE, and the Cochrane database (period from 1970 to November 1, 2012). Only studies investigating selective decontamination of the digestive tract in gastrointestinal surgery were included. Two randomized clinical trials and one retrospective case-control trial showed significant benefit in terms of infectious complications and anastomotic leakage in colorectal surgery. Two randomized controlled trials in esophageal surgery and two randomized clinical trials in gastric surgery reported lower levels of infectious complications. Selective decontamination of the digestive tract reduces infections following esophageal, gastric, and colorectal surgeries and also appears to have beneficial effects on anastomotic leakage in colorectal surgery. We believe these results provide the basis for a large multicenter prospective study to investigate the role of selective decontamination of the digestive tract in colorectal surgery.

Objective: To introduce new corneal high-speed, ultra–high-resolution optical coherence tomography (hsUHR-OCT) technology that improves the evaluation of complicated and uncomplicated cataract, corneal, and refractive surgical procedures. Design: This case series included a control subject and 9 eyes of 8 patients who had undergone phacoemulsification, Descemet membrane stripping endokeratoplasty, corneal implantation for keratoconus, and complicated and uncomplicated laser in situ keratomileusis. These eyes underwent imaging using a prototype ophthalmic hsUHR-OCT system. All the scans were compared with conventional slitlamp biomicroscopy. Results: Cross-sectional hsUHR-OCT imaging allowed in vivo differentiation of corneal layers and existing pathologic abnormalities at ultrahigh axial image resolution. These images illustrate the various incisional and refractive interfaces created with corneal procedures. Conclusions: The magnified view of the cornea using hsUHR-OCT is helpful in conceptualizing and understanding basic and complicated clinical pathologic features; hsUHR-OCT has the potential to become a powerful, noninvasive clinical corneal imaging modality that can enhance surgical management.

Since the first intravenous nutrition support attempt with olive oil in the 17th century, intravenous fat emulsions (IVFEs) have evolved to become an integral component in the management of patients receiving home parenteral nutrition (HPN). IVFEs serve as a calorie source and provide essential fatty acids (linoleic acid and α-linolenic acid) in patients unable to achieve adequate intake of these fatty acids through alternative means. However, IVFE use is also associated with multiple complications, including increased infection risk, liver disease, and systemic proinflammatory states. In the United States, most IVFEs are composed of 100% soybean oil; internationally multiple alternative IVFEs (using fish oil, olive oil, and long- and medium-chain triglycerides) are available or being developed. The hope is that these IVFEs will prevent, or decrease the risk of, some of the HPN-associated complications. The goal of this article is to review how IVFEs came into use, their composition and metabolism, options for IVFE delivery in HPN, benefits and risks of IVFE use, and strategies to minimize the risks associated with IVFE use in HPN patients. © 2016 American Society for Parenteral and Enteral Nutrition.

Bilateral tension pneumothorax after acupuncture.

Acupuncture is an ancient complementary medicine which is currently used worldwide. Many serious adverse events have been reported which include a spectrum of mild-to-fatal complications. However, the level of awareness with regard to complications is still low both to physicians and patients. We report a 63-year-old who presented with acute shortness of breath 2 hours after having had acupuncture. On examination, there was absent breath sound heard on the left lung and slightly reduced breath sound on the right lung. She had type 1 respiratory failure. Urgent chest radiograph confirmed bilateral pneumothorax which was more severe on the left with tension pneumothorax and mediastinal shift. Chest tubes were inserted bilaterally after failed needle aspiration attempts. Subsequently, the pneumothoraces resolved, and she was discharged well. The bilateral pneumothoraces caused by acupuncture were curable but could have been potentially fatal if diagnosis was delayed. This case report adds to the limited current literature on the complications of acupuncture leading to bilateral pneumothoraces. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Occurrence of congenital, cardiovascular, visceral, neurologic, and neuro-ophthalmologic complications in late yaws: a theme for future research.

PubMed

Román, G C; Román, L N

1986-01-01

Late lesions of yaws are thought to be limited to skin, bones and joints, without congenital, visceral, or central nervous system (CNS) involvement. However, the treponemes isolated from patients with yaws, endemic syphilis, and venereal syphilis are genetically identical subspecies of Treponema pallidum. The controversy surrounding distinctions between syphilis and yaws is presented in its historical context, and reports of congenital, visceral, and CNS complications of yaws are reviewed. Isolation of treponemes from aqueous humor, as well as CSF abnormalities in 24.9% of 902 patients with yaws, indicate the existence of CNS involvement. The high prevalence of tropical myeloneuropathies of unknown origin discovered in areas of previous treponemal endemicity, particularly in Jamaica and Colombia, may represent late complications of yaws. Careful analysis of the collected evidence indicates that potential sequelae of yaws include congenital, visceral, and tertiary CNS lesions identical to those of venereal syphilis. The current worldwide resurgence of endemic treponematoses provides an unparalleled opportunity to settle conclusively questions still unanswered regarding the natural history of these infections.

Traumatic rib fractures can cause chest complications that need further treatment and hospitalization. We hypothesized that an increase in the number of displaced rib fractures will be accompanied by an increase in chest complications. We retrospectively reviewed the trauma registry between January 2013 and May 2015 in a teaching hospital in northeastern Taiwan. Patients admitted with chest trauma and rib fractures without concomitant severe brain, splenic, pelvic or liver injuries were included. The demographic data, such as gender, age, the index of coexistence disease, alcohol consumption, trauma mechanisms were analyzed as potential predictors of pulmonary complications. Pulmonary complications were defined as pneumothorax, hemothorax, flail chest, pulmonary contusion, and pneumonia. In the 29 months of the study period, a total of 3151 trauma patients were admitted to our hospital. Among them, 174 patients were enrolled for final analysis. The most common trauma mechanism was road traffic accidents (58.6%), mainly motorbike accidents (n = 70, 40.2%). Three or more displaced rib fractures had higher specificity for predicting complications, compared to three or more total rib fractures (95.5% vs 59.1%). Adjusting the severity of chest trauma using TTSS and Ribscore by multivariable logistic regression analysis, we found that three or more rib fractures or any displaced rib fracture was the most significant predictor for developing pulmonary complication (aOR: 5.49 95% CI: 1.82-16.55). Furthermore, there were 18/57 (31.6%) patients with fewer than three ribs fractures developed pulmonary complications. In these 18 patients, only five patients had delayed onset complications and four of them had at least one displaced rib fracture. In this retrospective cohort study, we found that the number of displaced or total rib fractures, bilateral rib fractures, and rib fractures in more than two areas were associated with the more chest complications. Furthermore, three or more rib fracture or any displacement were found to be the most sensitive risk factor for chest complications, independent of other risk factors or severity index. The number of displaced rib fractures could be a strong predictor for developing pulmonary complications. For patients with fewer than three rib fractures without rib displacement and initial lung or other organ injuries, outpatient management could be safe and efficient.

Purpose: Duputren’s contracture (DC) is a benign disease characterized by abnormal thickening of the fascial surfaces of the hands or feet causing curling of the surface, functional impairment, weakness, and pain. The purpose of the investigation is to describe the radiation treatment approaches, compare these techniques, and discuss the potential side effects and complications of these techniques. Methods: Early stage DC has been treated with 120 kVp X rays but also with high-energy electrons or photons. High-energy electrons have been the radiation of choice but severe contracture of the hand makes it difficult to produce a plan with acceptable dosemore » uniformity. High-energy photons can overcome this difficulty either by directing a beam onto the palmer or back of the surface of the hand, including bolus to maximize the surface dose. We calculated the dose to the bone for the 120 kVp treatment using published %DD data and mass energy absorption coefficients for bone and muscle. Results: The dose to underlying bone from megavoltage photons and electrons is essentially the same, but dose to the bone for using 120 kVp can be 4–5 times greater due to the photoelectric effect. For the 30 Gy dose deliver using this technique, the dose to the bone could be 84–105 Gy after taking the penetration of the beam into account. After radiotherapy, there is often decreased osteoblastic activity and vascular fibrosis that leads to osteitis, atrophy, and decreased metabolic bone activity. Incidence of fractures occurs routinely above 60 Gy with higher doses potentially leading to higher incidences of bone complications. Conclusion: Radiation therapy for DC using low-energy X rays can deliver a prohibitively high dose to the underlying bone potentially leading to severe bone complications.« less

Cancer anorexia-cachexia syndrome (CACS) is a complex and largely untreatable paraneoplastic complication common in advanced cancer. It is associated with profoundly deleterious effects on quality of life and survival. Since its discovery over a decade ago, anamorelin hydrochloride (anamorelin), a mimetic of the growth hormone secretagogue ghrelin, has shown considerable promise in ameliorating components of CACS when administered to patients with advanced cancer, including loss of lean body mass and reversal of anorexia. This review summarizes the development of anamorelin and its safety and efficacy in clinical investigations. The potential future role of anamorelin in treating CACS is also discussed.

Arthroscopic shoulder stabilization offers several potential advantages compared with open surgery, including the opportunity to more accurately evaluate the glenohumeral joint at the time of diagnostic assessment; comprehensively address multiple pathologic lesions that may be identified; and avoid potential complications unique to open stabilization, such as postoperative subscapularis failure. A thorough understanding of normal shoulder anatomy and biomechanics, along with the pathoanatomy responsible for anterior, posterior, and multidirectional shoulder instability patterns, is very important in the management of patients who have shoulder instability. The treating physician also must be familiar with diagnostic imaging and physical examination maneuvers that are required to accurately diagnose shoulder instability.

Nonalcoholic fatty liver disease (NAFLD) is highly common and potentially serious in children and adolescents. The term NAFLD refers to a spectrum of diseases ranging from accumulation of fat in the liver (simple steatosis or nonalcoholic fatty liver "NAFL") to the potentially progressive form of nonalcoholic steatohepatitis (NASH) characterized by hepatocyte ballooning, inflammation, and often associated with fibrosis. While large prospective longitudinal studies in pediatric NAFLD are still lacking, growing evidence suggests that children with NAFL are at increased risk for cardiometabolic complications, while those with NASH and advance fibrosis are also at risk for significant liver-related morbidity including cirrhosis and its complications. Pediatric NAFLD shares features of adult NAFLD but also shows many different characteristics in terms of prevalence, histology, diagnosis and management. Translational studies suggest that NAFLD is a highly heritable disease in which genetic variations and environment closely interact to determine the disease phenotype and the progression to the more advanced forms of the disease. Changes in lifestyle, targeting gradual weight reduction, and physical exercise continue to be the mainstay of treatment for NAFLD in children. Recent advances in development of noninvasive diagnostic modalities and the potential for identifying effective pharmacological interventions may result in significant progress in the management of NAFLD in the pediatric population.

Extracellular vesicles (EVs) represent a heterogeneous population of small vesicles, consisting of a phospholipidic bilayer surrounding a soluble interior cargo. Almost all cell types release EVs, thus they are naturally present in all body fluids. Among the several potential applications, EVs could be used as drug delivery vehicles in disease treatment, in immune therapy because of their immunomodulatory properties and in regenerative medicine. In addition to general markers, EVs are characterized by the presence of specific biomarkers (proteins and miRNAs) that allow the identification of their cell or tissue origin. For these features, they represent a potential powerful diagnostic tool to monitor state and progression of specific diseases. A large body of studies supports the idea that endothelial derived (EMPs) together with platelet-derived microparticles (PMPs) are deeply involved in the pathogenesis of diseases characterized by micro- and macrovascular damages, including diabetes. Existing literature suggests that the detection of circulating EMPs and PMPs and their specific miRNA profile may represent a very useful non-invasive signature to achieve information on the onset of peculiar disease manifestations. In this review, we discuss the possible utility of EVs in the early diagnosis of diabetes-associated microvascular complications, specifically related to kidney.

The reported rate of complications of reverse shoulder arthroplasty (RSA) seems to be higher than the complication rate of anatomical total shoulder arthroplasty. The reported overall complication rate of primary RSA is approximately 15%; when RSA is used in the revision setting, the complication rate may approach 40%. The most common complications of RSA include instability, infection, notching, loosening, nerve injury, acromial and scapular spine fractures, intra-operative fractures and component disengagement. Careful attention to implant design and surgical technique, including implantation of components in the correct version and height, selection of the best glenosphere-humeral bearing match, avoidance of impingement, and adequate management of the soft tissues will hopefully translate in a decreasing number of complications in the future.

Capsule retention is a potential complication of capsule endoscopy (CE). The aims of our study were to determine the incidence of capsule retention in pediatric patients undergoing CE and to identify potential risk factors for capsule retention. We performed an institutional review board-approved retrospective chart review of pediatric patients undergoing CE studies at a single center. Data collected included patient age, sex, prior diagnosis of inflammatory bowel disease (IBD), CE indication, prior small bowel series results, study result, and complications. Two hundred seven CE procedures were performed in pediatric patients during the study period. Capsule retention occurred in 3 (1.4%) of the 207 studies. All 3 patients had known Crohn disease (CD). The risk of capsule retention in pediatric patients with known IBD was 5.2% (3/58). The risk of capsule retention for patients with suspected IBD and all other indications was 0%. If small bowel disease was identified on upper gastrointestinal series in patients with known CD, then the risk of capsule retention was 37.5% (3/8). Only 7 patients with known IBD had a body mass index (BMI) below the 5th percentile. Of these 7 patients, 3 (43%) had capsule retention. Red flags for potential CE retention identified in our study include known IBD (5.2% retention risk), previous small bowel follow-through demonstrating small bowel CD (37.5% retention risk), and BMI <5th percentile with known IBD (43% retention risk). Caution is advised in these pediatric patients before capsule ingestion.

X-linked hypophosphatemia (XLH) is a group of rare disorders caused by defective proximal tubular reabsorption of phosphate. Mutations in the PHEX gene are responsible for the majority of cases. There are very few reports of long-term complications of XLH other than skeletal and dental diseases. The aim of this study was to identify the phenotypic presentation of XLH during adulthood including complications other than skeletal and dental diseases. The clinical and biochemical phenotype of 22 adult patients with a PHEX gene mutation were examined retrospectively from their medical records. 6 patients had hypertension. The average age of hypertension onset was 29.0 years. Secondary hyperparathyroidism preceded the development of hypertension in 5 patients. 1 patient developed tertiary hyperparathyroidism. 15 patients had nephrocalcinosis. 2 patients had chronic renal dysfunction. Patients with hypertension had a significantly lower eGFR (p=0.010) compared to patients without hypertension. No significant difference was found in any other parameters. To examine the genotype-phenotype correlation, 10 adult males were chosen for analysis. No significant genotype-phenotype correlation analysis was revealed in any of the complications. However, there was a possibility that the age at nephrocalcinosis onset was younger in the non-missense mutation group than in the missense mutation group (p=0.063). This study corroborated the view that early-onset hypertension could be one of the characteristic complications seen in XLH patients. Considering the limited number of our patients, further study is necessary to address a potential cause of hypertension. XLH patients require careful lifelong treatment.

Dacryocystorhinostomy (DCR) can be performed via an external or endoscopic approach. The use of ultrasonic or piezosurgery has been well described for endoscopic DCRs but is lacking for external DCRs. This study presents a case series of external DCRs performed using piezosurgery evaluating results and complications. Prospective, consecutive case series of patients undergoing primary external DCR for lacrimal drainage insufficiency. A standard external DCR technique was used using 1 of 2 piezosurgery systems for all bone incision. All patients received silicone intubation to the lacrimal system. Surgical outcome was measured in terms of patient-reported epiphora as follows: 1) complete resolution, 2) improvement >50%, 3) improvement <50%, and 4) No improvement. Intra and postoperative complications were also recorded. Fifty-two patients, 14 male and 38 female, were included in the study, with 2 patients having bilateral surgery. The average age of the patients was 55.8 years. The average length of follow up was 221 days. Surgical outcomes showed 72% of patients with complete resolution of epiphora and 21% with >50% improvement. There were 4 patients (7%) who had <50% improvement. There was 1 (2%) intraoperative complication and 2 (4%) postoperative complications recorded. Piezourgery is a viable modality for performing external DCRs. The lack of surgical complications shows a potential for decreased soft tissues damage. The surgical success rate based on patient-reported epiphora is similar to those published for mechanical external DCRs. This modality may benefit the novice surgeon in the reduction of soft and mucosal tissue damage.

Periodontal plastic procedures are performed to prevent or correct anatomical, developmental, traumatic, or plaque induced defects of the gingiva, alveolar mucosa, or bone. The majority of these procedures are performed in combination with restorative and/or orthodontic therapy with the primary goal of enhancing aesthetics. In this review some of the more prominent techniques currently available to address mucogingival deficiencies including pedicle grafts, free soft tissue grafts, and combination grafts are illustrated. In addition, potential complications associated with periodontal plastic procedures are discussed.

Deferoxamine mesylate (DFO) reduces morbidity and mortality associated with transfusional iron overload. Data on the utilization and costs of care among U.S. patients receiving DFO in typical clinical practice are limited however. This was a retrospective study using a large U.S. health insurance claims database spanning 1/97-12/04 and representing 40 million members in >70 health plans. Study subjects (n = 145 total, 106 sickle cell disease [SCD], 39 thalassemia) included members with a diagnosis of thalassemia or SCD, one or more transfusions (whole blood or red blood cells), and one or more claims for DFO. Mean transfusion episodes were 12 per year. Estimated mean DFO use was 307 g/year. Central venous access devices were required by 20% of patients. Cardiac disease was observed in 16% of patients. Mean total medical costs were $59,233 per year including $10,899 for DFO and $8,722 for administration of chelation therapy. In multivariate analyses, potential complications of iron overload were associated with significantly higher medical care costs. In typical clinical practice, use of DFO in patients with thalassemia and SCD receiving transfusions is low. Administration costs represent a large proportion of the cost of chelation therapy. Potential complications of iron overload are associated with increased costs. (c) 2007 Wiley-Liss, Inc.

Esophageal surgery in minimally invasive era

2016-01-01

The widespread popularity of new surgical technologies such as laparoscopy, thoracoscopy and robotics has led many surgeons to treat esophageal diseases with these methods. The expected benefits of minimally invasive surgery (MIS) mainly include reductions of postoperative complications, length of hospital stay, and pain and better cosmetic results. All of these benefits could potentially be of great interest when dealing with the esophagus due to the potentially severe complications that can occur after conventional surgery. Moreover, robotic platforms are expected to reduce many of the difficulties encountered during advanced laparoscopic and thoracoscopic procedures such as anastomotic reconstructions, accurate lymphadenectomies, and vascular sutures. Almost all esophageal diseases are approachable in a minimally invasive way, including diverticula, gastro-esophageal reflux disease, achalasia, perforations and cancer. Nevertheless, while the limits of MIS for benign esophageal diseases are mainly technical issues and costs, oncologic outcomes remain the cornerstone of any procedure to cure malignancies, for which the long-term results are critical. Furthermore, many of the minimally invasive esophageal operations should be compared to pharmacologic interventions and advanced pure endoscopic procedures; such a comparison requires a difficult literature analysis and leads to some confounding results of clinical trials. This review aims to examine the evidence for the use of MIS in both malignancies and more common benign disease of the esophagus, with a particular emphasis on future developments and ongoing areas of research.

An occurrence of sepsis during inpatient fecal disimpaction.

Functional constipation is a common pediatric problem that is often treated through well-established algorithms. Fecal disimpaction is the initial therapeutic step, and severe cases require hospitalization for intensive therapies. We describe a significant unexpected complication of this common clinical situation. An 8-year-old boy with suspected chronic functional constipation was hospitalized for disimpaction by continuous nasogastric administration of polyethylene glycol electrolyte (PEG-E) solution. On the sixth day of disimpaction, the patient abruptly developed fever, tachycardia, and tachypnea. Evaluation included blood culture, which grew Escherichia coli, and treatment with a course of appropriate antibiotics was provided. The safety of PEG-E solutions has been shown in studies of children with constipation, which made this patient's illness surprising. Several potential etiologies of his infection were considered, including bacterial translocation (BT). BT is defined as the passage of live microbes and microbial products from the gastrointestinal tract to extraintestinal sites, such as the bloodstream. It has been shown to occur in a variety of clinical conditions but is of unclear clinical significance. In this case, physical damage to the intestinal mucosa was thought to contribute to the potential occurrence of BT, and prolonged disimpaction was considered as a risk factor. E coli sepsis in a child undergoing inpatient nasogastric fecal disimpaction with PEG-E represents a clinical problem never before reported in the literature and should increase clinicians' indices of suspicion for uncommon complications of common procedures.

The spread of artemisinin-resistant parasites could lead to higher incidence of patients with malaria complications. However, there are no current treatments that directly dislodge sequestered parasites from the microvasculature. We show that four common antiplasmodial drugs do not disperse rosettes (erythrocyte clusters formed by malaria parasites) and therefore develop a cell-based high-throughput assay to identify potential rosette-disrupting compounds. A pilot screen of 2693 compounds identified Malaria Box compound MMV006764 as a potential candidate. Although it reduced rosetting by a modest 20%, MMV006764 was validated to be similarly effective against both blood group O and A rosettes of three laboratory parasite lines. Coupled with its antiplasmodial activity and drug-likeness, MMV006764 represents the first small-molecule compound that disrupts rosetting and could potentially be used in a resource-limited setting to treat patients deteriorating rapidly from malaria complications. Such dual-action drugs that simultaneously restore microcirculation and reduce parasite load could significantly reduce malaria morbidity and mortality. PMID:27403804

Quantum geometry of resurgent perturbative/nonperturbative relations

Basar, Gökçe; Dunne, Gerald V.; Ünsal, Mithat

2017-05-01

For a wide variety of quantum potentials, including the textbook `instanton' examples of the periodic cosine and symmetric double-well potentials, the perturbative data coming from fluctuations about the vacuum saddle encodes all non-perturbative data in all higher non-perturbative sectors. Here we unify these examples in geometric terms, arguing that the all-orders quantum action determines the all-orders quantum dual action for quantum spectral problems associated with a classical genus one elliptic curve. Furthermore, for a special class of genus one potentials this relation is particularly simple: this class includes the cubic oscillator, symmetric double-well, symmetric degenerate triple-well, and periodic cosine potential. These are related to the Chebyshev potentials, which are in turn related to certain \\mathcal{N} = 2 supersymmetric quantum field theories, to mirror maps for hypersurfaces in projective spaces, and also to topological c = 3 Landau-Ginzburg models and `special geometry'. These systems inherit a natural modular structure corresponding to Ramanujan's theory of elliptic functions in alternative bases, which is especially important for the quantization. Insights from supersymmetric quantum field theory suggest similar structures for more complicated potentials, corresponding to higher genus. Our approach is very elementary, using basic classical geometry combined with all-orders WKB.

Ranulas are cystic lesions in the floor of the mouth. They are either retention cysts of the excretory duct of the sublingual gland or pseudocysts formed by excretory duct rupture followed by extravasation and accumulation of mucus in the surrounding tissue. We report the case of a premature newborn with a congenital ranula in the floor of mouth. The ranula caused no discomfort or complications, so that immediate intervention was not necessary. The cyst resolved completely by the age of 4 months. Complications in newborns especially include airway obstruction and feeding difficulties. Surgical treatment options are needle aspiration, excision of the ranula, marsupialization, cryosurgery, and--in addition to excision of the cyst--removal of the ipsilateral sublingual gland. Sclerotherapy has shown good results as well. As many congenital cysts resolve or rupture spontaneously, they should be observed for potential resolution for several months in uncomplicated cases.

[Current management of thalassemia intermedia].

Thalassemia intermedia is a clinical entity where anemia is mild or moderate, requiring no or occasional transfusion. Non-transfusion-dependent thalassemia encompasses 3 main clinical forms: beta-thalassemia intermedia, hemoglobin E/beta-thalassemia and alpha-thalassemia intermedia (HbH disease). Clinical severity of thalassemia intermedia increases with age, with more severe anemia and more frequent complications such as extramedullary hematopoiesis and iron overload mainly related to increased intestinal absorption. Numerous adverse events including pulmonary hypertension and hypercoagulability have been associated with splenectomy, often performed in thalassemia intermedia patients. The potential preventive benefit of transfusion and chelation therapies on the occurrence of numerous complications supports the strategy of an earlier therapeutic intervention. Increasing knowledge about pathophysiological mechanisms involved in thalassemia erythropoiesis and related iron overload is currently translating in novel therapeutic approaches.

Phlebitis is a very common complication of the use of intravenous catheters. Two patients with an i.v. catheter complicated by thrombophlebitis are described. Patient A was immunocompromised due to chronic lymphatic leukaemia and developed septic thrombophlebitis with positive blood cultures for S. Aureus. Patient B was being treated with flucloxacillin because of an S. Aureus infection and developed chemical phlebitis. Septic phlebitis is rare, but potentially serious. Chemical or mechanical types of thrombophlebitis are usually less severe, but happen very frequently. Risk factors include: female sex, previous episode of phlebitis, insertion at (ventral) forearm, emergency placement and administration of antibiotics. Until recently, routine replacement of peripheral intravenous catheters after 72-96 h was recommended, but randomised controlled trials have not shown any benefit of this routine. A recent Cochrane Review recommends replacement of peripheral intravenous catheters when clinically indicated only.

ABSTRACT Heart transplantation is currently the definitive gold standard surgical approach in the treatment of refractory heart failure. However, the shortage of donors limits the achievement of a greater number of heart transplants, in which the use of mechanical circulatory support devices is increasing. With well-established indications and contraindications, as well as diagnosis and treatment of rejection through defined protocols of immunosuppression, the outcomes of heart transplantation are very favorable. Among early complications that can impact survival are primary graft failure, right ventricular dysfunction, rejection, and infections, whereas late complications include cardiac allograft vasculopathy and neoplasms. Despite the difficulties for heart transplantation, in particular, the shortage of donors and high mortality while on the waiting list, in Brazil, there is a great potential for both increasing effective donors and using circulatory assist devices, which can positively impact the number and outcomes of heart transplants.

2018-01-01

Diabetes Mellitus (DM) is a metabolic disorder characterized by chronic hyperglycaemia, which is attributed to several life threatening complications including atherosclerosis, nephropathy, and retinopathy. The current therapies available for the management of DM mainly include oral antidiabetic drugs and insulin injections. However, continuous use of synthetic drugs provides lower healing with many side effects. Therefore, there is an urge for safe and efficient antidiabetic drugs for the management of DM. In the continuing search for effective antidiabetic drugs, marine algae (seaweeds) remains as a promising source with potent bioactivity. It is anticipated that the isolation, characterization, and pharmacological study of unexplored marine algae can be useful in the discovery of novel antidiabetic compounds with high biomedical value. Among marine algae, brown and red algae are reported to exhibit antidiabetic activity. Majority of the investigations on algal derived compounds controls the blood glucose levels through the inhbition of carbohydrate hydroloyzing enzymes and protein tyrosine phosphatase 1B enzymes, insulin sensitization, glucose uptake effect and other protective effects against diabetic complications. Based on the above perspective this review provides; profiles for various marine algae posessing antidiabetic activity. This study also highlights the therapeutic potential of compounds isolated from marine algae for the effective management of diabetes and its associated complications.

Cardiovascular disease in recent onset diabetes mellitus.

Yamagishi, Shoichi

2011-05-01

Diabetes is associated with a marked increased risk of atherosclerotic vascular disorders, including coronary, cerebrovascular, and peripheral artery disease. Cardiovascular disease (CVD) could account for disabilities and high mortality rates in patients with diabetes. Conventional risk factors, including hyperlipidemia, hypertension, smoking, obesity, lack of exercise, and a positive family history, contribute similarly to macrovascular complications in type 2 diabetic patients and non-diabetic subjects. The levels of these factors in diabetic patients are certainly increased, but not enough to explain the exaggerated risk for macrovascular complications in the diabetic population. Furthermore, recently, macrovascular complications of diabetes have been shown to start before the onset of diabetes. Indeed, several clinical studies have confirmed the increased risk of CVD in patients with impaired glucose tolerance (IGT). Since insulin resistance-related postprandial metabolic derangements are thought to play a central role in the development and progression of CVD in patients with IGT, amelioration of postprandial metabolic disturbance is a therapeutic target for the prevention of CVD in these high-risk patients. Therefore, in this paper, we review the molecular mechanisms for the increased risk of CVD in recent onset diabetes mellitus, especially focusing on postprandial dysmetabolism. We also discuss here the potential therapeutic strategies that specially target the mechanisms responsible for vascular alterations in diabetes. Copyright © 2011 Japanese College of Cardiology.

Heroin Contaminated with Fentanyl Dramatically Enhances Brain Hypoxia and Induces Brain Hypothermia.

2017-01-01

While opioid abuse is an established medical and public health issue, the increased availability of highly potent synthetic opioids, such as fentanyl, has given rise to acute health complications, including a comatose state and death during drug overdose. Since respiratory depression that leads to acute hypoxia is the most dangerous complication of opioid drug use, we examined the effects of intravenous heroin and heroin contaminated with 10% fentanyl on oxygen levels in the nucleus accumbens (NAc) monitored using high-speed amperometry in freely moving rats. Additionally, we examined the effects of heroin, fentanyl, and their mixture on locomotion and temperatures in the NAc, temporal muscle, and skin. Both fentanyl and heroin at human-relevant doses (400 and 40 μg/kg, respectively) induced rapid, strong and transient decreases in NAc oxygen, indicative of brain hypoxia. When the heroin-fentanyl mixture was injected, the NAc hypoxic response was greatly potentiated in its duration, suggesting sustained hypoxia. In contrast to modest, monophasic brain temperature increases caused by heroin alone, the heroin-fentanyl mixture induced a biphasic temperature response, with a prominent postinjection decrease resulting from peripheral vasodilation. This hypothermic effect, albeit much smaller and more transient, was typical of fentanyl injected alone. Our findings indicate that accidental use of fentanyl instead of heroin, or even a relatively minor contamination of "street heroin" with fentanyl, poses great danger for acute health complications, including a comatose state and death.

Provision of magnetic resonance imaging for patients with 'MR-conditional' cardiac implantable electronic devices: an unmet clinical need.

Increasing need for magnetic resonance imaging (MRI) has driven the development of MR-conditional cardiac implantable electronic devices (CIEDs; pacemakers and defibrillators); however, patients still report difficulties obtaining scans. We sought to establish current provision for MRI scanning of patients with CIEDs in England. A survey was distributed to all hospitals in England with MRI, to assess current practice. Information requested included whether hospitals currently offer MRI to this patient group, the number and type of scans acquired, local safety considerations, complications experienced and perceived obstacles to service provision in those departments not currently offering it. Responses were received from 195 of 227 (86%) of hospitals surveyed. Although 98% of departments were aware of MR-conditional devices, only 46% (n = 89) currently offer MRI scans to patients with CIED's; of these, 85% of departments perform ≤10 scans per year. No major complications were reported from MRI scanning in patients with MR-conditional devices. Current barriers to service expansion include perceived concerns regarding potential risk, lack of training, logistical difficulties, and lack of cardiology support. Provision of MRI for patients with CIEDs is currently poor, despite increasing numbers of patients with MR-conditional devices and extremely low reported complication rates.

2014-07-01

While transcatheter aortic valve replacement( TAVR) has spread rapidly all over the world for highrisk patients with severe aortic stenosis (AS), SAPIEN XT was approved in Japan in October 2013. Since that, approximately 400 TAVR cases were performed in Japan. In our institute, we have performed 164 cases since first case in Japan in 2009 and have achieved satisfactory early results(30-day mortality:1.2%). At the same time, however, simultaneously various TAVR-related complications including a paravalvular leak, stroke, vascular complications, and coronary obstruction were observed. A reduction in the incidence and severity of these complications had led technical improvements in various new devices(2nd generation TAVR device such as the SAPIEN 3, ACURATE, and JenaValve) and in implantation techniques including repositioning/recapturing features, paravalvular sealing technologies, and prevention of coronary obstruction. Furthermore, there is also increasing experience with special indications for TAVR such as pure aortic valve insufficiency or valve-in-valve techniques. Currently, an increasing number of publications of midterm results demonstrate good prosthetic valve function and durability, with good quality of life and low morbidity after TAVR. There are also some randomized trials such as PARTNER 2 or SURTAVI to investigate potential benefits of TAVR for intermediate-risk patients. These improvements in the TAVR devices promises the expansion of TAVR towards the treatment of lower-risk patients in the near future.

Newcomers in paediatric GI pathology: childhood enteropathies including very early onset monogenic IBD.

2018-01-01

Childhood enteropathies are a group of diseases causing severe chronic (>2-3 weeks) diarrhoea often starting in the first week of life with the potential for fatal complications for the affected infant. Early identification and accurate classification of childhood enteropathies are, therefore, crucial for making treatment decisions to prevent life-threatening complications. Childhood enteropathies are classified into four groups based on the underlying pathology: (i) conditions related to defective digestion, absorption and transport of nutrients and electrolytes; (ii) disorders related to enterocyte differentiation and polarization; (iii) defects of enteroendocrine cell differentiation; and (iv) disorders associated with defective modulation of intestinal immune response. While the intestinal mucosa is usually normal in enteropathies related to congenital transport or enzyme deficiencies, the intestinal biopsy in other disorders may reveal a wide range of abnormalities varying from normal villous architecture to villous atrophy and/or inflammation, or features specific to the underlying disorder including epithelial abnormalities, lipid vacuolization in the enterocytes, absence of plasma cells, lymphangiectasia, microorganisms, and mucosal eosinophilic or histiocytic infiltration. This review intends to provide an update on small intestinal biopsy findings in childhood enteropathies, the "newcomers", including very early onset monogenic inflammatory bowel disease (IBD), in particular, for the practicing pathologist.

The purpose of this study is to determine the laser related complication rate for shoulder arthroscopy in the initial clinical experience of 50 patients, and to identify potential advantages of laser use in shoulder arthroscopy. Fifty patients spanning ages 25 to 87 were treated. Surgical debridement was selective and conservative creating a smooth post resection rim. In those that included rotator cuff tears, in addition to arthroscopic debridement, a mini arthrotomy and open acromioplasty were performed. Changes in arthroscopic technique due to laser use included no arthroscopic pump use and use of the shaver only when the fiber could not be easily seen with severe synovitis. We found that the hyper-vascular synovium did not need to be resected last, it could be resected at any point during the procedure. Four hundred and 600 micron fiberoptics were used as well as 20 watts average power. Technical advantage of the laser was felt to be the size of the instrument probe and the availability of excellent hemostasis. Complications include one case of arthroscope damage and one case with a broken fiber tip which was removed with a grasper. Long term follow up of these patients is now underway.

Diabetic foot is one of the most common complications of diabetes. It has the potential risk of pathologic consequences including infection, ulceration and amputation, but a growing body of evidence suggests that physical activity and exercise may improve diabetic foot outcomes. To analyze de effects of exercise and physical activity interventions on diabetic foot outcomes. A comprehensive and systematic search was conducted according to PRISMA recommendations. Only controlled clinical trials with patients with diabetes were included. Six studies, involving 418 patients with diabetes, were included. Two studies used only aerobic exercise; two studies combined aerobic, resistance and balance exercise; and two studies combined aerobic and balance exercise by Thai Chin Chuan methods. Physical activity and exercise significantly improved nerve velocity conduction, peripheral sensory function and foot peak pressure distribution. Moreover, the ulcers incidence rate per year was lower in the intervention groups, compared with the controls [0.02 vs. 0.12]. This review suggests evidence that physical activity and exercise is an effective non-pharmacological intervention to improve diabetic foot related outcomes. Combined multi-disciplinary treatments are more effective in the prevention of foot complications in patients with diabetes. Copyright © 2018 Elsevier B.V. All rights reserved.

Patent foramen ovale (PFO)-related stroke is increasingly recognized as an important etiology of ischemic embolic stroke-accounting for up to 50% of strokes previously considered 'cryptogenic' or with an unknown mechanism. As a 'back door to the brain,' PFO can allow venous clots to enter arterial circulation via interatrial right-to-left shunting, potentially resulting in ischemic stroke. We observe that clinically, PFO-related stroke affects women of childbearing age, and that pregnancy-owing to major changes in hemocoagulative, hormonal, and cardiovascular parameters-can enhance stroke risks. However, no systematic study has been performed and little is known regarding complications, pregnancy outcomes and treatment for PFO-related stroke during pregnancy. To identify and characterize the complications and clinical outcomes related to PFOs during pregnancy, we performed a literature review and analysis from all reported cases of pregnancy with PFO-related complications in the medical literature from 1970 to 2015. We find that during pregnancy and post-partum, PFO is associated with complications affecting multiple organs, including the brain, heart and lung. The three principal complications reported are stroke, pulmonary emboli and myocardial infarction. In contrast to other pregnancy-related stroke etiologies, which peak during later pregnancy and postpartum, PFO-related stroke peaks during early pregnancy (first and second trimester-60%), and most patients had good neurological outcome (77%). In patients with PFO with recurrent stroke during pregnancy, additional key factors include high-risk PFO morphology (atrial septal aneurysm), larger right-to-left shunt, multiple gestation and concurrent hypercoagulability. Compared to strokes of other etiologies during pregnancy, most PFO stroke patients experienced uneventful delivery (93%) of healthy babies with a good clinical outcome. We conclude with recommended clinical treatment strategies for pregnant patients with PFO suggested by the data from these cases, and the clinical experience of our Cardio-Neurology Clinic.

Background: During Ramadan, Muslims fast from dawn until dusk for one lunar month every year. Most of the Muslim patients with diabetes are unaware of the potential complications that can occur while fasting, such as hypoglycemia. The aim of this study is to assess the the patient education level and patients’ overall awareness of any possible complications that could occur while fasting during Ramadan and to determine how these patients deal with these complications. Methods: We conducted a cross-sectional study and surveyed diabetic patients about their diabetes-related knowledge over a period of 4 months from the outpatient clinic at the Obesity, Endocrine, and Metabolism Center at King Fahad Medical City. Patients were included if they were ≥16 years and if they had been receiving treatment for at least 1 year before the study, irrespective of the medications used; patients were also asked about the presence or absence of complications. Results: This study included 477 patients (325 women and 152 men). Most patients (297; 62.3%) had type 2 diabetes. The patients’ mean age was 39.72 ± 15.29 years, and the mean duration of diabetes was 10.80 ± 5.88 years. During the preceding Ramadan, 76% of patients reported fasting, whereas 58% said that they monitored their blood glucose levels once per day. Hypoglycemic episodes were reported in 60.3% of cases with type 2 diabetes and in 8.3% of cases with type 1 diabetes. Among those who had hypoglycemia, 2.8% of patients with type 1 diabetes and 17.8% with type 2 diabetes broke their fast. Finally, 54% of patients reported that their health care providers offered them instructions on diabetes management during Ramadan. Conclusions: Ramadan health education in diabetes can encourage, improve, and guide patients to change their lifestyles during Ramadan while minimizing the risk of acute complications. PMID:29348712

In the United States, 37.5 % of adults (78 million) are obese. The direct medical costs of treating obesity-related disease account for more than 6 % of the national health expenditure. Robotic bariatric surgery is becoming more common, but it is unclear whether robotic procedures result in lower complication rates. Additionally, some evidence is conflicting regarding the costs of robotic Roux-en-Y gastric bypass (RYGB) compared with those of laparoscopic RYGB. This study aimed to compare complication rates, operative characteristics, and expected costs between robotic and laparoscopic RYGB. A systematic review of the literature was performed with searches of five databases and grey literature, hand searches, and reference and forward citation searches. Studies comparing robotic versus laparoscopic RYGB involving patients ages 18-65 years who met the National Institutes of Health (NIH) criteria for bariatric surgery were included in the study if they reported overall or major complication rates. Outcomes were pooled using random-effects metaanalysis. A decision-tree economic analysis was performed to calculate expected costs associated with each technique. The systematic search strategy returned 1,374 potentially relevant studies. The inclusion criteria were met by 10 of these studies, which included results from 2,557 patients. The overall major and minor complications did not differ significantly between the robotic and laparoscopic groups. The rates for anastomotic leak, bleeding, stricture, and reoperation did not differ significantly. An economic analysis found that the expected costs for robotic RYGB ($15,447) were higher than for laparoscopic RYGB ($11,956). Sensitivity analyses produced similar results. The complication rates did not differ significantly between robotic and laparoscopic RYGB, but the expected costs were greater for robotic RYGB. Further cost effectiveness analyses are recommended before adoption of a robotic approach to RYGB.

Artioli, Guilherme Giannini; Sale, Craig; Jones, Rebecca Louise

2018-03-04

Carnosine was originally discovered in skeletal muscle, where it exists in larger amounts than in other tissues. The majority of research into the physiological roles of carnosine have been conducted on skeletal muscle. Given this and the potential for muscle carnosine content to be increased with supplementation, there is now a large body of research examining the ergogenic effects (or otherwise) of carnosine. More recent research, however, points towards a potential for carnosine to exert a wider range of physiological effects in other tissues, including the brain, heart, pancreas, kidney and cancer cells. Taken together, this is suggestive of a potential for carnosine to have therapeutic benefits in health and disease, although this is by no means without complication. Herein, we will provide a review of the current literature relating to the potential therapeutic effects of carnosine in health and disease.

Your brain on drugs: imaging of drug-related changes in the central nervous system.

Drug abuse is a substantial problem in society today and is associated with significant morbidity and mortality. Various drugs are associated with serious complications affecting the brain, and it is critical to recognize the imaging findings of these complications to provide prompt medical management. The central nervous system (CNS) is a target organ for drugs of abuse as well as specific prescribed medications. Drugs of abuse affecting the CNS include cocaine, heroin, alcohol, amphetamines, toluene, and cannabis. Prescribed medications or medical therapies that can affect the CNS include immunosuppressants, antiepileptics, nitrous oxide, and total parenteral nutrition. The CNS complications of these drugs include neurovascular complications, encephalopathy, atrophy, infection, changes in the corpus callosum, and other miscellaneous changes. Imaging abnormalities indicative of these complications can be appreciated at both magnetic resonance (MR) imaging and computed tomography (CT). It is critical for radiologists to recognize complications related to drugs of abuse as well as iatrogenic effects of various medications. Therefore, diagnostic imaging modalities such as MR imaging and CT can play a pivotal role in the recognition and timely management of drug-related complications in the CNS.

Surgical patient selection and counseling.

The objectives of patient selection and counseling are ultimately to enhance successful outcomes. However, the definition for success is often narrowly defined in published literature (ability to complete surgery, complications, satisfaction) and fails to account for patient desires and expectations, temporal changes, natural history of underlying diseases, or independent validation. Factors associated with satisfaction and dissatisfaction are often surgery-specific, although correlation with pre-operative expectations, revisions, and complications are common with most procedures. The process of appropriate patient selection is determined by the integration of patient and surgeon factors, including psychological capacity to handle unsatisfactory results, baseline expectations, complexity of case, and surgeon volume and experience. Using this model, a high-risk scenario includes one in which a low-volume surgeon performs a complex case in a patient with limited psychological capacity and high expectations. In contrast, a high-volume surgeon performing a routine case in a male with low expectations and abundant psychiatric reserve is more likely to achieve a successful outcome. To further help identify patients who are at high risk for dissatisfaction, a previously published mnemonic is recommended: CURSED Patient (compulsive/obsessive, unrealistic, revision, surgeon shopping, entitled, denial, and psychiatric). Appropriate patient counseling includes setting appropriate expectations, reviewing the potential and anticipated risks of surgery, post-operative instruction to limit complications, and long-term follow-up. As thorough counseling is often a time-consuming endeavor, busy practices may elect to utilize various resources including educational materials, advanced practice providers, or group visits, among others. The consequences for poor patient selection and counseling may range from poor surgical outcomes and patient dissatisfaction to lawsuits, loss of credibility, or even significant patient or personal harm.

Dramatic increases in the average life expectancy have led to increases in the variety of degenerative changes and deformities observed in the aging spine. The elderly population can present challenges for spine surgeons, not only because of increased comorbidities, but also because of the quality of their bones. Pedicle screws are the implants used most commonly in spinal surgery for fixation, but their efficacy depends directly on bone quality. Although polymethyl methacrylate (PMMA)-augmented screws represent an alternative for patients with osteoporotic vertebrae, their use has raised some concerns because of the possible association between cement leakages (CLs) and other morbidities. To analyze potential complications related to the use of cement-augmented screws for spinal fusion and to investigate the effectiveness of using these screws in the treatment of patients with low bone quality. A retrospective single-center study. This study included 313 consecutive patients who underwent spinal fusion using a total of 1,780 cement-augmented screws. We analyzed potential complications related to the use of cement-augmented screws, including CL, vascular injury, infection, screw extraction problems, revision surgery, and instrument failure. There are no financial conflicts of interest to report. A total of 1,043 vertebrae were instrumented. Cement leakage was observed in 650 vertebrae (62.3%). There were no major clinical complications related to CL, but two patients (0.6%) had radicular pain related to CL at the S1 foramina. Of the 13 patients (4.1%) who developed deep infections requiring surgical debridement, two with chronic infections had possible spondylitis that required instrument removal. All patients responded well to antibiotic therapy. Revision surgery was performed in 56 patients (17.9%), most of whom had long construction. A total of 180 screws were removed as a result of revision. There were no problems with screw extraction. These results demonstrate the efficacy and safety of cement-augmented screws for the treatment of patients with low bone mineral density. Copyright © 2017 Elsevier Inc. All rights reserved.

Decision making regarding Smith-Petersen vs. pedicle subtraction osteotomy vs. vertebral column resection for spinal deformity.

Author experience and literature review. To investigate and discuss decision-making on when to perform a Smith-Petersen osteotomy as opposed to a pedicle subtraction procedure and/or a vertebral column resection. Articles have been published regarding Smith-Petersen osteotomies, pedicle subtraction procedures, and vertebral column resections. Expectations and complications have been reviewed. However, decision-making regarding which of the 3 procedures is most useful for a particular spinal deformity case is not clearly investigated. Discussed in this manuscript is the author's experience and the literature regarding the operative options for a fixed coronal or sagittal deformity. There are roles for Smith-Petersen osteotomy, pedicle subtraction, and vertebral column resection. Each has specific applications and potential complications. As the magnitude of resection increases, the ability to correct deformity improves, but also the risk of complication increases. Therein, an understanding of potential applications and complications is helpful.

Osteomyelitis is an inflammation of the bone caused by an infection. Though bone is normally resistant to bacterial infection, events including trauma, presence of foreign bodies including prosthesis can act as a nidus for infection. Osteomyelitis is a rare but recognised complication of radiotherapy. Osteomyelitis of the pubis has scarcely been reported as a complication following urological procedures- prostatectomy, sling surgery and catheterisation. We report a rare complication of a gentleman post radiotherapy presenting with delayed osteomyelitis of the pubis following supra-pubic catheterisation.

The Hospital Acquired Condition Strategy (HACS) denies payment for venous thromboembolism (VTE) after total knee arthroplasty (TKA). The intention is to reduce complications and associated costs, while improving the quality of care by mandating VTE prophylaxis. We applied a system dynamics model to estimate the impact of HACS on VTE rates, and potential unintended consequences such as increased rates of bleeding and infection and decreased access for patients who might benefit from TKA. The system dynamics model uses a series of patient stocks including the number needing TKA, deemed ineligible, receiving TKA, and harmed due to surgical complication. The flow of patients between stocks is determined by a series of causal elements such as rates of exclusion, surgery and complications. The number of patients harmed due to VTE, bleeding or exclusion were modeled by year by comparing patient stocks that results in scenarios with and without HACS. The percentage of TKA patients experiencing VTE decreased approximately 3-fold with HACS. This decrease in VTE was offset by an increased rate of bleeding and infection. Moreover, results from the model suggest HACS could exclude 1.5% or half a million patients who might benefit from knee replacement through 2020. System dynamics modeling indicates HACS will have the intended consequence of reducing VTE rates. However, an unintended consequence of the policy might be increased potential harm resulting from over administration of prophylaxis, as well as exclusion of a large population of patients who might benefit from TKA.

Critical care considerations in the management of the trauma patient following initial resuscitation

PubMed Central

2012-01-01

Background Care of the polytrauma patient does not end in the operating room or resuscitation bay. The patient presenting to the intensive care unit following initial resuscitation and damage control surgery may be far from stable with ongoing hemorrhage, resuscitation needs, and injuries still requiring definitive repair. The intensive care physician must understand the respiratory, cardiovascular, metabolic, and immunologic consequences of trauma resuscitation and massive transfusion in order to evaluate and adjust the ongoing resuscitative needs of the patient and address potential complications. In this review, we address ongoing resuscitation in the intensive care unit along with potential complications in the trauma patient after initial resuscitation. Complications such as abdominal compartment syndrome, transfusion related patterns of acute lung injury and metabolic consequences subsequent to post-trauma resuscitation are presented. Methods A non-systematic literature search was conducted using PubMed and the Cochrane Database of Systematic Reviews up to May 2012. Results and conclusion Polytrauma patients with severe shock from hemorrhage and massive tissue injury present major challenges for management and resuscitation in the intensive care setting. Many of the current recommendations for “damage control resuscitation” including the use of fixed ratios in the treatment of trauma induced coagulopathy remain controversial. A lack of large, randomized, controlled trials leaves most recommendations at the level of consensus, expert opinion. Ongoing trials and improvements in monitoring and resuscitation technologies will further influence how we manage these complex and challenging patients. PMID:22989116

Abdominal aortic aneurysms: pre- and post-procedural imaging.

PubMed

Hallett, Richard L; Ullery, Brant W; Fleischmann, Dominik

2018-05-01

Abdominal aortic aneurysm (AAA) is a relatively common, potentially life-threatening disorder. Rupture of AAA is potentially catastrophic with high mortality. Intervention for AAA is indicated when the aneurysm reaches 5.0-5.5 cm or more, when symptomatic, or when increasing in size > 10 mm/year. AAA can be accurately assessed by cross-sectional imaging including computed tomography angiography and magnetic resonance angiography. Current options for intervention in AAA patients include open surgery and endovascular aneurysm repair (EVAR), with EVAR becoming more prevalent over time. Cross-sectional imaging plays a crucial role in AAA surveillance, pre-procedural assessment, and post-EVAR management. This paper will discuss the current role of imaging in the assessment of AAA patients prior to intervention, in evaluation of procedural complications, and in long-term follow-up of EVAR patients.

Cardiovascular and systemic effects of gastric dilatation and volvulus in dogs.

PubMed

Sharp, Claire R; Rozanski, Elizabeth A

2014-09-01

Gastric dilatation and volvulus (GDV) is a common emergency condition in large and giant breed dogs that is associated with high morbidity and mortality. Dogs with GDV classically fulfill the criteria for the systemic inflammatory response syndrome (SIRS) and can go on to develop multiple organ dysfunction syndrome (MODS). Previously reported organ dysfunctions in dogs with GDV include cardiovascular, respiratory, gastrointestinal, coagulation and renal dysfunction. Cardiovascular manifestations of GDV include shock, cardiac arrhythmias and myocardial dysfunction. Respiratory dysfunction is also multifactorial, with contributory factors including decreased respiratory excursion due to gastric dilatation, decreased pulmonary perfusion and aspiration pneumonia. Gastrointestinal dysfunction includes gastric necrosis and post-operative gastrointestinal upset such as regurgitation, vomiting, and ileus. Coagulation dysfunction is another common feature of MODS in dogs with GDV. Disseminated intravascular coagulation can occur, putting them at risk of complications associated with thrombosis in the early hypercoagulable state and hemorrhage in the subsequent hypocoagulable state. Acute kidney injury, acid-base and electrolyte disturbances are also reported in dogs with GDV. Understanding the potential for systemic effects of GDV allows the clinician to monitor patients astutely and detect such complications early, facilitating early intervention to maximize the chance of successful management.

CT-guided transthoracic core-needle biopsy (TTNB) is frequently used for the diagnosis of lung nodules. The aim of this study is to describe TTNBs' complications and to investigate predictive factors of complications. All consecutive TTNBs performed in three centers between 2006 and 2012 were included. Binary logistic regression was used for multivariate analysis. Overall, 970 TTNBs were performed in 929 patients. The complication rate was 34% (life-threatening complication in 6%). The most frequent complications were pneumothorax (29% included 4% which required chest-tube) and hemoptysis (5%). The mortality rate was 0.1% (n=1). In multivariate analysis, predictive factor for a complication was small target size (AOR=0.984; 95% CI [0.976-0.992]; P<0.001). This predictive factor was also found for occurrence of life-threatening complication (AOR=0.982; [0.965-0.999]; P=0.037), of pneumothorax (AOR=0.987; [0.978-0.995]; P=0.002) and of hemoptysis (AOR=0.973; [0.951-0.997]; P=0.024). One complication occurred in one-third of TTNBs. The proportion of life-threatening complication was 6%. A small lesion size was predictive of complication occurrence.

First-time donation is among recognised risk factors for vasovagal reactions to blood donation and reactions are known to reduce donor return. We assessed associations between potential risk factors and vasovagal reactions and needle-related complications in first-time whole blood donation in comparison to repeat donation and analysed the impact of complications on donor return. We performed a cohort study on whole blood donations in The Netherlands from 1/1/2010 to 31/12/2010 using data extracted from the blood service information system. Donation data up to 31/12/2011 were used to ascertain donor return. In 2010 28,786 donors made first whole blood donations and there were 522,958 repeat donations. Vasovagal reactions occurred in 3.9% of first donations by males and 3.5% of first donations by females compared to in 0.2% and 0.6%, respectively, of repeat donations. Associations of vasovagal reactions with other factors including age, body weight, systolic and diastolic blood pressure were similar in first-time and repeat donors. Needle-related complications occurred in 0.2% of male and 0.5% of female first-time donations and in 0.1% and 0.3%, respectively, of repeat donations. Among first-time donors, the return rate within 1 year was 82% following an uncomplicated first donation, but 55% and 61% following vasovagal reactions and needle-related complications, respectively; the corresponding percentages among repeat donors were 86%, 58% and 82%. Among first-time donors, females suffered less than males from vasovagal reactions. Other risk factors had similar associations among first-time and repeat donors. Vasovagal reactions and needle-related complications in both first-time and repeat donors are followed by reduced donor return.

Neurologic injury associated with regional anesthetic or pain medicine procedures is extremely rare. The Second American Society of Regional Anesthesia and Pain Medicine Practice Advisory on Neurologic Complications Associated With Regional Anesthesia and Pain Medicine focuses on those complications associated with mechanical, ischemic, or neurotoxic injury of the neuraxis or peripheral nervous system. As with the first advisory, this iteration does not focus on hemorrhagic or infectious complications or local anesthetic systemic toxicity, all of which are the subjects of separate practice advisories. The current advisory offers recommendations to aid in the understanding and potential limitation of rare neurologic complications that may arise during the practice of regional anesthesia and/or interventional pain medicine. The Second American Society of Regional Anesthesia and Pain Medicine Practice Advisory on Neurologic Complications Associated With Regional Anesthesia and Pain Medicine updates information that was originally presented at the Society's first open forum on this subject (2005) and published in 2008. Portions of the second advisory were presented in an open forum (2012) and are herein updated, with attention to those topics subject to evolving knowledge since the first and second advisory conferences. The second advisory briefly summarizes recommendations that have not changed substantially. New to this iteration of the advisory is information related to the risk of nerve injury inherent to common orthopedic surgical procedures. Recommendations are expanded regarding the preventive role of various monitoring technologies such as ultrasound guidance and injection pressure monitoring. New clinical recommendations focus on emerging concerns including spinal stenosis and vertebral canal pathologies, blood pressure management during neuraxial anesthesia, administering blocks in anesthetized or deeply sedated patients, patients with preexisting neurologic disease, and inflammatory neuropathies. An updated diagnostic and treatment algorithm is presented.

Image-based and imageless computer-assisted total knee arthroplasty (CATKA) has become increasingly popular. This study aims to compare outcomes, including perioperative complications and transfusion rate, between CATKA and conventional total knee arthroplasty (TKA), as well as between image-based and imageless CATKA. Using the 9th revision of the International Classification of Diseases codes, we queried the Nationwide Inpatient Sample database from 2005 to 2011 to identify unilateral conventional TKA, image-based, and imageless CATKAs as well as in-hospital complications and transfusion rates. A total of 787,809 conventional TKAs and 13,246 CATKAs (1055 image-based and 12,191 imageless) were identified. The rate of CATKA increased 23.13% per year from 2005 to 2011. Transfusion rates in conventional TKA and CATKA cases were 11.73% and 8.20% respectively (P < .001) and 6.92% in image-based vs 8.27% in imageless (P = .023). Perioperative complications occurred in 4.50%, 3.47%, and 3.41% of cases after conventional, imageless, and imaged-based CATKAs, respectively. Using multivariate analysis, perioperative complications were significantly higher in conventional TKA compared to CATKA (odds ratio = 1.17, 95% confidence interval 1.03-1.33, P = .01). There was no significant difference between imageless and image-based CATKA (P = .34). Length of hospital stay and hospital charges were not significantly different between groups (P > .05). CATKA has low complication rates and may improve patient outcomes after TKA. CATKA, especially the image-based technique, may reduce in-hospital complications and transfusion without increasing hospital charges and length of hospital stay significantly. Large prospective studies with long follow-up are required to verify potential benefits of CATKA. Copyright © 2017 Elsevier Inc. All rights reserved.

Intra-arterial chemotherapy (IAC) for retinoblastoma has been documented as causing visual loss and ocular motility problems. A lack of safety data has precluded its acceptance in all centres. Retrospective cohort study of patients with retinoblastoma from 2013 to 2015 who had a healthy foveola and relapsed following systemic chemotherapy. All required IAC. The correlation of complications with doses of melphalan +/- topotecan used and putative catheterisation complications was assessed. Ocular complications were determined using vision, macular (including pattern visual evoked potentials (PVEPs)), retinal electroretinograms (ERGs) and ocular motility functions. Efficacy (tumour control) was also assessed. All eyes had age appropriate doses of melphalan with five having additional doses of topotecan. Severe physiological reactions requiring adrenaline were seen in six patients during the catheterisation procedure. Difficulty was documented in accessing the ophthalmic artery in 7/27 catheterisations. The median/mean number of courses of chemotherapy was three. No child had severe visual loss as assessed by age appropriate tests (median follow-up 20.9 months, range 3.7-35.2 months). One child had nasal choroidal ischaemia and a sixth nerve palsy. Post-IAC PVEPs were performed in eight and reported as normal. All post-IAC ERGs were normal apart from one (total dose 20 mg melphalan 0.8 mg topotecan). Tumour control was achieved in six of nine cases. The proportion of visual and ocular motility complications may be reduced by providing age-adjusted doses of melphalan. Dose rather than complications from catheterisation is the most important risk factor for ocular injury. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Objective To investigate the effects of nasal continuous positive airway pressure (CPAP) and cannula use in the neonatal intensive care unit. Design Cross-sectional study. Setting Tertiary care children’s hospital. Patients One hundred patients (200 nasal cavities), younger than 1 year, who received at least 7 days of nasal CPAP (n = 91) or cannula supplementation (n = 9) in the neonatal intensive care unit. Interventions External nasal examination and anterior nasal endoscopy with photographic documentation. Main Outcome Measures The incidence and characteristics of internal and external nasal findings of patients with nasal CPAP or cannula use. Results Nasal complications were seen in 12 of the 91 patients (13.2%) with at least 7 days of nasal CPAP exposure, while no complications were seen in the 9 patients with nasal cannula use alone. The external nasal finding of columellar necrosis, seen in 5 patients (5.5%), occurred as early as 10 days after nasal CPAP use. Incidence of intranasal findings attributed to CPAP use, in the 182 nostrils examined, included ulceration in 6 nasal cavities (3.3%), granulation in 3 nasal cavities (1.6%), and vestibular stenosis in 4 nasal cavities (2.2%). Intranasal complications were seen as early as 8 to 9 days after nasal CPAP administration. Nasal complications from CPAP were associated with lower Apgar scores at 1 (P = .02) and 5 (P = .06) minutes. Conclusions External or internal complications of nasal CPAP can be relatively frequent (13.2%) and can occur early, and patients with lower Apgar scores may be at higher risk. Close surveillance for potential complications should be considered during nasal CPAP use. PMID:20231649

The use of human acellular dermal matrices (ADM) has become routinely used in implant-based breast surgery. Notwithstanding the many benefits for tissue support, the morbidity associated with its use includes seroma and infection, among other potential complications. Some patients experience a specific complication called red breast syndrome (RBS), which has been linked to ADM use, but its exact etiology remains elusive. In our institution, AlloDerm aseptic regenerative tissue matrix was recently replaced with a ready-to-use sterile version that undergoes terminal sterilization, eliminating the need for rehydration. We want to determine if this change in processing affected complications, including RBS. We conducted a retrospective chart review analyzing patients from January 1, 2011, to June 1, 2013, who underwent breast surgery with human ADM. Patients with aseptic AlloDerm were compared to patients with sterile AlloDerm. Data were analyzed using the Fisher exact test. A total of 167 reconstructed breasts from 105 patients met inclusion criteria: 56% (n=93) with aseptic ADM, 44% (n=74) with sterile ADM. When comparing the two, patients had a decrease in overall necrosis, infection, seroma, and RBS with sterile ADM. However, the rates did not reach statistical significance. For example, the incidence of RBS decreased from 7.5% to 2.7% (P=0.301) and seroma decreased from 8.6% to 2.7% (P=0.188). The infection rate proved to be equivocal at 11.8% with aseptic ADM to 10.8% with sterile ADM (P=1.000). The only statistically significant change was a decrease in the total complication rate from 41.9% to 27.0% (P=0.046). The absolute risk reduction for total complications was 14.9% with a number-needed-to-treat of 7. According to our study, sterile AlloDerm has a clinically decreased incidence of complications compared to aseptic AlloDerm. Whereas RBS decreased, it was interesting to see that it was not eliminated altogether. This suggests that the etiology may be unrelated to ADM processing and warrants further investigation. Overall, the most notable difference was the statistically significant decrease in the total complication rate. Therefore, the change to sterile AlloDerm seems to be beneficial. Further benefit arises from ease of preparation in the operating room.

2017-01-01

Background Venous thromboembolism (VTE) is a relatively common and potentially life threatening complication after major hip surgery. There are two main types of prophylaxis: chemical and mechanical. Chemical prophylaxis is very effective but causes bleeding complications in surgical wounds and remote organs. On the other hand, mechanical methods are free of hemorrhagic complications but are less effective. We hypothesized that mechanical prophylaxis is effective enough for Asians in whom VTE occurs less frequently. This study evaluated the effect of intermittent pneumatic compression (IPC) in the prevention of VTE after major hip surgery. Methods Incidences of symptomatic VTE after primary total hip arthroplasty with and without application of IPC were compared. A total of 379 patients were included in the final analysis. The IPC group included 233 patients (106 men and 127 women) with a mean age of 54 years. The control group included 146 patients (80 men and 66 women) with a mean age of 53 years. All patients took low-dose aspirin for 6 weeks after surgery. IPC was applied to both legs just after surgery and maintained all day until discharge. When a symptom or a sign suspicious of VTE, such as swelling or redness of the foot and ankle, Homans' sign, and dyspnea was detected, computed tomography (CT) angiogram or duplex ultrasonogram was performed. Results Until 3 months after surgery, symptomatic VTE occurred in three patients in the IPC group and in 6 patients in the control group. The incidence of VTE was much lower in the IPC group (1.3%) than in the control group (4.1%), but the difference was not statistically significant. Complications associated with the application of IPC were not detected in any patient. Patients affected by VTE were older and hospitalized longer than the unaffected patients. Conclusions The results of this study suggest that IPC might be an effective and safe method for the prevention of postoperative VTE. PMID:28261425

Challenges in diabetes management in Indonesia: a literature review

2013-01-01

Background and objectives The expanding diabetes epidemic worldwide could have potentially devastating effects on the development of healthcare systems and economies in emerging countries, both in terms of direct health care costs and loss of working time and disability. This study aims to review evidence on the burden, expenditure, complications, treatment, and outcomes of diabetes in Indonesia and its implications on the current health system developments. Methods We conducted a comprehensive literature review together with a review of unpublished data from the Ministry of Health and a public health insurer (Askes). Studies presenting evidence on prevalence, incidence, mortality, costs, complications and cost of complications, treatment, and outcomes were included in the analysis. Results A limited number of international, national and local studies on the burden and cost of diabetes in Indonesia were identified. National survey data suggests that in 2007 the prevalence of diabetes was 5.7%, of which more than 70% of cases were undiagnosed. This estimate hides large intracountry variation. There was very limited data available on direct costs and no data on indirect costs. The most commonly-identified complication was diabetic neuropathy. Discussion There were a number of limitations in the data retrieved including the paucity of data representative at the national level, lack of a clear reference date, lack of data from primary care, and lack of data from certain regions of the country. Conclusions If left unaddressed, the growing prevalence of diabetes in the country will pose a tremendous challenge to the Indonesian healthcare system, particularly in view of the Government’s 2010 mandate to achieve universal health coverage by 2014. Essential steps to address this issue would include: placing diabetes and non-communicable diseases high on the Government agenda and creating a national plan; identifying disparities and priority areas for Indonesia; developing a framework for coordinated actions between all relevant stakeholders.

Gallstone disease is common. However, a proportion of patients are asymptomatic and remain undiagnosed until the occurrence of complications. Common complications include acute cholecystitis, biliary obstruction, acute pancreatitis and cholangitis. Severe complications include gallbladder perforation, Mirizzi syndrome and fistula formation are usually associated with significant morbidity and mortality. We report a case of asymptomatic spotaneous gallbladder perforation due to acute cholecystitis. PMID:24914424

Devastating tornados struck the state of Kansas on Friday, April 26, 1991. Twenty lives were lost and many people were injured. Property damage was extensive. Overall, the outcome of those admitted to the various hospitals was good, with few orthopedic-related complications. The low complication rate can be attributed to thorough open wound management and suspicion and recognition of other potential orthopedic complications such as compartment syndrome.

The potential for adverse events with lasting functional effects makes cranial nerve (CN) injury a target for litigation. Our objective was to comprehensively examine records of malpractice trials and detail issues influencing outcomes. Retrospective analysis. The Westlaw database (Thomson Reuters, New York, NY) was searched for jury verdict reports related to medical malpractice and CN injury. After excluding nonrelevant cases, we examined 209 trials for characteristics including nerve(s) injured, alleged causes of malpractice, demographic information, specialty, and outcome. The most commonly litigated CNs were VII (24.4%) and II (19.6%). Sixty-nine (33.0%) trials resulted in damages awarded. Outcomes varied, ranging from a 29.2% plaintiff success rate for CN XI injury to 48.4% for CN II injury. Plaintiffs had less success with increasing age. Average damages awarded were $1.7 million. The most commonly named defendants were otolaryngologists and general surgeons. Individual considerations varied but commonly included alleged deficits in informed consent (25.4%), unnecessary procedures (14.8%), undergoing additional surgery (25.8%), and untimely recognition of complications (23.9%). Malpractice trials were resolved in the defendant's favor the majority of the time. In cases where plaintiffs were successful, however, awards were considerable, averaging nearly $2 million. Factors influencing case outcome included age, location, perceived deficits in informed consent, allegedly unnecessary surgery, requiring additional surgery to repair a complication, and untimely recognition of complications. Although specific factors should be taken into consideration with each procedure, providing detailed informed consent and communicating with patients regarding expectations may minimize liability.

Gastrostomy feeding in cerebral palsy: a systematic review

PubMed Central

Sleigh, G; Brocklehurst, P

2004-01-01

Aims: To determine benefits and risks for gastrostomy or jejunostomy feeding compared with oral feeding for children with cerebral palsy. Methods: Systematic review. Search strategy: electronic databases—Cochrane Library, Medline, Embase, Cinahl, Lilacs, databases of theses, grey literature. Included: relevant systematic reviews, randomised controlled trials, observational studies, case reports. Excluded: non-systematic reviews and qualitative research. Participants: children with cerebral palsy. Intervention: use of gastrostomy or jejunostomy tube to provide nutrition. Outcome: evaluated outcome measures included death, growth, gastro-oesophageal reflux, other complications, psychosocial aspects, and caregiver wellbeing. Results: No relevant systematic reviews or randomised controlled trials were found. Two cohort studies, 15 case series, and eight case reports met the inclusion criteria. Eight studies specifically described percutaneous endoscopic gastrostomy as the intervention. Weight gain resulted from gastrostomy feeding in most cases. There was an approximately fourfold increased risk of death reported in one cohort study for the gastrostomy fed children. Many complications were reported, including potential for increased gastro-oesophageal reflux and fluid aspiration into the lungs. Conclusions: Benefits associated with gastrostomy or jejunostomy feeding are difficult to assess from the available evidence. Risks of gastrostomy, particularly in relation to surgical complications, have been described but the size of the risk could not be quantified. The finding of a higher death rate for children fed by gastrostomy may merely reflect the greater disability of these compared with orally fed children. Lack of available evidence and the substantial risk of bias in observational studies suggests that a well conducted randomised controlled trial of sufficient size will be needed to answer these problems.

Background Surgical complications represent a significant cause of morbidity and mortality with the rate of major complications after inpatient surgery estimated at 3–17% in industrialised countries. The purpose of this review was to summarise experience with surgical checklist use and efficacy for improving patient safety. Methods A search of four databases (MEDLINE, CINAHL, EMBASE and the Cochrane Database of Controlled Trials) was conducted from 1 January 2000 to 26 October 2012. Articles describing actual use of the WHO checklist, the Surgical Patient Safety System (SURPASS) checklist, a wrong-site surgery checklist or an anaesthesia equipment checklist were eligible for inclusion (this manuscript summarises all but the anaesthesia equipment checklists, which are described in the Agency for Healthcare Research and Quality publication). Results We included a total of 33 studies. We report a variety of outcomes including avoidance of adverse events, facilitators and barriers to implementation. Checklists have been adopted in a wide variety of settings and represent a promising strategy for improving the culture of patient safety and perioperative care in a wide variety of settings. Surgical checklists were associated with increased detection of potential safety hazards, decreased surgical complications and improved communication among operating staff. Strategies for successful checklist implementation included enlisting institutional leaders as local champions, incorporating staff feedback for checklist adaptation and avoiding redundancies with existing systems for collecting information. Conclusions Surgical checklists represent a relatively simple and promising strategy for addressing surgical patient safety worldwide. Further studies are needed to evaluate to what degree checklists improve clinical outcomes and whether improvements may be more pronounced in particular settings. PMID:23922403

To describe the current data regarding effectiveness, complications, postoperative evaluation, and surgical interventions associated with Essure hysteroscopic sterilization. Hysteroscopic sterilization is a commonly performed procedure that is offered as a well tolerated, effective, outpatient method of permanent sterilization. Over the past several years, concerns have been raised regarding correct placement and postoperative complications. This has led to statements by both the Food and Drug Administration (FDA) in October, 2016 and American Association of Gynecologic Laparoscopists in February, 2017, as a significant portion of women seek removal of these devices. A current black-box warning issued by the FDA in 2016 recommends discussion of 'the probabilities of rates or events' of adverse outcomes associated with Essure placement. Although hysteroscopic sterilization is usually a safe, effective option for permanent contraception, new evidence regarding complications has emphasized the need for proper education and counseling. Appropriate patient selection and knowledge of potential complications is paramount to ensuring patients, and medical providers are well informed and have realistic expectations regarding potential placement and postoperative issues.

The Endocannabinoid System and Plant-Derived Cannabinoids in Diabetes and Diabetic Complications

Horváth, Béla; Mukhopadhyay, Partha; Haskó, György; Pacher, Pál

2012-01-01

Oxidative stress and inflammation play critical roles in the development of diabetes and its complications. Recent studies provided compelling evidence that the newly discovered lipid signaling system (ie, the endocannabinoid system) may significantly influence reactive oxygen species production, inflammation, and subsequent tissue injury, in addition to its well-known metabolic effects and functions. The modulation of the activity of this system holds tremendous therapeutic potential in a wide range of diseases, ranging from cancer, pain, neurodegenerative, and cardiovascular diseases to obesity and metabolic syndrome, diabetes, and diabetic complications. This review focuses on the role of the endocannabinoid system in primary diabetes and its effects on various diabetic complications, such as diabetic cardiovascular dysfunction, nephropathy, retinopathy, and neuropathy, particularly highlighting the mechanisms beyond the metabolic consequences of the activation of the endocannabinoid system. The therapeutic potential of targeting the endocannabinoid system and certain plant-derived cannabinoids, such as cannabidiol and Δ9-tetrahydrocannabivarin, which are devoid of psychotropic effects and possess potent anti-inflammatory and/or antioxidant properties, in diabetes and diabetic complications is also discussed.

This study identified the demographic profile, obstetric and clinical diagnoses, nursing diagnosis and most common collaboration problem among pregnant women subject to high-risk at a hospital in São Paulo, Brazil. Data were collected by means of a form based on Gordon's Functional Health Patterns. Nursing diagnoses were determined on the basis of the NANDA (North American Nursing Diagnosis Association) taxonomy. The nursing diagnoses found in 50% or more of the pregnant women were: risk for infection (90.1%), altered health maintenance (84.5%), altered comfort (80.3%), risk of ineffective breastfeeding (59.2%), altered sexuality patterns (52.1%), fear (52.1%) and pain (50.7%). The collaboration problem found in 50% or more of the cases was: potential complication: preterm labor (62.0%), potential complication: maternal tachycardia (54,9%) and potential complication: hypotension (54,9%). Thus, these results will allow us to guide the nursing care rendered to these pregnant women.

Diabetes mellitus is estimated to affect ∼24 million people in the United States and more than 150 million people worldwide. There are numerous end organ complications of diabetes, the onset of which can be delayed by early diagnosis and treatment. Although assays for diabetes are well founded, tests for its complications lack sufficient specificity and sensitivity to adequately guide these treatment options. In our study, we employed a streptozotocin-induced rat model of diabetes to determine changes in urinary protein profiles that occur during the initial response to the attendant hyperglycemia (e.g. the first two months) with the goal of developing a reliable and reproducible method of analyzing multiple urine samples as well as providing clues to early markers of disease progression. After filtration and buffer exchange, urinary proteins were digested with a specific protease, and the relative amounts of several thousand peptides were compared across rat urine samples representing various times after administration of drug or sham control. Extensive data analysis, including imputation of missing values and normalization of all data was followed by ANOVA analysis to discover peptides that were significantly changing as a function of time, treatment and interaction of the two variables. The data demonstrated significant differences in protein abundance in urine before observable pathophysiological changes occur in this animal model and as function of the measured variables. These included decreases in relative abundance of major urinary protein precursor and increases in pro-alpha collagen, the expression of which is known to be regulated by circulating levels of insulin and/or glucose. Peptides from these proteins represent potential biomarkers, which can be used to stage urogenital complications from diabetes. The expression changes of a pro-alpha 1 collagen peptide was also confirmed via selected reaction monitoring. PMID:19497846

Abdominal complications following cardiopulmonary bypass (CPB) procedures may have mortality rates as high as 25%. Advanced procedures such as ventricular assist devices, artificial hearts and cardiac transplantation are being increasingly employed, changing the complexity of interventions. This study was undertaken to examine the changing trends in complications and the impact of cardiac surgery on emergency general surgery (EGS) coverage. A retrospective review was conducted of all CPB procedures admitted to our ICU between Jan. 2007 and Mar. 2010. The procedures included coronary bypass (CABG), valve, combination (including adult congenital) and advanced heart failure (AHF) procedures. The records were reviewed to obtain demographics, need for EGS consult/procedure and outcomes. Mean age of the patients was 66 ± 8.5 years, 71% were male. There were 945 CPB procedures performed on 914 patients during this study period. Over 39 months, 23 EGS consults were obtained, resulting in 10 operations and one hospital death (10% operative mortality). CABG and valve procedures had minimal impact on EGS workload while complex cardiac and AHF procedures accounted for significantly more EGS consultations (p < 0.005) and operations (p < 0.005). The majority of consultations were for small bowel obstruction/ileus (n = 4, 17%), cholecystitis (n = 3, 13%) and to rule out ischemia (n = 2, 9%) In the era of modern critical care and cardiac surgery, advanced technology has increased the volume of complex CPB procedures increasing the EGS workload. Emergency general surgeons working in institutions that perform advanced procedures should be aware of the potential for general surgical complications perioperatively and the resultant nuances that are associated with operative management in this patient population.

This systematic review explored the indications, efficacy, and complications of hip arthroscopy in the setting of trauma. Databases (PubMed, Medline, Embase, and Web of Science) were searched from database inception to March 2015 for studies using hip arthroscopy in trauma treatment. Systematic screening of eligible studies was undertaken in duplicate. The inclusion criteria included studies pertaining to arthroscopic intervention of all traumatic hip injuries. Abstracted data were organized in table format with descriptive statistics presented. From an initial search yield of 2,809 studies, 32 studies (25 case reports and 7 case series) satisfied the criteria for inclusion. A total of 144 patients (age range, 10 to 53 years) underwent hip arthroscopy for 6 indications associated with trauma: 8 patients for bullet extraction, 6 for femoral head fixation, 82 for loose body removal, 6 for acetabular fracture fixation, 20 for labral intervention, and 23 for ligamentum teres debridement. Patients were followed up postoperatively for a mean of 2.9 years (range, 8 days to 16 years). Successful surgery was achieved in 96% of patients. The rate of major complications (i.e., pulmonary embolism and abdominal compartment syndrome) was 1.4% (2 of 144); avascular necrosis, 1.4% (2 of 144); and nerve palsy, 0.7% (1 of 144). Hip arthroscopy appears effective and safe in the setting of trauma. These data should be interpreted with caution because of the low-quality evidence of the included studies. Surgeons should be aware of the potential complications such as abdominal compartment syndrome and thromboembolic events when performing hip arthroscopy in the setting of trauma.

Infliximab was approved for use in ulcerative colitis in recent years. It has been debated if infliximab increases the risk of post-operative complications in patients with ulcerative colitis. To perform a meta-analysis that examines the relationship between preoperative infliximab treatment and short-term post-operative complications in patients with ulcerative colitis. We searched the PubMed and MEDLINE databases to identify observational studies on the impact of pre-operative infliximab use on short-term post-operative complications in ulcerative colitis. Infectious complications mainly included wound infection, sepsis and abscess, whereas non-infectious complications included intestinal obstruction, thromboembolism and gastrointestinal haemorrhage. Pooled odds ratios (ORs) were calculated for each relationship. A total of 5 studies and 706 patients were included in our meta-analysis. Overall, we did not find a strong association between pre-operative treatment of infliximab and short-term infectious [OR 2.24, 95% confidence interval (CI) 0.63-7.95] or non-infectious (OR 0.85, 95% CI 0.50-1.45) post-operative complications in ulcerative colitis patients. On the contrary, we discovered that pre-operative infliximab use increased short-term total post-operative complications (OR 1.80, 95% CI 1.12-2.87). Pre-operative infliximab use increased the risk of short-term post-operative complications. Subgroup analysis is underpowered to assess the nature of these complications but shows a trend towards increased post-operative infection.

Spectrum of sodium hypochlorite toxicity in man—also a concern for nephrologists

Sodium hypochlorite (NaOCl) is the active ingredient in household bleach and is a very common chemical. It has been used in medical and commercial situations dating back to the 18th century for its disinfectant properties, including topical use in medicine as an antiseptic. For this indication, NaOCl is a proven and safe chemical. However, exposure of NaOCl beyond topical use, whether it is intentional or accidental, is associated with significant risks due to its strong oxidizing properties. Potentially damaging scenarios include ingestion, inhalation, deposition into tissue or injection into the bloodstream. All of these scenarios can lead to significant morbidity and even mortality. In this review, we examine the toxicity associated with NaOCl exposure and analyze potential mechanisms of injury, placing special emphasis on the potential for renal toxicity. Due to the extreme ease of access to household bleach products and its use in medicine, it is important for the clinician to understand the potential damage that can occur in NaOCl exposures so that complications can be prevented before they arise.

Within the national dataset, we identified 17 623 major head and neck cancer resections between 2002 and 2012. There were 12 413 males and mean age at surgery was 63 ± 12 years. The commonest cancer site strata were oral cavity (42%) and larynx-hypopharynx (32%). The commonest resection site was the larynx (n = 4217), and 13 211 and 11 841 patients had neck dissection and flap-based reconstruction, respectively. There were prognostically significant baseline differences between patients with oromandibular and pharyngolaryngeal malignancy. Patients with pharyngolaryngeal malignancies had a greater burden of morbidities, lower socio-economic status, fewer primary resections, and a sixfold increased risk of undergoing their major resection during an emergency hospital admission. Mean length of stay was 25 days and each complication linearly increased it by 9.6 days. There were 609 (3.5%) in-hospital deaths and a basket of seven medical and three surgical complications significantly increased the risk of in-hospital death. At least one potentially lethal complication occurred in 26% of patients. The risk of in-hospital death in a patient with no potentially lethal complication was 1.1% and this increased to 6% with one potentially lethal complication, and to 15.1% if two potentially lethal complications occurred in one patient. Complex oral-pharyngeal resections and pharyngolaryngectomies had the highest risks of complications and mortality. Mortality following head and neck cancer surgery shows variation across different resection strata. We propose an Informatics-based Framework for Outcomes Surveillance (IFOS) in Head and Neck Surgery for perpetual quality assurance, using the local hospital coding data or its collated destination, the national administrative dataset. © 2016 John Wiley & Sons Ltd.

Guillain-Barré syndrome (GBS) is an immune-mediated disorder in the peripheral nervous system with a wide spectrum of complications. A good understanding of the complications of GBS assists clinicians to recognize and manage the complications properly thereby reducing the mortality and morbidity of GBS patients. Herein, we systemically review the literature on complications of GBS, including short-term complications and long-term complications. We summarize the frequency, severity, clinical manifestations, managements and possible mechanisms of different kinds of complications, and point out the flaws of current studies as well as demonstrate the further investigations needed.

Objective Surgical complications may affect patients psychologically due to challenges such as prolonged recovery or long-lasting disability. Psychological distress could further delay patients’ recovery as stress delays wound healing and compromises immunity. This review investigates whether surgical complications adversely affect patients’ postoperative well-being and the duration of this impact. Methods The primary data sources were ‘PsychINFO’, ‘EMBASE’ and ‘MEDLINE’ through OvidSP (year 2000 to May 2012). The reference lists of eligible articles were also reviewed. Studies were eligible if they measured the association of complications after major surgery from 4 surgical specialties (ie, cardiac, thoracic, gastrointestinal and vascular) with adult patients’ postoperative psychosocial outcomes using validated tools or psychological assessment. 13 605 articles were identified. 2 researchers independently extracted information from the included articles on study aims, participants’ characteristics, study design, surgical procedures, surgical complications, psychosocial outcomes and findings. The studies were synthesised narratively (ie, using text). Supplementary meta-analyses of the impact of surgical complications on psychosocial outcomes were also conducted. Results 50 studies were included in the narrative synthesis. Two-thirds of the studies found that patients who suffered surgical complications had significantly worse postoperative psychosocial outcomes even after controlling for preoperative psychosocial outcomes, clinical and demographic factors. Half of the studies with significant findings reported significant adverse effects of complications on patient psychosocial outcomes at 12 months (or more) postsurgery. 3 supplementary meta-analyses were completed, 1 on anxiety (including 2 studies) and 2 on physical and mental quality of life (including 3 studies). The latter indicated statistically significantly lower physical and mental quality of life (p<0.001) for patients who suffered surgical complications. Conclusions Surgical complications appear to be a significant and often long-term predictor of patient postoperative psychosocial outcomes. The results highlight the importance of attending to patients’ psychological needs in the aftermath of surgical complications. PMID:26883234

2016-01-01

Given the expression of ABO blood group antigens on the surface of a wide range of human cells and tissues, the putative interplay of the ABO system in human biology outside the area of transfusion and transplantation medicine constitutes an intriguing byway of research. Thanks to evidence accumulated over more than 50 years, the involvement of the ABO system in the pathogenesis of several human diseases, including cardiovascular, infectious and neoplastic disorders, is now acknowledged. However, there is controversial information on the potential association between ABO blood type and adverse pregnancy outcomes, including pre-eclampsia and related disorders (eclampsia, HELLP syndrome and intrauterine growth restriction), venous thromboembolism, post-partum haemorrhage and gestational diabetes. To elucidate the role of ABO antigens in pregnancy-related complications, we performed a systematic review of the literature published in the past 50 years. A meta-analytical approach was also applied to the existing literature on the association between ABO status and pre-eclampsia. The results of this systematic review are presented and critically discussed, along with the possible pathogenic implications. PMID:27177402

Laparoscopic Pediatric Inguinal Hernia Repair: Overview of "True Herniotomy" Technique and Review of Current Evidence.

PubMed

Feehan, Brendan P; Fromm, David S

2017-05-01

Inguinal hernia repair is one of the most commonly performed operations in the pediatric population. While the majority of pediatric surgeons routinely use laparoscopy in their practices, a relatively small number prefer a laparoscopic inguinal hernia repair over the traditional open repair. This article provides an overview of the three port laparoscopic technique for inguinal hernia repair, as well as a review of the current evidence with respect to visualization and identification of hernias, recurrence rates, operative times, complication rates, postoperative pain, and cosmesis. The laparoscopic repair presents a viable alternative to open repair and offers a number of benefits over the traditional approach. These include superior visualization of the relevant anatomy, ability to assess and repair a contralateral hernia, lower rates of metachronous hernia, shorter operative times in bilateral hernia, and the potential for lower complication rates and improved cosmesis. This is accomplished without increasing recurrence rates or postoperative pain. Further research comparing the different approaches, including standardization of techniques and large randomized controlled trials, will be needed to definitively determine which is superior.

Effectiveness of electrocardiographic guidance in CVAD tip placement.

PubMed

Walker, Graham; Chan, Raymond J; Alexandrou, Evan; Webster, Joan; Rickard, Claire

International standard practice for the correct confirmation of the central venous access device is the chest X-ray. The intracavitary electrocardiogram-based insertion method is radiation-free, and allows real-time placement verification, providing immediate treatment and reduced requirement for post-procedural repositioning. Relevant databases were searched for prospective randomised controlled trials (RCTs) or quasi RCTs that compared the effectiveness of electrocardiogram-guided catheter tip positioning with placement using surface-anatomy-guided insertion plus chest X-ray confirmation. The primary outcome was accurate catheter tip placement. Secondary outcomes included complications, patient satisfaction and costs. Five studies involving 729 participants were included. Electrocardiogram-guided insertion was more accurate than surface anatomy guided insertion (odds ratio: 8.3; 95% confidence interval (CI) 1.38; 50.07; p=0.02). There was a lack of reporting on complications, patient satisfaction and costs. The evidence suggests that intracavitary electrocardiogram-based positioning is superior to surface-anatomy-guided positioning of central venous access devices, leading to significantly more successful placements. This technique could potentially remove the requirement for post-procedural chest X-ray, especially during peripherally inserted central catheter (PICC) line insertion.

Infected abdominal defects are a challenge to surgeons. In this study, we describe 10 cases in which the latissimus dorsi myocutaneous flap was used for successful reconstruction of abdominal wall defects severely infected with methicillin-resistant Staphylococcus aureus (MRSA). Retrospective review of 10 patients with abdominal wall defects that were reconstructed using the latissimus dorsi myocutaneous flap between 2002 and 2010. All patients had abdominal defects with hernias, combined with MRSA infections. The sizes of the flaps ranged from 120 to 364 cm(2) . The deep inferior epigastric artery was the recipient vessel in nine patients and the internal mammary vessels were used for one patient. There were no complications relating to the flaps, although there were other minor complications including wound dehiscence, haematoma and fluid correction. After reconstruction, there were no signs of infection during follow-up periods, and the patients were satisfied with the final results. Reconstruction using the latissimus dorsi myocutaneous flap, including muscle fascia structures, is a potential treatment option for severely infected large abdominal wall defects. © 2012 The Authors.

Fatal methane and cyanide poisoning as a result of handling industrial fish: a case report and review of the literature.

PubMed

Cherian, M A; Richmond, I

2000-10-01

The potential health hazards of handling industrial fish are well documented. Wet fish in storage consume oxygen and produce poisonous gases as they spoil. In addition to oxygen depletion, various noxious agents have been demonstrated in association with spoilage including carbon dioxide, sulphur dioxide, and ammonia. A fatal case of methane and cyanide poisoning among a group of deep sea trawler men is described. Subsequent independent investigation as a result of this case led to the discovery of cyanides as a further potential noxious agent. This is thus the first case in which cyanide poisoning has been recognised as a potentially fatal complication of handling spoiled fish. The previous literature is reviewed and the implications of the current case are discussed.

2016-11-01

Minimally invasive live donor nephrectomy has become a fully implemented and accepted procedure. Donors have to be well educated about all risks and details during the informed consent process. For this to be successful, more information regarding short-term outcome is necessary. A literature search was performed; all studies discussing short-term complications after minimally invasive live donor nephrectomy were included. Outcomes evaluated were intraoperative and postoperative complications, conversions, operative and warm ischemia times, blood loss, length of hospital stay, pain score, convalescence, quality of life, and costs. One hundred ninety articles were included in the systematic review, 41 in the meta-analysis. Conversion rate was 1.1%. Intraoperative complication rate was 2.3%, mainly bleeding (1.5%). Postoperative complications occurred in 7.3% of donors, including infectious complications (2.6%), of which mainly wound infection (1.6%) and bleeding (1.0%). Reported mortality rate was 0.01%. All minimally invasive techniques were comparable with regard to complication or conversion rate. The used techniques for minimally invasive live donor nephrectomy are safe and associated with low complication rates and minimal risk of mortality. These data may be helpful to develop a standardized, donor-tailored informed consent procedure for live donor nephrectomy.

Background. Tube thoracostomy is widely used throughout the medical, surgical, and critical care specialities. It is generally used to drain pleural collections either as elective or emergency. Complications resulting from tube thoracostomy can occasionally be life threatening. Aim. To present an update on the complications and management of complications of tube thoracostomy. Methods. A review of the publications obtained from Medline search, medical libraries, and Google on tube thoracostomy and its complications was done. Results. Tube thoracostomy is a common surgical procedure which can be performed by either the blunt dissection technique or the trocar technique. Complication rates are increased by the trocar technique. These complications have been broadly classified as either technical or infective. Technical causes include tube malposition, blocked drain, chest drain dislodgement, reexpansion pulmonary edema, subcutaneous emphysema, nerve injuries, cardiac and vascular injuries, oesophageal injuries, residual/postextubation pneumothorax, fistulae, tumor recurrence at insertion site, herniation through the site of thoracostomy, chylothorax, and cardiac dysrhythmias. Infective complications include empyema and surgical site infection. Conclusion. Tube thoracostomy, though commonly performed is not without risk. Blunt dissection technique has lower risk of complications and is hence recommended. PMID:22028963

The objective of the study was to describe the clinical and epidemiological characteristics of complicated chickenpox cases seen at the National Institute of Children's Health (INSN, Spanish acronym) of Peru from 2001 to 2011. A case series was collected, including a total of 1,073 children with complicated chickenpox. The median age was 2.5 years (IQR 1.1-4.8 years), of which 578 (54%) were male. The most frequent complications were secondary skin and soft tissue infections with 768 cases (72%). 13 deaths (1.4%) were recorded. In conclusion, the hospitalizations due to complicated chickenpox in the INSN included mostly children under five, with a short stay and a low proportion of deaths most complications being related to secondary skin and soft tissue infections.

Traumatic brain injury (TBI) is an important health issue with high mortality. Various complications of physiological and cognitive impairment may result in disability or death after TBI. Grouping of these complications could be treated as integrated post-TBI syndromes. To improve risk estimation, grouping TBI complications should be investigated, to better predict TBI mortality. This study aimed to estimate mortality risk based on grouping of complications among TBI patients. Taiwan's National Health Insurance Research Database was used in this study. TBI was defined according to the International Classification of Diseases, Ninth Revision, Clinical Modification codes: 801-804 and 850-854. The association rule data mining method was used to analyze coexisting complications after TBI. The mortality risk of post-TBI complication sets with the potential risk factors was estimated using Cox regression. A total 139,254 TBI patients were enrolled in this study. Intracerebral hemorrhage was the most common complication among TBI patients. After frequent item set mining, the most common post-TBI grouping of complications comprised pneumonia caused by acute respiratory failure (ARF) and urinary tract infection, with mortality risk 1.55 (95% C.I.: 1.51-1.60), compared with those without the selected combinations. TBI patients with the combined combinations have high mortality risk, especially those aged <20 years with septicemia, pneumonia, and ARF (HR: 4.95, 95% C.I.: 3.55-6.88). We used post-TBI complication sets to estimate mortality risk among TBI patients. According to the combinations determined by mining, especially the combination of septicemia with pneumonia and ARF, TBI patients have a 1.73-fold increased mortality risk, after controlling for potential demographic and clinical confounders. TBI patients aged<20 years with each combination of complications also have increased mortality risk. These results could provide physicians and caregivers with important information to increase their awareness about sequences of clinical syndromes among TBI patients, to prevent possible deaths among these patients.

For radical cystectomy, historical practice trends have favored the use of preoperative bowel preparations to reduce complications, including surgical site infections, ileus, and anastomotic leaks. However, emerging data has questioned this practice. Postoperative cystectomy care also remains in flux, as new pharmacologic agents that may potentiate earlier return of bowel function are studied. We review the current literature with regards to preoperative and postoperative cystectomy bowel management.

Postdural puncture headache (PDPH) is a recognized complication of neuraxial anesthesia. This case report documents 1 patient who developed PDPH following epidural anesthesia for postoperative pain control. The patient declined conventional treatments, including an epidural blood patch and intravenous caffeine. This report documents successful use of adjunct acupuncture for the management of PDPH. Additional research on acupuncture as a potential adjunctive therapy for PDPH is needed, particularly for patients who are reluctant to receive more invasive treatments. PMID:26937320

Obesity is the most prevalent nutritional disease and a growing public health problem worldwide. This disease is a causal component of the metabolic syndrome related with abnormalities, including hyperglycemia, dyslipidemia, hypertension, inflammation, among others. There are anti-obesity drugs, affecting the fundamental processes of the weight regulation; however they have shown serious side effects, which outweigh their beneficial effects. Most recent studies on the treatment of obesity and its complications have focused on the potential role of different plants preparation that can exert a positive effect on the mechanisms involved in this pathology. For instance, anti-obesity effects of green tea and its isolated active principles have been reported in both in vitro (cell cultures) and in vivo (animal models) that possess healthy effects, decreasing adipose tissue through reduction of adipocytes differentiation and proliferation. A positive effect in lipid profile, and lipid and carbohydrates metabolisms were demonstrated as well. In addition, anti-inflammatory and antioxidant activities were studied. However, the consumption of green tea and its products is not that common in Western countries, where other plants with similar bioactivity predominate; nevertheless, the effect extension has not been analyzed in depth, despite of their potential as alternative treatment for obesity. In this review the anti-obesity potential and reported mechanisms of action of diverse plants such as: Camellia sinensis, Hibiscus sabdariffa, Hypericum perforatum, Persea americana, Phaseolus vulgaris, Capsicum annuum, Rosmarinus officinalis, Ilex paraguariensis, Citrus paradisi, Citrus limon, Punica granatum, Aloe vera, Taraxacum officinale and Arachis hypogaea is summarized. We consider the potential of these plants as natural alternative treatments of some metabolic alterations associated with obesity. PMID:26869866

Right lobar living donor living transplantation (LDLT) has been controversial because of widely differing reports of recipient morbidity. Herein, we present our nearly 10-year experience and identify factors that potentially could be modified to improve recipient outcome. The Clavien 5-tier grading system was applied retrospectively in 196 consecutive adult right lobar recipients. We determined the incidence of potentially life- threatening (Grade III), actually life-threatening (Grade IV), and lethal (Grade V) complications during the first post-transplant year. The most serious and seminal complication was considered if simultaneous or multiple complications appeared. One-year recipient/graft survival was 82%/82%. Within the first year, 68 (34.69%) of the 196 recipients had Grade III (n=31), Grade IV (n=7), or Grade V (n=30) complications. The complications were 19.90% graft-related and 15.82% non-graft-related. Complications during the first half year did not decline with increased team experience over time and adversely affected recipients' long-term survival, albeit not significantly. According to univariate analysis, high Child-Pugh scores before transplantation (P=0.016), prolonged ICU-stay (P=0.003) and hospitalization time (P=0.032) after transplantation were found to be risk factors for the appearance of ≥ Clavien III complications, while duct-to-duct biliary reconstruction (P=0.02) had a beneficial role in reducing serious complications after LDLTs. In conclusion, serious complications during the first post-transplant year shortened recipient survival and prolonged primary hospitalization duration and postoperative ICU-stay, which is more frequent in recipients with higher Child-Pugh scores and in those with hepaticojejunostomy.

Cost-effectiveness of a novel blood-pool contrast agent in the setting of chest pain evaluation in an emergency department.

2013-10-01

We evaluated three diagnostic strategies with the objective of comparing the current standard of care for individuals presenting acute chest pain and no history of coronary artery disease (CAD) with a novel diagnostic strategy using an emerging technology (blood-pool contrast agent [BPCA]) to identify the potential benefits and cost reductions. A decision analytic model of diagnostic strategies and outcomes using a BPCA and a conventional agent for CT angiography (CTA) in patients with acute chest pain was built. The model was used to evaluate three diagnostic strategies: CTA using a BPCA followed by invasive coronary angiography (ICA), CTA using a conventional agent followed by ICA, and ICA alone. The use of the two CTA-based triage tests before ICA in a population with a CAD prevalence of less than 47% was predicted to be more cost-effective than ICA alone. Using the base-case values and a cost premium for BPCA over the conventional CT agent (cost of BPCA ≈ 5× that of a conventional agent) showed that CTA with a BPCA before ICA resulted in the most cost-effective strategy; the other strategies were ruled out by simple dominance. The model strongly depends on the rates of complications from the diagnostic tests included in the model. In a population with an elevated risk of contrast-induced nephropathy (CIN), a significant premium cost per BPCA dose still resulted in the alternative whereby CTA using BPCA was more cost-effective than CTA using a conventional agent. A similar effect was observed for potential complications resulting from the BPCA injection. Conversely, in the presence of a similar complication rate from BPCA, the diagnostic strategy of CTA using a conventional agent would be the optimal alternative. BPCAs could have a significant impact in the diagnosis of acute chest pain, in particular for populations with high incidences of CIN. In addition, a BPCA strategy could garner further savings if currently excluded phenomena including renal disease and incidental findings were included in the decision model.

To conduct a retrospective observational cohort study to estimate the abortion complication rate, including those diagnosed or treated at emergency departments (EDs). Using 2009-2010 abortion data among women covered by the fee-for-service California Medicaid program and all subsequent health care for 6 weeks after having an abortion, we analyzed reasons for ED visits and estimated the abortion-related complication rate and the adjusted relative risk. Complications were defined as receiving an abortion-related diagnosis or treatment at any source of care within 6 weeks after an abortion. Major complications were defined as requiring hospital admission, surgery, or blood transfusion. A total of 54,911 abortions among 50,273 fee-for-service Medi-Cal beneficiaries were identified. Among all abortions, 1 of 16 (6.4%, n=3,531) was followed by an ED visit within 6 weeks but only 1 of 115 (0.87%, n=478) resulted in an ED visit for an abortion-related complication. Approximately 1 of 5,491 (0.03%, n=15) involved ambulance transfers to EDs on the day of the abortion. The major complication rate was 0.23% (n=126, 1/436): 0.31% (n=35) for medication abortion, 0.16% (n=57) for first-trimester aspiration abortion, and 0.41% (n=34) for second-trimester or later procedures. The total abortion-related complication rate including all sources of care including EDs and the original abortion facility was 2.1% (n=1,156): 5.2% (n=588) for medication abortion, 1.3% (n=438) for first-trimester aspiration abortion, and 1.5% (n=130) for second-trimester or later procedures. Abortion complication rates are comparable to previously published rates even when ED visits are included and there is no loss to follow-up. II.

Potential therapeutic value of TRPV1 and TRPA1 in diabetes mellitus and obesity.

Diabetes mellitus and obesity, which is a major risk factor in the development of type 2 diabetes mellitus, have reached epidemic proportions worldwide including the USA. The current statistics and forecasts, both short- and long-term, are alarming and predict severe problems in the near future. Therefore, there is a race for developing new compounds, discovering new receptors, or finding alternative solutions to prevent and/or treat the symptoms and complications related to obesity and diabetes mellitus. It is well demonstrated that members of the transient receptor potential (TRP) superfamily play a crucial role in a variety of biological functions both in health and disease. In the recent years, transient receptor potential vanilloid type 1 (TRPV1) and transient receptor potential ankyrin 1 (TRPA1) were shown to have beneficial effects on whole body metabolism including glucose homeostasis. TRPV1 and TRPA1 have been associated with control of weight, pancreatic function, hormone secretion, thermogenesis, and neuronal function, which suggest a potential therapeutic value of these channels. This review summarizes recent findings regarding TRPV1 and TRPA1 in association with whole body metabolism with emphasis on obese and diabetic conditions.

To compare the rates of intraoperative and postoperative complications of robotic surgery and laparoscopy in the surgical treatment of endometrial cancer. Unicentric retrospective study (Canadian Task Force classification II-2). Tertiary teaching hospital. The study was performed from January 2002 to December 2011 and included patients with endometrial cancer who underwent laparoscopic or robotically assisted laparoscopic surgical treatment. Data collected included preoperative data, tumor characteristics, intraoperative data (route of surgery, surgical procedures, and complications), and postoperative data (early and late complications according to the Clavien-Dindo classification, and length of hospital stay). Morbidity was compared between the 2 groups. The study included 146 patients, of whom 106 underwent laparoscopy and 40 underwent robotically assisted surgery. The 2 groups were comparable in terms of demographic and preoperative data. Intraoperative complications occurred in 9.4% of patients who underwent laparoscopy and in none who underwent robotically assisted surgery (p = .06). There was no difference between the 2 groups in terms of postoperative events. Robotically assisted surgery is not associated with a significant difference in intraoperative and postoperative complications, even when there were no intraoperative complications of robotically assisted surgery.

Auricular deformities, specifically, prominent ears, are relatively frequent. Although the physiologic consequences are negligible, the aesthetic and psychological effects on the patient can be substantial. Otoplasty techniques are used to correct many auricular deformities, including the prominent ear, the constricted ear, Stahl's deformity, and cryptotia. Various treatments and techniques have been developed for the correction of these deformities, including methods that excise, bend, suture, scratch, or reposition the auricular cartilage. The multitude of different approaches indicates that there is not one clearly definitive technique for correcting these problems. This article reviews the history of otoplasty, its anatomical basis and a method for evaluation, techniques for the correction of the deformity, and potential complications of the procedure.

2017-11-01

Postoperative pancreas-related complications are quite uncommon but potentially life-threatening occurrences that may occasionally complicate the postoperative course of gastrectomy. A number of reports have described such conditions after both standard open and minimally invasive surgery. Our study has the purpose to systematically determine the pooled incidence of pancreatic events following radical gastrectomy. We also aimed to elucidate whether any difference in incidence exists between patients operated via conventional open or minimally invasive surgery. PubMed, EMBASE, and the Cochrane Library were systematically searched for randomized or well-matched studies comparing conventional with minimally invasive oncological gastrectomy and reporting pancreas-related postoperative complications. We evaluated possible differences in outcomes between open and minimally invasive surgery. A meta-analysis of relevant comparisons was performed using RevMan 5.3. A total of 20 studies, whereby 6 randomized and 14 non-randomized comparative studies including a total of 7336 patients, were considered eligible for data extraction. Globally, more than 1% of patients experienced some pancreatic occurrences during the postoperative course. The use of minimally invasive surgery showed a trend toward increased overall pancreatic morbidity (OR 1.39), pancreatitis (OR 2.69), and pancreatic fistula (OR 1.13). Although minimally invasive radical gastrectomy is currently established as a valid alternative to open surgery for the treatment of gastric cancer, a higher risk of pancreas-related morbidity should be taken into account.

Extraction of third molars is the most common surgical procedure performed in oral surgery on a daily basis and, despite surgical skills and expertise, complications may occur. Complications observed during or after third molar removal may include pain, swelling, bleeding, infection, sinus perforation and nerve damage. Fortunately, with a proper management and a good surgical technique, the incidence of such events is low. Subcutaneous emphysema associated with dental extraction occurs when the air from the high-speed dental handpiece is forced into the soft tissue through the reflected flap and invades the adjacent tissues, leading to swelling, crepitus on palpation and occasionally spreading through the tissue spaces of the fascial planes. Although rare, iatrogenic subcutaneous emphysema can have serious and potentially life-threatening consequences. Care should be taken when using air-driven handpieces. The access of air into the facial tissues is not limited to tooth extractions, but may also occur through other portals of entrance, such as endodontically treated teeth, periodontium and lacerations of intraoral soft tissues. When subcutaneous emphysema occurs, it must be quickly diagnosed and properly managed to reduce the risk of further complications. This report presents a case of subcutaneous emphysema occurred during extraction of a mandibular third molar extraction with the use of an air turbine handpiece. Case management is described and issues relative to the diagnosis and prevention of this surgical complication are discussed.

Q fever is an ubiquitous zoonosis caused by Coxiella burnetii. Its tropism for the uterus is a potential source of obstetric complications. We describe the obstetric consequences of Q fever diagnosed during pregnancy from a series of cases. When an antenatal diagnosis was made, antibiotic therapy with roxithromycin (Rulid(®)) was started until delivery. Between 2007 and 2012, 30 patients were treated for Q fever diagnosed during pregnancy, i.e. 1.9 cases per 1000 people. The most common reasons for performing serology was intrauterine growth retardation, preterm labor and oligoamnios. Q fever was diagnosed as acute and chronic in 26 and 4 cases, respectively. Progression to chronic disease occurred in 8 % of acute forms of the diseases. The prevalence of obstetric complications was 66 %, including 10 % foetal deaths, 31 % preterm delivery and 27 % low birthweight <10th percentile. The obstetric complication rate amongst the 22 patients treated with ante partum macrolides was 60, 30 % of which involved prematurity and 33 % involved low growth. No cases of foetal death were found on treatment and no congenital malformation and placental or neonatal injury was found. No case of disease reactivation was diagnosed in the eight patients who became pregnant again. Q fever during pregnancy is responsible for severe obstetric complications. It must be diagnosed early and its clinical forms known in order to start appropriate antibiotic therapy.

Zingiber officinale is being used as diet-based therapy because of its wide therapeutic potential in type 2 diabetes mellitus (T2DM) and against diabetic complications by directly interacting with different molecular and cellular pathways that provoke the pathogenesis of T2DM. This article explores the overall beneficial effects of Z. officinale on T2DM and its associated complications. Along with elucidating the beneficial facts of Z. officinale, this article may also aid in understanding the molecular basis of its effects in T2DM. The mechanistic rationale for antidiabetic effects of Z. officinale includes the inhibition of several transcriptional pathways, lipid peroxidation, carbohydrate-metabolizing enzymes, and HMG-CoA reductase and the activation of antioxidant enzyme capacity and low-density lipoprotein receptors. Consequently, by targeting these pathways, Z. officinale shows its antidiabetic therapeutic effects by increasing insulin sensitivity/synthesis, protecting β-cells of pancreatic islets, reducing fat accumulation, decreasing oxidative stress, and increasing glucose uptake by the tissues. In addition to these effects, Z. officinale also exhibits protective effects against several diabetes-linked complications, notably nephropathy and diabetic cataract, by acting as an antioxidant and antiglycating agent. In conclusion, this work suggests that consumption of Z. officinale can help to treat T2DM and diabetic complications; nevertheless, patient counseling also is required as a guiding force for the success of diet-based therapy in T2DM.

Surgery is a major stress factor that activates several inflammatory and catabolic pathways in man. An appropriate nutritional status allows the body to react properly to this stressor and recover in a faster and more efficient manner. On the other hand, malnutrition is related to a worse surgery outcome and to a higher prevalence of comorbidities and mortality. The aims of this study were to evaluate the nutritional status of patients undergoing major surgery and investigate the potential correlation between malnutrition and surgical outcomes. Mini Nutritional Assessment (MNA) and global clinical examination (including biochemical parameters and comorbidities existence) were undertaken in 50 consecutive patients undergoing major surgery. Patients' clinical conditions were re-evaluated at 3 and 6 days after surgery, recording biochemical parameters and systemic and/or wound-related complications. A compromised nutritional status was present in more than half (54%) of patients (malnutrition in 10% and risk of malnutrition in 44% of patients, respectively). Females were slightly more at risk of malnutrition (48% vs. 41%, p=NS, females vs. males) and clearly malnourished (14% vs. 7%, p<0.05, females vs. males). Age was an independent risk factor for malnutrition and within the elders' group (> 80 years old) 16.70% of patients was diagnosed with malnutrition and 58.3% was at risk of malnutrition. Systemic complications were registered in all patients both at 3 and 6 days after surgery. However, well-nourished and at-risk of malnutrition patients had earlier complications that only partially resolved within six days after the operation. Malnourished patients showed fewer complications at the 3rd post-surgery follow-up day but had a worse outcome six days after surgery. Older age and but not female sex are independent risk factors for malnutrition development in patients undergoing major surgery. More interestingly, more than half of patients with an impaired nutritional status presented a less appropriated stress response to surgery. These data suggest that nutritional status assessment may be important to recognize patients at potential risk of surgical complications and that early nutritional interventions must be promptly arranged.

A new strategy for otoplasty.

Shokrollahi, K; Cooper, M A; Hiew, L Y

Pinnaplasty using the Mustardé and Furnas techniques is increasingly popular. One adjunctive technique that is often used involves the elevation of a fascial flap beneath which sutures are placed for additional cover, potentially reducing the risk of complications and possibly recurrence. This flap is traditionally raised with a proximal base, but it can be raised distally with a number of advantages as we illustrate. More significantly, we demonstrate the potential for an entirely new operation to correct prominent ears with benefits including a natural end result, simplicity, reduced operative time, less tissue trauma and the use of a single buried knot. We illustrate the use of this procedure adjunctively to reinforce suture-based techniques in a series of 15 patients.

An auditory-neuroscience perspective on the development of selective mutism.

Selective mutism (SM) is a relatively rare psychiatric disorder of childhood characterized by consistent inability to speak in specific social situations despite the ability to speak normally in others. SM typically involves severe impairments in social and academic functioning. Common complications include school failure, social difficulties in the peer group, and aggravated intra-familial relationships. Although SM has been described in the medical and psychological literatures for many years, the potential underlying neural basis of the disorder has only recently been explored. Here we explore the potential role of specific auditory neural mechanisms in the psychopathology of SM and discuss possible implications for treatment. Copyright © 2015 The Authors.

2017-11-01

A lower incidence of cardiovascular events has been reported in type 2 diabetes patients treated with insulin analogs (IAs). Corresponding data on people affected by type 1 diabetes are not available yet. We investigated demographic and clinical data from 509 type 1 diabetics, who were treated in an outpatient clinic from 2006 to 2012. Multiple logistic regression was used to investigate the relationship between the type of insulin treatment and the prevalence of cardiovascular (CV) complications, that is, presence of coronary heart, cerebrovascular and peripheral arterial diseases, adjusting for potential confounders. Results from multiple logistic regression revealed that patients with impaired renal function [estimated glomerular filtration rate (eGFR) < 90 ml/min] show lower CV complication rates when treated with IAs (25%) compared with patients treated with human insulin (HI; 28%) and HI/IA (38%, p = 0.06). CV complication rates in the complete patient collective amounted to 17% (IA), 21% (HI) and 21% (HI/IA, p = 0.08). Examination of CV complications according to the type of IA revealed the lowest complication rates in type 1 diabetics treated with insulin lispro (5.9%) and glargine (16%). However, complication rate differences among insulin treatments did not reach statistical significance. The present cross-sectional study shows a borderline significantly lower CV morbidity in people with type 1 diabetes and impaired renal function when treated with IA compared with HI treatment after adjustment for multiple potential confounders [odds ratio (OR) = 0.78, which translates into a 22% lower complication rate]. Validation of these preliminary findings in confirmatory, prospective studies may have important clinical implications.

The Trauma Quality Improvement Program has demonstrated existence of significant variations in risk-adjusted mortality across trauma centers. However, it is unknown whether centers with lower mortality rates also have reduced length of stay (LOS), with associated cost savings. We hypothesized that LOS is not primarily determined by unmodifiable factors, such as age and injury severity, but is primarily dependent on the development of potentially preventable complications. The National Trauma Data Bank (2002-2006) was used to include patients (older than 16 years) with at least one severe injury (Abbreviated Injury Scale score ≥ 3) from Level I and II trauma centers (217,610 patients, 151 centers). A previously validated risk-adjustment algorithm was used to calculate observed-to-expected mortality ratios for each center. Poisson regression was used to determine the relationship between LOS, observed-to-expected mortality ratios, and complications while controlling for confounding factors, such as age, gender, mechanism, insurance status, comorbidities, and injuries and their severity. Large variations in LOS (median, 4-8 days) were observed across trauma centers. There was no relationship between mortality and LOS. The most important predictor of LOS was complications, which were associated with a 62% increase. Injury severity score, shock, gunshot wounds, brain injuries, intensive care unit admission, and comorbidities were less important predictors of LOS. Quality improvement programs focusing on mortality alone may not be associated with reduced LOS. Hence, the Trauma Quality Improvement Program should also focus on processes of care that reduce complications, thereby shortening LOS, which may lead to significant cost savings at trauma centers.

Closed-incision negative-pressure therapy in high-risk general surgery patients following laparotomy: a retrospective study.

Surgical site infection (SSI) and wound dehiscence are dreaded complications following laparotomy in general surgical patients, and can potentially occur more often in various comorbid states. Negative-pressure wound therapy (NPWT) has a positive effect of on open and complicated wounds and so has been used for at-risk surgical incisions with the aim of redistributing lateral tension and holding incision edges together. The aim of the present study was to compare the rate of wound complications following laparotomy in high-risk general surgical patients with a clean incision treated with closed-incision negative-pressure therapy (ciNPT) with those receiving conventional care. A retrospective review was performed of the hospital medical records of patients who underwent laparotomy between 1 October 2010 and 31 March 2012. Records of 69 patients who received ciNPT and 112 who were managed by adherent gauze dressings were included in the final analysis. Two (2.9%) patients in the ciNPT group and 23 (20.5%) in the non-NPWT group developed a wound complication following laparotomy (P < 0.0009). The relative risk (RR) was 0.14 (0.03-0.58), suggesting that infection is less likely to occur in ciNPT-treated incisions, compared with gauze dressings. ciNPT was associated with a positive clinical outcome and was a safe and effective method of postsurgical management in our general surgery patients considered to have risk of developing wound complications following laparotomy. © 2016 The Authors.

To determine if postoperative urinary retention and urinary tract infections (UTIs) were predictors of future mesh complications requiring surgical intervention after midurethral sling (MUS). Administrative data in Ontario, Canada, between 2002 and 2013 were used to identify all women who underwent a mesh-based MUS. The primary outcome was revision of the transvaginal mesh sling (including mesh removal/erosion/fistula, or urethrolysis). Two potential risk factors were analyzed: postoperative retention (within 30 days of procedure) and number of postoperative emergency room visits or hospital admissions for UTI symptoms. A total of 59,556 women had a MUS, of which 1598 (2.7%) required revision surgery. Of the 2025 women who presented to the emergency room or were admitted to hospital for postoperative retention, 212 (10.5%) required operative mesh revision. Of the 11,747 patients who had at least one postoperative UTI, 366 (3.1%) patients required operative mesh revision. In adjusted analysis, postoperative retention was significantly predictive of future reoperation (hazard ratio [HR] 3.46, 95% confidence interval [CI] 2.97-4.02), and this difference persisted when urethrolysis was excluded as a reason for sling revision (HR 3.08, 95% CI 2.62-3.63). Similarly, in adjusted analysis, each additional postoperative hospital visit for UTI symptoms increased the risk for surgical intervention for mesh complications (HR 1.74, 95% CI 1.61-1.87). Postoperative urinary retention and hospital presentation for UTI symptoms are associated with an increased risk of reoperation for MUS complications. These patients should be followed and investigated for mesh complications when appropriate. Copyright © 2016 Elsevier Inc. All rights reserved.

ASD Closure in Structural Heart Disease.

2018-04-17

While the safety and efficacy of percutaneous ASD closure has been established, new data have recently emerged regarding the negative impact of residual iatrogenic ASD (iASD) following left heart structural interventions. Additionally, new devices with potential advantages have recently been studied. We will review here the potential indications for closure of iASD along with new generation closure devices and potential late complications requiring long-term follow-up. With the expansion of left-heart structural interventions and large-bore transseptal access, there has been growing experience gained with management of residual iASD. Some recently published reports have implicated residual iASD after these procedures as a potential source of diminished clinical outcomes and mortality. Additionally, recent trials investigating new generation closure devices as well as expanding knowledge regarding late complications of percutaneous ASD closure have been published. While percutaneous ASD closure is no longer a novel approach to managing septal defects, there are several contemporary issues related to residual iASD following large-bore transseptal access and new generation devices which serve as an impetus for this review. Ongoing attention to potential late complications and decreasing their incidence with ongoing study is clearly needed.

Global minimum profile error (GMPE) - a least-squares-based approach for extracting macroscopic rate coefficients for complex gas-phase chemical reactions.

2018-01-03

Master equation/Rice-Ramsperger-Kassel-Marcus (ME/RRKM) has shown to be a powerful framework for modeling kinetic and dynamic behaviors of a complex gas-phase chemical system on a complicated multiple-species and multiple-channel potential energy surface (PES) for a wide range of temperatures and pressures. Derived from the ME time-resolved species profiles, the macroscopic or phenomenological rate coefficients are essential for many reaction engineering applications including those in combustion and atmospheric chemistry. Therefore, in this study, a least-squares-based approach named Global Minimum Profile Error (GMPE) was proposed and implemented in the MultiSpecies-MultiChannel (MSMC) code (Int. J. Chem. Kinet., 2015, 47, 564) to extract macroscopic rate coefficients for such a complicated system. The capability and limitations of the new approach were discussed in several well-defined test cases.

Diagnosis and treatment of infectious mononucleosis.

PubMed

Bailey, R E

1994-03-01

Infectious mononucleosis is caused by the Epstein-Barr virus (EBV) and most commonly affects young adults from 15 to 35 years of age. The diagnosis is made by accurate assessment of clinical, hematologic and serologic manifestations of the illness. Manifestations include the classic triad of fever, pharyngitis and cervical lymphadenopathy; lymphocytosis with a predominance of atypical lymphocytes; a positive heterophil (Monospot) antibody test; and in some cases, serologic evidence of EBV-specific antibodies produced against antigens related to the virus. The most valuable serologic finding is the presence of IgM antibody to EBV viral capsid antigen, which is found during acute primary EBV infection. Infectious mononucleosis is considered a self-limited illness, but it may result in serious complications involving the pulmonary, ophthalmologic, neurologic and hematologic systems. Treatment is focused on managing the symptoms, unless more severe disease involving other organ systems occurs. The most common potentially fatal complication is splenic rupture.

Sepsis in general surgery: a deadly complication.

2009-12-01

Sepsis is a deadly and potentially preventable complication. A better understanding of sepsis in general surgery patients is needed to help direct resources to those patients at highest risk for death from sepsis. We identified risk factors for sepsis in general surgery patients by using the National Surgical Quality Improvement Project database. Analysis of the database identified 3 major risk factors for both the development of sepsis and death from sepsis in general surgery patients. These risk factors are age older than 60 years, need for emergency surgery, and the presence of comorbid conditions. Risk factors for death from sepsis or septic shock in general surgery patients include age older than 60 years, need for emergency surgery, and the presence of preexisting comorbidities. These findings emphasize the need for early recognition through aggressive sepsis screening and rapid implementation of evidence-based interventions for sepsis and septic shock in general surgery patients with these risk factors.

2008-04-01

Abscess of the residual lobe after lobectomy is a rare but potentially lethal complication. Between January 1975 and December 2006, 1,460 patients underwent elective pulmonary lobectomy for non-small-cell lung cancer at our institution. Abscess of the residual lung parenchyma occurred in 5 (0.3%) cases (4 bilobectomies and 1 lobectomy). Postoperative chest radiography showed incomplete expansion and consolidation of residual lung parenchyma. Flexible bronchoscopy revealed persistent bronchial occlusion from purulent secretions and/or bronchial collapse. Computed tomography in 3 patients demonstrated lung abscess foci. Surgical treatment included completion right pneumonectomy in 3 patients and a middle lobectomy in one. Complications after repeat thoracotomy comprised contralateral pneumonia and sepsis in 1 patient. Residual lobar abscess after lobectomy should be suspected in patients presenting with fever, leukocytosis, bronchial obstruction and lung consolidation despite antibiotic therapy, physiotherapy and bronchoscopy. Computed tomography is mandatory for early diagnosis. Surgical resection of the affected lobe is recommended.

New technology applications: thrombolysis of acute deep vein thrombosis.

PubMed

Marchigiano, Gail; Riendeau, Debra; Jo Morse, Carol

2006-01-01

Treatment of deep vein thrombosis traditionally has focused on preventing the potentially life-threatening complication of pulmonary embolism rather than on removing or reducing the thrombus. Although treatment with anticoagulants may prevent thrombus propagation, the body's intrinsic thrombolytic system is left to attempt clot dissolution. Because this natural process is generally ineffective in its ability to fully recanalize a proximal vein, the risks of recurrent thrombosis as well as the disabling complication of postthrombotic syndrome increase. Moreover, the long-term consequences of postthrombotic syndrome include pain, disability, and, for many, a significant decrease in the quality of life. Recent technology using high-frequency, low-power ultrasound, or mechanical thrombectomy with catheter-directed delivery of a thrombolytic drug directly into the clot is available and showing promise. Nurses are caring for patients who receive endovascular interventions with lytic infusions. The nursing challenge is to provide safe and effective patient care.

Curcumin and Diabetes: A Systematic Review

2013-01-01

Turmeric (Curcuma longa), a rhizomatous herbaceous perennial plant of the ginger family, has been used for the treatment of diabetes in Ayurvedic and traditional Chinese medicine. The active component of turmeric, curcumin, has caught attention as a potential treatment for diabetes and its complications primarily because it is a relatively safe and inexpensive drug that reduces glycemia and hyperlipidemia in rodent models of diabetes. Here, we review the recent literature on the applications of curcumin for glycemia and diabetes-related liver disorders, adipocyte dysfunction, neuropathy, nephropathy, vascular diseases, pancreatic disorders, and other complications, and we also discuss its antioxidant and anti-inflammatory properties. The applications of additional curcuminoid compounds for diabetes prevention and treatment are also included in this paper. Finally, we mention the approaches that are currently being sought to generate a “super curcumin” through improvement of the bioavailability to bring this promising natural product to the forefront of diabetes therapeutics.

Severe gestational hypertriglyceridemia: A practical approach for clinicians

PubMed Central

Wong, Bertha; Ooi, Teik C

2015-01-01

Severe gestational hypertriglyceridemia is a potentially life threatening and complex condition to manage, requiring attention to a delicate balance between maternal and fetal needs. During pregnancy, significant alterations to lipid homeostasis occur to ensure transfer of nutrients to the fetus. In women with an underlying genetic predisposition or a secondary exacerbating factor, severe gestational hypertriglyceridemia can arise, leading to devastating complications, including acute pancreatitis. Multidisciplinary care, implementation of a low-fat diet with nutritional support, and institution of a hierarchical therapeutic approach are all crucial to reduce maternal and fetal morbidity. To avoid maternal pancreatitis, close surveillance of triglycerides throughout pregnancy with elective hospitalization for refractory cases is recommended. Careful dietary planning is required to prevent neural and retinal complications from fetal essential fatty acid deficiency. Questions remain about the safety of fibrates and plasmapheresis in pregnancy as well as the optimal timing for induction and delivery of these women. PMID:27512474

Mucormycosis is a potentially fatal complication of diabetes. The rhino-orbito-cerebral form is the most common presentation, however, rarely other types can also be seen. We describe the case of a 4½ -year-old boy not previously known to be a diabetic who presented to the plastic surgery department for gangrene of the left middle finger with surrounding erythema and induration. After the diagnosis of diabetes and initial treatment, pus from the wound showed broad aseptate hyphae suggestive of mucormycosis which was further confirmed on culture. Aggressive surgical debridement including amputation, antifungal treatment and glycemic control achieved a complete cure. Cutaneous mucormycosis is a rare complication of type 1 diabetes mellitus and can even be seen at the onset of diabetes. High index of suspicion, timely antifungal treatment and aggressive surgical debridement usually lead to recovery in the localized form of the disease.

Transient osteoporosis of pregnancy.

2012-08-01

Transient osteoporosis of pregnancy (TOP) is a rare yet perhaps under-reported condition that has affected otherwise healthy pregnancies throughout the world. The condition presents suddenly in the third trimester of a usually uneventful pregnancy and progressively immobilizes the mother. Radiographic studies detect drastic loss of bone mass, elevated rates of turnover in the bone, and oedema in the affected portion. Weakness of the bone can lead to fractures during delivery and other complications for the mother. Then, within weeks of labour, symptoms and radiological findings resolve. Aetiology is currently unknown, although neural, vascular, haematological, endocrine, nutrient-deficiency, and other etiologies have been proposed. Several treatments have also been explored, including simple bed rest, steroids, bisphosphonates, calcitonin, induced termination of pregnancy, and surgical intervention. The orthopedist plays an essential role in monitoring the condition (and potential complications) as well as ensuring satisfactory outcomes for both the mother and newborn.

2013-01-01

An estimated 34 million men, women, and children are infected with human immunodeficiency virus type 1 (HIV-1), the virus that causes acquired immunodeficiency syndrome (AIDS). Current technology cannot eradicate HIV-1, and most patients with HIV-1-infection (HIV+) will require lifelong treatment with combined antiretroviral therapy (cART). Stroke was recognized as a complication of HIV-1 infection since the early days of the epidemic. Potential causes of stroke in HIV-1 include opportunistic infections, tumors, atherosclerosis, diabetes, hypertension, autoimmunity, coagulopathies, cardiovascular disease, and direct HIV-1 infection of the arterial wall. Ischemic stroke has emerged as a particularly significant neurological complication of HIV-1 and its treatment due to the aging of the HIV+ population, chronic HIV-1 infection, inflammation, and prolonged exposure to cART. New prevention and treatment strategies tailored to the needs of the HIV+ population are needed to address this issue. PMID:23556125

Complications associated with cervical endoscopic discectomy with the holmium laser.

Haufe, Scott M W; Mork, Anthony R

2004-02-01

Our aim was to determine the rate of surgical complications associated with cervical endoscopic discectomy (CED). There are no studies that state the degree of complications after CED. Forty-one patients underwent CED with holmium laser. Two out of 41 patients incurred vascular compromise during the procedure. One patient developed recurrent laryngeal nerve damage. One patient developed discitis, and two patients complained of a "clicking" sensation postoperatively. Although CED has a relatively high success rate, there is a 15% rate of complications associated with the procedure. Most of the complications were minor (such as vascular compromise, recurrent laryngeal nerve injury, and postoperative "clicking" sensations), but there was one case of severe discitis, and there is the potential of serious complication from both vascular compromise and neural injury.

2017-07-01

Regular physical activity is an important component in the management of both type 1 and type 2 diabetes mellitus (T1DM and T2DM), as it has the potential to improve glycemic control, delay cardiovascular complications, and increase overall well-being. Unfortunately, many children and adolescents with diabetes do not partake in regular exercise and physical activity for multiple reasons. This review identifies the barriers to participation from the aspect of the patient, caregiver, and the healthcare provider. The management of physical activity of children and adolescents with diabetes mellitus is unique and requires an understanding of exercise physiology and how it differs in these children and adolescents from those without the condition. These individuals are at risk for important and potentially life threatening complications including, but not limited to, severe or delayed nocturnal hypoglycemia. It is essential to identify these risks as well as, monitor and manage adjustments to carbohydrate intake and insulin dosing through basal-bolus regimen or insulin pump adjustments appropriately before, during, and after the exercise activity. This review discusses these issues and also outlines differences in management between patients with T1DM and T2DM.

2013-07-01

CKD and its complications are associated with substantial morbidity and mortality. Studies have highlighted significant deficiencies in resident knowledge and awareness of CKD and its complications. There is a need to improve CKD education through medical school and residency. There is also a need to provide alternatives to traditional teaching methods to meet the challenges of learning in the context of work-hour restrictions and increasing workload among residents and fellows. Internet-based learning resources offer various educational tools, including websites, kidney blogs, online modules, and smartphone applications, which could potentially and efficiently advance CKD knowledge among medical trainees. In this review, we describe several online resources for CKD education that could be useful for medical students, residents, and fellows. Increased awareness of these tools and their utilization may significantly influence and hopefully improve the recognition and management of patients with CKD. Future studies may help evaluate the effectiveness of these online learning methods and their effect on CKD patient outcomes. In addition, in light of increased concern about nephrology workforce issues, the potential for these online tools to augment interest in nephrology careers should be investigated.

2018-05-01

The prevalent and long-neglected diabetic foot ulcer (DFU) and its related complications rank among the most debilitating and costly sequelae of diabetes. With the rise of the Internet of medical things (IoMT), along with smart devices, the med-tech industry is on the cusp of a home-care revolution, which could also create opportunity for developing effective solutions with significant potential to reduce DFU-associated costs and saving limbs. This article discusses potential applications of IoMT to the DFU patient population and beyond. To better understand potential opportunities and challenges associated with implementing IoMT for management of DFU, the authors reviewed recent relevant literatures and included their own expert opinions from a multidisciplinary point of view including podiatry, engineering, and data security. The IoMT has opened digital transformation of home-based diabetic foot care, as it enables promoting patient engagement, personalized care and smart management of chronic and noncommunicable diseases through individual data-driven treatment regimens, telecommunication, data mining, and comprehensive feedback tailored to individual requirements. In particular, with recent advances in voice-activated commands technology and its integration as a part of IoMT, new opportunities have emerged to improve the patient's central role and responsibility in enabling an optimized health care ecosystem. The IoMT has opened new opportunities in health care from remote monitoring to smart sensors and medical device integration. While it is at its early stage of development, ultimately we envisage a connected home that, using voice-controlled technology and Bluetooth-radio-connected add-ons, may augment much of what home health does today.

Hysteroscopic Removal of Retained Products of Conception Implanted Over a Focal Area of Adenomyosis: A Case Report.

PubMed

Alonso, Luis; Nieto, Laura; Carugno, Jose

To describe a technique for hysteroscopic removal of retained products of conception (RPOC) implanted over an area of adenomyosis. A case report (Canadian Task Force classification III). RPOC is an unfortunate complication that may occur after the resolution of a normal pregnancy; it is more common after early pregnancy termination or spontaneous miscarriage [1]. Immediate consequences of RPOC include persistent vaginal bleeding, abdominal pain, pelvic infection, fever, and dilated cervix. Moreover, known long-term complications include the formation of intrauterine adhesions (IUAs) with the potential creation of Asherman syndrome resulting in adverse reproductive outcomes caused by subfertility, chronic pelvic pain, menstrual disturbances, and severe pregnancy complications such as abnormal placentation including the placenta accreta spectrum [2,3]. A recently published American Association of Gynecologic Laparoscopists practice report on IUAs suggests that the surgical approach used to treat intrauterine pathology could have an impact with greater risk for IUA formation when blind versus procedures under direct visualization are performed [4]. A 35-year-old patient who presented with persistent bleeding for over 5 weeks. The patient has a long history of dysmenorrhea and heavy menstrual bleeding. Magnetic resonance imaging revealed the presence of adenomyosis. She had an unfortunate spontaneous abortion at 8 weeks of gestation. On physical examination, she was found to have a dilated uterine cervix with persistent vaginal bleeding; there were no signs of infection. Pelvic ultrasound revealed an intrauterine hyperechogenic vascularized area of 2 × 2, 8 × 2 cm implanted over a focal area of adenomyosis, which is consistent with the presence of RPOC. With the aim of minimizing possible acute complications such as bleeding, infection, and uterine perforation, a hysteroscopic approach was taken to avoid performing a blind dilation and curettage. A secondary benefit of a hysteroscopic approach is a lower incidence of long-term complications such as IUAs and the consequent Asherman syndrome. We describe a hysteroscopic technique in which the use of electrosurgery is limited to minimize thermal damage of the endometrium, highlighting important tips and tricks of the procedure. Hysteroscopic removal of RPOC is a feasible and safe management option of this complication of pregnancy. We strongly suggest avoiding performing blind procedures such as dilation and curettage and favor the adoption of this modality that allows the removal of retained products of conception under direct visualization.
