    Congenital pseudoarthrosis is a pathologic entity that may be isolated, or may be associated with neurofibromatosis. We report the case of a 3-year-old female with congenital pseudoarthrosis involving the right tibia and fibula. Magnetic resonance imaging (MRI) and complementary magnetic resonance angiogram (MRA) revealed a lobulated mass with vivid enhancement, which led to the diagnosis of venous malformation. This is the first report of congenital pseudoarthrosis caused by the presence of a vascular malformation. (orig.)

    Pseudoarthrosis is a known complication following lumbar fusion, and although several risk factors have been established, the association of durotomy and pseudoarthrosis has not been studied to our knowledge. A retrospective review was performed to identify all adult patients who underwent lumbar posterolateral fusion (without interbody fusion) for degenerative spine disease over a 20 year period at a single institution. Patients were divided into durotomy and no durotomy cohorts. Patients were included if they had at least 1 year of follow-up. The main outcome variable was development of pseudoarthrosis. A total of 327 patients were identified, of whom 17 (5.19%) had a durotomy. Pseudoarthrosis rates were significantly higher in the durotomy group (35.29%) when compared to the no durotomy group (13.87%), with the difference being statistically significant (p=0.016). Univariate analysis revealed that durotomy (p=0.003) and the number of levels fused (p=0.015) were the only two significant risk factors for pseudoarthrosis. After controlling for the number of levels fused, the adjusted relative risk (RR) revealed that patients with a durotomy were 2.23 times more likely to develop pseudoarthrosis (RR 2.23; 95% confidence interval 1.05-4.75) when compared to patients without durotomy. The findings in the present study suggest an association between durotomy and pseudoarthrosis development. Patients with a durotomy were 2.2 times more likely to develop pseudoarthrosis compared to patients without a durotomy. Future and larger studies are required to corroborate our findings.

    Full Text Available Pseudoarthrosis involving lamina of C2 vertebra requiring intervention is very rare. We report the unusual case of a 38-year-old man presenting with pseudoarthrosis of an old fracture involving left lamina of C2 vertebra. The patient presented with progressive spastic quadriparesis and history of sustaining injury to his neck 15 years ago. Imaging showed pseudoarthrosis involving the left lamina of C2 vertebra with significant cord compression. Posterior approach was used and decompressive laminectomy was done at C2 and C3 levels with removal of the affected segment with pseudoarthrosis. The postoperative period was uneventful and the neurological recovery was good.

  6. Pathogenicity of aseptic Bursaphelenchus xylophilus.

    Directory of Open Access Journals (Sweden)

    Full Text Available Pine wilt is a disease of pine (Pinus spp. caused by the pine wood nematode (PWN, Bursaphelenchus xylophilus. However, the pathogenic mechanism of pine wilt disease (PWD remains unclear. Although the PWN was thought to be the only pathogenic agent associated with this disease, a potential role for bacterial symbionts in the disease process was recently proposed. Studies have indicated that aseptic PWNs do not cause PWD in aseptic pine trees, while PWNs associated with bacteria cause wilting symptoms. To investigate the pathogenicity of the PWN and its associated bacteria, 3-month-old microcuttings derived from certain clones of Pinus densiflora Siebold & Zucc. produced in vitro were inoculated under aseptic conditions with aseptic PWNs, non-aseptic PWNs and bacteria isolated from the nematodes. Six-month-old aseptic P. densiflora microcuttings and 7-month-old P. massoniana seedlings were also inoculated under aseptic conditions with aseptic PWNs and non-aseptic PWNs. The results showed that the aseptic microcuttings and seedlings inoculated with aseptic PWNs or non-aseptic PWNs wilted, while those inoculated with bacterial isolates did not wilt. Nematodes were recovered from wilted microcuttings and seedlings inoculated with aseptic PWNs and non-aseptic PWNs, and the asepsis of nematodes recovered from aseptic PWN-inoculated microcuttings and seedlings was reconfirmed by culturing them in NB liquid medium at 30°C for more than 7 days. Taken together, the results indicate that the asepsis of PWN did not cause the loss of pathogenicity.

    To evaluate the incidence of sternal fracture due to trauma, the CT features of sternal fractures, and the hospitalization period. The medical records and CT images of 755 patients who suffered trauma from January 2012 to August 2013 were analyzed retrospectively. We compared the incidence of sternal fracture due to various traumatic causes. We evaluated the location and shape of the sternal fracture on CT scans and the relationship between a sternal fracture and the hospitalization period. The incidence of sternal fracture was 9.27% (70/755) in all patients; 11.7% (53/453) due to a traffic accident (TA), and 5.63% (17/302) due to other causes. TA was the most frequent cause (75.71%) of a sternal fracture, fracture incidences after a TA differed by traumatic cause (p < 0.05). Among sternal fractures, the body was the most commonly involved (68.57%), one wall was limited (32.85%), and anteroposterior length increased (7.14%). Body fractures involving two or more segments included 33.33% of the cases. The hospitalization period was not related with sternal fracture (p = 0.30). Fracture was more frequent after a TA than due to other causes. Fracture incidences after a TA depended on the traumatic causes. Involvement of two or more segments and one wall-limitation were common among sternal fractures. Sternal fractures occurred even in slightly injured patients.

    The objective of this study was to characterize the different causes of prolonged sternal pain following thoracic trauma with involvement of the sternum and to define criteria for sternal nonunion diagnosis using MRI. Five patients with abnormalities of the sternum were evaluated for prolonged sternal pain following thoracic trauma using MRI. MR images were evaluated by two radiologists in consensus. The patients were selected from the radiology database, which included 8 patients with post-traumatic prolonged sternal pain. Two patients (n = 2) revealed a sternal nonunion after sternal fracture. One patient had a sternal fracture with delayed union and minor displacement of the sternal halves. Abnormal signal intensity alterations adjacent to and within the manubrio-sternal joint were evident in 2 patients and considered due to trauma-related changes in the manubrio-sternal joint. The 3 patients who were not included in the study had no abnormalities of the sternum: 1 of them proved to have a well-healed sternal fracture and nonunion of a rib fracture, 1 had subtle Tietze's syndrome, and 1 patient revealed no pathological findings on imaging. Various factors may be responsible for prolonged sternal pain following thoracic trauma, and these can be viewed with MRI. In cases of sternal nonunion there was common fluid-like signal in the fracture interspace between the bony edges, and the bone marrow adjacent to the nonunion showed altered signal intensity. MRI identified sternal nonunion and other trauma-related abnormalities of the sternum following chest trauma. (orig.)

    Within the next decade, the United States will launch a space station into low Earth orbit as a preliminary step toward a manned mission to Mars. Provision of asepsis in the unique microgravity environment, essential in operative and invasive procedures, is addressed. An assessment of conventional terrestrial aseptic methods and possible modifications for a microgravity environment was done during the microgravity portion of parabolic flight on NASA KC-135 aircraft. During 110 parabolas on three flight days, a "surgical team" (surgeon, scrub nurse and circulating nurse) using a life size mannequin fastened to a prototype surgical "work station" (operating table), evaluated open and closed gloving (ten parabolas), skin preparation (six parabolas), surgical scrub methods (24 parabolas), gowning (22 parabolas) and draping (48 parabolas). Evaluated were povidone iodine solution, 1 percent povidone iodine detergent, Chloroxylenol with detergent, wet prep soap sponge, a water insoluble iodophor polymer (DuraPrep, 3M), disposable towels, disposable and reusable gowns, large and small disposable drapes with and without adhesive edges, disposable latex surgeon's gloves with and without packaging modifications and restraint mechanisms (tether, swiss seat, waist and foot restraint devices, fairfield and wire clamps and clips). Ease of use, provision of restraint for supplies and personnel and waste disposal were assessed. The literature was reviewed and its relevance to the space environment discussed, including risk factors, environmental contamination, immune status and microbiology. The microgravity environment, limited water supply and restricted operating area mandated that modifications of fabrication and packaging of supplies and technique be made to create and preserve asepsis. Material must meet stringent flammability and off-gassing standards. Either a chlorhexidine or povidone iodine detergent prepackaged brush and sponge would provide an adequate scrub plus

    This unit describes some of the ways that a laboratory can deal with the constant threat of microbial contamination in cell cultures. A protocol on aseptic technique is described first. This catch-all term universally appears in any set of instructions pertaining to procedures in which noncontaminating conditions must be maintained. In reality, aseptic technique encompasses all aspects of environmental control, personal hygiene, equipment and media sterilization, and associated quality control procedures needed to ensure that a procedure is, indeed, performed with aseptic, noncontaminating technique. Although cell culture can theoretically be carried out on an open bench in a low-traffic area, most cell culture work is carried out using a horizontal laminar-flow clean bench or a vertical laminar-flow biosafety cabinet. Both are described here. PMID:18228291

    Total hip arthroplasty is one of the most commonly performed and successful elective orthopaedic procedures. However, numerous failure mechanisms limit the long-term success including aseptic osteolysis, aseptic loosening, infection, and implant instability. Aseptic osteolysis and subsequent implant failure occur because of a chronic inflammatory response to implant-derived wear particles. To reduce particulate debris and their consequences, implants have had numerous design modifications including high-molecular-weight polyethylene sockets and noncemented implants that rely on bone ingrowth for fixation. Surgical techniques have improved cementation with the use of medullary plugs, cement guns, lavage of the canal, pressurization, centralization of the stem, and reduction in cement porosity. Despite these advances, aseptic osteolysis continues to limit implant longevity. Numerous proinflammatory cytokines, such as interleukin-1, interleukin-6, tumor necrosis factor-alpha, and prostaglandin E2, have proosteoclastogenic effects in response to implant-derived wear particles. However, none of these cytokines represents a final common pathway for the process of particle-induced osteoclast differentiation and maturation. Recent work has identified the fundamental role of the RANKL-RANK-NF-kappaB pathway not only in osteoclastogenesis but also in the development and function the immune system. Thus, the immune system and skeletal homeostasis may be linked in the process of osteoclastogenesis and osteolysis. PMID:17620815

    Meningitis and myelitis represent common and very infrequent viral infections of the central nervous system, respectively. The number of cases of viral meningitis that occurs annually exceeds the total number of meningitis cases caused by all other etiologies combined. Focal central nervous system infections, such as occur in the spinal cord with viral myelitis, are much less common and may be confused with noninfectious disorders that cause acute flaccid paralysis. This article reviews some of the important clinical features, epidemiology, diagnostic approaches, and management strategies for patients with aseptic meningitis and viral myelitis. Particular focus is placed on the diseases caused by enteroviruses, which as a group account for most aseptic meningitis cases and many focal infections of the spinal cord.

    Full Text Available Pseudoarthrosis is a condition where union at fracture site is very difficult to obtain. But sticking to the very basic principles of management of non-union – that is freshening at fracture site, removal of sclerotic bone, reaming of medullary canal, rigid fixation and abundant bone grafting-helps in achieving the goal. In the below case, all the steps were carried out and the fracture has healed two months postoperatively.

    Full Text Available Radi Shahien1, Vetaly Vieksler1, Abdalla Bowirrat11Department of Neurology and Neurophysiology, Ziv Medical Center, Safed, IsraelAbstract: Meningitis is usually produced by an infectious agent, but there are multiple noninfectious causes. Drug-induced aseptic meningitis (DIAM is an important entity and has been reported as an uncommon adverse reaction with numerous agents. Thus, DIAM constitutes a diagnostic and patient management challenge. We present a patient with three episodes of aseptic meningitis due to amoxicillin, and then review the literature on this rare idiosyncratic event which may occur after local or systemic drug administration. A 77-year-old man was admitted to our hospital with fever, headache, and neck stiffness. Seven days before admission he had a dental and gingival inflammation. He was treated with two oral doses of 500 mg daily of amoxicillin for one week. The seventh day he awoke with the complaints that prompted hospital admittance. Amoxicillin was stopped 1 day before his admission. From his history we knew of two similar episodes: The first episode was after a dental procedure 3 months before this incident. He had received a 1-week course of postprocedure amoxicillin of 500 mg daily and had similar headache, fever, and chills during the entire course of treatment. He wasn’t admitted to the hospital, because he stopped taking amoxicillin and he felt spontaneous pain relief after taking symptomatic pain treatment. The second episodes was 6 months after his first admission, he had been admitted to our hospital with the same symptoms. Amoxicillin was stopped and changed with intravenous (IV ceftriaxone (CTRX for 10 days due to suspected partial untreated meningitis. The patient improved rapidly within 2 days and was discharged from the hospital. On the basis of these three confirmed episodes of meningitis after recurrent exposure to amoxicillin, with repetitive negative testing for viral, bacterial, and mycobacterial

    The bilateral transverse thoracosternotomy clamshell incision provides excellent exposure to the mediastinal structures in double lung transplantation. The use of a modified transverse sternotomy and a figure of 8 configuration with one monofilament metal wire, along with two longitudinal wires across the sternal division, results in greater stability and equally distributed oblique tension. Our described technique was more cost effective and resulted in no incidence of dehiscence. We present our experience using a modified transverse sternotomy and reinforced sternal closure method.

    Full Text Available Introduction: Sternal dehiscence, sternal wound infection and mediastinitis are troublesome complications following median sternotomy which are major causes of morbidity and mortality of patients. Synthetic polydioxanone absorbable suture seems effective in prevention of these complications in children undergoing open heart surgery.Methods: During 2 years period, 620 patients who underwent median sternotomy were studied. The efficacy of absorbable polydioxanone suture was tested on patients using figure-of-eight suture technique. The patients’ age ranged from newborn to 15 years old. All surgical interventions were performed according to a standard protocol.Results: No sternal sutures were broken during the sternal closure and no case of mediastinitis was seen. Two patients experienced sternal dehiscence (0.32%. Follow-up period of patients were established between 1 to 132 months after open heart surgery.Conclusion: Sternal closure with the polydioxanone suture in combination with figure-of-eight technique is a safe and suitable method in children with good clinical results.

    Purpose: to evaluate whether scintigraphy with technetium-99m-labeled ceftizoxime ({sup 99m}Tc-CFT) can differentiate mediastinitis from aseptic inflammation associated with sternotomy. Methods: twenty female Wistar rats were randomly distributed into four groups: S (control) -partial upper median sternotomy with no treatment; SW (control) - sternotomy and treatment of sternal wounds with bone wax; SB - sternotomy and infection with Staphylococcus aureus; SWB - sternotomy with bone wax treatment and bacterial infection. Scintigraphy with {sup 99m}Tc-CFT was performed eight days after surgery and images were collected 210 and 360 min after infusion of the radiopharmaceutical. Results: no animals exhibited clinical signs of wound infection at the end of the experiment, although histological data verified acute inflammatory response in those experimentally infected with bacteria. Scintigraphic images revealed that tropism of {sup 99m}Tc-CFT to infected sternums was greater than to their non-infected counterparts. Mean counts of radioactivity in bacteria-infected sternal regions (SB and SWB) were significantly higher (p = 0.0007) than those of the respective controls (S and SW).Conclusion: scintigraphy with technetium-99m-labeled ceftizoxime is a method that can potentially detect infection post sternotomy and differentiate from aseptic inflammation in animals experimentally inoculated with S. aureus (author)

  12. Sternal fractures as a manifestation of abusive injury in children

    International Nuclear Information System (INIS)

    Sternal fractures are rare injuries in children. The rarity of this injury is likely due to both the relative plasticity of the pediatric thorax and to the difficulty in establishing a radiographic diagnosis without dedicated views. Current literature suggests that this injury in young children is highly specific for abusive injury.Hypothesis. Sternal fractures are not highly specific for abusive injury. Materials and methods. This was a retrospective radiographic and clinical chart review of all documented sternal fractures over an 11-year period at a large pediatric hospital.Results. Of 12 children with sternal fractures identified, four were ≤2 years of age and eight were ≥3 years of age. The mechanism of injury was suspicious for child abuse in two children. Both of these children were ≤2 years of age. In one toddler, an unwitnessed injury resulted in extensive initial familial anxiety until abusive injury was excluded.Conclusion. Sternal fractures are unusual injuries, yet they, in themselves, are not highly specific for abusive injury. (orig.)

    Sternal fractures are rare injuries in children. The rarity of this injury is likely due to both the relative plasticity of the pediatric thorax and to the difficulty in establishing a radiographic diagnosis without dedicated views. Current literature suggests that this injury in young children is highly specific for abusive injury.Hypothesis. Sternal fractures are not highly specific for abusive injury. Materials and methods. This was a retrospective radiographic and clinical chart review of all documented sternal fractures over an 11-year period at a large pediatric hospital.Results. Of 12 children with sternal fractures identified, four were {<=}2 years of age and eight were {>=}3 years of age. The mechanism of injury was suspicious for child abuse in two children. Both of these children were {<=}2 years of age. In one toddler, an unwitnessed injury resulted in extensive initial familial anxiety until abusive injury was excluded.Conclusion. Sternal fractures are unusual injuries, yet they, in themselves, are not highly specific for abusive injury. (orig.)

    Full Text Available Congenital sternal foramen is an anomaly whose occurrence is rare in human but is especially unusual in animals. This defect was formed when fusion of multiple ossification centers was incomplete. It may be associated with other lesions in body organs especially cardiac anomalies. In the present study, we report a very rare case of congenital sternal foramen in a Holstein calf. The oval defect was like a gunshot wound and located at the lower third of the sternum. Apparently, the rest of skeleton system seems normal. The awareness of the anomaly is important for better diagnosis and treatment of diseases.

    Presented here is the case of a nine-month-old boy with the osteomyelitis of the upper area sternum caused by bacillus Calmette-Guerin (BCG), the Danish 1331 strain vaccine against tuberculosis. Upon examination, a swelling of approximately 2×3 cm diameter was observed in the upper sternal area. The mass was hard, fixed and sensitive to palpation with no local skin hyperaemia. Chest X-rays revealed a round mass anterior to the sternum, suggesting a diagnosis of osteomyelitis. A consequent sternal biopsy was performed and Mycobacterium bovis BCG was identified by a positive growth culture. PMID:27777704

    CT scans of the patients with aseptic and bacterial meningitis were reviewed and compared to previous reports. In aseptic meningitis, no abnormal CT findings were observed. In bacterial meningitis, CT findings were ventricular dilatation, subdural fluid collection, parenchymal low density, intracerebral hematoma and meningeal enhancement after contrast injection. Three patients among 48 suffered from status epileptics during the course of the illness. All of the 3 patients developed parenchymal inhomogeneous low density and progressive ventricular dilatation which did not improve after ventricular peritoneal shunt surgery. We believe that these changes are most likely due to hypoxic hypoxemia during epileptic seizure and meningitis itself seems to play a little role.

    Background Median sternotomy is considered the most usually performed procedure in cardiac operations. This study aimed to assess clinical effectiveness of bilateral pectoralis major muscle flaps (BPMMF) for management of sternal osteomyelitis and mediastinal infection following median sternotomy.Methods Clinical data were collected and retrospectively analyzed from twelve patients who underwent the BPMMF transposition for management of sternal osteomyelitis and mediastinal infection following median sternotomy from January 2006 to June 2009. Procedure consisted of rigorous debridement of necrotic tissues, dead space obliteration using the BPMMF, and placement of drainage tubes connected to a negative pressures generator for adequate drainage.Results No patients died of drainage, and all 12 patients had viable BPMMF when discharged from hospital. At 1 week post discharge, 2 patients presented with sternal infection but recovered following local debridement and medication. No patients showed infection recurrence during the follow-up period over 10 months.Conclusions Sternal osteomyelitis and mediastinal infection following median sternotomy may be effectively managed through rigorous debridement of infected soft tissues, resection of the damaged stermal segment, transposition of the BPMMF to fill the damaged sternum resulting from debridement, and adequate postoperative drainage.

    In cardiac surgery, sternal wound infection (SWI) continues to be one of the most serious postoperative complications. Coagulase-negative staphylococci (CoNS) have become the most common causative agents of SWI. Prophylaxis with intravenous beta-lactam antibiotics (cephalosporins or in Sweden most commonly isoxazolyl penicillins) is routinely practised. However, many CoNS species are resistant to beta-lactam antibiotics. Vancomycin is often the only effective antibiotic available for treatmen...

    2014-01-01

    Full Text Available Introduction: We report a case of a young female soccer player affected by congenital medial bilateral malleolus pseudoarthrosis and os subfibulare. Congenital pseudoarthrosis is the failure of the bones to fuse prior or at birth. The etiology is still unknown, although frequency is high in subjects affected by neurofibromatosis or correlated syndromes, so it has been suggested that these congenital disorders may be the cause of congenital pseudoarthrosis. Case Report: Our patient, a 16-year-old female, high level soccer player, was referred to us following a right ankle sprain during a match. She reported no medical history of tibia-tarsus joint injuries or disease. Pain, swelling and functional impairment were noted immediately after the accident. Standard radiographs in the emergency department revealed a displaced fracture of the medial malleolus and the presence of os subfibularis. The patient was transferred to our Traumatology and Orthopaedic Department to undergo malleolus ostheosynthesis. Before surgery swelling, functional impairment and intense pain at the medial malleolus level were confirmed. However, there was no radiological opening of ankle, instability or pronation pain; furthermore the flexion-extension was preserved with slight pain. Twenty-four hours later a considerable remission of symptoms was evident with increased range of motion and reduction in the swelling and post-traumatic edema. A radiograph on the left ankle to compare with that of the right ankle was necessary to overcome the discrepancy between the radiological diagnosis and the clinical examination. The radiographic results of both medial malleoli were comparable although on the left the os subfibularis was absent. Since the diagnosis of fracture by the association between the radiographs and the symptomatology was doubtful, a bilateral CT was performed. The scan revealed a medial bilateral malleolus pseudoarthrosis and an accessory right subfibularis nucleus

    We describe the case of a 29-year-old woman with recurrent aseptic meningitis that was caused by ergot agents. She miscarried at age 27, and the uterus constrictor methylergometrine was prescribed. Three days later, she developed aseptic meningitis and was hospitalized. Two years later, she again developed aseptic meningitis the day after she took ergotamine tartrate. In both events, her symptoms improved rapidly when the medication was stopped. The drug-induced lymphocyte stimulation test for methylergometrine yielded a value of 180%. Drug-induced meningitis is a rare form of recurrent aseptic meningitis. Many studies have reported cases of meningitis caused by non-steroidal anti-inflammatory drugs, but many other drugs can induce aseptic meningitis. To the best of our knowledge, this is the first case of aseptic meningitis induced by ergot agents. PMID:26103816

    We aimed to show the utility and reliability of sternal morphometric analysis for sex estimation.Sex estimation is a very important step in forensic identification. Skeletal surveys are main methods for sex estimation studies. Morphometric analysis of sternum may provide high accuracy rated data in sex discrimination. In this study, morphometric analysis of sternum was evaluated in 1 mm chest computed tomography scans for sex estimation. Four hundred forty 3 subjects (202 female, 241 male, mean age: 44 ± 8.1 [distribution: 30-60 year old]) were included the study. Manubrium length (ML), mesosternum length (2L), Sternebra 1 (S1W), and Sternebra 3 (S3W) width were measured and also sternal index (SI) was calculated. Differences between genders were evaluated by student t-test. Predictive factors of sex were determined by discrimination analysis and receiver operating characteristic (ROC) analysis. Male sternal measurement values are significantly higher than females (P < 0.001) while SI is significantly low in males (P < 0.001). In discrimination analysis, MSL has high accuracy rate with 80.2% in females and 80.9% in males. MSL also has the best sensitivity (75.9%) and specificity (87.6%) values. Accuracy rates were above 80% in 3 stepwise discrimination analysis for both sexes. Stepwise 1 (ML, MSL, S1W, S3W) has the highest accuracy rate in stepwise discrimination analysis with 86.1% in females and 83.8% in males. Our study showed that morphometric computed tomography analysis of sternum might provide important information for sex estimation. PMID:25501090

    Full Text Available Scedosporium is an important pathogen in cystic fibrosis (CF and post-transplant but rarely causes invasive infection. Treatment remains challenging, particularly due to inherent resistance to multiple antifungal agents. We present a young man with CF who developed invasive sternal and rib infection 10-months following lung transplant. The infection has been clinically and radiologically cured with extensive surgery and triazole therapy. This case highlights the importance of adjunctive surgery in addition to prolonged triazole treatment to manage invasive Scedosporium infections in immunosuppressed patients.

    Skeletal abnormalities such as hypertrophic callus formation and ''popcorn'' calcifications are rare radiological findings of osteogenesis imperfecta, causing tumor-like appearances on imaging. We report on a 7-year-old girl with osteogenesis imperfecta presenting with hepatomegaly and palpable lymphadenopathy in the left inguinal region on physical examination. Computed tomography examination revealed a high-density mass-like lesion of the manubrium sterni. Ultrasonography and a lateral roentgenogram of the chest verified that this was a pseudomass caused by a bowed sternal manubrium. (orig.)

    The median sternotomy for cardiac operations can be reapproximated in a variety of ways. Traditionally, sternal wires have been used in several configurations to afford satisfactory closure. Alternative techniques include cables, plates, and clip-like devices. A relatively recent addition to the menu of options is the plastic tie band. Although a few studies have suggested its efficacy, this favorable experience has not been universal. The purpose of this report is to describe a failure in closure and the reaction of the soft tissue around it. PMID:27449444

    1983-11-01

    Methods used by industry with applications to hospital pharmacy for maintaining an aseptic environment in production of sterile pharmaceutical products are discussed. A major source of product contamination is airborne microorganisms. The laminar-airflow workbench with a high-efficiency particulate air filter provides an ultraclean environment for preparation of sterile products. However, the workbench does not guarantee sterility of products and is not effective if not properly installed and maintained or if the operator uses poor aseptic technique. The laminar-airflow workbench should be tested for leaks, airflow velocity, and airflow patterns when installed, and the workbench should be checked periodically thereafter. The workbench should be placed in a cleanroom where traffic and air disturbances that might affect the laminar airflow are eliminated. A major source of airborne microbial contamination in cleanrooms is people. Personnel movement through an area and presence of personnel without lint-free, nonshedding protective garments increase the levels of microbial contaminants in an area. The transport of nonsterile products (bottles, boxes, paper products) into a cleanroom should be minimized. The cleanroom itself should be sanitized and should be immaculate. Microbial or particulate monitoring should be conducted in the cleanroom using a quantitative method, and corrective-action limits should be set. Hospital pharmacists should examine industrial sterile-processing techniques and apply them to the preparation of sterile products.

    Full Text Available Background: The implementation of seat belt legislation has led to an increase in the frequency of isolated sternal fractures (ISFs in motor vehicle crash. Aims: We reviewed retrospectively the medical records of our tertiary center in order to find out the frequency of ISFs, review our experience in their management, and define the mean length of hospitalization. Materials and Methods: From January 2008 to April 2012, 64 patients were admitted to the accident and emergency department of the University Hospital of Larissa, Greece, suffering from sternal fractures (SFs. Of these 64 patients, 45 had sustained ISF, while the remaining 19 had SF and additional injuries (intrathoracic and extrathoracic. The files of these 45 patients were further investigating as concerning the mechanism of injury, hospitalization days, morbidity, and mortality. Results: All the patients had been involved in motor vehicle crashes and most of them were wearing seat belts during the accident (91%. The hospital length of stay (LOS was 1.85 ± 1.67. All the patients had upon admission chest radiograms, serial electrocardiographs (ECGs, echocardiograms, and cardiac enzyme levels. Two patients had abnormal ECG and abnormal cardiac enzymes which contributed in prolonged hospitalization. However, there was no incidence of cardiac complications or deaths. Conclusions: ISFs, with normal electrocardiogram, cardiac enzymes, and chest X-ray in the absence of complications, require no further investigation.

    Full Text Available Abstract Sternal dehiscence is a serious complication after cardiac surgery. Sternal refixation, performed by simple rewiring or techniqual modification of rewiring as described by Robicsek, can fail, overall when the bone quality is poor or the sternum is completely destroyed. The sternal closure systems, consisting of plates, screws or rib clips and titanium bars, have been recently introduced to treat the complicated sternal dehiscence. We describe for the first time the use of the Strasbourg Thoracic Osteosyntheses System (STRATOS and the greater omentum, to treat a complicated sternal dehiscence, causing chest pain and respiratory failure.

    Full Text Available Biology educators emphasize aseptic technique when teaching lab courses. Aseptic technique is very important in microbiology to ensure safety and prevent cross-contamination. Although it can be assessed throughout the semester by examining the students’ technique and observation of contamination, this tool offers a simple semester-long graded assessment of each student’s technique. The procedures allow the students to perform a quick exercise that can determine if cross-contamination occurs, thus determining if aseptic technique was observed. Instructors can quickly check for the presence of cross-contamination. After implementing this procedure, a quantifiable improvement in my students’ aseptic technique throughout the semester was observed. It was noted that between the middle and end of the semester there was a slight increase in the amount of cross-contamination but still well below the contamination observed at the beginning of the semester. This procedure was a valuable way to assess aseptic technique during the course of a semester. A search for “aseptic technique” on the American Society of Microbiology website reveals that several lab experiments and job opportunities mention the importance of aseptic technique. It is a skill that must be used for all laboratory procedures when working with microorganisms. It is important for both the safety of the students and for the proper handling of microorganisms. There are several good explanations of aseptic technique on the Internet, and the Nuffield Foundation provides a very good description of techniques (1. The goal of this project is to provide instructors with a tool to assess the aseptic technique of their students by using simple transfers of bacteria to fresh media to identify cross-contamination. When class experiments do not work students may not understand how poor aseptic technique impacted the project. This tool would work best for undergraduate students in an

  17. First evidence of sternal wound biofilm following cardiac surgery.

    Directory of Open Access Journals (Sweden)

    Haytham Elgharably

    Full Text Available Management of deep sternal wound infection (SWI, a serious complication after cardiac surgery with high morbidity and mortality incidence, requires invasive procedures such as, debridement with primary closure or myocutaneous flap reconstruction along with use of broad spectrum antibiotics. The purpose of this clinical series is to investigate the presence of biofilm in patients with deep SWI. A biofilm is a complex microbial community in which bacteria attach to a biological or non-biological surface and are embedded in a self-produced extracellular polymeric substance. Biofilm related infections represent a major clinical challenge due to their resistance to both host immune defenses and standard antimicrobial therapies. Candidates for this clinical series were patients scheduled for a debridement procedure of an infected sternal wound after a cardiac surgery. Six patients with SWI were recruited in the study. All cases had marked dehiscence of all layers of the wound down to the sternum with no signs of healing after receiving broad spectrum antibiotics post-surgery. After consenting patients, tissue and/or extracted stainless steel wires were collected during the debridement procedure. Debrided tissues examined by Gram stain showed large aggregations of Gram positive cocci. Immuno-fluorescent staining of the debrided tissues using a specific antibody against staphylococci demonstrated the presence of thick clumps of staphylococci colonizing the wound bed. Evaluation of tissue samples with scanning electron microscope (SEM imaging showed three-dimensional aggregates of these cocci attached to the wound surface. More interestingly, SEM imaging of the extracted wires showed attachment of cocci aggregations to the wire metal surface. These observations along with the clinical presentation of the patients provide the first evidence that supports the presence of biofilm in such cases. Clinical introduction of the biofilm infection concept in deep

    Tomoyuki Kuwata

    2014-12-01

    Full Text Available We report the case of an 8-month-old male neonate who underwent reconstructive surgery for a congenital superior sternal cleft to decrease the risk of commotio cordis. With regard to use of the Sally technique for the repair of a relatively wide cleft (4 × 4 cm, we were concerned about respiratory problems caused by compression following closure of the sternal halves. By closing the sternal halves imperfectly, elevation of intrapleural pressure can be avoided to some extent. By bridging the surplus resected cartilage from the lower sternum over the gap of the upper sternum, the heart is protected by more rigid material. We recommend our modified Sally technique because it is both flexible and effective for sternal cleft repair.

    2014-01-01

    Objective To assess clinical effectiveness of using bilateral pectoralis major or plus rectus abdominis muscle flaps in treating deep sternal wound infection (DSWI) following median sternotomy. Methods Between January 2009 and December 2013, 19 patients with DSWI after median sternotomy for cardiac surgery were admitted to our hospital, including 14 males (73.7%) and 5 females (26.3%), aged 55±13 (18-78) years. According to the Pairolero classification of infected median sternotomies, 3 (15.8%) patients were type II, and the other 16 (84.2%) were type III. Surgical procedure consisted of adequate debridement of infected sternum, costal cartilage, granulation, steel wires, suture residues and other foreign substances. Sternal reconstruction used the bilateral pectoralis major or plus rectus abdominis muscle flaps to obliterate dead space. The drainage tubes were placed and connected to a negative pressure generator for adequate drainage. Results There were no intraoperative deaths. In 15 patients (78.9%), bilateral pectoral muscle flaps were mobilized sufficiently to cover and stabilize the defect created by wound debridement. 4 patients (21.0%) needed bilateral pectoral muscle flaps plus rectus abdominis muscle flaps because their pectoralis major muscle flaps could not reach the lowest portion of the wound. 2 patients (10.5%) presented with subcutaneous infection, and 3 patients (15.8%) had hematoma. They recovered following local debridement and medication. 17 patients (89.5%) were examined at follow-up 12 months later, all healed and having stable sternum. No patients showed infection recurrence during the follow-up period over 12 months. Conclusion DSWI following median sternotomy may be effectively managed with adequate debridement of infected tissues and reconstruction with bilateral pectoralis major muscle or plus rectus abdominis muscle flap transposition.

    Full Text Available Wear debris-induced aseptic loosening is an inflammatory bone disorder, which compromises the long-term success of total joint replacement. Despite the extensive research and great progress in treating inflammation-induced osteolysis for inflammatory arthritis, no drug has been proven for treatment/prevention of aseptic implant loosening. Also, there is very limited research on developing effective drug delivery systems for this pathological condition. In this review, we will discuss different therapeutic interventions and various delivery systems that have been developed for aseptic implant loosening. To provide the prospective for the future research in this area, the biology of wear particles-induced osteolysis, animal models developed for aseptic implant loosening and the potential challenges the field is facing are also presented in the discussion.

Design Case report and literature review. Results A 65-year-old female patient with a symptomatic craniopharyngioma underwent transsphenoidal resection. She returned postoperatively with symptoms concerning for cerebrospinal fluid (CSF) leak and bacterial meningitis. Lumbar puncture demonstrated mildly elevated leukocytes with normal glucose levels. Cultures were sterile and she was discharged on antibiotics. She returned 18 days postoperatively with altered mental status and fever. Again, negative CSF cultures suggested aseptic meningitis. Radiological and intraoperative findings were now concerning for widespread cerebrovascular vasospasm due to leaked craniopharyngioma fluids. In the following months, her craniopharyngioma recurred and required multiple surgical resections. Days after her last operation, she returned with mental status changes and a sterile CSF culture. She was diagnosed with recurrent aseptic meningitis and antibiotics were discontinued. The patient experienced near complete resolution of symptoms. Conclusions Consideration of aseptic meningitis following craniopharyngioma resection is critical to avoid unnecessary surgical re-exploration and prolonged courses of antibiotics. PMID:27722072

    Despite many advances in prevention and perioperative care, deep sternal wound infection (DSWI) remains a pressing concern in cardiac surgery, with a still relevant incidence and with a considerable impact on in-hospital mortality and also on mid- and long-term survival. The permanent high impact of this complication is partially related to the increasing proportion of patients at high-risk for infection, as well as to the many patient and surgical risk factors involved in the pathogenesis of DSWI. The prophylactic antibiotic therapy is one of the most important tools in the prevention of DSWI. However, the choice of antibiotic, the dose, the duration, the adequate levels in serum and tissue, and the timing of antimicrobial prophylaxis are still controversial. The treatment of DSWI ranges from surgical revision with primary closure to surgical revision with open dressings or closed irrigation, from reconstruction with soft tissue flaps to negative pressure wound therapy (NPWT). However, to date, there have been no accepted recommendations regarding the best management of DSWI. Emerging evidence in the literature has validated the efficacy and safety of NPWT either as a single-line therapy, or as a "bridge" prior to final surgical closure. In conclusion, the careful control of patient and surgical risk factors - when possible, the proper antimicrobial prophylaxis, and the choice of validated techniques of treatment could contribute to keep DSWIs at a minimal rate.

    Full Text Available Cat scratch disease (CSD is a self limited condition characterized by fever, lymph node enlargement and less often eye involvement. Central nervous system involvement by Bartonella henselae infection is possibly an important cause of morbidity; its role as an agent of aseptic meningitis is unknown. We report a case of a 40 years-old man with CSD accompanied by aseptic meningitis and neuroretinitis. Serum indirect immmunofluorescence (IFI assays for B. henselae were positive and the cerebrospinal fluid (CSF analysis showed mononuclear pleocytosis and increased level of protein. Serological tests for other etiologies were negative. The patient responded well to antibiotic therapy with oral doxycicline plus rifampin and in the 12th day of hospitalization evolved to total regression of the headache and partial regression of the visual loss. Clinicians should consider CSD as a differential diagnosis when assessing previously healthy patients with aseptic meningitis associated with regional lymphadenopathy and epidemiological history of feline contact.

    MR studies were performed in three patients with paralysis in the lower extremities. Poliomyelitis-like paralysis can be caused by neurovirulent strains of nonpolioenteroviruses. Entervirus 71 (EV 71) is documented as one of the potentially neurovirulent strains and a causative agent of some epidemics (1-7). The clinical manifestations associated with the EV 71 infection include aseptic meningitis, hand-food-mouth disease (HFMD), acute respiratory illness and gastrointestinal disease(6). Although rarely fatal, flaccidparalysis can be followed by EV 71 induced aseptic meningitis. Anterior horn cell necrosis was suggested on MR in two patients with residual paralysis (7). MR features, however, have not yet been described in detail. In this report we present three cases of patients with clinical evidence of EV 71 induced aseptic meningitis whose MR studies showed residual changes in spinal cord.

    Full Text Available BACKGROUND: Non-polio human enteroviruses are the leading cause of aseptic meningitis in children. The role of enterovirus PCR for diagnosis and management of aseptic meningitis has not been fully explored. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective study was conducted to determine the epidemiological, clinical, and laboratory characteristics of aseptic meningitis and to evaluate the role of enterovirus PCR for the diagnosis and management of this clinical entity. The medical records of children who had as discharge diagnosis aseptic or viral meningitis were reviewed. A total of 506 children, median age 5 years, were identified. The annual incidence rate was estimated to be 17/100,000 children less than 14 years of age. Most of the cases occurred during summer (38% and autumn (24%. The dominant clinical symptoms were fever (98%, headache (94% and vomiting (67%. Neck stiffness was noted in 60%, and irritation in 46% of the patients. The median number of CSF cell count was 201/mm(3 with polymorphonuclear predominance (>50% in 58.3% of the cases. Enterovirus RNA was detected in CSF in 47 of 96 (48.9% children tested. Children with positive enterovirus PCR had shorter hospitalization stay as compared to children who had negative PCR or to children who were not tested (P = 0.01. There were no serious complications or deaths. CONCLUSIONS: Enteroviruses accounted for approximately one half of cases of aseptic meningitis. PCR may reduce the length of hospitalization and plays important role in the diagnosis and management of children with aseptic meningitis.

    Traditional sternal precautions, given to sternotomy patients as part of their discharge education, are intended to help prevent sternal wound complications. They vary widely but generally include arbitrary load and time restrictions (lifting no more than a specified weight for up to 12 weeks) and may prohibit common shoulder joint and shoulder girdle movements. Having observed the negative effects of restrictive sternal precautions for many years, our research team performed a series of studies that measured the forces exerted during various common activities and their relationship to the sternum. The results, though informative, led us to realize that the goal of identifying "the" appropriate load restriction to prescribe for sternotomy patients was futile. The alternative approach that we introduce applies standard kinesiological principles and teaches patients how to perform load-bearing movements in a way that avoids excessive stress to the sternum.

    2016-01-01

    Background The aim of the study was to test the hypothesis that in patients with chronic complex sternum dehiscence, the use of muscle flap repair minimizes the occurrence of paradoxical motion of the chest wall (CWPM) when compared to sternal rewiring, eventually leading to better respiratory function and clinical outcomes during follow-up. Methods In a propensity score matching analysis, out of 94 patients who underwent sternal reconstruction, 20 patients were selected: 10 patients underwent sternal reconstruction with bilateral pectoralis muscle flaps (group 1) and 10 underwent sternal rewiring (group 2). Eligibility criteria included the presence of hemisternum diastases associated with multiple (≥3) bone fractures and radiologic evidence of synchronous chest wall motion (CWSM). We compared radiologically assessed (volumetric computed tomography) ventilatory mechanic indices such as single lung and global vital capacity (VC), diaphragm excursion, synchronous and paradoxical chest wall motion. Results Follow-up was 100% complete (mean 85±24 months). CWPM was inversely correlated with single lung VC (Spearman R=−0.72, p=0.0003), global VC (R=−0.51, p=0.02) and diaphragm excursion (R=−0.80, p=0.0003), whereas it proved directly correlated with dyspnea grade (Spearman R=0.51, p=0.02) and pain (R=0.59, p=0.005). Mean CWPM and single lung VC were both better in group 1, whereas there was no difference in CWSM, diaphragm excursion and global VC. Conclusion Our study suggests that in patients with complex chronic sternal dehiscence, pectoralis muscle flap reconstruction guarantees lower CWPM and greater single-lung VC when compared with sternal rewiring and it is associated with better clinical outcomes with less pain and dyspnea.

    Full Text Available Hodgkin′s lymphoma with sternal involvement at presentation is quite unusual. Owing to its rarity, it often poses vexing diagnostic challenges. We herein bring into focus a case of advanced stage Hodgkin′s lymphoma, presenting with a sternal mass, initially misdiagnosed and treated as Langerhans cell histiocytosis. On subsequent follow-up, the patient developed recurrence and repeat biopsy and imaging suggested Hodgkin′s lymphoma. The case report highlights the importance of clinical suspicion of unusual presentation of lymphohematopoietic tumors of the bone.

    Full Text Available Introduction: Mediastinitis is a devastating complication in open heart surgery. The most common treatments after debridement are rewiring with antibiotic irrigation. Vacuum assisted closure therapy is a recently introduced technique that promotes the healing of difficult wounds, including post-sternotomy mediastinitis.Patients and Methods: Forty one patients with deep sternal wound infection were divided into two groups based on the treatment method used. Twenty two patients with post-cardio to my deep sternal wound infection were treated primarily by vacuum assisted closure method (group A and 19 patients with deep sternal wound infection who received closed mediastinal irrigation were treated with antibiotics (group B between January 2006 and January 2010.Results: The two groups were compared. Three patients died during treatment in group B. The median healing time was significantly shorter in group A (mean, 13.5 ± 3.2 days compared to 18 days (mean, 21.2 ± 16.4 days in group B (p< 0.001. Deep sternal wound infection showed no recurrences after the vacuum treatment, while 7 (24% patients in group B suffered recurrences. Hospital stay was significantly shorter in group A (median, 30.5 days; mean, 32.2 ± 11.3 days vs. median, 45 days; mean, 49.2 ± 19.3 days (p= 0.001.Conclusion: A significantly shorter healing time was confirmed with vacuum assisted closure.

    2016-01-01

    Full Text Available Autologous and nonautologous bone marrow mesenchymal stem/stromal cells (MSCs are being evaluated as proangiogenic agents for ischemic and vascular disease in adults but not in children. A significant number of newborns and infants with critical congenital heart disease who undergo cardiac surgery already have or are at risk of developing conditions related to inadequate tissue perfusion. During neonatal cardiac surgery, a small amount of sternal tissue is usually discarded. Here we demonstrate that MSCs can be isolated from human neonatal sternal tissue using a nonenzymatic explant culture method. Neonatal sternal bone MSCs (sbMSCs were clonogenic, had a surface marker expression profile that was characteristic of bone marrow MSCs, were multipotent, and expressed pluripotency-related genes at low levels. Neonatal sbMSCs also demonstrated in vitro proangiogenic properties. Sternal bone MSCs cooperated with human umbilical vein endothelial cells (HUVECs to form 3D networks and tubes in vitro. Conditioned media from sbMSCs cultured in hypoxia also promoted HUVEC survival and migration. Given the neonatal source, ease of isolation, and proangiogenic properties, sbMSCs may have relevance to therapeutic applications.

    Aseptic meningitis refers to a clinical syndrome of meningeal inflammation in which bacteria cannot be identified in the cerebrospinal fluid (CSF). The viral etiology and the epidemiological, clinical, and laboratory characteristics of aseptic meningitis among children aged 2 months to 15 years in Shiraz, southern Iran were determined. From May 2007 to April 2008, 65 patients were admitted to the hospital with aseptic meningitis. Seven viruses, non-polio human enteroviruses, mumps virus, herpes simplex virus (HSV), varicella-zoster virus (VZV), human cytomegalovirus (HCMV), human herpes virus type 6 (HHV-6), and Epstein-Barr virus (EBV) were investigated by polymerase chain reaction (PCR) method. Viruses were detected in 30 (46.2%) patients in whom non-polio human enterovirus and mumps virus were detected in 13 (43.3%) and 11 (36.7%), respectively. The remaining 6 (20%) of the cases were caused by HSV, VZV, HCMV, and HHV-6. Haemophilus influenzae and non-polio human enterovirus were detected in one patient simultaneously. Viral meningitis was found to be more frequent during spring and summer. The majority (66.6%) of the patients were treated in the hospital for 10 days and had received antibiotics in the case of bacterial meningitis. Rapid diagnosis of viral meningitis using PCR testing of CSF can help shorten hospitalization, and avoid the unnecessary use of antibiotics.

    Aseptic necrosis of the femoral head is a disease whose etiology is not completely elucidated and generally affects young adults aged between 30 and 50 years. In a significant number of patients bilateral disease occurs, which makes detection in its early stages constitute an important objective. We present the case of a male patient, aged 23 years, with the following risk factors: smoking and chronic alcohol consumption, who is diagnosed with aseptic necrosis of the left femoral head, ARCO stage IV, and in just six months after the diagnosis and hip arthroplasty, he suffers an injury which leads to the same diagnosis in the contralateral hip. We want to emphasize that for all patients with a high index of suspicion there should be an MRI examination, because the plane radiographs or CT are most often not relevant in detecting early signs of this condition. Diagnosis of aseptic necrosis of the femoral head in the early stages is a necessity in order to obtain an optimal result of conservative treatment. PMID:26788359

    Full Text Available A 15-year-old boy was referred to our hospital for further investigation and treatment of sternal osteomyelitis due to blunt chest trauma, more specifically elbowing during a basketball game 19 days earlier. On an initial presentation, his chest was markedly swollen and chest computed tomography demonstrated a sternal fracture and massive fluid collection in the chest wall. Since his general condition remained fairly good, we initially selected minimal drainage concomitant with antibiotics; if it was unsuccessful, we planned to switch to a more radical debridement procedure. The patient recovered without further invasive intervention and was discharged on postoperative day 26. There is no sign of recurrence six months after operation. This case report indicates that minimal drainage would be a good option for treatment in a phased strategy.

    A variety of metallic components have been used in medical devices where lifelong durability and physical strength are demanded. To investigate the in vivo changes of implanted metallic medical devices in humans, stainless steel sternal wires removed from patients were evaluated. Stainless steel (316L) sternal wires removed from four patients after 10, 13, 22, and 30 years of implantation were evaluated using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). Macroscopically, the removed specimens maintained their metallic luster and color. Under SEM, small holes were observed sporadically at 10 years and they tended to connect in the drawing direction. The longer the implanted duration, the more numerous and deeper were the crevices observed. By EDS, sulfur, phosphorus, and calcium were identified in all areas at 10 years, in addition to the component elements of stainless steel, comprising iron, chromium, nickel, and manganese. Corrosion products observed at 30 years were identified as calcium phosphate. In conclusion, stainless steel sternal wires develop corroded pores that grow larger and deeper with time after implantation; however, the pores remain shallow even after decades of implantation and they may not be a cause of mechanical failure. An amount of metal ions equivalent to the corroded volume must have been released into the human body, but the effect of these metal ions on the body is not apparent.

    Full Text Available Since 2007, we had started clinical trial using mesenchymal stem cell (MSCs for the treatment of aseptic bone necrosis as a first clinical trial permitted by Japanese Health, Labour and Welfare Ministry.Aseptic bone necrosis of the femoral head commonly occurs in patients with two to four decades, causing severe musculoskeletal disability. Although its diagnosis is easy with X-ray and MRI, there has been no gold standard invented for treatment of this disease. MSCs represent a stem cell population in adult tissues that can be isolated and expanded in culture, and differentiate into cells with different nature. Combination with β-tri-calcium phosphate and vascularized bone graft, we succeeded to treat bone necrosis of the femoral head.Regenerative medicine using stem cells is hopeful and shed a light on intractable disease. To become widespread, Basic, Translational, Application, and Developmental study is needed.? From an experience of cell therapy using MSCs, we started to research induced pluripotent stem cell (iPS for clinical application.

  3. The pathobiology and pathology of aseptic implant failure

    Science.gov (United States)

    2016-01-01

    Pathological assessment of periprosthetic tissues is important, not only for diagnosis, but also for understanding the pathobiology of implant failure. The host response to wear particle deposition in periprosthetic tissues is characterised by cell and tissue injury, and a reparative and inflammatory response in which there is an innate and adaptive immune response to the material components of implant wear. Physical and chemical characteristics of implant wear influence the nature of the response in periprosthetic tissues and account for the development of particular complications that lead to implant failure, such as osteolysis which leads to aseptic loosening, and soft-tissue necrosis/inflammation, which can result in pseudotumour formation. The innate response involves phagocytosis of implant-derived wear particles by macrophages; this is determined by pattern recognition receptors and results in expression of cytokines, chemokines and growth factors promoting inflammation and osteoclastogenesis; phagocytosed particles can also be cytotoxic and cause cell and tissue necrosis. The adaptive immune response to wear debris is characterised by the presence of lymphoid cells and most likely occurs as a result of a cell-mediated hypersensitivity reaction to cell and tissue components altered by interaction with the material components of particulate wear, particularly metal ions released from cobalt-chrome wear particles.

    Aseptic technique includes the use of sterile surgical gloves for survival surgeries in rodents to minimize the incidence of infections. Exam gloves are much less expensive than are surgical gloves and may represent a cost-effective, readily available option for use in rodent surgery. This study examined the effectiveness of surface disinfection of exam gloves with 70% isopropyl alcohol or a solution of hydrogen peroxide and peracetic acid (HP-PA) in reducing bacterial contamination. Performance levels for asepsis were met when gloves were negative for bacterial contamination after surface disinfection and sham 'exertion' activity. According to these criteria, 94% of HP-PA-disinfected gloves passed, compared with 47% of alcohol-disinfected gloves. In addition, the effect of autoclaving on the integrity of exam gloves was examined, given that autoclaving is another readily available option for aseptic preparation. Performance criteria for glove integrity after autoclaving consisted of: the ability to don the gloves followed by successful simulation of wound closure and completion of stretch tests without tearing or observable defects. Using this criteria, 98% of autoclaved nitrile exam gloves and 76% of autoclaved latex exam gloves met performance expectations compared with the performance of standard surgical gloves (88% nitrile, 100% latex). The results of this study support the use of HP-PA-disinfected latex and nitrile exam gloves or autoclaved nitrile exam gloves as viable cost-effective alternatives to sterile surgical gloves for rodent surgeries.

    2015-05-01

    Complete thoracic ectopia cordis is associated with a uniformly dismal prognosis. The primary challenges of this disorder are (1) returning the heart to the thoracic cavity, (2) stabilizing the chest wall, and (3) repairing the sternal defect. Previously published techniques for achieving these goals have demonstrated very limited success and/or significant morbidity.We present a novel application of a mandibular distraction device as part of staged repair of this historically challenging problem. This method uses immediate stabilization and gradual "retraction" of the sternal remnants, thereby allowing physiologic compensation and avoiding the cardiorespiratory embarrassment associated with returning the heart to the thoracic cavity. Moreover, this technique allows stabilization of the associated sternal cleft and chest wall without the commonly associated morbidity of the currently available techniques.

  7. Biosurfactant production using mixed cultures under non-aseptic conditions

    International Nuclear Information System (INIS)

    The use of surfactants is of increasing interest for remediation of petroleum hydrocarbons in groundwater and soil. Surfactants increase the accessibility of adsorbed hydrocarbons and mobilize immiscible petroleum hydrocarbons for treatment. Biosurfactants have the advantage of biodegradability and non-toxicity over their synthetic counterparts, and can be produced from renewable sources. In this study the production of biosurfactant from molasses was investigated in continuously stirred batch reactors. The effects of substrate concentration, yeast extract and peptone on biomass accumulation and biosurfactant production were investigated. Biosurfactant production was quantified by surface tension reduction and critical micelle dilution (CMD). Biosurfactant production was directly correlated with biomass production, and was improved with the addition of yeast extract. Centrifugation of the whole broth reduced surface tension. The performance of the biosurfactant produced from molasses under non-aseptic condition is comparable to other published results

    Hand hygiene and simple aseptic measures before invasive procedures are effective in reducing rates of healthcare-associated infection. The perceived urgency of a clinical situation in the emergency department, however, may influence medical staff's compliance with good practice in infection control. The aims of this prospective, single-blinded, observational study were twofold. First, to assess doctors' compliance with good practice in hand hygiene between patient episodes and asepsis during invasive procedures in the emergency department. Second, to assess the effect of clinical urgency on compliance with good practice in hand hygiene and asepsis during invasive procedures. Good practice standards for asepsis in invasive procedures and hand hygiene between patient episodes were compiled from a literature search. Doctors' compliance with these standards was observed in two emergency departments (UK and New Zealand). Observed clinical cases were classified as immediate, urgent and non-urgent based on the triage system. There was poor compliance with good practice guidelines for asepsis in invasive procedures in both centres. Staff achieved high compliance with the guidelines in only 27% of cases in the UK and 58% of cases in New Zealand. Clinical urgency did not appear to adversely affect compliance with aseptic good practice. Hand hygiene between patient consultations was very low at 14% in the UK and 12% in New Zealand. Asepsis and hand hygiene was poor in both the UK and New Zealand emergency departments. There may be a need for some compromise in standards of asepsis in very sick patients due to the urgency of the clinical situation. Compliance in all situations especially non-urgent procedures needs to be improved.

Conclusion A number of studies have demonstrated the efficacy of surgical interventions for secondary sternal stabilization, but individual patients may reject this option or may be, for other reasons, no longer operable. The task of primary care physicians and other health care providers is to offer this group of patients an alternative option for pragmatic, inexpensive and effective supportive therapy, of which compression garments are an example.

    Conclusions: In endemic regions, scrub typhus should be considered in the differential diagnosis of aseptic meningitis. Modest elevation of cells in the CSF with lymphocytic pleocytosis and multi-organ involvement may indicate scrub typhus meningitis/meningo-encephalitis.

    Full Text Available OBJECTIVE: To describe the role of magnetic resonance imaging (MRI in the evaluation of patients with chronic and recurrent aseptic meningitis.METHOD: A retrospective study of five patients with aseptic meningoencefalitis diagnosed by clinical and CSF findings. CT scans showed without no relevant findings. RESULTS: MRI showed small multifocal lesions hyperintense on T2 weighted images and FLAIR, with mild or no gadolinium enhancement, mainly in periventricular and subcortical regions. Meningoencephalitis preceded the diagnosis of the underlying disease in four patients (Behçet´s disease or systemic lupus erythematosus. After the introduction of adequate treatment for the rheumatic disease, they did not present further symptoms of aseptic meningoencephalitis. CONCLUSION: Aseptic meningoencephalitis can be an early presentation of an autoimmune disease. It is important to emphasize the role of MRI in the diagnosis and follow-up of these patients.

    Full Text Available Splenic abscesses are most often secondary to aerobic bacterial infections due to Streptococcus, Staphylococcus, and Enterococcus species of organisms. Sterile splenic abscesses rarely occur and diagnosis and treatment of those are challenging. We report a case of a previously healthy young female presenting with aseptic splenic abscesses as the initial manifestation of Crohn’s disease along with a review of the literature on aseptic splenic abscess as an extraintestinal manifestation of Crohn’s disease.

    Full Text Available Abstract Background Aseptic meningitis is a relatively frequent childhood disease and virologic data suggest that enteroviruses are the commonest etiologic agents. We evaluated the epidemiologic characteristics of aseptic meningitis in Daejeon, South Korea from 1987 to 2003. Methods 2201 medical records of children with aseptic meningitis admitted to The Catholic University of Korea, Daejeon St Mary's Hospital were retrospectively analyzed. Results Outbreaks of aseptic meningitis were observed in 1990, 1993, 1996, 1997, 2001 and 2002. The age distribution of cases was relatively uniform, with a higher incidence in those aged P = 0.001. Neurologic sequelae were observed in 0.7% of the patients. Conclusion Aseptic meningitis, rare before the 1980s in Korea, has since become a common clinical entity. Since 1990, outbreaks of aseptic meningitis have occurred every 1 to 3 years in Daejeon in keeping with Korea-wide epidemics. The frequency of disease affecting children less than one year of age may reflect herd immunity to the epidemic strain.

  15. The history of the management of sternal osteomyelitis and mediastinitis – from Hippocrates until today

    Full Text Available Even during the time of Hippocrates, Galen and their colleagues recognized mediastinal affections. However, they were not considered with the surgical treatment. First progress in the treatment options of this severe disease, still denoted as ‘terra incognita’, over to today’s gold standard are pictured.The mediastinitis-registry which was founded by the German Society for Thoracic and Cardiovascular Surgery (DGTHG in 2011 and the recent establishment of the study group to adopt a guideline ‘diagnosis and therapy of postoperative mediastinitis/sternal osteomyelitis following cardiac surgery’ are attempts to a standardization of the treatment. Substantial advancement in the treatment of postoperative mediastinitis could be achieved in the past. The mortality dropped as low as less than 10%. With these implementations more benefit for the patients’ outcome can be expected.

    2002-06-01

    The number of redo cardiac operations, especially coronary artery bypass grafting (CABG), has recently been increasing mainly due to the failure of saphenous vein grafts. Re-opening a median sternotomy is troublesome, because of possible adhesion of the heart to the sternum. Preoperative computed tomography is quite useful and helpful in determining the degree of the adhesion of the heart and ascending aorta to the back of the sternum. We report here a safe and useful technique for sternal re-entry using a retractor for harvesting the internal thoracic artery (ITA). When re-opening a median sternotomy the incision is made to the sternal wires; the wires are then cut and removed. Small rake retractors, which are connected to the ITA retractor, are hooked to both ends of the left side of the sternum. The ITA retractor is gently wound up to lift up the sternum. An oscillating saw is then applied to divide the anterior table of the sternum. When the posterior table of the sternum is carefully divided, the left side of the sternum is automatically elevated slightly. Complete division of the sternum can be confirmed by this slight elevation. If the left side of the sternum is elevated a little bit more by the ITA retractor, the dissection of the adhesion between the sternum and the heart can be performed without assistance. This technique is most beneficial for a case of redo CABG with the use of the left ITA, but it can be applied in any patients who previously underwent median sternotomy.

    2016-06-01

    Flail chest is a life-threatening situation that paradoxical movement of the thoracic cage was caused by multiply fractured ribs in two different planes, or a sternal fracture, or a combination of the two. The methods to achieve stability of the chest wall are controversy between surgical fixation and mechanical ventilation. We report a case of a 33-year-old man who fell from a high place with fail chest due to multiple rib fractures bilaterally and horizontal sternal fracture. The conventional surgical stabilization using metal plates by access to the front of the sternum could not provide stability of the flail segment because the fracture surface was obliquely upward and there were multiple bilateral rib fractures adjacent the sternum. The Nuss procedure was performed for supporting the flail segment from the back. Flail chest was resolved immediately after the surgery. The patient was weaned from the mechanical ventilation on third postoperative day successfully and was ultimately discharged without any complications.

    Chickenpox is caused by the varicella zoster virus (VZV) and may be more severe in adults than in children. Central nervous system (CNS) manifestations of chickenpox and VZV are uncommon, for example, encephalitis and cerebellar ataxis. Viral (aseptic) meningitis is a rare CNS complication of VZV. The cerebrospinal fluid (CSF) profile in VZV viral (aseptic) meningitis is indistinguishable from other causes of viral meningitis. The clue to most of the diagnoses of VZV aseptic meningitis is based on the temporal relationship between antecedent or concomitant chickenpox. Chickenpox is a clinical diagnosis based on the appearance and distribution of the rash. The rash of chickenpox is vesicular/pruritic and typically appears in crops over 3 successive days. VZV vesicles are fragile, superficial, and surrounded by a erythematous halo. Common nonspecific laboratory findings in chickenpox include leukopenia, thrombocytopenia, and elevated serum transaminases (serum glutamate-oxaloacetate transaminase/serum glutamate-pyruvate transaminase). The erythrocyte sedimentation rate (ESR) is not highly elevated in chickenpox. In VZV aseptic meningitis, the CSF shows a lymphocytic pleocytosis with normal protein, glucose, and lactic acid levels. CSF red blood cells are not a feature of VZV meningitis. We present the case of a healthy unimmunized adult who was hospitalized with chickenpox complicated by VZV aseptic meningitis with an unusually severe headache and nuchal rigidity that occurred during hospitalization.

  19. Results of Three-Dimensional Conformal Radiation Therapy for the Treatment of a Solitary Sternal Relapse of Breast Cancer

    International Nuclear Information System (INIS)

    To evaluate the response and survival rate after three-dimensional conformal radiation therapy (3D-CRT) of patients with a solitary sternal relapse of breast cancer. Seventeen patients between May 1996 and June 2005 were evaluated with the salvage 3D-CRT treatment of a solitary sternal relapse of breast cancer. The treatment fields included the gross tumor volume with 2 cm margins. The total radiation dose was 35.0 ∼61.5 Gy (biologic effective dose of 43.7 ∼76.9 Gy10 using an α/β ratio of 10 Gy), with a daily dose of 1.8∼3.0 Gy. The tumor response was evaluated by the change in maximum tumor size via follow up CT scans 1∼3 months after the completion of treatment. An objective tumor response was achieved in all patients, with a complete response in 5 patients and a partial response in 12 patients. The 5-year overall survival rate was 51.9% (median survival time: 27 months), and the most important factor affecting overall survival was the disease-free interval (interval from primary surgery of breast cancer to the development of sternal metastasis): The 5-year overall survival rate was 61.8% for patients with a disease-free interval ≥12 months and 0.0% for patients < with disease-free interval <12 months (p=0.03). The response to 3D-CRT was good in patients with solitary sternal relapse of breast cancer. Particularly, patients with long disease-free interval from primary surgery survived significantly longer than patients with short disease-free interval from primary surgery

  20. The use of antibiotic-impregnated cement beads in the management of sternal osteomyelitis after treatment for malignant lymphoma

    International Nuclear Information System (INIS)

    Currently, the majority of patients who develop Hodgkin's disease can be cured with radiotherapy and/or chemotherapy. A long follow up of cured patients has shown that the cumulative toxicity from treatment related complication rivals the mortality from Hodgkin's disease. We present a 38-year old male with Hodgkin's disease, treated with radiation and chemotherapy, who developed cardiac infarction and severe mediastinal fibrosis. After median sternotomy for cardiac bypass operation, he suffered from sternal osteitis and superior mediastinitis. A radical debridement must be avoided to protect the bypassed conduit embedded in the extended severe mediastinal fibrosis. Then after appropriate debridement and management of methicillin-resistant Staphylococcus aureus (MRSA) infection, latissimus dorsi myocutaneous flap transfer and use of vancomycin-impregnated cement beads achieved infection control. In this study we present our experience with bibliographical discussion. With the concept presented in this study, however, a consistent cure and prevention from subsequent infection-related morbidity and mortality were achieved even in the subset of the most severe, recalcitrant cases of sternal osteitis, and with an unacceptable rate of complications. This justifies the invasive nature of the procedure and suggests its application not only as a salvage operation for failures after previous interventions, but also as a primary approach for severe sternal osteomyelitis.

    Viral meningitis is the most common cause of aseptic meningitis. Use of the polymerase chain reaction (PCR) has increased the ability to determine the etiology of viral meningitis. This study used PCR analysis to evaluate the etiology of aseptic meningitis in 177 previously healthy adults over a 5-year period, as well as analyzing the clinical characteristics, cerebrospinal fluid (CSF) findings, and prognosis according to each etiology. The most frequent cause of aseptic meningitis was enterovirus (EV), followed by varicella zoster virus (VZV). Patients with EV meningitis were significantly younger than those with VZV meningitis. The percentage of lymphocytes in white blood cell counts and protein concentrations in the CSF differed significantly among patients with EV, VZV and meningitis of undetermined etiology. Younger age and lower percentage of lymphocyte and protein level in CSF analysis may be suggestive of EV meningitis. Further prospective studies are warranted to identify the correlations between the clinical characteristics and the etiologies of meningitis.

    Concerns have been raised about whether it is possible to perform aseptic procedures within a community setting. Hallett (2000) has described how community nurses often have a fatalistic view about whether such procedures can really be performed at home. At the same time there has been an increase in the number of patients being cared for at home who need interventions which must adhere to the principles of asepsis. While it has been acknowledged for some time that community nurses must be resourceful and adapt the procedure, the view that community nurses cannot really perform aseptic procedures is a fairly new phenomenon. This article explores the reasons why concerns about the performance of aseptic procedures in the community may have arisen and what steps can be taken to address these concerns to ensure that care at home is both safe and effective.

  3. An investigation of the aseptic loosening of an AISI 316L stainless steel hip prosthesis

    International Nuclear Information System (INIS)

    The total replacement of joints by the implantation of permanently indwelling prosthetic components has been one of the major successes of modern surgery in terms of relieving pain and correcting deformity. However, the aseptic loosening of a prosthetic-joint component is the most common reason for joint-revision surgery. Furthermore, it is thought that wear particles are one of the major contributors to the development and perpetuation of aseptic loosening. The aim of the present study was to identify the factors related to the aseptic loosening of an AISI 316L stainless steel total hip prosthesis. The stem was evaluated by x-ray photoelectron spectroscopy, with polished and rough regions being analyzed in order to establish the differences in the chemical compositions of both regions. Specific areas were examined using scanning electron microscopy with energy dispersive x-ray spectroscopy and light microscopy.

    The use of plant oils as feedstock for the biodiesel manufacture has many drawbacks, thus, the interest has turned to single cell oil (SCO) as an alternative. However, the production of SCO is still too expensive, mainly due to the low oil productivity and the high cost of medium sterilization required. In this work raw glycerol was converted into SCO by oleaginous Zygomycetes under non-aseptic conditions on selective (i.e., containing essential oils and/or antibiotics) nitrogen limited media. The obtained data showed that although bacterial populations inhibited the fungal growth, lipid accumulation remained unaffected by the presence of bacteria in the growth medium compared to control experiments (conducted under aseptic conditions). Therefore, a two-stage process was developed in which growth was performed under aseptic conditions (1st stage) followed by lipid accumulation performed under non-aseptic conditions (2nd stage) in the presence of thyme essential oil as an antibacterial agent. Large amounts of lipids were accumulated inside the mycelia, yielding around 13% wt/wt of oil per glycerol consumed. PMID:25335774

    Consumer awareness and demand for nutritious yet inexpensive food products call for innovative processing techniques that have both safety and quality as primary objectives. These challenges appear to have been met by aseptic processing techniques, especially for liquid and high-acid foods. However, the extension of aseptic processing principles to low-acid foods containing discrete particles in viscous sauces has not been approved by regulatory agencies, particularly in North America. This apparent limitation is due primarily to the lack of adequate temperature monitoring devices to keep track of particles in dynamic motion, as well as to the residence time distribution of particles flowing in the continuous heat-hold-cool sections of the aseptic processing system. These problems have prompted active research to describe the phenomenal behavior of particulates through sound mathematical modeling and computer simulators. The accuracy of mathematical models depends heavily on how accurate input parametric values are. These parameters include the thermophysical properties of the carrier fluid and particles, as well as the aseptic processing system characteristics in relation to residence time distribution and the fluid-to-particle interfacial heat transfer coefficient. Apparently, several contradictory findings have been reported in the literature with respect to the effect of various processing parameters on the above-mentioned input parametric values. The need therefore arises for more collaborative studies involving the industry and academia. This review brings to perspective, the current status on the aseptic processing of particulate foods with respect to the critical processing parameters which affect the fluid-to-particle convective heat transfer coefficient associated with particulate laden products.

    Full Text Available Thomas P Vacek, Shahnaz Rehman, Shipeng Yu, Ankush Moza, Ragheb Assaly Department of Internal Medicine, The University of Toledo Medical Center, Toledo OH, USAAbstract: Chest pain requires a detailed differential diagnosis with good history-taking skills to differentiate between cardiogenic and noncardiogenic causes. Moreover, when other symptoms such as fever and elevated white blood cell count are involved, it may be necessary to consider causes that include infectious sources. A 53-year-old female with no significant past medical history returned to the hospital with recurrent complaints of chest pain that was constant, substernal, reproducible, and exacerbated with inspiration and expiration. The chest pain was thought to be noncardiogenic, as electrocardiography did not demonstrate changes, and cardiac enzymes were found to be negative for signs of ischemia. The patient's blood cultures were analyzed from a previous admission and were shown to be positive for Staphylococcus aureus. The patient was started empirically on vancomycin, which was later switched to ceftriaxone as the bacteria were more sensitive to this antibiotic. A transthoracic echocardiogram did not demonstrate any vegetation or signs of endocarditis. There was a small right pleural effusion discovered on X-ray. Therefore, computed tomography as well as magnetic resonance imaging of the chest were performed, and showed osteomyelitis of the chest. The patient was continued on intravenous ceftriaxone for a total of 6 weeks. Tests for HIV, hepatitis A, B, and C were all found to be negative. The patient had no history of childhood illness, recurrent infections, or previous trauma to the chest, and had had no recent respiratory infections, pneumonia, or any underlying lung condition. Hence, her condition was thought to be a case of primary sternal osteomyelitis without known cause.Keywords: substernal, pleuritic, myocardial infarction, differential

    Full Text Available Patients with an anterior mediastinal mass pose significant risk for cardiorespiratory compromise during surgical procedures and general anesthesia. Several techniques have been described to reverse airway obstruction in these patients. In extreme circumstances, patients may require cardiac bypass or extracorporeal membrane oxygenation (ECMO until definitive treatment of the mass and patient stabilization is achieved. We present a case in which the RulTract® system was used for emergency sternal elevation as a bridge to ECMO in acute respiratory collapse in an 11-year-old female with a minimally symptomatic anterior mediastinal mass.

    Congenital sternal cleft is a rare chest wall malformation. Because of the flexibility of the chest in infants, surgical repair should be performed by primary closure in the neonatal period. In adolescents and adults, different techniques have been suggested to overcome the lack of sternal bone tissue. We describe a very rare case of an 18-year-old woman with a complete bifid sternum associated with pectus excavatum for whom a satisfactory cosmetic and functional result was obtained by adequate surgical planning, which entailed a combination of two standardized surgical techniques.

    Several studies have focused on the clinical and biological characteristics of meningitis in order to distinguish between bacterial and viral meningitis in the emergency setting. However, little is known about the etiologies and outcomes of aseptic meningitis in patients admitted to Internal Medicine.The aim of the study is to describe the etiologies, characteristics, and outcomes of aseptic meningitis with or without encephalitis in adults admitted to an Internal Medicine Department.A retrospective cohort study was conducted in the Internal Medicine Department of the Lariboisière Hospital in Paris, France, from January 2009 to December 2011. Clinical and biological characteristics of aseptic meningitis were recorded. These included cerebrospinal fluid analysis, results of polymerase chain reaction testing, final diagnoses, and therapeutic management.The cohort included 180 patients fulfilling the criteria for aseptic meningitis with (n = 56) or without (n = 124) encephalitis. A definitive etiological diagnosis was established in 83 of the 180 cases. Of the cases with a definitive diagnosis, 73 were due to infectious agents, mainly enteroviruses, Herpes Simplex Virus 2, and Varicella Zoster Virus (43.4%, 16.8%, and 14.5% respectively). Inflammatory diseases were diagnosed in 7 cases. Among the 97 cases without definitive diagnoses, 26 (26.8%) remained free of treatment throughout their management whereas antiviral or antibiotic therapy was initiated in the emergency department for the remaining 71 patients. The treatment was discontinued in only 10 patients deemed to have viral meningitis upon admission to Internal Medicine.The prevalence of inflammatory diseases among patients admitted to internal medicine for aseptic meningitis is not rare (4% of overall aseptic meningitis). The PCR upon admission to the emergency department is obviously of major importance for the prompt optimization of therapy and management. However, meningitis due to viral agents or

    Increased bone formation resulting from mechanical loading is well documented; however, the interactions of the mechanotransduction pathways are less well understood. Endothelin-1, a ubiquitous autocrine/paracrine signaling molecule promotes osteogenesis in metastatic disease. In the present study, it was hypothesized that exposure to big endothelin-1 (big ET1) and/or mechanical loading would promote osteogenesis in ex vivo trabecular bone cores. In a 2×2 factorial trial of daily mechanical loading (-2000με, 120cycles daily, "jump" waveform) and big ET1 (25ng/mL), 48 bovine sternal trabecular bone cores were maintained in bioreactor chambers for 23days. The bone cores' response to the treatment stimuli was assessed with percent change in core apparent elastic modulus (ΔEapp), static and dynamic histomorphometry, and prostaglandin E2 (PGE2) secretion. Two-way ANOVA with a post hoc Fisher's LSD test found no significant treatment effects on ΔEapp (p=0.25 and 0.51 for load and big ET1, respectively). The ΔEapp in the "no load + big ET1" (CE, 13±12.2%, p=0.56), "load + no big ET1" (LC, 17±3.9%, p=0.14) and "load + big ET1" (LE, 19±4.2%, p=0.13) treatment groups were not statistically different than the control group (CC, 3.3%±8.6%). Mineralizing surface (MS/BS), mineral apposition (MAR) and bone formation rates (BFR/BS) were significantly greater in LE than CC (p=0.037, 0.0040 and 0.019, respectively). While the histological bone formation markers in LC trended to be greater than CC (p=0.055, 0.11 and 0.074, respectively) there was no difference between CE and CC (p=0.61, 0.50 and 0.72, respectively). Cores in LE and LC had more than 50% greater MS/BS (p=0.037, p=0.055 respectively) and MAR (p=0.0040, p=0.11 respectively) than CC. The BFR/BS was more than two times greater in LE (p=0.019) and LC (p=0.074) than CC. The PGE2 levels were elevated at 8days post-osteotomy in all groups and the treatment groups remained elevated compared to the CC group on days 15

    Aseptic cavernous sinus thrombosis (CST) is rare and may clinically masquerade as a carotid cavernous fistula. Conventional management includes oral anticoagulation, but cases of ocular hypertension affecting vision may require more aggressive intervention. We report a case of a woman with spontaneous bilaterally occluded cavernous sinuses with elevated intraocular pressure (IOP), which resolved immediately following unilateral superior ophthalmic vein (SOV) sacrifice. She was subsequently placed on oral anticoagulants. By 4 months postoperatively her IOP was normalized and her vision had improved. Repeat angiography demonstrated stable venous filling, with some mild improvement of flow through the cavernous sinus. Coil-mediated sacrifice of the SOV might be an effective means to relieve ocular hypertension and preserve vision in the setting of aseptic CST.

    Full Text Available BACKGROUND: Human enteroviruses (HEVs are common causes of acute meningitis. However, there is limited information about HEV associated with aseptic meningitis in mainland China because it has not been classified as a notifiable disease. OBJECTIVES: To characterize the HEVs associated with sporadic aseptic meningitis in China and to analyze their genetic features. STUDY DESIGN: Cerebrospinal fluid, throat swab and feces specimens were collected from patients with aseptic meningitis in 5 sentinel hospitals in Shandong Province, China between 2006 and 2012. Virological investigation (viral isolation and molecular identification and phylogenetic analysis were performed. RESULTS: A total of 437 hospitalized patients were reported, and enteroviruses were detected in the specimens from 84 patients (19.2% and were identified into 17 serotypes. The nine main serotypes were echovirus (E 30 (27.4%, EV71 (13.1%, coxsackievirus (CV B1 (9.5%, CVB3 (7.1%, CVB5 (7.1%, E6 (7.1%, E9 (7.1%, CVA9 (6.0%, and CVA10 (3.6%. Monthly distribution of isolated enteroviruses revealed a major peak in summer-fall season and a small second peak in winter constituted totally by EV71. Sequence analysis on VP1 coding region suggested Shandong strains had great genetic divergence with isolates from other countries. CONCLUSIONS: Multiple serotypes were responsible for enterovirus meningitis in mainland China. Aseptic meningitis caused by EV71 and coxsackie A viruses-the predominant pathogens for the hand, foot, and mouth disease-is currently an important concern in mainland China.

    Drug induced aseptic meningitis is a rare but challenging diagnosis, most commonly reported with nonsteroidal anti-inflammatory drugs and antibiotics. Trimethoprim/sulfamethoxazole is a sulfonamide that is widely used in clinical practice for the treatment and prophylaxis of various infections. Drug induced aseptic meningitis, when seen with trimethoprim/sulfamethoxazole, occurs predominantly in patients with some degree of immune compromise and is less commonly seen in immune competent individuals. The patient often exhibits the classic symptoms of meningitis. Early diagnosis is important, since the cessation of the antibiotic leads to rapid clinical improvement. Trimethoprim/sulfamethoxazole induced aseptic meningitis has been underreported to FDA/MED-WATCH program. Here we report two cases of trimethoprim/sulfamethoxazole: an immune competent individual and immune compromised individual, both of which presented with signs of meningitis and a negative infectious workup. Trimethoprim/sulfamethoxazole is an uncommon and mysterious adverse reaction to a commonly used antibiotic. It should be considered in the differential diagnosis of patients presenting with acute signs and symptoms of meningitis especially after infectious causes have been ruled out. PMID:27579194

    To evaluate the sonographic features of mesenteric lymphadenopathy in childhood epidemic aseptic meningitis and to assess their clinical significance. Thirty-three patients (25 male, 8 female: mean age, 8.6 years) with a diagnosis of aseptic meningitis were prospectively evaluated with abdominal ultrasonography for the presence of enlarged mesenteric nodes. The size and number of enlarged mesenteric lymph nodes were analyzed in relationship with the patient's age, between the patients with abdominal pain or diarrhea (16 cases, 48%) and asymptomatic patients (17 cases, 52%). Mesenteric lymphadenopathy was seen in 31 patients (94%), all 16 symptomatic and 15 of the 17 asymptomatic patients. The number of enlarged nodes was most prevalent between 6-10, seen in 16 patients (52%) and the largest node ranged in size from 4 to 8 mm. Among the 31 patients with mesenteric lymphadenopathy, the mean size of the largest node was statistically different between the symptomatic (6.0 mm) and asymptomatic (5.0 mm) groups (p = 0.021). The number of enlarged nodes and the patient's age were not statistically different between the two groups. Mesenteric lymphadenopathy was seen in almost all cases of childhood epidemic aseptic meningitis, and may be related to the mesenteric lymphadenitis caused by enterovirus

    Aseptic loosening is a major cause of revision surgery of total hip arthroplasty (THA). Only few host factors affecting aseptic loosening have been identified until now, although they are urgently needed to identify and possibly treat those patients at higher risk for aseptic loosening. To determine whether the functional single nucleotide polymorphism (SNP) c.-938C>A (rs2279115), located in the promoter region of the BCL2 gene has an impact on aseptic loosening of THA we genotyped and analyzed 234 patients suffering from aseptic loosening and 231 patients after primary THA. The polymorphism is associated with risk for aseptic loosening with the CC genotype at highest risk for aseptic loosening, Odds Ratio CC vs. AA 1.93, 95%CI 1.15-3.25, p = 0.013. In contrast, low risk AA genotype carriers that still developed aseptic loosening showed a significantly shorter time to aseptic loosening than patients carrying the C allele (p = 0.004). These results indicate that the BCL2 -938C>A polymorphism influences the occurrence and course of aseptic loosening and suggests this polymorphism as an interesting candidate for prospective studies and analyses in THA registers.

  8. Clavicles, interclavicles, gastralia, and sternal ribs in sauropod dinosaurs: new reports from diplodocidae and their morphological, functional and evolutionary implications.

    Ossified gastralia, clavicles and sternal ribs are known in a variety of reptilians, including dinosaurs. In sauropods, however, the identity of these bones is controversial. The peculiar shapes of these bones complicate their identification, which led to various differing interpretations in the past. Here we describe different elements from the chest region of diplodocids, found near Shell, Wyoming, USA. Five morphotypes are easily distinguishable: (A) elongated, relatively stout, curved elements with a spatulate and a bifurcate end resemble much the previously reported sauropod clavicles, but might actually represent interclavicles; (B) short, L-shaped elements, mostly preserved as a symmetrical pair, probably are the real clavicles, as indicated by new findings in diplodocids; (C) slender, rod-like bones with rugose ends are highly similar to elements identified as sauropod sternal ribs; (D) curved bones with wide, probably medial ends constitute the fourth morphotype, herein interpreted as gastralia; and (E) irregularly shaped elements, often with extended rugosities, are included into the fifth morphotype, tentatively identified as sternal ribs and/or intercostal elements. To our knowledge, the bones previously interpreted as sauropod clavicles were always found as single bones, which sheds doubt on the validity of their identification. Various lines of evidence presented herein suggest they might actually be interclavicles - which are single elements. This would be the first definitive evidence of interclavicles in dinosauromorphs. Previously supposed interclavicles in the early sauropodomorph Massospondylus or the theropods Oviraptor and Velociraptor were later reinterpreted as clavicles or furculae. Independent from their identification, the existence of the reported bones has both phylogenetic and functional significance. Their presence in non-neosauropod Eusauropoda and Flagellicaudata and probable absence in rebbachisaurs and Titanosauriformes shows a

    Postoperative radiotherapy is widely performed in the treatment of patients with lymph node metastases from carcinoma of the breast, however, depending on the dose, cases are seen in which radiation ulcers develop and require surgical management. In the present paper we report a patient in whom postoperative radiotherapy was performed because parasternal lymph node metastasis was discovered at the time of surgery and who 15 months later experienced thoracic wall recurrence. Since metastasis to the contralateral lung was observed at that time, reoperation was not attempted, and when radiotherapy was again administered, an extensive radiation ulcer developed in association with sternal and costal necrosis. The skin and subcutaneous tissue together with the sternum and ribs were widely resected followed by the thoracoplasty using a latissimus dorsi musculocutaneous flap. Since there was no postoperative infection, the skin flap was accepted well, and the outcome was satisfactory from the standpoint of quality of life, we have reported the case. (author).

  10. Legal, ethical, and procedural bases for the use of aseptic techniques to implant electronic devices

    animals often mask the signs of infection to avoid attracting predators (Wobeser 2006). Guidance specific to sterilization of electronic devices for implantation is limited in the wildlife record (Burger et al. 1994; Mulcahy 2003). Few biologists have been formally trained in aseptic technique, but most biologists know that electronic devices should be treated in some way to reduce the chance for infection of the host animal by bacteria, viruses, parasites, and fungi. Most biologists (73%) who implant devices into fishes believe aseptic techniques are important (Wagner and Cooke 2005). However, I maintain that many biologists find it difficult to place the concept of asepsis into practice in their work because of confusion about what constitutes aseptic technique, a lack of surgical knowledge and training, the perception of increased costs, or the belief that aseptic surgeries are impractical or unnecessary for their application. Some have even argued that, while compromising surgical techniques in the field might result in complications or mortalities, the money saved would allow for a compensatory increase in sample size (Anderson and Talcott 2006). In this paper I define aseptic surgical techniques, document the legal and professional guidance for performing aseptic surgeries on wild animals, and present options for sterilizing electronic devices and surgical instruments for field use.

Aseptic loosening and periprosthetic osteolysis are believed to be caused, at least in part, by increased polyethylene (PE) wear rate via particle disease. Based on it, increased PE wear rate should be associated with aseptic loosening regardless of the type of implant. Methods We analyzed data from 155 revisions of ABG I hip prostheses to examine the influence of p...

    In 2006, an outbreak of aseptic meningitis was noted in Taiwan. From January to October 2006, a total of 3283 specimens collected from patients with viral infection, including 173 cerebrospinal fluid (CSF) samples, were examined for virus isolation and identification. Overall, 339 enterovirus (EV)-positive cases were identified by virus culture: echovirus 18 (E18) formed the majority (27.4 %, 93 cases), followed by coxsackievirus B2 (13.8 %, 47 cases) and coxsackievirus A2 (10.8 %, 37 cases). The manifestations of the 93 E18 cases were aseptic meningitis (44.1 %), viral exanthema (23.6 %), acute tonsillitis (15.1 %), acute pharyngitis (14.0 %), acute gastritis (11.8 %), herpangina (7.5 %) and bronchopneumonia (5.3 %). Of 107 E18 isolates identified, 100, 62.5 and 19 % were obtained following culture in RD, MRC-5 and A549 cells, respectively. E18 was identified most frequently from throat swabs (67.2 %) and less frequently from stool samples (15.9 %) and CSF (16.8 %). The detection rate of E18 was 78.2 % from CSF, 50 % from stool samples and 22.9 % from throat swabs. Phylogenetic relationships among the E18 strains were examined. Analysis of the partial VP1 gene showed 3.7-23.8 % variation in sequence compared with sequences from GenBank and, notably, the amino acid change V152S was detected in a protruding loop within the VP1 protein. These results indicate that a genetic variant of E18 was circulating and caused an outbreak of aseptic meningitis in Taiwan in 2006.

    Full Text Available We report a case of a 19-year-old woman who developed intracranial hypertension as an unusual clinical complication of severe aseptic meningoencephalitis probably due to a diminished cerebrospinal fluid reabsorption capacity or leptomeningeal transudation as a consequence of blood-brain barrier dysfunction. These severe inflammatory changes were accompanied by prominent leptomeningeal contrast enhancement best visualized on fluid-attenuated inversion recovery magnetic resonance imaging. In such a prolonged course, a continuous lumbar drainage might be a temporary option to provide rapid symptom relief to the patient.

    Aseptic bone necrosis has many well recognized etiologies: caisson disease, corticosteroids, alcohol, Gaucher's disease and sickle cell anemia being a few of a long list. Little attention has been paid to metastatic disease as a possible cause and we were unable to find reference in the literature to this association. We present imaging features of metastatic Ewing's sarcoma involving the vertebral spine, which, in certain aspects, mimics other well-known entities of this region, such as Kuemmell's and Scheuermann's diseases.

    Sepsis is a major cause for death worldwide. Numerous interventional trials with agents neutralizing single proinflammatory mediators have failed to improve survival in sepsis and aseptic systemic inflammatory response syndromes. This failure could be explained by the widespread gene expression dysregulation known as “genomic storm” in these patients. A multifunctional polyspecific therapeutic agent might be needed to thwart the effects of this storm. Licensed pooled intravenous immunoglobulin preparations seemed to be a promising candidate, but they have also failed in their present form to prevent sepsis-related death. We report here the protective effect of a single dose of intravenous immunoglobulin preparations with additionally enhanced polyspecificity in three models of sepsis and aseptic systemic inflammation. The modification of the pooled immunoglobulin G molecules by exposure to ferrous ions resulted in their newly acquired ability to bind some proinflammatory molecules, complement components and endogenous “danger” signals. The improved survival in endotoxemia was associated with serum levels of proinflammatory cytokines, diminished complement consumption and normalization of the coagulation time. We suggest that intravenous immunoglobulin preparations with additionally enhanced polyspecificity have a clinical potential in sepsis and related systemic inflammatory syndromes. PMID:26701312

    Full Text Available Introduction Bacterial meningitis is a known infectious disease which occurs at early ages and should be promptly diagnosed and treated. Bacterial and aseptic meningitis are hard to be distinguished. Therefore, physicians should be highly informed and experienced in this area. The main aim of this study was to suggest a system for distinguishing between bacterial and aseptic meningitis, using fuzzy logic.    Materials and Methods In the first step, proper attributes were selected using Weka 3.6.7 software. Six attributes were selected using Attribute Evaluator, InfoGainAttributeEval, and Ranker search method items. Then, a fuzzy inference engine was designed using MATLAB software, based on Mamdani’s fuzzy logic method with max-min composition, prod-probor, and centroid defuzzification. The rule base consisted of eight rules, based on the experience of three specialists and information extracted from textbooks. Results Data were extracted from 106 records of patients with meningitis (42 cases with bacterial meningitis in order to evaluate the proposed system. The system accuracy, specificity, and sensitivity were 89%, 92 %, and 97%, respectively. The area under the ROC curve was 0.93, and Kappa test revealed a good level of agreement (k=0.84, P

    The study evaluates the clinical significance of CXCL13 (leukocyte chemoattractant synthesized in CSF ) in Lyme neuroborreliosis (LNB) and other aseptic CNS infections. 244 patients with symptoms of neuroinfection and/or LNB were divided into groups: A - patients with LNB-positive antibodies in serum and CSF (96) or CSF only (14); B - patients with aseptic non-borrelial neuroinfections (82); C - negative controls (52). Group A was divided into A1-A4 according to pleocytosis in CSF and AIIgG positivity. The highest CSF CXCL13 concentrations (max. 81,287.60pg/ml; median 1766.90pg/ml) were in A1 (positive AI, pleocytosis) and A3 (negative AIIgG, pleocytosis; max. 7201,60pg/ml, median 56.22pg/ml). A2 (positive AI without pleocytosis) and A4 (negative AI without pleocytosis) had low CXCL13 levels - A2 max. 650.50pg/ml (medianAI positivity. PMID:27538636

  20. Irradiation as a means of sterilizing packaging materials for aseptic systems

    International Nuclear Information System (INIS)

    Long shelf life of foodstuffs is essential in order to feed the nations of the world. For 'wet' products which quickly deteriorate in air, the use of refrigeration, retort processing and preservatives can be considered. For example, the metal can will continue to be a reliable means of keeping meat and vegetable products in good condition for long periods at ambient conditons. Today, people require food items to be free of preservatives and with a flavour and texture very close to the original, at all times of the year, at lowest cost. Minimal heat processing and immediate filling into a pre-sterilised container without any possibility of contact with the atmosphere, is the logical route to take to meet these requirements and constitutes an aseptic system. The filled product remains in prime condition for many months without the need for refrigeration and preservatives. Irradiation is a convenient and cheap means of pre-sterilising plastic bags for Bag-in-Box systems and the writer will describe how fruit juices and fruit purees are now being packaged aseptically in South Africa and overseas

    Human parechoviruses (HPeV) are classified into 14 genotypes. HPeV1 and HPeV2 are the most prevalent genotypes in young children, which have been associated with mild to severe diseases. This study was conducted to investigate the involvement of HPeVs in aseptic meningitis and sepsis-like illness in Iran. Viral RNA was extracted from 148 cerebrospinal fluid samples from children meningitis and/or sepsis-like illness. Specific HPeV, HEV real-time PCR and HPeV typing were done to identify the infection rate of these viruses. HPeV and HEV were detected in 64 (43.24 %), 31 (20.94 %) of 148 patients with 10 (6.75 %) coinfection. VP1/VP3 junction region was successfully sequenced from 12 of the HPeV-positive specimens, and all of them were identified as HPeV1. HPeV was more prevalent than HEV in both aseptic meningitis and sepsis-like illness, so further studies are needed to understand the disease burden of HPeV infections, and clinical manifestations especially in specific illnesses of possible viral etiology. Direct detection of these viruses leads to reduce hospitalization and use of antibiotic, which are often followed by other complications in neonates and young children.

    Background: Heart rupture resulting in lethal bleeding is a devastating complication associated with negative pressure wound therapy (NPWT) in patients with deep sternal wound infection (DSWI). We have previously reported that the use of a protective HeartShield device in combination with NPWT decreases the risk of damage to the heart. This article presents a retrospective analysis of NPWT duration with and without the HeartShield device. Subjects and patients: The study included 6 patients t...

    We describe a case of aseptic meningitis following the administration of moxifloxacin in a 45-year-old man with human immunodeficiency virus (HIV). At presentation he was receiving tuberculosis treatment on a modified regimen following severe hepatotoxicity; this included moxifloxacin, started 8 days previously. Initial cerebrospinal fluid (CSF) analysis was grossly abnormal. Anti-viral and -bacterial treatments were started. All microbiological tests proved negative and his moxifloxacin was withheld resulting in a complete normalisation of CSF. Drug-induced aseptic meningitis is a diagnosis of exclusion and presents a serious diagnostic dilemma. The decision to withhold medication cannot be taken lightly.

    Full Text Available Abstract Negative-pressure wound therapy, commercially known as vacuum-assisted closure (V.A.C.® therapy, has become one of the most popular (and efficacious interim (prior to flap reconstruction or definite methods of managing deep sternal wound infection. Complications such as profuse bleeding, which may occur during negative-pressure therapy but not necessarily due to it, are often attributed to a single factor and reported as such. However, despite the wealth of clinical experience internationally available, information regarding certain simple considerations is still lacking. Garnering information on all the factors that could possibly influence the outcome has become more difficult due to a (fortunate decrease in the incidence of deep sternal wound infection. If more insight is to be gained from fewer clinical cases, then various potentially confounding factors should be fully disclosed before complications can be attributed to the technique itself or improvements to negative-pressure wound therapy for deep sternal wound infection can be accepted as evidence-based and the guidelines for its use adapted. The authors propose the adoption of a simple checklist in such cases.

    Full Text Available Abstract Background We studied which factor could predict aseptic loosening in ABG I hip prosthesis with hydroxyapatite coating. Aseptic loosening and periprosthetic osteolysis are believed to be caused, at least in part, by increased polyethylene (PE wear rate via particle disease. Based on it, increased PE wear rate should be associated with aseptic loosening regardless of the type of implant. Methods We analyzed data from 155 revisions of ABG I hip prostheses to examine the influence of patient, implant, surgery, and wear related factors on the rate of aseptic loosening at the site of the cup. This was calculated by stepwise logistic regression analysis. The stability of the implant and severity of bone defects were evaluated intraoperatively. Results We found that men (odds ratio, OR = 5.6; p = 0.004, patients with Charnley class C (OR = 6.71; p = 0.013, those having more severe acetabular bone defects (OR = 4 for each degree of severity; p = 0.002, and longer time to revision surgery (OR = 1.51 for each additional year; p = 0.012 had a greater chance of aseptic loosening of the cup. However, aseptic loosening was not directly predicted by polyethylene wear rate in our patients. Conclusion Severity of bone defects predicts the risk for aseptic loosening in ABG I cup. Factors potentially associated with the quality of bone bed and biomechanics of the hip might influence on the risk of aseptic loosening in this implant.

    The discrimination of sex is central to the process of establishing a personal identification from human skeletal remains. Previous study has demonstrated that osteometric analysis of the sternal extremity of the fourth rib provides a reasonably accurate method for assessing this biological attribute in diverse human groups. As metric standards are generally population-specific, the purpose of the current research was to evaluate the degree of sexual dimorphism present in the fourth rib among contemporary Spaniards, a group thus far not investigated, and generate discriminant function equations which can be used to estimate the sex of unidentified remains in this population. Superior-inferior height and anterior-posterior breadth dimensions of the fourth rib were collected for a sample consisting of 60 males and 57 females derived from postmortem examinations performed at the Institute of Legal Medicine, Seville, Spain. The results demonstrated that both rib dimensions were highly sexually dimorphic (pclassification rates of 76.9% and 83.8% for breadth and height dimensions, respectively. Multivariate analysis incorporating both rib measurements improved the allocation accuracy to 86.3%, with an associated sex bias of only 0.7%. Therefore, the derived discriminant function equations, particularly those that incorporate rib height, can be effectively used in cases involving fragmentary remains in which more dimorphic elements such as the pelvis are not preserved, as well as complete skeletons to complement other metric and morphological sex assessment methods.

    The geophilomorph centipede, Himantarium gabrielis, when disturbed, discharges a viscous and proteinaceous secretion from the sternal glands. This exudate was found by gas chromatography-mass spectrometry, liquid chromatography-high resolution mass spectrometry, liquid chromatography-mass spectrometry-mass spectrometry and NMR analyses to be composed of hydrogen cyanide, benzaldehyde, benzoyl nitrile, benzyl nitrile, mandelonitrile, mandelonitrile benzoate, 3,7,6 O-trimethylguanine (himantarine), farnesyl 2,3-dihydrofarnesoate and farnesyl farnesoate. This is the first report on the presence of benzyl nitrile and mandelonitrile benzoate in secreted substances from centipedes. Farnesyl 2,3-dihydrofarnesoate is a new compound, while himantarine and farnesyl farnesoate were not known as natural products. A post-secretion release of hydrogen cyanide by reaction of mandelonitrile and benzoyl nitrile was observed by NMR, and hydrogen cyanide signals were completely assigned. In addition, a protein component of the secretion was analysed by electrophoresis which revealed the presence of a major 55 kDa protein. Analyses of the defensive exudates of other geophilomorph families should produce further chemical surprises.

    Full Text Available Human enteroviruses (EV cause a wide spectrum of both common and uncommon illnesses among all age groups. Enterically transmitted. The objective of this study was to identify non-poliovirus EV as a cause of viral aseptic meningitis (VAM by two methods (cell culture and Real time PCR. From October 2010 to August 2011 cerebrospinal fluid (CSF samples were collected from 85 patients Embaba fever hospital admitted with symptoms of aseptic meningitis of any age and both sexes. The 85 CSF samples were inoculated into RD (human rhabdomyosarcoma cell line in three blind passages to amplify isolates producing EV-like CPE. A total of 14 (16.5% out of 85 CSF samples showed EV-like CPE. By Real time PCR 11 out of the 14 culture positive samples and 5 out of the 14 source of virus isolation original CSF were non polio EV positive. The frequency of non-polio EV meningitis hospital admissions was in the summer season (50%, spring (25%, late autumn (16.6% and least frequency in winter (8.4%. non-polio EV meningitis was detected in 6 out of 41 male patients (14.5% and in 6 out of 44 female patients (13.5%. Also non-polio EV meningitis was detected in all ages with marked increase of incidence in young children (41.6% and old age (50% and less in adult (8.4%. . In conclusionOur data showed that the non-polioviruses EV was associated with the majority of VAM during 2010 – 2011 at the Embaba fever hospital which serves Embaba, Shoubra Elkheema, Qualyba and neighbors localities in Egypt. Rapid detection of non-polio EV meningitis is essential for making decisions about patient management and treatment

    Mars Organic Molecule Analyzer (MOMA) is an instrument suite on the ESA ExoMars 2018 Rover, and the Mass Spectrometer (MOMA-MS) is being built at Goddard Space Flight Center (GSFC). As MOMA-MS is a life-detection instrument and it thus falls in the most stringent category of Planetary Protection (PP) biological cleanliness requirements. Less than 0.03 sporem2 is allowed in the instrument sample path. In order to meet these PP requirements, MOMA-MS must be built and maintained in a low bioburden environment. The MOMA-MS project at GSFC maintains three cleanrooms with varying levels of bioburden control. The Aseptic Assembly Cleanroom has the highest level of control, applying three different bioburden reducing methods: 70 IPA, 7.5 Hydrogen Peroxide, and Ultra-Violet C light. The three methods are used in rotation and each kills microbes by a different mechanism, reducing the likelihood of microorganisms developing resistance to all three. The Integration and Mars Chamber Cleanrooms use less biocidal cleaning, with the option to deploy extra techniques as necessary. To support the monitoring of cleanrooms and verification that MOMA-MS hardware meets PP requirements, a new Planetary Protection lab was established that currently has the capabilities of standard growth assays for spore or vegetative bacteria, rapid bioburden analysis that detects Adenosine Triphosphate (ATP), plus autoclave and DHMR verification. The cleanrooms are monitored both for vegetative microorganisms and by rapid ATP assay, and a clear difference in bioburden is observed between the aseptic the other cleanroom.

    The study evaluates the clinical significance of CXCL13 (leukocyte chemoattractant synthesized in CSF ) in Lyme neuroborreliosis (LNB) and other aseptic CNS infections. 244 patients with symptoms of neuroinfection and/or LNB were divided into groups: A - patients with LNB-positive antibodies in serum and CSF (96) or CSF only (14); B - patients with aseptic non-borrelial neuroinfections (82); C - negative controls (52). Group A was divided into A1-A4 according to pleocytosis in CSF and AIIgG positivity. The highest CSF CXCL13 concentrations (max. 81,287.60pg/ml; median 1766.90pg/ml) were in A1 (positive AI, pleocytosis) and A3 (negative AIIgG, pleocytosis; max. 7201,60pg/ml, median 56.22pg/ml). A2 (positive AI without pleocytosis) and A4 (negative AI without pleocytosis) had low CXCL13 levels - A2 max. 650.50pg/ml (median<7.80pg/ml); A4 max. 118.56pg/ml (median<7.8pg/ml). In B the median was 28.10pg/ml (max. 595.87pg/ml). In C the CXCL13 concentrations were the lowest (max. 83.83pg/ml; median<7.80pg/ml). The lowest cut-off was 29pg/ml (sensitivity 90.0%, specificity 72.2%), the highest one 400pg/ml (sensitivity 59.6%, specificity 94.0%). The group differences of serum CXCL13 were insignificant. The highest concentrations were at the beginning of the disease. In LNB CXCL13 correlates better with the CSF pleocytosis than AI positivity.

    Aseptic osteonecrosis causes various clinical manifestations, depending on its location, but has in common a histopathological and radiological substrate. Aseptic osteonecrosis of the femoral head is a condition whose pathogenesis remains unclear despite many theories developed so far, and the discovery of numerous risk factors. The objective of this study is to emphasize the role of imaging techniques and correlating histology and immunohistochemistry methods in order to more accurately stage the disease. This retrospective study was performed on a total of 103 patients with clinical and radiological suspicion of unilateral or bilateral osteonecrosis. For the diagnosis criteria, we used clinical information, pelvic X-ray images, magnetic resonance imaging (MRI) or computed tomography (CT). For the inclusion of patients in a disease stage, we used the Association Research Circulation Osseous (ARCO) classification system. For patients diagnosed at an advanced stage, who underwent hip arthroplasty, we harvested biological material necessary for the histopathological study. There were differences in the appearance and extent of the lesion on the histological samples compared to macroscopic examination and even those obtained through imaging means, particularly for patients in evolutionary stage III. Aspects such as the extension of the area of fibrosis, bone tissue remodeling, the density of the newly formed vascular network and degree of impairment of the cartilage, are determined more accurately using histology and immunohistochemistry techniques. Before classifying patients in a certain stage, after correlating clinical and imaging data, histopathological aspects have to be considered, particularly in patients in stages III and IV, in which total hip arthroplasty could be delayed.

    Aseptic necrosis of the femoral head is a condition caused by partial or total interruption of blood supply to the femoral head. The diminished blood supply causes necrosis of the cellular elements and of the bone marrow, followed by the collapse of the bone structure, events that ultimately lead to the destruction of the bone tissue, the appearance of local pain and loss of function in the affected coxofemoral joint. The importance of this condition is that it mainly affects young adults aged 30-50 years, active from a socio-professional standpoint, and increased life expectancy. The material studied to achieve CD68 immunostaining was represented by bone fragments from the area of necrosis and from the adjacent areas of the femoral heads, harvested from 39 patients when performing hip arthroplasty surgery. The patients were diagnosed with aseptic necrosis of the femoral head and hospitalized in the Clinic of Orthopedics and Traumatology, Emergency County Hospital of Craiova, Romania, from June 2014 to January 2015. The 39 patients included in the study were divided into four categories according to presented risk factors (alcohol, alcohol and smoking, trauma, corticosteroids). All the 39 cases had positive immunostaining for CD68, macrophage being highlighted both in the area of necrosis and in the adjacent areas. We noted significant differences in the number and arrangement of macrophages in patients presenting different risk factors. The highest number of macrophages was present in patients presenting a risk factor corticosteroids, and the lowest number of macrophages was found in patients who had trauma as the main risk factor.

    Full Text Available Abstract Background Sternal wound infection (SWI is an uncommon but potentially life-threatening complication of cardiac surgery. Predisposing factors for SWI are multiple with varied frequencies in different studies. The purpose of this study was to assess the incidence, risk factors, and mortality of SWI after coronary artery bypass grafting (CABG at Tehran Heart Center. Methods This study prospectively evaluated multiple risk factors for SWI in 9201 patients who underwent CABG at Tehran Heart Center between January 2002 and February 2006. Cases of SWI were confirmed based on the criteria of the Centers for Disease Control and Prevention. Deep SWI (bone and mediastinitis was categorized according to the Oakley classification. Results In the study period, 9201 CABGs were performed with a total SWI rate of 0.47 percent (44 cases and deep SWI of 0.22 percent (21 cases. Perioperative (in-hospital mortality was 9.1% for total SWI and about 14% for deep SWI versus 1.1% for non-SWI CABG patients. Female gender, preoperative hypertension, high functional class, diabetes mellitus, obesity, prolonged intubation time (more than 48 h, and re-exploration for bleeding were significant risk factors for developing SWI (p = 0.05 in univariate analysis. In multivariate analysis, hypertension (OR = 10.7, re-exploration (OR = 13.4, and female gender (OR = 2.7 were identified as significant predictors of SWI (p Conclusion Rarely reported previously, the two risk factors of hypertension and the female gender were significant risk factors in our study. Conversely, some other risk factors such as cigarette smoking and age mentioned as significant in other reports were not significant in our study. Further studies are needed for better documentation.

    International Nuclear Information System (INIS)

    Purpose: The study aimed at MRI evaluation of aseptic osteonecrosis (AON) in children over the course of hyperbaric oxygen (HBO) therapy. Material and methods: Retrospective analysis of 72 MRI studies in 20 children presenting with AON during chemotherapy. Two groups were differentiated: Gr. I (n=8) was treated exclusively with relief of weightbearing structures, Gr. II (n=12) was additionally treated with HBO therapy. The MRI examinations were evaluated by a point-score system (1-6 points) by two radiologists. Results: Gr. II initially showed more severe findings (average score: 3.4) in comparison to Gr. I (average score: 2.65). During the follow-up time period the average scores rose to 3.2 score-points in Gr. I and 4.1 points in Gr. II. No statistically significant difference was evident between the two groups in the course of AON. Conclusion: The majority of chemotherapy associated AON which initially present with advanced findings show a progression in MRI over their further course. HBO therapy in addition to the relief of affected weightbearing structures statistically shows no significant improvement in MRI morphology during the course of the treatment. (orig.)

Rapid clonal micropropagation protocol for large-scale multiplication of an endemic medicinal plant Soymida febrifuga (Meliaceae was established from 15-day aseptic seedling cotyledonary node and shoot tip explants. High frequency of sprouting and shoot differentiation was observed from cotyledonary node explants compared to shoot tip, on Murashige and Skoog (MS medium fortified with BA, KN, 2-iP and CM. Of the cytokinins used, BA (3.0 mgl-1 supported highest average number and maximum multiple shoot differentiation (16.6. In vitro proliferated shoots were multiplied rapidly by culturing nodal segments as microcuttings, further subcultured on the same media for elongation. Elongated shoots upon transfer to MS medium fortified with IBA showed rooting within two weeks of culture. Rooted plantlets were successfully hardened and 75% of rooted shoots successfully survived on establishment to the soil. Plants looked healthy with no visually detectable phenotypic variations. This protocol provides a successful and rapid technique that can be used for ex situ conservation minimizing the pressure on wild populations and contributes to the conservation of this endemic medicinally potent flora.

    In Poland, a surveillance system capturing generic information on both diagnosed and undiagnosed aseptic central nervous system infections (ACI) has been in operation since 1966. This study evaluates to what extent the ACI surveillance is able to meet its objectives to monitor ACI trends and to detect signals of public health importance such as enteroviral outbreaks, tick-borne encephalitis (TBE) endemic foci, poliovirus appearance or emergence of new neurotropic viruses. Between 2004 and 2008, aetiology was established for 17% of ACI cases. Of the 1,994 reported ACI cases, 232 (11.6%) were diagnosed with TBE virus, 46 (2.3%) with enterovirus, 35 (1.8%) with herpesvirus, and 32 (1.6%) had other viral causes such as Epstein Barr virus or adenovirus. The system's performance varied between the provinces, with the frequency of suspected ACI cases referred for viral aetiology investigation in 2008 ranging from 1.98 to 285.4 samples per million inhabitants. The sensitivity of physicians' reporting, estimated as the proportion of hospitalised ACI cases reported to the surveillance system, was 48% nationally, with vast regional differences (range 30–91%). To conclude, the ACI surveillance system in Poland does currently not meet its objectives, due to limited availability of aetiological diagnosis and microbiological confirmation and to regional differences in reporting sensitivity.

    Full Text Available Ahmad K Abou-Foul, Thajunisha M Buhary, Sedki L Gayed Department of Genitourinary Medicine, Royal Blackburn Hospital, East Lancashire Hospitals NHS Trust, Blackburn, UK Introduction: Cases of idiopathic recurrent benign aseptic meningitis were first described by Mollaret. Today, herpes simplex virus (HSV is considered the cause of most cases of Mollaret's meningitis. Case report: A 40-year-old male was referred to our genitourinary medicine clinic with recurrent genital herpetic lesions. He had HSV-2-positive genital ulcers 8 years earlier. One year after the first infection, he developed severe recurrent attacks of headache associated with meningitis symptoms. The results of all radiological and biochemical tests were normal, but the patient reported a correlation between his attacks and genital herpes flare-ups. We diagnosed the patient with Mollaret's meningitis and started him on continuous suppressive acyclovir therapy, which resulted in marked clinical improvement. Discussion: Mollaret's meningitis is a rare form of idiopathic recurrent aseptic meningitis that has a sudden onset, short duration, and spontaneous remission with unpredictable recurrence. We believe that the presence of concurrent or recurrent mucocutaneous herpetic lesions can aid its diagnosis, prior to which, affected patients usually have many unnecessary investigations and treatments. Therefore, detailed sexual history should be sought in all patients with aseptic meningitis, and clinicians should also ask about history of recurrent headaches in all patients with recurrent herpetic anogenital lesions. Continuous suppressive acyclovir therapy may reduce the frequency and severity of attacks and can dramatically improve lifestyle.

    Investigators of our research facility generally accept the concept of asepsis as an important component of adequate surgical care for animals. However, they experience difficulties putting it into practice, especially in the case of rodents. The reasons for this are inconvenience, cost, and lack of training. To better assist investigators in the implementation of aseptic surgical techniques in their laboratories, we have created an Operating Room (OR) Committee modeled after OR committees found in human hospitals. A reconstructive surgeon, a veterinarian, a research scientist, a nurse involved in the training of OR personnel, interns, graduate students, and an animal health technician were chosen as committee members in light of their OR and animal care expertise. The first task of the OR Committee was to establish institutional guidelines for aseptic surgery, taking into account the costs imposed on research budgets by these procedures. The OR Committee also supports a complete training program in aseptic surgery techniques, which consists of lectures, a training manual, videos, and a practical course. Furthermore, when experimental procedures require specialized equipment, the OR Committee collaborates with researchers to develop strategies to achieve asepsis. This OR Committee and the training program proved to be important tools to promote and improve the quality of animal care during surgery.

  4. Successful human infection with P. falciparum using three aseptic Anopheles stephensi mosquitoes: a new model for controlled human malaria infection.

    Matthew B Laurens

    Full Text Available Controlled human malaria infection (CHMI is a powerful method for assessing the efficacy of anti-malaria vaccines and drugs targeting pre-erythrocytic and erythrocytic stages of the parasite. CHMI has heretofore required the bites of 5 Plasmodium falciparum (Pf sporozoite (SPZ-infected mosquitoes to reliably induce Pf malaria. We reported that CHMI using the bites of 3 PfSPZ-infected mosquitoes reared aseptically in compliance with current good manufacturing practices (cGMP was successful in 6 participants. Here, we report results from a subsequent CHMI study using 3 PfSPZ-infected mosquitoes reared aseptically to validate the initial clinical trial. We also compare results of safety, tolerability, and transmission dynamics in participants undergoing CHMI using 3 PfSPZ-infected mosquitoes reared aseptically to published studies of CHMI using 5 mosquitoes. Nineteen adults aged 18-40 years were bitten by 3 Anopheles stephensi mosquitoes infected with the chloroquine-sensitive NF54 strain of Pf. All 19 participants developed malaria (100%; 12 of 19 (63% on Day 11. The mean pre-patent period was 258.3 hours (range 210.5-333.8. The geometric mean parasitemia at first diagnosis by microscopy was 9.5 parasites/µL (range 2-44. Quantitative polymerase chain reaction (qPCR detected parasites an average of 79.8 hours (range 43.8-116.7 before microscopy. The mosquitoes had a geometric mean of 37,894 PfSPZ/mosquito (range 3,500-152,200. Exposure to the bites of 3 aseptically-raised, PfSPZ-infected mosquitoes is a safe, effective procedure for CHMI in malaria-naïve adults. The aseptic model should be considered as a new standard for CHMI trials in non-endemic areas. Microscopy is the gold standard used for the diagnosis of Pf malaria after CHMI, but qPCR identifies parasites earlier. If qPCR continues to be shown to be highly specific, and can be made to be practical, rapid, and standardized, it should be considered as an alternative for diagnosis

    Tissue engineering chamber (TEC) makes it possible to generate significant amounts of mature, vascularized, stable, and transferable adipose tissue. However, little is known about the role of the chamber in tissue engineering. Therefore, to investigate the role of inflammatory response and the change in mechanotransduction started by TEC after implantation, we placed a unique TEC model on the surface of the groin fat pads in rats to study the expression of cytokines and tissue development in the TEC. The number of infiltrating cells was counted, and vascular endothelial growth factor (VEGF) and monocyte chemotactic protein-1 (MCP-1) expression levels in the chamber at multiple time points postimplantation were analyzed by enzyme-linked immunosorbent assay. Tissue samples were collected at various time points and labeled for specific cell populations. The result showed that new adipose tissue formed in the chamber at day 60. Also, the expression of MCP-1 and VEGF in the chamber decreased slightly from an early stage as well as the number of the infiltrating cells. A large number of CD34+/perilipin- perivascular cells could be detected at day 30. Also, the CD34+/perilipin+ adipose precursor cell numbers increased sharply by day 45 and then decreased by day 60. CD34-/perilipin+ mature adipocytes were hard to detect in the chamber content at day 30, but their number increased and then peaked at day 60. Ki67-positive cells could be found near blood vessels and their number decreased sharply over time. Masson's trichrome showed that collagen was the dominant component of the chamber content at early stage and was replaced by newly formed small adipocytes over time. Our findings suggested that the TEC implantation could promote the proliferation of adipose precursor cells derived from local adipose tissue, increase angiogenesis, and finally lead to spontaneous adipogenesis by inducing aseptic inflammation and changing local mechanotransduction.

    Experiments were performed in order to determine the microbicidal effect of ultraviolet irradiation using a high intensity uv lamp recently developed by BBC, Baden (Switzerland). Conidiae of molds, Bacillus spores, and vegetative cells of yeasts were killed within a few seconds. The germicidal effect of uv rays upon B. subtilis spores was further studied in dependence of the distance from the uv lamp, the angle of inclination of the irradiated plane, and the humidity of air. The efficiency of the tested uv lamp seems to be sufficient for its use in aseptic plants provided that the irradiated packaging materials are smooth, uv-resistant, and rather free of dust particles.

    With the development of chemotherapy, imaging, surgical techniques and material science, limb-salvage has become a widely accepted concept in the treatment of bone and soft tissue tumors. Prosthetic reconstruction after tumor segment resection has become a common operation method. In the history, there appeared many kinds of materials for the reconstruction after the resection of tumors. The megaprosthesis has a history of more than 60 years, and has become the mainstream now, with many advantages over the other reconstruction materials. The aseptic loosening of megaprotheses is a common postoperative complication and also a prominent cause of prosthesis failure. How high is the aseptic loosening rate? Will the rate be affected by such factors as the patient’s age, gender, disease category, implantation site, reconstruction length, chemotherapy and so on? Will the rate be obviously reduced due to the improvement of megaprotheses? These questions are worth researching. The aseptic loosening rate of megaprostheses and related factors are reviewed in this article based on previous studies. According to previous reports, many factors concerning the patient and the prosthesis have an impact on the aseptic loosening rate. The clear and deifnite related factors included the implantation site, porous coating in the collar, type of articulation, age at the time of surgery and reconstruction length, and the gender and disease category are irrelevant factors. As to the size of intramedullary stem, ifxation mode, modular/custom and chemotherapy, their correlation with the aseptic loosening rate is still unclear.

    2009-10-01

    Full Text Available Echovirus 30 belongs to the genus Enterovirus and is widely associated with aseptic meningitis (AM outbreaks. In Brazil epidemics due to this serotype were reported in several states but in Rio de Janeiro, before this study, it was only involved in sporadic episodes. We retrospectively collected data from AM notifications charts and enterovirus isolation database from Rio de Janeiro State Health Department (RJSHD and Enterovirus Reference Laboratory in the year of 2005. An outbreak of AM was detected during March, April and May associated with a high cell culture isolation rate for echovirus 30 (17.4%. Male children with ages varying from 1 to 9 years were more affected. Of the 22 patients with confirmed echovirus 30 disease, clinical information was available in eight; fever, headache and vomiting were the most common manifestations. CSF analysis showed a typical pattern of viral infection with median of cellularity of 100 cells/mm³ and mononuclear cell predominance in 64.7% of the cases. The median of protein and glucose levels of 49 mg/dL and 56.5 mg/dL. The fatality rate was null. Despite its benign course and the lack of treatment options, aseptic meningitis surveillance is crucial for early identification of causative agents of outbreaks, which helps to avoid additional testing and inappropriate use of antimicrobials.

    Full Text Available Abstract Background An outbreak of aseptic meningitis occurred in Tianshui city of Gansu Province, the People's Republic of China, from March to June 2005. A total of 85 patients were clinical confirmed as aseptic meningitis in this outbreak. Results CVA9 was mainly responsible for this outbreak supported by the clinical manifestations of the patients, epidemiological data of the outbreak, the results of RT-PCR and complete VP1 sequence determination, conventional neutralization assays, IgM serological assays, viral isolation and phylogenetics analysis. Through phylogenetic analysis and homogeneity analysis for partial VP1 gene, the nucleotide and amino acid homologies between Gansu isolates and former Chinese CVA9 strains were 88.2%-96.1% and 97.2%-99.2%, respectively. Multiple transmission chains of CVA9 occurred in different provinces or years in China. Moreover, in order to clarify the genotype of CVA9, Gansu CVA9 strains isolated in this outbreak were compared with other CVA9 isolates based on VP1/2A junction regions (genotyping region and they might belong to a new genotype of CVA9, which could be assigned for genotype XIII, Conclusions CVA9 was confirmed as the pathogen responsible for this outbreak. The phylogenetic analysis indicated that the CVA9 strains isolated in this outbreak might belong to a new genotype.

    To quantify whether injected cement volumes differed between two groups of patients who underwent experimental minimally invasive percutaneous cement injection procedures to stabilize aseptically loose hip prostheses. One patient group was preoperatively treated using gene-directed enzyme prodrug therapy to remove fibrous interface tissue, while the other group received no preoperative treatment. It was hypothesized that cement penetration may have been inhibited by the presence of fibrous interface tissue in periprosthetic lesions. We analyzed 17 patients (14 female, 3 male, ages 72-91, ASA categories 2-4) who were treated at our institution. Osteolytic lesions and injected cement were manually delineated using 3D CT image segmentation, and the deposition of injected cement was quantified. Patients who underwent preoperative gene-directed enzyme therapy to remove fibrous tissue exhibited larger injected cement volumes than those who did not. The observed median increase in injected cement volume was 6.8 ml. Higher cement leakage volumes were also observed for this group. We conclude that prior removal of periprosthetic fibrous interface tissue may enable better cement flow and penetration. This might lead to better refixation of aseptically loosened prostheses.

    Surface sterilization of explant is an important and most sensitive step in plant tissue culture. Inappropriate concentrations of sterilants have lethal effect in cell division and it restricts growth and development of explant. Therefore, suitable concentration, combinations and duration of exposure of sterilant is essential to raise in vitro cultures successfully. This data demonstrates use of various sterilizing agents for aseptic plantlet germination from seed of Carissa carandas (Apocynaceae). The present dataset provides information in support of cost-effective explant sterilization potential of benzalkonium chloride containing commercial bleach (Lizol) and its comparison with traditionally used surface sterilants in plant tissue culture i.e. 0.1% HgCl2 alone and in combination with 70% alcohol. The data on callogenic response using MS medium supplemented with plant growth regulators is also shared. PMID:27222851

    A handheld sensor system for the online measurement of hydrogen peroxide (H{sub 2}O{sub 2}) in aseptic sterilisation processes has been developed. It is based on a calorimetric-type gas sensor that consists of a differential set-up of two temperature sensors, of which one is catalytically activated and the second one is passivated and used as reference. The sensor principle relies in detecting a rise in temperature on the active sensor due to the exothermic reaction of H{sub 2}O{sub 2} on the catalytic surface. To characterise the sensor system towards H{sub 2}O{sub 2} sensitivity and other influencing factors, measurements have been carried out both at an experimental set-up and a manufacturer's sterilisation machine. Physical sensor characterisation was done by means of the optical microscopy. (Abstract Copyright [2010], Wiley Periodicals, Inc.)

    Metal implants are essential therapeutic tools for the treatment of bone fractures and joint replacements. The metals and metal alloys used in contemporary orthopedic and trauma surgery are well tolerated by the majority of patients. However, complications resulting from inflammatory and immune reactions to metal implants have been well documented. This review briefly discusses the different mechanisms of metal implant corrosion in the human body, which lead to the release of significant levels of metal ions into the peri-implant tissues and the systemic blood circulation. Additionally, this article reviews the effects of the released ions on bone metabolism and the immune system and discusses their involvement in the pathophysiological mechanisms of aseptic loosening and metal hypersensitivity in patients with metal implants.

    Full Text Available Aim. To evaluate whether aseptic hypertrophic nonunion in the long bones of the lower extremity can be treated successfully with LISS applied with closed methods without grafting. Materials and Methods. The study included 7 tibias and 9 femurs of 16 patients. All cases had hypertrophic nonunion. Initial surgical treatment was with intramedullary nailing in 14 cases, 6 of which had required an exchange of intramedullary nail. All the patients were treated with LISS plate with closed methods. Results. Union was obtained at mean 7 months in all patients. No implant loosening or breakage of the implant was observed and there was no requirement for secondary surgery. Conclusion. Cases of hypertrophic nonunion have excellent blood supply and biological potential. Therefore, there is no need for bone grafting and the addition of fracture stability is enough to achieve full union. Using a limited approach and percutaneous screw insertion, LISS provides fracture stabilization with soft tissue protection.

    Coxsackievirus B3 (CV-B3) has frequently been associated with aseptic meningitis outbreaks in China. To identify sequence motifs related to aseptic meningitis and to construct an infectious clone, the genome sequence of 08TC170, a representative strain isolated from cerebrospinal fluid (CSF) samples from an outbreak in Shandong in 2008, was determined, and the coding regions for P1-P3 and VP1 were aligned. The first 21 and last 20 residues were "TTAAAACAGCCTGTGGGTTGT" and "ATTCTCCGCATTCGGTGCGG", respectively. The whole genome consisted of 7401 nucleotides, sharing 80.8 % identity with the prototype strain Nancy and low sequence similarity with members of clusters A-C. In contrast, 08TC170 showed high sequence similarity to members of cluster D. An especially high level of sequence identity (≥97.7 %) was found within a branch constituted by 08TC170 and four Chinese strains that clustered together in all of the P1-P3 phylogenic trees. In addition, 08TC170 also possessed a close relationship to the Hong Kong strain 26362/08 in VP1. Similarity plot analysis showed that 08TC170 was most similar to the Chinese CV-B3 strain SSM in P1 and the partial P2 coding region but to the CV-B5 or E-6 strain in 2C and following regions. A T277A mutation was found in 08TC170 and other strains isolated in 2008-2010, but not in strains isolated before 2008, which had high sequence similarity and formed the cluster A277. The results suggested that 08TC170 was the product of both intertypic recombination and point mutation, whose effects on viral neurovirulence will be investigated in a further study. The high homology between 08TC170 and other strains revealed their co-circulation in mainland China and Hong Kong and indicates that further surveillance is needed. PMID:27236460

    Full Text Available The aseptic meningitis after Measles-Mumps-Rubella vaccine (MMR is a well recognized complication, and different incidences have been observed in several studies. We retrospectively analyzed forty cases of aseptic meningitis, during a large public immunization campaign (1998 in Curitiba, Southern Brazil (590,609 people, admitted in our Service. The vaccine utilized was Leningrad-3-Zagreb mumps strain, Edmonston-Zagreb measles strain, and RA 27#3 rubella strain. In all county, a total number of 87 cases were reported, resulting in a incidence of 1.7 cases per 10,000 given doses . The mean age was 23.7 ± 12.8 years. The female:male ratio was 1.35:1. Severe headache with meningismus (92.5%, fever (87.5%, nausea/vomiting (82.5% were the most common clinical findings. Three cases (7.5% developed mild mumps. All patients underwent cerebrospinal fluid (CSF tap with the following findings: mononuclear pleocytosis from 100 to 500 cells/mm³ in 17 cases (42.5%; 257.5 ± 260.6 cells/mm³; increased protein 28 cases (67.5%; 92.1 ± 76.9 mg/dL; glucose was normal in all cases (56.8 ± 11.2 mg/dL except in 4 (10% cases, which presented less than 44 mg/dL. All serological tests (latex to bacterial meningitis, Cryptococcus, cysticercosis, VDRL and bacteriological cultures were negative. Virus identification were also negative in 8 samples. None of the patients had neurological deficits or related symptoms after one year of onset. We believe the benefit of vaccination clearly outweights the incidence of benign vaccine-associated meningitis.

    Full Text Available BACKGROUND: Experimental infection of malaria-naïve volunteers by the bite of Plasmodium falciparum-infected mosquitoes is a preferred means to test the protective effect of malaria vaccines and drugs. The standard model relies on the bite of five infected mosquitoes to induce malaria. We examined the efficacy of malaria transmission using mosquitoes raised aseptically in compliance with current Good Manufacturing Practices (cGMPs. METHODS AND FINDINGS: Eighteen adults aged 18-40 years were randomized to receive 1, 3 or 5 bites of Anopheles stephensi mosquitoes infected with the chloroquine-sensitive NF54 strain of P. falciparum. Seventeen participants developed malaria; fourteen occurring on Day 11. The mean prepatent period was 10.9 days (9-12 days. The geometric mean parasitemia was 15.7 parasites/µL (range: 4-70 by microscopy. Polymerase chain reaction (PCR detected parasites 3.1 (range: 0-4 days prior to microscopy. The geometric mean sporozoite load was 16,753 sporozoites per infected mosquito (range: 1,000-57,500. A 1-bite participant withdrew from the study on Day 13 post-challenge and was PCR and smear negative. CONCLUSIONS: The use of aseptic, cGMP-compliant P. falciparum-infected mosquitoes is safe, is associated with a precise prepatent period compared to the standard model and appears more efficient than the standard approach, as it led to infection in 100% (6/6 of volunteers exposed to three mosquito bites and 83% (5/6 of volunteers exposed to one mosquito bite.

    In the treatment of tissue wounds practically all the time there is necessary the establishment of aseptic conditions in the area of the damaged tissue. In modern medical practice quite a while the use of materials on the basis of collagen aroused widespread. The aim of the study was an assessment the bacteriostatic properties both of collagenic substance with the antibiotics immobilized on it, and ions of silver also. The presence on a surface of collagen of a large number of active functional groups allow to use it as a matrix for an immobilization of various biologically active and medicinal agents. Authors performed an assessment of possibility of an immobilization of antibiotics on the collagenic carrier. The purpose of an immobilization was in the prolongation of the impact of an active component--Polymyxin-M or Gentamycin. Besides aseptic effect, availability of specific amino acids of collagen will promote the acceleration of the reparative processes in a wound. There were performed investigations on determination of bacteriostatic effect of immobilized on the protein carrier (collagen of hydrobionts) antibiotics, and silver ions also. Bacteriostatic effect was estimated by the disco--a diffusive method with use of E. coli as test culture. Results of the studies showed that the delivered preparation had bacteriostatic effect on the test culture. At that the area of a zone of a growth inhibition in case of the of use--Polymyxin was 1.3 time more than, than in case of the use of a preparation of Gentamycin. The obtained collagenic substances of an origin with the immobilized bacteriostatic components and ions of silver have considerable prospects and real opportunity in the delivery of aseptic preparations of a domestic production. Taking into account the available data in further there is planned the development of aseptic preparations with the occluded biologically active agents and nanoparticles of metals for providing an aseptics and acceleration the

    Full Text Available Background. Modern conceptions about mechanisms of inflammation of the small intestine could not be formed without an understanding of intercellular relationships that are realized by biologically active signaling molecules produced by endocrine cells. Methods. The experimental study has been carried out on the small intestine extracted from 140 adult male rats. Electron and light microscopy methods were used. Acute aseptic inflammation was modeled by intraperitoneal carrageenan injection; influence of subcutaneously cryopreserved placenta injection was analyzed. Results. After modeling of the acute aseptic peritoneal inflammation the maximal increase of ECL-cells was noted on the 21st day. The slowest restoration of endocrine cells number occurred on all measured parameters and was observed on day 30th of the observation. In case of administration of cryopreserved placenta at the early stages (days 3rd – 7th the increase of average number of EC- and ECL-cells promoted the enhanced permeability of vessels in the lamina propria. The decrease in number of P-cells prevented the development of hyperacid gastritis. Reduction in the average number of D1- cells prevented the excessive vasodilatation and facilitated the excretion of excess fluid from the foci of inflammation. In simultaneous subcutaneous administration of cryopreserved placenta and modeling of acute aseptic peritoneal inflammation the number of ЕС- and ЕСL-cells increased, accelerating the vascular response to inflammation. Conclusion. Active appearance of low-differentiated cells including those with “shapes of mitosis” on the day 14th indicates restoration of structural components of the small intestine mucosa and processes of absorption and parietal digestion after placenta administration during acute aseptic inflammation.

    Pyrolysis of aseptic packages (tetrapak cartons) in a laboratory apparatus using a flow screw type reactor and a secondary catalytic reactor for tar cracking was studied. The pyrolysis experiments were realized at temperatures ranging from 650 °C to 850 °C aimed at maximizing of the amount of the gas product and reducing its tar content. Distribution of tetrapak into the product yields at different conditions was obtained. The presence of H2, CO, CH4, CO2 and light hydrocarbons, HCx, in the gas product was observed. The Aluminum foil was easily separated from the solid product. The rest part of char was characterized by proximate and elemental analysis and calorimetric measurements. The total organic carbon in the tar product was estimated by elemental analysis of tars. Two types of catalysts (dolomite and red clay marked AFRC) were used for catalytic thermal tar decomposition. Three series of experiments (without catalyst in a secondary cracking reactor, with dolomite and with AFRC) at temperatures of 650, 700, 750, 800 and 850 °C were carried out. Both types of catalysts have significantly affected the content of tars and other components in pyrolytic gases. The effect of catalyst on the tetrapack distribution into the product yield on the composition of gas and on the total organic carbon in the tar product is presented in this work. PMID:23428565

    An acromioclavicular joint cyst is an uncommonly reported condition, which seems to result from a massive rotator cuff tear and degenerative osteoarthritis of the acromioclavicular joint. We present the case of an 81-year-old man affected by an acromioclavicular joint cyst, associated to a massive rotator cuff tear, proximal migration of the humeral head and osteoarthritis of the gleno-humeral joint. The mass was 7 x 2.5 cm in size and the overlying skin presented a fistula that drained clear synovial-like fluid. Plain X-ray examination of the left shoulder showed proximal migration of the humeral head migration and osteoarthritis of the gleno-humeral joint, and further MRI evaluation confirmed the clinical diagnosis of a complete rotator cuff tear and observed a large subcutaneous cyst in communication with the degenerative acromioclavicular joint. The patient underwent surgical excision of the cyst and lateral resection of the clavicle to prevent disease recurrence. To the best of our knowledge, this is the first reported case of an acromioclavicular joint cyst complicated by an aseptic fistula resulting from multiple aspirations. PMID:19918423

    In premises for blood conservation, production of dry human plasma and infusion solutions "notwithstanding the permanent measures for desinfection, new bacterial contamination occurs from time to time and whose source are the casings and material originating from non-sterile environment. Bacteriological control, which has primarily a preventive character, enables a due forecast for measures to be undertaken by the appropriate desinfection of the working surfaces and air, satisfactory conditions of aseptic work can be maintained. General hygiene should be paid attention to as well as mechanical cleansing of premises, avoidance of groups for lunch-time etc., since the treatment by desinfectors would not be sufficient for maintenance of aseptic working conditions. In order to prevent the transmission of bacterial contamination, premises for blood conservation should be strictly separated from other operations and also prevent the unnecessary movements of personnel through corridors. The results of the bacteriological control of the personnel show that greater attention should be paid to their health care since the workers there work in closed aseptic systems and thus avoid them as a bacteria transmittors in respect to danger of blood and dry human plasma contamination. It is also necessary to efficiently educate the personnel for work in aseptic conditions and also increase their elementary knowledge from bacteriology and hygiene. The bacterial skin-flora on the spot of donor's venepuncture also presents a certain danger for blood contamination. Therefore, it is necessary to establish the most optimal manner of skin desinfecate together with the most appropriate means having a fast bactericidal and fungicidal action. It would also be useful, on the basis of further test, to suggest certain standard for an allowed number of conditionally pathogenic and saprophytic microorganisms which would be used by the instutions performing the blood transfusion and production of

In a pilot open-label study, we investigated the effect of a dietary supplement, BioCell Collagen® (BCC, which contains a naturally occurring matrix of hydrolyzed collagen type II and low-molecular-weight hyaluronic acid and chondroitin sulfate, in 26 healthy females who displayed visible signs of natural and photoaging in the face. Daily supplementation with 1 g of BCC for 12 weeks led to a significant reduction of skin dryness/scaling (76%, P = 0.002 and global lines/wrinkles (13.2%, P = 0.028 as measured by visual/tactile score. Additionally, a significant increase in the content of hemoglobin (17.7%, P = 0.018 and collagen (6.3%, P = 0.002 in the skin dermis was observed after 6 weeks of supplementation. At the end of the study, the increase in hemoglobin remained significant (15%, P = 0.008, while the increase in collagen content was maintained, but the difference from baseline was not significant (3.5%, P = 0.134. This study provides preliminary data suggesting that dietary supplementation with BCC elicits several physiological events which can be harnessed to counteract natural photoaging processes to reduce visible aging signs in the human face. A controlled study is necessary to verify these observations.Keywords: BioCell Collagen, chicken sternal cartilage extract, hydrolyzed collagen type II, low-molecular-weight hyaluronic acid, skin aging

  10. Aseptic loosening of the femoral implant after cemented total hip arthroplasty in dogs: 11 cases in 10 dogs (1991-1995)

    International Nuclear Information System (INIS)

    Objective-To determine clinical signs, radiographic findings, results of surgical management, and potential causes of aseptic loosening of the femoral implant (ALFI) in dogs that have undergone cemented total hip arthroplasty (THA). Design-Retrospective study. Animals-11 cases of ALFI in 10 dogs. Procedure-Medical records of all dogs undergoing THA revision surgery were reviewed. Only dogs with ALFI were included. The prosthesis and cement were removed by creating a longitudinal osteotomy of the cranial femoral cortex. Postoperative radiographs of all dogs that underwent THA during the study period were reviewed. Results-The most common clinical sign was intermittent, subtle. or non-weight-bearing lameness. On radiographs obtained after THA, contact of the distal stem tip with cortical endosteum was evident in all dogs. Radiographic changes at the time of diagnosis of ALFI included asymmetric periosteal reaction along the femoral diaphysis, radiolucent lines between the prosthesis and cement, altered implant position, and femoral fracture. Surgical revision yielded good or excellent results in 9 cases. In 1 dog. the implant became infected; in another, aseptic loosening recurred. Aseptic loosening was significantly more common in dogs in which there was contact between the distal stem tip and cortical endosteum than in dogs in which there was no contact. Clinical Implications-ALFI is an uncommon, but important, complication of THA, and radiography is warranted in dogs with clinical signs of ALFI. Initial centering of the prosthetic stem within the femoral shaft may reduce the incidence of ALFI

    To enhance implant stability and prolong the service life of artificial joint component, a new approach was proposed to improve the wear resistance of artificial joint component and endow artificial joint component with the biological efficacy of resistance to aseptic loosening. Strontium calcium polyphosphate (SCPP) were interfused in ultrahigh molecular weight polyethylene (UHMWPE) by a combination of liquid nitrogen ball-milling and flat-panel curing process to prepare the SCPP/UHMWPE composites. The micro-structure, mechanical characterization, tribological characterization and bioactivities of various SCPP/UHMWPE composites were investigated. The results suggested that this method could statistically improve the wear resistance of UHMWPE resulting from a good SCPP particle dispersion. Moreover, it is also observed that the SCPP/UHMWPE composites-wear particles could promote the production of OPG by osteoblasts and decrease the production of RANKL by osteoblasts, and then increase the OPG/RANKL ratio. This indicated that the SCPP/UHMWPE composites had potential efficacy to prevent and treat aseptic loosening. Above all, the SCPP/UHMWPE composites with a suitable SCPP content would be the promising materials for fabricating artificial joint component with ability to resist aseptic loosening.

    Humeral shaft aseptic nonunions occur in 2% to 10% of patients managed conservatively and 10% to 15% of patients treated surgically. The complex muscular and neurovascular anatomy of the upper limb makes the surgical approach to the fracture site demanding and risky, especially when previous surgeries have been attempted. The clinical consequence of atrophic humeral shaft nonunions is a severe functional limitation that may significantly affect activities of daily living, especially in the elderly. The surgical treatment of humeral shaft nonunions is challenging for orthopedic surgeons. Patients with atrophic nonunions require both a stable fixation and enhancement of the biologic response because of the weak biologic reaction observed at the fracture site. The gold standard of treatment in elderly patients has not been described. Nonetheless, older age and comorbidities are associated with potentially malignant nonunions. This study reports the authors' experience using opposite cortical allograft combined with bone morphogenetic protein 7 and mesenchymal stem cells to treat humeral shaft atrophic nonunions in 2 elderly patients. The nonunion site healed at 4 months (patient 1) and 8 months (patient 2) postoperatively, with full return to activities of daily living and no pain. Neither patient reported complications of the radial nerve, which is at high risk of injury during this type of surgery. The only reported complication (patient 2) was an intraoperative longitudinal partial distal humeral fracture, probably caused by compression screw overtightening. The use of a locking plate and opposite cortical allograft, combined with BMP-7 and mesenchymal stem cells, represents a safe and effective treatment for malignant nonunions in older patients.

    Activated mononuclear cells are an early event in the course of severe acute pancreatitis (SAP). To date, the molecular mechanism triggering peripheral blood mononuclear cells (PBMCs) is poorly understood. The aim of this paper was to determine the potential role of Card9 in SAP. We collected data from 72 subjects between January 2013 and June 2014. Subsequently, PBMCs were isolated on day 1, 3 and 5 of pancreatitis. Immunofluorescence staining, quantitative real-time PCR, Western blotting, immunoprecipitation and ELISA were used to determine the role of Card9 in SAP. Microbial culture showed that SAP patients at the early period did not develop any bacteria and fungi infection. Card9 expression in SAP patients was higher than that in mild acute pancreatitis and volunteer healthy controls, up to the peak on day 1. The monocyte-derived cytokines interleukin (IL)-17, IL-1β, IL-6 and tumour necrosis factor-α mediated by the induction of Card9 markedly increased in SAP patients compared with the control group. Furthermore, the inducible formation of Card9-Bcl10 complex was found in PBMCs, which may be involved in nuclear factor kappa B (NF-κB) and p38 activation in SAP. Receiver operating characteristic curve indicated that Card9 levels had a high sensitivity of 87.5% and specificity of 67.7%, showing the close correlation with SAP patients. Card9 overexpression was firstly found in aseptic SAP, which may be played an important role in NF-κB and p38 activation in PBMCs. It also provided the new insights into therapeutic interventions by targeting monocytes activation in SAP patients. PMID:26893103

    In a previous study, a quantitative microbial exposure assessment (QMEA) model applied to an aseptic-UHT food process was developed [Pujol, L., Albert, I., Magras, C., Johnson, N. B., Membré, J. M. Probabilistic exposure assessment model to estimate aseptic UHT product failure rate. 2015 International Journal of Food Microbiology. 192, 124-141]. It quantified Sterility Failure Rate (SFR) associated with Bacillus cereus and Geobacillus stearothermophilus per process module (nine modules in total from raw material reception to end-product storage). Previously, the probabilistic model inputs were set by experts (using knowledge and in-house data). However, only the variability dimension was taken into account. The model was then improved using expert elicitation knowledge in two ways. First, the model was refined by adding the uncertainty dimension to the probabilistic inputs, enabling to set a second order Monte Carlo analysis. The eight following inputs, and their impact on SFR, are presented in detail in this present study: D-value for each bacteria of interest (B. cereus and G. stearothermophilus) associated with the inactivation model for the UHT treatment step, i.e., two inputs; log reduction (decimal reduction) number associated with the inactivation model for the packaging sterilization step for each bacterium and each part of the packaging (product container and sealing component), i.e., four inputs; and bacterial spore air load of the aseptic tank and the filler cabinet rooms, i.e., two inputs. Second, the model was improved by leveraging expert knowledge to develop further the existing model. The proportion of bacteria in the product which settled on surface of pipes (between the UHT treatment and the aseptic tank on one hand, and between the aseptic tank and the filler cabinet on the other hand) leading to a possible biofilm formation for each bacterium, was better characterized. It was modeled as a function of the hygienic design level of the aseptic

    Full Text Available Idiopathic facial aseptic granuloma (IFAG is a rare, benign pediatric dermatological lesion that occurs in children between 8 months and 13 years of age. The pathogenesis of IFAG is still unclear but it is likely to be associated with granulomatous rosacea in childhood. Here we describe a case of IFAG in a 13-year-old boy who showed a dramatic response to oral doxycycline and topical metronidazole, which supports the hypothesis that IFAG may belong to the spectrum of rosacea.

    Objective To study the reconstruction method and effectiveness of titanium plate and Teflon patch for the chest wall after resection of sternal tumors. Methods Between October 2006 and November 2009, 4 patients with sternal tumors were treated and the thoracic cages were reconstructed. There were 2 males and 2 females, aged 30-55 years. The patients were admitted because of chest lump or pain. The sizes of palpable lump ranged from 4 cm×3 cm to 10 cm×8 cm. CT examination showed bone destruction. After sternal tumor resection, defect size ranged from 10 cm x 8 cm to 18 cm×4 cm, and titanium plate and Teflon patch were used to repair and reconstruct the chest wall defect. Results The operations of the tumor resection and reconstruction of chest wall defect were successfully performed in 4 cases. Incisions healed by first intention with no abnormal breath, subcutaneous emphysema, pneumothorax, and infection. One case failed to be followed up after 6 months; 1 case died of intracranial hemorrhage; and 2 cases were followed up 1 and 4 years respectively without tumor recurrence. The chest wall had good remodeling. No loosening and exposure of titanium plate, difficulty in breathing, chest distress, and chest pain were observed during follow-up. Conclusion Surgical resection of sternal tumors will cause large chest wall defect which can be repaired by titanium plate and Teflon patch because it had the advantages of easy operation, satisfactory remodeling, and less complication.%目的 探讨胸骨肿瘤切除术后采用钛板联合Teflon补片重建胸廓的方法及疗效.方法 2006年10月-2009年11月,收治4例胸骨肿瘤患者.男2例,女2例;年龄30~55岁.以胸部肿块、疼痛1~6个月后入院.检查见胸前区范围为4cm×3em~10cm×8cm的肿块,质硬.CT检查见骨质破坏.采用胸骨肿瘤扩大切除术,切除范围为10cm×8cm~18em×14cm,采用钛板联合Teflon补片重建胸廓.结果 患者手术均顺利完成.术后切口Ⅰ期

    Canine Steroid-Responsive Meningitis-Arteritis (SRMA) is a suitable animal model for studies on the development of neutrophilic pleocytosis in aseptic meningitis. Samples of dogs in the acute phase of SRMA (n=16) were examined for gene expression of matrix metalloproteinases (MMP)-2 and -9 and tissue inhibitors of metalloproteinases (TIMP)-1 and -2. Results were compared to those of dogs under glucocorticosteroid treatment for SRMA (n=16) and dogs with other inflammatory and neoplastic diseases of the central nervous system (CNS) (n=19). Samples included mononuclear (PBMCs) and polymorphonuclear cells (PBPMNs) of peripheral blood and cerebrospinal fluid white blood cells (CSF WBCs). In the acute phase of SRMA CSF WBCs showed mRNA expression for MMP-2 and -9 and TIMP-1 and -2, highlighting a contribution of these cells to the overall content of MMPs and TIMPs in CSF. MMP-2 mRNA levels in CSF WBCs were significantly up-regulated in comparison to PBMC expression levels, suggesting that MMP-2 is relevant for PBMC invasion into the subarachnoidal space and that the expression is influenced by migratory activity through the blood-CSF-barrier.

  12. The value of contrast and subtraction arthrography in the assessment of aseptic loosening of total hip prostheses: A meta-analysis

    International Nuclear Information System (INIS)

    Objective: To summarize and compare the diagnostic accuracy of contrast and subtraction arthrography in the assessment of aseptic loosening of total hip arthroplasties. Design: This meta-analysis was performed using methods described by the Cochrane Methods Group on Systematic Reviews of Screening and Diagnostic Tests. We included original, English-language papers published between January 1975 to October 2004 that examined contrast-enhanced arthrography with or without subtraction for diagnosis of loosening of total hip prostheses. A qualitative and quantitative analysis was performed by two investigators. Results: With regard to the acetabular component, pooled sensitivity and specificity for contrast arthrography was 70% (95% confidence interval, 52-84) and 74% (95% CI, 53-87), respectively. Subtraction arthrography had a significantly higher sensitivity of 89% (95% CI, 84-93) (p = 0.01), with a similar specificity of 76% (95% CI, 68-82). For the femoral component, pooled sensitivity and specificity for contrast arthrography were 63% (95% CI, 53-72) and 78% (95% CI, 68-86). Pooled estimates for subtraction arthrography revealed a significantly higher sensitivity of 86% (95% CI, 74-93) (p = 0.003). Specificity was 85% (95% CI, 77-91) and was similar to the data of contrast arthrography (p = 0.23). Conclusion: Using the present data we found that the subtraction arthrography is a sensitive technique for detection of loosening of total hip prostheses, offering added value over contrast arthrography, especially for evaluation of the femoral component

    Descriptive analysis and consumer acceptance tests were conducted with frozen (FCR), homemade (HCR), and aseptic-packaged (ACR) cooked rice products from two cultivars-IM and SD. FCR was prepared using a rapid freezing process, which may provide consumers with a quality similar to that of HCR. The intensity of the flavors of roasted, glutinous rice, rice cake, and rice starch and the textures of glutinousness, moistness, chunkiness, adhesiveness, and squishiness were all greater in the FCR as compared to the HCR and ACR (p0.05); however, in most cases these factors showed significant differences when compared with ACR (p<0.05). From partial least square regression analysis, cooked rice was positively related to sweet, transparency, glossiness, roasted, glutinousness, chunkiness, moistness, glutinous rice, adhesiveness, rice shape, rice starch, and squishiness attributes but negatively related to raw rice, old rice, old rice aroma, a particle feeling, off-aroma, white color, scatteredness, slickness, size of cooked rice, and firmness attributes.

    An aseptic meningitis outbreak occurred in Luoding City of Guangdong, China, in 2012, and echovirus type 30 (ECHO30) was identified as the major causative pathogen. Environmental surveillance indicated that ECHO30 was detected in the sewage of a neighboring city, Guangzhou, from 2010 to 2012 and also in Luoding City sewage samples (6/43, 14%) collected after the outbreak. In order to track the potential origin of the outbreak viral strains, we sequenced the VP1 genes of 29 viral strains from clinical patients and environmental samples. Sequence alignments and phylogenetic analyses based on VP1 gene sequences revealed that virus strains isolated from the sewage of Guangzhou and Luoding cities matched well the clinical strains from the outbreak, with high nucleotide sequence similarity (98.5% to 100%) and similar cluster distribution. Five ECHO30 clinical strains were clustered with the Guangdong environmental strains but diverged from strains from other regions, suggesting that this subcluster of viruses most likely originated from the circulating virus in Guangdong rather than having been more recently imported from other regions. These findings underscore the importance of long-term, continuous environmental surveillance and genetic analysis to monitor circulating enteroviruses.

    We determined four complete nucleotide sequences of echovirus 6 (E6) isolated from an epidemic of aseptic meningitis (AM) in Hokkaido, Japan, in 2011. Phylogenetic analysis of the genes encoding viral capsid protein 1 revealed that the strains were closely related to E6 strains isolated in China in recent years, but they were distantly related to E6 strains isolated from patients with AM in Osaka Prefecture, Japan, in 2011. The genes encoding the viral protease and RNA-dependent RNA polymerase (3CD) were closely related to those of several non-E6 strains of the species Human enterovirus B isolated in China, South Korea, and Australia from 1999 to 2010, resulting in a novel cluster in the phylogenetic tree. These results suggest that the incidence of AM in Japan in 2011 was caused by at least two lineages of E6 strains, and a lineage of the 3CD gene was interspersed among different serotypic strains isolated in Western Pacific countries.

    Aseptic meningitis and bacterial meningitis after neurosurgical operation are the postoperative complications which are difficult to identify clinically. They have great differences in treatment and prognosis. The pathogenesis of the postoperative aseptic meningitis is not clear. Its clinical manifestations are similar to bacterial meningitis, but the prognosis is better. The traditional diagnostic methods for postoperative aseptic meningitis has a certain degree of the rate of missed diagnosis and misdiagnosis. In recent years, scholars of the world have conducted many studies on the diagnosis and treatment of postoperative aseptic meningitis, and made some progress, which has improved the diagnostic accuracy of postoperative aseptic meningitis to a certain degree, guided the treatment correctly and reduced patients unnecessary expenses and hospital stays.%神经外科术后无菌性脑膜炎与细菌脑膜炎一直是临床上较难鉴别的术后并发症,二者在治疗过程和预后方面有较大差异。术后无菌性脑膜炎的发病机制尚不明确,临床表现与细菌性脑膜炎相似,易被误诊为细菌性脑膜炎,但预后较好。传统的检查诊断方法对于术后无菌性脑膜炎存在一定程度的漏诊率和误诊率,近年来国内外学者对术后无菌性脑膜炎的诊断及治疗方法进行了多方面的研究,并取得了一些成果,在一定程度上提高了此类术后并发症诊断的准确率,正确指导此类术后并发症的治疗,减少患者不必要的花费及患者的住院时间。

    Aseptic loosening ( AL ) is one of the most common complications in tumor prostheses. Loss of bone quantity and decline of bone quality are the main challenges that orthopedists encounter when they deal with AL. Based on the latest reports, prosthesis revision is the primary choice in the treatment of AL, and it can provide relatively satisfactory outcomes when compared with other methods. While it needs enough bone quantity and good bone quality for prosthetic stability. In some reports, it can get a median Musculoskeletal Tumor Society ( MSTS ) functional score of 96% ( range: 50%-100% ) after an average follow-up of 101 months ( range: 47-155 months ) after the surgery. Besides this, allograft-prosthesis composites ( APCs ) are another choice. Allograft segments are used to construct a certain ifxation arm to get a more stable ifxation. However, its outcomes are not as satisfactory as that of prosthesis revision. According to some reports, after an average follow-up of 59 months after the surgery, it can provide an average MSTS functional score of 62% ( range: 57%-67% ). While we must take account that these patients receiving APCs always have less bone quantity and worse bone quality, when compared with those only receiving prosthetic treatment. In recent years, a new type of prosthesis based on extra-cortical plate ifxation has been used in the revision, which is superior to the conventional intramedullary stem prosthesis. The current results illustrate that it has certain application prospects, but high-quality studies are needed to further demonstrate it. When the loss of bone quantity and decline of bone quality are too serious to perform limb salvage treatment, rotationplasty and amputation may be a choice. However, great attention must be paid to their indications.

    Since there are limited data on the incidence and clinical findings of central nervous system (CNS) infection by three α-herpesviruses including human herpes simplex virus 1 (HSV-1), HSV-2 and varicella-zoster virus (VZV) in Korea, a retrospective analysis of clinical data and polymerase chain reaction (PCR) results was performed in patients who presented with suspicion of acute viral meningitis and/or encephalitis at the emergency department of a tertiary referral hospital in Seoul, Korea. During the 3-year study period, a total of 224 cerebrospinal fluid (CSF) samples from 224 patients were examined. Among the 224 patients, 135 (60.3%) patients were identified as having aseptic meningitis (n = 70, 51.9%), encephalitis (n = 41, 30.4%) or meningoencephalitis (n = 24, 17.8%) at discharge. Twenty-four (17.8%) patients were identified as having VZV meningitis (n = 16, 11.9%), VZV meningoencephalitis (n = 2, 1.5%), HSV-2 meningitis (n = 4, 3.0%), or HSV-1 encephalitis (n = 2, 1.5%). Of the 24 patients infected with the three herpesviruses, immunocompromised patients accounted for 33.3% (n = 8). Skin rashes were observed in half (n = 9) of the patients with VZV, and none with HSV-1 or HSV-2. One patient with VZV meningitis and four patients with brain parenchymal involvement had neurologic sequelae. In conclusion, three herpesviruses are important causative agents of CNS infectious disease with significant morbidity in adults, regardless of the immunologic status. Therefore, CSF should be examined for HSV-1, HSV-2, and VZV using sensitive diagnostic methods in all cases of adult patients with clinical manifestations of CNS disease in order to identify the correct etiology and to determine appropriate therapy.

Goeringii, C. Serratumr and C. Ebumeum were studied. The results showed that, the seed pre-treatment, the basic media, the hormone combination and the fruit supplements of media had effects on seed germination. The hormone and coconut milk supplemented had significant effects on seed germination; Seeds pre-treatment with NaClO or NaOH and low salt medium made the seed germinate earlier and unproved the germination rate. The preferred pre-treatment method was that the seeds were soaked in the solution of 0.1 mol/L NaOH or 1 % NaClO for 20 min before sowing in the medium. The optimum media for seeding was modified Kyoto supplemented with 2 mg/L 6-BA, 1 mg/L NAA and 10 % coconut milk.

    Aim: Identification of typical patterns for fluorodeoxyglucose (FDG) uptake in positron emission tomography (PET) to detect aseptic loosening of hip prosthesis (acetabular and/or femoral component) and prosthetic infection. Methods: 18 patients with painful hip prosthesis underwent PET using a dedicated full ring scanner after application of 200-300 MBq FDG. The interface between bone and surrounding soft tissue or bone as displayed on coronal slices was divided into 12 segments in accordance with the classifications of Delee and Gruen. FDG uptake in each of the segments was scored (0-3) by two independent observers. Intraoperative findings were regarded as the gold standard. Results: After surgical revision 14 acetabular components and 9 femoral components were found to be loose and prosthetic infection was present in 7 prostheses. Loosening of the acetabular component was correlated to enhanced uptake in the middle of the acetabular interface, while loosening of the femoral component was correlated to enhanced uptake in the proximal and middle segment of the lateral femoral interface and the proximal segment of the medial femoral interface. A similar pattern was found in prosthetic infection with high uptake along the middle portion of the lateral femoral interface. In 6 of 7 infected prostheses loosening of the acetabular and of the femoral component was present. Taking the typical uptake patterns as criteria for loosening and grade 3 uptake as an additional criterion for septic loosening the accuracy of PET imaging in the detection of loosening of the acetabular or the femoral component and of prosthetic infection was 72, 78 and 89%, respectively. Conclusion: This pilot study presents FDG-PET as a promising diagnostic tool for patients with painful hip prostheses. Its clinical value should be evaluated in a larger patient population. (orig.)

    Full Text Available The neonatal mortality rate in India is high and stagnant. Special Care Newborn Units (SCNUs have been set up at different levels of Health Care Delivery System to provide quality newborn-care services in several hospitals to meet this challenge. Many units are located in the districts where the burden of neonatal deaths is high, and access to special newborn care is poor. The study was conducted to assess the functioning of SCNUs in six centers of India. The evaluation was based on an analysis of secondary data from the six units that had been functioning for at least three year. A cross-sectional survey was also conducted to assess the availability of Quality care and Aseptic practices implemented at different levels of SNCUs. Descriptive statistics were used for analyzing the inputs (Quality care and aseptic practices and outcomes (morbidity and mortality. The rate of mortality among admitted neonates was taken as the key outcome variable to assess the performance of the units. Chi-square test was used for analyzing the trend of case-fatality rate over a period of 3 years considering the first year of operationalization as the base. Correlation coefficients were estimated to understand the possible association of case-fatality rate with factors, such as bed:doctor ratio, bed:nurse ratio, average duration of stay, and bed occupancy rate, and the asepsis score was determined. The rates of admission increased from a median of 16.7 per 100 deliveries in 2012 to 19.5 per 100 deliveries in 2014. The case-fatality rate shows progressive decline in all the units in Last 3 years. Proportional mortality due to sepsis and low birthweight (LBW declined significantly over two years (LBW <2.5 kg. The major reasons for admission and the major causes of deaths were birth asphyxia, sepsis, and LBW/prematurity. The units had a varying nurse:bed ratio (1:1-1:2.14. The bed occupancy rate ranged from 83% to 121% (median 115%, and the average duration of stay

    Objective To study the effect of different materials of cork, puncture methods and frequencies on the aseptic storage period of normal saline injection kept in PIVAS. Methods We grouped normal saline injection bottles according to the materials of the cork (butyl or polyisoprene ), puncture methods(stochastic puncture or repeated puncture of a single site of the cork) and puncture frequencies(three or five times). Sterility test were taken immediately after the puncture, and at 1 h, 2 h,3 h,4 h,5 h,6 h,8 h, 10h and 12 h within storage. Results The normal saline injection with polyisoprene cork stayed aseptic within 10 h after the corks were punctured 3 or 5 times randomly. The injection stayed sterile within 6 h after 3 times of, or within 5 h after 5 times of puncture through a single site of the cork. The normal saline injection with butyl cork stayed aseptic within 8 h after 3 times of, or within 6 h after 5 times of stochastic puncture. The injection with butyl cork stayed sterile within 5 h after 3 times of, or within 4 h after 5 times of puncture through a single site of the cork. Conclusion Normal saline injection with two different materials of the cork is able to stay sterile within 4 h regardless of the puncture methods or frequencies. The storage period of normal saline injection whose corks are repeatedly punctured at a single site is shortened with increasing puncture frequency. Normal saline injection with butyl cork shows shorter storage period compared with those with polyisoprene cork. The results indicate that we should strictly obeythe misalign rules during intravenous drug preparation. Meanwhile, the procedure calls for advisable arrangement of drug preparation time according to the drug properties and usage requirements.%目的 研究静脉药物配置中心环境下瓶塞材质、穿刺方法及穿刺次数对生理盐水无菌存放时间的影响.方法 将静脉输液用生理盐水按胶塞的材质(丁基胶塞和聚异戊二烯胶塞)

    Purpose: Numerous clinical observations demonstrate the efficacy of low radiation doses in the treatment of painful osteoarthritis. Experimental investigations remain scarce. We investigated the effects of locally daily 5 times 1.0 Gy 60-Co irradiation on an artificially induced aseptic gonarthritis in rabbits. Material and methods: Three separate experiments (EV) were performed (10 rabbits per experiment, 5 treated/5 controls; duration: EV1: 18 days; EV2: 6 days; EV3: 29 days). An aseptic arthritis in the right knee joint of rabbits was induced by intraarticular injection of 0.5 ml papain solution (3%, 30,000 USP/mg) on day 0. The arthritic knee joint of the anesthesized animals was irradiated daily from day 1 to 5 with 5 times 1.0 Gy. The controls were sham-irradiated under the same conditions. The time course of arthritis in treated animals and sham-treated controls was evaluated by clinical, laboratory-chemical and histological criteria. The clinical investigation was performed daily, the puncture of the knee-joints was carried out several times in EV1, and at the end of experiments in EV2 and EV3. At the end of the observation period, animals were killed and the knee joints excised for histological analysis. Results: The intraarticular injection of papain caused a peracute inflammatory response in all animals. After 1 week the chronical stage was reached, and the experimental arthritis resolved slowly within several weeks. Local irradiation accelerated the decrease of inflammatory joint swelling, being significant by day 4. On day 6 the volume of synovial fluid in irradiated knee-joints was significantly smaller. The morphometric data indicated a reduction in thickness of synovial membrane, a decrease in number of synovial cell layers, and a decrease in distance between capillaries and the synovial membrane surface following irradiation of arthritic joints.

    目的:探讨鸡软骨酶解产物的理化性质及对类风湿性关节炎(RA)大鼠的免疫调节作用。方法:采用胃蛋白酶水解鸡胸软骨,研究软骨酶解产物的组成及理化性质,并建立大鼠类风湿性关节炎模型,探讨软骨酶解产物对大鼠类风湿性关节炎的免疫调节作用。结果:鸡胸软骨酶解产物的主要成分为Ⅱ型胶原,变性温度为43.843℃,在pH值大于5.8,NaCl浓度大于0.9mol/L时,溶解度较低。口服鸡胸软骨酶解产物显著抑制了RA大鼠的足掌肿胀,并降低了其血清抗Ⅱ型胶原(CII)抗体及滑膜炎性细胞因子的水平。结论:鸡胸软骨酶解产物可能通过调节Th1细胞因子的表达、纠正失衡的Th1/Th2细胞因子网络及降低血清特异性抗CII抗体的水平对RA产生防治作用。%Purpose: To investigate physicochemical properties of the pepsin hydrolysate of chicken sternal cartilage and its immunoregulatory function in rats with rheumatoid arthritis (RA). Methods: RA was induced in rats by collagen type II injections. Results: The pepsin hydrolysate consisted mainly of collagen type II with a denaturation temperature of 43.843℃. However, the solubility was low at pH above 5.8 and NaC1 concentrations above 0.9 mol/L. Oral administration of the hydrolysate decreased significantly the swelling of paws, the serum level of anti-collagen type II antibody and secretion of proinflammatory cytokines in RA rats. Condusion: The pepsin bydrolysate can prevent and treat RA probably by regulating the expression of Thl and Th2 cytokines, correcting the imbalance of Thl/Th2 cytokines network, and decreasing the serum concentration of anti-collagen type II antibody.

    A design of aseptic packaging system integrated as the end part of the staple wheat food product line is studied, in order to keep the quality of the staple wheat food in the period of the distribution and sale.There are 3 basic parts in the aseptic packaging system, i.e. drying unit, compound sterilization units and packaging unit, considering influence factors for the food quality during storage and circulation as well as fresh-keeping packaging technology. Three basic parts can be freely used for different kinds of staple wheat food. Four technical schemes of aseptic packaging line are established according to different kinds of drying, sterilization and packaging techniques. The 4 schemes are studied with the analytic hierarchy process (AHP) method. In the AHP analysis process, the hierarchy with 3 criteria i.e. working performance, economic efficiency and reliability, and 9 sub-criteria is established. Through evaluation and priority considering, the optimum scheme is chosen. The aseptic packaging line is carefully designed, which is composed of the infrared drying unit, compound sterilization units of ultraviolet (UV), low temperature, Ozone, packaging machine, and reasonable product flow. In order to achieve industrial production of aseptic packaging for different kinds of staple wheat food, the line can be program-controlled with adjustable parameters, such as drying time, drying temperature, sterilization time, UV illumination intensity and Ozone intensity. The aseptic packaging system is set up in accordance with the above optimum scheme by the AHP method. Chinese steamed bread made of flour with primary moisture content of 43% have been processed by the compound sterilization units of aseptic packaging system under the condition of 4℃,relative humidity (RH) of 50%-70%, UV illumination intensity of 90-100µW/m2 and Ozone intensity of 40-60 mg/m3. For processed and the naturally placed Chinese steamed bread, the comparative tests of color, texture and

    Full Text Available Foram estudadas informações obtidas do prontuário de 573 crianças com idade entre 1 mês e 15 anos e diagnóstico de meningite, internadas no Hospital Couto Maia, na cidade de Salvador-Bahia, no período de janeiro-1990 a dezembro-1992. Crises epilépticas, diminuição do nível de consciência e rigidez de nuca foram mais frequentes no grupo com meningite bacteriana. Glicorraquia menor que 45 mg/dL, proteinorraquia igual ou superior a 140 mg/dL e celularidade liquórica superior a 600 cels/mm³ mostraram-se preditores de meningite piogênica. A análise da curva ROC foi utilizada para estabelecer o melhor ponto de corte nas medidas liquóricas de celularidade, proteínas e glicose capaz de predizer meningite bacteriana. Os resultados encontrados enfatizam que informações clínicas, obtidas com a anamnese e o exame neurológico, e liquóricas simples, definidas pelos níveis de proteína, glicose e análise da celularidade, podem ser utilizadas como medidas de grande acurácia para diferenciar meningite piogênica de asséptica em crianças.We reviewed the charts of 573 children with a final diagnosis of pyogenic or aseptic meningitis, who were hospitalized in a large reference hospital for the treatment of infectious disease, from January 1990 to December 1992. Seizures, decreased consciousness, nuchal rigidity were more frequent in bacterial than in aseptic meningitis. A cerebrospinal fluid (CSF glucose level lower than 45 mg/dL, a protein level equal or greater than 140 mg/dL and cell count greater than 600/mm³ were predictors of pyogenic meningitis. Receiver operating characteristic curve analysis was used to assess the best point in CSF measures of leukocytes, glucose and protein that could predict bacterial meningitis. These results suggest that clinicians should differentiate bacterial from aseptic meningitis in children with greater accuracy utilizing only clinical and simple CSF data.

    Percutaneous osteoplasty (POP) as a technical extension of percutaneous vertebroplasty has been used as a treatment for osteolytic lesions in weight-bearing bones besides the vertebrae, and has demonstrated beneficial outcomes in terms of pain relief and functional improvement. However, its efficacy in non-weight-bearing bones is not well known. Herein, we present the case of a patient with an osteolytic lesion from multiple myeloma in the sternum, a non-weight-bearing bone, who obtained sustained pain relief and improvement of life quality after POP. These data suggest that POP may be an alternative treatment for osteolytic lesions in non-weight-bearing bones. (orig.)

    Purpose. The purpose of our study is to evaluate the therapeutic efficacy of short-segment percutaneous pedicle screw fixation with polymethylmethacrylate (PMMA) augmentation for the treatment of osteoporotic thoracolumbar compression fracture with osteonecrosis. Methods. Osteoporotic thoracolumbar compression fractures with avascular necrosis were treated by short-segment PPF with PMMA augmentation. Eighteen were followed up for more than 2 years. The kyphotic angle, compression ratio, visual analog scale (VAS) score for back pain, and the Oswestry Disability Index (ODI) were analyzed. In addition, radiologic and clinical parameters of PPF group were compared with percutaneous vertebroplasty (PVP) group. Results. Vertebral height and kyphotic angle of the compressed vertebral bodies were significantly corrected after the operation (P lower in the PPF group (P < 0.05). The postoperative ODI and VAS of the PVP group were significantly higher than the PPF (P < 0.05). Conclusions. According to our results, short-segment PPF with PMMA augmentation may be an effective minimally invasive treatment for osteoporosis in cases of osteoporotic vertebral compression fractures with Kummell's osteonecrosis.

    2013-03-01

    Full Text Available Background: Crowned dens syndrome (CDS, related to microcrystalline deposition in the periodontoid process, is the main cause of acute or chronic cervical pain. Microcrystal-line deposition most often consists of calcium pyrophosphate dehydrate crystals and/or hydroxyapatite crystals. Case Presentation: This report describes the case of an 89-year-old woman who presented with sudden onset, high fever, severe occipital headache, and neck stiffness. A laboratory examination revealed a markedly elevated white blood cell count (11,100/µl and C-reactive protein level (23.8 mg/dl. These clinical findings suggested severe infection such as meningitis with sepsis. However, the results of blood culture, serum endotoxin, and procalcitonin were all negative, and cerebrospinal fluid studies revealed only a slight abnormality. The patient was first diagnosed with meningitis and treated with antiviral and antibiotic agents as well as non-steroidal anti-inflammatory drugs, but they only had limited effects. A cervical plain computed tomography (CT scan and its three-dimensional (3D reconstruction detected a remarkable crown-like calcification surrounding the odontoid process. On the basis of the CT findings, the patient was diagnosed as a severe case of CDS and was immediately treated with corticosteroids. The patient's condition drastically improved within a week after one course of corticosteroid therapy. Conclusion: Some atypical symptoms of CDS are misleading and may be misdiagnosed as meningitis, as happened in our case. A CT scan, especially a 3D-CT scan, is necessary and useful for a definitive diagnosis of CDS. CDS should be considered as a differential diagnosis of a possible etiology for fever, headache, and cervical pain of unknown origin.

  7. Low energy electrons for pasteurization and aseptic practice

    International Nuclear Information System (INIS)

    The enhanced stopping power of matter for electrons in the energy range under 300 kiloelectronvolts renders them particularly effective for the 'non-chemical' pasteurization of raw produce, as well as for the high speed sterilization of container material. Performance data for electron sterilizers operating in the 130 to 250 kilovolt regime will be presented along with a discussion of the thin film dosimetry techniques used for their characterization. This process is particularly attractive for citrus processing as the energy need only be delivered to the upper epidermis with a depth of penetration of 100 μ. The inner mesocarp or albedo, and the endocarp or edible pulp of the fruit, are unaffected by the process. The lethality of 100 keV electrons for some typical fruit pathogens has been studied in this laboratory. These include typical penicillin molds (P. chrysogenum) and the common brown stem rot (Phyt. citrophthora). D values for these, both on the outer surface of the orange flavedo and on specimens of controlled geometry, are reported. These results indicate that 100 keV electron treatment at surface levels of 0.2 megarads is adequate for in vitro control of these pathogens. (author)

    1992-11-15

    A Standardbred filly was admitted for evaluation of pleuritis and pneumonia. Heart rate was 80 to 120 beats/min, and the pulse was barely palpable. Thoracic and abdominal ultrasonography and echocardiography revealed substantial pericardial effusion with cardiac tamponade, fibrinous pericarditis, pleural effusion, and ascites. Initial electrocardiography revealed normal sinus rhythm with decreased amplitude of the QRS complexes consistent with pericardial effusion. Following thoracentesis, echocardiogram-guided pericardiocentesis was performed. Bacterial culture yielded no growth from any of the fluids, and bacteria were not seen on cytologic examination. Initial treatment included broad-spectrum antibiotic treatments, IV fluid therapy, and anti-inflammatory agent administration. On the basis of negative culture results, an immune-mediated cause was considered, and dexamethasone was instituted in a decreasing dosage regimen. Pericardial effusion, ventral edema, and ascites began to resolve within 3 days after beginning dexamethasone treatment. Thirty days following discharge, the filly was reexamined, and at that time, the prognosis for athletic performance was considered good so the horse was returned to race training. The final diagnosis in this case was idiopathic, effusive, nonconstrictive pericarditis with tamponade. Early identification, clinical understanding, and application of knowledge of the pathophysiologic mechanisms of pericarditis in horses, combined with use of diagnostic aids such as ultrasonography and aggressive therapy consisting of effusion drainage, pericardial lavage, antibiotics that penetrate the pericardium, and corticosteroids when indicated are critical for a successful outcome in horses with pericarditis.

    Immune-mediated central nervous system inflammation is described in a series of 12 juvenile boxer dogs. A diagnosis of steroid-responsive meningitis-arteritis was made based on the clinical presentation and on diagnostic findings. The boxer breed was at a higher risk for this inflammatory condition than other breeds. Long-term follow-up (>2 years) confirmed a better prognosis in this breed than in the beagle and the Bernese mountain dog. Complete resolution of clinical signs without significant deficits or recurrences was obtained in all cases. Early clinical recognition and immunosuppressive treatment resulted in a better response and complete resolution of the disorder. PMID:16822766

The patients were divided into three Herring groups according to radiographic images (A, B and C. For all patients the acetabulum/head index (AHI was determined. Results The youngest patient was 4.9 years and the oldest 9.11 years; male patients were dominant (male:female 11:3. The right hip side was more affected comparing to the left one (8:6. The distribution of patients in Herring groups was three in the Group A, six in the Group B and five patients in the Group C. The AHI index was lowest in the group C. Patients in the group C were treated surgically. Conclusion Herrings classification predicts patients with extensive changes and suggests what kind of treatment should be applied.

    Treatment of Avascular Osteonecrosis (AVN) of the femoral head to prevent progression to an arthritic hip is a challenging subject. Many conservative treatment options have been proposed in the literature. Weight bearing restriction as a stand-alone therapy is insufficient in preventing disease progression but it may be useful when combined with pharmacological agents or surgery. Bisphosphonate treatment in AVN might be efficient in early stages of disease, however there are no clear recommendations on length of treatment and therapeutic dosage and, considered the limited evidence and potential side effects of treatment, it could be considered in a pre-collapse stage in selected cases. Current literature suggests that low molecular weight heparin could lower disease progression in idiopathic AVN with quality of evidence being very low. Also the evidence to support the use of statins or vasodilators in the treatment of osteonecrosis is very low and their use cannot be recommended. Extracorporeal shock wave therapy may improve pain and function in early stages of disease with a low evidence, but there doesn't seem to be a significant change in time to the occurrence of femoral head collapse. Only one study has been conducted with pulsed electromagnetic fields therefore no recommendation can be given on clinical use of PEF in AVN. Evidence on hyperbaric oxygen therapy in the treatment of AVN is very limited and the high cost of treatment and the limited availability of structures that can provide the service poses other concerns about its feasibility. Based on current evidence, conservative treatment may be considered in early stages of asymptomatic AVN instead of observation only. PMID:27134631

    In Europe post-consumer beverage carton packages are treated in three ways: dumped in a landfill, incinerated for energy recovery, and recycled. In recent years new technologies for beverage carton recycling have been developed and tested. At the same time in Europe the collection of second-hand raw materials is becoming more efficient. In order to facilitate and justify the decision-making process, different possibilities of poly-aluminium handling were analysed. For this reason, the objective of this study was to compare carbon footprints in the whole life cycle of selected technologies and to provide decision-making with data for beverage carton recycling. The paper is based on some of the results of the project 'Sustainable Production through Innovations in small- and medium-sized enterprises (SPIN)'.

    Full Text Available Investigation of the aetiology of viral meningitis in Brazil is most often restricted to cases that occur in the Southern and Southeastern Regions; therefore, the purpose of this study is to describe the viral meningitis cases that occurred in state of Pará, Northern Brazil, from January 2005-December 2006. The detection of enterovirus (EV in cerebrospinal fluid was performed using cell culture techniques, RT-PCR, nested PCR and nucleotide sequencing. The ages of the 91 patients ranged from 60 years old (median age 15.90 years. Fever (87.1%, headache (77.0%, vomiting (61.5% and stiffness (61.5% were the most frequent symptoms. Of 91 samples analyzed, 18 (19.8% were positive for EV. Twelve were detected only by RT- PCR followed by nested PCR, whereas six were found by both cell culture and RT-PCR. From the last group, five were sequenced and classified as echovirus 30 (Echo 30. Phylogenetic analyses revealed that Echo 30 detected in Northern Brazil clustered within a unique group with a bootstrap value of 100% and could constitute a new subgroup (4c according to the phylogenetic tree described by Oberste et al. (1999. This study described the first molecular characterization of Echo 30 in Brazil and this will certainly contribute to future molecular analyses involving strains detected in other regions of Brazil.

    Globally breast cancer is the leading cause of cancer death among women. The breast consists of epithelium, stroma and a mucosal immune system that make up a complex microenvironment. Growing awareness of the role of microbes in the microenvironment recently has led to a series of findings important for human health. The microbiome has been implicated in cancer development and progression at a variety of body sites including stomach, colon, liver, lung, and skin. In this study, we assessed breast tissue microbial signatures in intraoperatively obtained samples using 16S rDNA hypervariable tag sequencing. Our results indicate a distinct breast tissue microbiome that is different from the microbiota of breast skin tissue, breast skin swabs, and buccal swabs. Furthermore, we identify distinct microbial communities in breast tissues from women with cancer as compared to women with benign breast disease. Malignancy correlated with enrichment in taxa of lower abundance including the genera Fusobacterium, Atopobium, Gluconacetobacter, Hydrogenophaga and Lactobacillus. This work confirms the existence of a distinct breast microbiome and differences between the breast tissue microbiome in benign and malignant disease. These data provide a foundation for future investigation on the role of the breast microbiome in breast carcinogenesis and breast cancer prevention. PMID:27485780

    Science.gov (United States)

    Ljungqvist, Bengt; Reinmüller, Berit

    2007-01-01

    In pharmaceutical manufacturing, freeze-drying processes can be adversely affected by temperature differences relative to the surrounding air. Loading and unloading of freeze-dryers are performed either without or with temperature differences between the cleanroom and the chamber of the freeze-dryer. This operation can cause a flow of room air through the opening, creating a contamination risk, especially when manual handling of material is performed in this area. To minimize this risk, a high-efficiency particulate air (HEPA) filter unit should be installed above the opening to provide clean air and protect the opening. Here the theoretical relationships are discussed and design criteria are presented.

    2012-01-01

    Penetrating hand wounds are common and these are managed by thorough debridement. However, stab wounds without evidence of divided structures are often treated with irrigation using antiseptic substances, antibiotic therapy, and immobilization. Octenisept® (Schülke & Mayr Ltd) is a widely used antiseptic agent for disinfection of acute or chronic wounds. It has a broad spectrum of antiseptic efficacy and has become an antiseptic of first choice in many hospitals. Within a few months, four patients presented to us with chronic inflammation and severe tissue necrosis after irrigation of penetrating hand wounds with Octenisept®. Repeated surgery and debridement was required in all patients. Wound healing was prolonged and patients had persisting oedema. Penetrating hand wounds must not be irrigated with Octenisept®.

    This study was designed to compare the efficacy of four hand preparation techniques in removing bacteria from the hands preoperatively. The effect of bacteriological swabbing itself on bacterial counts was also investigated. The numbers of bacteria obtained from the dominant and non-dominant hands were also determined. The techniques all used 4 per cent chlorhexidine gluconate, and consisted of rubbing for five minutes with one application of antiseptic; rubbing for five minutes with five applications of antiseptic; rubbing for one minute with one application of antiseptic; and scrubbing with a brush for five minutes with one application of antiseptic. The results showed that the four techniques were equally effective at removing bacteria. There was no significant difference in the bacterial counts obtained from the dominant and non-dominant hands. The wearing of gloves for up to 30 minutes after scrubbing had no effect on the bacterial counts. Swabbing itself significantly reduced the number of bacteria cultured from the hands.

    Before the re-introduction of the current generation of total hip resurfacing arthroplasty, component loosening and osteolysis were of great concern to the orthopaedic community. Early, mid- and long-term clinical results are encouraging, but component loosening still exists. Macroscopic, contact radiographic and histopathological analyses after undecalcified preparation of bone tissue specimens were performed. To investigate the frequency and morphological patterns of the loosening of the femoral component, we analysed a series of 190 retrieved femoral remnants that were revised for aseptic failures. Thirty-five (18.4%) hips were revised for clinical and/or radiographic loosening of the femoral component. Pseudoarthrosis (n = 17; median in situ time: 16 weeks, interquartile range [IQR]: 9 to 34), collapsed osteonecrosis (n = 5; median in situ time: 79 weeks, IQR: 63 to 97), cement-socket debonding (n = 3; median in situ time: 89 weeks, IQR: 54 to 97) and at later follow-up bone-cement loosening (n = 10; median in situ time: 175 weeks; IQR 112 to 198; p =0.005) were distinct patterns of the femoral remnant-implant loosening. Fibrocartilaginous metaplasia of interface bone trabeculae (n = 38; median in situ time: 61 weeks, IQR: 32 to 138) was strongly associated with femoral component loosening (p = 0.009). Both the trabecular hyperosteoidosis (n = 32; median in situ time: 71 weeks, IQR 50 to 129) and excessive intraosseous lymphocyte infiltration (n = 12; median in situ time: 75 weeks, IQR 51 to 98) at the bone-cement interface correlated strongly with fibrocartilaginous metaplasia (p = 0.001 and p = 0.016 respectively) and all three lesions were associated with the female gender (p = 0.021, p = 0.009, and p = 0.051). Femoral component loosening at early follow-up was mostly caused by pathological changes of the femoral remnant bone tissue: pseudoarthrosis and collapsed osteonecrosis. Fibrocartilaginous metaplasia was frequently observed in hips with femoral

  12. Macrophage imaging by USPIO-enhanced MR for the differentiation of infectious osteomyelitis and aseptic vertebral inflammation

    International Nuclear Information System (INIS)

    The purpose of this study was to prospectively evaluate USPIO-enhanced MR imaging for the differentiation of vertebral infectious osteomyelitis and sterile inflammation. Vertebral osteomyelitis and sterile vertebral inflammation were induced in two groups of six rabbits each. MRI examinations were performed including unenhanced and gadolinium-enhanced fat-saturated SE T1w sequences. Once endplate enhancement was observed on the T1 gadolinium-enhanced MR sequence, a second MRI examination (SE T1w sequence) was performed 24 h after USPIO administration (45 μmol Fe/kg). MR imaging was correlated with histopathological findings (macrophage immunostaining and Perls Prussian blue staining). On gadolinium-enhanced T1 sequences, a significant SNR increase in vertebral endplates was present in both groups without significant difference between the two groups (P = 0.26). On USPIO-enhanced T1 sequences, a significant SNR increase was only observed in the infection group (P = 0.03) with a significant difference in SNR between the infection and the sterile-inflammation groups (P = 0.002). Infected areas presented replacement of bone marrow by an intense macrophage infiltration, some being iron-loaded. Sterile inflammation showed a replacement of bone marrow by inflammatory tissue with only rare macrophages without any Perls blue staining. USPIO-enhanced MR imaging can distinguish infectious osteomyelitis from sterile vertebral inflammation due to different macrophage distributions in the two lesions. (orig.)

  14. Osseous Consolidation of an Aseptic Delayed Union of a Lower Leg Fracture after Parathyroid Hormone Therapy - A Case Report.

    The absence of osseous consolidation of a fracture within the normal time period is defined as delayed union or non-union. Both for the patient and from a socio-economic point of view, impaired fracture healing represents a major problem. Risk factors for a delayed fracture healing are insufficient immobilisation, poor adaptation of the fracture surfaces, interposition of soft tissue in the fracture gap, as well as circulation disturbances, metabolic disease, smoking and infections. In animal studies, a positive effect of parathyroid hormone (PTH) on fracture healing has been shown. PTH has a direct stimulatory effect on osteoblasts and osteoclasts. In addition, it appears to influence the effect of osseous growth factors. Few cases with the empiric off-label use of PTH that showed a tendency to support delayed or non-union fractures have been published. We report about a patient with a fracture of the lower leg and no osseous consolidation after 7 months. Four Months after therapy with 20 μg teriparatide per day for 8 weeks the fracture was consolidated and the patient had regained full and pain free weight bearing capacity of the leg with no reported side effects.

    We measured levels of pro-inflammatory cytokines in the cerebrospinal fluid (CSF) of patients with mumps meningitis, enteroviral echovirus 30 meningitis and children without central nervous system infection to investigate whether these molecules were involved in the pathogenesis of viral meningitis. The CSF was obtained from 62 children suspected with meningitis. These patients were classified to the mumps meningitis (n = 19), echovirus 30 meningitis (n = 22) and non-meningitis (n = 21) groups. The concentrations of interleukin-1 (IL-1), interleukin-1 soluble receptor type 2 (IL-1R2), interleukin-8 (IL-8), human interferon gamma (IFN-γ) and human tumour necrosis factor alpha (TNF-α) were determined by immunoassay. A significant increase was noted in the levels of IL-8, TNF-α and IL-1R2 in the CSF of both meningitis groups as compared to controls. The concentrations of IFN-γ and IL-1 differed significantly only between the mumps group and control. The levels of IL-1, IFN-γ and TNF-α were significantly higher in mumps meningitis when compared to the echovirus 30 group. Of all cytokines examined, only IFN-γ correlated with pleocytosis (r = 0.58) in the mumps meningitis group. The increased CSF cytokine levels are markers of meningeal inflammation, and each virus may cause a specific profile of the cytokine pattern.

    2013-04-01

    Full Text Available Background: The health-care professionals, particularly paramedics are exposed to bloodborne infections during medical rescue operations. The aim of this study was to assess knowledge of bloodborne infections, their prevention and interrupted routes of infection transmission among paramedics. Materials and Methods: The study comprised 220 paramedics employed in emergency departments and ambulance services. Material was collected using an anonymus questionnaire, developed for the purpose of this study. Results: As many as 80% of the surveyed people reported frequent contact with patients' blood; 65% of the paramedics before establishing the intravenous access palpates the conduct of the vein; 81% introduce peripheral venous catheter directly after disinfection of the skin; and 98% apply personal protection measures. Conclusions: The analysis of knowledge of asepsis and antisepsis of bloodborne infections among paramedics points to a series of shortcomings in their adequate preparation to reduce the effects of exposure to infectious material. However, it should be emphasized that people with higher education presented a higher level of knowledge than those with postsecondary vocational education. In the opinion of the study group mandatory training in the discussed area would prove to be the most effective method for reducing the number of bloodborne infections. Med Pr 2013;64(2:239–243

  8. Contamination control in HVAC systems for aseptic processing area. Part I: Case study of the airflow velocity in a unidirectional airflow workstation with computational fluid dynamics.

    Science.gov (United States)

    Ogawa, M

    2000-01-01

    A unidirectional airflow workstation for processing a sterile pharmaceutical product is required to be "Grade A," according to EU-GMP and WHO-GMP. These regulations have employed the wording of "laminar airflow" for unidirectional airflow, with an unclear definition given. This seems to have allowed many reports to describe discussion of airflow velocity only. The guidance values as to the velocity are expressed in various words of 90 ft/min, 0.45 m/sec, 0.3 m/sec, +/- 20%, or "homogeneous air speed." It has been also little clarified how variation in airflow velocity gives influences on contamination control of a workstation working with varying key characteristics, such as ceiling height, internal heat load, internal particle generation, etc. The present author has revealed following points from a case study using Computational Fluid Dynamics: the airflow characteristic in Grade A area shows no significant changes with varying the velocity of supplied airflow, and the particles generated from the operator will be exhausted outside Grade A area without contamination.

    1989-04-01

    25 patients suffering from femoral head necrosis in 30 hip joints were radiologically studied for an average of 11.6 years following intertrochanteric varus angulation osteotomy. Preoperatively only stages 2 and 3 according to Meyers were seen. The follow-up results could be distributed into 4 groups. At best the osteonecrosis was reconstructed within 6 to 9 years while the trabeculae started to become rearranged within 2 to 4 years. At worst, rapid destruction in absence of bony reaction was observed. The ability of the bone outside the osteonecrosis to react to changed circumstances following angulation osteotomy correlates with long-term results. This may indicate a general osteopathy even outside the necrotic area. (orig.).

  11. Vascularized osseous graft for scaphoid

    International Nuclear Information System (INIS)

    The most commonly used technique for treatment of pseudo-arthrosis of the scaphoid is osteo-synthesis with Kirschnet wires and cortical sponge grafts. Results reported by different teams using this procedure show no more than 90% osseous consolidation, especially in cases where vascularisation of the proximal fragment of the scaphoid is compromised. Here we present a series of ten cases of pseudo-arthrosis of the scaphoid, treated using a new surgical technique involving a vascularized osseous graft of the distal radius. Using this procedure we obtained 100% consolidation, with no complications either during the procedure or immediately post-operatively. Patients returned to work in week 15 on average. In 4 cases we observed discomfort in the area of the scar, which was successfully treated using local cortisone injection. The results obtained are very similar to those seen in the literature on the different techniques for vascularized osseous grafts for pseudo-arthrosis of the scaphoid

    Two cases of congenital defects of transverse processes of lumbar spine causing lumbalgia are described. The first one was produced by direct contact of the elongated processes with subsequent pseudoarthrosis. Hypertrophied processes caused stenosis around intervertebral foramen and irritated posterior neural branch in the second case. Surgical resection of the hypertrophied transverse processes has brought the cure. (author). 4 refs, 6 figs.

    1994-10-01

    We have performed dissection of the ITA using the CHAUX retractor in many patients. This retractor is a two-point sternal/IMA and valve retractor, with four sternal blades with individual and independent dual movement. The sliding sternal blade assemblies permit movement along the horizontal plane of the side arm. This retractor can be used for other types of cardiac surgery, as well. We obtained good results with its use for repair of distal aortic arch aneurysm. We conclude that this retractor is safe and useful for cardiac surgery.

  19. Computed tomography of the sternum and its articulations

    International Nuclear Information System (INIS)

    The chest wall presents diagnostic difficulties for both the clinician and the radiologist. Because of normal variations in anatomy and ossification, analysis of the sternal region can be particularly confusing. We reviewed the normal computed tomographie (CT) appearance of the sternum in 354 patients. Important normal sternal variants included cortical insharpness along the posterior aspect of the manubrium, lateral surfaces of the body, and at the sternal fibrocartilaginous articulations; soft tissue prominence at the junction of the sternum and costochondral cartilage; and bony sclerosis at the transitions from manubrium to body and from body to xiphoid. In seven patients with clinically significant sternal abnormality, key CT features were abnormal soft tissue mass (7/7), destruction or irregularity of the cortical contour (7/7), and abnormal increased attenuation of bone (1/7). CT should be the radiologic study of choice in patients with suspected abnormality of the sternum and its articulations. (orig.)

    Hypersensitivity to stainless steel sternal sutures are an uncommon occurrence. We present a case of such a patient who developed chronic tissue overgranulation over a sternotomy wound eight weeks post-operatively. Primary suspicion was infection, a more common complication however radiological and laboratory investigation showed otherwise. Conservative management provided limited ephemeral success. After ensuring adequate sternal bone healing, the sutures and granulation tissue were eventually surgically removed without complication and the reoperated wound healed well.

    2013-01-01

    Full Text Available In this single case study, we attempt to outline the possible effect of low-level laser therapy (LLLT on delayed wound healing and pain in chronic dehiscent sternotomy of a diabetic individual. The methods that were employed to evaluate changes pre and post irradiation were wound photography, wound area measurement, pressure ulcer scale of healing (PUSH, and visual analogue scale (VAS for pain. After irradiation, proliferation of healthy granulation tissue was observed with decrease in scores of PUSH for sternal dehiscence and VAS for bilateral shoulders and sternal dehiscence. We found that LLLT irradiation could be a novel method of treatment for chronic sternal dehiscence following coronary artery bypass grafting, as it augments wound healing with an early closure of the wound deficit. Hence, this might be translated into an early functional rehabilitation and decreased pain perception of an individual following surgical complication.

    Age and sex-related variations in sternum morphology may affect the thoracic injury tolerance. Male and female sternum size and shape variation was characterized for ages 0-100 from landmarks collected from 330 computed tomography scans. Homologous landmarks were analyzed using Procrustes superimposition to produce age and sex-specific functions of 3D-sternum morphology representing the combined size and shape variation and the isolated shape variation. Significant changes in the combined size and shape variation and isolated shape variation of the sternum were found to occur with age in both sexes. Sternal size increased from birth through age 30 and retained a similar size for ages 30-100. The manubrium expanded laterally from birth through age 30, becoming wider in relation to the sternal body. In infancy, the manubrium was 1.1-1.2 times the width of the sternal body and this width ratio increased to 1.6-1.8 for adults. The manubrium transformed from a circular shape in infancy to an oval shape in early childhood. The distal sternal body became wider in relation to the proximal sternal body from birth through age 30 and retained this characteristic throughout adulthood. The most dramatic changes in sternum morphology occur in childhood and young adulthood when the sternum is undergoing ossification. The lesser degree of ossification in the pediatric sternum may be partly responsible for the prevalence of thoracic organ injuries as opposed to thoracic skeletal injuries in pediatrics. Sternum fractures make up a larger portion of thoracic injury patterns in adults with fully ossified sternums. The lack of substantial size or shape changes in the sternum from age 30-100 suggests that the increased incidence of sternal fracture seen in the elderly may be due to cortical thickness or bone mineral density changes in the sternum as opposed to morphological changes.

  2. Chronic Osteomyelitis in Sternum Mimicking Bone Metastasis of Lung Cancer Patient

    International Nuclear Information System (INIS)

    Primary sternal osteomyelitis without predisposing factors is a rare condition, and it is hardly differentiated from metastatic bone tumor especially in patient with the history of primary malignancy because osteomyelitis shares frequently common findings with metastatic bone lesion on 18F-FDG PET and bone scan. Although there have been several publications of primary osteomyelitis mimicking bone metastasis in the spine or extremities, we report a case of primary sternal osteomyelitis in the patient with lung cancer, which has, to our knowledge, not been reported before

    MOMO syndrome, a condition described in three earlier patients, is a constellation of macrosomia, obesity, macrocephaly, and ocular abnormalities as the main findings. We report a 6-year-old child with these findings as well as significant developmental issues, delayed bone age, clavicular pseudoarthrosis, and straight femurs. We believe that this child should be considered as having MOMO syndrome. Careful consideration of his facial features shows some overlap with Kabuki syndrome. Description of this case may help to better elucidate the clinical features of MOMO syndrome.

    With the aging population, there is a rising prevalence of degenerative spinal deformity and need of surgical care for these patients. Surgical treatment for adult spinal deformity (ASD) is often fraught with a high rate of complications. Minimally invasive surgery (MIS) has for the past decade been adopted by spine surgeons to treat ASD in the hopes of reducing access-related morbidity and perioperative complications. The benefits of MIS approach in general and recent development of MIS techniques to avoid long-term complications such as pseudoarthrosis or proximal junctional kyphosis are reviewed. PMID:27411527

    2012-02-01

    Rheumatoid arthritis is an autoimmune disease which frequently affects the ankle and foot. End stage ankle arthritis from rheumatic disease is commonly managed by the established practice of ankle arthrodesis. Among the adverse sequelae causing pain following this surgery is infection, pseudo-arthrosis and non-union. Stress fracture of the distal third is a recognised but unusual cause of pain of tibia following ankle arthrodesis. The authors\\' present three patients with rheumatoid arthritis who sustained a stress fracture of the distal tibia following arthrodesis, and discuss the contributing factors and highlight the need for orthopaedic surgeons to be suspicious of this complication post surgery.

  8. Scintigraphy of spinal disorders in adolescents

    International Nuclear Information System (INIS)

    Bone scintigraphy in adolescents is useful in helping to differentiate between developmental (atypical lumbar Scheuermann disease), infectious (discitis, osteomyelitis), neoplastic (osteoid osteoma, osteoblastoma), and traumatic (occult fractures, spondylolysis, pseudoarthrosis) disease of the spine. Double-phase (blood pool, delayed images) scintigraphy can characterize the pattern (i.e., linear in fracture, ovoid in nidus of osteoid osteoma). Single-photon emission computed tomography (SPECT) can be helpful in detecting the subtle presence of stress reaction (spondylolyses) not noted on routine planar scintigraphy and radiography. Bone scintigraphy is most beneficial when correlated with other imaging modalities in refining the diagnosis of spinal diseases. (orig.)

    Full Text Available Objective: Enterovirus 71(EV 71 causes wide spectrum of infections ranging from asymptomatic conditions to clinical syndromes like diarrhea, rash, hand-foot-and mouth disease (HFMD, herpangina, aseptic meningitis, encephalitis, myocarditis, acute flaccid paralysis, bulbar and brainstem encephalitis Guillain Barre syndrome, pulmonary haemorrhage. This study deals with an outbreak of aseptic meningitis in children caused by EV 71 virus. Methods: The authors report an outbreak of aseptic meningitis in children in and around Calicut in June 2008. Clinical and laboratory study was done in collaboration with National Centre for Disease Control, New Delhi. 149 children with aseptic meningitis were studied and followed up from June 2008 to May 2009. Result: All children had clinical features suggestive of aseptic meningitis and serology showed the rising antibody titre against EV 71 virus infection. CSF analysis also showed four fold rise in antibodies in one and ≥ 1:2 neutralising antibodies titer against EV- 71 in four samples indicating meningitis due to EV-71. Conclusion: EV 71 was identified as the causative agent of the outbreak of aseptic meningitis in the study and the fact that the EV 71 infection has evolved from minor illness like HFMD to major illness like aseptic meningitis from the same locality is truly alarming.

    International Nuclear Information System (INIS)

    Hip pain due to aseptic necrosis of the femoral head was the first clinical manifestation of chronic myelogenous leukemia in a 9-year-old white female. An erroneous diagnosis of rheumatoid arthritis was first entertained. Physical examination showed splenomegaly, complete blood count revealed leucocytosis of 359 000. The initial radiograph of the involved hip was negative. Biopsy revealed aseptic necrosis of the femoral head. Chronic myelogenous leukemia (CML) was diagnosed on the basis of the peripheral blood smear and bone marrow biopsy. Two months later, radiograph, radionuclide bone scan, and magnetic resonance imaging (MR) of the involved hip were positive for aseptic necrosis of the femoral head. (orig.)

    In contrast to widely-reported sternal insufficiency fractures, stress fractures of the sternum from overuse are extremely rare. Of the 5 cases of sternal stress fracture published in the English-language medical literature, 3 were in the sternal body and only 2 were in the manubrium. We describe two cases of manubrial stress fracture related to golf and weightlifting, and present the first report of the MR findings of this injury. In each of these cases, the onset of pain was atraumatic, insidious, and associated with increased frequency of athletic activity. Imaging was obtained because of clinical diagnostic uncertainty. On MRI, each patient had a sagittally oriented stress fracture of the lateral manubrium adjacent to the first rib synchondrosis. Both patients had resolution of pain after a period of rest, with subsequent successful return to their respective activities. One patient had a follow-up MRI, which showed resolution of the manubrial marrow edema and fracture line. Based on the sternal anatomy and MR findings, we hypothesize that this rare injury might be caused by repetitive torque of the muscle forces on the first costal cartilage and manubrium, and propose that MRI might be an effective means of diagnosing manubrial stress fracture.

    Conclusions: Large glandular specimen increases the risk of NAC necrosis. The degree of ptosis and the distance between the sternal notch and the NAC have no significant impact on necrotic complications in NSM. To reduce the necrotic complications in large breast after NSM, reconstruction should better be performed with autologous flap or slow skin expansion using the expander technique.

    The respiratory rate (RR) is a clinically important vital sign and is a frequently used parameter in the general hospital wards. In current clinical practice, the monitoring of the RR is by manual count of the chest movement for one minute. This paper addresses a new approach where the respiratory rate is extracted using photoplethysmography (PPG) on the chest bone (sternum). Sternal PPG signals were acquired from 10 healthy subjects resting in a supine position. As reference signals, finger PPG, electrocardiogram (ECG), and capnography were simultaneously recorded during spontaneous and paced breathing. The sternal PPG signals were then compared with the reference signals in terms of Bland-Altman analysis, the power spectrum analysis and the magnitude squared coherence. The Bland-Altman analysis showed an average bias of 0.21 breaths/min between RR extracted from sternal PPG and capnography. The respiratory power content at the sternum was 78.8 (38) % in terms of the median and (the interquartile range). The cardiac content was 19 (18.4) % within the cardiac region. The results from the magnitude squared coherence analysis was 0.97 (0.09) in the respiratory region (6 to 27 breaths/min) and 0.98 (0.01) in the cardiac pulse region (30-120 beats/min). This preliminary study demonstrates the possibility of monitoring the RR from sternal PPG on a healthy group of subjects during rest. PMID:26737798

    Full Text Available Objective of this report is to observe and report unusual pattern of origin of sternal and clavicular heads of Sternocleidomastoid (SCM. An embryological insight into the possible causes for present anomaly is elucidated. The neck region of an adult male cadaver during gross anatomy teaching program. An abnormal Sternocleidomastoid (SCM was observed while dissecting the neck region of an adult. Additional clavicular head of SCM muscle were found on the right side. The accessory clavicular head coursed deep to the sternal head whereas the some fibres of main clavicular head joined the accessory belly and together they fused with the main sternal head of SCM. There was another slip arising from sternal head and merge with deep cervical fascia near base of mandible. The topographical anatomy of SCM is extremely important, particularly because it serves as a useful surgical landmark and its relation to crucial neuro-vascular structures of the neck. The usage of SCM in reconstruction operations for covering defects is discussed. A detailed knowledge of the anatomy of SCM proves vital for radiological studies of the neck.

    Abstract Background To report our experience, with Deep mediastinal wound infections (DMWI). Emphasis was given to the management of deep infections with omental flaps Methods From February 2000 to October 2007, out of 3896 cardiac surgery patients (prospective data collection) 120 pts (3.02%) developed sternal wound infections. There were 104 males & 16 females; (73.7%) CABG, (13.5%) Valves & (9.32%) CABG and Valve. Results Superficial sternal wound infection detected in 68 patients (1.75%) and fifty-two patients (1.34%) developed DMWI. The incremental risk factors for development of DMWI were: Diabetes (OR = 3.62, CI = 1.2-10.98), Pre Op Creatinine > 200 μmol\\/l (OR = 3.33, CI = 1.14-9.7) and Prolong ventilation (OR = 4.16, CI = 1.73-9.98). Overall mortality for the DMWI was 9.3% and the specific mortality of the omental flap group was 8.3%. 19% of the "DMWI group", developed complications: hematoma 6%, partial flap loss 3.0%, wound dehiscence 5.3%. Mean Hospital Stay: 59 ± 21.5 days. Conclusion Post cardiac surgery sternal wound complications remain challenging. The role of multidisciplinary approach is fundamental, as is the importance of an aggressive early wound exploration especially for deep sternal infections.

    Performing a redo-sternotomy when a mammary artery graft is patent can be rather difficult. We previously reported a redo-sternotomy technique involving direct visualization with a retrosternal dissection (DR) method using a Kent's retractor. The DR method in detail is as follows: 1) A midline skin incision is extended to the abdomen about 5 cm. 2) The bilateral costal arches are divided from the rectal muscle. 3). A pair of retractors is placed under the costal arch. 4) A stainless steel wire is applied to the previous sternal wire at the center of the sternum. 5) The retractor and sternal wire are lifted up using the Kent's retractor to widen the retrosternal space. 6) The sternum and sub-sternal tissue are carefully divided using an electronic scalpel or metal retractor with an entirely sternal length. 7) Routine sternotomy is performed using a Stryker. Herein, we report a patient who had undergone cardiac surgery, coronary artery bypass grafting (CABG), using a left internal mammary artery and mitral annuloplasty 2 years previously, and then developed mitral regurgitation caused by infectious endocarditis. He successfully underwent redo-sternotomy and mitral valve replacement using the DR method. In a patient with a patent internal mammary artery, the DR method greatly reduces the risk of graft injury.

    Full Text Available Introduction: Surgical treatment of spinal deformity resulting from neurofibromatosis (NF is a major challenge for orthopedic spine surgeons. There are several problems and complications including pseudoarthrosis and cure progress despite treatment. Progressive kyphoscoliosis is the most important spinal deformity. The present study aims to evaluate surgical treatment results in severe spinal involvement cases. Methods: This analytical a-descriptive study evaluated 20 patients with NF, severe scoliosis and kyphosis (up to 50° hospitalized and treated at our center during the past 10 years. The treatment failure rate and complications were studied. Results: In this study, 20 cases with NF and kyphoscoliosis with the mean age of 13.00 ± 7.18 years were studied. These case series were consisted of 13 (65% males and 7 (35% females. Overall treatment failure was 45%. However, it was 55% of failure happened in posterior fusion alone. Failure rate was reported 36% in the combined anterior and posterior fusion and mainly seen in younger than 8-years children. Surgical complications were found in 20% with pseudoarthrosis as the most common one. There were no infections and neurological complications. Statistically, there was a significant negative relation between age and curve progression in scoliosis and kyphosis during the 2 years follow-up period. There was not any significant difference between genders considering curvature progress. Conclusion: The combined anterior and posterior fusion is probably more effective treatment, especially at early ages when more aggressive treatment is required since it reduces the treatment failure possibility.

    Introduction. Congenital insensitivity to pain and anhidrosis (CIPA) or hereditary sensory and autonomic neuropathy type IV is an extremely rare syndrome. Three clinical findings define the syndrome: insensitivity to pain, impossibility to sweat, and mental retardation. This pathology is caused by a genetic mutation in the NTRK1 gene, which encodes a tyrosine receptor (TrkA) for nerve growth factor (NGF). Methods. The consultation of a child female in our center with CIPA and a tibia fracture in pseudoarthrosis encouraged us to carefully review literature and examine the therapeutic possibilities. A thorough review of literature published in Pubmed was done about CIPA and other connected medical issues mentioned in the paper. Conclusions. The therapeutic approach of CIPA remains unclear. The preventive approach remains the only possible treatment of CIPA. We propose two new important concepts in the therapeutic approach for these patients: (1) early surgical treatment for long bone fractures to prevent pseudoarthrosis and to allow early weight bearing, decreasing the risk of further osteopenia, and (2) bisphosphonates to avoid the progression of osteopenia and to reduce the number of consecutive fractures.

    A bioactive and bioresorbable scaffold fabricated from medical grade poly (epsilon-caprolactone) and incorporating 20% beta-tricalcium phosphate (mPCL-TCP) was recently developed for bone regeneration at load bearing sites. In the present study, we aimed to evaluate bone ingrowth into mPCL-TCP in a large animal model of lumbar interbody fusion. Six pigs underwent a 2-level (L3/4; L5/6) anterior lumbar interbody fusion (ALIF) implanted with mPCL-TCP + 0.6 mg rhBMP-2 as treatment group while four other pigs implanted with autogenous bone graft served as control. Computed tomographic scanning and histology revealed complete defect bridging in all (100%) specimen from the treatment group as early as 3 months. Histological evidence of continuing bone remodeling and maturation was observed at 6 months. In the control group, only partial bridging was observed at 3 months and only 50% of segments in this group showed complete defect bridging at 6 months. Furthermore, 25% of segments in the control group showed evidence of graft fracture, resorption and pseudoarthrosis. In contrast, no evidence of graft fractures, pseudoarthrosis or foreign body reaction was observed in the treatment group. These results reveal that mPCL-TCP scaffolds could act as bone graft substitutes by providing a suitable environment for bone regeneration in a dynamic load bearing setting such as in a porcine model of interbody spine fusion.

    2015-03-01

    Segmentation of the sternum in medical images is of clinical significance as it frequently serves as a stable reference to image registration and segmentation of other organs in the chest region. In this paper we present a fully automated algorithm to segment the sternum in low-dose chest CT images (LDCT). The proposed algorithm first locates an axial seed slice and then segments the sternum cross section on the seed slice by matching a rectangle model. Furthermore, it tracks and segments the complete sternum in the cranial and caudal direction respectively through sequential axial slices starting from the seed slice. The cross section on each axial slice is segmented using score functions that are designed to have local maxima at the boundaries of the sternum. Finally, the sternal angle is localized. The algorithm is designed to be specifically robust with respect to cartilage calcifications and to accommodate the high noise levels encountered with LDCT images. Segmentation of 351 cases from public datasets was evaluated visually with only 1 failing to produce a usable segmentation. 87.2% of the 351 images have good segmentation and 12.5% have acceptable segmentation. The sternal body segmentation and the localization of the sternal angle and the vertical extents of the sternum were also evaluated quantitatively for 25 good cases and 25 acceptable cases. The overall weighted mean DC of 0.897 and weighted mean distance error of 2.88 mm demonstrate that the algorithm achieves encouraging performance in both segmenting the sternal body and localizing the sternal angle.

    A 55-year-old woman was admitted for orthotopic heart transplantation. Her medical history was notable for multiple cardiovascular problems, including ischemic cardiomyopathy that necessitated circulatory support with a left ventricular assist device. Five weeks after undergoing orthotopic heart transplantation, she developed Aspergillus calidoustus mediastinitis, for which she underwent a prolonged course of antifungal treatment that comprised (in sequence) posaconazole for 11 days, voriconazole for 10 days, and amphotericin B for 42 days. During this period, she also underwent repeated mediastinal drainage and sternal débridement, followed by sternal wiring and coverage with bilateral pectoralis advancement flaps. Four months postoperatively, she was discharged from the hospital with a successfully controlled infection and a healed sternum. To our knowledge, only 3 previous cases of Aspergillus mediastinitis after orthotopic heart transplantation have been reported in the literature, none of which was Aspergillus calidoustus.

    Full Text Available Abstract Deep sternal infections, also known as poststernotomy mediastinitis, are a rare but often fatal complication in cardiac surgery. They are a cause of increased morbidity and mortality and have a significant socioeconomic aspect concerning the health system. Negative pressure wound therapy (NPWT followed by muscular pectoralis plasty is a quite new technique for the treatment of mediastinitis after sternotomy. Although it could be demonstrated that this technique is at least as safe and reliable as other techniques for the therapy of deep sternal infections, complications are not absent. We report about our experiences and complications using this therapy in a set of 54 patients out of 3668 patients undergoing cardiac surgery in our institution between January 2005 and April 2007.

    2011-09-01

    Full Text Available Pectus excavatum (PE is the most commonly encountered chest wall deformity which comprises one out of 1,000 live births. Depression of the anterior chest wall due to posterior angulation of the sternum and costal cartilages results in compression of internal thoracic organs as well as aesthetically unpleasant appearance. Multiple surgical techniques have been developed to correct this condition. Ravitch procedure, the technique including the excision of all deformed costal cartilages, division of intercostals bundles from the sternum, and transverse sternal osteotomy, was proposed in 1949 and most widely applied until recently. The Wada technique, principally sternal turnover, has been an alternative procedure. Those invasive techniques involve tedious and bloody operations resulted in a permanent defect of costal cartilages or contracture of the chest wall. Most importantly, a large, unsightly operative scar at the anterior chest is aesthetically dissatisfying. In this study “Minimally Invasive Surgery for Pectus Excavatum: Park Technique” was explained.

    A young Somali immigrant presents with a two-year history of a large, firm, painful right anterolateral chest wall sternal mass. The patient denied any history of trauma or infection at the site and did not have a fever, erythematous lesion at the site, clubbing, or lymphadenopathy. A lateral chest radiograph demonstrated a low density mass isolated to the subcutaneous soft tissue overlying the sternum, ribs and clavicle. Computed tomography(CT) with contrast demonstrated a cystic lesion in the right anterolateral chest wall deep to the pectoralis muscle. Enhanced CT of the chest demonstrated sclerosis and destruction of the rib and costochondral joint and manubrio-sternal joint narrowing. Ultrasound-guided biopsy and aspiration returned 500 cc of purulent, cloudy yellow, foul-smelling fluid. Acidfact bacilli stain and the nucleic acid amplification test identified and confirmed Mycobacterium tuberculosis. A diagnosis of tuberculous osteomyelitis/septic arthritis was made and antibiotic coverage for tuberculosis was initiated.

  4. CONGENITAL FORAMEN IN THE BODY OF STERNUM

    Directory of Open Access Journals (Sweden)

    Bermio V.S.

    2014-09-01

    Full Text Available Background:The knowledge of sternal variations is important as this bone is usually chosen for bone marrow aspiration.One such developmental anomaly is the presence of foramina, of varying dimensions, in manubrium or body or xiphisternum.Usually, the defect occurs in the lower third of sternum,in the body, as a single midline foramen (oval or round and is usually asymptomatic and can be demonstrated only by CT scanning. The observation and knowledge of these foramina are of utmost importance in clinical, forensic and acupuncture techniques.Hence, this observation could be a useful one. Materials and methods: During a routine osteology class in the Department of Anatomy,Kanyakumari Government Medical College,an adult sternum of unknown sex and age was found to have a foramen in the lower part of body at the level of articular facets for fifth costal cartilages. Results:The following observations were made: (1The sternum presented an oval foramen in the lower part of the body. (2 It was located in midline at the junction between third and fourth sternebrae.(3 Its margins were smooth and measured 5mm×6mm. Conclusion:Embryologically,sternum is formed by the craniocaudal fusion of two sternal bars,which are condensations of mesenchymal tissue which get converted to pre-cartilage before fusion. Any defect in this fusion may cause cleft sternum or sternal foramina(single or multiple. The single sternal foramen presented here could have clinical implications. Its knowledge helps in preventing fatal cardiac tamponade following needle insertion during bone marrow biopsy or acupuncture performed in this region. Forensic misinterpretation of this defect is also possible.

    1992-01-01

    The diagnostic accuracy of exercise electrocardiography has been improved by incorporation of R-wave gain factor to correct the measured ST-segment changes. If marked changes in R-wave amplitude occur in individual patients during cardiac operations, a similar gain factor correction may improve the intraoperative diagnosis of myocardial ischemia. This investigation was designed to determine the frequency and magnitude of intraoperative V5 R-wave amplitude changes during cardiac operations. Electrocardiograms were recorded from 83 patients while patients were awake, anesthetized (baseline), after placement of the Favaloro and Canadian sternal retractors, and at end-operation. Compared with baseline values, placement of the Canadian sternal retractor was associated with a reduction in V5 R-wave amplitude from 15 +/- 1 to 10 +/- 1 mm (mean +/- SEM), in V5 S-wave amplitude from 3.5 +/- 0.4 to 1.7 +/- 0.3 mm, and in absolute ST-segment deviation from 0.50 +/- 0.04 to 0.39 +/- 0.05 mm. Changes in V5 R-wave amplitude were correlated with changes in ST-segment deviation in patients with baseline ST-segment deviations greater than or equal to 0.5 mm (r = 0.55, P = 0.0004, n = 37). Changes associated with the Favaloro retractor and the respiratory cycle were less marked. However, the V5 R-wave amplitude was decreased from 15 +/- 1 to 9 +/- 1 mm at end-operation. In conclusion, sternal spreading with the Canadian retractor was associated with marked reductions in V5 R- and S-wave amplitudes and ST-segment deviations. Marked changes in V5 R-wave amplitude persisted after sternal closure.(ABSTRACT TRUNCATED AT 250 WORDS)

    The quality and duration of anaesthesia, cardiorespiratory effects and recovery characteristics of a morphine, medetomidine, ketamine (MMK) drug combination were determined in cats. Six healthy, adult female cats were administered 0.2 mg/kg morphine sulphate, 60 microg/kg medetomidine hydrochloride, and 5 mg/kg ketamine hydrochloride intramuscularly. Atipamezole was administered intramuscularly at 120 min after MMK administration. Time to lateral recumbency, intubation, extubation and sternal recumbency were recorded. Cardiorespiratory variables and response to a noxious stimulus were recorded before and at 3 min and 10 min increments after drug administration until sternal recumbency. The time to lateral recumbency and intubation were 1.9+/-1.2 and 4.3+/-1.2 min, respectively. Body temperature and haemoglobin saturation with oxygen remained unchanged compared to baseline values throughout anaesthesia. Respiratory rate, tidal volume, minute volume, heart rate, and blood pressure were significantly decreased during anaesthesia compared to baseline values. One cat met criteria for hypotension (systolic blood pressure cat remained non-responsive to noxious stimuli from 3 to 120 min. Time to extubation and sternal recumbency following atipamezole were 2.9+/-1.1 and 4.7+/-1.0 min, respectively. MMK drug combination produced excellent short-term anaesthesia and analgesia with minimal cardiopulmonary depression. Anaesthesia lasted for at least 120 min in all but one cat and was effectively reversed by atipamezole. PMID:17198759

    Leaving the median sternotomy wound open following cardiac surgery is employed to avoid cardiovascular compression. Horizontal struts can be used. Radiologists interpreting portable radiographs might be unaware of the open median sternotomy (OMS). To describe the frequency of radiographic signs of OMS and to increase awareness among radiologists to prevent misdiagnosis of pneumothorax and pneumomediastinum. Radiographs of 41 infants (17 girls/24 boys) with OMS were studied (age range 2 days to 8 months, mean 33 days). Central lucency and sternal edges were noted. Interclavicular distances before and after sternotomy were compared. Central lucency was seen in 25/41 (61%) children. Sternal struts were apparent in 27 (66%). In 14 without struts, central lucency was present in 8 (57%). In 27 children with struts, central lucency was present in 17 (63%) and absent in 10 (37%). Split sternal centers were identified in 6/41 (15%). The mean interclavicular distance was 23.5 mm (SD = 4.39) before sternotomy and 38.2 mm (SD = 7.0 mm) after sternotomy (P < 0.001). OMS has characteristic signs in the majority of cases. Recognition of these findings is useful and can prevent misinterpretation. (orig.)

    When not diagnosed early and managed appropriately, common musculoskeletal injuries may result in long-term disabling conditions. Anterior cruciate ligament tears are some of the most common knee ligament injuries. Slipped capital femoral epiphysis may present with little or no hip pain, and subtle or absent physical and radiographic findings. Femoral neck stress fractures, if left untreated, may result in avascular necrosis, refractures and pseudoarthrosis. A delay in diagnosis of scaphoid fractures may cause early wrist arthrosis if nonunion results. Ulnar collateral ligament tears are a frequently overlooked injury in skiers. The diagnosis of Achilles tendon rupture is missed as often as 25 percent of the time. Posterior tibial tendon tears may result in fixed bony planus if diagnosis is delayed, necessitating hindfoot fusion rather than simple soft tissue repair. Family physicians should be familiar with the initial assessment of these conditions and, when appropriate, refer patients promptly to an orthopedic surgeon. PMID:9456991

    2011-06-01

    Full Text Available Neurofibromatosis (NF is divided into two types, NF type 1 and NF type 2. Optic nerve gliomas have a high degree of association with NF type 1. NF 2, less commonly seen, is a complex of cutaneous and deep neural tumors. It is an autosomal dominant familial disorder in which CNS is affected in about 15% of the cases. Bilateral acoustic neuromas are pathognomonic of NF type 2 which may be associated with meningiomas or ependymomas.Typical clinical manifestations of neurofibromatosis are cafe-au-lait spots and multiple cutaneoustumors. There is bone involvement as scoliosis, pseudoarthrosis of long bones, scalloping of vertebral bodies, abnormal rib tubulation and defective ossification of the skull. Extraskeletal anifestations of neurofibromatosis include optic nerve gliomas, pheochromocytoma,aneurysms of cerebral and renal arteries, acoustic neurilemmoma and superficial skin nodular neurofibromas.Here, we intend to present images of several cases of neurofibromatosis with different patternsof body involvement.

    Lumbar interbody fusion represents an effective surgical intervention for patients with lumbar degenerative diseases, spondylolisthesis, disc herniation, pseudoarthrosis and spinal deformities. Traditionally, conventional open anterior lumbar interbody fusion and posterior/transforaminal lumbar interbody fusion techniques have been employed with excellent results, but each with their own advantages and caveats. Most recently, the antero-oblique trajectory has been introduced, providing yet another corridor to access the lumbar spine. Termed the oblique lumbar interbody fusion, this approach accesses the spine between the anterior vessels and psoas muscles, avoiding both sets of structures to allow efficient clearance of the disc space and application of a large interbody device to afford distraction for foraminal decompression and endplate preparation for rapid and thorough fusion. This review aims to summarize the early clinical results and complications of this new technique and discusses potential future directions of research. PMID:27349468

    Isolated coronal fractures of femoral condyle are rare in adults and nonunion of Hoffa fracture is reported only a few times in the literature. We analyzed six cases of nonunion of Hoffa fractures over a period of three years. Three patients were treated conservatively and three patients had fixation failures. Delay of presentation was 2 months to one year. Treatment protocol consisted of open reduction, excision of pseudoarthrosis, bone grafting and internal fixation along with knee arthrolysis. Union was achieved in all patients at mean 16 weeks. The treatment of nonunion of Hoffa fractures requires careful preoperative planning and meticulous surgical technique. The literature regarding the controversies in fracture management and surgical technique are reviewed.

  15. The significance of removing ruptured intervertebral discs for interbody fusion in treating thoracic or lumbar type B and C spinal injuries through a one-stage posterior approach.

    Qian-Shi Zhang

    Full Text Available OBJECTIVES: To identify the negative effect on treatment results of reserving damaged intervertebral discs when treating type B and type C spinal fracture-dislocations through a one-stage posterior approach. METHODS: This is a retrospective review of 53 consecutive patients who were treated in our spine surgery center from January 2005 to May 2012 due to severe thoracolumbar spinal fracture-dislocation. The patients in Group A (24 patients underwent long-segment instrumentation laminectomy with pedicle screw-rod fixators for neural decompression. In Group B (29 patients, the patients underwent long-segment instrumentation laminectomy with pedicle screw-rod fixators for neural decompression evacuating of the ruptured disc and inserting of a bone graft into the evacuated disc space for interbody fusion. The mean time between injury and operation was 4.1 days (range 2-15 days. The clinical, radiologic and complication outcomes were analyzed retrospectively. RESULTS: Periodic follow-ups were carried out until an affirmative union or treatment failure took place. A progressive kyphosis angle larger than 10°, loss of disc height, pseudoarthrosis, recurrence of dislocation or subluxation, or instrument failure before fusion were considered treatment failures. Treatment failures were detected in 13 cases in Group A (failure rate was 54.2%. In Group B, there were 28 cases in which definitive bone fusion was demonstrated on CT scans, and CT scans of the other cases demonstrated undefined pseudoarthrosis without hardware failure. There were statistically significant differences between the two groups (p0.05 Fisher's exact test. CONCLUSION: Intervertebral disc damage is a common characteristic in type B and C spinal fracture-dislocation injuries. The damaged intervertebral disc should be removed and substituted with a bone graft because reserving the damaged disc in situ increases the risk of treatment failure.

  16. Nuss bar procedure: past, present and future

    2016-01-01

    Repair of pectus excavatum began at the beginning of the 20th century before endotracheal intubation was standard practice. Surgeons therefore developed techniques that corrected the deformity using an open procedure via the anterior chest wall. Initial techniques were unsatisfactory, but by the 1930s the partial rib resection and sternal osteotomy technique had been developed and was used in combination with external traction post-operatively to prevent the sternum from sinking back into the chest. In 1949, Ravitch recommended complete resection of the costal cartilages and complete mobilization of the sternum without external traction, and in 1961 Adkins and Blades introduced the concept of a substernal strut for sternal support. The wide resection resulted in a very rigid anterior chest wall, and in some instances, the development of asphyxiating chondrodystrophy. The primary care physicians therefore became reluctant to refer the patients for repair. In 1987, Nuss developed a minimally invasive technique that required no cartilage or sternal resection and relied only on internal bracing by means of a sub-sternal bar, which is inserted into the chest through two lateral thoracic incisions and guided across the mediastinum with the help of thoracoscopy. After publication of the procedure in 1998, it became widely accepted and a flood of new patients suddenly started to appear, which allowed for rapid improvements and modifications of the technique. New instruments were developed specifically for the procedure, complications were recognized, and the steps taken to prevent them included the development of a stabilizer and the use of pericostal sutures to prevent bar displacement. Various options were developed for sternal elevation prior to mediastinal dissection to prevent injury to the mediastinal structures, allergy testing was implemented, and pain management improved. The increased number of patients coming for repair permitted studies of cardiopulmonary

  17. Effect of Deinococcus radiodurans on uptake of 134Cs by Brassica oleracea

    International Nuclear Information System (INIS)

    Deinococcus radiodurans was inoculated into the soil which was spiked with 134Cs to investigate its effect on chemical speciation of 134Cs. The relationship between chemical speciation of 134Cs and its absorbtion capacity by cabbage (Brassica oleracea) in the presence of D. radiodurans was also investigated. The results showed that an increase of 28.64%-38.17 % in content of 134Cs in residual phase was observed with presence of D. radiodurans in comparison with the aseptic control. The amounts of radiocesium uptaken by cabbage were about 12100Bq/g under aseptic conditions, however, which were about 8500Bq/g with the presence of D. radiodurans. The proportion of 134Cs taken up by cabbage decreased about 29% in comparison with the aseptic control. The chemical speciation could be influenced by D. radiodurans so that its uptake by plants could be reduced. (authors)

    Presented are case studies of 3 patients with aseptic meninogencephalitis occurring after returning from the Mediterranean tourist regions. None of the infectious agents common in aseptic neuroinfections in the Czech Republic was detected in the patients. Serological tests showed that in each case, the illness was caused by Toscana virus, a phlebovirus belonging to the family Bunyaviridae. The virus is transmitted by tiny biting insects of the genus Phlebotomus commonly present in the Mediterranean area. The course of the disease was mild to moderate and all the patients recovered without sequelae. These case reports document the fact that this arbovirus should be considered in the differential diagnosis of patients with aseptic neuroinfections returning from endemic areas of this virus.

    The larvae of musca domestica were put in use to discard the dead tissue of a case of severe burn. A total of 50 000 aseptic maggots were put onto the infective wound surface, and aseptic dressings overlaid the surface. Three days later, another 20 000 maggots were put onto the wound for the second therapy. After twice maggot debridement, most necrotic muscle tissues of the wound were cleaned up, and eventually fresh granulation tissue grew and later the wound was covered and healed by 3 times of skin grafting. The result demonstrates that maggot therapy is safe and effective with no adverse complications except pain. PMID:22480679

    Full Text Available Chronic aseptic meningitis is a rare manifestation of systemic lupus erythematosus (SLE. Apart from immunological causes and drugs, the aseptic meningitis group can include some unidentified viral infections that cannot be detected by routine microbiological testing. It is imperative to do complete cerebrospinal fluid (CSF workup before implicating the symptoms to disease activity or drugs, as untreated infections cause significant mortality in SLE. We present a case of young female with SLE who presented with chronic meningitis of an uncommon etiology.

    2013-01-01

    The patterns of complexity of the male and female sexual openings in Brachyura, which have been the source of uncertainties and conflicting opinions, are documented, together with a study of the morphologies of the coxal and sternal gonopores in both sexes, penises, spermathecae, and gonopods. The vulvae, male gonopores and penises are described among selected taxa of Eubrachyura, and their function and evolution examined in the context of a wide variety of mating behaviours. The location of female and male gonopores, the condition of the penis (coxal and sternal openings and modalities of protection), and related configurations of thoracic sternites 7 and 8, which are modified by the intercalation of a wide sternal part (thoracic sternites 7 and 8) during carcinisation, show evidence of deep homology. They represent taxonomic criteria at all ranks of the family-series and may be used to test lineages. Of particular significance are the consequences of the posterior expansion of the thoracic sternum, which influences the condition, shape, and sclerotisation of the penis, and its emergence from coxal (heterotreme) to coxo-sternal, which is actually still coxal (heterotreme), in contrast to a sternal emergence (thoracotreme). The heterotreme-thoracotreme distinction results from two different trajectories of the vas deferens and its ejaculatory duct via the P5 coxa (Heterotremata) or through the thoracic sternum (Thoracotremata). Dissections of males of several families have demonstrated that this major difference not only affects the external surface (perforation of the coxa or the sternum by the ejaculatory duct) but also the internal anatomy. There is no evidence for an ejaculatory duct passing through the articular membrane between the P5 coxa and the thoracic sternum in any Brachyura, even when the sternal male gonopore is very close to the P5 coxa. Trends towards the coxo-sternal condition are exemplified by multistate characters, varying from a shallow

Methods: Five pieces of banana leaf, 2 x 2 cm in size, were cultured separately in blood agar as follows: One piece was heated over a flame and one was soaked in boiling water and one was autoclaved. Methylated spirit was applied over one piece and ignited. One piece was placed on the media, ′as is.′ The Petri dishes were incubated examined after 48 h. Results: All the pieces except the autoclaved specimen of the leaf grew coagulase-negative staphylococci (CONS when aseptic precautions were not maintained and aerobic spore bearers when all aseptic measures were subsequently instituted during the procedure. Conclusion: We recommend measures to prevent possible transmission of bacterial infection by the leaf. Autoclaved and aseptically handled banana leaves may be used to reduce chance of infection in the treatment of TEN.

    International Nuclear Information System (INIS)

    Objective: To investigate the design of the interventional operating room that can meet the needs of modern DSA operation, and the overall arrangement of the hybrid operating room should be reasonable, practical and perspective. Methods: The experience and understanding obtained from the designing and planning of the new Building of Radiology and Surgery in authors' hospital were summarized. In order to meet the requirements of aseptic surgical practices and a full-featured hybrid operating room the following factors should be carefully and synthetically taken into account: the room size, the functional sub-areas, the operational procedures, the aseptic specification, etc. Results: The sufficient verification and scientific design were the important link for building a hybrid operating room. It could provide the surgeons and interventional physicians with more alternative operating methods and it could represent the development trend of medical technology. Conclusion: When planning and designing a new DSA operating room, various factors related to the interventional procedures, such as the room size, the functional sub-areas, the operational procedures and the aseptic specification, should be carefully and synthetically taken into account. The standard of aseptic procedure must be strictly complied with and the various functional sub-areas need to be rationally distributed. The design of hybrid operating room, which joins the functions of both open surgery and interventional management together, should be scientific, practical and perspective. (authors)

    Rubber mats offer a possibility to increase lying comfort for sows with positive effects on sow lying behavior and health. However, until now, no information has been reported about the relationship between the softness of rubber mats and the pressure load on certain body areas of sows. We used a total of 68 (40 multiparous, 28 primiparous) German Landrace × German Landrace sows with a BW within the range of 90 to 330 kg (divided in 3 weight classes) to measure peak force and distribution of pressure during lying in the sternal and half recumbent position. Measures were done in an experimental pen that was equipped with a pressure sensor map system (5400 NTL; Tekscan Inc., Boston, MA). Three rubber mats differing in softness (penetration depth: hard mat, 4.0 mm [HM]; soft mat, 14.6 mm [SM]; very soft mat, 43.0 mm [VSM]) were tested and compared to concrete floor (CF) as a reference. Pressure load was analyzed in the sternal position for the sternum, belly, and ham body regions and also in the half recumbent position for the shoulder. For each lying position we determined the body region with the highest pressure load and analyzed the peak force (PF) and the contact area (CA) using a mixed model ANOVA (MIXED procedure of SAS Enterprise, version 4.3., SAS Inst. Inc., Cary, NC) with floor type, weight class of sows, and their interaction as fixed factors. Overall, the highest values for PF in the sternal position were found on the sternum (median: 1.62 N/cm(2)) and in the half recumbent position on the shoulder (median: 2.72 N/cm(2)). In the sternal position PF on the sternum was lower on VSM compared to CF (P = 0.001). In the half-recumbent position PF on the shoulder was lower on VSM compared to CF (P = 0.013) and compared to HM (P = 0.011). The weight of the sows affected PF on the sternum in the sternal position, with lower values in weight class 1 compared to weight class 2 (P = 0.001) and weight class 3 (P = 0.002). Contact area under the sternum was larger on

    2016-05-01

    We describe the case of a 28-year old man with Marfan's syndrome and severe pectus excavatum who required an aortic root replacement for an ascending aortic aneurysm. There was a near-vertical angulation of the sternum that presented challenges with opening and exposure of the heart during aortic surgery. Furthermore, removal of the sternal retractor after aortic repair resulted in sudden loss of cardiac output. A Ravitch procedure was then performed to successfully close the chest without further cardiovascular compromise. We propose that patients with a severe pectus excavatum and mediastinal displacement seen on preoperative CT scanning should be considered for simultaneous, elective repair. PMID:26874148

    Full Text Available During the routine cadaveric dissection, the presence of accessory heads of Sternocleidomastoid was observed on right side. i.e., additional bellies from sternal and clavicle were observed on the right side. These additional slips were innervated by the spinal accessory nerve. These additional slips could have been formed due to unusual splitting in the mesoderm of post-sixth branchial arch during organogenesis. The awareness of variations of sternocleidomastoid muscle is important for Anaesthetists, Plastic surgeons, Orthopaedicians and Dental surgeons while taking muscle flap in reconstructive surgeries and is also important for radiologists while interpreting MR images of this region.

    2009-01-01

    Uncinate processes extend off the vertebral ribs in most species of bird. The processes are a crucial component of ventilatory mechanics, being involved in inspiration and expiration. Here we examine the pattern of ossification of the uncinate processes using histochemistry and biomechanical testing in developing domestic turkeys (Meleagris gallopavo). Ossification begins just before hatching, and the processes are fully ossified in the adult bird. We suggest that the development of these processes is linked to the onset of air breathing and the increase in sternal mass that occurs after hatching.

    A case of Tietze's syndrome is reported. A 43-year-old woman, who had experienced right anterior chest pain and tender swelling of the right first costosternal junction for seven months, showed increased accumulation of the right first, the right fourth, and the left first costochondral junction on bone imaging. Ga-67 imaging showed increased accumulation at the right first costosternal junction. CT showed sclerosis of the sternal manubrium, partial calcification of costal cartilage, and soft tissue swelling. Biopsy of the right first costal cartilage showed chronic inflammation with fibrosis and ossification. Increased uptake of bone gallium imaging is consistent with Tietze's syndrome.15 references.

    @@INTRODUCTION Esophageal hematomas develop from the dissection of the mucosa from the muscular layers of the esophageal wall and represent an uncommon condition affecting all ages[t-3]. Although the most common cause of esophageal hematomas is iatrogenic mechanical injury-induced by prolonged nasogastric intubation, difficult or forceful endoscopic intubation, or the result of variceal injection sclerotherapy- some may be spontaneous,particularly in patients receiving anticoagulants[3-6]. Presenting symptoms most commonly include dysphagia, hematemesis, and sub-sternal or epigastric pain[5,9].

    We describe the case of a 28-year old man with Marfan's syndrome and severe pectus excavatum who required an aortic root replacement for an ascending aortic aneurysm. There was a near-vertical angulation of the sternum that presented challenges with opening and exposure of the heart during aortic surgery. Furthermore, removal of the sternal retractor after aortic repair resulted in sudden loss of cardiac output. A Ravitch procedure was then performed to successfully close the chest without further cardiovascular compromise. We propose that patients with a severe pectus excavatum and mediastinal displacement seen on preoperative CT scanning should be considered for simultaneous, elective repair.

    Surface anatomy and anatomical planes are widely used in education and clinical practice. The planes are largely derived from cadaveric studies and their projections on the skin show discrepancies between and within anatomical reference textbooks. In this study, we reassessed the accuracy of common thoracic and abdominopelvic anatomical planes using computed tomography (CT) imaging in the live adult Turkish population. After patients with distorting pathologies had been excluded, CT images of 150 supine patients at the end tidal inspiration were analyzed. Sternal angle, transpyloric, subcostal, supracristal and pubic crest planes and their relationships to anatomical structures were established by dual consensus. The tracheal bifurcation, azygos vein/superior vena cava (SVC) junction and pulmonary bifurcation were usually below the sternal angle while the concavity of the aortic arch was generally within the plane. The tip of the tenth rib, the superior mesenteric artery and the portal vein were usually within the transpyloric plane while the renal hila and the fundus of the gallbladder were below it. The inferior mesenteric artery was below the subcostal plane and the aortic bifurcation was below the supracristal plane in most adults. Projectional surface anatomy is fundamental to medical education and clinical practice. Modern cross-sectional imaging techniques allow large groups of live patients to be examined. Classic textbook information regarding anatomy needs to be reviewed and updated using the data gathered from these recent studies, taking ethnic differences into consideration.

  4. Trial production of x-ray protective coat in clinico-orthodontics and evaluation of efficiency

    International Nuclear Information System (INIS)

    The authors produced for trial an x-ray protective coat for patients which could be used for any type of dental roentogenography particularly by clinicoorthodontists and could easily exert a sufficient protective effect. The trial product is of coat type covering the front, sides, and back of the trunk and is made of vinyl sheet containing lead and rubber sheet containing lead. When patients put on the coat during cephalography, the internally absorbed dose was decreased greatly in the back corresponding to the 7th cervical vertebra and the area of thyroid and considerably in the area of right joint and the area corresponding to the center of the sternal shaft. The protective effect of the coat was also great in ortho-pantomography in regions corresponding to hemopoietic tissues abundant in bone-marrow, such as the areas of bilateral joints the back corresponding to the 7th cervical vertebra, and the area corresponding to the center of sternal shaft. Internally absorbed doses in different regions due to various types of roentgenography were tabulated. The x-ray protective coat was described to be useful not only in orthodontics but also in roentogenography in the craniocervical region. (Chiba, N.)

  5. Long term results of pectus excavatum in adult women after the nuss procedure

    International Nuclear Information System (INIS)

    Surgical treatment of pectus excavatum in adult women was challenging and the results have not been discussed. In adults with pectus excavatum, asymmetric deformity is common and becomes a critical factor for the repair using the Nuss procedure. Out of 556 surgically treated patients using the Nuss procedure in my own experience, 86 (62: male, 24: female) were more than 18 years old. In order to show cosmetic results of the breast, 10 adult female patients who underwent removal of Pectus bars were included in this study. All cases showed mild to severe asymmetric deformity. In preoperative and post-bar removal CT examinations, a CT slice at the nipple level was selected and measured bilateral chest heights (L/R ratio), sternal twist angle and CT index at this level. Comparison of average chest height L/R ratio (from 1.09 to 1.065), sternal twist angle (from 22.1 deg to 18.40 deg) and CT index (from 0.204 to 0.26) before and after the Nuss procedure showed significant improvement. In conclusion, cosmetic results of the breast in adult women after the Nuss procedure were mostly good. However, asymmetry of the chest wall in the CT examination remained in some cases. Further surgical modification is required for adult patients. (author)

    A 65-year-old woman with a history of breast cancer (stage T2N0M0 treated with left breast conservative therapy 7 years previously followed by hormone therapy) underwent fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (F-18-FDG PET/CT) for restaging due to increased serum tumour markers levels (CA15-3, 37 U/ml and CEA, 8 ng/ml). The patient presented thoracic pain before performing F-18-FDG PET/CT. PET/CT demonstrated an area of increased F-18-FDG uptake corresponding to an osteolytic lesion occupying the upper sternum suspicious for bone metastasis. No other areas of abnormal F-18-FDG uptake were detected in the rest of the body. Based on this PET/CT finding, the patient performed biopsy of the sternal lesion. Histology demonstrated the presence of a sternal plasmacytoma and the patient was addressed to radiation therapy. The role of F-18-FDG PET/CT in patients with multiple myeloma is well known, whereas only some articles evaluated the usefulness of this method in patients with solitary plasmacytomas. In particular, F-18-FDG PET/CT may be useful in demonstrating the evolution of solitary plasmacytomas in multiple myeloma. In our case F-18-FDG PET/CT was useful in detecting a solitary plasmacytoma of the sternum mimicking bone metastasis in a patient with history of breast cancer, correctly addressing to further histological evaluation.

    Full Text Available Osteosarcoma (osteogenic sarcoma: OS is the most common primary malignant bone tumor of long bones, whereas primary osteosarcoma of chest wall, especially in sternum, is extremely rare. We report a 57-year-old man with an immobile slow growing mass located in the middle of the sternum. The patient had no significant pain or tenderness and the past medical history was not remarkable. CT-scan showed a large densely sclerotic sternal mass and MRI revealed an extensive central signal loss within the tumor because of necrosis. We performed a CT-guided needle biopsy, but it was inconclusive. After an incisional biopsy, a high-grade osteosarcoma of the sternum was diagnosed. The patient underwent subtotal sternal resection and reconstruction using synthetic mesh and bone cement followed by chemotherapy and external beam radiotherapy. After one year of follow-up, the patient is back to normal life and is doing the daily activities without problem. By this time, focal recurrence or metastatic disease did not occur.

    Postoperative mediastinitis is defined as an infection of the organs and tissues in the mediastinal space, with an incidence ranging between 0.4% and 5% of cases. This disease severity varies from infection of superficial tissues in the chest wall to fulminant mediastinitis with sternal involvement. Diagnostic criterion for postoperative detection of acute mediastinitis at computed tomography is the presence of fluid collections and gas in the mediastinal space, which might or might not be associated with peristernal abnormalities such as edema of soft tissues, separation of sternal segments with marginal bone resorption, sclerosis and osteomyelitis. Other associated findings include lymphadenomegaly, pulmonary consolidation and pleural/ pericardial effusion. Some of these findings, such as mediastinal gas and small fluid collections can be typically found in the absence of infection, early in the period following thoracic surgery where the effectiveness of computed tomography is limited. After approximately two weeks, computed tomography achieves almost 100% sensitivity and specificity. Patients with clinical suspicion of mediastinitis should be submitted to computed tomography for investigating the presence of fluid collections to identify the extent and nature of the disease. Multidetector computed tomography allows 3D images reconstruction, contributing particularly to the evaluation of the sternum. (author)

    The effects of intravenous administration of variable-dose flumazenil (0, 0.001, 0.005, 0.01, and 0.1 mg/kg) after ketamine (3 mg/kg) and midazolam (0.0 and 0.5 mg/kg) were studied in 18 healthy unmedicated cats from time of administration until full recovery. End-points were chosen to determine whether flumazenil shortened the recovery period and/or modified behaviors previously identified and attributed to midazolam. Overall, flumazenil administration had little effect on recovery or behaviors. One minute after flumazenil administration, all cats were recumbent but a greater proportion of cats which received the highest dose assumed sternal recumbency with head up than any other group. Although not significant, those cats that received the highest flumazenil dose also had shorter mean times for each of the initial recovery stages (lateral recumbency with head up, sternal recumbency with head up and walking with ataxia) than any of the other treatment groups that received midazolam. For complete recovery, flumazenil did decrease the proportion of the cats that was sedated, but did not shorten the time to walking without ataxia. Based on this study, the administration of flumazenil in veterinary practice, at the doses studied, to shorten and/or improve the recovery from ketamine and midazolam in healthy cats cannot be recommended.

    Full Text Available En dos juicios distintos se discutió sobre si las accidentadas llevaban puesto el cinturón de seguridad en el momento del accidente. Las características del accidente y las de las lesiones, junto a la revisión de la bibliografía médica nacional e internacional sobre el asunto llevan a concluir que las fracturas esternales y costales tienen una gran posibilidad de haber sido causadas por el cinturón, especialmente cuando el accidentado no presenta lesiones en el cráneo, en la cara, en el abdomen o en las extremidades superiores. Asimismo, también aumentan con la edad los riesgos de fracturas esternales, costales o ambas.In two different Courts, the lawyers asked if the injured person was using the safety belt when the accident happened. The characteristics of the accident and those of the injuries, along with the review of the national and international medical literature about the question lead to the conclusion that sternal and rib fractures have a great possibility to have been caused by the safety belt itself, specially when the person does not have injuries in the cranium, in the face, in the abdomen or in the arms. On the same way, the risk of sternal and/or costal fractures increases with the age of the person.

    The aim of this study is to report our experience about the treatment of complex sternal and thoracic wounds following cardiothoracic surgery, using vacuum-assisted closure (VAC therapy. Twelve patients presenting with sternal (five cases) and thoracic (seven cases) wounds that were difficult to heal were treated through VAC therapy after the first surgical debridement. The duration of VAC application ranged from 12 to 36 days with an average hospital stay of 24·6 ± 11·4 days. During a mean follow-up of 12 months, we observed complete wound healing in seven cases (58·3%), in an average period of 25·5 ± 14·3 days; one patient died during follow-up, two patients were lost to follow-up and two patients required definitive surgical closure of the wound cavity. In conclusion, VAC therapy promotes faster wound healing, with shorter hospital stay and subsequent lesser in-hospital cost, reducing the mortality rate in the long run. It also promotes early rehabilitation and alleviates the need for a second procedure, thus improving patient satisfaction, with minimal discomfort or inconvenience.

  13. Morphologic assessment of thoracic deformities for the preoperative evaluation of pectus excavatum by magnetic resonance imaging

    International Nuclear Information System (INIS)

    To assess whether MRI is a suitable modality for the preoperative assessment and quantification of pectus excavatum. A total of 69 patients (57 male, 12 female; median age 15 years, range 5-35 years) with pectus excavatum were evaluated preoperatively using standardized MRI sequences on 1.5- and 3-Tesla systems (T2-HASTE/inspiration and expiration, T1-VIBE, T2-TRUFI free-breathing, T2-BLADE). The MR sequences were analysed for quality semiquantitatively. The Haller index, correction index, sternal rotation angle and asymmetry index were assessed; correlations between these indices and changes in inspiration and expiration were evaluated. T2-HASTE was the best sequence to assess pectus excavatum morphology, with a higher quality at 3 T than at 1.5 T. All indices could be assessed in every patient. A total of 37 patients had a symmetric deformity, 32 patients an asymmetric deformity. The Haller index correlated significantly (p < 0.001) with the correction index, both becoming higher in expiration. The asymmetry index correlated with the sternal rotation angle (p < 0.001) and did not change significantly in expiration (p = 0.28). Thoracic MRI is suitable for the preoperative evaluation of patients with pectus excavatum. An exact morphologic assessment is possible without radiation exposure as well as the determination of several indices to quantify the deformities. (orig.)

    Full Text Available Sternal metastasis in thyroid cancer is an uncommon occurrence with only a handful of cases of chest wall resections being done. Sternal reconstruction for both primary and secondary tumors has been performed using various techniques and materials such as the mesh, methyl acrylate resin, and steel plates; however, this is a case of papillary thyroid cancer involving the sternum in a 50-year-old woman who had resection of the sternum with reconstruction using titanium bars and clips (STRATOS system fixed to the clavicles with an underlying Proceed mesh. STRATOS system showed good recovery postoperatively. The functional results were excellent with the patient being able to perform all daily activities unassisted after 1 month and almost complete range of motion with acceptable limitations in power of the shoulder muscles after 2 months. We have reviewed all the English language publications of the subject by doing Medline search for the last 25 years and we present here the surgical management of this pathology with our novel approach by using the titanium steel bars to stabilize both medial aspects of the resected clavicles as a promising therapy for manubrial reconstruction and clavicular fixation.

    The records of 1018 patients with low back pain in a tertiary spine referral practice were reviewed. One hundred thirty-nine out of 1018 (13.6%) underwent technetium-99m planar bone scannings as part of their investigation. Seventy-three out of 139 scans (52%) showed increased uptake in some area, but only 27 out of 139 (19.4%) showed increased uptake specifically in the low back. Scans consistently yielded no findings with reference to the back when the prescan diagnosis was spinal stenosis, lumbar pain syndrome, herniated nucleus pulposus, or postlaminectomy syndrome. Some scans gave positive findings in patients with a diagnosis of degenerative disc disease, pseudoarthrosis, spondylolisthesis, fracture, infection, metabolic disorder, or tumor. Positive scans were generally obtained early after presentation (within 3 months) and negative scans obtained later (after 6 months), suggesting that clinical suspicion is still the main indication for early scanning. Planar bone scanning was helpful in both diagnosis and therapeutic decision-making in many conditions. (orig.)

    Xiaohua Wu

    Full Text Available Germline mutations in the NF1 tumor suppressor gene cause neurofibromatosis type 1 (NF1, a complex genetic disorder with a high predisposition of numerous skeletal dysplasias including short stature, osteoporosis, kyphoscoliosis, and fracture non-union (pseudoarthrosis. We have developed murine models that phenocopy many of the skeletal dysplasias observed in NF1 patients, including reduced bone mass and fracture non-union. We also show that the development of these skeletal manifestations requires an Nf1 haploinsufficient background in addition to nullizygous loss of Nf1 in mesenchymal stem/progenitor cells (MSCs and/or their progenies. This is replicated in two animal models of NF1, PeriCre(+;Nf1(flox/- and Col2.3Cre(+;Nf1(flox/- mice. Adoptive transfer experiments demonstrate a critical role of the Nf1+/- marrow microenvironment in the impaired fracture healing in both models and adoptive transfer of WT bone marrow cells improves fracture healing in these mice. To our knowledge, this is the first demonstration of a non-cell autonomous mechanism in non-malignant NF1 manifestations. Collectively, these data provide evidence of a combinatory effect between nullizygous loss of Nf1 in osteoblast progenitors and haploinsufficiency in hematopoietic cells in the development of non-malignant NF1 manifestations.

    This prospective interventional study carried out at Bangabandhu Sheikh Mujib Medical University and a private hospital in Dhaka, Bangladesh during the period from October 2003 to September 2011. Surgical treatment of degenerative disc disease (DDD) should aim to re-expand the interbody space and stabilize until fusion is complete. The present study conducted to find out the efficacy of using interbody fusion device (Cage) to achieve interbody space re-expansion and fusion in surgical management of DDD. We have performed the interventional study on 53 patients, 42 female and 11 male, with age between 40 to 67 years. All the patients were followed up for 36 to 60 months (average 48 months). Forty seven patients were with spondylolisthesis and 06 with desiccated disc. All subjects were evaluated with regard to immediate and long term complications, radiological fusion and interbody space re-expansion and maintenance. The clinical outcome (pain and disability) was scored by standard pre and postoperative questionnaires. Intrusion, extrusion and migration of the interbody fusion cage were also assessed. Forty seven patients were considered to have satisfactory outcome in at least 36 months follow up. Pseudoarthrosis developed in 04 cases and 06 patients developed complications. In this series posterior lumbar interbody fusion (PLIF) with interbody cage and instrumentation in DDD showed significant fusion rate and maintenance of interbody space. Satisfactory outcome observed in 88.68% cases.

    The neurofibromatosis type 1 (NF1) is characterized by specific cutaneous features (neurofibromas, "café-au-lait" spots of the skin) and alterations of several tissue (nervous, vascular) and bone deformities, such as scoliosis, congenital pseudoarthrosis and bone dysplasia of tibia. Moreover, several studies have shown systemic involvement of bone tissue in NF1 patients, leading to reduced bone mass. The aim of our study was to evaluate some bone mineral metabolism parameters before and after calcium and vitamin D supplementation in NF1 patients. We evaluated in 70 NF1 consecutive patients the mineral metabolism and bone mineral density compared with 40 normal subjects. We showed bone alterations in 35% of patients and the increase of bone formation markers, such as bone isoenzyme of alkaline phosphatase (41.2 ± 15.5 vs. 25.6 ± 8.7 UI; P 60%). Moreover, we revealed a significant reduction of bone mass density at spine (L1-L4) (0.935 ± 0.13 vs. 1.110 ± 0.17 g/cm(2); P mineral bone involvement, with vitamin D deficiency; calcium and vitamin D supplementation is necessary to restore these bone mineral metabolic alterations.

  20. Dyaphiseal open fractures of the forearm follows internal or external fixation

    International Nuclear Information System (INIS)

    The treatment of dyaphiseal open fractures of the forearm follows internal or external fixation. However, the effectivity of both approaches remains controversial. The aim of this descriptive, Wais study, to assess the osteosynthesis by limited approach (internal fixation) as treatment of this type of fractures. Between 1996 and 1999, 22 patients with open dyaphiseal forearm fractures caused by gunshot and treated with this technique were analyzed. The men age was 26.8 years. There were 13 patients with type lllA and 9 patients with type lllB fractures. The mean of comminution was 6.34 mm. Additionally; the mean of quirurgical rinses was 3.7. The complications were: superficial infections, insufficient osteosynthesis and pseudoarthrosis. According to a functional scale the outcomes were, excellent good acceptable and bad. Within parenthesis are the numbers of patients. On the other hand, there were nineteen successful bone consolidations. The observed relative success of the limited approach, with 17 excellent-good cases and 79 bone consolidating, can be explained by the avoiding of unnecessary manipulation of the fractures area which promotes consolidation and reduces infection risk. Moreover the acceptable functional recovery, the absence of complications due to the technique and the restrained use of bone grafts make this technique highly performable

    International Nuclear Information System (INIS)

    In this study 98 patients were evaluated to who are carried out osteosynthesis with plates of under contact in the hospital military of Bogota, between January of 1996 and January of the 2002, with diagnostic of open fractures, fracture closed and pseudoarthrosis that committed the humerus, the cube and the radius, the metacarpal, the femur and the tibia. Of the total, 67,3% corresponded to open fractures and 32,7% they were closed fractures; as for its origin, 54,1% was hurt by firearm, 28,6% for accident rail car and 17,3% for direct trauma. The segment more affected it was the forearm with 43 cases. In the open fractures the cultivation was positive in 11,2%. The average of surgical washed was of 3,2. 110 plates were placed in 98 patients. In 58% one carries out boarding of the fracture focus, and in 41,8% limited boarding. The pursuit average was of 28,2 months. It was not any difference statistically significant between the boarding type and the time of consolidation. It doesn't present osteomyelitis neither septic loosening in the patient's treaties

    Full Text Available In November 2011 a 75-year-old man was admitted to our emergency department with a low back pain caused by a traumatic L1 vertebral collapse with backward projection of posterior wall superior third. The indication for neurosurgical instrumentation was placed, although he refused the treatment. Hence he was treated conservatively without a significant improvement up to January 2012 when, still refusing surgery, he accepted to undergo percutaneous vertebroplasty with a novel bioactive injectable strontium-hydroxyapatite cement. Vertebroplasty was performed without complications. A CT scan, performed the day after the procedure, ruled out extravertebral cement leakage. Pain improvement was significant (preprocedure VAS 10, one-week VAS 4 with a gradual decrease up to three months when it stabilized at 2. CT examination after 1 year showed a good cement osseointegration with osteophytic spurs bridging the superior endplate of the level involved to the inferior one of the level above. The new bone ingrowing property of the strontium-hydroxyapatite containing cement permits to extend the treatment indication also to unstable collapses in which the risk of pseudoarthrosis is very high. In this reported case we evaluated the potential role of percutaneous vertebroplasty in traumatic burst fracture with spinal channel involvement.

    The association of a lumbosacral transitional vertebra with accelerated degeneration of the disc above has been described. Lumbosacral transitional vertebrae have also been reported as a cause of extraforaminal entrapment of the L5 nerve root between the transverse segment of the transitional vertebra and the sacral ala optimally demonstrated by coronal MRI. The association of the lumbosacral transitional vertebra pseudoarthroses and S1 nerve root entrapment due to degenerative stenosis of the nerve root canal has never been described. We present 12 patients with lumbosacral transitional vertebrae that were referred for symptoms and signs of S1 nerve root radiculopathy in which the sagittal and axial MRI sequences failed to identify a plausible cause for the patients' S1 nerve root symptoms. A coronal T1-weighted imaging (T1WI) MRI sequence was consequently added to the investigation. The coronal T1WI MRI sequence demonstrated hypertrophic degenerative stenosis of the S1 nerve root canal at the level of the lumbosacral transitional vertebra pseudoarthrosis, with entrapment of the respective S1 nerve root in all patients. We emphasize the value of coronal T1WI MRI of the lumbosacral junction and sacrum if the cause for S1 radicular symptoms was not identified on conventional sagittal and axial MRI sequences in patients with lumbosacral transitional vertebrae.

    Full Text Available Background: Intravertebral cleft is a structural change in osteoporotic vertebral compression fractures (OVCF, which is the manifestation of ischemic vertebral osteonecrosis complicated with fracture nonunion and pseudoarthrosis and appears in the late stage of OVCF. Despite numerous studies on OVCF, few aim to evaluate the clinicoradiological characteristics and clinical significance of intravertebral cleft in OVCF. This study investigates clinicoradiological characteristics of intravertebral cleft in OVCF and the effect on the efficacy of percutaneous balloon kyphoplasty (PKP. Materials and Methods: PKP was performed on 139 OVCF patients without intravertebral cleft (group A and 44 OVCF patients with intravertebral cleft (group B. The frequency distribution of the affected vertebral body, bone cement infusion volume, imaging manifestation, leakage rate and type, preoperative and postoperative height of the affected vertebral body, visual analog scale (VAS and Oswestry disability index (ODI score were evaluated. Results: Significant differences were found in the frequency distribution of the affected vertebral body and bone cement leakage type between the two groups ( P 0.05 were not detected. In both groups, the postoperative height of the affected vertebral body was significantly improved ( P 0.05. Conclusion: Intravertebral cleft exhibits specific clinical and imaging as well as bone cement formation characteristics. PKP can effectively restore the affected vertebral body height, alleviate pain, and improve daily activity function of patients.

    We are pleased to present this Neurosurgical Focus video supplement on lumbosacral and sacropelvic fixation strategies. Despite advancement in surgical techniques and technologies in spine, achieving consistent solid fusion across the lumbosacral junction remains a major challenge. The anatomy of the lumbosacral junction allows for a higher range of motion compared to other areas of the thoracolumbar spine. The L5-S1 interspace is exposed to significant shear forces. As a result, complications such as pseudoarthrosis, screw pull-out, implant fracture, or sacral fractures can occur. Complications are particularly seen in long fusion constructs ending across the lumbosacral junction. To reduce these complications, various lumbosacral and sacropelvic fixation techniques have been developed and utilized. The current supplement is intended to provide instructional videos that illustrate several current techniques for lumbosacral and sacropelvic fixation. The collection includes techniques for anterior L5-S1 interbody fusion, minimally invasive L5-S1 interbody fusions, lumbosacral pedicle screw placement, sacroiliac fusion, and sacro-alar-iliac screw placement. The authors of the videos in the supplement have provided detailed narration and video illustration to describe the nuances of the various open and minimally invasive techniques for lumbosacral and sacral-pelvic fixation. We are pleased to have such a collection of quality video illustration from experts in the field. It's been our privilege to serve as guest editors for this supplement and we believe that you will enjoy the contents of this supplement. PMID:27364425

    We retrospectively reviewed 161 revision THAs with diaphyseal fitting, mid-modular femoral components performed by ten surgeons at two academic medical centers. The average follow-up was 6.1 years. At final follow-up, 4 patients required re-revision for failure of the femoral component; 3 (2%) for aseptic loosening and 1 for mechanical failure of stem in setting of periprosthetic fracture. There were a total of 24 (14.9%) revisions for any reason, with the most common reason being septic failure (10 of 24). To our knowledge, this is the largest reported series of mid-term survivorship and complications of revision THA with mid-modular femoral components. Our results show that these stems have a low rate of aseptic loosening, subsidence, and mechanical failure.

    Recurrent meningitis is an uncommon life-threatening condition. Here, the case of a 6-year-old boy is reported who had two episodes of meningitis with an IgG3 subclass deficiency. The boy had aseptic meningitis at the age of 3 years, followed by bacterial meningitis at the age of 4 years. Primary immunoglobulin deficiencies are a group of disorders associated with an increased incidence and/or severity of infection. Recurrent infections, sinusitis, bronchitis, and pneumonia are the most frequently observed illnesses in patients with IgG subclass deficiencies, of which an IgG3 subclass deficiency is the most common, especially in adults. Although cases of recurrent viral or bacterial meningitis have been reported, herein a patient is presented with recurrence of aseptic and bacterial meningitis 1 year after the initial episode. Some researchers recommend that all children with episodes of recurrent meningitis should be screened for primary immunoglobulin or complement deficiencies.

    Full Text Available Kikuchi-Fujimoto disease, also known as histiocytic necrotizing lymphadenitis of unknown etiopathogenesis, is a self-limited disease which frequently appears as feverish lymphadenomegaly, thus creating the need for differential diagnosis with lymphoma, systemic lupus erythematosus (SLE, infectious mononucleosis, cat-scratch disease, and toxoplasmosis with lymphonodal impairment. However, there are cases in which it may evolve with complications such as aseptic meningitis, cerebellar ataxia, and aseptic myocarditis. We are presenting a case of a 24-year-old man who had an initial picture of arthralgia, evening fever and adenomegaly. Kikuchi disease was diagnosed through lymph node biopsy with immunohistochemistry and evolves with severe systemic manifestations, such as pericarditis with cardiac tamponade, pneumonitis, hepatitis, and acute kidney failure - the latter has not been reported in literature yet. There was significant improvement of the clinical picture with prednisone

    Calicobenedenia polyprioni n. sp. (Capsalidae) is described from the external surfaces (skin and eye) of wreckfish, Polyprion americanus (Teleostei, Perciformes, Polyprionidae), from the north Atlantic Ocean. The monotypic Calicobenedenia n. gen. is proposed for this species and is characterized, in part, by its members possessing an aseptate haptor armed with 14 submarginal hooks and 1 pair of anchors, a common genital pore opening marginally immediately posterior to the left cephalic lobe, 2 testes juxtaposed near the body midlength, and by lacking cephalic suckers or adhesive discs, accessory haptoral sclerites, and a uterine valve. The new genus most closely resembles Entobdella, which differs from Calicobenedenia by having an aseptate haptor armed with 14 submarginal hooks, 2 pairs of anchors, and a pair of accessary sclerites.

  12. Sequential technetium-99m HMDP-gallium-67 citrate imaging for the evaluation of infection in the painful prosthesis

    International Nuclear Information System (INIS)

    In order to evaluate the clinical utility of sequential technetium-99m HMDP-gallium-67 scanning in patients with painful orthopedic prosthesis, a retrospective review was made of 154 sequential scans performed in 130 patients. Criteria for a positive study included spatially incongruent gallium-technetium uptake or gallium uptake that was congruent but more intense than technetium. Images were interpreted as negative if gallium was congruent and less intense than technetium. Sixty-six patients underwent surgery (31 infected, 35 aseptic), and 64 were evaluated clinically (3 infected, 61 aseptic). The combined results of the surgical and nonsurgical patients yielded a sensitivity of 66%, a specificity of 81%, and an accuracy of 77%. In this series, the technetium-gallium scan combination has proven to be helpful but more recent techniques such as indium-111-labeled leukocytes may prove to be superior to sequential technetium-gallium imaging

    Serum creatine kinase was assessed in 94 consecutive patients without convulsions admitted to hospital due to suspicion of infection of the central nervous system. No reliable discrimination between patients with aseptic and those with bacterial meningitis was obtained. Patients with bacterial...... meningitis and brain oedema, as well as patients with encephalitis, had significantly higher values (P less than 0.01) than patients with meningism, aseptic meningitis and bacterial meningitis without cerebral oedema. Very high values, above 2500 U/1, were encountered in only the most severe cases...... of bacterial meningitis. The highest serum CK value found in patients with encephalitis was 725 U/l. Reference values for control patients with meningism were 16-269 U/1. In a subset of 9 patients creatine kinase isoenzyme analysis was performed. In all cases only muscle type (MM) isoenzyme was found...

    Full Text Available Abstract Introduction Sweet's syndrome is a multi-system inflammatory disorder characterised by painful skin lesions and aseptic neutrophilic infiltration of various organs. We describe a case of Sweet's syndrome with aseptic meningitis in association with Crohn's disease (neuro-Sweet syndrome. This association has never been previously reported. Case presentation A 47-year-old Caucasian male with known Crohn's disease presented with headache, fever and skin lesions resembling erythema nodosum. The cerebrospinal fluid revealed leukocyte pleocytosis and dominant neutrophils, but cultures were negative. A skin biopsy revealed neutrophilic dermatosis compatible with Sweet's disease. The patient made a prompt recovery without the use of corticosteroids. Conclusion Because of its multisystem nature, Sweet's syndrome may present diagnostic difficulty to specialists. Correct diagnosis by skin biopsy will prompt appropriate treatment.

  15. Paraplegia and intracranial hypertension following epidural anesthesia: report of four cases

    1975-09-01

    Full Text Available Four patients who received epidural anesthesia presented sustained myelopathy; three of them had complete paraplegia and one a lumbo-sacral myelopathy with urinary retention. All four patients complained of very intense radicular pains immediately after the analgesic effect of Lidocaine was over. Two patients in whom lumbar puncture was done in the first 24 hours presented an aseptic meningitic reaction in CSF. Paraplegia completed in two to ten months in three patients and in two of them severe intracranial hypertension developped at this time. It is proposed that the disease runs a two-stages course, at least in some cases, characterized by an aseptic meningitis, followed, after a silent period of some months, by signs of adhesive spinal and intracranial arachnoiditis. Intracranial hypertension was controlled by ventriculo-peritoneal shunt; in two patients a transitory effect of intrathecal injections of methyl-prednisolone acetate was observed. Two patients recovered almost completely from paraplegia.

    Magnetic resonance imaging (MRI) was performed on seven patients with aseptic osteonecrosis (n=4) and osteochondritis dissecans (OCD; n=3) of the elbow. Precontrast MRI was superior to plain radiographs, which did not show any abnormality in three cases of osteonecrosis. On gadopentetate-dimeglumine-enhanced T1-weighted images, which were obtained in three patients with osteonecrosis and three patients with OCD, all cases of osteonecrosis demonstrated homogeneous enhancement of the lesions. All cases of OCD were diagnosed on plain radiographs. On MRI one showed significant enhancement of the loose body. In another case an incompletely enhancing loose body was surrounded by a diffusely enhancing region. In the third patient only a small marginal enhancement of the defect was observed. Our results suggest that MRI can improve the accuracy in diagnosis of aseptic osteonecrosis of the elbow. The use of gadopentetate dimeglumine allows the viability of the lesions or the loose bodies to be demonstrated and reparative tissue to be detected. (orig.)

    The goal of this study was to evaluate whether use of an aseptic free-hand approach to ultrasound-guided injection facilitates injection into the thymic gland in mice. We used this interventional radiology technique in young, aged and immunodeficient mice and found that the thymus was visible in all cases. The mean injection period was 8 seconds in young mice and 19 seconds in aged or immunodeficient mice. Injection accuracy was confirmed by intrathymic location of an injected dye or by in vivo bioluminescence imaging of injected luciferase-expressing cells. Accurate intrathymic injection was confirmed in 97% of cases. No major complications were observed. We conclude that an aseptic freehand technique for ultrasound-guided intrathymic injection is safe and accurate and reduces the time required for intrathymic injections. This method facilitates large-scale experiments and injection of individual thymic lobes and is clinically relevant. PMID:25701534
