    To define the outcomes of arthroscopic correction of femoroacetabular impingement (FAI) based on Tönnis findings within a previously reported patient population, including a comparative analysis of Tönnis grade 0 and 1 versus grade 2 changes. Outcomes (modified Harris Hip Score [mHHS]) of a previously published study of arthroscopic correction of FAI were correlated with Tönnis grade. The inclusion criteria were the first 100 consecutive patients undergoing arthroscopic FAI correction with minimum 2-year follow-up. These procedures were performed between December 2003 and May 2006. Grades were determined independently by 2 experienced clinicians. Tönnis grades 0 and 1 were compared with Tönnis grade 2. Independent variables of sex and age were also evaluated. The average age of the entire group was 34.7 years (range, 13-76 years), with 66 male and 34 female patients. Of the patients, 17 had Tönnis grade 0, 49 had Tönnis grade 1, 29 had Tönnis grade 2, and 4 had Tönnis grade 3 (1 unknown). The average mHHS improvement for Tönnis grade 0 was 20.6 points; Tönnis grade 1, 22.2 points; Tönnis grade 2, 14.9 points; and Tönnis grade 3, 18.8 points. The improvement was statistically (P 8 points) significant across all Tönnis grades. There was no difference (P = .077) between Tönnis grades 0 and 1 (21.8 points) versus grade 2 (14.9 points). There was no difference based on sex or age. These data support that statistically and clinically meaningful successful patient-reported outcomes (mHHS) at 2 years can be encountered even in the presence of Tönnis grade 2 radiographic features. Neither age nor sex was an indicator of poorer results within similar Tönnis grades. Level III, case-control study. Copyright © 2018 Arthroscopy Association of North America.

    We detail a modified single incision approach to perform the Tonnis triple pelvic osteotomy by a minimally invasive approach. 12 children underwent minimally invasive Tonnis Osteotomy. There were five boys and seven girls in this study group. Average age was 11 years (9-15 years) at the time of surgery. Mean follow-up was 20.5 months (13-39 months). The average preoperative Antero-Posterior (AP) Centre Edge (CE) angle was -8.8° (-38.6°-18°), the average post-operative AP CE angle was 29.7° (25.1°-43.7°). The average preoperative lateral CE angle was -4.7° (-16°-0°), the average postoperative Lateral CE angle was 28.5° (21.3°-37.4°). The Sharp's angle before and after surgery were 55.7° (51.3°-66°) and 32.4° (16.1°-40.1°) respectively. The mean Tönnis angle before and after the osteotomy were 28.86° (19.7°-43.4°) and 6.3° (0.5°-9.4°) respectively. There was one major complication with sciatic nerve palsy which is in the recovery phase on followup and six minor complications including two cases of transient lateral femoral cutaneous nerve injury, two cases of ischial non-union, over granulation of the wound in one case, and metalwork irritation in one case. We have described a minimally invasive Tonnis osteotomy as a viable option based on our results. This technique is recommended for those who are conversant with the traditional pelvicosteotomies.

CASUÍSTICA E MÉTODO: Foi conduzida uma revisão retrospectiva dos prontuários de 9.322 pacientes submetidos a procedimento cirúrgico no período de janeiro de 1993 a dezembro de 1998. Os dados foram coletados utilizando a opção detalhada do componente de vigilância do paciente cirúrgico do sistema NNIS. Foi calculada a incidência de ISC de acordo com as diferentes categorias individuais dos componentes do índice de risco NNIS (Classe de Ferida, escore ASA e duração da cirurgia. A força da associação entre cada um destes fatores e a ocorrência de ISC foi medida pelo coeficiente Gamma de Goodman-Kruskal (G. RESULTADOS: O escore ASA mostrou-se o melhor preditor de ISC entre os componentes individuais do índice de risco (G=0.49. O índice composto mostrou ser um melhor preditor de ISC do que classe de ferida e teve um poder preditivo semelhante ao do ASA (G=0.50. CONCLUSÕES: O grau de associação entre o índice NNIS e a ocorrência de ISC encontrada no presente estudo está em consonância com os resultados relatados por outros autores e mostrou-se adequado para a avaliação do risco de infecção cirúrgica em nossos pacientes. Amostras utilizando diferentes hospitais com características semelhantes são necessárias para avaliar o risco associado com procedimentos cirúrgicos específicos.

    The objectives were to evaluate a technique, outcome and complications following anterior greater trochanteric with gluteus medius muscle pedicle bone graft (AMG) procedure in the treatment of adolescent and active adult hip disorders. 20 patients (20 hips) with a mean age of 22.7 ± 15.6 (range 10.0-63.5) years who had undergone AMG and been followed up more than 12 months postoperative were retrospectively enrolled in our study. The AMG procedure was performed in conjunction with subcapital osteotomy for slipped capital femoral epiphysis in 12 and open reduction for fracture/dislocation in 8 hips. At the most recent evaluation, patient functional status was rated by the Harris Hip Score (HHS) and radiographic changes were graded according to Tönnis criteria. Complications were defined as Tönnis grade >2 or hip requiring further surgery. Univariate analysis was used to explore factors associated with complications. Spearman's rank correlation coefficient was calculated between HHS and Tönnis grading. At mean follow-up of 4.4 ± 2.6 (range 1.1-9.5) years, mean HHS was 87.4. Tönnis grading was rated as 0 in 10 hips, 1 in 5 hips, 2 in 2 hips, and 3 in 3 hips. Avascular necrosis of the femoral head as a complication developed in 3 hips (15%). Clinical parameters including age at surgery, duration of follow-up and diagnosis were not significantly associated with postoperative complications. A negative correlation between HHS and Tönnis grade was shown by Spearman's rank correlation (rs = -0.49, p = 0.03). The AMG can be safely recommended as an adjunct bone graft procedure when performing anterior open reduction of adolescent and active adult hip disorders.

    Existing radiographic classification schemes (eg, Tönnis criteria) for DDH quantify the severity of disease based on the position of the ossific nucleus relative to Hilgenreiner's and Perkin's lines. By definition, this method requires the presence of an ossification centre, which can be delayed in appearance and eccentric in location within the femoral head. A new radiographic classification system has been developed by the International Hip Dysplasia Institute (IHDI), which uses the mid-point of the proximal femoral metaphysis as a reference landmark, and can therefore be applied to children of all ages. The purpose of this study was to compare the reliability of this new method with that of Tönnis, as the first step in establishing its validity and clinical utility. Twenty standardized anteroposterior pelvic radiographs of children with untreated DDH were selected purposefully to capture the spectrum of age (range, 3 to 32 mo) at presentation and disease severity. Each of the hips was classified separately by the IHDI and Tönnis methods by 6 experienced pediatric orthopaedists from the United States, Canada, Mexico, United Kingdom, and by 2 orthopaedic senior residents. The inter-rater reliability was tested using the Intra Class Correlation coefficient (ICC) to measure concordance between raters. All 40 hips were classifiable by the IHDI method by all raters. Ten of the 40 hips could not be classified by the Tönnis method because of the absence of the ossific nucleus on one or both sides. The ICC (95% confidence interval) for the IHDI method for all raters was 0.90 (0.83-0.95) and 0.95 (0.91-0.98) for the right and left hips, respectively. The corresponding ICCs for the Tönnis method were 0.63 (0.46-0.80) and 0.60 (0.43-0.78), respectively. There was no significant difference between the ICCs of the 6 experts and 2 trainees. The IHDI method of classification has excellent inter-rater reliability, both among experts and novices, and is more widely

    In 1997, a national standardized surveillance system (designated INCLIMECC [Indicadores Clínicos de Mejora Continua de la Calidad]) was established in Spain for health care-associated infection (HAI) in surgery patients, based on the National Nosocomial Infection Surveillance (NNIS) system. In 2005, in its procedure-associated module, the National Healthcare Safety Network (NHSN) inherited the NNIS program for surveillance of HAI in surgery patients and reorganized all surgical procedures. INCLIMECC actively monitors all patients referred to the surgical ward of each participating hospital. We present a summary of the data collected from January 1997 to December 2006 adapted to the new NHSN procedures. Surgical site infection (SSI) rates are provided by operative procedure and NNIS risk index category. Further quality indicators reported are surgical complications, length of stay, antimicrobial prophylaxis, mortality, readmission because of infection or other complication, and revision surgery. Because the ICD-9-CM surgery procedure code is included in each patient's record, we were able to reorganize our database avoiding the loss of extensive information, as has occurred with other systems.

    Because of the persistence and solubility of neonicotinoid insecticides (NNIs), there is concern that these compounds may contaminate sources of drinking water. The objective of this project was to evaluate the distribution of NNIs in raw and treated drinking water from selected municipalities that draw their water from the lower Great Lakes in areas of southern Ontario, Canada where there is high intensity agriculture. Sites were monitored using Polar Organic Chemical Integrative Samplers (POCIS) and by collecting grab samples at six drinking water treatment plants. Thiamethoxam, clothianidin and imidacloprid were detected in both POCIS and grab samples of raw water. The frequency of detection of NNIs was much lower in treated drinking water, but some compounds were still detected at estimated concentrations in the low ng L -1 range. Thiamethoxam was detected in one grab sample of raw drinking water at a mean concentration of 0.28 μg L -1 , which is above the guidelines for drinking water recommended in some jurisdictions, including the European Union directive on pesticide levels water intended for human consumption. Further work is required to determine whether contamination of sources of drinking water with this class of insecticides is a global problem in agricultural regions. Copyright © 2018 Elsevier Ltd.

  6. New arrivals: an indicator for non-indigenous species introductions at different geographical scales

    Directory of Open Access Journals (Sweden)

    Sergej Olenin

    2016-10-01

    Full Text Available Several legal and administrative instruments aimed to reduce the spread of non-indigenous species, that may pose harm to the environment, economy and/or human health, were developed in recent years at international and national levels, such as the International Convention for the Control and Management of Ship’s Ballast Water and Sediments, the International Council for the Exploration of the Sea Code of Practice on the Introductions and Transfers of Marine Organisms, the EU Regulation on Invasive Alien Species and the Marine Strategy Framework Directive, the US Invasive Species Act, the Biosecurity Act of New Zealand, etc. The effectiveness of these instruments can only be measured by successes in the prevention of new introductions. We propose an indicator, the arrival of new non-indigenous species (nNIS, which helps to assess introduction rates, especially in relation to pathways and vectors of introduction, and is aimed to support management. The technical precondition for the calculation of nNIS is the availability of a global, continuously updated and verified source of information on aquatic non-indigenous species. Such a database is needed, because the indicator should be calculated at different geographical scales: 1 for a particular area, such as port or coast of a country within a Large Marine Ecosystem (LME; 2 for a whole LME; and 3 for a larger biogeographical region, including two or more neighboring LMEs. The geographical scale of nNIS helps to distinguish between a primary introduction and secondary spread, which may involve different pathways and vectors. This, in turn, determines the availability of management options, because it is more feasible to prevent a primary introduction than to stop subsequent secondary spread. The definition of environmental target, size of assessment unit and possible limitations of the indicator are also discussed.

    To estimate the frequency of and risk factors for surgical-site infections (SSIs) in Bolivia, and to study the performance of the National Nosocomial Infections Surveillance (NNIS) System risk index in a developing country. A prospective study with patient follow-up until the 30th postoperative day. A general surgical ward of a public hospital in Santa Cruz, Bolivia. Patients admitted to the ward between July 1998 and June 1999 on whom surgical procedures were performed. Follow-up was complete for 91.5% of 376 surgical procedures. The overall SSI rate was 12%. Thirty-four (75.6%) of the 45 SSIs were culture positive. A logistic regression model retained an American Society of Anesthesiologists score of more than 1 (odds ratio [OR], 1.87), a not-clean wound class (OR, 2.28), a procedure duration of more than 1 hour (OR, 1.81), and drain (OR, 1.98) as independent risk factors for SSI. There was no significant association between the NNIS System risk index and SSI rates. However, a "local" risk index constructed with the above cutoff points showed a linear trend with SSI (P < .001) and a relative risk of 3.18 for risk class 3 versus a class of less than 3. SSIs cause considerable morbidity in Santa Cruz. Appropriate nosocomial infection surveillance and control should be introduced. The NNIS System risk index did not discriminate between patients at low and high risk for SSI in this hospital setting, but a risk score based on local cutoff points performed substantially better.

    In this first attempt to implement a standardized surveillance system of surgical site infections (SSI) in a Greek hospital, our objective was to identify areas for improvement by comparing main epidemiologic and microbiologic features of SSI with international data. The National Nosocomial Infections Surveillance (NNIS) system protocols were employed to prospectively collect data for patients in 8 surgical wards who underwent surgery during a 9-month period. SSI rates were benchmarked with international data using standardized infection ratios. Risk factors were evaluated by multivariate logistic regression. A total of 129 SSI was identified in 2420 operations (5.3%), of which 47.3% developed after discharge. SSI rates were higher for 2 of 20 operation categories compared with Spanish and Italian data and for 12 of 20 categories compared with NNIS data. Gram-positive microorganisms accounted for 52.1% of SSI isolates, and Enterococci were predominant. Alarming resistance patterns for Enterococcus faecium and Acinetobacter baumannii were recorded. Potentially modifiable risk factors for SSI included multiple procedures, extended duration of operation, and antibiotic prophylaxis. SSI was associated with prolongation of postoperative stay but not with mortality. Comparisons of surveillance data in our hospital with international benchmarks provided useful information for infection control interventions to reduce the incidence of SSI.

    Abdominal surgical site infections (SSI) cause substantial morbidity and mortality for patients undergoing operative procedures. We determined the incidence of and risk factors for SSI after abdominal surgery in the Department of Abdominal Surgery at the University Clinical Centre of Kosovo (UCCK). Prospective surveillance of patients undergoing abdominal surgery was performed between December 2005 and June 2006. CDC definitions were followed to detect SSI and study forms were based on Europe Link for Infection Control through Surveillance (HELICS) protocol. A total of 253 surgical interventions in 225 patients were evaluated. The median age of patients was 42 years and 55.1% of them were male. The overall incidence rate of SSI was 12%. Follow-up was achieved for 84.1% of the procedures. For patients with an SSI, the median duration of hospitalization was 9 days compared with 4 days for those without an SSI (p 2, use of antibiotic prophylaxis and NNIS class of > 2 were all significant at p < .001. The SSI rates for the NNIS System risk classes 0, 1 and 2-3 were 4.2%, 46.7% and 100%, respectively. SSI caused considerable morbidity among surgical patients in UCCK. Appropriate active surveillance and infection control measures should be introduced during preoperative, intra-operative, and postoperative care to reduce infection rates.

    The Indicadores Clínicos de Mejora Continua de la Calidad (INCLIMECC) program was established in Spain in 1997. INCLIMECC is a prospective system of health care-associated infection (HAI) surveillance that collects incidence data in surgical and intensive care unit patients. The protocol is based on the National Healthcare Safety Network (NHSN) surveillance system, formerly known as the National Nosocomial Infection Surveillance (NNIS) system, and uses standard infection definitions from the US Centers for Disease Control and Prevention. Each hospital takes part voluntarily and selects the units and surgical procedures to be surveyed. This report is a summary of the data collected between January 1997 and June 2012. A total of 370,015 patients were included, and the overall incidence of surgical wound infection (SWI) was 4.51%. SWI rates are provided by NHSN operating procedure category and NNIS risk index category. More than 27% of the patients received inadequate antibiotic prophylaxis, the main reason being unsuitable duration (57.05% of cases). Today, the INCLIMECC network includes 64 Spanish hospitals. We believe that an HAI surveillance system with trained personnel external to the surveyed unit is a key component not only in infection control and prevention, but also in a quality improvement system.

    We have developed an original system to conduct surgical site infection (SSI) surveillance. This system accumulates SSI surveillance information based on the National Nosocomial Infections Surveillance (NNIS) System and the Japanese Nosocomial Infections Surveillance (JNIS) System. The features of this system are as follows: easy input of data, high generality, data accuracy, SSI rate by operative procedure and risk index category (RIC) can be promptly calculated and compared with the current NNIS SSI rate, and the SSI rates and accumulated data can be exported electronically. Using this system, we monitored 798 patients in 24 operative procedure categories in the Digestive Organs Surgery Department of Mazda Hospital, Mazda Motor Corporation, from January 2004 through December 2005. The total number and rate of SSI were 47 and 5.89%, respectively. The SSI rates of 777 patients were calculated based on 15 operative procedure categories and Risk Index Categories (RIC). The highest SSI rate was observed in the rectum surgery of RIC 1 (30%), followed by the colon surgery of RIC3 (28.57%). About 30% of the isolated infecting bacteria were Enterococcus faecalis, Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Escherichia coli. Using quantification theory type 2, the American Society of Anesthesiology score (4.531), volume of hemorrhage under operation (3.075), wound classification (1.76), operation time (1.352), and history of diabetes (0.989) increased to higher ranks as factors for SSI. Therefore, we evaluated this system as a useful tool in safety control for operative procedures.

    The technique of hip arthroscopic surgery is advancing and becoming more commonly performed. However, most current reported results are limited to short-term follow-up, and therefore, the durability of the procedure is largely unknown. To perform a multicenter analysis of mid-term clinical outcomes of arthroscopic hip labral repair and determine the risk factors for patient outcomes. Cohort study; Level of evidence, 3. Prospectively collected data of primary hip arthroscopic labral repair performed at 4 high-volume centers between 2008 and 2011 were reviewed retrospectively. Patients were assessed preoperatively and postoperatively with the visual analog scale (VAS), modified Harris Hip Score (mHHS), and Hip Outcome Score-Sports-Specific Subscale (HOS-SSS) at a minimum of 5 years' follow-up. Factors including age, body mass index (BMI), Tönnis grade, and cartilage grade were analyzed in relation to outcome scores, and revision rates were determined. Failure was defined as subsequent ipsilateral hip surgery, including revision arthroscopic surgery and open hip surgery. A total of 303 patients (101 male, 202 female) with a mean age of 32.0 years (range, 10.7-58.9 years) were followed for a mean of 5.7 years (range, 5.0-7.9 years). Patients achieved mean improvements in VAS of 3.5 points, mHHS of 20.1 points, and HOS-SSS of 29.3 points. Thirty-seven patients (12.2%) underwent revision arthroscopic surgery, and 12 (4.0%) underwent periacetabular osteotomy, resurfacing, or total hip arthroplasty during the study period. Patients with a BMI >30 kg/m 2 had a mean mHHS score 9.5 points lower and a mean HOS-SSS score 15.9 points lower than those with a BMI ≤30 kg/m 2 ( P 35 years at surgery had a mean mHHS score 4.5 points lower and a HOS-SSS score 6.7 points lower than those aged ≤35 years ( P = .03). Patients with Tönnis grade 2 radiographs demonstrated a 12.5-point worse mHHS score ( P = .02) and a 23.0-point worse HOS-SSS score ( P SSS scores after arthroscopic

    BACKGROUND: Adductor-related groin pain and bony morphology such as femoroacetabular impingement (FAI) or hip dysplasia can coexist clinically. A previous randomised controlled trial in which athletes with adductor-related groin pain underwent either passive treatment (PT) or active treatment (AT......) showed good results in the AT group. The primary purpose of the present study was to evaluate if radiological signs of FAI or hip dysplasia seem to affect the clinical outcome, initially and at 8-12 years of follow-up. METHODS: 47 patients (80%) were available for follow-up. The clinical result......, there was no significant difference in the distribution of Tönnis grades between hips that had an unchanged or improved outcome compared with hips that had a worse outcome over time (p=0.145). CONCLUSIONS: No evidence was found that bony hip morphology related to FAI or dysplasia prevents successful outcome...

    BACKGROUND AND PURPOSE: An acetabular labral tear is a diagnostic challenge. Various clinical tests have been described, but little is known about their diagnostic sensitivity and specificity. We investigated the diagnostic validity of clinical tests and ultrasound as compared with MR arthrography...... no or only slight signs of osteoarthritis (Tönnis grade 0-1). RESULTS: MR arthrography identified labral tears in 17 of the 18 hips. Ultrasound had a sensitivity of 94%, a positive predictive value of 94%, and was false negative in only 1 case compared to MR arthrography. The impingement test had the best...... diagnostic ability of the clinical tests, with a sensitivity of 59% and a specificity of 100%. The positive predictive value was 100% while the negative predictive value was 13%. INTERPRETATION: The impingement test is helpful in identifying acetabular labral tears. If this test is negative and if a labral...

    Full Text Available Slipped capital femoral epiphysis (SFCE may lead to femoro acetabular impingement and long-term function impairment, depending on initial displacement and treatment. There are several therapeutic options which include in situ fixation (ISF. The objective of this study was to evaluate long-term functional and radiographic outcomes of patients with SFCE treated with ISF. We conducted a single-center, retrospective study evaluating the clinical and radiographic outcomes of SCFE in situ fixation with a mean follow-up of 26 years (10- 47. Analysis of preoperative and last follow up radiographs was performed. The functional status of the hip was evaluated according to the Oxford hip score-12 and the radiographic osteoarthritis stage was rated according to Tönnis classification. Signs of femoro acetabular impingement were sought. Ten patients (11 hips were included. The average initial slip was 33.5° (10-62. At final follow up, the average Oxford hip score was 19.3 (12-37, it was good for groups who had a small initial slip (16.7 or moderate (17 and fair for the severe group (27. Average Tönnis grade was 1.3 (0- 3. The average alpha angle was 65.3° (50- 80°. Femoro acetabular impingement was likely in 100% of patients with severe slip, in 50% of patients with moderate slip and in 33% of patients with a slight slip. In situ fixation generated poor functional results, substantial hip osteoarthritis and potential femoro acetabular impingement in moderate to severe SCFE’s. However, in cases with minor displacement, functional and radiographic results are satisfactory. The cut off seems to be around 30° slip angle, above which other treatment options should be considered.

    Effective and comparable surveillance for central venous catheter-related bloodstream infections (CLABSIs) in the intensive care unit requires a reproducible case definition that can be readily applied by infection control professionals. Using a questionnaire containing clinical cases, reproducibility of the National Nosocomial Infection Surveillance System (NNIS) surveillance definition for CLABSI was assessed in an Australian cohort of infection control professionals participating in the Victorian Hospital Acquired Infection Surveillance System (VICNISS). The same questionnaire was then used to evaluate the reproducibility of the National Healthcare Safety Network (NHSN) surveillance definition for CLABSI. Target hospitals were defined as large metropolitan (1A) or other large hospitals (non-1A), according to the Victorian Department of Human Services. Questionnaire responses of Centers for Disease Control and Prevention NHSN surveillance experts were used as gold standard comparator. Eighteen of 21 eligible VICNISS centers participated in the survey. Overall concordance with the gold standard was 57.1%, and agreement was highest for 1A hospitals (60.6%). The proportion of congruently classified cases varied according to NNIS criteria: criterion 1 (recognized pathogen), 52.8%; criterion 2a (skin contaminant in 2 or more blood cultures), 83.3%; criterion 2b (skin contaminant in 1 blood culture and appropriate antimicrobial therapy instituted), 58.3%; non-CLABSI cases, 51.4%. When survey questions regarding identification of cases of CLABSI criterion 2b were removed (consistent with the current NHSN definition), overall percentage concordance increased to 62.5% (72.2% for 1A centers). Further educational interventions are required to improve the discrimination of primary and secondary causes of bloodstream infection in Victorian intensive care units. Although reproducibility of the CLABSI case definition is relatively poor, adoption of the revised NHSN definition

    To describe the rate, risk factors, and outcome of ventilator-associated pneumonia (VAP) in pediatric patients. This prospective surveillance study of VAP among all patients receiving mechanical ventilation for 48 hours or more admitted to a pediatric intensive care unit (PICU) in Saudi Arabia from May 2000 to November 2002 used National Nosocomial Infections Surveillance (NNIS) System definitions. Three hundred sixty-one eligible patients were enrolled. Most were Saudi with a mean age of 28.6 months. Thirty-seven developed VAP. The mean VAP rate was 8.87 per 1,000 ventilation-days with a ventilation utilization rate of 47%. The mean duration of mechanical ventilation was 21 days for VAP patients and 10 days for non-VAP patients. The mean PICU stay was 34 days for VAP patients and 15 days for non-VAP patients. Among VAP patients, Pseudomonas aeruginosa was the most common organism, followed by Staphylococcus aureus. Other gram-negative organisms were also encountered. There was no significant difference between VAP and non-VAP patients regarding mortality rate. Witnessed aspiration, reintubation, prior antibiotic therapy, continuous enteral feeding, and bronchoscopy were associated with VAP. On multiple logistic regression analysis, only prior antibiotic therapy, continuous enteral feeding, and bronchoscopy were independent predictors of VAP. The mean VAP rate in this hospital was higher than that reported by NNIS System surveillance of PICUs. This study has established a benchmark for future studies of VAP in the pediatric intensive care population in Saudi Arabia. Additional studies from the region are necessary for comparison and development of preventive measures.

    A characteristic of polyglutamine diseases is the increased propensity of disease proteins to aggregate, which is thought to be a major contributing factor to the underlying neurodegeneration. Healthy cells contain mechanisms for handling protein damage, the protein quality control, which must be impaired or inefficient to permit proteotoxicity under pathological conditions. We used a quantitative analysis of immunohistochemistry of the pons of eight patients with the polyglutamine disorder spinocerebellar ataxia type 3. We employed the anti-polyglutamine antibody 1C2, antibodies against p62 that is involved in delivering ubiquitinated protein aggregates to autophagosomes, antibodies against the chaperones HSPA1A and DNAJB1 and the proteasomal stress marker UBB⁺¹. The 1C2 antibody stained neuronal nuclear inclusions (NNIs), diffuse nuclear staining (DNS), granular cytoplasmic staining (GCS) and combinations, with reproducible distribution. P62 always co-localized with 1C2 in NNI. DNS and GCS co-stained with a lower frequency. UBB⁺¹ was present in a subset of neurones with NNI. A subset of UBB⁺¹-containing neurones displayed increased levels of HSPA1A, while DNAJB1 was sequestered into the NNI. Based on our results, we propose a model for the aggregation-associated pathology of spinocerebellar ataxia type 3: GCS and DNS aggregation likely represents early stages of pathology, which progresses towards formation of p62-positive NNI. A fraction of NNI exhibits UBB⁺¹ staining, implying proteasomal overload at a later stage. Subsequently, the stress-inducible HSPA1A is elevated while DNAJB1 is recruited into NNIs. This indicates that the stress response is only induced late when all endogenous protein quality control systems have failed. © 2011 The Authors.

    Developmental hip dysplasia is a frequent cause of coxofemoral pain in young adults. Bernese periacetabular osteotomy emerges as a possible option for the management of pain relief and functional limitation, in order to delay the need for arthroplasty in these patients. A descriptive-retrospective study was conducted on 26 selected patients with symptomatic developmental hip dysplasia treated with bernese periacetabular osteotomy between 1996 and 2009 (94% women). Mean age at time of surgery was 39.8 y (15-49 y), with a mean follow-up of 10 years. Osteoarthritis (OA Tönnis scale), acetabular index and Wiberg angle were evaluated by radiology and functionality was valued by using the de Merle-D'Aubigné-Postel scale. The mean hospitalization time was 10 days. At 10 years, the mean radiography value of acetabular index was 9.03° and 38.3° for Wiberg angle (17° and 27° correction, respectively, above the mean pre-operative values). Joint lock was referred to by 43% of patients, and 53% to non-evidence based limb failure. Mean functional value was 14.30 (Good). At 5 years of follow-up, 20% advanced at least by one grade in OA Tönnis scale compared to their pre-operative status, increasing to 55% at 10 years. At 10 years after surgery, 83% patients did not need arthroplasty and 85% showed high satisfaction level. Bernese periacetabular osteotomy is a useful alternative in young adults with symptomatic developmental hip dysplasia that can improve pain relief, femoral head coverage, and slow down coxofemoral osteoarthrosis progression in order to delay arthroplasty.

    To investigate the feasibility of using artificial neural networks to estimate stiffness from MR elastography (MRE) data. Artificial neural networks were fit using model-based training patterns to estimate stiffness from images of displacement using a patch size of ∼1 cm in each dimension. These neural network inversions (NNIs) were then evaluated in a set of simulation experiments designed to investigate the effects of wave interference and noise on NNI accuracy. NNI was also tested in vivo, comparing NNI results against currently used methods. In 4 simulation experiments, NNI performed as well or better than direct inversion (DI) for predicting the known stiffness of the data. Summary NNI results were also shown to be significantly correlated with DI results in the liver (R 2  = 0.974) and in the brain (R 2  = 0.915), and also correlated with established biological effects including fibrosis stage in the liver and age in the brain. Finally, repeatability error was lower in the brain using NNI compared to DI, and voxel-wise modeling using NNI stiffness maps detected larger effects than using DI maps with similar levels of smoothing. Artificial neural networks represent a new approach to inversion of MRE data. Summary results from NNI and DI are highly correlated and both are capable of detecting biologically relevant signals. Preliminary evidence suggests that NNI stiffness estimates may be more resistant to noise than an algebraic DI approach. Taken together, these results merit future investigation into NNIs to improve the estimation of stiffness in small regions.

    Full Text Available Abstract Background Surgical site infections (SSI remain a major clinical problem in terms of morbidity, mortality, and hospital costs. Nearly 60% of SSI diagnosis occur in the postdischarge period. However, literature provides little information on risk factors associated to in-hospital and postdischarge SSI occurrence. A national prospective multicenter study was conducted with the aim of assessing the incidence of both in-hospital and postdisharge SSI, and the associated risk factors. Methods In 2002, a one-month, prospective national multicenter surveillance study was conducted in General and Gynecological units of 48 Italian hospitals. Case ascertainment of SSI was carried out using standardized surveillance methodology. To assess potential risk factors for SSI we used a conditional logistic regression model. We also reported the odds ratios of in-hospital and postdischarge SSI. Results SSI occurred in 241 (5.2% of 4,665 patients, of which 148 (61.4% during in-hospital, and 93 (38.6% during postdischarge period. Of 93 postdischarge SSI, sixty-two (66.7% and 31 (33.3% were detected through telephone interview and questionnaire survey, respectively. Higher SSI incidence rates were observed in colon surgery (18.9%, gastric surgery (13.6%, and appendectomy (8.6%. If considering risk factors for SSI, at multivariate analysis we found that emergency interventions, NNIS risk score, pre-operative hospital stay, and use of drains were significantly associated with SSI occurrence. Moreover, risk factors for total SSI were also associated to in-hospital SSI. Additionally, only NNIS, pre-operative hospital stay, use of drains, and antibiotic prophylaxis were associated with postdischarge SSI. Conclusion Our study provided information on risk factors for SSI in a large population in general surgery setting in Italy. Standardized postdischarge surveillance detected 38.6% of all SSI. We also compared risk factors for in-hospital and postdischarge SSI

    Full Text Available BACKGROUND CDC defines surgical site infection as ‘Infections related to operative procedure that occurs at or near surgical incision within 30 days of operative procedure or within one year if the implant is left in situ’. Surgical site infection (SSI is 3 rd most frequently reported nosocomial infection (12%-16% as per National Nosocomial Infection Surveillance (NNIS. The aim of this study was to investigate the antimicrobial susceptibility pattern of organisms causing SSI. MATERIALS AND METHODS During a two year study period in a tertiary care hospital, 19,127 patients underwent surgeries in various surgical departments. Of these 517 (2.7% developed surgical site infection. The surgical wounds were classified by CDC & NNIS criteria into 4 classes. Two wound swabs were taken and processed by standard microbiological techniques. Antimicrobial susceptibility along with testing of ESBLs, MBLs, AmpCβ lactamases was done for all isolates causing SSI. RESULTS Among 19,127 patients, 517 (2.7% developed SSI. It was highest in patients of perforation peritonitis (11.99%.Among 517 specimens, 340 (65.76% showed growth and 177 (34.23% were culture negative.

    The third most common healthcare-associated infection is surgical site infection (SSI), accounting for 14%-16% of infections. These SSIs are associated with high morbidity, numerous deaths, and greater cost. A prospective study was conducted to assess the incidence of SSI in a single university hospital in Croatia. We used the Hospital in Europe Link for Infection Control through Surveillance (HELICS) protocol for surveillance. The SSIs were classified using the standard definition of the National Nosocomial Infections Surveillance (NNIS) system. The overall incidence of SSI was 1.44%. The incidence of infection in the open cholecystectomy group was 6.06%, whereas in the laparoscopic group, it was only 0.60%. The incidence density of in-hospital SSIs per 1,000 post-operative days was 5.76. Patients who underwent a laparoscopic cholecystectomy were significantly younger (53.65±14.65 vs. 64.42±14.17 years; pconcept for the monitoring of SSI, but in the case of cholecystectomy, additional factors such as antibiotic appropriateness, gallbladder entry, empyema of the gallbladder, and obstructive jaundice must be considered.

    To investigate the outcomes of an anteverting triple periacetabular osteotomy for the treatment of hip instability in skeletally immature patients with Down syndrome. We evaluated 16 patients (21 hips) with Down syndrome and hip instability who underwent an anteverting triple periacetabular osteotomy between 2007 and 2016. There were nine females and seven males with an average age of 7.4 years SD 2.0. We assessed the level of hip pain, gait ability and clinical stability at a minimum of one year after surgery. Radiographic evaluation included pre- and postoperative lateral centre-edge angle (LCEA), Tönnis acetabular angle and extrusion index. After an average follow-up of 4.1 years SD 2.6, 20 of 21 hips (95%) remained clinically stable. In all, 12 of 16 (75%) patients had a full gait without a major limp, but three patients (19%) had a persistent limp. Of the 21 procedures, one hip (5%) was considered a failure due to persistent instability. There was a mean increase of 18.3º SD 15.3º of the LCEA (p treatment of an infection; which was considered a major complication. The anteverting triple periacetabular osteotomy provided global deformity correction and achieved hip stability in 95% of the hips after a mean follow-up of 4.1 years. Therapeutic level IV.

    Full Text Available Background: The prevalence of neglected developmental dysplasia of the hip (DDH has been decreasing. Nowadays, the disease is rarely seen in walking age children. The purpose of this study is to assess the results of simultaneous osteotomy of femur and pelvic bones in such children. Method: We performed a retrospective study on 30 children aged 3.8±0.9 (range: 1.5-7 years old, with DDH who underwent surgical operation in our hospital from August 2001 to September 2006. Tönnis and Severin grading systems were used to classify the radiographic status of the hip in pre- and postoperative era, respectively. Improvement in function and limp was also evaluated by the modified McKay’s classification. Results: From the 30 cases, six patients excluded in the course of the study and among the remaining patients, 12 had bilateral involvement. The mean follow-up period was 7.6±0.8 (range: 5.1-11.3 years. During the last visit, radiographic status of the operated joints, according to Severin classification was as follows: Class I: 12 patients; Class II: 20 patients; Class III: 3 patients; Class IV: 1 patient; and Class VI: 1 patient. Conclusion: Although through the follow-up, two hips subluxated, necrosis happened in three and one joint was re-dislocated, simultaneous femoral and innominate osteotomy in the walking age children with DDH has relatively good clinical outcomes.

    Surveillance of surgical site infections (SSI) is a priority. One of the fundamental principles for the surveillance of SSI is based on receiving effective field feedback (retro-information). The aim of this study was to report the results of a program of SSI surveillance and validate the hypothesis that there is a correlation between creating a SSI surveillance program and a reduction in SSI. The protocol was based on the weekly collection of surveillance data obtained directly from the different information systems in different departments. A delay of 3 months was established before extraction and analysis of data and information from the surgical teams. The NNIS index (National Nosocomial Infections Surveillance System) developed by the American surveillance system and the reduction of length of hospital stay index Journées d'hospitalisation évitées (JHE). Since the end of 2009, 7156 surgical procedures were evaluated (rate of inclusion 97.3%), and 84 SSI were registered with a significant decrease over time from 1.86% to 0.66%. A total of 418 days of hospitalization have been saved since the beginning of the surveillance system. Our surveillance system has three strong points: follow-up is continuous, specifically adapted to orthopedic traumatology and nearly exhaustive. The extraction of data directly from hospital information systems effectively improves the collection of data on surgical procedures. The implementation of a SSI surveillance protocol reduces SSI.

    Full text: Many nuclear institutions in the world, especially the developing countries, are heavily dependent on the financing provided by the government for their activities. In August 2000, Malaysia in cooperation with the International Atomic Energy Agency (IAEA), organized a Regional Seminar on Strategies and Approaches towards Self-reliance and Sustainability of National Nuclear Institutions (NNIs). As a result of the forum and deliberation of the seminar, there is now a greater awareness among the member states that there should be a paradigm shift in the thinking of policy and decision makers. The main challenges and limitations faced by these policy and decision makers are firstly, in order that nuclear institutions to stay relevant in the context of mainstream socio-economic development, the NNIs must generate revenue to achieve self-reliance and sustainability. Secondly, the need for the NNIs to fulfil social obligations, i.e., provision of reasonably good and low cost technology to support food and agriculture production; health care system; safe industrial development and clean environment. Thirdly, to improve the image and acceptance of nuclear technology by the consumers and public in the face of proliferation of nuclear-arms race. Malaysia has been successful in addressing these conflicting requirements and challenges, i.e. generating revenue for sustainability and at the same time providing services and consultancy at a reasonable rate. The Malaysian Institute for Nuclear Technology Research (MINT) is now 30% sustainable in terms of operational costs via provision of services and consultancies to both private and government agencies. Technical services are provided in the areas of Industrial Technology (e.g. ND evaluation); Radiation Processing Services (e.g., medical product sterilization and food and herbal irradiation, and cross-linking of wire and cables); Dosimetry Services for personal and radiation equipment (e.g. personal dosimetry

    Full Text Available Aims: Nosocomial infection is associated with increased mortality, morbidity, and length of stay. Detection of infection, identify the etiology of bacterial antibiotic resistance pattern, is necessary given the widespread use of antibiotics and antibiotic-resistant organisms. Materials and Methods: This cross-sectional study was done on 288 patients admitted to the Beheshti Hospitals in Kashan based on NNIS definitions according to the state of Health and Medical education. In this study infections and antibiotic resistance symptoms were found. Data analyses were performed with Chi-square test. Results: Among the 288 patients studied, with mean out of hospital infection was 0.80%. Most cases of infection associated were pneumonia. The highest rates of infection were in the Intensive Care Unit (ICU with 51.7%. Nosocomial infection in ICU wards was associated with increased mortality and morbidity. The most common types were ventilator-associated pneumonia. Among the microorganisms, negative Gram was seen more. The common pathogens were including Acinetobacter, Escherichia coli, and Klebsiella. Antimicrobial resistance was generally increasing and had emerged from selective pressure from antibiotic use and transmission through health staff. Conclusion: This study showed a correlation between antibiotic use and resistance of microorganisms is significant. Hence, it seems that reducing aggressive acts and conduct hygiene education and monitoring act of antibiotics is necessary to prevent antibiotic resistance.

    Hand hygiene is a fundamental measure for the control of nosocomial infection. However, sustained compliance with hand hygiene in health care workers is poor. We attempted to enhance compliance with hand hygiene by implementing education, training, and performance feedback. We measured nosocomial infections in parallel. We monitored the overall compliance with hand hygiene during routine patient care in intensive care units (ICUs); 1 medical surgical ICU and 1 coronary ICU, of 1 hospital in Buenos Aires, Argentina, before and during implementation of a hand hygiene education, training, and performance feedback program. Observational surveys were done twice a week from September 2000 to May 2002. Nosocomial infections in the ICUs were identified using the National Nosocomial Infections Surveillance (NNIS) criteria, with prospective surveillance. We observed 4347 opportunities for hand hygiene in both ICUs. Compliance improved progressively (handwashing adherence, 23.1% (268/1160) to 64.5% (2056/3187) (RR, 2.79; 95% CI: 2.46-3.17; P nosocomial infection in both ICUs decreased from 47.55 per 1000 patient-days (104/2187) to 27.93 per 1000 patient days (207/7409) RR, 0.59; 95% CI: 0.46-0.74, P hand hygiene, coinciding with a reduction in nosocomial infection rates in the ICUs.

    A retroauricular approach is routinely used for treating chronic otitis media. The incidence of surgical site infections after ear surgery is around 10% in contaminated or dirty procedures. This observational prospective study describes surgical site infections after chronic otitis media surgery with the retroauricular approach and investigated their potential predictive factors. This observational prospective study included patients suffering from chronic otitis media and eligible for therapeutic surgery with a retroauricular approach. During follow-up, surgical site infections were defined as "early" if occurring within 30 days after surgery or as "late" if occurring thereafter. The data of 102 patients were analysed. Concerning early surgical site infections, four cases were diagnosed (3.9%) and a significant association was found with preoperative antibiotic therapy, wet ear at pre-operative examination, class III (contaminated) in the surgical wound classification, NNIS (National Nosocomial Infection Surveillance) index > 1, and oral post-operative antibiotic use. Seven late surgical site infections were diagnosed (7.1%) between 90 and 160 days after surgery and were significantly correlated to otorrhoea during the 6 months before surgery, surgery duration ≤60 minutes, canal wall down technique and use of fibrin glue. Surgical site infections after chronic otitis media surgery seem to be associated with factors related to the inflammatory state of the middle ear at the time of surgery in early infections and with chronic inflammation in late infections. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

    Full Text Available Abstract Background This study aimed to determine the occurrence of nosocomial infections (NIs, including infection rates, main infection sites, and common microorganisms. Patients included in the study were taken from a newborn intensive care unit (NICU, in a hospital in South Korea. Methods A retrospective cohort study was performed by reviewing chart. The subjects were 489 neonates who were admitted to the NICU, survived longer than 72 hours, and not transferred to another unit, between Jan. 1. 1995 to Sep. 30, 1999. NIs were identified according to the NNIS definition. Data were analyzed with descriptive statistics. Results Cumulative incidence rate for NIs was 30.3 neonates out of 100 admissions, with a total of 44.6 infections. The incidence density was average 10.2 neonates and 15.1 infections per 1000 patient days. The most common infections were pneumonia (28%, bloodstream infection (26%, and conjunctivitis (22%. Major pathogens were Gram-positives such as Staphylococcus aureus and coagulase-negative staphylococci. The factors associated with NI was less than 1500 g of birth weight, less than 32 weeks of gestational age, and less than 8 of apgar score. There's no statistical difference in discharge status between two groups, but hospital stay was longer in subjects with nosocomial infection than those without infection. Conclusion Although the distribution of pathogens was similar to previous reports, a high rate of nosocomial infection and in particular conjunctivitis was observed in this study that merits further evaluation.

    The impact of surgical wound infection on public health justifies its surveillance and prevention. Our objectives were to estimate the incidence of surgical wound infection in breast procedures and assess its protocol of antibiotic prophylaxis and preoperative preparation. Observational multicentre prospective cohort study of incidence of surgical wound infection. Incidence was evaluated, stratified by National Nosocomial Infection Surveillance (NNIS) risk index and we calculated the standardized incidence ratio (SIR). The SIR was compared with Spanish rates and U.S. rates. The compliance and performance of the antibiotic prophylaxis and preoperative preparation protocol were assessed and their influence in the incidence of infection with the relative risk. Ten hospitals from the Comunidad de Madrid were included, providing 592 procedures. The cumulative incidence of surgical wound infection was 3.89% (95% CI: 2.3-5.5). The SIR was 1.82 on the Spanish rate and 2.16 on the American. Antibiotic prophylaxis was applied in 97.81% of cases, when indicated. The overall performance of antibiotic prophylaxis was 75%, and 53% for preoperative preparation. No association was found between infection and performance of prophylaxis or preoperative preparation (P>.05). Our incidence is within those seen in the literature although it is somewhat higher than the national surveillance programs. The performance of prophylaxis antibiotic must be improved, as well as the recording of preoperative preparation data. Copyright © 2010 Elsevier España, S.L. All rights reserved.

Since 1987, the authors have been performing concurrent surveillance of surgical patients and confidentially reporting surgeon-specific ssi rates to individual surgeons and their clinical directors, and providing surgeons with the mean rates of their peers. The program has been gradually refined and expanded. Data are now collected on wound infection risk and report risk adjusted rates compared with the mean for hospitals in the United States National Nosocomial Infections Surveillance (nnis data bank.

    To report on intra-observer, inter-observer, and inter-method reliability and agreement for radiological measurements used in the diagnosis of hip dysplasia at skeletal maturity, as obtained by a manual and a digital measurement technique. Pelvic radiographs from 95 participants (56 females) in a follow-up hip study of 18- to 19-year-old patients were included. Eleven radiological measurements relevant for hip dysplasia (Sharp's, Wiberg's, and Ogata's angles; acetabular roof angle of Tönnis; articulo-trochanteric distance; acetabular depth-width ratio; femoral head extrusion index; maximum teardrop width; and the joint space width in three different locations) were validated. Three observers measured the radiographs using both a digital measurement program and manually in AgfaWeb1000. Inter-method and inter- and intra-observer agreement were analyzed using the mean differences between the readings/readers, establishing the 95% limits of agreement. We also calculated the minimum detectable change and the intra-class correlation coefficient. Large variations among different radiological measurements were demonstrated. However, the variation was not related to the use of either the manual or digital measurement technique. For measurements with greater absolute values (Sharp's angle, femoral head extrusion index, and acetabular depth-width ratio) the inter- and intra-observer and inter-method agreements were better as compared to measurements with lower absolute values (acetabular roof angle, teardrop and joint space width). The inter- and intra-observer variation differs notably across different radiological measurements relevant for hip dysplasia at skeletal maturity, a fact that should be taken into account in clinical practice. The agreement between the manual and digital methods is good.

    The outcome indicator of nosocomial infection (NI) in the intensive care unit (ICU) is used to benchmark the quality of patient care in Malaysia. We conducted a three-year prospective study on the incidences of ventilator-associated pneumonia (VAP), risk factors, and patterns of the microorganisms isolated in three ICUs. A follow-up in prospective cohort surveillance was conducted on patients admitted to an adult medical-surgical ICU of a university hospital and two governmental hospitals in Malaysia from October 2003 to December 2006. VAP was detected using CDC criteria which included clinical manifestation and confirmed endotracheal secretion culture results. In total, 215 patients (2,306 patient-days) were enrolled into the study. The incidence of ICU-acquired device-related NI was 29.3 % (n = 63). The device-related VAP infection rate was 27.0 % (n = 58), with a mechanical ventilator utilization rate of 88.7%. The death rate due to all ICU-acquired NI including sepsis was 6.5%. The most common causative pathogen was Klebsiella pneumoniae (n = 27). Multivariate analysis using Cox regression showed that the risk factors identified were aspiration pneumonia (HR = 4.09; 95% CI = 1.24, 13.51; P = 0.021), cancer (HR = 2.51; 95% CI = 1.27, 4.97; P = 0.008), leucocytosis (HR=3.43; 95% CI= 1.60, 7.37; P=0.002) and duration of mechanical ventilation (HR=1.04; 95% CI = 1.00, 1.08; P = 0.030). Age, gender and race were not identified as risk factors in the multivariable analysis performed. The incidence of VAP was comparable to that found in the National Nosocomial Infection Surveillance (NNIS) System report of June 1998. The incidence of VAP was considered high for the three hospitals studied.

    Abstract This study was performed to investigate the safety and efficacy of the intra-articular infusion of ex vivo expanded autologous bone marrow-derived mesenchymal stem cells (BM-MSC) to a cohort of patients with articular cartilage defects in the hip. The above rationale is sustained by the notion that MSCs express a chondrocyte differential potential and produce extracellular matrix molecules as well as regulatory signals, that may well contribute to cure the function of the damaged hip joint. A cohort of 10 patients with functional and radiological evidences of hip osteoarthritis, either in one or both legs, was included in the study. BM-MSC (the cell product) were prepared and infused into the damaged articulation(s) of each patient (60 × 106 cells in 3 weekly/doses). Before and after completion of the cell infusion scheme, patients were evaluated (hip scores for pain, stiffness, physical function, range of motion), to assess whether the infusion of the respective cell product was beneficial. The intra-articular injection of three consecutive weekly doses of ex vivo expanded autologous BM-MSC to patients with articular cartilage defects in the hip and proved to be a safe and clinically effective treatment in the restoration of hip function and range of motion. In addition, the statistical significance of the above data is in line with the observation that the radiographic scores (Tönnis Classification of Osteoarthritis) of the damaged leg(s) remained without variation in 9 out of 10 patients, after the administration of the cell product.

    Full Text Available Objective: To evaluate the midterm clinical and radiological outcomes of the medial approach using two intervals for developmental hip dysplasia (DDH. Methods: The study involved 62 hips of 47 patients (41 girls, 6 boys treated with medial approach for DDH from 1999 to 2010. The age of the patients at surgery was 18.7 ± 2.25 months. Follow up of the patients was 11.3 ± 3.07 years. The age of the patients at the last follow up was 12.6 ± 1.74 years. According to the Tönnis classification, 13 hips were grade II, 27 hips were grade III and 22 hips were grade IV. Patients were evaluated according to Omeroglu radiological criteria and modified McKay functional criteria. The presence of avascular necrosis (AVN of the hip was questioned using the KalamchiMacEwen classification. Results: Radiologically, forty eight (77% hips were evaluated as “excellent”, 8 (13% hips as “good” and 5 (8% hips as “fair plus” and 1 (%2 hip as “fair minus”. Two (3% patients had type 1 temporary AVN and one (1% patient had type 4 AVN with coxa magna and overgrowth of the greater trochanter. According to McKay functional criteria, 56 (90% hips had “excellent” and 6 (10% had “good” results. Two (3.2% hips of one patient had to be reoperated with Salter osteotomy and femoral shortening + derotation osteotomy. Conclusion: Medial approach using two separate intervals for tenotomy and capsulotomy does not jeopardize the medial circumflex or the femoral vessels and yields satisfactory midterm results for children 18 months old with dysplasia of the hip.

    It is essential to monitor the utilisation of antibacterial drugs in order to establish appropriate measures for their control. The pattern of usage of antibacterial drugs, and its association with indicators of hospital infection, has been investigated in a non-specialized adult intensive care unit (ICU) located in Santa Luzia Hospital (Brasília, DF, Brazil). The study was conducted between January 2001 and June 2004. Data concerning the utilisation of systemic antibacterial drugs, classified according to the Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD) system, and indicators of hospital infection, defined according to the National Nosocomial Infections Surveillance (NNIS) system, were obtained from appropriate hospital archives. During the study period, the average utilisation of antibacterial drugs was 1918.5 DDD units per 1000 patient-day (DDD(1000)). The three most used drugs were penicillins/beta-lactamase inhibitors (535.3 DDD(1000)), third generation cephalosporins (239.1 DDD(1000)) and quinolones (212.5 DDD(1000)). The total utilisation of antibacterial drugs was correlated significantly with the incidence of hospital infection (R = 0.62; p < 0.01) and the index of invasive procedures (R = 0.41; p < 0.01). Furthermore, the latter two indicators were significantly and positively correlated with the use of recently commercialized, broad spectrum antibacterial drugs (except for carbapenems). It is concluded that improved infection control procedures, together with more rigorous criteria regarding the use of invasive procedures, should be implemented by the ICU studied in order to diminish the utilisation of antibacterial drugs.

The purpose of this study was to Investigation of the relative frequency of NSSIs in healthcare workers (HCWs in Ahvaz, Iran (Razi hospital over 3-year period (2011–2013. Materials and Methods: A descriptive study during 2011-2013 was conducted on 600 HCWs at Razi Hospital, Ahvaz, Iran. To measure NSSIs, has been diagnosis and categorized based on the National Nosocomial Infections Surveillance (NNIS. Data about health workers’ age, sex, site of NSIs injury, ward of hospitalization and case of needle stick were collected. Descriptive statistical by SPSS version 16 used for analyzed data in this study. Results: According to the results of this study, among all nurses, the maximum cases of NSIs were HCWs. Regarding the finding, recapping needle were found in 34.17%, handling needle in 20.25%, suturing in 16.45%, passing needle in 13.92%, transit disposal in 8.86% and dissembling needle in 6.32% of cases. Findings showed that the most NSIs in Razi Hospital were general surgery, emergency, Intensive Care Unit (ICU, Obstetrics and Gynecology (OBGYN, operating room, orthopedic and infectious diseases wards during 2011-2013. Conclusion: Based on these findings, the number of health care-associated with NSIs between nurses in our study may be due to the shortage of nurses, long working hours during the night shift, fatigue and failure to use an appropriate equipment.

    measured from radial MRI sequences was 58° in the LROM group versus 44° in the control group ( P hips (50%) had a positive anterior impingement sign, whereas 0 of 26 hips (0%) had a positive anterior impingement sign in the control group. At 5-year follow-up, 18 of 19 hips (95%) in the LROM group had abnormal MRI findings compared with 14 of 26 hips (54%) in the control group (RR, 1.7; 95% CI, 1.1-2.7; P = .014). New or progressive findings were documented on MRI in 15 of 20 hips in the LROM group compared with 8 of 26 hips in the control group (RR, 2.4; 95% CI, 1.2-4.8; P = .011). Six of 22 hips (27%) in the LROM group progressed from Tönnis grade 0 to Tönnis grade 1 in degenerative changes, whereas all 26 hips in the control group remained at Tönnis grade 0 on hip radiographs. In the LROM group, 11 of 22 hips (50%) had a positive anterior impingement sign, whereas 1 of 26 hips (4%) had a positive anterior impingement sign in the control group. A cam deformity (alpha angle >55° on lateral radiographs) was present in 20 of 22 hips (91%) in the LROM group and 12 of 26 hips (46%) in the control group ( P = .0165). The following variables at baseline were associated with an increased risk of degenerative changes at 5-year follow-up for the entire cohort: decreased hip internal rotation, positive anterior impingement sign, decreased hip flexion, increased alpha angle, and presence of a cam lesion. At 5 years, young athletes with LROM of the hip showed increased progressive degenerative changes on MRI and radiographs compared with matched controls. Although the majority of these participants remained asymptomatic, those with features of FAI had radiographic findings consistent with early osteoarthritis. These outcomes suggest that more aggressive screening and counseling of young active patients may be helpful to prevent hip osteoarthritis in those with FAI.

    (DOpx•Cpx(Lu) = 0.31) towards the LREE (DOpx•Cpx(Nd) = 0.01). The partition coefficients for plagioclase/clinopyroxene and K-feldspar/clinopyroxene in the alkaline melanogabbros decrease from the LREE (DPlg•Cpx(La) = 0.91, DK-fs•Cpx(La)=0.26) to the MREE (DPlg•Cpx(Sm) = 0.02, DK-fs•Cpx(Sm) = 0.006), but both mineral pairs have similar DEu (DPlg•Cpx(Eu) = 0.25, DK-fs•Cpx(Eu) = 0.23). Plagioclase/clinopyroxene partition coefficients for all REE in the tholeiitic gabbros are 3-5 times higher, if compared to those of the alkaline gabbros (DPlg•Cpx(La) = 1.7, DPlg•Cpx(Sm) = 0.034). Apatite/clinopyroxene partition coefficients for the REE decrease from the LREE (DAp•Cpx(La) = 65 in alkaline and 120 in tholeiitic gabbro) to the HREE (DAp•Cpx(Lu) = 4.5 in alkaline and 5.3 in tholeiitic gabbro). The lower partition coefficients for apatite/clinopyroxene and plagioclase/clinopyroxene in the alkaline melanogabbros can be explained by higher clinopyroxene/melt partition coefficients in this system. The higher Al2O3-content in clinopyroxene from the alkali gabbros (Al2O3 = 3.5-7 wt.%), if compared to clinopyroxene in the tholeiitic gabbros (Al2O3 = 2.0-4.5 wt.%) can account for a stronger partitioning of the REE into clinopyroxene in the alkaline rocks (e.g. Gaetani and Grove 1995). Experimental data by Gaetani (2004) also indicate a systematic increase of the Cpx/melt partition coefficients for the REE with increasing Al2O3 and Na2O contents of the parental melt in mafic systems. This is in agreement with the assumed compositional differences between the alkaline and the tholeiitic parental melts. Gaetani, G.A., 2004.

    Full Text Available The genus Enterovirus of the family Picornaviridae contains many important human pathogens (e.g., poliovirus, coxsackievirus, rhinovirus, and enterovirus 71 for which no antiviral drugs are available. The viral RNA-dependent RNA polymerase is an attractive target for antiviral therapy. Nucleoside-based inhibitors have broad-spectrum activity but often exhibit off-target effects. Most non-nucleoside inhibitors (NNIs target surface cavities, which are structurally more flexible than the nucleotide-binding pocket, and hence have a more narrow spectrum of activity and are more prone to resistance development. Here, we report a novel NNI, GPC-N114 (2,2'-[(4-chloro-1,2-phenylenebis(oxy]bis(5-nitro-benzonitrile with broad-spectrum activity against enteroviruses and cardioviruses (another genus in the picornavirus family. Surprisingly, coxsackievirus B3 (CVB3 and poliovirus displayed a high genetic barrier to resistance against GPC-N114. By contrast, EMCV, a cardiovirus, rapidly acquired resistance due to mutations in 3Dpol. In vitro polymerase activity assays showed that GPC-N114 i inhibited the elongation activity of recombinant CVB3 and EMCV 3Dpol, (ii had reduced activity against EMCV 3Dpol with the resistance mutations, and (iii was most efficient in inhibiting 3Dpol when added before the RNA template-primer duplex. Elucidation of a crystal structure of the inhibitor bound to CVB3 3Dpol confirmed the RNA-binding channel as the target for GPC-N114. Docking studies of the compound into the crystal structures of the compound-resistant EMCV 3Dpol mutants suggested that the resistant phenotype is due to subtle changes that interfere with the binding of GPC-N114 but not of the RNA template-primer. In conclusion, this study presents the first NNI that targets the RNA template channel of the picornavirus polymerase and identifies a new pocket that can be used for the design of broad-spectrum inhibitors. Moreover, this study provides important new insight

    The treatment of hip instability in patients with Down syndrome is challenging. We have performed different pelvic osteotomies and corrections at the proximal femur for this indication. This retrospective study was conducted to evaluate the clinical and radiological outcome of each intervention. All in all, 166 patients with Down syndrome were treated at our orthopaedic department in the observation period. Problems related to the hip joint were diagnosed in 63 of those patients. Only patients who underwent surgery were included in this study. The charts and X-rays of these 31 patients were evaluated with respect to the following parameters: incidence of the hip problem, concomitant diseases, temporal progress, kind of operation method and date, duration of stay in the hospital, after-care, follow-on surgery related to complications, AC angle, CE angle, ACM angle, CCD angle, index of migration according to Reimers, classification of Bauer and Kerschbauer and general morphology of the femoral head. The group was compared with an age-matched group of 21 patients with hip dysplasia. Those patients underwent the same sort of operation in the same year. In the Morbus Down group, we performed surgery for preservation of the hip in 49 cases. This included 13 osteotomies according to Chiari, 11 triple osteotomies according to Tönnis, 10 corrections by femoral varus derotation osteotomy, 8 pelvic osteotomies according to Pemberton, 5 pelvic osteotomies according to Salter and 2 open reductions of the hip. With respect to the moment of surgery, we detected three peaks of age. There was no difference in course of disease and quantity of complications between the groups. Satisfactory results concerning clinical and radiological outcome were achieved predominantly by complete redirectional acetabular osteotomies. Half of the patients who were solely treated by femoral varus derotation osteotomy needed follow-on surgery in the form of pelvic osteotomy. Comparison of

Materials and Methods: The study was a point-prevalence study involving over 300 patients. The presence of infection was determined according to the CDC criteria. Swabs were taken from the infected sites and identification and sensitivity were carried out using VITEK® 2 automated system. Characterisation of β-lactamase was carried out at ARRML, Colindale, London. Results: The rate of SSI was 15% for the clean and clean-contaminated categories while that for the dirty contaminated category was 85% (NNIS risk index 0. Cultures yielded definite or probable pathogens from 64% (9/14 of the patients with SSI. In 1/3 rd of the cultures, Staphylococcus aureus was grown and the rest had Enterobacteriaceae, either extended-spectrum β-lactamase (ESBL producers or Amp-C hyperproducers and, alarmingly, three isolates were positive for newly recognised New Delhi metallo-β-lactamase-1 (NDM-1.

    Bovine viral diarrhea virus (BVDV) is the prototype Pestivirus. BVDV infection is distributed worldwide and causes serious problems for the livestock industry. The thiosemicarbazone of 5,6-dimethoxy-1-indanone (TSC) is a non-nucleoside polymerase inhibitor (NNI) of BVDV. All TSC-resistant BVDV variants (BVDV-TSCr T1-5) present an N264D mutation in the NS5B gene (RdRp) whereas the variant BVDV-TSCr T1 also presents an NS5B A392E mutation. In the present study, we carried out twenty passages of BVDV-TSCr T1-5 in MDBK cells in the absence of TSC to evaluate the stability of the resistance. The viral populations obtained (BVDV R1-5) remained resistant to the antiviral compound and conserved the mutations in NS5B associated with this phenotype. Along the passages, BVDV R2, R3 and R5 presented a delay in the production of cytopathic effect that correlated with a decrease in cell apoptosis and intracellular accumulation of viral RNA. The complete genome sequences that encode for NS2 to NS5B, Npro and Erns were analyzed. Additional mutations were detected in the NS5B of BVDV R1, R3 and R4. In both BVDV R2 and R3, most of the mutations found were localized in NS5A, whereas in BVDV R5, the only mutation fixed was NS5A V177A. These results suggest that mutations in NS5A could alter BVDV cytopathogenicity. In conclusion, the stability of the resistance to TSC may be due to the fixation of different compensatory mutations in each BVDV-TSCr. During their replication in a TSC-free medium, some virus populations presented a kind of interaction with the host cell that resembled a persistent infection: decreased cytopathogenicity and viral genome synthesis. This is the first report on the stability of antiviral resistance and on the evolution of NNI-resistant BVDV variants. The results obtained for BVDV-TSCr could also be applied for other NNIs.

    The purpose of this study was to determine the extent of preoperative osteoarthritis (OA) that precludes benefit from hip arthroscopy by systematically reviewing the literature on hip arthroscopy in the setting of OA. We searched the Medline and PubMed databases using the following Medical Subject Heading terms: arthritis, osteoarthritis, chondral damage, chondral injury, chondral delamination, and hip arthroscopy. Two authors independently reviewed the literature and included articles if they were in the English language; commented on preoperative factors, parameters, physical examination, or diagnostic testing that may be evidence of cartilage damage and/or arthritis; contained outcome data on patients undergoing hip arthroscopy; and had a sample size of at least 10 patients with arthritic changes in the hip. We excluded review articles, technique articles, articles with overlapping patient populations, articles with hip arthroscopy used as an adjunct to an open procedure, articles with inflammatory and septic arthritis, and articles with a mean age younger than 18 years. Our search identified 518 articles, of which 15 met the inclusion and exclusion criteria. Two thousand fifty-one hips underwent arthroscopy at a mean patient age of 40.2 years. Of these, 1,195 hips had signs of OA. There were 345 conversions to total hip arthroplasty/surface replacement arthroplasty. Of these patients, 274 had OA. Eight patient-reported outcome instruments were used. Factors influencing outcomes were preoperative OA, age, chondral damage, femoroacetabular impingement, and duration of symptoms. Current evidence is insufficient to define a cutoff for how much arthritis is too much for hip arthroscopy. However, this analysis shows that patients with a Tönnis grade of 1 or greater or a joint space of 2 mm or less are less likely to benefit from hip arthroscopy and more likely to require conversion to total hip arthroplasty/surface replacement arthroplasty.

    To report the minimum 5-year outcomes of endoscopic gluteus medius repair for partial- and full-thickness tears with concomitant hip arthroscopy. Data for all patients who underwent hip arthroscopy between February 2009 and September 2011 were prospectively collected. We included patients who underwent endoscopic gluteus medius repair with concomitant arthroscopic labral treatment and for whom the following measures were obtained preoperatively and at a minimum of 5 years' follow-up: modified Harris Hip Score, Non-Arthritic Hip Score, Hip Outcome Score-Sports Specific Subscale, and visual analog scale score for pain. For included patients, the International Hip Outcome Tool-12 (iHOT-12) score and satisfaction rating were also available at latest follow-up. Patients with at least 1 of the following criteria were excluded: preoperative Tönnis osteoarthritis grade of 2 or greater, previous hip conditions, severe dysplasia, and Workers' Compensation claims. There were 16 patients eligible for inclusion, 14 (87.5%) of whom had minimum 5-year follow-up, with a mean of 68.8 months (range, 60.1-79.6 months). The study group consisted of 13 women (92.9%) and 1 man (7.1%) with a mean age at surgery of 57.4 years (range, 46.3-74.8 years). Outcome scores improved as follows: modified Harris Hip Score, from 52.4 to 81.2 (P = .004); Non-Arthritic Hip Score, from 48.0 to 82.5 (P = .002); Hip Outcome Score-Sports Specific Subscale, from 30.1 to 66.4 (P arthroscopy for labral tears is safe and shows favorable outcomes at minimum 5-year follow-up. Patient outcomes were as favorable at 5 years as they were at 2 years postoperatively. Level IV, therapeutic case series. Copyright © 2017 Arthroscopy Association of North America.

    To determine prevalence, magnitude, and predisposing radiographic features of hip subluxation in elite ballet dancers. A cross-sectional investigation of professional male and female ballet dancers was performed using 5 plain radiographs. A "splits" anteroposterior (AP) radiograph was performed with legs abducted parallel to the trunk in the coronal plane (splits position; grand écart facial). Hip center position (HCP) was measured on standing AP pelvis and AP pelvis splits views and the difference calculated (subluxation distance) to determine prevalence and magnitude of femoral head subluxation. Student t test compared HCP on AP pelvis and splits radiographs. Pearson correlations were used to correlate splits HCP with radiographic measures of femoroacetabular impingement and dysplasia. Analyzing 47 dancers (21 men, 26 women; 23.8 ± 5.4 years), mean HCP on standing AP pelvis was 9.39 ± 3.33 mm versus 10.8 ± 2.92 mm on splits radiograph, with mean subluxation distance of 1.41 mm (P = .035). Forty-two dancers' femoral heads translated laterally with splits positioning, and 17 dancers (36%) exhibited a "vacuum sign" (bilateral in 71% of subjects with at least 1 hip vacuum sign). There was strong positive correlation (r = 0.461, P = .001) with splits HCP and alpha angle (Dunn 45°), and moderate negative correlation (r = -0.332, P = .022) with subluxation distance and neck-shaft angle. In men, splits HCP increased as lateral center edge angle (CEA) decreased (r = -0.437, P = .047), as anterior CEA decreased (r = -0.482, P = .027), as Tönnis angle increased (r = 0.656, P = .001), and as femoral head extrusion index increased (r = 0.511, P = .018). In women, there was moderate negative correlation (r = -0.389, P = .049) with subluxation distance and neck-shaft angle. Hip subluxation occurs during splits in most professional ballet dancers, with a significantly greater magnitude of subluxation in women than men. Subluxation magnitude

    To define the feasibility of utilizing T2* mapping for assessment of early cartilage degeneration prior to surgery in patients with symptomatic femoroacetabular impingement (FAI), we compared cartilage of the hip joint in patients with FAI and healthy volunteers using T2* mapping at 3.0 Tesla over time. Twenty-two patients (13 females and 9 males; mean age 28.1 years) with clinical signs of FAI and Tönnis grade ≤ 1 on anterior-posterior x-ray and 35 healthy age-matched volunteers were examined at a 3 T MRI using a flexible body coil. T2* maps were calculated from sagittal- and coronal-oriented gradient-multi-echo sequences using six echoes (TR 125, TE 4.41/8.49/12.57/16.65/20.73/24.81, scan time 4.02 min), both measured at beginning and end of the scan (45 min time span between measurements). Region of interest analysis was manually performed on four consecutive slices for superior and anterior cartilage. Mean T2* values were compared among patients and volunteers, as well as over time using analysis of variance and Student's t-test. Whereas quantitative T2* values for the first measurement did not reveal significant differences between patients and volunteers, either for sagittal (p = 0.644) or coronal images (p = 0.987), at the first measurement, a highly significant difference (p ≤ 0.004) was found for both measurements with time after unloading of the joint. Over time we found decreasing mean T2* values for patients, in contrast to increasing mean T2* relaxation times in volunteers. The study proved the feasibility of utilizing T2* mapping for assessment of early cartilage degeneration in the hip joint in FAI patients at 3 Tesla to predict possible success of joint-preserving surgery. However, we suggest the time point for measuring T2* as an MR biomarker for cartilage and the changes in T2* over time to be of crucial importance for designing an MR protocol in patients with FAI.

    Full Text Available Background: Intensive Therapeutic Units (ITUs are unfortunately the epicenters of hospital acquired infection (HAIs. Limited data is available regarding the burden of HAIs in Indian ITU, especially median time of its detection, prevalent organisms and its resistance patterns. We conducted a prospective surveillance aimed to determine the occurrence of device associated infections (DAIs rate, magnitude of device associated infection cases per 1000 bed days, incidence of infections per 1000 device days and median time for detection of DAIs. Study population was taken from a 25 bedded intensive therapeutic unit (ITU, of a government teaching hospital in India. Methods: A prospective cohort study was performed over two years duration from June 2011 to May 2013. Total 596 patients who were admitted in the ITU for more than 48 hours were followed until discharge. CDC/NNIS system definitions for DAIs were used and rates were calculated. Data were analyzed with descriptive statistics. Results: Cumulative incidence rate of HAIs was 23.15 (138/596 and isolated DAIs was 19.96 (119/596. There was high device utilization mainly for urinary catheter (.838 and IV catheter (.742 than ventilator (.310 but the incidence density was more in ventilator associated infection(VAP-7.38% than catheter associated urinary tract infection (CAUTI-7.21% and catheter related blood stream infection (CRBSI-5.37%.

    Full Text Available OBJECTIVES: To measure device-associated infection (DAI rates, microbiological profiles, bacterial resistance, extra length of stay, and attributable mortality in intensive care units (ICUs in three Brazilian hospitals that are members of the International Nosocomial Infection Control Consortium (INICC. METHODS: Prospective cohort surveillance of DAIs was conducted in five ICUs in three city hospitals in Brazil by applying the definitions of the U.S. Centers for Disease Control and Prevention National Nosocomial Infections Surveillance System (CDC-NNIS. RESULTS: Between April 2003 and February 2006, 1 031 patients hospitalized in five ICUs for an aggregate 10 293 days acquired 307 DAIs, a rate of 29.8% or 29.8 DAIs per 1 000 ICU-days. The ventilator-associated pneumonia (VAP rate was 20.9 per 1 000 ventilator-days; the rate for central venous catheter-associated bloodstream infections (CVC-BSI was 9.1 per 1 000 catheter-days; and the rate for catheter-associated urinary tract infections (CAUTI was 9.6 per 1 000 catheter-days. Ninety-five percent of all Staphylococcus aureus DAIs were caused by methicillin-resistant strains. Infections caused by Enterobacteriaceae were resistant to ceftriaxone in 96.7% of cases, resistant to ceftazidime in 79.3% of cases, and resistant to piperacillin-tazobactam in 85.7% of cases. Pseudomonas aeruginosa DAIs were resistant to ciprofloxacin in 71.3% of cases, resistant to ceftazidime in 75.5% of cases, and resistant to imipenem in 27.7% of cases. Patients with DAIs in the ICUs of the hospitals included in this study presented extra mortality rates of 15.3% (RR 1.79, P = 0.0149 for VAP, 27.8% (RR 2.44, P = 0.0004 for CVC-BSI, and 10.7% (RR 1.56, P = 0.2875 for CAUTI. CONCLUSION: The DAI rates were high in the ICUs of the Brazilian hospitals included in this study. Patient safety can be improved through the implementation of an active infection control program comprising surveillance of DAIs and infection prevention

    Age has been suggested as a negative prognostic factor for hip arthroscopy. The purpose of this study was to compare patient characteristics and outcomes after hip arthroscopy in patients aged 50 years or older with a matched control group of patients aged 30 years or younger at a minimum postoperative follow-up of 2 years. Between September 2008 and March 2010, data were prospectively collected on all patients aged 50 years or older undergoing primary hip arthroscopy. Fifty-two patients met our inclusion and matching criteria, of whom all 52 (100%) were available for follow-up at a minimum of 2 years. This cohort was compared with a matched-pair control group of patients aged 30 years or younger who underwent similar procedures. The mean age of the study group was 54.8 years (range, 50 to 69 years), and that of the control group was 20.3 years (range, 13 to 30 years). The groups were matched at a 1:1 ratio, including 18 male patients (34.6%) and 34 female patients (65.4%) in each group, with a mean follow-up period of 32 months (range, 24 to 54 months). In the younger control group, the score improvement from preoperatively to 2 years' follow-up was 62.9 to 84.2 for the modified Harris Hip Score, 60.5 to 84.2 for the Non-Arthritic Hip Score, 63.1 to 86.5 for the Hip Outcome Score-Activities of Daily Living, and 42.2 to 72.7 for the Hip Outcome Score-Sport-Specific Subscale. In the older study group, the score improvement from preoperatively to 2 years' follow-up was 61.2 to 82.2 for the modified Harris Hip Score, 59.9 to 80.4 for the Non-Arthritic Hip Score, 63.9 to 83 for the Hip Outcome Score-Activities of Daily Living, and 41.2 to 64.6 for the Hip Outcome Score-Sport-Specific Subscale. All improvements in both groups were statistically significant at the 2-year postoperative follow-up (P arthroscopy should be considered a valid treatment option when treating hip pain in patients aged 50 years or older with a Tönnis arthritic grade of 0 or 1.

  5. Is DDH still a problem?

    Full Text Available Developmental dysplasia of the hip (DDH is the most frequent developmental disorder of the locomotor system. It is detected among 0.1–5.2% of newborns (1, 2. This might be the reason, that there is a high interest to detect DDH cases as early as possible. Undetected or late cases lead to catastrophes for the patient and family. Limping, leg length discrepancy, pain, frequent operations and sometimes femoral head necrosis, osteoarthritis, disability and finally total hip replacement even in young ages are results of a dysplastic hip that is not diagnosed on time or left untreated or treated improperly. Independent from individual patient problems the treatment costs for late or neglected cases are enormous. Costs of hospitalization, operations, rehabilitation, and indirect costs because of limited ability to work are incredible high. In countries with poor common health-system these patients have no chance for a normal life because of their disability.   How to solve or reduce the problem Clinical examination (Ortolani,Barlow etc. is used very often in different countries routinely, but not generally worldwide. The literature is quite clear; clinical examinations can reduce but not solve the problem. It need “well trained and experienced doctors”! But what is the definition of a “well trained and experienced doctor”? How it can happen, that in spite of clinical examination we see neglected cases? More than 5o% of DDH cases does not have any “typical” risk factor. The clinical examination is very often so subjective, that even fully dislocated joints cannot be detected and may be missed.   Critical questions 1- What is the Ortolani and the Barlow sign, the Glissement, the dry click sign, the phenomenon of the loose joint capsule and the “click” according to Tönnis D? 2- What sign in what age is normal? When does one of these signs change to the other one? 3- What is the pathology inside the joints, when you feel one of these

    grade or more on the Tönnis score), and a Merle d'Aubigné-Postel score < 15. At the 10-year followup, hip pain in hips with labral reattachment was slightly improved for the postoperative Merle d'Aubigné-Postel pain subscore (5.0 ± 1.0 [3-6] versus 3.9 ± 1.7 [0-6]; p = 0.017). No difference existed for the prevalence of hip pain assessed using the anterior impingement test with the numbers available (resection group 52% [11 of 21 hips] versus reattachment group 27% [eight of 30 hips]; odds ratio, 3.03; 95% confidence interval [CI], 0.93-9.83; p = 0.062). Function was slightly better in the reattachment group for the overall Merle d'Aubigné-Postel score (16.7 ± 1.5 [13-18] versus 15.3 ± 2.4 [9-18]; p = 0.028) and hip abduction (45° ± 13° [range, 30°-70°] versus 38° ± 8° [range, 25°-45°]; p = 0.001). Hips with labral reattachment showed a better survival rate at 10 years than did hips that underwent labral resection (78%; 95% CI, 64%-92% versus 46%, 95% CI, 26%-66%; p = 0.009) with the endpoints defined as conversion to THA, progression of osteoarthritis, and a Merle d'Aubigné-Postel score < 15. With isolated endpoints, survival at 10 years was increased for labral reattachment and the endpoint Merle d'Aubigné score < 15 (83%, 95% CI, 70%-97% versus 48%, 95% CI, 28%-69%; p = 0.009) but did not differ for progression of osteoarthritis (83%, 95% CI, 68%-97% versus 81%, 95% CI, 63%-98%; p = 0.957) or conversion to THA (94%, 95% CI, 86%-100% versus 87%, 95% CI, 74%-100%; p = 0.366). The current results suggest the importance of preserving the labrum and show that resection may put the hip at risk for early deterioration. At 10-year followup, hips with labral reattachment less frequently had a decreased Merle d'Aubigné score but no effect on progression of osteoarthritis or conversion to THA could be shown. Level III, therapeutic study.
