    Amnioinfusion is a relatively recent procedure introduced among fetal medicine techniques. Its applications focus on two different methods: transcervical and transabdominal. The first procedure usually is carried out during "intrapartum amnioinfusion" to prevent or treat fetal heart rate (FHR) decelerations related to oligohydramnios or to dilute thick meconium staining of the amniotic fluid. The latter method used during "antepartum amnioinfusion" is usually indicated for severe oligohydramnios in order to avoid the complications related such as pulmonary hypoplasia, deforming effects of oligohydramnios, variable FHR decelerations and intraventricular hemorrhages. Antepartum amnioinfusion, also used to improve ultrasound visualisation in presence of oligohydramnios, is less employed as compared to intrapartum amnioinfusion, therefore its risks are not well established. In order to study possible adverse effects on the mother or foetus, fifty five patients affected by oligohydramnios at 17th-34th week of gestational age were submitted to antepartum amnioinfusion (1-5 procedures) and were matched retrospectively with forty seven women with the same characteristics treated with the conservative and expectant management. The trend of pregnancy was the same for both groups in relation to maternal fever > 38 degrees (10.9% in the amnioinfused group vs 17.0% in control group ns), leukocyte count > 18,000/mm3 (25.5% vs 21.3%, ns), C-reactive protein > 10 ng/ml (10.9% vs 6.4%, ns). The latency period between admission and delivery was significantly longer in the amnioinfused group than in the control one [21 (range 1-98) vs 9 days (range 0-72); p amnioinfused group than in the control group (32.3% vs 66.6%; p amnioinfusion seems to increase the latency period between premature rupture of membranes and delivery, but it remains to clarify if this procedure is as much safe for the fetus as for the mother.

    This study is the result of two Portuguese case-control studies that examined the replication of retrospective correlates and preceding life events in anorexia nervosa (AN) and bulimia nervosa (BN) development. This study aims to identify retrospective correlates that distinguish AN and BN METHOD: A case-control design was used to compare a group of women who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for AN (N = 98) and BN (N = 79) with healthy controls (N = 86) and with other psychiatric disorders (N = 68). Each control group was matched with AN patients regarding age and parental social categories. Risk factors were assessed by interviewing each person with the Oxford Risk Factor Interview. Compared to AN, women with BN reported significantly higher rates of paternal high expectations, excessive family importance placed on fitness/keeping in shape, and negative consequences due to adolescent overweight and adolescent objective overweight. Overweight during adolescence emerged as the most relevant retrospective correlate in the distinction between BN and AN participants. Family expectations and the importance placed on keeping in shape were also significant retrospective correlates in the BN group.

    This retrospective study aimed at determining prognostic factors that paved the way for umbilical cord entanglement (UCE) and the effects of UCE upon labor management and fetal health. Sixty women who gave term birth with head presentation and received UCE diagnosis following birth composed the case group while another 60 women with the same characteristics who were selected with randomized sampling method and who did not develop UCE comprised the control group. The data obtained were processed with SPSS 22.0 statistical program. T test was used for comparing demographic and obstetric data and mean birth weight of babies in the case group and control group. For comparing data on active labor management and fetal health, numbers, percentages and chi-square test were used. Also for comparing values case: 58.3.0%; control: 21.7%), vacuum assisted vaginal delivery (case: 20.0%; control: 3.3%), forceps assisted vaginal delivery (case: 8.3%; control: 1.7%), fetal distress (case: 60.0%; control: 25.0%), amniotic fluid meconium (case: 58.3%; control: 21.7%), APGAR score less than 7 at the 1st minute (case: 58.3%; control: 21.7%) and APGAR score less than 7 at the 5th minute were higher in the women in the case group than the women in the control group (p < 0.05). UCE increased rates of interventional birth, emergent cesarean delivery, vacuum assisted vaginal delivery, forceps assisted vaginal delivery, amniotic fluid meconium and fetal distress.

    Psychogenic nonepileptic seizures (PNES) can be challenging to diagnose, but certain clinical features can help to distinguish PNES from epileptic seizures. The purpose of this study is to assess chronic pain and prescribed pain medication use in PNES patients. A case-controlled, retrospective analysis was performed examining pain medication use in 85 PNES patients versus an active control group of 85 patients with idiopathic generalized epilepsy (IGE). Chronic pain was more frequent among PNES patients (N=40) than active controls (N=10) (pseizures raises the possibility of PNES. Among patients with PNES and chronic pain, a psychogenic etiology for pain and non-opiate pain management strategies should be considered. Copyright © 2012 Elsevier Inc. All rights reserved.

    The diagnosis of gall bladder mucoceles (GM) in dogs has become increasingly frequent in veterinary medicine. Primary breed-specific hyperlipidaemia is reported in Shetland Sheepdogs and Miniature Schnauzers, breeds in which GM are known to occur more frequently than in other breeds. The objective of this study was to evaluate the association between GM and hyperlipidaemia in dogs. The study design was a retrospective case control study. Medical records of dogs diagnosed with GM at the Veterinary Medical Centre of The University of Tokyo between 1 April 2007 and 31 March 2012, were reviewed. Fifty-eight dogs with GM and a record of either serum cholesterol, triglyceride, or glucose concentrations were included in the study. Hypercholesterolaemia (15/37 cases; odds ratio [OR]: 2.92; 95% confidence interval [CI]: 1.02-8.36) and hypertriglyceridaemia (13/24 cases; OR: 3.55; 95% CI:1.12-15.91) showed significant association with GM. Pomeranians (OR: 10.69), American Cocker Spaniels (OR: 8.94), Shetland Sheepdogs (OR: 6.21), Miniature Schnauzers (OR: 5.23), and Chihuahuas (OR: 3.06) were significantly predisposed to GM. Thirty-nine out of 58 cases had at least one concurrent disease, including pancreatitis (five cases), hyperadrenocorticism (two cases), and hypothyroidism (two cases). A significant association between GM and hyperlipidaemia was confirmed, suggesting that hyperlipidaemia may play a role in the pathogenesis of GM. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available In developing countries, there is no published report on predicting factors of severe sepsis in severely acute malnourished (SAM children having pneumonia and impact of fluid resuscitation in such children. Thus, we aimed to identify predicting factors for severe sepsis and assess the outcome of fluid resuscitation of such children.In this retrospective case-control study SAM children aged 0-59 months, admitted to the Intensive Care Unit (ICU of the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh from April 2011 through July 2012 with history of cough or difficult breathing and radiologic pneumonia, who were assessed for severe sepsis at admission constituted the study population. We compared the pneumonic SAM children with severe sepsis (cases = 50 with those without severe sepsis (controls = 354. Severe sepsis was defined with objective clinical criteria and managed with fluid resuscitation, in addition to antibiotic and other supportive therapy, following the standard hospital guideline, which is very similar to the WHO guideline.The case-fatality-rate was significantly higher among the cases than the controls (40% vs. 4%; p<0.001. In logistic regression analysis after adjusting for potential confounders, lack of BCG vaccination, drowsiness, abdominal distension, acute kidney injury, and metabolic acidosis at admission remained as independent predicting factors for severe sepsis in pneumonic SAM children (p<0.05 for all comparisons.We noted a much higher case fatality among under-five SAM children with pneumonia and severe sepsis who required fluid resuscitation in addition to standard antibiotic and other supportive therapy compared to those without severe sepsis. Independent risk factors and outcome of the management of severe sepsis in our study children highlight the importance for defining optimal fluid resuscitation therapy aiming at reducing the case fatality in such children.

    Intrauterine hematomas are a common pregnancy complication. The literature lacks studies about outcomes based on hematoma localization. Thus, we aimed to compare pregnancies complicated by an intraplacental hematoma to cases with a retroplacental hematoma and to a control group. In a retrospective case-control study, 32 women with an intraplacental hematoma, 199 women with a retroplacental hematoma, and a control group consisting of 113 age-matched women with no signs of placental abnormalities were included. Main outcome measures were pregnancy complications. Second-trimester miscarriage was most common in the intraplacental hematoma group (9.4%), followed by women with a retroplacental hematoma (4.2%), and controls (0%; p = 0.007). The intraplacental hematoma group revealed the highest rates for placental insufficiency, intrauterine growth retardation, premature preterm rupture of membranes, preterm labor, preterm delivery hematoma group. When tested in multivariate models, intraplacental hematomas were independent predictors for placental insufficiency (ß = 4.19, p hematoma (p = 0.042). Intra- and retroplacental hematomas have different risk profiles for the affected pregnancy and act as independent risk factors.

    Background: Pregnancy-associated nasopharyngeal carcinoma (PANPC) has been associated with poor survival. Recent advances in radiation technology and imaging techniques, and the introduction of chemotherapy have improved survival in nasopharyngeal carcinoma (NPC); however, it is not clear whether these changes have improved survival in PANPC. Therefore, the purpose of this study was to compare five-year maternal survival in patients with PANPC and non-pregnant patients with NPC. Methods: After adjusting for age, stage and chemotherapy mode, we conducted a retrospective case-control study among 36 non-metastatic PANPC patients and 36 non-pregnant NPC patients (control group) who were treated at our institution between 2000 and 2010. Results: The median age of both groups was 30 years (range, 23–35 years); median follow-up for all patients was 70 months. Locoregionally-advanced disease accounted for 83.3% of all patients with PANPC and 92.9% of patients who developed NPC during pregnancy. In both the PANPC and control groups, 31 patients (86.1%) received chemotherapy and all patients received definitive radiotherapy. The five-year rates for overall survival (70% vs. 78%, p = 0.72), distant metastasis-free survival (79% vs. 76%, p = 0.77), loco-regional relapse-free survival (97% vs. 91%, p = 0.69) and disease-free survival (69% vs. 74%, p = 0.98) were not significantly different between the PANPC and control groups. Multivariate analysis using a Cox proportional hazards model revealed that only N-classification was significantly associated with five-year OS. Conclusion: This study demonstrates that, in the modern treatment era, pregnancy itself may not negatively influence survival outcomes in patients with NPC; however, pregnancy may delay the diagnosis of NPC

    Background Several studies in the UK have suggested that women with learning disabilities may be less likely to receive cervical screening tests and a previous local study in had found that GPs considered screening unnecessary for women with learning disabilities. This study set out to ascertain whether women with learning disabilities are more likely to be ceased from a cervical screening programme than women without; and to examine the reasons given for ceasing women with learning disabilities. It was carried out in Bury, Heywood-and-Middleton and Rochdale. Methods Carried out using retrospective cohort study methods, women with learning disabilities were identified by Read code; and their cervical screening records were compared with the Call-and-Recall records of women without learning disabilities in order to examine their screening histories. Analysis was carried out using case-control methods – 1:2 (women with learning disabilities: women without learning disabilities), calculating odds ratios. Results 267 women's records were compared with the records of 534 women without learning disabilities. Women with learning disabilities had an odds ratio (OR) of 0.48 (Confidence Interval (CI) 0.38 – 0.58; X2: 72.227; p.value learning disabilities. Conclusion The reasons given for ceasing and/or not screening suggest that merely being coded as having a learning disability is not the sole reason for these actions. There are training needs among smear takers regarding appropriate reasons not to screen and providing screening for women with learning disabilities. PMID:18218106

    Full Text Available Metformin is increasingly being used a therapeutic option for the management of gestational diabetes mellitus (GDM. The aim of this study was to compare the maternal characteristics and perinatal outcomes of women with GDM treated with metformin (with or without supplemental insulin with those receiving other management approaches. A retrospective, case-control study was carried out and 83 women taking metformin were matched 1:1 with women receiving insulin or diet and lifestyle modification alone. Women managed with diet and lifestyle modification had a significantly lower fasting plasma glucose (p < 0.001 and HbA1c (p < 0.01 at diagnosis of GDM. Furthermore, women managed with metformin had a higher early pregnancy body mass index (BMI compared to those receiving insulin or diet and lifestyle modification (p < 0.001. There was no difference in mode of delivery, birth weight or incidence of large- or small-for-gestational-age neonates between groups. Women receiving glucose lowering therapies had a higher rate of neonatal hypoglycaemia (p < 0.05. The incidence of other adverse perinatal outcomes was similar between groups. Despite their greater BMI, women with metformin-treated GDM did not have an increased risk of adverse perinatal outcomes. Metformin is a useful alternative to insulin in the management of GDM.

The purpose of our study was to assess the actual incidence of anterior cervical spine procedure-associated complications and identify any predisposing factors. A total of 114 patients undergoing anterior cervical procedures over a 6-year period were included in our retrospective, case-control study. The diagnosis was cervical radiculopathy, and/or myelopathy due to degenerative disc disease, cervical spondylosis, or traumatic cervical spine injury. All our participants underwent surgical treatment, and complications were recorded. The most commonly performed procedure (79%) was anterior cervical discectomy and fusion (ACDF). Fourteen patients (12.3%) underwent anterior cervical corpectomy and interbody fusion, seven (6.1%) ACDF with plating, two (1.7%) odontoid screw fixation, and one anterior removal of osteophytes for severe Forestier's disease. Mean follow-up time was 42.5 months (range, 6-78 months). The overall complication rate was 13.2%. Specifically, we encountered adjacent intervertebral disc degeneration in 2.7% of our cases, dysphagia in 1.7%, postoperative soft tissue swelling and hematoma in 1.7%, and dural penetration in 1.7%. Additionally, esophageal perforation was observed in 0.9%, aggravation of preexisting myelopathy in 0.9%, symptomatic recurrent laryngeal nerve palsy in 0.9%, mechanical failure in 0.9%, and superficial wound infection in 0.9%. In the vast majority anterior cervical spine surgery-associated complications are minor, requiring no further intervention. Awareness, early recognition, and appropriate management, are of paramount importance for improving the patients' overall functional outcome.

    Previous studies have observed an association between unmarried status of the mother and adverse perinatal outcome such as increased rate of preterm deliveries, low birthweight and small-for-gestational-age infants. In Israel, attendance of prenatal care is imposed by the state and is not related to socioeconomic status; therefore, unmarried women are expected to have a similar prenatal care as married women. The objective of this study is to test the hypothesis that unmarried and married pregnant women have a similar perinatal outcome. In a retrospective case-control study, analysis of the records of women who gave birth at the delivery ward of Edith Wolfson Medical Center (a tertiary health care center) over a one-year period (2005) with respect to marital status was performed. The cases group included 304 unmarried women who were matched with 1:1 ratio for maternal age, parity, and number of fetuses in the current pregnancy. Unmarried women (n = 304) were more likely to smoke during pregnancy (35.2% vs 15.2%, P vs 54.4 ± 4.4 min, P vs 421.0 ± 25.3 min P unmarried women had similar length of gestation, preterm delivery rate, mode of delivery, low birthweight rates, low Apgar scores or meconium passage during labor as married women. In Israel, unmarried and married pregnant women may have almost similar pregnancy outcomes on length of gestation, mode of delivery and Apgar score. © 2010 The Authors.

    Integrative omics, the joint analysis of outcome and multiple types of omics data, such as genomics, epigenomics, and transcriptomics data, constitute a promising approach for powerful and biologically relevant association studies. These studies often employ a case-control design, and often include nonomics covariates, such as age and gender, that may modify the underlying omics risk factors. An open question is how to best integrate multiple omics and nonomics information to maximize statistical power in case-control studies that ascertain individuals based on the phenotype. Recent work on integrative omics have used prospective approaches, modeling case-control status conditional on omics, and nonomics risk factors. Compared to univariate approaches, jointly analyzing multiple risk factors with a prospective approach increases power in nonascertained cohorts. However, these prospective approaches often lose power in case-control studies. In this article, we propose a novel statistical method for integrating multiple omics and nonomics factors in case-control association studies. Our method is based on a retrospective likelihood function that models the joint distribution of omics and nonomics factors conditional on case-control status. The new method provides accurate control of Type I error rate and has increased efficiency over prospective approaches in both simulated and real data. © 2015 Wiley Periodicals, Inc.

    Burning mouth syndrome (BMS) can be defined as burning pain or dysesthesia on the tongue and/or other sites of the oral mucosa without a causative identifiable lesion. The discomfort is usually of daily recurrence, with a higher incidence among people aged 50 to 60 years, affecting mostly the female sex and diminishing their quality of life. The aim of this study was to evaluate the association between several pathogenic factors and burning mouth syndrome. 736 medical records of patients diagnosed of burning mouth syndrome and 132 medical records for the control group were studied retrospectively. The study time span was from January 1990 to December 2014. The protocol included: sex, age, type of oral discomfort and location, among other factors. Analysis of the association between pathogenic factors and BMS diagnosis revealed that only 3 factors showed a statistically significant association: triggers (P=.003), parafunctional habits (P=.006), and oral hygiene (P=.012). There were neither statistically significant differences in BMS incidence between sex groups (P=.408) nor association of BMS with the pathogenic factors of substance abuse (P=.915), systemic pathology (P=.685), and dietary habits (P=.904). Parafunctional habits like bruxism and abnormal movements of tongue and lips can explain the BMS main symptomatology. Psychological aspects and systemic factors should be always considered. As a multifactorial disorder, the treatment of BMS should be executed in a holistic way. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    Skilled birth attendance is critical in the provision of child birth related services. Yet, literature is scanty on the outcomes of child birth related complications in situations where majority of women deliver under the care of non-skilled birth attendants compared to those who are assisted by skilled providers. The study sought to assess the nature of childbirth related complications among the skilled and the non-skilled birth attendants in Western Kenya. A case-control study was conducted among women aged 15-49 years at the household. Controls were individually matched to cases on the basis of age and socio-economic status. A total of 294 cases and 291 controls were interviewed. Data were collected on various demographic and socio-economic characteristics and women's perception on the quality of care. All independent variables were analysed initially in bivariate models and those that were significantly associated with obstetric complications were included in multiple logistic regression model in order to control for confounding factors. Odds ratios (ORs), with 95% confidence intervals, were computed to show the association between the occurrence, magnitude and the extent to which child birth related complications were managed. Demographic and socio-economic characteristics of the cases and controls were similar. About 52% of the deliveries were assisted by skilled birth attendants while non-skilled providers attended to 48% of them. The odds of the occurrence of obstetric complications were greater among the women who were attended to by skilled providers in health facilities: adjusted odds ratio (AOR): 1.32 (CI 0.95, 1.84) than among those who were assisted by unskilled birth attendants, AOR 0.76 (CI 0.55, 1.06). Undignified care, high delivery and transport costs and fear of hospital procedures such as HIV tests and mishandling of the placenta were cited as some of the barriers to facility deliveries. Skilled birth attendants in facilities were associated

    About 45% of civilians who died by suicide had contact with a doctor within 1 month of death. Thus, educating primary care physicians (PCP) to detect and mitigate depression is an important suicide-prevention strategy. However, the PCP consulting rate before suicide has not been examined in a military population. We investigated the utilization of primary health care and mental health services by active-duty military personnel suicide cases prior to death in comparison to matched military controls. All suicides (N = 170) were extracted from a cohort of all active-duty Israeli military male personnel between 2002 and 2012. Applying a retrospective, nested case-control design, we compared primary care services utilization by suicide cases with demographic and occupationally matched military controls (N = 500). Whereas 38.3% of suicide cases contacted a PCP within the last month before death, only 27.6% of suicide cases contacted a mental health specialist during their entire service time. The PCP contact rate within 1 month before death or index day did not differ between suicide cases and military controls (38.3% vs. 33.8%, χ²₁ = 1.05, P = .3). More suicide cases contacted a mental health specialist within service time than did military controls (27.6% vs. 13.6%, χ²₁ = 10.85, P = .001). Even though PCP contact rate by military personnel who died by suicide is slightly lower than that reported for civilians who died by suicide prior to their death, it is higher than mental health specialist contact rate and higher than that by age-matched civilians who died by suicide. These results imply that PCPs education is a viable approach to suicide prevention in a military setting. © Copyright 2014 Physicians Postgraduate Press, Inc.

    To compare the fluid management of hypernatraemic dehydration in acute gastroenteritis in those who developed cerebral oedema (cases) versus those who did not (controls). A retrospective study of 97 cases of hypernatraemic dehydration at a tertiary children's hospital in China over five years, in which rehydration regimes of 49 children who developed cerebral oedema were compared with 48 children who made an uneventful recovery. Risk factors for cerebral oedema (vs. no cerebral oedema) were an initial fluid bolus (29/49 vs. 15/48, P=0.006), the mean rate of bolus infusion (14.7+/-2.2 vs. 10.8+/-1.4 mL/kg/hr, Pdehydration were too rapid a rate of rehydration, an initial fluid bolus to rapidly expand plasma volume and the severity of the hypernatraemia. Thus, we conclude that a uniformly slow rate of rehydration is the best way of preventing cerebral oedema.

    In epidemiologic studies on lung cancer risk due to indoor radon the quantification of individual radon exposure over a long time period is one of the main issues. Therefore, radon measurements in one or more dwellings, which in total have been inhabited by the participants for a sufficient time-period, are necessary as well as consideration of changes of building characteristics and ventilation habits, which influence radon concentration. Given data on 1-y alpha-track measurements and personal information from 6,000 participants of case-control studies in West and East Germany, and improved method is developed to assess individual radon exposure histories. Times spent in different rooms of the dwelling, which are known from a personal questionnaire, are taken into account. The time spent outside the house varies substantially among the participants. Therefore, assuming a substantially lower radon exposure outside the dwelling, the residence time constitutes an important aspect of total radon exposure. By means of an analysis of variance, important determinants of indoor radon are identified, namely constant conditions such as type of house, type of construction, year of construction, floor and type of basement, and changeable conditions such as heating system, window insulation, and airing habits. A correction of measurements in former dwellings by factors derived from the analysis is applied if current living conditions differ from those of the participants at the time when they were living in the particular dwellings. In rare cases the adjustment for changes leads to a correction of the measurements with a factor of about 1.4, but a reduction of 5% on average only. Exposure assessment can be improved by considering time at home and changes of building and ventilation conditions that affect radon concentration. The major concern that changes in ventilation habits and building conditions lead to substantial errors in exposure assessment cannot be confirmed in the

    The aim of this study was to investigate the characteristics of the risk factors for anorexia nervosa (AN) in Korean women. Two sets of case-control comparisons were conducted, in which 52 women with lifetime AN from Seoul, S. Korea, were compared with 108 Korean healthy controls and also with 42 women with lifetime AN from the UK in terms of their childhood risk factors. A questionnaire designed to conduct a retrospective assessment of the childhood risk factors was administered to all participants. The Korean AN women were more likely to report premorbid anxiety, perfectionism, and emotional undereating and were less likely to report having supportive figures in their childhood than the Korean healthy controls. There were no overall differences in the childhood risk factors between the Korean and British women with AN. Premorbid anxiety, perfectionism, less social support, and emotional undereating merit attention as risk factors in Korean AN. The current results are informative, but an epidemiologically robust prospective case-control study would be needed to validate these findings. © 2009 by Wiley Periodicals, Inc.

    The lack of objective disease markers is a major cause of misdiagnosis and nonstandardized approaches in delirium. Recent studies conducted in well-selected patients and confined study environments suggest that quantitative electroencephalography (qEEG) can provide such markers. We hypothesize that qEEG helps remedy diagnostic uncertainty not only in well-defined study cohorts but also in a heterogeneous hospital population. In this retrospective case-control study, EEG power spectra of delirious patients and age-/gender-matched controls (n = 31 and n = 345, respectively) were fitted in a linear model to test their performance as binary classifiers. We subsequently evaluated the diagnostic performance of the best classifiers in control samples with normal EEGs (n = 534) and real-world samples including pathologic findings (n = 4294). Test reliability was estimated through split-half analyses. We found that the combination of spectral power at F3-P4 at 2 Hz (area under the curve [AUC] = .994) and C3-O1 at 19 Hz (AUC = .993) provided a sensitivity of 100% and a specificity of 99% to identify delirious patients among normal controls. These classifiers also yielded a false positive rate as low as 5% and increased the pretest probability of being delirious by 57% in an unselected real-world sample. Split-half reliabilities were .98 and .99, respectively. This retrospective study yielded preliminary evidence that qEEG provides excellent diagnostic performance to identify delirious patients even outside confined study environments. It furthermore revealed reduced beta power as a novel specific finding in delirium and that a normal EEG excludes delirium. Prospective studies including parameters of pretest probability and delirium severity are required to elaborate on these promising findings.

    To determine predisposing and precipitating risk factors for incident delirium in medical patients during an acute hospital admission. Incident delirium is the most common complication of hospital admission for older patients. Up to 30% of hospitalised medical patients experience incident delirium. Determining risk factors for delirium is important for identifying patients who are most susceptible to incident delirium. Retrospective case-control study with two controls per case. An audit tool was used to review medical records of patients admitted to acute medical units for data regarding potential risk factors for delirium. Data were collected between August 2013 and March 2014 at three hospital sites of a healthcare organisation in Melbourne, Australia. Cases were 161 patients admitted to an acute medical ward and diagnosed with incident delirium between 1 January 2012 and 31 December 2013. Controls were 321 patients sampled from the acute medical population admitted within the same time range, stratified for admission location and who did not develop incident delirium during hospitalisation. Identified using logistic regression modelling, predisposing risk factors for incident delirium were dementia, cognitive impairment, functional impairment, previous delirium and fracture on admission. Precipitating risk factors for incident delirium were use of an indwelling catheter, adding more than three medications during admission and having an abnormal sodium level during admission. Multiple risk factors for incident delirium exist; patients with a history of delirium, dementia and cognitive impairment are at greatest risk of developing delirium during hospitalisation. Nurses and other healthcare professionals should be aware of patients who have one or more risk factors for incident delirium. Knowledge of risk factors for delirium has the potential to increase the recognition and understanding of patients who are vulnerable to delirium. Early recognition and

    The aim was to describe sickness allowance histories before disability retirement due to mental disorders and to examine whether receiving sickness allowance due to mental disorders and somatic conditions predicts future disability retirement. Pre-retirement sickness allowance histories were traced backwards for 7 years among Finnish residents aged 25-64 years who had retired due to mental disorders in 2011 (n=5.544). For each retiree, five sex- and age-matched controls were drawn from the non-retired population. Conditional logistic regression was used to calculate the risk for disability retirement by sickness allowance history and to control for the effects of educational level, social class, marital status and the urbanisation level of the municipality. The proportion of sickness allowance recipients increased steadily during the years preceding disability retirement, and was highest among those who retired due to bipolar disorders or depression. Those who had received sickness allowance due to mental disorders 6-7 years earlier had 6.5 times higher risk and those with sickness allowance 1-2 years earlier 11.7 times higher risk for disability retirement. Sickness allowance due to somatic conditions increased the risk for disability retirement 1.6-1.9 times. Sickness allowance most strongly predicted retirement due to bipolar disorders and depression. Adjustment for covariates had little effect. Those who retired due to mental disorders more often had sickness allowance due to both mental disorders and somatic conditions, but in particular sickness allowance due to mental disorders predicted disability retirement due to mental disorders. © 2015 the Nordic Societies of Public Health.

    Monoamine oxidase type B (MAO-B) inhibitors, such as selegiline and rasagiline, can be used as monotherapy or adjuvant therapy to levodopa in Parkinson's disease (PD). Data on long-term efficacy of MAO-B inhibitors are limited with no head-to-head comparison available to date. The aim of this case-control retrospective study was to analyze data from patients with PD attending the Parkinson Institute (Milan, Italy) over a 6-year period (2009-2015) and compare the effects of selegiline and rasagiline on levodopa treatment outcomes. Patients with PD treated with either selegiline (n = 85) or rasagiline (n = 85) for 3 years as well as a control group of patients (N = 170) who have never received MAO-B inhibitors, were matched for gender, disease duration (±1 year) and age (±1 year) at baseline assessment (ratio 1:1:2). The Unified PD Rating Scale and the Hoehn-Yahr staging system were used for clinical comparisons. At baseline, mean PD duration was 6.5 years and clinical features were comparable across all three groups. After a mean follow-up of approximately 37 months, no differences in clinical progression of motor and non-motor symptoms were observed between the three groups. However, MAO-B inhibitor use was associated with ~2-fold lower change in daily dose of levodopa (p rasagiline. Long-term use of MAO-B inhibitors resulted in a significant reduction in levodopa requirements and a lower frequency of dyskinesias in patients with PD. Selegiline and rasagiline had equal efficacy in controlling motor symptoms in PD patients on optimized therapy.

    Full Text Available Abstract Background Admitted patients who fall and injure themselves during an acute hospitalization incur increased costs, morbidity, and mortality, but little research has been conducted on identifying inpatients at high risk to injure themselves in a fall. Falls risk assessment tools have been unsuccessful due to their low positive predictive value when applied broadly to entire hospital populations. We aimed to identify variables associated with the risk of or protection against injurious fall in the inpatient setting. We also aimed to test the variables in the ABCs mnemonic (Age > 85, Bones-orthopedic conditions, anti-Coagulation and recent surgery for correlation with injurious fall. Methods We performed a retrospective case-control study at an academic tertiary care center comparing admitted patients with injurious fall to admitted patients without fall. We collected data on the demographics, medical and fall history, outcomes, and discharge disposition of injured fallers and control patients. We performed multivariate analysis of potential risk factors for injurious fall with logistic regression to calculate adjusted odds ratios. Results We identified 117 injured fallers and 320 controls. There were no differences in age, anti-coagulation use or fragility fractures between cases and controls. In multivariate analysis, recent surgery (OR 0.46, p = 0.003 was protective; joint replacement (OR 5.58, P = 0.002, psychotropic agents (OR 2.23, p = 0.001, the male sex (OR 2.08, p = 0.003 and history of fall (OR 2.08, p = 0.02 were significantly associated with injurious fall. Conclusion In this study, the variables in the ABCs parameters were among the variables not useful for identifying inpatients at risk of injuring themselves in a fall, while other non-ABCs variables demonstrated a significant association with injurious fall. Recent surgery was a protective factor, and practices around the care of surgical patients could be

    Concerns about the high cost of orphan drugs has led to questions being asked about the generosity of the incentives for development, and associated company profits. We conducted a retrospective, propensity score matched study of publicly-listed orphan companies. Cases were defined as holders of orphan drug market authorisation in Europe or the USA between 2000-12. Control companies were selected based on their propensity for being orphan drug market authorisation holders. We applied system General Method of Moments to test whether companies with orphan drug market authorization are valued higher, as measured by the Tobin's Q and market to book value ratios, and are more profitable based on return on assets, than non-orphan drug companies. 86 companies with orphan drug approvals in European (4), USA (61) or both (21) markets were matched with 258 controls. Following adjustment, orphan drug market authorization holders have a 9.6% (95% confidence interval, 0.6% to 18.7%) higher return on assets than non-orphan drug companies; Tobin's Q was higher by 9.9% (1.0% to 19.7%); market to book value by 15.7% (3.1% to 30.0%) and operating profit by 516% (CI 19.8% to 1011%). For each additional orphan drug sold, return on assets increased by 11.1% (0.6% to 21.3%), Tobin's Q by 2.7% (0.2% to 5.2%), and market to book value ratio by 5.8% (0.7% to 10.9%). Publicly listed pharmaceutical companies that are orphan drug market authorization holders are associated with higher market value and greater profits than companies not producing treatments for rare diseases.

    Peritonitis, which is one of the leading complications of peritoneal dialysis (PD) worldwide, severely affected morbidity and mortality of the PD patients. Although many efforts have been made to prevent PD-related peritonitis, it seems impossible to prevent it completely. Many causes have been reported to lead to peritonitis, and contamination during bag exchange is one of the important risk factors for peritonitis. Here, we introduce an operating vehicle, which we invented to provide a sterile and safe space for bag exchange. A single-center, retrospective, case-control study was undertaken to determine whether this operating vehicle has a protective role in preventing peritonitis. In total, 462 continuous ambulatory peritoneal dialysis patients were included in this study from October 2014 to March 2017. According to their personal will, these patients chose to use operating vehicle or traditional method during their bag exchange. The demographic, clinical and laboratory data of these patients in the two groups were collected, analyzed and compared. Of 462 patients with home dialysis, operating vehicle group consisted of 61 patients, and control group consisted of 401 patients. In the control group, over 677 patient-years, peritonitis occurred in 69 of 401 patients (17.2%), while in the operating vehicle group, over 60 patient-years, only 4 of 61 patients (6.6%) had episodes of peritonitis. The number of patients suffered from peritonitis was significantly decreased in the operating vehicle group (P = 0.034). Besides, there were a total of 99 episodes of peritonitis, and the rate was 1 episode every 7.2 patient-years in control group and 1 episode every 12 patient-years in the operating vehicle group. There was significant difference between the two groups (0.013). Positive dialysate cultures were obtained in majority of the peritonitis episodes (60.6%). Operating vehicle might help to reduce PD-related peritonitis by preventing contamination during bag

    This work aims to test the hypothesis that the funniest comedians are most at risk of a premature death and reduced longevity compared to their relatively less funny counterparts. A retrospective longitudinal cohort study with a nested case-control analysis of longevity of 53 male British comedians born between 1900 and 1954 was conducted. All comedians were given a subjective score from 1 (relatively funny) to 10 (hilariously funny) by the study investigators. The survival profile of all comedians was then examined adjusting for decade of birth, whether they worked in a comedy team and their comedy score. A nested case-control analysis examined the longevity of those comedians working in teams according to their pre-specified status within the team (straight/less funny versus funny team member). On an adjusted basis, there was no correlation between the decade of birth (HR 0.94, 95% 0.65 to 1.38 per incremental decade; p=0.763) and comedy team status (HR 1.13, 95% 0.51 to 2.48 versus independent comedian; p=0.761) with longevity. However, an increasingly funny comedy score was associated with increased mortality (HR 1.24, 95% CI 1.06 to 1.44 per unit funny score; p=0.006). Of the 23 comedians adjudged to be very funny (score 8-10), 18 (78%) had died versus 12 (40%) of the rest; mean age at death 63.3±12.2 versus 72.3±14.7 (p=0.079). Within comedy teams, those identified as the funnier member(s) of the partnership were, on an adjusted basis, more than three times more likely to die prematurely when compared to their more serious comedy partners (HR 3.52, 95% CI 1.22, 10.1; p=0.020). These data suggest that elite comedians are at increased risk of premature death compared to their less funny counterparts. Mental health issues and personality characteristics that help shape their comedic talent and success may well explain their reduced longevity and raises serious issues for identifying and mitigating their risk of a premature death.

    To evaluate if preoperative radiotherapy influences course of operation (radical hysterectomy and lymphadenectomy) and postoperative period in series of stage IB-IIA cervical carcinomas. Retrospective comparative study was performed. During the study we analyzed 101 case histories of patients who underwent radical type II hysterectomy with lymphadenectomy in Kaunas University of Medicine Hospital and Kaunas Hospital of Oncology between 1995 and 2002. Mean operation time was shorter, hemoglobin and hematocrit values after operation were better, stay in hospital was longer, demand for narcotic analgetics was bigger, function of ovaries was maintained more rarely (p 0.05). In our study, preoperative radiotherapy did not seem to complicate course of radical hysterectomy. (author)

    Both obesity and diabetes mellitus are well-known risk factors for tendinopathies. We retrospectively compared the efficacy of single corticosteroid injections in treating lateral epicondylitis in patients with and without metabolic syndrome (MetS). Fifty-one patients with lateral epicondylitis and MetS were age- and sex-matched with 51 controls without MetS. Pain severity, Disability of the Arm, Shoulder, and Hand score, and grip strength were assessed at base line and at 6, 12 and 24 weeks post-injection. The pain scores in the MetS group were greater than those in the control group at 6 and 12 weeks. The disability scores and grip strength in the MetS group were significantly worse than those of the control group at 6 weeks. However, there were no significant differences at 24 weeks between the groups in terms of pain, disability scores and grip strengths. After 24 weeks, three patients (6%) in the control group and five patients (10%) in the MetS group had surgical decompression (p = 0.46). Patients with MetS are at risk for poor functional outcome after corticosteroid injection for lateral epicondylitis in the short term, but in the long term there was no difference in outcomes of steroid injection in patients with and without MetS.

    Some old persons at risk do develop, but others, at comparable risk, do not develop high-grade pressure sores. To evaluate potentially different risk factors, we performed a post mortem case-control study in old persons who developed high-grade pressure sores within six months until 14 days before death. Consecutive cases with pressure sores grade >/=3 and potential controls at comparably high risk for pressure sores were examined before cremation. After written informed consent had been obtained by the next relatives, all available nursing and medical records of the deceased were thoroughly evaluated. Cases and controls were matched according to age, gender, immobility, and cachexia.A total of 100 cases with 71 pressure sores grade 3 and 29 pressure sores grade 4 were compared to 100 controls with 27 pressure sores grade pressure sores in frail older high-risk persons. Sedative drug effects and impaired patient compliance with preventive and therapeutic measures may also be associated with the development of high-grade pressure sores in old persons at high risk.

    Evidence suggests that individuals with Alzheimer's disease (AD) are often diagnosed in the later stages of their disease with a poor prognosis. This study aimed to identify patterns in signs and symptoms preceding the clinical diagnosis of AD to suggest a predictive model for earlier diagnosis of the disease in the primary care. A retrospective medical record review; nested case control design. Participants included one hundred and nine patients from three general practice (GP) surgeries in Milton Keynes and Luton Clinical Commissioning groups (CCG) (37 cases with AD and 72 controls without AD). A retrospective analysis using the logistic regression of the presence of signs and symptoms before the diagnosis of AD was attained. Identification of the timing and sequence of appearance of these presentations as first reported before the clinical diagnosis was measured. Episodic memory with an odds ratio of 1.85 was the most frequent presentation, documented in 1.38% of the controls and 75.6% in cases. Auditory disturbance with an odds ratio of 3.03, which has not previously been noted except in the form of auditory hallucination, could have a diagnostic value. Auditory disturbance, which occurred mostly in the Caucasian females, could discriminate individuals with AD from those without. The symptom, which presented up to 14.5 (mean time) years prior to clinical diagnosis, was identified in Caucasians and mixed race individuals only.

    The purpose of this study was to evaluate acute and late toxicities of radiotherapy for patients with discoid lupus erythematosus (DLE). A retrospective review was performed of patients with DLE who received radiotherapy at our institution between 1980 and 2005. Patients with other connective tissue disorders were excluded. Control patients were matched 2:1 with the DLE treatment courses based on age, cancer diagnosis, year of treatment, radiotherapy dose, and sex. Acute (within 30 days from the completion of radiotherapy) and late toxicities were evaluated for each treatment course using the Common Terminology Criteria for Adverse Events Version 3.0. Twelve patients with DLE received a total of 15 radiotherapy courses. The median follow-up time was 2.6 years (range, 0.0-15.2 years). Acute toxicity of any organ was observed in 10 (67%) treatment courses, of which 2 (13%) were Grade 3 or higher. Acute Grade 1 or 2 dermatologic toxicity was observed in 8 courses (53%). Late toxicity of any organ was observed in 7 of 12 (58%) evaluable treatment courses, of which 3 (23%) were grade 3 or higher. Late grade 1 or 2 dermatologic toxicity was observed in 5 (42%) courses. No patient experienced acute or late Grade 3 or higher dermatologic toxicity. The rates of any organ or dermatologic acute and late toxicity were not significantly different between DLE and control treatment courses. Our findings do not suggest an increased risk of toxicity to the skin or other organs in patients with DLE receiving radiotherapy

    We estimate the effectiveness of Japanese encephalitis (JE) SA 14-14-2 live-attenuated vaccination single dose campaign among children aged 1-15 years in India during 2006-07. Acute encephalitis syndrome (AES) cases hospitalized following vaccination campaigns during the years 2006-08 were investigated retrospectively. The laboratory-confirmed JE cases were detected from the surveillance laboratories based on anti-JE IgM antibody by ELISA or viral RNA detection by RT-PCR in sera or cerebrospinal fluid. Consent was sought from parents or guardians. Four community controls were chosen randomly per case during house-to-house survey employing individual matching on age, gender and residence during the risk period. Vaccination history was enquired from the child's guardian and verified from vaccination card at home or records at health centre. Conditional logistic regression was conducted on matched case-control sets. We studied 149 cases and matched 596 controls. Vaccination effectiveness was 43.8% (95% CI, 1.9-67.8) based on vaccination card or record. However, effectiveness was 72.2% (95% CI, 56.2-82.4) based on parental history or card/record. Vaccination effectiveness in Assam state was higher than in Uttar Pradesh state. We concluded that the single subcutaneous dose of SA 14-14-2 JE vaccine provided moderate effectiveness in Indian children. Copyright © 2018 The Authors. Published by Elsevier Ltd..

    Vertex sharp transients (VSTs) of sleep often lateralize to the left or right frontocentral regions and can be mistaken as epileptiform. The aim of this study was to determine the prevalence of completely lateralized VSTs in pediatric-aged individuals and to assess their significance by comparing cohorts with and without epilepsy. The authors hypothesized that completely lateralized VSTs are normal and occur with similar frequencies in patients with and without epilepsy. The authors conducted a retrospective, blinded, case-control study comparing completely lateralized VSTs within a 5-minute EEG sleep epoch between cohorts of 100 patients with epilepsy and 100 age- and gender-matched controls. The number of patients with completely lateralized VSTs was not significantly different between cases (62%) and controls (65%) (P = 0.66). The median number of completely lateralized VSTs was small but not significantly different between cases (median 3) and controls (median 4) (P = 0.11). The presence of completely lateralized VSTs in cases (generalized vs. focal epilepsy) was not significantly different (P > 0.95). This is the first systematic study of the prevalence and significance of completely lateralized VSTs of sleep. This study provides class III evidence that completely lateralized VSTs, occurring in a sporadic fashion, are a normal phenomenon and should not be confused with epileptiform discharges.

    The goal of this study was to examine the association between IQ and suicide in psychiatric patients. We conducted a nested case-control study using data obtained from psychiatric patients affiliated with a general hospital in Seoul, Korea. In a one-to-two ratio the psychiatric patients who died of suicide (Suicide Group; n=35) were matched to those who didn't (Non-suicide Group; n=70) by age, gender, psychiatric diagnosis and approximate time of first treatment. IQ was measured using the Korean version of the Wechsler Adult Intelligence Scale-Revised. There were no significant differences in any type of IQ between suicide patients and non-suicide patients. Logistic regression showed no evidence of an association between IQ and suicide. These results do not support the existence of an association between IQ and suicide.

    Whole-cell pertussis (wP) and measles vaccines are effective in preventing disease but have also been suspected of increasing the risk of encephalopathy or encephalitis. Although many countries now use acellular pertussis vaccines, wP vaccine is still widely used in the developing world. It is therefore important to evaluate whether wP vaccine increases the risk of neurologic disorders. A retrospective case-control study was performed at 4 health maintenance organizations. Records from January 1, 1981, through December 31, 1995, were examined to identify children aged 0 to 6 years old hospitalized with encephalopathy or related conditions. The cause of the encephalopathy was categorized as known, unknown or suspected but unconfirmed. Up to 3 controls were matched to each case. Conditional logistic regression was used to analyze the relative risk of encephalopathy after vaccination with diphtheria-tetanus-pertussis (DTP) or measles-mumps-rubella (MMR) vaccines in the 90 days before disease onset as defined by chart review compared with an equivalent period among controls indexed by matching on case onset date. Four-hundred fifty-two cases were identified. Cases were no more likely than controls to have received either vaccine during the 90 days before disease onset. When encephalopathies of known etiology were excluded, the odds ratio for case children having received DTP within 7 days before onset of disease was 1.22 (95% confidence interval [CI] = 0.45-3.31, P = 0.693) compared with control children. For MMR in the 90 days before onset of encephalopathy, the odds ratio was 1.23 (95% confidence interval = 0.51-2.98, P = 0.647). In this study of more than 2 million children, DTP and MMR vaccines were not associated with an increased risk of encephalopathy after vaccination.

    Alcohol is an important determinant of the high and fluctuating adult mortality rates in Russia, but cause-specific detail is lacking. Our case-control study investigated the effects of alcohol consumption on male and female cause-specific mortality. In three Russian industrial cities with typical 1990s mortality patterns (Tomsk, Barnaul, Biysk), the addresses of 60,416 residents who had died at ages 15-74 years in 1990-2001 were visited in 2001-05. Family members were present for 50,066 decedents; for 48,557 (97%), the family gave proxy information on the decedents' past alcohol use and on potentially confounding factors. Cases (n=43,082) were those certified as dying from causes we judged beforehand might be substantially affected by alcohol or tobacco; controls were the other 5475 decedents. Case versus control relative risks (RRs; calculated as odds ratios by confounder-adjusted logistic regression) were calculated in ever-drinkers, defining the reference category by two criteria: usual weekly consumption always less than 0.5 half-litre bottles of vodka (or equivalent in total alcohol content) and maximum consumption of spirits in 1 day always less than 0.5 half-litre bottles. Other ever-drinkers were classified by usual weekly consumption into three categories: less than one, one to less than three, and three or more (mean 5.4 [SD 1.4]) bottles of vodka or equivalent. In men, the three causes accounting for the most alcohol-associated deaths were accidents and violence (RR 5.94, 95% CI 5.35-6.59, in the highest consumption category), alcohol poisoning (21.68, 17.94-26.20), and acute ischaemic heart disease other than myocardial infarction (3.04, 2.73-3.39), which includes some misclassified alcohol poisoning. There were significant excesses of upper aerodigestive tract cancer (3.48, 2.84-4.27) and liver cancer (2.11, 1.64-2.70). Another five disease groups had RRs of more than 3.00 in the highest alcohol category: tuberculosis (4.14, 3.44-4.98), pneumonia (3

    Full Text Available Lingual nerve injury or neuropraxia is a rare but potentially serious perioperative complication following airway instrumentation during general anesthesia. This study explored the the incidence and perioperative risk factors for lingual nerve injury in patients receiving laryngeal mask (LMA or endotracheal (ETGA general anesthesia in a single center experience.All surgical patients in our hospital who received LMA or ETGA from 2009 to 2013 were included, and potential perioperative risk factors were compared. Matched controls were randomly selected (in 1:5 ratio from the same database in non-case patients. A total of 36 patients in the records had reported experiencing tongue numbness after anesthesia in this study. Compared with the non-case surgical population (n = 54314, patients with tongue numbness were significantly younger (52.2±19.5 vs 42.0±14.5; P = 0.002 and reported lower ASA physical statuses (2.3±0.7 vs 1.6±0.6; P<0.001. Patient gender, anesthesia technique used, and airway device type (LMA or ETGA did not differ significantly across the two groups. A significantly higher proportion of patients underwent operations of the head-and-neck region (38.9 vs 15.6%; P = 0.002 developed tongue numbness after anesthesia. Multivariate logistic regression analysis indicated that head-and-neck operations remained the most significant independent risk factor for postoperative lingual nerve injury (AOR 7.63; 95% CI 2.03-28.70.The overall incidence rate of postoperative lingual neuropraxy was 0.066% in patients receiving general anesthesia with airway device in place. Young and generally healthy patients receiving head-and-neck operation are at higher risk in developing postoperative lingual neuropraxy. Attention should be particularly exercised to reduce the pressure of endotracheal tube or laryngeal mask on the tongue during head-and-neck operation to avert the occurrence of postoperative lingual neuropraxy.

    Full Text Available Breast cancer is recognized as a major public health problem in developing countries; however, there is very little evidence of behavioral factors associated with breast cancer risk. This study was conducted to identify lifestyles as risk factors for breast cancer among Central African women. A case-control study was conducted with 174 cases confirmed histologically by the pathology unit of the National Laboratory and 348 age-matched controls. Data collection tools included a questionnaire with interviews and medical records of patients. Data were analyzed using SPSS software version 20. Odd ratio (OR and 95% confidence intervals (95% CI were obtained by unconditional logistic regression. In total, 522 women were studied with a mean age of 45.8 (SD = 13.4 years. By unconditional logistic regression model, women with breast cancer were more likely to have attained illiterate and elementary education level [11.23 (95% CI, 4.65-27.14 and 2.40 (95% CI, 1.15-4.99], married [2.09 (95% CI, 1.18-3.71], positive family history [2.31 (95% CI, 1.36-3.91], radiation exposure [8.21 (95% CI, 5.04-13.38], consumption charcuterie [10.82 (95% CI, 2.39-48.90], fresh fish consumption [4.26 (95% CI, 1.56-11.65], groundnut consumption [6.46 (95% CI, 2.57-16.27], soybean consumption [16.74 (95% CI, 8.03-39.84], alcohol [2.53 (95% CI, 1.39-4.60], habit of keeping money in bras[3.57 (95% CI, 2.24-5.69], overweight [5.36 (95% CI, 4.46-24.57] and obesity [3.11(95% CI, 2.39-20.42]. However, decreased risk of breast cancer was associated with being employed [0.32 (95% CI, 0.19-0.56], urban residence [0.16 (95% CI, 0.07-0.37], groundnut oil consumption [0.05 (95% CI, 0.02-0.14], wine consumption [0.16 (95% CI, 0.09-0.26], non habit of keeping cell phone in bras [0.56 (95% CI, 0.35-0.89] and physical activity [0.71(95% CI, 0.14-0.84].

    Penicillin-susceptible Staphylococcus aureus isolates account for a fifth of cases of S. aureus bacteraemia (SAB) in Denmark, but little is known about treatment outcomes with penicillins or other antimicrobials. Here we compare penicillin, dicloxacillin and cefuroxime as definitive treatments in relation to 30 day mortality. A retrospective chart review of 588 penicillin-susceptible S. aureus cases at five centres from January 1995 to December 2010. Data on demographics, antimicrobial treatment, clinical signs and symptoms, and mortality at day 30 were collected. Hazard ratios (HRs) with 95% CIs associated with mortality were modelled using propensity-score-adjusted Cox proportional hazards regression analysis. Propensity-score-matched case-control studies were carried out. Definitive therapy with cefuroxime was associated with an increased risk of 30 day mortality compared with penicillin (adjusted HR 2.54, 95% CI 1.49-4.32). Other variables that were statistically significantly associated with 30 day mortality included increasing age, disease severity and a primary respiratory focus. Osteomyelitis/arthritis was associated with a lower risk of death than were other secondary manifestations. Propensity-score-matched case-control studies confirmed an increased risk of 30 day mortality: cefuroxime treatment (39%) versus penicillin treatment (20%), P = 0.037; and cefuroxime treatment (38%) versus dicloxacillin treatment (10%), P = 0.004. Definitive therapy for penicillin-susceptible SAB with cefuroxime was associated with a significantly higher mortality than was seen with therapy with penicillin or dicloxacillin.

    Time to source control plays a determinant prognostic role in patients having severe intra-abdominal infections (IAIs). Open abdomen (OA) management became an effective treatment option for peritonitis. Aim of this study was to analyze the correlation between time to source control and outcome in patients presenting with abdominal sepsis and treated by OA. We retrospectively analyzed 111 patients affected by abdominal sepsis and treated with OA from May 2007 to May 2015. Patients were classified according to time interval from first patient evaluation to source control. The end points were intra-hospital mortality and primary fascial closure rate. The in-hospital mortality rate was 21.6% (24/111), and the primary fascial closure rate was 90.9% (101/111). A time to source control ≥6 h resulted significantly associated with a poor prognosis and a lower fascial closure rate (mortality 27.0 vs 9.0%, p = 0.04; primary fascial closure 86 vs 100%, p = 0.02). We observed a direct increase in mortality (and a reduction in closure rate) for each 6-h delay in surgery to source control. Early source control using OA management significantly improves outcome of patients with severe IAIs. This damage control approach well fits to the treatment of time-related conditions, particularly in case of critically ill patients.

    Patients with voltage-gated potassium channel (VGKC)-complex antibodies are increasingly recognized as having central, peripheral or combined phenotypes. With increasing awareness, more patients are tested and the clinical spectrum is expanding. Consequently, clinicians may be uncertain as to which patients should or should not be tested. Previous studies have identified common clinical features, but none has looked at the usefulness of these in predicting seropositive disease. We conducted a case-control study of patients tested for VGKC-complex antibodies over 10years at a regional tertiary neurology centre determining which clinical/biochemical features were associated with antibody-positive disease. We found a marked increase in the numbers tested, although the percentage positive remained low. Antibody titre was highest in central disease (pVGKC-disease (p=0.01). Seizures were present in 11 (69%) of those with VGKC-disease versus three (18%) without (odds ratio [OR] 10.3, 95% confidence interval [CI]: 2.0-52.7, p=0.005). There was an inverse correlation between the antibody titre and serum sodium. A multivariate model selected seizures and hyponatraemia as predictive of VGKC disease (sensitivity 75% and specificity 82%); faciobrachial dystonic movements were specific but insensitive. Interestingly serum alkaline phosphatase was higher in those with VGKC-disease (p=0.016) and highest in those with peripheral disease (p=0.015). An ALP>70u/L was strongly associated with antibody positivity (OR 4.11 95% CI: 1.43-11.8, p=0.007) with a sensitivity of 74.2%. The presence of seizures, faciobrachial movements, and hyponatraemia should raise suspicion of VGKC-disease; alkaline phosphatase may represent a novel biomarker, particularly in those with peripheral disease.

    Pituitary gigantism (PG) is a rare pediatric disease with poorly defined long-term outcomes. Our aim is to describe the longitudinal clinical course in PG patients using a single-center, retrospective cohort study. Patients younger than 19 years diagnosed with PG were identified. Thirteen cases were confirmed based on histopathology of a GH secreting adenoma or hyperplasia and a height >2 SD for age and gender. Laboratory studies, initial pathology, and imaging were abstracted. Average age at diagnosis was 13 years with an average initial tumor size of 7.4×3.8 mm. Initial transsphenoidal surgery was curative in 3/12 patients. Four of the nine patients who failed the initial surgery required a repeat procedure. Octreotide successfully normalized GH levels in 1/6 patients with disease refractory to surgery (1/6). Two out of five patients received pegvisomant after failing octreotide but only one patient responded to treatment. Five patients were ultimately treated with radiosurgery or radiation patients were followed for an average of 10 years. PG is difficult to treat. In most patients, the initial transsphenoidal surgery failed to normalize GH levels. If the initial surgery was unsuccessful, repeat surgery was unlikely to control GH secretion. Treatment with octreotide or pegvisomant was successful in less than half the patients failing surgery. Radiosurgery was curative, but is not an optimal treatment for pediatric patients. Despite the small sample, our study suggests that the treatment outcome of pediatric PG may be different than adults.

    Gonorrhoea is a major global public health problem that is exacerbated by drug resistance. Effective vaccine development has been unsuccessful, but surveillance data suggest that outer membrane vesicle meningococcal group B vaccines affect the incidence of gonorrhoea. We assessed vaccine effectiveness of the outer membrane vesicle meningococcal B vaccine (MeNZB) against gonorrhoea in young adults aged 15-30 years in New Zealand. We did a retrospective case-control study of patients at sexual health clinics aged 15-30 years who were born between Jan 1, 1984, and Dec 31, 1998, eligible to receive MeNZB, and diagnosed with gonorrhoea or chlamydia, or both. Demographic data, sexual health clinic data, and National Immunisation Register data were linked via patients' unique personal identifier. For primary analysis, cases were confirmed by laboratory isolation or detection of Neisseria gonorrhoeae only from a clinical specimen, and controls were individuals with a positive chlamydia test only. We estimated odds ratios (ORs) comparing disease outcomes in vaccinated versus unvaccinated participants via multivariable logistic regression. Vaccine effectiveness was calculated as 100×(1-OR). 11 of 24 clinics nationally provided records. There were 14 730 cases and controls for analyses: 1241 incidences of gonorrhoea, 12 487 incidences of chlamydia, and 1002 incidences of co-infection. Vaccinated individuals were significantly less likely to be cases than controls (511 [41%] vs 6424 [51%]; adjusted OR 0·69 [95% CI 0·61-0·79]; pvaccine effectiveness of MeNZB against gonorrhoea after adjustment for ethnicity, deprivation, geographical area, and sex was 31% (95% CI 21-39). Exposure to MeNZB was associated with reduced rates of gonorrhoea diagnosis, the first time a vaccine has shown any protection against gonorrhoea. These results provide a proof of principle that can inform prospective vaccine development not only for gonorrhoea but also for meningococcal vaccines. GSK

    Although adrenaline (epinephrine) is a cornerstone of initial anaphylaxis treatment, it is not often used. We sought to assess whether use of adrenaline in hemodynamically stable patients with anaphylaxis could prevent the development of hypotension. We conducted a retrospective cohort study of 761 adult patients with anaphylaxis presenting to the emergency department (ED) of a tertiary care hospital over a 10-year period. We divided the patients into two groups according to the occurrence of hypotension and compared demographic characteristics, clinical features, treatments and outcomes. Of the 340 patients with anaphylaxis who were normotensive at first presentation, 40 patients experienced hypotension during their ED stay. The ED stay of the hypotension group was significantly longer than that of patients who did not experience hypotension (496 min vs 253 min, P = 0.000). Adrenaline use in hemodynamically stable anaphylaxis patient was independently associated with a lower risk of developing in-hospital occurrence of hypotension: OR, 0.254 [95% CI, 0.091-0.706]. Adrenaline use in hemodynamically stable anaphylaxis patients was associated with a reduced risk of developing in-hospital occurrence of hypotension. Adverse events induced by adrenaline were rare when the intramuscular route was used.

    Studies associate pandemic influenza vaccination with narcolepsy. In Germany, a retrospective, multicenter, matched case-control study was performed to identify risk factors for narcolepsy, particularly regarding vaccinations (seasonal and pandemic influenza vaccination) and infections (seasonal and pandemic influenza) and to quantify the detected risks. Patients with excessive daytime sleepiness who had been referred to a sleep center between April 2009 and December 2012 for multiple sleep latency test (MSLT) were eligible. Case report forms were validated according to the criteria for narcolepsy defined by the Brighton Collaboration (BC). Confirmed cases of narcolepsy (BC level of diagnostic certainty 1-4a) were matched with population-based controls by year of birth, gender, and place of residence. A second control group was established including patients in whom narcolepsy was definitely excluded (test-negative controls). A total of 103 validated cases of narcolepsy were matched with 264 population-based controls. The second control group included 29 test-negative controls. A significantly increased odd ratio (OR) to develop narcolepsy (crude OR [cOR] = 3.9, 95% confidence interval [CI] = 1.8-8.5; adjusted OR [aOR] = 4.5, 95% CI = 2.0-9.9) was detected in individuals immunized with pandemic influenza A/H1N1/v vaccine prior to symptoms onset as compared to nonvaccinated individuals. Using test-negative controls, in individuals immunized with pandemic influenza A/H1N1/v vaccine prior to symptoms onset, a nonsignificantly increased OR of narcolepsy was detected when compared to nonvaccinated individuals (whole study population, BC levels 1-4a: cOR = 1.9, 95% CI = 0.5-6.9; aOR = 1.8, 95% CI = 0.3-10.1). The findings of this study support an increased risk for narcolepsy after immunization with pandemic influenza A/H1N1/v vaccine. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Risk stratification of the early repolarization pattern (ERP is needed to identify malignant early repolarization. J-point elevation with a horizontal ST segment was recently suggested as a malignant feature of the ERP. In this study, the prevalence of the ERP with a horizontal ST segment was examined among survivors of sudden cardiac arrest (SCA without structural heart disease to evaluate the value of ST-segment morphology in risk stratification of the ERP. Methods We reviewed the data of 83 survivors of SCA who were admitted from August 2005 to August 2010. Among them, 25 subjects without structural heart disease were included. The control group comprised 60 healthy subjects who visited our health promotion center; all control subjects were matched for age, sex, and underlying disease (diabetes mellitus, hypertension. Early repolarization was defined as an elevation of the J point of at least 0.1 mV above the baseline in at least two continuous inferior or lateral leads that manifested as QRS slurring or notching. An ST-segment pattern of Results The SCA group included 17 men (64% with a mean age of 49.7 ± 14.5 years. The corrected QTc was not significantly different between the SCA and control groups (432.7 ± 37.96 vs. 420.4 ± 26.3, respectively; p = 0.089. The prevalence of ERP was not statistically different between the SCA and control groups (5/25, 20% vs. 4/60, 6.7%, respectively; p = 0.116. The prevalence of early repolarization with a horizontal ST segment was more frequent in the SCA than in the control group (20% vs. 3.3%, respectively; p = 0.021. Four SCA subjects (16% and one control subject (1.7% had a J-point elevation of >2 mm (p = 0.025. Four SCA subjects (16% and one (1.7% control subject had an ERP in the inferior lead (p = 0.025. Conclusion The prevalence of ERP with a horizontal ST segment was higher in patients with aborted SCA than in matched controls. This result suggests that ST morphology has

    All newborns are at risk of deterioration as a result of failing to make the transition to extra uterine life. Signs of deterioration can be subtle and easily missed. It has been postulated that the use of an Early Warning Tool may assist clinicians in recognising and responding to signs of deterioration earlier in neonates, thereby preventing a serious adverse event. To examine whether observations from a Standard Observation Tool, applied to three neonatal Early Warning Tools, would hypothetically trigger an escalation of care more frequently than actual escalation of care using the Standard Observation Tool. A retrospective case-control study. A maternity unit in a tertiary public hospital in Australia. Neonates born in 2013 of greater than or equal to 34(+0) weeks gestation, admitted directly to the maternity ward from their birthing location and whose subsequent deterioration required admission to the neonatal unit, were identified as cases from databases of the study hospital. Each case was matched with three controls, inborn during the same period and who did not experience deterioration and neonatal unit admission. Clinical and physiological data recorded on a Standard Observation Tool, from time of admission to the maternity ward, for cases and controls were charted onto each of three Early Warning Tools. The primary outcome was whether the tool 'triggered an escalation of care'. Descriptive statistics (n, %, Mean and SD) were employed. Cases (n=26) comprised late preterm, early term and post-term neonates and matched by gestational age group with 3 controls (n=78). Overall, the Standard Observation Tool triggered an escalation of care for 92.3% of cases compared to the Early Warning Tools; New South Wales Health 80.8%, United Kingdom Newborn Early Warning Chart 57.7% and The Australian Capital Territory Neonatal Early Warning Score 11.5%. Subgroup analysis by gestational age found differences between the tools in hypothetically triggering an escalation of

    Traditional environmental risk factors in inflammatory bowel disease (IBD), ulcerative colitis (UC) and Crohn's disease (CD), were examined as part of the retrospective epidemiologic study conducted in Vukovar-Srijem County, north-eastern Croatia in 2010. The geographical variations in the frequency of IBD in Croatia have been observed, which is also the trend in the Central Eastern European region and Europe as a whole, indicating the influence of environmental and lifestyle factors. However, the data on the spread of environmental IBD risk factors are still limited. The purpose of this study was to analyse the traditional environmental risk factors in IBD on our cohort sample, including measles virus infection and vaccination (MMR vaccine-Mumps, Measles, Rubella), tonsillectomy, appendectomy, current and former cigarette smoking and use of oral contraceptives in women. This retrospective, case-control study was performed as a part of a wider epidemiologic study aimed at assessing the incidence, prevalence and clinical expression of IBD, in Vukovar-Srijem County (population: 204,768; 2001), which is a lesser developed part of the continental Croatia that experienced deep demographic changes in the recent past. IBD patients were identified according to the hospital's patient records. There were 119 UC patients and 31 CD patients of a total of 150 patients in the cohort. A total of 150 individuals, volunteers, not having a diagnosis of IBD, age- and sex-matched, were used as the control group. Information on examined risk factors were obtained from all subjects in a previously conducted interview. Patients were contacted personally or by phone and interviewed by a gastroenterologist. There were no differences in the number of smokers, former smokers and non-smokers, between UC and CD patients and the controls, nor in the duration of smoking (years), in current smokers and ex-smokers. Only marginally significant longer time of non-smoking, in ex-smokers was found in

This was a retrospective, observational, case-control study conducted in Italy, based on administrative database analysis. The aim of this study was to evaluate differences in health care costs of preterm infants with and without early hospitalization for bronchiolitis. Patients and methods: Preterm infants born in the period between January 1, 2009 and December 31, 2010 and hospitalized for bronchiolitis in the first year of life were selected from the ARNO Observatory database and observed for the first 4 years of life. These preterm infants were compared (paired 1–3 with preterm infants who were not hospitalized for bronchiolitis in the first year of life and with similar characteristics. Only direct health care costs reimbursed by the Italian National Health Service were considered for this study (drugs, hospitalizations, and diagnostic/therapeutic procedures. Results: Of 40,823 newborns in the accrual period, 863 were preterm with no evidence of prophylaxis, and 22 preterm infants were hospitalized for bronchiolitis (cases and paired with 62 controls. Overall, cases had 74% higher average cost per infant in the first 4 years of life than controls (18,624€ versus 10,189€, respectively. The major cost drivers were hospitalizations, accounting for >90% in both the populations. The increase in total yearly health care cost between cases and controls remained substantial even in the fourth year of life for all cost items. A relevant increase in hospitalizations and drug consumption linked to respiratory tract diseases was noted in

    Bile duct injury after ablation of malignant liver tumors (MLTs) was not unusual and should be avoided. However, few studies have focused on evaluating the risk factors for intrahepatic bile duct injury. To evaluate the risk factors for intrahepatic bile duct injury after ablation of MLTs and to evaluate the minimum safe distance for ablating tumors abutting bile ducts. Sixty-five patients with intrahepatic bile duct injury after ablation of MLTs, and 65 controls were recruited. Risk factors for intrahepatic bile duct injury were analyzed. Tumor location was recorded as ≤5 mm (group A), 5-10 mm (group B), and >10 mm (group C) from the right/left main duct or segmental bile duct. Ascites history (P bile duct dilatation before ablation (P bile duct injury. Significant differences in the risk of intrahepatic bile duct injury were found between groups B and C (P = 0.000), but not between groups A and B (P = 0.751). Ascites history (P = 0.002) and tumor location (P Bile duct injury after ablation of MLTs was the result of local treatment-related factors combined with the patients' general condition. The minimum safe distance for ablation of tumor abutting a bile duct was 10 mm.

    Full Text Available Abstract Background Hormonal and enzymatic factors may render certain individuals more susceptible to orthodontically induced inflammatory root resorption (OIIRR. The objectives of this study are (1 to identify biochemical key markers in blood and saliva that may be correlated to the trend of extensive OIIRR and (2 to utilise these markers to predict a susceptible patient-receiving orthodontic treatment. Methods Nine patients (mean age 23 + 2.9 years who had moderate to severe OIIRR that assessed via orthopantomograms and met the inclusion criteria were classified as the root resorption group (RRG. Blood chemistry was evaluated using the collection of fasting blood and unstimulated saliva samples. Multiplex enzyme-linked immunosorbent assay (ELISA arrays were used to screen blood and saliva samples for human cytokines, chemokines and several key enzymes that may play a role in root resorption following orthodontic force application. Biochemical findings from 16 matching subjects were used as the control (CG for comparative measurements. Results Patients with moderate to severe OIIRR showed a significant increase in salivary cytokines including interleukin (IL 7, IL-10, IL-12p70 and interferon-gamma (IFN-γ level as well as a significant decrease in IL-4 level. Osteocalcin and procollagen type I N-terminal peptide (P1NP appeared to be the only blood factors that showed a significant difference, more in the CG than the RRG. Conclusions Saliva might be a more valuable way of measuring changes in cytokine expression than blood secondary to orthodontic treatment. Although the increased expression of pro-inflammatory and anti-inflammatory cytokines may be determinants in the development of moderate to severe OIIRR, cytokine expression may be affected by several potential inflammations in another part of the body. Future research could investigate the cause/effect relationship of different cytokines, in a larger group of patients and at different

    The purpose of the present study was to retrospectively evaluate the clinical findings and treatment results for impacted permanent teeth associated with odontomas. We retrospectively investigated 73 odontomas in 72 patients who visited Kyungpook National University Dental Hospital from April 2004 through November 2011. The study was performed using medical records, panoramic radiographs, and pathological reports. Data gathered included age, gender, location, chief complaints, effects on dentition, and treatment of odontoma and the impacted tooth associated with odontoma. Most compound odontomas (46.7%) were found in the second decade and complex odontomas were not related to age. Odontomas showed no gender predilection. Fifty-five cases (75.3%) of odontomas were detected on routine dental radiographs. Sixty percent of compound odontomas occurred in the canine area and 57.1% of complex odontomas in the molar areas. Impaction of permanent teeth (61.6%) was the most common complication on the adjacent teeth. Most odontomas (84.9%) were removed surgically and impacted permanent teeth were managed by surgical removal (53.2%), orthodontic treatment (25.5%), or surgical repositioning (6.4%). There was a statistically significant relation between age and preservation of the impacted permanent teeth associated with odontomas (p<0.01). Early detection and treatment of odontomas increase the possibility of preservation of the impacted tooth. Therefore, it would be suggested that periodic panoramic examination during the first and second decade of life might be beneficial for the early detection and better prognosis of odontomas.

    Full Text Available Abstract Background Degenerative spinal stenosis and instability requiring multilevel spine surgery has been associated with large blood losses. Factors that affect perioperative blood loss include time of surgery, surgical procedure, patient height, combined anterior/posterior approaches, number of levels fused, blood salvage techniques, and the use of anti-fibrinolytic medications. This study was done to evaluate the efficacy of tranexamic acid in reducing blood loss in spine surgery. Methods This retrospective case control study includes 97 patients who had to undergo surgery because of degenerative lumbar spinal stenosis and instability. All operations included spinal decompression, interbody fusion and posterior instrumentation (4-5 segments. Forty-six patients received 1 g tranexamic acid intravenous, preoperative and six hours and twelve hours postoperative; 51 patients without tranexamic acid administration were evaluated as a control group. Based on the records, the intra- and postoperative blood losses were measured by evaluating the drainage and cell saver systems 6, 12 and 24 hours post operation. Additionally, hemoglobin concentration and platelet concentration were reviewed. Furthermore, the number of red cell transfusions given and complications associated with tranexamic acid were assessed. Results The postoperative hemoglobin concentration demonstrated a statistically significant difference with a p value of 0.0130 showing superiority for tranexamic acid use (tranexamic acid group: 11.08 g/dl, SD: 1.68; control group: 10.29 g/dl, SD: 1.39. The intraoperative cell saver volume and drainage volume after 24 h demonstrated a significant difference as well, which indicates a less blood loss in the tranexamic acid group than the control group. The postoperative drainage volume at12 hours showed no significant differences; nor did the platelet concentration Allogenic blood transfusion (two red cell units was needed for eight patients

    The study was to comprehensively compare the postoperative outcome and imaging parameter characters in a short/middle period between the percutaneous endoscopic lumbar discectomy (PELD) and the internal fixation of bone graft fusion (the most common form is posterior lumbar interbody fusion [PLIF]) for the treatment of adjacent segment lumbar disc prolapse with stable retrolisthesis after a previous lumbar internal fixation surgery.In this retrospective case-control study, we collected the medical records from 11 patients who received PELD operation (defined as PELD group) for and from 13 patients who received the internal fixation of bone graft fusion of lumbar posterior vertebral lamina decompression (defined as control group) for the treatment of the lumbar disc prolapse combined with stable retrolisthesis at Department of Spine Surgery, the Third Hospital of Hebei Medical University (Shijiazhuang, China) from May 2010 to December 2015. The operation time, the bleeding volume of perioperation, and the rehabilitation days of postoperation were compared between 2 groups. Before and after surgery at different time points, ODI, VAS index, and imaging parameters (including Taillard index, inter-vertebral height, sagittal dislocation, and forward bending angle of lumbar vertebrae) were compared.The average operation time, the blooding volume, and the rehabilitation days of postoperation were significantly less in PELD than in control group. The ODI and VAS index in PELD group showed a significantly immediate improving on the same day after the surgery. However, Taillard index, intervertebral height, sagittal dislocation in control group showed an immediate improving after surgery, but no changes in PELD group till 12-month after surgery. The forward bending angle of lumbar vertebrae was significantly increased and decreased in PELD and in control group, respectively.PELD operation was superior in terms of operation time, bleeding volume, recovery period, and financial

    Chronic pancreatitis (CP) is a rare disease in Chile, without a clear explanation for this low prevalence. To analyze the characteristics of our patients with pancreatitis. Retrospective analysis of a database of patients with pancreatitis of a clinical hospital. Morphological proof of diagnosis (calcifications/calculi, alterations of ducts, local complication or histology) was obtained for every patient. History of acute pancreatitis was recorded and exocrine-endocrine function was assessed. We retrieved information of 121 patients with pancreatitis (86 males) in a period of 20 years. The number of cases increased markedly every five years. The calculated incidence and prevalence was 0.8/100,000/year and 6/100,000, respectively. Pancreatic calcifications were initially observed in 93 patients and became evident during the follow-up in another six patients. Severe pain or local complications occurred in 27 patients, requiring surgery in 10 or endoscopic treatment in 15. During the years of follow-up, 55 patients were free of symptoms. Exocrine and endocrine insufficiency was demonstrated and treated in 81 and 67 patients, respectively. Alcoholic etiology was evident in 40% of patients. In 29% no etiology was identified. Mapuche origin was exceptional. Late diagnosis of CP is common, since most of our patients presented with advanced stages. Even though CP is increasingly diagnosed in our hospitals, the number of cases is still far fewer when compared to other countries. Underdiagnosis alone cannot explain this difference and genetic factors might be of importance.

    Brucellosis is a public health problem that is prevalent in several developing countries. The clinical and laboratory characteristics of 164 cases of brucellosis in Bursa, Turkey, were retrospectively evaluated. The ages of the 164 patients ranged from 15-85 years. All of the patients underwent the Rose Bengal test and 163 (99.4%) patients tested positive. 122 (74.4%) patients were diagnosed with acute brucellosis, 31 (18.9%) with subacute brucellosis and 11 (6.7%) with chronic brucellosis. Focal involvement was found in 101 (61.6%) patients. Although patients with focal involvement had a higher white blood cell count (p = 0.002), those without focal involvement had higher aspartate transaminase and alanine transaminase values, and lower platelet values (p = 0.005, 0.007 and 0.039, respectively). Spondylodiscitis was observed on imaging in 58 (66.7%) of the 87 patients who presented with back pain. Among the 118 patients who were examined within the first month of treatment, 79 (66.9%) responded to treatment. The relapse rate was 11.6% among all 164 patients. Brucellosis should be considered as a differential diagnosis among patients who present with fever, and joint or back pain. Focal involvement should be investigated in the presence of leucocytosis, and subacute or chronic forms of brucellosis. To identify cases of spondylodiscitis, radiography should be performed in patients who present with back pain. Copyright: © Singapore Medical Association

    "Be Clear on Cancer" (BCOC) was a national campaign to raise awareness of breast cancer in women over seventy years old. Cancer Research UK conducted this campaign from 03 February 2014 to 15 March 2014. This study assesses its impact on breast care services. BCOC campaign guidelines for hospital trusts were used as standard comparator for this retrospective case-control study. All new patients referred to breast clinic over four months from February 2014 were included, and compared to the same period in 2013. Information was recorded for referrals, biopsy rates and pathological diagnoses. Intra & inter-group comparisons were performed. 1646 patients were included. An increase of 25.2%(n = 184) was observed in referrals in 2014(n = 915) compared to 2013(n = 731). Cancer detection rates went down significantly (P = 0.002,Chi-square) in 2014 (5.1%,n = 47) compared to 2013 (9.0%,n = 66) due to the increase in number of referrals. In the over 70s group, a higher than predicted increase of 64.2%(n = 52) in all referrals, and 8%(n = 44) in two-week wait referrals was observed. The number of biopsies and cancers detected remained stable although the proportions undergoing biopsies (2014-29.3%,n = 39/133 versus 2013-38.3%,n = 31/81) or being diagnosed with cancer (2014-19.5%,n = 26/133 versus 2013-30.9%,n = 25/81) declined significantly (P = 0.001,McNemar) during the campaign due to an inflation in the number of referrals. Despite the overall reduction, cancer detection rate for biopsies performed remained significantly high in the over 70s (66.7%,n = 26/39) when compared with the under 70s (23.9%,n = 21/88) during the campaign. Although "Be Clear on Cancer" campaign resulted in a significant increase in breast cancer referrals, it did not translate into an increase in biopsy rates or cancer detection rates. The amount of work generated for the hospital because of this campaign was far greater than the predicted increase from campaign pilots

    Bracing could be efficacious, given good compliance and quality of braces. Recently the SOSORT Brace TREATMENT Management Guidelines (SBTMG) have highlighted the perceived importance of the professional teams surrounding braced patients. To verify the impact of a complete rehabilitation team in the adolescent patient with bracing. Design. Initial cross-sectional study, followed by a retrospective case-control study. Thirty-eight patients (15.8 ± 1.6 years; 26 females; 10 hyperkyphosis, 28 scoliosis of 29.2 ± 7.9° Cobb) extracted from a single orthotist database (between January 1, 2008 and September 1, 2009) and treated by the same physician; brace wearing at least 15 hours/day for a minimum of 6 months; age 10 or more. Braces: Sforzesco, Sibilla, Lapadula or Maguelone. Exercises: SEAS. Two questionnaires filled in blindly by patients: SRS-22 and one especially developed and validated with 25 questions on adherence to treatment. Groups (main risk factor): TEAM (private institute: satisfied 44/44 SOSORT criteria; grade of teamwork, "excellent") included 13 patients and NOT 25 (National Health Service Rehabilitation Department: 35/44 SOSORT criteria respected; grade, "insufficient"). TEAM was more compliant to bracing than NOT (97 ± 6% vs. 80 ± 24%) and performed nearly double the exercises (38 ± 12 vs. 20 ± 13 minutes/session). The self-reduction of bracing was significant in NOT (from 16.8 ± 3.7 to 14.8 ± 4.9 hours/day, , Pversus 7% of TEAM (P < 0.05). The populations did not differ at the baseline studied outcomes. The absence of a good team surrounding the patient increases by five times the risk of reduced compliance to bracing (odds ratio OR 5.5 - 95% confidence interval 95CI 3.6-7.4), along with more than 15 times that of QoL problems (OR 15.7 - 95CI 13.6-17.9) and pain (OR 16.8 - 95CI 14.5-19.1). Provided the limits of this first study on the topic, the SBTMG seems to be important for brace treatment

    To assess the direct intraoperative and postoperative costs in women undergoing total laparoscopic hysterectomy and fast-track open hysterectomy. A retrospective review of the direct hospital-related costs in a matched cohort of women undergoing total laparoscopic hysterectomy (TLH) and fast-track open hysterectomy (FTOH) at a tertiary hospital. All costs were calculated, including the cost of advanced high-energy laparoscopic devices. The effect of the learning curve on cost in laparoscopic hysterectomy was also assessed, as was the hospital case-weighted cost, which was compared with the actual cost. Fifty women were included in each arm of the study. TLH had a higher intraoperative cost, but a lower postoperative cost than FTOH (AUD$3877 vs AUD$2776 P funding model in our hospital is inaccurate when compared to directly calculated hospital costs. © 2013 The Authors ANZJOG © 2013 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    The aim of this study was to analyze the association between the presence of actinic lesions (solar keratosis and non-melanoma skin cancer) and osteoporotic hip fractures in older patients. Both pathologies are common conditions in this age group. Since cumulative sun exposure is difficult to quantify, the presence of actinic lesions can be used to indirectly analyze the association between ultraviolet radiation and osteoporotic hip fractures. This was an observational case-control study. We reviewed the centralized medical records of patients with hip fracture (cases, n = 51) and patients with other diseases hospitalized in the same institution and period (controls, n = 59). The mean age of the patients was 80 ± 8.3 years (range 50-103 years). Differences in maternal hip fracture history were found between cases and controls (14.8 and 8 %, respectively; p = 0.047). Falls history in the past year was higher in cases than in controls (p < 0.0001). Actinic lesions were observed in 32.7 % of patients (prevalence rate 23.5 % in cases, 40.7 % in controls; p = 0.04). When considering patients with actinic lesions, controls have a higher FRAX score compared with cases. Although sun exposure is recommended for bone health, it represents a risk factor for actinic lesions. The presence of actinic lesions may indicate a lower osteoporotic hip fracture risk. A balance between adequate lifetime sun exposure and protection against its adverse effects is required for each patient, in the context of geographic location.

    Full Text Available To evaluate a holistic multidisciplinary outpatient model of care on hospital readmission, length of stay and mortality in older patients with multimorbidity following discharge from hospital.A pilot case-control study between March 2006 and June 2009 of patients referred on discharge to a multidisciplinary, integrated outpatient model of care that includes outpatient follow-up, timely GP communication and dial-in service compared with usual care following discharge, within a metropolitan, tertiary referral, public teaching hospital. Controls were matched in a 4:1 ratio with cases for age, gender, index admission diagnosis and length of stay.Non-elective readmission rates, total readmission length of stay and overall survival.A total of 252 cases and 1008 control patients were included in the study. Despite the patients referred to the multidisciplinary model of care had slightly more comorbid conditions, significantly higher total length of hospital stay in the previous 12 months and increased prevalence of diabetes and heart failure by comparison to those who received usual care, they had significantly improved survival (adjusted hazard ratio 0.70 95% CI 0.51-0.96, p = 0.029 and no excess in the number of hospitalisations observed.Following discharge from hospital, holistic multidisciplinary outpatient management is associated with improved survival in older patients with multimorbidity. The findings of this study warrant further examination in randomised and cost-effectiveness trials.

    The first large-scale study of thyroid cancer among young people in Russia following the Chernobyl accident was conducted. The study population consists of all children and adolescents (17 years and less) who were resided in Kaluga, Orel and Tula oblasts of Russia at the time of Chernobyl accident. Kaluga, Orel and Tula oblasts are approximately equally contaminated oblasts of Russia (up to 15 Ci/km2 for cesium-137). All prevalent and new carcinoma cases from 1 January 1992 to 31 December 1998 were collected in 1997-1998 years as a result of joint project on thyroid disease conducted by the Medical Radiological Research Center (Russia), International Agency for Research on Cancer (France) and Sasakawa Memorial Health Foundation (Japan). Cases of thyroid cancer were found through the Russia National Medical and Dosimetric Registry and Russian Oncology Dispensaries. All cases were independently hystologically verified by the international panel of pathologists from Russia, Belarus and Europe. There were 12 cases in Kaluga, 27 cases in Orel and 23 cases in Tula oblasts. For each case were randomly selected two and four controls: two controls were matched on age, sex and on settlement of residence at the time of accident; four controls were matched on age, sex and on oblast of residence at the time of accident. Each patient and corresponding controls were examinated by the high-resolution ultrasonographic instrument and were interviewed by special trained medical staff. The new technique for reconstruction of the individual dose of internal irradiation of thyroid with incorporated 131 I was developed. The method allows to take into account major factors influencing formation thyroid doses of the population: (1) three sources of receipt 131 I in organism of the man: inhalation, consumption of milk and green vegetables; (2) types of food production: public and private (individual) sectors of its (her) manufacture; (3) weather conditions of spring of 1986 in regions of

    Ovarian hyperstimulation syndrome (OHSS) is the most serious complication of IVF/ICSI therapy. The pathophysiology and etiology of the disease is still not fully clarified. To assess whether polymorphisms of the VEGF/VEGF-receptor system contribute to the occurrence of ovarian hyperstimulation syndrome (OHSS), we performed a retrospective analysis of 116 OHSS patients, and 124 female controls. The following SNPs were genotyped: Rs2071559 (VEGFR2-604); rs2305948 (VEGFR2-1192); rs1870377 (VEGFR2-1719); rs2010963 (VEGF-405); and rs111458691 (VEGFR1-519). Odds ratios (ORs) were estimated with a 95% confidence interval (CI). Linkage disequilibrium (LD) analysis was performed in the three loci of the VEGFR2 gene. We found an overrepresentation of the T allele of the VEGFR1-519 polymorphism in OHSS patients (P = 0.02, OR: 3.62, CI: 1.16 - 11.27). By genotype modeling, we found that polymorphism of VEGFR1-519 and VEGF-405 showed significant differences in patients and controls (p = 0.02, OR: 3.79 CI: 1.98 - 11.97 and p = 0.000005, OR: 0.29, CI: 0.17 - 0.50). LD analysis revealed significant linkage disequilibrium in VEGFR2. Polymorphisms in the VEGFR2 gene and in the VEGF gene are associated with the occurrence of OHSS. This strengthens the evidence for an important role of the VEGF/VEGF- receptor system in the occurrence of OHSS.

    Full Text Available Objective Indians have the highest risk rates for coronary artery disease (CAD among all ethnic groups. There is a paucity of data on the risk factors and clinical markers associated with premature CAD. We aimed to determine whether young CAD is due to preventable lifestyle-related factors and cutaneous clinical markers are useful in identifying at-risk patients. Design Single-centre retrospective study. Setting Tertiary care center. Participants A total of 292 patients (age ≤40 years who presented with acute CAD between January 2005 and June 2009 and 92 age, and gender-matched controls. Major outcome measures Details of smoking, family history of premature CAD, waist size, blood sugar and lipid profile. Clinical evidence of arcus juvenilis, premature greying of hair and premature baldness sought. Results Dyslipidaemia (91%, smoking (74.3%, low high-density lipoprotein cholesterol (HDL-C (68.9%, central obesity (47.7% and greying of hair (34.9% were the most commonly associated factors. Compared with male patients, females had greater prevalence of dyslipidaemia, low HDL-C, central obesity, hypertension, diabetes and family history of premature CAD. The presence of cutaneous markers was significantly associated with premature CAD. Conclusions CAD in young Indian people is multifactorial; dyslipidaemia, low HDL-C, smoking, hypertension, central obesity and family history of premature CAD are the most common risk factors. Smoking in men and central obesity in women are the most prevalent factors. Clinicians should be highly suspicious of patients with presence of cutaneous markers, and they should be followed intensively for lifestyle modifications.

    Avascular necrosis of bone (AVN) is an important complication of systemic lupus erythematosus (SLE). Corticosteroid therapy has been underlined as a main risk factor for osteonecrosis. However, AVN development in patients who have never received corticosteroid and the absence of AVN in the majority of the patients, who received corticosteroid, propose a role for non-corticosteroid risk factors in AVN development. This case-control study included two subsets: oral corticosteroid (66 AVN and 248 non-AVN patients) and pulse-therapy subset (39 AVN and 312 non-AVN patients) who have attended our Lupus clinic from 1979 to 2009. Patients received similar cumulative dose corticosteroid, equal maximum dose and 1-year maximum dose of corticosteroid. The demographic data (including sex, age of disease onset, age at the diagnosis of AVN), organs involvement, SLE Disease Activity Index (SLEDAI), Systemic Lupus International Collaborating Clinics/American College of Rheumatology-Damage index (SLICC/ACR-DI), number of disease flare ups were compared between two subsets. The mean age of SLE onset was younger (P value = 0.04) in the AVN patients. In oral corticosteroid subset, malar rash (P value AVN patients, whereas psychosis (P value = 0.03) was significantly more prevalent AVN subset in oral corticosteroid subset. In corticosteroid pulse subset, no significant difference in clinical features was noted. In oral corticosteroid subset, younger age of disease onset and psychosis were significantly associated with AVN, whereas malar rash and oral ulcer showed negative association AVN.

    Full Text Available Introduction: Modern liver surgery in the Sudan started at our institution, The National Ribat University Hospital, in 2002. This study aimed to assess the perioperative events of hepatocellular carcinoma (HCC resection in our institution during the period January 2002 to December 2013 compared to hepatectomies for benign liver pathologies. Methods: The medical records of 114 patients subjected to hepatectomy were divided into the HCC group (cases, and benign group (controls. The characteristics and perioperative events of both groups were assessed and compared. Results: The mean age of the HCC patients was 58.6 ± 7.7 years. The majority of liver resections in the HCC group were minor (72.7%. The mean intraoperative blood loss was 918.8 ml in the HCC group and 720 ml in benign resections group and the difference between them was not significant, p = 0.129. The mean operative duration of HCC resection was 4 hours. The major postoperative complications were encountered in 16 patients (36.4% in the HCC group. HCC group thirty-day postoperative mortality was 9.1%, (n = 4 patients while no patient of the benign group (n = 60 died within that duration, p = .030. Logistic regression multivariate analysis revealed massive bleeding as an independent predictor for major postoperative morbidity, Odds ratio [OR] = 5.899, 95%, Confidence Interval [95% CI], 1.129–30.830, p = .035. Discussion: Our results revealed outcome parameters comparable with the international reports. Conclusion: Further improvements in hepatic surgery in general, and HCC in particular is inevitable.

    Shiny white streaks (SWSs) are best visualized with polarized dermoscopy and correlate with dermal fibroplasia histopathologically. SWSs have been described at higher frequencies in melanomas than in benign nevi. We assessed the diagnostic value of different patterns of SWSs and their histologic correlate in melanocytic lesions. Polarized dermoscopic images of 1507 histopathologically diagnosed melanocytic neoplasms were analyzed for presence and pattern of SWSs. Histology was also reviewed for correlation. Among 1507 melanocytic neoplasms, SWSs were observed in 31 of 144 melanomas (22%) and 22 of 1363 benign neoplasms (1.6%) (P < .001). The sensitivity and specificity of SWSs for melanoma were 22% and 98%, respectively. Diffuse SWSs exhibited the greatest diagnostic value for melanoma, with sensitivity of 11.8% and specificity of 99.5%. Focal central and peripheral SWSs were comparable in diagnostic significance. The presence of SWSs was highly uncommon in dysplastic nevi, whereas in certain benign subgroups of nevi such as Spitz nevi and atypical genital special site nevi, SWSs were not uncommon. Diffuse SWSs correlated with greater breadth of deep fibroplasia than focal SWSs (P = .009), and SWSs correlated with greater Breslow depth among melanomas (P = .007). This study was retrospective. Polarized dermoscopy is a valuable diagnostic tool in the identification of SWSs, a feature that is highly specific for melanoma. Copyright © 2017 American Academy of Dermatology, Inc.

    The purpose of this study was to explore the effect of lower limb rehabilitation gymnastics on postoperative rehabilitation in elderly patients with femoral shaft fracture after undergoing intramedullary nail fixation surgery.We collected medical records of elderly patients aged ≥ 60 years with femoral shaft fracture between 03/2010 and 03/2015 in Longyao County Hospital. Totally, 160 patients were identified and divided into the intervention group (n = 80) and the control group (n = 80). During the postoperative period, the intervention group received lower limb rehabilitation gymnastics treatment for 3 months, but the control group did not. All patients were routinely asked to return hospital for a check in the 1st postoperative week, as well as the 2nd week, the 1st month, and the 3rd month, after surgery. The clinical rehabilitation effect was evaluated by checking lower limb action ability, detecting the lower limb deep venous thrombosis (DVT), scoring muscle strength of quadriceps and visual analog scale (VAS) score, and performing satisfaction survey.At the 1st week and 2nd week after surgery, the clinical rehabilitation effect in the intervention group was better regarding lower limb action ability, lower limb DVT, muscle strength of quadriceps, VAS score, and patient satisfaction, as compared with the control group. However, there was no significant difference at the 1st month and the 3rd month after surgery when comparing the intervention group to the control group.In the early postoperative stage, lower limb rehabilitation gymnastics can effectively improve the recovery of lower limb function, beneficial to reducing postoperative complications such as lower limb DVT and muscle atrophy, and increasing patient satisfaction rate.

    To evaluate post-surgical postural stability when treating patients with remaining vestibular function with intratympanic gentamicin (PREHAB) prior to schwannoma surgery. 44 consecutive patients with some form remaining vestibular function scheduled for vestibular schwannoma surgery. 20 were medically deafferented with intratympanic gentamicin before surgery and 24 were not. Both groups were of the same age, had the same tumor size, same type of surgery, and same perioperative sensory rehabilitation (training exercises), and no surgical complications. Postural stability measured as energy expenditure while standing on a force platform during vibratory stimulation of the calf muscles, performed prior to surgery (or gentamicin treatment) and 6 months after surgery. Patients pretreated with gentamicin had significantly better postural stability at the time for follow-up (p postural challenge (p control their stability (p postural control system benefited from a better short-term (adaptation) and long-term (habituation) recovery, when experiencing a postural challenge or resolving a sensory conflict. The benefits could be attributed to; active and continuous motor learning as the vestibular function slowly attenuates; no concomitant central nervous dysfunction due to effects from neurosurgery, thus allowing time for a separate unimpeded recovery process with more limited challenges and objectives; and the initiation and certain progression of sensory reweighting processes allowed prior to surgery. In contrast, worse compensation could be due to; immobilization from nausea after surgery, harmful amount of stress and cognitive dysfunction from the combination of surgical and sensory trauma and an abrupt vestibular deafferentation and its consequences on sensory reweighting.

    Sclerodermas are rare affections which can be located or generalized. Localized form is the most frequent. The purpose of this study was to describe epidemiologic, clinics, biological, immunological, therapeutic, evolutionary characteristics of the localized scleroderma through a personal series and the data of the literature. We have performed a retrospective study on all patients followed in the department of dermatology of the Hospital Charles Nicole during 14 years period. Our study was about 92 cases of localized scleroderma (73 were females and 19 males). The mean age was 35 years (between 2 and 72 years). The majority of localised sclerodermas (66.2% of the cases) appeared before 40 years with a maximum of frequency between 10 and 30 years (41.6%). Only 11.9% of the cases were observed before 10 years. They were 51 cases (55%) of morphea, 35 cases (38%) of scleroderma in bands including 32 linear scleroderma and 3 scleroderma en coup de sabre, 5 cases (5.5%) of generalized morphea and 1 case (0.15%) of deep morphea. Average therapeutic was specified among 63 patients (87%), and the evolution could be appreciated among 45 patients. The epidemiologic data observed in our series are comparable with those reported in the literature. Therapeutic difficulties and risks of functional after-effects, particular in scleroderma in bands, remain the principal concern for all the authors.

    Full Text Available Background: The management of odontoid fracture has evolved but controversy persists as to the best method for Type II odontoid fractures with or without atlantoaxial (AA instability. The anterior odontoid screw fixation can be associated with significant morbidity while delayed odontoid screw fixation has shown to be associated with reasonable good fusion rates. We conducted a retrospective analysis to evaluate the outcome of a trial of conservative management in type II odontoid fractures without atlantoaxial instability (Group A followed by delayed odontoid screw fixation in cases in which fusion was not achieved by conservative treatment. The outcome of type II odontoid fracture with AA subluxation (Group B was also analysed where closed reduction on traction could be achieved and in those atlantoaxial subluxations that were irreducible an intraoperative reduction was done. Materials and Methods: A retrospective evaluation of 53 cases of odontoid fractures treated over a 9-year period is being reported. All odontoid fractures without AA instability (n=29 were initially managed conservatively. Three patients who did not achieve union with conservative management were treated with delayed anterior screw fixation. Twenty-four cases of odontoid fractures were associated with AA instability; 17 of them could be reduced with skeletal traction and were managed with posterior fusion and fixation. Of the seven cases that were irreducible, the initial three cases were treated by odontoid excision followed by posterior fusion and fixation; however, in the later four cases, intra operative reduction was achieved by a manipulation procedure, and posterior fusion and fixation was performed. Results: Twenty-six of 29 cases of odontoid fracture without AA instability achieved fracture union with conservative management whereas the remaining three patients achieved union following delayed anterior odontoid screw fixation. 17 out of 24 odontoid fracture with

    To evaluate the volumetric changes and peri-implant health at implant sites with and without previous soft tissue grafting over a 5-year observation period. In 18 partially edentulous patients, dental implants were placed in the esthetic zone (15-25) with simultaneous guided bone regeneration, followed by submerged healing. During the healing phase, eight patients (test) received a subepithelial connective tissue graft, whereas 10 patients (control) did not receive any soft tissue augmentation. Subsequently, abutment connection was performed and final reconstructions were inserted. Impressions were taken 1 week after crown insertion and at 5 years. Obtained casts were scanned and superimposed for volumetric and linear measurements. The mean distance (MD) in the mid-buccal area between the two surfaces and the differences in buccal marginal mucosal level (bMML change ) and in ridge width (RW change ) were evaluated. Peri-implant health was assessed using probing pocket depth (PPD) values, plaque index (PlI) and bleeding on probing (BOP). At a median follow-up time of 60.5 months a median MD of -0.38 mm (Min: -0.94; Max: -0.03) (test) and of -0.51 mm (Min: -0.76; Max: 0.05) (control) was calculated. The level of the margo mucosae (bMML change ) demonstrated a median loss of -0.42 mm (Min: -1.1; Max: -0.01) (test) and of -0.33 mm (Min: -1.02; Max: 0.00) (control). The median RW change ranged between -0.44 mm and -0.73 mm (test) and between -0.49 mm and -0.54 mm (control). Mean PPD values slightly increased, whereas PlI and BOP remained stable over time in both groups. None of the comparisons between the groups revealed statistically significant differences (P > 0.35). A small sample size must be considered, however. Limited by a retrospective case-control study design, implant sites with and without soft tissue grafting on the buccal side revealed only minimal volumetric and linear changes and stability of peri-implant parameters over 5 years. © 2017

    Primary intracranial germinomas (PIGs) are rare malignant brain tumors that represent approximately 0.2% to 1.7% of all primary intracranial tumors. PIGs have infrequent, but there is a possibility of spinal cord metastases. In this study, clinical outcomes of five consecutive PIGs have been presented. Medical records were retrospectively reviewed in 1,849 cases of intracranial tumors who underwent surgery between the years 2005 and 2015 and cases confirmed as germinoma histopathologically were included in this study. Five cases of PIGs were detected in two female (40%) and 3 male (60%) patients. The mean age was 15.2±5.6 (8-23) years. The mean follow-up period was 52.3±56.4 (9-135) months. The most common complaint was headache (60%), followed by nausea±vomiting (40%). Four cases (80%) affected the suprasellar region while the fifth patient"s tumor was localized in the pineal region. The duration between the initial symptom and time of surgical intervention ranged between 15 days and 2 months. Twelve months after the first operation, one patient presented with drop seeding metastasis. Four-year survival (with exception of the case that died as a early surgical complication) was 100%. Gross total resection (GTR) was achieved in one patient. Surgical mortality rate was 20%. PIGs" morbidity rate was 60%. PIG is a mostly malignant tumor that generally affects the pediatric age group. They are radiosensitive tumors. Subtotal or near-total resection using stereotactic guide or direct surgery to confirm the histopathological diagnosis followed by chemotherapy and whole brain or in some cases craniospinal radiotherapy rather than GTR is therefore the treatment of choice.

    Conclusion: This retrospective case series describes, for the first time, the clinical outcomes in a series of patients treated with radiotherapy for bone hydatid disease. Although no direct comparison between the treatment groups could be made due to methodological limitations of the study design, this study indicates that well-designed prospective randomized controlled clinical trials assessing radiotherapy may be warranted in patients with inoperable hydatid disease of the bones.

  18. Retrospective Cost Adaptive Control with Concurrent Closed-Loop Identification

    Science.gov (United States)

    Sobolic, Frantisek M.

    Retrospective cost adaptive control (RCAC) is a discrete-time direct adaptive control algorithm for stabilization, command following, and disturbance rejection. RCAC is known to work on systems given minimal modeling information which is the leading numerator coefficient and any nonminimum-phase (NMP) zeros of the plant transfer function. This information is normally needed a priori and is key in the development of the filter, also known as the target model, within the retrospective performance variable. A novel approach to alleviate the need for prior modeling of both the leading coefficient of the plant transfer function as well as any NMP zeros is developed. The extension to the RCAC algorithm is the use of concurrent optimization of both the target model and the controller coefficients. Concurrent optimization of the target model and controller coefficients is a quadratic optimization problem in the target model and controller coefficients separately. However, this optimization problem is not convex as a joint function of both variables, and therefore nonconvex optimization methods are needed. Finally, insights within RCAC that include intercalated injection between the controller numerator and the denominator, unveil the workings of RCAC fitting a specific closed-loop transfer function to the target model. We exploit this interpretation by investigating several closed-loop identification architectures in order to extract this information for use in the target model.

    Fournier's gangrene is a rapidly progressing necrotizing fascitis that affects the perineal and genital area. Mortality still remains high. The aim of this study was to evaluate the epidemiological progression and morbidity-mortality of Fournier's gangrene at our centre over the past 10 years. Retrospective study of 41 patients treated for Fournier's gangrene between 1998 and 2007. Variables studied included, demographic variables, aetiology, microbiology, surgical and antibiotic treatment, morbidity, and mortality. The mean age of the patients was 60, and 93% were male. The most common co-morbidity was diabetes (49%), followed by alcoholism (46%) and immunosuppression or neoplasia (34%). The origin was perianal in 66% of cases, followed by a urological origin (32%). The median time from the onset of symptoms to diagnosis was 3 days. Several surgical debridements were required in 49% of the patients, and the mortality rate was 29%. Most cases had positive cultures (93%), and in 76% more than one microorganism was isolated (enterobacteriaceae and anaerobic flora). In the bivariate analysis, antimicrobial treatment with carbapenems and the absence of systemic complications were associated with lower mortality. Fournier's gangrene continues to be a severe surgical emergency, with a high mortality rate. Early diagnosis and aggressive surgical and antibiotic therapy are necessary for adequate management.

    Full Text Available Spontaneous pneumothorax (SP is relatively common in clinical practice and occurs more frequently in young, tall thin men, and in smokers. However, simultaneous bilateral spontaneous pneumothorax (SBSP is a rare clinical condition that often presents with significant respiratory distress. It is often dangerous; therefore, the chest drain should be inserted immediately. In this study, simultaneus bilateral spontaneus pneumothoraces cases were divided into two groups and retrospectively evaluated according to age, sex, diagnostic methods, treatments, and results. Material and Methods :Between January 2006 and May 2009, 11 patients with SBSP were enrolled into our study. Age, gender, underlying lung disease, smoking history, symptoms, diagnosis, treatment type, surgical indication, morbidity, recurrence, mortality, duration of chest tube and postoperative hospital stay of the patients were reviewed. Arterial blood gas values (before and after intervention in patiens with primary and secondary spontaneous pneumothorax were evaluated. Results; 7 patients (63.63 % were male and 4 patients (36.37 % were female and their mean age was 34,5±6.81 years. There were 4 (36.37% primary SP and 4 (36.37% secondary SP patients. Chronic obstructive pulmonary disease (COPD was the most common cause in secondary SP patients. In two (18.18% patients recurrency were observed. Eight (72.72% patients had smoking history. The most common symptom in both groups was dyspnea. All patients had immediate bilateral chest tubes on admission. We treated these patients with chest drain insertion, VATS (Video-Assisted Thoracoscopic Surgery, axillary thoracotomy, and chemical pleurodesis. Postoperative morbidity was detected in 3 (27.27% patients (prolonged air leak in 1 case, empyema in 1 case and pneumonia in 1 case. No mortality was observed in alll cases. Recurrence developed in 3 (27.27% patients in this series. Conclusions: An urgent and effective treatment requires in the

    The aims of this paper were to review our experience with necrotizing fasciitis at Middlemore Hospital and to define the trends in incidence, inpatient mortality and microbiological profile. A computerized search of the electronic medical records was undertaken to identify adult patients with a diagnosis of necrotizing fasciitis between January 2000 and December 2010. A retrospective review of the clinical records was performed. Of the 138 patients with necrotizing fasciitis identified, 129 had their diagnosis confirmed at operation. The mortality at 30 days was 20.3% (95% confidence interval (CI) 13.9%-28.0%). There was a significant reduction in hospital mortality in each successive year of the study period with an odds ratio of 0.84 (95% CI 0.71-0.98, P = 0.03). A pattern of increasing incidence was noted until February 2004 (95% CI September 2002-July 2005). This was followed by a significant decrease in incidence. The empirical antibiotic regime of clindamycin, gentamicin and penicillin provides satisfactory cover against 95% of the causative pathogens. This represents the largest single-centre published case series in New Zealand. Despite concerns of increasing incidence and mortality associated with necrotizing fasciitis in New Zealand, the experience in South Auckland shows a decrease in incidence of necrotizing fasciitis since 2004 and a statistically significant decreasing trend in hospital mortality. © 2015 Royal Australasian College of Surgeons.

    Full Text Available Introduction: Duodenal stump fistula (DSF after gastrectomy has a low incidence but a high morbidity and mortality, and is therefore one of the most aggressive and feared complications of this procedure. Material and methods: We retrospectively evaluated all DSF occurred at our hospital after carrying out a gastrectomy for gastric cancer, between January 1997 and December 2014. We analyzed demographic, oncologic, and surgical variables, and the evolution in terms of morbidity, mortality and hospital stay. Results: In the period covered in this study, we performed 666 gastrectomies and observed DSF in 13 patients (1.95%. In 8 of the 13 patients (61.5% surgery was the treatment of choice and in 5 cases (38.5% conservative treatment was carried out. Postoperative mortality associated with DSF was 46.2% (6 cases. In the surgical group, 3 patients developed severe sepsis with multiple organ failure, 2 patients presented a major hematemesis which required endoscopic haemostasis, 1 patient had an evisceration and another presented a subphrenic abscess requiring percutaneous drainage. Six patients (75% died despite surgery, with 3 deaths in the first 24 hours of postoperative care. The 2 patients who survived after the second surgical procedure had a hospital stay of 45 and 84 days respectively. In the conservative treatment group the cure rate was 100% with no significant complications and an average postoperative hospital stay of 39.5 days (range, 26-65 days. Conclusion: FMD is an unusual complication but it is associated with a high morbidity and mortality. In our experience, conservative management has shown better results compared with surgical treatment.

    To determine the clinical characteristics of Continuous Neuropathic Orofacial Pain in patients that suffer Persistent Idiopathic Facial Pain (PIFP), Painful Post-Traumatic Trigeminal Neuropathy (PPTTN) or Burning Mouth Syndrome (BMS) and to describe their treatment. A retrospective observational study was made, reviewing the clinical history of the patients diagnosed with Continuous Neuropathic Orofacial Pain between 2004 and 2011 at the Orofacial Pain Unit of the Master of Oral Surgery and Implantology of the University of Barcelona and at the Orofacial Pain Unit of the Teknon Medical Center of Barcelona. The average age of the patients with Continuous Neuropathic Orofacial Pain was 54.5, with a clear female predominance (86.9%, n=20). Of all patients, 60.9% (n=14) were suffering a PIFP, 21.7% (n=5) had a BMS and 17.4% (n=4) were presenting a PPTTN. The pain quality described by the patients with Continuous Neuropathic Orofacial Pain was oppressive (43.47%, n=10), widely represented by patients with PIFP, and burning (39.13%, n=9) being the only quality that described patients with BMS. The treatment carried out with the patients was only pharmacologic. The most used drugs for the treatment of PIFP and PPTTN were clonazepam (50%, n=9) and amitriptyline (44.44%, n=8). However, a 55.5% (n=10) of the patients with PIFP or PPTTN required the association of two or more drugs for a correct pain control. All the patients with BMS responded satisfactorily to clonazepam. Continuous Neuropathic Orofacial Pain is a little known condition among the general population, physicians and dentists. This favors a late diagnosis and inaccurate treatments which entail unnecessary suffering. It is important to inform both the general population and health professionals concerning this painful condition.

    To evaluate the clinico-pathological findings, response to treatment and prevalence of complications in dogs with primary hypoparathyroidism. Retrospective study of 17 dogs presenting to the University of Melbourne Veterinary Clinical Centre and Murdoch University Veterinary Hospital over a 15 year period (1990 to 2004). Case records were evaluated for signalment, body weight, diet type, historical and clinical findings, serum total calcium, phosphate, albumin and parathyroid hormone concentrations, urinary fractional excretion ratios of calcium and phosphate, electrocardiogram (ECG) results, treatments administered, outcome and period of follow-up. The most common breeds identified were St Bernard (three dogs), Chihuahua (two dogs), German Shepherd (two dogs) and Jack Russell Terrier (two dogs). Three dogs were cross bred. Seizures, muscle tremors and fasciculations, stiff gait, tetany, muscle cramping, behavioural change and hyperventilation were the most common clinical signs. Vomiting, inappetence, diarrhoea, abdominal pain, hyperthermia, facial pruritus, ataxia, weakness, cataracts, and circling also occurred with less frequency. The mean duration of observed clinical signs preceding diagnosis was 33 days (median 13 days, range 1 to 173 days). All dogs had marked hypocalcaemia with normal or mildly increased serum albumin concentrations. Mean phosphate concentrations were significantly higher in inappetent dogs (P = 0.049). Mean serum calcium concentrations were significantly lower in dogs with cataracts compared to those without (P = 0.046). There were no other significant relationships between serum calcium or phosphate concentrations and the clinical presentation or outcome. No significant correlations were identified between the presence of a particular clinical sign and the duration of clinical signs. ECGs were obtained in four dogs and all exhibited QT interval prolongation due to a ST-segment prolongation. Sixteen of 17 dogs were treated successfully

  9. Intercalated Injection, Target Model Construction and H 2 Performance of Retrospective Cost Adaptive Control

    Science.gov (United States)

    Rahman, Yousaf

    This dissertation extends retrospective cost adaptive control (RCAC) by devel- oping a novel interpretation of RCAC, wherein the retrospective cost minimization uses intercalated injection between the controller numerator and denominator to fit a specific closed-loop transfer function to a target model. The target model thus incor- porates the modeling information required by RCAC. To demonstrate the effect of the target model on closed-loop performance, RCAC is applied to a collection of problems that demonstrate adaptive pole placement, where the target model is used to place closed-loop poles; adaptive PID control, where RCAC adaptively tunes PID gains; and LQG cost minimization, where the optimality and closed-loop frequency response of RCAC is compared with the performance of discrete-time LQG controllers. Next, RCAC is applied to plants that are difficult to control using fixed gain con- trollers, including an aircraft lateral dynamics model that has an unknown transition from minimum-phase to nonminimum-phase (NMP) dynamics, as well as plants with severely limited achievable gain and delay margin. xvi. Methods are developed to control NMP plants without knowledge of the NMP zero. Specifically, a decentralized feedback-feedforward architecture as well as quasi- FIR controllers are considered, where the FIR controller operates in parallel with an internal model controller in order to follow commands for NMP plants without knowledge of the NMP zeros. Next, the following question is considered: Are all full-order dynamic compen- sators observer-based? It is shown that the only case where a dynamic compensator is not observer-based is the case where n is odd and the closed-loop spectrum has no real eigenvalues. Since this is the case, such controllers are necessarily suboptimal in the sense of LQG. This question is relevant to understanding the closed-loop pole locations arising from full-order RCAC compensators. Finally, retrospective cost model refinement (RCMR

    To analyse the association between water balance during the first 24h of admission to ICU and the variables related to chloride levels (chloride loading, type of fluid administered, hyperchloraemia), with the development of acute kidney injury renal replacement therapy (AKI-RRT) during patients' admission to ICU. Multicentre case-control study. Hospital-based, national, carried out in 6 ICUs. Cases were patients older than 18 years who developed an AKI-RRT. Controls were patients older than 18 years admitted to the same institutions during the study period, who did not develop AKI-RRT during ICU admission. Pairing was done by APACHE-II. An analysis of unconditional logistic regression adjusted for age, sex, APACHE-II and water balance (in evaluating the type of fluid). We analysed the variables of 430 patients: 215 cases and 215 controls. An increase of 10% of the possibility of developing AKI-RRT per 500ml of positive water balance was evident (OR: 1.09 [95% CI: 1.05 to 1.14]; P<.001). The study of mean values of chloride load administered did not show differences between the group of cases and controls (299.35±254.91 vs. 301.67±234.63; P=.92). The water balance in the first 24h of ICU admission relates to the development of IRA-TRR, regardless of chloraemia.

    1995-01-01

    A retrospective study of 160 pediatric neuroradiological examinations was conducted to determine the efficacy and safety of two sedation regimens (figs. 1, 2). For CT purposes, 150 patients (fig. 3) were orally given monosodium trichlorethyl phosphate syrup (100 mg/kg, with repeat 50 mg/kg if necessary), and for cerebral angiography, 15 patients (fig. 4) were intramuscularly administered a modified D.P.T. cocktail (pentazocine, chlorpromadine, promethazine). Failure rate in the oral syrup group was 6%, and in the D.P.T. group 6.7%. Diagnostic-quality images were obtained in 99.3% and 100%, respectively, of the two groups. There were neither mortality nor significant complications (table 3). It was concluded that each method had proved acceptably safe and effective, and that measures can be taken to further decrease complications and sedation failures. (author)

    Full Text Available Background and Aims: The anaesthetic challenge of awake craniotomy is to maintain adequate sedation, analgesia, respiratory and haemodynamic stability in an awake patient who should be able to co-operate during intraoperative neurological assessment. The current literature, sharing the experience on awake craniotomy, in Indian context, is minimal. Hence, we carried out a retrospective study with the aim to review and analyse the anaesthetic management and perioperative complications in patients undergoing awake craniotomy, at our centre. Methods: Medical records of 54 patients who underwent awake craniotomy for intracranial lesions over a period of 10 years were reviewed, retrospectively. Data regarding anaesthetic management, intraoperative complications and post-operative course were recorded. Results: Propofol (81.5% and dexmedetomidine (18.5% were the main agents used for providing conscious sedation to facilitate awake craniotomy. Hypertension (16.7% was the most commonly encountered complication during intraoperative period, followed by seizures (9.3%, desaturation (7.4%, tight brain (7.4%, and shivering (5.6%. The procedure had to be converted to general anaesthesia in one of patients owing to refractory brain bulge. The incidence of respiratory and haemodynamic complications were comparable in the both groups (P > 0.05. There was less incidence of intraoperative seizures in patients who received propofol (P = 0.03. In post-operative period, 20% of patients developed new motor deficit. Mean intensive care unit stay was 2.8 ± 1.9 day (1-14 days and mean hospital stay was 7.0 ± 5.0 day (3-30 days. Conclusions: ′Conscious sedation′ was the technique of choice for awake craniotomy, at our institute. Fentanyl, propofol, and dexmedetomidine were the main agents used for this purpose. Patients receiving propofol had less incidence of intraoperative seizure. Appropriate selection of patients, understanding the procedure of surgery, and

The incidence of respiratory and haemodynamic complications were comparable in the both groups (P > 0.05). There was less incidence of intraoperative seizures in patients who received propofol (P = 0.03). In post-operative period, 20% of patients developed new motor deficit. Mean intensive care unit stay was 2.8 ± 1.9 day (1-14 days) and mean hospital stay was 7.0 ± 5.0 day (3-30 days). 'Conscious sedation' was the technique of choice for awake craniotomy, at our institute. Fentanyl, propofol, and dexmedetomidine were the main agents used for this purpose. Patients receiving propofol had less incidence of intraoperative seizure. Appropriate selection of patients, understanding the procedure of surgery, and judicious use of sedatives or anaesthetic agents are key to the

    Full Text Available Numerous etiologies are responsible for cases of stroke in young adults. This study reviews the causes of two types of stroke (ischemic and intracerebral hemorrhage in young adults aged 15 to 40years, admitted to our center (a tertiary care center from 1997 to 2002. The purpose of this study is to determine the relative frequency of causes of stroke in young adults and compare this with published data in the literature. Using the codes 46.0 to 46.8 of the International Classification of Diseases- 10th Edition (ICD-10, cases were identified from the records of the stroke patients admitted in Imam Khomeini Hospital and the data were collected from their files using a comprehensive questionnaire. Forty-two cases of ischemic stroke (62% and 26 cases of intracerebral hemorrhage (38% were identified. The leading cause of ischemic stroke was cardioembolism (38.1%, followed by atherosclerosis in 5 cases (11.9%. Among cardiac causes infarction was attributable to consequences of rheumatic heart disease in 8 cases. In 3 cases a cessation or decrease in dose of warfarin was followed directly by an ischemic stroke. The most leading cause of intracerebral hemorrhage was hypertension (30.8%. Other causes were anticoagulant therapy, intratumoral hemorrhage, aplastic anemia, leukemia, arteriovenous malformations, and chronic active hepatitis. In conclusion, cardioembolism and hypertension were the most leading causes of ischemic and hemorrhagic stroke in young adults admitted in our hospital.

    Objective: This study aimed at documenting the spectrum of clinico pathological variations in hepatocellular carcinoma (HCC). Design: It was a retrospective study. Place and duration of Study: This study was conducted at the Institute of Nuclear Medicine and Oncology (INMOL) Hospital, Lahore from March 1997 to December 2000. Patients and Methods: The profiles of 118 patients with a biopsy proven hepatocellular carcinoma were analyzed in this period. The data collected was age, sex, clinical presentation and laboratory investigations including liver function tests, alpha fetoprotein and hepatitis profile. Results: Weight loss, jaundice and right upper quadrant abdominal pain were the main presenting symptoms. Out of 118 patients, alpha fetoprotein values were raised in 63(53.38%) patients 106 (89.83%) patients were found to have or have had HBV infections, and 92 (77.96%) patients were anti-HCV positive. Eighty-three (70.33%) patients were cirrhotic. History of alcohol abuse was bound in three patients. Conclusion: The common association of HCC with cirrhosis and hepatitis B and C suggests that vaccination against HBV on nationwide basis can decrease prevalence of this malignancy. There is a need to generate public awareness regarding the transmission of these viruses. Early diagnosis and intervention is also important to the successful management of HCC. (author)

    This retrospective clinical study aimed to assess patient's satisfaction with removable partial dentures (RPDs), as retention, chewing ability, aesthetics during the observation period. A total of 63 patients with RPDs, participated in this study. The following data was collected: Kennedy classification, denture design, denture support, satisfaction and success of RPD. The results showed that 73.6% of patients were wearing RPD for the first time and were finally satisfied. According to the denture support of RPDs, clasp-retained quadrangular RPDs were 100% effective, followed by triangular dental support 81% and linear dental support 47.7%. Comparison of RPDs with attachment with RPDs with claps assessed through Fisher exact test, confirmed statistically significant difference (P=0.008), despite retention; however, chewing ability and aesthetics showed no statistically significant difference with X 2 test on patient's satisfaction with RPD with or without attachment. Patients often would prefer not showing the anterior buccal clasps of RPD, therefore are generally satisfied more with RPD with attachment based on level of retention, chewing ability and aesthetics.

    Paediatric guidelines are lacking for management of spontaneous pneumothorax. Adult patient-focused guidelines (British Thoracic Society 2003 and 2010) introduced aspiration as first-line intervention for primary spontaneous pneumothorax (PSP) and small secondary spontaneous pneumothoraces (SSP). Paediatric practice is unclear, and evidence for aspiration success rates is urgently required to develop paediatric-specific recommendations. Retrospective analysis of PSP and SSP management at nine paediatric emergency departments across Australia and New Zealand (2003-2010) to compare PSP and SSP management. 219 episodes of spontaneous pneumothorax occurred in 162 children (median age 15 years, 71% male); 155 PSP episodes in 120 children and 64 SSP episodes in 42 children. Intervention in PSP vs SSP episodes occurred in 55% (95% CI 47% to 62%) vs 70% (60% to 79%), pmanagement, PSP and SSP management did not differ and ICC insertion was the continuing preferred intervention. Overall success of aspiration was lower than reported results for adults, although success was greater for small than for large pneumothoraces. Paediatric prospective studies are urgently required to determine optimal paediatric interventional management strategies. Published by the BMJ Publishing Group Limited.

    We report our experience of diagnosing and treating hepatic angiomyolipoma (HAML), a rare benign mesenchymal tumor. We analyzed retrospectively the clinicopathologic, radiological, and operative data of 25 patients who underwent surgery for HAML at our institute between November 2001 and May 2006. Most patients (20/25) were asymptomatic and had normal liver function. Ultrasonography (US) showed a heterogeneous hyperechoic mass in 13 of 23 patients, precontrast computed tomography (CT) showed that all of 12 lesions scanned were hypodense, and magnetic resonance imaging (MRI) showed hypointensity on T1-weighted images and hyperintensity on T2-weighted images in most (5/6) lesions. Marked enhancement in the arterial phase was seen in 10 of 12 lesions on CT scans and in 6 of 6 lesions on MRI scans. All tumors were composed of varying proportions of smooth muscle, adipose tissue, and blood vessels, and showed positive immunohistochemical staining for HMB-45. All patients underwent partial hepatectomy and there was no evidence of recurrence after a median follow-up of 43 months. The radiological features of HAML vary according to its histological components. The definitive diagnosis of HAML is challenging and depends on the presence of HMB-45-positive myoid cells. Hepatic angiomyolipoma is treated effectively with surgery and the prognosis is good. (author)

    Spinal pain in the paediatric population is a significant health issue, with an increasing prevalence as they age. Paediatric patients attend for chiropractor care for spinal pain, yet, there is a paucity of quality evidence to guide the practitioner with respect to appropriate care planning. A retrospective chart review was used to describe chiropractic management of paediatric neck pain. Two researchers abstracted data from 50 clinical files that met inclusion criteria from a general practice chiropractic office in the Greater Toronto Area, Canada. Data were entered into SPSS 15 and descriptively analyzed. Fifty paediatric neck pain patient files were analysed. Patients' age ranged between 6 and 18 years (mean 13 years). Most (98%) were diagnosed with Grade I-II mechanical neck pain. Treatment frequency averaged 5 visits over 19 days; with spinal manipulative therapy used in 96% of patients. Significant improvement was recorded in 96% of the files. No adverse events were documented. Paediatric mechanical neck pain appears to be successfully managed by chiropractic care. Spinal manipulative therapy appears to benefit paediatric mechanical neck pain resulting from day-today activities with no reported serious adverse events. Results can be used to inform clinical trials assessing effectiveness of manual therapy in managing paediatric mechanical neck pain.

    We reviewed 42 cases of deep neck abscess drained surgically or treated conservatively between February 2001 and August 2008, based on age, gender, primary focus, main symptom, abscess location, systemic disease, pathogenic bacteria, hospital treatment, hospitalization length, complications and long-term hospitalization. Of the 42, 26 were men and 16 women aged 14 to 80 (central age: 54.5 years). Abscess was caused most by tonsil inflammation (38.1%). Main symptom were sore throat (54.8%) and neck swelling (35.7%). Abscesses were found in the supra- and infrahyoid region in 30 cases and extended to the mediastinum in 2. Of the 42, 14 (33.3%) had hypertension and 11 (26.2%) diabetes mellitus (DM). Inflammation was due to aerobic bacteria (mainly Streptococcus milleri) in 23 cases (54.8%) and to anaerobic bacteria (mainly Peptostreptococcus) in 11 cases (26.2%). Flexible fiberscopic examination was important in evaluating pharyngeal and laryngeal mucosal disorders and enhanced computed tomography was useful in both diagnosis and postoperative observation. Of the 42, 38 required surgical drainage and 4 were cured using needle aspiration and antibiotics. Of the 38 undergoing surgery-tracheostomy was required in 22. Hospitalization for those with tracheostomy and DM was longer than in those without these factors. Complications included 2 cases each of, mediastinal abscess, sepsis, disseminated intravascular coagulation (DIC), acute renal failure, severe pneumonia, upper digestive tract bleeding and swallowing disorder. Early surgical drainage and intravenous antibiotic administration are thus essential for treating deep neck abscesses. (author)

    2016-07-01

    Full Text Available Background: Bone is the most common organ of involvement in patients with Langerhans cell histiocytosis (LCH, which is often painful and associated with significant morbidity from pathological fractures. Current first-line treatments include chemotherapy and steroids that are effective but often associated with adverse effects, whereas the disease may reactivate despite an initial response to first-line agents. Bisphosphonates are osteoclast inhibitors that have shown to be helpful in treating bone lesions of LCH. To date, there are no large international studies to describe their role in treating bone lesions of LCH. Method: We conducted a multicenter retrospective review of 13 patients with histologically proven LCH, who had received bisphosphonates either at diagnosis or at disease reactivation. Results: Ten patients (77% had a single system bone disease, and 3 (23% had bone lesions as part of multisystem disease. Median follow-up time post-bisphosphonate therapy was 4.6 years (range, 0.8 to 8.2 years. Treatment with bisphosphonates was associated with significant pain relief in almost all patients. Twelve  (92% achieved resolution of active bone lesions, and 10 out of them had no active disease for a median of 3.5 years (range, 0.8 to 5 years. One patient did not respond. No major adverse effects were reported in this series.  Conclusion: Bisphosphonates are well-tolerated drugs that can significantly improve bone pain and induce remission in active bone LCH. Future prospective studies evaluating the role of bisphosphonates in LCH are warranted.

  4. Peritoneal dialysis peritonitis by anaerobic pathogens: a retrospective case series

    Science.gov (United States)

    2013-01-01

    Background Bacterial infections account for most peritoneal dialysis (PD)-associated peritonitis episodes. However, anaerobic PD peritonitis is extremely rare and intuitively associated with intra-abdominal lesions. In this study, we examined the clinical characteristics of PD patients who developed anaerobic peritonitis. Methods We retrospectively identified all anaerobic PD peritonitis episodes from a prospectively collected PD registry at a single center between 1990 and 2010. Only patients receiving more than 3 months of PD were enrolled. We analyzed clinical features as well as outcomes of anaerobic PD peritonitis patients. Results Among 6 patients, 10 episodes of PD-associated peritonitis were caused by anaerobic pathogens (1.59% of all peritonitis episodes during study the period), in which the cultures from 5 episodes had mixed growth. Bacteroides fragilis was the most common species identified (4 isolates). Only 3 episodes were associated with gastrointestinal lesions, and 4 episodes were related to a break in sterility during exchange procedures. All anaerobic pathogens were susceptible to clindamycin and metronidazole, but penicillin resistance was noted in 4 isolates. Ampicillin/sulbactam resistance was found in 2 isolates. In 5 episodes, a primary response was achieved using the first-generation cephalosporin and ceftazidime or aminoglycoside. In 3 episodes, the first-generation cephalosporin was replaced with aminoglycosides. Tenckhoff catheter removal was necessary in 2 episodes. Only one episode ended with mortality (due to a perforated bowel). Conclusion Anaerobic PD-associated peritonitis might be predominantly caused by contamination, rather than intra-abdominal events. Half of anaerobic PD-associated peritonitis episodes had polymicrobial growth. The overall outcome of anaerobic peritonitis is fair, with a high catheter survival rate. PMID:23705895

  5. A retrospective case-control study of hepatitis C virus infection and oral lichen planus in Japan: association study with mutations in the core and NS5A region of hepatitis C virus

    Science.gov (United States)

    2012-01-01

    Background The aims of this study were to assess the prevalence of hepatitis C virus (HCV) infection in Japanese patients with oral lichen planus and identify the impact of amino acid (aa) substitutions in the HCV core region and IFN-sensitivity-determining region (ISDR) of nonstructural protein 5A (NS5A) associated with lichen planus. Methods In this retrospective study, 59 patients (group 1-A) with oral lichen planus among 226 consecutive patients who visited our hospital and 85 individuals (group 1-B, controls) with normal oral mucosa were investigated for the presence of liver disease and HCV infection. Risk factors for the presence of oral lichen planus were assessed by logistic regression analysis. We compared aa substitutions in the HCV core region (70 and/or 91) and ISDR of NS5A of 12 patients with oral lichen planus (group 2-A) and 7 patients who did not have oral lichen planus (group 2-B) among patients (high viral loads, genotype 1b) who received interferon (IFN) therapy in group1-A. Results The prevalence of anti-HCV and HCV RNA was 67.80% (40/59) and 59.32% (35/59), respectively, in group 1-A and 31.76% (27/85) and 16.47% (14/85), respectively, in group 1-B. The prevalence of anti-HCV (P oral lichen planus. The adjusted odds ratios for these three factors were 6.58, 3.53 and 2.58, respectively, and each was statistically significant. No significant differences in viral factors, such as aa substitutions in the core region and ISDR of NS5A, were detected between the two groups (groups 2-A and -B). Conclusion We observed a high prevalence of HCV infection in patients with oral lichen planus. Longstanding HCV infection, hypoalbuminemia, and smoking were significant risk factors for the presence of oral lichen planus in patients. It is advisable for Japanese patients with lichen planus to be tested for HCV infection during medical examination. PMID:22490000

    To evaluate the outcome and the potential prognostic factors of apical microsurgery. The teeth with persistent periapical diseases were treated by microsurgery using micro instruments, ultrasonic retrotips and mineral trioxide aggregate (MTA) under dental operate microscope. The procedure includes incision and flap retraction, osteotomy, apicoectomy, retro- preparation and retro- filling of root canal. Patients were recalled at 1, 3, 6, and 12- month intervals. The outcome was evaluated by clinical and radiographic examinations, and the potential prognostic factors were analyzed. One hundred and eighty cases (240 teeth), including 132 upper anterior teeth, 22 lower anterior teeth, 31 upper premolars, 18 lower premolars, 19 upper molars and 18 lower molars, were treated by microsurgery between July 2010 and December 2012. A total of 152 cases (207 teeth) were recalled. The application of the apical microsurgery included failure of previous endodontic treatment, periapical lesion with post, periapical cyst, calcified canals, separated instruments, overfilling, open apex, root facture, failure of previous apical surgery, apical fenestration, and special root canal system. The success rate was 90.8% (188/207). Age, sex, tooth position, type of periapical radiolucency, fistula and clinical application type appeared to have a negative effect on the outcome. Endo-perio lesion was a significant factor. Eighteen cases (19 teeth) failed mainly because of periodontally involved lesion and vertical root fracture. Apical microsurgery, which combines the magnification and illumination provided by the microscope with the proper use of micro instruments, can treat the teeth with persistent periapical diseases precisely and less traumatically with high success rate. Case selection and standardized operations play a key role for success.

    The only available data about tuberculosis (TB) among adolescents date back to the 1980s, although the incidence of tuberculosis has been increasing in this age group. Medical records were reviewed for all adolescents aged 12 to 18 years hospitalized with the diagnosis of TB in Avicenne/Jean Verdier Teaching hospital (Seine-Saint-Denis, suburb of Paris) between September 2000 and December 2004. Of the 52 patients identified, 52% were female. Median age at diagnosis was 15 years (range, 12-18 years). The proportion of adolescents known to be born abroad was 90%. Diagnoses resulted from the examination of a sick child in 79% of cases, a case contact investigation of an adult suspected of having TB in 19% and routine tuberculin skin test in 2%. Twenty-seven of 52 patients (52%) had isolated pulmonary disease. Sixteen patients (31%) had pulmonary and extrapulmonary TB and 8 cases (17%) had exclusively extrapulmonary disease. The site of extrapulmonary TB included pleural (n = 8), meningitis (n = 4), lymph node (n = 4), peritoneal (n = 5), osteoarticular (n = 3) and genitourinary (n = 1). TB was confirmed by the isolation of Mycobacterium tuberculosis from sputum (n = 21), gastric aspirate (n = 8), bone (n = 1) or cerebrospinal fluid (n = 2). No case had a relapse or recurrence of disease in median 3.2 years of follow up. Our results indicate that demographic and clinical characteristics of adolescents with TB differed from adults and children. A specific approach to the prevention and treatment of TB in adolescents is absolutely necessary.

    To determine the etiologic factors, circumstances of diagnosis, obstetrical management and complications of face presentation and to value the maternal and foetal prognosis of this presentation. Thirty-two cases of face presentation have been observed in the maternity wards of Reims and Troyes over the last 12 years. The incidence of face presentation was 0.7 per 1000 deliveries. Spontaneous vaginal delivery occurred with mento-anterior presentation 73% of the time and caesarean section was performed in 100% of mento-posterior presentation. There was no increasing rate of foetal or maternal mortality and morbidity with vaginal delivery. Face presentation is an unusual complication of pregnancy with obstetric factors that predispose the foetus to face presentation. The low foetal and maternal mortality and morbidity substantiate the effectiveness of conservative management in face presentation.

    Decades of research have established only a few etiological factors for glioma, which is a rare and highly fatal brain cancer. Common methodological challenges among glioma studies include small sample sizes, heterogeneity of tumor subtypes, and retrospective exposure assessment. Here, we briefly...... describe the Glioma International Case-Control (GICC) Study (recruitment, 2010-2013), a study being conducted by the Genetic Epidemiology of Glioma International Consortium that integrates data from multiple data collection sites, uses a common protocol and questionnaire, and includes biospecimen...

    Full Text Available Aim: This study aimed to analyze blunt chest trauma cases who were diagnosed with rib fracture and to examine the regional differences likely to appear in trauma cases and treatment approaches. Material and Method: 513 cases who applied to the Emergency Service and Department of Thoracic Surgery between October 2013 and December 2014 due to blunt trauma and were diagnosed with rib fracture were retrospectively examined. The cases were evaluated in terms of etiological factors, thoracic, and other system injuries accompanying the rib fracture, prognosis, and the treatments applied. Results: Isolated rib fracture was present in 266 of the cases. Thoracic organ injuries such as pneumothorax, hemothorax, hemopneumothorax, lung contusion, or laceration and sternal fracture accompanying the rib fracture were present in 247 of the cases. While one or two rib fractures were detected in 298 cases, six or more rib fractures were present in 28 cases. 78.2% of hemothorax cases, 85.3% of pneumothorax cases, 95.4% of hemopneumothorax cases, 81.8% of bilateral pneumothorax cases, 26% of bilateral hemothorax cases, and 71.4% of bilateral hemopneumothorax cases were treated by applying tube thoracostomy. 129 cases diagnosed with thoracic organ injury in addition to rib fracture but not subjected to surgical intervention, and 266 cases diagnosed with isolated rib fracture were discharged with full recovery after appropriate medical treatment. Discussion: Most of the rib fractures occurring due to blunt trauma are treated successfully with medical treatments and conservative approaches and do not need advanced surgical treatments.

    Objective: literature review and case histories. Neuroendocrine tumors (Nets) are considered rare and comprise a group very heterogeneous with different prognosis and evolution. They represent less than 1% of all malignant tumors and most originate from the gastrointestinal tract in enterocromoafines cells are widely distributed in the same: in the stomach, duodenum, pancreas, small, colon and rectum. Carcinoid tumors Gastrointestinal represent over 70% of all tumors (Nets) in humans. And frequently they are finding their debut as disseminated disease, coinciding our review. 21 records were retrospectively analyzed between 1995 and June 2010. No significant difference in gender, of these 9 patients were 12 female and male sex. Ages ranged from 36 years to 83 years, with an average of 63 years. The locations were distributed as follows: 6 patients with small bowel tumor, 2 with blind tumor, 2 esophageal tumor , 1 patient with pancreatic tumor, 1 patient with stomach tumor, 2 patients with retroperitoneal disease in which failed to define the primary, 2 patients with tumor in breast, 3 patients with lung tumor, 1 patient with piriform sinus tumor and 1 patient with parotid tumor. Of the 21 patients, only 4 sometime had functional syndrome characterized by diarrhea and flushing. The treatments that received these patients were also very heterogeneous. From these patients, only one died in 2008 and the others are still alive, some in control and other treatment. Because of the number of patients seen and the therapeutic variability the statistical analysis no was done

    The distal radius fracture is the most frequent fracture in the adult patient. The wide spectrum of different types of fracture and the coexisting factors make the choice for the optimal treatment difficult. As an interne quality control we retrospectively evaluated all patients with distal radius fractures treated in 1995 at our institution. The study included 69 adult patients with 71 distal radius fractures. After on average 26 months 58 patients with 59 fractures were clinically and radiologically evaluated. The patients were asked to give supplementary information about their follow-up treatment as well as any remaining physical difficulties and limitations in the daily life. All x-rays of the broken radius were carefully analysed and compared with the opposite side. The final results were evaluated according to the "Demerit Point System". Patients were treated with five different therapeutical methods. 76.3% of the patients showed a very good/good final result. In 56.7% of the cases secondary fracture dislocation occurred; the dislocation-rate of fractures treated with percutaneous k-wires was 93.3%! A clear correlation between secondary displacement and final results was found. A main factor for an optimal outcome is the anatomic restoration of length and axis of the distal radius as well as of joint congruency, also moderate angular deformities are well tolerated. Our collective showed an unexpected high rate of secondary displacement, especially in the k-wire group. The reasons for this unsatisfactory event are manifold: too optimistic indication, insufficient follow-up examination in the first four to six weeks, inconsequent change to a more stable fixation method in case of a secondary dislocation. The results of this retrospective evaluation had a major impact on our concept of treatment. The dorso-radial double-plate technique combined with bone graft will be more used in the future especially in younger patients. The new standardised concept is the

    Hamstring muscle deficiency is increasingly recognized as a risk factor for anterior cruciate ligament (ACL) tears. The purpose of this study is to evaluate the vastus medialis to semimembranosus cross-sectional area (VM:SM CSA) ratio on magnetic resonance imaging (MRI) in patients with ACL tears compared to controls. One hundred knee MRIs of acute ACL tear patients and 100 age-, sex-, and side-matched controls were included. Mechanism of injury, contact versus non-contact, was determined for each ACL tear subject. The VM:SM CSA was measured on individual axial slices with a novel method using image-processing software. One reader measured all 200 knees and the second reader measured 50 knees at random to assess inter-reader variability. The intraclass correlation coefficient (ICC) was calculated to evaluate for correlation between readers. T-tests were performed to evaluate for differences in VM:SM CSA ratios between the ACL tear group and control group. The ICC for agreement between the two readers was 0.991 (95% confidence interval 0.984-0.995). Acute ACL tear patients have an increased VM:SM CSA ratio compared to controls (1.44 vs. 1.28; p = 0.005). Non-contact acute ACL tear patients have an increased VM:SM CSA ratio compared to controls (1.48 vs. 1.20; p = 0.003), whereas contact acute ACL tear patients do not (1.23 vs. 1.26; p = 0.762). Acute non-contact ACL tears are associated with increased VM:SM CSA ratios, which may imply a relative deficiency in hamstring strength. This study also demonstrates a novel method of measuring the relative CSA of muscles on MRI.

    A retrospective naturalistic case note study to determine the frequency, co-morbidity and treatment-response of body dysmorphic disorder (BDD). Records from 280 patients attending a highly specialised obsessive-compulsive disorder (OCD)/BDD service were analysed. The clinical outcome was measured either through scoring of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) for OCD/BDD, or textual analysis of case notes for evidence of symptomatic improvement, treatment tolerability, and premature disengagement. A total of 32 patients (11.43%) were diagnosed with BDD. Of these, 28 (87.5%) had at least one co-morbidity. All patients were offered cognitive behavioural therapy (CBT) and selective serotonin reuptake inhibitor (SSRI). Adjunctive low-dose antipsychotic was prescribed for 21 (66%) patients. Overall, 18/32 (56%) responded, and 7/32 (22%) disengaged prematurely. Patients offered antipsychotic, SSRI and CBT (n = 21) were compared with those offered SSRI and CBT only (n = 11). The treatment was well-tolerated. Whereas there was no significant inter-group difference in the clinical response rate, premature disengagement occurred less frequently in the antipsychotic-treated patients (9.5% versus 45%; Fisher's Exact Test P = 0.0318). BDD frequently presents with co-morbidity, treatment-resistance and premature disengagement. Adjunctive antipsychotic was associated with significantly better treatment adherence, but responder rates did not differ significantly, possibly related to the small sample-size. A well-powered randomised controlled study is warranted, to determine clinical outcomes with adjunctive antipsychotic in BDD.

In this work we analyze the different policy changes, the drivers of changes and key factors influencing the effectiveness of policies in these three stages.

    Unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC) are benign cystic lesions of bone which are easily diagnosed. However, unusual locations may lead to a false diagnosis. Therefore the aim of this retrospective study was to determine the frequency of unusual localizations. The authors studied 451 cases with histopathologically confirmed diagnosis of UBC or ABC, seen between 1981 and 2012. In the UBC group (352 cases) humerus, femur and calcaneus were found to be the most common sites, while acetabulum, scapula, scaphoid, lunatum, metacarpals, metatarsals, toe phalanges and ulna each accounted for less than 1%. In the ABC group (99 cases) the most common sites of involvement were femur, humerus and tibia, while finger phalanges, ilium, acetabulum, pubis, calcaneus, cuboid, and toe phalanges each accounted for only 1%. The differential diagnosis of cystic bone lesions should include both UBC and ABC. Pain complaints plead for the latter, except in case of fracture.

    To evaluate in retrospect the response to therapy and long-term evolution of a series of primitive intestinal lymphomas. The series was comprised of 42 patients diagnosed in our hospital during 1960-1962. The mean age was 34.5 years (range, 3-73), the M/F ratio was 21/21, and the histopathology distributes as follows: high grade (HG), 24 cases, low grade (LG), 12 cases, and mixed (LG/HG), 6 cases. B/T immunophenotype: 40/2. Staging: IE1,29 cases, IIE2-IV, 11 cases. The treatment applied in the series was classified in various types: ample surgical resection (aSR), 21 cases; partial surgical resection (pSR), 9 cases; abdominal radiation therapy (RT), 7 cases; monochemotherapy (MCT), 7 cases, and polychemotherapy (PCT), 28 cases. The correlation of clinicobiological variables with immediate response to treatment was evaluated by means of the chi square test, and the acturial post-therapeutic survival curves in accordance to the life tables, differences being calculated by the log rank test. Small intestine was the commonest site of involvement, 31 cases; ileocecal region, 7 cases; colon, 2 cases, and colon plus small intestine, 2 cases. Regardless of therapy type, complete remission (CR) was attained in 20 patients (47.5%), partial remission in 5; 11 cases were unresponsive (26.5%) and early death occurred in 6 instances (14.2%). The acturial post-therapeutic survival offered an 8-year expectancy of 47%. The correlation between immediate complete response and 16 clinico-biologic variables showed favourable significance for tumoral proliferation index (i.e., Pc10-positive cells studies. 2) Female sex, type of therapy, multifocal involvement, the need of emergency surgery and high LDH levels have significant value in univariate analyses.

    The purpose of this retrospective case series was to report on the clinical performance of implant-assisted removable partial dentures (IARPDs) with Locator abutments in different partial edentulism situations, with a mean follow-up period of 28.6 months. Twelve consecutive patients were treated with IARPDs. A total of 24 implants were placed in the edentulous area. Minimum follow-up period was 12 months. Overall patient satisfaction, health of peri-implant tissues, survival of implants and abutments, and prosthetic complications were reported. Overall implant survival was 91.6%; two implants failed. No major complications were reported-only one IARPD metal framework broke. No Locator abutment loosening was reported. Within the limitations of this retrospective study, treatment with IARPDs can improve the patient's function, phonetics, and esthetics without the need for extensive bone regeneration surgeries and prosthodontic rehabilitations. However, well-designed prospective clinical studies on IARPDs are needed to support their long-term use.

    Dissociative disorders present a huge challenge in clinical settings. In contrast to other dissociative symptoms, dissociative sensibility disorders are rarely focused on. To identify the clinical characteristics and outcomes of dissociative sensibility disorders in children and adolescents, and to review the use of diagnostic procedures. For the review, a literature search used Pubmed, Embase, Web of Science, and PubPsych (to 02/2015) and the reference lists of the studies identified. Screening of titles and abstracts; full-text assessment by two reviewers. The original case series was identified by using the local data register. Two reviewers independently reviewed the data and, if they agreed on the relevance, extracted the data. In the original case series, data were extracted retrospectively from the records. Sixteen studies and seven case reports were identified, including 931 cases with dissociative disorders. In 210 cases the patient suffered either from a single sensibility disorder or predominantly from sensibility disorders. We identified thirteen further cases in our cohort. In both groups there was female predominance; the mean age of manifestation was early adolescence. The timing of admissions was variable. In approximately 50% of cases a premorbid stressful life event could be identified. Over 75% of cases had a good prognosis with complete resolution. Retrospective character of our own data collection, partially missing differentiation between the subgroups of dissociative disorders in the reviewed studies. There is no uniform procedure for diagnostic work-up. The overall short-term prognosis is good. Copyright © 2017 European Paediatric Neurology Society. Published by Elsevier Ltd.

    Full Text Available Aim: Our aim was to evaluate the properties of pediatric forensic cases and to discuss the precautions in order to prevent the occurrence of these forensic events. Methods: The patient files and forensic reports of pediatric (age 0-18 years forensic cases, who were referred to the emergency department in our hospital between January 01, 2009 and December 31, 2011 were retrospectively investigated. Results: A total of 421 forensic pediatric cases with a median age of 9.9±5.5 years were included in the study. Off the cases, 61% (n=257 were male and 47.3% were in 5-14 age group. The type of the events were traffic accident (50.4%, fall (18.3%, stab injuries (10.9%, intoxication (5.9%, pounding (5.0% and other incidents (9.5%. There were nine cases of suicide attempt (all of them were above 14 years of age and four cases of physical abuse (three of them were under 15 years of age. After the observation period, 79.8% of the cases were discharged from the emergency department, whilst 20.2% of cases were hospitalized in one of the clinics. Conclusion: Because most of the cases were traffic accident, this situation show us that these injuries are preventable. Prevention and intervention strategies should be developed for providing a safe environment for children.

    Erythropoiesis stimulating agents [erythropoietin (EPO)] have been recommended to treat anaemic patients who cannot receive or refuse blood tranfusion ('untransfusable' patients). The objective of the study was to quantify the association of EPO use with haemoglobin (Hgb) recovery in anaemic untransfusable hospitalised patients. EPO treated anaemic untransfusable patients were identified through the combination of a retrospective case review and a systematic review of the medical literature. Literature reports of untransfusable patients not treated with any EPO were used as a comparator group. Hgb concentrations before and following EPO use were abstracted and used to determine the rate of Hgb recovery for each case. Multilevel mixed effects modelling was used to determine the association of Hgb recovery with EPO use. A total of 76 EPO treated cases (19 cases from the retrospective hospital case review and 57 from the literature), and 33 non-EPO treated comparator patients from the literature were included in the study. Hgb increased similarly over time in all groups at an overall mean standard error (SE) rate of 0·13 (0·01) g dL(-1)  day(-1) . The Hgb recovery rate was higher in patients with lower baseline Hgb, regardless of EPO use. No association was found between the rate of Hgb recovery and EPO use, dose or therapy duration. In anaemic, 'untransfusable' hospitalised patients, EPO use was not associated with increased Hgb recovery at anytime within 28 days. © 2014 The Authors.

    Aspergillus spp. are saprophytic opportunistic fungal organisms and are a common cause of otomycosis in humans. Although there have been case reports of Aspergillus otitis externa in dogs, to the best of the authors' knowledge, this is the first retrospective case series describing Aspergillus otitis in dogs and cats. To characterize signalment, putative risk factors, treatments and outcomes of a case series of dogs and cats with Aspergillus otitis. Eight dogs and nine cats diagnosed with Aspergillus otitis. A retrospective review of medical records from 1989 to 2014 identified animals diagnosed with Aspergillus otitis based on culture. All dogs weighed greater than 23 kg. The most common putative risk factors identified in this study were concurrent diseases, therapy causing immunosuppression or a history of an otic foreign body. Aspergillus otitis was unilateral in all study dogs and most cats. Concurrent otitis media was confirmed in three dogs and one cat, and suspected in two additional cats. Aspergillus fumigatus was the most common isolate overall and was the dominant isolate in cats. Aspergillus niger and A. terreus were more commonly isolated from dogs. Animals received various topical and systemic antifungal medications; however, otic lavage under anaesthesia and/or surgical intervention increased the likelihood of resolution of the fungal infection. Aspergillus otitis is uncommon, typically seen as unilateral otitis externa in cats and larger breed dogs with possible risk factors that include immunosuppression and otic foreign bodies; previous antibiotic usage was common. © 2015 ESVD and ACVD.

    Full Text Available Paracoccidioidomycosis (PCM is a systemic mycosis caused by the fungus Paracoccidioides brasiliensis and is endemic to Brazil. The aim of this study was to perform a retrospective analysis of the PCM cases in the countryside south of Rio Grande do Sul, Brazil. The files from four histopathology laboratories located in the city of Pelotas were obtained, and all of the epidemiological and clinical data from the PCM diagnosed cases were collected for analysis. A total of 123 PCM cases diagnosed between 1966 and 2009 were selected. Of these patients, 104 (84.5% were male, and 17 were female. The patients ranged from 02 to 92 years of age. Fifty-two cases (41.9% were obtained from the oral pathology laboratory, and the remaining 71 cases (58.1% were obtained from the three general pathology laboratories. Of all of the patients studied, 65.2% lived in rural zones and worked in agriculture or other related fields. Data on the evolution of this disease was available for 43 cases, and the time frame ranged from 20 to 2920 days (mean = 572.3 days. An accurate diagnosis performed in less than 30 days only occurred in 21% of the cases. PCM is endemic to the countryside of Rio Grande do Sul. Therefore, it is recommended that PCM be included as a differential diagnosis, mainly for individuals between 30 and 60 years of age, living in rural zones and who have respiratory signs and associated-oropharyngeal lesions.

    Typhoid fever is a systemic illness which in high-income countries mainly affects travellers. The incidence is particularly high on the Indian subcontinent. Travellers who visit friends and relatives (VFR) have been shown to have a different risk profile than others. We wished to identify main characteristics for travellers infected with S. Typhi considering both clinical and laboratory findings in order to provide for faster and better diagnostics in the future. The outcome of treatment, especially concerning relapse, was evaluated as well. Retrospectively collected data from 19 adult cases of typhoid fever over a 5-year period at the Department of Infectious Diseases, Copenhagen University Hospital, Hvidovre Denmark. The patients were young adults, presenting with symptoms within a month after travelling. 84% were returned from travelling in the Indian subcontinent. 17 out of 19 patients were VFR-travellers. The main symptoms were fever (100%), gastrointestinal symptoms (84%), headache (58%) and dry cough (26%). Laboratory findings showed elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH) in all cases and elevated alanine transaminase (ALAT) in 47% of cases. In primary cases 4 isolates were fully susceptible to ciprofloxacin, the remaining were intermediate susceptible. Relapse occurred in 37% of the cases and only in cases where the patient was infected by a strain with intermediate susceptibility. Better pre-travel counselling should be given to VFR-travellers. The main symptoms and laboratory findings confirm previous findings. The relapse rate was unexpected high and could be correlated to ciprofloxacin-resistance.

    This study assessed the epidemiological characteristics and management of the permanent teeth avulsion cases attended in a Brazilian dental trauma service from December 2005 to August 2016. A retrospective study was conducted of case records of 93 patients involving 139 avulsed teeth. Data included sex, age, trauma etiology, location of the accident, number and position of avulsed teeth, and presence and type of associated traumatic lesions. Management of the avulsed teeth was addressed as: time elapsed until teeth were retrieved from the accident's location; teeth's cleaning method and storage media; time elapsed until seeking treatment and replantation. The majority of the patients were children from 6-10 (31.2%) and 11-15 years old (26.9%). Male patients were more affected than female. Bicycle accident was the main etiological factor (31.2%). In 56 (60.2%) cases, traumatic lesions to neighboring teeth were present. In 55 (59.1%) cases, lesions to adjacent soft tissues were reported. In 82 (88.2%) cases, patients requested treatment at the same day of the accident. Sixty-four teeth (46.0%) were immediately retrieved and 28 (20.1%) were not found. Forty-two teeth (30.2%) were kept dry. Only one tooth (0.7%) was immediately replanted at the accident's site, while 51 teeth (36.7%) were not replanted. Numerous avulsed teeth were inappropriately managed and immediate replantation was not frequent. Public policies must be created to raise awareness towards the particularities of avulsion cases.

    Full Text Available Objective: Knowledge concerning treatment and care of hand lesions is often based on small case series, case reports and a few large general case series. The aim of this study is to present our experience with hand tumors’ and tumor-like lesions’ incidence, age range and localizations. Material and Method: Between 2006-2016, 402 patients operated and histopathologically diagnosed with bone and soft tissue tumorous conditions of the hand were evaluated retrospectively. Results: Three hundred sixty one out of 402 cases (89.8% were soft tissue tumors and 41 cases (10.2% were osseous tumors of the hand. A total of 10 malignant tumors (2.5% were encountered in the hand. The average age of the patients was 41.9 years (ranged from 1 to 83 years. Among 361 soft tissue tumors, only 6 cases (1.6% were malignant and they were squamous cell tumors (n=5 and synovial sarcoma (n=1. The most common soft tissue pathology was ganglion cyst (n=125. The most common bone tumor was enchondroma, diagnosed in 26 patients (6.4% of all patients. Primary malignant bone tumors were extremely rare in the hand; one osteosarcoma and one chondrosarcoma were reported. Metastatic tumors to the hand were seen in two patients; and they were lung carcinoma and chondrosarcoma metastasis. Conclusion: Up-date knowledge and a thorough understanding of the nature and demographic characteristics of the tumorous conditions of the hand are crucial for accurate diagnosis and appropriate treatment.

    To establish distribution frequency and demographic characteristics of salivary gland tumours (SGT) in order to identify possible risk profiles. The present report constitutes an eight year retrospective study (January 2000-August 2007). The archives of the Clinical and Experimental Pathology Laboratory (Graduate and Research Division, Dental School, National Autonomous University of Mexico) as well as archives of the Surgical Pathology Service (General Hospital, Mexico City) were subject to revision in order to select all cases where SGT tumour diagnoses were emitted. Age and gender of patients as well as SGT topography were obtained from medical records. Selected cases were classified according to location of the lesion, histological lineage and biological behaviour. 360 cases of SGT were included, 227 (67%) cases were benign tumours, while 83 cases (23%) were malignant tumours. SGT were most frequent in women with ages ranging from their 3rd to 5th decades of life. 275 tumours were located in major salivary glands, 78.9% of them were identified in the parotid gland. The most frequent location of tumours arising from minor salivary glands (33 cases, 38%) was found in the palatine glands. Tumours of epithelial lineage were the predominant histological type. The most frequent benign tumours were pleomorphic adenomas (86.1%) and papillary cystadenoma lymphomatosum (7.3%). The most frequent malignant tumours were adenoid cystic carcinomas (25%) and mucoepidermoid carcinomas (23.6%). Salivary gland tumours in Mexican population appear principally in major salivary glands of women in their 3rd to 5th decade of life.

    Postoperative hematoma is a rare and dangerous complication of cervical spine surgery. The aim of this study was to investigate the incidence and related factors of postoperative hematoma, and to report on 15 cases at our institution over a 6-year period. Fifteen cases of postoperative hematoma were retrospectively identified. We investigated their neurological outcomes, characteristics, and surgical data, and identified risk factors associated with postoperative (PO) hematoma. Patients with hematoma were compared to those with no hematoma, in order to identify risk factors. Retropharyngeal hematomas developed in seven cases and epidural hematomas in eight. The total incidence of postoperative hematoma was 1.2%: 0.5% retropharyngeal hematomas and 0.6% spinal epidural hematomas. At time of onset, the severity of paralysis was assessed as grade B in one case, grade C in six cases, and grade D in eight cases. Risk factors for PO hematoma were: (1) presence of ossification of the posterior longitudinal ligament (OPLL) (Phematoma group and non-hematoma group (P>0.05). Precise preoperative preparation and systematic evaluation are central to successful management of PO hematoma after anterior cervical surgery. Risk factors for PO hematoma include multilevel decompression, OPLL, higher BMI, and longer operation time. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    Full Text Available BACKGROUND: Health services for victims of rape are recognised as a particularly neglected area of the health sector internationally. Efforts to strengthen these services need to be guided by clinical research. Expert medical evidence is widely used in rape cases, but its contribution to the progress of legal cases is unclear. Only three studies have found an association between documented bodily injuries and convictions in rape cases. This article aims to describe the processing of rape cases by South African police and courts, and the association between documented injuries and DNA and case progression through the criminal justice system. METHODS AND FINDINGS: We analysed a provincially representative sample of 2,068 attempted and completed rape cases reported to 70 randomly selected Gauteng province police stations in 2003. Data sheets were completed from the police dockets and available medical examination forms were copied. 1,547 cases of rape had medical examinations and available forms and were analysed, which was at least 85% of the proportion of the sample having a medical examination. We present logistic regression models of the association between whether a trial started and whether the accused was found guilty and the medico-legal findings for adult and child rapes. Half the suspects were arrested (n = 771, 14% (209 of cases went to trial, and in 3% (31 of adults and 7% (44 of children there was a conviction. A report on DNA was available in 1.4% (22 of cases, but the presence or absence of injuries were documented in all cases. Documented injuries were not associated with arrest, but they were associated with children's cases (but not adult's going to trial (adjusted odds ratio [AOR] for having genital and nongenital injuries 5.83, 95% confidence interval [CI] 1.87-18.13, p = 0.003.

    To describe the clinical characteristics of recurrent septic peritonitis in dogs. Multicenter retrospective observational study. Client-owned dogs with recurrent septic peritonitis. Three university emergency and referral hospitals. None. Medical records from 3 veterinary university teaching hospitals were reviewed and data were collected using a standardized data collection sheet for all cases of septic peritonitis during the study period (2000-2011). Forty one dogs met the inclusion criteria for recurrent peritonitis. All dogs underwent relaparotomy. The original cause of septic peritonitis in these cases included previous surgery for gastrointestinal foreign body removal (n = 26), gastrointestinal neoplasia (n = 3), gastric or duodenal ulceration (n = 3), biliary tract leakage (n = 2), and single instance for each of the following: penetrating foreign body, hernia strangulation, intussusception, mesenteric volvulus, infection of the laparotomy incision, prostatic abscess, and trauma. Eighteen animals survived to discharge. There was no difference detected between survivors and nonsurvivors with recurrent peritonitis in terms of inciting cause, serum albumin concentration, surgical management, or provision of appropriate initial antimicrobials. The survival rate for dogs having recurrent peritonitis was 43.9% (18/41 dogs). This retrospective study did not identify any significant prognostic indicators for dogs with recurrent peritonitis and that the mortality rate for dogs having more than one surgery for septic peritonitis is similar to that reported for a single surgery for septic peritonitis. ©Veterinary Emergency and Critical Care Society 2015.

    The paper will discuss the LHC control system performance during 2016 operation. It aims to answer the following questions: In retrospect, which controls facilities, if any, were missing and what could be improved? How did we perform on follow-up of requests from Evian 2015? Human errors committed while interacting with the control system are discussed and suggestions made for possible mitigation measures. Looking forward to EYETS (the extended year end technical stop), the planned control system changes and their impact will be presented.

    Lyme disease is the result of Borrelia burgdorferi bacterial infection after exposure from a tick bite. A pathognomonic finding in early-stage Lyme disease is an expanding, red macular ring known as erythema migrans. Lyme arthritis is a late-stage manifestation of this disease, affecting the large, weightbearing joints with intermittent pain and swelling. The existing data on Lyme disease and subsequent arthritis have reported manifestations in the lower extremity, primarily in the knee and ankle and less commonly the small joints of the foot. We present a retrospective case series of 11 cases of painful arthritis in the foot and ankle with confirmatory Lyme disease testing. Copyright © 2015 American College of Foot and Ankle Surgeons.

    Maxillofacial fractures are encountered less commonly during childhood period due to anatomic, social, cultural, and environmental factors. Although the incidence of all maxillofacial fractures is 1% to 15% among pediatric and adolescent patients, this rate drops to less than 1% in children below 5 years age. Two hundred thirty-five cases (mandibular fracture were evaluated retrospectively. Patients records were examined in terms of age, gender, cause of fracture, fracture localization, number of fractures, fracture pattern, accompanying injuries, applied treatment methods, and complications. Mean age of cases was 9.2 years and 165 cases were male, 70 were female. Traffic accidents as the most common etiologic cause in all ages. Falls is the second most common cause which particularly affects children above age of 2 years. All cases had 333 fractures and the most common fracture localization was parasymphysis region (34%). The other most common fracture localizations were as follows: condyle (19%), corpus (13%), dentoalveolar region (12%), angulus (11%), symphysis region (9%), and ramus (2%). There was only a single fracture line in 145 cases, 40 cases had unilateral multiple and 50 cases had bilateral fracture lines. We applied symptomatic (conservative) treatment in 20 (8%) of our cases; fracture fixation with interdental wires or closed reduction methods were employed in 122 patients. Internal fixation with open reduction (OR) was performed on 51 (22%) patients. Both closed and OR techniques were carried out in 30 (13%) patients. Pediatric mandibular fractures, which are seen less frequently compared with those of adults, require a specific and different treatment. Although mostly less invasive methods are preferred, we believe that ORs should be considered when required.

    The purpose of this case series is to describe the chiropractic management of 21 patients with daily stress and occasional total urinary incontinence (UI). Twenty-one case files of patients 13 to 90 years of age with UI from a chiropractic clinic were reviewed. The patients had a 4-month to 49-year history of UI and associated muscle dysfunction and low back and/or pelvic pain. Eighteen wore an incontinence pad throughout the day and night at the time of their appointments because of unpredictable UI. Patients were evaluated for muscle impairments in the lumbar spine, pelvis, and pelvic floor and low back and/or hip pain. Positive manual muscle test results of the pelvis, lumbar spine muscles, and pelvic floor muscles were the most common findings. Lumbosacral dysfunction was found in 13 of the cases with pain provocation tests (applied kinesiology sensorimotor challenge); in 8 cases, this sensorimotor challenge was absent. Chiropractic manipulative therapy and soft tissue treatment addressed the soft tissue and articular dysfunctions. Chiropractic manipulative therapy involved high-velocity, low-amplitude manipulation; Cox flexion distraction manipulation; and/or use of a percussion instrument for the treatment of myofascial trigger points. Urinary incontinence symptoms resolved in 10 patients, considerably improved in 7 cases, and slightly improved in 4 cases. Periodic follow-up examinations for the past 6 years, and no less than 2 years, indicate that for each participant in this case-series report, the improvements of UI remained stable. The patients reported in this retrospective case series showed improvement in UI symptoms that persisted over time.

    Full Text Available This longitudinal cross-sectional clinical study investigated the incidence of sialorrhoea in dogs with spirocercosis and determined whether breed, body weight and the extent of the oesophageal involvement was associated with this presentation. A retrospective analysis was performed on the medical records of 233 dogs and information pertaining to 65 dogs was collected as part of a prospective study. All the animals were client-owned. Patients from the retrospective study underwent thoracic radiography or oesophageal endoscopy to diagnose and characterise the infection and were placed on therapy with a macrocyclic lactone, whereas the patients in the prospective study had both radiography and endoscopy routinely performed and biopsies of the oesophageal nodules collected where possible. Tru-cut biopsies of affected salivary glands were taken in 10 of 13 patients demonstrating clinical signs of sialorrhoea and salivary gland enlargement. The entire salivary gland was sectioned in an additional three dogs with spirocercosis and no sialorrhoea that were presented for post mortem examination. Sialorrhoea was present in 33/298 cases (11%. Fox terrier breeds were over-represented in the patients with sialorrhoea, comprising 36% of cases, whereas they only comprised 1.5% of the patients without sialorrhoea (p < 0.001, chi squared test and 5% of the combined group. Dogs weighing 12 kg or less were significantly over-represented in the sialorrhoea group, 69% versus 19.5% (p < 0.001, chi square test. Age was not significantly different between the two groups (p < 0.08, Mann-Whitney test. The number of oesophageal nodules per case was significantly higher in the non-sialorrhoea cases (p = 0.048, Mann-Whitney test. The prevalence of distal oesophageal and lower oesophageal sphincter involvement, and neoplastic transformation of the nodules were not statistically different between the two groups. None of the fox terriers in either group showed neoplastic

    Anaplastic thyroid carcinoma (ATC) is a rare tumor, with poorly defined oncogenic molecular mechanisms and limited therapeutic options contributing to its poor prognosis. The aims of this retrospective study were to determine the frequency of anaplastic lymphoma kinase (ALK) translocations and to identify the mutational profile of ATC including TERT promoter mutations. One hundred and forty-four ATC cases were collected from 10 centers that are a part of the national French network for management of refractory thyroid tumors. Fluorescence in situ hybridization analysis for ALK rearrangement was performed on tissue microarrays. A panel of 50 genes using next-generation sequencing and TERT promoter mutations using Sanger sequencing were also screened. Fluorescence in situ hybridization was interpretable for 90 (62.5%) cases. One (1.1%) case was positive for an ALK rearrangement with a borderline threshold (15% positive cells). Next-generation sequencing results were interpretable for 94 (65.3%) cases, and Sanger sequencing (TERT) for 98 (68.1%) cases. A total of 210 mutations (intronic and exonic) were identified. TP53 alterations were the most frequent (54.4%). Forty-three percent harbored a mutation in the (H-K-N)RAS genes, 13.8% a mutation in the BRAF gene (essentially p.V600E), 17% a PI3K-AKT pathway mutation, 6.4% both RAS and PI3K pathway mutations, and 4.3% both TP53 and PTEN mutations. Nearly 10% of the cases showed no mutations of the RAS, PI3K-AKT pathways, or TP53, with mutations of ALK, ATM, APC, CDKN2A, ERBB2, RET, or SMAD4, including mutations not yet described in thyroid tumors. Genes encoding potentially druggable targets included: mutations in the ATM gene in four (4.3%) cases, in ERBB2 in one (1.1%) case, in MET in one (1.1%) case, and in ALK in one (1.1%) case. A TERT promoter alteration was found in 53 (54.0%) cases, including 43 C228T and 10 C250T mutations. Three out of our cases did not harbor mutations in the panel of genes with therapeutic

    A multicenter, retrospective review of C5 palsy after cervical spine surgery. Postoperative C5 palsy is a known complication of cervical decompressive spinal surgery. The goal of this study was to review the incidence, patient characteristics, and outcome of C5 palsy in patients undergoing cervical spine surgery. We conducted a multicenter, retrospective review of 13 946 patients across 21 centers who received cervical spine surgery (levels C2 to C7) between January 1, 2005, and December 31, 2011, inclusive. P values were calculated using 2-sample t test for continuous variables and χ 2 tests or Fisher exact tests for categorical variables. Of the 13 946 cases reviewed, 59 patients experienced a postoperative C5 palsy. The incidence rate across the 21 sites ranged from 0% to 2.5%. At most recent follow-up, 32 patients reported complete resolution of symptoms (54.2%), 15 had symptoms resolve with residual effects (25.4%), 10 patients did not recover (17.0%), and 2 were lost to follow-up (3.4%). C5 palsy occurred in all surgical approaches and across a variety of diagnoses. The majority of patients had full recovery or recovery with residual effects. This study represents the largest series of North American patients reviewed to date.

    Objective: To investigate the effect of the second-stage transcranial and transsphenoidal approach for giant pituitary tumors. Methods: A retrospective review of 21 patients, who had undergone the transcranial surgery and then transsphenoidal surgery for giant pituitary adenomas from 2012 to 2015 in the neurosurgery department of West China Hospital, was performed. Visual findings, endocrine presentation, complications, and tumor types were collected. All data were based on clinical feature, MRI, and follow-up. Results: Among the 21 cases, gross total resection of tumor was achieved in 7 of all patients, subtotal in 11, and partial in 3. No intracranial hemorrhage or death occurred postoperatively. Postoperative infectionoccurred in one patient and cerebrospinal fluid leakage occurred in 3 patients. Four patients recovered after treatment. Conclusion: According to the clinical feature and MRI, it is safe and effective to choose the transcranial surgery and then transsphenoidal surgery for specific giant pituitary adenomas, which can improve treatment effects and reduce postoperative complications.

    The aetiology of status asthmaticus (SA), a complication of severe asthma, is unknown. Fungal exposure, as measured by fungal atopy, is a major risk factor for developing asthma, but the relationship of fungi in SA per se has not previously been reported. In this five patient retrospective case series study, lower respiratory tract cultures were performed on bronchoalveolar lavage or tracheal aspirate fluid, comparing standard clinical laboratory cultures with a specialized technique in which respiratory mucus was removed prior to culture. We show mucolytic treatment allows increased detection of fungal growth, especially yeast, from the lower airways of all SA patients. We also demonstrate that the yeast Candida albicans inhalation readily induces asthma-like disease in mice. Our observations suggest, SA may represent a fungal infectious process, and supports additional prospective studies utilizing anti-fungal therapy to supplement conventional therapy, broad-spectrum antibiotics and high-dose glucocorticoids, which can promote fungal overgrowth.

    Backgrounds: Lichen planus is a chronic systemic disease and oral mucosa is commonly involved. Oral lichen planus (OLP) most commonly affects middle-aged women. The prevalence of the disease ranges between 0.5% and 2.6% in the general population and the range of malignant transformation varies between 0% and 10%. Objectives: To assess the rate of malignant transformation of OLP samples. Materials and Methods: This retrospective study was carried out on 112 medical records of patients with histological diagnosis of OLP who attended the Department of Pathology at the Educational Hospital from 2005 to 2012. H&E-stained slides were reviewed by two pathologists using strict clinical and histopathological diagnostic World Health Organization (WHO) criteria. Dysplastic changes were diagnosed and graded according to the latest WHO classification. Results: Of the 112 cases diagnosed as OLP, there were 39 males and 73 females and the patients’ ages ranged from 15 to 86 years (mean age 44.5 years). The erosive form with fifty cases was the most common clinical type and the papular type with one case was the least common clinical type. Regarding the site, the buccal mucosa was the most common site with 52 cases. Totally, dysplastic changes were found in 12 samples, among them five cases showed mild dysplasia and seven cases showed moderate dysplasia. One case developed oral squamous cell carcinoma after 3 years. Conclusion: OLP is considered as a premalignant condition by the WHO and several authors. Although the malignancy rate is not so high, to reduce morbidity and mortality from cancer arising on OLP lesions, a regular follow-up examination is recommended. PMID:27721603

    Full Text Available Primary central nervous system lymphoma (PCNSL is an infrequent form of non-Hodgkin lymphoma restricted to the CNS. More than 90% are type B and mainly affect patients aged 50-70 years. Immunodeficiency is the most important risk factor. The aim of our study was to evaluate the immune status, clinical presentation and findings in complementary studies of PCNSL patients. A retrospective analysis of 48 cases treated in our center between January 1992 and May 2015 was performed. Median age at diagnosis was 61 years (range 25-84; with male predominance (2.1:1. Forty one cases (85% were immunocompetent patients. Brain MRI findings showed parenchymal involvement in 45 cases (94%, 43% with frontal lobe and 35% basal ganglia, 4% had meningeal involvement and 2% had ophthalmic involvement at diagnosis. Fifty-five percent had restricted signal on diffusion weighted imaging and contrast enhancement was found in 89%. Pyramidal syndrome was the main initial clinical manifestation (56%. There were abnormal findings in 62% of CSF samples, but in only 11.1% positive cytology results were detected. The most frequent type was diffuse large B-cell lymphoma (83%, being B-cell type the most common form between them (96%. In our series PCNSL was more frequent in immunocompetent elderly male subjects. At initial evaluation, clinical manifestations and MRI findings were variable. The initial suspicion of this entity would allow an early diagnosis, avoiding empirical treatments that may confuse or delay diagnosis

    Full Text Available This study was performed to investigate the clinical manifestations, treatment methods, and prognosis of Rosai-Dorfman disease (RDD with laryngeal involvement. Five clinical cases of RDD with laryngeal involvement diagnosed between 1986 and 2015 were retrospectively analyzed. The laryngeal lesions of these 5 patients mostly involved the glottis and subglottis, with the main symptoms being a hoarse voice and airway obstruction. In addition, the patients mostly exhibited a unilateral or asymmetric onset that was manifested by a laryngeal submucosal nodular mass. The patients were subjected to a regimen of hormone treatment combined with surgical resection. The median follow-up duration was 101 months (8–384 months. One case was lost, and the remaining 4 subjects are alive with disease. The follow-up examinations revealed that 4 subjects had stable laryngeal conditions, whereas one showed minor progression. RDD with laryngeal involvement is clinically rare and differs considerably from classical RDD in age of onset, gender composition, and extranodal involvement. The regimen of hormone treatment combined with surgical resection can stabilize the patient’s general condition and laryngeal lesion. Tracheotomies are recommended for patients with dyspnea. After their conditions stabilize, decannulation can be successfully performed in most cases. This therapeutic regimen generally delivers a good prognosis.

    Porcine deltacoronavirus (PDCoV) was first reported in the United States (US) in February 2014. This was the second novel swine enteric coronavirus detected in the US since May 2013. In this study, we conducted retrospective testing of samples submitted to three veterinary diagnostic laboratories where qualifying biological samples were derived from previously submitted diagnostic case submissions from US commercial swine farms with a clinical history of enteric disease or from cases that had been previously tested for transmissible gastroenteritis virus, PEDV, or rotavirus. Overall, 2286 banked samples were tested from 27 States. Samples were collected in 3 separate years and in 17 different months. Test results revealed 4 positive samples, 3 collected in August 2013 and 1 collected in October 2013. In addition, a case series including 42 operations in 10 States was conducted through administration of a survey. Survey data collected included information on characteristics of swine operations that had experienced PDCoV clinical signs. Special emphasis was placed on obtaining descriptive estimates of biosecurity practices and disease status over time of each operation. Clinical signs of PDCoV were reported to be similar to those of PEDV. The average number of animals on each operation exhibiting clinical signs (morbidity) and the average number of case fatalities was greatest for suckling and weaned pigs. Average operation-level weaned pig morbidity was greatest in the first week of the outbreak while average operation-level suckling pig case fatality was greatest in the second week of the outbreak. The survey included questions regarding biosecurity practices for visitors and operation employees; trucks, equipment and drivers; and feed sources. These questions attempted to identify a likely pathway of introduction of PDCoV onto the operations surveyed. Published by Elsevier B.V.

    The aim of this study was to follow patient cases retrospectively in a longitudinal manner from the time of implant placement to the time they were diagnosed with peri-implant disease, and to identify associated clinical and microbiological features of peri-implant disease. A total of 281 patient cases were chosen from the archives of the Oral Microbiological Diagnostic Laboratory, Gothenburg, Sweden, based on bacterial samples taken from diseased implants. A form was designed and filled in separately for each case including data on patient, implant and disease profile. Most cases were severe peri-implantitis cases (91.4%). In 41.3% of the patients, peri-implantitis was developed early, already after having implants in function less than 4 years. The type of implant surface was significantly associated with the time in years implants were in function, before disease was developed (P < 0.05). The microbiological results by both culture and checkerboard analysis, although failed to fully correspond to the severity of the disease in terms of magnitude, proved to show that peri-implantitis is a polymicrobial anaerobic infection with increased number of AGNB (aerobic Gram-negative bacilli) in 18.6% of the patients. Peri-implantitis is a biological complication of implants in function that poses a threat to their long-term survival. It may develop earlier around implants with rough surfaces and it may represent a true infection. Microbiological sampling methods should be improved and uniformed so as to fully unveil the microbiological profile of the disease. © 2011 John Wiley & Sons A/S.

    Although total hip arthroplasty is one of the most common orthopaedic surgical procedures, it remains unclear whether histopathological examination of the excised femoral head adds to the quality of patient care. We propose that assessment of femoral heads resected during total hip arthroplasty and donated for allograft use may provide a profile of femoral head pathology that benefits total hip arthroplasty patients and bone donors. We retrospectively analyzed the histological findings reported for 6161 femoral heads donated for allograft use between 1993 and 2006. Specimens obtained during total hip arthroplasty and specimens donated at death were reviewed. Follow-up investigations that resulted from abnormal histopathological findings were also reviewed. The Western Australian Cancer Registry was used to determine whether patients with a suspected neoplasm were subsequently diagnosed with such a disease. A retrospective review of the histopathological findings was conducted to evaluate and reclassify all previous observations of abnormalities. One hundred and five femoral heads demonstrated abnormal or reactive histopathological features not reported prior to surgery and were rejected for allograft use. A reactive lymphocytic infiltrate, most likely due to osteoarthritis, was the most commonly identified feature (forty-five cases). Other features observed in twenty-seven cases were also most likely due to the presence of severe osteoarthritis. Ten femoral heads demonstrated plasmacytosis, which may have been related to osteoarthritis. Two patients were diagnosed with Paget's disease, and two, with rheumatoid arthritis. Nineteen patients had a suspected neoplasm. Of these nineteen, eight cases of non-Hodgkin's lymphoma or chronic lymphocytic leukemia and one case of myelodysplastic syndrome were confirmed on further investigation. One subsequently confirmed malignancy was detected per 770 femoral heads examined. Our findings indicate that, even with a detailed

    Acupuncture is a promising option in the treatment of functional bowel disorders. The aim of this study was to evaluate the feasibility and acceptance of acupuncture for the treatment of hospital-induced constipation (HIC) in children. Bilateral stimulation of acupuncture point LI11 was applied in 10 children with HIC using fixed indwelling acupuncture needles (0.9 mm long) before considering starting conventional local constipation therapy with laxative suppositories. The clinical records were studied retrospectively for feasibility, acceptance and effectiveness of acupuncture. Acupuncture was feasible in all children and application of the indwelling needles was tolerated without fear. Side effects were not observed. After a median of 3 days of HIC, all children defaecated within 2 h after LI11 stimulation. No patient required conventional local constipation therapy. Acupuncture for the treatment of HIC is feasible and acceptable. Its effect should be verified in a randomised controlled trial.

    We undertook a study on a series of laryngeal sarcoidosis (LS), a very rare and often threatening localization to better specify laryngeal manifestations, sarcoidosis clinical expression and long-term follow-up. This was a retrospective case-control study. All LS patients from two French centers were included and compared to sarcoidosis patients without laryngeal localization with two controls for one patient. Twelve consecutive LS patients were recruited between 1993 and 2011. LS revealed sarcoidosis in eight cases (67%). The most common symptoms were hoarseness (77%), inspiratory dyspnea (38%) and dysphagia (38%). Epidemiological characterisics were not different. Extrapulmonary localizations were significantly more common in LS patients than in controls (92% vs. 54%, p=0.02), particularly lupus pernio (25% vs. 0%, p=0.03) and nasosinusal involvement (83% vs. 4%, p<0.01) while thoracic involvement was less frequent (58% vs 100%, p < 0.01). Treatment rates were higher in the LS group (92% vs. 58%, p=0.04), and treatment duration was longer (median: 81 vs. 13 months, p=0.04), with frequent long-term treatment (67%, N=8/12). Two patients underwent surgery. One patient needed temporary tracheostomy during the course of the disease; Remission rates were lower in LS patients (9% vs. 58% at 2 years p<0.01). Eventually, there was no death nor definitive tracheotomy. LS is a rare condition that is often associated to other loco-regional localizations. LS are often difficult to manage. Survival is good but may require a medico-surgical approach.

    Formerly, Arcanobacterium pyogenes was recently renamed Trueperella pyogenes. This opportunistic bacterium is related to miscellaneous pyogenic infections in animals. Most studies involving T. pyogenes are case reports, whereas few surveys have focused the major aspects of T. pyogenes infections involving a case series study design. The aim of this study was to retrospectively evaluate selected epidemiological and clinical aspects, as well as the in vitro antimicrobial susceptibility pattern of 144 cases of T. pyogenes infections among domestic animals from 2002 to 2012. T. pyogenes was isolated from different clinical specimens from cattle, goats, sheep, pigs, horses, dogs, and buffaloes. Correlations were assessed by the Chi-square or Fisher's exact tests. Mastitis (45.1%), abscesses (18.0%), pneumonia (11.1%), and lymphadenitis (9.0%) were the most common clinical manifestations. In addition, the organism was also isolated from other miscellaneous clinical specimens from cases of septicemia, encephalitis, pyometra, prostatitis, orchitis, seminal vesiculitis, pericarditis, and omphalitis. No statistical association was observed between T. pyogenes infections and age, gender, or season across the study. The most effective drugs against the pathogen were florfenicol (99.1%), cefoperazone (96.0%), cephalexin (95.0%), and ceftiofur (94.8%). High resistance rates were observed against trimethoprim-sulfamethoxazole (49.3%), followed by norfloxacin (10.9%) and tetracycline (9.2%). This study highlights the diversity of clinical manifestations and the opportunistic behavior of T. pyogenes infections in domestic animals, with predominance of mastitis, abscesses, pneumonia, and lymphadenitis. It also reinforces the importance of knowing the susceptibility profile before initiating therapy, to improve antimicrobial therapy approaches.

    Fatty liver hemorrhagic syndrome, characterized by sudden death in overconditioned hens due to hepatic rupture and hemorrhage, is one of the leading noninfectious idiopathic causes of mortality in backyard chickens. Nutritional, genetic, environmental, and hormonal factors, or combinations of these, have been proposed yet not proven as the underlying cause. In an attempt to characterize the hepatic changes leading to the syndrome, this retrospective case study examined 76 backyard chickens that were diagnosed with fatty liver hemorrhagic syndrome between January 2007 and September 2012 and presented for necropsy to the diagnostic laboratory of the California Animal Health and Food Safety Laboratory System. A majority of the birds were female (99%), obese (97.5%), and in active lay (69.7%). Livers were examined histologically, and the degree of hepatocellular vacuolation (lipidosis), the reticular stromal architecture, the presence of collagenous connective tissue, and vascular wall changes were evaluated and graded using hematoxylin and eosin, Gomori's reticulin, oil red O, Masson's trichrome, and Verhoeff-Van Gieson stains. Interestingly, there was no correlation between lipidosis and reticulin grades; hepatocellular lipidosis was absent in 22% of the cases and mild in 26% of the cases. Additionally, there was evidence of repeated bouts of intraparenchymal hemorrhage before the acute "bleed-out" in 35.5% of the cases. These data are not supportive of the previously proposed causes and provide a framework for future studies to elucidate the pathogenesis of this condition. Furthermore, the data shown in this study support hemorrhagic liver syndrome as a more accurate name, as hepatic lipidosis is absent in a significant proportion of ruptured livers. © The Author(s) 2013.

    A juvenile, female North American opossum (Didelphis virginiana) died of verminous pneumonia caused by Didelphostrongylus haysei despite aggressive treatment with oral fenbendazole, corticosteroids, and antibiotics. This prompted a retrospective study of lungworm infection in opossums, during which 19 additional necropsy reports from opossums were reviewed. Including the subject of this report, a total of 11 (55%) of these cases included a diagnosis of lungworm infection. This diagnosis was considered to have contributed to death in eight out of the 11 cases (73%). Histologically, 10 of the 11 (91%) opossums had granulomatous bronchopneumonia with small to moderate numbers of adult nematodes in the airways and parenchyma. Four of the 11 (36%) opossums had free larvae within the parenchyma or terminal airways. Inflammation was usually associated with larvae, degenerating parasites, and nonintact adult nematodes. Superimposed bacterial pneumonia was evident in three animals, and sections of lung examined from all the opossums were characterized by moderate to severe smooth-muscle hyperplasia in airways, including terminal respiratory bronchioles and alveolar ducts. Nine animals had prominent medial smooth-muscle hyperplasia in small- and medium-sized arterioles. Lesions in other organs, particularly in liver, heart, and gastrointestinal tract, were frequently identified. Three animals had concomitant septicemia or bacterial bronchopneumonia (or both), which contributed to the cause of death. Seven animals had gastric nematodosis (Physaloptera sp.), although three of them had been treated with a 14-day course of fenbendazole.

    Full Text Available This retrospective study addresses a series of 156 cases of forearm fractures. These 156 cases were managed in the trauma-orthopedic department (B4 of Fez University Hospital, Morocco, from May 2008 till January 2013. The purpose of this study is to analyze epidemiological and clinical factors of diaphyseal forearm fractures and the results of their treatment with dynamic compression plate (DCP, as well as the complications and therapeutic errors of this surgical technique. The frequency of hospitalization in the trauma-orthopedic department was 3,96%. Ages ranged between 16 and 83, the average age was 32. 132 patients were male (85%. 90% were managed at the day of trauma. Traffic accidents were the most frequent cause in 52% patients. The fracture was in the left forearm in 65% of patients. 53% of fracture lines were in the middle third of the forearm. 38 fractures were open, and 30 were admitted for polytrauma. Osteosynthesis was performed with dynamic compression plate for all patients. In comparison with the literature, our series shows the predominance of young male patients, with traffic accidents being the cause. Osteosynthesis with dynamic compression plate remains the treatment of choice that provides satisfactory results if the accuracy in this technique was respected.

    The autopsy material of the institutes for forensic medicine in Berlin/GDR and Hamburg was analyzed retrospectively (period from 1961 till 1987; 70,000 autopsies) for fatalities caused by "humane killers" (n = 22) and stud guns (n = 12).-Epidemiological, criminological and morphological findings: The decreased were all men aged between 18 and 75 years (mean 48 years) except one 61 year-old paraplegic women who was killed by her husband with a humane killer. The great majority of cases consisted of suicides; two accidents at work were caused by stud guns. These unusual weapons are normally used by skilled people (i.e. butchers or constructional workers respectively). The fatal wounds were situated at the head, especially the forehead, seldom at the nape of the neck or in the mouth, or sometimes in the chest when using stud guns. Combined suicides (especially together with hanging) are not unusual. Survival periods (with or without acting capacity) can range between minutes or even months (after neurosurgical intervention).-The frequency of such unusual and overall rare cases did not raise during the investigation period.

    Odontogenic cysts constitute a major part of oral pathological lesions, but little is known about their distribution patterns in various populations. In this retrospective study, patient records from the archive of the Department of Oral and Maxillofacial Pathology at the Faculty of Dentistry affiliated to the Tehran University of Medical Sciences were reviewed. Cases diagnosed as odontogenic cyst from 1987 to 2007 were selected and histopathologically re-evaluated to confirm the diagnosis. Patients' demographic information (age and sex) and location of the lesion were recorded and analyzed using descriptive statistics. From a total of 8529 files reviewed, the diagnosis of odontogenic cyst was confirmed in 1227 cases (14.4%). The overall male to female ratio was 1.33:1. The patients' age ranged from 3 to 84 years with a mean of 28 years. 49% of cysts were found in maxilla and 50.4% in mandible. Radicular cyst was the most common type followed by dentigerous cyst, odontogenic keratocyst, residual cyst and paradental cyst. Lateral periodontal cyst, eruption cyst, glandular odontogenic cyst and gingival cyst of adults were also reported. The distribution pattern of odontogenic cysts in Iran is relatively similar to that in other parts of the world. The importance of complete clinical reports for final diagnosis of these lesions and routine follow-up examinations is emphasized.

    Psychotimulant-antipyschotic combinations are frequently used in child psychiatry, but have been rarely described in the literature. We propose here a retrospective study of 44 children who received the combination methylphenidate (MPH)-risperidone (RIS). The sample is composed of children who received either MPH (n=28) or RIS (n=16) as primary treatment. A vast majority of the children had a comorbid attention deficit hyperactivity disorder (ADHD) diagnosis. For over 60% of patients, regardless of their initial monotherapy, bitherapy decreased the symptoms of ADHD and conduct disorder, sleep disorders and anxiety. Concerning the safety of the bitherapy, a compensation effect on weight gain and appetite was respectively observed in 70% and 50% of patients. Even though iatrogenic tachycardia can be encountered with both drugs, it has never been reported when they are associated and we have reported a total of 3 cases in our study. We have also observed a case of dyskinesia resolved with the discontinuation of the treatment. MPH-RIS bitherapy appears to be particularly effective in ADHD with conduct disorder symptoms. Although tolerance may limit its use, the benefit/risk ratio seems favourable for a number of children. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    To establish predilection sites of obstruction and to investigate clinical factors associated with a poor outcome. A retrospective study of 208 consecutive cases over a 48-month period from first-opinion practice. Overall, 91 per cent of cases recovered with higher survival rates from discrete foreign bodies (94 per cent in dogs and 100 per cent in cats) as opposed to linear foreign bodies (80 per cent in dogs and 63 per cent in cats). English bull terriers, springer spaniels, Staffordshire bull terriers, Border collies and Jack Russell terriers were over-represented. In dogs, 63 per cent of obstructions occurred in the jejunum but foreign objects were encountered at all points along the gastrointestinal tract. A longer duration of clinical signs, the presence of a linear foreign body and multiple intestinal procedures were associated with significantly increased mortality. Neither the degree of obstruction (partial or complete) nor the location of the foreign body was shown to have a significant influence on survival. Prompt presentation, diagnosis and surgical intervention improve the outcome of gastrointestinal obstruction by foreign bodies. At surgery, the minimal number of intestinal procedures should be performed to restore the integrity of the alimentary tract.

    While it is known that diesel fuel combustion engines produce much lower concentrations of carbon monoxide (CO) than gasoline engines, these emissions could certainly generate lethal ambient concentrations given a sufficient amount of time in an enclosed space and under suitable environmental conditions. The authors report a case of CO poisoning which was initially referred for autopsy as a presumed natural death of a truck driver found in the secure cab of a running diesel tractor trailer truck. Completion of the preliminary investigation ascribed death to complications of ischemic heart disease (IHD), pending toxicological analysis that included quantification of CO. When the toxicology results showed lethal blood COHbg, the cause of death was re-certified as CO intoxication secondary to inhalation of (diesel) vehicular exhaust fumes. Because of the unique source of fatal CO intoxication in this case, the contributory IHD and the possible contaminants in the putrefied blood, a 10-year retrospective review was conducted on all nonfire related CO deaths autopsied (n = 94) at the Office of the Chief Medical Examiner in Louisville, KY from 1994 to 2003. For validation of the COHbg detection method used by the Kentucky Office of Forensic Toxicology (KYOFT), blood samples from these cases along with controls were submitted to three laboratories using various analytical methods yielding no statistically significant differences. Lastly, an extensive literature review produced no scientifically reported cases of fatal CO poisoning attributed to diesel fuel exhaust.

    To investigate the causes of non-hemolytic jaundice among infants in Chongqing, China from the period of 1982 to 2011 and to determine whether the etiologies have changed over the past 30 years. The medical records of 3 113 infants,aged 1 month to 1 year,admitted to our hospital with non-hemolytic jaundice were collected and stratified according to decade-long time periods: group A (1982-1991), n=537; group B (1992-2001), n=786; group C (2002-2011), n=1 790. Data on sex, age, etiology and bilirubin level were retrospectively assessed using the chi-square test. In the three groups, boys consistently accounted for the majority of cases (group A:74.3%, group B:66.7%, group C:62.6%). In group A, 52% of the patients were 1-2 months of age; the peak age of patients in both group B and C was 2-3 months (group B:67.8%, group C:61.0%). Group A showed the highest level of patients with mildly elevated total bilirubin level (80.3%); however, moderately elevated total bilirubin level was most frequent in group B (53.4%) and group C (49.7%). The main etiologic diagnoses of the patients in group A were cytomegalovirus (CMV) infection (31.7%), sepsis (18.2%), hepatitis B virus (HBV) (1.3%), and biliary tract anomalies (1.3%); 46.6% of the cases had unclear cause. The main etiologic diagnoses of the cases in group B were CMV infection (36.0%), sepsis (21.5%), breast milk jaundice (2.0%), and HBV (1.9%); 37.9% of the cases had unclear cause. The main etiologic diagnoses of the cases in group C were CMV infection (42.6%), sepsis (7.5%), breast milk jaundice (17.7%), and biliary tract anomalies (2.46%); 29.1% of the cases had unclear cause. In Chongqing, infective factors, especially CMV, remain the main cause of nonhemolytic jaundice in infants, but bacterial etiologies have declined over the past 30 years.Non-infective factors, such as biliary tract anomalies and inherited metabolic diseases, have trended upwards. Although there has been great progress in the clinical management of

The disease affects mainly children, but in recent years it is becoming more of an adult disease. Malaysia experienced a large dengue outbreak in 2006 to 2007, involving mostly adults, with a high number of deaths. METHODOLOGY/PRINCIPAL FINDINGS: We undertook a retrospective study to examine dengue death cases in our hospital from June 2006 to October 2007 with a view to determine if there have been changes in the presentation of severe to fatal dengue. Nine of ten fatal cases involved adult females with a median age of 32 years. All had secondary dengue infection. The mean duration of illness prior to hospitalization was 4.7 days and deaths occurred at an average of 2.4 days post-admission. Gastrointestinal pain, vomiting, diarrhea, intravascular leakages and bleeding occurred in the majority of cases. DSS complicated with severe bleeding, multi-organ failure and coagulopathy were the primary causes of deaths. Seven patients presented with thrombocytopenia and hypoalbuminemia, five of which had hemoconcentration and increased ALT and AST indicative of liver damage. Co-morbidities particularly diabetes mellitus was common in our cohort. Prominent unusual presentations included acute renal failure, acute respiratory distress syndrome, myocarditis with pericarditis, and hemorrhages over the brain and heart. CONCLUSIONS: In our cohort, dengue fatalities are seen primarily in adult females with secondary dengue infection. The majority of the patients presented with common clinical and laboratory warning signs of severe dengue. Underlying co-morbidities may contribute to the rapid clinical deterioration in severe dengue. The uncommon presentations of dengue are likely a reflection of the changing demographics where adults are now more likely to contract dengue in dengue endemic regions.

    Diagnostic delay of tumor induced osteomalacia (TIO) is common in clinic practice. To investigate the diagnostic condition of TIO in China and raise clinicians' awareness of TIO, we retrospectively analyzed clinical manifestations, biochemical features, and specially evaluated missed diagnoses and misdiagnoses among 144 TIO patients from Peking Union Medical College Hospital during December 1982 to December 2014. Clinical presentations of TIO mainly included bone pain, difficulty in walking, pathological fractures, muscle weakness, and height loss. TIO patients demonstrated hypophosphatemia (0.48±0.13 mmol/L), elevated serum alkaline phosphatase (277.9±152.6 U/L), reduced tubular maximum for phosphorus/glomerular filtration rate (0.39±0.14) and markedly elevated serum fibroblast growth factor 23 (FGF23) (median level 302.9 pg/mL). The average time from onset to a correct diagnosis was 2.9±2.3 years while the mean duration from onset to tumor resection was 5.4±4.2 years. The initial misdiagnosis rate was 95.1% (137/144) and 240 case-times of misdiagnoses occurred among the 144 cases. The most frequent misdiagnoses were intervertebral disc herniation, spondyloarthritis (including ankylosing spondylitis) and osteoporosis. A total of 43.1% (62/144) cases with hypophosphatemia presented on their laboratory sheets were neglected and missed diagnosed. Our study showed that TIO was frequently misdiagnosed and missed diagnosed due to its rarity, insidious onset, nonspecific clinical manifestations and clinicians' poor recognition. It is necessary to test serum phosphorus in patients with musculoskeletal symptoms and difficulty in walking. The measurement of serum FGF23 is rather valuable. Once hypophosphatemia is discovered, TIO should be suspected and it is highly recommended to search for tumors and perform curative surgery.

    Objective: To explore the clinical and histopathological features of primary, intimal sarcoma of the pulmonary artery. Methods: One case of primary intimal sarcoma of the pulmonary artery diagnosed in our hospital and 20 cases published openly in China were analysed retrospectively. Results: The clinical presentation of primary intimal sarcoma of the pulmonary artery was progressive dyspnea, cough, chest pain, syncope, bloody phlegm, fever and fatigue. From the radiological finding, its signs were of pulmonary, artery dilation, reduced pulmonary vasculature and cardiomegaly, soft tissue mass near the right ventricle outflow tract. Histological examination of intimal sarcoma of the pulmonary artery revealed a poorly differentiated mesenchymal tumor of fibroblastic or myofibroblastic differentiation, consisting of mildly atypical spindle cells with atypia, mitosis, and nuclear polymorphism. Immunohistochemical analysis showed positive staining with antibodies against vimentin, alpha-smooth muscle actin, while negative for desmin. Conclusion: Primary, intimal sarcoma of the pulmonary artery has atypical clinical and radiological manifestation with poor prognosis, its definite diagnosis depends on histopathology. (authors)

    Full Text Available Introduction. Pompe disease (PD, a lysosomal storage disease as well as a neuromuscular disorder, is a rare disease marked by progressive muscle weakness. Enzyme replacement therapy (ERT in recent years allowed longer survival but brought new problems to the treatment of PD with increasing affection of the musculoskeletal system, particularly with a significantly higher prevalence of scoliosis. The present paper deals with the orthopedic problems in patients with PD and is the first to describe surgical treatment of scoliosis in PD patients. Patients and Methods. The orthopedic problems and treatment of eight patients with PD from orthopedic consultation for neuromuscular disorders are retrospectively presented. We analyzed the problems of scoliosis, hip dysplasia, feet deformities, and contractures and presented the orthopedic treatment options. Results. Six of our eight PD patients had scoliosis and two young patients were treated by operative spine stabilization with benefits for posture and sitting ability. Hip joint surgery, operative contracture release, and feet deformity correction were performed with benefits for independent activity. Conclusion. Orthopedic management gains importance due to extended survival and musculoskeletal involvement under ERT. Surgical treatment is indicated in distinct cases. Further investigation is required to evidence the effect of surgical spine stabilization in PD.

    Atypical antipsychotics have been associated with weight gain. This study examines the efficacy of adjunctive topiramate in patients with schizophrenia and schizoaffective disorder with antipsychotic-induced weight gain. A 2-year retrospective case analysis was performed in all 300 patients of the outpatient Special Follow-up Clinic for chronic schizophrenia and related psychoses at the Allan Memorial Institute, McGill University Health Centre (Montreal, Canada), a tertiary care University teaching hospital. 10 patients met study inclusion criteria. Mean daily topiramate dose was 197.5 mg (A+/-77) (range, 125-400 mg). Topiramate produced continued weight loss throughout the study duration without tolerance. Patients treated for 6 months and more had significantly higher Body Mass Index (BMI) differences than those treated for shorter durations (BMI-d6 months=-4.7A+/-2.4; BMI-d2 months=-3.2A+/-2.3; P=0.015). BMI changes were similar across genders. This study supports topiramate use to target weight loss in stable overweight schizophrenic patients as a potential therapy that requires further investigation.

    Peroral endoscopic myotomy (POEM) is a newly developed, less invasive treatment for esophageal achalasia that requires general anesthesia under positive pressure ventilation. In this retrospective case series, we describe the anesthetic management of 28 consecutive patients who underwent POEM for esophageal achalasia. Anesthesia was maintained with sevoflurane and remifentanil under positive pressure ventilation through a tracheal tube. Retained contents in the esophagus were evacuated just before anesthesia induction to prevent regurgitation into the trachea. The POEM procedure was performed using an orally inserted flexible fiberscope. Elevation of end-tidal carbon dioxide after initiating esophageal carbon dioxide insufflation was observed in all patients and was treated by minute adjustments to the ventilation volume. Scopolamine butylbromide-induced tachycardia in one patient was treated with landiolol hydrochloride, which is a short-acting beta 1-selective blocker. Minor subcutaneous emphysema around the neck was observed in one patient. POEM was successfully completed, and tracheas were extubated immediately after the procedure in all patients. Our findings suggest that prevention of aspiration pneumonia during anesthesia induction, preparation for carbon dioxide insufflation-related complications, and treatment of scopolamine butylbromide-induced tachycardia play important roles in safe anesthesia management of POEM for esophageal achalasia.

    Estimation of skeletal muscle metastases (SMMs) at the time of diagnosis and/or initial staging of lung cancer. Retrospective evaluation of clinical charts and imaging data suggestive of SMMs of patients with histology-proved lung cancer over a 5-year period. SMMs were identified in 46 out of 1,754 patients. Single and multiple (62.9% of cases) SMMs were detected by total body multi-detector computed tomography (MDCT). They were associated with poorly differentiated (43%) and advanced adenocarcinomas (52%) without clinically relevant symptoms and/or signs. Psoas and buttock muscles were most frequently involved (33.3%). MDCT findings consisted of well-defined homogeneously hyperdense oval masses (31%), lesions with ring-like enhancement and central hypoattenuation (68%), or large abscess-like necrotic lesions (24%). Sonography revealed well-defined hypoechoic masses (41.6%), ill-defined hypoechoic lesions (33.3%), or anechoic areas with a necrotic centre (25%). Positron emission tomography revealed that all SMMs were metabolically active. SMMs are uncommon but not negligible in lung cancer, with an estimated prevalence of 2.62% in our series. Although histology remains the recommended method, use of high-performance imaging techniques and increased clinical suspicion may improve their early detection. Efforts addressing their effect on the natural history of lung cancer are needed.

    To better understand lightning deaths, a retrospective review of electronic records from New Mexico's Office of the Medical Investigator database was performed between 1977 and 2009 to update and assess current risk factors. Information on demographics, circumstances, autopsy, and death certificates were collected and analyzed. Fifty-four decedents were identified, ages 2-71 years old (mean 34 years old), 42 males and 12 females. Common racial/ethnic groups were non-Hispanic Whites and American Indians (together comprising 72% of all cases). Physical findings were often related to the heat carried by the electrical current including clothing alterations (29.6%) and burning of skin (53.7%). Most deaths occurred on weekend afternoons in summer months, associated with recreational activities or agricultural work, and rural locations (77.8%). Utilizing the demographic information, clustered events, and associated outdoor activities will assist in creating public awareness and provide a framework to support targeted warnings in an attempt to prevent future deaths. © 2014 American Academy of Forensic Sciences.

    To review the clinical and diagnostic findings and survival of dilated cardiomyopathy from a large population of dogs in England. A retrospective study of the case records of dogs with dilated cardiomyopathy collected between January 1993 and May 2006. There were 369 dogs with dilated cardiomyopathy of which all were pure-bred dogs except for four. The most commonly affected breeds were dobermanns and boxers. Over 95 per cent of dogs weighed more than 15 kg and 73 per cent were male. The median duration of signs before referral was three weeks with 65 per cent presenting in stage 3 heart failure. The most common signs were breathlessness (67 per cent) and coughing (64 per cent). The majority of dogs (89 per cent) had an arrhythmia at presentation and 74 per cent of dogs had radiographic signs of pulmonary oedema or pleural effusion. The median survival time was 19 weeks. Dilated cardiomyopathy occurs primarily in medium to large breed pure-bred dogs, and males are more frequently affected than females. The duration of clinical signs before referral is often short and the survival times are poor. Greater awareness of affected breeds, clinical signs and diagnostic findings may help in early recognition of this disease which often has a short clinical phase.

    The feline infectious peritonitis virus (FIPV) is a mutated form of the feline enteric coronavirus (FeCV) that can present with a variety of clinical signs. The purpose of this retrospective study was to analyze abdominal ultrasonographic findings associated with cats with confirmed FIPV infection. Sixteen cases were included in the study from a review of medical records at two academic institutions; inclusion was based either on necropsy lesions (n=13) or a combination of histopathological, cytological, and clinicopathological findings highly suggestive of FIPV infection (n=3). The liver was judged to be normal in echogenicity in 11 (69%) cats, diffusely hypoechoic in three cats, focally hyperechoic in one cat, and focally hypoechoic in one cat. Five cats had a hypoechoic subcapsular rim in one (n=3) or both (n=2) kidneys. Free fluid was present in the peritoneal cavity in seven cats and in the retroperitoneal space in one cat. Abdominal lymphadenopathy was noted in nine cats. The spleen was normal in echogenicity in 14 cats and was hypoechoic in two. One cat had bilateral orchitis with loss of normal testicular architecture. Although none of these ultrasonographic findings are specific for FIPV infection, a combination of these findings should increase the index of suspicion for FIPV infection when considered along with appropriate clinical signs.

    To discover if healthcare professionals working within an ED are able to make a diagnosis of female genital mutilation (FGM) in those patients who have previously undergone the procedure and report it as per UK law. A retrospective analysis of patients' notes who were assigned an FGM code during the period of May 2015 to August 2016. Single-centre, large UK major trauma centre offering a tertiary FGM clinic. Any woman coded during the study period as having undergone FGM. Number of FGM cases identified by the ED. Mean age, presenting complaint, discharge diagnosis, genitourinary exam and defibulation status. 34 patients were identified as having undergone FGM, 19 had previously attended ED and none had their FGM identified during their ED attendance. The age range of those identified was 23 to 40 years. None had undergone defibulation. This study demonstrates that the identification of FGM victims by an ED is very poor, and more work needs to be done to increase awareness of the subject by front-line staff. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    2013-01-01

    Full Text Available To highlight a potentially fatal complication of broncho-vascular fistula arising from the self expanding metallic stent (SEMS placement. We retrospectively analyzed five patients with benign and malignant airway diseases, who developed tracheo/broncho-vascular fistulas following SEMS placement in our tertiary care setting. All patients received either Wallstent or Ultraflex® stent (Boston Scientific, Natick, MA between 1999 and 2007. All patients had received adjunct therapy such as balloon bronchoplasty, laser therapy or electrocautery. Most patients presented with massive hemoptysis. A total of 483 SEMS were placed during this period. SEMS placement can be complicated by Broncho-vascular fistula formation. True incidence and precise time interval between the insertion of stent and onset of this complication is unknown. Additional therapeutic modalities to maintain stent patency may enhance the risk of fistula formation. SEMS should only be used in a select sub-group of patients, after exhaustive evaluation of other treatment options. These cases provide evidence that broncho-vascular fistulas can develop at any time following SEMS placement, suggesting the need for a more cautious approach, especially while using them for a long term management. In benign airway disease, the stent should be removed as soon as healing has taken place.

    Full Text Available Purpose. The purpose of this retrospective case series is to describe and compare different surgical techniques that can be utilized to augment the keratinized soft tissue around implant-supported overdentures. Materials and Methods. The data set was extracted as deidentified information from the routine treatment of patients at the Ashman Department of Periodontology and Implant Dentistry at New York University College of Dentistry. Eight edentulous patients were selected to be included in this study. Patients were treated for lack of keratinized tissue prior to implant placement, during the second stage surgery, and after delivery of the final prosthesis. Results. All 8 patients in this study were wearing a complete maxillary and/or mandibular denture for at least a year before the time of the surgery. One of the following surgical techniques was utilized to increase the amount of keratinized tissue: apically positioned flap (APF, pedicle graft (PG, connective tissue graft (CTG, or free gingival graft (FGG. Conclusions. The amount of keratinized tissue should be taken into consideration when planning for implant-supported overdentures. The apical repositioning flap is an effective approach to increase the width of keratinized tissue prior to the implant placement.

    The clinical records of 23 dogs (1990-1999) with histopathologically confirmed bacterial meningoencephalomyelitis were evaluated retrospectively. No breed, age, sex, or weight predisposition was found. All the dogs presented with clinical signs of a brain lesion, whereas 5 of 23 had neck pain. Pyrexia was detected in 11 of 23 dogs on admission. CBCs revealed neutrophilic leucocytosis in 7 of 21 dogs and thrombocytopenia in 3 of 21 dogs. The serum chemistry profiles were abnormal in 15 of 21 dogs. The results of cerebrospinal fluid (CSF) analysis were abnormal in 13 of 14 dogs and aerobic CSF culture was positive for bacteria in 1of 8 samples. At postmortem examination, the lesions were localized to the central nervous system. Escherichia coli, Streptococcus, and Klebsiella spp were the most frequently isolated bacteria from cultures collected at postmortem examination. Twelve papers reporting 51 total clinical cases of canine bacterial meningoencephalomyelitis were reviewed. The clinical signs and results of the CBC, serum chemistry, blood culture, and CSF analysis were collated and compared with those of this study. The results of the CSF analysis in this study were similar to those in the literature. CSF cultures documented in the literature were positive for Staphylococcus, Pasteurella. Actinomyces, Nocardia spp, and various anaerobic species including Peptostreptococcus, Eubacterium, and Bacteroides spp.

    Management of mallet finger is both difficult and controversial. Sequelae are not uncommon, particularly after surgical treatment. Many authors advocate orthopedic treatment which is less invasive but requires greater patient participation to implement. Despite the large number of orthopedic methods proposed, none has proven superiority. We report here our experience with a dorsal adhesive splint which preserves digital pulp function and improves observance. This retrospective analysis included 270 mallet fingers presenting 153 tendon injuries and 117 bony injuries in 265 patients aged 42 years on average and treated from 2003 to 2005. Most of the tendon injuries involved the medius (38.7%) and most of the bony injuries involved the ring finger (35.4%). A splint was fashioned for the two distal phalanges and glued to the nail plate filed for this purpose. The splint was fashioned out of an L-shaped plastic sheet of thermo-malleable plastic dipped in hot water (60 degrees C). The L was molded to the dorsal aspect of the phalanges and rolled like a ring around the second phalanx, then glued to the nail. The splint was worn for eight weeks by patients with a tendon injury and six weeks for those with a bony injury. The splint was then worn at night for two weeks. Three criteria were used to analyze outcome: residual extension deficit, joint involvement, complications. Mean follow-up was 18 months. Mean time from trauma to definitive installation of the splint was six days. The complication rate for this orthopedic method was 14.3%, complications being observed in 6% of patients. All complications were transient except for one case of swan neck deformity and one case of painful osteoarthritis. Thirty splints (11%) became unglued but were all reinstalled using the same protocol. Thirty fingers (14%) presented residual deficit of active extension measuring less than 20 degrees. The quality of the result depended on the type of injury: tendon injuries led to extension

A total of 1,197 case calls yielding 1,525 dogs identified with presumed methionine ingestion. None. Records of dogs with presumptive methionine ingestion were reviewed from the American Society for the Prevention of Cruelty to Animals Animal Poison Control Center database. Ingested methionine doses ranged from 3.9 mg/kg to 23,462 mg/kg. Clinical signs developed in 47% of dogs. The most common clinical signs were gastrointestinal (GI) and neurologic. The mean onset of GI signs was 2.8 hours following ingestion. The mean onset of neurologic signs was 6.8 hours following ingestion. GI signs were identified with ingested doses ≥22.5 mg/kg. Vomiting was the most common GI sign. Neurologic signs were identified with ingested doses ≥94.6 mg/kg. Ataxia was the most common neurologic sign. Resolution of clinical signs occurred within 48 hours of ingestion, and no fatalities were reported. Prognosis for dogs with methionine intoxication is excellent. Vomiting and ataxia were the most common clinical signs associated with methionine toxicosis. © Veterinary Emergency and Critical Care Society 2015.

    Full Text Available INTRODUCTION: Encephalocele is the protrusion of the cranial contents beyond the normal confines of the skull through a defect in the calvarium and is far less common than spinal dysraphism. 1 Anaesthetic challenges in management of occipital meningoencephalocele include securing the airway with intubation in lateral position, intraoperative prone position and its associated complications, careful securing of the endotracheal tube and accurate assessment of blood loss. These babies also have associated congenital anomalie s, gastrointestinal malrotation, renal anomalies, cardiac malformations and tracheoesophageal fistula, making anaesthetic management even more difficult. Meticulous anaesthetic management is crucial for early repair of encephalocoele to prevent any sequel. 2 METHODS: To identify the anaesthetic challenges, perioperative and postoperative complications during encephalocele repair, 20 cases were studied retrospectively from 2012 to 2014 at Department of Anaesthesia , Department of Neurosurgery, MR Medical College, Gulbarga. RESULTS: 20 cases of encephalocoele repair were undertaken during the study period. Out of these 12 (60% were male and 8(40% female. Age range was 1 day to 6 years. Most common type of encephalocele was occipital 12(60%, which posed a difficulty during positioning & intubation, followed by occipito - cervical 4(20%, Parietal 2(10%, Fronto - nasal 1(5% & Fronto - naso - ethmoidal 1(5%. Most of the patients were extubated successfully on table, only one patient required post - operative ventilator support for a day. Peri - operative complications included bronchospasm (15%, followed by hypotension, tachycardia, laryngospasm, hypoxia, accidental extubation (10% each & bradycardia, endobronchial intubation (5%. CONCLUSION: Children with Encephalocoele are prone to have peri - operative complications which can be managed by meticulous anaesthetic managenement. 3 Early surgical management of encephalocoele is not

    To assess the morbidity and mortality associated with complicated diverticulitis in Pakistan. Methods: The retrospective case series was conducted at an urban tertiary care university hospital of Karachi, Pakistan, comprising data from December 1989 to November 2010. International Classification of Diseases codes for diverticular disease and diverticulitis with abscess, fistula, stricture, bowel obstruction and perforation were obtained from the medical record department. SPSS 19 was used for statistical analysis. Results: A total of 60 (1.9%) cases with complicated diverticulitis were located from among 3170 records reviewed. Mean age was 62.7+-13 years with male-to-female ratio being 36:24. In 37 (62%) patients, the diagnosis was established on computed tomography scan of the abdomen, followed by barium enema in 12 (20%) and colonoscopy in 11 (18%). Post-operative morbidity was observed in 24 (40%) and 7 (16%) expired within 28 days of surgery. Post-operative intra-abdominal sepsis, wound dehiscence and incisional hernia were significantly associated with generalised peritonitis (p <0.05), while admission to intensive care unit was associated with age over 60 years and faecal peritonitis. Post-operative mortality was significantly associated with high American Society of Anaesthesiologists-score III and IV and age above 60 years. Conclusion: Complicated diverticulitis carries significant morbidity and mortality in Pakistani population. Since the trend is on the rise, therefore we propose a prospective multi-centre cohort study to understand the spectrum of disease, management and identification of risk factors to achieve the best possible outcomes in patients with complicated diverticulitis.

    Superficial pyoderma is traditionally considered rare in cats but may be more prevalent than previously reported. To better characterize superficial pyoderma in cats. Fifty-two cats from a dermatology referral population over a 10 year period. This study was retrospective. Cases were included if neutrophils and intracellular bacteria were reported from surface cytology of skin lesions. Medical records were reviewed for signalment, historical and clinical data, cytology results, primary skin diagnoses and treatment details. Disease prevalence was 20%, with no breed or sex predispositions. The estimated median age of onset was 2 years, affecting 54% of cats by 3 years and 23% after 9 years. Fewer cases presented during winter (15%) compared with other seasons. Skin lesions were typically multifocal, affecting the face (62%), neck (37%), limbs (33%) and ventral abdomen (29%) most commonly. Crusting (83%), alopecia (67%), ulceration/erosion (54%) and erythema (46%) were common lesion types. Pruritus was reported in 92% of cats. Underlying hypersensitivities (confirmed in 60%; suspected in 19%), and atopic dermatitis specifically (confirmed in 48%), were the most frequent primary dermatoses. Cats were treated with a variety of systemic and/or topical antimicrobials. The overall apparent response was considered good in 61% and poor in 27% of cats. Recurrence was confirmed or suspected in 42% of cats. Feline superficial pyoderma was more prevalent in this study population than previously reported. Young cats with hypersensitivities and older cats were more commonly affected, and a variety of lesion types and distributions occurred. © 2012 The Authors.

    Atopic dermatitis (AD) is recognized as a common cause of pruritus in cats, but it remains incompletely characterized. The aim of the study was to evaluate cases of confirmed feline AD. Fourty-five cats from a dermatology referral practice (2001-2012). A retrospective case record review was carried out using strict diagnostic criteria, including exclusion of flea-bite hypersensitivity and adverse food reaction. Disease prevalence was 12.5%, with domestic mixed (n = 24), Abyssinian (n = 6) and Devon rex (n = 3) cat breeds predisposed. Median age of onset was 2 years (62% 7 years; range 3 months to 12 years). Common presentations were severe (82%), nonseasonal (82%), waxing/waning (36%) pruritus, with alopecia/crusting/excoriations and/or erosions/ulceration (73%). Miliary dermatitis (20%) and eosinophilic granuloma complex lesions (27%) occurred. The face/head (71%), ventral abdomen (51%), neck (51%), limbs (38%), pinnae (31%), dorsum/rump (31%) and feet (16%) were frequently affected sites; lesions were restricted to the head/neck in only five cats (11%). Concurrent otitis externa (16%), superficial bacterial pyoderma (49%), Malassezia dermatitis (7%), flea-bite hypersensitivity (24%) and adverse food reaction (13%) occurred. Strong reactions on intradermal allergen testing were common (68%; 19 of 30), most frequently to pollens (61%) and/or insects (46%). Good response to ciclosporin (100%; 10 of 10), systemic glucocorticoids (55%; 22 of 40) and allergen-specific immunotherapy (57%; 13 of 23) and good/partial response to antihistamines (67%; 22 of 33) were reported. The prevalence of feline AD was higher than previously suggested, and breed predispositions were confirmed. Severe nonseasonal pruritus was most common, with a varied spectrum of lesions affecting a range of body areas. © 2014 ESVD and ACVD.

    Onchocerciasis is caused by Onchocerca volvulus and mainly leads to pruritus and skin and visual disorders, including blindness. Seventeen million people are infected in 38 countries; 31 of these are in sub-Saharan Africa, six in Latin America and one on the Arabian Peninsula. More than 99% of cases occur in sub-Saharan Africa where 120 million people are at risk of infection. Eye disorders have been well-documented; however, skin disorders have not been described accurately. The objective of our study was to describe the epidemiology, main skin manifestations and treatment of imported onchocerciasis. A retrospective study was thus conducted by analysing the main demographic, clinical and treatment data regarding a cohort of 400 patients attending a reference clinical unit over a 17-year period. Most patients were female (55%) with mean age 37.5±16.7 years. All the migrants came from sub-Saharan countries. The most frequently occurring dermatological symptom was pruritus. Ivermectin had been used as first-line therapy and adverse reactions had been described in 11 patients (3.2%). The results indicate the fact that there should be a clinical suspicion of onchocerciasis regarding immigrants from endemic areas having skin lesions compatible with the disease's profile or asymptomatic patients having eosinophilia or unexplained high IgE. Moreover, skin snips from the buttocks region were very fruitful and treatment with ivermectin was seen to be safe. This is the largest case series regarding imported onchocerciasis described up to the present time.

    Objective: To evaluate the effectiveness and safety of rectal ultrasound-guided agon-hilium percutaneous cryoablation in treatment of patients with median and or late-stage prostate cancer patients. Methods: Retrospectively analysis of 42 cases of with stage C and D prostate cancer patients treated by rectal ultrasound-guided argon-hilium percutaneous cryoablation during the follow-up of 1-12 months. The prostate specific antigen (PSA), biochemical progression-free survival (bPFS), PSA objective response, transrectal ultrasound of the prostate (TRUS), TRUS-guided biopsy of the prostate, the maximum urinary flow rate(MFR), MRI examination at before, and 3,6,12 months after cryoablation were recorded and evaluated. The results were statistically evaluated by using variance analysis. Results: The PSA value at before and 3,6, 12 months after cryoablation were (4.48±1.35), (3.54±1.67), (3.18±1.76), (2.87±1.89) μg/L, respectively; TRUS-measured prostate volumes at before and 3, 6,12 months after cryoablation were (59.7± 8.2), (46.9±8.3), (26.2±3.9), (25.9±3.7) mm 3 , respectively; MFR before and 3, 6,12 months after cryoablation were (10.4±0.8), (14.3±1.2), (18.3±1.3), (18.9±1.3) ml/s, respectively; Compared with before cryoablation, the differences between before and after cryoablation was statistically significant (F= 53.93,747.92,3843.03, respectively, P<0.01). The bPFS rates in 3 months,6 months and 12 months were 95.2% (40/42), 95.2% (40/42), and 90.5% (38/42), respectively. According to the PSA response, the total effective rate (CR 16 cases, PR 15 cases) at 12 months was 73.8%, and SD was 16.7% (7/42), PD was 9.5% (4/42). Complications included temporary incontinence 2.4% (1/42), Penile tingling/numbness 2.4% (1/42), pelvic pain 4.9% (2/41) and Scrotum Edema 2.4% (1/42). There was no case with severe complications such as severe infection or urethrorectal fistula, etc. Conclusions: Rectal ultrasound-guided agon-hilium percutaneous cryoablation showed

    This retrospective analysis was performed to evaluate osteolytic bone lesions of breast cancer in the thoracic and lumbar spine after radiotherapy (RT) in terms of stability using a validated scoring system. The stability of 157 osteolytic metastases, treated from January 2000 to January 2012, in 115 patients with breast cancer was evaluated retrospectively using the Taneichi score. Predictive factors for stability were analyzed and survival rates were calculated. Eighty-five (54 %) lesions were classified as unstable prior to RT. After 3 and 6 months, 109 (70 %) and 124 (79 %) lesions, respectively, were classified as stable. Thirty fractures were detected prior to RT, and after RT seven cases (4.5 %) with pathologic fractures were found within 6 months. None of the examined predictive factors showed significant correlation with stability 6 months after RT. After a median follow-up of 16.7 months, Kaplan-Meier estimates revealed an overall survival of 83 % after 5 years. The majority of patients showed an improved or unchanged stability of the involved vertebral bodies after 6 months. The patients showed only minor cancer-related morbidity during follow-up and reached comparably high survival rates. (orig.)

    To evaluate the correlation between the treatment, the characteristics of the lesions and the clinical outcome of patients with traumatic injuries to the craniocervical junction. This was a retrospective study of patients treated conservatively or surgically between 2010 and 2013 with complete data sets. We analyzed 37 patients, 73% were men with mean age of 41.7 years. Of these, 32% were submitted to initial surgical treatment and 68% received conservative treatment. Seven (29%) underwent surgery subsequently. In the surgical group, there were seven cases of odontoid type II fractures, two cases of fracture of posterior elements of the axis, one case of C1-C2 dislocation with associated fractured C2, one case of occipitocervical dislocation, and one case of combined C1 and C2 fractures, and facet dislocation. Only one patient had neurological déficit that improved after treatment. Two surgical complications were seen: a liquoric fistula and one surgical wound infection (reaproached). In the group treated conservatively, odontoid fractures (eight cases) and fractures of the posterior elements of C2 (five cases) were more frequent. In two cases, in addition to the injuries of the craniocervical junction, there were fractures in other segments of the spine. None of the patients who underwent conservative treatment presented neurological deterioration. Although injuries of craniocervical junction are relatively rare, they usually involve fractures of the odontoid and the posterior elements of the axis. Our results recommend early surgical treatment for type II odontoid fractures and ligament injuries, the conservative treatment for other injuries.

    The purpose of this study was to retrospectively evaluate the results from a Helical TomoTherapy Hi-Art treatment system relating to quality controls based on daily static and dynamic output checks using statistical process control methods. Individual value X-charts, exponentially weighted moving average charts, and process capability and acceptability indices were used to monitor the treatment system performance. Daily output values measured from January 2014 to January 2015 were considered. The results obtained showed that, although the process was in control, there was an out-of-control situation in the principal maintenance intervention for the treatment system. In particular, process capability indices showed a decreasing percentage of points in control which was, however, acceptable according to AAPM TG148 guidelines. Our findings underline the importance of restricting the acceptable range of daily output checks and suggest a future line of investigation for a detailed process control of daily output checks for the Helical TomoTherapy Hi-Art treatment system.

    Full Text Available Purpose:To obtain data on the characteristics of low-vision patients seen at a tertiary eye care hospital in India. Methods:Records of 410 patients were retrospectively reviewed at the Centre for Sight Enhancement, L.V.Prasad Eye Institute, Hyderabad, India. Patients underwent a comprehensive clinical low-vision examination. Data obtained included age, gender, consangunity, visual acuity, visual fields, ocular conditions causing low vision and types of low-vision devices and methods prescribed. Results:Two hundred and ninety seven (72% of 450 patients were male. One-fifth were in the 11-20 years age group (21%. Visual acuity in the better eye was <6/18 - 6/60 in almost half these patients (49.3%. One hundred and twenty two patients (29.9% referred with a visual acuity of ≥ 6/18, either had difficulty in reading normal print or had restricted visual fields. The main causes for low vision were: retinitis pigmentosa (19%, diabetic retinopathy (13%, Macular diseases (17.7%, and degenerative myopia (9%. Visual rehabilitation was achieved using accurate correction of ametropia (174 patients, approach magnification (74 patients and telescopes (45 patients for recognising faces, watching television and board work.

    Full Text Available Abstract Objective: The aim of this study was to evaluate tuberculosis control programmes of patients who applied to the Bursa Nilufer Tuberculosis Dispensary and by investigating the changes in the variables over 3 decades. Method: In this retrospective descriptive study, the records of all tuberculosis cases (1662 people treated in the last 30 years (1985-2014 at the Bursa Nilufer Tuberculosis Dispensary were examined. In the analysis, the chi-square test, the trend chi-square test and Fisher's exact test were used. Results: Males comprised 65.2% of the patients. The ages of the patients ranged from 1 to 87 years, and the mean age was 37.4 (95% CI:36.6-38.2. Among the cases, 86.7% were new and 74.1% were pulmonary tuberculosis. In the last decade, the proportion of women, the education level, the proportion of patients who had received a BCG vaccination and the proportion of active employees among women increased by a statistically significant amount, while the proportion of employees among men decreased. Clinical symptoms, such as weakness, anorexia, weight loss, and cough, decreased to a statistically significant degree. In the last decade, the mortality rate was 3.6%, a statistically significant increase compared with previous decades. Mortality was statistically significant higher among patients who were elderly, male, did not have a BCG scar or had a chronic disease. Conclusion: This study reveals the need for studies that determine the risk factors associated with tuberculosis mortality and examine the effectiveness of tuberculosis control programmes. Direct measures to address mortality risk factors can reduce the number of deaths from tuberculosis.

    Different noise sources in fMRI acquisition can lead to spurious false positives and reduced sensitivity. We have developed a biophysically-based model (named FIACH: Functional Image Artefact Correction Heuristic) which extends current retrospective noise control methods in fMRI. FIACH can be applied to both General Linear Model (GLM) and resting state functional connectivity MRI (rs-fcMRI) studies. FIACH is a two-step procedure involving the identification and correction of non-physiological large amplitude temporal signal changes and spatial regions of high temporal instability. We have demonstrated its efficacy in a sample of 42 healthy children while performing language tasks that include overt speech with known activations. We demonstrate large improvements in sensitivity when FIACH is compared with current methods of retrospective correction. FIACH reduces the confounding effects of noise and increases the study's power by explaining significant variance that is not contained within the commonly used motion parameters. The method is particularly useful in detecting activations in inferior temporal regions which have proven problematic for fMRI. We have shown greater reproducibility and robustness of fMRI responses using FIACH in the context of task induced motion. In a clinical setting this will translate to increasing the reliability and sensitivity of fMRI used for the identification of language lateralisation and eloquent cortex. FIACH can benefit studies of cognitive development in young children, patient populations and older adults. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

    Full Text Available Background: Lobular capillary hemangioma of the nasal cavity is an uncommon benign vascular tumor of unknown etiology. There have been only very few case reports in Taiwan. Aims: This study aimed to analyze the clinical features, radiological findings, treatment modalities, and outcome of lobular capillary hemangioma treated at a teaching hospital in Taiwan during a period of 10 years. Study Design: Descriptive study. Methods: Retrospective chart reviews were performed on patients who were diagnosed with lobular capillary hemangioma of the nasal cavity at Kaohsiung Armed Forces General Hospital, Kaohsiung, Taiwan, from January 2003 to December 2012. Data retrieved included age, gender, clinical symptoms, computed tomography (CT findings, treatment modalities, and outcome for further analysis. Results: Of the 15 patients identified, there were five males and ten females ranging from 17 to 86 years of age, with a mean age of 43.8±20.2. Epistaxis was the most common presenting symptom. All patients presented a unilateral nasal lobular capillary hemangioma. The most commonly affected site was the anterior nasal septum, followed by the inferior turbinate, vestibule, middle turbinate, and posterior nasal septum. All lesions presented as soft tissue density without bony erosions under CT examination. Endoscopic excisional surgery (n=12 or classical local excision (n=3 was performed for complete removal of the hemangioma. No evidence of recurrence was observed with 6 to 75 months of follow-up. Conclusion: Lobular capillary hemangioma of the nasal cavity was usually found to occur in anterior septum with epistaxis. Complete excision with endoscopic surgery or classical local excision was recommended and recurrence can be prevented.

    To determine whether primary delusional jealousy can be treated effectively with antipsychotics or antidepressants, and whether any clinical variables are associated with response to pharmacotherapy, we carried out a retrospective case series observational study by reviewing clinical records of patients with an International Classification of Disease, 9th ed., diagnostic code of 297 (delusional disorders) who were treated at the Department of Psychiatry of a university affiliated hospital from January 2010 to December 2015. Only those records showing obvious delusional jealousy not secondary to other medical conditions, dementia, or schizophrenia were scrutinized thoroughly with respect to types of pharmacotherapy, treatment response, and other demographic and clinical variables likely to be associated with clinical outcomes. All except one of 32 patients, 16 men and 16 women, between 37 and 79 (60.9±10.6) years of age, were treated with low-dose antipsychotics. The general response was favorable as 19 (59.4%) were rated as good and 13 as inadequate responders (seven partial and six limited). Compared with antipsychotic monotherapy, concomitant therapy with antidepressants had a higher rate of good response, although statistically insignificant (75 vs. 53%, P=0.21). Younger age (P=0.01) and presentation at the index visit with their suspected unfaithful spouse were associated with a good response (P=0.036); comorbidity with delusions other than the jealous type was associated with a poor response (P=0.006). The overall outcome for delusional jealousy looks promising if the patients can accept pharmacotherapy in an outpatient setting.

    Context: Perioperative outcome of pancreaticoduodenectomy is related to work load volume and to whether the procedure is carried out in a tertiary specialized hepato-pancreatico-biliary (HPB) unit. Objective: To evaluate the perioperative outcome associated with pancreaticoduodenectomy in a newly established HPB unit. Patients: Analysis of 32 patients who underwent pancreaticoduodenectomy (PD) for benign and malignant indications. Design: Retrospective collection of data on preoperative, intraoperative and postoperative care of all patients undergoing PD. Results: Thirty-two patients (16 male and 16 female) with a mean age of 59.5 ± 12.7 years were analyzed. The overall morbidity rate was high at 53%. The most common complication was wound infection (n = 11; 34.4%). Pancreatic and biliary leaks were seen in 5 (15.6%) and 2 (6.2%) cases, respectively, while delayed gastric emptying was recorded in 7 (21.9%). The female sex was not associated with increased morbidity. Presence of co-morbid illness, pylorus-preserving PD, intra-operative blood loss > 1 L, and perioperative blood transfusion were not associated with significantly increased morbidity. The overall hospital mortality was 3.1% and the cumulative overall (OS) and disease free survival (DFS) at 1 year were 80% and 82.3%, respectively. The cumulative overall survival for pancreatic cancer vs ampullary tumor at 1 year were 52% vs 80%, respectively. Conclusion: PD is associated with a low risk of operative death when performed by specialized HPB surgeons even in a tertiary referral hospital. However, the postoperative morbidity rate remains high, mostly due to wound infection. Further improvement by reducing postoperative infection may help curtail the high postoperative morbidity

    Between March 1983 and December 1989, ninety-six patients with intracranial glioma were treated in the Department of Therapeutic Radiology, Kangnam St. Mary Hospital, Catholic University Medical College. We retrospectively reviewed each case to evaluate variable factors influencing the treatment results and to develop an optimal therapy Policy. Median follow-up is 57 months(range:31-133 months). Of the 96 patients, 60(63%) were males and 36(37%) were females. Ages ranged from 3 to 69 years (median 42 years). The most common presenting symptoms were headache(67%) followed by cerebral motor and sensory discrepancy(54%), nausea and vomiting(34%), seizure (19%), mental change(10%) and memory and calculation impairment(8%). Eighty five(88.5%) patients all, except 11(11.5%) brain stem lesions, were biopsy proven intracranial glioma. The distribution by histologic type was 64 astrocytomas(75%), 4 mixed oligoastrocytomas(5%), and 17 oligodendrogliomas(20%). Fourty nine patients (58% were grade I, II histology and 36 (42%) patients were grade III, IV histology. Of the 96 patients, 64(67%) received postoperative RT and 32(33%) were treated with primary radiotherapy. Gross total resection was performed in 14(16%) patients, subtotal resection in 29(34%), partial resection in 21(25%), and biopsy only in 21(25%). Median survival time was 53 months(range 21-133 months), and 2- and, 5-year survival rate were 69%, 49% respectively. 5-year survival rate by histologic grade was grade I, 70%, grade II, 58%, grade III, 28%, and grade IV, 15%. Multivariated analysis demonstrate that age at diagnosis (p=0.121), Karnofsky performance Status(KPS)(p=0.0002), histologic grade(p=0.0001), postoperative radiation therapy(p=0.0278), surgical extent(p=0.024), cerebellar location of tumor(p=0.0095) were significant prognostic factors influencing on survival

    Full Text Available Abstract Background Proximal major limb amputations due to malignant tumors have become rare but are still a valuable treatment option in palliation and in some cases can even cure. The aim of this retrospective study was to analyse outcome in those patients, including the postoperative course, survival, pain, quality of life, and prosthesis usage. Methods Data of 45 consecutive patients was acquired from patient's charts and contact to patients, and general practitioners. Patients with interscapulothoracic amputation (n = 14, shoulder disarticulation (n = 13, hemipelvectomy (n = 3 or hip disarticulation (n = 15 were included. Results The rate of proximal major limb amputations in patients treated for sarcoma was 2.3% (37 out of 1597. Survival for all patients was 42.9% after one year and 12.7% after five years. Survival was significantly better in patients with complete tumor resections. Postoperative chemotherapy and radiation did not prolong survival. Eighteen percent of the patients with malignant disease developed local recurrence. In 44%, postoperative complications were observed. Different modalities of postoperative pain management and the site of the amputation had no significant influence on long-term pain assessment and quality of life. Eighty-seven percent suffered from phantom pain, 15.6% considered their quality of life worse than before the operation. Thirty-two percent of the patients who received a prosthesis used it regularly. Conclusion Proximal major limb amputations severely interfere with patients' body function and are the last, albeit valuable, option within the treatment concept of extremity malignancies or severe infections. Besides short survival, high complication rates, and postoperative pain, patients' quality of life can be improved for the time they have remaining.

    Guilherme Karam Corrêa Leite

    Full Text Available CONTEXT AND OBJECTIVE: The incidence of scar endometrioma ranges from 0.03 to 3.5%. Certain factors relating to knowledge of the clinical history of the disease make correct diagnosis and treatment difficult. The aim here was to identify the clinical pattern of the disease and show surgical results. The literature on this topic was reviewed. DESIGN AND SETTING: Retrospective descriptive study at Hospital Municipal Maternidade - Escola Dr. Mário de Moraes Altenfelder Silva. METHODS: Data from the medical records of patients with preoperative diagnoses of scar endometrioma who underwent operations between 2001 and 2007 were surveyed and reviewed. The postoperative diagnosis came from histopathological analysis. The main information surveyed was age, obstetric antecedents, symptoms, tumor location, size and palpation, duration of complaint, diagnosis and treatment. All patients underwent tumor excision with a safety margin. RESULTS: There were 33 patients, of mean age 30.1 ± 5.0 years (range: 18-41 years. The total incidence was 0.11%: 0.29% in cesarean sections and 0.01% in vaginal deliveries. Twenty-nine tumors (87.9% were located in cesarean scars, two (6.0% in episiotomy scars and two (6.0% in the umbilical region. The main symptom was localized cyclical pain (66.7%, of mean duration 30.5 months (± 23. Surgical treatment was successful in all cases. CONCLUSION: This is an uncommon disease. The most important diagnostic characteristic is coincidence of painful symptoms with menstruation. Patients undergoing cesarean section are at greatest risk: relative risk of 27.37 (P < 0.01.

    The aim was to compare high-resolution computed tomography (HRCT) and thin-section magnetic resonance imaging (MRI) findings of facial nerve hemangioma. The HRCT and MRI characteristics of 17 facial nerve hemangiomas diagnosed between 2006 and 2013 were retrospectively analyzed. All patients included in the study suffered from a space-occupying lesion of soft tissues at the geniculate ganglion fossa. Affected nerve was compared for size and shape with the contralateral unaffected nerve. HRCT showed irregular expansion and broadening of the facial nerve canal, damage of the bone wall and destruction of adjacent bone, with "point"-like or "needle"-like calcifications in 14 cases. The average CT value was 320.9 ± 141.8 Hu. Fourteen patients had a widened labyrinthine segment; 6/17 had a tympanic segment widening; 2/17 had a greater superficial petrosal nerve canal involvement, and 2/17 had an affected internal auditory canal (IAC) segment. On MRI, all lesions were significantly enhanced due to high blood supply. Using 2D FSE T2WI, the lesion detection rate was 82.4 % (14/17). 3D fast imaging employing steady-state acquisition (3D FIESTA) revealed the lesions in all patients. HRCT showed that the average number of involved segments in the facial nerve canal was 2.41, while MRI revealed an average of 2.70 segments (P facial nerve hemangioma were typical, revealing irregular masses growing along the facial nerve canal, with calcifications and rich blood supply. Thin-section enhanced MRI was more accurate in lesion detection and assessment compared with HRCT.

    Full Text Available OBJECTIVE: Sporadic Creutzfeldt-Jakob disease (sCJD is a fatal and transmissible neurodegenerative disorder. However, no studies have reported Chinese specific characteristics of sCJD. We aimed to identify differences in sCJD between Chinese patients and patients from other countries. METHODS: The data from 57 Chinese sCJD patients were retrospectively analyzed, including demographic data, clinical manifestations, laboratory examinations, electroencephalograms (EEGs, diffusion-weighted imaging (DWI scans, positron emission tomography (PET scans, and pathological results. RESULT: The disease was pathologically confirmed in 11 patients. 39 cases were diagnosed as probable sCJD, and 7 were possible. Of the total cases, 33 were male, and 24 were female. The onset age ranged from 36 to 75 years (mean: 55.5, median: 57. Disease onset before the age of 60 occurred in 57.9% of patients. The disease duration from onset to death ranged 5-22 months (mean: 11.6, median: 11, and 51.9% of patients died 7 to 12 months after disease onset. The majority of patients presented with sub-acute onset with progressive dementia. 3 of the 9 patients who took 14-3-3 protein analysis had positive results (33.3%. The sensitivity of EEG was 79.6% (43/54. For DWI and PET examinations, the sensitivities were 94% (47/50 and 94.1% (16/17, respectively. In seven patients who did not show typical hyper-intensities on the first DWI examination, abnormalities of hypo-metabolism in the cerebral cortex were clearly detected by PET. In 13 out of the 17 patients, PET detected extra abnormal regions in addition to the hyper-intense areas observed in DWI. CONCLUSION: This is the first study to indicate that Chinese sCJD patients have a much earlier onset age and a longer disease duration than other populations, which is most likely related to racial differences. The longer disease duration may also be a probable characteristic of Asian populations. PET had high sensitivity for the

    Recently developed methodologies such as climate reanalysis make it possible to create a historical record of climate systems. This paper proposes a methodology called Hydrological Retrospective (HR), which essentially simulates large rainfall datasets, using this as input into hydrological models to develop a record of past hydrology, making it possible to analyze past floods and droughts. We developed a methodology for the Amazon basin, where studies have shown an increase in the intensity and frequency of hydrological extreme events in recent decades. We used eight large precipitation datasets (more than 30 years) as input for a large scale hydrological and hydrodynamic model (MGB-IPH). HR products were then validated against several in situ discharge gauges controlling the main Amazon sub-basins, focusing on maximum and minimum events. For the most accurate HR, based on performance metrics, we performed a forecast skill of HR to detect floods and droughts, comparing the results with in-situ observations. A statistical temporal series trend was performed for intensity of seasonal floods and droughts in the entire Amazon basin. Results indicate that HR could represent most past extreme events well, compared with in-situ observed data, and was consistent with many events reported in literature. Because of their flow duration, some minor regional events were not reported in literature but were captured by HR. To represent past regional hydrology and seasonal hydrological extreme events, we believe it is feasible to use some large precipitation datasets such as i) climate reanalysis, which is mainly based on a land surface component, and ii) datasets based on merged products. A significant upward trend in intensity was seen in maximum annual discharge (related to floods) in western and northwestern regions and for minimum annual discharge (related to droughts) in south and central-south regions of the Amazon basin. Because of the global coverage of rainfall datasets

    Full Text Available Abstract Background Somatotropinoma, a pituitary adenoma characterised by excessive production of growth hormone (GH, is extremely rare in childhood. A genetic defect is evident in some cases; known genetic changes include: multiple endocrine neoplasia type 1 (MEN1; Carney complex; McCune-Albright syndrome; and, more recently identified, aryl hydrocarbon receptor-interacting protein (AIP. We describe seven children with somatotropinoma with a special focus on the differences between genetic and sporadic forms. Methods Seven children who presented in our regional network between 1992 and 2008 were included in this retrospective analysis. First-type therapy was somatostatin (SMS analogues or transsphenoidal surgery. Control was defined as when insulin-like growth factor-1 (IGF-1 levels were within the normal range for the patient's age at 6 months after therapy, associated with decreasing tumour volume. Results Patients were aged 5-17 years and the majority (n = 6 were male. Four patients had an identified genetic mutation (McCune-Albright syndrome: n = 1; MEN1: n = 1; AIP: n = 2; the remaining three cases were sporadic. Accelerated growth rate was reported as the first clinical sign in four patients. Five patients presented with macroadenoma; invasion was noted in four of them (sporadic: n = 1; genetic: n = 3. Six patients were treated with SMS analogues; normalisation of IGF-1 occurred in one patient who had a sporadic intrasellar macroadenoma. Multiple types of therapy were necessary in all patients with an identified genetic mutation (4 types: n = 1; 3 types: n = 2; 2 types: n = 1, whereas two of the three patients with sporadic somatotropinoma required only one type of therapy. Conclusions This is the first series that analyzes the therapeutic response of somatotropinoma in paediatric patients with identified genetic defects. We found that, in children, genetic somatotropinomas are more invasive than sporadic somatotropinomas. Furthermore

    A variety of systemic agents are used to treat lichen planopilaris (LPP) with a limited evidence base. The aim of our study was to retrospectively review the response rate to and tolerability of hydroxychloroquine in a cohort of patients with LPP in an effort to add to the evidence base for its use. Twenty-three patients with a clinical and histopathological diagnosis of LPP who had been treated with hydroxychloroquine for their disease in a single center were identified. A retrospective review of these patients' medical records was performed and physician rated response was documented. Complete response was observed in 61% of our patients, and a further 9% of patients demonstrated partial response. Thirteen percent of patients withdrew from treatment because of suspected adverse effects. Our sample size was small, and data was collected retrospectively. We found hydroxychloroquine to be a reasonable therapeutic choice in LPP. © 2016 Wiley Periodicals, Inc.

    Complex femorotibial dislocation of the knee joint generally results from high-energy trauma caused by a traffic or a contact sport accident. Besides disruption of the cruciate ligaments, in 10-25% of patients present concomitant palsy of the common peroneal nerve and more rarely disruption of the popliteal artery. The purpose of this work was to assess outcome in a monocentric consecutive series of knee dislocations with ischemia due to disruption of the popliteal artery and to focus on specific aspects of management. This retrospective series included eleven men and three women, aged 18 to 74 years (mean 47 years). The right knee was injured in five and the left knee in six. Trauma resulted from a farm accident in six patients, fall from a high level in two, a traffic accident in three and a skiing accident (fall) in one. Two other patients with morbid obesity were fall victims. Nine patients had a single injury, two presented an associated serious head injury, one a severe chest injury, and one multiple trauma with coma, chest contusion, and abdominal lesions. One patient had a fracture of the distal femur with associated ischemia. Five knee dislocations were open with a popliteal wound for three and a posteromedial wound for two. Four patients presented total sciatic nerve palsy and nine palsy of the common peroneal nerve. The dislocation was documented in ten cases: lateral (n=1), anterior (n=4), posterior (n=5). For four patients, the dislocation had been reduced during pre-hospital care. Preoperative arteriography was available for eight patients and confirmed the disruption of the popliteal artery; the diagnosis was obvious in six other patients who were directed immediately to the operative theatre without pre-operative imaging. Revascularization was achieved with a upper popliteal-lower popliteal bypass using an inverted saphenous graft. The graft was harvested from the homolateral greater saphenous vein in eight patients and the contralateral vein in six

    Full Text Available OBJECTIVES: To investigate the clinical manifestation and surgical outcome of spinal osteoblastoma. METHODS: From June 2006 to July 2011, 18 patients with spinal osteoblastoma treated surgically were analyzed retrospectively. There were 11 males and 7 females with an average age of 27.5 years(range, 16-38 years. The tumors were located at C5 in 7, C6 in 6, C7 in 3, C6-T1 1 in 1 and T11 in 1. Based on WBB classification, 16 were 1-3 or 10-12 and 2 were 4-9 and 1-3. 18 operations had been performed with en bloc resection. A posterior approach was used for 16 patients, and a combined posterior and anterior approach was used for 2 patients. Reconstruction using instrumentation and fusion was performed using spinal instrumentation in 13 patients. We used visual analogue scales (VAS to evaluate the change of pain before and after the operation, and the McCormick System to assess functional status of the spine. Imaging test was used to review the stability and recurrence rate of spine cord, and the confluence of graft bones. RESULTS: All cases were followed up for 24-80 months (average, 38.4 months. The average surgical time was 120.8 minutes (range, 80-220 minutes, with the average intraoperative blood loss of 520 ml (range, 300-1200 ml. During the follow-up period, the VAS grade reduced from 6.46±1.32 to 2.26±1.05 (P <0.05. 15 patients had neurological function improved and 3 remained no change which was evaluated by McCormick scale for spinal function status at final follow-up. CONCLUSIONS: Spinal osteoblastoma has its own specific radiographic features. There is some recurrence in simple curettage of tumor lesion. The thoroughly en bloc resection of tumor or spondylectomy, bone fusion and strong in Ter fixation are the key points for successful surgical treatment.

    Although both gender- and sports-specific injuries exist among athletes, gender differences in the types of injuries caused by sports activities, except for anterior cruciate ligament (ACL) injury and anterior knee pain, are not well established. An observational study with a retrospective case-series design was conducted to investigate gender-specific differences in the types of injuries sustained while engaging in sports activities common to both males and females. We analyzed injuries sustained during sports activities including basketball, volleyball, tennis, skiing, track and field, and swimming, using data on age, sex, sports activities, activity levels, and sports injuries that had been computerized at our sports medicine (orthopedics) clinic. Inclusion criteria were sports activities that had a record of >100 injuries in total and athletes aged sports activity. We determined the absolute number of patients in each category and their percentage (proportion) of our cohort. The proportions of common injuries caused by sports activities were investigated, and gender-specific differences in the types of common injuries caused by sports activities were clarified. The Fisher exact test was used to determine the significance (P gender-specific differences in the types of sports injuries. According to our database, during the 14-year period between October 1992 and December 2006, a total of 2,989 athletes (1,624 males and 1,365 females) aged sports activities described consulted our sports medicine clinic. The most common sports injuries were ACL injury (14.3%) and knee pain (13.7%), followed by ankle sprain (9.4%), lumbar disc disease (7.0%), meniscus injury (5.1%), stress fracture (2.9%), low back pain (2.5%), patellar tendinitis (2.1%), injury of the medial collateral ligament of the knee (2.0%), lumbar spondylolysis (1.7%), and muscle strain (1.5%). Among these 11 types of sports injuries, a significantly higher proportion of females who engaged in basketball

    Village health workers (VHWs) in five villages in Bugoye subcounty (Kasese District, Uganda) provide integrated community case management (iCCM) services, in which VHWs evaluate and treat malaria, pneumonia, and diarrhoea in children under 5 years of age. VHWs use a "Sick Child Job Aid" that guides them through the evaluation and treatment of these illnesses. A retrospective observational study was conducted to measure the quality of iCCM care provided by 23 VHWs in 5 villages in Bugoye subcounty over a 2-year period. Patient characteristics and clinical services were summarized using existing aggregate programme data. Lot quality assurance sampling of individual patient records was used to estimate adherence to the iCCM algorithm, VHW-level quality (based on adherence to the iCCM protocol), and change over time in quality of care (using generalized estimating equations regression modelling). For each of 23 VHWs, 25 patient visits were randomly selected from a 2-year period after iCCM care initiation. In these visits, 97% (150) of patients with diarrhoea were treated with oral rehydration and zinc, 95% (216) of patients with pneumonia were treated with amoxicillin, and 94% (240) of patients with malaria were treated with artemisinin-based combination therapy or rectal artesunate. However, only 44% (44) of patients with a negative rapid test for malaria were appropriately referred to a health facility. Overall, 75% (434) of patients received all the correct evaluation and management steps. Only 9 (39%) of the 23 VHWs met the pre-determined LQAS threshold for high-quality care over the 2-year observation period. Quality of care increased significantly in the first 6 months after initiation of iCCM services (p = 0.003), and then plateaued during months 7-24. Quality of care was high for uncomplicated malaria, pneumonia and diarrhoea. Overall quality of care was lower, in part because VHWs often did not follow the guidelines to refer patients with fever who tested

    There is much research using statistical process control (SPC) to monitor surgical performance, including comparisons among groups to detect small process shifts, but few of these studies have included a stabilization process. This study aimed to analyse the performance of surgeons in operating room (OR) and set a benchmark by SPC after stabilized process. The OR profile of 499 patients who underwent laparoscopic cholecystectomy performed by 16 surgeons at a tertiary hospital in Taiwan during 2005 and 2006 were recorded. SPC was applied to analyse operative and non-operative times using the following five steps: first, the times were divided into two segments; second, they were normalized; third, they were evaluated as individual processes; fourth, the ARL(0) was calculated;, and fifth, the different groups (surgeons) were compared. Outliers were excluded to ensure stability for each group and to facilitate inter-group comparison. The results showed that in the stabilized process, only one surgeon exhibited a significantly shorter total process time (including operative time and non-operative time). In this study, we use five steps to demonstrate how to control surgical and non-surgical time in phase I. There are some measures that can be taken to prevent skew and instability in the process. Also, using SPC, one surgeon can be shown to be a real benchmark. © 2010 Blackwell Publishing Ltd.

    This study compares diagnosis, staging, and treatment of newly diagnosed breast cancer cases over a several-year period. The study design was a retrospective, multiyear comparison between new breast cancer cases diagnosed in 1995 (n = 827) and 1997 (n = 815). Cases were identified through claims data, and medical record abstraction was used to verify each case and to identify clinical staging and type of treatment. All medical records were reviewed by one physician to maximize internal reliability. Both cohorts were predominantly 40 and older, white, married, and postmenopausal. The latter cohort (1997) had a higher proportion of women aged 70 to 79 and a lower proportion of women aged 40 to 49. In both cohorts, women age 40 and older were likely to be diagnosed with breast cancer at the time of mammographic screening, while women younger than 40 were more likely to be diagnosed by clinical breast examination. In logistic regression analyses, controlling for confounding factors such as age, undergoing mammographic screening increased the likelihood of having a low cancer stage at diagnosis by more than three and a half times. Mammographic screening was statistically significantly positively associated with having eligibility for breast-conserving treatment (BCT); however, although an increase in BCT eligibility was observed, actual use of BCT did not change. Mammography leads to a lower clinical stage as well as a greater likelihood of BCT eligibility at time of breast cancer diagnosis, but may not have a substantial effect on treatment choice (lumpectomy vs. mastectomy). Between 1995 and 1997, a trend was observed toward downstaging of disease at diagnosis; further research is warranted to observe whether this trend continues over time.

    The authors report 10 cases of localised sarcoptic mange in dogs. In each case, lesions were localised to one precise area of the skin. Pruritus was present in nine cases and absent in one. Affected areas were the feet (one case), the face and/or the pinnae (six cases), the abdominal skin (one case), the flank (one case) and the lumbar area (one case). The types of lesions were erythema, papules, lichenification, scales, crusts and alopecia. Parasites were found in all cases except one, in which anti-immunoglobulin G Sarcoptes serology was positive. The acaricidal treatments given were lindane, ivermectin or selamectin and were all successful.

    Full Text Available Abstract Objective: The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods: Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results: Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5% patients (mean age, 50.9 years; age range, 42-58 years; 42% female. Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion: Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

    Over decades, large amounts of the neurotoxin lead were released into the European environment, mostly from gasoline lead additives. Emissions were growing unabatedly until the 1970s, when a series of regulations on the allowed gasoline lead content were adopted. As a result, in the 1990s most gasoline contained only small amounts of lead. We have examined this case of environmental pollution and regulation, and performed a retrospective assessment of the extent of regional-scale lead pollution and the effects of gasoline lead regulations in Europe. With the help of a regional climate model, NCEP re-analyses, spatially disaggregated lead emissions from road traffic and point sources, and various local data, the airborne pathways and depositions of gasoline lead in Europe since 1958 were reconstructed. It turns out that this approach is successful in describing the time-variable, spatially disaggregated deposition of gasoline lead. Additional data from analyses of concentrations in biota, including plant leaves, mussels and human blood, allows an assessment about the impact of the lead phase-out on the quality of the environment. Demonstrating the success of the lead policies, concentrations in leaves and human blood have steadily declined since the early 1980s. At the same time, the economic repercussions that had been feared did not emerge. Instead, the affected mineral oil and car manufacturing industries in Germany (our case-study) were able to deal with the effort without incurring significant extra costs. We suggest that our method of quantitatively reconstructing and anticipating fluxes and depositions of substances can be applied to other relevant substances as well, such as, for example, Persistent Organic Pollutants, radioactive substances or pollens.

    Peroral endoscopic myotomy (POEM) is a novel technique for treating esophageal achalasia. During POEM, carbon dioxide (CO 2 ) is insufflated to aid surgical dissection, but it may inadvertently track into surrounding tissues, causing systemic CO 2 uptake and tension capnoperitoneum. This in turn may affect cardiorespiratory function. This study quantified these cardiorespiratory effects and treatment by hyperventilation and percutaneous abdominal needle decompression (PND). One hundred and seventy-three consecutive patients who underwent POEM were included in this four-year retrospective study. Procedure-related changes in peak inspiratory pressure (p max ), end-tidal CO 2 levels (etCO 2 ), minute ventilation (MV), mean arterial pressure (MAP), and heart rate (HR) were analyzed. We also quantified the impact of PND on these cardiorespiratory parameters. During the endoscopic procedure, cardiorespiratory parameters increased from baseline: p max 15.1 (4.5) vs 19.8 (4.7) cm H 2 O; etCO 2 4.5 (0.4) vs 5.5 (0.9) kPa [34.0 (2.9) vs 41.6 (6.9) mmHg]; MAP 73.9 (9.7) vs 99.3 (15.2) mmHg; HR 67.6 (12.4) vs 85.3 (16.4) min -1 (P < 0.001 for each). Hyperventilation [MV 5.9 (1.2) vs 9.0 (1.8) L·min -1 , P < 0.001] was applied to counteract iatrogenic hypercapnia. Individuals with tension capnoperitoneum treated with PND (n = 55) had higher peak p max values [22.8 (5.7) vs 18.4 (3.3) cm H 2 O, P < 0.001] than patients who did not require PND. After PND, p max [22.8 (5.7) vs 19.9 (4.3) cm H 2 O, P = 0.045] and MAP [98.2 (16.3) vs 88.6 (11.8) mmHg, P = 0.013] decreased. Adverse events included pneumothorax (n = 1), transient myocardial ischemia (n = 1), and subcutaneous emphysema (n = 49). The latter precluded immediate extubation in eight cases. Postanesthesia care unit (PACU) stay was longer in individuals with subcutaneous emphysema than in those without [74.9 min (34.5) vs 61.5 (26.8 min), P = 0.007].

    Cushing disease (CD) results from excessive exposure to glucocorticoids caused by an adrenocorticotropic hormone-secreting pituitary tumor. Inadequately treated CD is associated with significant morbidity and elevated mortality. Multicenter data on CD patients treated in routine clinical practice are needed to assess treatment outcomes in this rare disorder. The study purpose was to describe the burden of illness and treatment outcomes for CD patients. Eight pituitary centers in four U.S. regions participated in this multicenter retrospective chart review study. Subjects were CD patients diagnosed at ≥18 years of age within the past 20 years. Descriptive statistical analyses were conducted to examine presenting signs, symptoms, comorbidities, and treatment outcomes. Of 230 patients, 79% were female (median age at diagnosis, 39 years; range, 18 to 78 years). Length of follow-up was 0 to 27.5 years (median, 1.9 years). Pituitary adenomas were 0 to 51 mm. The most common presenting comorbidities included hypertension (67.3%), polycystic ovary syndrome (43.5%), and hyperlipidemia (41.5%). Biochemical control was achieved with initial pituitary surgery in 41.4% patients (91 of 220), not achieved in 50.0% of patients (110 of 220), and undetermined in 8.6% of patients (19 of 220). At the end of follow-up, control had been achieved with a variety of treatment methods in 49.1% of patients (110 of 224), not achieved in 29.9% of patients (67 of 224), and undetermined in 21.0% of patients (47 of 224). Despite multiple treatments, at the end of follow-up, biochemical control was still not achieved in up to 30% of patients. These multicenter data demonstrate that in routine clinical practice, initial and long-term control is not achieved in a substantial number of patients with CD.

    A patient was identified with severe metabolic acidosis, a high anion gap and 5-oxoproline accumulation, probably caused by the simultaneous use of paracetamol (acetaminophen) and flucloxacillin. We wanted to investigate the necessity to control the interaction between both drugs with an automatic alert system. To investigate the relevance of the interaction of paracetamol and flucloxacillin, a retrospective study was conducted. Data on paracetamol and flucloxacillin prescriptions and laboratory data (pH, Na + , HCO 3 - , Cl - , albumin and 5-oxoproline levels) were combined to assess the prevalence of acidosis, calculate the anion gap and analyse 5-oxoproline levels in clinically admitted patients using both drugs simultaneously. In the 2-year study period, approximately 53,000 admissions took place in our hospital. One thousand and fifty-seven patients used paracetamol and flucloxacillin simultaneously, of which 51 patients (4.8%) had a serum pH ≤ 7.35. One patient, the same patient as presented in the case report, had a high anion gap and a toxic level of 5-oxoproline. The prevalence of metabolic acidosis is very low and the only patient identified with the interaction was recognised during normal clinical care. We conclude that automatic alerts based on simultaneous use of paracetamol and flucloxacillin will generate too many signals. To recognise patients earlier and prevent severe outcomes, a warning system (clinical rule) based on paracetamol, flucloxacillin and pH measurement may be helpful. Early calculation of the anion gap can narrow the differential diagnosis of patients with metabolic acidosis and measurement of 5-oxoproline can explain acidosis due the interaction of paracetamol and flucloxacillin.

    Objective: To retrospectively review the imaging features of surgically and pathologically confirmed intracranial hemangiopericytoma and anaplastic hemangiopericytoma. Methods: Thirty-nine cases of surgically and pathologically confirmed hemangiopericytoma and anaplastic hemangiopericytoma were analyzed retrospectively. The MRI features were compared with pathological findings in all cases. Results: Of the 39 cases, 21 were anaplastic hemangiopericytoma (WHO grade III) and the remaining cases were hemangiopericytoma (WHO grade II); all lesions were solitary. MRI of anaplastic hemangiopericytoma showed that 20 cases were lobulated, and nine grew cross-leaf. The lesions showed mixed iso-high-low signal (n = 20) or iso-signal (n = 1) on plain T1WI, and mixed high-low signal (n = 20) or iso-signal (n = 1) on plain T2WI. After contrast injection, marked heterogeneous enhancement was seen in 19 cases. Significant necrosis and cystic changes were seen in 16 cases, and the “dural tail sign” was found in two cases. Ten cases had bony destruction, and 16 showed significant peritumoral edema. In 18 cases of hemangiopericytoma, nine were oval-shaped and three grew cross-leaf. The lesions showed mixed iso-low signal (n = 10) or iso-signal (n = 8) on plain T1WI, and mixed iso-high signal (n = 10) or iso-signal (n = 8) on plain T2WI. After contrast injection, significant uniform enhancement was seen in 10 cases. Significant necrosis and cystic changes were seen in seven cases, and “dural tail sign” was seen in six cases. Two cases had bony destruction. No case showed significant peritumoral edema. Pathological immunohistochemical Ki67 staining showed a concentration of ∼18.4% positive cells in anaplastic hemangiopericytoma, whereas in hemangiopericytoma it was 7.12%. Conclusion: Imaging findings of intracranial anaplastic hemangiopericytoma had more pronounced lobulation, cross-leaf growth tendency, more and easier bleeding, more necrosis, more cystic changes giving

    Background Little information is available regarding the effect of conventional radiotherapy on glioma-related seizures. Methods In this retrospective study, we analyzed the seizure response and outcome following conventional radiotherapy in a cohort of 43 patients with glioma (33 grade II, 10 grade III) and medically intractable epilepsy. Results At 3 months after radiotherapy, seizure reduction was significant (≥50% reduction of frequency compared with baseline) in 31/43 patients (72%) of the whole series and in 25/33 patients (76%) with grade II gliomas, whereas at 12 months seizure reduction was significant in 26/34 (76%) and in 19/25 (76%) patients, respectively. Seizure reduction was observed more often among patients displaying an objective tumor response on MRI, but patients with no change on MRI also had a significant seizure reduction. Seizure freedom (Engel class I) was achieved at 12 months in 32% of all patients and in 38% of patients with grade II tumors. Timing of radiotherapy and duration of seizures prior to radiotherapy were significantly associated with seizure reduction. Conclusions This study showed that a high proportion of patients with medically intractable epilepsy from diffuse gliomas derive a significant and durable benefit from radiotherapy in terms of epilepsy control and that this positive effect is not strictly associated with tumor shrinkage as shown on MRI. Radiotherapy at tumor progression seems as effective as early radiotherapy after surgery. Prospective studies must confirm and better characterize the response to radiotherapy. PMID:23897633

    Herbal medicine is increasingly used in depressed patients. The purpose of this retrospective controlled study was to evaluate the efficacy and safety of herbal medicine treatment of severe depressive episode. A total of 146 severely depressed subjects were selected from patients who were admitted to the Department of Psychosomatics of Tongde Hospital at Hangzhou, China between 1st September 2009 and 30th November 2013. While all were medicated with psychotropic drugs, 78 received additional individualized herbal medicine. The severity of depressive symptoms was measured using 24-item Hamilton Rating Scale for Depression (HAMD-24) at admission and thereafter once weekly during hospital stay. The proportion of patients achieving clinical response and remission and incidence of adverse events were compared. The two groups had similar average length of hospital stay for approximately 28 days and were not different in the use of psychotropic medications. Survival analysis revealed that patients with herbal medicine had significantly higher chance of achieving clinical response [relative risk (RR)=2.179, Pherbal medicine. Patients with herbal medicine experienced remarkably fewer incidences of physical tiredness, headache, palpitation, dry mouth and constipation, but had a significantly higher incidence of digestive discomfort compared to patients without herbal medicine. These results indicate that additional treatment with individualized herbal medicine enhances antidepressant response and reduces certain side effects associated with psychotropic medications. Herbal medicine is an effective and relatively safe therapy for severe depressive episode (Trial Registration: ChiCTR-OCH-13003864). Copyright © 2014 Elsevier B.V. All rights reserved.

    We aimed to analyze the outcomes of hypofractionated high-energy electron beam radiotherapy for the treatment of keloids. From February 1998 to January 2012, 568 patients with a total of 834 keloids underwent radiotherapy: 826 lesions with postoperative radiotherapy, and 36 with skin-grafting. Lesion size was >5 cm in 335 keloids. An electron-beam of 6 or 7 MeV was used, with a total dose of 18 Gy (two fractions with a 1-week interval) covering the lesion with a 1-cm margin. The time between surgery and radiotherapy was 24–48 h. Skin-grafted patients underwent radiotherapy 10–15 days after the operation. The median follow-up was 40 months (range: 12–160 months). The local control rate was 88.25% (736/834). The relapse rate was 9.59% (80/834), and the time to relapse was 6–28 months (median: 12 months). Univariate analyses showed that gender, age, keloid size, keloid site, skin grafting, and operation-to-irradiation interval influenced the local control rate. Multivariate analysis showed that the relapse rate was correlated with gender (P = 0.048), age (P < 0.01), operation-to-irradiation interval (P < 0.01), keloid site (P < 0.01), surgical method (P = 0.04) and keloid size (P < 0.02). Adverse effects were observed in 9.83% (82/834). No radiation-induced cancers were observed. Hypofractionated high-energy electron beam radiotherapy for keloids yielded excellent outcomes, especially in cases without skin grafting. Early postoperative radiotherapy with limited hypofractionation could be a good choice for keloid treatment. (author)

    The objectives of this work were to retrospectively describe the radiographic assessment of INBONE total ankle arthroplasty in 30 patients using validated linear and angular measurements and to correlate these findings with the final surgical outcome over a 2-year follow-up period. Thirty consecutive patients (21 females, nine males; mean age, 64.8 years) underwent INBONE total ankle arthroplasty during 2007-2011. After IRB approval, a retrospective pre- and post-operative radiographic analysis was performed using validated linear and angular measurements. The pre- and post-operative assessment included the tibial angle, talar angle, tibial slope, and coronal deformity. Post-operative measurements also included the talocalcaneal angle, joint space height, talar height, lateral tibial component angle, lateral talar component angle, and anteroposterior tibial component angle. The post-operative bone loss, subluxation, positioning, and subsidence were also assessed. Statistical analysis was performed using two-sample t test and Fisher's exact test. Out of 30 patients, 23 had a successful clinical outcome with intact prosthesis at a 2-year follow-up. The only variables with significant correlation (p < 0.05) to the post-surgical outcome were the lateral talar component angle (p = 0.002) and the mean difference between pre- and post-operative tibial slope (p = 0.001). The coronal deformity had significant mean difference between pre- and post-operative values (p < 0.001); however, it lacked a significant correlation to the final surgical outcome. None of the categorical variables had a significant correlation with post-surgical outcome. In our retrospective study, only the lateral talar component angle and the mean difference between the pre- and post-operative tibial slope had significant correlation with post-surgical outcome in INBONE ankle arthroplasty. These measurements may be helpful in radiographic assessment of the INBONE ankle arthroplasty. (orig.)

    ESR/tooth enamel dosimetry technique was used for individual retrospective dosimetry of the servicemen who had worked in 1986-1987 at the liquidation of consequences of the Chernobyl accident. For 18 investigated cases, the values varied from 0,10 (sensitivity limit) to 1,75 Gy. The same technique was used for individual dosimetry of wild animals boars, red deers, elks) hunted at contaminated 30-km area around the Chernobyl Power Plant. Measured values varied from 0,20 to 5,0 Gy/year and were compared with calculated for external and internal irradiation

    Full Text Available Aim Urinary tract infection is one of the most common serious bacterial infections in children. Due to regional differences and past infections, the use of antibiotics has problems such as variability in microorganisms and antibiotic susceptibility. In this study, we aimed to determine the microorganisms detected in urinary tract infections in children and their antibiotic resistance status.Methods A retrospective observational study was planned. Demographic data, urine microscopy and urine culture results of patients who were hospitalized with urinary tract infection diagnosis in our pediatric clinic at hospital were recorded retrospectively through hospital automation system. The first culture results of the patients were used in the evaluation of the data. Results In the study group of 112 patients, Escherichia coli (E. coli and Klebsiella were the most identified microorganisms in patients with urinary culture. Under 2 years old, Klebsiella was more frequent, and at 2 years of age there was a noticeable increase in the frequency of E-coli. The most common resistance of both microorganisms was found to be ampicillin. Conclusions: Regional infectious agents and antibiotic resistance should be revised at regular intervals, appropriate empiric therapy should be considered. Thus, is predicted that the chance of success in treatment will increase and the speed of resistance development will decrease.

    The purpose of our work was to assess the value of abdominal sonography (US) and computed tomography (CT) in the preoperative diagnosis of appendiceal mucocele. We retrospectively reviewed 10 cases of mucocele of the appendix, 7 cases without pseudo myxoma peritonei, and 3 cases with pseudo-myxoma peritonei. All cases were investigated radiologically by plain film and US, barium enema was performed in 3 cases and CT in 5 cases. Mucoceles of the appendix are rare and their clinical presentation is not specific. US confirms the appendicular involvement, but often poses the differential diagnosis with acute inflammation, abscess or localized appendicular peritonitis. CT appears as a mandatory examination since it allows accurate preoperative diagnosis period. In this series, the diagnosis was made preoperatively in the 5 cases where CT had been performed. US is useful to confirm the abnormal pattern of the appendix but does not allow accurate diagnosis of mucocele. CT is more specific and accurate for diagnosis of mucocele of the appendix. (authors)

    Observational studies, such as cohort and case-control studies, are valuable instruments in evidence-based medicine. Case-control studies, in particular, are becoming increasingly popular in the neurosurgical literature due to their low cost and relative ease of execution; however, no one has yet systematically assessed these types of studies for quality in methodology and reporting. The authors performed a literature search using PubMed/MEDLINE to identify all studies that explicitly identified themselves as "case-control" and were published in the JNS Publishing Group journals (Journal of Neurosurgery, Journal of Neurosurgery: Pediatrics, Journal of Neurosurgery: Spine, and Neurosurgical Focus) or Neurosurgery. Each paper was evaluated for 22 descriptive variables and then categorized as having either met or missed the basic definition of a case-control study. All studies that evaluated risk factors for a well-defined outcome were considered true case-control studies. The authors sought to identify key features or phrases that were or were not predictive of a true case-control study. Those papers that satisfied the definition were further evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. The search detected 67 papers that met the inclusion criteria, of which 32 (48%) represented true case-control studies. The frequency of true case-control studies has not changed with time. Use of odds ratios (ORs) and logistic regression (LR) analysis were strong positive predictors of true case-control studies (for odds ratios, OR 15.33 and 95% CI 4.52-51.97; for logistic regression analysis, OR 8.77 and 95% CI 2.69-28.56). Conversely, negative predictors included focus on a procedure/intervention (OR 0.35, 95% CI 0.13-0.998) and use of the word "outcome" in the Results section (OR 0.23, 95% CI 0.082-0.65). After exclusion of nested case-control studies, the negative correlation between focus on a procedure

    A longitudinal, retrospective and descriptive study about child abuse was carried out in the Hospitals of the Tlaxcala Secretariat of Health, Mexico. The information was obtained from hospitalized children's charts between January first and November 30, 1991. The charts included were those belonging to zero to 14 year old children with injuries, poisoning, and II-III degrees of malnutrition. Four child-abuse criteria were established: physical, sexual, non organic malnutrition and mixed (physical and non organic malnutrition). Two control groups were defined. Different patterns were observed between accidental and non accidental injuries, malnutrition and poisoning among the case and the control groups. The study provides useful information for the integral diagnosis of child abuse in hospitalized children.

    Full Text Available Background and Objective. The aim of this study was to assess the subjective outcome following laparoscopic sacropexy. Methods. We performed a retrospective cohort study among women treated for descensus with laparoscopic sacropexy between January 2000 and December 2007. 310 patients received questionnaires during followup assessing major pre- and postoperative symptoms and overall satisfaction. Results. 214 (69% patients responded to the questionnaire. Mean followup was 24.5 months. The number of patients with back or lower abdominal pain, foreign body sensation in the vagina and prolapse-related symptoms, urinary symptoms, vaginal and bladder infections, and the need for pessary usage decreased significantly postsurgically. Bowel symptoms increased slightly but not significantly. Two years after surgery, nearly 2 thirds of the women were satisfied or very satisfied with the outcome. Conclusion. Laparoscopic sacropexy is an effective treatment of descensus, with favorable or satisfactory subjective outcomes.

    About 40% of the general population report dyspepsia at some time in their life making it a fairly common disease. Uncomplicated dyspepsia refers to patients whose dyspepsia is not accompanied by alarm features or associated with NSAIDS usage. To assess the need for UGI Endoscopy and find out the patterns of different endoscopic presentations in patients presenting with uncomplicated dyspepsia. Our study conducted in KR Hospital, Mysore, Department of General Surgery is a retrospective endoscopic study of 1450 patients with uncomplicated dysepsia. A significant 64% of the patients presenting with uncomplicated dyspepsia were found to have findings on endoscopy. The most common age range for positive endoscopic findings was 40-50 years in our hospital. Malignancy was diagnosed in 2.5% patients. We recommend upper GI endoscopy in patients presenting with uncomplicated dyspepsia for patients above 40 years of age in our hospital.

    Readmissions within 30-days of hospital discharge are a problem. The aim was to determine if the Better Outcomes for Older Adults through Safe Transitions (BOOST) risk assessment tool was applicable within the UK. Patients over 65 readmitted were identified retrospectively via a casenote review. BOOST assessment was applied with 1 point for each risk factor. 324 patients were readmitted (mean age 77 years) with a median of 7 days between discharge and readmission. The median BOOST score was 3 (IQR 2-4) with polypharmacy evident in 88% and prior hospitalisation in 70%. The tool correctly predicted 90% of readmissions using two or more risk factors and 99.1% if one risk factor was included. The BOOST assessment tool appears appropriate in predicting readmissions however further analysis is required to determine its precision.

    Full Text Available STUDY DESIGN: A retrospective clinical study. OBJECTIVE: To evaluate the clinical efficacy of the surgical treatment of noncontiguous spinal tuberculosis (NSTB, and to discuss its therapeutic strategies. METHODS: We performed a retrospective review of clinical and radiographic data that were prospectively collected on 550 consecutive spinal tubercular patients including 27 patients who were diagnosed and treated as NSTB in our institution from June 2005 to June 2011. Apart from 4 patients being treated conservatively, the remainder received surgery by posterior transforaminal debridement, interbody fusion with instrumentation, posterior instrumentation and anterior debridement with fusion in a single or two-stage operation. The clinical outcomes were evaluated before and after treatment in terms of hematologic and radiographic examinations, bone fusion and neurologic status. The Oswestry Disability Index score was determined before treatment and at the last follow-up visit. RESULTS: 23 patients (15 M/8F, averaged 44.6 ± 14.2 years old (range, 19 to 70 yd, who received surgical treatment, were followed up after surgery for a mean of 52.5 ± 19.5 months (range, 24 to 72 months. The kyphotic angle was changed significantly between pre- and postoperation (P<0.05. The mean amount of correction was 12.6 ± 7.2 degrees, with a small loss of correction at last follow-up. All patients achieved solid bone fusion. No patients with neurological deficit deteriorated postoperatively. Neither mortalities nor any major complications were found. There was a significant difference of Oswestry Disability Index scores between preoperation and the final follow-up. CONCLUSION: The outcomes of follow-up showed that posterior and posterior-anterior surgical treatment methods were both viable surgical options for NSTB. Posterior transforaminal debridement, interbody fusion and posterior instrumentation, as a less invasive technique, was feasible and effective to treat

    The aim of this retrospective study was to evaluate the effectiveness of laser therapy for acceleration and recovery of nerve sensitivity after orthognathic or minor oral surgeries, by analysis of clinical records of patients treated at the Special Laboratory of Lasers in Dentistry (LELO, School of Dentistry, University of São Paulo), throughout the period 2007-2013. Nerve tissue lesions may occur during various dental and routine surgical procedures, resulting in paresthesia. Laser therapy has been shown to be able to accelerate and enhance the regeneration of the affected nerve tissue; however, there are few studies in the literature that evaluate the effects of treatment with low-power laser on neural changes after orthognathic or minor oral surgeries. A total of 125 clinical records were included, and the data on gender, age, origin of the lesion, nerve, interval between surgery and onset of laser therapy, frequency of laser irradiation (one or two times per week), final evolution, and if there was a need to change the irradiation protocol, were all recorded. These data were related to the recovery of sensitivity in the affected nerve area. Descriptive analyses and modeling for analysis of categorical data (α=5%) were performed. The results from both analyses showed that the recovery of sensitivity was correlated with patient age (p=0.015) and interval between surgery and onset of laser therapy (p=0.002). Within the limits of this retrospective study, it was found that low- power laser therapy with beam emission band in the infrared spectrum (808 nm) can positively affect the recovery of sensitivity after orthognathic or minor oral surgeries.

    The benefit of ankle arthroplasty compared to arthrodesis continues to be debated, but the quality of life after these two interventions has rarely been assessed. We conducted a case-control study to compare quality of life and functional and athletic ability. Functional results, athletic ability, and quality of life after total ankle arthroplasty (TAA) are better than after ankle arthrodesis. Two continuous series of 59 TAAs and 46 arthrodeses (operated on between 1997 and 2009) were evaluated retrospectively using a questionnaire including the functional items of the AOFAS score, the Foot Function Index (FFI) score, the Foot Ankle Ability Measure (FAAM), and the SF-36. Eighty-three responses (79% of the overall series) were matched in two groups: 32 TAAs [age at the intervention, 51.4years (range, 21-63years); follow-up, 52.2months (range, 30-146months); age at revision, 55.8years (range, 26-67years); BMI, 27.7 (range, 21.7-36.7)] and 22 arthrodeses [age at intervention, 50.1years (range, 24-72years); follow-up 57.9months (range, 12-147months); age at revision 54.9 years (range, 31-75years); BMI, 26.8 (range, 17.6-37)] (NS on all items between the two groups). The pain results were better after TAA, but with no statistically significant difference: AOFAS pain, (/40) 28.1±8.2 vs. 24.5±9.6; FFI pain, 16.6±18.8 vs. 24.3±21.5. The overall FFI score (/100) was better (P=0.048) after TAA (16.2±16.5 vs. 24.8±18.2). The overall mean athletic level compared to the state prior to the injury was relatively low in both groups, but significantly (p=0.007) higher in the TAA group: FAAM sports score (/100), 49.5±24.4 vs. 29.8±26.2. The quality-of-life scores, SF-36 physical health, mental health, and general health were not significantly different after TAA and arthrodesis: mental health score, 63.1±14.7 vs. 57.8±21.5; physical health score, 61.3±17.8 vs. 53.7±23.9, overall score, 63.2±16.4 vs. 55.9±23.5.

    Highlights: •Infant cases frequently show a diffuse increase in the concentration of lung fields on post-mortem computed tomography (PMCT). •In this study, twenty-two of the thirty sudden infant death cases showed increasing concentration in the entire lung field. •Based on the autopsy results, the lungs simply collapsed and no other abnormal lung findings were identified. •The radiologist should not consider increasing concentration in all lung fields as simply a pulmonary disorder when diagnosing the cause of infant death using PMCT. -- Abstract: Objectives: Infant cases frequently show a diffuse increase in the concentration of lung fields on post-mortem computed tomography (PMCT). However, the lungs often show simply atelectasis at autopsy in the absence of any other abnormal changes. Thus, we retrospectively reviewed the PMCT findings of lungs following sudden infant death and correlated them with the autopsy results. Materials and methods: We retrospectively reviewed infant cases (0 year) who had undergone PMCT and a forensic autopsy at our institution between May 2009 and June 2013. Lung opacities were classified according to their type; consolidation, ground-glass opacity and mixed, as well as distribution; bilateral diffuse and areas of sparing. Statistical analysis was performed to assess the relationships among lung opacities, causes of death and resuscitation attempt. Results: Thirty infant cases were selected, which included 22 sudden and unexplained deaths and 8 other causes of death. Resuscitation was attempted in 22 of 30 cases. Bilateral diffuse opacities were observed in 21 of the 30 cases. Of the 21 cases, 18 were sudden and unexplained deaths. Areas of sparing were observed in 4 sudden and unexplained deaths and 5 other causes of death. Distribution of opacities was not significantly associated with causes of death or resuscitation attempt. The 21 cases with bilateral diffuse opacities included 6 consolidations (4 sudden and unexplained

    The medical records of 100 cats with distal aortic thromboembolism were reviewed. The average age was 7.7 years, with the neutered male being the most common signalment (63%). Evidence of preexisting cardiac disease was noted in 11% of the cases. A murmur or arrhythmia was noted in 57% of the cases on presentation. Frequent laboratory abnormalities included elevations in blood glucose, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, and creatinine. Radiographic and electrocardiographic abnormalities were common (89% and 85%, respectively). The most frequent, underlying disease was hypertrophic feline cardiomyopathy (58%), with the left atrial size (as measured by M-mode) significantly increased in the majority of cases (mean left atrial-to-aortic ratio, 2.08). The average, long-term survival in the 37% of cases which survived the initial thromboembolic episode was 11.5 months. The remaining cases either died (28%) or were euthanized (35%)

    AIM: This study focused on children aged zero to six years with suspected single-dose paracetamol poisoning, which has not been investigated in Denmark. We evaluated the incidence of liver injuries and the use of activated charcoal and N-acetylcysteine treatment. METHODS: Our retrospective study.......67 ± 1.05 years. Activated charcoal treatment was given in 87% of cases, but only 15% of the children received treatment within one hour of the suspected paracetamol poisoning. Although 80% of the children received N-acetylcysteine treatment, only one case (0.5%) had a toxic plasma paracetamol level...... children aged zero to six years with suspected paracetamol poisoning. Vomiting or abdominal pain was associated with elevated plasma paracetamol levels. No liver injuries were reported....

  13. Clinical signs in the Wernicke-Korsakoff complex: a retrospective analysis of 131 cases diagnosed at necropsy.

    A recent necropsy study has shown that 80% of patients with the Wernicke-Korsakoff syndrome were not diagnosed as such during life. Review of the clinical signs of these cases revealed that only 16% had the classical clinical triad and 19% had no documented clinical signs. The incidence of clinical signs in this and other retrospective pathological studies is very different from that of prospective clinical studies. This discrepancy may relate to "missed" clinical signs but the magnitude of the difference suggests that at least some cases of the Wernicke-Korsakoff syndrome may be the end result of repeated subclinical episodes of vitamin B1 deficiency. In order to make the diagnosis, clinicians must maintain a high index of suspicion in the "at risk" group of patients, particularly alcoholics. Investigations of thiamine status may be helpful and if the diagnosis is suspected, parenteral thiamine should be given. PMID:3701343

    The number of tattooed people in Germany has constantly grown over the past few years. The present study deals with the question if this social trend can be seen in foren- sic autopsy cases as well. In a retrospective study, forensic autopsy cases of two periods (1990-1994 and 2010-2014) have been reviewed and statistically analyzed. Comparison of the two periods revealed a significant increase in tattooed individuals, especially in the female subgroup. Between 2010 and 2014, 14.2 % of the deceased showed tattoos. There are significant differences in the frequency and localization of tattoos dependent on age and sex. About 50 % of the tattooed deceased showed tattoos on body sites that are visible for other persons in everyday life. The resulting value of tattoos for the purpose of identifying unknown bodies is discussed and illustrated.

    Minimal invasive plate osteosynthesis (MIPO) is one of the most important techniques in the treatment for humeral shaft fractures. This study was performed to evaluate the efficacy of MIPO technique for the treatment for humeral shaft fractures. We retrospectively evaluated 128 cases with humeral shaft fractures that were treated with MIPO technique from March 2005 to August 2008. All the patients were followed up by routine radiological imaging and clinical examinations. Constant-Murley score and HSS elbow joint score were used to evaluate the treatment outcome. The average duration of the surgery was 60 min (range 40-95 min) without blood transfusion. All fractures healed without infection. All cases recovered carrying angle except four cases with 10°-15° cubitus varus. After the average follow-up of 23 (13-38) months, satisfactory function was achieved according to Constant-Murley score and HSS elbow joint score. Constant-Murley score was 80 on average (range 68-91). According to HSS elbow joint score, there were 123 cases of excellent clinical outcome and five cases of effective outcome. It seems to be a safe and effective method for managing humeral shaft fractures with MIPO technique.

    Full Text Available Background: Although the association of urinary lithiasis and urinary tract malformation is not rare, their management poses challenges. The aim of this study was to evaluate the relationship between urolithiasis and malformations of the urinary system. There were 34 patients (19 males and 15 females with a mean age of 4.8 years (range, 2 months to 14 years. All patients had urinary lithiasis with a urinary tract malformation. Abdominal pain was the most frequent clinical symptom (38%. Urinary infection was found in 7 patients (21% and macroscopic haematuria was present in 10 patients (29%. The most frequent urinary tract malformations were megaureter (8 cases, uretero-pelvic junction obstruction (7 cases and vesico-ureteric reflux (8 cases, but its malformative origin could not be confirmed. Treatment consisted of lithiasis extraction in 32 cases associated with specific treatment of the uropathy in 27 cases. Postoperative outcome was uneventful in all cases. In fact, urinary lithiasis and urinary tract malformation association is not rare. Indeed, 9-34% of urinary lithiasis are noted to be associated with urinary tract malformation. Positive diagnosis relies specifically on kidney ultrasound, intravenous urography, and urethrocystography. Treatment depends on the type of urinary tract malformation, localisation and size of the urinary lithiasis. Conclusion: In conclusion, urinary lithiasis and urinary tract malformation association is a frequent eventuality. Surgical intervention is the usual mode of treatment.

    Full Text Available Objective: To compare pre- and post-therapy symptom scores reported on the National Institute of Health Chronic Prostatitis Symptom Index (NIHCPSI after trans-rectal antibiotic injections therapy for men suffering from chronic prostatitis. Materials and methods: Retrospective analysis of NIHCPSI symptom scores obtained from chart reviews of 77 treated males suffering from chronic prostatitis before and after trans rectal injections for the treatment of chronic prostatitis. Results: Most patients reported a 40% to 60% improvement in symptom scores. In subgroups comparing scores in patients with less than 5 injections, the improvement was less than in patients who received 10 or more injections. Patients’ responses after a shorter (3 months follow up showed better pain scores than patient’s scores after longer, over one-year or more, follow- up periods. Conclusion: Our findings show that direct antibiotic injection for chronic prostatitis is a viable addition to standard therapies. Improvements in symptom scores are long lasting. Discomfort is minimal and side effects are rare and avoidable

    This retrospective clinical study aimed to assess patient’s satisfaction with removable partial dentures (RPDs), as retention, chewing ability, aesthetics during the observation period. Material and Methods: A total of 63 patients with RPDs, participated in this study. The following data was collected: Kennedy classification, denture design, denture support, satisfaction and success of RPD. Result: The results showed that 73.6% of patients were wearing RPD for the first time and were finally satisfied. According to the denture support of RPDs, clasp-retained quadrangular RPDs were 100% effective, followed by triangular dental support 81% and linear dental support 47.7%. Comparison of RPDs with attachment with RPDs with claps assessed through Fisher exact test, confirmed statistically significant difference (P=0.008), despite retention; however, chewing ability and aesthetics showed no statistically significant difference with X 2 test on patient’s satisfaction with RPD with or without attachment. Conclusion: Patients often would prefer not showing the anterior buccal clasps of RPD, therefore are generally satisfied more with RPD with attachment based on level of retention, chewing ability and aesthetics.

    Full Text Available Objective This study aimed to assess the clinicoradiological features and treatment outcome of intracranial dissecting aneurysms (IDAs in childhood.Methods We conducted a retrospective study of pediatric patients who were treated for spontaneous IDAs in our institute between January 2010 and December 2015. The clinical presentation, aneurysm characteristics, treatment modality, and outcome were studied. Results We studied 26 pediatric patients (mean age, 13.4 years; range, 4–18 years with 31 IDAs who comprised 6.9% of all IDA patients treated during the same period. Seventeen (65.4% patients were male and nine (34.6% were female. The incidence of large (≥10mm in size or giant aneurysms (≥25mm in size was 65.5%. Twenty-one (80.8% patients underwent endovascular or surgical treatment and five (19.2% received conservative treatment. Perioperative complications occurred in three patients, in whom two eventually recovered completely with a Glasgow Outcome Scale (GOS score of 5 and one partially recovered with a GOS score 4. Overall, 25 (96.2% patients had a favorable outcome and one (3.8% had an unfavorable outcome at a mean follow-up of 22.8 months (range, 6–60 months.Conclusions Pediatric IDAs are rare. In this series, endovascular management was a relatively safe and effective method of treatment for pediatric IDAs. However, continued follow-up is required because of the possibility of aneurysm recurrence and de novo aneurysm formation after treatment.

    Objective To report the echocardiographic evaluation of 103 infants with presumed congenital Zika syndrome. Methods An observational retrospective study was performed at Instituto de Medicina Integral Prof. Fernando Figueira (IMIP), Recife, Brazil. 103 infants with presumed congenital Zika syndrome. All infants had microcephaly and head computed tomography findings compatible with congenital Zika syndrome. Zika IgM antibody was detected in cerebrospinal fluid samples of 23 infants. In 80 infants, the test was not performed because it was not available at that time. All infants had negative serology for HIV, syphilis, rubella, cytomegalovirus and toxoplasmosis. A complete transthoracic two-dimensional, M-mode, continuous wave and pulsed wave Doppler and color Doppler echocardiographic (PHILIPS HD11XE or HD15) examination was performed on all infants. Results 14/103 (13.5%) echocardiograms were compatible with congenital heart disease: 5 with an ostium secundum atrial septal defect, 8 had a hemodynamically insignificant small apical muscular ventricular septal defect and one infant with dyspnea had a large membranous ventricular septal defect. The echocardiograms considered normal included 45 infants with a persistent foramen ovale and 16 with a minimum patent ductus arteriosus. Conclusions Preliminarily this study suggests that congenital Zika syndrome may be associated with an increase prevalence of congenital heart disease. However the types of defects noted were septal defects, a proportion of which would not be hemodynamically significant. PMID:28426680

    To investigate the diagnostic value of contrast-enhanced computed tomography (CT) for the prediction of deep neck abscesses in different deep neck spaces and to evaluate the false-positive results. We retrospectively analysed the clinical charts, CT examinations, surgical findings, bacteriology, pathological examinations and complications of hospitalised patients with a diagnosis of deep neck abscess from 2004 to 2010. The positive predictive values (PPV) for the prediction of abscesses by CT scan in different deep neck spaces were calculated individually on the basis of surgical findings. A total of 162 patients were included in this study. All patients received both intravenous antibiotics and surgical drainage. The parapharyngeal space was the most commonly involved space. The overall PPV for the prediction of deep neck abscess with contrast-enhanced CT was 79.6%. The PPV was 91.3% when more than one deep neck space was involved but only 50.0% in patients with isolated retropharyngeal abscesses. In the false-positive group, cellulitis was the most common final result, followed by cystic degeneration of cervical metastases. Five specimens taken intra-operatively revealed malignancy and four of these were not infected. There are some limitations affecting the differentiation of abscesses and cellulitis, particularly in the retropharyngeal space. A central necrotic cervical metastatic lymph node may sometimes also mimic a simple pyogenic deep neck abscess on both clinical pictures and CT images. Routine biopsy of the tissue must be performed during surgical drainage.

    Cement is increasingly used in the construction industry, but the occurrence of cement burns is rarely reported. This retrospective study concerns patients treated for cement burns in our unit between 1997 and 2002. Eighteen patients 18-64 years of age, treated previously in our unit for cement burns, were interviewed by telephone for evaluation. The mean time since treatment was 39 months. Burns were predominantly seen on the lower limbs, and a third occurred during an accident on the job. All deep burns were excised, and 16 patients received grafts. Mean hospital stay was 10 days, and mean sick leave 2 months. Our study indicated that all patients were poorly informed about cement-related risks. Surgical treatment of full-thickness cement burns at diagnosis enables rapid healing with a minimum of sequelae and reduces the high socioeconomic costs resulting from these lesions. This study indicates once again the need to improve preventive measures; which are very often inadequate because of lack of awareness of risks.

    Full Text Available Coronary artery disease is one of the leading causes of morbidity and mortality especially in the indusirialzcd societies. This retrospective study was carried out on 385 patients who were referred to Shariati and Jamaran Hospitals from 1992 till 1997 and who underwent coronaty artery bypass grafting. The objective was to obtain a descriptive analysis of the important factors in this population and to draw a comparison betweent the two genders and to draw genders regarding these variables. The data were obtained from patients' files, angiography and operation notes; 82.9% of the study population were of male. The mean age of women was higher than men by 2.2years. The most common risk factors among the male gender were found to be smoking, hyperlipedemia, hypercholesterolemia and hypertension. Except for smoking which was omitted in women, all other risk factors showed a comparative low prevalence in this gender. Most patients (93.37% fell in group II and III of functional class as per NYHA classification and the most frequent signs and symptoms on admission being chest pain (81.5% and dyspnea (11.2%. The affected vessels in order of frequency were the left anterior descending, the right coronary and the circumflex arteries respectively. The average number of grafts utilized were 3 in the entire population. Overall mortality recorded was 2.1%.

    The authors report on the retrospective analysis of 19 patients with primary cerebral germ cell tumors which were treated between 1965 and 1993. Median age is 18 years (extremes: 16-55 years). There were 16 men and three women. The location of the primary tumor was the pineal area in six patients, suprasellar and hypothalamic area in five patients and other areas in eight patients. The histological pattern was non seminoma in six patients, dysgerminoma in eight; however no histological sample was obtained in five patients who did not have any particular characteristics (either cytological abnormalities or elevated tumor marker level). Three patients were treated by surgery only, eight patients received exclusive radiotherapy and eight patients had first line chemotherapy and further cranial irradiation. One was lost to follow up. Six of eight assessable patients with dysgerminoma are alive with non evolutive disease (NED) after 15 to 176 month of follow-up. One out of five assessable patients with non seminomatous tumor in NED (163 month of follow-up). Finally all five patients who have no histological subtyping are alive with NED at 24 to 138 months. The standard treatment of dysgerminoma is currently first line chemotherapy followed by relatively low-dose and limited irradiation; the standard treatment of non-seminomatous cerebral germ cell tumor is chemotherapy, the study of which is warranted with the aim to decrease the toxicity and to increase the efficacy.

    Objective: To evaluate the clinical characteristics and etiologies of central diabetes insipidus (CDI). Methods: The clinical data of 230 patients with CDI in the Department of Endocrinology of Chinese PLA General Hospital from 2008 June to 2014 December were collected and analyzed retrospectively. Results: The three most common causes of CDI were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. Among all the CDI, the idiopathic CDI accounted for 37.48%. There were significant differences in age onset and gender distribution among the different causes of CDI. The patients with intracranial germ cell tumors [age of onset(19.2±10.2) years] were younger than the other types of CDI. Germ cell tumors patients were more common in male, and lymphocytic hypophysitis patients were more common in female. The most frequent abnormality of anterior pituitary in patients with CDI was growth hormone deficiency, followed by hypogonadism, adrenal insufficiency and hypothyroidism. The dysfunction of thyroid axis and adrenal axis in patients with germ cell tumor was more common than those in patients with idiopathic and lymphocytic hypophysitis. Conclusions: The most common causes of central diabetes insipidus were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. There were differences in age of onset, gender distribution and abnormal production of anterior pituitary hormones among all causes of CDI patients.

    To evaluate the discriminative value of conventional magnetic resonance imaging between benign and malignant palatal tumors. Conventional magnetic resonance imaging features of 130 patients with palatal tumors confirmed by histopathologic examination were retrospectively reviewed. Clinical data and imaging findings were assessed between benign and malignant tumors and between benign and low-grade malignant salivary gland tumors. The variables that were significant in differentiating benign from malignant lesions were further identified using logistic regression analysis. Moreover, imaging features of each common palatal histologic entity were statistically analyzed with the rest of the tumors to define their typical imaging features. Older age, partially defined and ill-defined margins, and absence of a capsule were highly suggestive of malignant palatal tumors, especially ill-defined margins (β = 6.400). The precision in determining malignant palatal tumors achieved a sensitivity of 92.8% and a specificity of 85.6%. In addition, irregular shape, ill-defined margins, lack of a capsule, perineural spread, and invasion of surrounding structures were more often associated with low-grade malignant salivary gland tumors. Conventional magnetic resonance imaging is useful for differentiating benign from malignant palatal tumors as well as benign salivary gland tumors from low-grade salivary gland malignancies.

    Percutaneous endoscopic colostomy (PEC) is a technique derived from percutaneous endoscopic gastrostomy. When conservative treatment of chronic obstipation fails, colon irrigation via PEC seems less invasive than surgical interventions. However, previous studies have noted high complication rates of PEC, mostly related to infections. Our aim was to report our experiences with PEC in patients with chronic refractory constipation. Retrospective analysis of all patients who underwent PEC for refractory constipation in our secondary referral hospital between 2009 and 2016. Twelve patients received a PEC for chronic, refractory constipation. Short-term efficacy for relief of constipation symptoms was good in 8 patients and moderate in 4 patients. Two patients had the PEC removed because of spontaneous improvement of constipation. Three patients, who initially noticed a positive effect, preferred an ileostomy over PEC after 1-5 years. One PEC was removed because of an abscess. Long-term efficacy is 50%: 6 patients still use their PEC after 3.3 years of follow-up. No mortality occurred. PEC offers a technically easily feasible and safe treatment option for patients with chronic constipation not responding to conventional therapy. Long-term efficacy of PEC in our patients is 50%. © 2017 John Wiley & Sons Ltd.

    Ingestion of wilted red maple leaves by horses can result in severe hemolytic anemia and methemoglobinemia. Little is known about what factors influence the outcome of red maple leaf toxicosis in horses. Our hypothesis was that physical examination findings, clinicopathologic variables or therapeutic modalities may predict outcome in horses with red maple leaf toxicity. Horses with red maple leaf toxicosis presented to referral hospitals in the southeast region of the United States. A multi-institutional retrospective study was designed to identify factors that predict mortality in horses with red maple toxicosis. Thirty-two horses with red maple toxicosis were identified, 19 of which died. Twenty-nine horses presented with anemia and 24 had clinicopathologic evidence of systemic inflammation. Renal insufficiency was identified in 12/30 (41%) horses. Laminitis (9/28) and colic (13/30) also were identified in horses with red maple toxicosis, but development of these 2 conditions did not have a negative effect on short-term survival. Horses with red maple toxicosis that survived to discharge were likely to have developed pyrexia during hospitalization (P = .030). Horses that were treated with a corticosteroid had a significantly increased likelihood of death (P = .045). There was no significant relationship between initial serum hemoglobin concentration, methemoglobin concentration, or percentage methemoglobin and mortality in this horse series. This study suggests that information obtained on initial examination cannot be used to accurately predict survival in horses with red maple toxicosis, but horses that receive corticosteroids are unlikely to survive.

    The purpose of this retrospective study was to describe the biological behaviour of canine mandibular osteosarcoma (OSA) and to examine factors for their impact on metastasis-free interval (MFI) and survival time (ST). Records from dogs treated with mandibulectomy for OSA (1999-2007) were reviewed. Archived tumour samples were evaluated for mitotic index (MI) and tumour grade. Fifty dogs were included, 21 received chemotherapy. Twenty-nine dogs (58%) developed metastatic disease. The median MFI was 627 days, and median ST was 525 days. In univariate analysis MI > 40 was prognostic for decreased MFI and ST. Grade also influenced MFI and ST, with 5/21 (24%) dogs with grade II/III tumours metastasis-free at one year versus 16/22 (72%) dogs with grade I tumours (P = 0.002); and 5/21 (24%) dogs with grade II/III tumours alive versus 17/22 (77%) dogs with grade I tumours (P = 0.001). In multivariate analysis, histological grade and adjuvant chemotherapy were prognostic for MFI and ST. © 2013 Blackwell Publishing Ltd.

    To review the association between clinical signs and diagnostic findings and the survival time of dogs with dilated cardiomyopathy (DCM), and any influence of treatment prescribed. A retrospective observational study of 367 dogs with DCM. Survival times until death or euthanasia for cardiac reasons were analysed using the Kaplan-Meier method plus univariate and multivariate Cox proportional hazards models. Two-tailed P values less than 0.05 were considered statistically significant. In the multivariate model, left ventricular diameter (LVDs)-index (P=0.0067), presence of pulmonary oedema on radiography (P=0.043), presence of ventricular premature complexes (VPCs) (P=0.0012), higher plasma creatinine (P=0.0002), lower plasma protein (P=0.029) and great Dane breed (P=0.0003) were negatively associated with survival. Most dogs were treated with angiotensin-converting enzyme inhibitors (93%) or furosemide (86%), and many received digoxin (50%) and/or pimobendan (30%). Thirteen dogs were lost to follow-up. No conclusions could be made in this study on the association between use of drugs and survival. The LVDs-index was the single best variable for assessing the prognosis in this group of dogs with DCM. Other variables that were negatively associated with survival were presence of pulmonary oedema on radiography, presence of VPCs, higher plasma creatinine, lower plasma protein and great Dane breed.

    To describe the clinical presentation and outcome of known attacks in client-owned dogs caused by the common coyote, Canis latrans. Retrospective observational study. Private referral hospital. One hundred fifty-four client-owned dogs known to be attacked by coyotes. None. Records from a private referral hospital from May 1997 through December 2012 were reviewed. Time of day and month/season of year, signalment, body temperature, heart rate, respiratory rate, body weight, location and severity of wounds inflicted, common injuries, length of hospitalization, necessity of surgical wound repair under anesthesia, antimicrobial use and mortality were recorded. Eighty-six percent of dogs presenting following coyote attack weighed Dogs with bite wounds to the thorax had the highest mortality at 21.3%. Criteria for systemic inflammatory response syndrome (SIRS) based on admission vital signs were met in 58.8% of dogs and the presence of SIRS was significantly associated with mortality (P hernia (9/154; 5.8%), and abdominal penetrating wounds (8/146; 5.5%). Dogs dogs are a problem in Southern California and are associated with substantial morbidity and mortality, especially in dogs with wounds to the thorax. Aggressive management involving surgical wound repair was associated with survival to discharge. © Veterinary Emergency and Critical Care Society 2017.

    Introduction: In order for a diagnosis of Occupational Hearing Loss (BK-no. 2301) to be made certain criteria must be fulfilled to establish that the hearing loss is occupational in origin. This work compares 2 groups, those who fulfil the criteria (BKE) and those who do not (BKNE). Methods: A 100 consecutive reports ("Lärmgutachten BK-no. 2301") written by the authors were examined retrospectively. These recorded audiometric examination, an analysis of any tinnitus and noise exposure plus use of hearing protection. Pre- and post-noise exposure status together with an expert assessment of work limitations was made to produce a 7 point score. Results: 67% of the group fulfilled the conditions for occupational hearing loss (9% were entitled to compensation). In the BKE group 82% showed typical audiometric signs of noise damage with 75% of them fulfilling at least 6 criteria of occupational disease no. 2301. Tinnitus typical for noise exposure was found in 26%. Discussion: A 7 point score could be useful in the future as a method of helping distinguish hearing loss and tinnitus from occupational as opposed to other causes. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Perioperative chemotherapy increases the overall and progression-free survival of patients suffering from resectable adenocarcinomas of the lower esophagus, gastroesophageal junction and stomach (GEC. Comparing different chemotherapy regimens platin-based protocols with 5-fluorouracil (5-FU/calcium folinate (CF or oral fluoropyrimidines were favorable in terms of efficacy and side-effects. However, there is no consensus which regimen is the most efficacious.42 consecutive patients with resectable GEC (UICC II and III were treated with 3 pre- and postoperative chemotherapy cycles each consisting of epirubicin, oxaliplatin and capecitabine (EOX. We analyzed the overall survival, progression-free survival and toxicity retrospectively in comparison to published data.The median overall survival in our cohort was 29 months and the progression-free survival was 17 months. The most frequent grade 3 and 4 toxicities during preoperative chemotherapy were diarrhea (16.7%, leukocytopenia (9.5% and nausea (9.5%; overall 38.1% of our patients suffered from grade 3 or 4 toxicity. Surgery was carried out in 83% of our patients, 69% of those achieved R0 resection.Comparing our data with the results of previously published randomized trials EOX is at least non-inferior with regard to overall survival, progression-free survival and toxicity. In conclusion, EOX is an appropriate perioperative therapy for patients with resectable GEC.

All infants had microcephaly and head computed tomography findings compatible with congenital Zika syndrome. Zika IgM antibody was detected in cerebrospinal fluid samples of 23 infants. In 80 infants, the test was not performed because it was not available at that time. All infants had negative serology for HIV, syphilis, rubella, cytomegalovirus and toxoplasmosis. A complete transthoracic two-dimensional, M-mode, continuous wave and pulsed wave Doppler and color Doppler echocardiographic (PHILIPS HD11XE or HD15 examination was performed on all infants.14/103 (13.5% echocardiograms were compatible with congenital heart disease: 5 with an ostium secundum atrial septal defect, 8 had a hemodynamically insignificant small apical muscular ventricular septal defect and one infant with dyspnea had a large membranous ventricular septal defect. The echocardiograms considered normal included 45 infants with a persistent foramen ovale and 16 with a minimum patent ductus arteriosus.Preliminarily this study suggests that congenital Zika syndrome may be associated with an increase prevalence of congenital heart disease. However the types of defects noted were septal defects, a proportion of which would not be hemodynamically significant.

    A retrospective review of 396 patients with primary hyperparathyroidism (pHPT) treated surgically revealed a past history of neck external irradiation in 14 patients (35%). The mean interval between radiation exposure and the diagnosis of pHPT was 41 years (range, 31-49 years). All of the patients were women who had been exposed to radiation more than 31 years before. There was a significant difference in the male:female ratio of affected patients (p<0.001). The parathyroid histology was adenoma in 13 patients and carcinoma in one. In ten patients, normal parathyroid gland biopsies were undertaken. Among normal parathyroid glands from two patients, there were nodular lesions. Thirteen (93%) of the 14 patients who had undergone neck irradiation had thyroid nodular disease. In contrast, only 98 (26%) of the 382 patients who had not undergone neck external irradiation had thyroid nodular disease, and the difference between the two groups was significant (p<0.001). Neck irradiation has been shown to increase the risk of parathyroid and thyroid nodular diseases. If neck exploration is necessary in a patient who has received neck irradiation, both the thyroid and parathyroid glands should be carefully evaluated before and during surgery. (author)

    Full Text Available Abstract Background Carcinoma of the gallbladder (GBC clinically mimics benign gallbladder diseases and often escapes detection until advanced stage. Despite the frequency of cholecystectomy, diagnosis of GBC remains problematic in many situations. We sought to identify pathologic features that contribute to the difficulty in recognition of GBC. Methods We identified 23 patients (ranged from 45 to 86 years, male to female ratio 1:4.5 with carcinoma involving the gallbladder referred to an academic medical center over a period of 10 years for study. This includes 10 cases of primary GBC, 6 cases of metastatic tumor to gallbladder, 6 cases of directly invasive adenocarcinoma arising elsewhere in the biliary tree, and one case of unidentified origin adenocarcinoma. Primary tumors include adenocarcinoma not otherwise specified (NOS in 6 cases, papillary adenocarcinoma in 2 cases, and single cases of undifferentiated carcinoma and combined adenocarcinoma and neuroendocrine carcinoma (NEC. Metastatic tumors to gallbladder were from a wide range of primary sites, predominantly the gastrointestinal tract. Results These cases illustrate seven potential pitfalls which can be encountered. These include: 1 mistakenly making a diagnosis of adenocarcinoma of gallbladder when only benign lesions such as deeply penetrating Rokitansky-Aschoff sinuses are present (overdiagnosis, 2 misdiagnosing well-differentiated invasive carcinoma with minimal disease as benign disease (underdiagnosis, 3 differentiating between primary NEC of gallbladder and metastasis, 4 confusing primary mucinous adenocarcinoma of gallbladder with pseudomyxoma peritonei from a low grade appendiceal neoplasm disseminated to gallbladder, 5 confusing gangrenous necrosis related to cholecystitis with geographic tumoral necrosis, 6 undersampling early, grossly occult disease, and 7 misinterpreting extracellular mucin pools.

    In biomarker discovery studies, uncertainty associated with case and control labels is often overlooked. By omitting to take into account label uncertainty, model parameters and the predictive risk can become biased, sometimes severely. The most common situation is when the control set contains an unknown number of undiagnosed, or future, cases. This has a marked impact in situations where the model needs to be well-calibrated, e.g., when the prediction performance of a biomarker panel is evaluated. Failing to account for class label uncertainty may lead to underestimation of classification performance and bias in parameter estimates. This can further impact on meta-analysis for combining evidence from multiple studies. Using a simulation study, we outline how conventional statistical models can be modified to address class label uncertainty leading to well-calibrated prediction performance estimates and reduced bias in meta-analysis. We focus on the problem of mislabeled control subjects in case-control studies, i.e., when some of the control subjects are undiagnosed cases, although the procedures we report are generic. The uncertainty in control status is a particular situation common in biomarker discovery studies in the context of genomic and molecular epidemiology, where control subjects are commonly sampled from the general population with an established expected disease incidence rate.

    Musculoskeletal allografts are now commonly used. To decrease the potential risks of transmission of pathogenic bacteria, fungi, or viruses to the transplant recipients, certain issues regarding the management of patients who receive contaminated allografts need to be addressed. We aimed to clarify the incidence and extent of disease transmission from allografts by analyzing the allografting procedures performed in the bone bank of our hospital over the past 20 years. We retrospectively reviewed the data from our allograft registry center on 3979 allografts that were implanted in 3193 recipients throughout a period of two decades, from July 1991 to June 2011. The source of the allografts, results of all screening tests, dates of harvesting and implantation, and recipients of all allografts were checked. With the help of the Center for Infection Control of our hospital, a strict prospective, hospital-wide, on-site surveillance was conducted, and every patient with healthcare-associated infection was identified. Fisher's exact test was used to compare the infection rate between recipients with sterile allografts and those with contaminated allografts. The overall discard and infection rates were, respectively, 23% and 1.3% in the first decade (1991-2001); and 18.4% and 1.25% in the second decade (2001-2011). The infection rate of contaminated allograft recipients was significantly higher than that of sterile allograft recipients (10% vs. 1.15%, P bank are comparable with those of international bone banks. Strict allograft processing and adequate prophylactic use of antibiotics are critical to prevent infection and disease transmission in such cases.

    2011-01-01

    Objective: The effect of radiotherapy in context of a plantar fasciitis in order to reduce pain was evaluated in this retrospective study. Patients and methods: The data of 188 patients who suffered of heel spur pain and who were irradiated in the period from 1994 to 2009 were evaluated in this study. All of them had at least one follow up examination after radiatiotherapy. The mean age amounted to 57 years. 76.5% of the patients were female. All patients described a local pain which was the basis for the indication. 74.4 % of the patients described pain especially under stress. The duration of anamnesis was averaged as follows: 15 % of the patients had pain for some weeks to 3 months, 43 % for 4 to 6 months, 28% even for 7 to 12 months. The period of medical history was longer than 12 months for 12 % of the patients in this study. 122 of 188 patients received orthopedic arch support (shoe inlays) as first therapy method. Most of the patients were irradiated using regular lateral opposing fields with photons of the energy 4 MV and 6 MV of a linear accelerator, applying a total dose of 6Gy in 6 fractions to 1,0Gy twice weekly. Only one patient was irradiated using a Co 60 machine. The acquisition of data regarding the effect was performed on the last day of the radiotherapy and in 3 to 6 monthly follow ups. Additionally the doctors who attended the patients beyond the radiotherapy received a special questionnaire about the pain reduction, so that the follow up data could be completed. Results: On the last day of radiotherapy 120/188 patients (63,8%)reported an improvement of pain reduction, 7/188 patients (3,7%) absence of pain. For 52/188 patients (27.6 %) pain remained constant. At the second follow up examination after in the median 100 days the effect of radiotherapy of 165 patients could be evaluated, 43/165 patients (26 %) were pain free, 79/165 patients (47,8 %) reported an obvious pain reduction, and for 33/165 patients there was no pain improvement.

    Full Text Available Background: Data on Severe cutaneous drug reactions (CADRs are not common among in sub-Saharan Africa children. The purpose of this study was to document the clinical, etiological and evolutionary aspects of Severe CDRs in children hospitalized at the dermatology department of university hospitals of Conakry. Material and Methods: Retrospective study, conducted from 1 January 2000 to 31 December 2014. Were included all children aged 0-17 years hospitalized for severe CARDs. The data collected were Socio-demographic, clinical, para-clinical and evolution variables. The data was entered and analyzed using the Excel 8.0 software. Results: During a study period, 4437 patients of all ages was hospitalized in dermatology department. 35 patients were included with an average age of 11.3 years and a sex ratio of 1.5. The main clinical patterns were: Stevens Johnson syndrome 37.14% (13/35 Lyell syndrome 25.71 % and generalized bullous fixed eruption 22.85%. The drug was identified as 32 patients (91.42%: Sulfadoxine–Pyriméthamine 40.62%, cotrimoxazole 21.85%, nevirapin 12.5%, ampicillin 6.25%, traditional Pharmacopoeia 6.25% and griseofulin 3.12%. It was taken following self-medication in 14 patients, including a parental initiative in 9 patients. 7 patients had a history of drug allergy and 4 were HIV positive. We recorded 5 deaths. Conclusion: Our study confirms the rarity of severe CADRs in children. The importance of the sulfadoxine-pyrimethamine in the occurrence of severe CADRs in children is the particularity of our series.

    To study the epidemiologic, clinical and histological aspects of eyelid carcinomas in our context, and to evaluate our surgical management on an oncological, functional and aesthetic level. This work is a retrospective bicentric study extended over a 5-year period between January 2009 and December 2013, including 64 patients with eyelid carcinoma undergoing surgery in the Plastic and Reconstructive Surgery Department at the Avicenne University Hospital of Rabat and in the ENT/Head and Neck Surgery Department at the Hassan II University Hospital of Fez. The study included 25 men and 39 women with a mean age of 60.6 ± 15.33 years. Advanced age and chronic sun exposure were the most important risk factors. The most commonly involved site was the lower eyelid (53%). Histological examination emphasized the very high prevalence of basal cell carcinoma (90.62%). Surgical treatment was performed in all our patients followed by an extemporaneous and/or standard histological examination of the surgical specimen. Exenteration was performed in one patient with adjuvant radiation therapy. Reconstruction incorporated a variety of techniques, of which total skin graft and Mustardé flap were the most common in our series. Aside from a few complications, the postoperative results were satisfactory for the majority of our patients. Malignant tumors of the eyelids, of which basal cell carcinoma is the most common, pose a therapeutic problem where surgery remains the most utilized treatment option. The best treatment is prevention and diagnosis of early lesions to improve prognosis and to avoid worse outcomes. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    To summarize the signalment, clinical signs, prevalence of decreased blood glucose concentration (BG), prevalence of increased liver values, treatment, and outcome in dogs known to have ingested xylitol. Retrospective study from December 2007 to February 2012 SETTING: Three university teaching hospitals. One hundred ninety-two client-owned dogs with known or suspected xylitol ingestion. None. The median ingested xylitol dose was 0.32 g/kg (range 0.03-3.64 g/kg). Clinical signs were present in 39 (20%) dogs on presentation to the veterinary teaching hospitals. The most common clinical sign was vomiting (n = 25), followed by lethargy (12). The median duration of clinical signs prior to presentation was 93 minutes (range 0-5,040 minutes). Dogs that developed clinical signs ingested a significantly higher dose of xylitol than those that were asymptomatic. Thirty dogs became hypoglycemic (BG ≤ 3.3 mmol/L [60 mg/dL]) at some time point during their hospitalization. When evaluating all dogs, there was a significant difference between the initial and lowest BGs. Thirty dogs had increased alanine aminotransferase activity or total serum bilirubin concentration. Dogs with increases in alanine aminotransferase activity or total serum bilirubin concentration had a significantly lower nadir BG. All dogs survived to discharge and 158 were known to be alive at 28 days. The rest were lost to follow up. The prognosis for dogs evaluated by a veterinarian that ingest lower doses of xylitol and do not develop liver failure is excellent. Dogs ingesting xylitol should be hospitalized and monitored for variations in BG, because BG drops in most dogs following presentation. Additional studies are needed in dogs ingesting higher doses of xylitol before correlations between dose and the development of clinical signs or liver failure can be established. Treatment and prognosis for these dogs warrants further investigation. © Veterinary Emergency and Critical Care Society 2015.

    The aim of this study was to evaluate the effectiveness and safety of emergency cervical cerclage in women with advanced cervical dilatation and bulging of fetal membranes. The study included 158 women who underwent emergency cervical cerclage because of cervix dilatation and protruding membranes in mid-trimester at Sun Yat-sen Memorial Hospital of Sun Yat-sen University. Pregnancy outcomes and pregnancy outcome related to clinical features were analyzed retrospectively. Analysis revealed that the placement of emergency cerclage led to the delivery of live infants with a success rate of 82.28%. The mean interval between cerclage and delivery was 52.16.±26.62 days, with a mean gestation at delivery of 30.3±4.7 weeks and a mean birth weight of 1934.69±570.37 g. No severe maternal complications such as maternal death, hematosepsis, and hysterorrhexis occurred after the operation. Two women (1.25%) had laceration of the cervix, 1 woman (0.61%) suffered pulmonary edema, and 2 women (1.25%) developed deep vein thrombosis (DVT). There were significant correlations between the pregnancy outcome and risk factors, including any presenting symptoms, cervical dilatation, postoperative white blood cell count, and C-reactive protein (CRP) value. No significant difference was found in women with good vs. poor outcome in terms of maternal age and obstetric histories. Emergency cervical cerclage is effective in prolonging pregnancy and improving neonatal outcome in women with cervical incompetence. It should be considered a viable option for women with a dilated cervix in mid-trimester.

    Patent ductus arteriosus (PDA) is one of the most common congenital heart diseases and began to get treated by transcatheter occlusion since 1997 in China. Since then, several devices have been invented for occluding PDA. This study aimed to evaluate the technical feasibility, safety, and efficacy of transcatheter occlusion of PDA with different devices. One thousand five hundred and twenty-six patients (537 boys, 989 girls) with PDA from January 1997 to September 2014 underwent descending aortogram and transcatheter occlusion procedure. We retrospectively analyzed data of these patients, including gender, age, weight, size and morphology of PDA, and devices used in transcatheter occlusion, outcomes, and postoperational complications. Median age and median weight were 4.0 years (range: 0.3-52.0 years old) and 15.3 kg (range: 4.5-91.0 kg), respectively. Mean ductal diameter, aortic ductal diameter, ductal length, and pulmonary artery pressure were 3.50 ± 2.15 mm, 10.08 ± 2.46 mm, 7.49 ± 3.02 mm, and 30.21 ± 17.28 mmHg, respectively. Morphology of PDA assessed by descending aortogram was of type A in 1428 patients, type B in 6 patients, type C in 79 patients, type D in 4 patients, and type E in 9 patients according to the classification of Krichenko. Of all the 1526 patients, 1497 patients underwent transcatheter PDA closure, among which 1492 were successful. Devices used were Amplatzer duct occluder I (ADO I, 1280, 85.8%), Cook detachable coils (116, 7.8%), ADO II (ADO II, 68, 4.6%), muscular VSD occluder (12, 0.8%), and Amplatzer vascular plug (16, 1.0%). Excellent occlusion rates with low complication rates were achieved with all devices regardless of PDA types. With transcatheter occlusion technique and devices developing, more patients with PDA can be treated with transcatheter closure both safely and efficiently.

    Tics are the most frequent abnormal movement in children. A familial history of tics and a personal and familial history of neurobehavioral disturbances are common in children with this abnormality. Tics may seriously compromise daily activities in affected individuals. To identify the characteristics of tics in children and adolescents followed-up in the Neuropediatric Unit of the Hospital Geral de Santo António. We performed a retrospective analysis of patients with tics based on information collected from medical records. The diagnostic criteria of the DSM IV-TR 2000 of the American Psychiatric Association were used. The medical records of 78 children were analyzed, 84.6 % of whom were boys. More than one third of the patients were aged 4 to 8 years old. In 5.1 % of the patients tics developed before the age of 2 years. A familial history of tics, depression and obsessive disorder traits was found in approximately 30 % of patients. The most frequent comorbidity was attention deficit hyperactivity disorder (67.9 %). The occurrence of pediatric autoimmune neuropsychiatric disorders associated with streptococcus infection (PANDAS) was suggested in five patients. In all patients, motor tics occurred before vocal tics. In more than two thirds of the patients, tics were simple. In 59.0 % of the patients, tics were chronic, and in 45.7 % of these met the criteria for Tourette's syndrome. A total of 43.1 % of the patients with chronic tics received pharmacotherapy, risperidone being the most frequently used drug. In general the results of the present study are in agreement with those of previous studies, underlining the need to consider a diagnosis of tics in young children and highlighting the importance of identification and appropriate treatment of comorbidities.

    To evaluate the clinical value of T-staging system for hilar cholangiocarcinoma which was adopted in memorial Sloan-Kettering cancer center of New York. The image data of these 47 patients were analyzed retrospectively from December 1997 to December 2002 whose data were according with our demand, and they were staged into three-stage according to the criteria of the T-staging system. The difference of respectability, ratio of tumor-free resection margin and actuarial survival rate were analyzed for different T-staging. And the coincident ratio of three different kinds of imaging methods was also analyzed. Twenty patients had T(1) tumors, twenty three had T(2) tumors and four had T(3) tumors. The resectability of the three stage was 60%, 39% and 0% respectively, and the difference was significant (P = 0.013). The likelihood of achieving tumor-free margin decreased progressively with increasing T stage (P = 0.018). The cumulative 1-year survival rates of T(1), T(2) and T(3) patients were 60%, 39% and 0% respectively, and the cumulative 3-year survival rate was 35%, 9% and 0% respectively, the survival of different stage patients differed markedly (P = 0.0103). The coincident ratio of combined using MRCP and color Doppler-ultrasonography was higher than that of combined using MRCP and B-ultrasonography or combined using CT/SCT and color Doppler-ultrasonography (P = 0.007). The T-staging system has a better value for preoperative assessment, and can be used to judge resectability and survival of hilar cholangiocarcinoma. It will be helpful to use MRCP and color Doppler-Ultrasonography combined to verdict the coverage of the tumor and the T-staging preoperatively.

    The introduction of flexible bronchoscope has revolutionized the field of pulmonary medicine and is a standard instrument used for diagnostic purpose. A retrospective analysis of the clinico-radiological profile, indication, biopsy procedure and complications, for patients undergoing bronchoscopy at one of the respiratory unit at a tertiary care center in India. Retrospective analysis of 712 bronchoscopies was done in regard to demographic profile, clinical and radiological presentation and diagnostic indication. The results were analyzed on basis of bronchoscopy inspection and histopathological specimen obtained from transbronchial (TBLB), endobronchial biopsy (EBLB) and cytology specimen by transbronchial needle aspiration (TBNA). Furthermore, diagnostic yield of each biopsy procedure and their combination was evaluated. Of 712 patients undergoing bronchoscopy, the pathological diagnosis was achieved in 384 (53.93%). Of 384 diagnosed cases, the clinic-radio-pathological diagnosis of pulmonary tuberculosis in 88 (22.19%), interstitial lung disease (ILDs) in 226 (58.85%), and lung cancer in 70 (18.22%) cases. Of 116 sputum smear negative tuberculosis patients, 88 (75.86%) were diagnosed to be pulmonary tuberculosis; the contribution of BAL being 71.59%. Of 226 ILDs, sarcoidosis was most common 148/226 (65.48%). Among 70 lung cancer diagnosed cases, squamous cell carcinoma was most common (54.28%). The results from current study reemphasizes on the diagnostic utility as well as safety of the bronchoscopy procedure. Copyright © 2015 Tuberculosis Association of India. Published by Elsevier B.V.

    The present retrospective study evaluated the recurrence patterns after aggressive surgical removal of intracranial glioblastomas in 43 consecutive adult patients. The resection rate of the enhanced lesion on magnetic resonance imaging was 100% and 95-99% in 22 and 21 cases, respectively. All patients received postoperative fractionated radiotherapy (60 Gy in 30 fractions) with additional chemotherapy (25 cases) or vaccine therapy (18 cases). During follow-up (median 17 months), tumor recurrence was identified in 33 patients, most frequently regional within the wall of the resection cavity (20 cases). No clinical factor differed significantly between the groups of patients with regional or marginal tumor progression (N=22) and patients with distant or multiple recurrences (N=8). Progression-free survival did not differ significantly between these two groups (p=0.27). However, overall survival was significantly longer (p=0.04) in patients with regional or marginal tumor progression, and constituted 90% and 54% at 1 and 2 years after surgery, respectively, compared to 75% and 0% in patients with distant or multiple recurrences. Aggressive surgical resection and adjuvant management of intracranial glioblastoma may change its recurrence pattern. Tumor progression appears in the wall of the resection cavity or within 2 cm from its margin in approximately half of patients. (author)

    Objective: To explore the optimal parameters of high pressure injector in performing interventional angiography and therapy of different parts of body in order to improve the image quality. Methods: During the period from July 2009 to September 2010 interventional angiography or therapy of different parts of body with the help of high pressure injector was performed in 692 patients, including 538 males and 154 females with a mean age of (53.6±2.5) years. The clinical data were retrospectively analyzed. The angiographic regions included vessels (n=341), cerebral vessels (n=71), thoracic larger vessels (n=19) and the vessels of the arms and legs (n=203). The technical parameters and the image qualities were evaluated and analyzed. Results: Based on the contrast filling degree, the presence or absence of contrast reflux, the imaging resolution and the satisfactory degree in meeting the diagnostic requirements, the angiographic images were evaluated. The image quality was up to standard in 615 cases (88.7%). Unsatisfactory contrast filling with no contrast reflux was seen in 62 cases (9.0%), and poor vascular opacification with contrast reflux was found in 9 cases (1.3%). Vagueness of the images caused by the body movement during exposure was seen in 6 cases (0.8%). No accidental events occurred in all procedures. Conclusion: The use of appropriate catheter, equipment and reasonable injecting parameters, which can match the characteristics of the target lesions, is the key to provide physicians with reliable angiography images.

    To examine the barriers to and facilitators of practice facilitation experienced by participants in the Improving Delivery of Cardiovascular Care (IDOCC) project. Case studies of practice facilitators' narrative reports. Eastern Ontario. Primary care practices that participated in the IDOCC project. Cases were identified by calculating sum scores in order to determine practices' performance relative to their peers. Two case exemplars were selected that scored within ± 1 SD of the total mean score, and a qualitative analysis of practice facilitators' narrative reports was conducted using a 5-factor implementation framework to identify barriers and facilitators. Narratives were divided into 3 phases: planning, implementation, and sustainability. Barriers and facilitators fluctuated over the intervention's 3 phases. Site A reported more barriers (n = 47) than facilitators (n = 38), while site B reported a roughly equal number of barriers (n = 144) and facilitators (n = 136). In both sites, the most common barriers involved organizational and provider factors and the most common facilitators were associated with innovation and structural factors. Both practices encountered various barriers and facilitators throughout the IDOCC's 3 phases. The case studies reveal the complex interactions of these factors over time, and provide insight into the implementation of practice facilitation programs.

    We report on embolization in 36 cases of postpartum hemorrhage (PPH). The 36 patients with severe PPH, including one patient who had undergone an emergency hysterectomy, were transferred to the regional interventional vascular radiology unit in a mean time of 6 hours 12 min. Bilateral occlusion of the anterior trunk of the hypogastric arteries was carried out using gelatin sponge. Immediate success was achieved in all cases. In 3 cases, however, a second embolization was necessary before day 2. In 17%, complementary nonvascular surgery was performed. Complications included one puncture site false aneurysm treated by compression, two cases of regressive lower limb paraesthesia, one femoral vein thrombosis, and nonsignificant puncture site hematomas (19.5%). Long-term follow-up was conducted in 23 patients: 91% resumed regular menstrual cycles, 8.7% dysmenorrhea. New pregnancy occurred in 13% (two full-term pregnancies and one voluntary termination). Immediate efficacy, low morbidity and preservation of fertility make embolization the technique of choice for severe PPH

    The aim of this study is to demonstrate the clinical applicability and efficacy of an allograft for maxillary sinus augmentations in patients requiring placement of dental implants. Sixty consecutive patients underwent a total of 90 sinus augmentations. Twenty-nine were women and 31 men, with a mean age of 54 years. Twenty-six patients received a bilateral procedure and 34 unilateral. All cases were treated with the lateral wall technique. Allograft consisted of demineralized freeze-dried blocks in 6 cases, particulate in 82 cases, and a combination of both in 2 cases. In 30 patients, it was combined with platelet-rich plasma. A total of 84 implants were inserted. Bone samples of grafted areas were obtained in two patients for histological examination. Seventy-three implants were clinically successful at the reentry time. Eleven implants in seven patients were removed between 15 days and 6 months after their placement. Seven of these implants were replaced and received prostheses as well, for an overall postloading success rate of 95.2%. Follow-up for all patients after final restoration was between 12 and 96 months. Specimen's histological evaluation revealed bone formation and evidence of inflammatory infiltrate. Based on the findings of this study, it can be suggested that the use of the demineralized freeze-dried bone allograft from the Banco de Huesos y Tejidos Fundación Cosme y Damian for sinus augmentation is effective and constitutes a feasible therapeutic alternative for implant placement.

    In acute leukaemia (AL), the occurrence of pulmonary mucormycosis (PM), the incidence of which is increasing, as a result of chemotherapy induced marrow aplasia, remains a life threatening complication. Analysis of clinical, biological and thoracic CT characteristics of patients with PM developing during the treatment of AL between 2000 and 2015. Day 0 (D0) was defined as the day with first CT evidence of PM. Among 1193 patients, 25 cases of PM were recorded during 2099 episodes of bone marrow aplasia. At time of diagnosis of PM, 24/25 patients had been neutropenic for a median of 12 days. None of the patients had diabetes mellitus. On initial CT (D0), the lesion was solitary in 20/25 cases and a reversed halo sign (RHS) was observed in 23/25 cases. From D1 to D7, D8 to D15 and after D15, RHS was seen in 100 %, 75 % and 27 % of cases, respectively. A tissue biopsy was positive in 17/18 cases. The detection of circulating Mucorales DNA in serum was positive in 23/24 patients and in 97/188 serum specimens between D-9 and D9. Bronchoalveolar lavage contributed to diagnosis in only 3/21 cases. The antifungal treatment was mainly based on liposomal amphotericin B combined with, or followed by, posaconazole. A pulmonary surgical resection was performed in 9/25 cases. At 3 months, 76 % of patients were alive and median overall survival was 14 months. In AL, early use of CT could improve the prognosis of PM. The presence of a RHS on CT suggests PM and is an indication for prompt antifungal treatment. Copyright © 2018 SPLF.

    Diagnostic records from 338 canine oral melanomas in 338 dogs received at the Veterinary Medical Diagnostic Laboratory (1992-1999) were reviewed. Of these tumors, 122 plus an additional 7 metastatic melanomas of unknown origin were selected for clinical follow-up, histologic review, and immunohistochemistry. Chow Chow, Golden Retriever, and Pekingese/Poodle mix breeds were overrepresented, whereas Boxer and German Shepherd breeds were underrepresented. There was no gender predisposition and the average age at presentation was 11.4 years. Forty-nine dogs were euthanized due to recurrence or metastasis. The average postsurgical survival time was 173 days. The gingiva and the labial mucosa were the most common sites. Most tumors were composed of either polygonal cells (27 cases, 20.9%), spindle cells (44 cases, 34.1%), or a mixture of the two (polygonal and spindle) (54 cases, 41.9%). Clear cell (3 cases, 2.3%) and adenoid/papillary (1 case, 0.8%) patterns were uncommon. The metastases of 6/6 oral melanomas had morphologic and immunohistochemical features similar to those of the primary tumors. Immunohistochemically, Melan A was detected in 113/122 oral (92.6%) and 5/7 (71.9%) metastatic melanomas. Only 4/163 nonmelanocytic tumors were focally and weakly positive for Melan A. Antibodies against vimentin, S100 protein, and neuron-specific enolase stained 129 (100%), 98 (76%), and 115 (89.1%) of 129 melanomas, respectively. Antibodies against other melanocytic-associated antigens (tyrosinase, glycoprotein 100) did not yield adequate staining. We conclude that Melan A is a specific and sensitive marker for canine melanomas.

    Case histories are described in which measurable improvements in the cabin noise environments of the Bell 214B, 206B, and 222 were realized. These case histories trace the noise control efforts followed in each vehicle. Among the design approaches considered, the addition of a fluid pulsation damper in a hydraulic system and the installation of elastomeric engine mounts are highlighted. It is concluded that substantial weight savings result when the major interior noise sources are controlled by design, both in altering the noise producing mechanism and interrupting the sound transmission paths.

    Full Text Available Introducción: la esofagitis necrosante aguda es una entidad rara. Se reconoce por el aspecto negro difuso del esófago a la endoscopia. Su incidencia e patogénesis se desconoce. Pacientes y métodos: se analizaron retrospectivamente 11 pacientes con esofagitis necrosante aguda desde el punto de vista de los datos clínicos, de laboratorio y endoscopicos en 2 años. Resultados: se analizaron las endoscopias realizadas a 3.976 pacientes, observándose esofagitis necrosante aguda en 11 pacientes. El estado nutricional era malo en 6 pacientes. La resolución completa de la esofagitis se observó en cuatro pacientes. Durante el seguimiento se observó una estenosis en un paciente y un nuevo episodio de esofagitis necrosante aguda en otro paciente. Siete pacientes fallecieron, pero esta elevada mortalidad parece deberse a las enfermedades de base y no es atribuible a las lesiones de la esofagitis necrosante. Conclusiones: la incidencia de esofagitis necrosante aguda en nuestra serie fue 0,28%. La esofagitis necrosante aguda tiene una elevada mortalidad.Background: acute esophageal necrosis has been considered a rare event. It is defined as the presence of diffuse dark pigmentation of the esophagus on upper endoscopy. Its incidence has not yet been established. The pathogenesis remains unknown. Patients and methods: a retrospective analysis of clinical, laboratory, endoscopic, and histological data, and of the clinical course of 11 patients with acute necrotizing esophagitis was carried out over a 2-year period. Results: among 3,976 patients who underwent upper endoscopy, 11 (0.28% with acute esophageal necrosis were identified. Nutritional status was poor for 6 patients. Complete resolution of acute esophageal necrosis without further recurrence was observed in 4. One stricture appeared during follow-up and other patient developed new-onset acute esophageal necrosis. Seven patients died, but no death was directly related to acute esophageal necrosis

    Purpose: This retrospective study was designed to evaluate the role of adjuvant radiotherapy for surgically treated endometrial carcinoma. Patients and methods: From 1980 through 1988, 541 patients were treated with either intravaginal cuff irradiation with a high-dose-rate (HDR) Iridium-192 remote afterloading technique (n=294) or with combined HDR-brachytherapy and additional external pelvic irradiation to 54 Gy (n=247) after surgery for endometrical cancer. Afterloading irradiation was administered in 4 fractions 4 to 6 weeks after surgery. A dose of 30 Gy was delivered at a depth of 0,5 cm from the vaginal mucosa. Results: Patients with HDR-brachytherapy alone showed a 5-year survival of 94.3% for Stage I and 73.6% for Stage II (p=0.0007). Patients who received both brachytherapy and additional pelvic irradiation had a 5-year survival of 94.1% for Stage I, 81.1% for Stage II, 70.4% for Stage III and 46.9% for Stage IV (p=0.0001). The main predictors for survival in a multivariate analysis were stage and grading. Patients with combined readiotherapy had a local recurrence rate of 3.2%, whereas patients with brachytherapy alone who were better selected and had more favorable prognostic factors showed a recurrence rate of 2%. Low-risk patients (Stage I, Grade 1, low infiltration) in the HDR-brachytherapy group had 6 relapses, mainly caused by insufficient treatment on the basis of papillary histology. High-risk patients with poorly differential tumors, which infiltrate more than half the myometrial wall might benefit from additional external radiotherapy in terms of reduction of local recurrence and better survival. Five-year actuarial survival rate was 93.6% after combined radiotherapy vs 86.7% after brachytherapy alone. Complications were graded according to the RTOG scoring system. Severe late complications were fistulas of bladder and/or bowel, which occurred in 2.8% in the combined radiotherapy group, and 0.7% in the HDR brachytherapy group. (orig.) [de

    Recent studies have reported an increase in intensity and frequency of hydrological extreme events in many regions of the Amazon basin over last decades, these events such as seasonal floods and droughts have originated a significant impact in human and natural systems. Recently, methodologies such as climatic reanalysis are being developed in order to create a coherent register of climatic systems, thus taking this notion, this research efforts to produce a methodology called Hydrological Retrospective (HR), that essentially simulate large rainfall datasets over hydrological models in order to develop a record over past hydrology, enabling the analysis of past floods and droughts. We developed our methodology on the Amazon basin, thus we used eight large precipitation datasets (more than 30 years) through a large scale hydrological and hydrodynamic model (MGB-IPH), after that HR products were validated against several in situ discharge gauges dispersed throughout Amazon basin, given focus in maximum and minimum events. For better HR results according performance metrics, we performed a forecast skill of HR to detect floods and droughts considering in-situ observations. Furthermore, statistical temporal series trend was performed for intensity of seasonal floods and drought in the whole Amazon basin. Results indicate that better HR represented well most past extreme events registered by in-situ observed data and also showed coherent with many events cited by literature, thus we consider viable to use some large precipitation datasets as climatic reanalysis mainly based on land surface component and datasets based in merged products for represent past regional hydrology and seasonal hydrological extreme events. On the other hand, an increase trend of intensity was realized for maximum annual discharges (related to floods) in north-western regions and for minimum annual discharges (related to drought) in central-south regions of the Amazon basin, these features were

    Women in Scotland with uncomplicated pregnancies are encouraged by professional bodies and national guidelines to access community based models of midwife-led care for their labour and birth. The evidence base for these guidelines relates to comparisons of predominantly urban birth settings in England. There appears to be little evidence available about the quality of the care during the antenatal, birth and post birth periods available for women within the Scottish Community Maternity Unit (CMU) model. The research aim was to explore the safety and effectiveness of the maternity services provided at two rural Community Maternity Units in Scotland, both 40 miles by main road access from a tertiary obstetric unit. Following appropriate NHS and University ethical approval, an anonymous retrospective review of consecutive maternity records for all women who accessed care at the CMUs over a 12 month period (June 2011 to May 2012) was undertaken in 2013 -14. Data was extracted using variables chosen to provide a description of the socio-demographics of the cohort and the process and outcomes of the care provided. Data were analysed using descriptive statistics. Regarding effectiveness, the correct care pathway was allocated to 97.5% of women, early access to antenatal care achieved by 95.7% of women, 94.8% of women at one CMU received continuity of carer and 78.6% of those clinically eligible accessed care in labour. 11.9% were appropriately transferred to obstetrician-led care antenatally and 16.9% were transferred in labour. All women received one-to one care in labour and 67.1% of babies born at the CMUs were breastfed at birth.

    Background: Patent ductus arteriosus (PDA) is one of the most common congenital heart diseases and began to get treated by transcatheter occlusion since 1997 in China. Since then, several devices have been invented for occluding PDA. This study aimed to evaluate the technical feasibility, safety, and efficacy of transcatheter occlusion of PDA with different devices. Methods: One thousand five hundred and twenty-six patients (537 boys, 989 girls) with PDA from January 1997 to September 2014 underwent descending aortogram and transcatheter occlusion procedure. We retrospectively analyzed data of these patients, including gender, age, weight, size and morphology of PDA, and devices used in transcatheter occlusion, outcomes, and postoperational complications. Results: Median age and median weight were 4.0 years (range: 0.3–52.0 years old) and 15.3 kg (range: 4.5–91.0 kg), respectively. Mean ductal diameter, aortic ductal diameter, ductal length, and pulmonary artery pressure were 3.50 ± 2.15 mm, 10.08 ± 2.46 mm, 7.49 ± 3.02 mm, and 30.21 ± 17.28 mmHg, respectively. Morphology of PDA assessed by descending aortogram was of type A in 1428 patients, type B in 6 patients, type C in 79 patients, type D in 4 patients, and type E in 9 patients according to the classification of Krichenko. Of all the 1526 patients, 1497 patients underwent transcatheter PDA closure, among which 1492 were successful. Devices used were Amplatzer duct occluder I (ADO I, 1280, 85.8%), Cook detachable coils (116, 7.8%), ADO II (ADO II, 68, 4.6%), muscular VSD occluder (12, 0.8%), and Amplatzer vascular plug (16, 1.0%). Conclusions: Excellent occlusion rates with low complication rates were achieved with all devices regardless of PDA types. With transcatheter occlusion technique and devices developing, more patients with PDA can be treated with transcatheter closure both safely and efficiently. PMID:26315073

    A wide variety of intoxications and abnormal metabolic conditions can lead to reactive seizures in dogs. Patient records of dogs suffering from seizure disorders (n=877) were reviewed, and 96 cases were associated with an underlying metabolic or toxic aetiology. These included intoxications by various agents, hypoglycaemia, electrolyte disorders, hepatic encephalopathy, hypothyroidism, uraemic encephalopathy, hypoxia and hyperglycaemia. The incidence of the underlying diseases was determined. The most common causes of reactive seizures were intoxications (39%, 37 dogs) and hypoglycaemia (32%, 31 dogs). Hypocalcaemia was the most frequent electrolyte disorder causing reactive seizures (5%) and all five of these dogs had ionised calcium concentrations ≤0.69 mmol/L. Eleven per cent of dogs with seizures had metabolic or toxic disorders and this relatively high frequency emphasises the importance of a careful clinical work-up of cases presented with seizures in order to reach a correct diagnosis and select appropriate treatment options.

    Ambystoma mexicanum kept as pets are affected by a variety of diseases. However, no reports regarding the incidence of specific diseases are available. This study aimed to identify the diseases that occur frequently in this species by surveying the incidence of conditions in pet A. mexicanum specimens brought to a veterinary hospital. The sample comprised 97 pet A. mexicanum individuals brought to the authors' hospital during the 82-month period, i.e., from January 2008 to October 2014. In total, 116 diseases were identified. The most common disease was hydrocoelom (32 cases; 27.5% of all cases). Elucidating the pathogenesis of hydrocoelom, which has a high prevalence rate, is vital to maintaining the long-term health of A. mexicanum pets.

    1995-01-01

    The usefulness of computed tomography (CT) in thoracic radiology is now well appreciated, and the number of chest CTs has greatly increased. There are, however, many chest CT cases that are completely or almost completely normal. Indications for chest CT should be re-evaluated considering the cost and radiation exposure associated with the examination. Reviewing the reports of 4930 chest CT examinations performed in three hospitals during the period of two years, the author found 620 (12.6%) negative CT examinations. In 312 of the 620, the CT was requested because of 'abnormal shadow' on chest radiograph. When the same chest radiographs were re-evaluated by two radiologists, no abnormality was noted in 257 cases (82.4%). CT examinations were considered justified in only 55 cases (17.6%). There was a significant difference in the frequency of normal chest CT examinations between the university hospital and two other hospitals. The causes of false positive interpretation of chest radiographs were analyzed, and it was felt that fundamental knowledge necessary to interpret chest radiographs was lacking. The importance of close cooperation between clinicians and radiologists should be emphasized. (author)

    Background: Computed tomography (CT) for evaluation of sacroiliitis has a higher diagnostic accuracy than radiography. There is a high degree of interobserver variation in evaluating sacroiliitis on radiographs. Purpose: To evaluate interobserver variation in CT of the sacroiliac joints for evaluation of sacroiliitis in a large number of patients. Material and Methods: 1383 CT examinations of the sacroiliac joints were reviewed by two observers. The outcomes as originally reported and the findings from the reviews were classified as no sacroiliitis, equivocal, unilateral sacroiliitis, or bilateral sacroiliitis. The unweighted kappa statistic was used for assessment of observer agreement. Results: The interobserver agreement between the two reviewers was good (0.6724), with excellent agreement on cases of bilateral sacroiliitis and moderate agreement on cases of unilateral sacroiliitis. Excellent agreement was also reached in normal cases. Compared to the original reports, there were moderate interobserver agreements between both reviewers' findings and the original reports 0.4651 and 0.4481, respectively). Conclusion: The interobserver variation for the diagnosis of sacroiliitis on CT between two reviewers in a study setting showed good agreement, with moderate agreement between each of the observers and the original clinical reports. CT is a reliable method for evaluating the sacroiliac joints for changes of sacroiliitis

    1989-04-01

    From January 1979 through March 1988, our regional poison center, located many hundreds of miles from the nearest coastal salt water, documented 23 cases of envenomation by "Lionfish" (members of genus Pterois). All cases involved specimens which were maintained in the homes of amateur aquarists. A study of patient epidemiology showed the following: patient's sex 91.3% male, 8.7% female; patients ages ranged from 17 to 50 years with an average age for males of 29.8 years and 35 years for females; the site of the envenomation accident was always in the home; the only part of the body envenomated was the hand or finger; and all of the patients were symptomatic. Symptoms noted included sharp pain, swelling, redness, bleeding, nausea, numbness, joint pain, anxiety, headache, disorientation, and dizziness. One patient had a complication of cellulitis. Treatment provided included immersion of the effected area in hot water at 40 C for 60 to 90 min, analgesics, tetanus toxoid, and antibiotics. There were no deaths noted and treatment proved effective in all cases. This paper also discusses the natural history, clinical effects, and current treatment for envenomations from these beautiful but dangerous venomous fish, which can cause poisoning exposures that are likely to be encountered by poison centers anywhere in the world.

    Our aim was to describe the epidemiologic, clinical, and laboratory characteristics of acute parvovirus B19 infection in adults. This study describes all cases of acute parvovirus B19 infection in patients older than 18 years of age who were treated at Hospital Universitario La Paz in Madrid, Spain, in 2012. Forty-nine adults were treated for acute parvovirus B19 infection. Most were young women who were infected in the spring or early summer. In over half the cases skin lesions were key diagnostic signs.We saw the full range of types of rash of purplish exanthems that were fairly generalized; vasculitis was relatively common (in >18%). Mild or moderate abnormalities in blood counts and indicators of liver dysfunction resolved spontaneously in all but 2 immunocompromised patients, who developed chronic anemia. This is the largest case series of acute parvovirus B19 infection published to date. This infection should be suspected on observing signs of purplish skin rashes, no matter the location or pattern of distribution, or vasculitis, especially if accompanied by fever and joint pain in young women in the spring. Measures to avoid infection should be recommended to individuals at risk. Copyright © 2014 Elsevier España, S.L.U. and AEDV. All rights reserved.

    Case-control study designs are commonly used. However, many published case-control studies are not true case-controls and are in fact mislabeled. The purpose of this study was to identify all case-control studies published in the top three plastic surgery journals over the past 10 years, assess which were truly case-control studies, clarify the actual design of the articles, and address common misconceptions. MEDLINE, Embase, and Web of Science databases were searched for case-control studies in the three highest-impact factor plastic surgery journals (2005 to 2015). Two independent reviewers screened the resulting titles, abstracts, and methods, if applicable, to identify articles labeled as case-control studies. These articles were appraised and classified as true case-control studies or non-case-control studies. The authors found 28 articles labeled as case-control studies. However, only six of these articles (21 percent) were truly case-control designs. Of the 22 incorrectly labeled studies, one (5 percent) was a randomized controlled trial, three (14 percent) were nonrandomized trials, two (9 percent) were prospective comparative cohort designs, 14 (64 percent) were retrospective comparative cohort designs, and two (9 percent) were cross-sectional designs. The mislabeling was worse in recent years, despite increases in evidence-based medicine awareness. The majority of published case-control studies are not in fact case-control studies. This misunderstanding is worsening with time. Most of these studies are actually comparative cohort designs. However, some studies are truly clinical trials and thus a higher level of evidence than originally proposed.

  16. Radiotherapy of Painful Vertebral Hemangiomas: The Single Center Retrospective Analysis of 137 Cases

    Miszczyk, Leszek; Tukiendorf, Andrzej

    2012-01-01

    Purpose: An evaluation of dose–response relationship and an attempt to define predictive factors. Methods and Materials: A total of 137 cases of painful vertebral hemangioma irradiations (101 patients). Fraction dose (fd) varied from 2 to 15 Gy (123 fractionated and 14 radiosurgical treatments), and total dose (TD) from 8 to 30 Gy (111 cases irradiated with fd of 2 GY to TD of 24 Gy). We evaluated pain relief, changes in analgesic requirements, and reossification. Results: Means of pain relief 1, 6, 12, and 18 months after radiotherapy (defined as a decrease of primary pain level expressed in percent) were 60.5%, 65.4%, 68.3%, and 78.4%, respectively. Proportion of patients with no need for analgesics and patients using tramadol were 39%, 40%, 44%, 57%, and 20%, 17%, 22%, and 11% in these times. The proportion of patients experiencing complete/partial pain relief changed from 36/48% 1 month, to 64/22% 1.5 years after radiotherapy. No impact of radiotherapy on reossification was found. The positive impact of fd and TD increase for analgesics uptake reduction and pain relief was found. An increase of the fd by 1 Gy results in 27% chance of analgesics uptake reduction and 3.8% reduction of pain, whereas 14% analgesics uptake reduction and 2.2% of pain reduction in case of the TD. The predictive factors improving results were found: female gender, older age, better performance states (the chance of the lower analgesic treatment decreases over 2.5 times in comparison to the higher Zubrod degree), bigger Hb concentration, shorter symptoms duration and lower analgesics uptake before radiotherapy. Conclusions: The obtained data support the efficacy of radiotherapy in improving pain secondary to vertebral hemangioma, with the degree of pain amelioration being related to increasing fd and TD. The positive predictive factors were defined: female gender, older age, better performance status, increased Hb concentration, shorter symptoms duration, and lower analgesics uptake

    This retrospective project summarizes the types of neoplasms identified in Virginia opossums ( Didelphis virginiana) presented to the University of Tennessee, College of Veterinary Medicine (UTCVM) postmortem service in 1989-2014 and serves as a review of the literature. Of the 85 Virginia opossums identified from the UTCVM case database, there were 17 diagnoses of neoplasia from 12 cases (14%). These cases included 8 females, 2 males, and 2 neutered males. All opossums with known ages (11 of 12) were >2 y old. Pulmonary tumors, specifically minimally invasive or lepidic-predominant adenocarcinomas, were the most common diagnosis and accounted for 53% (9 of 17) of the neoplasms. Additional tumors included acute myeloid leukemia with eosinophil maturation, hepatic hemangiosarcoma, sarcoma (unknown origin), squamous cell carcinoma, disseminated mast cell tumor, trichoblastoma, thyroid adenoma, and an osteoma. These findings serve as a reference for the types of spontaneous neoplasms in Virginia opossums; based on these findings, neoplasia should be considered as a differential in mature captive Virginia opossums.

    In order to specify the indications for conservative surgery and preoperative therapeutic approaches of soft tissues sarcomas (STS), we looked for the clinico-pathological parameters associated with the failure to obtain a complete removal (CRm) of the tumor. We retrospectively analyzed a series of 592 cases of primary non-metastatic STS. Surgery was performed in 495 cases as a primary treatment and in 88 cases after chemo- or radiotherapy. Nine patients were treated by chemotherapy-radiotherapy. In a univariate analysis, 20 parameters were tested for their association with CRm. A multivariate analysis was then used to define the independent parameters linked to the achievement of a CRm. In the univariate analysis, 15 parameters were found to be linked to the achievement of a CRm. Three of them proved to be independent in the multivariate analysis: T in the TNM classification, tumor location, and tumor necrosis. By the combination of these risk factors, four groups of patients were defined, with respective rates of CRm of 97% (no factor), 95% (one factor), 70% (two factors), and 48% (three factors). The achievement of a CRm after surgery of STS depends not only on the accessibility of the lesion, but also on tumor aggressiveness, a reflection of which is necrosis. The detection of necrosis by imaging procedures may thus help predicting the resectability of tumors and defining the indications for neoadjuvant therapies, likely to broaden the use of conservative surgery.

    2007-01-01

    The New Zealand Human Assisted Reproductive Technology (HART) Act became law in 2004. In this article, we provide a retrospective analysis of New Zealand case law from September 1990 to March 2004, leading up to the creation of the HART Act. We examine the new understandings of parenting (developed through the routine use of ART in New Zealand) which the case law attempted to test. We examine these concepts against the previous understandings of family enshrined in the pre-existing legislation, which formed the basis for judicial rulings in the various cases to which we refer. In conclusion, we provide a brief summary of the 2004 HART legislation and draw comparisons between the old and new legislative and bureaucratic frameworks that define and support New Zealand family structure. We suggest that a change in cultural backdrop is occurring from the traditional western ideology of the nuclear family towards the traditional Maori concept of family formation, which includes a well-accepted traditional practice of guardianship and a more open and extended family structure. This 'new' structure reflects the contemporary lived experience of family kinship in western societies as individualized and open to choice.

    The aim of this study was to evaluate the results of the surgical treatment of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in a large cohort. A retrospective cohort multicenter study was designed. Patients were enrolled if they were diagnosed with BRONJ and received operative treatment. Data on demographic, health status, perioperative, and surgical factors were collected retrospectively. The primary outcome variable was a change in BRONJ staging (improvement, worsening, or no change). Interventions were grouped by local debridement and resective surgery. Data were collected for other variables as cofactors. Univariate analysis and logistic regressions were then performed. Of the 347 BRONJ-affected subjects, 59% showed improvement, 30% showed no change, and 11% showed worsening. Improvement was observed in 49% of cases treated with local debridement and 68% of cases treated with resective surgery. Multivariate analysis indicated that maxillary location, resective surgery, and no additional corticosteroid treatment were associated with a positive outcome. Surgical treatment of BRONJ appeared to be more effective when resective procedures were performed. Nonetheless, other factors, such as the absence of symptoms and the types of drug administration, should be taken into account before clinical decisions are made.

    Directory of Open Access Journals (Sweden)

    Kharbanda Y

    1991-04-01

    Full Text Available Hundred and ten consecutive cases in acute and various stages of chronicity were studied. Incidence regarding age, sex, bone affected and complications was established. The optimum way to manage osteomyelitis in different stages was sought. It was found that in acute stage early decompression of bone leads to resolution of disease. Hip involvement leads to necrosis of capital epiphysis and should be treated on an emergency basis. In the sub-acute stage it is necessary to protect the weakened bone. In chronic stage, we suggest sequestrectomy only after adequate involucrum has formed properly. Antibiotics in acute stage should be instituted as early as possible and should be continued for three weeks after the fever subsides. Antibiotics in sub-acute and chronic stage are given only in cases of reactivation of infection and around the time of surgery. Surgery, when required should be performed without too much soft tissue damage especially the covering periosteum. But repeated surgery should be avoided as they lead to cicatrization of muscles and further sequestration of bone.

    This study examined the incidence and risk factors for gastrointestinal (GI) bleeding after spontaneous intracerebral hemorrhage (ICH). The available medical records of patients with ICH admitted from June 2008 to December 2009 for any episode of GI bleeding, possible precipitating factors and administration of ulcer prophylaxis were reviewed. The prevalence of GI bleeding was 26.7%, including 3 cases of severe GI bleeding (0.35%). Patients with GI bleeding had significantly longer hospital stay and higher in-hospital mortality compared with patients without GI bleeding. Multivariate logistic regression analyses showed that age, Glasgow Coma Scale scores, sepsis and ICH volume were independent predictors of GI bleeding. About 63.4% of patients with ICH received stress ulcer prophylaxis. GI bleeding occurred frequently after ICH, but severe events were rare. Age, Glasgow Coma Scale score, sepsis and ICH volume were independent predictors of GI bleeding occurring after ICH.

    Full Text Available Respiratory amyloidosis is a rare disease which refers to localized aberrant extracellular protein deposits within the airways. Tracheobronchial amyloidosis (TBA refers to the deposition of localized amyloid deposits within the upper airways. Treatments have historically focused on bronchoscopic techniques including debridement, laser ablation, balloon dilation, and stent placement. We present the outcomes after rigid bronchoscopy to remove the amyloid protein causing the airway obstruction in 6 cases of tracheobronchial amyloidosis. This is the first report of primary diffuse tracheobronchial amyloidosis in our department; clinical features, in addition to therapy in the treatment of TBA, are reviewed. This paper shows that, in patients with TBA causing airway obstruction, excellent results can be obtained with rigid bronchoscopy and stenting of the obstructing lesion.

    Well's syndrome, or eosinophilic cellulitis, is rare in childhood, with fewer than 40 pediatric cases being reported since 1979. The physiopathology is unknown. In February 2012, members of the research group of the Department of Pediatric Dermatology Society submitted their case of Wells' syndrome in children aged 0-15 years. Details of clinical, biological and histological features and of therapeutic strategies were collected by physicians using a standardized questionnaire. Pictures were reviewed by the authors. Eleven patients were included (average age: 6 years), with a strong prevalence of atopy (63%). Two types of clinical manifestation were noted: single or multiple cellulitis associated or not with vesiculobullous lesions and fixed urticaria. Eighty-two percent of patients had pruritus and 73% had eosinophilia. For all patients, histological examination of skin biopsies showed an eosinophilic infiltrate extending in the dermis with associated Sweet-like neutrophilic infiltrate being seen in 2 patients. The course of the disease was protracted (mean duration: 8 months) with flare-ups. Treatment varied depending on the doctors (topical or systemic steroids, tacrolimus and dapsone). Our study confirms some of the data in the literature concerning the clinical, histological features and course of Well's syndrome in children. The key information is the high prevalence of atopic children hitherto unreported. In a setting of insect bites, vaccination, infection or traumatism, this unusual background could explain the onset of inflammatory reaction with eosinophils. Oral or topical steroids appear to be the first-line treatment in children when necessary. Well's syndrome in children is rare and characterized by its polymorphism. We report for the first time in a series of patients a high prevalence of atopy, which raises new perspectives in understanding these rare diseases. We propose topical steroids as first-line therapy in children with superficial lesions

Hospital controls may be inadequate and random controls drawn from the base population may be unavailable. The aim was to assess the use of hospital visitors as controls in a case-control study on the association of organochlorinated compounds and other risk factors for breast cancer conducted in the main hospital of the "Instituto Nacional de Câncer" -- INCA (National Cancer Institute in Rio de Janeiro (Brazil. METHODS: The study included 177 incident cases and 377 controls recruited among female visitors. Three different models of control group composition were compared: Model 1, with all selected visitors; Model 2, excluding women visiting relatives with breast cancer; and Model 3, excluding all women visiting relatives with any type of cancer. Odds ratios (OR and 95% confidence intervals were calculated to test the associations. RESULTS: Age-adjusted OR for breast cancer associated with risk factors other than family history of cancer, except smoking and breast size, were similar in the three models. Regarding family history of all cancers, except for breast cancer, there was a decreased risk in Models 1 and 2, while in Model 3 there was an increased risk, but not statistically significant. Family history of breast cancer was a risk factor in Models 2 and 3, but no association was found in Model 1. In multivariate analysis a significant risk of breast cancer was found when there was a family history of breast cancer in Models 2 and 3 but not in Model 1. CONCLUSIONS: These results indicate that while investigating risk factors unrelated to family history of cancer, the use of hospital visitors as controls may be a valid and feasible alternative.

In the cases that deviated from the standard treatment and that became impossible to use rifampicin, it should be careful to emergence of isoniazid resistance. 3. The current status of the recurrence tuberculosis cases in Tokyo: Michiko NAGAMINE (Specific Disease Control Section, Tokyo Metropolitan Government Bureau of Social Welfare and Public Health). As for the background of the patient whose disease has relapsed, unstable elements are observed. After any symptom, more patients are diagnosed as a relapse case rather than finding by a medical check up. And more than half are related to homeless or life without fixed address. Their status of insurance is the livelihood protection, no insurance or the national health insurance. By RFLP analysis in Shinjuku city, some clusters have recurrent cases, one of clusters has both a relapse and exogenous reinfection. This is able to elucidate an infectious state. Like this, the analysis of each cluster can help effective countermeasures. 4. Recurrence of tuberculosis in the City of Yokohama between 2004 and 2008: Michihiko YOSHIDA (Shinagawa Public Health Center), Takahiro TOYOZAWA (Yokohama Public Health Center). To identify the TB recurrence rate, we studied a cohort of 40 cases (treatment completion 36 cases, interruption 4 cases) of whom had a previous history of TB treatment including isoniazid and rifampicin. The time for relapse was 7.9 +/- 8.6 years and the overall relapse rate was 0.6% (0.47-0.7%). Our study suggested the relapse was almost equal to the low incident countries but the long-term follow-up and surveillance data should be carefully evaluated. 5.

    Paederus dermatitis is an unusual form of contact dermatitis caused by pederine, a secretion of insects belonging to the genus Paederus. These insects are found worldwide, although the concentration is higher in tropical and subtropical areas. Diagnosis is based on the presence of typical clinical features (erythematobullous lesions of sudden onset with a stinging, burning sensation on exposed areas of the body) combined with a compatible epidemiological context. In West Africa, more particularly in Guinea-Conakry, paederus dermatitis is common at the end of the rainy season. Our aim is to define the clinical and epidemiological characteristics of this disease. Herein we report data from a series of cases of paederus dermatitis among French expatriates living in Guinea-Conakry and attending the sociomedical center of the French Embassy at Conakry between October 20 and December 12, 2008. Seventy-four patients with the disease were included in the study (age range: 2-66; sex-ratio: 1:1). Most presented one or two lesions, with 36% of lesions situated on the face and neck region. Three patients presented with oculoconjunctival involvement. Complete remission occurred spontaneously within 8 to 10 days in 90% of patients. Systemic antibiotic therapy was initiated in less than 3% of patients. Preventive measures to repel the insects remain vital, in conjunction with curative methods (e.g. immediate cleansing of skin coming into contact with the irritant substance).

    Few studies exist about factors affecting the outcome of horses with tetanus. 31 equids (30 horses and 1 donkey) with a clinical diagnosis of tetanus admitted to the Equine Clinic of the University of Liege between 1991 and 2006. The cases were divided into two groups according to the outcome (survivors and non-survivors). The clinical data of survivors and non-survivors were compared using an ANOVA (continuous data) or a Fisher's test (discrete data). The survival rate was 32%. Most animals were 5 years or younger, and none had been appropriately vaccinated. The non-survivors were significantly younger than the survivors. The development of dyspnoea, recumbency, and the combination of dysphagia, dyspnoea, and recumbency was observed significantly more in the non-survivors than in the survivors. The timing of tetanus antitoxin administration (either immediately after the onset of suggestive signs or after a delay) was not different between the two groups. The time between the occurrence of a wound and the first signs ranged from 2 days to 2 months and was not significantly different between groups. All non-survivors died within 8 days of the first signs. This study suggests that young animals are affected more often and more severely by tetanus than older animals. Dyspnoea, recumbency, and the combination of dysphagia, dyspnoea, and recumbency can be considered as indicators of a poor prognosis in equids suffering from tetanus.

    Full Text Available OBJECTIVES: To investigate an unusual outbreak of tetrodotoxin poisoning in Leizhou, southeast China, a case series analysis was conducted to identify the source of illness. METHODS: A total of 22 individuals experienced symptoms of poisoning, including tongue numbness, dizziness, nausea and limb numbness and weakness. Two toxic species, Amoya caninus and Yongeichthys nebulosus, were morphologically identified from the batches of gobies consumed by the patients. Tetrodotoxin levels in the blood and Goby fish samples were detected using liquid chromatography-tandem mass spectrometry. RESULTS: The tetrodotoxin levels in the remaining cooked Goby fish were determined to be 2090.12 µg/kg. For Amoya caninus, the toxicity levels were 1858.29 µg/kg in the muscle and 1997.19 µg/kg in the viscera and for Yongeichthys nebulosus, they were 2783.00 µg/kg in the muscle and 2966.21 µg/kg in the viscera. CONCLUSION: This outbreak demonstrates an underestimation of the risk of Goby fish poisoning. Furthermore, the relationships among the toxic species, climates and marine algae present should be clarified in the future.

    Medical records of cats with high-rise trauma were reviewed to document the prevalence and clinical manifestations of orofacial injury. Cats were presented over a 10-year period from January 2000 to December 2009. Signalment, weight, number of stories fallen, and survival data were recorded in 84 cats and physical examination findings were obtained from 83 cats. Fourteen of these cats were examined by veterinarians of the Dentistry and Oral Surgery Service. Mean age was 37-months. Mean distance fallen was 2.65 stories, and in the majority of cases the substrate the cat fell on was not recorded Overall, survival was 94.0% when including euthanasia as a cause of death and 98.8% when excluding euthanized patients. Orofacial findings included bilateral epistaxis, hard palate fracture +/- tear of palatal soft tissue, palatal soft tissue bruising, mandibular fracture, mandibular symphyseal separation, tongue injury, facial soft tissue injury, dental trauma, and other oral soft tissue injury. Sixty-six percent of cats suffered some degree of orofacial injury. The population was analyzed for the prevalence of each type of injury. An oronasal fistula was seen in one cat as a complication of an untreated hard palate fracture. Possible etiology of the injuries and treatment options are discussed.

    In 1987 the Swedish Dental Act was amended to allow Swedish dentists who have undergone a specific accreditation course to administer intra-venous sedation. Midazolam is a benzodiazepin derivate with express sedative and hypnotic qualities, powerful amnesia, a short half-life time and few secondary effects. From 1989-1994 midazolam intravenous conscious sedation (ICS) was administered in 372 cases in the Department of Oral and Maxillofacial Surgery, County Hospital, Falun. This study presents data on the 298 patients. Although surgical removal of impacted wisdom teeth predominated, implant surgery, reduction of fractures and correction of anomalies were also carried out. Supplementary sedative premedication was rarely used. Most patients were treated under local anaesthesia. The mean dosage was 10.45 mg (range 1.25-40 mg). Mean dosage/kg was 0.15 mg (range 0.03-0.50 mg). The average duration of anaesthesia was 50 minutes. The average recovery time was 94 minutes. Three hundred and sixty-nine of 372 planned treatments were completed. No serious complications occurred. The patients were co-operative during surgery and were satisfied with the treatment. Compared with full anaesthesia this method required less resources and is a valuable complement in management of anxious patients undergoing oral surgery.

    Primary seborrhoea was diagnosed in 14 English springer spaniels over a 17-year period. Seven of the dogs developed clinical signs by two years of age. The dermatosis began as a generalised non-pruritic dry scaling which gradually worsened. Some dogs remained in this dry (seborrhoea sicca) stage, but in most cases the dermatosis became greasy and inflamed (seborrhoea oleosa and seborrhoeic dermatitis). Eight of the dogs suffered from recurrent episodes of superficial or deep bacterial pyoderma. Histological findings in skin biopsy specimens included marked orthokeratotic hyperkeratosis of surface and infundibular epithelium, papillomatosis, parakeratotic capping of the papillae, and superficial perivascular dermatitis in which lymphocytes and mast cells were prominent. The dogs with seborrhoea sicca responded more satisfactorily to therapy with topical emollient-humectant agents or oral omega-3/omega-6 fatty acid supplementation. Dogs with seborrhoea oleosa and seborrhoeic dermatitis did not respond satisfactorily to topical therapy. One dog, however, responded well to etretinate and omega-3/omega-6 fatty acid administration. No dog was cured.

    The objective of this retrospective analysis is to systematically assess osseous lesions on the basis of a validated scoring system in terms of stability and fractures prior to and following radiotherapy in 338 lung cancer patients with bone metastases in the vertebral column. The stability of 338 patients with 981 osteolytic metastases in the thoracic and lumbar spine was evaluated retrospectively on the basis of the Taneichi-Score between January 2000 and January 2012. 64% (215 patients) were classified stable prior to radiotherapy. Of the stable osseous metastases, none were rated unstable in the further course (p < 0.001, McNemar test). Of the 123 patients in whom the metastases were classified unstable prior to radiotherapy, 21 patients (17%) were classified stable after three months, and 30 patients (24%) stable after six months. A pathological fracture was diagnosed in 62 patients (18%) prior to radiotherapy. Regarding cases of osteolytic metastases of the vertebral bodies in which no fractures could be detected prior to the start of therapy, fractures occurred in 2% of all patients (n = 7) within six months following radiotherapy. Our analysis demonstrated that pathological fractures following radiotherapy occur in the very minority of vertebral lesions for patients with a favorable outcome. The use of a systematic radiological scoring system to classify osteolytic metastases of the vertebral column has shown to be feasible in daily routine. Prospective clinical trials are warranted in order to analyse, to what extent patients with osseous metastases can be mobilized by physiotherapy for strengthening the paravertebral muscles before radiotherapy effects can be measured by means of radiological recalcification

    Full Text Available Steven Douglas Maynard,1,2 Jeff Gelblum31Union Associated Physicians Clinic, 2Indiana University School of Medicine, Terre Haute, IN, 3Mt Sinai Medical Center of Miami, Aventura Hospital, Aventura, FL, USAAbstract: Under normal conditions, the adult human brain is fueled primarily by glucose. A prominent feature of Alzheimer's disease (AD is region-specific decreases in cerebral glucose metabolism. Ketone bodies are a group of compounds produced from fat stores during periods of low glucose availability that can provide an alternative to glucose for brain metabolism. Consumption of sufficient quantities of caprylic triglyceride (CT increases plasma concentrations of ketone bodies and may be beneficial in conditions of compromised glucose metabolism, such as AD. The present study describes the use of CT in mild-to-moderate AD in routine clinical practice. Case records from eight patients with extensive monitoring of cognitive function using the Mini-Mental State Examination (MMSE and who had received CT for ≥6 months were reviewed. All were outpatients aged ≥50 years, cared for in standard practice, had a diagnosis of probable AD of mild-to-moderate severity (MMSE 14–24, and had received CT for at least 6 months in addition to other approved pharmacotherapy for AD. Response to CT administration as measured by MMSE scores varied by patient. However, the rate of decline in MMSE scores appeared slower than previously published reports for patients treated with pharmacotherapy alone. Profiling of individual patients may provide insight regarding those most likely to benefit from addition of CT to currently approved AD pharmacotherapy.Keywords: ketosis, cognition, Alzheimer's disease, metabolism, glucose

    Full Text Available Study Design: Retrospective study. Objective: The aim was to find out whether intraoperative three-dimensional imaging after transpedicular positioning of Kirschner wire (K-wire in lumbar and thoracic posterior instrumentation procedures is of benefit to the patients and if this technique is accurately enough to make a postoperative screw position control through computer tomography (CT dispensable. Patients and Methods: Lumbar and thoracic posterior instrumentation procedures conducted at our department between 2002 and 2012 were retrospectively reviewed. The patients were divided into two groups: group A, including patients who underwent intraoperative three-dimensional scan after transpedicular positioning of the K-wire and group B, including patients who underwent only intraoperative biplanar fluoroscopy. An early postoperative CT of the instrumented section was done in all cases to assess the screw position. The rate of immediate intraoperative correction of the K-wires in cases of mal-positioning, as well as the rate of postoperative screw revisions, was measured. Results: In general, 345 patients (1880 screws were reviewed and divided into two groups; group A with 225 patients (1218 screws and group B with 120 patients (662 screws. One patient (0.44% (one screw [0.082%] of group A underwent postoperative screw correction while screw revisions were necessary in 14 patients (11.7% (28 screws [4.2%] of group B. Twenty-three patients (10.2% (28 K-wires [2.3%] of group A underwent intraoperative correction due to primary intraoperative detected K-wire mal-position. None of the corrected K-wires resulted in a corresponding neurological deficit. Conclusion: Three-dimensional imaging after transpedicular K-wire positioning leads to solid intraoperative identification of misplaced K-wires prior to screw placement and reduces screw revision rates compared with conventional fluoroscopic control. When no clinical deterioration emerges, a

    Telemedicine using cellular phones allows for real-time consultation of burn patients seen at distant hospitals. Telephonic consultations to our unit have required completion of a proforma, to ensure collection of the following information: demographics, mechanism of injury, vital signs, relevant laboratory data, management at the referring hospital and advice given by the burn team. Since December 2014 we have required referring doctors to send photographs of the burn wounds to the burns specialist before making a decision on acceptance of the referral or providing management advice. The photographs are taken and sent by smartphone using MMS or WhatsApp. The cases, with photographs, are entered into a database of telemedicine consultations which we have retrospectively reviewed. During the study period (December 2014-July 2015) we were consulted about 119 patients, in 100 of whom the telemedicine consultation was completed. Inappropriate transfer to the burns centre was avoided in 38% of cases, and in 28% a period of treatment in the referral hospital was advised before transfer. For a total of 66% of patients the telemedicine consultation changed, and either avoided an inappropriate admission, or delayed admission in late referrals until the patient was ready for definitive treatment. We conclude that telemedicine consultations using a cellular phone significantly change referral pathways in burns. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

    To describe all the CT findings after in situ contrast injection just before steroid injection and to recognize the abnormal aspects associated with intravascular contamination. We retrospectively evaluated 248 cervical transforaminal steroid injections done at the university hospital in Dijon, France, in 2008-2012, to treat cervicobrachial neuralgia inadequately improved by optimal medical treatment for at least 3 weeks. Features describing the opacification patterns were recorded. Five main nonvascular opacification patterns were identified: clumps of contrast agent outside the foramen (16 %), a crab claw pattern surrounding the ganglion (13 %), a ''French'' circumflex accent pattern (15 %), reflux along the needle (7 %), and facet joint capsule opacification (22 %). Concerning the situations requiring a change in needle position, intravenous injection occurred in 26 % of the patients, with a crab claw pattern in half the cases and a clump pattern in half the cases. Intraarteriolar injection was noted in two patients. CT after in situ contrast injection ensures proper needle positioning outside the blood vessels before steroid injection. Penetration of the needle tip into a vein is very common, whereas arteriolar puncture is extremely rare. (orig.)

    Full Text Available Background: In the treatment of active tuberculosis, therapeutic drug monitoring (TDM is used to optimize dosing that maximizes therapeutic benefit while minimizing toxicity. In Morocco, TDM is not routinely used, yet low levels of anti-TB drugs can be associated with poorer treatment outcomes.Methods: We retrospectively checked our archives for patients with active TB for whom TDM was performed during 2014. Medical records were reviewed to abstract demographic, clinical, radiographic and microbiological data including time until smear and culture conversion. Then, we looked for cases with delay of TB conversion.Results: In total, 24 patients were identified, for whom TDM was performed, they all had low serum drug levels. Among them, 4 patients showed delayed bacteriological conversion.Conclusions: Our study cases are showing the benefit of serum dosage in the follow-up of the patients showing a delay of sputum examination conversion, both direct and culture, during their evolutions. TDM is potentially useful for the treatment of active TB, but is currently underused in Morocco.

    Airborne allergic contact dermatitis caused by paints containing isothiazolinones has been recognized as a health hazard. To collect epidemiological, clinical and patch test data on airborne allergic contact dermatitis caused by isothiazolinone-containing paints in France and Belgium. A descriptive, retrospective study was initiated by the Dermatology and Allergy Group of the French Society of Dermatology, including methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI)- and/or MI-sensitized patients who developed airborne allergic contact dermatitis following exposure to isothiazolinone-containing paint. Forty-four cases were identified, with mostly non-occupational exposure (79.5%). Of the patients, 22.5% of also had mucosal symptoms. In several cases, the dermatitis required systemic corticosteroids (27.3%), hospitalization (9.1%), and/or sick leave (20.5%). A median delay of 5.5 weeks was necessary to enable patients to enter a freshly painted room without a flare-up of their dermatitis. Approximately one-fifth of the patients knew that they were allergic to MI and/or MCI/MI before the exposure to paints occurred. Our series confirms that airborne allergic contact dermatitis caused by paints containing isothiazolinones is not rare, and may be severe and long-lasting. Better regulation of isothiazolinone concentrations in paints, and their adequate labelling, is urgently needed. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Neuroleptic malignant syndrome (NMS) is a neurological emergency rarely encountered in clinical practice but with a high mortality rate. Cases associated with atypical antipsychotic use or termination of dopamine agonists have been seen in recent years. The purpose of this study was to assess the presence of risk factors for mortality by investigating all clinical and laboratory characteristics of cases with NMS. This descriptive, cross-sectional study retrospectively investigated all clinical and laboratory characteristics by scanning the ICD-10 codes of patients presenting to the XXXX Faculty of Medicine Emergency Department and diagnosed with NMS between 2006 and 2016. Patients were divided into surviving and non-surviving groups, and the data elicited were subjected to statistical comparisons. The mean age of the 18 patients diagnosed with NMS was 46.9 ± 4.8 years, and 50% were women. In addition to antipsychotics among the drugs leading to NMS, the syndrome also developed as a result of levodopa withdrawal in three patients and metoclopramide use in one patient. Statistically significant differences were determined between the surviving and non-surviving patients in terms of blood pressure, blood urea nitrogen (BUN), creatine kinase (CK) and mean platelet volume (MPV) values (p ≤ 0.05). In this study the most common agent that cause NMS was atypical antipsychotics. Also advanced age, increased blood pressure and serum CK, BUN and MPV values were identified as potential risk factors for mortality in NMS.

    Objective: to evaluate the necessity of the non contrast-enhanced phase in abdominal computed tomography scans. Materials and Methods: A retrospective, cross-sectional, observational study was developed, evaluating 244 consecutive abdominal computed tomography scans both with and without contrast injection. Initially, the contrast-enhanced images were analyzed (first analysis). Subsequently, the observers had access to the non-contrast-enhanced images for a second analysis. The primary and secondary diagnoses were established as a function of the clinical indications for each study (such as tumor staging, acute abdomen, investigation for abdominal collection and hepatocellular carcinoma, among others). Finally, the changes in the diagnoses resulting from the addition of the non-contrast-enhanced phase were evaluated. Results: Only one (0.4%; p > 0.999; non-statistically significant) out of the 244 reviewed cases had the diagnosis changed after the reading of non-contrast-enhanced images. As the secondary diagnoses are considered, 35 (14%) cases presented changes after the second analysis, as follows: nephrolithiasis (10%), steatosis (3%), adrenal nodule (0.7%) and cholelithiasis (0.3%). Conclusion: For the clinical indications of tumor staging, acute abdomen, investigation of abdominal collections and hepatocellular carcinoma, the non-contrast-enhanced phase can be excluded from abdominal computed tomography studies with no significant impact on the diagnosis.

    Results: The initial symptoms varied considerably, with nausea and vomiting (13/56, 23% being the most common. Liver-function indexes were remarkable, including elevated levels of serum alanine aminotransferase (262.16 ± 281.71 U/L, aspartate aminotransferase (260.98 ± 237.91 U/L, lactic dehydrogenase (1011.76 ± 530.34 U/L, and direct bilirubin (85.59 ± 90.02 μmol/L. Coagulation disorders were indicated by abnormal levels of fibrinogen (245.95 ± 186.11 mg/dL, D-dimer (2.46 ± 4.01 mg/L, and fibrin degradation products (43.62 ± 48.71 mg/L. The main maternal complications were hypoproteinemia (75%, coagulopathy (54%, and acute renal failure (39%. Multivariate logistic regression analysis identified prothrombin time (PT; odds ratio [OR] = 1.558, 95% confidence interval [CI] =1.248–1.946, PORCIP= 0.009 as risk factors. The perinatal infant death rate was related to gestational age at delivery (ORCI PORCI PORCI PConclusions: Nausea and vomiting may be the most common symptoms of AFLP. Indexes of liver dysfunction and coagulation disorders should also be considered. PT and INR are risk factors for fatal complications in patients with AFLP, and perinatal mortality is linked to the level of fibrin degradation products. Timely delivery is crucial to controlling the development of AFLP.

  5. The case for moderate gun control.

    In addressing the shape of appropriate gun policy, this essay assumes for the sake of discussion that there is a legal and moral right to private gun ownership. My thesis is that, against the background of this right, the most defensible policy approach in the United States would feature moderate gun control. The first section summarizes the American gun control status quo and characterizes what I call "moderate gun control." The next section states and rebuts six leading arguments against this general approach to gun policy. The section that follows presents a positive case for moderate gun control that emphasizes safety in the home and society as well as rights whose enforcement entails some limits or qualifications on the right to bear arms. A final section shows how the recommended gun regulations address legitimate purposes, rather than imposing arbitrary restrictions on gun rights, and offers concluding reflections.

    Case-control studies are commonly used to evaluate effectiveness of licensed vaccines after deployment in public health programs. Such studies can provide policy-relevant data on vaccine performance under 'real world' conditions, contributing to the evidence base to support and sustain introduction of new vaccines. However, case-control studies do not measure the impact of vaccine introduction on disease at a population level, and are subject to bias and confounding, which may lead to inaccurate results that can misinform policy decisions. In 2012, a group of experts met to review recent experience with case-control studies evaluating the effectiveness of several vaccines; here we summarize the recommendations of that group regarding best practices for planning, design and enrollment of cases and controls. Rigorous planning and preparation should focus on understanding the study context including healthcare-seeking and vaccination practices. Case-control vaccine effectiveness studies are best carried out soon after vaccine introduction because high coverage creates strong potential for confounding. Endpoints specific to the vaccine target are preferable to non-specific clinical syndromes since the proportion of non-specific outcomes preventable through vaccination may vary over time and place, leading to potentially confusing results. Controls should be representative of the source population from which cases arise, and are generally recruited from the community or health facilities where cases are enrolled. Matching of controls to cases for potential confounding factors is commonly used, although should be reserved for a limited number of key variables believed to be linked to both vaccination and disease. Case-control vaccine effectiveness studies can provide information useful to guide policy decisions and vaccine development, however rigorous preparation and design is essential.

    Chronic prostatitis (CP) does not yet have a universally successful therapy. Alternative treatments including thermotherapy have been adopted in the multimodal management of pain and voiding dysfunction. We retrospectively analyzed the therapeutic efficacy of bipolar radiofrequency thermotherapy for patients who were unsatisfied with conventional medication for CP. A retrospective study between October 2009 and September 2010 of 26 patients who were under 50 years old and diagnosed with CP (National Institutes of Health [NIH]-category III) was performed. Twenty patients were diagnosed with inflammatory CP (NIH-category IIIa) and the rest with noninflammatory CP (NIH-category IIIb). We used the Tempro system at an intraprostatic temperature of 55℃ for 50 minutes with a medium heating rate. All patients also completed the NIH-Chronic Prostatitis Symptom Index (CPSI) before and after treatment. In the patients diagnosed with CP, the mean serum prostate-specific antigen (PSA) level was 0.9±0.3 ng/ml, the prostate volume was 27.1±5.5 g, and the average score for all 3 domains on the NIH-CPSI significantly decreased. The total scores decreased from 19.8±7.1 to 11.1±7.0, the pain domain decreased from 8.6±3.1 to 4.8±3.1, the voiding symptom domain decreased from 5.1±1.8 to 2.9±1.8, and the effect on the quality of life decreased from 6.1±2.2 to 3.4±2.2 (pthermotherapy for patients with CP intractable to conventional medication can provide significant improvement in the NIH-CPSI. Large, randomized controlled trials will also be required to confirm the efficacy of this therapy.

    to measure the magnitude of eclampsia and its maternal and perinatal outcome. A 5 years retrospective descriptive study was conducted on 216 eclamptic cases diagnosed, admitted and managed from October 1994 to September 1999 in the two teaching hospitals of Addis Ababa; namely Tikur Anbessa and St Paul's Hospitals. There were 257 mothers with eclampsia treated in the given period and 35741 deliveries making the incidence of eclampsia 7.1/1000 deliveries. Eighty-four women (38.9%) had any antenatal care, 157 (72.7%) were nulli-parous and 69 (31.8%) were aged below 20. Convulsion occurred ante-partum in 133 (61.6%), intrapartum in 49 (22.7%) and postpartum in 34 (15.7%) mothers. The most frequently sited symptoms before convulsion include headache in 83.8%, visual disturbance in 41.6% and epigastric pain in 38.4% of the cases. Ninety nine (45.8%) women were delivered by cesarean section making the cesarean section rate among eclamptic mothers significantly higher than the rate among the general population, which was 16.6% at the same period. (P = 0.0001). The multiple pregnancy rate was 5.7%, which was significantly higher than the rate among the general population of 1.5% at the same time. Seventy-four mothers had repeated convulsion after admission to the hospitals and initiation of the standard treatment. Twenty-eight mothers with eclampsia died making the case fatality rate 13%. Seven mothers (3.2%) died before delivery. Forty-four Stillbirths and twenty-five early neonatal deaths occurred making the perinatal mortality rate 312.2/1000 deliveries. Eclampsia is a common complication still associated with high level of maternal and perinatal mortality as well as morbidity. ANC coverage should be strengthened to detect preclampsia, and prevent eclampsia. Management in the hospital should be optimized to prevent recurrent convulsions and complications after admission.

    Endoscopic transnasal approaches to the skull base have revolutionized the treatment of cerebrospinal fluid (CSF) fistulae, making repair less invasive and more effective compared with craniotomy or extracranial techniques. This study evaluated, retrospectively, the results of endoscopic repair of dural defects with the use of mucoperiostal grafts taken from the lower turbinate. Between January 1997 and January 2007, 125 cases of anterior skull base CSF fistulae were treated endoscopically at the Instituto Felippu de Otorrinolaringologia, Sao Paolo, Brazil, and at the Department of Otolaryngology of the University Hospital "Ospedali Riuniti", Foggia, Italy. Fistula closure was achieved by overlay apposition of a lower turbinate mucoperiostal graft fixated with fibrin glue and Surgicell. The etiology of the fistula was accidental trauma in 41 cases, iatrogenic trauma in 29, skull base tumour in 12, and spontaneous in 43. The site of the defect was the sphenoid sinus in 43 patients, the cribriform plate in 42, the anterior ethmoid roof in 21, the posterior ethmoid roof in 17, and the posterior wall of the frontal sinus in 2. The success rate at first attempt was 94.4%; the 7 cases of postoperative recurrent CSF leakage involved patients presenting with spontaneous fistula and elevated intracranial pressure; 5 of these had a body-mass index > 30 and 3 suffered from diabetes mellitus. In our hands, the success rate of endoscopic fistula repair was high, even in defects larger than 2 cm. Success rates may be further improved with accurate diagnosis of elevated intracranial pressure, a contributing factor to failure of spontaneous fistula repair.

    The authors report on the retrospective analysis of 19 patients with primary cerebral germ cell tumors which were treated between 1965 and 1993. Median age is 18 years (extremes: 16-55 years). There were 16 men and three women. The location of the primary tumor was the pineal area in six patients, suprasellar and hypothalamic area in five patients and other areas in eight patients. The histological pattern was non seminoma in six patients, dysgerminoma in eight; however no histological sample was obtained in five patients who did not have any particular characteristics (either cytological abnormalities or elevated tumor marker level). Three patients were treated by surgery only, eight patients received exclusive radiotherapy and eight patients had first line chemotherapy and further cranial irradiation. One was lost to follow up. Six of eight assessable patients with dysgerminoma are alive with non evolutive disease (NED) after 15 to 176 month of follow-up. One out of five assessable patients with non seminomatous tumor in NED (163 month of follow-up). Finally all five patients who have no histological subtyping are alive with NED at 24 to 138 months. The standard treatment of dysgerminoma is currently first line chemotherapy followed by relatively low-dose and limited irradiation; the standard treatment of non-seminomatous cerebral germ cell tumor is chemotherapy, the study of which is warranted with the aim to decrease the toxicity and to increase the efficacy.

    Although lateral epicondylitis (LE) is a very common tendinopathy, we understand little about the etiology of the disease. Tobacco use has been associated with other tendinopathies, and the purpose of this study is to determine if there is an association between the incidence of lateral epicondylitis and tobacco use. We performed a retrospective cohort study of adult patients diagnosed with lateral epicondylitis. Patients from a single orthopaedic surgeon's practice with LE were matched to control patients with other common upper extremity conditions based on age, gender, and occupation. A total of 65 case patients and 217 control patients were included in the study. The incidence of smoking in patients with lateral epicondylitis was compared to the incidence of smoking in the control group. Of the LE patients, 30/65 (46.2%) were non-smokers, 23/65 (35.4%) were former smokers, and 12/65 (18.5%) were current smokers. Of the control patients, 121/217 (55.8%) were non-smokers, 45/217 (20.7%) were former smokers, and 51/217 (23.5%) were current smokers. The odds of LE patients being former or current smokers compared to control patients were 1.45 times higher, but this was not statistically significant. Among people who did not smoke at the time of presentation, the odds of being a former smoker were 2.28 times higher in LE patients than in controls, which was statistically significant. The odds of being a former smoker were significantly higher in patients with lateral epicondylitis compared to patients with other upper extremity conditions. Although it did not reach statistical significance, the odds of being former or current smokers were also higher in the LE group. These results suggest a relationship between smoking history and incidence of lateral epicondylitis, though more research is needed to determine the exact nature of the relationship. Prognostic, Level III.

    Malaria is a major public health problem and still reported among the 10 top causes of morbidity and mortality in Ethiopia. More than one-third of the people sought treatment from the private health sector. Evaluating adherences of health care providers to standards are paramount importance to determine the quality and the effectiveness of service delivery. Therefore, the aim of this study was to evaluate the contribution of public private mix (PPM) approach in improving quality of malaria case management among formal private providers. A retrospective data analysis was conducted using 2959 facility-months data collected from 110 PPM for malaria care facilities located in Amhara, Dire Dawa, Hareri, Oromia, Southern Nation Nationalities and Peoples and Tigray regions. Data abstraction formats were used to collect and collate the data on quarterly bases. The data were manually cleaned and analysed using Microsoft Office Excel 2010. To claim statistical significance non-parametric McNemar test was done and decision accepted at P < 0.05. From April 2012-September 2015, a total of 873,707 malaria suspected patients were identified, of which one-fourth (25.6 %) were treated as malaria cases. Among malaria suspected cases the proportion of malaria investigation improved from recorded in first quarter 87.7-100.0 % in last quarter (X(2) = 66.84, P < 0.001). The majority (96.0 %) were parasitologically-confirmed cases either by using microscopy or rapid diagnostic tests. The overall slid positivity rate was 25.1 % of which half (50.7 %) were positive for Plasmodium falciparum and slightly lower than half (45.2 %) for Plasmodium vivax; the remaining 8790 (4.1 %) showed mixed infections of P. falciparum and P. vivax. Adherence to appropriate treatment using artemether-lumefantrine (AL) was improved from 47.8 % in the first quarter to 95.7 % in the last quarter (X(2) = 12.89, P < 0.001). Similarly, proper patient management using chloroquine (CQ) was improved

    Case-control association studies often aim to investigate the role of genes and gene-environment interactions in terms of the underlying haplotypes (i.e., the combinations of alleles at multiple genetic loci along chromosomal regions). The goal of this article is to develop robust but efficient approaches to the estimation of disease odds-ratio parameters associated with haplotypes and haplotype-environment interactions. We consider "shrinkage" estimation techniques that can adaptively relax the model assumptions of Hardy-Weinberg-Equilibrium and gene-environment independence required by recently proposed efficient "retrospective" methods. Our proposal involves first development of a novel retrospective approach to the analysis of case-control data, one that is robust to the nature of the gene-environment distribution in the underlying population. Next, it involves shrinkage of the robust retrospective estimator toward a more precise, but model-dependent, retrospective estimator using novel empirical Bayes and penalized regression techniques. Methods for variance estimation are proposed based on asymptotic theories. Simulations and two data examples illustrate both the robustness and efficiency of the proposed methods.

    Syphilis may manifest as several distinct ophthalmological forms. The main objective of our study was to describe the diagnostic, therapeutic data and prognosis of ocular syphilis. We retrospectively analysed the cases of syphilitic uveitis diagnosed in the University Hospital of Nantes between 2000 and 2013. Twenty-seven patients were included in our study. Their mean age was 53.1 years. Bilateral uveitis was the most frequent clinical presentation (67%). The average diagnostic delay after the first symptoms was 2.8 months. Three patients (11%) presented with an anterior uveitis and 24 (89%) with a posterior uveitis, panuveitis or papillitis. The most frequent clinical signs were papillar lesion (44%), multifocal choroiditis (33%) and chorio-retinitis (37%). Ninety-three percent of the patients were treated with benzathine penicillin intravenously, one patient was treated by intramuscular penicillin injections and another by ceftriaxone intramuscularly. Ocular manifestations alone were sufficient to make the diagnosis of syphilis in 25 patients (93%) and of HIV seroconversion in 3 patients (11%). Forty-one percent of the patients benefited from an adjuvant therapy with corticosteroids. The treatment allowed a visual improvement of -0.48 log MAR (Psyphilis makes systematic screening in uveitis of a great value.

    Prevalence estimations for mitochondrial disorders still vary widely and only few epidemiologic studies have been carried out so far. With the present work we aim to give a comprehensive overview about frequencies of the most common mitochondrial mutations in Hungarian patients. A total of 1328 patients were tested between 1999 and 2012. Among them, 882 were screened for the m.3243A > G, m.8344A > G, m.8993T > C/G mutations and deletions, 446 for LHON primary mutations. The mutation frequency in our cohort was 2.61% for the m.3243A > G, 1.47% for the m.8344A > G, 17.94% for Leber's Hereditary Optic Neuropathy (m.3460G > A, m.11778G > A, m.14484T > C) and 0.45% for the m.8993T > C/G substitutions. Single mtDNA deletions were detected in 14.97%, while multiple deletions in 6.01% of the cases. The mutation frequency in Hungarian patients suggestive of mitochondrial disease was similar to other Caucasian populations. Further retrospective studies of different populations are needed in order to accurately assess the importance of mitochondrial diseases and manage these patients.

    Full Text Available The aim of the study is to analyze all completely excised BCCs in the head and neck region with regard to age, sex, personal and familial history, skin type, tumor localization and size, histopathological subtype of tumor, reconstruction method, and recurrence rates. Incompletely excised BCCs were not included in this study since incomplete excision is the most important preventable risk factor for recurrence. In 320 patients, 331 lesions were retrospectively evaluated by dividing into the following 8 subunits: scalp, frontotemporal, orbital, nose, cheek, auricula, perioral, and chin-neck area. Most of the patients were in 60–70 age group (34.7%. The nose (32.3% was the most common site of presentation. Clinically, all lesions and, histopathologically, most of the lesions (42.2% presented were of the nodular type. All cases of recurrence after complete excision (n=9, 2.7% were located in the median parts of the head and neck region and were mainly diagnosed histopathologically as sclerotic and micronodular. Even though completely excised, head and neck region BCCs, especially which are more prone to recurrence due to anatomical and histopathological properties, should be more closely monitored in order to decrease morbidity and health care costs.

    The purposes of this retrospective study were to review cases of colonic torsion/volvulus between July 1992 and August 2010 and to determine if any predisposing factors exist for the development of this condition. Six dogs were diagnosed with colonic torsion/volvulus during the study period. Four dogs had a history of previous gastric dilation-volvulus (GDV) with prophylactic gastropexy. Three of six dogs diagnosed with colonic torsion/volvulus had large intestinal entrapment and strangulation around the gastropexy site at the time of surgery. The history, clinical signs, physical examination, and radiologic findings were not specific for colonic torsion/volvulus in any dog. Early exploratory laparotomy was indicated to confirm the diagnosis and perform surgical correction of the affected bowel segments. Three of five dogs that underwent surgery had a left abdominal wall colopexy performed. All five dogs that underwent surgery in this study survived postoperatively. One patient was euthanized without surgical intervention. Results suggest that colonic torsion/volvulus should be considered in any large-breed dog with nonspecific gastrointestinal clinical signs and a history of previous gastropexy. Early recognition and prompt treatment of this condition may result in a good outcome.

    Our aim was to summarise the clinical characteristics and presentation of ameloblastomas in eastern Nigeria. We organised a retrospective study of 240 patients who presented with ameloblastomas to the Oral and Maxillofacial Surgery units of five specialist hospitals in the eastern states of Nigeria over an eight-year period (2004-2011). We analysed the casenotes, and categorised the cases by site of tumour, age, sex, and time of presentation. There were 117 men (49%) (mean (SD) age 43 (6.2) years) and 123 women (51%) (mean (SD) age 32 (4.7) years), a male:female ratio of 1:1.1. The largest age group was 20-39 years (n=102, 43%), and the most common site was the anterior mandible (n=140, 58%). Most of the patients presented late. Our results show that the most common site of ameloblastomas in Eastern Nigeria is the anterior mandible and that women are affected more than men, which is at variance with the results of most other studies.

    The use of blood products in 1480 consecutive cases of adult cardiac surgical procedures over a period of 15 mth was studied retrospectively using the database of the Department of Anaesthesia of the Institut de Cardiologie de Montréal. Use of blood products was compared in patients having (1) coronary artery bypass grafting, (2) valvular surgery, (3) or a combination of 1 and 2. First operations were compared with reoperations. Overall, the use of homologous blood products was greatest in patients of Group 3, intermediate in patients of Group 2, and smallest in patients of Group 1. Reoperations were associated with an increase in intraoperative transfusion of packed red blood cells, but postoperative chest drainage was similar to first operations. When all blood products (packed red blood cells, fresh frozen plasma and platelets) were taken into consideration, patients undergoing primary CABG or valve surgery were the least exposed to homologous blood donors (five and six units transfused respectively). Repeat CABG was associated with an intermediate exposure to homologous blood products (eight units). Finally, primary and repeat combined procedures, and repeat valve surgery were associated with the greatest exposure to foreign blood products (10, 13 and 10 units respectively). The data presented in this study provide a rational basis for stratification of procedures according to the expected use of blood products, particularly in view of future studies which may be planned to examine the efficiency of blood conservation strategies.

    Bleeding management in cardiac surgery is challenging. Many guidelines exist to support bleeding management; however, literature demonstrates wide variation in practice. In 2012, a quality initiative was undertaken at The Prince Charles Hospital, Australia to improve bleeding management for cardiac surgery patients. The implementation of the quality initiative resulted in significant reductions in the incidence of blood transfusion, re-exploration for bleeding; superficial leg and chest wound infections; length of hospital stay, and cost. Given the success of the initiative, we sought to answer the question; "How and why was the process of implementing a bleeding management quality initiative in the cardiac surgery unit successful, and sustainable?" A retrospective explanatory case study design was chosen to explore the quality initiative. Analysis of the evidence was reviewed through phases of the 'Knowledgeto Action' planned change model. Data was derived from: (1) document analysis, (2) direct observation of the local environment, (3) clinical narratives from interviews, and analysed with a triangulation approach. The study period extended from 10/2011 to 6/2013. Results demonstrated the complexity of changing practice, as well as the significant amount of dedicated time and effort required to support individual, department and system wide change. Results suggest that while many clinicians were aware of the potential to apply improved practice, numerous barriers and challenges needed to be overcome to implement change across multiple disciplines and departments. The key successful components of the QI were revealed through the case study analysis as: (1) an appropriately skilled project manager to facilitate the implementation process; (2) tools to support changes in workflow and decision making including a bleeding management treatment algorithm with POCCTs; (3) strong clinical leadership from the multidisciplinary team and; (4) the evolution of the project

    Mucocutaneous lesions directly related to human immunodeficiency virus (HIV) infection usually present as initial manifestations of immune deficiency. The most common mucocutaneous lesions are Kaposi's sarcoma, histoplasmosis, oro-esophageal candidiasis, oral hairy leukoplakia, and, in Asia, Penicillium marneffei infection. Non-HIV-related skin lesions, such as psoriasis, seborrheic dermatitis, and nodular prurigo, may be the initial presentation among HIV infected patients attending outpatient clinics. A retrospective analysis was performed on 145 HIV-positive Malaysians of Chinese descent from two centers at the University Hospital Kuala Lumpur (UHKL) and the General Hospital Kuala Lumpur (GHKL) from March 1997 to February 1998. Demographic data and clinical data were analyzed. The analysis showed that 104 out of 145 patients had mucocutaneous disorders (71.7%). In the study, there were 100 men (96.2%) and four women (3.8%). The majority of patients were in the age group 20-50 years. The patients who presented with mucocutaneous disease also had low CD4+ T-lymphocyte counts and most had acquired immunodeficiency syndrome (AIDS) defining illness. The number of cases with generalized hyperpigmentation was very high in the group (35.9%), followed by nodular prurigo (29.7%) and xerosis (27.6%). Seborrheic dermatitis was seen in 20.7% of cases, with psoriasis in 8.3%. The most common infections were oral candidiasis (35.9%), tinea corporis and onychomycosis (9.7%), and herpes infection (5.5%); however, mucocutaneous manifestations of Kaposi's sarcoma were rare. The results suggest that mucocutaneous findings are useful clinical predictors of HIV infection or signs of the presence of advanced HIV infection.

    Full Text Available Abstract Background Acute kidney injury is among the most serious complications after cardiac surgery and is associated with an impaired outcome. Multiple factors may concur in the development of this disease. Moreover, severe renal failure requiring renal replacement therapy (RRT presents a high mortality rate. Consequently, we studied a Spanish cohort of patients to assess the risk factors for RRT in cardiac surgery-associated acute kidney injury (CSA-AKI. Methods A retrospective case-cohort study in 24 Spanish hospitals. All cases of RRT after cardiac surgery in 2007 were matched in a crude ratio of 1:4 consecutive patients based on age, sex, treated in the same year, at the same hospital and by the same group of surgeons. Results We analyzed the data from 864 patients enrolled in 2007. In multivariate analysis, severe acute kidney injury requiring postoperative RRT was significantly associated with the following variables: lower glomerular filtration rates, less basal haemoglobin, lower left ventricular ejection fraction, diabetes, prior diuretic treatment, urgent surgery, longer aortic cross clamp times, intraoperative administration of aprotinin, and increased number of packed red blood cells (PRBC transfused. When we conducted a propensity analysis using best-matched of 137 available pairs of patients, prior diuretic treatment, longer aortic cross clamp times and number of PRBC transfused were significantly associated with CSA-AKI. Patients requiring RRT needed longer hospital stays, and suffered higher mortality rates. Conclusion Cardiac-surgery associated acute kidney injury requiring RRT is associated with worse outcomes. For this reason, modifiable risk factors should be optimised and higher risk patients for acute kidney injury should be identified before undertaking cardiac surgery.

    The main aim of the study was to describe the features and diagnoses of a population of cats referred with pyrexia. Other aims were to report and evaluate the utility of clinical investigations performed, and describe any effect of treatment before referral on temperature at presentation and ability to make a diagnosis. Clinical records of cats with pyrexia (⩾39.2°C) documented at least twice were retrospectively reviewed. Cases were assigned to disease categories (infectious, inflammatory, immune-mediated, neoplastic, miscellaneous and no diagnosis [pyrexia of unknown origin, PUO]) based on diagnosis. The overall value of clinical investigations was assessed by classifying them as 'enabling', 'assisting' or 'no assistance' in achieving each diagnosis. The effect of treatment before referral was assessed for any association with temperature at presentation and ability to make a diagnosis (PUO vs other disease categories). One hundred and six cases were identified. The most common cause of pyrexia was feline infectious peritonitis (22 cats, 20.8%) and the largest disease category was infectious (41/106, 38.7%). Inflammatory conditions were found in 19 (17.9%) cats, neoplasia in 13 (12.3%), miscellaneous causes in 11 (10.4%) and immune-mediated disease in six (5.7%). No diagnosis was reached in 16 (15.0%) cats, often despite extensive diagnostic investigations. Cytology and histopathology most often 'enabled' or 'assisted' in obtaining a diagnosis. Most cats (91, 85.8%) received treatment before referral, with antimicrobial treatment given to 87 (82.1%). Prior treatment before referral was not associated with temperature at presentation nor with success in establishing a diagnosis. This is the first study investigating causes of pyrexia in cats. Infectious diseases were most common and immune-mediated diseases were comparatively rare.

    Full Text Available Objective: Neuroleptic malignant syndrome (NMS is a neurological emergency rarely encountered in clinical practice but with a high mortality rate. Cases associated with atypical antipsychotic use or termination of dopamine agonists have been seen in recent years. The purpose of this study was to assess the presence of risk factors for mortality by investigating all clinical and laboratory characteristics of cases with NMS. Material and methods: This descriptive, cross-sectional study retrospectively investigated all clinical and laboratory characteristics by scanning the ICD-10 codes of patients presenting to the XXXX Faculty of Medicine Emergency Department and diagnosed with NMS between 2006 and 2016. Patients were divided into surviving and non-surviving groups, and the data elicited were subjected to statistical comparisons. Results: The mean age of the 18 patients diagnosed with NMS was 46.9 ± 4.8 years, and 50% were women. In addition to antipsychotics among the drugs leading to NMS, the syndrome also developed as a result of levodopa withdrawal in three patients and metoclopramide use in one patient. Statistically significant differences were determined between the surviving and non-surviving patients in terms of blood pressure, blood urea nitrogen (BUN, creatine kinase (CK and mean platelet volume (MPV values (p ≤ 0.05. Conclusion: In this study the most common agent that cause NMS was atypical antipsychotics. Also advanced age, increased blood pressure and serum CK, BUN and MPV values were identified as potential risk factors for mortality in NMS.

    Case cancellation (CC) has significant impact on the efficiency of operating room (OR) management, which can be mitigated by taking preventive measures. In this study, using the data of the West China Hospital (WCH), we identified the effect of contributing factors and recommended hospital interventions to facilitate CC prevention. We conducted a retrospective review of 11,331 elective surgical cases from January 1 to December 31, 2014. CC reasons were grouped into six categories. The methods of descriptive statistics and hypothesis test were used to identify the effect of factors. CC reasons (746) were divided into six broad categories: workup related (preoperative diagnostic assessment issues or sudden medical condition changes) (25.8%), non-specified reasons (25.8%), coordination issues (15.1%), patient related (13.0%), support system issues (11.8%), and doctor related (8.5%). The types of the most frequently performed operations are identified, as well as their CRs. The cancellation rate (CR) of males was lower than that of females (16.7% to 18.3%). A large difference in the CRs existed among doctors. The CR on Monday was significantly higher than the other four weekdays. Workup related issues, the types of procedures, the menstrual cycle of females, highly imbalanced CRs among doctors, and tendency of cancellation on Monday are the major identified factors, which account for a significant amount of preventable cancellations. It is suggested that corresponding hospital interventions can reduce CR and improve OR efficiency, including maintaining effective coordination, good communication and well-designed preoperative assessment processes, focusing on the type of procedures which are more time-consuming and complex, paying special attention to the physiology of females during surgery planning, taking measures to reduce CR of top eight doctors, and improving surgery scheduling on Monday.

    Full Text Available Background and Objective: The incidence of maxillofacial trauma is increasing at a very fast pace in developing countries like India and poses a major health burden. Hence, the epidemiological data of maxillofacial trauma during a 6 year period, was analyzed to study the characteristics, factors predisposing, and aid in advocating strict guidelines to prevent the same. Materials and Methods: Data related to 638 cases with maxillofacial trauma, from January 2008 to December 2014 were reviewed retrospectively and the data regarding gender, age, etiology, anatomic location of fracture, alcohol consumption, associated head and other injuries, modality of treatment rendered and associated complications were analyzed with descriptive statistics. Results: A total of 638 patients presenting with 869 maxillofacial fractures were analyzed. Most of them [344 (53.9%] were young adults aged 18-40, whereas, 123 (19.2% were 11 to 17 years, and 97(15.2% adults. Men (79.4% were more affected than women. Road traffic accidents remain the main etiology causing fractures in 470 (73.6%, whereas 397 (62.2% had history of consumption of alcohol. Those with alcohol intoxication had multiple injuries. Mandible was more frequently involved with 360 (41.4% fractures, and condyle being the most common site. A total of 374 (58.6% underwent open reduction with internal fixation under general anesthesia. Prevalence of other injuries was noted in 207 (32.4% and complications of fracture treatment in 41(6.4% cases. Conclusion: Road traffic accidents under alcohol influence were most commonly associated with comminuted facial fractures with head injuries, frequently leading to death. Mandible was the most commonly fractured facial bone followed by zygoma

    Parvovirus B19 causes erythema infectiosum in children, transient aplastic anemia in patients with hemoglobinopathies, pur red cell aplasia in immunocompromised persons and hydrops fetalis in pregnancy. The spectrum of clinical and biological manifestations in immunocompetent adult continues to grow up. We report on a case series of 26 patients with primary parvovirus B19 infection in immunocompetent adults. This is a retrospective study over the period 2000 to 2010 in two departments of internal medecine. The diagnostic was clinical, serological or molecular. There was a female predominance (sex-ratio 3.33/1). Median patient age at diagnostic was 38.8 years (range: 18-68). The predominant symptoms were fever (65%), peripheral and symmetrical polyarthralgia (62%) and skin rash (58%). Two patients had neurological manifestations (sixth cranial nerve palsy, distal paresthesia) and one patient had myocarditis. Abnormal laboratory values included increased acute phase reactants (73%), thrombocytopenia (43%), lymphopenia (38%) and elevated liver enzymes (37%). Antinuclear (19%), anti-DNA (28%) and anti-phospholipids antibodies (14%), and hypocomplementemia (32%) were observed. False reaction with anti-CMV and anti-EBV IgM positivity was documented in 27% of cases. Two patients had persistent parvovirus B19 infection. The diversity of the clinical manifestations of parvovirus B19 infection may be misleading for the clinician. However, the diagnosis should be suspected in immunocompetent adults to limit the risk of transmission to the patients who could develop a severe infection such as pregnant women or immunocompromised patients.

    Objective: To investigate clinical outcomes of laparoendoscopic single-site ovarian cystectomy compared with traditional multi-port laparoscopic ovarian cystectomy. Methods: Data of 81 patients with ovarian cystectomy from January 2016 to May 2017, the single-site group ( n= 40) and the multi-port group ( n= 41) in Peking Union Medical College Hospital were retrospectively collected. The outcomes of single-site and multi-port groups were analyzed and compared, including: postoperative fever, operation time, blood loss, hemoglobin change, surgical complications, postoperative pain score, postoperative analgesic requirements, body image scale and cosmetic score, length of hospital stay, postoperative total cost. Results: No complication was found in two groups. No difference was found in postoperative fever, blood loss, hemoglobin change, postoperative pain score, length of hospital stay, and total cost between the two groups (all P> 0.05). Operation time was (50±20) minutes in single-site group, and (40±15) minutes in multi-port group; postoperative analgesic requirements was 28%(11/40) in single-site group, and 7%(4/41) in multi-port group; cosmetic score was 22.6±2.6 in single-site group, and 17.3±2.6 in multi-port group; body image scale was 5.7±1.2 in single-site group, and 6.2±1.2 in multi-port group; these four clinical parameters were statistical differences (all P< 0.05). Conculsion: Laparoendoscopic single-site ovarian cystectomy is feasible and safe, although it could't relieve the postoperative pian, it do offer a higher cosmetic satisfaction.

    Full Text Available Abstract Background Delayed sleep phase disorder (DSPD is a condition in which patients have difficulty falling asleep before the early morning hours and commonly have trouble awakening before late morning or even early afternoon. Several studies have suggested that variations in habitual bedtime are 40–50% heritable. Methods We recruited a case series of 205 participants, along with 221 controls (DSPD-C with normal sleep, roughly matched for age, gender, and ancestry. A representative sample of San Diego adults recruited some years before was already available to confirm the control group. Both DSPD and DSPD-C provided blood or saliva samples for DNA and completed extensive questionnaires about sleep habits, sleep history, family history, sleep quality, morningness-eveningness traits, depression, mania, and seasonality of symptoms. The DSPD group wore wrist actigraphs for a median of 13.2 days. The representative sample collected previously had undergone actigraphic recordings, from which 48 hours of data were generally available. Results The DSPD and DSPD-C samples showed almost no overlap on morningness-eveningness scores. DSPD cases went to bed and arose about 3 hours later than the DSPD-C and the representative sample. DSPD cases reported more difficulties with sleep, poorer sleep quality, and more depression, but there was no significant difference in a history of mania. DSPD cases reported more family history of late bedtimes, but female DSPD reported that their fathers' bedtimes were later than the fathers of male DSPD. Conclusion These results indicate a DSPD phenotype is familial and associated with unipolar depression.

    After the last case of type 1 wild poliovirus (WPV1) was reported in 2007, Somalia experienced another outbreak of WPV1 (189 cases) in 2013. We conducted a retrospective, matched case-control study to evaluate the vaccine effectiveness (VE) of oral polio vaccine (OPV). We retrieved information from the Somalia Surveillance Database. A case was defined as any case of acute flaccid paralysis (AFP) with virological confirmation of WPV1. We selected two groups of controls for each case: non-polio AFP cases ("NPAFP controls") matched to WPV1 cases by age, date of onset of paralysis and region; and asymptomatic "neighborhood controls," matched by age. Using conditional logistic regression, we estimated the VE of OPV as (1-odds ratio)×100. We matched 99 WPV cases with 99 NPAFP controls and 134 WPV1 cases with 268 neighborhood controls. Using NPAFP controls, the overall VE was 70% (95% confidence interval [CI], 37-86), 59% (2-83) among 1-3 dose recipients, 77% (95% CI, 46-91) among ≥4 dose recipients. In neighborhood controls, the overall VE was 95% (95% CI, 84-98), 92% (72-98) among 1-3 dose recipients, and 97% (89-99) among ≥4 dose recipients. When the analysis was limited to cases and controls ≤24 months old, the overall VE in NPAFP and neighborhood controls was 95% (95% CI, 65-99) and 97% (95% CI, 76-100), respectively. Among individuals who were fully vaccinated with OPV, vaccination was effective at preventing WPV1 in Somalia.

    Studies defined as case-control do not always use this design. We aimed to estimate the frequency of mislabelled case-control studies in published articles in the area of diabetes and to identify the predictors of incorrect labelling. We searched Medline and Web of Science for articles with "diabetes" and "case control" in title and filtered for language (English/Romance) and period (January 2010-December 2014). Inclusion criteria were: (1) statement to use a case-control design in title, (2) to be a final full-length publication and (3) to have original data in the area of diabetes. Three independent reviewers went through titles, looked for full texts and reviewed them. Discrepancies were settled with a fourth reviewer. Expert epidemiologist advice was requested in case of doubt. case-control mislabelling; addressed predictors: publication year, journal impact factor and journal subject. proportion of mislabelled CC articles and assessment of predictors by multivariate logistic regression analysis. We retrieved 362 articles, 251 of them fulfilling inclusion criteria. The proportion of mislabelled CC studies was 43.8% (confidence interval 95% 37.7-50.0%). Most mislabelled studies had a cross-sectional design (82.7%). Predictors of mislabelling were publication year, journal impact factor and journal area. A relevant subset of studies defined as case-control in the area of diabetes correspond to mislabelled cross-sectional studies. Incorrect labelling misleads readers regarding the interpretation of results and the cause-effect hypothesis. Researchers, reviewers and editors should be aware of and commit to settle this issue.

    A retrospective analysis was performed of 39 patients with locally advanced nasopharyngeal cancer treated with combined chemotherapy and radiation therapy during the last five years at our departments. There were 26 men and 13 women with median age 55 (24-75) years. Histology was squamous cell carcinoma in 6 patients and undifferentiated carcinoma in the remaining 33 patients. Induction chemotherapy consisted of either regimen A (cisplating 100 mg/m{sup 2} day 1, 5-FU 1000 mg/m{sup 2} days 2-6 as continuous infusion, bleomycin 15 mg days 15 and 29 i.m., mitomycin 4 mg/m{sup 2} day 22 and hydroxyurea 1000 mg/m{sup 2} daily days 23-27) or regimen B (carboplatin 300 mg/m{sup 2} day 1, 5-FU 1000 mg/m{sup 2} days 1-5 as continuous infusion and methotrexate 1.2 g/m{sup 2} day 14 with leucovorin rescue). After completion of induction chemotherapy 13 patients (33%) had complete remission (CR) and 19 (49%) partial remission (PR). The CR rate was increased after radiation therapy to 72%. Survival rates were 88% at 12 and 78% at 24 months. Median time to progression was 29.5 months. In conclusion, induction chemotherapy with a platinum-based regimen followed by radiation therapy achieved a high rate of local control. If the treatment also prolongs survival must, however, be studied by randomized trials. (orig.).

    The aim of this study was to determine whether the brain size of young patients with depressive symptoms is smaller than that of healthy controls using magnetic resonance imaging (MRI). We retrospectively evaluated brain size by calculating the ratio of the brain area to that of the skull (the brain-to-skull ratio) on routine MRI scans including the splenium of the corpus callosum obtained from 19 patients <40 years old with depressive symptoms in 2009. The controls were 12 healthy individuals <40 years old who underwent MRI for medical examinations. The mean brain-to-skull ratio of the control group was 0.850±0.022 (range 0.822-0.889), and that of the patient group was 0.819±0.041 (range 0.756-0.878). An unpaired t-test showed a significant difference in the brain-to-skull ratios between these groups (P=0.011). In particular, in 7 of the 19 patients with longer duration of illness and more severe symptoms, the brain-to-skull ratio was 89%-92% of the mean ratio of the control group. The brain size of young patients with depressive symptoms appears to be smaller than that of healthy controls. (author)

    Objective: To analyze the clinical results and prognostic factors of patients with early-stage primary gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: Seventy-seven patients with primary gastric MALT lymphoma treated from 1985 to 2006 were retrospectively analyzed. All patients were pathologically confirmed as MALT lymphoma in stage I, II and II E (by modified Blackedge staging system). Thirty-seven patients had stage I disease, 23 stage II and 17 stage II E . Sixty patients underwent surgical resection and 17 received non-surgical treatment. Survival rates were calculated by the Kaplan-Meier analysis with the Logrank test. Results: With a median follow up of 57 months for the surviving patients (ranging from 1 to 198 months for all patients), the 5-year overall survival rate, disease-free survival rate, loco-regional control rate and distant metastasis free survival rate were 74%, 70%, 76% and 87%, respectively. In univariate analysis, clinical stage was significantly associated with overall survival. Patients with stage I or II disease had a better overall survival than those with stage II E (P=0.01). Tumor size and surgical resection were significantly associated with disease-free survival. Patients with primary tumor 8 cm or less in diameter had better disease-free survival than those with primary tumor more than 8 cm in diameter (P =0.03). Patients who underwent complete resection had better disease-free survival than those who underwent incomplete resection or no surgery (P=0.02). Clinical stage, tumor size and surgical resection were significantly associated with loco-regional control. Patients with stage I or II disease had better loco-regional control than those with stage II E (P=0.03). Patients with primary tumor 8 cm or less in diameter had better loco-regional control than those with primary tumor more than 8 cm in diameter (P=0.01). Patients who underwent complete resection had better loco-regional control than those who underwent

    Syphilitic chorioretinitis should be included in differential diagnosis of any form of ocular inflammation. A significantly higher proportion of human immunodeficiency virus (HIV)-positive patients with ocular syphilis as compared to HIV-negative cases have been reported in published studies. However, the clinical signs and symptoms are more insidious in HIV-negative patients who are easily misdiagnosed. We report a series of cases of ocular syphilis and describe the clinical manifestations and treatment outcomes of syphilitic chorioretinitis in HIV-negative patients in China.This was a retrospective case series study. The clinical records of patients with syphilis chorioretinitis were reviewed. Demographic information and findings of fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), and spectral domain optical coherence tomography (SD-OCT) were analyzed. All patients received the standard treatment. Ophthalmology examination and laboratory evaluation were repeated every 3 months. All changes were recorded. The treatment was considered successful if the patients had no inflammation in both eyes and rapid plasma reagin titer was negative after therapy.The study examined 41 eyes of 28 HIV-negative patients. The main complaints were blurry vision, floaters, and visual field defect. Twenty-seven eyes presented with panuveitis, and all had posterior involvement, including uveitis, vasculitis, chorioretinitis, and optic neuritis. The most common manifestations were uveitis and retinal vasculitis. Disc hyperfluorescence and persistent dark spots were the most common findings on FFA and ICGA. The ill-defined inner segment/outer segment junction was the most frequent manifestation on SD-OCT. Patients were diagnosed with syphilitic uveitis based on positive serological tests. Best-corrected visual acuity (BCVA) was improved in 34 eyes after treatment. Eleven patients were misdiagnosed before serological tests were performed. The delay in treatment

    Full Text Available Introduction. Pre-term premature rupture of membranes (PPROM is one of the leading causes of perinatal morbidity and mortality. This complication is diagnosed in 3% of pregnant women in Kazakhstan, and it is the leading cause of pre-term deliveries. The aim of this study was to determine the outcomes of pregnancies complicated by PPROM in gestation periods between 24 to 32 weeks among three institutions in Kazakhstan.Methods. This is descriptive analysis of 154 cases with PPROM observed between 24 to 32 weeks of gestation at Perinatal Centers #2 and #3 and the National Research Center for Maternal and Child Health, Astana, Kazakhstan. Cases were selected on the basis of retrospective chart review where PPROM diagnosis occurred in 2013. Descriptive statistics were utilized for data analysis.Results. The most frequent complications associated with PPROM were threat of miscarriage (13.6% of cases and chronic placental insufficiency (7.8%. The mean time between PPROM and onset of spontaneous labor was 12.1 ± 2.3 days.  Spontaneous labor within 3 days after PPROM started in patients with an amniotic fluid index of 3.0 ± 0.2 cm. Complications experienced by PPROM women during delivery and early postpartum period included: precipitous labor (6.4%, weakness of labor activity (16.2%, atonic hemorrhage (1.2%, and chorioamnionitis (3.2%. 37.6% of newborns in this study were admitted to the Intensive Care Unit. Their health complications included pneumonia (7.7%, conjunctivitis (1.3%, omphalitis and infectious-toxic shock (3.8%, intraventricular hemorrhage  (7.8%, and respiratory distress (10.3% .Conclusion. Thus, preterm rupture of membranes is associated with preterm delivery and an increase of neonatal morbidity. Therefore, it is necessary to find ways to effectively manage PPROM, including developing new techniques to restore the amniotic fluid volume in women experiencing PPROM during 24 to 32 weeks of gestation.

    Proximal tibia fractures make up 1% of all fractures in adults. The fractures classified as Schatzker V and VI fractures can compromise knee structure and function. They are challenging to treat and often have complications. While plate fixation is the gold standard, the resulting infection rate has led us to favor external hybrid fixation. The aims of this study were to assess the radiographic and functional outcomes along with the complication rate when using this method and to compare them to historical plate fixation data. This was a retrospective study of 40 patients. The complications, quality of reduction, IKS, Lysholm and Rasmussen functional scores at the latest follow-up and factors affecting the functional outcome were evaluated. These parameters were compared to published results from plate fixation studies. The deep infection rate was 2.5%. The union rate was 80%. Satisfactory reduction was obtained in 70% of cases; however, 52% of patients had malunion. The mean IKS score was 73.74, the mean Rasmussen score was 22.85 and the mean Lysholm score was 75.53. Age, reduction at latest follow-up, mechanical axis and anteroposterior laxity had a significant effect on the functional outcome. Despite the malunion rate being higher than other studies, the functional outcomes were nearly identical based on the variables measured. There are several advantages associated with using a hybrid external fixator: shorter operative time, less bleeding, shorter hospital stays and lower infection rate. Hybrid external fixation is a reliable fracture fixation method that leads to satisfactory functional outcomes, while reducing the infection rate and allowing arthroplasty to be performed in the future if needed.

    To assess clinical outcomes including imaging findings on computed tomography (CT), pulmonary function testing (PFT), and glucocorticoid (GC) use in patients with the antisynthetase syndrome (AS) and interstitial lung disease (ILD) treated with rituximab (RTX). We retrospectively identified all patients at 2 institutions with AS-ILD who were treated with RTX. Baseline demographics, PFT, and chest CT were assessed before and after RTX. Two radiologists independently evaluated CT using a standardized scoring system. Twenty-five subjects at the Brigham and Women's Hospital (n = 13) and University of Pittsburgh Medical Center (n = 12) were included. Antisynthetase antibodies were identified in all patients (16 Jo1, 6 PL-12, 3 PL-7). In 21 cases (84%), the principal indication for RTX use was recurrent or progressive ILD, owing to failure of other agents. Comparing pre- and post-RTX pulmonary variables at 12 months, CT score and forced vital capacity were stable or improved in 88% and 79% of subjects, respectively. Total lung capacity (%) increased from 56 ± 13 to 64 ± 13 and GC dose decreased from 18 ± 9 to 12 ± 12 mg/day. Although DLCO (%) declined slightly at 1 year, it increased from 42 ± 17 to 70 ± 20 at 3 years. The most common imaging patterns on CT were nonspecific interstitial pneumonia (NSIP; n = 13) and usual interstitial pneumonia/fibrotic NSIP (n = 5), of which 5 had concurrent elements of cryptogenic organizing pneumonia. Stability or improvement in pulmonary function or severity of ILD on CT was seen in most patients. Use of RTX was well tolerated in the majority of patients. RTX may play a therapeutic role in patients with AS-ILD, and further clinical investigation is warranted.

     This article aimed to describe olecranon fracture in dogs and cats and their stabilization with tension band wiring or plate osteosynthesis, and to evaluate complications associated with each technique.  Medical records of cats and dogs that had been surgically treated for olecranon fractures with either tension band wiring or plate osteosynthesis were retrospectively reviewed. The surgical technique, complications and long-term outcomes were assessed.  Forty-one olecranon fractures were included. Fractures were articular, comminuted and open in 90, 31 and 27% of cases, respectively. Tension band wiring and plate osteosynthesis were performed in 22 and 19 fractures, respectively. Complications occurred more commonly after tension band wiring (74%) compared with plate osteosynthesis (27%) ( p  = 0.002) and these were probably related to it being used in comminuted fractures ( p  = 0.01) or to errors in technique. Minor complications included Kirschner wires migration ( n  = 5), pain ( n  = 3), osteomyelitis ( n  = 3), skin breakdown ( n  = 3) and seroma ( n  = 1). Implant failure requiring further fixation ( n  = 4) was observed only in the tension band wiring group. Other major complications included skin wound debridement and closure ( n  = 1) and chronic lameness requiring implant removal ( n  = 7). Long-term functional outcomes were excellent regardless of the technique used.  Plate osteosynthesis should be performed for olecranon fracture repair if technically feasible.

    The existing information on oral rehabilitations with dental implants in VIH-positive patients is scarce and of poor quality. Moreover, no long-term follow-up studies are available. Hence, the aims of this study were to describe the long-term survival and success rates of dental implants in a group of HIV-positive patients and to identify the most common postoperative complications, including peri-implant diseases. A retrospective case series of HIV-positive subjects treated with dental implants at the School of Dentistry of the University of Barcelona (Spain) was studied. Several clinical parameters were registered, including CD4 cell count, viral load and surgical complications. Additionally, the patients were assessed for implant survival and success rates and for the prevalence of peri-implant diseases. A descriptive statistical analysis of the data was performed. Nine participants (57 implants) were included. The patients' median age was 42 years (IQR=13.5 years). The implant survival and success rates were 98.3% and 68.4%, respectively, with a mean follow-up of 77.5 months (SD=16.1 months). The patient-based prevalence of peri-implant mucositis and peri-implantitis were 22.2% and 44.4% respectively at the last appointment. Patients that attended regular periodontal maintenance visits had significantly less mean bone loss than non-compliant patients (1.3 mm and 3.9 mm respectively). Oral rehabilitation with dental implants in HIV-positive patients seems to provide satisfactory results. In order to reduce the considerably high prevalence of peri-implant diseases, strict maintenance programmes must be implemented.

    The purpose of the study was to describe a unique type of low-energy traumatic pediatric thoracic spinal cord injury without radiographic abnormality (SCIWORA) after a back bend during dance practice and analyze the trauma mechanisms and treatment protocols. This was a retrospective case series from September 2007 to August 2016. The study was conducted at a tertiary medical center in Beijing, China (Xuanwu Hospital, China International Neuroscience Institute [China-INI], Capital Medical University). A total of 12 pediatric patients who had a clear traumatic history after back bend movements and had been diagnosed with thoracic SCIWORA were included. Clinical and imaging data were obtained for each patient. The follow-up data was analyzed. The traumatic mechanisms were investigated by analyzing the patients' medical history, spinal diffusion tensor imaging (DTI) and fiber tractography data. Of the 12 patients, 11 (91.7%) were younger than 8 years old. The mean age of the patients was 6.6 years. All patients had a clear traumatic history of severe thoracic spinal cord injury after performing back bend movements. The mean follow-up time was 36.5 months. During the follow-up period, 1 patient (8.3%) recovered completely, and 11 patients (91.7%) had unfavorable prognoses, including 4 (33.3%) with incomplete recovery and 7 (58.3%) with no change. Two patients underwent spinal DTI, which showed rupture of the nerve fiber bundle in the section of the injury. Back bend movements performed during dance practice may cause pediatric thoracic SCIWORA, particularly in children younger than 8 years old. We suggest that the mechanism of primary injury is the longitudinal distraction of the thoracic spine during back bend movements, which leads to violent distraction of the spinal cord and blunt injury of nerve axons, nerve cells, and small vessels. Spinal DTI may facilitate the diagnosis and prognostic evaluation of SCIWORA.

The local control rate was compared between the two groups using the Kaplan–Meier estimator and the log-rank test. Factors affecting local tumor recurrence were analyzed using multivariate logistic regression analysis. Treatment-related toxicity was evaluated using the Common Terminology Criteria for Adverse Events.Results: The local control rates at 6 months and 1 year were 87% and 65% for the miriplatin plus low-dose epirubicin group, and 61% and 43% for the miriplatin group, respectively. Local tumor control rates were significantly better in the miriplatin plus low-dose epirubicin group than in the miriplatin group (P = 0.038. Multivariate analysis showed that the addition of epirubicin was an independent factor associated with better local tumor control (hazard ratio 0.2, P = 0.001. Overall incidence rates for adverse events were not significantly different between the two groups.Conclusion: Additional usage of low-dose epirubicin for TACE using miriplatin improved local tumor control of hepatocellular carcinoma with adverse effects comparable to those observed with TACE using miriplatin alone.Keywords: combination therapy, local recurrence, liver, embolization, comparative study

    Purpose: To assess the change in diagnostic confidence between first and follow-up dynamic MR examination of the breast (MRM). Methods: The reports of a total of 175 MRM in 77 patients (mean age 50 years; 36-76) with 98 follow-up MRM were analyzed. All examinations were performed as a dynamic study (Gd-DTPA, 0.16 mmol/kg; 6-7 repetitive studies). The change in diagnostic confidence was retrospectively classified as follows: Controlled lesion vanished during follow-up (category I); diagnostic confidence increases during follow-up (II), more likely benign (IIa), more suspicious (IIb); no difference in diagnostic confidence (III). Long-term follow-up over an average of four years was obtained for 57 patients with category IIa/III findings. Results: In 98 follow-up examinations, only two lesions vanished (2%). In 77/98 cases a category IIa lesion was diagnosed, in 11 cases a category IIb lesion. In 8 cases (8%) there was no change in diagnostic confidence during follow-up. Lesions in category IIb underwent biopsy in 10/11 cases, in one case long-term follow-up proved a completely regredient inflammatory change. In 8/11 suspicious findings (IIb) a malignant tumor was detected. The mean time interval between first and follow-up MRM was 8 months for I-IIb lesions, and 4 months for category III lesions. In the longterm follow-up two patients with a category II a lesion developed a carcinoma in a different breast area after four and five years. Conclusion: MRM follow up increases the diagnostic confidence if the time interval is adequate (>4 months). A persistently or increasingly suspicious finding warrants biopsy. (orig.) [de

    Bullous pemphigoid (BP) is the most prevalent autoimmune blistering skin disease in Western countries and in Israel. Initial disease control is achieved in 60-90% of BP patients within 1-4 weeks of corticosteroid therapy. In the remainder of patients, recalcitrant disease is controlled with additional immunosuppressive treatment. We aimed to evaluate the rate of BP patients who needed adjuvant therapy to achieve initial disease control and to identify potential predictors for recalcitrant disease. We conducted a retrospective study of newly diagnosed BP patients who were hospitalized at the Tel Aviv Sourasky Medical Center between the years 2008-2014. We performed statistical analyses to assess the association between clinical factors and failure of initial disease control. Among 114 hospitalized patients with newly diagnosed BP, 1.8% presented with oral mucosa involvement. Seven patients (6.1%) required systemic agents in addition to corticosteroids to achieve disease control. Hypertension (P = 0.048), involvement of the head region (P = 0.042), and metformin treatment (P = 0.02) were significantly more prevalent among patients with recalcitrant disease. The low frequency of recalcitrant BP (6.1%) and the rarity of involvement of the oral mucosa (1.8%) in this study suggest that Israeli BP patients present a milder phenotype compared to similar patients from other geographic areas. Hypertension, head involvement, and metformin therapy were found to be significantly associated with the need for adjuvant therapy to achieve initial control, suggesting that these parameters may serve as predictors of treatment response in BP. © 2017 The International Society of Dermatology.

    To determine the mortality attributable to smoking and years of potential life lost from smoking among people in prison and whether bans on smoking in prison are associated with reductions in smoking related deaths. Analysis of cross sectional survey data with the smoking attributable mortality, morbidity, and economic costs system; population based time series analysis. All state prisons in the United States. Prevalence of smoking from cross sectional survey of inmates in state correctional facilities. Data on state prison tobacco policies from web based searches of state policies and legislation. Deaths and causes of death in US state prisons from the deaths in custody reporting program of the Bureau of Justice Statistics for 2001-11. Smoking attributable mortality and years of potential life lost was assessed from the smoking attributable mortality, morbidity, and economic costs system of the Centers for Disease Control and Prevention. Multivariate Poisson models quantified the association between bans and smoking related cancer, cardiovascular and pulmonary deaths. The most common causes of deaths related to smoking among people in prison were lung cancer, ischemic heart disease, other heart disease, cerebrovascular disease, and chronic airways obstruction. The age adjusted smoking attributable mortality and years of potential life lost rates were 360 and 5149 per 100,000, respectively; these figures are higher than rates in the general US population (248 and 3501, respectively). The number of states with any smoking ban increased from 25 in 2001 to 48 by 2011. In prisons the mortality rate from smoking related causes was lower during years with a ban than during years without a ban (110.4/100,000 v 128.9/100,000). Prisons that implemented smoking bans had a 9% reduction (adjusted incidence rate ratio 0.91, 95% confidence interval 0.88 to 0.95) in smoking related deaths. Bans in place for longer than nine years were associated with reductions in cancer

    Vertebrae, ribs, and spinal cord are anatomically adjacent structures, and their close relationships are clinically important for planning better corrective surgical approach. The objective is to identify the radiographic characteristics in surgical patients with congenital scoliosis (CS) and coexisting split cord malformation (SCM). A total of 266 patients with CS and SCM underwent surgical treatment at our hospital between May 2000 and December 2015 was retrospectively identified. The demographic distribution and radiographic data were collected to investigate the characteristics of spine curve, vertebral, rib, and intraspinal anomalies. According to Pang's classification, all patients were divided into two groups: type I group is defined as two hemicords, each within a separate dural tube separated by a bony or cartilaginous medial spur, while type II group is defined as two hemicords within a single dural tube separated by a nonrigid fibrous septum. There were 104 patients (39.1%) in Type I group and 162 patients (60.9%) in Type II group. SCM was most commonly found in the lower thoracic and lumbar regions. The mean length of the septum in Type I SCM was significantly shorter than Type II SCM (2.7 vs. 5.2 segments). Patients in Type I group had a higher proportion of kyphotic deformity (22.1%). The vertebral deformities were simple in only 16.5% and multiple in 83.5% of 266 cases. Patients in Type I group presented higher prevalence of multiple (90.4%) and extensive (5.1 segments) malformation of vertebrae. In addition, hypertrophic lamina and bulbous spinous processes were more frequent in Type I group (29.7%), even developing into the "volcano-shape" deformities. Rib anomalies occurred in 62.8% of all patients and 46.1% of them were complex anomalies. The overall prevalence of other intraspinal anomalies was 42.9%. The most common coexisting intraspinal anomalies was syringomyelia (30.5%). The current study, with the largest cohort to date, demonstrated that

    Full Text Available Cutaneous leishmaniasis (CL is a major public health concern in Turkey and Sanliurfa represents the most endemic city in Turkey. Although children are most commonly affected by CL, detailed studies of pediatric CL in Turkey are lacking.In this report we retrospectively evaluated clinical and epidemiological data of 8786 pediatric CL cases, and how children respond to antimonial therapy. CL was observed most frequently in children between 6-10 years old. Interestingly this group showed shorter duration of disease and smaller lesions compared to 0-5 year and 11-15 year old groups. Females were more affected in all groups. Lesion localization and types varied among groups, with 0-5 year old presenting head/neck and mucosal lesions, and more often suffered from recidivans type, this could be associated to the longest duration of the disease in this group. Eleven-15 year old group showed fewer lesions in the head/neck but more generalized lesions. Evaluation of treatment response revealed that intra-lesional treatment was preferred over intramuscular treatment. However, 0-5 year old received intramuscular treatment more often than the other groups. Furthermore, the majority of 0-5 year old group which received intra-lesional treatment did not received subsequent intra-lesional cycles, as did children in the range of 6-15 years old.We report an increase in pediatric CL patients within the last four years. Analysis of pediatric CL patients by age revealed significant differences in CL progression. The data suggest that children between 0-5 years old responded better than other groups to intralesional treatment, since they received more often a single cycle of IL treatment, although follow up observation is required since they were more prone to develop recidivans. Eleven-15 year old patients comprise the largest percentage of patients receiving two or three cycles of intralesional treatment, suggesting that this group did not respond efficiently to

    Full Text Available Abstract Background Skin cancers are a major risk associated with albinism and are thought to be a major cause of death in African albinos. The challenges associated with the care of these patients are numerous and need to be addressed. The aim of this study was to outline the pattern and treatment outcome of skin cancers among albinos treated at our centre and to highlight challenges associated with the care of these patients and proffer solutions for improved outcome. Methods This was a retrospective study of all albinos with a histopathological diagnosis of skin cancer seen at Bugando Medical Centre from March 2001 to February 2010. Data collected were analyzed using descriptive statistics. Results A total of 64 patients were studied. The male to female ratio was 1.5:1. The median age of patients was 30 years. The median duration of illness at presentation was 24 months. The commonest reason for late presentation was financial problem. Head and the neck was the most frequent site afflicted in 46(71.8% patients. Squamous cell carcinoma was the most common histopathological type in 75% of cases. Surgical operation was the commonest modality of treatment in 60 (93.8% patients. Radiotherapy was given in 24(37.5% patients. Twenty-seven (42.2% of the patients did not complete their treatment due to lack of funds. Local recurrence following surgical treatment was recorded in 6 (30.0% patients. Only thirty-seven (61.7% patients were available for follow-up at 6–12 months and the remaining patients were lost to follow-up. Conclusions Skin cancers are the most common cancers among albinos in our environment. Albinism and exposure to ultraviolet light appears to be the most important risk factor in the development of these cancers. Late presentation and failure to complete treatment due to financial difficulties and lack of radiotherapy services at our centre are major challenges in the care of these patients.

    The aim of this retrospective analysis was to show the readmission rate of cases with and without early discharge following vaginal or cesarean delivery. After exclusion of cases with pregnancy, delivery and neonatal complications, a total of 14,460 cases who delivered at Zeynep Kamil Women and Children's Health Training and Research Hospital were retrospectively screened from hospital database. Subjects were divided into two groups as Group 1: early discharge (n = 6802) and Group 2: late discharge (n = 7658). Groups were compared in terms of readmission rates and indications for readmission. There were 6802 cases with early discharge whereas the remaining women were discharged after 24 h for vaginal delivery and 48 h following cesarean delivery on regular bases. Among cases with early discharge, 205 (3%) cases readmitted to emergency service with variable indications, while there were 216 (2.8%) readmitted women who were discharged on regular bases. Most common indication for readmission was wound infection in both groups. Neonatal sex distributions were similar between groups (p > .05), where as there was a higher rate of cesarean deliveries in Group 2 (p discharge (p discharges following vaginal or cesarean delivery without any mortality or permanent morbidity and cost analyses revealed 68 Turkish liras lower cost with early discharge.

    Area-level public health interventions can be difficult to evaluate using natural experiments. We describe the use of propensity score matching (PSM) to select control local authority areas (LAU) to evaluate the public health impact of alcohol policies for (1) prospective evaluation of alcohol policies using area-level data, and (2) a novel two-stage quasi case-control design. Ecological. Alcohol-related indicator data (Local Alcohol Profiles for England, PHE Health Profiles and ONS data) were linked at LAU level. Six LAUs (Blackpool, Bradford, Bristol, Ipswich, Islington, and Newcastle-upon-Tyne) as sample intervention or case areas were matched to two control LAUs each using PSM. For the quasi case-control study a second stage was added aimed at obtaining maximum contrast in outcomes based on propensity scores. Matching was evaluated based on average standardized absolute mean differences (ASAM) and variable-specific P-values after matching. The six LAUs were matched to suitable control areas (with ASAM 0.05 indicating good matching) for a prospective evaluation study that sought areas that were similar at baseline in order to assess whether a change in intervention exposure led to a change in the outcome (alcohol related harm). PSM also generated appropriate matches for a quasi case-control study--whereby the contrast in health outcomes between cases and control areas needed to be optimized in order to assess retrospectively whether differences in intervention exposure were associated with the outcome. The use of PSM for area-level alcohol policy evaluation, but also for other public health interventions, will improve the value of these evaluations by objective and quantitative selection of the most appropriate control areas.

    The role of adjuvant radiotherapy (RT) for patients with stage III thymoma after complete resection is not definite. Some authors have advocated postoperative RT after complete tumor resection, but some others suggested observation. In this study, we retrospectively evaluated the effect of postoperative RT on survival as well as tumor control in patients with Masaoka stage III thymoma. Between June 1982 and December 2010, 65 patients who underwent complete resection of stage III thymoma entered the study. Fifty-three patients had adjuvant RT after surgery (S + R) and 12 had surgery only (S alone). Of patients who had adjuvant RT, 28 had three-dimensional conformal RT (3D-CRT)/intensity modulated RT (IMRT) and 25 had conventional RT. A median prescribed dose of 56 Gy (range, 28–60 Gy) was given. The median follow-up time was 50 months (range, 5–360 months). Five- and 10-year overall survival (OS) rates were 91.7% and 71.6%, respectively, for S + R and 81.5% and 65.2% for S alone (P = 0.5), respectively. In the subgroup analysis, patients with 3D-CRT/IMRT showed a trend of improved 5-year OS rate compared with conventional RT (100% vs. 86.9%, P =0.12). Compared with S alone, the 5-year OS rate was significantly improved (100% vs. 81.5%, P = 0.049). Relapses occurred in 15 patients (23.1%). There was a trend of lower crude local recurrence rates for S + R (3.8%) compared with S alone (16.7%) (P = 0.09), whereas the crude regional recurrence rates were similar (P = 0.9). No clear dose–response relationship was found according to prescribed doses. Adjuvant 3D-CRT/IMRT showed potential advantages in improving survival and reducing relapse in patients with stage III thymoma after complete resection, whereas adjuvant RT did not significantly improve survival or reduce recurrence for the cohort as a whole. Doses of ≤ 50 Gy may be effective and could be prescribed for adjuvant RT. To confirm the role of adjuvant 3D-CRT/IMRT in patients who undergo a complete

    Full Text Available Abstract Background Telephone-based care management programmes have been shown to improve health outcomes in some chronic diseases. Birmingham Own Health® is a telephone-based care service (nurse-delivered motivational coaching and support for self-management and lifestyle change for patients with poorly controlled diabetes, delivered in Birmingham, UK. We used a novel method to evaluate its effectiveness in a real-life setting. Methods Retrospective cohort study in the UK. 473 patients aged ≥ 18 years with diabetes enrolled onto Birmingham Own Health® (intervention cohort and with > 90 days follow-up, were each matched by age and sex to up to 50 patients with diabetes registered with the General Practice Research Database (GPRD to create a pool of 21,052 controls (control cohort. Controls were further selected from the main control cohort, matching as close as possible to the cases for baseline test levels, followed by as close as possible length of follow-up (within +/-30 days limits and within +/-90 days baseline test date. The aim was to identify a control group with as similar distribution of prognostic factors to the cases as possible. Effect sizes were computed using linear regression analysis adjusting for age, sex, deprivation quintile, length of follow-up and baseline test levels. Results After adjusting for baseline values and other potential confounders, the intervention showed significant mean reductions among people with diabetes of 0.3% (95%CI 0.1, 0.4% in HbA1c; 3.5 mmHg (1.5, 5.5 in systolic blood pressure, 1.6 mmHg (0.4, 2.7 in diastolic blood pressure and 0.7 unit reduction (0.3, 1.0 in BMI, over a mean follow-up of around 10 months.

    Full Text Available Abstract Background The parasite Toxoplasma gondii infects 30–60% of humans worldwide. Latent toxoplasmosis, i.e., the life-long presence of Toxoplasma cysts in neural and muscular tissues, leads to prolongation of reaction times in infected subjects. It is not known, however, whether the changes observed in the laboratory influence the performance of subjects in real-life situations. Methods The seroprevalence of latent toxoplasmosis in subjects involved in traffic accidents (N = 146 and in the general population living in the same area (N = 446 was compared by a Mantel-Haenszel test for age-stratified data. Correlation between relative risk of traffic accidents and level of anti-Toxoplasma antibody titre was evaluated with the Cochran-Armitage test for trends. Results A higher seroprevalence was found in the traffic accident set than in the general population (Chi2MH = 21.45, p 95= 1.76–4.01 times higher risk of an accident than the toxoplasmosis-negative subjects. The OR significantly increased with level of anti-Toxoplasma antibody titre (p 95 = 1.14–3.03 for the 99 subjects with low antibody titres (8 and 16, higher (OR = 4.78, C.I.95 = 2.39–9.59 for the 37 subjects with moderate titres (32 and 64, and very high (OR = 16.03, C.I.95 = 1.89–135.66 for the 6 subjects with titres higher than 64. Conclusion The subjects with latent toxoplasmosis have significantly increased risk of traffic accidents than the noninfected subjects. Relative risk of traffic accidents decreases with the duration of infection. These results suggest that 'asymptomatic' acquired toxoplasmosis might in fact represent a serious and highly underestimated public health problem, as well as an economic problem.

    We present a series of patients with blunt abdominal trauma who underwent damage control laparotomy (DCL) and introduce a nomogram that we created to predict survival among these patients. This was a retrospective study. From January 2002 to June 2012, 91 patients underwent DCL for hemorrhagic shock. We excluded patients with the following characteristics: a penetrating abdominal injury, age younger than 18 or older than 65 years, a severe or life-threatening brain injury (Abbreviated Injury Scale [AIS] ≥ 4), emergency department (ED) arrival more than 6 hours after injury, pregnancy, end-stage renal disease, or cirrhosis. In addition, we excluded patients who underwent DCL after ICU admission or later in the course of hospitalization. The overall mortality rate was 61.5%: 35 patients survived and 56 died. We identified independent survival predictors, which included a preoperative Glasgow Coma Scale (GCS) score blunt abdominal trauma with exsanguination. The nomogram presented here may provide ED physicians and trauma surgeons with a tool for early stratification and risk evaluation in critical, exsanguinating patients.

    Gastric gastrointestinal stromal tumors (GISTs) have a highly variable clinical course, and recurrent disease sometimes develops despite curative surgery. This study was undertaken to investigate the surgical role in treating gastric GISTs and evaluate the clinicopathological features of a large series of patients who underwent curative resection for gastric GISTs to clarify which features were independent prognostic factors. The clinicopathological data of 406 patients with gastric GISTs who underwent curative resection at 4 university hospitals in Daegu, South Korea, from March 1998 to March 2012 were reviewed. All cases were confirmed as gastric GISTs by immunohistochemical staining, in which CD117 or CD34 was positive. Clinical follow-up was performed periodically, and disease-free survival rates were retrospectively investigated using the medical records. The mean follow-up period was 42.9 months (range: 2-166). There were 11 recurrent patients (2.7%). Due to the small number of recurrences, age, sex and location were controlled using propensity score matching before performing any statistical analysis. Tumor size, mitotic count, NIH classification, and cellularity were judged to be independent prognostic factors for recurrence by univariate analysis. In a multivariate analysis, tumor size and mitotic count were significantly and independently related to recurrence, and tumor size was determined to be the most important prognostic factor for recurrence after curative resection (hazard ratio: 1.204; p < 0.01). The results of this multicenter study demonstrate that disease-free survival rates are good. Tumor size was disclosed as the most important factor for recurrence in gastric GIST patients who underwent radical resection. 2015 S. Karger AG, Basel.

    Mammography screening reduces breast cancer mortality by up to 32%. However, some recent studies have questioned the impact of non-palpable breast cancer detection on mortality reduction. The aim of this study was to analyse the clinicopathological and long-term follow-up data of early stage screened and symptomatic breast cancer patients. The institutional prospectively led database was systematically analysed for breast cancer cases diagnosed via the mammography screening program from 2002 to 2009. As a control group, symptomatic early stage breast cancer patients were collected randomly from the same database and matched for age and follow-up period. All medical records were reviewed retrospectively. Data from 298 breast cancer patients were collected from 47,718 mammography screenings. In addition, 331 symptomatic breast cancer patients were randomly selected. The screened group presented a significantly lower median tumour size (P screened group (P screened group did not exhibit better overall (P = 0.717) or disease-free survival (P = 0.081) compared to the symptomatic group. Our results do not suggest that mammography screening does not reduce breast cancer mortality but the mammography screening did not bring any significant improvement in patient overall or disease-free survival for the early stage breast cancer patients compared to the symptomatic group. The drawback of symptomatic early stage tumours compared to non-palpable tumours could be equalized by modern multimodality oncology treatments.

    are interchangeable with the experience for population controls. Patient controls may even be preferable from population controls under certain conditions. In this study we examine if colon cancer patients can serve as surrogates for proper population controls in case-control studies of occupational risk factors...... about occupational, medical and life style conditions. RESULTS: No statistical significant difference for educational level, medical history or smoking status was seen between the two control groups. There was evidence of a higher alcohol intake, less frequent work as a farmer and less exposure...... to pesticides among colon cancer controls. CONCLUSIONS: Use of colon cancer controls may provide valid exposure estimates in studies of many occupational risk factors for cancer, but not for studies on exposure related to farming....

    The numerous cohort of Chernobyl liquidators is a very attractive subject for epidemiological follow up due to high levels of exposure, age-gender distribution and availability of patients for medical examination. However, dosimetric information related to this population is incomplete, in many cases the quality of available dose records is doubtful and uncertainties of all dose values are not determined. Naive attempts to evaluate average doses on the basis of such factors as 'distance from the reactor' obviously fail due to large variation of tasks and workplace contamination. Therefore, prior to any sensible consideration of liquidators as a subject of epidemiological study, their doses should be evaluated (reevaluated) using the methods of retrospective dosimetry. Retrospective dosimetry in general got significant development over the last decade. However, most of the retrospective dosimetry techniques are time consuming, expensive and possess sensitivity threshold. Therefore, application of retrospective dosimetry for the needs of epidemiological follow up studies requires development of certain strategy. This strategy depends, of coarse, on the epidemiological design of the study, availability of resources and dosimetric information related to the time of clean up. One of the strategies of application of retrospective dosimetry may be demonstrated on the example of a cohort study with occasional nested case control consideration. In this case, the tools are needed for validation of existing dose records (of not always known quality), screening of the study cohort with express dosimetric method called to determine possible dose ranges, and 'state-of-the-art' assessment of individual doses for selected subjects (cases and controls). Verification of dose records involves analysis of the statistical regularities of dose distributions and detection of possible extraneous admixtures (presumably falsified dose records).

This study aimed to determine the prevalence of childhood trauma in patients in the UK Early Intervention Service based on a case note review.Methods: This is a retrospective case note study of 296 patients in an UK Early Intervention Service. Trauma history obtained on service entry was reviewed and trauma experienced categorized. Results were analyzed using crosstab and frequency analysis.Results: The mean age of the sample was 24 years, 70% were male, 66% were White, and 23% Asian (ethnicity not documented in 11% of the sample. Approximately 60% of patients reported childhood trauma, 21% reported no childhood trauma, and data were not recorded for the remaining 19%. Among those reporting trauma, the prevalence of most frequently reported traumas were: severe or repeated disruption (21%, parental mental illness (19%, bullying (18%, absence of a parent (13%, and ‘other’ trauma (24% – the majority of which were victimization events. Sixty-six percent of those reporting trauma had experienced multiple forms of trauma.Conclusion: A high prevalence of childhood trauma (particularly trauma related to the home environment or family unit was reported. This is consistent with other studies reporting on trauma and psychosis. The main weakness of the study is a lack of a control group reporting experience of childhood trauma in those without psychosis. Guidelines recommend that all patients with

    This study presents the results of a retrospective study evaluating the contribution of Italian nurses to the public debate on the Englaro case, analysing the articles published by two major daily newspapers during a precise period. The data collected testify to the intensity of the debate that involved the whole nation in which many diverse social and professional categories took part. The nursing category was principally represented by the Sisters of Mercy who, at the insistence of the media, gave their own opinion although their role in this context was more as personal assistants to Eluana Englaro rather than representatives of a professional category expressing a bioethical opinion.

    To examine the factors associated with blindness from primary open-angle glaucoma (POAG) among black and white patients at our institution. For this retrospective, case-control study, patients legally blind from POAG ("cases") were matched on age, race, and gender with non-blind POAG patients ("controls"). Thirty-seven black case-control pairs and 19 white case-control pairs were included in this study. Clinical variables were compared at initial presentation and over the course of follow-up. Black case-control pairs and white case-control pairs had similar characteristics at presentation, including cup-to-disc ratio and number of glaucoma medications. However, over the course of follow-up, black cases underwent significantly more glaucoma surgeries than matched controls (2.4 versus 1.2, p =0.001), whereas white cases and controls had no significant difference in glaucoma operations (0.9 versus 0.6, p =0.139). Our analysis found that glaucoma surgery is associated with blindness in black patients (odds ratio [OR] 1.6, 95% CI 1.1-2.2) but not in white patients (OR 1.5, 95% CI 0.7-3.2). Black and white case-control pairs with POAG shared similar risk factors for blindness at presentation. However, over the follow-up period, black cases required significantly more glaucoma surgeries compared to black controls, whereas there was no significant difference in surgery between white cases and controls. There was no difference in medication changes in either case-control set.

    Streptococcus suis is a zoonotic cause of severe meningitis and sepsis in humans. We aimed to assess the long-term outcomes in patients who survived S. suis infection, in particular the progress and impact of vestibulocochlear sequelae. This case-control study evaluated outcomes of S. suis infection at discharge and 3 and 9 months post-discharge for 47 prospectively enrolled cases and at 11-34 months for 31 retrospectively enrolled cases. Outcomes in patients were compared to 270 controls matched for age, sex and residency. The prevalence ratio (PR) of moderate-to-complete hearing loss was 5.0(95%CI 3.6-7.1) in cases at discharge, 3.7(2.5-5.4) at 3 months, 3.2(2.2-4.7) at 9 months, and 3.1(2.1-4.4) in retrospective cases compared to controls. Hearing improvement occurred mostly within the first 3 months with a change in hearing level of 11.1%(95%CI 7.0-15.1%) compared to discharge. The PR of vestibular dysfunction was 2.4(95%CI 1.7-3.3) at discharge, 2.2(1.4-3.1) at 3 months, 1.8(1.1-2.5) at 9 months, and 1.8(1.1-2.6) for retrospective cases compared to controls. Cases also indicated more problems with mobility, self-care and usual activities. Both hearing and vestibular impairment were common and persist in cases. Appropriate patient management strategies are needed to reduce the incidence and impact of these sequelae. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Case-Control study design is a type of observational study. In this design, participants are selected for the study based on their outcome status. Thus, some participants have the outcome of interest (referred to as cases), whereas others do not have the outcome of interest (referred to as controls). The investigator then assesses the exposure in both these groups. The investigator should define the cases as specifically as possible. Sometimes, definition of a disease may be based on multiple criteria; thus, all these points should be explicitly st
