    Leptospirosis is an emerging zoonosis attributed to multiple reservoirs. Climatic conditions influence the transmission of pathogenic leptospires, which require warm and humid conditions for survival. The influence of seasonality in human and animal leptospirosis in the subtropical region of Brazil remains poorly understood. We performed a retrospective study to describe the patterns of human and animal exposure to leptospirosis and their association with precipitation events in Southern Brazil. Rainfall data were obtained from satellite images. Serum samples were tested using the microscopic agglutination test (MAT); samples with titer ≥ 100 were defined as seroreactive. Linear regression and Pearson's correlation were performed to assess whether there is a relationship between these variables. We found that precipitation events were not significantly associated with the exposure to leptospirosis in humans or animal species, except for dogs. The interspecies analysis revealed an association between canine and human exposure to leptospirosis. Leptospira kirschneri serovar Butembo (serogroup Autumnalis) presented the highest seroreactivity in humans. This study provides valuable insights in human and animal leptospirosis in Southern Brazil. These insights will be essential to design intervention measures directed to reduce disease dissemination.

    Full Text Available The rising prevalence of diabetes mellitus (DM worldwide, especially in developing countries, and the persistence of tuberculosis (TB as a major public health issue in these same regions, emphasize the importance of investigating this association. Here, we compared the clinical profile and disease outcomes of TB patients with or without coincident DM in a TB reference center in Brazil.We performed a retrospective analysis of a TB patient cohort (treatment naïve of 408 individuals recruited at a TB primary care center in Brazil between 2004 and 2010. Data on diagnosis of TB and DM were used to define the groups. The study groups were compared with regard to TB disease presentation at diagnosis as well as to clinical outcomes such as cure and mortality rates upon anti-tuberculosis therapy (ATT initiation. A composite score utilizing clinical, radiological and microbiological parameters was used to compare TB severity between the groups.DM patients were older than non-diabetic TB patients. In addition, diabetic individuals more frequently presented with cough, night sweats, hemoptysis and malaise than those without DM. The overall pattern of lung lesions assessed by chest radiographic examination was similar between the groups. Compared to non-diabetic patients, those with TB-diabetes exhibited positive acid-fast bacilli in sputum samples more frequently at diagnosis and at 30 days after ATT initiation. Notably, higher values of the TB severity score were significantly associated with TB-diabetes comorbidity after adjustment for confounding factors. Moreover, during ATT, diabetic patients required more frequent transfers to TB reference hospitals for complex clinical management. Nevertheless, overall mortality and cure rates were indistinguishable between the study groups.These findings reinforce the idea that diabetes negatively impacts pulmonary TB severity. Our study argues for the systematic screening for DM in TB reference centers in endemic

    Odontogenic tumors (OTs) are lesions that develop exclusively on maxillary bones, and form a heterogeneous group. They vary from hamartomatous lesions to benign and malign tumors. Although they are rarely observed in dentistry clinics, it is extremely important for the dentist to be aware of them. The aim of this study was to investigate the incidence of odontogenic tumors diagnosed in the population of Florianópolis, Santa Catarina, Brazil. Cases of odontogenic tumors were selected from the anatomopathological diagnostic services at Federal University of Santa Catarina from 1998 to 2011. Clinical data on these cases were collected from biopsy reports and patient files. Seventy-eight cases of odontogenic tumors were surveyed. Of these diagnoses, 51% were keratocystic odontogenic tumors (KCOTs); the remaining cases were mainly ameloblastomas and odontomas. The most frequently observed lesion in this retrospective study was KCOT (more than half of cases). Thus, this study shows that modifying the classification of the OTs altered the frequency of the lesions, possibly making KCOT the most common lesion observed in diagnostic services worldwide.

    Full Text Available A retrospective serologic study was carried out in Fortaleza, State of Ceará, Brazil, in order to detect the dengue virus activity before recognizing the epidemic of 1994. Mac-Elisa was performed by using a mixture of specific DEN-1 and DEN-2 antigens on serum samples from the Emilio Ribas Laboratory collection. Samples were obtained from 1,224 patients with exanthematic febrile disease and negative serological results for rubella. All specimens were taken during November 1993 to May 1994. The results confirmed dengue infections in Fortaleza by November 1993, approximately six months before the beginning of the epidemic, proving how misleading diagnosis of dengue infection are still troublesome, in spite of the strong dengue activity in Ceará. The authors stress the urgent necessity to implement the active surveillance system in order to prevent another extensive dengue fever epidemics in the state. Epidemiological background of the dengue activity in the State of Ceará is also described.

    This study investigated postmarketing safety events (PMSEs) for new drugs approved in Brazil and evaluated whether a range of drug characteristics influenced the time between approval and the first PMSE. This retrospective study included new drugs registered between 2003 and 2013 by the National Health Surveillance Agency (ANVISA), which is responsible for medicines approval in Brazil. PMSEs were defined as any drug safety alert or drug withdrawal from the market. The existence of risk evaluation and mitigation strategies (REMS) by the US Food and Drug Administration (FDA) and Brazil were recorded. A Kaplan-Meier survival curve of the period between the date of ANVISA registration and the PMSE was calculated. We found a statistically significant difference between the time to PMSE for drugs with an FDA REMS compared with those without a REMS, with a log rank value (Mantel Cox) of 0.002. There was no association between the time to PMSE and the other drug characteristics investigated. This study demonstrated that the frequency of PMSEs for new drugs approved by ANVISA was statistically associated with the existence of an FDA REMS. The time between approval and first PMSE was shorter for drugs with an FDA REMS, and this finding may contribute to improved awareness of the risk/benefit balance required to ensure continued safe and effective use of new drugs. © 2016, The American College of Clinical Pharmacology.

    Geographical Information Systems (GIS) is frequently used in the control of animal diseases. In Brazil, the most impacting economical loss in the beef supply chain is bovine cysticercosis. This study focused on assessing the prevalence and geospatial distribution of bovine cysticercosis in 19 Brazilian states. To this, we gathered data from 146,346,244 bovines slaughtered between the years of 2010 and 2015. The observed prevalence was 0.62% (C.I. 0.62-0.63). In total, 30.86% cysticerci were viable, while 69.14% were unviable. Bovine cysticercosis cases had a significant decrease (p<0.05) during this period. The states of Paraná (2.01%; C.I. 2.00-2.02), Santa Catarina (1.96%; C.I. 1.93-2.00), São Paulo (1.77%; C.I. 1.76-1.77), Rio Grande do Sul (1.63%; C.I. 1.60-1.63) and Mato Grosso do Sul (0.80%; C.I. 0.80-0.80) had the highest prevalence values. In some states a significant (p<0.05) decreasing trend was detected in the prevalence. In conclusion, Taenia-saginata-cysticercosis remains endemic in Brazil and interventions are necessary to maintain Brazilian beef competitive in the international food market and improve food safety to population.

    Few data are available about progressive multifocal leukoencephalopathy (PML) in patients with acquired immunodeficiency syndrome (AIDS) from Brazil. The objectives of this study were to describe the main features of patients with PML and estimate its frequency among AIDS patients with central nervous system (CNS) opportunistic diseases admitted to the Instituto de Infectologia Emílio Ribas, São Paulo, Brazil, from April 2003 to April 2004. A retrospective and descriptive study was performed. Twelve (6%) cases of PML were identified among 219 patients with neurological diseases. The median age of patients with PML was 36 years and nine (75%) were men. Nine (75%) patients were not on antiretroviral therapy at admission. The most common clinical manifestations were: focal weakness (75%), speech disturbances (58%), visual disturbances (42%), cognitive dysfunction (42%), and impaired coordination (42%). The median CD4+ T-cell count was 45 cells/microL. Eight (67%) of 12 patients were laboratory-confirmed with PML and four (33%) were possible cases. Eleven (92%) presented classic PML and only one case had immune reconstitution inflammatory syndrome (IRIS)-related PML. In four (33%) patients, PML was the first AIDS-defining illness. During hospitalization, three patients (25%) died as a result of nosocomial pneumonia and nine (75%) were discharged to home. Cases of PML were only exceeded by cases of cerebral toxoplasmosis, cryptococcal meningoencephalitis, and CNS tuberculosis, the three more frequent neurologic opportunistic infections in Brazil. The results of this study suggest that PML is not an uncommon HIV-related neurologic disorder in a referral center in Brazil.

    Full Text Available There is considerable data to support a central role for human papillomavirus (HPV in the etiology of cervical cancer. More than a 100 HPV types have been described, and 40 have been isolated from benign and malignant genital lesions. Consequently, there is strong motivation to evaluate HPV testing for cervical cancer screening. Few studies concerning the natural history of HPV infection have been conducted in the state of Rio de Janeiro. We determined the prevalence of HPV types in female genital lesions by using Hybrid Capture Assay (HCA and we retrospectively analyzed the course of HPV infection. Our sample included 788 women attended at Laboratórios Sérgio Franco. The average age of the participants was 29.6 years. HPV prevalence and cytological diagnosis were determined. The overall prevalence of HPV DNA in the study group was 50.1% (395/788, ranging from 25% (NORMAL to 100% in high-grade intraepithelial lesions (HSIL. High risk HPV was found in 12% inflammatory, 58.3% HPV, 63.2% LSIL and 100% HSIL. A retrospective analysis of 78 patients showed that 22 presented persistent lesions, 2 had progressive lesions, 4 had regressive lesions, 13 showed latent infections, 18 were transiently infected and 19 were submitted to curative treatment. No cases of cancer were registered in this population, which can afford private medical care and regular follow-up exams. We suggest that HCA be used in specific cases involving persistent and recurrent lesions.

    Full Text Available ABSTRACTPurpose:Epidemiological analysis of limbal transplantation surgeries performed in the Ophthalmologic Hospital of Sorocaba.Methods:Retrospective medical records review of 30 patients who underwent limbal stem cell transplants between January 2003 and March 2008. Cases involving conjunctival limbal autograft were classified as group I, and those involving conjunctival limbal allograft as group II.Results:Two patients were excluded due to incomplete data during postoperative follow-up. Of the total sample of 28 patients, 53.6% constituted group I, whereas 46.4% were included in group II. Males were predominant (67.9%, and right eyes were the most prevalent (67.9%. The mean age was 40.3 years. Unilateral cases accounted for 60.7%. The most frequent pathology causing limbal system failure was chemical burns (53%. The mean length of time from diagnosis to surgery was 11.18 years. The limbal graft and amniotic membrane were associated in 75% of all cases, and tarsorrhaphy in 57.1%. The average follow-up period was 24.84 months. The uncorrected visual acuity improved in 38% of the cases, was unchanged in 28.5%, and deteriorated in 33.3%. There was no persistent epithelial defect in 75% of the patients. The conjunctivalization rate was similar between the groups (53.3% and 58.3%, respectively. The transparency improved in only 38.4% of the cases, and 28.5% of the surgeries performed were successful. The most prevalent complication was persistent epithelial defect, which occurred in 25% of the patients, followed by corneal melting in 14.2%. Other complications observed included infectious ulcers, limbal graft necrosis or ischemia, perforation, and descemetocele.Conclusion:Chemical burns remain the main cause of limbal stem cell deficiency. In these cases, limbal transplantation is the standard procedure to restore the ocular surface even though the success rate is low.

    Dengue is a major public health challenge in Brazil. We assessed the relationship between symptomatic dengue infection during pregnancy and adverse birth outcomes in the country between 2007 and 2013. We did a retrospective observational cohort study using information reported in the Brazilian national reportable disease information system (SINAN) and the livebirth information system (SINASC) databases. We probabilistically linked confirmed dengue-positive and dengue-negative pregnancies with live childbirths using Fine-Grained Record Integration and Linkage (FRIL) software. We also included an external reference population of randomly selected newborn babies. Pregnancy was adopted as the unit of analysis. We assessed the relationship between symptomatic dengue infection during pregnancy and adverse birth outcomes, using multivariable logistic regression adjusted for relevant covariates. 3898 dengue-positive pregnant women, 3165 dengue-negative women, and 3898 newborn babies from the reference population were included in the analysis. Preterm birth occurred in 322 (8·4%) of 3821 cases in the dengue-positive group versus 324 (10·4%) of 3101 in the dengue-negative group (unadjusted analysis: relative risk [RR] 0·81, 95% CI 0·70-0·93; adjusted analysis: odds ratio [OR] 1·26, 95% CI 1·06-1·49, p=0·006) and 349 (9·1%) of 3818 in the reference population (RR 0·92, 0·80-1·07; OR 0·98, 0·83-1·16, p=0·84). The prevalence of low birthweight (dengue-positive women and dengue-negative women (8·3% [322 of 3897] vs 9·8% [310 of 3163]; OR 1·17, 95% CI 0·99-1·39, p=0·07), and in the reference population (8·3% vs 9·0% [350 of 3895]; OR 1·00, 0·85-1·17, p=0·97). The prevalence of malformations did not differ significantly for the dengue-positive group (27 [0·7%] of 3789) versus the dengue-negative group (27 [0·9%] of 3059, p=0·51) or versus the reference population (32 [0·9%] of 3738, p=0·56). In the adjusted analysis, the risk of preterm birth

    The aim of the study was to look back on the course of action involving measures of tuberculosis control in Brazil since the end of the 19th century, covering the history of social struggles and pointing out institutions and people that have dedicated themselves to looking for solutions to these issues. The Brazilian response to tuberculosis started in society with the Ligas Contra a Tuberculose (Leagues Against Tuberculosis), promoting scientific advances, such as the BCG vaccination, which begun in 1927. From the public power, the Inspetoria de Profilaxia da TB (TB Prophylaxis Inspection Service - 1920), the Serviço Nacional de Tuberculose (National Service of Tuberculosis - 1940), and the Campanha Nacional Contra a Tuberculose (National Campaign Against Tuberculosis - 1946), coordinated national policies such as chemotherapy, beginning with the discovery of streptomycin in 1944. The emergence of bacterial resistance led to the development of several therapeutic schemes. The Scheme 1 (rifampycin, hydrazide and pyrazinamid), which was the main one in 1979 and is still used nowadays, had a great epidemiological effect. The WHO declared TB a public health emergency in 1993. In response, Brazil developed some strategies; the first one was the Plano Emergencial para Controle da Tuberculose (Emergency Plan for Tuberculosis Control - 1994), prioritizing 230 municipalities. The current prospects are an effective municipalization of actions and their greater integration with the Programas de Agentes Comunitários e Saúde da Família (Humanitarian Agents and Family Health Programs).

    Full Text Available SUMMARY Background: Tuberculosis is a serious health problem in Brazil so that the knowledge on the aspects of cutaneous tuberculosis is medically important. Objective: To assess the characteristics of patients with cutaneous tuberculosis treated at the Cassiano Antonio Moraes University Hospital, located in the city of Vitória, State of Espírito Santo, Brazil. Methods: This is a retrospective, descriptive, observational and cross-sectional study using the medical records of 29 patients with cutaneous tuberculosis treated at the Dermatology and Pulmonology services of the hospital from 1986 to 2011. The inclusion criterion was the confirmation of cutaneous tuberculosis taking into account clinical, epidemiological, immunological, and bacteriological findings, as well as the response to specific treatment. Results: Of the 29 studied patients; 18 (62% were women with average age of 37 years; the predominant clinical condition was erythema induratum of Bazin in 12 (41.4% cases; and the cutaneous lesions were in the lower limbs in 19 (65.8% patients. Extra-cutaneous involvement occurred in eight (27.6% cases. The tuberculin tests were positive in 15 (79% individuals and the assessment of the infectious agent was negative in most of the investigated cases. Conclusion: The study found a low frequency (0.44% of cutaneous tuberculosis in an endemic area of tuberculosis. There was a predominance of infection in women aged thirty to forty years. Erythema induratum was the most common clinical condition, affecting mainly the lower limbs, in contrast to other Brazilian studies that found scrofuloderma as the most common manifestation, predominating in the cervical region of male children and adolescents.

    Full Text Available Cutaneous food allergy is an adverse immunological response, triggered by antigenic dietary components that may escape the digestion process and are absorbed intact through the gastrointestinal mucosa. In Brazil, there are only a few reports on cutaneous food allergy and antigenicity of food components used in pet food production. Thus, the aim of this report was to assess and describe data from medical records of canine patients diagnosed with cutaneous food allergy at a Veterinary Teaching Hospital from Jaboticabal, SP, Brazil, in order to evaluate epidemiological and clinical aspects related to this skin problem. From 2007 to 2012, 29 dogs received the diagnosis of cutaneous food allergy after an eight-week hypoallergenic elimination trial. Among them, purebred dogs were more frequent, as well as females, and their mean age was 50.4 months old. Pruritus was reported in all cases, especially in interdigital areas. In order to establish the diagnosis, most patients received home-cooked elimination diet, based on potato and lamb in approximately 80% of the cases. Besides, it was highlighted the importance of the hypoallergenic elimination diet being rigorously followed by dogs' owners, aiming the adequate control of the clinical signs related to cutaneous food allergy.

    Full Text Available CONTEXT AND OBJECTIVE: Being born heavier than 4 kg is associated with current overweight and obesity over the long term. The objective here was to ascertain whether birth weight was related to overweight or obese status, among 7 to 14-year-old schoolchildren, taking into consideration the possible interactions between socioeconomic factors and other biological variables.DESIGN AND SETTING: Retrospective cohort study on a probabilistic sample of 2,696 children and adolescents living in Florianópolis, Santa Catarina, Brazil.METHODS: The following data were collected: anthropometric (student's weight, height and age; and parents' weight and height, socioeconomic (family income, number of people in house and parental schooling level, birth weight and gestational age. Overweight and obesity were classified using percentiles of body mass index and triceps and subscapular skinfolds. The outcome variables were overweight and obesity and the main explanatory variables were birth weight and birth weight according to gestational age. The control variables were the parents' nutritional status, their schooling level and theper capita family income. Poisson multivariate regressions were carried out.RESULTS: Higher prevalence of high birth weight was observed among overweight male adolescents (PR = 1.14; 95% CI = 1.02-1.27; P = 0.03, but this was not observed among obese male adolescents. Low birth weight and being born small for gestational age were also not associated with the outcomes. Among overweight and obese children, birth weight was not significantly different from that of normal-weight children.CONCLUSION: No significant association between birth weight and obesity was observed. However, there was a weak but significant association between high birth weight and overweight, among male adolescents.

    Maternal mortality remains a major public health issue worldwide, with persistent high rates prevailing principally in underdeveloped countries. The objective of this study was to determine the risk factors for severe maternal morbidity and near miss (SMM/NM) in pregnant and postpartum women at the maternity ward of the Dom Malan Hospital, Petrolina, in northeastern Brazil. A retrospective, cohort study was conducted to evaluate the sociodemographic and obstetric characteristics of the women. Patients who remained hospitalized at the end of the study period were excluded. Risk ratios (RR) and their respective 95% confidence intervals (95% CI) were calculated as a measure of relative risk. Hierarchical multiple logistic regression was also performed. Two-tailed p-values were used for all the tests and the significance level adopted was 5%. A total of 2,291 pregnant or postpartum women receiving care between May and August, 2011 were included. The frequencies of severe maternal morbidity and near miss were 17.5% and 1.0%, respectively. Following multivariate analysis, the factors that remained significantly associated with an increased risk of SMM/NM were a Cesarean section in the current pregnancy (OR: 2.6; 95% CI: 2.0 - 3.3), clinical comorbidities (OR: 3.4; 95% CI: 2.5 - 4.4), having attended fewer than six prenatal visits (OR: 1.1; 95% CI: 1.01 - 1.69) and the presence of the third delay (i.e. delay in receiving care at the health facility) (OR: 13.3; 95% CI: 6.7 - 26.4). The risk of SMM/NM was greater in women who had been submitted to a Cesarean section in the current pregnancy, in the presence of clinical comorbidities, fewer prenatal visits and when the third delay was present. All these factors could be minimized by initiating a broad debate on healthcare policies, introducing preventive measures and improving the training of the professionals and services providing obstetric care.

    To determine if the fortification of wheat and maize flours with iron and folic acid - which became mandatory in Brazil from June 2004 - is effective in the prevention of neural tube defects. Using data from national information systems on births in central, south-eastern and southern Brazil, we determined the prevalence of neural tube defects among live births and stillbirths in a pre-fortification period - i.e. 2001-2004 - and in a post-fortification period - i.e. 2005-2014. We distinguished between anencephaly, encephalocele, meningocele, myelomeningocele and other forms of spina bifida. There were 8554 neural tube defects for 17,925,729 live births notified between 2001 and 2014. For the same period, 2673 neural tube defects were reported for 194,858 stillbirths. The overall prevalence of neural tube defects fell from 0.79 per 1000 pre-fortification to 0.55 per 1000 post-fortification (prevalence ratio, PR: 1.43; 95% confidence interval, CI: 1.38-1.50). For stillbirths, prevalence fell from 17.74 per 1000 stillbirths pre-fortification to 11.70 per 1000 stillbirths post-fortification. The corresponding values among live births were 0.57 and 0.44, respectively. The introduction of the mandatory fortification of flour with iron and folic acid in Brazil was followed by a significant reduction in the prevalence of neural tube defects in our study area.

    Antiretroviral therapy (ART) agents potentially associated with adverse metabolic profiles are commonly used in low- and middle-income countries. We assessed risk factors for cardiovascular disease (CVD)-related morbidity and mortality in a cohort of HIV-infected, ART-treated adults in Rio de Janeiro, Brazil. Hospital records and mortality data between 2000-2010 were examined for incident CVD-related ICD-10 and Coding of Death in HIV diagnoses among adults ≥18 years old on ART, enrolled in an observational cohort. Poisson regression models assessed associations between demographic and clinical characteristics and ART agent or class on CVD event risk. Of 2960 eligible persons, 109 had a CVD event (89 hospitalizations, 20 deaths). Participants were 65 % male, 54 % white, and had median age of 37 and 4.6 years on ART. The median nadir CD4(+) T lymphocyte count was 149 cells/mm(3). The virologic suppression rate at the end of study follow-up was 60 %. In multivariable models, detectable HIV-1 RNA prior to the event, prior CVD, less time on ART, age ≥40 at study baseline, nadir CD4(+) T lymphocyte count ≤50 cells/mm(3), non-white race, male gender, and a history of hypertension were significantly associated with CVD event incidence (p ART on CVD risk and the need for metabolically-neutral first- and second-line ART in resource-limited settings.

    Full Text Available The objectives of this study were to estimate the incidence and describe the pattern and severity of training injuries in taekwondo, and to compare pattern and severity of training injuries with competition injuries. One hundred and fifty-two active Australian amateur taekwondo athletes, aged 12 years or over, completed an online survey comprising questions on training exposure and injury history over the preceding 12 months. The main outcome measures were: overall injury incidence rate per athlete-year; training injury incidence rate per athlete-year, per 1000 athlete-training-sessions, and per 1000 athlete-hours of training; injury severity; and injury proportions by anatomical region and by type of injury. Injury incidence rates were calculated with 95% confidence intervals using standard methods, while injury proportions were compared using Fisher’s exact test. The vast majority (81.5% of taekwondo injuries in an average athlete-year occurred during training. The training injury incidence rate was estimated to be 1.6 (95% CI: 1.4, 1.9 per athlete-year, 11.8 (95% CI: 10.4, 13.4 per 1000 athlete-training-sessions, and 7.0 (95% CI: 6.1, 7.9 per 1000 athlete-hours of training. Among athletes with five or fewer injuries, the severity and injury pattern of training injuries were, by and large, the same as for competition injuries. Approximately sixty percent (60.3% of training injuries required treatment by a health professional. Considering the burden of training injuries exceeds that of competition injuries, taekwondo governing bodies and stakeholders are encouraged to devote more efforts towards the identification of risk factors for, and prevention of, training injuries in the sport of taekwondo.

    Symptomatic forms of toxoplasmosis are a serious public health problem and occur in around 10-20% of the infected people. Aiming to improve the molecular diagnosis of symptomatic toxoplasmosis in Brazilian patients, this study evaluated the performance of real time PCR testing two primer sets (B1 and REP-529) in detecting Toxoplasma gondii DNA. The methodology was assayed in 807 clinical samples with known clinical diagnosis, ELISA, and conventional PCR results in a 9-year period. All samples were from patients with clinical suspicion of several features of toxoplasmosis. According to the minimum detection limit curve (in CT), REP-529 had greater sensitivity to detect T. gondii DNA than B1. Both primer sets were retrospectively evaluated using 515 DNA from different clinical samples. The 122 patients without toxoplasmosis provided high specificity (REP-529, 99.2% and B1, 100%). From the 393 samples with positive ELISA, 146 had clinical diagnosis of toxoplasmosis and positive conventional PCR. REP-529 and B1 sensitivities were 95.9% and 83.6%, respectively. Comparison of REP-529 and B1 performances was further analyzed prospectively in 292 samples. Thus, from a total of 807 DNA analyzed, 217 (26.89%) had positive PCR with, at least one primer set and symptomatic toxoplasmosis confirmed by clinical diagnosis. REP-529 was positive in 97.23%, whereas B1 amplified only 78.80%. After comparing several samples in a Brazilian referral laboratory, this study concluded that REP-529 primer set had better performance than B1 one. These observations were based after using cases with defined clinical diagnosis, ELISA, and conventional PCR. Copyright © 2017 Sociedade Brasileira de Infectologia.

    We determined, in our surrounding environment, the proportion of patients being treated with infliximab who required a therapeutic scheme escalation (an infliximab dose increase surpassing the level of 3 mg/kg every 8 weeks and/or a decrease on the current between infusions' interval). This was a study of the retrospective analysis of data from the 41 rheumatoid arthritis (RA) patients receiving an infliximab therapy at the Albert Einstein Israelita Hospital, from January 2001 up to December 2005. A questionnaire was applied to these patients, assessing their clinical and laboratory data, adverse events, and individual information regarding the infliximab administration. Therapeutic dose information was available in 68% (28/41) of the RA patients, with 46% of these (13/28) receiving a dose increase, and 30% (8/27) experiencing a shortening of the between infusions' interval. The average final infliximab dose (4.21 mg/kg) was significantly greater than their average initial dose (3.29 mg/kg). The average time intervals between the initial and final infusions, though shortened, were not significantly different. A proportion of 73% (30/41) of these patients demonstrated improvement in at least one of the assessed clinical parameters, and 50% of these patients (15/30) experienced a dose increase, while 20% (6/30) experienced shortening of the between treatments' interval. A total of 20% (8/41) of the original patients experienced adverse events. Although infliximab is effective in the control of RA, dose adjustment and/or shortening of the between treatments' interval is frequently required.

    Full Text Available The present work describes a retrospective study of clinical cases of ehrlichiosis in dogs examined from March 1998 to September 2001. From the clinical records with laboratorial confirmation of Ehrlichia canis or E. platys infections, the following parameters were analyzed: demographic aspects (age, race, sex, period of the year and origin, clinical characteristics (body temperature, exposure to ticks and clinical signs, and hematological characteristics (blood cell counts and type of infected cell. A total of 194 clinical records were analyzed, from which 31 animals were infected with E. canis and 21 animals with E. platys. The number of cases of canine ehrlichiosis increased considerably from the year 2000 onwards, and 24.4% of the cases occurred in 13- to 24-month-old animals, in different urban and per-urban regions of the municipality of Belo Horizonte. The most frequent symptoms were fever, anorexia, apathy, abdominal pain, lymphadenopathy and dispnea. Regarding hematological alterations, 70.3% of the animals presented anemia, 50% presented thrombocytopenia and 30% leukopenia, and most E. canis morulae were seen in monocytes. The results point to the importance of canine ehrlichiosis, as 35.9% of the dogs with suspected hemoparasitic diseases were infected with Ehrlichia canis or E. platys.O presente trabalho descreve um estudo retrospectivo da casuística clínica de erliquiose em cães atendidos entre março de 1998 e setembro de 2001.

    Full Text Available Despite the large number of published cases about oral and maxillofacial pediatric lesions, the literature is scarce on epidemiological studies regarding the prevalence of these entities. This study retrieved oral and maxillofacial pediatric lesions from the Center of Diagnosis of Oral Diseases (CDDB at the Dental School of the Federal University of Pelotas (UFPEL, comprising a 20-year period (1983-2002. From the total of 9,465 biopsies received in this period, 625 (6.6% were from children aged 0 to 14 years. Regardless of the histopathological diagnosis, patient data referring to lesion location, sex and age were collected. Diagnoses were grouped in 13 categories. As much as 89% of the cases occurred in patients aged 7 to 14 years (53% in females and 47% in males. Mucocele (17.2% was the most common type of lesion, followed by dentigerous cyst (8.6%. In the category of odontogenic tumors, odontoma was the most frequent lesion (64.2%. Malignant lesions were observed in a small section of the sample (1.2%. Generally, the results of the present study are in line with those reported in the literature concerning the most prevalent lesions in the pediatric population. Most lesions were benign, and malignant lesions were diagnosed in a very small part of the sample.

    Full Text Available INTRODUTION: A major concern with the visceral leishmaniasis (VL is its high lethality rate, even with proper treatment. Low age, prior malnutrition, disease duration prior to diagnosis, severe anemia, fever for more than 60 days, diarrhea and jaundice are known poor prognostic factors. The goals of this study are to describe the clinical and laboratory characteristics of VL among children under 12 years of age and to identify the factors associated with VL poor outcome. METHODS: Two hundred and fifty children under 12 years of age with confirmed VL admitted to Hospital João Paulo II (FHEMIG, Belo Horizonte, Brazil, between January 2001 and December 2005 were evaluated retrospectively. The primary outcome was the poor clinical evolution: sepsis, and/or pneumonia, and/or urinary tract infection, and/or of bleeding (expect epistaxis, and/or severe neutropenia (neutrophil < 500 cells/mm3. Odds ratio (crude and adjusted and its 95% confidence interval for each variable were calculated. Values less than 0.05 were considered significant. RESULTS: Average age was 3.3 years (3.6 months-11.6 years, 71.2% were younger than 5 years and 47.2% lived in Metropolitan Area of Belo Horizonte. The mean fatality rate was 3.6%. Sixty-six (26.4% patients presented poor evolution. After a multivariate analysis, age <18 months, abnormal respiratory physical examination on hospital admission, and platelets <85,000/mm3 remained associated with increased chance of poor evolution. CONCLUSIONS: The results suggest that patients aged between 12 and 18 months, with platelet counts bellow 85,000/mm3, and respiratory abnormalities at admission should be considered potentially severe.

Our fidings indicate that the prevalence of pheochromocytoma was equal in men and women, and most patients (56% were in their second and third decades of life. In 10% of the cases, the disease was bilateral, and in 13% it was outside the adrenal (totally para-aortic. The tumor was more common on the right side (8%, and 3.5% were familial. Almost all cases had a history of hypertension and hypertensive crises. Attack-like episodes of clinical symptoms and signs and hypertension were observed in 98%, headache in 71% and profuse perspiration in 68% of the cases. An abdominal mass was palapated in 13% of the cases, 26% had overt diabetes, 23% had ECG changes. Malignancy was observed in 4%, with metastases to the liver (n=2 lung (n=1 and spine (n=1. In the latter four cases, the metastic lesion was histologically proven to be pheochromocytoma. In three of the 28 female cases, the first hypertensive crisis occurred during pregnancy causing abortion in one case.

    Full Text Available Abstract Background Multidrug-resistant tuberculosis (MDR-TB is a threat for the global TB epidemic control. Despite existing evidence that individualized treatment of MDR-TB is superior to standardized regimens, the latter are recommended in Brazil, mainly because drug-susceptibility tests (DST are often restricted to first-line drugs in public laboratories. We compared treatment outcomes of MDR-TB patients using standardized versus individualized regimens in Brazil, a high TB-burden, low resistance setting. Methods The 2007–2013 cohort of the national electronic database (SITE-TB, which records all special treatments including drug-resistance, was analysed. Patients classified as MDR-TB in SITE-TB were eligible. Treatment outcomes were classified as successful (cure/treatment completed or unsuccessful (failure/relapse/death/loss to follow-up. The odds for successful treatment according to type of regimen were controlled for demographic and clinical variables. Results Out of 4029 registered patients, we included 1972 recorded from 2010 to 2012, who had more complete outcome data. The overall success proportion was 60%. Success was more likely in non-HIV patients, sputum-negative at baseline, with unilateral disease and without prior DR-TB. Adjusted for these variables, those receiving standardized regimens had 2.7-fold odds of success compared to those receiving individualized treatments when failure/relapse were considered, and 1.4-fold odds of success when death was included as an unsuccessful outcome. When loss to follow-up was added, no difference between types of treatment was observed. Patients who used levofloxacin instead of ofloxacin had 1.5-fold odds of success. Conclusion In this large cohort of MDR-TB patients with a low proportion of successful outcomes, standardized regimens had superior efficacy than individualized regimens, when adjusted for relevant variables.

    Patients burned intentionally experience extensive injuries with high rates of morbidity and mortality. Nonetheless, there is no consensus if these patients have worse outcomes than unintentional burns considering injury severity and other preexistent comorbidities. We conducted a ten-year retrospective review on all patients treated at the Burn Unit of Hospital de Pronto Socorro, Porto Alegre, Brazil, between 2003 and 2012. The aim was to compare survival of self-inflicted burns and burns from assaults with unintentional injuries using a Multivariable Cox Regression Analysis. 1734 patients were included in the study, 87.7% non-intentional, 6.6% self-inflicted and 5.8% from aggression. Intentional injuries resulted in more severe injuries and were associated with psychiatric disorders and drug abuse. After controlling for injury severity, previous clinical comorbidities and previous psychiatric disorders, only self-inflicted burns correlated significantly with a higher risk of death (HR=1.59, CI 95% 1.05-2.41, p=0.03). Self-inflicted injuries were independently associated with a higher risk of death. Burns from aggression were not associated with higher mortality in this model. Prevention of these injuries must be priority and treating the main associated factors such as drug abuse and psychiatric disorders may lower its occurrence. Copyright © 2014 Elsevier Ltd and ISBI.

    To examine the use of medication of top-level male players during the 2014 FIFA World Cup Brazil. Retrospective survey. 736 top level players. The teams' physicians disclosed a list of the medications used by each player within 72 h before each match of the 2014 FIFA World Cup Brazil. Average number of medications used per player per match or during the tournament; average number and percentage of players using at least one medication per match or during the tournament. 67.0% of all players took various types of medication during the tournament. The most used medications during the tournament were non-steroidal anti-inflammatory drugs (NSAIDs), by 54.2% of all players, followed by analgaesics (12.6%); β-2 agonists were only used by 0.5%. On average, 0.8 medications per player were used before each match. More players were reported taking medications during the knockout round than during the qualification round (0.36±0.48 vs 0.49±0.50, pFIFA World Cup. Although the intake of NSAIDs per match (0.35±0.46 vs 0.31±0.48, pFIFA World Cup decreased compared to the 2010 FIFA World Cup, the average use was still higher than in the 2006 FIFA World Cup, and the average number of all used medications per player remained the same level as 4 years prior, with all its implications for the player's health. More efforts need to be undertaken worldwide in order to reduce the administration of medications in sports, through continuous education for players, starting from a young age, as well as for doctors and paramedics.

    Full Text Available Leishmaniasis is zoonosis caused by pleomorphic protozoa of the genus Leishmania. The spread of the disease in Brazil lead to this retrospective survey of canine visceral leishmaniasis diagnosed at the Service of Dermatology and Medical Clinics of the Small Animal Hospital-USP. We evaluated the records of 36 dogs naturally infected with Leishmania sp, which diagnosis included disease characterization during anamnesis, physical and dermatologic examination, hematology, biochemistry, imaging, serology (Enzyme-Linked Immunosorbent Assay – ELISA and/or Indirect Fluorescent Reaction – RIFI, skin histopathology and/or agent isolation from aspiration biopsy samples of lymph nodes and/or bone marrow, and immunohistochemistry. All cases were allochtonous without gender predilection; 52.8% were 13 to 48 months old, with greater occurrence in pure breed dogs (66,7%, mostly Poodles and Labradors (20.8% each. Regarding origin: Campinas, Campo Limpo Paulista, Holambra, Ilha Bela, São Roque, Sorocaba, Ubatuba and Uberaba (one case / city.

    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.

    Usage of data from electronic health records (EHRs) in clinical research is increasing, but there is little empirical knowledge of the data needed to support multiple types of research these sources support. This study seeks to characterize the types and patterns of data usage from EHRs for clinical research. We analyzed the data requirements of over 100 retrospective studies by mapping the selection criteria and study variables to data elements of two standard data dictionaries, one from the healthcare domain and the other from the clinical research domain. We also contacted study authors to validate our results. The majority of variables mapped to one or to both of the two dictionaries. Studies used an average of 4.46 (range 1-12) data element types in the selection criteria and 6.44 (range 1-15) in the study variables. The most frequently used items (e.g., procedure, condition, medication) are often available in coded form in EHRs. Study criteria were frequently complex, with 49 of 104 studies involving relationships between data elements and 22 of the studies using aggregate operations for data variables.

    Background Odontogenic tumors (OTs) are considered important among oral lesions because of their clinicopathological heterogeneity, and variable biological behavior. This paper aims to determine the frequency and distribution of OTs, over a period of 10 years, at a public university in Northeastern Brazil and compare this data with previous reports. Material and Methods We reviewed all cases of OTs from oral pathology laboratory of University of Pernambuco (UPE), from 2004 to 2014. Diagnoses were re-evaluated and the tumors were classified according to the latest (2005) World Health Organization Classification of Tumors. In addition, we searched in the English-language literature retrospective studies on OTs that used the same classification. Results Data was obtained allowing the analysis of the tissue hemodynamics. We were able to map the vascularization of the face and it was possible to access three arteries of small diameter (0,60mm angular artery; 0,55mm greater palatine artery; 0,45mm infraorbital artery). Conclusions OTs are uncommon neoplasms with geographic variation. Our clinicopathological features are according to literature. In the present study, KCOT was the most frequent one, showing that the new classification of OTs altered the distribution of these lesions and possibly made KCOT the most common OT observed in diagnostic services worldwide. Key words:Odontogenic tumors, jaw neoplasms, epidemiology, oral pathology. PMID:26827068

    To describe the chromosomal alterations in patients with mental retardation (MR) using G-banding karyotype analysis. A retrospective study of the results G-banding karyotype analysis of 369 patients investigated for MR was performed. Based on the structural rearrangements found, the authors searched all chromosomal regions related with breakpoints, and these were compared with the literature on MR and databases. 338 (91.6%) normal cases, and 31 (8.4%) with some type of chromosomal abnormality were identified. Among the altered cases, 21 patients (67.8%) were identified with structural chromosomal alterations, nine (29%) with numerical alterations, and one (3.2%) with numerical and structural alterations. Structural chromosomal abnormalities were observed more frequently in this study. G-banding karyotyping contributes to the investigation of the causes of MR, showing that this technique can be useful for initial screening of patients. However, higher resolution techniques such as array based comparative genomic hybridization (aCGH) and multiplex ligation-dependent probe amplification (MPLA) can detect submicroscopic alterations commonly associated with MR.

    This is an analysis of 102 cases of SIDS from retrospective studies in the Zilina and Senica districts. The incidence of SIDS in the Zilina district was 2.04/1000 (period 1969-1978) and 1.04/1000 (period 1980-1984). The incidence of SIDS in the Senica district was 0.82/1000 (period 1979-1990). According to preliminary results of the epidemiological study of SIDS in Slovakia (1991) the incidence is only 0.89/1000 which amounts, however, to 23.1% of the post-neonatal mortality. In the investigation nine indicators were evaluated: age at the time of death, morbidity before death, place of death, education of mother, position of infant at time of death, birth weight succession of child in family. The assembled results were compared with data in the literature. Because of similar results it is assumed that the following risk factors participate in the incidence of SIDS: age (2-4 months), time between midnight and 6 a.m., low socio-economic status of family, lower education of mother, incidence of SIDS in the family, short interval between childbirths, prone position during sleep, succession of child in family (third or subsequent), effect of smoking. The investigation did not confirm as risk factors a lower birth weight and inadequate postnatal adaptation. In the conclusions some possible ways of prevention are outlined.

    This study evaluates the clinical features of contact granuloma and compares the results of voice therapy in operated versus unoperated cases. Retrospective review of 123 patients with contact granuloma. Thirty-six patients had undergone one or more surgeries before phoniatric consultation. After their final operation, 33 patients had recurrence. The three patients who were cured by operation were not studied further. The course of disease in the 33 patients with recurrence was compared with that of 87 patients who did not have surgery. The hospital records were reviewed concerning age, sex, symptoms, side of granuloma, and outcome of treatment. The predominant symptoms were vocal fatigue, vocal discomfort, the need for excessive throat clearing, and hoarseness. The recurrence rate after operation was 92%. Twelve months after voice therapy, 35% of the operated group and 51% of the unoperated group were cured. The patients who had surgery had almost twice as many sessions of voice therapy as the unoperated group, and their mean recovery time was 17 months, compared with 8 months for the unoperated group. The recurrence rate after surgery was high. Surgery may prolong the recovery time. Subjective symptoms diminished during voice therapy, but we cannot confirm that it was beneficial for the healing process.

    Full Text Available BACKGROUND Penetrating abdominal injuries forms an important component of surgical emergencies. It remains one of the commonest reasons for preventable deaths in any trauma systems. 1 Abdominal injuries may be parietal or visceral or perforating through and through injury. Unnecessary exploration leads to increased morbidity. The goal in managing penetrating abdominal injuries is to identify and treat all the damages caused by the weapon and to reduce negative laparotomy and avoid missed injuries. MATERIALS AND METHODS A retrospective study that was carried out in 53 patients in Government Kilpauk Medical College and Government Royapettah Hospital from May 2007 to July 2009 on penetrating injuries abdomen. RESULTS Among 53 patients, maximum number of cases were in the age group of 30-40 years. Assault injuries account for 87% of cases of penetrating abdominal injuries. Small bowel was the commonly injured organ in this study. Laparotomy was therapeutic in 94% of the cases (64% of the cases underwent laparotomy. CONCLUSION Careful and serial clinical examination and appropriate diagnostic investigations leads to successful treatment in these patients. Computed tomography is highly sensitive in predicting both peritoneal penetration and intra-abdominal visceral injuries.

From 4,884 cattle specimens, sent by practitioners or which were from necropsies performed at the Diagnostic Laboratory, 231 (4.7% were diagnosed as tick fever. Data from 221 of those outbreaks were analyzed. Ninety one (41.1% outbreaks were caused by Babesia bovis, 11 (4.9% by Babesia bigemina, and 65 (29.41% by Anaplasma marginale. In other 33 (14.93% outbreaks of babesiosis there is no information if the disease was caused by B. bovis or B. bigemina, and 21 (9.5% outbreaks were caused by mixed infection of A. marginale and B. bovis or B. bigemina. Mean morbidity, mortality, and letality rates in 149 outbreaks were 11.17%, 6.81%, and 70.04%, respectively. Most outbreaks occurred during summer (January-March and autumn (April-June, mainly in 1 to 3-year-old cattle. Clinical signs were depression, weakness, fallen ears, fever, and weight loss. Low packed cell volume values were always found. Hemoglobinury was observed in babesiosis. Neurological signs characterized by gait alterations, muscular tremors, aggressiveness and falling down with tonic and clonic convulsions were observed in babesiosis by B. bovis. The main gross lesions were anemia, jaundice, splenomegaly, hepatomegaly, yellow liver and cardiac hemorrhages. Hemoglobinury was observed in babesiosis, and congestion of the cerebral cortex in babesiosis by B. bovis. It is concluded that B. bovis is the main agent causing thick fever in southern Rio Grande do Sul. In that region with a cattle population of 2,630,000 heads the annual losses due to tick fever can be estimated in 6,220 cattle or

    To describe the use of hydrotherapy for pain management in labor. This was a retrospective cohort study. Hospital labor and delivery unit in the Northwestern United States, 2006 through 2013. Women in a nurse-midwifery-managed practice who were eligible to use hydrotherapy during labor. Descriptive statistics were used to report the proportion of participants who initiated and discontinued hydrotherapy and duration of hydrotherapy use. Logistic regression was used to provide adjusted odds ratios for characteristics associated with hydrotherapy use. Of the 327 participants included, 268 (82%) initiated hydrotherapy. Of those, 80 (29.9%) were removed from the water because they met medical exclusion criteria, and 24 (9%) progressed to pharmacologic pain management. The mean duration of tub use was 156.3 minutes (standard deviation = 122.7). Induction of labor was associated with declining the offer of hydrotherapy, and nulliparity was associated with medical removal from hydrotherapy. In a hospital that promoted hydrotherapy for pain management in labor, most women who were eligible initiated hydrotherapy. Hospital staff can estimate demand for hydrotherapy by being aware that hydrotherapy use is associated with nulliparity.

    A retrospective study was carried out on Genitourinary Rhabdomyosarcoma in the Department of Paediatric Surgery of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh during the period January 1990 to December 1999. Total thirteen patients were treated during this period, age ranging from 1 month to 12 years. Eight patients were male and five were female (M: F = 1.6: 1). Diagnosis was made by history, thorough physical examination, digital rectal examination, ultrasonography, intravenous urography, CT scan and biopsy. All the patients were treated with chemoradiation theraphy as a first line of management and surgical excision was done for local residual tumours. Eight children (61.5%) were asymptomatic after completion of chemo-radiation therapy. Three (23.07%) patients discontinued the chemo-radiation schedule. Residual mass was present in one (7.7%) case for which partial cystectomy was done and the patient died in the 5th post operative day. Another patient (7.7%) who had pulmonary metastasis at the time of diagnosis, died during chemo-radiation therapy.

    Full Text Available Purpose: To determine external, middle, and inner ear abnormalities on high-resolution computed tomography (HRCT of temporal bone in patients with microtia and to predict anatomic external and middle ear anomalies as well as the degree of functional hearing impairment based on clinical grades of microtia. Materials and Methods: It was a retrospective study conducted on Indian population. Fifty-two patients with microtia were evaluated for external, middle, and inner ear anomalies on HRCT of temporal bone. Clinical grading of microtia was done based on criteria proposed by Weerda et al. in 37 patients and degree of hearing loss was assessed using pure tone audiometry or brainstem-evoked response in 32 patients. Independent statistical correlations of clinical grades of micotia with both external and middle ear anomalies detected on HRCT and the degree of hearing loss were finally obtained. Results: The external, middle, and inner ear anomalies were present in 93.1%, 74.5%, and 2.7% patients, respectively. Combined cartilaginous and bony external auditory canal atresia (EAC was the most common anatomic abnormality in our group of microtia patients. Hypoplastic mesotympanum represented the commonest middle ear anomaly. The incidence of combined ossicular dysplasia and facial canal anomalies was lower as compared to other population groups; however, we recorded a greater incidence of cholesteatoma. Both these factors can have a substantial impact on outcome of patients planned for surgery. We found no significant association between grades of microtia and external or middle ear anomalies. Similarly, no significant association was found between lower grades of microtia (grade I and II and degree of hearing loss. However, association between grade III microtia and degree of hearing loss was significant. A significant association between congenital cholesteatoma and degree of pneumatization of atretic plate and mastoid process not previously studied

    Full Text Available Few data are available about progressive multifocal leukoencephalopathy (PML in patients with acquired immunodeficiency syndrome (AIDS from Brazil. The objectives of this study were to describe the main features of patients with PML and estimate its frequency among AIDS patients with central nervous system (CNS opportunistic diseases admitted to the Instituto de Infectologia Emílio Ribas, São Paulo, Brazil, from April 2003 to April 2004. A retrospective and descriptive study was performed. Twelve (6% cases of PML were identified among 219 patients with neurological diseases. The median age of patients with PML was 36 years and nine (75% were men. Nine (75% patients were not on antiretroviral therapy at admission. The most common clinical manifestations were: focal weakness (75%, speech disturbances (58%, visual disturbances (42%, cognitive dysfunction (42%, and impaired coordination (42%. The median CD4+ T-cell count was 45 cells/µL. Eight (67% of 12 patients were laboratory-confirmed with PML and four (33% were possible cases. Eleven (92% presented classic PML and only one case had immune reconstitution inflammatory syndrome (IRIS-related PML. In four (33% patients, PML was the first AIDS-defining illness. During hospitalization, three patients (25% died as a result of nosocomial pneumonia and nine (75% were discharged to home. Cases of PML were only exceeded by cases of cerebral toxoplasmosis, cryptococcal meningoencephalitis, and CNS tuberculosis, the three more frequent neurologic opportunistic infections in Brazil. The results of this study suggest that PML is not an uncommon HIV-related neurologic disorder in a referral center in Brazil.Existe informação limitada sobre a presença da leucoencefalopatia multifocal progressiva (LEMP em pacientes com aids no Brasil.

    The purpose of this study was to analyze the prevalence, demographic patterns and management of odontogenic infections in patients undergoing treatment in an outpatient dental emergency service of a university hospital. In a retrospective study of the year 2012, all patients suffering from odontogenic infections were included. Demographic data, diagnosis and the conducted treatment were analyzed. Odontogenic infections were defined as pulpitis, apical and marginal periodontitis, abscesses and pericoronitis. A total of 2,058 out of 4,209 emergency patients suffered from odontogenic infections. The majority (45.0%) had an apical periodontitis, 20.8% abscesses, 17.3% a marginal periodontitis, 16.3% a pulpitis and 5.8% a pericoronitis. Mean age was 37.5 ± 17.0 years standard deviation (SD) (1.2-96.4). Most patients were 20 to 29 years (24.6%), followed by the age group of 30 to 39 year old patients (21.0%). Males were affected more frequently (55.5%) than females (45.5%). Most of the patients (64.5%) of the patients received a dental or surgical treatment. Antibiotics were prescribed in 31.7% of cases. Amoxicillin was the most common prescribed antibiotic (54.5%). Odontogenic infections represent one of the main reasons for consulting the emergency service. Due to the high number of cases and the severe complications, dentists have to be familiar with the surgical management of odontogenic infections as well as the appropriate use of antibiotics. Nearly half of all patients who sought, treatment in the emergency service had an odontogenic infectious disease. This should be considered for the organization and planning of the service.

    Ameloblastoma is benign odontogenic tumor, usually affecting the posterior region of mandible. It is seen in the third to fifth decades of life. Radiographically the lesion is variable in appearance and may be unilocular or multilocular, with well-defined cortical borders in the mandible and ill-defined margins in the maxilla. To analyze cases of ameloblastoma, with emphasis on the radiographic findings. We also review the current literature briefly and discuss the clinical and radiographic findings. The present hospital-based retrospective study was conducted by reviewing the clinical and radiographic records of ameloblastoma cases from 2009 to 2011, available in the archives of the department. The data of a total of 14 patients were analyzed. We observed that the patients affected with ameloblastoma were in the age-group of 19-68 years. The male: female ratio was 1.3:1. The mandible (78.57%) was more commonly affected than the maxilla (14.28%). Six patients (42.86%) had unilateral involvement and eight cases (57.14%) had bilateral involvement. The multilocular and unilocular types of ameloblastoma were noted in 12 (85.72%) and 2 cases (14.28%), respectively. The soap-bubble (50.00%), spider-web (21.43%), and honeycomb (14.28%) appearances were seen in the multilocular variety. Root resorption of variable degree was distinctly observed in 11 cases (78.57%). Radiographs are an important aid for the diagnosis of oral lesions of various types, especially those that involve bone. It is important for the practicing clinicians to know the salient features of ameloblastoma which are peculiar to the local population.

    Full Text Available BACKGROUND Barring malnutrition and infection, cancer is the most common cause of death in children below the age of 14 years of age. Malignancies are coming into greater focus because of the preventive measures being taken for the former. In general, the features of malignancy in children differ greatly from neoplasm in adults. Tissues which are developing and growing are more likely to undergo neoplastic transformation. Hence, high incidence of embryonic cancers in children. Today, the diagnosis of cancer particularly in children is still regarded as in some circles as death sentences for the malignant disease is second only to trauma and infectious diseases as a killer in children above the age of one year. Hence, early diagnosis and confirmation by haematological and histopathological methods are crucial in early diagnosis and treatment. MATERIALS AND METHODS This study was undertaken to evaluate the incidence and morphological features of malignant neoplasm occurring in children. The present study is a retrospective study undertaken in the Department of Pathology, JJM Medical College, Davangere, over a period of three years, i.e., March 1994-February 1997. The material was obtained from paediatric patients aged from 0-14 years admitted to Chigateri General Hospital, Bapuji Child Health Institute attached to JJM Medical College, Davangere, and Hospitals and nursing homes in and around Davangere. RESULTS 1. This study presents an observation on the paediatric malignancies in relation to age, sex and incidence and in the clinical and morphological findings. 2. The malignant tumours in paediatric age group are less common and they form about 10.90% of malignant tumours occurring at all ages. 3. These tumours show a slight male preponderance compared to females in the ratio of 1.2:1. 4. 38.75% of the tumours were encountered in children below the age of 5 years. Most of the tumours (61.25% occurred between 6-14 years indicating a higher

    2002-05-01

    Full Text Available Salmonella Enteritidis (SE emergiu como um grande problema avícola e de saúde pública no Brasil a partir de 1993. Os estudos epidemiológicos, incluindo a fagotipagem e sonda complementar de rRNA, sugerem a entrada de SE no Brasil via importação de material genético avícola contaminado, provavelmente no final da década de 80. As taxas de crescimento da avicultura brasileira na década de 90 criaram condições favoráveis para a manutenção e proliferação da SE nos plantéis avícolas. Além disso, o uso indiscriminado de antibióticos em aves, particularmente as quinolonas, encorajou a manutenção de lotes positivos para SE. As cepas de SE isoladas de aves têm mostrado alta sensibilidade aos antibióticos de uso comum em avicultura, incluindo as quinolonas. Entretanto, o aumento da resistência antimicrobiana e multirresistência tem sido observado em cepas de origem humana. Os últimos levantamentos realizados no ano de 2001 continuam a mostrar que a SE em materiais avícolas é o principal sorovar responsável pelas infecções humanas. Embora as carcaças de frangos apresentem altas taxas de contaminação por SE, são os ovos e seus derivados - principalmente a maionese caseira - os principais responsáveis pelos surtos humanos. O uso de vacinas específicas em poedeiras e reprodutoras tem se mostrado uma ferramenta auxiliar no controle de SE. O procedimento mais indicado para o controle de SE na avicultura está na aquisição e produção de lotes livres do agente. As rações e matérias primas de origem animal parecem não ser tão importantes na perpetuação do problema de SE, porém, os roedores parecem ser reservatórios ambientais importantes de SE em granjas contaminadas.In Brazil, Salmonella enteritidis (SE emerged as a serious problem in poultry and public health as from 1993. Epidemiological studies, including fagotyping and complementary rRNA probe, suggest that SE entered Brazil via the importation of

    To ascertain the frequency of hyponatremic hypertensive syndrome (HHS) in a cohort of children with hypertensive emergency in a tertiary pediatric hospital. A retrospective review was undertaken among children with hypertensive emergency admitted in our tertiary children hospital between June 2014 and December 2015 with an aim to identify any children with HHS. Three children with HHS were identified during this period. The 3 patients with HHS presented with hypertensive emergency. They were initially managed with Labetalol infusion and thereafter switched to oral anti-hypertensives (combination of Nifedipine sustained release, Hydralazine and Beta Blocker). All 3 were diagnosed to have unilateral renal artery stenosis. One child was lost to follow up, whereas the other 2 underwent renal angioplasty which was followed with normalization of blood pressure. Despite activation of renin angiotensin axis secondary to renal artery stenosis, these groups of children have significant hyponatremia. Renal re-vascularisation produces excellent results in most of them.

    Astronaut back pain is frequently reported in the early phase of space flight as they adapt to microgravity. The epidemiology of space adaptation back pain (SABP) has not been well established. This presentation seeks to determine the exact incidence of SABP among astronauts, develop a case definition of SABP, delineate the nature and pattern of SABP, review available treatments and their effectiveness in relieving SABP; and identify any operational impact of SABP. A retrospective review of all available mission medical records of astronauts in the U.S. space program was performed. It was revealed that the incidence of SABP has been determined to be 53% among astronauts in the U.S. space program; most cases of SABP are mild, self-limited, or respond to available treatment; there are no currently accepted preventive measures for SABP; it is difficult to predict who will develop SABP; the precise mechanism and spinal structures responsible for SABP are uncertain; there was no documented evidence of direction operational mission impact related to SABP; and, that there was the potential for mission impact related to uncontrolled pain, sleep disturbance, or the adverse side effects pf anti-inflammatory medications

    Full Text Available Otomycosis is a fungal infection of the external ear canal with only a few studies about its real frequence in Brazil. AIM: to evaluate otomycosis frequence and characteristics in patients with clinical suspicion of external otitis. STUDY DESIGN: Retrospective study with transversal cohort (2000-2006. MATERIALS AND METHODS:103 patients were assigned to mycological diagnosis (direct microscopic examination and culture. RESULTS: Otomycosis was diagnosed in 19.4% of the patients. Patient age varied from 2 to 66 years (an average of 23.5 years of age, and 60% of otomycosis cases were seen in women between 2 to 20 years of age. Chronic otitis, previous antibiotic therapy and the lack of cerumen were predisposing factors; itching, otalgia, otorrhea and hypoacusis were the symptoms reported by the patients. The most frequently isolated species were C. albicans (30%, C. parapsilosis (20%, A. niger (20%, A. flavus (10%, A. fumigatus (5%, C. tropicalis (5%, Trichosporon asahii (5% and Scedosporium apiospermum (5%. CONCLUSIONS: Otomycosis is endemic in João Pessoa-PB. Clinical exam and mycological studies are important for diagnostic purposes because otomycosis symptoms are not specific.Otomicose é uma infecção fúngica do conduto auditivo externo com poucos estudos sobre sua real frequência no Brasil.

    2002-09-01

    This article is the first in a series of international case studies developed by the American Cancer Society to illustrate use of publicly available surveillance data for regional tobacco control. A descriptive analysis of Brazil and Paraguay cigarette production and trade data from official sources. Per capita cigarette consumption for Brazil and its neighbour was calculated from 1970 to 1998 using data on production, imports, and exports from NATIONS, the National Tobacco Information Online System. A 63% decrease was observed in the estimate of per capita consumption of cigarettes in Brazil between 1986 and 1998 (from 1913 cigarettes per person in 1986 to 714 cigarettes per person in 1998) and a 16-fold increase in Paraguay was observed during the same period (from 678 cigarettes per person in 1986 to 10 929 cigarettes per person in 1998). Following Brazil's 1999 passage of a 150% cigarette export tax, cigarette exports fell 89% and Brazil's estimated per capita consumption rose to 1990 levels (based on preliminary data). Per capita consumption in Paraguay also fell to 1990 levels. These trends coincide with local evidence that large volumes of cigarettes manufactured in Brazil for export to Paraguay are smuggled back and consumed as tax-free contraband in Brazil. It is hoped that this case study will draw wider public attention to the problems that smuggling presents for tobacco control, help identify other countries confronting similar issues, and stimulate effective interventions.

    Full Text Available Background: "Mental disorder" is the most common used term in the modern life and the main reason behind this may be the mechanical way of life or stress and strain among youth. Aim: To find the pattern of mental disorders of hospitalized patients in a medical college hospital from 1 st April 2005 to 31 st March 2010. Settings and Design: A retrospective study conducted among the patients admitted with mental disorders in a medical college hospital from 1 st April 2005 to 31 st March 2010. Materials and Methods: Data collected from the registers maintained in the medical records department. Statistical Analysis: Z test is used for the comparison of proportions. Results: A total of 7908 mental disorder cases reported in the medical college hospital, 5564 (70.36% were males and 2344 (29.64% were females. Most cases occurred in the age group of 30-44 years. Mental disorder was more among females than males in 0-29 years and ≥ 60 years, but in 30-59 years males were more. In each year, mental disorders were reported more in males than females. Of the cases, most of them were mood disorders. Mental and behavioral disorders due to psychoactive substance use were more among males but schizophrenia, delusional disorders, mood disorders, stress-related disorders, mental retardation, and so on were more among females. Conclusion: Mood disorder was the most occurred mental disorder and the next leading mental disorder was mental and behavioral disorders due to psychoactive substance use. Counseling can be helpful for preventing most of the mental disorders. Improve the mental health care facilities will be the solution for controlling the mental disorders.

    2012-01-01

    Objective: This article presents the results of a retrospective study of the frequency and classification of odontogenic tumors recorded at four centers of diagnostic pathology in Rio de Janeiro, Brazil. Study Design: All medical records and microscopic slides of odontogenic tumor specimens for the years 1997 to 2007 were retrieved from the files of four services of diagnostic pathology in Rio de Janeiro City. Diagnoses were re-evaluated and the tumors classified according to the latest (2005) World Health Organization Classification of Tumors. Results: A total of 201 odontogenic tumors were found among 15,758 oral biopsies (1.3%). The frequencies of these tumors at the four centers ranged from 0.5% at the National Cancer Institute to 3.3% in a private laboratory. Chi-square analysis revealed statistically significant differences (p<0.05) between the proportions of odontogenic tumors in the studied centers. Of these, 94.5% were benign and 5.5% were malignant. Keratocystic odontogenic tumor (32.3%) was the most frequent lesion, followed by ameloblastoma (29.8%) and odontoma (18.4%). Conclusions: Odontogenic tumors are uncommon in Brazil. Different pathology laboratories reported divergent frequencies of odontogenic tumors, which may reflect institutional specializations and the patient populations served. Key words:Odontogenic tumors, jaw neoplasms, epidemiology, WHO classification. PMID:22143740

  19. URBAN WATERSHED STUDIES IN SOUTHERN BRAZIL

    Directory of Open Access Journals (Sweden)

    Cristiano Poleto

    2007-01-01

    Full Text Available One of the greatest problems observed in Brazilian urban watersheds are concerned to the amount of solid residues, domestic sewerage and sediments that are disposed in the rivers and streams that drain those areas. This project aims to present these problems through a study of case taken in an urban watershed in Porto Alegre city, Southern Brazil. For this study, different procedures were used, such as field surveys, interviews with the inhabitants, satellite images, sediment samples, flow measures and morphology assessment of part of the local fluvial system to check the degree of instability of the channel. In 2005, it was verified that 42.57% of the watershed was impermeable, considering the paved streets, the residential and commercial buildings and stone pavements. As there was no sewer treatment, most of this sewerage was directly disposed into the stream and the TOC has reached 20% (m/m. Moreover, the occupation of riparian areas, a great amount of soil exposed in the watershed, the nonpaved streets and a great volume of solid residues were causing the instability in the channel, silting the stream bed. The metals (Zn, Pb and Cr selected for this study are most frequently found in high concentrations in urban areas. The results suggest the occurrence of a high enrichment of the fluvial sediment by these metals. The concentrations of these elements vary temporally during storms due to the input of impervious area runoff containing high concentration of elements associated to vehicular traffic and other anthropogenic activities. Then, it is possible to conclude that the contamination of the urban watershed is reflected in the results obtained in the fluvial suspended sediments.

    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.

    Minimal Intervention Dentistry (MID) is an effective treatment approach with increasing acceptance among dental professionals. This study aimed to evaluate the MID impact on Dentistry by analyzing procedures performed on patients treated at a Pediatric Dentistry Graduate Program clinic which implemented MID. The number of procedures including sealants, modified atraumatic restorative treatment (mART), resin crowns, direct pulp capping, pulpotomy, pulpectomy, and deciduous/ permanent extractions from 333 pediatric patients treated between the years 2001 to 2003 and 2008 to 2010 in Distrito Federal, Brazil were analyzed. Statistical analysis involved chi-square and G Williams tests. 783 procedures were analyzed and demonstrated that there was a significant reduction of sealant placement in the last triennium when compared to the first one (ppulpectomy (p=0.0002). Based on the results, MID represented a positive impact on the intervention on caries lesions in patients, mainly reflected by the significant reduction in the number of direct pulp capping, pulpotomy and pulpectomy.

    Full Text Available Background. Autoimmune process and immunosuppressive therapy of pemphigus vulgaris would predispose the patients to infections. Aim. We aimed to study the prevalence of infection and pathogenic agents in pemphigus vulgaris patients admitted to dermatology service. Material and methods. This retrospective study was conducted on 155 pemphigus vulgaris patients (68 males, 87 females admitted to dermatology service between 2009 and 2011. In this study, the diagnosis of pemphigus vulgaris was confirmed by light microscopic and direct immunofluorescence findings. Data were collected through a questionnaire. Results. Of 155 pemphigus vulgaris patients, 33 had infection at admission and 9 acquired nosocomial infection. In addition, 37 cases of oral candidiasis and 15 cases of localized herpes simplex were recorded. Totally, 94 cases of infection were recorded. The occurrence of infection was significantly related to the severity of disease, number of hospital admissions, and presence of diabetes mellitus. The most common pathogenic germs isolated from cultures were Staphylococcus aureus and Escherichia coli. Conclusion. Severity of pemphigus vulgaris and diabetes were directly related with tendency to infections. Staphylococcus aureus and Escherichia coli were the most common pathogenic agents. Due to limitations of retrospective study, a prospective study is recommended.

    A recently published retrospective chart review of aerodynamic profiles of women with primary muscle tension dysphonia by Gillespie et al (2013) identified various relationships between mean airflow rate (MFR) and estimated subglottal pressure (est-Psub). The current retrospective study expanded the diagnostic categories to include all voice disorders referred for voice therapy. Three research questions were proposed: (1) Are there differences in the MFR and the est-Psub compared with the normal control group? (2) Within the disordered population, are there different variations in the pairing of MFR and est-Psub? (3) If these variations exist, are they diagnosis specific? A retrospective chart review of patients seen for acoustic and aerodynamic voice assessment at the Emory Voice Center between January 1, 2013 and December 31, 2014, were examined for aerodynamic measures of est-Psub and MFR; of these, 192 met the inclusion criteria. Simple t test, two-step cluster analysis, and analysis of variance, as well as Tukey multiple comparisons, were performed using R and SPSS. Mean est-Psub was significantly greater in the group with voice disorder than in the control group (P value < 0.001). However, no statistical significance was found when comparing the MFR with the control group (P value <0.59). Nine possible pairings of MFR and est-Psub were found. Sufficient evidence was not found to detect significant differences in these pairings across diagnostic groups. With regard to the rate and interrelationships of MFR and est-Psub, the findings of this study are similar to those of Gillespie et al, that is, MFR and est-Psub are not determinate of diagnosis.

    Full Text Available OBJECTIVES: To assess epidemiologic characteristics of penile cancer in Brazil. MATERIALS AND METHODS: From May 2006 to June 2007, a questionnaire was distributed to all Brazilian urologists. Their patients' clinical and epidemiological data was analyzed (age, race, place of residence, history of sexually transmitted diseases, tobacco smoking, performance of circumcision, type of hospital service, as well as the time between the appearance of the symptoms and the diagnosis, the pathological characteristics of the tumor (histological type, degree, localization and size of lesion, stage of disease, the type of treatment performed and the present state of the patient. RESULTS: 283 new cases of penile cancer in Brazil were recorded. The majority of these cases occurred in the north and northeast (53.02% and southeast (45.54% regions. The majority of patients (224, or 78.96% were more than 46 years of age while only 21 patients (7.41% were less than 35 years of age. Of the 283 patients presenting penile cancer, 171 (60.42% had phimosis with the consequent impossibility to expose the glans. A prior medical history positive for HPV infection was reported in 18 of the 283 cases (6.36%. In 101 patients (35.68% tobacco smoking was reported. The vast majority of the cases (n = 207; 73.14% presented with tumors localized in the glans and prepuce. In 48 cases (16.96% the tumor affected the glans, the prepuce and the corpus penis; in 28 cases (9.89% the tumor affected the entire penis. The majority of the patients (n = 123; 75.26% presented with T1 or T2; only 9 patients (3.18% presented with T4 disease. CONCLUSION: Penile cancer is a very frequent pathology in Brazil, predominantly affecting low income, white, uncircumcised patients, living in the north and northeast regions of the country.

    In view of the growing number of examinations proposed and employed for the diagnosis of diseases of the thyroid, a retrospective evaluation was made of their validity in a series of 2500 patients (1500 operated). Attention was paid to scintiscanning, oncotropic indicators, echography, needle biopsy, thyrolymphography and thyroid hormones as aids to determining the nature of thyroid lesions and the planning of their treatment. Scintiscanning and needle biopsy proved of primary importance in determination of the nature of a lesion. Echography supplied additional, though not necessarily indispensable information. Oncotropic indicators and thyrolymphography do not appear to be useful. They do not provide data enabling a diagnostic problem to be solved, but can only help to increase any doubts that may exist. Determination of thyroid hormones is clearly indicated when planning the management of hot lesions (single, multiple or disseminated nodes), in cold lesions where thyroiditis is suspected, and in all cases where the clinical evidence suggests hypothyroidism. In euthyroid subjects requiring surgery with no objective signs of hypofunction, preoperative determinations appear to be unnecessary, where as post-operative values are of assistance in assessing the functional efficiency of the residual thyroid tissue. The conclusion to be drawn, therefore, is that diagnostic examinations should be employed in a more selective and discriminating manner.

    To investigate the risk factors for developing GDM among Taiwanese pregnant women. A retrospective cohort and case-control study. At a medical centre in Southern Taiwan. The hospitalised pregnant women who were diagnosed with either GDM or normal glucose tolerance (NGT) between 1997 and 2011. The glucose tolerance test results were interpreted according to criteria established by the National Diabetes Data Group for GDM. Participants were divided into either a GDM group (case group) or a normal glucose tolerance (NGT) group (control group) in order to determine the risk factors for GDM. With a retrospective chart review, data regarding demographics, a family history of diabetes, history of gestation, and physiological index for pre- and postpregnancy periods were collected. χ(2) tests and independent t tests were used to examine the correlations between demographic characteristics and GDM. Stepwise multivariate logistic regression was used to determine the factors associated with GDM. The results of the comparison between the GDM group (n=106) and the NGT group (n=406) showed that the risk factors for GDM were maternal age, education, a family history of diabetes, and prepregnancy body mass index (BMI). Older age, lower levels of education, a family history of diabetes, and higher prepregnancy BMI were significant risk factors for GDM. In addition to performing risk factor assessment, health care providers should proactively promote the importance of GDM screening to pregnant women at their first antenatal visit.

    Purpose: During the first part of the 20th century, {sup 226}Ra was the most used radionuclide for brachytherapy. Retrospective accurate dosimetry, coupled with patient follow up, is important for advancing knowledge on long-term radiation effects. The purpose of this work was to dosimetrically characterize two {sup 226}Ra sources, commonly used in Sweden during the first half of the 20th century, for retrospective dose–effect studies. Methods: An 8 mg {sup 226}Ra tube and a 10 mg {sup 226}Ra needle, used at Radiumhemmet (Karolinska University Hospital, Stockholm, Sweden), from 1925 to the 1960s, were modeled in two independent Monte Carlo (MC) radiation transport codes: GEANT4 and MCNP5. Absorbed dose and collision kerma around the two sources were obtained, from which the TG-43 parameters were derived for the secular equilibrium state. Furthermore, results from this dosimetric formalism were compared with results from a MC simulation with a superficial mould constituted by five needles inside a glass casing, placed over a water phantom, trying to mimic a typical clinical setup. Calculated absorbed doses using the TG-43 formalism were also compared with previously reported measurements and calculations based on the Sievert integral. Finally, the dose rate at large distances from a {sup 226}Ra point-like-source placed in the center of 1 m radius water sphere was calculated with GEANT4. Results: TG-43 parameters [including g{sub L}(r), F(r, θ), Λ, and s{sub K}] have been uploaded in spreadsheets as additional material, and the fitting parameters of a mathematical curve that provides the dose rate between 10 and 60 cm from the source have been provided. Results from TG-43 formalism are consistent within the treatment volume with those of a MC simulation of a typical clinical scenario. Comparisons with reported measurements made with thermoluminescent dosimeters show differences up to 13% along the transverse axis of the radium needle. It has been estimated that

    The diagnosis of pediatric tuberculosis (TB) presents many challenges, and is further complicated in HIV-infected patients. While many diagnostic systems have been proposed, there is no pediatric TB diagnosis gold standard. The outcomes of four TB diagnostic systems in HIV-infected children were compared in this study. A retrospective cohort study was conducted at a TB/HIV reference hospital in Rio de Janeiro. HIV-infected pediatric patients evaluated for TB from 1998 to 2010 were reassessed using four diagnostic systems: Kenneth Jones, 1969; Tidjani, 1986; Ben Marais, 2006; Brazilian Ministry of Health, 2010. Results were compared to standardized diagnoses made by an expert panel of physicians. Of the 121 patients in the study cohort, the expert panel diagnosed 64 as TB and 57 as not TB cases. The Tidjani system showed the highest diagnostic accuracy, with and without the inclusion of microbiological data. The Tidjani and Kenneth Jones systems produced fewer false-positives, and the Ben Marais and Ministry of Health fewer false-negatives. Across systems, there was little agreement between TB diagnoses. In HIV-infected pediatric patients, the Ben Marais and Ministry of Health systems are useful for TB diagnostic screening, whereas the Tidjani and Kenneth Jones systems are best used in a reference center setting.

    Full Text Available The purpose of this stud y was to determine i f women who undergo hormone replacement therapy postmenopausally, will demonstrate less osteoporosis than women who do not undergo H R T. The osteoporosis subjects were 195 women who volunteered to participate in an NIHsponsored double-blind clinical trial entitled Safely and Efficacy of Fluoride Therapy in Osteoporosis. A convenience sample of 78 controls was obtained by inviting women seeking regular medical attention to join an epidemiological investigation of osteoporosis. The data were analyzed using Chisquare and Student’s t-ratio. The study concludes that future retrospective and prospective analyses appreciate the com plexity of the problem in terms of individual risk for osteoporosis.

    To identify the frequency and causes of uveitis leading to visual impairment in patients referred to the Low Vision Service - Department of Ophthalmology - UNIFESP, over a twenty years period. In a retrospective study, medical records of 5,461 patients were reviewed. Data from the first clinical evaluation at the Low Vision Service were collected, patient's age, gender and cause of visual impairment were analyzed. Patients with uveitis had their chart reviewed for anatomical classification and clinical diagnosis. The mean age of the patients referred to the Low Vision Service was 42.86 years and the mean age of patients with uveitis diagnosis was 25.51 years. Retinal disorders were the most common cause of visual impairment (N=2,835 patients; 51.9%) followed by uveitis (862 patients, 15.7%). Uveitis was posterior in 792 patients (91.9% of uveitis) and toxoplasmosis was the most common diagnosis (765 patients, 88.7%). In our study, uveitis represents the second cause of visual impairment in patients referred for visual rehabilitation and toxoplasmic retinochoroiditis was the most common clinical diagnosis. It affects a young working age population with a relevant social and economic impact, but the early diagnosis and treatment can improve the quality of life of these patients.

    The aim of this retrospective study was to perform an epidemiological analysis of all odontogenic tumors treated in the University Hospitals "Ospedali Riuniti" in Ancona and "Policlinico" in Bari, from 1990 to 2015. A retrospective survey of 277 patients treated for odontogenic tumors from 1990 to 2015 was performed. Data were retrieved from the archives of the above quoted Sections of Pathology. The lesions were classified according to 2005 WHO histological classification, and the following variables were analyzed: age, sex, histopathological diagnosis, site distribution, tumor size, and relapses. Peripheral odontogenic tumors were analyzed considering these lesions separately from their central counterparts. In a total of 344 surgical specimens, there were 277 primary tumors and 67 recurrences. As regards primary lesions, there were 185 odontogenic keratocysts (keratocystic odontogenic tumors) (66.8%), 49 ameloblastomas (17.7%), and 40 other benign odontogenic tumors (14.4%). As to malignant tumors, only 3 ameloblastic carcinomas were found (1.1%). The mean age was 46.7 years, with a M:F ratio of 1.8:1. The mandible was the most common site of localization, with 211 cases (76.2%). Also, 21 cases of peripheral odontogenic tumors were found, ameloblastomas being the most common (8 cases, 38.1%). There is a wide variety of cysts, some of which are subject to variations according to sex, localization, and age. Odontogenic tumors are rare neoplasms and appear to show variations according to sex, localization, and age, and may be useful to the clinicians who need to make clinical judgments before biopsy about the most probable diagnosis.

    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

    Ameloblastoma is the most common epithelial odontogenic tumor. It may show locally invasive behavior resulting in recurrence and malignancy. Therefore, appropriate diagnosis of this tumor is necessary. The aim of this study was to evaluate clinicopathological characteristics of ameloblastomas in an Iranian population. We present a 40-year retrospective study of patients diagnosed from 1971 to 2010 in the Department of Oral and Maxillofacial Pathology, Faculty of Dentistry, Mashhad, Iran. Information gathered from patient records included age, gender, tumor location and histologic type. The frequency of odontogenic tumors among all lesions was 2.08% and ameloblastoma with 88 samples demonstrated the greatest prevalence (41.5%). Regarding gender, 60% of samples occurred in males. The mean age of studied patients was 33.02± 15.74 years with a peak of occurrence in the third decade of life. The most frequent location of tumor was the mandibles (93.2%). Eighty five (96.6%) tumors were recorded as benign and 3 (3.4%) as malignant. Of benign tumors, 62 (72.9%), 20 (23.5%) and 3 (3.6%) cases were of conventional, unicyctic and peripheral types, respectively. In contrast to most previous studies, the most common histologic subtype in the present study was plexiform. Knowledge of the incidence of ameloblastoma and its clinicopathologic features including most common location, gender and age distribution in different ethnogeographic backgrounds is necessary for accurate diagnosis and proper treatment.

    The rate of caries progression in primary teeth has rarely been studied, with most studies on early childhood caries reporting the percentage of lesions that remain at a certain stage of disease over a period of time. The aim of the present study was to examine the prevalence and behavior of proximal and occlusal carious lesions in primary teeth among children from low socio-economic status. This retrospective study was based on bite-wing radiographs of 95 children aged 5-12 taken at 6-12 months intervals, with a follow-up period of at least three years. One hundred thirty-five teeth and 141 tooth surfaces were examined. The degree of proximal surfaces and occlusal caries advancement was scored and statistical analyses (Mann-Whitney, Kruskal-Wallis and Kaplan-Meier analysis) were performed to evaluate caries progression rate. The results revealed that approximately 0.8 years were required for a carious lesion to progress from the outer enamel to the dentino-enamel junction, and an additional 1.4 years for it to reach the inner part of the dentin. The caries progression rate found in the present study is more rapid than previously found and affects more the lower socio economic population.

    Full Text Available CONTEXT AND OBJECTIVE: Chordoma is a rare tumor with a high risk of locoregional recurrences. The aim of this study was analyze the long-term results from treating this pathological condition.DESIGN AND SETTING: Cohort study in a single hospital in São Paulo, Brazil.METHODS: This was a retrospective cohort study on 42 patients with chordoma who were treated at Hospital A. C. Camargo between 1980 and 2006. The hospital records were reviewed and a descriptive analysis was performed on the clinical-pathological variables. Survival curves were estimated using the Kaplan-Meier method and these were compared using the log-rank test.RESULTS: Nineteen patients were men and 23 were women. Twenty-five tumors (59.5% were located in the sacrum, eleven (26.2% in the skull base and six (14.3% in the mobile spine. Surgery was performed on 28 patients (66.7%. The resection was considered to have negative margins in 14 cases and positive margins in 14 cases. The five-year overall survival (OS was 45.4%. For surgical patients, the five-year OS was 64.3% (82.2% for negative margins and 51.9% for positive margins. In the inoperable group, OS was 37.7% at 24 months and 0% at five years.CONCLUSION: Complete resection is related to local control and definitively has a positive impact on long-term survival.

    Although the diagnosis of multiple sclerosis (MS) in the paediatric population remains challenging, paediatric-onset MS is increasingly recognized worldwide. We report on the clinical and biochemical features of a Belgian multicentre cohort of paediatric MS patients in a national retrospective descriptive study. Twenty one paediatric MS patients from four Belgian University Hospitals were included. In nine patients, onset of MS was before the age of ten years which makes the study cohort of special interest. We report a higher incidence of acute disseminated encephalomyelitis (ADEM)-like first MS attacks and an overall higher proportion of polysymptomatic episodes than in adult and most paediatric cohorts reported in the literature. The clinical presentation in our cohort was rather severe with high median EDSS-score during the first clinical manifestation and barely more than half of our study patients showing full recovery after their first clinical manifestation. Also, a significant proportion of children in our cohort has severe disease progression despite disease modifying therapy and 9.5% of patients showed transition to secondary progressive multiple sclerosis during adolescence. An early and correct diagnosis of paediatric MS is essential to start early adequate treatment. As illustrated by our study cohort, current treatment options in childhood are unsatisfactory.

    The aim of this study is to review the current management and outcomes of fetal bradycardia in 9 Spanish centers. Retrospective multicenter study: analysis of all fetuses with bradycardia diagnosed between January 2008 and September 2010. Underlying mechanisms of fetal bradyarrhythmias were studied with echocardiography. A total of 37 cases were registered: 3 sinus bradycardia, 15 blocked atrial bigeminy, and 19 high grade atrioventricular blocks. Sinus bradycardia: 3 cases (100%) were associated with serious diseases. Blocked atrial bigeminy had an excellent outcome, except for one case with post-natal tachyarrhythmia. Of the atrioventricular blocks, 16% were related to congenital heart defects with isomerism, 63% related to the presence of maternal SSA/Ro antibodies, and 21% had unclear etiology. Overall mortality was 20% (37%, if terminations of pregnancy are taken into account). Risk factors for mortality were congenital heart disease, hydrops and/or ventricular dysfunction. Management strategies differed among centers. Steroids were administrated in 73% of immune-mediated atrioventricular blocks, including the only immune-mediated IInd grade block. More than half (58%) of atrioventricular blocks had a pacemaker implanted in a follow-up of 18 months. Sustained fetal bradycardia requires a comprehensive study in all cases, including those with sinus bradycardia. Blocked atrial bigeminy has a good prognosis, but tachyarrhythmias may develop. Heart block has significant mortality and morbidity rates, and its management is still highly controversial. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana.

    Full Text Available Background. No consensus between guidelines exists regarding neuroimaging in first-episode psychosis. The purpose of this study is to assess anomalies found in structural neuroimaging exams (brain computed tomography (CT and magnetic resonance imaging (MRI in the initial medical work-up of patients presenting first-episode psychosis. Methods. The study subjects were 32 patients aged 18–48 years (mean age: 29.6 years, consecutively admitted with first-episode psychosis diagnosis. Socio-demographic and clinical data and neuroimaging exams (CT and MRI were retrospectively studied. Diagnostic assessments were made using the Operational Criteria Checklist +. Neuroimaging images (CT and MRI and respective reports were analysed by an experienced consultant psychiatrist. Results. None of the patients had abnormalities in neuroimaging exams responsible for psychotic symptoms. Thirty-seven percent of patients had incidental brain findings not causally related to the psychosis (brain atrophy, arachnoid cyst, asymmetric lateral ventricles, dilated lateral ventricles, plagiocephaly and falx cerebri calcification. No further medical referral was needed for any of these patients. No significant differences regarding gender, age, diagnosis, duration of untreated psychosis, in-stay and cannabis use were found between patients who had neuroimaging abnormalities versus those without. Discussion. This study suggests that structural neuroimaging exams reveal scarce abnormalities in young patients with first-episode psychosis. Structural neuroimaging is especially useful in first-episode psychosis patients with neurological symptoms, atypical clinical picture and old age.

    Adipocytic tumors are the most common soft tissue mesenchymal tumors. Their occurrence in salivary glands is rare. We studied the epidemiology, the diagnostic and the therapeutic features of the salivary adipocytic tumors followed in our department. A retrospective study was conducted in our department between January 1997 and December 2011. Nine cases of adipocytic tumors of the salivary glands were found. Data were collected from medical records and processed by Excel. Mean age was 44 with a clear predominance of males (sex ratio: 3.5). In 8 cases the tumors were benign (7 lipomas and 1 lipofibroma). The only malignant tumor was a metastatic myxoid liposarcoma. Parotid was the main location (8 cases/9). Ultrasonography and MRI were prescribed. The treatment was tumor and parotid gland removal with conservation of the facial nerve excepted in the malignant case. One transient facial palsy, two earlobe dysesthesia and one retromandibular depression were observed. No recurrence was noted. Our study confirmed the epidemiological profile of these adipocytic salivary gland tumors, which are rarely observed, but mainly in the parotid gland. They are often benign and lipoma is the main histological type. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Objectives The objective of the study was to evaluate whether oral cobalamin supplementation can restore normocobal-aminaemia in cats with hypocobalaminaemia and clinical signs of gastrointestinal disease. Methods This was a retrospective study based on a computerised database search for client-owned cats treated at Evidensia Specialist Animal Hospital, Helsingborg, Sweden, during the period December 2013 to August 2016. Inclusion criteria were cats with clinical signs of chronic enteropathy, an initial serum cobalamin concentration ⩽250 pmol/l (reference interval 214-738 pmol/l) and oral treatment with cobalamin tablets. Results Twenty-five cats met the inclusion criteria. The cats were treated with 0.25 mg cyanocobalamin tablets once daily. Serum cobalamin concentration was rechecked 27-94 days after continuous oral cobalamin supplementation. All cats had serum cobalamin concentrations above the reference interval after oral cobalamin supplementation. Median (range) serum cobalamin concentration was 128 pmol/l (111-250 pmol/l) prior to treatment and 2701 pmol/l (738-16,359 pmol/l) after supplementation. This difference was statistically significant ( P cats with hypocobalaminaemia. Thus, oral cobalamin supplementation is a promising alternative to parenteral administration. Prospective comparative studies in cats being treated with parenteral vs oral cobalamin supplementation in a larger number of patients are warranted before oral supplementation can be recommended for routine use.

    Full Text Available Introduction: bite affects about 2 million people every year, with more than 100000 mortalities annually. A person bitten by a snake represents a variety of symptoms. Snake bite might be asymptomatic or with mild local symptoms or even could lead to tissue damage and rapid death. This study aimed to investigate characteristics of snake bite in Northwest Iran. Methods: In this retrospective study, medical records of all patients with final diagnosis of snake bite who were admitted to Sina Clinical-Educational Center, the referral center for envenomation in Northwest Iran were investigated from 2002 to 2012. Demographic information and laboratory findings were collected using a checklist. Results: During a 10 year period, 160 individuals with snake bite were admitted, of which 128 (77.6% were male. With regard to occupation, farmers accounted for the largest portion (n = 57, 34.6%. The most prevalent sites bitten by snakes were right hand (25.5% and left leg (24.8%. Fifty-seven patients (34.5% had leukocytosis and four (2.4% had coagulopathy. Pain and swelling were two main complaints, with vomiting, dizziness, and tingling in extremities coming afterwards. Conclusion: Because snake bite is one of the most important emergencies presenting to emergency department and Iran’s geographic status bears wide spectrum of poisonous snakes, this study was performed to further explore the clinical and epidemiologic details of snake bite.

    PurposeThis study is the first to present the outcomes of the Straub Aspirex device for the salvage of occluded renal dialysis access fistulae.Materials and MethodsThis is a retrospective study, using data from the Renal Unit and Radiology Department database. It included all the patients between 2010 and 2014 who underwent percutaneous mechanical thrombectomy (PMT) treated by JD. Aspirex is an over-the-wire, 6–10 French catheter within which is a rapidly rotating helix which draws thrombus into a window near the tip which it then macerates and removes. Access survival was assessed using the Kaplan–Meier method, and multi-variant analysis was performed using the Cox proportional hazards model. Significance was considered if p < 0.05.ResultsA total of 27 procedures were performed for 19 patients. 13 had autologous arterio-venous fistulae, and 14 had synthetic (PTFE) arterio-venous grafts. 15 were males, 4 females. 100 % of the patients successfully had a channel of thrombus removed. This resulted in an 81.5 % initial clinical success, with primary patency rates of 53.6, 44.3 and 33 % by days 30, 90 and 480, respectively, without significant difference of any analysed covariates. No major complication (pulmonary embolus, paradoxical cerebral infarction, limb ischaemia or significant haemorrhage) occurred.ConclusionAspirex has rates of patency and complication similar to other PMT devices. No covariant studied affected outcome.

    OBJECTIVE: The purpose of this study was to examine the relationship among methadone maintenance treatment, perinatal outcomes, and neonatal abstinence syndrome. STUDY DESIGN: This was a retrospective cohort study of 61,030 singleton births at a large maternity hospital from 2000-2007. RESULTS: There were 618 (1%) women on methadone at delivery. Methadone-exposed women were more likely to be younger, to book late for antenatal care, and to be smokers. Methadone exposure was associated with an increased risk of very preterm birth <32 weeks of gestation (adjusted odds ratio [aOR], 2.47; 95% confidence interval [CI], 1.40-4.34), being small for gestational age <10th percentile (aOR, 3.27; 95% CI, 2.49-4.28), admission to the neonatal unit (aOR, 9.14; 95% CI, 7.21-11.57), and diagnosis of a major congenital anomaly (aOR, 1.94; 95% CI, 1.10-3.43). There was a dose-response relationship between methadone and neonatal abstinence syndrome. CONCLUSION: Methadone exposure is associated with an increased risk of adverse perinatal outcomes, even when known adverse sociodemographic factors have been accounted for. Methadone dose at delivery is 1 of the determinants of neonatal abstinence syndrome.

    Poor social interactions have been recognized as a symptom since the beginnings of psychiatry. As far as socially withdrawn youth (SWY) are concerned, studies were mostly conducted on patients seeking care. Our psychiatric outreach team called Psymobile was able to reach SWY patients who were not seeking mental health care. To identify the clinical and socio-demographic characteristics of SWY patients referred to our Psymobile unit. We carried out a retrospective study on the records of patients aged 18-34 years, who were referred to Psymobile for 'withdrawal', between April 2012 and December 2015. In total, 66 patients were included in the study. SWY are predominantly male (80%) from large families or single-parent ones. About 42% had no prior contact with a mental health professional before being referred to Psymobile. The mean duration of withdrawal is 29 months. In all, 42% of SWY use cannabis and 73% present disorders of the sleep-wake schedule. About 71% maintain relations with their families and 73% go out occasionally. They are mostly diagnosed with schizophrenia (37%) or mood disorders (23%). Over one-third of Psymobile patients aged 18-34 years were referred on grounds of social withdrawal. Our data may illustrate more accurately the situation of youth social withdrawal amid the general population than data from help-seeking patients or online questionnaires.

    To examine the relationship between potential drug interactions and hospital readmissions. Retrospective study with 1,487 adult patients (> 18 years old) admitted to a general hospital in the city of Vitória da Conquista, Northeastern Brazil, from January to December 2007. Data were collected from Hospital Admission Authorization (AIH) forms in the Brazilian National Health System Hospital Database (SIH/SUS). Probabilistic linkage was used to combine multiple AIH forms from the same admission into a single record and to identify readmissions. Information on prescriptions was manually added to the SIH/SUS records. Logistic regression was used to quantitatively assess the impact of drug interactions on hospital readmissions. Cox regression was performed to test the impact of this variable on time to first readmission. A total of 99 readmissions (7% of all patients) were identified. Potential drug interactions were found in 35% of all prescriptions evaluated. Patients with potential drug interactions in a prior admission were more likely to be readmitted. The adjusted odds ratio indicated a 2.4-fold increase in odds of being readmitted; and the adjusted hazard ratio showed that this risk was increased by 79% in patients with potential drug interactions (p < 0.01). The study results suggest an association between prior drug interactions and increased risk of readmission. Health professionals should be aware of potential hazard of certain drug combinations and closely monitor high-risk patients such as elderly patients and those with renal impairment.

    The association of preoperative pain and indirect pulp treatment in permanent teeth is still unknown. This study aimed to evaluate the influence of preoperative pain in the success rate of indirect pulp capping. The sample of this retrospective study was constituted for 133 teeth treated in a Private clinic in Joinvile, Brazil, by one experienced dentist between 2007 and 2012. Data related to clinical and demographic variables that could influence in the success rate of indirect pulp capping were also collected, such patient age and sex, type of teeth and arch. Chi‑square test was used to evaluate the association between preoperative pain with postoperative one and success of the treatment. Logistic regression was performed to identify significant clinical and demographical factors associated with the success of the indirect pulp capping. The overall success rate was 100% in the absence of preoperative pain. However, when the preoperative pain was present, the failure rate was 18.3%. Statistical analysis showed significant association between preoperative pain and postoperative one and failure rate of the indirect pulp capping. The other independent variables were not associated with the success rate of the treatment. The presence of preoperative pain is associated with the decrease of the success rate of indirect pulp capping.

    Full Text Available To report the echocardiographic evaluation of 103 infants with presumed congenital Zika syndrome.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.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.

    Full Text Available The purpose of this retrospective study was to analyze the cases of traumatic dental injuries involving root fracture and/or periodontal ligament injury (except avulsion treated at the Discipline of Integrated Clinic, School of Dentistry of Araçatuba, São Paulo State University (UNESP, Brazil, from January 1992 to December 2002. Clinical and radiographic records from 161 patients with 287 traumatized teeth that had sustained root fracture and/or injuries to the periodontal ligament were examined. The results of this survey revealed that subluxation (25.09% was the most common type of periodontal ligament injury, followed by extrusive luxation (19.86%. There was a predominance of young male patients and most of them did not present systemic alterations. Among the etiologic factors, the most frequent causes were falls and bicycle accidents. Injuries on extraoral soft tissues were mostly laceration and abrasion, while gingival and lip mucosa lacerations prevailed on intraoral soft tissues injuries. Radiographically, the most common finding was an increase of the periodontal ligament space. The most commonly performed treatment was root canal therapy. Within the limits of this study, it can be concluded that traumatic dental injuries occur more frequently in young male individuals, due to falls and bicycle accidents. Subluxation was the most common type of periodontal ligament injury. Root canal therapy was the type of treatment most commonly planned and performed.

    Testicular torsion is a medical emergency that usually requires surgical exploration. However, testicular malignancy has been anecdotally reported with the association of torsion in surgical specimens, and the published data remain scant on the association of torsion with testicular tumors. By retrospective medical record review, we identified 32 patients who had been diagnosed with testicular torsion, 20 of whom had undergone orchiectomy. Of these 20 patients, 2 were diagnosed with a malignancy. Our study, the largest case series to date, has shown an association between testicular torsion and testicular cancer of 6.4%. Testicular torsion is a medical emergency that usually requires surgical exploration. However, testicular malignancy has been anecdotally reported in association with torsion in surgical specimens. However, the published data remain scant on the association between torsion and the presence of testicular tumors. The present retrospective study explored the association between torsion and testicular cancer in patients with testicular torsion undergoing orchiectomy during scrotal exploration. A medical record review was performed of patients who had had a diagnosis of testicular torsion from January 2003 to February 2015. The clinicopathologic characteristics of the patients were recorded. A total of 32 patients were identified. Their mean age was 21.1 years (range, 7-39 years). All the patients had unilateral testicular torsion, which affected the left side in 17 and the right side in 15. Manual detorsion was successful in 6 patients, and 26 patients underwent emergency surgery with testicular detorsion (6 fixation surgery and 20 orchiectomy). The type of incision was scrotal in 6, inguinal in 10, and unspecified in 4. Pathologic examination of the orchiectomy specimens showed malignancy in 2 cases (seminoma and malign mixed germ cell tumor). To the best of our knowledge, the present single-center case series is the largest case series to date of

    Retrospective study analyzing clinical characteristics and treatment of children affected by Leber-Coats' disease. Children with Leber-Coats' disease seen in Edouard-Herriot Hospital, Lyon, between January 2004 and September 2013 were included. The following clinical characteristics were reported: sex, age at diagnosis, presenting symptom, Shields' stage, treatment used, and visual outcomes. Ten children were included in our study. Mean age at diagnosis was 5.5 years. The disease was unilateral in 9/10 cases. The presenting symptom was loss of vision in 7/10 cases, strabismus in 3/10 cases, and microphthalmos in 1 case. The diagnosis was made fortuitously during a follow-up of familial congenital cataract in 2 patients. No cases of leukocoria were seen. Shields' stages were distributed as follows: stage 1, 2A and 2B: 1 case each, stage 3A1: 7 cases, stage>3A1: no cases. Laser photocoagulation was used up to stage 2B, combined with cryotherapy in stage 3A. Stage 1 and 2A were associated with relatively good final visual acuity. Significant macular lipid exudate (stage>2A) was associated with a worse prognosis. These epidemiological data help us to better characterize these patients' prognosis. Early diagnosis seems to improve visual outcomes. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Thirty-four cases were reviewed in this retrospective study for information on clinical presentation, prognostic indicators, survival time and response to various therapies. The most common presenting clinical signs were weight loss, decreased appetite, vomiting, palpable abdominal mass and diarrhoea. Metastatic disease was confirmed in 11 cats. The overall median survival was 97 days. The median survival times for patients who received chemotherapy or had their masses surgically removed was 165 days. Those patients who had an abdominal effusion present at the time of diagnosis survived a median of 30 days. Cats that received non-steroidal anti-inflammatory drug therapy had a median survival of 26 days. This study confirms that exocrine pancreatic carcinoma in cats is an aggressive tumour with a high metastatic rate and poor prognosis, although three patients survived over 1 year. Fifteen percent of the patients were diabetic, which raises the question as to what the link between diabetes and pancreatic cancer in people and cats may be. © 2012 John Wiley & Sons Ltd.

    Full Text Available Introduction: Type 2 diabetes mellitus (DM is a growing problem in our country and we have observed that many patients are associated with thyroid dysfunction later in their life. However, the prevalence of thyroid dysfunction in these patients has not been investigated. Aims and Objectives: To find the prevalence of thyroid dysfunction in type 2 DM in Manipur, India. Materials and Methods: In this retrospective study, data of 202 Type 2 DM patients who attended the diabetic clinic of the Regional Institute of Medical Sciences, Imphal from January 2011 to July 2012, and whose thyroid stimulating hormone (TSH level was investigated were included. The inclusion criteria are known cases of type 2 DM. Exclusion criteria are patients with previous history of hypothyroidism and those on drugs affecting the thyroid profile. Results: Out the 202 type 2 DM patients for the study of which 61 are males and 141 are females, 139 (68.8% are euthyroid, 33 (16.3% have subclinical hypothyroidism (10 males and 23 females, 23 (11.4% have hypothyroidism (6 males and 17 females, 4 (2% have subclinical hyperthyroidism and 3 (1.5% are hyperthyroidism cases. Maximum cases were of hypothyroidism (subclinical and clinical seen in the age group of 45-64 years. Patients with BMI > 25 were at increased risk of having hypothyroidism (P < 0.016. Conclusion: Prevalence of hypothyroidism is quite high in type 2 DM patients above 45 years and more so if their BMI is over 25.

    The aim of this retrospective study was to evaluate the relationship between orthodontic treatment and gingival health. A total of 251 patients among whom 177 were girls and 74 were boys, recruited from the records pool of the Department of Orthodontics, Faculty of Dentistry, University of Gazi, were included in the study. Patients' treatments have been completed by postgraduate students during the period between 2006 and 2012. Patients' folders were analyzed according to their age, treatment time, and the type of orthodontic treatment. Intra-oral photographs were analyzed, and the presence or absence of visible plaque, visible inflammation, and gingival recession were recorded, and incisor inclinations analyzed on lateral cephalometric films, before and after orthodontic treatment. No statistically significant difference was found in patients treated with functional appliances before and after treatment. In patients treated with fixed orthodontic appliances, visible plaque, visible inflammation, and gingival recession showed significant increases after treatment, gingival biotype did not show any significant difference. Positive correlation was found between lower incisor position and gingival recession in patients treated with fixed appliance and extraction. And also cuspids were the teeth with the highest prevalence of gingival recession. Considering the relationship between orthodontic treatment and gingival health, cooperation among patients, orthodontists, and periodontists is important.

    Only a handful of studies have assessed tooth loss risk in chronic periodontitis patients following active therapy and factors associated with it. The aim of this retrospective study was to assess tooth loss in a cohort of chronic periodontitis patients undergoing maintenance care in a UK private practice setting. One hundred chronic periodontitis patients treated with active periodontal therapy were followed up in supportive periodontal therapy (SPT) for at least 5 years. Tooth loss rates and the effect of patient and tooth factors on tooth loss were assessed. Existing patient-based prognosis systems and a novel tooth-based prognosis system were tested for their association with tooth loss. Excluding third molars, 34 teeth were extracted during SPT, with an overall average tooth loss of 0.06 teeth/patient/year (0.02 for periodontal reasons). Multivariable analysis showed that age, patient prognosis based on the Periodontal Risk Assessment system, tooth prognosis, furcation involvement and previous endodontic therapy were significantly associated with tooth loss during SPT. Good overall stability and a small tooth loss rate were observed in this cohort of chronic periodontitis cases under SPT in private practice. Patient-based and tooth-based prognosis systems may be used to estimate the risk of tooth loss. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Introduction. One great challenge in obstetric care is labor inductions. Misoprostol has advantages in being cheap and stable at room temperature and available in resource-poor settings. Material and Methods. Retrospective cohort study of 4002 singleton pregnancies with a gestational age ≥34 w at Sodersjukhuset, Stockholm, during 2009-2010 and 2012-2013. Previously used methods of labor induction were compared with misoprostol given as a solution to drink, every second hour. Main outcome is as follows: Cesarean Section (CS rate, acid-base status in cord blood, Apgar score 1500 ml (PPH. Results. The proportion of CS decreased from 26% to 17% when orally given solution of misoprostol was introduced at the clinic (p<0.001. No significant difference in the frequency of low Apgar score (p=0.3, low aPh in cord blood (p=0.1, or PPH (p=0.4 between the different methods of induction was studied. After adjustment for different risk factor for CS the only method of induction which was associated with CS was dinoproston⁎⁎ (Propess® (aor = 2.9 (1.6–5.2. Conclusion. Induction of labor with misoprostol, given as an oral solution to drink every second hour, gives a low rate of CS, without affecting maternal or fetal outcome.

    Canine mammary sarcomas (CMSs) are rarely diagnosed in female dogs, which explains the scarcity of immunohistochemical findings concerning those tumors. This paper presents the results of a retrospective study into CMSs and discusses the clinical features of the analyzed tumors, the expression of intermediate filaments CK, Vim, Des and α-SMA, and the expression of p63, Ki67, ERα, PR and p53 protein. Four percent of all canine mammary tumors (CMTs) were classified as CMSs, and they represented 5.1% of malignant CMTs. The mean age at diagnosis was 11.1 ± 2.8 years. Large breed dogs were more frequently affected (38.7%). The majority of observed CMSs were fibrosarcomas (2.1%). All CMSs expressed vimentin, and higher levels of vimentin expression were noted in fibrosarcomas and osteosarcomas. Ki67 expression was significantly correlated with the grade of CMS. Our results revealed that CMSs form a heterogeneous group, therefore, immunohistochemical examinations could support differential and final diagnosis. Although this study analyzed a limited number of samples, the reported results can expand our knowledge about CMSs. Further work is required in this field.

    To analyze craniomaxillofacial injuries in selected hospitals in the United Arab Emirates (UAE). This is a retrospective study of craniomaxillofacial injuries treated in 3 major hospitals in the UAE. Patient files were retrieved, reviewed, and analyzed. The main analysis outcome measures were the patients' name, age, and gender and the injuries' time, site, type, treatment and outcome. A total of 288 patients sustained 475 craniomaxillofacial injuries; road traffic accidents caused the majority of injuries. The patients ranged in age from 2 to 82 years (mean, 27.3 years), and the male-to-female ratio was 7:1. The yearly distribution of fractures peaked during 2001, and the monthly distribution peaked in January. The greatest number (41%) of patients were UAE nationals. Most patients (70.5%) had mandibular fractures, and the most common site was the body. There were 139 patients (48.3%) with a total of 171 midface fractures (36%); the most common fracture site was the zygomatic complex (29.8%). The most common treatment for jaw fractures was plating plus intermaxillary fixation. Stable zygomatic complex fractures were closely reduced (elevated), and unstable ones were treated by internal fixation. About 25% of the cases had 1 or more postoperative complication. Craniomaxillofacial injuries in the UAE included in this study are somewhat similar to those reported in other countries. Differences from other countries are probably related to factors peculiar to the UAE, such as climate, social trends, and the cosmopolitan population.

    The aim of this study was to investigate the mechanisms and etiologic factors of forearm nerve injuries. This retrospective survey included all patients treated surgically in Clinical Department of Neurosurgery, Clinical Center of Serbia, from January 1, 2000 to December 31, 2010. All relevant data were collected from medical records. Statistical procedures were done using the PASW 18 statistical package. Our study included 104 patients that underwent surgery after forearm nerve injury. The majority of admitted patients were male (n = 84; 80.8%) and only 20 (19.2%) were female. Ulnar nerve injury predominated with 70 cases, followed by median nerve with 54 (51.9%) cases and radial nerve with only 5 cases. Transection was the dominant mechanism of injury and it occurred in 84.6% of cases. Injury by a sharp object was the most frequent etiologic factor and it occurred in 62 (59.6%) patients, while traffic accident and gunshot injuries were the least common etiologic factor of forearm nerve injury, occurring in 7 (6.7%) and 6 (5.8%) cases, respectively. Associated injuries of muscles and tendons, bones and blood vessels occurred in 20 (19.2%), 16 (15.4%) and 15 (14.4%) patients, respectively. The etiology and mechanism of peripheral nerve injury are of great importance when choosing the right course of treatment in each individual patient because timing and type of treatment are closely related to these factors.

    The aim of this study is to summarize the experience on prenatal diagnosis of Down syndrome. The study includes a retrospective data analysis of 157 prenatally detected cases of Down syndrome, routinely diagnosed among 6448 prenatal investigations performed during a 13-year period (2002-2014) in a single tertiary center. The prevalence of diagnosed Down syndrome cases was 2.4%. Maternal age alone was indication for prenatal diagnosis in 47 cases (45.2%), increased first-/second-trimester biochemical screening test in 34 cases (21.7%), abnormal ultrasound examination in 69 cases (43.9%), positive familial history for chromosomal abnormalities in four cases, and high risk for trisomy 21 revealed by cell-free DNA testing in three cases. Ultrasound anomalies were present in total of 94 fetuses (59.8%). The most common abnormality was cystic hygroma found in 46 cases (29.3%). A regular form of Down syndrome (trisomy 21) was found in 147 cases (93.6%), Robertsonian translocation in six cases (3.8%), and mosaic form in four cases (2.6%). In prenatal diagnosis of Down syndrome noninvasive screening methods are important for estimation of individual risks, in both, young population of woman and older mothers, while conventional and molecular cytogenetic methods are essential for definite diagnosis and proper genetic counseling.

    Oral mucositis (OM) is an adverse side effect among hematopoietic stem cell transplantation (HSCT) recipients. The objective of this retrospective study was to evaluate the preventive effect of photobiomodulation (PBM) applied three times per week versus seven times per week in patients undergoing HSCT. The risk factors related to the incidence and severity of OM were also assessed. This was a retrospective study that evaluated 99 HSCT recipients who received different PBM protocols. Group I received three sessions per week, and group II received daily treatment. PBM was applied using a continuous-wave diode laser (InGaAlP; MM Optics, São Carlos, SP, Brazil) at a wavelength of 660 nm (visible-red) and a total radiant energy of 0.24 J per point. The baseline disease, type of transplant, type of conditioning, prophylaxis against graft-versus-host disease, OM grade, absolute leukocyte and platelet counts, and levels of liver and renal function markers were collected from medical records. The patients' age ranged from 13 to 71 years (mean/SD, 40.54 ± 16.45). No significant difference was observed between groups I and II regarding sex, age, ethnic, diagnosis, donor type, and conditioning treatment. Both PBM protocols were equally efficient in preventing OM (p = 0.34, ANOVA). Independent of the PBM protocol used, patients who received allogeneic transplant (p < 0.01-Fischer's exact test), total body irradiation (TBI-12Gy) (p = 0.01-chi-square test), busulfan + cyclophosphamide (p < 0.01-chi-square test), or methotrexate-containing regimens (p < 0.01-Fischer's exact test) demonstrated higher OM incidence and severity. Myelosuppression (p < 0.01-Mann-Whitney test) and impaired renal function (p = 0.02-Mann-Whitney test) were also considered risk factors for OM. Based on this retrospective data, PBM was effective in preventing OM in patients undergoing HSCT even when it was applied three times a week. A prospective study might be necessary to confirm

    Full Text Available Background: In recent decades, there has been a dramatic increase in the prevalence of multiple pregnancies. An important reason is the increased use of assisted reproductive techniques for conception. Despite the advances in prenatal care, maternal and neonatal morbidity and mortality caused by multiple pregnancies are still high. Aim: This study aimed to evaluate the fetomaternal complications in higher order multiple pregnancies. Design: The design is a retrospective study. Setting: Triplet and quadruplet pregnancies were investigated in this study. Methods: This study investigated the outcome of triplet and quadruplet pregnancies born alive at the Mahdiyeh hospital, Tehran, Iran from 2006 to 2015. Results: In this study, 111 triplet pregnancies and 24 quadruplet pregnancies were studied, 80% of which resulted from assisted reproductive technology. The average age of pregnancy termination was 31 weeks, the average weight of the first to third neonates was 1400 g and the average weight of the fourth neonate was 700 g. The most common reason for early termination of pregnancy was preterm labor, the most maternal complication was uterine atony and the most common neonatal complication was pre-maturity and then respiratory distress syndrome (RDS. The mean age of mother in triplets’ deliveries was significantly lower than in the quadruplets. The average weight of the first to third neonates, the average of 1st and 5th minutes Apgar score of the first neonates and the average gestational age of termination for the first and second neonates in triplets was significantly higher than in the quadruplets. Hospitalization due to preterm labor in quadruplets’ delivery was significantly higher than in triplets. Conclusion: Higher order multiple pregnancies are associated with higher maternal and neonatal complications. Mothers with such pregnancies needs more care in the prenatal period, during labor and in the postpartum period, and also their

    Full Text Available A retrospective study of the epidemiological and clinic-pathological aspects of cattle and buffaloes with degenerative joint disease (DJD was conducted in the state of Pará, Brazil. From 1999 to 2014, eleven cattle and 24 buffaloes were evaluated. All the treated animals with suspected DJD underwent a clinical examination of the musculoskeletal system. In seven cattle and eight buffaloes with clinical signs of the disease postmortem examination was performed. The common clinical signs observed in both species were chronic lameness, stiff gait, postural changes, audible crackles in the affected limb, prolonged recumbency, difficulty in getting up and progressive weight loss. The lesions observed at necropsy were: irregular articular surfaces, erosion of the articular cartilage and the underlying bone tissue, and proliferation of the periarticular bone tissue with formation of osteophytes. The most affected joints in cattle and buffaloes wereof the hind limb. In buffaloes, the main predisposing factor to the onset of DJD was phosphorus deficiency. In cattle, defects of the anatomical conformation of the hind limbs, chronic trauma due to the activities performed, such as semen collection, and advanced age possibly contributed to the emergence of the disease.

    Full Text Available BACKGROUND Electroconvulsive Therapy (ECT among adolescent psychiatric patient is rarely used and studies in this regard are also rare, while its need is of great importance. Aim of this study was to study the prevalence of ECT in common psychiatric illnesses among adolescent age group, where it is indicated and outcome of ECT in those psychiatric patients. MATERIALS AND METHODS All data were collected retrospectively from the chart review for those adolescents aged between 12 to 18 years who received ECT during the period of 2008 - 2012. During the study period a total of 554 patients received ECT, among whom 104 were adolescents. RESULTS Adolescent patients were 18.77% in the whole ECT sample; the average age of the adolescents was 16.33 years and number of patients were more with older age. Among all the patients, 48.08% had positive family history of mental illness and 81.73% were from lower Socioeconomic Class. The use of ECT was more with schizophrenia (n= 63, 60.57% and acute and transient psychotic disorder (n= 30, 28.85%. The most common indication was agitation and aggression (n= 29, 27.88% followed by poor medication response (n= 19, 18.27%. Good response is found in most of the cases (n= 88, 84.62%, only a few percentage of cases showed minor and transient adverse event. CONCLUSION The result of our study suggests that prevalence of ECT among adolescent psychiatric patients is quite high and ECT is a safe and effective method of treatment in the adolescent psychiatric patients, especially those patients who are severely ill and poorly responding to medication.

    Background & objectives: A retrospective study on chikungunya outbreak in India in five States viz. Delhi, Madhya Pradesh, Orissa, Maharashtra and Kerala was conducted in 2007-2008 to know the distribution and determinants of chikungunya fever outbreak in India. Methods: On the basis of high and low incidence of chikungunya fever, two districts from each State and two wards from the selected district were taken for random selection of 1000 households from 10 districts and 5 States. Semi-structured questionnaires were administered to individuals, patients, qualified health professionals and to stakeholders for collecting information. Results: The educational background and occupation of the respondents showed variations across the study States. Only in high incidence ward of Maharashtra, water storage period for 3-6 days and emptying, drying of water containers on weekly basis was noted. The study through knowledge, attitude, belief, practice (KABP) obtained individual's perception of chikungunya fever, its prevention and control. Patients’ expenditure on treatment was mainly recorded less than Rs 500 across study States. Health facility survey obtained an overview of the capacity of local health facilities. Stakeholders’ perception regarding chikungunya fever was also noted. Interpretation & Conclusions: The study revealed differences in awareness of chikungunya, cause of the disease, vector responsible, mode of transmission, biting time and elimination of breeding of mosquitoes statistically significant among high and low incidence wards of all the States. Expenditure on treatment was independent of economically active status and loss of man-days across all the States. Education and occupation did not have any relation with emptying/drying of water containers in high incidence wards. Strengthening of surveillance, information, education and communication (IEC) activities along with case management facilities may be provided by the State health department for

    Dental implant insertion for oral rehabilitation is a worldwide procedure for healthy and medically compromised patients. The impact of systemic disease risks on the outcome of implant therapy is unclear, since there are few if any published randomized controlled trials (RCTs). The objective of this study is to investigate the rate of complications and failures following dental implantation in medically compromised patients in order to elucidate risk factors and prevent them. A retrospective cohort study was conducted from patient files treated with dental implantation between the years 2008-2014. The study group consisted of medically complex patients while the control group consisted of healthy patients. Preoperative, intraoperative, and post operative clinical details were retrieved from patients' files. The survival rate and the success rate of the dental implants were evaluated clinically and radiographically. A total of 204 patients (1003 dental implants) were included in the research, in the study group, 93 patients with 528 dental implants and in the control group, 111 patients with 475 dental implants. No significant differences were found between the groups regarding implant failures or complications. The failure rate of dental implants among the patients was 11.8 % in the study group and 16.2 % in the control group (P = 0.04). It was found that patients with a higher number of implants (mean 6.8) had failures compared with patients with a lower number of implants (mean 4.2) regardless of their health status (P dental implantation in medically complex patients and in healthy patients. Medically complex patients can undergo dental implantation. There are similar rates of complications and failures of dental implants in medically complex patients and in healthy patients.

    Full Text Available Background/Aims: Open reduction and internal fixation (ORIF is a standard surgical procedure in jaw trauma and in orthognathic surgery. Insertion of screws is a significant risk for accidental tooth root injury with varying outcomes. Contrary evidences are found in literature due to a variety of study designs. This study was undertaken to address the lacunae and possibly estimate the difference in occurrence of tooth damage during or after ORIF between trauma and planned osteotomies. Materials and Methods: In this retrospective study, the data of ORIF in either trauma or orthognathic surgery fulfilling inclusion and exclusion criteria were collected and analyzed. Results: There were 1632 patients fulfilling the inclusion and exclusion criteria and formed the study group, of which 663 were in orthognathic surgery, of whom 210 had bimaxillary orthognathic surgery. In the trauma group, 358 patients had fractures involving both jaws whereas 272 had maxilla alone and 339 had mandibular fractures alone. On comparing the outcome, of the 9073 screws studied, 93.40% were not involved in any contact with the teeth, 6.3% were in category of potential hits (near apices or the root surfaces, and only 0.28% had evidence of root damage with the screws. It is observed that molar and premolar had a significant difference in terms of the type of surgery (P ≤ 0.05 whereas canine (P = 0.75 and incisor (P = 0.67 showed no statistical difference. Conclusion: ORIF when used as mentioned is a safe way for the management of fractures. The incidence of root injury is not uncommon but can be avoided with careful planning and execution.

    OBJECTIVE Determine the coverage rate of syphilis testing during prenatal care and the prevalence of syphilis in pregnant women in Brazil. METHODS This is a national hospital-based cohort study conducted in Brazil with 23,894 postpartum women between 2011 and 2012. Data were obtained using interviews with postpartum women, hospital records, and prenatal care cards. All postpartum women with a reactive serological test result recorded in the prenatal care card or syphilis diagnosis during hospitalization for childbirth were considered cases of syphilis in pregnancy. The Chi-square test was used for determining the disease prevalence and testing coverage rate by region of residence, self-reported skin color, maternal age, and type of prenatal and child delivery care units. RESULTS Prenatal care covered 98.7% postpartum women. Syphilis testing coverage rate was 89.1% (one test) and 41.2% (two tests), and syphilis prevalence in pregnancy was 1.02% (95%CI 0.84;1.25). A lower prenatal coverage rate was observed among women in the North region, indigenous women, those with less education, and those who received prenatal care in public health care units. A lower testing coverage rate was observed among residents in the North, Northeast, and Midwest regions, among younger and non-white skin-color women, among those with lower education, and those who received prenatal care in public health care units. An increased prevalence of syphilis was observed among women with social inequalities in access to health care units, coupled with other gaps in health assistance, have led to the persistence of congenital syphilis as a major public health problem in Brazil.

    One day session linear accelerator based stereotactic radiosurgery of intraocular malignant melanoma is a method of "conservative" attitude to treat posterior uveal melanoma. Retrospective clinic-based study of patients with posterior uveal melanoma in stage T2/T3 who underwent stereotactic radiosurgery at linear accelerator in period 2001-2011. Immobilization of the affected eye was achieved by mechanical fixation to the stereotactic Leibinger frame. The stereotactic treatment planning after fusion of computed tomography and magnetic resonance imaging was optimized according to the critical structures (lenses, optic nerves, chiasm). In group of 96 patients with posterior uveal melanoma treated with one day session stereotactic radiosurgery, patient age ranged from 25 to 80 years with a median of 54 years. Median tumor volume at baseline was 0.6 cm(3) (with range from 0.2 to 1.0 cm(3)). Median maximal dose applied was 49.0 Gy (range from 37.0 to 52.0 Gy). Secondary enucleation was necessary in 11 patients (11.5%) due to complications like irradiation neuropathy and secondary glaucoma. Tumor local control was successful in 95% of patients in 3 years interval after stereotactic radiosurgery and in 85% of patients in 5 years interval after stereotactic radiosurgery. One step LINAC based stereotactic radiosurgery with a single dose 35.0 Gy is one of treatment options to treat T2 or T3 stage posterior uveal melanoma.

    Upper limb amputation causes a severe permanent disability. Upper limb transplantation is subject to treatment to prevent rejection and influenced by organizational, socioeconomic, psychological, ethical factors. Analysis of the results creates the potential for continuing this work in specific conditions in our country. We retrospectively analyzed data from the literature. Upon completion of documentation (May 2011) there were 74 transplants in 53 patients worldwide. We have studied the available information on the surgical interventions and their results. Upper limb allograft has a complex structure comprising tissue with variable antigenicity. Surgery is performed by a large multidisciplinary team, whose increased experience leads to a shorter length of the operation. The postoperative follow-up and rehabilitation program are standardized, and patients' compliance is essential. The greatest advances have occurred in immunosuppression protocols. The upper limb transplantation was performed in 20 centers of 12 countries so far. The specification of the indications and contraindications, the proper selection of patients, the increasing experience and new immunosuppression protocols provide a higher success rate and quality of functional outcome. By applying these conceptual acquisitions we will be able to create conditions for the integration of our country in this globally convergent scientific effort.

    This is a retrospective study of concussion patient data conducted to analyze the prevalence of somatization in patients presenting with post-concussion symptoms. Patient records from June 2010 to December 2015 were examined for concussion history, psychosocial history, neuropsychological test results, validity scores, and a symptom severity scale. Records meeting inclusion criteria from 33 males and 27 females were located. The sample had an age range of 11-78 years with a mean age of 33.40 (SD +/- 7.5 years). A clinically significant number of patients (55%) were found to be somaticizing their symptoms and a significant majority (78%) of somaticizing patients reported no loss of consciousness, retrograde amnesia, or post-traumatic amnesia but their symptom validity scales were significantly exaggerated. Caution should be exercised by clinicians to ensure that the obtained results of neuropsychological testing are reliable and valid. It is very important for the clinician to take into account the entire patient history, including psychosocial factors (such as pre-existing psychological traits or conditions) and social influences (such as stressors in family dynamics or work/school activities that may be affecting the patient's complaints).

    Foreign bodies are one of the most common ENT (Ear, Nose and Throat) urgencies. Serious complications may occur, like tympanic perforations and bronchoaspiration, but they are uncommon. To analyze a 1356 foreign body series and establish causes for the complications, looking at prevention. 1356 patients with ear, nose and throat foreign bodies from the ENT Department of Souza Aguiar Hospital, in Rio de Janeiro, between 1992 and 2000, were analyzed in a retrospective study for parameters like age, gender, type and localization of the foreign body, time span between introduction and removal of the foreign body and complications. The most common foreign bodies were beans and the most frequent age was between 1 and 4 years old. Ear foreign bodies were the most common, followed by nasal foreign bodies. Complications were statistically related to time, childs age and practical experience of the physician. Most of the situations related to ENT foreign bodies are avoidable. Improvements in Public Health Assistance and otolaryngologists training are essential to avoid serious complications.

    Full Text Available Objective: Herpes zoster is an acute dermatomal viral infection caused by the reactivation of varicella zoster virus. While it is commonly seen among elderly and immunocompromised individuals, it is rare in healthy children. The aim of this study was to evaluate the clinical features, treatment and complications of healthy children with herpes zoster. Methods: Thirty one patients aged between 0-16 years who were admitted to our clinic with the diagnosis of herpes zoster, between January 2014 and December 2014, were evaluated retrospectively for age, gender, month of admission, complaint, history of chickenpox infection or varicella vaccination, triggering factors, dermatomal involvement, complications and treatment. Results: Among 31 patients with diagnosis of herpes zoster, 19 were boys (61.3% and 12 were girls (38.7%. The mean of age was 9.12±4.4 years. Twenty patients had thoracic (64.5%, six had lumbar (19.4% and five had cervical involvements (16.2%. The most frequent symptoms were pruritus and pain, respectively. Six patients were administered topical treatment and 25 patients were treated with both systemic and topical treatments. Complication was not observed. Conclusion: Herpes zoster is also being encountered increasingly in healthy children nowadays. It is benign and generally no complications are observed. Incidence can vary because of geographic and socioeconomic differences like vaccination programs.

    Wisdom tooth transplants offer youth the possibility of biologically fixed tooth replacement in cases of premolar agenesis or premature loss of a molar. In the present study, 57 transplants of third molars were reviewed and evaluated retrospectively on preoperative findings (root growth stages, extraction sites, indication for transplantation), on postoperative clinical findings (local gingivitis, periodontal probing values, tooth mobility, percussion sound and percussion pain) and on radiological findings (tertiary build-up of dentin, osseous periradicular conditions, progress of root growth). Only the transplants which healed with a vital pulp and in a periodontally healthy state were considered successful. Upper and lower wisdom teeth having 50% to 75% root growth progression were transplanted. The postoperative follow-up observation period averaged 26.4 months. The success of a wisdom tooth transplantation was not influenced by the root growth stage (p = 1), the extraction location of wisdom teeth (p = 0.45), or the feasibility for a transplantation (p = 0.56). Three teeth showed pulpal necrosis with apical periodontitis and were counted as failures. The success rate was rather high with 54 out of 57 transplants (94.7%), therefore wisdom tooth transplantations, with careful selection of a suitable graft and its gentle removal, can be described as a good predictable treatment.

    To describe the clinical and radiological characteristics of patients with Stafne bone cavity. A retrospective, observational study of 11 cases of Stafne bone cavity. After finding an imagine compatible with Stafne bone cavity in the Orthopantomograph(r) of 11 patients, a sialography of the mandibular gland was made in 3 cases, computerized tomography (CT) in 6 cases, and in 4 cases surgical intervention to confirm the diagnosis. The average age was 51.5 years, predominantly males. The entity was diagnosed incidentally during a routine radiology in all cases. The sialography revealed glandular tissue within the defect, and the CT demonstrated the conservation of the lingual cortical and the peripheral origin of the lesion. Glandular tissue was found within the lesions of two of the patients who underwent surgery, and in the other two the cavity was empty. No progressive changes were found in any of the 11 cases. Stafne bone cavity was an incidental finding, presenting no evolutionary changes, and as such conservatory therapy based on periodic controls was indicated. Currently, complementary techniques such as CT are sufficient to establish a certain diagnosis.

    2011-01-01

    We performed this retrospective case-control study analyzing 428 first-attempt in vitro fertilization (IVF) cycles, among which 254 involved women with a previous or present diagnosis of ovarian endometriosis. First, the results of these 254 cycles were compared with 174 cycles involving patients with proven non-endometriotic tubal infertility having similar age and body mass index. Women with ovarian endometriosis had a significantly higher cancellation rate, but similar pregnancy, implantation and delivery rates as patients with tubal infertility. Second, among the women with ovarian endometriosis, the women with a history of laparoscopic surgery for ovarian endometriomas prior to IVF and no visual endometriosis at ovum pick-up (n = 112) were compared with the non-operated women and visual endometriomas at ovum pick-up (n = 142). Patients who underwent ovarian surgery before IVF had significantly shorter period, lower antral follicle count and required higher gonadotropin doses than patients with non-operated endometriomas. The two groups of women with a previous or present ovarian endometriosis did, however, have similar pregnancy, implantation and live birth rates. In conclusion, ovarian endometriosis does not reduce IVF outcome compared with tubal factor. Furthermore, laparoscopic removal of endometriomas does not improve IVF results, but may cause a decrease of ovarian responsiveness to gonadotropins. PMID:21679474

It was possible to establish 141 specific orthopedic diagnoses in 1955 horses with lameness. In 14.58 % horses, multiple pathologic orthopedic changes were determined. In 61.84 % cases, the pathologic changes were present on the thoracic limb, 28,86 % on the pelvic limb and other parts of the oganism (neck, spine, muscles in 9.29 % cases. Pathologic changes on the tendons, ligaments, tendon sheats, bursae and muscles were determined in 31.51 % cases. Diseases of the hoof were present in 25.82 % cases. According to our investigation the most frequent orthopedic diseases are: podarthritis (acute, chronic, septic (5.04 %, navicular disease (4.69 %, tendinitis m. flexor digitalis superfacialis (4.51 %, kissing spine syndrom (4.30 % periarthritis et osteoarthrosis tarsi (3.30 %, distal metacarpal/metatarzophalengeal tendovaginitis (3.30 % and high suspensory ligament desmitis (3.12 %. Most frequent fractures were diagnosed on the metacarpal/metatarsal bone II and IV (2.56 %. Osteochondrossis dissecans was most frequently determined in the tarsocrural (1.26 % and the metacarpophalengeal joint (1.56 %.

    This 5-year retrospective study reports 54 patients with infection, caused by Streptococcus canis, a pyogenic Lancefield group G streptococcus initially isolated from various animal sources. During 1997-2002, Streptococcus canis accounted for 1% of all streptococci isolated. The clinical signs, outcome and bacteriological characteristics were reviewed. All except eight were symptomatic. Clinical manifestations were: soft tissue infection (n=35), bacteremia (n=5), urinary infection (n=3), bone infection (n=2) and pneumonia (n=1). The course was favorable in 52 cases while two died from sepsis. Cultures were often polymicrobial (n=42, 77.8%) apart from hemocultures. The isolates were sensitive to most antibiotics. Presence of the bacteria did not always signify infection owing to the possible occurrence of colonization. The frequency of S. canis infections is rare and likely underestimated owing to the fact that streptococci are sought only on the basis of the Lancefield classification. The search for S. canis is recommended whenever patients present with symptoms evocative of exposure to a potentially contaminated animal.

    Rocky Mountain spotted fever (RMSF), a lethal tick-borne illness, is prevalent in the south central United States. Children younger than 10 years old have the greatest risk of fatal outcome from RMSF. The objective of the current study was to review pediatric cases of RMSF seen in the dermatology consult service and to evaluate dermatology's role in the diagnosis and management of this disease. A retrospective review was performed of inpatient dermatology consultations at a tertiary care center in North Carolina from 2001 to 2011. Data collected included patient demographic characteristics, symptoms, pre- and postconsultation diagnoses, diagnostic procedures, length of hospital stay, and outcome. A total of 3,912 consultations were conducted in the dermatology service over 10 years. Six patients with RMSF, ranging in age from 22 months to 10 years (mean 5.1 years), were evaluated during April, May, and June. All preconsultation diagnoses included RMSF in the differential diagnosis. All patients underwent skin biopsies, and a culture was obtained in one case. Fifty percent of patients died within 4 days of hospitalization. Variables associated with mortality from RMSF are delayed diagnosis and initiation of antirickettsial therapy. Physicians should consider RMSF in children presenting with fever and rash during the summer months. Dermatology consultation is useful in evaluating patients with suspicious clinical features of RMSF with skin findings. © 2016 Wiley Periodicals, Inc.

    Full Text Available This was a retrospective review of a consecutive series of patients with spinal disease in year 2000, who underwent posterior fusion and instrumentation with Harrington distraction and Cotrel-Dobousset system to evaluate causes of hardware failure. Many cases of clinical failure has been observed in spinal instrumentation used in spinal disorder like spondylolisthesis, fractures, deformities, … . Thirty six cases that were operated because of spinal disorders like spondylolisthesis, fractures, deformities, …, were included in this study. Seventeen of this cases had breakage of device. Factors like age at surgery, type of instrumentation, angles before and after surgery and …, were compared in two groups of patients. The most common instrument breakage was pedicle screw breakage. Pseudoarthrosis was the main factor that was presented in failure group (P value<0.001. Other important causes were, age of patient at surgery (P value=0.04, pedicle screw placement off center in the sagittal or coronal plane of the pedicle (P value=0.04. Instrumentation loads increased significantly as a direct result of variations in surgical technique that produce pseudoarthrosis, pedicle screw placement off center in the sagittal plane of the pedicle, or using less than 6 mm diameter screw. This factor can be prevented with meticulous surgical technique and using proper devices.

    Full Text Available   Introduction: To assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   Materials and Methods: A retrospective study on 46 patients (26 males and 20 females who were referred to the Razavi Hospital from April 2009 to May 2012 with massive hemoptysis and had bronchial artery embolization procedures. General characteristics of the patients including age, gender, etiology, and thorax computed tomograms, findings of bronchial angiographic, results of the embolization, complications related to bronchial artery embolization and clinical outcome during follow-up were reviewed. Results: The etiology included previous pulmonary tuberculosis in 20 cases, previous tuberculosis with bronchiectasis in 16 cases, bronchiectasis in 6 cases, and active pulmonary tuberculosis in one case. No identifiable causes could be detected in three patients. Moreover, massive hemoptysis was successfully and immediately controlled following the embolization procedure in all patients. One patient developed recurrent hemoptysis during one month following the procedure and was treated by re-embolization. No major procedure–related complication such as bronchial infarction was identified However none of the patientsexperienced neurological complications. Conclusion: Bronchial artery embolization is a safe and effective means of controlling massive hemoptysis and should be regarded as the first-line treatment for this condition.

    Immunosuppressive regimens in renal transplantation frequently contain corticosteroids, but many centers withdraw steroids as a consequence of unwanted side effects of steroids. The optimal timing to withdraw steroids after transplantation, however, remains unclear. The aim of this study was to determine an optimal time point following kidney transplantation that is associated with reduced mortality without jeopardizing the allograft to allow safe discontinuation of steroids. We conducted a retrospective cohort study and computed a concatenated landmark-stratified Cox supermodel to estimate hazard ratios and 95% confidence intervals for mortality and graft loss using dynamic propensity score matching to adjust for confounding by indication. A total of 6070 first kidney transplant recipients in the Austrian Dialysis and Transplant Registry who were transplanted between 1990 and 2012 were evaluated and classified according to steroid treatment status throughout follow-up after kidney transplantation; 2142 patients were withdrawn from steroids during the study period. Overall, 1131 patients lost their graft and 821 patients in the study cohort died. Steroid withdrawal within 18 months after transplantation was associated with an increased rate of graft loss compared to steroid maintenance during that time (6 months after transplantation: HR = 1.8; 95% CI, 1.3 to 2.6; 18 months after transplantation: HR = 1.3; 95% CI, 1.1 to 1.6; 24 months after transplantation: HR = 1.2; 95% CI, 0.9 to 1.5), while mortality was not different between groups. Our findings suggest that steroid withdrawal after anti-IL-2 induction in the first 18 months after transplantation is associated with an increased risk of allograft loss.

    The purpose of the study is to evaluate the extent to which a retrospectively conducted translatability assessment (TA) could identify the items previously singled out during the validation study as having poor content validity or poor measurement performance. This study was performed with the intent of supporting evidence of the usefulness of TA early in the PRO development process. The Weight module of the Youth Quality-of-Life Instrument (YQOL-W) was used for this appraisal of translatability. Two linguists, blinded to the design and results of content validation and psychometric analyses, conducted a TA on the 32-item version of the YQOL-W taken into cross-sectional validation for item reduction. TA results were categorized into (1) issues relating to target culture (cross-cultural issues) and (2) issues relating to the structure of the original questionnaire (structural issues). Items for possible revision or deletion were identified. We compared the results of the TA with the content validity and psychometric results and decisions to eliminate items after cross-sectional validation. Content validation identified seven of the 32 items to be dropped, and psychometric analyses including the 25 remaining items highlighted an additional four to be eliminated, yielding a final instrument with 21 items. Out of these 11 dropped items, TA had identified nine as problematic (82 %) and the developer was advised to drop five of them (45.4 %). In addition, TA results highlighted the need to change the original formulation of eight items for semantic reasons and identified two instances where alternative wording should be used for translation purposes without any change to the original formulation. Our study showed that translatability assessment confirmed problematic issues in items previously identified as having poor content validity or poor measurement performance. In general, a translatability assessment offers the possibility for the identification of alternative

    The immune and inflammatory pathways involved in psoriasis could favor the development of atherosclerosis, consequently increasing mortality. The objectives of this study were: 1) to assess the mortality of a population with psoriasis compared to a control group, and 2) to assess the prevalence of cardiovascular risk factors. A retrospective cohort was analyzed from a secondary database (electronic medical record). All patients with a diagnosis of psoriasis at 1-01-2010 were included in the study and compared to a control group of the same health system, selected randomly (1:1). Subjects with a history of cardiovascular disease were excluded from the study. A survival analysis was performed considering death from any cause as an event. Follow-up was extended until 30-06-2015. We included 1,481 subjects with psoriasis and 1,500 controls. Prevalence of cardiovascular risk factors was higher in the group with psoriasis. The average follow-up time was 4.6±1.7 years. Mortality was higher in psoriasis patients compared to controls (15.1 vs. 9.6 events per 1,000 person-year, P<.005). Psoriasis was seen to be significantly associated with increased mortality rates compared to the control group in the univariate analysis (HR 1.58, 95% CI 1.16-2.15, P=.004) and after adjusting for cardiovascular risk factors (HR 1.48, 95% CI 1.08-2.3, P=.014). In this population, patients with psoriasis showed a higher prevalence for the onset of cardiovascular risk factors as well as higher mortality rates during follow-up.

    Full Text Available Pemphigoid gestationis (PG is a rare autoimmune bullous dermatosis of pregnancy usually presents in the second or third trimester. It is characterized by pruritic, urticarial plaques with the development of tense vesicles and bullae within the lesions. Pathogenesis of PG is not fully established, however, most patients develop circulating autoantibodies targeting the bullous pemphigoid (BP 180 antigen. The aim of this work is to draw a profile of the epidemiology, clinical aspects, treatment and evolution of the disease by studying hospital series. We retrospectively investigated the 13 patients who were diagnosed with PG based on hospital data at the Referral Center of Southwest Iran located in Ahvaz city between March 2002 and March 2011. The age of onset was 21 to 40 years (mean age: 27.5 years. The onset of the disease occurred in the second trimester of pregnancy in 6 patients and in the third trimester of pregnancy in 4 patients. One patient had a flare up of disease during the first trimester and two out of cases in puerperium period. In all cases, pruritus was the first symptom, followed by an erythematous vesiculobullous eruption.  The diagnosis of PG was confirmed by skin biopsy. Ten out of the patients treated with oral corticosteroids (0.5-1 mg/kg/day, one of the patients underwent oral corticosteroids plus topical glucocorticoid and the last patient treated with topical glucocorticoid. PG remains a rare dermatosis of pregnancy. Our series had two particularities compared to other studies: high frequency in primigravida and the frequent involvement of the face. Additionally our study demonstrated that improvement could occur faster and provide acceptable management if the treatment of the patients would be implemented sooner.

    Full Text Available Background: Neonatal pneumoperitoneum is attributed, in most of the reported cases, to necrotising enterocolitis (NEC. There are also other causes leading to free intraperitoneal air. The aim of this study is to describe the clinical spectrum, causes, management and outcome of neonates admitted with pneumoperitoneum in the paediatric surgery unit of a university hospital. Subjects and Methods: This retrospective study included neonates having radiographic evidences of pneumoperitoneum from 2012 to the end of 2014. Patients′ files were analysed regarding age at admission, birth weight, history, clinical picture, management, operative findings and subsequent outcome. Results: Fifty-six out of 379 neonates (14.7% were found to have pneumoperitoneum during the study period. There were 35 males (62.5% and 21 females (37.5%. Cases diagnosed as NEC represented 27 neonates (48.2%. There were 29 cases (51.8% with causes not related to NEC. Non-NEC causes were spontaneous intestinal perforation (8.9%, ano-rectal malformations (7.1%, Hirschsprung′s disease (14.2%, ileal atresia (3.5%, incarcerated inguinal hernia (1.7%, gastric perforation (1.7% and meconium ileus (1.7%. In seven patients (12.5%, those who were managed conservatively (8.9% or whose laparotomy was negative (3.6%, no cause of pneumoperitoneum could be reached. Overall mortality was 25%, 78.5% of which was NEC-related. Conclusions: Neonatal pneumoperitoneum is an alerting finding for paediatric surgeons. Most cases imply serious causes with a significant morbidity and mortality, NEC being the most common cause. On the other hand, pneumoperitoneum is not an absolute indication for surgery. Careful assessment and tailored management can limit the morbidity of unnecessary laparotomies.

    Introduction Obstructive sleep apnea (OSA) is characterized by partial or complete recurrent upper airway obstruction during sleep. OSA brings many adverse consequences, such as hypertension, obesity, diabetes mellitus, cardiac and encephalic alterations, behavioral, among others, resulting in a significant source of public health care by generating a high financial and social impact. The importance of this assessment proves to be useful, because the incidence of patients with comorbidities associated with AOS has been increasing consistently and presents significant influence in natural disease history. Objective The objective of this study is to assess major comorbidities associated with obstructive sleep apnea (OSA) and prevalence in a group of patients diagnosed clinically and polysomnographically with OSA. Methods This is a retrospective study of 100 charts from patients previously diagnosed with OSA in our service between October 2010 and January 2013. Results We evaluated 100 patients with OSA (84 men and 16 women) with a mean age of 50.05 years (range 19–75 years). The prevalence of comorbidities were hypertension (39%), obesity (34%), depression (19%), gastroesophageal reflux disease (GERD) (18%), diabetes mellitus (15%), hypercholesterolemia (10%), asthma (4%), and no comorbidities (33%). Comorbidities occurred in 56.2% patients diagnosed with mild OSA, 67.6% with moderate OSA, and 70% of patients with severe OSA. Conclusion According to the current literature data and the values obtained in our paper, we can correlate through expressive values obesity with OSA and their apnea hypopnea index (AHI) values. However, despite significant prevalence of OSA with other comorbidities, our study could not render expressive significance values able to justify their correlations. PMID:27096019

    Full Text Available Since bat rabies surveillance was first implemented in France in 1989, 48 autochthonous rabies cases without human contamination have been reported using routine diagnosis methods. In this retrospective study, data on bats submitted for rabies testing were analysed in order to better understand the epidemiology of EBLV-1 in bats in France and to investigate some epidemiological trends. Of the 3176 bats submitted for rabies diagnosis from 1989 to 2013, 1.96% (48/2447 analysed were diagnosed positive. Among the twelve recognised virus species within the Lyssavirus genus, two species were isolated in France. 47 positive bats were morphologically identified as Eptesicus serotinus and were shown to be infected by both the EBLV-1a and the EBLV-1b lineages. Isolation of BBLV in Myotis nattereri was reported once in the north-east of France in 2012. The phylogenetic characterisation of all 47 French EBLV-1 isolates sampled between 1989 and 2013 and the French BBLV sample against 21 referenced partial nucleoprotein sequences confirmed the low genetic diversity of EBLV-1 despite its extensive geographical range. Statistical analysis performed on the serotine bat data collected from 1989 to 2013 showed seasonal variation of rabies occurrence with a significantly higher proportion of positive samples detected during the autumn compared to the spring and the summer period (34% of positive bats detected in autumn, 15% in summer, 13% in spring and 12% in winter. In this study, we have provided the details of the geographical distribution of EBLV-1a in the south-west of France and the north-south division of EBLV-1b with its subdivisions into three phylogenetic groups: group B1 in the north-west, group B2 in the centre and group B3 in the north-east of France.

    Full Text Available Virechana (therapeutic purgation is a common procedure that is widely practiced among the panchakarma treatments (pentad treatments. Various Virechaka dravyas (purgative drugs have been described for Virechana. Even after critical analysis of Virechaka dravyas in the literature, still there is difficulty in the fixation of dose. Hence, the retrospective analysis of varied outcomes of Virechana with Danti (Baliospermum montanum avaleha (linctus is discussed in this paper. The study included twenty-seven case reports of patients who were administered Virechana with Danti avaleha. These case reports are of patients suffering from various ailments such as irregular menstrual cycles, polycystic ovarian syndrome, primary and secondary infertility, and psoriasis. Danti avaleha was administered at dose of 10 g and 5 g in the Krura (~strong and Madhyama (~moderate/normal Koshta (~GI tract patients, respectively. Among seven Krura koshta patients, three of them resulted with Pravara (excellent Shuddhi and other four resulted with Madhyama (medium Shuddhi. In twenty Madhyama koshta patients, sixteen of them resulted with avara (minimum Shuddhi and remaining four patients resulted with Madhyama shuddhi. Complications like Udara shoola (spasmodic pain of abdomen and Vamana (emesis were observed during Virechana. Majority of the patients suffered with Udara shoola were of Madhyama koshta. Vamana was seen in both Krura and Madhyama koshta patients. Irrespective of the type of Shuddhi and complications, all the patients resulted with Samyak Kaphaantiki Virikta lakshana (signs of perfect purgation with end expulsion of Kapha. The study concluded that the Krura koshta patients were tolerable for dose of 10 g and are expected to attain Pravara Shuddhi. Whereas Madhyama koshta patients were intolerable even to mild dose of 5 g, producing Avara shuddhi.

    Nuclear protein of the testis (NUT) carcinoma (formerly NUT midline carcinoma) is an aggressive tumor defined by the presence of NUT rearrangement with a poor prognosis. This rare cancer is underdiagnosed and poorly treated. The primary objective of this study was to describe the clinical, radiologic, and biological features of NUT carcinoma. The secondary objective was to describe the various treatments and assess their efficacy. This retrospective multicenter study was based on review of the medical records of children and adults with NUT carcinoma with specific rearrangement or positive anti-NUT nuclear staining (>50%). This series of 12 patients had a median age of 18.1 years (ranges: 12.3-49.7 years). The primary tumor was located in the chest in eight patients, the head and neck in three patients, and one patient had a multifocal tumor. Nine patients presented regional lymph node involvement and eight distant metastases. One-half of patients were initially misdiagnosed. Specific NUT antibody was positive in all cases tested. A transient response to chemotherapy was observed in four of 11 patients. Only two patients were treated by surgery and five received radiotherapy with curative intent. At the end of follow-up, only one patient was still in remission more than 12 years after the diagnosis. Median overall survival was 4.7 months (95% confidence interval [CI]: 2.1-17.7). NUT carcinoma is an aggressive disease refractory to conventional therapy. Early diagnosis by NUT-specific antibody immunostaining in cases of undifferentiated or poorly differentiated carcinoma to identify the specific rearrangement of NUT gene is useful to propose the optimal therapeutic strategy. © 2017 Wiley Periodicals, Inc.

    To assess the success rate of vaginal delivery among women with twin pregnancies; the Twin Birth Study has shown that vaginal delivery and caesarean section are equally safe for twin delivery but >40% of the planned vaginal delivery group delivered by caesarean section. A retrospective cohort study. A tertiary medical centre. A total of 2194 women with twin pregnancies not complicated with very low birthweight. Planned mode of delivery was documented in the woman's electronic record upon entering the delivery room. Information regarding maternal age at delivery, parity, gestational age, presentation, previous history of caesarean delivery, birthweight and Apgar score was collected from the obstetric electronic charts. Rate of vaginal twin delivery. Of the 2194 women included, 1311 twin pregnancies had planned caesarean delivery and 883 underwent a trial of labour. Of the 883 women who underwent a trial of labour, the rate of vaginal delivery was 86.9%, whereas the rates of caesarean delivery and combined vaginal-caesarean delivery were 11.1% and 2.0%, respectively. Presentation of second twin, gestational age and maternal age did affect the chances of success. Nulliparity [odds ratio (OR) 2.38, 95% confidence interval (95% CI) 1.4-4.05], Foley induction of labour (OR 2.33, 95% CI 1.38-3.91) and body mass index >30 kg/m(2) (OR 1.76, 95% CI 1.03-3) were independent risk factors for caesarean delivery. The rate of vaginal delivery among women with twin pregnancies who undergo labour can be high, especially in women who laboured spontaneously and have delivered before. The rate of vaginal delivery of twins can be high, especially in women who have delivered before. © 2015 Royal College of Obstetricians and Gynaecologists.

    To investigate whether plagiarism is more prevalent in publications retracted from the medical literature when first authors are affiliated with lower-income countries versus higher-income countries. Secondary objectives included investigating other factors associated with plagiarism (e.g., national language of the first author's country affiliation, publication type, journal ranking). Systematic, controlled, retrospective, bibliometric study. Retracted publications dataset in MEDLINE (search filters: English, human, January 1966-February 2008). Retracted misconduct publications were classified according to the first author's country affiliation, country income level, and country national language, publication type, and ranking of the publishing journal. Standardised definitions and data collection tools were used; data were analysed (odds ratio [OR], 95% confidence limits [CL], chi-squared tests) by an independent academic statistician. Of the 213 retracted misconduct publications, 41.8% (89/213) were retracted for plagiarism, 52.1% (111/213) for falsification/fabrication, 2.3% (5/213) for author disputes, 2.3% (5/213) for ethical issues, and 1.4% (3/213) for unknown reasons. The OR (95% CL) of plagiarism retractions (other misconduct retractions as reference) were higher (P 1 retraction) with publications retracted for plagiarism (11.5%, 9/78) than other types of misconduct (28.9%, 24/83). This is the first study to demonstrate that publications retracted for plagiarism are significantly associated with first authors affiliated with lower-income countries. These findings have implications for developing appropriate evidence-based strategies and allocation of resources to help mitigate plagiarism misconduct.

    To assess the effectiveness of bracing in adult with scoliosis. Retrospective cohort study. Outpatients followed in 2 tertiary care hospitals. Adults (N=38) with nonoperated progressive idiopathic or degenerative scoliosis treated by custom-molded lumbar-sacral orthoses, with a minimum follow-up time of 10 years before bracing and 5 years after bracing. Progression was defined as a variation in Cobb angle ≥10° between the first and the last radiograph before bracing. The brace was prescribed to be worn for a minimum of 6h/d. Not applicable. Rate of progression of the Cobb angle before and after bracing measured on upright 3-ft full-spine radiographs. At the moment of bracing, the mean age was 61.3±8.2 years, and the mean Cobb angle was 49.6°±17.7°. The mean follow-up time was 22.0±11.1 years before bracing and 8.7±3.3 years after bracing. For both types of scoliosis, the rate of progression decreased from 1.28°±.79°/y before to .21°±.43°/y after bracing (Pscoliosis, it dropped from 1.47°±.83°/y before to .24°±.43°/y after bracing (Pscoliosis. Further prospective studies are needed to confirm these results. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

    Since bat rabies surveillance was first implemented in France in 1989, 48 autochthonous rabies cases without human contamination have been reported using routine diagnosis methods. In this retrospective study, data on bats submitted for rabies testing were analysed in order to better understand the epidemiology of EBLV-1 in bats in France and to investigate some epidemiological trends. Of the 3176 bats submitted for rabies diagnosis from 1989 to 2013, 1.96% (48/2447 analysed) were diagnosed positive. Among the twelve recognised virus species within the Lyssavirus genus, two species were isolated in France. 47 positive bats were morphologically identified as Eptesicus serotinus and were shown to be infected by both the EBLV-1a and the EBLV-1b lineages. Isolation of BBLV in Myotis nattereri was reported once in the north-east of France in 2012. The phylogenetic characterisation of all 47 French EBLV-1 isolates sampled between 1989 and 2013 and the French BBLV sample against 21 referenced partial nucleoprotein sequences confirmed the low genetic diversity of EBLV-1 despite its extensive geographical range. Statistical analysis performed on the serotine bat data collected from 1989 to 2013 showed seasonal variation of rabies occurrence with a significantly higher proportion of positive samples detected during the autumn compared to the spring and the summer period (34% of positive bats detected in autumn, 15% in summer, 13% in spring and 12% in winter). In this study, we have provided the details of the geographical distribution of EBLV-1a in the south-west of France and the north-south division of EBLV-1b with its subdivisions into three phylogenetic groups: group B1 in the north-west, group B2 in the centre and group B3 in the north-east of France.

However, so far there has been no specific research concerning systemic abnormalities in psoriatic patients. Objective: A retrospective study was conducted focusing on the detailed systemic abnormalities in psoriatic patients. Methods: Psoriatic inpatients data was collected from July 2009 to September 2015. The inclusion criteria were first-time hospitalization and without administration of systemic drug therapy or exposure to phototherapy for psoriasis for at least 1 month. Detailed systemic indexes were mainly evaluated. Results: The abnormality rates of blood routine examination, urine examination, blood biochemical examination and chest X-ray of 43 psoriatic patients were significantly higher than those of 44 non-psoriasis controls, and psoriasis patients significantly had higher absolute values of leukocytes and neutrophils, and significantly lower values of lymphocytes. Compared with psoriasis vulgaris, erythrodermic psoriasis had significantly higher abnormality rates of blood biochemical examination and serum electrolyte analysis. Erythrodermic psoriasis had significantly higher absolute values of blood leukocytes, neutrophils, and lower serum calcium compared with those of psoriasis vulgaris. The neutrophil-to-lymphocyte ratio of controls was significantly lower than that of psoriatic patients, and neutrophil-to-lymphocyte ratio of ­erythrodermic psoriasis was significantly higher in comparison with psoriasis vulgaris. Conclusion: This study

    The efficacy of cabergoline in Cushing's disease (CD) is controversial. The aim of this study was to assess the efficacy and tolerability of cabergoline in a large contemporary cohort of patients with CD. We conducted a retrospective multicenter study from thirteen French and Belgian university hospitals. Sixty-two patients with CD received cabergoline monotherapy or add-on therapy. Symptom score, biological markers of hypercortisolism and adverse effects were recorded. Twenty-one (40%) of 53 patients who received cabergoline monotherapy had normal urinary free cortisol (UFC) values within 12 months (complete responders), and five of these patients developed corticotropic insufficiency. The fall in UFC was associated with significant reductions in midnight cortisol and plasma ACTH, and with clinical improvement. Compared to other patients, complete responders had similar median baseline UFC (2.0 vs 2.5xULN) and plasma prolactin concentrations but received lower doses of cabergoline (1.5 vs 3.5 mg/week, P 12 months), cabergoline was withdrawn in 28% of complete responders because of treatment escape or intolerance. Overall, sustained control of hypercortisolism was obtained in 23% of patients for 32.5 months (19-105). Nine patients on steroidogenesis inhibitors received cabergoline add-on therapy for 19 months (1-240). Hypercortisolism was controlled in 56% of these patients during the first year of treatment with cabergoline at 1.0 mg/week (0.5-3.5). About 20-25% of CD patients are good responders to cabergoline therapy allowing long-term control of hypercortisolism at relatively low dosages and with acceptable tolerability. No single parameter, including the baseline UFC and prolactin levels, predicted the response to cabergoline. © 2017 European Society of Endocrinology.

    To evaluate the forms of treatment employed to heart injuries and the main aspects related to their morbidity and mortality. A retrospective study of 102 patients with cardiac injuries treated in the two emergency rooms in Manaus (Dr. John Lucio Pereira Machado Emergency Hospital and August 28 County Emergency Hospital) from January 1998 to June 2006. Of the 102 patients, 95.1% were men; mean age was 27 years; stab wounds accounted for 81.4% of cases and gunshot wounds for 18.6%; cardiorrhaphy was performed in 98.1% of cases. The heart chambers affected were: Right Ventricle (RV): 43.9% (36.2% isolated and 7.7% associated with other chambers); Left Ventricle (LV): 37.2%; Right Atrium (RA): 8.5%; and Left Atrium (LA): 10.4%; specific mortalities were of 21%, 23%, 22% and 45%, respectively. The mortality injuries to two associated chambers was 37.5%, 20% being for RA + RV, 100% for RV + LV, and zero for RV + LA. The lung accounted for 33.7% of the 89 associated lesions. Mean time of surgery and hospital stay were 121 minutes and 8.2 days, respectively. About 22.5% of patients displayed 41 complications. The mortality rate was 28.4%. Lesions grade IV and V corresponded to 55% and 41% of cases, with specific mortality of 26% and 15%, respectively. All patients with grade injuries VI died. Cardiac stab wounds were associated with lower mortality, cardiac lesions grade IV were associated with higher mortality and a shorter operative time was associated with greater severity and mortality.

    Background: For women with breast cancer, the contralateral breast is at high risk. The bilateral cancers may be synchronous or metachronous. If the bilateral breast cancers have similar ultrasonography (US) appearances, the US findings of the first breast cancer (index cancer) might lead to early detection of the contralateral cancer. The purpose of this study was to identify the US characteristics of bilateral breast cancer and to determine whether bilateral breast cancers have similar US appearances and whether the US findings for one breast cancer might be predictive of the contralateral breast cancer. Methods: We retrospectively reviewed the US manifestations of 58 patients with surgically proven bilateral primary breast cancer and compared the contralateral cancer with the index cancer by evaluation the margin, shape, inside echoes, posterior attenuation, calcification and color flow signals of 58 lesion pairs to investigate whether the bilateral breast cancers have similar US appearances. Results: Bilateral primary breast cancers were more located in upper outer quadrant, frequently spiculation, taller than wide shape, with irregular margin, heterogeneous internal echo and acoustic shadowing, containing microcalcification and abundant color flow signals. The most common US appearances were taller than wide shape (75.0%, 87/116), irregular margins (79.3%, 92/116) and heterogeneous internal echo (86.2%, 100/116). Of the total 58 lesion pairs, 18 (31.0%) pairs had similar US characteristics, whereas 40 (69.0%) pairs had different US characteristics. Conclusions: US signs of the index cancer do not indicate the most likely appearance of the second cancer in the contralateral breast. Evaluation of the contralateral cancer should be performed without regard for the US findings for the index cancer.

    Background 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. Material and Methods 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. Results 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. Conclusions 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.

    Atypical squamous cells of undetermined significance (ASCUS) are a cervical cytologic finding category suggestive but not definitive of squamous intraepithelial lesions. ASCUS remains an incompletely described entity and accounts for even 5%-10% of reported Papanicolaou (Pap) smears. The management of women with such cytologic findings remains controversial. The aim of this study was to evaluate the cytology laboratory findings with regards to ASCUS diagnosis, using cervical Pap smears, and colposcopic biopsies, as well as their management. This is a retrospective study of patients with ASCUS Pap smears taken during the period January 2010 - December 2010 in the Second Department of Obstetrics and Gynecology, Aretaieion Hospital. During the study period, 657 Pap smears were examined at the Aretaieion Hospital; moreover, seven patients, whose Pap smears were cytologically diagnosed with ASCUS, were referred from other clinics, providing a total of 42 cases with a descriptive diagnosis of ASCUS for review. Of the 42 cases, eight were not studied because they were either lost in follow-up or they did not have available data. The remaining 34/42 patients were evaluated by colposcopic examination and directed biopsies where necessary. The ratio of ASCUS to low-grade squamous intraepithelial lesion (LGSIL), high-grade squamous cell intraepithelial lesion (HGSIL) or squamous cell carcinoma (SCC) was 5/34, 1/34, and 0/34, respectively. In the 34 ASCUS cases evaluated by colposcopy, the age distribution varied from 22 to 54 years. Eight of 34 cases did not have a child, 7/34 were primigravida, 18/34 were secondi-gravida, and 1/34 had four children. Four out of 34 cases were postmenopausal, 3/34 referred no history of abnormal bleeding, 21/34 were smokers, 6/34 used oral contraceptives, 2/34 used intrauterine devices, 1/34 took replacement of hormones, 4/34 had prior abnormal Pap smears human papillomavirus (HPV), or 1/34 had previous cancer (breast cancer).

    Bevacizumab (BEV), a humanized anti-vascular endothelial growth factor (VEGF) monoclonal antibody, enhances the antitumor effectiveness of paclitaxel (PTX)-based chemotherapy in many metastatic cancers. A recent study in mice showed that VEGF receptor inhibitors can interfere with the neuroprotective effects of endogenous VEGF, potentially triggering the exacerbation of PTX-induced neuropathy. In clinical trials, exacerbation of neuropathy in patients who received PTX combined with BEV (PTX+BEV) has generally been explained by increased exposure to PTX owing to the extended duration of chemotherapy. We investigated whether the concurrent use of BEV is associated with the exacerbation of PTX-induced neuropathy. Female patients with breast cancer who had received weekly PTX or PTX+BEV from September 2011 through May 2016 were studied retrospectively. PTX-induced neuropathy was evaluated at the same time points (at the 6th and 12th courses of chemotherapy) in both cohorts. A multivariate Cox proportional-hazards model was used to assess the independent effect of BEV on the time to the onset of neuropathy. A total of 107 patients (median age, 55 years; range, 32-83) were studied. Sixty-one patients received PTX as adjuvant chemotherapy, 23 received PTX for metastatic disease, and 23 received PTX+BEV for metastatic disease. Peripheral sensory neuropathy was worse in patients who received PTX+BEV than in those who received PTX alone: at the 6th course, Grade 0/1/2/3 = 4/13/4/0 vs. 25/42/6/0 (P = 0.095); at the 12th course, 2/3/11/3 vs. 7/30/23/2 (P = 0.016). At the 12th course, the incidence of Grade 2 or higher neuropathy was significantly higher in patients treated with PTX+BEV than in those treated with PTX alone (74% vs. 40%; P = 0.017). In multivariate analysis, BEV was significantly associated with an increased risk of neuropathy (HR 2.32, 95% CI 1.21-4.44, P = 0.012). The concurrent use of BEV could worsen PTX-induced neuropathy in patients with breast cancer.

    Information regarding the clinical features of patients with anorexia nervosa in Singapore is rare and there have not been any large studies published to date. The aims of this paper were to study the clinical characteristics and features of patients with anorexia nervosa in Singapore, and to compare the clinical features of the early versus the classical later-onset cases. 126 cases presenting to the Child Guidance Clinic and the Eating Disorder Clinic at the Institute of Mental Health between 1994 and 2002 were identified and studied retrospectively. All presented with anorexia nervosa or had a past history of it. Subjects were further classified into early-onset (younger than 14 years) or classical later-onset (14 years and older), and a comparison was done between the two groups. The large majority were female students with a mean presenting age of 17.6 years. 65.1 percent were of the restricting subtype. 84.1 percent were Chinese, 7.9 percent were Indians and 4.8 percent were Malays. Mean presenting body mass index (BMI) was 15.56. Depression was the most common co-morbid condition affecting 25.4 percent of the sample. The number of new cases increased significantly from six in 1994 to 24 in 2002 (p-value equals 0.002). Commonest precipitating factors were comments from others, school and work stress. 11.1 percent were previously members of trim and fit club in school. 42.7 percent of late-onset cases compared to 16.2 percent of the early-onset were of the binge-purge type (p-value equals to 0.005) and had a higher presenting BMI (15.91 +/- 2.90 versus 14.74 +/- 2.14, p-value equals 0.003). The clinical characteristics of patients with anorexia nervosa in Singapore are similar to that reported in western literature. The Malay population appears to be under-represented. There was a significant increase in numbers presenting over the last two years. The early-onset cases tend to be of the restrictive-type and had a lower presenting BMI than the later-onset group.

    Isatin is a small, versatile and widely applicable pharmacological molecule. These characteristics make isatin and its derivatives attractive to many research groups as resources for chemical and pharmacological studies. Although it has a relatively simple structure, isatin is a useful chemical scaffold for a variety of chemical transformations. This article discusses several studies performed by Brazilian groups, including investigations of its structural changes, biological assay designs and new methods for the synthesis of isatin.

    With successful antiretroviral therapy, non-communicable diseases, including malignancies, are increasingly contributing to morbidity and mortality among HIV-infected persons. The epidemiology of AIDS-defining cancers (ADCs) and non-AIDS-defining cancers (NADCs) in HIV-infected populations in Brazil has not been well described. It is not known if cancer trends in HIV-infected populations in Brazil are similar to those of other countries where antiretroviral therapy is also widely available. We performed a retrospective analysis of clinical cohorts at Instituto Nacional de Infectologia Evandro Chagas (INI) in Rio de Janeiro and Vanderbilt Comprehensive Care Clinic (VCCC) in Nashville from 1998 to 2010. We used Poisson regression and standardized incidence ratios (SIRs) to examine incidence trends. Clinical and demographic predictors of ADCs and NADCs were examined using Cox proportional hazards models. This study included 2,925 patients at INI and 3,927 patients at VCCC. There were 57 ADCs at INI (65% Kaposi sarcoma), 47 at VCCC (40% Kaposi sarcoma), 45 NADCs at INI, and 82 at VCCC. From 1998 to 2004, incidence of ADCs remained statistically unchanged at both sites. From 2005 to 2010, ADC incidence decreased in both cohorts (INI incidence rate ratio per year = 0.74, p < 0.01; VCCC = 0.75, p < 0.01). Overall Kaposi sarcoma incidence was greater at INI than VCCC (3.0 vs. 1.2 cases per 1,000 person-years, p < 0.01). Incidence of NADCs remained constant throughout the study period (overall INI incidence 3.6 per 1,000 person-years and VCCC incidence 5.3 per 1,000 person-years). Compared to general populations, overall risk of NADCs was increased at both sites (INI SIR = 1.4 [95% CI 1.1-1.9] and VCCC SIR = 1.3 [1.0-1.7]). After non-melanoma skin cancers, the most frequent NADCs were anal cancer at INI (n = 7) and lung cancer at VCCC (n = 11). In multivariate models, risk of ADC was associated with male sex and immunosuppression. Risk of

    Para-infectious seizures are afebrile seizures that are associated with mild infections, and occur in children with no pre-existing neurological illness. They are still little known in our environment. A multicentre retrospective study was conducted that included patients with normal psychomotor development and had presented with one or more seizures in the context of a mild afebrile infection. A total of 38 patients (47% male, 53% female) were included in the study over a period of three years (2012-2015). The mean age was 2.1 years. A previous history of febrile seizures was found in 7.9% of them. Mean number of seizures per patient was 2.2, with 57.9% of them being tonic-clonic seizures. The mean duration of seizures was 3.2minutes. An EEG was performed during admission in 73.7% of cases. Lumbar punctures were performed in 34.2% of cases. All were normal. Neuroimaging tests were carried out in 36.9% of cases. Brain MRI was the imaging test performed in most cases (21.1%), with no any pathological findings. The most frequent infection found was acute gastroenteritis (68%), followed by upper respiratory tract infection (32%). Almost two-thirds (63.2%) of patients did not require anticonvulsant medication. Rectal diazepam was the most frequently used drug in emergencies. Intravenous medication was required by 28.9% of patients due to repeated seizures. The most frequently used drug in the non-emergency setting was valproic acid. Anticonvulsant treatment was continued after discharge in 16% of patients. Para-infectious seizures was the diagnosis in 76.3% of cases when discharged. Knowledge of para-infectious seizures, their clinical diagnosis and benign course is crucial, as this would avoid further testing and unnecessary treatments.

    Full Text Available Background and objective Bronchopulmonary carcinoid (BPC account for less than 2% of all primary lung malignant tumors, but few related studies were reported. The aim of this study is to analyze this rare disease’s clinicopathological characteristics. Methods The clinical data of 28 patients with BPC in Cancer Center of Sun Yat-sen University, from January 1994 to June 2009, were enrolled into retrospective analysis. First, the corresponding paraffin blocks reexamined, slice up and stained, multiple pathologists re-consulted, and its subsets (typical carcinoid, TC; atypical carcinoid, AC defined. Second, the clinical characteristics and immunohistochemical markers and its relationship with prognosis were analyzed. Results First, the 5-year survival for overall and TC, AC was 56% and 70%, 41% respectively in 28 cases. The markers CD99, Bcl-2 and Ki-67 expression correlated significantly with the BPC subsets (P=0.017, P=0.043, and P=0.033 respectively. Further univariate analysis revealed that advanced TNM staging (P=0.037, lymph node metastasis (P=0.001 and Ki-67 nucleolus’s positive expression (P=0.009 are poor prognostic factors. Second, the overall, TC, AC 5-year survival rate was 73%, 83%, 57% respectively in 20 cases underwent the radically surgical resection. Further univariate analysis revealed that AC subset (P=0.013, lymph node metastasis (P=0.004 and Ki-67 nucleolus’s positive expression (P=0.006, advanced TNM staging (P=0.047 are poor prognostic factors in this 20 cases. Third, as univariate analysis, local recurrence and metastasis (n=4 correlate significantly with Ki-67 nucleolus’s and Bcl-2 positive expression (P=0.027, 0.045, respectively. Conclusion The prognosis of BPC was better than other types of primary lung cancer. Ki-67, bcl-2 high expression and advanced TNM staging are the poor recurrence and prognostic factors of BPC. The radical surgery remains the treatment of choice for resectable candidates in BPC as NSCLC.

    Full Text Available OBJECTIVE Determine the coverage rate of syphilis testing during prenatal care and the prevalence of syphilis in pregnant women in Brazil. METHODS This is a national hospital-based cohort study conducted in Brazil with 23,894 postpartum women between 2011 and 2012. Data were obtained using interviews with postpartum women, hospital records, and prenatal care cards. All postpartum women with a reactive serological test result recorded in the prenatal care card or syphilis diagnosis during hospitalization for childbirth were considered cases of syphilis in pregnancy. The Chi-square test was used for determining the disease prevalence and testing coverage rate by region of residence, self-reported skin color, maternal age, and type of prenatal and child delivery care units. RESULTS Prenatal care covered 98.7% postpartum women. Syphilis testing coverage rate was 89.1% (one test and 41.2% (two tests, and syphilis prevalence in pregnancy was 1.02% (95%CI 0.84;1.25. A lower prenatal coverage rate was observed among women in the North region, indigenous women, those with less education, and those who received prenatal care in public health care units. A lower testing coverage rate was observed among residents in the North, Northeast, and Midwest regions, among younger and non-white skin-color women, among those with lower education, and those who received prenatal care in public health care units. An increased prevalence of syphilis was observed among women with < 8 years of education (1.74%, who self-reported as black (1.8% or mixed (1.2%, those who did not receive prenatal care (2.5%, and those attending public (1.37% or mixed (0.93% health care units. CONCLUSIONS The estimated prevalence of syphilis in pregnancy was similar to that reported in the last sentinel surveillance study conducted in 2006. There was an improvement in prenatal care and testing coverage rate, and the goals suggested by the World Health Organization were achieved in two regions

    Full Text Available ABSTRACT BACKGROUND: Electrocardiograms (ECGs are an essential examination for identification and management of cardiovascular emergencies.The aim of this study was to report on the frequency and recognition of cardiovascular emergencies in primary care units. DESIGN AND SETTING: Observational retrospective study assessing consecutive patients whose digital ECGs were sent for analysis to the team of the Telehealth Network of Minas Gerais. METHODS: Data from patients diagnosed with cardiological emergencies in the primary care setting of 750 municipalities in Minas Gerais, Brazil, between March and September 2015, were collected via telephone contact with the healthcare practitioner who performed the ECG. After collection, the data were subjected to statistical analysis. RESULTS: Over the study period, 304 patients with cardiovascular emergencies were diagnosed within primary care. Only 73.4% of these were recognized by the local physicians. Overall, the most frequent ECG abnormalities were acute ischemic patterns (44.7% and the frequency of such patterns was higher among the ECGs assigned as emergency priority (P = 0.03. It was possible to obtain complete information on 231 patients (75.9%. Among these, the mean age was 65 ± 14.4 years, 57.1% were men and the most prevalent comorbidity was hypertension (68.4%. In total, 77.9% were referred to a unit caring for cases of higher complexity and 11.7% of the patients died. CONCLUSION: In this study, cardiovascular emergencies were misdiagnosed in primary care settings, acute myocardial ischemia was the most frequent emergency and the mortality rate was high.

    The use of abdominal radiographs contributes to increased healthcare costs, radiation exposure, and potentially to misdiagnoses. We evaluated the association between abdominal radiograph performance and emergency department (ED) revisits with important alternate diagnosis among children with constipation. Retrospective cohort study of children aged constipation at one of 23 EDs from 2004 to 2015. The primary exposure was abdominal radiograph performance. The primary outcome was a 3-day ED revisit with a clinically important alternate diagnosis. RAND/University of California, Los Angeles methodology was used to define whether the revisit was related to the index visit and due to a clinically important condition other than constipation. Regression analysis was performed to identify exposures independently related to the primary outcome. A total of 65.7% (185 439/282 225) of children with constipation had an index ED visit abdominal radiograph performed. Three-day revisits occurred in 3.7% (10 566/282 225) of children, and 0.28% (784/282 225) returned with a clinically important alternate related diagnosis. Appendicitis was the most common such revisit, accounting for 34.1% of all 3-day clinically important related revisits. Children who had an abdominal radiograph performed were more likely to have a 3-day revisit with a clinically important alternate related diagnosis (0.33% vs 0.17%; difference 0.17%; 95% CI 0.13-0.20). Following adjustment for covariates, abdominal radiograph performance was associated with a 3-day revisit with a clinically important alternate diagnosis (aOR: 1.39; 95% CI 1.15-1.67). Additional characteristics associated with the primary outcome included narcotic (aOR: 2.63) and antiemetic (aOR: 2.35) administration and underlying comorbidities (aOR: 2.52). Among children diagnosed with constipation, abdominal radiograph performance is associated with an increased risk of a revisit with a clinically important alternate related diagnosis

    To summarize the presenting complaints and clinical signs associated with traumatic penetrating injuries to the canine oropharynx. To determine how the site of injury, causative agent, and duration of disease affect the presentation and clinical outcome of treatment. Retrospective study. 50 client-owned dogs. The medical records of 50 dogs with oropharyngeal penetrating injuries referred to Glasgow University Veterinary Hospital (GUVH) between 1979-1999 were reviewed. Data regarding signalment, owners' presenting complaint, history, physical examination, radiographic and endoscopic findings, surgical findings, and outcome were recorded and compared with the GUVH population. Estimates of individual breed-specific odds ratios were calculated. Outcome was evaluated by reexamination 6 weeks after surgery with recurrence of disease recorded as failure. Oropharyngeal injuries occurred most often in medium to large breed dogs. The majority of dogs presented with chronic disease (82%). The common findings on clinical examination were discharging sinus (72%) and swelling (70%). Acute cases typically presented with dysphagia and oral pain. The original site of injury was evident in only 34% of dogs, with the sublingual area the most frequently traumatized. The apparent cause of injury to the oropharynx was most commonly a piece of wood (72%). Other causes were metallic foreign bodies (3 dogs) and bones (2 dogs). In the remaining 9 dogs, the cause was not determined. The clinical signs resolved in all dogs that presented acutely compared with only 62% in dogs with chronic signs. Medium to large breed dogs appear to be prone to oropharyngeal injuries caused mainly by wooden foreign bodies. This may be attributable to stick chewing or retrieving behavior in these animals. History of trauma, stick retrieval, submandibular/cervical swelling, and discharging sinus are commonly encountered in the presentation of this condition. The sublingual area was the most frequent portal of

  8. Impact of regulatory assessment on clinical studies in Brazil

    Luis Augusto Tavares Russo

    Full Text Available SUMMARY Introduction: Despite the recent expansion of clinical studies allocated to Brazil, the delay of local regulatory deadlines directly impacts their completion. Objective: This article examines the allocation process of clinical studies to Brazil in comparison with other countries, as well as the financial impact of studies not completed due to interruption caused by the delay in the regulatory process. Method: The allocation processes of studies were compared in nine countries with similar stages of economic development and countries in Latin America using the websites http://data.worldbank.org/data-catalog/GDP-rankings-table and http://worldpopulationreview.com and clinicaltrials.gov, comprising 185 countries. The 46 studies sponsored by the pharmaceutical industry underwent an analysis of the regulatory review process. Results: 46 studies sponsored by the industry and submitted in the country between June 2007 and June 2013 were analyzed; 18 (39% were discontinued due to the delay in obtaining the necessary approvals. For the approved studies, patient recruitment began an average of 11 months after the other countries. It is estimated that 530 Brazilians patients did not have the opportunity to participate in these studies. Financial losses were to the order of 14.6 million dollars for the country, including patient, medication and supplies costs, and expenses. Conclusion: Brazil has enormous potential for the realization of clinical studies. Researchers, associations of disabled people and patients with chronic diseases, sponsors and the authorities must work together to develop an approval process that is efficient, predictable and, most of all, transparent. The current regulatory environment must and can be improved and optimized in order to result in tangible benefits for patients, society and the country’s scientific development.

    Our objectives were to examine demographic and ethnic factors associated with amyotrophic lateral sclerosis in Brazil. The method used was a retrospective study of death certificates performed in June 2015, identifying the incidence of amyotrophic lateral sclerosis over 10 years, from January 2004 to December 2013, related to gender, age and race. Results revealed 8942 death certificates with 8152 as the underlying cause and 790 as a secondary cause. The average age was 62.7 ± 13.2 years, with a predominance of males (1·3:1). The adjusted mortality rate over 20 years was 0.61 to 0.89/100,000 person-years, and over 45 years was 1.77 to 2.3/100,000 person-years. There was a predominance of amyotrophic lateral sclerosis in Caucasians compared to the general population above 20 years (2010 Census), with an odds ratio (OR) of 2.92 (95% CI 2.78-3.07). The OR in blacks was 0.04 (95% CI: 0.03-0.04), in mestizos was 0.05 (0.04-0.07), and in Indians was 0.02 (0.01-0.04). The mean age was lower than in European populations (48.5 ± 12.3 years) (p amyotrophic lateral sclerosis in Brazil is close to other Latin American populations, with a lower age at death and clear predominance in Caucasians.

    To date, the clinical features of the various subtypes of conjunctival lymphoma (CL) have not been previously evaluated in a large cohort. To characterize subtype-specific clinical features of CL and their effect on patient outcome. A retrospective multicenter study was performed. Patient data were collected from January 1, 1980, through December 31, 2010. The dates of the analysis were May 15, 2015, to August 20, 2015. The median follow-up period was 43 months. Seven eye cancer centers were involved in the study. In total, 268 patients with CL were identified, 5 of whom were excluded because of missing clinical data. Overall survival, disease-specific survival, and progression-free survival were the primary end points. Two hundred sixty-three patients with CL were included in the study. Their mean age was 61.3 years, and 55.1% (145 of 263) were female. All lymphomas were of B-cell type. The most frequent subtype was extranodal marginal zone lymphoma (EMZL) (68.4% [180 of 263]), followed by follicular lymphoma (FL) (16.3% [43 of 263]), mantle cell lymphoma (MCL) (6.8% [18 of 263]), and diffuse large B-cell lymphoma (DLBCL) (4.6% [12 of 263). Conjunctival lymphoma commonly manifested in elderly individuals (age range, 60-70 years old), with EMZL having a female predilection (57.8% [104 of 180]) and MCL having a marked male predominance (77.8% [14 of 18]). Unlike EMZL and FL, DLBCL and MCL were frequently secondary diseases (41.7% [5 of 12] and 88.9% [16 of 18], respectively), with MCL showing a frequent occurrence of stage IVE lymphoma (61.1% [11 of 18]) and bilateral manifestation (77.8% [14 of 18]). Localized disease (stage IE or IIE) was commonly treated with external beam radiation therapy (EBRT) with or without chemotherapy, while widespread lymphoma (stage IIIE or IVE) and MCL of any stage were managed with chemotherapy with or without EBRT. Diffuse large B-cell lymphoma and MCL had a poor prognosis, with 5-year disease-specific survival of 55.0% and 9

    Full Text Available Aim. The aim of our study was to determine the prevalence of psoriatic arthritis in the patients with psoriasis and to analyze retrospectively the results of a 34-year multidisciplinary management of the patients with psoriatic arthritis. Methods. The study included 162 out of 183 treated patients with psoriatic arthritis, aged 48 ± 15 years. All the patients satisfied the current diagnostic criteria for psoriasis and psoriatic arthritis according to the American College of Rheumatology. Results. Psoriatic arthritis developed in 183 (9.3% out of 1976 patients with psoriasis. Time interval for establishing the diagnosis was 4 years. A positive family history of the disease had 15.0% of the studied patients. Its onset was most often at 42 years of age in 70.4% of the cases, and 2 months to 59 years after the appearance of psoriasis. Psoriatic arthritis without psoriasis appeared in 1.8% of the patients. A severe form of arthritis had 64.2% of the patients, mainly the patients with scalp psoriasis (χ2=3.2; p<0.05. Nail changes had 35% of the patients. Distal interphalangeal joints were involved in 63.6%, axial skeleton in 36.4%, oligoarthritis in 45.0%, polyarthritis in 55.0%, and mutilating form in 6.8% of the patients. Elevated Erythrocyte Sedimentation Rate was reveald in 61.7% of the patients. Immunoglobulin M (IgM rheumatoid factor was altered in 4.3% of the patients. The human leukocyte antigen (HLA typing in the 28 patients were: A2 32.0%, A3 18.0%, Al and A9 14.0%, A28 and A29 3.5%, B8 and B16 14.0%, B5 and B12 11.0%, B13,B15, B18, B27 and B35 7.0%. Radiologic changes were most often in hand and foot joints, less frequently in the knees and quite infrequently in hips and shoulders joints. Sacroiliitis was found in 46.4% of the patients. Psoriasis was treated with topical corticosteroids and salicylic ointments in all the patients, ultraviolet (PUVA therapy in 5.6% and retinoids in 4.3% of them. Artrithis was treated with nonsteroidal anti

    The shortage of registered nurses is an issue globally, but particularly in rural and remote areas. Previous research in medicine suggests that recruiting students from rural backgrounds is an effective strategy to enhance the supply of rural healthcare providers. This strategy has not been widely adopted or evaluated in nursing. The purpose of this study was to compare rural and urban nursing students in relation to application, admission, and retention/graduation trends at a metropolitan state university in the Pacific Northwest area of the USA. A retrospective longitudinal descriptive design was used, analyzing existing data from 2005 to 2010. The sample included 1283 applicants, accepted students, and graduates. Rural-urban classification was made using rural urban commuting area (RUCA) codes based on high school zip codes, identifying 356 (28%) rural and 927 (72%) urban individuals. The data were analyzed quantitatively, assessing demographic characteristics along with application, admission and retention/graduation rates. The analysis indicated no significant differences between the rural and urban samples in relation to age, gender, parents' level of education, income, or retention rates. The acceptance rate for rural students (66.3%) was significantly lower than for urban students (73.1%) (p=0.015). When rural subgroups (isolated, small rural and large rural) were examined, the isolated group (n=61) had the highest acceptance rate of any rural or urban group (75%). This group was the least ethnically diverse (95% Caucasian), was the least likely to be first-generation college (22%), had the highest percentage of females (85%) and had the highest entering grade point average (3.65 on a four-point scale). In contrast, the subgroup including individuals from large rural communities (n=182) had the lowest acceptance rate (64%), the lowest retention rate 85%, the lowest entering grade point average (3.42), and the highest percentage of first-generation college

    Childhood melanoma can be misdiagnosed because of its rarity and atypical presentation. We sought to correlate the clinical appearance of pediatric melanomas with Breslow depth and clinical behavior, and to identify diagnostic errors made by dermatologists and nondermatologist physicians. This was a retrospective review of Mayo Clinic records of children and young adults 21 years of age or younger with a diagnosis of primary cutaneous melanoma between January 2000 and January 2015. Pediatric melanomas that mimicked benign skin lesions were more often deeper (>1 mm; odds ratio 5.48; P = .002) and had a higher T stage (odds ratio [T2, T3, or T4] 6.28; P = .001) than melanomas with a clinically malignant appearance. Of pediatric melanomas, 66% originally diagnosed as benign melanocytic lesions exhibited changes in size, shape, and color. Sample size and retrospective design are limitations. Benign-appearing pediatric skin lesions with a history of evolution, bleeding, or ulceration should raise suspicion for melanoma. Melanomas demonstrating these features are associated with a higher Breslow depth and T stage. Although biopsy of all lesions that exhibit change in children is not practical, safe, or desired, close monitoring is recommended. Copyright © 2016 American Academy of Dermatology, Inc.

    Full Text Available The aim of this study is to present a comparison between the main actions promoted to encourage innovation by France, as well as the current stage of research and development initiatives (R&D, in relation to Brazil. Is a qualitative study that the procedures for its development ranks as literature and documents. The data collection technique was documentary and had as a data source primary and secondary documents, coming from public archives and statistical sources. For the survey of brazilian data for the development of this study, it was used as informational basis the fifth edition of the Innovation Research (PINTEC 2011. The data from France raised through the use of OECD year Report 2014 " Reviews of Innovation Policy France in 2014."  For the presentation of the study results comparative charts and tables were used. As the present study results can be highlighted, among others: France is a country with a long scientific tradition and technique, and plays a significant role in the world in this area. On the other hand, Brazil has one of the lowest proportions of R&D and export of high technology to GDP. The completion of this study brought an important diagnosis: there is a wide and interesting research topic that is still little explored by Brazilian researchers.

    In the developed world, kidney transplantation (KT) in patients with human immunodeficiency virus (HIV) infection is well established. Developing countries concentrate 90% of the people living with HIV, but their experience is underreported. Regional differences may affect outcomes. We compared the 3-year outcomes of patients with HIV infection receiving a KT in two different countries, in terms of incomes and development. This was an observational, retrospective, double-center study, including all HIV-infected patients >18 years old undergoing KT. Between 2005 and 2015, 54 KTs were performed (39 in a Brazilian center, and 15 in a Spanish center). Brazilians had less hepatitis C virus co-infection (5% vs 27%, P=.024). Median cold ischemia time was higher in Brazil (25 vs 18 hours, P=.001). Biopsy-proven acute rejection (AR) was higher in Brazil (33% vs 13%, P=.187), as were the number of AR episodes (22 vs 4, P=.063). Patient survival at 3 years was 91.3% in Brazil and 100% in Spain; P=.663. All three cases of death in Brazil were a result of bacterial infections within the first year post transplant. At 3 years, survival free from immunosuppressive changes was lower in Brazil (56% vs 90.9%, P=.036). Raltegravir-based treatment to avoid interaction with calcineurin inhibitor was more prevalent in Spain (80% vs 3%; P<.001). HIV infection remained under control in all patients, with undetectable viral load and no opportunistic infections. Important regional differences exist in the demographics and management of immunosuppression and antiretroviral therapy. These details may influence AR and infectious complications. Non-AIDS infections leading to early mortality in Brazil deserve special attention. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    To investigate the epidemiology, risk factors and clinical course of acute hepatitis E virus (HEV) infection in Israel, an industrialized country. A retrospective analysis of acute HEV cases diagnosed in Israel from 1993 to 2013. Acute HEV was defined by ALT/AST elevation and a positive HEV PCR test or positive anti-HEV-IgM serology. HEV RNA was tested by quantitative reverse transcription PCR. Antibodies to HEV were tested retrospectively using an ELISA assay. HEV-RNA was sequenced using RT-PCR of ORF1 and ORF2 regions to diagnose genotype of the virus. Epidemiologic and clinical data were collected by reviewing the clinical files and through a telephone interview according to a structured questionnaire. Acute HEV was diagnosed in 68 patients. Among the 59 patients who gave an informed consent and were interviewed, 41% of infections were autochthonous (acquired in Israel), 44% travel-related and 15% imported by foreign workers. Autochthonous patients were mainly females (62.5%), more than half of them pregnant, 26% recalled consuming food or water in areas with poor sanitation, 44% ate non-kosher meat. Fulminant hepatitis developed in 3 patients (5%), all of them were females, two of them with post-partum infection, all acquired the disease in Israel (autochthonous). Israeli travelers with imported infection were predominantly males (73%), acquired the disease in the Indian subcontinent (81%), with 100% reporting having consumed fresh vegetables and drinks with ice cubes abroad. Six patients' sera were tested for genotype and revealed HEV genotype 1 (all cases acquired in the Indian subcontinent). This is the first report which highlights the existence of hepatitis E as an autochthonous infection in Israel. Imported HEV originates mostly from the Indian subcontinent.

    This paper describes the main methodological aspects of a cohort study, with emphasis on its recent phases, which may be relevant to investigators planning to carry out similar studies. In 1993, a population based study was launched in Pelotas, Southern Brazil. All 5,249 newborns delivered in the city’s hospitals were enrolled, and sub-samples were visited at the ages of one, three and six months and of one and four years. In 2004-5 it was possible to trace 87.5% of the cohort at the age of 10-12 years. Sub-studies are addressing issues related to oral health, psychological development and mental health, body composition, and ethnography. Birth cohort studies are essential for investigating the early determinants of adult disease and nutritional status, yet few such studies are available from low and middle-income countries where these determinants may differ from those documented in more developed settings.

    Full Text Available Background and Aims: Twin pregnancy with monochorionic placenta may be associated with arteriovenous vascular anastomosis of the placental vessels resulting in twin-to-twin transfusion syndrome (TTTS and twin reversed arterial perfusion syndrome (TRAP. Foetoscopic LASER ablation (FLA is the treatment of choice in reducing foetal mortality related to this. Methods: A retrospective review of medical records of 41 FLA procedures for TTTS and TRAP were analysed for anaesthetic management. Thirty-four patients received subarachnoid block, three combined spinal-epidural block, three general anaesthesia and one local anaesthesia with sedation. Nitroglycerine 5 mg patch was used for tocolysis 1 h before the procedure and continued for 24-48 h postoperatively. Results: Bupivacaine was used in 34 patients, and ropivacaine in three patients. Mean dose of bupivacaine 0.5% was 2.43 ± 0.32 ml and ropivacaine 0.75% was 2.85 ± 0.19 ml. The mean duration of surgery was 117.07 ± 28 min. Mild hypotension occurred in all patients under spinal anaesthesia and was treated with vasopressors. The foetal outcome among all 41 patients were 13 delivered live twins, 15 had a single live baby with intrauterine death of other twin baby. In 12 patients, both babies were intrauterine death. One patient was lost for follow-up. Conclusion: Foetoscopic procedures can be done under central neuraxial block, however occasionally general anaesthesia may be required.

    To investigate the epidemiological characteristics, clinical manifestations, diagnosis, and treatment of Brucella orchitis, so as to provide reliable evidence for the prevention and treatment of the disease. We conducted retrospective statistical analyses on the medical records of 48 outpatients and 21 inpatients with Brucella orchitis. Brucella orchitis was diagnosed in 6.67% of the male patients with brucellosis (69/1 034). The disease exhibited typical epidemiological features, with a higher incidence rate among those in frequent contact with sheep and elderly people, in the period from April to July, and in the areas with sheep husbandry. All the Brucella orchitis patients had such local symptoms as testicular pain and swelling, more frequently involving both testes, and other most common symptoms included fever, chills, sweating, and painful joints. Based on IIEF-5, 45 of the patients suffered from severe erectile dysfunction, with their reproductive function temporarily affected in the course of the disease. Misdiagnosis easily occurred in the early stage of the disease. Therapeutic options mainly included doxycycline hydrochloride and rifampicin, administered orally or intravenously, which could effect a cure, though relapse might occur in some cases. Bru- cella orchitis has distinct epidemiological characteristics, with clinical manifestations of testicular pain and swelling. Though a transient disease, it affects the reproductive function of the patient before cured. It can be treated by combined oral and intravenous medication, with painkillers or ice bags for testicular pain and swelling.

    Retrospectively, we assessed the likelihood that peri-implantitis was associated with a history of systemic disease, periodontitis, and smoking habits. Data on probing pocket depth (PPD), bleeding on probing (BOP), and radiographic bone levels were obtained from individuals with dental implants. Peri-implantitis was defined as described by Sanz & Chapple 2012. Control individuals had healthy conditions or peri-implant mucositis. Information on past history of periodontitis, systemic diseases, and on smoking habits was obtained. One hundred and seventy-two individuals had peri-implantitis (mean age: 68.2 years, SD ± 8.7), and 98 individuals (mean age: 44.7 years, SD ± 15.9) had implant health/peri-implant mucositis. The mean difference in bone level at implants between groups was 3.5 mm (SE mean ± 0.4, 95% CI: 2.8, 4.3, P implantitis and in 3.0% of individuals in the implant health/peri-implant mucositis group. When adjusting for age, smoking, and gender, odds ratio (OR) of having peri-implantitis and a history of cardiovascular disease was 8.7 (95% CI: 1.9, 40.3 P implantitis, a high likelihood of comorbidity was expressed by a history of periodontitis and a history of cardiovascular disease. © 2013 John Wiley & Sons A/S.

    Autologous rotational keratoplasty is a therapeutic option in patients with central corneal scars. Its advantage compared to allogeneic procedures is the absence of immunologic destruction. In this retrospective analysis, long-term results are presented. Since 1988, autologous rotational keratoplasty was performed in 19 patients. The trephine size varied between 7.0 mm and 9.0 mm. Mean follow-up was 7.1+/-4.6 years. In 16 of the patients, the graft center remained clear during the entire follow-up period. Visual acuity improved from 0.25+/-0.16 preoperatively to 0.34+/-0.27 postoperatively with spectacles and to 0.43+/-0.3 with contact lenses. The mean postoperative astigmatism was 6.41+/-3.87 dpt with irregular components in six patients. Only a few postoperative graft complications were observed. Especially in patients with a markedly elevated risk for immune reactions (e.g., small infants), autologous rotational keratoplasty is a safe alternative to allogenic procedures.

    We aimed to evaluate a wide spectrum of clinical features of adult patients with spondyloarthritis (SpA) whose initial manifestation was fever, using the Assessment of SpondyloArthritis international Society (ASAS) classification criteria. We retrospectively collected the electronic medical records of hospitalized SpA patients who initially presented to the Severance Hospital (Seoul, Korea) with fever from January 2010 to May 2016. As a control group, we also recruited one-hundred consecutive patients who were diagnosed with SpA in our outpatient clinic. Clinical features and laboratory findings were compared in two patient groups. There were 26 patients who had fever as initial presentation of SpA (reactive arthritis 50%, undifferentiated SpA 26.9%, ankylosing spondylitis 15.4%, enteropathic arthritis 3.8%, psoriatic arthritis 3.8%). Peripheral SpA was more common in febrile SpA patients than in control SpA patients (65.4% vs 24.0%, pmanifestation. Febrile SpA patients demonstrated higher systemic inflammation and a lower chance to visit rheumatology in early stage. When evaluating febrile patients with any clinical features of SpA, clinicians are advised to consider performing SpA-focused evaluation including HLA-B27 or a simple sacroiliac joint radiograph.

    Full Text Available Abstract Background To analyze the imaging features of hibernomas on computed tomography (CT and magnetic resonance (MRI. Methods Twelve hibernomas were retrospectively assessed with CT and MR imaging and compared to the histology of the specimen Results Nine females and three males with a mean age of 30 years were included. Ten tumors occurred in the thigh and two affected the subcutis of the periscapular and buttock regions. On eight CT scans, seven (87,5% lesions were homogeneous and mildly to moderately hyperdense compared to subcutaneous fat while one lesion was heterogeneous with mixed hypo and hyperattenuating areas. On six T1W images, five (83,3% lesions appeared homogeneous and hypointense relative to subcutaneous fat and one was heterogeneous. Incomplete fat suppression was depicted in all cases. All lesions displayed marked enhancement. Large intratumoral vessels were depicted in three of the 12 (25% cases. Septations were depicted on four of the eight unenhanced CT and on all six MRI examinations. Conclusions Hibernoma usually appears hypodense and hypointense relative to subcutaneous fat on pre-contrast CT and MR T1W with variable enhancement patterns and incomplete fat suppression on STIR or fat-saturated sequences. These characteristics relate directly to the presence of brown fat. However, atypical findings such as heterogeneous patterns of mixed fatty and non fatty components on unenhanced CT and MR T1W can be also encountered. Absence of large intratumoral vessels should not exclude hibernomas from the differential diagnosis of regional lipomatous tumors.

    Full Text Available Nicholas Hope,1 Caroline P Smith,1 Jim R Cullen,2 Neil McCluney2 1Northern Ireland Medical and Dental Training Agency, Belfast, 2Head and Neck Unit, Altnagelvin Area Hospital, Derry, Northern Ireland, UK Introduction: Up to 5% of all children have prominent ears. Psychological distress and bullying adversely affect these children and can cause significant social exclusion. In times of austerity, cosmetic procedures such as surgical correction of prominent ears are felt to be an unnecessary cost to the health service. Materials and methods: A retrospective case note review of all patients undergoing pinnaplasty was undertaken. Postoperative outcomes were compared against the Royal College of Surgeons of England standards. The Glasgow Benefit Inventory, a validated post-intervention questionnaire, was then posted out to all patients. Results: A total of 72 patients were identified. Average age at procedure was 13 years. Eleven patients were above the age of 19 years. Twenty-eight patients were male and forty-four female. Sixty-two cases underwent bilateral pinnaplasty. No patients developed hematoma, and there were no readmissions within 30 days of surgery. Twenty-nine patients responded to the questionnaire (40%, of whom 27 reported a positive impact on their psychosocial well-being with a mean score of 36. Conclusion: Pinnaplasty offers patients an opportunity to alleviate the psychological distress of bullying and harassment secondary to the appearance of prominent ears.

    The increasing use of geographic information systems (GIS) in epidemiological population studies requires careful attention to the methods employed in accomplishing geocoding and creating a GIS. Studies have provided limited details,hampering the ability to assess validity of spatial data. The purpose of this paper is to describe the multiphase geocoding methods used to retrospectively create a GIS in the Jackson Heart Study (JHS). We used baseline data from 5,302 participants enrolled in the JHS between 2000 and 2004 in a multiphase process to accomplish geocoding2 years after participant enrollment. After initial deletion of ungeocodable addresses(n=52), 96% were geocoded using ArcGIS. An interactive method using data abstraction from participant records, use of additional maps and street reference files,and verification of existence of address, yielded successful geocoding of all but 13 addresses. Overall, nearly 99% (n=5,237) of the JHS cohort was geocoded retrospectively using the multiple strategies for improving and locating geocodable addresses. Geocoding validation procedures revealed highly accurate and reliable geographic data. Using the methods and protocol developed provided a reliable spatial database that can be used for further investigation of spatial epidemiology. Baseline results were used to describe participants by select geographic indicators, including residence in urban or rural areas, as well as to validate the effectiveness of the study's sampling plan. Further, our results indicate that retrospectively developing a reliable GIS for a large, epidemiological study is feasible. This paper describes some of the challenges in retrospectively creating a GIS and provides practical tips that enhanced the success.

    To document subtype-specific clinical features of lymphoma of the eyelid, and their effect on patient outcome. Retrospective observational case series. Patient data were collected from 7 international eye cancer centers from January 1, 1980 through December 31, 2015. The cases included primary and secondary lymphomas affecting the eyelid. Overall survival, disease-specific survival (DSS), and progression-free survival were the primary endpoints. Eighty-six patients were included. Mean age was 63 years and 47 (55%) were male. Non-Hodgkin B-cell lymphomas constituted 83% (n = 71) and T-cell lymphomas constituted 17% (n = 15). The most common subtypes were extranodal marginal-zone lymphoma (EMZL) (37% [n = 32]), follicular lymphoma (FL) (23% [n = 20]), diffuse large B-cell lymphoma (DLBCL) (10% [n = 9]), mantle cell lymphoma (MCL) (8% [n = 7]), and mycosis fungoides (MF) (9% [n = 8]). EMZL had a female predilection (69% [22 of 32]), whereas MCL (71% [5 of 7]) and MF (88% [7 of 8]) had a male predominance. MCL (57% [4 of 7]), DLBCL (56% [5 of 9]), and MF (88% [7 of 8]) were frequently secondary lymphomas. Localized EMZL and FL were mostly treated with external beam radiation therapy, whereas DLBCL, MCL, and high Ann Arbor stage EMZL and FL were frequently treated with chemotherapy. DLBCL and MCL had a poor prognosis (5-year DSS, 21% and 50%, respectively), whereas EMZL, FL, and MF had a good prognosis (5-year DSS, 88%, 88% and 86%, respectively). Lymphoma of the eyelid consists mainly of the lymphoma subtypes EMZL, FL, DLBCL, MCL, and MF. High-grade DLBCL and MCL, as well as MF, are frequently secondary eyelid lymphomas. The main predictor of outcome was the histologic subtype: EMZL, FL, and MF had a significantly better prognosis than MCL and DLBCL. Copyright © 2017 Elsevier Inc. All rights reserved.

    Biliary tract disease is a common non-obstetric surgical presentation during pregnancy. Although small international series demonstrate favourable outcomes following laparoscopic cholecystectomy (LC) during pregnancy, there is a paucity of Australian data to complement these findings. Between 1st January 2003 and 30th June 2013, all patients undergoing planned LC during pregnancy at Western Health were retrospectively identified. Twenty-two patients underwent planned LC with 3 (13%) cases converted to open surgery. The median maternal age was 31 years (27.8-36) with an estimated median gestational age (EGA) of 19.5 weeks (16.5-23.5). Eighteen (82%) cases were performed during the second trimester. Nine (40%) patients had 2 or more hospital admissions for similar presentations. Twelve (54%) were performed as index cases. Operative indications included 12 (54%) with recurrent biliary colic, five (22%) with acute cholecystitis and 3 (14%) with gallstone pancreatitis. Median operating time for completed LCs was 65 min (60-95). Intra-operative cholangiogram was performed in seven (32%) cases, 5 (71%) of which employed protective uterine lead shielding. There was no fetal loss or uterine injury. Median hospital stay was 3 days (2-7) for completed LCs. Major morbidity occurred in 2 (10%) completed LCs that required a return to theatre. Five (23%) births were lost to follow up. The median time to delivery post-surgery was 13 weeks (11-15). Two (12%) preterm deliveries occurred, with subsequent neonatal complications. Antenatal laparoscopic cholecystectomy demonstrated comparably safe outcomes. Increasing its utilization to manage symptomatic cholelithiasis during pregnancy may be considered.

    Full Text Available The aim of this paper is to present some results of a comparative study between the politeness strategies that two Spanish and two Brazilian professors would use, both in Portuguese and Spanish, in twelve hypothetical situations presented on a social behavior questionnaire. This work is based on a previous study published by Piatti (2003 in Argentina, where the author observed some pragmatic differences between a group of students of Spanish as a foreign language and a group of native speakers of the language. With her hypotheses as a starting point, the scope was moved to a small group of people with high communicative competence in both languages, in order to give a different insight on of the pragmatic differences that exist between Brazilians and the Spanish. Based on the findings, we have tried to establish some intercultural differences among the politeness strategies used in Brazil and in Spain.

    The state of mental health of the population is considered to be an important and essential component of public health. Depression is the mental disorder with greatest prevalence in several countries around the world. This was a nationwide Brazilian survey with household-based interviews. The sampling process was at random and cluster-based, and performed in three stages: census tracts, households and individuals. One inhabitant aged ≥18 years was selected per household. Individuals at greater risk of depression were identified through the Patient Health Questionnaire-9 (PHQ-9) algorithm, which uses internationally accepted diagnostic criteria. All analyses took into account sample weights. A total of 60,202 individuals were evaluated and the prevalence of positive screening for depression was 4.1% (95% CI: 3.8-4.4%). After adjustments for potential confounding factors, depression was found to be greater among women, individuals aged either 40-59 years or 80 years or over, individuals living in urban areas, those with lower educational level, smokers, and among individuals with arterial hypertension, diabetes and heart disorders. Skin colour, marital status and alcohol abuse were not associated with depression. Characteristics of respondents and non-respondents in the sample could not be compared because data about non-respondents was not available. The prevalence of positive screening for depression in Brazil was similar to other studies conducted worldwide. In Brazil, this proportion reflects a considerable absolute number of people with greater risk of depression (≈5.5 million) that may require adequate management through the health system and services.

    Full Text Available Objective: Erythema nodosum (EN is the most common type of septal panniculitis. Although triggering factors of EN are drugs, infections, malignancies, inflammatory diseases however disease is idiopathic in 32-72%. Factors are changing from region to region and from country to country. In this study, our aim was to investigate the etiologic factors and to evaluate the clinic and laboratory findings of EN.Methods: Sixty-six patients who were histopathologically diagnosed as EN in our department between 2005 and 2010 were included to this study. Demographic data and treatment were evaluated.Results: Fifty-two of 66 patients had underlying etiologic factors (Group 1 and 14 of were idiopatic (Group 2. Most common etiologic factor was Behçet’s disease (n=15, and followed by drug (n=13, sarcoidosis (n=10, upper respiratory tract infection (n=6, autoimmune disease (n=4, pregnancy (n=2, tuberculosis (n=2 in decreasing frequencies. In our study malignancy and inflammatory bowel disease are not appointed.Conclusion: Behcet’s disease is a rare cause of EN. In other studies in our country the idiopatic group was in majority. In our study because of finding the common etiologic factor as Behçet’s disease due to being of Behçet’s disease high prevalance (11-42/10000 in our country and existence of Behçet’s disease center in our faculty

    2013-01-01

    The aim of this study was to review cases of odontogenic tumors diagnosed in two pathology centers in Tehran, Iran, during a 10-year period. Patients' records were seen at two teaching pathology Centre's of Shahid Beheshti University between the months of March 2000 to 2010 with histologic diagnosis of any type of odontogenic tumors. The records were analyzed for frequency, age, sex, site, as well as clinical, radiographic and histopathologic findings. Of 30706 biopsies, 4767 (15.5%) cases were diagnosed as oral and maxillofacial lesions. Among these, 720 cases were tumoral with 188 (26.1%) cases of odontogenic tumors. Tumors with odontogenic epithelium origin formed 70.2% of total numbers of odontogenic tumors. Mixed odontogenic tumors and tumors of odontogenic ectomesenchyme comprised 12.2% and 17.5% of the cases respectively. Ameloblastoma, with a frequency of 62.2% was the most common tumor in this review which was followed by odontoma and odontogenic myxoma. Although there are few studies on odontogenic tumors in literature, the comparison of our results with existing data shows significant differences in the distribution of tumors and age of patients, which may be due to ethnic features and geographic distribution of patients. Future studies on other ethnic groups are essential for further clarification of the findings in this research.

    Salivary gland tumours are an important part of the Oral and Maxillofacial Pathology, unfortunately, only few studies on these tumours have been done in Latin-American population. The aim of this study was to compare demographic data on salivary gland tumours in a Mexican sample with those previously published from Latin American and non-Latin American countries. All cases of salivary gland tumours or lesions diagnosed in our service were reviewed. Of the reviewed cases,67 were confirmed as salivary gland tumours. Out of these 64.2% were benign neoplasms, 35.8% were malignant and a slight female predominance (56.7%) was found. The most common location was palate followed by lips and floor of the mouth. Mean age for benign tumours was 40.6 years with female predominance (60.5%). Mean age for malignant tumours was 41 years and female predominance was found again. Palate followed by retromolar area were the usual locations. Pleomorphic adenoma (58.2%), mucoepidermoid carcinoma (17.9%) and adenoid cystic carcinoma (11.9%) were the more frequent neoplasms. All retromolar cases were malignant and all submandibular gland tumours were benign. We found a high proportion of salivary gland neoplasms in children. Our results showed that differences of the studied tumours among our sample and previously reported series exist. These differences can be related to race and geographical location.

    The study aimed to determine the incidence of congenital infection by Toxoplasma gondii and to describe neonatal and maternal characteristics regarding newborn infants treated at a teaching hospital in the town of Passo Fundo, State of Rio Grande do Sul, Brazil. Cord blood samples collected from 1,250 live newborns were analyzed. The laboratory diagnosis was established by the detection of Toxoplasma gondii IgM using an enzyme linked fluorescent assay. Gestational age, intrauterine growth, anthropometric measures, and prenatal characteristics were assessed. The incidence of congenital toxoplasmosis at birth was 8/10,000 (95%CI 0.2-44.5). Mean birthweight was 3,080 +/- 215.56 grams and mean gestational age was 38.43 +/- 1.88 weeks. With regard to prenatal care, 58% of the pregnant patients visited their doctors five times or more and 38.9% were serologically tested for toxoplasmosis in the first trimester of pregnancy. The incidence of congenital toxoplasmosis was similar to that found in most studies conducted in our country and abroad. Our study sample is representative of the town of Passo Fundo and therefore it is possible to consider the frequency observed as the prevalence of the disease in this town during the study period.

    To study the prevalence of connective tissue disorders and identify the epidemiological profile of the population from the northern and northeastern regions of Brazil. All patients admitted to the general medical ward at Getulio Vargas Hospital were screened through history and physical examination for the existence of known, suspected or possible connective tissue disorder. A total of 120 patients were enrolled in the study - 61 (50.8%) with systemic lupus erythematosus (SLE), 41 (34.2%) with rheumatoid arthritis (RA), 16 (13.3%) with systemic sclerosis (SS), one (0.8%) with mixed connective tissue disease (MCTD) and one (0.8%) with polymyositis (PM). Women accounted for (104) 86.7% of the participants and (83) 70.9% were non-Caucasians. The mean age was 36.8 years. Alopecia was the most frequent symptom (55/46.6%), followed by other cutaneous lesions (50/42.4%), dyspnea (47/39.8%) and chest pain (39/33.0%). The most frequent rheumatologic disorder encountered in our hospital-based study population was systemic lupus erythematosus, which is contrary to findings of the majority of studies performed in this country.

    Rhizarthrosis, or osteoarthritis of the base of the thumb, is a common condition affecting 10-30% of the population over the age of 60. Whether it is an occupational disease has been the subject of debate as epidemiological studies on the correlation between physical stress and the presence of rhizarthrosis have shown conflicting results. To study the correlation between the prevalence of rhizarthrosis and the time spent by employees manually processing banknotes at the National Bank of Belgium (NBB). We followed NBB employees currently or previously holding job titles involving the manual or automated processing of banknotes. Each participant's job history was carefully reconstructed and the number of months holding certain job titles determined. Each participant was clinically and radiologically examined for the presence of rhizarthrosis in both hands. Its presence was scored by a combination of clinical and radiological criteria. There were 195 participants. The prevalence of rhizarthrosis was 27% in women (mean age: 52.3 ± 4.4 years) and 17% in men (mean age: 53.2). The odds ratio (OR) for rhizarthrosis after 10 years' full-time overall exposure was significantly higher [OR 10 years: 1.53 (1.03-2.28)]. However, one particular job, 'manual counting', described by participants as highly straining and severely taxing on the thumbs, did not show a significantly higher prevalence of rhizarthrosis. Our study confirmed the correlation between the presence of rhizarthrosis and age, gender and general manual labour, in particular banknote processing, but found no link with one specific job-manual counting.

    Hyperemesis gravidarum (HG) is characterized by severe intractable nausea and vomiting in pregnancy leading to electrolyte imbalance, ketonuria, and weight loss. The cause is unknown. This study sought to investigate the prevalence and characteristics of HG in the Western Galilee in two ethnic populations and to estimate its economic burden. Data on ethnicity, age, gestational age, number of pregnancies, and length of hospitalization were collected from the medical files of all women with HG admitted to the Galilee Medical Center in 2010-2013. Findings were compared between Arabs and Jews. Prevalence was assessed relative to total number of births. Economic burden was assessed by cost of hospitalization and work days lost. The cohort included 184 women, 124 Arabic (67.4 %) and 60 Jewish (32.6 %). There were 13,630 births at the medical center during the study period, for a calculated prevalence of HG of 1.2 %. There was no difference in the relative proportions of Arabs and Jews between the cohort and the total women giving birth at our center. Mean patient age was 27.2 years, gestational age 9.3 weeks, parity 2.35. Mean age was significantly higher in the Jewish group. There were no significant between-group differences in the other clinical parameters. Mean number of hospitalization days was 2.24 days, and of additional rest days prescribed, 4.62. The calculated annual cost of HG was 452,943.42 NIS (120,144.14 USD), crudely extrapolated to a nationwide cost of 15-20 million NIS (5,300,000 USD). The prevalence and characteristics of HG are similar in the Arabic and Jewish populations of northern Israel. Mean gestational age at admission for HG was lower in our study than earlier ones, probably owing to the universal health care provided by law in Israel. HG prevalence was twice that reported previously in southern Israel but still within the range observed in other world regions. The socioeconomic differences between Arabs and Jews in the Galilee are smaller

    1983-01-01

    One hundred and three women who were known to have complained of menorrhagia at some time in their lives were compared with a control group drawn from the practice's age-sex index. The results indicated that the women in the menorrhagia group were more likely to have had antidepressant medication prescribed for them at some time in their lives than the women in the control group. Furthermore, their case folders were thicker than those of the controls. The age at which menorrhagia was first reported was the only factor studied which was associated with increased likelihood of hysterectomy. ImagesFigure 2Figure 3. PMID:6644677

    Full Text Available BACKGROUND Fractures of the acetabulum occur primarily in young adults as a result of high-velocity trauma and in old age even with trivial trauma. Anatomic reduction and stable fixation of the fracture such that the femoral head is concentrically reduced under an adequate portion of the weight bearing dome of the acetabulum is the treatment goal in these difficult fractures. The aim of the study is: 1. To study the outcome after reconstruction of fracture of acetabulum. 2. To study the postoperative complications and failures. MATERIALS AND METHODS The present study was carried out from March 2015 to September 2016 at Orthopaedics Department, Aarupadai Veedu Medical College and Hospital. During this period, 25 patients of acetabular fracture (20 males and 5 females were managed in our hospital surgically. The indication for surgery in acetabulum fracture was decided according to displacement of fracture and it is decided by measuring the roof arc measurement developed by Matta. If the fracture has been displaced medially or anteriorly or posteriorly to 45° or 25° or 70°, then the fracture should be taken for surgery. All our patients were operated under general anaesthesia with plate and screws (reconstruction or dynamic compression. Some patients were treated with interfragmentary screws. RESULTS Our results were evaluated on the basis of both clinical and radiologic criteria as well as according to fracture type. 1,2,3 Radiologic evaluation showed 76% of excellent and good results and 24% of fair or poor results, while the functional outcome assessment according to d’Aubigne postal scoring and Harris hip score in acetabulum fracture, excellent functional outcome in 13 patients with posterior column acetabulum fracture and fair or poor result in 5 patients. In anterior column acetabulum fracture, 7 patients had excellent functional outcome (44%. Similar results have been reported by Letournel 2 and Matta. 4,3,5 If results were associated

    Cerebral venous thrombosis (CVT) is a rare origin of stroke, the clinical presentation and etiologies vary. The prognosis is shown to be better than arterial thrombosis. Magnetic Resonance Imaging (MRI) and MR Venograpgy (MRV) are currently important tools for the diagnosis. We studied 30 cases of CVT diagnosed in the department of neurology at the University Hospital of Fez (Morocco). Patients diagnosed with CVT signs between January 2003 and October 2007 were included in the study. Cerebral CT-scan was performed in 27 cases (90%) while the MRI examination was done in 18 patients (67%); and most patients (90%) received anticoagulant therapy. The mean age of our patients was of 29 years (age range between 18 days and 65 years). A female predominance was observed (70%). The clinical presentation of patients was dominated by: headache in 24 cases (80%), motor and sensory disability in 15 cases (50%), seizures in 10 cases (33%), consciousness disorder in 10 cases (33%). CVT was associated to post-partum in 10 cases (33%), infectious origin in 8 cases (26%), Behçet disease in 2 cases (7%), pulmonary carcinoma in 1 case, thrombocytemia in 1 case and idiopathic in 7 cases (23%). The evolution was good in 20 cases (67%), minor squelaes were observed in 6 patients (20%), while major squelaes were observed in 2 cases. Two cases of death were registered. The CVT is a pathology of good prognosis once the diagnosis is promptly established and early heparin treatment initiated. PMID:25317229

  4. A retrospective study of the orthopoxvirus molecular evolution.

    2012-12-01

    The data on the structure of conserved genes of the Old and New World orthopoxviruses and unclassified Yoka poxvirus were used for a Bayesian dating of their independent evolution. This reconstruction estimates the time when an orthopoxvirus ancestor was transferred to the North American continent as approximately 50 thousand years ago (TYA) and allows for relation of this time interval with the global climate changes (with one of the short-term warmings during the Last Ice Age). The onset of the Yoka poxvirus evolution was assessed as approximately 90TYA. Availability of a large number of genome sequences of various cowpox virus strains provided for a comprehensive analysis of the orthopoxvirus evolutionary history. Such a study is especially topical in view of the postulated role of this virus in the evolution of various orthopoxviruses, namely, as an progenitor virus. The computations have demonstrated that the orthopoxviruses diverged from the ancestor virus to form the extant species about 10TYA, while the forbear of horsepox virus separated about 3TYA. An independent evolution of taterapox, camelpox, and variola viruses commenced approximately 3.5TYA. Study of the geographic distribution areas of the hosts of these three orthopoxviruses suggests the hypothesis on the region of their origin. It is likely that these viruses first emerged in Africa, in the region of the Horn of Africa, and that the introduction of camels to East Africa induced their divergent evolution.

    2007-02-01

    Colorectal carcinoma, a common adult malignancy, has an estimated childhood incidence of 0.3 to 1.5/million in Western countries and 0.2/million in Israel. Diagnosis is difficult because adult screening measures are unfeasible in children. The tumor is frequently associated with predisposing genetic factors, aggressive biological behavior, and poor prognosis. The aim of this multicenter study was to document the clinical profile, treatment and prognosis of colorectal carcinoma in children in Israel. The clinical, laboratory, therapeutic, and prognostic parameters of all 7 children from 4 medical centers in Israel who were diagnosed with colorectal carcinoma over a 25-y period were reviewed. Patients presented with rectal bleeding (4 of 7), abdominal pain (2 of 7), and abdominal distension (2 of 7). Average time to diagnosis was 6 months. Six patients underwent surgery (1 refused), and 5 received chemotherapy. Histopathological studies showed poorly differentiated mucinous adenocarcinoma, signet-ring type, in 4 cases, moderately differentiated adenocarcinoma in 2, and well-differentiated carcinoma in 1. Three patients died of the disease, 2 shortly after diagnosis. One patient with recurrent metastatic disease was lost to follow-up. Colorectal carcinoma in children is characterized by aggressive tumor behavior and delayed diagnosis, resulting in a worse prognosis than in adults. Heightened physician awareness of the possibility of this disease in children, with special attention to adolescents with predisposing factors and rectal bleeding, could help to improve outcome.

    The aims of current study were to determine whether childhood maltreatment contributes to the occurrence of major depressive disorder (MDD) with bipolarity or suicidality. In total, 132 outpatients diagnosed with MDD between 2014 and 2015 on the medical records were included. The subjects were divided into two groups according to the presence of childhood maltreatment (CM group) and no childhood maltreatment (NCM group). Depression severity and bipolarity were identified using Beck Depression Inventory (BDI) and the Korean version of Mood Disorder Questionnaire (K-MDQ) respectively on the medical records. In addition, the baseline loud dependence of auditory evoked potentials of 36 patients on medical records were analyzed. The mean total BDI, BDI item 9 (suicide ideation), and total K-MDQ score were significantly higher in the CM group than the NCM group. The number of subjects with bipolarity was significantly higher in the CM than in the NCM group. Furthermore two thirds subjects experienced the significant maltreatment during childhood. The central serotonergic activity of the CM group was also lower than that of the NCM group. The findings of this study support that there is a relationship between childhood maltreatment and bipolarity or suicidality in patients with MDD.

    Full Text Available The study described perceived differences in the choice of child rearing practices aimed at correcting children’s inappropriate behaviors as remembered by the participants at young adulthood. The sample consisted of 207 students of under-graduate studies of the University of Novi Sad. The most of the participants does not have children and they grew up in complete families. On the Dimensions of Discipline Inventory (A (DDI-A, Straus, Fauchier, 2007, the participants estimated the experience and methods of disciplining which were used by their parents during their childhood. The participants describe uniform discipline behaviors of their parents regarding the estimated discipline techniques. These behaviors are dominated by the punishing ones, and the differences between fathers and mothers are visible in a stronger tendency to describe fathers as the ones who use corporal punishment, abolish privileges and give restorative tasks. The described discipline techniques for both fathers and mothers remain stable and similar, regardless of the socio-demographic characteristics of the families as family completeness, work experience and level of education of the parents, as well as estimated economic status of the family.

    Over the last decade, laparoscopic hepatic surgery (LHS) has been increasingly performed throughout the world. Meanwhile, ambulatory surgery has been developed and implemented with the aims of improving patient satisfaction and reducing health care costs. The objective of this study was to report our preliminary experience with ambulatory minimally invasive LHS. Between 1999 and 2014, 172 patients underwent LHS at our institution, including 151 liver resections and 21 fenestrations of hepatic cysts. The consecutive series of highly selected patients who underwent ambulatory LHS were included in this study. Twenty patients underwent ambulatory LHS. Indications were liver cysts in 10 cases, liver angioma in 3 cases, focal nodular hyperplasia in 3 cases, and colorectal hepatic metastasis in 4 cases. The median operative time was 92 minutes (range: 50-240 minutes). The median blood loss was 35 mL (range: 20-150 mL). There were no postoperative complications or re-hospitalizations. All patients were hospitalized after surgery in our ambulatory surgery unit, and were discharged 5-7 hours after surgery. The median postoperative pain score at the time of discharge was 3 (visual analogue scale: 0-10; range: 0-4). The median quality-of-life score at the first postoperative visit was 8 (range: 6-10) and the median cosmetic satisfaction score was 8 (range: 7-10). This series shows that, in selected patients, ambulatory LHS is feasible and safe for minor hepatic procedures. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    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.

    The functionality of cryopreserved parathyroid autotransplantation (CPAT) has been evaluated in few studies, mostly conducted by experienced single-institution centers that have reported different success rates ranging from 17% to 83%. In France, CPAT are rare and their functionality has never been evaluated. Moreover, French tissue banks are facing an accumulation of ungrafted samples. The aim of our work was to evaluate the implantation rate of cryopreserved parathyroid samples and the functionality of CPAT in a multicenter study. Data from 9 French tissue banks were analyzed. CPAT functionality was defined as fully functional (normal parathyroid hormone [PTH] and calcium levels without treatment), partially functional (normal PTH levels but need for treatment to maintain normocalcemia), and nonfunctional (low PTH levels and need for treatment). For dialyzed patients, CPAT was considered nonfunctional if the PTH level in the nongrafted arm was less than 20 pg/mL, partially functional if the PTH level was between 20 and 50 pg/mL, and fully functional if the PTH level was between 50 and 300 pg/mL. The 9 centers had cryopreserved 1376 samples of parathyroid tissue and only 22 (1.6%) had been autografted in 20 patients (65% renal hyperparathyroidism, 20% multiple endocrine neoplasia type 1, 15% "other") by 12 different surgical teams. The median duration of storage was 11.1 months (range, 0.4-28.5). Only 2 autografts (10%) were fully functional, 2 (10%) were partially functional, and 17 (80%) were nonfunctional at 26 months median follow-up. The reimplantation rate is low, and the functionality of CPAT is less than those published by experienced centers. Logistical and technical problems occurring in less experienced centers are probably the main reasons for nonfunctioning implants. Considering the results of this study, we suggest that cryopreservation of parathyroid glands should be abandoned when not performed in very large experimented centers, that CPAT should

    Scorpions, especially in urban areas, due to the great demographic density and confrontation possibility, represent a risk to the public health. Tityus serrulatus is the most important species, causing the highest number of accidents. This study intended to raise epidemic data and the occurrence of scorpionism in Belo Horizonte, between 1990 and 1997. The data were gathered from the records of Hospital de Pronto Socorro João XXIII. Of the 3265 cases, most occurred in 1996, of which six were fatal accidents. With greater incidence in January, the male sex, superior members and 25-65 year-old age group were the most affected. The results constitute an important tool for the control of scorpionism, since they delimit the areas most involved and the victims' profile, enabling more efficient and durable prevention educational campaigns.

    GIS (Geographic Information System) is a useful tool that aids and assists in health research, health education, planning, monitoring and evaluation of health programmes that are meant to control and eradicate certain life threatening diseases and epidemics. HIV/AIDS is one such epidemic that poses a serious challenge and threatens the overall human welfare. This communication is an attempt to link and understand the health scenario in a GIS context with emphasis on HIV/AIDS. Various GIS based functionalities for health studies and their scope in analyzing and controlling epidemiological diseases are explored. Overall scenario of the spread of HIV/AIDS around the world is presented along with the Indian perspective. Finally, we conclude with the general management problems, issues and challenges related to HIV/AIDS prevailing in India.

    Dilated cardiomyopathy (DCM) is the most common myocardial disorder of dogs, typically affecting large and giant breeds. The purpose of this study was to describe the clinical features of DCM in standard schnauzers. Medical records for 15 standard schnauzers diagnosed with DCM were reviewed. The median age at diagnosis of DCM was 1.6 yr, with all dogs developing left-sided congestive heart failure (CHF). The median age of onset of CHF was 1.6 yr, and was significantly shorter in males (1.5 yr) than for females (2.35 yr). The median survival time after diagnosis of CHF was 22 days, and was shorter in males (13 days) than females (62 days). The occurrence of early onset DCM in multiple closely related standard schnauzers suggests a familial predisposition in this breed. Pedigree analysis confirmed common ancestry for all DCM affected dogs with a most likely autosomal recessive mode of inheritance.

    Study of the quality of life of 42 patients who underwent a lipofilling in our institution between 2009 and 2010. Analysis of cosmetic outcomes, side effects, emotional life and preoperative information received by a cohort of 42 patients contacted by anonymous questionnaires. Comparisons between patients with a single prothesis, latissimus dorsi flap with prothesis, autologous latissimus dorsi flap and rectus abdominal flap. The response rate was 56% (42 patients). The average volume of fat injected was 80mL. The aspect of the reconstructed breast and the harmony between two breasts were better after lipofilling (P=0.0001, P=0.0005). The evolution of the aesthetic result is satisfying for 64.1% of the patients. In 29% of cases, patients noticed adhesions at the injection site. Apprehension to touch the reconstructed breast and to wear a swimsuit decreases after lipofilling (P=0.0345;P=0.0284). All patients declared to be satisfied with the presurgery information. Half of the patients declare that the final result corresponds to their wishes. The side effects of lipofilling were studied from an oncological point of view. Less publications describe the patients quality of life after lipofilling. This surgery improves the breast reconstruction results and helps patients in a social, affective and aesthetic way. Overall, lipofilling improves more consistency in patients reconstructed by single prothesis and improves more appearance in patients reconstructed by single flap. Lipofilling improves significantly patients' quality of life. A clinical research protocol (GRATSEC) is currently underway to extend its indications. The lipofilling should not replace a bad indication of breast reconstruction. Copyright © 2013. Published by Elsevier SAS.

    Full Text Available To review clinical characteristics of pigmented villonodular synovitis (PVNS in China.Electronic medical records (EMR of four Chinese institutes were queried for patients with histologically proven PVNS between January 2005 and February 2014. Their data were collected including gender, age at diagnosis, clinical presentation, affected site, symptom duration, comorbidities, treatment strategy, recurrence and routine laboratories.A total of 237 patients with biopsy-proven PVNS were investigated. The gender ratio was 1.35 for a female predominance (101 males and 136 females. The average age was 36 years (range, 2 to 83 years. The median delay from initial clinical symptom to diagnosis was 18 months. Main affected areas were the knee (73.84% and the hip (18.14%. Forty patients had a clear history of joint trauma. Six patients were concurrently diagnosed with PVNS and avascular necrosis (AVN. Five patients suffered from PVNS following implantation of orthopaedic devices including artificial prosthesis, plate and wire. One hundred and twenty-nine patients underwent arthroscopic synovectomy and 108 open synovectomy. Altogether 48 patients (26 males and 22 females had recurrence of disease. The relapse rate was 24% (knee and 6.98% (hip, 20.93% (open surgery and 19.44% (arthroscopy, respectively. Erythrocyte sedimentation rate (ESR and C-reactive protein (CRP rate were elevated in 45.83% and 38.41% of the patients respectively.To our knowledge, this study is the largest sample size of PVNS patients reported as well as the largest sample of PVNS with concurrent AVN reported to date. Our outcomes suggest that PVNS shows a female predominance, occurs mostly between 20-40 years and favors the knee and hip. Recurrence is frequent, particularly in the knee. Serum ESR and CRP may be elevated in some patients. Additionally, the present study supports the theory of an association between PVNS and orthopedic surgery, which is not limited to joint replacement.

    The purpose of this study is to evaluate the clinical results of patients who received surgical treatment for chronic recurrent dislocations (CRD). In our clinical practice CRD patients were classified into 5 types depending upon their aetiology. These patients were treated by two different surgical techniques, eminectomy or augmentation of the eminence by autograft depending on their classification. Nineteen patients with CRD attended the clinic for surgical treatment. Patients were classified accordingly into 5 types of CRD. Eminoplasty was used in the treatment of twelve patients with type I and II disease. An oblique osteotomy of the eminence was carried out. Harvested chin graft was contoured to a wedge form and inserted tightly into the osteotomy site. The augmentation of the eminence was provided by an inlay cortical bone graft without using any of the conventional fixation materials. The remaining 7 patients with type III, IV and V disease were treated by eminectomy. The factors evaluated were pre- and post-operative maximal incisor opening, sex, age, number and type of previous operations, cause and type of the CRD, and the previous treatment of the patients. The survey is based on nineteen patients who were treated in the same department. Patients age ranged from 22 to 80 years. Females are dominated in the study. The follow-up period ranged from 1 to 12 years. Free excursions of the condyles were achieved in the patients treated by two different techniques. On the other hand, maximum interincisal openings were higher in the patients treated by eminectomy when compared with the patients who had eminoplasty. So far as the quality of life for the patients with CRD is concerned, the most appropriate technique (whether it be to confine the condyle or allow its free movement) to be employed should be decided by following an comprehensive evaluation of the patients' history.

    Full Text Available Background: Gestational trophoblastic disease (GTD defines a heterogenenous group ofinterrelated lesions that arise from the trophoblastic epithelium of the placenta. There are severalhistologically distinct types of GTD: hydatiform mole (complete or partial, persistant/invasivegestational trophoblastic neoplasia (GTN, choriocarcinoma and placenta site trophoblastictumors. The aim of this study was to determine the frequency and risk factors of GTD amongwomen admitted to Imam Khomeini Hospital in Ahvaz, Iran.Materials and Methods: This was a cross-sectional study conducted at Imam KhomeiniHospital in Ahvaz, Iran. All hospital records related to GTD (132 from 1996 until 2006 werereviewed. Demographic and histo-pathologic characteristics were extracted. Chi-square andFisher-exact tests were used to analyze all variables. P ≤ 0.05 was considered statisticallysignificant. SPSS, version 11 was used for statistical analysis.Results: The mean age of patients was 27.6 years. Most patients who presented with GTDwere of ages 18-35 years (71.3%. There was no relationship between age and hydatiformmole during the reproductive years. There were 28 (18.9% patients over the age 40, of which18 (15.90% of these had a complete hydatiform mole. Within this group, 9 (6.8% changedto a persistent mole. There was a significant relationship between age over 40 and completemole (p<0.02. The percentage of patients with blood groups A and O was the same (37.9%.There was a significant relationship between blood groups (O+ and A+ and complete mole(p<0.05.Conclusion: The most common age range for hydatiform mole was 18-35 years. Women overthe age of 40 had a more complete hydatiform mole, which is similar to the other countries.Age and blood group are two risk factors for hydatiform mole.

    Full Text Available The spleen of dogs is frequently affected by disorders that vary from local and systemic origin. The difficulty in associating clinical and gross findings contributes for the choice of total splenectomy as the main treatment, leading to an impairment of the immune and hematopoietic functions. The aim of this study was to evaluate the pathological findings in the spleen of splenectomized dogs during 2008 to 2014 at a Veterinary Teaching Hospital. From the 71 cases analyzed, 97% (69/71 of the dogs were submitted to total splenectomy and 3% (2/71 to partial splenectomy. In 45 (63.4% of these cases, the histopathological diagnosis was non-neoplastic alterations; only 36.6% (26/71 had a splenic neoplasia. The main non-neoplastic lesions observed were nodular hyperplasia 24.4% (11/45, infarction 22.3% (10/45, and hematoma 20% (9/45. The most frequent tumors were hemangiosarcoma 50% (13/26, histiocytic sarcoma 23% (6/26, and lymphoma 11.5% (3/26. The clinical methods used to diagnose splenic lesions were ultrasonography 88% (63/71, radiography 2.8% (2/71 and exploratory laparotomy 4.2% (3/71. In 4.2% (3/71 the spleen changes were observed during the therapeutic ovariohysterectomy.

    Lip cancer is the most frequent malignant neoplasm of the oral cavity; however, there is no information available on the incidence of this type of cancer in Mexico. This study provides information about the clinico-pathological features of lip cancer patients admitted at a cancer hospital in Mexico City during an 11-year period and describes the treatment modalities performed and their results. A total of 113 patients were studied. There were 74 men (65.5%) and 39 women (34.5%), ranging in age from 14 to 106 years (mean 70 years). In 53 cases (46.9%) an association was found between the disease and chronic sun exposure. Additionally, positive smoking antecedents were recorded in 58 cases (51.3%). As 15 patients were followed for less than 1 month, they were excluded for further analysis. There were 82 cases (83.7%) of squamous cell carcinoma, 10 (10.2%) basal cell carcinomas, and one case (1%) each of adenocarcinoma NOS, melanoma, adenoid cystic carcinoma, Merkel cell carcinoma, lymphoepithelioma and angiosarcoma. We observed an incidence of malignant neoplasms in the upper lip of 33.7%, which is higher than most of the published series and may be due to the fact that in this series we included all histological types of lip cancers. Fifty percent of the cases were found in stages III and IV. Cervical lymph node metastases were found in 21% of patients with no previous treatment, and they developed in 5.3% after treatment. Our data suggest that tumoral size is directly related to the possibility of developing node metastases, as none of them occurred in patients T1, whereas 10 (62.5%) of the patients in T4 presented them. Seven deaths were documented (7.1%), five of which corresponded to squamous cell carcinoma, one to Merkel cell carcinoma, and one to adenocarcinoma. Deaths were directly related to the disease in six cases, and one patient died due to surgical complications. Distant metastases were found in only two patients, one of which coursed with an

    Symptomatic Tarlov cysts are a common cause of chronic pain. Many methods have been reported to treat this disease, with variable results. Most previous reports concerning the treatment methods of symptomatic Tarlov cysts were either sporadic case reports or series of limited cases. This study aimed to further optimize the management for patients with symptomatic Tarlov cysts (TCs) by analyzing the results of 82 patients who were treated with different strategies. Three different strategies were applied to 82 patients with symptomatic TCs and their clinical effects were evaluated in 13 months to 12 years follow-up. A pain management practice, a medical center, major metropolitan city, China. From June 2003 to August 2015, a total number of 82 patients with symptomatic TCs were treated with 3 different methods (microsurgical cyst fenestration and imbrication, C-arm fluoroscopy guided percutaneous fibrin gel injection, and conservative management) in the first affiliated hospital of Chongqing Medical University. The pain severity was assessed according to visual analog scale (VAS), and imaging changes were evaluated by magnetic resonance imaging (MRI). Patient improvements in pain and neurologic function were evaluated during a follow-up the period of 13 months to 12 years. All the patients who underwent microsurgical cyst fenestration and imbrication had either complete (7 patients, 50%) or substantial (7 patients, 50%) resolution of their preoperative symptoms and neurological deficits. However, 3 patients (21%) had cerebrospinal fluid (CSF) leakage and 3 patients (21%) suffered from recurrent symptoms. In C-arm fluoroscopy guided percutaneous fibrin gel injection group, 34 patients (61%) had complete resolution and 22 patients had (39%) substantial resolution, and no CSF leakage or recurrence occurred. Only 3 patients (25%) got substantial resolution in the conservative management group, but 9 patients (75%) had aggravation. An observational study with a

Subjects and method: The records of all adolescent pregnancies (aged 13–19 years delivered at Sisli Hamidiye Etfal Research and Training Hospital, Istanbul, Turkey, over a period of two years were reviewed. Structured survey was conducted with adolescent mothers over the phone. Results: The incidence of adolescent pregnancy was 7.06%; 91.1% of the cases were reported to be married. Consanguineous marriage was found to be 27.6%. Maternal anaemia was detected in 43.1% of cases. Premature birth rate was 6.3%. The rate of Cesarean section was 31.8%. Adolescent mothers were categorized into two groups: 17 years and below and above 17 years. The maternal, natal and postnatal outcomes were not statistically different between the two groups. Conclusions: Health policies should be revised and improved to take the necessary steps for providing adequate health services for adolescents and for improving prenatal, natal and postnatal care of pregnant adolescents.

    Full Text Available Objective: The relationship between pregnancy outcomes and fetal gender is well reported from different areas in the world, but not from Africa. In this study, we try to understand whether the recorded phenomenon of association of adverse pregnancy outcomes with a male fetus applies to our population. Materials and methods: A total of 29,140 patient records from 2009 and 2010 were retrieved from Aljalaa Maternity Hospital, Tripoli, Libya. Analysis was carried out to find the correlation between fetal gender and different pregnancy outcomes. Results: A male fetus was associated with an increased incidence of gestational diabetes mellitus (odds risk 1.4, preterm delivery (6.7% for males, 5.5% for females, odds risk 1.24, cesarean section (23.9% for males, 20% for females, odds risk 1.25, and instrumental vaginal delivery (4.4% for males, 3.1% for females, odds risk 1.48, p<0.005. Preeclampsia was more frequent among preterm females and postterm males, p<0.005. It was also more frequent in male-bearing primigravids, p<0.01. Conclusion: We confirm the existence of an adverse effect of a male fetus on pregnancy and labor in our population. We recommend further research to understand the mechanisms and clinical implications of this phenomenon.

    The objective of this study was to develop an evidence-based airway management protocol for patients with acute tetraplegia. The method consisted of an analysis of the medical records of patients (September 1997–December 2002) with a spinal cord injury and a neurological deficit less than 8 weeks old. Of the 175 patients, 72 (41, 14%) were tracheotomised. This was influenced by the origin of the paralysis, Frankel score, and number of cervical spine operations, accompanying injuries and accompanying illnesses. Tracheotomy did not affect the duration of treatment, duration of ventilation or length of stay in the intensive care unit. The need for a tracheotomy was able to be predicted in 73.31% with neurological level, Frankel score and severity of accompanying injuries. In patients with acute tetraplegia, primary tracheotomy is indicated in sub C1–C3 with Frankel stage A/B, sub C4–C6 with Frankel stage A/B with trauma and accompanying injuries/accompanying illnesses, and in patients with complex cervical spine trauma that requires a combined surgical approach. In other patients, an attempt at extubation should be made. PMID:20179975

    Urticarial vasculitis is a subtype of vasculitis characterized clinically by urticarial lesions and histologically by necrotizing vasculitis. To study the clinical and histologic features of urticarial vasculitis in patients seen in the dermatology department of Hospital Universitario Virgen de Rocío in Seville, Spain, and to examine the association between hypocomplementemia and systemic disease. We performed a chart review of histologically confirmed cases of urticarial vasculitis in the database of our department covering a period of 10 years. Fifteen patients (9 women and 6 men with a median age of 51 years) were included. In 14 patients (93%), the lesions persisted for more than 24hours, and in 9 cases (60%) the lesions resolved leaving residual purpura or hyperpigmentation. Seven patients (47%) had low complement levels in the blood, 12 (80%) had extracutaneous symptoms, and 8 (53%) had associated systemic disease, the most common of which was systemic lupus erythematosus. Urticarial vasculitis may be underdiagnosed. Response to treatment is variable, and hypocomplementemia and extracutaneous symptoms may indicate the presence of associated systemic disease.

Analysis was carried out to find the correlation between fetal gender and different pregnancy outcomes. A male fetus was associated with an increased incidence of gestational diabetes mellitus (odds risk 1.4), preterm delivery (6.7% for males, 5.5% for females, odds risk 1.24), cesarean section (23.9% for males, 20% for females, odds risk 1.25), and instrumental vaginal delivery (4.4% for males, 3.1% for females, odds risk 1.48), p<0.005. Preeclampsia was more frequent among preterm females and postterm males, p<0.005. It was also more frequent in male-bearing primigravids, p<0.01. We confirm the existence of an adverse effect of a male fetus on pregnancy and labor in our population. We recommend further research to understand the mechanisms and clinical implications of this phenomenon.

    Full Text Available Background. Central venous catheter (CVC related infection is associated with significant increases in morbidity, mortality, and health care cost.This local surveillance study was carry out to monitor the frequency of occurrence of CVC-related blood stream infections. Materials and methods. During the period January – December 2005, 226 CVC specimens were analyzed (quantitative method and microrganism identification from positive samples was performed by Vitek II. In 53 patients it was possible to compare quantitative results with those obtained from blood cultures. Results. Positive CVC samples were 125 (55% and 130 microrganisms were isolated: 109 Gram-positives (84%, 4 Gram-negatives (3%, and 17 mycetes (13%. Among pathogens collected simultaneously from CVC and blood samples, the most frequently isolated were Staphylococcus spp. (30% coagulase-negative staphylococci and 20%. S. aureus and Candida spp. (45%. In the group of patients that presented positive CVC and negative blood samples the most frequently recovered microrganisms were staphylococci. Many isolates (33% were polymicrobial. Conclusions. Catheter-related infections occurred in those patients who presented the same pathogen in both CVC and blood cultures. These infections were principally caused by staphylococci and Candida spp. On the contrary, a possible CVC contamination could be suspected when positive CVC and negative blood cultures were found.

    Montreal is Canada's second-largest city, where mean annual tuberculosis (TB) incidence from 1996 to 2007 was 8.9/100,000. The objectives of this study were to describe the epidemiology of TB among homeless persons in Montreal and assess patterns of transmission and sharing of key locations. We reviewed demographic, clinical, and microbiologic data for all active TB cases reported in Montreal from 1996 to 2007 and identified persons who were homeless in the year prior to TB diagnosis. We genotyped all available Mycobacterium tuberculosis isolates by IS6110 restriction fragment length polymorphism (IS6110-RFLP) and spoligotyping, and used a geographic information system to identify potential locations for transmission between persons with matching isolates. There were 20 cases of TB in homeless persons, out of 1823 total reported from 1996-2007. 17/20 were Canadian-born, including 5 Aboriginals. Homeless persons were more likely than non-homeless persons to have pulmonary TB (20/20), smear-positive disease (17/20, odds ratio (OR) = 5.7, 95% confidence interval (CI): 1.7-20), HIV co-infection (12/20, OR = 14, 95%CI: 4.8-40), and a history of substance use. The median duration from symptom onset to diagnosis was 61 days for homeless persons vs. 28 days for non-homeless persons (P = 0.022). Eleven homeless persons with TB belonged to genotype-defined clusters (OR = 5.4, 95%CI: 2.2-13), and ten potential locations for transmission were identified, including health care facilities, homeless shelters/drop-in centres, and an Aboriginal community centre. TB cases among homeless persons in Montreal raise concerns about delayed diagnosis and ongoing local transmission.

    Stillbirth rates have decreased radically over the last decades. One reason for this is improved perinatal care. The aim of this study was to explore whether sub-optimal factors in stillbirths were more frequent among non-western than western women. Population-based perinatal audit of 356 stillbirths after gestational week 23, in 2 Norwegian counties during 1998-2003 (4.2 per 1,000 deliveries); of these 31% were born to non-western women. By audit, the stillbirths were attributed to optimal or sub-optimal care factors. Multivariate methods were used to analyse the data. Sub-optimal factors were identified in 37% of the deaths. When compared to western women, non-western women had an increased risk of stillbirth (OR: 2.2; 95% CI: 1.3-3.8), and an increased risk of sub-optimal care (OR: 2.4; 95% CI: 1.5-3.9). More often, non-western women received sub-optimal obstetric care (plabour progression. A common failure in antenatal care for both groups was unidentified or inadequate management of intrauterine growth restriction or decreased fetal movements. Non-western women were less prone to attend the program for antenatal care or to take the consequences of recommendations from health professionals. Inadequate communication was documented in 47% of non-western mothers; an interpreter was used in 29% of these cases. Non-western women constituted a risk group for sub-optimal care factors in stillbirths. Possibilities for improvements include a reduction of language barriers, better identification and management of growth restriction for both origin groups, and adequate intervention in complicated vaginal births; with increased vigilance towards non-western women.

    To describe the demographics, clinical characteristics and microbiologic findings of infant (≤2 years old) tuberculosis (TB) in a high TB burden country. Between Feb, 2007 and Jun, 2015, 115 TB infants who admitted to our hospital were enrolled in the study. Their clinicopathological characteristics were reviewed and analyzed. The mean age was 10.1 ± 7.4 (SD) months, and 84 of 115 infants (73.0 %) were males. 23 patients (20.0 %) had isolated pulmonary TB, 18 patients (15.7 %) had pulmonary and extrapulmonary TB (EPTB), the remaining 74 patients (64.4 %) had exclusively EPTB. The most common site of EPTB was lymph node (n = 61), 54 cases were left axillary lymph node involvement. 49 of 51 patients (96.1 %) were validated by pathological examination, 5 of 57 patients (8.8 %) were positive on acid fast bacilli smear, and 27 of 103 patients (26.2 %) were confirmed by mycobacterial culture. 29 of 59 patients (49.2 %) were PPD positive, 14 of 30 patients (46.7 %) were T-SPOT.TB positive. The most common complaints of patients were lymph node swelling (53.0 %), fever (36.5 %), cough (28.7 %) and dyspnea (10.4 %). There was significant difference in the time before hospital admission among different types of tuberculosis (P EPTB was more common than pulmonary TB, tuberculous lymphadenitis constituted a high proportion of EPTB; there appears to be an association between the incidence of axillary lymph node TB and BCG vaccination among infants in China.

    The Troubles in Northern Ireland have now lasted 34 years. Divisions and strife between the opposing loyalist and republican communities, and between the communities and the security forces, have led to thousands of deaths and injuries. The violence has often been indiscriminate injuring and killing totally innocent people. Staff at the Regional Disablement Services at Musgrave Park Hospital, Belfast have had the responsibility for helping to rehabilitate those who have suffered limb loss, both civilians and security forces personnel. In this study the authors present patient demographics for those survivors, referred for prosthetic fitting, who have sustained limb amputations as a result of the Troubles from 1969 to 2003, with the cause of injury, resulting levels of amputation, associated injuries, time to first prosthetic fitting and reason for any delay in fitting identified. One hundred and twenty-nine (129) patients sustained amputations, 110 male and 19 female with an age range at the time of injury from 7 to 60 years. Seventy-two (72) were civilian. Ninety-three (93) underwent immediate amputation, the most frequent level of amputation being trans-femoral. Delayed healing of deep wounds was the most common reason for delayed amputation; other causes were chronic osteomyelitis, malunited fractures and failed arthrodesis, often associated with chronic pain. Ninety-two (92) patients required amputation of one limb or part thereof, 35 required amputation of 2 limbs and 2 underwent triple amputation. Three (3) patients lost both hands. Sixty seven percent (67%) had other associated physical injuries. Thirty-two (32) patients had a delay of 6 months or more in fitting a prosthesis. The most common cause of injury was the car bomb.

  12. Raman studies of oxide minerals: a retrospective on cristobalite phases

    A brief review of early Raman studies of oxide minerals is given, emphasizing aspects yet to receive modelling. To these are added extensive unpublished infrared data on {alpha}- and {beta}-cristobalite SiO{sub 2} and AlPO{sub 4}, following a soft mode and its damping from 132 cm{sup -1} at 20 K to about 80 cm{sup -1} just below the AlPO{sub 4} {alpha}-{beta} transition temperature and from 155 to 125 cm{sup -1} in SiO{sub 2} (the transitions are of first order). Rather good data exist on the {alpha}- and {beta}-cristobalite phases of AlPO{sub 4} and BPO{sub 4} single crystals (not powders) which are discussed in terms of the more recent controversy regarding {beta}-cristobalite SiO{sub 2}. The {alpha}-{beta} cristobalite phase transition in AlPO{sub 4} doubles the primitive cell size on cooling, with a probable D{sub 2d} to D{sub 2} point group symmetry reduction: {beta}-AlPO{sub 4} is likely to be I4-bar 2d (D{sub 2d}{sup 12}) with Z = 1 formula group, and {alpha}-AlPO{sub 4} to be C 222{sub 1} (D{sub 2}{sup 5}). For AlPO{sub 4} our results favour the model of Liu et al (1993 Phys. Rev. Lett. 70 2750) over that of Swainson and Dove (1993 Phys. Rev. Lett. 71 3610). The point group symmetries appear to be the same in cristobalite SiO{sub 2}, so that the previously proposed tetragonal space group symmetry D{sub 4}{sup 4} (P4{sub 1}2{sub 1}2) for {alpha}-SiO{sub 2} and the O{sub h}{sup 7} (Fd3m) phase for {beta}-SiO{sub 2} are only slow time averages that do not control selection rules or electronic band structures.

    To identify and synthesize the national and international literature on forensic nursing in Brazil. Forensic nursing is a new specialty to the nursing practice in Brazil, being recognized by the Federal Nursing Council of Brazil in 2011. In 2016, the first forensic nursing specialization programme was authorized in the country. The implementation of forensic nursing specialty in Brazil marks new possibilities for the nursing practice, making it possible for nurses to develop additional skills to intervene in various situations under the Brazilian Unified Healthcare System. A systematic search of the literature was conducted using the keyword 'Forensic nursing' in combination with 'Brazil'. LILACS, MEDLINE, EMBASE, Scopus and Web of Science databases were searched. Studies were also retrieved from the grey literature. Once literature had been identified, a thematic analysis was undertaken in order to extract themes, which were: establishment of the forensic nursing specialty and its contributions to Brazil and its practical implications. Eight manuscripts and 20 studies from the grey literature were included in the final review. Most studies (54%) were literature reviews that indicated forensic nursing as an emerging specialty in Brazil, addressing educational, instructional, communicative or contextual aspects of the specialty in the country. In the nursing profession in Brazil, few studies exist on forensic nursing and those are limited to short communications. Although most studies address the definition of forensic nursing, others present its implications in various situations such as intimate partner violence, domestic violence, sexual abuse and elder mistreatment. Despite the study limitations, it provides evidence that forensic nursing has been silently implemented in the country with the need for more evidence-based studies to support its constitution as a specialty in Brazil. © 2016 International Council of Nurses.

    This study reports the antimicrobial evaluation of the species most commonly used in Rio Grande do Sul (RS), the southernmost state of Brazil, for treating conditions likely to be associated with microorganisms. A four-stage process of documentation and evaluation was conducted: (a). review of RS ethnobotanical studies; (b). analysis of traditional uses; (c). literature survey on phytochemical and pharmacological data; (d). microbiological screening of selected plants. From the 149 species initially identified, 49 were cited as being used for microbial associated conditions in at least two other regions in RS, and 18 were further selected for screening. The crude methanol extract of these 18 plants were evaluated against seven microorganisms using the diffusion agar test. Extracts from Chaptalia nutans, Cordia monosperma, Echinodorus grandiflorus, Eugenia uniflora, Leonurus sibiricus, Luehea divaricata, Malva sylvestris, Ocotea odorifera, Parapiptadenia rigida, Pluchea sagittalis, Psidium cattleyanum and Senna neglecta were active against at least one microorganism. Although preliminary, these results are useful for rationalizing the use of medicinal plants in established systems of traditional medicine in primary health care.

    Full Text Available Two hundred and thirty paraffin-embedded biopsies obtained from female cervical lesions were tested for the presence of human papillomavirus (HPV types 6/11,16/18 and 31/33/35 DNA using non-isotopic in situ hybridization. Specimens were classified according to the Bethesda System in low grade squamous intraepithelial lesion (LSIL, high grade SIL (HSIL and squamous cell carcinoma (SCC. HPV prevalence ranged from 92.5% in LSIL to 68.5% in SCC. Benign types were prevalent in LSILs while oncogenic types infected predominantly HSILs and SCC. HPV infection showed to be age-dependent, but no significant relation to race has been detected. Patients were analyzed through a five-year period: 20.7% of the lesions spontaneously regressed while 48.9% persisted and 30.4% progressed to carcinoma. Patients submitted to treatment showed a 19.4% recurrence rate. High risk types were present in 78.6% (CrudeOR 13.8, P=0.0003 of the progressive lesions, and in 73.7% of the recurrent SILs (COR 19.3, P=0.0000001. Possible co-factors have also been evaluated: history of other sexually transmitted diseases showed to be positively related either to progression (Adjusted OR 13.0, P=0.0002 or to recurrence (AOR 17.2, P=0.0002 while oral contraceptive use and tobacco smoking were not significantly related to them (P>0.1. Association of two or more co-factors also proved to be related to both progression and recurrence, indicating that they may interact with HPV infection in order to increase the risk of developing malignant lesions.

    The objective was to evaluate correlations between suicide, homicide and socio-demographic variables by an ecological study. Mortality and socio-demographic data were collected from official records of the Ministry of Health and IBGE (2010), aggregated by state (27). The data were analyzed using correlation techniques, factor analysis, principal component analysis with a varimax rotation and multiple linear regression. Suicide age-adjusted rates for the total population, men and women were 5.0, 8.0, and 2.2 per 100,000 inhabitants respectively. The suicide rates ranged from 2.7 in Pará to 9.1 in Rio Grande do Sul. Homicide for the total population, men and women were 27.2, 50.8, and 4.5 per 100,000, respectively. The homicide rates ranged from 13.0 in Santa Catarina to 68.9 in Alagoas. Suicide and homicide were negatively associated, the significance persisted among men. Unemployment was negatively correlated with suicide and positively with homicide. Different socio-demographic variables were found to correlate with suicide and homicide in the regressions. Suicide showed a pattern suggesting that, in Brazil, it is related to high socioeconomic status. Homicide seemed to follow the pattern found in other countries, associated with lower social and economic status.

    2017-07-01

    OBJECTIVE The authors conducted a study to compare neurological deficit rates associated with complex adult spinal deformity (ASD) surgery when recorded in retrospective and prospective studies. Retrospective studies may underreport neurological deficits due to selection, detection, and recall biases. Prospective studies are expensive and more difficult to perform, but they likely provide more accurate estimates of new neurological deficit rates. METHODS New neurological deficits were recorded in a prospective study of complex ASD surgeries (pSR1) with a defined outcomes measure (decrement in American Spinal Injury Association lower-extremity motor score) for neurological deficits. Using identical inclusion criteria and a subset of participating surgeons, a retrospective study was created (rSR1) and neurological deficit rates were collected. Continuous variables were compared with the Student t-test, with correction for multiple comparisons. Neurological deficit rates were compared using the Mantel-Haenszel method for standardized risks. Statistical significance for the primary outcome measure was p spinal deformities, and exclusion criteria were identical. Sagittal Cobb measurements were higher in pSR1, although sagittal alignment was similar. Preoperative neurological deficit rates were similar in the groups. Three-column osteotomies were more common in pSR1, particularly vertebral column resection. New neurological deficits were more common in pSR1 (pSR1 17.3% [95% CI 12.6-22.2] and rSR1 9.0% [95% CI 5.0-13.0]; p = 0.01). The majority of deficits in both studies were at the nerve root level, and the distribution of level of injury was similar. CONCLUSIONS New neurological deficit rates were nearly twice as high in the prospective study than the retrospective study with identical inclusion criteria. These findings validate concerns regarding retrospective cohort studies and confirm the need for and value of carefully designed prospective, observational cohort

    Full Text Available Introduction: The nonsyndromic orofacial cleft is the fourth most common birth defect, but in Brazil, data about the cleft epidemiology are not accurate. Objective: This study aimed to describe the epidemiologic characteristics of oral cleft cases at Specialized Society Attending Cleft Patient in Sergipe State. Methods: Data were obtained from patients' medical records in relation to the following characteristics: age; gender; race; origin; cleft type; additional malformations and/or complications; prenatal accomplishment; treatment applied. For diagnosis analysis, it was noted if mothers had received prenatal care and if they had ultrasonography performed and if the cleft was viewed in it. Results: We observed a prevalence of male gender (54%. Age between 0 and 4 years old was most prevalent (53%, and pheoderma race was observed in 47%. Transincisive foramen cleft was found in 52.3% of the individuals. The prevalence of pre- and transincisive foramen cleft was higher in men (66.3 and 55.7%, women accounted for 65.0% of postincisive foramen, and atypical facial cleft (0.3% occurred in one case. Associated malformations and complications were present in 12% of patients. Prenatal care was reported by 48% of the mothers. Conclusion: In this study male gender was the most affected, and 0 to 4 years was the most frequent age group. Transincisive foramen cleft type was most frequently encountered. Prenatal care was reported by most mothers. So, this study found that early treatment is a reality in SEAFESE (Service Specializing in Cleft Care of Sergipe, and consequently the chances of successful integration of the child to society will be better.

  17. Marine zooplankton studies in Brazil: a brief evaluation and perspectives

    Directory of Open Access Journals (Sweden)

    Rubens M. Lopes

    2007-09-01

    Full Text Available Marine zooplankton research in Brazil has been primarily descriptive, with most studies focusing on community structure analysis and related issues. The composition and spatial distribution of several taxonomic groups are currently well known, although less-abundant and small-sized taxa as well as initial stages of almost all species have received little attention. Some numerically important taxa such as heterotrophic protists, ctenophores, acoel turbellarians and ostracods remain virtually unstudied. Large sectors of the continental shelf have not been sampled in detail, particularly those areas influenced by the North Brazil Current (5ºN-15ºS. Zooplankton abundance and biomass in offshore waters have seldom been quantified, and information on the distribution and vertical migration of meso- and bathypelagic species are lacking. Additional faunistic assessments must target those less-studied taxa and geographical locations. However, priority in ecological studies should be given to process-oriented investigations aimed at understanding the mechanisms controlling zooplankton distribution, trophic interactions within pelagic food webs and production cycles in relation to the physical environment. An effort should be made to incorporate state-of-the-art sampling technology and analytical methods into future research projects.As pesquisas sobre o zooplâncton marinho no Brasil têm sido primariamente descritivas, com a maioria dos estudos enfocando a análise da estrutura da comunidade e assuntos relacionados. A composição e a distribuição espacial de muitos grupos taxonômicos encontram-se bem estudadas, embora os táxons menos abundantes e de menores dimensões, assimcomo os estágios iniciais do ciclo de vida da maioria das espécies, tenham recebido pouca atenção. Alguns táxons numericamenteimportantes encontram-se pouco estudados, como no caso dos protistas heterotróficos, ctenóforos, turbelários acelos e ostrácodes. Amplos

  1. An ecological approach to prospective and retrospective timing of long durations: a study involving gamers.

    Science.gov (United States)

    Tobin, Simon; Bisson, Nicolas; Grondin, Simon

    2010-02-17

    To date, most studies comparing prospective and retrospective timing have failed to use long durations and tasks with a certain degree of ecological validity. The present study assessed the effect of the timing paradigm on playing video games in a "naturalistic environment" (gaming centers). In addition, as it involved gamers, it provided an opportunity to examine the effect of gaming profile on time estimation. A total of 116 participants were asked to estimate prospectively or retrospectively a video game session lasting 12, 35 or 58 minutes. The results indicate that time is perceived as longer in the prospective paradigm than in the retrospective one, although the variability of estimates is the same. Moreover, the 12-minute session was perceived as longer, proportionally, than the 35- and 58-minute sessions. The study also revealed that the number of hours participants spent playing video games per week was a significant predictor of time estimates. To account for the main findings, the differences between prospective and retrospective timing are discussed in quantitative terms using a proposed theoretical framework, which states that both paradigms use the same cognitive processes, but in different proportions. Finally, the hypothesis that gamers play more because they underestimate time is also discussed.

    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.

    Full Text Available Invasive infections caused by Candida spp. are an important problem in immunocompromised patients. There is scarce data on the epidemiology of blood stream candidiasis in Salvador, Brazil. This study evaluates the risk factors associated with candidemia, among patients admitted to three tertiary, private hospitals, in Salvador, Brazil. We conducted a case-control, retrospective study to compare patients with diagnosis of candidemia in three different tertiary hospitals in Salvador, Brazil. Patients were matched for nosocomial, acquired infections, according to the causal agent: cases were defined by positive blood cultures for Candida species. Controls were those patients who had a diagnosis of systemic bacterial infection, with a positive blood culture to any bacteria, within the same time period (± 30 days of case identification. The groups were compared for the main known risk factors for candidemia and for mortality rates. A hundred thirty-eight patients were identified. Among the 69 cases, only 14 were diagnosed as infected by Candida albicans. Candida species were defined in only eight cultures: C. tropicalis (4 cases, C. glabrata, C. parapsilosis, C. guillermondi, C. formata (1 case each. The main risk factors, identified in a univariate analysis, were: presence of a central venous catheter (CVC, use of parenteral nutrition support (PNS, previous exposure to antibiotics, and chronic renal failure (CRF. No association was detected with surgical procedures, diabetes mellitus, neutropenia or malignancies. Patients were more likely to die during the hospitalization period, but the rates of death caused by the infections were similar for cases and controls. The length of hospitalization was similar for both groups, as well as the time for a positive blood culture. Blood stream infection by Candida spp. is associated with CVC, PNS, previous use of antibiotics, and CRF. The higher mortality rate for cases probably better reflects the severity

  15. Quality and customer satisfaction: A case study in Brazil

    Science.gov (United States)

    Barcellos, Paulo Fernando Pinto

    The dissertation deals with the case of CEEE-Companhia Estadual de Energia Eletrica, an electric power utility located in Rio Grande do Sul, the southernmost state of Brazil. Customer satisfaction with the services provided by CEEE is investigated within three groups of consumers: residential, commercial, and industrial. The purpose of the dissertation is to find answers to the following research questions: (1) What is service quality in public utilities, and particularly in an electric power company? (2) What service quality dimensions do customers want to be provided and favor the most? (3) How does the market measure service quality? (4) What should be done by companies, and particularly by an electric utility monopoly, to increase the performance of the rendered service? (5) How does this impact customer satisfaction, retention, and intention to recommend? and (6) How do we start a company-wide quality program provided that the resources are scarce and therefore priorities should be set forth? To investigate the posed questions, the study begins with an exploratory survey of CEEE's Board. The survey is followed by qualitative research of the three customer groups. After qualitative analysis of the data is concluded, questionnaires for the quantitative research, as well as hypothetical models, are developed. Dillman's "Total Design Method" is used to design the questionnaires. The basic ACSI (American Customer Satisfaction Model) is used to approach customer satisfaction. Data are processed by PLS (Partial Least Squares) which follows the procedure developed at the National Quality Research Center of the University of Michigan Business School. In summary, commercial customers are the most dissatisfied with the services provided by CEEE, while residential customers are the most satisfied. To improve quality, priority should be placed on commercial customers and include efforts to improve productivity gains throughout the company. Also, CEEE's image should be

    X-linked adrenoleukodystrophy (X-ALD) is a peroxisomal metabolic disorder. Male patients develop adrenocortical insufficiency (80 % before 18 years), a chronic myelopathy (adrenomyeloneuropathy (AMN); all in adulthood), or progressive cerebral demyelination (cerebral ALD; 40 % before 18 years). Cerebral ALD is treated with haematopoetic cell transplantation (HCT). It is unknown if AMN still develops in patients with X-ALD that underwent HCT for cerebral ALD in childhood. A retrospective observational study was performed by selecting all adult patients with X-ALD in our cohort that underwent HCT in childhood. This retrospective study found that three out of five patients in our cohort who underwent HCT in childhood developed signs of myelopathy in adulthood. These data suggest that HCT for cerebral ALD in childhood does not prevent the onset of AMN in X-ALD in adulthood.

  17. Trade Policy and Health: Adding Retrospective Studies to the Research Agenda

    Science.gov (United States)

    Blouin, Chantal

    2017-01-01

    Prospective studies of the potential health consequences of trade and investment treaties, such as the Trans-Pacific Partnership, are critical. These studies can make visible to trade policy-makers the potential negative impacts associated to such treaties and can influence the outcomes of such negotiations. However, few researchers have examined retrospectively the consequences of trade agreements. With more than 400 trade agreements and more than 2000 investment treaties currently in force, researchers have a large corpus of agreements to analyse in order to assess not only their potential impacts on health system and population health, but also their actual impacts. This comment suggests some research questions that would benefit from retrospective inquiry. PMID:28812809

    This study provides a retrospective review from the forensic files of the University Centre of Legal Medicine in Western Switzerland in Geneva, from January 1956 to December 2005. The studied homicide-suicide cases cover a period of half a century (50 years). As a rule, all police-ordered forensic examinations of violent death cases in the Canton of Geneva are conducted by the University Centre of Legal Medicine. All of the data necessary for an exhaustive retrospective study are thus readily available. During the period covered in this work, 228 homicides were perpetrated in Geneva. In 23 cases, the homicide was followed by the suicide of the aggressor. The 34 victims of these homicides (18 women, 1 man and 15 children) had either an intimate or filial relationship with the perpetrator. Most of the suicidal perpetrators were men that killed their spouses or intimate partners, with children as additional victims in some cases. Shooting was the most common means to kill, followed by stabbing. The majority of the victims and perpetrators were Swiss nationals. This retrospective study shows that in the last 50 years, homicide-suicide cases in the Canton of Geneva have been a rare and an episodic phenomena with a very variable frequency from 1 year to another.

    Full Text Available Introduction: The chronic kidney disease outcomes and practice patterns study (CKDopps is an international observational, prospective, cohort study involving patients with chronic kidney disease (CKD stages 3-5 [estimated glomerular filtration rate (eGFR < 60 ml/min/1.73 m2, with a major focus upon care during the advanced CKD period (eGFR < 30 ml/min/1.73 m2]. During a 1-year enrollment period, each one of the 22 selected clinics will enroll up to 60 advanced CKD patients (eGFR < 30 ml/min/1.73 m2 and not dialysis-dependent and 20 earlier stage CKD patients (eGFR between 30-59 ml/min/1.73 m2. Exclusion criteria: age < 18 years old, patients on chronic dialysis or prior kidney transplant. The study timeline include up to one year for enrollment of patients at each clinic starting in the end of 2013, followed by up to 2-3 years of patient follow-up with collection of detailed longitudinal patient-level data, annual clinic practice-level surveys, and patient surveys. Analyses will apply regression models to evaluate the contribution of patient-level and clinic practice-level factors to study outcomes, and utilize instrumental variable-type techniques when appropriate. Conclusion: Launching in 2013, CKDopps Brazil will study advanced CKD care in a random selection of nephrology clinics across Brazil to gain understanding of variation in care across the country, and as part of a multinational study to identify optimal treatment practices to slow kidney disease progression and improve outcomes during the transition period to end-stage kidney disease.

    Ninety percent of the lesions resulting from diving injuries affect the cervical spine and are potentially associated with spinal cord injuries. The objective is to determine the most frequent lesion mechanisms. Evaluate the therapeutic alternatives and the biomechanical evolution (kyphotic deformation) of diving-induced cervical spine injuries. Define epidemiological characteristics of diving injuries. A retrospective analysis over a period of 10 years was undertaken for patients admitted to the Department of Neurosurgery of Montpellier, France, with cervical spinal injuries due to a diving accident. Patients were re-evaluated and clinical and radiological evaluation follow-ups were done. This study included 64 patients. Cervical spine injuries resulting from diving predominantly affect young male subjects. They represent 9.5% of all the cervical spine injuries. In 22% of cases, patients presented severe neurological troubles (ASIA A, B, C) at the time of admission. A surgical treatment was done in 85% of cases, mostly using an anterior cervical approach. This is a retrospective study (type IV) with some limitations. The incidence of diving injuries in our region is one of the highest as compared to reports in the literature. Despite an increase of our surgical indications, 55% of these cases end up with a residual kyphotic deformation but there is no relationship between the severity of late vertebral deformity and high Neck Pain and Disability Scale (NPDS) scores.

The aim of the present study was to investigate the incidence, treatment, and complication of patients with ameloblastoma in East-Indonesia during six years retrospective study. This retrospective study included 84 patients who were diagnosed with ameloblastoma from 2011 to 2016. There were 56 patients with treatment data available. Data from each patient, including gender, age, histologic type, the size of the tumor, radiologic form, tumor location, type of treatment, and complication were reviewed and analyzed retrospectively. Fourteen patients were diagnosed with unicystic ameloblastoma (25%), thirty two patients with multicystic follicular ameloblastoma (57%) and ten patients with an unspecified multicystic ameloblastoma (18%). A total of about 35 patients were treated conservatively (62.5%) and 21 patients were treated radically (37.5%). Swelling was present as a pre-operative complication in all 56 cases (100%). There were no complaints concerning speech. The majority findings of the histologic type were multicystic ameloblastoma and their location were in the mandible. Most ameloblastoma were treated conservatively and reconstructions were made with only titanium plates and not bone graft.

    We compared the results of prospective and retrospective cohort studies in the field of digestive surgery to clarify whether the results of prospective cohort studies were more similar to those of randomized controlled trials (RCTs). We conducted a secondary analysis of the results to compare the results of RCTs with those of cohort studies in meta-analyses of 18 digestive surgical topics. The data from the prospective and retrospective cohort studies were combined. The summary estimates of each design were compared with those of RCTs. We used the Z score to investigate discrepancies. Twenty-nine outcomes of 11 topics were investigated in 289 cohort studies (prospective, n = 69; retrospective, n = 220). These were compared with the outcomes of 123 RCTs. In comparison to retrospective studies, the summary estimates of the prospective cohort studies were more similar to those of the RCTs [19/29 (prospective) vs. 10/29 (retrospective), P = 0.035). Five of the 29 outcomes of prospective studies and 6 of 29 outcomes of retrospective studies (P = 0.99) showed significant discrepancies in comparison to RCTs. In the digestive surgical field, the results of prospective cohort studies tended to be more similar to those of RCTs than retrospective studies; however, there were no significant discrepancies between the two types of cohort study.

    Prognostic models reflect the population characteristics of the countries from which they originate. Predictive models should be customized to fit the general population where they will be used. The aim here was to perform external validation on two predictive models and compare their performance in a mixed population of critically ill patients in Brazil. Retrospective study in a Brazilian general intensive care unit (ICU). This was a retrospective review of all patients admitted to a 41-bed mixed ICU from August 2011 to September 2012. Calibration (assessed using the Hosmer-Lemeshow goodness-of-fit test) and discrimination (assessed using area under the curve) of APACHE II and SAPS III were compared. The standardized mortality ratio (SMR) was calculated by dividing the number of observed deaths by the number of expected deaths. A total of 3,333 ICU patients were enrolled. The Hosmer-Lemeshow goodness-of-fit test showed good calibration for all models in relation to hospital mortality. For in-hospital mortality there was a worse fit for APACHE II in clinical patients. Discrimination was better for SAPS III for in-ICU and in-hospital mortality (P = 0.042). The SMRs for the whole population were 0.27 (confidence interval [CI]: 0.23 - 0.33) for APACHE II and 0.28 (CI: 0.22 - 0.36) for SAPS III. In this group of critically ill patients, SAPS III was a better prognostic score, with higher discrimination and calibration power.

    2017-11-01

    Residual bacterial biofilm and/or bacteria in planktonic form may be survived in the bone following an extraction of an infected tooth that was endodontically treated unsuccessfully Failed endodontic treatment may be associated with failure of implants to osseointegrate in the same sites. Therefore, the aim of this retrospective case-control study is to examine the risk of implant failure in previous failed endodontic sites. This retrospective case-control study is based on 94 dental records of implants placed at the University of Minnesota School of Dentistry. Dental records of patients who received an implant in sites with previously failed endodontic therapy in the dental school were identified from the electronic database, while control subjects were obtained from the same pool of patients with the requirement to have received an implant in a site that was not endodontically treated. The mean age of the population was 62.89±14.17 years with 57.4% of the sample being females and 42.6% of them being males. In regards to the socio-economic status and dental insurance, 84.0% of this population was classified as low socio-economic status and 68.1% had dental insurance. Tobacco use was self-reported by 9.6% and hypercholesterolemia was the most prevalent systemic medical condition. Dental implant failure was identified in two of the included records (2.1%), both of which were placed in sites with a history of failed endodontic treatment. Within the limitations of this retrospective case-control study, further investigation with a larger population group into implant failure of sites that previously had unsuccessful endodontic treatment would be warranted. Implant failure may be associated with a history of failed endodontic treatment. Key words:Implantology, endodontics, osseointegration, treatment outcome, case-control study.

    Full Text Available Abstract Background The etiology of multifactorial human diseases involves complex interactions between numerous environmental factors and alleles of many genes. Efficient statistical tools are demanded in identifying the genetic and environmental variants that affect the risk of disease development. This paper introduces a retrospective polytomous logistic regression model to measure both the main and interaction effects in genetic association studies of human discrete and continuous complex traits. In this model, combinations of genotypes at two interacting loci or of environmental exposure and genotypes at one locus are treated as nominal outcomes of which the proportions are modeled as a function of the disease trait assigning both main and interaction effects and with no assumption of normality in the trait distribution. Performance of our method in detecting interaction effect is compared with that of the case-only model. Results Results from our simulation study indicate that our retrospective model exhibits high power in capturing even relatively small effect with reasonable sample sizes. Application of our method to data from an association study on the catalase -262C/T promoter polymorphism and aging phenotypes detected significant main and interaction effects for age-group and allele T on individual's cognitive functioning and produced consistent results in estimating the interaction effect as compared with the popular case-only model. Conclusion The retrospective polytomous logistic regression model can be used as a convenient tool for assessing both main and interaction effects in genetic association studies of human multifactorial diseases involving genetic and non-genetic factors as well as categorical or continuous traits.

    To define a general methodology for maximising the success of follow-up processes for retrospective cohort studies in New Zealand, and to illustrate an approach to developing country-specific follow-up methodologies. We recently conducted a cohort study of mortality and cancer incidence in New Zealand professional fire fighters. A number of methods were used to trace vital status, including matching with records of the New Zealand Health Information Service (NZHIS), pension records of Work and Income New Zealand (WINZ), and electronic electoral rolls. Non-electronic methods included use of paper electoral rolls and the records of the Registrar of Births Deaths and Marriages. 95% of the theoretical person-years of follow-up of the cohort were traced using these methods. In terms of numbers of cohort members traced to end of follow-up, the most useful tracing methods were fire fighter employment records, the NZHIS, WINZ, and the electronic electoral rolls. The follow-up process used for the cohort study was highly successful. On the basis of this experience, we propose a generic, but flexible, model for follow-up of retrospective cohort studies in New Zealand. Similar models could be constructed for other countries. Successful follow-up of cohort studies is possible in New Zealand using established methods. This should encourage the use of cohort studies for the investigation of epidemiological issues. Similar models for follow-up processes could be constructed for other countries.

    Noradrenaline (NA) can be infused through various systems including single or double syringe pumps. The aim of this study was to define the best and most efficient infusion system in an emergency context. This was a retrospective clinical study based on the analysis of patients' hemodynamic data. Three infusion lines used presently in our postoperative ICU were compared through a retrospective clinical study: an NA syringe pump at 2mL/h and a saline carrier solution syringe pump at 8mL/h (infusion system 1- IS1) or 5mL/h (IS2), both connected to a very low dead-space volume set (V=0.046mL); IS3 with the same NA syringe at 2mL/h directly connected to the central venous catheter. Mean arterial pressure (MAP) was obtained from retrospective data analysis of ICU patients with postoperative septic shock criteria. Infusion systems were compared according to the time required to reach an MAP greater than 65mmHg after the onset of infusion. Data from 37 patients was analysed. The MAP objective was attained in 14:00 minutes (9:20 - 26:10, n=15) with IS1, in 19:10 minutes (12:20 - 27:20, n=13) with IS2 and in 34:10 minutes (23:10 - 62:30, n=9) with IS3 (P=0.00032). The use of a double syringe pump system associated with a very low dead-space volume infusion set appears to be the most appropriate system for NA infusion.

    2015-01-01

    The aim of the present clinical retrospective study was to evaluate the long-term survival and clinical performance of veneered lithium disilicate single restorations in anterior and posterior areas after up to 11 years. Following a rigid protocol, 275 lithium disilicate single crowns (35 IPS Empress II and 240 e.max Press) were cemented over 11 years, in 106 patients, using an adhesive technique; of these 106 were anterior (38.5%) and 169 posterior (61.5%) teeth. Teeth receiving endodontic therapy and composite reconstruction (50%) and teeth with preexisting metalceramic crowns, called prosthetic retreatments (PR; 65%), were included as well. Of the 106 patients enrolled in the study, 25 (23.5%) were diagnosed with bruxism habits, and 7 of these patients (6.6% of all patients) received full-mouth single lithium disilicate restorations (FMR). The exclusion criteria for this retrospective clinical study were: monolithic lithium disilicate crowns, teeth with cast post and cores, implant-supported all-ceramic crowns, active periodontitis, and/or poor oral hygiene. Clinical reevaluation was performed by the clinicians who prepared and luted them during maintenance appointments between January 2012 and October 2013. Number of restoration failures and characteristics of failures were recorded. Marginal adaptation and marginal discoloration were evaluated based on the Cvar-Ryge criteria. The overall cumulative survival rate was 98.2%. The failures recorded were the result of either mechanical failure or debonding. Five crowns failed mechanically-three because of chipping and two because of core fracture-and were replaced. None of the failed crowns was associated with the bruxers with FMR. A total of 15 crowns debonded (5.5% of all crowns); however, 11 belonged to the same patient who had endodontically treated and reconstructed abutments. In this retrospective clinical evaluation of up to 132 months, veneered lithium disilicate single crowns had a low failure rate.

    Ceramic veneer fracture is a frequent complication in implant-borne fixed restorations. The retrospective clinical study assesses the effect of bruxism on this complication. A sample of 507 implant-borne fixed units inserted between 1995 and 2011 in 144 patients were examined. Any detected veneer fractures were assigned to one of four groups according to extent and position. A hypothetical correlation between bruxism and ceramic veneer fractures was examined. Of 34 patients (23.6%) with at least one ceramic veneer fracture, 24 were bruxers (70%) and 10 were nonbruxers (30%) (P = .002). Bruxism may pose a risk for ceramic fractures.

    Drug-drug interactions (DDIs) are one cause of adverse drug events and can cause harm to hospitalized patients. Little has been done to study the relationship between potential DDIs and an increased length of stay (LOS) in the intensive care unit (ICU). The aim of this study was to determine the frequency of potential DDIs during ICU stays and to determine whether the frequency of these adverse events was associated with ICU LOS. This retrospective cohort study was conducted from January to December 2007 in the ICU of the General Hospital of Vitória da Conquista, Brazil. The study population comprised all patients aged >18 years admitted to the hospital's ICU. Demographic and prescription data were collected from medical files. All prescriptions administered during the period were examined. Potential DDIs were identified and classified according to the book Drug Interaction Facts. The median LOS was determined by the Kaplan-Meier method and Cox proportional hazards models were fitted to analyse the relationship between potential DDIs and the LOS. The study population comprised 236 adults, 158 (67%) of them men, between the ages of 18 and 96 years, with a mean ± SD age of 50 ± 20 years. The median LOS among patients with at least one DDI was 12 days compared with 5 days among those with no DDIs (p < 0.01). Multiple Cox proportional regression analyses showed that a prolonged ICU stay was positively associated with DDIs (hazard ratio [HR] 0.54; 95% CI 0.37, 0.80; p < 0.01), where an HR <1 indicates a variable that increases the risk of prolonged stay (i.e. an adverse outcome). This association was true even after controlling for the cost of hospitalization, the number of procedures and the number of prescribed drugs. In this study, DDIs were found to be associated with a longer ICU stay. Given that LOS is an important indicator of the quality of health care delivered and that DDIs are considered avoidable, specific measures are necessary to

    Primary gastrointestinal (GI) lymphomas (GIL) are uncommon diseases that can involve the whole GI tract. Considerable variation exists in the literature with respect to incidence of the various histological subtypes and sites of involvement. This study was undertaken to establish the anatomic distribution, histological subtypes and sites of GI lymphomas of patients from Western Algeria. The case records of 58 consecutive patients with GIL diagnosed at the Pathologies Departments of Algerian west region (the Military Hospital of Oran city and the Central University Hospital of Sidi Bel Abbes city) from January 2006 to December 2013 were retrospectively evaluated for epidemiology and histopathology report. All lymphomas were reclassified according to the WHO 2008 classification. A total of 58 patients (39 male, 19 female) with mean age of 61 years and a range of 20-89 years were included in this study. Stomach was the most common site involved (70.7%). The commonest histological subtype was mucosa-associated lymphoid tissue (MALT) B cell lymphoma (46.6%), followed by diffuse large B-cell lymphomas (DLBCL) (43.1%).The frequency of Helicobacter pylori (HP) positivity differ between gastric and intestinal location P=0.003 and correlates with the histological type P=0.01. This retrospective study of patients with GI lymphoma from Western Algeria illustrates the pattern of distribution of various common and rare histological subtypes. More studies are necessary to find a potential cause, risk factor or genetic mutation that can explain these specific characteristics of GIL.

    The objective of this study was to describe the results of anatomic pulmonary resections performed by video-assisted thoracoscopy in Brazil. Thoracic surgeons (members of the Brazilian Society of Thoracic Surgery) were invited, via e-mail, to participate in the study. Eighteen surgeons participated in the project by providing us with retrospective databases containing information related to anatomic pulmonary resections performed by video-assisted thoracoscopy. Demographic, surgical, and postoperative data were collected with a standardized instrument, after which they were compiled and analyzed. The surgeons provided data related to a collective total of 786 patients (mean number of resections per surgeon, 43.6). However, 137 patients were excluded because some data were missing. Therefore, the study sample comprised 649 patients. The mean age of the patients was 61.7 years. Of the 649 patients, 295 (45.5%) were male. The majority-521 (89.8%)-had undergone surgery for neoplasia, which was most often classified as stage IA. The median duration of pleural drainage was 3 days, and the median hospital stay was 4 days. Of the 649 procedures evaluated, 598 (91.2%) were lobectomies. Conversion to thoracotomy was necessary in 30 cases (4.6%). Postoperative complications occurred in 124 patients (19.1%), the most common complications being pneumonia, prolonged air leaks, and atelectasis. The 30-day mortality rate was 2.0%, advanced age and diabetes being found to be predictors of mortality. Our analysis of this representative sample of patients undergoing pulmonary resection by video-assisted thoracoscopy in Brazil showed that the procedure is practicable and safe, as well as being comparable to those performed in other countries.

    Sera from the patients (N = 10) with schistosomiasis mansoni of the hospital of Federal University of Pernambuco, the Schistosoma mansoni egg-positive (N = 51) and -negative (N = 452) inhabitants in Cabo City area, out-patients (N = 37) of the IMIP hospital and Japanese immigrants (N = 127) in Petrolina City area of northeast Brazil as well as Japanese healthy subjects (N = 30) were examined by serological tests including an enzyme-linked immunosorbent assay with antigens prepared from eggs (ELISA-egg) and adult worms (ELISA-adult). The ELISA with egg or adult antigen correctly identified 100% of the uninfected individuals lived in non-endemic area of schistosomiasis. Moreover, when examined cross-reactivity of our ELISA with sera isolated from 78 subjects infected with various intestinal parasitic infections, only one of these sera reacted with the egg and adult antigens. On the examination of 51 sera from the egg-positive subjects, the ELISA-egg revealed the highest sensitivity (98.0%), whereas a large number of false negative reactions of ELISA-adult, Ouchterlony method using adult antigen, circumoval precipitation and immediate intradermal skin test were observed. A low sensitivity of these serologic tests except for ELISA-egg appears to be primarily due to their inability to detect antibody in the sera from egg-positive infantiles. There was no positive correlation between the absorbance values of these two types of ELISA among the sera isolated from ELISA-positive subjects. Rather, by the reactivity of these sera to egg or adult antigen, they could be divided into two subgroups; one reacted more positively with egg antigen and the other with adult antigen. Moreover, it was confirmed that the sera from young subjects (under 20 years old) appear to be highly reactive to the egg antigen than did aged ones. These data suggest that the ELISA with egg antigen, but not with the adult antigen, appears to be useful for the serological survey of schistosomiasis mansoni

    The modulation of adenosine receptors has been proposed as new therapeutic target for chronic obstructive pulmonary disease, but studies in humans were negative. Caffeine is widely consumed and acts by non-selective modulation of these receptors, allowing for a non-interventional evaluation of the purinergic effects on COPD. We evaluated the effects of chronic caffeine consumption on the risk for COPD exacerbations. Retrospective study including patients with COPD. The total number of exacerbations during a three-year period and the mean daily caffeine consumption in the last twenty years were evaluated. A univariate and multiple regression analysis were performed for evaluation of the significant predictors of exacerbations. A total of 90 patients were included. Most were males (82.2%) and had a mean forced expiratory volume in the first second (FEV1) of 57.0±17.1% predicted. The mean daily caffeine consumption was 149.7±140.9mg. There was no correlation between the mean caffeine consumption and exacerbations (p>0.05). Our results suggest that caffeine has no significant effect on the frequency of COPD exacerbations. These conclusions are limited by the sample size and the retrospective nature of the study. Copyright © 2015 Sociedade Portuguesa de Pneumologia. Published by Elsevier España, S.L.U.

    The replacement of lost teeth with dental implants is a widespread treatment whose associated problems are also frequently encountered. Nevertheless, the factors associated with early implant failure have not been well documented. Further analyses of the factors influencing osseointegration establishment are required to maximize the predictability of the procedure and minimize implant failures. The purpose of this retrospective clinical study was to explore the association between possible risk factors and early implant failure. This retrospective clinical study evaluated 142 participants who received 276 external connection BTI implants between 2007 and 2011. Participant variables (age, sex, systemic disease, tobacco use, alcohol consumption, bruxism, and degree of periodontal disease), implant variables (type of edentulism, localization, area, diameter, length, and bone quality), intervention variables (expansion mechanisms, sinus augmentation techniques, bone regeneration, and implant insertion), and postoperative variables (presence of pain/inflammation at 1 week postsurgery) were studied. A multilevel logistic regression model (mixed effects-type model) was used to determine the influence of variables on early implant failure. Early implant failure was significantly associated with the male sex (P=.001), severe periodontal disease (P=.005), short implants (P=.001), expansion technique (P=.002), and postoperative pain/inflammation at 1 week postsurgery (Pdental implant failure is more frequent in men and in individuals with severe periodontal disease, short implants, pain/inflammation at 1 week postsurgery, or bone expansion treatment.

    In France, organ donation refusal rates approach 32% of eligible brain deaths. Outright family refusal represents the primary barrier reason for declining organ donation. This retrospective study evaluated factors influencing this decision. A retrospective chart review at Lille Hospital, France, was conducted on brain-death patients eligible for organ donation between 2010 and 2011. Data were collected regarding patient characteristics, death conditions and reasons for refusal based upon family interview. Descriptive statistic analyses were conducted to identify circumstances associated with family refusal. Of 227 eligible organ donors identified, 70 families (30.8%) refused organ donation. The most frequent reason for refusal was desire to keep the body's wholeness (46.3%), followed by religion (16.4%), mistrust of the medical community (13.4%), and revolt against society (6%). The most common causes of death associated with refusal were brutality and suddenness of death (44.8%), early age (23.9%), denial of death (17.9%), and the family culpability (11.9%). In 30% of cases, the family followed the deceased's wishes before his death. Family refusal remains a significant factor associated with the approximately one third of declined eligible organ donations. This retrospective analysis suggested that the most important cause for refusal was a desire to keep the body's wholeness, and the brutality and suddenness of the potential donor's death. Additional research addressing these factors, and their underlying causes, paired with measures to improve professional training and public awareness are warranted to improve organ donation rates.

    ABSTRACT% The cyst in mixed dentition stage cause expansion of buccal cortex, displacement of teeth and may present as case of infection. The cyst in periradicular region of deciduous molar are of frequent occurrence. The differential diagnosis of this lesion is radicular cysts of deciduous molar: developmental or infammatory dentigerous cyst of corresponding unerupted premolar. After going through the available literature of radicular cyst of deciduous molars and dentigerous cysts of developing premolars in mixed dentition we studied the five cases of cyst in periradicular region of deciduous molars in mixed dentition retrospectively for the diagnostic dilemma of radicular cyst verses dentigerous cyst. In conclusion, we can set some criteria for the diagnosis which is particularly important for treatment and for conservation of developing premolar.

    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.

    Polycystic ovary syndrome is characterized by irregular cycles, hyperandrogenism, polycystic ovary at ultrasound and insulin resistance. The effectiveness of D-chiro-inositol (DCI) treatment in improving insulin resistance in PCOS patients has been confirmed in several reports. The objective of this study was to retrospectively analyze the effect of DCI on menstrual cycle regularity in PCOS women. This was a retrospective study of patients with irregular cycles who were treated with DCI. Of all PCOS women admitted to our centre, 47 were treated with DCI and had complete medical charts. The percentage of women reporting regular menstrual cycles significantly increased with increasing duration of DCI treatment (24% and 51.6% at a mean of 6 and 15 months of treatment, respectively). Serum AMH levels and indexes of insulin resistance significantly decreased during the treatment. Low AMH levels, high HOMA index, and the presence of oligomenorrhea at the first visit were the independent predictors of obtaining regular menstrual cycle with DCI. In conclusion, the use of DCI is associated to clinical benefits for many women affected by PCOS including the improvement in insulin resistance and menstrual cycle regularity. Responders to the treatment may be identified on the basis of menstrual irregularity and hormonal or metabolic markers.

    2012-06-01

    Full Text Available Abstract Background The choice of surgical incision is determined by access to the surgical field, particularly when an oncological resection is required. Special consideration is also given to other factors, such as postoperative pain and its sequelae, fewer complications in the early postoperative period and a lower occurrence of incisional hernias. The purpose of this study is to compare the right Kocher’s and the midline incision, for patients undergoing right hemicolectomy, by focusing on short- and longterm results. Methods Between 1995 and 2009, hospital records for 213 patients that had undergone a right hemicolectomy for a right- sided adenocarcinoma were retrospectively studied. 113 patients had been operated via a Kocher’s and 100 via a midline incision. Demographic details, operative data (explorative access to the peritoneal cavity, time of operation, recovery parameters (time with IV analgesic medication, time to first oral fluid intake, time to first solid meal, time to discharge, and oncological parameters (lymph node harvest, TNM stage and resection margins were analyzed. Postoperative complications were also recorded. The two groups were retrospectively well matched with respect to demographic parameters and oncological status of the tumor. Results The median length of the midline incision was slightly longer (12 vs. 10 cm, p  Conclusions The Kocher’s incision approach for right- sided colon cancer is technically feasible, safe and overall very well tolerated. It can achieve the same standards of tumor resection and surgical field accessibility as the midline approach, while reducing postoperative recovery.

    Police officers are required to perform dynamic movements in unpredictable environments, the results of which can lead to injury. Early identification of poor movement patterns of a police population, and potential sub groups within this population, may provide opportunities to treat and minimise injury risks. The aim of this study was to profile the functional movement capabilities of an Australian state police force and potential sub groups through a retrospective cohort study. Retrospective data from an Australian State Police Force were provided for analysis (♂ n = 1155, mean (±SD) age = 31.34 ± 8.41 years: ♀ n = 357, mean age = 27.99 ± 8.02 years). Data consisted of Functional Movement Screen (FMS) assessment results of male and female trainees and qualified police officers with all assessments conducted by a qualified Police Physical Training Instructor. Significantly higher (U = 253863, p movement performance across all groups were the hurdle step and rotary stability. Generally, police personnel (both attested officers and recruits of both genders) of greater age have a lower functional movement capability when compared to younger personnel, with greater percentages scoring 14 or below on the FMS. Specific conditioning programs to improve strength, range of motion and stability during identified key movement types in those demonstrating poorer movement performance may serve to reduce injuries in police personnel.

    PURPOSE The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. MATERIALS AND METHODS A retrospective study of patients receiving root-shaped screw-type dental implants placed from January 2000 to December 2009 was conducted. 6385 implants were placed in 3755 patients. The following data were collected from the dental records and radiographs: patient's age, gender, implant type and surface, length, diameter, location of implant placement, bone quality, prosthesis type. The correlations between these data and survival rate were analyzed. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. RESULTS In all, 6385 implants were placed in 3755 patients (3120 male, 635 female; mean age 65 ± 10.58 years). 108 implants failed and the cumulative survival rate was 96.33%. There were significant differences in age, implant type and surface, length, location and prosthesis type (P.05). CONCLUSION Related factors such as age, implant type, length, location and prosthesis type had a significant effect on the implant survival. PMID:22259704

    The overall median lifespan of domestic dogs has been estimated to 9-12 years, but little is known about risk factors for mortality in aged and a priori healthy dogs. The objective of this retrospective cohort study was to determine which characteristics are associated with mortality in aged and a priori healthy guide dogs, in a retrospective cohort study of 116 guide dogs followed from a systematic geriatric examination at the age of 8-10 years old. A geriatric grid collected the clinical data and usual biological parameters were measured at the time of examination. Univariate (Kaplan-Meier estimates) and multivariable (Cox proportional hazard model) survival analyses were used to assess the associations with time to all-cause death. The majority of dogs were Golden Retrievers (n=48) and Labrador Retrievers (n=27). Median age at geriatric examination was 8.9 years. A total of 76 dogs died during follow-up, leading to a median survival time from geriatric examination of 4.4 years. After adjustment for demographic and biological variables, an increased alanine amionotransferase level (adjusted Hazard Ratio (adjusted HR), 6.2; 95% confidence interval [95%CI], 2.0-19.0; Pguide dogs. These results may be useful for preventive medical care when conducting a geriatric examination in working dogs. Copyright © 2016 Elsevier B.V. All rights reserved.

    To review the clinical findings in deep neck infections and identification predisposing factors of these complications. In this study, 270 patients with deep neck infections were studied retrospectively, study conducted in the Department of Ear, Nose and Throat, Dr. Shankarrao Chavan Government Medical College, Nanded, Maharashtra, India, from March 2013 to March 2016. Analysis showed that males are most likely to have deep neck space infections (DNSI). Odontogenic and tonsillar causes were the more frequent ones. Staphylococcus aureus and Streptococcus species were the microorganisms more commonly isolated. DNSI remains a common and challenging disease for otorhinolaryngologists, and should be treated on emergency basis. In developing countries, lack of adequate nutrition, poor oral hygiene, tobacco chewing, smoking and beetle nut chewing has led to an increased prevalence of dental and periodontal diseases. In present study, Odontogenic infections were the most common etiological factor for DNSI.

    Full Text Available Background: This study describes the significance and temporal evolution of incidentally detected, presumed, metal-induced reactive periprosthetic masses in patients with metal on metal (MoM hip arthroplasty and its management. The literature concerning the temporal evolution of these lesions is meagre and so it is still unclear, whether asymptomatic patients with periprosthetic collections should undergo revision. Materials and Methods: Patients with MoM hip replacements fitted with a recalled implant (ASR, DuPuy often undergo magnetic resonance imaging with metal artifact reduction sequences to look for complications. From a cohort of 136 asymptomatic patients, with 181 MoM hips, hips with a mention of periprosthetic masses in their reports at first presentation, and a repeat scan within 6 months to 3 years were selected for this retrospective study. Patients with complications such as loosening, osteomyelitis, and muscle/tendon tears were excluded from the study, and the final study cohort consisted of 55 MoM hips and 61 periprosthetic masses. Ethics committee approval is not required in our institution for retrospective studies. The followup scans of each patient were compared, and the periprosthetic masses were described to have progressed, regressed, or remained unchanged. Results: Comparison revealed that 29 of the 61 reactive masses remained unchanged, 20 regressed, while only 12 showed progression. The study, therefore, has maximum power as the outcome of interest, i.e., regression or unchanged status of the pseudotumors, was seen in approximately 80% (more than half of the study group. The P value of the study was < 0.005. Conclusion: Periprosthetic soft tissue masses are not uncommon in patients with MoM hips. The majority of them in asymptomatic individuals remain stable or regress in the short to medium term, and close followup or decisions on revision surgery may not be warranted in asymptomatic patients.

    Full Text Available Background: Mycobacterium leprae infection has recently been detected in wild armadillos in Brazil. Leprosy is still endemic in Brazil and although its transmission is mostly by person-to-person contact, many cases report no history of previously known leprosy contact. It has been suggested that other sources of M. leprae may contribute to the transmission of leprosy in some areas. Aim: Our objective was to investigate whether contact with armadillos is associated with leprosy. Methods: A case-control study was carried out in Brazil. Data was collected from 506 leprosy patients and 594 controls on exposure to armadillos and age, sex, place of birth and living conditions. Univariate analysis and unconditional logistic regression were conducted to investigate whether leprosy was associated with exposure to armadillos. Results: Direct armadillo exposure was reported by 68% of leprosy cases and by 48% of controls (P < 0.001 roughly doubling the risk of leprosy, with odds ratio (OR 2.0, 95% confidence interval (CI [1.36-2.99]. Conclusion: The results of this study suggest that direct exposure to armadillos is a risk factor for leprosy in Brazil.

    Full Text Available The preparation of music teachers in Portugal and Brazil is the focus of this text, which aims at presenting preliminary aspects of a study in progress in the context of higher education in both countries. Inspired by comparative education methodology, the present study is investigating official documents and academic curricula offered in Portugal and Brazil for the music teachers’ preparation to promote, in different ways, the comparative reflection with an emphasis on school education. The music teachers’ education in both countries was analyzed taking into account the following elements: educational context in Portugal and Brazil; music preparation prior to higher education, and the entrance criteria in the courses that are offered for music teachers; curricular elements of the courses; teaching practice and professional perspectives. The preliminary results of this comparative analysis demonstrate similarities and differences in the two contexts: 1 in both countries, music teachers for regular schools receive their degrees in higher education institutions, and in Portugal, beyond the Licenciatura in Music, a Music Education Master degree is demanded; 2 in both countries specific entrance tests are accomplished in the universities, demanding previous musical knowledge; 3 the balance among the musical and pedagogical preparation is one of the curricular objectives; 4 the teaching practice is an emphasized component in the teachers’ preparation; 5 in Portugal, student’s motivation for the work in the regular school appears to be larger than in Brazil.

    Ana Lúcia Brandimarte

    Full Text Available Abstract: Aim The aim of this paper is to analyze trends in the literature concerning benthic invertebrates in Brazil, mainly the number of published papers and approaches used. Methods The Ph.D. database of the Lattes Platform (CNPq was used as the source of information for the period 1970-2014. We searched for the terms “benthos”, “macroinvertebrates”, and “zoobenthos” in the titles and keywords of the papers listed on the platform. Papers were classified into the following categories: Systematics, Life History, Ecology, and Divulgation. These categories were further divided into subcategories. The percentage of papers in every major category and subcategory was calculated. Results The search introduced 1,573 papers, which were mainly related to Ecology and Systematics. From 1970 to 2009, the number of papers published per decade increased exponentially, and the upward trend continues. The number of papers concerning Systematics, especially in Taxonomy, is increasing. Of the papers in Ecology category, those about Structure, Dynamics, and Distribution of the fauna have been increasing since the 1980s, and there has been an evident increase in the production of papers related to environmental damage in the last decade. The rate of production of papers concerning the role of invertebrates in ecosystems and the effects of different Spatial Scales has been increasing since the 2000s. Conclusion There is a clear tendency towards the increased continuity of paper production concerning freshwater benthic invertebrates, and relatively new approaches as Conservation and Exotic Species are becoming relevant.

    The authors set out to examine qualitatively the use of antiepileptic drugs (AEDs) in a population of older adults in a nursing home setting, evaluating aspects such as specialist prescriptions and changes in dosage. This retrospective prevalence study was carried out in a state-funded nursing home that provides care and rehabilitation for elderly people. The first objective of the study was to determine the prevalence of AED use in this population. The second objective was to monitor AED dosage modifications during the fifteen-month study period, focusing on the safety and the tolerability of AEDs. In the period of time considered, 129 of 402 monitored patients received at least one anti-epileptic therapy. The prevalence of AED use was therefore 32%. Gabapentin was found to be the most commonly prescribed drug, with a frequency of 29%, and it was used mainly for anxiety disorders, psychosis, neuropathic pain and mood disorders.

    There is concern that the maternal mortality in ethnic minority women is significantly greater than that of Caucasian British women. The objective of this study was to compare the demographic and obstetric outcomes between these two groups. Data were collected retrospectively over a 2-year period from 148 index and 148 control cases. The study group had statistically similar maternal age, labour duration, blood loss and mode of delivery compared with Caucasian British women (p > 0.05). A total of 68% of Turkish women spoke little or no English; were more likely to be non-smokers and also more likely to be married to unemployed spouses (p = 0.0001). This is the first study comparing obstetric outcomes of immigrant Turkish women with their Caucasian British counterparts. There was no significant difference in maternal or fetal outcomes, which could be attributed to the 'healthy migrant' theory, coupled with increased vigilance in ethnic minority pregnancies.

    Full Text Available Acute toxicity is a frequent but avoidable cause of morbidity and mortality in children especially in developing countries, including India. Present study assesses their pattern with relation to different age groupings. This retrospective study was conducted among all hospitalised paediatric victims of acute accidental poisoning at the King George Medical University; Lucknow during 2010 -11. Their history, baseline characteristics, clinical course and outcome was studied. Most children were male of less than three years with 4% overall mortality. Kerosene oil was implicated in most cases. Childhood poisoning is commonest during 1-3 years with a male preponderance. Household poisons; especially kerosene oil was responsible for most cases which was consumed accidentally. Parents must be educated and warned to keep these toxic ingredients safely in suitable containers and out of reach of their beloved children.

    To evaluate the impact of training on nurses' satisfaction and perceived confidence using symptom protocols for remotely supporting patients undergoing cancer treatment. Retrospective pre-/post-study guided by the Knowledge-to-Action Framework. Interactive workshops at three ambulatory oncology programs in Canada. 107 RNs who provide remote support to patients with cancer. Workshops included didactic presentation, role play with protocols, and group discussion. Post-training, a survey measured satisfaction with training and retrospective pre-/post-perceived confidence in the ability to provide symptom support using protocols. One-tailed, paired t-tests measured change. Satisfaction with the workshop and perceived confidence in the ability to provide symptom support and use protocols. Twenty-two workshops, 30-60 minutes each, were conducted with 107 participants. Ninety completed the survey. Compared to preworkshop, postworkshop nurses had improved self-confidence to assess, triage, and guide patients in self-care for cancer treatment-related symptoms, and use protocols to facilitate symptom assessment, triage, and care. Workshops were rated as easy to understand, comprehensive, and provided new information on remote symptom management. Some specified that the workshop did not provide enough time for role play, but most said they would recommend it to others. The workshop increased nurses' perceived confidence with providing remote symptom support and was well received. Subsequent workshops should ensure adequate time for role play to enhance nurses' skills in using protocols and documenting symptom support.

    The impact of dermatology consultation on the care of children with oncologic conditions is unknown. To review outpatient dermatology visits and the resulting impact on diagnosis and management of pediatric oncology patients. Retrospective review of pediatric oncology patients with outpatient dermatology visits at a tertiary care center from 2008 to 2015. The most common dermatologic diagnoses in 516 patients were skin infections (21.3%) and nonmalignant skin eruptions (33.4%). A diagnosis of significant impact (ie, malignancy, adverse cutaneous drug reaction, graft-versus-host disease, varicella-zoster virus, or herpes simplex virus infection), was made at the dermatology clinic in 14.7% of visits. Consultation resulted in a change in diagnosis in 59.8% of patients, change in dermatologic management in 72.4% of patients, and change in management of noncutaneous issues in 12.4% of patients. The use of electronic medical records, the nongeneralizable study population, and the retrospective design represent potential limitations. Outpatient dermatology consultation can affect the care of pediatric oncology patients with respect to diagnosis and treatment of skin conditions and management of nondermatologic issues.

    Particularly during household fires, inhalation of hot air and smoke, and the formation of carboxyhaemoglobin and cyanide lead to respiratory tract and lung injury in small animals. Additionally, oxygenation is impaired in most cases. The aim of this retrospective study was to analyse smoke exposure, physical examination findings and clinical pathology results as well as their course in dogs and cats presented after smoke inhalation. Patient histories of dogs and cats that had been diagnosed with smoke inhalation between January 1, 2008 and August 31, 2013 were analysed retrospectively. Normality was tested using the Shapiro-Wilk test and analyses were performed using t-tests, the Chi-square test and Mann-Whitney U-test. P-values antibiotic treatment, corticoids, bronchodilators and cleaning of the animal. One cat died and 21 animals were discharged 0-6 days after presentation. Dogs and cats suffering from smoke inhalation were presented with respiratory disorders and dehydration. Outcome is good if the animals are treated early and adequately with oxygen and fluid therapy.

IHTS was found in 24 pure breeds. Bulldogs, Labrador Retrievers, Boxers, and Doberman Pinschers comprised 69%; mixed breeds comprised 17%. Average onset age was 29 months (range: 3 months to 12 years. First episode occurred before 48 months of age in 88%. Vertical (35%, horizontal (50%, and rotational (15% movements were documented. Possible trigger events were found in 21%. Mentation was normal in 93%. Distractions abated the tremor in 87%. Most dogs did not respond to antiepileptic drugs. Conclusions and Clinical Relevance. This retrospective study documents IHTS in many breeds including Labrador Retrievers, Boxers, and mixed breeds.

    Several robotic devices have been proposed for upper limb rehabilitation, but they differ in terms of application fields and the technical solutions implemented. The aim of this study was to compare the effectiveness of three different robotic devices for shoulder-elbow rehabilitation in reducing motor impairment and improving motor performance in post-stroke patients. Retrospective multi-center study. Inpatient rehabilitation hospital. Eighty-seven chronic and subacute post-stroke patients, aged 48-85 years. Data were obtained through a retrospective analysis of patients who underwent a 3-week rehabilitation program including robot-assisted therapy of the upper limb and conventional physical therapy. Patients were divided into three groups according to the robot device used for exercise training: 'Braccio di Ferro" (BdF), InMotion2 (IMT), and MEchatronic system for MOtor recovery after Stroke (MEMOS). They were evaluated at the beginning and end of treatment using the Fugl-Meyer (FM) and Modified Ashworth (MAS) clinical scales and by a set of robot measured kinematic parameters. The three groups were homogeneous for age, level of impairment, time since the acute event, and spasticity level. A significant effect of time (Probot device used. Further, the ES ranged from moderate to large for the remaining kinematic parameters except for the movement accuracy (mean distance, MD), which exhibited a small ES in the BdF and MEMOS groups. The motor function gains obtained during robot-assisted therapy of stroke patients seem to be independent of the type of robot device used for the training program. All devices tested in this study were effective in improving the level of impairment and motor performance. This study could help rehabilitation professionals to set-up comparative studies involving rehabilitation technologies.

    Fever of unknown origin (FUO) can be caused by many diseases, and varies depending on region and time period. Research on FUO in Japan has been limited to single medical institution or region, and no nationwide study has been conducted. We identified diseases that should be considered and useful diagnostic testing in patients with FUO. A nationwide retrospective study. 17 hospitals affiliated with the Japanese Society of Hospital General Medicine. This study included patients ≥18 years diagnosed with 'classical fever of unknown origin' (axillary temperature ≥38°C at least twice over a ≥3-week period without elucidation of a cause at three outpatient visits or during 3 days of hospitalisation) between January and December 2011. A total of 121 patients with FUO were enrolled. The median age was 59 years (range 19-94 years). Causative diseases were infectious disease in 28 patients (23.1%), non-infectious inflammatory disease in 37 (30.6%), malignancy in 13 (10.7%), other in 15 (12.4%) and unknown in 28 (23.1%). The median interval from fever onset to evaluation at each hospital was 28 days. The longest time required for diagnosis involved a case of familial Mediterranean fever. Tests performed included blood cultures in 86.8%, serum procalcitonin in 43.8% and positron emission tomography in 29.8% of patients. With the widespread use of CT, FUO due to deep-seated abscess or solid tumour is decreasing markedly. Owing to the influence of the ageing population, polymyalgia rheumatica was the most frequent cause (9 patients). Four patients had FUO associated with HIV/AIDS, an important cause of FUO in Japan. In a relatively small number of cases, cause remained unclear. This may have been due to bias inherent in a retrospective study. This study identified diseases that should be considered in the differential diagnosis of FUO.

    The objective of this 10 year, retrospective study is to evaluate the indications for the removal of titanium miniplates following osteosynthesis in maxillofacial trauma and orthognathic surgery. All patients who had miniplates placed in a Regional Oral and Maxillofacial Department between January 1998 and October 2007 were included. The following variables were recorded: patient gender and age, number of plates inserted, indications for plate placement, location of plates, number and location of plates removed, indications for plate removal, time between insertion and removal, medical co-morbidities, and the follow-up period. During the 10 years of the study, 1247 titanium miniplates were placed in 535 patients. A total of 32 (3%) plates were removed from 30 patients. Superficial infection accounted for 41% of all plates removed. All complications were minor and most plates were removed within the first year of insertion. A low removal rate of 3% suggests that the routine removal of asymptomatic titanium miniplates is not indicated.

    Few prospective studies have attempted to estimate the rate of decline of essential tremor (ET) and these were over a relatively short time period (less than 10 years). We performed a long-term study of severity stages in ET using the Glass Scale scoring system. Fifty consecutive patients with severe ET were included. We retrospectively obtained Glass Scale scores throughout the patient's life. Common milestone events were used to help recall changes in tremor severity. According to the Glass Scale, the age distributions were as follows: score I, 40±17 years, score II, 55±12 years, score III, 64±9 years, and score IV, 69±7 years. A significant negative correlation between age at first symptom and rate of progression was found (r = -0.669, pScale may be a useful tool to determine severity stages during the course of ET in a manner similar to the Hoehn and Yahr Scale for Parkinson's disease.

    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.

MATERIALS AND METHODS A retrospective study was conducted from January 2014 to December 2015 on patients admitted in labour room of Dr. B. R. Ambedkar Medical College and Hospital and assessed for MSL, mode of delivery and foetal outcome. RESULTS Out of the 1661 deliveries 195 (11.73 % were complicated with MSL. Chi square test was applied to analyse Grades of meconium and APGAR score at 95 % confidence and p value of < 0.05 was obtained which was statistically significant. CONCLUSION MSL alone is not an indication for Caesarean Section and is not associated with adverse neonatal outcome. Increase in the grades of MSL is associated with more adverse outcome.

    Full Text Available Background and Purpose. This study investigated the cardiopulmonary response and safety of exercise testing at peak effort in people during the chronic stage of stroke recovery. Methods. This retrospective study examined data from 62 individuals with chronic stroke (males: 32; mean (SD; age: (12.0 yr participating in an exercise test. Results. Both males and females had low cardiorespiratory fitness levels. No significant differences were found between gender for peak HR (=0.27, or VO2 peak (=0.29. Males demonstrated higher values for minute ventilation, tidal volume, and respiratory exchange ratio. No major adverse events were observed in the exercise tests conducted. Discussion and Conclusion. There are differences between gender that may play a role in exercise testing performance and should be considered when developing exercise programs. The low VO2 peak of this cohort of chronic stroke survivors suggests the need for participation in exercise interventions.

    It is well known that with increasing age, fertility potential decreases in women. Since some of the women who undergo assisted reproductive technology (ART) treatments are very young patients or young donors, fecundity investigation seems necessary in this group. Data from patients who underwent in vitro fertilisation/intra-cytoplasmic sperm injection (IVF/ICSI) over 20 years were analysed retrospectively. The records of 407 infertile patients aged 17-25 years (study group) and 407 infertile patients aged 26-35 years (control group) were collected. The number of follicles > 14 mm, retrieved oocytes, MII oocytes, cleaved embryos in both IVF and ICSI cycles were significantly higher in the study group when compared with the control group (p˂0.001). However, the rates of chemical pregnancies were similar between the two groups. It therefore seems unlikely that younger age has a positive effect in predicting infertility treatment outcomes.

    This case study identifies the influence and mechanisms that the alcohol industry in Brazil has been able to bring to bear to maintain self-regulation in the marketing of beer and many wines set against a trend of increasing alcohol consumption in Brazil, particularly among young people and women. It identifies the forms of power and strategies used by the alcohol industry in Brazil that may be useful for other countries to consider in seeking to move from self-regulation to state regulation of alcohol marketing. A review was conducted of recent legal documents and court cases, as well as the activities of alcoholic beverage industries. Because of an exemption, Brazilian law had established that both beer and many wines are not alcoholic beverages for marketing purposes. These beverages are subjected to industry self-regulation codes. Research shows that beer and wine marketing often violates industry codes, with little or no enforcement of penalties for non-compliance. Attempts to include beer and wine in the legal definition of alcohol have been opposed by the alcohol industry, and the courts have delegated responsibility to the legislature. The recent legal activities surrounding alcohol sales during the 2014 World Cup games in Brazil provide evidence of the alcohol industry's influence on the legislative process. The alcohol industry in Brazil plays a significant role in the formulation of public policies on alcohol, especially regarding the regulation of marketing. This power is exercised by strong lobbying of government officials responsible for public policies. © 2016 Society for the Study of Addiction.

    It was tried to retrospectively identify HIV infections in recipients of transfusions from donors who were tested HIV positive at a subsequent donation. These lookback data were traced back to answer the following questions: 1. How many transfusion recipients were infected before the start of the routine HIV testing in 1985? 2. How great is the risk of HIV infections from infected but not yet HIV antibody-positive donors? 3. Furthermore, the transfusion of HIV-infected transfusion recipients was traced back to the involved donor to establish causality. Retrospective ('lookback') study. HIV Study Group of the Red Cross Blood Banks of the Federal Republic of Germany. Preceding donations of HIV antibody-positive repeat donors were traced back to the transfusion recipients in order to establish their HIV antibody status. In a second lookback study, HIV-infected transfusion recipients and their corresponding donors were investigated after they had been reported to the blood bank as infected by transfusion-associated HIV. None. Recipients of 156 respectively 133 transfusions from repeat donors found to be Western blot-positive were investigated from 1985 to 1987 and from 1987 to 1992, respectively. About 50% of the recipients had died. About 40% of the recipients could not be examined, because they either were not available for testing or refused to be tested or because it was impossible to clarify the fate of the blood products. 25 HIV recipients were identified from 1981 to 1985, when routine HIV testing began. Nine transfusion-associated HIV infections were identified from 1985 to 1992. 25 million units of blood were prepared during this period. The risk of HIV transmission by tested transfusions is extremely rare (in the order of 1:1 million). The second lookback study suggests that in more than 50% of the blood recipients in whom HIV infection was attributed to transfusion, a causal relationship to an infected donor could not be established.

    Organ dose estimation for retrospective epidemiological studies of late effects in radiotherapy patients involves two challenges: radiological images to represent patient anatomy are not usually available for patient cohorts who were treated years ago, and efficient dose reconstruction methods for large-scale patient cohorts are not well established. In the current study, we developed methods to reconstruct organ doses for radiotherapy patients by using a series of computational human phantoms coupled with a commercial treatment planning system (TPS) and a radiotherapy-dedicated Monte Carlo transport code, and performed illustrative dose calculations. First, we developed methods to convert the anatomy and organ contours of the pediatric and adult hybrid computational phantom series to Digital Imaging and Communications in Medicine (DICOM)-image and DICOM-structure files, respectively. The resulting DICOM files were imported to a commercial TPS for simulating radiotherapy and dose calculation for in-field organs. The conversion process was validated by comparing electron densities relative to water and organ volumes between the hybrid phantoms and the DICOM files imported in TPS, which showed agreements within 0.1 and 2%, respectively. Second, we developed a procedure to transfer DICOM-RT files generated from the TPS directly to a Monte Carlo transport code, x-ray Voxel Monte Carlo (XVMC) for more accurate dose calculations. Third, to illustrate the performance of the established methods, we simulated a whole brain treatment for the 10 year-old male phantom and a prostate treatment for the adult male phantom. Radiation doses to selected organs were calculated using the TPS and XVMC, and compared to each other. Organ average doses from the two methods matched within 7%, whereas maximum and minimum point doses differed up to 45%. The dosimetry methods and procedures established in this study will be useful for the reconstruction of organ dose to support

    Fumaric acid esters (FAE) have been used for over 30 years in the management of psoriasis. There have been a number of case reports linking the use of FAE with nephrotoxicity, including acute renal injury and Fanconi syndrome. However, one large multicentre retrospective trial showed no evidence of renal dysfunction with FAE. The aim of this study was to determine the number of patients in our institution being treated with FAE who developed significant proteinuria or renal dysfunction. This was a single-centre retrospective study assessing all patients on FAE who attended for follow-up during an 18-week period between February and June 2015. Demographics, comorbidities, duration and dose of treatment with FAE, proteinuria, renal function and other biochemical serum abnormalities were recorded. One hundred and twenty-seven patients were included in the study. Eighty-two patients had proteinuria detected at some stage during treatment with FAE, and 18 of these had persistent proteinuria (positive in at least three consecutive specimens, 12 weeks apart). Six patients (five female) developed proximal tubular dysfunction (PTD). The risk factors for the development of PTD appear to be lower bodyweight (P = 0.03), higher dose per weight (P = 0.03) and longer duration of treatment (P = 0.03). Renal dysfunction improved on discontinuation or dose reduction in FAE. Fumaric acid esters are frequently associated with transient or persistent proteinuria. Significant renal dysfunction is rare and usually reversible on dose reduction or discontinuation of FAE. This study highlights the importance of screening for proteinuria. Higher doses per weight of treatment and longer duration of FAE therapy are likely risk factors for PTD. © 2016 European Academy of Dermatology and Venereology.

    Full Text Available ABSTRACT Objective: analyze trends in fertility rates and associations with perinatal outcomes for adolescents in Santa Catarina, Brazil. Methods: a population-based study covering 2006 to 2013 was carried out to evaluate associations between perinatal outcomes and age groups, using odds ratios, and Chi-squared tests. Results: differences in the fertility rate among female adolescents across regions and time period were observed, ranging from 40.9 to 72.0 per 1,000 in mothers aged 15-19 years. Adolescents had fewer prenatal care appointments than mothers ≥20 years, and a higher proportion had no partner. Mothers aged 15-19 years were more likely to experience preterm birth (OR:1.1; CI:1.08-1.13; p<0.001, have an infant with low birthweight (OR:1.1; CI:1.10-1.15; p<0.001 and low Apgar score at 5 minutes (OR:1.4; CI:1.34-1.45; p<0.001 than mothers ≥20 years, with the odds for adverse outcomes greater for those aged 10-14 years. Conclusion: this study provides evidence of fertility rates among adolescents remaining higher in regions of social and economic deprivation. Adolescent mothers and their infants more likely to experience adverse perinatal outcomes. Nurses, public health practitioners, health and social care professionals and educators need to work collaboratively to better target strategies for adolescents at greater risk; to help reduce fertility rates and improve outcomes.

    Lupus anticoagulant (LAC) testing is challenging. Most data are derived from a well-controlled study environment with potential alterations to daily routines. The aim of this retrospective cohort study was to assess the capacity of various LAC screening tests and derived mixing tests to predict a positive result in subsequent confirmation tests in a large cohort of patients. In 5832 individuals, we retrospectively evaluated the accuracy of the aPTT-A, aPTT-LAscreen, aPTT-FS and dRVVTscreen and of their derived mixing tests in detecting a positive confirmation test result within the same blood specimen. The group differences, degree of correlation and the predictive accuracy of LAC coagulation tests were analysed using the Mann-Whitney U test, the Spearman-rank-correlation and by area under the receiver operating characteristic curve (ROC-AUC) analysis. ROC-AUCs were compared with the Venkatraman´s permutation test. The pre-test probability of patients with clinically suspected LAC was 36% in patients without factor deficiency or anticoagulation therapy. The aPTT-LAscreen showed the best diagnostic accuracy with a ROC-AUC of 0.84 (95% CI: 0.82 - 0.86). No clear advantage of the dRVVT-derived mixing test was detectable when compared to the dRVVTscreen (P = 0.829). Usage of the index of circulating anticoagulant (ICA) did not improve the diagnostic power of respective mixing tests. Among the parameters evaluated, aPTT-LAscreen and derived mixing test parameters were the most accurate tests. In our study cohort, neither other mixing test nor the ICA presented any further advantage in LAC diagnostics.

    Injuries (unintentional and intentional) are the main cause of death and disability worldwide, including Jordan. The main purpose of this hospital-based retrospective study was to identify characteristics, causes, and risk factors of unintentional injuries and violence among all adult patients who approached the Accidents and Emergency department because of injury in Northern Jordan. Data were collected retrospectively from four major hospitals from January 2008 to January 2013. A total of 2425 Jordanian individuals who accessed and were treated by the four hospitals were included in this study. The findings show that the majority of patients who approached the Accidents and Emergency departments in the four hospitals were males (n = 2044, 87.16%) versus females (n = 301, 12.8%). Violence was the most common reason of injury (70.66%), followed by road traffic crashes (23.21%). The most common anatomical locations of reported injuries were the head (38.74%), followed by abdomen/pelvis and lower back, among males and females (9.93%). Violence had a high significant effect on the site of injuries. Patients who had been injured to the head because of a stab wound or fighting were substantially over-involved in head injuries, with injury rates 3.88 and 7.51 times higher than those who had been injured to the head due to gunshot, respectively. Even patients who had been injured to the head because of assault show much higher involvement in injury risk than non-assault patients (Odds Ratio = 8.46). These findings highlight the need for a large national study to confirm the findings. It also draws attention to the importance of public awareness and to special injury prevention programs that not only focus on saving lives and lessening the number of injuries, illnesses, and fatalities, but also to limit the social and economic burden of injury among adults in Northern Jordan.

    Retrospective gating on animal studies with microCT has gained popularity in recent years. Previously, we use ECG signals for cardiac gating and breathing airflow or video signals of abdominal motion for respiratory gating. This method is adequate and works well for most applications. However, through the years, researchers have noticed some pitfalls in the method. For example, the additional signal acquisition step may increase failure rate in practice. X-Ray image-based gating, on the other hand, does not require any extra step in the scanning. Therefore we investigate imagebased gating techniques. This paper presents a comparison study of the image-based versus signal-based approach to retrospective gating. The two application areas we have studied are respiratory and cardiac imaging for both rats and mice. Image-based respiratory gating on microCT is relatively straightforward and has been done by several other researchers and groups. This method retrieves an intensity curve of a region of interest (ROI) placed in the lung area on all projections. From scans on our systems based on step-and-shoot scanning mode, we confirm that this method is very effective. A detailed comparison between image-based and signal-based gating methods is given. For cardiac gating, breathing motion is not negligible and has to be dealt with. Another difficulty in cardiac gating is the relatively smaller amplitude of cardiac movements comparing to the respirational movements, and the higher heart rate. Higher heart rate requires high speed image acquisition. We have been working on our systems to improve the acquisition speed. A dual gating technique has been developed to achieve adequate cardiac imaging.

    Full Text Available INTRODUCTION Bortezomib is a selective inhibitor of the proteosoma that is used in multiple myeloma. In combination with other antineoplastic drugs, it has a well-documented impact in progression-free survival rates and overall survival rates with standard doses (1.3-1.5 mg/m2. However, up to 88% of patients on standard doses have unwanted side effects (neutropenia, neuropathy or anemia. Standard dose (1.3 mg/m2 is used in almost all patients and low dose (0.7-0.8 mg/m2 is reserved for patients with kidney disease and neuropathy. OBJECTIVE We aim to describe clinical, cytological, and cytometric outcomes, as well as overall survival and side effects of low dose versus standard dose of bortezomib in our institution. METHODS Retrospective, descriptive study based on data recovered from clinical charts of 48 multiple myeloma patients treated in our hospital between 2011 and 2013. We included data on age, gender, type of multiple myeloma, serum albumin, serum creatinine, beta 2 microglobulin, calcemia, imaging studies, disease stage, pre-and post-therapy bone marrow studies, adverse events and rate of progression. We also recorded events like date of death or of the last medical appointment. RESULTS Forty-eight multiple myeloma patients were treated with bortezomib-cyclophosphamide-dexamethasone. Twenty-one patients received low dose and 27 patients were treated with the standard dose. No statistical differences between the two groups were found for clinical response (p=0.6, cytological response (p=0.28, flow cytometric response (p= 0.3, rate of adverse effects and overall survival rates. CONCLUSION This retrospective analysis suggests that lower doses of bortezomib have similar effects in disease control measured by flow cytometry and cytology compared to standard doses in multiple myeloma patients.

    Vaginal penetration phobia is a common and distressing problem world.wide. It interferes with vaginal penetrative sexual relations, and leads to unconsummated marriage (UCM). This problem may be heightened in Arab women, due to cultural taboos about pain and bleeding, that may be associated with the first coital experience after marriage. Data about this problem is scarce in Arab societies. The aim of this study was to evaluate the response of these women and their husbands to an individualized, psychotherapeutic assessment and treatment to resolve this problem. Retrospective descriptive in a general gynecology community setting over a 6-year period. The study involved a retrospective sequential cohort of 100 Arab couples with UCM due to the woman's VPP. They were evaluated by a female gynecologist in out patient clinics. Data was collected through chart review, and telephone interviews. Final analysis was performed on 100 Arab couples, who satisfied the inclusion criteria. They were followed up to assess their response to an individualized, structured treatment protocol. The treatment combined sex education with systematic desensitization, targeting fear and anxiety as.sociated with vaginal penetration. A total of 96% of the studied group had a successful outcome after an average of 4 sessions. Penetrative intercourse was reported by the tolerance of these women; further pregnancy was achieved in 77.8 % of the infertile couples. Insufficient knowledge of sexual intercourse is a major contributor to the development of VPP in the sampled population. It appears that they respond well to an individualized, structured treatment protocol as described by Hawten 1985 (regardless of other risk factors associated with vaginismus).

    OBJECTIVE The authors' objectives in this study were to evaluate their institutional protocol and create recommendations for radiographic imaging in infants with torticollis, with or without plagiocephaly, based on a retrospective clinical analysis and literature review. METHODS A retrospective analysis was conducted to identify infants with torticollis who were evaluated by the craniofacial team. The following patients were identified: those who underwent imaging in the form of radiography, CT scanning, or MRI; those who had a secondary diagnosis or additional clinical finding as the indication for imaging; and those with persistent torticollis despite completion of recommended repositioning techniques and physical therapy (PT). RESULTS A total of 683 infants between the ages of 1 day and 335 days (mean age 141.6 days) were referred for management of torticollis. Initial imaging was performed in 48 patients, of whom 44 were identified as having a diagnosis other than torticollis or a significant clinical finding as the indication for imaging. The remaining 4 patients (0.6% of the torticollis population) underwent imaging and did not have an additional diagnosis or a significant clinical finding. There were no abnormal radiological findings in these patients. Of the 639 patients diagnosed with congenital torticollis who did not have a secondary diagnosis that required initial imaging, 99.2% (634 patients) achieved resolution of torticollis with recommended repositioning techniques and completion of PT and without radiography, CT, or MRI. CONCLUSIONS Within the limits of this retrospective study and supporting literature, the authors provide the following recommendations regarding radiographic imaging of infants with congenital torticollis. 1) Clinical examination is sufficient in the diagnosis of congenital torticollis in infants. Radiography, CT scanning, and MRI are not necessary. 2) In cases in which additional clinical or neurological findings are present

    Leprosy remains an important public health problem in Brazil where 28,761 new cases were diagnosed in 2015, the second highest number of new cases detected globally. The disease is caused by Mycobacterium leprae, a pathogen spread by patients with multibacillary (MB) leprosy. This study was designed to identify population groups most at risk for MB disease in Brazil, contributing to new ideas for early diagnosis and leprosy control. A national databank of cases reported in Brazil (2001-2013) was used to evaluate epidemiological characteristics of MB leprosy. Additionally, the databank of a leprosy reference center was used to determine factors associated with higher bacillary loads. A total of 541,090 cases were analyzed. New case detection rates (NCDRs) increased with age, especially for men with MB leprosy, reaching 44.8 new cases/100,000 population in 65-69 year olds. Males and subjects older than 59 years had twice the odds of MB leprosy than females and younger cases (OR = 2.36, CI95% = 2.33-2.38; OR = 1.99, CI95% = 1.96-2.02, respectively). Bacillary load was higher in male and in patients aged 20-39 and 40-59 years compared to females and other age groups. From 2003 to 2013, there was a progressive reduction in annual NCDRs and an increase in the percentage of MB cases and of elderly patients in Brazil. These data suggest reduction of leprosy transmission in the country. Public health policies for leprosy control in endemic areas in Brazil should include activities especially addressed to men and to the elderly in order to further reduce M. leprae transmission.

    To investigate the distribution of blood hemoglobin levels in healthy blood donors and elite athletes, a retrospective cohort study from 2001 to 2005 of candidate blood donors and elite rowers in Denmark was performed. Eighty-five thousand eight hundred and forty-six blood donors were identified...... (36 962 males), and 3.9% of the males had a blood hemoglobin above 10.5 mM, equalling a hematocrit of 51% and, 1.6% of the females had hemoglobin above 9.7 mM, corresponding to a hematocrit above 47%. One thousand four hundred and six rowers (1116 males) were investigated and 10.4% of the males and 8.......3% of the females demonstrated values above the recommended limit for athletic competition. Thus, the prevalence of a high hemoglobin value was greater in the rowers, of both gender, than in the candidate blood donors (Phemoglobin levels in blood are seen regularly in normal...

    This brief report examines the implementation of a hybrid transitional-supported employment program using a social enterprise model to improve work skills and work behavior of people with psychiatric disabilities. The subjects of this study included 25 consumers enrolled in a social enterprise café training program between May 2006 and December 2007. Work behavior assessments and supported employment tenure were retrospectively analyzed. All training participants who completed the 20-month training program demonstrated significant improvement in work behavior before leaving the transitional training at the café. Individuals who completed the transitional training at the café went on to sustain competitive employment for an average of 44 weeks. The social enterprise model is deemed helpful in assisting people with psychiatric disabilities to improve their employment outcomes.

    Mesotherapy, or intradermal therapy, is a therapeutic approach that is gaining popularity, but there is still a significant lack of information on its mechanisms of action or the pharmacokinetics of the therapeutic regimens. This retrospective study on 220 records compared the short-term and long-term effects of mesotherapy using a mixture of drugs versus normal saline solution in the treatment of patients with chronic spinal pain (CSP). At the end of treatment, outcome measures showed a significant improvement (PMesotherapy was effective in patients affected by CSP, with high patient satisfaction reported irrespective of the agent used. Considering the risks and costs of drugs, normal saline solution appears to be the best agent in cost-benefit terms for treating localized pain by mesotherapy in CSP.

    The incidence of bone metastasis in head and neck Squamous cell carcinoma is very uncommon. This retrospective study was done to identify the frequency, clinical presentation, and the clinical course of the metastatic disease to bone from head and neck primary. Out of 624 patients of head and neck cancers seen in our clinic 6 patients developed metastasis to solitary or multiple bones during the course of the disease. Postoperative patients had multiple bone involvement whereas others had solitary bone involvement. Main bones involved were parietal bone of skull, shaft of humerus and femur, sacrum, and ribs. All the patients had survival of few months only after developing metastasis. Improvement in technology has resulted in improved results in advanced head and neck cancer patients; hence measures should be taken for complete responders to diagnose this metastasis early and treat them appropriately.

    Trichoepithelioma is a benign follicular tumor, affects young female adults, and has three clinical forms: solitary, multiple, or desmoplastic. Diagnosis represents a clinical challenge for the dermatologist. There are many differential diagnoses, and the most important is basal cell carcinoma because they share histological features. It has good prognosis and therefore treatment is usually for aesthetic purposes, even though it is associated with recurrence. This is a retrospective study carried out from January 1993 to December 2012 of all the patients who were diagnosed by histopathology to have trichoepithelioma in the dermatology department of the Dr. Manuel Gea González General Hospital. There were 47 cases, of which 70.2% were female, with an average age of 43.6 years. Solitary trichoepithelioma was the most frequent clinical form (66%) and only three of 14 cases of multiple trichoepithelioma had a positive family history.

    Full Text Available AbstractThe literature indicates damage to students' mental health in cases of school violence. The aim of this retrospective study was to evaluate the psychological impact of school victimization in university students, and to analyze the association between PTSD symptoms and variables related to school victimization. 691 University students responded to the Portuguese version of the Student Alienation and Trauma Survey (SATS. Clinically significant scores in the subscales ranged from 4.7% (somatic symptoms to 20% (hypervigilance, with frequent symptoms described in the literature resulting from school victimization, such as depression, hopelessness, cognitive difficulties, and traumatic event recollection. Additionally, 7.8% of participants presented PTSD symptoms after suffering their "worst school experience". Associations were found between PTSD symptoms and the level of distress after the experience, as well as the perceived benefits after the event, and duration. The results confirm the potential detrimental effects of school victimization, and may be useful to further investigations on this topic.

    2012-06-01

    A retrospective study of spinal cord lesions in goats was conducted to identify the range of lesions and diseases recognized and to make recommendations regarding the best tissues to examine and tests to conduct in order to maximize the likelihood of arriving at a definitive etiologic diagnosis in goats with clinical signs referable to the spinal cord. Twenty-seven goats with a spinal cord lesion were identified. The most common lesion recognized, in 13 of 27 goats, was degenerative myelopathy. Eight goats with degenerative myelopathy were diagnosed with copper deficiency. Non-suppurative inflammation due to caprine arthritis encephalitis virus, necrosis due to parasite larvae migration, and neoplasia were each diagnosed 3 times. Based on these findings, it is recommended that, in addition to careful handling and histologic examination of the spinal cord, samples of other tissues, including the brain, liver, and serum, be collected for ancillary testing if warranted.

    The objective of the present work was to ascertain the date in which hepatitis E virus (HEV) was introduced in the Spanish pig population. For this, a serological retrospective study was carried out using archived sera. A total of 2871 serum samples gathered between 1985 and 1997 and collected in 208 farms of Spain were tested for anti-HEV IgG by an in-house ELISA. Of the 2871 sera analyzed by ELISA, 1390 were positive for anti-HEV antibodies (48.4%, 95% CI: 46.9-49.9%) and that corresponded to 204/208 farms (98%, 95% CI: 96.1-99.9%) having at least one positive pig. Our results show that HEV was present and widespread in Spanish swine farms at least since 1985. Any significant changes in prevalence were detected from 1 year to another and therefore, HEV infection in swine should be considered endemic in Spain.

    We present a retrospective review of a series of patients from our Service submitted to surgical extra-anatomical grafts. Correlation between diverse variants and ulterior obliteration by thrombosis or infection of the surgical wounds is analyzed. The series included 133 patients surgically treated between 1986 and 1991. The studied variants were: sex, age, type of graft, the material used, length and type of anesthesia, presentation of hypotension during the surgical intervention, diabetes, platelet recount. Fourteen patients (11%) presented early graft obliteration and 15 (11%) presented an infection of their surgical wound. Only the platelet variant showed statistical differences in patients presenting infection. A high recount of platelets could be a factor risk of infection.

    To examine paramedical (chiropractic, physiotherapy and massage therapy) utilization among high-level BMX athletes following sport-related injury at the 2007 UCI World Championships. Retrospective analysis was conducted on a dataset from international male and female BMX athletes (n = 110) who sustained injury in training and competition at the 2007 BMX World Championships. Fifty percent of individuals aged 8-17 presented to a chiropractor versus 32% to physiotherapists and 18% to massage therapists. There was a significant difference in paramedical practitioner choice when comparing the sample across the different locations of injury. Specifically, the proportion of individuals presenting for treatment to chiropractors (84%) was much higher than to physiotherapists/massage therapists (16%) for spine or torso complaints. Utilization of chiropractors by BMX athletes may be higher than utilization of other paramedical professionals as suggested by this study. Chiropractors appear to be the paramedical practitioner of choice in regards to spine and torso related complaints.

    To evaluate the efficacy and toxicity of helical tomotherapy (HT) in the management of spine chordomas when proton therapy is unavailable or non-feasible. Between 2007 and 2013, 30 patients with biopsy-proven chordomas were treated by HT in five French institutions. Information regarding local control (LC), overall survival (OS), progression-free survival (PFS) and metastasis-free survival (MFS) was collected. Clinical efficacy, toxicity and treatment quality were evaluated. Two-year actuarial LC, OS, PFS and MFS were 69.9%, 96.7%, 61.2% and 76.4%, respectively. HT treatments were well tolerated and no Grade 4-5 toxicities were observed. HT permitted the delivery of a mean dose of 68 Gy while respecting organ at risk (OAR) dose constraints, in particular in the spinal cord and cauda equina. This multicentric, retrospective study demonstrated the feasibility of HT in the treatment of spine chordomas, in the absence of hadron therapy.

This is a retrospective study reporting the clinical characteristics and outcome of 138 cases of viral meningitis and meningoencephalitis in a real life experience at a referral centre in Turin, Northern Italy. Enteroviruses were predominant in younger patients who were mainly presenting with signs of meningitis, had shorter hospital admission and absence of complications, whereas herpesviruses had more often signs of encephalitis, were more frequent in elderly patients, had longer hospital admission and frequent complications and sequelae. Two main clinical entities with different epidemiology, clinical aspects and prognosis may be identified within the group of viral CNS inefctions.

    Ceramic materials that are widely employed in dental prosthetics and repairs exhibit luminescent properties. Because of their use in the body, these materials are potentially of interest in situations where retrospective dosimetry for individuals is required but where monitoring was not planned. The luminescent properties of dental ceramics obtained in Germany, Spain and the UK were examined. Linear dose-response characteristics were obtained in the range <100 mGy to 10 Gy using thermoluminescence (TL), optically stimulated luminescence and infrared-stimulated luminescence measurement techniques. Measurements of time-resolved luminescence were also performed to examine the nature of the luminescence recombination under visible (470 nm) and IR (855 nm) stimulation. The results obtained by TL and optically stimulated techniques suggest that there may be deeper traps than previously observed in certain types of dental ceramic. Such traps may be less susceptible to optical and athermal fading than was reported in earlier studies. (author)

    Full Text Available BACKGROUND Myringoplasty is the surgical repair of tympanic membrane. Most commonly used techniques are onlay and inlay. Common graft materials include temporalis fascia and tragal perichondrium. MATERIALS AND METHODS In this present retrospective study involving 60 patients with 30 each in onlay and inlay group who underwent myringoplasty by transmeatal approach using tragal perichondrial graft. RESULTS We found success rate of 90% in onlay and 93.3% in inlay method, difference of which was not statistically significant. Degree of hearing improvement was 15.95 dB for onlay group and 16.48 in inlay group and the difference was again not significant. CONCLUSION The only advantage of onlay procedure was consumption of little less amount of time. Apart from that, we concluded that none of these methods are superior to other.

    The purpose of this retrospective study was to analyse the etiology, frequency and outcome of toxicological cases recorded by the consultation service of the Swiss Toxicological Information Centre (STIC) hotline over a 10-year period, from 1997 to 2006. A detailed analysis of this database indicates that common human drugs not intended for use in animals, as well as pesticides and toxic plants represent the most prominent hazards involved in the reported cases of animal poisonings. The comparison with a previous survey from the years 1976 - 1985 revealed new toxic risks due to the accidental uptake of cannabis products, castor seeds or chocolate by dogs. In addition, there is a striking increase of serious poisonings with pyrethroids in cats. The follow-up reports delivered by veterinarians also reflect novel pharmacological and technological trends in the management of poisonings.

    No study has investigated the admission echocardiographic characteristics of acute heart failure (AHF) patients who are resistant to conventional diuretics and require tolvaptan. We retrospectively analyzed the echocardiographic characteristics of AHF patients who were resistant to conventional diuretics and took tolvaptan (tolvaptan group: 26 patients), and compared them to those who were sensitive to conventional diuretics (conventional group: 180 patients). The tolvaptan group had a higher left atrial volume index (96.0 ± 85.0 mL/m2 vs. 45.8 ± 25.9 mL/m2, p tolvaptan had no significant echocardiographic differences compared to the non-responders. The admission echocardiographic characteristics of AHF patients requiring tolvaptan included a larger left atrium, inferior vena cava, and more severe tricuspid regurgitation. Echocardiography may provide useful information for the early and appropriate initiation of tolvaptan.

    INTRODUCTION Gait Deviation Index (GDI) describes the overall gait quality and summarizes it into a single score based upon three-dimensional gait analysis (3DGA). In the Region of Southern Denmark, children with cerebral palsy (CP) are referred to 3DGA if surgical intervention is considered...... on different treatments. ACKNOWLEDGEMENTS We like to thank Physiotherapist, Lisbeth Torp-Pedersen and Physiotherapist, Mirjam Gismervik Bjødstrup for conducting the gait analysis...... and subsequently, as a follow-up. Thus, the effect of treatment on gait quality in children with CP may be quantified. In a retrospective study we investigated the effect of treatment on gait quality (measured by GDI) in children with CP. METHODS Data from children (
