    Despite most of the cytogenetic research is focused on monocentric chromosomes, chromosomes with kinetochoric activity localized in a single centromere, several studies have been centered on holocentric chromosomes which have diffuse kinetochoric activity along the chromosomes. The eukaryotic organisms that present this type of chromosomes have been relatively understudied despite they constitute rather diversified species lineages. On the one hand, holocentric chromosomes may present intrinsic benefits (chromosome mutations such as fissions and fusions are potentially neutral in holocentrics). On the other hand, they present restrictions to the spatial separation of the functions of recombination and segregation during meiotic divisions (functions that may interfere), separation that is found in monocentric chromosomes. In this study, we compare the diversification rates of all known holocentric lineages in animals and plants with their most related monocentric lineages in order to elucidate whether holocentric chromosomes constitute an evolutionary advantage in terms of diversification and species richness. The results showed that null hypothesis of equal mean diversification rates cannot be rejected, leading us to surmise that shifts in diversification rates between holocentric and monocentric lineages might be due to other factors, such as the idiosyncrasy of each lineage or the interplay of evolutionary selections with the benefits of having either monocentric or holocentric chromosomes.

    Fetus small for gestational age (SGA) screening rate is evaluated around 21,7 % in France. Recommendations were developed to improve the efficiency of ultrasound conducted in the third trimester (T3), because neonatal consequences can be significant. This study aims to evaluate screening of SGA during T3 ultrasound and to describe causes for failure and differences with the recommendations of CNGOF. All children born between 2011 and 2012 with a birth weight below the 3rd percentile were included in this observational, retrospective, monocentric study. We noted that the diagnosis of SGA was placed on file. Then, as recommended by the CNGOF, we calculated estimated fetal weight (EFW) with Hadlock 3 and Hadlock 4, and the corresponding percentiles, using the biometrics from the ultrasound report. We thus could evaluate a new screening rate with SGA fetus identified through this technique. A total of 142 patients were included. By calculating correctly all EFW and checking abdominal circumference percentiles, the screening rate of SGA fetuses with T3 ultrasound increased from 40 % to 50 % and the overall screening rate (clinical and ultrasound) from 54 % to 66 %. By following the recommendations we found a real improvement in fetal SGA screening rates to T3 ultrasound with a potential benefit for their care. Copyright © 2016 Elsevier Masson SAS.

    There is no consensus on the standard treatment of gastric mucosa-associated lymphoid tissue (MALT) lymphoma for Helicobacter pylori-negative patients and for patients with persistent disease despite H. pylori eradication. To evaluate the comparative efficacy and safety of alkylating agents and rituximab alone or in combination. In this monocentric retrospective study, which included 106 patients who had not been previously treated with anti-cancer agents, we evaluated the efficacy and safety of oral alkylating agents monotherapy (n = 48), rituximab monotherapy (n = 28) and the therapy combining both drugs (n = 30). Evaluations were performed at weeks 6 (W6), 25 (W25), and 52 (W52) and after 2 years (W104). After a median follow-up period of 4.9 years (range 0.4-17.2 years), complete remission and overall response were significantly higher in patients in the combination therapy group at W104 (92% and 100% respectively) compared with patients treated with alkylating agents alone (66% and 68%) and rituximab alone (64% and 73%). The 5-year progression-free survival probabilities were 68%, 70% and 89% in patients treated with alkylating agents alone, rituximab alone and combination therapy respectively. Haematological adverse events were reported in 32 (30%) patients (mostly grade 1) and were more frequent in the two groups receiving alkylating agents (P = 0.05 and P alkylating agents alone. Rituximab has a better safety profile than regimens containing alkylating agents. © 2014 John Wiley & Sons Ltd.

    constraints. One the most popular form of congestion pricing is cordon charging where inbound commuters are charged a certain fixed fee. The efficiency of cordon pricing has been explored by numerous empirical and simulation studies. However, theoretical explanations of results are largely missing. I consider a monocentric city model to explore the effect of cordon charging schemes on urban density and housing demand (equilibrium rent. Cordon pricing increases rents at the center and also the slope of the bid-rent curve. Most importantly, these quantities are functions of cordon parameters which suggest that efficiency is affected by planners’ choice of cordon parameters.Keywords.

    The condylar region is a frequent localization of mandibular fractures; there are various types of management. Mini-invasive endoscopic surgery is an alternative to open reduction. We had as goal to evaluate the outcome of this technique. We performed a monocentric retrospective study of patients consecutively operated for a condylar fracture (type II to V in the Spiessl and Schroll classification) with intraoral route and endoscopic assistance, during 30 months. We assessed the functional and radiological outcomes, and the complications. Twenty-two patients (25 fractures) were included. Seventeen patients (19 fractures) could be followed (mean follow-up: 16.7 months). The mean values were: interincisal opening, 45mm (±8.4); protrusion, 8.3mm (±1.9); ipsilateral excursion of the jaw: 8.6mm (±2); contralateral excursion: 8.7mm (±4). Three routes were used combined with a preauricular approach. The fracture reduction was good for 10 of the 19 fractures and poor for 3. The complications were: 3 cases of infection, 1 case of fixation failure with good consolidation; for combined approaches: 2 cases of temporary facial palsy and 2 cases of Frey syndrome. Endoscopic assistance for the surgical management of the fracture of mandibular condyle is a reliable technique, with a good functional outcome, and a low rate of specific complications, especially for facial nerve lesion or esthetic outcome.

    The recent sociopolitical events in the Mediterranean and Middle Eastern areas have significantly impacted international migration flows. As disease prevalence and type are different among western and Afro-Asian countries, physicians dealing with refugees should be aware of their specific health needs. We aimed at evaluating the health status and disease history of refugees at their arrival in the urban area of L'Aquila (Italy). This is a monocentric cross-sectional study. Refugees hosted at the local reception center in L'Aquila (Italy) between July 2014 and December 2014 were cross-sectionally evaluated for anamnestic, clinical, and laboratory features. A subset of randomly selected participants underwent further assessments (screening for tuberculosis, hepatitis B/C, human immunodeficiency virus, syphilis; ambulatory blood pressure measurement [ABPM]) to better define their health status. Ninety-three adult male refugees (27.34 ± 7.41 years) from Africa (76%) and Asia (24%) were enrolled. Overall, the most prevalent diseases according to the International Statistical Classification of Diseases and Related Health Problems 10th revision affected the digestive tract (15.6%) and musculoskeletal apparatus (14.4%). The analysis by continent of origin did not show significant differences in the distribution of diseases, although a trend toward some differences was observed. African refugees had a significantly greater prevalence of viral hepatitis (hepatitis B virus, P = 0.004; hepatitis C virus, P = 0.007) compared with Asians. Hypertension, as detected by ABPM, was uncommon. No written vaccination history was available. Health issues of our sample of Afro-Asian refugees span both non-communicable and communicable diseases, requiring attention for the safety of the individual and the community. National health systems should provide adequate information and shared guidelines for health professionals regarding identification and management of refugees' health

A prospective, monocentric, uncontrolled study was conducted between January 2012 and March 2015 on 110 eyes of 55 patients with severe dry eye on first line therapy or previously treated with Restasis ® who required the introduction of Ikervis ® . Patients' quality of life was assessed before and after treatment was started using a standardized questionnaire (Ocular Surface Disease Index © [OSDI]), clinical efficacy was quantified at the slit lamp, by measurement of the Break Up time Test (BUT) and the Oxford classification. Tolerability and adherence to treatment were measured using a simple questionnaire. A total of 72 eyes of 37 patients were included. Etiologies of dry eye syndrome were dominated by Sjögren syndrome (32 %) and severe ocular surface conditions (48 %). The mean age was 57.7 years (±17.45) and mean follow-up was 458 days (±292). The mean BUT increased by 2.043seconds [1.522-2.563] (Pdry eye. Its indications tend to evolve towards less severe dry eye. However, the tolerability profile remains poor, and an improvement in this would be desirable. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Full Text Available Objectives: We retrospectively reviewed data of patients with incidental prostate cancer (PCa who underwent radical cystoprostatectomy (RCP for invasive bladder cancer and we analyzed their features with regard to incidence, pathologic characteristics, clinical significance, and implications for management. Material and Methods: Clinical data and pathological features of 64 patients who underwent standard RCP for bladder cancer were included in this study. Besides the urothelial carcinoma of the urinary bladder, the location and tumor volume of the PCa, prostate apex involvement, Gleason score, pathological staging and surgical margins were evaluated. Clinically significant PCa was defined as a tumor with a Gleason 4 or 5 pattern, stage ≥ pT3, lymph node involvement, positive surgical margin or multifocality of three or more lesions. Postoperative follow-up was scheduled every 3 months in the first year, every 6 months in the second and third year, annually thereafter. Results: 11 out of 64 patients (17.2% who underwent RCP had incidentally diagnosed PCa. 3 cases (27.3% were diagnosed as significant PCa, while 8 cases (72.7% were clinically insignificant. The positive surgical margin of PCa was detected in 1 patient with significant disease. The prostate apex involvement was present in 1 patient of the significant PCa group. Median follow-up period was 47.8 ± 29.2 (range 4-79. During the follow-up, biochemical recurrence occurred in 1 patient (9%. Concernig the cancer specific survival there was no statistical significance (P = 0.326 between the clinically significant and clinical insignificant cancer group. Conclusions: In line with published studies, incidental PCa does not impact on the prognosis of bladder cancer of patients undergoing RCP.

    Although most infections occur within the first 2 years after splenectomy, the relatively short follow-up reported in many studies may underestimate the frequency of infections. The objective of the study was to determine the incidence of infective outcomes and factors associated with infection after splenectomy by studying a group of patients who underwent splenectomy over a 10-year period. A retrospective and monocentric study of patients who underwent splenectomy between January 1st, 1997 and December 31st, 2004 in a French university hospital. Age, sex, indication for splenectomy, infectious events, death, vaccination and antibiotic prophylaxis were collected in January 2015. One hundred and sixty-five patients were included. The most common reasons for splenectomy were therapeutic hematological indications (37.5%). Ninety-seven per cent received pneumococcal vaccine. Prophylactic antibiotics were prescribed in 78% of patients. Thirty-seven patients had 42 severe infections with a median incidence rate of 4 years after splenectomy (2 days-12 years). The rate of infection after splenectomy declined over time but 57% occurred after 2 years and 14.3% after 10 years. Respiratory infections were the most common sites of infections. The incidence of infection differed according to age was highest among the elderly (HR=6.2; 95%CI: 1.4-27.1; after 65 years old) and underlying reason for splenectomy (P=0.02). There is no difference with or without prophylactic antibiotics. After splenectomy, the incidence of severe infection declined over time but can occur after 10 years. The onset of infection is linked to age and reason for splenectomy. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

    With the development of related technology gradually mature in the field of optoelectronic information, it is a great demand to design an optical system with high resolution and wide field of view(FOV). However, as it is illustrated in conventional Applied Optics, there is a contradiction between these two characteristics. Namely, the FOV and imaging resolution are limited by each other. Here, based on the study of typical wide-FOV optical system design, we propose the monocentric multi-scale system design method to solve this problem. Consisting of a concentric spherical lens and a series of micro-lens array, this system has effective improvement on its imaging quality. As an example, we designed a typical imaging system, which has a focal length of 35mm and a instantaneous field angle of 14.7", as well as the FOV set to be 120°. By analyzing the imaging quality, we demonstrate that in different FOV, all the values of MTF at 200lp/mm are higher than 0.4 when the sampling frequency of the Nyquist is 200lp/mm, which shows a good accordance with our design.

    Full Text Available The aim of this study was to correlate placental volumes deduced from three-dimensional ultrasound and virtual organ computer-aided analysis (VOCAL software with systemic concentrations of D-dimer and soluble endothelial protein C receptor (sEPCR.This was a monocentric experimental prospective study conducted from October 2008 to July 2009. Forty consecutive patients at risk of placental vascular pathology (PVP recurrence or occurrence were included. Placental volumes were systematically measured three times (11-14, 16-18 and 20-22 weeks of gestation (WG by two independent sonographers. D-dimers and sEPCR plasma concentrations were measured using ELISA kits (Enzyme Linked ImmunoSorbent Assay.Eleven patients had a PVP. The plasma D-dimer level was positively correlated with placental volume (r = 0.45, p < 0.001. A smaller placental volume and placental quotient was evidenced in women who developed a PVP at the three gestational ages, and the difference was more pronounced during the third exam (20 WG. No obvious correlation could be demonstrated between the development of a PVP and the levels of D-dimer and sEPCR. There was no significant difference in the values of placental volumes measured by the two sonographers.The placenta growth could be a major determinant of the elevation of D-dimer during pregnancy. Consideration of placental volume could allow for modulation of the D-dimer concentrations for restoring their clinical interest.

    To study the prevalence of different causes of hypertension in young adults referred to a hypertension center in the south west of France. We conducted a retrospective overview of patients younger than 40years old hospitalized consecutively in the Hypertension department of Toulouse University Hospital between 2012 and 2014. Clinical data about gender, age, anthropomorphic parameters and blood pressure measurement by 24h Ambulatory Blood Pressure Monitoring (ABPM) were recorded. Biological data concerned dosages of kalemia, renin and aldosterone in the supine or after 15min of seating. Recorded radiological examinations were renal artery ultrasound and abdominal CT scan. One hundred and forty-eight detailed medical records were analyzed, 69 women and 79 men. Among the 69 women, the causes of secondary hypertension were primary aldosteronism (n=7), fibromuscular dysplasia (n=5) and renal disease (n=4). Oral contraceptives were involved in 13 women. In addition, essential hypertension concerned 40 women (58%). Among the 79 men, the causes of secondary hypertension were primary aldosteronism (n=10), fibromuscular dysplasia (n=3), left main renal artery entrapment by a diaphragmatic crura (n=2), renal disease (n=1), pheochromocytoma (n=3) and coarctation of the aorta (n=2). In addition, essential hypertension concerned 58 men (73%). In our population, the prevalence of secondary hypertension is close to 33% (42% of females and 27% of males), with the following main causes: primary aldosteronism for 11.5%; fibromuscular dysplasia for 5.4%. Oral contraceptives were involved in the hypertension of 19% of the females. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    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.

    The aim of this prospective study was to evaluate clinical and radiographic results in the patients who underwent L5-S1 fixation using the technique of percutaneous lumbar interbody fusion (AxiaLIF). The study comprised 23 patients, 11 women and 12 men, who ranged from age of 21 to 63 years, with an average of 48.2 years. In all patients surgical posterior stabilisation involving the L5-S1 segment had previously been done. The initial indications for surgery were L5-S1 spondylolisthesis in 20 and L5-S1 spondylosis and stenosis in three patients. The AxiaLIF technique for L5-S1 fixation was indicated in overweight patients and in those after repeated abdominal or retroperitoneal surgery. A suitable position and shape of the sacrum or lumbosacral junction was another criterion. The patients were evaluated between 26 and 56 months (average, 40.4 months) after primary surgery and, on the basis of CT and radiographic findings, bone union and lumbosacral junction stability were assessed. The clinical outcome was investigated using the ODI and VAS systems and the results were statistically analysed by the Wilcoxon test for paired samples with statistical significance set at a level of 0.05. The average VAS value was 6.6 before surgery and, after surgery, 5.2 at three months, 4.2 at six months, 3.1 at one year, 2.9 at two years and 2.1 at three years (n=18). At two post-operative years, improvement in the VAS value by 56.1% was recorded. The average pre-operative ODI value was 25.1; the post-operative values were 17.0 at six months, 12.3 at one year, 10.6 at two years and 8.2 at three years (n=18). At two years after surgery the ODI value improved by 57.8%. To the question concerning their willingness to undergo, with acquired experience, surgery for the same diagnosis, 21 patients (91.3%) gave an affirmative answer. Neither screw breakage nor neurovascular damage or rectal injury was found. CT scans showed complete interbody bone fusion in 22 of the 23 patients (95

    Accessibility to innovative multiple myeloma therapies is limited in sub-Saharan Africa. This study aimed to describe the diagnostic and evolutionary features observed during treatment of our patients with myeloma. We conducted a retrospective, descriptive, analytical study (2005 - 2016) of patients with myeloma included in the study based on International Myeloma Working Group (IMWG) Criteria (2003,2014) at the Hopital Aristide Le Dantec (Senegal). We collected data from 136 medical records (69 men, 67 women) of patients with an average age of 59 years ± 10.1 years, who were less than 65 years of age in 69.1% of cases. Tell-tale signs included bone pain (96.3%), renal failure (36.8%), infection (23.5%), pathological fracture (17.6%), spinal cord compression (16.9%) and malignant hypercalcaemia (16.2%). Isotopic antiglobulin test showed that anti-IgG could be detected in 61.3% of cases and Kappa in 65% of cases. Patients were classified stage III (59.4%) and I-II (40.6%)of the index staging system. The median survival of patients under conventional traitement (Méphalan-Prédnisone: 67.6%, innovative: 5.9%) was 20 months (1-78 months). Survival rates are better in the absence of neurological and infectious complications and for patients with score I-II of the index Staging System. In our study, multiple myeloma was frequently diagnosed before age 65, at advanced stage of tumor mass. Early detection and access to adequate therapies could improve overall survival.

    Soluble Fms-like tyrosine kinase 1 (sFlt-1) is an anti-angiogenic factor released in higher amounts in preeclampsia and implicated in endothelial dysfunction. sFlt-1/PlGF ratio is used in the prediction of preeclampsia. An sFlt-1/PlGF ratio inferior to 38 predicts the short-term absence of preeclampsia. A ratio ? 85 (early-onset PE) or ? 110 (late-onset of PE) could diagnose preeclampsia. In this study, sFlt-1/PlGF ratio has been measured in 183 patients. Sixty-seven preeclampsia have been diagnosed preeclamptic at delivery. The median sFlt-1/PlGF ratio was 100.3. The median ratio among women with preeclampsia (N=67) versus no preeclampsia (N=116) was 212.7 versus 35.4. In accordance with this analysis, an sFlt-1/PlGF ratio ? 38 has a sensibility of 95,5 % and a specificity of 73.3 %. The positive predictive value and the negative predictive value were 67.4 % and 96.6 %, respectively. These results suggest that sFlt-1/PlGF ratio is helpful in the diagnosis of preeclampsia.

    2005-12-01

    This study investigated the amounts of problem-solving process information ("action," "why," "how," and "metacognitive") elicited by means of concurrent, retrospective, and cued retrospective reporting. In a within-participants design, 26 participants completed electrical circuit troubleshooting tasks under different reporting conditions. The method of cued retrospective reporting used the original computer-based task and a superimposed record of the participant's eye fixations and mouse-keyboard operations as a cue for retrospection. Cued retrospective reporting (with the exception of why information) and concurrent reporting (with the exception of metacognitive information) resulted in a higher number of codes on the different types of information than did retrospective reporting.

    Full Text Available In this study, our aim was to evaluate the antibiotic susceptibility of bacteria isolated from orthopedic implant infections. Within two years operated 1996 patients in an orthopedics and traumatology clinic were retrospectively investigated. Seventy-six (76/1996, 3.8% orthopedic implant infections were detected. Isolated bacteria and their antibiotic susceptibility patterns were analyzed. The bacteries isolated from implant related infections and antibiotic sensitivity patterns were evaluated retrospectively in our orthopaedics and traumatology clinic. Staphylococcus aureus was the predominant organism (30.3%. Gram negative bacterias were isolated in 65.8% of our patients. No resistance was determined against vancomycin and linezolid in gram positive bacterias. Imipenem, amicasin and cefepim was seen as the most effective antibiotics for gram negative bacterias.

    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.

    This study was driven forward centering around physical techniques in retrospective dosimetry system for encountering nuclear radiation accident. The results obtained through this study are summarized as follow : the minimal facilities based on physical techniques should be assured at KINS for appropriate operation and establishment of retrospective accident dosimetry system, the necessary apparatus and man power for retrospective dose assessment by physical techniques might be operated flexibly, however, CL and TL/OSL readers should be equipped with the highest priority, a series of comparative examination of several physical techniques for retrospective dose assessment revealed that most of the irradiated materials around accident sites are usable for the dose assessment, if a priori study on the dosimetrical characteristics of those materials is preceded in accordance with the species of the collectable samples, the results of the study on the CL-dose response and radiation energy dependence of sugar and sorbitol, showed the nonlinearity in CL-dose relationship at the range of low dose(less than 5 Gy), and it led us to perform a study on the correction of the nonlinearity, and in the later study, CL output showed heavy dependence on radiation energy in the energy below around 100 keV and accordingly, a study on the correction for the energy dependence was also carried out, ve were able to obtain good results as a first attempt to carry out such corrections.

    Anemia is very commonly seen in most of the malignancies including cancer cervix. Anemia has long been reported to adversely affect the efficacy of radiation treatment in cervical cancer. At our center, carcinoma cervix accounts for approximately 8-10% of all malignancies. The objective of this study is to see the impact of anemia in the treatment of cancer cervix. In the present study, we collected data of treatment results of FIGO stage II and III cancer cervix patients retrospectively treated in years of 2009-10. We have tried to assess the outcome of results in patients whom haemoglobin (Hb) level < 10 gm/dl and e''10 gm/dl. Out of 200 patients of disease with baseline Hb less than 10 gm/dl, 80(40%) patients had residual disease after 4 weeks of completion of treatment. Out of 168 patients with baseline Hb more than 10 gm/dl, 42(25%) had residual disease (p-0.0012 i.e highly significant). Our study shows that there is a good disease control at local site in patients with higher pretreatment Hb level. Effect of pretreatment Hb on treatment outcome in terms of overall survival, disease free survival, and local relapse free survival along with effect on corrective measures should be studied in detail.

    There are few data on long-term clinical results and tolerance of brachytherapy in anal canal cancer. We present one of the largest retrospective analyses of anal canal cancers treated with external beam radiotherapy with/without (±) chemotherapy followed by a brachytherapy boost. We performed a retrospective analysis of clinical results in terms of efficacy and toxicity. The impact of different clinical and therapeutic variables on these outcomes was studied. From May 1992 to December 2009, 209 patients received brachytherapy after external beam radiotherapy ± chemotherapy. Of these patients, 163 were stage II or stage IIIA (UICC 2002) and 58 were N1-3. According to age, ECOG performance status (PS), and comorbidities, patients received either radiotherapy alone (58/209) or radiochemotherapy (151/209). The median follow-up was 72.8 months. The 5- and 10-year local control rates were 78.6 and 73.9 %, respectively. Globally, severe acute and late G3-4 reactions (NCI-CTC scale v. 4.0) occurred in 11.2 and 6.3 % of patients, respectively. Univariate analysis showed the statistical impact of the pelvic treatment volume (p = 0.046) and of the total dose (p = 0.02) on the risk of severe acute and late toxicities, respectively. Only six patients required permanent colostomy because of severe late anorectal toxicities. After a long follow-up time, brachytherapy showed an acceptable toxicity profile and high local control rates in patients with anal canal cancer. (orig.)

    Sperm banking is an important procedure to preserve fertility before cancer therapy. The aim of this study was to comprehensively analyse cryopreservation activity retrospectively for 1080 patients referred to the sperm bank for sperm cryopreservation before cancer treatment. This study included 1007 patients diagnosed with testicular cancer (TC) (41.7%), lymphoma (26%), other haematological cancers (9.4%) or other types of cancer (22.8%); of these, 29 patients did not produce any semen sample and cryopreservation was impossible for 67 patients. Semen characteristics before treatment were within normal ranges, except moderate asthenospermia. Sperm concentration was significantly lower in TC than in non-TC. Straws from 57 patients (6.3%) were used in assisted reproductive technologies, which led to a 46.8% cumulative birth rate. Straws were destroyed for 170 patients (18.7%) and 140 patients performed semen analyses after cancer therapy. After an average delay of 22.5 months after the end of therapy, 43 patients (30.7%) exhibited azoospermia. This study of a large population of cancer patients revealed a high level of successful sperm storage. Utilization of cryopreserved spermatozoa led to good chances of fatherhood. Nevertheless, sperm banks should be aware of the low rates of straw use and straw destruction by cancer patients. Copyright © 2011 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

    Although opinions preferring individual administration of activity in the treatment of thyroid cancer with 131 I predominate, sufficient quantitative arguments in favor of this approach are unavailable as yet. Therefore, a retrospective study involving statistical processing was proposed with the aim to evaluate the relations between available data of the patients and success of treatment. Ideally, recommendations regarding activity to be administered in dependence on the biophysical status of the patient should emerge from the study

    Full Text Available Introduction. The aim of this study was to assess the complications resulting from third molar extraction under general anesthesia. Material and Methods. The retrospective study included all patients who underwent impacted third molars extraction from January 2008 until December 2011. 7659 third molars were extracted for 2112 patients. Postoperative complications were retrieved from medical files. Results. No complications were related to general anesthesia. The most frequent postoperative complication was infection (7.15%. Lingual nerve injuries affected 1.8% of the patients. All of them were transient and were not related to tooth section. Inferior alveolar nerve injuries were reported in 0.4% of the cases. 95.8% of these patients were admitted for one-day ambulatory care, and only two patients were readmitted after discharge from hospital. Discussion. This surgical technique offers comfort for both surgeons and patients. Risks are only linked to the surgical procedure as we observed no complication resulting from general anesthesia. One-day hospitalization offers a good balance between comfort, security, and cost. The incidence of complications is in agreement with the literature data, especially regarding pain, edema, and infectious and nervous complications. It is of utmost importance to discuss indications with patients, and to provide them with clear information.

    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.

    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. Author responses supported these findings. The high proportion of mapped data elements demonstrates the significant potential for clinical data warehousing to facilitate clinical research. Unmapped data elements illustrate the difficulty in developing a complete data dictionary. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

A retrospective analysis of 62 patients treated with concomitant radio-chemotherapy for inoperable stage III NSCLC has been carried out in the Department of Pneumology (University Hospital of Nancy). The patients were divided into 2 groups according to the chemotherapy protocol, group 1: Cisplatin-etoposide (27 patients) and group 2: Carboplatin-Paclitaxel (35 patients). The two groups were comparable in terms of age and gender (mean age 58 in group 1 versus age 61 in group 2, and 85 pc of men in group 1 versus 80 pc in group 2). The median overall survival was 19 months in group 1 versus 15.3 months in group 2 (p = 0.22). The median progression-free survival was higher in group 1, 9 months versus 3.3 months in group 2 (p = 0.01). Hematologic toxicity was higher in group 1 than in group 2 (neutropenia 85.2 pc versus 54.3 pc, p = 0.01, anemia 92.3 pc versus 54.3 pc, p = 0.001). Radiation esophagitis and radiation pneumonitis rates were higher in group 1 than in group 2: 44.4 pc versus 11.4 pc (p = 0.01), and 44.4 pc versus 11.4 pc (p = 0.001) respectively. In this mono-centric and retrospective study, the Cisplatin-etoposide - thoracic radiotherapy combination to treat inoperable stage III NSCLC was associated with a significantly higher progression-free survival than the Carboplatin-Paclitaxel-radiotherapy combination. This increase in survival was accompanied by a significantly higher hematological and organ toxicity [fr

    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.

    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.

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

    Directory of Open Access Journals (Sweden)

    Simon Tobin

    Full Text Available 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.

    A retrospective study was conducted to determine the importance of the interval between diagnosis of brain metastasis (BRM) and cranial irradiation (CI). The charts of 92 patients with a known diagnosis of cancer and suspected BRM as shown on radioimaging studies were reviewed retrospectively. The median interval between diagnosis and the onset of CI for BRM was five days; one group of 48 individuals received CI within an interval of five days, and another group of 44 patients after an interval of five days. Symptom palliation, objective responses to CI and survival were evaluated in both groups. Neither symptomatic and objective responses to treatment nor overall survival differed significantly between the patient groups. These observations suggest that while CI is beneficial to most patients with BRM, its timing after the diagnosis of BRM may not seriously affect patient outcome. (author)

    An apparent increased risk for developing Amyotrophic Lateral Sclerosis (ALS), a multifactorial neurodegenerative disease, is considered to exist in the military population. ALS military and veteran patients were retrospectively recruited in April 2008 by searching medical data (Hippocrate) and repayment data (Erasme) of the French National Military Health Care Fund (Caisse nationale militaire de sécurité sociale, CNMSS) from de January 1991 to December 2007. We report a series of 73 patients, 69 male and four female, average age of 52.5 years (range 27 to 72 years) with a peak of patients in the 50-59 year age class. The branch of military service was Army (n=26 patients), Air force (n=14), Navy (n=10) and State Police Force (n=22). The incidence among male active duty military personnel was stable from 2002 to 2007; it was less than the general population (1.7/100,000 per year in 2007), but higher in the 40-44 and 50-54 year age classes (1.90 and 5.07/100,000 per year in 2007 respectively). Duration of active duty was on average 31 years. The retrospective nature of the data and the incomplete population with loss of retired military personnel without CNMSS affiliation are limitations of our study. Another means of collecting all cases of ALS among French military personnel and veterans would be to conduct a search in the 17 ALS centers in France with analysis by occupational activity for entire career.

    Full Text Available Objective: A retrospective study detailing the circumstances surrounding diagnosis and treatment of pheochromocytomas with the associated genetic disorders. Materials and Methods: All patients with surgically excised pheochromocytomas in the Health Sciences Center, St. John′s, Newfoundland, Canada between January 2001 and December 2010 were retrospectively analyzed to determine associated familial syndromes, age, tumor size, symptomatology, and percentage of paragangliomas and bilateral pheochromocytomas. Pathology specimen reports, adrenalectomy lists and Meditech (electronic medical record diagnostic codes provided a comprehensive database for this study. Results: Twenty-four patients were studied; familial disorder patients comprised 42% (10/24. Average age at diagnosis was 57 among the sporadic and 34 in familial disorder groups (P = 0.006. Average tumor size was 4.5 cm in the sporadic group and 3 cm in the familial disorder group (P = 0.19. All atypical cases including bilateral or extra-adrenal tumors and malignancy occurred in familial disorder patients. Conclusions: The proportion of familial disorder patients (42% was higher in this study than would be expected, likely a result of the relatively high incidence of hereditary autosomal dominant disorders within Newfoundland. Among familial disorder patients, the average younger age at diagnosis and the smaller tumor size suggest syndromic pheochromocytomas may develop earlier, however they are more likely to be diagnosed sooner due to biochemical surveillance testing in known genetic disorder patients. We also demonstrate a relatively high incidence of surgically resected pheochromocytomas of 4.679/million/year in Newfoundland.

    This Objective of this study was to see histologic typing of prostate cancer and its relation to patient's age, as no curative therapy exists for the advanced stages. This is a retrospective study of 50 patients suffering from prostatic adenocarcinoma and admitted at Basic Medical Sciences Institute, Jinnah Postgraduate Medical Center Karachi. A total of fifty patients between ages of 50-80 years diagnosed during the period of 1990-2001 suffering from prostate cancer were included in this study. The result showed that maximum number of tumours were in age group ranging from 61-70 years, (58% of total cases). Sixteen were (32%) well-differentiated tumours, twenty-eight (56%), moderately differentiated tumours and six (12%) were labelled as undifferentiated tumours. It was concluded that the majority of tumors were moderately differentiated tumours. Early diagnosis is useful for patients; because high grade tumours have bad prognostic markers. (author)

    Full Text Available BACKGROUND Oesophageal cancer is a serious malignancy with regards to mortality and prognosis. It is a growing health concern that is expected to increase in incidence over the next 10 years. Squamous cell carcinoma is the most common histological type of oesophageal cancer worldwide with a higher incidence in developing nations. With the increased prevalence of gastroesophageal reflux disease and obesity in developed nations, the incidence of oesophageal adenocarcinoma has dramatically increased in the past 40 years. MATERIALS AND METHODS Retrospective study was conducted to study the clinical profile of patients presented with oesophageal carcinoma at Government Medical College, Kottayam, Kerala, India, during January 1, 2015, to December 31, 2016. 104 subjects who met the inclusion criteria were enrolled. Data were collected from the records. RESULTS Out of 104 subjects enrolled in the study, 78 (75% were males, rest 26 (25% were females. 73% of the patients with oesophageal carcinoma were above 60 years. 79.8% patients presented with dysphagia. 87.5% cases had squamous cell type lesions. More than 75% of the lesions were in the mid and lower oesophagus. Noduloulcerative type was the most common morphologic presentation. CONCLUSION Squamous cell carcinoma is the most common oesophageal carcinoma in our institution. Majority of the lesions are located in the mid and lower oesophagus and are well differentiated.

    Clinical cohort study. To evaluate if the impact of the severity of the trauma as a possible confounding factor influences the neurological and functional recovery in paraplegia during the course of a 6-month follow-up period after injury. Spinal Cord Injury Center, Heidelberg University Hospital, Germany. A retrospective monocentric analysis, from 2002 to 2008, of the Heidelberg European Multicenter Study about spinal cord injury database was performed. We included 31 paraplegic patients (neurological level T1-T12) who were assigned either to a monotrauma (polytraumaschluessel (PTS) 1) or to a polytrauma (PTS≥2) group. The American Spinal Injury Association Impairment Scale, lower extremity motor score, pin prick, light touch and the spinal cord independence measure (SCIM) were obtained at five distinct time points after trauma. Data were analyzed using Mann-Whitney U-test (αpressure sores between 3 and 6 months (P=0.031). The mean length of primary rehabilitation in the polytrauma group was 5.5 vs 3.6 months in monotrauma. The prognosis of polytraumatic paraplegics in terms of neurological recovery is not inferior to those with monotrauma. Multiple-injured patients need a prolonged hospital stay to reach the functional outcome of monotraumatic patients.

    In this paper we sought to reproduce, as a computational retrospective study in an EHR database (MIMIC-II), a recent large prospective clinical study: the 2013 publication, by the Japanese Association for Acute Medicine (JAAM), about disseminated intravascular coagulation, in the journal Critical Care (PMID: 23787004). We designed in SQL and Java a set of electronic phenotypes that reproduced the study's data sampling, and used R to perform the same statistical inference procedures. All produced source code is available online at https://github.com/fabkury/paamia2015. Our program identified 2,257 eligible patients in MIMIC-II, and the results remarkably agreed with the prospective study. A minority of the needed data elements was not found in MIMIC-II, and statistically significant inferences were possible in the majority of the cases.

    2015-09-01

    Full Text Available Background: 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. Methods: 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. Results: 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 ± 140.9 mg. There was no correlation between the mean caffeine consumption and exacerbations (p > 0.05. Discussion: 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. Keywords: COPD, Caffeine, Disease exacerbation, Purines, Pharmacology, Coffee, Respiratory Tract Diseases

  3. Accuracy of glenoid component placement in total shoulder arthroplasty and its effect on clinical and radiological outcome in a retrospective, longitudinal, monocentric open study.

    Directory of Open Access Journals (Sweden)

    Thomas M Gregory

    Full Text Available BACKGROUND: The success of Total Shoulder Arthroplasty (TSA is believed to depend on the restoration of the natural anatomy of the joint and a key development has been the introduction of modular humeral components to more accurately restore the patient's anatomy. However, there are no peer-reviewed studies that have reported the degree of glenoid component mal-position achieved in clinical practice and the clinical outcome of such mal-position. The main purpose of this study was to assess the accuracy of glenoid implant positioning during TSA and to relate it to the radiological (occurrence of radiolucent lines and osteolysis on CT and clinical outcomes. METHODS: 68 TSAs were assessed with a mean follow-up of 38+/-27 months. The clinical evaluation consisted of measuring the mobility as well as of the Constant Score. The radiological evaluation was performed on CT-scans in which metal artefacts had been eliminated. From the CT-scans radiolucent lines and osteolysis were assessed. The positions of the glenoid and humeral components were also measured from the CT scans. RESULTS: Four position glenoid component parameters were calculated The posterior version (6°±12°; mean ± SD, the superior tilt (12°±17°, the rotation of the implant relative to the scapular plane (3°±14° and the off-set distance of the centre of the glenoid implant from the scapular plane (6±4 mm. An inferiorly inclined implant was found to be associated with higher levels of radiolucent lines while retroversion and non-neutral rotation were associated with a reduced range of motion. CONCLUSION: this study demonstrates that glenoid implants of anatomic TSA are poorly positioned and that this malposition has a direct effect on the clinical and radiological outcome. Thus, further developments in glenoid implantation techniques are required to enable the surgeon to achieve a desired implant position and outcome.

    Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

    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

    2003-01-01

    Electron Spin Resonance (ESR) spectroscopy is one of the methods applicable to retrospective dosimetry. The retrospective dosimetry is a part of dose reconstruction for estimation of exposed dose occurred years before the estimation. A tooth can be separated as enamel, dentine and cementum. Among the three parts, enamel is known as to show the best sensitivity to the absorbed dose and is most widely used. Since the later 80s, ESR dosimetry with tooth enamel has been studied and applied for the retrospective dosimetry. There are some factors affecting the sensitivity of enamel to absorbed dose. One of the factors is a size of enamel. Grain size of the 1.0mm∼0.1mm range is commonly used and 0.6mm∼0.25mm is recommended in other study. But the sensitivity can be varied by the grain size. In this study, the granular effect of enamel to the sensitivity is examined for application to retrospective dosimetry. In the enamel separation, to minimize the physically induced ESR spectrum, only chemical separation method was used. Separated enamels were divided by their size. The sizes of each sample is 1.0mm∼0.71mm, 0.5mm∼0.3mm, and below 0.1mm, respectively. All enamel samples show ESR spectrum related to the absorbed dose and the ESR spectrum shows linearity to the absorbed dose. The sensitivities are similar for each sample. But the enamel of size below 0.1mm shows poor characteristics relative to other enamel size. So, it is not recommended to use enamel samples below 0.1mm

    Objectives To examine by retrospective analysis of data from the FLEXI‐CUT monocentre registry whether atherectomy can effectively simplify complex stent implantation in ostial bifurcation lesions by reducing the procedure to stenting of the left anterior descending (LAD) or left circumflex (LCX) artery ostium alone. Patients and methods All patients who had been enrolled in the prospective FLEXI‐CUT study (directional atherectomy with adjunctive balloon angioplasty) were retrospectively analysed on the basis of significant LAD or LCX ostial stenosis (⩾ 70% stenosis) deriving from an undiseased left main stem. The primary combined end point was the rate of target lesion revascularisation (TLR) and binary restenosis; secondary end points were procedural success and major adverse cardiac events (MACE) at the six‐month follow up. Results Of 30 patients enrolled with significant LAD or LCX ostium stenosis, 29 were effectively treated with directional atherectomy (96.7% procedural success). All patients underwent single‐vessel stenting procedures of solely the LAD or LCX ostium. At follow up, binary stenosis was 25% (6 of 24), TLR (angiographic plus clinical) 10.3% (3 of 29) and total MACE 6.9% (2 of 29). Conclusions Directional atherectomy with single‐vessel stenting procedures facilitates the interventional treatment of LAD and LCX ostium stenosis, and leads to remarkably low TLR and binary stenosis at follow up.

    To describe the increased incidence of sexually transmitted infections (STIs) in a cohort of HIV-infected men who have sex with men (MSM), followed in a tertiary hospital of the Île-de-France region. We performed a monocentric, retrospective, and prospective study. We included symptomatic HIV-infected MSM patients who consulted for their annual consultation. One hundred and eighty patients were seen between 2008-2011 and 215 between 2012-2015. We observed an increased incidence of STIs between the two periods (14 and 29.3%, respectively). These STIs includes: syphilis, hepatitis C, urethritis, and proctitis due to Chlamydia trachomatis and Neisseria gonorrhea. A better management of symptomatic and asymptomatic STIs is needed for HIV-infected MSM patients. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

  11. Impact of the cosmetic mouthwash “Jack Pro Spülung plus” (“rheodol-Spülung plus” on the oral cavity flora, tested in a monocentric, controlled, randomized, blind, cross-over comparative study

    2014-03-01

    Full Text Available [english] Aim: Jack Pro Spülung Plus (also available as “rheodol-Spülung plus” is recommended to mechanically maintain oral hygiene as part of an overall oral hygiene concept. Because Jack Pro Spülung Plus contains the active agents polihexanide and tosylchloramide sodium in concentrations below microbicidal efficacy, this study tested the hypothesis that the combination of mechanical rinsing and bacteriostatic effect surpasses the effect of mechanical rinsing alone.Method: The study was performed with 30 volunteers as a monocentric, controlled, randomized, blind, cross-over comparative study. The efficacy of the test product (active agents polihexanide 0.02–0.03% and tosylchloramide sodium 0.004–0.006% was compared to an aqueous solution of polihexanide (0.02–0.03% and to Ringer solution as negative control. The efficacy was measured as the reduction of colony forming units (cfu on buccal mucosa after aerobic and anaerobic cultivation. After determination of pre-values, the volunteers performed mouthrinsing for 30 sec with each of the 3 tested solutions. After 1, 10 and 60 minutes, cfu numbers were determined again. The reduction factor was calculated as the difference between log of the measured cfu before and after mouthrinsing with the test solution. The sampling was performed using a template with a smear area of 1 x 1 cm. Results: Using Ringer solution led to a slight mechanically-induced reduction of cfu in the oral cavity 1 min after rinsing the mouth cavity with the solution. After 10 min and 60 min, no influence on the cfu number could be detected. Using Jack pro Spülung Plus led to a bacteriostatic effect up to 60 min after mouthrinsing; 10 min and 60 min after rinsing the efficacy of Ringer solution was also significantly surpassed. The aqueous solution of polihexanide was less effective than Jack pro Spülung Plus after 10 and 60 min. Conclusion: Based on these observations, we conclude that Jack pro Spülung Plus is

    Full Text Available Context: A variety of nonvenereal diseases can affect the penis and diminish quality of life. Many present similar clinical features and a cutaneous biopsy may be necessary to clarify the diagnosis. Aims: To characterize nonvenereal penile dermatoses with histological confirmation in a southwestern Europe hospital during a 9-year period. Materials and Methods: A retrospective study was conducted. We reviewed all penile biopsies performed between January 1, 2007 and December 31, 2015 and studied the causes of the nonvenereal penile dermatoses. Results: The sample included a total of 108 patients, aged 62.9 (±17.8 years, between 16 years and 96 years of age. Eighteen dermatoses were identified. Inflammatory diseases were present in 65. 7% of patients (71/108 and neoplastic dermatoses in 34. 3% (37/108. Concerning inflammatory dermatoses, the most frequent were Zoon balanitis (27.8%, 30/108, followed by lichen sclerosus (15.7%, 17/108, psoriasis (11.1%, 12/108, and lichen planus (4.6%, 5/108. In patients with psoriasis, 10 had lesions only in the penis, similarly to all patients with lichen planus. The most frequent malignant tumor was squamous cell carcinoma (SCC (15.7%, 17/108. The most common in-situ tumor was erythroplasia of Queyrat (8.3%, 9/108. A case of basal cell carcinoma (BCC was found. Kaposi sarcoma and mycosis fungoides on penis were also diagnosed, as an additional form of presentation to their generalized disease. Conclusions: In this study, inflammatory diseases were the most frequently diagnosed dermatoses, while SCC was the most common malignant tumor found. In the majority of psoriasis and lichen planus cases, clinical lesions were only present in the genital area.

    Batra, Manu; Ishrat, A.

    2016-01-01

    Background: Utilization of health services is the actual attendance by the members of the public at health care facilities to receive care. Utilization, serves as an important tool for oral health policy decision-making. The aim of the present study was to retrospectively gauge and assess the utilization pattern of the dental treatments which was given in hospital for last 10 years. Materials and Methods: This retrospective infirmary based study was carried out at Sheri Kashmir Institute of Medical Sciences (SKIMS), Srinagar, Jammu and Kashmir, India. The yearly outpatient department (OPD) records for the utilization of specific dental treatment of a total of 103963 patients were assessed retrospectively from 2014 to 2003. Trend analysis was used to assess the trend of utilization of each speciality with best fitted linear trend lines. Results: The pattern of new patients has also shown a constant rise during the study period except for 2008 and 2009. The utilization of oral surgery speciality has shown a tremendous fall from 2003 to 2014 whereas the number of patients coming to periodontics and conservative dentistry has shown an increasing pattern. Conclusion: Utilization of oral health care has long been used as an indicator of oral health related behaviour of a population. In the present study it can be conclude that the outlook of the population under study has changed from blood and vulcanite dentistry outlook and is moving towards restorative dentistry. .

    Andersen, Lee O'Brien; Bonde, Ida; Nielsen, Henrik Bjørn; Stensvold, Christen Rune

    2015-07-01

    Blastocystis is a common single-celled intestinal parasitic genus, comprising several subtypes. Here, we screened data obtained by metagenomic analysis of faecal DNA for Blastocystis by searching for subtype-specific genes in coabundance gene groups, which are groups of genes that covary across a selection of 316 human faecal samples, hence representing genes originating from a single subtype. The 316 faecal samples were from 236 healthy individuals, 13 patients with Crohn's disease (CD) and 67 patients with ulcerative colitis (UC). The prevalence of Blastocystis was 20.3% in the healthy individuals and 14.9% in patients with UC. Meanwhile, Blastocystis was absent in patients with CD. Individuals with intestinal microbiota dominated by Bacteroides were much less prone to having Blastocystis-positive stool (Matthew's correlation coefficient = -0.25, P < 0.0001) than individuals with Ruminococcus- and Prevotella-driven enterotypes. This is the first study to investigate the relationship between Blastocystis and communities of gut bacteria using a metagenomics approach. The study serves as an example of how it is possible to retrospectively investigate microbial eukaryotic communities in the gut using metagenomic datasets targeting the bacterial component of the intestinal microbiome and the interplay between these microbial communities. © FEMS 2015.

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

    As a haemostatic irradiation is often proposed to patients suffering from a primitive bladder cancer, the authors report a retrospective mono-centric analysis of the effects of an external bi-dimensional palliative radiotherapy on patients taken into care for relapsing macroscopic hematuria after failure of local urological treatments. The assessment concerns the hematuria persistence, the interval without hematuric relapse, global survival, and transfusion needs. Based on a sample of 21 patients submitted to different irradiation schemes, the authors notice that a simple pelvic irradiation technique results in a fast symptomatic improvement of hematuria among fragile patients.

    The introduction of intra-arterial chemotherapy (IAC) as salvage treatment has improved the prognosis for eye conservation in group D retinoblastoma. The aim of this study was to compare the outcomes of consecutive patients with advanced unilateral disease treated with either first-line intravenous chemotherapy (IVC) or first-line IAC. This is a retrospective mono-centric comparative review of consecutive patients. Sporadic unilateral retinoblastoma group D cases treated conservatively at Jules-Gonin Eye Hospital and CHUV between 1997 and 2014. From January 1997 to August 2008, IVC, combined with focal treatments, was the primary treatment approach. From September 2008 to October 2014, IAC replaced IVC as first-line therapy. 48 patients met the inclusion criteria, receiving only either IAC or IVC as primary treatment modality. Outcomes of 23 patients treated by IVC were compared with those of 25 treated by IAC; mean follow-up was 105.3 months (range 29.2-218.6) and 41.7 months (range 19.6-89.5), respectively. Treatment duration was significantly shorter in the IAC group (pchemotherapy treatment. Despite this, the results reported here imply that eyes treated with first-line IAC will have shorter treatment period, better ocular survival and visual acuity than first-line IVC.

    2015-01-01

    Introduction Emphysematous pyelophritis (EPN) is a serious condition with significant mortality. The prognosis of patients with EPN has changed over the years. Mortality has declined with prompt and aggressive medical management and minimally invasive strategies. Aim To identify the prognostic factors and assess the outcome of conservative management of emphysematous pyelonephritis. Settings and Design This was a retrospective study of 8 consecutive patients who were diagnosed with EPN in two medical institutes between July 2010 and June 2015. Materials and Methods Eight consecutive patients diagnosed with emphysematous pyelonephritis between July 2010 and June 2015 was studied retrospectively. On the basis of Computerised tomographic scan findings they were grouped into four classes (1 to 4) according the modified classification recommended by Huang and Tseng. The management was conservative (combination of percutaneous drainage and antibiotics), immediate nephrectomy or delayed nephrectomy (when conservative management failed). Demographic, clinical, biochemical and radiological characteristics were assessed and compared between survivors and nonsurvivors. Results Seven (87.5%) of a total of 8 patients had diabetes mellitus. Escherichia coli (71.4 %) was the most common offending pathogen identified in pus culture. With conservative management in 7 patients (combination of percutaneous drainage and antibiotics), treatment was successful in 57.14 % and with immediate nephrectomy (one patient), the success rate was 100%. The risk factors for mortality were thrombocytopenia, shock and altered sensorium at presentation. The mortality rate in class 1, 2 and 3 was 0%, 33.3% and 66.7%. None of the patient had class 4 EPN. Conclusion A combination of percutaneous drainage with antibiotics offers an effective therapy for emphysematous pyelonephritis. PMID:26675196

    Previous retrospective analyses prove that impacted mandibular third molars (M3s) increase the risk of angle fractures and decrease the risk of concomitant fractures to the condyle. A retrospective cohort was designed for patients reported to the Department of Oral and Maxillofacial Surgery from January 2011 till June 2013. The study variables are presence or absence of third molar, if it is present, their position, classified using the Pell and Gregory system; angulation, classified using Shiller's method. The outcome variables were angle and condyle fractures. Hospital records and panoramic radiographs were used to determine and classify these variables. The study sample comprised of 118 mandibular angle and condyle fractures in 110 patients. Database was constructed and analysed using SPSS version 10.0. This present retrospective study concluded that the presence of impacted third molar predisposes the angle to fracture and reduces the risk of a concomitant condylar fracture. However absence of impacted third molar increases the risk of condylar fracture. The highest incidence of angle fracture was observed in position A impacted mandibular third molars. And there is no significant relationship, concerning ramus position and angulation of impacted mandibular third molars with the angle fracture.

    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.

  10. Human papillomavirus infection in Rio de Janeiro, Brazil: a retrospective study

    Directory of Open Access Journals (Sweden)

    M.O.O Carvalho

    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.

    2012-02-01

    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.

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

    To report the renal structural and functional anomalies in children with multicystic dysplastic kidneys. Retrospective descriptive analysis of 47 children with multicystic dysplastic kidney seen in a pediatric nephrology unit over a period of 6 years. Antenatal diagnosis of multicystic dysplastic kidney was made in 34 (72.3%) patients. On follow up of 31 children for more than 12 months, 21 (68%) had involution, 4 [13%] had non-regression, and 4 (13%) were nephrectomized. Vesico-ureteric reflux (n=13; 28%) was the commonest renal abnormality. The serum creatinine values were higher (P=0.006) in children with contralateral reflux. Sub-nephrotic proteinuria was noted in 9 (29%) and was significantly associated with complete involution (P=<0.023). None of the patients developed hypertension and 2 (6.4%) had renal failure. Close nephrological follow-up is needed in children with multicystic dysplasia of kidneys.

    There is increasing evidence that cerebral microangiopathy reduces number of brain metastases. Aim of this study was to analyse if vascular risk factors (arterial hypertension, diabetes mellitus, smoking, and hypercholesterolemia) or the presence of peripheral arterial occlusive disease (PAOD) can have an impact on number or size of brain metastases. 200 patients with pre-therapeutic 3D-brain MRI and available clinical data were analyzed retrospectively. Mean number of metastases (NoM) and mean diameter of metastases (mDM) were compared between patients with/without vascular risk factors (vasRF). No general correlation of vascular risk factors with brain metastases was found in this monocentric analysis of a patient cohort with several tumor types. Arterial hypertension, diabetes mellitus, hypercholesterolemia and smoking did not show an effect in uni- and multivariate analysis. In patients with PAOD the number of BM was lower than without PAOD. This was the case independent from cerebral microangiopathy but did not persist in multivariate analysis. From this first screening approach vascular risk factors do not appear to strongly influence brain metastasation. However, larger prospective multi-centric studies with better characterized severity of vascular risk are needed to more accurately detect effects of individual factors.

    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).

    Interactive Metronome (IM, The Interactive Metronome Company, Sunrise, Florida, USA) is a computer-based modality marketed to rehabilitation professionals who want to improve outcomes in areas of coordination, motor skills, self-regulation behaviors, and cognitive skills. This retrospective study examined the efficacy of IM training on improving timing skills, hand function, and parental report of self-regulatory behaviors. Forty eight children with mixed motor and cognitive diagnoses completed an average of 14 one-hour training sessions over an average of 8.5 weeks in an outpatient setting. Each child was assessed before and after training with the Interactive Metronome Long Form Assessment, the Jebsen Taylor Test of Hand Function, and a parent questionnaire. All three measures improved with statistical significance despite participants having no direct skill training. These results suggest an intimate relationship between cognition and motor skills that has potential therapeutic value. Level 4, Retrospective Case Series. Copyright © 2015 Hanley & Belfus.

    The Republic of Djibouti is an African country that exhibits one of the highest incidence rate of tuberculosis in the world. The aim of this study was to evaluate the prevalence of multidrug-resistant tuberculosis among new cases. We studied retrospectively every tuberculosis case diagnosed over a 12-month period in patients hospitalized at the French Military Hospital of Bouffard. During this period, 1,274 samples from 675 patients were tested. We isolated 266 mycobacteria corresponding to 180 cases of tuberculosis. Thirty-three were fully susceptible and 57% met the tuberculosis criteria, with 46% primary resistance. No extensively-drug-resistant tuberculosis was found. Our results highlight a major concern about the situation in this part of the world.

    2013-01-01

    Background Alveolar ridge keratosis (ARK) is a distinct, benign clinicopathological entity, characterized by a hyperkeratotic plaque or patch that occurs on the alveolar edentulous ridge or on the retromolar trigone, considered to be caused by chronic frictional trauma. The aim of this retrospective study is to present the clinicopathological features of 23 consecutive cases of ARK. Material and methods The 23 biopsy samples of ARK were selected and pathological features were revised (keratosis, acanthosis, surface architecture, and inflammation). Factors such as the patient’s gender, age, anatomical location, tobacco and alcohol use were analyzed. Results Sixteen out of the 23 cases studied were men and 7 women with a mean age of 55.05 (age ranged from 17 to 88 years). Thirteen cases had a history of tobacco habit, amongst whom, 4 also presented alcohol consumption. All the cases presented only unilateral lesions. Nineteen cases involved the retromolar trigone while 4 cases involved edentulous alveolar ridges. When observed microscopically, the lesions were mainly characterized by moderate to important hyperorthokeratosis. Inflammation was scanty or absent. In four of the cases, the presence of melanin pigment in the superficial corium or in the cytoplasm of macrophages was detected. None of the cases showed any features of dysplasia. Conclusion Our results reveal that ARK is a benign lesion. However, the high prevalence of smokers amongst the patients might suggest that some potentially malignant disorders such as tobacco associated leukoplakia may clinically mimic ARK. PMID:23587097

    The poor outcome of patients with recurrent ovarian cancer constitutes a continuous challenge for decision-making in clinical practice. In this setting, molecular targets have recently been identified, and novel compounds are now available. Bevacizumab has been introduced for the treatment of patients with ovarian cancer and is, to date, the most extensively investigated targeted therapy in this setting. However, potential toxicities are associated with the use of this monoclonal antibody. These toxicities have been reported in clinical trials, and can also be observed outside of trials. As limited data is currently available regarding the safety of bevacizumab treatment in daily clinical practice, the current retrospective study was designed to evaluate this. Data from 156 patients with recurrent ovarian cancer who had received bevacizumab treatment between January 2006 and June 2009 were retrospectively identified from the institutional records of five French centers. In contrast to clinical trials, the patients in the present study were not selected and had a heterogeneous profile according to their prior medical history, lines of treatment prior to bevacizumab introduction and number of relapses. The results first confirm the effect of heavy pretreatment on the occurrence of serious and fatal adverse events in clinical practice, as previously reported for clinical trials and for other retrospective cohort studies. Importantly, the data also demonstrates, for the first time, that medical history of hypertension is an independent predictive risk factor for the development of high-grade hypertension during bevacizumab treatment. These results thus suggest that treating physicians must consider all risk factors for managing bevacizumab toxicity prior to its introduction. Such risk factors include the time of bevacizumab introduction, a patient's history of hypertension and a low incidence of pre-existing obstructive disease. PMID:26998090

Nevertheless, a new tool is required for pain assessment needs in retrospective studies.Methods: The postoperative pain episodes, during the first postoperative day, of three patient groups were analyzed. Each pain episode was assessed by a visual analog scale, numerical rating scale, verbal rating scale, and a new tool – pain point system scale (PPSS – based on the analgesics administered. The type of analgesic was defined based on the authors’ clinic protocol, patient comorbidities, pain assessment tool scores, and preadministered medications by an artificial neural network system. At each pain episode, each patient was asked to fill the three pain scales. Bartlett’s test and Kaiser–Meyer–Olkin criterion were used to evaluate sample sufficiency. The proper scoring system was defined by varimax rotation. Spearman’s and Pearson’s coefficients assessed PPSS correlation to the known pain scales.Results: A total of 262 pain episodes were evaluated in 124 patients. The PPSS scored one point for each dose of paracetamol, three points for each nonsteroidal antiinflammatory drug or codeine, and seven points for each dose of opioids. The correlation between the visual analog scale and PPSS was found to be strong and linear (rho: 0.715; P <0.001 and Pearson: 0.631; P < 0.001.Conclusion: PPSS correlated well with the known pain scale and could be used safely in the evaluation of postoperative pain in retrospective studies.Keywords: pain scale, retrospective studies, pain point system

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

    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.

    Late-onset vitiligo, defined as being aged 50 years and above at the point of clinical onset, remains poorly characterized till now. This study aims to describe the clinical characteristics and treatment response of patients with late-onset vitiligo. We retrospectively reviewed the case records of all patients diagnosed with late-onset vitiligo, from January 1, 2010 to December 31, 2014. Information obtained included patient demographics, characteristics of vitiligo and treatment responses. Of the 3128 patients diagnosed with vitiligo over the 5-year period, 461 (14.7%) had late-onset disease. The study had more females (n = 260, 56.4%) than males, with an average onset age of 59.4 ± 7.4 years. Majority of patients were Chinese (n = 308, 66.8%) and 45 (9.8%) patients had an associated autoimmune disease. Focal vitiligo, defined as the localized presence of depigmented patches, was most common (n = 209, 45.3%). Treatment response was evaluated in 359 patients, of which 216 received monotherapy (topical creams: n = 210, 97.2%; phototherapy: n = 6, 2.8%) and 143 received both modalities. Fifty six (15.6%) patients received oral steroids. Patients who were treated with both topical creams and phototherapy yielded better clinical responses compared to those on monotherapy (P 50% return of pigmentation compared to baseline (vs. n = 66, 30.6% in the monotherapy group). The choice of phototherapy (targeted, narrowband ultraviolet B or psoralen + ultraviolet A) did not significantly affect clinical response (P = 0.774). This study is limited by its retrospective nature, the nonstandardized documentation resulting in the inability to determine disease progression and associated metabolic comorbidities and also by the gradual loss to follow-up of patients. Late-onset vitiligo is not uncommon and tends to be of the focal vitiligo subtype. Nonsegmented vitiligo is more prevalent than segmental vitiligo. Combination therapy with topical medications and phototherapy is superior

    Behavioral research has shown that spatial cues that orient attention toward task relevant items being maintained in visual short-term memory (VSTM) enhance item memory accuracy. However, it is unknown if these retrospective attentional cues ("retro-cues") enhance memory beyond typical short-term memory delays. It is also unknown whether retro-cues affect the spatial information associated with VSTM representations. Emerging evidence suggests that processes that affect short-term memory maintenance may also affect long-term memory (LTM) but little work has investigated the role of attention in LTM. In the current event-related potential (ERP) study, we investigated the duration of retrospective attention effects and the impact of retrospective attention manipulations on VSTM representations. Results revealed that retro-cueing improved both VSTM and LTM memory accuracy and that posterior maximal ERPs observed during VSTM maintenance predicted subsequent LTM performance. N2pc ERPs associated with attentional selection were attenuated by retro-cueing suggesting that retrospective attention may disrupt maintenance of spatial configural information in VSTM. Collectively, these findings suggest that retrospective attention can alter the structure of memory representations, which impacts memory performance beyond short-term memory delays.

All patients were scored on the basis of WHO scoring system. Patients with low risk (score /=7 received multiple agent chemotherapy with EMACO regimen. After completion of chemotherapy patients were followed for a minimum of 2 years. The response to treatment was evaluated during follow-up by clinical examination, beta hCG levels and imaging as and when required. Results: Out of 28 women only 27 could be evaluated, because 1 patient was lost to follow-up. Out of 27 patients, 18 patients (66.67% achieved complete remission with the first-line chemotherapy and additional 25.92% (7/27 achieved complete remission with second line chemotherapy resulting in complete remission of 92.5% (25/27. Conclusion: Gestational trophoblastic neoplasia is curable if patient is properly evaluated and scored. It shows good response to chemotherapy.

    Uterine-sparing procedures could be attractive in patients concerned about preservation of fertility and change in corporeal image and sexuality. Transvaginal uterosacral hysteropexy can provide an alternative mesh-free technique for uterine suspension. This study aimed to evaluate the feasibility of transvaginal uterine suspension to uterosacral ligaments in terms of operative data, complications, midterm efficacy, and patient satisfaction. This retrospective study analyzed the first 20 cases of transvaginal hysteropexy through bilateral high uterosacral ligaments (modified Shull technique) performed in our Institution. Mean follow-up was 33.2 months. The procedure was performed in 84 ± 19 min ,and blood loss was 228 ± 139 ml. Three mild complications (15 %) were observed. Recurrence [Pelvic Organ Prolapse Quantification system (POP-Q) stage ≥ II was observed in five patients (25 %), and three of them (15 %) required reintervention. Mean Patient Global Impression of Improvement score was "much improved." Two woman (40 %) who had not fulfilled their childbearing desire obtained a pregnancy. Both underwent elective caesarean section at term. Transvaginal uterosacral hysteropexy appears a feasible mesh-free technique for apical support. This procedure can be indicated in women with the desire of preserving fertility or who prefer a uterine-sparing surgical option.

    To investigate the correlation between the preoperative biometric parameters of the anterior segment and the vault after implantable Collamer lens (ICL) implantation via this retrospective study. Retrospective clinical study. A total of 78 eyes from 41 patients who underwent ICL implantation surgery were included in this study. Preoperative biometric parameters, including white-to-white (WTW) diameter, central corneal thickness, keratometer, pupil diameter, anterior chamber depth, sulcus-to-sulcus diameter, anterior chamber area (ACA) and central curvature radius of the anterior surface of the lens (Lenscur), were measured. Lenscur and ACA were measured with Rhinoceros 5.0 software on the image scanned with ultrasound biomicroscopy (UBM). The vault was assessed by UBM 3 months after surgery. Multiple stepwise regression analysis was employed to identify the variables that were correlated with the vault. The results showed that the vault was correlated with 3 variables: ACA (22.4 ± 4.25 mm2), WTW (11.36 ± 0.29 mm) and Lenscur (9.15 ± 1.21 mm). The regressive equation was: vault (mm) = 1.785 + 0.017 × ACA + 0.051 × Lenscur - 0.203 × WTW. Biometric parameters of the anterior segment (ACA, WTW and Lenscur) can predict the vault after ICL implantation using a new regression equation. © 2016 The Author(s) Published by S.

    Full Text Available Aim: Mortality rates are important outcome parameters after burn. The causes of mortality have been reported differently in the literature. The aim of the study was to identify parameters that are predictive of major morbidity factors and risk of mortality in patients with burn injury. Material and Methods: This study was performed among the patients who admitted to the burn center period between December 2001 and June 2010. Within this period, demographic data, treatment, and outcomes of treatment were reviewed and analyzed. Results: The burn patients were analysed retrospectively during 9-years period between December 2001 and January 2010. Burns caused by scalding were the most frequent (69.7 % followed by flames (24.4 %. 4.30 % of the patients died because of multisystem organ failure, septicaemia and cardiac respiratory failure. Conclusions:The most common cause of mortality was multiorgan failure according to our study. The mortality rates and causes of burn centers should be investigated retrospectively between different burn centres to determine the most common cause of mortality in burn centers.

    2013-01-01

    Objectives: Although several detailed studies concerning the patient profile and clinical features of oral lichen planus have been undertaken all over the world in different populations, a similar study has not yet been conducted in a Turkish population. The purpose of this retrospective study was to describe the demographic and clinical characteristics of a group of patients with oral lichen planus in Turkey. Study Design: Charts of 370 patients, from the archive of Oral Diagnosis and Radiology Department of Marmara University Faculty of Dentistry (Istanbul, Turkey), with histologically confirmed clinical diagnosis of oral lichen planus in the period 1990-2010 were retrospectively reviewed. Results: Of the 370 patients, 260 (70.3%) were women and 110 (29.7%) were men. The mean age was 49.84±13.41 years (range of 16-83). The lesions were asymptomatic in 63 patients (17%). Nearly half of the patients (47.6%) had multiple sites of involvement. Predominantly red forms were the most frequent, affecting 60.5% of patients. Approximately 17% of the patients had symptoms of possible extraoral involvement. No evidence suggesting a connection between oral lichen planus and tobacco or alcohol use was found. Only one out of the 370 cases had histologically proven malignant transformation. Conclusions: The patient profile and clinical features of oral lichen planus in Turkey were generally similar to those described in other populations. The preponderance of the red forms and also the fact that majority of patients referred themselves to our clinic highlighted the lack of awareness among Turkish health care providers about lichen planus. Key words:Oral lichen planus, clinical features, patient profile. PMID:23524413

    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

    Aim: To retrospectively assess the feasibility of transient elastography (TE) and the factors associated with failed and unreliable liver stiffness measurements (LSMs), in patients with chronic liver diseases. Material and methods: Our retrospective study included 8218 consecutive adult patients with suspected chronic liver diseases. In each patient, LSMs were performed with a FibroScan{sup ®} device (Echosens, France), with the M probe. Failure of TE measurements was defined if no valid measurement was obtained after at least 10 shots and unreliable if fewer than 10 valid shots were obtained, success rate (SR) <60% and/or interquartile range interval/median value (IQR/Med) ≥30%. Results: From the 8218 patients, failed and unreliable LSMs were observed in 29.2% of cases. In univariant analysis, the following risk factors were associated with failed and unreliable measurements: age over 50 years (OR 2.04; 95%CI 1.84–2.26), female gender (OR 1.32; 95%CI 1.20–1.45), BMI > 27.7 kg/m{sup 2} (OR 2.89, 95%CI 2.62–3.19), weight > 77 kg (OR 2.17; 95%CI 1.97–2.40) and height < 162 cm (OR 1.26; 95%CI 1.14–1.40). In multivariate analysis all the factors mentioned above were independently associated with the risk of failed and unreliable measurements. If all the negative predictive factors were present (woman, older than 50 years, with BMI > 27.7 kg/m{sup 2}, heavier than 77 kg and shorter than 162 cm), the rate of failed and unreliable measurements was 58.5%. In obese patients (BMI ≥ 30 kg/m{sup 2}), the rate of failed and unreliable measurements was 49.5%. Conclusion: Failed and unreliable LSMs were observed in 29.1% of patients. Female gender, older age, higher BMI, higher weight and smaller height were significantly associated with failed and unreliable LSMs.

    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

    Since mobile phones are always carried by individuals, the retrospective dosimetry using thermoluminescence (TL) and optically stimulated luminescence (OSL) characteristics of elements in mobile phone is intensively developing nowadays due to its advantages over conventional biological dosimetry techniques. Using a TL and OSL method on resistors and inductors in a mobile phone, a low background dose (zero dose) about tens of mGy is acquired in previous study. Radiation workers have to wear a dosimeter to assess individual exposure during their works. This monitoring system facilitate a fast medical treatment for highly exposed workers in case of a radiation accident. In the event of large-scale radiation accidents, where most of the subjects are ordinary people, it is difficult to evaluate the individual dose due to the absence of dosimeters. A technique for dose evaluation using a radiation dependency of various materials in the absence of a dosimeter is called retrospective dosimetry.

    Occ DEAS Assessing occupational exposure in retrospective community-based case-control studies is difficult as measured exposure data are very seldom available. The expert assessment method is considered the most accurate way to attribute exposure but it is a time consuming and expensive process and may be seen as subjective, non reproducible, and non transparent. In this paper, we describe these problems and outline our solutions as ope rationalized in a web-based software application (Occ DEAS). The novel aspects of Occ DEAS are combining all steps in the assessment into one software package; enmeshing the process of assessment into the development of questionnaires; selecting the exposure(s) of interest; specifying rules for exposure assignment; allowing manual or automatic assessments; ensuring that circumstances in which exposure is possible for an individual are highlighted for review; providing reports to ensure consistency of assessment. Development of this application has the potential to make high-quality occupational assessment more efficient and accessible for epidemiological studies

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

    Full Text Available 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.

    For a child, the likelihood of being murdered is highest during the first year of life, and many such cases are neonaticides. Although several recent studies have examined neonaticide in different countries and cultures, there has been no in-depth analysis of Swiss cases, even though this country has special neonaticide legislation and four "baby hatches" have been opened to prevent such killings. The primary objective of this retrospective study was to analyze the prevalence and phenomenon of neonaticide in Switzerland. Using data from judicial files, 11 cases were identified in 15 German-speaking cantons between 1980 and 2010. The sample included two uncommon cases of nonmaternal neonaticide. The discussion addresses possible prevention strategies.

    Full Text Available Abstract Background Median sternotomy infection and bony nonunion are two commonly described complications which occur in 0.4 - 5.1% of cardiac procedures. Although relatively infrequent, these complications can lead to significant morbidity and mortality. The aim of this retrospective study is to evaluate the initial experience of a transverse plate fixation system following wound complications associated with sternal dehiscence with or without infection following cardiac surgery. Methods A retrospective chart review of 40 consecutive patients who required sternal wound reconstruction post sternotomy was performed. Soft tissue debridement with removal of all compromised tissue was performed. Sternal debridement was carried using ronguers to healthy bleeding bone. All patients underwent sternal fixation using three rib plates combined with a single manubrial plate (Titanium Sternal Fixation System®, Synthes. Incisions were closed in a layered fashion with the pectoral muscles being advanced to the midline. Data were expressed as mean ± SD, Median (range or number (%. Statistical analyses were made by using Excel 2003 for Windows (Microsoft, Redmond, WA, USA. Results There were 40 consecutive patients, 31 males and 9 females. Twenty two patients (55% were diagnosed with sternal dehiscence alone and 18 patients (45% with associated wound discharge. Thirty eight patients went on to heal their wounds. Two patients developed recurrent wound infection and required VAC therapy. Both were immunocompromised. Median post-op ICU stay was one day with the median hospital stay of 18 days after plating. Conclusion Sternal plating appears to be an effective option for the treatment of sternal wound dehiscence associated with sternal instability. Long-term follow-up and further larger studies are needed to address the indications, benefits and complications of sternal plating.

    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.

    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.

    Breast cancer is one of the most common cancers in premenopausal women and its treatment may affect their fertility. Indeed, chemotherapy used in breast cancer may cause transient or permanent amenorrhea in premenopausal women. We conducted a retrospective study of young patients with localized breast canceri in the Department of Medical Oncology, Mohammed VI Inuversity Hospital, Oujda, Morocco over a 3-year period from January 2009 to December 2011. The aim of our study was to analyse the impact of chemotherapy-induced amenorrhea (CIA) as well as predictive factors for its occurrence. In our series, 74% of patients had CIA and 33.6% of patients had definitive chemotherapy-induced amenorrhea. Several factors have been studied in search of predictive factors for amenorrhea occurrence. With regard to the age factor, our analysis showed that women over 40 were more likely to have amenorrhea than those aged less than 40 years (95.7% versus 56.1%), with a statistically significant difference (p = 0.003). In our study the incidence of ICA seems comparable to that found in the literature, while age is the predominant predictor of its occurrence.

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

    Full Text Available AIM: To analyze childhood glaucoma regarding its demographics, presentations, different causes and surgical modalities used among patients in Dakahelia and to apply the Childhood Glaucoma Research Network (CGRN classification retrospectively to evaluate its convenience. METHODS: A retrospective study in which the medical files of all glaucoma patients <16 years old presented to Mansoura Ophthalmic Center, Mansoura University from 2014 to 2017, were retrieved and analyzed. Collected data included: age, gender, laterality, visual acuity (VA, refraction, intraocular pressure (IOP, corneal diameter, cup-disc ratio, types and number of surgeries and antiglaucomatous drugs (AGD at the first and last visit. Prevalence of different subtypes was calculated and means of clinical features were compared. RESULTS: A total of 305 eyes of 207 patients were included classified into 6 groups: primary congenital glaucoma (PCG, juvenile open angle glaucoma (JOAG, glaucoma associated with systemic disease, glaucoma associated with ocular anomalies, acquired glaucoma and glaucoma following cataract surgery. PCG was the predominant type (55.1% followed by acquired glaucoma (29.5%. Males represented 63.8% of the whole studied patients. Glaucoma associated with ocular anomaly group showed the youngest age at diagnosis (21.9±30.0mo. The shortest corneal diameter was recorded in post cataract group (10.4±0.5 mm. Highest cup-disc ratio was found in the PCG group (P<0.0005. Glaucoma associated with systemic disease presented with the highest baseline IOP (34.5±5.0 mm Hg. All the cases with PCG were treated surgically with 21.8% required more than one surgery. The majority of the patients (74.2% in the acquired group were treated medically. Combined trabeculotomy-trabeculectomy was the most frequent operation done, accounting for 34.5% of all primary surgeries. Ahmed valve implantation comprised 87% of the secondary surgeries. Acquired glaucoma group had the highest

    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. 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. 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). 'Conscious sedation' was the technique of choice for awake craniotomy, at our institute. Fentanyl, propofol, and dexmedetomidine were the main agents used for this purpose. Patients receiving propofol had less incidence of intraoperative seizure. Appropriate selection of patients, understanding the procedure of surgery, and judicious use of sedatives or anaesthetic agents are key to the

    To compare levels of bilirubin (using the area under the curve, AUC) in preterm infants before the onset of sepsis with healthy matched-controls. Preterm infants born between January 2011 and December 2015 with late-onset sepsis were enrolled in our retrospective study and were matched with healthy controls (sex, birth weight and gestational age). Levels of bilirubin were registered in the eight days preceding the onset of sepsis and the AUC was calculated for both groups. Eighty-eight neonates (44 cases) were studied. GA and BW did not differ between cases and controls. In cases, we found a higher value of AUC (30.7 versus 22.5; p = 0.021). In our retrospective cohort, we found that the levels of bilirubin and the AUC in the first eight days before the onset of sepsis in preterm infants were significantly higher than the healthy controls. These data suggest that the prolonged exposition to high levels of bilirubin could increase the infection susceptibility in preterm infants.

    Background: Ectodermal dysplasia (ED) is a group of rare, inherited disorders characterized by sparse hair, missing teeth and inability to sweat. Objective: To review and analyze cases of ED with an emphasis on clinical manifestations and parent's marriage history. Methodology: The present retrospective study was conducted by assessing the clinical records of nineteen cases of ED, available in the archives of the department; for age, gender, family history of consanguineous marriage and clinical manifestations. Results: It was observed that ED was more prevalent in males, with a ratio of 1.7:1. The hypohydrotic type was more common (78.95%) than hydrotic type (21.05%). The marriage history of parents revealed that 66.67% had consanguineous marriage and had 68.42% offspring's affected with ED; whereas 33.33% had history of non-consanguineous marriage and had 31.58% offspring's affected with ED. The clinical manifestations observed were- dry skin(94.74%); scaly skin(42.11%); sparse hair on scalp, eyebrows and eyelashes(100%); frontal bossing(63.18%); saddle nose (57.89%); hypertelorism (47.37%); nail abnormality(52.63%); normal sweat glands(21.05%); abnormal sweat glands(78.95%); hypoplastic maxilla(52.63%); protuberant lips (57.89%); palmo-plantar keratosis(21.05%); wrinkled & hyper pigmented facial skin(84.21%); partial anodontia(94.74%); conical shaped teeth(84.21%); high arched palate(68.42%); thin alveolar bone(100.00%); taurodontism(21.05%) and cleft lip & cleft palate(05.26%). The number of teeth present in all the cases ranged from 0 to 19. Conclusion: ED patients suffer from social problems and poor psychological and physiological development as a result of unacceptable esthetics and abnormal function of orofacial structures. Oral rehabilitation thus becomes mandatory, although it is often difficult; particularly in pediatric patients. PMID:24082749

    We conducted a retrospective analysis to investigate treatment results and prognostic factors of pediatric neuroblastoma patients. This retrospective study was carried out analyzing the medical records of patients with the pathological diagnosis of neuroblastoma seen at South Egypt Cancer Institute, Assiut University during the period from January 2001 and January 2010. After induction chemotherapy, response according to international neuoblastoma response criteria was assessed. Radiotherapy to patients with residual primary tumor was applied. Overall and event free survival (OAS and EFS) rates were estimated using Graphed prism program. The Log-rank test was used to examine differences in OAS and EFS rates. Cox-regression multivariate analysis was done to determine the independent prognostic factors affecting survival rates. Fifty three cases were analyzed. The median follow-up duration was 32 months and ranged from 2 to 84 months. The 3-year OAS and EFS rates were 39.4% and 29.3% respectively. Poor prognostic factors included age >1 year of age, N-MYC amplification, and high risk group. The majority of patients (68%) presented in high risk group, where treatment outcome was poor, as only 21% of patients survived for 3 year. Multivariate analysis confirmed only the association between survival and risk group. However, in univariate analysis, local radiation therapy resulted in significant survival improvement. Therefore, radiotherapy should be given to patients with residual tumor evident after induction chemotherapy and surgery. Future attempts to improve OAS in high risk group patients with aggressive chemotherapy and bone marrow transplantation should be considered.

    Purpose. - Surgery is the treatment of choice for localized uterine sarcomas. We conducted a retrospective study to define prognostic factors. Patients and methods. - We studied 111 cases of patients treated by adjuvant radiotherapy for uterine sarcoma in seven French centers. The median decline was 31 months. We conducted a univariate analysis to identify factors correlated with local recurrence. The statistically significant factors were studied in multivariate analysis by Cox model. Results. - The median dose of external beam radiotherapy was 45 Gy. Forty-three percent of patients had vaginal vault brachytherapy and 21 % chemotherapy. Only 6.3 % of patients had complications of acute grade III and 8.1 % of long-term sequelae of radiotherapy. The survival rate at 5 years was 74.6 %. They noted 12.6 % of isolated locoregional recurrences, against 29.7 % for distant recurrences, 80 % were pulmonary. Factors correlated with the risk of locoregional relapse were menopausal status (P = 0.045) and surgical margins suspicious or not healthy (P = 0.0095). The chemotherapy did not improve overall survival or disease free survival but the numbers were low. Conclusion. - The postoperative radiotherapy provides good local control in this disease. Brachytherapy is sometimes done, but it does not improve local control. Chemotherapy is not a standard localized stage but the rate of metastatic recurrence calls for the development of strategies involving systemic treatment with radiotherapy. (authors)

    Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma encountered in childhood and adolescence. Early diagnosis of pediatric cases is critical to improving outcomes, especially when socioeconomic status and geographical access to specialist services can reduce opportunities for early cancer detection and treatment. The objective of this study is to determine factors that can delay referral and treatment in specialist pediatric oncology center upon our population specificities. This retrospective study involved 31 children between 2003 and 2013. Children affected by histologically confirmed RMS occurring as a primary lesion in the orofacial area were included. The median age was 8 ± 4.22 years (range: 3 months - 15 years). The male to female ratio was 1.8:1. Most of the patients had advanced stage disease at presentation (81.7% group had 3-4 pretreatment staging) with parameningeal involvement in 80.6% of the cases. The 2-year event-free survival rate was 17.7 ± 7.8% for all the patients. Delay of admission to our unit and abandonment of treatment seem to be important factors for the dismal prognosis. Patient's location, socioeconomic status and health care coverage have had an impact on longer delays in seeking care and on follow-up. More studies are needed for implementation of a better management practices and a better supportive care upon specificities of our population.

    The thyroid carcinoma (TC) is not very frequent among all cancer. Its course is slow and is high potentially curable. Our aim was to analyse the characteristics in patients with TC. A retrospective analysis on 171 patients, with an average age of 41.1. (± 14.6), who asked for TC to our service between the years 2000-2004, was performed. From case histories it was evaluated: anamnesis, diagnostic image, histopathology and evolution. Tumours were grouped for size and TNM (tumor-nodule-metastasis) in stage (S). A simulated serum thyroglobulin level >2 ng/ml and positive image with 131 I or another nuclear marker were considered as positive for residual TC. In the totality of the analyzed patients 88% were female, 62% below 45 years old, and in 77% the thyroid function was normal. The fine needle aspiration (FNA) was diagnostic in 78%. Papillary thyroid carcinoma (PTC) in 96%. The 63% was SI; 14% SII; 19% SIII and 4% SIV. During follow-up, we observed that 90% of patients with Tg between 2 and 10 had evidence of residual TC, and 100% with Tg > 10 ng/ml, whereas 18% of those whose simulated Tg [es

    2013-05-09

    Rationale: Four monocentric studies reported that circadian rhythms can affect left ventricular infarct size after ST-segment-elevation acute myocardial infarction (STEMI). Objective: To further validate the circadian dependence of infarct size after STEMI in a multicentric and multiethnic population. Methods and Results: We analyzed a prospective cohort of subjects with first STEMI from the First Acute Myocardial Infarction study that enrolled 1099 patients (ischemic time <6 hours) in Italy, Scotland, and China. We confirmed a circadian variation of STEMI incidence with an increased morning incidence (from 6:00 am till noon). We investigated the presence of circadian dependence of infarct size plotting the peak creatine kinase against time onset of ischemia. In addition, we studied the patients from the 3 countries separately, including 624 Italians; all patients were treated with percutaneous coronary intervention. We adopted several levels of analysis with different inclusion criteria consistent with previous studies. In all the analyses, we did not find a clear-cut circadian dependence of infarct size after STEMI. Conclusions: Although the circadian dependence of infarct size supported by previous studies poses an intriguing hypothesis, we were unable to converge toward their conclusions in a multicentric and multiethnic setting. Parameters that vary as a function of latitude could potentially obscure the circadian variations observed in monocentric studies. We believe that, to assess whether circadian rhythms can affect the infarct size, future study design should not only include larger samples but also aim to untangle the molecular time-dynamic mechanisms underlying such a relation. © 2013 American Heart Association, Inc.

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

    Full Text Available This retrospective study determined the frequency of orthopedic diseases in horses. 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 %.

    The aim of this study is to investigate the safety and efficacy of castor oil to induce labour. A retrospective observational case control study was conducted over five years. Castor oil was proposed to women referred to the Birth Centre (Castor Oil group (COG)). They were compared to women who chose to be followed by the traditional doctor-led unit (control group (CG)). Castor oil was administered in a 60 ml single dose in 200 ml of warm water. Inclusion criteria were gestational age between 40 and 41 weeks plus premature rupture of membranes between 12 and 18 hours or amniotic fluid index ≤4 or Bishop Score of ≤4 or absence of spontaneous labour over 41 + 4 weeks. Pharmacological induction of labour was required for 18 women in the COG (45%) and 36 in the CG (90%) (p oil showed a higher incidence of vaginal delivery, whereas the incidence of caesarean section was lower in the COG, but no statistical significance was reached. The use of castor oil is related to a higher probability of labour initiation within 24 hours. Castor oil can be considered a safe non-pharmacological method for labour induction.

    Patella lowering aims to improve quadriceps function as a means of correcting crouch gait in patients with cerebral palsy. Few studies have assessed the effects of patella lowering as a component of multilevel surgery. Including patella lowering into the components of multilevel surgery is beneficial in patients with crouch gait and patella alta. In 12 lower limbs with patella alta (Caton-Deschamps index>1.4) in 41 children with cerebral palsy, patella lowering was performed, without distal femoral extension osteotomy or hamstring release. Among limbs with similar surgical procedures (e.g., hamstring lengthening, rectus femoris transfer) except for patella lowering, controls were selected retrospectively by matching on a propensity score for patella lowering. The propensity score was computed based on preoperative knee flexion contracture, knee extension lag, and minimum knee flexion at mid-stance. Clinical and 3D kinematic data were compared between the two groups. The improvement in minimum knee flexion at mid-stance was significantly greater in the group with patellar lowering (-24°±12°vs. -12°±7°). The Gait Deviation Index improved similarly in the two groups. Knee flexion contracture improved only in the group with patellar lowering. Extension lag did not improve in either group. Peak knee flexion during the swing phase remained unchanged in both groups. Patellar lowering is effective in diminishing minimum knee flexion at mid-stance in patients with patella alta and crouch gait due to cerebral palsy. Patellar lowering has not adverse effects on gait. These findings cannot be assumed to apply to patients with normal patellar height. IV (retrospective study). Copyright © 2017.

    A retrospective multicenter study. Routine cervical spine surgeries are typically associated with low complication rates, but serious complications can occur. Intraoperative death is a very rare complication and there is no literature on its incidence. The purpose of this study was to determine the intraoperative mortality rates and associated risk factors in patients undergoing cervical spine surgery. Twenty-one surgical centers from the AOSpine North America Clinical Research Network participated in the study. Medical records of patients who received cervical spine surgery from January 1, 2005, to December 31, 2011, were reviewed to identify occurrence of intraoperative death. A total of 258 patients across 21 centers met the inclusion criteria. Most of the surgeries were done using the anterior approach (53.9%), followed by posterior (39.1%) and circumferential (7%). Average patient age was 57.1 ± 13.2 years, and there were more male patients (54.7% male and 45.3% female). There was no case of intraoperative death. Death during cervical spine surgery is a very rare complication. In our multicenter study, there was a 0% mortality rate. Using an adequate surgical approach for patient diagnosis and comorbidities may be the reason how the occurrence of this catastrophic adverse event was prevented in our patient population.

    The Essure(®) system is a hysteroscopic sterilization method. The aim of our study is to retrospectively evaluate the sterilization procedure with Essure(®) devices, with and without anesthesia, and in particular with hypnosis. The descriptive study includes all tubal sterilization with Essure(®) performed during the year 2009 at the Maternité régionale de Nancy. Hypnosis efficiency is retrospectively evaluated with Verbal Numeric Rating Scale (VNRS) for peroperative pain, and analgesic medication use for postoperative pain. Ninety-four sterilizations are performed, 85% (85/94) of them without anesthesia. The mean VNRS is 3.0. The mean operative time is 8.7 minutes, positively correlated with the VNRS (P=0.0005). The rate of successful insertion is 94%. At 3 months, 91% of the implants have a correct location. Inadequate locations are more frequent when anesthesia have been performed (37% vs 4%, P=0.016). There is no significant difference between groups with and without hypnosis for the VNRS, the failure rate and the use of analgesic medication. Tubal sterilization with the Essure(®) system is a quick and efficient method. Our study does not demonstrate efficiency of hypnosis in pain control. This remains to be explored with a prospective study, including others parameters, such as anxiety. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    Objective: To retrospectively investigate the long-term swallowing function of patients with laryngeal carcinoma, who underwent partial laryngectomy, discuss the effectiveness and reliability of Kubota drinking test in the assessment of patients with dysphagia, who underwent partial laryngectomy, and analyze the influence of different ways of operation on swallowing function. Methods: Clinical data were retrospectively analyzed on 83 patients with laryngeal carcinoma, who underwent partial laryngectomy between September 2012 and August 2015. Questionnaire survey, Kubota drinking test and video fluoroscopic swallowing study (VFSS) were conducted for patients during a scheduled interview. Patients were grouped by two ways: the one was whether epiglottis was retained, and the other was whether either arytenoids or both were reserved. The influence of different surgical techniques on swallowing function was analyzed according to the results of Kubota drinking test. The agreement and reliability of Kubota drinking test were statistically analyzed with respect to VFSS treated as the gold standard. SPSS23.0 software was used to analyze the data. Results: Questionnaire results revealed that among 83 patients underwent partial laryngectomy 32.53% suffered from eating disorder, and 43.37% experienced painful swallowing. The incidence of dysphagia was 40.96% according to the results of Kubota drinking test. There was statistical difference between the group with epiglottis remained and that having epiglottis removed in terms of the absence of dysphagia and severity. The statistical values of normal, moderate and severe dysphagia were in the order of 18.160, 7.229, 12.344( P dysphagia as well as that of intermediate severity, and their statistical values were 4.790 and 9.110( P dysphagia post partial laryngectomy.

    Studies have reported that the tunnelled dialysis catheter (TDC) is associated with inferior haemodialysis (HD) patient survival, in comparison with arteriovenous fistula (AVF). Since many cofactors may also affect survival of HD patients, it is unclear whether the greater risk for survival arises from TDC per se, or from associated conditions. Therefore, the aim of this study was to determine, in a multivariate analysis, the long-term outcome of HD patients, with respect to vascular access (VA). Retrospective cohort study. This retrospective cohort study included all 156 patients with a TDC admitted at University Hospital Merkur, from 2010 to 2012. The control group consisted of 97 patients dialysed via AVF. The groups were matched according to dialysis unit and time of VA placement. The site of choice for the placement of the TDC was the right jugular vein. Kaplan-Meier analysis with log-rank test was used to assess patient survival. Multivariate Cox regression analysis was used to determine independent variables associated with patient survival. Patient survival with respect to VA. The cumulative 1-year survival of patients who were dialysed exclusively via TDC was 86.4% and of those who were dialysed exclusively via AVF, survival was 97.1% (p=0.002). In multivariate Cox regression analysis, male sex and older age were independently negatively associated with the survival of HD patients, while shorter HD vintage before the creation of the observed VA, hypertensive renal disease and glomerulonephritis were positively associated with survival. TDC was an independent risk factor for survival of HD patients (HR 23.0, 95% CI 6.2 to 85.3). TDC may be an independent negative risk factor for HD patient survival.

    Purpose. - Surgery is the treatment of choice for localized uterine sarcomas. We conducted a retrospective study to define prognostic factors. Patients and methods. - We studied 111 cases of patients treated by adjuvant radiotherapy for uterine sarcoma in seven French centers. The median decline was 31 months. We conducted a univariate analysis to identify factors correlated with local recurrence. The statistically significant factors were studied in multivariate analysis by Cox model. Results. - The median dose of external beam radiotherapy was 45 Gy. Forty-three percent of patients had vaginal vault brachytherapy and 21 % chemotherapy. Only 6.3 % of patients had complications of acute grade III and 8.1 % of long-term sequelae of radiotherapy. The survival rate at 5 years was 74.6 %. They noted 12.6 % of isolated locoregional recurrences, against 29.7 % for distant recurrences, 80 % were pulmonary. Factors correlated with the risk of locoregional relapse were menopausal status (P = 0.045) and surgical margins suspicious or not healthy (P = 0.0095). The chemotherapy did not improve overall survival or disease free survival but the numbers were low. Conclusion. - The postoperative radiotherapy provides good local control in this disease. Brachytherapy is sometimes done, but it does not improve local control. Chemotherapy is not a standard localized stage but the rate of metastatic recurrence calls for the development of strategies involving systemic treatment with radiotherapy. (authors)

Retrospective, descriptive study of leprosy in the Municipality of Cumanayagua, Cuba, from 2006 to 2011. Study universe are all cases occurring during this period and are consistent with the sample. Data were obtained from the Municipal Center for Hygiene and Epidemiology records, as well as from the survey conducted by the National Leprosy Control for each new case. The results were analyzed with SPSS 15.0, and are presented in tables. Results. Incidence was silent during prolonged periods of the study phase with a marked rise in in 2009. Females were affected most by leprosy during the selected study period reaching 54.2% of the total sample. Indeterminate leprosy and tuberculoid leprosy predominated, with respective rates of 37.5% and 29.1%. In 41.6% of leprosy patients, over a year elapsed between the onset of symptoms and diagnosis. 83.3% of patients spontaneously went to the doctor for diagnosis while only 4.2% were diagnosed through contact tracing. Multibacillary leprosy prevailed in 62.5% of cases. Conclusion. In 2009, there was evidence of a significant increase in the incidence of leprosy in the municipality under study reaching a rate of 15.0 per 100,000 inhabitants.

  11. Determinants of urban sprawl in European cities.

    2015-07-01

    This paper provides empirical evidence that helps to answer several key questions relating to the extent of urban sprawl in Europe. Building on the monocentric city model, this study uses existing data sources to derive a set of panel data for 282 European cities at three time points (1990, 2000 and 2006). Two indices of urban sprawl are calculated that, respectively, reflect changes in artificial area and the levels of urban fragmentation for each city. These are supplemented by a set of data on various economic and geographical variables that might explain the variation of the two indices. Using a Hausman-Taylor estimator and random regressors to control for the possible correlation between explanatory variables and unobservable city-level effects, we find that the fundamental conclusions of the standard monocentric model are valid in the European context for both indices. Although the variables generated by the monocentric model explain a large part of the variation of artificial area, their explanatory power for modelling the fragmentation index is relatively low.

    A body of evidence supports the use of low tidal volumes in ventilated patients without lung pathology to slow progress to acute respiratory distress syndrome (ARDS) due to ventilator associated lung injury. We undertook a retrospective chart review and tested the hypothesis that tidal volume is a predictor of mortality in cardiothoracic (medical and surgical) critical care patients receiving invasive mechanical ventilation. Independent predictors of mortality in our study included: type of surgery, albumin, H + , bilirubin, and fluid balance. In particular, it is important to note that cardiac, thoracic, and transplant surgical patients were associated with lower mortality. However, our study did not sample equally from The Berlin Definition of ARDS severity categories (mild, moderate, and severe hypoxemia). Although our study was not adequately powered to detect a difference in mortality between these groups, it will inform the development of a large prospective cohort study exploring the role of low tidal volume ventilation in cardiothoracic critically ill patients.

    The need for totally implantable central venous access devices (TICVADs) has increased with increased opportunities in the use of chemotherapy and parenteral nutrition. This study aimed to determine the outcomes of TICVAD implantation and use in patients aged ≥85 years. Between January 2010 and August 2016, 117 patients underwent TICVAD implantation and their records were retrospectively reviewed. Participants were divided into 2 groups (plus-85 and sub-85 groups). Fifty-five patients (47.0%) had solid organ cancer alone; 35 patients (29.9%) had cerebrovascular or cranial nerve disease. The average follow-up period was 201 (2-1,620) days. Major complications were identified in 6 (14.6%) plus-85 patients and 11 (14.5%) sub-85 patients (p = 0.9813). Catheter-related infections developed in 3 plus-85 (7.3%) and 4 sub-85 patients (5.3%; p = 0.6549). There were no significant group differences in hematoma, pneumothorax, occlusion, and removal rates. In plus-85 patients examined just before surgery and a month after surgery, increased rates of serum albumin and Onodera's prognostic nutritional index were observed in 48% (14/39) and 41% (12/39), respectively. The use of TICVADs in the plus-85 group resulted in effective outcomes. The results of this retrospective study support the wider use of TICVADs in patients aged ≥85 years. © 2018 S.

    The purpose of this study was to compare the predictive validity, economic efficiency, and faculty staff satisfaction of a computerized test versus a personal interview as admission methods for graduate nursing studies. A mixed method study was designed, including cross-sectional and retrospective cohorts, interviews, and cost analysis. One hundred and thirty-four students in the Master of Nursing program participated. The success of students in required core courses was similar in both admission method groups. The personal interview method was found to be a significant predictor of success, with cognitive variables the only significant contributors to the model. Higher satisfaction levels were reported with the computerized test compared with the personal interview method. The cost of the personal interview method, in annual hourly work, was 2.28 times higher than the computerized test. These findings may promote discussion regarding the cost benefit of the personal interview as an admission method for advanced academic studies in healthcare professions. © 2016 John Wiley & Sons Australia, Ltd.

Settings and design: Retrospective analysis. Materials and Methods: A total of 2123 cycles undergone by 871 couples during the period of 5 years (2011–2015 were retrospectively studied. Statistical Analysis Used: Each of the factors was compared with pregnancy outcome (PO using statistical analysis with a confidence interval of 95% in SPSS software version 19. Chi-square test and logistic regression analysis method were used to determine the significance of each factor with the PO. Results: Among the various factors included in our study population, male habits (P = 0.004, male occupational environment (P = 0.025, male age (P = 0.002, and female age (P = 0.001 were found to significantly influence the PO following IUI. Conclusion: Our results indicate that avoiding smoking and alcohol consuming prior and during the IUI treatment along with working in low-heat-generating environment might lead to better success following the treatment.

    Two studies on the radiotherapy of laryngeal cancer were completed at the Radiotherapy Department of the Cancer Center Warsaw at the end of 1999. One of them was a multicenter randomized clinical trial, and the second one - a retrospective study on patients treated between years 1989 and 1995. An opinion exists that the trial outcomes of the conventional arm correspond to the outcomes of everyday practice. The subject of the study was to evaluate this thesis, and to find out, whether the outcomes of prospective and retrospective studies following the same treatment protocol are comparable. Selection criteria were - age ≤75, WHO 0-1, T1, T2, T3, N0, M0 stage of glottic and supraglottic laryngeal cancer. The treatment was: 66 Gy/2 Gy/33 fraction/45 days. The prospective group had - 199 patients, and the retrospective group: 150 patients. The two groups were comparable according to the age, site, sex and mean hemoglobin level. There was a significant difference in T-stage and performance status between the two groups. Overall survival, local control and CR-response were analyzed. To eliminate the influence of the differences in T=stage and performance status, regression models were applied - Cox's for survival and local control, logit for CR-response endpoint. The protocol compliance (prospective, retrospective) was as follows - total dose: (88%, 49%), treatment time: (47%, 11%) respectively. Three-year survival for the prospective and the retrospective groups were 89% and 74%, respectively (p=0.035), CR-response rates were 96% and 75%, respectively (p<0.001). There were no significant differences in probability of local recurrence in CR patients. A better outcome of treatment was observed in the prospective study group. It is probably due to a certain 'over-selection' of patients for the prospective study and many deviations from the therapeutic protocol in the historical group. 'Conventional treatment' has the same meaning in the prospective and retrospective

    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.

    Full Text Available Introduction Rhabdomyosarcoma (RMS is the most common soft tissue sarcoma encountered in childhood and adolescence. Early diagnosis of pediatric cases is critical to improving outcomes, especially when socioeconomic status and geographical access to specialist services can reduce opportunities for early cancer detection and treatment. Objective The objective of this study is to determine factors that can delay referral and treatment in specialist pediatric oncology center upon our population specificities. Methods This retrospective study involved 31 children between 2003 and 2013. Children affected by histologically confirmed RMS occurring as a primary lesion in the orofacial area were included. Results The median age was 8 ± 4.22 years (range: 3 months – 15 years. The male to female ratio was 1.8:1. Most of the patients had advanced stage disease at presentation (81.7% group had 3–4 pretreatment staging with parameningeal involvement in 80.6% of the cases. The 2-year event-free survival rate was 17.7 ± 7.8% for all the patients. Delay of admission to our unit and abandonment of treatment seem to be important factors for the dismal prognosis. Conclusion Patient's location, socioeconomic status and health care coverage have had an impact on longer delays in seeking care and on follow-up. More studies are needed for implementation of a better management practices and a better supportive care upon specificities of our population.

    Full Text Available Remembering the emotions we have experienced in the past is the core of one´s unique life-experience. However, there are many factors, both at the state and trait level that can affect the way past feelings are seen. The main aim of the current study was to examine the impact of individual differences on systematic biases in retrospective ratings compared to the momentary experience of basic emotions such as sadness, fear, happiness, and anger. To this end, an experience sampling study across two weeks was conducted using a younger and an older age-group; the experience of momentary emotions was assessed on 7 randomly determined occasions per day, the retrospective ratings being collected at the end of each day about that day, as well as at the end of the study about the previous two weeks. The results indicated that age and daily tiredness have significant effects on retrospective emotion ratings over a one-day period (state level, enhancing the retrospective ratings of negative emotions and decreasing the ratings of felt happiness. Whereas personality traits influence the more long-term emotion experience (trait level, with all Big Five personality traits having selective impact on retrospective emotion ratings of fear, sadness, happiness, and anger. Findings provide further evidence about the systematic biases in retrospective emotion ratings, suggesting that, although retrospective ratings are based on momentary experience, daily tiredness and personality traits systematically influence the way in which past feelings are seen.

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

    The possibility of using ordinary household table salt for dosimetry is suggested by its high sensitivity to ionising radiation, which generates a readout of optically stimulated luminescence (OSL). However, to exploit this finding for retrospective human dosimetry, it would be needed to find salt in close proximity to the exposed individual. Finding salty snacks frequently tucked into handbags, backpacks or pockets seemed to be a possibility; these items therefore became the test materials of the present study. The aluminium or cardboard packages used to exclude the moisture that makes crisps and nuts go soft and stale also helps to retain the induced OSL signal. Therefore, different snacks, either their salt component alone or mixed with the snack, are exposed to ionising radiation and then were assessed for their dosimetric properties. The results indicate the feasibility of using some salty snacks for dosimetry, with a minimum detectable dose as low as 0.2 mGy (authors)

    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.

    Behavioral evidence from the young suggests spatial cues that orient attention toward task relevant items in visual working memory (VWM) enhance memory capacity. Whether older adults can also use retrospective cues (“retro-cues”) to enhance VWM capacity is unknown. In the current event-related potential (ERP) study, young and old adults performed a VWM task in which spatially informative retro-cues were presented during maintenance. Young but not older adults’ VWM capacity benefitted from retro-cueing. The contralateral delay activity (CDA) ERP index of VWM maintenance was attenuated after the retro-cue, which effectively reduced the impact of memory load. CDA amplitudes were reduced prior to retro-cue onset in the old only. Despite a preserved ability to delete items from VWM, older adults may be less able to use retrospective attention to enhance memory capacity when expectancy of impending spatial cues disrupts effective VWM maintenance.

    Contingency learning is essential for establishing predictive or causal judgements. Retrospective revaluation captures essential aspects of the updating of this knowledge, according to new experience. In the present study, retrospective revaluation and its neural substrate was investigated in a rat conditioned magazine approach. One element of a previously food-reinforced Tone-Light compound stimulus was either further reinforced (inflation) or extinguished (extinction). These treatments affected the predictive value of the alternate stimulus (target), but only when the target was a weakly salient stimulus such as a Light, and the inflation/extinction procedure concerned the more salient element, that is the Tone. As the predictive value of the Light was decreased in comparison with a relevant control group, this revaluation was interpreted as backward blocking, and not unovershadowing. This observation challenges retrospective revaluation models focused on acquisition and prediction error detection, and is better accounted for by retrieval-based associative theories such as the comparator model (Miller and Matzel) [5]. Immunohistochemical detection of the Fos protein after the test phase revealed activation of the orbitofrontal and infralimbic cortices as well as nucleus accumbens core and shell, in rats that exhibited retrospective revaluation. Our results suggest that rats integrate successive experiences at the retrieval stage of retrospective revaluation, and that prefronto-accumbal interactions are involved in this function.

    Refeeding syndrome describes a pattern of electrolyte disturbances occurring after the reintroduction of nutrition to the malnourished patient; it is often associated with delirium. The authors investigated whether hospitalized elderly patients who develop delirium are more likely to have laboratory findings consistent with refeeding syndrome. The authors conducted a retrospective chart review of 100 patients over age 60. Charts were examined for indications of delirium and refeeding syndrome. Significantly lower serum levels of magnesium and phosphate were found in patients with delirium. Delirium was not associated with any significant difference in levels of potassium. This study supports an association between delirium in elderly patients and electrolyte changes consistent with those seen in refeeding syndrome.

    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.

    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 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.

  14. Generalizability of causal inference in observational studies under retrospective convenience sampling.

    Many observational studies adopt what we call retrospective convenience sampling (RCS). With the sample size in each arm prespecified, RCS randomly selects subjects from the treatment-inclined subpopulation into the treatment arm and those from the control-inclined into the control arm. Samples in each arm are representative of the respective subpopulation, but the proportion of the 2 subpopulations is usually not preserved in the sample data. We show in this work that, under RCS, existing causal effect estimators actually estimate the treatment effect over the sample population instead of the underlying study population. We investigate how to correct existing methods for consistent estimation of the treatment effect over the underlying population. Although RCS is adopted in medical studies for ethical and cost-effective purposes, it also has a big advantage for statistical inference: When the tendency to receive treatment is low in a study population, treatment effect estimators under RCS, with proper correction, are more efficient than their parallels under random sampling. These properties are investigated both theoretically and through numerical demonstration. Published 2018. This article is a U.S. Government work and is in the public domain in the USA.

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

    Full Text Available BACKGROUND Younger age pregnancy of the group 18 years to 19 years is characterized by adverse maternal outcomes like anaemia, hypertension, low birth weight babies and intra uterine growth restriction. A comparative retrospective study on the obstetric outcome in teenage mothers and older women was carried out. Data for the study was obtained from a hospital where considerable teenage pregnancy is reported. Evidence obtained in this study regarding antenatal complications and birth weight shows that good antenatal care and support by family and caregivers can bring down the incidence of anaemia and low birth weight babies in teenage pregnancy. The aim of the study is to compare the obstetric outcome of pregnancy in teenagers and older women in a tertiary care hospital. MATERIALS AND METHODS This was a retrospective study conducted in Government Medical College, Manjeri, Malappuram, Kerala, India for a period of three months from March 2017 to May 2017. This is a teaching hospital with annual delivery rate of around 3500. Obstetric outcome of young mothers in the age group 18 -19 years were compared to older women (20-38 years delivering in the same hospital. A total of 843 deliveries were considered, out of which 87 belonged to teenage group. They were compared in terms of social and educational data, age, number of pregnancy, antenatal care, complications, mode of delivery, birth weight, episiotomy and perineal tears. RESULTS The incidence of teenage pregnancy was fairly high. (10.3% Most of them were in their first pregnancy. A significant number of teenage pregnant mothers (72.4% had completed higher secondary education as compared to (27.6% in older women. Contrary to many prior studies, teenage pregnancies showed less anaemia (6.9% versus 12% and lesser incidence of low birth weight babies in comparison to older women. Preterm birth was higher in teenage group (33.1% and incidence of hypertensive disorders and intrauterine growth

    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.

    The paths via which childhood experiences influence well-being in adulthood are not well defined because most research relies on retrospective reports. This study examined the influence of demographic characteristics and current mood states on the reliability of reports of childhood experiences. The Child Experiences Scale (CES) was administered in 1996 and 2001 to participants in the Davis Longitudinal Study (N = 571; age range 22-61 years). Responses showed moderate to high cross-time reliability. Males were slightly more likely to change their responses. The influence of mood states was weak and more evident for global ratings of childhood than for specific experiences. These findings support the use of retrospective reports of childhood.

    Currently, many scholars are concerned about the treatment of postoperative infection; however, few have completed multivariate analyses to determine factors that contribute to the risk of infection. Therefore, we conducted a multivariate analysis of a retrospectively collected database to analyze the risk factors for acute surgical site infection following lumbar surgery, including fracture fixation, lumbar fusion, and minimally invasive lumbar surgery. We retrospectively reviewed data from patients who underwent lumbar surgery between 2014 and 2016, including lumbar fusion, internal fracture fixation, and minimally invasive surgery in our hospital's spinal surgery unit. Patient demographics, procedures, and wound infection rates were analyzed using descriptive statistics, and risk factors were analyzed using logistic regression analyses. Twenty-six patients (2.81%) experienced acute surgical site infection following lumbar surgery in our study. The patients' mean body mass index, smoking history, operative time, blood loss, draining time, and drainage volume in the acute surgical site infection group were significantly different from those in the non-acute surgical site infection group (p operative type in the acute surgical site infection group were significantly different than those in the non-acute surgical site infection group (p operative type, operative time, blood loss, and drainage time were independent predictors of acute surgical site infection following lumbar surgery. In order to reduce the risk of infection following lumbar surgery, patients should be evaluated for the risk factors noted above.

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

    Objective This study aims to analyze the clinical and endoscopic presentations of upper gastrointestinal bleeding (UGIB) in the Chinese children. Methods A 10-year retrospective study was made on children with UGIB and undertaken esophagogastroduodenoscopy (EGD) from 4 tertiary referral centers in China. Results Of the 1218 children studied, the bleeding source was found in 76.4%. Erosive gastritis was the most common endoscopic finding (33.5%), followed by duodenal ulcer (23.2%). The proportion of erosive gastritis decreased with age (correlation coefficient = -0.787), and duodenal ulcer increased with age (correlation coefficient = 0.958). The bleeding source was more likely to be determined in children having EGDs within 48 hours (80.6% vs 67.9%). Conclusions In Chinese children with UGIB, erosive gastritis and duodenal ulcer were the leading causes, and their proportions varied with age. EGDs performed within 48 hours may improve the possibility of finding the source of bleeding. © The Author(s) 2015.

    To examine medium- to long-term orthodontic treatment stability and its possible association with certain variables. In a retrospective longitudinal study of 70 postretention patients, the Peer Assessment Rating (PAR) index was measured at the start (T1) and end (T2) of treatment and between 4 and 10 years afterwards (T3). The stability was considered absolute when the T2 and T3 values were identical and relative when the difference was within the ±5 range. Among the 70 patients, 65.8% were female and 34.2% were male. Their mean age was 14.5 years. The mean treatment length was 2.4 years. The mean retention phase was 3.3 years. The mean pre- and posttreatment PAR scores were 29.8 (T1) and 6.3 (T2). The mean T1-T2 difference was 23.6. The mean T2-T3 difference was -0.39. Within the study, 7.1% presented absolute stability and 68.6% presented relative stability. Lower anterior segment alignment and overbite were the most unstable occlusal features and tended to worsen. Fixed retainer (odds ratio [OR] 0.31; 95% confidence interval [CI] 0.10-0.98) as a protective factor and years without retention (OR 1.32; 95% CI 1.03-1.68) as a risk factor are predictor variables of instability in the case of lower anterior segment alignment. The PAR value at the end of treatment (OR 1.29; 95% CI 1.08-1.54) and extractions (OR 4.76; 95% CI 1.05-21.6) before treatment are predictors for midline instability.

    A retrospective analysis of oral cysts that were seen over an 11-year period in children at a dental institution in Nigeria was carried out. In general, oral cysts accounted for only 2.6% of the total biopsied lesions during the period under review. The most common oral cysts were the mucous retention cysts, the gingival cysts of infants and the dentigerous cyst. The commonest sites were the maxilla, the mandible and the floor of the mouth respectively and there was no significant difference in sex preference. Most of the cases were seen in the age group 11-16 years while the least was in the group aged 6-10 years.

    To assess the efficacy and safety of a weekly oral cycling antibiotic (WOCA) strategy to prevent UTI in women. We performed a monocentric, comparative, retrospective, cross-sectional study on pregnant women under clean intermittent self catheterization between January 2008 and December 2014. WOCA consisted the administration of a single-dose antibiotic, alternating antibiotic A and B once every 2 weeks, according to previous urine cultures. Twenty-five women carried out 30 pregnancies. Thirteen pregnancies (43.3%) were in the WOCA group (WCG) strategy and 17 were in the non-WOCA group (NWCG) (56.7%). In the 19 (63.3%) pregnancies with urinary tract infection (UTI), 5 (38.4%) were in WCG, 14 (82.3%) were not (P = .023). There were more cystitis in NWCG (76.5% vs 23.1% P = .009) but more colonization in WCG (46.2% vs 5.8% P = .025). UTIs were due to Escherichia coli, Enterobacter cloacae, and Klebsiella pneumoniae. There was a nonsignificant increase in preterm birth in NWCG (35.3% vs 7.7% P = .10), no small for gestational age neonates, and no significant difference for the mode of delivery, birthweight, and neonatal outcome. According to our result, WOCA seems safe and effective on symptomatic UTI frequency and could be promoted to help physicians to manage specific risks in pregnancy. Copyright © 2016 Elsevier Inc.

    2011-01-01

    Full Text Available Objectives The purpose of this retrospective study was to evaluate the success rate of intentionally replanted mandibular second molar with C-shaped canal configurations and to access the impact of preoperative periapical lesion on the success of intentional replantation procedure. Materials and Methods This retrospective chart review study evaluated 52 intentionally replanted mandibular second molar teeth treated at Seoul National University Dental Hospital Department of Conservative Dentistry from January 2005 to December 2007. Seventeen teeth were lost for the follow-up, and another 6 teeth did not meet inclusion criteria of C-shaped root canal configurations. Healing outcome such as success, uncertain healing, and failure after follow-up was evaluated by clinical criteria and radiographs. Results The overall success rate was 72.4% for the 29 intentionally replanted C-shaped mandibular second molars. The success rate of replanted teeth with preoperative periapical lesions was similar to that of replanted teeth which have no periapical lesions. Conclusions Therefore, root canal treatment failure on C-shaped mandibular second molar can be predictably treated by intentional replantation regardless of the presence of periapical lesion.

    Impingement of the ilio-psoas tendon on the acetabular component is a cause of pain after total hip arthroplasty (THA). Studies of cup revision for ilio-psoas impingement (IPI) are scarce and limited in size. We therefore conducted a large multicentre retrospective study with the following objectives: to assess the effectiveness of cup replacement in resolving the impingement syndrome, to determine the frequency and nature of complications after cup revision for IPI, and to identify pre-operative factors associated with good outcomes of cup revision for IPI. Cup revision is effective in resolving the pain due to IPI in selected patients. This retrospective multicentre study included 46 patients who underwent cup revision because of IPI. Before the revision, 38 (83%) patients had prominence of the anterior cup rim (mean, 9.9±4.5mm (range, 2-22mm) by radiography and 35 (76%) had cup malposition (anteversion50°). Mean follow-up was 21months (range, 6months to 6 years) and no patient was lost to follow-up. Outcomes at last follow-up were assessed based on the Oxford Hip Score (OHS), patient satisfaction index, complications, and revisions. At last follow-up, 39 (85%) patients were satisfied with the revision procedure, a significant improvement versus baseline was noted in the OHS (mean, 43±6; range, 25-48; P<0.001), and 41 patients were free of pain during hip flexion (P<0.001 versus baseline). Complications occurred in 3 (6.5%) patients, but only one complication was severe (deep infection). Recurrent groin pain was reported by 4 (8.7%) patients at last follow-up. None of the factors studied predicted the outcome of revision surgery. Cup revision for IPI after THA is effective in relieving the groin pain in 80% of patients with anterior cup rim prominence and/or cup malposition. However, complications can occur. Tenotomy may be preferable when the diagnosis is in doubt and/or cup position is acceptable. IV, retrospective observational study. Published by Elsevier

    Anaemia in pregnant women is a public health problem, especially in developing countries. The aim of this study was to assess the prevalence and related risk factors of anaemia during pregnancy in a large multicentre retrospective study (n = 44,002) and to determine the adverse pregnancy outcomes in women with or without anaemia. The study is a secondary data analysis of a retrospective study named "Gestational diabetes mellitus Prevalence Survey (GPS) study in China". Structured questionnaires were used to collect socio-demographic characteristics, haemoglobin levels and pregnancy outcomes from all the participants. Anaemia in pregnancy is defined as haemoglobin anaemia and associated adverse pregnancy outcomes. The overall prevalence of anaemia was 23.5%. Maternal anaemia was significantly associated with maternal age ≥ 35 years (AOR = 1.386), family per capita monthly incomepregnancy BMI pregnancy outcomes, including GDM, polyhydramnios, preterm birth, low birth weight (anaemia than those without. The results indicated that anaemia continues to be a severe health problem among pregnant women in China. Anaemia is associated with adverse pregnancy outcomes. Pregnant women should receive routine antenatal care and be given selective iron supplementation when appropriate.

    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.

    Bronchiectasis is characterized by abnormal, permanent and irreversible dilatation of the bronchi, usually responsible for daily symptoms and frequent respiratory complications. Many causes have been identified, but only limited data are available concerning the association between bronchiectasis and renal transplantation. We conducted a retrospective multicenter study of cases of bronchiectasis diagnosed after renal transplantation in 14 renal transplantation departments (French SPIESSER group). Demographic, clinical, laboratory and CT scan data were collected. Forty-six patients were included (mean age 58.2 years, 52.2 % men). Autosomal dominant polycystic kidney disease (32.6 %) was the main underlying renal disease. Chronic cough and sputum (50.0 %) were the major symptoms leading to chest CT scan. Mean duration of symptoms before diagnosis was 1.5 years [0-12.1 years]. Microorganisms were identified in 22 patients, predominantly Haemophilus influenzae. Hypogammaglobulinemia was observed in 46.9 % patients. Bronchiectasis was usually extensive (84.8 %). The total bronchiectasis score was 7.4 ± 5.5 with a significant gradient from apex to bases. Many patients remained symptomatic (43.5 %) and/or presented recurrent respiratory tract infections (37.0 %) during follow-up. Six deaths (13 %) occurred during follow-up, but none were attributable to bronchiectasis. These results highlight that the diagnosis of bronchiectasis should be considered in patients with de novo respiratory symptoms after renal transplantation. Further studies are needed to more clearly understand the mechanisms underlying bronchiectasis in this setting.

    Full Text Available Background. The aim of this study was to assess the association between herbal medication and OHSS. Methods. This retrospective cohort study was conducted with 101 polycystic ovary syndrome patients. 66 patients took conventional pharmacological medications and 35 took herbal medications. Data were analyzed by statistical test including Fisher’s Exact and binominal logistic regression. P<0.05 was considered significant. Results. Of the 101 females, 53 were married and 48 were single. There was no significant association between the groups in marriage. No significant association was found in mean age between the two groups (23.9 ± 5.8 years in the control group versus 26.3 ± 6.7 years in the case group. There was a significant difference between the two groups .After adding the dependent (OHSS prevalence and independent (marriage and group variables into the model, the Hosmer-Lemeshow test showed suitability. Variances analyzed with this model ranged between 29.4% and 40.7%. Conclusion. The indiscriminate use of herbs is correlated with OHSS. Because patients increasingly consume herbs, they should be aware of potential side effects. However, appropriate dosages of herbs could be obtained for use instead of conventional treatments, which often have side effects.

    2008-07-01

    The aim of the study was to compare historical features, physical examination findings, and testicular color Doppler ultrasound in pediatric patients with epididymitis compared to testicular torsion and torsion of the appendix testes. A retrospective review of the medical records of 66 boys presenting with clinical aspects of acute scrotum over a 3-year period was performed. Sixty-six patients were included in the study (29 with epididymitis, 8 with testicular torsion and 12 with torsion of the appendix testis, 4 with scrotal abscesses, 5 with scrotal swelling, and 1 with inflamed epididymal cyst). The duration of symptoms ranged from 6 h to 4 days with a peak on the second day. Urine cultures and viral testes were negative in all patients. Color Doppler ultrasound was diagnostic for epididymitis in 28 patients (96.6%). Systemic intravenous antibiotics were given in all 29 patients with epididymitis. No patient showed signs of testicular atrophy in the follow-up. The increasing incidence of epididymitis should question the policy of routine exploration of the acute scrotum in children. The history and physical examination cannot reliably identify those boys who can be managed conservatively. Color Doppler ultrasound is a useful adjunct in the evaluation of the acute scrotum when physical findings are equivocal but it can also be misleading.

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

    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.

    The objective of this study was to examine job separations from supported employment (SE). The aim was to identify the types and nature of separations and precipitating events leading to the separation. A retrospective chart review methodology was utilized. The study was conducted in a metropolitan area in the Southeast United States by a university-based SE program. Participants were 47 SE clients who had been placed into and separated from 67 jobs. Using a coding form, information regarding the type of separation and issues that preceded the separation were recorded. Data were aggregated using descriptive statistics. The largest number of separations was due to termination, followed by resignation and mutual consent of the employer and employee. The mean number of issues leading to the separation was 2.2, ranging from one to five. Only eight positive issues were found (compared to 116 negative and 20 neutral), the most prevalent being entry into an educational or training program. Common negative issues included poor work performance, attendance and punctuality problems, conflicts with the supervisor, and social and behavioral issues. The findings of this study illustrate the need to address job retention issues during the job development process, finding the most appropriate person-job fit and workplace culture for each client. The findings also support the need for vigilant and regular communication between the SE program and employers to intervene quickly when problems arise. Separation from Supported Employment (SE) SE is an evidence-based employment practice that has been shown effective across multiple disability groups. Studying job separations can provide valuable information for improving service. Locating the best person-job fit, as well as frequent contract with employers, can help prevent unnecessary job loss.

    The incidence of ductal carcinoma in situ (DCIS) has increased markedly in recent decades. In the past, mastectomy was the primary treatment for patients with DCIS, but as with invasive cancer, breast-conserving surgery followed by radiation therapy (RT) has become the standard approach. We present the final results of a multi-institutional retrospective study of an Italian Radiation Oncology Group for the study of conservative treatment of DCIS, characterized by a very long period of accrual, from February 1985 to March 2000, and a median follow-up longer than 11 years. A collaborative multi-institutional study was conducted in Italy in 10 Radiation Oncology Departments. A consecutive series of 586 women with DCIS histologically confirmed, treated between February 1985 and March 2000, was retrospectively evaluated. Median age at diagnosis was 55 years (range: 29–84); 32 patients were 40 years old or younger. All women underwent conservative surgery followed by whole breast RT. Irradiation was delivered to the entire breast, for a median total dose of 50 Gy; the tumour bed was boosted in 295 cases (50%) at a median dose of 10 Gy. After a median follow-up of 136 months (range: 16–292 months), 59/586 patients (10%) experienced a local recurrence: invasive in 37 cases, intraductal in 20 and not specified in two. Salvage mastectomy was the treatment of choice in 46 recurrent patients; conservative surgery in 10 and it was unknown in three patients. The incidence of local recurrence was significantly higher in women younger than 40 years (31.3%) (p= 0.0009). Five patients developed distant metastases. Furthermore 40 patients developed a contralateral breast cancer and 31 a second primary tumour in a different site. The 10-year actuarial overall survival (OS) was 95.5% and the 10-year actuarial disease-specific survival (DSS) was 99%. Our results are consistent with those reported in the literature. In particular it has been defined the importance of young age (40

    Abstract NIV adherence ('quantity' of ventilation) has a prognostic impact in amyotrophic lateral sclerosis (ALS). We hypothesized that NIV effectiveness ('quality') could also have a similar impact. NIV effectiveness was evaluated in 82 patients within the first month (M1) and every three months (symptoms, arterial blood bases, and nocturnal pulsed oxygen saturation - SpO2). Kaplan-Meier survival and risk factors for mortality one year after NIV initiation were evaluated. Forty patients were considered 'correctly ventilated' at M1 (Group 1, less than 5% of nocturnal oximetry time with an SpO2NIV effectiveness to correct nocturnal desaturations is an independent prognostic factor.

    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.

    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, PPsoriasis 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.

    2009-01-01

    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 Abstract: The lack of guidelines for bone augmentation procedures might compromise decision making in implantology. The objective of this study was to perform a retrospective study to verify the outcomes of horizontal bone reconstruction in implant dentistry with different types of materials and amounts of native bone in the recipient bed to allow for a new guideline for horizontal bone reconstruction. One hundred preoperative CT scans were retrospectively evaluated and categorized in accordance to horizontal bone defects as presence (Group P or absence (Group A of cancellous bone in the recipient bed. Different approaches were used to treat the edentulous ridge and the outcomes were defined either as satisfactory or unsatisfactory regarding the possibility of implant placement. The percentage distribution of the patients according to the presence or absence of cancellous bone was 92% for Group P and 8% for Group A. In Group P, 98% of the patients had satisfactory outcomes, and the use of autografts had 100% of satisfactory outcomes in this group. In Group A, 37.5% of the patients had satisfactory outcomes, and the use of autografts also yielded 100% of satisfactory outcomes. The use of allografts and xenografts in Group A had 0% and 33.3% of satisfactory outcomes, respectively. Therefore, it seems reasonable to speculate that the presence of cancellous bone might be predictive and predictable when the decision includes bone substitutes. In cases of absence of cancellous bone in the recipient bed, the use of a vitalized graft seems to be mandatory.

    Full Text Available Hanging is violent asphyxial death. The objective of this study is to assess the data of hanging cases. A descriptive-retrospective study was conducted. We studied 244 hanging cases autopsied in Forensic Division, Department of Pathology, Faculty of Medicine Ramathibodi Hospital, Mahidol University, Bangkok, Thailand, between January 2001 and December 2013. The study included 197 men (80.7% and 47 women (19.2%. Their age ranged from 14 to 93 years. Most of these cases were incomplete hanging (83.6%. Features of hanging victims, such as tongue protrusion; congestion of face; petechial hemorrhage of face, conjunctiva, and internal organs; and neck injuries, significantly correlated with complete hanging. The predominant occupation of hanging victims was in the service industry (63.1%. Suicides usually occurred in private homes or apartments (84.8%. A suicide note was found in 6.1% of cases. The most common ligature material used was nylon rope, found in 61.1% of cases. The most underlying diseases of the victims in hanging cases were tuberculosis and human immunodeficiency virus infection, 9 cases each. Blood ethanol levels of 29 cases (11.8% were detected to be higher than 150 mg%. Methamphetamine and benzodiazepine were detected in 5.3% and 3.3% of cases, respectively. This study provides comprehensive baseline data of hanging cases in central Bangkok.

    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.

    Nursing student academic failure is a phenomenon of growing international interest, not only because of its economic impact but also because it negatively affects the availability of future nurses in different healthcare systems. To recruit the students with the highest probability of academic success, an open challenge for universities is to recruit students who have previously demonstrated superior scholastic aptitudes that appear to be associated with a greater likelihood of academic success. Documenting the relationship between the selection methods used when selecting nursing students and academic failure will contribute to the international debate concerning the optimisation of the selection strategies. The principal aim of this study was to investigate the role in predicting nursing student academic success of (1) the upper-secondary diploma grades and (2) the score obtained by students in the nursing degree program admission test. A retrospective observational study was conducted. Five cohorts of nursing students, matriculated in consecutive academic years from 2004 to 2008, in an Italian bachelor's degree program were observed retrospectively. Overall, 61.2% of the 1006 considered students concluded their degree within the legal duration allowed for the nursing degree. Students who failed were those who had lowest grades associated with their upper-secondary diploma coursework (p=0.000) and were male (p=0.000). The grades associated with the upper-secondary diploma coursework, unlike the admission test score, correlates positively with the final degree grade and the average value of degree program examination scores. No correlation was found between the upper-secondary diploma coursework grades and the scores obtained in the test for the nursing degree program admission test (r=-0.037). These results suggest that upper-secondary diploma coursework grades are a parameter that should receive great consideration, especially in cases where there are planned

    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.

    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)

    Isolated paraventricular frontal horn cysts are sometimes encountered on cranial ultrasound examinations of preterm neonates. The etiology and clinical significance of these lesions are unclear. The authors aimed to identify antenatal/intrapartum risk factors associated with the occurrence of these cysts and to assess developmental outcomes of preterm neonates with isolated frontal horn cysts. A retrospective cohort study with matched control design was used. A total of 28 cases were matched for gestation with 56 controls. No antenatal/intrapartum factors were associated with these cysts. At corrected age of 1 year, there was no difference in the mean general quotient between cases and controls (97.75 ± 17.28 vs 94.94 ± 9.86; P = .410). In all, 1 case and no controls had a diagnosis of cerebral palsy and 1 case and 3 controls had general quotients less than 80. The authors conclude that isolated paraventricular frontal horn cysts are benign, with no effect on neurodevelopment.

    ECG-triggered cinematographic studies of the cardiovascular system are hampered by several technical restrictions such as the inability to image end-diastole, ghosting, varying signal intensity, and phase contributions from eddy currents. Retrospective gating may solve these problems, but involves...... of flow pulses. However, by reducing the time window retrospectively gated flow measurements were in good agreement with those that are ECG triggered. When fulfilling the demand of a narrow time window for interpolation, retrospective gating offers several advantages in MR velocity mapping....

    Canine sterile nodular panniculitis (SNP) is an inflammatory disease of the panniculus that is typically managed with immunomodulatory or immunosuppressive treatments. It has been reported to be a cutaneous marker of an underlying systemic disease. To assess the presence or absence of concurrent systemic diseases associated with canine SNP and to document breed predispositions. Thirty nine dogs presented to a veterinary teaching hospital from 1990 to 2012 which met inclusion criteria. Inclusion in this retrospective study required a diagnosis of SNP via histopathological analysis and negative special stains for infectious organisms. Breed distributions of affected dogs were compared to all other dogs examined at this hospital during the study period. Correlations between the histological pattern of panniculitis and the histological presence of dermatitis, clinical presentation of lesions, dog breed and therapeutic outcomes were assessed. Australian shepherd dogs, Brittany spaniels, Dalmatians, Pomeranians and Chihuahuas were significantly over-represented, but correlations between inflammatory patterns of panniculitis and other histological and clinical factors were not identified. Based on the information available in medical records, 32 dogs (82.1%) had no concurrent systemic diseases identified. Four dogs had concurrent polyarthritis, which may be related to SNP through unknown mechanisms. This study identified several novel breed predilections for SNP; it failed to find any clear correlations with associated systemic diseases other than polyarthritis. The histological inflammatory pattern of SNP does not predict therapeutic outcome. © 2015 ESVD and ACVD.

    Aim To determine the prevalence of various malignant oral lesions in the UAE and correlate cases of squamous cell carcinomas with age, gender, site, grade, clinical presentations at the time of diagnosis, and the prevalence of neck metastasis. Materials and methods A multicenter, retrospective study was conducted at four major hospitals in the UAE. The study was based on histopathology reports of biopsies of oral tissues. Results Of the 992 oral biopsy reports retrieved, 147 cases of malignant tumors were found which accounted for 14.9% of the total biopsies. Fifteen different types of malignant lesions were diagnosed, of which oral squamous cell carcinoma (OSCC) was the most prevalent and made up 11.4% of the overall oral biopsies retrieved. The commonest presentation of cancer was ulceration (31.17%), followed by lumps and white lesions. The most common site where the lesions were diagnosed was the tongue (51.9%), followed by the cheeks and lips. OSCC accounted for 77% of all malignancies reported. Neck dissections were conducted in only 20.8% of all OSCC cases diagnosed at Mafraq and Tawam hospitals, of which 43.75% showed evidence of neck metastasis. Conclusion Oral cancer is not an uncommon disease in the UAE. This may mandate more awareness campaigning, including screening procedures for early detection of cancerous lesions and other potentially malignant oral diseases. Elective neck dissections to detect lymph node metastasis should be more routinely performed, in particular for tongue carcinomas because of the early neck involvement potential. PMID:23985381

    When traumatic collateral palmar digital nerve defect occurs, emergency venous grafting is an alternative to the two-step nervous grafting procedure. During the course of a monocentric retrospective study, 12 cases of emergency venous grafting were reviewed by a single independent examiner 11 months, at least, post-intervention. Clinical and functional evaluation was carried out, together with a self-assessment of the results by the patient. Data were compacted using a filtering method and the final result was considered in terms of "good" or "bad". Good result was observed in ten cases out of 12. Bad results were associated with poor sensory recovery in the two other cases. In one of these, the bad result was also related to severe symptoms in cold conditions and a troublesome hyperesthesia. Through a review of the literature, we justify the emergency treatment of nerve defects of the collateral palmar digital nerves with venous grafting. Copyright © 2010 Elsevier Masson SAS.

    Full Text Available Lithium users are offered routine renal monitoring but few studies have quantified the risk to renal health. The aim of this study was to assess the association between use of lithium carbonate and incidence of renal failure in patients with bipolar disorder.This was a retrospective cohort study using the General Practice Research Database (GPRD and a nested validation study of lithium exposure and renal failure. A cohort of 6360 participants aged over 18 years had a first recorded diagnosis of bipolar disorder between January 1, 1990 and December 31, 2007. Data were examined from electronic primary care records from 418 general practices across the UK. The primary outcome was the hazard ratio for renal failure in participants exposed to lithium carbonate as compared with non-users of lithium, adjusting for age, gender, co-morbidities, and poly-pharmacy.Ever use of lithium was associated with a hazard ratio for renal failure of 2.5 (95% confidence interval 1.6 to 4.0 adjusted for known renal risk factors. Absolute risk was age dependent, with patients of 50 years or older at particular risk of renal failure: Number Needed to Harm (NNH was 44 (21 to 150.Lithium is associated with an increased risk of renal failure, particularly among the older age group. The absolute risk of renal failure associated with lithium use remains small.

A modularity analysis is made using smart card data collected in Northern Jutland in Marts and July 2014, and the analysis...... reveals first, that smart card data can be used to identify clusters within flows of public transport passengers in a peripheral region. Second, that the presence of such clusters suggest that public transport should be planned to give the users the possibility of travelling with good connectivity...... and easiness within these clusters. Third, the presence of such clusters in peripheral areas of the monocentric region suggest, that the overall current focus in public transport planning on transport possibilities to and from the central city in monocentric regions is questionable....

    IgM myeloma is a rare hematologic malignancy for which the clinicopathological features and patient outcomes have not been extensively studied. We carried out a multicenter retrospective study in patients with diagnosis of IgM myeloma defined by >10% marrow involvement by monoclonal plasma cells, presence of an IgM monoclonal paraproteinemia of any size, and anemia, renal dysfunction, hypercalcemia, lytic lesions and/or t(11;14) identified by FISH. A total of 134 patients from 20 centers were included in this analysis. The median age at diagnosis was 65.5 years with a male predominance (68%). Anemia, renal dysfunction, elevated calcium and skeletal lytic lesions were found in 37, 43, 19, and 70%, respectively. The median serum IgM level was 2,895 mg dL -1 with 19% of patients presenting with levels >6,000 mg dL -1 . International Staging System (ISS) stages 1, 2, and 3 were seen in 40 (33%), 54 (44%), and 29 (24%) of patients, respectively. The malignant cells expressed CD20 (58%) and cyclin D1 (67%), and t(11;14) was the most common cytogenetic finding (39%). The median overall survival (OS) was 61 months. Higher ISS score was associated with worse survival (P = 0.02). Patients with IgM myeloma present with similar characteristics and outcomes as patients with more common myeloma subtypes. © 2017 Wiley Periodicals, Inc.

  11. Retrospective dosimetry of populations exposed to reactor accident: Chernobyl example, lesson for Fukushima

    2013-01-01

    Follow-up of the Chernobyl accident had included a good deal of retrospective dosimetry and dose reconstruction. Comparison of Chernobyl and Fukushima shows that despite some differences in course and scale of the two accidents, main elements are present in both situations and Chernobyl experience could be quite educative for better understanding and more optimal handling of Fukushima Dai-ichi accident consequences. This paper contains review of dose reconstruction efforts done to date and extensively published in scientific journals and reports. Specifically the following cases are considered: (i) evaluation of individual doses to evacuees; (ii) validation of ecological dosimetric models and ruling out unconfirmed dose rate measurements; dosimetric support of (iii) case–control study of leukemia among Chernobyl clean-up workers (liquidators), and (iv) cohort study of cataracts among liquidators. Due to limited size of this paper the given application cases are rather outlined while more detailed descriptions could be found in relevant publications. Each considered Chernobyl case is commented with respect to possible application to Fukushima Dai-ichi situation. The presented methodological findings and approaches could be used for retrospective assessment of human exposures in Fukushima. -- Highlights: ► Retrospective dosimetry in Chernobyl was applied for evaluation of individual doses to evacuees. ► Retrospective dosimetry in Chernobyl was applied for validation of ecological dosimetric models, rejection dubious dose rate records. ► Retrospective dosimetry in Chernobyl was applied for risk assessment of leukemia among Chernobyl clean-up workers (liquidators). ► Retrospective dosimetry in Chernobyl was applied for study of cataracts among liquidators. ► Experience of dose reconstruction in Chernobyl could be used for retrospective assessment of exposures in Fukushima

    Retrospective recall about children's symptoms is used to establish early developmental patterns in clinical practice and is also utilised in child psychopathology research. Some studies have indicated that the accuracy of retrospective recall is influenced by life events. Our hypothesis was that an intervention: speech and language therapy, would adversely affect the accuracy of parent recall of early concerns about their child's speech and language development. Mothers (n = 5,390) reported on their child's speech development (child male to female ratio = 50:50) when their children were aged 18 or 30 months, and also reported on these early concerns retrospectively, 10 years later, when their children were 13 years old. Overall reliability of retrospective recall was good, 86 % of respondents accurately recalling their earlier concerns. As hypothesised, however, the speech and language intervention was strongly associated with inaccurate retrospective recall about concerns in the early years (Relative Risk Ratio = 19.03; 95 % CI:14.78-24.48). Attendance at speech therapy was associated with increased recall of concerns that were not reported at the time. The study suggests caution is required when interpreting retrospective reports of abnormal child development as recall may be influenced by intervening events.

    Waterpipe smoking may increasingly account for unintentional carbon monoxide poisoning, a serious health hazard with high morbidity and mortality. We aimed at identifying waterpipe smoking as a cause for carbon monoxide poisoning in a large critical care database of a specialty care referral center. This retrospective cohort study included patients with a history of exposure to waterpipe smoking and carbon monoxide blood gas levels >10% or presence of clinical symptoms compatible with CO poisoning admitted between January 2013 and December 2016. Patients' initial symptoms and carbon monoxide blood levels were retrieved from records and neurologic status was assessed before and after hyperbaric oxygen treatment. Sixty-one subjects with carbon monoxide poisoning were included [41 males, 20 females; mean age 23 (SD ± 6) years; range 13-45] with an initial mean carboxyhemoglobin of 26.93% (SD ± 9.72). Most common symptoms included syncope, dizziness, headache, and nausea; 75% had temporary syncope. Symptoms were not closely associated with blood COHb levels. CO poisoning after waterpipe smoking may present in young adults with a wide variability of symptoms from none to unconsciousness. Therefore diagnosis should be suspected even in the absence of symptoms.

    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.

    Our objective was to investigate whether pulmonary tuberculosis (PTB) can be predicted from features of a targeted medical history and basic laboratory investigations in immigrants. A retrospective cohort of 391 foreign-born adults referred to the Edmonton Tuberculosis Clinic (Edmonton, AB, Canada) was studied using multiple logistic regression analysis to predict PTB. Seven characteristics of disease were used as explanatory variables. Cross-validation assessed performance. Each predictor was tested on two outcomes: "culture-positive" and "smear-positive". Receiver operating characteristic (ROC) curves were generated and the area under the ROC curve (AUC) was quantified. Symptoms, subacute duration of symptoms, risk factors for reactivation of latent TB infection and anaemia were all associated with a positive culture (adjusted OR 1.79, 2.24, 1.72 and 2.28, respectively; p<0.05). Symptoms, inappropriate prescription of broad-spectrum antibiotics and a "typical" chest radiograph were associated with smear-positive PTB (adjusted OR 2.91, 1.55 and 12.34, respectively; p<0.05). ROC curve analysis was used to test e ach model, yielding AUC=0.91 for the outcome "culture-positive" disease and AUC=0.94 for the outcome "smear-positive" disease. PTB among the foreign-born can be predicted from a targeted medical history and basic laboratory investigations, raising the threshold of suspicion in settings where the disease is relatively rare.

  16. Is dream recall underestimated by retrospective measures and enhanced by keeping a logbook? An empirical investigation.

    Science.gov (United States)

    Aspy, Denholm J

    2016-05-01

    In a recent review, Aspy, Delfabbro, and Proeve (2015) highlighted the tendency for retrospective measures of dream recall to yield substantially lower recall rates than logbook measures, a phenomenon they termed the retrospective-logbook disparity. One explanation for this phenomenon is that retrospective measures underestimate true dream recall. Another explanation is that keeping a logbook tends to enhance dream recall. The present study provides a thorough empirical investigation into the retrospective-logbook disparity using a range of retrospective and logbook measures and three different types of logbook. Retrospective-logbook disparities were correlated with a range of variables theoretically related to the retrospective underestimation effect, and retrospective-logbook disparities were greater among participants that reported improved dream recall during the logbook period. These findings indicate that dream recall is underestimated by retrospective measures and enhanced by keeping a logbook. Recommendations for the use of retrospective and logbook measures of dream recall are provided. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim of this retrospective study was to investigate whether self-reported allergy to penicillin may contribute to a higher rate of postsurgical infection and implant failure. This retrospective, non-interventional, open cohort study reports on implant survival and infection complications of 5,576 implants placed in private practice by one periodontist, and includes 4,132 implants that were followed for at least 1 year. Logistic regression was applied to examine the relationship between self-reported allergy to penicillin and implant survival, while controlling for potential confounders such as smoking, implant site, bone augmentation, loading protocol, immediate implantation, and bone level at baseline. The cumulative survival rate (CSR) was calculated according to the life table method and the Cox proportional hazard model was fitted to data. Out of 5,106 implants placed in patients taking penicillin it was found that 0.8% failed, while 2.1% failed of the 470 implants placed for patients with self-reported allergy to penicillin (P = .002). Odds of failure for implants placed in penicillin-allergic patients were 3.1 times higher than in non-allergic patients. For immediate implant placement, penicillin-allergic patients had a failure rate 10-times higher than the non-allergic cohort. Timing of implant failure occurring within 6 months following implantation was 80% in the penicillin-allergic group versus 54% in the non-allergic group. From the 48 implant sites showing postoperative infection: penicillin-allergic patients had an infection rate of 3.4% (n = 16/470) versus 0.6% in the non-allergic group (n = 32/5,106) (P penicillin allergy was associated with a higher rate of infection, and primarily affected early implant failure.

    Patients with visceral crisis from luminal metastatic breast cancer (mBC) are often treated with palliative chemotherapy. No studies have analyzed the aggressiveness of the care in visceral crisis from luminal mBC patients. The objective of this study was to assess practices in this setting in a university medical oncology department. This retrospective study included all patients who were managed for luminal mBC between January 2013 and April 2016. The analysis focused on the characteristics of the patients, the modalities of cancer treatment and delays between visceral crisis and death. Thirty-five patients pre-treated with two hormonal therapy lines were enrolled retrospectively. Worse performance status and a higher proportion of severe organ dysfunction for luminal mBC were observed among patients with visceral crisis. Sixty-five percent of patients received cytotoxic treatment. One cycle of chemotherapy was administrated in the majority of patients. Palliative care was performed in 35% of patients. Chemotherapy did not have any significant effect on patient outcome in the present study. The mean time between visceral crisis and death was 4.7 weeks (standard deviation = 1.9). Our study showed that visceral crisis in patients with luminal mBC is a complex problem. We need more comprehension of molecular pathogenesis to visceral crisis disease to propose efficacious treatments for these patients and to identify subgroup of patients who need chemotherapy followed by maintenance endocrine therapy.

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

    Full Text Available Some of the endocrinologic diseases, especially Acromegaly, Cushing and Pheochromocytoma have multiple effects on blood glucose metabolism and regulation in non-diabetic patients. In this retrospective survey, records of patients of Tehran Medical Sciences University hospitals have been reviewd. Of 124 Acromegals, GTT was performed for 51 patients, being impaired in 18%. To evaluate diabetes, FBS and BS of 90 patients were checked, overt diabetes was detected in 27%. Among 90 Cushing patients, blood glucose was checked in 60 cases, 47% of these patients had levels above the normal range, and 39% had glucosuria. Among 80 Pheochromocytoma patients, 16 cases (26.5% had overt diabetes. In comparison with other studied, we have obtained a little different results concerning diabetes and impaired GTT prevalence

    Chronic inflammatory conditions, such as psoriasis, may pose an increased risk of cancer due to impaired immunosurveillance resulting from chronic inflammation and immunosuppressive medications. To compare the risk of non-melanoma skin cancer (NMSC) in a retrospective cohort of 72,739 psoriasis patients and 25,956 non-dermatological patients. A record linkage was performed for data on hospitalizations, and the occurrence of NMSC was compared by computing the relative risk (RR) and modelled using multiple logistic regression. Overall, the occurrence of NMSC was 9.6‰ (95% CI: 8.9-10.3‰) in psoriasis patients and 19.6‰ (95% CI: 18.0-21.4‰) in non-dermatological patients (RR = 0.49; 95% CI: 0.44-0.55). The simultaneous adjustment for gender, age, and phototherapy yielded a RR of 0.84 (95% CI: 0.75-0.95). With regards to phototherapy, the occurrence of NMSC was significantly higher among psoriasis patients who underwent phototherapy relative to those who did not (27.0‰ vs. 9.3‰). In this large retrospective study, we found that patients with psoriasis had a 16% lower probability of having NMSC when compared to a group of non-dermatological patients. Further studies, preferably with a prospective longitudinal design to collect more precise data, are needed to corroborate our findings.

    People with serious mental illness (SMI) exhibit a high prevalence of cardiovascular diseases. Mental health services have a responsibility to address poor physical health in their consumers. One way of doing this is to conduct metabolic monitoring (MM) of risk factors for cardiovascular diseases. This study compares two models of MM among consumers with SMI and describes referral pathways for those at high risk of cardiovascular diseases. A retrospective cross-sectional comparison design was used. The two models were: (1) MM integrated with case managers, and (2) MM integrated with case managers and specialist roles. Retrospective data were collected for all new episodes at two community mental health services (CMHS) over a 12-month period (September 2012 - August 2013). A total of 432 consumers with SMI across the two community mental health services were included in the analysis. At the service with the specialist roles, MM was undertaken for 78% of all new episode consumers, compared with 3% at the mental health service with case managers undertaking the role. Incomplete MM was systemic to both CMHS, although all consumers identified with high risk of cardiovascular diseases were referred to a general practitioner or other community based health services. The specialist roles enabled more varied referral options. The results of this study support incorporating specialist roles over case manager only roles for more effective MM among new episode consumers with SMI.

    Retrospective dosimetry is one of the most important tools of accidental dosimetry for dose estimation when dose measurement was not planned. In the affected area many objects can be applied as natural dosimeters. The paper discusses our recent investigations on various electronic components and common salt (NaCl) having useful thermoluminescence (TL) properties. Among materials investigated the electronic components of cell phones seem promising for retrospective dosimetry purposes, having high TL responses, proper glow curve peaks and the intensity of TL peaks vs. gamma dose received provided nearly linear response in the dose range of 10 mGy–1.5 Gy. - Highlights: ► Electronic components and common salt were investigated for accidental and retrospective dosimetry. ► SMD resistors seem promising for retrospective dosimetry purposes. ► Table salt can be used effectively for accidental dosimetry purposes, as well.

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

    To consider the effectiveness of early treatment using one mixed-dentition approach to the correction of moderate and severe Class II malocclusions. Three groups of Class II subjects were included in this retrospective study: an early treatment (EarlyTx) group that first presented at age 7 to 9.5 years (n = 54), a late treatment (LateTx) group whose first orthodontic visit occurred between ages 12 and 15 (n = 58), and an untreated Class II (UnTx) group to assess the pretreatment comparability of the two treated groups (n = 51). Thirteen conventional cephalometric measurements were reported for each group and Class II molar severity was measured on the study casts of the EarlyTx and LateTx groups. Successful Class II correction was observed in approximately three quarters of both the EarlyTx group and the LateTx group at the end of treatment. EarlyTx patients had fewer permanent teeth extracted than did the LateTx patients (5.6% vs 37.9%, P < .001) and spent less time in full-bonded appliance therapy in the permanent dentition than did LateTx patients (1.7 ± 0.8 vs 2.6 ± 0.7years, P < .001). When supervision time is included, the EarlyTx group had longer total treatment time and averaged more visits than did the LateTx group (53.1 ± 18. 8 vs 33.7 ± 8.3, P < .0001). Fifty-five percent of the LateTx extraction cases involved removal of the maxillary first premolars only and were finished in a Class II molar relationship. EarlyTx comprehensive mixed-dentition treatment was an effective modality for early correction of Class II malocclusions.

    This retrospective study focused on the frequency of tooth loss due to periodontal abscess among 42 patients who were treated by a single clinician over a 5- to 29-year period. A total of 114 patients were selected from the active periodontal recall schedule of a single periodontist at The University of Iowa College of Dentistry. The criteria for inclusion in the study included having a history of moderate to advanced periodontitis, being on 3 to 6 month recall periodontal maintenance care, and completion of active periodontal therapy prior to October 1987. Other parameters evaluated were age; gender; number of teeth present and missing at the initial, reevaluation, and last periodontal recall visit; initial periodontal prognosis; furcation involvement; non-surgical and surgical periodontal therapy; and reasons for tooth loss. Patients were grouped according to the number of teeth lost following active periodontal treatment into well-maintained (0 to 3), downhill (4 to 9), and extreme downhill (10 to 23) groups. Forty-two of the 114 patients were identified as having one or more periodontal abscesses. A total of 109 teeth were affected by periodontal abscess of which 49 (45%) teeth were lost and 60 (55%) were successfully maintained over an average of 12.5 years (5 to 29 years). More furcated teeth were lost than nonfurcated teeth and teeth given a hopeless prognosis were lost more consistently than those given a questionable prognosis in all groups. The frequency of periodontal abscess and tooth loss per patient was greater in the downhill and extreme downhill response groups than the well-maintained group. This suggests that teeth with a history of periodontal abscess can be treated and maintained for several years.

    Full Text Available Cattle and poultry enterprises are among the major contributors to food security and socioeconomic empowerment of households in Uganda. However, various diseases constrain their productivity. A two-year retrospective study between April 2012 and March 2014 was conducted using records for cattle and poultry diseases diagnosed at the Central Diagnostic Laboratory (CDL to determine prevalent diseases in Uganda. The laboratory received 836 samples from poultry (36.3% and cattle (63.7%. Of the 836 samples, 47.5% had a definitive diagnosis of disease causation. Most of the cattle and poultry diseases diagnosed were protozoan diseases (39.3% followed by bacterial (21.4%, viral (17.1%, helminthiasis (11.1%, nutritional diseases (4% and others (7.1%. For poultry, viral diseases (29.5% and protozoan diseases (27.1% especially newcastle disease (44.3% and coccidiosis (100% respectively, were the most diagnosed. While for cattle, hemo-protozoan parasites (52.1% were the most prevalent, of which 92.9% were east coast fever infection. Bacterial infection (20.5% in cattle were the second most diagnosed diseases and mastitis was the most diagnosed (46.2%. In summary, coccidioisis, collibacillosis, newcastle disease, gumboro disease, and avian helminthiasis were the most prevalent poultry diseases while in cattle, east coast fever, helminthiasis, mastitis, brucellosis and rabies were the most frequently diagnosed diseases. This study has identified the major diseases that hinder poultry and cattle production in Uganda. The data generated by CDL could be used for surveillance, monitoring and designing strategic interventions for control of poultry and cattle diseases in Uganda.

    Full Text Available Objective: To report clinical findings and treatments for dogs with supraspinatus tendinopathy (ST.Background: ST is a term used to describe tears, calcifying tendinopathy, tendinosis and/or injuries in and around the tendon of the supraspinatus muscle, and is a cause of forelimb lameness, especially in sporting and performance dogs.Evidentiary value: This is a retrospective study of 327 dogs diagnosed with ST.Methods: Medical records (2006 to 2013 were reviewed for history, signalment, prior treatments, physical examination findings, diagnostic imaging and arthroscopic findings, concurrent shoulder and elbow pathologies, and treatments performed.Results: Dogs aged 4 months to 14 years (average 6.5 years; median 6 years were diagnosed with ST. Performance and sporting dogs were 39.4% of the population, with 58.1% of them being agility dogs. Pain was elicited on palpation of the supraspinatus tendon in 49.3% of dogs. Shoulder radiographs in 283 dogs showed mineralisation in 13% of cases. MRI of the shoulder was performed in 31 cases and revealed findings indicative of ST, including hyperintensity of signal on T1 weighted image (or “spin-lattice” and Short T1 Inversion Recovery (STIR sequences of the supraspinatus tendon at its insertion on the greater tubercle and mineralisation of the supraspinatus tendon. Common ultrasonographic findings included increased tendon size (76%, irregular fibre pattern (74%, and non-homogeneous echogenicity (92.5%. The most common findings on shoulder arthroscopy were supraspinatus bulge (82.2% and subscapularis pathology (62.4%. Elbow pathology was recorded in 54.5% of dogs. Treatment outcomes showed 74.6% of dogs failed to respond to non-steroidal anti-inflammatory drugs (NSAID and 40.8% failed to respond to rehabilitation. Conclusions: These findings suggest concurrent shoulder and/or elbow pathology is not uncommon in dogs with ST. Further, ST often fails to respond to NSAID therapy and rehabilitation

    This retrospective study tests if runners who habitually forefoot strike have different rates of injury than runners who habitually rearfoot strike. We measured the strike characteristics of middle- and long-distance runners from a collegiate cross-country team and quantified their history of injury, including the incidence and rate of specific injuries, the severity of each injury, and the rate of mild, moderate, and severe injuries per mile run. Of the 52 runners studied, 36 (69%) primarily used a rearfoot strike and 16 (31%) primarily used a forefoot strike. Approximately 74% of runners experienced a moderate or severe injury each year, but those who habitually rearfoot strike had approximately twice the rate of repetitive stress injuries than individuals who habitually forefoot strike. Traumatic injury rates were not significantly different between the two groups. A generalized linear model showed that strike type, sex, race distance, and average miles per week each correlate significantly (P strike have significantly higher rates of repetitive stress injury than those who mostly forefoot strike. This study does not test the causal bases for this general difference. One hypothesis, which requires further research, is that the absence of a marked impact peak in the ground reaction force during a forefoot strike compared with a rearfoot strike may contribute to lower rates of injuries in habitual forefoot strikers.

    There are minimal data on the use of electroconvulsive therapy (ECT) in adolescents from India. The present study aimed to evaluate the clinical profile and effectiveness of ECT in adolescents (aged 13-18 years). A retrospective chart review was carried out to identify adolescents (aged 13-18 years) who had received ECT during the period 1999-2011. During the study period, 39 such patients received ECT; complete records of 25 patients were available. Details regarding their sociodemographic, clinical, and treatment data were extracted from these records for the present study. During the study period, 658 patients received ECT, of which 39 were aged 18 or younger (5.9%). Schizophrenia (n = 14; 56%) was the commonest diagnosis for which ECT was used in adolescents, followed by depression (n = 3; 12%). Catatonic symptoms (n = 17; 68%) were the most common symptoms among these subjects. Electroconvulsive therapy was considered as a treatment of choice taking the clinical picture account in about three fourths of the patients (n = 19; 76%). The mean (SD) numbers of ECTs administered per patient were 10.1 (4.87) (range, 2-21). The mean (SD) response rate to ECT was 76% (23.3%) (range, 31%-100%). Response rates according to diagnosis were the following: 76.3% for schizophrenia, 87.2% for depression, 81.8% for psychosis (not otherwise specified), and 77.7% for acute and transient psychosis. Response rate in patients with catatonia was 91.6%. Prolonged seizures, nausea and vomiting, and headache were reported in 2 cases each. Electroconvulsive therapy is used less frequently in children and adolescents compared to the older patients. This study shows that ECT is effective in the treatment of severe psychiatric disorders in adolescents and is associated with the same frequency of adverse effects as the adults.

    Despite growing evidence from longitudinal studies of a link between early-life stress and the development of asthma, very few of these examine one of the most severe types of early-life stress: childhood maltreatment. Cross-sectional studies on this topic have relied on retrospective self-reports of maltreatment. This study investigates associations between childhood maltreatment indicated by child protection agency records versus self-reports and lifetime asthma diagnosis in young adults, adjusting for socioeconomic status and mental disorders. A nationally representative general population survey of DSM-IV mental disorders in New Zealand (n = 12,992) obtained information on lifetime diagnoses of chronic physical conditions. Information from a subsample of survey respondents aged 16 to 27 years (n = 1413) was linked with a national child protection database to identify respondents with a history of agency involvement, which was used as a proxy for childhood maltreatment. Retrospective reports of maltreatment were also obtained. Child protection agency history was associated with elevated odds (odds ratio = 2.88 [95% confidence interval = 1.7-4.74]) of a lifetime diagnosis of asthma. After adjusting for a variety of indicators of socioeconomic status, lifetime mental disorders, lifetime smoking, and body mass index, this association remained significantly elevated (odds ratio = 2.26 [95% confidence interval = 1.33-3.83]). Retrospectively self-reported maltreatment in childhood was not associated with asthma. Childhood maltreatment was associated with elevated odds of asthma diagnosis. These findings are consistent with the possibility that early-life stress may be one of the environmental factors that increase the risk of asthma in genetically vulnerable individuals.

    Bone scintigraphy is a very sensitive diagnostic tool to detect elevated bone metabolism. In cases of fractures and fissure fractures, the radiopharmaceutical uptake in the bone is said to be increased within a few hours after the injury. In this retrospective study, the scintigraphic uptake characteristics at the fracture site of 36 horses with radiographically confirmed fractures or fissure fractures were evaluated. Uptake ratios between the fracture region and adjacent normal bone or soft tissue activity respectively were calculated and compared to different anamnestic and radiographic data. The overall sensitivity of bone scintigraphy was 94.4% (34 positive cases out of 36). In the 36 horses, no correlation between the age of the fracture and the radiopharmaceutical uptake was found. However, there seems to be a lack of sensitivity in early detection of equine pelvic fractures when a standing bone scintigraphy examination protocol is used.

    Full Text Available Abstract Background Hemodiafiltration (HDF, as a convective blood purification technique, has been associated with favorable outcomes improved phosphate control, removal of middle-molecules such as Beta2-microglobulin and the occurrence of intradialytic hypotension (IDH as compared to diffusive techniques. The aim of this retrospective cohort study in dialysis patients receiving HDF in one urban dialysis facility in Mexico City was to investigate the occurrence of IDH during HDF treatments with varying convective volume prescriptions. Methods Subjects were stratified into equal groups of percentiles of convective volume prescription: Group 1 of 0 to 7.53 liters, group 2 of 7.54 to 14.8 liters, group 3 of 14.9 to 16.96 liters, group 4 of 16.97 to 18.9 liters, group 5 of 21 to 19.9 liters and group 6 of 21.1 to 30 liters. Logistic Regression with and without adjustment for confounding factors was used to evaluate factors associated with the occurrence of IDH. Results 2276 treatments of 154 patients were analyzed. IDH occurred during 239 HDF treatments (10.5% of all treatments. Group 1 showed 31 treatments (8.2% with IDH whereas group 6 showed IDH in only 15 sessions (4% of all treatments. Odds Ratio of IDH for Group 6 was 0.47 (95% CI 0.25 to 0.88 as compared to Group 1 after adjustment. Conclusions In summary the data of this retrospective cohort study shows an inverse correlation between the occurrence of IDH and convective volume prescription. Further research in prospective settings is needed to confirm these findings.

    Heart failure (HF) is a leading cause of hospitalisation in China, which is experiencing a rapid increase in cardiovascular disease prevalence. Yet, little is known about current burden of disease, quality of care and treatment outcomes of HF in China. The objective of this paper is to describe the study methodology, data collection and abstraction, and progress to date of the China Patient-centered Evaluative Assessment of Cardiac Events 5 Retrospective Heart Failure Study (China PEACE 5r-HF). The China PEACE 5r-HF Study will examine a nationally representative sample of more than 10 000 patient records hospitalised for HF in 2015 in China. The study is a retrospective cohort study. Patients have been selected using a two-stage sampling design stratified by economic-geographical regions. We will collect patient characteristics, diagnostic testing, treatments and in-hospital outcomes, including death and complications, and charges of hospitalisation. Data quality will be monitored by a central coordinating centre and will address case ascertainment, data abstraction and data management. As of October 2017, we have sampled 15 538 medical records from 189 hospitals, and have received 15 057 (96.9%) of these for data collection, and completed data abstraction and quality control on 7971. The Central Ethics Committee at the Chinese National Center for Cardiovascular Diseases approved the study. All collaborating hospitals accepted central ethics committee approval with the exception of 15 hospitals, which obtained local approval by internal ethics committees. Findings will be disseminated in future peer-reviewed papers and will serve as a foundation for improving the care for HF in China.

    Full Text Available Indolent ulcers are superficial corneal ulcers secondary to several changes on the corneal surface. They are frequently observed in middle-aged Boxer dogs, cause pain of acute onset and requires appropriate treatment. Aiming to evaluate the efficacy of clinical managements on the rate of healing of indolent ulcers, a retrospective study was conducted (1997-2008. Results demonstrated that proteinase inhibitors were the most often prescribed medication, and its administration did not interfere on the healing rate, as well as observed in dogs that received 1% atropine, antibiotics and anti-inflammatory drugs. Healing was delayed in dogs administered orally with vitamin C, but the healing process was faster on those dogs that went through corneal debridement/cauterization. In conclusion, to know the various types of treatments seems to be fundamental for the rapid resolution of the disease. It is suggested that debridement/cauterization, administration of proteinase inhibitor eye drops, prophylactic topical antibiotics and oral vitamin C, should be considered as an effective clinical management for indolent ulcers in Boxer dogs.

  5. The retrospective gambler's fallacy

    Full Text Available The gambler's fallacy (Tune, 1964 refers to the belief that a streak is more likely to end than chance would dictate. In three studies, participants exhibited a extit{retrospective gambler's fallacy} (RGF in which an event that seems rare appears to come from a longer sequence than an event that seems more common. Study 1 demonstrates this bias for streaks, while Study 2 does so with single rare events and shows that the appearance of rarity is more important than actual rarity. Study 3 extends these findings from abstract gambling domains into real world domains to demonstrate the generalizability of the effects. The RGF follows from the law of small numbers (Tversky and Kahneman, 1971 and has many applications, from perceptions of the social world to philosophical debates about the existence of multiple universes.

    To evaluate the signalment, clinical signs, treatment, and outcome of dogs with urethral prolapse and identify risk factors associated with prolapse or treatment. Retrospective case series. Dogs (n = 48) with urethral prolapse. Medical records (May 1995-June 2010) from 2 referral centers were reviewed. Retrieved data included signalment, clinical signs, laboratory findings, treatment, complications, results of long-term follow-up. Records from Veterinary Medical Data Base (VMDB) were evaluated to determine odds ratios. Odds ratio for urethral prolapse in English bulldogs compared to all breeds was 366.99 (95% CI: 265.83, 506.65). Of 48 affected dogs, 46 had either resection and anastomosis (43 dogs) or urethropexy (3 dogs). The most common early postoperative complication was hemorrhage (39%); postoperative hemorrhage was less common when a simple continuous pattern was used for resection and anastomosis. Prolapse recurred in 57% of dogs available for long-term follow-up; recurrence was less common in dogs that were administered postoperative butorphanol or acepromazine. Gender was not associated with urethral prolapse or postoperative complications. Urethral prolapse occurs most commonly in English bulldogs. Postoperative hemorrhage and prolapse recurrence may be reduced with use of a simple continuous pattern for urethral anastomosis and by administration of postoperative sedation, respectively. Castration status did not appear to affect prolapse development or outcome. © Copyright 2014 by The American College of Veterinary Surgeons.

    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.

    Full Text Available OBJECTIVES: to analyze when the nursing process began to be used in the public and private healthcare centers of Gipuzkoa (Basque Country, and when both NANDA-I nursing diagnoses and the NIC-NOC terminologies were incorporated into this process. METHOD: a retrospective study was conducted, based on the analysis of nursing records that were used in the 158 studied centers. RESULTS: the specific data provided showed that in Gipuzkoa, the nursing process began to be used in the 1990s. As for NANDA-I nursing diagnoses, they have been used since 1996, and the NIC-NOC terminologies has been used since 2004. CONCLUSION: it was concluded that public centers are the ones which, generally speaking, first began with the nursing methodology, and that in comparison to the United States and Canada, the nursing process started to be used about 20 years later, NANDA-I nursing diagnoses around 15 years later, and the NIC-NOC terminologies, around six years later.

    The aim of the study was to assess the microperimetric consequences of active internal limiting membrane (ILM) peeling during idiopathic epimacular membrane (IEMM) surgery. This retrospective monocentric study included 32 eyes of 31 consecutive patients who underwent IEMM surgery. Internal limiting membrane integrity was assessed by ILM Blue staining after IEMM removal: peeling was spontaneous (Group S) or active (Group A). Preprocedure and postprocedure (1 and 6 months) examinations were performed using visual acuity determination, spectral domain optical coherence tomography and microperimetry. Twenty-two eyes had an "active ILM peeling" and 10 a "spontaneous ILM peeling." Both groups had comparable and significant improvements in visual acuity 6 months after surgery (+1.82 lines [+9 letters] [Group A] and +1.51 lines [+8 letters] [Group S], P peeling has progressively become generalized in IEMM surgery to reduce recurrences. This additional procedure does not change the postoperative visual acuity but increases the development of deeper microscotomas. The real impact on the quality of vision remains unclear. Active ILM peeling in IEMM surgery may be responsible for visual impairment related to its microtraumatic effects.

    Ectodermal dysplasias form a complex, nosologic group of diseases with defects in at least 2 ectodermal structures. A retrospective study of patients with ectodermal dysplasia seen at our department over a period of 19 years (1994-2013) was performed. The study population consisted of 67 patients covering 17 different diagnoses. Forty-five families were identified of which 26 were sporadic cases with no affected family members. In 27 tested families a disease-causing mutation was identified in 23 families. Eleven mutations were novel mutations. To our knowledge, we present the first large ectodermal dysplasia cohort focusing on clinical manifestations in combination with mutational analysis. We recommend a nationwide study to estimate the prevalence of the ectodermal dysplasia and to ensure relevant molecular genetic testing which may form the basis of a national ectodermal dysplasia database.

    The purpose of this retrospective study was to assess performance, together with biological and technical complications, of implant-supported removable partial dentures (ISRPD) in mandibular Kennedy class I situations with implants placed in the anterior or posterior position. 23 subjects with two endosseous implants to support a bilateral-free-ending mandibular removable denture were examined. Eight subjects had implants in the premolar (anterior) region and 15 subjects implants in the molar (posterior) region. Biological and technical complications were recorded from the patients' medical record. Patients filled out a validated questionnaire regarding their appreciation of oral health related quality of life (OHIP-NL49) and a VAS score on overall satisfaction. Over a mean follow-up period of 8 years (median 8 years, range 3-16 years) the cumulative implant survival rate was 91.7% (SE 0.05). Mean peri-implant bone loss was 0.9mm (SD 1.0mm). Scores for bleeding on probing, plaque and mucosal health were generally low, but significantly worse for posteriorly placed implants. Significantly more biological complications occurred in the posterior group (X 2 (1)=3.9; p=0.048). In 65% of the cases no technical complications were registered. Mean overall OHIP score was 16.1 (SD 18.4) and patients were highly satisfied (VAS: 8.4; SD 2.1). Within the limitations of this retrospective study, in case of a Kennedy class I situation in the mandible, an ISRPD is a viable treatment option with a high implant survival rate and satisfied patients after a maximum of 16 years. Technical and biological complications should be anticipated. Anteriorly placed implants performed slightly better. Copyright © 2016 Japan Prosthodontic Society. Published by Elsevier Ltd.

    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.

    Sacubitril, a neprilysin inhibitor in the combination molecule sacubitril/valsartan, slows down degradation of endogenous natriuretic peptides, thereby enhancing their beneficial cardiovascular effects. However, sacubitril might also promote neuronal dysfunction and cognitive impairment in patients with chronic heart failure (CHF) treated with sacubitril/valsartan, due to possible neprilysin inhibition at the level of Central Nervous System. A retrospective cohort study was undertaken to detect the effects exerted by sacubitril/valsartan on cognitive function in CHF patients. The patients' clinical data were examined for information provided in the Mini-Mental State Examination (MMSE), which was routinely administered during clinical visits at two centers from 15 March to 31 October 2017. Patients in the sacubitril/valsartan group had a clinical history of at least 3 months of continuous sacubitril/valsartan administration. The control group comprised CHF patients on conventional therapy not taking sacubitril/valsartan. In the between-group comparison, patients were matched for mean age, educational level, sex, NYHA class, and comorbidities. In the present retrospective study only patients in NYHA class II-III were enrolled. The mean MMSE score was 22.72 ± 2.68 (mean ± standard deviation [SD]) in the sacubitril/valsartan group (n = 51 patients) vs. 21.96 ± 2.73 (mean ± SD) in the control group (n = 51; p = 0.1572, independent samples t-test). Thus, a similar mild-to-moderate impairment in cognitive performance was found in the comparison between the two groups. In our study, we did not find any evidence of the alleged harmful influence of sacubitril/valsartan on cognitive function. Patients taking sacubitril/valsartan for at least 3 months had similar mean MMSE scores to control subjects.

    Accidents are a preventable cause of death. Unfortunately it accounts for a large number of deaths in many societies. In Kuwait, road traffic accidents (RTA) is the leading cause of death in young people. The study investigated the patterns of accidental deaths in Kuwait, one of the Gulf States which incorporates a wide variety of multi-ethnic communities. The study was retrospective from 2003-2009. Data of forensic cases were collected from the general department of criminal evidence (GDCE) in the ministry of interior (MOI).We attempted to find out causes of accidental death and the prevelance of each cause. Furthermore, the relationship of demographic factors (eg. Age, sex, marital status and nationality) with each cause of accidental death in Kuwait were studied. The material of this study constituted a total of 4886 reported accidental deaths referred for Medico-legal examination. Road traffic accidents was by far the most prevalent cause of death (64.6%) followed by fall from height (13.1%). Poisoning and mine explosions were amongst the least common causes. The government of Kuwait needs to take strong measures to promote safety in the workplace and households by educational campaigns.

  1. Bevacizumab Exacerbates Paclitaxel-Induced Neuropathy: A Retrospective Cohort Study.

    Directory of Open Access Journals (Sweden)

    Ayumu Matsuoka

    Full Text Available 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

    Controversy persists as to whether lichen planus pigmentosus and ashy dermatosis are separate clinical entities. This study was conducted to examine the clinicopathological features and treatment outcome of the two conditions. A retrospective medical chart review of all patients who were diagnosed with lichen planus pigmentosus or ashy dermatosis was conducted. The information collected included the participants' age at onset, site of onset, duration of disease, presence of precipitating factors, distribution of disease, pigmentation and presence of symptoms. In patients from whom a biopsy was taken the histopathological reports were included. Altogether 26 patients with ashy dermatosis and 29 with lichen planus pigmentosus were included in the study. Compared with ashy dermatosis, lichen planus pigmentosus had a more localised distribution with a preponderance for facial involvement, compared with the truncal preponderance in ashy dermatosis. Ashy dermatosis tended to have a more stable clinical course than lichen planus pigmentosus, which was more likely to wax and wane. The utility of histopathology in differentiating between the two conditions is low. Ashy dermatosis and lichen planus pigmentosus, as defined in this study, appear to be two separate clinical entities with distinguishable clinical features and natural histories. © 2018 The Australasian College of Dermatologists.

    Abstract Background Aseptic loosening is one of the greatest problems in hip replacement surgery. The rotation center of the hip is believed to influence the longevity of fixation. The aim of this study was to compare the influence of cemented and cementless cup fixation techniques on the position of the center of rotation because cemented cup fixation requires the removal of more bone for solid fixation than the cementless technique. Methods We retrospectively compared pre- and post-operativ...

    Purpose: To seek for the possible factors influencing overall survival (OS) with radiotherapy (RT) for biliary tract cancer. Materials and methods: Data were collected retrospectively from RT database of 31 institutions in Japan. All patients underwent at least external beam RT. The factors influencing OS were investigated. Results: Data of 498 patients were analyzed. Median OS of the 212 patients who underwent surgery was significantly better than that of the 286 patients without surgery (31 vs. 15 months, p < 0.001). The OS for the R0 or R1 resection group was significantly longer than that for the R2 or non-surgery group, as well as for n0 compared to n1 (all p < 0.001). Chemoradiotherapy (CRT), both sequential and concurrent, resulted in a better OS than RT alone for the n1 group (31 vs. 13 months, p < 0.001), and marginally better for the R0/R1 group (p = 0.065; p = 0.054 for concurrent CRT). However, no such benefit was observed for the R2/non-surgical patients. Multivariate analysis identified performance status, clinical stage, and surgery as significant factors. Conclusion: Surgery, especially R0/R1 resection, seemed as the gold standard for treatment of biliary tract cancer including RT, even in the highly heterogeneous population obtained from the multicenter retrospective study. The possibility was shown that CRT yielded better survival benefit especially for n1 patients. We recommend that future prospective trials include an arm of adjuvant CRT at least for n1 and possibly R0/R1 patients

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

    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

    There are problems that are unresolved with regard to the treatment of cases presenting a post-taumatic cervical myelopathy, such as when the surgical indications are not clearly evidence and the proper timing of this surgery. In this regard, the authors have used dynamic MRI to retrospectively analyze the cervical spine of 24 previously treated dynamic MRI cases presenting a subacute myelopathy to determine the efficacy of dynamic MRI as a method of treatment. Dynamic MRI analysis protocol was as follows. For the MR imagings, each patient was placed supine with the neck in the neutral position, after which the neck was set in the extended position. Dynamic changes between the neutral position and extended position images were analyzed by focusing on the following two point: (1) the narrowing of the subarachnoid space in the T2-weighted images and (2) evidence of cord compression in the T1-weighted images. Twelve cases out of 24 were treated conservatively because of a gradual improvement in their myelopathic symptoms. The other 12 cases were treated surgically, because of no improvement in their residual myelopathic symptoms at the time when the dynamic MRI had been performed. In the majority of cases in the surgical group, the narrowing of the subarachnoid space and spinal cord compression were hightened on neck extension, whereas in the conservative group, such findings were minimal. Dynamic MRI also more clearly visualized multiple lesions and the direction of the cord compression. These findings thus provided more detailed information to plan the surgical approach and to estimate the amount of surgical decompression needed. Based on the results of this retrospective study, we thus concluded that surgical treatment appears to benefit subacute cases who show no improvement in their residual myelopathic symptoms and whose dynamic MRI results also demonstrate an increased narrowing of subarachnoid space and a heightened spinal cord compression.

    Dental erosion (DE), one of oral hard tissue diseases, is one of the extraoesophageal symptoms defined as the Montreal Definition and Classification of gastroesophageal reflux disease (GERD). However, no study evaluated the relationship between GERD and oral soft tissues. We hypothesized that oral soft tissue disorders (OSTDs) would be related to GERD. The study aimed to investigate the association OSTDs and GERD. GERD patients (105 cases), older and younger controls (25 cases each) were retrospectively examined for oral symptoms, salivary flow volume (Saxon test), swallowing function (repetitive saliva swallowing test [RSST]), teeth (decayed, missing, and filled [DMF] indices), and soft tissues (as evaluation of OSTDs, gingivitis; papillary, marginal, and attached [PMA] gingival indexes, simplified oral hygiene indices [OHI-S], and inflammatory oral mucosal regions). Clinical histories, which included body mass index [BMI], the existence of alcohol and tobacco use, and bruxism, were also investigated. A P value of bruxism, as an exacerbation factor of periodontal disease, in the GERD patients was significantly more frequent than in either control group (P = 0.041). OSTDs were associated with GERD, which was similar to the association between DE and GERD.

    A common cavity deformity (CCD) is a deformed inner ear in which the cochlea and vestibule are confluent forming a common rudimentary cystic cavity that results in profound hearing loss. There are few studies paying attention to common cavity. Our group is engrossed in observing the improvement of auditory and verbal abilities in children who have received cochlear implantation (CI), and comparing these targets between children with common cavity and normal inner ear structure. A retrospective study was conducted in 12 patients with profound hearing loss that were divided into a common cavity group and a control group, six in each group matched in sex, age and time of implantation, based on inner ear structure. Categories of Auditory Performance (CAP) and speech intelligibility rating (SIR) scores and aided hearing thresholds were collected and compared between the two groups. All patients wore CI for more than 1 year at the Cochlear Center of Anhui Medical University from 2011 to 2015. Postoperative CAP and SIR scores were higher than before operation in both groups (p good as in those without CCD, CI provides benefits in auditory perception and communication skills in these children.

    This study was designed to evaluate the efficacy of exchange transfusion in patients with severe imported falciparum malaria. Twelve patients who met the diagnostic criteria for severe malaria were treated with exchange transfusion 14 times according to a conventional anti-malarial treatment. This study evaluated the efficacy of exchange transfusion for severe imported falciparum malaria. Clinical data of severe imported falciparum malaria patients admitted to the intensive care unit (ICU) of Nantong Third People's Hospital from January 2007 to December 2016 were investigated in this retrospective study. Patients were divided into the intervention group, which received exchange transfusion, and the control group. This study assessed parasite clearance and outcomes of the two groups, and levels of erythrocytes, haemoglobin, platelets, coagulation, liver function, lactate, C-reactive protein, and procalcitonin, before and after exchange transfusion in the intervention group. There was no significant difference in the severity of admitted patients. Exchange transfusion was successfully applied 14 times in the intervention group. Differences in the levels of erythrocytes, haemoglobin and platelets did not reach statistical significance. Exchange transfusion improved coagulation, liver function, lactic acid, C-reactive protein, and procalcitonin. No differences were observed in parasite clearance, ICU and hospital length of stay, in-hospital mortality, and costs of hospitalization between the two groups. Exchange transfusion as adjunctive therapy for severe malaria was observed to be safe in this setting. Exchange transfusion can improve liver function and coagulation and reduce inflammation, but it failed to improve parasite clearance and the outcomes of severe imported falciparum malaria in this case series.

    Borderline tumors of the ovary (BOT) are a distinct entity of ovarian tumors, characterized by lack of stromal invasion. Recent studies postulated that the presence of invasive implants, incomplete staging, fertility sparing surgery and residual tumor after surgery are major prognostic factors for BOT. There are no biomarkers that can predict BOT or the presence of invasive implants. The aim of our study was to assess the value of CA125 and HE4 alone, or within ROMA score for detecting BOT, and for predicting the presence of invasive implants. Retrospective, monocentric study on 167 women diagnosed with BOT or benign ovarian masses. Serum HE4, CA125 levels and ROMA were assessed preoperatively. Due to low number of BOT with invasive implants, we performed an unmatched analysis (consecutive patients) and a matched analysis (according to age and histology) to compare BOT with invasive implants, BOT without invasive implants and benign disease. There were no significant differences in the HE4 and CA125 expressions in the three groups of patients (p = 0.984 and p = 0.141, respectively). The ROC analysis showed that CA125 alone is superior to ROMA and HE4 in discriminating patients with BOT with invasive implants from patients with benign diseases and BOT without invasive implants. A newly established score, ROMABOT, did not perform better than ROMA. The analysis of the matched groups revealed similar results as the analysis of all samples. Both HE4 and CA125 are not reliable biomarkers for the diagnosis of BOT or for predicting the presence of invasive implants.

    A retrospective study was conducted on the use of the ROC (Radial Osteo Compression) soft-tissue anchor in foot and ankle surgery. This article describes how the anchor is deployed, problematic aspects of using the anchor, and complications and success rates associated with the anchor in ankle stabilizations, posterior tibial tendon reconstruction, peroneus brevis tendon reconstruction after fracture of the base of the fifth metatarsal, and detachment and reattachment of the Achilles tendon. The ROC anchor consists of the anchor with nonabsorbable suture attached to the shaft, the deployment handle, and drill bits. The anchor and shaft are snapped into the deployment handle and inserted into the drill hole. Compression of the trigger deploys the anchor into the hole. The ROC anchor was found to be reliable, useful, and relatively easy to deploy, with outcomes similar to those of other soft-tissue anchors.

    Full Text Available As violence in society is increasing in recent years it is an important problem in health institutions as well. Changes in health systems, rising socio-economic levels of people, and changes in expectations for health services led to violence in health sector. This study was conducted for the purpose of examining work place violence against health care workers. This retrospective-descriptive study covers a period from December 2011 to April 2015. 136 notifications about work place violence reported by health workers to quality management unit of a hospital were taken into account. Research findings show that 43,4% of the victims of violence was physicians, 37,5% was nurses and health officers and 19,1% were from other professions. 63,2% of the health workers were women, 36,8% were male. Additionally health workers were exposed to violence by 47.3% of the patients and 52.7% by their relatives. 69.7% of the people applied violence were male and 30.3% were female. 63,2% of the health workers exposed to violence were women, 36,8% were male. According to our results male physicians were exposed to workplace violence more than other workers and this was significant ( χ 2=31,634, p<0,01. When place of violence occurred was investigated it was seen that while most of physicians were exposed to violence in polyclinics, nurses were exposed to violence in inpatient services (χ2=18,231, p<0,01. Male physicians were exposed to verbal violence most. On the other hand nurses experienced both verbal and physical violence (χ2=34,639,p<0.01. Patient relatives applied verbal violence and the others applied physical violence (χ2=22,073, p<0,01. As a result, in order to reduce / prevent violence in work place , it is considered necessary to increase consciousness of patients and their relatives, to increase security measures in health institutions, to provide health workers to report work place violence to management , to improve physical working conditions and

    Full Text Available Flipped classrooms have been successfully used to increase student engagement and support student learning in a range of educational fields, including health education. These advantages for student learning supported implementation of the flipped classroom in introductory sciences and preclinical courses in dental education. We report on a 4-year retrospective study which compared two methods of delivery of a first-year dental anatomy course. The first method used the traditional method, consisting of face to face contact teaching hours, which was compared to a partial flipped classroom, where lecture contact was maintained but practical classes were flipped. A series of online videos demonstrating different practical tasks such as wax carving and tooth identification. An online digital library and online quizzes for self-reflected learning were developed and trialled. Students’ Evaluations of Course (SEC and students’ overall performance in practical and theoretical assessments were used to evaluate the impact on student engagement and success, respectively, after implementation of the modified course offerings. This study evidences the success of the transition to a partially flipped course design. Careful design and consideration of implementation of the flipped classroom method in dental education are recommended to ensure that there is reliable availability of online resources and dedicated teaching staff for construction of resources and delivery of relevant in-class activities.

    Purpose: Current retrospective cardiovascular dosimetry studies are based on a representative patient or simple mathematic phantoms. Here, a process of patient modeling was developed to personalize the anatomy of the thorax and to include a heart model with coronary arteries. Methods and Materials: The patient models were hybrid computational phantoms (HCPs) with an inserted detailed heart model. A computed tomography (CT) acquisition (pseudo-CT) was derived from HCP and imported into a treatment planning system where treatment conditions were reproduced. Six current patients were selected: 3 were modeled from their CT images (A patients) and the others were modelled from 2 orthogonal radiographs (B patients). The method performance and limitation were investigated by quantitative comparison between the initial CT and the pseudo-CT, namely, the morphology and the dose calculation were compared. For the B patients, a comparison with 2 kinds of representative patients was also conducted. Finally, dose assessment was focused on the whole coronary artery tree and the left anterior descending coronary. Results: When 3-dimensional anatomic information was available, the dose calculations performed on the initial CT and the pseudo-CT were in good agreement. For the B patients, comparison of doses derived from HCP and representative patients showed that the HCP doses were either better or equivalent. In the left breast radiation therapy context and for the studied cases, coronary mean doses were at least 5-fold higher than heart mean doses. Conclusions: For retrospective dose studies, it is suggested that HCP offers a better surrogate, in terms of dose accuracy, than representative patients. The use of a detailed heart model eliminates the problem of identifying the coronaries on the patient's CT.

    Full Text Available Abstract Background Nausea and vomiting is a problem for children after neurosurgery and those requiring posterior fossa procedures appear to have a high incidence. This clinical observation has not been quantified nor have risk factors unique to this group of children been elucidated. Methods A six year retrospective chart audit at two Canadian children's hospitals was conducted. The incidence of nausea and vomiting was extracted. Hierarchical multivariable logistic regression was used to quantify risk and protective factors at 120 hours after surgery and early vs. late vomiting. Results The incidence of vomiting over a ten day postoperative period was 76.7%. Documented vomiting ranged from single events to greater than 20 over the same period. In the final multivariable model: adolescents (age 12 to Conclusion The incidence of vomiting in children after posterior fossa surgery is sufficient to consider all children requiring these procedures to be at high risk for POV. Nausea requires better assessment and documentation.

  6. RETROSPECTIVE DATA COLLECTION: CAN STUDENTS REMEMBER?

    2015-01-01

    Full Text Available Abstract: It is not always possible or practical to gather data over a long period of time, and researchers have used retrospective data from questionnaire and interview to gain insights into change over time. There has been little discussion within SLA as to the validity of this data, and it is seemingly accepted at face value. This paper examines both qualitative and quantitative retrospective accounts of changes in self-efficacy, by collecting quantitative questionnaire data over a one-year period, and then asking students to quantitatively recollect their feelings of self-efficacy over that time frame, followed by qualitative description. Results showed that students were able to accurately recollect quantitative data, although there was a noticeable degradation in accuracy with time. Interview data suggested that students were reluctant to admit lack of ability to recall events, and sometimes produced conflicting accounts of events.  This may in part be due to the dual role of teacher and researcher adopted in this study. The implications for researchers and also for teachers are considered.

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

    To examine the effect of malnutrition due to anorexia nervosa (AN) on venous blood gases of adolescents with AN hospitalized for medical stabilization. This retrospective study included 45 adolescents with recent onset (respiratory acidosis (pH 45 mm Hg) was observed in 78% of the patients on admission and only in 35% at discharge (p = .0003). Positive correlations were found between % of weight loss and pCO(2) on admission and between BMI on admission and the delta pCO(2) during hospitalization. Mild respiratory acidosis is common in adolescents with recently diagnosed AN, hospitalized for medical stabilization. Respiratory acidosis improves with bed rest and refeeding. The clinical significance of these findings should be further evaluated. Copyright © 2011 Wiley Periodicals, Inc.

    We retrospectively studied daptomycin use during 2010 at the Bichat-Claude-Bernard teaching-hospital (Paris) to observe the evolution of daptomycin prescriptions. Twenty-one patients were included and several parameters were documented: site of infection, bacterial species involved, reason for daptomycin use, dose and clinical outcome. Ninety-five percent of daptomycin prescritions were off-label and most did not comply with local guidelines. Fifteen of the 21 patients were cured (71%), including 9 patients of the 12 with off-label and off-local recommendation prescriptions (75%). Osteitis and Enterococcus spp endocarditis were the new indications. Daptomycin was increasingly used at higher doses: 52% of our patients were given doses above 6mg/kg. Staphylococcus spp. was the most frequent pathogen responsible for infection is our patients, followed by Enterococcus spp. Daptomycin use is likely to evolve because of its effectiveness in the treatment of osteitis, left-sided and Enterococcus spp. infective endocarditis. It is generally used at higher doses, which are well tolerated. However, therapeutic monitoring needs to be developed. The antibiotic commission of our hospital gave new recommendations for daptomycin use in 2011. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Isolated premature menarche is isolated or recurrent vaginal bleeding in a female in the absence of appropriate secondary sexual characters. Retrospective chart review of patients with premature menarche, followed by a telephone questionnaire. Charts of patients evaluated in the Pediatric Endocrine Clinic for premature vaginal bleeding from 1982-2013 were reviewed. Of 21 patients identified, 17 could be contacted. Five newly diagnosed patients were recruited during the course of the study. The median age at initial presentation was 7 years. Most patients presented with Tanner I sexual development. Some had more advanced breast staging, which regressed later. All had prepubertal baseline and stimulated gonadotropins. Most of the patients reported a single or few episodes of menses. Two reported continuation of irregular bleeding into adulthood. All reported an adult height within the midparental target height. Premature menarche in the absence of other appropriate secondary sexual characteristics is a benign entity. Most patients have a few isolated episodes of menses that stop spontaneously; some may continue to have periods into adulthood. Unlike true puberty, these patients do not demonstrate advanced skeletal maturation, and the adult height is normal. Fertility appears to be normal. © 2015 S. Karger AG, Basel.

    Propensity score-matched, retrospective cohort study. To determine the risk of developing Alzheimer's disease (AD) in patients with spinal cord injury (SCI). The present study used Taiwan's National Health Insurance Research Database. A total of 9257 patients who had ⩾2 ambulatory visits with a diagnosis of SCI in 2001 were included in the SCI group. The non-SCI group consisted of 37,028 propensity score-matched patients without a diagnosis of SCI. The cumulative incidence of AD was estimated for each of the two patient groups using the Kaplan-Meier method. Stratified Cox proportional hazard regression was then employed to assess the influence of SCI on the risk of AD. During the follow-up period, 25 subjects in the SCI group and 57 in the non-SCI group developed AD. The cumulative incidence of AD in the SCI group was higher than in the non-SCI group (P = 0.0168); and the hazard ratio of AD for the SCI group, as compared to the non-SCI group, was 1.71 (95% CI 1.06-2.76, P = 0.0273). This study suggests that patients with SCI have an increased risk of developing AD.

    Full Text Available Abstract Background In August 2002, the antifungal prophylaxis algorithm for neutropenic hematology/oncology (NHO patients at the Medical Center was changed from conventional amphotericin (AMB to an azole (AZ based regimen (fluconazole [FLU] in low-risk and voriconazole [VOR] in high-risk patients. The aim of our study was to compare outcomes associated with the two regimens, including breakthrough fungal infection, adverse drug events, and costs. Methods Adult, non-febrile, NHO patients who received prophylactic AMB from 8/01/01-7/30/02 or AZ from 8/01/02-7/30/03 were retrospectively evaluated. Results A total of 370 patients (AMB: n = 181; AZ: n = 216 associated with 580 hospitalizations (AMB: n = 259; AZ: n = 321 were included. The incidence of probable/definite breakthrough Aspergillus infections was similar among regimens (AMB: 1.9% vs AZ: 0.6%; p=0.19. A greater incidence of mild/moderate (24.7% vs. 5.3%; p $9,000 increase in mean total costs/hospitalization, the mean acquisition cost associated with AZ was only $947/hospitalization more than AMB. Conclusion While an AZ-based regimen is associated with increased cost, the reduced rate of nephrotoxicity and availability of oral dosage forms, suggests that azoles be used preferentially over AMB. However, an increased rate of severe hepatic toxicity may be associated with VOR.

    Full Text Available Introduction : Abdominal pain has been one of the most common reasons patients seek medical care for centuries. Nowadays, together with laboratory diagnostics and imaging, we are able to make an early diagnosis. This leads to the introduction of early adequate treatment. Aim of the research : To analyse the incidence and causes of complicated acute appendicitis in one medical centre in between 2004 and 2016. Material and methods : A retrospective study covered the period from December 23, 2004 to November 07, 2016. It included 2048 cases of children between 0 and 18 years of age undergoing surgery for suspected acute appendicitis.
 Demographic and clinical characteristics as well as length of hospitalisation, antibiotics schemes, and intraoperative diagnosis were reviewed. Complicated acute appendicitis cases were distinguished and compared with the incidence in world literature. Results : The percentage of complicated acute appendicitis ranged from 39% to 60%. Complicated acute appendicitis occurs much more often in children under 5 years of age. Conclusions : The delay and failure in diagnosis of acute appendicitis results in higher incidence of complicated acute appendicitis; consequently, there are higher costs of treatment. Improving the awareness of parents and primary care physicians may allow faster diagnosis and treatment of acute appendicitis. It was noted that the reform of the National Emergency Medical Services in Poland contributed to a reduction in the incidence of complicated appendicitis.

    1992-01-01

    A retrospective study was undertaken in 1990 of 188 patients with the diagnosis of non small cell carcinoma of the lung referred to the Department of Radiation Oncology in 1984. Most patients (178 out of 188) received a course of radiotherapy. This was definitive in 23, palliative in 148 (primary site in 113, metastases in 16, primary plus metastases in 19) and postoperative in 7. This report is a 5 year follow-up of the 171 patients treated by radiation alone, to assess factors that influence survival. Palliative intent of treatment and poorer performance status were related significantly to increasing stage of disease. The effects of palliative treatment were recorded in 79 cases: in 71 there was a reduction in symptoms. The median survival from diagnosis was 8 months. Using univariate and multi-variate analyses, significant and independent prognostic factors for improved survival were good performance status, absence of systemic symptoms, lower tumour stage and curative intent of treatment (higher radiation dose). However the 5-year survival was only 2%. Long-term survival was associated predominantly with early stage disease but not with the type or intent of treatment. Age, sex, histology and apical site did not influence survival. These results are comparable to those found in the literature and emphasize the need to select patients carefully for either palliative or aggressive treatment. 29 refs., 4 tabs., 3 figs

    Community acquired-Clostridium difficile infection (CDI) has increased also in children in the last years. To determine the incidence of community-acquired CDI and to understand whether Clostridium difficile could be considered a symptom-triggering pathogen in infants. A five-year retrospective analysis (January 2007-December 2011) of faecal specimens from 124 children hospitalized in the Niguarda Ca' Granda Hospital for prolonged or muco-haemorrhagic diarrhoea was carried out. Stool samples were evaluated for common infective causes of diarrhoea and for Clostridium difficile toxins. Patients with and without CDI were compared for clinical characteristics and known risk factors for infection. Twenty-two children with CDI were identified in 5 years. An increased incidence of community-acquired CDI was observed, ranging from 0.75 per 1000 hospitalizations in 2007 to 9.8 per 1000 hospitalizations in 2011. Antimicrobial treatment was successful in all 19 children in whom it was administered; 8/22 CDI-positive children were younger than 2 years. No statistically significant differences in clinical presentation were observed between patients with and without CDI, nor in patients with and without risk factors for CDI. Our study shows that Clostridium difficile infection is increasing and suggests a possible pathogenic role in the first 2 years of life. Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.

    Both counselling and group therapy have been recommended for supporting patients with chronic tinnitus. It is unclear which of these treatments is superior. This retrospective study aimed at comparing relief from tinnitus distress following counselling with that following cognitive group therapy. Distress relief was also compared to the distress level of the waiting group patients. Tinnitus distress was assessed through the Tinnitus Questionnaire (TQ, Goebel and Hiller) at three different times: before treatment (in waiting list patients: at initial contact) and at 3 and 6 months after initial assessment. Data from 21 patients per group were included in the analysis. The initial tinnitus distress scores were similar in all groups (about 48 TQ points out of a maximum of 84). After 3 months, both counselling subjects and group therapy participants exhibited a significant distress reduction of 13 TQ points, which remained stable after 6 months. Patients on the waiting list experienced no distress relief over time. Results from our data demonstrate the need for a future prospective study on the comparison of efficacy of counselling vs cognitive group therapy.

    The aim of this study was to investigate the efficacy of nootropics (piracetam, aniracetam, nimodopine and dihydroergicristine) versus acetylcholinesterase inhibitors (AChE-Is) (tacrine and donepezil) in the treatment of Alzheimer's disease. This is a retrospective study of 510 patients with Alzheimer's disease. To determine clinical efficacy of treatment, we used the mean change over time in scores for the following tests: the Mini-Mental State Examination (MMSE); the Cambridge Cognitive Examination for the Elderly; and the Functional Rating Scale for Symptoms of Dementia. In all patients and in patients with severe Alzheimer's disease (baseline MMSE nootropics (-4.38 for AChE-Is group versus 1.48 for nootropics group). For patients with mild dementia (baseline MMSE score between 21 and 26), there was a significantly greater deterioration on the MMSE scale for each time-point in the nootropics group compared with the AChE-Is group. In conclusion, we did not find any strong evidence that a difference in efficacy exists between AChE-Is and nootropics in the treatment of Alzheimer's disease.

    Given that there are currently no clear recommendations regarding therapeutic options for rituximab refractory/relapsed follicular lymphoma patients, this study aimed to describe the real-life management of patients with refractory follicular lymphoma after systemic rituximab-containing regimens (rFL), and rFL patient characteristics. In this retrospective, national, multicentre study, descriptive analyses were mainly performed according to rituximab-containing regimen at rFL diagnosis [rituximab monotherapy (R-MONO), rituximab + chemotherapy (R-COMBO), and ongoing rituximab maintenance (R-MAINTAIN)]. The 459 analysed patients experienced rituximab-refractoriness between October 2013 and September 2015: R-MONO: 58 (13%), R-COMBO: 197 (43%), R-MAINTAIN: 204 (44%). Post-refractoriness strategies were heterogeneous: idelalisib ± rituximab (22%), without anti-lymphoma treatment (21%), rituximab-chemotherapy (21%) and stem cell transplantation (18%). Rituximab was continued in combination in 41% of cases. Chosen strategies varied according to patient age (without anti-lymphoma treatment: 28% of patients if ≥65 years vs. 12% if management and for the design of clinical trials in these patients. © 2017 John Wiley & Sons Ltd.

    2018-02-01

    A multicenter, retrospective, cohort study was conducted in the Netherlands. The aim was to evaluate whether surgical volume of laparoscopic hysterectomies (LHs) performed by proven skilled gynecologists had an impact on the conversion rate from laparoscopy to laparotomy. In 14 hospitals, all LHs performed by 19 proven skilled gynecologists between 2007 and 2010 were included in the analysis. Surgical volume, conversion rate and type of conversion (reactive or strategic) were retrospectively assessed. To estimate the impact of surgical volume on the conversion rate, logistic regressions were performed. These regressions were adjusted for patient's age, Body Mass Index (BMI), ASA classification, previous abdominal surgery and the indication (malignant versus benign) for the LH. During the study period, 19 proven skilled gynecologists performed a total of 1051 LHs. Forty percent of the gynecologists performed over 20 LHs per year (median 17.3, range 5.4-49.5). Conversion to laparotomy occurred in 5.0% of all LHs (53 of 1051); 38 (3.6%) were strategic and 15 (1.4%) were reactive conversions. Performing over 20 LHs per year was significantly associated with a lower overall conversion rate (OR adjusted 0.43, 95% CI 0.24-0.77), a lower strategic conversion rate (OR adjusted 0.32, 95% CI 0.16-0.65), but not with a lower reactive conversion rate (OR adjusted 0.96, 95% CI 0.33-2.79). A higher annual surgical volume of LHs by proven skilled gynecologists is inversely related to the conversion rate to laparotomy, and results in a lower strategic conversion rate.

    The major aims of this study were to identify factors that may predict the diagnostic conversion from major depressive disorder (MDD) to bipolar disorder (BP) and to evaluate the predictive performance of the bipolar spectrum disorder (BPSD) diagnostic criteria. The medical records of 250 patients with a diagnosis of MDD for at least 5 years were retrospectively reviewed for this study. The diagnostic conversion from MDD to BP was observed in 18.4% of 250 MDD patients, and the diagnostic criteria for BPSD predicted this conversion with high sensitivity (0.870) and specificity (0.917). A family history of BP, antidepressant-induced mania/hypomania, brief major depressive episodes, early age of onset, antidepressant wear-off, and antidepressant resistance were also independent predictors of this conversion. This study was conducted using a retrospective design and did not include structured diagnostic interviews. The diagnostic criteria for BPSD were highly predictive of the conversion from MDD to BP, and conversion was associated with several clinical features of BPSD. Thus, the BPSD diagnostic criteria may be useful for the prediction of bipolar diathesis in MDD patients. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Background. Portal cavernoma (PC is the most critical condition with risk or variceal hemorrhage in pediatric patients. We retrospectively investigated the patients with PC focusing on the predictors for recurrent variceal bleeding. Methods. Between July 2003 and June 2013, we retrospectively enrolled all consecutive patients admitted to our department with a diagnosis of PC without abdominal malignancy or liver cirrhosis. The primary endpoint of this observational study was recurrent variceal bleeding. Independent predictors of recurrent variceal bleeding were identified using the logistic regression model. Results. A total of 157 patients were enrolled in the study. During the follow-up period, 24 patients exhibited onset of recurrent variceal bleeding. Acute variceal bleeding was subjected to conservative symptomatic treatment and emergency endoscopic sclerotherapy. Surgical procedure selection was based on the severity of vascular dilation and collateral circulation. Multivariate logistic regression analysis demonstrated that the presence of ascites, collateral circulation, and portal venous pressure were independent prognostic factors of recurrent variceal bleeding for patients with portal cavernoma. Conclusions. The presence of ascites, collateral circulation, and portal venous pressure evaluation are important and could predict the postsurgical recurrent variceal bleeding in patients with portal cavernoma.

    Nursing sensitive outcomes are adverse patient health outcomes that have been shown to be associated with nursing care. Researchers have developed specific algorithms to identify nursing sensitive outcomes using administrative data sources, although contention still surrounds the ability to adjust for pre-existing conditions. Existing nursing sensitive outcome detection methods could be improved by using look-back periods that incorporate relevant health information from patient's previous hospitalisations. Retrospective cohort study at three tertiary metropolitan hospitals in Perth, Western Australia. The objective of this research was to explore the effect of using linked hospitalisation data on estimated incidence rates of eleven adverse nursing sensitive outcomes by retrospectively extending the timeframe during which relevant patient disease information may be identified. The research also explored whether patient demographics and/or the characteristics of their hospitalisations were associated with nursing sensitive outcomes. During the 5 year study period there were 356,948 hospitalisation episodes involving 189,240 patients for a total of 2,493,654 inpatient days at the three tertiary metropolitan hospitals. There was a reduction in estimated rates for all nursing sensitive outcomes when a look-back period was applied to identify relevant health information from earlier hospitalisations within the preceding 2 years. Survival analysis demonstrates that the majority of relevant patient disease information is identified within approximately 2 years of the baseline nursing sensitive outcomes hospitalisation. Compared to patients without, patients with nursing sensitive outcomes were significantly more likely to be older (70 versus 58 years), female, have Charleson comorbidities, be direct transfers from another hospital, have a longer inpatient stay and spend time in intensive care units (p≤0.001). The results of this research suggest that nursing sensitive

    The diagnostic for prostate cancer is changing. To improve the detection of this cancer, urologists expect a lot from the contribution of magnetic resonance imaging (MRI). What is the role of this imaging in prostate cancer detection? This is a retrospective study, from 2011 to 2013, mono-centric and single-operator. Of the 464 needle biopsy of the prostate (BP), we excluded those with PSA>20 ng/mL or digital rectal examination (DRE)>T3. The remaining 430 BP were submitted or not to a 1.5 tesla MRI with pelvic antenna. The primary aim is the overall detection of prostate cancer. Secondary aim was the detection rate during the first series of BP and repeat BP, between the two groups in the MRI group. MRI and MRI without populations are comparable for age (63.3 vs 64.6), PSA (6.10 vs 6.13), DRE>T1c, prostate volume (55.4 cm(3) vs 51.7 cm(3)). There is no significant difference in overall detection between the two groups (P=0.12). There is no significant difference in cancer detection between the first BP (P=0.13) and the repeat BP (P=0.07). There is a significant difference in the early detection of BP MRI group (P=0.03) but not for the BP repeat MRI group (P=0.07). For 108 BP iterative MRI group, there were 67 BP targeted "mentally" with MRI: 18 cancers were detected, making a 25% detection rate. This study helps to highlight the value of MRI in the early rounds of BP but we can ask the value of this imaging during repeat biopsies. Targeted biopsies "mentally" do not have the expected detection sensitivity and seems to require a three-dimensional reconstruction to be more effective. 5. Copyright © 2015 Elsevier Masson SAS.

    As many doctors know little about gas-forming synergistic necrotizing cellulitis, we retrospectively explored it in our study. Totally, 30 patients diagnosed with gas-forming synergistic necrotizing cellulitis between November 2006 and September 2015 were included. They were divided into two groups: open drainage group (19 patients) and aggressive debridement group (11 patients). Retrospectively analyzed data comprised demographic characteristics, APACHE II scores, pathogen culture results, bleeding amount during the operation, white blood cell count, length of hospital stay and recovery. The mortality rate was 26% in the open drainage group and 73% in the aggressive debridement group (p=0.023). There was no statistical difference in the APACHE II score before treatment between the open drainageand aggressive debridement groups (16.6±4.5 vs 18.1±7.5, p=0.511). The APACHE II score was significantly higher after treatment in the aggressive debridement group (14.2±5.8 score vs 20.1±9.1, p=0.038). There were no statistical differences in the white blood count cell before and after treatment (13.49 × 109±5.05×109 cells/L vs 17.46×109±6.94×109 cells/L, p=0.082; 10.37×109±3.54×109 cells/L vs 15.47×109 ±7.51×109 cells/L, p=0.055; respectively). The bleeding amount during the operation was significantly more in the aggressive debridement group (315±112 ml vs 105±45 ml, pgas-forming synergistic necrotizing cellulitis, performing open drainage as early as possible isthe most important procedure after admission.

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

    The incidence of infectious spondylodiscitis has been shown to rise with age; however, they had not been extensively investigated in the very elderly. This retrospective, monocentric study included patients hospitalized in our department of rheumatology for primary infectious spondylodiscitis between 2000 and 2015, and compared over 75-year-olds with younger patients. Of the 152 patients, 51 (33.6%) were≥75 years old, 59 were 61-74, and 42 were≤60. Patients≥75 years old were more often institutionalized (7.8 vs. 0; P=.02), were less often subject to infection risk factors (27.5 vs. 54.5%; P=.02), but did not differ from the others as regards the frequency of diabetes and cancer. Time to diagnosis was shorter for the under 60-year-olds (23 vs. 30 vs. 30 day for each age group, respectively; P<.05). There were no differences among the age groups in terms of spondylodiscitis localization, frequency of neurological symptoms and fever, frequency or intensity of inflammatory syndrome, imaging use, frequency of microorganism identification, blood culture positivity, or use and efficacy of disco-vertebral biopsy. Microorganism distribution was comparable among the groups, except for Gram-negative bacilli, with Escherichia coli more common in over 75-year-olds (7/8 vs. 4/14; P=.02). Duration of antibiotherapy and hospitalization was comparable across the age groups. Five patients died, all over 75 years old (5/51 vs. 0/101; P=.001). Age is a risk factor for primary spondylodiscitis, associated with significant mortality in over 75-year-olds (10%). For these elderly patients, spondylodiscitis does not bear any other distinguishing features. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    Full Text Available The article reports the findings of a retrospective study which looked at Hungarian learners’ attitudes towards Russian people, the Russian language and teachers of Russian. Mixed-methods sequential explanatory design (Ivankova, Creswell, & Stick, 2006 was applied which combines the collection and analysis of quantitative and qualitative data in two consecutive phases. First person accounts turned out to be a useful and relevant resource for exploring individual differences in proficiency in Russian. Differences in attitudes appear to play a role in the developmental process, but to what extent this refers to attrition or non-acquisition is unclear.

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

    Purpose: To present, analyze, and discuss results of a nationwide, multicenter, retrospective study on high-dose-rate brachytherapy (HDR-BT) as monotherapy for low-, intermediate-, and high-risk prostate cancer. Methods and Materials: From 1995 through 2013, 524 patients, 73 (14%) with low-risk, 207 (40%) with intermediate-risk, and 244 (47%) with high-risk prostate cancer, were treated with HDR-BT as monotherapy at 5 institutions in Japan. Dose fractionations were 27 Gy/2 fractions for 69 patients (13%), 45.5 Gy/7 fractions for 168 (32%), 49 Gy/7 fractions for 149 (28%), 54 Gy/9 fractions for 130 (25%), and others for 8 (2%). Of these patients, 156 (30%) did not receive androgen deprivation therapy, and 202 patients (39%) did receive androgen deprivation therapy 3 years. Median follow-up time was 5.9 years (range, 0.4-18.1 years), with a minimum of 2 years for surviving patients. Results: After 5 years, respective actuarial rates of no biochemical evidence of disease, overall survival, cause-specific survival, and metastasis-free survival for all patients were 92%, 97%, 99%, and 94%. For low/intermediate/high-risk patients, the 5-year no biochemical evidence of disease rates were 95%/94%/89%, the 5-year overall survival rates were 98%/98%/94%, the 5-year cause-specific survival rates were 98%/100%/98%, and the 5-year metastasis-free survival rates were 98%/95%/90%, respectively. The cumulative incidence of late grade 2 to 3 genitourinary toxicity at 5 years was 19%, and that of late grade 3 was 1%. The corresponding incidences of gastrointestinal toxicity were 3% and 0% (0.2%). No grade 4 or 5 of either type of toxicity was detected. Conclusions: The findings of this nationwide, multicenter, retrospective study demonstrate that HDR-BT as monotherapy was safe and effective for all patients with low-, intermediate-, and high-risk prostate cancer.

    OBJECTIVE Intramedullary spinal cord tumors comprise 1%-10% of all childhood central nervous system neoplasms, with astrocytomas representing the most common subtype. Due to their rarity and poor prognosis, large population-based studies are needed to assess the epidemiology and survival risk factors associated with these tumors in the hope of improving outcome. The authors undertook this retrospective study to explore factors that may influence survival in pediatric patients with spinal cord astrocytomas. METHODS Utilizing the Surveillance, Epidemiology, and End Results (SEER) database, a prospective cancer registry, the authors retrospectively assessed survival in histologically confirmed, primary spinal cord astrocytomas in patients 21 years of age and younger. Survival was described with Kaplan-Meyer curves, and a multivariate regression analysis was used to assess the association of several variables with survival while controlling for confounding variables. RESULTS This analysis of 348 cases showed that age (hazard ratio [HR] 1.05, 95% CI 1.01-1.09, p = 0.017), nonwhite race (HR 1.74, 95% CI 1.11-2.74, p = 0.014), high-grade tumor status (HR 14.67, 95% CI 6.69-32.14, p < 0.001), distant or invasive extension of the tumor (HR 2.37, 95% CI 1.02-5.49, p = 0.046), and radiation therapy (HR 3.74, 95% CI 2.18-6.41, p < 0.001) were associated with decreased survival. Partial resection (HR 0.37, 95% CI 0.16-0.83, p = 0.017) and gross-total resection (HR 0.39, 95% CI 0.16-0.95, p = 0.039) were associated with improved survival. CONCLUSIONS Younger age appears to be protective, while high-grade tumors have a much worse prognosis. Early diagnosis and access to surgery appears necessary for improving outcomes, while radiation therapy has an unclear role. There is still much to learn about this disease in the hope of curing children with the misfortune of having one of these rare tumors.

    The risk of skin cancer in patients with alopecia areata (AA) is unknown. While the risk of skin cancer in chronic inflammatory alopecias may be elevated, AA shares many characteristics with vitiligo, an autoimmune illness associated with decreased risk of melanoma and non-melanoma skin cancers. In this retrospective cohort study, we determined the risk of developing skin cancer among patients with AA in a validated cohort relative to matched controls at two tertiary care hospitals in Massachusetts. There was a significantly decreased risk of NMSC in AA patients than controls (OR=0.63, 95% CI=0.48-0.81). There was a trend towards a protective effect of AA associated with melanoma (OR=0.65, 95% CI=0.39-1.09). There was no difference in anatomic distribution of skin cancer between patients with AA and controls. Our study demonstrates a decreased risk of nonmelanoma skin cancer and a trend towards reduced risk of melanoma in patients with AA. Copyright © 2016. Published by Elsevier Ltd.

    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.

    Orthopedic and trauma surgery is the specialty for which claims for compensation are most often filed. Little data exists on the subject in France, especially in a teaching hospital. We conducted a retrospective study aimed at (1) identifying the epidemiological characteristics of patients filing claims against the orthopedic surgery and traumatology department of a teaching hospital in France, (2) analyzing the surgical procedures involved, the type of legal proceedings, and the financial consequences. The epidemiological profile of proceedings seeking damages in France is consistent with the data from European and American studies. An observational, retrospective, single-center study of all claims for damages between 2007 and 2016 involving the orthopedic and trauma surgery department of a teaching hospital was carried out. Patients' epidemiological data, the surgical procedure, type of legal proceeding, and financial consequences were analyzed. Of the 51,582 surgical procedures performed, 71 claims (0.0014%) were analyzed (i.e., 1/726 procedures). A significant increase in the number of cases (p=0.040) was found over a 10-year period. Of these, 36/71 (53.7%) were submitted to the French regional conciliation and compensation commission (CRCI), 23/71 (32.8%) were filed with the administrative court, and 12/71 (13.4%) were submitted for an amicable settlement. The most common reason for which patients filed claims was hospital-acquired infections, with 36/71 (50.7%) cases. Twenty-nine complaints (40.8%) resulted in monetary damages being awarded to the patient, with an average award of € 28,301 (€ 2,400-299,508). Damage awards were significantly higher (pClaims against orthopedic surgeons have been increasing significantly over the last 10 years. Although rare, they represent a significant cost to society.

    In the period 2004-2009, national and regional initiatives were developed in Sweden to improve the quality of sickness certificates. Parameters for assessing the quality of sickness certificates in primary health care have been proposed. The aim of this study was to measure the quality of sickness certification in primary health care by means of assessing sickness certificates issued between 2004 and 2009 in Stockholm. This was a retrospective study using data retrieved from sickness certificates contained in the electronic patient records of 21 primary health care centres in Stockholm County covering six consecutive years. A total number of 236 441 certificates were used in the current study. Seven quality parameters were chosen as outcome measures. Descriptive statistics and regression models with time, sex and age group as explanatory variables were used. During the study period, the quality of the sickness certification practice improved as the number of days on first certification decreased and the proportion of duly completely and acceptable certificates increased. Assessment of need for vocational rehabilitation and giving a prognosis for return to work were not significantly improved during the same period. Time was the most influential variable. The quality of sickness certification practice improved for most of the parameters, although additional efforts to improve the quality of sickness certificates are needed. Measures, such as reminders, compulsory certificate fields and structured guidance, could be useful tools to achieve this objective.

    The (CR-LR) difference technique, based on the CR-39 and LR 115 detectors, for the determination of implanted 210 Po in glass after deposition of short-lived radon progeny, was analyzed in details in this paper. The sensitivities of both detectors were calculated using the Monte Carlo method with V functions particularly derived in our previous works for the detectors used in the present experiments. The dependency of the sensitivity ratio on the removed layer of both detectors was determined and verified experimentally. The simulated sensitivity ratios correlate well with the experimental ones. A major finding of the present work is that the sensitivity ratio between the CR-39 and LR 115 detectors depends only weakly on the ratio between the 238 U and 232 Th concentrations in the glass samples. This is crucial for the application of the (CR-LR) difference technique for retrospective radon exposure assessments, since measurements of the 238 U and 232 Th concentrations in the relatively small real-life glass samples will make the retrospective radon exposure assessments impractical

    Full Text Available Abstract Background Hyponatremia is the most common electrolyte disorder in hospitalized patients and is known to be associated with increased mortality. The administration of antegrade single-shot, up to two liters, histidine-tryptophane-ketoglutarate (HTK solution for adequate electromechanical cardiac arrest and myocardial preservation during minimally invasive aortic valve replacement (MIAVR is a standard procedure. We aimed to determine the impact of HTK infusion on electrolyte and acid–base balance. Methods In this retrospective analysis we reviewed data on patient characteristics, type of surgery, arterial blood gas analysis during surgery and intra-/postoperative laboratory results of patients receiving surgery for MIAVR at a large tertiary care university hospital. Results A total of 25 patients were included in the study. All patients were normonatremic at start of surgery. All patients developed hyponatremia after administration of HTK solution with a significant drop of serum sodium of 15 mmol/L (p  Conclusions Acute hyponatremia during cardioplegia with HTK solution is isotonic and should probably not be corrected without presence of hypotonicity as confirmed by measurement of serum osmolality.

    To evaluate the feasibility to perform peripartum hysterectomy (PH) with the introduction of LigaSure™ vessels-sealing device (LVSD) and how it influenced the surgical outcomes. We retrospectively evaluated procedures and outcome of women undergoing PH during the period between January 2001 and October 2013. Perioperative surgical results of patients undergoing PH using LVSD were compared to patients undergoing PH without LVSD. Forty-nine subjects had PH during the study period. Twenty (41%) hysterectomies were performed for placenta accreta, 8 (16%) for placenta previa, 21 (43%) for atony. Twenty-three subjects had PH using LVSD and 26 subjects had hysterectomy without the use of this device. We observe significant differences in estimated blood loss (p = 0.001), massive blood transfusions (>10 units RBC) (p = 0.025), operative time (p = 0.06). No difference in term of hospital stay and complications were observed (p = 0.78 and p = 0.35). One patient for each group had intraoperative complication (p = 0.9). The use of LVSD during PH does not increase operative complications, blood loss, and operative time in comparison to standard procedure.

    We present a retrospective study of 25 patients with spontaneous pneumothorax (three recurrent) comprising 16 Saudis (nine males and seven females) and eight non-Saudi's (eight males and one female), seen at the Asir Central Hospital, Abha, over a period of 45 months. Almost one-third of patients (9/25) had no underlying cause discernible by our investigational facilities (chest x-ray, ultrasonography, computed tomographic scan and flexible bronchofiberscopy). Underlying pneumonia (three patients), pulmonary tuberculosis (two patients), lung abscess (one patient) and congenital bullae (one patient) constituted the etiology in another third of the spontaneous pneumothorax patients. Other underlying pulmonary diseases, precipitating spontaneous pneumothorax in the group included pulmonary fibrosis, metastatic mesothelioma and immunosuppression in a medulloblastoma patient undergoing chemotherapy with the development of chickenpox. Closed thoracostomy tube drainage was the only method of treatment in 20 out of 25 patients, with three failures of closed thoracostomy tube drainage needing thoractomy and resection of blebs/bullae. The only complication was empyema in two of the patients. Two patients were successfully treated conservatively with observation alone. (author)

    This is a descriptive analysis, of victims of Turkey's October 23, 2011 and November 21, 2011 Van earthquakes. The goal of this study is investigated the injury profile of the both earthquakes in relation to musculoskeletal trauma. We retrospectively reviewed medical records of 3,965 patients admitted to in seven hospitals. A large share of these injuries were soft tissue injuries, followed by fractures, crush injuries, crush syndromes, nerve injuries, vascular injuries, compartment syndrome and joint dislocations. A total of 73 crush injuries were diagnosed and 31 of them were developed compartment syndrome. The patients with closed undisplaced fractures were treated with casting braces. For closed unstable fractures with good skin and soft-tissue conditions, open reduction and internal fixation was performed. All patients with open fracture had an external fixator applied after adequate debridement. Thirty one of 40 patients with compartment syndrome were treated by fasciotomy. For twelve of them, amputation was necessary. The most common procedure performed was debridement, followed by open reduction and internal fixation and closed reduction-casting, respectively. The results of this study may provide the basis for future development of strategy to optimise attempts at rescue and plan treatment of survivors with musculoskeletal injuries after earthquakes.

    The aim of this retrospective study was to compare the esthetic, periodontal, and functional outcomes of orthodontic space closure versus implant substitution in patients with missing maxillary incisors 5 years after completion of treatment. The study group consisted of ten patients treated with orthodontic space closure (six males, four females, mean age 19 ± 2.1 years at the completion of treatment) and ten patients treated with implant insertion (five males, five females, mean age 20 ± 1.4 years at the time of implant insertion). Tooth mobility, plaque index, probing depth, infraocclusion, open gingival embrasure (black triangle), and temporomandibular joint function were recorded at the 5.6 years follow-up. Self-perceived dental esthetic appearance was also evaluated through a visual analog scale (VAS) questionnaire. T-test was used to evaluate the data. All patients were equally satisfied with the appearance of their teeth 5.6 ± 0.4 years after the completion of treatment. No statistically significant differences were found in relation to the VAS scores of the subjects (P Orthodontic space closure and implant of missing maxillary incisors produced similar, well-accepted esthetic results. None of the treatments impaired temporomandibular joint function. Nevertheless, infraocclusion was evident in implant patients. Space closure patients also showed better periodontal health in comparison with implant patients.

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

    Changes in population birth outcomes, including increases in low birthweight or preterm births, have been documented after natural and manmade disasters. However, information is limited following the 2011 Fukushima Daiichi Nuclear Power Plant Disaster. In this study, we assessed whether there were long-term changes in birth outcomes post-disaster, compared to pre-disaster data, and whether residential area and food purchasing patterns, as proxy measurements of evacuation and radiation-related anxiety, were associated with post-disaster birth outcomes. Maternal and perinatal data were retrospectively collected for all live singleton births at a public hospital, located 23 km from the power plant, from 2008 to 2015. Proportions of low birthweight (effects on maternal and perinatal health.

    This retrospective study summarizes 11 cases of end-stage renal disease (ESRD) in captive polar bears (Ursus maritimus) from eight zoologic institutions across the United States and Canada. Ten bears were female, one was male, and the mean age at the time of death was 24 yr old. The most common clinical signs were lethargy, inappetence, and polyuria-polydipsia. Biochemical findings included azotemia, anemia, hyperphosphatemia, and isosthenuria. Histologic examination commonly showed glomerulonephropathies and interstitial fibrosis. Based on submissions to a private diagnostic institution over a 16-yr period, ESRD was the most commonly diagnosed cause of death or euthanasia in captive polar bears in the United States, with an estimated prevalence of over 20%. Further research is needed to discern the etiology of this apparently common disease of captive polar bears.

Br J Clin Pharmacol 2017; 83: 1163-5. https://doi.org/10.1111/bcp.13279 AIMS: Treatment of paracetamol (acetaminophen) overdose with acetylcysteine is standardized, with dose determined only by patient weight. The validity of this approach for massive overdoses has been questioned. We systematically compared outcomes in massive and non-massive overdoses, to guide whether alternative treatment strategies should be considered, and whether the ratio between measured timed paracetamol concentrations (APAP pl ) and treatment nomogram thresholds at those time points (APAP t ) provides a useful assessment tool. This is a retrospective observational study of all patients (n = 545) between 2005 and 2013 admitted to a tertiary care toxicology service with acute non-staggered paracetamol overdose. Massive overdoses were defined as extrapolated 4-h plasma paracetamol concentrations >250 mg l -1 , or reported ingestions ≥30 g. Outcomes (liver injury, coagulopathy and kidney injury) were assessed in relation to reported dose and APAP pl :APAP t ratio (based on a treatment line through 100 mg l -1 at 4 h), and time to acetylcysteine. Ingestions of ≥30 g paracetamol correlated with higher peak serum aminotransferase (r = 0.212, P paracetamol overdose are at higher risk of organ injury, even when acetylcysteine is administered early. Enhanced therapeutic strategies should be considered in those who have an APAP pl :APAP t  ≥ 3.

    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

    Many previous reports have focused on bile leakage after liver resection. Despite the improvements in surgical techniques and perioperative care the incidence of this complication rather keeps increasing. A number of predictive factors have been analyzed. There is still no consensus regarding their influence on the formation of bile leakage. The objective of our analysis was to evaluate the incidence of bile leakage, its impact on mortality and duration of hospitalization at our department. At the same time, we conducted an analysis of known predictive factors. The authors present a retrospective review of the set of 146 patients who underwent liver resection at the Department of Surgery of the 2nd Faculty of Medicine of the Charles University and Central Military Hospital Prague, performed between 20102013. We used the current ISGLS (International Study Group of Liver Surgery) classification to evaluate the bile leakage. The severity of this complication was determined according to the Clavien-Dindo classification system. Statistical significance of the predictive factors was determined using Fishers exact test and Students t-test. The incidence of bile leakage was 21%. According to ISGLS classification the A, B, and C rates were 6.5%, 61.2%, and 32.3%, respectively. The severity of bile leakage according to the Clavien-Dindo classification system - I-II, IIIa, IIIb, IV and V rates were 19.3%, 42%, 9.7%, 9.7%, and 19.3%, respectively. We determined the following predictive factors as statistically significant: surgery for malignancy (pBile leakage significantly prolonged hospitalization time (pbile leakage the perioperative mortality was 23 times higher (pBile leakage is one of the most serious complications of liver surgery. Most of the risk factors are not easily controllable and there is no clear consensus on their influence. Intraoperative leak tests could probably reduce the incidence of bile leakage. In the future, further studies will be required to improve

    Urban development trajectories are changing towards compact, energy-efficient cities and renewable energy sources, and this will strongly affect ecosystem services (ES) that cities are dependent on but tend to disregard. Such ES can be provisioning, regulating and cultural ES, around which competition over land resources will increase with energy system shifts. Much of this can be foreseen to take place within urbanising regions that are simultaneously the living environment of a major part of the human population today. In order to inform critical urban policy decisions, tools for integrated assessment of urban energy and transport options and ecosystem services need to be developed. For this purpose, a case study of the Stockholm region was conducted, analysing three scenarios for the future urbanisation of the region, integrating a transport energy perspective and an ES perspective. The results showed that a dense but polycentric development pattern gives more opportunities for sustainable urban development, while the dense monocentric scenario has apparent drawbacks from an ES perspective. The methodology is compatible with a model integration platform for urban policy support and will thus enable integrated policy assessment of complex urban systems, with the goal of increasing their sustainability. - Highlights: • A diffuse urban pattern leads to low access to jobs and high energy consumption. • A dense monocentric urban pattern implies high energy efficiency and low access to ES. • A dense polycentric urban pattern allows for a combination of urban functions. • ES needs to be integrated into sustainability assessments of urban policy options.

    Full Text Available Abstract Background Studies indicate that there is high early mortality among patients starting antiretroviral treatment in sub-Saharan Africa. However, there is paucity of evidence on long term survival of patients on anti-retroviral treatment in the region. The objective of this study is to examine mortality and its predictors among a cohort of HIV infected patients on anti-retroviral treatment retrospectively followed for five years. Methods A retrospective cohort study was conducted among HIV infected patients on ART in eastern Ethiopia. Cox regression and Kaplan-Meier analyses were performed to investigate factors that influence time to death and survival over time. Result A total of 1540 study participants were included in the study. From the registered patients in the cohort, the outcome of patients as active, deceased, lost to follow up and transfer out was 1005 (67.2%, 86 (5.9%, 210 (14.0% and 192 (12.8% respectively. The overall mortality rate provides an incidence density of 2.03 deaths per 100 person years (95% CI 1.64 - 2.50. Out of a total of 86 deaths over 60 month period; 63 (73.3% died during the first 12 months, 10 (11.6% during the second year, and 10 (11.6% in the third year of follow up. In multivariate analysis, the independent predictors for mortality were loss of more 10% weight loss, bedridden functional status at baseline, ≤ 200 CD4 cell count/ml, and advanced WHO stage patients. Conclusion A lower level of mortality was detected among the cohort of patients on antiretroviral treatment in eastern Ethiopia. Previous history of weight loss, bedridden functional status at baseline, low CD4 cell count and advanced WHO status patients had a higher risk of death. Early initiation of ART, provision of nutritional support and strengthening of the food by prescription initiative, and counseling of patients for early presentation to treatment is recommended.

    Full Text Available Background. Fasting during the lunar month of Ramadan is mandatory to all healthy adult Muslims. Renal transplant recipients are often worried about the impact of fluid and electrolyte deprivation during fasting on the function of their allograft. We aimed to examine the effect of fasting Ramadan on the graft function in renal transplant recipients. Methods. This retrospective cohort study included patients who underwent kidney transplantation in our tertiary referral center. Baseline pre-Ramadan estimated glomerular filtration rate (eGFR, mean arterial pressure (MAP, and urinary protein excretion were compared to those during and after Ramadan within and between the fasting and non-fasting groups. Results. The study population included 280 kidney transplant recipients who chose to fast during the Ramadan month (June-July 2014 and 285 recipients who did not fast. In the fasting group, baseline eGFR did not change from that during or post-Ramadan (72.6±23.7 versus 72.3±24.5 mL/min/1.73 m2, P=0.53; and 72.6±23.7 versus 72±23.2 mL/min/1.73 m2, P=0.14, respectively. Compared to baseline, there were no significant differences between the fasting and the non-fasting groups in terms of mean percent changes in eGFR, MAP, and urinary protein excretion. Conclusion. Fasting during the month of Ramadan did not have significant adverse effects on renal allograft function.

    Full Text Available The use of venous catheters is a widespread practice, especially in oncological and oncohematological units. The objective of this study was to evaluate the complications associated with peripherally inserted central catheters (PICCs in a cohort of patients.In this retrospective cohort study, we included all patient carrying PICCs (n = 603 inserted at our institute between October 2010 and December 2013. The main variables collected were medical diagnosis, catheter care, location, duration of catheterization, reasons for catheter removal, complications, and nursing care. Complications were classified as infection, thrombosis, phlebitis, migration, edema, and/or ecchymosis.All patients were treated according to the same "nursing care" protocol. The incidence rate of complications was two cases per 1000 days of catheter duration. The most relevant complications were infection and thrombosis, both with an incidence of 0.17 cases per 1000 days of the total catheterization period. The total average duration of catheterization was 170 days [SD 6.06]. Additionally to "end of treatment" (48.42% and "exitus", (22.53% the most frequent cause of removal was migration (displacement towards the exterior of the catheter (5.80%.PICCs are safe devices that allow the administration of long-term treatment and preserve the integrity of the venous system of the patient. Proper care of the catheter is very important to improve the quality life of patients with oncologic and hematologic conditions. Therefore, correct training of professionals and patients as well as following the latest scientific recommendations are particularly relevant.

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

    Retrospective studies on oral cancer patient profiles related to risk habits could provide etiologic clues for prevention in specific geographic areas. To study risk habit characteristics of oral cancer patients. A cross sectional retrospective case record study of oral cancer patients who reported during 1991-2000 to Karnataka Cancer Therapy and Research Institute, Hubli, India was conducted. Data on socio-demography, histopathology, site of cancer and risk habit profiles of the patients were recorded in a predesigned Performa by one calibrated examiner with internal validity checks. The 1,472 oral cancer patients constituted 11% of total cancer patients. Mean age of the patients was 55 years, ranging from 12-88, with a male: female ratio of 2:1. 1,110 (75%) oral cancer patients had risk habits, 55% were habituated for >10 years and 25% were habit free. 751(51%) patients had individual and 359(24%) had combined risk habits. Majority 59% were chewers of betel quid alone (17%)/betel quid with tobacco (42%); smokers were (31%) and alcohol users were (14%) of patients. Chewers of gutkha, khaini were more in 40 years. Risk habituates were highest (87%) in patients with cancer of buccal mucosa, commonly affected site attributed to chewing habit in (51%) of patients. The prevalence of oral cancer was higher among elderly males predominantly with risk habits of betel quid/tobacco chewing and smoking for more than 10 years.

    increasingly, reflection is highlighted as integral to core practice competencies but empirical research into the relationship between reflection and performance in the clinical workplace is scarce. this study investigated the relationship between reflection ability and clinical performance. we designed a cross-sectional and a retrospective-longitudinal cohort study. Data from first, second and third year midwifery students were collected to study the variables 'clinical performance' and 'reflection ability'. Data were analysed with SPSS for Windows, Release 20.0. Descriptive statistics, Pearson׳s Product Moment Correlation Coefficients (r) and r² values were computed to investigate associations between the research variables. the results showed a moderate observed correlation between reflection ability and clinical performance scores. When adopting a cross-sectional perspective, all correlation values were significant (p0.6). The results based on the retrospective-longitudinal data set explained a moderate proportion of the variance after correction for attenuation. Finally, the results indicate that 'reflection ability' scores of earlier years are significant related with 'clinical performance' scores of subsequent years. These results suggest that (1) reflection ability is linked to clinical performance; (2) that written reflections are an important, but not the sole way to assess professional competence and that (3) reflection is a contributor to clinical performance improvement. the data showed a moderate but significant relationship between 'reflection ability' and 'clinical performance' scores in clinical practice of midwifery students. Reflection therefore seems an important component of professional competence. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2017-08-01

    Full Text Available Background Liver transplantation (LT is a complicated procedure with a high incidence of postoperative acute kidney injury (AKI. Previous studies indicate that even transient or mild post-LT AKI can result in critical conditions, including prolonged stays in hospitals and intensive care units and increased morbidity and mortality. The aim of this study was to investigate the association between body mass index (BMI and occurrence of AKI in LT recipients. Methods Medical data from 203 patients who received LT surgery from January 2010 to August 2016 in a single university hospital setting were retrospectively collected and analyzed. Patients were classified as either underweight (BMI <20 kg/m2 or normal weight (20 ≤ BMI < 30 kg/m2. Demographic data, anesthetic methods, complications, and perioperative laboratory test values of each patient were assessed. Propensity analyses and logistic regression were performed to evaluate the association between BMI and post-LT AKI. Results There was no significant difference in occurrence of post-LT AKI between underweight and normal weight patients. The underweight patient group had significantly longer hospital stay compared with the normal weight patient group (P = 0.023. Conclusions BMI classification was neither a positive nor negative predictor of postoperative AKI occurrence. However, patients with lower BMI had significantly longer hospital stay compared with their counterparts. Although our study was limited by its retrospective design, our observations suggest that lower BMI might play a role in post-LT AKI.

    Objective To explore potential risk factors and early manifestations of avoidant personality disorder (AVPD) by examining retrospective reports of social functioning and adverse childhood experiences. Method Early social functioning and pathological childhood experiences were assessed using the Childhood Experiences Questionnaire-Revised. The responses of 146 adults diagnosed with primary AVPD were compared with a group of 371 patients with other personality disorders as a primary diagnosis and a group of 83 patients with current major depression disorder and no personality disorders, using χ2 analyses. Diagnoses were based on semistructured interviews by trained reliable clinicians. Results Adults with AVPD reported poorer child and adolescent athletic performance, less involvement in hobbies during adolescence, and less adolescent popularity than the depressed comparison group and the other personality disorder group. Reported rates of physical and emotional abuse were higher than the depressed group, but this result was influenced by comorbid diagnoses. Conclusions These results suggest that early manifestations of AVPD are present in childhood but that various forms of abuse are not specific to the disorder. PMID:12960713

    Chernobyl accident, which occurred on April 26, 1986 at NPP located less than 150 km north of Kiev, is the largest nuclear accident ever. Unprecedented scale of the accident was determined not only by the amount of released activity, but also by a number of population and workers involved and, therefore, exposed to enhanced doses of ionizing radiation. Population of the 30-km exclusion zone numbering about 116,000 persons of all ages and both genders was evacuated within days and weeks after the accident, emergency workers called ''liquidators of the accident'' (males age 20-50) were involved into clean-up and recovery for 5 years and their number is estimated as 600,000, about 300,000 are Ukrainian citizens. Due to unexpected and excessively large scale accident, none of residents had personal dosimeters, personal dosimetry of liquidators was not total, dosimetry techniques and practices were far from the optimum. As a result, an acute need for retrospective dose assessment was dictated by radiation protection and research considerations. This need was responded by implementation of wide scale dose reconstruction efforts, which covered main exposed cohorts and encompassed broad variety of newly developed methods: analytical (time-and-motion), modeling, biological and physical (EPR spectroscopy of teeth, TL of quartz). The presentation summarizes vast experience accumulated by RCRM in the field of retrospective dosimetry of large cohorts of exposed population and professionals. These dose reconstruction projects were implemented, in particular, in the framework of epidemiological studies, designed to follow-up medical consequences of Chernobyl accident and study health effects of ionizing radiation, in particular, Ukrainian-American studies of cataracts and leukemia among liquidators. Over 25 years passed after Chernobyl accident a broad variety of retrospective dosimetry problems was addressed by the team of Research Center for Radiation Medicine AMS Ukraine. In

    High levels of scatter radiation in catheterization laboratories may lead to posterior subcapsular opacities in the lens of the staff. The international Retrospective Evaluation of Lens Injuries and Dose (RELID) was performed in Argentina for the first time in 2010 in the context of the congress of the Latin American Society of Interventional Cardiology (SOLACI) and recently, in 2014, was carried out for the second time (SOLACI-CACI 2014). The 2014 study included 115 participants: interventional cardiologists, technicians and nurses. Posterior subcapsular lens changes typical of ionizing radiation exposure were found in 91.5% of interventional cardiologists, in 77% of technicians and in 100% of nurses, according to the Merriam-Focht scale. This RELID study (Argentina 2014) has particular importance since it allowed the follow-up of 10 professionals evaluated in 2010. The results obtained in the study population highlight the importance of the availability and proper use of the elements of radiation protection, as well as staff training. (authors)

    Full Text Available The objective of this randomised, controlled, parallel-group monocentric clinical trial was to assess the efficacy (at low and high dose and the safety (at high dose of a recombinant canarypox virus (ALVAC® expressing feline interleukin 2 (IL-2. ALVAC IL-2 was administered to cats as an adjunct treatment of feline fibrosarcoma in complement to surgery and brachytherapy (reference treatment. Seventy-one cats with a first occurrence of feline fibrosarcoma were referred to the Veterinary Oncology Centre for post-surgical radiotherapy. They were randomly assigned to three treatment groups: reference treatment group (23 cats, ALVAC IL-2 low dose group (25 cats and ALVAC IL-2 high dose group (23 cats. Two dosages of ALVAC IL-2 were used to assess both safety (high dose and efficacy (high and low doses. The treatment consisted of six consecutive doses of ALVAC IL-2 administered subcutaneously at the tumour site on Day 0 (one day before brachytherapy treatment, Day 7, Day 14, Day 21, Day 35 and Day 49.

    Full Text Available This study was conducted as a retrospective analysis of Northern Foods Plc., once a major player in FTSE 350 Food Sector, to evaluate its financial situation over a five year period. The ex post factor research design was used for this study. Annual reports and databases on Northern Foods Plc., and Associated British Foods Plc., were used to perform a series of ratio analyses. The results revealed that Northern Foods Plc.’s performance has been declining as evidenced in the profitability ratios calculated. Also, financial strength was weak and working capital has not been effectively managed, hence affecting its cash and profit generation potentials. The company was limited in its ability to grow and expand as it needed to regularly fund its pension deficit, and finance its high levels of debt. The study concludes that Northern Foods was not in a very strong financial position, yet it was not making the required investments to improve, hence its takeover though this paper will not rule out non-financial issues. Furthermore, the study prescribed five generic points to improve the financial health of any organisation.

    Postpartum haemorrhage (PPH) represents a leading cause of maternal morbidity and mortality. Giving oxytocin after birth reduces the risk for PPH. It has never been tested whether different methods of oxytocin administration affect the maternal outcome. This study aims to compare the infusion versus the bolus application of oxytocin after singleton vaginal delivery. This retrospective monocentre study compares the incidence of clinically relevant postpartum complications in women receiving 5 IE of oxytocin as a bolus or as a 100 ml-infusion over 5 min, given immediately after birth. Included were women delivering singletons vaginally at term. We used propensity score weighting to compare outcomes between women receiving bolus and infusion and to minimize the selection bias in this retrospective cohort. 1765 patients were included. Patient characteristics were balanced. We found no significant differences for the combined overall postpartum adverse outcome (the incidence of PPH, manual removal of the placenta and/or curettage). For the single outcomes, we observed a significantly higher frequency of manual removal of the placenta (Odds ratio 1.47, 95 % CI 1.02-2.13) and a slightly higher but clinically not relevant estimated blood loss (Relative effect 1.05, 95 % CI 1.01-1.10) in the infusion group. The data show a tendency towards more complications in the infusion group. It is related to a more frequent need for manual removal of the placenta.

    The first results of an in-depth evaluation of the practical potential of common household Israeli salt as a retrospective dosemeter in the event of a nuclear accident or terror attack are presented. Ten brands of salt were investigated with emphasis on four of the best-selling brands that constitute 76 % of the total consumer market. Eight of the ten brands show similar glow curves with two main glow peaks at maximum temperatures of ∼176 deg. C and ∼225 deg. C measured at a heating rate of 1 deg. C s -1 . Chemical analysis of three major brands indicates substantial impurity levels of 200-500 ppm of Ca, K, Mg and S and significant differences of additional ppm trace impurities, which lead to an ∼50 % difference in the TL response of the three major brands. Fading in the dark is in significant but under room light is of the order of 35 % per day. The dose response is linear/supralinear with the threshold of supralinearity at ∼0.01 Gy reaching maximum value of ∼4 at 0.5-1 Gy for two of the major brands. The precision of repeated measurements is ∼10 % (1 SD), but the accuracy of dose assessment under field conditions requires further study. (authors)

    our objective was to determine the incidence of toxicity among veterans initiating isoniazid therapy for latent tuberculosis infection (LTBI) and determine whether advancing age was a risk factor for toxicity. we performed a retrospective cohort study among all adults initiating isoniazid treatment for LTBI at a Veterans Medical Center from 1999 to 2005. We collected data on patient demographics, co-morbidities, site of initiation, and treatment outcome. 219 patients initiated isoniazid therapy for LTBI during the period of observation, and the completion of therapy was confirmed in 100 patients (46%). Among 18/219 patients (8%) that discontinued therapy due to a documented suspected toxicity, the median time to onset was 3 months (IQR 1-5 months). In an adjusted Cox regression model, there was no association between discontinuation due to suspected toxicity and advancing age (HR 1.03, 95% CI 0.99, 1.07). In contrast, hepatitis C infection was a significant predictor of cessation due to toxicity in the adjusted analysis (HR 3.03, 95% CI 1.08, 8.52). cessation of isoniazid therapy due to suspected toxicity was infrequently observed among a veteran population and was not associated with advancing age. Alternative LTBI treatment approaches should be further examined in the veteran population.

    Retrospective study based on data extracted from medical records of dogs diagnosed with perineal hernia between 2009 and 2014; medical records of bitches were selected for further analysis to determine the prevalence of perineal hernias in bitches and to investigate potential comorbidities. Perineal hernia was diagnosed in 182 dogs (174 males and 8 females; 96% and 4%, respectively). Surgical correction was performed in 6 bitches. Surgical procedures corresponded to internal obturator muscle transposition with or without polypropylene mesh reinforcement (n = 5) and semitendinosus muscle transposition flap (n = 1). Major comorbidities associated with perineal hernias in adult bitches were trauma (n = 3; 7.3 ± 1.5 years; 7.1 ± 8.5kg) and persistent cough secondary to conditions such as bronchitis, tracheal collapse, and cardiopathy in aged, small-sized patients (n = 3; 13.6 ± 2.0 years; 2.3 ± 0.1kg). Perineal hernias are uncommon in bitches and tend to be associated with comorbidities in these patients. Aged female dogs suffering from uncontrolled chronic cough secondary to cardiopathy or bronchitis are at risk of developing perineal hernia. Previous trauma to the pelvis is another potential risk factor for perineal hernia development in female dogs. Copyright © 2016. Published by Elsevier Inc.

    To evaluate the effectiveness of simulation team training for the management of shoulder dystocia. Primary outcome measures were the number of reported cases of shoulder dystocia, as well as fetal injury that occurred from it. Secondary outcome is documentation of manoeuvres used to alleviate shoulder dystocia. Retrospective cohort study in a teaching hospital in the Netherlands, in a 38 month period before and after implementation of team training. We compared 3492 term vaginal cephalic deliveries with 3496 deliveries before and after team training. Incidence of shoulder dystocia increased from 51 to 90 cases (RR 1.8 (95% CI: 1.3-2.5)). Fetal injury occurred in 16 and eight cases, respectively (RR 0.50 (95% CI: 0.21-1.2)). Before team training started, the all-fours manoeuvre was never used, while after team training it was used in 41 of 90 cases (45%). Proper documentation of all manoeuvres used to alleviate shoulder dystocia significantly increased after team training (RR 1.6 (95% CI: 1.05-2.5)). Simulation team training increased the frequency of shoulder dystocia, facilitated implementation of the all-fours technique, improved documentation of delivery notes and may have a beneficial effect on the number of children injured due to shoulder dystocia.

    Background Floating knee injuries are usually associated with other significant injuries. Do these injuries have implications on the management of the floating knee and the final outcome of patients? Our study aims to assess the implications of associated injuries in the management and final outcome of floating knee. Methods 29 patients with floating knees were assessed in our institution. A retrospective analysis of medical records and radiographs were done and all associated injuries were identified. The impact of associated injuries on delay in initial surgical management, delay in rehabilitation & final outcome of the floating knee were assessed. Results 38 associated injuries were noted. 7 were associated with ipsilateral knee injuries. Lower limb injuries were most commonly associated with the floating knee. Patients with some associated injuries had a delay in surgical management and others a delay in post-operative rehabilitation. Knee ligament and vascular injuries were associated with poor outcome. Conclusion The associated injuries were quite frequent with the floating knee. Some of the associated injuries caused a delay in surgical management and post-operative rehabilitation. In assessment of the final outcome, patients with associated knee and vascular injuries had a poor prognosis. Majority of the patients with associated injuries had a good or excellent outcome.

    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.

    Full Text Available This retrospective study was aimed to identify risk factors of intravenous (IV infiltration for hospitalized children. The participants were 1,174 children admitted to a general hospital, who received peripheral intravenous injection therapy at least once, and had complete records. Data were analyzed with frequency and percentage or mean and standard deviation were calculated, and odds ratio (OR from univariate and multiple logistic regressions. The number and % of infiltrations were 92 and 7.8%, respectively. IV infiltration risk factors were lower limb (OR = 1.72, phenytoin (OR = 11.03, 10% dextrose (OR = 6.55, steroids (OR = 6.21, vancomycin (OR = 4.10, high-concentration electrolytes (OR = 3.49, and ampicillin/sulbactam combination (OR = 3.37. Nurses working at children's hospitals should consider the risk of IV infiltration for children receiving IV infusion therapy and make a preventive effort to identify IV infiltration in high-risk children at an early stage.

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

    2015-01-01

    Objectives The facial bones are the most noticeable area in the human body, and facial injuries can cause significant functional, aesthetic, and psychological complications. Continuous study of the patterns of facial bone fractures and changes in trends is helpful in the prevention and treatment of maxillofacial fractures. The purpose of the current clinico-statistical study is to investigate the pattern of facial fractures over a 4-year period. Materials and Methods A retrospective analysis of 1,824 fracture sites was carried out in 1,284 patients admitted to SMG-SNU Boramae Medical Center for facial bone fracture from January 2010 to December 2013. We evaluated the distributions of age/gender/season, fracture site, cause of injury, duration from injury to treatment, hospitalization period, and postoperative complications. Results The ratio of men to women was 3.2:1. Most fractures occurred in individuals aged between teens to 40s and were most prevalent at the middle and end of the month. Fractures occurred in the nasal bone (65.0%), orbital wall (29.2%), maxillary wall (15.3%), zygomatic arch (13.2%), zygomaticomaxillary complex (9.8%), mandibular symphysis (6.5%), mandibular angle (5.9%), mandibular condyle (4.9%), and mandibular body (1.9%). The most common etiologies were fall (32.5%) and assault (26.0%). The average duration of injury to treatment was 6 days, and the average hospitalization period was 5 days. Eighteen postoperative complications were observed in 17 patients, mainly infection and malocclusion in the mandible. Conclusion This study reflects the tendency for trauma in the Seoul metropolitan region because it analyzes all facial fracture patients who visited our hospital regardless of the specific department. Distinctively, in this study, midfacial fractures had a much higher incidence than mandible fractures. PMID:26734557

Ultimately, these datas have been compared with those in the reputable books and new medical papers; And the results are present at the end of the discussion. Undoubtedly, this study is not free of the limitations of retrospective studies. Our patients-contrary to the textbooks are predominantly males; And also their most common chief complaints are neurological manifestations, and headache (82% is the most common one. There is only a little difference in the prevalence of some of the endocrinologic and ophthalmic manifestations between our datas and what in the texts, while, in some others, we can see a great diversity between the 2. For instance, decreased libido in men and amenorrhea in women, among our patients are prominently less than what we study in the books; And blood pressure disturbances, sensory and motor symptoms and urinary incontinence have not been seen in our patients. In most cases, CT scan leads to diagnosis and its diagnostic accuracy in 2 times higher than that of the simple radiography and it can show the sella enlargement obviously. In a majority of cases (More than 95%, excision a part of the tumor (From just limited to the biopsy area to 90% of tumor mass was the only therapeutic measure. In only a few patients, tumor excision was followed by radiotherapy, that showed the better results. The most common delayed complication was the recurrence of the disease.

    Although reassuring data on suicide risk in UK veterans of the 1982 Falklands conflict and 1991 Gulf conflict have been published, there have been few studies on long-term overall suicide risk in UK veterans. To examine the risk of suicide in a broad population-based cohort of veterans in Scotland, irrespect ive of length of service or exposure to conflict, in comparison with people having no record of military service. A retrospective 30-year cohort study of 56205 veterans born 1945-85 and 172741 matched non-veterans, using Cox proportional hazard models to compare the risk of suicide and fatal self-harm overall, by sex, birth cohort, length of service and year of recruitment. There were 267 (0.48%) suicides in the veterans compared with 918 (0.53%) in non-veterans. The difference was not statistically significant overall [adjusted hazard ratio (HR) 0.99; 95% confidence interval (CI) 0.86-1.13]. The incidence was lower in younger veterans and higher in veterans aged over 40. Early service leavers were at non-significantly increased risk (adjusted HR 1.13; 95% CI 0.91-1.40) but only in the older age groups. Women veterans had a significantly higher risk of suicide than non-veteran women (adjusted HR 2.44; 95% CI 1.32-4.51, P suicide did not differ significantly between veterans and non-veterans, for either sex. The Scottish Veterans Health Study adds to the emerging body of evidence that there is no overall difference in long-term risk of suicide between veterans and non-veterans in the UK. However, female veterans merit further study. © The Author 2017. Published by Oxford University Press on behalf of the Society of Occupational Medicine. All rights reserved.

    Prices for some generic drugs have increased in recent years, adversely affecting patients who rely on them. To determine the association between market competition levels and the change in generic drug prices in the United States. Retrospective cohort study. Prescription claims from commercial health plans between 2008 and 2013. The 5.5 years of data were divided into 11 study periods of 6 months each. The Herfindahl-Hirschman Index (HHI)-calculated by summing the squares of individual manufacturers' market shares, with higher values indicating a less competitive market-and average drug prices were estimated for the generic drugs in each period. The HHI value estimated in the baseline period (first half of 2008) was modeled as a fixed covariate. Models estimated price changes over time by level of competition, adjusting for drug shortages, market size, and dosage forms. From 1.08 billion prescription claims, a cohort of 1120 generic drugs was identified. After adjustment, drugs with quadropoly (HHI value of 2500, indicating relatively high levels of competition), duopoly (HHI value of 5000), near-monopoly (HHI value of 8000), and monopoly (HHI value of 10 000) levels of baseline competition were associated with price changes of -31.7% (95% CI, -34.4% to -28.9%), -11.8% (CI, -18.6% to -4.4%), 20.1% (CI, 5.5% to 36.6%), and 47.4% (CI, 25.4% to 73.2%), respectively, over the study period. Study findings may not be generalizable to drugs that became generic after 2008. Market competition levels were associated with a change in generic drug prices. Such measurements may be helpful in identifying older prescription drugs at higher risk for price change in the future. None.

    Full Text Available Background: Port-site infection (PSI is a prevailing, chronic, nagging, treatment refractory complication of laparoscopic surgery (LS. It neutralizes the advantages of minimally invasive surgery and increases morbidity, treatment cost of patient, leading to loss of confidence on operating surgeon. PSIs are preventable with appropriate preoperative, intraoperative, and postoperative measures. Atypical mycobacterium is most commonly associated with nonhealing postlaparoscopic wound infections, causing outbreaks or sporadic cases worldwide. Purpose: We retrospectively studied the occurrence of nontuberculous mycobacterium (NTM from PSIs following LS that did not respond to antibiotics used for pyogenic infections and having sterile routine aerobic cultures and their antimicrobial susceptibility pattern to guide proper management. Methods: The study was done in a tertiary care hospital of Eastern India over a 1-year period which included PSI cases with delayed onset not responding to antibiotics, following different types of LS. Pus/discharge from 32 patients was collected and examined for isolation and identification of the causative agents. Gram stain and Ziehl–Neelsen staining methods were used for direct examination. Culture media included blood agar, Robertson's cooked meat broth, MacConkey agar, and Lowenstein–Jensen medium. Isolates from the cases were identified using biochemical tests or molecular methods and studied the antimicrobial susceptibility pattern by the standard microbiologic procedures. Results: Mycobacterium abscessus (13 and Mycobacterium fortuitum (2 were isolated from 15 serosanguinous drainage obtained from 32 cases by routine microbiological techniques. All isolates analyzed for antimicrobial susceptibility pattern were highly sensitive to clarithromycin (93.3%, amikacin (93.3%, and imipenem (80% but were variable to ciprofloxacin, ofloxacin, and linezolid. Conclusions: Our present study shows frequent association of

    The clinical and epidemiologic characteristics of pediatric sporotrichosis are poorly understood. To describe the incidence and clinical characteristics of cases of sporotrichosis in children 14 years of age and younger reported in Abancay from 2004 to 2011, stratified according to age. We performed a retrospective review of pediatric patients 14 years of age and younger who were diagnosed with sporotrichosis in a referral center at Abancay, a poor area located in the south central highlands of Peru, to estimate the incidence rates (per 100,000 person-years) according to age and sporotrichosis type (lymphocutaneous and fixed), and clinical characteristics of these patients. Of the 240 pediatric cases identified, 131 (54.6%) were male. The median age at baseline was 6 years. The mean incidence rate was 81.4 cases per 100,000 person-years for the period from 2004 to 2011, and was highest among children ranging in age from 5-9 years. The incidence of lymphocutaneous sporotrichosis and fixed sporotrichosis was 55 and 27 cases per 100,000 person-years, respectively, and the face was the most commonly affected anatomic site. Ninety-six of the 240 patients (40%) reported previous contact with cats, and 46 (19.2%) had a clear history of traumatic inoculation with plant material. The therapeutic response to treatment with potassium iodide was satisfactory. In this retrospective study, we described a high incidence of sporotrichosis in children in the south central highlands of Peru, which increased with age. Lymphocutaneous sporotrichosis was the more common type with an incidence rate twice that of the fixed type. The face was the most commonly affected anatomic site, and infection appeared to be acquired predominantly through contact with cats. © 2017 The International Society of Dermatology.

    Benzodiazepine use is a risk factor for the development of delirium in adult intensive care unit (ICU) patients. Suvorexant is an alternative to benzodiazepines to induce sleep, but the incidence of delirium in critically ill patients is unknown. We undertook this retrospective study to investigate the incidence of delirium in patients who receive suvorexant in the ICU. This retrospective cohort study was conducted in a closed 12-bed ICU at a tertiary teaching hospital. Patients admitted to the ICU for 72 h or longer between January and June 2015 were evaluated for delirium using the Confusion Assessment Method for the Intensive Care Unit tool. We evaluated the incidence of delirium in patients who received suvorexant and those who did not. To adjust for confounding factors, multivariable logistic regression analysis was conducted. Study subjects included 118 patients, with a median age of 72 years and a median Acute Physiology and Chronic Health Evaluation II score of 18 points. Eighty-two patients (69.5%) were admitted after cardiovascular surgery. In the suvorexant group, there were fewer post-cardiovascular surgical patients and more medical patients. The duration of mechanical ventilation during ICU stay was longer in the suvorexant group, and sedatives and sleep inducers other than suvorexant were used more frequently in the suvorexant group. The incidence of delirium was 43.8% in the suvorexant group and 58.8% in the non-suvorexant group (P = 0.149). After adjustment for risk factors using multivariable logistic regression analysis, suvorexant was associated with a lower incidence of delirium (odds ratio = 0.23, 95% confidence interval: 0.07-0.73; P = 0.012). Suvorexant was associated with decreased odds of transitioning to delirium in critically ill patients. The use of suvorexant may lower the incidence of delirium in ICU patients. Future prospective studies are warranted. © 2018 Japanese Psychogeriatric Society.

    Computed tomographic (CT) studies evaluating the relevance of individual CT features of apical infection in maxillary cheek teeth are lacking. To study the prevalence and relationship of single CT features in horses with and without clinical evidence of apical infection in maxillary cheek teeth. Retrospective case-control study. Multislice CT scans of the head of 49 horses were evaluated retrospectively. Changes of the infundibulum, pulp, root, lamina dura, periodontal space and alveolar bone in maxillary cheek teeth were recorded. Single CT changes were much more prevalent in the 28 horses with clinical signs. However, infundibular changes and a nondetectable lamina dura were also common in the 21 horses without clinical evidence of apical infection. Computed tomographic abnormalities of the pulp, root, periapical bone and periodontal space and the presence of a tooth fracture were significantly related. Infundibular changes were not associated with other CT signs of apical infection. Although nondetectable lamina dura was the most frequent CT change in all teeth in both studied groups, it was most commonly a solitary feature in otherwise normal teeth. Apical infections, defined as ≥3 CT changes, occurred mainly in the 108/208, 109/209 and 110/210 (Triadan numbers) and were found only in horses with clinical evidence of apical infection, except in one horse without clinical signs that had one affected root. Combined CT changes of the pulp, root, lamina dura, periapical bone and periodontal space and the presence of a tooth fracture appear to be reliable features to diagnose apical infection in maxillary cheek teeth. As a solitary feature, a nondetectable lamina dura should be interpreted cautiously and may even be considered normal due to its minor thickness and/or too low resolution of the imaging modality. © 2013 EVJ Ltd.

    The purpose of this study was to assess the efficacy and safety of cetuximab plus platinum-based chemotherapy for patients specifically diagnosed with recurrent or metastatic oral squamous cell carcinoma (OSCC). We conducted a multicenter retrospective observational study of patients who underwent first-line cetuximab plus platinum-based chemotherapy between December 2012 and June 2015. 65 patients received weekly cetuximab (week 1, 400 mg/m 2 ; subsequent weeks, 250 mg/m 2 ) plus a maximum of six 3-weekly cycles of cisplatin (80 or 100 mg/m 2 , day 1) or carboplatin (at an area under the curve of 5 mg/mL/min as a 1-h intravenous infusion on day 1) and 5-fluorouracil (800 or 1000 mg/m 2 /day, days 1-4). Patients with stable disease who received cetuximab plus platinum-based chemotherapy continued to receive cetuximab until disease progression or unacceptable toxicities, whichever occurred first. The median follow-up was 10.5 (range 1.2-34.2) months. The best overall response and the disease control rates were 46.2 and 67.7%, respectively. The median overall survival and progression-free survival rates were 12.1 and 7.8 months, respectively. The most common grades 3-4 adverse events were skin rash (9.2%) followed by leukopenia (6.2%). None of the adverse events were fatal. The results of our multicenter retrospective study, which was the largest of its kind to date, suggest that first-line cetuximab plus platinum-based chemotherapy is suitable and well-tolerated for the systemic therapy of recurrent or metastatic OSCC.

    Full Text Available Introduction: Oral lichen planus (OLP is a relatively common inflammatory mucocutaneous disorder that frequently involves the oral mucosa. The clinical presentation of OLP ranges from mild painless white keratotic lesions to painful erosions and ulcerations. An important complication of OLP is the development of oral squamous cell carcinoma, which led the World Health Organization (WHO to classify OLP as a potentially malignant disorder. The demographic and clinical characteristics of OLP have been well-described in several relatively large series from developed countries, whereas such series from developing countries are rare. Objective: The objective of this retrospective study was to investigate the epidemiological and clinical characteristics of 128 OLP patients in rural population of India. Materials and Methods: In this study, the diagnostic criteria proposed by van der Meij et al. in 2003 based on the WHO definition of OLP were used to identify cases. Results: In 128 patients, M:F ratio was 1.61:1. The buccal mucosa was the most common site (88.20%. White lichen was seen in 83.59% and red lichen in 16.40% cases. Reticular type of OLP was the most common form (83.5% followed by erosive (15.6% and atrophic OLP (0.78%. The incidence of systemic diseases included hypertension (11%, diabetes mellitus (2.4%, and hypothyroidism (0.78%. Histopathologically epithelial dysplasia was present in 4 cases. Conclusion: Most of the characteristics are consistent with previous studies with differences in few. Lichen planus is a chronic disease where treatment is directed to control of symptoms. Long-term follow-up is essential to monitor for symptomatic flare ups and possible malignant transformation.

    Full Text Available Objectives and importance: Paramedics have high rates of occupational injury and fatality. The objective of this study is to describe their specific risks of violence-related injury. Study type: This retrospective cohort study is an examination of retrospective data provided by Safe Work Australia (SWA. Methods: An examination of the 300 cases of serious claims of injury related to assaults, violence, harassment and bullying that occurred among individuals identified as ambulance officers and paramedics in Australia from 2001 to 2014. Paramedic risks likely vary by exposures such as hours worked and call volume. To examine how those exposures may influence risk, the available data were used to estimate rates based on hours worked and call volume. Results: The data show that, for serious injuries among paramedics in Australia between 2001 and 2014, the total number of violence-related cases increased from 5 to 40 per year; the number of cases of injury secondary to assault tripled from 10 to 30; and the rate of cases by call volume doubled from 6 to 12. The cost of these injuries was approximately AUD$250 000 for the year 2013–14. The median time at work lost per individual case of ‘work-related harassment and/or workplace bullying’ was 9.6 weeks. Although females comprised 32% of the paramedic workforce, they were the victims in 42% of cases of exposure to violence and 40% of harassment cases. Conclusions: Although anecdotal reports indicate that some interventions have been attempted, violence against paramedics continues to be a growing problem in Australia. The data presented in this study allow for a better understanding of the problem and can support efforts by ambulance service administrators, physicians, paramedics and university researchers to work together to develop and publish evidence based, cost-effective solutions to reduce the risk of workplace violence. Effective solutions will likely be multifaceted and include training

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

    Stroke after coronary by-pass grafting (CABG) is often disabling. The incidence of ischemic stroke may approach 3% to 5%. Several risk factors have been identified including previous history of stroke, prolonged cardiopulmonary bypass time, and postoperative atrial fibrillation. Objective was to determine the incidence and risk factors of neurological deficit after open heart surgery. Retrospective study was done during the period 1992-1995 at the King Khalid University Hospital, Riyadh, Saudi Arabia. There were 350 patients who were subjected to (CABG), 10 patients (2.8%) found to suffer from cerebrovascular accidents (CVA) following open-heart surgery. In 8 patients, the complaint lasted more than 24 hours (stroke), while 2 patients developed transient ischemic attacks (TIA). Five factors were found to be associated with increased risk of post cardiac surgery CVA. These factors are postoperative atrial fibrillation, carotid bruit, past history of heart failure, past history of CVA and smoking. The authors concluded that it is necessary to start a prospective study to verify the area of improvement with regards to technique, selection of patients and mode of perfusion during cardiopulmonary bypass (CPB) Arabia.

    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.

    This study aimed to determine the prevalence rate of knee osteoarthritis (OA) and the risk factors for OA in hospitalized elderly patients. We conducted this retrospective study in elderly patients (aged 65 years and older) who were hospitalized in the Geriatric Ward of General Hospital of Guangzhou Military Command of the People's Liberation Army between January 2011 and June 2013, including general condition, present history, past history, physical examination, X-ray results, and disease diagnosis. The prevalence, awareness, and treatment rates of knee OA in hospitalized elderly patients were calculated. Risk factors were computed using multiple logistic regression analysis. Of a total of 267 (17.4%) hospitalized elderly patients diagnosed with knee OA, the prevalence rate of OA was 9.95% in males and 37.76% in females. The rate of awareness among those with OA was 51.68%; the rate of treatment was 83.33%; and the rate of control was 77.39%. The medical expenses for both females (1143±315 yuan month-1) and males (1192±357 yuan month-1) in knee OA patients are higher than that of the non-knee OA group (989±274 yuan month-1, 1038±295 yuan month-1). The risk factors for knee OA include gender (OR=2.448), age (OR=1.124), transportation mode (OR= 8.972), exercise (OR=7.374), bowel evacuation position (OR=5.767), family history of knee OA (OR=2.195), and body mass index (OR=2.469). The prevalence of knee OA is unexpectedly high in hospitalized elderly patients, and the rates of awareness and treatment are less than desirable. Prevention and control measures should be taken in patients with concomitant risk factors.

    A protective effect of excessive body mass index (BMI) on mortality or functional outcome in patients with stroke is not well established in the Asian population. This study aimed to explore whether obese patients with stroke have advantages for functional improvement in Japanese rehabilitation wards. This retrospective cohort study included consecutive patients with stroke admitted and discharged from convalescent rehabilitation wards between 2011 and 2015. Demographic data, BMI, Functional Independence Measure (FIM) score, and nutritional status were analyzed. Participants were classified into 4 groups according to BMI (underweight stroke may have some advantages for functional recovery in rehabilitation wards. Copyright © 2015 National Stroke Association.

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

    External cephalic version (ECV) reduces the rate of elective cesarean sections as a result of breech presentation. Several studies have shown that not all eligible women undergo an ECV attempt. The aim of this study was to evaluate the implementation of ECV in the Netherlands and to explain variation in implementation rates with hospital characteristics and individual factors. We invited 40 hospitals to participate in this retrospective cohort study. We reviewed hospital charts for all singleton breech deliveries from 36 weeks' gestation and onwards between January 2008 and December 2009. We documented whether an ECV attempt was performed, reasons for not performing an attempt, mode of delivery, and hospital characteristics. We included 4,770 women from 36 hospitals. ECV was performed in 2,443 women (62.2% of eligible women, range 8.2-83.6% in different hospitals). Implementation rates were higher in teaching hospitals, hospitals with special office hours for ECV, larger obstetric units, and hospitals located in larger cities. Suboptimal implementation was mainly caused by health care providers who did not offer ECV. ECV implementation rates vary widely among hospitals. Suboptimal implementation is mostly caused by the care provider not offering the treatment and secondly due to women not opting for the offered attempt. A prerequisite for designing a proper implementation strategy is a detailed understanding of the exact reasons for not offering and not opting for ECV. © 2014 Wiley Periodicals, Inc.

    Some studies suggest that thrombotic thrombocytopenic purpura (TTP) occurs more often in African Americans. However there is low evidence for this in the literature. The aim of our study was to describe the clinical and biological characteristics of TTP in the Afro-Caribbean population of Martinique. We retrospectively analysed all patients with TTP diagnosed at the Fort-de-France hospital between 2008, January 1st and 2015, December 31st. Diagnosis was confirmed if ADAMTS-13 activity was<10 %. Ten patients were included, corresponding to an average annual incidence of 3.2 cases/year/million individuals. None of the patient presented with the association of the five characteristic features of TTP. Microangiopathic haemolytic anaemia and severe peripheral thrombocytopenia (median: 13G/L) was the main presentation leading to diagnosis. There was no kidney involvement in 90 % of all patients, but severe neurological manifestations occurred in 70 %. Classical management including corticosteroids and plasma exchanges allowed clinical remission in 6 out of the 10 cases. If necessary, rituximab or cyclophosphamide was used. The overall survival rate was 90 %. In Martinique, the incidence of TTP is twice that reported in similar studies in France. Clinical manifestations seem to differ by more common and more severe neurological involvement. Mortality is low, in part, due to optimal care.

    Full Text Available Excess weight and obesity have become a serious problem in adult men of reproductive age throughout the world. The purpose of this retrospective study was to assess the relationships between body mass index and sperm quality in subfertile couples in a Chinese Han population. Sperm analyses were performed and demographic data collected from 2384 male partners in subfertile couples who visited a reproductive medical center for treatment and preconception counseling. The subjects were classified into four groups according to their body mass index: underweight, normal, overweight, and obese. Of these subjects, 918 (38.3% had a body mass index of >25.0 kg m−0 2 . No significant differences were found between the four groups with respect to age, occupation, level of education, smoking status, alcohol use, duration of sexual abstinence, or the collection time of year for sperm. The results clearly indicated lower sperm quality (total sperm count, sperm concentration, motile sperm, relative amounts of type A motility, and progressive motility sperm [A + B] in overweight and obese participants than in those with normal body mass index. Normal sperm morphology and sperm volume showed no clear difference between the four groups. This study indicates that body mass index has a negative effect on sperm quality in men of subfertile couples in a Northern Chinese population. Further study should be performed to investigate the relationship between body mass index and sperm quality in a larger population.

    Recovery, or functional remission, represents the ultimate treatment goal in schizophrenia. Despite its importance, a standardized definition of remission is still lacking, thus reported rates significantly vary across studies. Moreover, the effects of rehabilitative interventions on recovery have not been thoroughly investigated. This study aimed to evaluate recovery in a sample of patients with chronic schizophrenia engaged in rehabilitation programs and to explore contributing factors, with a focus on sociocognitive rehabilitative interventions. Data from 104 patients with schizophrenia treated either with a standard rehabilitation program, including cognitive remediation (n = 46), or the latter plus a specific sociocognitive intervention (n = 58), and assessed for psychopathology, cognition, social cognition, and Quality of Life Scale, were retrospectively analyzed for this study. Recovery, evaluated with the Quality of Life Scale, was achieved by 56.76% of patients in our sample. While no effects were observed for clinical, cognitive, or sociocognitive variables, participation in the sociocognitive rehabilitative interventions was positively associated with recovery. Our results indicate that high rates of recovery can be achieved in patients treated with psychosocial interventions and suggest that rehabilitative programs targeting social cognition may further facilitate the process of recovery. If confirmed, these results may have relevant implications for daily clinical practice and service provision, allowing clinicians to develop and optimize specific rehabilitation programs in order to promote recovery. © 2017 The Authors.

    Bacterial infections present a major challenge in equine medicine. Therapy should be based on bacteriological diagnosis to successfully minimize the increasing number of infections caused by multidrug-resistant bacteria. The present study is a retrospective analysis of bacteriological results from purulent infections in horses admitted at the University Equine Clinic of Bern from 2004 to 2008. From 378 samples analyzed, 557 isolates were identified, of which Staphylococcus aureus, Streptococcus equi subsp. zooepidemicus and coliforms were the most common. Special attention was paid to infections with methicillin-resistant S. aureus (MRSA) ST398 and a non-MRSA, multidrug-resistant S. aureus clone ST1 (BERN100). Screening of newly-admitted horses showed that 2.2 % were carriers of MRSA. Consequent hygiene measures taken at the Clinic helped to overcome a MRSA outbreak and decrease the number of MRSA infections.

    Study delay and attrition are major concerns in higher education. They cost time and effort, and threaten the availability of higher qualified professionals. Knowing early what factors contribute to delay and attrition may help prevent this. The aim of this study was to examine whether student characteristics, including a literature study report grade as a proxy of cognitive abilities, predicted study success in a dual advanced nurse practitioner education program. Retrospective cohort study, including all 214 students who between September 2009 and September 2015 started the two-year program at the HAN University of Applied Sciences in Nijmegen, the Netherlands. Study success was defined as having completed the program within the envisaged period. Variables examined included: age, gender, previous education (bachelor's degree or in-service training in nursing), work setting (general health, mental health, public health, or nursing home care), and literature study report grade (from 1 to 10). A hierarchical logistic regression analysis was performed. Most students were female (80%), had a bachelor's degree in nursing (67%), and were employed in a general healthcare setting (58%). Mean age was 40.5years (SD 9.4). One hundred thirty-seven students (64%) had study success. Being employed in a general healthcare setting (p≤0.004) and a higher literature study report grade (p=0.001) were associated with a higher study success rate. In advanced nurse practitioner education, study success rate seems associated with the student's cognitive abilities and work field. It might be worthwhile to identify students 'at risk of failure' before the start of the program and offer them extra support. Copyright © 2017 Elsevier Ltd. All rights reserved.

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

    Background To determine the effect of human milk, maternal and donor, on in-hospital growth of very low birthweight (VLBW) infants. We performed a retrospective cohort study comparing in-hospital growth in VLBW infants by proportion of human milk diet, including subgroup analysis by maternal or donor milk type. Primary outcome was change in weight z-score from birth to hospital discharge. Methods Retrospective cohort study. Results 171 infants with median gestational age 27 weeks (IQR 25.4, 28.9) and median birthweight 899 g (IQR 724, 1064) were included. 97% of infants received human milk, 51% received > 75% of all enteral intake as human milk. 16% of infants were small-for-gestational age (SGA, 75% human milk had a greater negative change in weight z-score from birth to discharge compared to infants receiving human milk fortifier was related to human milk intake (p = 0.04). Among infants receiving > 75% human milk, there was no significant difference in change in weight z-score by milk type (donor −0.84, maternal −0.56, mixed −0.45, p = 0.54). Infants receiving >75% donor milk had higher rates of SGA status at discharge than those fed maternal or mixed milk (56% vs. 35% (maternal), 21% (mixed), p = 0.08). Conclusions VLBW infants can grow appropriately when fed predominantly fortified human milk. However, VLBW infants fed >75% human milk are at greater risk of poor growth than those fed less human milk. This risk may be highest in those fed predominantly donor human milk. PMID:22900590

    Increasing numbers of individuals are being initiated on home mechanical ventilation, including noninvasive (bi-level) and invasive mechanical ventilation delivered via tracheostomy due to chronic respiratory failure to enable symptom management and promote quality of life. Given the high care needs of these individuals, a better understanding of the indications for home mechanical ventilation, and health-care utilization is needed. We performed a retrospective cohort study using provincial health administrative data from Ontario, Canada (population ∼13,000,000). Home mechanical ventilation users were characterized using health administrative data to determine the indications for home mechanical ventilation, the need for acute care at the time of ventilation approval, and their health service use and mortality rates following approval. The annual incidence of home mechanical ventilation approval rose from 1.8/100,000 in 2000 to 5.0/100,000 in 2012, or an annual increase of approximately 0.3/100,000 persons/y. The leading indications were neuromuscular disease, thoracic restriction, and COPD. The indication for the remainder could not be determined due to limitations of the administrative databases. Of the 4,670 individuals, 23.0% commenced home mechanical ventilation following an acute care hospitalization. Among individuals who survived at least 1 y, fewer required hospitalization in the year that followed home mechanical ventilation approval (29.9% vs 39.8%) as compared with the year prior. Utilization of home mechanical ventilation is increasing in Ontario, Canada, and further study is needed to clarify the factors contributing to this and to further optimize utilization of health-care resources.

    Full Text Available BACKGROUND Thyroid carcinoma accounts for less than 1% of cancer cases. In the Indian subcontinent, thyroid carcinoma exhibits a varied disease profile and geographic differences in the pattern of cancer, the knowledge of which impacts a more favourable clinical outcome. The present study aims to profile Thyroid carcinoma in areas of age, gender, geographic domicile, morphology & clinical features and referral paradigm of cases in King George Hospital, Visakhapatnam, the tertiary referral hospital for coastal Andhra Pradesh. METHODS & MATERIALS The Retrospective Study 1988-2004 includes 188 patients who attended Department of Nuclear Medicine for pre & postoperative nuclear scan, thyroid carcinoma treatment protocol, whose clinical features, relevant laboratory data, histopathological reports & prognosis were analysed. RESULTS Papillary thyroid carcinoma was present in 79% and Follicular thyroid carcinoma in 19%, Anaplastic & Medullary Thyroid Carcinoma in 2% of cases (n=188, male to female ratio 1:0.62. Coastal city of Visakhapatnam recorded highest 59% of cases who were in their 3rd and 4th decades. West Godavari District had lowest at 5%. Clinical presentation of cases of Thyroid carcinoma as a Nodule (61% which was the most common form lead to maximum number of referrals (n=82 from the Department of Surgery, King George Hospital. CONCLUSION In coastal Andhra Pradesh, papillary thyroid carcinoma was the most dominant form. Women were more affected than men. Painless thyroid nodule was the most common clinical feature. Coastal city of Visakhapatnam recorded highest number of cases and maximum referrals were from Department of Surgery.

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

    Symptomatic extramedullary hematopoiesis (EH) is a rare but potentially severe phenomenon which occurs in β-thalassemia. There are no treatment guidelines. Retrospective single centre study including the cases of symptomatic EH encountered between 1997 and 2014 in a unit specialised in red blood cell genetic disorders. Description of clinical, biological and radiological characteristics of the patients, treatments received, and outcomes. Among 182 β-thalassemia patients followed during the study period, 7 cases of symptomatic EH were diagnosed. They were 5 men and 2 women, and their mean age was 37 years. Four patients were splenectomised, two patients were regularly transfused, and four patients had already received erythropoietin. EH was localised in intravertebral areas and responsible for dorsal spinal cord compression in 5 patients, in paravertebral dorsal area in 1 patient, and in presacral area in 1 patient. The mean hemoglobin level at diagnosis was 7.9 g/dL. Treatment administered included: red cell transfusion in 6 cases, associated with hydroxyurea in 5 cases and/or radiotherapy in 3 patients. One patient was treated with surgery and HU. After a median follow-up of 41 months, clinical recovery was complete in 2 patients and partial in 5 patients. EH must be suspected in β-thalassemia in patients presenting clinical signs of organ compression, and a typical radiological aspect. The functional prognosis depends on the rapidity of treatment, which includes red blood cell transfusion, hydroxyurea, radiotherapy, and rarely surgery. Long-term outcome is uncertain.

    Full Text Available Introduction and objective: Acute epiglottitis is an inflammation of the epiglottis and other adjacent structures that can produce severe obstruction of the airway. Our objective is to know the clinical-epidemiological characteristics of acute epiglottitis in a Region of the north of Spain. Method: Retrospective descriptive study of all patients diagnosed with acute epiglottitis from January 1992 to April 2015 in the Region of Cantabria (Spain. Results: Fifty patients were included in our study, aged between 1 and 80 years, of whom 40 were men and 10 were women. Only one of them was a pediatric patient. 2.7 cases / year were diagnosed, with an incidence of 0.5 cases per 100000 habitants per year. Two patients had Down syndrome. The main symptom was odynophagia (88% followed by dyspnea (56% and voice alteration (52%. Nine patients required a stay in Intensive Care. Four patients required orotracheal intubation; five needed an emergency tracheotomy. Seven patients had serious complications, one of them with severe neurological damage. None of them died because of epiglottitis. Conclusions: Acute epiglottitis is a rare but serious disease and, therefore, requires early treatment to avoid complications. We have observed an almost total disappearance of epiglottitis in pediatric patients in our region, which is explained by the introduction in the vaccination calendar of immunization against Haemophilus influenzae.

    Ballet dancers are high-performance athletes who are particularly susceptible to a wide variety of musculoskeletal injuries. However, they are relatively understudied, and data on their injury rates are lacking. This retrospective study features the largest aggregate data on professional ballet dancers to date and aims to identify the most common diagnoses and areas of injury in this unique population to better direct preventative and clinical practices. The study encompassed a 10-year period from January 2000 to December 2010 of dancers from a single company. Data regarding the dancers' age, gender, location of injury, and diagnosis were collected from workers' compensation claims, company records, and medical records maintained by the treating doctors. These were analyzed to determine metrics on injury incidence, frequency, and diagnosis. Over the 10-year span, 574 injuries occurred. There were approximately 52 dancers per year for a total of 153 who danced at least one complete season during the study period. The average age was 27, and 53% were female. Given turnover with retirement and replacements, the total number of dancer-years was 520, indicating an injury incidence per annum of 1.10 (574 injuries per 520 dancer-years). The most common locations of injury were foot and ankle and the lumbar spine, with the three most common diagnoses making up greater than a third (37%) of the total. As the current largest study in professional ballet, the findings set the benchmark metrics for musculoskeletal injury to the foot, ankle, and lumbar spine sites. Future studies should aim to identify injury risk factors and modalities for prevention of these injuries.

    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

    Full Text Available BACKGROUND This study aimed at assessing the outcome of laparoscopic cholecystectomy (LC by determining the frequency of complications, especially of bile duct injuries. MATERIALS AND METHODS The case files of all patients undergoing laparoscopic cholecystectomy between January 2008 and December 2016 at Government General Hospital, Kakinada were retrospectively analysed. We evaluated the data according to outcome measures, such as bile duct injury, morbidity, mortality and numbers of patients whose resections had to be converted from laparoscopic to open. RESULTS During the eight years (January 2008 and December 2016, 336 patients underwent LC for chronic cholecystitis (CC, of whom 22 (6.5% developed complications. Among those who developed complications, two patients had major bile duct injuries (0.4%; 43 other patients (12.8% had planned laparoscopic operations converted to open cholecystectomy intra-operatively. None of the patients in this study died as a result of LC. CONCLUSION Bile duct injury is a major complication of LC. Anatomical anomalies, local pathology, and poor surgical techniques are the main factors responsible. The two patients who had severe common bile duct injury in this study had major anatomical anomalies that were only recognized during surgery.

    Coeliac disease is a chronic enteropathy characterized by an increased mortality caused by its complications, mainly refractory coeliac disease, small bowel carcinoma and abdominal lymphoma. Aim of the study was to study the epidemiology of complications in patients with coeliac disease. Retrospective multicenter case-control study based on collection of clinical and laboratory data. The incidence of complicated coeliac disease was studied among coeliac patients directly diagnosed in four Italian centres. Patients referred to these centres after a diagnosis of coeliac disease and/or complicated coeliac disease in other hospitals were therefore excluded. Between 1/1999 and 10/2011, 1840 adult coeliac patients were followed up for 7364.3 person-years. Fourteen developed complications. Since five patients died, at the end of the observation period (10/2011), the prevalence of complicated coeliac disease was 9/1835 (1/204, 0.49%, 95% CI 0.2-0.9%). The annual incidence of complicated coeliac disease in the study period was 14/7364 (0.2%, 95% CI 0.1-0.31%). Although complications tend to occur soon after the diagnosis of coeliac disease, Kaplan-Meier curve analysis showed that they can actually occur at any time after the diagnosis of coeliac disease. Complications of coeliac disease in our cohort were quite rare, though characterised by a very high mortality. Copyright © 2013 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

    2014-09-01

    The Bristol Stool Chart (BSC) allows patients to identify their stool form using seven different images with accompanying written descriptors. Stool form was found to correlate better than stool frequency with whole-gut transit as measured by a radio-opaque marker study. This score is widely used in order to verify the presence of a constipation and to evaluate the therapeutic impact of various treatments. In our clinical practice, we was strongly surprised by the facility and the great precision of the patients to report their stool form, meaning that they usually and daily verify these stools. We wanted to precise the goals of a such attitude. Two questionnaires were proposed to healthy and voluntary subjects. Q1 was supposedly presented in order to verify the sensibility of a French version of BSC in a healthy population. Thus, Q1 precised the difficulties or not to understand pictures and written descriptors, asked about exhaustive analysis by means of BSC of stool form and bowel condition. All subjects with history of ano-rectal disorders or specific treatment for bowel dysfunction were excluded. After Q1 fulfilled, Q2 was proposed to the subjects. Q2 was designed to precise the goals of the patient when he look at his stool and the frequency of such an investigation. Finally a specific question concerning the subject opinion about this behavior in terms of bothersome, shame, or metaphysic interrogation. Eighty-five healthy subjects were recruited (42 female and 43 male). Mean age was 37.2 (sd = 15.7). Mean score of BCS was 2.07 (sd =1.05) (2.07 for female and 1.81 for male, P = 0.22). Number of categories of stool form was only 1 in 40%, 2 categories in 31%, 3 in 19%, 4 in 10%. Presence of a constipation defined by category 1 or 2 was found in 17% (23% in F, 12% in M, P = 0.075). Precision of BSC was noted as excellent in 68%, moderated in 18% and poor in 14%. BSC was considered as easy to use in 75%. Frequency of inspection of feces was systematic for 37%, 1

Two groups were established; the first, NEDN with laser, and second, NEDN with radiofrequency. The number and types of complications reported in the case-series were counted, and their statistical differences determined. Results: The inclusion criteria were fulfilled by 643 of the medical charts. 26 complications were reported, the most common being radiculitis (n=12. Statistically significant differences were found between the complications occurring in the two groups (p=0.01. Conclusion: The number of complications showed statistically significant difference. The severity of the complications and adverse outcomes provide an argument for choosing one technology over the other. Training and the learning curve stage are important factors to be taken into account, to avoid complications.

    Recent years have seen a shift in perspective on Turner syndrome, as it is no longer considered a significant disability due to therapeutic advances. The delay of diagnosis and the underdiagnosis are common in Turner syndrome, especially because of the great phenotypic variability and lack of firm diagnostic criteria. Our first aim was to assess the clinical and the cytogenetic characteristics and growth rate in growth hormone (GH)-treated patients as compared to those with spontaneous growth. The second aim was to analyze the Y chromosomal sequences. We analyzed 45 patients diagnosed with Turner syndrome in Genetic Pathology Centre of Cluj Emergency Children's Hospital. We carried out a study of the clinical features, the correlations between the karyotype and the phenotype, and we also made a research of Y chromosome sequences. The average age at diagnosis was 8.9±5.4 years. A significant association was observed between the number of external phenotypical abnormalities and internal malformations ( r =0.45), particularly the cardiovascular ones ( r =0.44). Patients treated with GH showed improvement in growth rate, with final stature significantly better than in untreated patients; benefits following treatment were greater if diagnosis was made before the age of 5 years. Thirteen percent of patients experienced spontaneous and complete puberty, whereas 30% experienced incomplete puberty. Patients with the 45,X genotype had a greater stature deficit and a higher incidence of cardiac malformations, compared with patients with 45,X/46,XX mosaic karyotype. Y chromosome sequences were found in only one patient, who subsequently underwent gonadectomy. The importance of this study resides, to the best of our knowledge, in the fact that the largest group of patients in Romania was analyzed and assessed. To draw firm conclusions on the most valuable clinical indicators for Turner syndrome diagnosis in clinical practice, studies on large groups of patients should be

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

    A population-based observational study design was used to describe the epidemiology of intellectual disability in cerebral palsy (CP) in terms of clinical and neuroimaging associations, and to report the impact of intellectual disability on utilization of health services and length of survival. Population CP registry data were used to retrospectively assess the frequency of intellectual disability and strength of associations between intellectual disability and mobility, epilepsy, vision, hearing, communication, and neuroimaging patterns (n=1141). Data linkage was undertaken to assess usage of hospital inpatient and emergency department services. Survival analysis was performed in a 30-year birth cohort (n=3248). Intellectual disability, present in 45% of the cohort, was associated with non-ambulation (47% vs 8%), later walking (mean 2y 7mo vs 1y 9mo), hypotonic (8% vs 1%) or dyskinetic (9% vs 5%) CP, a quadriplegic pattern of motor impairment (42% vs 5%), epilepsy (52% vs 12%), more emergency and multi-day hospital admissions, and reduced 35-year survival (96% vs 71%). Grey matter injuries (13% vs 6%), malformations (18% vs 6%), and miscellaneous neuroimaging patterns (12% vs 4%) were more common in people with intellectual disability. Intellectual disability adds substantially to the overall medical complexity in CP and may increase health and mortality disparities. Cerebral maldevelopments and grey matter injuries are associated with higher intellectual disability rates. Health care is more 'crisis-driven' and 'reactive' in children with co-occurring intellectual disability. Length of survival is reduced in individuals with CP and co-occurring intellectual disability. © 2018 Mac Keith Press.

    Full Text Available Since 2010, WHO has recommended oral cholera vaccines as an additional strategy for cholera control. During a cholera episode, pregnant women are at high risk of complications, and the risk of fetal death has been reported to be 2-36%. Due to a lack of safety data, pregnant women have been excluded from most cholera vaccination campaigns. In 2012, reactive campaigns using the bivalent killed whole-cell oral cholera vaccine (BivWC, included all people living in the targeted areas aged ≥ 1 year regardless of pregnancy status, were implemented in Guinea. We aimed to determine whether there was a difference in pregnancy outcomes between vaccinated and non-vaccinated pregnant women.From 11 November to 4 December 2013, we conducted a retrospective cohort study in Boffa prefecture among women who were pregnant in 2012 during or after the vaccination campaign. The primary outcome was pregnancy loss, as reported by the mother, and fetal malformations, after clinical examination. Primary exposure was the intake of the BivWC vaccine (Shanchol during pregnancy, as determined by a vaccination card or oral history. We compared the risk of pregnancy loss between vaccinated and non-vaccinated women through binomial regression analysis. A total of 2,494 pregnancies were included in the analysis. The crude incidence of pregnancy loss was 3.7% (95%CI 2.7-4.8 for fetuses exposed to BivWC vaccine and 2.6% (0.7-4.5 for non-exposed fetuses. The incidence of malformation was 0.6% (0.1-1.0 and 1.2% (0.0-2.5 in BivWC-exposed and non-exposed fetuses, respectively. In both crude and adjusted analyses, fetal exposure to BivWC was not significantly associated with pregnancy loss (adjusted risk ratio (aRR = 1.09 [95%CI: 0.5-2.25], p = 0.818 or malformations (aRR = 0.50 [95%CI: 0.13-1.91], p = 0.314.In this large retrospective cohort study, we found no association between fetal exposure to BivWC and risk of pregnancy loss or malformation.

    Obesity is a serious and rapidly growing health problem worldwide. Few therapies are available beyond diet, exercise and bariatric surgery. A previously approved medication, sibutramine, has been withdrawn from the market due to concerns over the potential of increased risk of cardiovascular (CV) events, based on a phase IV clinical trial that included only individuals at high risk for CV events. The aim of the study was to compare sibutramine users and matched non-users on rates of CV events, both overall and stratified by whether the patient qualified for on-label sibutramine use, using data from real-life clinical practice. A retrospective cohort was constructed from electronic medical record data from physician office practices (mostly primary care) in the UK and Germany, using the LifeLink™ database from IMS Health Incorporated. For patients with at least one physician visit in which sibutramine was prescribed between 1 April 1999 and 31 October 2008, the date of their first such prescription was their index date. Users and non-users were matched 1 : 1 on index date (within 30 days), sex, age group (six categories), Charlson Comorbidity Index and evidence of obesity (high body mass index [BMI] or, if BMI was missing, diagnosis of obesity or very high weight relative to height). The resultant total samples analysed were 6186 in Germany and 7264 in the UK. User and non-user cohorts in the samples were compared according to the ratio of their crude incidence rates of acute myocardial infarction (AMI), stroke and either AMI or stroke per 1000 patient-years of follow-up. Cox regression analysis was used to compare the risk of CV events as a hazard ratio (HR) with 95% confidence intervals (CIs) between sibutramine user and non-user cohorts, controlling for label status and/or history of prior CV disease at baseline. The risk of AMI, stroke and either AMI or stroke was not higher among sibutramine users than comparable non-users of sibutramine in both Germany and

    Critical illness leads to increased endogenous production of carbon monoxide (CO) due to the induction of the stress-response enzyme, heme oxygenase-1 (HO-1). There is evidence for the cytoprotective and anti-inflammatory effects of CO based on animal studies. In critically ill patients after cardiothoracic surgery, low minimum and high maximum carboxyhemoglobin (COHb) levels were shown to be associated with increased mortality, which suggests that there is an 'optimal range' for HO-1 activity. Our study aimed to test whether this relationship between COHb and outcome exists in non-surgical ICU patients. We conducted a retrospective, observational study in a medical ICU at a university hospital in Vienna, Austria involving 868 critically ill patients. No interventions were undertaken. Arterial COHb was measured on admission and during the course of treatment in the ICU. The association between arterial COHb levels and ICU mortality was evaluated using bivariate tests and a logistic regression model. Minimum COHb levels were slightly lower in non-survivors compared to survivors (0.9%, 0.7% to 1.2% versus 1.2%, 0.9% to 1.5%; P=0.0001), and the average COHb levels were marginally lower in non-survivors compared to survivors (1.5%, 1.2% to 1.8% versus 1.6%, 1.4% to 1.9%, P=0.003). The multivariate logistic regression analysis revealed that the association between a low minimum COHb level and increased mortality was independent of the severity of illness and the type of organ failure. Critically ill patients surviving the admission to a medical ICU had slightly higher minimum and marginally higher average COHb levels when compared to non-survivors. Even though the observed differences are statistically significant, the minute margins would not qualify COHb as a predictive marker for ICU mortality.

    Full Text Available Abstract Background Delayed neuropsychological sequelae (DNS commonly occur after recovery from acute carbon monoxide (CO poisoning. The preventive role and the indications for hyperbaric oxygen therapy in the acute setting are still controversial. Early identification of patients at risk in the Emergency Department might permit an improvement in quality of care. We conducted a retrospective study to identify predictive risk factors for DNS development in the Emergency Department. Methods We retrospectively considered all CO-poisoned patients admitted to the Emergency Department of Careggi University General Hospital (Florence, Italy from 1992 to 2007. Patients were invited to participate in three follow-up visits at one, six and twelve months from hospital discharge. Clinical and biohumoral data were collected; univariate and multivariate analysis were performed to identify predictive risk factors for DNS. Results Three hundred forty seven patients were admitted to the Emergency Department for acute CO poisoning from 1992 to 2007; 141/347 patients participated in the follow-up visit at one month from hospital discharge. Thirty four/141 patients were diagnosed with DNS (24.1%. Five/34 patients previously diagnosed as having DNS presented to the follow-up visit at six months, reporting a complete recovery. The following variables (collected before or upon Emergency Department admission were associated to DNS development at one month from hospital discharge in the univariate analysis: CO exposure duration >6 hours, a Glasgow Coma Scale (GCS score Conclusions Our study identified several potential predictive risk factors for DNS. Treatment algorithms based on an appropriate risk-stratification of patients in the Emergency Department might reduce DNS incidence; however, more studies are needed. Adequate follow-up after hospital discharge, aimed at correct recognition of DNS, is also important.

    Full Text Available Abstract Background Cerebrovascular complications are severe events following orthotopic liver transplantation (OLT. This study aimed to observe the clinical and neuroimaging features and possible risk factors of in-hospital cerebrovascular complications in the patients who underwent OLT. Patients and methods We retrospectively reviewed 337 consecutive patients who underwent 358 OLTs. Cerebrovascular complications were determined by clinical and neuroimaging manifestations, and the possible risk factors were analyzed in the patients with intracranial hemorrhage. Results Ten of 337 (3.0% patients developed in-hospital cerebrovascular complications (8 cases experienced intracranial hemorrhage and 2 cases had cerebral infarction, and 6 of them died. The clinical presentations were similar to common stroke, but with rapid deterioration at early stage. The hematomas on brain CT scan were massive, irregular, multifocal and diffuse, and most of them were located at brain lobes and might enlarge or rebleed. Infarcts presented lacunar and multifocal lesions in basal gangliar but with possible hemorrhagic transformation. The patients with intracranial hemorrhage had older age and a more frequency of systemic infection than non-intracranial hemorrhage patients. (P = 0.011 and 0.029, respectively. Conclusion Posttransplant cerebrovascular complications have severe impact on outcome of the patients who received OLT. Older age and systemic infection may be the possible risk factors of in-hospital intracranial hemorrhage following OLT.

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

    Nowadays, the entire manufacturing process is based on the current GMPs, which emphasize the reproducibility of the process, and companies have a lot of recorded data about their processes. The establishment of the design space (DS) from retrospective data for a wet compression process. A design of experiments (DoE) with historical data from 4 years of industrial production has been carried out using the experimental factors as the results of the previous risk analysis and eight key parameters (quality specifications) that encompassed process and quality control data. Software Statgraphics 5.0 was applied, and data were processed to obtain eight DS as well as their safe and working ranges. Experience shows that it is possible to determine DS retrospectively, being the greatest difficulty in handling and processing of high amounts of data; however, the practicality of this study is very interesting as it let have the DS with minimal investment in experiments since actual production batch data are processed statistically.

    This study was a cephalometric evaluation of the growth changes in untreated subjects with minimal overbite at 4 time points during 4 developmental stages from the early mixed dentition to the permanent dentition, as well as from the prepubertal phase to young adulthood. A sample of 24 untreated subjects with minimal overbite (<1.5 mm) was selected retrospectively from the University of Michigan Growth Study and the Denver Child Growth Study. The sample was followed longitudinally from about 9 years of age through 17 years of age. Dentofacial changes at the 4 times (T1-T4), defined by the cervical vertebral maturation method, were analyzed on lateral cephalograms. Nonparametric statistical analysis was used for comparisons. Overbite on average increased by 2.3 mm during the overall observation period. Improvement occurred during the prepubertal interval (T1-T2; 2.4 mm), whereas no significant changes occurred in the pubertal and postpubertal stages. From prepubertal ages to young adulthood, the open-bite tendency improved in 91% of the subjects, with self-correction in 75%. Logistic regression analysis on the cephalometric variables at T1 with the value of overbite at T4 did not show a statistically significant correlation. Subjects with an open-bite tendency show improvement of their occlusal condition during the prepubertal stage, but there is no significant improvement after this. These results provide useful indications for appropriate orthodontic treatment timing for patients with an open-bite tendency. Copyright © 2014 American Association of Orthodontists.

    Background: The extent of association of human papilloma virus (HPV) in human conjunctival neoplasias has been debated in studies originating from different parts of the world, but no substantial evidence has been generated on Indian subjects. This prompted us to carry out a retrospective study on conjunctival neoplasias diagnosed over the past 12 years. Materials and Methods: Histopathological and immunohistochemical analysis of 65 specimens of ocular neoplasias and 30 normal controls diagnosed between 1991 and 2002 at a tertiary eye care hospital, was undertaken. Formalin-fixed, paraffin-embedded tissues were reviewed for confirming histopathological diagnosis, presence of koilocytosis and changes related to actinic keratosis. Immunohistochemical analysis was done using HPV-specific monoclonal antibodies. Clinicopathological correlation and the association of HPV antigen with the histopathological features were performed. Results: Out of the 65 cases analyzed, 35 were papillomas and 30 were ocular surface squamous neoplasias (OSSN). The mean age was 48 years with a male preponderance. Histologically, koilocytosis was observed in 17.1% of papillomas and 36.6% of OSSN. Actinic keratosis was present in 33% of OSSN. Immunohistochemically 17.1% conjunctival papillomas stained positive for HPV antigen, all cases of OSSN were negative for HPV. There was no correlation between koilocytosis or actinic keratosis and the detection of HPV antigen. Conclusions: The association between HPV and conjunctival neoplasias is variable in different geographical areas and also depends on the methods of detection used. This study warrants the need for applying more advanced techniques at a molecular level to determine the possible etiology of HPV in conjunctival neoplasias among Asian-Indians. PMID:17699945

We undertook a retrospective chart review and tested the hypothesis that tidal volume is a predictor of mortality in cardiothoracic (medical and surgical critical care patients receiving invasive mechanical ventilation. Independent predictors of mortality in our study included: type of surgery, albumin, H+, bilirubin, and fluid balance. In particular, it is important to note that cardiac, thoracic, and transplant surgical patients were associated with lower mortality. However, our study did not sample equally from The Berlin Definition of ARDS severity categories (mild, moderate, and severe hypoxemia. Although our study was not adequately powered to detect a difference in mortality between these groups, it will inform the development of a large prospective cohort study exploring the role of low tidal volume ventilation in cardiothoracic critically ill patients.

    Alopecia areata usually presents as patchy, nonscarring hair loss. It seems to be an immune mediated disease, whereas genetic predisposition, environmental and psychological triggers may be involved in its aetiology. To study the epidemiology, clinical aspects, associations, and treatment of alopecia areata in the paediatric population of Peadiatric Dermatology outpatients over a 9-year period. Some psychologic characteristics were also assessed. Descriptive and retrospective study of all newly diagnosed AA cases seen from January 2000 to December 2008 at the Hospital de São Marcos' Paediatric Dermatology Department. Fifteen patients with AA were interviewed for psycologic evaluation. Forty-eight cases (54% male/46% female) were identified. Mean age at presentation was 7.8 years. Family history of AA was reported in 10% of the cases, and in 25% there was a personal and/or family history of atopy. The majority of patients (82%) had mild disease and topical corticotherapy was the first-line treatment for limited AA. Fifty-four percent of these patients had a complete resolution of the lesions with treatment. Systemic treatment (corticosteroids and/or ciclosporin) was used in 71% of patients with extensive disease (more than 50% hair loss). Only one of these patients had a sustained clinical improvement after treatment. Twelve out of 15 respondents (80%) recalled stressful events preceding hair loss. Our findings are similar to those reported in other studies. Epidemiologic studies of AA are available in adulthood but there is a paucity of literature on children with AA. A holistic approach is important in the management of childhood AA as the disease can have a severe psychologic impact on an individual's well-being.

In a retrospective, case-control study, 275 women with Alzheimer’s disease (AD and 276 control patients from a hospital population were enrolled from July 2007 to December 2010. The AD patients presented with later menopause (P < 0.01, lower occurrence of surgical menopause (P < 0.04, reduced hormone-replacement therapy intake (P < 0.0001, and a longer reproductive life span (P < 0.01, compared to controls. No significant differences were found with respect to age at puberty, number of pregnancies, previous abortions, or contraceptive therapy. A higher education level appeared to have a protective role against the risk of developing AD. In women, menopause and hormone-replacement therapy can differentially modulate the clinical manifestations of AD, but these factors do not play a predictive role in its development.Keywords: Alzheimer’s disease, gender, menopause, hormone-replacement therapy, surgical menopause, education

    The aim of this study was to evaluate the precision of bimaxillary surgery performed to correct vertical maxillary excess, when the procedure is sequenced with mandibular surgery first or maxillary surgery first. Thirty-two patients, divided into two groups, were included in this retrospective study. Group 1 comprised patients who received bimaxillary surgery following the classical sequence with repositioning of the maxilla first. Patients in group 2 received bimaxillary surgery, but the mandible was operated on first. The precision of the maxillomandibular repositioning was determined by comparison of the digital prediction and postoperative tracings superimposed on the cranial base. The data were tabulated and analyzed statistically. In this sample, both surgical sequences provided adequate clinical accuracy. The classical sequence, repositioning the maxilla first, resulted in greater accuracy for A-point and the upper incisor edge vertical position. Repositioning the mandible first allowed greater precision in the vertical position of pogonion. In conclusion, although both surgical sequences may be used, repositioning the mandible first will result in greater imprecision in relation to the predictive tracing than repositioning the maxilla first. The classical sequence resulted in greater accuracy in the vertical position of the maxilla, which is key for aesthetics.

    Full Text Available Aim This article presents a retrospective study on the behavior of implants placed with split crest technique in lateroposterior maxillary class IV atrophy. Materials and Methods Subjects who underwent implant placement following split crest technique in the maxillary latero-posterior area were enrolled in the present retrospective study. After a mean period of 6.2 years of function implant survival and success rates were assessed. Moreover, radiographic examination was made on digital periapical radiographs and by means of a specific software. Bone level changes were measured as the difference between the peri-implants crestal bone level and the implants shoulder during the last patient’s visit recall examination. Results A total of 30 patients satisfied the inclusion criteria and were included in the study; the subjects were treated with 88 implants (64 transmucosal and 24 submerged. The observation period for all patients treated with split crest technique varied between 4 and 8 years (mean 6.2 years. The implants survival rate was 96.6% and the prostheses survival rate was 100%. Bone resorption ranged between 2.3 mm and 2.7 mm. Conclusion Implants inserted in conjunction with split crest technique seems to be a promising therapy with similar results as conventional implant surgery.

    Full Text Available Studies published from centers across India have reported different and contradicting patterns of glomerular disease. In this retrospective study, we report our experience from a Tertiary Care Center in Northwest India. A total of 702 renal biopsies performed between 2008 and 2013 were reviewed of which 80 were excluded from the study because of having insufficient records or if the biopsies were taken from an allograft. The study included 411 males (66.1 % and 211 females (33.9% with an age range of 12-70 years (mean 30.34 ± 7.04 years. Majority of the biopsies (93.9% showed some form of glomerulonephritis (GN, either primary (79.4% or secondary glomerular disease (SGD (14.5%. Minimal change disease (MCD was the most common type of primary GN (26.5% of primary GN, followed by membranous nephropathy (MN; 18.8% and focal and segmental glomerulosclerosis (FSGS; 13.2%. Lupus nephritis (LN was the most frequent SGD (52.2% of secondary GN. Amyloidosis was found in 41.1% and diabetic glomerulosclerosis in 4.4%. LN was also the second most common diagnosis in females after MCD, seen in 19.4% of females. MCD followed by membranoproliferative GN and diffuse proliferative GN were the most common entities in individuals <20 years of age. In the 20-39 years age group, MN was the most common pathology seen. MN was again the most common pathology seen in patients aged above 40 years followed by amyloidosis and FSGS. In this study, MCD was the most common primary GN observed overall from this part of India. MN was the most common GN in individuals above 20 years of age presenting with the nephrotic syndrome. The geographical and regional differences in the pattern of GNs point to the necessity of having a central biopsy registry.

    In the few studies available, the risk of developing systemic reactions (SR) to hymenoptera stings in patients with previous large local reactions (LLRs) to stings ranges from 0 to 7 %. We evaluated both retrospectively and prospectively the risk of SRs in patients with LLRs to stings. An overall number of 477 patients, 396 with an SR as the first manifestation of allergy and 81 with a history of only LLRs after hymenoptera stings, were included in the study. All patients had clinical history and allergy testing (skin tests and/or specific IgE) indicative of allergy to venom of only one kind of Hymenoptera. Of the 81 patient with LLRs, 53 were followed-up for 3 years by annual control visits, while the 396 patients with SR were evaluated retrospectively. Among the 396 patients with an SR, only 17 (4.2 %) had had a previous LLR as debut of allergy, after an history of normal local reactions to Hymenoptera stings. All the 81 patients with a history of only LLRs had previously had at least two LLRs, with an overall number of 238 stings and no SR. Among the 53 patients who were prospectively evaluated we found that 31 of them (58.3 %) were restung by the same type of insect, with an overall number of 59 stings, presenting only LLRs and no SR. Our findings confirm that patients with repeated LLRs to stings had no risk of SR, while a single LLR does not exclude such risk. This has to be considered in the management of patients with LLRs.

    Full Text Available Objective: To develop and evaluate predictive models by quantifying warning signs prior to the development of severe dengue. Methods: A retrospective cohort study was conducted in which the total number of warning signs each day was compared between dengue with warning signs and severe dengue. Multivariate logistic regression with forward likelihood ratio method was employed to achieve the best fit models for the prediction of severe dengue. The models were also being explored by adding diarrhoea and removing lethargy. Receiver operating characteristics were then used in these best fit models to identify suitable cut-off probability values derived from the equation of the models. Results: Median age of patients was 26 years old (interquartile range was 15 years and 65.3% (1 110 were males. Age with total number of warning signs at day one of illness (model T1 and age with total number of warning signs at day two of illness (model T2 were identified as the best fit models. The best probability cut-offs for model T1 was 0.050 6 with 10.1% positive predictive value, 96.4% negative predictive value, 99.4% sensitivity, 1.8% specificity; for model T2 was 0.050 3 with 10.2% positive predictive value, 96.4% negative predictive value, 99.4% sensitivity, 1.8% specificity. Conclusions: The models developed in this study might not reduce the burden effectively. Clinicians may use the models but the models must be re-validated in their clinical settings as the effect size might vary. Furthermore, the risk and benefit in selecting the cut-off values should be evaluated before implementing such models.

    Full Text Available Background: Snakebite is a serious public health problem in the world. The annual incidence of snakebites ranges from 4.5-9.1 in 100,000 population in Iran. With regard to diversity of envenomation profiles in different geographical parts of Iran, the aim of this study was to determine the demographical data, clinical and laboratory findings, and the outcome of the snakebite victims referred to a tertiary referral hospital. Methods: In this retrospective, cross-sectional study in Loghman Hakim Hospital Poisoning Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran, during a four-year period from March 2007 to March 2011. The demographic data, clinical manifestations, paraclinical findings, treatments performed before hospital admission, time elapsed between the bite and hospital admission, total dose of antivenom and the patients’ outcomes were investigated. Results: Seventy cases (58 males, 12 females were evaluated. Most of the cases (79% were older than 20 year old. The most common bite site was upper extremity (67%. Most of the patients were admitted within 5 h after the snakebite. The most common local and systemic manifestations were swelling (90%, pain (81.4%, nausea and vomiting (24.3%. Leukocytosis (35.7% and thrombocytopenia (25.7% were the most common laboratory abnormalities. Most of the patients (97.1% were treated with antivenom. Fifty percent of the patients only received 3-5 vials of antivenom. The mortality rate was 1.4%. Necrosis of the toes and compartment syndrome were the only serious complications. Conclusion: The findings emphasize the importance of early admission to the hospital and treatment with antivenom to avoid morbidity and mortality.

    A retrospective, descriptive study of clients with shoulder dysfunction referred to physical therapy. To (1) describe the clinical and functional outcomes of clients with shoulder dysfunction following outpatient physical therapy, and (2) to compare the outcomes by type of shoulder dysfunction. Although individuals with shoulder dysfunction are commonly referred to physical therapy few large descriptive studies regarding outcomes following physical therapy are available. Data for 878 clients (468 female, 410 male) were retrieved and analyzed. This database was developed between 1997 and 2000 and included 4 outpatient facilities from 1 healthcare system in the southwest corner of Michigan. Clients were classified by type of shoulder dysfunction, and standardized tests were performed upon admittance and discharge to physical therapy. Descriptive and inferential statistics were calculated for all data. Of all clients, 55.1% had shoulder impingement, while 18.3% had postoperative repair, 8.9% had a frozen shoulder, 7.6% had a rotator cuff tear, 3.0% had shoulder instability, 2.1% were post fracture, and the remaining 4.9% had miscellaneous diagnoses. The average (+/-SD) age of the patients was 53.6 +/- 16.4 years, with an average (+/-SD) number of treatment sessions of 13.7 +/- 11.0. All groups showed significant changes following physical therapy intervention. Clients with diverse types of shoulder dysfunction demonstrated improvement in both clinical and functional measures at the conclusion of physical therapy, although it is not possible to determine whether these changes were due to the interventions or due to time. The type of shoulder dysfunction appears to affect the prognosis, thus expected outcomes should be based upon initial diagnosis and specific measures.
